A simple coffee and a quick catnap could be the cure for staying alert on the nightshift as new research from the University of South Australia shows that this unlikely combination can improve attention and reduce sleep inertia.In Australia, more than 1.4 million people are employed in shift work, with more than 200,000 regularly working night or evening shifts.Lead researcher, Dr Stephanie Centofanti from UniSA Online and the Sleep and Chronobiology Laboratory at UniSA says the finding could help counteract the kind of sleep inertia that is experienced by many shiftworkers."Shift workers are often chronically sleep-deprived because they have disrupted and irregular sleep patterns," Dr Centofanti says."As a result, they can you buy sustiva over the counter commonly use a range of strategies to try to boost their alertness while on the nightshift, and these can include taking power naps and drinking coffee -- yet it's important to understand that there are disadvantages for both."Many workers nap during a night shift because they get so tired. But the downside is that they can experience 'sleep can you buy sustiva over the counter inertia' -- that grogginess you have just after you wake up -- and this can impair their performance and mood for up to an hour after their nap."Caffeine is also used by many people to stay awake and alert. But again, if you have too much coffee it can harm your overall sleep and health. And, if you use it can you buy sustiva over the counter to perk you up after a nap, it can take a good 20-30 minutes to kick in, so there's a significant time delay before you feel the desired effect."A 'caffeine-nap' (or 'caff-nap') could be a viable alternative -- by drinking a coffee before taking a nap, shiftworkers can gain the benefits of a 20-30-minute nap then the perk of the caffeine when they wake. It's a win-win."The small pilot study tested the impact of 200 mg of caffeine (equivalent to 1-2 regular cups of coffee) consumed by participants just before a 3.30am 30-minute nap, comparing results with a group that took a placebo.Participants taking a 'caffeine-nap' showed marked improvements in both performance and alertness, indicating the potential of a 'caffeine-nap' to counteract sleep grogginess.Dr Centofanti says this shows a promising fatigue countermeasure for shift workers.

She says the can you buy sustiva over the counter next move is to test the new finding on more people. Story Source can you buy sustiva over the counter.

Content may be edited for style and length.A study of a gateway receptor for SARS-CoV-2 led by Walter Lukiw, PhD, Professor of Neuroscience, Neurology and Ophthalmology at LSU Health New Orleans' Neuroscience Center of Excellence and School of Medicine, may help explain the wide variety of symptoms and organs involved with SARS-CoV-2 infection and COVID-19.

The results suggest that a multi-organ infection with SARS-CoV-2 may be via the angiotensin-converting enzyme 2 (ACE2) receptor, which is found almost everywhere throughout the body. The findings are published in the journal Cellular and Molecular Neurobiology.To better understand the mechanism and pathways of SARS-CoV-2 infection and susceptibility to specific cell and tissue types as well as organ systems, the research team analyzed 85 human tissues for the presence of ACE2 receptors. ACE2 is a protein that is found on the surface of many immune and nonimmune cell types. An enzyme, it is part of the system that regulates blood pressure and fluid and electrolyte balance. It may also help regulate cardiovascular, neurovascular and renal function, as well as fertility.

ACE2 receptors act like locks on cells, and the SARS-CoV-2 spike proteins act like keys that open the locks letting the virus enter cells to rapidly multiply. As well as controls, tissues tested included lung, digestive, renal-excretory, reproductive, eye tissues, and 21 different regions of the brain."Besides strong ACE2 expression in respiratory, digestive, renal-excretory and reproductive cells, high ACE2 expression was also found in the amygdala, cerebral cortex and brainstem," reports Dr. Lukiw. "This may help explain cognitive deficits associated with SARS-CoV-2 infection. Some of the highest ACE2 expression levels were found in the pons and medulla oblongata in the human brainstem, an anatomical region of the brain containing the medullary respiratory centers, and this may in part explain the susceptibility of many CoV-19 patients to severe respiratory distress."The team further noted that ACE2 receptor activity was also easily detected in the eye, suggesting that the visual system may provide an additional entry point for SARS-CoV-2 invasion and that under certain conditions, eyeglasses or face shields may be as important as face masks in reducing SARS-CoV-2 transmission and infection."Several important research gaps remain," Lukiw concludes.

"A real danger of SARS-CoV-2 infection is not only its highly transmissible and contagious nature and lethality, but also its simultaneous and multipronged attack on many human cell and tissue types involving vital and critical respiratory, immunological, vascular, renal-excretory and neural systems as well as an unprecedented coordinated disruption of the complex neurophysiology, neurochemistry, neurobiology and neurology of the cells of the brain and central nervous system (CNS) that normally regulate these multiple physiological systems."The authors credit the late Dr. James M. Hill (formerly a Professor in the Departments of Microbiology, Ophthalmology and Pharmacology at LSU Health New Orleans School of Medicine) with whom they had a longstanding research collaboration on the expression of the ACE2 receptors, including those found in the Alzheimer's disease brain. Aileen Pogue, from Alchem Biotech Research in Toronto, also participated in the research data tabulation, bioinformatics and statistical analysis.The research was supported by grants from Research to Prevent Blindness (RPB).

La temporada de influenza se verá diferente este año, ya que los Estados Unidos se enfrentan a una pandemia de coronavirus que ya ha matado a más de 176.000 personas.Muchos estadounidenses son reacios a ir al médico y los funcionarios de salud pública temen que las personas eviten vacunarse. Aunque a veces se considera incorrectamente como un resfriado, la gripe también mata a decenas de miles de personas en el país cada año. Los más vulnerables son los niños pequeños, los adultos mayores y las personas con enfermedades subyacentes.

Cuando se combina con los efectos de COVID-19, los expertos en salud pública dicen que es más importante que nunca vacunarse contra la gripe.Si una cantidad suficiente de la población se vacuna, más del 45% lo hizo la temporada de gripe pasada, podría ayudar a evitar un escenario de pesadilla este invierno, con hospitales llenos de pacientes con COVID-19 y los que sufren los efectos graves de la influenza.Además de la posible carga para los hospitales, existe la posibilidad de que las personas contraigan ambos virus y “nadie sabe qué sucede si se contrae influenza y COVID simultáneamente porque nunca sucedió antes”, dijo la doctora Rachel Levine, secretaria de Salud de Pennsylvania, a reporteros.En respuesta, este año los fabricantes están produciendo más suministros de vacunas, entre 194 y 198 millones de dosis, unas 20 millones más de las que se distribuyeron la temporada pasada, según los Centros para el Control y Prevención de Enfermedades (CDC).Mientras se acerca la temporada de gripe, aquí hay algunas respuestas a preguntas frecuentes:P. ¿Cuándo debo vacunarme contra la gripe?. La publicidad ya ha comenzado y algunas farmacias y clínicas ya tienen sus suministros. Pero, debido a que la efectividad de la vacuna puede disminuir con el tiempo, los CDC recomiendan no recibir la dosis en agosto.Muchas farmacias y clínicas comenzarán las inmunizaciones a principios de septiembre. Generalmente, los virus de la influenza comienzan a circular a mediados o fines de octubre, pero se expanden masivamente más tarde, en el invierno.

Se necesitan aproximadamente dos semanas después de recibir la inyección para que los anticuerpos, que circulan en la sangre y frustran las infecciones, se acumulen.“Las personas jóvenes y sanas pueden comenzar a vacunarse contra la gripe en septiembre, y las personas mayores y otras poblaciones vulnerables pueden hacerlo en octubre”, dijo el doctor Steve Miller, director clínico de la aseguradora Cigna.Los CDC recomiendan que las personas “se vacunen contra la influenza a fines de octubre”, pero señalaron que se puede recibir la vacuna más tarde porque “aún puede ser beneficiosas y la vacunación debe ofrecerse a lo largo de toda la temporada de influenza”.Aun así, algunos expertos recomiendan no esperar demasiado este año, no solo por COVID-19, sino también en caso de que haya escasez debido a la abrumadora demanda.P. ¿Cuáles son las razones por las que las que debería ofrecer mi brazo para vacunarme?. Hay que vacunarse porque brinda protección contra la gripe y, por lo tanto, contra la propagación a otras personas, lo que puede ayudar a disminuir la carga para los hospitales y el personal médico.Y hay otro mensaje que puede resonar en estos tiempos extraños.“Le da a la gente la sensación de que hay algunas cosas que pueden controlar”, dijo Eduardo Sánchez, director médico de prevención de la American Heart Association.Si bien una vacuna contra la gripe no evitará COVID-19, recibirla podría ayudar al médico a diferenciar entre las dos enfermedades si se desarrolla algún síntoma (fiebre, tos, dolor de garganta) que ambas infecciones comparten, explicó Sánchez.Y aunque las vacunas contra la gripe no evitarán todos los casos de gripe, vacunarse puede reducir la gravedad si la persona se enferma, dijo.Todas las personas elegibles, especialmente los trabajadores esenciales, los que sufren de afecciones subyacentes y aquellos en mayor riesgo, incluidos los niños muy pequeños y las mujeres embarazadas, deben buscar protección, dijeron los CDC. La entidad recomienda la vacunación a partir de los 6 meses.P. ¿Qué sabemos sobre la efectividad de la vacuna de este año?.

Se deben producir nuevas vacunas contra la gripe cada año, porque el virus muta y la efectividad de la vacuna varía, dependiendo de qué tan bien coincida con el virus circulante.Se calculó que la formulación del año pasado tuvo una eficacia de aproximadamente un 45% para prevenir la gripe en general, con una efectividad de aproximadamente un 55% en los niños. Las vacunas disponibles en el país este año tienen como objetivo prevenir al menos tres cepas diferentes del virus, y la mayoría cubre cuatro.Todavía no se sabe qué tan bien coincidirá el suministro de este año con las cepas que circularán en los Estados Unidos. Las primeras indicaciones del hemisferio sur, que atraviesa su temporada de gripe durante nuestro verano, son alentadoras. Allí, las personas practicaron el distanciamiento social, usaron máscaras y se vacunaron en mayor número este año, y los niveles mundiales de gripe son más bajos de lo esperado. Sin embargo, expertos advierten que no se debe contar con una temporada igual de suave en los Estados Unidos, en parte porque los esfuerzos por usar mascara facial y de distanciamiento social varían ampliamente.P.

¿Qué están haciendo diferente los seguros y sistemas de salud este año?. Las aseguradoras y los sistemas de salud contactados por KHN dicen que seguirán las pautas de los CDC, que exigen limitar y espaciar la cantidad de personas que esperan en las filas y las áreas de vacunación. Algunos están programando citas para vacunas contra la gripe para ayudar a controlar el flujo.Health Fitness Concepts, una compañía que trabaja con UnitedHealth Group y otras empresas para establecer clínicas de vacunación contra la gripe en el noreste del país, dijo que está “fomentando eventos más pequeños y frecuentes para apoyar el distanciamiento social” y “exigiendo que se completen todos los formularios y arremangarse las camisas antes de entrar al área de vacunación contra la influenza”.Se requerirá que todos usen máscaras.Además, a nivel nacional, algunos grupos médicos contratados por UnitedHealth instalarán carpas, para que las inyecciones se puedan administrar al aire libre, dijo un vocero.Kaiser Permanente planifica las vacunas directamente en autos en algunos de sus centros médicos y está probando los procedimientos de detección y registro sin contacto en algunos lugares.Geisinger Health, un proveedor de salud regional en Pennsylvania y Nueva Jersey, dijo que también tendría programas de vacunación contra la influenza al aire libre en sus instalaciones.Además, “Geisinger exige que todos los empleados reciban la vacuna contra la influenza este año”, dijo Mark Shelly, director de prevención y control de infecciones del sistema. €œAl dar este paso, esperamos transmitir a nuestros vecinos la importancia de la vacuna contra la influenza para todos”.P. Por lo general, me vacunan contra la gripe en el trabajo.

¿Seguirá siendo una opción este año?. Con el objetivo de evitar riesgosas reuniones en interiores, muchos empleadores se muestran reacios a patrocinar las clínicas de gripe en oficinas como han ofrecido en años anteriores. Y con tanta gente que sigue trabajando desde casa, hay menos necesidad de llevar las vacunas contra la gripe al lugar de trabajo. En cambio, muchos empleadores están alentando a los trabajadores a que reciban vacunas de sus médicos de atención primaria, en farmacias u otros entornos comunitarios. El seguro generalmente cubrirá el costo de la vacuna.Algunos empleadores están considerando ofrecer cupones para vacunas contra la gripe a sus trabajadores sin seguro o a aquellos que no participan en el plan médico de la compañía, dijo Julie Stone, directora general de salud y beneficios de Willis Towers Watson, una firma consultora.Estos cupones podrían, por ejemplo, permitir a los trabajadores obtener la vacuna en un laboratorio en particular sin costo.Algunos empleadores están comenzando a pensar en cómo podrían usar sus estacionamientos para administrar vacunas contra la gripe enlos autos, dijo el doctor David Zieg, líder de servicios clínicos para el consultor de beneficios Mercer.Aunque la ley federal permite a los empleadores exigir a los empleados que se vacunen contra la gripe, ese paso generalmente lo toman solo los centros de atención médica y algunas universidades donde las personas viven y trabajan en estrecha colaboración, dijo Zieg.Pero sucede.

El mes pasado, el sistema de la Universidad de California emitió una orden ejecutiva que requiere que todos los estudiantes, profesores y personal se vacunen contra la gripe antes del 1 de noviembre, con limitadas excepciones.P. ¿Qué están haciendo las farmacias para alentar a las personas a vacunarse contra la gripe?. Algunas farmacias están haciendo un esfuerzo adicional para salir a la comunidad y ofrecer vacunas contra la gripe.Walgreens, que tiene casi 9,100 farmacias en todo el país, continúa una asociación iniciada en 2015 con organizaciones comunitarias, iglesias y empleadores que ha ofrecido alrededor de 150,000 clínicas de gripe móviles hasta la fecha.El programa pone especial énfasis en trabajar con poblaciones vulnerables y en áreas desatendidas, dijo el doctor Kevin Ban, director médico de la cadena de farmacias.Walgreens comenzó a ofrecer vacunas contra la gripe a mediados de agosto y está animando a las personas a no demorar en vacunarse.Tanto Walgreens como CVS están estimulando a las personas a programar citas y hacer trámites en línea este año para minimizar el tiempo que pasan en los locales.En los CVS MinuteClinic, una vez que los pacientes se han registrado para recibir la vacuna contra la gripe, deben esperar afuera o en su automóvil, ya que las áreas de espera interiores ahora están cerradas.“No tenemos un arsenal contra COVID”, dijo Ban, de Walgreens. €œPero quitar la presión del sistema de atención médica proporcionando vacunas por adelantado es algo que sí podemos hacer”.

jappleby@kff.org, @Julie_Appleby Michelle Andrews. andrews.khn@gmail.com, @mandrews110 Related Topics Insurance Noticias En Español Public Health CDC COVID-19 Insurers VaccinesThis story was produced in partnership with PolitiFact. This story can be republished for free (details). President Donald Trump accepted the Republican Party’s nomination for president in a 70-minute speech from the South Lawn of the White House on Thursday night.Speaking to a friendly crowd that didn’t appear to be observing social distancing conventions, and with few participants wearing masks, he touched on a range of topics, including many related to the COVID pandemic and health care in general.Throughout, the partisan crowd applauded and chanted “Four more years!. € And, even as the nation’s COVID-19 death toll exceeded 180,000, Trump was upbeat. €œIn recent months, our nation and the entire planet has been struck by a new and powerful invisible enemy,” he said.

€œLike those brave Americans before us, we are meeting this challenge.”At the end of the event, there were fireworks.Our partners at PolitiFact did an in-depth fact check on Trump’s entire acceptance speech. Here are the highlights related to the administration’s COVID-19 response and other health policy issues:“We developed, from scratch, the largest and most advanced testing system in the world.” This is partially right, but it needs context.It’s accurate that the U.S. Developed its COVID-19 testing system from scratch, because the government didn’t accept the World Health Organization’s testing recipe. But whether the system is the “largest” or “most advanced” is subject to debate.The U.S. Has tested more individuals than any other country.

But experts told us a more meaningful metric would be the percentage of positive tests out of all tests, indicating that not only sick people were getting tested. Another useful metric would be the percentage of the population that has been tested. The U.S. Is one of the most populous countries but has tested a lower percentage of its population than other countries. Don't Miss A Story Subscribe to KHN’s free Weekly Edition newsletter.

The U.S. Was also slower than other countries in rolling out tests and amping up testing capacity. Even now, many states are experiencing delays in reporting test results to positive individuals.As for “the most advanced,” Trump may be referring to new testing investments and systems, like Abbott’s recently announced $5, 15-minute rapid antigen test, which the company says will be about the size of a credit card, needs no instrumentation and comes with a phone app through which people can view their results. But Trump’s comment makes it sound as if these testing systems are already in place when they haven’t been distributed to the public.“The United States has among the lowest [COVID-19] case fatality rates of any major country in the world. The European Union’s case fatality rate is nearly three times higher than ours.”The case fatality rate measures the known number of cases against the known number of deaths.

The European Union has a rate that’s about 2½ times greater than the United States.But the source of that data, Oxford University’s Our World in Data project, reports that “during an outbreak of a pandemic, the case fatality rate is a poor measure of the mortality risk of the disease.”A better way to measure the threat of the virus, experts say, is to look at the number of deaths per 100,000 residents. Viewed that way, the U.S. Has the 10th-highest death rate in the world.“We will produce a vaccine before the end of the year, or maybe even sooner.”It’s far from guaranteed that a coronavirus vaccine will be ready before the end of the year.While researchers are making rapid strides, it’s not yet known precisely when the vaccine will be available to the public, which is what’s most important. Six vaccines are in the third phase of testing, which involves thousands of patients. Like earlier phases, this one looks at the safety of a vaccine but also examines its effectiveness and collects more data on side effects.

Results of the third phase will be submitted to the Food and Drug Administration for approval.The government website Operation Warp Speed seems less optimistic than Trump, announcing it “aims to deliver 300 million doses of a safe, effective vaccine for COVID-19 by January 2021.”And federal health officials and other experts have generally predicted a vaccine will be available in early 2021. Federal committees are working on recommendations for vaccine distribution, including which groups should get it first. €œFrom everything we’ve seen now — in the animal data, as well as the human data — we feel cautiously optimistic that we will have a vaccine by the end of this year and as we go into 2021,” said Dr. Anthony Fauci, the nation’s top infectious diseases expert. €œI don’t think it’s dreaming.”“Last month, I took on Big Pharma.

You think that is easy?. I signed orders that would massively lower the cost of your prescription drugs.”Quite misleading. Trump signed four executive orders on July 24 aimed at lowering prescription drug prices. But those orders haven’t taken effect yet — the text of one hasn’t even been made publicly available — and experts told us that, if implemented, the measures would be unlikely to result in significant drug price reductions for the majority of Americans.“We will always and very strongly protect patients with preexisting conditions, and that is a pledge from the entire Republican Party.”Trump’s pledge is undermined by his efforts to overturn the Affordable Care Act, the only law that guarantees people with preexisting conditions both receive health coverage and do not have to pay more for it than others do. In 2017, Trump supported congressional efforts to repeal the ACA.

The Trump administration is now backing GOP-led efforts to overturn the ACA through a court case. And Trump has also expanded short-term health plans that don’t have to comply with the ACA.“Joe Biden recently raised his hand on the debate stage and promised he was going to give it away, your health care dollars to illegal immigrants, which is going to bring a massive number of immigrants into our country.”This is misleading. During a June 2019 Democratic primary debate, candidates were asked. €œRaise your hand if your government plan would provide coverage for undocumented immigrants.” All candidates on stage, including Biden, raised their hands. They were not asked if that coverage would be free or subsidized.Biden supports extending health care access to all immigrants, regardless of immigration status.

A task force recommended that he allow immigrants who are in the country illegally to buy health insurance, without federal subsidies.“Joe Biden claims he has empathy for the vulnerable, yet the party he leads supports the extreme late-term abortion of defenseless babies right up to the moment of birth.”This mischaracterizes the Democratic Party’s stance on abortion and Biden’s position.Biden has said he would codify the Supreme Court’s ruling in Roe v. Wade and related precedents. This would generally limit abortions to the first 20 to 24 weeks of gestation. States are allowed under court rulings to ban abortion after the point at which a fetus can sustain life, usually considered to be between 24 and 28 weeks from the mother’s last menstrual period — and 43 states do. But the rulings require states to make exceptions “to preserve the life or health of the mother.” Late-term abortions are very rare, about 1%.The Democratic Party platform holds that “every woman should have access to quality reproductive health care services, including safe and legal abortion — regardless of where she lives, how much money she makes, or how she is insured.” It does not address late-term abortion.PolitiFact’s Daniel Funke, Jon Greenberg, Louis Jacobson, Noah Y.

"A real danger of SARS-CoV-2 infection is not only its highly transmissible and contagious nature and lethality, but also its simultaneous and multipronged attack on many human cell and tissue types involving vital and critical respiratory, immunological, vascular, renal-excretory and neural systems as well as an unprecedented coordinated disruption of the complex neurophysiology, neurochemistry, neurobiology and neurology of the cells of the brain and central nervous system (CNS) that normally regulate these multiple physiological systems."The authors credit the late Dr. James M. Hill (formerly a Professor in the Departments of Microbiology, Ophthalmology and Pharmacology at LSU Health New Orleans School of Medicine) with whom they had a longstanding research collaboration on the expression of the ACE2 receptors, including those found in the Alzheimer's disease brain.

La temporada de influenza se verá diferente este año, ya que los Estados Unidos se enfrentan a una pandemia de coronavirus que ya ha matado a más de 176.000 personas.Muchos estadounidenses son reacios a ir al médico y los funcionarios de salud pública temen que las personas eviten vacunarse. Aunque a veces se considera incorrectamente como un resfriado, la gripe también mata a decenas de miles de personas en el país cada año. Los más vulnerables son los niños pequeños, los adultos mayores y las personas con enfermedades subyacentes.

Cuando se combina con los efectos de COVID-19, los expertos en salud pública dicen que es más importante que nunca vacunarse contra la gripe.Si una cantidad suficiente de la población se vacuna, más del 45% lo hizo la temporada de gripe pasada, podría ayudar a evitar un escenario de pesadilla este invierno, con hospitales llenos de pacientes con COVID-19 y los que sufren los efectos graves de la influenza.Además de la posible carga para los hospitales, existe la posibilidad de que las personas contraigan ambos virus y “nadie sabe qué sucede si se contrae influenza y COVID simultáneamente porque nunca sucedió antes”, dijo la doctora Rachel Levine, secretaria de Salud de Pennsylvania, a reporteros.En respuesta, este año los fabricantes están produciendo más suministros de vacunas, entre 194 y 198 millones de dosis, unas 20 millones más de las que se distribuyeron la temporada pasada, según los Centros para el Control y Prevención de Enfermedades (CDC).Mientras se acerca la temporada de gripe, aquí hay algunas respuestas a preguntas frecuentes:P. ¿Cuándo debo vacunarme contra la gripe?. La publicidad ya ha comenzado y algunas farmacias y clínicas ya tienen sus suministros. Pero, debido a que la efectividad de la vacuna puede disminuir con el tiempo, los CDC recomiendan no recibir la dosis en agosto.Muchas farmacias y clínicas comenzarán las inmunizaciones a principios de septiembre. Generalmente, los virus de la influenza comienzan a circular a mediados o fines de octubre, pero se expanden masivamente más tarde, en el invierno.

Se necesitan aproximadamente dos semanas después de recibir la inyección para que los anticuerpos, que circulan en la sangre y frustran las infecciones, se acumulen.“Las personas jóvenes y sanas pueden comenzar a vacunarse contra la gripe en septiembre, y las personas mayores y otras poblaciones vulnerables pueden hacerlo en octubre”, dijo el doctor Steve Miller, director clínico de la aseguradora Cigna.Los CDC recomiendan que las personas “se vacunen contra la influenza a fines de octubre”, pero señalaron que se puede recibir la vacuna más tarde porque “aún puede ser beneficiosas y la vacunación debe ofrecerse a lo largo de toda la temporada de influenza”.Aun así, algunos expertos recomiendan no esperar demasiado este año, no solo por COVID-19, sino también en caso de que haya escasez debido a la abrumadora demanda.P. ¿Cuáles son las razones por las que las que debería ofrecer mi brazo para vacunarme?. Hay que vacunarse porque brinda protección contra la gripe y, por lo tanto, contra la propagación a otras personas, lo que puede ayudar a disminuir la carga para los hospitales y el personal médico.Y hay otro mensaje que puede resonar en estos tiempos extraños.“Le da a la gente la sensación de que hay algunas cosas que pueden controlar”, dijo Eduardo Sánchez, director médico de prevención de la American Heart Association.Si bien una vacuna contra la gripe no evitará COVID-19, recibirla podría ayudar al médico a diferenciar entre las dos enfermedades si se desarrolla algún síntoma (fiebre, tos, dolor de garganta) que ambas infecciones comparten, explicó Sánchez.Y aunque las vacunas contra la gripe no evitarán todos los casos de gripe, vacunarse puede reducir la gravedad si la persona se enferma, dijo.Todas las personas elegibles, especialmente los trabajadores esenciales, los que sufren de afecciones subyacentes y aquellos en mayor riesgo, incluidos los niños muy pequeños y las mujeres embarazadas, deben buscar protección, dijeron los CDC. La entidad recomienda la vacunación a partir de los 6 meses.P. ¿Qué sabemos sobre la efectividad de la vacuna de este año?.

Se deben producir nuevas vacunas contra la gripe cada año, porque el virus muta y la efectividad de la vacuna varía, dependiendo de qué tan bien coincida con el virus circulante.Se calculó que la formulación del año pasado tuvo una eficacia de aproximadamente un 45% para prevenir la gripe en general, con una efectividad de aproximadamente un 55% en los niños. Las vacunas disponibles en el país este año tienen como objetivo prevenir al menos tres cepas diferentes del virus, y la mayoría cubre cuatro.Todavía no se sabe qué tan bien coincidirá el suministro de este año con las cepas que circularán en los Estados Unidos. Las primeras indicaciones del hemisferio sur, que atraviesa su temporada de gripe durante nuestro verano, son alentadoras. Allí, las personas practicaron el distanciamiento social, usaron máscaras y se vacunaron en mayor número este año, y los niveles mundiales de gripe son más bajos de lo esperado. Sin embargo, expertos advierten que no se debe contar con una temporada igual de suave en los Estados Unidos, en parte porque los esfuerzos por usar mascara facial y de distanciamiento social varían ampliamente.P.

¿Qué están haciendo diferente los seguros y sistemas de salud este año?. Las aseguradoras y los sistemas de salud contactados por KHN dicen que seguirán las pautas de los CDC, que exigen limitar y espaciar la cantidad de personas que esperan en las filas y las áreas de vacunación. Algunos están programando citas para vacunas contra la gripe para ayudar a controlar el flujo.Health Fitness Concepts, una compañía que trabaja con UnitedHealth Group y otras empresas para establecer clínicas de vacunación contra la gripe en el noreste del país, dijo que está “fomentando eventos más pequeños y frecuentes para apoyar el distanciamiento social” y “exigiendo que se completen todos los formularios y arremangarse las camisas antes de entrar al área de vacunación contra la influenza”.Se requerirá que todos usen máscaras.Además, a nivel nacional, algunos grupos médicos contratados por UnitedHealth instalarán carpas, para que las inyecciones se puedan administrar al aire libre, dijo un vocero.Kaiser Permanente planifica las vacunas directamente en autos en algunos de sus centros médicos y está probando los procedimientos de detección y registro sin contacto en algunos lugares.Geisinger Health, un proveedor de salud regional en Pennsylvania y Nueva Jersey, dijo que también tendría programas de vacunación contra la influenza al aire libre en sus instalaciones.Además, “Geisinger exige que todos los empleados reciban la vacuna contra la influenza este año”, dijo Mark Shelly, director de prevención y control de infecciones del sistema. €œAl dar este paso, esperamos transmitir a nuestros vecinos la importancia de la vacuna contra la influenza para todos”.P. Por lo general, me vacunan contra la gripe en el trabajo.

¿Seguirá siendo una opción este año?. Con el objetivo de evitar riesgosas reuniones en interiores, muchos empleadores se muestran reacios a patrocinar las clínicas de gripe en oficinas como han ofrecido en años anteriores. Y con tanta gente que sigue trabajando desde casa, hay menos necesidad de llevar las vacunas contra la gripe al lugar de trabajo. En cambio, muchos empleadores están alentando a los trabajadores a que reciban vacunas de sus médicos de atención primaria, en farmacias u otros entornos comunitarios. El seguro generalmente cubrirá el costo de la vacuna.Algunos empleadores están considerando ofrecer cupones para vacunas contra la gripe a sus trabajadores sin seguro o a aquellos que no participan en el plan médico de la compañía, dijo Julie Stone, directora general de salud y beneficios de Willis Towers Watson, una firma consultora.Estos cupones podrían, por ejemplo, permitir a los trabajadores obtener la vacuna en un laboratorio en particular sin costo.Algunos empleadores están comenzando a pensar en cómo podrían usar sus estacionamientos para administrar vacunas contra la gripe enlos autos, dijo el doctor David Zieg, líder de servicios clínicos para el consultor de beneficios Mercer.Aunque la ley federal permite a los empleadores exigir a los empleados que se vacunen contra la gripe, ese paso generalmente lo toman solo los centros de atención médica y algunas universidades donde las personas viven y trabajan en estrecha colaboración, dijo Zieg.Pero sucede.

El mes pasado, el sistema de la Universidad de California emitió una orden ejecutiva que requiere que todos los estudiantes, profesores y personal se vacunen contra la gripe antes del 1 de noviembre, con limitadas excepciones.P. ¿Qué están haciendo las farmacias para alentar a las personas a vacunarse contra la gripe?. Algunas farmacias están haciendo un esfuerzo adicional para salir a la comunidad y ofrecer vacunas contra la gripe.Walgreens, que tiene casi 9,100 farmacias en todo el país, continúa una asociación iniciada en 2015 con organizaciones comunitarias, iglesias y empleadores que ha ofrecido alrededor de 150,000 clínicas de gripe móviles hasta la fecha.El programa pone especial énfasis en trabajar con poblaciones vulnerables y en áreas desatendidas, dijo el doctor Kevin Ban, director médico de la cadena de farmacias.Walgreens comenzó a ofrecer vacunas contra la gripe a mediados de agosto y está animando a las personas a no demorar en vacunarse.Tanto Walgreens como CVS están estimulando a las personas a programar citas y hacer trámites en línea este año para minimizar el tiempo que pasan en los locales.En los CVS MinuteClinic, una vez que los pacientes se han registrado para recibir la vacuna contra la gripe, deben esperar afuera o en su automóvil, ya que las áreas de espera interiores ahora están cerradas.“No tenemos un arsenal contra COVID”, dijo Ban, de Walgreens. €œPero quitar la presión del sistema de atención médica proporcionando vacunas por adelantado es algo que sí podemos hacer”.

This story can be republished for free (details). President Donald Trump accepted the Republican Party’s nomination for president in a 70-minute speech from the South Lawn of the White House on Thursday night.Speaking to a friendly crowd that didn’t appear to be observing social distancing conventions, and with few participants wearing masks, he touched on a range of topics, including many related to the COVID pandemic and health care in general.Throughout, the partisan crowd applauded and chanted “Four more years!. € And, even as the nation’s COVID-19 death toll exceeded 180,000, Trump was upbeat. €œIn recent months, our nation and the entire planet has been struck by a new and powerful invisible enemy,” he said.

€œLike those brave Americans before us, we are meeting this challenge.”At the end of the event, there were fireworks.Our partners at PolitiFact did an in-depth fact check on Trump’s entire acceptance speech. Here are the highlights related to the administration’s COVID-19 response and other health policy issues:“We developed, from scratch, the largest and most advanced testing system in the world.” This is partially right, but it needs context.It’s accurate that the U.S. Developed its COVID-19 testing system from scratch, because the government didn’t accept the World Health Organization’s testing recipe. But whether the system is the “largest” or “most advanced” is subject to debate.The U.S. Has tested more individuals than any other country.

But experts told us a more meaningful metric would be the percentage of positive tests out of all tests, indicating that not only sick people were getting tested. Another useful metric would be the percentage of the population that has been tested. The U.S. Is one of the most populous countries but has tested a lower percentage of its population than other countries. Don't Miss A Story Subscribe to KHN’s free Weekly Edition newsletter.

The U.S. Was also slower than other countries in rolling out tests and amping up testing capacity. Even now, many states are experiencing delays in reporting test results to positive individuals.As for “the most advanced,” Trump may be referring to new testing investments and systems, like Abbott’s recently announced $5, 15-minute rapid antigen test, which the company says will be about the size of a credit card, needs no instrumentation and comes with a phone app through which people can view their results. But Trump’s comment makes it sound as if these testing systems are already in place when they haven’t been distributed to the public.“The United States has among the lowest [COVID-19] case fatality rates of any major country in the world. The European Union’s case fatality rate is nearly three times higher than ours.”The case fatality rate measures the known number of cases against the known number of deaths.

The European Union has a rate that’s about 2½ times greater than the United States.But the source of that data, Oxford University’s Our World in Data project, reports that “during an outbreak of a pandemic, the case fatality rate is a poor measure of the mortality risk of the disease.”A better way to measure the threat of the virus, experts say, is to look at the number of deaths per 100,000 residents. Viewed that way, the U.S. Has the 10th-highest death rate in the world.“We will produce a vaccine before the end of the year, or maybe even sooner.”It’s far from guaranteed that a coronavirus vaccine will be ready before the end of the year.While researchers are making rapid strides, it’s not yet known precisely when the vaccine will be available to the public, which is what’s most important. Six vaccines are in the third phase of testing, which involves thousands of patients. Like earlier phases, this one looks at the safety of a vaccine but also examines its effectiveness and collects more data on side effects.

Results of the third phase will be submitted to the Food and Drug Administration for approval.The government website Operation Warp Speed seems less optimistic than Trump, announcing it “aims to deliver 300 million doses of a safe, effective vaccine for COVID-19 by January 2021.”And federal health officials and other experts have generally predicted a vaccine will be available in early 2021. Federal committees are working on recommendations for vaccine distribution, including which groups should get it first. €œFrom everything we’ve seen now — in the animal data, as well as the human data — we feel cautiously optimistic that we will have a vaccine by the end of this year and as we go into 2021,” said Dr. Anthony Fauci, the nation’s top infectious diseases expert. €œI don’t think it’s dreaming.”“Last month, I took on Big Pharma.

You think that is easy?. I signed orders that would massively lower the cost of your prescription drugs.”Quite misleading. Trump signed four executive orders on July 24 aimed at lowering prescription drug prices. But those orders haven’t taken effect yet — the text of one hasn’t even been made publicly available — and experts told us that, if implemented, the measures would be unlikely to result in significant drug price reductions for the majority of Americans.“We will always and very strongly protect patients with preexisting conditions, and that is a pledge from the entire Republican Party.”Trump’s pledge is undermined by his efforts to overturn the Affordable Care Act, the only law that guarantees people with preexisting conditions both receive health coverage and do not have to pay more for it than others do. In 2017, Trump supported congressional efforts to repeal the ACA.

The Trump administration is now backing GOP-led efforts to overturn the ACA through a court case. And Trump has also expanded short-term health plans that don’t have to comply with the ACA.“Joe Biden recently raised his hand on the debate stage and promised he was going to give it away, your health care dollars to illegal immigrants, which is going to bring a massive number of immigrants into our country.”This is misleading. During a June 2019 Democratic primary debate, candidates were asked. €œRaise your hand if your government plan would provide coverage for undocumented immigrants.” All candidates on stage, including Biden, raised their hands. They were not asked if that coverage would be free or subsidized.Biden supports extending health care access to all immigrants, regardless of immigration status.

A task force recommended that he allow immigrants who are in the country illegally to buy health insurance, without federal subsidies.“Joe Biden claims he has empathy for the vulnerable, yet the party he leads supports the extreme late-term abortion of defenseless babies right up to the moment of birth.”This mischaracterizes the Democratic Party’s stance on abortion and Biden’s position.Biden has said he would codify the Supreme Court’s ruling in Roe v. Wade and related precedents. This would generally limit abortions to the first 20 to 24 weeks of gestation. States are allowed under court rulings to ban abortion after the point at which a fetus can sustain life, usually considered to be between 24 and 28 weeks from the mother’s last menstrual period — and 43 states do. But the rulings require states to make exceptions “to preserve the life or health of the mother.” Late-term abortions are very rare, about 1%.The Democratic Party platform holds that “every woman should have access to quality reproductive health care services, including safe and legal abortion — regardless of where she lives, how much money she makes, or how she is insured.” It does not address late-term abortion.PolitiFact’s Daniel Funke, Jon Greenberg, Louis Jacobson, Noah Y.

Buy sustiva with prescription

Etchells E, buy sustiva with prescription Ho M, Shojania KG. Value of small sample sizes in rapid-cycle quality improvement projects. BMJ Qual Safe 2016;25:202–6.The buy sustiva with prescription article has been corrected since it was published online.

The authors want to alert readers to the following error identified in the published version. The error is in the last paragraph of the section “Small samples can make ‘rapid improvement’ Rapid”, wherein the minimum sample size has been considered as six instead of eight.For this first (convenience) sample of 10 volunteer users, buy sustiva with prescription 5/10 (50%) completed the form without any input or instructions. The other five became frustrated and gave up.

Table 1 tells you that, with an observed success rate of 50% and a desired target of 90%, any audit with a sample of six or more allows you to confidently reject the null hypothesis that your form is working at a 90% success rate.For decades, those working in hospitals buy sustiva with prescription normalised the incessant alarms from medical devices as a necessary, almost comforting, reality of a high tech industry. While nurses drowned in excessive, frequently uninformative alarms, other members of the healthcare team often paid little attention. Fortunately, times are changing and managing alarm fatigue is now buy sustiva with prescription a key patient safety priority in acute care environments.1Adverse patient events from alarm fatigue, particularly related to excessive physiological monitor alarms, have received widespread attention over the last decade, including from the news media.2–5 In the USA, hospitals redoubled alarm safety efforts following the 2013 Joint Commission Sentinel Event Alert and subsequent National Patient Safety Goals on alarm safety.1 2 6 We are now beginning to understand how to reduce excessive non-actionable alarms (including invalid alarms as well as those that are valid but not actionable or informative),7 8 better manage alarm notifications and ultimately improve patient safety.

Alarm data are readily available and measuring alarm response time during patient care is possible.7 9 Yet we have few high-quality reports describing clear improvement to clinical alarm burden, and most published interventions are of limited scope, duration or both.10 11 To demonstrate value in alarm quality improvement (QI) efforts moving forward, we need more rigorous evidence for interventions and more meaningful outcome measures.In this issue of BMJ Quality and Safety, Pater et al12 report the results of a comprehensive multidisciplinary alarm management QI project executed over 3½ years in a 17-bed paediatric acute care cardiology unit. The primary project goal was to reduce alarm notifications from continuous buy sustiva with prescription bedside monitoring. Although limited to a single unit, the project is an important contribution to the scant literature on alarm management in paediatric settings for three reasons.

First, the initiative lasted longer than most that have been reported, which allowed for tailoring of alarm interventions to the needs of the unit and patient population and measuring the impacts and sustainability over time. Second, the scope of the intervention bundle encompassed a wide variety buy sustiva with prescription of changes including adoption of a smartphone notification system. Addition of time delays between when alarm thresholds are violated and when an alarm notification is issued.

Implementation of an alarm notification escalation algorithm after a certain buy sustiva with prescription amount of time in alarm threshold violation. Deactivation of numerous technical alarms (such as respiratory lead detachment). Monitoring of electrode lead replacement buy sustiva with prescription every 24 hours.

And discussion of alarm parameters on daily rounds. Third, the authors introduced a novel strategy for reducing the stress that alarms may cause patients and families by deactivating inroom alarm audio, although no outcomes were reported attributable directly to this component of the intervention.This project constitutes an important contribution to the published literature buy sustiva with prescription. However, Pater et al faced two challenges that are ubiquitous in the field of clinical alarm management.

(1) Identification buy sustiva with prescription of meaningful outcome measures and (2) Lack of high-quality evidence for most interventions. With regards to the first challenge, the primary outcome measure used in the study comprised ‘initial alarm notifications’, defined as the first notification of a monitor alarm delivered to the nurse’s mobile device. Although initial alarm notifications declined by 68% following the intervention, these notifications accounted for only about half of all alarm notifications.

The other half included second and third notifications for alarms exceeding specified delay thresholds, which were sent both to the buy sustiva with prescription mobile device of the primary nurse and to ‘buddy’ nurses, potentially increasing alarm burden. On the other hand, eliminating inroom audible alarms may have reduced the perceived alarm burden for nurses compared with having both bedside and mobile device notifications. Determining the true benefit of a reduction in a subset of alarms presents complex challenges.Alarm frequency is the most commonly used outcome measure in alarm research and QI projects, but reduction in alarms does not necessarily indicate improved buy sustiva with prescription patient safety or a highly functional alarm management system.

Alarm reduction could easily be achieved in an undesirable way by simply turning off alarms. Unfortunately, most studies have not been powered to statistically evaluate improvements in patient safety buy sustiva with prescription. (Pater et al did monitor patient safety balancing measures, which remained stable after intervention implementation).

To assess change in nurses’ perceptions of alarm frequency, Pater et al conducted a prepost survey, which despite the small sample size (n=38 buy sustiva with prescription preintervention and n=25 postintervention) managed to show improvement, with the percentage of nurses agreeing they could respond to alarms appropriately and quickly increasing from 32% to 76% (p<0.001). That said, this survey was not a validated measure of alarm fatigue. In fact, we currently have no widely accepted, buy sustiva with prescription validated tool for assessing alarm fatigue.11As we look towards future evaluations of alarm management strategies, the focus needs to shift away from simply reducing the frequency of alarms to more meaningful outcome metrics.

In addition to alarm rates, outcomes such as response time to actual patient alarms7 9 or to simulated alarms injected into real patient care environments13 may be better indicators of whether the entire alarm response system is functioning correctly. Larger, multisite studies are needed to assess patient outcomes.In addition to meaningful outcome measures, the second challenge for alarm QI projects is the lack of good evidence for alarm management interventions. Most alarm reduction interventions have not been systematically evaluated at all or only in small buy sustiva with prescription studies without a control group.10 11 As a result, alarm management projects tend to involve complex and costly bundles of interventions of uncertain benefit.

The cost of these interventions is due in part to the growing industry of technology solutions for alarm management. Some institutions have also made massive investments in personnel, such as monitor ‘watchers’ to help nurses identify buy sustiva with prescription actionable alarms, for which there is also little evidence.14Future alarm management QI initiatives will benefit from a higher quality evidence base for the growing list of potential alarm management interventions. Pragmatic trials that leverage meaningful outcome measures to assess alarm interventions are warranted.

In addition, we need to evaluate buy sustiva with prescription interventions that address the full spectrum of the alarm management system. Most alarm management interventions to date have focused primarily on filtering out non-actionable alarms. Far less emphasis has been placed on ensuring that the nurse receiving the notification is available to respond to the alarm, a prime opportunity for future work.Even if alarms are actionable, we know that nurses may not always respond quickly for a variety of reasons.7 15–17 Factors like insufficient buy sustiva with prescription staffing, high severity of illness on the unit and unbalanced nursing skill mix all likely contribute to inadequate alarm response.

In critical care, nurses have reported that the nature of their work requires that they function as a team to respond to one another’s alarms.15 Although not ideal, nurses have developed heuristics based on factors like family presence at the bedside to help them prioritise alarm response in hectic work environments.7 16 Emphasising outcomes like faster alarm response time without addressing systems factors risks trading one patient safety problem for another. We do not want to engender more frequent interruptions of high-risk activities, like medication administration,18 19 because nurses feel compelled to respond more quickly to alarms.The robust QI initiative carried out by Pater et al reflects the type of thoughtful approach needed to implement and tailor alarm management interventions for a buy sustiva with prescription particular unit, demonstrating a generalisable process for others to emulate. Ultimately, every alarm offers a potential benefit (opportunity to rescue a patient) and comes with a potential cost (eg, increased alarm fatigue, interruptions of other activities).

This trade-off needs to be optimised in the context of the individual unit, accounting for the unit-specific and systems factors that influence the cost of each additional alarm, including non-actionable alarm rates, unit layout, severity of illness and nurse staffing.17 20 With more robust outcome measures and more evidence to support interventions, we can increase the value of alarm QI initiatives and accelerate progress towards optimising alarm management systems.AcknowledgmentsWe thank Charles McCulloch, PhD (University of California, San Francisco) for comments on an early draft..

We do not want to engender more frequent interruptions of high-risk activities, like medication administration,18 19 because nurses feel compelled to respond more quickly to alarms.The robust QI initiative carried out by Pater et al reflects the type of thoughtful approach needed to implement and tailor alarm management sustiva street price interventions for a particular unit, demonstrating a generalisable process for others to emulate. Ultimately, every alarm offers a potential benefit (opportunity to rescue a patient) and comes with a potential cost (eg, increased alarm fatigue, interruptions of other activities).

This trade-off needs to be optimised in the context of the individual unit, accounting for the unit-specific and systems factors that influence the cost of each additional alarm, including non-actionable alarm rates, unit layout, severity of illness and nurse staffing.17 20 With more robust outcome measures and more evidence to support interventions, we can increase the value of alarm QI initiatives and accelerate progress towards optimising alarm management systems.AcknowledgmentsWe thank Charles McCulloch, PhD (University of California, San Francisco) for comments on an early draft..

About This TrackerThis tracker provides the number of confirmed cases and deaths from novel coronavirus by country, the trend in confirmed case and death counts by country, and a global map showing which sustiva pill price countries have confirmed cases and deaths. The data are drawn sustiva pill price from the Johns Hopkins University (JHU) Coronavirus Resource Center’s COVID-19 Map and the World Health Organization’s (WHO) Coronavirus Disease (COVID-2019) situation reports.This tracker will be updated regularly, as new data are released.Related Content. About COVID-19 CoronavirusIn late 2019, a new coronavirus emerged in central China to cause disease in humans. Cases of this disease, known as COVID-19, have sustiva pill price since been reported across around the globe.

On January 30, 2020, the World Health Organization (WHO) declared the virus represents a public health emergency of international concern, and on January 31, 2020, the U.S. Department of Health and Human Services declared it to be a health emergency for the United States.With schools sustiva pill price nationwide preparing for fall and the federal government encouraging in-person classes, key concerns for school officials, teachers and parents include the risks that coronavirus poses to children and their role in transmission of the disease.A new KFF brief examines the latest available data and evidence about the issues around COVID-19 and children and what they suggest about the risks posed for reopening classrooms. The review concludes that while children are much less likely than adults to sustiva pill price become severely ill, they can transmit the virus. Key findings include:Disease severity is significantly less in children, though rarely some do get very sick.

Children under age 18 account for 22% of the population but account for just 7% of the sustiva pill price more than 4 million COVID-19 cases and less than 1% of deaths.The evidence is mixed about whether children are less likely than adults to become infected when exposed. While one prominent study estimates children and teenagers are half as likely as adults over age 20 to catch the virus, other studies find children and adults are about equally likely to have antibodies that develop after a COVID-19 infection.While children do transmit to others, more evidence is needed on the frequency and extent of that transmission. A number of studies find children are less likely than adults to be the source of infections in households and other settings, though this could occur because of differences in testing, the severity of the disease, and the impact of sustiva pill price earlier school closures.Most countries that have reopened schools have not experienced outbreaks, but almost all had significantly lower rates of community transmission. Some countries, including Canada, Chile, France, and Israel did experience school-based outbreaks, sometimes significant ones, that required schools to close a second time.The analysis concludes that there is a risk of spread associated with reopening schools, particularly in states and communities where there is already widespread community transmission, that should be weighed carefully against the benefits of in-person education..

Etchells E, Ho M, Shojania KG buy sustiva online. Value of small sample sizes in rapid-cycle quality improvement projects. BMJ Qual buy sustiva online Safe 2016;25:202–6.The article has been corrected since it was published online. The authors want to alert readers to the following error identified in the published version.

The error is in the last paragraph of the section buy sustiva online “Small samples can make ‘rapid improvement’ Rapid”, wherein the minimum sample size has been considered as six instead of eight.For this first (convenience) sample of 10 volunteer users, 5/10 (50%) completed the form without any input or instructions. The other five became frustrated and gave up. Table 1 tells you that, with an observed success rate of 50% and a desired target of 90%, any audit with a sample of six or more allows you to confidently reject the null hypothesis that your form is working at buy sustiva online a 90% success rate.For decades, those working in hospitals normalised the incessant alarms from medical devices as a necessary, almost comforting, reality of a high tech industry. While nurses drowned in excessive, frequently uninformative alarms, other members of the healthcare team often paid little attention.

Fortunately, times are changing and managing alarm fatigue is now a key patient safety priority in acute care environments.1Adverse patient events from alarm fatigue, particularly related to excessive physiological monitor alarms, have received widespread attention over the last decade, including from the news media.2–5 In the USA, hospitals redoubled alarm safety efforts following the 2013 Joint Commission Sentinel Event Alert and subsequent National Patient Safety Goals on alarm safety.1 2 6 buy sustiva online We are now beginning to understand how to reduce excessive non-actionable alarms (including invalid alarms as well as those that are valid but not actionable or informative),7 8 better manage alarm notifications and ultimately improve patient safety. Alarm data are readily available and measuring alarm response time during patient care is possible.7 9 Yet we have few high-quality reports describing clear improvement to clinical alarm burden, and most published interventions are of limited scope, duration or both.10 11 To demonstrate value in alarm quality improvement (QI) efforts moving forward, we need more rigorous evidence for interventions and more meaningful outcome measures.In this issue of BMJ Quality and Safety, Pater et al12 report the results of a comprehensive multidisciplinary alarm management QI project executed over 3½ years in a 17-bed paediatric acute care cardiology unit. The primary project goal was to buy sustiva online reduce alarm notifications from continuous bedside monitoring. Although limited to a single unit, the project is an important contribution to the scant literature on alarm management in paediatric settings for three reasons.

First, the initiative lasted longer than most that have been reported, which allowed for tailoring of alarm interventions to the needs of the unit and patient population and measuring the impacts and sustainability over time. Second, the scope of the intervention bundle encompassed buy sustiva online a wide variety of changes including adoption of a smartphone notification system. Addition of time delays between when alarm thresholds are violated and when an alarm notification is issued. Implementation of an alarm notification escalation algorithm after a certain amount of time in alarm threshold violation buy sustiva online.

Deactivation of numerous technical alarms (such as respiratory lead detachment). Monitoring of electrode lead replacement every buy sustiva online 24 hours. And discussion of alarm parameters on daily rounds. Third, the authors introduced a novel strategy for reducing the stress that alarms may cause patients and families by deactivating inroom alarm audio, although no outcomes were reported attributable directly to this component of the buy sustiva online intervention.This project constitutes an important contribution to the published literature.

However, Pater et al faced two challenges that are ubiquitous in the field of clinical alarm management. (1) Identification of meaningful outcome measures and buy sustiva online (2) Lack of high-quality evidence for most interventions. With regards to the first challenge, the primary outcome measure used in the study comprised ‘initial alarm notifications’, defined as the first notification of a monitor alarm delivered to the nurse’s mobile device. Although initial alarm notifications declined by 68% following the intervention, these notifications accounted for only about half of all alarm notifications.

The other half included second and third notifications for alarms exceeding specified delay thresholds, which were sent both to the mobile device of the buy sustiva online primary nurse and to ‘buddy’ nurses, potentially increasing alarm burden. On the other hand, eliminating inroom audible alarms may have reduced the perceived alarm burden for nurses compared with having both bedside and mobile device notifications. Determining the true benefit of a reduction in a subset of alarms presents complex challenges.Alarm frequency is the most commonly buy sustiva online used outcome measure in alarm research and QI projects, but reduction in alarms does not necessarily indicate improved patient safety or a highly functional alarm management system. Alarm reduction could easily be achieved in an undesirable way by simply turning off alarms.

Unfortunately, most studies have not been powered buy sustiva online to statistically evaluate improvements in patient safety. (Pater et al did monitor patient safety balancing measures, which remained stable after intervention implementation). To assess change in nurses’ perceptions of alarm frequency, Pater et al conducted a prepost survey, which despite buy sustiva online the small sample size (n=38 preintervention and n=25 postintervention) managed to show improvement, with the percentage of nurses agreeing they could respond to alarms appropriately and quickly increasing from 32% to 76% (p<0.001). That said, this survey was not a validated measure of alarm fatigue.

In fact, we currently have no widely accepted, validated tool for assessing alarm fatigue.11As we look towards future evaluations of alarm management buy sustiva online strategies, the focus needs to shift away from simply reducing the frequency of alarms to more meaningful outcome metrics. In addition to alarm rates, outcomes such as response time to actual patient alarms7 9 or to simulated alarms injected into real patient care environments13 may be better indicators of whether the entire alarm response system is functioning correctly. Larger, multisite studies are needed to assess patient outcomes.In addition to meaningful outcome measures, the second challenge for alarm QI projects is the lack of good evidence for alarm management interventions. Most alarm reduction interventions have not been systematically buy sustiva online evaluated at all or only in small studies without a control group.10 11 As a result, alarm management projects tend to involve complex and costly bundles of interventions of uncertain benefit.

The cost of these interventions is due in part to the growing industry of technology solutions for alarm management. Some institutions have also made massive investments in personnel, such as monitor ‘watchers’ to help nurses identify buy sustiva online actionable alarms, for which there is also little evidence.14Future alarm management QI initiatives will benefit from a higher quality evidence base for the growing list of potential alarm management interventions. Pragmatic trials that leverage meaningful outcome measures to assess alarm interventions are warranted. In addition, we need to evaluate interventions that address the full spectrum buy sustiva online of the alarm management system.

Most alarm management interventions to date have focused primarily on filtering out non-actionable alarms. Far less emphasis has been placed on ensuring that the nurse receiving the notification is available to respond to the alarm, a prime opportunity for future work.Even if alarms are actionable, we know that nurses buy sustiva online may not always respond quickly for a variety of reasons.7 15–17 Factors like insufficient staffing, high severity of illness on the unit and unbalanced nursing skill mix all likely contribute to inadequate alarm response.

Most alarm reduction interventions have not been systematically evaluated sustiva street price at all or only in small studies without a control group.10 11 As a result, alarm management projects tend to involve complex and costly bundles of interventions of uncertain benefit.

The cost of these interventions is due in part to the growing industry of technology solutions for alarm management. Some institutions have also made massive investments in personnel, such as monitor ‘watchers’ to help nurses identify actionable alarms, for which there is also little evidence.14Future alarm management QI initiatives will benefit from a higher quality evidence base for sustiva street price the growing list of potential alarm management interventions. Pragmatic trials that leverage meaningful outcome measures to assess alarm interventions are warranted.

In addition, we need sustiva street price to evaluate interventions that address the full spectrum of the alarm management system. Most alarm management interventions to date have focused primarily on filtering out non-actionable alarms. Far less emphasis has been placed on ensuring that the nurse receiving the notification is available to respond to the alarm, a prime opportunity for future work.Even if alarms are actionable, we know that nurses may not always respond quickly for a variety of reasons.7 15–17 Factors like insufficient staffing, high severity of illness on the unit and unbalanced nursing skill mix all likely sustiva street price contribute to inadequate alarm response.

In critical care, nurses have reported that the nature of their work requires that they function as a team to respond to one another’s alarms.15 Although not ideal, nurses have developed heuristics based on factors like family presence at the bedside to help them prioritise alarm response in hectic work environments.7 16 Emphasising outcomes like faster alarm response time without addressing systems factors risks trading one patient safety problem for another. We do not want to engender more frequent interruptions of high-risk activities, like medication administration,18 19 because nurses feel compelled to respond more quickly to alarms.The robust QI initiative carried out by Pater et al reflects the type of thoughtful approach needed to implement and tailor alarm management interventions sustiva street price for a particular unit, demonstrating a generalisable process for others to emulate. Ultimately, every alarm offers a potential benefit (opportunity to rescue a patient) and comes with a potential cost (eg, increased alarm fatigue, interruptions of other activities).

This trade-off needs to be optimised in the context of the individual unit, accounting for the unit-specific and systems factors that influence the cost of each additional alarm, including non-actionable alarm rates, unit layout, severity of illness and nurse staffing.17 20 With more robust outcome measures and more evidence to support interventions, we can increase the value of alarm QI initiatives and accelerate progress towards optimising alarm management systems.AcknowledgmentsWe thank Charles McCulloch, PhD (University of California, San Francisco) for comments on an early draft..

IStock Share Fast Facts New @HopkinsMedicine study finds African-American women with common form of hair loss at increased risk of uterine fibroids - Click to Tweet New study in @JAMADerm shows most common form of alopecia (hair loss) in African-American women associated with higher risks of uterine fibroids - Click to Tweet In a study of medical records gathered on hundreds of thousands of African-American women, Johns Hopkins researchers say they have evidence that women with a common form of hair loss have an increased chance of developing uterine leiomyomas, or fibroids.In a report on the research, published in the December 27 issue of JAMA Dermatology, the researchers call on physicians who treat women with central centrifugal cicatricial alopecia (CCCA) to make patients aware that they may be at increased risk for fibroids and should be screened for the condition, particularly if they have symptoms such as heavy bleeding and pain. CCCA predominantly affects black women and is the most common form of permanent alopecia in this population.

The excess scar tissue that forms as a result of this type of hair loss may also explain the higher risk for uterine fibroids, which are characterized by fibrous growths in the lining of the womb. Crystal Aguh, M.D., assistant professor of dermatology at the Johns Hopkins University School of Medicine, says the scarring associated with CCCA is similar to the scarring associated with excess fibrous tissue elsewhere in the body, a situation that may explain why women with this type of hair loss are at a higher risk for fibroids.People of African descent, she notes, are more prone to develop other disorders of abnormal scarring, termed fibroproliferative disorders, such as keloids (a type of raised scar after trauma), scleroderma (an autoimmune disorder marked by thickening of the skin as well as internal organs), some types of lupus and clogged arteries. During a four-year period from 2013-2017, the researchers analyzed patient data from the Johns Hopkins electronic medical record system (Epic) of 487,104 black women ages 18 and over.

The prevalence of those with fibroids was compared in patients with and without CCCA. Overall, the researchers found that 13.9 percent of women with CCCA also had a history of uterine fibroids compared to only 3.3 percent of black women without the condition. In absolute numbers, out of the 486,000 women who were reviewed, 16,212 had fibroids.Within that population, 447 had CCCA, of which 62 had fibroids.

The findings translate to a fivefold increased risk of uterine fibroids in women with CCCA, compared to age, sex and race matched controls. Aguh cautions that their study does not suggest any cause and effect relationship, or prove a common cause for both conditions. €œThe cause of the link between the two conditions remains unclear,” she says.

However, the association was strong enough, she adds, to recommend that physicians and patients be made aware of it. Women with this type of scarring alopecia should be screened not only for fibroids, but also for other disorders associated with excess fibrous tissue, Aguh says. An estimated 70 percent of white women and between 80 and 90 percent of African-American women will develop fibroids by age 50, according to the NIH, and while CCCA is likely underdiagnosed, some estimates report a prevalence of rates as high as 17 percent of black women having this condition.

The New England Journal of Medicine Share Fast Facts This study clears up how big an effect the mutational burden has on outcomes to immune checkpoint inhibitors across many different cancer types. - Click to Tweet The number of mutations in a tumor’s DNA is a good predictor of whether it will respond to a class of cancer immunotherapy drugs known as checkpoint inhibitors. - Click to Tweet The “mutational burden,” or the number of mutations present in a tumor’s DNA, is a good predictor of whether that cancer type will respond to a class of cancer immunotherapy drugs known as checkpoint inhibitors, a new study led by Johns Hopkins Kimmel Cancer Center researchers shows.

The finding, published in the Dec. 21 New England Journal of Medicine, could be used to guide future clinical trials for these drugs. Checkpoint inhibitors are a relatively new class of drug that helps the immune system recognize cancer by interfering with mechanisms cancer cells use to hide from immune cells.

As a result, the drugs cause the immune system to fight cancer in the same way that it would fight an infection. These medicines have had remarkable success in treating some types of cancers that historically have had poor prognoses, such as advanced melanoma and lung cancer. However, these therapies have had little effect on other deadly cancer types, such as pancreatic cancer and glioblastoma.

The mutational burden of certain tumor types has previously been proposed as an explanation for why certain cancers respond better than others to immune checkpoint inhibitors says study leader Mark Yarchoan, M.D., chief medical oncology fellow. Work by Dung Le, M.D., associate professor of oncology, and other researchers at the Johns Hopkins Kimmel Cancer Center and its Bloomberg~Kimmel Cancer Institute for Cancer Immunotherapy showed that colon cancers that carry a high number of mutations are more likely to respond to checkpoint inhibitors than those that have fewer mutations. However, exactly how big an effect the mutational burden has on outcomes to immune checkpoint inhibitors across many different cancer types was unclear.

To investigate this question, Yarchoan and colleagues Alexander Hopkins, Ph.D., research fellow, and Elizabeth Jaffee, M.D., co-director of the Skip Viragh Center for Pancreas Cancer Clinical Research and Patient Care and associate director of the Bloomberg~Kimmel Institute, combed the medical literature for the results of clinical trials using checkpoint inhibitors on various different types of cancer. They combined these findings with data on the mutational burden of thousands of tumor samples from patients with different tumor types. Analyzing 27 different cancer types for which both pieces of information were available, the researchers found a strong correlation.

The higher a cancer type’s mutational burden tends to be, the more likely it is to respond to checkpoint inhibitors. More than half of the differences in how well cancers responded to immune checkpoint inhibitors could be explained by the mutational burden of that cancer. €œThe idea that a tumor type with more mutations might be easier to treat than one with fewer sounds a little counterintuitive.

It’s one of those things that doesn’t sound right when you hear it,” says Hopkins. €œBut with immunotherapy, the more mutations you have, the more chances the immune system has to recognize the tumor.” Although this finding held true for the vast majority of cancer types they studied, there were some outliers in their analysis, says Yarchoan. For example, Merkel cell cancer, a rare and highly aggressive skin cancer, tends to have a moderate number of mutations yet responds extremely well to checkpoint inhibitors.

However, he explains, this cancer type is often caused by a virus, which seems to encourage a strong immune response despite the cancer’s lower mutational burden. In contrast, the most common type of colorectal cancer has moderate mutational burden, yet responds poorly to checkpoint inhibitors for reasons that are still unclear. Yarchoan notes that these findings could help guide clinical trials to test checkpoint inhibitors on cancer types for which these drugs haven’t yet been tried.

Future studies might also focus on finding ways to prompt cancers with low mutational burdens to behave like those with higher mutational burdens so that they will respond better to these therapies. He and his colleagues plan to extend this line of research by investigating whether mutational burden might be a good predictor of whether cancers in individual patients might respond well to this class of immunotherapy drugs. €œThe end goal is precision medicine—moving beyond what’s true for big groups of patients to see whether we can use this information to help any given patient,” he says.
