What ’s new with the flu shot?

Should you get the influenza (flu) vaccine this year? The short, quick answer (barring any medical reasons you shouldn’t, such as severe allergies), is yes! But recent research raises another important question: When should you get the shot? Why a flu shot every year in the first place? Getting infected with the flu can be dangerous — we’ve seen patients in the ICU who were previously healthy but had a horrible response to a strain of the virus and became very sick. Every year the Centers for Disease Control and Prevention (CDC) and other agencies release flu vaccination guidelines in late summer to early fall. The flu vaccines are usually available by the end of the summer season. Figuring out exactly which strains of flu viruses the vaccine should protect against is often complicated. Basically, experts look at the influenza virus strains that were making trouble in previous years, and attempt to predict which strains are likely to cause the flu in the upcoming season. The inactivated flu vaccine is the form of flu vaccine that is most commonly injected and contains parts of the virus but no live virus. Therefore, you should not be infected with the flu from the vaccine itself. Some people may feel “sick” after the vaccine with symptoms such as mild fever, pain in the injection site, fatigue — all of which may just be your body mounting an expected immune response against the foreign virus particles. For the 2017-18 season, the CDC and Ad...

One of the worst symptoms of any plague is uncertainty—who it will strike, when it will end, why it began. Merely understanding a pandemic does not stop it, but an informed public can help curb its impact and slow its spread. It can also provide a certain ease of mind in a decidedly uneasy time. Here are some of the most frequently asked questions about the COVID-19 pandemic from TIME’s readers, along with the best and most current answers science can provide. A note about our sourcing: While there are many, many studies underway investigating COVID-19 and SARS-CoV-19, the novel coronavirus that causes the illn...

In this study, we sought to further characterize ILC2s in the kidney, their location within this organ and determine their functional role in IRI using a loss-of-function approach. Here, we found that kidney ILC2s constitutively express IL-5 and are primarily located in close proximity to the renal vasculature, within the adventitia. Additionally, we demonstrate that a reduction, deficiency or depletion of ILC2s had minimal impact on the severity of IRI. Whilst activation of ILC2s and the associated amplification of local type 2 immunity has been previously shown to reduce the deleterious consequences of AKI, our results r...

Conclusion This paper summarizes the current findings regarding the anti-colitis activity of plant-derived alkaloids and shows how these alkaloids exhibit significant and beneficial effects in alleviating colonic inflammation. These natural alkaloids are not only promising agents for IBD treatment but are also components for developing new wonder drugs. However, the underlying molecular mechanisms or toxicological evaluation of most plant-derived alkaloids still require much scientific research, and their actual efficacies for IBD patients have not been verified well in field research. Thus, further clinical trials to elu...

The 2017-2018 flu season was a bad one. The dominant viral strain, H3N2, was a particularly severe form of influenza, leading to widespread and serious illness across the country. The flu and its complications killed around 80,000 people last year, the CDC estimates, including 180 children. That’s the highest flu death toll in four decades. Experts say early indications suggest that this year’s flu season will be milder, but the memory of last winter should still serve as motivation to get the flu shot this fall. Here’s what you need to know about the 2018 flu shot. When should I get the flu shot? The CD...

“Life is too short to be miserable.” – Rita Mae Brown While it would be wonderful if you never got sick, that’s not life. In fact, you can count on having some bouts of illness no matter how healthy you currently are or have been. There are countless opportunities to encounter germs, carried by people who are infected — even if they don’t look sick — or clinging to surfaces you touch. Allergies afflict millions every day, while family contact and heredity account for many more instances of sickness and illness. When you do fall ill, it may be of short duration or a long and dr...

Follow me on Twitter @RobShmerling Ever wonder what other people are wondering about? I know I do. So, here are the top 10 health searches in Google for 2017. And just so you don’t have to look each one up, I’ve provided a brief answer. You’re welcome. 1.  What causes hiccups? I was surprised this one made it to the top 10 list of health searches. Maybe this search is common because hiccups are as mysterious as they are universal. I’ve written about hiccups before, but let’s just say the cause in any individual person is rarely known or knowable. Then again, the reason hiccups stop is als...

Follow me on Twitter @drClaire We started giving flu shots at our practice last week, and it made me not just happy, but relieved. I know how bad influenza can be and I always feel better when we can start preventing it. Every year, influenza sickens millions, hospitalizes hundreds of thousands, and kills tens of thousands. This is not your average common cold. While it is especially dangerous for anyone who already has a health problem (such as a weakened immune system, or heart or lung problems), it can be dangerous for healthy people, too. Even if you don’t get that sick from the flu, aside from missing school or ...

Discussion α-1-Antitrypsin Deficiency (A1AT) is a common single-gene mutation disease that is homozygous recessive. The normal allele is called M and the most common abnormal allele is Z. There are other alleles though. The gene codes for one of the primary protease inhibitors in the serum, thus those who are homozygous for the Z gene are sometimes referred to as “PIZZ” or “PIZ.” α-1-Antitrypsin is found in all body tissues but is especially important in the serum and lung. As noted it is one of the primary neutrophil protease inhibitors in the serum, and acts to neutralize these enzymes...

Discussion Fatigue is a subjective feeling of decreased energy, tiredness or feeling of exhaustion. Lethargy is often used synonymously, but lethargy is a state of being drowsiness or sleepy, and implies mental status changes. Both can cause the person to be apathetic or less active. Fatigue is a common state that almost everyone experiences multiple times in his or her lifetime. For most people it is a relatively acute or short-term chronic problem, often with a relatively easily identifiable problem cause, such as inadequate sleep, acute illness, or overexertion. For some, it can be less readily identifiable such as dep...

The approval of first-of-a-kind drugs rose last year to forty-one, resulting in the highest level of newly approved U.S. drugs in nineteen years. The total number of new drugs approved last year was even higher at sixty-nine. The rising figures reflect an industry-wide desire to research and develop drugs for rare and hard-to-treat diseases. The newly approved drugs serve to advance medical care and the health of patients suffering from many ailments, including various forms of cancer, heart failure, and cystic fibrosis. Additionally, more than 40% of the new therapies were approved for treatment of rare or "orphan&...
