Study reveals coadministered COVID-19 and flu vaccines effective, especially in seniors

The study in JAMA Network Open evaluates the effectiveness of simultaneously administering the Pfizer-BioNTech BNT162b2 BA.4/5 COVID-19 vaccine and seasonal influenza vaccines versus separate administration. Results suggest similar or slightly increased COVID-19 outcomes and lower influenza-related outcomes with coadministration, particularly in those aged 65 and above.

One in five individuals taking nirmatrelvir-ritonavir therapy found to experience rebound COVID

A new study by investigators from Mass General Brigham found that one in five individuals taking Nirmatrelvir-ritonavir therapy, commonly known as Paxlovid, to treat severe symptoms of COVID-19, experienced a positive test result and shedding of live and potentially contagious virus following an initial recovery and negative test - a phenomenon known as virologic rebound.

Hospital-acquired COVID-19 mortality drops in Omicron era post-vaccination, reveals Swedish study

In a study published in JAMA Network Open, researchers found that hospital-acquired SARS-CoV-2 infections in Stockholm led to increased 30-day mortality in the pre-vaccination period but showed significantly lower mortality during the Omicron wave post-vaccination. The study underscores the importance of vaccination in reducing mortality risks from nosocomial SARS-CoV-2 infections.

Study reveals no neuroinflammation in long COVID patients with neuropsychiatric symptoms

In a JAMA Network Open study, researchers found no evidence of neuroinflammation or blood-brain barrier dysfunction in cerebrospinal fluid markers of individuals with post-COVID-19 condition and neuropsychiatric symptoms compared to controls. The study, which assessed cytokines, chemokines, and neuroinflammation markers, suggests that persistent central nervous system immune activation may not be the primary driver of neurological long COVID symptoms.

Young people begin to use nicotine through vaping rather than through cigarettes

Young adults are now more likely to vape than to use traditional cigarettes. After years of public health success in decreasing the numbers of people using cigarettes, researchers are seeing striking increases in the numbers of young people who use e-cigarettes regularly – so much so that, for the first time, there are more young people who begin to use nicotine through vaping rather than through cigarettes.

"Christchurch mutation" can block detrimental effects of Alzheimer’s risk factor

Researchers at Gladstone Institutes have discovered that a rare genetic variant known as the "Christchurch mutation" can block detrimental effects of apolipoprotein E4, the best-established risk factor for the most common form of Alzheimer's disease.

Optimal hydration post-exercise: Study compares sodium and carbohydrate levels in sports drinks for effective rehydration

In this study, researchers compared the effectiveness of sports drinks with varying carbohydrate and sodium levels for rehydrating athletes post-exercise, finding that drinks with higher sodium and lower carbohydrate content were more effective for rapid and complete rehydration. The study highlighted the importance of beverage composition in athlete recovery and hydration strategies.

Intensive blood pressure treatment lowers risk of cardiovascular events in high-risk patients

An intensive three-year intervention to lower the top blood pressure number to less than 120 mm Hg was more effective at preventing death, heart attack, stroke and other cardiovascular events in adults at high risk for cardiovascular disease, compared to the standard treatment target of under 140 mm Hg, according to late-breaking science presented today at the American Heart Association's Scientific Sessions 2023.

Study finds rapid blood pressure reduction with low-sodium diet

Reducing daily sodium intake by around 4,000 mg/day significantly lowered systolic blood pressure in more than 70% of adults, ages 50 to 75, in as little as one week compared to their usual diet, according to late-breaking science presented today at the American Heart Association's Scientific Sessions 2023.

Intensive blood pressure control reduces dementia risk in adults with hypertension

An intensive, four-year blood-pressure intervention significantly reduced the risk of developing dementia among adults with high blood pressure compared to people who received usual care, in a study reported as late-breaking science today at the American Heart Association's Scientific Sessions 2023.

Early life stress circumstances alter more genes in the brain than head injuries

A surprising thing happened when researchers began exploring whether early-life stress compounds the effects of a childhood head injury on health and behavior later in life: In an animal study, stress changed the activation level of many more genes in the brain than were changed by a bump to the head.
