Burden of asymptomatic pertussis in infants is greater than previously thought

New study challenges long-standing assumptions about disease severity in infants, and suggests that standard qPCR interpretations underestimate the true burden of other highly contagious diseases, such as COVID-19 and influenza.

Could wastewater epidemiology help track the circulation of SARS-CoV-2 variants?

In a new study, released as a preprint on the medRxiv* server, researchers from Germany, Italy and Netherlands demonstrated the utility of integrating genomic and wastewater based epidemiology (WBE) to provide unprecedented insight into the abundance of SARS-CoV-2 and the profile of the mutations associated with the VOCs (i.e., B.1.1.7, B.1.351, P.1, and B.1.617.2) in the wastewater samples.

What impacts public compliance with COVID-19 restrictions?

New research by scientists at Switzerland's Institute for Environmental Decisions reports that risk perception and public acceptance of NPIs depends on both worldview and levels of social trust. The study also found that, paradoxically, when the number of cases decreased in the period between the first and second waves, public willingness to comply with these measures fell.

Toxicant profile of BAT's modern oral products is comparable to nicotine replacement therapies

New research published today indicates that BAT's modern oral (MO) products in the form of tobacco-free nicotine pouches have a toxicant profile that is comparable to nicotine replacement therapies (NRTs) and much lower than traditional oral snus, a category of products that, when used as the sole nicotine product is already established as a reduced risk product compared with cigarettes.

Long-term exposure to poor air quality increases COVID-19 risk, research finds

Even as governments across the United States consider lifting mask mandates and relaxing preventative measures as vaccination numbers creep up, new research from a UCLA-led team has found that such basic techniques significantly reduce the risk of getting COVID-19.

UMSOM researchers receive $5 million federal grant to improve use of genetic risk scores

Researchers at the University of Maryland School of Medicine (UMSOM) have received a $5 million federal grant to pool genomic information from existing and new datasets - predominantly in African and African American populations -- in order to calculate the risk of developing specific diseases.

Chatbots for dementia patient or caregiver support need more work

Chatbots hold promise for dementia patient or caregiver support, but are still in their infancy, finds a paper published in the Journal of Medical Internet Research.

New antibody testing study finds evidence of early COVID-19 infections in the U.S.

A new antibody testing study examining samples originally collected through the National Institutes of Health's All of Us Research Program found evidence of SARS-CoV-2 infections in five states earlier than had initially been reported.

Does SARS-CoV-2 show seasonal variation in transmission in temperate countries?

The need to understand how and why such spread occurs is vital to containing it. A new medRxiv* preprint describes a significant reduction in transmission during the summer (by 42%), which is comparable to the impact of the most effective non-pharmaceutical intervention (NPI).

Being vaccinated doesn’t mean you must go maskless. Here’s why.

For more than a year, public health officials have repeatedly told us that masks save lives. They've warned us to keep our distance from our neighbors, who've morphed into disease vectors before our eyes.

Does the number of siblings you have affect your health?

News-Medical spoke to Professor Peter M Nilsson about cardiovascular disease risk and whether this is affected by the number of siblings you have.

Study: Genetic mutations associated with breast cancer risk are the same in Black and white women

The prevalence of genetic mutations associated with breast cancer in Black and white women is the same, according to a new JAMA Oncology study of nearly 30,000 patients led by researchers in the Basser Center for BRCA at the Abramson Cancer Center. About five percent of both Black and white women have a genetic mutation that increases their risk of breast cancer.

Delays and shortages hit SARS-CoV-2 genomic surveillance program

A new study from the Institute of Bioinformatics and Applied Biotechnology (IBAB), Bengaluru, India, provides an overview of how well this important monitoring mechanism is functioning around the world. The team has released their findings as a preprint on the bioRxiv* server.

Women now drink as much as men — and are prone to sickness sooner

Victoria Cooper thought her drinking habits in college were just like everyone else's. Shots at parties. Beers while bowling. Sure, she got more refills than some and missed classes while nursing hangovers, but she couldn't have a problem, she thought.

People with diabetes experiencing sleep disturbances have increased risk of death

Having trouble falling or staying asleep may leave you feeling tired and frustrated. It also could subtract years from your life expectancy, according to a new study from Northwestern Medicine and the University of Surrey in the United Kingdom (UK).

Mass vaccination the only way to tackle emerging SARS-CoV-2 variants

Researchers from Poland recently analyzed key information concerning SARS-CoV-2 variants, such as their infectivity, mutations, severity, and immune susceptibility. Their work is published in the open-access journal Pathogens.

Bacteria causing urinary tract infections can originate in meat-production chain

In young women, Staphylococcus saprophyticus is a main cause of urinary tract infections (UTI), reaching 20% prevalence. Understanding the epidemiology of this microorganism can help identify its origin, distribution, causes, and risk factors.

International coalition develops classification criteria for 25 subtypes of uveitis

An international coalition of eye researchers used machine learning to develop classification criteria for 25 of the most common types of uveitis, a collection of over 30 diseases characterized by inflammation inside the eye.

Single BioNTech/Pfizer vaccine dose reduces risk of COVID-19 by nearly 52%, matching clinical trial data

Data gathered from real-world vaccination programs following a single dose of Pfizer vaccine administration shows a reduction of 51.4% in infection risk and effectiveness of 54.4% against symptomatic coronavirus disease 2019 (COVID-19), matching clinical trial results.
