New research published in the journal Clinical Psychological Science reveals that teenagers (ages 13–17) in low socioeconomic settings who spend a moderate amount of time online after a stressful experience deal with adversity far better than those who spend many hours online or avoid digital technology altogether.
An enzyme with an elusive role in severe inflammation may be a key mechanism driving COVID-19 severity and could provide a new therapeutic target to reduce COVID-19 mortality, according to a study published in the Journal of Clinical Investigation.
A study of more than 35,000 smokers has found that women smoke fewer cigarettes than men but are less likely to quit. The research is presented at ESC Congress 2021.
A novel CT scan-based approach has revealed significant changes in a parameter indicating lung destruction in some asthmatics.
Gum disease is associated with an increased risk of cardiovascular disease: the more severe the periodontitis, the higher the risk. The findings are presented at ESC Congress 2021.
A Mediterranean diet is associated with improvements in erectile dysfunction, according to research presented at ESC Congress 2021.
Transcranial direct current stimulation (tDCS) can increase the benefits of aerobic exercise and improve the gait of patients with Parkinson's disease immediately after a session. Step time variability decreases, reaction time shortens, and executive control of gait is enhanced.
The use of rapid tests to screen for diseases in prisons could enable the diagnosis of asymptomatic individuals and reduce the spread of infection. Victor Riquelme, Pedro Gajardo, and Diego Vicencio (all from the Universidad Técnica Federico Santa María in Chile) recently explored how to optimally control a communicable disease inside a prison population using inexpensive, low-complexity rapid tests that personnel can administer with only basic training.
The findings indicate that given the lower vaccine efficacy against the SARS-CoV-2 delta variant, France may face a large epidemic wave infecting 25% of the general population even with a 95% vaccine coverage. This, in turn, could affect the healthcare system in terms of hospital bed occupancy. The study is currently available on the medRxiv* preprint server.
Older adults on a walk or hike, or just going about their daily routines, seem to experience greater fatigue than their younger counterparts. Such fatigue may ultimately affect their ability to participate in activities that are meaningful to them and help keep them healthy.
A recent study conducted by Portuguese scientists has claimed that mRNA-based coronavirus disease 2019 (COVID-19) vaccines are less effective against the delta variant of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Moreover, in breakthrough infections by delta variant, vaccines are less effective in reducing viral loads. The study is currently available on the medRxiv* preprint server.
Everyone's heard about the so-called freshman 15, but new research from the University of Georgia suggests that counteracting this weight gain might be more complicated than just taking a walk around the quad.
Many mysteries continue to surround the human brain, but among the most important are how it forms and how those early weeks affect the rest of a person's life.
The advent of the COVID-19 pandemic, which began in earnest in the United States in early 2020, affected different demographic groups in different ways.
Gastrointestinal stroma tumors (GIST) are cancers that start in specialized nerve cells found in the digestive system, from the esophagus and stomach to the intestines and rectum.
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccines have proven effective at preventing COVID-19-related mortality and illness. Since no vaccine is 100% effective, breakthrough infections are likely to occur. New research by a group of scientists at Erasmus Medical Center and Radboud University in the Netherlands looked at vaccine-breakthrough infections in a large group of vaccinated healthcare workers (HCWs).
The majority of patients who contracted COVID-19 while in the hospital did so from other patients rather than from healthcare workers, concludes a new study from researchers at the University of Cambridge and Addenbrooke's Hospital.
A new study published on the preprint server bioRxiv* explores the mechanism of the Delta variant's high infectivity and suggests a plausible pathway by which the Delta variant could escape from vaccine-induced immunity.
Certain steroid-like compounds from Taiwan's endemic medicinal mushrooms (known as antcins) may inhibit a host cell receptor for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and, thus, prevent viral infection and subsequent development of the coronavirus disease (COVID-19), reports a new study published in the MDPI's journal Plants.
In the nearly 1 million Americans living with multiple sclerosis, the fatty substance that insulates the nerves of the central nervous system—called myelin—is damaged.
