Moderate amount of time online helps teens to better cope with stressful events

Wed, 08/25/2021 - 13:39
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.

Study could provide a new therapeutic target to reduce COVID-19 mortality

Wed, 08/25/2021 - 12:52
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.

Study: Women smoke fewer cigarettes than men but find it more difficult to quit

Wed, 08/25/2021 - 12:40
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.

Novel CT scan-based approach indicates possible lung destruction in some people with asthma

Wed, 08/25/2021 - 12:34
A novel CT scan-based approach has revealed significant changes in a parameter indicating lung destruction in some asthmatics.

Periodontitis associated with increased risk of cardiovascular disease

Wed, 08/25/2021 - 12:28
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.

Mediterranean diet consumption linked with improvements in erectile dysfunction

Wed, 08/25/2021 - 12:24
A Mediterranean diet is associated with improvements in erectile dysfunction, according to research presented at ESC Congress 2021.

Aerobic exercise combined with tDCS improves the gait of Parkinson's patients

Wed, 08/25/2021 - 12:08
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.

Researchers explore how to optimally control diseases in prison population using rapid tests

Wed, 08/25/2021 - 11:52
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.

Scientists forecast healthcare burden of future COVID waves

Wed, 08/25/2021 - 11:17
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.

Study focuses on understanding how muscle fatigue and changes in gait affect older adults

Wed, 08/25/2021 - 11:03
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.

Study on SARS-CoV-2 Delta breakthrough infections shows twice the risk as Alpha

Wed, 08/25/2021 - 10:58
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.

Implementing healthy habits early can help stave off weight gain in college students

Wed, 08/25/2021 - 10:51
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.

New Binghamton research explores how brain folds form in fetuses

Wed, 08/25/2021 - 10:38
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.

Study reveals stable usage of drugs by adolescents in the first six months of the pandemic

Wed, 08/25/2021 - 10:28
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.

Two studies on gastrointestinal stroma tumors describe advances that may lead to new treatments

Wed, 08/25/2021 - 10:15
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.

Reassuring news about the protection that SARS-CoV-2 vaccines offer

Wed, 08/25/2021 - 10:03
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).

Study: Majority of hospital-acquired COVID-19 cases were contracted from other patients

Wed, 08/25/2021 - 09:54
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.

SARS-CoV-2 Delta likely to acquire resistance to wild-type spike vaccines

Wed, 08/25/2021 - 09:03
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.

Compounds from medicinal mushrooms may be our future weapon against SARS-CoV-2

Wed, 08/25/2021 - 08:29
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.
