Risk of Guillain-Barré syndrome decreases after COVID-19 vaccination

A new study suggests that low GBS incidence in vaccinated patients compared to non-vaccinated people should encourage the active propagation of vaccination against SARS-CoV-2.

Eating before saliva collection may interfere with detection of SARS-CoV-2

A new study, published on the medRxiv* preprint server, has aimed to determine if children's diet impacts the detection of SARS-CoV-2 virus in saliva. Scientists performed diagnostic tests to detect this virus using real-time self-collected specimens provided by five healthy children. The samples were collected before and after eating selected foods. The specific time of collection of samples after eating were 0 minutes, 20 minutes, and 60 minutes after eating.

How fast has the Omicron strain been spreading in South Africa?

Scientists have shown the exponential growth of the Omicron strain found in Gauteng. They reported the doubling time of this strain to be equal to 3.38 days by analyzing its growth from November 8 to December 5, 2021. Based on the mutation accumulation profile, researchers revealed that this strain began to diverge between October 28 and November 5, 2021.

Climate change will affect bats hosting future coronaviruses, scientists predict

A new study led by David T. S. Hayman of Massey University in New Zealand details the creation of an ecological modeling pipeline to identify bat biodiversity data and patterns on bat distribution based on climate and landscape relationships.

Frequent cognitive impairments after 4-month follow-up in ICU COVID-19 patients

Results from a recent observational study published in the Journal Of The Neurological Sciences found that after a 4-month follow-up, ICU patients with severe COVID-19 illness were more likely to have mild cognitive impairment with features related to a diffuse encephalopathy than patients with mild infection who do not need a ventilator. Additionally, ICU patients experienced more significant impairment in executive function. All neurological deficits involve the peripheral nervous system.

Thrombosis may increase mortality risk in hospitalized COVID-19 patients

A team of US-based scientists has recently explored various risk factors associated with the poor prognosis of coronavirus disease 2019 (COVID-19). They have identified thrombosis-related risk factors as a major predictor of in-hospital COVID-19 related mortality. The study is currently available on the medRxiv* preprint server while awaiting peer review.

Increased troponin levels in the blood after surgery can be a sign of heart damage

After being anesthetized and undergoing major surgery, up to one in five patients have increased levels of the protein troponin in their blood. This can be a sign of heart damage.

New stroke treatment imitates the survival strategy of C. elegans

Each year, some 200,000 people in Germany and 1 million people in Europe suffer a stroke. This happens when blood clots obstruct major vessels and there is no longer sufficient supply of blood to the brain.

Study reveals the impact of HIV on COVID-19 disease

A new study found that during the early months of the COVID-19 pandemic people living with HIV were less likely to die from COVID than persons without HIV.

Study provides new insights into molecular drivers of treatment resistance in prostate cancer

An international research team co-led by scientists at Roswell Park Comprehensive Cancer Center and The Ohio State University Comprehensive Cancer Center – Arthur G. James Cancer Hospital and Richard J. Solove Research Institute has identified an important accelerator of treatment-resistant prostate cancer.

Parietooccipital fissure contributes to the invasion pattern of posterior medial temporal gliomas

Researchers from four academic neurosurgical centers in Japan found that the parietooccipital fissure, which divides the temporal, occipital, and parietal lobes of the brain, acts as an obstacle that may result in less invasion of posterior medial temporal gliomas toward the occipital lobe.

Survey finds increase in American adults skipping medical care due to cost

Nearly one-third (30%) of Americans skipped needed medical care in the past three months due to cost, the highest reported number since the COVID-19 pandemic began and a threefold increase from March to October, according to the latest survey from the nonprofit, nonpartisan organization West Health and Gallup, the global analytics and advice firm.
