A rapid, evidence-based review summarizes the effectiveness of cloth masks in protecting health care clinicians from respiratory viral infections, such as COVID-19. Nine studies were included in the review, and all but one were conducted prior to the COVID-19 pandemic. The only randomized trial of cloth face masks published at the time of this review compared the infection rates of influenza-like illness among groups of health care professionals who wore cloth masks, medical masks, or inconsistent mask use in the hospital setting.
Despite having some of the densest living spaces and the highest number of international visitors, Hong Kong, Singapore, and Beijing have utilized their respective primary health care systems to keep their COVID-19 cases and deaths relatively low. Researchers studied the primary health care systems in the three cities to identify features of each system that other cities can use as examples to prepare for and prevent deaths in future health crises.
Despite seeing gains in insurance coverage for preventive health services under the Affordable Care Act, the US has seen a declining rate of primary care visits over the past fifteen years. Are fewer individuals seeing primary care physicians? The authors of this study compared two factors that contribute to that decline to determine whether it was the number of primary care patients or the frequency of their clinical visits that contributed most to the overall decline.
Harmful medical practices, like inappropriate prescribing of opioids and racial and income-based discrimination in clinical settings, can vary across medical practices and individuals. Patients may find that even common primary care health services, like getting a chest x-rays or a referral to a heart or lung specialist, can differ widely depending on your doctor or clinic location.
A detailed description of how ovarian cancer cells adapt to survive and proliferate in the peritoneal cavity has been published in Frontiers in Oncology. Researchers show that structures inside the cells change as the disease progresses from benign to malignant, helping the cells to grow in an otherwise hostile environment of low nutrients and oxygen.
DURHAM, N.C. - Glioblastoma brain tumors are especially perplexing. Inevitably lethal, the tumors occasionally respond to new immunotherapies after they've grown back, enabling up to 20% of patients to live well beyond predicted survival times.
What causes this effect has long been the pursuit of researchers hoping to harness immunotherapies to extend more lives.
The ability of our skin to protect us from chemicals is something we inherit. Some people are less well-protected which could imply an increased risk of being afflicted by skin disease or cancer. A new study from Karolinska Institutet in Sweden that has been published in Environmental Health Perspectives shows how the rate of uptake of common chemicals is faster in people with a genetically weakened skin barrier.
ATLANTA - JANUARY 12, 2021 - Overall cancer death rates in the United States dropped continuously from 1991 through 2018 for a total decrease of 31%, including a 2.4% decline from 2017 to 2018. The news comes from the American Cancer Society's annual Cancer Statistics, 2021 article, appearing in CA: A Cancer Journal for Clinicians, and its consumer version, Cancer Facts & Figures 2021. This year marks the American Cancer Society's 70th anniversary of reporting this data to inform the nation's fight against cancer.
WASHINGTON--The Endocrine Society is calling on policymakers to include government negotiation as part of an overall strategy to reduce insulin prices in its updated position statement published today in The Journal of Clinical Endocrinology & Metabolism.
What The Study Did: National register data from Denmark were used to examine if people with autism spectrum disorder (ASD) have higher rates of suicide attempts and suicide compared to those without ASD and to identify potential risk factors.

BOSTON -- For women hoping to achieve a pregnancy using freshly retrieved donor eggs, a new retrospective study led by researchers from Brigham and Women's Hospital may provide important insight. Brigham senior author Janis H. Fox, MD, had observed that when freshly retrieved donor eggs were used, pregnancy rates were higher for fresh compared to frozen embryo transfers.
To properly monitor and help curb the spread of COVID-19, several millions of diagnostic tests are required daily in just the United States alone. There is still a widespread lack of COVID-19 testing in the U.S. and many of the clinical diagnostics protocols require extensive human labor and materials that could face supply shortages and present biosafety concerns.
For other measures, however, the behaviour of the generations differs: "Of those under 40 years of age, 18 percent say they have food delivered more frequently", says BfR-President Professor Dr. Dr. Andreas Hensel. "In the age group 60 years and older, on the other hand, only seven percent make use of such offers."
In patients with anorexia, it could remain at the same level as before the start of the illness. The researchers led by Professor Martin Diers recommend a combination of cognitive behavioural therapy and the use of virtual reality to correct the distorted body schema. The study is published in the International Journal of Eating Disorders on 20 December 2020.

In a major register-based study, scientists at University of Gothenburg, Sweden, have now demonstrated a connection between inferior physical fitness in young adults and elevated risk of the autoimmune disease psoriasis. For the male recruits to compulsory military training who were rated as the least fit, the risk of developing psoriasis later was 35 percent higher than for the fittest.
