Tuberculosis: New insights into the pathogen
Researchers at the University of Würzburg and the Spanish Cancer Research Centre have gained new insights into the pathogen that causes tuberculosis. Tuberculosis is a highly contagious infectious disease that is typically spread through aerosols and mainly affects the lungs. According to the World Health Organization (WHO), an estimated 1.7 million people die from such an infection worldwide every year.

Fresh insights could lead to new treatments for liver disease
The fight against liver disease could be helped by the discovery of cells that cause liver scarring. Scientists have identified new sub-types of cells that, when they interact, accelerate the scarring process in diseased livers. Experts hope that by understanding more how these cells behave, new treatments can be developed more quickly for liver diseases.

Badger culling drives animals further afield increasing risk of TB spread
New research reveals survivors of culls cover greater areas potentially increasing the risk of TB transmission to cattle. A study led by researchers at international conservation charity ZSL (Zoological Society of London) and Imperial College London has found that culling drives badgers to roam 61% further afield - helping to explain why the practice, intended to reduce bovine TB transmission, can sometimes exacerbate the problem instead.

In rats suggests special occasion drinking during pregnancy may cause harm
Research from The University of Queensland suggests even small amounts of alcohol consumed during pregnancy could cause insulin-resistance in male rat offspring. The study mimicked 'special occasion drinking', such as a family barbeque or birthday party, where a pregnant woman might be encouraged to have one or two alcoholic drinks.

The cholera bacterium can steal up to 150 genes in one go
The cholera bacterium can steal up to 150 genes in one go
EPFL scientists have discovered that predatory bacteria like the cholera pathogen can steal up to 150 genes in one go from their neighbors. The study sheds light on one of the most fundamental mechanisms of horizontal gene transfer. In 2015, EPFL researchers led by Melanie Blokesch published a seminal paper in Science showing that the bacterium responsible for cholera, Vibrio cholerae , uses a spring-loaded spear to literally stab neighboring bacteria and steal their DNA.

On Your Medicine’s Secret Service
Whether a wound heals well under a dressing cannot be seen from the outside. Empa researchers are now enabling a view through the bandage à la James Bond. The refined application of terahertz radiation could promote the analysis of multi-layered tissues for medical purposes and be used for wound treatment or the diagnostics of blood vessel plaques.

UNAIDS HIV targets will be missed among gay men in Africa
UNAIDS HIV targets will be missed among gay men in Africa
Despite improvements in HIV testing among men who have sex with men (MSM) in Africa, many are missing out on HIV treatment. This is the finding of research, led by Imperial College London , which analysed data from 75 independent studies involving 44,993 MSM across 28 African countries, between 2004 and 2018.

Secrets of lung cancer spread found in patients' blood and biopsies
Secrets of lung cancer spread found in patients’ blood and biopsies
Early signs that a patient's lung cancer may spread and become untreatable can be picked up in samples of their blood and tumour, according to a trio of papers co-led by UCL. The three studies, published , are all part of Cancer Research UK's £14million TRACERx project, which aims to understand how lung cancer cells change over time and become resistant to treatment.

Violence linked to loneliness, hypervigilance and chronic health problems
Exposure to violence can negatively impact a person's physical and psychosocial health, according to two new studies co-authored by University of Chicago scholars. The studies, co-authored by social epidemiologist  Elizabeth L. Tung , were based on in-person surveys of more than 500 adults living in Chicago neighborhoods with high rates of violent crime, and in predominantly racial and ethnic minority groups.

To fight effects of sleep deprivation, reach for healthy snacks
In a study of 245 Stanford physicians, researchers found that a better diet is associated with reduced side effects of sleep deprivation. Nutrition scientist   Maryam Hamidi , PhD, conducted research recently which required her to repeatedly stay awake from 8 a.m. until 5 a.m. the next day.

Patient-aligned care reduces unwanted medications, tests for older adults
An emerging approach to health care that focuses decision-making on older patients' health goals and care preferences can reduce unwanted and unhelpful treatment, such as medications and diagnostic tests, say Yale researchers. It can also lessen treatment burden, according to their new study, published in JAMA Internal Medicine.

California program is a good step toward coordinating care for high-needs patients
An evaluation by UCLA researchers has found that a California program launched in 2016 has been a positive step toward providing better-coordinated health care for people insured by Medicaid. Initial findings from the ongoing analysis were published today by the UCLA Center for Health Policy Research.

Clues from DNA could help predict growth of prostate cancer
FINDINGS Researchers from the UCLA Jonsson Comprehensive Cancer Center and other institutions in the U.S., Canada, the United Kingdom and Singapore, have identified 1,178 biomarkers in men's genomes — the complete set of genetic material inherited from one's parents — that predict how an individual person's prostate cancer will grow.

The Screw That Dissolves
The Screw That Dissolves
Where bones fracture, surgeons often have to join the fragments with implants. Magnesium orthopaedic screws, which over time dissolve in the body, spare patients another operation after healing is completed and reduce the risk of infection. What happens inside the body during this process, though, is still largely unknown.

Health disparities, strong social support among state's LGBTQ community
Health disparities, strong social support among state’s LGBTQ community
LGBTQ individuals in Washington state have higher rates of disability and poorer mental health than their heterosexual counterparts, according to a study released Oct. 4 by the University of Washington. The results of the Washington State Equity and Diversity Project show specific disparities in the health of LGBTQ adults aged 18 and older.

Scientists uncover genetic similarities among species that use sound to navigate
Evolutionary adaptations like echolocation that are shared by unrelated species arose in part due to identical, independently acquired genetic changes, according to a new Stanford study of whole genome sequences. Insect-eating bats navigate effortlessly in the dark and dolphins and killer whales gobble up prey in murky waters thanks in part to specific changes in a set of 18 genes involved in the development of the cochlear ganglion - a group of nerves that transmit sound from the ear to the brain, according to a study by researchers at Stanford University.

Early menopause predictor of heart disease
Women who reach menopause before the age of 50 have an increased risk of cardiovascular disease, according to researchers from The University of Queensland. School of Public Health senior author Professor Gita Mishra said the results showed early menopause puts women at greater risk of suffering a non-fatal cardiac event like heart attack, angina or stroke.

Fat cells are used to deliver drug that suppresses tumor growth in mice
FINDINGS In a study with mice, researchers at the UCLA Jonsson Comprehensive Cancer Center have identified a new mechanism for delivering a drug that can help stop tumors from growing and keep cancer from recurring. The scientists found that they could reengineer adipocytes — fat cells that provide fatty acids with the energy needed for tumors to grow and spread — to reverse their role in tumor development and deliver cancer-fighting drugs directly to the area of the body immediately surrounding the tumor.
