Mental health conditions in partners and adult children of stroke survivors

2024-03-14
About The Study: In this study of partners and adult children of stroke survivors, risks of several mental health conditions and self-harm or suicide were moderately higher compared with the general population and, to a lesser extent, partners and adult children of heart attack survivors. These findings highlight the potential consequences of stroke among family members, particularly partners, and its findings may possibly serve as a quantitative foundation for the development of future stroke rehabilitation services.  Authors: Nils Skajaa, Ph.D., of Aarhus University Hospital in Aarhus, Denmark, is the corresponding author.  To ...

New study - chimp moms play with their offspring through good times and bad

New study - chimp moms play with their offspring through good times and bad
2024-03-14
When it comes to nurturing their young, mother chimpanzees go the extra mile, according to a new study. Using 10 years of observational data on wild chimpanzees, researchers found that while adults often play, and young chimps play a lot, when food gets scarce, the adults put mutual play aside and focus on survival. But in the meantime, mother chimps continue to be their offspring’s primary playmate, tickling, chasing, playing ‘airplane’. That suggests the mother chimps take on an indispensable role ...

Tissue samples show the deep genetic and cellular impacts of smoking

2024-03-14
It’s no secret that smoking is extremely detrimental to health. Tobacco smoke contains thousands of chemicals, including carcinogens, increasing the risk of cancer, cardiovascular and respiratory diseases. A new study from the University of Chicago analyzed data from more than 900 samples of nine different human tissue types to understand just how deep the cellular and genetic damage from smoking goes. The research team generated epigenetic data to assess the effects of smoking on DNA methylation, or genetic locations where a handful ...

SickKids program provides integrated, trauma-informed care for pregnant and parenting adolescents

2024-03-14
The pregnancy and post-partum experience is stressful, but for pregnant adolescents the barriers to accessing supportive care can have fatal consequences.   A recent study from The Hospital for Sick Children (SickKids) identified that compared with those who had no teen pregnancy, teenagers in Ontario who experienced a pregnancy were at a 50 per cent higher risk of premature death before the age of 31. This risk was even higher for people who had two or more teen pregnancies and amongst those who were pregnant before 16 years of age.  Published in JAMA Network Open, the study also found that ...

Even cells know the importance of recycling

Even cells know the importance of recycling
2024-03-14
Researchers from Tokyo Medical and Dental University (TMDU) uncover the specific protein interactions needed for cells to break down and remove damaged mitochondria Tokyo, Japan – Autophagy is a process used by cells as a recycling system to transport and break down organelles and other cytosolic components, which become enveloped in a membrane called the autophagosome (Fig 1). When this involves the removal of damaged mitochondria, commonly called the “powerhouse” of the cell, it is known as mitophagy. In a recent article ...

Researchers may have found key to deprogram cells that lead to transplant rejection

Researchers may have found key to deprogram cells that lead to transplant rejection
2024-03-14
HOUSTON-(Mar. 14, 2024) – Houston Methodist researchers identified a troublesome subset of T-cells in transplant recipients that may be a more effective therapeutic target for preventing transplant rejection in patients.   Each day, 17 people die waiting for organ transplants, but getting a new organ doesn’t guarantee survival. Despite immunosuppressive medications, rejection of transplanted organs happens in up to 50% of patients, depending on the type of organ transplanted and the duration since the transplantation.   Wenhao Chen, Ph.D., associate professor of transplant immunology with the Houston Methodist Research ...

Bariatric surgery linked to heart health improvements in people with severe obesity

2024-03-14
WASHINGTON—Bariatric surgery may result in significant cardiometabolic improvements, particularly among younger, female, or white people and those without comorbidities, according to new research published in the Journal of the Endocrine Society. The United States has the highest obesity rates globally. In 2017-2018, about 40% of U.S. adults had obesity and 9% had severe obesity. The prevalence is particularly high among Black adults. Bariatric surgery is one method to help people with severe obesity lose a lot of weight and improve their health. “Our study highlights how bariatric surgery not only leads to significant weight loss but also substantially improves ...

Improving education and human security for vulnerable refugee children

Improving education and human security for vulnerable refugee children
2024-03-14
‘Access to education’ is recognized as a fundamental human right and is listed as one of the United Nations’ sustainable development goals to achieve by 2030. Quality education unlocks opportunities and gives individuals the freedom to make livelihood choices and shape their own destinies. However, an increasing number of refugee children are deprived of this fundamental right. According to the UNHCR, between 2010 and 2022, the number of child refugees doubled from 20.6 million to about 43.3 million.   An overwhelming majority of these refugees are displaced to neighboring countries that are short on resources and lack adequate educational infrastructure ...

2024-03-14
There is a growing emphasis for corporations to consider their impact on the environment, society, and its stakeholders. Broadly falling under environmental, social and governance or ESG, this involves practices such as using sustainably sourced materials, reducing carbon emissions, improving labor practices, fostering positive community relations, and promoting ethical corporate behavior, including efforts against anti-competitive practices and corruption.   The first mention of ESG appears in a 2004 UN report ...

Supercharging fuel cells with caffeine

Supercharging fuel cells with caffeine
2024-03-14
With global goals set on transitioning away from fossil fuels, fuel cells stand out as a promising carbon-free energy source. Comprising an anode and a cathode separated by an electrolyte, fuel cells convert the chemical energy of fuel directly into electricity. The anode receives the fuel, while an oxidant, typically oxygen from the air, is introduced at the cathode. In a hydrogen fuel cell, hydrogen undergoes oxidation at the anode, producing hydrogen ions and electrons. The ions move through the electrolyte to the cathode, and electrons flow through an external circuit, generating electricity. At the cathode, oxygen combines with the hydrogen ions ...

Poor neighborhoods linked to elevated dementia risk and faster brain aging

2024-03-14
DURHAM, NC – Living in a poorer neighborhood is linked to accelerated brain aging and increased dementia risk early in life, regardless of income level or education, a Duke University-led study finds. The study, which appears March 14 in Alzheimer's & Dementia: The Journal of the Alzheimer's Association, suggests that targeting disadvantaged neighborhoods for dementia prevention programs and encouraging clinicians to consider a patient’s address could help lower dementia risk. “If you want to prevent dementia, and you’re not asking someone ...

Dog-killing flatworm discovered in Southern California

Dog-killing flatworm discovered in Southern California
2024-03-14
UC Riverside scientists confirm, for the first time, that a potentially fatal dog parasite is present in a portion of the Colorado River that runs through California.  The parasite, Heterobilharzia americana, is a flatworm commonly referred to as liver fluke. Previously found almost exclusively in Texas and other Gulf Coast states, it has never been reported this far west. The worm can cause canine schistosomiasis, an illness that impacts the liver and intestines of dogs.  “Dogs can die from this infection, so we are hoping ...
