Teen pregnancy and risk of premature mortality

JAMA Network Open

2024-03-14
(Press-News.org) About The Study: Teen pregnancy was associated with future premature mortality in this study of 2.2 million female teenagers. It should be assessed whether supports for female teenagers who experience a pregnancy can enhance the prevention of subsequent premature mortality in young and middle adulthood. 

Authors: Joel G. Ray, M.D., M.Sc., of the University of Toronto, is the corresponding author.

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 ...

Revolutionary nanoparticle therapy offers new hope for burn victims

Revolutionary nanoparticle therapy offers new hope for burn victims
2024-03-14
A research has developed a new nanoparticle treatment that significantly improves outcomes for severe burn-induced intestinal barrier disruption. The study introduces Luminol-conjugated cyclodextrin (LCD) nanoparticles, offering a promising therapeutic intervention for one of the most critical complications following severe burn injuries. Severe burns can cause critical issues, including deep tissue damage and increased risk of fatal conditions like sepsis and organ failure. A major concern is the disruption of the intestinal barrier, leading to inflammation and systemic ...

New study unveiled burn injury disrupts gut microbiome and weakens intestinal mucus barrier

New study unveiled burn injury disrupts gut microbiome and weakens intestinal mucus barrier
2024-03-14
The gut microbiota, a complex ecosystem within the human intestinal tract, is increasingly recognized for its vital role in human health and disease. Notably, its relationship with intestinal damage due to burns has been underexplored. New study has unveiled the pivotal role of gut microbiota in the synthesis and degradation of intestinal mucus following burn injuries in mice. Utilizing advanced 16S rRNA and metagenomic sequencing techniques, researchers have identified significant changes in gut microbiota composition and its impact on the intestinal mucus barrier. On a study ...

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 ...

Healing diabetes wounds with a new superhero: stem cell magic

Healing diabetes wounds with a new superhero: stem cell magic
2024-03-14
Researchers unveiled a novel therapy for diabetic wound healing. This research highlights the use of exosomal miR-4645-5p from hypoxic bone marrow mesenchymal stem cells (BMSCs) to significantly enhance wound healing by promoting keratinocyte autophagy. Diabetic wounds, often challenging to treat and prone to complications, can severely impact patients' quality of life. Traditional treatments have struggled with issues like low survival rates of transplanted cells and potential for immune rejection. This research introduces a groundbreaking approach using stem cells' regenerative capabilities. On ...
