Human skin wound dressings to treat cutaneous ulcers

Researchers at Université Laval have developed biomaterial-free biological wound dressings made from human skin grown in vitro. These dressings successfully treated venous ulcers in patients who had been chronically suffering from such wounds, with an average healing time of seven weeks.

Ultrasound patch heals venous ulcers in human trial

A new ultrasound patch has been shown to significantly accelerate healing in patients with venous ulcers, a type of chronic wound that affects millions. The patch, developed by researchers at Drexel University, delivers low-frequency ultrasound directly to wounds and was found to reduce wound size in just four weeks.

Studies of newly diagnosed prostate cancer patients reveal that older, sicker men are unlikely to benefit from aggressive therapy. Researchers found that those aged 61-74 and over 75 with multiple health issues face high risks of mortality from non-prostate causes, suggesting a shift towards more conservative treatment approaches.

Researchers found that mycolactone, a lipid toxin from Mycobacterium ulcerans, causes cytoskeletal dysregulation by activating the protein N-WASP. This led to defects in cell adhesion and migration, impairing skin integrity. The study suggests using N-WASP inhibitors as potential treatments for Buruli ulcers.

Cytoskeletal dysregulation underlies Buruli ulcer formation

Researchers discovered that mycolactone, a lipid toxin produced by Mycobacterium ulcerans, disrupts the cellular skeleton through N-WASP activation. This dysregulation impairs skin integrity and cell adhesion, leading to Buruli ulcers. Blocking N-WASP activity with wiskostatin may provide a new treatment approach.

UCLA-led study finds direct correlation between hospital bedsores, patient mortality

A new clinical study by UCLA researchers found a direct correlation between pressure ulcers, or bedsores, and patient mortality, as well as longer hospital stays and readmissions. The study tracked over 51,000 Medicare beneficiaries and found that seniors with bedsores were more likely to die during their hospital stay.

Gastric feeding tubes may raise pressure ulcer risk

A new study published in Archives of Internal Medicine reports that gastric feeding tubes may not prevent but rather increase the risk of pressure ulcers in people with advanced dementia. The analysis of thousands of nursing home patients found that those with a feeding tube were 2.27 times more likely to develop a stage II ulcer, and ...

Bacteria associated with stomach ulcers not detected in enlarged adenoids in children

A study published in Archives of Otolaryngology - Head & Neck Surgery found no evidence of Helicobacter pylori bacteria in enlarged adenoids of children. However, Candidatus Wolinella africanus was detected in one hyperplastic adenoid sample, suggesting occasional reflux episodes may contribute to the disease's pathophysiology.

Childhood physical abuse linked to peptic ulcers

Researchers at the University of Toronto found a strong association between childhood physical abuse and peptic ulcers in adulthood. The study, which analyzed data from over 13,000 Canadians, showed that victims of childhood abuse were 68% more likely to develop peptic ulcers.

Aged female patients taking low-dose aspirin should be paid special attention

Researchers identified age greater than 70 years as a significant risk factor for peptic ulcer in female patients taking low-dose aspirin. The study suggests a future strategy for prevention of LDA-associated gastroduodenal mucosal injury. A history of peptic ulcer was also found to be the risk factor common to both sexes.

Can EP4 agonist alleviate gastric lesions?

A research team investigated a highly-selective EP4 agonist for treatment of gastric ulcers in mice. The EP4 agonist reduced acute hemorrhagic damage, promoted mucous epithelial regeneration, and accelerated ulcer healing. In vitro, it protected human gastric mucous cells from indomethacin-induced apoptosis.
