Research led by Naval Medical University’s Changzheng Hospital in China reports that an off-the-shelf cell therapy built from induced pluripotent stem cells (iPSCs) loosened life-limiting skin and organ scarring in a woman with systemic sclerosis.

Systemic sclerosis progressively suffocates tissue through immune misfires, collapsed micro-vessels, and runaway collagen conditions that resist standard immunosuppressants, biologics, and anti-fibrotic drugs while driving a 40% 10-year mortality.

Cell-based approaches such as hematopoietic-stem-cell transplants and CAR-T therapies have shown promise but carry high toxicity or labor-intensive custom manufacturing, leaving clinicians and patients in search of safer, more accessible tools.

Helicobacter pylori (H. pylo ri) infection is an established cause of gastric cancer. Although H. pylo ri eradication is suggested to decrease gastric cancer risk, this has not been fully investigated in general populations. This analysis included 48,530 Japanese men and women aged 40–74 years from four cohort studies. At baseline, the participants provided a self-reported eradication history and serum anti–H. pylo ri IgG titers and the results of a pepsinogen (PG) test. We examined the association between eradication history and gastric cancer risk considering H. pylo ri positivity and PG testing using Cox proportional hazards regression models. From 2010 to 2,018,649 gastric cancer cases were diagnosed. Compared with those who were negative for both H. pylo ri and PG test as a reference, gastric cancer risk was 5.89 times higher (95%CI: 4.41–7.87) in those who were H. pylo ri-positive and/or PG test-positive and with no eradication at baseline. Gastric cancer risk among those who underwent eradication before baseline decreased after a temporal increase in risk following eradication (baseline to 1y: HR 1.74, 95%CI 1.18–2.57; 1y to Ono, A., Tanaka, S., Sawada, N. et al.

Researchers at Stanford have developed a new technology for removing blood clots that is more than twice as effective as current techniques. It could significantly improve success rates in treating strokes, heart attacks, pulmonary embolisms, and other clot-related diseases.

We have now learned why wounds in our mouth don’t scar, which could lead to treatments that prevent such blemishes on the skin
