Osaka Metropolitan University researchers conducted a large-scale clinical study to identify long-term rebleeding rates and predictors of rebleeding after capsule endoscopy (CE) in patients with obscure gastrointestinal bleeding (OGIB). The results revealed that the overall cumulative rebleeding rate in the five years after CE was as high as 41.7%, and they also suggested the need for particularly careful follow-up in patients with liver cirrhosis, those taking anticoagulants, or those with previous massive bleeding. The study offers an important finding in considering the long-term follow-up regarding OGIB, and might contribute to future clinical guidelines for OGIB treatment.

Osaka Metropolitan University scientists revealed quadriceps tendon-patellar bone (QTB) grafts as a more suitable option than bone-patellar tendon-bone (BPTB) grafts for anterior cruciate ligament (ACL) reconstruction. Examinations in human cadavers and ACL reconstruction patients showed that the QTB graft is more similar to the ACL at the femoral insertion site than the BPTB graft. The difference between graft bending angle (GBA) and an angle corresponding to GBA showed that the QTB graft bends less than the BPTB graft, suggesting a lower risk of excessive stress on the insertion site and thereby a lower probability of ACL reconstruction failures. These findings contribute to potential improvement in ACL reconstruction for knee injury patients.

Scientists at Duke-NUS Medical School, Singapore, have found that elevated blood levels of an amino acid called homocysteine correlate strongly with the severity of an advanced form of non-alcoholic fatty liver disease. They also found vitamin B12 and folic acid could potentially prevent and/or delay disease progression.

Researchers have discovered that vitamin K acts as a powerful antioxidant. It can inhibit ferroptosis, a type of cell death associated with Alzheimer’s disease and organ damage, by trapping lipid radicals. Furthermore, the team identified the long-sought-after vitamin K-reducing enzyme, the identity of which remained unknown for more than half a century.

A team of researchers led by Osaka University has found that mutations in the calcium channel protein RyR1 that confer susceptibility to malignant hyperthermia make the protein hypersensitive to heat, which triggers excessive calcium release from the endoplasmic reticulum. Clarifying the mechanism by which calcium release is accelerated at an elevated temperature in patients with malignant hyperthermia may also provide important insight into how exertional heat stroke occurs under extreme environmental conditions.

A research group led by Associate Professor Kazuki Uemura of the Graduate School of Rehabilitation Science, Osaka Metropolitan University conducted a cross-sectional study, using GPS and accelerometers, of 133 elderly people (aged 65 or older) in Toyama Prefecture to investigate their out-of-home behavior and amounts of physical activity during 14 days. The results demonstrated that the amounts of physical activity among the participants were more strongly influenced by the number of visited places (nodes) than by out-of-home time. This suggests that diversity, not just duration, of out-of-home behavior may be important when encouraging the elderly to go out to extend their life expectancy.

Osaka University researchers designed a silicon-based agent that successfully generated hydrogen continuously in the mouse gastrointestinal tract in an ulcerative colitis (UC) model. The hydrogen served as an antioxidant that could eliminate the reactive oxygen species shown to induce the chronic inflammation responsible for the damage and symptoms caused by UC. Mice given the agent had reduced hemorrhage, inflammation, and hyperexcitability in the brain area associated with visceral pain and discomfort. These results may help with the development of a novel treatment for UC.

Cultured human skeletal muscle cells infused with serum from hibernating bears exhibited “muscle gain” confirming that these creatures’ ability to avoid muscular damage despite months of inactivity is in their blood.

A research group led by Dr. Soichi Sano, a specially appointed lecturer in the Department of Cardiovascular Medicine, Graduate School of Medicine, Osaka Metropolitan University, revealed that men with hematopoietic mosaic loss of Y chromosome (mLOY) — meaning men with an increase, in the blood, of cells that have lost the male sex chromosome — have a worse prognosis for heart failure due to fibrosis progression in the heart. Furthermore, in experiments using mice, which, like humans, have an increased mortality rate with age, they found that the presence of mLOY causes overproduction of fibrosis-promoting substances, which leads to the progression of cardiac fibrosis, a mechanism directly related to a worse prognosis for heart failure.

Fresh vegetables in vinegar, similar to pickles, are a perfect side dish, commonly served with Japanese cooking. One traditional side dish called sunomono, a cool cucumber or seaweed salad, provided a unique opportunity as a source of dietary vinegar. This new observational study from Osaka Metropolitan University noted that men over 40 who eat sunomono at least once a month were significantly more likely to be in lower blood pressure categories.

Researchers from Osaka University have described a case of clinically typical Parkinson’s disease with unusual changes in the brain. As well as the expected findings of cell loss and inflammation in disease-related brain regions, there were accumulations of the protein TDP-43 instead of the usual alpha-synuclein inclusions. This report suggests that TDP-43 accumulation can cause Parkinson’s disease-like symptoms and brain changes, which may be important for developing new treatments for this currently uncurable disease.

Researchers from Osaka University have found that infection with SARS-CoV-2 activates the expression of IRF1, a key regulator of insulin/IGF signaling in multiple tissues, leading to disruption of blood sugar metabolism and, in some cases, new onset of diabetes. Treating infected cells with hormonal factors that decreased IRF1 expression enhanced insulin/IGF signaling, suggesting that this approach could be used to mitigate some of the more severe side effects of COVID-19 in the future.
