Non-destructive image sensor goes beyond bulkiness

Researchers at Chuo University developed a non-destructive image sensor with a freely coatable and paintable design for functional photo-thermal modules. The new design enables the full utilization of photo-thermoelectric (PTE) sensors, overcoming trade-off trends between photo-absorptance values and Seebeck coefficients.

The U-shaped relationship between admission peripheral oxygen saturation and all-cause hospital mortality in acute exacerbation of chronic obstructive pulmonary disease: a retrospective analysis using the MIMIC III database

A U-shaped relationship between admission peripheral oxygen saturation and all-cause hospital mortality was observed in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD). The lowest mortality rate occurred at an SpO2 of 89.5%, indicating that lower oxygen levels are associated with increased risk.

DNA origami suggests route to reusable, multifunctional biosensors

Researchers at Caltech developed a DNA origami-based approach to create reusable, multifunctional biosensors for quickly detecting proteins in bodily fluids. The system uses a lilypad-like structure with short DNA strands to bind to molecules of interest, allowing for the detection of larger molecules such as large proteins.

Antidepressants linked to faster cognitive decline in dementia

A new observational study suggests that antidepressants can accelerate cognitive decline in people with dementia, while certain medications appear to be less harmful. Researchers analyzed data from 18,740 patients and found that selective serotonin reuptake inhibitors (SSRIs) were associated with the fastest cognitive decline.

Novel cigarette pricing policy linked to decrease in sales in California city

A new study found that an Oakland law requiring cigarette prices to increase to a minimum of $8 per pack led to a 15-percent decrease in cigarette sales and a 25-percent decrease in lower-priced cigarettes. The policy may be particularly effective at curbing tobacco initiation among low-income individuals and youth.

Bioprocessing method yields high-value products alongside biofuels

Researchers developed a sustainable process to recover valuable products from oilcane bagasse, generating multiple product streams. The process recovers anthocyanins and vegetative lipids for natural colorants and biofuel production, making the process more cost-effective and sustainable.

Childhood trauma and neighborhood disorder impact mental health of injured black men

A new study published in Journal of Urban Health reveals that childhood trauma and perceived neighborhood disorder significantly impact the mental health of Black men in Philadelphia following serious traumatic injuries. The study highlights the critical role of social and environmental factors in post-injury recovery.

GLP-1RAs may offer modest antidepressant effects compared to DPP4is but not SGLT-2is

A study found that GLP-1RAs may have a modest effect on depression risk compared to DPP4is, but not SGLT-2is in older adults with diabetes. Researchers used Medicare claims data from 2013 to 2020 and found slightly higher HgbA1c levels in MA beneficiaries, suggesting possible differences in disease management.

Performance-based reimbursement increases administrative burden and moral distress, lowers perceived quality of care

A longitudinal study of primary care physicians found that performance-based reimbursement increases illegitimate work tasks, moral distress, and lowers perceived individual and organizational quality of care. The study suggests that reducing irrelevant tasks could support physician well-being and healthcare delivery.

Mount Sinai-led research team identifies underlying mechanisms of age-related dysfunction in glands crucial to eye function

A Mount Sinai-led research team has identified stem cell populations and mechanisms underlying age-related degeneration in meibomian glands, which secrete lipid-rich meibum to prevent tear evaporation. The findings suggest that targeting Hh and EGFR signaling could be a potential therapeutic option for evaporative dry eye disease.

Empathic disequilibrium changes the way we think about empathy and could be a powerful diagnostic and treatment tool for autism, schizophrenia, and other clinical conditions

Researchers found that empathic disequilibrium, an imbalance between cognitive and emotional empathy, better explains symptoms in various clinical conditions. Prof. Florina Uzefovsky's work suggests this concept can be a powerful diagnostic and treatment tool for autism, schizophrenia, and other disorders.
