Article Synopsis
- A global outbreak of clade II mpox has been primarily affecting gay, bisexual, and other men who have sex with men (MSM) since May 2022, with limited understanding of transmission routes.
- A study analyzed 457 case-patients and 1,030 control patients (aged 18-49) to estimate the odds of mpox transmission based on different types of close contact; results showed that those engaging in condomless receptive anal sex had a 5.4 times higher odds of contracting mpox.
- Despite the effectiveness of the mpox vaccine, vaccination rates are low, highlighting the need for a comprehensive prevention strategy that includes vaccination promotion and safer sex practices.
Article Synopsis
- Racial minorities, particularly non-Hispanic Blacks and Hispanics, are more likely to face severe diabetic foot complications and a heightened risk of lower limb amputation.
- The study analyzed 597 patients from various clinics to investigate if race affects referral rates to specialists for diabetic foot ulcers (DFUs) and the severity of the ulcers at first presentation.
- Findings indicated no significant differences in referral rates or ulcer severity based on race, though those presenting in the emergency department had worse conditions, which were linked to higher amputation rates.
Article Synopsis
- * Current detection methods for these changes are limited by the need for labeling and high costs, whereas the nanopore approach can capture real-time changes in nucleic acid structure.
- * The study developed a new, label-free nanopore system that tracks conformational transitions in nucleic acids with millisecond precision, enabling the detection of binding events for ligands like dopamine and serotonin, which has implications for biosensing and drug discovery.
Article Synopsis
- Over 30,000 monkeypox cases were reported in the U.S. by March 31, 2023, with the outbreak mainly affecting gay, bisexual, and transgender individuals.
- The FDA approved the JYNNEOS vaccine in 2019 for smallpox and monkeypox prevention, and in August 2022, allowed a new injection method to increase vaccine access.
- A study showed that JYNNEOS vaccine effectiveness was 75.2% for partial vaccination and 85.9% for full vaccination among men who have sex with men and transgender individuals aged 18-49.
Problem: American Indian/Alaska Native (AI/AN) populations are facing multiple health crises, including limited access to care, high rates of chronic disease, and early mortality that is far worse than other underrepresented minorities in the United States. According to the Association of American Indian Physicians, AI/AN people represent 2.0% of the U.
View Article and Find Full Text PDFWe study the reproducibility of quantitative imaging features that are used to describe tumor shape, size, and texture from computed tomography (CT) scans of non-small cell lung cancer (NSCLC). CT images are dependent on various scanning factors. We focus on characterizing image features that are reproducible in the presence of variations due to patient factors and segmentation methods.
