Segmental Megaesophagus Secondary to Extraluminal Esophageal Stenosis Caused by Transitional Seventh Cervical Vertebra and Supernumerary Ribs in a Goat.

A 4-year-old Nigerian Dwarf wether presented for chronic regurgitation and cervical swelling of three years duration. Physical examination revealed a large ventral cervical mass. The goat made repeated attempts to swallow and regurgitate, but the mass did not change significantly in size.

Medical Student Confidence in Meeting Disability Competencies: Results of a national survey-based study.

People with disabilities have recently been declared a population at increased risk of health disparities, and research has cited a lack of physician training as a cause of that increased risk. Prior studies demonstrate that physicians lack confidence in caring for people with disabilities, but there is little research on disability competency among medical students. This study assessed medical students' confidence in six disability-related competencies and tested for associations between perceived confidence and students' personal demographics and institutional characteristics.

Environmental risk assessment of the surface sediments based on trace elements analysis from the largest freshwater lake in the southern slope of the Himalaya, Nepal.

Freshwater ecosystems, including high-altitude lakes, can be affected by trace metal pollution derived from a mix of natural sources and anthropogenic activities. These pollutants often collect in surface sediments, with notable concentrations in the deeper areas of lakes. To evaluate the environmental risk associated with metal contaminated sediment in Rara Lake, southern Himalaya, surface sediment samples were systematically collected in November 2018, with a subsequent specific emphasis on determinations of trace element concentrations.
