Severe neonatal hyperbilirubinaemia in European and Indian subcontinent descendent newborns: a retrospective cohort study.

Neonatal hyperbilirubinaemia is more common in Asian-descendent populations, but differences in disease severity are poorly reported. Our study aimed to compare neonatal hyperbilirubinaemia severity between European and Indian subcontinent descendent newborns. We conducted a single-centre retrospective cohort study including newborns admitted with unconjugated hyperbilirubinaemia (January 2016 to December 2021).

Qualitative insights on sexual health counselling from refugee youth in Bidi Bidi Refugee Settlement, Uganda: Advancing contextual considerations for brief sexuality-related communication in a humanitarian setting.

Characteristics of enabling healthcare environments to support brief sexuality-related communication (BSC) are understudied in humanitarian settings. We implemented a qualitative study with refugee youth aged 16-24 living in Bidi Bidi Refugee Settlement to understand the feasibility of implementing BSC in a humanitarian context. We examined feelings toward doctor's visits in general, including types of conversations youth engage in with healthcare providers, as well as comfort, safety, and willingness to talk with healthcare providers about sexual health.

Use of the transposition u-shaped palatal flap and polypropylene mesh to correct oronasal communication after resection of maxillary osteosarcoma in a dog.

Although less common in the axial skeleton, osteosarcoma, when present in the facial bones, can generally require invasive surgical procedures, which require large resections followed by reconstructions that can disfigure the patient and predispose them to physiological difficulties. We describe a technique used to correct oronasal communication that occurred after suture dehiscence from a left central hemimaxillectomy procedure in a female Rottweiler diagnosed with osteosarcoma. Clinical and radiographic findings are discussed, as well as the palatal mucosal flap surgical technique associated with the use of a synthetic polypropylene mesh.

Temporal change in minimum mortality temperature under changing climate: A multicountry multicommunity observational study spanning 1986-2015.

Background: The minimum mortality temperature (MMT) or MMT percentile (MMTP) is an indicator of population susceptibility to nonoptimum temperatures. MMT and MMTP change over time; however, the changing directions show region-wide heterogeneity. We examined the heterogeneity of temporal changes in MMT and MMTP across multiple communities and in multiple countries.
