Children use nasogastric tubes (NGTs) to ensure optimum nutrition and medication delivery when oral feeding fails or when they experience faltering growth. Although this method is less invasive, children may experience complications associated with NGTs. There is a gap in the literature regarding the types and prevention of complications of NGTs in the pediatric population at home.

Ecological variation and anthropogenic landscape modification have had key roles in the diversification and extinction of mammals in Madagascar. Lemurs represent a radiation with more than 100 species, constituting roughly one-fifth of the primate order. Almost all species of lemurs are threatened with extinction, but little is known about their genetic diversity and demographic history.

Studying biological ageing in animal models can circumvent some of the confounds exhibited by studies of human ageing. Ageing research in non-human primates has provided invaluable insights into human lifespan and healthspan. Yet data on patterns of ageing from wild primates remain relatively scarce, centred around a few populations of catarrhine species.

Children with medical complexity have medical fragility, chronic disease, technology dependence, and high healthcare use. Their transition to adult health care at age 18 involves medical and social elements and follows no standardized process. Our goal was to improve transition readiness in children with medical complexity using a transition intervention within a Complex Care program.

Background And Objectives: Care plans summarize a child with medical complexity's (CMC) medical history and ongoing care needs. Often, the health care team controls the care plan content, limiting caregivers' ability to edit the document in real time and potentially compromising accuracy and utility. With this study, we aimed to provide caregivers of CMC with online access and shared editing control of their child's care plan and to explore the experiences of caregivers and care team members (CTMs) after using an online collaborative care plan (OCCP).

Despite decades of field study, very little is known about the molecular ecology of gibbons, particularly as it relates to their ability to disperse across degraded and fragmentary landscapes. The critically endangered western black crested gibbon (Nomascus concolor) has been reduced to a small, fragmented population with about 1300 individuals. In the largest population genetic study of free-ranging gibbons to date, we sampled 47 of these gibbons from 13 sites in China and generated 15 polymorphic autosomal microsatellite markers.
