Using Electronic Health Records to Identify the Daily Primary Provider During Hospitalization.

Objectives: Providers vary in their impact on clinical outcomes, but this is rarely accounted for in healthcare research. By failing to identify the provider responsible for a patient's care, investigators miss an opportunity to account for nonrandom variation in outcomes. Prior methods of identifying responsible providers have relied on manual chart review, which is time-consuming and expensive, or analysis of claims data, which has been demonstrated to be inaccurate.

Biomechanics and ontogeny of gliding in wingless stick insect nymphs (Extatosoma tiaratum).

Many wingless arboreal arthropods can glide back to tree trunks following free falls. However, little is known about the behaviors and aerodynamics underlying such aerial performance, and how this may be influenced by body size. Here, we studied gliding performance by nymphs of the stick insect Extatosoma tiaratum, focusing on the dynamics of J-shaped trajectories and how gliding capability changes during ontogeny.

Visual hallucinations in psychosis: What do people actually see?

Background: One in three people with psychosis experience visions. However, little is known about what people see, and current treatments have limited benefits.

Objectives: To improve the understanding and treatment of visions, this study explored the phenomenology of visions in people with psychosis.

Hair-sparing approach versus traditional hair clipping for cerebral spinal fluid shunt procedures: a retrospective comparative study.

Objective: Cerebral spinal fluid (CSF) diversion methods, including ventriculoperitoneal (VP) shunts, are the standard treatment for hydrocephalus. Hair clipping (HC) has been a routine neurosurgical practice of the great majority of neurosurgeons, due to the perception that this will either decrease the risk of shunt infection or allow for a faster, unimpeded opening and closing of the skin. The benefits of not cutting or clipping hair in terms of normalizing appearance and self-esteem are obvious.
