Senior living environments: evidence-based lighting design strategies.

Objective: To review from an architectural lighting perspective the effects of indoor lighting on the health and well-being of people in senior living environments.

Background: The role of circadian rhythms in people with chronic disorders continues to be a focus of laboratory research and clinical trials. Beneficial, evidence-based indoor lighting design strategies are being considered for senior living environments, particularly for residents who have limited access to natural bright light.

Selection of electrical algorithms to treat obesity with intermittent vagal block using an implantable medical device.

Background: A laparoscopically implantable electrical device that intermittently blocks both vagi near the esophagogastric junction led to significant excess weight loss (EWL) in an initial clinical trial in obese patients. The study objective was to optimize therapy algorithms and determine the EWL achieved with a second-generation device at university hospitals in Australia, Norway, and Switzerland.

Methods: Data acquired during the initial clinical trial were analyzed and subsequently used to select alternative electrical algorithms.

Central corneal thickness in pediatric glaucoma.

Purpose: To compare the central corneal thickness (CCT) of children with and without glaucoma and to estimate the effect CCT may have on the intraocular pressure (IOP) assessment of children.

Patients And Methods: CCT and IOP measurements were performed in an unmasked fashion in 34 consecutive children with glaucoma and 28 consecutive children without glaucoma. Patients with corneal edema or extensive corneal scarring were excluded.

Tube occlusion from the external ostium after implantation of an aqueous shunt.

Two patients had undergone double-plate Molteno shunt implantation. Both patients required surgical revision, the first at 41 months and the second at 8 months postoperatively, because of a failure of previously functioning tube shunts caused by blockage of the external ostium and intraluminal invasion of the tube by fibrous tissue. At the time of surgical revision, fibrous tissue extended down the lumen of the tube, occluding its external ostium.
