If Chicago feels like San Francisco this week, blame the Polar Vortex. The unusually cold winter means Lake Michigan is still pretty chilly, so as humid summery air hits the lake it turns anything along the lakefront into an EDM concert.

If Chicago feels like San Francisco this week, blame the Polar Vortex. The unusually cold winter means Lake Michigan is still pretty chilly, so as humid, summery air hits the lake it makes everything along the lakefront look like a dance club.

This week’s rundown of recent research publications of note from University of Chicago scientists and physicians:

Sleep behavior and unemployment conditions, including Diane Lauderdale, PhD — Economics & Human Biology

From the abstract: “Recent research has reported that habitually short sleep duration is a risk factor for declining health, including increased risk of obesity, diabetes and coronary heart disease. In this study we investigate whether macroeconomic conditions are associated with variation in mean sleep time in the United States, and if so, whether the effect is procyclical or countercyclical … Despite a national poll in 2009 that found one-third of Americans reporting losing sleep over the economy, we do not find that higher state unemployment is associated with more sleeplessness. Instead, we find that higher state unemployment is associated with less frequent time use described as “sleeplessness.”

Magnetic gastrointestinal anastomosis in pediatric patients, Mario Zaritzky, MD, lead author — Journal of Pediatric Surgery

From the abstract: “Patients with GI obstruction, stenosis, or atresia were treated with image-guided and/or endoscopically placed discoid magnet pairs or catheter-based bullet-shaped magnet pairs. Anastomosis was achieved in 7 days in an 11-year-old with gastric outlet obstruction due to metastatic colon cancer. Anastomosis was achieved in 8 and 10 days in 2 patients (age 2.0 years and 3.4 years) who had rectocolonic stenosis. Re-anastomosis was achieved in an average of 6 days (range 3 to 7 days) in 5 patients (age 6 months to 5.9 years) with severe recurrent postsurgical esophageal stenosis refractory to dilatation. Primary esophageal anastomosis was achieved in an average of 4.2 days (range 3 to 6 days) in 9 patients with esophageal atresia (Type A or Type C surgically converted to Type A) with a gap length of 4 cm or less … Minimally invasive magnet placement was feasible and achieved anastomosis in all patients.”

Type 1 Diabetes and Celiac Disease: Clinical Overlap and New Insights into Disease Pathogenesis, Aaron Cohn, MD, Anthony M. Sofia, MD, Sonia S. Kupfer, MD — Current Diabetes Reports

From the abstract: “Type 1 diabetes (T1D) and celiac disease (CD) are autoimmune diseases with clinical and pathogenic overlap. The mean prevalence of CD in patients with T1D is about 8 %. Classic intestinal symptoms of CD may not be present in T1D leading to the recommendation for active case finding in this higher risk group … A strict gluten free diet is recommended, although this can pose challenges for T1D patients who already have dietary restrictions. In aggregate, it appears as if the gluten free diet may help T1D management. T1D and CD have overlapping genetic and environmental risk factors.”
