Hip and waist circumference correlations with demographic factors and pain intensity in patients with chronic pain.

This study aimed to investigate how demographic factors such as race, age, sex and ethnicity can impact hip circumference (HC) and waist circumference (WC) in patients with chronic pain. We queried the NIH-sponsored All of Us database for patients with documented HC, WC and waist/hip ratio (WHR) data. This cross-sectional study categorized participants into four groups: total cohort, no chronic pain, mild/moderate chronic pain (numeric rating scale < 7) and severe chronic pain (numeric rating scale > 7).

Hospital teaching status associated with reduced inpatient mortality and perioperative complications in surgical neuro-oncology.

Purpose: Studies have demonstrated that higher surgical volumes correlate with improved neurosurgical outcomes yet none exist evaluating the effects of hospital teaching status on the surgical neuro-oncology patient. We present the first analysis comparing brain tumor surgery perioperative outcomes at academic and non-teaching centers.

Methods: Brain tumor surgeries in the Nationwide Inpatient Sample (NIS) from 1998 to 2014 were identified.
