Pre-flight body weight effects on urinary calcium excretion in space

Semran B. Thamer, Mirjana Stevanovic, Jay C. Buckey

Microgravity-induced bone loss increases urinary calcium excretion which increases kidney stone formation risk. Not all individuals show the same degree of increase in urinary calcium and some pre-flight characteristics may help identify individuals who may benefit from in-flight monitoring. In weightlessness the …

The Relationship Between the Timing of Knee Osteoarthritis Diagnoses and Arthroscopic Partial Meniscectomy

Semran B. Thamer, Corey T. Resnick, Paul M. Werth, David S. Jevsevar

BACKGROUND: There is ongoing debate regarding the efficacy of arthroscopic partial meniscectomy (APM) for meniscus tears in patients with knee osteoarthritis (OA). Some insurance payers will not authorize APM in patients with knee OA. The purpose of this study was to assess …

Bone loss and kidney stone risk in weightlessness

Jay C. Buckey, Semran B. Thamer, Mimi Lan

PURPOSE OF REVIEW: Weightlessness increases both bone loss and kidney stone formation risk. The large interior volume of the International Space Station (ISS) has allowed for a mix of exercise devices to help maintain the skeleton. But space exploration is changing. Long …

First Void Urinary Calcium for Tracking Bone Loss and Kidney Stone Risk in Space

Semran B. Thamer, Jay C. Buckey

INTRODUCTION: Microgravity exposure unloads the skeleton. This increases urinary calcium excretion, which reflects both increased bone loss and kidney stone formation risk. We studied the probability that first morning void (FMV) urinary calcium (Uca) measurements would capture the highest Uca concentration in …

Sleep Apnea and Postoperative Medical Complications and Health Care Expenditures Following Open Reduction and Internal Fixation of Bimalleolar Ankle Fractures

Semran B. Thamer, Aaron W. Lam, Ivan J. Golub, Matthew L. Magruder et autres

Introduction Sleep Apnea (SA) is a common sleep disorder that increases postoperative morbidity. There is limited research on how SA influences outcomes following operative fixation of ankle fractures. Therefore, the aim of this study was to determine whether patients who undergo surgical …
