In Vivo Measurements Reveal Increased Nucleus Pulposus Lactate and Oxygen Concentrations in a Goat Model of Intervertebral Disc Degeneration

JOR Spine
Introduction Intervertebral disc degeneration is strongly implicated as a cause of low back pain. Although the precise pathophysiological mechanisms remain elusive, perturbations in nutrition that adversely impact the cellular microenvironment of the ...

L5 spondylolysis increases segmental mobility at the cranial adjacent level without altering intervertebral disc contact pressure

Frontiers in Bioengineering and Biotechnology
ObjectiveWhile lumbar spondylolysis has been biomechanically associated with subsequent spondylolisthesis and disc degeneration, its implications on cranial adjacent segments remain unclear.

Impact of Body Weight Loss During Preoperative Chemoradiotherapy on Prognosis of Patients With Lower Rectal Cancer

Annals of Gastroenterological Surgery, EarlyView.
The present study aimed to investigate the relationship between changes in body weight and composition during chemoradiotherapy, such as the psoas muscle mass index, visceral fat index, and subcutaneous fat index obtained from computed tomography images, and long‐term outcomes in rectal cancer patients.

Psoas Muscle Volume as a Predictor of Postoperative Complications in Patients Undergoing Emergency Surgery for Strangulated Small Bowel Obstruction: A Retrospective Single‐Center Study

Annals of Gastroenterological Surgery, EarlyView.
This retrospective study identified low preoperative psoas muscle volume, measured by computed tomography, as an independent predictor of postoperative complications in patients undergoing emergency surgery for strangulated small bowel obstruction. Low psoas muscle volume, particularly in older adults, was associated with cardiopulmonary and systemic ...

Lumbar Bone Stress Injuries in Cricket Fast Bowlers: A Review

Journal of Clinical Orthopaedics
Lumbar Bone Stress Injuries (LBSI) encompass a spectrum ranging from bone stress reactions to lumbar stress fractures (LSF). These injuries are among the most prevalent in cricket players, particularly fast bowlers.

Prognostic Value of Psoas Major Muscle Volume in Assessing Sarcopenia in Elderly Patients With Rectal Cancer

Annals of Gastroenterological Surgery, EarlyView.
This study investigates the prognostic utility of a novel volumetric indicator—psoas volume index (PVI)—for assessing sarcopenia in elderly rectal cancer patients. Sarcopenia classified by our proposed PVI cut‐off values was associated with poor nutritional and inflammatory status, and patients with low PVI showed significantly worse long‐term outcomes.

Adaptation of thoracic and lumbar curvature and spinal muscle activity under changing gravity

Frontiers in Physiology
IntroductionThe effect of micro-gravity on the lumbar and in particular thoracic regions is poorly understood. The aim of this study was to evaluate spinal curvature across the lumbar and thoracic region, and extensor muscle activity during acute micro ...

Impact of Abdominoperineal Resection on Postoperative Male Sexual Function After Minimally Invasive Rectal Cancer Surgery: A Subgroup Analysis From the LANDMARC Study

Annals of Gastroenterological Surgery, EarlyView.
Abdominoperineal resection (APR) after minimally invasive rectal cancer surgery was associated with significantly higher rates of erectile and early ejaculatory dysfunction compared with anal‐sparing surgery. Although ejaculatory function showed partial recovery over time, erectile dysfunction persisted up to 12 months postoperatively.
