Psoas muscle index predicts osteoporosis and fracture risk in individuals with degenerative spinal disease

Yuya Kajiki et al.

Summary: The study found a significant correlation between psoas muscle index (PMI), bone mineral density, and fracture risk. PMI may help increase the accuracy of diagnosing osteoporosis and fracture risk.

Critical Role of Estrogens on Bone Homeostasis in Both Male and Female: From Physiology to Medical Implications

Emmanuelle Noirrit-Esclassan et al.

Summary: Bone is a versatile tissue that is regulated by estrogens, with estrogen deficiency being a major cause of postmenopausal osteoporosis. The effects of estrogens on bone are dependent on bone type, tissue, cell types involved, and gender. New ongoing strategies are being discussed to optimize the benefits and risks of hormonal treatment for menopause.

Paravertebral Muscles as Indexes of Sarcopenia and Sarcopenic Obesity: Comparison With Imaging and Muscle Function Indexes and Impact on Cardiovascular and Metabolic Disorders

Hyung Suk Seo et al.

Summary: This study proposed the use of PMA and PVR as new indexes of sarcopenia and sarcopenic obesity, showing clinical associations with hypertension and diabetes. High PVR was associated with low risks for hypertension and diabetes.

The global prevalence of osteoporosis in the world: a comprehensive systematic review and meta-analysis

Nader Salari et al.

Summary: This study conducted a systematic review and meta-analysis to investigate the global prevalence of osteoporosis. The results showed an overall prevalence of 18.3%, with higher rates in women (23.1%) compared to men (11.7%). Africa had the highest prevalence of osteoporosis at 39.5%.

Association of sarcopenia with incident osteoporosis: a prospective study of 168,682 UK biobank participants

Fanny Petermann-Rocha et al.

Summary: The study found that pre-sarcopenia in men and sarcopenia in women were associated with a higher risk of developing osteoporosis. Low muscle mass and slow gait speed were associated with an increased risk of incident osteoporosis, while low grip strength was specifically linked to higher risk in men.

Application of bone turnover markers and DXA and QCT in an elderly Chinese male population

Yuan Yuan et al.

Summary: In elderly Chinese males, spine QCT has a higher OP detection rate than DXA, while hip DXA is more advantageous in predicting the risk of fragility fracture. tPINP, beta-CTX, and OC can serve as reliable indicators for dynamically monitoring bone content changes and may identify early bone metabolism abnormalities even when BMD examinations are negative.
