Background: A rapid increase in bone turnover and bone loss has been observed in response to the discontinuation of denosumab. It led to an acute increase in the fracture risk, similar to that observed in the untreated patients. We aimed to investigate the effect of denosumab on osteoclast (OC) precursor cells compared to that of zoledronate.
Methods: The study compared the effects of denosumab (60 mg/24-week) and zoledronate (5 mg/48-week) over 48 weeks in postmenopausal women with osteoporosis. From patients' peripheral mononuclear cells, CD14+/CD11b+/vitronectin receptor (VNR)- and CD14+/CD11b+/VNR+ cells were isolated using fluorescent-activated cell sorting, representing early and late OC precursors, respectively. The primary endpoint was the changes in OC precursors after 48 weeks of treatment.
Results: Among the 23 patients, 11 were assigned to the denosumab group and 12 to the zoledronate group (mean age, 69 years). After 48 weeks, the changes in OC precursors were similar between and within the groups. Serum C-terminal telopeptide of type I collagen levels were inversely correlated with OC precursor levels after denosumab treatment (r=-0.72, P<0.001). Lumbar spine, femur neck, and total hip bone mineral density (BMD) increased in both groups. Lumbar spine BMD increased more significantly in the denosumab group than in the zoledronate group.
Conclusions: Denosumab and zoledronate treatments induced similar changes in OC precursors. During denosumab treatment, old age and suppressed bone turnover were associated with increased OC precursor cell populations. Further validation studies with prospective designs are required.

Aim: The association between obstructive sleep apnea (OSA) and prediabetes using the STOP-Bang questionnaire remains unknown. We aimed to investigate the prevalence of prediabetes among people based on their sleep apnea status.
Methods: This cross-sectional study included 10131 Korean adults without diabetes with information of STOP-Bang scores, drawn from the dataset of the Korea National Health and Nutrition Examination Survey 2019-2021.
Objective: To assess treatment efficacy over one year in women with recurrent urinary tract infection (UTI) receiving extended treatment-strength antibiotics compared to standard low-dose prophylactic antibiotic regimens.
Methods: A retrospective cohort study of adult women presenting with acute uncomplicated UTI between January 1, 2018 and October 1, 2020 meeting recurrent UTI criteria (≥2 in 6 months or ≥3 in one year). Women were offered either: 1) treatment-strength antibiotic therapy for 1 month; or 2) up to 7 days of treatment-strength antibiotics followed by ≥3-months of low-dose prophylactic antibiotics.

Introduction: The human skin acts as a protective barrier against external pathogens and hosts a diverse microbiome consisting of bacteria, fungi, viruses, and archaea. Disruptions to the skin microbiome can impact immune function, leading to inflammatory and autoimmune conditions. The importance of pH for the microbiome is paramount.

Unlabelled: This study examined how isoflavone interventions impact bone health in postmenopausal women. Analyzing 73 trials found that isoflavones reduce bone resorption markers, enhance bone minerals, and increase hormones regulating bone metabolism. This suggests that isoflavones could help address bone health issues in postmenopausal women.

Background: The role of endogenous estrogen exposure (EEE) in shaping body composition and its implications for cardiometabolic health remain understudied despite its potential significance. This cross-sectional study aimed to investigate the association between EEE and body composition indices among postmenopausal women.
Methods: Data were obtained from the Tehran Lipid and Glucose Study (TLGS), including 960 women aged over 40 years.
