Meta-Analysis
BACKGROUND
The ageing population brings about the appearance of age-related health disorders, such as osteoporosis or osteopenia. These disorders are associated with fragility fractures. The impact is greater among postmenopausal women due to an acceleration of bone mineral density (BMD) loss.
OBJECTIVE
To estimate the effectiveness of Pilates or Yoga on BMD in adult women.
METHODS
Five electronics databases were searched up to April 2021. Randomized controlled trials (RCTs), non-RCTs and pre-post studies were included. The main outcome was BMD. Risk of bias was evaluated using the Cochrane risk of bias tool. A random effects model was used to pool data from primary studies. Subgroup analyses based on the type of exercise were conducted.
RESULTS
Eleven studies including 591 participants aged between 45 and 78 years were included. The mean length of the interventions ranged from 12 to 32 weeks, and two studies were performed for a period of at least one year. The pooled effect size for the effect of the intervention (Pilates/Yoga) vs the control group was 0.07 (95% Confidence interval [CI]: -0.05 to 0.19; I2 = 0.0%), and 0.10 (95% CI: 0.01 to 0.18; I2 = 18.4%) for the secondary analysis of the pre-post intervention.
CONCLUSIONS
Despite of the non-significant results, the BMD maintenance in the postmenopausal population, when BMD detrimental is expected, could be understood as a positive result added to the beneficial impact of Pilates-Yoga in multiple fracture risk factors, including but not limited to, strength and balance.

Randomized Controlled Trial
Anabolic therapies, recommended for patients at very high fracture risk, are administered subcutaneously (SC). The objective of this study was to evaluate the efficacy and safety of the abaloparatide microstructured transdermal system (abaloparatide-sMTS) as an alternative to the SC formulation. This phase 3, noninferiority study (NCT04064411) randomly assigned postmenopausal women with osteoporosis (N = 511) 1:1 to open-label abaloparatide administered daily via abaloparatide-sMTS or SC injection for 12 months. The primary comparison between treatment groups was the percentage change in lumbar spine bone mineral density (BMD) at 12 months, with a noninferiority margin of 2.0%. Secondary endpoints included percentage change in total hip and femoral neck BMD, bone turnover markers, dermatologic safety, and new clinical fracture incidence. At 12 months, percentage increase from baseline in lumbar spine BMD was 7.14% (SE: 0.46%) for abaloparatide-sMTS and 10.86% (SE: 0.48%) for abaloparatide-SC (treatment difference: -3.72% [95% confidence interval: -5.01%, -2.43%]). Percentage change in total hip BMD was 1.97% for abaloparatide-sMTS and 3.70% for abaloparatide-SC. Median changes from baseline at 12 months in serum procollagen type I N-terminal propeptide (s-PINP) were 52.6% for abaloparatide-sMTS and 74.5% for abaloparatide-SC. Administration site reactions were the most frequently reported adverse events (abaloparatide-sMTS, 94.4%; abaloparatide-SC, 70.5%). Incidence of serious adverse events was similar between groups. Mild or moderate skin reactions occurred with abaloparatide-sMTS with no identifiable risk factors for sensitization reactions. Few new clinical fractures occurred in either group. Noninferiority of abaloparatide-sMTS to abaloparatide-SC for percentage change in spine BMD at 12 months was not demonstrated; however, clinically meaningful increases from baseline in lumbar spine and total hip BMD were observed in both treatment groups. © 2023 Radius Health, Inc and The Authors.

Frontiers in Endocrinology 2022To explore the genetic causal association between osteoporosis (OP) and iron status through Mendelian randomization (MR).
OBJECTIVE
To explore the genetic causal association between osteoporosis (OP) and iron status through Mendelian randomization (MR).
METHODS
Publicly available genome-wide association study (GWAS) summary data were used for MR analysis with four iron status-related indicators (ferritin, iron, total iron binding capacity, and transferrin saturation) as exposures and three different types of OP (OP, OP with pathological fracture, and postmenopausal OP with pathological fracture) as outcomes. The inverse-variance weighted (IVW) method was used to analyze the genetic causal association between the four indicators of iron status and OP. The heterogeneity of MR results was determined using IVW and MR-Egger methods. The pleiotropy of MR results was determined using MR-Egger regression. A leave-one-SNP-out test was performed to determine whether the MR results were affected by a single nucleotide polymorphism (SNP). The weighted median method was conducted to further validate our results.
RESULTS
Based on IVW, MR-Egger and weighted median models, we found no causal association between iron status (ferritin, iron, total iron binding capacity, or transferrin saturation) and OP (P > 0.05 in all models). IVW and MR-Egger analysis of OP with pathological fracture and iron status indicators showed no potential genetic causal association (P> 0.05 in the two analyses). The results of the weighted median were consistent with those of IVW (P> 0.05 in all analyses). There was no potential genetic causal association between iron status and postmenopausal OP with pathological fracture based on serum iron (P>0.05 in all models). No heterogeneity or horizontal pleiotropy was found in any of the analyses. None of the leave-one-out tests in the analyses found any SNP that could affect the results of MR.
CONCLUSION
Our results demonstrate that there is no genetic causal association between OP and iron status, but the effects of other factors were not excluded.

Review
Osteoporosis and low bone density are associated with a risk of fracture as a result of even minimally traumatic events. The estimated lifetime risk of osteoporotic fracture is as high as 50 percent, especially in white and Asian women. The use of caffeine, tobacco and steroids is associated with a decrease in bone density. Cognitive impairment, vision problems and postural instability increase the risk of falling and sustaining a fracture. Medications such as long-acting sedative hypnotics, anticonvulsants and tricyclic antidepressants also increase this risk. Combinations of clinical and radiographic findings can predict fracture risk more effectively than bone densitometry, but often only after the first fracture has occurred. The addition of dietary calcium and/or vitamin D is clearly both cost-effective and significant in reducing the likelihood of fractures. Bisphosphonates reduce fracture risk but at a cost that may be prohibitive for some patients. Estrogen and estrogen-receptor modulators have not been well studied in randomized trials evaluating the reduction of fractures, but they are known to increase bone density. Pharmacologic therapy and the reduction of sensory and environmental hazards can prevent osteoporotic fractures in some patients.

BACKGROUND
Postmenopausal osteoporosis (PMOP) is a prevalent bone disorder with significant global impact. The elevated risk of osteoporotic fracture in elderly women poses a substantial burden on individuals and society. Unfortunately, the current lack of dependable diagnostic markers and precise therapeutic targets for PMOP remains a major challenge.
METHODS
PMOP-related datasets GSE7429, GSE56814, GSE56815, and GSE147287, were downloaded from the GEO database. The DEGs were identified by "limma" packages. WGCNA and Machine Learning were used to choose key module genes highly related to PMOP. GSEA, DO, GO, and KEGG enrichment analysis was performed on all DEGs and the selected key hub genes. The PPI network was constructed through the GeneMANIA database. ROC curves and AUC values validated the diagnostic values of the hub genes in both training and validation datasets. xCell immune infiltration and single-cell analysis identified the hub genes' function on immune reaction in PMOP. Pan-cancer analysis revealed the role of the hub genes in cancers.
RESULTS
A total of 1278 DEGs were identified between PMOP patients and the healthy controls. The purple module and cyan module were selected as the key modules and 112 common genes were selected after combining the DEGs and module genes. Five Machine Learning algorithms screened three hub genes (KCNJ2, HIPK1, and ROCK1), and a PPI network was constructed for the hub genes. ROC curves validate the diagnostic values of ROCK1 in both the training (AUC = 0.73) and validation datasets of PMOP (AUC = 0.81). GSEA was performed for the low-ROCK1 patients, and the top enriched field included protein binding and immune reaction. DCs and NKT cells were highly expressed in PMOP. Pan-cancer analysis showed a correlation between low ROCK1 expression and SKCM as well as renal tumors (KIRP, KICH, and KIRC).
CONCLUSIONS
ROCK1 was significantly associated with the pathogenesis and immune infiltration of PMOP, and influenced cancer development, progression, and prognosis, which provided a potential therapy target for PMOP and tumors. However, further laboratory and clinical evidence is required before the clinical application of ROCK1 as a therapeutic target.

Meta-Analysis Review
The purpose of this study was to perform a meta-analysis to examine the efficacy and safety of denosumab in postmenopausal women with osteoporosis.Medline, Cochrane Library, EMBASE, and Google Scholar databases were searched until October 30, 2014 using combinations of the following search terms: osteoporosis, postmenopause, postmenopausal, women, denosumab. The primary outcome was bone mineral density (BMD) change, and secondary outcomes were change in the bone turnover markers β-isomerized carboxy-terminal cross-linking telopeptide of type I collagen (CTX) and serum procollagen type I amino-terminal propeptide (P1NP), and adverse events.Patients treated with denosumab had significantly increased BMD of the lumbar spine (7.58%), total hip (4.86%), and distal third of the radius (2.92%) than those treated with placebo (all, P < 0.001). Patients treated with denosumab had a significant decrease of CTX (-66.16%) and P1NP (-64.65%) as compared with those treated with placebo (both, P < 0.001). Adverse events were similar between the 2 groups (pooled odds ratio = 1.04, P = 0.625).Denosumab increases BMD and decreases markers of bone turnover in postmenopausal women with osteoporosis, and is not associated with significant side-effects.

Review
T cells and B cells produce large amounts of cytokines which regulate bone resorption and bone formation. These factors play a critical role in the regulation of bone turnover in health and disease. In addition, immune cells of the bone marrow regulate bone homeostasis by cross-talking with bone marrow stromal cells and osteoblastic cells via cell surface molecules. These regulatory mechanisms are particularly relevant for postmenopausal osteoporosis and hyperparathyroidism, two common forms of bone loss caused primarily by an expansion of the osteoclastic pool only partially compensated by a stimulation of bone formation. This article describes the cytokines and immune factors that regulate bone cells, the immune cells relevant to bone, examines the connection between T cells and bone in health and disease, and reviews the evidence in favor of a link between T cells and the mechanism of action of estrogen and PTH in bone.

Review
With declining mortality rates, the number of breast cancer survivors is increasing. Ongoing care after breast cancer treatment is often provided by primary care physicians. This care includes surveillance for cancer recurrence with a history and physical examination every three to six months for the first three years after treatment, every six to 12 months for two more years, and annually thereafter. Mammography is performed annually. Magnetic resonance imaging of the breast is not indicated unless patients are at high risk of recurrence, such as having a hereditary cancer syndrome. Many breast cancer survivors experience long-term sequelae from the disease or treatment. Premature menopause with hot flashes can occur and is managed with pharmacologic and nonpharmacologic treatments. Vaginal dryness is treated with vaginal lubricants and gels. Because cardiotoxicity from chemotherapy is possible, clinicians should be alert for this complication and perform echocardiography if appropriate. Impaired cognition after chemotherapy is also common; treatment includes cognitive rehabilitation therapy. Patients with treatment-induced menopause develop decreased bone density and should receive dual energy x-ray absorptiometry and pharmacologic and nonpharmacologic therapies. Others experience lymphedema, often best managed with weight loss and complex decongestive therapy. Some women develop chronic pain, which is treated by addressing psychological factors and with appropriate pharmacologic therapy.
