Abstract
OBJECTIVES To evaluate the risk of subsequent fractures in patients who attended the Fracture Liaison Service (FLS), with and without incident falls after the index fracture. DESIGN A 3-year prospective observational cohort study. SETTING An outpatient FLS in the Netherlands. PARTICIPANTS Patients aged 50+ years with a recent clinical fracture. OUTCOME MEASURES Incident falls and subsequent fractures. RESULTS The study included 488 patients (71.9% women, mean age: 64.6±8.6 years). During the 3-year follow-up, 959 falls had been ascertained in 296 patients (60.7%) (ie, fallers), and 60 subsequent fractures were ascertained in 53 patients (10.9%). Of the fractures, 47 (78.3%) were fall related, of which 25 (53.2%) were sustained at the first fall incident at a median of 34 weeks. An incident fall was associated with an approximately 9-fold (HR: 8.6, 95% CI 3.1 to 23.8) increase in the risk of subsequent fractures. CONCLUSION These data suggest that subsequent fractures among patients on treatment prescribed in an FLS setting are common, and that an incident fall is a strong predictor of subsequent fracture risk. Immediate attention for fall risk could be beneficial in an FLS model of care. TRIAL REGISTRATION NUMBER NL45707.072.13.

PloS one. 2022;(2):e0264064
Abstract
OBJECTIVE There have been concerns regarding the high prevalence of vitamin D deficiency in the United Arab Emirates and the association between this prevalence and cardiovascular risk. Vitamin D deficiency is a global public health problem, with a high prevalence in the Abu Dhabi national population. This cross-sectional retrospective observational study aimed to elucidate vitamin D deficiency symptoms and contributing factors in this context. METHOD AND SAMPLING Among 12346 participants presenting for their Weqaya population comprehensive cardiovascular risk factor screening, 700 were randomly selected and telephoned, among whom 400 completed a questionnaire that elicited information on dietary intake, sun exposure, clothing, physical activity, and symptoms related to vitamin D deficiency. RESULTS Higher vitamin D levels were noted in participants who consumed extra servings of cod liver oil, tuna, salmon, and eggs; who wore clothes with their arms and legs exposed; and who performed daily physical activity. Symptoms of hypovitaminosis D (bone pain) were more frequently found in females. Fatigue is significantly associated with low vitamin D and younger participants. Strategies focusing on health promotion and lifestyle interventions should be implemented to address vitamin D deficiency.

Endocrinology of bone mineralization: An update.
Jannin, A, Kerlan, V, Desailloud, R
Annales d'endocrinologie. 2022;(1):46-53
Abstract
Throughout the world, millions of people suffer from fragilizing osteopathies such as osteomalacia and osteoporosis. Osteomalacia is a rare disorder, corresponding to mineralization abnormalities in adult bone, as opposed to rickets in children. Renal phosphate loss and hypophosphatasia are the main causes of vitamin-resistant osteomalacia. Diagnosis is based on clinical history, phosphocalcic metabolism assessment and, if necessary, molecular characterization, and must be rapid in order to initiate the most appropriate treatment and consider new treatments such as burosumab if necessary. Osteoporosis is characterized by reduced bone mass and strength, which increases the risk of fragility fracture. Fracture-related burden is expected to increase over the coming decades linked to the aging of population and a treatment gap. In order to reduce this treatment gap, it is important to develop two strategies: improvement of screening and of treatment. Systematic screening using the FRAX® fracture risk assessment tool could be useful to increase anti-osteoporosis medical treatment and reduce fracture rates. The question of treatment sequencing in osteoporosis is another challenge, notably after denosumab cessation, complicated by a decrease in bone mineral density and increased risk of fracture. New treatments are also available, including romosozumab, a humanized monoclonal antibody, which promotes bone formation and inhibits bone resorption by inhibiting sclerostin. Romosozumab is approved in several countries, including France, for treating severe osteoporosis in postmenopausal women at high risk of fracture and free of cardiovascular comorbidity. Endocrinologists need to be aware of these fragilizing osteopathies in order to improve both diagnosis and treatment.

Abstract
BACKGROUND Osteosarcopenia is a geriatric syndrome defined by the concomitant presence of osteopenia/osteoporosis (loss of bone mineral density (BMD)) and sarcopenia (loss of muscle mass and/or function), which increases the risk of falls, fractures, and premature mortality. OBJECTIVE To examine the efficacy of non-pharmacological (exercise and/or nutritional) interventions on musculoskeletal measures and outcomes in osteosarcopenic adults by reviewing findings from randomized controlled trials (RCTs). METHODS This review was registered at PROSPERO (registration number: CRD42020179292) and conducted in accordance with the PRISMA guidelines. Electronic databases were searched for RCTs assessing the effect of at least one non-pharmacological intervention (any form of exercise and/or supplementation with protein, vitamin D, calcium or creatine) on any musculoskeletal measure/outcome of interest (BMD, bone strength/turnover, muscle mass and strength, physical performance, falls/fractures) in adults with osteosarcopenia as defined by any proposed criteria. RESULTS Two RCTs (of n=106 older osteosarcopenic adults (≥65 years)) assessing the effects of progressive resistance training (RT) (via resistance bands or machines; 2-3 times/week; ~60 minutes in duration) were eligible for inclusion. The two RCTs demonstrated moderate quality evidence that RT increases muscle mass, strength, and quality, with changes in strength and quality occurring before muscle mass (12 vs 28 weeks). There was low quality evidence that RT increases lumbar spine BMD and maintains total hip BMD when performed for 12 and 18 months, respectively, and moderate quality evidence that RT has no effect on markers of bone turnover or physical performance. No major adverse effects were recorded in either of the RCTs. There were no eligible RCTs examining the impact of nutritional interventions. CONCLUSION Chronic RT is safe and effective at potentiating gains in muscle mass, strength, and quality, and increasing or maintaining BMD in older osteosarcopenic adults. No RCT has examined the effects of protein, vitamin D, calcium, or creatine against a control/placebo in this high-risk population.

Nutritional Supplements and Skeletal Health.
Tabatabai, LS, Sellmeyer, DE
Current osteoporosis reports. 2021;(1):23-33
Abstract
PURPOSE OF REVIEW Nutrition influences skeletal health throughout the lifespan, from the impact of maternal intakes during development, through the development of peak bone mass, to the rate of bone loss during aging. However, there are limited data available on the effects of nutritional supplements on bone density, let alone fracture risk. This review will assess the current literature, focusing on human studies, and emphasizing nutrients where bone density or fracture data are available. RECENT FINDINGS Calcium and vitamin D supplements, in combination, reduce fracture risk, particularly in populations with low intakes. Extensive recent analyses have supported the safety of these interventions at recommended intakes. There is growing evidence that specific isoflavones may improve bone density although fracture data are lacking. Multiple other nutrient supplements may benefit skeletal health, but data are limited. The effect size of nutrient interventions are relatively small, requiring large sample sizes for trials with bone outcomes, may be difficult to blind, and the impact of supplementation may depend on baseline intake. However, nutrition is the only intervention that can be implemented life long and on a population wide basis. Further investigation is needed into the potential benefits of nutritional supplements to determine in which settings supplements may add benefit in addition to dietary intakes.

Poivret, D, Goetz, C, Zevering, Y, Wilcke, C, Noirez, V
International journal of rheumatic diseases. 2021;(7):912-921
Abstract
AIM: Osteoporosis is a major risk factor for fractures. Poor persistence with osteoporosis medication hampers outcomes. This study assessed whether encouraging the formation of patient-led follow-up cooperatives between general practitioners (GPs) and community pharmacists improved medication persistence. METHODS All consecutive patients who attended an osteoporosis patient education program were invited to participate. They were given a logbook containing questionnaires they would bring to 6-monthly visits to their GP and pharmacist. The effect of this 3-year cooperative follow-up on persistence with medication and lifestyle changes was assessed. RESULTS In total, 121 patients (average age, 67 years; 93% female) participated. Poor cooperation between GPs and pharmacists was noted. Nevertheless, medication persistence ranged from 83% to 91% over the 6 visits. However, since patient drop-out rates were high and questionnaire return rates were low, a post-study medical chart review was performed. This confirmed that persistence was high (74%-83%) at 3 years post-enrollment, even for oral bisphosphonate-treated patients (73%-76%). However, adoption of anti-osteoporosis lifestyle changes was poor throughout the study: one- to two-thirds of the patients did not alter their diet, physical activity, or surroundings to prevent falls. CONCLUSION One study goal, namely, to encourage GPs and pharmacists to cooperate in patient follow-up, was not achieved. However, high medication persistence was observed. This may reflect the education program, patient empowerment, personalized attention from study personnel, and being in a study. Patient-centered approaches can thus significantly increase medication persistence in osteoporosis. Ongoing education may be needed to improve patient adoption of and persistence with lifestyle changes.

Prospective Association of the Portfolio Diet with All-Cause and Cause-Specific Mortality Risk in the Mr. OS and Ms. OS Study.
Lo, K, Glenn, AJ, Yeung, S, Kendall, CWC, Sievenpiper, JL, Jenkins, DJA, Woo, J
Nutrients. 2021;(12)
Abstract
The Portfolio Diet has demonstrated its cardiovascular benefit from interventions, but the association between Portfolio Diet adherence and the risk of all-cause and cause-specific mortality has not been examined in Chinese population. The present study has collected Portfolio Diet adherence (assessed by food frequency questionnaire), lifestyle factors and mortality status of 3991 participants in the Mr. Osteoporosis (OS) and Ms. OS Study. Cox regression models were used to examine the association between the Portfolio Diet adherence and mortality risk (all-cause, cardiovascular disease or cancer). The highest quartile of the Portfolio Diet score was associated with a 28% lower risk of all-cause (hazard ratio, HR: 0.72) and cancer (HR: 0.72) mortality, respectively. The association between Portfolio Diet adherence and cardiovascular disease mortality did not reach statistical significance (HR: 0.90, 95% CI = 0.64, 1.26). Among male participants, the highest adherence to the Portfolio Diet was also associated with a lower risk of all-cause (HR: 0.63) and cancer mortality (HR: 0.59), and there was an inverse association between food sources of plant protein and the risk of cardiovascular mortality (HR: 0.50). However, most associations between the Portfolio Diet and mortality were not significant among females. The protection for cancer mortality risk might reach the plateau at the highest adherence to the Portfolio Diet for females. To conclude, greater adherence to the Portfolio Diet was significantly associated with a lower risk of mortality in Hong Kong older adults, and the associations appeared stronger among males.

Abstract
BACKGROUND Osteoporosis is a frequent musculoskeletal condition with significant complications that would be a global health problem and one of the major causes of mortality and morbidity. OBJECTIVES The current study aimed to ascertain the impact of pulsed magnetic therapy, aerobic exercise, and a combination of both modalities on osteoporotic female patients postthyroidectomy. METHODS Between May 2018 and September 2019, 45 female patients with osteoporosis were included in the randomized clinical study, their age ranged from 40 to 50 years, had thyroidectomy for at least 6 months ago, and had an inactive lifestyle for at least the previous 6 months. Patients were assigned randomly into 3 equal groups. Group A (magnetic therapy group): received routine medical treatment (bisphosphonates, calcium, and vitamin D) in addition to pulsed magnetic therapy on the hip region for 12 weeks (3 sessions/week). Group B (exercise group): received routine medical treatment plus moderate-intensity aerobic exercise for 12 weeks (3 sessions/week). Group C (combined magnetic therapy and exercise therapy group): received routine medical treatment plus pulsed magnetic therapy and moderate-intensity aerobic exercise for 12 weeks (3 sessions/week). The 3 groups were assessed for bone mineral density (BMD) at baseline by dual-energy x-ray absorptiometry and after 12 weeks of treatment. RESULTS The results showed that within-group analysis a statistically significant increase was reveled (P < .05) for BMD in the 3 studied groups. Comparing the results among the 3 tested groups revealed a significant increase (P < .05) in posttesting mean values of BMD in group (C) compared to group (A) and group (B). No significant statistical difference in BMD means values between the 2 groups (A) and (B) after testing was detected. CONCLUSION Combination of both pulsed magnetic therapy and moderate-intensity aerobic exercise showed significant improvement in BMD at the hip region than using any of the 2 modalities alone.

Microscopic Colitis Is Not an Independent Risk Factor for Low Bone Density.
Graziano, EJ, Vaughn, BP, Wang, Q, Chow, LS, Campbell, JP
Digestive diseases and sciences. 2021;(10):3542-3547
Abstract
BACKGROUND Microscopic colitis (MC) is a subtype of inflammatory bowel disease (IBD) with overlapping risk factors for low bone density (LBD). While LBD is a known complication of IBD, its association with MC is not well-established. AIMS Assess the prevalence of LBD in MC compared to control populations, and evaluate if MC predicts LBD when controlling for confounders. METHODS Retrospective, observational case control study of adult patients with pathologically confirmed MC from 2005 to 2015. Bone density measurements were abstracted from dual-energy X-ray absorptiometry (DEXA) reports, and bone density was classified using T-score: normal (T ≥ - 1.0), osteopenia (- 1.0 > T > -2.5) or osteoporosis (T ≤ - 2.5). Demographics, disease, medication history and LBD risk factors were obtained from chart review. Prevalence of LBD was compared to national and local controls. A matched control cohort to MC patients without prior diagnosis of LBD was analyzed with logistic regression to assess the relationship of MC to LBD. RESULTS One hundred and eighteen patients with MC were identified. Osteopenia in women with MC was more prevalent compared to national controls (67% vs. 49%, p = 0.0004), and LBD was more prevalent in MC patients compared to local controls (82% vs. 55%, p < 0.0001). In MC patients without prior diagnosis of LBD matched to controls, there was a higher prevalence of osteopenia (53.2% vs. 36.7%, p = 0.04). However, after controlling for confounders, MC was not associated with LBD (OR 0.83, 95% CI 0.22, 3.16, p = 0.8). CONCLUSIONS While LBD was more prevalent in MC patients compared to control populations, with adjustment for key confounders (including BMI, steroids, smoking, vitamin D and calcium use), MC was not an independent predictor of LBD.

Critical Role of Estrogens on Bone Homeostasis in Both Male and Female: From Physiology to Medical Implications.
Emmanuelle, NE, Marie-Cécile, V, Florence, T, Jean-François, A, Françoise, L, Coralie, F, Alexia, V
International journal of molecular sciences. 2021;(4)
Abstract
Bone is a multi-skilled tissue, protecting major organs, regulating calcium phosphate balance and producing hormones. Its development during childhood determines height and stature as well as resistance against fracture in advanced age. Estrogens are key regulators of bone turnover in both females and males. These hormones play a major role in longitudinal and width growth throughout puberty as well as in the regulation of bone turnover. In women, estrogen deficiency is one of the major causes of postmenopausal osteoporosis. In this review, we will summarize the main clinical and experimental studies reporting the effects of estrogens not only in females but also in males, during different life stages. Effects of estrogens on bone involve either Estrogen Receptor (ER)α or ERβ depending on the type of bone (femur, vertebrae, tibia, mandible), the compartment (trabecular or cortical), cell types involved (osteoclasts, osteoblasts and osteocytes) and sex. Finally, we will discuss new ongoing strategies to increase the benefit/risk ratio of the hormonal treatment of menopause.
