The association between adolescents' independent food purchasing and dietary quality differs by socioeconomic status: Findings from a pilot study.

During adolescence, many young people start to make more independent food purchases. Subsequently, these independent food choices will increasingly contribute to their overall diet quality; little is known, however, about this relationship. This pilot study aimed to examine the role adolescents' independent food purchases play in their diet quality and assess if these relationships vary according to socio-economic status.

Vitamin D insufficiency in pregnant women from Lebanon: prevalence and key predictors.

Background: Suboptimal 25-hydroxyvitamin D (25OHD) during pregnancy can have adverse maternal and neonatal outcomes.

Aim: This study aimed to estimate the prevalence of vitamin D deficiency in pregnant females in Lebanon and to identify its risk factors.

Methods: This is a cross-sectional study involving pregnant females identified during their first-early second trimester visit to obstetricians in two centers in Beirut.

Family history of fracture and fracture risk: a meta-analysis to update the FRAX® risk assessment tool.

Unlabelled: In the largest meta-analysis of international cohorts to date, a family history of fracture is confirmed as a significant BMD-independent predictor of future fracture risk. Parental and sibling histories of fracture carry the same significance for future fracture, including the impact of family hip fracture on future hip fracture risk.

Purpose: We have undertaken a meta-analysis of international prospective cohorts to quantify the relationship between a family history of fracture and future fracture incidence.

Barriers and solutions for global access to osteoporosis management: a Position Paper from the International Osteoporosis Foundation.

Our ability to optimally manage bone health across the lifecourse, and so minimise the risk of fractures, has advanced substantially in recent decades. Whilst fractures and osteoporosis in older age were historically viewed simply as inherent in normal ageing, they are now recognised as manifestations of age-related disease. Key to advancing the field was the development of conceptual (relating to impaired bone mass and microarchitecture with increased propensity to fracture), and subsequent World Health Organization densitometric definitions of osteoporosis, cementing the role of dual-energy X-ray absorptiometry in bone health management.

PainDETECT as a Potential Tool for Personalized Medicine: Predicting Outcome One Year After Knee Arthroplasty.

Objective: To investigate whether neuropathic-like pain, identified using the PainDETECT questionnaire, predicts postoperative symptoms, using data from 2 independent, prospective cohort studies.

Patients And Methods: Data were collected from patients undergoing primary knee arthroplasty for primary osteoarthritis recruited to the Evaluation of perioperative Pain in Osteoarthritis of the kNEe (EPIONE) Study n=120, from October 1, 2011, to May 30, 2014, and the Clinical Outcomes in Arthroplasty Study (COASt) n=404, from January 1, 2010, to December 31, 2018). The PainDETECT questionnaire score was used to divide patients into nociceptive (<13), unclear (13-18), and neuropathic pain (>18) groups preoperatively using validated cutoffs.

Body mass index and subsequent fracture risk: A meta-analysis to update FRAX®.

The aim of this international meta-analysis was to quantify the predictive value of body mass index (BMI) for incident fracture and relationship of this risk with age, sex, follow-up time and bone mineral density (BMD). 1 667 922 men and women from 32 countries (63 cohorts), followed for a total of 16.0 million person-years were studied.

Parathyroid hormone receptor agonists in the management of osteoporosis.

Parathyroid hormone (PTH) regulates bone homeostasis. Intermittent exposure to PTH results in bone formation being greater than bone resorption, and this effect has been harnessed through the development of agonists of the PTH and PTH-related protein type 1 receptor (PTH1R) to treat osteoporosis. Teriparatide, an analogue of the first 34 amino acids of PTH, and abaloparatide, which resembles PTH-related protein (PTHrP) in structure, are PTH1R agonists currently in clinical use.

Type 1 and 2 diabetes mellitus: comprehensive fracture risk relationships in UK Biobank.

We aimed to investigate associations between diabetes mellitus and incident fracture, stratified by diabetes type (1 or 2), disease duration and microvascular complications of diabetes. This prospective cohort analysis used data from the UK Biobank, a large population-based cohort of participants recruited 2006-2010 at age 40-69 yr. The exposure was type 1 or type 2 diabetes at baseline, with the outcome of first incident osteoporotic fracture.

Pregnancy vitamin D supplementation and bone mineral density of the mother: a post hoc analysis of the MAVIDOS randomised placebo-controlled trial.

Unlabelled: The effect of pregnancy vitamin D supplementation on bone mineral density (BMD) in the mother immediately after delivery and at 4 years after delivery was assessed in a randomised placebo-controlled trial. The mothers' BMD did not differ between the two intervention groups.

Purpose: Vitamin D supplementation during pregnancy has positive effects on the offspring's bone development and bone mineral density (BMD) in childhood, but there are limited data on the effects on the mother's skeleton.

Antiresorptive Therapy to Reduce Fracture Risk and Effects on Dental Implant Outcomes in Patients With Osteoporosis: A Systematic Review and Osteonecrosis of the Jaw Taskforce Consensus Statement.

Objective: Placement of a dental implant in a patient on antiresorptive therapy has been hypothesized to increase the risk of medication-related osteonecrosis of the jaw (MRONJ) and/or impact implant survival. In patients with osteoporosis, the risk of MRONJ with antiresorptive therapy is only marginally higher than observed in the general population.

Methods: The International ONJ Taskforce conducted a systematic review of the literature and evaluated the outcomes of implant placement in individuals with osteoporosis receiving antiresorptive therapy.

Associations of Markers of Inflammatory Status and Adiposity with Bone Phenotype at Age 60-64 Years: Findings from the MRC National Survey of Health and Development.

This study investigated associations between markers of inflammatory status and adiposity (interleukin-6 [IL-6], adiponectin and leptin) and measures of bone phenotype and fractures. The Medical Research Council (MRC) National Survey of Health and Development (NSHD) is a British birth cohort study. Participants (born during the same week in 1946) with complete data on DXA and pQCT parameters, markers of inflammatory status and adiposity, and potential confounders (498 men and 474 women) were included in cross-sectional analyses.

Risk factors for the development of knee osteoarthritis across the lifespan: A systematic review and meta-analysis.

Objective: To identify and quantify risk factors for incident knee osteoarthritis (KOA) across the lifespan.

Methods: This systematic review and meta-analysis identified eligible studies from seven electronic databases and three registries. Longitudinal cohort studies or randomised controlled trials evaluating participants who developed incident symptomatic and/or radiographic KOA were included.

Impact of supervised aerobic exercise training on habitual physical activity in healthy older adults: the Hertfordshire physical activity randomised controlled trial.

Objectives: Physical activity is important for health, but the influence of structured, supervised aerobic exercise sessions on habitual physical activity in healthy older adults is unclear.

Methods: We evaluated habitual physical activity in the Hertfordshire Physical Activity Trial, where healthy older adults were randomised to 36 supervised 1-hour gymnasium sessions on a cycle ergometer at moderate intensity over 12 weeks or to a control group with no intervention. We estimated physical activity energy expenditure (PAEE) and time spent in sedentary behaviour and light and moderate or vigorous physical activity over 7 days at three time points (before, during and immediately after the intervention) with individually calibrated combined heart rate and movement sensing.

Treatment of Osteoporosis and Osteoarthritis in the Oldest Old.

Osteoporosis and osteoarthritis are key diseases of musculoskeletal ageing and are increasing in prevalence and burden with the progressively ageing population worldwide. These conditions are thus particularly common in 'the oldest old', and there are complexities of managing them within the context of extensive multimorbidity, physical and mental disability, and polypharmacy, the rates for all of which are high in this population. In this narrative review, we explore the epidemiology of osteoporosis and osteoarthritis in the oldest old before examining trials and real-world data relating to the pharmacological treatment of these diseases in older adults, including anti-resorptives and bone-forming agents in osteoporosis and symptomatic slow-acting drugs for osteoarthritis, paracetamol, and non-steroidal anti-inflammatory drugs in osteoarthritis, recognising that the oldest old are usually excluded from clinical trials.

Rheumatoid arthritis and subsequent fracture risk: an individual person meta-analysis to update FRAX.

Unlabelled: The relationship between rheumatoid arthritis (RA) and fracture risk was estimated in an international meta-analysis of individual-level data from 29 prospective cohorts. RA was associated with an increased fracture risk in men and women, and these data will be used to update FRAX®.

Introduction: RA is a well-documented risk factor for subsequent fracture that is incorporated into the FRAX algorithm.

The effect of pregnancy vitamin D supplementation on maternal blood pressure: real-world data analysis within the MAVIDOS randomised placebo-controlled trial.

Purpose: Observational studies have suggested negative associations between maternal 25-hydroxyvitamin D (25(OH)D) status and risk of hypertensive disorders of pregnancy [pregnancy-induced hypertension (PIH) and preeclampsia (PET)]. Data from intervention studies are limited. We hypothesised that vitamin D supplementation would lower maternal blood pressure (BP) during pregnancy and reduce the incidence of hypertensive disorders of pregnancy.

Impact of dementia and mild cognitive impairment on bone health in older people.

Mild cognitive impairment, dementia and osteoporosis are common diseases of ageing and, with the increasingly ageing global population, are increasing in prevalence. These conditions are closely associated, with shared risk factors, common underlying biological mechanisms and potential direct causal pathways. In this review, the epidemiological and mechanistic links between mild cognitive impairment, dementia and skeletal health are explored.

Diet quality from mid-life and body composition in older age: findings from a British birth cohort.

We investigated associations between 'healthy dietary pattern' scores, at ages 36, 43, 53 and 60-64 years, and body composition at age 60-64 years among participants from the MRC National Survey of Health and Development (NSHD). Principal component analyses of dietary data (food diaries) at age 60-64 years were used to calculate diet scores (healthy dietary pattern scores) at each age. Higher scores indicated healthier diets (higher consumption of fruit, vegetables and wholegrain bread).

Multimorbidity and risk of adverse outcomes in the Hertfordshire Cohort Study: does sex matter?

Aims: We examined whether admission risk increases at a certain threshold of number of systems medicated or whether any increase confers greater admission risk in either sex in a community-dwelling cohort of older persons in Hertfordshire. This study uses a longitudinal retrospective study design.

Methods: Data from 2997 men and women (aged 59-73 at baseline) were analyzed.

Pregnancy vitamin D supplementation and offspring bone mineral density in childhood follow-up of a randomized controlled trial.

Background: Findings from the Maternal Vitamin D Osteoporosis Study (MAVIDOS) trial demonstrated a positive effect of gestational cholecalciferol supplementation on offspring bone mineral density (BMD) at age 4 y. Demonstrating the persistence of this effect is important to understanding whether maternal vitamin D supplementation could be a useful public health strategy to improving bone health.

Objectives: We investigated whether gestational vitamin D supplementation increases offspring BMD at ages 6-7 y in an exploratory post-hoc analysis of an existing trial.

Intensive physical activity following total hip arthroplasty increased the revision risk after 15 years: a cohort study of 973 patients from the Geneva Arthroplasty Register.

Background And Purpose: Younger recipients of total hip arthroplasty (THA) highly prioritize returning to preoperative levels of physical activity (PA). Surgeons have tended to give cautious advice concerning high-impact sports participation, but there have been few long-term studies. The purpose of our study was to investigate the risk of revision arthroplasty in relation to postoperative PA levels.

Multimorbidity and risk of falls, fractures, and joint replacements over two decades: Findings from the Hertfordshire Cohort Study.

Aim: To examine the relationship between level of morbidity burden and long-term risk of fractures, falls, and joint replacements in the community-dwelling participants of the Hertfordshire Cohort Study.

Methods: Data were analyzed from 2997 individuals (age 59-73 at baseline). Outcomes (fractures, falls, and lower limb joint replacements) were identified using ICD-10 and OPCS-4 codes from Hospital Episode Statistics data, available from baseline (1998-2004) until December 2018.
