. We found a consistent positive association between ALS aggravation and OM (1.17, 95% confidence intervals [CI], 1.11, 1.24 per standard deviation [SD] increase) and a negative association with soil (RR = 0.91, 95% CI, 0.86, 0.97).

Our findings suggest that PM
composition may influence its effect on ALS. We found that annual increases in county-level particulate OM may be associated with disease aggravation in ALS, even at PM
levels below current standards.

In addition to long-term trends, there are also interannual variations in heat-related mortality that are of interest for efficient planning of health services. Large-scale climate patterns have an important influence on summer weather and therefore constitute important tools to understand and predict the variations in heat-related mortality.
In this article, we propose to model summer heat-related mortality using seven climate indices through a two-stage analysis using data covering the period 1981-2018 in two metropolitan areas of the province of Québec (Canada) Montréal and Québec. In the first stage, heat attributable fractions are estimated through a time series regression design and distributed lag nonlinear specification. We consider different definitions of heat. In the second stage, estimated attributable fractions are predicted using climate index curves through a functional linear regression model.

Results indicate that the Atlantic Multidecadal Oscillation is the best predictor of heat-related mortality in both Montréal and Québec and that it can predict up to 20% of the interannual variability.

We found evidence that one climate index is predictive of summer heat-related mortality. More research is needed with longer time series and in different spatial contexts. The proposed analysis and the results may nonetheless help public health authorities plan for future mortality related to summer heat.

Current risk reduction policies and strategies are informed by existing scientific evidence, which is limited due to the challenges of studying the complex relationship between exposure at work and outside work and health. We define the working life exposome as all occupational and related nonoccupational exposures. The latter includes nonoccupational exposures that may be directly or indirectly influenced by or interact with the working life of the individual in their relation to health. The Exposome Project for Health and Occupational Research aims to advance knowledge on the complex working life exposures in relation to disease beyond the single high exposure-single health outcome paradigm, mapping and relating interrelated exposures to inherent biological pathways, key body functions, and health. This will be achieved by combining (1) large-scale harmonization and pooling of existing European cohorts systematically looking at multiple exposures and diseases, with (2) the collection of new high-resolution external and internal exposure data. Methods and tools to characterize the working life exposome will be developed and applied, including sensors, wearables, a harmonized job exposure matrix (EuroJEM), noninvasive biomonitoring, omics, data mining, and (bio)statistics. The toolbox of developed methods and knowledge will be made available to policy makers, occupational health practitioners, and scientists. Advanced knowledge on working life exposures in relation to NCDs will serve as a basis for evidence-based and cost-effective preventive policies and actions. The toolbox will also enable future scientists to further expand the working life exposome knowledge base.
Spinal fusion surgery is a common and painful musculoskeletal surgery performed in the adolescent population. Despite the known risk for developing chronic postsurgical pain, few perioperative psychosocial interventions have been evaluated in this population, and none have been delivered remotely (via the Internet) to improve accessibility.

The aim of this single-arm pilot study was to evaluate the feasibility and acceptability of the first Internet-based psychological intervention delivered during the perioperative period to adolescents undergoing major spinal fusion surgery and their parents.

Thirteen adolescents (M age=14.3; 69.2% female) scheduled for spine fusion surgery and their parents were provided access to the online psychosocial intervention program. The program included six lessons delivering cognitive-behavioral therapy skills targeting anxiety, sleep, and acute pain management during the month prior to and the month following surgery. Feasibility indicators included recruitment rate, intets. Given favorable feasibility outcomes, an important next step is to evaluate the intervention in a full-scale randomized controlled trial.Vitamin D receptor agonists (VDRAs) are commonly prescribed in chronic kidney disease (CKD). However, their protective effects on bone remain controversial. We performed a systematic review and meta-analysis of randomized controlled trials (RCTs) to evaluate the effect of VDRAs on fracture risk and bone mineral density (BMD) in adult patients with CKD. We searched MEDLINE, EMBASE, CENTRAL, ClinicalTrials.gov, and the WHO's International Clinical Trials Registry Platform databases from inception to June 19, 2021. We included RCTs comparing VDRAs, to placebo or another medication, in adults with CKD requiring or not dialysis. Conference abstracts and trials involving kidney transplant recipients and/or comparing VDRAs to antiresorptive or anabolic bone therapy were excluded. Primary outcome was fracture at any anatomical site. Secondary outcomes were BMD at femoral neck, lumbar spine, and/or total hip. Prespecified subgroup analyses were conducted according to baseline demographics, overall risk of bias, and fo of VDRAs on bone outcomes are thus required. © 2022 The Authors.

Trimethylation of lysine 27 of histone H3 at the cis-regulatory element of Hhex was maintained and that of lysine 4 was reduced during receptor activator of nuclear factor κB ligand (RANKL)-induced osteoclastogenesis, which was associated with a reduction of Hhex expression. Overexpression of Hhex in bone marrow-derived macrophages inhibited, whereas Hhex suppression promoted, RANKL-induced osteoclastogenesis in vitro. Conditional deletion of Hhex in osteoclast-lineage cells promoted osteoclastogenesis and reduced cancellous bone volume in mice, confirming the negative regulatory role of Hhex in osteoclast differentiation. Expression of cyclin-dependent kinase inhibitors such as Cdkn2a and Cdkn1b in osteoclast precursors was negatively regulated by Hhex, and Hhex deletion increased the ratio of cells at the G1 phase of the cell cycle. In conclusion, Hhex is an inhibitor of osteoclast differentiation that is regulated in an epigenetic manner and regulates the cell cycle of osteoclast precursors and the skeletal homeostasis. © 2022 The Authors.

Still, how the complex pathological mechanisms are linked is only sparsely understood. 8-Cyclopentyl-1,3-dimethylxanthine Up to now, the focus has been on the disturbed bone metabolism in developing vascular calcification. However, our group has recently demonstrated that vascular calcification has negative effects on bone formation and mineralization as shown in the bone of normal recipient rats transplanted with the calcified aorta from CKD rats. In the present in vitro study, the hypothesis of a direct crosstalk between the vasculature and bone was examined. Calcified aortas from 5/6 nephrectomized rats and normal aortas from control rats were excised and incubated ex vivo. The calcified aorta secreted large amounts of sclerostin, dickkopf-1 (Dkk1), and activin A. Both normal and calcified aortas secreted frizzle-related protein 4 (SFRP4). Aorta rings were co-incubated with the osteoblast-like cell line UMR-106. The calcified aorta strongly inhibited calcium crystal formation in UMR-106 cells, together with a significant upregulation of the mineralization inhibitors osteopontin and progressive ankylosis protein homolog (ANKH). The strong stimulation of osteopontin was blocked by lithium chloride, indicating involvement of Wnt/β-catenin signaling. The present in vitro study shows detrimental effects of the calcified aorta on bone cell mineralization. These findings support the hypothesis of an active role of the calcified vasculature in the systemic CKD-mineral and bone disorder (CKD-MBD), resulting in a pathological vascular-bone tissue crosstalk. © 2022 The Authors.

The current post hoc analyses describe hip 3D-DXA data for ACTIVExtend (NCT01657162), in which 18 months of ABL followed by 24 months of alendronate (ABL/ALN) increased hip and spine areal BMD (aBMD) and reduced fracture risk versus placebo (PBO) followed by ALN (PBO/ALN). In an ACTIVExtend subgroup (ABL/ALN, n = 204; PBO/ALN, n = 202), hip DXA scans retrospectively underwent 3D modeling via 3D-Shaper software. Changes from baseline in cortical and trabecular compartments were calculated for total hip and hip subregions (femoral neck, trochanter, and shaft). Estimated strength indices comprising cross-sectional moment of iner improves trabecular and cortical 3D-DXA parameters at the hip, as well as strength indices of hip subregions, with greater increases with ABL/ALN versus PBO/ALN. © 2022 Radius Health, Inc.
