The important trace elements, copper and selenium, have diverse effects on human health. As well as other important roles in living tissues, these trace elements are toxic at high levels but are key constituents of various enzymes and proteins essential for maintaining physiological health. However, links between dietary intakes of these elements, particularly copper, and bone mineral density (BMD) in humans remain uncertain.

Introduction: We conducted a systematic review to evaluate the quality and extent of evidence on associations between personality disorders (PDs) and musculoskeletal disorders (MSDs) in population-based studies, since these disorders are leading causes of disease burden worldwide.

Methods: A search strategy of published, peer-reviewed and gray literature was developed in consultation with a liaison librarian and implemented for Embase, CINAHL Complete, Medline Complete, and PsycINFO via the EBSCOhost platform from 1990 to the present and CORDIS and ProQuest Dissertations & Theses Global, respectively. The inclusion criteria were as follows: I) general population participants aged ≥15 years; II) self-report, probable PD based on positive screen, or threshold PD according to the DSM-IV/5 (groupings: any, Clusters A/B/C, specific PD) or ICD-10/11; III) MSDs identified by self-report or ICD criteria (arthritis, back/neck conditions, fibromyalgia, osteopenia/osteoporosis) and III) cohort, case-control, and cross-sectional study designs.

Article Synopsis
  • - The study explores how social determinants, like socioeconomic status (SES), marital status, and perceived social support, relate to cognitive function in men without dementia, using data from the Geelong Osteoporosis Study (n=536).
  • - Results indicate that higher SES, being in a relationship, and having strong social support from significant others and friends correlate with improved cognitive performance across various cognitive tasks.
  • - The findings suggest a need for further research to understand how social factors impact cognitive health, aiming to develop strategies for prevention and enhancement of cognitive function.
