Psychiatric morbidity among people aged 85+ in 1987. A follow-up study at two and a half years: Associations with changes in psychiatric morbidity

This article reports findings from a longitudinal survey of very elderly people living at home in London. The research aimed to identify social, psychological and physical characteristics associated with positive ageing and successful survival in the community in later life and its converse—negative ageing—as well as the associated policy implications. Associations with psychiatric morbidity, measured using the General Health Questionnaire, among sample members without cognitive impairment between the baseline interviews in 1987 and at follow-up, two and a half years later in 1990, are reported. Twenty-five per cent of survivors scored over the threshold of the GHQ in 1987 and 30% scored over the threshold in 1990. Half of those with a score over the threshold in 1990 also scored over the threshold in 1987. Hierarchical regression (using residualized change analysis) was used to estimate the effects of the independent variables on changes in psychiatric morbidity. The most significant predictor of psychiatric morbidity (GHQ score) in 1990 was baseline GHQ score, followed by health and functional status scores. Health and functional status were also the strongest predictors of baseline (1987) GHQ scores. The uniqueness of the study lies in the collection of follow-up data on a sample of very elderly people, given that most surveys are corss-sectional and contain too few people aged 85+ to merit separate analysis. It contributes to the small body of literature on outcome of depression. The lack of consistent associations with recovery from psychiatric morbidity in the literature enhances the importance of studies aiming to identify factors associated with different outcomes.     

Demographic and psychosocial features of participants in bondage and discipline, "sadomasochism" or dominance and submission (BDSM): data from a national survey

IntroductionPeople with sexual interests in bondage and discipline, “sadomasochism” or dominance and submission (BDSM) have been seen by many professionals as damaged or dangerous.AimTo examine sexual behavior correlates of involvement in BDSM and test the hypothesis that BDSM is practiced by people with a history of sexual coercion, sexual difficulties, and/or psychological problems.MethodsIn Australia in 2001–2002, a representative sample of 19,307 respondents aged 16–59 years was interviewed by telephone. Weighted data analysis used univariate logistic regression.Main Outcome MeasuresSelf-reported demographic and psychosocial factors; sexual behavior and identity; sexual difficulties.ResultsIn total, 1.8% of sexually active people (2.2% of men, 1.3% of women) said they had been involved in BDSM in the previous year. This was more common among gay/lesbian and bisexual people. People who had engaged in BDSM were more likely to have experienced oral sex and/or anal sex, to have had more than one partner in the past year, to have had sex with someone other than their regular partner, and to have: taken part in phone sex, visited an Internet sex site, viewed an X-rated (pornographic) film or video, used a sex toy, had group sex, or taken part in manual stimulation of the anus, fisting or rimming. However, they were no more likely to have been coerced into sexual activity, and were not significantly more likely to be unhappy or anxious—indeed, men who had engaged in BDSM scored significantly lower on a scale of psychological distress than other men. Engagement in BDSM was not significantly related to any sexual difficulties.ConclusionOur findings support the idea that BDSM is simply a sexual interest or subculture attractive to a minority, and for most participants not a pathological symptom of past abuse or difficulty with “normal” sex.

Predicting fractures in an international cohort using risk factor algorithms without BMD

Clinical risk factors are associated with increased probability of fracture in postmenopausal women. We sought to compare prediction models using self‐reported clinical risk factors, excluding BMD, to predict incident fracture among postmenopausal women. The GLOW study enrolled women aged 55 years or older from 723 primary‐care practices in 10 countries. The population comprised 19,586 women aged 60 years or older who were not receiving antiosteoporosis medication and were followed annually for 2 years. Self‐administered questionnaires were used to collect data on characteristics, fracture risk factors, previous fractures, and health status. The main outcome measure compares the C index for models using the WHO Fracture Risk (FRAX), the Garvan Fracture Risk Calculator (FRC), and a simple model using age and prior fracture. Over 2 years, 880 women reported incident fractures including 69 hip fractures, 468 “major fractures” (as defined by FRAX), and 583 “osteoporotic fractures” (as defined by FRC). Using baseline clinical risk factors, both FRAX and FRC showed a moderate ability to correctly order hip fracture times (C index for hip fracture 0.78 and 0.76, respectively). C indices for “major” and “osteoporotic” fractures showed lower values, at 0.61 and 0.64. Neither algorithm was better than the model based on age + fracture history alone (C index for hip fracture 0.78). In conclusion, estimation of fracture risk in an international primary‐care population of postmenopausal women can be made using clinical risk factors alone without BMD. However, more sophisticated models incorporating multiple clinical risk factors including falls were not superior to more parsimonious models in predicting future fracture in this population. © 2011 American Society for Bone and Mineral Research     

Prospective analysis of adverse events in surgical treatment of degenerative spondylolisthesis

Background contextSurgical adverse event (AE) monitoring is imprecise, of uncertain validity, and tends toward underreporting. Reports focus on specific procedures rather than outcomes in the context of presenting diagnosis. Specific intraoperative (intraop) or postoperative (postop) AEs that may be independently associated with degenerative spondylolisthesis (DS) have never been reported.PurposeThe primary purpose was to assess the AE profile of surgically treated patients with L4–L5 DS. The secondary goal was to identify potential risk factors that correlate with those AEs.Study design/settingProspective cohort and academic quaternary spine center.Patient sampleNinety-two patients with L4–L5 DS were treated surgically, discharged from Vancouver General Hospital between January 1, 2009 and December 31, 2010.Outcome measuresIncidence rates and odds ratios.MethodsProspective AE data were analyzed using univariate analyses, forward selection regression models, and Spearman correlation coefficients. Results were compared with outcomes reported in the Spine Patient Outcomes Research Trial.ResultsNo AEs were seen in 57.6% of patients, one AE in 17.4%, and two or more AEs in 17.4%. Dural tears (6.5%) and intraop bone-implant interface failure requiring revision (3.3%) were the most common intraop AEs. Postoperatively, the most frequent AEs were urinary tract infection (10.9%), delirium (5.4%), neuropathic pain (4.4%), deep wound infection (3.3%), and superficial wound infection (3.3%). The odds of an intraop AE increased by 9% (95% confidence interval [CI] 1–18) per year of age at admission. Adjusted Charlson comorbidity index (CCI) did not correlate with number of AEs experienced. The odds of postop delirium correlated with CCI (odds ratio [OR] 3.39, 95% CI 1.12–10.24) and dural tear (OR 35.84, 95% CI 1.72–747.45). Length of stay was statistically significant and was influenced by two or more AEs, CCI, postop loss of correction, cerebrospinal fluid leak, deep wound infection, noninfected wound drainage, and gender.ConclusionsRisk of intraop AEs, but not postop AEs, increased with increasing age. Having multiple comorbidities does not predispose to more AEs. Infections predominate among the postop AEs. Patients at increased risk of delirium or of having an increased length of hospital stay may more easily be predicted. Studies specifically designed to prospectively assess AEs have the potential to more accurately identify postop AE rates.     

Evidence supporting a role of glucocorticoids in short-term bone loss in burned children

Children burned 40% total body surface area suffer acute bone loss. The reason(s) for this is uncertain. In order to determine whether high endogenous glucocorticoid production can contribute to the bone loss, we sequentially studied a total of 14 pediatric burn patients for bone histomorphometry; 7 of these patients and 4 controls were studied for characteristics of corticosteroid-induced bone loss, including decreased osteoblasts and down-regulation of the glucocorticoid receptor in bone. We then studied 4 of the burn patients and three controls for a decrease in markers of osteoblast differentiation, another feature of glucocorticoid toxicity. Bone biopsies were taken from each of the 14 burn patients a mean of 3 weeks post-burn. Histomorphometry was performed on one specimen (n=7) and either glucocorticoid and mineralocorticoid receptor, collagen and alkaline phosphatase expression by RT-PCR (n=7) or marrow stromal cell culture (n=4) on the other. Patients were permitted a maximum of two biopsies for study. One biopsy was obtained intra-operatively from normal subjects during elective iliac crest alveolar bone grafting and compared with burn specimens for glucocorticoid receptors and marrow stromal cell culture. A 24-h urine specimen was obtained for free cortisol (n=7). Histomorphometry revealed low osteoblast and osteoid surfaces and few detectable osteoblasts. Resorptive surfaces were also reduced. Glucocorticoid receptor mRNA (GR) was not decreased; however, there was a trend toward inverse relationships between urine free cortisol and GR and type-1 collagen mRNA, r=–0.61 and –0.64, respectively, and a significantly lower mRNA for type-1 collagen in bone in burn vs control patients by the median test, ²=7.6 (p<0.01). Markers of osteoblast differentiation, core-binding factor (cbf)a1, bone morphogenetic protein (BMP)-2, type-I collagen, and alkaline phosphatase were reduced in burn cell cultures compared with controls (p<0.05). The eightfold elevation of urinary free cortisol excretion, low osteoblast number, decreased resorptive surface, and reduced markers of osteoblast differentiation are all consistent with an acute glucocorticoid effect on bone.     

Previous fractures at multiple sites increase the risk for subsequent fractures: the Global Longitudinal Study of Osteoporosis in Women

Previous fractures of the hip, spine, or wrist are well-recognized predictors of future fracture, but the role of other fracture sites is less clear. We sought to assess the relationship between prior fracture at 10 skeletal locations and incident fracture. The Global Longitudinal Study of Osteoporosis in Women (GLOW) is an observational cohort study being conducted in 17 physician practices in 10 countries. Women aged ≥55 years answered questionnaires at baseline and at 1 and/or 2 years (fractures in previous year). Of 60,393 women enrolled, follow-up data were available for 51,762. Of these, 17.6%, 4.0%, and 1.6% had suffered 1, 2, or ≥3 fractures, respectively, since age 45 years. During the first 2 years of follow-up, 3149 women suffered 3683 incident fractures. Compared with women with no previous fractures, women with 1, 2, or ≥3 prior fractures were 1.8-, 3.0-, and 4.8-fold more likely to have any incident fracture; those with ≥3 prior fractures were 9.1-fold more likely to sustain a new vertebral fracture. Nine of 10 prior fracture locations were associated with an incident fracture. The strongest predictors of incident spine and hip fractures were prior spine fracture (hazard ratio [HR] = 7.3) and hip (HR = 3.5). Prior rib fractures were associated with a 2.3-fold risk of subsequent vertebral fracture, and previous upper leg fracture predicted a 2.2-fold increased risk of hip fracture. Women with a history of ankle fracture were at 1.8-fold risk of future fracture of a weight-bearing bone. Our findings suggest that a broad range of prior fracture sites are associated with an increased risk of incident fractures, with important implications for clinical assessments and risk model development.     

Creating an Academy of Medical Educators: How and Where to Start

Background

While most faculty members want to improve as teachers, they neither know where their educational strengths and weaknesses lie nor where or how to begin to effect a change in their teaching abilities. The lack of actionable, directed and specific feedback, and sensible and sensitive metrics to assess performance and improvement complicates the attainment of educational excellence.

Purpose

The purpose of this article was to outline a series of specific steps that medical education programs can take to enhance the quality of teaching, promote teaching excellence, elevate the status and value of medical educators, and stimulate the creation of innovative teaching programs and curricula.

Methods

To achieve these goals at the Hospital for Special Surgery, the Academy of Rheumatology Medical Educators was formed. The academy had the following goals: (1) create within our institution a mission which advances and supports educators, (2) establish a membership composed of distinguished educators, (3) create a formal organizational structure with designated leadership, (4) dedicate resources that fund mission-related initiatives and research, and (5) establish a plan for promoting teachers as well as enhancing and advancing educational scholarship.

Results

The Hospital for Special Surgery Academy of Rheumatology Medical Educators was recently formed to address these goals by promoting teaching and learning of musculoskeletal skills in an environment that is supportive to educators and trainees and provides much needed resources for teachers.

Summary

The development of a pilot academy of medical educators represents one of the high-priority goals of those institutions that wish to elevate and enrich their teaching through a structured, proven approach.     

Postmenopausal osteoporosis treatment with antiresorptives: effects of discontinuation or long-term continuation on bone turnover and fracture risk--a perspective

Osteoporosis may be a lifelong condition. Robust data regarding the efficacy and safety of both long-term osteoporosis therapy and therapy discontinuation are therefore important. A paucity of clinical trial data regarding the long-term antifracture efficacy of osteoporosis therapies necessitates the use of surrogate endpoints in discussions surrounding long-term use and/or discontinuation. Long-term treatment (beyond 3-4 years) may produce further increases in bone mineral density (BMD) or BMD stability, depending on the specific treatment and the skeletal site. Bisphosphonates, when discontinued, are associated with a prolonged reduction in bone turnover markers (BTMs), with a very gradual increase to pretreatment levels within 3 to 60 months of treatment cessation, depending on the bisphosphonate used and the prior duration of therapy. In contrast, with nonbisphosphonate antiresorptive agents, such as estrogen and denosumab, BTMs rebound to above pretreatment values within months of discontinuation. The pattern of BTM change is generally mirrored by a more or less rapid decrease in BMD. Although the prolonged effect of some bisphosphonates on BTMs and BMD may contribute to residual benefit on bone strength, it may also raise safety concerns. Adequately powered postdiscontinuation fracture studies and conclusive evidence on maintenance or loss of fracture benefit is lacking for bisphosphonates. Similarly, the effects of rapid reversal of bone turnover upon discontinuation of denosumab on fracture risk remain unknown. Ideally, studies evaluating the effects of long-term treatment and treatment discontinuation should be designed to provide head-to-head "offset" data between bisphosphonates and nonbisphosphonate antiresorptive agents. In the absence of this, a clinical recommendation for physicians may be to periodically assess the benefits/risks of continuation versus discontinuation versus alternative management strategies.
