Nutritional status and nutritional treatment are related to outcomes and mortality in older adults with hip fracture

Malnutrition is very prevalent in geriatric patients with hip fracture. Nevertheless, its importance is not fully recognized. The objective of this paper is to review the impact of malnutrition and of nutritional treatment upon outcomes and mortality in older people with hip fracture. We searched the PubMed database for studies evaluating nutritional aspects in people aged 70 years and over with hip fracture. The total number of studies included in the review was 44, which analyzed 26,281 subjects (73.5% women, 83.6 ± 7.2 years old). Older people with hip fracture presented an inadequate nutrient intake for their requirements, which caused deterioration in their already compromised nutritional status. The prevalence of malnutrition was approximately 18.7% using the Mini-Nutritional Assessment (MNA) (large or short form) as a diagnostic tool, but the prevalence was greater (45.7%) if different criteria were used (such as Body Mass Index (BMI), weight loss, or albumin concentration). Low scores in anthropometric indices were associated with a higher prevalence of complications during hospitalization and with a worse functional recovery. Despite improvements in the treatment of geriatric patients with hip fracture, mortality was still unacceptably high (30% within 1 year and up to 40% within 3 years). Malnutrition was associated with an increase in mortality. Nutritional intervention was cost effective and was associated with an improvement in nutritional status and a greater functional recovery. To conclude, in older people, the prevention of malnutrition and an early nutritional intervention can improve recovery following a hip fracture

Epidemiology of hip fracture in Belarus: development of a country-specific FRAX model and its comparison to neighboring country models

Summary Fracture probabilities resulting from the newly generated FRAX model for Belarus based on regional estimates of the hip fracture incidence were compared with FRAX models of neighboring countries. Differences between the country-specific FRAX patterns and the rank orders of fracture probabilities were modest. Objective This paper describes the epidemiology of hip fractures in Belarus that was used to develop the country-specific fracture prediction FRAX® tool and illustrates its features compared to models for the neighboring countries of Poland, Russia, and Lithuania. Methods We carried out a population-based study in a region of Belarus (the city of Mozyr) representing approximately 1.2% of the country’s population. We aimed to identify all hip fractures in 2011–2012 from hospital registers and primary care sources. Age- and sex-specific incidence and national mortality rates were incorporated into a FRAX model for Belarus. Fracture probabilities were compared with those derived from FRAX models in neighboring countries. Results The estimated number of hip fractures nationwide in persons over the age of 50 years for 2015 was 8250 in 2015 and is predicted to increase to 12,918 in 2050. The annual incidence of fragility hip fractures in individuals aged 50 years or more was 24.6/10,000 for women and 14.6/10,000 for men, standardized to the world population. The comparison with FRAX models in neighboring countries showed that hip fracture probabilities in men and women in Belarus were similar to those in Poland, Russia, and Lithuania. The difference in incidence rates between the surveys including or excluding data from primary care suggested that 29.1% of patients sustaining a hip fracture were not hospitalized and, therefore, did not receive specialized medical care. Conclusion A substantial proportion of hip fractures in Belarus does not come to hospital attention. The FRAX model should enhance accuracy of determining fracture probability among the Belarus population and help guide decisions about treatment

Development and application of a Japanese model of the WHO fracture risk assessment tool (FRAX™)

SUMMARY: The present study estimated the 10-year probability using the Japanese version of WHO fracture risk assessment tool (FRAX) in order to determine fracture probabilities that correspond to intervention thresholds currently used in Japan and to resolve some issues for its use in Japan. INTRODUCTION: The objective of the present study was to evaluate a Japanese version of the WHO fracture risk assessment (FRAX) tool to compute 10-year probabilities of osteoporotic fracture in Japanese men and women. Since lumbar spine bone mineral density (BMD) is used preferentially as a site for assessment, and densitometers use Japanese reference data, a second aim was to investigate the suitability and impact of this practice in Japan. METHODS: Fracture probabilities were computed from published data on the fracture and death hazards in Japan. Probabilities took account of age, sex, the presence of clinical risk factors and femoral neck BMD. Fracture probabilities were determined that were equivalent to intervention thresholds currently used in Japan. The difference between T-scores derived from international reference data and that using Japanese-specific normal ranges was estimated from published sources. The gradient of risk of BMD for fracture in Japan was compared to that for BMD at the lumbar spine in the Hiroshima cohort. RESULTS: The 10-year probabilities of a major osteoporosis-related fracture that corresponded to current intervention thresholds ranged from approximately 5% at the age of 50 years to more than 20% at the age of 80 years. The use of femoral neck BMD predicts fracture as well as or better than BMD tests at the lumbar spine. There were small differences in T-scores between those used for the model and those derived from a Japanese reference population. CONCLUSIONS: The FRAX mark tool has been used to determine possible thresholds for therapeutic intervention, based on equivalence of risk with current guidelines. The approach will need to be supported by appropriate health economic analyses. Femoral neck BMD is suitable for the prediction of fracture risk among Japanese. However, when applying the FRAX model to Japan, T-scores and Z-scores should be converted to those derived from the international reference

Remaining lifetime and absolute 10-year probabilities of osteoporotic fracture in Swiss men and women

Summary: Remaining lifetime and absolute 10-year probabilities for osteoporotic fractures were determined by gender, age, and BMD values. Remaining lifetime probability at age 50years was 20.2% in men and 51.3% in women and increased with advancing age and decreasing BMD. The study validates the elements required to populate a Swiss-specific FRAX® model. Introduction: Switzerland belongs to high-risk countries for osteoporosis. Based on demographic projections, burden will still increase. We assessed remaining lifetime and absolute 10-year probabilities for osteoporotic fractures by gender, age and BMD in order to populate FRAX® algorithm for Switzerland. Methods: Osteoporotic fracture incidence was determined from national epidemiological data for hospitalised fractured patients from the Swiss Federal Office of Statistics in 2000 and results of a prospective Swiss cohort with almost 5,000 fractured patients in 2006. Validated BMD-associated fracture risk was used together with national death incidence and risk tables to determine remaining lifetime and absolute 10-year fracture probabilities for hip and major osteoporotic (hip, spine, distal radius, proximal humerus) fractures. Results: Major osteoporotic fractures incidence was 773 and 2,078 per 100,000 men and women aged 50 and older. Corresponding remaining lifetime probabilities at age 50 were 20.2% and 51.3%. Hospitalisation for clinical spine, distal radius, and proximal humerus fractures reached 25%, 30% and 50%, respectively. Absolute 10-year probability of osteoporotic fracture increased with advancing age and decreasing BMD and was higher in women than in men. Conclusion: This study validates the elements required to populate a Swiss-specific FRAX® model, a country at highest risk for osteoporotic fracture

FRAX® assessment of osteoporotic fracture probability in Switzerland

Summary: A Swiss-specific FRAX® model was developed. Patient profiles at increased probability of fracture beyond currently accepted reimbursement thresholds for bone mineral density (BMD) measurement by dual X-ray absorptiometry (DXA), and osteoporosis treatment were identified. Introduction: This study aimed to determine which constellations of clinical risk factors, alone, or combined with BMD measurement by DXA, contribute to improved identification of Swiss patients with increased probability of fracture. Methods: The 10-year probability of hip and any major osteoporotic fracture was computed for both sexes, based on Swiss epidemiological data, integrating fracture risk and death hazard, in relation to validated clinical risk factors, with and without BMD values. Results: Fracture probability increased with age, lower body mass index (BMI), decreasing BMD T-score, and all clinical risk factors used alone or combined. Several constellations of risk factor profiles were identified, indicating identical or higher absolute fracture probability than risk factors currently accepted for DXA reimbursement in Switzerland. With identical sex, age and BMI, subjects with parental history of hip fracture had as high a probability of any major osteoporotic fracture as patients on oral glucocorticoids or with a prevalent fragility fracture. The presence of additional risk factors further increased fracture probability. Conclusions: The customised FRAX® model indicates that a shift from the current DXA-based intervention paradigm, toward a fracture risk continuum based on the 10-year probability of any major osteoporotic fracture may improve identification of patients at increased fracture ris

Reducing Stigma toward the Transgender Community: An Evaluation of a Humanizing and Perspective-Taking Intervention

Transgender (TG) individuals, or those whose gender identities, expressions and/or behaviors differ from their biological sex (Kirk & Kulkarni, 2006) feel there is a pervasive pattern of discrimination and prejudice directed toward them (Lombardi et al., 2001). In comparison to their heterosexual peers, LGBT youth and emerging adults are at increased risk for a host of adverse outcomes including: suicide, depression, harassment, and victimization (IOM, 2011). Stigma has been characterized as encompassing several components: labeling, making an association between the label and a negative stereotype, separating those who are different as an “out-group” and discriminating. In a recent analysis of the transgender experience, Hill (2002) described three key constructs that can be used to understand negative emotions and behaviors toward transgender individuals: transphobia – an emotional disgust toward gender non-conforming individuals; genderism – a belief that gender non-conforming individuals are pathological or disordered; gender bashing – assault or harassment of gender non-conforming individuals. Recent work on minority stress posits a distal-proximal model of stress in which a person identifies with and makes proximal, distal social attitudes that can have negative effects on their psychological well-being (Meyer, 2003). Thus, stigmatized attitudes and behaviors not only have the potential to contribute to violence or discriminatory behavior but also have a direct impact on the psychological health of the target individual. Thus, the question of how to change negative attitudes and behaviors toward TG individuals is paramount. Researchers have sought to develop interventions aimed at reducing stigma with three basic strategies identified: protest, education and contact (Corrigan & Penn, 1999). However, to date only two such strategies have garnered empirical support: contact and education. In relation to mental illness, education strategies have received limited support (Holmes et al., 1999; see Luty et al., 2007 for an exception). In contrast, contact-based interventions yield the most dramatic changes in attitudes and behaviors; contact involving media depictions have also been demonstrated to yield positive attitude change. Comparing traditional diagnosis-centered teaching about mental illness to a humanizing approach that required students to write a first-person narrative about suffering from a mental illness, Mann and Himelein (2008) found that attitudes changed only when students were required to adopt the perspective of a mentally ill individual. In their recent meta-analysis, Pettigrew and Tropp (2006) demonstrated that contact reduces prejudice and is particularly effective when it occurs under favorable conditions (e.g., conditions of equality, cooperation, and institutional support). While a wealth of research has supported the contact hypothesis related to changing negative attitudes toward ethnic minorities, the mentally ill, the homeless, gays/lesbians and other stigmatized groups, there have been a limited number of studies evaluating associations between contact and attitudes toward the TG community (Harvey, 2002; Hill & Willoughby, 2005) and no controlled studies to evaluate the efficacy of such methods. The current study extends work evaluating anti-stigma interventions to the TG community and seeks to evaluate whether attitude change will differ between participants receiving basic education about the transgender community and those who are educated about TG through media depictions of TG families and are asked to engage in a perspective-taking task. We hypothesize that participants in the humanizing condition who view a documentary and write a first-person narrative of transgender experiences will show a more significant change in transphobia, genderist attitudes and desire for social distance across time relative to participants in the education-only condition signaling less stigmatized and prejudicial attitudes at post-test. Hodson (2011) recently examined the existing contact literature and found that, consistent with Pettigrew’s (1998) focus on individual differences, intergroup contact was effective (and perhaps even more effective) among individuals who were intolerant and cognitively rigid. Religious fundamentalism has been associated with anti-homosexual sentiment (Fulton et al., 1999). Whether religiosity is similarly associated with negative attitudes toward TG individuals will be explored. Whether religiosity and prior contact with the LGBTQ community will moderate intervention outcomes will also be explored
