Summary The term sarcopenia refers to the loss of muscle mass that occurs with ageing. On the basis of study results showing that muscle mass is only moderately related to functional outcomes, international working groups have proposed that loss of muscle strength or physical function should also be included in the definition. Irrespective of how sarcopenia is defined, both low muscle mass and poor muscle strength are clearly highly prevalent and important risk factors for disability and potentially mortality in individuals as they age. Many chronic diseases, in addition to ageing, could also accelerate decrease of muscle mass and strength, and this effect could be a main underlying mechanism by which chronic diseases cause physical disability. In this Review, we address both age-related and disease-related muscle loss, with a focus on diabetes and obesity but including other disease states, and potential common mechanisms and treatments. Development of treatments for age-related and disease-related muscle loss might improve active life expectancy in older people, and lead to substantial health-care savings and improved quality of life.

Diabetes in the elderly is a growing public health burden. Persons with diabetes are living longer and are vulnerable to the traditional microvascular and macrovascular complications of diabetes but also at increased risk for geriatric syndromes. Peripheral vascular disease, heart disease, and stroke all have a high prevalence among older adults with diabetes. Traditional microvascular complications such as retinopathy, nephropathy, and neuropathy also frequently occur. Unique to this older population is the effect of diabetes on functional status. Older adults with diabetes are also more likely to experience geriatric syndromes such as falls, dementia, depression, and incontinence. Further studies are needed to better characterize those elderly individuals who may be at the highest risk of adverse complications from diabetes.

Residency work hour restrictions in 2003 changed medical student participation in overnight call.The goal is to compare experiences, attitudes, and skills between medical students who did and did not participate in overnight call.Using a retrospective cohort design, all students at one medical school received a survey at the end of their 3rd-year internal medicine clerkship. Students at 3 clerkship sites were required to take overnight call, and students at 2 sites were not.One hundred four of 167 (62%) students participated. Sixty-one of 104 (59%) took overnight call. Overnight call students reported improved team relationships and were able to evaluate more unstable "cross-cover" patients. Students who took overnight call were more likely to state it was worthwhile (58% vs. 34%; p = .034). Overnight call led to fatigue and the perception of interference with didactics.Overnight call within the internal medicine clerkship has positive and negative effects. With new residency work hour restrictions, schools may consider innovative ways to preserve the positive experiences while working to minimize fatigue and interference with learning.

Background: A specialties’ lifestyle is known to be important for specialty selection, but how medical students define this concept is unknown. Purpose: The aim of this article is to determine how 4th-year medical students perceive lifestyle of specialties. Methods: All 4th-year U.S. medical students graduating in 2009 with a military service obligation were invited to participate in an electronic survey. Responses to an open-ended question, “When someone says ‘That specialty has a good lifestyle,’ what does that mean to you?” were classified into themes by a consensus of the authors and then compared to the students’ selected specialty. Results: Response rate for the questionnaire was 46% (369 of 797). Four themes describing lifestyle emerged: “schedule control” (67% of students), “off time” (53%), “financial aspects” (48%), and “work life” (26%). Conclusions: Medical students’ definition of a “good lifestyle” includes four themes, which should be used in future research of the lifestyle factor of specia...

Face-to-face formal evaluation sessions between clerkship directors and faculty can facilitate the collection of trainee performance data and provide frame-of-reference training for faculty.We hypothesized that ambulatory faculty who attended evaluation sessions at least once in an academic year (attendees) would use the Reporter-Interpreter-Manager/Educator (RIME) terminology more appropriately than faculty who did not attend evaluation sessions (non-attendees).Investigators conducted a retrospective cohort study using the narrative assessments of ambulatory internal medicine clerkship students during the 2008-2009 academic year.The study included assessments of 49 clerkship medical students, which comprised 293 individual teacher narratives.Single-teacher written and transcribed verbal comments about student performance were masked and reviewed by a panel of experts who, by consensus, (1) determined whether RIME was used, (2) counted the number of RIME utterances, and (3) assigned a grade based on the comments. Analysis included descriptive statistics and Pearson correlation coefficients.The authors reviewed 293 individual teacher narratives regarding the performance of 49 students. Attendees explicitly used RIME more frequently than non-attendees (69.8 vs. 40.4 %; p0.0001). Grades recommended by attendees correlated more strongly with grades assigned by experts than grades recommended by non-attendees (r = 0.72; 95 % CI (0.65, 0.78) vs. 0.47; 95 % CI (0.26, 0.64); p = 0.005). Grade recommendations from individual attendees and non-attendees each correlated significantly with overall student clerkship clinical performance [r = 0.63; 95 % CI (0.54, 0.71) vs. 0.52 (0.36, 0.66), respectively], although the difference between the groups was not statistically significant (p = 0.21).On an ambulatory clerkship, teachers who attended evaluation sessions used RIME terminology more frequently and provided more accurate grade recommendations than teachers who did not attend. Formal evaluation sessions may provide frame-of-reference training for the RIME framework, a method that improves the validity and reliability of workplace assessment.

Previous studies exploring the relationship of neighborhood characteristics with metabolic conditions have focused on middle-aged adults but none have comprehensively investigated associations in older adults, a potentially vulnerable population. The aim was to explore the relationship of neighborhood characteristics with metabolic conditions in older women.Cross-sectional analysis.We studied 384 women aged 70-79 years, representing the two-thirds least disabled women in the community, enrolled in the Women's Health and Aging Study II at baseline. Neighborhood scores were calculated from census-derived data on median household income, median house value, percent earning interest income, percent completing high school, percent completing college, and percent with managerial or executive occupation. Participants were categorized by quartile of neighborhood score with a higher quartile representing relative neighborhood advantage. Logistic regression models were created to assess the association of neighborhood quartiles to outcomes, adjusting for key covariates.Primary outcomes included metabolic conditions: obesity, diabetes, hypertension, and hyperlipidemia. Secondary outcomes included BMI, HbA1c, blood pressure and lipids.Higher neighborhood quartile score was associated with a lower prevalence of obesity (highest quartile=13.5% versus lowest quartile=36.5%; p0.001 for trend). A lower prevalence of diabetes was also observed in highest (6.3%) versus lowest (14.4%) neighborhood quartiles, but was not significantly different (p= 0.24 for trend). Highest versus lowest neighborhood quartile was associated with lower HbA1c (-0.31%, p=0.02) in unadjusted models. Women in the highest versus lowest neighborhood quartile had lower BMI (-2.01 kg/m2, p=0.001) and higher HDL-cholesterol (+6.09 mg/dL, p=0.01) after accounting for age, race, inflammation, and smoking.Worse neighborhood characteristics are associated with adiposity, hyperglycemia, and low HDL. Further longitudinal studies are needed and can inform future interventions to improve metabolic status in older adults.

Background Clinical guidelines for type 2 diabetes are a resource for providers to manage their patients and may help highlight specific areas in need of further education and training. We sought to determine how often guidelines are used and the relationship to physicians’ diabetes-related knowledge and decision making. Methods Existing users of electronic clinical support tools were invited to complete an online questionnaire. A knowledge score was calculated for five questions related to prevention of diabetes and treatment of its complications. We explored the association of clinical guideline use with diabetes-related knowledge and self-reported decision making using logistic regression models, adjusted for key covariates. Results Of 383 physicians completing the questionnaire, 53% reported using diabetes guidelines routinely. Mean diabetes knowledge score for guideline users (GU) was significantly higher than non-guideline users (NGU) (3.37 ± 0.072 vs. 2.76 ± 0.084; p
