Abstract Context Diabetes mellitus (DM) is associated with an increased risk of fracture, but it is not clear which diabetes and nondiabetes risk factors may be most important. Objective The aim of the study was to evaluate risk factors for incident major osteoporotic fractures (MOFs) of the hip, wrist, and humerus in African American (AA), Hispanic (HIS), and Caucasian (CA) subjects with DM. Methods This was a retrospective cohort study of 18 210 subjects with DM (7298 CA, 7009 AA and 3903 HIS) at least 40 years of age, being followed at a large healthcare system in Philadelphia, Pennsylvania. Results In a global model in CA with DM, MOF were associated with dementia (HR 4.16; 95% CI, 2.13-8.12), OSA (HR 3.35; 95% CI, 1.78-6.29), COPD (HR 2.43; 95% CI, 1.51-3.92), and diabetic neuropathy (HR 2.52; 95% CI, 1.41-4.50). In AA, MOF were associated with prior MOF (HR 13.67; 95% CI, 5.48-34.1), dementia (HR 3.10; 95% CI, 1.07-8.98), glomerular filtration rate (GFR) less than 45 (HR 2.05; 95% CI, 1.11-3.79), thiazide use (HR 0.54; 95% CI, 0.31-0.93), metformin use (HR 0.59; 95% CI, 0.36-0.97), and chronic steroid use (HR 5.03; 95% CI, 1.51-16.7). In HIS, liver disease (HR 3.06; 95% CI, 1.38-6.79) and insulin use (HR 2.93; 95% CI, 1.76-4.87) were associated with MOF. Conclusion In patients with diabetes, the risk of fracture is related to both diabetes-specific variables and comorbid conditions, but these relationships vary by race/ethnicity.

Abstract Context Diabetes mellitus (DM) has been associated with a 60% to 90% increased risk of fracture but few studies have been performed in African American and Hispanic subjects. Objective The aim of the present study was to quantify the risk of incident major osteoporotic fractures (MOFs) of the hip, wrist, and humerus in African Americans, Hispanics, and Caucasians with DM compared with those with hypertension (HTN). Methods We performed a retrospective cohort study of 19,153 subjects with DM (7618 Caucasians, 7456 African Americans, and 4079 Hispanics) and 26,217 with HTN (15,138 Caucasians, 8301 African Americans, and 2778 Hispanics) aged ≥40 years, treated at a large health care system in Philadelphia, Pennsylvania. All information about the subjects was obtained from electronic health records. Results The unadjusted MOF rates for each race/ethnicity were similar among those with DM and those with HTN (Caucasians, 1.85% vs 1.84%; African Americans, 1.07% vs 1.29%; and Hispanics, 1.69% vs 1.33%; P = NS for all). However, the MOF rates were higher for Caucasians and Hispanics with DM than for African Americans with DM (P < 0.01). In a multivariable model controlled for age, body mass index, sex, and previous MOF, DM was a statistically significant predictor of MOFs only for Caucasians and Hispanics [hazard ratio (HR), 1.23; 95% CI, 1.02 to 1.48; P = 0.026] but not for African Americans (HR, 0.92; 95% CI, 0.68 to 1.23; P = 0.56). Conclusions Hispanics had a DM-related fracture risk similar to that of Caucasians, but AAs did not have an additional fracture risk conferred by DM.

Background: Extra-corporeal membrane oxygenation (ECMO) is increasingly being used as a life-saving bypass technique for patients whose acute cardiopulmonary failure is potentially reversible and refractory to conventional care. Prognostic data for ECMO among diverse patients are limited. The purpose of this study was to evaluate the association between age (≥ 65 vs. <65 years) and 1-year mortality after ECMO, adjusted for confounders. Methods: This was a retrospective cohort analysis of 131 consecutive adult patients (28% ≥65 years old, 26% racial/ethnic minority, 38% female) enrolled in an ECMO database who received veno-arterial ECMO at an academic medical center between 2004-2013. Demographics, comorbid conditions, admission characteristics, and mortality status at 1 year were obtained from the hospital clinical information system, updated monthly with Social Security Death Index data. Univariate and multivariate adjusted Cox proportional hazard analyses were conducted to evaluate the associations between age strata and post-ECMO mortality. Results: The 1-year mortality rate post-ECMO was 56% (n=73). Age ≥ 65 vs. <65 was significantly associated with increased mortality (HR=1.8; 95% CI=1.1-2.9); the association was attenuated and did not retain statistical significance after adjustment for comorbid conditions (HR=1.4; 95% CI=0.8-2.5). Figure 1 illustrates mortality risk by age strata adjusted for: a) demographics (race/ethnicity and sex) and b) demographics and comorbid conditions. Race/ethnicity and sex were not significantly associated with 1-year mortality. Significant predictors of mortality included: Medicaid vs. other health insurance status, history of coronary artery bypass graft surgery, peripheral vascular disease, renal failure, dialysis, and shock (p<0.05). Conclusion: Older age (≥65) was not independently associated with 1-year mortality among ECMO patients, but may indicate higher comorbidity, which was associated with increased risk of mortality in the year following ECMO.

The Relationship

There is a large literature on the relationship between obesity and bone. What we can conclude from this review is that the increase in body weight causes an increase in BMD, both for a mechanical effect and for the greater amount of estrogens present in the adipose tissue. Nevertheless, despite an apparent strengthening of the bone witnessed by the increased BMD, the risk of fracture is higher. The greater risk of fracture in the obese subject is due to various factors, which are carefully analyzed by the Authors. These factors can be divided into metabolic factors and increased risk of falls. Fractures have an atypical distribution in the obese, with a lower incidence of typical osteoporotic fractures, such as those of hip, spine and wrist, and an increase in fractures of the ankle, upper leg, and humerus. In children, the distribution is different, but it is not the same in obese and normal-weight children. Specifically, the fractures of the lower limb are much more frequent in obese children. Sarcopenic obesity plays an important role. The authors also review the available literature regarding the effects of high-fat diet, weight loss and bariatric surgery.

Patients With Diabetes

Patients with diabetes mellitus are at an increased risk of bone fractures. Several groups of effective antidiabetic drugs are available, which are very often given in combination. The effects of these medications on bone metabolism and fracture risk must not be neglected. Commonly used antidiabetic drugs might have a positive, neutral or negative impact on skeletal health. Increased risk of fracture has been identified with use of thiazolidinediones, most definitively in women. Also treatment with sulfonylureas can have adverse effects on bone. One consequence of these findings has been greater attention to fracture outcomes in trails of new diabetes medication (incretins and SGLT-2 inhibitors). The effect of insulin on bone is discussed and the risk of fractures in patients using insulin seems to be unrelated to insulin as itself. The aim of the review is to summarize effects of antidiabetic treatment on bone – bone mineral density, fractures and bone turnover markers. The authors also try to recommend a strategy how to treat patients with diabetes mellitus regarding the risk of osteoporotic fractures. In this review the problem of how to treat osteoporosis in patient with diabetes is also discussed.

Objective: The aim of the study was to determine whether heart failure is associated with an increased risk of major osteoporotic fractures that is independent of bone mineral density (BMD). Methods: We conducted a population-based cohort study in Manitoba, Canada, by linking a clinical registry of all adults 50 yr of age and older who underwent initial BMD testing from 1998–2009 with administrative databases. We collected osteoporosis risk factors, comorbidities, medications, and BMD results. Validated algorithms identified recent-onset heart failure before the BMD test and new fractures after. The main outcome was time to major osteoporotic fractures (i.e. clinical vertebrae, distal forearm, humerus, and hip), and multivariable proportional hazards models were used for analyses. Results: The cohort consisted of 45,509 adults; 1,841 (4%) had recent-onset heart failure. Subjects with heart failure were significantly (P &lt; 0.001) older (74 vs. 66 yr) and had more previous fractures (21 vs. 13%) and lower total hip BMD [T-score, −1.3 (sd 1.3) vs. −0.9 (sd 1.2)] than those without. There were 2703 incident fractures over the 5-yr observation. Overall, 10% of heart failure subjects had incident major fractures compared with 5% of those without [unadjusted hazard ratio (HR), 2.45; 95% confidence interval (CI), 2.11–2.85]. Adjustment for osteoporosis risk factors, comorbidities, and medications attenuated but did not eliminate this association (HR, 1.33; 95% CI, 1.11–1.60), nor did further adjustment for total hip BMD (HR, 1.28; 95% CI, 1.06–1.53). Conclusions: Heart failure is associated with a 30% increase in major fractures that is independent of traditional risk factors and BMD, and it also identifies a high-risk population that may benefit from increased screening and treatment for osteoporosis.

• Objective To examine the association between (1) comorbid conditions related to diabetes mellitus, clinical findings on arrival at the hospital, and characteristics of the myocardial infarction and (2) risk of heart failure, recurrent myocardial infarction, and mortality in the year after myocardial infarction in elderly 30-day survivors of myocardial infarction who had non–insulin- or insulin-treated diabetes. • Methods Medical records for June 1, 1992, through February 28, 1993, of Medicare beneficiaries (n = 1698), 65 years or older, hospitalized for acute myocardial infarction in Connecticut were reviewed by trained abstractors. • Results One year after myocardial infarction, elderly patients with non–insulin- and insulin-treated diabetes mellitus had significantly greater risk for readmission for heart failure and recurrent myocardial infarction than did patients without diabetes mellitus, and risk was greater in patients treated with insulin than in patients not treated with insulin. Diabetes mellitus, comorbid conditions related to diabetes mellitus, clinical findings on arrival, and characteristics of the myocardial infarction, specifically measures of ventricular function, were important predictors of these outcomes. Mortality was greater in patients not treated with insulin than in patients treated with insulin; the increased risk was mostly due to comorbid conditions related to diabetes mellitus and poorer ventricular function. • Conclusions Risk of heart failure, recurrent myocardial infarction, and mortality is elevated in elderly patients who have non–insulin- or insulin-treated diabetes mellitus. Comorbid conditions related to diabetes mellitus and ventricular function at the time of the index myocardial infarction are important contributors to poorer outcomes in patients with diabetes mellitus.

Abstract Primary brain tumors account for ~1% of new cancer cases and ~2% of cancer deaths in the United States; however, they are the most commonly occurring solid tumors in children. These tumors are very heterogeneous and can be broadly classified into malignant and benign (or non-malignant), and specific histologies vary in frequency by age, sex, and race/ethnicity. Epidemiological studies have explored numerous potential risk factors, and thus far the only validated associations for brain tumors are ionizing radiation (which increases risk in both adults and children) and history of allergies (which decreases risk in adults). Studies of genetic risk factors have identified 32 germline variants associated with increased risk for these tumors in adults (25 in glioma, 2 in meningioma, 3 in pituitary adenoma, and 2 in primary CNS lymphoma), and further studies are currently under way for other histologic subtypes, as well as for various childhood brain tumors. While identifying risk factors for these tumors is difficult due to their rarity, many existing datasets can be leveraged for future discoveries in multi-institutional collaborations. Many institutions are continuing to develop large clinical databases including pre-diagnostic risk factor data, and developments in molecular characterization of tumor subtypes continue to allow for investigation of more refined phenotypes. Key Point 1. Brain tumors are a heterogeneous group of tumors that vary significantly in incidence by age, sex, and race/ethnicity.2. The only well-validated risk factors for brain tumors are ionizing radiation (which increases risk in adults and children) and history of allergies (which decreases risk).3. Genome-wide association studies have identified 32 histology-specific inherited genetic variants associated with increased risk of these tumors.

e19627 Background: Hormonal therapy with aromatase inhibitors (AI) or tamoxifen (TAM) is standard of care for hormone receptor positive breast cancer and DCIS. Fractures are a complication of treatment with AI due to accelerated bone loss. Risk factors for fracture in patients on hormonal therapy (HT) for breast cancer and DCIS are poorly defined. Methods: All 71 patients with breast cancer or DCIS seen in the bone and mineral clinic of our institution from 2000 to 2010 were analyzed. Data on demographics, pathology, type and duration of HT, bone mineral density studies (BMD), number and site of fractures were collected. Statistical analysis: t test, chi square test and Fisher’s exact test for categorical data. Results: The age of the patients ranged 40 to 97 years. 65 patients had ER positive breast cancer, 6 patients had DCIS. 9 patients had fractures.41 patients were on an AI alone, 8 were on TAM alone and 14 were on both sequentially. Fractures involved: vertebral compression, femur, hip, distal radioulnar, rib, hand and feet bones. Patients who had osteoporosis at the femur, osteoporosis or osteopenia in the lumbar spine or forearm in the initial BMD study were found to have an increased risk of fracture (P<0.05). Patients who were on TAM and AI sequentially had an increased risk of fracture (P<0.05) compared AI alone. The use of bisphosphonates and the duration of use were significantly associated with fracture (P<0.05) as these patients already had osteoporosis. The age, race, duration of AI use and the use of calcium and vitamin D were not found to be significantly different in patients who had fractures compared to those who did not. In the 24 patients who had two BMD studies, there was no significant change in the BMD overall. Conclusions: Patients with osteoporosis or osteopenia at baseline have an increased risk of fracture with the use of hormonal therapies for breast cancer and DCIS. This risk was not eliminated by the use of bisphosphonates. Sequential use of tamoxifen and aromatase inhibitors increase the risk of fractures. Bone mineral density studies done prior to the initiation of hormonal therapy for breast cancer maybe useful estimating the risk of fracture while on treatment.

Objectives. Homeless adults have an increased risk of infectious diseases due to sexual and drug-related behaviors and substandard living conditions. We investigated the prevalence and risk factors for presence of hepatitis A virus (HAV) antibodies among homeless and marginally housed adults. Methods. We analyzed serologic and questionnaire data from a study of marginally housed and homeless adults in San Francisco from April 1999 to March 2000. We tested seroprevalance for total antibodies to HAV (anti-HAV) and analyzed data using Chi-square tests and logistic regression. Results. Of the 1,138 adults in the study, 52% were anti-HAV positive. The anti-HAV prevalence in this study population was 58% higher than the expected prevalence based on age-specific prevalence rates from the general population. Number of years of homelessness (≤1, 2-4, and ≥5 years) was associated with anti-HAV prevalence (46%, 50%, and 61%, respectively, p<0.001). We found other differences in anti-HAV prevalence (p<0.05) for ever having injected drugs (63% vs. 42% for non-injectors), being foreign-born (75% vs. 51% among U.S.-born), race/ethnicity (72%, 53%, and 45% for Hispanic, white, and black people, respectively), and increasing age (38%, 49%, and 62% among those aged <35, 35-45, and >45 years, respectively). These variables all remained significant in a multivariate model. Conclusions. We found overall anti-HAV prevalence elevated in this San Francisco homeless population compared with the general U.S. population. These data show that anti-HAV was associated with homelessness independent of other known risk factors, such as being foreign-born, race/ethnicity, and injection drug use. This increase indicates an excess risk of HAV infection and the potential need to offer hepatitis A vaccination as part of homeless services.
