    Introduction: Appalachian residents are more likely than other populations to have Type 2 Diabetes Mellitus (T2DM) and to experience more severe complications from the disease, including excess and premature mortality. Methods: This study examines health alongside sociodemographic factors, psychosocial factors (including knowledge, empowerment, social support/function, religiosity, distress), and perceived problems in diabetes management that may influence self-care and HbA1c among vulnerable rural residents. A survey of a community–based sample of 356 adults with diagnosed diabetes or HbA1c \u3e 6.5 was conducted in six counties in Appalachian Kentucky. Results: Findings suggest that neither religiosity nor social support/function mediate/moderate the relationship between psychosocial factors and dependent variables (problem areas in diabetes, T2DM self-care or HbA1c). Results also suggest that distress is a predictor of problem areas in diabetes, and both distress and empowerment are predictors of T2DM self-care. Implications: This study addresses the gap in the literature concerning the influence of psychosocial factors on problem areas in diabetes, T2DM self-care and HbA1c among vulnerable rural residents, as well as the potential mediating/modifying effects of religiosity and social function/support. Future research is needed to inform strategies for identifying and addressing distress among vulnerable populations burdened by T2DM, including Appalachian adults

    Objective: Comparison of short-and long-term effects after laparoscopic Heller myotomy (LHM) and endoscopic balloon dilation (EBD) considering the need for retreatment. Background: Previously published studies have indicated that LHM is the most effective treatment for Achalasia. In contrast to that a recent randomized trial found EBD equivalent to LHM 2 years after initial treatment. Methods: A search in Medline, PubMed, and Cochrane Central Register of Controlled Trials was conducted for prospective studies on interventional achalasia therapy with predefined exclusion criteria. Data on success rates after the initial and repeated treatment were extracted. An adjusted network meta-analysis and meta-regression analysis was used, combined with a headto-head comparison, for follow-up at 12, 24, and 60 months. Results: Sixteen studies including results of 590 LHM and EBD patients were identified. Odds ratio (OR) was 2.20 at 12 months (95% confidence interval: 1.18-4.09; P = 0.01); 5.06 at 24 months (2.61-9.80; P < 0.00001) and 29.83 at 60 months (3.96-224.68; P = 0.001). LHM was also significantly superior for all time points when therapy included re-treatments , and 17.90 (2.17-147.98); P ≤ 0.01 for all comparisons) Complication rates were not significantly different. Meta-regression analysis showed that amount of dilations had a significant impact on treatment effects (P = 0.009). Every dilation (up to 3) improved treatment effect by 11.9% (2.8%-21.8%). Conclusions: In this network meta-analysis, LHM demonstrated superior short-and long-term efficacy and should be considered first-line treatment of esophageal achalasia.

The disease is likely caused by a virus-induced autoimmune response, but this is still debated. 1 The incidence in the Western world is 1/100 000. 2-4 Treatment can be pharmacological, endoscopic, or surgical. Pharmacological treatment is only marginally effective and is reserved for patients with mild symptoms or who refuse other treatments. 7-9 Several studies and a large meta-analysis have indicated that laparoscopic Heller myotomy (LHM) is the most effective treatment for achalasia. 3,4,10 However, a recent large prospective randomized controlled trial (RCT) comparing EBD and LHM has challenged this view. 11 This study found similar success rates for EBD and LHM 2 years after initial treatment. However, the number of EBD interventions per patient was notably higher than other studies. 3,11 The purpose of this meta-analysis is to determine which treatment is most effective at relieving symptoms and to further clarify the impact of retreatments for patients with achalasia. METHODS This meta-analysis was registered in the international register of systematic reviews (PROSPERO) (CRD42012002071). 12 Search Strategy and Trial Selection A prospective search of Medline, PubMed, and Cochrane Central Register of Controlled Trials was performed to identify relevant publications. The search keyword was "Esophageal Achalasia." Subsequently, the search was limited by the terms "Human," "Clinical Trial," and publication language "English." Publications from 1975 through October 2011 were considered for review To obtain indirect evidence by adjusted network meta-analysis, relative evidence is needed (LHM vs X; EBD vs X). Therefore, success rates were compared with those of either EBTI or open Heller myotomy (OHM). Direct evidence was achieved from head-to-hea

    The Mediating/Moderating Role of Cultural Context Factors on Self-Care Practices among Those Living with Diabetes in Rural Appalachia

    Background The aim of this study was to examine whether cultural factors, such as religiosity and social support, mediate/moderate the relationship between personal/psychosocial factors and T2DM self-care in a rural Appalachian community. Methods Regression models were utilized to assess for mediation and moderation. Multilevel linear mixed effects models and GEE-type logistic regression models were fit for continuous (social support, self-care) and binary (religiosity) outcomes, respectively. Results The results indicated that cultural context factors (religiosity and social support) can mediate/moderate the relationship between psychosocial factors and T2DM self-care. Specifically, after adjusting for demographic variables, the findings suggested that social support may moderate the effect of depressive symptoms and stress on self-care. Religiosity may moderate the effect of distress on self-care, and empowerment was a predictor of self-care but was not mediated/moderated by the assessed cultural context factors. When considering health status, religiosity was a moderately significant predictor of self-care and may mediate the relationship between perceived health status and T2DM self-care. Conclusions This study represents the first known research to examine cultural assets and diabetes self-care practices among a community-based sample of Appalachian adults. We echo calls to increase the evidence on social support and religiosity and other contextual factors among this highly affected population.

    The use of social services by community-dwelling older persons who are at risk of institutionalization: a survey

    Get PDF
    The use of community-based social services additionally to regular home help services to support older persons at risk of institutionalization was studied. Structured interviews were held with 292 persons, who specifically pointed out that they prefer to remain independently at home. Bivariate and multivariate logistic regression models were developed to study the association between social service use and personal, health-related and wellbeing characteristics. 195 respondents indicated that they made use of at least one social service (68%). Only three services (individual care, social-cultural activities and restaurant facilities), out of nine, were used regularly. Those who lived in a sheltered environment or were supported by informal caregivers or who visited day care had a significantly higher probability of using these services. More attention should be given to the nature and accessibility of community-based social services in order to have distinctive added value in enabling older persons to age in place

    Activity of lapatinib a novel HER2 and EGFR dual kinase inhibitor in human endometrial cancer cells

    In this study, we explore the therapeutic potential of lapatinib a selective inhibitor of both the EGFR and HER2 tyrosine kinases for the treatment of endometrial cancer. The effect of lapatinib on tumour cell growth and receptor activation was studied in a panel of human endometrial cancer cell lines. Candidate molecular markers predicting sensitivity were assessed by baseline gene expression profiling, ELISA, and western blot analyses. Multiple drug effect/combination index (CI) isobologram analysis was used to study the interactions between chemotherapeutic drugs and lapatinib. Concentration-dependent anti-proliferative effects of lapatinib were seen in all endometrial cancer cell lines tested, but varied significantly between individual cell lines (IC50 range: 0.052–10.9 μmol). HER2 overexpression or increased expression of EGFR was significantly associated with in vitro sensitivity (P=0.024 or 0.011, respectively). Lapatinib exerts growth inhibition in a PTEN-independent manner. Sensitive cell lines also exhibited increased expression of EGFR ligands or HER3. In contrast, lapatinib-resistant cell lines exhibited high androgen receptor (AR) levels or epithelial-to-mesenchymal transition (post-EMT) features. In endometrial cancer cells, at a wide range of clinically achievable drug concentrations, additive and synergistic interactions were observed for lapatinib plus carboplatin, paclitaxel, docetaxel, and doxorubicin. These observations provide a clear biologic rational to test lapatinib as a single agent or in combination with chemotherapy in endometrial cancer with HER2 overexpression. Expression of EGFR, its ligands, HER3, AR, and post-EMT markers warrant further evaluation to help define patients with HER2-nonoverexpressing endometrial cancer most likely to benefit from lapatinib

    Risk of breast cancer in young women in relation to body size and weight gain in adolescence and early adulthood

    Findings have been inconsistent on effects of adolescent body size and adult weight gain on risk of breast cancer in young women. These relations were examined in a population-based case control study of 1590 women less than 45 years of age newly diagnosed with breast cancer during 1990–1992 in three areas of the US and an age-matched control group of 1390 women. Height and weight were measured at interview and participants asked to recall information about earlier body size. Logistic regression was used to estimate the relative risk of breast cancer adjusted for other risk factors. Women who were either much heavier or lighter than average in adolescence or at age 20 were at reduced risk. Weight gain after age 20 resulted in reduced risk, but the effect was confined to early-stage and, more specifically, lower grade breast cancer. Neither the risk reduction nor the variation by breast cancer stage or grade was explained by the method of cancer detection or by prior mammography history. These findings suggest that relations between breast cancer risk in young women and body weight at different ages is complex and that the risk reduction with adult weight gain is confined to less aggressive cancers. © 1999 Cancer Research Campaig
