RESUMO
Sedentary behavior (SB) is associated with numerous negative health outcomes, independent of physical activity behavior. Older adults are the most sedentary population in the United States. Understanding the effects and characteristics of existing interventions to reduce SB can inform practice, future research, and public health initiatives to improve older adults' health. We conducted a systematic review and meta-analysis to examine existing SB intervention research among older adults and quantitatively synthesize intervention effects. Comprehensive searches were conducted to identify studies testing interventions to reduce SB time among adults at least 60 years old. Data on study design, intervention content and delivery, and participant characteristics were extracted from eligible studies. Standardized mean difference effect sizes (Cohen's d) were synthesized using a random-effects model for two-group pretest-posttest design studies. Twenty-two reports describing 17 distinct studies were included in the narrative synthesis, with eight studies included in the meta-analysis (k = 8; n = 1,024). Most interventions were theory-driven and employed multiple strategies, including education, self-monitoring, and goal setting. Although SB interventions significantly reduced total sedentary time, the overall effect was small (d = -0.25, 95% confidence interval [-0.50, 0.00], p = .05). Studies were significantly heterogeneous (Q = 22.34, p < .01); however, the small number of comparisons prevented moderator analyses. Practitioners should employ diverse SB-specific strategies to encourage older adults to reduce time spent sedentary. To develop public health programs targeting SB in older adults, future research should include measures of time spent in specific SB and duration/number of breaks in sedentary time and investigate SB intervention effects on health outcomes.

AIM: To synthesize and compare outcomes from controlled trials of interventions to improve heart failure self-care among adults. BACKGROUND: Heart failure self-care interventions are recommended for preventing and detecting exacerbations, improving symptom management and preventing hospitalizations. Little is known about the overall effectiveness of heart failure self-care programmes and which types of interventions show the greatest improvement in outcomes. DESIGN: Systematic review and meta-analysis, including moderator analyses. METHODS: Multiple databases (including MEDLINE/PubMed, CINAHL, PsycINFO, Scopus and Cochrane Central Register of Controlled Trials) will be searched from inception through 2018 along with grey literature searches to identify trials testing interventions to improve self-care outcomes of adults with heart failure. Data will be extracted from eligible studies on sample, methodological and intervention characteristics and data to calculate effect sizes. Data will be analysed using random-effects models. Moderator variables will be analysed with meta-regression and sub-group analyses. Risk for bias will be assessed using the Cochrane Risk for Bias tool and by examining potential sources of bias as moderator variables. Funding for this project began in July 2017. DISCUSSION: We will analyse self-care behaviour outcomes and clinical outcomes including hospitalizations, mortality, disease severity and quality of life. This will be the most extensive meta-analysis of heart failure self-care interventions to date. IMPACT: Comparative effectiveness of existing self-care interventions is not yet known. This research will identify the most promising self-care intervention components for designing better interventions and guide targeting of interventions to specific sub-populations. PROSPERO Registration Number: CRD42017075831.

The Learning and Action in Community Health project was implemented to gather preliminary data needed to inform community-engaged educational approaches to increase clinical research participation among racial minorities. The Health Belief Model was the theoretical framework utilized to develop the intervention and assessment tools. An educational session about clinical research and biorepository participation was designed using clinicaltrials.gov information and administered to adult, African American community residents (n = 60) in Atlanta, Georgia. Pre- and post-tests were collected and analyzed to assess changes in participants' knowledge, perceptions, and willingness to participate in clinical studies and biorepositories. There were statistically significant changes in knowledge about joining a clinical study (p < 0.001) and registry or biorepository (p < 0.001). There was no statistically significant change in willingness to participate in clinical research or biorepositories after the educational session. Focus groups were conducted to gather feedback on the educational session and perceived barriers and benefits to participating in clinical research. Perceived benefits were improving health, receiving incentives, early detection of health issues, and access to care. Perceived barriers included fear, lack of knowledge, historical mistrust of research, and time constraints. Results have implications for subsequent community-engaged approaches to increasing minority participation in clinical research.

A 17-years old girl presented with an 8-year history of absences with peri-oral twitching, eyelid twitching and head nodding, with poor response to anti-epileptic drugs. Video EEG revealed ictal and inter-ictal generalized spike wave discharges, and absences with peri-oral (predominant), eyelid, neck and shoulder myoclonia. There was also prominent eye closure sensitivity. Conundrums regarding epilepsy syndrome classification and pathophysiology are discussed.

Purpose: Inhibition of mTOR in addition to EGFR may overcome resistance to EGFR inhibitors in metastatic colorectal cancer (mCRC). This phase Ib/II study evaluated the safety and efficacy of the combination of irinotecan, panitumumab, and everolimus.Patients and Methods: Patients with KRAS exon 2 wild-type (WT) mCRC following failure of fluoropyrimidine-based therapy received i.v. irinotecan and panitumumab every 2 weeks, and everolimus orally throughout a 14-day cycle. The primary endpoint of the phase II study was response rate (RR). Secondary survival outcomes were calculated using the Kaplan-Meier method, and results were analyzed as intention to treat. A preplanned exploratory biomarker analysis was performed.Results: Forty-nine patients were enrolled. Dose level 1 (irinotecan 200 mg/m2, panitumumab 6 mg/kg, and everolimus 5 mg alternate day) was declared the MTD with no dose-limiting toxicities in six patients. Forty patients were treated at dose level 1: median age, 60 years (37-76); 65% male; 45% and 52.5%, respectively, with Eastern Cooperative Oncology Group values of 0/1. Median dose intensity was 85%. Grade 3 toxicities were diarrhea (23%), mucositis (18%), rash (13%), fatigue (8%), dehydration (5%), neutropenia (20%), febrile neutropenia (8%), hypomagnesemia (20%), and hypokalemia (8%). Grade 4 toxicities were hypomagnesemia (5%) and neutropenia (3%). RR was 48%, and stable disease was 43%. Median progression-free survival (PFS) was 5.6 months, and median overall survival (OS) was 10.8 months. Twenty-five patients were RAS/RAF WT and had an RR of 60%, median PFS of 6.4 months, and OS of 11.8 months.Conclusions: The toxicity of the panitumumab, irinotecan, and everolimus regimen is as expected and manageable. The RR of 60% in all RAS/RAF WT supports further study of this combination. Clin Cancer Res; 24(16); 3838-44. ©2018 AACR.

BACKGROUND: Poor adherence to medications is a common problem among heart failure (HF) patients. Inadequate adherence leads to increased HF exacerbations, reduced physical function, and higher risk for hospital admission and death. Many interventions have been tested to improve adherence to HF medications, but the overall impact of such interventions on readmissions and mortality is unknown. METHODS AND RESULTS: We conducted a comprehensive search and systematic review of intervention studies testing interventions to improve adherence to HF medications. Mortality and readmission outcome effect sizes (ESs) were calculated from the reported data. ESs were combined using random-effects model meta-analysis methods, because differences in true between-study effects were expected from variation in study populations and interventions. ES differences attributed to study design, sample, and intervention characteristics were assessed using moderator analyses when sufficient data were available. We assessed publication bias using funnel plots. Comprehensive searches yielded 6665 individual citations, which ultimately yielded 57 eligible studies. Overall, medication adherence interventions were found to significantly reduce mortality risk among HF patients (relative risk, 0.89; 95% CI, 0.81, 0.99), and decrease the odds for hospital readmission (odds ratio, 0.79; 95% CI, 0.71, 0.89). Heterogeneity was low. Moderator analyses did not detect differences in ES from common sources of potential study bias. CONCLUSIONS: Interventions to improve medication adherence among HF patients have significant effects on reducing readmissions and decreasing mortality. Medication adherence should be addressed in regular follow-up visits with HF patients, and interventions to improve adherence should be a key part of HF self-care programs.

OBJECTIVE: Using meta-analytic procedures to synthesize changes in patient-centered outcomes after medication adherence interventions. METHODS: Strategies to locate studies included online searches of 13 databases and 19 research registries, hand searches of 57 journals, and author and ancestry searches of all eligible studies. Search terms included patient compliance, medication adherence, and related terms. Searches were conducted for all studies published since 1960. Eligible published or unpublished primary studies tested medication adherence interventions and reported medication knowledge, quality of life, physical function, and symptom outcomes. Primary study attributes and outcome data were reliably coded. Overall standardized mean differences (SMDs) were analyzed using random-effects models. Dichotomous and continuous moderator analyses and funnel plots were used to explore risks of bias. RESULTS: Thorough searching located 141 eligible reports. The reports included 176 eligible comparisons between treatment and control subjects across 23,318 subjects. Synthesis across all comparisons yielded statistically significant SMDs for medication knowledge (d = 0.449), quality of life (d = 0.127), physical function (d = 0.142), and symptoms (d = 0.182). The overall SMDs for studies focusing on subsamples of patients with specific illnesses were more modest but also statistically significant. Of specific symptoms analyzed (depression, anxiety, pain, energy/vitality, cardiovascular, and respiratory), only anxiety failed to show a significant improvement after medication adherence interventions. Most SMDs were significantly heterogeneous, and risk of bias analyses suggested links between study quality and SMDs. CONCLUSIONS: Modest but significant improvements in patient-centered outcomes were observed after medication adherence interventions.

This systematic review applied meta-analytic procedures to synthesize medication adherence interventions that focus on adults with hypertension. Comprehensive searching located trials with medication adherence behavior outcomes. Study sample, design, intervention characteristics, and outcomes were coded. Random-effects models were used in calculating standardized mean difference effect sizes. Moderator analyses were conducted using meta-analytic analogues of ANOVA and regression to explore associations between effect sizes and sample, design, and intervention characteristics. Effect sizes were calculated for 112 eligible treatment-vs.-control group outcome comparisons of 34,272 subjects. The overall standardized mean difference effect size between treatment and control subjects was 0.300. Exploratory moderator analyses revealed interventions were most effective among female, older, and moderate- or high-income participants. The most promising intervention components were those linking adherence behavior with habits, giving adherence feedback to patients, self-monitoring of blood pressure, using pill boxes and other special packaging, and motivational interviewing. The most effective interventions employed multiple components and were delivered over many days. Future research should strive for minimizing risks of bias common in this literature, especially avoiding self-report adherence measures.

BACKGROUND: HLA-DRB1*15 genotype, previous infection with Epstein-Barr virus, and vitamin D insufficiency are susceptibility factors for multiple sclerosis, but whether they act synergistically to increase risk is unknown. We aimed to assess the contributions of these risk factors and the effect of established precursors of multiple sclerosis, such as brain lesions on MRI and oligoclonal bands in CSF at the time of incident demyelination, on development of multiple sclerosis in children. METHODS: In our prospective national cohort study, we assessed children who presented with incident CNS demyelination to any of the 16 paediatric health-care facilities or seven regional health-care facilities in Canada. We did univariate and multivariable analyses to assess contributions of HLA-DRB1*15, Epstein-Barr virus, vitamin D status, MRI evidence of brain lesions, and CSF oligoclonal bands as determinants of multiple sclerosis. We used classification and regression tree analyses to generate a risk stratification algorithm for clinical use. FINDINGS: Between Sept 1, 2004, and June 30, 2010, we screened 332 children of whom 302 (91%) were eligible and followed-up for a median of 3·14 years (IQR 1·61-4·51). 63 (21%) children were diagnosed with multiple sclerosis after a median of 127 days (99-222). Although the risk of multiple sclerosis was increased with presence of one or more HLA-DRB1*15 alleles (hazard ratio [HR] 2·32, 95% CI 1·25-4·30), reduced serum 25-hydroxyvitamin D concentration (HR per 10 nmol/L decrease 1·11, 1·00-1·25), and previous Epstein-Barr-virus infection (HR 2·04, 0·99-4·20), no interactions between these variables were detected on multivariate analysis. Multiple sclerosis was strongly associated with baseline MRI evidence of one or more brain lesion (HR 37·9, 5·26-273·85) or CSF oligoclonal bands (6·33, 3·35-11·96), suggesting established disease. One patient diagnosed with multiple sclerosis had a normal MRI scan, and therefore sensitivity of an abnormal MRI scan for multiple sclerosis diagnosis was 98·4%. INTERPRETATION: Risk of multiple sclerosis in children can be stratified by presence of HLA-DRB1*15 alleles, remote Epstein-Barr virus infection, and low serum 25-hydroxyvitamin D concentrations. Similar to previous studies in adults, brain lesions detected on MRI and CSF oligoclonal bands in children are probable precursors to the clinical onset of multiple sclerosis. Children with a normal MRI are very likely to have a monophasic illness. FUNDING: Canadian Multiple Sclerosis Scientific Research Foundation.

In 1980, Froedtert Hospital opened its doors using an innovative registered nurse scheduling model. The hospital has grown to 500 beds, with over 1,600 registered nurses, and continues to use the 7/70 staffing pattern as a core scheduling model. Registered nurses work a straight seven, 10-hour days, and then have 1 week off, or 26 weeks off a year. For professional registered nurses in acute care, the schedule is predictable and consistent for years. This scheduling pattern has resulted in excellent registered nurse satisfaction, increased retention, and consistency in care delivery teams since 1980.

CONTEXT: Most adults do not achieve adequate physical activity levels. Despite the potential benefits of worksite health promotion, no previous comprehensive meta-analysis has summarized health and physical activity behavior outcomes from such programs. This comprehensive meta-analysis integrated the extant wide range of worksite physical activity intervention research. EVIDENCE ACQUISITION: Extensive searching located published and unpublished intervention studies reported from 1969 through 2007. Results were coded from primary studies. Random-effects meta-analytic procedures, including moderator analyses, were completed in 2008. EVIDENCE SYNTHESIS: Effects on most variables were substantially heterogeneous because diverse studies were included. Standardized mean difference (d) effect sizes were synthesized across approximately 38,231 subjects. Significantly positive effects were observed for physical activity behavior (0.21); fitness (0.57); lipids (0.13); anthropometric measures (0.08); work attendance (0.19); and job stress (0.33). The significant effect size for diabetes risk (0.98) is less robust given small sample sizes. The mean effect size for fitness corresponds to a difference between treatment minus control subjects' means on VO2max of 3.5 mL/kg/min; for lipids, -0.2 on the ratio of total cholesterol to high-density lipoprotein; and for diabetes risk, -12.6 mg/dL on fasting glucose. CONCLUSIONS: These findings document that some workplace physical activity interventions can improve both health and important worksite outcomes. Effects were variable for most outcomes, reflecting the diversity of primary studies. Future primary research should compare interventions to confirm causal relationships and further explore heterogeneity.

PURPOSE: This study investigated the effectiveness of interventions to improve medication adherence (MA) in older adults. DESIGN AND METHODS: Meta-analysis was used to synthesize results of 33 published and unpublished randomized controlled trials. Random-effects models were used to estimate overall mean effect sizes (ESs) for MA, knowledge, health outcomes, and health services utilization. RESULTS: Data were synthesized across 11,827 participants. Interventions significantly improved MA (ES = 0.33), knowledge (ES = 0.48), and diastolic blood pressure (ES = 0.19). Nonsignificant effects were found for systolic blood pressure (ES = 0.21), other health outcomes (ES = 0.04), and health services utilization (ES = 0.16). Moderator analyses showed larger adherence ESs for interventions employing special medication packaging, dose modification, participant monitoring of medication effects and side effects, succinct written instructions, and standardized (not tailored) interventions. Larger effects were found when a moderate proportion of participants were women, for participants taking 3-5 medications, and when pill count adherence was measured. IMPLICATIONS: The findings document that interventions increase MA in older adults. The considerable heterogeneity in the magnitude of effects across studies and results of the moderator analyses demonstrate the need for additional empirical research to optimize interventions.

PURPOSE: Precisely described interventions in nursing research reports are essential as a foundation for nursing practice and to facilitate future research. The purpose of this project was to characterize the intervention descriptions in nursing intervention research reports. DESIGN AND METHODS: Quantitative content analysis was used to analyze intervention descriptions in reports published in English-language general nursing journals during 2005. Normative analysis was used to examine reports for details related to intervention content and delivery. Physical unit analysis was used to compare relative amounts of article space devoted to intervention description vs. other methodological details. FINDINGS: Results were tabulated for 141 research articles published in 27 journals. Analysis indicated incomplete reporting of intervention details in many articles. Dose and dosing frequency were rarely completely defined. Delivery setting and interventionist were frequently not indicated, and the professional credentials of nurse interventionists were often unclear. While descriptions of interventions involving substances or devices were typically detailed, the specifics of psychological, educational, behavioral, and systems-level interventions were often lacking. Intervention descriptions averaged 7.27% of total article space, whereas nonintervention methodological descriptions averaged 20.74% of space. Of studies examined, only 38 (27.0%) reported enough detail to potentially replicate the study or translate the intervention into practice. CONCLUSIONS: Intervention descriptions in general nursing journals lack sufficient detail to provide the evidence basis for practice.

In early 1996, the Ben Gurion University Faculty of Health Sciences (BGU), Beer-Sheva, Israel, in collaboration with Columbia University Medical Center (CUMC), New York City, United States, decided to found a second medical school within BGU, the Medical School for International Health (MSIH), to prepare students to work both in medicine and in cross-cultural and international health and medicine (IHM). Methods used to establish and jointly run MSIH include (1) defining clearly the tasks of each university according to how it can best contribute to the new school; (2) establishing an organizational structure in each university for accomplishing these tasks; (3) establishing clear communication between the two organizational structures; (4) defining outcomes to measure success; and (5) developing methods for addressing management problems. CUMC's functions were admission, public relations, and the fourth-year elective program. BGU's functions were developing and running an innovative curriculum, including a four-year required track in IHM, evaluating students, taking the lead in helping students' with their personal problems, and managing financial aid. The first students were admitted in 1998. Variables reflecting MSIH's success include scores on the United States Medical Licensing Examination, residency placement, the attrition rate, and success in preparing students in IHM (e.g., success in learning cross-cultural medicine and the percentage of students who work in IHM). MSIH is running well and has solved its inter-university management problems. Its 85 graduates matched at very good to excellent U.S. hospitals and have learned and maintained enthusiasm for the IHM curriculum.
