Project description:Finding ways to protect youth from maladjustment during adolescence and young adulthood is important, and youth of Mexican descent are key targets for such efforts given that they experience higher rates of depressive symptoms, risky behaviors, and sexual risk behaviors compared to youth from other ethnic/racial groups. Using a sample of younger (Mage Time 1 = 12.77 years) and older (Mage Time 1 = 15.70 years) siblings from an 8-year longitudinal study of 246 Mexican-origin families, we conducted path analyses to test whether older siblings' reports of sibling intimacy predicted younger siblings' later positive values and adjustment problems controlling for prior adjustment and maternal and paternal warmth. Additionally, we tested whether younger siblings' familism values moderated and their positive values mediated the sibling intimacy to adjustment problem linkages. Findings revealed that sibling intimacy in early adolescence predicted younger siblings' adjustment problems in young adulthood via their positive values in later adolescence, but only for younger siblings with strong familism values. This study highlights the importance of examining promotive factors, such as positive relationship qualities and familism values, and how positive values protect against problems in young adulthood. Results also have practical implications for prevention programs including the utility of promoting positive sibling relationships and values.

Project description:Background:Good sibling relationships in adulthood are known to be a protective factor for mental health. The quality of these relationships is influence by the sibship's inherent characteristics (e.g., birth order, number of brothers and sisters, sex composition, age gaps). The present study explored whether these same determinants can help to explain how individuals experience their relationship with a sibling who has been diagnosed with schizophrenia. Method:A total of 374 adults completed the Adult Sibling Relationship Questionnaire, a scale that probes the quality of these relationships on three dimensions: warmth, conflict, and rivalry. We also collected sociodemographic data and information about family structure from each of the participants. Participants were divided into two matched groups: nonclinical sibling group (n = 187) or schizophrenia sibling group (n = 187). Regression analyses were conducted to extract possible predictors of sibling relationship quality for each group. Further regression analyses then focused exclusively on relationships with an ill sibling, in order to study the role of disease-related variables in explaining each of the three dimensions. Results:Results showed that sociodemographic and family structure data explained a significant proportion of variance in the sibling relationship, but solely for nonclinical siblings. When participants had a sibling with schizophrenia, we found that disease-related variables (symptom severity, frequency of treatment) also had to be included to predict the conflict dimension. Conclusions:Our results suggest that feelings of conflict experienced by the schizophrenia sibling group were fueled by the symptoms the ill person displayed. Healthy brothers and sisters probably have only a poor understanding of these symptoms. This could be improved by supporting them and helping them learn more about the disease. Future research will have to prove that providing such support for siblings does indeed improve the quality of their sibling relationships and, by so doing, enhance the wellbeing of both members of a sibling dyad.

Project description:ObjectiveThere is ongoing debate regarding the association between epilepsy and obesity. Thus, the aim of this study was to examine the correlation between epilepsy and obesity.MethodThis study adhered to the PRISMA guidelines for systematic reviews and meta-analyses. On The Prospero website, this study has been successfully registered (CRD42023439530), searching electronic databases from the Cochr-ane Library, PubMed, Web of Sciences and Embase until February 10, 2024.The search keywords included "Epilepsy", "Obesity", "Case-Control Studies", "cohort studies", "Randomized Controlled Trial" and "Cross-Sectional Studies". The medical subject headings(MeSH) of PubMed was utilized to search for relevant subject words and free words, and a comprehensive search strategy was developed. Two reviewers conducted article screening, data extraction and bias risk assessment in strict accordance with the predefined criteria for including and excluding studies. The predefined inclusion criteria were as follows: 1) Inclusion of case-control, cohort, randomized controlled trial, and cross-sectional studies; 2) Segregation of subjects into epileptic patients and healthy controls; 3)Obesity as the outcome measure; 4) Availability of comprehensive data; 5) Publication in English. The exclusion criteria were as follows: 1) Exclusion of animal experiments, reviews, and other types of studies; 2) Absence of a healthy control group; 3) Incomplete data; 4) Unextractable or unconvertible data; 5) Low quality, indicated by an Agency for Healthcare Research and Quality(AHRQ) score of 5 or lower,or a Newcastle-Ottawa Scale (NOS) score less than 3. The subjects included in the study included adults and children, and the diagnostic criteria for obesity were used at different ages. In this study, obesity was defined as having a body mass index(BMI) of 25 kg/m2 or higher in adults and being above the 85th percentile of BMI for age in children. We used obesity as an outcome measure for meta-analysis using RevMan, version 5.3.ResultsA meta-analysis was conducted on a total of 17 clinical studies, which involved 5329 patients with epilepsy and 480837 healthy controls. These studies were selected from a pool of 1497 articles obtained from four electronic databases mentioned earlier. Duplicate studies were removed based on the search strategies employed. No significant heterogeneity was observed in the outcome measure of obesity in epileptic patients compared with healthy controls(p = 0.01,I2 = 49%). Therefore, a fixed effects model was utilized in this study. The findings revealed a significant difference in obesity prevalence between patients with epilepsy and healthy controls(OR = 1.28, 95%CI: 1.20-1.38, p<0.01).ConclusionThe results of this meta-analysis indicate that epilepsy patients are more prone to obesity than healthy people, so we need to pay attention to the problem of post-epilepsy obesity clinically. Currently, there is a scarcity of largescale prospective studies. Additional clinical investigations are warranted to delve deeper into whether obesity is a comorbidity of epilepsy and whether obesity can potentially trigger epilepsy.

Project description:IntroductionEngaging in teamwork requires a clear understanding of positive and negative behaviours that act as facilitators and barriers to collegial workplace relationships. Identifying and correcting underlying barriers, while promoting facilitators, is fundamental to improving care delivery and, ultimately, clinical outcomes. Despite a considerable amount of literature in this area, there is a lack of clarity of the different behaviours as several parallel literatures address similar questions about antecedents, processes and outcomes. The purpose of this study is to synthesise the current state of literature reporting on behaviours in workplace relationships. Using a scoping review methodology, the following research question will be addressed: "What is known about positive and negative behaviours in workplace relationships?"Methods and analysisWe will employ the methodological frameworks used by Arksey and O'Malley and Levac et al. The search strategy will include numerous electronic databases, grey literature sources and hand-searching of reference lists from 1990 to present with a limit to English language. Search strategies will be developed using controlled vocabulary and keyword terms related to various components of workplace relationships. Two reviewers will independently screen titles and abstracts for inclusion, followed by screening of the full text of potential articles to determine final inclusion. A descriptive numerical analysis will describe characteristics of included studies. A thematic analysis will provide an overview of the literature, including definitions, conceptual frameworks, antecedents, outcomes and interventions.DisseminationIn reviewing a wide range of positive and negative behaviours, then integrating into a manageable, meaningful whole, this study is a critical step in helping policymakers, leaders and healthcare professionals effectively use what is known thus far. Knowledge translation activities will occur throughout the study with dissemination of findings to local, national, and international stakeholders, including a wide range of clinicians, leaders and administrators in all sectors.

Project description:Tinnitus is the perception of sound in the absence of a corresponding external sound source, and bothersome tinnitus has been linked to poorer cognitive performance. This review comprehensively quantifies the association between tinnitus and different domains of cognitive performance. The review protocol was preregistered and published in a peer-reviewed journal. The review and analyses were reported according to Preferred Reporting Items for Systematic Review and Meta-analysis guidelines. Peer-reviewed literature was searched using electronic databases to find studies featuring participants with tinnitus who had undertaken measures of cognitive performance. Studies were assessed for quality and categorized according to an established cognitive framework. Random-effects meta-analyses were performed on various cognitive domains with potential moderator variables assessed where possible. Thirty-eight records were included in the analysis from a total of 1,863 participants. Analyses showed that tinnitus is associated with poorer executive function, processing speed, general short-term memory, and general learning and retrieval. Narrow cognitive domains of Inhibition and Shifting (within executive function) and learning and retrieval (within general learning and retrieval) were also associated with tinnitus.

Project description:The objective of the present study was to systematically review the existing literature for studies examining the association between posttraumatic stress disorder (PTSD) and stroke risk and perform a meta-analysis to obtain a pooled risk estimate describing the association. A literature search was conducted in PubMed, Embase, PSYCInfo, and CINAHL to identify relevant studies. Cohort and cross-sectional studies that reported PTSD exposure (i.e., PTSD diagnosis, probable PTSD, or the presence of PTSD symptoms) at baseline and the risk or odds of stroke associated with PTSD exposure during the study period were included in the analysis. A random-effects model was used to calculate the pooled hazard ratio (HR) for cohort studies estimating the association between PTSD and stroke. Overall, 11 studies met the inclusion criteria; eight were cohort studies, and three were cross-sectional studies. Two cohort studies and all cross-sectional studies used self-report of PTSD symptoms to measure the exposure. The pooled hazard ratio for the eight cohort studies showed that having PTSD was associated with a 59% higher risk of incident stroke, HR = 1.59, 95% CI [1.36, 1.86], I2 = 81%. The association remained statistically significant in a subgroup analysis of six United States-based studies, HR = 1.38; 95% CI [1.29, 1.49], I2 = 18%. The findings suggest that PTSD is associated with an increased risk of stroke. More studies are required to explore a causal association between PTSD and stroke.

Project description:BackgroundThis meta-analysis aimed to determine the prognostic impact of microscopically positive margins (R1) on primary gastrointestinal stromal tumors.MethodsA literature search was performed using PubMed, Embase, Web of Science, and Cochrane Library for studies up to 23 November 2020. The pooled disease-free survival (DFS) and overall survival (OS) between R1 and negative margins (R0) were estimated using a random-effects model.ResultsTwenty studies with 6,465 patients were included. Compared with R0 resection, R1 was associated with poor DFS in patients who did not receive adjuvant Imatinib (HR: 1.62, 95% CI: 1.26-2.09; P = 0.48, I2 = 0%; reference: R0). This negative impact of R1 disappeared with the use of adjuvant Imatinib (HR: 1.23, 95% CI: 0.95-1.60; P = 0.38, I2 = 6%; reference: R0). R1 was related to poor DFS in gastric GISTs (HR: 2.15, 95% CI: 1.15-5.02, I2 = 0%; reference: R0), which was attenuated in the subgroup of adjuvant Imatinib (HR: 2.24, 95% CI: 0.32-15.60; P = 0.84, I2 = 0%; reference: R0). Rectal GIST with R1 margin who even received adjuvant Imatinib still had poor DFS (HR: 3.79, 95% CI: 1.27-11.31; P = 0.54, I2 = 0%; reference: R0). Patients who underwent R1 resection had similar OS compared with those underwent R0 resection regardless of the use of adjuvant Imatinib.ConclusionR1 was associated with poor DFS for primary GISTs, which was attenuated by adjuvant therapy with Imatinib. Similar result was observed in the gastric GISTs subgroup. Rectal GIST patients with R1 resection had poor DFS even when they received adjuvant Imatinib. The R1 margin did not influence the OS of GISTs.

Project description:Children's inflammation may be an important link between parenting behaviors and health outcomes. The aims of this systematic review were to: (1) describe associations between parenting behaviors and child inflammatory markers, and (2) evaluate the relevance of existing literature to the review question. Database searches identified 19 studies that included a measure of positive or negative parenting behaviors and a marker of child inflammation, 53% of which measured parental responsiveness/warmth. Greater parental responsiveness/warmth was associated with lower levels of child pro-inflammatory markers in 60% of studies. Across studies, the association between parenting and child inflammation varied as a function of parenting construct, inflammatory measure, and sample characteristics. Studies were highly relevant, with 42% rated 5 + out of 6 for study's ability to address links between parenting behavior and child inflammation. If future research uncovers causal effects of parenting behaviors on inflammation, parenting interventions could be employed as a preventative tool.

Project description:IntroductionHeavy metals were classified as essential, probably essential, and potentially toxic in the general population. Until now, it has been reported inconsistently on the association between heavy metals and BC. In this meta-analysis, we aimed to assess the association between heavy metals and BC and review the potential mechanisms systematically.MethodsWe searched for epidemiological studies in English about the association between heavy metals and BC published before September 2020 in PubMed, Web of Science, and Embase databases. In total 36 studies, comprising 4,151 individuals from five continents around the world were identified and included.ResultsIn all biological specimens, Cu, Cd, and Pb concentrations were higher, but Zn and Mn concentrations were lower in patients with BC than in non-BC participants [SMD (95% CIs): 0.62 (0.12, 1.12); 1.64 (0.76, 2.52); 2.03 (0.11, 3.95); -1.40 (-1.96, -0.85); -2.26 (-3.39, -1.13); p = 0.01, 0.0003, 0.04, <0.0001, <0.0001]. Specifically, higher plasma or serum Cu and Cd, as well as lower Zn and Mn, were found in cases [SMD (95% CIs): 0.98 (0.36, 1.60); 2.55 (1.16, 3.94); -1.53 (-2.28, -0.78); -2.40 (-3.69, -1.10); p = 0.002, 0.0003, <0.0001, 0.0003]; in hair, only lower Zn was observed [SMD (95% CIs): -2.12 (-3.55, -0.68); p = 0.0004]. Furthermore, the status of trace elements probably needs to be re-explored, particularly in BC. More prospective studies, randomized clinical trials, and specific pathogenic studies are needed to prevent BC. The main mechanisms underlying above-mentioned findings are comprehensively reviewed.ConclusionFor BC, this review identified the current knowledge gaps which we currently have in understanding the impact of different heavy metals on BC.Systematic review registrationwww.crd.york.ac.uk/prospero/display_record.php?ID=CRD42020176934, identifier: CRD42020176934.

Project description:Depression and anxiety are well-known to be associated with adverse health outcomes in cardiac patients. However, there has been less work synthesizing the effects of positive psychological constructs (e.g., optimism) on health-related outcomes in cardiac patients. We completed a systematic review of prospective observational studies using established guidelines. A search of PubMed and PsycINFO databases from inception to January 2014 was used to identify articles. To be eligible, studies were required to assess effects of a positive psychological construct on subsequent health-related outcomes (including mortality, rehospitalizations, self-reported health status) in patients with established heart disease. Exploratory random effects' meta-analyses were performed on the subset of studies examining mortality or rehospitalizations. Seventy-seven analyses from 30 eligible studies (N=14,624) were identified. Among studies with 100 or more participants, 65.0% of all analyses and 64.7% of analyses adjusting for one or more covariates reported a significant (p<.05) association between positive psychological constructs and subsequent health outcomes. An exploratory meta-analysis of 11 studies showed that positive constructs were associated with reduced rates of rehospitalization or mortality in unadjusted (odds ratio=.87; 95% confidence interval [.83, .92]; p<.001) and adjusted analyses (odds ratio=.89; 95% confidence interval [.84, .91]; p<.001); there was little suggestion of publication bias. Among cardiac patients, positive psychological constructs appear to be prospectively associated with health outcomes in most but not all studies. Additional work is needed to identify which constructs are most important to cardiac health, and whether interventions can cultivate positive attributes and improve clinical outcomes.
