Mortality rates of coronavirus disease-2019 (COVID-19) continue to rise across the world. The impact of several risk factors on coronavirus mortality has been previously reported in several ...meta-analyses limited by small sample sizes. In this systematic review, we aimed to summarize available findings on the association between comorbidities, complications, smoking status, obesity, gender, age and D-dimer, and risk of mortality from COVID-19 using a large dataset from a number of studies. Electronic databases including Google Scholar, Cochrane Library, Web of Sciences (WOS), EMBASE, Medline/PubMed, COVID-19 Research Database, and Scopus, were systematically searched till 31 August 2020. We included all human studies regardless of language, publication date or region. Forty-two studies with a total of 423,117 patients met the inclusion criteria. To pool the estimate, a mixed-effect model was used. Moreover, publication bias and sensitivity analysis were evaluated. The findings of the included studies were consistent in stating the contribution of comorbidities, gender, age, smoking status, obesity, acute kidney injury, and D-dimer as a risk factor to increase the requirement for advanced medical care. The analysis results showed that the pooled prevalence of mortality among hospitalized patients with COVID-19 was 17.62% (95% CI 14.26-21.57%, 42 studies and 423,117 patients). Older age has shown increased risk of mortality due to coronavirus and the pooled odds ratio (pOR) and hazard ratio (pHR) were 2.61 (95% CI 1.75-3.47) and 1.31 (95% CI 1.11-1.51), respectively. A significant association were found between COVID-19 mortality and male (pOR = 1.45; 95% CI 1.41-1.51; pHR = 1.24; 95% CI 1.07-1.41), and current smoker (pOR = 1.42; 95% CI 1.01-1.83). Furthermore, risk of mortality among hospitalized COVID-19 patients is highly influenced by patients with Chronic Obstructive Pulmonary Disease (COPD), Cardiovascular Disease (CVD), diabetes, hypertension, obese, cancer, acute kidney injury and increase D-dimer. Chronic comorbidities, complications, and demographic variables including acute kidney injury, COPD, diabetes, hypertension, CVD, cancer, increased D-dimer, male gender, older age, current smoker, and obesity are clinical risk factors for a fatal outcome associated with coronavirus. The findings could be used for disease's future research, control and prevention.
Stress generation posits that (a) individuals at-risk for psychopathology may inadvertently experience higher rates of prospective dependent stress (i.e., stressors that are in part influenced by ...their thoughts and behaviors) but not independent stress (i.e., stressors occurring outside their influence), and (b) this elevated dependent stress, in some measure, is what places these individuals at-risk for future psychopathology. In recognition of 30 years of stress generation research, we conducted a systematic review and meta-analysis using frequentist and Bayesian approaches (102 articles with 104 eligible studies, N = 31,541). Generally strong support was found for psychopathology predicting dependent stress (e.g., ds Overall psychopathology = 0.36–0.52, BF₁₀ = 946.00 to 4.65 × 10¹⁸). Moderator analyses for dependent stress revealed larger effects for briefer assessments periods, shorter follow-ups, and self-report measures than for interviews. Among risk factors, depressogenic cognitive styles (ds = .26–.50, BF₁₀ = 47.50 to 1.00 × 10⁵) and general interpersonal vulnerability (ds = .26–.44, BF₁₀ = 2.72 to 2708.00) received the strongest support as stress generation mechanisms, and current evidence is modest for protective factors predicting dependent stress. Overall, larger effects were generally found for prospective prediction of dependent stress than independent stress. Evaluations of mediation in the research literature were relatively few, limiting the current review to qualitative analysis of the mediation component of stress generation. General support was found, however, for dependent stress as a mediator for psychopathology and associated risk factors in relation to subsequent psychopathology. The current review ends with recommendations for future research and integration of stress generation within minority stress frameworks.

The purpose of this study is to examine the relations among teacher value beliefs, personal characteristics, and Technological Pedagogical Content Knowledge (TPACK) in both intervention and ...non-intervention settings. One-hundred and nine in-service teachers from elementary to high schools participate in this study. Our findings reveal that compared to personal characteristics, teacher value beliefs are the only variable that can significantly predict TPACK across both settings. In addition, in the non-intervention setting, the relations between personal characteristics and TPACK are also moderated by teacher value beliefs. How to foster teacher value beliefs around technology integration is discussed.
•Examine the relations among value beliefs, personal characteristics, and TPACK.•The study was situated in intervention and non-intervention settings.•Value beliefs significantly predicted TPACK in both settings.•The moderation effects of value beliefs were found in non-intervention settings.•Value beliefs act as the pivotal factor for reframing teacher learning programs.
With increasingly prevalence of distributed renewable energy sources, Peer-to-Peer (P2P) energy trading has become an active research direction. This study explores the role of the participants’ ...Socio-Demographic Characteristics (SDCs) in the decision-making process P2P energy trading by proposing a personalized P2P energy trading system. The system periodically collects the participants’ bids and pair energy sellers and buyers to form transactions. An attention-based SDC inference system is developed, which identifies a participant’s SDCs from the on-site historical smart meter readings. Followed by this, the system analyzes the importance of energy buyers’ demands based on their SDCs, and an alternative current network constrained P2P energy market clearing model is formulated to maximize the participant population’s social warfare by considering their energy demand importance and economic benefits. Simulations based on real-world datasets are conducted to validate the proposed system.
•To propose a new Socio-Demographic Characteristic Inference (SDCI) system, which enables the market operator to understand the participants’ social-demographic characteristics from the power consumption data collected by smart meters deployed in the participants’ sites.•To propose a new P2P energy trading system, which periodically performs market clearing to form energy trading transactions by considering the participants’ socio-demographic characteristics.•A market clearing model is established for maximizing the social welfare of the participants while satisfying the Alternative Current (AC) constraints of the underlying power distribution network.
Productivity refers to the maximum use of human resources in service provision. Due to the existence of advanced equipment and instruments for surgery, the operating room is one of the most complex ...and income-generating sections of a hospital. Since the improvement of operating room nurses’ productivity can lead to enhanced hospital productivity, this study was done to determine the productivity rate of operating room nurses in Iran.
This cross-sectional study was done on 533 operating room nurses from 8 metropolises in Iran in 2022. The sampling method in this research was multistage. The data collection instruments were Hersy & Belanchard & Gold.Smith productivity questionnaire and demographic characteristics. After receiving the ethics code, data collection was done for three months. Descriptive and inferential analyses, including independent t-tests and analysis of variance, were used for data analysis. The collected data were analyzed by SPSS 18. P-value < 0.05 was considered statistically significant.
The mean age of the participants was 29.83 ± 5.94 and 421 of the participants were women. The mean and SD for total productivity in operating room nurses was obtained at 60.83 ± 12.78, below average. Data analysis shows that total productivity was significantly associated with marital status (P-value = 0.035) and working experience (P-value = 0.019).
Considering the low mean productivity rate of operating room nurses, researchers recommend that hospital managers pay more attention to the productivity of operating room nurses by knowing the influential factors and implementing proper and high-quality management.
Introduction and purpose: Immigrants are more susceptible to somatic symptom disorder because they often experience a series of traumatic and stressful events in their pre- and post-immigration ...lives. The present study was conducted to investigate the relationship between demographic characteristics and the severity of somatic symptoms in Iranian immigrants living in Germany. Methods: This correlational and cross-sectional descriptive study was conducted to explore the association between demographic characteristics and the severity of somatic symptoms of Iranian immigrants living in Germany in the summer of 2023. A total of 253 Iranian immigrants in Germany participated in this research, providing their responses via an online questionnaire. The questionnaire consisted of two parts of demographic information (including age, gender, marital status, education, occupation, proficiency in English and German, immigration ways, and length of stay) and a 15-item somatic symptoms questionnaire of the Patient Health Questionnaire by Spitzer et al. (1999). The collected data were subsequently analyzed in SPSS software (version 26) using descriptive statistics and stepwise regression. Results: The participants included 155 women and 98 men, with an average age of 35.15 and a standard deviation of 6.95. The average somatic symptoms in the groups of women (8.97), divorced people (10.9), diploma education and less (9.33), unemployed people (9.39), English language proficiency at the basic level (9.75) and German (9.96), migration through asylum (9.91), and six months stay (8.89) were higher than other groups. The regression model in five steps identified the variables of German language proficiency, gender, English language proficiency, migration ways, and marital status to predict the severity of somatic symptoms. The multiple correlation coefficient was 0.63, and the coefficient of determination (R2) was 0.40, which indicates that demographic characteristics can explain 40% of the changes in somatic symptoms of immigrants. Conclusion: It is essential to pay attention to the demographic characteristics of individuals in researching and treatment of somatic symptoms. Considering the individual-social background and the current situation of the immigrant will be the basis for better guidance in healthcare services.
Maternal ambivalence refers to the simultaneous experience of both negative and positive feelings about motherhood and the child. It has been suggested that maternal ambivalence exists on a continuum ...from manageable (healthy) to unmanageable (problematic) and can have wide-ranging psychological consequences. However, there are currently no empirically validated measures for examining manageable or unmanageable maternal ambivalence. In this article, we outline the development and initial validation of the Maternal Ambivalence Questionnaire (MAQ). An online study was conducted to evaluate the factor structure, construct validity, reliability, and relationships of the MAQ with demographic characteristics. The participants included a community sample of 502 mothers living in the United Kingdom with at least one child aged 0-11 years. Statistical analyses demonstrated a good fit for the 20-item measure and suggested five theoretically consistent factors. These factors are assessment of one's perception of self as a mother, awareness of conflicting feelings about motherhood, suppression of negative feelings about motherhood, internalization of negative feelings about motherhood, and externalization of negative feelings about motherhood. These factors were related in theoretically expected ways to parental reflective functioning capacity, parenting stress and guilt, and symptoms of depression. The study's findings indicate that the MAQ is a robust and reliable measure that contributes to a theoretical understanding and practical assessment of maternal ambivalence, facilitating insight into emotional challenges of motherhood.
