A BSTRACT Preconception health is defined as the physical and psychological well-being of women and men throughout their reproductive life. It is a method that raises healthy fertility and focuses on activities that persons can take to minimize risks, raise healthy lifestyles, and increase preparation for pregnancy. The purpose of this systematic review study was to assess men’s knowledge of preconception health. Electronic databases, including Web of Science, PubMed, Scopus, Sciencedirect, ProQuest, Cochrane, SAGE, Springer, Google Scholar, were searched for published studies from 2000 to March 2021 to identify the studies carried out on men’s knowledge of preconception health. The quality assessment was done using the critical appraisal skills program tool for qualitative studies and the Newcastle-Ottawa scale for cross-sectional studies. Of the 1195 references identified in the initial search, 11 studies met the inclusion criteria. Because of the diversity in the study design and the data collection tools used in studies, meta-analysis was impossible. All the studies of the present systematic review found that men’s preconception health knowledge is poor. This systematic review showed that men’s preconception health knowledge is low. Due to the limited studies of men’s knowledge about the importance of optimizing their health before pregnancy, further study of the issue is still required.
The focus of men’s health is within the context of preconception health and primary care, which involves a new method of engaging men’s attention to their preconception and general health. The aim of this review research is to offer health care practitioners a complete framework for men’s preconception care. From 2000 to October 2021, researchers examined electronic databases such as Web of Science, PubMed, Scopus, ScienceDirect, ProQuest, Cochrane, SAGE, Springer, UpToDate, and Google Scholar for published papers on men’s preconception care. Two independent authors assessed the quality of the included studies using techniques suitable for this type of investigation. Only 14 of the 835 studies that were found in the original search matched the inclusion criteria. Individual responsibility across the life span (evaluation of reproductive life plan, acquiring information about contraception) and risk assessment (age, medical and surgical history, medications, family history and genetic risks, social history, sexual health assessment, physical examination, laboratory testing, mental health, and intimate partner violence) are the two main topics of preconception care in men according to a review of studies. Our findings clearly demonstrated the critical components of a comprehensive preconception care approach for men. Therefore, preconception care for men remains a developing concept. Further research is required to develop standards for evaluating males during the preconception period.
Objective: Genital warts are a highly contagious sexually transmitted disease. It is caused by the human papillomavirus (HPV), which is transmitted through sexual contact. HPV is the most important cause of cervical cancer. This study aimed to evaluate the health belief model (HBM) constructs in adopting HPV preventive behavior in women referred to comprehensive health centers in Southwestern Iran. Materials and methods: This descriptive-analytical study was performed on 1000 women referring to health centers in Ahvaz during 2019-2020 who were selected via a two-stage stratified random sampling technique. Data were collected using a valid and reliable researcher-made questionnaire based on the HBM. The data were analyzed using descriptive statistics, t-test, ANOVA, Pearson correlation coefficient, and regression analysis in SPSS v.18, at a significance level lower than 0.05. Results: Total scale reliability of the tool was very good (α=0.828), as the Intra-cluster correlation coefficient (ICC) was to be 0.86. The mean of preventive behavior using an ANOVA test was significantly different at different levels of education (P <0.05). The mean and standard deviation of knowledge about HPV and preventive behavior was moderate (11.45±3.4). Pearson correlation coefficient showed a significant direct relationship between preventive behavior with awareness, perceived sensitivity, and self-efficacy and inversely related to perceived barriers. Perceived sensitivity (0.01) and self-efficacy (<0.001) were identified as the final predictors of behavior in regression analysis. Conclusion: As the results showed, designing programs to prevent HPV, considering the perceived role of perceived sensitivity and self-efficacy, increases the likelihood of effective interventions.
A reliable and practical determination of a chemical species’ solubility in water continues to be examined using empirical observations and exhaustive experimental studies alone. Predictions of chemical solubility in water using data-driven algorithms can allow us to create a rationally designed, efficient, and cost-effective tool for next-generation materials and chemical formulations. We present results from two machine learning (ML) modeling studies to adequately predict various species’ solubility using data for over 8,400 compounds. Molecular-descriptors, the most used method in previous studies, and Morgan fingerprint, a topological, circular-based hash of the molecules' structures, were applied to produce water solubility estimates. We trained all models on 80% of the total datasets using the Random Forest (RFs) technique as the regressor and tested the prediction performance using the remaining 20%, resulting in R2 test values of 0.88 and 0.82 for the descriptors and circular fingerprint methods, respectively. We interpreted the produced ML models and reported the most effective features for aqueous solubility measures using Shapley Additive exPlanations (SHAP) and thermodynamic analysis. Low error, ability to investigate the molecular-level interactions and compatible with thermodynamic quantities made fingerprint a distinct model compared to other available computational tools.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
