Prevalence of computer vision syndrome: A systematic review and meta-analysis

Purpose This review aimed to estimate the prevalence of computer vision syndrome (CVS) in the general population and subgroups. Methods A search was conducted in the following the databases: PubMed, SCOPUS, EMBASE, and Web of Science until February 13, 2023. We included studies that assessed the prevalence of CVS in any population. The Joanna Briggs Institute's critical appraisal tool was used to evaluate the methodological quality. A meta-analysis of the prevalence of CVS was done using a random-effects model, assessing the sources of heterogeneity using subgroup and meta-regression analyses. Results A total of 103 cross-sectional studies with 66 577 participants were included. The prevalence of CVS was 69.0% (95% CI: 62.3 to 75.3; I2: 99.7%), ranging from 12.1 to 97.3% across studies. Point prevalence was higher in women than in men (71.4 vs. 61.8%), university students (76.1%), Africa (71.2%), Asia (69.9%), contact lens wearers (73.1% vs. 63.8%) in studies conducted before the COVID-19 pandemic (72.8%), and in those that did not use the CVS-Q questionnaire (75.4%). In meta-regression, using the CVS-Q scale was associated with a lower prevalence of CVS. Conclusion Seven out of ten people suffer from CVS. Preventive strategies and interventions are needed to decrease the prevalence of this condition which can affect productivity and quality of life. Future studies should standardize a definition of CVS. (AU)

Self-reported perceptions and knowledge of telemedicine in medical students and professionals who enrolled in an online course in Peru.

BACKGROUND: Telemedicine has become more relevant during the COVID-19 pandemic. However, medical students and professionals do not acquire competences in telemedicine during their training. Our objective was to describe the self-reported perception and baseline knowledge of telemedicine among medical students and professionals enrolled in a virtual course. METHODS: Cross-sectional study that included physicians or medical students aged 18 years or older who were interested in a free virtual telemedicine course and who completed the data collection questionnaire. We used a Likert scale to assess the self-reported perceptions of four domains related to telemedicine. The participants were grouped into three levels for each domain: low, medium and high. We also objectively assessed telemedicine knowledge by means of 10 questions, with a cut-off point of 50% of correct answers. The Fisher's exact test, the Chi-square test, and the Mann-Whitney U test were used for the comparison of categorical data. A p-value < 0.05 was considered statistically significant. RESULTS: We included 161 participants: 118 medical students and 43 physicians. We observed no significant differences between medical students and physicians in self-reported perceptions of knowledge, security, or utility of telemedicine. However, students had a high self-reported perception of the disadvantages of telemedicine especially related to patient security (p = 0.018), efficiency of care (p = 0.040), and the possibility of medical malpractice (p = 0.010) compared to physicians. Nearly half of the students (n = 53,44.9%) and physicians (n = 22,51.7%) answered 50% or more of the questions related to telemedicine knowledge correctly. CONCLUSION: Among the physicians and medical students enrolled in the course, the students perceived the disadvantages of telemedicine more frequently. Although physicians and students have limited knowledge of telemedicine, there appears to be no influence of experience and prior training in telemedicine.

Adherence to Mediterranean diet associated with health-related quality of life in children and adolescents: a systematic review.

BACKGROUND: Health-related quality of life (HRQoL) has become a significant outcome in assessing interventions in the pediatric population and could be influenced by diet patterns. The Mediterranean diet (MD) pattern has been related to multiple positive health outcomes, including decreased cardiovascular risk and better mental health. We aimed to evaluate the association between MD adherence and HRQoL in children and adolescents. METHODS: The literature search was conducted in PubMed, Cochrane Library, Scopus, Web of Science, Embase, and Ovid-MEDLINE databases from inception to May 2022. Two researchers independently checked titles and abstracts, evaluated full-text studies, extracted data, and appraised the risk of bias using the Newcastle-Ottawa Scale (NOS). RESULTS: Eleven studies (1 longitudinal and 10 cross-sectional), totaling 6,796 subjects, were included. Ten studies assessed MD adherence with KIDMED index, and one assessed MD adherence with Krece Plus test, while all included studies assessed HRQoL with a KIDSCREEN test. All studies analyzed the association between MD adherence and HRQoL with linear regression, and eight used adjusted models. Five studies found a significant positive association of MD adherence with HRQoL, with ß-values ranging from 0.13 to 0.26. Two found a nonsignificant positive relationship, while one found a negative association. According to the NOS criteria, the risk of bias assessment showed four studies with a low risk of bias and seven with a high risk of bias. CONCLUSION: Our findings suggest a positive correlation of MD adherence with HRQoL in children and adolescents. However, future research is needed to strengthen the evidence of this relationship.

Self-perceived competencies on evidence-based medicine in medical students and physicians registered in a virtual course: a cross-sectional study.

BACKGROUND: Evidence-based medicine (EBM) is defined as the integration of the best available evidence from scientific studies with clinical experience (and context) and with patients' values and preferences. The objective of the present study was to describe self-perceived EBM competencies in physicians and medical students enrolled in a massive virtual EBM course. METHODS: Analytical cross-sectional study. People interested in a free virtual EBM course fulfilled their data in a virtual form for their registration in September 2020. In this form, 22 competencies related to four dimensions of EBM were evaluated: asking a clinical question, search, analysis, and application; using a 5-option Likert scale. The resulting database was analyzed, selecting people who claimed to be physicians or medical students of 18 years or more. RESULTS: 1793 participants were included: 1130 medical students and 663 physicians; more than 80% lived in Peru. The frequency of participants who agreed or strongly agreed with feeling qualified in each competence ranged: from 39.2% to 57.8% for the competencies of the 'Asking a clinical question' dimension, from 39.2% to 56.1% for 'Search,' from 19.9% to 32.0% for 'Analysis,' and from 19.6% to 29.9% for 'Application.' Both in physicians and students, the lowest frequencies were for the competencies of interpretation of impact measures, graphs, and results of systematic reviews; as well as shared decision making and calculation of expected benefit. Physicians who graduated more recently scored better on competencies from search and analysis dimensions. CONCLUSION: Among physicians and medical students enrolled in the course, self-perception of competencies was lower in the dimensions of analysis and application. More recently graduated physicians seem to have a greater self-perception of their research and analysis skills, probably due to curricular updates.List of abbreviations: EBM: Evidence-based medicine; CIMBE, for its acronym in Spanish: International Course on Evidence-Based Medicine; SOCIMEP, for its acronym in Spanish: Peruvian Medical Student Scientific Society.
