The effect of micro-learning on trauma care knowledge and learning satisfaction in nursing students.

BACKGROUND: Despite the fact that there are few formal trauma training courses for nurses, they play an important role in the care of trauma patients. This study aims to investigate the effect of micro-learning on the knowledge of managing trauma patients and learning satisfaction in nursing students. METHODS: The convenience sampling method was used to enroll 30 final-year nursing students from Alborz University of Medical Sciences in this quasi experimental One-group pretest -posttest design. The educational content was created and repeated 4 times over the course of 36 days using a micro-learning approach through whiteboard animations, video casts, and live videos. MCQ scenario-based exam was used to assess participants' knowledge of trauma in three phases: pretest, immediately following the intervention, and one month after the end of the educational program. An e-learning satisfaction psychometric questionnaire was used to measure satisfaction. RESULTS: The mean knowledge score 1 month after the intervention did not differ significantly from the score immediately after the intervention (p = 1), but there was a significant relationship between the mean knowledge score immediately after the intervention and before that (p = 0.047). Demographic variables and knowledge of trauma management did not differ statistically significant. The majority of students were pleased with how the course was implemented (5.64). CONCLUSION: The use of micro-learning has a positive effect on the promotion and retention of knowledge of trauma care, as well as increasing nursing students' satisfaction. Micro-learning is proposed as a new educational approach that can be used as a complementary or as a stand-alone method to convey important educational concepts and increase learner satisfaction.

Association of dietary phytochemical index with cardiometabolic risk factors.

Objective(s): Cardio-metabolic risk factors are becoming a global health concern. To address this problem, one of the proposed ways is to focus on phytochemical-rich foods consumption. Therefore, we aimed to summarize the results of observational studies (cohorts, case-control, and cross-sectional) that investigated the association between dietary phytochemical index (PI) as a new index for evaluating phytochemical-rich food intake and various risk factors of cardio-metabolic disorders. Methods: We conducted a comprehensive systematic review through PubMed, Scopus, and Web of Science databases. The literature search was performed up to August 2021 with no publication year restriction on observational studies investigating the association between PI and cardiometabolic risk factors on adults and children. A random-effect meta-analysis was used. Results: Overall, 16 articles (cross-sectional, case-control, cohort) were eligible for this systematic review and 8 studies with 99771 participants were included in the meta-analysis. Random effect meta-analysis showed that adherence to higher dietary PI decrease the odds of abdominal obesity (OR: 0.73, 95% CI: 0.58, 0.88, I2: 84.90), generalized obesity (OR: 0.84, 95% CI: 0.69, 0.98, I2: 68.10), hypertriglyceridemia (OR: 0.81, 95% CI: 0.73, 0.89, I2: 0.00), hypertension (OR: 0.86, 95% CI: 0.73, 0.99, I2: 7.02), and MetS (OR: 0.79, 95% CI: 0.69, 0.88, I2: 84.90). However, results considering the associations between dietary PI with glycemic indices, and low high-density lipoprotein cholesterol (HDL-C) were not significant (p<0.05). Conclusion: Evidence showed adverse associations between dietary PI and some cardio-metabolic risk factors such as obesity, hypertriglyceridemia, hypertension and metabolic syndrome.

Post-traumatic stress disorder and mental health assessment of seafarers working on ocean-going vessels during the COVID-19 pandemic.

BACKGROUND: There are increasing concerns about mental health consequences of the COVID-19 pandemic among seafarers. This study aims to assess the effects of the current global health pandemic on life satisfaction and adverse psychological outcomes among seafarers. METHODS: In this cross-sectional study, 470 multinational seafarers working on board ships of two international shipping companies were assessed. Mental health outcomes were assessed by the general anxiety disorder (GAD-7) questionnaire, post-traumatic stress disorder (PTSD-8) questionnaire, and patient health questionnaire (PHQ-9) depressive severity score. Multivariate logistic regression was used to determine the association of demographic and work-related variables with mental health outcomes. RESULTS: Overall, 439 out of 470 invited seafarers with a mean age of 34.5 (SD: 8.05) years participated in this study (participation rate: 93.4%). The prevalence of anxiety, depressive, and post-traumatic stress symptoms was 12.4, 14.1, and 37.3%, respectively. In the multivariate model, the current vessel's signing duration was directly associated with the odds of depressive and intrusion symptoms. Moreover, the duration of work per week was inversely associated with hyper-vigilance and avoidance. Also, non-officers, compared to officers, experienced significantly lower anxiety and depressive symptoms, hyper-vigilance, and avoidance. CONCLUSION: The present study revealed a high prevalence of mental health problems among seafarers during the COVID-19 pandemic. We recommend that more evidence is generated regarding psychosocial health issues for this vulnerable occupation.

Dietary diversity score and cardio-metabolic risk factors: an updated systematic review and meta-analysis.

CONTEXT: Dietary diversity score (DDS) has been known as a useful and convenient indicator of overall diet quality. Previous studies have reported the association between DDS and health problems such as diabetes, metabolic syndrome and cardiovascular disease. OBJECTIVES: This systematic review and meta-analysis aimed to assess the association between dietary diversity score (DDS) and cardio-metabolic risk factors such as obesity and overweight, lipid profile, blood pressure, metabolic syndrome (MetS) and diabetes. DATA SOURCES: We systematically searched PubMed and NLM Gateway, Scopus and Institute of Scientific Information (ISI) by up to October 2019. DATA EXTRACTION: All observational studies which assessed the association of DDS with cardio-metabolic risk factors including anthropometric measures, blood pressure, lipid profile, glycemic indices and MetS without limitation in time of publication and language were included and critically reviewed by two independent experts. Random-effects meta-analysis was used to estimate the effect sizes. DATA ANALYSIS: Among 843 documents retrieved from literature search, 23 studies met the inclusion criteria for systematic review, and 18 studies were eligible for meta-analysis. Random-effects meta-analysis showed that the association of DDS with obesity, abdominal obesity, overweight, body mass index, MetS, diabetes, blood pressure, and lipid profile (TC, LDL, HDL) was not statistically significant. On the other hand, the association of DDS and TG was statistically significant (SMD: - 0.23, 95% CI - 0.45, - 0.01). CONCLUSIONS: Our findings revealed that there was no significant association between DDS and cardio-metabolic risk factors. Reassessment of the overall DDS tool as a criterion of diet quality and production of new and valid DDS standard tools is highly desirable. More high-quality studies are also needed to confirm the findings of this study. STUDY REGISTRATION: This study is registered as PROSPERO CRD42020157127. LEVEL OF EVIDENCE: Level I, systematic reviews and meta-analyses.

Association of short stature and obesity with cardio-metabolic risk factors in Iranian children and adolescents: the CASPIAN-V study.

PURPOSE: The object of the present study was to examine the relationship of short stature and obesity with cardio-metabolic risk factors in children and adolescents from Iran. METHODS: Present nationwide cross-sectional study was conducted as a part of the fifth survey of CASPIAN study on 7 to 18 years old children and adolescents from 30 provinces of Iran in 2015. Short stature and excess weight were defined as age and sex-specific height lower than 5th percentile and BMI higher than 85th percentile respectively. The multivariate logistic regression model was applied to assess the aim of the study. RESULTS: A total of 3844 children and adolescents (52.4%: boys, 72.2%: urban areas) with an average age of 12.45 ± 3.04 years were enrolled in this study. The prevalence of short stature, excess weight and combined-short stature and excess weight was estimated as 15.8%, 17.6% and 2.2%. Odds of abdominal obesity in children with only short stature (OR: 2.11, 95%CI: 1.59-2.80), only excess weight (OR: 17.38, 95%CI: 13.89-21.75) and combined-short stature and excess weight (OR: 22.83, 95%CI: 13.93-37.39) were higher than children with normal-height and weight. Moreover, odds of high BP and metabolic syndrome were further in the students with combined excess weight and short stature compared to the normal-height and weight group. CONCLUSION: We found that abdominal obesity, hypertension, and metabolic syndrome in short stature and obese children and adolescents were greater than those with normal-height and weight. Further prospective evaluations are required to clarify the association between short stature and cardio-metabolic risk factors.

Validity of continuous metabolic syndrome score for predicting metabolic syndrome; a systematic review and meta-analysis.

BACKGROUND: Nowadays, use of continuous metabolic syndrome (cMetS) score has been suggested to improve recognition of metabolic syndrome (MetS). The aim of this study was to evaluate the validity of cMetS scores for predicting MetS. METHODS: We searched the electronic databases included MEDLINE/PubMed, Embase, ISI Web of Science, and Scopus from 1 January 1980 to 30 September 2020. Observational studies on participants with different cMetS scores were included in this meta-analysis. The sensitivity, specificity, positive likelihood ratio (LR+), negative likelihood ratio (LR) and diagnostic odds ratio (DOR) with 95% CI were calculated. RESULTS: Ten studies involving a total of 25,073 participants were included. All studies had cross-sectional design. The pooled sensitivity and specificity of cMetS scores for predicting MetS were 0.90 (95% CI: 0.83 to 0.95) and 0.86 (95% CI: 0.83 to 0.89), respectively. Moreover, cMetS scores had the pooled LR+ of 6.5 (95% CI: 5.0 to 8.6), and a pooled (LR-) of 0.11 (95% CI: 0.063 to 0.21). The pooled DOR of cMetS scores to predict MetS were 57 (95% CI: 26 to 127). CONCLUSIONS: The high sensitivity and specificity of cMetS scores indicates that it has a high accuracy to predict the risk of MetS. Furthermore, the cMetS scores has a good ability to rule out healthy people. STUDY REGISTRATION: This study was registered as PROSPERO CRD42020157273.

Dermatological manifestations in hemodialysis patients in Iran: A systematic review and meta-analysis.

BACKGROUND: Dermatologic complications are common in patients with end-stage renal disease and also have a high diversity. OBJECTIVES: This meta-analysis reviews prevalence of dermatological manifestations among hemodialysis patients in Iran. MATERIALS AND METHODS: Using PubMed and NLM Gateway (for MEDLINE), Institute of Scientific Information (ISI), and SCOPUS as the main international electronic data sources, and Iran-Medex, Irandoc, and Scientific Information Database, as the main domestic databases with systematic search capability, we systematically searched surveys, papers, and reports on the prevalence of dermatological manifestations (until February 2016). Heterogeneity of reported prevalence's between studies was assessed using the Q test; overall prevalence of dermatological manifestations was estimated using random-effect meta-analysis model. RESULTS: We found 1229 records; from them, a total of eight studies comprising 917 hemodialysis patients were included. In all of studies, skin discoloration, pruritus and xerosis have the highest prevalence. According to random-effect meta-analysis model, the pooled prevalence of skin discoloration, pruritus, ecchymosis, xerosis, and half-and-half nail in hemodialysis patients were 48.03% (95% CI: 45.09-51.01), 52.85% (95%CI: 49.23-56.47), 19.88 (95% CI: 17.57-22.19), 51.14% (95% CI: 48.25-54.02), and 18.50% (95% CI: 16.0-21.0), respectively. CONCLUSIONS: his study shows that the prevalence of dermatological manifestations seems high among the hemodialysis patients in Iran, and skin discoloration, pruritus, and xerosis are more common.

Menopause and metabolic syndrome in the Middle East countries; a systematic review and meta-analysis study.

INTRODUCTION: Metabolic syndrome (MetS) prevalence that is associated with increasing risk of diabetes and cardiovascular diseases (CVD) has accelerated with age. Since, menopause is known as a partial cause of CVD accelartion with againg among women, determining the prevalence of MetS is important in this condition. We aimed to assess critically the prevalence rate of MetS among menopaused women in the Middle East Countries in this systematic review meta-analysis study. METHODS & MATERIALS: International webdata bases including Scopus, ISI web of Science and PubMed were systematically searched using Medical Subject Headings terms from January 2000 to February 2017. We included all cross-sectional conducted in the Middle East that reported prevalence of MetS in menopause status regardless of MetS definition. Quality assessment was considered for each included study. The pooled prevalence of MetS based on the Adult Treatment Panel III (ATP III) was estimated using random effect method due to between-study heterogeneity by STATA software, version 11.0 (StataCorp, USA). RESULTS: Within 60 studies, 21 and 17 studies were included in qualitative synthesis and meta-analysis respectively. The prevalence of MetS among menopaused women was estimated 54.87% (95% CI: 53.76-55.97) in the Middle East countries. In sub-group analysis based on country the prevalence rate of MetS in Iran and Turkey was estimated 58.78% (95% CI: 57.54-60.02), and 39.02% (95% CI: 36.57-41.47), respectively. CONCLUSIONS: MetS was highly prevalent as an alarming sign among menopaused women in the Middle East countries. Thus, it is an emergency requirement to promote healthy lifestyle. Also, early detection and treatment of women who reach menopause and are at great risk of developing MetS is necessary for prevention of diabetes and CVD in the region.
