Pregnancy-Related Complications and Incidence of Atrial Fibrillation: A Systematic Review.

Pregnancy-related complications are associated with a higher risk of various incident cardiovascular diseases, but their specific potential relationship with incident atrial fibrillation (AF) is less clear. This systematic review summarises the available evidence from observational studies which have examined associations between pregnancy-related complications and the risk of AF. MEDLINE and EMBASE (Ovid) were searched for studies between 1990 to 10 February 2022. Pregnancy-related complications examined included hypertensive disorders of pregnancy (HDP), gestational diabetes, placental abruption, preterm birth, small-for-gestational-age and stillbirth. Study selection, data extraction and quality assessment were completed independently by two reviewers. Narrative synthesis was used to evaluate the results of the included studies. Nine observational studies were included, with eight eligible for narrative synthesis. Sample sizes ranged from 1839 to 2,359,386. Median follow-up ranged from 2 to 36 years. Six studies reported that pregnancy-related complications were associated with a significantly increased risk of incident AF. Hazard ratios (HRs) (95% confidence intervals) for the four studies that evaluated HDP ranged from 1.1 (0.8-1.6) to 1.9 (1.4-2.7). For the four studies that evaluated pre-eclampsia, HRs ranged from 1.2 (0.9-1.6) to 1.9 (1.7-2.2). Current evidence from observational studies suggests pregnancy-related complications are associated with a significantly higher risk of incident AF. However, only a small number of studies examining each pregnancy-related complication were identified, and considerable statistical heterogeneity was observed. Further large-scale prospective studies are required to confirm the association between pregnancy-related complications and incident AF.

Awareness, knowledge and perception of electronic cigarettes among undergraduate students in Jazan Region, Saudi Arabia.

The use of electronic cigarettes (e-cigarettes) has steadily grown over the past few years, rising in popularity amongst young adults, especially. Owing to the perception that e-cigarettes are less harmful than conventional cigarettes, some people have resorted to using them as a means of quitting cigarette smoking. This study aimed to assess the awareness, knowledge, perception and use of e-cigarettes among Jazan University students in Saudi Arabia. An observational cross-sectional study was conducted with 775 students. Using stratified random sampling to recruit study participants, the dataset tabling the use of e-cigarettes, as well as knowledge, perception and awareness was collected using a translated and culturally adapted structured Arabic questionnaire. Our results showed that 21.0% of the participants used e-cigarettes and 35.1% of them used them to quit smoking. E-cigarette use was mostly reported by students from the College of Medical Applied Sciences (31.7%). The overall knowledge score was 3.9, with a standard deviation of 1.3 for the score range from zero to seven. About half of the participants correctly identified e-cigarettes as not less addictive' than cigarettes. However, 70.2% of students failed to identify e-cigarettes as a source of second-hand exposure to nicotine. About two-thirds of the sample believed that e-cigarettes could adversely affect health. The perception of using e-cigarettes for smoking cessation was not significantly associated with e-cigarette use. In conclusion, the prevalence of e-cigarette use was similar to that reported in the literature. However, Jazan University students failed to identify the health risks associated with e-cigarette use. Therefore, a strategy to enhance students' awareness of the benefits and harms of e-cigarettes is needed.

Consumption habits of pregnant women in the Jazan region, Saudi Arabia: a descriptive study.

OBJECTIVE: Maternal nutritional habits are critical for the health of both mother and offspring. Postpartum outcomes for mother and infant are strongly influenced by the mother's nutritional status. Information about consumption habits among pregnant women in Saudi Arabia is scarce. Thus, this study aims to describe the consumption habits of pregnant women in the Jazan region, Saudi Arabia. RESULTS: Meat, fish, and fruits were consumed by 97%, 86%, and 90% of the sample. Sugary desserts, fast food, and canned food were consumed by 90%, 81%, and 71% of the sample. Caffeine, juices, and milk were consumed by 75%, 92%, and 81% of the sample. Previous percentages show general higher consumption habits of food and beverages. Over-the-counter medication was used by only 17%. Folic acid, iron, and calcium use by 77%, 64%, and 58% of the sample, respectively. These percentage shows conservative use of Over-the-counter medication and sub-optimal use of important dietary supplements. Moreover, there was a positive association between caffeine intake and trimesters. Furthermore, there was negative association between education level and fish intake. Finally, canned foods consumption was higher among low income pregnant women.

Refractive Error among Male Primary School Students in Jazan, Saudi Arabia: Prevalence and Associated Factors.

BACKGROUND: Refractive error is a common and serious eye disorder that affects more than 153 million people globally. The aim of this study was to estimate the prevalence and pattern of refractive error among male primary school children in Jazan region, Saudi Arabia. METHODS: A cross-sectional study was conducted among a randomly selected group of 395 students (aged 6-14 years) in Jazan region, Southwest Saudi Arabia. An optometrist and medical students assessed the refraction error using an autorefractor, a Snellen E chart and retinoscopy. RESULTS: The overall prevalence of uncorrected refractive error in either eye was, 22% higher among rural students. The most prevalent refractive error was hyperopia (32.2%) followed by myopic astigmatism (31%) then myopia (17.2%). Next were hyperopic astigmatism (16.1%) and mixed astigmatism (3.5%). The following variables were associated with a higher risk of refractive errors and myopia: living in rural areas, having parents with refractive errors, spending more time on electronic devices and shorter visual distances. CONCLUSION: Refractive error was highly prevalent among primary school children in Jazan, Saudi Arabia. The rural students were more affected by refractive errors, mainly hyperopia. The preschool vision test should be reconsidered, and a periodic vision examination should be applied to detect vision problems as early as possible.
