Introduction: Gestational diabetes mellitus (GDM) and hypertensive disorders of pregnancy (HDP) are the principal causes of maternal morbidity and mortality. The maternal morbidity and mortality burden for Palestinian women is relatively high, suggesting a substandard quality of care. Therefore, an early diagnosis of GDM and gestational hypertension (GH) can improve prenatal care for pregnant women and improve pregnancy outcomes. Previous studies demonstrated that elevated Hb levels in the first trimester indicate possible pregnancy complications and should not only be considered as good iron status. However, ethnic differences could play a role in determining the magnitude of the association. We hypothesized that high Hb levels (≥12.5 g/dl) in the first trimester (6-13 gestational weeks, GW) are associated with increased risk of fasting blood sugar (FBS) ≥126 mg/dl, systolic blood pressure (SBP) ≥140 mmHg, and diastolic blood pressure (DBP) ≥90 mmHg among pregnant Palestinian women visiting prenatal clinics in Palestine. Methods: Medical records (N=5263) were reviewed for singleton pregnancies who had their first maternity care clinic visit (6-13 GW) at primary healthcare centers of the Palestinian Ministry of Health in the north of the West Bank in 2018 and 2019. Women were excluded if they had FBS ≥92 mg/dl, SBP ≥140 mmHg, DBP ≥90 mmHg, ultrasound-based gestational age >13 weeks, or who were previously diagnosed with diabetes mellites, GDM, hypertension, GH, taking drugs for these conditions, or were smoking during pregnancy. Hb levels in g/dl were divided to low (

Recognising health problems associated with CE/PS use can indicate how preventive programs should be directed towards adolescents. Unfortunately, research has not thoroughly investigated the health problems related to tobacco and caffeine products, the most socially acceptable CE/PS among Palestinian refugee adolescents.Methodology: In 2021, schoolchildren from five Palestinian refugee camps (N=271) aged 12-< 16 years agreed to give blood samples and to be interviewed to address the association between metabolic syndrome (MetS) and tobacco smoking, coffee, energy drinks (ED), black tea, and chocolate consumption. MetS was diagnosed based on International Diabetic Federation Criteria. To address the association, we used binary logistic regression models adjusted to age, gender, BMI, and central obesity.Results: The prevalence of MetS was [17 (6.3%)]; (7.4%) in males, (5.1%) in females. The prevalence of substance use was as follows: ED [163 (48.9%)], coffee [255 (76.6%)], black tea [295 (89.1%)], cigarette [35 (10.5%)], waterpipe [59 (17.7%)], and chocolate [309 (93.6%)], with male predominance. Cigarette smokers have increased central obesity (p-value=0.024), and decreased HDL-cholesterol (p-value=0.015) than non-smokers. Similar results were observed for waterpipe smokers besides the increased levels of triglycerides (p-value=0.01). ED consumers have increased central obesity (p-value=0.03) and fast blood sugar (p-value=0.003) than non-consumers. Chocolate consumers have decreased central obesity (p-value=0.008) and increased HDL levels (p-value=0.04) than non-consumers. ED consumers were significantly at higher risk of MetS (OR=9.97, p-value=0.019) than non-consumers and chocolate consumers were at lower risk of MetS (OR=0.14, p-value=0.046) than non-consumers. Waterpipe smokers were at a higher risk of having increased plasma triglycerides than non-consumers (OR=3.4, p-value=0.03).Conclusion: The high prevalence of ED consumption and waterpipe smoking in Palestinian refugee adolescents is problematic. Their use was associated with higher odds of MetS, dyslipidemia, and central obesity, which justifies greater attention.Keywords: refugee adolescents, metabolic syndrome, tobacco smoking, cognitive enhancers and psychostimulants, dyslipidemia, UNRWA

ED in Palestinian male students is a neglected health issue. We aimed to investigate the prevalence and the association between ED and cognitive enhancers, and psychostimulants use among An-Najah National University students (ANNU).Methods: In a cross-sectional study conducted in 2020 at ANNU, 1047 students completed anonymous surveys for cognitive enhancers practice, the Eating Attitude Test-26 (EAT-26), Sick, Control, One, Fat and FOOD (SCOFF) screening tests.Results: The prevalence of ED among ANNU students was 21.2% based on EAT-26 (17.1% in males, 23.8% in females) and 31.5% based on SCOFF (24.0% in males, 36.3% in females). The binary logistic regression revealed that students at risk to have ED were water-pipe smokers (OR: 1.471, p-value 0.047), especially males, while students who were less likely to have ED were males (OR: 0.341, p-value< 0.001), coffee users (OR: 0.581, p-value 0.014) and chocolate users (OR: 0.530, p-value 0.041) than nonusers. Moreover, the risk of ED increased with increasing body mass index (p-value< 0.01). Clinical medical students showed the lowest prevalence (11.1%) compared to preclinical (22.5%), health sciences (23.7%), and non-medical students (20.9%) (p-value 0.059).Conclusion: Our findings highlight water-pipe smoking as a significant health problem in males with ED, which may require unique treatment and prevention strategies. Moreover, coffee and chocolate consumption were associated with decreased risk of ED, only among males. The gender-gap in ED prevalence was very narrow compared to international results. These results prompt the need to focus on both genders in future studies instead of females. They also suggest the urgent need to address ED among Palestinian university students by educating students about mental health, identifying high-risk students, and offering easily accessible psychological help.Keywords: cognitive enhancers, psychostimulants, eating disorders, tobacco smoking, water-pipe smoking

A self-tuning regulator (STR) with multi-identification models and a minimum variance controller that utilizes fuzzy logic switching is presented. The STR employs recursive least squares algorithms with different order identification models to best model the plant at any given time interval, and an error minimization algorithm will select the one model that has the least identification error in comparison to the plant output. This controller design is applied to a synchronous machine in order to control the speed. The performance of the control system using the proposed scheme shows an overall improvement in comparison to those of existing stabilizers as well as classical STRs
