Association between omega-3 fatty acid intake and ADHD symptoms among early adolescents aged 10–12 years: a cross-sectional study in Palestine Safaa Muhanna, Hala Jaradat, Nadeen Toukhli, Omar H. Almahmoud International Journal of Adolescent Medicine and Health, 2025 Objectives Deficits in omega-3 fatty acids, particularly eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), have been implicated in attention-deficit/hyperactivity disorder (ADHD). These fatty acids are essential for neurodevelopment and cognitive functioning during childhood and early adolescence. The purpose of this study was to examine the association between ADHD symptoms and dietary omega-3 intake among Palestinian early adolescents aged 10–12 years, with particular attention to socioeconomic determinants. Methods A cross-sectional study was conducted with 211 participants (38 with ADHD, 173 without ADHD). Parents completed a culturally adapted Food Frequency Questionnaire (FFQ) to estimate intake of omega-3–rich foods (e.g., fish, nuts, seeds). ADHD symptoms were assessed by subtype, and socioeconomic factors were recorded. Group differences were tested, and logistic regression evaluated associations between omega-3 intake and ADHD symptoms. Results Children with ADHD reported significantly lower omega-3 intake (mean=0.60 ± 0.68) than their peers without ADHD (mean=0.89 ± 0.72; p<0.001). The hyperactive/impulsive subtype had the lowest intake (mean=0.42 ± 0.62). Logistic regression indicated that each unit increase in omega-3 intake was associated with a 45 % reduction in hyperactive/impulsive symptoms (OR=0.55, p=0.03). Adolescents’ age, gender, parental education, parental employment, and family income were significantly associated with children’s omega-3 intake (p<0.05). Conclusions Lower dietary omega-3 intake is associated with more severe ADHD symptoms, particularly in the hyperactive/impulsive subtype. Socioeconomic disparities further exacerbate nutritional deficiencies, with potential consequences for neurodevelopment and behavioral health. Public health interventions—such as school-based nutrition programs, caregiver education, and subsidies for omega-3–rich foods—may support mental health and cognitive development among children and early adolescents in resource-limited and conflict-affected settings.
Prevalence, awareness, and risk factors affecting hypertension according to 2017 American College of Cardiology and American Heart Association guidelines: A cross-sectional study from a developing country Imad Asmar, Omar Almahmoud, Maram Jaghama Journal of Hypertension, 2025 Background: Hypertension (HTN) is a chronic disease prevalent worldwide, with a significant increase in the number of people diagnosed with HTN. This study aimed to determine the prevalence and awareness of HTN among adults in Palestine according to the 2017 American College of Cardiology and American Heart Association guidelines, and to investigate the risk factors affecting HTN. Methods: A cross-sectional study was conducted between August 2024 and November 2024 among residents of West Bank Palestine. A total of 1420 adults aged 18 years and older were recruited using convenience sampling. Data were collected through blood pressure and anthropometric measurements of BMI and waist circumference. A questionnaire was used to gather sociodemographic information, HTN history, physical activity, antihypertensive drug use, and other family history information. Statistical analyses, including chi-square tests and binary logistic regression, were performed. Results: The prevalence of HTN in this study was 60%. Moreover, 46.4% of participants with HTN were unaware of their condition. Several factors were found to be independent predictors of HTN, including smoking [adjusted odds ratio (aOR): 8; 95% confidence interval (CI): 5.1–11.1], older age (aOR: 1.022; 95% CI: 1.01–1.04), and living in urban areas (aOR: 1.9; 95% CI: 1.4–2.5). Conversely, normal BMI (aOR: 0.6; 95% CI: 0.4–0.9) and moderate physical activity (aOR: 0.6; 95% CI: 0.6–0.8) were protective against the development of HTN. Conclusion: Three out of five adults in Palestine had HTN, and approximately half of them were unaware of their condition. The study findings indicate the urgent need for appropriate public health interventions to address awareness, early detection, and modifiable risk factors, which will greatly alleviate the regional HTN burden.
Summary of Needlestick Injuries Among Nursing Students and Related Factors A Narrative Review Imad Asmar, Omar Almahmoud, Ayat Abu Zahra, Nadeen Qattousah, Fatima Sumreen, et al. Infectious Diseases in Clinical Practice, 2025 During clinical training, student nurses are at a higher risk of blood-borne infections due to needlestick injuries (NSIs). Medical sharp instruments like syringe needles, stitches, puncture needles, scalpels, and ampoules can lead to sharp injuries by causing deep skin wounds that result in bleeding. Nursing students must know every facet of NSIs to safeguard themselves from the dangers. Nevertheless, due to their inexperience in handling needles and sharp items in a clinical setting, nursing students are more likely to suffer from NSIs than more seasoned nurses. This review aimed to determine how often and to what degree nursing students understood NSIs. A thorough search was carried out for relevant English research papers released from January 2013 to January 2024 in the databases of Science Direct, Scopus, PubMed, and CINAHL. The research focused on the prevalence, knowledge, and recognition of NSIs among nursing students and associated factors. This analysis showed that the high prevalence rate of NSIs varies widely between 6.2% and 67% worldwide and that nursing students have low to moderate awareness of them. The literature review emphasized many variables that might increase the frequency of NSIs, such as gender, time, education level, training location, characteristics of the injury, educational background, and workload.
Summary of Critical Care Nurses' Understanding, Adherence, and Barriers in Applying Ventilator-Associated Pneumonia Prevention Guidelines: A Narrative Review Imad Asmar, Omar Almahmoud, Aya Manassrah, Dalya Moqady, Raneen Abd Al Hamed, et al. Critical Care Nursing Quarterly, 2025 Both adults and pediatric patients who are on mechanical ventilation face high rates of mortality and morbidity due to ventilator-associated pneumonia (VAP), which is the most prevalent deadly hospital-acquired infection. Healthcare organizations provide evidence-based guidelines to help nurses decrease VAP in ICUs; however, there are obstacles to putting these guidelines into practice. An extensive investigation was conducted for pertinent English studies published from January 2014 to February 2024 in the databases of Science Direct, Scopus, PubMed, and CINAHL. The study centered on nurses’ understanding, adherence, and obstacles regarding introducing VAP prevention guidelines. The majority of ICU nurses have a basic to intermediate understanding of evidence-based methods to reduce VAP. The nurses in the ICUs typically followed the guidelines for preventing VAP about 60% of the time. A basic analysis of descriptive content identified the obstacles preventing critical care nurses (CCNs) from following VAP PGs. The obstacles were separated into 2 groups: barriers related to nurses (such as education, experience, and training) and barriers related to the work environment (such as lack of supplies, staffing shortage, lack of policies, and ineffective supervision). To improve their skills, CCNs should get frequent updates on courses and seminars related to the VAP PG implementation. Healthcare administrators must be aware of these obstacles and implement work procedures that help CCNs overcome them if they want to increase compliance.
