COVID-19 is thought to be the most significant public health threat the modern world has encountered. Health care workers (HCWs) face enormous pressure due to work overload, negative emotions, exhaustion, lack of contact with their families, and risk of catching the infection and death. This study aims to assess the level of stress perceived by HCWs and possible associated factors during the COVID-19 outbreak in Palestine. A cross-sectional sample of 430 frontlines HCWs was conducted using an online self-reported questionnaire. HCWs’ stress from the COVID-19 outbreak, factors that increase stress, and the activities that reduced stress were assessed. Chi-square test was used to compare between a categorical variable and the study outcome; associations are presented as odds ratios (OR) and confidence intervals (95% CI) with 0.05 significance level. Al-Najah National University institutional review board granted ethics approval. Most respondents (74.0%) reported high-stress levels during the outbreak. Fear of transmitting the virus to family was the most stressful factor (91.6%). HCWs who did not have training on the outbreak response were more likely to have high-stress levels (OR = 2.7 [95% CI = 1.7-4.4], P < .001). Those with high stress reported being disappointed (OR = 2.4 [95% CI = 1.5-3.6], P < .001), and strongly considered taking sick leave (OR = 3.9 [95% CI = 1.9-7.9], P < .001). HCWs are under tremendous stress, given the ongoing COVID-19 pandemic. Understanding the psychological impact of the outbreak on HCWs and the activities that mitigate the stress is crucial to guide policies and interventions that can maintain psychological well-being.

Background: Chronic kidney disease (CKD) is a global public health concern and diabetes is one of the main risk factors for its occurrence and progression. The aim of this research is to determine the prevalence of chronic kidney disease in a cross-sectional population of patients with type 2 diabetes in primary health centers in North West Bank.Methods: Patient data including patient characteristics, creatinine level, blood pressure, HbA1c, and hypertension and period of diabetes were obtained from primary health care centers. The eGFR has been determined using the CKD-EPI equation. CKD was staged according to the 2012 Kidney Disease Improving Global Outcomes Framework (KDIGO) guideline. Both univariable and multivariable statistical analysis was conducted using SPSS.Results: The prevalence of chronic kidney disease among diabetic adults in North West Bank was found to be 23.6% (95% CI: 19.4–28.1%) divided as follows: 19.7% had stage 3 CKD, 2.6% had stage 4 CKD and 1.3% had stage 5 CKD. In multivariable logistic regression, CKD was significantly associated with Age ≥ 60 years [adjusted OR: 3.2, 95% CI: 1.8–5.9], hypertension [adjusted OR: 5.7, 95% CI: 2.2–15.2], and smoking [adjusted OR: 2.3, 95% CI: 1.3–4.2].Conclusions: CKD is very prevalent among diabetic adults in Palestine. Co-morbid hypertension, smoking and older age has been shown to increase the risk of developing CKD. Extensive screening for diabetic patients to diagnose CKD at an early stage and to follow more aggressive treatment methods for diabetes as well as other important risk factors, especially hypertension and smoking, is recommended.

Objectives: E-cigarettes have gained popularity, especially among young adults. This study aims to determine the prevalence of e-cigarette smoking, assess knowledge and attitudes and identify associated factors among Palestinian university students. Design: A cross-sectional study. Setting and participants: The study was conducted among Palestinian university students in early 2023. A self-administered questionnaire was used to survey 1792 students from six Palestine universities in the West Bank. The questionnaire covered various aspects, including sociodemographic information, daily habits, exposure to smoking, attitudes and knowledge about e-cigarettes. Data were analysed using descriptive statistics, χ 2 tests and multivariate regression analysis. Results: The study revealed a high prevalence of tobacco use (41.2%), with e-cigarette use prevalent among 19.7% of participants. Knowledge about e-cigarettes was suboptimal, with misconceptions regarding their safety and health effects. Negative attitudes towards e-cigarettes were common, and students with negative attitudes were more likely to use e-cigarettes (aOR=2.6, 95% CI: 1.9 to 3.6). Gender (aOR=2.1, 95% CI: 1.4 to 3.0), waterpipe smoking (aOR=4.5, 95% CI: 3.2 to 6.3), physical inactivity (aOR=1.4, 95% CI: 1.1 to 1.9), high coffee consumption (aOR=1.6, 95% CI: 1.1 to 2.3), spending time with friends (aOR=2.4, 95% CI: 1.5 to 3.7), having a mother who is a smoker (aOR=1.5, 95% CI: 1.1 to 2.2) and having a friend who uses e-cigarettes (aOR=1.5, 95% CI: 1.1 to 2.1) were significantly associated with e-cigarettes use. Conclusions: E-cigarette use is a growing concern among Palestinian university students. Combating this trend should include educational initiatives, social interventions and policy measures to promote informed decision-making and discourage e-cigarette use. Comprehensive tobacco control programs considering various tobacco and nicotine products and involving multiple stakeholders are warranted.

Current studies about the long-term effects of COVID-19 show a wide range of symptoms. This prospective cohort study aimed to find the incidence of long-COVID symptoms and the associated risk factors. We followed 669 confirmed COVID-19 patients. Sociodemographic and clinical data were extracted from medical records and collected via semi-structured telephone interviews on days 10, 30, 60, and 90. The incidence of long-COVID symptoms was 41.6% (95% CI 37.8–45.4%). Females [aOR = 1.5 (95% CI 1.1–2.3)], the elderly [aOR = 4.9 (95% CI 2.0–11.3)], and those who required hospitalization [aOR = 5.0 (95% CI 1.3–3.7)] were at a higher risk of developing long-COVID. Patients with dyspnea at day 10 [aOR: 2.4 (95% CI 1.6–3.7] and fatigue at day 60 [aOR: 3.1 (95% CI 1.5–6.3] were also at risk. While non-vaccinated patients were almost seven times more likely to report long-COVID symptoms than vaccinated patients [aOR: 6.9 (95% CI 4.2–11.3)]. In conclusion, long-COVID was common among COVID-19 patients, with higher rates among females, older age groups, hospitalized patients, and those with dyspnea and fatigue, while vaccination provided protection. Interventions should educate health professionals, raise general public awareness about the risks and consequences of Long COVID, and the value of vaccination.
