Introduction: Iron deficiency anemia is the most common type of anemia according to the World Health Organization. Females are more likely to be affected than males. There are several factors causing iron deficiency anemia, such as increased loss of iron, decreased intake of iron, and increased utilization of iron. There are limited research studies evaluating the risk factors that cause anemia among female medical students in Saudi Arabia. For this, the study aimed to identify the prevalence of undiagnosed iron deficiency anemia (IDA) among young female university students and to identify if there is any correlation between IDA and several factors including dietary habits, psychological stress, anxiety status, and body mass index., Materials and Methods: A cross-sectional observational study was performed between October 2022 and December 2022 with a sample of 100 healthy female students aged between 19 and 23 years, who were studying at the medical colleges of Umm Al-Qura University, Saudi Arabia. Blood samples were collected to perform complete blood count and iron profile tests. Also, a survey was done to find correlation between iron deficiency anemia and dietary intake, drinks, stress, anxiety, and body mass index (BMI). Independent t-test or Mann-Whitney U test were used to compare values for non-anemic with anemic participants, and linear regression tests were used to analyze differences between non-anemic and anemic participants' dietary intake factors and stress and anxiety scores. The level of significance was set at p<0.05., Results: The findings represent an overall prevalence of iron deficiency anemia in female medical students based on the lab finding results. Thus, students were divided into two following groups: anemic (13%) with hemoglobin (Hb) concentration <12 g/dL and non-anemic (84%) with Hb concentration ≥12 g/dL. When comparing the two groups, results showed significant differences in the majority of RBC indices (hematocrit {HCT}, mean corpuscular volume {MCV}, mean corpuscular hemoglobin {MCH}, red cell distribution width {RDW}) and iron profiles, p-value was <0.05. On evaluation of the different types of food consumption, the mean iron intake was around 7 mg/day, and in 65% of the participants, it was below the estimated average requirement (EAR) of iron (8.1 mg/dL). The perceived stress scale (PSS) shows that 63% of the participants experienced moderate stress and 58% reported severe anxiety by the generalized anxiety disorder (GAD) scale. In multiple linear regression, iron was positively associated with hemoglobin concentrations, whereas stress scores were negatively associated with hemoglobin concentrations., Conclusion: There is a relatively low prevalence of anemia and most of it was found of the microcytic type, indicating that this condition is a common health issue among local female college students. There was no independent association between stress or anxiety and hemoglobin levels., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2023, Almasmoum et al.)

Introduction The COVID-19 pandemic has been a major public health and economic issue worldwide. Even though vaccines have been developed to reduce the spread of the infection, treating patients remains a significant challenge. This study aims to measure the perceptions of Saudis toward participating in the COVID-19 Convalescent Plasma Clinical Trial. Method A cross-sectional study measuring the perceptions of Saudis toward participating in the COVID-19 Convalescent Plasma Clinical Trial was conducted with participants who had recovered from COVID-19. The study used an online questionnaire covering variables related to demographics, awareness, attitudes, perceptions, and plans for improvement. Results A sample of 1,051 participants participated in the questionnaire. A total of 85% had recovered from COVID-19, only 2.76% had participated in clinical trials before, and 83.44% would participate if they were advised or knew about them. The participants showed a high level of education, with 88% having obtained a degree and most used social media. The results can be biased toward the participants who get their knowledge from social media and hope to learn about things on social media. The gap in knowledge about clinical trials among the participants indicated that certain age groups could be targeted through channels where they communicate the most. Conclusion Engaging the community in clinical trials and educating others about their value by sharing experiences would help promote clinical trials and activate donations., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2023, Al Eissa et al.)

Background: The World Health Organization declared coronavirus disease 2019 (COVID-19) responsible for a catastrophic global pandemic. The complexity of COVID-19 is centred on the unpredictable course of the disease, which can rapidly develop from patients being asymptomatic to having life-threatening symptoms. The unpredictable disease severity of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection has been a major problem facing the healthcare system during the pandemic. Identifying the laboratory biomarkers would help predict SARS-CoV-2 pathogenicity. This study focused on the previous literature regarding three laboratory biomarker profiles: haematological, inflammatory, and biochemical biomarkers., Methods: A retrospective study of COVID-19 patients was conducted between May 2020 and September 2020 to determine the predictors of hospitalization (severity) in COVID-19 patients. Patients were divided into two groups: those admitted to an intensive care unit (ICU, severe) and those admitted to a non-ICU (stable). Patients' data were obtained from their medical records at Al Noor Specialist Hospital and East Arafat Hospital in Saudi Arabia., Results: A total of 487 patients with COVID-19, including 304 males and 183 females, were investigated in this study. A total of 217 patients were admitted to the ICU. Patients admitted to the ICU had a higher prevalence of chronic comorbidities than non-ICU patients. D-dimer, white blood cells (WBC), neutrophils, ferritin, C-reactive protein (CRP), lactate dehydrogenase (LDH), alanine aminotransferase (ALT), and aspartate aminotransferase (AST) were more elevated in patients admitted to the ICU compared to non-ICU patients., Conclusion: Chronic comorbidities are a significant predictor for admission to the ICU. Moreover, tests for D-dimer, WBC, neutrophils, lymphocytes, CRP, LDH, and ALT could be used to predict patients' admission to the ICU., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2022, Alsafi et al.)
