The association of metabolic risk factors with ischemic heart disease and heart failure in Saudi Arabia - A cross sectional study.

Background: Cardiovascular diseases (CVDs) are the leading non-communicable cause of morbidity and mortality worldwide. This study aimed at determining the association of metabolic risk factors with ischemic heart disease (IHD) and heart failure (HF). Methods: A cross-sectional study including 104 participants was conducted in three major hospitals between October 2020 and October 2021. All adult patients of either gender, over the age of 35, attending the CVD screening program at the family medicine clinics of the hospitals were included in the study. The physician collected demographic details, history of CVD, diabetes or hypertension, and current medication. Each patient's body mass index (BMI) was calculated, electrocardiogram (ECG) and blood tests were done. Univariate and multivariate logistic regressions were checked. Results: The mean age of the participants was 47.6 (SD = 13.5) years. Diabetes and hypertension had increased odds of IHD by 129 (CI = 6.20 - 2698.42, P = 0.002) and 195 (CI = 13.87 - 2743.11, P < 0.001) times, respectively. Diabetes mellitus (Chi2 = 11.93, P < 0.001) and hypertension (Chi2 = 14.74, P < 0.001) had significant association with HF. Dyslipidemia was significantly associated with IHD (OR = 12.41, CI = 1.15 - 134.12, P = 0.038) and high-grade HF (OR = 14.91 CI = 3.61 - 61.40, P < 0.001). Conclusion: Age, dyslipidemia, diabetes, hypertension, and left ventricular hypertrophy have significant association with IHD or HF among the study population.

ABO in Correlation to the Requirement of Mechanical Ventilation and Mortality in Critically Ill Patients With COVID-19.

BACKGROUND: Coronavirus disease 2019 (COVID-19) is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that was first discovered in December 2019 and turned to be pandemic in early March 2020. We aimed to describe the dominant ABO group and outcomes of critically ill patients (respiratory failure requiring mechanical ventilation and mortality) in a Saudi Arabian setting. METHODS: We conducted an observational, analytic cross-sectional, retrospective study in a tertiary care hospital. Around 90 candidates tested positive for COVID-19 were enrolled in this study during admission to critical care unit between May 2020 and September 2020. Blood group was detected in all patients included in the study during admission to critical care unit. RESULTS: In this study, data of 90 patients with COVID-19 admitted to critical care unit were collected. Some prevalent medical conditions were collected, in which hypertension (64.2%) and diabetes mellitus (58.9%) were the most reported comorbidities among patients and there was no significant difference between groups. Most of the sample had blood group of O (45.6%), while the least group was AB (5.6%). Patients with blood group of A/AB showed the highest mortality vs. group O/B (32% vs. 18.5%) with significant P value of 0.001. Patients of groups A/AB had higher risk for intubation than O/B groups (52.0% and 49.2%, respectively; confidence interval of 0.44 - 2.8 with insignificant P value of 0.055). Length of stay in critical care unit was significantly higher in group A/AB with a mean course of 18.20 days in comparison to group O/B with a mean course of 12.63 days (P = 0.033). CONCLUSION: Our data indicate that critically ill patients with COVID-19 with blood group A/AB are at increased risk of mortality and length of stay in critical care unit, with insignificant requirement of mechanical ventilation when compared with patients with blood group O/B. Future larger studies are needed to validate and understand the underlying mechanisms.

Knowledge about cervical cancer early warning signs and symptoms, risk factors and vaccination among students at a medical school in Al-Ahsa, Kingdom of Saudi Arabia.

BACKGROUND: Cervical cancer is the second most common cancer among females and also the most preventable. In the literature there is abundant evidence that awareness regarding cervical cancer and its prevention is low in the developing countries. Medical students are the future health professionals and can play an important role in increasing awareness among the general population. To assess the knowledge regarding symptoms, risk factors and prevention of cervical carcinoma among medical students in th Kingdom of Saudi Arabia, the present study was planned. MATERIALS AND METHODS: This cross-sectional study was conducted using a self-administered questionnaire with students at the College of Medicine, King Faisal University, Al-Ahsa, KSA, from December 2012 to May 2013. RESULTS: The responses of 188 students (males 111, females 77) in their second, third, fourth, and fifth years were recorded and used in the data analysis. The majority of the students were not aware of the early warning signs, symptoms and risk factors. On average, only 43.7% males and 56% of females were aware about the early signs and symptoms whereas 51.4% males and 57.8% females had knowledge about the risk factors of cervical cancers. Some 55% males and 46.8% females were unable to select the correct answer regarding human papilloma virus (HPV) infection as the cause of cervical cancer. Majority of the students (67%) were not aware about the availability of vaccine against HPV. CONCLUSIONS: Lack of knowledge regarding early signs and symptoms, risk factors and prevention of cervical cancer was observed in the present study.
