Risk factors associated with in-hospital mortality patients with COVID-19 in Saudi Arabia.

Risk factors for in-hospital mortality of COVID-19 patients in Saudi Arabia have not been well studied. Previous reports from other countries have highlighted the effect of age, gender, clinical presentation and health conditions on the outcome of COVID-19 patients. Saudi Arabia has a different epidemiological structure with a predominance of young population, which calls for separate study. The objective of this study is to assess the predictors of mortality among hospitalized patients with COVID-19 in Saudi Arabia. This is a retrospective observational cohort study of hospitalized adult COVID-19 patients at two tertiary hospitals in Saudi Arabia between May to July 2020. Electronic charts were retrospectively reviewed comparing survivors and non-survivors in terms of demographic and clinical variables and comorbid conditions. A total of 564 hospitalized patients with COVID-19 were included in the study. The overall in-hospital mortality rate was 20%. The non-survivors were significantly older than survivors (59.4 ± 13.7 years and 50.5 ± 13.9 years respectively P< 0.001). Diabetes mellitus, hypertension, heart failure and ischemic heart disease were more prevalent among non-survivors (P< 0.001). The mean values of glycosylated hemoglobin HgA1C, D-dimer, ferritin, lactate dehydrogenase LDH, Alanin aminotransferase ALT and creatinine were significantly higher among non-survivors (P < 0.05). Multivariate logistic regression analysis revealed that age (aOR = 1.04; 95% CI 1.02-1.08; P < 0.01), chronic kidney disease (aOR = 4.04; 95% CI 1.11-14.77; P < 0.05), acute respiratory distress syndrome ARDS (aOR = 14.53; 95% CI 5.42-38.69; P < 0.01), Mechanical Ventilation (aOR = 10.57; 95% CI 5.74-23.59; P < 0.01), Shock (aOR = 3.85; 95% CI 1.02-14.57; P < 0.05), admission to intensive care unit (ICU) (aOR = 0.12; 95% CI 0.04-0.33; P < 0.01) and length of stay (aOR = 0.96; 95% CI 0.93-0.99; P < 0.05) were significant contributors towards mortality. The in-hospital mortality rate of COVID-19 patients admitted to tertiary hospitals in Saudi Arabia is high. Older age, chronic kidney disease and ARDS were the most important predictors of mortality.

Cardiovascular Risk Factors Among Patients Infected with COVID-19 in Saudi Arabia.

BACKGROUND: Coronavirus disease (COVID-19) is a global pandemic with more than 60 million cases worldwide and over 1.5 million deaths by March 2021. Its outbreak has caused a huge burden on healthcare systems all over the world. Several studies in the medical literature have suggested that patients with underlying cardiovascular disease (CVD) are at higher risk for developing severe symptoms, poor prognosis, and high mortality rates. The aim of this study was to assess the prevalence of CVD risk factors among COVID-19 patients based on the Framingham risk score (FRS), and to evaluate the association of CVD risk factors with clinical outcomes. PATIENTS AND METHODS: In this retrospective cross-sectional study, we identified 264 confirmed cases with COVID-19 at King Saud University Medical City in Riyadh, Saudi Arabia. Patients aged 18-80 years were included, and their electronic records were reviewed. They were classified into low, intermediate, and high risk of CVD according to FRS classification. RESULTS: Two-hundred-six patients (67% male) were included in this study. The mean age was 55.3 ± 15.1 years. Most patients had comorbidities: the most common were hypertension (48.1%), diabetes (45.1%), and ischemic heart disease (11.2%). More than half required intensive care admission, and 58 (28.2%) patients died. Pneumonia was the most frequently observed complication (85%), followed by mechanical ventilation (28.3%) and acute kidney injury (27.7%). Age, male gender, hypertension, and diabetes mellitus showed significant differences between FRS categories, and were associated with intermediate and high-risk groups of FRS (p < 0.05). Pneumonia and length of stay were associated with the Intermediate risk group of FRS. CONCLUSION: Cardiovascular disease risk factors are prevalent in Saudi patients infected with COVID-19. FRS could be a useful tool to identify CVD risk factors among COVID-19 patients and predict a complicated course.

Indications for enucleation and evisceration in a tertiary eye hospital in Riyadh over a 10-year period.

BACKGROUND: Enucleation and evisceration are eye removal procedures considered as palliative treatment when all other therapeutic options are exhausted. OBJECTIVE: Describe the causes and histopathological findings leading to enucleation/evisceration, and correlate the clinical findings with the histopathological findings. DESIGN: Retrospective, descriptive study. SETTINGS: Tertiary care hospital, Riyadh, Saudi Arabia. PATIENTS AND METHODS: The medical records of patients who underwent enucleation or evisceration from February 2005 to May 2015 were reviewed. Patients were classified into two categories based on indications of surgery: traumatic and nontraumatic. Causes of ocular injury in the traumatic group were documented, and the histopathological findings were reviewed for the nontraumatic cases. MAIN OUTCOME MEASURE(S): Number of enucleation and evisceration surgeries and their causes and histopathological findings. RESULTS: One hundred ten patients underwent evisceration (n=69, 63%) and enucleation (n=41, 37%). Causes were traumatic in 38 (35%) and nontraumatic in 72 (65%). The median age was 50 years and there were 64 men and 46 women. Postoperative endophthalmitis was the most common indication for surgery (n=24, 21.8%), followed by painful blind eye (n=22, 20%). Ocular trauma was more predominant in men (n=29, 76%) than in women (n=9, 24%), and the leading mechanism of trauma was metallic nail injuries (n=6, 15.8%). In the nontraumatic group, endophthalmitis was the most common histopathological finding (n=25, 34.7%). CONCLUSIONS: The majority of the eye enucleation/evisceration surgeries were due to nontraumatic causes, especially postoperative infections. However, severe eye trauma was still a main indication for this destructive procedure. Guidelines are needed to decrease the incidence/severity of work-related eye injuries and to detect and manage eye infections earlier and more promptly. LIMITATIONS: Retrospective study, in one hospital in one area; therefore, results cannot be generalized.
