Crassocephalum rubens (Juss Ex Jacq) leaf diets ameliorate systemic oxidative stress and tissue damage in a Wistar rat model.

The capacity of Crassocephalum rubens (Juss Ex Jacq) leaf to protect against systemic oxidative stress was evaluated in N-methyl-N-nitrosourea (MNU) - intoxicated rats fed at various inclusion rates for a period of twelve (12) weeks. Major organs and tissues were then assessed for indices of lipid peroxidation and oxidative stress. Crassocephalum rubens leaf significantly (p < .05) sustained the activities of superoxide dismutase and catalase with significant decrease in lipid peroxidation in MNU-intoxicated animals, particularly at 5% and 10% inlusion rates. The dietary inclusion also prevented significant changes in hematological parameters such as neutrophil and lymphocyte counts. It also reduced the severity of histologic damages such as necrosis, epithelial degeneration, inflammatory cell infiltration and other pathological changes to major organs. These results indicate that regular consumption of C. rubens leaf, prevents the deleterious biologic effects of the damaging reactive oxidative species (ROS). PRACTICAL APPLICATIONS: Crassocephalum rubens leaf has potential for development into a nutraceutical or functional food for chemoprevention and management of neurodegenerative diseases and other diseases associated with systemic oxidative stress, This is because its inclusion in the diet has attenuated lipid peroxidation, sustained the activity of antioxidant enzymes and mitigated deleterious changes in blood composition and tissue architecture resulting from exposure to a chemical carcinogen.

Risk Factors of COVID-19 Critical Outcomes in the Eastern Mediterranean Region: Multicountry Retrospective Study.

BACKGROUND: The establishment of empirical evidence in the Eastern Mediterranean Region necessitates the implementation of wide-scale studies to describe the demographic, clinical features, and severity profile of patients with COVID-19. OBJECTIVE: This study aims to assess the patterns of COVID-19 severity and mortality in seven countries, and to determine the risk factors of COVID-19 severity and mortality. METHODS: This multicountry study was based on a retrospective review of medical records of hospitalized patients confirmed to have COVID-19. This study includes data from Iraq, Pakistan, Sudan, Somalia, Morocco, Egypt, and Yemen. All demographic and clinical data were extracted from hospital records (paper files) by trained data collectors. RESULTS: A total of 4141 patients were included in this study from seven countries. Comorbidities were reported by nearly half of the patients, with hypertension (n=1021, 24.7%) and diabetes (n=939, 22.7%) being the most common. Older age, diabetes mellitus, hypertension, and heart diseases were significantly associated with COVID-19 severity and mortality. Ever smoking and renal diseases were significantly associated with severity but not mortality, while male gender, respiratory diseases, and malignancy were significantly associated with mortality but not severity. CONCLUSIONS: The study confirms the role of comorbidities and demographic features on the severity and mortality of COVID-19. Understanding the contributing factors ensures attentive care and informs clinical management of patients with poorer prognoses in the early stages of diseases.

Survival analysis of all critically ill patients with COVID-19 admitted to the main hospital in Mogadishu, Somalia, 30 March-12 June 2020: which interventions are proving effective in fragile states?

OBJECTIVES: To determine risk factors for death in patients with coronavirus disease 2019 (COVID-19) admitted to the main hospital in Somalia, and identify interventions contributing to improved clinical outcome in a low-resource and fragile setting. METHODS: A survival analysis was conducted of all patients with COVID-19 admitted to the main hospital in Somalia from 30 March to 12 June 2020. RESULTS: Of the 131 patients admitted to the hospital with COVID-19, 52 (40%) died and 79 (60%) survived. The main factors associated with the risk of in-hospital death were age ≥60 years {survival probability on day 21 was 0.789 [95% confidence interval (CI) 0.658-0.874] in patients aged <60 years vs 0.339 (95% CI 0.205-0.478) in patients aged ≥60 years}, cardiovascular disease [survival probability 0.478 (95% CI 0.332-0.610) in patients with cardiovascular disease vs 0.719 (95% CI 0.601-0.807) in patients without cardiovascular disease] and non-invasive ventilation on admission (patients who were not ventilated but received oxygen were significantly more likely to survive than patients who were ventilated; P<0.001). CONCLUSION: Considering the risk factors (age ≥60 years, presence of cardiovascular disease and use of non-invasive ventilation) is critical when managing patients with severe COVID-19, especially in low-resource settings where availability of skilled healthcare workers for critical care units is limited. These findings also highlight the importance of use of medical oxygen for severely ill patients, and the critical aspect of deciding whether or not to ventilate critical patients with COVID-19 in order to improve clinical outcome.

Preliminary findings of COVID-19 infection in health workers in Somalia: A reason for concern.

BACKGROUND: Somalia, a country with a long history of instability, has a fragile healthcare system that is consistently understaffed. A large number of healthcare workers (HCWs) have become infected during the coronavirus disease-19 (COVID-19) pandemic. OBJECTIVE: This report presents the preliminary findings of COVID-19 infection in Somali HCWs, the first of such information from Somalia. METHODS: This preliminary retrospective study analysed available data on infection rates among Somali HCWs. RESULTS: As of 30 September 2020, 3700 cases of COVID-19, including 98 deaths, had been reported in Somalia; 191 (5%) of these cases were HCWs. During the first 180 days of the outbreak, 311 HCWs were tested for COVID-19 and 191 tested positive (positivity rate: 61%). During the epidemic's peak, HCWs represented at least 5% of cases. Of the 191 infected cases, 52 (27%) were doctors, 63 (33%) were nurses, seven (4%) were laboratory technicians, and 36% were other staff. CONCLUSION: More information must be sought to put measures in place to protect the health and safety of HCWs in Somalia's already understaffed and fragile healthcare system.

Survival analysis of all critically ill patients with COVID-19 admitted to the main hospital in Mogadishu, Somalia, 30 March to 12 June 2020: what interventions are proving effective?

OBJECTIVESTo determine risk factors for death in patients with COVID-19 admitted to the main public sector hospital in Somalia and identify interventions contributing to improved clinical outcome in a low-resource and fragile setting. SETTINGMain public sector tertiary hospital in Mogadishu, Somalia. PARTICIPANTSAll 131 laboratory-confirmed COVID-19 patients admitted to the main public tertiary hospital in Somalia between 30 March and 12 June 2020. MAIN OUTCOME MEASURESWe extracted demographic and clinical data from hospital records of all 131 COVID-19 patients admitted to hospital until their death or recovery. We used Kaplan-Meier statistics to estimate survival probabilities and the log-rank test to assess significant differences in survival between groups. We used the Cox proportional hazard model to estimate likelihood of death and assess the effect of risk factors on survival. RESULTSOf the 131 patients, 52 (40%) died in the hospital and 79 (60%) survived to discharge. The factors independently associated with increased risk of in-hospital death were: age [≥] 60 years - survival probability on day 21 in patients < 60 years was 0.789 (95% confidence interval (CI): 0.658-0.874) compared with 0.339 (95% CI: 0.205-0.478) in patients [≥] 60 years; cardiovascular disease (survival probability 0.478 (95% CI: 0.332-0.610) in patients with cardiovascular disease compared with 0.719 (95% CI: 0.601-0.807) in patients without cardiovascular disease); and non-invasive ventilation on admission - patients who were not ventilated were significantly more likely to survive than those who were (P < 0.001). CONCLUSIONOur study, which includes the largest cohort of COVID-19 patients admitted to a single hospital in a sub-Saharan African country, confirms that underlying conditions and age are associated with increased risk of in-hospital death in patients with COVID-19. Our results show the advantage of medical oxygen over non-invasive ventilation in the treatment of patients with severe COVID-19 symptoms.
