Arterial Oxygen Saturation and other Clinical Predictors of Survival in Patients with Covid-19: A Review of Cases in a Tertiary Care Hospital in Nigeria.

BACKGROUND: We assessed clinical parameters in patients confirmed to have COVID-19 in relation to arterial hypoxaemia and survival. METHODOLOGY: This was a retrospective chart review of patients who were confirmed positive for SARS-CoV-2 virus by Real Time-Polymerase Chain Reaction (RT-PCR) testing. Data extracted from patients' case files included patient demographics, presenting symptoms, provisional diagnoses, and outcomes of hospitalisation. Descriptive variables were summarized; proportions were compared using Chi-square tests, and independent predictors of mortality were assessed using multivariate regression analysis. A p-value of < 0.05 was considered as statistically significant. RESULTS: There were a total of 61 patients with positive RT-PCR testing: mean age ± SD (minimum - maximum) was 53.0 ± 18.5 (5 months - 90) years. Persons aged 60 years and above were the largest group (n=24, 39.3%). More than half were male (n=35, 57.4%); about 43% had one morbidity; 41.0% had at least two co-morbidities. The mean (SD) arterial oxygen saturation (SpO2) was 86.9% ± 16.7. Patients who were clinically dyspnoeic at presentation, and who had co-morbidities were significantly more hypoxaemic (p = 0.026 and 0.04, respectively). Significantly more patients who had normal oxygen saturation at presentation survived (p = 0.006). None of these variables was an independent predictor of mortality, however. CONCLUSION: Arterial hypoxaemia was significantly associated with dyspnoea and underlying disease, and normal oxygen saturation at presentation was significantly associated with survival. Hospital managers and clinicians may thus prioritize routine pulse oximetry, supplemental oxygen therapy and management of co-morbidities in the COVID-19 fight.

An Analysis of COVID-19 Patients Receiving Care in a Tertiary Facility in Southern Nigeria.

BACKGROUND: Information pertaining to the clinical characteristics of COVID-19 in sub-Saharan Africa remains sparse. In Nigeria, it is limited to few isolated reports and case series confined to the early phase of the outbreak. The objective of this study is to describe the presenting characteristics, co-morbidities and outcomes of Nigerian patients managed over a 3-month period in a tertiary hospital. METHODS: This was a descriptive cross-sectional study involving the total population of patients with laboratory confirmed diagnosis of COVID-19 in the University of Benin Teaching Hospital, Edo State, Nigeria from March 31 to June 30, 2020. Data was collected using a review of patients' records. Analysis was by IBM SPSS version 25.0. The level of significance was set at p < 0.05. RESULTS: A total of 173 patients with mean age (SD) 50.7± 20.1 years were managed. One hundred and five (60.7%) were males and the commonest age group was 20-39 years (34.7%). The commonest presenting symptoms were fever, cough and malaise found in 103 (71.5%), 101 (70.1%) and 63 (43.8%) patients respectively. Twenty-five (14.5%) patients had severe disease; 60 (34.7%) had underlying medical conditions mostly hypertension and diabetes mellitus. Outcome analyses showed 117 (67.6%) discharges, 45 (26.0%) deaths, 10 (5.8%) discharges against medical advice, and 1 (0.6%) transfer to another facility. Male sex (p=0.044), increasing age (p<0.001), presence of symptoms (p=0.010), presence of co-morbidities (p=0.010) and non-healthcare worker status (p< 0.001) were significantly associated with mortality. CONCLUSION: The first epidemiological and clinical summary of COVID-19 cases in Edo state, Nigeria over a three-month period is presented showing globally recognized patterns of male predilection and higher mortality with increasing age and co-morbidity.

The prevalence of overweight and its risk factors among adolescents in an urban city in Edo State.

INTRODUCTION: The prevalence of overweight is rising even in countries with significant rates of undernutrition. This is exacerbated by westernization of lifestyles and the image of prosperity associated with overweight. Children are not spared and the health consequences may become apparent in the near future. This study assessed the prevalence of overweight among adolescents in an urban city in a developing country. METHODOLOGY: This cross-sectional study conducted from September to December 2005 involved 300 adolescents selected by cluster sampling in Benin-city, Nigeria. Overweight and risk of overweight were defined as Body mass index (BMI)-for-age > or = 95th percentile and BMI-for-age 85th to < 95th percentile respectively. RESULTS: Of the participants, 5.7% were overweight while 52.7% were at risk of overweight. Risk factors of overweight identified were consumption of snacks (64.3%), soft drinks (85.7%) and physical inactivity (69.7%). Being overweight was significantly associated with consumption of snacks, soft drinks, physical inactivity and positive family history of obesity, (p < 0.05). CONCLUSION: The high prevalence of risk factors for overweight suggests that the already high prevalence of overweight will increase in the near future. Preventive measures are required to forestall this increase.

Awareness of high blood pressure status, treatment and control in a rural community in Edo State.

A cross-sectional study was carried out in Udo, a rural community in Ovia South-west LGA of Edo State to assess the level of awareness of high blood pressure status, treatment and control. Cluster sampling method was used to select participants and data collection was by researcher administered questionnaire. Blood pressure measurement was by standardized method. A total of 590 respondents with mean age 30.7 +/- 14.6 years participated in the study. The prevalence of hypertension was 20.2% using the WHO/ISH criteria of SBP > or = 140 mmHg and/or DBP > or = 90 mmHg. Twenty two (18.5%) of the hypertensives were aware of their high blood pressure status. Awareness was higher in females, increased with age and decreased with higher educational status. Of those aware of their condition, 77.3% were on treatment and ofthese, 29.4% had adequate blood pressure control. This study has revealed a low level of awareness of high blood pressure status and control in this rural community. Therefore, there is urgent need for regular community-based hypertension screening programmes.
