Causes of infant and under-five (under-5) morbidity and mortality among hospitalized patients in Southern Nigeria: A hospital based study.

Background: Rate and pattern of under-five mortality is a reflection of a society's healthcare system and quality of life. This study is aimed at reviewing the causes of infants and under-five morbidity and mortality in Calabar, Southern Nigeria. Methods: This study used retrospective descriptive cross-sectional design. We did a retrospective collation of data on under-five morbidity and mortality from 2012 to 2017 of under-five patients admitted or died while in admission in University of Calabar Teaching Hospital. The causes of morbidity and mortality were reported based on International Classification of Diseases 10 (ICD-10). The morbidity, mortality and fatality rates were computed. Results: A total of 11,416 under-five admissions and 391 deaths were recorded within the study period giving a fatality rate of 3.4%. Age 1-4 years category represented 50.5% of the admissions while infants (<1 year) constitute majority of the deaths (64.7%). There were 5652 infant admissions and 253 infant deaths giving fatality rate of 4.5% within the study period. Males constituted majority (55.8%) of under-five morbidity whereas females constituted majority (51.2%) of the deaths. Conditions originating from perinatal period; and infectious and parasitic diseases were the leading broad cause of under-five mortality. Specific disease analysis showed sepsis/septicemia; congenital infectious and parasitic diseases; slow fetal growth, malnutrition and short gestation as the chief causes of both infant and under-five mortality. Conclusion: The leading causes of under-five deaths in the studied population are amenable. Improved healthcare and antenatal will be of immense benefit.

Assessment of knowledge, perception, preventive practices and effects of COVID-19 among Nigerians: a cross-sectional study.

Introduction: the coronavirus disease 2019 (COVID-19) has become a disease of global public health concern. The current cumulative cases in Nigeria are high. The effective control of the pandemic is dependent on knowledge, attitude and willingness of people to adapt their life to the new reality. The purpose of this study is to determine the knowledge, perception, preventive practice, and effect of COVID-19 on the respondents. Methods: we conducted a cross sectional, online survey-based study (Google form) from May 25th, 2020 to June 25th, 2020. The survey questionnaire consisted of demographic characteristics, 13 items on knowledge, 6 items on preventive practices, 13 items on perception. Descriptive statistics, t-test, one-way ANOVA and bivariate logistic regression were carried out. Results: the correct overall knowledge was 98.03% with average score of 11.7 ± 1.0 (9-13). Knowledge scores were comparable in all demographics except marital status. Most of the participants practiced preventive procedures such as wearing face mask (95.1%), use of alcohol based hand sanitizer (78.9%), avoidance of worship centers (62.4%) and regular hand washing. There were several perceptions ranging from rumors to unfounded scientific claims. Gender, level of education, monthly income and Christian denomination were predictors of use of hand sanitizer while age, level of education, monthly income, Christian denomination and region were predictors of attendance of worship centers during lockdown. Conclusion: the results of this study suggest government should gain trust of citizens to translate knowledge to practice and full compliance of regulations.

Coping with COVID-19 pandemic in blood transfusion services in West Africa: the need to restrategize

ABSTRACT Introduction The West African region has been lagging in terms of the availability of, and accessibility to, safe blood. According to the 2016 World Health Organization (WHO) Global Status Report on Blood Safety and Availability, none of the West African countries met the WHO benchmark of 10 blood units per 1000 inhabitants. This study is aimed at discussing the blood transfusion status of West African countries in the pre-COVID-19 period and analyze the capacity to respond to the COVID-19 blood crisis, as well as to outline the panacea. Methods Secondary data were extracted from published reports, journal articles and web pages, reviewed and analyzed. Result All the West African countries have recorded confirmed COVID-19 cases and deaths. The confirmed cases have reached 55,697, with 1069 deaths and a fatality rate of 1.9%, as of June 17, 2020. The assessed countries lagged in most of the WHO benchmarks for effective blood transfusion services. Conclusion Blood transfusion services in the West African region lacked the basic benchmark practice and policy, are not coordinated and may find it hard to tackle the blood transfusion crisis created by the COVID-19 pandemic.

Evaluation of Blood Oxidant/Antioxidant Changes and Testicular Toxicity after Subacute Exposure to Cadmium in Albino Rats: Therapeutic Effect of Nigella sativa Seed Extracts.

AIM AND OBJECTIVE: Cells and tissues of the body are prone to oxidative damage as a result of an increased level of reactive oxygen species and nitrogen radical beyond the detoxifying ability of the endogenous antioxidant system. This study aimed to evaluate the ameliorative effect of methanolic extracts of Nigella sativa (MENS) against cadmium-induced blood oxidative stress and testicular toxicity in albino rats. MATERIALS AND METHODS: Twenty-five (25) male albino rats, weighing (200 ± 20g), were randomly grouped into five groups (A-E). Group B (Negative Control) received intraperitoneal administration of cadmium chloride (CdCl2, 5 mg/kg) only, group C received CdCl2 and low dose MENS (300 mg/kg, oral), group D received CdCl2 and high dose MENS (600 mg/kg, oral), group E (Positive control) received CdCl2 and Vitamin C (200 mg/kg, oral), for 14 days. No treatment was administered to group A (Normal control). The oxidative state of the blood was assessed by measuring the blood levels or activities of MDA, CAT, GSH and SOD; while testicular injury was assessed by measuring serum testosterone level using ELISA. The testes were harvested for histopathological examination. RESULTS: The results showed that cadmium induced a marked elevation in the level of MDA, and a decrease in SOD, CAT and GSH levels or activities (p<0.05 or p<0.01); but no significant alteration in the serum testosterone level was found (p>0.05); Histopathological studies on the testes showed that cadmium significantly induced testicular injury, which was however ameliorated by the seed extract of N. sativa. CONCLUSION: We conclude that N. sativa seed extract is potentially testiculoprotective and attenuates oxidative stress against harmful chemical toxins such as cadmium.

Correlative Study of Bone-related Biochemicals and Endocrine Changes in Perimenopausal Women in Enugu, Nigeria.

BACKGROUND AND OBJECTIVE: Perimenopause is a physiological occurrence in women, and is characterized by endocrine and biochemical changes. During perimenopause phase, many derangements or abnormal health conditions start developing as a result of hormonal changes. These derangements in health conditions and biochemical changes lead to higher incidence of metabolic syndrome (MetS) occurrence with or without bone involvement. There is a scarcity of information on MetS in Enugu, Southern Nigeria and there is no available data on the correlation of selected bone-related biochemicals with endocrine parameters and MetS in perimenopausal women from the region. MATERIAL AND METHODS: We consecutively sampled 200 apparently healthy women, and categorized them into 120 perimenopausal women (age (!) = 50years) and a second group of 80 women in premenopause (age (!) = 35years). Measurement of anthropometric indices like blood pressure, height, weight and waist circumference were taken. Fasting blood samples were collected for the estimation of endocrine parameters (estradiol (E2), follicle stimulating hormone (FSH), and luteinizing hormone (LH)) using enzyme linked immunosorbent assay (ELISA) technique. The lipid profile, fasting plasma glucose (FPG), uric acid, inorganic phosphate, calcium and alkaline phosphatase levels were determined using standard biochemical methods. The evaluation of MetS was carried out in the women using the three different criteria: World Health Organization (WHO), National Cholesterol Education Program- Adult Treatment Panel 111 (NCEP-ATP 111) and International Diabetes Federation (IDF). For statistical analysis, Student's t-test, Pearson correlation and Chi-square were used to compare categorical and continuous variables. RESULTS: Calcium was predominantly high in the three criteria (p<0.05). LH and FSH showed a positive correlation with FPG while E2 was negatively associated with FPG. Similarly, LH showed a positive association with inorganic phosphate while E2 was negatively associated with alkaline phosphatase (p<0.05). CONCLUSION: Perimenopausal women are at higher risk of developing osteoporosis than premenopausal women. This emphasizes the need for timely diagnosis of osteoporosis in perimenopausal women.

COVID-19 in WHO African Region: Account and Correlation of Epidemiological Indices with Some Selected Health-related Metrics.

Background: The coronavirus disease 2019 (COVID-19) is a highly contagious and pathogenic viral disease caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). Since it was first reported in Wuhan, China, it has spread across the continents. The study is aimed at describing epidemiological indices of COVID-19 as reported by the World Health Organization and to examine correlations with some country specific measures of general health status. Methods: Data from the WHO African region were extracted from World Health Organization, Global Health Security Index, Worldometer and World Bank databases, as at September 8, 2020. Other epidemiological indices were computed for the various countries. Epidemiological indices of COVID-19 were correlated with some selected health related metrics: Global Health Security index (GHSI) and current health expenditure (CHE). Pearson correlation was used to access the relationship between the health-related metrics and epidemiological indices. Results: Forty-seven (47) countries belonging to the WHO African region were evaluated. A total of 1,086,499 confirmed cases and 23,213 deaths were recorded giving a fatality rate of 2.1%. South Africa recorded the highest cumulative confirmed cases as well as deaths (Cases: 639,362; Deaths: 15,004) while Seychelles (Cases:135) and Eritrea/Seychelles (Deaths:0) had the least cumulative cases and deaths (135;0 and 330;0), respectively. South Africa recorded the highest attack rate (1127.67/100,000) while Republic of Tanzania recorded the least attack rate (0.78/100,000). The highest case fatality rate/ratio was observed in Chad (7.60%) while the least value was observed in Seychelles (0.0%). France was the most common country involved in travel history of index cases. Sporadic transmission was recorded in 3 countries, 9 countries had cluster of cases while the rest had community transmission. The first WHO African region country to record COVID-19 case was Algeria, while Comoros was the last. Significant positive correlation was found between COVID-19 case number/deaths and Global Health Security Index. Conclusion: The WHO African region has had its own share of the pandemic with all the countries being affected. The trio of cluster cases, sporadic and community transmission were recorded with majority being community transmission.

Combination of aqueous extracts of Curcuma longa (turmeric) and some calcium channel blockers synergistically improves CCl4-induced nephrotoxicity in albino rats.

In the present study, special attention was drawn to CCl4-induced acute kidney injury (AKI) and how the nephrotoxicity could be treated or prevented by administration of aqueous extracts of Curcuma longa (AECL) alone or in combination with some calcium channel blockers. Thirty (30) male albino wister rats were grouped according to their weight into 6 groups (A-F) of 5 rats per group. Rats in groups A-D received CCl4 (0.4ml/kg b.wt, i.p) for 3 days. Group B received AECL (200mg/kg, oral), Group C received AECL and nifedipine (1mg/100g of rat, i.p), Group D received AECL and amlodipine (1mg/100g of rat, i.p), and group E received AECL alone with no CCl4 challenge for 3 days. No treatment was administered to group F (Normal control). Serum renal biochemical parameters; MDA level and SOD activity in the kidney homogenates were measured. CCl4 administration to the rats resulted to acute kidney injury with significantly increased Urea, Creatinine, K+ and MDA levels and decreased SOD activity (p<0.05, p<0.01 or p<0.001). The 3 days daily administration of AECL alone or plus nifedipine or amlodipine resulted in the attenuation of the CCl4-induced kidney injury with significantly decreased Urea, Creatinine, K+ and MDA levels and increased SOD activity (p<0.05. p<0.01). Histopathological results showed a concomitant association with the biochemical findings. This study shows that the combination of the extract and some calcium channel blockers is synergistically nephroprotective and can be used to prevent acute renal injury.

Prevalence and associated risk factors of peripheral artery disease in virologically suppressed HIV-infected individuals on antiretroviral therapy in Kwara state, Nigeria: a cross sectional study.

BACKGROUND: The association between HIV and cardiovascular disease (CVD) has been reported in several studies. However, there is paucity of information on the prevalence of subclinical disease as well as its associated risk factors in sub-Saharan African population. The aim of this study was to determine the prevalence and associated risk factors of peripheral artery disease (PAD) among virologically suppressed HIV-infected participants in Kwara State, Nigeria. METHODS: This study was conducted between July 2018 and December 2018. A total of 150 HIV-infected participants aged between 20 and 55 years and 50 HIV non-infected age-matched controls were randomly recruited in the study. Sociodemographic, anthropometric and clinical data were collected using a well-structured questionnaire. Ankle brachial index (ABI) was measured, PAD was defined as ABI of < 0.9. Cryopreserved serum was used to evaluate lipid profile parameters. Student's t-test and Chi-square were used to compare continuous and categorical variables. Associations of CVD risk factors and clinical data, and lipid profile with low ABI were assessed using logistic regression analysis. RESULTS: The study participants had a mean age of 43.73 ± 8.74, majority were females (72.7%) with a mean duration on ART of 7.73 ± 3.52 years. Hypertension was present in 15.9%, diabetes 4%, family history of CVD 8.6% and metabolic syndrome 17.3% in the study group. The study participants recorded significantly lower mean values for ABI, HDL-C and significantly higher mean values of TG (P < 0.05) compared to the control group. The prevalence of low ABI (14.6%) was higher in the study group compared to the control group (2%). A significantly negative correlation between ABI and duration on ART (r = - 0.163, P = 0.041) and a positive correlation between viral load and TG were observed in the study group. TC (OR 1.784, P = 0.011), LDL-C (OR 1.824, P = 0.010) and CD4 cell count < 200 cells/mm3 (OR 2.635, P = 0.364) were associated with low ABI in the participants. CONCLUSION: Viral suppression with combined antiretroviral therapy and long term treatment is associated with dyslipidaemia, with increased risk of PAD. Prevalence of PAD in virologically-suppressed individuals does not differ from the controls in the population studied.
