Health Risks of Obesity
Obesity is becoming of interest as a non-communicable disease. There is however a dearth of information on obesity in this environment, as literature in developing countries is limited. Review of health risks of obesity is useful in order to increase the pool of available information in Nigeria and to draw attention to obesity and its attendant health risks.Keywords: Health, risks, obesity
Haematological and hepatic indices of cockerels fed treated dietary Blighia sapida seeds
Ninety-six day old Lairier cockerel chicks were used in an experiment to evaluate the after effects of detoxifying (soaking, boiling, addition of riboflavin and glycine to antagonize hypoglycins) dietary Blighia sapida (ackee apple) seed meal, BSSM. Blood chemistry, haematology, liver morphology indices which dietary BSSM influenced and reflected in the performance characteristics of the cockerels investigated in a single-factor experimental design experiment were assessed. Results showed that the residual phytotoxins of BSSM, hypoglycins A & B with their metabolite MCPA at 17.50% inclusion of the processed BSSM in diets elicited reduction in glucose, protein, albumin, globulin while elevating blood cholesterol, creatinine, urea,total and conjugated bilirubin relative to the reference diet (p <0.05).Dietary BSSM similarly increased the transaminase activities of AST/SGOT, ALT/SGPT including ACP (p < 0.05). BSSM based diets also caused significant reduction in PCV, RBC, WBC, Hb as well as MCV, MCH and MCHC similar to the results obtained on WBC differential counts of neutrophils and lymphocytes in comparison with the conventional diet (p < 0.05). Histopathological examinations on the liver samples revealed that the control diet presented livers that were normal in tissue morphology without inflammation or haemorrhage while the photomicrographs of the liver samples of cockerels fed treated dietary BSSM at 17.50% inclusion showed morphological patterns indicating severe distortion suggesting evidence of haemorrhage and inflammation with numerous blood cells occupying the available hepatic sinuses. The poor results recorded on the biochemical, haematological and morphological parameters were reflected in performance characteristics as reduced feed intake, weight gain, growth rate, feed efficiency and high mortality were obtained on diets containing BSSM compared with the orthodox diet (p < 0.05). Findings of this experiment indicated that for optimum results, processed BSSM be included in diets below the 17.50% level considered high for the birds in this study.KEYWORDS: Cockerels, BSSM, treatments, blood chemistry,haematological and performance indice
Obesity: An emerging disease
Obesity is rapidly becoming an emerging disease in developing countries due to the increasing westernization of societies and change in the lifestyle. The etiology of obesity is said to be multifactorial, with a combination of genetic and environmental factors. Literature has been extensively reviewed to provide a broad overview of obesity. Data for this review were obtained from original articles, review articles and textbooks. Internet search engines were also employed. The years searched were from 1993 to 2008. Obesity, classified in terms of the body mass index and the waist–hip ratio, has several associated co-morbidities such as diabetes mellitus, hypertension, degenerative osteoarthritis and infertility. In Nigeria, there is limited information on obesity. A literature review on obesity is necessary to improve the knowledge about obesity in developing countries, its prevention and its management
Patient characteristics associated with COVID-19 positivity and fatality in Nigeria: retrospective cohort study
Objective: Despite the increasing disease burden, there is
a dearth of context-specific evidence on the risk factors for
COVID-19 positivity and subsequent death in Nigeria. Thus,
the study objective was to identify context-specific factors
associated with testing positive for COVID-19 and fatality
in Nigeria.
Design Retrospective cohort study.
Setting: COVID-19 surveillance and laboratory centres in
36 states and the Federal Capital Territory reporting data to
the Nigeria Centre for Disease Control.
Participants: Individuals who were investigated for SARSCoV-2 using real-time PCR testing during the study period
27 February–8 June 2020.
Methods: COVID-19 positivity and subsequent mortality.
Multivariable logistic regression analyses were performed
to identify factors independently associated with both
outcome variables, and findings are presented as adjusted
ORs (aORs) and 95% CIs.
Results: A total of 36 496 patients were tested for
COVID-19, with 10 517 confirmed cases. Of 3215
confirmed cases with available clinical outcomes, 295
died. Factors independently associated with COVID-19
positivity were older age (p value for trend<0.0001), male
sex (aOR 1.11, 95%CI 1.04 to 1.18) and the following
presenting symptoms: cough (aOR 1.23, 95% CI 1.13 to
1.32), fever (aOR 1.45, 95% CI 1.45 to 1.71), loss of smell
(aOR 7.78, 95% CI 5.19 to 11.66) and loss of taste (aOR
2.50, 95% CI 1.60 to 3.90). An increased risk of mortality
following COVID-19 was observed in those aged ≥51
years, patients in farming occupation (aOR 7.56, 95% CI
1.70 to 33.53) and those presenting with cough (aOR 2.06,
95% CI 1.41 to 3.01), breathing difficulties (aOR 5.68, 95%
CI 3.77 to 8.58) and vomiting (aOR 2.54, 95% CI 1.33 to
4.84).
Conclusion: The significant risk factors associated with
COVID-19 positivity and subsequent mortality in the
Nigerian population are similar to those reported in studies
from other countries and should guide clinical decisions for
COVID-19 testing and specialist care referrals

Maternal and neonatal outcomes after caesarean delivery in the African Surgical Outcomes Study: a 7-day prospective observational cohort study.
BACKGROUND: Maternal and neonatal mortality is high in Africa, but few large, prospective studies have been done to investigate the risk factors associated with these poor maternal and neonatal outcomes. METHODS: A 7-day, international, prospective, observational cohort study was done in patients having caesarean delivery in 183 hospitals across 22 countries in Africa. The inclusion criteria were all consecutive patients (aged ≥18 years) admitted to participating centres having elective and non-elective caesarean delivery during the 7-day study cohort period. To ensure a representative sample, each hospital had to provide data for 90% of the eligible patients during the recruitment week. The primary outcome was in-hospital maternal mortality and complications, which were assessed by local investigators. The study was registered on the South African National Health Research Database, number KZ_2015RP7_22, and on ClinicalTrials.gov, number NCT03044899. FINDINGS: Between February, 2016, and May, 2016, 3792 patients were recruited from hospitals across Africa. 3685 were included in the postoperative complications analysis (107 missing data) and 3684 were included in the maternal mortality analysis (108 missing data). These hospitals had a combined number of specialist surgeons, obstetricians, and anaesthetists totalling 0·7 per 100 000 population (IQR 0·2-2·0). Maternal mortality was 20 (0·5%) of 3684 patients (95% CI 0·3-0·8). Complications occurred in 633 (17·4%) of 3636 mothers (16·2-18·6), which were predominantly severe intraoperative and postoperative bleeding (136 [3·8%] of 3612 mothers). Maternal mortality was independently associated with a preoperative presentation of placenta praevia, placental abruption, ruptured uterus, antepartum haemorrhage (odds ratio 4·47 [95% CI 1·46-13·65]), and perioperative severe obstetric haemorrhage (5·87 [1·99-17·34]) or anaesthesia complications (11·47 (1·20-109·20]). Neonatal mortality was 153 (4·4%) of 3506 infants (95% CI 3·7-5·0). INTERPRETATION: Maternal mortality after caesarean delivery in Africa is 50 times higher than that of high-income countries and is driven by peripartum haemorrhage and anaesthesia complications. Neonatal mortality is double the global average. Early identification and appropriate management of mothers at risk of peripartum haemorrhage might improve maternal and neonatal outcomes in Africa.
