Cardiovascular Risk Awareness, Exercise Practices and Metabolic Outcomes among Patients with Diabetes Mellitus in Northern Nigeria: A Cross-sectional, Multicentre Study.

BACKGROUND: Physical exercise helps to mitigate cardiovascular risks in people with diabetes mellitus (DM), but there are limited data in Nigeria. This study aimed to assess cardiovascular risk awareness, exercise practices and metabolic outcomes among Nigerians with diabetes. MATERIALS AND METHODS: We conducted a cross-sectional study at five tertiary hospitals using questionnaire interviews and clinical assessments. Participants' knowledge of cardiovascular risk factors and knowledge of exercise were assessed on 12- and 5-item scores, while exercise practices were classed as adequate if performed regularly on 3 or more days weekly for a total of 150 min or more based on the American Diabetes Association recommendations. Mean body mass index (BMI), blood pressure (BP), fasting blood glucose, serum haemoglobin A1C (HbA1c), lipid profile, urea, creatinine and uric acid were then compared among participant groups. RESULTS: We studied 426 participants with DM, 58.7% females. The mean age was 52.9 ± 13.1 years, with males significantly older than females (54.6 ± 12.2 vs. 51.8 ± 13.5 years; 95% confidence interval: 0.27-5.28, P = 0.03). The mean age at diabetes diagnosis was 44.8 ± 11.7 years, and the median duration of diabetes was 84 months. There was low knowledge of cardiovascular risk factors and low knowledge of exercise (mean scores of 2.94 and 2.31, respectively). Forty-three per cent of participants reported adequate exercise, which was significantly associated with younger age (P = 0.007), male gender (P = 0.001) and formal education (P = 0.021). Participants with adequate exercise had lower systolic BP and serum urea compared to those with inadequate exercise, but there were no significant differences in BMI, fasting glucose, HbA1c, serum lipids, creatinine or uric acid. CONCLUSION: Participants had low knowledge of cardiovascular risks and the appropriate exercise practices for diabetes patients. There is a need for better patient education on diabetes self-care and exercise at clinic visits.

FEV1, FVC, FEV1 /FVVC as predictors of rhinitis among saw mill workers in north central Nigeria.

Background: Rhinitis is one of the commonest occupational related respiratory disorders that is only restricted to the upper airway but can involve the lower respiratory tract with considerable airflow limitation, this study was conducted assess the ventilator function of persons exposed to saw dust with rhinitis symptoms. Methods: This is a cross sectional study carried out among 200 randomly selected saw mill workers and 200 healthy staff of Jos University Teaching Hospital staff in Jos metropolis from September to November 2008. Data on sociodemographic variables, symptoms of rhinitis, etc was obtained using a modified semi structured British medical research council questionnaire while respiratory function data was measured using a spirometry. Result: A total of 400 responds comprising of 200 saw mill workers and 200 controls participated in this study. Based on diagnostic criteria. 43% of the subjects fit into diagnosis of rhinitis, 33% had asthma symptoms and 24 % did not fit into any category compared to none of < 5% of the control group. The ventilatory function based on FEV1, FVC, FEV1/FVC ratio and PEFR showed a significant decline when matched with controls and predicted value, suggesting an airflow limitation among the rhinitis group. Conclusion: Rhinitis associated with wood dust exposure is not restricted to airway but involves the entire respiratory tract with airflow limitation as one of its consequences.

Trends in pediatric tuberculosis diagnosis utilizing xpert Mycobacterium tuberculosis/Rifampicin in a poor-resource, high-burden region: A retrospective, multicenter study.

Background: The burden of tuberculosis (TB) in Nigeria remains high, and diagnosis in children, a challenge. We aimed to document yield from Xpert Mycobacterium tuberculosis/rifampicin (MTB/RIF) as a mode of diagnosis for children and the variables associated with a positive result. Methods: This was a retrospective review of TB treatment cards of children aged 0-15 years managed from January 2017 to December 2021 across six public tertiary institutions in Nigeria. The data obtained were analyzed using the descriptive and inferential statistics. Statistical significance was set at P < 0.05. Results: Of 1489 children commenced on TB treatment, 1463 (97.9%) had sufficient data for analysis the median age of study participants was 60 months (interquartile range [IQR]: 24, 120), and 814 (55.6%) were males. Xpert MTB/RIF test was performed in 862 (59%) participants and MTB was detected in 171 (19.8%) participants, of which 6.4% (11/171) had RIF resistance reported. The use of Xpert MTB/RIF rose from 56.5% in 2017 to 64% in 2020 but fell to 60.9% in 2021. We found that older age (> 10 years), the presence of pulmonary TB (PTB), and a negative human immunodeficiency virus (HIV) status were associated with positive Xpert MTB/RIF tests (P = 0.002, 0.001, and 0.012, respectively). Conclusion: The utilization of Xpert MTB/RIF in children increased in the years before the COVID-19 pandemic. Factors associated with MTB detection by Xpert MTB/RIF include older age, the presence of PTB, and a negative HIV status. Clinical and radiological evaluation continues to play vital roles in the diagnosis of childhood TB in Nigeria.

Spinocerebellar ataxia type-7: Report of a family in Northwest Nigeria.

Spinocerebellar ataxia type-7 (SCA7) is a cytosine-adenine-guanine (CAG) repeat polyglutamine disorder characterized by progressive degeneration of the cerebellum, brainstem, spinal cord, and retina. Clinical features include progressive ataxia, visual loss, pyramidal weakness, sensory impairment, and dementia. Among the autosomal dominant cerebellar ataxias, SCA7 is relatively common in Scandinavia and South Africa but rare worldwide and is not previously reported in Nigeria. In this study, we describe a family in Katsina State, Northwest Nigeria, with nine individuals across three generations affected by the SCA7 phenotype. Analysis of DNA from proband and two affected relatives revealed 39 CAG repeat expansions in one allele of ataxin-7 in each.
