Advancing disease genomics beyond COVID-19 and reducing health disparities: what does the future hold for Africa?

The COVID-19 pandemic has ushered in high-throughput sequencing technology as an essential public health tool. Scaling up and operationalizing genomics in Africa is crucial as enhanced capacity for genome sequencing could address key health problems relevant to African populations. High-quality genomics research can be leveraged to improve diagnosis, understand the aetiology of unexplained illnesses, improve surveillance of infectious diseases and inform efficient control and therapeutic methods of known, rare and emerging infectious diseases. Achieving these within Africa requires strong commitment from stakeholders. A roadmap is needed to guide training of scientists, infrastructural development, research funding, international collaboration as well as promote public-private partnerships. Although the COVID-19 pandemic has significantly boosted genomics capacity in Africa, the continent still lags other regions. Here, we highlighted key initiatives in genomics research and efforts to address health challenges facing the diverse and fast-growing populations on the continent. We explore the scalability of genomic tools and techniques to tackle a broader range of infectious diseases in Africa, a continent that desperately requires a boost from genomic science.

Recent advances and challenges in the early diagnosis and management of invasive fungal infections in Africa.

Invasive fungal infections are a serious concern globally, especially in African settings which are typified by poorly funded and fragile healthcare systems. Low performance diagnostics, limited therapeutics and poor societal awareness of invasive fungal infections are some of the perennial challenges which have contributed to the unacceptably high death rates from these serious infections. However, recent advances have been recorded in fungal diagnostics and therapeutics development. Research into the development of vaccines to prevent fungal disease is beginning to yield promising results. Here we highlight key successes recorded and gaps in this journey and argue that national governments and relevant stakeholders need to do more to prioritise invasive fungal infections. Pragmatic and context-specific measures are proposed to mitigate the peculiar challenges Africa faces in tackling invasive fungal infections.

mHealth guideline training for non-communicable diseases in primary care facilities in Nigeria: a mixed methods pilot study.

OBJECTIVE: To pilot the use of a scalable innovative mobile health (mHealth) non-communicable diseases (NCDs) training application for nurses at the primary care level. DESIGN: Mixed methods pilot of mHealth training on NCD care for nurses at primary healthcare (PHC) facilities. We provide a descriptive analysis of mHealth training test scores, with trend analysis of blood pressure (BP) control using paired t-test for quantitative data and thematic analysis for qualitative data. SETTING: PHC facilities in rural and urban communities in Cross River State, south eastern Nigeria. NCDs were not part of routine training previously. As in most low-and-middle-income settings, funding for scale-up using conventional classroom in-service training for NCDs is not available in Nigeria, and onsite supervision poses challenges. PARTICIPANTS: Twenty-four health workers in 19 PHC facilities. INTERVENTION: A self-paced mHealth training module on an NCD desk guide was adapted to be applicable within the Nigerian context in collaboration with the Federal Ministry of Health. The training which focused on hypertension, diabetes and sickle cell disease was delivered via Android tablet devices, supplemented by quarterly onsite supervision and group support via WhatsApp. The training was evaluated with pre/post-course tests, structured observations and focus group discussions. This was an implementation pilot assessing the feasibility and potential effectiveness of mHealth training on NCD in primary care delivery. RESULTS: Nurses who received mHealth training recorded a statistically significant difference (p<0.001) in average pretest and post-test training scores of 65.2 (±12.2) and 86.5 (±7.9), respectively. Recordings on treatment cards indicated appropriate diagnosis and follow-up of patients with hypertension with significant improvements in systolic BP (t=5.09, p<0.001) and diastolic BP (t=5.07, p<0.001). The mHealth nurse training and WhatsApp support groups were perceived as valuable experiences and obviated the need for face-to-face training. Increased workload, non-availability of medications, facility-level conflicts and poor task shifting were identified challenges. CONCLUSIONS: This initiative provides evidence of the feasibility of implementing an NCD care package supported by mHealth training for health workers in PHCs and the strong possibility of successful scale-up nationally.

Evaluation of knowledge and awareness of invasive fungal infections amongst resident doctors in Nigeria.

INTRODUCTION: it has been estimated that about 11.8% of the Nigerians suffer serious fungal infections annually. A high index of suspicion with early diagnosis and institution of appropriate therapy significantly impacts on the morbidity and mortality of invasive fungal infections (IFIs). METHODS: we conducted a cross-sectional multicentre survey across 7 tertiary hospitals in 5 geopolitical zones of Nigeria between June 2013 and March 2015. Knowledge, awareness and practice of Nigerian resident doctors about the diagnosis and management of invasive fungal infections were evaluated using a semi-structured, self-administered questionnaire. Assessment was categorized as poor, fair and good. RESULTS: 834(79.7%) of the 1046 participants had some knowledge of IFIs, 338(32.3%) from undergraduate medical training and 191(18.3%) during post-graduate (specialty) residency training. Number of years spent in clinical practice was positively related to knowledge of management of IFIs, which was statistically significant (p < 0.001). Only 2 (0.002%) out of the 1046 respondents had a good level of awareness of IFIs. Only 4(0.4%) of respondents had seen > 10 cases of IFIs; while 10(1%) had seen between 5-10 cases, 180(17.2%) less than 5 cases and the rest had never seen or managed any cases of IFIs. There were statistically significant differences in knowledge about IFIs among the various cadres of doctors (p < 0.001) as level of knowledge increased with rank/seniority. CONCLUSION: knowledge gaps exist that could militate against optimal management of IFIs in Nigeria. Targeted continuing medical education (CME) programmes and a revision of the postgraduate medical education curriculum is recommended.

Haemoptysis in a female with diabetes mellitus: a unique presentation of chronic pulmonary aspergillosis, pulmonary tuberculosis, and Klebsiella peumoniae co-infection.

While chronic pulmonary aspergillosis (CPA), pulmonary tuberculosis (PTB), and Klebsiella pneumoniae pneumonia co-infection is rare, we present a 50-year-old woman with uncontrolled diabetes who presented with these three diseases. There is considerable overlap in symptoms of PTB and CPA. Treatment with antifungals, anti-tuberculosis therapy, and antibiotics is beneficial.

Fahr's disease: a rare neurological presentation in a tropical setting.

While rare, Fahr's disease should be considered as a differential diagnosis for seizures, movement disorders, or cognitive impairment in tropical settings. Classically, bilateral calcification of the basal ganglia is seen on CT. Endemic infections, metabolic, and toxic causes should be excluded. Treatment using Levodopa is often beneficial.

Coronary artery disease and the profile of cardiovascular risk factors in South South Nigeria: a clinical and autopsy study.

Introduction. Death from coronary artery disease (CAD) has been until recently considered rare in Nigeria. We present a report of a study of CAD with its predisposing cardiovascular (CVD) risk factors in South South Nigeria. Methods. We examined the autopsy reports of 747 coroner cases and 41 consecutive clinically diagnosed cases of ischemic heart disease seen in South South Nigeria. Results. CAD was diagnosed in 13 (1.6%) of 747 autopsies. They were predominantly males, urban residents, and of high social class with combination of CVD risk factors of hypertension, alcohol use, diabetes mellitus, cigarette smoking, poor physical activities, and obesity. The mean serum cholesterol of the clinical subjects was 4.7 ± 1.57 mmol/L and 5.07 ± 1.94 mmol/L for angina and myocardial infarction, respectively, which was higher than the mean total cholesterol for locality of 3.1 mmol/L. Conclusion. CAD and its risk factors are contributing to mortality and morbidity in South South Nigeria. These risk factors include hypertension, alcohol use, diabetes mellitus, cigarette smoking, poor physical activity, and obesity. Nigerians in this locality with CAD have raised serum lipids.
