May Measurement Month 2017: screening for hypertension in Nigeria-Sub-Saharan Africa.

ABSTRACT: Hypertension and its complications are now responsible for about a quarter of emergency medical admissions in urban hospitals in Nigeria. It is the commonest risk factor for stroke, heart failure, chronic kidney disease, and dementia. Furthermore, high blood pressure is the commonest cause of sudden unexpected natural death in the country. Regrettably, the rate of awareness, treatment, and control is abysmally low in the country and in many parts of the world. May Measurement Month (MMM) is a global initiative of the International Society of Hypertension aimed at raising awareness of high blood pressure (BP) and to act as a temporary solution to the lack of screening programs worldwide. An opportunistic cross-sectional survey of volunteers aged ?18?years was carried out in May 2017. Blood pressure measurement, the definition of hypertension and statistical analysis followed the standard MMM protocol. A total of 19 904 individuals with a mean age of 40.9?years, were screened during MMM17. After multiple imputation, 6709 (36.2%) had hypertension. Of individuals not receiving anti-hypertensive medication, 4140 (25.9%) were found to have hypertension. Of individuals receiving anti-hypertensive medication, 1449 (58.8%) had uncontrolled BP. MMM17 was one of the largest BP screening campaigns undertaken in Nigeria. A significant number of the participants were identified with hypertension (but not on any treatment) and uncontrolled BP despite being treated. These results suggest that opportunistic screening can identify significant numbers with raised BP.

Project description:Sub-Saharan Africa represents 69% of the total number of individuals living with HIV infection worldwide and 72% of AIDS deaths globally. Pulmonary infection is a common and frequently fatal complication, though little is known regarding the lower airway microbiome composition of this population. Our objectives were to characterize the lower airway microbiome of Ugandan HIV-infected patients with pneumonia, to determine relationships with demographic, clinical, immunological, and microbiological variables and to compare the composition and predicted metagenome of these communities to a comparable cohort of patients in the US (San Francisco). Bronchoalveolar lavage samples from a cohort of 60 Ugandan HIV-infected patients with acute pneumonia were collected. Amplified 16S ribosomal RNA was profiled and aforementioned relationships examined. Ugandan airway microbiome composition and predicted metagenomic function were compared to US HIV-infected pneumonia patients. Among the most common bacterial pulmonary pathogens, Pseudomonas aeruginosa was most prevalent in the Ugandan cohort. Patients with a richer and more diverse airway microbiome exhibited lower bacterial burden, enrichment of members of the Lachnospiraceae and sulfur-reducing bacteria and reduced expression of TNF-alpha and matrix metalloproteinase-9. Compared to San Franciscan patients, Ugandan airway microbiome were significantly richer, and compositionally distinct with predicted metagenomes that encoded a multitude of distinct pathogenic pathways e.g secretion systems. Ugandan pneumonia-associated airway microbiome is compositionally and functionally distinct from those detected in comparable patients in developed countries, a feature which may contribute to adverse outcomes in this population. Please note that the data from the comparable cohort of patients in the USUS data was published as supplemental material of PMID: 22760045 but not submitted to GEO The 'patient_info.txt' contains 12 clinical, 7 immunological and 3 microbiological variables for each patient.
