Hyperhomocysteinemia and its relations to conventional risk factors for cardiovascular diseases in adult Nigerians: the REMAH study.

BACKGROUND: Evidence linking homocysteine (Hcy) with cardiovascular diseases (CVD) or its risk factors are limited in a sub-Saharan black population. OBJECTIVE: We set out to evaluate the association between Hcy and hypertension and other CVD risk factors in a population of adult Nigerians. METHODS: Data of 156 adults aged 18-70 years was accessed from the North Central study site of the REmoving the MAsk on Hypertension (REMAH) study. Homocysteine, blood glucose and lipid profile in whole blood/serum were measured using standard laboratory methods. Hypertension was diagnosed if average of 5 consecutive blood pressure (BP) measurements obtained using a mercury sphygmomanometer was equal to or higher than 140 systolic and/or 90 mmHg diastolic or the individual is on antihypertensive medication. Hyperhomocysteinemia (HHcy) was defined as Hcy > 10 µmol/L. RESULTS: Of the 156 participants, 72 (43.5%) were hypertensive, of whom 18 had HHcy. Subjects with HHcy were significantly (p < 0.05) older (41.5 vs. 40.6yrs), had lower HDL-cholesterol (0.6 vs. 0.8 mmol/L) and higher systolic (145.5 vs. 126.0 mmHg) and diastolic BP (92.9 vs. 79.6 mmHg), compared to those without HHcy. Intake of alcohol and a 1 yr increase in age were respectively and significantly (p < 0.05) associated with a 1.54 and 0.10 µmol/L increase in Hcy. In a multivariable model adjusted for age, sex and body mass index, a 1 µmol/L increase in Hcy, was associated with a 1.69 mmHg and 1.34 mmHg increase in systolic and diastolic pressure (p < 0.0001) respectively; and a 0.01 mmol/L decrease in HDL-cholesterol (p < 0.05). CONCLUSION: HHcy occurs among hypertensive Nigerians and it is independently associated with age, HDL-cholesterol, systolic and diastolic BP.

The post-Ebola virus disease scourge in Nigeria: Individual levels of preparedness among physicians in the Federal Capital Territory Abuja.

BACKGROUND: Ebola virus disease (EVD) is a viral hemorrhagic illness with great propensity for spread across international borders. The latest outbreak in the West African region, which involved Nigeria, was the worst among previously documented 25 outbreaks since discovery in 1976. The Nigerian response toward attaining Ebola free status was phenomenal and a case study for most nations. However, the persistence of EVD in West Africa is still a risk to recurrence, hence, the need to assess the level of consciousness of Nigerian physicians towards this. METHODOLOGY: A cross-sectional study utilizing the instrument of a pretested semi-structured questionnaire was conducted among physicians practicing within the federal capital city of Nigeria. General knowledge, treatment, prevention, and reporting of EVD were assessed and appropriate statistical analyses done using SPSS 20. RESULTS: Of the 101 respondents, 45% and 87% showed excellent level (>80% score) of "general knowledge" and "reporting" on EVD, respectively. However, only 51% respondents had good (60-80%) knowledge on EVD treatment. Three percent correctly identified the "EVD helpline" phone-numbers for reporting suspected cases. Furthermore, 43.6% admitted the availability of personal protective equipment (PPE) in their hospitals while 35.6% had witnessed a demonstration of the use. The distribution of the PPEs appeared skewed - 74.4% (teaching-hospitals), 16% (private-hospitals), and the primary health care centers (9.6%). CONCLUSION: A majority of the physicians showed good level of preparedness as it relates to general knowledge on EVD, knowledge on good clinical practice, use of protocols and standard precautions and PPE. The identification of deficits in knowledge on treatment of EVD and flow path for the notification of suspected cases requires urgent redress given the risk of re-occurrence in the country.
