A Comprehensive 16-Year Analysis of National Center for Health Statistics Data on the Top Three Causes of Death Before Age 75 by Sex, Race, and Hispanic Origin.

OBJECTIVE:  This study aimed to conduct a comprehensive 16-year analysis of years of potential life lost (YPLL) due to leading causes of death in the United States, focusing on disparities by sex, race/ethnicity, and specific causes of death using the National Center for Health Statistics (NCHS) data. METHODS:  Data from the NCHS spanning 2000-2016 were included. Age-adjusted YPLL rates per 100,000 population were analyzed, stratified by sex, race/ethnicity, and leading causes of death, including malignant neoplasms, heart disease, and cerebrovascular diseases. RESULTS:  Over 16 years, the total YPLL rate was 7,036.2 per 100,000 population. Males had a higher YPLL rate (8,852.5 per 100,000) than females (5,259.9 per 100,000). Among racial/ethnic groups, Black/African Americans had the highest YPLL rate (10,896.8 per 100,000), followed by American Indian/Alaska Natives (7,310.0 per 100,000), Hispanics/Latinos (5,256.8 per 100,000), and Asians/Pacific Islanders (3,279.7 per 100,000). Leading causes included malignant neoplasms (1,451.6 per 100,000), heart diseases (1,055.4 per 100,000), and cerebrovascular diseases (182.3 per 100,000). CONCLUSION: This analysis spanning 16 years highlights notable disparities in YPLL rates among different demographic groups. These differences are evident in the YPLL rates for males, which are higher than those for females. The YPLL rate is most pronounced among Black/African Americans, followed by American Indian/Alaska Natives, Hispanics/Latinos, and Asians/Pacific Islanders. The primary contributors to YPLL are malignant neoplasms, heart diseases, and cerebrovascular diseases. These findings emphasize the importance of addressing these disparities to enhance public health outcomes and mitigate the premature loss of life. Despite progress, disparities persist, highlighting the need for targeted interventions and further research.

The role of community-based approaches in achieving universal health coverage: addressing the Nigerian narrative.

Universal health coverage (UHC) is aimed at ensuring that individuals and communities have affordable access to essential health care services without facing financial hardship. Achieving UHC and the third sustainable development goal of the United Nations requires that health systems transition from a vertical, top-down, curative approach toward one that puts people at the core of health care services, such as community-centered health interventions. Nigeria operates a decentralized health care system with the least focus on primary health care, making access to quality, and affordable health care for several citizens a challenge as the major percentage of the Nigerian population relies on primary health care services. The limited number of health care workers, the poor economic state, the inadequate health financing structures and high illiteracy rates have led to challenges such as low health service availability, hesitancy to utilize health interventions, high out-of-pocket expenditure rates, and health misinformation. These can be effectively tackled at the community level by revamping primary health care services, adequate and sustainable health financing, establishing Ward Development Committees, and the involvement of community stakeholders in health policy implementation. Employing such community-based approaches will ensure continuous progress of the Nigerian health care system toward UHC.

Changes in the haematological parameters of HIV-1 infected children at 6 and 12 months of antiretroviral therapy in a large clinic cohort, North-Central Nigeria.

BACKGROUND: Prior to commencing antiretroviral therapy (ART), haematological abnormalities are a common occurrence in individuals diagnosed with human immunodeficiency virus (HIV). In the course of receiving ART, these abnormalities usually improve. We determined the prevalence of haematological abnormalities in children diagnosed with HIV-1 and the changes in haematological parameters that occur after 6 and 12 months of being on ART. METHODS: A cross-sectional study of HIV-1 infected children aged 2 months to 15 years, between July 2005 and March 2013, at the paediatric HIV clinic of the Jos University Teaching Hospital, Jos. Median values of repeated measures were compared using the Wilcoxon signed-rank sum test. RESULTS: The prevalence of anaemia, thrombocytopenia and leukopenia among the 941 children studied, prior to ART was 6.4%, 7.0% and 8.6%. Median (IQR) haemoglobin (Hb) levels increased from 10 g/dL (9-11 g/dL) at baseline to 11 g/dL (10-12 g/dL) and 11 g/dL (10-12 g/dL) at 6 and 12 months of ART (P<0.001 and P<0.001), respectively, a 10% increase in both cases. Also, platelet count increased from a median of 327×103/µL (243-426×103/µL) at baseline to 333×103/µL (266-408×103/µL) at 6 months and 339×103/µL (267-420×103/µL) at 12 months, representing a 1.8% and 3.7% increase, respectively. The median total white blood cell count decreased from 7.4×103/µL (5.3-9.9×103/µL) at baseline to 5.9×103/µL (4.6-8.0×103/µL) and 5.8×103/µL (4.5-7.5×103/µL) at 6 and 12 months of ART (P<0.001 and P<0.001), a 20.3% and 21.6% decrease, respectively. CONCLUSION: During the 12 months of ART, children in our cohort had significant improvements in haematological parameters such as haemoglobin levels and platelet counts, which would suggest an early positive response to ART.

Long-Term Outcomes on Antiretroviral Therapy in a Large Scale-Up Program in Nigeria.

BACKGROUND: While there has been a rapid global scale-up of antiretroviral therapy programs over the past decade, there are limited data on long-term outcomes from large cohorts in resource-constrained settings. Our objective in this evaluation was to measure multiple outcomes during first-line antiretroviral therapy in a large treatment program in Nigeria. METHODS: We conducted a retrospective multi-site program evaluation of adult patients (age ≥15 years) initiating antiretroviral therapy between June 2004 and February 2012 in Nigeria. The baseline characteristics of patients were described and longitudinal analyses using primary endpoints of immunologic recovery, virologic rebound, treatment failure and long-term adherence patterns were conducted. RESULTS: Of 70,002 patients, 65.2% were female and median age was 35 (IQR: 29-41) years; 54.7% were started on a zidovudine-containing and 40% on a tenofovir-containing first-line regimen. Median CD4+ cell counts for the cohort started at 149 cells/mm3 (IQR: 78-220) and increased over duration of ART. Of the 70,002 patients, 1.8% were reported as having died, 30.1% were lost to follow-up, and 0.1% withdrew from treatment. Overall, of those patients retained and with viral load data, 85.4% achieved viral suppression, with 69.3% achieving suppression by month 6. Of 30,792 patients evaluated for virologic failure, 24.4% met criteria for failure and of 45,130 evaluated for immunologic failure, 34.0% met criteria for immunologic failure, with immunologic criteria poorly predicting virologic failure. In adjusted analyses, older age, ART regimen, lower CD4+ cell count, higher viral load, and inadequate adherence were all predictors of virologic failure. Predictors of immunologic failure differed slightly, with age no longer predictive, but female sex as protective; additionally, higher baseline CD4+ cell count was also predictive of failure. Evaluation of long-term adherence patterns revealed that the majority of patients retained through 84 months maintained ≥95% adherence. CONCLUSION: While improved access to HIV care and treatment remains a challenge in Nigeria, our study shows that a high quality of care was achieved as evidenced by strong long-term clinical, immunologic and virologic outcomes.

Prevalence of and risk factors for pulmonary tuberculosis among newly diagnosed HIV-1 infected Nigerian children.

INTRODUCTION: Studies on the prevalence of and risk factors for tuberculosis (TB) among newly diagnosed human immunodeficiency virus (HIV)-infected children in sub-Saharan Africa are scarce and in Nigeria there is paucity of reported data. We determined the prevalence of and risk factors for pulmonary TB (PTB) in newly diagnosed (treatment-naïve) HIV-1 infected children at the pediatric HIV clinic of the Jos University Teaching Hospital (JUTH) in Nigeria. METHODS: We performed a retrospective analysis of 876 children, aged 2 months - 13 years, diagnosed with HIV-1 infection between July 2005 and December 2012, of which 286 were diagnosed with PTB at presentation after TB screening. The study site was the AIDS Prevention Initiative in Nigeria (APIN)-supported Pediatric HIV clinic at JUTH, Jos. A multivariate forward logistic regression modelling was used to identify risk factors for PTB-HIV co-infection. RESULTS: The prevalence of PTB-HIV co-infection was 32% (286/876). Severe immunosuppression (SI) and World Health Organization (WHO) HIV clinical stage 3/4 were identified as independent risk factors for PTB-HIV co-infection in HIV infected children. The odds of PTB-HIV co-infection was increased two-fold in HIV-infected children with WHO clinical stage 3/4 compared to those with stage 1/2 (adjusted odds ratio (AOR) 1.76 [1.31-2.37], p<0.001) and 1.5-fold in children with SI compared to those without SI (AOR 1.52 [1.12-2.06], p=0.007). CONCLUSION: In our setting, the burden of PTB was high among newly diagnosed HIV-infected children, and late WHO HIV clinical stage and severe immunosuppression were associated with PTB-HIV co-infection. Therefore there is a clear need to improve strategies for early diagnosis of both HIV and PTB to optimize clinical outcomes.

Mortality among pulmonary tuberculosis and HIV-1 co-infected Nigerian children being treated for pulmonary tuberculosis and on antiretroviral therapy: a retrospective cohort study.

BACKGROUND: Mortality data, including the risk factors for mortality in HIV-infected children with pulmonary TB (PTB) being treated for PTB and who are on antiretroviral therapy (ART), are scarce in Nigeria. We determined the mortality rate and risk factors for mortality among such children, at the pediatric HIV clinic of the Jos University Teaching Hospital (JUTH) in Jos, Nigeria. METHODS: We performed a retrospective cohort study on 260 PTB-HIV-1 co-infected children, aged 2 months to 13 years, being treated for PTB and on ART from July 2005 to March 2013. The mortality rate and associated risk factors were determined using multivariate Cox proportional hazards modelling. RESULTS: The mortality rate for the study cohort was 1.4 per 100 child-years of follow-up. Median follow-up time was 5.2 years (IQR, 3.5-6.0 years) with total study time being 1159 child-years. The median age of those who died was lower than that of survivors, 1.9 years (IQR, 0.6-3.6 years) versus 3.8 years (IQR, 1.8-6.0 years), p=0.005). The majority of the deaths occurred in males (13, 81.2%), those <5 years of age (14, 87.4%) and those who had severe immunosuppression (11, 68.8%). Risk factors for death were age (with the risk of dying decreasing by 25% for every 1 year increase in age, adjusted hazard ratio (AHR)=0.75 [0.58-0.98], p=0.032), male gender (AHR=3.80 [1.07-13.5], p=0.039) and severe immunosuppression (AHR=3.35 [1.16-9.66], p=0.025). CONCLUSION: In our clinic setting, mortality among our PTB-HIV co-infected children being treated for PTB and on ART was low. However, those presenting with severe immunosuppression and who are males and very young, should be monitored more closely during follow-up in order to further reduce mortality.

Enhancement of health research capacity in Nigeria through north-south and in-country partnerships.

Research productivity in Sub-Saharan Africa has the potential to affect teaching, student quality, faculty career development, and translational country-relevant research as it has in developed countries. Nigeria is the most populous country in Africa, with an academic infrastructure that includes 129 universities and 45 medical schools; however, despite the size, the country has unacceptably poor health status indicators. To further develop the research infrastructure in Nigeria, faculty and research career development topics were identified within the six Nigerian universities of the nine institutions of the Medical Education Partnership Initiative in Nigeria (MEPIN) consortium. The consortium identified a training model that incorporated multi-institutional "train-the-trainers" programs at the University of Ibadan, followed by replication at the other MEPIN universities. More than 140 in-country trainers subsequently presented nine courses to more than 1,600 faculty, graduate students, and resident doctors throughout the consortium during the program's first three years (2011-2013). This model has fostered a new era of collaboration among the major Nigerian research universities, which now have increased capacity for collaborative research initiatives and improved research output. These changes, in turn, have the potential to improve the nation's health outcomes.

Intimate partner violence among women of childbearing age in a primary health care centre in Nigeria.

This study assessed the prevalence and characteristics of intimate partner violence among women of childbearing age in a primary health centre. With interviewer-administered questionnaire, information on partner violence was elicited from three hundred women of childbearing age selected by systematic sampling in a primary health care (PHC) centre. Over 40% had experienced violence within the last 12 months. Type of marriage and partner's education had effect on violence. Perceived reasons for violence were economic demand (56.1%), reproductive issues (42.5%), alcohol and drugs (61.2%). Forty eight per cent reported to family members. Only 1% reported to the Police. Intimate partner violence is a prevalent public health problem in eastern Nigeria. Health workers and social organisations should recognise the problem and offer necessary support, and women should be empowered to navigate through the problem.
