The purpose of this study was to investigate the likely causes of failure of some sections of road pavements in Ajaokuta, Northcentral Nigeria. This was achieved through a geotechnical assessment of subgrade soils in affected areas.

The methods entailed field and laboratory methods and statistical analysis. Subgrade soil samples were retrieved from a depth of 1,000 mm beneath the failed portions using a hang auger. The soils were analyzed for natural moisture content (NMC), Atterberg limit (liquid limit, plastic limit and linear shrinkage), grain size distribution, compaction and California bearing ratio (CBR), respectively.

The results of the geotechnical tests ranged from NMC (12.5%–19.4%), sand (84%–98%), fines (2%–16%), LL (16.0%–32.2%), PL (17%–27.5%), LS (2.7%–6.4%), PI (2.5%–18.4%), maximum dry density (1756 kg/m2–1961 kg/m2), optimum moisture content (13.2%–20.2%), unsoaked CBR (15.5%–30.5%) and soaked CBR (8%–22%), respectively. Pearson’s correlation coefficient performed on the variables showed that some parameters exhibited a strong positive correlation with r2 > 0.5.

Funding was the main limitation.

Comparing the results with Nigerian standards for road construction, and the AASHTO classification scheme, the subgrade soils are competent and possess excellent to good properties. The soils also exhibited very low plasticity, a high percentage of sand, high CBR and low NMC, which implies that it has the strength required for road pavement subgrades. The likely causes of the failures are, therefore, due to the use of poor construction materials, technical incompetence and poor compaction of sub-base materials, respectively.

Women experience a triple burden of ill-health spanning non-communicable diseases (NCDs), reproductive and maternal health conditions and human immunodeficiency virus (HIV) in sub-Saharan Africa. Whilst there is research on integrated service experiences of women living with HIV (WLHIV) and cancer, little is known regarding those of WLHIV, diabetes and/or hypertension when accessing integrated care. Our research responds to this gap.

The INTE-AFRICA project conducted a pragmatic parallel arm cluster randomised trial to scale up and evaluate “one-stop” integrated care clinics for HIV-infection, diabetes and hypertension at selected primary care centres in Uganda. A qualitative process evaluation explored and documented patient experiences of integrated care for HIV, diabetes and/or hypertension. In-depth interviews were conducted using a phenomenological approach with six WLHIV with diabetes and/or hypertension accessing a “one stop” clinic. Thematic analysis of narratives revealed five themes: lay health knowledge and alternative medicine, community stigma, experiences of integrated care, navigating personal challenges and health service constraints.

WLHIV described patient pathways navigating HIV and diabetes/hypertension, with caregiving responsibilities, poverty, travel time and cost and personal ill health impacting on their ability to adhere to multi-morbid integrated treatment. Health service barriers to optimal integrated care included unreliable drug supply for diabetes/hypertension and HIV linked stigma. Comprehensive integrated care is recommended to further consider gender sensitive aspects of care.

This study whilst small scale, provides a unique insight into the lived experience of WLHIV navigating care for HIV and diabetes and/or hypertension, and how a “one stop” integrated care clinic can support them (and their children) in their treatment journeys.
