Factors influencing adherence to paediatric antiretroviral therapy in Portharcourt, South- South Nigeria

Introduction: The efficiency of antiretroviral therapy (ART) depends on a near-perfect level of patientfs adherence. Adherence in children poses peculiar challenges. The aim of the study was to determine the adherence level and factors influencing adherence among HIV-infected children and adolescents in University of Port Harcourt Teaching Hospital, Nigeria.  Methods: A cross-sectional survey of HIV-infected children and adolescents on ART using self-report by the caregiver/child in the past one month. Results: A total of 213 caregivers and their children were interviewed. A hundred and sixty-two (76.1%) had adherence rates .95%. Only 126 (59.2%) were completely (100%) adherent. The commonest caregiver-related factors for missing doses were forgetfulness 48(55.2%), travelled 22(25.3%) and drugs finished 16(18.4%), while the childrelated factors were refused drugs 10(11.5%), slept 8(9.2%), and vomited 8(9.2%). Sixty-eight (31.9%) caregivers reported missing clinic visit and reasons given were travelled 18(26.5%), caregiver ill 12(17.6%) and family  problems 9(13.2%). Predictors of poor adherence include mother as the primary caregiver (OR 3.32; 95%CI, 1.33-8.67), younger than 5years (OR 2.62; 95%CI, 1.30-5.31) and presence of a co-morbidity (OR 3.97; 95%CI, 1.92-8.33). Having a medication reminder strategy (OR 6.34; 95%CI, 3.04-13.31), regular clinic visits (OR 8.55; 95%CI 4.01-18.45)and status disclosure (p=0.008) predicted a better adherence. The  caregiverfs age (p= 0.11), education (p=0.86), socioeconomic status (p=0.89), gender of the child (p=0.84), type of ART (p=0.2) and duration of ART (1.0) did not significantly affect adherence. Conclusion: Adherence is still suboptimal. Since barriers to Paediatric ART adherence are largely caregiver-dependent, identifying and addressing these barriers in eachcaregiver-child pair will improve adherence and patient outcome

Effects of Different Substrates and Temperature on the Growth and Yield of Oyster Mushroom (Lentinus sajor-caju Fr.)

The study evaluated the effects of three saw dust substrates on the growth and yield of Lentinus sajor-caju at the pathology laboratory of Forestry Research Institute of  Nigeria (FRIN) under indoor and outdoor temperatures of 28.6ºC and 29.1ºC  respectively.  The saw dust substrate includes; Triplochiton scleroxylon, Gmelina arborea, and Cordia Millenii. Wheat bran and lime (CaCo3) were incorporated to the substrates as supplements.  The mycelial growth was faster at 28.6ºC giving full colonization at 3 weeks in all the substrates, while full colonization was observed in 4 weeks at 29.1ºC. T. scleroxylon substrate recorded best heights at both indoor and outdoor temperatures with 28.1±10.2cm and 14.6±4.40 respectively.  G. arborea substrate gave the highest yield at both outdoor and indoor temperatures with 69.5±30.6 g 53.5±10.8 g respectively. There was no significant difference on the growth and yield of   L. sajor-caju at the two temperature ranges. Based on the results obtained, G. arborea saw dust was the most suitable substrate and could be recommended for the cultivation of Lentinus sajor-caju

Women’s Labour Force Participation: Economic Growth Nexus in Sub-Saharan African Countries

Women’s labour force participation is an aspect of empowerment and a leeway to achieving the SDGs due to the contribution of women’s labour to economic growth. This study investigated the impact of women labour force participation on economic growth in sub-Saharan African (SSA) countries. Important lessons were drawn from Israel as to how Israel has been empowering and currently improving women’s labour force participation and economic growth in general. The study employed a two-step system Generalised Method of Moments (GMM) with panel data from 35 selected SSA countries. The findings showed a positive relationship between gross fixed capital formation, female labour force participation rate, economic growth in SSA countries, and a negative relationship between growth in the region and fertility rate. The study therefore recommended that governments should provide a policy framework to favour and encourage more women’s participation in the SSA region

Wildlife species diversity indices and seasonal distribution assessment in road-side markets of South-west Nigeria

Wildlife species are under serious exploitation by the rural populace in Nigeria because hu­man beings have understood their ecology. The need to update the existing knowledge of wildlife population is therefore essential. Twenty-three games markets along five Roads in South-west Nigeria were visited to document the wildlife displayed for sale. Two hundred and fifty copies of structured questionnaire were administered using systematic random sampling (odd) method for wildlife species information from market stakeholders. Direct method was counting for species and their numbers. Data generated were analysed through Species Diver­sity Indices Assessment. All emergent species were compared with International Union for Conservation of Nature (IUCN) abundance rating. Road seasonal distribution of the marketed wildlife was determined by percentages, standard deviation, standard error of mean, mean differences, t-test, and tests of significance and Diversity Indices. Results revealed that 69,398 wild animals were displayed. Also more wildlife were sold during rainy than dry seasons. Appropriate recommendations of government sensitization of rural and urban settlers against over-utilization of wildlife resources, encouragement of the public towards animal domesti­cation and others were made

Body Mass Index, Blood Pressure and Serum Cortisol Level as Stress Index in Symptomatic HIV/AIDS Male Subjects on Antiretroviral Therapy Negative to Malaria Parasite in Nnewi, Anambra State, Nigeria

Background: HIV infection is a risk factor for a variety of endocrine problems. Objectives: This study investigated the body mass index (BMI), Systolic blood pressure (SBP), Diastolic blood pressure (DBP) and serum cortisol level as stress factor/index symptomatic HIV/AIDS male subjects on ART who are negative to malaria parasite in Nnewi, Anambra State, Nigeria. Methods: A total of 274 adult male participants aged between 18 and 60 (42 ±13) years were randomly recruited at the Voluntary Counseling and Testing (VCT) Centre in Nnamdi Azikiwe University Teaching Hospital and grouped based on WHO criteria for staging HIV into symptomatic HIV (stage 11) infected male participants on ART (A: n=69), Symptomatic HIV subjects not on ART (B: n= 69), Asymptomatic HIV positive subjects (C: n= 68) and HIV seronegative subjects (D: n= 68). Blood samples were collected from the participants for the determination of HIV status by immunochromatography and HIV confirmation by Western Blot. Enzyme-Linked Immunosorbent Assay (ELISA) was used to assay for cortisol level. Results: The results showed a significantly increased BMI and decreased mean serum cortisol level in HIV/AIDS seropositive participants on ART than in those, not on ART (p<0.05). Also, the BMI and mean serum cortisol level were significantly decreased and increased respectively in  HIV/AIDS seropositive participants not on ART than in Asymptomatic HIV positive subjects and control respectively (p<0.05). However, the mean SBP and DBP did not differ significantly between the groups studied (p>0.05). Conclusion: This study revealed a decreased stress index in HIV/AIDS subjects on ART with hypercortisolism and lower BMI in symptomatic HIV participants, not on ART.

Natural coagulates for wastewater treatment; a review for application and mechanism

The increase of water demand and wastewater generation is among the global concerns in the world. The less effective management of water sources leads to serious consequences, the direct disposal of untreated wastewater is associated with the environmental pollution, elimination of aquatic life and the spread of deadly epidemics. The flocculation process is one of the most important stages in water and wastewater treatment plants, wherein this phase the plankton, colloidal particles, and pollutants are precipitated and removed. Two major types of coagulants are used in the flocculation process included the chemical and natural coagulants. Many studies have been performed to optimize the flocculation process while most of these studies have confirmed the hazardous effects of chemical coagulants utilization on the ecosystem. This chapter reviews a summary of the coagulation/flocculation processes using natural coagulants as well as reviews one of the most effective natural methods of water and wastewater treatment

CO2 dissolution and design aspects of a multiorifice oscillatory baffled column

Dissolution of CO2 in water was studied for a batch vertical multiorifice baffled column (MOBC) with varying orifice diameters (d0) of 6.4-30 mm and baffle open area (α) of 15-42%. Bubble size distributions (BSDs) and the overall volumetric CO2 mass transfer coefficient (KLa) were experimentally evaluated for very low superficial gas velocities, UG of 0.12-0.81 mm s-1, using 5% v/v CO2 in the inlet gas stream at a range of fluid oscillations (f = 0-10 Hz and x0 = 0-10 mm). Remarkably, baffles presenting large do = 30 mm and α = 36%, therefore in the range typically found for single-orifice oscillatory baffled columns, were outperformed with respect to BSD control and CO2 dissolution by the other baffle designs or the same aerated column operating without baffles or fluid oscillations. Flow visualization and bubble tracking experiments also presented in this study established that a small do of 10.5 mm combined with a small value of α = 15% generates sufficient, strong eddy mixing capable of generating and trapping an extremely large fraction of microbubbles in the MOBC. This resulted in increased interfacial area yielding KLa values up to 65 ± 12 h-1 in the range of the UG tested, representing up to 3-fold increase in the rate of CO2 dissolution when compared to the unbaffled, steady column. In addition, a modi fied oscillatory Reynolds number, Re′o and Strouhal number, St' were presented to assist on the design and scale-up of gas-liquid systems based on multiorifice oscillatory ba ffled columns. This work is relevant to gas-liquid or multiphase chemical and biological systems relying on efficient dissolution of gaseous compounds into a liquid medium.BBSRC -European Commissio
