- Description: Economic development relates to economic growth and improvements in the living standards of people. South Africa is ranked among the slow developing countries in the world, based on the high percentage of people living under poor conditions. This study examines the relationship between government health expenditure and economic development in South Africa between 1994 and 2022. Human development index (HDI), government health expenditure (GHE), inflation, population growth, and unemployment are the variables used to investigate this relationship. Auto regressive distributed lag (ARDL) and Granger causality were employed to examine this relationship. Government expenditure on health services and inflation were found to have a positive short-run and long-run relationship with human development index, whereas unemployment and population growth showed a negative relationship with HDI in the long-run. Granger causality results highlighted a unidirectional causality between HDI and GHE in South Africa, among other explanatory variables. HDI Granger causes GHE and vice versa. Continuous increment and monitoring of GHE distribution, to ensure that the growing population receives proper healthcare to boost the life expectancy of the citizens and to fund the preventative measures against health epidemics in South Africa is the policy recommendation to improve HDI in South Africa.

- Description: Food security remains a critical issue worldwide, and South Africa is no exception. This national challenge is especially acute in the Eastern Cape Province, known as one of the poorest regions in the country. The highest rates of poverty are observed in the Eastern Cape Province, with the population largely dependent on social grants to secure their food needs. The primary objective of the study was to examine the household food security status and its determinants in Mthatha, Eastern Cape Province of South Africa. The study was conducted in Tabase and Ncise in Mthatha. The purposive sampling technique was employed in the study and 336 data points were achieved. The study used the Household Food Insecurity Access Scale (HFIAS), developed by the USAID-funded Food and Nutrition Technical Assistance II (FANTA), and leveraged Tobit regression analysis, particularly advantageous for handling censored dependent variables, to examine the determinants of food household food security. The results revealed that gender, age, crops and social grants have no statistical significant relationship with food insecurity. Education, employment status, income, livestock and dietary diversity have a statistical significant relationship with food insecurity. Results further revealed that 40.36% of households were food insecure while 4.22% were food secure, 7.83% were mildly food insecure and 40.36% were severely food insecure. The study recommends the formation of agricultural cooperatives with government support, prioritising education incentives, and strengthening existing food support initiatives. It emphasizes promoting savings clubs and subsidising nutrient-rich foods to enhance accessibility. These multifaceted recommendations aim to address household food security in Mthatha, providing a comprehensive framework for intervention and policy considerations. , Thesis (Masters) -- Faculty of Economics and Finacial Sciences, 2024

- Description: To be balanced, education should enhance the development of intellectual, emotional, physical, social, moral, occupational, and financial capabilities. In South Africa's secondary education system, entrepreneurship education is aimed at developing learners’ knowledge and skills for self-sustainability and economic development. The emergence of small businesses is one of the main forces behind a country’s economy and has a significant impact on economic expansion, job creation, and the country's ability to compete internationally. Using the human capital theory, this study aimed to explore how Consumer studies can enhance the acquisition of entrepreneurial knowledge and skills among learners in selected secondary schools in the Eastern Cape province, South Africa. The study is lensed within constructivism paradigm, with a qualitative research approach, case study design, and purposively sampled fourteen participants. Eight educators from eight public secondary schools (four in the Amathole Education District and four in Mnquma Education District), four principals (two from each education district) and two subject advisors (one from each education district) were sampled for the study. Data were collected through face-to-face semi-structured interviews, thematically analysed, and presented according to themes derived from the findings. The study revealed several varied views and experiences on the role of consumer studies in the enhancement of knowledge and skills in entrepreneurship. The findings revealed challenges experienced in the offering of Consumer studies, which include but are not limited to the shortage of adequately trained educators, inappropriate infrastructure, large learner numbers, minimal financial support, and a lack of instructional materials. If left unaddressed, these issues have the potential to undermine the value of Consumer studies as a vehicle for empowerment and change. Recommendations include targeted curriculum revision to streamline content, embracing learner-centred approaches, prioritising subject-oriented professional development, integrating technology for enhanced learning experiences, improving financial support and provision of relevant infrastructure.

- Description: The ability of markets to communicate food price signals at different levels of marketing chains is critical to understanding the nature of the competition in the chain, and development of strategies to address challengers of information symmetry and food insecurity. This study examined vertical transmission of wheat price among the main value chain, looking at the pricing behaviour of certain role players in the wheat production/supply and distribution of bread which is a major staple food consumed in South Africa. A nonlinear autoregressive distributed lag model (NARDL) model was used to analyse the yearly time series data for the period of 2000 to 2022. The results of the stationarity test showed that all variables were of order one, I(1). The study used two pairs, namely farmgate price and retail price and farmgate price and wholesale price, to examine the existence of asymmetry between these prices, with rainfall and temperature as control variables. The results indicate the existence of positive long-run asymmetry of 35,9% between farmgate price of wheat and retail price of bread, and 3,49% asymmetry between farmgate price and wholesale price of wheat. In order to develop informed policies on food security, this study suggests that the government should enhance regular access to data and sustain its monitoring and communication of food price information across the whole country. The other thing that is recommended by the study is the provision of subsidies for wheat farmers to help the wheat industry, reduce the cost of bread production, and make bread more affordable and accessible for consumers. , Thesis (Masters) -- Faculty of Economic and Financial Sciences, 2024

- Description: IAntiretroviral therapy (ART) is the standard treatment for human immunodeficiency virus (HIV). The treatment reduces HIV load to low level, relegating the disease from an acute infection to a chronic condition. Of late, there have been increased reports associating ART with increased cardiovascular disease (CVD) risk, further reducing the possibility of complete positive health outcomes for people living with HIV (PLWH). Poor adherence to the ART has been implicated in the development of some CVD risk factors but levels of adherence is not well known in the Eastern Cape. Thus, this study was designed to determine the level of ART adherence and associated cardiovascular risk factors. A cross-sectional study of a 100 participants was conducted to determine ART adherence and prevalence CVD risk factors in Mthatha. Both Male and female participants above 18 years of age were selected and ART adherence was determined using the adherence in chronic diseases scale (ACDS). The lipid profile, anthropometric measurements, and clinical parameters were used to determine CVD risk factors. Regression models were fitted to determine the association between adhrence and CVD risk factors in PLWH. All statistical analysis was performed using the statistical package for social sciences (SPSS) version 28, and the statistical significance was set at The average adherence rate was found to be 90.35% population of PLWH sampled, and 30% participants were found to have the optimum adherence rate ≥95%, which considered be adequate to effect viral progression. The prevalence of CVD risk factors was found to be 97%, with 46% of the participants having CVD. Although it was not statistically significant, the regression analyses indicated that non-adherent patients were more likely to report presence of CVD risk factors. This suggests that sub-optimal adherence to ART may be a contributing factor towards CVD risk development in patients on ART. It is possible that the results are clinically significant but there is a need to collect more data to increase the statistical power of the study , Thesis (Masters) -- Faculty of Medicine and Health Sciences, 2023

- Description: Pulmonary tuberculosis remains the leading cause of death in developing countries, it is an ancient disease that was discovered in the eighteenth centuries. The World Health Organization (WHO) tuberculosis (TB) regimen entails the first line drugs, rifampicin, isoniazid, ethambutol, and pyrazinamide. These drugs are taken for long periods and the load is high, they carry some side effects like liver damage and peripheral neuropathies, hence pyridoxine that is administered with TB treatment to mitigate the toxic effects to peripheral nerves. Drug resistance has emerged because of unbearable side effects of TB treatment in TB patients. In view of all these collective challenges of TB drugs, this study draws its motivation towards exploring natural products in the form of medicinal plants toward inventing new therapies that could be easily available and safer, and the macrophages were considered the therapeutic target for this study as they are the primary cells that get infected by Mycobacterium in the lung. Therefore, the study aimed at screening medicinal plants used by traditional healers and herbalists for the management and control of signs and symptoms related to pulmonary tuberculosis, for potential immunomodulatory activity on RAW 264.7 cells, and the objectives were; to obtain information on indigenous plants used to treat pulmonary tuberculosis (PTB) from traditional healers and herbalist, to test the cytotoxicity of crude extracts on macrophages and hepatocytes (C3A cells), to determine the polarizing effects of crude extracts on macrophages, to determine the polarizing effect of the crude extract fractions on macrophages and to finally isolate and characterize the compounds in active fraction. vii All medicinal plants investigated in this study were collected through ethnobotanical survey, authenticated in Botany Department, dried, and extracted in 70% ethanol solvent. The dried crude extracts were screened for toxicity using 3-4,5-dimethylthiazole-24-25 diphenyl tetrazolium bromide (MTT) technique on RAW264.7 macrophages and dual fluorescence staining technique on C3A cells at concentration 50, 100 and 200μg/ml in cell culture system. Seven medicinal plants displayed dose dependency toxicity, while three plants did not show any signs of toxicity with cell viability maintained at 100%. The three medicinal plants (Anthrixia phylicoides, Lippia javanica and Sanicula elata) were further investigated for immunomodulatory activity (Griess method) and antioxidant activity (CellROX® Orange and Hoechst 33342). Lippia and Anthrixia were found to be anti-inflammatory with low amounts of nitric oxide (NO) production, while Sanicula displayed a considerable amount of nitric oxide when compared to the lipopolysaccharides (LPS) control. NO was the biological marker measured that demonstrated the immunomodulatory effect of plants on macrophages. Furthermore, the two plants showed antioxidant activity on liver cells at higher concentration (100 and 200μM) while Sanicula exhibited antioxidant activity across all tested concentrations. Compound profiling for Sanicula was therefore determined by UPLC-MS hyphenation technique and the major compounds profiled were phenolic compounds. The crude extracts of Sanicula were further partitioned into five fractions using partition solvent technique (n-hexane, Dichloromethane, ethyl acetate, N-butanol, and water). Anti-inflammatory activity was repeated on the five fractions, and Dichloromethane fraction and water fraction drove the macrophage switching towards the M1 phenotype viii with considerable amount of NO produced. Compound isolation and identification was conducted through chromatography techniques, and ten samples (S1-S10) were isolated. The samples were further subjected to NMR-Spectrometry analysis for elucidation and characterization of isolated compounds, and S1, S7, S9, S10 were final compounds. RAW 264.7 cells were again treated with the four compounds and results indicated absence of NO production, the opposite of the two previous outcomes where there was clear evidence of immunomodulation. The results obtained from the compounds has indicated that drugs work in synergy, and in combination, like TB treatment which is taken as combination of all drugs. We therefore conclude that indeed Sanicula immunomodulated RAW264.7 macrophages, and we present a strong observation of macrophage polarization from M0 phenotype to M1 phenotype which is capable of degrading and destroying Mycobacterium, and the antioxidant activity of the crude extracts of this medicinal plant. We therefore recommend further studies in the animal disease model. , Thesis (D.Ed) -- Faculty of Medicine and Health Sciences, 2023

- Description: Psychiatric patients are known to have an increased risk of adverse outcomes from COVID-19. Some psychiatric medications are known to have cardiometabolic and immune system-related side effects and have been found to either protect from or worsen outcomes in COVID-19 illness. The interaction of COVID-19 with the cardiometabolic and immune-related aspects of psychiatric illness and treatment has not been sufficiently studied in people with mental illness. Aim: To describe the clinical and demographic characteristics, and clinical outcomes of adult inpatients at Fort England Psychiatric Hospital who contracted SARS-CoV-2 during the first wave of the COVID-19 pandemic, including statistical and case analyses of COVID-19 related deaths. Methods: The study was conducted at Fort England Hospital (FEH). Data were obtained from patient files, treatment charts, and the hospital's COVID-19 reporting schedules. Sixty-four patients were diagnosed with COVID-19 during the first wave of infections in the hospital, and five of them died. A cross-sectional research design was adopted, in which the COVID-19 outcomes of the 64 patients were described alongside their psychiatric disease and treatment factors. Descriptive statistics were used to describe the characteristics of the participants. Fisher’s exact test for contingency tables and Cramér's V effect size were computed to identify possible associations between death and specified clinical variables. Additionally, case analyses were carried out on each patient who died based on participant case notes. Results: The incidence of SARS-CoV-2 infections was 21.8% during the first wave of infections, and the case fatality rate was 7.8%. A significant association was ii found between higher age and COVID-19 related death (Fisher’s exact test p = 0.010). Two-thirds (68%) of the patients who recovered were younger than 45, whereas one of the five patients who died (20%) fell in this age group. Race was also strongly related to COVID-19 outcomes, with coloured comprising 80% of the participants who died compared to 80% of black African patients in the recovered group (Fisher’s exact test p = 0.012). All patients who died had co-morbid medical conditions compared to 58% of those who recovered, although this relationship was weak (Fisher’s exact 1-sided test p = 0.076). However, case analyses for the patients who died revealed recurring themes of multiple psychiatric comorbidities, proneness to psychotropic treatment side effects, and a history of frequent relapses among most of these patients. All who died were faced with adversity and dire life circumstances. Conclusions: This study contributes to a better understanding of clinical, demographic and social variables that impacts COVID-19 outcomes in an in-patient psychiatric population. first wave of the COVID-19 pandemic in patients with serious mental illness in an inpatient population. More studies of a larger scale are needed to describe the COVID-19 pandemic among psychiatric populations and to investigate factors that contribute to the vulnerability of psychiatric patients to adverse outcomes of COVID-19. , Thesis (Masters) -- Faculty of Medicine and Health Sciences, 2023

Two-thirds (68%) of the patients who recovered were younger than 45, whereas one of the five patients who died (20%) fell in this age group. Race was also strongly related to COVID-19 outcomes, with coloured comprising 80% of the participants who died compared to 80% of black African patients in the recovered group (Fisher’s exact test p = 0.012). All patients who died had co-morbid medical conditions compared to 58% of those who recovered, although this relationship was weak (Fisher’s exact 1-sided test p = 0.076). However, case analyses for the patients who died revealed recurring themes of multiple psychiatric comorbidities, proneness to psychotropic treatment side effects, and a history of frequent relapses among most of these patients. All who died were faced with adversity and dire life circumstances. Conclusions: This study contributes to a better understanding of clinical, demographic and social variables that impacts COVID-19 outcomes in an in-patient psychiatric population. first wave of the COVID-19 pandemic in patients with serious mental illness in an inpatient population. More studies of a larger scale are needed to describe the COVID-19 pandemic among psychiatric populations and to investigate factors that contribute to the vulnerability of psychiatric patients to adverse outcomes of COVID-19. , Thesis (Masters) -- Faculty of Medicine and Health Sciences, 2023

- Description: External beam radiotherapy with a moderate hypofractionated regimen has largely replaced conventional schedules. The change in regimen is based on the premise that prostate cancer, due to its low the alpha/beta ratio, demonstrates a higher sensitivity to a larger dose per fraction of radiation. Prostate Specific Antigen (PSA) is a specific indicator of prostate cancer treatment outcomes. The serum PSA trend is an indication of treatment response and risk for relapse. The time to nadir and the value of the PSA nadir are important predictors of biochemical control or failure. The lower the PSA level, the more durable the probability of maintained biochemical disease free survival. This study focuses on the biochemical control of patients treated with two different fractionation regimens at Frere Hospital. Aim To illustrate that the use of a moderate hypofractionated regimen for the treatment of intermediate and high risk prostate cancer is non inferior to a conventional regimen. Methodology The study took place at the department of radiation oncology, Frere Hospital, East London, Eastern Cape, South Africa. The study population consisted of 26 patients treated with conventional fractionation (2.00Gy x 36 fractions) in 2018 and 36 patients treated with the newly adopted hypofractionated regimen (3.00Gy x 20 fractions) in 2019. A comparison is made of the post treatment PSA trend over a 24 month period. Impact of study The study is projected to support the change in fractionation regimens at an institutional level. 2 Results: 41.9% of patients were enrolled in the conventional regimen, 58.1% were enrolled in the moderately hypo-fractionated arm. The participants were classified into high risk and intermediate risk in the two treatment arms and these were distributed equally. There was a clear decline in the serum PSA values over the two-year follow-up period. All four groups showed a similar pattern in that from the baseline to the first quarter, there was a sharp decline in the serum PSA values and this was significant for all four groups , Thesis (Masters) -- Faculty of Medicine and Health Sciences, 2023

- Description: Background: This study examined Nigeria’s socio-demographic profiles and health service utilization patterns of Patent Medicine Vendors (PMVs) and Community Pharmacists (CPs). Method: A cross-sectional study using a structured self-administered questionnaire among 405 retail outlets (322 PMVs and 83 CPs) across 16 Lagos and Kebbi Local Government Areas (LGAs) between June 2020 and December 2020. Results: Results showed that 60.4% were male, 76.3% from Lagos, 58.3% had tertiary education, and 74.1% had medical training. Cough and fever were common symptoms. Significant differences were found in the utilization of STD services (PMVs: 9.2%, CPs: 12.3%, p = 0.03)), services by age < 0.001), and utilization by males (PMVs: 50.8, CPs: 47.1, p = 0.013). The study revealed that men visited PMVs more, while CPs used more STI services and childhood visits. Conclusions: The findings suggest that expanding health services among PMVs could target male-dominant diseases, and capacity building of CPs on syndromic STI management could reduce the STI burden.

- Description: ABSTRACT Background: Despite increased access to ultrasound machines across the country, there are no guidelines on the required competency level in point of care ultrasound (POCUS) for medical doctors working in district hospitals in South Africa. Through a Delphi process involving nominated experts across the country, this study aimed to develop and achieve expert consensus on the POCUS skillsets required for medical doctors working at district hospitals in South Africa. Methods: A Delphi method of consensus development was performed, comprising several iterative rounds of skillset selection that continued until consensus was achieved on all items. We started this process using the existing American Academy of Family Physicians’ ultrasound curriculum (93 skillsets) as the starting point in the questionnaire. Experts were drawn from across the country; two from district hospitals in each province and two from each academic Family Medicine Department (N=36). In each iterative round, participants were asked to identify which POCUS skillsets were essential, optional (region specific) or non-essential for South African district hospitals. Results: Overall, five iterative rounds were required before consensus was attained on all skillsets (>70% agreement among the experts). In the first round, consensus was reached on 14 skillsets, followed by 21 skillsets in the second and third rounds. In the fourth round, consensus was reached on 26 skillsets, and in the fifth and final round, consensus was reached on the remaining eight skillsets. Of the starting 93 skillsets, three skillsets could not achieve consensus , Thesis (Masters) -- Faculty of Medicine and Health Sciences, 2023

- Description: The truncated snail, C e rit hid e a d e c olla t a , is one of the major invertebrates in mangrove ecosystems. It’s the rapid ecophysiological response to environmental stress conditions makes C. decollata an ideal species to test the effects of climate change in mangrove ecosystems. Increased temperatures, due to climate change, is one of the major threats faced by aquatic invertebrates as thermal stress may easily lead to death. This study, thus, compared the effects of 1) environmental conditions on the morphology; 2) temperature on body weight and stoichiometry as well as 3) the heavy metal content of C. decollata across three mangrove ecosystems. Morphometry results revealed that sites significantly influenced most of the shell morphological variables (i.e., shell length, shell width, spire height and aperture width). However, sites did not significantly influence the shell depth and aperture length of C. decollata . Temperature effects on body weight revealed that C. decollata individuals gained weight at low temperatures (10 to 20 °C) in all sites. As a result, the mean % weight gain of 6.75 ± 0.11 in Mngazana, 15.82 ± 0.13 in Mbhashe and 11.2 ± 0.13 in Nqabara. Contrary, C. decollata lost weight at temperatures between 25 and 40 °C across all sites leading to a mean % weight loss of 9.51 ± 0.05 in Mngazana; 14.52 ± 0.16 in Mbhashe and 25.74 ± 0.12 in Nqabara. Stoichiometric analysis revealed that soft tissues had higher nitrogen, carbon and phosphorous than the shells. The NP ratio was higher in soft tissues than in shells while CN and CP ratios were higher in shells than in soft tissues. The N, C, P, CN, CP and NP were lowest in Mngazana and highest in Nqabara. Temperature increases resulted in increased nitrogen, phosphorous, carbon and their stoichiometric CN, CP and NP ratios. Heavy metal results showed that Zn, Cu and Cd were highest in the soft tissue than in the shells and sediment. Contrarily, Fe and Pb were higher in the sediment than in shells and soft tissues. The Cu+Zn was highest in the shells than in the soft tissues and sediment. However, arsenic concentrations were below detection levels across all sites. Overall, no significant site differences were detected for heavy metals. It was, therefore, concluded that sites influenced some of C. decollata morphological features while temperature affected the body weight and stoichiometry of C. decollata . , Thesis (Masters) -- Faculty of Natural Sciences, 2023

- Description: This study sought to explore the challenges experienced in reading and writing English First Additional Language by learners in rural Grade 4 classes at Lusikisiki, in O.R. Tambo Coastal District. There are common reading and writing challenges in English FAL learners in Grade 4 classes. The pragmatism paradigm was employed in this study. A mixed methods approach was used through quantitative and qualitative approaches. I used three research designs, that is, case study, explanatory research and descriptive research design since this study is a mixed method. I sampled 10 primary schools to participate in this research. These were purposively sampled as: 20 Grade 4 English FAL teachers (2 per school) to answer semi-structured interviews close-ended questionnaires, 100 Grade 4 learners (10 learners per school) were also randomly sampled to answer close-ended questionnaires. Classroom observations were used to observe the reading lessons; terms 3 and 4 written work of Grade 4 English FAL learners for data collection was examined. Collected data were analysed by means of Applied Thematic Analysis (ATA) where themes and categories emerged; the Statistical Package for Social Sciences (SPSS) was used where findings were presented in the form of frequency tables (cross-tabulations), histograms and pie charts. Findings from analysed data revealed major reading and writing challenges, such as spelling, punctuation, paragraphs, word recognition, pronunciation, sentence construction and comprehension. The study revealed that these challenges were caused by the following factors: no reading and writing clubs, English is not the mother tongue of learners, teachers rushing the syllabus, overcrowded classrooms, shortage of LTSM, parental involvement being minimal and transition from Foundation Phase to Intermediate Phase. Based on the findings, recommendations were made. These are the reduction of workload for teachers, libraries to be built in schools and communities and integration of teachers and parental support. , Thesis (D.Ed) -- Faculty of Education Sciences, 2023

- Description: These days, aquatic (fish) welfare is a major issue and a significant component that affects fish output. Although numerous factors can be involved, climate-induced floods are one of the most critical limiting factors in the aquaculture and fisheries industry’s development. Understanding the extent of losses and damages caused by floods at the farm level will thereby exacerbate pre-emptive policy responses. Thus, the impact of floods on fish production by focusing on catfish earthen pond-based farmers in Southwest Nigeria is presented. A survey is conducted for 150 fish farms in the region. A marginal treatment effects (MTE) approach is employed to determine the heterogeneity across the households and the policy-relevant treatment effects (PRTE). The results show significant heterogeneity in the effects of floods on fish production, considering both observed and unobserved characteristics of the farmers. It is shown that flood significantly increases output loss. Furthermore, farmers with high propensity scores to flood tend to have a high likelihood of incurring output loss. The estimates of PRTE reveal that relaxing policy strategies, such as access to climate information and climate-related training and workshops, would significantly exacerbate output loss due to flood incidences. Thus, intensifying awareness and sensitization on climate change policies will address the flood menace and still increase food production.

- Description: Abstract The study examined the impact of Sustainable Tax Revenue and Expenditure on the achievement of Sustainable Development Goals in African countries using secondary data. The dataset was extracted from the World Development Indicators database. The large gap between developed and developing countries when comparing the probability of them achieving the SDGs was the main motivation behind this study. Data retrieved from 45 countries comprised of both African and developed countries for the period 2010–2020 was analyzed using the Generalized Method of Moments technique. The results revealed that the coefficients of grants received, various forms of taxes, and other revenue have a positive effect on economic growth but a negative effect on poverty and unemployment for African and developed countries. This finding suggests that improvements in tax revenue generation, grants and other revenue accumulation across different sources boost economic performance and the welfare of individuals in the analyzed countries. The outcome is an indication that accumulating more grants from different sources will help to achieve sustainable development, improve financial stability, contributes to the economic growth and development in these countries. This study can guide policymakers, governments, international institutions, revenue bodies such as SARS and other stakeholders in their various planning and other decision-making endeavors. Governments and other policymakers must ensure the efficient generation and sustainable utilization of revenue generated from taxes and other revenues to spur the growth and development of their countries. They should have Growth-Sustainability-Oriented Fiscal Adjustment Programs and Sustainable Government Expenditure that can help push and redirect governments to achieve the SDGs in Africa.

- Description: Agricultural waste is enriched with a variety of environmentally friendly materials that can potentially boost economic growth, reduce the spread of contagious diseases, and serve as a carbon-free renewable energy bioresource. Biopolymers produced from agricultural waste have a range of applications in medicine, agriculture, pharmaceutics, and industrial factories. The chemical extraction of biopolymers from biomass requires a series of alternating alkali, acid, and alkali treatments at controlled temperatures. Chemical extraction of plant-based biopolymers requires elevated temperatures (70–100°C), while for animal and sea organism-based biopolymers, moderate temperatures of 25–60°C are used. The obtained biopolymers are functionalized into various materials for application in a wide range of industries. The reported functional materials are loaded with inorganic nanomaterials, plant extracts, and organic compounds, which resulted in a synergistic effect and enhanced activity of the materials. Several researchers have synthesized biopolymers with synthetic polymers to improve their bioavailability, tensile strength, shelf life, and UV adsorption. This review article reports the extraction techniques of biopolymers from agricultural waste and their application in wound healing, water treatment, food storage, passive cooling, and cosmetics. The dearth of scientific articles on the applications of biopolymers generated from agricultural waste produced from food crops grown in Africa is a motivation for the present compilation.

- Description: Agricultural waste is enriched with a variety of environmentally friendly materials that can potentially boost economic growth, reduce the spread of contagious diseases, and serve as a carbon-free renewable energy bioresource. Biopolymers produced from agricultural waste have a range of applications in medicine, agriculture, pharmaceutics, and industrial factories. The chemical extraction of biopolymers from biomass requires a series of alternating alkali, acid, and alkali treatments at controlled temperatures. Chemical extraction of plant-based biopolymers requires elevated temperatures (70–100°C), while for animal and sea organism-based biopolymers, moderate temperatures of 25–60°C are used. The obtained biopolymers are functionalized into various materials for application in a wide range of industries. The reported functional materials are loaded with inorganic nanomaterials, plant extracts, and organic compounds, which resulted in a synergistic effect and enhanced activity of the materials. Several researchers have synthesized biopolymers with synthetic polymers to improve their bioavailability, tensile strength, shelf life, and UV adsorption. This review article reports the extraction techniques of biopolymers from agricultural waste and their application in wound healing, water treatment, food storage, passive cooling, and cosmetics. The dearth of scientific articles on the applications of biopolymers generated from agricultural waste produced from food crops grown in Africa is a motivation for the present compilation.

- Description: In the present study, a nanocomposite was prepared for the removal of dye from the aqueous phase. In this regard, multiwalled carbon nanotubes (MWCNTs) were anchored on the stalk of Solanum melongena (SMB) to obtain a robust adsorbent with the capacity to eliminate reactive blue 19 (RB19) using the batch adsorptive processes. Solanum melongena stalk decorated with MWCNTs (SMC) and SMB were characterized using Thermogravimetric analysis (TGA), Brunauer–Emmett– Teller (BET), Field emission scanning electron microscopy (FESEM) and Fourier transform infrared spectroscopy (FTIR) analysis. With the exception of solution pH, an increase in contact time, adsorbent dose, initial RB19 concentration, and solution temperature were noticed to elevate the uptake potential of SMB and SMC. Kinetic experimental data for SMB and SMC were consistent with the pseudo-second-order and Elovich model, respectively. The experimental isotherm data obtained for SMB and SMC were best expressed by Freundlich and Langmuir models, respectively. After the fifth adsorption–desorption cycle, SMC exhibited 52% of adsorption efficiency. Hence, SMC can be an auspicious candidate for the efficient adsorption of RB19.

- Description: In African countries, including Angola, antenatal care (ANC) coverage is suboptimal and maternal mortality is still high due to pregnancy and childbirth-related complications. There is evidence of disparities in the uptake of ANC services, however, little is known about both the socio-economic and geographic-based disparity in the use of ANC services in Angola. The aim of this study was to assess the extent of socio-economic, urban-rural and subnational inequality in ANC coverage in Angola. We analyzed data from the 2015 Angola Demographic and Health Survey (ADHS) using the World Health Organization (WHO) Health Equity Assessment Toolkit (HEAT) software. The analysis consisted of disaggregated ANC coverage rates using four equity stratifiers (economic status, education, residence, and region) and four summary measures (Difference, Population Attributable Risk, Ratio and Population Attributable Fraction). To measure statistical significance, an uncertainty interval (UI) of 95% was constructed around point estimates. The study showed both absolute and relative inequalities in coverage of ANC services in Angola. More specifically, inequality favored women who were rich (D = 54.2, 95% UI; 49.59, 58.70, PAF = 43.5, 95% UI; 40.12, 46.92), educated (PAR = 19.9, 95% UI; 18.14, 21.64, R = 2.14, 95% UI; 1.96, 2.32), living in regions such as Luanda (D = 51.7, 95% UI; 43.56, 59.85, R = 2.64, 95% UI; 2.01, 3.26) and residing in urban dwellings (PAF = 20, 95% UI; 17.70, 22.38, PAR = 12.3, 95% UI; 10.88, 13.75). The uptake of ANC services were lower among poor, uneducated, and rural residents as well as women from the Cuanza Sul region. Government policy makers must consider vulnerable subpopulations when designing needed interventions to improve ANC coverage in Angola to achieve the 2030 Sustainable Development Goal of reducing global maternal mortality ratio to 70 deaths per 100,000 live births.
