RESUMO

Primary healthcare facilities lack routine diagnostic screening due to resource limitations and dependence on syndromic management, resulting in an unprecedented prevalence and incidence of sexually transmitted infections (STIs), particularly among key and priority populations. Specific focuses are essential to strengthen current STI control measures. Therefore, this article describes the protocol for evaluating STI programme among key and priority populations in selected primary healthcare facilities in South Africa. We will employ an exploratory, descriptive research design to assess the STI programme in terms of its facility operations, functions, scope, gaps, delivery services, STI surveillance methods, and indicators in the selected primary healthcare facilities. A purposive sample of 15-20 STI programme stakeholders will be selected from five primary healthcare facilities in Limpopo Province, South Africa. The programme evaluation will use the World Health Organization assessment checklist tool, a globally recognised and validated instrument comprising open- and closed-ended questions to assess the STI programme. This tool, known for its credibility and reliability, ensures the study's validity. Quantitative data will be captured on STATA software (College Station, TX, USA) version 18 for descriptive analysis and presented as the mean and standard deviation for continuous variables, proportions and percentages for categorical variables. A p ≤ 0.05 will demonstrate a statistically significant level. Thematic content analysis will be conducted for the qualitative data using Atlas. ti software (Technical University, Berlin, Germany) version 23.1. The study's results will inform new approaches to strengthen STI coverage, service delivery, and linkage to care.

RESUMO

BACKGROUND: Substance use is an escalating public health problem in South Africa resulting in risky behaviours and poor educational attainment among adolescents. There is a huge battle to overcome substance use among learners as more drugs become easily available with the mean age of drug experimentation reported to be at 12 years of age. It is important to continuously understand the trends in substance use in order to assess if there are positive changes and provide evidence for the development of context-specific effective interventions. This paper outlines the prevalence of substance use among selected high schools in a district in Limpopo province. METHODS: To determine the prevalence of substance use among selected high school learners in a district in Limpopo Province, a cross-sectional school survey of 768 learners was conducted. Data was analysed using SPSS v 26. Descriptive analysis was used to describe the independent and dependent variables and Chi-Square test was used to investigate associations between demographic characteristics and substance use among high school learners. RESULTS: The most abused substances by learners were alcohol (49%), cigarettes (20.8%) and marijuana (dagga/cannabis) (16.8%). In a lifetime, there was a significant difference (P < 0.05) in cigarette smoking with gender, school, and grade; with more use in males (14.2%) than females (7.6%); in urban schools (14.6) than peri-urban (6.7%) and more in Grade 12 (6.4%). There was a significant difference (P < 0.05) in alcohol use with more use in Grade 10 (12.6%) and varied use among male and female learners but cumulatively more alcohol use in females (27.7%). Drug use varied, with an overall high drug use in urban schools (20.7%). CONCLUSIONS: Substance use is rife among high school learners in the district and health promotion initiatives need to be tailored within the context of socio-demographic characteristics of learners including the multiple levels of influence such as peer pressure, poverty, unemployment and child headed families. Additional research is required to investigate the factors leading to a notable gradual increase in use among female learners and into the environmental and family settings of learners in influencing substance use.

RESUMO

In semi-arid sub-Saharan Africa, climate change and the intensification of human activities have altered the hydrological balance and modified the recurrence of extreme hydroclimatic events, such as droughts and floods. The geomorphological heterogeneity of river catchments across the region, the variable human pressure, and the lack of continuous hydroclimatic data preclude the definition of proper mitigation strategies, with a direct effect on the sustainability of rural communities. Here, for the first time in Africa, we characterize hydrological extreme events using a multidisciplinary approach that includes sedimentary data from dams. We focus on the Limpopo River basin to evaluate which factors control flood magnitude since the 1970. Extreme flood events were identified across the basin in 1988-89, 1995-96, 1999-2000, 2003-04, 2010-11, 2013-14 and 2016-17. The statistical analysis of sedimentary flood records revealed a dramatic increase in their magnitude over the studied period. A positive correlation between maximum river flow and antecedent prolonged drought conditions was found in South Africa and Mozambique. Most importantly, since 1980, we observed the likely decoupling of extreme floods from the magnitude of La Niña events, suggesting that the natural interannual variability driven by El Niño-Southern Oscillation (ENSO) has been disrupted by climate changes and human activities.

RESUMO

BACKGROUND: Keratoconus (KC) is a progressive condition that usually affects young persons between their first and fourth decades. Myopia and irregular astigmatism are the common presentations which are proceeded by corneal steepening and thinning. Keratoconus is a progressive ectasia of the cornea that presents bilaterally, although often asymmetrical. AIM: To explore the experiences of KC patients attending public eye care facilities in Capricorn District of Limpopo province. SETTING: Capricorn District, Limpopo province, South Africa. METHODS: Descriptive qualitative phenomenology approach was used in the study to explore the lived experiences of patients diagnosed with KC, attending public eye care facilities. Purposive sampling was used to select 16 patients who were diagnosed with KC and referred for contact lens fitting. Data were collected through face-to-face, one-on-one interviews. RESULTS: Patients reported to have developed gradual vision loss which worsened when they grew older. There was lack of knowledge of KC amongst patients and this was exacerbated by limited health literacy and vocabulary barriers. Patients had difficulty performing daily activities where some had dropped out of school while others worked at a slower pace and reduced working distances. CONCLUSION: Patients with KC received inadequate information on their condition due to limited health literacy and vocabulary barriers. Programmes to promote practitioner and patient education are required to improve the perceived service level provided to KC patients.Contribution: The findings of this study will assist to improve the experiences of KC patients on perceived service quality received from public facilities.

RESUMO

Existing evidence indicates that South African university students have low utilisation of Human Immunodeficiency Virus (HIV) Voluntary Counselling and Testing (VCT). A cross-sectional survey was conducted to determine the utilisation of HIV VCT among undergraduate students in the School of Healthcare Sciences. Structured questionnaires were used to collect data through Google Forms. The results are presented through descriptions and percentages and illustrated in tables. Out of 389 undergraduate students, only 324 completed the questionnaire. The majority (97.2%) were aware of the health centre on campus, while only (74.7%) knew about the HIV VCT services offered on campus. Despite the awareness, many (36.7%) do not utilise the campus HIV VCT services, and some (9.6%) have never tested for HIV. There was an association between awareness of Voluntary Counselling and Testing of HIV services offered at the campus health and wellness centre and utilisation of HIV Voluntary Counselling and Testing at (<0.001). Therefore, it is imperative to urgently escalate the level of HIV/AIDS education in higher institutions of learning and emphasise the mounting danger of HIV infection and the immense importance of regular HIV testing. The findings of this study could serve as a foundation for creating HIV prevention and control programmes for youth, particularly in higher education institutions.

RESUMO

BACKGROUND: Hospital pharmacists are important in antibiotic stewardship programs (ASP), a global strategy to combat antibiotic resistance (ABR). South African public hospitals have limited ASP implementation. This study describes Limpopo Provincial Hospital pharmacists' knowledge, attitudes, and practice toward ASP implementation. METHOD: A questionnaire to explore pharmacists' knowledge, attitudes and practices regarding ASP implementation comprised 43 questions hosted online. A link was sent by invitation e-mail to eligible respondents in November 2021. Five questions on respondents' demographics, 15 questions on ASP knowledge, 10 Likert scale questions on attitude, and 13 on ASP practices were included. Mean (standard deviation (SD)) knowledge and attitude scores and a median (interquartile range (IQR)) practice score was calculated. Associations between categorical variables were assessed using chi-square/Fisher's exact analysis (p < 0.05), with Cramér's V as effect size. RESULTS: The survey yielded 35 responses (13.1%). Twenty (57.1%) respondents were female. Seventeen (48.6%) respondents were between the ages of 31 and 40 years. The mean knowledge score of respondents was 9.8 (2.6) (N = 34), with knowledge gaps on One Health and socioeconomic determinates of ABR. Ten (29.6%) respondents thought One Health discouraged multi-sector collaboration, and nineteen (55.9%) respondents thought ASP was the only strategic response to ABR. Sixteen (47.1%) respondents did not know that poor access to clean water accelerates ABR and seventeen (50.0%) did not know that poverty could be a determinant for antibiotic use. The mean respondent attitude score was 8.0 (1.7) (N = 28). Twenty-seven (96.4%) respondents agreed that ASP was necessary and agreed to participate in ASP respectively. All 28 (100.0%) respondents agreed to lead an ASP. The median (IQR) respondents' practice score was - 2.0 (IQR: -6.0-5.8) (N = 16). Respondents were inconsistently (never, sometimes, every time) participating in multi-disciplinary forums (6/16, 37.5%) and expressed a desire for training (11/13, 84.6%) on ASP through in-service (7/27, 25.9%). Respondents thought ASP training should include medical officers (12/29, 41.4%) and nurses (9/29, 31.8%). Knowledge score was associated with gender (p = 0.048; V = 0.416) and attitude score (p = 0.013; V = 0.556). CONCLUSION: Our study found pharmacists had good knowledge and a positive attitude toward ASP implementation but poor ASP practices. A multi-disciplinary in-service training could address identified knowledge and practice gaps.

RESUMO

Sexually transmitted infections in South Africa are increasing at alarming rates. This study's setting is no. 5, with the highest STI, pregnancy, and HIV statistics in Limpopo province among 13- to 19-year-old teenagers. This study explored preventative measures against STIs practiced by teenagers in rural areas of Limpopo province, South Africa. This study was conducted at a selected rural-based clinic using an exploratory descriptive qualitative research approach. Unstructured in-depth face-to-face interviews were used to collect data from sixteen conveniently sampled teenagers aged 13-19, consisting of 13 females and 3 males, who came to Manavhela Clinic for youth-friendly services in August/September 2022. Open-coding analysis was used to identify themes and sub-themes. Measures to ensure trustworthiness were ensured. Ethical clearance (FSH/21/PH/22/2211) was obtained, and ethics principles were observed throughout this study. Two themes emerged from data analysis: STI preventive measures practiced by teenagers and factors influencing the choice of STI preventive measures practiced by teenagers. Only a few participants aged 13 and 14 years of age practiced abstinence and condom use. Most participants were sexually active and used mythical mixtures made from boiling aloe or morula tree (which they drank before and after sex), applied plain yogurt on the vagina once a week, or practiced vaginal steaming. Participants cited patriarchy, lack of sex education in rural schools, long distances to clinics, and desire to taste sex as reasons for adopting the practiced preventive measures. Risky sexual behavior among 13- to 19-year-old teenagers is still rife in rural areas. Rural clinics in Limpopo province should intensify STI school health education and youth-friendly services programs to raise awareness and improve accessibility to condoms.

RESUMO

BACKGROUND: The purpose of this study was to assess the presence of occupational burnout among full-time employed doctors of all ranks at the Mankweng and Pietersburg tertiary academic hospitals in South Africa's Limpopo province. METHODS: A quantitative, observational study was conducted firstly to determine whether burnout was present among medical doctors at these institutions and, secondly, to quantify the amount of burnout in those affected. Data collection was done using structured questionnaires. All ranks of medical doctors from various departments participated in the study, resulting in a total sample size of 150. RESULTS: The study revealed that occupational burnout was present at these institutions, with an overall prevalence of 36%. When compared to other studies conducted at public sector hospitals in South Africa, this figure appears to fall within the middle range. However, different studies have used different criteria to measure burnout. CONCLUSION: Currently, there is too much variation in the criteria of burnout among different studies, making comparisons difficult. More studies are needed to standardise the measurement of burnout.Contribution: The main contribution of the research is to understand the extent of burnout at the tertiary hospital in Limpopo province.

RESUMO

BACKGROUND: Electronic continuous surveillance databases are ideal for monitoring antibiotic use (ABU) in hospitalised patients for antibiotic stewardship programmes (ASP). However, such databases are scarce in low-resource settings. Point prevalence surveys (PPS) are viable alternatives. This report describes ABU and identifies ASP implementation improvement areas in Limpopo Province, South Africa. METHODS: This cross-sectional descriptive study extracted patient-level ABU data from patients' files using a modified global PPS tool. Data were collected between September and November 2021 at five regional hospitals in Limpopo Province, South Africa. All patients in the wards before 8 a.m. on study days with an antibiotic prescription were included. Antibiotic use was stratified by Anatomic Therapeutic Chemical and Access, Watch, Reserve classifications and presented as frequencies and proportions with 95% confidence intervals (CI). Associations between categorical variables were assessed using the chi-square test. Cramér's V was used to assess the strength of these associations. RESULTS: Of 804 inpatients surveyed, 261 (32.5%) (95% CI 29.2-35.7) were prescribed 416 antibiotics, 137 were female (52.5%) and 198 adults (75.9%). One hundred and twenty-two (46.7%) patients received one antibiotic, 47.5% (124/261) received two, and 5.7% (15/261) received three or more antibiotics. The intensive care units had a higher ABU (68.6%, 35/51) compared to medical (31.3%, 120/384) and surgical (28.5%, 105/369) wards (p = 0.005, Cramér's V = 0.2). Lower respiratory tract infection (27.4%, 104/379), skin and soft tissue infections (SST) (23.5%, 89/379), and obstetrics and gynaecology prophylaxis (14.0%, 53/379) were the common diagnoses for antibiotic prescriptions. The three most prescribed antibiotic classes were imidazoles (21.9%, 91/416), third-generation cephalosporins (20.7%, 86/416) and combination penicillin (18.5%, 79/416). Access antibiotics accounted for 70.2% (292/416) of prescriptions and Watch antibiotics for 29.6% (123/416) (p = 0.110, Cramér's V = 0.1). Reasons for prescribing and treatment plans were documented in 64.9% (270/416) (95% CI 60.3-69.5) and 21.4% (89/416) (95% CI 17.3-25.3) of prescriptions, respectively. CONCLUSIONS: The study serves as a baseline for ABU surveillance at the five regional hospitals in Limpopo Province. Lack of documentation indicates poor prescribing practices; ASP should address gaps by deploying evidence-based, multifaceted and stepwise interventions.

RESUMO

Although both short- and long-term psychological challenges, specifically depression and anxiety, have been reported among orphans, there is a dearth of studies that quantify these disorders in rural settings. The aim of the study was to screen for symptoms of depression, anxiety and their co-occurrence among orphaned school-going children in rural Limpopo province, South Africa. Data were collected among primary school children in 10 schools in two villages in Limpopo province. The Revised Child Anxiety and Depression Scale (RCADS) was used to screen for symptoms of depression, anxiety and their co-occurrence among 308 orphaned learners in the selected schools. A questionnaire was used to collect socio-demographic data. STATA 13 was used to analyse the data. Descriptive statistics were used to determine the symptoms and severity of depression, anxiety and their co-occurrence. The sample of 308 consisted of the majority (60.71%) residing in Maandagshoek and being female (54.22%). Their ages ranged from 8 to 12 years, with a mean of 10.51 years. The prevalence of symptoms of depression, anxiety and co-occurrence of anxiety and depression were 23.05%, 34.09% and 32.14%, respectively. The prevalence of mental health symptoms was high among the sample. There is a need to expand the care of orphans to include mental health and not just limit their care to provide food to vulnerable children.

RESUMO

BACKGROUND: Over the past decade, implementation of multiple malaria control strategies in most countries has largely contributed to advance the global malaria elimination agenda. Nevertheless, in some regions, seasonal epidemics may adversely affect the health of local populations. In South Africa, Plasmodium falciparum malaria is still present, with the Vhembe District experiencing an incidence rate of 3.79 cases/1000 person-years in 2018, particularly in the Limpopo River Valley, bordering Zimbabwe. To elucidate the complexity of the mechanisms involved in local regular malaria outbreaks, a community-based survey was implemented in 2020 that focused on the relationship between housing conditions and malaria risky behaviours. METHODS: The community-based cross-sectional survey was conducted among the population of three study sites in the Vhembe District, which were selected based on malaria incidence rate, social and health characteristics of inhabitants. The household survey used a random sampling strategy, where data were collected through face-to-face questionnaires and field notes; to described the housing conditions (housing questionnaire), and focus on individual behaviours of household members. Statistical analyses were performed combining hierarchical classifications and logistic regressions. RESULTS: In this study, 398 households were described, covering a population of 1681 inhabitants of all ages, and 439 adults who participated in community-based survey. The analysis of situations at risk of malaria showed that the influence of contextual factors, particularly those defined by the type of habitat, was significant. Housing conditions and poor living environments were factors of malaria exposure and history, regardless of site of investigation, individual preventive behaviours and personal characteristics of inhabitants. Multivariate models showed that, considering all personal characteristics or behaviours of inhabitants, housing conditions such as overcrowding pressures were significantly associated with individual malaria risk. CONCLUSIONS: The results showed the overwhelming weight of social and contextual factors on risk situations. Considering the Fundamental Causes Theory, malaria control policies based on health behaviour prevention, should reinforce access to care or promoting health education actions. Overarching economic development interventions in targeted geographical areas and populations have to be implemented, so that malaria control and elimination strategies can be efficiently and effectively managed.

RESUMO

Inadequate knowledge and poor attitudes about prostate cancer (PC) negatively affect early screening practices among males. The PC mortality rate is increasing due to late reporting, screening, and treatment. This study explored the awareness, attitudes, and PC screening behaviours among males in the Limpopo, Thulamela municipality. This descriptive cross-sectional study involved 245 males that were randomly selected. A structured questionnaire was used to collect data. Fisher's exact tests and logistic regression analysis were used to examine the association between sociodemographic variables, awareness, and attitudes towards PC. Our findings revealed that 64.1% demonstrated inadequate awareness about PC. The overall score (84.9%) showed a positive attitude towards PC. However, 87.4% had a negative attitude towards the effectiveness of treatment for PC. The majority (96.7%) of respondents had never undergone a PSA test, although 53.1% were willing to undergo a PSA test. There was a significant positive correlation between awareness of prostate cancer and attitudes toward prostate cancer (r = 0.280, p < 0.001). Health status predicted awareness about PC, while age and health status predicted attitudes towards PC among men. Rural community-based programmes and heightened awareness campaigns are needed to conscientize men about the risk factors, symptoms, diagnosis, and treatment of PC in rural areas of Limpopo.

RESUMO

Background: Pregnancy anaemia is a significant public health concern in South Africa (SA), particularly in rural areas, but little is known about its prevalence and risk factors in rural areas. The objective of the study was to determine the prevalence and identify risk factors of pregnancy anaemia in the public health facilities of Limpopo Province (LP), SA. Methods: A cross-sectional study was conducted among a consecutive sample of 211 pregnant women attending antenatal care at Seshego Hospital and its feeder health centre (May to June 2019). Anaemia was defined as haemoglobin (Hb) <11 g/dL and classified as mild (10-10.9 g/dL), moderate (7-9.9 g/dL) and severe anaemia (<7 g/dL). A multiple logistic regression analysis was used to identify predictors of anaemia. Results: The mean age of the women was 28.4 ± 5.7 years (range from 18 to 41 years). Over half (52%) had secondary education, 65% were unmarried, 72% were unemployed, 34% were nulliparous, 15% were human immunodeficiency virus (HIV) infected and 67% were in the third trimester. The anaemia prevalence was 18.0% and was significantly associated with parity, HIV status and body mass index (BMI) in a multivariate logistic regression analysis. Conclusion: This study found that less than one-third of pregnant women were affected by anaemia, associated with parity, HIV infected and BMI. It is essential to promote routine screening for anaemia, health education and prompt treatment of infections to reduce this burden. In addition, further studies on risk factors for anaemia during pregnancy in both urban and rural communities should be conducted to strengthen these findings.

RESUMO

BACKGROUND: Keratoconus (KC) has been regarded as a rare condition, although recent studies, including those in South Africa, suggest it is common and is increasing in prevalence. Furthermore, South African-based studies have shown that KC is normally detected at advanced or severe stages. Knowledge and skills for examination, diagnosis and management of KC by optometrists are important for the early detection and management of the disease. AIM: This study aimed to evaluate self-reported knowledge and skills for examination, diagnosis and management of KC patients among public sector optometrists. SETTING: Seven public hospitals of the Capricorn district of the Limpopo province, South Africa. METHODS: A quantitative cross-sectional descriptive study design was used. A self-administered online questionnaire was used to collect data on demographic characteristics of participants and their knowledge, skills and practice for the diagnosis and management of KC. RESULTS: Twenty-four optometrists (n = 24) with a mean age of 39 ± 5.67 years, 18 (75%) of whom were female, participated in the study. Nineteen (79%) reported that their hospitals did not have the appropriate equipment to examine, diagnose and manage KC patients. Lack of equipment, poor knowledge, skills and competencies, hospital's level of services, policy and lack of interest were cited as barriers to contact lens fittings in KC patients. Using a dichotomised summation of self-reported knowledge and skills of KC, 13 (54.2%) of the optometrists were knowledgeable and skilled on risk factors of KC and examining, diagnosing and managing KC patients. CONCLUSION: A significant proportion of optometrists did not have the appropriate knowledge and skills to examine, diagnose and manage KC patients. Lack of equipment and poor knowledge and skills were the main barriers to contact lens fittings in managing KC.Contribution: This article highlights the need for the district to upskill the optometrists through a structured programme with a theory and practical component and also provide the necessary equipment to enhance patient care.

RESUMO

Background: The World Health Organization (WHO) classified antibiotics into three categories in 2017 - Access, Watch and Reserve (AWaRe) - intending to reduce the consumption of Watch and Reserve antibiotics while increasing the use of Access antibiotics. Antibiotic consumption by AWaRe in South Africa is undetermined because of data and research scarcity. Objectives: The aim of this study was to quantify, describe and track antibiotic consumption between 2014 and 2018 in the public sector of the Limpopo province, South Africa, using the WHO's AWaRe classification for 2021. Method: Antibiotic consumption was quantified from pharmaceutical sales data for 2014-2018 by defined daily dose (DDD) per 1000 inhabitants per day (DID) and described according to the AWaRe classification. The change in antibiotic consumption was measured by compound annual growth rate (CAGR), Access-to-Watch index (AW-I), 75% drug utilisation index (DU75%) and amoxicillin index (AI). Results: The absolute consumption of Access antibiotics decreased by a 4.0% CAGR from 3.7 DID in 2014 to 3.0 DID in 2018, with relative consumption remaining above 80.0%. Relative consumption of Watch antibiotics increased by 15.8% CAGR from 7.8% in 2014 to 19.7% by 2018. The AW-I decreased from 10.4 in 2015 to 4.1 in 2018. The AI increased from 17.8% in 2015 to 42.0% in 2018. Parenteral formulations' DU75% comprised one Watch (ceftriaxone) and two Access (metronidazole and benzylpenicillin) antibiotics. Conclusion: In Limpopo province's public sector, the consumption of Watch antibiotics increased, while Access antibiotics consumption decreased, as reflected by both relative consumption and the decrease in the AW-I. The determinants of the Watch antibiotics increase require research attention. Contribution: Our study addressed the paucity of surveillance and research data on antibiotic consumption in the Limpopo province, South Africa, according to the WHO AWaRe classification.

RESUMO

Background: Antibiotic consumption (ABC) surveillance is a critical component of the strategic priority response to the increasing antibiotic resistance threat. Levels of ABC at the national and provincial levels in South Africa are unknown because of inadequate ABC surveillance systems and literature. Antibiotic consumption in the public sector of Limpopo province, South Africa, 2014-2018. Methods: This retrospective study used sales data retrieved from a pharmaceutical warehouse distribution database to quantify ABC. Antibiotic consumption was measured by the defined daily dose (DDD) per 1000 inhabitants per day (DID) and 75% drug utilisation index (DU75%). Change in consumption was measured by the compound annual growth rate (CAGR). Results: Between 2014 and 2018, the mean ABC was 4.6 ± 1.0 DID, with an overall decrease of 1.6% in the CAGR. Penicillins (2.3 ± 0.8; 50.0%), sulphonamide and trimethoprim combinations (1.4 ± 0.3 DID; 30.4%) were the most consumed antibiotics. Macrolides had the highest relative increase in consumption during the study period, with a CAGR of 18.5%. In contrast, tetracyclines had the highest relative decrease in consumption, with a CAGR of 100.0%. The CAGR ratio for broad- to narrow-spectrum increased by 39.3%, from 0.4 in 2014 to 2.1 in 2018. The DU75% comprised amoxicillin (28.4%), sulphamethoxazole and trimethoprim (SMX-TMP) (27.2%), doxycycline (12.3%) and azithromycin (9.2%). Conclusion: While ABC remained relatively stable throughout the study, there was an increase in broad-spectrum ABC that requires further investigation. Contribution: This study contributes ABC surveillance data in Southern Africa, described by ATC classification, which is essential for monitoring and evaluating antibiotic stewardship programmes.

RESUMO

Rabies is considered a neglected disease among many developing Asian and African countries, including Mozambique, where its re-emergence is often attributed to low dog parenteral vaccination coverage. The objectives of this study were two-fold: (1) to assess the level of antibodies against rabies virus in dogs (n = 418) in Limpopo National Park (LNP), and (2) to genetically characterise selected rabies viruses from brain tissue samples collected in 2017 and 2018. To meet the first objective, we used the BioProTM Rabies blocking ELISA antibody kit, and the results were expressed as the percentage of blocking (%PB). Dog sera with PB ≥ 40% were considered positive for antibodies to rabies virus, whereas sera with PB < 40% were negative. Just under ninety percent (89.2%; n = 373) of dogs were seronegative, and the rest (10.8%; n = 45) had detectable levels of rabies virus-specific antibodies. All eight brain tissue samples were positive for rabies virus antigen using a direct fluorescent antibody test and amplified in a quantitative real-time PCR, but only five (n = 4 from dogs and n = 1 from a cat) were amplified in a conventional reverse-transcription PCR targeting partial regions of the nucleoprotein (N) and the glycoprotein (G) genes. All samples were successfully sequenced. Phylogenetically, the rabies viruses were all of dog origin and were very closely related to each other (Africa 1b rabies virus lineage). Furthermore, the sequences had a common progenitor with other rabies viruses from southern Africa, confirming the transboundary nature of rabies and the pivotal role of dogs in maintaining rabies cycles. The study demonstrates the principal application of the BioProTM rabies ELISA antibody for the detection of anti-lyssavirus-specific antibodies in the serum samples of dogs, and most importantly, it highlights the low levels of antibodies against rabies virus in this dog population.

RESUMO

Background: Disability, and everything it encompasses, presents major challenges to individuals, families and communities worldwide. Children with disabilities (CWD) are marginalised and excluded in most societies. Discrimination and prejudice towards CWD are compounded by poverty, lack of essential services and support and sometimes a hostile and inaccessible environment. Objectives: The study sought to examine the psychosocial challenges experienced by CWD in the Sekhukhune district of Limpopo province, South Africa. Based on the identified, articulated and expressed challenges, the study sought to recommend improvement of the existing Integrated National Disability Strategy (INDS) for greater responsiveness to the needs of CWD at both provincial and local levels. Method: The interpretivist qualitative mode of enquiry was the chosen methodology for this study. Phenomenology and descriptive research designs guided the study. Purposive sampling was employed, and data were collected from 36 participants using three triangulated methods: individual in-depth interviews, focus group discussions and key informant interviews. Thematic data analysis was used to analyse data. Results: The findings revealed that CWD in Sekhukhune experienced numerous challenges which affected their social functioning, development and general well-being. Aggravating factors included stigma, labelling and discrimination; disability-specific discrimination and bullying; exclusive education; sexual exploitation; lack of governmental support and poor implementation of disability-specific policies, amongst others. Conclusion: The provisions of the INDS to promote inclusion, integration, mainstreaming and equitable access to resources and services remained an ideal rather than a reality for CWD in Sekhukhune.

RESUMO

The most important determinants of indigenous health promotion are availability and accessibility of water, food and traditional medicine. It is for this reason that the 1986 Ottawa Charter for Health Promotion proposed the inclusion of food, water and ecosystems in any health promotion strategies. The present study describes the extent to which climate change in the form of rainfall scarcity and increased temperatures impacts the availability and accessibility of quality water, food and traditional medicine as basic determinants of indigenous health promotion. In-depth interviews were conducted with 240 participants purposely selected from Dikgale community in Limpopo Province, South Africa. The study results show that availability and accessibility of water, food and traditional medicine are negatively impacted by increased temperature and scarcity of rainfall. These resources are scarcely encountered, and where they exist, they are of poor quality. However, community members resorted to modern technological practices such as sourcing water from the municipal water reticulation system, buying foodstuffs from retail outlets and immunization against disease via modern health care facilities. It can be deduced from the study that the prerequisites of indigenous health promotion are climate-sensitive. They become available and accessible under favourable climate conditions, and are scarce under unfavourable climate conditions, a situation that compromises the practice of indigenous health promotion.

RESUMO

Although significant scientific research strides have been made in mapping the spatial extents and ecohydrological dynamics of wetlands in semi-arid environments, the focus on small wetlands remains a challenge. This is due to the sensing characteristics of remote sensing platforms and lack of robust data processing techniques. Advancements in data analytic tools, such as the introduction of Google Earth Engine (GEE) platform provides unique opportunities for improved assessment of small and scattered wetlands. This study thus assessed the capabilities of GEE cloud-computing platform in characterising small seasonal flooded wetlands, using the new generation Sentinel 2 data from 2016 to 2020. Specifically, the study assessed the spectral separability of different land cover classes for two different wetlands detected, using Sentinel-2 multi-year composite water and vegetation indices and to identify the most suitable GEE machine learning algorithm for accurately detecting and mapping semi-arid seasonal wetlands. This was achieved using the object based Random Forest (RF), Support Vector Machine (SVM), Classification and Regression Tree (CART) and Naïve Bayes (NB) advanced algorithms in GEE. The results demonstrated the capabilities of using the GEE platform to characterize wetlands with acceptable accuracy. All algorithms showed superiority, in mapping the two wetlands except for the NB method, which had lowest overall classification accuracy. These findings underscore the relevance of the GEE platform, Sentinel-2 data and advanced algorithms in characterizing small and seasonal semi-arid wetlands.
