Project description:Despite the impact of oral diseases on the quality of life, there is limited updated evidence on oral health status in Limpopo province.To determine the epidemiological profile of patients utilising public oral health services in Limpopo province.This was a descriptive retrospective clinical chart review conducted in five purposively selected district hospitals in Limpopo province. The collected data included the patient's sociodemographic information, reasons for dental consultation, information on the dental or oral diseases and the treatment received. Five hundred clinical files were systematically selected (100 from each district hospital) for the period 01 January 1995 to 31 December 2013. Data were collected using the World Health Organization's indicator age groups, namely 6-year-olds, 12-year-olds, 18-year-olds and 35-44-year-old groups. A data capturing sheet was used to record the collected information. Data were analysed using the statistical software package for social sciences SPSS version 23.0.The majority of patients were in the age group of 6 to 20 years (n = 375, 75%). The majority were male patients (n = 309; 62%). Dental caries was the most common complaint (n = 298, 60%). The second most common main complaint in this age group was retained primary or deciduous teeth (n = 60, 12%) affecting children mainly in the age group of 6 to 12 years. The most common clinical procedure across all five districts was dental extractions (n = 324, 64%). Other clinical interventions included scaling and polishing (n = 33, 12%) and dental restorative care (n = 20, 3%).There is an urgent need to reorient oral health service delivery in Limpopo province to focus more on preventive oral health programmes.

Project description:Despite the annual implementation of a robust and extensive indoor residual spraying programme against malaria vectors in Limpopo Province (South Africa), significant transmission continues and is a serious impediment to South Africa's malaria elimination objectives. In order to gain a better understanding regarding possible causes of this residual malaria, we conducted a literature review of the historical species composition and abundance of malaria vector mosquitoes in the Limpopo River Valley region of the Vhembe District, northern Limpopo Province, the region with the highest remaining annual malaria cases in South Africa. In addition, mosquito surveys were carried out in the same region between October 2017 and October 2018. A total of 2225 adult mosquitoes were collected using CO2-baited tent and light traps, human landing catches and cow-baited traps. Of the 1443 Anopheles collected, 516 were members of the An. gambiae complex and 511 An. funestus group. In the malaria endemic rural areas outside the Kruger National Park, one specimen each of An. gambiae s.s. and An. funestus and only three of An. arabiensis were collected. The latter species was abundant at a remote hot spring in the neighboring Kruger National Park. Eighteen other species of Anopheles were collected. Our survey results support the historical findings that An. arabiensis, the species widely held to be the prime malaria vector in South Africa, is a rare species in the malaria endemic Limpopo River Valley. The implications of the mosquito surveys for malaria transmission, elimination and vector control in northern Limpopo Province and neighboring regions are discussed.

Project description:Researchers have long studied the causes and prevention strategies of poor household water quality and early childhood diarrhea using intervention-control trials. Although the results of such trails can lead to useful information, they do not capture the complexity of this natural/engineered/social system. We report on the development of an agent-based model (ABM) to study such a system in Limpopo, South Africa. The study is based on four years of field data collection to accurately capture essential elements of the communities and their water contamination chain. An extensive analysis of those elements explored behaviors including water collection and treatment frequency as well as biofilm buildup in water storage containers, source water quality, and water container types. Results indicate that interventions must be optimally implemented in order to see significant reductions in early childhood diarrhea (ECD). Household boiling frequency, source water quality, water container type, and the biofilm layer contribution were deemed to have significant impacts on ECD. Furthermore, concurrently implemented highly effective interventions were shown to reduce diarrhea rates to very low levels even when other, less important practices were suboptimal. This technique can be used by a variety of stakeholders when designing interventions to reduce ECD incidences in similar settings.

Project description:Biogas is a clean and renewable form of energy available to low-income households through anaerobic digestion of readily available organic waste. A biodigester converts fermentable organic matter into a combustible gas and organic manure. Anaerobic digestion is a process of subjecting the material to microbial decomposition in the absence of air, yielding finally, methane, carbon dioxide, and water inside the biodigester. In the recent years, biogas has attracted wide attention in view of the fuel crisis and the environmental pollution associated with the fossil fuel, and its importance as an efficient and non-polluting energy source is now well appreciated. The objectives of this desktop study are to investigate the relevance of biogas technology use for substitution of solid fuels in rural areas of Vhembe district, the subsequent health co-benefits, and the constraints to adoption of domestic biogas technology in South Africa. The correlating factors influencing decisions in the sustainable adoption and utilisation of biogas technology in Vhembe district of Limpopo Province in South Africa are examined. In this study, the sampled households involved 72 biogas users and 128 non-users. The sampling techniques was purposive and simple random. The study was based on primary data that was elicited using open and closed-ended questionnaires. The logistic regression model was employed for data analysis. The energy demand of low-income South African households for cooking with fuelwood was found to be 27 MJ/day and the total energy demand 68 MJ/day. Approximately 625 000 households in Vhembe district can potentially benefit from bio-digester fed with cattle and pig waste, on the basis of livestock numbers. Most governments worldwide are now considering locally accessible, available, and renewable substitute energy options.

Project description:BACKGROUND:In 2015, malaria infected over 212 million people and killed over 429,000 individuals, mostly children under 5 years of age, with 90% of malaria cases occurring in sub-Saharan Africa. The aim was to develop an age and culturally appropriate song for Tshivenda-speaking children under 5 years of age to decrease the risk of malaria in Limpopo Province, South Africa. METHODS:Document review was used to identify appropriate disease determinants to decrease risk in children <?5 years old in the study area. These were used to develop lyrics and music for a song about malaria in line with the principles of participatory risk analysis. The age and cultural appropriateness of the song as well as disease determinants chosen were reviewed using a modified Delphi technique, by 10 purposively selected experts in malaria (4), Vhavenda music (3) and early childhood education (3). Thereafter, the song was translated into Tshivenda and reviewed by two focus groups living in the study area, one including female caregivers and pre-school teachers (n?=?7) and a second comprising of male community based malaria control personnel (n?=?5). RESULTS:The experts surveyed and both focus groups strongly supported the inclusion of knowledge about the link between mosquitoes and malaria and that children should know the signs of malaria to facilitate early diagnosis. Although the expert group felt that bed nets should not be mentioned, both focus groups suggested the inclusion of bed nets and it was observed that community members were purchasing their own nets. Focus group members also felt that young children should not be involved in internal residual spraying initiatives. CONCLUSIONS:It was concluded that although risk communication on malaria prevention and treatment in young children should be aimed at caregivers, an age and culture appropriate song about malaria could be developed to help young children protect themselves. This song focused on understanding the link between mosquitoes and malaria, preventing exposure and recognising signs of disease.

Project description:BACKGROUND:Cervical cancer remains the major public problem worldwide and the most common gynaecological malignancy in the developing world, particularly in sub-Saharan Africa. AIM:To determine the prevalence of abnormal cervical cytology amongst women with and without human immunodeficiency virus (HIV) and examine the association between HIV and histological grading. SETTING:The study was conducted in Limpopo province, which is the northernmost province of South Africa. The province has five district municipalities with one tertiary, five regional and thirty four district hospitals. METHODS:We retrospectively reviewed cervical cancer cases in Limpopo province (LP) of South Africa, using data collected routinely by the National Health Laboratory Services (NHLS). The data on smears submitted for cytology between 2013 and 2015 were extracted from the Central Data Warehouse (CDW) database. RESULTS:A total of 84 466 women were screened for cervical cytology smears. Their mean age was 39.8 ± 13.6 years, with range from 15 to 113 years; 77.2% were in the age group 30 years and older and 19.6% had an abnormal cervical cytology result. Overall, 46.4% of the women screened for cervical cancer were HIV infected. A significantly higher proportion of HIV-positive women had abnormal cytology than HIV-negative women (31.8% vs. 9.2%). CONCLUSION:The prevalence of abnormal cytology amongst HIV-positive women is relatively high, and the risk appears to be significantly greater in all age groups. This finding highlights the need to ascertain HIV status of all women presenting with cervical cancer.

Project description:Colophospermum mopane (J. Kirk ex Benth.) J. Kirk ex J. Léonard occurs over a very large region of southern Africa, occupying varying habitats that could account for ecotypic speciation. This investigation statistical analysed the variations in the architecture of the leaflets of C. mopane from the Limpopo Province of South Africa, with the purpose of ascertaining whether natural variability can act as a source of information for investigating ecotypic variation. Leaf morphometric traits, such as leaflet area, length, width, perimeter, pulvinus angle and the acuteness of the apex, were digitally measured and statistically compared for intra- and inter-population variability. Data indicate that the intra-population variation is 35.33% (statistical similarity: 64.67%), while the inter-population (n = 5) variation is 46.67% (statistical similarity: 53.33%).

Project description:Due to global climate change, droughts are likely to become more frequent and more severe in many regions such as in South Africa. In Limpopo, observed high climate variability and projected future climate change will likely increase future maize production risks. This paper evaluates drought patterns in Limpopo at two representative sites. We studied how drought patterns are projected to change under future climatic conditions as an important step in identifying adaptation measures (e.g., breeding maize ideotypes resilient to future conditions). Thirty-year time horizons were analyzed, considering three emission scenarios and five global climate models. We applied the WOFOST crop model to simulate maize crop growth and yield formation over South Africa's summer season. We considered three different crop emergence dates. Drought indices indicated that mainly in the scenario SSP5-8.5 (2051-2080), Univen and Syferkuil will experience worsened drought conditions (DC) in the future. Maize yield tends to decline and future changes in the emergence date seem to impact yield significantly. A possible alternative is to delay sowing date to November or December to reduce the potential yield losses. The grain filling period tends to decrease in the future, and a decrease in the duration of the growth cycle is very likely. Combinations of changed sowing time with more drought tolerant maize cultivars having a longer post-anthesis phase will likely reduce the potential negative impact of climate change on maize.

Project description:BackgroundHospital 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.MethodA 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.ResultsThe 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).ConclusionOur 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.

Project description:BACKGROUND:Skin-related diseases affect every individual irrespective of age, gender or social status. Since time immemorial, humans have explored natural resources from their environment for the maintenance of the skin. This explorative survey was conducted to document the natural resources (plant and non-plant materials) used for folk cosmeceuticals by rural communities in Vhembe district municipality, Limpopo province, South Africa. METHODS:The research was conducted in six communities namely: Tshakuma, Shigalo, Tshamutilikwa, Luvhimbi (Masikhwa), Khakhanwa, and Folovhodwe in Vhembe district. Random and convenient sampling was used to access the target population. Semi-structured questionnaires were used to interview 71 participants that comprised traditional practitioners, herbalists and laypeople from the study area. Collected data were analysed using both quantitative (for e.g. frequency, use-value and relative frequency of citation) and qualitative (thematic) analytical methods. RESULTS:A total of 52 plants from 27 families and 22 non-plant materials were used as folk cosmeceuticals in the study area. The most cited plants included Dicerocaryum zanguebarium (Pedaliaceae), Ricinus communis (Euphorbiaceae) and Helinus integrifolius (Rhamnaceae). Trees and shrubs were the most common plant-life form while leaves were the most popular plant part. Pig fats, red ochre (Luvhundi soil) and ashes were the most cited non-plant materials. These documented natural resources are frequently prepared by crushing and mostly used to heal wounds. CONCLUSION:Traditional knowledge concerning folk cosmeceuticals is mostly held by elders. The high number of natural resources documented is an indication that Vhembe district is rich in ethnopharmacological knowledge. Scientific investigation of the efficacies and safety of these natural resources is highly recommended as a drive aimed at innovations with benefits to the rural communities who are the custodians of this valuable knowledge.
