Utilisation of standardised outcomes measures by clinical Physiotherapists working in Namibia: a nationwide cross-sectional study.

Introduction: The utilisation of standardised outcome measures (SOMs) is crucial for evaluating patients' health status. Physiotherapists are highly recommended to use SOMs routinely. Despite the well-documented benefits of using SOMs, the utilisation of SOMs in clinical practice is still problematic particularly in Africa. In Namibia, there is dearth of information about SOMs utilisation by physiotherapists and the associated factors. This study was aimed at determining the extent of routine utilisation of SOMs and the associated demographic and work-related factors among physiotherapists. Methods: A cross-sectional, nationwide, online survey was conducted and all registered qualified physiotherapists and intern physiotherapists working in public or private hospitals/clinics were invited to participate. Data was analysed using Statistical Package for the Social Sciences (SPSS) version 29.0. The Chi-square (χ2) and Fishers exact test investigated the relationship between the associated factors and routine SOMs utilisation. The alpha level was set at 0.05. Results: Of 230 participants who received the invitational link, 99 (43.0%) responded timeously to the call to participate. Although 97.9% (n=94) of the participants indicated having used at least one type of SOMs in the last six months, the frequency of utilisation varied. Routine utilisation, defined as 70%-100% of the time, was reported in only 49.0% of the participants. The Chi-square test only showed significant findings for gender (p=0.01) and clinical specialty (p=0.004). The odds of utilising SOMs were 4.13 greater among physiotherapists with a clinical specialty and 3.88 times greater for females than males. Conclusion: The rates for routine utilisation of SOMs by Namibian physiotherapists are unfavourable. Female gender and clinical specialty influenced the utilisation of SOMs in daily clinical practice. Cognisant of the study limitations, these results call for the need to improve the routine utilisation of the SOMs in Namibia.

Measuring HIV outcomes for adolescent girls and young women programs in Africa: Using the polling booth survey technique.

INTRODUCTION: Adolescent girls and young women (AGYW) remain highly vulnerable to the risk of acquiring HIV (Human immunodeficiency virus). This study was conducted to measure behavioral, biomedical and structural outcomes for the Global Fund funded AGYW programmes in five African countries with high burden of HIV including Botswana, Cameroon. Lesotho, Malawi and Namibia. METHODS: The study used a mixed methods approach to collect behavioral, structural and biomedical outcome data. Quantitative data were collected through 418 Polling Booth Survey (PBS) sessions from 4,581 AGYWs. Participants were recruited through a community-based multistage sampling technique using sampling weights for urban and rural communities. 23 Focus Group Discussions (FGD) were conducted to understand barriers to use of HIV prevention programme and community recommendations for improved coverage. Ethical approvals were obtained from the ethics review board in all five countries. RESULTS: More than 50% of the respondents from all five countries reported to be sexually active, and at least 30% or more of those who were sexually active had multiple sex partners. There were wide variations between the countries in condom use with a non-marital sexual partner which ranged between 66% in Namibia to 42% in Cameroon. Cameroon (44%) had high percentage of AGYWs with independent income source while school drop-outs were higher in Malawi (55.5%) and Lesotho (46.6%). Nearly 1/4th of AGYWs in all countries, except Namibia, reported experiencing intimate partner violence. Nineteen percent of the respondents were pregnant in the last 12 months, and 50% of those pregnancies were unplanned. Lesotho had the highest proportion of AGYW (90.5%) ever tested for HIV, followed by Malawi (87.5%), Botswana (75%), Cameroon (69%) and Namibia (62.6%). DISCUSSION: There is diversity across the countries, with country-wise and age-wise variations in results. In all countries, the AGYW programme will benefit from a more targeted approach to reach out to the most vulnerable AGYW, strengthening structural interventions, strengthening linkage to PrEP (Pre-Exposure Prophylaxis) and ART (Antiretroviral Therapy) for those who are living with HIV and a strong linkage with reproductive health services. The assessment helped countries to understand the gaps and opportunities to improve the HIV prevention programme with AGYW.

Giant stem tetrapod was apex predator in Gondwanan late Palaeozoic ice age.

Current hypotheses of early tetrapod evolution posit close ecological and biogeographic ties to the extensive coal-producing wetlands of the Carboniferous palaeoequator with rapid replacement of archaic tetrapod groups by relatives of modern amniotes and lissamphibians in the late Carboniferous (about 307 million years ago). These hypotheses draw on a tetrapod fossil record that is almost entirely restricted to palaeoequatorial Pangea (Laurussia)1,2. Here we describe a new giant stem tetrapod, Gaiasia jennyae, from high-palaeolatitude (about 55° S) early Permian-aged (about 280 million years ago) deposits in Namibia that challenges this scenario. Gaiasia is represented by several large, semi-articulated skeletons characterized by a weakly ossified skull with a loosely articulated palate dominated by a broad diamond-shaped parasphenoid, a posteriorly projecting occiput, and enlarged, interlocking dentary and coronoid fangs. Phylogenetic analysis resolves Gaiasia within the tetrapod stem group as the sister taxon of the Carboniferous Colosteidae from Euramerica. Gaiasia is larger than all previously described digited stem tetrapods and provides evidence that continental tetrapods were well established in the cold-temperate latitudes of Gondwana during the final phases of the Carboniferous-Permian deglaciation. This points to a more global distribution of continental tetrapods during the Carboniferous-Permian transition and indicates that previous hypotheses of global tetrapod faunal turnover and dispersal at this time2,3 must be reconsidered.

Perceived competence and related factors affecting the development of the clinical competence of nursing students at two university sites in Namibia: a cross-sectional study.

BACKGROUND: Ensuring that nursing students graduate with the required clinical competence in nursing is a global challenge. To address this challenge, several studies have looked at various aspects of competency and competency development, however there is scanty evidence on factors affecting development of clinical competency in nursing students. Therefore the, purpose of this study was to investigate nurses' perceived competence and related factors affecting the development of clinical competence of nursing students at two university sites in Namibia. METHODS: A cross-sectional design was utilised. Simple random sampling was applied and 272 nursing students at two university campuses in Namibia were selected. An online questionnaire was used. Data were collected between April and May, 2022, over a period of six weeks, and were analysed using Statistical Package of Social Sciences (SPSS) version 27. Chi-square and Spearman correlations were used to assess the associations and correlations, respectively, among the variables. Logistic regression was used to assess the factors associated with the development of clinical competence using a p-value < 0.05 confidence interval. RESULTS: Forty-seven percent (47%) of the students were found to be competent while more than half (53%) were not. A Chi-square test found a statistically significant difference between students studying at different campuses and between different year levels (p = < .05). A regression analysis showed that nursing educators' competence (ß = .128; p = .36) had a positive influence on nursing students' competence levels, unlike the mode of learning (ß = -.140; p = .013), which negatively predicted the development of clinical competence. No significant relationship was found between the development of clinical competence and teaching approaches, assessment, feedback, constructive alignment, theory-practice gap and reflective practice (p = ˃.05). CONCLUSION: Educator's competence levels and the mode of learning were the two major factors that were more likely to influence the development of clinical competence among nursing students. Therefore, it is recommended that nursing training institutions prioritise the development of educators' competence and apply various modes of learning to enhance development of nursing students' competence.

The use of vocal coordination in male African elephant group departures: evidence of active leadership and consensus.

Group-living animals engage in coordinated vocalizations to depart from a location as a group, and often, to come to a consensus about the direction of movement. Here, we document for the first time, the use of coordinated vocalizations, the "let's go" rumble, in wild male African elephant group departures from a waterhole. We recorded vocalizations and collected behavioral data as known individuals engaged in these vocal bouts during June-July field seasons in 2005, 2007, 2011, and 2017 at Mushara waterhole within Etosha National Park, Namibia. During departure events, we documented which individuals were involved in the calls, the signature structure of each individual's calls, as well as the ordering of callers, the social status of the callers, and those who initiated departure. The "let's go" rumble was previously described in tight-knit family groups to keep the family together during coordinated departures. Male elephants are described as living in loose social groups, making this finding particularly striking. We found that this vocal coordination occurs in groups of closely associated, highly bonded individuals and rarely occurs between looser associates. The three individuals most likely to initiate the "let's go" rumble bouts were all highly socially integrated, and one of these individuals was also the most dominant overall. This finding suggests that more socially integrated individuals might be more likely to initiate, or lead, a close group of associates in the context of leaving the waterhole, just as a high-ranking female would do in a family group. The fact that many individuals were involved in the vocal bouts, and that departure periods could be shorter, longer, or the same amount of time as pre-departure periods, all suggest that there is consensus with regard to the act of leaving, even though the event was triggered by a lead individual.

Blood transcriptomic signatures for symptomatic tuberculosis in an African multicohort study.

BACKGROUND: Multiple host blood transcriptional signatures have been developed as non-sputum triage tests for tuberculosis (TB). We aimed to compare the diagnostic performance of 20 blood transcriptomic TB signatures for differentiating between symptomatic patients who have TB versus other respiratory diseases (ORD). METHODS: As part of a nested case-control study, individuals presenting with respiratory symptoms at primary healthcare clinics in Ethiopia, Malawi, Namibia, Uganda, South Africa and The Gambia were enrolled. TB was diagnosed based on clinical, microbiological and radiological findings. Transcriptomic signatures were measured in whole blood using microfluidic real-time quantitative PCR. Diagnostic performance was benchmarked against the World Health Organization Target Product Profile (TPP) for a non-sputum TB triage test. RESULTS: Among 579 participants, 158 had definite, microbiologically confirmed TB, 32 had probable TB, while 389 participants had ORD. Nine signatures differentiated between ORD and TB with equivalent performance (Satproedprai7: area under the curve 0.83 (95% CI 0.79-0.87); Jacobsen3: 0.83 (95% CI 0.79-0.86); Suliman2: 0.82 (95% CI 0.78-0.86); Roe1: 0.82 (95% CI 0.78-0.86); Kaforou22: 0.82 (95% CI 0.78-0.86); Sambarey10: 0.81 (95% CI 0.77-0.85); Duffy9: 0.81 (95% CI 0.76-0.86); Gliddon3: 0.8 (95% CI 0.75-0.85); Suliman4 0.79 (95% CI 0.75-0.84)). Benchmarked against a 90% sensitivity, these signatures achieved specificities between 44% (95% CI 38-49%) and 54% (95% CI 49-59%), not meeting the TPP criteria. Signature scores significantly varied by HIV status and country. In country-specific analyses, several signatures, such as Satproedprai7 and Penn-Nicholson6, met the minimal TPP criteria for a triage test in Ethiopia, Malawi and South Africa. CONCLUSION: No signatures met the TPP criteria in a pooled analysis of all countries, but several signatures met the minimum criteria for a non-sputum TB triage test in some countries.

Strengthening disease surveillance capacity at national level across five countries: a qualitative study.

OBJECTIVES: Disease surveillance is an essential component of public health and a core function of National Public Health Institutes (NPHIs), including to better prepare and respond to infectious diseases outbreaks. Strengthening NPHIs in their efforts to establish and maintain efficient surveillance systems is an opportunity to ensure future outbreak preparedness and response; yet, guidance on how to increase and prioritise capacity building efforts is limited. This study sought to investigate approaches to capacity building and training for disease surveillance at national level and understand the potential role of NPHIs. STUDY DESIGN: Qualitative study. METHODS: This is a qualitative study, based on a literature review and interviews undertaken between June and November 2022. Fifty seven in-depth interviews were conducted in five countries: Côte d'Ivoire, Ecuador, Madagascar, Namibia, and the Kingdom of Saudi Arabia. Participants included a range of professionals from government, NPHIs, academic institutions and the private sector. Interviews were thematically analysed. RESULTS: Selected countries varied in terms of their disease surveillance capacities, as well as in the structure of their surveillance systems and decision-making. Research identified shared priority areas for action at national level, identifying common challenges and opportunities: 1) capacity building, here specifically the need for a training agenda at national level to ensure sustainability and guide donor funded training offers; 2) data tools and technology-to help decision-makers select the best software tool to address countries' identified need; 3) data sharing-the need for clear data sharing standards and norms for national to international data sharing; and 4) genomic sequencing-the need for national genomic surveillance strategies and reporting guidelines. CONCLUSION: Addressing challenges and using opportunities to strengthen disease surveillance at national level is an important step to build capacity in this area and to help prevent future epidemic and pandemics globally. The findings of this study help decision-makers to identify priority areas for capacity building and understand the potential role and significance of NPHIs.

Transforming adolescent menstrual health through policy: the role of value added tax exemptions in improving access to sanitary products.

In Namibia, the Value Added Tax (VAT) Amendment Act 2022, which reclassified the supply of sanitary pads as zero-rated, has significant implications for adolescent girls' menstrual health and education. The policy change responds to the need to address period poverty by making essential menstrual products more accessible and affordable. Menstruation is a normal biological process, and access to sanitary products is a human right. Taxing menstrual products reinforces gender inequalities and raises concerns about the basic rights and dignity of women and girls. The VAT-free policy creates a system to reduce the financial burden on girls and women, making it easier for them to manage their periods safely and with dignity. It has the potential to reduce absenteeism from school, ultimately improving educational outcomes for adolescent girls. However, VAT exemptions alone are insufficient to address the broader accessibility issues that impact menstrual hygiene. Evidence-based policies that focus on the availability and affordability of a full range of sanitary products, in conjunction with regulatory mechanisms for price and quality control, are necessary to ensure that menstrual products are safe, affordable, and accessible for all.

Knowledge, attitudes, practices and risk perception of cattle farmers in Namibia to antibiotic use and resistance.

The misuse of antibiotics in livestock contributes to the emergence of antibiotic resistant bacteria. The development of antibiotic resistance in bacteria of animal origin is of public health concern since drug resistant pathogens in animals can spread to humans. Several countries have therefore introduced regulations to restrict the use of antibiotics in livestock. Namibia was the first African country to ban the use of antibiotics as growth promoters and restrict the use of antibiotics to the treatment of bacterial diseases with a prescription from a veterinarian. However, there are limited studies on antibiotic stewardship among farmers in the country. The aim of this study was to determine the antibiotic awareness and usage of cattle farmers in Oshikoto region Namibia. A questionnaire on antibiotic knowledge, attitudes and practices (KAP) was administered to 274 randomly selected cattle farmers in Namibia. To calculate the KAP scores, one mark was awarded for each correct answer and zero was awarded for incorrect or unsure responses. Respondents having ≥ 50% correct answers were considered as having good KAP scores. The KAP score ranged from 8 to 73%. Forty-three per cent of the respondents had good KAP scores. Good KAP was associated with age, farm type and education status. Semi-commercial/commercial farmers had significantly better KAP than post and homestead farmers. The findings of this study indicate that there is a need to improve antibiotic usage and resistance education programmes in order to promote rational antibiotic usage.

Kinetics and pathways of sub-lithic microbial community (hypolithon) development.

Type I hypolithons are microbial communities dominated by Cyanobacteria. They adhere to the underside of semi-translucent rocks in desert pavements, providing them with a refuge from the harsh abiotic stresses found on the desert soil surface. Despite their crucial role in soil nutrient cycling, our understanding of their growth rates and community development pathways remains limited. This study aimed to quantify the dynamics of hypolithon formation in the pavements of the Namib Desert. We established replicate arrays of sterile rock tiles with varying light transmission in two areas of the Namib Desert, each with different annual precipitation regimes. These were sampled annually over 7 years, and the samples were analysed using eDNA extraction and 16S rRNA gene amplicon sequencing. Our findings revealed that in the zone with higher precipitation, hypolithon formation became evident in semi-translucent rocks 3 years after the arrays were set up. This coincided with a Cyanobacterial 'bloom' in the adherent microbial community in the third year. In contrast, no visible hypolithon formation was observed at the array set up in the hyper-arid zone. This study provides the first quantitative evidence of the kinetics of hypolithon development in hot desert environments, suggesting that development rates are strongly influenced by precipitation regimes.

Experiences of support by unsuppressed adolescents living with HIV and their caregivers in Windhoek, Namibia: a qualitative study.

Background: Adolescents living with HIV (ALHIV) lag behind younger children and adults in the achievement of HIV care and treatment targets for HIV epidemic control. Treatment outcomes for adolescents may be influenced by their experiences with the support provided in HIV programs. We report on the experiences of virally unsuppressed adolescents and their caregivers with the current support in primary healthcare settings in Namibia. Methods: A qualitative descriptive and exploratory study was conducted in 13 public primary healthcare facilities in Windhoek, Namibia. A total of 25 in-depth interviews were conducted with unsuppressed adolescents (n = 14) and their caregivers (n = 11) between August and September 2023. The audio-recorded interviews were transcribed verbatim, and uploaded into ATLAS.ti software, and subjected to thematic content analysis. Findings: Three main support domains for the unsuppressed adolescents emerged from our analysis, namely: psychosocial, clinical and care, and socioeconomic support. The psychosocial support was delivered through peer support (teen clubs and treatment supporters) and enhanced adherence counselling mostly. The clinical and care support included implementing adolescent-friendly HIV services, differentiated service delivery approaches, and caregivers and healthcare worker care support for improved ART adherence, clinic attendance and continuous engagement in care. Socioeconomic support was provided for nutritional support, transport to access clinics, and school supplies, as well as income-generating projects. Conclusion: Psychosocial, clinical and care, and socioeconomic support are key elements in addressing the needs of adolescents challenged with achieving viral suppression. Health systems may benefit from whole-of-society and whole-of-government approaches to meet the needs of ALHIV that are beyond the scope of health service delivery such as nutritional, education and socioeconomic influences on both the health and well-being of ALHIV.

Electronic distance based clinical skills training development in family medicine in Namibia.

Workplace-based evaluation is one of the most important, but challenging aspects of medical education. The aim was to improve the assessment of the rural community-based clinical training for undergraduate 3rd and 4th year family medicine students at the University of Namibia (UNAM) and implement a paperless process. An online module was developed on the Moodle platform to include a study guide, an electronic portfolio, and electronic resources (e-books and apps) to replace the current paper version of the logbook. We explored local resources by engaging with students and clinical trainers on how to best conduct the initial implementation. Engagement also entailed motivating students to actively participate in the implementation process. All 3rd and 4th year community-based education end service (COBES) students are now submitting proof of clinical learning electronically with the use of their phones in their online portfolio and using online resources. In addition, students in the practical family medicine module that has been introduced in the 6th year since 2023 are now also using an electronic portfolio and these assessment tools.Contribution: Overall feedback from students and supervisors indicates a positive atmosphere of learning and constructive feedback on performance from all team members, hopefully improving work-based assessments and ultimately patient care. More members of the primary health care team were involved and the carbon footprint has also been decreased.

Perspectives of pregnant women on the utilisation of a maternity waiting home near Onandjokwe Lutheran Hospital in Oshikoto Region, Namibia.

BACKGROUND:  Despite the efforts of Namibia's Ministry of Health and Social Services to build maternity waiting homes (MWHs), few pregnant women make use of them. Long distances among the general population in Namibia limit the utilisation of MWHs. Little research has investigated what factors are limiting the use of these facilities despite the urgent need for them. The aim of this study thus was to explore and describe the perspectives of pregnant women on the utilisation of the MWHs near Onandjokwe Lutheran Hospital in Oshikoto Region. METHODS:  A qualitative, exploratory, descriptive and contextual design was employed. The accessible population in this study comprised 18 participants who were selected for the study using a purposive sampling technique. RESULTS:  Participants reported numerous barriers to visiting MWHs in Namibia, including an inadequate number of rooms, theft, food scarcity and the effects of poverty on the living conditions of the MWH users. Enablers visiting MWHs included the safe delivery of babies by skilled staff, reduced transport costs, access to timely management of labour complications and affordable accommodation. CONCLUSION:  The study revealed that a number of barriers must be overcome before the desired number of women take advantage of MWHs. Multiple factors act as constraints to their use, including inadequate number of rooms, theft, food scarcity and the long distance between patients' homes and MWH services.Contribution: The study's findings can be used to develop targeted interventions and strategies that can be used by MWH providers to address the identified barriers.

The hidden oases: unveiling trophic dynamics in Namib's fog plant ecosystem.

The Namib Desert is a hyperarid coastal desert where fog is a major moisture source. We hypothesized that the fog-harvesting grass Stipagrostis sabulicola establishes an important ecological niche, termed the "Fog-Plant-Oases" (FPOs), and serves as the primary carbon source for the invertebrate community. To determine this, we measured the natural variations of the stable carbon and nitrogen isotopes (δ13C and δ15N) of invertebrates as well as that of plant biomass and belowground detritus and estimated the contributions of the fog plants in their diets. Our findings revealed a complex trophic structure and demonstrated that S. sabulicola fuels carbon flow from lower to higher trophic levels in the aboveground food web. The distinct δ13C values of bacterial- and fungal-feeding nematodes indicated however the separation of the aboveground niche, which is primarily sustained by S. sabulicola, from the belowground niche, where wind-blown sediments may serve as the main energy source for the soil biota. Our findings further accentuate the critical role of S. sabulicola FPOs in establishing complex trophic dynamics and a distinctive food web within the hyperarid Namib dunes.

Medical mistrust, discrimination and healthcare experiences in a rural Namibian community.

Substantial evidence indicates that medical mistrust, resulting from experiences with discrimination and marginalisation, is a determinant of health disparities in minority populations. However, this research is largely limited to the US and other industrialised countries. To broaden our understanding of the role of medical mistrust on health-care decision making, we conducted a study on healthcare experiences and perceptions in a rural, underserved indigenous community in northwest Namibia (n = 86). Mixing semi-structured interview questions with the medical mistrust index (MMI), we aim to determine the relevance of the MMI in a non-industrialised population and compare index scores with reports of healthcare experiences. We find that medical mistrust is a salient concept in this community, mapping onto negative healthcare experiences and perceptions of discrimination. Reported healthcare experiences indicate that perceived incompetence, maltreatment and discrimination drive mistrust of medical personnel. However, reporting of recent healthcare experiences are generally positive. Our results indicate that the concept of medical mistrust can be usefully applied to communities in the Global South. These populations, like minority communities in the US, translate experiences of discrimination and marginalisation into medical mistrust. Understanding these processes can help address health disparities and aid in effective public health outreach in underserved populations.

Experiences and challenges of enrolled nurses undertaking a Bachelor of Nursing Science programme in Namibia.

BACKGROUND:  Globally, enrolled nurses (ENs) are embarking on an educational journey to become registered nurses (RNs) in order to enhance their knowledge and career opportunities. However, their aspiration is not without challenges. In Namibia, the experiences of these nurses have not been extensively researched. OBJECTIVES:  This study aims to explore and describe the experiences and challenges of ENs undertaking a Bachelor of Nursing Science at the University of Namibia. METHOD:  A qualitative, exploratory, descriptive and contextual research strategy was followed as the basis of conducting the study. A sample of 15 nursing students was purposively selected from the target population of 73 nursing students. This sample size was determined by the saturation of data as reflected in repeating themes. The collected data were analysed thematically using an inductive approach. RESULTS:  Three main themes subsequently emerged from the study: ENs' positive experiences advancing in the Bachelor of Nursing Science (BNSc) programme; nurses' negative experiences advancing in the BNSc programme; and recommendations to ensure effective advancement in the BNSc programmeConclusion: The findings of this study revealed that ENs positively experience becoming a RN when it comes to self-development; however, they have negative experiences such as not receiving exemptions for prior learning and having to learn a new curriculum.Contribution: These findings may be used by the Faculty of Health Sciences, School of Nursing and Public Health management in order to develop targeted interventions and ongoing strategies during their curriculum review cycles to ensure positive student experiences and success within the programme.

Factors affecting the adoption of circular economy in mining companies of developing economies - A Namibian stakeholder perspective.

The factors influencing the adoption and implementation of CE in developing countries are not yet fully examined. By focusing on the Namibian mining sector, this study highlights the perspectives of local stakeholders on CE adoption in a developing country. The mine managers recognized that waste is problematic and that CE practices are beneficial for mining companies and Namibia at large. Our findings also indicated that stronger academic institutions providing CE training and helping develop CE solutions, public awareness campaigns, financial support for CE practices, cooperation among industry stakeholders, and clear CE policy would all help drive the implementation of CE.

Determination of birth prevalence of sickle cell disease using point of care test HemotypeSC™ at Rundu Hospital, Namibia.

BACKGROUND: Sickle cell disease (SCD), a noncommunicable disease, has the greatest burden in sub-Saharan Africa. The majority of children (50-90%) with SCD die before their 5th birthday, with approximately 150,000-300,000 annual SCD child deaths in Africa. In developed countries, newborn screening (NBS) has been shown to improve the survival of children with sickle cell disease, with under5 childhood mortality reduced tenfold due to interventions performed before the development of complications. Point -of-care tests have been developed for resource limited settings to expand NBS. The aim of this study was to determine the birth prevalence of sickle cell disease in Namibia using the HemoTypeSC™ point-of-care test. METHODS: A cross-sectional descriptive study was carried out at Rundu Intermediate Hospital in the Kavango East Region. Two hundred and two (202) well newborns within 72 h of birth were recruited for the study from 22 February to the 23th March 2023. Descriptive statistics were used to compute the haemoglobin types of the study participants. RESULTS: The majority of the participants (n = 105, 52%) were females, and (n = 97,48%) were males. The median age of the participants was 23 h (Q1, Q3; 11; 33),) with an age range of 2-98 h. Sickle cell trait was present in 9.4% of the screened newborns, no homozygous disease was detected, and 90.6% had Hb AA. CONCLUSIONS: This study is the first to measure HbS gene carriage at birth using HemotypeSC point-of-care testing in Namibia. There was a moderate prevalence of sickle cell traits but no SCD. This baseline study may provide the foundation for larger epidemiological surveys to map HbS gene carriage in Namibia to provide evidence for policy makers to fashion appropriate SCD newborn screening services.

DESCRIPTION OF FEMALE DENDRITOBILHARZIA PULVERULENTA (BRAUN, 1901) SKRJABIN, 1924 FROM TWO NEW AVIAN HOSTS IN NAMIBIA WITH PHYLOGENETIC ANALYSES AND COMMENTS ON SEVERAL TAXONOMICALLY UNCERTAIN AVIAN SCHISTOSOME SEQUENCES.

During a 2021 parasitological survey of birds in the Nyae Nyae-Khaudum Dispersal Area (Kavango-Zambezi Transfrontier Conservation Area, Namibia), we collected 9 specimens of Dendritobilharzia pulverulenta (Braun, 1901) Skrjabin, 1924 infecting the blood (heart lumen) of a white-backed duck, Thalassornis leuconotus (Eyton, 1838) (Anseriformes: Anatidae), and a fulvous whistling duck, Dendrocygna bicolor (Vieillot, 1816) (Anatidae). These flukes were fixed for morphology and preserved for DNA extraction. We assigned our specimens to DendritobilharziaSkrjabin and Zakharow, 1920 because they were strongly dorso-ventrally flattened in both sexes and had an intestinal cyclocoel with a zig-zag common cecum with lateral dendritic ramifications, numerous testes posterior to the cyclocoel and flanking the dendritic ramifications, and a tightly compacted convoluted ovary as well as lacking an oral sucker, ventral sucker, and gynaecophoric canal. Further, our specimens were morphologically identical to previously published descriptions of D. pulverulenta. Sequences of the 28S from our specimens were nearly identical to those identified as D. pulverulenta from North America (New Mexico), and our 28S phylogenetic analysis recovered D. pulverulenta within a polytomy of other Gigantobilharziinae spp. The CO1 phylogenetic analysis recovered a monophyletic Dendritobilharzia and, with low taxon sampling, a monophyletic Gigantobilharzia. This is the first record of a species of Dendritobilharzia infecting these ducks as well as the first record of an adult Dendritobilharzia from sub-Saharan Africa. The original description of adult D. pulverulenta (type locality: northern Sudan) was based on 2 males only, and hence the present study is the first description of female D. pulverulenta from Africa (the continent of the type locality). We reassign 2 Gigantobilharziinae spp. based on morphology and nucleotide evidence: Gigantobilharzia ensenadense (Lorenti, Brant, Gilardoni, Diaz, and Cremonte, 2022) Dutton and Bullard, n. comb., and Gigantobilharzia patagonense (Lorenti, Brant, Gilardoni, Diaz, and Cremonte, 2022) Dutton and Bullard, n. comb. We also comment on several avian schistosome sequences whose identities need confirmation or that likely have been misidentified.

Patterns of availability and accuracy of risk factor data for cardiovascular diseases among people initiated on antiretroviral therapy at selected health facilities in Khomas region, Namibia: a retrospective, cross-sectional, quantitative study.

Introduction: quality data is a prerequisite for timely decision-making and measuring health outcomes in public health settings. Comorbidities such as cardiovascular diseases (CVDs) among people living with HIV (PLHIV), require a robust system that ensures credible data at all data-producing levels. The study at determining the level of availability and completeness of CVDs risk factors data of PLHIV. Methods: a quantitative study was conducted to extract CVDs risk factors data retrospectively from 529 patient care booklets (PCBs) between 2004 and 2017. The analysis was done with the Statistical Package for Social Sciences (SPSS) version 25. Pearson Chi-Square was used to test for associations. The level of significance was at p ≤ 0.05. Results: the study revealed that 72.8% of patients are at risk of CVDs due to incomplete demographics (73.72%) and other systemic data (41.18%). A significant association was found (Pearson Chi-Square test 19.907; p-value of 0.001) between average visits per year, accurate data recording, and active status of the patient. Lost to follow-up (15%) and true retention (27.2%) was significantly associated with the last Antiretroviral Therapy (ART) status of a patient (Pearson Chi-Square test 87.754; p-value of 0.001). Conclusion: the study that despite concerted efforts to improve data quality, the availability and completeness of data remain unsatisfactory. Lack of harmonised data screening and analysis efforts for CVDs risk factors is found to be a significant risk factor in ensuring integrated routine measuring of CVDs health outcomes for PLHIV.
