Adult surgical admissions at a Botswana tertiary teaching hospital - spectrum, comorbidity profile, and outcomes.

BACKGROUND: Documentation on the spectrum, comorbidities, profile, and outcomes of adult surgical admissions in Botswana is limited. This information may guide manpower distribution for proposed rotations in the new general surgery training programmes. METHODS: The medical records of adult surgical admissions for a period of one year (August 2017 - July 2018) were reviewed retrospectively. Demographics, types of admissions, dates of admission and discharge, and known comorbidities were captured and the outcomes were analysed. RESULTS: Of the 2610 admissions the mean age was 44.4 years and 60.8% were male. Gastrointestinal tract (GIT), neurosurgical, and cardiothoracic admissions constituted 60.7%. Emergency admissions constituted 50.1%. Comorbidities were found in 45.6% of the admissions, and HIV-prevalence was 697/1822 (38.3%) among known HIV-status patients. Elective admissions underwent more surgical procedures, 776/1303 (59.6%), p = 0.001 (COR 1.9, 95% CI:1.7-2.3). A total of 220/2610 complications (8.4%) were documented, including 42/1355 (3.1%) superficial surgical site infections and 159/2610 deaths (6.1%). Hypertension and diabetes mellitus were associated with higher mortality, p = 0.002 (COR 1.8,95% CI:1.2-2.6) and p = 0.031 (COR 1.9, 95% CI:1.1-3.4) respectively. HIV-positive patients had longer hospital stays than HIV-negative patients, p = 0.001 (COR 1.03, 95% CI:1.02-1.04). HIV-positive admissions with CD4 count < 200 had significantly higher composite complication and mortality rate than those with ≥ 200, p = 0.002 (COR 3.03, 95% CI:1.52-6.04) and p = 0.001 (COR 4.34, 95% CI:2.08-9.05) respectively. CONCLUSION: Contributions of emergency and elective admissions were even. A higher burden of diseases was found in gastroenterology. The higher mortalities associated with hypertension, diabetes, and CD4 count < 200 warrant further study.

Caregivers of children with HIV in Botswana prefer monthly IV Broadly Neutralizing Antibodies (bNAbs) to daily oral ART.

INTRODUCTION: Monthly intravenous infusion of broadly neutralizing monoclonal antibodies may be an attractive alternative to daily oral antiretroviral treatment for children living with HIV. However, acceptability among caregivers remains unknown. METHODS: We evaluated monthly infusion of dual bNAbs (VRCO1LS and 10-1074) as a treatment alternative to ART among children participating in the Tatelo Study in Botswana. Eligible children aged 2-5 years received 8-32 weeks of bNAbs overlapping with ART, and up to 24 weeks of bNAbs alone as monthly intravenous infusion. Using closed-ended questionnaires, we evaluated caregiver acceptability of each treatment strategy prior to the first bNAb administration visit (pre-intervention) and after the completion of the final bNAb administration visit (post-intervention). RESULTS: Twenty-five children completed the intervention phase of the study, and acceptability data were available from 24 caregivers at both time points. Responses were provided by the child's mother at both visits (60%), an extended family member at both visits (28%), or a combination of mother and an extended family member (12%). Caregiver acceptance of monthly bNAb infusions was extremely high both pre-and post-intervention, with 21/24 (87.5%) preferring bNAbs to ART pre-intervention, and 21/25 (84%) preferring bNAbs post-intervention. While no caregiver preferred ART pre-intervention, 2/25 preferred it post-intervention. Pre-intervention, 3 (13%) caregivers had no preference between monthly bNAbs or daily ART, and 2 (8%) had no preference post-intervention. Pre-intervention, the most common reasons for preferring bNAbs over ART were the perception that bNAbs were better at suppressing the virus than ART (n = 10) and the fact that infusions were dosed once monthly compared to daily ART (n = 9). Post-intervention, no dominant reason for preferring bNAbs over ART emerged from caregivers. CONCLUSIONS: Monthly intravenous bNAb infusions were highly acceptable to caregivers of children with HIV in Botswana and preferred over standard ART by the majority of caregivers.

Age and healthy lifestyle behavior's disparities and similarities on knowledge of myocardial infarction symptoms and risk factors among public and outpatients in a resource-limited setting, cross-sectional study in greater Gaborone, Botswana.

OBJECTIVES: In this cross-sectional study from Botswana, we investigated knowledge of myocardial infarction (MI) symptoms and risk factors among the general public and outpatients with MI risk factors based on age and lifestyle behaviors, in addition to assessing associations with sociodemographic and MI risk factors. METHOD: Open-ended questionnaires about 8 MI symptoms and 10 risk factors, were administered by research assistants to a representative selection of outpatients (n = 525) and the public (n = 2248). Weight and height were measured in all participants and BMI was calculated. Knowledge scores were compared between the two groups. We examined whether sociodemographic and MI risk factors had impact on the scores. Analyses were further adjusted for lifestyle behavior (smoking status, dietary status and physical activities). RESULTS: The valid response rate was 97.9% comprising 97.8% for the public (n = 2199) and 98.1% for outpatients (n = 515). Public respondents (35.2 ± 12.3 years) were younger than outpatients (38.5 ± 12.6 years). The public comprised 56.9% females while outpatients 54.6%. In general, outpatients had higher knowledge of MI symptoms than the public, with mean scores ± SD of 3.49 ± 2.84 vs 2.80 ± 2.54. Outpatients also had higher knowledge score of MI risk factors than the public, with mean scores, 5.33 ± 3.22 vs 3.82 ± 3.07. For MI symptoms, outpatients were more aware than the public for chest pains among all ages, for arm pain/ numbness, neck/ jaw pain radiating to/ from chest, and feeling sick or looking pallor on the skin among those aged 35-49 years. Among both the public and outpatients, lower knowledge of both MI symptoms and risk factors was associated with primary education, not residing/working together, history of hypertension, no history of heart disease/stroke, and obesity. There were similarities and disparities on MI knowledge among respondents with various numbers of healthy lifestyle behaviours. CONCLUSION: Results call for urgent educational campaigns on awareness and knowledge of MI and using strategies based on age and lifestyle behavior.

Progress towards the UNAIDS 95-95-95 targets in the Fifth Botswana AIDS Impact Survey (BAIS V 2021): a nationally representative survey.

BACKGROUND: In 2014, UNAIDS set a goal to end the AIDS epidemic by achieving targets for the percentage of people living with HIV who were aware of their status, on antiretroviral therapy (ART), and virally suppressed. In 2020, these targets were revised to 95% for each measure (known as 95-95-95), to be reached among people living with HIV by 2025. We used data from the Fifth Botswana AIDS Impact Survey (BAIS V) to measure progress towards these testing and treatment targets in Botswana. METHODS: BAIS V used a two-stage cluster design to obtain a nationally representative sample of people aged 15-64 years in Botswana. During March-August, 2021, 14 763 consenting participants were interviewed and tested for HIV in their households by survey teams. HIV-positive specimens were tested for viral load, presence of antiretroviral drugs, and recency of infection using the HIV-1 limiting antigen avidity enzyme immunoassay. Estimates of HIV-positive status and use of ART were based on self-report and the analysis of blood specimens for antiretroviral drugs. Viral load suppression was defined as an HIV RNA concentration of less than 1000 copies per mL. HIV incidence was calculated using the recent infection testing algorithm. Data were weighted to account for the complex survey design. FINDINGS: The national HIV prevalence in Botswana among people aged 15-64 years was 20·8% and the annual incidence of HIV infection was 0·2%. 95·1% (men 93·0%, women 96·4%) of people living with HIV aged 15-64 years were aware of their status, 98·0% (men 97·2%, women 98·4%) of those aware were on ART, and 97·9% (men 96·6%, women 98·6%) of those on ART had viral load suppression. Among young people (aged 15-24 years) living with HIV, 84·5% were aware of their status, 98·5% of those aware were on ART, and 91·6% of those on ART had viral load suppression. The prevalance of viral load suppression among all people living with HIV was 91·8%, and varied by district-ranging from 85·3% in Gaborone to 100·0% in Selibe Phikwe. INTERPRETATION: BAIS V is the first population-based survey worldwide to report the achievement of the UNAIDS 95-95-95 goals, both overall and among women. Strategies to reach undiagnosed men and young people, including young women, are needed. FUNDING: US President's Emergency Plan for AIDS Relief.

Use of Expedited Partner Therapy for Pregnant Women Treated for Sexually Transmitted Infections in Gaborone, Botswana.

BACKGROUND: Partner notification and treatment for sexually transmitted infections are critical to prevent reinfection and reduce transmission. However, partner treatment rates are low globally. Expedited partner therapy (EPT), in which the patient delivers treatment directly to their partner, may result in more partners treated. We assessed partner notification and treatment outcomes among pregnant women in Gaborone, Botswana, including EPT intent, uptake, and effectiveness. METHODS: The Maduo study was a cluster-controlled trial evaluating the effect of antenatal Chlamydia trachomatis and Neisseria gonorrhoeae infection screening in pregnant women. The intervention arm received screening at first antenatal care (ANC), third-trimester, and postnatal care visits. The standard-of-care arm received screening postnatally. Participants screening positive were given options for partner treatment: contact slips, in-clinic treatment, or EPT. Self-reported partner notification and treatment outcomes were assessed at test-of-cure visit. RESULTS: Of 51 women who screened positive for C. trachomatis / N. gonorrhoeae at first ANC and returned for test of cure, 100% reported notifying their partner and 48 (94.1%) reported their partner received treatment. At third trimester 100% (n = 5), reported partners were treated. Before testing, EPT intent was lower than EPT uptake at all time points (first ANC: 17.9% vs. 80.4%; third-trimester: 57.1% vs. 71.4%; postnatal care: 0% vs. 80.0%). Partner treatment success was 100% among EPT users compared with 70% among nonusers ( P = 0.006). CONCLUSIONS: Partner notification and treatment success was high in this population. Despite low pretest intent to use EPT, uptake was high and associated with greater partner treatment success. Our findings suggest that EPT may be a successful partner treatment strategy to pursue in low- and middle-income countries.

Resurgent rotavirus diarrhoea outbreak five years after introduction of rotavirus vaccine in Botswana, 2018.

INTRODUCTION: Botswana had a resurgent diarrhea outbreak in 2018, mainly affecting children under five years old. Botswana introduced rotavirus vaccine (RotarixTM) into the national immunization programme in July 2012. Official rotavirus vaccine coverage estimates averaged 77.2% over the five years following introduction. MATERIALS AND METHODS: The outbreak was investigated using multiple data sources, including stool laboratory testing, immunization data review, water assessment, and vaccine storage assessment. We reviewed official reports of the routine immunization data from 2013 to 2017 and compared district-level rotavirus vaccine coverage with district-level attack rates during the outbreak. RESULTS: During the outbreak, a total of 228 stool samples were tested at the national health laboratory and 152 (67%) of the specimens were positive for rotavirus. A portion of adequate samples (80) were selected for referral to the Regional Reference Lab. The laboratory testing of 80 samples at the Regional Reference Laboratory in South Africa showed that 91% of the stool samples were positive for rotavirus, and the dominant strain 47/80 (58.7%) was G3P[8]. The immunization data showed that rotavirus vaccine coverage varied widely among districts, and there was no correlation between districts with high attack rates and those with low immunization coverage. Water assessment showed that some water sources were contaminated with E Coli. There was no problem with vaccine storage. CONCLUSION: The outbreak was caused by rotavirus G3P[8], a strain that was not common in the country prior to the outbreak. Despite the significant pressure and anxiety that outbreaks cause, the number of diarrhea cases and deaths were less compared to pre-vaccine era due to the impact of vaccination. This highlights the need for continuous implementation of high impact child survival interventions.

Assessment of unintended pregnancies, contraception, and abortion in Botswana.

Botswana has a policy of contraception for all that is delivered through a rights-based family planning program. The program combines a "rights-based family planning approach" with "supportive policies for contraception," and "a commitment to promote equitable access to modern contraception, and expand availability, method mix and uptake of modern contraceptive methods for all women and girls." However, abortion is legally restricted up to 16 weeks of pregnancy provided that provisions of Section 160-162 of the Botswana Penal Code Amendment Act 1991 are met, and that the termination of pregnancy is carried out by a registered medical practitioner in a health facility approved for the purpose. In 2020, the Ministry of Health and Wellness, Botswana, in collaboration with United Nations Population Fund and World Health Organization, conducted a strategic assessment of unintended pregnancies, contraception, unsafe abortion, and abortion services in Botswana. A consensus operational plan to address these issues was developed during a national stakeholder meeting in Gaborone, Botswana. The consensus reached was to avert unintended pregnancies, improve access to modern contraception, and open nationwide discussions around abortion in the community to enable positive change and decrease maternal morbidity and mortality from unsafe abortion. This article describes the findings of the assessment and outlines the foundation for new or modified services or practices to be developed and pilot tested.

Improved Indicators for Subnational Unmet Antiretroviral Therapy Need in the Health System: Updates to the Naomi Model in 2023.

BACKGROUND: Quantifying subnational need for antiretroviral therapy (ART) for HIV is challenging because people living with HIV (PLHIV) access health facilities in areas that may differ from their residence. We defined and demonstrated new indicators for PLHIV treatment needed to guide health system target setting and resource allocation. SETTING: Botswana. METHODS: We extended Naomi, a Bayesian small-area model for estimating district-level HIV indicators from national household survey and HIV service delivery data. We used model outputs for ART seeking probabilities in neighboring districts to define the "PLHIV (attending)" indicator representing the estimated number of PLHIV who would seek treatment at health facilities in a district, and "Untreated PLHIV attending" representing gaps in ART service provision. Botswana 2021 district HIV estimates were used to demonstrate new outputs and assess the sensitivity to uncertainty in district population sizes. RESULTS: Across districts of Botswana, estimated adult ART coverage in December 2021 ranged 90%-96%. In the capital city Gaborone, there were 50,400 resident PLHIV and 64,200 receiving ART, of whom 24% (95% CI: 20 to 32) were estimated to reside in neighboring districts. Applying ART attendance probabilities gave a "PLHIV attending" denominator of 68,300 and unmet treatment need of 4100 adults (95% CI: 3000 to 5500) for Gaborone health facilities. The facility-based "PLHIV attending" denominator was less-sensitive to fluctuations in district population size assumptions. CONCLUSIONS: New indicators provided more consistent targets for HIV service provision, but are limited by ART data quality. This challenge will increase as treatment coverage reaches high levels and treatment gaps are smaller.

HIV-sensitive social protection for unemployed and out-of-school young women in Botswana: An exploratory study of barriers and solutions.

Promotive social protection programs aim to increase income and capabilities and could help address structural drivers of HIV-vulnerability like poverty, lack of education and gender inequality. Unemployed and out-of-school young women bear the brunt of HIV infection in Botswana, but rarely benefit from such economic empowerment programs. Using a qualitative exploratory study design and a participatory research approach, we explored factors affecting perceived program benefit and potential solutions to barriers. Direct stakeholders (n = 146) included 87 unemployed and out-of-school young women and 59 program and technical officers in five intervention districts. Perceived barriers were identified in 20 semi-structured interviews (one intervention district) and 11 fuzzy cognitive maps. Co-constructed improvement recommendations were generated in deliberative dialogues. Analysis relied on Framework and the socioecological model. Overall, participants viewed existing programs in Botswana as ineffective and inadequate to empower vulnerable young women socially or economically. Factors affecting perceived program benefit related to programs, program officers, the young women, and their social and structural environment. Participants perceived barriers at every socioecological level. Young women's lack of life and job skills, unhelpful attitudes, and irresponsible behaviors were personal-level barriers. At an interpersonal level, competing care responsibilities, lack of support from boyfriends and family, and negative peer influence impeded program benefit. Traditional venues for information dissemination, poverty, inequitable gender norms, and lack of coordination were community- and structural-level barriers. Improvement recommendations focused on improved outreach and peer approaches to implement potential solutions. Unemployed and out-of-school young women face multidimensional, interacting barriers that prevent benefit from available promotive social protection programs in Botswana. To become HIV-sensitive, these socioeconomic empowerment programs would need to accommodate or preferentially attract this key population. This requires more generous and comprehensive programs, a more client-centered program delivery, and improved coordination. Such structural changes require a holistic, intersectoral approach to HIV-sensitive social protection.

Self-reported cardiovascular disease risk factor screening among people living with HIV vs. members of the general population in Botswana: a community-based study.

BACKGROUND: Morbidity and mortality due to cardiovascular diseases (CVDs) are high and increasing in low- and middle-income countries. People living with HIV (PLWH) are more likely to experience CVD than members of the general population. Therefore, we aimed to assess whether PLWH were more likely to have previously been screened for cardiovascular disease risk factors (CVDRFs) than people without HIV. METHODS: A population-based, cross-sectional study was conducted among individuals aged 16 to 68 years across 22 communities in Botswana from February to August 2017 as part of a larger community-based cluster randomized HIV treatment-as-prevention trial. Participants were asked if they had been screened for and counselled on cardiovascular disease risk factors (history of hypertension or blood pressure check, blood glucose and cholesterol measurements, weight check and weight control, tobacco smoking and cessation, alcohol use and physical activity) in the preceding 3 years. HIV testing was offered to those with an unknown HIV status. Multiple logistic regression analysis controlling for age and sex was used to assess the relationship between CVDRF screening and HIV status. RESULTS: Of the 3981 participants enrolled, 2547 (64%) were female, and 1196 (30%) were PLWH (93% already on antiretroviral therapy [ART]). PLWH were more likely to report previous screening for diabetes (25% vs. 19%, p < 0.001), elevated cholesterol (17% vs. 12%, p < 0.001) and to have had their weight checked (76% vs. 55%, p < 0.001) than HIV-uninfected participants. PLWH were also more likely to have received counselling on salt intake (42% vs. 33%, p < 0.001), smoking cessation (66% vs. 46%, p < 0.001), weight control (38% vs. 29%, p < 0.001), physical activity (46% vs. 34%, p < 0.001) and alcohol consumption (35% vs. 23%, p < 0.001) than their HIV-uninfected counterparts. Overall, PLWH were more likely to have received screening for and/or counselling on CVDRFs (adjusted odds ratio 1.84, 95% CI: 1.46-2.32, p < 0.001). CONCLUSION: PLWH were almost two times more likely to have been previously screened for CVDRFs than those without HIV, indicating a need for universal scale-up of integrated management and prevention of CVDs in the HIV-uninfected population.

Development, acceptability and usability of culturally appropriate survivor narrative videos for breast cancer treatment in Botswana: a pilot study.

OBJECTIVES: Narrative communication has demonstrated effectiveness in promoting positive health behaviours, delivering support and coping with complex decision-making. Formal research evaluating this intervention for cancer treatment in Africa is lacking. We aimed to develop, and assess acceptability and usability of survivor video narrative interventions for breast cancer treatment in Botswana. DESIGN: A pilot study design. SETTING: Single-centre, tertiary hospital, sub-Saharan Africa. PARTICIPANTS: Eight women, ≥18 years old, with stages I-III breast cancer were enrolled for the video intervention. 106 women, ≥18 years old, with stages I-IV breast cancer viewed the narrative videos and 98 completed the acceptability and usability surveys. INTERVENTION: Survivor narrative videos were developed using the theory of planned behaviour and using a purposive sample of Batswana, Setswana-speaking, breast cancer survivors, who had completed systemic treatment and surgery with high rates of adherence to the prescribed treatment plan. PRIMARY OUTCOMES: We assessed acceptability and usability among prospectively enrolled patients presenting for routine breast cancer care at Princess Marina Hospital in Botswana, using a 13-item survey. RESULTS: Participants expressed high acceptability and usability of the videos, including 99% (97/98) who strongly agreed/agreed that the video presentations were easy to understand, 92% (90/98) who would recommend to other survivors and 94% (92/98) who wished there were more videos. Additionally, 89% (87/98) agreed or strongly agreed that the one-on-one instruction on how to use the tablet was helpful and 87% (85/98) that the video player was easy to use. CONCLUSION: Culturally appropriate survivor video narratives have high acceptability and usability among patients with breast cancer in Botswana. There is an opportunity to leverage this intervention in routine breast cancer care for treatment support. Future studies will test the implementation and effectiveness of narrative videos on a wider scale, including for patients being treated for other cancers.

Neuropsychiatric manifestations of tuberous sclerosis in a young man in a psychiatric hospital in Botswana: a case report.

Tuberous sclerosis complex (TSC), first described in 1880, is a disorder that affects multiple systems. Its symptoms include seizures, intellectual disability, and angiofibromas. TSC is caused by mutations in the TSC1 and TSC2 genes and is inherited in an autosomal dominant manner. The present report describes the case of a patient with an unusual psychological presentation who was evaluated in a psychiatric hospital. A man with poorly managed epilepsy was brought to Botswana's only psychiatric hospital. After clinical assessment, a diagnosis of tuberous sclerosis complex was made, which was later confirmed through neuroimaging and genetic tests. Some of the patient's relatives also showed similar neuropsychiatric symptoms. Given that psychiatry may be the first medical contact for TSC patients, especially in low-resource settings, clinicians need to be knowledgeable of various neuropsychiatric conditions and be aware of the possibility of TSC in patients that present with neurocutaneous manifestations. A multidisciplinary team approach is vital for the investigation and management of such cases.

Hepatitis B surface antigen loss in individuals with chronic hepatitis B virus and HIV-1 infections in Botswana.

OBJECTIVES: We sought to determine hepatitis B surface antigen (HBsAg) loss and its predictors among people with chronic hepatitis B (CHB) infections and HIV (PWH) in Botswana. METHODS: Archived plasma samples from a cohort of PWH in Botswana (2013-2018) with 3 yearly time-points were used. Samples were screened for HBsAg, immunoglobulin M HBV core antibodies (anti-HBc IgM) and HBV e-antigen (HBeAg) at all time points. HBV deoxyribonucleic acid (DNA) quantification was done at baseline. The Wilcoxon rank-sum was used to compare continuous variables while the chi-squared test and Fishers exact test were used for categorical data wherever appropriate. Logistic regression was used to assess predictors of seroclearance. RESULTS: Of 141 participants with HBsAg-positive serology (HBsAg+) at baseline, 92.2% (131/141) [95% confidence interval (CI) 87.4-96.1] were persistently HBsAg+ at year 1. We report a HBsAg loss of 7.1% (10/141) (95% CI 3.9-12.6) among participants with negative HBeAg and negative IgM serologies. HBsAg loss was 6.3% (7/111) among antiretroviral therapy (ART)-experienced participants and 10.7% (3/28) (95% CI 0.4-5.0) in ART-naive participants. Most participants who had positive anti-HBc IgM serology and did not lose HBsAg were on either lamivudine (3TC)-based therapy or non-tenofovir disoproxil fumarate (TDF)-based therapy, except for one participant. The participants also had varying HBeAg status. HBsAg loss was independent of HIV viral load, CD4 + cell count, age, and sex. CONCLUSION: We report a HBsAg loss of 6.3% over a 3-year period among ART-experienced CHB participants. Future studies that focus on HBsAg loss in mono-infected patients and the possible correlation between HBeAg status and HBsAg loss are warranted.

Rapid dynamic changes of FL.2 variant: A case report of COVID-19 breakthrough infection.

We investigated intra-host genetic evolution using two SARS-CoV-2 isolates from a fully vaccinated (primary schedule x2 doses of AstraZeneca plus a booster of Pfizer), >70-year-old woman with a history of lymphoma and hypertension who presented a SARS-CoV-2 infection for 3 weeks prior to death due to COVID-19. Two full genome sequences were determined from samples taken 13 days apart with both belonging to Pango lineage FL.2: the first detection of this Omicron sub-variant in Botswana. FL.2 is a sub-lineage of XBB.1.9.1. The repertoire of mutations and minority variants in the Spike protein differed between the two time points. Notably, we also observed deletions within the ORF1a and Membrane proteins; both regions are associated with high T-cell epitope density. The internal milieu of immune-suppressed individuals may accelerate SARS-CoV-2 evolution; hence, close monitoring is warranted.

Long-term non-progression and risk factors for disease progression among children living with HIV in Botswana and Uganda: A retrospective cohort study.

OBJECTIVES: We utilize a large retrospective study cohort derived from electronic medical records to estimate the prevalence of long-term non-progression (LTNP) and determine the factors associated with progression among children infected with HIV in Botswana and Uganda. METHODS: Electronic medical records from large tertiary HIV clinical centers in Botswana and Uganda were queried to identify LTNP children 0-18 years enrolled between June 2003 and May 2014 and extract demographic and nutritional parameters. Multivariate subdistribution hazard analyses were used to examine demographic factors and nutritional status in progression in the pre-antiretroviral therapy era. RESULTS: Between the two countries, 14,246 antiretroviral therapy-naïve children infected with HIV were enrolled into clinical care. The overall proportion of LTNP was 6.3% (9.5% in Botswana vs 5.9% in Uganda). The median progression-free survival for the cohort was 6.3 years, although this was lower in Botswana than in Uganda (6.6 vs 8.8 years; P <0.001). At baseline, the adjusted subdistribution hazard ratio (aHRsd) of progression was increased among underweight children (aHRsd 1.42; 95% confidence interval [CI]: 1.32-1.53), enrolled after 2010 (aHRsd 1.32; 95% CI 1.22-1.42), and those from Botswana (aHRsd 2; 95% CI 1.91-2.10). CONCLUSIONS: In our study, the prevalence of pediatric LTNP was lower than that observed among adult populations, but progression-free survival was higher than expected. Underweight, year of enrollment into care, and country of origin are independent predictors of progression among children.

Nontargeted Screening of Contaminants of Emerging Concern in the Glen Valley Wastewater Treatment Plant, Botswana.

There is growing concern about the prevalence and impact of contaminants of emerging concern (CECs). The environmental monitoring of CECs has, however, been limited in low- and middle-income countries due to the lack of advanced analytical instrumentation locally. In the present study we employed a nontargeted and suspect screening workflow via liquid chromatography coupled with high-resolution mass spectrometry (HRMS) to identify known and unknown pollutants in the Glen Valley wastewater treatment plant, Botswana, complemented by analysis of groundwater samples. The present study represents the first HRMS analysis of CECs in water samples obtained in Botswana. Suspect screening of 5942 compounds qualitatively identified 28 compounds, including 26 pharmaceuticals and two illicit drugs (2-ethylmethcathinone and 11-nor-9-carboxy-Δ9-tetrahydrocannabinol). Nontargeted analysis tentatively identified the presence of 34 more compounds including (5ξ)-12,13-dihydroxypodocarpa-8,11,13-trien-7-one, 12-aminododecanoic acid, atenolol acid, brilliant blue, cyclo leucylprolyl, decanophenone, DL-carnitine, N,N'-dicyclohexylurea, N4-acetylsulfamethoxazole, NP-003672, and 24 polyethylene glycol polymers. The highest number of detections were in influent wastewater (26 CECs) followed by effluent wastewater (10 CECs) and, lastly, groundwater (4 CECs). Seventeen CECs detected in the influent water were not detected in the effluent waters, suggesting reduced emissions due to wastewater treatment. Two antiretroviral compounds (abacavir and tenofovir) were detected in the influent and effluent sources. This suggests that wastewater treatment plants are a major pathway of chemical pollution to the environment in Botswana and will help inform prioritization efforts for monitoring and remediation that is protective of these key ecosystems.

A simple and rapid external standard calibration HPLC method for determination of lumefantrine in dried blood spot samples from malaria patients in Botswana.

A simple external calibration liquid chromatography-diode array detector method was developed, validated, and applied for the determination of lumefantrine (Lum) in dried blood spot (DBS) samples collected from malaria patients in Botswana. The samples were validated in accordance with the United States Food and Drug Administration guidelines for bioanalytical methods after sample preparation using solid-liquid extraction. Separation was achieved using an XTerra C18 column (50 × 4.6 mm, 5 µm), and a binary solvent system of acetonitrile and water adjusted to pH 2.3 was used as the mobile phase. The validated method was applied for the determination of Lum in DBS samples collected from malaria patients infected with Plasmodium falciparum in Botswana. The calibration curve was linear between 0.5 and 12 µg/mL with a coefficient of determination (R2 ) of 0.9996. The limit of detection and the lower limit of quantification were 0.5 and 1.4 µg/mL, respectively. The efficiency of extraction measured as percentage recovery ranged between 84.2% and 107.8% at the three quality control (QC) levels, that is, low QC, mid QC, and high QC. In conclusion, data suggest that the method is suitable for the determination of trace Lum in biofluids and can also be used for therapeutic drug monitoring and pharmacokinetic profiling.

Vulnerable young women and frontline service providers identify options to improve the HIV-sensitivity of social protection programmes in Botswana: A modified Policy Delphi approach.

Poverty, lack of education and gender inequality make unemployed and out-of-school young women extremely vulnerable to HIV infection. Promotive social protection programmes aim to increase livelihood and capabilities and could empower this priority population to act on HIV prevention choices. In Botswana, they rarely benefit from such programmes.A modified Policy Delphi engaged a panel of 22 unemployed and out-of-school young women and eight frontline service providers to consider alternative policy and practice options, and tailor available programmes to their own needs and social situation. The panel assessed the desirability and feasibility of improvement proposals and, in a second round, ranked them for relative importance.Nearly all 40 improvement proposals were considered very desirable and definitely, or possibly, feasible, and panellists prioritised a wide range of proposals. Frontline service providers stressed foundational skills, like life skills and second chance education. Young women preferred options with more immediate benefits. Overall, panellists perceived positive role models for programme delivery, access to land and water, job skills training, and stipends as most important to empower HIV-vulnerable young women. Results suggest ample policy space to make existing social protection programmes in Botswana more inclusive of unemployed and out-of-school young women, hence more HIV-sensitive.

Regional anaesthesia practice in public hospitals in Botswana: A cross-sectional study.

INTRODUCTION: Little is known about the regional anesthesia practice in low resources settings (LRS). The aim of this study was to describe the regional anesthesia capacity, characteristics of regional anesthesia practice, and challenges and solutions of practicing safe regional anesthesia in public hospitals in Botswana. METHODS: This was a cross-sectional survey of anesthesia providers working in public hospitals in Botswana. A purposive sampling method of public hospitals was used to achieve representation of different hospital levels across Botswana. Paper-based questionnaires were sent to anesthesia providers from selected hospitals. Descriptive statistics were used for analysis. RESULTS: Questionnaires were distributed to 47 selected anesthesia providers from selected hospitals; 38 (80.9%) were returned. Most participants were nurse anesthetists and medical officers (57.8%). All hospitals perform spinal anesthesia; however, other regional techniques were performed by a small number of participants in one referral hospital. Most hospitals had adequate regional anesthesia drugs and sedation medications, however, most hospitals (except one referral hospital) lacked ultrasound machine and the regional anesthesia kit. The common challenges reported were lack of knowledge and skills, lack of equipment and supplies, and lack of hospital engagement and support. Some solutions were proposed such as regional anesthesia training and engaging the hospital management to get resources. CONCLUSIONS: The results of this study suggest that spinal anesthesia is the most common regional anesthesia technique performed by anesthesia providers working in public hospitals in Botswana followed by few upper limb blocks. However, most public hospitals lack enough training capacity, equipment, and supplies for regional anesthesia. More engagement of the hospital management, investment in regional anesthesia resources, and training are needed in order to improve the regional anesthesia capacity and provide safe surgery and anesthesia in Botswana.

Lower academic performance among children with perinatal HIV exposure in Botswana.

INTRODUCTION: Studies have reported a higher risk of suboptimal neurodevelopment among children who are HIV-exposed uninfected (HEU) compared to children HIV-unexposed uninfected (HUU). Actual academic performance among school-aged children by HIV exposure status has not been studied. METHODS: Academic performance in Mathematics, Science, English, Setswana and overall among children enrolled in the Botswana-based FLOURISH study who were attending public primary school and ranging in age from 7.1 to 14.6 years were compared by HIV exposure status using a Cochran-Mantel-Haenszel test. Lower academic performance was defined as a grade of "C" or lower (≤60%). Unadjusted and adjusted logistic regression models were fit to assess for an association between HIV exposure and lower academic performance. RESULTS: Between April 2021 and December 2022, 398 children attending public primary school enrolled in the FLOURSH study, 307 (77%) were HEU. Median age was 9.4 years (IQR 8.9-10.2). Only 17.9% of children HEU were breastfeed versus 100% of children HUU. Among children HEU, 80.3% had foetal exposure to three-drug antiretroviral treatment, 18.7% to zidovudine only and 1.0% had no antiretroviral exposure. Caregivers of children HEU were older compared to caregivers of children HUU (median 42 vs. 36 years) and more likely to have no or primary education only (15.0% vs. 1.1%). In unadjusted analyses, children HEU were more likely to have lower overall academic performance compared to their children HUU (odds ratio [OR]: 1.96 [95% confidence interval (CI): 1.16, 3.30]), and lower performance in Mathematics, Science and English. The association was attenuated after adjustment for maternal education, caregiver income, breastfeeding, low birth weight and child sex (aOR: 1.86 [95% CI: 0.78, 4.43]). CONCLUSIONS: In this Botswana-based cohort, primary school academic performance was lower among children HEU compared to children HUU. Biological and socio-demographic factors, including child sex, appear to contribute to this difference. Further research is needed to identify modifiable contributors, develop screening tools to identify the risk of poor academic performance and design interventions to mitigate risk.
