Addressing the gap in health economics data to support national cancer control plans in low- and middle-income countries: The Childhood Cancers Budgeting Rapidly to Incorporate Disadvantaged Groups for Equity (CC-BRIDGE) tool.

BACKGROUND: National cancer control plans (NCCPs) are complex public health programs that incorporate evidence-based cancer control strategies to improve health outcomes for all individuals in a country. Given the scope of NCCPs, small and vulnerable populations, such as patients with childhood cancer, are often missed. To support planning efforts, a rapid, modifiable tool was developed that estimates a context-specific national budget to fund pediatric cancer programs, provides 5-year scale-up scenarios, and calculates annual cost-effectiveness. METHODS: The tool was codeveloped by teams of policymakers, clinicians, and public health advocates in Zimbabwe, Zambia, and Uganda. The 11 costing categories included real-world data, modeled data, and data from the literature. A base-case and three 5-year scale-up scenarios were created using modifiable inputs. The cost-effectiveness of the disability-adjusted life years averted was calculated. Results were compared with each country's projected gross domestic product per capita for 2022 through 2026. RESULTS: The number of patients/total budget for year 1 was 250/$1,109,366 for Zimbabwe, 280/$1,207,555 for Zambia, and 1000/$2,277,397 for Uganda. In year 5, these values were assumed to increase to 398/$5,545,445, 446/$4,926,150, and 1594/$9,059,331, respectively. Base-case cost per disability-adjusted life year averted/ratio to gross domestic product per capita for year 1, assuming 20% survival, was: $807/0.5 for Zimbabwe, $785/0.7 for Zambia, and $420/0.5 for Uganda. CONCLUSIONS: This costing tool provided a framework to forecast a budget for childhood-specific cancer services. By leveraging minimal primary data collection with existing secondary data, local teams obtained rapid results, ensuring that childhood cancer budgeting is not neglected once in every 5 to 6 years of planning processes.

Prevention of treatment abandonment remains an important challenge to increase survival of Wilms tumor in sub-Saharan Africa: A report from Wilms Africa-CANCaRe Africa.

BACKGROUND: The Wilms Africa studies implemented an adapted Wilm's tumor (WT) treatment protocol in sub-Saharan Africa in two phases. Phase I began with four sites and provided out-of-pocket costs. Phase II expanded the number of sites, but lost funding provision. Objective is to describe the outcomes of Phase II and compare with Phase I. METHODS: Wilms Africa Phase I (n = 4 sites; 2014-2018) and Phase II (n = 8 sites; 2021-2022) used adapted treatment protocols. Funding for families' out-of-pocket costs was provided during Phase I but not Phase II. Eligibility criteria were age less than 16 years and newly diagnosed unilateral WT. We documented patients' outcome at the end of planned first-line treatment categorized as treatment abandonment, death during treatment, and disease-related events (death before treatment, persistent disease, relapse, or progressive disease). Sensitivity analysis compared outcomes in the same four sites. RESULTS: We included 431 patients in Phase I (n = 201) and Phase II (n = 230). The proportion alive without evidence of disease decreased from 69% in Phase I to 54% in Phase II at all sites (p = .002) and 58% at the original four sites (p = .04). Treatment abandonment increased overall from 12% to 26% (p < .001), and was 20% (p = .04) at the original four sites. Disease-related events (5% vs. 6% vs. 6%) and deaths during treatment (14% vs. 14% vs. 17%) were similar. CONCLUSION: Provision of out-of-pocket costs was important to improve patient outcomes at the end of planned first-line treatment in WT. Prevention of treatment abandonment remains an important challenge.

Surgical aspects and outcomes after nephrectomy for Wilms tumour in sub-Saharan Africa: A report from Wilms Africa Phase II-CANCaRe Africa.

BACKGROUND: Wilms tumour (WT) is one of the common and curable cancer types targeted by the Global Initiative for Childhood Cancer. Tumour excision is essential for cure. This analysis focuses on surgical outcomes of patients with WT in sub-Saharan Africa. METHODS: We implemented a risk-stratified WT treatment guideline as a multicentre, prospective study across eight hospitals and six countries. Eligibility criteria were age 6 months to 16 years, unilateral WT, surgery performed after preoperative chemotherapy and diagnosed between 1 January 2021 and 31 December 2022. Data collection included a specific surgical case report form (CRF). RESULTS: The study registered 230 patients, among whom 164 (71.3%) had a nephrectomy. Ninety-eight percent of patients had a completed surgical CRF. Out 164 patients, 50 (30.5%) had distant metastases. Median tumour diameter at surgery was 11.0 cm. Lymph node sampling was done in 122 (74.3%) patients, 34 (20.7%) had intraoperative tumour rupture, and for 18 (10.9%), tumour resection involved en bloc resection of another organ. Tumour size at surgery was significantly correlated with tumour rupture (p < .01). With a median follow-up of 17 months (range: 2-33), 23 (14.0%) patients have relapsed. Twenty-two (13.4%) patients abandoned treatment post nephrectomy. Two-year event-free survival was 60.4% ± 4.7% with treatment abandonment as an event. CONCLUSION: Survival post nephrectomy is challenged by treatment abandonment, treatment-related mortality and relapse. Large tumours after preoperative chemotherapy were associated with a higher risk of tumour rupture. Earlier diagnosis and access to radiotherapy are expected to improve survival.

Enhancing information on stage at diagnosis for childhood cancer in Africa.

BACKGROUND/PURPOSE: Stage at diagnosis is an important metric in treatment and prognosis of cancer, and also in planning and evaluation of cancer control. In sub-Saharan Africa (SSA), for the latter, the only data source is the population-based cancer registry (PBCR). For childhood cancers, the 'Toronto Staging Guidelines' have been developed to facilitate abstraction of stage by cancer registry personnel. Although the feasibility of staging using this system has been shown, there is limited information on the accuracy of staging. METHODS: A panel of case records of six common childhood cancers was established. A total of 51 cancer registrars from 20 SSA countries staged these records, using Tier 1 of the Toronto guidelines. The stage that they assigned was compared with that decided by two expert clinicians. RESULTS: The registrars assigned the correct stage for 53%-83% of cases (71% overall), with the lowest values for acute lymphocytic leukaemia (ALL), retinoblastoma and non-Hodgkin lymphoma (NHL), and the highest for osteosarcoma (81%) and Wilms tumour (83%). For ALL and NHL, many unstageable cases were mis-staged, probably due to confusion over the rules for dealing with missing data; for the cases with adequate information, accuracy was 73%-75%. Some confusion was observed over the precise definition of three stage levels of retinoblastomas. CONCLUSIONS: A single training in staging resulted in an accuracy, for solid tumours, that was not much inferior to what has been observed in high-income settings. Nevertheless, some lessons were learned on how to improve both the guidelines and the training course.

Viral load testing among pregnant women living with HIV in Mutare district of Manicaland province, Zimbabwe.

BACKGROUND: Viral load (VL) monitoring of pregnant women living with HIV (PWLHIV) and antiretroviral therapy (ART) may contribute to lowering the risk of vertical transmission of HIV. The aims of this study were to assess the uptake of HIV VL testing among PWLHIV at entry to the prevention-of-mother-to-child transmission (PMTCT) services and identify facilitatory factors and barriers to HIV VL access. METHODS: A retrospective, cross-sectional study was conducted at 15 health facilities in Mutare district, Manicaland Province, Zimbabwe from January to December 2018. This analysis was complemented by prospective interviews with PWLHIV and health care providers between October 2019 and March 2020. Quantitative data were analysed using descriptive and inferential statistical methods. Risk factors were evaluated using multivariate logistic regression. Open-ended questions were analysed and recurring and shared experiences and perceptions of PWLHIV and health care providers identified. RESULTS: Among 383 PWLHIV, enrolled in antenatal care (ANC) and receiving ART, only 121 (31.6%) had a VL sample collected and 106 (88%) received their results. Among these 106 women, 93 (87.7%) had a VL < 1000 copies/mL and 77 (73%) a VL < 50 copies/mL. The overall median duration from ANC booking to VL sample collection was 87 (IQR, 7-215) days. The median time interval for the return of VL results from date of sample collection was 14 days (IQR, 7-30). There was no significant difference when this variable was stratified by time of ART initiation. VL samples were significantly less likely to be collected at local authority compared to government facilities (aOR = 0.28; 95% CI 0.16-0.48). Barriers to VL testing included staff shortages, non-availability of consumables and sub-optimal sample transportation. Turnaround time was prolonged by the manual results feedback system. CONCLUSIONS AND RECOMMENDATION: The low rate of HIV VL testing among PWLHIV in Mutare district is a cause for concern. To reverse this situation, the Ministry of Health should consider interventions such as disseminating antiretroviral guidelines and policies electronically, conducting regular PMTCT mentorship for clinical staff members, and utilising point of care testing and telecommunication devices like mHealth to increase uptake of VL testing and improve results turnaround time.

Stage at diagnosis and survival by stage for the leading childhood cancers in three populations of sub-Saharan Africa.

The lack of accurate population-based information on childhood cancer stage and survival in low-income countries is a barrier to improving childhood cancer outcomes. In our study, data from three population-based registries in sub-Saharan Africa (Abidjan, Harare and Kampala) were examined for children aged under 15. We assessed the feasibility of assigning stage at diagnosis according to Tier 1 of the Toronto Childhood Cancer Stage Guidelines for patients with non-Hodgkin lymphoma [including Burkitt lymphoma (BL)], retinoblastoma and Wilms' tumour. Patients were actively followed-up, allowing calculation of 3-year relative survival by cancer type and registry. Stage-specific observed survival was estimated. The cohort comprised 381 children, of whom half (n = 192, 50%) died from any cause within 3 years of diagnosis. Three-year relative survival varied by malignancy and location and ranged from 17% [95% confidence interval (CI) = 6%-33%] for BL in Harare to 57% (95% CI = 31%-76%) for retinoblastoma in Kampala. Stage was assigned for 83% of patients (n = 317 of 381), with over half having metastatic or advanced disease at diagnosis (n = 166, 52%). Stage was a strong predictor of survival for each malignancy; for example, 3-year observed survival was 88% (95% CI = 68%-96%) and 13% (4%-29%) for localised and advanced BL, respectively (P < .001). These are the first data on stage distribution and stage-specific survival for childhood cancers in Africa. They demonstrate the feasibility of the Toronto Stage Guidelines in a low-resource setting and highlight the value of population-based cancer registries in aiding our understanding of the poor outcomes experienced by this population.

Trends in childhood cancer incidence in sub-Saharan Africa: Results from 25 years of cancer registration in Harare (Zimbabwe) and Kyadondo (Uganda).

We examined trends in childhood cancer incidence in sub-Saharan Africa using data from two population-based cancer registries in Harare (Zimbabwe) and Kyadondo (Uganda) with cases classified according to the International Classification of Childhood Cancer and explored reasons for observed variations and changes. Over the whole 25-year period (1991-2015) studied, there were only small, and nonsignificant overall trends in incidence. Nevertheless, within the period, peaks in incidence occurred from 1996 to 2001 in Harare (Zimbabwe) and from 2003 to 2006 in Kyadondo (Uganda). Kaposi sarcoma and non-Hodgkin lymphoma accounted for the majority of the cases during these periods. These fluctuations in incidence rates in both registries can be linked to similar trends in the prevalence of HIV, and the availability of antiretroviral therapy. In addition, we noted that, in Harare, incidence rates dropped from 2003 to 2004 and 2007 to 2008, correlating with declines in national gross domestic product. The results indicate that the registration of childhood cancer cases in resource-poor settings is linked to the availability of diagnostic services mediated by economic developments. The findings highlight the need for specialised diagnostic and treatment programmes for childhood cancer patients as well as positive effects of HIV programmes on certain childhood cancers.

The cost-effectiveness of treating childhood cancer in 4 centers across sub-Saharan Africa.

BACKGROUND: The treatment of childhood cancer often is assumed to be costly in African settings, thereby limiting advocacy and policy efforts. The authors determined the cost and cost-effectiveness of maintaining childhood cancer centers across 4 hospitals throughout sub-Saharan Africa. METHODS: Within hospitals representing 4 countries (Kenya, Nigeria, Tanzania, and Zimbabwe), cost was determined either retrospectively or prospectively for all inputs related to operating a pediatric cancer unit (eg, laboratory costs, medications, and salaries). Cost-effectiveness was calculated based on the annual number of newly diagnosed patients, survival rates, and life expectancy. RESULTS: Cost per new diagnosis ranged from $2400 to $31,000, attributable to variances with regard to center size, case mix, drug prices, admission practices, and the treatment abandonment rate, which also affected survival. The most expensive cost input was found to be associated with medication in Kenya, and medical personnel in the other 3 centers. The cost per disability-adjusted life-year averted ranged from 0.3 to 3.6 times the per capita gross national income. Childhood cancer treatment therefore was considered to be very cost-effective by World Health Organization standards in 2 countries and cost-effective in 1 additional country. In all centers, abandonment of treatment was common; modeling exercises suggested that public funding of treatment, additional psychosocial personnel, and modifications of inpatient policies would increase survival rates while maintaining or even improving cost-effectiveness. CONCLUSIONS: Across various African countries, childhood cancer treatment units represent cost-effective interventions. Cost-effectiveness can be increased through the control of drug prices, appropriate policy environments, and decreasing the rate of treatment abandonment. These results will inform national childhood cancer strategies across Africa.

Fever and neutropenia outcomes and areas for intervention: A report from SUCCOUR - Supportive Care for Children with Cancer in Africa.

BACKGROUND: Death during paediatric cancer treatment is common in sub-Saharan Africa. Using the infrastructure of Supportive Care for Children with Cancer in Africa (SUCCOUR), our objective was to describe fever and neutropenia (FN) characteristics and outcomes in order to identify potential areas for future intervention. METHODS: A multicentre prospective, observational cohort study was conducted in sub-Saharan Africa. Data were collected from September 2019 to March 2020. Children below 16 years with newly diagnosed cancer treated with curative intent were included. Data were abstracted in real time using standardised case report forms by trained personnel. Characteristics and outcomes of FN during the first 3 months of treatment were documented. RESULTS: A total of 252 patients were included (median age 6.0, range 0.2-15.0 years, 54% male). The most common cancer was Burkitt lymphoma (63/252, 25%). Among 104 FN episodes, 21 (21%) were associated with prolonged neutropenia (>1 week) and 32 (31%) were associated with profound neutropenia (absolute neutrophil count <0.1 × 109 /L). In 10/104 (10%) episodes, empiric antibiotics were started within 1 hour following fever onset and in 16/104 (15%) episodes, a blood culture was obtained before starting antibiotics. Malaria parasitaemia was detected in four of 104 (4%). A total of 11/104 (11%) patients died in the FN episodes. CONCLUSIONS: Although in most, FN was not associated with prolonged or profound neutropenia, 11% resulted in death. Areas to target include blood cultures prior to antibiotics and earlier initiation of empiric antibiotics. Future efforts should modify FN practices to reduce treatment-related mortality.

Early death and treatment-related mortality: A report from SUCCOUR - Supportive Care for Children with Cancer in Africa.

BACKGROUND: Deaths during paediatric cancer treatment are common in Africa. It is often difficult to distinguish between treatment-related and disease-related causes. To prevent these deaths, it is important to study them and identify the cause. The Supportive Care for Children with Cancer in Africa (SUCCOUR) programme enabled a study with the objective to identify the reasons for early death during treatment. METHODS: We conducted a multicentre prospective, observational cohort study in sub-Saharan Africa. Children younger than 16 years with newly diagnosed cancer treated with curative intent were included from 1 September 2019 until 30 March 2020. Data were abstracted in real time by trained personnel using standardised case report forms. The treating clinician's assessment of the cause of death and signs, symptoms and laboratory values of patients who died during the first 3 months of treatment (early death) were documented. RESULTS: We included 252 patients (median age 6.0, range 0.2-15.0 years, 54% male). The most common cancer was Burkitt lymphoma (63/252, 25%). Fifteen percent of patients (37/252) died during the first 3 months of treatment. Of these 37 patients, 33 (89%) died of a treatment-related cause. Treatment-related mortality of all patients in the first 3 months of treatment was 13% (33/252). CONCLUSION: Fifteen percent of patients had an early death during treatment and 13% had a treatment-related death. This suggests the need to improve supportive care. Implementation of supportive care pathways adapted to local circumstances may be helpful.

Treatment abandonment: A report from the collaborative African network for childhood cancer care and research-CANCaRe Africa.

BACKGROUND: 'Treatmentabandonment' is a common and preventable cause of childhood cancer treatment failure in low- and middle-income countries (LMIC). Risk factors and effective interventions in LMIC are reported. Poverty and costs of treatment are perceived as overriding causes in sub-Saharan Africa. The objective of this study was to study potential determinants of treatment abandonment, including aspects of treatment costs in sub-Saharan Africa, to be better informed for planned future interventions. METHODS: A multicentre, prospective, observational, cohort study was conducted in five hospitals in sub-Saharan Africa. Children younger than 16 years with newly diagnosed cancer treated as inpatient with curative intent were included. The occurrence of treatment abandonment and potential determinants including aspects of treatment costs were documented during the first 3 months of treatment. RESULTS: We included 252 patients (median age 6.0, range 0.2-15.0 years, 54% male). The most common cancer was Burkitt lymphoma (63/252, 25%). Seven percent of patients (18 of 252) abandoned treatment. Two thirds (65%, 163/252) of patients had to borrow money to reach the hospital for the diagnosis and start of treatment. Treatment abandonment occurred more frequently in families who had to borrow money (16/163, 10%) versus those who did not (2/89, 2%; p = .026). CONCLUSIONS: Limiting costs for families and improved counselling may reduce treatment abandonment. Development and implementation of interventions to reduce treatment abandonment are required in sub-Saharan Africa.

Improvement of overall survival in the Collaborative Wilms Tumour Africa Project.

INTRODUCTION: The Collaborative Wilms Tumour (WT) Africa Project implemented an adapted WT treatment guideline in six centres in sub-Saharan Africa. The primary objectives were to describe abandonment of treatment, death during treatment, event-free survival (EFS) and relapse following implementation. An exploratory objective was to compare outcomes with the baseline evaluation, a historical cohort preceding implementation. METHODS: The Collaborative WT Africa Project is a multi-centre prospective clinical trial that began in 2014. Funding was distributed to all participating centres and used to cover treatment, travel and other associated costs for patients. Patient characteristics, tumour characteristics and events were described. RESULTS: In total, 201 WT patients were included. Two-year EFS was 49.9 ± 3.8% when abandonment of treatment was considered an event. Relapse of disease occurred in 21% (42 of 201) of all included patients and in 26% (42 of 161) of those who had a nephrectomy. Programme implementation was associated with significantly higher survival without evidence of disease at the end of treatment (52% vs 68.5%, P = .002), significantly reduced abandonment of treatment (23% vs 12%, P = .009) and fewer deaths during treatment (21% vs 13%, P = .06). CONCLUSION: This collaborative implementation of an adapted WT treatment guideline, using relatively simple and low-cost interventions, was feasible. Two-year EFS was almost 50%. In addition, a significant decrease in treatment abandonment and an increase in survival at the end of treatment were observed compared to a pre-implementation cohort. Future work should focus on decreasing deaths during treatment and will include enhancing supportive care.

Sepsis in cancer patients residing in Zimbabwe: spectrum of bacterial and fungal aetiologies and their antimicrobial susceptibility patterns.

BACKGROUND: Cancer and sepsis comorbidity is a major public health problem in most parts of the world including Zimbabwe. The microbial aetiologies of sepsis and their antibiograms vary with time and locations. Knowledge on local microbial aetiologies of sepsis and their susceptibility patterns is critical in guiding empirical antimicrobial treatment choices. METHODS: This was a descriptive cross-sectional study which determined the microbial aetiologies of sepsis from blood cultures of paediatric and adult cancer patients obtained between July 2016 and June 2017. The TDR-X120 blood culture system and TDR 300B auto identification machine were used for incubation of blood culture bottles and identification plus antimicrobial susceptibility testing, respectively. RESULTS: A total of 142 participants were enrolled; 50 (35.2%) had positive blood cultures, with 56.0% Gram positive, 42.0% Gram-negative bacteria and 2.0% yeast isolated. Common species isolated included coagulase negative Staphylococcus spp. (CoNS) (22.0%), E. coli (16.0%), K. pneumoniae (14.0%), E. faecalis (14.0%) and S. aureus (8.0%). Gram-negative isolates exhibited high resistance to gentamicin (61.9%) and ceftriaxone (71.4%) which are the empiric antimicrobial agents used in our setting. Amikacin and meropenem showed 85.7 and 95.2% activity respectively against all Gram-negative isolates, whilst vancomycin and linezolid were effective against 96.2 and 100.0% of all Gram-positive isolates respectively. We isolated 10 (66.7%) extended spectrum ß-lactamase (ESBL) amongst the E. coli and K. pneumoniae isolates. Ten (66.7%) of the Staphylococcus spp. were methicillin resistant. CONCLUSIONS: CoNS, E. coli, K. pneumoniae, E. faecalis and S. aureus were the major microbial drivers of sepsis amongst cancer patients in Zimbabwe. Most isolates were found to be resistant to commonly used empirical antibiotics, with isolates exhibiting high levels of ESBL and methicillin resistance carriage. A nationwide survey on microbial aetiologies of sepsis and their susceptibility patterns would assist in the guidance of effective sepsis empiric antimicrobial treatment among patients with cancer.

'If nurses were in our shoes would they breastfeed their own babies?' A qualitative inquiry on challenges faced by breastfeeding mothers on the PMTCT programme in a rural community in Zimbabwe.

BACKGROUND: The Prevention of Mother to Child Transmission (PMTCT) of HIV programme in Zimbabwe has had remarkable success despite the country's economic challenges. The aim of this study was to explore the challenges faced by breastfeeding mothers on the PMTCT programme. METHOD: Narratives from 15 women (age range 19-35 years) were collected at two rural health facilities in Zimbabwe through in-depth interviews over a period of 6 months. Thematic analysis was used to describe breastfeeding mothers' experiences and challenges of being on the PMTCT programme. RESULTS: The findings suggest that breastfeeding women on the PMTCT programme face challenges that include internal, external and institutional stigma and discrimination. Women reported a sense of powerlessness in decision making on following through with the PMTCT programme and were ambivalent regarding disclosure of their HIV status to their partners and significant others. CONCLUSION: HIV and AIDS programmes should pay attention to women's readiness for interventions. There is need to understand women's life experiences to ensure informed and targeted programming for PMTCT.

Risky traditional practices and prevention of mother-to-child transmission of HIV: the case of Chiota community in Zimbabwe.

The objective of this study was to explore cultural practices that could expose babies to HIV infection during the postnatal period in Chiota community in Zimbabwe. Purposively selected and gender disaggregated members of the community (n = 231) were informants to 23 focus group discussions and 8 semi-structured key-informant interviews. Data were analysed thematically. Emerging themes relating to risky practices were rituals surrounding open fontanelle, toning of child's sexual libido, initiation of sex after childbirth, treatment of eye and ear infections, tongue-tie and pre-mastication. These practices exposed babies to bodily fluids such as saliva, breast milk, vaginal fluids, pre-cum and semen which in turn put the babies at low to high risk of contracting HIV. This paper discusses implications for these risky practices in prevention of mother-to-child transmission of HIV. There is, therefore, need for studies to establish the prevalence of these practices.

Stigma in Pediatric Cancer: An Exploratory Study of Osteosarcoma and Retinoblastoma in Guatemala, Jordan, and Zimbabwe.

PURPOSE: Stigma is an understudied barrier to health care acceptance in pediatric oncology. We sought to explore the stigma experience, including its impact on cancer treatment decision making, and identify strategies to mitigate stigma for patients with osteosarcoma and retinoblastoma in Guatemala, Jordan, and Zimbabwe. METHODS: Participants included caregivers, adolescent patients (age 12-19 years), and health care clinicians. A semistructured interview guide based on The Health Stigma and Discrimination Framework (HSDF) was adapted for use at each site. Interviews were conducted in English, Spanish, Arabic, or Shona, audio-recorded, translated, and transcribed. Thematic analysis focused on stigma practices, experiences, outcomes, drivers, mitigators, and interventions. RESULTS: We conducted 56 interviews (28 caregivers, 19 health care clinicians, nine patients; 20 in Guatemala, 21 in Jordan, 15 in Zimbabwe). Major themes were organized into categories used to adapt the HSDF to global pediatric cancer care. Themes were described similarly across all sites, ages, and diagnoses, with specific cultural nuances noted. Pediatric cancer stigma was depicted as an isolating and emotional experience beginning at diagnosis and including internalized and associative stigma. Stigma affected decision making and contributed to negative outcomes including delayed diagnosis, treatment abandonment, regret, and psychosocial fragility. Overcoming stigma led to positive outcomes including resilience, treatment adherence, pride, and advocacy. Identified stigma drivers and mitigators were linked to potential interventions. CONCLUSION: Participants describe a shared stigma experience that transcends geography, cultural context, age, and diagnosis. Stigma manifestations have the potential to impact medical decision making and affect long-term psychological outcomes. Stigma assessment tools and interventions aimed at stigma mitigation including educational initiatives and support groups specific to pediatric cancer should be the focus of future research.

Impact of acute, oral ingestion of hypoxoside from African potato on hepatic and renal function tests in HIV infected patients on combination antiretroviral therapy.

OBJECTIVES: African potato (hypoxis hemerocallidea) is used against HIV to enhance immune-function, although no studies have evaluated its use in HIV infected individuals on combination antiretroviral therapy. The study aimed to evaluate the acute effects of orally administered hypoxoside, a constituent of African potato, on the hepatic and renal function in HIV infected individuals on tenofovir disoproxil fumarate/ lamivudine/ efavirenz regimen. METHODS: This was an open-label, two-period, fixed-sequence, pre-post test study, pilot design. Ethical approval was obtained from Medical Research Council of Zimbabwe (MRCZ A/2045) and Medicines Control Authority of Zimbabwe (MCAZ CT134/2016). Blood samples were collected before and after administration of African potato tablets. Tablets were administered orally once daily at 15mg/ kg hypoxoside for 10 days. Hepatic function tests (ALT, AST, ALP, GGT, albumin, total/ direct bilirubin); renal function tests (eGFR, blood urea nitrogen, creatinine), serum electrolytes (sodium, potassium, chloride) were assayed. STATA was used for statistical analysis. RESULTS: Twenty-six participants were enrolled (85% female). Median age (range) was 43 (28-52) years. Most had overweight Body Mass Index (46%) and were married (54%). No statistical difference was noted during hypoxoside for AST/ ALT/ ALP/ GGT/ albumin/ bilirubin. There were no changes in creatinine/ eGFR/ electrolytes. A mean significant increase in total protein (p=0.04) and decrease in blood urea nitrogen (p=0.04) were noted. CONCLUSION: Short-term exposure to hypoxoside from African potato appeared safe and was not associated with clinically significant changes in hepatic, renal function tests/electrolytes. There is further need to evaluate extent of systemic exposure during long-term use in a larger population.

An Exploration of Barriers and Enablers of Retention in a Program to Reduce Vertical Transmission of HIV at Health Centers in Zimbabwe.

BACKGROUND: Poor retention in the prevention of women in prevention of vertical transmission programs remains a formidable common setback in elimination of HIV/AIDS. It creates new problems such as poor health outcomes and increased incidence of vertical transmission of HIV. There is a dearth of qualitative information to explain poor retention of women in prevention of mother-to-child transmission (PMTCT) programs in Zimbabwe. The purpose of the study was to explore the enablers and barriers of retention of women in PMTCT programs. METHODS: This was a basic qualitative study conducted at four health centers in Zimbabwe. Four audiotaped focus group discussions were conducted with 34 pregnant or breastfeeding women coming for PMTCT services at the health centers. Descriptive statistics was used for sample demographics. Transcripts were analyzed through latent content analysis based on the Graneheim and Lundman method. RESULTS: Maternal determination, a four-tier support system, and an inspiring health package were enablers to retention in the PMTCT program while uninspired individual engagement, paternalism, and undesirable PMTCT-related events were barriers to retention of women in the PMTCT program. CONCLUSIONS: Reinforcing hope for the women and their children, active management of side effects of antiretroviral medicine, consistent peer support, enhancing confidentiality among community cadres, and commitment from community or religious leaders may improve retention of women in PMTCT programs; for women with HIV during pregnancy, delivery and post-natal care.
