Internalized stigma adversely impacts childhood cancer survivors, limiting their ability to reintegrate with their communities and maintain social networks. However, the impact of internalized stigma on children undergoing cancer treatment is unknown, and no interventions exist to mitigate it. The Activating Events-Beliefs-Consequences (ABC) model from Cognitive Behavioral Theory (CBT) has been used to analyze internalized stigma and inform interventional work. This study employs the ABC model as a conceptual framework to explore how internalized stigma manifests for children recently diagnosed with osteosarcoma and retinoblastoma in Guatemala, Jordan, and Zimbabwe. We conducted semi-structured interviews with nine adolescent patients (aged 12-18), 28 caregivers, and 19 clinicians at tertiary cancer centers in Guatemala, Jordan, and Zimbabwe. Interviews occurred in Spanish, Arabic, Shona, and English and were transcribed and translated into English for analysis. Two coders independently coded transcripts, resolving disagreements through consensus and third-party adjudication. A framework analysis used the ABC model to understand manifestations of internalized stigma, defined a priori as "a patient's own adoption of negative societal beliefs or feelings, including changes in self-identification." Patients, caregivers, and clinicians all described internalized stigma in pediatric cancer patients. Cancer-related physical changes and community stigma activated internalized stigma. Patients responded to these events by forming beliefs about their appearance, abilities, normalcy, and future, which shaped their behaviors and emotions. While some patients internalized stigmatizing beliefs about themselves and experienced negative consequences, others maintained resilient self-beliefs that fostered adaptive behaviors and emotions. Knowledge about the disease, supportive interactions with survivors and other patients, and caregiver support promoted stigma resilience. Our results demonstrate that internalized stigma impacts pediatric cancer patients from the time of diagnosis, highlighting the relevance of the ABC model in understanding this complex phenomenon. Our findings suggest CBT-based interventions that target patient beliefs, address identified activating events, and enhance multilevel support could help mitigate internalized stigma in pediatric cancer patients. Additional research should explore the efficacy of such interventions, the transferability of our findings to children with other cancer diagnoses and to various geographies, as well as how internalized stigma evolves across the cancer continuum.

BackgroundIn our quest to improve pediatric neuro-oncological care in government tertiary institutions, growing calls to set up a recurring monthly MDT meeting finally came to fruition in 2024 despite the challenges characteristic of setting up a new program in a developing nation. A team comprising of, neurosurgeons, pediatric oncologists, radio-oncologists, pathologists, radiologists, and international collaborators from Cape Town and St Jude’s all convened for this monthly virtual meeting. Here we enumerate, reflect on, and map a way forward to address these issues.MethodologyAs we celebrate the first anniversary of the program, we are auditing the cases discussed, interventions done, morbidity and mortality, and explore growth potential going forward.ResultsWe have not only surpassed our expectations in terms of numbers but also realized tangible benefits brought by the multi-disciplinary efforts in streamlining neuro-oncological services in Zimbabwe. Challenges were encountered, and ongoing efforts are aimed at addressing these challenges through further engagement with the international community as well as public-private partnerships, notably the Kidzcan charity organization. Timely imaging, pathology, and radiotherapy capacity as well as the availability of much-needed surgical equipment are some of the notable constraints.ConclusionIn a nutshell, a multidisciplinary approach to neuro-oncological patients affords tailor-made individualized care to every patient and helps in formulating local treatment protocols best suited for our unique challenges. There is still room for improvement through further collaboration. This program can serve as a template for similar programs in resource-limited settings.

BackgroundHIV prevalence in Harare reached a maximum of around 33% of adults in 1995, before falling to 12% in 2019. We examine trends in the incidence of Kaposi sarcoma (KS), non-Hodgkin lymphoma (NHL), Hodgkin lymphoma, and squamous cell conjunctival cancers (SCCCs) in the population of Harare in relation to changes in HIV prevalence, and the increasing availability and use of antiretroviral therapy (ART).MethodsData from the population-based cancer registry of Harare are used to calculate incidence rates for the Black (African) population for the years 1990-2019.ResultsIncidence of KS increased to a peak in the late 1990s, after which rates declined, especially at younger ages. Mean age at diagnosis increased by about 8 years in men and 6 years in women. SCCC shows a similar trend to that of KS, with a dramatic 10-fold increase in incidence, followed by an equivalent fall. Although Hodgkin lymphoma showed no change in incidence over the 30-year period, rates of NHL progressively increased. Incidence in younger adults (aged younger than 44) stabilized after about 2001 but continued to increase in older individuals.ConclusionsThe availability of high-quality cancer registry data over a long period has provided a unique opportunity to study the effects of the epidemic of HIV-AIDs and of ART availability on the risk of cancer in an African population. As HIV prevalence fell and ART coverage expanded, incidence of KS and SCCC declined, whereas for NHL the trends suggest that long-term infection with HIV may pose an increased risk, despite ART.

BackgroundCervical cancer is a common cancer worldwide, with > 85% of deaths occurring in Lower- and Middle-Income Countries where resources for screening programs are limited. Women living with HIV (WLHIV) are at increased risk. HPV test-and-treat is a screening strategy where women with HPV are offered ablative treatment of the cervix to reduce the risk of invasive cancer. WLHIV tend to have more extensive cervical lesions, necessitating more specialised surgical treatments.MethodACTG A5282 was a randomised, open-label, Phase 2 trial conducted in seven countries that compared a cytology-based screening strategy to HPV test-and-treat for cervical cancer prevention in WLHIV. Women with cervical lesions inappropriate for ablative treatment were assigned to Arm C and underwent colposcopy and directed biopsies. Loop electro-excision procedure was performed if high-grade lesions (bHSIL) were present on cervical biopsies. Women were followed 26 weeks later for repeat evaluations. The Clopper-Pearson exact method was used to construct the 95% confidence interval for the proportion of WLHIV with lesions inappropriate for cryotherapy. Logistic regression models were used to assess the factors associated with these lesions.ResultsOf 1046 women screened, 156 (88%) were Black/Non-Hispanic, with a median age of 36 years; 80% were on ART, and 73% had an HIV-1 RNA < 200 copies/mL. On cervical colposcopy, 17% (179/1046, 95% CI 14.9–19.4%) had cervical lesions inappropriate for cervical ablation. Among 428 (44%) women with High-risk HPV (hrHPV) detected, 112 (26%, 95% CI 22.2%, 30.5%) had cervical lesions inappropriate for ablative therapy. hrHPV was found more commonly among women having lesions inappropriate for ablative therapy as compared to lesions appropriate for ablative therapy (70% vs 54%, p < .001). Among 128 women with extensive cervical lesions undergoing colposcopic biopsies, 43 (34%) had bHSIL detected. Among women undergoing LEEP treatment of bHSIL, 24% had bHSIL detected 26 weeks later.ConclusionCervical lesions inappropriate for ablative therapy were common among WLHIV. This has implications for cervical cancer programs as these lesions can only be optimally treated with surgical therapies such as loop electroexcision procedures, and the capacity for this procedure should be increased to maximise cervical cancer prevention outcomes.

BackgroundThe COVID-19 pandemic had a profound impact on healthcare and ophthalmology services globally. Numerous studies amongst various medical and surgical specialties showed a reduction in patient attendance and surgical procedures performed. Prior published ophthalmic literature focused on specific types of procedures and were usually single centre. The current study attempts to quantify the impact on a larger scale, namely that of sub-Saharan Africa, and to include all ophthalmic subspecialties.MethodsThis is a retrospective analysis of the surgical records from 17 ophthalmology centres in seven countries located in East, Central, West and Southern Africa. The date of declaration of the first lockdown was used as the beginning of the pandemic and the pivot point to compare theatre records one year prior to the pandemic and the first year of the pandemic. We examined the total number of surgical procedures over the two year period and categorized them according to ophthalmic subspecialty and type of procedure performed. We then compared the pre-pandemic and pandemic surgical numbers over the two year period.ResultsThere were 26,357 ophthalmic surgical procedures performed with a significant decrease in the first year of the pandemic (n = 8942) compared to the year prior to the pandemic (n = 17,415). The number of surgical procedures performed was lower in the first year of the pandemic compared to the year prior to the pandemic by 49% [Incidence rate ratio (IRR) 0.51, 95% CI 0.41–0.64), 27% (0.73, 0.55–0.99), 46% (0.54, 0.30–0.99), 40% (0.60, 0.39–0.92) and 59% (0.41, 0.29–0.57) in sub-Saharan Africa (4 regions combined), West, Central, East and Southern Africa, respectively]. The number of surgical procedures in the different sub-specialty categories in sub-Saharan Africa (4 regions combined) was significantly lower in the first year of the pandemic compared to the year prior to the pandemic, except for glaucoma (IRR 0.72, 95% CI 0.52–1.01), oncology (0.71, 0.48–1.05), trauma (0.90, 0.63–1.28) and vitreoretinal (0.67, 0.42–1.08) categories.ConclusionThis study provides insight into the impact of the COVID-19 pandemic in multiple regions and countries on the African continent. The identification of which surgical subspecialty was most affected by the COVID-19 pandemic in each region allows for better planning and resource allocation to address these backlogs.

We investigated the clinical profile, complications, and outcomes of inpatients with COVID-19 at Parirenyatwa Hospital, Harare, across the first two waves of SARS-CoV-2 infection, and factors associated with mortality. We conducted a prospective cohort study on all patients admitted to the COVID-19 unit. Data were extracted from medical records and negative binomial regression with robust standard errors was used to assess the association between sociodemographic and clinical characteristics and mortality. Cox Regression was used for sensitivity analysis. Of 563 people admitted with COVID-19 between 2 July 2020 and 19 March 2021, 214 (38.0%) died, 340 were discharged and 9 transferred. The median age was 56 (IQR 44-68) years and 53.8% were male. Overall, 38.8% experienced a complication, the most common being acute kidney injury (17.9%) and hyperglycaemia (13.1%). The most common comorbidity was hypertension (41.3%) followed by diabetes (28.6%), HIV (12.1%), cardiovascular disease (10.9%) and chronic kidney disease (7.8%). Among participants who stayed in the ward for more than 1 night, mortality was higher in patients with comorbidity compared to those without any comorbidity (38.7% vs 25.5%, risk ratio (RR) = 1.52 (95% CI 1.11, 2.07), p = 0.008). After adjusting for oxygen saturation, comorbidities, sex and pregnancy, mortality was higher in the second wave than in the first (adjusted RR 1.23, 95% CI 1.00-1.51, p = 0.05). In the second wave 57/161 (35.4%) deaths were attributed to lack of resources, mainly human resources. The mortality rate was high and clinical COVID-19 care needs to pay careful attention to patient monitoring for complications and management of comorbidities. This will require addressing the critical health workforce shortage issues. Prevention of COVID-19 including vaccination particularly among individuals with comorbidities remains a high priority.

Household air pollution (HAP) from biomass fuels significantly contributes to cardio-respiratory morbidity and premature mortality globally. Particulate matter (PM), one of the pollutants generated, remains the most accurate indicator of household air pollution. Determining indoor air concentration levels and factors influencing these levels at the household level is of prime importance, as it objectively guides efforts to reduce household air pollution. This paper describes household factors associated with increased PM2.5 levels in Zimbabwean rural household kitchens. Our HAP and lung health in women study enrolled 790 women in rural and urban households in Zimbabwe between March 2018 and December 2019. Here, we report data from 148 rural households using solid fuel as the primary source of fuel for cooking and heating and where indoor air samples were collected. Data on kitchen characteristics and practices were collected cross-sectionally using an indoor walk-through survey and a modified interviewer-administered questionnaire. An Air metrics miniVol Sampler was utilized to collect PM2.5 samples from the 148 kitchens over a 24 h period. To identify the kitchen features and practices that would likely influence PM2.5 concentration levels, we applied a multiple linear regression model. The measured PM2.5 ranged from 1.35 μg/m3 to 1940 μg/m3 (IQR: 52.1-472). The PM2.5 concentration levels in traditional kitchens significantly varied from the townhouse type kitchens, with the median for each kitchen being 291.7 μg/m3 (IQR: 97.2-472.2) and 1.35 μg/m3 (IQR: 1.3-97.2), respectively. The use of wood mixed with other forms of biomass was found to have a statistically significant association (p < 0.001) with increased levels of PM2.5 concentration. In addition, cooking indoors was strongly associated with higher PM2.5 concentrations (p = 0.012). Presence of smoke deposits on walls and roofs of the kitchens was significantly associated with increased PM2.5 concentration levels (p = 0.044). The study found that kitchen type, energy type, cooking place, and smoke deposits were significant predictors of increased PM2.5 concentrations in the rural households. Concentrations of PM2.5 were high as compared to WHO recommended exposure limits for PM2.5. Our findings highlight the importance of addressing kitchen characteristics and practices associated with elevated PM2.5 concentrations in settings where resources are limited and switching to cleaner fuels may not be an immediate feasible option.
