RESUMO

INTRODUCTION: Post-traumatic seizures (PTS) are common among patients with depressed skull fractures (DSF). Understanding the burden of post traumatic seizures and the factors associated among adult patients with DSF is important to improve clinical care. OBJECTIVE: To determine the prevalence and factors associated with post-traumatic seizures among adult patients with DSF at Mulago National Referral hospital (MNRH). METHODS: A cross-sectional study was conducted among 333 study participants between March 2021 and February 2022. Socio-demographic, clinical laboratory factors and anti-seizure medications were collected using a study questionnaire. Data was analysed to determine the prevalence of PTS and factors associated with occurrence of PTS among patients with DSF. RESULTS: The mean age (±SD) of study participants was 31.2, (±10.5) years, with a male to female ratio of 10.4:1. Nearly half of the study participants had attained secondary level of education, while 31.6 % (105) were peasants (subsistence farmers). The overall prevalence of PTS among DSF study participants was 16.2 % (54participants). Late presentation of PTS was the highest at 9.0 % (30) followed by early PTS at 3.9 % [13] and immediate PTS at 3.3 % [11]. Moderate Glasgow coma score (GCS: 9-13), p < 0.015, severe traumatic brain injury (GCS: 3-8), p < 0.026 at the time of admission and midline brain shift (≥5mm), p < 0.009 were associated with PTS. Phenytoin (94.3 %) was the most commonly used ASM followed by phenobarbitone (1.4 %) and Valproate (1.1 %) among study participants. CONCLUSION: Patients with moderate and severe traumatic brain injury and midline brain shift were associated with post traumatic seizures. Early identification and intervention may reduce the burden of posttraumatic seizures in this category of patients.

RESUMO

Reproductive characteristics are known risk factors for breast cancer but, other than recent birth, their role as prognostic factors is less clear, and has not been studied in Sub-Saharan Africa (SSA). In this setting, we examined whether reproductive factors independently influence breast cancer survival in a subset of the African Breast Cancer-Disparities in Outcomes cohort study. In 1485 women with incident breast cancer recruited between 2014 and 2017, we examined birth cohort changes in reproductive factors, and used Cox models to examine whether reproductive characteristics were associated with all-cause mortality after adjusting for confounders (age, stage, treatment, HIV, and social factors). Four years after diagnosis, 822 (56%) women had died. Median parity was 4 (IQR = 2, 6) and 209 (28%) of premenopausal women had had a recent birth (<3 years prior to cancer diagnosis). Each pregnancy was associated with a 5% increase (95% CI: 2%, 8%) in mortality rates, which held among postmenopausal women (5%, [1%-9%]). Pre-menopausal women with a recent birth had 52% (20%, 92%) higher mortality rates. Fertility trends by birth cohort showed declining parity, increasing age at first birth and declining age at last birth, however the impact of these population-level changes on future average survival was predicted to be very small (<3% absolute gain).

RESUMO

BACKGROUND: Expansive intracranial hematomas (EIH) following traumatic brain injury (TBI) continue to be a public health problem in Uganda. Data is limited regarding the neurosurgical outcomes of TBI patients. This study investigated the neurosurgical outcomes and associated risk factors of EIH among TBI patients at Mulago National Referral Hospital (MNRH). METHODS: A total of 324 subjects were enrolled using a prospective cohort study. Socio-demographic, risk factors and complications were collected using a study questionnaire. Study participants were followed up for 180 days. Univariate, multivariable, Cox regression analyses, Kaplan Meir survival curves, and log rank tests were sequentially conducted. P-values of < 0.05 at 95% Confidence interval (CI) were considered to be statistically significant. RESULTS: Of the 324 patients with intracranial hematomas, 80.6% were male. The mean age of the study participants was 37.5 ± 17.4 years. Prevalence of EIH was 59.3% (0.59 (95% CI: 0.54 to 0.65)). Participants who were aged 39 years and above; PR = 1.54 (95% CI: 1.20 to 1.97; P = 0.001), and those who smoke PR = 1.21 (95% CI: 1.00 to 1.47; P = 0.048), and presence of swirl sign PR = 2.26 (95% CI: 1.29 to 3.95; P = 0.004) were found to be at higher risk for EIH. Kaplan Meier survival curve indicated that mortality at the 16-month follow-up was 53.4% (95% CI: 28.1 to 85.0). Multivariate Cox regression indicated that the predictors of mortality were old age, MAP above 95 mmHg, low GCS, complications such as infection, spasticity, wound dehiscence, CSF leaks, having GOS < 3, QoLIBRI < 50, SDH, contusion, and EIH. CONCLUSION: EIH is common in Uganda following RTA with an occurrence of 59.3% and a 16-month higher mortality rate. An increased age above 39 years, smoking, having severe systemic disease, and the presence of swirl sign are independent risk factors. Old age, MAP above 95 mmHg, low GCS, complications such as infection, spasticity, wound dehiscence, CSF leaks, having a GOS < 3, QoLIBRI < 50, ASDH, and contusion are predictors of mortality. These findings imply that all patients with intracranial hematomas (IH) need to be monitored closely and a repeat CT scan to be done within a specific period following their initial CT scan. We recommend the development of a protocol for specific surgical and medical interventions that can be implemented for patients at moderate and severe risk for EIH.

RESUMO

Informed consent for emergency surgery is a process in which a patient or their next of kin must make quick decisions required for surgery in a life-threatening situation or surgery that may have life-altering outcomes. The objective of the study was to describe patients and their next of kin experiences and factors influencing the informed consent process in two urban university teaching hospitals in Uganda. METHODS: A cross-sectional survey involving patients who underwent emergency surgery and their next of kin was conducted in two tertiary care hospitals; one public and one private-not-for profit institution. A questionnaire was administered to collect sociodemographic information, type of Surgery that was done, how informed consent was obtained and experiences and expectations from the informed consent process. Univariate and multivariate analyses of the variables was done. RESULTS: We collected data from 210 patients from a public hospital and 170 from a private-not-for profit hospital. Overall, most patients did not have the risks of the surgery communicated to them (79.7%), were not given alternative options (87.6%) and had no opportunity to ask questions (57.4%). Patients at the private institution had 3.35 times the odds of expecting the consent form to be explained to them than those at the public institution. Patients at the public hospital had 0.12 times the odds of preferring to have consent administered by a nurse than patients at the private institution OR 0.12 (0.05-0.29, p < 0.001). Patients in the public institution had 0.18 times the odds of preferring to have consent administered by a doctor than patients in the private institution OR 0.18 (0.08-0.45, p < 0.001). CONCLUSION: Patients in both public and private institutions are not informed about the risks of surgery, alternative options and are not given the opportunity to ask questions. Interpretation of the findings of this study on patient preferences on who administered consent though statistically significant were inconclusive due to the responses not being mutually exclusive.

RESUMO

BACKGROUND: Comprehensive breast cancer management is essential to achieve high breast cancer survival; however, detailed reports of the treatment regimens received by patients are scarce in sub-Saharan Africa where survival is low. We aimed to examine treatment initiation, guideline concordance, and abandonment in patients with non-metastatic breast cancer in sub-Saharan Africa from the African Breast Cancer-Disparities in Outcomes (ABC-DO) prospective cohort. METHODS: The ABC-DO prospective cohort study recruited women (aged ≥18 years) with newly diagnosed invasive breast cancer in eight hospitals across five sub-Saharan African countries (Namibia, Nigeria, Uganda, South Africa, and Zambia). We analysed treatments received by women who were classified as non-metastatic (M0) at the initial presentation. Data on surgery, radiotherapy, and systemic therapies were obtained from medical records and a self-reported follow-up questionnaire at 6 months after the diagnosis, follow-up calls every 3 months, and a baseline questionnaire. Initiation, completion, and abandonment of treatment modalities and combined therapy regimens were examined overall, by country-specific groups, and by clinical factors relevant for guideline-based treatment. FINDINGS: Of 2313 women recruited into the ABC-DO study between Sept 10, 2014, and Dec 31, 2017, 2226 had histologically or clinically confirmed breast cancer. Of these 2226 women, 510 were excluded from the present analysis because 378 had metastatic disease, 37 were prevalent cases (defined as those previously diagnosed with breast cancer >2 years before baseline), 82 had unknown TNM stage, and 13 were White or Asian women in South Africa (number was too small for analysis). After a median follow-up of 5·2 years (IQR 4·6-5·9), 1163 (68%) of 1716 women underwent breast cancer surgery. Surgery and systemic therapy (ie, multimodality treatment) with radiotherapy was initiated in 370 (36%) of 1028 women with localised tumours versus 156 (23%) of 688 women with locally advanced tumours, whereas multimodality treatment without radiotherapy was initiated in 386 (38%) versus 167 (24%) women, respectively. Of 1530 patients requiring chemotherapy (which excludes 105 who died within 6 months after baseline), 1013 (66%) initiated treatment of neoadjuvant chemotherapy or surgery within 3 months after baseline, which was adequately completed by 359 (35%) of 1013 women, marginally completed by 284 (28%), abandoned by 200 (20%), and unknown in 151 (15%). 19 (2%) women died within 6 months after chemotherapy initiation. Of 1375 women in whom endocrine therapy was indicated, this treatment was initiated in 920, and lasted at least 3 years in 367 (40%) women. Treatment disparities between country-specific groups were substantial for all therapy regimens. INTERPRETATION: A high proportion of patients with non-metastatic breast cancer did not initiate, did not fully complete, or abandoned treatment with surgery, systemic therapy, radiotherapy, or an appropriate combination of these, highlighting the need for improved treatment access and completion in sub-Saharan Africa to potentially prevent premature breast cancer deaths.

RESUMO

Slum dwellers across Africa have been targeted in interventions whose impacts remain unclear. We evaluated the impact of a livelihood intervention on the sexual and reproductive health and rights (SRHR) of young people in the slum areas of Kampala, Uganda. We carried out a repeated cross-sectional survey in 2014 and 2017 to examine the impact of community-based livelihood interventions on the SRHR of young people in the slum areas of Kampala, Uganda. Impacts were observed such as reduced sexual activity, reduction in aspects of gender-based violence attitudes and beliefs, increased access to and decision-making about contraceptive and family-planning services, increased availability and affordability of SRHR services, reduced need to seek further knowledge on SRHR, reduced barriers to HIV testing, and increased knowledge of health responsibilities. Unexpected results included: increased proportion of young people who had ever had sex, decreased mean age of sexual debut, unaffordability of contraceptives, and increased culturally shaped attitudes and social norms related to gender-based violence. We observed no impact on condom use, consensual sex and sexual assault, the number of sexual partners, knowledge about HIV/AIDS, stigma and discrimination against people living with HIV/AIDS, affordability of male and female condoms, and uptake of HIV testing services. Rights-based interventions are crucial to how we understand the SRHR of young people in complex sociocultural environments. While the livelihood interventions made significant impacts on the SRHR of young people, there are questions about how such interventions address deeply rooted sociocultural practices to maximise outcomes.

RESUMO

BACKGROUND: The majority of the prognostic scoring tools for peritonitis are impractical in low resource settings because they are complex while others are quite costly. The quick Sepsis-related Organ Failure Assessment (qSOFA) score and the Physiologic Indicators for Prognosis in Abdominal Sepsis (PIPAS) severity score are two strictly bedside prognostic tools but their predictive ability for mortality of peritonitis is yet to be compared. We compared the predictive ability of the qSOFA criteria and the PIPAS severity score for in-hospital mortality of peritonitis. METHOD: This was a prospective cohort study on consecutive peritonitis cases managed surgically in a tertiary hospital in Uganda between October 2020 to June 2021. PIPAS severity score and qSOFA score were assessed preoperatively for each case and all cases were then followed up intra- and postoperatively until discharge from the hospital, or up to 30 days if the in-hospital stay was prolonged; the outcome of interest was in-hospital mortality. We used Receiver Operating Characteristic curve analysis to assess and compare the predictive abilities of these two tools for peritonitis in-hospital mortality. All tests were 2 sided (p < 0.05) with 95% confidence intervals. RESULTS: We evaluated 136 peritonitis cases. Their mean age was 34.4 years (standard deviation = 14.5). The male to female ratio was 3:1. The overall in-hospital mortality rate for peritonitis was 12.5%. The PIPAS severity score had a significantly better discriminative ability (AUC = 0.893, 95% CI 0.801-0.986) than the qSOFA score (AUC = 0.770, 95% CI 0.620-0.920) for peritonitis mortality (p = 0.0443). The best PIPAS severity cut-off score (a score of > = 2) had sensitivity and specificity of 76.5%, and 93.3% respectively, while the corresponding values for the qSOFA criteria (score > = 2), were 58.8% and 98.3% respectively. CONCLUSIONS: The in-hospital mortality in this cohort of peritonitis cases was high. The PIPAS severity score tool has a superior predictive ability and higher sensitivity for peritonitis in-hospital mortality than the qSOFA score tool although the latter tool is more specific. We recommend the use of the PIPAS severity score as the initial prognostic tool for peritonitis cases in the emergency department.

RESUMO

BACKGROUND: Practice-based learning is crucial in forming appropriate strategies for improving learning among the medical students that support the country's understaffed health sector. Unsatisfactory learning consequently results in poor performance of students and poor quality of health care workforce in the long run. Exploring the perceptions about the current practice-based learning system and how to improve is thus vital. This study set out to explore the perceptions of Orthopaedic medicine students and their supervisors about practice-based learning at a tertiary training hospital. METHODS: This was an exploratory phenomenological qualitative study that involved in-depth interviews among 10 Orthopedic students during their rotation in the emergency ward of Mulago hospital and 6 of their supervisors. Interviews were audio-recorded, transcribed, and then imported into Atlas ti 8.3 for analysis. The data were coded and grouped into themes relating to perceptions of practice-based learning, general inductive analysis was used. The general inductive approach involved condensing the raw textual data into a brief and summary format. The summarized format was then analyzed to establish clear links between the perceptions of practice-based learning and the summary findings derived from the raw data. RESULTS: The mean age of the students was 23 ± 1.5 years. Four out of the six supervisors were Orthopaedic officers while the remaining two were principal Orthopaedic officers, four out of the six had a university degree while the other two were diploma holders. The main themes arising were hands-on skills, an unconducive learning environment, the best form of learning, and having an undefined training structure. Particularly, the perceptions included the presence of too many students on the wards during the rotation, frequent stock-outs of supplies for learning, and supervisors being overwhelmed caring for a large number of patients. CONCLUSION: Barriers to satisfactory practice-based learning were overcrowding on the wards and insufficient training materials. To improve practice-based learning, adequate learning materials are required and the number of students enrolled needs to be appropriate for the student - supervisor ratio.

RESUMO

BACKGROUND: Arm and shoulder problems (ASP), including lymphedema, were common among women with breast cancer in high-income countries before sentinel lymph node biopsy became the standard of care. Although ASP impair quality of life, as they affect daily life activities, their frequency and determinants in Sub-Saharan Africa remain unclear. METHODS: All women newly diagnosed with breast cancer at the Namibian, Ugandan, Nigerian, and Zambian sites of the African Breast Cancer-Disparities in Outcomes (ABC-DO) cohort study were included. At each 3-month follow-up interview, women answered the EORTC-QLQ-Br23 questionnaire, including three ASP items: shoulder/arm pain, arm stiffness, and arm/hand swelling. We estimated the cumulative incidence of first self-reported ASP, overall and stratified by study and treatment status, with deaths treated as competing events. To identify determinants of ASP, we estimated cause-specific hazard ratios using Cox models stratified by study site. RESULTS: Among 1476 women, up to 4 years after diagnosis, 43% (95% CI 40-46), 36% (33-38) and 23% (20-25), respectively, self-reported having experienced arm/shoulder pain, stiffness and arm/hand swelling at least once. Although risks of self-reported ASP differed between sites, a more advanced breast cancer stage at diagnosis, having a lower socioeconomic position and receiving treatment increased the risk of reporting an ASP. CONCLUSION: ASP are very common in breast cancer survivors in Sub-Saharan Africa. They are influenced by different factors than those observed in high-income countries. There is a need to raise awareness and improve management of ASP within the African setting.

RESUMO

Most breast cancer patients in sub-Saharan Africa are diagnosed at advanced stages after prolonged symptomatic periods. In the multicountry African Breast Cancer-Disparities in Outcomes cohort, we dissected the diagnostic journey to inform downstaging interventions. At hospital presentation for breast cancer, women recalled their diagnostic journey, including dates of first noticing symptoms and health-care provider (HCP) visits. Negative binomial regression models were used to identify correlates of the length of the diagnostic journey. Among 1429 women, the median (inter-quartile range) length (months) of the diagnostic journey ranged from 11.3 (5.7-21.2) in Ugandan, 8.2 (3.4-16.4) in Zambian, 6.5 (2.4-15.7) in Namibian-black to 5.6 (2.3-13.1) in Nigerian and 2.4 (0.6-5.5) in Namibian-non-black women. Time from first HCP contact to diagnosis represented, on average, 58% to 79% of the diagnostic journey in each setting except Nigeria where most women presented directly to the diagnostic hospital with advanced disease. The median number of HCPs visited was 1 to 4 per woman, but time intervals between visits were long. Women who attributed their initial symptoms to cancer had a 4.1 months (absolute) reduced diagnostic journey than those who did not, while less-educated (none/primary) women had a 3.6 months longer journey than more educated women. In most settings the long journey to breast cancer diagnosis was not primarily due to late first presentation but to prolonged delays after first presentation to diagnosis. Promotion of breast cancer awareness and implementation of accelerated referral pathways for women with suspicious symptoms are vital to downstaging the disease in the region.

RESUMO

We examined the geospatial dimension of delays to diagnosis of breast cancer in a prospective study of 1541 women newly diagnosed in the African Breast Cancer-Disparities in Outcomes (ABC-DO) Study. Women were recruited at cancer treatment facilities in Namibia, Nigeria, Uganda and Zambia. The baseline interview included information used to generate the geospatial features: urban/rural residence, travel mode to treatment facility and straight-line distances from home to first-care provider and to diagnostic/treatment facility, categorized into country/ethnicity (population)-specific quartiles. These factors were investigated in relation to delay in diagnosis (≥3 months since first symptom) and late stage at diagnosis (TNM: III, IV) using logistic regression, adjusted for population group and sociodemographic characteristics. The median (interquartile range) distances to first provider and diagnostic and treatment facilities were 5 (1-37), 17 (3-105) and 62 (5-289) km, respectively. The majority had a delay in diagnosis (74%) and diagnosis at late stage (64%). Distance to first provider was not associated with delay in diagnosis or late stage at diagnosis. Rural residence was associated with delay, but the association did not persist after adjustment for sociodemographic characteristics. Distance to the diagnostic/treatment facility was associated with delay (highest vs lowest quartile: odds ratio (OR) = 1.56, 95% confidence interval (CI) = 1.08-2.27) and late stage (overall: OR = 1.47, CI = 1.05-2.06; without Nigerian hospitals where mostly local residents were treated: OR = 1.73, CI = 1.18-2.54). These findings underscore the need for measures addressing the geospatial barriers to early diagnosis in sub-Saharan African settings, including providing transport or travel allowance and decentralizing diagnostic services.

RESUMO

The presence of preexisting morbidities poses a challenge to cancer patient care. There is little information on the profile and prevalence of multi-morbidities in breast cancer patients across middle income countries (MIC) to lower income countries (LIC) in sub-Saharan Africa (SSA). The African Breast Cancer-Disparities in Outcomes (ABC-DO) breast cancer cohort spans upper MICs South Africa and Namibia, lower MICs Zambia and Nigeria and LIC Uganda. At cancer diagnosis, seven morbidities were assessed: obesity, hypertension, diabetes, asthma/chronic obstructive pulmonary disease, heart disease, tuberculosis and HIV. Logistic regression models were used to assess determinants of morbidities and the influence of morbidities on advanced stage (stage III/IV) breast cancer diagnosis. Among 2189 women, morbidity prevalence was the highest for obesity (35%, country-specific range 15-57%), hypertension (32%, 15-51%) and HIV (16%, 2-26%) then for diabetes (7%, 4%-10%), asthma (4%, 2%-10%), tuberculosis (4%, 0%-8%) and heart disease (3%, 1%-7%). Obesity and hypertension were more common in upper MICs and in higher socioeconomic groups. Overall, 27% of women had at least two preexisting morbidities. Older women were more likely to have obesity (odds ratio: 1.09 per 10 years, 95% CI 1.01-1.18), hypertension (1.98, 1.81-2.17), diabetes (1.51, 1.32-1.74) and heart disease (1.69, 1.37-2.09) and were less likely to be HIV positive (0.64, 0.58-0.71). Multi-morbidity was not associated with stage at diagnosis, with the exception of earlier stage in obese and hypertensive women. Breast cancer patients in higher income countries and higher social groups in SSA face the additional burden of preexisting non-communicable diseases, particularly obesity and hypertension, exacerbated by HIV in Southern/Eastern Africa.

RESUMO

BACKGROUND: Approximately a decade after the inaugural Fundamentals of Surgical Research Course (FSRC) at the West African College of Surgeons meeting (2008), the Association for Academic Surgery expanded the course offering to the annual meeting of the College of Surgeons of East, Central and Southern Africa (COSECSA). After the second annual offering of the course in 2019, participants were surveyed to assess the impact of the course. METHODS: A survey was distributed to the attendees of the 2019 second COSECSA FSRC course, held in December 2019 in Kampala, Uganda. Approximately 80 people attended at least a portion of the full-day course. Forty-nine participants completed the voluntary survey questionnaire distributed to assess each session of the course at course completion. RESULTS: Ten different countries were represented among the attendees. Of the 49 evaluations, 35 respondents were male and six were female. Eight respondents did not identify a gender. Surgical residents comprised 19 of the 49 attendees, and one of the 49 attendees was a medical student. Thirty-five respondents indicated that their views of surgical research had changed after attending the course. CONCLUSIONS: The second annual FSRC at COSECSA confirmed significant interest in building research skills and partnerships in sub-Saharan Africa. A wide variety of learners attended the course, and a majority of the sessions received overwhelmingly positive feedback. Multiple conference attendees expressed interest in serving as faculty for the course moving forward, highlighting a viable path for sustainability as the Association for Academic Surgery develops an international research education platform.

Accurate survival estimates are needed for guiding cancer control efforts in sub-Saharan Africa, but previous studies have been hampered by unknown biases due to excessive loss to follow-up (LTFU). In the African Breast Cancer-Disparities in Outcomes Study, a prospective breast cancer cohort study, we implemented active mobile health follow-up, telephoning each woman or her next-of-kin (NOK) trimonthly on her mobile phone to update information on her vital status. Dates of every contact with women/NOK were analyzed from diagnosis in 2014-2017 to the earliest of September 1, 2018, death, or 3 years postdiagnosis. The cumulative incidence of being LTFU was calculated considering deaths as competing events. In all, 1,490 women were followed for a median of 24.2 (interquartile range (IQR), 14.2-34.5) months, corresponding to 8,529 successful contacts (77% of total contacts) with the women/NOK. Median time between successful contacts was 3.0 (IQR, 3.0-3.7) months. In all, 71 women (5.3%) were LTFU at 3 years: 0.8% in Nigeria, 2.2% in Namibia, and 5.6% in Uganda. Because of temporary discontinuity of active follow-up, 20.3% of women were LTFU after 2 years in Zambia. The median time to study notification of a death was 9.1 (IQR, 3.9-14.0) weeks. Although the present study was not a randomized controlled trial, in this cancer cohort with active mobile health follow-up, LTFU was much lower than in previous studies and enabled estimation of up-to-date and reliable cancer survival.

RESUMO

BACKGROUND: Greater than 80% of women presenting for breast cancer treatment in Uganda have late-stage disease, which is attributable to a dysfunctional referral system and a lack of recognition of the early signs and symptoms among primary health care providers, and compounded by the poor infrastructure and inadequate human capacity. Improving the breast health care system requires a systemic approach beginning with situational analysis to identify systematic gaps that prevent sustainable improvements in outcome. METHODS: The authors performed a situational analysis of the breast health care system using methods developed by the Breast Health Global Initiative. Based on their findings, they developed a series of recommendations for strengthening the health system for the early diagnosis of breast cancer based on clinical detection, referral, tissue sampling, and diagnosis. RESULTS: Deficits in the recognition of breast cancer signs and symptoms, the underuse of clinical breast examination as a diagnostic and/or screening tool, the centralization of diagnostic tests (radiology and pathology), reliance on excisional biopsies rather than needle biopsies, and a lack of trained professionals and knowledge of the referral system all contribute to significant health system delays. CONCLUSIONS: To strengthen referral networks and improve the early diagnosis of breast cancer in Uganda, national referral hospitals should provide educational programs to primary health care providers in community health centers (CHCs), at which the majority of women first present with symptoms. At secondary district-level facilities in which imaging and tissue sampling can be performed, the capacity for diagnostic testing could be increased through task shifting of basic interpretation (abnormal vs normal) from specialists to nonspecialists using networking technology to facilitate remote oversight from specialists at the national referral hospitals.

RESUMO

BACKGROUND: Trauma is a leading cause of morbidity and mortality in low-income countries. Improved health care systems and training are potential avenues to combat this burden. We detail a collaborative and context-specific operative trauma course taught to postgraduate surgical trainees practicing in a low-resource setting and examine its effect on resident practice. METHOD: Three classes of second year surgical residents participated in trainings from 2017 to 2019. The course was developed and taught in conjunction with local faculty. The most recent cohort logged cases before and after the course to assess resources used during initial patient evaluation and operative techniques used if the patient was taken to theater. RESULTS: Over the study period, 52 residents participated in the course. Eighteen participated in the case log study and logged 117 cases. There was no statistically significant difference in patient demographics or injury severity precourse and postcourse. Postcourse, penetrating injuries were reported less frequently (40 to 21% P < 0.05) and road traffic crashes were reported more frequently (39 to 60%, P < 0.05). There was no change in the use of bedside interventions or diagnostic imaging, besides head CT. Of patients taken for a laparotomy, there was a nonstatistically significant increase in the use of four-quadrant packing 3.4 to 21.7%) and a decrease in liver repair (20.7 to 4.3%). CONCLUSIONS: The course did not change resource utilization; however, it did influence clinical decision-making and operative techniques used during laparotomy. Additional research is indicated to evaluate sustained changes in practice patterns and clinical outcomes after operative skills training.

RESUMO

BACKGROUND: Various interventions to improve the quality of life (QoL) among slum dwellers across sub Saharan Africa have been implemented. However, the interventions impacts remain less understood. We assessed the impact of the Urban Program on Livelihoods and Income Fortification and Socio-civic Transformation (UPLIFT) project on QoL, psychological wellbeing, self-esteem, and the quality of neighbourhood social environment of young people aged 13-25 years in slum areas of Makindye and Nakawa Divisions in Kampala, Uganda. METHODS: The study was designed as a mixed method evaluation using repeated cross-sectional survey and grounded theory in both the intervention and comparison communities. The intervention effect was estimated using the difference-in-differences Kernel propensity-score matching technique, with bootstrapping. The "rcs" option was used given that data were from repeated cross-sectional surveys. A thematic analysis was adopted for the qualitative data to triangulate and complement the quantitative data. RESULTS: The UPLIFT project led to an improvement in QoL, psychological wellbeing, and self-esteem of young people. In terms of QoL, the project led to a six-percentage point increase in quality of living conditions scores (where higher scores reflect better living conditions; lower ones, worse living conditions). However, a negative effect was observed for personal independence whilst the project did not have any impact on social relations. In terms of self-esteem and psychological wellbeing, the project led to a 4.6-point increase in self-esteem scores, a 5.4-point increase in self-acceptance scores, a 5.3- point increase in purpose in life scores, a 5.7 - point increase in personal growth, and a 10.7-point increase in autonomy scores. However, the project had a negative effect on personal independence; and had no impact on environmental mastery and the quality of neighbourhood social environment. CONCLUSION: Functional community-owned assets accumulation and capacity building initiatives for young people in slum areas improved their psychological wellbeing and quality of life. However, such initiatives do not appear to address social relationships and personal independence of young people in slum areas.

RESUMO

BACKGROUND: Improving breast cancer survival in sub-Saharan Africa (SSA) is urgently needed, requiring early diagnosis and improved access to treatment. However, data on the types of and barriers to receiving breast cancer therapy in this region are limited and have not been compared between different SSA countries and treatment settings. METHODS: In different health care settings across Uganda, Nigeria and Namibian sites of the prospective African Breast Cancer - Disparities in Outcomes cohort study, we assessed the percentage of newly diagnosed breast cancer patients who received treatment (systemic, surgery and/or radiotherapy) for cancer and their socio-demographic and clinical determinants. Treatment data were systematically extracted from medical records, as well as self-reported by women during 6-month follow-up interviews, and were used to generate a binary indicator of treatment received within 12 months of diagnosis (yes/no), which was analysed via logistic regression. RESULTS: Of 1325 women, cancer treatment had not been initiated treatment within 1 year of diagnosis for 227 (17%) women and 185 (14%) of women with stage I-III disease. Untreated percentages were highest in two Nigerian regional hospitals where 38% of 314 women were not treated (32% among stage I-III). At a national referral hospital in Uganda, 18% of 430 women were not treated (15% among stage I-III). In contrast, at a cancer care centre in Windhoek, Namibia, where treatment is provided free to the patient, all non-black (100%) and almost all (98.7%) black women had initiated treatment. Percentages of untreated women were higher in women from lower socio-economic groups, women who believed in traditional medicine and, in Uganda, in HIV+ women. Self-reported treatment barriers confirmed treatment costs and treatment refusal as contributors to not receiving treatment. CONCLUSIONS: Financial support to ensure treatment access and education of treatment benefits are needed to improve treatment access for breast cancer patients across sub-Saharan Africa, especially at regional treatment centres, for lower socio-economic groups, and for the HIV-positive woman with breast cancer.

RESUMO

Breast cancer (BC) survival rates in sub-Saharan Africa (SSA) are low in part due to advanced stage at diagnosis. As one component of a study of the entire journey of SSA women with BC, we aimed to identify shared and setting-specific drivers of advanced stage BC. Women newly diagnosed in the multicountry African Breast Cancer-Disparities in Outcomes (ABC-DO) study completed a baseline interview and their stage information was extracted from medical records. Ordinal logistic regression was used to estimate odds ratios (OR) and 95% confidence intervals (CI) for advanced stage (I, II, III, IV) in relation to individual woman-level, referral and biological factors. A total of 1795 women were included from Nigeria, Uganda, Zambia, and the multiracial populations of Namibia and South Africa, 1091 of whom (61%) were stage III/IV. Stage was lower in women with greater BC knowledge (OR 0.77 (95% CI: 0.70, 0.85) per point on a 6 point scale). More advanced stage was associated with being black (4.00 (2.79, 5.74)), having attended

RESUMO

A greater understanding of the nature and drivers of poor breast cancer (BC) awareness in sub-Saharan Africa (SSA) will inform much needed awareness programmes. We aimed to assess the level and nature of BC awareness in the multi-country African Breast Cancer-Disparities in Outcome (ABC-DO) cohort of women newly diagnosed with BC during 2014-2017. Awareness indicators were assessed during a baseline interview at/near diagnosis. Logistic/ordinal regression was used to estimate odds ratios (OR) for indicators of BC awareness in relation to woman-level characteristics for individual settings and then meta-analyzed. In the 1,451 women included, almost all Namibian non-black women (n = 104) knew of BC and its curability, while in Namibian black and Zambian women, one in 7 (~ 15%) had not previously heard of BC and 25-40% did not know it was curable. In Uganda and Nigeria awareness was lowest: one in four women had no BC awareness, and 2 in 3 had no knowledge of its cure potential. Low educational level, unskilled employment, low socioeconomic position, rural residence, older age, being unmarried, and in some settings HIV-positivity, were associated with lower BC awareness-e.g., having unskilled employment was associated with not having heard of BC (summary OR 3.37; 95% confidence interval (CI) 2.17-5.23), believing that it is incurable (2.43; 1.81-3.26), and not recognizing a breast lump symptom (1.85; 1.41-2.43) but with between-setting variation (I2 > 68% for all). The findings provide evidence of the level and difference in BC awareness and beliefs across different settings, highlighting the urgent need for context-specific education programmes in the SSA region.
