Pulmonary dimorphic fungal infections among HIV/AIDS non-TB patients with chronic cough in Kampala, Uganda.

Dimorphic fungi cause infection following the inhalation of spores into the pulmonary system. In the lower respiratory tract, the conidia transform into yeasts, which are engulfed by alveolar macrophages and may be destroyed without disease manifestation. However, in some immunocompromised individuals, they may persist and cause active fungal disease characterized by formation of granulomas in the infected tissues, which may mimic Mycobacterium tuberculosis (MTB). To determine the prevalence of pulmonary dimorphic fungal infections among HIV/AIDS patients with non-TB chronic cough at Mulago National Referral and Teaching Hospital in Kampala, Uganda. Sputum samples were collected from 175 consented HIV/AIDS patients attending the immuno-suppression syndrome (ISS) clinic at the hospital. Upon Xpert MTB/RIF sputum testing, 21 patients tested positive for MTB, and these were excluded from further analysis. The other 154 sputum negative samples were then subjected to PCR for dimorphic fungi at MBN Clinical Laboratories. Singleplex PCR was used to detect the target sequences in selected respective genes of each dimorphic fungal species of interest. DNA amplicons were detected based on gel electrophoresis. Dimorphic fungi were detected in 16.2% (25/154) of the studied population. Of these 9.1% (14/154) had Blastomyces dermatitidis and 7.1% (11/154) had Talaromyces marneffei. The remaining 84% of the studied participants had no dimorphic fungi. Histoplasma capsulatum, Coccidioides immitis and Paracoccidioides brasiliensis were not detected in any of the participants. Dimorphic fungi (B. dermatitidis and T. marneffei) were found in 16.2% of the HIV/AIDS patients with non-TB chronic cough in Kampala, Uganda. We recommend routine testing for these pathogens among HIV/AIDS patients with chronic cough.

Knowledge, Attitudes and Practices Regarding Use of Local Anaesthetics Among Non-Anaesthesia Healthcare Professionals at Mulago National Referral Hospital.

Local anaesthetics (LA) are commonly used in dental and surgical emergency wards by both anaesthesia professionals and non-anaesthesia professionals. Anecdotal evidence shows that non-anaesthesia health-care professionals do not monitor vital signs during the use of local anaesthesia, and there are no standard hospital guidelines on the use of LA and management of LA toxicity by non-anaesthesia professionals. This study sought to assess the knowledge, attitudes and practices regarding local anaesthetic use among non-anaesthesia health-care professionals at Mulago National Referral Hospital. This was a cross-sectional study that utilized a quantitative research approach. The sample size of the study was 43 non-anaesthesia healthcare professionals from the casualty and surgical outpatient wards and Mulago dental ward. Data was collected using a questionnaire and analyzed using STATA 15. Overall, 66.67% of the Specialist, 76.47% of the senior house officers, 100% of medical officers, and 80% of the clinical orthopedic house officers had unsatisfactory levels of knowledge in Mulago casualty and surgical outpatient wards. 20% of the specialist and 16.67% of the senior house officers had unsatisfactory levels of knowledge in Mulago dental ward. 87.5% of the non-anaesthesia health-care professionals do not give a test dose on a routine basis in Mulago casualty and surgical outpatient wards. A total of 63.64% of the non-anaesthesia healthcare professionals in Mulago dental ward do not sterilize the site of injection. Non-anaesthesia health-care professionals had unsatisfactory levels of knowledge, somewhat good practices, and negative attitudes toward LA use.

Hypothyroidism among children and adolescents with nephrotic syndrome in Mulago National Referral Hospital, Kampala, Uganda; a cross-sectional study

BackgroundNephrotic syndrome (NS) is the commonest glomerular disease among children. It is characterized by heavy proteinuria and is a risk factor for hypothyroidism in the affected children. Hypothyroidism is of concern because it affects the physical and intellectual development of children and adolescents. This study sought to establish the prevalence and factors associated with hypothyroidism among children and adolescents with NS.MethodsA cross-sectional design was used to study 70 children and adolescents aged 1–19 years diagnosed with nephrotic syndrome and being followed up in the kidney clinic in Mulago National Referral Hospital. Questionnaires were used to collect patients’ socio-demographics and clinical information. A blood sample was taken for analysis for thyroid stimulating hormone (TSH) and free thyroxine (FT4), renal function tests and serum albumin. Hypothyroidism included both overt and subclinical forms. Overt hypothyroidism was defined as TSH level > 10 mU/L and FT4 < 10pmol/L, or FT4 < 10pmol/l with normal TSH, or TSH < 0.5mU/l. Sub-clinical hypothyroidism was defined as TSH ranging between 5 and10 mU/L with normal age appropriate FT4 levels. Urine samples were collected and taken for a dipstick examination. The data was analyzed using STATA version 14. The Bayesian Logistic regression analysis approach was used to estimate odds ratios (OR) and their associated 95% credible intervals. All predictor variables with p value < 0.05 at frequentist statistical analysis were considered significant.ResultsThe mean age (standard deviation) of participants was 9 years (3.8). There were more males; 36 of 70 (51.4%). The prevalence of hypothyroidism was 23% (16/70 participants). Of the 16 children with hypothyroidism, 3 (18.7%) had overt hypothyroidism while 13 had subclinical hypothyroidism. Only low serum albumin was found to be strongly associated with hypothyroidism; Bayesian OR 132.57 (CI 9.13–567.10) with a frequentist OR of 37 and a p value of 0.001.ConclusionThe prevalence of hypothyroidism among children and adolescent with nephrotic syndrome attending Mulago Hospital paediatric kidney clinic was 23%. Hypoalbuminemia was found to be associated with hypothyroidism. Therefore, children and adolescents that have severely low levels of serum albumin should be screened for hypothyroidism and linked to endocrinologists for care.

Post-traumatic seizures and factors associated among adult patients with depressed skull fractures at Mulago National Referral hospital; cross-sectional study

IntroductionPost-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. ObjectiveTo determine the prevalence and factors associated with post-traumatic seizures among adult patients with DSF at Mulago National Referral hospital (MNRH). MethodsA 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. ResultsThe 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. ConclusionPatients 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.

Prevalence and Factors Associated with Anxiety Disorders Among Pregnant Women at Mulago National Referral Hospital, Uganda.

Anxiety disorders in pregnancy are common and represent a global concern. However, data regarding the magnitude of anxiety among pregnant women in Uganda are limited, and yet, these data could pave way for implementing effective mitigation measures. We determined the prevalence of anxiety disorders and associated factors among pregnant women at Mulago Hospital Uganda. A cross-sectional study was conducted among pregnant women attending antenatal care clinic at Mulago Hospital between September and November 2015. Systematic sampling was used to enroll eligible women. An interviewer-administered demographic questionnaire and the Hamilton Anxiety Rating Scale for Antenatal Anxiety (HAMA-A) scale were used to assess demographic features and anxiety, respectively. Women with HAMA-A score ≥17 were considered to have anxiety disorder. Factors associated with anxiety disorders were determined using multivariate logistic regression. A total of 501 pregnant women were enrolled into the study; the prevalence of anxiety disorders was 13% (n=65; 95% CI: 9.8-15.7%). Factors that were significantly associated with anxiety disorders were low income of the participants (adjusted odds ratio [AOR]=2.65, 95% CI: 1.16-6.06), bad relationship with spouse (AOR = 2.50, 95% CI: 1.01-5.82) and history of hypertension in previous pregnancy (AOR = 4.17, 95% CI: 1.68-10.37). Approximately one in ten women surveyed exhibited anxiety disorders. Anxiety disorders were associated with low-income levels, bad spousal relationships, and a history of hypertension during previous pregnancies. Multidisciplinary approaches that integrate mental health support, social services, and partner involvement may help address anxiety disorders in pregnancy and contribute to improved maternal and child outcomes.

Mode of birth in subsequent pregnancy when first birth was vacuum extraction or second stage cesarean section at a tertiary referral hospital in Uganda

IntroductionThe trends of increasing use of cesarean section (CS) with a decrease in assisted vaginal birth (vacuum extraction or forceps) is a major concern in health care systems all over the world, particularly in low-resource settings. Studies show that a first birth by CS is associated with an increased risk of repeat CS in subsequent births. In addition, CS compared to assisted vaginal birth (AVB), attracts higher health service costs. Resource-constrained countries have low rates of AVB compared to high-income countries. The aim of this study was to compare mode of birth in the subsequent pregnancy among women who previously gave birth by vacuum extraction or second stage CS in their first pregnancy at Mulago National Referral Hospital, Uganda.MethodsThis was a retrospective cohort study that involved interviews of 81 mothers who had a vacuum extraction or second stage CS in their first pregnancy at Mulago hospital between November 2014 to July 2015. Mode of birth in the subsequent pregnancy was compared using Chi-2 square test and a Fisher’s exact test with a 0.05 level of statistical significance.ResultsHigher rates of vaginal birth were achieved among women who had a vacuum extraction (78.4%) compared to those who had a second stage CS in their first pregnancy (38.6%), p < 0.001.Conclusions and recommendationsVacuum extraction increases a woman’s chance of having a subsequent spontaneous vaginal birth compared to second stage CS. Health professionals need to continue to offer choice of vacuum extraction in the second stage of labor among laboring women that fulfill its indication. This will help curb the up-surging rates of CS.

Equipping undergraduate medical and nursing students with elderly health care assessment skills at Makerere University, College of Health Sciences, Uganda

BackgroundElderly health care training and aging science remain the least prioritized discipline of medical education in many African countries. With scant scientific evidence on elderly health care in low-income countries, coupled with limited exposure to elderly health care training, this project aimed to equip undergraduate health professional students with elderly health care assessment skills and research through an online course and a clinical placement.MethodsStudents (3rd year) underwent online elderly health care training through the Alison courses published by the Advanced Learning Academy in Ireland. The students were then subjected to an online exam with a pass mark of 80%. Students were also trained on standard elderly health care assessment tools through a one-day session. For practical skills on data collection, each student assessed 15 elderly patients at the Mulago National Referral Hospital Assessment Centre. All tools once filled in were assessed for completion. A one-day reflection session was held with students, faculty and the project leads to share findings from the various tools used to assess elderly individuals. The students shared their experiences and provided feedback on the online training as well as the hardships they may have experienced while administering the tools. A certificate of participation was provided to the students at the end of the project.ResultsAll the students (10) gained knowledge on elderly assessment skills, the impact of aging on various body systems, and how to manage common occurrences among elderly individuals. The average score in the post-exam was 82% (standard deviation ± 2.01). All students (10) reported having had this as their first training on the assessment of functionality among elderly individuals.ConclusionsThe students gained knowledge of elderly health assessments as well as the impact of aging on various body systems. They also gained insight into how to care for the elderly holistically with an added understanding of how to manage spinal and traumatic brain injuries.

Feasibility and acceptability of undertaking postmortem studies for tuberculosis medical research in a low income country.

If we are to break new ground in difficult-to-treat or difficult-to-vaccinate diseases (such as HIV, malaria, or tuberculosis), we must have a better understanding of the immune system at the site of infection in humans. For tuberculosis (TB), the initial site of infection is the lungs, but obtaining lung tissues from subjects suffering from TB has been limited to bronchoalveolar lavage (BAL) or sputum sampling, or surgical resection of diseased lung tissue. We examined the feasibility of undertaking a postmortem study for human tuberculosis research at Mulago National Referral Hospital in Kampala, Uganda. Postmortem studies give us an opportunity to compare TB-involved and -uninvolved sites, for both diseased and non-diseased individuals. We report good acceptability of the next-of-kin to consent for their relative's tissue to be used for medical research; that postmortem and tissue processing can be undertaken within 8 hours following death; and that immune cells remain viable and functional up to 14 hours after death. Postmortem procedures remain a valuable and essential tool both to establish cause of death, and to advance our medical and scientific understanding of infectious diseases.

Safe and Effective Escalation of Evidence-Based Chemotherapy for Mature B Cell Non-Hodgkin's Lymphoma in a Low Resource Setting

BACKGROUND Although high intensity chemotherapy regimens result in &amp;gt;90% long term survival of children with Mature B-cell Non-Hodgkin Lymphoma (MB-NHL), low intensity chemotherapy regimens are used in most Sub-Sahara African (SSA) setting resulting in decades of less than 20% long term survival. This is in part because dose-intense chemotherapy strategies that are standard of care in high income countries (HIC) have not been widely or effectively implemented in low- and middle income countries (LMIC). We investigated the toxicity and outcomes of children with MB-NHL who were treated with a treatment regimen that includes 1g/M2 of methotrexate per dose (mini COPADM) at Mulago National Referral Hospital in Uganda. The objective of this study was to evaluate the safety and effectiveness of an incremental chemotherapy escalation strategy to control treatment-related toxicities and increase response and survival of children treated for MB-NHL at a pediatric oncology center in the SSA setting. METHODS We prospectively collected clinical outcomes on children under 18 years with MB-NHL at Mulago National Referral Hospital (MNRH) in Uganda between January 2020 and July 2023. Overall (OS) and event-free survival (EFS) were calculated using the Kaplan-Meier method. Events in the EFS analysis were: 1) Death; 2) Relapse; or 3) Persistent or progressive disease at the end of Cycle 3. Patients were censored at the earlier of two years from presentation or their last day of follow-up. Descriptive statistics were presented. Toxicities were graded according to Common Terminology Criteria for Adverse Events (CTCAE) version 5. RESULTS We identified 77 patients, among whom 16 (21%) died prior to commencement of the first cycle of chemotherapy and 6 (8%) treated with alternative therapies. The 55 patients who were treated with mini COPADM with 1g/M 2 of methotrexate and are included in this analysis had similar demographics and clinical phenotypes to the 22 that were excluded. The median age was 9.6 years (interquartile range ((IQR) 6.6 - 11.7 years) with 38 (69%) males. Patients were Stage III (53%, 29/55), stage IV (38%, 21/55); and 55%, (30/55) were high-risk. The most common presentations were abdominal mass 43 (78%) and jaw mass 14 (25%). With a median follow-up time of 9 months (IQR 6 - 24 months), the 1-year overall survival (OS) and event free survival (EFS) were 56%; 95% CI (41 - 76) and 41%; 95%CI (27 - 61) respectively. For children with high-risk disease, 1-year OS was 44%; 95%CI (28 - 72) and EFS 25%; 95% CI (12 - 51). Toxicities included febrile neutropenia (83%) and CTCAE grade ≥3 mucositis (44%). For the 12 patients whose cause of mortality was recorded, 1 case (8.3%) was treatment-related and 11 (91.7%) were due to cancer. CONCLUSION: This study establishes baseline response rates, survival, and toxicity for patients with pediatric MB-NHL in Uganda treated with 1g/M2 of methotrexate. Toxicities were consistent with treatment received, perhaps exacerbated by synergy of anthracycline (50 mg/m2) along with intermediate dose MTX. These findings suggest that mini-COPADM with 1g/M 2 of methotrexate can be safely supported with the current clinical resources at MNRH and this low dose regimen accounts for the poor survival of children with MB-NHL in our center. We plan to escalate our therapy to mini-COAPDM with 3g/M2 and addition of Rituximab, with contingent intensification of supportive care to curb treatment-related toxicities.

Sickle Cell Disease and Hydroxyurea Knowledge, Views and Perceptions Among 400 Sickle Cell Patients and Caregivers at Mulago Hospital Sickle Cell Clinic: A Global Health Study in Kampala, Uganda

Background: In 2017, hydroxyurea was approved for the treatment of all sickle cell patients with genotype HbSS in Uganda following overwhelming support from the NOHARM trial conducted in a malaria endemic region at Mulago National Referral Hospital's Sickle Cell Clinic. Between January 2019 and June 2022, immediately following nationwide approval and distribution of hydroxyurea, hydroxyurea was prescribed a total of 4017 (51.2%) times out of the 7851 HbSS patient visits to the clinic according to data available from the clinic. Aims:The purpose of this study is to investigate the knowledge, perceptions, and beliefs of patients with sickle cell disease and their caregivers attending this clinic in Kampala regarding their disease, complications, genetic impact, general anticipated course of treatment or natural history of disease, and hydroxyurea. Methods: A total of 400 (56%) out of 713 patients were surveyed over a 3-week period using standardized, pretested questionnaires administered orally by trained research personnel in both English (253, 63%) and Luganda (147, 36.8%), which are the most common local languages and dialects spoken by patients in Kampala. Three-hundred and twenty-one (80.3%) participants were caregivers and 79 (19.8%) were children with sickle cell disease between 12- and 17-years-old. Results: Most participants reported receiving counseling about sickle cell disease (333; 83.3%) largely by hematologists (286; 85.9%), however, several knowledge gaps were identified. Two-hundred and ninety-seven (74.3%) participants reported not knowing the type of sickle cell or genotype of the patient. Moreover, presentation of various options did not significantly improve recognition of the correct genotype, with only 121 (30.3%) participants correctly identifying HbSS. Three-hundred and twenty-eight (82%) participants correctly identified the heritable transmission of the disease from both parents; however, caregivers exhibited limited understanding of genetic risk with only 31 (9.7%) correctly identifying the one in four chances of having a subsequent child with sickle cell disease when both parents are carriers. Hydroxyurea counseling was reported by 326 (81.5%) of participants, and 307 (76.7%) participants reported that the patient received hydroxyurea, with most patients taking the medication for at least 1 year. Of the 93 (23.5%) participants who identified the patient had never received hydroxyurea, 32 (34.4%) were uncertain if the patient would be eligible and 56 (57%) believed the patient was eligible to take the medication. Participants identified hydroxyurea benefits as decreases in pain (332; 83%), hospitalization (162; 40.8%), need for blood transfusion (148; 37%), need for pain medication (87; 21.8%), infections (42; 61%), weight loss (22; 31.9%), length of hospital stay (18; 4.5%), and incidence of stroke (10; 2.5%). Slightly more than half of patients had no concerns about hydroxyurea (218; 54.5%). Most patients with concerns (182; 45.5%) identified hydroxyurea's high cost as their main concern (141; 77.5%). Other rumors and fears about hydroxyurea included: negative affects on internal organs such as the liver or kidneys (54; 29.7%), other negative side effects (27; 14.8%), inaccessibility in pharmacies and remote areas (18; 10%), harm due to stopping or missing doses (16; 8.8%), ineffectiveness (16; 8.8%), additional indications as a cancer medication (9; 4.9%), and younger children's difficulty swallowing pills (6; 3.3%). Conclusion:Given the significantly improved morbidity and mortality of sickle cell patients who are adherent to hydroxyurea, it is necessary to address the rumors, misconceptions, and gaps in understanding of the genetic impact of the disease as well as the risks and benefits of hydroxyurea therapy. At the population level, learning is impacted by education levels, literacy rates, health literacy rates, and other cultural and societal factors, thus teaching should be culturally competent and inclusive with verbal and visual methods. The high cost of the medication and lack of consistent supply seem to be the most prohibitive factors in patient acceptance and adherence to take hydroxyurea. With only 1% of Uganda's population covered by health insurance, it is imperative for system-wide changes to address the affordability and accessibility of hydroxyurea and/or to extend the coverage of health insurance to those in need.

DISP-17. BUILDING A MODEL PEDIATRIC NEURO-ONCOLOGY PROGRAM IN SUB-SAHARAN AFRICA AND ITS IMPACT

Abstract BACKGROUND Central nervous system tumors are the most common solid tumors in children and the second commonest childhood cancer globally. We describe the establishment of the first dedicated comprehensive pediatric neuro-oncology treatment center that may serve as a model for others in low-resource settings and the impact of this initiative. METHODS This is a descriptive interim report of a pediatric neuro-oncology capacity building program in the SSA setting established in March 2019 at Mulago National Referral Hospital in Uganda, including a retrospective study conducted at Mulago National referral Hospital, in patients below 18 years of age admitted with a radiological diagnosis of a brain tumor from March 2019 to March 2023, to demonstrate the impact of this program. The program is a collaboration between Makerere University, Mulago National Referral Hospital, Texas children's Hospital/Baylor College of Medicine, and other academic and philanthropy partners in North America and Europe. RESULTS A total of 14 pediatric oncologists have been trained over 6 years, with one further training in neuro-oncology. Multidisciplinary management involving local experts from Uganda and experts from Texas Children's Hospital has been strengthened. Between March 2019 and March 2023, 121 children were diagnosed radiologically with brain tumors. Majority (57%) of these patients were males. The commonest symptom at presentation was headache (42%). Most of the patients (52%) had infratentorial tumors. The commonest diagnosis was glioma (38%), craniopharyngioma (26%), medulloblastoma (11%). Fifty-two patients had surgical resection and a histological diagnosis. Ten percent of patients had no diagnosis. Radiotherapy was received by 24(20%) patients. Twenty patients received chemotherapy. Sixty-six are alive and attending clinic. The overall one-year survival was 63%(95%CI(50.3-73.4). CONCLUSION Capacity to improve the suspicion, referral, diagnosis and comprehensive care for children with central nervous system tumors in low-resource settings can be improved through innovative collaborations.

HIV Infection and 90-Day Stroke Outcomes in Uganda: A Prospective Observational Cohort Study.

Little is known about the impact of HIV infection on the clinical presentation and outcomes after stroke in the modern antiretroviral therapy (ART) era. We aimed to compare stroke characteristics and outcomes between persons with HIV (PWH) and without HIV (PWOH) presenting with stroke in Uganda. We conducted a matched cohort study at Mulago National Referral Hospital and Mbarara Regional Referral Hospital between January 2018 and November 2020. We enrolled consecutive PWH presenting with CT-confirmed acute or subacute stroke (symptom onset ≤14 days) and matched them by sex and stroke type to 2 consecutive available PWOH admitted to the same hospital. We obtained baseline clinical data and followed participants for 90 days from the day of clinical presentation. We compared stroke severity (defined by the NIH stroke scale [NIHSS]) and 90-day all-cause mortality and morbidity (using the modified Rankin Scale [mRS]) by HIV serostatus with and without adjustment for confounders. We enrolled 105 PWH and 157 PWOH with stroke. PWH were younger (mean [SD] age 49 [14] vs 59 [16] years, p < 0.001), and nearly 80% (82/105) were on ART for a median of 5 years and a median CD4 count of 214 cells/uL (interquartile range 140, 337). Compared with PWOH, PWH presented with a 3-point lower median NIHSS (16 vs 19, p = 0.011), a 20% lower proportion of all-cause mortality at 90 days (p = 0.001), and had less disability at 90 days (median mRS 4 vs 5, p = 0.004). Age and NIHSS-adjusted odds ratio of 90-day all-cause mortality in PWH compared with PWOH was 0.45 (95% CI 0.22-0.96, p = 0.037). In the modern ART era, PWH with acute stroke in Uganda present with modest stroke and are significantly less likely to die within 90 days than PWOH. This potentially reflects the protective effects of ART, enhanced health care access, and their younger age at stroke presentation.

PAEDIATRIC-09 DIAGNOSIS AND MANAGEMENT OF PEDIATRIC BRAIN TUMORS IN SUB-SAHARAN AFRICA; A CASE STUDY OF UGANDA

Abstract BACKGROUND Pediatric brain tumors are the commonest solid tumors in children and the 2nd commonest childhood cancer globally. In Sub-Saharan Africa, there is paucity of data on their diagnosis and management. OBJECTIVES To describe the presentation, investigations done, treatment modalities and outcome of pediatric patients with brain tumors seen at Mulago National Referral Hospital in Uganda from May 2019 to March 2023. METHODS A retrospective study was conducted in Mulago National Referral Hospital, pediatric oncology unit, in patients below 18 years of age, admitted with a radiological finding of a brain tumor from May 2019 to March 2023. RESULTS The total number of children treated for a brain tumor in this period was 121.Majority (69 /121 (57 %)) of patients were males. The commonest symptom at presentation was headache (42%). Brain Ct-Scans were done in all, and majority (52%) had infratentorial tumors. The commonest diagnosis was glioma (38%), craniopharyngioma (26%), medulloblastoma (11%). Fifty-two patients had surgical resection and a histological diagnosis. Ten percent of patients had no diagnosis. Only 24(20%) patients received radiotherapy. Twenty patients received chemotherapy. Sixty-six are still alive and attending clinical reviews. The overall one-year survival was 63% (95%CI (50.3.0-73.4). CONCLUSION Gliomas were the commonest diagnosed pediatric brain tumor at the Mulago National Referral Hospital, pediatric oncology unit.

OTHER-05 THE CHALLENGES IN MANAGING CHILDREN WITH PRIMARY CENTRAL NERVOUS SYSTEM TUMORS IN UGANDA

Abstract BACKGROUND Pediatric central nervous system tumors (CNS) are the second commonest childhood malignancy and the commonest solid tumor in children. Brain tumors are the commonest cause of death among all childhood cancers. OBJECTIVES To describe the challenges in managing children with CNS tumors in Uganda, treated at Mulago National Referral Hospital (MNRH) from March 2019 to March 2023, using a subset of patients with the diagnoses of medulloblastoma, pineoblastoma and ependymoma. METHODS A retrospective study was conducted in MNRH, in patients below 18 years of age, admitted with one of the three histological diagnoses. The data included time to presentation to a tertiary health center from occurrence of initial symptoms, time to surgery from time to presentation to a tertiary health center, time to a histological diagnosis from time to presentation to a tertiary health center and time to starting radiotherapy from time to presentation to a tertiary health center. RESULTS The total number of patients was 32(44% had medulloblastoma, 37% had pineoblastoma). Of 30 patients with a recorded date of occurrence of initial symptoms, the median time to presentation to a tertiary health center was 2.5 months (95% median Cl- 1.702,3,711), with the maximum at 30 months. The median time to surgery for 24 patients was 0.92 months995%Cl- 0.460, 2.143), with a maximum of 13.8 months. The median time to a histological diagnosis for 30 patients was 1.39 months (95%median Cl- 0.680, 2.163). The median time to starting radiotherapy for 16 patients was 6.5 months (95%median Cl- 3.168, 8.724) and a maximum of 23 months. The overall one-year survival for children with ependymoma was at 62.5% (95%CI- 14.2,89.3), followed by medulloblastoma at 39.5%(95%CI-12.9,65.6) and pineoblastoma at 37.45%(95%CI-9.5,67.0). CONCLUSION The management of pediatric CNS tumors in Uganda is still sub-optimal due to referral, diagnostic and treatment challenges.

Epidemiology of adverse drug reactions to antihypertensive, antithrombotic and antidiabetic medications among adult inpatients at a National Referral Hospital, Uganda

ABSTRACT Introduction Treatment for hypertension, thrombosis and type 2 diabetes mellitus is long term and usually requires a combination of drugs which increases the risk of adverse drug reactions (ADRs). This study aimed to establish the prevalence at admission, incidence during hospitalization and characteristics of ADRs linked to antihypertensive, antithrombotic and antidiabetic drugs among adult inpatients in Uganda. Methods We conducted a secondary analysis of data from a previously assembled prospective cohort study in Uganda’s Mulago National Referral Hospital. We reviewed the files of inpatients who received antihypertensive, antithrombotic and/or antidiabetic medications prior to and/or during hospitalization. The modified Schumock and Thornton Preventability Scale, the Division of AIDS Table for Grading the Severity of Adult and Paediatric Adverse Events and the World Health Organization – Uppsala Monitoring Centre seriousness criteria were used to characterize the ADRs. Results More than a quarter (27%, 42/155) of the inpatients experienced an ADR at admission or during hospitalization. The point prevalence of ADRs at admission was 8% (13/155) and the incidence of ADRs during hospitalization was 23% (36/155). Forty-one percent (35/86) of the ADRs were serious and the majority (59%, 51/86) were preventable. Conclusion One in 13 inpatients experienced an ADR on admission and one in four experienced an ADR that developed during hospitalization. Clinicians ought to prescribe medicines with lower ADR risk profile for cardiovascular and/or diabetic patients whenever possible.

Burden, risk factors, neurosurgical evacuation outcomes, and predictors of mortality among traumatic brain injury patients with expansive intracranial hematomas in Uganda: a mixed methods study design

BackgroundExpansive 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).MethodsA 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.ResultsOf 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.ConclusionEIH 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.

Perceptions about and reasons for participation in research bronchoscopy in Uganda: A qualitative analysis.

This study sought to assess perceptions towards and reasons for participation in research bronchoscopy studies in a high TB burden urban setting. Additionally, the study aimed to identify areas of pre- and post-procedural concern among healthy adults approached to participate in research bronchoscopy. A cross sectional qualitative study was undertaken at the Uganda-Case Western Reserve University Collaboration Tuberculosis Research Project Clinic at Mulago National Referral Hospital in Kampala, Uganda. In-depth interviews were conducted with participants at their pre-bronchoscopy visit (n = 17) and after they had undergone bronchoscopy (n = 23) to examine their perceptions and experiences with the procedure. Following consent, all interviews were audio recorded and later transcribed and typed in MS WORD. Local language interviews were translated into English by the social science interviewers. Qualitative analysis was performed manually following an inductive and emergent approach typical in thematic analysis. This study was approved by the Makerere University School of Social Sciences Research Ethics Committee (MAKSS REC 09.18.220) and registered with the Uganda National Council for Science and Technology (UNCST SS4785). Overall willingness to participate in bronchoscopy was high as many participants viewed the study as primarily a means of getting free health checks and determining their health status. Notably, despite extensive face to face counseling for this study coupled with the fact that our participants had been involved in prior research at the site, therapeutic misconception still played a pivotal role in willingness to participate in research bronchoscopy. Therapeutic misconception has important ethical and research implications in clinical research, which requires strategies to tackle it, even among a pool of potential participants who are knowledgeable about a disease or clinical care procedures. Continuous awareness and knowledge building about the difference between being a trial participant and therapeutic misconception must become a mainstay in trials to improve the process of informed consent for future research bronchoscopy studies.

Postpartum resolution of hypertension, proteinuria and acute kidney injury among women with preeclampsia and severe features at Mulago National Referral Hospital, Uganda: a cohort study.

The resolution of hypertension, proteinuria and AKI postpartum among women with preeclampsia is not well documented in Uganda. To determine the time to resolution of hypertension, proteinuria and AKI postpartum until 6 weeks among women with preeclampsia in Mulago Hospital, Uganda. Between August 2017 and April 2018, we measured blood pressure, urine protein and serum creatinine on days 1,7,21 and 42 postpartum among 86 women with preeclampsia. The primary outcomes were time to the resolution of hypertension, proteinuria and AKI. We fitted accelerated failure models using Stata 17's stintreg. command with a log normal distribution and obtained time ratios of selected exposures on time to resolution of hypertension, proteinuria and AKI intervals. The median time to resolution of hypertension, proteinuria and AKI was seven (7) days (Inter quartile range, IQR 1-21). The time to resolution of hypertension among primiparous women was 3.5 times that of multiparous women [TR 3.5, 95%CI 1.1, 11.3]. No differences were observed in resolution of hypertension, proteinuria and acute kidney injury. The time to resolution of hypertension, proteinuria and AKI was seven days. We recommend larger studies with longer follow-up beyond six-weeks postpartum to inform revision of our guidelines.

Delay in healthcare seeking for young children with severe pneumonia at Mulago National Referral Hospital, Uganda: A mixed methods cross-sectional study.

Globally, pneumonia is the leading infectious cause of under-five mortality, and this can be reduced by prompt healthcare seeking. Data on factors associated with delays in seeking care for children with pneumonia in Uganda is scarce. The study aimed to determine the prevalence, factors associated with delay, barriers, and facilitators of prompt healthcare seeking for children under five years of age with severe pneumonia attending Mulago National Referral Hospital (MNRH) Uganda. A mixed methods cross-sectional study was conducted among 384 caregivers of children with severe pneumonia at MNRH. Quantitative data was collected using interviewer-administered structured questionnaires and qualitative data through focus group discussions with caregivers. Descriptive statistics were used to determine the prevalence of delay in care seeking. Logistic regression analysis was used to determine the factors that were independently associated with delay in seeking healthcare. Content thematic analysis was used to analyze for barriers and facilitators of prompt healthcare seeking. The prevalence of delay in seeking healthcare was 53.6% (95% CI: 48.6-58.6). Long distance to a hospital (AOR = 1.94, 95% CI 1.22-3.01, p value = 0.003), first seeking care elsewhere (AOR = 3.33, 95% CI 1.85-6.01, p value = 0.001), and monthly income ≤100,000 UGX (28 USD) (AOR = 2.27,95% CI 1.33-3.86, p value = 0.003) were independently associated with delay in seeking healthcare. Limited knowledge of symptoms, delayed referrals, self-medication, and low level of education were barriers to prompt healthcare seeking while recognition of symptoms of severe illness in the child, support from spouses, and availability of money for transport were key facilitators of early healthcare seeking. This study showed that more than half of the caregivers delayed seeking healthcare for their children with pneumonia symptoms. Caregivers who first sought care elsewhere, lived more than 5 km from the hospital, and earned less than 28 USD per month were more likely to delay seeking healthcare for their children with severe pneumonia. Limited knowledge of symptoms of pneumonia, self-medication, and delayed referral hindered prompt care-seeking. Key facilitators of prompt care-seeking were accessibility to health workers, support from spouses, and recognition of symptoms of severe illness in children. There is a need for programs that educate caregivers about pneumonia symptoms, in children less than five years.

“We felt so proud by the president calling us my heroes.” An exploration of the nurse’s experiences in the management of COVID-19 patients in Uganda

IntroductionAdequate and intensive nursing care was a key characteristic of recovery of the COVID-19 patients globally and in Uganda. However, there is limited literature on the experiences of nurses who participated in the care of COVID-19 patients in Uganda, East Africa, and Africa at large, yet imperative in designing approaches to increase the efficiency of the health systems’ response to future pandemics. To address this gap, this study aimed to explore the experiences of the nurses who managed COVID-19 patients at Mulago National Referral Hospital in Uganda.MethodsThis was an exploratory qualitative study that used purposive sampling to identify 21 nurses who treated COVID-19 patients at Mulago National Referral Hospital in Uganda. Focus Group Discussions were used to collect data. Thematic Analysis was used to analyze the data. Common codes were identified and grouped to create subthemes and major themes.ResultsSix themes were identified: 1) Motivation to work on COVID-19 patients, 2 ) Roles performed by nurses, 3) High workload and professional role strain, 4) Challenges with maintaining personal health and relationships, 5) Institutional and government support, 6) Acquired professional knowledge and skills to manage critical patients and epidemics. Most of the nurses faced work burnout, social isolation, stress, and psychological trauma. However, interprofessional collaboration, financial incentives, government recognition, and provision of personal protective equipment, were key motivators for the nurses. The majority reported to have gained new knowledge and skills in the management of pandemics and highly infectious diseases.ConclusionThe nurses experienced negative scenarios like work burnout due to high workload, social isolation, and psychological stress. Therefore, there is a need for health systems to develop approaches and policies that support nurses’ well-being. Nevertheless, key attributes like resilience, adaptability, and diligence to serve enabled them to persevere despite the hardships faced.
