A Cross-Sectional Study on Knowledge and Attitudes About Organ Donation and Transplantation in an Urban Population in a Low-Income Country.

BACKGROUND: Uganda's Health Sector Development Plan (2015/16 through 2019/2020) noted that most referrals for treatment abroad were for organ transplant services that cost the government >5.6 million USD. The government of Uganda has invested in building the capacity for organ donation and transplantation services by training human resources personnel and setting up infrastructure in Kampala, where these services can be accessed. However, there is no information on the readiness of communities and the scientific community to embrace (communities) or undertake (science) organ transplantation in the country. We set out to assess knowledge and attitudes about organ donation and transplantation among the urban population in Kampala. METHODS: We conducted a cross-sectional survey among 395 participants from the urban population of Kampala at Garden City Mall, Wandegeya market, and Nakawa market from 28 May through 7 June 2021. We asked about knowledge of organ donation and transplantation, collected sociodemographic data, and performed a sentiment analysis of participants' attitudes toward organ donation and transplantation. RESULTS: The M:F ratio of participants was 1:1; the majority (55.9%) of participants were Baganda, two-thirds of participants knew about organ donation, and 90% of participants did not know of any government policy on organ donation and transplantation. Radio/television was the most common source of information, and the kidney was the most frequently transplanted organ. Overall, there were 94.3% and 93.2% positive sentiments toward organ transplantation and organ donation, respectively. The need for stricter laws governing organ donation and transplantation, corruption, and fear were the main negative sentiments expressed by participants. CONCLUSIONS: Sensitization of the community is required regarding government policy on organ donation and transplantation, and this should be communicated through radio/television and social media. There was a positive attitude toward organ donation and transplantation.

Safety and feasibility of autologous adipose-derived stromal vascular fraction in the treatment of keloids: a phase one randomized controlled pilot trial.

INTRODUCTION: Autologous adipose-derived stromal vascular fraction (SVF) has been described to have therapeutic benefits in the treatment of keloids. However, most of the evidence on its efficacy is based on observational studies the majority of which are conducted in high-income countries and yet the highest burden of keloids is in low- and middle-income countries (LMICs). OBJECTIVES: We set out to determine the safety and feasibility of using autologous adipose derived stromal vascular fraction in the treatment of keloids in LMICs. METHODS: In this phase II randomized controlled pilot clinical trial conducted in the Plastic Surgery Unit of Kirruddu National Referral Hospital in Kampala Uganda, 8 patients were assigned a 1:1 ratio to either SVF or triamcinolone acetonide (TAC) arms. In the SVF arm, a median (Inter quartile range) amount of stromal cell infiltration of 2.7×106 (11×106) was administered, while the controls received 10 mg/ml TAC at a ratio of 1:1 TAC to keloid volume. Primary endpoints were adverse event development based on the Common Terminology Criteria for Adverse Events (CTCAE) v5.0 tool and feasibility assessment based on ≥ 70% recruitment feasibility and ≥ 80% interventional feasibility rates. RESULTS: The participants' mean age was 27.9 (±6.5) years, with a female predilection of 5 (63%). Overall, no adverse events were reported in the SVF arm, while ulceration in a single patient in the TAC arm, which was a grade II adverse event, was reported. Recruitment feasibility of 80% and interventional feasibility with 100% completion were reported. CONCLUSION: Based on our findings, an autologous adipose-derived stromal vascular fraction is feasible and safe for the treatment of keloids in LMICs.

Autologous adipose-derived stromal vascular fraction (SVF) in scar treatment among patients with keloids and hypertrophic scars: a systematic review and meta-analysis of current practices and outcomes.

BACKGROUND: Keloids and hypertrophic scars are some of the most common skin conditions globally, associated with poor treatment response and high recurrence rates. Autologous adipose-derived stromal vascular fraction (SVF) is increasingly recognized as an emerging therapy albeit limited literature on its outcome in scar treatment. This review aimed to describe the current practices and outcomes of adipose-derived stromal Vascular Fraction in scar treatment. METHODS: This systematic review assessed articles describing the use of SVF in scar treatment published between 2000 and 2023. Article searches of Medline/PubMed, Cochrane Library, and Embase databases using Mesh terms and the Boolean operators ("AND", "OR") by two independent researchers were done whilst following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Clinical studies assessing SVF in scar treatment with a primary outcome measure being an improvement in scar characteristics including the thickness, scar assessment scores were included. RESULTS: Among the 1425 studies identified in the search, 20 studies met the inclusion criteria with a total of 493 patients included. Eight of these were clinical trials with the rest being observational studies. Follow-up ranged from 3 months to 24 months. In all studies, there was an improvement in scar characteristics following single-dose treatment with SVF or its equivalent. All studies reported SVF to be safe. CONCLUSION: The review found that autologous adipose-derived SVF is a clinically effective therapy for keloids and scar treatment.

Surgical Apgar score as a predictor of outcomes in patients following laparotomy at Mulago National Referral Hospital, Uganda: a prospective cohort study.

BACKGROUND: Postoperative complications and mortality following laparotomy have remained high worldwide. Early postoperative risk stratification is essential to improve outcomes and clinical care. The surgical Apgar score (SAS) is a simple and objective bedside prediction tool that can guide a surgeon's postoperative decision making. The objective of this study was to evaluate the performance of SAS in predicting outcomes in patients undergoing laparotomy at Mulago hospital. METHOD: A prospective observational study was conducted among eligible adult patients undergoing laparotomy at Mulago hospital and followed up for 4 months. We collected data on the patient's preoperative and intraoperative characteristics. Using the data generated, SAS was calculated, and patients were classified into 3 groups namely: low (8-10), medium (5-7), and high (0-4). Primary outcomes were in-hospital major complications and mortality. Data was presented as proportions or mean (standard deviation) or median (interquartile range) as appropriate. We used inferential statistics to determine the association between the SAS and the primary outcomes while the SAS discriminatory ability was determined from the receiver-operating curve (ROC) analysis. RESULTS: Of the 151 participants recruited, 103 (68.2%) were male and the mean age was 40.6 ± 15. Overall postoperative in-hospital major complications and mortality rates were 24.2% and 10.6%, respectively. The participants with a high SAS category had an18.4 times risk (95% CI, 1.9-177, p = 0.012) of developing major complications, while those in medium SAS category had 3.9 times risk (95% CI, 1.01-15.26, p = 0.048) of dying. SAS had a fair discriminatory ability for in-hospital major complications and mortality with the area under the curve of 0.75 and 0.77, respectively. The sensitivity and specificity of SAS ≤ 6 for major complications were 60.5% and 81.14% respectively, and for death 54.8% and 81.3%, respectively. CONCLUSION: SAS of ≤ 6 is associated with an increased risk of major complications and/or mortality. SAS has a high specificity with an overall fair discriminatory ability of predicting the risk of developing in-hospital major complications and/or death following laparotomy.

The etiological spectrum of bowel obstruction and early postoperative outcome among neonates at a tertiary hospital in Uganda.

Background: Bowel obstruction is a common surgical emergency in newborns. One-fourth of neonates with obstruction suffer postoperative complications, with high mortality, especially in low-income countries. Factors attributed to mortality include prematurity, late presentation and associated multiple congenital anomalies. The prevalence and the predictors of mortality in our setting have not been well studied. We aimed to describe the early postoperative outcomes and to determine the predictors of mortality among neonates with bowel obstruction. Methods: We conducted a prospective cohort study during 4 months, when we recruited postoperative neonates from the pediatric surgery unit of Mulago Hospital. We collected data on demographics, clinical presentations, maternal characteristics, the surgical procedure performed, postoperative outcomes, etc. After follow-up for 2 weeks, we analyzed the data using Cox proportional hazards regression models of predictors of mortality. Results: A total of 76 neonates were recruited, with a male-to-female ratio of 2.2:1. The age ranged from 1 to 26 days, a median of 3 [interquartile range (IQR): 2, 7]. About 67.1% had birth weights ranging between 2.5 kg and 3.5 kg, a mean of 2.8 [standard deviation(SD)=0.64]; 76.3% were termed; with anorectal malformation (ARM), 31.6% as the leading cause, followed by jejunoileal atresia (JIA), 25%. Nearly 55.3% of neonates developed complications; 53.9% with post-operative fever, 15.8% had wound sepsis. The mortality rate was 44.7% (34/76) and was highest among cases of JIA, 41.2%. The predictors of mortality included prematurity, fever at admission, breastfeeding status, and mother's parity as well as the cadre of healthcare providers (p<0.005). Conclusions: ARM is the predominant cause of bowel obstruction among neonates, followed by JIA. The morbidity and mortality due to bowel obstruction among neonates are unacceptably high. The major predictors of mortality were prematurity, fever at admission, and the cadre of the healthcare providers.

Adipose-derived stromal vascular fraction (SVF) in scar treatment: a systematic review protocol.

BACKGROUND: Autologous adipose-derived stromal vascular fraction (SVF) is an emerging therapy that is being pioneered as a potential treatment for keloids and hypertrophic scars. Up to this point, there isn't a cure for keloids and hypertrophic scars yet they comprise the commonest benign skin disorders. Despite published studies reporting potential therapeutic benefits of SVF, their use and efficacy on scar improvement are not clearly described. The aim of this review is to describe the clinical practice involved in harvesting, processing, utilization of SVF, and associated efficacy in scar treatment. METHODS: We shall include published clinical articles evaluating the efficacy of SVF on improving scar characteristics and assessment scores among adults with keloids or hypertrophic scars. Article search of Medline/PubMed, Cochrane Library and Embase using Mesh terms of "scars" and "stromal vascular fraction" combined with the Boolean operators ("AND", "OR") will be performed by two independent researchers following the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols (PRISMA-P) statement. The primary outcome measure will be the mean difference in the Scar characteristics including Scar assessment scores, scar thickness among others. DATA SYNTHESIS: Descriptive data synthesis and mean differences between treatment arms will be calculated for the primary outcome of the scar assessment scores. In case more than three studies provide consistent characteristics of the scar assessment scores, a meta-analysis will be conducted. DISCUSSION: Evidence obtained from the systematic review will form the foundation upon which further clinical trials research will be conducted in evaluating the efficacy of autologous adipose-derived stromal vascular fraction in keloid and hypertrophic scar. The systematic review has been submitted to the PROSPERO database and is currently under review.

Incidence and risk factors of acute kidney injury in severely burned patients in Mulago Hospital, Uganda - a prospective cohort.

BACKGROUND: Acute Kidney Injury (AKI) is associated with increased mortality among severely burned patients. According to World Health Organization (WHO) 11 million people suffer from burns worldwide and burns contribute to 180,000 deaths yearly. Majority of these burns occur in the Low and Middle-Income Countries. Currently there is no published data on the incidence, risk factors and outcomes of AKI among patients with severe burns in Uganda. Early screening and treatment of patients at risk of developing AKI has been shown to improve survival. We therefore carried out a study to determine the incidence and risk factors of AKI in Uganda. METHODS: This was a prospective cohort study that consecutively included patients with severe burns admitted in Mulago National Referral Hospital burns unit between February and May 2018. Patients were followed up for 14 days and AKI was assessed according to the KIDGO criteria. The incidence of AKI was expressed as a proportion. Kaplan Meier graph was used to estimate the median survival of patients with or without AKI. The risk factors for AKI were assessed using cox proportion hazard regression analysis. RESULTS: Of the 147 patients screened, 92 met the inclusion criteria but 2 declined to participate in the study. Of the study participants, 48 (53.3%) were male, 47 (52.2%) were aged 3 years and below, the median TBSA was 17 (IQR; 13-23), 58 (69.9%) had low albumin levels and 16 (18.6%) had inhalation burns. The incidence of AKI was found to be 34.4% (95% CI; 25.9-45.9) with a mortality of 11.76% (95% CI; 6.37-20.73). Total burn surface area HR=3.10 (95% CI; 1.39 to 6.94 P=0.003) was the only independent risk factor for AKI. CONCLUSION: The incidence and mortality rate of AKI in patients with severe burns was found to be high. Having burns greater than 18% TBSA was an independent risk factor for AKI. Therefore, patients with burns greater than 18% should be assessed regularly for AKI so that treatment is instituted early should it occur.

Comparison of the PIPAS severity score tool and the QSOFA criteria for predicting in-hospital mortality of peritonitis in a tertiary hospital in Uganda: a prospective cohort study.

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.

An Early Warning Mobile Health Screening and Risk Scoring App for Preventing In-Hospital Transmission of COVID-19 by Health Care Workers: Development and Feasibility Study.

BACKGROUND: Hospitals have been identified as very high-risk places for COVID-19 transmission between health care workers and patients who do not have COVID-19. Health care workers are the most at-risk population to contract and transmit the infection, especially to already vulnerable patients who do not have COVID-19. In low-income countries, routine testing is not feasible due to the high cost of testing; therefore, presenting the risk of uncontrolled transmission within non-COVID-19 treatment wards. This challenge necessitated the development of an affordable intermediary screening tool that would enable early identification of potentially infected health care workers and for early real time DNA-polymerase chain reaction testing prioritization. This would limit the contact time of potentially infected health care workers with the patients but also enable efficient use of the limited testing kits. OBJECTIVE: The aims of this study are to describe an early warning in-hospital mobile risk analysis app for screening COVID-19 and to determine the feasibility and user-friendliness of the app among health care workers. METHODS: The primary result of this research project was the development of a mobile-based daily early warning system for in-hospital transmission of COVID-19. Overall, the Early Warning System for In-Hospital Transmission of COVID-19 (EWAS) mobile app was found to be feasible, with over 69% of the health care workers having logged more than 67% of the required times. Over 93% of the participants reported that the tool was easy to use. RESULTS: The primary result of this research project was the development of a mobile-based daily early warning system for in-hospital transmission of COVID-19. Overall, the Early Warning System for In-Hospital Transmission of COVID-19 (EWAS) mobile app was found to be feasible, with 69% of the health care workers (69/100) having logged more than 67% of the required times. Of the 100 participants, 93 reported that the tool was easy to use. CONCLUSIONS: The EWAS mobile app is a feasible and user-friendly daily risk scoring tool for preventing in-hospital transmission of COVID-19. Although it was not designed to be a diagnostic tool but rather a screening tool, there is a need to evaluate its sensitivity in predicting persons likely to have contracted COVID-19.

High rates of gastroesophageal cancers in patients with dyspepsia undergoing upper gastrointestinal endoscopy in Uganda.

Background and study aims Dyspepsia is the most common presenting symptom in the gastrointestinal clinic of Mulago National Referral hospital. The etiology is essentially not fully described in our patient population. This study was therefore conducted to establish the causes of dyspepsia based on endoscopic diagnosis among patients with dyspepsia seeking care at the National Referral hospital of Uganda. Patients and methods This retrospective study conducted in the endoscopy unit of Mulago hospital reviewed 356 patient endoscopy reports spanning January 2018 to July 2020 with a focus on those with a referral indication of dyspepsia. Age and sex were the independent variables of interest while the endoscopy findings as reported by the endoscopist were the outcome variable of interest. Results Of the 356 endoscopy reports reviewed, 159 met the inclusion criterion of dyspepsia as the indication. Participant mean age was 47.7 years (±â€Š16.53) with the majority (25.79 %) in the fifth decade while the male to female ratio was 1. The majority of patients had organic dyspepsia (90.57 %) while the commonest finding was gastritis 69 (43.4 %). Gastroesophageal cancers represented (18) 11.32 % of all findings. There was a positive association between age > 50 years with gastroesophageal cancers (7.639) as well as age < 50 years and functional dyspepsia (2.794); however, all these were not statistically significant ( P  = 0.006 and ( P  = 0.095, respectively). Conclusions Organic/structural dyspepsia comprises over 90 % of investigated dyspepsia with 11 % comprising cancer among patients seeking endoscopy at the National Referral Hospital of Uganda.

Tuberculosis as a primary cause of oesophageal stricture: a case report.

BACKGROUND: Tuberculous (TB) oesophagitis is a rare manifestation of dysphagia occurring in 0.3% of all gastro-intestinal tract TB infections as well as 0.15% of all cases of dysphagia and often is misdiagnosed. This report presents a rare manifestation of TB as a cause of oesophageal stricture. CASE PRESENTATION: We describe a rare presentation of a patient with grade IV dysphagia due to an oesophageal stricture. Oesophagoscopy revealed a pinhole stricture with evidence of high grade dysplasia on histology. Subsequently an Ivor-Lewis oesophagectomy was performed and histology revealed evidence of active oesophageal tuberculosis. The patient had an uneventful recovery and completed anti-TB medication. CONCLUSIONS: Oesophageal TB is a rare but curable cause of dysphagia. It may mimic cancer of the oesophagus and it is usually missed as a possible cause of oesophageal strictures. There needs to be an increased index of suspicion among patients with dysphagia in TB endemic regions.

Degloving injuries with versus without underlying fracture in a sub-Saharan African tertiary hospital: a prospective observational study.

BACKGROUND: Degloving injuries are surgical conditions in which an extensive portion of skin and subcutaneous tissue is detached from the underlying fasciae, muscles, or bone surface. Frequently, there is an association of fracture underlying the degloved area. We aimed to compare the short-term outcomes of degloving injuries with and without underlying fracture. METHODS: A prospective cohort study was conducted. We recruited patients with degloving injuries, and followed them up for 30 days to assess the outcomes. We collected data on socio-demography, cause and mechanism of injury, presence of underlying fracture, presence of shock at admission, injury severity score, location and size of degloving injuries, their management, and short-term outcomes. There were two comparison groups of degloving injuries based on the presence or absence of underlying fracture. We analyzed the differences between the two groups by using Fisher exact test for categorical variables and Student's t test for continuous variables; p values < 0.05 were considered to be significant. Risk ratio was calculated for the short-term outcomes. RESULTS: There were 1.56% (n = 51) of degloving injuries among 3279 admitted trauma patients during the study period of 5 months; 1% (n = 33) with and 0.56% (n = 18) without underlying fracture. For the overall degloving injuries, male-female ratio was 2 and mean age was 28.8 years; they were caused by road traffic crashes in 84%, and resulted in shock at admission in 29%. In the group with underlying fracture, lower limbs were frequently affected in 45% (p = 0.0018); serial debridement and excision of the avulsed flap were the most performed surgical procedures in 22% (p = 0.0373) and 14% (p = 0.0425), respectively; this same group had 3.9 times increased risk of developing poor outcomes (mainly infections) after 30 days and longer hospital stay (26.52 ± 31.31 days, p = 0.0472). CONCLUSION: Degloving injuries with underlying fracture are frequent in the lower limbs, and have increased risk of poor short-term outcomes and longer hospital stay. We recommend an early plastic surgery review at admission of patients with degloving injuries with underlying fracture to improve the flap viability and reduce the infection risk.

Intra-abdominal hypertension in severe burns: prevalence, incidence and mortality in a sub-Saharan African hospital.

BACKGROUND: Severe burns have been shown to be a risk factor for developing intra-abdominal hypertension (IAH). Fluid resuscitation practices used in burns management further predispose patients to intra-abdominal hypertension. The mortality associated with IAH in severe burns is estimated to be more than 74.5% once organ dysfunction occurs. Despite 95% of all burns occurring in Low and Middle income countries (LMIC), there is paucity of published data on this topic in sub-Saharan Africa. OBJECTIVES: To determine the prevalence, incidence, organ dysfunction and mortality of intra-abdominal hypertension among severe burns patients. METHODS: A prospective cohort study was conducted over a 6 months period in the Burns Unit of Mulago National Referral Hospital. Patients of all age groups with burns ≥25% and 20% in adults and children respectively were recruited and followed up for 7 days or until death occurred. Patients with burns older than 48 hours were excluded. The outcome variables were intra-abdominal pressure, organ dysfunction and seven day mortality. RESULTS: Of all the 335 burns patients admitted, 64 patients met the inclusion criteria. The overall prevalence of IAH was 57.8% while the prevalence in the children and adults was 54.5% and 61.3% respectively. The incidence of IAH was 13.1 cases/100 person days with the incidence in adults being twice that of the children. The one week mortality of patients with IAH was 82.6% with the risk of dying being 3.34 (p=0.0035) and seven day survival being less than 50%. CONCLUSION: One in two patients with severe burns exceeding 20% or 25% in children or adults respectively developed IAH. Adults had a higher prevalence and incidence of IAH. Mortality associated with IAH exceeded 80%.

Typhoid intestinal perforation: Point-of-care ultrasound as a diagnostic tool in a rural Ugandan Hospital.

INTRODUCTION: Point-of-care ultrasound (POCUS) in resource-limited areas has demonstrated utility in the hands of physicians and may be useful for non-physician providers to learn as well. CASE REPORT: An 11 year old male presented with abdominal pain and diffuse abdominal tenderness to a remote Emergency Centre (EC). An Emergency Care Practitioner, a non-physician emergency care provider with limited ultrasound training, used bedside ultrasonography and alerted the on-call surgeon of complex intraperitoneal fluid representing perforated typhoid, which expedited the patient's care. DISCUSSION: There is scant literature involving cases of non-physician use of POCUS, particularly in the emergency care setting. This case demonstrates the potential benefits of training these providers in POCUS.

INTRODUCTION: L'échographie au point de service (EPS) dans les zones à ressources limitées a démontré son utilité lorsqu'elle est effectuée par des médecins, mais son enseignement à des fournisseurs non-médecins peut également se révéler utile. CASE REPORT: Un garçon âgé de 11 ans s'est présenté avec des douleurs abdominales et une sensibilité diffuse de l'abdomen à un centre d'urgence (CU) éloigné. Un praticien de soins d'urgence, fournisseur non-médecin de soins d'urgence disposant d'une formation limitée en échographie, a utilisé l'échographie au chevet du malade et a alerté le chirurgien de garde concernant un fluide intrapéritonéal complexe caractéristique d'une performation due à la typhoïde, acélérant les soins administrés au patient. DISCUSSION: La littérature impliquant des cas d'utilisation de l'EPS par des non-médecins est peu abondante, en particulier dans le cadre des soins d'urgence. Ce cas démontre les avantages potentiels de la formation de ces fournisseurs à l'EPS.
