TL;DR: Rheumatic heart disease patients were young, predominantly female, and had high prevalence of major cardiovascular complications, and there is suboptimal utilization of secondary antibiotic prophylaxis, oral anti-coagulation, and contraception, and variations in the use of percutaneous and surgical interventions by country income level.
Abstract: Aims Rheumatic heart disease (RHD) accounts for over a million premature deaths annually; however, there is little contemporary information on presentation, complications, and treatment.
Methods and results This prospective registry enrolled 3343 patients (median age 28 years, 66.2% female) presenting with RHD at 25 hospitals in 12 African countries, India, and Yemen between January 2010 and November 2012. The majority (63.9%) had moderate-to-severe multivalvular disease complicated by congestive heart failure (33.4%), pulmonary hypertension (28.8%), atrial fibrillation (AF) (21.8%), stroke (7.1%), infective endocarditis (4%), and major bleeding (2.7%). One-quarter of adults and 5.3% of children had decreased left ventricular (LV) systolic function; 23% of adults and 14.1% of children had dilated LVs. Fifty-five percent ( n = 1761) of patients were on secondary antibiotic prophylaxis. Oral anti-coagulants were prescribed in 69.5% ( n = 946) of patients with mechanical valves ( n = 501), AF ( n = 397), and high-risk mitral stenosis in sinus rhythm ( n = 48). However, only 28.3% ( n = 269) had a therapeutic international normalized ratio. Among 1825 women of childbearing age (12–51 years), only 3.6% ( n = 65) were on contraception. The utilization of valvuloplasty and valve surgery was higher in upper-middle compared with lower-income countries.
Conclusion Rheumatic heart disease patients were young, predominantly female, and had high prevalence of major cardiovascular complications. There is suboptimal utilization of secondary antibiotic prophylaxis, oral anti-coagulation, and contraception, and variations in the use of percutaneous and surgical interventions by country income level.

TL;DR: Among children with lactic acidosis due to severe anemia, transfusion of longer-storage compared with shorter-storage RBC units did not result in inferior reduction of elevated blood lactate levels, and these findings have relevance regarding the efficacy of stored RBC transfusion for patients with critical tissue hypoxia and lactic acids due to anemia.
Abstract: Importance Although millions of transfusions are given annually worldwide, the effect of red blood cell (RBC) unit storage duration on oxygen delivery is uncertain. Objective To determine if longer-storage RBC units are not inferior to shorter-storage RBC units for tissue oxygenation as measured by reduction in blood lactate levels and improvement in cerebral tissue oxygen saturation among children with severe anemia. Design, Setting, and Participants Randomized noninferiority trial of 290 children (aged 6-60 months), most with malaria or sickle cell disease, presenting February 2013 through May 2015 to a university-affiliated national referral hospital in Kampala, Uganda, with a hemoglobin level of 5 g/dL or lower and a lactate level of 5 mmol/L or higher. Interventions Patients were randomly assigned to receive RBC units stored 25 to 35 days (longer-storage group; n = 145) vs 1 to 10 days (shorter-storage group; n = 145). All units were leukoreduced prior to storage. All patients received 10 mL/kg of RBCs during hours 0 through 2 and, if indicated per protocol, an additional 10 mL/kg during hours 4 through 6. Main Outcomes and Measures The primary outcome was the proportion of patients with a lactate level of 3 mmol/L or lower at 8 hours using a margin of noninferiority equal to an absolute difference of 25%. Secondary measures included noninvasive cerebral tissue oxygen saturation during the first transfusion, clinical and laboratory changes up to 24 hours, and survival and health at 30 days after transfusion. Adverse events were monitored up to 24 hours. Results In the total population of 290 children, the mean (SD) presenting hemoglobin level was 3.7 g/dL (1.3) and mean lactate level was 9.3 mmol/L (3.4). Median (interquartile range) RBC unit storage was 8 days (7-9) for shorter storage vs 32 days (30-34) for longer storage without overlap. The proportion achieving the primary end point was 0.61 (95% CI, 0.52 to 0.69) in the longer-storage group vs 0.58 (95% CI, 0.49 to 0.66) in the shorter-storage group (between-group difference, 0.03 [95% CI, −0.07 to ∞], P Conclusions and Relevance Among children with lactic acidosis due to severe anemia, transfusion of longer-storage compared with shorter-storage RBC units did not result in inferior reduction of elevated blood lactate levels. These findings have relevance regarding the efficacy of stored RBC transfusion for patients with critical tissue hypoxia and lactic acidosis due to anemia.

TL;DR: House design is likely to explain some of the heterogeneity of malaria transmission in Uganda and represents a promising target for future interventions, even in highly endemic areas.
Abstract: Background: Good house construction may reduce the risk of malaria by limiting the entry of mosquito vectors. We assessed how house design may affect mosquito house entry and malaria risk in Uganda.
Methods: 100 households were enrolled in each of three sub-counties: Walukuba, Jinja district; Kihihi, Kanungu district; and Nagongera, Tororo district. CDC light trap collections of mosquitoes were done monthly in all homes. All children aged six months to ten years (n = 878) were followed prospectively for a total of 24 months to measure parasite prevalence every three months and malaria incidence. Homes were classified as modern (cement, wood or metal walls; and tiled or metal roof; and closed eaves) or traditional (all other homes).
Results: A total of 113,618 female Anopheles were collected over 6,765 nights. 6,816 routine blood smears were taken of which 1,061 (15.6%) were malaria parasite positive. 2,582 episodes of uncomplicated malaria were diagnosed after 1,569 person years of follow-up, giving an overall incidence of 1.6 episodes per person year at risk. The human biting rate was lower in modern homes than in traditional homes (adjusted incidence rate ratio (IRR) 0.48, 95% confidence interval (CI) 0.37–0.64, p<0.001). The odds of malaria infection were lower in modern homes across all the sub-counties (adjusted odds ratio 0.44, 95%CI 0.30–0.65, p<0.001), while malaria incidence was lower in modern homes in Kihihi (adjusted IRR 0.61, 95%CI 0.40–0.91, p = 0.02) but not in Walukuba or Nagongera.
Conclusions: House design is likely to explain some of the heterogeneity of malaria transmission in Uganda and represents a promising target for future interventions, even in highly endemic areas.

TL;DR: There is high prevalence of the known TB risk factors among TB patients in Kampala, Uganda, and Targeting reducing their prevalence may lead to better TB control in the country.
Abstract: Slow decline in the incidence of tuberculosis (TB) has been observed in most high TB burden countries. Knowledge of the prevalence of different TB risk factors can help expand TB control strategies. However with the exception of Human Immunodeficiency Virus (HIV) the prevalence of the other TB risk factors are poorly studied in Uganda. We aimed to determine the prevalence of different TB risk factors and TB disease presentation among TB patients in Kampala Uganda.

TL;DR: The protocol for the first known successful delivery of RRT with subsequent renal recovery in a patient with Ebola virus disease treated at Emory University Hospital, in Atlanta, Georgia is described.
Abstract: AKI has been observed in cases of Ebola virus disease. We describe the protocol for the first known successful delivery of RRT with subsequent renal recovery in a patient with Ebola virus disease treated at Emory University Hospital, in Atlanta, Georgia. Providing RRT in Ebola virus disease is complex and requires meticulous attention to safety for the patient, healthcare workers, and the community. We specifically describe measures to decrease the risk of transmission of Ebola virus disease and report pilot data demonstrating no detectable Ebola virus genetic material in the spent RRT effluent waste. This article also proposes clinical practice guidelines for acute RRT in Ebola virus disease.

TL;DR: A randomized, blinded, placebo-controlled trial of iNO at 80ppm by non-rebreather mask versus room air placebo as adjunctive treatment to artesunate in children with severe malaria was conducted as mentioned in this paper.
Abstract: Severe malaria remains a major cause of childhood mortality globally. Decreased endothelial nitric oxide is associated with severe and fatal malaria. The hypothesis was that adjunctive inhaled nitric oxide (iNO) would improve outcomes in African children with severe malaria. A randomized, blinded, placebo-controlled trial of iNO at 80 ppm by non-rebreather mask versus room air placebo as adjunctive treatment to artesunate in children with severe malaria was conducted. The primary outcome was the longitudinal course of angiopoietin-2 (Ang-2), an endothelial biomarker of malaria severity and clinical outcome. One hundred and eighty children were enrolled; 88 were assigned to iNO and 92 to placebo (all received IV artesunate). Ang-2 levels measured over the first 72 h of hospitalization were not significantly different between groups. The mortality at 48 h was similar between groups [6/87 (6.9 %) in the iNO group vs 8/92 (8.7 %) in the placebo group; OR 0.78, 95 % CI 0.26–2.3; p = 0.65]. Clinical recovery times and parasite clearance kinetics were similar (p > 0.05). Methaemoglobinaemia >7 % occurred in 25 % of patients receiving iNO and resolved without sequelae. The incidence of neurologic deficits ( 0.05). iNO at 80 ppm administered by non-rebreather mask was safe but did not affect circulating levels of Ang-2. Alternative methods of enhancing endothelial NO bioavailability may be necessary to achieve a biological effect and improve clinical outcome. Trial Registration: ClinicalTrials.gov NCT01255215

TL;DR: This work states that Africa, in particular, has a grave shortage of paediatric surgeons and there are critical shortages in workforce and skills to treat these diseases in LMICs.
Abstract: Attention to surgical conditions in lowand middle-income countries (LMICs) has increased in recent years. Because half of the population in the world’s poorest countries are children [1], paediatric surgical conditions compose a significant proportion of the global burden of disease (BoD), and there are critical shortages in workforce and skills to treat these diseases in LMICs. Several populationbased studies have highlighted the magnitude of the need for paediatric surgery and the limited capacity, both in human resources and in infrastructure, to tackle the problem [2, 3]. Africa, in particular, has a grave shortage of paediatric surgeons. The number of fully trained paediatric surgeons ranges from 1 in Malawi (population 13 million) to 120 in Egypt (population of 80 million). In more than
TL;DR: The use of blood at a tertiary care hospital is comprehensively described to inform future efforts to strengthen blood programs in resource‐limited settings.
TL;DR: Adherence to aspects of care embedded in the checklist is associated with a reduction in postoperative complications and it is necessary to make the surgical checklist available, to train the surgical team on its importance and to identify local anaesthetists to champion its implementation in East Africa.
Abstract: Mortality from anaesthesia and surgery in many countries in Sub-Saharan Africa remain at levels last seen in high-income countries 70 years ago. With many factors contributing to these poor outcomes, the World Health Organization (WHO) launched the “Safe Surgery Saves Lives” campaign in 2007. This program included the design and implementation of the “Surgical Safety Checklist”, incorporating ten essential objectives for safe surgery. We set out to determine the knowledge of and attitudes towards the use of the WHO checklist for surgical patients in national referral hospitals in East Africa. A cross-sectional survey was conducted at the main referral hospitals in Mulago (Uganda), Kenyatta (Kenya), Muhimbili (Tanzania), Centre Hospitalier Universitaire de Kigali (Rwanda) and Centre Hospitalo-Universitaire de Kamenge (Burundi). Using a pre-set questionnaire, we interviewed anaesthetists on their knowledge and attitudes towards use of the WHO surgical checklist. Of the 85 anaesthetists interviewed, only 25 % regularly used the WHO surgical checklist. None of the anaesthetists in Mulago (Uganda) or Centre Hospitalo-Universitaire de Kamenge (Burundi) used the checklist, mainly because it was not available, in contrast with Muhimbili (Tanzania), Kenyatta (Kenya), and Centre Hospitalier Universitaire de Kigali (Rwanda), where 65 %, 19 % and 36 %, respectively, used the checklist. Adherence to aspects of care embedded in the checklist is associated with a reduction in postoperative complications. It is therefore necessary to make the surgical checklist available, to train the surgical team on its importance and to identify local anaesthetists to champion its implementation in East Africa. The Ministries of Health in the participating countries need to issue directives for the implementation of the WHO checklist in all hospitals that conduct surgery in order to improve surgical outcomes.
TL;DR: Key facilitators and barriers to secondary prophylaxis for RHD from the patient perspective framed within the socioecological model are identified and direction for intervention development to improve national RHD secondary proPHylaxis is provided.
Abstract: Background Rheumatic heart disease (RHD) is the most common cause of heart disease among Ugandans age 15 to 49 years. Secondary prophylaxis with monthly injection of benzathine penicillin is effective in preventing recurrence of acute rheumatic fever and worsening of RHD, but adherence rates are poor in Uganda. Objectives This study sought to identify health behaviors, attitudes, and health care system factors that influence adherence to RHD secondary prophylaxis. Methods We conducted 5 structured focus groups with 36 participants on monthly penicillin injections for RHD in Kamplala, Uganda. Transcripts were analyzed using qualitative description analysis and health behavior models. Results Most participants were female (64%), from an urban area (81%), and had family income less than US$1 daily (69%). Ages ranged from 14 to 58 years. Median prophylaxis duration was 1.42 years and 58% were adherent (≥80% of injections). Key facilitators include perceived worsening of disease with missing injections, personal motivation, a reminder system for injections, supportive family and friends, and a positive relationship with health care providers. Barriers to adherence include lack of resources for transportation and medications, fear of injection pain, poor patient-provider communication, and poor availability of clinics and providers able to give injections. Conclusions We identified key facilitators and barriers to secondary prophylaxis for RHD from the patient perspective framed within the socioecological model. Our findings provide direction for intervention development to improve national RHD secondary prophylaxis.
TL;DR: Children with oedematous malnutrition wereLess likely to be breastfed, less likely to have HIV infection and had fewer symptoms of other infections, and no association was found with plasma levels of acute phase proteins, household food insecurity or birth weight.
Abstract: Severe acute malnutrition is a serious public health problem, and a challenge to clinicians. Why some children with malnutrition develop oedema (kwashiorkor) is not well understood. The objective of this study was to investigate socio-demographic, dietary and clinical correlates of oedema, in children hospitalised with severe acute malnutrition. We recruited children with severe acute malnutrition admitted to Mulago Hospital, Uganda. Data was collected using questionnaires, clinical examination and measurement of blood haemoglobin, plasma c-reactive protein and α1-acid glycoprotein. Correlates of oedema were identified using multiple logistic regression analysis. Of 120 children included, 77 (64%) presented with oedematous malnutrition. Oedematous children were slightly older (17.7 vs. 15.0 months, p = 0.006). After adjustment for age and sex, oedematous children were less likely to be breastfed (odds ratio (OR): 0.19, 95%-confidence interval (CI): 0.06; 0.59), to be HIV-infected (OR: 0.10, CI: 0.03; 0.41), to report cough (OR: 0.33, CI: 0.13; 0.82) and fever (OR: 0.22, CI: 0.09; 0.51), and to have axillary temperature > 37.5°C (OR: 0.28 CI: 0.11; 0.68). Household dietary diversity score was lower in children with oedema (OR: 0.58, CI: 0.40; 85). No association was found with plasma levels of acute phase proteins, household food insecurity or birth weight. Children with oedematous malnutrition were less likely to be breastfed, less likely to have HIV infection and had fewer symptoms of other infections. Dietary diversity was lower in households of children who presented with oedema. Future research may confirm whether a causal relationship exists between these factors and nutritional oedema.
TL;DR: The MCH landscape in Uganda has, for the most part, improved between 1990 and 2011, and subnational benchmarking quantified the persistence of geographic health inequalities and identified regions in need of additional health systems strengthening.
Abstract: Globally, countries are increasingly prioritizing the reduction of health inequalities and provision of universal health coverage. While national benchmarking has become more common, such work at subnational levels is rare. The timely and rigorous measurement of local levels and trends in key health interventions and outcomes is vital to identifying areas of progress and detecting early signs of stalled or declining health system performance. Previous studies have yet to provide a comprehensive assessment of Uganda’s maternal and child health (MCH) landscape at the subnational level. By triangulating a number of different data sources – population censuses, household surveys, and administrative data – we generated regional estimates of 27 key MCH outcomes, interventions, and socioeconomic indicators from 1990 to 2011. After calculating source-specific estimates of intervention coverage, we used a two-step statistical model involving a mixed-effects linear model as an input to Gaussian process regression to produce regional-level trends. We also generated national-level estimates and constructed an indicator of overall intervention coverage based on the average of 11 high-priority interventions. National estimates often veiled large differences in coverage levels and trends across Uganda’s regions. Under-5 mortality declined dramatically, from 163 deaths per 1,000 live births in 1990 to 85 deaths per 1,000 live births in 2011, but a large gap between Kampala and the rest of the country persisted. Uganda rapidly scaled up a subset of interventions across regions, including household ownership of insecticide-treated nets, receipt of artemisinin-based combination therapies among children under 5, and pentavalent immunization. Conversely, most regions saw minimal increases, if not actual declines, in the coverage of indicators that required multiple contacts with the health system, such as four or more antenatal care visits, three doses of oral polio vaccine, and two doses of intermittent preventive therapy during pregnancy. Some of the regions with the lowest levels of overall intervention coverage in 1990, such as North and West Nile, saw marked progress by 2011; nonetheless, sizeable disparities remained between Kampala and the rest of the country. Countrywide, overall coverage increased from 40 % in 1990 to 64 % in 2011, but coverage in 2011 ranged from 57 % to 70 % across regions. The MCH landscape in Uganda has, for the most part, improved between 1990 and 2011. Subnational benchmarking quantified the persistence of geographic health inequalities and identified regions in need of additional health systems strengthening. The tracking and analysis of subnational health trends should be conducted regularly to better guide policy decisions and strengthen responsiveness to local health needs.
TL;DR: In this paper, the diagnostic accuracy of the lipoarabinomannan lateral flow assay (LFA), LAM enzyme-linked immunosorbent assay (ELISA), and Xpert MTB/RIF in cerebrospinal fluid (CSF) in an autopsy cohort of Ugandan HIV-infected adults was studied.
Abstract: Point-of-care tests for tuberculous meningitis (TBM) are needed. We studied the diagnostic accuracy of the lipoarabinomannan (LAM) lateral flow assay (LFA), LAM enzyme-linked immunosorbent assay (ELISA), and Xpert MTB/RIF in cerebrospinal fluid (CSF) in an autopsy cohort of Ugandan HIV-infected adults. We obtained written informed consent postmortem from the next of kin. A complete autopsy was done and CSF obtained. We performed LAM LFA (on unprepared and supernatant CSF after heating and spinning), LAM ELISA, and Xpert MTB/RIF on the CSF samples. Accuracy parameters were calculated for histopathological TBM and also for the composite standard, including Xpert MTB/RIF-positive cases. We tested CSF of 91 patients. LAM LFA had a sensitivity of 75% for definite histopathological TBM, ELISA a sensitivity of 43%, and Xpert MTB/RIF a sensitivity of 100% and specificities of 87%, 91%, and 87%, respectively. LAM LFA had a sensitivity of 50% for definite and probable histopathological TBM, ELISA a sensitivity of 38%, and Xpert MTB/RIF a sensitivity of 86% and specificities of 70%, 91%, and 87%, respectively. LAM LFA had a sensitivity of 68% for the composite standard and ELISA a sensitivity of 48% and specificities of 78% and 98%, respectively. The rapid diagnostic tests detected TBM in 22% to 78% of patients not on anti-TB treatment. Point-of-care tests have high accuracy in diagnosis of TBM in deceased HIV-infected adults. LAM LFA in CSF is a useful additional diagnostic tool.
TL;DR: Self-efficacy was greatest among providers who had had more childbearing conversations, greater SCM awareness, perceived fewer barriers and greater intentions to counsel on TUI, and those who endorsed more stigmatizing attitudes evidenced a trend for reporting lower self- efficacy for providing SCC.
Abstract: High rates of childbearing desires (59%) and serodiscordant partnerships (50%) among people living with HIV (PHLA) in Uganda highlight the need for safer conception counseling (SCC). Provider attitudes about counseling PLHA on the use of safer conception methods (SCM) have been explored in qualitative studies, but published quantitative investigations are scarce. Data from 57 Ugandan providers were collected to examine providers' attitudes about childbearing among PLHA and engagement in discussions about childbearing, as well as their knowledge, interest, self-efficacy, and intentions to provide SCC. Correlates of self-efficacy for the provision of SCC were explored to inform the development of training programs. Providers reported a general awareness of most SCM, especially timed unprotected intercourse (TUI); but just over half felt they knew enough to counsel clients in the future and all wanted more training. Childbearing was discussed with less than a third of reproductive aged patients and was mostly initiated by patients. Most providers saw value in providing SCC and believed that most aspects of SCM would be acceptable to their clients, but numerous barriers were endorsed. Self-efficacy was greatest among providers who had had more childbearing conversations, greater SCM awareness, perceived fewer barriers and greater intentions to counsel on TUI. Providers evidence fewer stigmatizing attitudes than in the past. However, those who endorsed more stigmatizing attitudes evidenced a trend for reporting lower self-efficacy for providing SCC. Training will need to simultaneously focus on increasing providers' SCC knowledge and skills while instilling a more realistic appraisal of the risks of assisting couples to employ SCM versus doing nothing.
TL;DR: Dental caries was the most prevalent predisposing factor for pyogenic odontogenic infection and high prevalence of bacterial resistance to ampicillin and cotrimoxazole suggests the need for regular antibiotic susceptibility tests of isolates and rational use of antibiotics in the management of these infections.
Abstract: Predisposing factors of pyogenic odontogenic infection include dental caries, pericoronitis, periodontitis, trauma to the dentition and the supporting structures or complications of dental procedures. The infections are usually polymicrobial involving normal endogenous flora. We characterised pyogenic odontogenic infection in patients attending Mulago Hospital, Uganda. Of the 130 patients, 62 (47.7%) were female. The most frequently involved fascial spaces were: the buccal, 52 (25.4%); submasseteric, 46 (22.4%) and the submandibular space, 36 (17.5%). Dental caries was the most prevalent predisposing factor, particularly of the lower third molar teeth. Viridans Streptococci Group and Staphylococcus aureus were the most frequent bacterial isolates: 23.5% and 19.4%, respectively. All Viridans Streptococci isolates were resistant to penicillin G, sulfamethoxazole/trimethoprim (cotrimoxazole), ampicillin and tetracycline, but susceptible to vancomycin. All Staphylococcus aureus strains were resistant to cotrimoxazole and ampicillin while retaining susceptibility to vancomycin, cefotaxime, linezolid, moxifloxacin and amoxicillin/clavulanate. Thirty five (26.9%) patients were HIV infected and the HIV status did not significantly influence the pattern of odontogenic infection. Dental caries was the most prevalent predisposing factor for pyogenic odontogenic infection. High prevalence of bacterial resistance to ampicillin and cotrimoxazole suggests the need for regular antibiotic susceptibility tests of isolates and rational use of antibiotics in the management of these infections. Prevention requires strengthening of oral health in the community.
TL;DR: The PRIME trial in Tororo, rural Uganda, designed and tested an intervention to improve care at health centres, with the aim of reducing ill-health due to malaria in surrounding communities, with a small improvement in quality of care.
TL;DR: The prevalence of delirium in a young African population is lower than expected considering the high mortality and a history of mental illness, anaemia, sedation, endotracheal tube use, and respiratory acidosis were factors associated withDelirium.
Abstract: Aim. Delirium is common among mechanically ventilated patients in the intensive care unit (ICU). There are little data regarding delirium among mechanically ventilated patients in Africa. We sought to determine the burden of delirium and associated factors in Uganda. Methods. We conducted a multicenter prospective study among mechanically ventilated patients in Uganda. Eligible patients were screened daily for delirium using the confusional assessment method (CAM-ICU). Comparisons were made using t-test, chi-squares, and Fisher's exact test. Predictors were assessed using logistic regression. The level of statistical significance was set at P < 0.05. Results. Of 160 patients, 81 (51%) had delirium. Median time to onset of delirium was 3.7 days. At bivariate analysis, history of mental illness, sedation, multiorgan dysfunction, neurosurgery, tachypnea, low mean arterial pressure, oliguria, fevers, metabolic acidosis, respiratory acidosis, anaemia, physical restraints, marital status, and endotracheal tube use were significant predictors. At multivariable analysis, having a history of mental illness, sedation, respiratory acidosis, higher PEEP, endotracheal tubes, and anaemia predicted delirium. Conclusion. The prevalence of delirium in a young African population is lower than expected considering the high mortality. A history of mental illness, anaemia, sedation, endotracheal tube use, and respiratory acidosis were factors associated with delirium.
TL;DR: In all three countries, effective political and surgical leadership, access to country-specific surgical disease indicators, and higher domestic health expenditures are facilitating factors that promote surgical care on national health agendas.
TL;DR: The Hugh Greenwood Lecture acknowledges the extremely generous support from Mr Greenwood that has enabled the BAPS to establish funds to advance paediatric surgical training in developing countries and describes the influence that this has had on Dr Sekabira's career.
TL;DR: Open heart surgery though expensive is feasible in a developing country with increased direct funding from governments and local charities to support open heart surgeries, more cardiac patients access surgical treatment locally.
Abstract: Background: Heart disease is a disabling condition and necessary surgical intervention is often lacking in many developing countries. Training of the superspecialties abroad is largely limited to observation with little or no opportunity for hands on experience. An approach in which open heart surgeries are conducted locally by visiting teams enabling skills transfer to the local team and helps build to build capacity has been adopted at the Uganda Heart Institute (UHI). Objectives: We reviewed the progress of open heart surgery at the UHI and evaluated the postoperative outcomes and challenges faced in conducting open heart surgery in a developing country. Methods: Medical records of patients undergoing open heart surgery at the UHI from October 2007 to June 2012 were reviewed. Results: A total of 124 patients underwent open heart surgery during the study period. The commonest conditions were: venticular septal defects (VSDs) 34.7% (43/124), Atrial septal defects (ASDs) 34.7% (43/124) and tetralogy of fallot (TOF) in 10.5% (13/124). Non governmental organizations (NGOs) funded 96.8% (120/124) of the operations, and in only 4 patients (3.2%) families paid for the surgeries. There was increasing complexity in cases operated upon from predominantly ASDs and VSDs at the beginning to more complex cases like TOFs and TAPVR. The local team independently operated 19 patients (15.3%). Postoperative morbidity was low with arrhythmias, left ventricular dysfunction and re-operations being the commonest seen. Post operative sepsis occurred in only 2 cases (1.6%). The overall mortality rate was 3.2 % Conclusion: Open heart surgery though expensive is feasible in a developing country. With increased direct funding from governments and local charities to support open heart surgeries, more cardiac patients access surgical treatment locally.
TL;DR: This cross-sectional study demonstrates that microalbuminuria is highly prevalent among newly diagnosed black hypertensive patients and in the presence of LVH and there is a positive correlation between micro albuminuria and LVH among Newly diagnosed hypertensive Patients.
Abstract: Microalbuminuria is an early manifestation of kidney damage and independently predicts cardiovascular disease (CVD). Left ventricular hypertrophy (LVH) is also an early marker of cardiac manifestation of target organ damage among hypertensive patients. The prognostic significance of microalbuminuria and its correlation with left ventricular hypertrophy has not been extensively studied in African adult hypertensive populations. This study aimed at determining the prevalence of microalbuminuria, LVH in patients with microalbuminuria and the correlation between microalbuminuria and LVH among newly diagnosed black adult hypertensive patients attending a large outpatient hypertension clinic or admitted on the cardiology ward at Mulago national referral and teaching hospital and Uganda Heart Institute in Kampala, Uganda. In this cross-sectional study, 256 newly diagnosed eligible black adult hypertensive patients attending the outpatient hypertension clinic or admitted on the cardiology ward at Mulago national referral and teaching hospital and the Uganda Heart Institute, Kampala Uganda were consecutively recruited over a period of 5 months. Data on socio-demographics, clinical and laboratory findings of the study participants was collected using a pre tested questionnaire. Two spot urine samples were collected to assess for microalbuminuria. Echocardiography (ECHO) was done to assess for the left ventricular mass index using the formula of Teicholz as evidence for early hypertensive heart disease. The mean age/standard deviation of the study participants was 54.3 ± 6.2 years with a female predominance (162, 63.3 %). The prevalence of microalbuminuria among newly diagnosed hypertensive patients was 39.5 %. The prevalence of LVH among patients with microalbuminuria was found to be 17 %. There was a positive correlation between microalbuminuria and left ventricular hypertrophy among the newly diagnosed adult hypertensive patients at Mulago Hospital (r = 0.185, p = 0.003). This study demonstrates that microalbuminuria is highly prevalent among newly diagnosed black hypertensive patients and in the presence of LVH. There is also a positive correlation between microalbuminuria and LVH among newly diagnosed hypertensive patients. Since it is a less costly and readily available test, it can be used to predict presence of LVH especially in resource limited settings where ECHO services are not readily available.
TL;DR: The purpose of this study was to examine the relationship between full‐term pregnancy (FTP) and the risk of BC.
Abstract: BACKGROUND
The breast cancer (BC) risk profiles of African women differ significantly from those of women of European ancestry. African women are younger at the age of onset and tend to have high parity. The purpose of this study was to examine the relationship between full-term pregnancy (FTP) and the risk of BC.
METHODS
A case-control study was conducted among 1995 women with invasive BC and 2631 controls in Nigeria, Cameroon, and Uganda. Odds ratios (ORs) for individual ages at FTP according to the time since delivery were calculated and adjusted for confounders. A fitted spline model was used to assess the impact of the number of pregnancies on BC risk.
RESULTS
In comparison with a nulliparous woman, a parous woman with her first FTP at 20 years showed an OR of 0.76 (95% confidence interval [CI], 0.57-0.99) for developing BC in the following 5 years. Ten years later, this risk was 0.76 (95% CI, 0.58-0.99) and 0.76 (95% CI, 0.58-0.98) for women aged 25 and 30 years, respectively. Similarly, a parous woman with 1 pregnancy had an OR of 0.69 (95% CI, 0.49-0.96), whereas the OR was 0.66 (95% CI, 0.48-0.91) with 2 or 5 pregnancies and 0.67 (95% CI, 0.47-0.94) with 6 pregnancies in comparison with nulliparous women.
CONCLUSIONS
In contrast to studies in women of European ancestry, this study showed no transient increase in the risk of developing BC after FTP among African women. Further studies are needed to examine the impact of reproductive factors on early-onset BC in African women. Cancer 2015;121:2237–2243. © 2015 American Cancer Society.
TL;DR: In order to appropriately respond to need, hospital-based palliative care services in low-income settings must be of adequate size to respond to high prevalence of life-limiting illness, and to provide education and support to clinical colleagues managing all patients with life- Limiting disease.
Abstract: Background Although models of hospital-based palliative care are common in high-income countries, they are rare in low-income countries despite the high burden of progressive disease. Aim To measure the proportion of all adult and child patients admitted with previously diagnosed active life-limiting disease, who therefore may be appropriate for palliative care provision, across all beds. Design One-day 24 h census using chart review across every ward and department. Setting/participants All admitted patients at a large tertiary referral hospital in sub-Saharan Africa. Results Of 1763 reviewed patients, 663 (37.7%) had a diagnosed active life-limiting disease. Of these, 130 (19.6%) were children. The most prevalent diagnoses were HIV (41.7%), cancer (41.5%) and heart disease (9.2%). During the 24 h census period 19 patients died (population mortality rate 0.01%). Conclusions In order to appropriately respond to need, hospital-based palliative care services in low-income settings must be of adequate size to respond to high prevalence of life-limiting illness, and to provide education and support to clinical colleagues managing all patients with life-limiting disease.
TL;DR: Whilst the thyroidectomy outcomes are not equal to international standards, an acceptable standard is achievable in this resource-limited setting and extremes of thyroid size, operation duration and total thyroidectomies all have statistically poorer outcomes in this setting.
Abstract: This study aimed to document thyroidectomy outcomes in the surgical endocrine unit, Mulago Hospital, Kampala, Uganda. The burden of global surgical disease is currently receiving much attention, especially in countries experiencing epidemiological transition. There is a paucity of publications on surgical outcomes from Sub-Saharan Africa. International thyroid guidelines from high-income countries do not factor in the logistical challenges or the advanced pathology faced by the surgeon in resource-limited settings. This was a prospective cohort study in 2013. Eight peri-operative variables of poor outcome were analysed statistically against six outcomes variables. Data was collected from 0 to 6 months post-operatively. Forty-two thyroidectomies were performed over a 3-month period (female = 38). Intraoperative events recorded included rebleeding = 10 %, infection = 0 %, transient voice symptoms = 30 %, transient hypocalcaemia = 12.5 %, recurrent laryngeal nerve (RLN) paralysis = 7.5 % and permanent hypocalcaemia = 15 %. There was a weak powered association between RLN paralysis and total thyroidectomy and smaller thyroid size. There were associations between large thyroid size and both permanent hypocalcaemia and rebleeding. Younger patients showed statistically more transient voice changes compared to older patients. Older patients were statistically more likely to develop rebleeding. Shorter operative duration was associated with transient voice change, permanent hypocalcaemia and rebleeding. Airway difficulties and transient hypocalcaemia were statistically significant in prolonged procedures. Whilst the thyroidectomy outcomes are not equal to international standards, an acceptable standard is achievable in this resource-limited setting. Poor outcomes are multifactorial but extremes of thyroid size, extremes of operation duration and total thyroidectomies all have statistically poorer outcomes in this setting.
TL;DR: A descriptive, cross-sectional survey was conducted among anesthesia and surgery trainees to identify interventions that could increase production of high-quality, locally led, surgical disease research in a resource-constrained setting.
Abstract: Background: Research is critical to the training and practice of surgery and anesthesia in all settings, regardless of available resources. Unfortunately, the output of surgical and perioperative research from Africa is low. Makerere University College of Health Sciences' (MakCHS) surgical and anesthesia trainees are required to conduct research, though few publish findings or go on to pursue careers that incorporate research. We believe that early career experiences with research may greatly influence physicians' future conduct and utilization of research. We therefore sought to analyze trainee experiences and perceptions of research to identify interventions that could increase production of high-quality, locally led, surgical disease research in our resource-constrained setting. Methods: Following ethical approval, a descriptive, cross-sectional survey was conducted among anesthesia and surgery trainees using a pretested, self-administered questionnaire. Data were tabulated and frequency tables generated. Results: Of the 43 eligible trainees, 33 (77%) responded. Ninety-four percent identify research as important to career development, and 85% intend to publish their dissertations. The research dissertation is considered a financial burden by 64%. Also, 49% reported that their departments place low value on their research, and few of the findings are utilized. Trainees report that lack of protected research time, difficulty in finding research topics, and inadequate mentorship are the main challenges to conducting research projects. Discussion: Our anesthesia and surgery trainees spend considerable resources on research endeavors. Most have significant interest in incorporating research into their careers, and most intend to publish their work in peer-reviewed journals. Here we identify several challenges facing trainees including research project development, financing and mentorship. We hope to use these results to improve support in these areas for our trainees and those in other resource-limited areas.
TL;DR: There was a relatively low burden of vitamin D deficiency among patients with acute stroke in Uganda, suggesting that with increasing longevity and indoor lifestylesitamin D deficiency may assume a greater role in stroke and other cardiovascular diseases in tropical sub Saharan Africa.
Abstract: Vitamin D deficiency has been associated with acute stroke and other cardiovascular diseases in the developed world. Low 25-hydroxyvitamin D (25OHD) has been described in some populations in Sub-Saharan Africa (SSA) in spite of adequate sunshine all year round. There is no information on the magnitude of vitamin D deficiency among patients with stroke and other cardiovascular diseases in Uganda or SSA. The aim of this study was to determine the burden and characteristics of vitamin D deficiency among patients with acute stroke, the most common form of cardiovascular events in SSA. We conducted a cross-sectional study between October 2012 and March 2013. We consecutively recruited 142 subjects with acute stroke admitted to the medical wards of Mulago hospital. We administered a pre-tested questionnaire to the study participants, and did a detailed physical examination and laboratory evaluation. Serum levels of 25OHD were determined using an electrochemiluminescence assay. Data were analyzed using STATA version 12 software. The prevalence of vitamin D deficiency (25OHD < 20 ng/ml) was 15 %. Longer hours of sunshine exposure decreased the likelihood vitamin D deficiency significantly (adjusted OR 0.85, p = 0.03). Higher HDL cholesterol had a significant inverse association with vitamin D deficiency (adjusted OR 0.15, p = 0.02). In addition, the likelihood of vitamin D deficiency increased with rising age (adjusted OR 1.03, p = 0.05). There was a relatively low burden of vitamin D deficiency among patients with acute stroke in Uganda. With increasing longevity and indoor lifestyles vitamin D deficiency may assume a greater role in stroke and other cardiovascular diseases in tropical sub Saharan Africa. Future studies on the mechanisms of vitamin D deficiency and its relationship to outcomes among patients with stroke may be necessary.
