RESUMEN

BACKGROUND: The ability to access effective hospital care for children is a significant determinant of good health outcomes. The Western Cape is a large land area with a wide array of human settlements- both in urban and rural spaces. For many children in the Western Cape, after-hours access to healthcare becomes constrained when primary care clinics close and hospitals are either far away or difficult to get to. The cumulative travel burden of communities across this area is not known. The recently established data gathering capacity of the Provincial Health Data Centre of the Western Cape represents a new capacity to study this. OBJECTIVES: This study intends to describe the cumulative travel burdens of children in communities throughout the Western Cape, and how they compare relative to one another, with a particular focus on the after-hours period in a week. METHODS: Over a period of 5 years from 2017-2021, all the admission details to every hospital in the Western Cape of children under 18 years of age were collected, with basic demographic and disease data including place of residence. The distance each child travelled to their first admission facility was calculated and represented within defined communities across the metro of Cape Town and the rural Western Cape. RESULTS: There were 574 220 admissions over the 5-year period, of which 360 783 were able to be used for travel analysis. The majority of admissions were for children under 5 years of age, were in the City of Cape Town and occurred after hours. Median travel distance was less for children outside of Cape Town, but the range of travelled distances was greater. Communities across the Western Cape, particularly rural communities, reflected significant variation in their cumulative travel burdens. CONCLUSION: Using a large health dataset, this study demonstrates in a novel way for South Africa, the distances children travel to access admission facilities. A wide variation exists across all parts of the province, but particularly in rural areas. These findings could be further interrogated for people's choices of facility and method of travel. Detailed service area modelling and extending primary care working hours are potential considerations for improving access at scale and at the local community level.

RESUMEN

Three ΔI=1 bands with the πg_{9/2}⊗νg_{9/2} configuration have been identified in _{35}^{74}Br_{39}. Angular distribution, linear polarization, and lifetime measurements were performed to determine the multipolarity, type, mixing ratio, and absolute transition probability of the transitions. By comparing these experimental observations with the corresponding fingerprints and the quantum particle rotor model calculations, the second and third lowest bands are, respectively, suggested as the chiral partner and one-phonon wobbling excitation built on the yrast band. The evidence indicates the first chiral wobbler in nuclei.

RESUMEN

INTRODUCTION: Conflict of interests (COIs) adversely affect the integrity of science and public health. The role of medical schools in the teaching and management of COIs has been highlighted by the publication of an annual evaluation of American medical schools based on their COIs policies by the American Medical Student Association (AMSA). A deontological charter was adopted by French medical schools in 2018 but its impact on COI comprehension by students and its effects on COI prevention were not evaluated. METHODS: A 10-item direct survey was conducted among about 1000 students in Paris-Cité University in order to investigate the respect of the charter regarding COIs both in the medical school and in affiliated teaching hospitals. RESULTS: Cumulative results show a satisfying respect of prevention policies regarding COIs in the medical school and hospitals despite the fact that the existence of the charter and its major aspects were insufficiently known. Disclosure of COIs by teachers was insufficient. CONCLUSION: This first direct study among students shows better results than expected according to current non-academic surveys. Moreover, this study demonstrates the feasibility of this kind of survey whose repetition should be an appropriate tool to improve the implementation of the charter within medical schools and teaching hospitals, in particular mandatory disclosure of COIs by teachers.

RESUMEN

BACKGROUND: Routinely collected population-wide health data are often used to understand mortality trends including child mortality, as these data are often available more readily or quickly and for lower geographic levels than population-wide mortality data. However, understanding the completeness and accuracy of routine health data sources is essential for their appropriate interpretation and use. This study aims to assess the accuracy of diagnostic coding for public sector in-facility childhood (age < 5 years) infectious disease deaths (lower respiratory tract infections [LRTI], diarrhoea, meningitis, and tuberculous meningitis [TBM]) in routine hospital information systems (RHIS) through comparison with causes of death identified in a child death audit system (Child Healthcare Problem Identification Programme [Child PIP]) and the vital registration system (Death Notification [DN] Surveillance) in the Western Cape, South Africa and to calculate admission mortality rates (number of deaths in admitted patients per 1000 live births) using the best available data from all sources. METHODS: The three data sources: RHIS, Child PIP, and DN Surveillance are integrated and linked by the Western Cape Provincial Health Data Centre using a unique patient identifier. We calculated the deduplicated total number of infectious disease deaths and estimated admission mortality rates using all three data sources. We determined the completeness of Child PIP and DN Surveillance in identifying deaths recorded in RHIS and the level of agreement for causes of death between data sources. RESULTS: Completeness of recorded in-facility infectious disease deaths in Child PIP (23/05/2007-08/02/2021) and DN Surveillance (2010-2013) was 70% and 69% respectively. The greatest agreement in infectious causes of death were for diarrhoea and LRTI: 92% and 84% respectively between RHIS and Child PIP, and 98% and 83% respectively between RHIS and DN Surveillance. In-facility infectious disease admission mortality rates decreased significantly for the province: 1.60 (95% CI: 1.37-1.85) to 0.73 (95% CI: 0.56-0.93) deaths per 1000 live births from 2007 to 2020. CONCLUSION: RHIS had accurate causes of death amongst children dying from infectious diseases, particularly for diarrhoea and LRTI, with declining in-facility admission mortality rates over time. We recommend integrating data sources to ensure the most accurate assessment of child deaths.

RESUMEN

The maximum expression of hemodynamic instability during liver transplant is the so-called postreperfusion syndrome (PRS) that increases both overall mortality and postoperative complications. It was first defined by Aggarwal et al in 1987, but the results are still conflicting when establishing the relationship between PRS and acute kidney failure (AKF). We conducted a retrospective observational study of transplant recipients with deceased-donor liver grafts between January 2002 and December 2018. We analyzed the incidence of PRS and its potential negative impact over kidney function. A total of 551 transplants were analyzed. PRS was recorded in 130 patients (23.6%). The incidence of AKF was 61.5%. A total of 111 patients required kidney replacement therapy (32.7%). Regarding the severity of AKF, 128 patients were classified as acute kidney injury (AKI) 1 (23.2%), 76 as AKI 2 (13.8%), and 135 as AKI 3 (24.5%). In the group with PRS, 75.4% (n = 98) developed AKF vs 57.2% (n = 241) in the group without PRS. In the multivariate analysis we found a relationship between PRS and AKF with an odds ratio of 2.18 (95% CI, 1.30-3.64; P = .003), once adjusted by the length of the anhepatic phase, donor age, Model for End-Stage Liver Disease score, history of ascites, and need for early surgical reintervention. The incidence of AKF decreased (44.5%) ever since the implementation of delayed calcineurin inhibitors therapy and piggyback surgical technique, but a clear influence of the occurrence of PRS on the development of AKF is still observed, with an OR of 3.78 (95% CI, 1.92-7.43; P < .001), once adjusted by albumin and hemoglobin levels, Model for End-Stage Liver Disease score, and Child classification.

RESUMEN

Hemophagocytic syndrome is a rare life-threatening disorder that can be triggered by various conditions such as HIV infection and opportunistic agents. We report a case of disseminated toxoplasmosis complicated with severe hemophagocytic syndrome and revealing an unknown acquired immunodeficiency syndrome. The patient presented with multiple organ failure in intensive care unit. Once diagnosed, he benefitted from etoposide infusion, administration of specific anti-toxoplasmosis treatments and secondary antiretroviral therapy. He was alive at intensive care unit discharge and returned home with little sequalae. This case illustrates both the importance of rapid investigations of hemophagocytic syndrome etiologies in HIV positive patients and the necessity to prompt etoposide and specific treatments in order to improve potentially dramatic outcomes.

RESUMEN

BACKGROUND: Coronavirus disease (COVID-19) has imposed unprecedented stressors on South Africa (SA)'s healthcare system. Superimposed on the country's quadruple burden of disease, pandemic-related care further exposes existing inequities. Some of these inequities are specific to hospital-based inpatient services, such as the geographical maldistribution of hospital beds, lack of oxygen supplies and assisted ventilation, and scarcity of trained healthcare workers. Certain high-risk groups, such as individuals with cardiometabolic comorbidity, are likely to develop severe COVID-19 disease requiring hospitalisation with potential for a prolonged length of stay (LoS). It may be helpful for health authorities to identify those at risk for prolonged LoS to facilitate appropriate health systems planning. OBJECTIVES: To identify hospital admission laboratory parameters associated with a hospital stay >14 days in patients with COVID-19 pneumonia. METHODS: A retrospective observational study design was used. Laboratory data were obtained from an SA private laboratory for 642 inpatients with suspected or confirmed COVID-19 pneumonia, comprising 7 months of admission laboratory data from six private hospitals in Johannesburg, Gauteng Province. RESULTS: Of 642 hospital admissions for pneumonia, 497 were confirmed to have COVID-19 infection (reverse transcription-polymerase chain reaction test positive). In the COVID-19-positive group, hospital LoS was prolonged in 35.4% of admissions. Univariate analysis demonstrated an association with the following risk factors for prolonged LoS: older age; male sex; high serum creatinine, sodium (Na), chloride, potassium and urea levels and low estimated glomerular filtration rate; raised white blood cell count, lymphopenia, neutrophilia and an elevated neutrophil-to-lymphocyte ratio (NLR); and elevated levels of D-dimers, interleukin-6 (IL-6), and procalcitonin (PCT). The strongest univariate associations (relative risk (RR) ≥2.0) with a hospital stay >14 days were high Na levels, NRL >18, high PCT levels and IL-6 >40 pg/mL. On multivariable analysis, the following factors remained significantly associated with prolonged LoS: older age (RR 1.015 per year of age; 95% confidence interval (CI) 1.005 - 1.024); hypernatraemia (RR 1.80; 95% CI 1.25 - 2.60); hyperkalaemia (RR 1.61; 95% CI 1.18 - 2.20); and neutrophilia (RR 1.47; 95% CI 1.15 - 1.88). CONCLUSIONS: COVID-19 pandemic preparedness requires hospital-based inpatient care to be prioritised in resource-limited settings, and availability of beds and prompt admissions are essential to ensure good clinical outcomes. In this study of COVID-19 patients admitted with pneumonia, multivariable analysis showed older age, hypernatraemia, hyperkalaemia and neutrophilia to be associated with LoS >14 days. This may assist with healthcare systems planning.

RESUMEN

BACKGROUND:  Globally, alcohol intoxication has been shown to be significantly associated with increased risk for road traffic crash morbidity and mortality for all road users (drivers, passengers and pedestrians). This association relates to the diminished capacity of drivers while intoxicated to operate motor vehicles and the increased propensity for risk-taking behaviours. The overall prevalence of alcohol-related fatal crashes contributes significantly to the burden of disease in many countries. In South Africa, research into the relationship between alcohol intoxication and other driver risk behaviours is limited and variable, constraining appropriate and effective policy and programmatic options and interventions. OBJECTIVES:  To examine the risk for fatal crashes attributed to driver alcohol intoxication relative to speeding and other driver risk behaviours across a range of key crash and vehicle characteristics and temporal variables. METHODS:  The study used a sample of fatal crashes drawn from the Road Traffic Management Corporation database for the period 2016 - 2018, comprising 13 074 fatal crashes. An overview of the sample data is provided using descriptive statistics. Following this, logistic regression modelling was undertaken to examine and clarify the risk for alcohol-attributed fatal crashes against that for speeding and a combined category of all other driver risks using variables relating to crash complexity, vehicle characteristics and regulation, and temporal variables for day/night, weekday/weekend and vacation/non-vacation periods. RESULTS:  Compared with fatal crashes involving only the driver, the study revealed a significantly greater risk for alcohol-attributed fatal crashes in instances involving more complexity as measured by involvement of other road users (pedestrians and other drivers). Additionally, the risk for alcohol-attributed fatal crashes was significantly greater for light vehicles and buses/midibuses compared with trucks. Road users were also at greater risk for such crashes at night, over long and regular weekends, and during non-vacation periods of the year. CONCLUSIONS:  Improved enforcement to prevent alcohol intoxication using roadblocks is required in a focused manner during specific temporal periods (at night, over weekends and during non-vacation periods), while enforcement to prevent speeding and other driver risks should be prioritised during other periods using speed monitoring and mobile visible policing, respectively. There is an urgent need to improve the current measurement of alcohol attribution in fatal crashes, to ensure more accurate estimation of prevalence, and to improve analysis and understanding of the compound impact of alcohol intoxication on all other driver risk behaviours and associated fatal crashes.

RESUMEN

INTRODUCTION: In France, at the end of the sixth year of medical studies, students take a national ranking examination including progressive clinical case-based multiple-choice questions (MCQs). We aimed to evaluate the ability of these MCQs for testing higher-order thinking more than knowledge recall, and to identify their characteristics associated with success and discrimination. METHODS: We analysed the 72 progressive clinical cases taken by the students in the years 2016-2019, through an online platform. RESULTS: A total of 72 progressive clinical cases (18 for each of the 4 studied years), corresponding to 1059 questions, were analysed. Most of the clinical cases (n=43, 60%) had 15 questions. Clinical questions represented 89% of all questions, whereas basic sciences questions accounted for 9%. The most frequent medical subspecialties were internal medicine (n=90, 8%) and infectious diseases (n=88, 8%). The most frequent question types concerned therapeutics (26%), exams (19%), diagnosis (14%), and semiology (13%). Level 2 questions ("understand and apply") accounted for 59% of all questions according to the Bloom's taxonomy. The level of Bloom's taxonomy significantly changed over time with a decreasing number of level 1 questions ("remember") (P=0.04). We also analysed the results of the students among 853 questions of training ECNi. Success and discrimination significantly decreased when the number of correct answers increased (P<0.0001 both). The success, discrimination, mean score, and mean number of discrepancies did not differ according to the diagnosis, exam, imaging, semiology, or therapeutic type of questions. CONCLUSION: Progressive clinical case-based MCQs represent an innovative way to evaluate undergraduate students.

RESUMEN

INTRODUCTION: Script concordance tests (SCTs) have been developed to assess clinical reasoning in uncertain situations. Their reliability for the evaluation of undergraduate medical students has not been evaluated. METHODS: Twenty internal medicine SCT cases were implemented in undergraduate students of two programs. The results obtained on the SCTs were compared to those obtained by the same students on clinical-based classical multiple-choice questions (MCQs). RESULTS: A total of 551/883 students (62%) answered the SCTs. The mean aggregate score (based on a total 20 points) was 11.54 (3.29). The success rate and mean score for each question did not differ depending on the modal response but the discrimination rate did. The results obtained by the students on the SCT test correlated with their scores on the MCQ tests. Among students, 446/517 (86%) considered the SCTs to be more difficult than classical MCQs, although the mean score did not differ between the SCT and MCQ tests. CONCLUSION: The use of SCTs is a feasible option for the evaluation of undergraduate students. The SCT scores correlated with those obtained on classical MCQ tests.

RESUMEN

INTRODUCTION: Lemierre's syndrome is defined as an oropharyngeal infection due to Fusobacterium necrophorum, associated with septic thrombophlebitis of the internal jugular vein. The uncommon pelvic variant of the syndrome is a rare condition, poorly described in literature. CASE REPORT: We report a case of gynecological Lemierre's syndrome in a 19-year-old woman after a first sexual intercourse, who presented acute respiratory failure, left internal iliac vein thrombosis with pulmonary embolism, in the setting of salpingitis and F. necrophorum bacteriemia. CONCLUSION: Gynecological Lemierre's syndrome is a rare and unrecognized condition, which could be lethal. Early recognition of the disorder enables initiation of appropriate antibiotic therapy for 4 to 6 weeks, and discussion of anticoagulant therapy which indications are not yet well defined.

RESUMEN

INTRODUCTION: Blended-learning methods could be a response to student nonattendance. Non-compulsory teaching combining e-learning/interactive face-to-face sessions has been implemented at Paris-Diderot Medical School for the teaching of intensive care and emergency medicine during the 2018/2019 university period. The aim of the study was to assess this newly-implemented blended teaching. METHODS: Questionnaire submitted to the 388 DFASM3 medical students present at the faculty exam of intensive care/emergency medicine. Attendance at a teaching modality was defined by the follow-up of more than half of this teaching modality. Correlations between attendance at e-learning and/or interactive face-to-face sessions, and grade were performed. RESULTS: A total of 358/388 (92%) students participated in this survey. A quarter of the students (88/321 - 25%) reported they usually attended at traditional lectures. Regarding blended-learning, 210/317 (67%) students reported having attended at e-learning courses and 84/321 (27%) attended at interactive face-to-face sessions. The distribution of students according to their attendance at e-learning and/or interactive face-to-face sessions was significantly different (P<0.01). There was a significant correlation (P<0.001) between attendance at e-learning and grade obtained at the faculty exam. Nevertheless, this correlation was also found for these students in another course taught traditionally. Overall, 309/315 (98%) students were satisfied with the blended teaching, 297/318 (93%) wanted its extent to the whole medical school's curriculum. CONCLUSION: The use of combined learning methods reached more students than traditional teachings and allowed the University to focus on its role of knowledge transfer.

RESUMEN

BACKGROUND: There are increasingly more patients awaiting liver transplantation while the number of donors has remained stable. It has been proven that grafts from donors older than 60 years have comparable results with those from younger donors. It is unclear whether this is so with donors older than 80 years old. MATERIAL AND METHODS: This was a retrospective study of all adult liver transplantations at our institution between March 2011 and December 2015. We compared 1-, 3-, 6-, and 12-month graft survival rates from donors <80 years and ≥80 years. We also compared postoperative complications: infections, acute kidney injury, need for readmission in the intensive care unit, length of stay, mechanical ventilation, and specific graft complications. We considered differences in each age group regarding the presence of hepatitis C virus (HCV). RESULTS: Of 177 recipients, 38 received grafts from octogenarian donors (21.5%). Survival rates were very similar in the groups (97%, 93%, 91%, and 87% for donors <80 years and 95%, 92%, 87%, and 76% for donors ≥80 years). Although for younger grafts, 1-year survival rates were slightly lower for HCV+ patients (80% vs 89%; log-rank 0.205), this difference does not exist for elderly donors. The incidence of postoperative complications was similar in both groups. CONCLUSIONS: Livers from octogenarian donors are acceptable for liver transplantation provided that thorough assessment and selection is made by avoiding other known poor prognosis factors. The presence of HCV did not affect survival rates.

RESUMEN

BACKGROUND: Morbidity and mortality rates in orthotopic liver transplantation have decreased in the past few years. Risk factors related to severe postoperative complications, such as primary graft dysfunction, still need to be analyzed. We evaluated the influence of the hypnotic agent used during anesthesia on primary graft dysfunction. METHODS: We performed a retrospective analysis of 419 consecutive patients who received a liver transplant between 2005 and 2013 in a single center. We analyzed the incidence of primary graft dysfunction (defined as alanine aminotransferase or aspartate aminotransferase levels higher than 1500 IU/L on the first 3 days after surgery) and if the hypnotic agent was associated with this event. RESULTS: The incidence of primary graft dysfunction was 42.2% (114 patients), similar in both groups (propofol group, 89 patients, 43.2% and sevoflurane group, 25 patients, 39.1%). In the multivariate analysis, we did not find any relationship between the hypnotic agent (propofol or sevoflurane) and early graft dysfunction. CONCLUSIONS: In our patients, we found no differences in the incidence of liver graft dysfunction according to the hypnotic used during transplantation. We can suggest that both drugs (sevoflurane and propofol) are equally safe in orthotopic liver transplantation.

RESUMEN

BACKGROUND: The year 2016 will be pivotal for the evaluation of French medical students with the introduction of the first computerized National Ranking Test (ECNi). The SIDES, online electronic system for medical student evaluation, was created for this purpose. All the universities have already organized faculty exams but few a joint computerized ranking test at several universities simultaneously. We report our experience on the organization of a mock ECNi by universities Paris Descartes, Paris Diderot and Paris 13. METHODS: Docimological, administrative and technical working groups were created to organize this ECNi. Students in their fifth year of medical studies, who will be the first students to sit for the official ECNi in 2016, were invited to attend this mock exam that represented more than 50% of what will be proposed in 2016. A final electronic questionnaire allowed a docimological and organizational evaluation by students. An analysis of ratings and rankings and their distribution on a 1000-point scale were performed. RESULTS: Sixty-four percent of enrolled students (i.e., 654) attended the three half-day exams. No difference in total score and ranking between the three universities was observed. Students' feedback was extremely positive. Normalized over 1000 points, 99% of students were scored on 300 points only. Progressive clinical cases were the most discriminating test. CONCLUSION: The organization of a mock ECNi involving multiple universities was a docimological and technical success but required an important administrative, technical and teaching investment.

RESUMEN

BACKGROUND: (18)Fluor-deoxy-glucose PET-scanning of glycolytic metabolism is being used for staging in many tumors however its impact on prognosis has never been studied in breast cancer. METHODS: Glycolytic and hypoxic markers: glucose transporter (GLUT1), carbonic anhydrase IX (CAIX), monocarboxylate transporter 1 and 4 (MCT1, 4), MCT accessory protein basigin and lactate-dehydrogenase A (LDH-A) were assessed by immunohistochemistry in two cohorts of breast cancer comprising 643 node-negative and 127 triple negative breast cancers (TNBC) respectively. RESULTS: In the 643 node-negative breast tumor cohort with a median follow-up of 124 months, TNBC were the most glycolytic (≈70%), followed by Her-2 (≈50%) and RH-positive cancers (≈30%). Tumoral MCT4 staining (without stromal staining) was a strong independent prognostic factor for metastasis-free survival (HR=0.47, P=0.02) and overall-survival (HR=0.38, P=0.002). These results were confirmed in the independent cohort of 127 cancer patients. CONCLUSION: Glycolytic markers are expressed in all breast tumors with highest expression occurring in TNBC. MCT4, the hypoxia-inducible lactate/H(+) symporter demonstrated the strongest deleterious impact on survival. We propose that MCT4 serves as a new prognostic factor in node-negative breast cancer and can perhaps act soon as a theranostic factor considering the current pharmacological development of MCT4 inhibitors.
