Two Cases of Sitosterolemia Falsely Diagnosed as Familial Hypercholesterolemia: Could Digging Deeper Have Avoided Harm?

Sitosterolemia is a rare monogenic lipid disease characterized by the excessive uptake of phytosterols and their accumulation in blood and tissues. Clinically, it can present with hypercholesterolemia and xanthomas, often causing it to be misdiagnosed as familial hypercholesterolemia (FH). The diagnosis of sitosterolemia can easily be confirmed and distinguished from FH with a sterol profile and genetic investigations. Here, we report a sibship of 2 sisters with sitosterolemia initially misdiagnosed as FH. This case report illustrates the importance of considering rare conditions, such as sitosterolemia, as a differential diagnosis in patients with hypercholesterolemia, xanthomas, and hematologic anomalies. It also emphasizes the underdiagnosis of sitosterolemia and the benefits of using sterol profiles and genetic testing in the diagnostic process to initiate the appropriate therapy and avoid harm to patients.

Ethical Dilemmas Faced by Military Health Personnel During High-Intensity Conflict: The Crucial Issue of Triage.

Russia's invasion of Ukraine has triggered the biggest conflict in Europe since the Second World War. It has forced countries to prepare for engagement on a massive scale, namely, a high-intensity war between nation states. A potential massive influx of wounded personnel risks saturating logistical supply chains and requires changes to not only medical care but also a paradigm shift. In this context, the principle of distributive justice is key. The aim is to save as many lives as possible through triage, which consists in "doing the greatest good for the greatest number." This idea is fundamental, as an emergency that has passed is no longer an emergency. However, international texts and treaties not only underline that the sole criterion for triage is clinical severity, but they also fail to take into account the patient's status (civilian, friend, and foe). In a high-intensity warfare situation, these texts, and the medical-surgical triage criteria they provide are insufficient, as caregivers may be required to make decisions based on the status of the patient. The need to make such choices could cause psychological suffering among military caregivers, as individuals are recurrently faced with difficult ethical dilemmas. One way to prevent this happening is to provide predeployment training in wartime medical ethics. The latter would include both instruction in international humanitarian law and practical simulations of clinical situations where the person is faced with an ethical dilemma.

Protein hydrolysates of Moringa oleifera seed: Antioxidant and antihyperglycaemic potential as ingredient for the management of type-2 diabetes.

New plant proteins with high nutritional quality and biological properties are actively searched worldwide. Moringa oleifera seed protein isolate was prepared from defatted flour and hydrolyzed using four proteases namely trypsin, pepsin, Alcalase, and thermolysin. Then, antioxidant activity and cellular glucose uptake properties of the hydrolysates were assessed. A high degree of hydrolysis was obtained for hydrolysate prepared using trypsin (60.07%), followed by pepsin (57.14%), Alcalase (50.68%), and thermolysin (45.45%). Thermolysin hydrolysate was the most antioxidant efficient (IC50 0.15 and 0.74 mg/mL for 2,2'-azino-bis(acide 3-ethylbenzothiazoline-6-sulfonique) diammonium salt (ABTS) and 2,2-Diphenyl-1-picrylhydrazyl (DPPH) scavenging activity, respectively). Trypsin hydrolysate stimulated high glucose uptake by yeast cells (12.34-35.28%). In the absence of insulin, Alcalase hydrolysate was the most efficient for glucose uptake by the muscle, with the rate ranging from 22.03% to 29.93% after 30 min, then from 29.55% to 34.6% after 60 min. The four hydrolysates improved glucose uptake by the muscle in the presence of insulin with the rate ranging from 46.88% to 58.03% after 30 min, and from 50% to 58.18% after 60 min. Therefore, Moringa oleifera seed proteins could be used to prepare peptides as components of functional foods for the management of type-2 diabetes.

Should Soldiers Take Oral Tranexamic Acid Before Going into Battle?

ABSTRACT: Tranexamic acid is an inexpensive antifibrinolytic treatment that reduces morbidity and mortality in civilian and military trauma patients. It must be administered within 3 hours of the injury, and its efficacy is greater the earlier it is given. It is already used preventively in the civilian environment in a number of indications to reduce bleeding and bleeding-related mortality. We wondered about the potential benefits of preventive oral administration of tranexamic acid prior to an assault for military personnel with a potential risk of injury.

Prevalence of Dysbetalipoproteinemia in the UK Biobank According to Different Diagnostic Criteria.

CONTEXT: Dysbetalipoproteinemia (DBL) is a multifactorial disorder that disrupts the normal metabolism of remnant lipoproteins, causing increased risk of cardiovascular disease. However, establishing a proper diagnosis is difficult and the true prevalence of the disease in the general population remains unknown. OBJECTIVE: The objectives were to study the prevalence of the disease and to validate the performance of different clinical diagnostic criteria in a large population-based cohort. METHODS: This study included 453 437 participants from the UK Biobank. DBL was established in participants having an ε2ε2 genotype with mixed dyslipidemia or lipid-lowering therapy use (n=964). The different diagnostic criteria for DBL were applied in individuals without lipid-lowering medication (n=370 039, n=534 DBL), to compare their performance. RESULTS: Overall, 0.6% of participants had an ε2ε2 genotype, of which 36% were classified as DBL, for a disease prevalence of 0.2% (1:469). The prevalence of DBL was similar between the different genetic ancestries (≤0.2%). Several diagnostic criteria showed good sensitivity for the diagnosis of DBL (>90%), but they suffered from a very low positive predictive value (0.6%-15.4%). CONCLUSION: This study reported for the first time the prevalence of DBL in the UK Biobank according to genetic ancestry. Furthermore, we provided the first external validation of different diagnostic criteria for DBL in a large population-based cohort and highlighted the fact that these criteria should not be used to diagnose DBL alone but should rather be used as a first screening step to determine which individuals may benefit from genetic testing to confirm the diagnosis.

Acute pancreatitis risk in multifactorial chylomicronemia syndrome depends on the molecular cause of severe hypertriglyceridemia.

BACKGROUND AND AIMS: Multifactorial chylomicronemia syndrome (MCS) is a severe form of hypertriglyceridemia (hyperTG) associated with an increased risk of acute pancreatitis (AP). Severe hyperTG is mainly polygenic in nature, either caused by the presence of heterozygous pathogenic variants (PVs) in TG-related metabolism genes or by accumulation of common variants in hyperTG susceptibility genes. This study aims to determine if the risk of AP is similar amongst MCS patients with different molecular causes of severe hyperTG. METHODS: This study included 114 MCS patients who underwent genetic testing for PVs in TG-related metabolism genes and 16 single nucleotide polymorphisms (SNPs) in hyperTG susceptibility genes. A weighted TG-polygenic risk score (TG-PRS) was calculated. A TG-PRS score ≥ 90th percentile was used to define a high TG-PRS. RESULTS: Overall, 66.7% of patients had severe hyperTG of polygenic origin. MCS patients with only a PV and those with both a PV and high TG-PRS were more prone to have maximal TG concentration ≥ 40 mmol/L (OR 5.33 (1.55-18.36); p = 0.008 and OR 5.33 (1.28-22.25); p = 0.02), as well as higher prevalence of AP (OR 3.64 (0.89-14.92); p = 0.07 and OR 11.90 (2.54-55.85); p = 0.002) compared to MCS patients with high TG-PRS alone. CONCLUSIONS: This is the first study to show that MCS caused by a high TG-PRS and a PV is associated with higher risk of AP, similar to what is seen in the monogenic form of severe hyperTG. This suggests that determining the molecular cause of severe hyperTG could be useful to stratify the risk of pancreatitis in MCS.

Antithrombotic Management and Outcomes of Anterior ST-Elevation Myocardial Infarction With New-Onset Wall Motion Abnormalities in Men and Women.

Background: In patients with anterior ST-elevation myocardial infarction (STEMI) and new-onset antero-apical wall motion abnormalities (WMAs), whether the rate of prophylaxis against left ventricular thrombus and outcomes differ between men and women is unknown. Methods: A multicentre retrospective cohort study of patients with STEMI and new-onset antero-apical WMAs treated with primary percutaneous coronary intervention was conducted. Patients with an established indication of oral anticoagulation (OAC) were excluded. The rates of triple therapy (double antiplatelet therapy + OAC) at discharge were compared for women vs men. The rates of net adverse clinical events, a composite of mortality, myocardial infarction, stroke or transient ischemic attack, systemic thromboembolism or Bleeding Academic Research Consortium (BARC) type 3 or 5 bleeding at 6 months were compared across sex using a multivariate logistic regression model. Results: A total of 1664 patients were included in the primary analysis, of whom 402 (24.2%) were women and 1262 (75.8%) were men. A total of 138 women (34.3%) and 489 men (38.7%) received a triple therapy prescription at discharge (P = 0.11). At 6 months, 33 women (8.2%) and 96 men (7.6%) experienced a net adverse clinical event (adjusted odds ratio 0.82; 95% confidence interval 0.49-1.37). No difference occurred in the risk of bleeding events and ischemic events between men and women, when these were analyzed separately. Conclusions: The rates of OAC prescription for left ventricular thrombus prophylaxis and clinical outcomes at 6 months were similar in women and men following anterior STEMI with new-onset antero-apical WMAs.

Contexte: On ignore si le taux de prophylaxie contre le thrombus ventriculaire gauche et les résultats thérapeutiques diffèrent entre les hommes et les femmes qui ont subi un infarctus du myocarde avec élévation du segment ST (STEMI) antérieur et ont des anomalies du mouvement pariétal (AMP) antéroapical d'apparition récente. Méthodes: Nous avons mené une étude de cohorte rétrospective multicentrique auprès de patients qui ont subi un STEMI et ont des AMP d'apparition récente traitées par une intervention coronarienne percutanée primaire. Nous avons exclu les patients chez lesquels il existait une indication établie à l'anticoagulation orale (ACO). Nous avons comparé les taux de trithérapie (bithérapie antiplaquettaire + ACO) à la sortie de l'hôpital entre les femmes et les hommes. Nous avons comparé les taux d'événements indésirables cliniques nets, le critère composite de mortalité, d'infarctus du myocarde, d'accident vasculaire cérébral ou d'accident ischémique transitoire, la thromboembolie systémique ou l'hémorragie de type 3 ou 5 selon le Bleeding Academic Research Consortium (BARC) après 6 mois entre les sexes au moyen du modèle de régression logistique multivariée. Résultats: Au sein des 1 664 patients de l'analyse principale, 402 (24,2 %) étaient des femmes et 1262 (75,8 %) étaient des hommes. Un total de 138 femmes (34,3 %) et de 489 hommes (38,7 %) ont reçu une ordonnance de trithérapie à la sortie de l'hôpital (P = 0,11). Après 6 mois, 33 femmes (8,2 %) et 96 hommes (7,6 %) ont subi un événement indésirable net (rapport de cotes ajusté 0,82 ; intervalle de confiance à 95 % 0,49-1,37). Aucune différence n'a été notée dans le risque d'événements hémorragiques et d'événements ischémiques entre les hommes et les femmes lorsque ces événements étaient analysés séparément. Conclusions: Les taux d'ordonnances d'ACO en prophylaxie du thrombus ventriculaire gauche et les résultats cliniques après 6 mois étaient similaires entre les femmes et les hommes à la suite du STEMI antérieur et des AMP antéroapicale d'apparition récente.

Pancreatitis polygenic risk score is associated with acute pancreatitis in multifactorial chylomicronemia syndrome.

BACKGROUND: Multifactorial chylomicronemia syndrome (MCS) is a severe form of hypertriglyceridemia associated with an increased risk of acute pancreatitis (AP). The risk of AP is heterogenous and is associated with increased level of triglycerides (TG) and presence of rare variants in TG metabolism-related genes. OBJECTIVE: To determine if the accumulation of common variants in pancreatitis susceptibility genes, measured with a weighted polygenic risk score (PRS), is associated with AP in MCS patients. METHODS: A total of 114 patients with MCS underwent genetic testing for eight single nucleotide polymorphisms (SNPs) in known pancreatitis susceptibility genes (ABCG8, CLDN2, CTRB1/2, CTRC, PRSS1, PRSS2, SPINK1 and TWIST2). A weighted PRS was calculated to account for the phenotypic effect of each SNP locus. RESULTS: A high pancreatitis-PRS score (≥ 0.44) was associated with a 2.94-fold increase risk of AP (p = 0.02) among patients with MCS. MCS patients with a high pancreatitis-PRS and a rare variant in TG metabolism-related gene have a 9.50-fold increase risk of acute pancreatitis (p = 0.001), compared to those with a low-PRS and no rare variant. A multivariate analysis including the presence of rare variants, the maximal TG values and a high pancreatitis-PRS explained 26% of the variability in AP in MCS patients. CONCLUSION: This study shows for the first time that the accumulation of common variants in pancreatitis susceptibility genes is associated with AP in MCS patients. Pancreatitis-PRS could help clinicians to identify MCS patients who may be at higher risk of AP and who may benefit from more aggressive treatment.

High hsCRP concentration is associated with acute pancreatitis in multifactorial chylomicronemia syndrome.

BACKGROUND: Multifactorial chylomicronemia syndrome (MCS) is a severe form of hypertriglyceridemia (hyperTG) associated with an increased risk of acute pancreatitis (AP). However, the risk of AP is very heterogenous in MCS. Previous studies suggested that inflammation might promote disease progression in hyperTG-induced AP. OBJECTIVE: To determine if low-grade inflammation is associated with AP in MCS. METHODS: This study included 102 subjects with MCS for which high-sensitivity C-reactive protein (hsCRP) concentration was measured at their first visit at the Montreal Clinical Research Institute. RESULTS: MCS subjects with a previous history of AP had a significant higher hsCRP concentration (4.62 mg/L vs. 2.61 mg/L; p=0.003) and high hsCRP concentration (≥3mg/L) was independently associated with AP prevalence (p<0.05). Up to 64% of the variability in AP prevalence was explained by the maximal TG concentration, hsCRP concentration, the presence of rare variants in TG-related genes, and fructose intake based on a stepwise multivariate regression model (p<0.0001). CONCLUSION: This retrospective study showed for the first time that hsCRP concentration is strongly associated with AP prevalence in MCS. It also suggests that low-grade inflammation may be a driver of AP in severe hypertriglyceridemia. Prospective studies could help determine the causality of this association and assess whether medication known to reduce low-grade inflammation could help prevent AP in individuals with severe hypertriglyceridemia.

Using e-modules for acquisition of complex diabetes skills in diabetes care providers in Rwanda.

Type 1 Diabetes (T1D) is life-threatening without appropriate treatment. Though pediatric endocrinology care is limited in Rwanda, a decentralized health system allows access to local non-communicable disease (NCD) nurses through a network of 42 district hospitals. Recent rapid expansion of internet access in the country makes virtual diabetes education initiatives possible. We investigated whether Rwandan NCD nurses receiving diabetes education via online e-modules could make similar educational gains in insulin adjustment skills (IAS) compared to NCD nurses educated in a conference-style setting, and whether they would maintain equivalent competency at 1 year after education. We randomized 21 district hospitals and their NCD nurses to participate in a 1.5-day educational conference centered around care of type 1 diabetes (Group 1), while nurses from the remaining 21 hospitals (Group 2) received accommodation and access to equivalent educational materials in e-module form. Both groups were requested to review initial course materials at 4, 8, and 12 months. Ten-point IAS assessments were administered before and after education or review at each time point. Groups 1 and 2 had equal improvement after education (+2.0 vs. +2.0, p = 0.47) and equal final score at baseline (6.0 vs. 6.0, p = 0.74). However, both groups showed a diminishing improvement over time, so that any gains were lost by 4 months in Group 1 and 8 months in Group 2. Group 1 showed greater attrition in participation over time (19% vs 58% continued participation at one year, p = 0.002). Groups did not differ in subjective confidence in IAS after education. Both groups identified existing or potential access barriers to their respective educational method. While further modifications should be trialed to ensure equitable access and to maintain long-term engagement, online education is a feasible method to teach complex subspecialty skills to providers working in low-resource settings.

The 20-Year Diagnostic Odyssey of a Milder Form of Cerebrotendinous Xanthomatosis.

Tendinous xanthomas are usually a sign of genetic dyslipidemias and are said to be pathognomonic for familial hypercholesterolemia. However, the differential diagnosis must also include rarer forms of genetic dyslipidemias such as cerebrotendinous xanthomatosis (CTX). In this report, we present the diagnostic odyssey of a French-Canadian patient presenting with Achilles tendon xanthomas and an unusual mild to moderate hypercholesterolemia. Comprehensive biochemical and genetic investigations confirmed the diagnosis of CTX, 20 years after the onset of her first symptoms. We also describe a new variant in the CYP27A1 gene associated with this atypical case and expand the clinical phenotype of this rare genetic condition. CTX is thought to be underdiagnosed, and early diagnosis and treatment of this disease is essential as it has been shown to greatly improve the patient's symptoms and prognosis.

Facility-Based Indicators to Manage and Scale Up Cervical Cancer Prevention and Care Services for Women Living With HIV in Sub-Saharan Africa: a Three-Round Online Delphi Consensus Method.

BACKGROUND: Of women with cervical cancer (CC) and HIV, 85% live in sub-Saharan Africa, where 21% of all CC cases are attributable to HIV infection. We aimed to generate internationally acceptable facility-based indicators to monitor and guide scale up of CC prevention and care services offered on-site or off-site by HIV clinics. METHODS: We reviewed the literature and extracted relevant indicators, grouping them into domains along the CC control continuum. From February 2021 to March 2022, we conducted a three-round, online Delphi process to reach consensus on indicators. We invited 106 experts to participate. Through an anonymous, iterative process, participants adapted the indicators to their context (round 1), then rated them for 5 criteria on a 5-point Likert-type scale (rounds 2 and 3) and then ranked their importance (round 3). RESULTS: We reviewed 39 policies from 21 African countries and 7 from international organizations; 72 experts from 15 sub-Saharan Africa countries or international organizations participated in our Delphi process. Response rates were 34% in round 1, 40% in round 2, and 44% in round 3. Experts reached consensus for 17 indicators in the following domains: primary prevention (human papillomavirus prevention, n = 2), secondary prevention (screening, triage, treatment of precancerous lesions, n = 11), tertiary prevention (CC diagnosis and care, n = 2), and long-term impact of the program and linkage to HIV service (n = 2). CONCLUSION: We recommend that HIV clinics that offer CC control services in sub-Saharan Africa implement the 17 indicators stepwise and adapt them to context to improve monitoring along the CC control cascade.

Heat accumulation during infrared stimulation impacts the response of ex vivo rat sciatic nerve.

Infrared neural stimulation (INS) is a neuromodulation technique that involves short optical pulses delivered to the neural tissue, resulting in the initiation of action potentials. In this work, we studied the compound neural action potentials (CNAP) generated by INS in five ex vivo sciatic nerves. A 1470 nm laser emitting a sequence of 0.4 ms light pulses with a peak power of 10 W was used. A single 4 mJ stimulus is not capable of eliciting a nerve response. However, repetition of the optical stimuli resulted in the induction of CNAPs. Heat accumulation induced by repetition rates as high as 10 Hz may be involved in the increase in CNAP amplitude. This sensitization effect may help to reduce the pulse energy required to evoke CNAP. In addition, these results highlight the importance of investigating the role of the slow nerve temperature dynamics in INS.

Position: A study protocol for the prevention of fall injuries in french special forces selection courses using a body-centered intervention.

INTRODUCTION: The Military Physical and Sports Training program was developed by the French Army in order to train, optimize, and maintain individual readiness. Although the health benefits of sport practice do not need to be demonstrated, such activities can cause acute musculoskeletal injuries that need to be addressed. The prevalence of lower limb injury is rather high in the French military population and, in particular, ranges from 15 to 45% during Special Forces selection courses. Thus, this project aims to investigate the efficiency of a body-centered program designed to enhance body awareness. The program seeks to train the mind to actively pay attention to body information, while the latter is viewed as a protective factor against fall injuries. We assume: (i) that postural control can be improved by enhancing the level of body awareness; and (ii) that greater postural awareness could be beneficial in reducing the risk of fall injuries. The body-centered prevention program is based on the Optimization of the Resources of the Armed Forces (ORAF) intervention, which focuses on mental preparation and recovery, and has been deployed in the French Army for many years. METHOD AND ANALYSES: The study focuses on five French Special Forces selection courses (400 soldiers/ participants). It is divided into two stages (year 1, year 2). The first year is dedicated to data collection from the control group (200 participants), while in the second year the ORAF intervention will be deployed. In both year, participants will be subjected to the same enrollment schedule (Fig 3). The main objective is to evaluate the effectiveness of the ORAF intervention in reducing the rate of fall injuries during military selection, based on a multidisciplinary method that captures demographic, biological, biometric, clinical, and para-clinical measures. TRIAL REGISTRATION: Registration number: IDRCB number 2021-A02108-33, Clinical Trial: NCT05451394.

Burnt by His Cellphone During a Parachute Jump.

BACKGROUND: Many current cell phone (mobile phone, smartphone) batteries are lithium-ion. These batteries can overheat and catch fire under certain conditions. If it happens during a flight or air activity, this might compromise aviation safety. We report a case of a man whose phone caught fire during a parachute jump.CASE REPORT: The individual, a member of Police Special Forces, is required to regularly perform parachute jumps. During the incident flight, the man had a cell phone in a pocket that ignited during the jump. He was able to land and then extract the phone with burns requiring acute medical care and later a skin graft.DISCUSSION: This is a cautionary tale of lithium-ion batteries in flight. Many other situations could also occur with these batteries. There is little medical documentation of the risk of fire with lithium-ion batteries causing injuries during flight operations. To reduce the risk of fire, the devices should be powered down and phones should not be worn directly touching the skin. Damaged devices are more prone to overheating.des Robert V, Saint-Jean L, Corcostegui S-P, Romary E, and Derkenne C. Burnt by his cellphone during a parachute jump.

Extensive Survey and Analysis of Factors Associated with Presence of Antibodies to Orthoebolaviruses in Bats from West and Central Africa.

The seroprevalence to orthoebolaviruses was studied in 9594 bats (5972 frugivorous and 3622 insectivorous) from Cameroon, the Democratic Republic of Congo (DRC) and Guinea, with a Luminex-based serological assay including recombinant antigens of four orthoebolavirus species. Seroprevalence is expressed as a range according to different cut-off calculations. Between 6.1% and 18.9% bat samples reacted with at least one orthoebolavirus antigen; the highest reactivity was seen with Glycoprotein (GP) antigens. Seroprevalence varied per species and was higher in frugivorous than insectivorous bats; 9.1-27.5% versus 1.3-4.6%, respectively. Seroprevalence in male (13.5%) and female (14.4%) bats was only slightly different and was higher in adults (14.9%) versus juveniles (9.4%) (p < 0.001). Moreover, seroprevalence was highest in subadults (45.4%) when compared to mature adults (19.2%), (p < 0.001). Our data suggest orthoebolavirus circulation is highest in young bats. More long-term studies are needed to identify birthing pulses for the different bat species in diverse geographic regions and to increase the chances of detecting viral RNA in order to document the genetic diversity of filoviruses in bats and their pathogenic potential for humans. Frugivorous bats seem more likely to be reservoirs of orthoebolaviruses, but the role of insectivorous bats has also to be further examined.

Modulated super-Gaussian laser pulse to populate a dark rovibrational state of acetylene.

A pulse-shaping technique in the mid-infrared spectral range based on pulses with a super-Gaussian temporal profile is considered for laser control. We show a realistic and efficient path to the population of a dark rovibrational state in acetylene (C2H2). The laser-induced dynamics in C2H2 are simulated using fully experimental structural parameters. Indeed, the rotation-vibration energy structure, including anharmonicities, is defined by the global spectroscopic Hamiltonian for the ground electronic state of C2H2 built from the extensive high-resolution spectroscopy studies on the molecule, transition dipole moments from intensities, and the effects of the (inelastic) collisions that are parameterized from line broadenings using the relaxation matrix [A. Aerts, J. Vander Auwera, and N. Vaeck, J. Chem. Phys. 154, 144308 (2021)]. The approach, based on an effective Hamiltonian, outperforms today's ab initio computations both in terms of accuracy and computational cost for this class of molecules. With such accuracy, the Hamiltonian permits studying the inner mechanism of theoretical pulse shaping [A. Aerts et al., J. Chem. Phys. 156, 084302 (2022)] for laser quantum control. Here, the generated control pulse presents a number of interferences that take advantage of the control mechanism to populate the dark state. An experimental setup is proposed for in-laboratory investigation.

Determining Critical Topics for Undergraduate Surgical Education in Rwanda: Results of a Modified Delphi Process and a Consensus Conference.

Background Developing a contextually appropriate curriculum is critical to train physicians who can address surgical challenges in sub-Saharan Africa. An innovative modified Delphi process was used to identify contextually optimized curricular content to meet sub-Saharan Africa and Rwanda's surgical needs. Methods Participants were surgeons from East, Central, Southern, and West Africa and general practitioners with surgical experience. Delphi participants excluded or prioritized surgical topic areas generated from extensive grey and formal literature review. Surgical educators first screened and condensed identified topics. Round 1 screened and prioritized identified topics, with a 75% consensus cut-off based on the content validity index and a prioritization score. Topics that reached consensus were screened again in round 2 and re-prioritized, following controlled feedback. Frequencies for aggregate prioritization scores, experts in agreement, item-level content validity index, universal agreement and scale-level content validity index based on the average method (S-CVI/Ave) using proportion relevance, and intra-class correlation (ICC) (based on a mean-rating, consistency, two-way mixed-effects model) were performed. We also used arithmetic mean values and modal frequency. Cronbach's Alpha was also calculated to ascertain reliability. Results were validated through a multi-institution consensus conference attended by Rwanda-based surgical specialists, general practitioners, medical students, surgical educators, and surgical association representatives using an inclusive, participatory, collaborative, agreement-seeking, and cooperative, a priori consensus decision-making model. Results Two-hundred and sixty-seven broad surgical content areas were identified through the initial round and presented to experts. In round 2, a total of 247 (92%) content areas reached 75% consensus among 31 experts. Topics that did not achieve consensus consisted broadly of small intestinal malignancies, rare hepatobiliary pathologies, and transplantation. In the final round, 99.6% of content areas reached 75% consensus among 31 experts. The highest prioritization was on wound healing, fluid and electrolyte management, and appendicitis, followed by metabolic response, infection, preoperative preparation, antibiotics, small bowel obstruction and perforation, breast infection, acute urinary retention, testicular torsion, hemorrhoids, and surgical ethics. Overall, the consistency and average agreement between panel experts was strong. ICC was 0.856 (95% CI: 0.83-0.87). Cronbach's Alpha for round 2 was very strong (0.985, 95% CI: 0.976-0.991) and higher than round 1, demonstrating strong reliability. All 246 topics from round 4 were verbally accepted by 40 participants in open forum discussions during the consensus conference. Conclusions A modified Delphi process and consensus were able to identify essential topics to be included within a highly contextualized, locally driven surgical clerkship curriculum delivered in rural Rwanda. Other contexts can use similar processes to develop relevant curricula.

[Telehealth, what place for the advanced practice nurse?] / Télésanté, quelle place pour l'infirmier en pratique avancée ?

Remote professional practices or telehealth have been adopted by most healthcare professions around the world. Telehealth is now part of the means available to health professionals to strengthen the quality of pathways. Telehealth is not a substitute for face-to-face exercise but complements it. The relevance of a use of telehealth is the responsibility of the health professional. In this article, we specify the place of telehealth in the professional practice of an advanced practice nurse, whether in private practice or salaried by a care institution.
