Training first-year medical residents to break bad news using healthcare role-play and trainees as simulated patients: Experience of the "ADIAMED" program from Lille University School of Medicine.

INTRODUCTION: Several studies suggest the relevance of healthcare simulation to prepare future doctors to deliver bad news. A such, we designed a role-play workshop to train first-year residents enrolled in Lille University School of Medicine to break bad news. The objective of this work is to report on our experience of this training and to assess its educational value through its capacity to satisfy residents' expectations, to induce a feeling of ease towards bad news disclosure, and to change trainees' preconceptions regarding these situations. METHODS: The training consisted of a 45-minute heuristic reflective activity, aimed at identifying residents' preconceptions regarding bad news disclosure, followed by 4 30-min role-plays in which they played the parts of the physician, the patient and/or their relatives. Trainees were asked to answer 2 questionnaires (pre- and post-training), exploring previous experiences, preconceived ideas regarding bad news disclosure and workshop satisfaction. RESULTS: Almost all residents felt very satisfied with the workshop, which they regarded as formative (91%) and not too stressful (89%). The majority felt "more capable" (53% vs. 83%) and "more comfortable" (27% vs. 62%) to deliver bad news, especially regarding "finding the right words" (12% vs. 22%). Trainees tended to overestimate their skills before the workshop and lowered their assessment of their performance after attending the training, especially when they played the role of a patient in the simulation. CONCLUSION: Healthcare role-play seems an interesting technique for training to breaking bad news. Placing residents in the role of patients or relatives is an active approach that encourages reflexivity.

The impact of endotracheal intubation on oxygen delivery, trachea pressure and wall deformation.

This paper concerns improving endotracheal tube (ETT) insertion through advanced computational science modelling. The study aims to better understand endotracheal intubation (ETI) and reduce medical errors in intensive and critical care units since ETT insertion is unique for each patient, depending on age, gender, size, physiology, and underlying health conditions. We have employed computational fluid dynamics and biomechanics modelling to investigate the effect of ETT for three ventilation modes on (a) local oxygen delivery to the lungs, (b) air pressure and wall shear stress at the tracheal walls, and (c) oscillatory elastic deformation of the tracheal tissues and muscle. For the first time, we reveal how the ventilation mode and ETT insertion in the trachea may induce major complications, especially in long periods of ETT. We show that rotating the ETT or displacing it by 2 mm only can induce a significant rise in the tracheal pressure up to 177 cmH2O. This study, for the first time, shows the vital role of computers in biology and medicine to provide enhanced decision-making-support to clinicians and medical doctors dealing with ETI.

Use of a mobile application for self-management of pancreatic enzyme replacement therapy is associated with improved gastro-intestinal related quality of life in children with Cystic Fibrosis.

BACKGROUND: Most patients with cystic fibrosis (CF) suffer from pancreatic insufficiency (PI), leading to fat malabsorption, malnutrition, abdominal discomfort and impaired growth. Pancreatic enzyme replacement therapy (PERT) is effective, but evidence based guidelines for dose adjustment are lacking. A mobile app for self-management of PERT was developed in the context of the HORIZON 2020 project MyCyFAPP. It contains an algorithm to calculate individual PERT-doses for optimal fat digestion, based on in vitro and in vivo studies carried out in the same project. In addition, the app includes a symptoms diary, educational material, and it is linked to a web tool allowing health care professionals to evaluate patient's data and provide feedback. METHODS: A 6-month open label prospective multicenter interventional clinical trial was performed to assess effects of using the app on gastro-intestinal related quality of life (GI QOL), measured by the CF-PedsQL-GI (shortened, CF specific version of the Pediatric Quality of Life Inventory, Gastrointestinal Symptoms Module). RESULTS: One hundred and seventy-one patients with CF and PI between 2 and 18 years were recruited at 6 European CF centers. Self-reported CF-PedsQL-GI improved significantly from month 0 (M0) (84.3, 76.4-90.3) to month 6 (M6) (89.4, 80.35-93.5) (p< 0.0001). Similar improvements were reported by parents. Lower baseline CF-PedsQL-GI was associated with a greater improvement at M6 (p < 0.001). CONCLUSIONS: The results suggest that the MyCyFAPP may improve GI QOL for children with CF. This tool may help patients to improve self-management of PERT, especially those with considerable GI symptoms.

Paraquat poisoning in Western French Guyana: a public health problem persisting ten years after its withdrawal from the French market.

OBJECTIVE: Paraquat poisoning has almost disappeared from metropolitan France following its ban from the European market ten years ago. However, due to neighboring countries still authorizing paraquat use, French Guyana seems in a different situation. Here we aimed to report a series of paraquat-poisoned patients admitted to the emergency department of the Western French Guyana Hospital in Saint-Laurent du Maroni, to raise awareness of national health authorities on this persistent major issue. PATIENTS AND METHODS: We conducted a retrospective observational study describing the clinical features, the prognostic factors and the final outcome of paraquat-poisoned patients admitted to the emergency department between January 2008 and August 2014. RESULTS: Twenty-six paraquat-poisoned patients were included in the study. The median estimated paraquat dose intentionally ingested was 105 mg/kg (interquartile range, IQR: 359). Eighteen patients were treated with the cyclophosphamide/dexamethasone combination and seventeen with N-acetylcysteine in addition to the usual supportive care. Six patients survived and twenty died within a median 36h delay after admission (IQR: 130). Death was associated with cardiovascular (65%) and respiratory (35%) failure. Based on a bivariate analysis, predictive factors of death included (p≤0.05): advanced age, higher ingested paraquat dose, altered renal function, hypokalemia, acidosis, and dark blue dithionite test, observed on hospital admission. CONCLUSIONS: Paraquat poisoning still persists in French Guyana despite its withdrawal from the market. It is possible to determine the probability of death on patient admission based on routine clinical and biological parameters. There is an urgent need to request neighboring countries to ban paraquat with the aim of eradicating this dramatically life-threatening poisoning.

Are the results of intravenous thrombolysis trials reproduced in clinical practice? Comparison of observed and expected outcomes with the stroke-thrombolytic predictive instrument (STPI).

AIM: In patients with cerebral ischemia, intravenous (i.v.) recombinant tissue plasminogen activator (rt-PA) increases survival without handicap or dependency despite an increased risk of bleeding. This study evaluated whether the results of randomized controlled trials are reproduced in clinical practice. METHOD: Data from a registry of consecutive patients treated by rt-PA at Lille University Hospital were retrospectively analyzed for outcomes, using modified Rankin Scale (mRS) scores, at 3 months. The observed outcomes were then compared with the probability of good (mRS 0-1) and of catastrophic (mRS 5-6) outcomes, as predicted by the stroke-thrombolytic predictive instrument (STPI). RESULTS: Of the 1000 consecutive patients (469 male, median age 74 years, median baseline National Institutes of Health Stroke Scale 11, median onset-to-needle time 143min), 438 (43.8%) had a good outcome, 565 (56.5%) had an mRS score 0-2 or similar to their pre-stroke mRS, 155 (15.5%) died within 3 months and 74 (7.4%) developed symptomatic intracerebral hemorrhage according to ECASS-II (Second European-Australasian Acute Stroke Study) criteria. Of the 613 patients (61.3%) eligible for evaluation by the s-TPI, the observed rate of good outcomes was 41.3% (95% CI: 37.5-45.3%), while expected rates with and without rt-PA were 48.8% (95% CI: 44.8-52.7%) and 32.5% (95% CI: 28.8-36.2%), respectively; the observed rate of catastrophic outcomes was 17.0% (95% CI: 14.0-19.9%), while the expected rate was 19.2% (95% CI: 16.1-22.4%) with or without rt-PA. CONCLUSION: In clinical practice, the rate of good outcomes is slightly lower than expected, according to the s-TPI, except for the most severe cases, whereas the rate of catastrophic outcomes is roughly similar. However, the rate of good outcomes is higher than predicted without treatment. This finding suggests that rt-PA is effective for improving outcomes in clinical practice.

[Patient treated with sub-mental intubation for maxillofacial trauma]. / Intubation sub-mentale chez un patient victime d'un traumatisme maxillo-facial.

Maxillo-facial traumas are frequent and most often occur in young patients. Naso-tracheal or orotracheal intubation may be contraindicated in case of combined occlusal fracture and nasal or ethmoido-nasal fracture. This study was carried out a clinical case of a patient treated at the Lille University Hospital for a maxillofacial trauma associating fracture of nose and maxilla. The purpose was to assess the reliability of submental intubation as an alternative to tracheotomy. Submental intubation is a reliable single and safe technique allowing an one-stage surgical treatment in case of complex association of fractures without using tracheotomy. Its use should be implemented on a larger scale.

Effects of small airway dysfunction on the clinical expression of asthma: a focus on asthma symptoms and bronchial hyper-responsiveness.

BACKGROUND: The small airways are an important site of inflammation in asthma. However, the relation between small airway dysfunction and clinical expression of asthma has hardly been studied. AIM: To investigate the association of small and large airway dysfunction with asthma symptoms and bronchial hyper-responsiveness (BHR). METHODS: Fifty-eight patients with asthma were characterized with spirometry, body plethysmography, impulse oscillometry, alveolar and bronchial exhaled nitric oxide, and a methacholine provocation. Symptoms of nocturnal asthma, exercise-related symptoms, BHR symptoms, and respiratory symptoms were assessed with the Asthma Control Questionnaire and Bronchial Hyper-responsiveness Questionnaire. Perception of dyspnea was rated with the Borg score during the provocation test. RESULTS: Small and large airway dysfunction did not associate with higher scores for nocturnal, exercise-related, or BHR symptoms. Only higher scores on wheezing were significantly associated with higher values of difference between R5 and R20 (R5-R20) (r = 0.367, P < 0.01) and AX (r = 0.354, P < 0.01). Lower FEF25-75% (P = 0.024) and higher R5-R20 (P = 0.003) values were independently associated with more severe BHR to methacholine, but not FEV1 or R20 values. The increase in dyspnea during the methacholine provocation was strongly and independently correlated with the decrease in FEV1 and reactance of the respiratory system at 5 Hertz. CONCLUSION: Small and large airway dysfunction poorly associate with asthma symptoms in our patients. However, deteriorations in small airway dysfunction are strongly related to an increase in dyspnea during bronchial provocation with methacholine. Small airway dysfunction contributes also independently to the clinical expression of asthma, as reflected by the severity of BHR.

Rate of intravenous thrombolysis for acute ischaemic stroke in the North-of-France region and evolution over time.

The proportion of patients with ischaemic stroke treated by intravenous (i.v.) recombinant tissue plasminogen activator (rt-PA) is an indicator of quality of stroke care. The objective of the study is to evaluate the rate of i.v. thrombolysis in the North-of-France region and its evolution over time. We determined the proportion of inhabitants treated by i.v. rt-PA in 2009-2010 (period A; 8 stroke units, no telemedicine) and 2012 (period B; population campaigns, 12 stroke units with telemedicine in 5). We used hospital registries from the 12 stroke units, and population-based data were collected in a subpopulation of 226,827 inhabitants (5.6% of the whole population). 1,563 inhabitants received i.v. rt-PA for stroke (period A: 835 in 24 months; period B: 728 in 12 months). Hospital and population data were similar. Annual rates of thrombolysis increased from 103 per million inhabitants [95% confidence interval (CI) 85-125] to 181 (95% CI 157-209; relative increase 76%, 95% CI 67-83%). This rate increased in 12 districts (significantly in 6), but the increase was greater in districts where new stroke units, telemedicine, or both were implemented. In conclusion, although the proportion of patients treated was already high in period A, there was still place for improvement. Implementation of new stroke units, extension of the telemedicine network and new population campaigns are necessary to improve the rate of thrombolysis in several areas, to ensure an equal access to treatment over the whole territory. The next step is now to determine whether this high rate of i.v. rt-PA delivery at the population level translates into clinical results.

Unique blood culture for diagnosis of bloodstream infections in emergency departments: a prospective multicentre study.

Detection of microorganisms by blood cultures (BCs) is essential in managing patients with bacteraemia. Rather than the number of punctures, the volume of blood drawn is considered paramount in efficient and reliable detection of microorganisms. We performed a 1-year prospective multicentre study in adult emergency departments of three French university hospitals comparing two methods for BCs: a unique blood culture (UBC) collecting a large volume of blood (40 mL) and the standard method of multiple blood cultures (MBC). The performances of both methods for bacterial contamination and efficient microbial detection were compared, each patient serving as his own control. Amongst the 2314 patients included, three hundred were positive for pathogens (n=245) or contaminants (n=55). Out of the 245 patients, 11 were positive for pathogens by UBC but negative by MBC and seven negative by UBC but positive by MBC (p 0.480). In the subgroup of 137 patients with only two BCs, UBC was superior to MBC (p 0.044). Seven and 17 patients had contaminated BCs by UBC and MBC only, respectively (p 0.062). Considering the sums of pathogens missed and contaminants, UBC significantly outperformed MBC (p 0.045). Considering the complete picture of cost savings, efficient detection of microorganisms and decrease in contaminations, UBC offers an interesting alternative to MBC.

Less small airway dysfunction in asymptomatic bronchial hyperresponsiveness than in asthma.

BACKGROUND: Bronchial hyperresponsiveness (BHR) can be present in subjects without any respiratory symptoms. Little is known about the role of the small airways in asymptomatic subjects with BHR. METHODS: We investigated small airway function assessed by spirometry and impulse oscillometry, as well as Borg dyspnea scores at baseline and during a methacholine provocation test in 15 subjects with asymptomatic BHR, 15 asthma patients, and 15 healthy controls. RESULTS: At baseline, small airway function (R5 -R20 and X5 ) was comparable between subjects with asymptomatic BHR and healthy controls, whereas asthma patients showed small airway dysfunction as reflected by higher R5 -R20 and lower X5 values. During methacholine provocation, small airway dysfunction was more severe in asthma patients than in subjects with asymptomatic BHR. Interestingly, a higher increase in small airway dysfunction during methacholine provocation was associated with a higher increase in Borg dyspnea scores in subjects with asymptomatic BHR, but not in asthma patients. CONCLUSION: Subjects with asymptomatic BHR may experience fewer symptoms in daily life because they have less small airway dysfunction.

[Fever and jaundice... and if it was a leptospirosis. About a case of L. interrogans icterohaemorrhagiae in Northern France]. / Ictère fébrile et si c'était une leptospirose. À propos d'un cas de L. interrogans Icterohaemorrhagiae dans le Nord de la France.

Leptospirosis is an anthropozoonose, an animal disease transmissible to humans, caused by a spirochete of the genus Leptospira that lives mainly among rodents but also in wetlands. It occurs worldwide, particularly in Asia, Latin America and Africa. In Europe, the incidence is small (except in France and Great Britain, where its frequency has increased in recent years) but the frequency may be underestimated. Some areas overseas are particularly affected. In France, the potential epidemic of leptospirosis is subject to climatic variations, justifying a constant monitoring of the disease provided by the National Reference Centre (CNR) of leptospires. Transmission to humans primarily occurs through contact with environments contaminated by the urine of infected animals. The disease can affect the liver and kidneys (hepatonephritis) as cytolysis, cholestasis and renal failure associated with fever. A coagulopathy usually accompanies the clinical table. Its diagnosis is difficult because of the clinical polymorphism. Early diagnosis of leptospirosis allows effective medical care, improving patient outcomes. This is currently based on gene amplification (PCR) or serology positive by the microscopic agglutination test (MAT), which is the reference method. Its evolution is usually favorable with appropriate antibiotic treatment (aminopenicillin). However 5-10% of symptomatic patients have a severe multisystem defaillance. Nearly a century after the discovery of the causative agent, this zoonosis remains a public health problem, zoonosis priority in terms of virulence, its reporting is mandatory in our country. We report the case of a severe form of hepatonephritis due to water contaminated with Leptospira observed in Northern France.

[Sodium dichloroisocyanurate-induced acute lung injury in a child]. / Œdème pulmonaire lésionnel par intoxication au dichloro-isocyanurate de sodium.

Intoxication, by cyanurate and its chlorated derivatives in children, is increasingly reported in the literature due to accidental ingestion compared to accidental inhalation. We report a case in a 5-year-old child who presented with acute lung injury due to accidental inhalation of gas formed after a reaction of sodium dichloroisocyanurate tablets with water. Prevention remains the best way to reduce the risk of children being intoxicated by inhalation of the gas formed after contact of tablets with water.

Treatment of the bronchial tree from beginning to end: targeting small airway inflammation in asthma.

Asthma is a chronic respiratory disease, characterized by airway obstruction and inflammation. Increasing evidence shows that the small airways contribute significantly to the clinical expression and severity of asthma. Traditionally, high levels of disease activity are thought to be necessary before symptoms occur in the small airways because of their large reserve capacity. However, this concept is being challenged and increasing evidence shows small airway disease to be associated with symptoms, disease severity, and bronchial hyper-responsiveness. Particle size and distribution are of key importance when developing inhaled treatments for small airway disease. The availability of small-particle aerosols such as HFA-ciclesonide and HFA-beclomethasone dipropionate (HFA-BDP) enables a higher drug deposition into the peripheral lung and potentially provides additional clinical benefits compared with large-particle treatment. However, improved methods are needed to monitor and assess small airway disease and its response to treatment because conventional spirometry mainly reflects large airway function. This remains a challenging area requiring further research. The aim of the current manuscript is to review the clinical relevance of small airway disease and the implications for the treatment of asthma.

[National survey of transfusion practices in the neonatal period for the development of recommendations based on the "Haute Autorité de Santé methodology"]. / Enquête nationale sur les pratiques transfusionnelles pendant la période néonatale en vue de l'élaboration de recommandations selon la méthodologie de la Haute Autorité de santé.

Although transfusion practices have changed these last years, the neonatal period remains one period when the transfusion of blood components (in particular in red blood cells concentrates) is frequent, particularly for low birth weight premature babies. It is thus important to know well the pathophysiological characteristics specific to this age of life in order to reduce the risks of transfusion and to allow an optimal effectiveness of this treatment. Various studies on neonatal transfusion show that transfusion practices during the neonatal period are very heterogeneous from a team to another, and even within the same team. Therefore, we wanted to know the practices in France, by addressing a questionnaire to neonatology centres, in collaboration with the French Society Vigilance and Transfusion Therapy and the French Society of Neonatology (SFN). The results obtained confirm the heterogeneity of practices. To follow up on this study, we constituted a working group, in partnership with the SFN, the SFVTT and the EFS, with an aim of proposing good practice recommendations according to the methodology of the French "High Authority for Health", in order to homogenize at the national level transfusion practices of the new-born baby.
