Allogenic bone marrow-derived mesenchymal stromal cell-based therapy for patients with chronic low back pain: a prospective, multicentre, randomised placebo controlled trial (RESPINE study).

OBJECTIVES: To assess the efficacy of a single intradiscal injection of allogeneic bone marrow mesenchymal stromal cells (BM-MSCs) versus a sham placebo in patients with chronic low back pain (LBP). METHODS: Participants were randomised in a prospective, double-blind, controlled study to receive either sham injection or intradiscal injection of 20 million allogeneic BM-MSC, between April 2018 and December 2022. The first co-primary endpoint was the rate of responders defined by improvement of the Visual Analogue Scale (VAS) for pain of at least 20% and 20 mm, or improvement of the Oswestry Disability Index (ODI) of 20% between baseline and month 12. The secondary structural co-primary endpoint was assessed by the disc fluid content measured by quantitative MRI T2, between baseline and month 12. Secondary endpoints included pain VAS, ODI, the Short Form (SF)-36 and the minimal clinically important difference in all timepoints (1, 3, 6, 12 and 24 months). We determined the immune response associated with allogeneic cell injection between baseline and 6 months. Serious adverse events (SAEs) were recorded. RESULTS: 114 patients were randomised (n=58, BM-MSC group; n=56, sham placebo group). At 12 months, the primary outcome was not reached (74% in the BM-MSC group vs 69% in the placebo group; p=0.77). The groups did not differ in all secondary outcomes. No SAE related to the intervention occurred. CONCLUSIONS: While our study did not conclusively demonstrate the efficacy of allogeneic BM-MSCs for LBP, the procedure was safe. Long-term outcomes of MSC therapy for LBP are still being studied.

Can pain be self-managed? Pain change in vulnerable participants to a health education programme.

Chronic pain exerts a significant impact on the quality of life, giving rise to both physical and psycho-social vulnerabilities. It not only leads to direct costs associated with treatments, but also results in indirect costs due to the reduced productivity of affected individuals. Chronic conditions can be improved by reducing modifiable risk factors. Various educational programs, including the Chronic Disease Self-Management Programme (CDSMP), have demonstrated the advantages of enhancing patient empowerment and health literacy. Nevertheless, their efficacy in addressing pain symptoms has received limited attention, especially concerning vulnerable populations. This research aims to assess the effectiveness of the CDSMP in alleviating pain among socio-economically vulnerable participants with chronic conditions. By accounting for a wide range of variables, and using data from the EFFICHRONIC project (EU health programme), we investigated the changes in pain levels after the intervention, among 1070 participants from five European countries. Our analyses revealed a significant reduction in pain following the intervention. This finding supports the notion that training programs can effectively ameliorate pain and alleviate its impact on the quality of life, particularly in vulnerable populations. Younger participants, as well as those with higher education levels and individuals experiencing higher levels of pain at baseline, were more likely to experience a reduction in their pain levels. These findings underscore the importance of recognising the social determinants of health. The study was registered at ClinicalTrials.gov (ISRCTN70517103).

Evaluation of breast skin and tissue stiffness using a non-invasive aspiration device and impact of clinical predictors.

A personalized 3D breast model could present a real benefit for preoperative discussion with patients, surgical planning, and guidance. Breast tissue biomechanical properties have been poorly studied in vivo, although they are important for breast deformation simulation. The main objective of our study was to determine breast skin thickness and breast skin and adipose/fibroglandular tissue stiffness. The secondary objective was to assess clinical predictors of elasticity and thickness: age, smoking status, body mass index, contraception, pregnancies, breastfeeding, menopausal status, history of radiotherapy or breast surgery. Participants were included at the Montpellier University Breast Surgery Department from March to May 2022. Breast skin thickness was measured by ultrasonography, breast skin and adipose/fibroglandular tissue stiffnesses were determined with a VLASTIC non-invasive aspiration device at three different sites (breast segments I-III). Multivariable linear models were used to assess clinical predictors of elasticity and thickness. In this cohort of 196 women, the mean breast skin and adipose/fibroglandular tissue stiffness values were 39 and 3 kPa, respectively. The mean breast skin thickness was 1.83 mm. Only menopausal status was significantly correlated with breast skin thickness and adipose/fibroglandular tissue stiffness. The next step will be to implement these stiffness and thickness values in a biomechanical breast model and to evaluate its capacity to predict breast tissue deformations.

Immune-mediated diseases involving central and peripheral nervous systems.

BACKGROUND AND PURPOSE: In addition to combined central and peripheral demyelination, other immune diseases could involve both the central nervous system (CNS) and peripheral nervous system (PNS). METHODS: To identify immune-mediated diseases responsible for symptomatic combined central/peripheral nervous system involvement (ICCPs), we conducted a multicentric retrospective study and assessed clinical, electrophysiological, and radiological features of patients fulfilling our ICCP criteria. RESULTS: Thirty patients (20 males) were included and followed during a median of 79.5 months (interquartile range [IQR] = 43-145). The median age at onset was 51.5 years (IQR = 39-58). Patients were assigned to one of four groups: (i) monophasic disease with concomitant CNS/PNS involvement including anti-GQ1b syndrome (acute polyradiculoneuropathy + rhombencephalitis, n = 2), checkpoint inhibitor-related toxicities (acute polyradiculoneuropathy + encephalitis, n = 3), and anti-glial fibrillary acidic protein astrocytopathy (subacute polyradiculoneuropathy and meningoencephalomyelitis with linear gadolinium enhancements, n = 2); (ii) chronic course with concomitant CNS/PNS involvement including paraneoplastic syndromes (ganglionopathy/peripheral hyperexcitability + limbic encephalitis, n = 4); (iii) chronic course with sequential CNS/PNS involvement including POEMS (polyneuropathy, organomegaly, endocrinopathy, monoclonal protein, skin changes) syndrome (polyradiculoneuropathy + strokes, n = 2), histiocytosis (polyradiculoneuropathy + lepto-/pachymeningitis, n = 1), and systemic vasculitis (multineuropathy + CNS vasculitis/pachymeningitis, n = 2); and (iv) chronic course with concomitant or sequential CNS/PNS involvement including combined central and peripheral demyelination (polyradiculoneuropathy + CNS demyelinating lesions, n = 10) and connective tissue diseases (ganglionopathy/radiculopathy/multineuropathy + limbic encephalitis/transverse myelitis/stroke, n = 4). CONCLUSIONS: We diagnosed nine ICCPs. The timing of central and peripheral manifestations and the disease course help determine the underlying immune disease. When antibody against neuroglial antigen is identified, CNS and PNS involvement is systematically concomitant, suggesting a common CNS/PNS antigen and a simultaneous disruption of blood-nerve and blood-brain barriers.

Effects of social deprivation and healthcare access on major amputation following a diabetic foot ulcer in a French administrative area: Analysis using the French claim data.

AIM: The link between social deprivation and the development of diabetic foot ulcer (DFU) is still widely debated. The study objective was to evaluate the relationship between lower limb amputation, social deprivation level, and inequalities in access to care service among people with DFU. This regional pilot study was conducted at the living area level and based on the French National Health Data System (SNDS). METHODS: We conducted a retrospective cohort study using hospital and primary care claim data in the Languedoc-Roussillon region. DFUs were determined using an original algorithm of care consumption or hospital diagnosis. The primary end point was amputation at 1 year. Secondary end points were mortality at 1 year and impact of potential access to care on amputation. RESULTS: We included 15,507 people from 2015 to 2017. Amputation and mortality rates were 17.5 and 117 per 1000 person-years. The least precarious living areas showed better prognoses (relative risk = 0.46; 95% CI 0.27-0.66). Territorial accessibility to a private-practice nurse, unlike physician accessibility, was associated with better results on major outcomes (p = 0.004). CONCLUSION: This is the first study using SNDS to study the care pathway of DFU management within and outside the hospital. High social deprivation in a living areas seems to be associated with more major amputations after a DFU.

Type of headache at onset and risk for complications in reversible cerebral vasoconstriction syndrome.

BACKGROUND: In a recent Italian study, 30% of patients with reversible cerebral vasoconstriction syndrome (RCVS) presented without thunderclap headache (TCH), and tended to present more severe forms of RCVS than patients with TCH. We aimed to analyze the risk for complications of RCVS in patients with and without TCH at onset. METHODS: In a pooled cohort of 345 French patients with RCVS, we compared patients with and without TCH at onset regarding rates of neurological complications, and the functional outcome at 3 months. RESULTS: As compared to the 281 patients with TCH at onset, the 64 patients without TCH had a higher risk for any neurological complication (61% vs. 24%, OR 4.9, 95% CI 2.8-8.7, p < 0.001). The association was strongest for cervical artery dissections (28% vs. 5%, OR 8.1, 95% CI 3.7-17.6, p < 0.001), followed by posterior reversible encephalopathy syndrome (17% vs. 3%, OR 7.1, 95% CI 2.7-18.4, p < 0.001), seizures (9% vs. 2.5%, OR 4.1, 95% CI 1.3-12.5, p = 0.019), and subarachnoid hemorrhage (41% vs. 16%, OR 3.5, 95% CI 1.9-6.3, p < 0.001). In multivariable analysis, the risk for any neurological complication remained significantly elevated in the absence of TCH (OR 3.5, 95% CI 1.8-6.8, p < 0.001). The functional outcome was equal in both groups, with a modified Rankin scale score of 0-1 in ≥90% of patients. CONCLUSIONS: Absence of TCH at onset might predict a higher risk of complications in RCVS. Our results warrant further multicentric studies to prove this finding.

Nasopharyngeal Tube and Functional Treatment in Pierre Robin Sequence: A Tertiary Clinical Experience From 150 Cases.

OBJECTIVES: To describe the initial care practices for children with Pierre Robin sequence (PRS) and analyze the factors predicting the severity of the obstruction breathing disorders. DESIGN: A retrospective single-center study of 150 children with PRS. SETTING: Single tertiary care center, Regional Competence Center for the diagnosis and treatment of PRS. PATIENTS: A total of 150 children with PRS consecutively followed between 1986 and 2017. Group 1 comprises children without specific respiratory management; group 2, children requiring prone positioning to alleviate their respiratory distress symptoms; and group 3, children requiring nasopharyngeal airway tube (NT) or nonconservative surgical treatment. MAIN OUTCOME MEASURES: Evolution and results of the initial treatment of PRS. RESULTS: Forty-two percent (n = 63) were attributed to group 1, 39% (n = 50) to group 2, and 19% (n = 29) to group 3. Preterm birth, birth weight, or associated congenital malformations were not significantly different between the groups. However, the age of exclusive oral feeding was significantly different: 1 day (quartiles: 0-3) for group 1; 11 days (quartiles: 1-28) for group 2; 39 days (quartiles: 19-111) for group 3 (P < .0001). Considering the NT, its use relieves the upper airway obstruction, assessed by a respiratory polygraphy, in 14 children. CONCLUSIONS: Nasopharyngeal airway tube has become our major first-line treatment, avoiding more complex procedures in most of the cases. The achievement of exclusive oral feeding seems to be a good predictor of the severity of respiratory symptoms in PRS.

Long-Term Outcomes After Reversible Cerebral Vasoconstriction Syndrome.

Background and Purpose- We aimed to further investigate the long-term outcomes after reversible cerebral vasoconstriction syndrome (RCVS). Methods- A longitudinal follow-up study was conducted in 173 RCVS patients. Results- Of the 172 patients who completed a mean follow-up of 9.2±3.3 years, 10 had a recurrent RCVS that was benign in all. Independent predictors of relapse were having a history of migraine and having exercise as a trigger for thunderclap headache during initial RCVS. After new delivery, the rate of postpartum RCVS was 9%. Conclusions- Overall, long-term outcome after RCVS is excellent.

Immunopathological manifestations in Kabuki syndrome: a registry study of 177 individuals.

PURPOSE: Kabuki syndrome (KS) (OMIM 147920 and 300867) is a rare genetic disorder characterized by specific facial features, intellectual disability, and various malformations. Immunopathological manifestations seem prevalent and increase the morbimortality. To assess the frequency and severity of the manifestations, we measured the prevalence of immunopathological manifestations as well as genotype-phenotype correlations in KS individuals from a registry. METHODS: Data were for 177 KS individuals with KDM6A or KMT2D pathogenic variants. Questionnaires to clinicians were used to assess the presence of immunodeficiency and autoimmune diseases both on a clinical and biological basis. RESULTS: Overall, 44.1% (78/177) and 58.2% (46/79) of KS individuals exhibited infection susceptibility and hypogammaglobulinemia, respectively; 13.6% (24/177) had autoimmune disease (AID; 25.6% [11/43] in adults), 5.6% (10/177) with ≥2 AID manifestations. The most frequent AID manifestations were immune thrombocytopenic purpura (7.3% [13/177]) and autoimmune hemolytic anemia (4.0% [7/177]). Among nonhematological manifestations, vitiligo was frequent. Immune thrombocytopenic purpura was frequent with missense versus other types of variants (p = 0.027). CONCLUSION: The high prevalence of immunopathological manifestations in KS demonstrates the importance of systematic screening and efficient preventive management of these treatable and sometimes life-threatening conditions.

Growth charts in Kabuki syndrome 1.

Kabuki syndrome (KS, KS1: OMIM 147920 and KS2: OMIM 300867) is caused by pathogenic variations in KMT2D or KDM6A. KS is characterized by multiple congenital anomalies and neurodevelopmental disorders. Growth restriction is frequently reported. Here we aimed to create specific growth charts for individuals with KS1, identify parameters used for size prognosis and investigate the impact of growth hormone therapy on adult height. Growth parameters and parental size were obtained for 95 KS1 individuals (41 females). Growth charts for height, weight, body mass index (BMI) and occipitofrontal circumference were generated in standard deviation values for the first time in KS1. Statural growth of KS1 individuals was compared to parental target size. According to the charts, height, weight, BMI, and occipitofrontal circumference were lower for KS1 individuals than the normative French population. For males and females, the mean growth of KS1 individuals was -2 and -1.8 SD of their parental target size, respectively. Growth hormone therapy did not increase size beyond the predicted size. This study, from the largest cohort available, proposes growth charts for widespread use in the management of KS1, especially for size prognosis and screening of other diseases responsible for growth impairment beyond a calculated specific target size.

The effect of primary care on potentially avoidable hospitalizations in France: a cross-sectional study.

BACKGROUND: Potentially avoidable hospitalizations are an indirect measure of access to primary care. However, the role and quality of primary care might vary by geographical location. The main objective was to assess the impact of primary care on geographic variations of potentially avoidable hospitalizations in Occitanie, France. METHODS: We conducted a retrospective analysis of claims and socio-economic data for the French Occitanie region in 2014. In order to account for spatial heterogeneity, the region was split into two zones based on socio-economic traits: median pre-tax income and unemployment rate. Age- and sex-adjusted hospital discharge potentially avoidable hospitalization rates were calculated at the ZIP-code level. Demographic, socio-economic, and epidemiological determinants were retrieved, as well as data on supply of, access to and utilization of primary care. RESULTS: 72% of PAH are attributable to two chronic conditions: chronic obstructive pulmonary disease and heart failure. In Zone 1, the potentially avoidable hospitalization rate was positively associated with premature mortality and with the number of specialist encounters by patients. It was negatively associated with the density of nurses. In Zone 2, the potentially avoidable hospitalization rate was positively associated with premature mortality, with access to general practitioners, and with the number of nurse encounters by patients. It was negatively associated with the proportion of the population having at least one general practitioner encounter and with the density of nurses. CONCLUSIONS: This study suggests that the role of primary care in potentially avoidable hospitalizations might be geography dependent.

CLIPPERS and its mimics: evaluation of new criteria for the diagnosis of CLIPPERS.

OBJECTIVE: To evaluate the accuracy of the recently proposed diagnostic criteria for chronic lymphocytic inflammation with pontine perivascular enhancement responsive to steroids (CLIPPERS). METHODS: We enrolled 42 patients with hindbrain punctate and/or linear enhancements (<3 mm in diameter) and tested the CLIPPERS criteria. RESULTS: After a median follow-up of 50 months (IQR 25-82), 13 out of 42 patients were CLIPPERS-mimics: systemic and central nervous system lymphomas (n=7), primary central nervous system angiitis (n=4) and autoimmune gliopathies (n=2). The sensitivity and specificity of the CLIPPERS criteria were 93% and 69%, respectively. Nodular enhancement ( ≥ 3 mm in diameter), considered as a red flag in CLIPPERS criteria, was present in 4 out of 13 CLIPPERS-mimics but also in 2 out of 29 patients with CLIPPERS, explaining the lack of sensitivity. Four out of 13 CLIPPERS-mimics who initially met the CLIPPERS criteria displayed red flags at the second attack with a median time of 5.5 months (min 3, max 18), explaining the lack of specificity. One of these four patients had antimyelin oligodendrocyte glycoprotein antibodies, and the three remaining patients relapsed despite a daily dose of prednisone/prednisolone ≥ 30 mg and a biopsy targeting atypical enhancing lesions revealed a lymphoma. CONCLUSIONS: Our study highlights that (1) nodular enhancement should be considered more as an unusual finding than a red flag excluding the diagnosis of CLIPPERS; (2) red flags may occur up to 18 months after disease onset; (3) as opposed to CLIPPERS-mimics, no relapse occurs when the daily dose of prednisone/prednisolone is ≥ 30 mg; and (4) brain biopsy should target an atypical enhancing lesion when non-invasive investigations remain inconclusive.

A Clinico-Radiological Study of Cerebral Amyloid Angiopathy-Related Inflammation.

OBJECTIVE: To describe the clinico-radiological features and long-term prognosis in patients with cerebral amyloid angiopathy-related inflammation (CAA-ri). METHODS: Twenty-eight CAA-ri patients were recruited retrospectively from 6 neurological centers. We recorded the clinico-radiological and biological data, at baseline and during follow-up. Baseline characteristics associated with relapse risk and prognosis were assessed. RESULTS: Five patients had pathologically confirmed CAA-ri whereas 23 had probable (n = 21) or possible (n = 2) CAA-ri. The mean age was 72 years; main clinical symptoms included confusion (54%), hemiparesis (36%), and aphasia (29%). Cerebral MRI disclosed a brain parenchymal lesion (89%), which was usually multifocal (82%) and bilateral (89%). It was associated with gadolinium enhancement (84%), small ischemic lesions (39%), cortical superficial siderosis (CSS; 50%), and a high number of microbleeds (mean 240 ± 277). An isolated leptomeningeal involvement was observed in 3 patients with pathological confirmation. Despite a favorable initial evolution after treatment, we observed a 42% risk of relapse, mostly within the first year (83%). After a mean follow-up of 2 years, 29% died and 25% had a marked disability. Disseminated CSS was associated with death. CONCLUSION: Despite an apparently favorable initial evolution, CAA-ri is characterized by a poor prognosis. Diagnostic criteria should consider patients with isolated leptomeningeal involvement.

Identification of appropriate and potentially avoidable emergency department referrals in a tertiary cancer care center.

PURPOSE: Referrals to the Emergency Department can be distressing to patients with advanced cancer and may be a non-optimizing health care service. We aimed to describe the appropriateness and potential avoidability of Emergency Department referrals in a tertiary cancer care center where only physician referrals are allowed. METHODS: We prospectively reviewed the electronic medical charts of patients consecutively checked into the Emergency Department in August 2015. The appropriateness of referrals was assessed using a nationally validated classification (Classification Clinique des Malades aux Urgences) and local criteria. Potentially avoidable referrals were assessed using international classifications (Institute for Healthcare Improvement State Action on Avoidable Rehospitalizations diagnostic tool according to Kosecoff's criteria) and local criteria. RESULTS: We included 500 referrals related to 423 patients. The mean age was 59 years, and 74% of cancers were progressive. The referrals were appropriate in 61% of cases. They were deemed potentially avoidable "with a high likelihood" in 33.4% (CI95% [29.3-37.5]) of cases, potentially avoidable "with a moderate likelihood" in 14.4% (CI95% [11.3-17.5]) of cases, and "non-avoidable" in 52% (CI95% [47.6-56.4]) of cases. Opportunities to avoid referrals after an index stay involved this hospital stay or discharge process in 66 cases (28%), the follow-up period in 59 cases (25%), or both in 66 cases (28%). CONCLUSIONS: Potentially avoidable ED referrals are common in patients with cancer. These potentially avoidable ED referrals underline the importance of several domains of care coordination.

Endoscopic treatment of fistula after sleeve gastrectomy: results of a multicenter retrospective study.

BACKGROUND AND STUDY AIMS: Fistula is the main complication of laparoscopic sleeve gastrectomy (LSG), for which healing is difficult to achieve. The aims of the study were to evaluate the efficacy of interventional endoscopy for post-LSG fistula treatment, to evaluate various endoscopic techniques used and identify their complications, and to identify predictive factors of healing following endoscopic treatment. PATIENTS AND METHODS: This retrospective multicenter study included patients with post-LSG fistula. Therapeutic procedures were evaluated, taking into account complications and healing times. Endoscopic procedures were considered to have promoted healing if no other surgical procedure was performed. Predictive factors of healing were identified by univariate and multivariate analysis. RESULTS: A total of 110 patients were included, of whom 6 (5.5 %) healed spontaneously, 81 (73.6 %) healed following endoscopic treatment, and 19 (17.3 %) healed following surgery. Healing rates following endoscopic treatment were 84.4 % in the first 6 months of treatment (65/77), 52.4 % for treatment lasting 6 - 12 months (11/21), and 41.7 % after 12 months of treatment (5/12). A drainage procedure (surgical, endoscopic, or percutaneous) was performed in 92 patients (83.6 %). A total of 177 esogastric stents were placed in 88 patients (80.0 %). Surgical debridement, clip placement, glue sealing, and plug placement were also performed. Multivariate analysis identified four predictive factors of healing following endoscopic treatment: interval < 21 days between fistula diagnosis and first endoscopy (P = 0.003), small fistula (P = 0.01), interval between LSG and fistula ≤ 3 days (P = 0.01), no history of gastric banding (P = 0.04). CONCLUSION: Endoscopic treatment facilitated healing of post-LSG fistula in 74 % of patients. Early endoscopic treatment increased the likelihood of success, and was most effective during the first 6 months of management. After this point, surgical treatment should be considered.

Effectiveness of a pain neuroscience education programme on the physical activity of patients with chronic low back pain compared with a standard back school programme: protocol for a randomised controlled study (END-LC).

INTRODUCTION: Education is recognised as an effective and necessary approach in chronic low back pain. Nevertheless, data regarding the effectiveness of education in promoting physical activity in the medium term or long term are still limited, as are the factors that could lead to successful outcomes. Our study aims to assess the effectiveness of a pain neuroscience education programme compared with traditional back school on physical activity 3 months and 1 year after educational sessions coupled with a multidisciplinary rehabilitation programme. Additionally, we seek to evaluate the effects of these educational interventions on various factors, including pain intensity and psychobehavioural factors. Finally, our goal is to identify the determinants of success in educational sessions combined with the rehabilitation programme. METHODS AND ANALYSIS: The study will involve 82 adults with chronic low back pain. It will be a monocentric, open, controlled, randomised, superiority trial with two parallel arms: an experimental group, 'pain neuroscience education', and a control group, 'back school'. The primary outcome is the average number of steps taken at home over a week, measured by an actigraph. Secondary outcomes include behavioural assessments. Descriptive and inferential analysis will be conducted. Multivariate modelling will be performed using actimetric data and data from the primary and secondary outcomes. ETHICS AND DISSEMINATION: The Committee for Personal Protection of Ile de France VII (CPP) gave a favourable opinion on 22 June 2023 (National number: 2023-A00346-39). The study was previously registered with the National Agency for the Safety of Medicines and Health Products (IDRCB: 2023-A00346-39). Participants signed an informed consent during the inclusion visit. This protocol is the version submitted to the CPP entitled 'Protocol Version N°1 of 03/29/2023'. The results of the study will be presented nationally and internationally through conferences and publications. TRIAL REGISTRATION NUMBER: NCT05840302.

Training Family Medicine Residents in Dermoscopy Using an e-Learning Course: Pilot Interventional Study.

BACKGROUND: Skin cancers are the most common group of cancers diagnosed worldwide. Aging and sun exposure increase their risk. The decline in the number of dermatologists is pushing the issue of dermatological screening back onto family doctors. Dermoscopy is an easy-to-use tool that increases the sensitivity of melanoma diagnosis by 60% to 90%, but its use is limited due to lack of training. The characteristics of "ideal" dermoscopy training have yet to be established. We created a Moodle (Moodle HQ)-based e-learning course to train family medicine residents in dermoscopy. OBJECTIVE: This study aimed to evaluate the evolution of dermoscopy knowledge among family doctors immediately and 1 and 3 months after e-learning training. METHODS: We conducted a prospective interventional study between April and November 2020 to evaluate an educational program intended for family medicine residents at the University of Montpellier-Nîmes, France. They were asked to complete an e-learning course consisting of 2 modules, with an assessment quiz repeated at 1 (M1) and 3 months (M3). The course was based on a 2-step algorithm, a method of dermoscopic analysis of pigmented skin lesions that is internationally accepted. The objectives of modules 1 and 2 were to differentiate melanocytic lesions from nonmelanocytic lesions and to precisely identify skin lesions by looking for dermoscopic morphological criteria specific to each lesion. Each module consisted of 15 questions with immediate feedback after each question. RESULTS: In total, 134 residents were included, and 66.4% (n=89) and 47% (n=63) of trainees fully participated in the evaluation of module 1 and module 2, respectively. This study showed a significant score improvement 3 months after the training course in 92.1% (n=82) of participants for module 1 and 87.3% (n=55) of participants for module 2 (P<.001). The majority of the participants expressed satisfaction (n=48, 90.6%) with the training course, and 96.3% (n=51) planned to use a dermatoscope in their future practice. Regarding final scores, the only variable that was statistically significant was the resident's initial scores (P=.003) for module 1. No measured variable was found to be associated with retention (midtraining or final evaluation) for module 2. Residents who had completed at least 1 dermatology rotation during medical school had significantly higher initial scores in module 1 at M0 (P=.03). Residents who reported having completed at least 1 dermatology rotation during their family medicine training had a statistically significant higher score at M1 for module 1 and M3 for module 2 (P=.01 and P=.001). CONCLUSIONS: The integration of an e-learning training course in dermoscopy into the curriculum of FM residents results in a significant improvement in their diagnosis skills and meets their expectations. Developing a program combining an e-learning course and face-to-face training for residents is likely to result in more frequent and effective dermoscopy use by family doctors.

Endoscopic prophylactic nipple-sparing mastectomy: First French survey of 10 patients.

INTRODUCTION: Current recommendations preconize prophylactic mastectomy for women over 30 with increased risk of breast cancer. Several surgical techniques are available to perform bilateral mastectomy with or without breast reconstruction. Our primary objective was to evaluate the feasibility of the Endoscopic Nipple Sparing Mastectomy (E-NSM) technique, without robotic assistance, using a single axillary incision and with immediate reconstruction using a prepectoral prosthesis in prophylactic indications. The secondary objectives were to evaluate the risks of postoperative complications and the esthetic results. MATERIAL AND METHODS: This is a preliminary report of a prospective single-center interventional clinical study with a final enrolment target of 20 patients. The primary endpoint was the rate of complete surgical procedures per E-NSM. The secondary endpoints were the rate of conversions to conventional surgery, infections, hematomas, skin injury, pain and esthetic results (Breast-Q questionnaire, additional cosmetic procedures). RESULTS: From April 2019 to June 2022, 10 patients were included for 19 procedures (9 bilateral mastectomies, 1 unilateral). All surgical procedures were complete; no conversion to conventional surgery was required. The rate of complications per procedure requiring revision surgery was 16 % (1 skin necrosis, 1 postoperative hematoma and 1 surgical site infection). No prosthesis was removed. The seroma rate was 5 %. All patients would recommend this technique and were very satisfied or satisfied with the esthetic result. A second cosmetic procedure (lipofilling) was necessary in 50 % of patients. DISCUSSION: These preliminary data attest to the feasibility and safety of the E-NSM approach, and should be confirmed on a larger cohort and longer-term follow-up. GOV IDENTIFIER: NCT03838549.

An e-Learning Course to Train General Practitioners in Planetary Health: Pilot Intervention Study.

BACKGROUND: According to the World Health Organization, climate and ecological emergencies are already major threats to human health. Unabated climate change will cause 3.4 million deaths per year by the end of the century, and health-related deaths in the population aged ≥65 years will increase by 1540%. Planetary health (PH) is based on the understanding that human health and human civilization depend on flourishing natural systems and the wise stewardship of those natural systems. Health care systems collectively produce global emissions equivalent to those of the fifth largest country on earth, and they should take steps to reduce their environmental impact. Primary care in France accounts for 23% of greenhouse gas emissions in the health care sector. General practitioners (GPs) have an important role in PH. The course offers first-year GP residents of the Montpellier-Nîmes Faculty of Medicine a blended-learning course on environmental health. An e-learning module on PH, lasting 30 to 45 minutes, has been introduced in this course. OBJECTIVE: The objective of this study was to assess the impact of the e-learning module on participants' knowledge and behavior change. METHODS: This was a before-and-after study. The module consisted of 3 parts: introduction, degradation of ecosystems and health (based on the Intergovernmental Panel on Climate Change report and planetary limits), and ecoresponsibility (based on the Shift Project report on the impact of the health care system on the environment). The questionnaire used Likert scales to self-assess 10 points of knowledge and 5 points of PH-related behavior. RESULTS: A total of 95 participants completed the pre- and posttest questionnaires (response rate 55%). The mean scores for participants' pretest knowledge and behaviors were 3.88/5 (SD 0.362) and 3.45/5 (SD 0.705), respectively. There was no statistically significant variation in the results according to age or gender. The pretest mean score of participants who had already taken PH training was statistically better than those who had not taken the PH training before this course (mean 4.05, SD 0.16 vs mean 3.71, SD 0.374; P<.001). CONCLUSIONS: The PH module of the Primary Care Environment and Health course significantly improved self-assessment knowledge scores and positively modified PH behaviors among GP residents. Further work is needed to study whether these self-declared behaviors are translated into practice.

The Primary Care and Environmental Health e-Learning Course to Integrate Environmental Health in General Practice: Before-and-After Feasibility Study.

BACKGROUND: Environmental and behavioral factors are responsible for 12.6 million deaths annually and contribute to 25% of deaths and chronic diseases worldwide. Through the One Health initiative, the World Health Organization and other international health organizations plan to improve these indicators to create healthier environments by 2030. To meet this challenge, training primary care professionals should be the priority of national policies. General practitioners (GPs) are ready to become involved but need in-depth training to gain and apply environmental health (EH) knowledge to their practice. In response, we designed the Primary Care Environment and Health (PCEH) online course in partnership with the Occitanie Regional Health Agency in France. This course was used to train GP residents from the Montpelier-Nimes Faculty of Medicine in EH knowledge. The course was organized in 2 successive parts: (1) an asynchronous e-learning modular course focusing on EH knowledge and tools and (2) 1 day of face-to-face sessions. OBJECTIVE: This study assessed the impact of the e-learning component of the PCEH course on participants' satisfaction, knowledge, and behavior changes toward EH. METHODS: This was a pilot before-and-after study. Four modules were available in the 6-hour e-learning course: introduction to EH, population-based approach (mapping tools and resources), clinical cases, and communication tools. From August to September 2021, we recruited first-year GP residents from the University of Montpellier (N=130). Participants' satisfaction, knowledge improvements for 19 EH risks, procedure to report EH risks to health authorities online, and behavior change (to consider the possible effects of the environment on their own and their patients' health) were assessed using self-reported questionnaires on a Likert scale (1-5). Paired Student t tests and the McNemar χ2 test were used to compare quantitative and qualitative variables, respectively, before and after the course. RESULTS: A total of 74 GP residents completed the e-learning and answered the pre- and posttest questionnaires. The mean satisfaction score was 4.0 (SD 0.9) out of 5. Knowledge scores of EH risks increased significantly after the e-learning course, with a mean difference of 30% (P<.001) for all items. Behavioral scores improved significantly by 18% for the participant's health and by 26% for patients' health (P<.001). These improvements did not vary significantly according to participant characteristics (eg, sex, children, place of work). CONCLUSIONS: The e-learning course improved knowledge and behavior related to EH. Further studies are needed to assess the impact of the PCEH course on clinical practice and potential benefits for patients. This course was designed to serve as a knowledge base that could be reused each year with a view toward sustainability. This course will integrate new modules and will be adapted to the evolution of EH status indicators and target population needs.
