Real-world data of in-hospital administration of alglucosidase alfa in French patients with Pompe disease: results from the National Claims Database.

INTRODUCTION: Pompe disease is caused by a rare biallelic mutation in the GAA gene resulting in acid α-glucosidase deficiency and glycogen accumulation. AIM: We analyzed hospital admissions associated with the administration of Myozyme®, utilizing the French hospital discharge database, known in France as the Programme de Médicalisation des Systèmes d'Information (PMSI), which comprehensively captures all hospital activity within the country. METHODS: In this observational study, we examined hospitalization records from April 4, 2012, to December 31, 2019, within the PMSI database, focusing on admissions where Myozyme® was administered. We particularly investigated the incidence of critical care admissions and adverse events (AEs) related to Myozyme®. RESULTS: From 2012 to 2019, approximately 26,714 hospital stays involving Myozyme® administration were recorded for 239 patients. Most (96.6%) of these were outpatient stays, with only 3.2% in critical care. Furthermore, hospitalizations without critical care needs increased from 96% in 2012 to 99% in 2019. Of the patients receiving at least one infusion, 997 critical care admissions were recorded, with 781 (78.3%) occurring concurrent with or the day after the Myozyme® treatment without directly correlating to adverse effects of enzyme therapy. CONCLUSIONS: The analysis of the French hospital discharge database indicated that Myozyme® was associated with a low incidence of AEs and complications in a hospital context, supporting the consideration of its safe use in home-infusion settings.

Aquatic conditions & bacterial communities as drivers of the decomposition of submerged remains.

Aquatic decomposition, as a forensic discipline, has been largely under-investigated as a consequence of the highly complex and influential variability of the water environment. The limitation to the adaptability of scenario specific results justifies the necessity for experimental research to increase our understanding of the aquatic environment and the development of post-mortem submersion interval (PMSI) methods of estimation. This preliminary research aims to address this contextual gap by assessing the variation in the bacterial composition of aquatic biofilms as explained by water parameter measurements over time, associated with clothed and bare decomposing remains. As part of three field investigations, a total of 9 still-born piglets (n = 3, per trial) were used as human analogues and were submerged bare or clothed in either natural cotton or synthetic nylon. Changes in the bacterial community composition of the water surrounding the submerged remains were assessed at 4 discrete time points post submersion (7, 14, 21 and 28 days) by 16 S rRNA gene Next Generation Sequencing analysis and compared to coinciding water parameter measurements (i.e. conductivity, total dissolved solids (TDS), salinity, pH, and dissolved oxygen (DO)). Bacterial diversity was found to change over time and relative to clothing type, where significant variation was observed between synthetic nylon samples and bare/cotton samples. Seasonality was a major driver of bacterial diversity, where substantial variation was found between samples collected in early winter to those collected in mid - late winter. Water parameter measures of pH, salinity and DO were identified to best explain the global bacterial community composition and their corresponding dynamic trajectory patterns overtime. Further investigation into bacterial community dynamics in accordance with varying environmental conditions could potentially lead to the determination of influential extrinsic factors that may drive bacterial activity in aquatic decomposition. Together with the identification of potential bacterial markers that complement the different stages of decomposition, this may provide a future approach to PMSI estimations.

Penile prosthesis for erectile dysfunction in France: A six-year nationwide database analysis.

INTRODUCTION: Urological consultations for erectile dysfunction (ED) are increasing worldwide. Penile prosthesis (PP) implantations are performed when other treatments are unsuccessful. However, there is no data regarding PP implantations in France beyond the year 2016. OBJECTIVES: This study aimed to describe the changes in the number and type of PP implants used for the treatment of ED in France from 2016 to 2021 and the hospitalization rates following implantation using French national data from the Program for the Medicalization of Information Systems (PMSI). MATERIALS AND METHODS: We analyzed data on PP implantations in all France hospitals. PPs were coded into three types according to the Common Classification of Medical Procedures (CCAM). The number of patients admitted to hospital with complications twelve months after implantation was also recorded. RESULTS: During the study period, 3675 men received 3868 PPs in France. A gradual increase in the total number of implanted PPs was observed, with an overall increase of 33.8%. In 2020, there was a sharp decline in the number of implanted PPs, primarily owing to the COVID-19 pandemic. The most commonly used implant was PPs with an extracavernous compartment, comprising 85% of all PPs. Twelve months after implantation, only 1-2% of the patients were rehospitalized. CONCLUSION: PP implantation surgeries are highly reproducible and have a low incidence of complications, in terms of rehospitalization after one year of placement (1.8%). Moreover, there was an increase in the demand for penile prosthesis implantations in France between 2016 and 2021. LEVEL OF EVIDENCE: 4: Descriptive epidemiological study.

Bariatric surgery reduces the incidence of hidradenitis suppurativa in individuals with obesity: results of a nationwide administrative data study in France.

BACKGROUND: Hidradenitis suppurativa (HS) is a systemic inflammatory condition associated with obesity, metabolic syndrome, and environmental factors. Bariatric surgery (BS) is effective in reducing weight and resolving obesity-related medical problems. OBJECTIVES: The aim of this case-control study is to evaluate the effects of BS on the occurrence and recurrence of HS in individuals with obesity. SETTING: Nationwide administrative data study using the French national discharge database. METHODS: We compared 297,776 individuals with obesity and without a history of HS who underwent BS (BS group) with 2,735,930 individuals with obesity who did not receive BS (control group) to assess the incidence of de novo HS. From the same database, we compared hospitalization rates for HS recurrence between 310 individuals with obesity and HS who had BS (HS_BS group) and 3875 individuals with obesity who did not have BS (HS_control group). Propensity score matching using the nearest-neighbor method was implemented to create comparable patient groups. RESULTS: Individuals with obesity and without a history of HS who received BS exhibited a significantly reduced risk of developing de novo HS (RR = .736 [.639; .847]). Among patients with a history of HS, those who underwent BS had a nonsignificantly reduced risk of HS recurrence (RR = .676 [.369; 1.238]) compared with those who did not. CONCLUSION: BS reduces the risk of developing de novo HS and seems to have a protective effect on its recurrence in individuals with obesity, although the latter effect was not statistically significant.

Clinical care pathways of patients with biliary tract cancer: A French nationwide longitudinal cohort study.

BACKGROUND: Although the incidence of BTC is raising, national healthcare strategies to improve care lack. We aimed to explore patient clinical care pathways and strategies to improve biliary tract cancer (BTC) care. METHODS: We analysed the French National Healthcare database of all BTC inpatients between January 1, 2017 and December 31, 2021. Multinomial logistic regression adjusted odds ratios (aOR) were used to identify healthcare organisation factors that influenced access to curative care both overall and in a longitudinal sensibility analysis using optimal matching and hierarchical ascending classification to detect a subgroup of curative-care patients with a high survival over a two-year period. RESULTS: A total of 19,825 new BTC patients and three clinical care pathways (CCP) were identified: 'Palliative care' (PC-CCP), 'Non-curative Care' (NCC-CCP) and 'Curative Care' (CC-CCP) involving 7669 (38.7%), 7721 (38.9%) and 4435 (22.4%) patients respectively. Out of 1200 centers involved in BTC treatment, 84%, 11% and 5% were of low- (<15 patients/year), medium- (15-30 patients/year) and high-volume (>30 patients/year) respectively. Among patient, tumor and hospital factors, BTC management in academic (aOR: 2.32; 95%CI: 1.98-2.71), private (2.51; 2.22-2.83), semi-private (2.25; 1.91-2.65) and in high- (2.09; 1.81-2.42) or medium-volume (1.49; 1.33-1.68) centers increased probability to CC-CCP. These results were maintained in a longitudinal cluster of 2363 (53%) CC-CCP patients presenting a higher two-year survival compared with the rest [96.4% (95.1; 97.6) vs. 38.8% (36.3; 41.4), log-rank p < 0.001]. CONCLUSIONS: Among factors subject to healthcare policy improvement, the volume and type of centers managing BTC strongly influenced access to curative care.

Population characteristics, healthcare pathways and outcomes of patients with cirrhosis hospitalized with overt hepatic encephalopathy in France: A study of the French Hospital-Discharge Database.

Hepatic encephalopathy (HE) is a severe complication of cirrhosis, independently associated with a poor survival. The objectives of this study were to describe the prevalence of overt hepatic encephalopathy (OHE) requiring hospitalization, and the healthcare pathways and outcomes of patients hospitalized for OHE in France. Data from the French Hospital-Discharge Database (Programme de Medicalisation des Systemes d'information, PMSI) within the 5-year period from 2014 to 2018 were analysed. Since the disease lacks a PMSI code in the ICD-10, an identification algorithm was developed. The analysis identified 57,191 patients with OHE including 48,566 patients (85 %) who had been hospitalized twice or more during the study period. Each year, an average of over 20,000 patients were hospitalized in France for OHE as the primary or secondary reason for hospitalization. Among these patients, between 11,500 and 13,500 had been hospitalized at least twice in that year with an average of 3.4 hospitalisations per year. 25 % of admissions occurred following consultation at the emergency unit. Among hospitalisations, 15 % involved admission to the critical care resuscitation unit or intensive care. For all patients identified as suffering from OHE and hospitalized, the 5-year mortality was 46.5 % (26,621 patients). This pioneering study revealed that, in France, despite a probable underestimation of OHE episodes due to the lack of specific PMSI coding, the prevalence of OHE was very high, with frequent recurrences and readmissions, and high mortality.

Characteristics, management, and healthcare resources of patients with advanced non-small-cell lung cancer surviving 5 years after nivolumab treatment initiation: A national database analysis.

BACKGROUND: Data on long-term survivors with advanced non-small-cell lung cancer (NSCLC) treated with nivolumab are available from randomized trials. Characteristics, management, and healthcare resources of those patients need to be confirmed with real-world data. METHODS: The UNIVOC retrospective observational study included all patients with advanced NSCLC recorded in the French national hospital database starting nivolumab in 2015 and followed them until December 2020. The Kaplan-Meier method estimated the overall survival (OS). A machine learning approach identified patients with similar treatment sequences. RESULTS: Within the 3,050 patients who had nivolumab initiation,5-year OS rate was 14.6 % (95 %CI 13.3 %-16.2 %). In total, data covering at least 5 years of follow-up were retrieved for 231 surviving patients. Survivors were younger, often female and had fewer comorbidities than non-survivors. Three clusters of patients with different nivolumab treatment durations were identified: 1/ Continuous nivolumab treatment; 2/ Long period of nivolumab treatment followed by chemotherapy or no treatment; 3/ Short period of nivolumab treatment then chemotherapy or no treatment. At 5 years, 61.0 % of survivors were no longer receiving systemic therapy, 26.4 % were treated with nivolumab, 8.7 % chemotherapy, and 3.9 % other immunotherapies. Among 5-y survivor patients, the average number of hospitalisations per patient decreased from 23.4 to 12.8 between the 1st and the 5th year. In the 5th year, 46 % of patients had no more hospitalization for lung cancer. CONCLUSIONS: This large nationwide study confirms the long-term benefit of nivolumab treatment for advanced NSCLC patients in the real-world setting, with a 5-year survival rate similar to that reported in clinical trials.

Accessing specialty consultations and procedures in Centre-Val de Loire region / Accès aux actes et consultations de second recours en région Centre-Val de Loire

Introduction: In the Centre-Val de Loire region, the demography of specialty care is characterized by a strong deficit and many territorial inequalities that lead to significant difficulties in accessing care. The study has being conducted at the level of the Professional Territorial Health Communities (CPTS) which structuring the region, which is the ideal framework for implementing public health actions resulting from this study. Purpose of research: The aim of this study was to objectify these difficulties and their geography, based on the calculation of the comparative consumption index (CCI), in order to measure the differences between expected consumption and observed consumption, and to quantify the number of "missing" doctors to meet the needs of the population. Results: The study shows a deficit in care-seeking for specialty care, in particular an incompatibility between care needs and care offers in the living environment, as well as strong territorial inequalities, with marked differences between private consumption and hospital consumption. The region experiences a deficit of 25% of liberal medical specialists in order to meet the needs of its population. Conclusions: Accessibility to care is not only defined by the proximity of doctors, and their density; the proximity of areas of activity being a factor associated with better access to health care. This study also makes it possible to identify priority areas of action, specialty by specialty, to strengthen access to specialty care, and propose a fairer distribution of the care offer, in particular through interns' internships, and the coordinated and territorial organization of specialist doctors.

Introduction: En région Centre-Val de Loire, l'offre de soins de second recours se caractérise par une démographie déficitaire et par de fortes inégalités territoriales, entraînant d'importantes difficultés d'accès aux soins. L'étude a été menée à l'échelle des communautés professionnelles territoriales de santé (CPTS) maillant la région, cadre idéal pour concrétiser des actions de santé publique. But de l'étude: Le but de cette étude était d'objectiver ces difficultés et leur géographie, sur la base du calcul de l'indice comparatif de consommation (ICC), afin de mesurer les écarts entre la consommation attendue et la consommation observée, et de quantifier le nombre de médecins nécessaires pour répondre aux besoins de la population, et qui sont donc actuellement « manquants ¼. Résultats: On observe un sous-recours aux soins de spécialité, notamment une inadéquation entre les besoins et l'offre de soins sur les lieux de vie, ainsi que de fortes inégalités territoriales, avec des différences marquées entre le recours libéral et le recours aux actes et consultations externes en secteur hospitalier. La région connaîtrait un déficit de 25 % de médecins spécialistes libéraux pour répondre aux besoins de sa population. Conclusions: L'accessibilité aux soins ne se résume pas à la proximité des soignants ni à leur densité, la proximité de zones d'activité étant un facteur associé à un meilleur recours aux soins. Cette étude permet d'identifier des zones d'action prioritaire par spécialité, pour renforcer l'accès au second recours et construire une plus juste répartition de l'offre, notamment par le déploiement de stages d'internes et l'organisation coordonnée et territoriale des médecins spécialistes hors médecine générale.

Complications after partial nephrectomy: robotics overcomes open surgery and laparoscopy: the PMSI French national database.

PURPOSE: To evaluate three partial nephrectomies (PN) procedures: open (OPN), standard laparoscopy (LPN), and robot-assisted laparoscopy (RAPN), for the risk of initial complications and rehospitalization for two years after the surgery. MATERIALS AND METHODS: From the French national hospital database (PMSI-MCO), every hospitalization in French hospitals for renal tumor PN in 2016-2017 were extracted. Complications were documented from the initial hospitalization and any rehospitalization over two years. Chi-square and ANOVA tests compared the frequency of complications and length of initial hospitalization between the three surgical procedures. Relative risks (RR) and 95% confidence intervals were computed. RESULTS: The 9119 initial hospitalizations included 4035 OPN, 1709 LPN, and 1900 RAPN; 1475 were excluded as the laparoscopic procedure performed was not determined. The average length of hospitalization was 8.1, 6.2, and 4.5 days for OPN, LPN, and RAPN, respectively. Compared to OPN, there were fewer complications at the time of initial hospitalization for the mini-invasive procedures: 29% for OPN vs. 20% for LPN (0.70 [0.63;0.78]) and 12% for RAPN (RR=0.43, 95%CI [0.38;0.49]). For RAPN compared to LPN, there were fewer haemorrhages (RR=0.55 [0.43;0.72]), anemia (0.69 {0.48;0.98]), and sepsis (0.51 [0.36;0.71]); during follow up, there were fewer urinary tract infections (0.64 [0.45;0.91]) but more infectious lung diseases (1.69 [1.03;2.76]). Over the two-year postoperative period, RAPN was associated with fewer acute renal failures (RR=0.73 [0.55;0.98]), renal abscesses (0.41 [0.23;0.74]), parietal complications (0.69 [0.52;0.92]) and urinary tract infections (0.54 [0.40;0.73]) than for OPN. CONCLUSIONS: Conservative renal surgery is associated with postoperative morbidity related to the surgical procedure fashion. Mini-invasive procedures, especially robot-assisted surgery, had fewer complications and shorter hospital lengths of stay.

[Rythmology activity in France and consequences of new thresholds approvals]. / État de l'activité de rythmologie interventionnelle en France et conséquences des réformes des seuils sur les autorisations d'activité.

BACKGROUND: Interventional rhythmology activity (electrophysiology and pacing) has progressed in France during the last decade. The objective of this article is to assess the distribution of this activity depending on the type of centre (public, university or non-university, private). As the French government issued a new regulation regarding rhythmology activity in 2022, the impact of this regulation on activity distribution has been evaluated. METHODOLOGY: All French data activity can be evaluated after accessing to a national database called PMSI [Programme de Médicalisation des Systèmes d'Information]. Based on data collected in year 2021, the level of activity of the different centres, and the impact of the new criteria of the French regulation regarding rhythmology activity have been analysed. RESULTS: About 200,000 arrhythmias interventions have been done in France in 2021 in 382 centres. According to the new criteria of the French regulation, 66% responded to level A (diagnostic electrophysiology, single- and dual-chamber pacing), 68% for level B (A+ right atrial ablation, implantable automatic defibrillator, cardiac resynchronisation therapy) and 70% for level C (B + left atrial and ventricular ablation). 1/4 of the centres do not meet criteria for level A activity, and 1/5 of them for levels B and C CONCLUSIONS: This work showed that immediat and systematic application of new threshold could be threatening for 1/4 of A center and 1/5 of B or C center. The priority will be to reinforce existing centres before allowing new centres to perform arrhythmias management activity in France.

Assessment of post-mortem submersion interval using total aquatic decomposition scores of drowned human cadavers.

Investigating drowning-related deaths remains a significant problem for forensic personnel all over the world. The previously published decomposition scoring method like the total aquatic decomposition (TAD) score promises to estimate the correct post-mortem submersion interval (PMSI) in aquatic habitats through the assessment and calculation of the decomposition rate and accumulated degree days (ADD). The current study comprised of 53 drowned death cases belonging to various districts of Haryana from May 2016 to August 2017. The regression and Pearson's correlation indicated a significant correlation between the TAD scores and the actual ADD (calculated through water temperatures) (r2  = 0.917) and between the actual and the estimated ADDs (calculated through TAD scores used by Heaton et al. [21]) (r = 0.9585). The results indicated that the estimated ADD tends to over predict the PMSI compared to the actual ADD. It is further confirmed by paired t-test, which showed the mean of actual ADD (mean = 349) to be significantly lower than the mean of estimated ADD (mean = 663). Moreover, these methods will help forensic investigators and researchers formulate region-specific regression equations for PMSI estimation.

Innovative Approach for a Typology of Treatment Sequences in Early Stage HER2 Positive Breast Cancer Patients Treated With Trastuzumab in the French National Hospital Database.

Background: Our objective was to describe the hospital-based systemic treatment sequences in early stage HER2+ breast cancer patients treated with trastuzumab in France in 2016. Methods: This retrospective observational study was based on the national hospital discharge database (PMSI). Patients hospitalized for breast cancer in 2016 and administration of trastuzumab between 6 months prior and 1 year after surgery were included. The following treatments were identified: (1) trastuzumab ± chemotherapy; (2) chemotherapy alone; (3) q3w trastuzumab weekly chemotherapy. Hospital admissions for cardiac events before and after the surgery were investigated. An unsupervised machine learning technic called TAK (Time-sequence Analysis through K-clustering) was used to identify and visualize typical systemic treatment sequences. Results: Overall, 3531 patients were included: 2619 adjuvant cohort patients (74.2%) and 912 neoadjuvant cohort patients (25.8%). The mean age was 56.4 years (±12.3), 99.7% patients were female. Treatment initiation occurred within 6 weeks of the surgery in 58% and 92% of patients, and trastuzumab treatment lasted 12 months (±1 month) in 75% and 66% of patients in the adjuvant and neoadjuvant cohorts, respectively. Nevertheless, 12% and 22% of patients were treated with trastuzumab for <11 months in the adjuvant and neoadjuvant cohorts, respectively. There was not one standard sequence of treatments per cohort, but 4 and 3 typical treatment sequences in the adjuvant and the neoadjuvant cohorts, respectively, plus 2 treatment sequences with an early treatment withdrawal. The frequency of patients with ⩾1 hospital stay with a cardiac event was higher among patients with an early treatment withdrawal. Conclusions: The treatment sequences of most patients were in line with the recommendations in force. The machine learning approach provided a telling visual display of the results, thereby allowing healthcare professionals, health authorities, patients, and care givers to see the whole picture of the hospital-administered drug strategies.

[Where are done electrophysiology procedures in France and what is the expected evolution ?] / Où se fait l'activité de rythmologie interventionnelle en France et quelle est son évolution ?

INTRODUCTION: Interventional rhythmology activity (electrophysiology and pacing) has progressed in France during the last decade. The objective of this article was to assess the distribution of this activity depending on the type of centre (public, university or non-university, private). As the French government issued a new regulation regarding rhythmology activity in 2022, the impact of this regulation on activity distribution has been evaluated. METHODOLOGY: All French data activity can be evaluated after accessing to a national database called PMSI [Programme de médicalisation des systèmes d'information]. Based on data collected in year 2019, the level of activity of the different centres, and the impact of the new criteria of the French regulation regarding rhythmology activity have been analysed. RESULTS: About 180,000 arrhythmias interventions have been done in France in 2019 in 377 centres. According to the new criteria of the French regulation, only 76% responded to level A (diagnostic electrophysiology, single- and dual-chamber pacing), 52% for level B (A+ right atrial ablation, implantable automatic defibrillator, cardiac resynchronisation therapy) and 54% for level C (B + left atrial and ventricular ablation). CONCLUSIONS: This work showed that approximately a quarter of the centres do not meet criteria for level A activity, and approximately half of them for levels B and C. The priority will be to reinforce existing centres before allowing new centres to perform arrhythmias management activity in France.

Characteristics associated with the residual risk of severe COVID-19 after a complete vaccination schedule: A cohort study of 28 million people in France.

Background: Prior to the availability of vaccines, the risk factors for developing severe forms of COVID-19 were mostly older age and various comorbidities such as diabetes, cardiovascular diseases, mental disorders, transplantations, and kidney disease. Although vaccines have been shown to be highly effective in preventing severe forms of COVID-19, a residual risk may persist, despite vaccination, for certain population groups. Methods: The study was based on data from the national COVID-19 vaccination database (VAC-SI) coupled with the National Health Data System (SNDS), which contains comprehensive reimbursement and hospitalisation data for all of France. All people fully vaccinated by July 31, 2021, with a double-injection vaccine, i.e., the mRNA BNT162b2, mRNA-1273, or ChAdOx1 nCoV-19 vaccines, or a single dose for people with a previous confirmed SARS-CoV-2 infection were included and followed until August 31, 2021. Cox proportional hazard models were performed to estimate adjusted hazard ratios (aHR) for COVID-19-related hospitalisation or in-hospital death associated with age, gender, deprivation index, comorbidities, and immunosuppressive or oral corticosteroid therapy from day 14 after full-vaccination. Findings: In a population of 28,031,641 fully vaccinated individuals with an average follow-up of 80 days, 5,345 (87 hospitalisations per 100,000 person-years) were hospitalised for COVID-19 and 996 (16 in-hospital death per 100,000 person-years) died in hospital. In multivariable analysis, a higher risk was observed with increasing age, male gender, and social deprivation. Most of the 47 chronic conditions considered were positively associated with an increased risk of COVID-19-related hospitalisation and a slight excess risk of death. The risk of hospitalisation and in-hospital death for COVID-19 also increased with the use of immunosuppressants (aHR 3.3 [2.8-3.8] and 2.4 [1.7-3.5], respectively) and oral corticosteroids (aHR 2.8 [2.5-3.1] and 4.1 [3.3-5.1]).Less than 10% (519/5,345) of hospitalised cases and 2% (24/996) of those who died in hospital had no identified comorbidities. There was a strong association between an increasing number of comorbidities and the risk of hospitalisation and in-hospital death (e.g., 5+ versus none, aHR 10.1 95%CI 9.0-11.5 and 17.8 95%CI 11.5-27.4, respectively). Interpretation: Although vaccination has dramatically reduced the occurrence of severe forms of COVID-19, a residual risk remains for the elderly, immunocompromised, and polypathological populations and warrants complementary preventive measures. Funding: None.

How do Paraspinal Muscles Contract during the Schroth Exercise Treatment in Patients with Adolescent Idiopathic Scoliosis (AIS)?

The Schroth exercise can train the paraspinal muscles of patients with adolescent idiopathic scoliosis (AIS), however, muscle performance during the training remains unknown. This study applied surface electromyography (sEMG) to investigate the paraspinal muscle activities before, during and after Schroth exercise in nine AIS patients. This study found that after the Schroth exercise, the paraspinal muscle symmetry index (PMSI) was significantly reduced (PMSI = 1.3), while symmetry exercise significantly lowered the PMSI (PMSI = 0.93 and 0.75), and asymmetric exercise significantly increased the PMSI (PMSI = 2.56 and 1.52) compared to relax standing (PMSI = 1.36) in participants (p < 0.05). Among the four exercises, the PMSI of on all fours (exercise 1) and kneeling on one side (exercise 3) was the most and the least close to 1, respectively. The highest root mean square (RMS) of sEMG at the concave and convex side was observed in squatting on the bar (exercise 2) and sitting with side bending (exercise 4), respectively. This study observed that the asymmetric and symmetric exercise induced more sEMG activity on the convex and concave side, respectively, and weight bearing exercise activated more paraspinal muscle contractions on both sides of the scoliotic curve in the included AIS patients. A larger patient sample size needs to be investigated in the future to validate the current observations.

Patient healthcare trajectories of intrahepatic cholangiocarcinoma in France: A nationwide retrospective analysis.

BACKGROUND: Little is known about the epidemiology and patterns of care of intrahepatic cholangiocarcinoma (iCCA) in daily clinical practice. The aims of this study were to estimate the number of declared cases during the study period 2014-2015 in France from a hospitalization database and to describe the healthcare trajectories of these patients. METHODS: A retrospective analysis was carried out using the French nationwide prospective hospitalization database. All pts with a new diagnosis of "carcinoma of the intrahepatic bile duct" who had a first hospital stay in the Medicine, Surgery and Obstetrics departments (MSO) between 2014 and 2015 with a 2-year follow-up were included. Data related to the first identified stay (S1) in the MSO and on all subsequent stays in the MSO, aftercare and rehabilitation or home hospitalization were analysed. FINDINGS: A total of 3650 new iCCA cases were identified. At S1 (admission via emergency room (ER) in 28%), the median age of the patients was 73 years, 57% were male and 35% had metastases. Jaundice/anaemia/ascites/cholangitis were reported in 17%/16%/12%/7% of patients, respectively. The care of patients at S1 was mainly provided in general hospitals (CHG, 60%). A total of 896 (24%) patients died during S1. They were more frequently hospitalized via the ER (48% vs 23%), metastatic (52% vs 35%) and symptomatic. Subsequent stays were identified for 2507 (69%) patients. Three healthcare pathways were defined: surgery (n = 519; 14%), chemotherapy (CT) without surgery (n = 812; 22%) and best supportive care (BSC) (n = 2319; 63%). CT, surgery and BSC were most frequently performed in the cancer centres, university hospitals and CHG, respectively. INTERPRETATION: This medico administrative study reveals a higher number of iCCA cases than that previously reported by registries and highlights the severity of this disease. FUNDING: This study was sponsored by Incyte Biosciences International Sàrl., Geneva, Switzerland. INCYTE validated the design of the study, the analysis, the interpretation of data and the writing of the manuscript which was first written by the 2 experts and CEMKA.

Risk factors for and characteristics of community- and hospital-acquired drug-induced acute kidney injuries.

Drugs constitute one of the leading causes of acute kidney injuries (AKIs) and can appear in community (CA-AKI) or hospital (HA-AKI) population. The objectives of the present study of a cohort of hospitalized patients with AKI were to describe the characteristics of drug-induced AKIs and the patients' short-term outcomes and assess risk factors for drug-induced AKIs overall, CA-AKIs, and HA-AKIs. Based on a cohort of 1557 hospitalized patients suffering from AKIs based on PMSI extraction and chart review (IRA-PMSI), drug-induced AKIs were identified by applying the Naranjo adverse drug reaction (ADR) probability scale. Multivariate logistic regression was used to identify factors associated with CA-AKIs and/or HA-AKIs. When considering the 1557 patients who experienced an AKI, 445 (28.6%) of the injuries were drug-induced (180 CA-AKIs (40.4%) and 265 HA-AKIs (59.6%)). Antibiotics, diuretics, and contrast agents were significantly more likely to be involved in HA-AKIs, whereas antineoplastic, lipid-lowering drugs, antidiabetics, and immunosuppressive were significantly more likely to be involved in CA-AKIs. Female sex (odds ratio [OR] [95%CI] = 1.3 [1.04-1.67]), chronic kidney disease (CKD) (OR = 1.8 [1.40-2.67]), and a history of ADRs of any type (OR = 1.3 [1.05-1.73]) were significant risk factors for drug-induced AKIs. CKD was a risk factor for both CA-AKI and HA-AKI. In view of the long-term impact of AKI on the kidneys and the differences between our CA-AKI and HA-AKI subgroups, our present results are interesting for optimizing treatments, limiting the occurrence of CA- and HA-AKIs and (ultimately) reducing healthcare costs.

Association between increased mortality and bronchial fibroscopy in intensive care units and intermediate care units during COPD exacerbations: an analysis of the 2014 and 2015 National French Medical-based Information System Databases (PMSI).

BACKGROUND: The course of chronic obstructive pulmonary disease (COPD) is punctuated by exacerbations, most often of infectious origin, responsible for many intensive care unit (ICU) and intermediate care unit (IMCU) admissions. Our objective was to study in-hospital mortality during severe COPD exacerbations in ICU and IMCU based on the performance of bronchoscopy. METHODS: A retrospective analysis was carried out on stays in ICUs for COPD exacerbation from the French Programme for the Medicalisation of Information Systems databases for the years 2014 and 2015. Propensity score matching of stays made it possible to constitute two comparable groups on the factors of excess mortality described in the literature (age, sex, SAPS 2, type of admission and bronchial tumour). RESULTS: We identified 14,491 stays for COPD exacerbation in ICUs, 2586 of which received a bronchoscopy. Mortality was significantly higher in the fibroscopy group (31.32% versus 19.8%). After propensity score matching, we found an excess of mortality in the intervention group (OR = 1.749 [1.516-2.017]) associated with a significantly longer length of stay. The main diagnoses associated with an increased risk of death were pulmonary embolism (OR = 3.251 [1.126-9.384]), bacterial pneumonia (OR = 1.906 [1.173-3.098]) and acute respiratory failure (OR = 1.840 [1.486-2.278]). CONCLUSIONS: Performing bronchoscopy during ICU hospitalisations for severe COPD exacerbations was associated with increased mortality. This increased mortality appears to be related to a bias in patient selection with a procedure reserved for patients with the adverse course.

[Linking Interventional Cardiology clinical registry data with French hospital administrative data: Development and validation of deterministic record linkage]. / Appariement entre un registre régional de pratiques en cardiologie interventionnelle et la base médico-administrative d'hospitalisation française : développement et validation d'un algorithme d'appariement déterministe.

BACKGROUND: To recreate the in-hospital healthcare pathway for patients treated with coronary angiography or percutaneous coronary intervention, we linked the interventional cardiology registry (ACIRA) and the pseudonymized French hospital medical information system database (PMSI) in the Aquitaine region. The objective of this study was to develop and validate a deterministic merging algorithm between these exhaustive and complementary databases. METHODS: After a pre-treatment phase of the databases to standardize the 11 identified linking variables, a deterministic linking algorithm was developed on ACIRA hospital stays between December 2011 and December 2014 in nine interventional cardiology centers as well as the data from the consolidated PMSI databases of the Aquitaine region from 2011 to 2014. Merging was carried out through 12 successive steps, the first consisting in strict linking of the 11 variables. The performance of the algorithm was analyzed in terms of sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV). Strategies complementary to the initial algorithm (change in the order of variables and base preprocessing) were tested. Comparative analysis of merged/unmerged patients explored potential causes of mismatch. RESULTS: The algorithm found 97.2% of the 31,621 ACIRA stays to have sensitivity of 99.9% (95% CI [99.9; 99.9]), specificity of 97.9% (95% CI [97.7; 98.1]), PPV of 99.9% (95% CI [99.9; 99.9]) and NPV of 96.9% (95% CI [96.7; 97.1]). Complementary strategies did not yield better results. The unmerged patients were older, and hospitalized mostly in 2012 in two interventional cardiology centers. CONCLUSION: This study underscored the feasibility and validity of an indirect deterministic pairing to routinely link a registry of practices using hospital data to pseudonymized medico-administrative databases. This method, which can be extrapolated to other health events leading to hospitalization, renders it possible to effectively reconstruct patients' hospital healthcare pathway.

Effectiveness of a French Program to Prevent Suicide Reattempt (VigilanS).

AIM: Brief contact interventions (such as letters, green cards, telephone calls or postcards) for reducing suicide reattempt (SR) and suicide have been evaluated since the 1980s, but results have been inconsistent. VigilanS is one of these programs that has benefited patients hospitalized for suicide attempt (SA) after discharge in 2 departments of northern France since 2015. The purpose of this study is to demonstrate its effectiveness in reducing SR. METHODS: Patients exposed to VigilanS in 2016 were recruited from the medical administrative database of the program, and the nonexposed patients from a database of the medico-surgical ward outside the scope of the program. First, a Cox model was used to compare the probability of SR during the 12-month follow-up period between the 2 groups. Second, a propensity score using the variables sex, age, source, SA history and SA method was used to match the VigilanS-exposed and the nonexposed patients. A Cox model propensity score adjusted analysis was reiterated on the matched data. RESULTS: The exposed and nonexposed groups included 3,068 and 3,694 individuals, respectively. In the bivariate analyses, the cumulative probability of SR at 12 months was significantly lower in the exposed group (6.0%, 95% confidence interval (CI): 5.5-6.5%) than in the nonexposed group (16.8%, 95% CI: 15.9-17.7%; p < 0.001). In the Cox model, the hazard ratio of SR was 0.38 in the exposed patients (95% CI: 0.36-0.40, p < 0.001). After matching, the cumulative probability of SR at 12 months was 5.2% in exposed versus 22.2% in nonexposed patients (p < 0.001). In the propensity score-adjusted Cox model, the hazard ratio of SR in the exposed patients was 0.19 (95% CI: 0.14-0.24, p < 0.001). CONCLUSION: The results suggest the effectiveness of this real-life program for reducing SR. However, VigilanS only benefits a portion of the patients hospitalized for SA and therefore could be extended.
