RESUMO
No other organ in the human body has as many functions as the skin-biologic, cultural, social, and psychologic. The skin is the first attribute we notice, and it is the basis of our first impressions. It provides information about our state of health, our moods, our age, and sometimes our cultural background. Above all, the skin is an organ like the heart or the lungs. The objective of this exploratory anthropologic study was to shed light on the people's global perception of the skin. More precisely, we wanted to explore how people think about their skin and whether they think of it in terms of its biologic role and importance as their body's largest organ. We wanted to know how aware they are about the skin's anatomy, functionality, and the pathologies that most concern them. Do people consider their skin merely as an envelope of beauty or as something more? To find out, we conducted a prospective anthropologic study of a random sampling of multicultural individuals in and around Paris, France. Participants were given a questionnaire with six semi-structured questions and one open-ended question about their per-ceptions and attitudes of their skin. Responses were analyzed on the basis of word groupings within the six major categories of considerations represented by the available literature on the skin in both French and English. The results of this study demonstrated the mutable nature of people's perception of their skin. Rather than remaining with one fixed vision, their thoughts about their skin changed in conjunction with their age, life experiences, and lifestyle in accordance with wider societal and environmental realities. In addition, their perspectives tended to go beyond cultural groupings, displaying a certain homogeneity of vision across demographic categories. As such, we concluded that the skin is a form of virtual reality that is constructed and reconstructed as one moves through life in the society.

Heatwaves and soil droughts are increasing in frequency and intensity, leading many tree species to exceed their thermal thresholds, and driving wide-scale forest mortality. Therefore, investigating heat tolerance and canopy temperature regulation mechanisms is essential to understanding and predicting tree vulnerability to hot droughts. We measured the diurnal and seasonal variation in leaf water potential (Ψ), gas exchange (photosynthesis Anet and stomatal conductance gs), canopy temperature (Tcan), and heat tolerance (leaf critical temperature Tcrit and thermal safety margins TSM, i.e., the difference between maximum Tcan and Tcrit) in three oak species in forests along a latitudinal gradient (Quercus petraea in Switzerland, Quercus ilex in France, and Quercus coccifera in Spain) throughout the growing season. Gas exchange and Ψ of all species were strongly reduced by increased air temperature (Tair) and soil drying, resulting in stomatal closure and inhibition of photosynthesis in Q. ilex and Q. coccifera when Tair surpassed 30°C and soil moisture dropped below 14%. Across all seasons, Tcan was mainly above Tair but increased strongly (up to 10°C > Tair) when Anet was null or negative. Although trees endured extreme Tair (up to 42°C), positive TSM were maintained during the growing season due to high Tcrit in all species (average Tcrit of 54.7°C) and possibly stomatal decoupling (i.e., Anet ≤0 while gs >0). Indeed, Q. ilex and Q. coccifera trees maintained low but positive gs (despite null Anet), decreasing Ψ passed embolism thresholds. This may have prevented Tcan from rising above Tcrit during extreme heat. Overall, our work highlighted that the mechanisms behind heat tolerance and leaf temperature regulation in oak trees include a combination of high evaporative cooling, large heat tolerance limits, and stomatal decoupling. These processes must be considered to accurately predict plant damages, survival, and mortality during extreme heatwaves.

PURPOSE: Meningeal solitary fibrous tumour (SFT) and haemangiopericytoma (HPC) are uncommon tumours that have been merged into a single entity in the last 2021 WHO Classification of Tumors of the Central Nervous System. To describe the epidemiology of SFT/HPC operated in France and, to assess their incidence. METHODS: We processed the French Brain Tumour Database (FBTDB) to conduct a nationwide population-based study of all histopathologically confirmed SFT/HPC between 2006 and 2015. RESULTS: Our study included 399 SFT/HPC patients, operated in France between 2006 and 2015, in one of the 46 participating neurosurgical centres. The incidence reached 0.062, 95%CI[0.056-0.068] for 100,000 person-years. SFT accounted for 35.8% and, HPC for 64.2%. The ratio of SFT/HPC over meningioma operated during the same period was 0.013. SFT/HPC are about equally distributed in women and men (55.9% vs. 44.1%). For the whole population, mean age at surgery was 53.9 (SD ± 15.8) years. The incidence of SFT/HPC surgery increases with the age and, is maximal for the 50-55 years category. Benign SFT/HPC accounted for 65.16%, SFT/HPC of uncertain behaviour for 11.53% and malignant ones for 23.31%. The number of resection progresses as the histopathological behaviour became more aggressive. 6.7% of the patients with a benign SFT/HPC had a second surgery vs.16.6% in case of uncertain behaviour and, 28.4% for malignant SFT/HPC patients. CONCLUSION: Meningeal SFT and HPC are rare CNS mesenchymal tumours which both share common epidemiological characteristics, asserting their merging under a common entity. SFT/HPC incidence is less that one case for 1 billion per year and, for around 100 meningiomas-like tumours removed, one SFT/HPC may be diagnosed. SFT/HPC are equally distributed in women and men and, are mainly diagnosed around 50-55 years. The more aggressive the tumour, the higher the probability of recurrence.

Nutrient enrichment and climate warming threaten freshwater systems. Metabolic theory and the paradox of enrichment predict that both stressors independently can lead to simpler food-webs having fewer nodes, shorter food-chains and lower connectance, but cancel each other's effects when simultaneously present. Yet, these theoretical predictions remain untested in complex natural systems. We inferred the food-web structure of 256 lakes and 373 streams from standardized fish community samplings in France. Contrary to theoretical predictions, we found that warming shortens fish food-chain length and that this effect was magnified in enriched streams and lakes. Additionally, lakes experiencing enrichment exhibit lower connectance in their fish food-webs. Our study suggests that warming and enrichment interact to magnify food-web simplification in nature, raising further concerns about the fate of freshwater systems as climate change effects will dramatically increase in the coming decades.

As other European countries, France is experiencing a resurgence of pertussis in 2024. Between 1 January and 31 May 2024, 5,616 (24.9%) positive Bordetella pertussis qPCR tests were identified, following a 3-year period of almost null incidence. Of 67 cultured and whole genome sequenced B. pertussis isolates, 66 produced pertactin and 56 produced FIM2, in contrast to pre-COVID-19 years. One isolate of genotype Bp-AgST4 was resistant to macrolides. Pertussis resurgence may favour isolates that produce FIM2 and pertactin.

BACKGROUND: Type 2 diabetes is one of the most prevalent and preventable diseases worldwide and impulsivity, a psychological trait characterized by making quick decisions without forethought, has been suggested as a key feature for health-related conditions. However, there have been no studies examining the relationships between impulsivity and the incidence of type 2 diabetes and our aim was to assess the prospective association between trait impulsivity and the risk of developing type 2 diabetes. METHODS: A prospective observational study design was conducted between May 2014 and February 2023 within the NutriNet-Santé cohort. A web-based platform was used to collect data from the French adult population, with voluntary enrollment and participation. Of the 157,591 adults (≥ 18 years old) participating in the NutriNet-Santé study when impulsivity was assessed, 109,214 participants were excluded due to prevalent type 1 or 2 diabetes or missing data for impulsivity or follow-up data for type 2 diabetes. Trait impulsivity, and the attention, motor, and non-planning subfactors, were assessed at baseline using the Barratt Impulsiveness Scale 11. Incident type 2 diabetes was ascertained through follow-up. Medical information was reviewed by NutriNet-Santé physician experts to ascertain incident diabetes cases based on the ICD-10. Cox regression models, using hazard ratios and 95% confidence intervals (HR [95% CI]), were performed to evaluate associations between impulsivity per 1 standard deviation increment and type 2 diabetes risk, adjusting by recognized confounders. RESULTS: Of the 48,377 individuals studied (women 77.6%; age at baseline = 50.6 year ± 14.5 years), 556 individuals developed type 2 diabetes over a median follow-up of 7.78 (IQR: 3.97-8.49) years. Baseline impulsivity was associated with an increased risk of type 2 diabetes incidence (HR = 1.10 [1.02, 1.20]). The motor impulsivity subfactor was positively associated with type 2 diabetes risk (HR = 1.14 [1.04, 1.24]), whereas no associations were found for attention and non-planning impulsivity subfactors. CONCLUSIONS: Trait impulsivity was associated with an increased type 2 diabetes risk, mainly driven by the motor impulsivity subfactor. If these results are replicated in other populations and settings, trait impulsivity may become an important psychological risk factor to be considered in the prevention of type 2 diabetes.

BACKGROUND: The main objective of this study was to undertake an exhaustive investigation of sex-related differences in cancer surgery. METHODS: This observational study used data from the French national health insurance system database covering 98.8% of the population. Patients diagnosed with non-sex-specific solid invasive cancers between January 2018 and December 2019 were included. The main outcomes were likelihood of undergoing cancer surgery, type of oncological surgery performed, and associated 30-, 60-, and 90-day postoperative reoperation and mortality rates, by sex. RESULTS: For the 367 887 patients included, women were 44% more likely than men to undergo cancer surgery (OR 1.44, 95% c.i. 1.31 to 1.59; P < 0.001). However, the likelihood of surgery decreased with advancing age (OR 0.98, 0.98 to 0.98; P < 0.001), and with increasing number of co-morbid conditions (OR 0.95, 0.95 to 0.96; P < 0.001), especially in women. Men had higher 90-day reoperation (21.2 versus 18.8%; P < 0.001) and mortality (1.2 versus 0.9%; P < 0.001) rates than women, overall, and for most cancer types, with the exception of bladder cancer, for which the 90-day mortality rate was higher among women (1.8 versus 1.4%; P < 0.001). After adjustment for age, number of co-morbid conditions, and surgical procedure, 90-day mortality remained higher in men (OR 1.16, 1.07 to 1.26; P < 0.001), and men were 21% more likely than women to undergo reoperation within 90 days (OR 1.21, 1.18 to 1.23; P < 0.001). CONCLUSION: Women were much more likely than men to undergo cancer surgery than men, but the likelihood of surgery decreased with advancing age and with increasing number of co-morbid conditions, especially in women. These findings highlight a need for both increased awareness and strategies to ensure gender equality in access to oncological surgical treatment and improved outcomes.

OBJECTIVES: The gastrointestinal tract (GIT) is frequently involved in systemic sclerosis (SSc) and is responsible for alteration of quality of life. Many complications can occur, including chronic intestinal pseudo-obstruction, digestive haemorrhage and small-intestinal bacterial overgrowth. Since early development of organ failure is associated with poor prognosis, we need to identify risk factors associated with severe GIT involvement to prevent severe forms of the disease. METHODS: We conducted an observational prospective study, which included 90 SSc patients from December 2019 to September 2021. We collected questionnaires about digestive manifestations and quality of life, blood and stool samples, and performed imaging. At inclusion and throughout the study we assessed the occurrence of malnutrition and severe GIT disorders. We performed statistical analysis to highlight eventual risk factors associated with digestive manifestations, including hierarchical cluster analysis. RESULTS: A majority of our patients had gastro-oesophageal manifestations (93.3%), followed by intestinal manifestations (67.8%) and anorectal manifestations (18.9%). We found a correlation between anorectal disorders and cardiac disease, and between gastro-oesophageal involvement and impaired pulmonary function tests. Smoking was significantly associated with occurrence of severe GIT disorders. Malnutrition was frequent and associated with more cardiac and pulmonary disease. Cluster analysis identified three groups of patients, including one cluster with cardiac and digestive involvement. CONCLUSIONS: GIT manifestations are frequent and severe in SSc. Smoking appears to be associated with severe disease. Anorectal manifestations may be associated with cardiac disease, but we need more studies to validate these results.

BACKGROUND Lung transplantation (LTx) is a life-extending therapy for specific patients with terminal lung diseases. This study aimed to evaluate the associations and causes of 1-year mortality after lung transplantation at Strasbourg University Hospital, France, between 2012 and 2021. MATERIAL AND METHODS We carried out a retrospective analysis on 425 patients who underwent LTx at Strasbourg University Hospital between January 1, 2012, and December 31, 2021. Pre-transplant, perioperative, and postoperative data were collected from the electronic medical records. RESULTS Among all patients, 94.6% had a LTx, 4.0% a heart-lung transplantation, and 1.4% underwent pancreatic islet-lung transplantation. The median age at transplantation was 57 years, with 55.3% male patients. The main native lung disease leading to LTx was chronic obstructive pulmonary disease in 51.1% of patients; 16.2% needed super-urgent LTx. The 1-year mortality rate was 11.5%. Most deaths were either caused by multi-organ failure or septic shock. In our multivariate analysis, we identified 3 risk factors significantly related to 1-year mortality after LTx: body mass index (BMI) between 25 and 30 kg/m² vs BMI between 18.5 and 25 kg/m² (P=0.032), postoperative extracorporeal membrane oxygenation support (P=0.034), and intensive care unit length of stay after transplantation (P<0.001). Two other factors were associated with a significantly lower 1-year mortality risk: longer hospital stay after LTx (P=0.024) and tacrolimus prescription (P=0.004). CONCLUSIONS Our study reported a 1-year mortality rate of 11.5% after LTx. Although LTx candidates are carefully selected, additional data are required to improve understanding of the risk factors for post-LTx mortality.

Climate change is increasing the proportion of river networks experiencing flow intermittence, which in turn reduces local diversity (i.e., α-diversity) but enhances variation in species composition among sites (i.e., ß-diversity), with potential consequences on ecosystem stability. Indeed, the multiscale theory of stability proposes that regional stability can be attained not only by local processes but also by spatial asynchrony among sites. However, it is still unknown whether and how scale-dependent changes in biodiversity associated with river flow intermittence influence stability across spatial scales. To elucidate this, we here focus on multiple metacommunities of French rivers experiencing contrasting levels of flow intermittence. We clearly show that the relative contribution of spatial asynchrony to regional stability was higher for metacommunities of intermittent than perennial rivers. Surprisingly, spatial asynchrony was mainly linked to asynchronous population dynamics among sites, but not to ß-diversity. This finding was robust for both truly aquatic macroinvertebrates and for taxa that disperse aerially during their adult stages, implying the need to conserve multiple sites across the landscape to attain regional stability in intermittent rivers. By contrast, metacommunities of truly aquatic macroinvertebrates inhabiting perennial rivers were mainly stabilized by local processes. Our study provides novel evidence that metacommunities of perennial and intermittent rivers are stabilized by contrasting processes operating at different spatial scales. We demonstrate that flow intermittence enhances spatial asynchrony among sites, thus resulting in a regional stabilizing effect on intermittent river networks. Considering that climate change is increasing the proportion of intermittent rivers worldwide, our results suggest that managers need to focus on the spatial dynamics of metacommunities more than on local-scale processes to monitor, restore, and conserve freshwater biodiversity.

OBJECTIVE: Managing the gap between the dressing and the wound bed can facilitate the healing of exuding wounds. A silicone foam dressing (Biatain Silicone; Coloplast A/S, Denmark) was developed for application to exuding wounds. A sub-analysis of the real-world, prospective, observational VIPES (Observatoire en Ville des Plaies ExSudatives) study was conducted to investigate the use and performance of the silicone foam dressing in a community nursing setting in France. METHOD: The sub-analysis included patients from the VIPES study who received the silicone foam dressing as a primary dressing for an acute or hard-to-heal (chronic) wound. Epidemiological and wound healing outcomes were reported via a smartphone application. RESULTS: Overall, 64 patients were included in the sub-analysis. At baseline, most wounds (n=33/40; 82.5%) were in treatment failure (i.e., were stagnant, non-healing or had poor exudate management). At the last follow-up visit, a median of 22.5 (range: 3-151) days post baseline, 48.4% of wounds had healed and 25.0% were progressing towards healing. From baseline to the last follow-up visit, significant reductions in exudate level (p<0.0001) and exudate pooling (p<0.0001), and significant improvements in wound edges (p≤0.0001) and periwound skin (p<0.01) were observed. A total of 62.3% of patients had re-epithelialising wounds at the last follow-up visit. The majority of nurses (88.3%) and patients (85.0%) reported that the wound had improved and, at most dressing removals (93.5%), nurses reported that the dressing conformed closely to the wound bed. CONCLUSION: Overall, the data suggest that use of the silicone foam dressing in community practice supported the healing of wounds, illustrating the importance of exudate and gap management.

BACKGROUND: Most the Organization for Economic Co-operation and Development (OECD) countries are currently facing the challenges of the health transition, the aging of their populations and the increase in chronic diseases. Effective and comprehensive primary healthcare (PHC) services are considered essential for establishing an equitable, and cost-effective healthcare system. Developing care coordination and, on a broader scale, care integration, is a guarantee of quality healthcare delivery. The development of healthcare systems at the meso-level supports this ambition and results in a process of territorial structuring of PHC. In France, the Health Territorial and Professional Communities (HTPC) constitute meso-level organizations in which healthcare professionals (HCPs) from the same territory gather. We conducted a study to determine, in a qualitative step, the key elements of the territorial structuring of PHC in France and, then, to develop, in a quantitative step, a typology of this structuring. METHODS: A sequential-exploratory mixed-method study with a qualitative step using a multiple case approach and a quantitative step as a hierarchical clustering on principal components (HCPC) from a multiple correspondence analysis (MCA). RESULTS: A total of 7 territories were qualitatively explored. Territorial structuring appears to depend on: past collaborations at the micro-level, meso-level coordination among HCPs and multiprofessional structures, diversity of independent professionals, demographic dynamics attracting young professionals, and public health investment through local health contracts (LHCs). The typology identifies 4 clusters of mainland French territories based on their level of structuring: under or unstructured (38.6%), with potential for structuring (34.7%), in the way for structuring (25.3%) and already structured territories (1.4%). CONCLUSION: Interest in territorial structuring aligns with challenges in meso-level healthcare organization and the need for integrated care. Typologies of territorial structuring should be used to understand its impact on access, care quality, and medical resources.

Global changes in climate are contributing to modified Phlebotomine sand fly presence and activity, and the distribution of the pathogens they transmit (e.g., Leishmania and Phlebovirus), and are leading to their possible extension toward northern France. To predict the evolution of these pathogens and control their spread, it is essential to identify and characterize the presence and abundance of potential vectors. However, there are no recent publications describing sand fly species distribution in France. Consequently, we carried out a systematic review to provide distribution and abundance maps over time, along with a simplified dichotomous key for species in France. The review adhered to PRISMA guidelines, resulting in 172 relevant capture reports from 168 studies out of the 2646 documents retrieved, of which 552 were read and 228 analyzed. Seven species were recorded and categorized into three groups based on their abundance: low abundance species, abundant but little-studied species, and abundant vector species. Sand flies are certainly present throughout France but there is a greater diversity of species in the Mediterranean region. Phlebotomus perniciosus and Ph. ariasi are the most abundant and widely distributed species, playing a role as vectors of Leishmania. Sergentomyia minuta, though very abundant, remains under-studied, highlighting the need for further research. Phlebotomus papatasi, Ph. perfiliewi, Ph. sergenti, and Ph. mascittii are present in low numbers and are less documented, limiting understanding of their potential role as vectors. This work provides the necessary basis for comparison of field data generated in the future.
Title: Répartition et abondance des phlébotomes en France : revue systématique. Abstract: Les changements globaux du climat contribuent à modifier la présence et l'activité des phlébotomes, ainsi que la répartition des pathogènes qu'ils transmettent (par exemple Leishmania et Phlebovirus), et conduisent à leur éventuelle extension vers le nord de la France. Pour prédire l'évolution de ces pathogènes et contrôler leur propagation, il est essentiel d'identifier et de caractériser la présence et l'abondance des vecteurs potentiels. Il n'existe cependant aucune publication récente décrivant la répartition des espèces de phlébotomes en France. Par conséquent, nous avons réalisé une revue systématique pour fournir des cartes de répartition et d'abondance dans le temps, ainsi qu'une clé dichotomique simplifiée pour les espèces françaises. La revue a respecté les lignes directrices PRISMA, aboutissant à 172 rapports de capture pertinents provenant de 168 études sur les 2 646 documents récupérés, dont 552 ont été lus et 228 analysés. Sept espèces ont été recensées et classées en trois groupes en fonction de leur abondance : les espèces de faible abondance, les espèces abondantes mais peu étudiées et les espèces vectrices abondantes. Les phlébotomes sont certes présents partout en France mais on trouve une plus grande diversité d'espèces dans le bassin méditerranéen. Phlebotomus perniciosus et Ph. ariasi sont les espèces les plus abondantes et les plus largement réparties, jouant un rôle de vecteurs de Leishmania. Sergentomyia minuta, bien que très abondant, reste sous-étudié, ce qui souligne la nécessité de recherches plus approfondies. Phlebotomus papatasi, Ph. perfiliewi, Ph. sergenti et Ph. mascittii sont présents en faibles nombres et sont moins documentés, ce qui limite la compréhension de leur rôle potentiel en tant que vecteurs. Ce travail fournit la base nécessaire pour la comparaison des données de terrain générées à l'avenir.

INTRODUCTION: The independent French drug bulletin Prescrire International rates the therapeutic innovation of new drug-indications approved for marketing in France using an ordinal scale with the lowest rating being "not acceptable". This study investigates whether these drugs were approved by Health Canada. METHODS: A list of "not acceptable" drug-indications was generated by handsearching all issues of Prescrire International between January 2013 and December 2022. The generic names, indications and reasons why Prescrire labeled them not acceptable were recorded. The approval date was determined by consulting the website of the European Medicines Agency (EMA). The status of these drug-indications in Canada was determined by searching multiple Health Canada websites. Therapeutic Evaluations for new drug-indications done by the Patented Medicine Prices Review Board (PMPRB) were recorded. RESULTS: Prescrire rated 57 new drug-indications and 42 new indications for existing drugs as not acceptable. Seventy of these drug-indications were available in Canada- 42 new drug-indications and 28 new indications for existing drugs. Twenty (90.9%) of the 22 new drugs evaluated by the PMPRB were rated as slight/no therapeutic improvement and 2 as moderate therapeutic improvement. The median difference, in days, between approval times by the EMA/ANSM and Health Canada was 129 (interquartile range -102, 341) in favour of the former. DISCUSSION: The majority of the not acceptable drug-indications were approved by Health Canada. The difference between when Prescrire and Health Canada examined the evidence for these drug-indications is unlikely to explain the difference in their evaluations. A change in regulatory standards at Health Canada may be one factor behind the presence of these drugs. To what degree those drugs led to more harms than benefits for patients who are taking them needs to be urgently investigated. Finally, the reasoning behind Health Canada's approval of these drugs should be interrogated.

Cancer is associated with a hypercoagulable state and is a well-known independent risk factor for venous thromboembolism, whereas the association between cancer and arterial thromboembolism is less well established. Arterial thromboembolism, primarily defined as myocardial infarction or stroke is significantly more frequent in patients with cancer, independently of vascular risk factors and associated with a three-fold increase in the risk of mortality. Patients with brain cancer, lung cancer, colorectal cancer and pancreatic cancer have the highest relative risk of developing arterial thromboembolism. Antithrombotic treatments should be used with caution due to the increased risk of haemorrhage, as specified in current practice guidelines.

This article details how the French army employed medical topography as a tool of military occupation throughout the Mediterranean world from the mid-eighteenth to mid-nineteenth century. It departs from other works by focusing exclusively on medical topography's military applications. Medical topographies charted the connections between health and the environment by observing a location's features, such as soil, air, and water quality, as well as elevation, prevailing winds, common local diseases, sources of potential contagion, and the cleanliness of urban environments. Because a medical-topographic study took time to write and implement, its findings provided little utility during active conflict. Only after the fighting ceased during a campaign could the army make use of a medical topography's findings by taking measures such as draining swamps, relocating hospitals in unhealthy environments, and issuing climate-appropriate gear.
Cet article examine la façon dont l'armée française utilisait la topographie médicale en tant qu'outil d'occupation militaire pendant les dix-huitième et dix-neuvième siècles dans le monde Méditerranéen. Il se détache des autres travaux en se concentrant exclusivement sur les applications militaires de l'étude. Les études topographiques-médicales analysaient des liens entre l'environnement et la santé. Ces études permettaient l'observation minutieuse et l'enregistrement des caractéristiques d'un lieu, comme par exemple : son élévation, les vents dominants, la qualité de terre, d'eaux, et d'air, la propreté des centres urbaines, et des maladies locales ainsi que leurs origines. Parce que ces études exigeaient du temps d'écrire et d'implémenter, elles n'ont pas eu une grande utilité pratique pendant une campagne. Cependant, après la cessation des hostilités, l'armée a mis en pratique les résultats de ces études. Elle a vidé des marais, déménagé des hôpitaux malsains, et distribué du matériel adapté à l'environnement.

OBJECTIVES: To assess the potential impact of targeted therapies for psoriatic arthritis (PsA) on symptomatic treatments (non-steroidal anti-inflammatory drugs (NSAIDs), corticosteroids, opioid analgesics), methotrexate and mood disorder treatments and on hospitalisation and sick leave. METHODS: Using the French health insurance database, this nationwide cohort study included adults with PsA who were new users (not in the year before the index date) of targeted therapies for ≥9 months during 2015-2021. Main endpoints were difference in proportion of users of associated treatments, hospitalisations and sick leaves between 3 and 9 months after and 6 months before targeted therapy initiation. Logistic regression models adjusted for sex, age, psoriasis, inflammatory bowel disease and Charlson Comorbidity Index compared the impact of biologics initiation (tumour necrosis factor inhibitor (TNFi)/interleukin 17 inhibitor (IL17i)/IL12/23i) on associated treatment discontinuation. RESULTS: Among 9793 patients initiating targeted therapy for PsA (mean age: 51±13 years, 47% men), 62% initiated TNFi, 14% IL17i, 10% IL12/23i, 1% Janus kinase inhibitor, 12% phosphodiesterase-4 inhibitor. After treatment initiation, the proportion of treatment users was significantly reduced for NSAIDs (-15%), opioid analgesics (-9%), prednisone (-9%), methotrexate (-15%) and mood disorder treatments (-2%), along with decreased hospitalisations (-12%) and sick leaves (-4%). TNFi had a greater sparing effect on NSAIDs and prednisone use than IL17i (ORa=1.04, 95% CI=1.01 to 1.07; 1.04, 1.02 to 1.06) and IL12/23i (1.07, 1.04 to 1.10; 1.06, 1.04 to 1.09). Odds of methotrexate discontinuation was reduced with TNFi versus IL17i (0.96, 0.94 to 0.98) and IL12/23i (0.94, 0.92 to 0.97). CONCLUSIONS: Targeted therapy initiation for PsA reduced the use of associated treatment and healthcare, with TNFi having a slightly greater effect than IL17i and IL12/23i, except for methotrexate discontinuation.

BACKGROUND: With recent advancements in the treatment of chronic lymphocytic leukemia (CLL) and mantle cell lymphoma (MCL), healthcare specialists may face challenges making treatment and management decisions based on latest evidence for the optimal care of patients with these conditions. This study aimed to identify specific knowledge, skills, and confidence gaps impacting the treatment of CLL and MCL, to inform future educational activities. METHODS: Hematologists and hemato-oncologists (HCPs, n = 224) from France (academic settings), Germany, and the United States (academic and community settings) responded to a 15-minute quantitative needs assessment survey that measured perceived knowledge, skills, and confidence levels regarding different aspects of treatment and management of CLL and MCL patients, as well as clinical case questions. Descriptive statistics (cross tabulations) and Chi-square tests were conducted. RESULTS: Four areas of educational need were identified: (1) sub-optimal knowledge of treatment guidelines; (2) sub-optimal knowledge of molecular testing to inform CLL/MCL treatment decisions; (3) sub-optimal skills when making treatment decisions according to patient profile (co-morbidities, molecular testing results); and (4) challenges balancing the risk of toxicities with benefits of treatment. Over one-third of the respondents reported skill gaps when selecting suitable treatment options and prescribing therapies and reported a lack in confidence to initiate and manage treatment. Larger gaps in knowledge of guidelines and skills in patient assessment were identified in MCL, compared to CLL. CONCLUSIONS: This study suggests the need for continuing medical education specifically to improve knowledge of treatment guidelines, and to assist clinicians in developing skills and confidence when faced with clinical decision-making scenarios of patients with specific comorbidities and/or molecular test results, for example, through case-based learning activities.

Rhegmatogenous retinal detachment (RRD) is a sight-threatening condition with rising global incidence. Identifying factors contributing to seasonal variations in RRD would allow a better understanding of RRD pathophysiology. We therefore performed a retrospective case series study investigating the relationship between RRD occurrence and meteorological factors throughout metropolitan France (the METEO-POC study), particularly the mean temperature over the preceding 10-day period (T-1). Adult patients having undergone RRD surgery and residing in one of the three most populated urban areas of each French region were included (January 2011-December 2018). The study involved 21,166 patients with idiopathic RRD (61.1% males, mean age 59.8-65.1 years). RRD incidence per 100,000 inhabitants increased from 7.79 to 11.81. RRD occurrence was not significantly associated with mean temperature over T-1 in the majority of urban areas (31/36). In a minority of areas (5/36) we observed correlations between RRD incidence and mean temperature over T-1, however these were extremely weak (r = 0.1-0.2; p < 0.05). No associations were found between RRD incidence and secondary outcomes: mean daily temperature over the 10 days prior T-1, minimum/maximum temperatures, rainfall, duration of sunshine, atmospheric pressure, overall radiation, relative humidity, wind speed. Overall, we found no relationships between meteorological parameters and RRD occurrence.

BACKGROUND: Incidence of complications following obstetrical anal sphincter injury (OASI) during vaginal delivery are poorly defined. They are only studied in high level maternities, small cohorts, all stages of perineal tear or in low-income countries. The aim of our study was to describe complications after primary OASI repair following a vaginal delivery in all French maternity wards at short and midterm and to assess factors associated with complication occurrence. METHODS: We conducted a historical cohort study using the French nationwide claim database (PMSI) from January 2013 to December 2021. All women who sustained an OASI repair following a vaginal delivery were included and virtually followed-up for 2 years. Then, we searched for OASIS complications. Finally, we evaluated factors associated with OASIS complication repaired or not and OASIS complication repairs. RESULTS: Among the 61,833 included women, 2015 (2.8%) had an OASI complication and 842 (1.16%) underwent an OASI complication repair. Women were mainly primiparous (71.6%) and 44.3% underwent an instrumental delivery. During a follow-up of 2 years, 0.6% (n = 463), 0.3% (n = 240), 0.2% (n = 176), 0.1% (n = 84), 0.06% (n = 43) and 0.01% (n = 5) of patients underwent second surgery for a perineal repair, a fistula repair, a sphincteroplasty, a perineal infection, a colostomy and a sacral nervous anal stimulation, respectively. Only one case of artificial anal sphincter was noticed. Instrumental deliveries (OR = 1.56 CI95%[1.29;1.9]), private for-profit hospitals (OR = 1.42 [1.11;1.82], reference group "public hospital"), obesity (OR = 1.36 [1;1.84]), stage IV OASIS (OR = 2.98 [2.4;3.72]), perineal wound breakdown (OR = 2.8 [1.4;5.48]), ages between 25 and 29 years old (OR = 1.59 [1.17;2.18], refence group "age between 13 and 24 years old") and 30 and 34 years old (OR = 1.57 [1.14; 2.16], refence group "age between 13 and 24 years old") were factors associated with OASIS complication repairs. CONCLUSIONS: Maternal age, stage IV OASIS, obesity, instrumental deliveries and private for-profit hospitals seemed to predict OASIS complications. Understanding factors associated with OASIS complications could be beneficial for the patient to inform them and to influence the patient's follow-up in order to prevent complications, repairs and maternal distress.
