Recommendations of an expert group for the cardiac assessment of non-dystrophic myotonia adult patients treated with mexiletine

Mexiletine (NaMuscla™) is indicated for the symptomatic treatment of myotonia in adults with non-dystrophic myotonia. A cardiac assessment is required as mexiletine may have a pro-arrhythmic effect. Long-term safety data supporting the use of mexiletine in patients with non-dystrophic myotonia combined with the extensive clinical experience of an expert group resulted in creation of an algorithm for cardiac monitoring of patients treated with mexiletine. To define the treatment algorithm, several expert workshops including three neurologists, five cardiologists from different French neuromuscular reference centers and one pharmacologist from Italy were set up. These workshops aimed to define the screening and surveillance tools required to ensure the safe use of mexiletine in patients. The recommendations are based on the summary of product characteristics (SmPC), a review of the literature on the safety of mexiletine-treated patients with non-dystrophic myotonia, and the expertise of the authors. The expert group concluded that the cardiac safety profile of mexiletine in these patients appears to be similar to that in the general population. Therefore, patients with non-dystrophic myotonia treated with mexiletine should be monitored as per any patient with cardiac problems who are prescribed a class 1b anti-arrhythmic.

Oncologic surveillance after surgical treatment for clinically localized kidney cancer: UroCCR study n. 129.

In 2021, the EAU Guidelines implemented a novel, expert opinion-based follow-up scheme, with a three-risk-category system for clear cell (cc) and non-cc renal cell carcinoma (non-ccRCC) after surgery with curative intent. We aimed to validate the novel follow-up scheme and provide data-driven recurrence estimates according to risk groups, to confirm or implement the oncologic surveillance strategy. We identified 5,320 patients from a prospectively maintained database involving 28 French referral centers. The risk of recurrence, as either loco-regional or distant, was evaluated with the Kaplan-Meier method for each group (low- intermediate- or high-risk) according to ccRCC or non-ccRCC histology. The noncumulative distribution of recurrences was graphically investigated through the LOWESS smoother. Two thousand two hundred ninety-three (58%), 926 (23%), and 738 (19%) had low-, intermediate, and high-risk ccRCC, and 683 (50%), 297 (22%), and 383 (28%) had low-, intermediate, and high-risk non-ccRCC, respectively. Median follow-up for survivors was 46 months. Overall, 661 patients experienced recurrence. Over time, the noncumulative risk of recurrence was approximately 10% for low-risk cc-RCC, non-ccRCC, and intermediate-risk non-ccRCC, with non-significant difference among the three recurrence functions (P=0.9). At 5-year, time point after which imaging should be de-intensified to biennial, the noncumulative risks of recurrence were: for intermediate risk ccRCC and non-ccRCC: 15% and 11%, respectively; for high-risk ccRCC and non-ccRCC: 24% and 8%, respectively. Among high-risk non-ccRCC patients there were 9 recurrences at 3-month. There was no significant difference between the recurrence function of high-risk non-ccRCC patients with negative imaging at 3-month and the one of intermediate-risk ccRCC (P=0.3). Given the relatively low recurrence risk of patients with intermediate-risk non-ccRCC, those individuals could be followed up with a similar strategy to the low-risk category. Similarly, patients with high-risk non-ccRCC with negative imaging at 3-month, could be followed up similarly to intermediate-risk ccRCC after the 3-month time point.

Predictors of substance use during treatment for addiction: A network analysis of ecological momentary assessment data.

Ecological momentary assessment (EMA) studies have previously demonstrated a prospective influence of craving on substance use in the following hours. Conceptualizing substance use as a dynamic system of causal elements could provide valuable insights into the interaction of craving with other symptoms in the process of relapse. The aim of this study was to improve the understanding of these daily life dynamic inter-relationships by applying dynamic networks analyses to EMA data sets. Secondary analyses were conducted on time-series data from two 2-week EMA studies. Data were collected in French outpatient addiction treatment centres. A total of 211 outpatients beginning treatment for alcohol, tobacco, cannabis, stimulants and opiate addiction took part. Using mobile technologies, participants were questioned four times per day relative to substance use, craving, exposure to cues, mood, self-efficacy and pharmacological addiction treatment use. Multi-level vector auto-regression models were used to explore contemporaneous, temporal and between-subjects networks. Among the 8260 daily evaluations, the temporal network model, which depicts the lagged associations of symptoms within participants, demonstrated a unidirectional association between craving intensity at one time (T0) and primary substance use at the next assessment (T1, r = 0.1), after controlling for the effect of all other variables. A greater self-efficacy at T0 was associated with fewer cues (r = -0.04), less craving (r = -0.1) and less substance use at T1 (r = -0.07), and craving presented a negative feedback loop with self-efficacy (r = -0.09). Dynamic network analyses showed that, among outpatients beginning treatment for addiction, high craving, together with low self-efficacy, appear to predict substance use more strongly than low mood or high exposure to cues.

Practice survey on recent changes in post cardiac arrest care and temperature management in French intensive care units

BackgroundRecent guidelines for post-cardiac arrest (CA) management have undergone significant changes regarding targeted therapeutic management (TTM), transitioning from hypothermia to temperature control. We aimed to assess changes in post-CA management in French intensive care units following the new recommendations. MethodsTwo declarative web surveys were conducted from March to August 2023. We compared the doctors' survey to that previously published in 2015. We contacted 389 departments from 276 French centers. ResultsThree hundred thirty-four physicians from 189 distinct ICUs departments participated in the survey. TTM was used by 95.5 % of respondents. TTM with temperature feedback device was used by 64 % of respondents. In multivariate analysis, use of TTM with temperature feedback was associated with university hospital responder [OR 1.99 (1.19–3.34, p = 0.009)], high CA admissions rate [OR 2.25 (1.13–4.78, p = 0.026)], use of a written CA procedure [OR 1.76 (1.07–2.92, p = 0.027)] and presence of a cath-lab performing coronary angiography [OR 2.42 (1.33–4.44, p = 0.004)]. The targeted temperature rose from 32 to 34 °C in 2015, to 35–36 °C in 2023 (p < 0.001). Proportions of TTM with temperature feedback devices switched from 45 % to 65 % (p < 0.001). 660 nurses responses from 150 ICUs were analyzed. According to TTM users, gel-coated water circulating pads and intravascular cooling were considered the most effective devices and were found to be easily adjustable. ConclusionsThese surveys provide insights into post-resuscitation care and TTM practice in France. One year after their publication, the latest recommendations concerning TTM have not been fully implemented, as the majority of ICUs continue to use moderate hypothermia. They widely reported employing specific TTM, with the use of TTM with temperature feedback devices increasing significantly. Heterogeneity exists regarding the TTM systems used, with a significant proportion lacking temperature feedback. This aspect requires specific attention, depending on local constraints and devices costs.

Characterization of Digestive Manifestations in Patients with Impaired PTH/PTHrP Signaling Disorder/Pseudohypoparathyroidism.

Pseudohypoparathyroidism, newly classified as inactivating PTH/PTHrP signaling disorder (iPPSD) type 2 or type 3, is a rare disease caused by defects in the GNAS imprinted gene that encodes Gsα. The most common phenotype comprises resistance to hormones binding to G protein-coupled receptors such as PTH, PTHrP, or TSH, subcutaneous ossifications, short stature, brachydactyly, and early onset obesity. Uncommon features have been described including sleep apnea, asthma, and resistance to calcitonin. At the national French reference center for rare calcium and phosphate metabolism diseases, a large cohort of patients with iPPSD type 2 and type 3 is followed. Interestingly, digestive manifestations and in particular intractable constipation were regularly reported by families of children with iPPSD type 2 or type 3. The aim of our study was therefore to specify the frequency and characteristics of digestive manifestations in children followed up for iPPSD2 or iPPSD3 in our reference center. Thirty-six patients aged between 2 and 18 years (32 followed up for iPPSD2 and 4 for iPPSD3) were included. Parents completed a specific questionnaire to assess any digestive disorders in their child. The diagnosis of constipation was established using the Bristol visual scale in the event of a score of less than 2 according to stool appearance. Parents reported constipation through the questionnaires in 22/36 (over 60%) of the children. It was the most frequently reported digestive disorder. Among these 22 children, 19 (87%) had a Bristol score for stool shape and texture between 1 and 2 on a scale of 7, confirming constipation. Dedicated treatment had been initiated for 10 (55%) of them, yet only 3 families (16%) considered this treatment effective. Neonatal vomiting and eating disorders, such as lack of satiety or food selectivity, were also noted in 18 (50%) of patients, as was gastroesophageal reflux present in the neonatal period in 14 (40%) of children. There were no significant differences according to the type of iPPSD or patient age. Our work shows for the first time that digestive manifestations, including constipation, occur frequently in children followed for iPPSD, suggesting a potential role of Gsα and G protein receptors in the digestive tract. It is well known that constipation and digestive symptoms alter quality of life. Early management is therefore essential to improve the quality of life of children followed for iPPSD. Our data need to be confirmed on a larger cohort.

BackgroundThe rate of thromboembolic events (TEEs) associated with endovascular treatment (EVT) of intracranial aneurysms is not reported uniformly in the literature due to the various ways that are used to...

Severe Intraocular Inflammation After Intravitreal Injection of Faricimab: A Single-Site Case Series of Six Patients

To describe the patient characteristics and clinical course of severe intraocular inflammation (IOI) following intravitreal injection (IVT) of faricimab. Retrospective case series. Case series at a single French academic center (Dijon University Hospital) where 263 patients were treated with faricimab IVT between January 9, 2024 and May 7, 2024. Over the 4-month period, a total of 1659 eyes (1338 patients) received anti-vascular endothelial growth factor (anti-VEGF) IVTs for a total of 3510 IVTs, of which 343 eyes (263 patients) received faricimab IVTs for a total of 971 IVTs. Overall, 6 pretreated eyes with neovascular age-related macular degeneration that were switched to faricimab developed severe unilateral IOI following faricimab IVT (1/162 injections [0.62%]), including 5 eyes presenting with a severe anterior and intermediate uveitis mimicking infectious endophthalmitis. All eyes were normotensive and presented with mild to moderate pain and predominantly moderate vitritis, associated with granulomatous keratic precipitates in 2 eyes and nonocclusive vasculitis in one eye. The clinical presentation, sterile vitreous sample culture, and rapid improvement with treatment made the diagnosis of infectious endophthalmitis unlikely. Four patients out of 6 did not recover their pre-IOI visual acuity, with an average visual loss of +0.2 logMAR. Two patients had positive antinuclear antibodies, including one with a history of cutaneous lupus. In this case series, we reported 6 cases of severe IOI after intravitreal faricimab over 4 months in a single French center with an estimated incidence rate of 0.6% per injection. Future real-world data will contribute to a better evaluation of the epidemiology of this rare inflammatory adverse event related to intravitreal faricimab.

Characteristics of large granular lymphocyte leukemia associated with variable common immunodeficiency disorders: A study of 12 cases.

Common Variable Immunodeficiency Disorders (CVID) and Large Granular Lymphocytes leukemia (LGLL) exhibit diverse clinical manifestations including infections, dysimmunity, and lymphoproliferation. Recent decades have seen the discovery of new genes in the lymphopoiesis pathway, such as JAK-STAT. This case series supplemented by a literature review aims to describe clinical and biological characteristics of patients with both CIVD and LGLL. Patients were included through a call for comments to French and Belgian centers and through a literature review via PubMed. Clinical characteristics were compared to two large French cohort involving CVID and LGLL patients. Twelve patients were included. In all cases, CVID precedes LLGL (median diagnosis delay for LLGL was 7 years). Most cases presented with splenomegaly and autoimmune cytopenia. Ten out of 12 patients underwent splenectomy during follow up. Patients with LGLL and CVID differ from patients without immune deficiency in term of clinical presentation and prognosis. We suggest CVID may act as a trigger of LGL lymphocytosis, due to endogenous and exogenous antigenic pressure leading to the selection of a dominant LGL clone and stimulation of the JAK-STAT pathway. The role of splenomegaly and splenectomy in LGLL onset warrant further investigation in future studies.

Corneal Toxicity in Patients Treated by BELANTAMAB MAFODOTIN: How to Improve and Facilitate Patients Follow-Up Using Refractive Shift?

Purpose: Multiple myeloma (MM) is the second most common neoplastic blood disease worldwide. Belantamab mafodotin is a new antibody conjugate anti-B-cell maturation antigen effective against refractory myelomas. It induces intracorneal microcysts leading to refractive fluctuations. The aim of this study is to assess the value of monitoring refractive fluctuations based on the location of microcystic-like epithelial changes (MECs) to facilitate patient follow-up. Methods: This observational and multicentric study was conducted using data collected from several French centers contacted through secure email through a standardized data collection table. Results: The fluctuation of objective refraction in spherical equivalent confirms a significant myopic shift from peripheral to central forms. A decrease in the best-corrected visual acuity (BCVA), an increase in keratometry, and an increase in central epithelial pachymetry have also been observed when MECs migrate toward the center. Conclusion: The myopization found in our study in patients with central and paracentral MECs is consistent with current literature. Fluctuations in BCVA, keratometry, and epithelial pachymetry are also consistent. This study is the first real-world study and highlights heterogeneity in follow-up, emphasizing the need to establish multidisciplinary follow-up strategies. The analysis of refractive fluctuations appears to be a reproducible and noninvasive screening method that could facilitate patient follow-up without the need for consultation focused on corneal diseases.

French validation of the oMtFSFI Questionnaire for assessing the sexual function of Transgender women after vulvo-vaginoplasty

IntroductionThe Operated Male-to-Female Sexual Function Index (oMtFSFI) questionnaire is the first scoring system developed to assess sexual function after gender-affirming vulvo-vaginoplasty, and was initially developed and validated in Italian. The aim of this study was to provide linguistic validation of the questionnaire in French through several steps including use of the questionnaires across a series of patients who had undergone gender-affirming vulvo-vaginoplasty between 2020 and 2022 at two French academic centers. MethodThe French version of the oMtFSFI questionnaire was obtained through a double translation (Italian to French) and a back-translation (French to Italian), validated by a scientific committee, and cognitively assessed by a panel of expert patients. The questionnaire was then distributed to transgender male to female patients who had undergone genital gender affirming surgery at two French academic centers. ResultsThe oMtFSFI score consists of 18 questions exploring 7 domains (genital self-image, desire, arousal, lubrication, orgasm, satisfaction, sexual pain). Among the sixty-four patients who responded to the questionnaire, 16 patients (25%) reported abstaining from sexual activity involving vaginal penetration at the time of the study were excluded. The mean total score was 37, corresponding to mild to moderate sexual dysfunction and 60.4% of the patients reported normal overall sexual function. The level of sexual satisfaction was normal for 68.8% of the patients and the genital self-image was normal for 52.1%. Most of the patients (79.2%) reported at least mild dyspareunia and 10.4% had critical sexual dysfunction. Surgery improved gender dysphoria in 96.7% of patients. There was a strong correlation between the overall oMtFSFI score and the happiness Visual Analog Scale (VAS) (P<0.001) as well as with the quality of life VAS (P<0.001). ConclusionThe French version of the oMtFSFI questionnaire is the only scoring system specifically developed to assess sexual function after vulvo-vaginoplasty in transgender women linguistically validated in French. Its validation in French language makes it an interesting tool for research and clinical practice. Level of evidence3.

O-250 Never a lost cause: can artificial intelligence (AI)-powered ranking help decrease time to pregnancy when only poor-quality embryos are available?

Abstract Study question Can an objectively trained AI system complement embryologists in their ranking of embryos and minimize time to pregnancy, when only poor-quality embryos are available? Summary answer An objective AI algorithm could have decreased cycle to pregnancy by 18% in cohorts of embryos where only poor-quality embryos were available. What is known already Morphokinetics is a key criterion for embryologists to rank embryos as good, fair, or poor quality, with the latter frequently being discarded. Although poor-quality embryos can still lead to a pregnancy, selection of a viable embryo remains challenging to embryologists due to their depleted morphological characteristics. Unlike embryologists, an AI can be trained to see beyond embryo morphological quality, on data that includes many poor-quality embryos that resulted in a pregnancy. As such, AI has the potential to recognize viable poor-quality embryos, which becomes especially crucial in cases where good or fair embryos are unavailable from the embryo pool. Study design, size, duration Data from a French center was acquired through a MIRI® (ESCO) time-lapse system and uploaded on EMBRYOLY, between January 2022 and March 2023. For a total of 204 patients (women’s average age 35 y.o.), embryologists were faced with having to choose an embryo to transfer among 4.3 ± 1.7 poor-quality embryos either because the cohort was composed of only poor-quality embryos or because higher quality embryos had already been transferred. Participants/materials, setting, methods A previously described deep learning algorithm trained on videos of developing embryos with known pregnancy outcome was used to score embryos according to their chances of leading to a clinical pregnancy (fetal heartbeat between 6-9 weeks). A 2D ResNet model was trained, validated and tested on 8138 images of day 5 embryos annotated by senior embryologists to identify those of poor-quality (Gardner grade ICM and/or TE = C, corresponding to 44.7% of the dataset). Main results and the role of chance The association between video predictions and pregnancy was assessed with a logistic regression. A McNemar test was used to compare cycle to pregnancy (CTP) with and without EMBRYOLY’s hypothetical impact. EMBRYOLY’s AI was able to rank poor-quality embryos, as illustrated by a 2-7% relative increase in likelihood of clinical pregnancy observed with an increase in the video score (logistic regression with unit level +0.02, OR = 1.04, 95CI = [1.02-1.07], N = 261 transferred embryos, p &amp;lt; 0.05). EMBRYOLY’s first choice was concordant with the embryologists’ first choice in 74% of the cases that led to a pregnancy (N = 42 embryos). For patients who had two poor-quality embryos transferred with at least one pregnancy (N = 14 cycles), the results show that if the embryologist had first transferred the highest EMBRYOLY-ranked embryo, the number of cycles to pregnancy would have been reduced by 18% (from 1.7 to 1.4, McNemar, p &amp;lt; 0.05), corresponding to a median of 2.3 months. Limitations, reasons for caution The endpoint used was clinical pregnancy as measured by fetal heartbeat, and does not indicate the probability of live birth. The current investigation was performed with retrospective data from a single center. In the future, a multi-centre evaluation should be performed to generalize our findings. Wider implications of the findings Our findings support that an objectively trained AI can help embryologists not miss out on poor-quality embryos that can lead to a pregnancy, which is all the more important to target when good or fair embryos are unavailable from the embryo pool.

Shift in emergency department utilization by frequent attendees with sickle cell disease during the COVID-19 pandemic: Amulticentre cohort study.

While the coronavirus disease-2019 (COVID-19) might have increased acute episodes in people living with sickle cell disease (SCD), it may also have changed their reliance on emergency department (ED) services. We assessed the impact of the COVID-19 pandemic and lockdowns on ED visits in adult SCD people followed in five French reference centres, with a special focus on 'high users' (≥10 visits in 2019). We analysed the rate of ED visits from 1 January 2015 to 31 December 2021, using a self-controlled case series. Among 1530 people (17 829 ED visits), we observed a significant reduction in ED visits during and after lockdowns, but the effect vanished over time. Compared to pre-pandemic, incidence rate ratios for ED visits were 0.59 [95% CI 0.52-0.67] for the first lockdown, 0.66 [95% CI 0.58-0.75] for the second and 0.85 [95% CI 0.73-0.99] for the third. High users (4% of people but 33.7% of visits) mainly drove the reductions after the first lockdown. COVID-19 lockdowns were associated with reduced ED visits. While most people returned to their baseline utilization by April 2021, high users had a lasting decrease in ED visits. Understanding the factors driving the drop in ED utilization among high users might inform clinical practice and health policy.

P-722 What is the state of well-being among professionals working in French Assisted Reproductive Technology (ART) centers?

Abstract Study question What is the state of well-being among professionals working in French Assisted Reproductive Technology (ART) centers? Summary answer Over 35% of French ART professionals experience job strain, and an additional 21% lack social support, posing risks of stress, burnout, and physical health issues. What is known already The health of professionals is notably impacted by the psychosocial work environment, where stress arises from imbalances between demands and available resources. Job strain, characterized by high psychological demands and low decision latitude, can lead to negative health outcomes, especially when combined with poor social support. Research on the well-being of diverse ART teams is scarce. Previous studies focused on burnout risk among embryologists in the US, Spain, and the UK, leaving other professional categories unexplored. A wider understanding of the psychosocial dynamics within ART centers is crucial for promoting a supportive work environment and limiting stress-related challenges among professionals. Study design, size, duration This cross-sectional study aims at evaluating the state of well-being among professionals working in the 104 French ART centers. An online survey was distributed via email to potential participants from November 2023 to January 2024. The questionnaire was built upon Karasek and Siegrist’s models. It included 26 queries assessing psychological demands, decision latitude, and social support, along with 23 questions evaluating effort, rewards, and perceived control. Additional questions covered personal and professional details. Participants/materials, setting, methods Responses were scored based on predefined points for psychological demand, decision latitude, job support, extrinsic efforts, and rewards. According to Karasek model, job strain combines high psychological demands (score &amp;gt;21) with low decision latitude (score &amp;lt;70). Isostrain, a more severe form of job strain, adds low social support (score &amp;lt;24) to job strain. Siegrist’s model identifies work situations with an imbalance between extrinsic efforts and rewards (ratio effort/reward &amp;gt;1). Main results and the role of chance The study included 464 participants (13% participation rate), including biologists (n = 129, 28%), gynecologists (n = 125, 27%), embryologists (n = 106, 23%), secretaries (n = 51, 11%), midwifes (n = 31, 6%) and other professions (n = 22, 5%). Most professionals were women (81.5%), while the remaining where men (18.1%) mainly biologists and gynecologists, and non-binary individuals (0.4%). Among all professionals, 164 (36%) experience job strain, while others either fell in active (n = 186, 40%), relaxed (n = 68, 15%) or passive (n = 41, 9%) categories. Furthermore, 80 (21%) professionals were in an isostrain situation. A total of 15% of professionals experience an imbalance between their extrinsic efforts and rewards. Multivariate analysis showed that women (OR 2.10 [1.07; 4.11]), public centers (OR 1.86 [1.13; 3.08]), embryologists (OR 9.26 [4.90; 17.50]), and secretaries (OR 5.78 [2.75; 12.17]) exhibited higher job strain risks compared to men, for-profit private centers, and gynecologists. Gender and function also showed significant associations with isostrain risk. Moreover, working 10 hours per day for 5-6 days weekly (OR 4.75 [1.47; 15.37]), along with functions of embryologists (OR 7.58 [2.21; 26.05]) and secretaries (OR 4.41 [1.20; 16.18]), were independently associated with an effort/reward imbalance, compared to a 4-day weekly work schedule and the function of gynecologist, respectively. Limitations, reasons for caution Due to the email distribution method, some professionals might not have received the survey. Sampling or non-response bias may result in the underrepresentation of specific individuals, limiting the generalizability of the findings. Finally, used scales might not fully capture all psycho-emotional aspects, such as burnout levels or quality of life. Wider implications of the findings 35% of French ART professionals face psychosocial imbalance, exceeding the general population’s rate (23.2%, Sumer study, 2003). Job strain may affect care quality (Scheepers et al., 2015), so research is needed to understand its causes and potential impact. Organizational and managerial improvements could constitute preventive approaches to stress and burnout. Trial registration number Not applicable

O-011 Is there a need for LH surge inhibition by GnRH-antagonists in luteal phase stimulation in poor ovarian responders undergoing Duostim? Efficacy of natural progesterone

Abstract Study question Is there a need for LH surge inhibition by GnRH-antagonists in luteal phase stimulation in poor ovarian responders undergoing Duostim? Summary answer Inhibition of the LH surge by progesterone during the luteal phase of duostim protocols in POR appears to be effective, safe and makes GnRH-antagonists unnecessary. What is known already High levels of progesterone have long been shown to reversibly block the LH surge associated with increased estradiol levels, by reducing GnRH’s pulsatility from the hypothalamus. This inhibition is the basis of progestin-only contraceptives and has been shown to be completely reversible by discontinuing the progestin, and even seems to have a potentiating effect on the surge which occurs in the subsequent few days Study design, size, duration This is a secondary analysis of the BISTIM study, a multicentre, open-labelled randomized controlled trial, performed in 4 french IVF centers from 2018 to 2021, designed to compare Duostim protocol versus two follicular stimulations. We here present a paired-controlled study including patients randomized in the Duostim group, who underwent 2 consecutive stimulations in the same menstrual cycle, we compare the follicular phase stimulation with GnRH-antagonist versus the luteal phase stimulation with progesterone. Participants/materials, setting, methods The BISTIM study recruited poor ovarian reserve women defined with Bologna criteria who enrolled in an IVF or ICSI program, aged from 20 to 41, with BMI from 19 to 32, with no more than 2 previous IVF cycles. Women with amenorrhea, FSH &amp;gt;20 UI/L or CFA &amp;lt;1 were not included. 32 of them underwent two stimulations, consecutively. Main results and the role of chance For the same group of 32 women, stimulation parameters were similar between 1st and 2nd stimulations (stimulation duration, gonadotropin doses, number of retrieved oocytes). As expected, progesterone levels were significantly higher at D5 in the study group compared to controls (mean 34.8 ng/ml, Q1-Q3 [18.4 – 51.6])) and were still significantly higher at HCG-day (10.7 ng/ml, Q1-Q3 [2.7 – 14.3])), despite the addition of natural exogenous progesterone. LH levels were significantly lower in the progesterone group, regardless of the day of stimulation: at HCG day mean LH was 1,7 UI/L in the study group versus 6.8 UI/L in the control group, p &amp;lt; 0.001. In the Duostim group no premature LH surge/ovulation was observed, however, 2 cancellations for premature ovulation were reported with antagonist protocol in the control group of the BISTIM study. Limitations, reasons for caution This study was carried out on a limited number of subjects (n = 32), all of whom were poor responders. Wider implications of the findings This study shows the effectiveness of LH surge inhibition by progestins, which represent a less expensive and more patient-friendly treatment than traditional protocols. Further studies are needed to determine the best protocol (type and doses of progestins) to effectively inhibit the LH surge, and on larger and different cohorts. Trial registration number 2017-A00498-45

Hip and knee arthroplasty in one surgical session: early morbi-mortality study

IntroductionBilateral prosthetic hip or knee replacement in one surgical session is a procedure that has been widely validated in the literature, whereas hip and knee replacement in one surgical session remains poorly documented. This study reports on the results of these procedures by analyzing early post-operative complications in a retrospective multicenter study. Material and methodsBetween 2009 and 2023, 51 patients underwent hip and knee replacement surgery in a single surgical session at 4 French centers. They were 24 men and 27 women, with a mean age of 68.8 years (36–87); 7 patients were ASA 1, 30 were ASA 2 and 14 ASA 3. Prosthetic hip replacement was always performed first, associated 33 times with the ipsi-lateral knee and 18 times with the contralateral knee. All early complications, within the first 90 days post-operatively, were recorded: death, phlebitis, pulmonary embolism, myocardial infarction, surgical site infection (SSI), knee stiffness treated by mobilization under general anesthesia, urinary tract infection, acute urine retention or any other adverse event related to care. Transfusion rates were also reported. ResultsThe rate of early complications was 9.8% (5/51). No deaths, no phlebitis, no pulmonary embolism and no SSI were observed. Complications included one myocardial infarction, one urinary tract infection, one superficial infection, one haematoma treated by surgical evacuation and one recurrent instability requiring revision surgery (hip arthroplasty). The transfusion rate was 17.6% (9/51). The complication rate of ASA 3 patients was higher than that of ASA 1 and 2 patients, while there was no difference related to age or BMI. DiscussionOur results confirm the feasibility of single-stage hip and knee replacement, with a low complication rate in ASA 1 and 2 patients. This study adds to the few published works on the subject and reports comparable results. The small sample size and the heterogeneity of patients and centers limit the scope of the results, these limitations being relative to the volume expected for a rare procedure. ConclusionSingle-session hip and knee arthroplasty should be reserved for patients selected according to comorbidities: ASA score, age and body mass index. ASA 3 patients have a higher risk of complications. Level of evidenceIV; retrospective

EUS-guided hepaticojejunostomy in patients with history of total gastrectomy: a multicenter retrospective feasibility study (with video)

EUS-guided hepaticogastrostomy (EUS-HGS) is an effective biliary drainage technique for patients with altered anatomy or duodenal strictures. EUS-guided hepaticojejunostomy (EUS-HJS) can be used to create a fistula between the left hepatic duct and the jejunum in patients with a history of total gastrectomy. No specific data on this technique have been published. The aim of this study was to assess the feasibility and safety of EUS-HJS in patients with a history of total gastrectomy. This retrospective multicenter study included all adult patients who underwent EUS-HJS at 3 tertiary French centers and 1 tertiary Swiss center between May 2011 and February 2023. The primary outcome was clinical success, which was defined as the disappearance of pruritus, jaundice, and/or cholangitis. An improvement in bilirubin >30% within the first week and/or bilirubin normalization within 1 month after the procedure were also considered indicators of clinical success. Secondary outcomes were technical success, rate of adverse events, need for endoscopic revision, possibility of resuming anticancer treatment, median survival, and technical differences compared with EUS-HGS. Twenty-one patients with history of complete gastrectomy who underwent EUS-HJS were included. Technical success was achieved in 100% of patients (95% confidence interval [CI], 85-100). Clinical success was achieved in 80% of patients (95% CI, 58-92). The incidence of recorded adverse events was 33% (95% CI, 17-55), with cholangitis being the most frequent adverse event. Seven patients (39%) were able to benefit from anticancertreatment after the procedure. Median survival time was 6 months (interquartile range, 1.5-12). EUS-HJS is an effective and feasible procedure for patients whose anatomy has been altered by total gastrectomy.

Risk Factors for Artificial Urinary Sphincter Explantation and Erosion in Male Nonneurological Patients.

This study was performed to assess the risk factors for artificial urinary sphincter (AUS) explantation in a large multicenter cohort. We retrospectively reviewed the medical records for all 1,233 implantations of the AMS-800 AUS device in male nonneurological patients from 2005 to 2020 across 13 French centers. Patients with neurological conditions were excluded from the study. To identify factors associated with explantation-free survival, survival analysis was performed. Explantation was defined as the complete removal of the device, whereas revision referred to the replacement of the device or its components. The study included 1,107 patients, of whom 281 underwent AUS explantation. The median survival without explantation was 83 months. The leading causes of explantation were infection and erosion. Univariate analysis revealed several significant risk factors for explantation: age above 75 years (34.6% in the explanted group vs. 25.8% in the nonexplanted group, P=0.007), history of radiotherapy (43.5% vs. 31.3%, P=0.001), and anticoagulant use (15% vs. 8.6%, P<0.001). In logistic regression analysis, the only significant risk factor was previous radiotherapy (odds ratio [OR], 2.05; P<0.05). Cox proportional hazards analysis revealed 2 factors associated with earlier explantation: transcorporal cuff implantation (hazard ratio [HR], 2.67; P=0.01) and the annual caseload of the center (HR, 1.08; P=0.02). When specifically examining explantation due to erosion, radiotherapy was the sole factor significantly associated with the risk of erosion (OR, 2.47; P<0.05) as well as earlier erosion (HR, 1.90; P=0.039). In this series, conducted in a real-world setting across multiple centers with different volumes and levels of expertise, the median survival without AUS explantation was 83 months. This study confirms that radiotherapy represents the primary independent risk factor for AUS erosion in male nonneurological patients.

Preoperative brachytherapy of early-stage cervical cancer: A multicenter study by the SFRO brachytherapy group

ObjectiveTo report the results of a multicenter cohort of preoperative brachytherapy (PBT) for treatment of early-stage cervical cancer (ESCC). MethodsA retrospective analysis was conducted among five French comprehensive cancer centers on behalf of the SFRO Brachytherapy Group to examine the outcome of patients with ESCC who received PBT between 2001 and 2019 because of adverse prognostic factors (tumor size >2 cm, presence of lymphovascular invasion, adenocarcinoma).Brachytherapy was followed 4–8 weeks later by surgery. Local relapse free, distant metastasis-free survival, disease-free, and overall survival and adverse effects were examined. Uni- and multivariate analyses were conducted looking for oncological prognostic factors. ResultsA total of 451 patients were identified, with a mean tumor size of 24.7 mm. Adenocarcinoma accounted for 43.5% of cases, and lympho-vascular space invasion (LVSI) was present in 15.7%. A complete histological response was observed in 69.6%. With a mean follow-up of 75.4 months, DFS, LRFS, and OS rates at five years were 88% [95% CI (84–91), 98% [95% CI (96–99), and 92% [95% CI (87–95)], respectively. At the last follow-up, 8.2% of patients had died, including 31 (6.8%) from cervical cancer. Severe side effects range from 1.1% to 2%. At multivariate analysis, adenocarcinoma histological type, tumor size ≥2 cm, and the presence of residual tumors were prognosticators for DFS and DMFS. ConclusionPBT shows excellent oncological outcomes in this cohort of patients with adverse histoprognostic factors. Favorable survival rates and low complications rates were observed, supporting this strategy in the management of ESCC.

One-Year Mortality After Lung Transplantation: Experience of a Single French Center Between 2012 and 2021.

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.
