Comparison of rescue intracranial stenting versus best medical treatment alone in acute refractory large vessel occlusion: study protocol for the PISTAR multicenter randomized trial.

BACKGROUND: Mechanical thrombectomy (MT) has become a standard treatment for acute ischemic strokes (AIS). However, MT failure occurs in approximately 10-30% of cases, leading to severe repercussions (with mortality rates up to 40% according to observational data). Among the available rescue techniques, rescue intracranial stenting (RIS) appears as a promising option. OBJECTIVE: This trial is poised to demonstrate the superiority of RIS in addition to the best medical treatment (BMT) in comparison with BMT alone, in improving the functional outcomes at 3 months for patients experiencing an AIS due to a large vessel occlusion refractory to MT (rLVO). METHODS: Permanent Intracranial STenting for Acute Refractory large vessel occlusions (PISTAR) is a multicenter prospective randomized open, blinded endpoint trial conducted across 11 French University hospitals. Adult patients (≥18 years) with an acute intracranial occlusion refractory to standard MT techniques will be randomized 1:1 during the procedure to receive either RIS+BMT (intervention arm) or BMT alone (control arm). RESULTS: The primary outcome is the rate of good clinical outcome at 3 months defined as a modified Rankin Scale score ≤2 and evaluated by an independent assessor blinded to the randomization arm. Secondary outcomes include hemorrhagic complications, all adverse events, and death. The number of patients to be included is 346. Two interim analyses are planned with predefined stopping rules. CONCLUSION: The PISTAR trial is the first randomized controlled trial focusing on the benefit of RIS in rLVOs. If positive, this study will open new insights into the management of AIS.

Interim FDG-PET improves treatment failure prediction in primary central nervous system Lymphoma: a LOC network prospective multicentric study.

PURPOSE: The purpose of our study was to assess the predictive and prognostic role of 2-18F-fluoro-2-deoxy-D-glucose (FDG) PET/MRI during high-dose methotrexate-based chemotherapy (HD-MBC) in de novo primary central nervous system lymphoma (PCNSL) patients aged 60 and above. METHODS: This prospective multicentric ancillary study included 65 immunocompetents patients who received induction HD-MBC as part of the BLOCAGE01 phase III trial. FDG-PET/MRI were acquired at baseline, post two cycles (PET/MRI2), and post-treatment (PET/MRI3). FDG-PET response was dichotomized, with "positive" indicating persistent tumor uptake higher than the contralateral mirroring brain region. Performances of FDG-PET and International PCNSL Collaborative Group criteria in predicting induction response, progression-free survival (PFS), and overall survival (OS) were compared. RESULTS: Of 48 PET2 scans performed, nine were positive and aligned with a partial response (PR) on MRI2. Among these, eight (89%) progressed by the end of the induction phase. In contrast, 35/39 (90%) of PET2-negative patients achieved complete response (CR). Among the 18 discordant responses at interim (PETCR/MRIPR), 83% ultimately achieved CR. 87% of the PET2-negative patients were disease-free at 6 months versus 11% of the PET2-positive patients (p<0.001). The MRI2 response did not significantly differentiate patients based on their PFS, regardless of whether they were in CR or PR. Both PET2 and MRI2 independently predicted OS in multivariate analysis, with PET2 showing stronger association. CONCLUSION: Our study highlights the potential of interim FDG-PET for early management of PCNSL patients. Response-driven treatment based on PET2 may guide future clinical trials.

Embolization of the middle meningeal artery for the prevention of chronic subdural hematoma recurrence in high-risk patients: a randomized controlled trial-the EMPROTECT study protocol.

BACKGROUND: Middle meningeal artery (MMA) embolization has been proposed as a treatment of chronic subdural hematoma (CSDH). The benefit of the procedure has yet to be demonstrated in a randomized controlled trial. We aim to assess the efficacy of MMA embolization in reducing the risk of CSDH recurrence 6 months after burr-hole surgery compared with standard medical treatment in patients at high risk of postoperative recurrence. METHODS: The EMPROTECT trial is a multicenter open label randomized controlled trial (RCT) involving 12 French centers. Adult patients (≥18 years) operated for CSDH recurrence or for a first episode with a predefined recurrence risk factor are randomized 1:1 to receive either MMA embolization within 7 days of the burr-hole surgery (experimental group) or standard medical care (control group). The number of patients to be included is 342. RESULTS: The primary outcome is the rate of CSDH recurrence at 6 months. Secondary outcomes include the rate of repeated surgery for a homolateral CSDH recurrence during the 6-month follow-up period, the rate of disability and dependency at 1 and 6 months, defined by a modified Rankin Scale (mRS) score ≥4, mortality at 1 and 6 months, total cumulative duration of hospital stay during the 6-month follow-up period, directly or indirectly related to the CSDH and embolization procedure-related complication rates. CONCLUSIONS: The EMPROTECT trial is the first RCT evaluating the benefit of MMA embolization as a surgical adjunct for the prevention of CSDH recurrence. If positive, this trial will have a significant impact on patient care. TRIAL REGISTRATION NUMBER: NCT04372147.

Evaluation of mechanical thrombectomy in acute ischemic stroke related to a distal arterial occlusion: A randomized controlled trial.

RATIONALE: Mechanical thrombectomy (MT) associated with the best medical treatment (BMT) has recently shown efficacy for the management of acute ischemic stroke (AIS) secondary to a large vessel occlusion. However, evidence is lacking regarding the benefit of MT for more distal occlusions. AIM: To evaluate the efficacy in terms of good clinical outcome at 3 months of MT associated with the BMT over the BMT alone in AIS related to a distal occlusion. METHODS: The DISCOUNT trial is a multicenter open-label randomized controlled trial involving French University hospitals. Adult patients (⩾18 years) with an AIS involving the anterior or posterior circulation secondary to a distal vessel occlusion within 6 h of symptom onset or within 24 h if no hyperintense signal on fluid attenuation inversion recovery acquisition will be randomized 1:1 to receive either MT associated with the BMT (experimental group) or BMT alone (control group). The number of patients to be included is 488. STUDY OUTCOMES: The primary outcome is the rate of good clinical outcome at 3 months defined as a modified Rankin scale (mRS) ⩽2 and evaluated by an independent assessor blinded to the intervention arm. Secondary outcomes include recanalization of the occluded vessel within 48 h, angiographic reperfusion in the experimental group, 3-month excellent clinical outcome (mRS ⩽ 1), all adverse events, and death. A cost utility analysis will estimate the incremental cost per quality-adjusted life year (QALY) gained. DISCUSSION: If positive, this study will open new insights in the management of AISs. TRIAL REGISTRATION: ClinicalTrials.gov: NCT05030142 registered on 1 September 2021.

[18F]FDG PET-MRI provides survival biomarkers in primary central nervous system lymphoma in the elderly: an ancillary study from the BLOCAGE trial of the LOC network.

PURPOSE: Primary central nervous system lymphoma (PCNSL) incidence is rising among elderly patients, presenting challenges due to poor prognosis and treatment-related toxicity risks. This study explores the potential of combining [18F]fluorodeoxyglucose ([18F]FDG) PET scans and multimodal MRI for improving management in elderly patients with de novo PCNSL. METHODS: Immunocompetent patients over 60 years with de novo PCNSL were prospectively enrolled in a multicentric study between January 2016 and April 2021. Patients underwent brain [18F]FDG PET-MRI before receiving high-dose methotrexate-based chemotherapy. Relationships between extracted PET (metabolic tumor volume (MTV), sum of MTV for up to five lesions (sumMTV), metabolic imaging lymphoma aggressiveness score (MILAS)) and MRI parameters (tumor contrast-enhancement size, cerebral blood volume (CBV), cerebral blood flow (CBF), apparent diffusion coefficient (ADC)) and treatment response and outcomes were analyzed. RESULTS: Of 54 newly diagnosed diffuse large B-cell PCNSL patients, 52 had positive PET and MRI with highly [18F]FDG-avid and contrast-enhanced disease (SUVmax: 27.7 [22.8-36]). High [18F]FDG uptake and metabolic volume were significantly associated with low ADCmean values and high CBF at baseline. Among patients, 69% achieved an objective response at the end of induction therapy, while 17 were progressive. Higher cerebellar SUVmean and lower sumMTV at diagnosis were significant predictors of complete response: 6.4 [5.7-7.7] vs 5.4 [4.5-6.6] (p = 0.04) and 5.5 [2.1-13.3] vs 15.9 [4.2-19.5] (p = 0.01), respectively. Two-year overall survival (OS) was 71%, with a median progression-free survival (PFS) of 29.6 months and a median follow-up of 37 months. Larger tumor volumes on PET or enhanced T1-weighted MRI were significant predictors of poorer OS, while a high MILAS score at diagnosis was associated with early death (< 1 year). CONCLUSION: Baseline cerebellar metabolism and sumMTV may predict response to end of chemotherapy in PCNSL. Tumor volume and MILAS at baseline are strong prognostic factors.

Facial nerve stimulation in adult cochlear implant recipients with far advanced otosclerosis.

Objectives: The objective of this study was to predict occurrence of facial nerve stimulation (FNS) in cochlear implanted patients for far-advanced otosclerosis (FAO) by correlating preoperative computed tomography (CT)-scan data to FNS and to evaluate FNS impact on hearing outcomes. Methods: Retrospective analysis on 91 ears (76 patients) implanted for FAO. Electrodes were straight (50%) or perimodiolar (50%). Demographic data, extension of otosclerosis on preoperative CT scan, occurrence of FNS, and speech performance were analyzed. Results: Prevalence of FNS was 21% (19 ears). FNS appeared during the first month (21%), 1-6 months (26%), 6-12 months (21%), and over 1 year (32%) postimplantation. Cumulative incidence of FNS at 15 years was 33% (95% CI = [14-47%]). Extension of otosclerotic lesions on preimplantation CT-scan was more severe in FNS ears compared to No-FNS (p < .05): for Stage III, 13/19 (68%) and 18/72 (25%) ears for FNS and No-FNS groups, respectively (p < .05). Location of otosclerotic lesions relative to the facial nerve canal was similar whatever the presence or not of FNS. Electrode array had no impact on FNS occurrence. At 1 year post-implantation, duration of profound hearing loss (≥5 years) and previous stapedotomy were negatively associated with speech performance. FNS did not impact hearing outcomes, despite a lower percentage of activated electrodes (p < .01) in the FNS group. Nevertheless, FNS were associated with a decrease of speech performance both in quiet (p < .001) and in noise (p < .05). Conclusion: Cochlear implanted patients for FAO are at greater risk of developing FNS affecting speech performance over time, probably due to a higher percentage of deactivated electrodes. High resolution CT-scan is an essential tool allowing FNS prediction but not time of onset. Level of evidence: 2b, Laryngoscope Investigative Otolaryngology, 2022.

Clinical and Virological Characteristics and Prognostic Factors in Viral Necrotizing Retinitis.

Purpose: Describe the clinical and virological characteristics of viral necrotizing retinitis (VNR) and assess its prognostic factors. Methods: Retrospective study (Pitié Salpêtrière Hospital, Paris) of consecutive VNR patients diagnosed and monitored by qPCR on aqueous humor between 2015 and 2019. All patients received induction therapy with intravenous +/− intravitreal injections (IVI) of antivirals. Results: Forty-one eyes of 37 patients with a mean age of 56 years were included. Involved viruses were VZV (44%), CMV (37%) and HSV2 (19%). Acute retinal necrosis represented 51%, progressive outer retinal necrosis 12% and CMV retinitis 37% of eyes. Forty-six percent of patients were immunocompromised. Median BCVA was 0.7 LogMAR at baseline and 0.8 LogMAR after an average of 14.1 months. VNR bilateralized in 27% of cases after 32 months. Retinal detachment (RD) occurred in 27% of cases after a mean duration of 98 days. Factors associated with a "poor BCVA" at 1 month were: advanced age, low baseline BCVA, high vitritis grade and viral load (VL) at baseline and the "slow responder" status (i.e., VL decrease <50% after 2 weeks of treatment). Factors associated with RD were: advanced age, immunocompetence, low baseline BCVA, high vitritis grade at baseline and use of ≤5 IVIs. Conclusions: Clinical factors including advanced age, immunocompetence, low BCVA and high vitritis grade at baseline were associated with a poor prognosis. New virological factors were predictive of a poor outcome: high baseline VL and the "slow responder" status. Sequential intraocular fluid sampling might help prognosticate the outcomes of VNR.

Growth of home respiratory equipment from 2006 to 2019 and cost control by health policies.

BACKGROUND: Home respiratory equipment (HRE) designed for the management of chronic respiratory failure includes oxygen therapy (O2), noninvasive ventilation (NIV) and mechanical insufflation-exsufflation (MI-E). The growth of the number of patients treated by HRE, the prevalence and the associated costs in France have not been determined. METHODS: The French open access national health insurance aggregated data was used to estimate the evolution of theses parameters from 2006 to 2019. RESULTS: The number of patients treated by HRE increased by 117% between 2006 and 2019, reaching a total of 245,896 patients (367/100,000). Prescriptions for O2, NIV, and MI-E increased by 88%, 189% and 162%, respectively. In 2019, 139,323 patients received long-term home O2 alone (208/100,000) with a 13% decrease for liquid O2 compared to a 44% increase for O2 concentrator. The number of patients treated by portable oxygen concentrator increased by 509% over the last 5 years. In 2019, 96,126 patients received NIV (144/100,000) and 97% of these patients were treated by NIV for less than 12 h/day. A total of 9,158 patients were treated by MI-E in 2019 (13.6/100,000). Despite the global increase in the number of patients, health costs decreased from 9% to 8% of total medical device spending in 2019 due to adjustment of health policies, such as a reduction of reimbursement rates. CONCLUSION: Our results highlighted the high rate of HRE prescription, but with cost control as a result of adapted health policies.

Immunochemotherapy versus rituximab in anti-myelin-associated glycoprotein neuropathy: A report of 64 patients.

Monoclonal immunoglobulin M (IgM) anti-myelin-associated glycoprotein (MAG) neuropathy is a rare disabling condition, most commonly treated with rituximab monotherapy (R), which leads to neurological improvement in only 30%-50% of patients. The combination of rituximab plus chemotherapy has been proven to improve the level of responses. We studied the outcomes of anti-MAG neuropathy patients treated either by R, or by immunochemotherapy (ICT) in our centre, focusing on the incidence of the first neurological response evaluated by the modified Rankin scale (mRS). From 2011 to 2018, 64 patients were studied: 34 were treated with R and 30 with ICT. According to our treatment decision-making process, the median mRS was higher in the ICT group (mRS 2) than in the R group (mRS 1). At one year, improvements of the mRS rates were 46% and 18% in the ICT and R groups of patients respectively, with median times to response of eight and 13 months (p = 0.023). Adverse effects were higher in the ICT group: 62% vs 15% (p Ë‚ 0.01), all grades included. One secondary acute leukaemia occurred five years after treatment with ICT. In conclusion, ICT may be used as a valid option for patients with rapidly progressive and/or severe anti-MAG neuropathy symptoms.

Weaning-Related Shock in Patients With ECMO: Incidence, Mortality, and Predisposing Factors.

OBJECTIVE: Venoarterial extracorporeal membrane oxygenation (VA-ECMO) commonly is used to manage refractory cardiogenic shock after cardiac surgery, with 31% to 76% of patients successfully weaned off their ECMO. However, it is associated with high mortality rates, and 20% to 65% of weaned patients do not survive to hospital discharge. This study aimed to assess the incidence of ECMO weaning-related shock, the risk factors, and prognosis in the intensive care unit (ICU). DESIGN: Retrospective observational cohort study. SETTING: Surgical ICU of Cardiology Institute of Pitié-Salpêtrière University Hospital (Paris-France). PARTICIPANTS: Patients who were assisted with a peripheral VA-ECMO from January 2015 to December 2017 were included. Patients with venovenous, central, or right ECMO were excluded. MEASUREMENTS: The authors collected data on patients' characteristics, during and after surgery. The indications for VA-ECMO implantation were ventricular dysfunction, primary graft dysfunction, and refractory cardiac arrest. Weaning-related shock was defined as the need to introduce or increase the dose of catecholamine at ECMO explantation or in the following week. RESULTS: After weaning off VA-ECMO, 56 of 146 patients (38.4%) presented weaning-related shock: 55% were septic shocks, 12.5 % were caused by right ventricle failure, and 7.1% by hemorrhage. ICU mortality was 42% versus 8% in patients who did not present shock. Multivariate analysis showed that patients with pulmonary hypertension and those with norepinephrine before weaning were more likely to develop shock. CONCLUSION: ECMO weaning-related shock is frequent in patients with refractory cardiogenic shock after cardiac surgery. This is most commonly caused by sepsis and causes higher mortality rates, calling for further evaluation.

Compassionate Use of Hydroxychloroquine in Clinical Practice for Patients With Mild to Severe COVID-19 in a French University Hospital.

BACKGROUND: Data from nonrandomized studies have suggested that hydroxychloroquine could be an effective therapeutic agent against coronavirus disease 2019 (COVID-19). METHODS: We conducted an observational, retrospective cohort study involving hospitalized adult patients with confirmed, mild to severe COVID-19 in a French university hospital. Patients who received hydroxychloroquine (200 mg 3 times daily dosage for 10 days) on a compassionate basis in addition to standard of care (SOC) were compared with patients without contraindications to hydroxychloroquine who received SOC alone. A propensity score-weighted analysis was performed to control for confounders: age, sex, time between symptom onset and admission ≤ 7 days, Charlson comorbidity index, medical history of arterial hypertension, obesity, National Early Warning Score 2 (NEWS2) score at admission, and pneumonia severity. The primary endpoint was time to unfavorable outcome, defined as: death, admission to an intensive care unit, or decision to withdraw or withhold life-sustaining treatments, whichever came first. RESULTS: Data from 89 patients with laboratory-confirmed COVID-19 were analyzed, 84 of whom were considered in the primary analysis; 38 patients treated with hydroxychloroquine and 46 patients treated with SOC alone. At admission, the mean age of patients was 66 years, the median Charlson comorbidity index was 3, and the median NEWS2 severity score was 3. After propensity score weighting, treatment with hydroxychloroquine was not associated with a significantly reduced risk of unfavorable outcome (hazard ratio, 0.90 [95% confidence interval, .38-2.1], P = .81). Overall survival was not significantly different between the 2 groups (hazard ratio, 0.89 [0.23; 3.47], P = 1). CONCLUSION: In hospitalized adults with COVID-19, no significant reduction of the risk of unfavorable outcomes was observed with hydroxychloroquine in comparison to SOC. Unmeasured confounders may have persisted however, despite careful propensity-weighted analysis and the study might be underpowered. Ongoing controlled trials in patients with varying degrees of initial severity on a larger scale will help determine whether there is a place for hydroxychloroquine in the treatment of COVID-19. In hospitalized adults with COVID-19, no significant reduction of the risk of unfavorable outcomes was observed with hydroxychloroquine in comparison to SOC.

Relationship between vitamin D status in pregnancy and the risk for preeclampsia: A nested case-control study.

BACKGROUND & AIMS: Vitamin D is thought to be involved in the pathogenesis of preeclampsia. To evaluate the relationship between vitamin D insufficiency in the first trimester of pregnancy and preeclampsia. METHODS: Nested case-control study (FEPED study) in type 3 obstetrical units. Pregnant women from 10 to 15 WA. For each patient with preeclampsia, 4 controls were selected from the cohort and matched by parity, skin color, maternal age, season and BMI. The main outcome measure was serum 25(OH)D status in the first trimester. RESULTS: 83 cases of preeclampsia were matched with 319 controls. Mean 25(OH)D levels in the first trimester were 20.1 ± 9.3 ng/mL in cases and 22.3 ± 11.1 ng/mL in controls (p = 0.09). The risk for preeclampsia with 25(OH)D level ≥30 ng/mL in the first trimester was decreased, but did not achieve statistical significance (OR, 0.57; 95% CI, 0.30-1.01; p = 0.09). High 25(OH)D during the 3rd trimester was associated with a significantly decreased risk of preeclampsia (OR, 0.43; 95%CI, 0.23-0.80; p = 0.008). When women with 25(OH)D levels <30 ng/mL both in the first and 3rd trimesters ("low-low") were taken as references, OR for preeclampsia was 0.59 (95% CI, 0.31-1.14; p = 0.12) for "low-high" or "high-low" women and 0.34 (95% CI, 0.13-0.86; p = 0.02) for "high-high" women. CONCLUSIONS: No significant association between preeclampsia and vitamin D insufficiency in the first trimester was evidenced. However, women with vitamin D sufficiency during the 3rd trimester and both in the first and 3rd trimesters had a significantly lower risk of preeclampsia.

First Trimester Maternal Vitamin D Status and Risks of Preterm Birth and Small-For-Gestational Age.

Maternal 25-hydroxyvitamin D (25-OHD) deficiency during pregnancy may increase the risk of preterm and small-for-gestational age (SGA) birth, but studies report conflicting results. We used a multicenter prospective cohort of 2813 pregnant women assessed for 25-OHD levels in the first trimester of pregnancy to investigate the association between maternal 25-OHD concentrations and risks of preterm birth (<37 weeks) and SGA (birthweight <10th percentile). Odds ratios were adjusted (aOR) for potential cofounders overall and among women with light and dark skin separately, based on the Fitzpatrick scale. 25-OHD concentrations were <20 ng/mL for 45.1% of the cohort. A total of 6.7% of women had a preterm birth. The aOR for preterm birth associated with the 1st quartile of 25-OHD concentrations compared to the 4th quartile was 1.53 (95% confidence interval (CI): 0.97-2.43). In stratified analyses, an association was observed for women with darker skin (aOR = 2.89 (95% CI: 1.02-8.18)), and no association with lighter skin. A total of 11.9% of births were SGA and there was no association overall or by skin color. Our results do not provide support for an association between maternal first trimester 25-OHD deficiency and risk of preterm or SGA birth overall; the association with preterm birth risk among women with darker skin requires further investigation.

MRI for prostate cancer: can computed high b-value DWI replace native acquisitions?

OBJECTIVE: To compare computed high b-value diffusion-weighted images (c-DWI) derived from low b-value DWI images and acquired high b-value DWI (a-DWI), in overall image quality and prostate cancer detection rate. MATERIALS AND METHODS: A total of 124 consecutive men with suspected prostate cancer (PCa) underwent diagnosis prostate MRI on a 3.0 T MR system using a 32-channel phased-array torso coil. Among them, 63 underwent prostate biopsy. MRI protocol included 3DT2w images, high resolution Fov Optimized and Constrained Undistorted Single-Shot (FOCUS™) DWI images with b-values of 100, 400, 800, and 2000 s/mm2 and dynamic contrast enhanced images. C-DWI images (2000 and 2500 s/mm2) were derived from the three lower acquired b-value DWI images using a mono-exponential diffusion decay. C-DWI and acquired high b-value DWI (a-DWI) (2000 s/mm2) were compared for image quality (background signal suppression, anatomic clarity, ghosting, distortion) and tumor conspicuity by four radiologists. RESULTS: C-DWIs demonstrated higher rating than a-DWIs for overall image quality despite worsened ghosting. In patients with a biopsy, similar detection rate was observed while conspicuity was better with c-DWI (p < 0.001). Non-acquisition of high b-value a-DWI reduced total acquisition time by 220 s per patient. CONCLUSION: C-DWI provides a substantial reduction in acquisition time while maintaining comparable prostate cancer detection rate and improving global image quality. KEY POINTS: • Computed DWI improves global quality of prostate MRI. • Computed DWI improves analysis of DWI images with decrease acquisition time. • Computed DWI provides greater background suppression of parenchyma and improves conspicuity of suspicious lesion.

Glibenclamide oral suspension: Suitable and effective in patients with neonatal diabetes.

BACKGROUND: Results of genetic have led to off-label glibenclamide treatment in patients with neonatal diabetes (NDM) because of potassium channel mutations. No pediatric form of glibenclamide was available. Glibenclamide was designated an orphan drug designation for NDM and a suspension was developed. As a part of the pediatric plan investigation, we assessed its acceptability, efficiency, and safety. METHODS: In this Phase II, prospective, non-randomized, single-center study, patient received glibenclamide tablets for 1 month then the suspension for 3 months. We assessed acceptability using hedonic scales and patient questionnaires, effectiveness using glycated hemoglobin (HbA1C) assays and safety based on hypo and hyperglycemia, and other adverse events. RESULTS: We included 10 patients (0.1-16.2 years, 6 < 5 years) were included. Younger patients preferred the suspension and older the tablets. All parents were satisfied with the ease of suspension administration. The parents of 5 of 6 younger children preferred the suspension over the tablets and kept it. Switching from tablets to suspension did not affect the excellent metabolic control (median HbA1c change, -0.40%, [-1.3% to 0.5%] P = 0.08). Median frequencies of hypoglycemia and hyperglycemia were less than 5% of routine blood glucose assays and were similar with both dosage forms. Two patients each experienced one episode of hypoglycemia below 35 mg/dL highlighting the need for dosage titration when switching from tablets to suspension. Transient and non-severe abdominal pain or diarrhea occurred in three patients. None of the patients discontinued the treatment. CONCLUSION: The glibenclamide oral suspension Amglidia, the first anti-diabetic drug specifically developed for pediatric patients, is acceptable, effective, and safe in patients with NDM (NCT02375828).

Vitamin D status during pregnancy and in cord blood in a large prospective French cohort.

BACKGROUND & AIMS: Vitamin D status during pregnancy and in newborns has never been studied in France. This study aims at determining the vitamin D status during the first and third trimesters of pregnancy (T1, T3) and in cord blood (CB) in the middle-north of France. METHODS: We conducted a prospective cohort study in five French centers (latitude 47.22 to 48.86°N). Serum 25(OH)-vitamin D (25(OH)D) concentrations were measured using a radioimmunoassay during T1, T3 and in CB. According to the French guidelines, pregnant women received cholecalciferol, 100,000 IU, in the seventh month. RESULTS: Between April 2012 and July 2014, 2832 women were included, of whom 2803 were analyzed (mean ± SD age: 31.5 ± 5.0 years; phototypes 5-6: 21.8%). Three and 88.6% of participants received supplementation during the month before inclusion and in the seventh month, respectively. At T1, T3, and CB, mean 25(OH)D concentrations were 21.9 ± 10.4, 31.8 ± 11.5, and 17.0 ± 7.2 ng/mL, respectively, and 25(OH)D was <20 ng/mL in 46.5%, 14.0%, and 68.5%, respectively. At T1, body mass index ≥25 kg/m2, dark phototypes, sampling outside summer, and no supplementation before inclusion were independently associated with vitamin D insufficiency (25(OH)D < 20 ng/mL). Women who received cholecalciferol supplementation in month 7 had higher 25(OH)D at T3 than non-supplemented women (32.5 ± 11.4 versus 25.8 ± 11.4 ng/mL, p = <0.001) and marginally higher 25(OH)D in CB (17.2 ± 7.2 versus 15.5 ± 7.1 ng/mL, p = 0.004). CONCLUSIONS: Despite the recommended supplementation, vitamin D insufficiency is frequent during pregnancy and in newborns in France.

Prenatal education of overweight or obese pregnant women to prevent childhood overweight (the ETOIG study): an open-label, randomized controlled trial.

BACKGROUND: We aimed to evaluate whether pre and perinatal education of pregnant women would reduce childhood overweight. METHODS: Four French centers included women at ≤21 gestational weeks (GWs) with body mass index (BMI) >25 kg/m2 before pregnancy. Patients were randomized to a control group (routine care including at least one dietary visit) or an intervention group (2 individuals (26 and 30 GW) and 4 group sessions (21, 28, 35 GW, 2 months postpartum)) aimed at educating the future mother regarding infant and maternal nutrition. The primary objective was to reduce post-natal excessive weight gain in the infant from birth to 2 years (NCT00804765). This project was funded by a grant from the National Programme for Hospital Research (PHRC-2007 French Ministry of Health). RESULTS: We included 275 women (BMI: 32.5 kg/m2). The rate of post-natal excessive weight gain was similar in the intervention (n = 132) and control (n = 136) groups by intention to treat (ITT: 59.1% vs 60.3% respectively, p = 0.84) in available data (AD, n = 206) and by per-protocol analysis (PP, n = 177). Two years after delivery, normalization of maternal BMI and number of infants with BMI < 19 kg/m2 were not significantly different in the interventional group in ITT and in the control group. Although not significantly different in ITT, normalization of maternal BMI was more frequent in AD (n = 149: 12.9% vs 3.8%, p = 0.04) and 2-year-old infant BMIs were less likely to be >19 kg/m2 in the intervention group in AD (n = 204: 0% vs 6.8%, p = 0.014) and PP (n = 176: 0% vs 6.4%, p = 0.03). CONCLUSIONS: An education and nutritional counseling program for overweight women, starting after 3 months of gestation, did not significantly change post-natal excessive weight gain of infants or prevent overweight in mothers and children 2 years after delivery.

Sedative-hypnotic initiation and renewal at discharge in hospitalized older patients: an observational study.

BACKGROUND: Sedative-hypnotics (SHs) are widely used in France but there are no available data addressing their prescription specifically in hospitalized older patients. The objective is thus to determine the cumulative incidence of sedative-hypnotic (SH) medications initialized during a hospital stay of older patients, the proportion of SH renewal at discharge among these patients and to study associated risk factors. METHODS: We conducted a retrospective observational study in six internal medicine units and six acute geriatric units in eight hospitals (France). We included 1194 inpatients aged 65 and older without SH medications prior to hospitalization. Data were obtained from patients' electronic pharmaceutical records. Primary outcome was the cumulative incidence of SH initiation in the study units. Secondary outcomes were the proportion of SH renewal at discharge and risk factors for SH initiation and renewal at discharge (patient characteristics, hospital organization). A Cox regression model was used to study risk factors for SH initiation. A mixed effects logistic regression was used to study risk factors for SH renewal at discharge. RESULTS: SH initiation occurred in 21.5% of participants 20 days after admission. SH renewal at discharge occurred in 38.7% of patients who had initiated it during their stay and were discharged home and in 56.0% of patients discharged to rehabilitation facilities. Neither patients' characteristics nor hospital organization patterns was associated with SH initiation. SH initiation after the first six days after admission was associated with a lower risk of SH renewal in patients discharged to rehabilitation facilities (OR = 0.19, 95% CI: [0.04-0.80]). CONCLUSIONS: Hospitalization is a period at risk for SH initiation. The implementation of interventions promoting good use of SHs is thus of first importance in hospitals. Specific attention should be paid to patients discharged to rehabilitation facilities.

Effect of Cell-Free DNA Screening vs Direct Invasive Diagnosis on Miscarriage Rates in Women With Pregnancies at High Risk of Trisomy 21: A Randomized Clinical Trial.

Importance: Cell-free DNA (cfDNA) tests are increasingly being offered to women in the first trimester of pregnancies at a high risk of trisomy 21 to decrease the number of required invasive fetal karyotyping procedures and their associated miscarriages. The effect of this strategy has not been evaluated. Objective: To compare the rates of miscarriage following invasive procedures only in the case of positive cfDNA test results vs immediate invasive testing procedures (amniocentesis or chorionic villus sampling) in women with pregnancies at high risk of trisomy 21 as identified by first-trimester combined screening. Design, Setting, and Participants: Randomized clinical trial conducted from April 8, 2014, to April 7, 2016, in 57 centers in France among 2111 women with pregnancies with a risk of trisomy 21 between 1 in 5 and 1 in 250 following combined first-trimester screening. Interventions: Patients were randomized to receive either cfDNA testing followed by invasive testing procedures only when cfDNA tests results were positive (n = 1034) or to receive immediate invasive testing procedures (n = 1017). The cfDNA testing was performed using an in-house validated method based on next-generation sequencing. Main Outcomes and Measures: The primary outcome was number of miscarriages before 24 weeks' gestation. Secondary outcomes included cfDNA testing detection rate for trisomy 21. The primary outcome underwent 1-sided testing; secondary outcomes underwent 2-sided testing. Results: Among 2051 women who were randomized and analyzed (mean age, 36.3 [SD, 5.0] years), 1997 (97.4%) completed the trial. The miscarriage rate was not significantly different between groups at 8 (0.8%) vs 8 (0.8%), for a risk difference of -0.03% (1-sided 95% CI, -0.68% to ∞; P = .47). The cfDNA detection rate for trisomy 21 was 100% (95% CI, 87.2%-100%). Conclusions and Relevance: Among women with pregnancies at high risk of trisomy 21, offering cfDNA screening, followed by invasive testing if cfDNA test results were positive, compared with invasive testing procedures alone, did not result in a significant reduction in miscarriage before 24 weeks. The study may have been underpowered to detect clinically important differences in miscarriage rates. Trial Registration: ClinicalTrials.gov Identifier: NCT02127515.

Surgery is not superior to dilation for the management of vaginal agenesis in Mayer-Rokitansky-Küster-Hauser syndrome: a multicenter comparative observational study in 131 patients.

BACKGROUND: Vaginal agenesis in Mayer-Rokitansky-Küster-Hauser syndrome can be managed either by various surgeries or dilation. The choice still depends on surgeon's preferences rather than on quality comparative studies and validated protocols. OBJECTIVE: We sought to compare dilation and surgical management of vaginal agenesis in Mayer-Rokitansky-Küster-Hauser syndrome, in terms of quality of life, anatomical results, and complications in a large multicenter population. STUDY DESIGN: Our multicenter study included 131 patients >18 years, at least 1 year after completing vaginal agenesis management. All had an independent gynecological evaluation including a standardized pelvic exam, and completed the World Health Organization Quality of Life instrument (general quality of life) as well as the Female Sexual Function Index and Female Sexual Distress Scale-Revised (sexual quality of life) scales. Groups were: surgery (N = 84), dilation therapy (N = 26), and intercourse (N = 20). One patient was secondarily excluded because of incomplete surgical data. For statistics, data were compared using analysis of variance, Student, Kruskal-Wallis, Wilcoxon, and Student exact test. RESULTS: Mean age was 26.5 ± 5.5 years at inclusion. In all groups, World Health Organization Quality of Life scores were not different between patients and the general population except for lower psychosocial health and social relationship scores (which were not different between groups). Global Female Sexual Function Index scores were significantly lower in the surgery and dilation therapy groups (median 26 range [2.8-34.8] and 24.7 [2.6-34.4], respectively) than the intercourse group (30.2 [7.8-34.8], P = .044), which had a higher score only in the satisfaction dimension (P = .004). However, the scores in the other dimensions of Female Sexual Function Index were not different between groups. The Female Sexual Distress Scale-Revised median scores were, respectively, 17 [0-52], 20 [0-47], and 10 [10-40] in the surgery, dilation therapy, and intercourse groups (P = .38), with sexual distress in 71% of patients. Median vaginal depth was shorter in dilatation therapy group (9.6 cm [5.5-12]) compared to surgery group (11 cm [6-15]) and intercourse group (11 cm [6-12.5]) (P = .039), but remained within normal ranges. One bias in the surgery group was the high number of sigmoid vaginoplasties (57/84, 68%), but no differences were observed between surgeries. Only 4 patients achieved vaginas <6.5 cm. Delay between management and first intercourse was 6 months (not significant). Seventy patients (53%) had dyspareunia (not significant), and 17 patients all from the surgery group had an abnormal pelvic exam. In the surgery group, 34 patients (40.5%) had complications, requiring 20 secondary surgeries in 17 patients, and 35 (42%) needed postoperative dilation. In the dilation therapy group, 13 (50%) needed maintenance dilation. CONCLUSION: Surgery is not superior to therapeutic or intercourse dilation, bears complications, and should therefore be only a second-line treatment. Psychological counseling is mandatory at diagnosis and during therapeutic management.
