RESUMO
BACKGROUND: Electroconvulsive therapy (ECT) is one of the most effective treatments for treatment-resistant depression (TRD). However, due to response delay and cognitive impairment, ECT remains an imperfect treatment. Compared to ECT, repetitive transcranial magnetic stimulation (rTMS) is less effective at treating severe depression, but has the advantage of being quick, easy to use, and producing almost no side effects. In this study, our objective was to assess the priming effect of rTMS sessions before ECT on clinical response in patients with TRD. METHODS: In this multicenter, randomized, double-blind, sham-controlled trial, 56 patients with TRD were assigned to active or sham rTMS before ECT treatment. Five sessions of active/sham neuronavigated rTMS were administered over the left dorsolateral prefrontal cortex (20 Hz, 90% resting motor threshold, 20 2 s trains with 60-s intervals, 800 pulses/session) before ECT (which was active for all patients) started. Any relative improvements were then compared between both groups after five ECT sessions, in order to assess the early response to treatment. RESULTS: After ECT, the active rTMS group exhibited a significantly greater relative improvement than the sham group [43.4% (28.6%) v. 25.4% (17.2%)]. The responder rate in the active group was at least three times higher. Cognitive complaints, which were assessed using the Cognitive Failures Questionnaire, were higher in the sham rTMS group compared to the active rTMS group, but this difference was not corroborated by cognitive tests. CONCLUSIONS: rTMS could be used to enhance the efficacy of ECT in patients with TRD. ClinicalTrials.gov: NCT02830399.

OBJECTIVES: To determine a potential window of opportunity for retreatment with rituximab in patients with rheumatoid arthritis (RA) from a multicentre longitudinal real-life study based on tight monitoring with ultrasonography (US). METHODS: Thirty RA patients treated with rituximab were included. US parameters were collected at each time (8 visits) of the 18-month follow-up, notably the global score of power Doppler (PD) activity. Clinical relapse was defined as a DAS28 ESR of >3.2 after 6 months in responders while US relapse was defined as an increase of ≥20% of the global score of PD activity. The decision of retreatment was based exclusively on clinical findings. RESULTS: A total of 29 patients were analysed (mean (SD) age: 57.2 (12.2) years; female gender: 66%). The mean (SD) PD score decreased from 8.8 (5.2) at baseline to 4.9 (4.3) at 6 months (p <0.0001). A clinical response was observed at Month 4 or Month 6 for 93% of patients. A total of 19 patients had a first clinical relapse (with or without US relapse) after Month 6 (18 of them were retreated with rituximab). Among 10 patients without clinical relapse, 3 had US relapse (only one was retreated) and 7 had no US relapse (but 4 were retreated). CONCLUSIONS: This study highlights a great heterogeneity in terms of sequence of clinical relapse, US relapse and retreatment in RA patients receiving rituximab. Therefore, US monitoring does not seem to be relevant to determine the best time for retreatment with rituximab.

BACKGROUND: Adverse pregnancy outcomes (APO) occur in 35% of patients with pemphigoid gestationis (PG). No biological predictor of APO has been established yet. OBJECTIVES: To assess a potential relationship between the occurrence of APO and the serum value of anti-BP180 antibodies at the time of PG diagnosis. METHODS: Multicentre retrospective study conducted from January 2009 to December 2019 in 35 secondary and tertiary care centres. INCLUSION CRITERIA: (i) diagnosis of PG according to clinical, histological and immunological criteria, (ii) ELISA measurement of anti-BP180 IgG antibodies determined at the time of PG diagnosis with the same commercial kit and (iii) obstetrical data available. RESULTS: Of the 95 patients with PG included, 42 had one or more APO, which mainly corresponded to preterm birth (n = 26), intrauterine growth restriction (IUGR) (n = 18) and small weight for gestational age at birth (n = 16). From a ROC curve, we identified a threshold of 150 IU ELISA value as the most discriminating to differentiate between patients with or without IUGR, with 78% sensitivity, 55% specificity, 30% positive and 91% negative predictive value. The threshold >150 IU was confirmed using a cross-validation based on bootstrap resampling, which showed that the median threshold was 159 IU. Upon adjusting for oral corticosteroid intake and main clinical predictors of APO, an ELISA value of >150 IU was associated with the occurrence of IUGR (OR = 5.11; 95% CI: 1.48-22.30; p = 0.016) but not with any other APO. The combination of blisters and ELISA values higher than 150 IU led to a 2.4-fold higher risk of all-cause APO (OR: 10.90; 95% CI: 2.33-82.3) relative to patients with blisters but lower values of anti-BP180 antibodies (OR of 4.54; 95% CI 0.92-34.2). CONCLUSION: These findings suggest that anti-BP180 antibody ELISA value in combination with clinical markers is helpful in managing the risk of APO, in particular IUGR, in patients with PG.

Cohort and nested case-control (NCC) designs are frequently used in pharmacoepidemiology to assess the associations of drug exposure that can vary over time with the risk of an adverse event. Although it is typically expected that estimates from NCC analyses are similar to those from the full cohort analysis, with moderate loss of precision, only few studies have actually compared their respective performance for estimating the effects of time-varying exposures (TVE). We used simulations to compare the properties of the resulting estimators of these designs for both time-invariant exposure and TVE. We varied exposure prevalence, proportion of subjects experiencing the event, hazard ratio, and control-to-case ratio and considered matching on confounders. Using both designs, we also estimated the real-world associations of time-invariant ever use of menopausal hormone therapy (MHT) at baseline and updated, time-varying MHT use with breast cancer incidence. In all simulated scenarios, the cohort-based estimates had small relative bias and greater precision than the NCC design. NCC estimates displayed bias to the null that decreased with a greater number of controls per case. This bias markedly increased with higher proportion of events. Bias was seen with Breslow's and Efron's approximations for handling tied event times but was greatly reduced with the exact method or when NCC analyses were matched on confounders. When analyzing the MHT-breast cancer association, differences between the two designs were consistent with simulated data. Once ties were taken correctly into account, NCC estimates were very similar to those of the full cohort analysis.

BACKGROUND: We aimed to assess the personal and professional quality of life changes among health care workers of different professions during the COVID-19 pandemic in a large French university hospital. Other published data originated from countries with different health care systems and outbreak dynamics. METHODS: All health care workers from our hospital were invited to fill-in an anonymous e-questionnaire of 71 questions regarding perceived personal, professional and overall quality of life before and during the first COVID-19 wave, general profile, occupation and job characteristics, change of assignment, COVID-care features if relevant, general perception during the first wave, and personal experience of being encouraged or stigmatised. RESULTS: There were 794 participants, with a majority of nursing professionals (n = 416, 56%), including 57 nurse managers, 243 nurses, and 116 nurse assistants. Other participants were physicians (n = 188) and other health care staff (n = 140). Before the crisis, professional quality of life was low (6.5 on a 10-point scale) overall. The personal quality of life was higher (8.1) particularly for physicians and nurse managers. The COVID crisis saw a marked decrease in the personal quality of life (- 1.7), more pronounced in younger health care workers. Professional quality of life was less affected (- 0.4) and stayed almost constant for physicians. Staff in COVID units had a more positive perception of the crisis but experienced more fatigue, which resulted in similar quality of life levels in COVID and non-COVID units. Encouragements originated more often from relatives or colleagues than hospital managers and were exceptionally common: 63.4% of all participants, from 50.5% for other staff to 71.3% for physicians (p = 0.0005). Stigmatisation was reported by 19.3% of participants, with a higher proportion (p = 0.0001) among nurses (26.3%) and assistant nurses (23.3%) than among physicians (8.5%). From multivariate analysis, higher age, working as a physician and receiving encouragements were independently associated with lower loss of overall quality of life. CONCLUSIONS: The resilience of health care workers was high overall during the first COVID wave although the quality of life decreased more among nursing staff. Social support in the form of encouragements is a key part of management, particularly in times of crisis.
RESUMO
Background and Purpose: The objective of the study was to assess the effectiveness of individual direct oral anticoagulants versus vitamin K antagonists for primary prevention of stroke (ischemic and hemorrhagic) in routine clinical practice in patients with various clinical risk factors depending on their atrial fibrillation (AF) patterns. Methods: A nested case-referent study was conducted using data from 2 national registries of patients with stroke and AF. Stroke cases with previous history of AF were matched to up to 2 randomly selected referent patients with AF and no stroke. The association of individual anticoagulant use with ischemic or hemorrhagic stroke was studied in patients with or without permanent AF using multivariable conditional logistic models, controlled for clinically significant risk factors and multiple other cardiovascular risk factors. Results: In total, 2586 stroke cases with previous AF and 4810 nonstroke referent patients with AF were retained for the study. Direct oral anticoagulant users had lower odds of stroke of any type than vitamin K antagonist users: the adjusted-matched OR for ischemic stroke were 0.70 (95% CI, 0.500.98) for dabigatran, 0.68 (95% CI, 0.530.86) for rivaroxaban, and 0.73 (95% CI, 0.521.02) for apixaban while for hemorrhagic stroke they were 0.31 (95% CI, 0.140.68), 0.64 (95% CI, 0.391.06), and 0.70 (95% CI, 0.331.49), respectively. The effects of individual direct oral anticoagulants relative to vitamin K antagonists were similar in permanent AF and nonpermanent AF patients. Conclusions: Similar results were observed for each direct oral anticoagulant in real life as those observed in the pivotal clinical trials. The pattern of AF did not affect the outcome.

BACKGROUND: We previously reported that CEA kinetics are a marker of progressive disease (PD) in metastatic colorectal cancer (mCRC). This study was specifically designed to confirm CEA kinetics for predicting PD and to evaluate CA19-9, cell-free DNA (cfDNA), circulating tumour DNA (ctDNA) and circulating tumour cell (CTC) kinetics. METHODS: Patients starting a chemotherapy (CT) with pre-treatment CEA > 5 ng/mL and/or CA19.9 > 30 UI/mL were prospectively included. Samples were collected from baseline to cycle 4 for CEA and CA19-9 and at baseline and the sixth week for other markers. CEA kinetics were calculated from the first to the third or fourth CT cycle. RESULTS: A total of 192 mCRC patients were included. CEA kinetics based on the previously identified >0.05 threshold was significantly associated with PD (p < 0.0001). By dichotomising by the median value, cfDNA, ctDNA and CA19-9 were associated with PD, PFS and OS in multivariate analysis. A circulating scoring system (CSS) combining CEA kinetics and baseline CA19-9 and cfDNA values classified patients based on high (n = 58) and low risk (n = 113) of PD and was independently associated with PD (ORa = 4.6, p < 0.0001), PFS (HRa = 2.07, p < 0.0001) and OS (HRa = 2.55, p < 0.0001). CONCLUSIONS: CEA kinetics alone or combined with baseline CA19-9 and cfDNA are clinically relevant for predicting outcomes in mCRC. TRIAL REGISTRATION NUMBER: NCT01212510.

BACKGROUND: No long-term maintenance therapy has been tested in patients with seborrheic dermatitis (SD). OBJECTIVE: We sought to compare the efficacy and tolerance of tacrolimus 0.1% ointment versus ciclopiroxolamine 1% cream as maintenance therapy for severe SD. METHODS: This double-blind randomized controlled study was conducted from 2014 to 2017 in 5 Dermatology Departments and 15 dermatology practices in France. Consecutive patients with severe and chronic facial SD were included. Patients were initially treated with desonide 0.05% cream twice daily for 7 days. Patients cleared after this open phase were randomized to receive tacrolimus 0.1% or ciclopiroxolamine 1% cream 2 times a week 24 weeks. The primary endpoint was disease-free-duration, defined as the time from randomization to first relapse. RESULTS: One hundred fourteen patients were randomized (tacrolimus, n = 57; ciclopiroxolamine, n = 57). Twelve patients relapsed in the tacrolimus group after a median delay of 91.5 days (range 15-195 days) versus 23 patients in the ciclopiroxolamine group (median delay, 27 days [range 13-201 days]). Comparison of disease-free duration curves showed that patients in the tacrolimus group had a longer duration of complete remission than those in the ciclopiroxolamine group (P = .018), corresponding to a hazard ratio of relapse of 0.44 (95% confidence interval 0.22-0.89; P = .022). LIMITATIONS: The theoretical sample size was not reached. CONCLUSION: Tacrolimus 0.1% is more effective than ciclopiroxolamine 1% as maintenance therapy for patients with facial SD.

Many pregnant women, in the world, drink caffeine-containing beverages. Maternal caffeine consumption during pregnancy may have adverse effects on foetus but results are conflicting. Our goals were to estimate the prevalence of caffeine use in a cohort of French pregnant women using maternal self-reports and to evaluate the association between caffeine consumption during pregnancy and delivery and newborn characteristics. All pregnant women who gave birth in a large French urban area during a limited period of time were included (in total 724 mothers were included). Coffee, tea or cola consumption as well as pregnancy and neonate characteristics were analysed. The mean consumption of caffeine per day slightly decreased from the first to the third trimester of pregnancy: 587 caffeine users, with a consumption of caffeine of 59.2 ± 61.5 mg/day during the first trimester as compared to 577 consumers (54.3 ± 55.4 mg/day) during the third trimester, respectively. A significant decrease of neonates' birth length was observed when mothers were using at least 100 mg/day (or two cups) of caffeine during the second and third trimesters but this difference was no longer significant after adjustment on potential confounding factors such as tobacco use. The potential existence of other confounders (e.g. poorer dietary habits or other lifestyle variables) that might also be associated with reduced birth length, may not be excluded. Caffeine use during pregnancy was associated with reduced birth length but this effect was no longer significant after adjustment on potential confounding variables.

PURPOSES: Drug induced acute liver injury (ALI) is a frequent cause of liver failure. Case-based designs were empirically assessed and calibrated in the French National claims database (SNDS), aiming to identify the optimum design for drug safety alert generation associated with ALI. METHODS: All cases of ALI were extracted from SNDS (2009-2014) using specific and sensitive definitions. Positive and negative drug controls were used to compare 196 self-controlled case series (SCCS), case-control (CC), and case-population (CP) design variants, using area under the receiver operating curve (AUC), mean square error (MSE) and coverage probability. Parameters that had major impacts on results were identified through logistic regression. RESULTS: Using a specific ALI definition, AUCs ranged from 0.78 to 0.94, 0.64 to 0.92 and 0.48 to 0.85, for SCCS, CC and CP, respectively. MSE ranged from 0.12 to 0.40, 0.22 to 0.39 and 1.03 to 5.29, respectively. Variants adjusting for multiple drug use had higher coverage probabilities. Univariate regressions showed that high AUCs were achieved with SCCS using exposed time as the risk window. The top SCCS variant yielded an AUC = 0.93 and MSE = 0.22 and coverage = 86%, with 1/7 negative and 13/18 positive controls presenting significant estimates. CONCLUSIONS: SCCS adjusting for multiple drugs and using exposed time as the risk window performed best in generating ALI-related drug safety alert and providing estimates of the magnitude of the risk. This approach may be useful for ad-hoc pharmacoepidemiology studies to support regulatory actions.

PURPOSE: This post-authorisation safety study estimated the risk of anaphylaxis in patients receiving intravenous (IV) iron in Europe, with interest in iron dextran and iron non-dextrans. Studies conducted in the United States have reported risk of anaphylaxis to IV iron ranging from 2.0 to 6.8 per 10 000 first treatments. METHODS: Cohort study of IV iron new users, captured mostly through pharmacy ambulatory dispensing, from populations covered by health and administrative data sources in five European countries from 1999 to 2017. Anaphylaxis events were identified through an algorithm that used parenteral penicillin as a positive control. RESULTS: A total of 304 210 patients with a first IV iron treatment (6367 iron dextran), among whom 13-16 anaphylaxis cases were identified and reported as a range to comply with data protection regulations. The pooled unadjusted incidence proportion (IP) ranged from 0.4 (95% confidence interval [CI], 0.2-0.9) to 0.5 (95% CI, 0.3-1.0) per 10 000 first treatments. No events were identified at first dextran treatments. There were 231 294 first penicillin treatments with 30 potential cases of anaphylaxis (IP = 1.2; 95% CI, 0.8-1.7 per 10 000 treatments). CONCLUSION: We found an IP of anaphylaxis from 0.4 to 0.5 per 10 000 first IV iron treatments. The study captured only a fraction of IV iron treatments administered in hospitals, where most first treatments are likely to happen. Due to this limitation, the study could not exclude a differential risk of anaphylaxis between iron dextran and iron non-dextrans. The IP of anaphylaxis in users of penicillin was consistent with incidences reported in the literature.

OBJECTIVE: The present observational cohort study documented the safety of agomelatine in current medical practice in out-patients suffering from major depressive disorder. METHOD: The 6-month evolution of agomelatine-treated patients was assessed with a focus on safety (emergent adverse events, liver acceptability), severity of depression using the Clinical Global Impression Severity (CGI-S) score, and functioning measured by the Sheehan Disability Scale (SDS). RESULTS: A total of 8453 depressed patients from 761 centres in 6 countries were analysed (female: 67.7%; mean age: 49.1 ± 14.8 years). Adverse events reported were in accordance with the known safety profile of agomelatine. Cutaneous events were reported in 1.7% of the patients and increased hepatic transaminases values were reported in 0.9 % of the patients. The incidence of events related to suicide/self-injury was 1.0%. Two completed suicides, not related to the study drug, were reported. CGI-S total scores and SDS sub-scores improved and numbers of days lost or underproductive decreased over the treatment period. CONCLUSIONS: In standard medical practice, agomelatine treatment was associated with a low incidence of side effects. No unexpected events were reported. A decrease in the severity of the depressive episode and improved functioning were observed. TRIAL REGISTRATION NAME: Observational cohort study to evaluate the safety of agomelatine in standard medical practice in depressed patients. A prospective, observational (non-interventional), international, multicentre cohort study. TRIAL REGISTRATION NUMBER: ISRCTN53570733.

PURPOSE: Upper gastrointestinal bleeding (UGIB) is a severe and frequent drug-related event. In order to enable efficient drug safety alert generation in the French National Healthcare System database (SNDS), we assessed and calibrated empirically case-based designs to identify drug associated with UGIB risk. METHODS: All cases of UGIB were extracted from SNDS (2009-2014) using two definitions. Positive and negative drug controls were used to compare 196 self-controlled case series (SCCS), case-control (CC) and case-population (CP) design variants. Each variant was evaluated in a 1/10th population sample using area under the receiver operating curve (AUC) and mean square error (MSE). Parameters that had major impacts on results were identified through logistic regression. Optimal designs were replicated in the unsampled population. RESULTS: Using a specific UGIB definition, AUCs ranged from 0.64 to 0.80, 0.44 to 0.61 and 0.50 to 0.67, for SCCS, CC and CP, respectively. MSE ranged from 0.07 to 0.39, 0.83 to 1.33 and 1.96 to 4.6, respectively. Univariate regressions showed that high AUCs were achieved with SCCS with multiple drug adjustment and a 30-day risk window starting at exposure. The top-performing SCCS variant in the unsampled population yielded an AUC = 0.84 and MSE = 0.14, with 10/36 negative controls presenting significant estimates. CONCLUSIONS: SCCS adjusting for multiple drugs and using a 30-day risk window has the potential to generate UGIB-related alerts in the SNDS and hypotheses on its potential population impact. Negative control implementation highlighted that low systematic error was generated but that protopathic bias and confounding by indication remained unaddressed issues.

OBJECTIVES: To introduce the methodology of the ALCAPONE project. BACKGROUND: The French National Healthcare System Database (SNDS), covering 99% of the French population, provides a potentially valuable opportunity for drug safety alert generation. ALCAPONE aimed to assess empirically in the SNDS case-based designs for alert generation related to four health outcomes of interest. METHODS: ALCAPONE used a reference set adapted from observational medical outcomes partnership (OMOP) and Exploring and Understanding Adverse Drug Reactions (EU-ADR) project, with four outcomes-acute liver injury (ALI), myocardial infarction (MI), acute kidney injury (AKI), and upper gastrointestinal bleeding (UGIB)-and positive and negative drug controls. ALCAPONE consisted of four main phases: (1) data preparation to fit the OMOP Common Data Model and select the drug controls; (2) detection of the selected controls via three case-based designs: case-population, case-control, and self-controlled case series, including design variants (varying risk window, adjustment strategy, etc.); (3) comparison of design variant performance (area under the ROC curve, mean square error, etc.); and (4) selection of the optimal design variants and their calibration for each outcome. RESULTS: Over 2009-2014, 5225 cases of ALI, 354 109 MI, 12 633 AKI, and 156 057 UGIB were identified using specific definitions. The number of detectable drugs ranged from 61 for MI to 25 for ALI. Design variants generated more than 50 000 points estimates. Results by outcome will be published in forthcoming papers. CONCLUSIONS: ALCAPONE has shown the interest of the empirical assessment of pharmacoepidemiological approaches for drug safety alert generation and may encourage other researchers to do the same in other databases.

BACKGROUND: Venous thromboembolism (VTE) after total knee or hip replacement (TKR, THR) is usually prevented with low-molecular weight heparin (LMWH), and increasingly by direct oral anticoagulants (DOAC). The aim of the present study was to compare the benefit-risk and medical costs of DOAC vs. LMWH in a real-life setting. METHODS: All patients with THR or TKR in France between Jan-1st 2013 and Sep-30th 2014, discharged to home, were identified and followed-up for 3 months in the French nationwide claims database, SNDS. DOAC users were 1:1 matched with LWMH users on gender, age and propensity score. Relative risks (RR) of hospitalized VTE, hospitalized bleeding and death were estimated using quasi-Poisson models. Medical costs were calculated according to the societal perspective, including total cost for outpatient claims and national DRG costs for hospitalisations. RESULTS: Most DOAC users (≥ 98.8%) were matched to a LMWH patient. For the 63,238 matched THR patients, the 3-month absolute risk of VTE was 0.9 with DOAC and 2.5 with LMWH (RR = 0.35 [0.23 to 0.54]), of bleeding 1.8 and 2.1 (0.88 [0.62-1.25]), death 0.7 and 1.1 (0.68 [0.40-1.15]). For the 31,440 matched TKR patients, risks were 1.6 and 2.3 (0.69 [0.42-1.16]) for VTE, 2.4 and 3.8 (0.64 [0.43 to 0.97]) for bleeding, and 0.6 and 0.8 (0.69 [0.30-1.62]) for all-cause death. Mean medical costs were 28% and 21% lower with DOAC than LMWH for THR and TKR, respectively. This nationwide study found a very low risk of VTE, hospitalized bleeding and death after THR or TKR discharge in patients with VTE prevention in real-life setting, with better benefit-risk profiles of DOAC compared to LMWH, and associated cost savings.

AIMS: We compared the 1-year safety and effectiveness of dabigatran 110 mg (D110) or 150 mg (D150) twice daily to vitamin K antagonists (VKA) in patients with nonvalvular atrial fibrillation. METHODS: New user cohort study of patients dispensed D110 or D150 vs. VKA in 2013 for nonvalvular atrial fibrillation, followed 1 year in the French Système National des Données de Santé (66 million persons). D110 and D150 users were matched 1:1 with VKA users on sex, age, date of first drug dispensing and high-dimensional propensity score. Hazard ratios [HR (95% confidence intervals)] for stroke and systemic embolism (SSE), major bleeding (MB) and death were computed using Cox proportional hazards or Fine and Gray models during exposure. RESULTS: In 14 442 matched D110 and VKA patients, mean age 79, 49% male, 91% with CHA2 DS2 -VASc ≥2 and 8% with HAS-BLED score >3, incidence rates of SSE were 1.9% and 2.6% person-years [HR 0.69 (0.56-0.84)], MB 1.8% and 2.9% [0.62 (0.51-0.76)], death 7.2% and 8.6% [0.84 (0.76-0.94)]. In 8389 matched D150 and VKA patients, mean age 67, 67% male, 65% with CHA2 DS2 -VASC ≥2; < 5% HAS-BLED >3, incidence rates were for SSE 1.4% and 1.9% [0.76 (0.56-1.04)], MB 0.6% and 1.9% [0.30 (0.20-0.46)], death 1.6% and 3.6% [0.46 (0.35-0.59)]. Numbers needed to treat to observe one fewer death were 78 for D110, 88 for D150. CONCLUSION: In real life D110 and D150 were at least as effective, and safer than VKA.

Tobacco and/or alcohol use during pregnancy is a major public health concern. The aim of our study was to identify risk factors associated to maternal alcohol and tobacco use assessed by maternal self-reports combined with biological measurements in meconium samples of cotinine and ethylglucuronide which reflect fetal exposure to tobacco and alcohol, respectively, during the 3rd trimester of pregnancy. We conducted a prospective study in three maternity hospitals in a large urban area during consecutive weeks (2010 and 2011). Maternal sociodemographic and clinical characteristics were assessed after delivery, using the French version of the Addiction Severity Index. Cotinine and ethylglucuronide were measured in meconium samples. Seven hundred and twenty-four women were included, and 645 meconium samples collected. Using multivariate analyses, we found that not being married or having a smoking partner predicts maternal tobacco use. In contrast, a decreased risk was associated with higher education level and wanted pregnancy. The risk for alcohol use increased when the mother had been in conflict with any relative or her partner for a long time throughout her life, as well as in case of previous treatment for any mental or emotional disorder. Using multivariate analyses and cotinine presence in meconium samples, the risks were similar except for marital status, which was not associated to cotinine presence. Community education and prevention programs should urgently be improved for all women of childbearing age with a special focus on those with past histories of mental or emotional disorders and addictive disorders. Smoking cessation should be recommended to both parents.

OBJECTIVE: The aim of this study was to evaluate the efficacy of intrasphincteric injections of autologous myoblasts (AMs) in fecal incontinence (FI) in a controlled study. SUMMARY OF BACKGROUND DATA: Adult stem cell therapy is expected to definitively cure FI by regenerating damaged sphincter. Preclinical data and results of open-label trials suggest that myoblast therapy may represent a noninvasive treatment option. METHODS: We conducted a phase 2 randomized, double-blind, placebo-controlled study of intrasphincteric injections of AM in 24 patients. The study compared outcome after AM (n = 12) or placebo (n = 12) injection using Cleveland Clinic Incontinence (CCI), score at 6 and 12 months. Patients in the placebo group were eligible to receive frozen AM after 1 year. RESULTS: At 6 months, the median CCI score significantly decreased from baseline in both the AM (9 vs 15, P = 0.02) and placebo (10 vs 15, P = 0.01) groups. Hence, no significant difference was found between the 2 groups (primary endpoint) at 6 months. At 12 months, the median CCI score continued to ameliorate in the AM group (6.5 vs 15, P = 0.006), while effect was lost in the placebo group (14 vs 15, P = 0.35). Consequently, there was a higher response rate at 12 months in the treated than the placebo arm (58% vs 8%, P = 0.03). After delayed frozen AM injection in the placebo group, the response rate was 60% (6/10) at 12 months. CONCLUSIONS: Intrasphincteric AM injections in FI patients have shown tolerance, safety, and clinical benefit at 12 months despite a transient placebo effect at 6 months.

BACKGROUND: High doses of corticosteroids are considered the standard treatment for pemphigus. Because long-term corticosteroid treatment can cause severe and even life-threatening side-effects in patients with this disease, we assessed whether first-line use of rituximab as adjuvant therapy could improve the proportion of patients achieving complete remission off-therapy, compared with corticosteroid treatment alone, while decreasing treatment side-effects of corticosteroids. METHODS: We did a prospective, multicentre, parallel-group, open-label, randomised trial in 25 dermatology hospital departments in France (Ritux 3). Eligible participants were patients with newly diagnosed pemphigus aged 18-80 years being treated for the first time (not at the time of a relapse). We randomly assigned participants (1:1) to receive either oral prednisone alone, 1·0 or 1·5 mg/kg per day tapered over 12 or 18 months (prednisone alone group), or 1000 mg of intravenous rituximab on days 0 and 14, and 500 mg at months 12 and 18, combined with a short-term prednisone regimen, 0·5 or 1·0 mg/kg per day tapered over 3 or 6 months (rituximab plus short-term prednisone group). Follow-up was for 3 years (study visits were scheduled weekly during the first month of the study, then monthly until month 24, then an additional visit at month 36). Treatment was assigned through central computer-generated randomisation, with stratification according to disease-severity (severe or moderate, based on Harman's criteria). The primary endpoint was the proportion of patients who achieved complete remission off-therapy at month 24 (intention-to-treat analysis). This study is registered with ClinicalTrials.gov, number NCT00784589. FINDINGS: Between May 10, 2010, and Dec 7, 2012, we enrolled 91 patients and randomly assigned 90 to treatment (90 were analysed; 1 patient withdrew consent before the random assignment). At month 24, 41 (89%) of 46 patients assigned to rituximab plus short-term prednisone were in complete remission off-therapy versus 15 (34%) of 44 assigned to prednisone alone (absolute difference 55 percentage points, 95% CI 38·4-71·7; p<0·0001. This difference corresponded to a relative risk of success of 2·61 (95% CI 1·71-3·99, p<0·0001), corresponding to 1·82 patients (95% CI 1·39-2·60) who would need to be treated with rituximab plus prednisone (rather than prednisone alone) for one additional success. No patient died during the study. More severe adverse events of grade 3-4 were reported in the prednisone-alone group (53 events in 29 patients; mean 1·20 [SD 1·25]) than in the rituximab plus prednisone group (27 events in 16 patients; mean 0·59 [1·15]; p=0·0021). The most common of these events in both groups were diabetes and endocrine disorder (11 [21%] with prednisone alone vs six [22%] with rituximab plus prednisone), myopathy (ten [19%] vs three [11%]), and bone disorders (five [9%] vs five [19%]). INTERPRETATION: Data from our trial suggest that first-line use of rituximab plus short-term prednisone for patients with pemphigus is more effective than using prednisone alone, with fewer adverse events.

We conducted a prospective study to assess the prognostic impact of selected copy number variations (CNVs) in Stage II-III microsatellite stable (MSS) colon cancer. A total of 401 patients were included from 01/2004 to 01/2009. The CNVs in 8 selected target genes, DCC/18q, EGFR/7p, TP53/17p, BLK/8p, MYC/8q, APC/5q, ERBB2/17q and STK6/20q, were detected using a quantitative multiplex polymerase chain reaction of short fluorescent fragment (QMPSF) method. The primary end-point was the impact of the CNVs on the 4-year disease-free survival (DFS). The recurrence rate at 4 years was 20.9%, corresponding to 14% Stage II patients versus 31% Stage III patients (p < 0.0001). The 4-year DFS was significantly decreased in patients with a loss at DCC/18q (p = 0.012) and a gain at ERBB2/17q (p = 0.041). The multivariate analysis demonstrated that Stage III, a loss at DCC/18q and a gain at ERBB2/17q were independent factors associated with DFS. A combination of DCC/18q and ERBB2/17q was also associated with relapse, with the hazard ratio increasing from 1 to 2.4 (95% confidence interval (CI), 1.5-4.1) and 3.1 (95% CI, 1.2-8.4) in the presence of 0, 1 or 2 alterations, respectively (p = 0.0013). CNVs in DCC/18q and ERBB2/17q are significantly associated with DFS in Stage II-III MSS colon cancer.
