RESUMO

OBJECTIVES: To explore the 10-year tolerability profile of glucocorticoids (GC) use in patients with early RA. METHODS: Analysis of 10-year outcome from the early arthritis ESPOIR cohort. Patients were stratified in two groups, without or with GC treatment at least once during their follow-up. The primary outcome was a composite of deaths, cardiovascular diseases (CVD), severe infections and fractures. The weighted Cox time-dependent analysis model was used with inverse probability of treatment weighting (IPTW) propensity score method. RESULTS: Among the 608 patients [480 women, mean age of 47.5 (12.1) years], 397 (65%) received low-dose GC [median 1.9 mg/day (IQR 0.6-4.2), mean cumulative prednisone dose 8468 mg (8376), mean duration 44.6 months (40.1)]. In univariate analysis, over 95 total events (10 deaths, 18 CVDs, 32 fractures and 35 severe infections), patients taking GC experienced more events (n = 71) than those without GC (n = 24) (P =0.035). Highest cumulative exposure of GC (≥8.4 g) was associated with highest risk of occurrence of the primary outcome (24.3%, P =0.007), CVDs (7.9%, P =0.001) and severe infections (9.9%, P =0.024). The risk of events over time was significantly associated with GC, age, hypertension and ESR. The risk associated with GC treatment increased between the first follow-up visit [hazard ratio (HR) at 1 year = 0.46, 95% CI: 0.23, 0.90] and 10 years (HR = 6.83, 95% CI: 2.29, 20.35). CONCLUSION: The 10-year analysis of this prospective early RA cohort supports a dose and time-dependent impact of low-dose GC treatment, with a long-term high risk of severe outcomes.

RESUMO

OBJECTIVE: To report the 10-year outcome of an inception cohort of patients with early rheumatoid arthritis (RA), the ESPOIR cohort, and predictors of outcome. METHODS: From 2003 to 2005, 813 patients were included if they had early arthritis (<6 months) with a high probability of RA and had never been prescribed DMARDs. Multivariate analysis was used to evaluate predictors of outcome. RESULTS: In total, 521 (64.1%) RA patients were followed up for 10 years; 35 (4.3%) died, which appears to be similar to the French general population. Overall, 480 (92.1%) patients received a DMARD; 174 (33.4%) received at least one biologic DMARD, 13.6% within 2 years. At year 10, 273 (52.4%) patients were in DAS28 remission, 40.1% in sustained remission, 14.1% in drug-free remission, 39.7% in CDAI remission. Half of the patients achieved a health assessment questionnaire-disability index (HAQ-DI) < 0.5. SF-36 physical component and pain were well controlled. Structural progression was weak, with a mean change from baseline in modified Sharp score of 11.0 (17.9). Only 34 (6.5%) patients required major joint surgery. A substantial number of patients showed new comorbidities over 10 years. Positivity for anti-citrullinated peptides antibodies (ACPA) was confirmed as a robust predictor of long-term outcome. CONCLUSIONS: We report a very mild 10-year outcome of a large cohort of patients with early RA diagnosed in the early 2000s, which was much better than results for a previous cohort of patients who were recruited in 1993. This current favourable outcome may be related to more intensive care for real-life patients.

RESUMO

In France, cervical cancer screening based on cervical smear has a participation rate of around 60%. New screening strategies are encouraged to increase the participation of under-screened women, including vaginal self-sampling with high-risk human papillomavirus (HR-HPV) testing. This study was based on the distribution of an anonymous self-administered questionnaire to assess the acceptability of vaginal self-sampling with HR-HPV testing by women aged 25 to 65 years in two French Departments of the South of France, Aude, and Hérault, showing low participation in cervical cancer screening. Factors influencing this acceptability were also analyzed. From May to July 2017, 349 completed questionnaires were collected. Women declared high acceptability for vaginal self-sampling (81%) preferably at home (82.6%). Acceptability was statistically higher in the Department of Herault (p = .001) and for women older than 50 years (p = .018). There was no difference according to educational level or attendance to cervical cancer screening. Knowledge about cervical cancer and cervical cancer screening was significantly influenced by educational level. This study confirmed that vaginal self-sampling with HR-HPV testing was highly accepted, including by under-screened women, encouraging further interventional studies. Education about cervical cancer and cervical cancer screening should be part of these programs, especially for women with lower educational level.

RESUMO

BACKGROUND: Flap surgery for deep pelvic pressure ulcers has already shown its effectiveness. Most studies relating to the postoperative period assessed complications rates and associated risk factors, but none focused on delayed wound healing. The objective of this study was to describe wound healing delay after primary flap surgery in patients with spinal cord injury (SCI) and to assess associated risk factors. METHODS: This observational retrospective study based on medical charts included all persons with SCI operated for primary flap surgery for pelvic PU in the Hérault department of France between 2006 and 2014. Overall, 100 biomedical, psychological, socioeconomics and care management factors were studied. The primary outcome was wound healing delay, defined as time from surgery to complete cutaneous closure. RESULTS: 85 patients were included. Median healing time was 48 days (R: 20-406). Healing rate was 70% at 3 months and 90% at 4 months. After a multivariate analysis three factors were significantly associated with delayed wound healing: duration of hospitalization in the acute care unit (HR = 2.68; p = 0.004), local post-operative complication (HR = 10.75; p = 0.02), and post-operative sepsis (HR = 2.18; p = 0.02). CONCLUSION: After primary skin flap surgery for PU in persons with SCI, delayed wound healing is related to local or general complications as well as care management organization. The risk of delayed wound healing justifies the implementation of a coordinated pre-operative management to prevent complications and a structured care network for an earlier transfer to a SCI rehabilitation center.

RESUMO

PURPOSE: to present our experience in the management of pathological nipple discharge using the procedure D.DL.DB: "ductoscopy" (D) coupled to "duct lavage" (DL) plus "duct brushing" (DB) for etiologic diagnosis. Also to compare the diagnosis obtained with D.DL.DB to the final histology. MATERIAL AND METHOD: Eighty-five patients with organic unilateral nipple discharge were enrolled in two Breast Units. 82 of 85 patients were investigated successfully with D.DL.DB. Results:: The final histological results were: papilloma 46.3%, duct ectasia 36.5%, breast cancer 8.5%, precancer lesions 4.9%, and mixed benign lesions 3.8%. Pyramidectomy and radical ductectomy were performed in 76 and 6 cases respectively. In 80% of the cases, DLDB cytology results were identical to the final histology. (Kappa=0;69 CI=[0.56 -0.82]. The sensitivity of D.DL.DB versus pathology, for cancer or precancer lesions was 81.8% (CI=0.59 -1) and the specificity was 97.1% (CI=0.93 -1). Using Koch scale, the concordance between the two methods D.DL.DB and surgery was high and the sensitivity was in the upper range regarding the literature (58% to 90%). CONCLUSION: Our experience confirms the high value of D.DL.DB in the management of organic nipple discharge.

RESUMO

BACKGROUND: This prospective multicenter study evaluated the prognostic value of circulating tumor cells (CTCs) in relapsing nonoperable or metastatic head and neck squamous cell carcinoma (rHNSCC) treated by chemotherapy and cetuximab. METHODS: In 65 patients suitable for analyses, peripheral blood was taken at day 0 (D0) D7, and D21 of treatment for CTC detection by CellSearch®, EPISPOT, and flow cytometry (FCM). Progression-free survival (PFS) was assessed with the Kaplan-Meier method and compared with the log-rank test (P < 0.05). RESULTS: At D0, CTCs were detected with EPISPOT, CellSearch, and FCM in 69% (45/65), 21% (12/58), and 11% (7/61) of patients, respectively. In the patients tested with all 3 methods, EPISPOT identified 92% (36/39), 92% (35/38), and 90% (25/28) of all positive samples at D0, D7, and D21, respectively. Median PFS time was significantly lower in (a) patients with increasing or stable CTC counts (36/54) from D0 to D7 with EPISPOTEGFR (3.9 vs 6.2 months; 95% CI, 5.0-6.9; P = 0.0103) and (b) patients with ≥1 CTC detected with EPISPOT or CellSearch® (37/51) (P = 0.0311), EPISPOT or FCM (38/54) (P = 0.0480), and CellSearch or FCM (11/51) (P = 0.0005) at D7. CONCLUSIONS: CTCs can be detected before and during chemotherapy in patients with rHNSCC. D0-D7 CTC kinetics evaluated with EPISPOTEGFR are associated with the response to treatment. This study indicates that CTCs can be used as a real-time liquid biopsy to monitor the early response to chemotherapy in rHNSCC. CLINICALTRIALSGOV IDENTIFIER: NCT02119559.

RESUMO

BACKGROUND: Gram-positive organisms are a leading cause of infection in cardiovascular surgery. Furthermore, these patients have a high risk of developing postoperative renal failure in intensive care unit (ICU). Some antibiotic drugs are known to impair renal function. The aim of the study was to evaluate whether patients treated for Gram-positive cardiovascular infection with daptomycin (DAP) experienced a lower incidence of acute kidney injury (AKI) when compared to patients treated with vancomycin (VAN), with comparable efficacy. METHODS: ICU patients who received either DAP or VAN, prior to or after cardiovascular surgery or mechanical circulatory support, from January 2010 to December 2012, were included in this observational retrospective cohort study. We excluded patients with end stage renal disease and antibiotic prophylaxis. The primary endpoint was the incidence of AKI within the first week of treatment. Secondary endpoints were the incidence of AKI within the first 14 days of treatment, the severity of AKI including renal replacement therapy (RRT), the rates of clinical failure (unsuccessful infection treatment) and of premature discontinuation and mortality. To minimize selection bias, we used a propensity score to compare the 2 groups. Univariate and multivariate analysis were performed to determine factors associated with AKI. RESULTS: Seventy two patients, treated for infective endocarditis, cardiovascular foreign body infection, or surgical site infection were included (DAP, n = 28 and VAN, n = 44). AKI at day 7 was observed in 28 (64%) versus 6 (21%) of the VAN and DAP patients, respectively (p = 0.001). In the multivariate analysis adjusted to the propensity score, vancomycin treatment was the only factor associated with AKI (Odds Ratio 4.42; 95% CI: 1.39-15.34; p = 0.014). RRT was required for 2 (7%) DAP patients and 13 (30%) VAN patients, p = 0.035. Premature discontinuation and clinical failure occurred more frequently in VAN group than in DAP group (25% versus 4%, p = 0.022 and 42% versus 12%, respectively, p = 0.027). CONCLUSIONS: Daptomycin appears to be safer than vancomycin in terms of AKI risk in ICU patients treated for cardiovascular procedure-related infection. Daptomycin could be considered as a first line treatment to prevent AKI in high-risk patients.

RESUMO

PURPOSE: While familial forms of complex disorders/differences of sex development have been widely reported, data regarding isolated hypospadias are sparse and a family history is thought to be less frequent. We aimed to determine the frequency of hypospadias in families of boys with hypospadias, to establish whether these familial forms exhibit a particular phenotype and to evaluate the prevalence of genetic defects of the main candidate genes. MATERIALS AND METHODS: A total of 395 boys with hypospadias were prospectively screened for a family history with a standardized questionnaire, extensive clinical description, family tree and sequencing of AR, SF1, SRD5A2 and MAMLD1. RESULTS: Family history of hypospadias was more frequent than expected (88 patients, 22.3%). In 17 instances (19.3%) familial hypospadias cases were multiple. Familial hypospadias was related to the paternal side in 59.1% of cases, consisting of the father himself (30.7%) as well as paternal uncles and cousins. Premature birth, assisted reproductive techniques, other congenital abnormalities and growth retardation were not more frequent in familial hypospadias than in sporadic cases. The severity of phenotype was similar in both groups. The results of genetic analysis combined with previous data on androgen receptor sequencing revealed that familial cases more frequently tend to demonstrate genetic defects than sporadic cases (5.68% vs 1.63%, p = 0.048). CONCLUSIONS: Familial forms of hypospadias are far more frequent than previously reported. Even minor and isolated forms justify a full clinical investigation of the family history. Detecting these hereditary forms may help to determine the underlying genetic defects, and may improve followup and counseling of these patients.

RESUMO

STUDY DESIGN: Cross-sectional psychometrics study. OBJECTIVES: To determine the construct validity and internal consistency of the revised Skin Management Needs Assessment Checklist (revised SMnac). SETTING: Six spinal cord rehabilitation centers. METHODS: One-hundred and thirty-two community-dwelling individuals with spinal cord injury (SCI) were included. Construct validity was assessed by a Spearman's rank correlation coefficient between the revised SMnac and several questionnaires: Rosenberg Self-Esteem Scale, Ways of Coping Questionnaire, Hospital Anxiety and Depression Scale (HADS), Braden scale; or clinical variables: educational level, presence of a pressure ulcer (PU), history of multiple PUs, time since injury, and pain. RESULTS: The study evidenced construct validity with a fair to moderate correlation coefficient between the revised SMnac and Rosenberg scale (rs = 0.25; p = 0.03), active coping (rs = 0.29; p = 0.001), HADS (rs = -0.43; p < 0.0001), and time since injury (rs = 0.49; p < 0.0001). The presence of PU and history of multiple PUs were strongly correlated with the revised SMnac score (respectively, p = 0.01 and 0.001). Internal consistency was excellent (α = 0.907). CONCLUSION: These results show that the revised SMnac is a valid tool to assess PU self-management in individuals with SCI. Further studies are needed to assess the revised SMnac's responsiveness to change.

RESUMO

OBJECTIVE: To explore the 7-year tolerability profile of glucocorticoids (GC) for early rheumatoid arthritis (RA). METHODS: We examined data for 602 patients with RA from the early arthritis Etude et Suivi des POlyarthrites Indifférenciées Récentes (ESPOIR) cohort (<6 months disease duration) stratified into two groups: with or without GC treatment at least once during follow-up (median 7 years (IQR 0.038-7.65)). The main outcome was a composite of death, cardiovascular disease (including myocardial ischaemia, cerebrovascular accident and heart failure), severe infection and fracture. RESULTS: Among the 602 patients with RA (476 women (79%), mean age 48±12 years), 386 with GC (64.1%) received low-dose prednisone (mean 3.1±2.9 mg/day for the entire follow-up): 263 started GC during the first 6 months (68%), and the mean duration of total GC treatment was 1057±876 days. As compared with patients without GC (216 (35.9%)), those with GC showed greater use of non-steroidal anti-inflammatory drugs, synthetic and biological disease-modifying antirheumatic drugs and had more active disease disability, higher C reactive protein and anticitrullinated protein antibody levels. Among 65 events (7 deaths, 14 cardiovascular diseases, 19 severe infections and 25 fractures), 44 and 21 occurred in patients with and without GC (p=0.520). Infections were more frequent, although not significantly, in patients with than without GC (p=0.09). On weighted Cox proportional-hazards analysis, with use of propensity score and inverse-probability-of-treatment weighting, and including age, gender, history of hypertension and GC treatment, outcomes did not differ with and without GC (p=0.520; HR=0.889; 95% CI 0.620 to 1.273). CONCLUSIONS: This 7-year analysis of the ESPOIR cohort supports the good safety profile of very low-dose GC for early active RA.

RESUMO

BACKGROUND: Acute-on-chronic liver failure (ACLF) is associated with a significant short-term mortality rate (23%-74%), depending on the number of organ failures. Some patients present with ACLF at the time of liver transplantation (LT). The aim of this study was to assess whether ACLF was also a prognostic factor after LT and, if applicable, to construct a score that could predict 90-day mortality. METHODS: Three hundred and fifty cirrhotic patients, who underwent LT between January 2008 and December 2013, were enrolled. We used ACLF grades according to EASL-CLIF consortium criteria to categorize the cirrhotic patients. A propensity score was applied with an Inverse Probability Treatment Weighting in a Cox model. A predictive score of early mortality after LT was generated. RESULTS: One hundred and forty patients (40%) met the criteria for ACLF. The overall mortality rate at 90 days post-transplant was 10.6% (37/350 patients). ACLF at the time of LT (HR: 5.78 [3.42-9.77], P<.001) was an independent predictor of 90-day mortality. Infection occurring during the month before LT, high recipient age and male recipient, the reason for LT and a female donor were also independent risk factors for early mortality. Using these factors, we have proposed a model to predict 90-day mortality after LT. CONCLUSIONS: LT is feasible in cirrhotic patients with ACLF. However, we have shown that ACLF is a significant and independent predictor of 90-day mortality. We propose a score that can identify candidate cirrhotic patients in whom LT might be associated with futile LT.

RESUMO

BACKGROUND & AIMS: A major limitation to liver transplantation is organ shortage leading to the use of non-optimal liver grafts. The Donor Risk Index has been validated and recommended to select donors/organs. The Eurotransplant Donor Risk Index was derived from the Donor Risk Index. The objective of our study was to perform an external validation of both Donor Risk Index and Eurotransplant-Donor Risk Index against the French liver transplantation Cristal registry according to recommendations of the Transparent Reporting of a multivariable prediction model for Individual Prognosis Or Diagnosis. METHODS: Liver transplantations performed in France between 2009 and 2013 were used to perform the validation study for the Donor Risk Index and the Eurotransplant-Donor Risk Index respectively. We applied on the French data the models used to construct the Donor Risk Index and the Eurotransplant-Donor Risk Index respectively. RESULTS: Neither the Donor Risk Index nor the Eurotransplant-Donor Risk Index were validated against this dataset. Discrimination and calibration of these scores were not preserved according to our data. Important donor and candidates differences between our dataset and the Organ Procurement and Transplantation Network or the Eurotransplant datasets may explain why the Donor Risk Index and the Eurotransplant-Donor Risk Index appeared unadapted to the French transplant registry. CONCLUSION: Neither of these risk indexes were suitable to optimize the French liver allocation system. Thus, our next step will be to propose a general adaptive model for a Donor Risk Index.

RESUMO

OBJECTIVES: To evaluate the outcomes of hypospadias surgery according to age and to determine if some complications are age-related. PATIENTS AND METHODS: This retrospective study was based on 722 boys with hypospadias undergoing primary repair. A total of 501 boys underwent urethroplasty and were included in the study. Complications requiring an additional procedure (stenosis, fistula, dehiscence, relapse of curvature, urethrocele) were included in the analysis, as well as healing problems, infections, haematomas and detrusor-sphincter dyssynergy. Logistic regression analysis was performed. RESULTS: Hypospadias was anterior in 63.1%, mid-penile in 20.5%, posterior in 8.4% and scrotal in 7.9% of the boys. The median (range) age was 4 (1-16) years. The overall rates of re-intervention and complications were 22.8% and 36.2%, respectively. Age >2 years was a significant predictor of complications (P = 0.002, odds ratio 1.98 [95% confidence interval 1.26-3.13]). Some periods of time appeared to be associated with a specific complication: dyssynergy was more common between the ages of 24 and 36 months (12.5 vs 3.6%; P = 0.01) and healing problems were more common in boys aged >13 years (1.5 vs 28.5%; P = 0.06). CONCLUSION: Delayed surgery may be detrimental for patients. Factors related to age may influence the rate of complications. After the age of 2 years, urethral surgery may interfere with the normal toilet-training process. During puberty, endogenous testosterone may alter healing. Even if no specific data exist for severe hypospadias, it may be prudent to continue to advocate early surgery in patients with disorders of sex development.

RESUMO

BACKGROUND: Information and theory beyond copula concepts are essential to understand the dependence relationship between several marginal covariates distributions. In a therapeutic trial data scheme, most of the time, censoring occurs. That could lead to a biased interpretation of the dependence relationship between marginal distributions. Furthermore, it could result in a biased inference of the joint probability distribution function. A particular case is the cost-effectiveness analysis (CEA), which has shown its utility in many medico-economic studies and where censoring often occurs. METHODS: This paper discusses a copula-based modeling of the joint density and an estimation method of the costs, and quality adjusted life years (QALY) in a cost-effectiveness analysis in case of censoring. This method is not based on any linearity assumption on the inferred variables, but on a punctual estimation obtained from the marginal distributions together with their dependence link. RESULTS: Our results show that the proposed methodology keeps only the bias resulting statistical inference and don't have anymore a bias based on a unverified linearity assumption. An acupuncture study for chronic headache in primary care was used to show the applicability of the method and the obtained ICER keeps in the confidence interval of the standard regression methodology. CONCLUSION: For the cost-effectiveness literature, such a technique without any linearity assumption is a progress since it does not need the specification of a global linear regression model. Hence, the estimation of the a marginal distributions for each therapeutic arm, the concordance measures between these populations and the right copulas families is now sufficient to process to the whole CEA.

RESUMO

BACKGROUND: Double-adjustment can be used to remove confounding if imbalance exists after propensity score (PS) matching. However, it is not always possible to include all covariates in adjustment. We aimed to find the optimal imbalance threshold for entering covariates into regression. METHODS: We conducted a series of Monte Carlo simulations on virtual populations of 5,000 subjects. We performed PS 1:1 nearest-neighbor matching on each sample. We calculated standardized mean differences across groups to detect any remaining imbalance in the matched samples. We examined 25 thresholds (from 0.01 to 0.25, stepwise 0.01) for considering residual imbalance. The treatment effect was estimated using logistic regression that contained only those covariates considered to be unbalanced by these thresholds. RESULTS: We showed that regression adjustment could dramatically remove residual confounding bias when it included all of the covariates with a standardized difference greater than 0.10. The additional benefit was negligible when we also adjusted for covariates with less imbalance. We found that the mean squared error of the estimates was minimized under the same conditions. CONCLUSION: If covariate balance is not achieved, we recommend reiterating PS modeling until standardized differences below 0.10 are achieved on most covariates. In case of remaining imbalance, a double adjustment might be worth considering.

RESUMO

OBJECTIVE: As covariates are not always adequately balanced after propensity score matching and double- adjustment can be used to remove residual confounding, we compared the performance of several double-robust estimators in different scenarios. METHODS: We conducted a series of Monte Carlo simulations on virtual observational studies. After estimating the propensity scores by logistic regression, we performed 1:1 optimal, nearest-neighbor, and caliper matching. We used 4 estimators on each matched sample: (1) a crude estimator without double-adjustment, (2) double-adjustment for the propensity scores, (3) double-adjustment for the unweighted unbalanced covariates, and (4) double-adjustment for the unbalanced covariates, weighted by their strength of association with the outcome. RESULTS: The crude estimator led to highest bias in all tested scenarios. Double-adjustment for the propensity scores effectively removed confounding only when the propensity score models were correctly specified. Double-adjustment for the unbalanced covariates was more robust to misspecification. Double-adjustment for the weighted unbalanced covariates outperformed the other approaches in every scenario and using any matching algorithm, as measured by the mean squared error. CONCLUSION: Double-adjustment can be used to remove residual confounding after propensity score matching. The unbalanced covariates with the strongest confounding effects should be adjusted.

RESUMO

OBJECTIVE: The aim of the study was to evaluate dynamic contrast-enhanced magnetic resonance (MR) imaging in the characterization of parotid gland tumors. METHODS: Fifty-five parotid lesions in 55 patients were retrospectively included. Two observers interpreted 2 reading protocols derived from all MR imaging in 2 distinct sessions, independently and blinded. Benign versus malignant distinction was carried out for protocol 1 (without contrast administration) and protocol 2 (with dynamic contrast-enhanced sequence). Histopathological results after surgical resection were used as the criterion standard. Diagnostic accuracy was compared between protocols using McNemar test. A P values of less than 0.05 indicated significant difference. RESULTS: There was no intraobserver statistical discordance between protocols for both observers (P = 0.27 and P = 1). Interobserver reliability showed moderate agreement for protocol 1 (κ = 0.591; 95% confidence interval [CI], 0.376-0.806) and 2 (κ = 0.463, 95% CI, 0.226-0.701). Intraobserver reliability showed moderate agreement for observer 1 (κ = 0.507; 95% CI, 0.279-0.736) and 2 (κ = 0.477; 95% CI, 0.241-0.712). CONCLUSIONS: Magnetic resonance imaging protocol including dynamic sequence for the characterization of parotid gland lesion yielded nonsignificant increases in sensitivity, specificity, or positive predictive values, and negative predictive values over noninjected protocol.

RESUMO

Medical-administrative databases are an important source of big data to assess the epidemiology of diseases and interventions, compare drugs, and investigate rare adverse events. We describe the French national health insurance system databases and the Epidemiology and Safety (EPISAFE) collaboration program in ophthalmology and illustrate the paper with recent studies that used the databases to investigate cataract surgery. The Système national d'information inter-régime de l'assurance maladie (SNIIR-AM) is one of the largest databases of medical and administrative data for a general population, covering nearly 65 million people. The SNIIR-AM database links data for all outpatient-reimbursed health expenditures, hospitalization in all 1,546 French private or public healthcare facilities, and date of death. The use of this database provides information at the scale of the entire country, allowing measurement of the impact of changes in practices and new guidelines. Between 2009 and 2012, a total of 2,717,203 eyes in 1,817,865 patients underwent cataract surgery in France, and the incidence of cataract surgery increased from 9.86 to 11.08/1,000 person-years. The 4-year cumulative risk of retinal detachment was 0.99%, and patients <60 years of age were at higher risk of retinal detachment. The incidence of pseudophakic cystoid macular edema was 0.95%. From 2005 to 2014, from data including more than 6 million procedures, the incidence of endophthalmitis after cataract surgery decreased from 0.15 to 0.05%. The EPISAFE collaboration program encompasses the key issues facing ophthalmology, including public health and public policy concerning disease incidence and prevalence, safety and adverse event monitoring, and clinical guidelines.

RESUMO

BACKGROUND: Skin-sparing mastectomy (SSM) with immediate breast reconstruction (IBR) is increasingly used in invasive breast cancer. However, adjuvant chemotherapy (CT) and radiotherapy (RT) can increase the rate of local complications. OBJECTIVE: The aim of this study was to assess the morbidity of SSM-IBR after neoadjuvant CT and RT. METHODS: A French prospective pilot study of women aged 18-75 years with invasive breast cancer requiring mastectomy after CT and RT. Reconstruction was performed using autologous latissimus dorsi flap with or without prosthesis. The primary endpoint was the skin necrosis rate within 6 months, while secondary endpoints included pathological complete response rate (pCR) and global morbidity. RESULTS: Among 94 patients included in this study, 83 were analyzed (mean age 45.2 ± 9.5 years, T1 23.6 %, T2 55.6 %, T3 18.1 %). All but one patient received anthracyclines and taxanes, and all patients received RT (49.3 ± 5.2 Gy) before SSM-IBR. Prostheses were used for IBR in 32 patients (mean volume 256 ± 73 mm(3)). Five patients had necrosis (≤2 cm(2), 2-10 cm(2) and >10 cm(2), in three, one, and one cases, respectively), and they all recovered without revision surgery. Among 50 patients who underwent upfront mastectomy, 36 % achieved pCR. CONCLUSIONS: SSM-IBR performed after CT and RT is safe, with an acceptable local morbidity rate. Long-term data are needed to evaluate recurrence rates.

RESUMO

BACKGROUND: Health inequalities have increased over the last 30 years. Our goal was to investigate the relationship between low individual socioeconomic status and poor breast cancer prognosis. Our hypothesis was: low socioeconomic status patients have a higher risk of being diagnosed with late stage breast cancer than high socioeconomic status ones due to delayed diagnosis. METHODS: We conducted a matched case-control study on 619 women with breast cancer, living in the Hérault, a French administrative area. Both Cases and Controls were recruited among invasive cases diagnosed in 2011 and 2012 and treated in Hérault care centers. Cases were defined as patients with advanced stages. Controls were composed of early stage patients. Individual socioeconomic status was assessed using a validated individual score adapted to the French population and health care system. RESULTS: We observed that low socioeconomic status patients have a 2-fold risk of having late stage breast cancer regardless of cancer characteristics and detection mode (screening vs. clinical signs). CONCLUSION: One reason explaining those results could be that low socioeconomic status patients have less regular follow-up which can lead to later and poorer diagnosis. Follow-up is improved for women with a better awareness of breast cancer. Health policy makers could reduce health inequalities by reducing the delay in breast cancer diagnosis for low socioeconomic status women.
