Incidence and risk factors of venous thromboembolism: Peculiarities in psychiatric institutions.

INTRODUCTION: The objectives of this study were to assess the incidence and risk factors for venous thromboembolism (VTE) in a population of patients hospitalized in a psychiatric setting. MATERIAL AND METHODS: Episodes of VTE occurring in patients hospitalized at the Erstein Hospital (France), specialized in psychiatry, were retrospectively identified from a computerized database. The clinical, somatic, psychiatric and therapeutic characteristics of each patient were analyzed in comparison with a control population composed of patients of similar age and sex, hospitalized during the same period in a psychiatric setting but who did not suffer from VTE. RESULTS: Between January 2012 and October 2015, 12,320 patients were hospitalized. Forty-one patients experienced an episode of VTE, giving an incidence of 47.8per1000patient-years (3.32 cases per 1000 patients). Restriction of mobility (restraint or confinement), somatic clinical profile, psychiatric diagnosis or psychotropic treatment were not associated with an increased risk of VTE. The event occurred within the first 48h of hospitalization for 31.7% of patients, and within the first week for 56.1%. Time to onset for the occurrence of VTE between admission and the end of the first week was significantly associated with acute decompensation of a chronic psychiatric pathology (p=0.003). CONCLUSION: The incidence of VTE in a psychiatric setting is high. Acute decompensation of a chronic psychiatric pathology is associated with a risk of VTE.

[Meteo-U-rology: climate impact on urological emergencies]. / Météo-U-rologie : influence du climat sur les principales urgences urologiques - étude épidémiologique.

INTRODUCTION AND OBJECTIVES: The aim of this study was to analyze the weather influence on the onset of renal colic (RC), acute urinary retention (AUR) and testicular torsion (TT). MATERIALS AND METHODS: We correlated the daily number of RC, AUR and TT cases admitted to our urology department and weather conditions between 2005 and 2009 on day-to-day basis. Eight hundred and seventy-six RC, 453 AUR and 50 TT were analyzed. Information on temperature, atmospheric pressure, relative humidity, vapor pressure, wind force, evapotranspiration and sunshine level were collected from the national meteorological office (Meteo-France) in Besançon, France. We performed a univariate and a multivariate Stepwise method in linear regression using Akaike Information Criterion. RESULTS: We reported a statistically significant increased risk of renal colic at higher vapor pressure. Likewise, temperature seemed to be a risk factor for occurrence of renal colics. We determined an increased daily rate when maximal daily temperature rises above 20 Celsius degrees (P = 0.05). Furthermore, we observed a positive link between mean (P = 0.05) and minimal (P = 0.08) daily temperature and urolithiasis. Contrarywise AUR was more frequent when the mean temperature falls below zero Celsius degree. We also demonstrated a non-significant influence of temperature on TT, with 3 fold higher events during cold period. Much more mystic, we noted a higher AUR rate on new moon days, and fewer renal colic on full moon. CONCLUSIONS: Further investigations are necessary to understand the mechanisms underlying the relationship between urologic diseases and climate. But our findings could help us justify healthy living messages.

Neoadjuvant therapy for breast cancer has no benefits on overall survival or on the mastectomy rate in routine clinical practice. A population-based study with a median follow-up of 11 years using propensity score matching.

BACKGROUND: Even though neoadjuvant chemotherapy has shown no benefits on overall survival (OS), it is being widely used in the treatment of breast cancer. This is based on the assumption that it may diminish the mastectomy rate and therefore be clinically relevant for patients. Our objective was to assess the impact of neoadjuvant chemotherapy on OS and on the rate of mastectomy in patients with non-metastatic primary operable breast carcinoma in routine practice. METHODS: The Cote d'Or district breast cancer registry was used to analyse the OS and mastectomy rate in patients with invasive primary operable unilateral breast cancer diagnosed between 1982 and 2006. We performed Cox proportional hazard ratio (HR) analyses for OS and multivariate logistic regression for the mastectomy rate for the overall population. Different matching methods based on the propensity score were used as sensitivity analyses to ensure that corrections for selection bias were adequate. RESULTS: We analysed 1578 patients, among whom 174 had received neoadjuvant chemotherapy. Median follow-up was 11.1 years. There was no difference between the two treatment groups for OS (HR=1.08 (95% confidence interval (CI): 0.77-1.51 for neoadjuvant chemotherapy)). The mastectomy rate was higher among patients treated with neoadjuvant chemotherapy (odds ratio 1.54 (95%CI: 1.03-2.31)). Sensitivity analyses confirmed these results: for OS, there was no difference between the two populations precisely matched using propensity scores (HR 1.08; 95%CI: 0.671-1.65). CONCLUSION: Despite long term follow-up, neoadjuvant chemotherapy provided no benefit for either OS or the mastectomy rate in our population.
