RESUMO

BACKGROUND: Selecting the right technique for lower limb soft tissue reconstruction is a therapeutic challenge. Despite having several reconstruction options, it's important to choose a technique that is effective and with the least possible donor site morbidity. OBJECTIVE: Demonstrate the therapeutic efficacy of the medial tab flap in soft tissue reconstruction on the leg, compared to conventional flaps. MATERIALS AND METHODS: Cohort study matched by age. 64 patients with soft tissue defects were selected and according to the intervention divided in: group 1)medial tab flap, and group 2)conventional flaps (sural, soleus, gastrocnemius) followed up to one year postoperatively. OUTCOME VARIABLES: surgical time in minutes, healing, healing time in days, complications. RESULTS: The patients who underwent surgery with medial tab flap and with conventional flaps healed completely. The healing time was 16.2±11.2 days in the tab flap and 16.1±11.2 days in conventional flaps, no statistically significant differences were found between the groups (P=.89). The surgical time for tab flaps was 225.2±117.8minutes, and 191.3±117.2minutes for the comparison flaps (P=.65), there were no statistically significant differences. There were no complications in the medial tab flaps. CONCLUSION: The findings suggest that the medial tab flap technique is as effective as the conventional flap technique, with complete flap survival and healing, and without any major complications in this studied group.

RESUMO

The BiPo-3 detector is a low radioactive detector dedicated to measuring ultra-low natural contaminations of 208Tl and 214Bi in thin materials, initially developed to measure the radiopurity of the double ß decay source foils of the SuperNEMO experiment at the µBq/kg level. The BiPo-3 technique consists in installing the foil of interest between two thin ultra-radiopure scintillators coupled to low radioactive photomultipliers. The design and performances of the detector are presented. In this paper, the final results of the 208Tl and 214Bi activity measurements of the first enriched 82Se foils are reported for the first time, showing the capability of the detector to reach sensitivities in the range of some µBq/kg.

RESUMO

We report the results of a first experimental search for lepton number violation by four units in the neutrinoless quadruple-ß decay of ^{150}Nd using a total exposure of 0.19 kg yr recorded with the NEMO-3 detector at the Modane Underground Laboratory. We find no evidence of this decay and set lower limits on the half-life in the range T_{1/2}>(1.1-3.2)×10^{21} yr at the 90% C.L., depending on the model used for the kinematic distributions of the emitted electrons.

RESUMO

WHAT IS KNOWN AND OBJECTIVE: The effect of a statin-based medical intervention on prevention of fatal and non-fatal stroke recurrence and the incidence of all-causes mortality have been explored previously in aging populations within the scope of clinical trials research. However, such evidence needs to be explored under conditions of routine clinical practice. The objective of this study was to determine whether statin therapy in patients with a first stroke episode reduces the incidence of 6-year recurrent fatal or non-fatal stroke and all-cause mortality in an aging Mediterranean population without known coronary heart disease followed in routine medical practice. METHODS: A retrospective study was carried out using records on death, hospitalizations owing to stroke and history of statin therapy included in the Badalona Serveis Assistencials (BSA) database. The cohort studied consisted of consecutive patients covered by the BSA health provider plan with a first-ever acute stroke episode during January 2003 until December 2008, for whom there was available information covering the 6-year follow-up period. Recurrence rate (RR) and incidence rate (IR) of fatal/non-fatal stroke and all-causes mortality were computed. Association with statin therapy was assessed by means of calculation of relative risk (RR) and hazard ratio (HR) using multivariate logistic regression and Cox proportional hazards models controlling for confounding covariates. RESULTS AND DISCUSSION: The cohort comprised a series of 601 consecutive patients [57% men, 75·9 (12·4) years old (88% >60 years)]. Of these, 32% received statins, which were associated with lower fatal/non-fatal recurrent stroke RR; 7% vs. 18% [adjusted RR=0·32 (CI: 0·16-0·61), P=0·001] and lower IR; 16·78 vs. 45·22 events/year-1000 subjects [adjusted HR=0·35 (0·19-0·64), P=0·001]. Similarly, observed all-causes mortality was lower in the cohort receiving statins; 11% vs. 16% [adjusted RR=0·29 (CI: 0·08-1·12), P=0·072], and also mortality rate; 26·09 vs. 36·25 deaths/year-1000 subjects [adjusted HR=0·23 (0·08-0·67), P=0·007]. WHAT IS NEW AND CONCLUSIONS: Statin therapy in patients with first-ever acute stroke lowers the risk of 6-year stroke recurrence and improves survival in an aging Mediterranean cohort. These results add additional evidence in routine clinical practice to the observed effects of statins in clinical trials.

RESUMO

We report results from the NEMO-3 experiment based on an exposure of 1275 days with 661 g of (130)Te in the form of enriched and natural tellurium foils. The ßß decay rate of (130)Te is found to be greater than zero with a significance of 7.7 standard deviations and the half-life is measured to be T(½)(2ν) = [7.0 ± 0.9(stat) ± 1.1(syst)] × 10(20) yr. This represents the most precise measurement of this half-life yet published and the first real-time observation of this decay.
