Effect of fatigue strength exercise on anterior thigh skin temperature rewarming after cold stress test.
2021
Although dynamic thermography skin temperature assessment has been used in medical field, scientific evidence in sports is scarce. The aim of the study was to assess changes in anterior thigh skin temperature in response to a cold stress test after a strength exercise fatiguing protocol. Ten physically active adults performed a familiarization session and two strength exercise sessions, one with dominant and the other with non-dominant lower limb. Participants performed bouts of 10 concentric and eccentric contractions of leg extensions in an isokinetic device until reaching around 30% of force loss. Infrared thermographic images were taken at baseline conditions and after the fatigue level…
Differential regulation of Fas-mediated apoptosis in both thyrocyte and lymphocyte cellular compartments correlates with opposite phenotypic manifest…
2001
Several mechanisms are probably involved in determining the evolution of autoimmune thyroid disease (AITD) towards either hypothyroidism and the clinical syndrome known as Hashimoto's thyroiditis (HT) or toward hyperthyroidism and the symptoms of Graves' disease (GD). To gain further insight into such mechanisms we performed an exhaustive comparative analysis of the expression of key molecules regulating cell death (Fas, Fas ligand [FasL], Bcl-2) and apoptosis in both thyrocytes and thyroid infiltrating lymphocytes (TILs) from patients with either GD or HT. GD thyrocytes expressed less Fas/FasL than HT thyrocytes, whereas GD TILs had higher levels of Fas/FasL than HT TILs. GD thyrocytes exp…
Bilateral ureteral obstruction and renal failure caused by massive retroperitoneal hematoma: is there a pelvic compartment syndrome analogous to abdo…
1998
Objectives: To describe an intrapelvic compartment syndrome analogous to abdominal compartment syndrome and to characterize its diagnosis and treatment. Design: Retrospective analysis. Setting: Level I trauma center. Patients: Three patients with pelvic ring or acetabular fractures presented with bilateral ureteral obstruction, renal organ failure. and anuria due to direct compression of both ureters in the true pelvis by a massive retroperitoneal hematoma, Intervention: Surgical therapy consisted of fracture stabilization, decompression of the retroperitoneal space, and evacuation of the hematoma. Persistent isolated bleeding points were either embolized preoperatively or ligated. Results:…
Reproducibility of Regional DEXA Examinations of Abdominal Fat and Lean Tissue
2013
<b><i>Objective: </i></b>The aim of this study was to develop and test the validity of a new repeatable method to delimit abdominal areas for follow-up of fat mass (FM) and lean tissue mass (LM) in DEXA examinations<i>. </i><b><i>Methods: </i></b>37 male volunteers underwent two DEXA examinations. Total body FM and LM measurements and corresponding abdominal measurements in a carefully defined region were calculated from the first scan. After repositioning of the subjects and a second scan, the delimited region was copied and the abdominal tissues re-calculated. <b><i>Results: </i></b>The mean LM of the abdo…
PTFE mesh in renal allograft compartment syndrome.
2006
We report a case of anuria in a 42-year-old female kidney transplant patient that occurred secondary to extrinsic compression from a large kidney being placed extraperitoneally in a small iliac fossa. Prompt reexploration in the immediate postoperative period resulted in salvage of the graft with restoration of kidney function. The abdominal wall was reconstructed using prosthetic mesh, which decreased the compartment pressure within the iliac fossa sufficiently to allow the renal vein patency and the kidney perfusion. We think that this tension-free surgical technique should be applied in those cases in which the retroperitoneal space is less than the size of the kidney to avoid renal allo…
Mesh or no mesh: a hamletic dilemma to prevent Renal Allograft Compartment Syndrome (RACS)
2014
Tension-free muscle closure is essential in kidney transplantation, both in adult and pediatric patients. Tight muscle closure may lead to renal allograft compartment syndrome either due to compression of the renal parenchyma or due to kinking of the renal vessels. It may also cause kinking of the transplant kidney ureter, wound dehiscence and incisional hernia. Many techniques have been proposed in an attempt to achieve tension-free closure. There is a wrong belief among surgeons that using prosthetic mesh may increase the incidence of infective complications in these immunosuppressed patients. Also, there is fear that one is not able to monitor the renal graft by ultrasound and perform bi…
B Cells Compartment in Centenarian Offspring and Old People
2010
Immunosenescence is considered a major contributory factor to the increased frequency of morbidity and mortality among elderly. On the other hand centenarians are considered the best example of successful ageing. To gain insight into mechanisms of immunosenescence and its clinical relevance, a possible model is represented by centenarians and/or their offspring. Nowadays centenarians are not more a curiosity, but in Europe are 1/8000 inhabitants and it has been demonstrated that the centenarian offspring, who are typically in their 70s and 80s, have a survival advantage when compared with age-matched controls whose parents died at an average life expectancy. Then again, studies on immunosen…
A popliteal artery aneurysm presenting with ab extrinseco popliteal vein occlusion and compartment syndrome
2012
INTRODUCTION: Aneurysms of popliteal artery are the most frequently reported aneurysm after abdominal aorta. An unusual presentation is compression to adjacent structure. CASE PRESENTATION: A 67 years old caucasian man presenting deep vein thrombosis signs to the right leg including functional impotence was admitted in emergency setting to Vascular Surgery Unit. A pulsing mass was present in the popliteal cave at inspection. The computed tomography angiography demonstrated a 53.2 mm popliteal artery aneurysm causing an ab extrinseco compression of the popliteal vein and a dislocation of popliteal nerve. A surgical open reconstruction with a reinforced Dacron graft was performed via a poster…
El análisis cuantitativo de trayectorias laborales. Un estado del arte
2022
La metodología cuantitativa aplicada al estudio de las trayectorias laborales ha experimentado un rápido auge que se ha extendido más allá del tradicional análisis de secuencias. El presente artículo es un estado del arte del desarrollo de nuevas técnicas estadísticas que pueden aplicarse o ya se aplican al estudio de trayectorias laborales. Además, incluimos sugerencias de software estadístico para la aplicación de cada una de las técnicas descritas. A lo largo de todo el texto, podrá observarse que la descripción de cada técnica se ha realizado desde un punto de vista conceptual, con el objetivo de llegar a un público amplio, que no necesite poseer una fuerte formación estadística. Es med…
Acute hazard of biocides for the aquatic environmental compartment from a life-cycle perspective
2019
One of the aims of the European project LIFE-COMBASE is to build a computational tool to predict the acute toxicity for aquatic organisms of biocidal active substances and its environmental degradation products. A database was implemented compiling toxicity data for these substances in organisms of the freshwater/marine and sewage treatment plant compartments. The goal of this study is to analyze the compiled data to identify the possible hazard of these compounds for the aquatic compartments. Several official and scientific databases were consulted. Data from 196 biocidal substances and 206 environmental metabolites were collected for the taxonomic groups, including fish, invertebrates, al…
