Aortomesenteric fat thickness with ultrasound predicts metabolic diseases in obese patients
BACKGROUND:: The relation between visceral fat accumulation and development of cardiovascular and metabolic disorders has been demonstrated. The aim of this study was to determine the relationship between a new ultrasound visceral fat thickness (VFT) measurement and clinical and anthropometric data in a consecutive series of obese patients. METHODS:: Fifty-five consecutive male obese patients underwent ultrasound evaluation and metabolic and anthropometric parameters determination at baseline and after 3 weeks of a very low-calorie diet (VLCD) therapy. The new ultrasound measurement, the thickness of the fat between the aorta and the superior mesenteric artery (AMFT), was determined along with the maximum thickness of preperitoneal fat and the global VFT. RESULTS:: AMFT showed a better correlation than VFT and preperitoneal fat with all anthropometric and metabolic parameters, both at baseline and after VLCD regimen. At baseline, patients in the middle and high AMFT and VFT tertiles had a significantly higher prevalence of metabolic diseases with respect to AMFT and VFT low tertile patients, whereas after VLCD period, AMFT only showed significant difference within tertiles. The odds ratios for the various metabolic diseases were higher in the middle and high AMFT tertiles than those in the middle and high VFT tertiles, remaining significant after adjustment for age, body mass index and VLCD regimen only in the middle and high AMFT tertiles. CONCLUSIONS:: The ultrasonographic AMFT evaluation is strongly correlated to the presence of metabolic syndrome and could be a valuable tool to predict metabolic diseases and associated cardiovascular risks in men. © 2013 Lippincott Williams and Wilkins

Men buying sex. Differences between urban and rural areas in UK
We build on both our theoretical and empirical work on modelling the demand for paid sex (Della Giusta et al., 2009a, 2009b) and examine the demand for paid sex, considering the effects of risky behaviours and attitudes to relationships and to women on demand. We find that those who declare to have purchased sex have both different socio-demographics (older, with fewer children, more educated but with lower professional status), and different sexual and risky behaviours as well as attitudes to relationships. As expected in the light of findings in the literature (well summarised in a 2004 Urban Studies special issue and in more recent literature) a clear city effect in the sample, mostly driven by London, which goes beyond the attitudes captured in the survey and thus combines a mixture of factors related to the supply of paid sex and unobserved characteristics of city-dwelling respondents
Endovascular Stent Grafts as a Safe Secondary Option for Paraanastomotic Abdominal Aortic Aneurysm
ObjectiveTo describe our experience of endovascular repair of paraanastomotic aortic aneurysm.Methods and resultsFrom March 2001 to December 2004 we identified 6 patients with a paraanastomotic aortic aneurysms following previous open repair of abdominal aortic aneurysm. All patients were treated with endovascular surgery under epidural anaesthesia. There were no major complications, surgical conversions or deaths. Four patients received a bifurcated aortic stent-graft, and two an aorto-uniliac stent-graft followed by a femoro-femoral bypass. At follow-up (mean 26.1±10.2 months) there were no deaths, endoleaks or graft migrations observed.ConclusionEndovascular surgery, avoiding general anesthesia and re-laparotomy, is the ideal technique for treatment of this complication resulting from failed primary conventional AAA repair
