Assessment of volume preservation performed before or after partial nephrectomy accurately predicts postoperative renal function: Results from a prospective multicenter study

Purpose

Partial nephrectomy (PN) is standard for small renal masses, improving renal function by preserving renal parenchyma compared with radical nephrectomy. Recent work demonstrated that postoperative surgeon assessment of volume preservation (SAVP) and 3D imaging measurements agree and correlate with postoperative function. We hypothesize preoperative assessment of volume preservation (PAVP) with PN based on preoperative imaging will reliably indicate postoperative renal function.

Westernization of the Filipino population resident in Rome: obesity, diabetes and hypertension

BACKGROUND: Aims of the present study were to examine the anthropometrical and metabolic characteristics of the Filipino population migrant to the Southern European city of Rome, Italy. METHODS: A cross-sectional study was carried out in the city of Rome. Three hundred thirty-five Filipinos (95 M/240 F, mean age: 44.0+/-9.8 years, mean residence in Italy: 12.9+/-6.3 years) were studied. Data were collected by standardized questionnaires; anthropometrical parameters, arterial pressure, and fasting capillary blood glucose (FCG) were measured. RESULTS: Abdominal obesity was found in 52.5%, and BMI >or= 25 kg/m(2) in 44.5% of subjects. History of type 2 diabetes mellitus (T2DM) and hypertension were reported by 6.0 and 9.0% of subjects, respectively. Impaired fasting glucose was found in 13.1%, and FCG >or= 110 mg/dl in 18.5% of subjects. Altered systolic and/or diastolic blood pressure was found in 34.3% of subjects. About three-fourths of subjects were unaware of being diabetic and/or hypertensive. Years of Italy residence showed a direct significant correlation with the degree of changes in alimentary behaviours (rho=0.18, p=0.001), and with weight gain (rho=0.27, p<0.001). Multivariate analysis showed only age and waist circumference to be associated with both diabetes and hypertension. CONCLUSIONS: In the present study, the first to examine the metabolic disorders in a migrant Filipino population resident in Rome, a high prevalence of obesity, diabetes, and hypertension was found. The alarming results emerging from this study should be seriously considered by public health practitioners and decision makers, and made known to the Filipinos resident in Europe.     

Antiendomysial and antihuman recombinant tissue transglutaminase antibodies in the diagnosis of coeliac disease: a biopsy-proven European multicentre study

OBJECTIVE: To investigate the value of serum antitissue transglutaminase IgA antibodies (IgA-TTG) and IgA antiendomysial antibodies (IgA-EMA) in the diagnosis of coeliac disease in cohorts from different geographical areas in Europe. The setting allowed a further comparison between the antibody results and the conventional small-intestinal histology. METHODS: A total of 144 cases with coeliac disease [median age 19.5 years (range 0.9-81.4)], and 127 disease controls [median age 29.2 years (range 0.5-79.0)], were recruited, on the basis of biopsy, from 13 centres in nine countries. All biopsy specimens were re-evaluated and classified blindly a second time by two investigators. IgA-TTG were determined by ELISA with human recombinant antigen and IgA-EMA by an immunofluorescence test with human umbilical cord as antigen. RESULTS: The quality of the biopsy specimens was not acceptable in 29 (10.7%) of 271 cases and a reliable judgement could not be made, mainly due to poor orientation of the samples. The primary clinical diagnosis and the second classification of the biopsy specimens were divergent in nine cases, and one patient was initially enrolled in the wrong group. Thus, 126 coeliac patients and 106 controls, verified by biopsy, remained for final analysis. The sensitivity of IgA-TTG was 94% and IgA-EMA 89%, the specificity was 99% and 98%, respectively. CONCLUSIONS: Serum IgA-TTG measurement is effective and at least as good as IgA-EMA in the identification of coeliac disease. Due to a high percentage of poor histological specimens, the diagnosis of coeliac disease should not depend only on biopsy, but in addition the clinical picture and serology should be considered.

Plasma levels of cell adhesion molecules during hyperinsulinemia and modulation of vasoactive mediators

Endothelial expression of cell adhesion molecules (CAMs) plays an important role in atherosclerosis. Atherosclerosis is increased in hyperinsulinemic states, but whether insulin per se is proatherogenic remains unclear. To investigate the effects of hyperinsulinemia on CAM expression, plasma levels of ICAM-1, VCAM-1 and E-selectin were measured before and after forearm infusion of insulin in healthy subjects. Insulin administration for 2h resulted in significant hyperinsulinemia, whereas no significant change was observed in soluble CAMs (all p > 0.05). Because insulin stimulates endothelial release of both endothelin-1 (ET-1) and nitric oxide (NO), which may modulate the expression of CAMs, we also investigated the response of CAMs to ET-1 receptor blockade, alone and in combination with NO synthesis inhibition. ET-1 receptor blockade during hyperinsulinemia resulted in a vasodilator response, but did not affect soluble CAMs (all p > 0.05). Superimposition of NO inhibition by L-NMMA reversed the vasodilator effect of ET-1 blockade, without affecting soluble CAMs (all p > 0.05). In conclusion, acute hyperinsulinemia, alone or during ET-1 and NO pathway blockade, does not affect soluble CAMs. These results do not support a direct effect of insulin on endothelial cells to affect leukocyte adhesiveness to the vascular wall.
