Muscle fiber-type distribution predicts weight gain and unfavorable left ventricular geometry: a 19 year follow-up study
2006
Abstract Background Skeletal muscle consists of type-I (slow-twitch) and type-II (fast-twitch) fibers, with proportions highly variable between individuals and mostly determined by genetic factors. Cross-sectional studies have associated low percentage of type-I fibers (type-I%) with many cardiovascular risk factors. Methods We investigated whether baseline type-I% predicts left ventricular (LV) structure and function at 19-year follow-up, and if so, which are the strongest mediating factors. At baseline in 1984 muscle fiber-type distribution (by actomyosin ATPase staining) was studied in 63 healthy men (aged 32–58 years). The follow-up in 2003 included echocardiography, measurement of obes…
Comprehensive laparoscopic approach to pediatric varicocele based on preoperative color Doppler ultrasound assessment
2008
Abstract: Background This study aimed to assess whether laparoscopic treatment for any kind of varicocele is possible after preoperative identification of refluxing veins by color Doppler ultrasound (CDUS). Methods At the authors'' institution, 98 patients with a median age of 11.3 years (range, 7.1-16 years) were evaluated for a left varicocele. Preoperatively, all the patients underwent ultrasound scan assessment of testicular volume and CDUS to rule out reflux into the internal spermatic vein (ISV), deferential vein, or cremasteric vein. In all the patients, laparoscopic division of the spermatic artery and veins was performed as close as possible to the internal inguinal ring. The other…
Prognostic value of dipyridamole stress cardiovascular magnetic resonance imaging in patients with known or suspected coronary artery disease.
2007
ObjectivesWe evaluated the prognostic value of dipyridamole stress cardiovascular magnetic resonance imaging (CMR) in patients with chest pain and known or suspected coronary artery disease.BackgroundStress perfusion CMR has been incorporated in daily practice. Data on its prognostic value are preliminary.MethodsDipyridamole stress CMR was performed in 420 patients with chest pain and known or suspected coronary artery disease. The extent (number of segments according to the 17-segment model) of abnormal wall motion at rest (AWM-rest), abnormal wall motion with dipyridamole (AWM-D), perfusion deficit (at stress first-pass perfusion imaging), and delayed enhancement (at late enhancement imag…
Significance of the effective remnant liver volume in major hepatectomies
2005
The aim of this study is to identify the minimum safe amount of effective remnant liver volume (ERLV) in patients undergoing a major hepatectomy. Thirty-eight consecutive major hepatectomies (resection of ≥3 Couinaud segments) performed between July 1999 and March 2004 in which a frozen section liver biopsy was obtained were included. No patient had chronic viral hepatitis, cirrhosis, or cholestasis. The total liver volume (TLV) was calculated using the Vauthey formula, and the postsurgical liver volume (PSLV) was derived by subtracting the estimated volume of liver resected from the TLV. The PSLV minus the percentage of macrovesicular steatosis as nonfunctional liver was defined as the ef…
Detecting spatio-temporal mortality clusters of European countries by sex and age.
2018
[EN] Background: Mortality decreased in European Union (EU) countries during the last century. Despite these similar trends, there are still considerable differences in the levels of mortality between Eastern and Western European countries. Sub-group analysis of mortality in Europe for different age and sex groups is common, however to our knowledge a spatio-temporal methodology as in this study has not been applied to detect significant spatial dependence and interaction with time. Thus, the objective of this paper is to quantify the dynamics of mortality in Europe and detect significant clusters of mortality between European countries, applying spatio-temporal methodology. In addition, th…
Influence of Concurrent Obesity and Low Birth Weight on Blood Pressure Phenotype in Youth
2009
The aim of this study was to assess the impact of obesity and low birth weight on both office and ambulatory blood pressure (BP) values, as well as on aortic-derived parameters in youths. A total of 422 white youths, from 10 to 18 years of age, were included. Subjects were divided into 4 groups according to the presence (234; 55%) or the absence (188; 45%) of obesity and according to low (114; 27%) or normal (308; 73%, birth weight. Spacelabs 90207 was used to measure ambulatory BP during a 24-hour period. SphygmoCor radial/aortic transform software was used to estimate aortic pressure waveform. Office, 24-hour, daytime, and nighttime systolic BP values were significantly higher in those s…
Chronic constipation and food intolerance: A model of proctitis causing constipation
2005
OBJECTIVE: Chronic constipation in children can be linked to cow''s milk intolerance (CMI) but the existence of a food intolerance-dependent proctitis is still debated. The aim of this study was to evaluate the histologic data in patients with food intolerance-related constipation. MATERIAL AND METHODS: Fifty-two consecutive patients (22 M, median age 4 years) with chronic constipation unresponsive to common treatment were enrolled. All patients were put on a cow''s milk-free diet for 4 weeks and those uncured on this diet underwent a subsequent 4-week period of oligoantigenic diet. In the patients cured on elimination diet, a subsequent double-blind food challenge was performed to confirm …
Cumulative incidence of achilles tendon rupture and tendinopathy in male former elite athletes
2005
To study the cumulative incidence of Achilles tendon rupture and tendinopathy among former top-level athletes.Historical cohort study.Finland.Male former elite athlete cohort members (n = 785; median age, 69 years when responding to the questionnaire; range, 54-97) and their matched controls (n = 416; median age, 68 years; range, 56-94).Questionnaire-reported Achilles tendinopathy and tendon rupture diagnosed by physicians before the age of 45 years and within the subjects' lifetimes.Cumulative incidence of Achilles tendinopathy before the age of 45 was high for middle and long-distance runners (adjusted odds ratio, 31.2 compared with controls; P0.001), and cumulative incidence of Achilles …
Inadequate oral anticoagulation with warfarin in women with cerebrovascular event and history of atrial fibrillation: the FibStroke study
2021
Abstract Background Women with atrial fibrillation (AF) may be treated less actively with oral anticoagulation (OAC) than men. Patients and methods We assessed sex differences in the implementation of stroke risk stratification with CHADS2 and CHA2DS2-VASc scores and reasons not to use OAC in 1747 AF patients suffering their first cerebrovascular event after the AF diagnosis. Results Women were older and had more often a high stroke risk (CHADS2/CHA2DS2-VASc ≥2) than men (p < .001). On admission, 46.4% of women and 48.2% of men were on OAC with no sex difference (p = .437). However, of patients without OAC, 74.4% of women and 49.5% of men should have been on OAC based on CHADS2/CHA2DS2-VASc…
Microstructure of rat behavioral response to anxiety in hole-board
2010
Aim of present research was to assess, by means of descriptive and multivariate approaches, in Wistar rats tested in hole-board apparatus, whether a microstructure of hole exploratory behavior may be identified in the behavioral response to anxiety. Two groups of 15 subjects were tested: one received 1 ml of saline IP and one was IP injected with diazepam at 0.5 mg/kg dissolved in 1 ml of saline. Following saline, six not yet reported hole-exploratory components were identified: active-dip, static-dip, rapid-dip, circular-sniff, point-sniff and central-sniff. Diazepam provoked significant changes of their per cent distribution. Results of multivariate analyses revealed a complex microstruct…
