Extranodal extension of nodal metastasis is the main prognostic moderator in squamous cell carcinoma of the esophagus after neoadjuvant chemoradiothe…
2017
Several studies, including comprehensive systematic reviews with meta-analyses of our group of research, have demonstrated the negative prognostic impact of the extranodal extension of nodal metastasis (ENE) in different cancer types, including squamous cell carcinoma (SCC) of the vulva, of the penis and of head and neck, as well as in tumors of the digestive and genitourinary systems, in thyroid cancer and others (1-17).
Josamycin Concentration in Human Ejaculate and its Influence on Sperm Motility/Josamycinkonzentrationsbestimmung in menschlichem Ejakulat und deren E…
2009
The concentration of josamycin was determined in the split ejaculate of 5 volunteers after oral administration for several days. One aim of this investigation was to examine the penetration of the macrolide antibiotic into the prostate and the seminal vesicles. 2.23 +/- 1.8 micrograms/ml josamycin was found in fraction I of the ejaculate, consisting mostly of prostatic secretion, and 1.56 +/- 1.37 micrograms/ml josamycin in fraction II comprising mainly secretions from the seminal vesicles. The concentrations of josamycin found in both fractions of the ejaculate are clearly comparable with serum levels of the antibiotic. Josamycin thus attains concentrations in the prostate and seminal vesi…
Genome-Wide Linkage Scan in a Moroccan Family With Autosomal-Recessive Exstrophy of the Bladder Identifies a Novel Susceptibility Locus on Chromosome…
2009
Purpose Exstrophy of the bladder (EB) is part of the bladder exstrophy-epispadias complex (BEEC) representing a spectrum of urogenital anomalies in which part or all of the distal urinary tract fail to close and are exposed on the outer abdominal wall. Familial occurrence is rare and previous studies are suggestive of an underlying multifactorial mode of inheritance. However, no causally related genetic or non-genetic factor has been identified so far. In this study, we aim to identify potential risk/modifying loci that might contribute to EB. Material and Methods A genome-wide linkage scan was performed in a consanguineous kindred of Moroccan origin where three affected males showed the sa…
Executive summary of the 2018 KDIGO Hepatitis C in CKD Guideline: welcoming advances in evaluation and management
2018
Infection with the hepatitis C virus (HCV) has adverse liver, kidney, and cardiovascular consequences in patients with chronic kidney disease (CKD), including those on dialysis therapy and in those with a kidney transplant. Since the publication of the original Kidney Disease: Improving Global Outcomes (KDIGO) HCV Guideline in 2008, major advances in HCV management, particularly with the advent of direct-acting antiviral therapies, have now made the cure of HCV possible in CKD patients. In addition, diagnostic techniques have evolved to enable the noninvasive diagnosis of liver fibrosis. Therefore, the Work Group undertook a comprehensive review and update of the KDIGO HCV in CKD Guideline.…
Spermiogram and sperm head morphometry assessed by multivariate cluster analysis results during adolescence (12-18 years) and the effect of varicocele
2016
Artículo científico This work evaluates sperm head morphometric characteristics in adolescents from 12 to 18 years of age, and the effect of varicocele. Volunteers between 150 and 224 months of age (mean 191, n = 87), who had reached oigarche by 12 years old, were recruited in the area of Barranquilla, Colombia. Morphometric analysis of sperm heads was performed with principal component (PC) and discriminant analysis. Combining seminal fluid and sperm parameters provided five PCs: two related to sperm morphometry, one to sperm motility, and two to seminal fluid components. Discriminant analysis on the morphometric results of varicocele and nonvaricocele groups did not provide a useful class…
Growth patterns and associated risk factors of congenital malformations in twins.
2020
AbstractBackgroundThe rate of twinning continues to increase due to the combined effect of a rise in parental age and increased use of assisted reproductive technology. The risk of congenital anomalies in twins is higher than in singletons, but it is less well reported in relation to growth patterns. We focused to the auxological outcome of twin pregnancies when one or both of twins are affected by one or more malformations.MethodsWe conducted a retrospective observational study reviewing the clinical charts of twins admitted in the period between January 2003 and December 2018 at the University Hospital of Palermo. The associations between malformations and anthropometric variables at birt…
Comparison of different statistical approaches to evaluate morphometric sperm subpopulations in men.
2016
This study was designed to characterize morphometric sperm subpopulations in normozoospermic men by using different statistical methods and examining their suitability to classify correctly different sperm nuclear morphologies present in human ejaculates. Ejaculates from 21 normozoospermic men were collected for the study. After semen collection and analysis, samples were prepared for morphometric determination. At least 200 spermatozoa per sample were assessed for sperm morphometry by computer-assisted sperm morphometry analysis (CASA-Morph) using fluorescence. Clustering and discriminant procedures were performed to identify sperm subpopulations from the morphometric data obtained. Cluste…
Cardiovascular risk factors and the impact on prognosis in patients with chronic kidney disease secondary to autosomal dominant polycystic kidney dis…
2021
Background: Autosomal dominant polycystic kidney disease (ADPKD) is the most frequent hereditary renal disease. There is an increased rate of cardiovascular disease (CVD) in ADPKD. In this study, we evaluate the prevalence of cardiovascular risk factors, the achievement rates for treatment goals and cardiovascular events (CVE) in ADPKD and their relations with asymptomatic CVD in CKD from other etiologies (CKDoe) and controls. Methods: We evaluated 2445 CKD patients (2010–2012). The information collected was: clinical, anthropometric and analytical parameters, treatments and CVD evaluation (intima-media thickness (IMT), atheromatous plaque presence and ankle-brachial index (ABI)). Laborator…
Kinetics of serum total and free prostate-specific antigen (PSA) after extended multisite prostate biopsy: Comparison among biopsy, transurethral res…
2008
Abstract Background The kinetics and reproducibility of serum prostate-specific antigen (PSA) following extended multisite biopsies are unknown. The aim of this study was to examine the kinetics of hematogenous leakage of PSA molecules by comparing the postintervention PSA manner among extended biopsies, transurethral resection of the prostate (TURP) and biopsy plus TURP. Methods Total and free PSA values were examined before and sequentially after intervention (at 1 hour, 24 hours, 2 days, 14 days, and 28 days), in patients who underwent 14-core prostate biopsy (Biopsy, n = 53), TURP (TURP, n = 21), or prostate biopsy plus TURP (Biopsy+TURP, n = 18). Results Ten patients in the Biopsy grou…
Characterization of human infiltrating and circulating gamma-delta T cells in prostate cancer
2019
Purpose The aim of our study was to prospectively evaluate the distribution of gamma-delta (γδ)1 and γδ2 T cells and their phenotypes in peripheral blood and prostate samples of patients diagnosed with or without prostate cancer (PCa) at prostate biopsy. Materials and methods A consecutive series of 43 outpatients underwent trans-rectal echo-guided prostate biopsy for suspected PCa. Flow cytometry analysis was used to identify and characterize the γδ T cells populations in peripheral blood and tissue samples. Patients were stratified according to the presence or not of PCa, and its International Society of Urological Pathology (ISUP) grade (1 vs. ≥2). Results The distribution of γδ T cells …
