Previous studies have focused on the damaging effects of smoking and alcohol on sperm parameters;however, some of these studies have failed to find a significant correlation between these variables. Herein we have investigated the relationship of infertility with smoking and/or alcohol consumption in one hundred and thirty-six men with varicocele, admitted consecutively to the Outpatients Department of Infertility at the University of Rome La Sapienza (Italy) between 2005-2007. The sample size was small because we have selected couples with both marital infertility lasting for more than two years and the male partner with varicocele. Statistical analyses were carried out using the software of Statistical Package for the Social Sciences (SPSS). We showed a highly significant association of infertility with alcohol consumption. As the mean value was 32 years, comparing men of age less than or equal to 32 years and men of age over 32 years, this association is present only in men of age less than or equal to 32 years. A discriminant analysis with infertility as dependent variable and age, alcohol consumption and smoking habit as independent variables has shown a significant discrimination only in men of age less than or equal to 32 years. The most important contribution to this discrimination was given by alcohol followed by age while contribution from smoking was small. Our analyses suggest that alcohol consumption contributes to infertility in men of age less than or equal to 32 years whereas smoking does not.

Crop damages by wildlife is a frequent form of human-wildlife conflict. Identifying areas where the risk of crop damages is highest is pivotal to set up preventive measures and reduce conflict. Species distribution models are routinely used to predict species distribution in response of environmental changes. The aim of this paper was assessing whether species distribution models can allow to identify the areas most at risk of crop damages, helping to set up management strategies aimed at the mitigation of human-wildlife conflicts. We obtained data on wild boar Sus scrofa damages to crops in the Alta Murgia National Park, Southern Italy, and related them to landscape features, to identify areas where the risk of wild boar damages is highest. We used MaxEnt to build species distribution models. We identified the spatial scale at which landscape mostly affects the distribution damages, and optimized the regularization parameter of models, through an information-theoretic approach based on AIC. Wild boar damages quickly increased in the period 2007-2011; cereals and legtmaes were the crops more affected. Large areas of the park have a high risk of wild boar damages. The risk of damages was related to low cover of urban areas or olive grows, intermediate values of forest cover, and high values of shrubland cover within a 2-km radius. Temporally independent validation data demonstrated that models can successfully predict damages in the future. Species distribution models can accurately identify the areas most at risk of wildlife damages, as models calibrated on data collected during only a subset of years correctly predicted damages in the subsequent year [Current Zoology 60 （2）： 170-179, 2014].

Does protracted antiviral therapy impact on HCV-related liver cirrhosis progression?

AIM: To study the outcomes of patients with compensated hepatitis C virus-related cirrhosis. METHODS: Twenty-four grade A5 and 11 grade A6 of Child-Pugh classification cirrhotic patients with active virus replication, treated for a mean period of 31.3 ± 5.1 mo with moderate doses of interferon-alpha and ribavirin, were compared to a cohort of 36 patients with similar characteristics, without antiviral treatment. Salivary caffeine concentration, a liver test of microsomal function, was determined at the starting and thrice in course of therapy after a mean period of 11 ± 1.6 mo, meanwhile the resistive index of splenic artery at ultra sound Doppler, an indirect index of portal hypertension, was only measured at the beginning and the end of study. RESULTS: Eight out of the 24 A5- (33.3%) and 5 out of the 11 A6- (45.45%) treated-cirrhotic patients showed a significant improvement in the total overnight salivary caffeine assessment. A reduction up to 20% of the resistive index of splenic artery was obtained in 3 out of the 8 A5- (37.5%) and in 2 out of the 5 A6- (40%) cirrhotic patients with an improved liver function, which showed a clear tendency to decrease at the end of therapy. The hepatitis C virus clearance was achieved in 3 out of the 24 (12.5%) A5- and 1 out of the 11 (0.091%) A6-patients after a median period of 8.5 mo combined therapy. In the cohort of non-treated cirrhotic patients, not only the considered parameters remained unchanged, but 3 patients (8.3%) had a worsening ofthe Child-Pugh score (P = 0.001).CONCLUSION: A prolonged antiviral therapy with moderate dosages of interferon-alpha and ribavirin shows a trend to stable liver function or to ameliorate the residual liver function, the entity of portal hypertension and the compensation status at acceptable costs.

AIM: To evaluate neutrophil gelatinase associated lipocalin(NGAL) in patients infected by hepatitis C virus(HCV) before and during treatment with directly acting antivirals(DAAs).METHODS: NGAL was measured in a group of patients with chronic HCV infection ranked, at baseline, by age, gender, anti-hypertensive therapy, HCV viral load, liver fibrosis stage and, either at baseline or after 1 year, estimated glomerular filtration rate(e GFR). Then, NGAL and e GFR evolutions were monitored in a subgroup of patients who started antiviral therapy with DAAs. Differences of median NGAL levels were evaluated through Wilcoxon-Mann-Whitney test for nonparametric data. Differences in dichotomous variables were evaluated through χ~2 test. At baseline, a univariate regression analysis was conducted to verify if NGAL values correlated with other quantitative variables [age, fibrosis four(FIB-4), AST to platelet ratio index(APRI), and e GFR]. RESULTS: Overall, 48 patients were enrolled, 8 of them starting HCV treatment. At baseline, statistically significant differences were found in median NGAL values only between patients with e GFR 118.11 ng/d L were compared with those of NGAL ≤ 118.11 ng/d L, not statistically significant differences were present for age, gender, chronic kidney disease classification and liver fibrosis(P > 0.05). Linear correlation was found between NGAL and both age(P = 0.0475) and e GFR(P = 0.0282) values. Not statistically significant predictions of NGAL at baseline were demonstrated for e GFR evolution 1 year later. Interestingly, in the 8 patients treated with DAAs, median NGAL significantly increased at week 12 compared to baseline(P = 0.0239).CONCLUSION: Our results suggest that NGAL should be further evaluated as an adjunct marker of kidney function in these patients.

Cholangiocarcinoma(CCA) is a malignant tumour that arises from biliary epithelium at any portion of the biliary *** is currently classified as intra-hepatic or extra-hepatic CCA(EH-CCA).Recent evidences suggest that intra-hepatic CCA(IH-CCA) and EH-CCA are biologically different cancers,giving further support to a number of recent epidemiological studies showing large differences in terms of incidence,mortality and risk *** purpose of this manuscript is to review recent literature dealing with the descriptive epidemiology and risk factors of CCA with a special effort to compare IH-with EH-CCA.
