Child rearing or childbearing? Risk of cardiovascular diseases associated to parity and number of children.

BACKGROUND: An increased risk of cardiovascular diseases (CVD) has been associated with women's parity, but whether or not this association reflects a direct pregnancy effect, or exposure to factors related to childrearing, still appears unclear. We assessed the CVD risk associated with number of children separately by gender and tested effect modification by socioeconomic position (SEP) and employment status, in order to elucidate the possible mechanisms underlying this association. METHODS: The study population was composed of 20,904 men and 25,246 women who were interviewed in one of two National Health Surveys conducted in 2000 and 2005 in Italy. These subjects were followed for CVD incidence up to 2014 through record-linkage with national archives of mortality and hospitalisations. CVD risk was estimated by Cox regression models that were adjusted for socio-demographics, perceived health, lifestyles, biological CVD risk factors and for other potential confounders. RESULTS: CVD incidence was significantly increased among men with 3 or more children (HR = 1.26, 95% CI: 1.02-1.56) and among women with 2 and with 3 or more children (HR = 1.42, 95% CI: 1.10-1.83; and HR = 1.39, 95% CI: 1.03-1.87, respectively) compared to subjects without children and no significant gender differences were observed. Subjects with lower SEP displayed stronger associations with parity and a higher number of children for both genders; by contrast, no modifying effect of employment status was observed. CONCLUSIONS: Taken together, the significant association between higher parity and CVD risk in both genders, and the higher risk of CVD associated with higher parity among lower SEP parents, suggests that childrearing has a potential effect on the development of CVD that is more pronounced among disadvantaged families, although a concurrent effect of childbearing cannot be completely excluded.

Occupational physical activity, all-cause mortality and incidence of cardiovascular diseases: results from three Italian cohorts.

PURPOSE: To examine the association of exposure to Occupational Physical Activity (OPA) with all-cause mortality and incidence of cardiovascular diseases (CVD). METHODS: The study population was composed of three Italian cohorts: a national cohort of employees participating in the National Health Survey 2005, followed-up until 2014 (ILS 2005), and two urban cohorts of employees resident in Turin at 2001 and 2011 censuses (TLS 2001 and TLS 2011, respectively), both followed-up until 2018. Follow-up was conducted through individual record-linkage with death registries and hospital admissions archives. Exposure to OPA was assigned through an Italian job-exposure matrix (JEM). Relative Risks of both CVD incidence and overall mortality associated with OPA quartiles (IRR) were estimated using Poisson regression models adjusted for socio-demographics and health, and in the national cohort, also for leisure time physical activity, BMI, smoking, diabetes, and hypertension. RESULTS: Compared to the lowest quartile, the highest OPA quartile was associated in both genders with significantly increased mortality in TLS 2001 (IRR = 1.11 among men, IRR = 1.20 among women) and in TLS 2011 (IRR = 1.27 among men and IRR = 1.73 among women), whereas in the ILS 2005 cohort no association was found. Among women, high OPA was also associated with CVD risk in TLS 2001 and 2011 (IRR = 1.39 and IRR = 1.16 for the highest quartile, respectively), while in the ILS cohort in both genders only the third quartile showed a significantly higher risk. CONCLUSION: Our results indicate that OPA does not have a beneficial effect on CVD and mortality, but rather suggest that it may produce deleterious health effects.

Incidence of knee and hip joint replacement associated with cumulative exposure to physical factors at work.

BACKGROUND: Knee osteoarthritis (OA) has been quite consistently associated with high physical workload and specific physical factors at work, while for hip OA, fewer studies are available, which still indicate possible associations with heavy lifting and physical workload. The objective of the study was to assess the association between exposure to workplace physical factors and incidence of knee and hip arthroplasty, as markers of severe OA in these joints. METHODS: The study population was composed of employees 25-60 years who participated in the Turin 2011 census. For each job held since 1995, exposure to physical factors was assigned to individuals in the cohort through a Job-Exposure Matrix constructed from the Italian O*NET database. Using Poisson regression models, the incidence of knee and hip arthroplasty for OA, identified through hospitalizations from 2012 to 2018, was examined in relation to cumulative exposure to 7 different physical hazards and a composite indicator of physical workload constructed from 17 physical factors (Ergo-Index). RESULTS: The risk of knee OA was significantly increased in the highest cumulative exposure quartile of physical workload (incidence rate ratio = 1.98, 95% confidence interval: 1.24-3.16) and of all single hazards examined, compared to the lowest quartile, with significant trends in risk with increasing exposure. In contrast, no association was found with hip OA, whose relative risks were close to or below one in all higher-exposure quartiles of physical workload and of each single hazard. CONCLUSIONS: Our results indicate that exposure to physical hazards at work increases the likelihood of developing knee OA, but not hip OA.

Risk of symptomatic osteoarthritis associated with exposure to ergonomic factors at work in a nationwide Italian survey.

OBJECTIVE: The risk of developing osteoarthritis (OA) has been reported to increase with exposure to various ergonomic factors at work, although this finding is still debated in the literature. Aim of this study was to assess the association between prevalence of symptomatic OA and exposure to workplace ergonomic factors assigned through a job-exposures matrix (JEM). METHODS: The study population was composed of 24,604 persons of 40-69 years who participated in the National Health Survey 2013 and were employed at that occasion. Exposure to ergonomic factors was assigned to the study population through a JEM constructed from the Italian O*NET database, consisting of 17 physical factors, which were summed and averaged by job title (796 jobs) to obtain a combined exposure index. The outcome was self-reported OA characterized by moderate or severe limitations in daily activities. The relationship between OA prevalence and the combined exposure index in quartiles was examined using robust Poisson regression models adjusted for socio-demographics and potential confounders. RESULTS: In the analysis adjusted for age and gender, the risk of OA was increased by approximately 20-30% in the second and third quartiles, and by 80% in the highest exposure quartile, compared to the least exposed, with a risk attenuation by approximately 15-20% controlling for other significant covariates. CONCLUSION: Our results support a causal role of exposure to physical factors at work in the development of OA. As OA is associated with a great burden of disability, any effort should be made to reduce workers' exposure to ergonomic factors.

Agreement between observed and interview-based exposure to ergonomics factors for the upper extremities in employees of a package sorting plant.

Aim of the study was to estimate agreement between observational and interview-based exposure to ergonomic factors at work. Thirty-two male workers employed in a logistics hub were interviewed through the OCRA check-list on exposure to ergonomic factors in one of six work tasks. Observations of workers in each work task, based on the same OCRA check-list, were used to assess exposure in that task. Agreement between observed and interview-based scores of the check-list OCRA index, as well as of frequency and posture, was estimated both at individual and task group level through the Intraclass Correlation Coefficient (ICC). At work task level, high concordance was found between observed and interview-based scores for all the exposures examined, while at the individual level agreement was moderate. These results suggest that exposure assessment through interviews based on the OCRA check-list is a valid method, which could be used as a workstation screening tool. Practitioner summary: The study aimed to evaluate agreement between observational and interview-based exposure to ergonomic factors at work, assessed through the OCRA check-list on 32 male workers. Agreement was found at least moderate, suggesting that interview-based exposure assessed through the OCRA check-list could be used as a proxy of observations for workstation screening.

Urethroplasty with dorsal buccal mucosa graft. Is it still the method of choice in long term urethral stenosis?

The aim of our work was to evaluate the long-term changes in symptoms (median 42 months) and to analyze data for any negative predictive factors for the application of the procedure, in patients who underwent to urethroplasty with dorsal buccal mucosa graft. During the period from 2010 to 2015 27 patients were examined. Than they underwent urethroplasty using dorsal buccal mucosa graft (graft of 4 x 2.5 cm). The evaluation of symptoms has been addressed through the application of the IPSS Quality of Life Questionnaire (International Prostatic Symptoms Score) and the evaluation of urinary flow has been carried out by a comparative analysis between the pre- and post-operative uroflowmetry. As our study has shown, data obtained by the screening tests in the post-operative follow-up indicate that there is an increase in the maximum flow of urine until 1 month after surgery. The results in the long-term follow-up are different because they show a partial reduction of the maximum flow although it is maintained around an average value of 23 ml/s being still higher than the maximum flow in the pre-operative period. According to our results it follows that there is a low failure rate of the procedure after a median of 42 months. Only in patients with urethral stenosis longer than 2 cm, a lower long term success is achieved. From what we could observe, this length of the stenosis seems to be the only negative predictive factor for long-term maintenance of a good Quality of Life in patients undergoing the procedure. The results obtained from our study confirm literature data according to which, the gold standard for 2-cm long bulbar urethral stricture whose lumen is well preserved with circumferential spongiofibrosis limited to 1-2 mm is the dorsal graft urethroplasty with buccal mucosa that in our study showed success rates higher of 80% after a median follow up of 42 months and a percentage of relapse-free patients of 82.1% ( median 3.5 years).

[Inter-rater agreement on self-reported exposure to ergonomic risk factors for the upper extremities among mechanic assemblers in an automotive industry]. / Concordanza tra operatori nell'esposizione autoriferita a fattori di rischio ergonomici per l'arto superiore in addetti al montaggio meccanico di un'industria automobilistica.

OBJECTIVES: to assess reproducibility of self-reported exposure to ergonomic hazards for the upper limbs, measured through a questionnaire based on a diffused checklist for the assessment of ergonomic risk (OCRA) in a sample of mechanical assemblers of an automotive industry. DESIGN: cross-sectional study; reproducibility was assessed as interrater agreement of a composite index of ergonomic risk, estimated through the intraclass correlation coefficient (ICC). SETTING AND PARTICIPANTS: 58 mechanical assemblers, working in 29 twin areas, characterised by same work stations and tasks. MAIN OUTCOME MEASURES: composite index of ergonomic risk for the upper limbs. RESULTS: reproducibility of the ergonomic index was high in the overall sample (ICC: 0.81) and it was higher for the twin areas employing same-gender workers (ICC: 0.96), compared to those with workers of the opposite gender (ICC: 0.66). CONCLUSION: these results indicate that a questionnaire measuring with a great detail the exposure to the main ergonomic risk factors for the upper limbs, as the one based on the OCRA checklist used for this study, would allow to obtain a highly reproducible ergonomic index. If its validity against the corresponding observational checklist will be found elevated by future studies, this questionnaire may represent a useful tool for a preliminary assessment of workers' exposure to ergonomic hazards for the upper limbs.

Sexual dysfunctions after transurethral resection of the prostate (TURP): evidence from a retrospective study on 264 patients.

OBJECTIVES: Benign prostatic hyperplasia (BPH) and sexual dysfunctions are diseases with a high prevalence in aged men. Several studies have found a link between BPH and LUTS resulting from deterioration in sexual function in men aged 50 years and older for whom TURP is considered the gold standard. The impact of TURP on sexual functions still remain uncertain, nor is it clear what pathophysiological mechanism underlying the emergence of new episodes of Erectile Dysfunction (ED) following TURP in patients with normal sexual function before surgery, while retrograde ejaculation and ejaculate volume reduction represent a clear side effect; derived from BPH treatment. The aim of this study was to retrospectively evaluate the effects of transurethral resection of the prostate (TURP) on sexual function in patients operated in the period 2008-2012 at the Department of Urology of the University Hospital P. Giaccone, and at Villa Sofia-Cervello Hospital- Palermo. Secondary objective was to reconnect the sample data to interventional practice and international standards. MATERIALS AND METHODS: The retrospective longitudinal study was conducted on 264 of the 287 recruitable patients, aged between 50 and 85 years, suffering from BPH who underwent to TURP in the period 2008-2012. Telephone interviews were conducted and the International Index of Erectile Function (IIEF) was administered to assess sexual function. Patients enrolled were asked to respond to the test by referring at first to their sexual status in the period before surgery and subsequently to the state of their sexual function after treatment so as to obtain, for each patient, a pre- and post-TURP questionnaire in order to get comparisons that corresponding to reality and to avoid overestimation of the dysfunctional phenomenon. RESULTS: In the pre-TURP, the 94.32% of the sample reported being sexually active, with good erectile function in 41.3% of cases, ED mild/moderate in 51.5% and complete ED in 1, 5% of cases; good libido in 62.9% of cases, lack of libido in 31.4% of cases and absent in 5.7% of cases (the latter data corresponded to patients not sexually active); to be sexually satisfied in 29.5% of cases, slightly dissatisfied in 11, 7% of cases, moderately in 35.3% of cases, dissatisfied and very dissatisfied in 23.5% of cases (of which 17.8% sexually active and 5.7% non-active). In the post-TURP 89.4% of the sample reported being sexually active, with good erectile function in 39.1% of cases, DE mild/moderate in 46.9% and complete DE in 4% of cases; good libido in 53.8% of cases, lack of libido in 33.7% of cases and absent in 13.5% of cases (including 1.9% of sexually active and 10.6% of non-active); to be sexually satisfied in 29.5% of cases, slightly dissatisfied in 9.5% of cases, moderately in 35.3% of cases, dissatisfied and very dissatisfied in 17.8% of cases (of which 14.8% sexually active and 10.6% inactive). Retrograde ejaculation was referred in 47.8% of those sexually active after TURP (42.8% if we consider the whole sample). CONCLUSIONS: TURP had no negative impact on erectile function in contrast to ejaculatory function. Of the 109 patients with good erectile function in pre-TURP, 5.8% reported a worsening of erectile function after TURP. Among the 136 patients with ED moderate/mild pre-TURP 3.7% reported a worsening in the post-TURP, 16.2% reported an improvement, while 9.5% stopped any sexual activity. In 3.7% of the cases a complete ED was reported after TURP, while a decline of libido and sexual satisfaction was detected in all patients with worsening of sexual function. Retrograde ejaculation was observed in 48% of those sexually active after TURP. Particular attention has to be paid to the psychological aspects, both before surgery and in the postoperative period, which may become an important factor in the decline of sexual activity.

Inferior vena cava prosthetic replacement in a patient with horseshoe kidney and metastatic testicular tumor: technical considerations and review of the literature.

BACKGROUND: Seminomatous and non-seminomatous Germ Cell Tumors (GCT) of the testis are a rare cancer, with an estimated incidence of 56.3 per million white males and 10 per million black males in the United States.The association between non-seminomatous GCT and horseshoe kidney is a rare event and is seen in about 1.3% of patients requiring retroperitoneal lymph node dissection. To our knowledge, no cases have been reported in which replacement of the IVC was also necessary. CASE PRESENTATION: We report the case of a 22-year-old man with horseshoe kidney and metastatic non-seminomatous germ cell tumor involving the wall of the inferior vena cava.Following post-chemotherapy retroperitonal lymph node dissection, the inferior vena cava was replaced with an expanded polytetrafluoroethylene graft.At 2-years follow-up, the patient was in good health and the graft was patent. No clinical or diagnostic signs of renal impairment or recurrence of neoplastic disease were noted. CONCLUSION: Radical surgery is warranted in patients with non-seminomatous germ cell tumor metastasizing to the retroperitoneal lymph nodes. When vena cava replacement is required, and the situation is further complicated by horseshoe kidney, as in this case, surgical technique will rely on multidisciplinary surgical treatment planning by a team composed of urologists, vascular surgeons and oncologists.

Does the time spent in retirement improve health? An IV-Poisson assessment on the incidence of cardiovascular diseases.

In recent decades, pension reforms have been implemented to address the financial sustainability of social security systems, resulting in an increase in the retirement age. This adjustment has led to ongoing debates about the relationship between retirement and health. This study investigates the impact of time spent in retirement on the risk of cardiovascular disease (CVD) in Italy. It uses a comprehensive dataset that includes socioeconomic, health, and behavioural risk factors, which is linked to administrative hospitalisation and mortality registers. To address the potential endogeneity of retirement, we employ an instrumental variables approach embedded in a Poisson rate model. The results show that, on average, years spent in retirement have a beneficial effect on the risk of CVD for both men and women. Each additional year spent in retirement reduces the incidence of such diseases by about 17% for men and 29% for women. Stratified analyses and robustness tests show that the benefits of retirement appear to be more robust and pronounced in men and in certain groups, particularly men in manual occupations or with poor ergonomic conditions at work. These results highlight that delaying access to retirement may lead to an increased burden of CVD in the older population. In addition, the protective effect of retirement on the development of CVD among workers with poorer ergonomic conditions underlines the different impact of increasing the retirement age on different categories of workers and the need for targeted and differentiated policies to avoid hitting the more vulnerable.

Polymorphisms in the XRCC1 gene modify survival of bladder cancer patients treated with chemotherapy.

Survival of bladder cancer patients depends on several factors including disease stage and grade at diagnosis, age, health status of the patient and the applied treatment. Several studies investigated the role of DNA repair genetic variants in cancer susceptibility, but only few studies investigated their role in survival and response to chemotherapy for bladder cancer. We genotyped 28 single nucleotide polymorphisms (SNP) in DNA repair genes in 456 bladder cancer patients, reconstructed haplotypes and calculated a score for combinations of the SNPs. We estimated Hazard Ratios (adjHR) for time to death. Among patients treated with chemotherapy, variant alleles of five SNPs in the XRCC1 gene conferred better survival (rs915927 adjHR 0.55 (95%CI 0.32-0.94); rs76507 adjHR 0.48 (95%CI 0.27-0.84); rs2854501 adjHR 0.25 (95%CI 0.12-0.52); rs2854509 adjHR 0.21 (95%CI 0.09-0.46); rs3213255 adjHR 0.46 (95%CI 0.26-0.80). In this group of patients, an increasing number of variant alleles in a XRCC1 gene score were associated with a better survival (26% decrease of risk of death for each additional variant allele in XRCC1). By functional analyses we demonstrated that the previous XRCC1 SNPs confer lower DNA repair capacity. This may support the hypothesis that survival in these patients may be modulated by the different DNA repair capacity determined by genetic variants. Chemotherapy treated cancer patients bearing an increasing number of "risky" alleles in XRCC1 gene had a better survival, suggesting that a proficient DNA repair may result in resistance to therapy and shorter survival. This finding may have clinical implications for the choice of therapy.

Phosphodiesterase type 5 inhibitor treatment for erectile dysfunction in patients with end-stage renal disease receiving dialysis or after renal transplantation.

INTRODUCTION: The phosphodiesterase type 5 (PDE5) inhibitors are generally well tolerated and effective for treating erectile dysfunction (ED), including in patients with significant comorbidity. Because of this benign safety profile, investigators have used PDE5 inhibitors to treat patients with ED and severe renal disease or those who have received renal transplants. AIM: To assess safety and efficacy of PDE5 inhibitors in patients receiving dialysis or renal transplants. MAIN OUTCOME MEASURES: Erectile function as assessed by the International Index of Erectile Function (IIEF) and Global Assessment Questions; adverse events (AEs). METHODS: We reviewed published studies of PDE5 inhibitors in patients receiving dialysis or renal transplants. RESULTS: In double-blind, placebo-controlled studies in patients receiving dialysis or renal transplants, sildenafil significantly improved erectile function as assessed by the IIEF, and 75-85% of patients reported improved erectile function on Global Assessment Questions; efficacy was more variable in less well-controlled studies. In >260 patients undergoing dialysis who received sildenafil in clinical studies, there were only six reported discontinuations because of AEs (headache [N=3], headache and nausea [N=1], gastrointestinal [N=1], and symptomatic blood pressure decrease [N=1]). In approximately 400 patients with renal transplants who received sildenafil, only three patients discontinued because of AEs. Vardenafil improved IIEF scores of up to 82% of renal transplant recipients in randomized, controlled studies (N=59, total), with no reported discontinuations because of AEs. Limited data also suggest benefit with tadalafil. CONCLUSIONS: ED is common in patients undergoing renal dialysis or postrenal transplant and substantially affects patient quality of life. Sildenafil and vardenafil appear to be efficacious and well tolerated in patients receiving renal dialysis or transplant.

Effect of Different Methods to Synthesize Polyol-Grafted-Cellulose Nanocrystals as Inter-Active Filler in Bio-Based Polyurethane Foams.

Currently, the scientific community has spent a lot of effort in developing "green" and environmentally friendly processes and products, due the contemporary problems connected to pollution and climate change. Cellulose nanocrystals (CNCs) are at the forefront of current research due to their multifunctional characteristics of biocompatibility, high mechanical properties, specific surface area, tunable surface chemistry and renewability. However, despite these many advantages, their inherent hydrophilicity poses a substantial challenge for the application of CNCs as a reinforcing filler in polymers, as it complicates their dispersion in hydrophobic polymeric matrices, such as polyurethane foams, often resulting in aggregate structures that compromise their properties. The manipulation and fine-tuning of the interfacial properties of CNCs is a crucial step to exploit their full potential in the development of new materials. In this respect, starting from an aqueous dispersion of CNCs, two different strategies were used to properly functionalize fillers: (i) freeze drying, solubilization in DMA/LiCl media and subsequent grafting with bio-based polyols; (ii) solvent exchange and subsequent grafting with bio-based polyols. The influence of the two functionalization methods on the chemical and thermal properties of CNCs was examined. In both cases, the role of the two bio-based polyols on filler functionalization was elucidated. Afterwards, the functionalized CNCs were used at 5 wt% to produce bio-based composite polyurethane foams and their effect on the morphological, thermal and mechanical properties was examined. It was found that CNCs modified through freeze drying, solubilization and bio-polyols grafting exhibited remarkably higher thermal stability (i.e., degradation stages > 100 °C) with respect to the unmodified freeze dried-CNCs. In addition, the use of the two grafting bio-polyols influenced the functionalization process, corresponding to different amount of grafted-silane-polyol and leading to different chemico-physical characteristics of the obtained CNCs. This was translated to higher thermal stability as well as improved functional and mechanical performances of the produced bio-based composite PUR foams with respect of the unmodified CNCs-composite ones (the best case attained compressive strength values three times more). Solvent exchange route slightly improved the thermal stability of the obtained CNCs; however; the so-obtained CNCs could not be properly dispersed within the polyurethane matrix, due to filler aggregation.

Prognostic factors in a large multi-institutional series of papillary renal cell carcinoma.

OBJECTIVES: To investigate cancer-related outcomes and prognostic factors of papillary renal cell carcinoma (pRCC) in a large multicentre data set. Oncological outcome and prognostic factors of pRCC have been limitedly evaluated in comparison with the most common RCC subtype, clear cell RCC. PATIENTS AND METHODS: From a multicentre retrospective database, including 5463 patients who were surgically treated for RCC at 16 Italian academic centres between 1995 and 2007, 577 patients with pRCC were identified. Univariable and multivariable Cox regression models were performed to identify prognostic factors predictive of recurrence-free survival (RFS) and cancer-specific survival (CSS) after surgery. RESULTS: At a median (interquartile range) follow-up of 39.2 (21.7-72) months, 81 (14%) patients had experienced disease progression and 63 (11%) patients had died from disease; the 5-year RFS estimate was 85.5%. In multivariable analysis, pathological N stage (pooled P < 0.001), M stage (hazard ratio, 2.9; P= 0.007) and Fuhrman nuclear grade (pooled P= 0.039) were all independent predictors of RFS; the 5-year CSS estimate was 87.9%. In Cox multivariable analysis, an independent predictive role was reconfirmed for mode of presentation (pooled P= 0.038), pathological N stage (pooled P < 0.001), M stage (hazard ratio, 2.4; P= 0.049) and Fuhrman nuclear grade (pooled P= 0.037). CONCLUSIONS: Patients with pRCC have a low risk of tumour recurrence and cancer-related death after surgery. Fuhrman nuclear grade was found to be a stronger predictor of both RFS and CSS, whereas only a non-statistically significant trend was found for the 2009 pathological T stage.

A new, innovative, lengthening surgical procedure for Peyronie's disease by penile prosthesis implantation with double dorsal-ventral patch graft: the "sliding technique".

INTRODUCTION: Peyronie's disease is the result of the formation of fibrous plaques in the tunica albuginea of the penis; typical presentations of the disease are represented by pain during erection, erectile dysfunction, and penile deformities, such as curvature, narrowing, and penile shortening. The most complex treatment is related to penile shortening. AIM: To find a safe procedure in penile shortening due to Peyronie's disease providing a satisfactory lengthening, allowing an early stabilization of the penis, and preventing axial tension on the neurovascular bundles during dilation. METHODS: We describe a new lengthening surgical procedure based on a ventro-dorsal incision of the tunica albuginea, penile prosthesis implantation, and double dorsal-ventral patch grafting with porcine small intestinal submucosa. Three patients, affected by Peyronie's disease with penile shortening and erectile dysfunction, underwent this procedure with approval of our local ethical committee. We evaluated the penis lengthening, intraoperative and postoperative complications, patient's preoperative and postoperative sexual life satisfaction (International Index of Erectile Function [IIEF] questionnaire). RESULTS: The average operative time was 2 hours and 50 minutes. No major intraoperative nor postoperative complications occurred. No significant bleedings were recorded. Patients were discharged after 48-72 hours. The average increase in length obtained was 3.2 cm. All patients resumed sexual intercourses with satisfaction; no significant loss of sensitivity or any sign of vascular distress of the glans was recorded. The follow-up is 13 months. The average IIEF score is 60. CONCLUSIONS: The lengthening of the penis by a double dorsal-ventral patch graft is an innovative procedure that is based on current techniques of plaque incision and grafting, and that can easily resolve severe shortening of the penis due to Peyronie's disease. In the cases presented, this procedure resulted easily, effectively, and safely. Nevertheless, the technique proposed in this article shall be validated through prospective studies with larger samples.

Evidence of abnormal tyrosine phosphorylated proteins in the urine of patients with bladder cancer: the road toward a new diagnostic tool?

PURPOSE: Since changes in protein phosphorylation are a common feature of cancer cells, we analyzed phosphoproteins in the tissue and urine of patients with bladder cancer and assessed the diagnostic relevance of abnormally phosphorylated proteins as tumor markers. MATERIALS AND METHODS: Enrolled in this study were 66 patients and 82 healthy volunteers. From the first 14 patients with bladder cancer we obtained samples of malignant and normal bladder tissue. All patients and volunteers provided a urine sample. Protein extracts of tissue specimens were separated by 2-dimensional gel electrophoresis for comparative analysis of neoplastic and normal tissue. Phosphoproteins were studied by Western blot and characterized by mass spectrometry. Urine samples were analyzed by 1-dimensional gel electrophoresis. Phosphoproteins were measured by affinity dot blotting. RESULTS: Profound changes in the pattern of protein tyrosine phosphorylation were consistently, reproducibly observed in bladder cancer tissues. A total of 24 phosphorylated proteins were differentially expressed in cancer tissue and identified by mass spectrometry. Phosphoproteins were fairly stable in urine samples, leading to accumulation. Urinary tyrosine phosphoproteins showed the most remarkable changes in patients with cancer with an approximately 5-fold increase compared to levels in healthy controls. CONCLUSIONS: To our knowledge we investigated for the first time the diagnostic potential of tissue and urinary tyrosine phosphoproteins for bladder carcinoma. Results indicate that phosphorylated proteins may represent a new, valuable class of urinary biomarkers for bladder cancer.

Simple enucleation is equivalent to traditional partial nephrectomy for renal cell carcinoma: results of a nonrandomized, retrospective, comparative study.

PURPOSE: The excision of the renal tumor with a substantial margin of healthy parenchyma is considered the gold standard technique for partial nephrectomy. However, simple enucleation showed excellent results in some retrospective series. We compared the oncologic outcomes after standard partial nephrectomy and simple enucleation. MATERIALS AND METHODS: We retrospectively analyzed 982 patients who underwent standard partial nephrectomy and 537 who had simple enucleation for localized renal cell carcinoma at 16 academic centers between 1997 and 2007. Local recurrence, cancer specific survival and progression-free survival were the main outcomes of this study. The Kaplan-Meier method was used to calculate survival functions and differences were assessed with the log rank statistic. Univariable and multivariable Cox regression models addressed progression-free survival and cancer specific survival. RESULTS: Median followup of the patients undergoing traditional partial nephrectomy and simple enucleation was 51 ± 37.8 and 54.4 ± 36 months, respectively (p = 0.08). The 5 and 10-year progression-free survival estimates were 88.9 and 82% after standard partial nephrectomy, and 91.4% and 90.8% after simple enucleation (p = 0.09). The 5 and 10-year cancer specific survival estimates were 93.9% and 91.6% after standard partial nephrectomy, and 94.3% and 93.2% after simple enucleation (p = 0.94). On multivariable analysis the adopted nephron sparing surgery technique was not an independent predictor of progression-free survival (HR 0.8, p = 0.55) and cancer specific survival (HR 0.7, p = 0.53) when adjusted for the effect of the other covariates. CONCLUSIONS: To our knowledge this is the first multicenter, comparative study showing oncologic equivalence of standard partial nephrectomy and simple enucleation.

Highly specific detection of prostate-specific antigen-positive cells in the blood of patients with prostate cancer or benign prostatic hyperplasia, using a real-time reverse-transcription-polymerase chain reaction method with improved sensitivity.

OBJECTIVE: To assess the presence of circulating prostate-specific antigen (PSA)-expressing cells in patients with prostate cancer or benign prostatic hyperplasia (BPH), and to determine their diagnostic usefulness using a highly sensitive quantitative real-time reverse-transcription polymerase chain reaction (qRT-PCR) method. PATIENTS, SUBJECTS AND METHODS: Venous blood samples were obtained from 175 patients with prostate cancer (12 metastatic and 163 not metastatic), 49 with BPH, and 50 healthy volunteers. To improve the specificity and sensitivity of the qRT-PCR three innovative features were combined; a primer overlapping two adjacent exons to inhibit nonspecific amplification; a no-end-point first round amplification to increase the sensitivity; and a target-specific primer for the RT phase to increase the specificity. RESULTS: The sensitivity of the method was 1 cell/mL of blood and the interassay coefficient of variation was 10.5%. None of the healthy subjects tested positively, while 9% of those with prostatic cancer and 14% with BPH had PSA-positive cells in the blood. There was a positive association between a positive test and the National Comprehensive Cancer Network classification in the patients with newly diagnosed prostate cancer (P = 0.022). There were no additional statistically significant associations. CONCLUSION: Our results strongly indicate that although there were no false-positive results and the sensitivity of the method was increased to maximal levels, a low frequency of positive results in patients with prostatic cancer and a high frequency of positive results in those with BPH seems to discourage the use of PSA-positive circulating cells in the search for a clinical diagnosis of prostate cancer.

Postoperative complications and 90-day mortality in radical cystectomy in high-risk patients: A monocentric retrospective observational study.

AIM: Assessing the incidence of immediate postoperative complications and 90-day mortality in high-risk patients who have undergone radical cystectomy; evaluating the correlation between preoperative conditions and surgery outcomes. MATERIALS AND METHODS: This is a monocentric retrospective observational study in which data of 65 patients have been analyzed. High-risk criteria: (a) Age ≥75 years, (b) obesity, (c) age-adjusted Charlson Comorbidity Index ≥8, (d) anemic status, and (e) pT ≥3. More than 50% of patients had two or more "high-risk" indicators. Postoperative complications were assessed through Clavien-Dindo classification. RESULTS: Average age of patients was 70.4 years, average age-adjusted Charlson Comorbidity Index was 5.8, and average body mass index was 27.5. In 28% of patients, no complications arose, while in 46% grades I-II complications according to Clavien-Dindo occurred, in 23% grades III-IV complications occurred, and in 3% of the patients, death arose in the immediate postoperative period (grade V). Overall, 90-day mortality rate after surgery was 12.3%. The age ≥75 years and an age-adjusted Charlson Comorbidity Index score ≥8 have shown to be risk factors for the onset of severe complications (odds ratio = 3.54, p = 0.028 and odds ratio = 4.7, p = 0.026), while preoperative anemic status was a risk factor for complications in general (odds ratio = 4.1, p = 0.015). No analyzed parameter was a predictor of 90-day mortality ( p > 0.05). CONCLUSION: Immediate postoperative complications and 90-day mortality in radical cystectomy in high-risk patients remain significant, but still in line with the data in the literature on comparable populations. Some of the preoperative parameters were able to predict the outcomes of the intervention with regard to the onset of complications but not to the 90-day mortality.

Urology Residency Training in Italy: Results of the First National Survey.

BACKGROUND: Numerous surveys have been performed to determine the competence and the confidence of residents. However, there is no data available on the condition of Italian residents in urology. OBJECTIVE: To investigate the status of training among Italian residents in urology regarding scientific activity and surgical exposure. DESIGN, SETTING, AND PARTICIPANTS: A web-based survey that included 445 residents from all of the 25 Italian Residency Programmes was conducted between September 2015 and November 2015. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: The main outcomes were represented by scientific activity, involvement in surgical procedures, and overall satisfaction. RESULTS AND LIMITATIONS: In total, 324 out of 445 (72.8%) residents completed the survey. Overall, 104 (32%) residents had not published any scientific manuscripts, 148 (46%) published ≤5, 38 (12%) ≤10, 26 (8%) ≤15, four (1%) ≤20, and four (1%) >20 manuscripts, respectively. We did not observe any differences when residents were stratified by sex (p=0.5). Stent positioning (45.7%), extracorporeal shock wave lithotripsy (30.9%), transurethral resection of bladder tumor (33.0%), hydrocelectomy (24.7%), varicocelectomy (17%), ureterolithotripsy (14.5%), and orchiectomy (12.3%) were the surgical procedures more frequently performed by residents. Overall, 272 residents (84%) expressed a good satisfaction for urology specialty, while 178 (54.9%) expressed a good satisfaction for their own residency programme. We observed a statistically decreased trend for good satisfaction for urology specialty according to the postgraduate year (p=0.02). CONCLUSIONS: Italian Urology Residency Programmes feature some heavy limitations regarding scientific activity and surgical exposure. Nonetheless, satisfaction rate for urology specialty remains high. Further improvements in Residency Programmes should be made in order to align our schools to others that are actually more challenging. PATIENT SUMMARY: In this web-based survey, Italian residents in urology showed limited scientific productivity and low involvement in surgical procedures. Satisfaction for urology specialty remains high, demonstrating continuous interest in this field of study from residents.
