Exploring the Impact of Controlled Ovarian Stimulation and Non-Invasive Oocyte Assessment in ART Treatments.

Invasive and noninvasive features are normally applied to select developmentally competent oocytes and embryos that can increase the take-home baby rates in assisted reproductive technology. The noninvasive approach mainly applied to determine oocyte and embryo competence has been, since the early days of IVF, the morphological evaluation of the mature cumulus-oocyte complex at the time of pickup, first polar body, zona pellucida thickness, perivitelline space and cytoplasm appearance. Morphological evaluation of oocyte quality is one of the options used to predict successful fertilization, early embryo development, uterine implantation and the capacity of an embryo to generate a healthy pregnancy to term. Thus, this paper aims to provide an analytical revision of the current literature relating to the correlation between ovarian stimulation procedures and oocyte/embryo quality. In detail, several aspects of oocyte quality such as morphological features, oocyte competence and its surrounding environment will be discussed. In addition, the main noninvasive features as well as novel approaches to biomechanical parameters of oocytes that might be correlated with the competence of embryos to produce a healthy pregnancy and live birth will be illustrated

The role of resveratrol in liver disease: A comprehensive review from in vitro to clinical trials

Many studies have shown that resveratrol has a lot of therapeutic effects on liver disorders. Its administration can significantly increase the survival rate after liver transplantation, reduce fat deposition and ischemia-induced necrosis and apoptosis in Wistar rats. Resveratrol can provide Liver protection against chemical, cholestatic, and alcohol-mediated damage. It can improve glucose metabolism and lipid profile, reduce liver fibrosis, and steatosis. Additionally, it is capable of altering the fatty acid composition of the liver cells. Resveratrol may be a potential treatment option for the management of non-alcoholic fatty liver disease (NAFLD) due to its anti-inflammatory, antioxidant, and calorie-restricting effects. There are also studies that have evaluated the effect of resveratrol on lipid and liver enzyme profiles among patients with metabolic syndrome (MetS) and related disorders. Based on the extent of liver disease worldwide and the need to find new treatment possibilities, this review critically examines current in vitro and in vivo preclinical studies and human clinical studies related to liver protection

Erectile and sexual dysfunction in male and female patients with celiac disease: A cross-sectional observational study

Introduction: Sexual function is often impaired in patients with chronic illnesses. Several patients with chronic gastrointestinal and liver disorders have been shown to suffer from sexual dysfunction, and celiac disease is a highly prevalent gastroenterological disorder. Aim: The aim of this study was to investigate the sexual function incidence and the risk factors for sexual dysfunction in both male and female celiac disease patients. Methods: Two hundred and eighty-four patients (170 females, 114 males) participated in this cross-sectional observational study in an anonymous manner. Female sexual function was assessed through the Female Sexual Function Index questionnaire. Male sexual function was assessed through the International Index of Erectile Function-5 questionnaire. Clinical-demographic variables were recorded. We investigated differences in the patient-reported outcomes among the different subgroups and whether there were clinical-demographic predictors of sexual dysfunction in our setting. Main outcome measures: Prevalence and assessment of sexual dysfunction in celiac disease patients. Results: In the female group, 85 subjects (50%) had a total score compatible with sexual dysfunction: 43 (61.42%) showed low desire, 79 (46.47%) showed arousal disorder, 66 (38.82%) lubrication disorder, and 84 (49.41%) inability of obtaining an orgasm. Also, a large proportion of our female patients, 161 (94.70%), showed sexual discomfort during intercourse. In the male group, 79 patients (62.2%) showed scores compatible with normal erectile function, eight (7.01%) had mild erectile dysfunction, 24 (21.05%) mild to moderate erectile dysfunction, and three (2.63%) presented severe erectile dysfunction. Altered body mass index was significantly associated with sexual dysfunction both in male and female patients. Early age at diagnosis was a significant predictor of sexual dysfunction in male celiac disease patients. Conclusions: A significant proportion of celiac disease patients present sexual dysfunction. Early age at diagnosis and high body mass index seem to predict sexual dysfunction in this clinical setting. Assessment of sexual function should be part of the initial evaluation of celiac disease patients in order to establish a prompt diagnosis and early treatment

Surgical activity in the COVID-19 era. Trend of slowdown from a multicentre observational study

COVID-19 outbreak represented an unprecedented event that led to a redefinition of health care systems worldwide. The impact of the emergency required a deviation of the care toward the assistance to COVID-19 patients, with reduction of resources for elective activities, including surgery. We aim to report the decrease of urological surgical activity during the first weeks from the beginning of the pandemic, aiming to highlight the prioritization we applied to select patients for surgery

The dramatic COVID-19 outbreak in italy is responsible of a huge drop in urological surgical activity: A multicenter observational study

OBJECTIVE: Italy is facing the COVID-19 outbreak with an abrupt reorganization of its national health-system, in order to augment care provision to symptomatic patients. The sudden shift of personnel and resources towards COVID-19 care has led to the reduction of surgery, with possible severe drawbacks. The aim of the study is to describe the trend in surgical volume in urology, in Italy. MATERIALS AND METHODS: Thirty-three urological units with physicians affiliated to the AGILE consortium were involved in a survey. Urologists were asked to report the amount of surgical elective procedures week-by-week, from the beginning of the emergency to the following month. RESULTS: The 33 hospitals involved in the study account, globally, for 22,945 beds and are distributed in 13/20 Italian regions. Before the outbreak, the involved urology units performed an overall amount of 1,213 procedures per week, half of which were oncological. One month later, the amount of surgery declined by 78%. Lombardy, the first region with positive-cases, experienced a 94% reduction. The decrease in oncological and non-oncological surgical activity was 35,9% and 89%, respectively. The trend of the decline showed a delay of roughly 2 weeks for the other regions. CONCLUSION: Italy, the country with the highest fatality rate from COVID-19, is experiencing a sudden decline in surgical activity. It is inversely related to the increase in COVID-19 care, with potential harm particularly in the oncological field. The Italian experience can be helpful for future surgical pre-planning in other countries not so hardly hit by the disease yet

Impact of gastrointestinal side effects on patients’ reported quality of life trajectories after radiotherapy for prostate cancer: Data from the prospective, observational pros-it CNR study

Radiotherapy (RT) represents an important therapeutic option for the treatment of localized prostate cancer. The aim of the current study is to examine trajectories in patients’ reported quality of life (QoL) aspects related to bowel function and bother, considering data from the PROState cancer monitoring in ITaly from the National Research Council (Pros-IT CNR) study, analyzed with growth mixture models. Data for patients who underwent RT, either associated or not associated with androgen deprivation therapy, were considered. QoL outcomes were assessed over a 2-year period from the diagnosis, using the Italian version of the University of California Los Angeles-Prostate Cancer Index (Italian-UCLA-PCI). Three trajectories were identified for the bowel function; having three or more comorbidities and the use of 3D-CRT technique for RT were associated with the worst trajectory (OR = 3.80, 95% CI 2.04–7.08; OR = 2.17, 95% CI 1.22–3.87, respectively). Two trajectories were identified for the bowel bother scores; diabetes and the non-Image guided RT method were associated with being in the worst bowel bother trajectory group (OR = 1.69, 95% CI 1.06–2.67; OR = 2.57, 95% CI 1.70–3.86, respectively). The findings from this study suggest that the absence of comorbidities and the use of intensity modulated RT techniques with image guidance are related with a better tolerance to RT in terms of bowel side effects

Disease-specific and general health-related quality of life in newly diagnosed prostate cancer patients: The Pros-IT CNR study

Background: The National Research Council (CNR) prostate cancer monitoring project in Italy (Pros-IT CNR) is an observational, prospective, ongoing, multicentre study aiming to monitor a sample of Italian males diagnosed as new cases of prostate cancer. The present study aims to present data on the quality of life at time prostate cancer is diagnosed. Methods: One thousand seven hundred five patients were enrolled. Quality of life is evaluated at the time cancer was diagnosed and at subsequent assessments via the Italian version of the University of California Los Angeles-Prostate Cancer Index (UCLA-PCI) and the Short Form Health Survey (SF-12). Results: At diagnosis, lower scores on the physical component of the SF-12 were associated to older ages, obesity and the presence of 3+ moderate/severe comorbidities. Lower scores on the mental component were associated to younger ages, the presence of 3+ moderate/severe comorbidities and a T-score higher than one. Urinary and bowel functions according to UCLA-PCI were generally good. Almost 5% of the sample reported using at least one safety pad daily to control urinary loss; less than 3% reported moderate/severe problems attributable to bowel functions, and sexual function was a moderate/severe problem for 26.7%. Diabetes, 3+ moderate/severe comorbidities, T2 or T3-T4 categories and a Gleason score of eight or more were significantly associated with lower sexual function scores at diagnosis. Conclusions: Data collected by the Pros-IT CNR study have clarified the baseline status of newly diagnosed prostate cancer patients. A comprehensive assessment of quality of life will allow to objectively evaluate outcomes of different profile of care

Clinical utility of freeze-all approach in ART treatment: a mini-review

A significant proportion of couples at reproductive age rely on assisted reproductive technology to overcome infertility. In vitro fertilisation (IVF) involves typically the use of exogenous gonadotropins to stimulate the ovary to produce oocytes, which are collected surgically. After fertilization by conventional IVF or intracytoplasmic sperm injection (ICSI), embryos are cultured in the embryology laboratory for a few days before being replaced into the uterus (fresh embryo transfer). Spare embryos can be vitrified and stored in liquid nitrogen to be transferred in a subsequent cycle. Over the years, concerns have arisen about possible adverse outcomes of transferring embryos back to the uterus immediately after controlled ovarian stimulation (COS) as regards to obstetrical and perinatal outcomes. It has been suggested that high hormonal levels during COS could create a relatively hostile environment for embryo implantation whilst increasing the risk of ovarian hyperstimulation syndrome (OHSS). With the remarkable improvement of vitrification as an alternative to the slow-freezing technique for human embryos, a new strategy the so-called “freeze-all” (FA) or “elective frozen embryo transfer” (eFET) was introduced. This approach involves COS, followed by the elective cryopreservation of the entire cohort of viable embryos to be transferred to the uterus in subsequent cycles in a possibly more physiological environment, thus avoiding the supra-physiologic hormonal levels observed during COS. The initial reports suggested that this policy could lead to improved pregnancy rates and reduced perinatal complications, which resulted in a steady increase and widespread use of FA globally. However, as data accumulated, it became clear that the use of FA to unselected couples undergoing ART offered no additional benefits over the conventional approach. Nonetheless, current evidence based on randomized controlled trials and observational studies indicates that FA might be justified in selected clinical scenarios, such as those involving the risk of OHSS. By contrast, there is a lack of evidence to support the FA policy for other indications, such as implantation failure or high progesterone levels on the trigger day. This review summarizes the clinical effectiveness of FA with the main focus on the health of offspring9291

Option Pricing under Multifractional Process and Long-Range Dependence

We introduced a new method to compute the European Call (and Put) Option price under the assumption of multifractional Brownian motion (mBm). The reason why we need a procedure for estimating the Option price is due to the absence of a closed formula for this process. To compute the Option price, we first simulated the logarithmic price under mBm and, by using a discount factor, we computed the option's pay-off. Then, we fitted the best probability distribution associated to the discounted pay-off, computing the European Call Option price as its average
