Vaccination of healthcare workers (HCWs) is a crucial element to overcome the COVID-19 pandemic. The aim of this survey was to assess attitudes, sources of information and practices among Italian Healthcare workers (HCWs) in relation to COVID-19 vaccination. Methods: From 19 February to 23 April 2021, an anonymous voluntary questionnaire was sent to the mailing list of the main National Health Service structures. Data were collected through the SurveyMonkey platform. Results: A total of 2137 HCWs answered. Hesitancy towards COVID-19 vaccination was more frequent in females, in those with lower concern about COVID-19, and in nurses, auxiliary nurses (AN) and healthcare assistants. Hesitant professionals were more likely to not recommend vaccination to their patients or relatives, while a high concern about COVID-19 was related to an increased rate of recommendation to family members. HCWs were mostly in favor of mandatory vaccination (61.22%). Female sex, a lower education level, greater hesitancy and refusal to adhere to flu vaccination campaigns were predictors influencing the aversion to mandatory vaccination. All categories of HCWs referred mainly to institutional sources of information, while scientific literature was more used by professionals working in the northern regions of Italy and in infection control, infectious diseases, emergencies and critical areas. HCWs working in south-central regions, nurses, AN, healthcare technicians, administrators and HCWs with a lower education level were more likely to rely on internet, television, newspapers, and the opinions of family and friends. Conclusions: Communication in support of COVID-19 immunization campaigns should consider the differences between the various HCWs professional categories in order to efficiently reach all professionals, including the most hesitant ones.

Thyroid autoimmunity is the most prevalent autoimmune state that affects up to 5-20% of women during the age of fertility. Prevalence of thyroid autoimmunity is significantly higher among infertile women, especially when the cause of infertility is endometriosis or polycystic ovary syndrome. Presence of thyroid autoimmunity does not interfere with normal embryo implantation and have been observed comparable pregnancy rates after assisted reproduction techniques in patients with or without thyroid autoimmunity. Instead, the risk of early miscarriage is substantially raised with the presence of thyroid autoimmunity, even if there was a condition of euthyroidism before pregnancy. Furthermore the controlled ovarian hyperstimulation, used as preparation for assisted reproduction techniques, can severely impair thyroid function increasing circulating estrogen levels. Systematic screening for thyroid disorders in women with a female cause of infertility is controversial but might be important to detect thyroid autoimmunity before to use assisted reproduction techniques and to follow-up these parameters in these patients after controlled ovarian hyperstimulation and during pregnancy.

Background Simulation in laparoscopic surgery is nowadays recognized as a valid instrument for learning and training surgeons in different procedures. However, its role as evaluation test and self-assessment tool to verify basic surgical skills is still under discussion. Methods Thirty-three residents in obstetrics and gynecology at University of Pisa, Italy were recruited, and they received a simulation program consisting of 5 tasks. They had to perform basic laparoscopic surgery maneuvers as creating pneumoperitoneum, positioning trocars under vision, demonstrating the appropriate use of dominant and non-dominant hand and making single stitch and knot. They were evaluated with a modified OSATs scale. Results Senior trainees had better score than junior trainees (p value< 0,005) and after different sessions of simulation scores of both groups significantly improved (p < 0,001), especially for the junior group. All the trainees reported self-assessments that matched with the evaluation of external observers demonstrating the importance of simulation also as auto-evaluation test. Conclusions In this study, we demonstrated the role of simulation as powerful tool to evaluate and to self-assess surgical technical skills and to improve own capacities, with the use of a modified OSATs scale adapted to specific exercises.

Controlled ovarian stimulation (COH) in PCOS is a challenge for fertility expert both ovarian hyperstimulation syndrome (OHSS) and oocytes immaturity are the two major complication. Ovarian response to COH vary widely among POCS patients and while some patients are more likely to show resistance to COH, other experienced an exaggerated response. The aim of our study is to investigate a possible correlation between PCOS phenotypes and the variety of ovarian response to COH and ART outcomes in patients with different PCOS phenotypes. We retrospectively analyzed a total of 71 cycles performed in 44 PCOS infertile patients attending ART at Centre of Infertility and Assisted Reproduction of Pisa University between January 2013 and January 2016. Patientsundergoing IVF with GnRH-antagonist protocol and 150-225 UI/days of recombinant FSH; triggering was carried out using 250 mg of recombinant hCG or a GnRH analogous on the basis of the risk to OHSS. We observed that Phenotype B had a tendency to have a greater doses of gonadotropins used respect to all phenotypes. Phenotype A group showed a greater serum estrogen levels compared to all phenotypes groups, a greater number of follicles of diameter between 8-12 mm found by ultrasound on the day of triggering and a greater mean number of freeze embryo. Additionally serum AMH and antral follicles count (AFC) follow the same trend in the different phenotypes ad they were significantly higher in phenotype A and in phenotype D. In conclusion this study shows that the features of PCOS phenotypes reflect the variety of ovarian response to COH as well as the risks to develop OHSS. Serum AMH and AFC are related to the degree of ovulatory dysfunction making these 'added values' in identifying the different PCOS phenotypes. Phenotype A seems to be the phenotype with the higher risk to develop OHSS and the use of GnRH as a trigger seems to improve oocyte quality. To classify PCOS phenotype at diagnosis might help clinicians to identify patients at greater risk of OHSS, customize therapy and subsequently plan the trigger agent.

Purpose Endometriosis may influence different aspects of reproductive physiology including folliculogenesis, ovulation, embryo quality, and fertilization. Recent data demonstrate that patients with endometriosis-associated infertility undergoing in vitro fertilization (IVF) have a reduction of pregnancy rates compared to women with other indications for IVF. The aim of the study is to evaluate the outcomes of IVF after controlled ovarian hyperstimulation (COH) with GnRH antagonist (GnRH-ant) or GnRH agonist (GnRH-a) in severe endometriosis patients. Methods A total of 101 patients with severe endometriosis undergoing IVF cycles were retrospectively enrolled into two groups in relation to hypothalamic inhibition before COH, obtained respectively with leuprorelin and cetrorelix. We evaluated characteristics of COH and clinical outcomes (overall pregnancy rate, implantation rate, spontaneous miscarriages, ectopic pregnancies, and clinical pregnancy rates). Results The group treated with GnRH-ant presented a similar number of MII oocytes and good quality embryos while using a lower amount of gonadotropins. Outcomes of COH with both GnRH-ant and GnRH-a were similar in patients with stage III-IV endometriosis. The number of retrieved oocytes, the number of obtained embryos, the implantation rates, and the clinical pregnancy rates were similar with GnRH-ant and GnRH-a protocols. Conclusions Considering the pregnancy outcomes, COH with both GnRH-ant and GnRH-a protocols do not present statistical differences in patients with severe endometriosis, but the GnRH-ant protocol could be more convenient in term of gonadotropins amount and patient discomfort.

The improvement of reproductive parameters after DHEA supplementation in poor responders may be explained through the effect that this pro-hormone exerts on follicular microenvironment.
