BackgroundHealthcare workers (HCW) are at increased risk of being infected with SARS-CoV-2, yet limited information is available on risk factors of infection.MethodsWe pooled data on occupational surveillance of 10,654 HCW who were tested for SARS-CoV-2 infection in six Italian centers. Information was available on demographics, job title, department of employment, source of exposure, use of personal protective equipment (PPE), and COVID-19-related symptoms. We fitted multivariable logistic regression models to calculate odds ratios (OR) and 95% confidence intervals (CI).FindingsThe prevalence of infection varied across centers and ranged from 3.0% to 22.0%, being strongly correlated with that of the respective areas. Women were at lower risk of infection compared to men. Fever, cough, dyspnea and malaise were the symptoms most strongly associated with infection, together with anosmia and ageusia. No differences in the risk of infection were detected between job titles, or working in a COVID-19 designated department. Reported contact with a patient inside or outside the workplace was a risk factor. Use of a mask was strongly protective against risk of infection as was use of gloves. The use of a mask by the source of exposure (patient or colleague) had an independent effect in reducing infection risk.

This retrospective study assessed several clinical, case history and functional parameters to investigate benign paroxysmal positional vertigo (BPPV) in patients with migraine.Two groups of patients were compared: those affected by BPPV and migraine (group A), as defined by International Headache Society criteria, and those with BPPV without migraine or with another form of headache (group B). The following parameters were investigated: onset of BPPV, recovery time, residual dizziness, recurrence of BPPV, atypical eye movement patterns and Meniere-like vertigo in the inter-critical BPPV period.Mean age at BPPV onset was 39 years +/- 9.2 in Group A and 53 years +/- 7.3 in Group B (p = 0.00). No significant difference emerged in the number of manoeuvres needed to achieve recovery (Group A: 1.7 +/- 0.94; Group B: 1.9 +/- 0.89; p0.05). Highly recurrent BPPV (at least 4 documented episodes) was observed in 15 patients from group A (19.4%) and in 8 patients from group B (7.3%). Atypical eyes movements and Meniere-like vertigo were more frequent in migraineurs with highly recurrent BPPV (Chi square = 5.76; p0.016).A high prevalence of BPPV and earlier onset in migraine are the main findings of this study. There is a higher incidence of a range of neurotological patterns in the intervals between BPPV episodes in migraineurs with recurrent vertigo. No direct pathophysiological link between migraine and BPPV has yet been established; comorbidity seems to affect clinical features in a sub-population of patients and make BPPV more debilitating.

Objectives Serum anti-dsDNA and anti-nucleosome IgGs have been proposed as signatures for SLE and LN in limited numbers of patients. We sought to show higher sensitivity and specificity of the same antibodies with the IgG2 isotype and included IgG2 antibodies vs specific intracellular antigens in the analysis. Methods A total of 1052 SLE patients with (n = 479) and without (n = 573) LN, recruited at different times from the beginning of symptoms, were included in the study. Patients with primary APS (PAPS, n = 24), RA (RA, n = 24) and UCTD (UCTD, n = 96) were analysed for comparison. Anti-nucleosome (dsDNA, Histone2A, Histone3), anti-intracellular antigens (ENO1), anti-annexin A1 and anti-C1q IgG2 were determined by non-commercial techniques. Results The presence in the serum of the IgG2 panel was highly discriminatory for SLE/LN vs healthy subjects. Serum levels of anti-dsDNA and anti-C1q IgG2 were more sensitive than those of IgGs (Farr radioimmunoassay/commercial assays) in identifying SLE patients at low–medium increments. Of more importance, serum positivity for anti-ENO1 and anti-H2A IgG2 discriminated between LN and SLE (ROC T0–12 months), and high levels at T0–1 month were detected in 63% and 67%, respectively, of LN, vs 3% and 3%, respectively, of SLE patients; serum positivity for each of these was correlated with high SLEDAI values. Minor differences existed between LN/SLE and the other rheumatologic conditions. Conclusion Nephritogenic IgG2 antibodies represent a specific signature of SLE/LN, with a few overlaps with other rheumatologic conditions. High levels of anti-ENO1 and anti-H2A IgG2 correlated with SLE activity indexes and were discriminatory between SLE patients limited to the renal complication and other SLE patients.

Objectives Circulating anti-ENO1 and anti-H2A IgG2 have been identified as specific signatures of LN in a cross-over approach. We sought to show whether the same antibodies identify selected population of patients with LN with potentially different clinical outcomes. Methods Here we report the prospective analysis over 36 months of circulating IgG2 levels in patients with newly diagnosed LN (n=91) and SLE (n=31) and in other patients with SLE recruited within 2 years from diagnosis (n=99). Anti-podocyte (ENO1), anti-nucleosome (DNA, histone 2 A, histone 3) and anti-circulating proteins (C1q, AnnexinA1-ANXA1) IgG2 antibodies were determined by home-made techniques. Results LN patients were the main focus of the study. Anti-ENO1, anti-H2A and anti-ANXA1 IgG2 decreased in parallel to proteinuria and normalized within 12 months in the majority of patients while anti-dsDNA IgG2 remained high over the 36 months. Anti-ENO1 and anti-H2A had the highest association with proteinuria (Heat Map) and identified the highest number of patients with high proteinuria (68% and 71% respectively) and/or with reduced estimated glomerula filtration rate (eGFR) (58% for both antibodies) compared with 23% and 17% of anti-dsDNA (agreement analysis). Anti-ENO1 positive LN patients had higher proteinuria than negative patients at T0 and presented the maximal decrement within 12 months. Conclusions Anti-ENO1, anti-H2A and anti-ANXA1 antibodies were associated with high proteinuria in LN patients and Anti-ENO1 also presented the maximal reduction within 12 months that paralleled the decrease of proteinuria. Anti-dsDNA were not associated with renal outcome parameters. New IgG2 antibody signatures should be utilized as tracers of personalized therapies in LN.

Background: Sexual abstinence is considered one of the several factors that influence sperm quality. Recent studies show that a shortening of the abstinence period could be beneficial mostly in oligoasthenoteratozoospermic (OAT) patients. Objective: Retrospective study to verify the efficacy of a second semen sample after a short abstinence to treat severe OAT infertile patients. Materials and methods: 127 couples treated between May 2014 and May 2018 were divided into two groups. Study Group 1 (75 cycles): severe OAT characteristics: count

PurposeThe main purpose and research question of the study are to compare the efficacy of high-security closed versus open devices for human oocytes’ vitrification.MethodsA prospective randomized study was conducted. A total of 737 patients attending the Infertility and IVF Unit at S.Orsola University Hospital (Italy) between October 2015 and April 2020 were randomly assigned to two groups. A total of 368 patients were assigned to group 1 (High-Security Vitrification™ - HSV) and 369 to group 2 (Cryotop® open system). Oocyte survival, fertilization, cleavage, pregnancy, implantation, and miscarriage rate were compared between the two groups.ResultsNo statistically significant differences were observed on survival rate (70.3% vs. 73.3%), fertilization rate (70.8% vs. 74.9%), cleavage rate (90.6% vs. 90.3%), pregnancy/transfer ratio (32.0% vs. 31.8%), implantation rate (19.7% vs. 19.9%), nor miscarriage rates (22.1% vs. 21.5%) between the two groups. Women’s mean age in group 1 (36.18 ± 3.92) and group 2 (35.88 ± 3.88) was not significantly different (P= .297). A total of 4029 oocytes were vitrified (1980 and 2049 in groups 1 and 2 respectively). A total of 2564 were warmed (1469 and 1095 in groups 1 and 2 respectively). A total of 1386 morphologically eligible oocytes were inseminated by intracytoplasmic sperm injection (792 and 594 respectively,P= .304).ConclusionsThe present study shows that the replacement of the open vitrification system by a closed one has no impact on in vitro and in vivo survival, development, pregnancy and implantation rate. Furthermore, to ensure safety, especially during the current COVID-19 pandemic, the use of the closed device eliminates the potential samples’ contamination during vitrification and storage.

Objective To examine the magnitude and the predictors of emotional reactions to an infertility diagnosis, comparing women and men who were clinically diagnosed with an anatomical cause of infertility or non-anatomical cause of infertility. Study design Cross-sectional study involving a total of 133 adults waiting for infertility treatment at the IVF and Infertility Unit of the S. Orsola University Hospital in Bologna (Italy). Of these, 107 patients (55 with anatomical causes of infertility and 52 with non-anatomical causes of infertility; response rate: 80%) took part to the study. After providing informed written consent, each participant was asked to complete the Infertility Self-efficacy Scale, the Fertility Quality of Life, and the Brief Coping Orientation to Problem Experienced, which they returned at their second access to the Unit. Differences between the groups were analyzed through a series of univariate ANOVA, whereas a multiple regression analysis was used to jointly examine the predictors of fertility quality of life. Results Results showed both gender related and diagnosis related differences. Women had statistically significant lower scores than men on the Infertility Self-Efficacy Scale and on the global, emotional, and mind–body subscales of the Fertility Quality of Life, while they scored significantly higher on the emotion focused and socially supported subscales of the Coping Orientation to Problem Experienced. Independently of gender, patients with non-anatomical causes of infertility scored poorly than patients with anatomical causes of infertility on the relational subscale of the Fertility Quality of Life and on the Avoidant scale of the Brief Coping Orientation to Problem Experienced. Hierarchical multiple regression analyses revealed that higher levels of self-efficacy and a lower use of avoidant coping strategies predicted a more positive quality of life over and above gender and cause of infertility. Conclusion This study partly confirms data on gender differences in experiencing the psychological burden of infertility and adds some new information, particularly with respect to the prediction of quality of life indicators over and above infertility cause.

Purpose To determine the impact of BRCA1 and BRCA2 mutations on ovarian reserve and fertility preservation outcome. The main purpose and research question of the study is to determine the impact of BRCA1 and BRCA2 mutations on ovarian reserve and fertility preservation outcomes. Methods Prospective study: 67 breast cancer patients between 18 and 40 years old, undergoing a fertility preservation by means of oocyte storage were considered. Inclusions criteria for the study were age between 18 and 40 years old, BMI between 18 and 28, breast cancer neoplasm stage I and II according to American Joint Committee on Cancer classification (2017) and no metastasis. Exclusion criteria: age over 40 years old, BMI 28, breast cancer neoplasm stage III and IV and do not performed the BRCA test. A total of 21 patients had not performed the test and were excluded. Patients were divided into four groups: Group A was composed by 11 breast cancer patients with BRCA 1 mutations, Group B was composed by 11 breast cancer patients with BRCA 2 mutations, Group C was composed by 24 women with breast cancer without BRCA mutations, and Group D (control) was composed by 181 normal women. Results Group A showed significant lower AMH levels compared to Group C and D (1.2 ± 1.1 vs 4.5 ± 4.1 p p p p p Conclusions The study showed that BRCA1 patients had a higher risk of premature ovarian insufficiency (POI) confirmed by a diminished ovarian reserve and a lower number of mature oocytes suitable for cryopreservation.
