I social network, professionali e non, sono sempre più utilizzati nelle procedure di ricerca e selezione del personale. Il presente articolo, che si basa sulle evidenze empiriche provenienti dalla letteratura scientifica, vuole fornire una prima visione sui limiti e i punti di forza di queste pratiche. Vengono riportati i risultati degli studi circa la validità delle valutazioni basate sui social network e circa le reazioni dei candidati in merito all’impiego di queste procedure. Il quadro che emerge spinge a adottare molta cautela nell’impiego di tali strumenti in ottica di valutazione dei candidati.

Background: Long-standing ulcerative colitis has been associated with an increased risk of colorectal cancer (CRC). Current guidelines recommend endoscopic CRC screening after 8 years of disease duration. The objectives of our study were to assess the adherence to recommendations and the quality of endoscopic procedure in long-standing ulcerative colitis. Methods: This is a retrospective cohort study. We selected patients included in the Swiss IBD cohort with a disease duration of ≥8 years and an extension above the rectosigmoid junction. The complementary medical chart review focused on endoscopy and associated histological reports in 8 Swiss centers. Descriptive analyses focused on patients and their colonoscopies. Results: 309 colonoscopies were conducted among 116 patients with the following characteristics: women 47%, mean age at diagnosis 31 years, and pancolitis disease extent in 65.5% of cases; 38.8% of patients had a first screening colonoscopy 10 years. Cecal intubation was performed in 94.5% of cases, and bowel preparation was good to excellent in 61.5% of endoscopies. Chromoendoscopy was used in 7.4% of cases, and the mean withdrawal time was 16.4 min. Dysplasia was found in 6.2% of cases. Conclusion: Despite current international recommendations, a significant number of patients did not receive a proper endoscopic surveillance. An increased use of chromoendoscopy, monitoring of withdrawal time, and appropriate bowel preparation would increase the quality of CRC screening. The adherence to screening guidelines and endoscopic quality should be promoted and standardized.

Here we presented a single electroencephalographic (EEG) marker for a neurophysiological assessment of Alzheimer’s disease (AD) patients already diagnosed by current guidelines. The ability of the EEG marker to classify 127 AD individuals and 121 matched cognitively intact normal elderly (Nold) individuals was tested. Furthermore, its relationship to AD patients’ cognitive status and structural brain integrity was examined. Low-resolution brain electromagnetic tomography (LORETA) freeware estimated cortical sources of resting state eyes-closed EEG rhythms. The EEG marker was defined as the ratio between the activity of parieto-occipital cortical sources of delta (2–4 Hz) and low-frequency alpha (8–10.5 Hz) rhythms. Results showed 77.2% of sensitivity in the recognition of the AD individuals; 65% of specificity in the recognition of the Nold individuals; and 0.75 of area under the receiver-operating characteristic curve. Compared to the AD subgroup with the EEG maker within one standard deviation of the Nold mean (EEG-), the AD subgroup with EEG+ showed lower global cognitive status, as revealed by Mini-Mental State Evaluation score, and more abnormal values of white-matter and cerebrospinal fluid normalized volumes, as revealed by structural magnetic resonance imaging. We posit that cognitive and functional status being equal, AD patients with EEG+ should receive special clinical attention due to a neurophysiological “frailty”. EEG+ label can be also used in clinical trials (i) to form homogeneous groups of AD patients diagnosed by current guidelines and (ii) as end-point to evaluate intervention effects.

Background A possible and neglected concern in women with endometriosis undergoing IVF is the potential risk of progression of the disease. We set up a prospective study mainly aimed at evaluating the impact of IVF on endometriosis-related symptoms. Materials and methods Women with surgical or echographic diagnosis of endometriosis and selected for IVF were included. In the month preceding the IVF attempt and at a second evaluation 3-6 months after the cycle, women who did not get pregnant underwent clinical assessment and transvaginal ultrasonography. Each patient was requested to complete a questionnaire on the presence, severity and modifications of endometriosis-related symptoms before and after the IVF cycle. Results Overall, 64 patients completed the study protocol. The Biberoglu-Behrman Scores and the Verbal Rate Scales for dysmenorrhea, dispareunia and chronic pelvic pain did not worsen after the procedure. Other endometriosis-related symptoms also did not change. There was no modification in size and number of endometriomas and deep peritoneal nodules. The number (%) of women reporting general improvement and worsening were 14 (22%) and 7 (11%), respectively. Conclusions IVF does not expose women to a consistent risk of endometriosis-related symptoms progression.

Objective In infertile women with endometriosis requiring an in vitro fertilization (IVF) procedure, the potential risk of an IVF-related progression of the disease remains a matter of debate. Thus, since available data on this issue are scanty and controversial, an observational study has been herein conducted in order to clarify this issue. Study design We recruited 233 women with endometriosis who underwent IVF cycles in our unit. Patients were contacted to assess whether they experienced recurrences of the disease after IVF. The main outcome was to evaluate the impact of the number of IVF cycles and the responsiveness to ovarian hyperstimulation on the likelihood of recurrence. Clinical characteristics of women who did and did not have a recurrence were compared. Results One hundred and eighty-nine women were included, 41 of whom (22%) had a diagnosis of endometriosis recurrence. The 36 months cumulative recurrence rate was 20%. The number of IVF cycles and the responsiveness to ovarian hyperstimulation were not associated with the risk of disease recurrence. The adjusted OR for recurrences according to the number of started cycles was 0.92 (95% CI: 0.77–1.10) per cycle (p = 0.35). The adjusted OR for recurrences in women with intact versus compromised ovarian reserve was 0.80 (95% CI: 0.40–1.58) (p = 0.52). Conclusions IVF procedures do not seem to influence the likelihood of endometriosis recurrence.

There is increasing evidence of white matter (WM) pathology in schizophrenia, but its role at the very early stage of the disorder remains unclear. In an exploration of WM microstructure in ultra-high risk (UHR) subjects and first episode schizophrenia (FES), 34 FES, 27 UHR and 26 healthy control (HC) subjects underwent a magnetic resonance imaging (MRI) tract based spatial statistics (TBSS) investigation. Whole brain fractional anisotropy (FA), mean diffusivity (MD), radial (RD) and axial diffusivity (AD) values were extracted. UHR subjects who later developed psychosis showed lower FA compared with HC in the corpus callosum (CC), the left superior and inferior longitudinal fasciculus, the left inferior fronto-occipital fasciculs (IFO), and the forceps; RD was significantly higher in the CC, the forceps, the anterior thalamic radiation bilaterally, and the cingulum bundle. FES, compared to HC, showed a significant FA reduction of the CC, the superior and inferior longitudinal fasciculi bilaterally, the IFO bilaterally, the corona radiate bilaterally, and the forceps; while RD was found to be significantly increased in the left superior longitudinal fasciculus. UHR who later developed psychosis had WM abnormalities affecting brain pathways that are crucial for intra- and inter-hemispheric connections.

Background/Aims: Limited information is available regarding the quantity of blood loss associated with uncomplicated transvaginal oocyte retrieval. The aim of the present study was evaluating the quantity of such a loss. Methods: One hundred and fifty consecutive women undergoing oocyte retrieval were recruited. They underwent blood test assessment and ultrasonographic transvaginal evaluation at three different times: (1) immediately before initiating oocyte retrieval, (2) 4–6 h later, and (3) 72 h later. Results: At 4–6 h after oocyte retrieval, the red blood cell count and the hemoglobin concentration were significantly reduced, whereas pelvic free fluid had significantly increased. The estimated median (Interquartile range) blood loss was 72 (–8/162) ml. None of the recruited women was found to have a hemoglobin reduction >2 g/day or an increase in the pelvic free fluid >200 ml or a calculated blood loss >500 ml (0.0%, 95% CI: 0.0–2.4%). No significant worsening from baseline was observed at the 72 h evaluation. Conclusions: The quantity of blood loss following oocyte retrieval is clinically unremarkable in the vast majority of women.
