Exosomes released from tumour cells are packed with unique RNA and protein cargo, and they are emerging as an important mediator in the communication network that promotes tumour progression. The facultative intracellular bacterium

(Fn) is an important colorectal cancer (CRC)-associated bacterium. To date, the function of exosomes from Fn-infected CRC cells has not been explored.

Exosomes were isolated by sequential differential centrifugation and verified by transmission electron microscopy, NanoSight analysis and Western blotting. Given that exosomes have been shown to transport miRNAs and proteins to alter cellular functions, we performed miRNA sequencing and proteome analysis of exosomes from Fn-infected and non-infected cells. The biological role and mechanism of exosomes from Fn-infected cells in CRC tumour growth and liver metastasis were determined in vitro and in vivo.

We demonstrated that exosomes delivered miR-1246/92b-3p/27a-3p and CXCL16/RhoA/IL-8 from Fn-infected cells into non-infected cells to increase cell migration ability in vitro and promote tumour metastasis in vivo. Finally, both circulating exosomal miR-1246/92b-3p/27a-3p and CXCL16 levels were closely associated with Fn abundance and tumour stage in patients with CRC.

This study suggests that Fn infection may stimulate tumour cells to generate miR-1246/92b-3p/27a-3p-rich and CXCL16/RhoA/IL-8 exosomes that are delivered to uninfected cells to promote prometastatic behaviours.

The management of pregnant women with an adnexal tumor is still challenging and in the literature few data are available. The aim of this study was to describe the management and outcome of patients with ovarian masses detected during pregnancy. As secondary aims, we evaluated the prevalence of malignancy in the International Ovarian Tumor Analysis (IOTA) morphological classes of ovarian masses diagnosed during pregnancy, and created an algorithm for the management of patients with adnexal masses during pregnancy.

This was a retrospective single centered study including patients with adnexal masses detected at any trimester during pregnancy between January 2000 and December 2019. Clinical, ultrasound, surgical, and histological data were retrieved from medical records as well as information on management (ultrasound follow-up vs surgery). CC90011 Indications for surgery were recorded in terms of suspicion of malignancy based on pattern recognition of the ultrasound examiner or on symptoms or prevention of complicr patients in the surveillance group or in those with benign, borderline, or primary epithelial invasive histology. In contrast, two neonatal deaths were observed in patients with ovarian choriocarcinoma and ovarian metastases. Three of the four patients with ovarian metastases died after pregnancy.

IOTA ultrasound morphological classification seems useful in the characterization of ovarian masses during pregnancy. A clinical and morphological based algorithm for counseling patients has been designed.

Hysterectomy is traditionally part of the surgical treatment for advanced high-grade epithelial ovarian carcinomas, although the incidence of uterine involvement has not been fully investigated. Some young patients with advanced high-grade epithelial ovarian carcinomas want uterine preservation. We aimed to determine the frequency of non-serosal (deep) uterine involvement in patients with high-grade epithelial ovarian carcinomas and to establish predictive factors for such involvement.

A retrospective cohort study was performed of 366 consecutive patients with advanced high-grade epithelial ovarian carcinomas who had surgery between January 2012 and December 2019. Data collected included demographic and clinical details, and surgical and pathological reports to determine macroscopic and microscopic deep uterine involvement. The characteristics of the patients with and without deep uterine involvement were compared and univariate and multivariate Cox proportional hazard models were used to assess correlati5 >1000 U. Patients who desire uterine preservation should be advised on an individual basis, given these factors and the operative findings.

Abusive head trauma (AHT) warrants particular attention in terms of prevention. One of the key questions asked is how often AHT occurs in infant day care centers compared with private parental or nonparental homes. To investigate this, we studied the caretaking arrangement and child's location at the time of injury in a cohort of cases involving AHT from the courts.

This multicenter retrospective study covering an 18-year period included all medical and court records of 323 children (2.5 months to 3 years) with AHT, confirmed by the authors acting as medical experts. All markers for abuse and forensic written reports were analyzed by using a standardized data collection tool. The usual child care arrangement and the child's location at the time of injury were noted. The percentage of day care centers found in the study was compared to the expected rate in the French population (19.5%) by using the χ

test.

In 317 AHT cases (98.5%), the assault occurred in a private home (4 in other indoor settings and 1 with missing data). In only 1 case, shaking occurred in a day care center when the nurse was alone with the infant for a few minutes. In 317 cases (98.5%), the usual child care arrangement was by a single adult in charge of 1 or more children.

The fact that AHT is an unusual occurrence in day care centers could help social service agencies make decisions in terms of prevention. Recent government policies regarding stay-at-home orders during a pandemic have given this issue new relevance.
