Pigment epithelium-derived factor expression and role in follicular development.

Research Question: What is the involvement of pigment epithelium-derived factor (PEDF), expressed in granulosa cells, in folliculogenesis?

Design: mRNA expression of PEDF and other key factors [Cyp19, anti-Müllerian hormone receptor (AMHR) and vascular endothelial growth factor (VEGF)] in mice follicles was examined in order to typify the expression of PEDF in growing follicles and in human primary granulosa cells (hpGC), and to follow the interplay between PEDF and the other main players in folliculogenesis: FSH and AMH.

Results: mRNA expression of PEDF increased through folliculogenesis, although the pattern differed from that of the other examined genes, affecting the follicular angiogenic and oxidative balance. In hpGC, prolonged exposure to FSH stimulated the up-regulation of PEDF mRNA.

Cesarean Uterine Lacerations and Prematurity in the Following Delivery: A Retrospective Longitudinal Follow-Up Cohort Study.

(1) : We aimed to investigate whether second-stage cesarean delivery (SSCD) had a higher occurrence of low-segment uterine incision extensions compared with cesarean delivery (CD) at other stages of labor and to study the association of these extensions with preterm birth (PTB). (2) : In this retrospective longitudinal follow-up cohort study, spanning from 2006 to 2019, all selected mothers who delivered by CD at first birth (P1) and returned for second birth (P2) were grouped by cesarean stage at P1: planned CD, first-stage CD, or SSCD. Mothers with a PTB at P1, multiple-gestation pregnancies in either P1 or P2 and those with prior abortions were excluded.

Future diabetes risk can be predicted by the number of abnormal oral glucose tolerance test values during pregnancy.

Aim: To quantify the future risk of type 2 diabetes (T2D) in women with gestational diabetes (GD) based on baseline metabolic characteristics and the number of abnormal values during a 3-hour 100-g oral glucose tolerance test (OGTT).

Materials And Methods: We conducted a population-based retrospective cohort study of 10 023 pregnant women who underwent testing for GD in a large health maintenance organization in Israel using a 100-g OGTT. Glucose values were obtained at four time points, 0, 60, 120 and 180 minutes.

Background: Qualitative data on the opinions of anaesthesiologists regarding the impact of peri-operative night-time working conditions on patient safety are lacking.

Objectives: This study aimed to achieve in-depth understanding of anaesthesiologists' perceptions regarding the impact of night-time working conditions on peri-operative patient safety and actions that may be undertaken to mitigate perceived risks.

Design: Qualitative analysis of responses to two open-ended questions.

Global anaesthesia-related cardiac arrest rates in children: a systematic review and meta-analysis.

Background: Neonates and infants have a higher perioperative risk of cardiac arrest and mortality than adults. The Human Development Index (HDI) ranges from 0 to 1, representing the lowest and highest levels of development, respectively. The relation between anaesthesia safety and country HDI has been described previously.

Comparing a novel wide field of view laparoscope with conventional laparoscope while performing laparoscopic cholecystectomy.

Background: The limited 70° field of view (FoV) used in standard laparoscopy necessitates maneuvering the laparoscope to view the ports, follow the surgical tools, and search for a target region. Complications related to events that take place outside the FoV are underreported. Recently, a novel laparoscopic system (SurroundScope, 270Surgical) was reported to dramatically expand the FoV from 70 to 270°.

Nighttime working as perceived by Italian anesthesiologists: a secondary analysis of an international survey.

Background: No data are available on the working conditions and workload of anesthesiologists during perioperative nighttime work in Italy and on the perceived risks.

Results: We analyzed 1085 responses out of the 5292 from the whole dataset. Most of the responders (76%) declared working a median of 12 consecutive hours during night shifts, with an irregular nightshift schedule (70%).

Rapid home therapy infusion of velaglucerase alfa in naïve patients with Gaucher disease.

Background: Enzyme replacement therapy (ERT) has revolutionised the management of patients with Gaucher disease (GD). In 2018, we published the safety and efficacy of rapid 10-min infusion of velaglucerase alfa in previously treated patients, mostly on low-dose therapy.

Aim: To improve quality of life (QoL) for patients needing lifelong bi-weekly infusions by introducing a 10-min infusion instead of 1 h per label in patients naive to ERT and on high-dose therapy.

The yield of procalcitonin and Interleukin-6 in predicting intraamniotic infection in the presence of intrapartum fever: A pilot study.

Intrapartum fever (IF) accompanied by either maternal or foetal tachycardia, elevated WBC, or purulent discharge is classified as "suspected triple 1", the hallmark of intraamniotic infection (IAI). Poor specificity of the clinical diagnosis of IAI results, in retrospect, in the unnecessary treatment of most parturients and neonates. We studied the yield of specific acute phase reactants (APRs): procalcitonin, CRP, IL-6, in detecting bacterial IAI among parturients classified as "suspected triple 1" (cases) compared to afebrile parturients (controls).

How reliable is restaging MRI after neoadjuvant therapy in rectal cancer?

Background: Despite the pivotal role of magnetic resonance imaging (MRI) in rectal cancer staging and evaluation, the reliability of restaging MRI after neoadjuvant therapy is still debatable. This study aimed to assess the accuracy of restaging MRI by comparing post-neoadjuvant MRI findings with those of the final pathology.

Methods: This study was a retrospective review of the medical records of adult rectal cancer patients who had restaging MRI following neoadjuvant therapy and prior to rectal cancer resection in a NAPRC-certified rectal cancer centre between 2016 and 2021.

Effects of wide-angle laparoscopy on surgical workflow in laparoscopic cholecystectomies.

Introduction: Laparoscopy is now the gold standard approach to many surgical procedures thanks to its many advantages. Minimizing distractions is essential to a safe and successful surgery and an undisrupted surgical workflow. The SurroundScope, a wide angle (270°) laparoscopic camera system has the potential to decrease surgical distractions and increase workflow.

Validation of predictive models for disease outcomes in paediatric ulcerative colitis: A multicentre prospective inception cohort.

Background: Several studies have proposed models to predict disease outcomes in paediatric ulcerative colitis (UC), notably PROTECT, Schechter and PIBD-ahead, but none has been validated by external cohorts AIM: To explore these models in a prospective multicentre inception cohort METHODS: Children newly diagnosed with UC in 17 centres were followed at disease onset and 3 and 12 months thereafter, as well as at last visit. Outcomes included steroid-free remission (SFR) and acute severe colitis (ASC).

Results: Of the 223 included children, 74 (34%), 97 (43%) and 52 (23%) presented with mild, moderate and severe disease, respectively.

Care after premenopausal risk-reducing salpingo-oophorectomy in high-risk women: Scoping review and international consensus recommendations.

Women at high inherited risk of ovarian cancer are offered risk-reducing salpingo-oophorectomy (RRSO) from age 35 to 45 years. Although potentially life-saving, RRSO may induce symptoms that negatively affect quality of life and impair long-term health. Clinical care following RRSO is often suboptimal.

Can preoperative CT/MR enterography preclude the development of Crohn's disease-like pouch complications in ulcerative colitis patients undergoing J pouch surgery?

Aim: We aimed to determine whether ulcerative colitis patients with preoperative negative computed tomography or magnetic resonance enterography (CTE/MRE) were less likely to develop Crohn's disease-like pouch complications (CDLPC) and establish risk factors and predictors for developing CDLPC.

Methods: This was a single centre retrospective analysis of patients with ulcerative colitis (UC) and inflammatory bowel disease unclassified (IBDU) who underwent total proctocolectomy with ileal J-pouch between January 2010 and December 2020. The study group comprised patients with negative preoperative CTE/MRE and the control group included patients operated without preoperative CTE/MRE.

Clinical Phenotype in Individuals With Birk-Landau-Perez Syndrome Associated With Biallelic Pathogenic Variants.

Background And Objectives: Birk-Landau-Perez syndrome is a genetic disorder caused by biallelic pathogenic variants in presenting with a complex movement disorder, developmental regression, oculomotor abnormalities, and renal impairment. It has previously been reported in 2 families. We describe the clinical phenotype of 8 further individuals from 4 unrelated families with -related disease.

The Bone Biomarker of Quantitative Chemical Shift Imaging in Patients with Type 1 Gaucher Disease Receiving Low-Dose Long-Term Enzyme Replacement Therapy.

Quantitative chemical shift imaging (QCSI) is the most sensitive imaging biomarker to assess bone marrow involvement in Gaucher disease. Widespread QCSI use is limited by test availability. Anecdotal reports describe two patients demonstrating significant improvement in fat fraction (FF) assessed by QCSI following a switch from imiglucerase to taliglucerase alfa.

Infantile-onset inflammatory bowel disease has variable long-term outcomes.

Objective And Aim: Infantile-onset inflammatory bowel disease (IO-IBD), defined as IBD diagnosed at age 2 years or younger, tends to be more severe and refractory to conventional treatment than IBD diagnosed at a later age. However, data about IO-IBD and its long-term follow up are limited. We thus aimed to evaluate the presentation and long-term outcomes of patients with IO-IBD in a retrospective multicenter study.

Resource allocation.
