OBJECTIVE: To describe the oncological and obstetrical outcomes of women diagnosed with borderline ovarian tumors or epithelial ovarian cancer during pregnancy. METHODS: This is an international retrospective cohort study. Patients were eligible for inclusion if they were diagnosed with borderline tumor or invasive ovarian cancer during pregnancy, with histologic confirmation either before or after delivery, and were registered in the International Network on Cancer, Infertility and Pregnancy database between 1982 and 2019. RESULTS: A total of 129 patients were included, of whom 69 (53%) with borderline and 60 (47%) with invasive cancer. Diagnosis was established in the first, second, and third trimesters in 59 (46%), 48 (37%), and 22 (17%) patients, respectively. In total, 47 (36%) patients did not receive any treatment during pregnancy. The majority of patients (64%) underwent surgery with or without chemotherapy during pregnancy. Birthweight was significantly lower in women who received chemotherapy during pregnancy as compared to those who did not (median birthweight 2528 g vs 3031 g, p = .01) Among patients with borderline tumors, 20 (29%) experienced a relapse of whom 2 subsequently died from the disease. The 5-year survival probability was 98.5% (95% CI 95.6 to 100). Recurrence was associated with incomplete surgical staging (p = .02). Among patients with epithelial ovarian cancer, the relapse rate was 25% and the 5-year survival probability was 83.6% (95% CI 74.3 to 94.1). The oncological outcome was worse for patients with advanced-stage disease (p = .03). In addition, 66% of patients who relapsed after pregnancy did not undergo adequate surgical staging. CONCLUSIONS: Treatment of patients with ovarian cancer during pregnancy can result in favorable oncological and obstetrical outcomes. Better oncological outcomes are achieved when treatment adheres to the standard of care in non-pregnant patients, as those who did not undergo surgical staging experienced a higher relapse rate.

A double primary colorectal cancer (CRC) in a familial setting signals a high risk of CRC. In order to identify novel CRC susceptibility genes, we whole-exome sequenced germline DNA from nine persons with a double primary CRC and a family history of CRC. The detected variants were processed by bioinformatics filtering and prioritization, including STRING protein-protein interaction and pathway analysis. A total of 150 missense, 19 stop-gain, 22 frameshift and 13 canonical splice site variants fulfilled our filtering criteria. The STRING analysis identified 20 DNA repair/cell cycle proteins as the main cluster, related to genes CHEK2, EXO1, FAAP24, FANCI, MCPH1, POLL, PRC1, RECQL, RECQL5, RRM2, SHCBP1, SMC2, XRCC1, in addition to CDK18, ENDOV, ZW10 and the known mismatch repair genes. Another STRING network included extracellular matrix genes and TGFβ signaling genes. In the nine whole-exome sequenced patients, eight harbored at least two candidate DNA repair/cell cycle/TGFβ signaling gene variants. The number of families is too small to provide evidence for individual variants but, considering the known role of DNA repair/cell cycle genes in CRC, the clustering of multiple deleterious variants in the present families suggests that these, perhaps jointly, contributed to CRC development in these families.

BACKGROUND: Advances in paediatric type 1 diabetes management and increased use of diabetes technology have led to improvements in glycaemia, reduced risk of severe hypoglycaemia, and improved quality of life. Since 1993, progressively lower HbA1c targets have been set. The aim of this study was to perform a longitudinal analysis of HbA1c, treatment regimens, and acute complications between 2013 and 2022 using data from eight national and one international paediatric diabetes registries. METHODS: In this longitudinal analysis, we obtained data from the Australasian Diabetes Data Network, Czech National Childhood Diabetes Register, Danish Registry of Childhood and Adolescent Diabetes, Diabetes Prospective Follow-up Registry, Norwegian Childhood Diabetes Registry, England and Wales' National Paediatric Diabetes Audit, Swedish Childhood Diabetes Registry, T1D Exchange Quality Improvement Collaborative, and the SWEET initiative. All children (aged ≤18 years) with type 1 diabetes with a duration of longer than 3 months were included. Investigators compared data from 2013 to 2022; analyses performed on data were pre-defined and conducted separately by each respective registry. Data on demographics, HbA1c, treatment regimen, and event rates of diabetic ketoacidosis and severe hypoglycaemia were collected. ANOVA was performed to compare means between registries and years. Joinpoint regression analysis was used to study significant breakpoints in temporal trends. FINDINGS: In 2022, data were available for 109 494 children from the national registries and 35 590 from SWEET. Between 2013 and 2022, the aggregated mean HbA1c decreased from 8·2% (95% CI 8·1-8·3%; 66·5 mmol/mol [65·2-67·7]) to 7·6% (7·5-7·7; 59·4mmol/mol [58·2-60·5]), and the proportion of participants who had achieved HbA1c targets of less than 7% (<53 mmol/mol) increased from 19·0% to 38·8% (p<0·0001). In 2013, the aggregate event rate of severe hypoglycaemia rate was 3·0 events per 100 person-years (95% CI 2·0-4·9) compared with 1·7 events per 100 person-years (1·0-2·7) in 2022. In 2013, the aggregate event rate of diabetic ketoacidosis was 3·1 events per 100 person-years (95% CI 2·0-4·8) compared with 2·2 events per 100 person-years (1·4-3·4) in 2022. The proportion of participants with insulin pump use increased from 42·9% (95% CI 40·4-45·5) in 2013 to 60·2% (95% CI 57·9-62·6) in 2022 (mean difference 17·3% [13·8-20·7]; p<0·0001), and the proportion of participants using continuous glucose monitoring (CGM) increased from 18·7% (95% CI 9·5-28·0) in 2016 to 81·7% (73·0-90·4) in 2022 (mean difference 63·0% [50·3-75·7]; p<0·0001). INTERPRETATION: Between 2013 and 2022, glycaemic outcomes have improved, parallel to increased use of diabetes technology. Many children had HbA1c higher than the International Society for Pediatric and Adolescent Diabetes (ISPAD) 2022 target. Reassuringly, despite targeting lower HbA1c, severe hypoglycaemia event rates are decreasing. Even for children with type 1 diabetes who have access to specialised diabetes care and diabetes technology, further advances in diabetes management are required to assist with achieving ISPAD glycaemic targets.

BACKGROUND: Endoscopic retrograde cholangiopancreatography (ERCP) still has a relatively high complication rate, underscoring the importance of high-quality training. Despite existing guidelines, real-world data on training conditions remain limited. This pan-European survey aims to systematically explore the perceptions surrounding ERCP training. METHODS: A survey was distributed through the friends of United European Gastroenterology (UEG) Young Talent Group network to physicians working in a UEG member or associated states who regularly performed ERCPs. RESULTS: Of 1035 respondents from 35 countries, 649 were eligible for analysis: 228 trainees, 225 trainers, and 196 individuals who regularly performed ERCP but were neither trainees nor trainers. The mean age was 43 years, with 72.1% identifying as male, 27.6% as female, and 0.3% as non-binary. The majority (80.1%) agreed that a structured training regimen is desirable. However, only 13.7% of trainees and 28.4% of trainers reported having such a structured program in their institutions. Most respondents (79.7%) supported the concept of concentrating training in centers meeting specific quality metrics, with 64.1% suggesting a threshold of 200 annual ERCPs as a prerequisite. This threshold revealed that 36.4% of trainees pursued training in lower-volume centers performing <200 ERCPs annually. As many as 70.1% of trainees performed <50 annual ERCPs, whereas only 5.0% of trainers performed <50 ERCPs annually. A low individual trainee caseload (<50 ERCPs annually) was more common in lower-volume centers than in higher-volume centers (82.9% vs. 63.4%). CONCLUSIONS: The first pan-European survey investigating ERCP training conditions reveals strong support for structured training and the concentration of training efforts within centers meeting specific quality metrics. Furthermore, this survey exposes the low availability of structured training programs with many trainees practicing at lower-volume centers and 71% of all trainees having little hands-on exposure. These data should motivate to standardize ERCP training conditions further and ultimately improve patient care throughout Europe.

BACKGROUND: Modafinil is primarily used to treat narcolepsy but is also used as an off-label cognitive enhancer. Functional magnetic resonance imaging studies indicate that modafinil modulates the connectivity of neocortical networks primarily involved in attention and executive functions. However, much less is known about the drug's effects on subcortical structures. Following preliminary findings, we evaluated modafinil's activity on the connectivity of distinct cerebellar regions with the neocortex. We assessed the spatial relationship of these effects with the expression of neurotransmitter receptors/transporters. METHODS: Patterns of resting-state functional magnetic resonance imaging connectivity were estimated in 50 participants from scans acquired pre- and postadministration of a single (100 mg) dose of modafinil (n = 25) or placebo (n = 25). Using specific cerebellar regions as seeds for voxelwise analyses, we examined modafinil's modulation of cerebellar-neocortical connectivity. Next, we conducted a quantitative evaluation of the spatial overlap between the modulation of cerebellar-neocortical connectivity and the expression of neurotransmitter receptors/transporters obtained by publicly available databases. RESULTS: Modafinil increased the connectivity of crus I and vermis IX with prefrontal regions. Crus I connectivity changes were associated with the expression of dopaminergic D2 receptors. The vermis I-II showed enhanced coupling with the dorsal anterior cingulate cortex and matched the expression of histaminergic H3 receptors. The vermis VII-VIII displayed increased connectivity with the visual cortex, an activity associated with dopaminergic and histaminergic neurotransmission. CONCLUSIONS: Our study reveals modafinil's modulatory effects on cerebellar-neocortical connectivity. The modulation mainly involves crus I and the vermis and spatially overlaps the distribution of dopaminergic and histaminergic receptors.

BACKGROUND: Cell cycle progression and leukemia development are tightly regulated processes in which even a small imbalance in the expression of cell cycle regulatory molecules and microRNAs (miRNAs) can lead to an increased risk of cancer/leukemia development. Here, we focus on the study of a ubiquitous, multifunctional, and oncogenic miRNA-hsa-miR-155-5p (miR-155, MIR155HG), which is overexpressed in malignancies including chronic lymphocytic leukemia (CLL). Nonetheless, the precise mechanism of how miR-155 regulates the cell cycle in leukemic cells remains the subject of extensive research. METHODS: We edited the CLL cell line MEC-1 by CRISPR/Cas9 to introduce a short deletion within the MIR155HG gene. To describe changes at the transcriptome and miRNome level in miR-155-deficient cells, we performed mRNA-seq/miRNA-seq and validated changes by qRT-PCR. Flow cytometry was used to measure cell cycle kinetics. A WST-1 assay, hemocytometer, and Annexin V/PI staining assessed cell viability and proliferation. RESULTS: The limited but phenotypically robust miR-155 modification impaired cell proliferation, cell cycle, and cell ploidy. This was accompanied by overexpression of the negative cell cycle regulator p21/CDKN1A and Cyclin D1 (CCND1). We confirmed the overexpression of canonical miR-155 targets such as PU.1, FOS, SHIP-1, TP53INP1 and revealed new potential targets (FCRL5, ISG15, and MX1). CONCLUSIONS: We demonstrate that miR-155 deficiency impairs cell proliferation, cell cycle, transcriptome, and miRNome via deregulation of the MIR155HG/TP53INP1/CDKN1A/CCND1 axis. Our CLL model is valuable for further studies to manipulate miRNA levels to revert highly aggressive leukemic cells to nearly benign or non-leukemic types.

Tailocins are nano-scale phage tail-like protein complexes that can mediate antagonistic interactions between closely related bacterial species. While the capacity to produce R-type tailocin was found widely across Gammaproteobacteria, the production of F-type tailocins seems comparatively rare. In this study, we examined the freshwater isolate, Pragia fontium 24613, which can produce both R- and F-type tailocins. We investigated their inhibition spectrum, focusing on clinically relevant enterobacteria, and identified the associated tailocin gene cluster. Transmission electron microscopy confirmed that inactivation of the tape measure protein within the tailocin cluster disrupted R-tailocin production. Comparative analysis of Budviciaceae gene clusters showed high conservation of R-type tailocin genes, whereas F-type tailocin genes were found in only a few species, with little conservation. Our findings indicate a high prevalence of bacteriocin production among underexplored Enterobacteriales species. Detected tailocins showed potential as antimicrobials targeting clinically significant pathogens.
Poly(ɛ-caprolactone) (PCL) is a biocompatible, biodegradable, and highly mechanically resilient FDA-approved material (for specific biomedical applications, e.g. as drug delivery devices, in sutures, or as an adhesion barrier), rendering it a promising candidate to serve bone tissue engineering. However, in vivo monitoring of PCL-based implants, as well as biodegradable implants in general, and their degradation profiles pose a significant challenge, hindering further development in the tissue engineering field and subsequent clinical adoption. To address this, photo-cross-linkable mechanically resilient PCL networks are developed and functionalized with a radiopaque monomer, 5-acrylamido-2,4,6-triiodoisophthalic acid (AATIPA), to enable non-destructive in vivo monitoring of PCL-based implants. The covalent incorporation of AATIPA into the crosslinked PCL networks does not significantly affect their crosslinking kinetics, mechanical properties, or thermal properties, but it increases their hydrolysis rate and radiopacity. Complex and porous 3D designs of radiopaque PCL networks can be effectively monitored in vivo. This work paves the way toward non-invasive monitoring of in vivo degradation profiles and early detection of potential implant malfunctions.

OBJECTIVE: Research suggests that disrupted interoception contributes to the development and maintenance of functional neurological disorder (FND); however, no functional neuroimaging studies have examined the processing of interoceptive signals in patients with FND. METHODS: The authors examined univariate and multivariate functional MRI neural responses of 38 patients with mixed FND and 38 healthy control individuals (HCs) during a task exploring goal-directed attention to cardiac interoception-versus-control (exteroception or rest) conditions. The relationships between interoception-related neural responses, heartbeat-counting accuracy, and interoceptive trait prediction error (ITPE) were also investigated for FND patients. RESULTS: When attention was directed to heartbeat signals versus exteroception or rest tasks, FND patients showed decreased neural activations (and reduced coactivations) in the right anterior insula and bilateral dorsal anterior cingulate cortices (among other areas), compared with HCs. For FND patients, heartbeat-counting accuracy was positively correlated with right anterior insula and ventromedial prefrontal activations during interoception versus rest. Cardiac interoceptive accuracy was also correlated with bilateral dorsal anterior cingulate activations in the interoception-versus-exteroception contrast, and neural activations were correlated with ITPE scores, showing inverse relationships to those observed for heartbeat-counting accuracy. CONCLUSIONS: This study identified state and trait interoceptive disruptions in FND patients. Convergent between- and within-group findings contextualize the pathophysiological role of cingulo-insular (salience network) areas across the spectrum of functional seizures and functional movement disorder. These findings provide a starting point for the future development of comprehensive neurophysiological assessments of interoception for FND patients, features that also warrant research as potential prognostic and monitoring biomarkers.

Necrotizing enterocolitis (NEC) is a severe intestinal condition primarily affecting preterm neonates. It has a high mortality rate, particularly in infants with a birthweight of below 1,500 g or for those requiring surgical intervention. The European Reference Network for Inherited and Congenital Anomalies (ERNICA) has developed a clinical practice guideline to aid clinical decision-making pertaining to the surgical treatment and management of NEC in preterm neonates. This guideline was developed in accordance with the Guidelines 2.0 checklist and GRADE methodology. A multidisciplinary group of Europe's top experts collaborated with patient representatives to develop this guideline. After selecting critical points in care for which recommendations are required, a systematic review of the literature and critical appraisal of the evidence was performed. The Evidence to Decision framework was used as a guide to structure the consensus meetings and draft the recommendations. The panel developed seven recommendations and three good practice statements on the following topics: indications for surgery, peritoneal drainage, surgical technique, management of extensive NEC, enteral feeding, and neurodevelopmental outcomes in premature neonates with NEC. The certainty of evidence was graded as (very) low for most recommendations. However, the panel weighed up the benefits and harms in light of all relevant arguments and expert opinion. This guideline provides recommendations on caring for premature neonates with NEC. These recommendations can assist clinicians in their care decisions and can inform families on treatment options and relevant considerations. This guideline will be revised every 5 years to ensure it remains up to date.
