OBJECTIVE: Transmural healing (TH) is emerging as a potential Crohn´s Disease (CD) treatment target. Early biological treatment seems to be associated with improved disease outcomes, but its impact on TH remains unclear. We aimed to assess the impact of early biological treatment initiation on TH and its influence on CD prognosis.
METHODS: This multicenter retrospective study included adult CD patients starting biological therapy. TH was assessed using magnetic resonance enterography (MRE) at 12±6 months post-therapy initiation, with radiological examinations reviewed by blinded expert radiologists. TH was defined as complete normalization of all MRE parameters. Timing of biological therapy initiation was analyzed as a continuous variable, with optimal cut-off determined using the Youden index and clinical relevance. Logistic regression with propensity score-adjusted analysis was used to assess the association between early biological therapy initiation and TH. Long-term outcomes (bowel damage progression, CD-related surgery, CD-flare hospitalization, and therapy escalation) were evaluated.
RESULTS: Among 154 CD patients, early biological therapy initiation within 12 months of diagnosis was associated with significantly higher TH rates (aOR 3.23, 95% CI 1.36-7.70, p<0.01), which persisted after adjusting for previous biological therapy use (aOR 2.82, 95% CI 1.13-7.06, p=0.03). Time-to-event analysis demonstrated that TH was significantly associated with reduced time until bowel damage progression (aHR 0.28, 95% CI 0.10-0.79, p=0.02), CD-related surgery (aHR 0.21, 95% CI 0.05-0.88, p=0.03) and therapy escalation (aHR 0.35, 95%CI 0.14-0.88, p=0.02), independently of early biological therapy.
CONCLUSIONS: Early initiation of biological therapy within 12 months of diagnosis significantly increases TH rates, leading to improved long-term outcomes in CD patients.

Premature ejaculation (PE) is a common male sexual dysfunction that can cause significant distress in the patient and partner. This study aimed to compare the current international guidelines on PE to highlight their similarities and differences. We examined the latest guidelines from the European Association of Urology (EAU), American Urological Association/Sexual Medicine Society of North America (AUA/SMSNA), and International Society of Sexual Medicine (ISSM) by comparing definitions, classifications, epidemiology, pathophysiology, and recommendations on diagnosis and therapy. The quality of guidelines was assessed using the Appraisal of Guidelines for Research and Evaluation (AGREE) Global Rating Scale (GRS). We found significant variations in the definitions of PE and recommendations on management of patients. The EAU guidelines were the most recent, the AUA/SMSNA guidelines lacked detail in some areas, and the ISSM guidelines were the most complete but also the least updated. The search for a unified definition and the development of standardized diagnostic and therapeutic pathways remain concrete issues to improve the management of patients with PE worldwide.

BACKGROUND: Alzheimer\'s disease (AD) is the most prevalent dementia, showing higher incidence in women. Besides, lipids play an essential role in brain, and they could be dysregulated in neurodegeneration. Specifically, impaired plasma lipid levels could predict early AD diagnosis. This work aims to identify the main plasma lipids altered in early AD female mouse model and evaluate their relationship with brain lipidome. Also, the possible involvement of the estrous cycle in lipid metabolism has been evaluated.
METHODS: Plasma samples of wild-type (n = 10) and APP/PS1 (n = 10) female mice of 5 months of age were collected, processed, and analysed using a lipidomic mass spectrometry-based method. A statistical analysis involving univariate and multivariate approaches was performed to identify significant lipid differences related to AD between groups. Also, cytology tests were conducted to confirm estrous cycle phases.
RESULTS: Three hundred thirty lipids were detected in plasma, 18 of them showed significant differences between groups; specifically, some triacylglycerols, cholesteryl esters, lysophosphatidylcholines, phosphatidylcholines, and ether-linked phosphatidylcholines, increased in early AD; while other phosphatidylcholines, phosphatidylethanolamines, ceramides, and ether-linked phosphatidylethanolamines decreased in early AD. A multivariate approach was developed from some lipid variables, showing high diagnostic indexes (70% sensitivity, 90% specificity, 80% accuracy). From brain and plasma lipidome, some significant correlations were observed, mainly in the glycerophospholipid family. Also, some differences were found in both plasma and brain lipids, according to the estrous cycle phase.
CONCLUSIONS: Therefore, lipid alterations can be identified in plasma at early AD stages in mice females, with a relationship with brain lipid metabolism for most of the lipid subfamilies, suggesting some lipids as potential AD biomarkers. In addition, the estrous cycle monitoring could be relevant in female studies.

UNASSIGNED: To identify biomarkers in human blood or urine at an early stage of knee osteoarthritis (OA) and to elucidate if any can accurately differentiate between healthy controls and early knee OA patients and be considered as a candidate for widespread clinical use for early diagnosis of the disease.
UNASSIGNED: Medline, Embase and Web of Science were screened to identify comparative studies measuring differences in blood or urine biomarkers between healthy controls and knee OA patients at an early stage (grade 1 or 2 Kellgren-Laurence). Two independent reviewers screened the abstracts for eligibility, reviewed the full texts, assessed the methodological quality and extracted the data. The Joanna Briggs Institute critical appraisal tool for diagnostic test accuracy studies was used to assess the quality of the included studies. Due to relevant heterogeneity, meta-analysis was not appropriate.
UNASSIGNED: Five studies met the eligibility criteria. The examined biomarkers were adropin, collagen type II metabolite, C-terminal cross-linked telopeptide of type II collagen, C-terminal cross-linked telopeptide of type I collagen, cartilage oligomeric matrix protein, matrix metalloproteinase 3, N-terminal propeptide of procollagen type IIA, type I procollagen N-terminal propeptides, N-terminal osteocalcin, angiopoietin-2, follistatin, granulocyte colony-stimulating factor, hepatocyte growth factor, interleukin-8, leptin, platelet-derived growth factor-BB, platelet endothelial cell adhesion molecule-1, vascular endothelial growth factor and calprotectin and totalling 19 biomarkers. All of the biomarkers were studied only once in the selected papers.
UNASSIGNED: There is no reliable biomarker available to differentiate between early knee OA in patients and healthy controls, but a potential role of a cluster of biomarkers to close this gap. There are several limitations, including inappropriate study designs, small sample sizes, nonconsecutive patient groups and inadequate statistical methods for evaluating biomarker performance in studies included.
UNASSIGNED: Level III.

Early extubation after pediatric cardiac surgery has come full circle from being practiced in the early days of pediatric cardiac surgery, falling out of favor with opioid-heavy cardiostable anesthesia, and resurfacing again in more recent times as part of enhanced recovery after surgery practice. Early extubation is variably defined, but is mostly accepted as extubation that occurs within 6-8 h from the end of surgery. In recent years, the debate has shifted from early extubation in the intensive care unit to immediate extubation in the operating theatre. In this review, we examined the benefits and pitfalls of early and immediate extubation, factors that influence the success of early extubation, and potential guidelines for practice and implementation.

The aim of this article is to examine the two most commonly used terms to describe the most common sexual disorder, namely premature ejaculation or early ejaculation. The recent recommendations of the French Society of Urology (2023) and the International Society for Sexual Medicine use the term \"premature\". However, the EAU guidelines (2024) report the new terminological definition of the International Classification of Diseases, replacing \"premature\" with \"early\". It was necessary to refer to the etymological definitions of the two terms to distinguish between \"early\" and \"premature\". If the word \"early\" refers to a rapid development that can be desired, the term \"premature\" implies an occurrence before the appropriate time without any control. In our view, the term \'premature\' is more appropriate in this context, as it highlights the uncontrolled and unwanted part of ejaculation.

BACKGROUND: Initiation of feeding after percutaneous endoscopic gastrostomy (PEG) placement has been debated. Randomized controlled trials (RCTs) have been performed on early feeding compared with delayed feeding after PEG placement with varying results. Therefore, a meta-analysis was conducted examining early vs delayed feeding after placement of a PEG.
METHODS: A comprehensive search of databases was conducted in January 2024. Peer-reviewed published RCTs comparing early feeding (≤4 h) with delayed feeding (>4 h) were identified and included in the meta-analysis. Meta-analysis was completed using pooled estimates of overall complications, individual complications, mortality ≤72 h, and number of day 1 significant gastric residual volumes.
RESULTS: Six RCTs (n = 467) were included in the analysis. Comparison of early feeding with delayed feeding after PEG showed no statistically significant differences for overall complications (P = 0.18), mortality ≤72 h (P = 0.3), and number of day 1 significant gastric residual volumes (P = 0.05). No differences were also noted for individual complications, including vomiting, wound infection, bleeding, or diarrhea.
CONCLUSIONS: Feeding ≤4 h after PEG have no differences in minor and major complications compared with that of delayed feeding. Early feeding ≤4 h is safe and should be recommended in future guidelines.

The management of early-stage hepatocellular carcinoma (HCC) is complex, with multiple treatment strategies available. There is a paucity of literature regarding variations in the patterns of care and outcomes between transplant and non-transplant centres. We conducted this real-world multi-centre cohort study in two liver cancer referral centres with an integrated liver transplant program and an additional eight non-transplant HCC referral centres across Australia to identify variation in patterns of care and key survival outcomes. Patients with stage Barcelona Clinic Liver Cancer (BCLC) 0/A HCC, first diagnosed between 1 January 2016 and 31 December 2020, who were managed at a participating site, were included in the study. Patients were excluded if they had a history of prior HCC or if they received upfront liver transplantation. A total of 887 patients were included in the study, with 433 patients managed at a liver cancer centre with a transplant program (LTC) and 454 patients managed at a non-transplant centre (NTC). Management at an LTC did not significantly predict allocation to resection (adjusted OR 0.75, 95% CI 0.50 to 1.11, p = 0.148). However, in those not receiving resection, LTC and NTC patients were systematically managed differently, with LTC patients five times less likely to receive upfront ablation than NTC patients (adjusted OR 0.19, 95% CI 0.13 to 0.28, p < 0.001), even after adjusting for tumour burden, as well as for age, gender, liver disease aetiology, liver disease severity, and medical comorbidities. LTCs exhibited significantly higher proportions of patients undergoing TACE for every tumour burden category, including those with a single tumour measuring 2 cm or less (p < 0.001). Using multivariable Cox proportional hazards analysis, management at a transplant centre was associated with reduced all-cause mortality (adjusted HR 0.71, 95% CI 0.51 to 0.98, p = 0.036), and competing-risk regression analysis, considering liver transplant as a competing event, demonstrated a similar reduction in risk (adjusted HR 0.70, 95% CI 0.50 to 0.99, p = 0.041), suggesting that the reduced risk of death is not fully explained by higher rates of transplantation. Our study highlights systematic differences in HCC care between large volume liver transplant centres and other sites, which has not previously been well-described. Further work is needed to better define the reasons for differences in treatment allocation and to aim to minimise unwarranted treatment variation to maximise patient outcomes across Australia.

OBJECTIVE: Crohn\'s disease (CD) is a progressive disorder leading to cumulative bowel damage. The Lémann index is a validated tool that can help in monitoring the progression of the disease and evaluating the effectiveness of different therapies. Our aim was to describe the main radiological findings in incidentally diagnosed CD and to evaluate bowel damage in this subgroup compared to patients diagnosed at later stages.
METHODS: Patients with an incidental diagnosis of CD during the colorectal cancer screening program were compared to controls with a CD cohort diagnosed after symptomatic onset and matched 1:1 by disease extent. All cross-sectional examinations were centrally read, performing a descriptive analysis of the main findings and calculation of Lémann index.
RESULTS: Thirty-eight patients were included: 19 with preclinical CD (median age 55 years (IQR, 54-62), 53% male, 74% non-smokers; 74% B1 and 26% B2) and 19 matched-controls with symptomatic CD. In those with preclinical CD, the most frequent transmural findings on MRE were contrast enhancement (79%), wall thickening (79%), followed by lymphadenopathy (68%), edema (42%), and increased vascularity (42%). Among those with strictures, controls showed a higher rate of preestenotic dilation (100% vs. 0%, p = 0.01). Bowel damage assessment revealed no statistically significant differences in the Lémann index between preclinical CD and controls (p = 0.95). A statistically significant higher score in the colonic/rectum score was observed (p = 0.014).
CONCLUSIONS: Patients with preclinical CD demonstrate similar radiological findings and degree of bowel damage as new-onset symptomatic CD.

OBJECTIVE: Recent evidence challenges the current standard of offering surgery to patients with ileocaecal Crohn\'s disease (CD) only when they present complications of the disease. The aim of this study was to compare short-term results of patients who underwent primary ileocaecal resection for either inflammatory (luminal disease, earlier in the disease course) or complicated phenotypes, hypothesizing that the latter would be associated with worse postoperative outcomes.
METHODS: A retrospective, multicentre comparative analysis was performed including patients operated on for primary ileocaecal CD at 12 referral centres. Patients were divided into two groups according to indication of surgery for inflammatory (ICD) or complicated (CCD) phenotype. Short-term results were compared.
RESULTS: A total of 2013 patients were included, with 291 (14.5%) in the ICD group. No differences were found between the groups in time from diagnosis to surgery. CCD patients had higher rates of low body mass index, anaemia (40.9% vs. 27%, p < 0.001) and low albumin (11.3% vs. 2.6%, p < 0.001). CCD patients had longer operations, lower rates of laparoscopic approach (84.3% vs. 93.1%, p = 0.001) and higher conversion rates (9.3% vs. 1.9%, p < 0.001). CCD patients had a longer hospital stay and higher postoperative complication rates (26.1% vs. 21.3%, p = 0.083). Anastomotic leakage and reoperations were also more frequent in this group. More patients in the CCD group required an extended bowel resection (14.1% vs. 8.3%, p: 0.017). In multivariate analysis, CCD was associated with prolonged surgery (OR 3.44, p = 0.001) and the requirement for multiple intraoperative procedures (OR 8.39, p = 0.030).
CONCLUSIONS: Indication for surgery in patients who present with an inflammatory phenotype of CD was associated with better outcomes compared with patients operated on for complications of the disease. There was no difference between groups in time from diagnosis to surgery.
