Additionally, a system for recording and mapping biopsy samples has been devised to facilitate sharing of spatial information.

Involvement of tumor immune microenvironment metabolic reprogramming in colorectal cancer progression, immune escape, and response to immunotherapy.

Metabolic reprogramming is a k`ey hallmark of tumors, developed in response to hypoxia and nutrient deficiency during tumor progression. In both cancer and immune cells, there is a metabolic shift from oxidative phosphorylation (OXPHOS) to aerobic glycolysis, also known as the Warburg effect, which then leads to lactate acidification, increased lipid synthesis, and glutaminolysis. This reprogramming facilitates tumor immune evasion and, within the tumor microenvironment (TME), cancer and immune cells collaborate to create a suppressive tumor immune microenvironment (TIME).

Cord blood transfusions in extremely low gestational age neonates to reduce severe retinopathy of prematurity: results of a prespecified interim analysis of the randomized BORN trial.

Background: Preterm infants are at high risk for retinopathy of prematurity (ROP), with potential life-long visual impairment. Low fetal hemoglobin (HbF) levels predict ROP. It is unknown if preventing the HbF decrease also reduces ROP.

The Role of the Autonomic Nervous System in Epilepsy and Migraine: A Narrative Review.

Autonomic symptoms may be local and general clinical manifestations of both epilepsy and migraine caused by the dysfunction of brain areas best known as the central autonomic network. Despite their prevalence, autonomic signs are often misdiagnosed and their treatment is undervalued. This review aims to describe the autonomic manifestations reported during seizures and migraineur attacks according to their presentation, focusing on the role of the central autonomic network (CAN) and on the parasympathetic outflow that often-induced cranial autonomic symptoms (CAS) during migraineur attacks.

Network meta-analysis of adjuvant chemotherapy in biliary tract cancers: Setting the scene for new randomized evidence.

Background And Aims: The best adjuvant chemotherapy for resected biliary tract cancer (BTC) is under debate, with capecitabine supported by weak evidence. Aim of this network meta-analysis is to estimate the efficacy of different phase II/III regimens, comparing monotherapies (gemcitabine or fluoropyrimidines) head-to-head, against observation and combination regimens.

Methods: A comprehensive literature search was conducted on PubMed and EMBASE for phase II/III randomized clinical trials (RCTs) available as of December 2023, reporting hazard ratios (HRs) of overall survival (OS) and event-free survival (EFS).

Integrating Augmented Reality in Spine Surgery: Redefining Precision with New Technologies.

Introduction: The integration of augmented reality (AR) in spine surgery marks a significant advancement, enhancing surgical precision and patient outcomes. AR provides immersive, three-dimensional visualizations of anatomical structures, facilitating meticulous planning and execution of spine surgeries. This technology not only improves spatial understanding and real-time navigation during procedures but also aims to reduce surgical invasiveness and operative times.

Few-Shot Conditional Learning: Automatic and Reliable Device Classification for Medical Test Equipment.

The limited availability of specialized image databases (particularly in hospitals, where tools vary between providers) makes it difficult to train deep learning models. This paper presents a few-shot learning methodology that uses a pre-trained ResNet integrated with an encoder as a backbone to encode conditional shape information for the classification of neonatal resuscitation equipment from less than 100 natural images. The model is also strengthened by incorporating a reliability score, which enriches the prediction with an estimation of classification reliability.

Prokineticin-2 Is Highly Expressed in Colonic Mucosa of Early Parkinson's Disease Patients.

Background: Elevated levels of prokineticin-2 (PK2), regarded as a protein involved in modulating immune/inflammatory responses, have been detected in the substantia nigra, serum, and olfactory neurons of Parkinson's disease (PD) patients. Of note, emerging evidence suggests that gut alterations, including dysbiosis and enteric inflammation, play a role in PD via the gut-brain axis.

Objectives: Our goal was to investigate the expression of PK2 in colonic biopsies of PD patients.

Hepatectomy versus systemic therapy for liver-limited BRAF V600E-mutated colorectal liver metastases: multicentre retrospective study.

Background: To date, only two studies have compared the outcomes of patients with liver-limited BRAF V600E-mutated colorectal liver metastases (CRLMs) managed with resection versus systemic therapy alone, and these have reported contradictory findings.

Methods: In this observational, international, multicentre study, patients with liver-limited BRAF V600E-mutated CRLMs treated with resection or systemic therapy alone were identified from institutional databases. Patterns of recurrence/progression and overall survival were compared using multivariable analyses of the entire cohort and a propensity score-matched cohort.

Transthoracic and transoesophageal echocardiography for tricuspid transcatheter edge-to-edge repair: a step-by-step protocol.

Tricuspid regurgitation (TR) carries an unfavourable prognosis and often leads to progressive right ventricular (RV) failure. Secondary TR accounts for over 90% of cases and is caused by RV and/or tricuspid annulus dilation, in the setting of left heart disease or pulmonary hypertension. Surgical treatment for isolated TR entails a high operative risk and is seldom performed.
