Incidence and Management of Splanchnic Vein Thrombosis in Pancreatic Diseases.

Splanchnic vein thrombosis (SVT) in pancreatic disease has a 20%-30% incidence rate, leading to increased mortality and complication rates. Therefore, the aim of this review is to summarize recent evidence about the incidence, risk factors, and management of pancreatic cancer, pancreatic cystic neoplasm-, and pancreatitis-related SVT. Doppler ultrasound should be the first imaging choice, followed by contrast-enhanced computed tomography or magnetic resonance imaging.

Onset of pancreatic cancer before and after acute pancreatitis: A multicenter longitudinal cohort study.

Background: Pancreatic cancer (PC) is a leading cause of cancer mortality, often diagnosed at advanced stages. Acute pancreatitis (AP), particularly idiopathic cases, may serve as an early indicator of PC.

Objective: This multicenter cohort study investigated the incidence of PC before and after an AP episode, focusing on idiopathic AP and the role of pseudocysts as potential early markers for PC development.

Hemoglobin decrease predicts untoward outcomes better than severity of anemia.

Patients with gastrointestinal bleeding (GIB) exhibit varying tolerances to acute blood loss. We aimed to investigate the effect of relative Hb decrease (ΔHb%) on GIB outcomes. Participants enrolled in the Hungarian GIB Registry between 2019 and 2022 were analyzed.

CT-assessed sarcopenia and immune-related adverse events in patients with lung cancer: A competing risk time-to-event analysis.

Background: Immune checkpoint inhibitors (ICIs) can induce immune-related adverse events (irAEs). This study investigates the relationship between CT-assessed sarcopenia and irAEs in patients with lung cancer who are receiving ICIs.

Methods: Patients were enrolled if they had lung cancer treated with ICIs at the University Medical Center Groningen (2015-2021) and had undergone low-dose CT scans that included the third lumbar vertebral level (L3).

Cardiac surgery with valve replacement temporarily disrupts the hippocampal memory network.

Background: Systemic inflammation after heart valve replacement surgery commonly results in complications including cognitive impairment. This study was designed to investigate whether valvular heart disease itself and inflammation after valve replacement surgery affects cognition and the related functional connectivity (FC) of the hippocampal memory network.

Methods: Forty-three patients with valvular heart disease were screened for recruitment and assessed with cognition function tests, blood inflammatory cytokine measurements, and functional magnetic resonance imaging scans before surgery and on postoperative day 7 and 30.

Comparison of fit and trueness of single-unit and short-span fixed dental restorations fabricated by additive and subtractive manufacturing - A systematic review and meta-analysis.

Objectives: Numerous studies have been conducted on the adaptation of dental restorations fabricated by additive (AM) and subtractive manufacturing (SM); however, the results are conflicting. This systematic review and meta-analysis aimed to evaluate the fit and trueness of fixed restorations made by AM compared to SM.

Data: Studies investigating internal fit, marginal fit, and trueness of fixed prostheses were involved.

Non-Invasive Strategies for Remineralization and Hypersensitivity Management in Molar-Incisor Hypomineralization-A Systematic Review and Meta-Analysis.

Molar-incisor hypomineralization (MIH) is an enamel defect affecting molars and incisors, often leading to hypersensitivity, enamel breakdown, and increased caries risk. Non-invasive treatments, such as casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) and fluoride varnish, show potential in remineralizing affected enamel and reducing sensitivity, but their efficacy is still debated. This study systematically reviews and analyzes the effectiveness of CPP-ACP and other non-invasive agents in improving remineralization and reducing hypersensitivity in MIH-affected teeth.

Cardiovascular PET imaging of fibroblast activation A review of the current literature.

Fibrosis is one of the key healing responses to injury, especially within the heart where it helps to maintain structural integrity following acute insults such as myocardial infarction. However, if it becomes dysregulated then fibrosis can become maladaptive leading to adverse remodelling, impaired cardiac function and heart failure. Fibroblast activation protein is exclusively expressed by activated fibroblasts, the key effector cells of fibrogenesis, and has a unique extracellular domain that is an ideal ligand for novel molecular imaging probes.

Micrognathia and cleft palate as a cause of obstructive sleep apnoea in infants.

Aim: Obstructive sleep apnoea (OSA) is common in Robin sequence (RS). We investigated the significance of micrognathia, cleft palate and sleep positioning on OSA in infants.

Methods: We analysed our 13-year national reference centre polysomnography (PSG) dataset.

Long-Term Risk of Clinically Significant Prostate Cancer in Biopsy-Negative Patients With Baseline Biparametric Prostate MRI.

Background: The long-term prevalence of clinically significant prostate cancer (csPCa) in patients with initial negative prostate biopsy is unknown.

Purpose: To investigate the rate of csPCa of men with initial negative biopsy.

Study Type: Retrospective analysis of prospectively collected data.

Intra-individual radiomic analysis of pericoronary adipose tissue: Photon-counting detector vs energy-integrating detector CT angiography.

Background: The impact of novel photon-counting detector (PCD)-CT technology on in-vivo radiomics is not fully understood. This study aimed to compare the intra-individual stability and reproducibility of pericoronary adipose tissue (PCAT) radiomic features between PCD-CT and energy-integrating detector (EID)-CT in patients undergoing coronary CT angiography (CCTA) on both systems.

Methods: Patients undergoing clinically indicated CCTA on an EID-CT were prospectively enrolled for research PCD-CCTA within 30 days.

Effects of knee joint position on the triceps Suræ torque-size relationship during plantarflexion in healthy young adults.

We determined the effects of knee joint position on the relationship between maximal voluntary contraction (MVC) isometric plantar flexor torque and architectural properties of the plantar flexors measured at rest in healthy young adults. We obtained 3-D reconstructed muscle architecture data of the right plantar flexor muscles of nine physically active males using T1 and DTI MRI sequences with the knee in ∼5° flexion and at rest. Muscle volume, fascicle length, pennation angle, and physiological cross-sectional area were estimated for the medial and lateral gastrocnemius and the soleus muscle.

Linking the microarchitecture of neurotransmitter systems to large-scale MEG resting state networks.

Neuronal oscillations are ubiquitous in brain activity at all scales and their synchronization dynamics are essential for information processing in neuronal systems. The underlying synaptic mechanisms, while mainly based on GABA- and glutamatergic neurotransmission, are influenced by neuromodulatory systems that have highly variable densities of neurotransmitter receptors and transporters across the cortical mantle. How they constrain the network structures of interacting oscillations has remained a central unaddressed question.

Cost-effectiveness of ultrahigh-resolution photon-counting detector coronary CT angiography for the evaluation of stable chest pain.

Background: The increased specificity of ultrahigh-resolution (UHR) photon-counting detector (PCD)-CT over energy-integrating detector (EID)-CT for coronary CT angiography (CCTA) could defer unwarranted downstream tests. The objective of the study was to simulate the cost-effectiveness of UHR CCTA in stable chest pain patients with coronary calcifications.

Methods: A decision and simulation model was developed using Monte Carlo simulations with 1000 bootstrap resamples to estimate the costs associated with PCD-CT in lieu of EID-CT for CCTA and the referral for subsequent testing.

Prognostic and therapeutic implications of low aortic valve calcium score in patients with low gradient aortic stenosis.

Introduction: Low gradient (LG) aortic stenosis (AS) poses a diagnostic challenge. Aortic valve calcium score (AVCS) assessment has emerged as a complementary diagnostic method when echocardiography provides discordant results. However, the diagnostic and prognostic value of AVCS in LGAS has not been thoroughly studied.

Lung imaging methods: indications, strengths and limitations.

Imaging methods are fundamental tools to detect and diagnose lung diseases, monitor their treatment and detect possible complications. Each modality, starting from classical chest radiographs and computed tomography, as well as the ever more popular and easily available thoracic ultrasound, magnetic resonance imaging and nuclear medicine methods, and new techniques such as photon counting computed tomography, radiomics and application of artificial intelligence, has its strong and weak points, which we should be familiar with to properly choose between the methods and interpret their results. In this review, we present the indications, strengths and main limitations of methods for chest imaging.
