The field of radiology, pathology, and other image-based diagnostics are getting increasingly important and advanced. This indicates a need for advanced image processing technology such as Deep Learning (DL).

Altered circadian rhythmicity of the QT interval predicts mortality in a large real-world academic hospital population.

Objective And Rationale: Small studies have shown that the QT interval follows a circadian rhythm. This finding has never been confirmed in a large real-world hospital population and the clinical meaning of disrupted rhythmicity remains unknown.

Methods: In this cohort study, all consecutive adult patients with at least one 12-lead ECG acquired between 1991 and 2021 were considered.

Three-dimensional assessment of ascending aortic stiffness, motion, and growth in ascending thoracic aortic aneurysm.

Aims: Aortic wall stiffening in ascending thoracic aortic aneurysm (aTAA) is common. However, the spatial and temporal relationships between stiffness, aortic size, and growth in aTAA remain unclear.

Methods And Results: In this single-centre retrospective study, we utilized vascular deformation mapping to extract multi-directional aortic motion, aortic distensibility, and aortic growth in a multi-planar fashion from multi-phasic ECG-gated computed tomography angiograms.

Mapping Trajectories of Gait Recovery in Clinical Stroke Rehabilitation.

Background: How gait changes during the early stages of stoke rehabilitation, and which patient characteristics are associated with these changes is still largely unknown.

Objective: he first objective was to describe the changes in gait during stroke rehabilitation. Secondly, we determined how various patient characteristics were associated with the rate of change of gait over time.

Evaluation of a biomarker for amyotrophic lateral sclerosis derived from a hypomethylated DNA signature of human motor neurons.

Amyotrophic lateral sclerosis (ALS) lacks a specific biomarker, but is defined by relatively selective toxicity to motor neurons (MN). As others have highlighted, this offers an opportunity to develop a sensitive and specific biomarker based on detection of DNA released from dying MN within accessible biofluids. Here we have performed whole genome bisulfite sequencing (WGBS) of iPSC-derived MN from neurologically normal individuals.

A diagnostic host-specific transcriptome response for Mycoplasma pneumoniae pneumonia to guide pediatric patient treatment.

Mycoplasma pneumoniae causes atypical pneumonia in children and young adults. Its lack of a cell wall makes it resistant to beta-lactams, which are the first-line treatment for typical pneumonia. Current diagnostic tests are time-consuming and have low specificity, leading clinicians to administer empirical antibiotics.

Purpose: Adolescent and young adult (AYA) malignant brain tumour (BT) survivors are at risk of adverse health outcomes, which may impact their health-related quality of life (HRQoL). This study aimed to investigate the (1) prevalence of physical and psychological adverse health outcomes, (2) the HRQoL, and (3) the association of adverse health outcomes and HRQoL among long-term AYA-BT survivors. Adverse health outcomes and HRQoL were compared to other AYA cancer (AYAC) survivors.

Pre-emptive treatment for cytomegalovirus viraemia to prevent cytomegalovirus disease in solid organ transplant recipients.

Background: Cytomegalovirus (CMV) is a significant cause of morbidity and death in solid organ transplant recipients. Pre-emptive treatment of patients with CMV viraemia using antiviral agents has been suggested as an alternative to routine prophylaxis to prevent CMV disease. This is an update of a Cochrane review first published in 2006 and updated in 2013.

Vascular ageing manifestations and hypertension in the community.

Objective: To investigate the association between joint manifestations of vascular ageing (VA) and hypertension.

Methods: We used baseline (2008-2012) and follow-up data (up to 2024) from the Paris Prospective Study III, a French cohort of 10,157 participants. Prevalent and incident hypertension were determined at baseline (blood pressure ≥140/90 mmHg or on medication) and at 2, 4, 6, 8 and 10 years of follow-up (self-reported antihypertensive treatment).

Ischemia during exercise stress testing, an indication of coronary vasomotor dysfunction?

Background: Recently it has been suggested that coronary microvascular dysfunction (CMD) may explain the high false-positive rate of exercise electrocardiographic stress testing (EST). However, patients with angina but non-obstructive coronary artery disease (ANOCA) present with a broader spectrum of coronary vasomotor dysfunction (CVDys), namely coronary artery spasm (CAS), CMD or a combination of both. We aim to investigate the diagnostic value of EST for the entire CVDys spectrum.

Identifying genetic differences between bipolar disorder and major depression through multiple genome-wide association analyses.

Background: Accurate diagnosis of bipolar disorder (BPD) is difficult in clinical practice, with an average delay between symptom onset and diagnosis of about 7 years. A depressive episode often precedes the first manic episode, making it difficult to distinguish BPD from unipolar major depressive disorder (MDD).

Aims: We use genome-wide association analyses (GWAS) to identify differential genetic factors and to develop predictors based on polygenic risk scores (PRS) that may aid early differential diagnosis.

INSIGHT: A Tool for Fit-for-Purpose Evaluation and Quality Assessment of Standardized Observational Data Sources for Real World Evidence on Medicine and Vaccine Safety.

Purpose: To describe the development of INSIGHT, a real-world data quality tool to assess completeness, consistency, and fitness-for-purpose of observational health data sources.

Methods: We designed a three-level pipeline with data quality assessments (DQAs) to be performed in ConcePTION Common Data Model (CDM) instances. The pipeline has been coded using R.

Core Concepts: Self-Controlled Designs in Pharmacoepidemiology.

One of the key challenges in pharmacoepidemiological studies is that of uncontrolled confounding, which occurs when confounders are poorly measured, unmeasured or unknown. Self-controlled designs can help address this issue, as their key comparison is not between people, but periods of time within the same person. This controls for all time-stable confounders (genetics) and in the absence of time-varying confounding negates the need for an external control group.

Supervised Exercise for Patients With Metastatic Breast Cancer: A Cost-Utility Analysis Alongside the PREFERABLE-EFFECT Randomized Controlled Trial.

Purpose: To evaluate the cost utility of a 9-month supervised exercise program for patients with metastatic breast cancer (mBC), compared with control (usual care, supplemented with general activity advice and an activity tracker). Evidence on the cost-effectiveness of exercise for patients with mBC is essential for implementation in clinical practice and is currently lacking.

Methods: A cost-utility analysis was performed alongside the multinational PREFERABLE-EFFECT randomized controlled trial, conducted in 8 centers across Europe and Australia.

Increased clonal hematopoiesis in long-term survivors of pediatric hematopoietic cell transplantation.

In pediatric hematopoietic cell transplantation (HCT) recipients, transplanted donor cells may need to function far beyond normal human lifespan. Here, we investigated the risk of clonal hematopoiesis (CH) in 144 pediatric long-term HCT survivors and 258 non-transplanted controls. CH was detected in 16% of HCT recipients and 8% of controls, at variant allele frequencies (VAFs) of 0.

NAB2::STAT6 Rearranged Carcinoma of the Parotid Gland with Sebaceous Differentiation: A Case Report.

Purpose: The NAB2::STAT6 fusion is predominantly associated with solitary fibrous tumors (SFTs) and is utilized in diagnosing SFTs through nuclear STAT6 protein overexpression. Recent studies expanded the phenotypic spectrum of NAB2::STAT6 rearranged neoplasms, including adamantinoma-like and teratocarcinosarcoma-like phenotypes. We report a case of a NAB2::STAT6 rearranged epithelial tumor exhibiting sebaceous differentiation in the parotid gland.

Effect of physical exercise on white matter microstructure in chemotherapy-treated breast cancer patients: a randomized controlled trial (PAM study).

Physical exercise is a promising intervention to improve brain white matter integrity. In the PAM study, exercise intervention effects on white matter integrity were investigated in breast cancer patients. Chemotherapy-treated breast cancer patients with cognitive problems were randomized 2-4 years post-diagnosis to an exercise (n = 91) or control group (n = 90).

Importance of early use of tolvaptan in hyponatremic acutely decompensated heart failure patients, a retrospective study.

Background: Hyponatremia is one of the complicating findings in acute decompensated heart failure. Decrease in cardiac output and systemic blood pressure triggers activation of renin-angiotensin-aldosterone system, antidiuretic hormone, and norepinephrine due to the perceived hypovolemia. Fluid-overloaded heart failure patients are commonly treated with loop diuretics, acutely decompensated heart failure patients tend to be less responsive to conventional oral doses of a loop diuretic, while other different diuretics could work in different part of nephron circulation system.

Low Attainment of Treatment Targets for Cardiovascular Risk Factors in Indonesian Adults With Established Coronary Artery Disease.

Rationale: Established coronary artery disease (CAD) patients are at increased risk for recurrence of cardiovascular events and mortality due to non-attainment of recommended risk factor control targets.

Objective: We aimed to evaluate the attainment of treatment targets for risk factor control among CAD patients as recommended in the Indonesian CVD prevention guidelines.

Methods: Patients were consecutively recruited from the Makassar Cardiac Center at Wahidin Sudirohusodo Hospital, Indonesia.

Imaging flow cytometry reveals divergent mitochondrial phenotypes in mitochondrial disease patients.

Traditional classification by clinical phenotype or oxidative phosphorylation (OXPHOS) complex deficiencies often fails to clarify complex genotype-phenotype correlations in mitochondrial disease. A multimodal functional assessment may better reveal underlying disease patterns. Using imaging flow cytometry (IFC), we evaluated mitochondrial fragmentation, swelling, membrane potential, reactive oxygen species (ROS) production, and mitochondrial mass in fibroblasts from 31 mitochondrial disease patients.

An Overview of Patient-reported Outcomes for Men with Prostate Cancer: Results from the PIONEER Consortium.

Background And Objective: Patient-reported outcome measures (PROMs) are increasingly being used to capture the patients' perspective of their functional status and quality of life (QoL). Big data can help us better understand patient-reported outcomes (PROs). Using prospectively collected data from the Prostate Cancer Diagnosis and Treatment Enhancement Through the Power of Big Data in Europe (PIONEER) consortium, we aimed to describe the functional status and QoL in men with prostate cancer (PCa) treated with active surveillance (AS), radical prostatectomy (RP), and radiotherapy (RT), and to demonstrate the applicability of PROM data on a large scale and at a European level.
