Tricuspid Regurgitation after Orthotopic Heart Transplantation: Trajectories and Association With Mortality.

Background: Tricuspid regurgitation (TR) is common immediately after orthotopic heart transplantation (OHT), though the expected outcomes of TR over time remain undefined. In this study, we examined the natural trajectory of TR in the first 120 days post-transplantation. We observed the clinical phenotypes of trajectories of TR after OHT, and assessed trajectory correlation with 1-year mortality and degree of right ventricular (RV) dysfunction.

Diverging paths: Modeling the relation between adverse effects, attitudes, perceived adherence, and treatment effect in an internet-based cognitive-behavioral intervention for obsessive-compulsive disorder.

Background And Aim: The efficacy of internet-based interventions (IBI) for various psychiatric disorders is widely established, but little is known about the mechanisms or possible influencing factors. One of the most prominent problems in IBI is low adherence, but the relationship between adherence and level of improvement is still unclear. Patients' attitudes and beliefs about IBI as well as the experience of adverse effects-another widely neglected topic-may also influence the effectiveness of these interventions.

Rise of the machines: Normothermic regional perfusion use in heart transplantation in the United States.

Background: Normothermic regional perfusion (NRP) and direct procurement and perfusion (DPP) allow for transplantation with donation after circulatory death (DCD) hearts. This study aimed to characterize the use of and variations in NRP and DPP for DCD transplants in the United States.

Methods: Heart transplants performed between December 1, 2019 and March 31, 2024, were identified from the United Network for Organ Sharing database.

MAIT cell plasticity enables functional adaptation that drives antibacterial immune protection.

Mucosal-associated invariant T (MAIT) cells are known for their rapid effector functions and antibacterial immune protection. Here, we define the plasticity of interferon-γ (IFN-γ)-producing MAIT1 and interleukin-17A (IL-17A)-producing MAIT17 cell subsets in vivo. Whereas T-bet MAIT1 cells remained stable in all experimental settings, after adoptive transfer or acute or infection, RORγt MAIT17 cells could undergo phenotypic and functional conversion into both RORγtT-bet MAIT1/17 and RORγtT-bet MAIT1 cells.

Association between white matter integrity and lower limb motor impairment after stroke: A systematic review: White matter integrity and lower limb motor impairment after stroke.

Background: There is no clear consensus on the anatomical substrates required for recovery from lower limb (LL) impairment after stroke. Knowledge of biomarkers, such as white matter integrity (WMI), could fill this knowledge gap.

Objectives: To analyze the associations between WMI of the corticospinal tract (CST) and corticoreticulospinal pathway (CRP) and LL motor impairment after stroke, in terms of synergistic control and muscle strength.

Heterogeneous Formation of DNA Double-Strand Breaks and Cell-Free DNA in Leukemia T-Cell Line and Human Peripheral Blood Mononuclear Cells in Response to Topoisomerase II Inhibitors.

Background: Improving precision medicine in chemotherapy requires highly sensitive and easily applicable diagnostic tools. In addition, non-invasive molecular real-time monitoring of cytotoxic response is highly desirable. Here, we employed the kinetics of DNA double-strand breaks (DSB) and cell-free DNA (cfDNA) in a cell model of topoisomerase II-inhibitors in T cell leukemia (Jurkat cells) compared to normal cells (peripheral blood mononuclear cells, PBMCs).

Are standing balance and walking ability deficits poststroke related to the integrity of the corticospinal and non-corticospinal tracts? A meta-analysis.

Background: The importance of corticospinal tract (CST) integrity in upper limb recovery poststroke is well established, but its association with standing balance and walking remains unclear. This meta-analysis aimed to establish the relationship between CST and non-CST motor tract integrity, and clinical scores of standing balance and walking poststroke.

Methods: In July 2024, five databases were searched for studies, focusing on diffusion MRI metrics and clinical scores of standing balance and/or walking independence poststroke.

Damsel: analysis and visualisation of DamID sequencing in R.

Summary: DamID sequencing is a technique to map the genome-wide interaction of a protein with DNA. Damsel is the first Bioconductor package to provide an end to end analysis for DamID sequencing data within R. Damsel performs quantification and testing of significant binding sites along with exploratory and visual analysis.

Regional variation in donation after circulatory death heart allograft utilization.

Objective: Randomized data support transplantation of hearts from donors after circulatory death. This may lead to a sizeable increase in the donor pool. Regional variations in donors after circulatory death heart use were examined to help elucidate barriers to donor pool expansion.

[Update from d-uo: what can healthcare research contribute to renal cell carcinoma?].

Background: Renal cell carcinoma (RCC) accounts for about 13.5% of all urological tumors. Healthcare research analyzes whether treatment recommendations from controlled studies or guidelines are being implemented in routine care.

Evaluating Seismocardiography as a Non-Exercise Method for Estimating Maximal Oxygen Uptake.

Background: The value of maximal oxygen uptake (VO) is a key health indicator. Usually, VO is determined with cardiopulmonary exercise testing (CPET), which is cumbersome and time-consuming, making it impractical in many testing scenarios. The aim of this study is to validate a novel seismocardiography sensor (Seismofit, VentriJect DK, Hellerup, Denmark) for non-exercise estimation of VO.

Leaftronics: Natural lignocellulose scaffolds for sustainable electronics.

The global rise in electronic waste is alarming, driven by the persistent use of glass, epoxy, and plastic substrates owing to their cost, stability, flexibility, and transparency. This underscores the need for biodegradable alternatives with similar properties. This study shows that leaf-derived lignocellulose scaffolds can stabilize bio-sourced, solution-processed polymers by acting as natural sequestering media.

Audit of Antimicrobial Prescribing Trends in 1447 Outpatient Wound Assessments: Baseline Rates and Impact of Bacterial Fluorescence Imaging.

In the field of wound care, the prescription of antibiotics and antimicrobials is haphazard and irrational, which has led to unchecked overprescribing. Recent Joint Commission guidelines mandate that hospital outpatient clinics develop and implement antimicrobial stewardship programs (ASPs). Yet few ASPs exist in wound clinics across the United States (US).

Halogen Bonding in N-Alkyl-Bromo-/Lodo-Pyridinium Salts and its Application in Chromatography.

The alkylation of 3-/4-bromo- and -iodopyridine with methyl triflate smoothly affords the corresponding N-methylpyridinium triflate salts. An anion exchange with NaI or [PPh]Y (Y=Cl, Br, I) yields the corresponding halide salts. Most of them could be structurally characterized and their strong halogen bonds were investigated.

Late follow-up for a randomized trial of surgical treatment of tricuspid valve regurgitation in patients undergoing left ventricular assist device implantation.

Background: We previously reported that concurrent tricuspid valve surgery (TVS) was not associated with a lower incidence of early right heart failure (RHF) in patients undergoing durable left ventricular assist device (LVAD) implantation. This follow-up analysis aimed to further define the clinical impact of concurrent TVS after 2 months of follow-up.

Methods: Patients with moderate or severe tricuspid regurgitation (TR) on preoperative echocardiography (n = 71) were randomized to LVAD implantation either alone (no TVS group; n = 34) or with concurrent TVS (TVS group; n = 37).

TO INFORM OR NOT TO INFORM about venous thromboembolisms - A qualitative study on communication between healthcare professionals and patients with lung cancer.

Background: Venous thromboembolism (VTE) is a leading cause of death among cancer patients. Despite this, studies show that patients with cancer feel inadequately informed about the VTE risk and symptoms, which may impede their ability to recognise symptoms and react promptly. Patients with lung cancer are especially vulnerable due to a high relative risk of developing VTE combined with a high prevalence of low health literacy.

Obstetric anesthesia management of dilated cardiomyopathies and heart failure: a narrative review.

Pregnancy in patients with dilated cardiomyopathy carries a significantly increased risk of maternal mortality or severe morbidity, and pregnancy is typically considered contraindicated for patients with severely reduced ventricular function. Nonetheless, anesthesiologists will still encounter patients with cardiomyopathy requiring delivery or termination care. This review describes how NT-ProBNP testing and echocardiography can help with early recognition of heart failure in pregnancy, and describes a suggested approach to anesthetic management of patients with cardiomyopathies or acute heart failure, including hemodynamic goals, use of vasoactive medications and mechanical support.
