Association of the Cervical Canal Area With Disability and Progression in People With Multiple Sclerosis.

Background And Objectives: In multiple sclerosis (MS), brain reserve serves as a protective factor against cognitive impairment. Previous research has suggested a structural counterpart in the spine-spinal cord reserve-seemed to be associated with physical disability. This study aimed to investigate the potential of the cervical canal area (CCaA) as a proxy for spinal cord reserve in a multicentric cohort of people with MS (PwMS).

Single-center experience of extended brain-death donor heart preservation with the organ care system.

Background: The Organ Care System (OCS) (Transmedics, Andover, MA) reduces cold ischemic time of donor hearts by producing a normothermic beating state during ex vivo perfusion, enabling extended ex situ intervals, which potentially increases donor pool. We aimed to compare outcomes in utilization of OCS and conventional cold storage technique.

Methods: Consecutive heart transplants following brain death at our institution between May 2022 and July 2023 were analyzed.

The Impact of Ipsilateral Implantable Cardioverter Defibrillator in Axillary Intra-Aortic Balloon Pump Support as Bridge to Heart Transplantation.

Background: The axillary artery (AX) access for intra-aortic balloon pump (IABP) as a bridge to heart transplant (HT) allows mobility while awaiting a suitable donor. As end-stage heart failure patients often have an implantable cardioverter defibrillator (ICD) on the left side, the left AX approach may be avoided due to the perception of difficult access and proximity of two devices. We aimed to evaluate the outcomes of patients bridged to HT with a left-sided AX IABP with or without ipsilateral ICDs.

Outpatient Continuous Intravenous Inotropy in the Modern Era.

The use of continuous inotropy in patients with advanced heart failure (HF) has been historically controversial due to the prevailing notion that it will increase mortality. In practice, clinicians have continued to revisit this idea as there remains a lack of treatment options for patients in stage D HF. Clinical trials in the past have generally not shown favorable effects of long-term chronic infusions of positive IV inotropic agents on symptoms and exercise tolerance.

Coronavirus Disease 2019 (COVID-19) in Heart Transplant Recipients and Anti-SARS-CoV-2 Monoclonal Antibodies: Experience, Lessons Learnt, and Future Challenges.

Solid organ transplant recipients (SOTRs), including heart transplant (HT) recipients, infected with Coronavirus disease 2019 (COVID-19) are at higher risk of hospitalization, mechanical ventilation, or death when compared with general population. Advances in diagnosis and treatment of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection have reduced COVID-19-related mortality rates from ~30% in the early pandemic to <3% in 2022 among HT recipients. We performed a retrospective chart review including adult HT recipients at Westchester Medical Center from January 1, 2020 to December 10, 2022, who received anti-SARS-CoV-2 monoclonal antibodies (mAbs) for treatment of mild-to-moderate COVID-19, and those who received tixagevimab/cilgavimab for preexposure prophylaxis.

A generalizable deep voxel-guided morphometry algorithm for the detection of subtle lesion dynamics in multiple sclerosis.

Introduction: Multiple sclerosis (MS) is a chronic neurological disorder characterized by the progressive loss of myelin and axonal structures in the central nervous system. Accurate detection and monitoring of MS-related changes in brain structures are crucial for disease management and treatment evaluation. We propose a deep learning algorithm for creating Voxel-Guided Morphometry (VGM) maps from longitudinal MRI brain volumes for analyzing MS disease activity.

Implementation of a piritramide based patient-controlled analgesia (PCA) as a standard of care for pain control in late abortion induction: A prospective cohort study from a patient perspective.

Objective: To assess whether the implementation of patient-controlled analgesia (PCA) with piritramide using an automatic pump system under routine conditions is effective to reduce pain in late abortion inductions.

Study Design: Prospective observational cohort study.

Setting: Patients requiring medically indicated abortion induction from 14 weeks of pregnancy onwards between July 2019 and July 2020 at the department of Obstetrics and Prenatal Medicine of the Bonn University Hospital in Germany.

White matter changes measured by multi-component MR Fingerprinting in multiple sclerosis.

T-hyperintense lesions are the key imaging marker of multiple sclerosis (MS). Previous studies have shown that the white matter surrounding such lesions is often also affected by MS. Our aim was to develop a new method to visualize and quantify the extent of white matter tissue changes in MS based on relaxometry properties.

Myeloid cell iron uptake pathways and paramagnetic rim formation in multiple sclerosis.

In multiple sclerosis (MS), sustained inflammatory activity can be visualized by iron-sensitive magnetic resonance imaging (MRI) at the edges of chronic lesions. These paramagnetic rim lesions (PRLs) are associated with clinical worsening, although the cell type-specific and molecular pathways of iron uptake and metabolism are not well known. We studied two postmortem cohorts: an exploratory formalin-fixed paraffin-embedded (FFPE) tissue cohort of 18 controls and 24 MS cases and a confirmatory snap-frozen cohort of 6 controls and 14 MS cases.

High-Risk Pulmonary Hypertension Does Not Worsen Outcomes in Heart Transplantation.

Pulmonary hypertension (PH) is a relative contraindication to heart transplantation (HT). Multiple studies showed increased mortality in patients with PH. Advances in care may have led to improved outcomes in the modern era.

Impella devices: a comprehensive review of their development, use, and impact on cardiogenic shock and high-risk percutaneous coronary intervention.

Introduction: Impella devices have emerged as a critical tool for temporary mechanical circulatory support (TMCS) in the management of cardiogenic shock (CS) and high-risk percutaneous coronary interventions (PCI). The purpose of this review is to examine the history of the different Impella devices, their hemodynamic profiles, and how the data supports their use.

Areas Covered: This review covers the development and specifications of the Impella 2.

Short-term brain atrophy evolution after initiation of immunotherapy in a real-world multiple sclerosis cohort.

Background And Purpose: In multiple sclerosis (MS), brain atrophy measurements have emerged as an important biomarker reflecting neurodegeneration and disability progression. However, due to several potential confounders, investigation of brain atrophy in clinical routine and even in controlled clinical studies can be challenging. The aim of this study was to investigate the short-term dynamics of brain atrophy development after initiation of disease-modifying therapy (DMT) in a "real-world setting.

Evolution of concomitant use of veno-arterial extracorporeal membrane oxygenation support with Impella in cardiogenic shock: From percutaneous femoral Impella to axillary Impella 5.5.

Background: Little is known about safety and efficacy of the use of Impella 5.5 compared to previous iterations in the setting of Impella with Veno-Arterial Extracorporeal Membrane Oxygenation Support as ECPELLA.

Methods: Consecutive patients who were treated by ECPELLA with surgically implanted axillary Impella 5.

Cerebrospinal fluid-related tissue damage in multiple sclerosis patients with iron rim lesions.

Background: In multiple sclerosis (MS), iron rim lesions (IRLs) are associated with pronounced tissue damage, higher disease severity and have been suggested as an imaging marker of chronic active inflammation behind the blood-brain barrier indicating progression. Furthermore, chronic intrathecal compartmentalized inflammation has been suggested to be a mediator of a cerebrospinal fluid (CSF)-related tissue damage.

Objective: To investigate CSF markers of intrathecal inflammation in patients with at least one IRL compared to patients without IRLs and to investigate tissue damage in lesions and normal-appearing white matter (NAWM) with proximity to CSF spaces.

Emerging Modalities for Temporary Mechanical Circulatory Support in Cardiogenic Shock.

Cardiogenic shock (CS) is a life-threatening medical condition that requires prompt recognition and treatment. The use of standardized CS criteria, such as the Society for Cardiovascular Angiography and Interventions criteria, can categorize patients and guide therapeutic strategies. Temporary mechanical circulatory support (MCS) devices have become valuable tools in the treatment of CS, as they can provide cardiovascular support as a bridge to recovery, cardiac surgery, or advanced therapies such as cardiac transplant or durable ventricular assist devices.

A diagnostic support system based on pain drawings: binary and k-disease classification of EDS, GBS, FSHD, PROMM, and a control group with Pain2D.

Background And Objective: The diagnosis of rare diseases (RDs) is often challenging due to their rarity, variability and the high number of individual RDs, resulting in a delay in diagnosis with adverse effects for patients and healthcare systems. The development of computer assisted diagnostic decision support systems could help to improve these problems by supporting differential diagnosis and by prompting physicians to initiate the right diagnostic tests. Towards this end, we developed, trained and tested a machine learning model implemented as part of the software called Pain2D to classify four rare diseases (EDS, GBS, FSHD and PROMM), as well as a control group of unspecific chronic pain, from pen-and-paper pain drawings filled in by patients.

An Update on the Diagnosis and Management of Acute Right Heart Failure.

Right ventricular (RV) dysfunction and resultant acute right heart failure (ARHF) is a rapidly growing field of interest, driven by increasing appreciation of its contribution to heart failure morbidity and mortality. Understanding of ARHF pathophysiology has advanced dramatically over recent years and can be broadly described as RV dysfunction related to acute changes in RV afterload, contractility, preload, or left ventricular dysfunction. There are several diagnostic clinical signs and symptoms as well as imaging and hemodynamic assessments that can provide insight into the degree of RV dysfunction.

Ex Vivo Heart Perfusion for Cardiac Transplantation Allowing for Prolonged Perfusion Time and Extension of Distance Traveled for Procurement of Donor Hearts: An Initial Experience in the United States.

Unlabelled: Scarcity of donor hearts continues to be a challenge for heart transplantation (HT). The recently Food and Drug Administration-approved Organ Care System (OCS; Heart, TransMedics) for ex vivo organ perfusion enables extension of ex situ intervals and thus may expand the donor pool. Because postapproval real-world outcomes of OCS in HT are lacking, we report our initial experience.

Pharmacotherapies in Heart Failure With Preserved Ejection Fraction: A Systematic Review and Network Meta-Analysis.

Various pharmacotherapies exist for heart failure with preserved ejection fraction (HFpEF), but with unclear comparative efficacy. We searched EMBASE, Medline, and Cochrane Library from inception through August 2021 for all randomized clinical trials in HFpEF (EF >40%) that evaluated beta-blockers, mineralocorticoid receptor antagonist (MRA), angiotensin-converting enzyme inhibitors (ACE), angiotensin receptor blockers (ARB), angiotensin receptor-neprilysin inhibitor (ARNI), and sodium-glucose cotransporter-2 inhibitors (SGLT2i). Outcomes assessed were cardiovascular mortality, all-cause mortality, and HF hospitalization.

COVID-19, Heart Failure Hospitalizations, and Outcomes: A Nationwide Analysis.

Heart Failure (HF) patients are at a higher risk of adverse events associated with Coronavirus disease 2019 (COVID-19). Large population-based reports of the impact of COVID-19 on patients hospitalized with HF are limited. The National Inpatient Sample database was queried for HF admissions during 2020 in the United States (US), with and without a diagnosis of COVID-19 based on ICD-10-CM U07.

Cannulation-related adverse events of peripheral veno-arterial extracorporeal membrane oxygenation support in heart transplantation: Axillary versus femoral artery cannulation.

Background: In heart transplantation (HT), peripheral veno-arterial extracorporeal membranous oxygenation (VA-ECMO) is utilized preoperatively as a direct bridge to HT or postoperatively for primary graft dysfunction (PGD). Little is known about wound complications of an arterial VA-ECMO cannulation site which can be fatal.

Methods: From 2009 to 2021, outcomes of 80 HT recipients who were supported with peripheral VA-ECMO either preoperatively or postoperatively were compared based on the site of arterial cannulation: axillary (AX: N = 49) versus femoral artery (FA: N = 31).
