Novel Dynamic Organ Storage System Enhances Liver Graft Function in a Porcine Donation After Circulatory Death Model.

Donation after circulatory death (DCD) livers face increased risks of critical complications when preserved with static cold storage (SCS). Although machine perfusion (MP) may mitigate these risks, its cost and logistical complexity limit widespread application. We developed the Dynamic Organ Storage System (DOSS), which delivers oxygenated perfusate at 10°C with minimal electrical power requirement and allows real-time effluent sampling in a portable cooler.

Out of the ice age: Preservation of cardiac allografts with a reusable 10 °C cooler.

Objective: Static cold storage with ice has been the mainstay of cardiac donor preservation. Early preclinical data suggest that allograft preservation at 10 °C may be beneficial. We tested this hypothesis by using a static 10 °C storage device to preserve and transport cardiac allografts.

Reversion to sensitivity explains limited transmission of resistance in a hospital pathogen.

Bacterial pathogens that are successful in hospital environments must survive times of intense antibiotic exposure and times of no antibiotic exposure. When these organisms are closely associated with human hosts, they must also transmit from one patient to another for the resistance to spread. The resulting evolutionary dynamics have, in some settings, led to rising levels of resistance in hospitals.

Pancreatic ductal adenocarcinoma: exploring clinicopathological trends and racial disparities in a comprehensive U.S. population-based study.

Introduction: Pancreatic ductal adenocarcinoma (PDAC) is a highly aggressive malignancy about 50% of PDAC are metastatic at presentation. In this study, we evaluated PDAC demographics, annual trend analysis, racial disparities, survival rate, and the role of different treatment modalities in localized and metastatic disease.

Methods: A total of 144,824 cases of PDAC were obtained from the SEER database from 2000 to 2018.

Bromodomain Proteins Epigenetically Regulate the Mitotically Associated lncRNA MANCR in Triple Negative Breast Cancer Cells.

Long non-coding RNA (lncRNA)-mediated control of gene expression contributes to regulation of biological processes that include proliferation and phenotype, as well as compromised expression of genes that are functionally linked to cancer initiation and tumor progression. lncRNAs have emerged as novel targets and biomarkers in breast cancer. We have shown that mitotically associated lncRNA MANCR is expressed in triple-negative breast cancer (TNBC) cells and that it serves a critical role in promoting genome stability and survival in aggressive breast cancer cells.

Developing a cognitive assessment toolkit for primary care: qualitative assessment of providers' needs and perceptions of usability in clinical practice.

Background: Burden of dementia is expected to substantially increase. Early dementia is underdiagnosed in primary care. Given the benefits of active management of dementia, earlier detection in primary care is imperative.

Measuring growth in critically ill neonates and children.

Critical illness increases the risk of malnutrition in both infants and children. Malnutrition risk is multifactorial and includes premorbid factors as well as changes in nutrient metabolism and energy demands during critical illness. Inadequate nutrition has been linked to poor health outcomes and prolonged length of stay in the intensive care unit, demonstrating the importance of both recognizing and addressing malnutrition in this population.

Effect of Exercise Training on Quality of Life, Symptoms, and Functional Status in Advanced-Stage Lung Cancer Patients: A Systematic Review.

Geographic Variation In Effective Contraceptive Use Among Medicaid Recipients In 2018.

Medicaid is the largest payer for publicly funded contraception, serving millions of women across the United States. However, relatively little is known about the extent to which effective contraceptive services vary geographically for Medicaid recipients. This study used national Medicaid claims to assess county-level variation in rates of provision of the most or moderately effective methods of contraception and provision of long-acting reversible contraception (LARC) across forty states and Washington, D.

Training to Enhance the Knowledge and Comfort Level of Emergency Physicians Providing Care for Survivors of Sexual Assault.

Introduction: Although sexual assault (SA) is a substantial public health problem, emergency physicians do not universally undergo continuing education on caring for survivors of SA. The goal of this intervention was to develop a training course that improves physician understanding of trauma-sensitive care in the emergency department and equips physicians with knowledge of the specialized care required to treat SA survivors.

Methods: Thirty-nine attending emergency physicians underwent a 4-hour training on trauma-sensitive care for survivors of SA and completed prequestionnaires and postquestionnaires to assess training efficacy in improving knowledge base and comfort level providing care.

Update on combined heart and liver transplantation: evolving patient selection, improving outcomes, and outstanding questions.

Purpose Of Review: Combined heart and liver transplantation (CHLT) is an uncommon but increasingly performed procedure with rising need as the population who has undergone Fontan palliation for single ventricle physiology grows. This article reviews the current literature to summarize what is known about patient selection and outcomes and highlights the questions that remain.

Recent Findings: Congenital heart disease (CHD) with Fontan-associated liver disease (FALD) has surpassed noncongenital heart disease as the most common indication for CHLT.

Current Understanding of "Mixed Corticomedullary Adrenal Tumor" and an Insight into Genomic Profiling.

Background: Malignant mixed corticomedullary adrenal tumors (MCMTs) are extremely rare, with limited cases reported in the literature. The pathophysiology of malignant MCMTs is not well understood; the most prevailing theories are that it is a composite tumor of embryologically derived mesodermal (adrenal cortex) and neural crest (medulla) origin, perpetuating as two distinct cell lines forming a singular mass. Clinical features and laboratory diagnosis are associated with hypersecretions of the adrenal cortex and medulla.

Epigenetic-Mediated Regulation of Gene Expression for Biological Control and Cancer: Fidelity of Mechanisms Governing the Cell Cycle.

The cell cycle is governed by stringent epigenetic mechanisms that, in response to intrinsic and extrinsic regulatory cues, support fidelity of DNA replication and cell division. We will focus on (1) the complex and interdependent processes that are obligatory for control of proliferation and compromised in cancer, (2) epigenetic and topological domains that are associated with distinct phases of the cell cycle that may be altered in cancer initiation and progression, and (3) the requirement for mitotic bookmarking to maintain intranuclear localization of transcriptional regulatory machinery to reinforce cell identity throughout the cell cycle to prevent malignant transformation.

Epigenetic-Mediated Regulation of Gene Expression for Biological Control and Cancer: Cell and Tissue Structure, Function, and Phenotype.

Epigenetic gene regulatory mechanisms play a central role in the biological control of cell and tissue structure, function, and phenotype. Identification of epigenetic dysregulation in cancer provides mechanistic into tumor initiation and progression and may prove valuable for a variety of clinical applications. We present an overview of epigenetically driven mechanisms that are obligatory for physiological regulation and parameters of epigenetic control that are modified in tumor cells.

LncMIR181A1HG is a novel chromatin-bound epigenetic suppressor of early stage osteogenic lineage commitment.

Bone formation requires osteogenic differentiation of multipotent mesenchymal stromal cells (MSCs) and lineage progression of committed osteoblast precursors. Osteogenic phenotype commitment is epigenetically controlled by genomic (chromatin) and non-genomic (non-coding RNA) mechanisms. Control of osteogenesis by long non-coding RNAs remains a largely unexplored molecular frontier.

Postpartum Contraceptive Use Among US Medicaid Recipients.

This cohort study uses national Medicaid claims data to assess US state variation in effective contraceptive use 60 days post partum.

Monoclonal antibody treatment for COVID-19 in solid organ transplant recipients.

Solid organ transplant (SOT) recipients are at high risk for severe coronavirus disease 2019 (COVID-19). Studies suggest that early intervention with monoclonal antibody (MAB) treatment directed against the SARS-CoV-2 spike protein may reduce the risk of emergency department visits or hospitalization for COVID-19, especially in high-risk patients. Herein, we describe our single-center experience of 93 SOT (50 kidney, 17 liver, 11 lung, nine heart, and six dual-organ) recipients with mild to moderate COVID-19 who were treated with bamlanivimab or casirivimab-imdevimab per emergency use authorization guidelines.

Creation of a Medical Student Training to Improve Comfort Providing Trauma-Informed Care to Sexual Assault Survivors.

Introduction: Sexual violence is a significant public health concern in the United States, affecting as many as one in two women and one in four men. However, few medical schools offer education on trauma-informed communication with patients who disclose sexual assault (SA). The goal of this training was to provide medical students with an understanding of how to empathically respond to SA disclosures, collect pertinent medical information while avoiding retraumatization, and empower patients to feel in control of their care.

The impact of COVID-19 on opioid treatment program (OTP) services: Where do we go from here?

Medication for opioid use disorder (MOUD) services is key to addressing the opioid crisis and COVID-19 has significantly impacted MOUD delivery. The need for social distancing and self-quarantining requires individuals to maintain personal physical space and limits face-to-face interactions, which are required for methadone dispensing and other regulated treatment activities. Mount Sinai Beth Israel, which has one of the largest opioid treatment service (OTP) delivery systems within the United States and included 10 OTP methadone clinics that responded rapidly by implementing procedures to address the additional challenges during the COVID-19 pandemic.
