FLT3-TKD Measurable Residual Disease Detection Using Droplet Digital PCR and Clinical Applications in Acute Myeloid Leukemia.

The tyrosine kinase domain of the FMS-Like tyrosine kinase 3 (-TKD) is recurrently mutated in acute myeloid leukemia (AML). Common molecular techniques used in its detection include PCR and capillary electrophoresis, Sanger sequencing and next-generation sequencing with recognized sensitivity limitations. This study aims to validate the use of droplet digital PCR (ddPCR) in the detection of measurable residual disease (MRD) involving the common -TKD mutations (D835Y, D835H, D835V, D835E).

Glucocorticoid prescribing in neurology.

Glucocorticoids are commonly used for neurological disorders, but they can have significant adverse effects, including adrenal insufficiency, hyperglycaemia, osteoporosis and increased infection risk. Long-term use of corticosteroids requires the prescriber to plan risk mitigation, including monitoring and often coprescribing. This article highlights the potential risks of corticosteroid prescribing and draws together up-to-date guidance with multispecialty input to clarify ways of reducing those risks.

Growth factor-induced activation of MSK2 leads to phosphorylation of H3K9me2S10 and corresponding changes in gene expression.

Extracellular signals are transmitted through kinase cascades to modulate gene expression, but it remains unclear how epigenetic changes regulate this response. Here, we provide evidence that growth factor-stimulated changes in the transcript levels of many responsive genes are accompanied by increases in histone phosphorylation levels, specifically at histone H3 serine-10 when the adjacent lysine-9 is dimethylated (H3K9me2S10). Imaging and proteomic approaches show that epidermal growth factor (EGF) stimulation results in H3K9me2S10 phosphorylation, which occurs in genomic regions enriched for regulatory enhancers of EGF-responsive genes.

High-dose atorvastatin therapy progressively decreases skeletal muscle mitochondrial respiratory capacity in humans.

BACKGROUNDWhile the benefits of statin therapy on atherosclerotic cardiovascular disease are clear, patients often experience mild to moderate skeletal myopathic symptoms, the mechanism for which is unknown. This study investigated the potential effect of high-dose atorvastatin therapy on skeletal muscle mitochondrial function and whole-body aerobic capacity in humans.METHODSEight overweight (BMI, 31.

Experiences of implementing the 'Making Every Contact Count' initiative into a UK integrated care system: an interview study.

Background: The 'Making Every Contact Count' (MECC) approach is in line with the current National Health Service (NHS) strategy to improve and prevent health conditions in England. Despite its importance and value for preventative healthcare, implementation of MECC varies. The aim of this study was to explore the barriers and facilitators of implementing MECC and MECC training into an integrated care system (ICS).

Circulating trans fatty acids are associated with prostate cancer in Ghanaian and American men.

The association between fatty acids and prostate cancer remains poorly explored in African-descent populations. Here, we analyze 24 circulating fatty acids in 2934 men, including 1431 prostate cancer cases and 1503 population controls from Ghana and the United States, using CLIA-certified mass spectrometry-based assays. We investigate their associations with population groups (Ghanaian, African American, European American men), lifestyle factors, the fatty acid desaturase (FADS) genetic locus, and prostate cancer.

Systemic Inflammation Indices and Association with Prostate Cancer Survival in a Diverse Patient Cohort.

There is a lack of investigations assessing the performance of systemic inflammation indices as outcome predictive tools in African Americans with prostate cancer. This study aims to assess the relationships between neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), systemic immune-inflammation (SII), and systemic inflammation response index (SIRI) with survival outcomes among 680 diverse men with prostate cancer. Routine blood results were collected from self-identified African American and European American patients.

The YGetIt? Program: A Mobile Application, PEEP, and Digital Comic Intervention to Improve HIV Care Outcomes for Young Adults.

Introduction: In New York State (NYS), young adults account for the largest number of new human immunodeficiency virus (HIV) infections and struggle to seek and remain in HIV care. Digital interventions and access to peer support have demonstrated positive influences on the HIV care continuum and health outcomes. The New York State Department of Health (NYS DOH) developed YGetIt? (YGI) that combines a mobile application, GET!, peer navigation (PEEPs), and a compelling digital comic series, "Tested," to facilitate the timely entry of young people into HIV care, to prevent vulnerable youth from dropping out of care, and to achieve sustained viral load suppression among those in care.

PRR14 organizes H3K9me3-modified heterochromatin at the nuclear lamina.

The eukaryotic genome is organized in three dimensions within the nucleus. Transcriptionally active chromatin is spatially separated from silent heterochromatin, a large fraction of which is located at the nuclear periphery. However, the mechanisms by which chromatin is localized at the nuclear periphery remain poorly understood.

Effectiveness of physical rehabilitation in improving physical functioning and quality of life for long-term-care residents with dementia: a systematic review protocol.

Objective: The objective of this review is to evaluate the effectiveness of physical rehabilitation versus non-rehabilitation control in improving physical functioning and quality of life in long-term care residents with dementia.

Introduction: Many long-term-care residents live with dementia and have impaired physical function and poor quality of life. Physical rehabilitation can improve physical function and quality of life for people living with dementia, yet many long-term-care residents with dementia do not receive this intervention, and health care providers are unsure of which rehabilitation interventions are effective.

Impact of Heroin and HIV on Gut Integrity and Immune Activation.

Background: Altered gut integrity is central to HIV-related immune activation. Opioids may promote similar changes in gut permeability and/or increase systemic inflammation, potentially augmenting processes already occurring in people with HIV (PWH).

Setting: Urban hospital systems in Cleveland, Ohio, and surrounding communities.

Evaluation of Disease Severity and Molecular Relationships Between Isolates on Species in New Hampshire.

Quinoa is a potential new crop for New England; however, its susceptibility to downy mildew, caused by , is a key obstacle for cultivation. The objectives of this study were to evaluate differential resistance within the genus, identify novel sources of resistance for use in future genetic studies or breeding programs, and investigate phylogenetic relationships of isolates from different hosts. The long-term goal of this research is to develop a resistant variety of quinoa to be grown in New England.

BRD4 orchestrates genome folding to promote neural crest differentiation.

Higher-order chromatin structure regulates gene expression, and mutations in proteins mediating genome folding underlie developmental disorders known as cohesinopathies. However, the relationship between three-dimensional genome organization and embryonic development remains unclear. Here we define a role for bromodomain-containing protein 4 (BRD4) in genome folding, and leverage it to understand the importance of genome folding in neural crest progenitor differentiation.

Global chromatin relabeling accompanies spatial inversion of chromatin in rod photoreceptors.

The nuclear architecture of rod photoreceptor cells in nocturnal mammals is unlike that of other animal cells. Murine rod cells have an “inverted” chromatin organization with euchromatin at the nuclear periphery and heterochromatin packed in the center of the nucleus. In conventional nuclear architecture, euchromatin is mostly in the interior, and heterochromatin is largely at the nuclear periphery.

Part 2: New Graduate Nurse Transition Into the Intensive Care Unit: Summative Insights From a Longitudinal Mixed-Methods Study.

Background And Purpose: To address the nursing shortage, it is increasingly common for hospitals to hire new graduate nurses into intensive care units (ICU). New graduates in intensive care likely experience needs beyond those of their peers outside of critical care contexts. Yet, relatively little is known about the experiences of this unique population.

Urinary PGE-M in Men with Prostate Cancer.

Urinary PGE-M is a stable metabolite of prostaglandin E2 (PGE2). PGE2 is a product of the inflammatory COX signaling pathway and has been associated with cancer incidence and metastasis. Its synthesis can be inhibited by aspirin.

Urinary Thromboxane B2 and Lethal Prostate Cancer in African American Men.

Background: Thromboxane A2 (TXA2) is a platelet- and cyclooxygenase-derived eicosanoid that has been linked to metastasis. We investigated the role of TXA2 in the development of lethal prostate cancer in African American (AA) and European American (EA) men.

Methods: We measured urinary 11-dehydrothromboxane B2 (TXB2), a stable metabolite of TXA2, with mass spectrometry.

The nuclear periphery is a scaffold for tissue-specific enhancers.

Nuclear architecture influences gene regulation and cell identity by controlling the three-dimensional organization of genes and their distal regulatory sequences, which may be far apart in linear space. The genome is functionally and spatially segregated in the eukaryotic nucleus with transcriptionally active regions in the nuclear interior separated from repressive regions, including those at the nuclear periphery. Here, we describe the identification of a novel type of nuclear peripheral chromatin domain that is enriched for tissue-specific transcriptional enhancers.

Genetically increasing flux through β-oxidation in skeletal muscle increases mitochondrial reductive stress and glucose intolerance.

Elevated mitochondrial hydrogen peroxide (HO) emission and an oxidative shift in cytosolic redox environment have been linked to high-fat-diet-induced insulin resistance in skeletal muscle. To test specifically whether increased flux through mitochondrial fatty acid oxidation, in the absence of elevated energy demand, directly alters mitochondrial function and redox state in muscle, two genetic models characterized by increased muscle β-oxidation flux were studied. In mice overexpressing peroxisome proliferator-activated receptor-α in muscle (MCK-PPARα), lipid-supported mitochondrial respiration, membrane potential (ΔΨ), and HO production rate (HO) were increased, which coincided with a more oxidized cytosolic redox environment, reduced muscle glucose uptake, and whole body glucose intolerance despite an increased rate of energy expenditure.

Histone methyltransferase activity programs nuclear peripheral genome positioning.

Spatial organization of the genome in the nucleus plays a critical role in development and regulation of transcription. A genomic region that resides at the nuclear periphery is part of the chromatin layer marked with histone H3 lysine 9 dimethyl (H3K9me2), but chromatin reorganization during cell differentiation can cause movement in and out of this nuclear compartment with patterns specific for individual cell fates. Here we describe a CRISPR-based system that allows visualization coupled with forced spatial relocalization of a target genomic locus in live cells.

Assessing Training Interests of Latin American and Caribbean Immigrant-serving HIV/AIDS, STD, and Hepatitis C Providers in New York State, United States.

Healthcare providers may be ill-equipped to address the specific care needs of refugee/immigrant (RI) patient populations. We assessed continuing education (CE) training interests among HIV/AIDS, STD, and Hepatitis C (HASH) providers in New York State (NYS), United States, who serve RI patients from Latin America and the Caribbean (LAC). An online survey was completed by 156 HASH providers during a three-month period in Spring 2018.
