Paying to publish: A cross-sectional analysis of article processing charges and journal characteristics among 87 pathology journals.

Article processing charges are increasingly being levied on authors via publication fees to provide open access to readers. These charges may impose challenges to early career physicians seeking to publish research but pathology journal article processing charges have not been investigated to date. We aimed to quantify pathology journal article processing charges and investigate the potential associated factors.

A Scoping Review of the Causal Pathways and Biological Mechanisms Linking Nutrition Exposures and Health Outcomes.

Background/aim: Building on the evidence for multifaceted effects of different nutrients, foods and dietary patterns is a new priority for nutrition science. This review aims to describe the causal pathways and biological mechanisms that elucidate the associations between different nutrition exposures (nutrients, foods and dietary patterns) and health outcomes.

Methods: A scoping review was conducted in two stages: 1) review of nutrition science textbooks; and 2) a review of reviews of empirical literature using a systematic approach to elucidate causal pathways and biological mechanisms for nutrition exposures and health outcomes.

CDS2 expression regulates de novo phosphatidic acid synthesis.

CDS enzymes (CDS1 and 2 in mammals) convert phosphatidic acid (PA) to CDP-DG, an essential intermediate in the de novo synthesis of PI. Genetic deletion of CDS2 in primary mouse macrophages resulted in only modest changes in the steady-state levels of major phospholipid species, including PI, but substantial increases in several species of PA, CDP-DG, DG and TG. Stable isotope labelling experiments employing both 13C6- and 13C6D7-glucose revealed loss of CDS2 resulted in a minimal reduction in the rate of de novo PI synthesis but a substantial increase in the rate of de novo PA synthesis from G3P, derived from DHAP via glycolysis.

Improving the Lives of People with Sickle Cell Disease: Community Organizations and Epidemiologists Working Together.

Background: The Centers for Disease Control and Prevention's Sickle Cell Data Collection (SCDC) program comprises multidisciplinary teams, which include community-based organizations. Partnering with community-based organizations (CBOs) is a novel approach to ensure that SCDC data are actionable.

Objective: To better understand areas for mutual capacity building, we explored the relationships and dynamics between CBO and data teams within the SCDC program in 10 states.

Ableism and the discourse of risk and safety in patient-facing work-integrated learning.

In many countries, such as Canada, the USA, England, and Australia, to graduate from a regulated profession such as nursing, students must complete a set of work-integrated learning (WIL) hours and demonstrate their ability to safely perform physical skills and apply knowledge in relation to professional standards. For a disabled nursing student (DNS) undergoing training in higher education institutions (HEI), securing proper accommodations to participate effectively in WIL experiences has been difficult due to concerns related to risks to self and patient safety. This study used critical discourse analysis to investigate the framing of risk and safety in association with providing DNS with accommodation in WIL.

Providing red blood cells to facilitate organ transplant via normothermic perfusion techniques: A single-center experience.

Background: Normothermic regional perfusion (NRP) and normothermic machine perfusion (NMP) are organ procurement and transport techniques that can improve organ quality, facilitate longer transport, and reduce postoperative complications, increasing organ availability and improving outcomes. NRP and NMP often require allogeneic red blood cells (RBCs). Our academic transfusion service began providing RBCs to support NRP and NMP for adult heart transplant (HT), orthotopic liver transplant (OLT), and multiorgan transplant (MOT) in August 2020.

The seasonal distribution of immune thrombotic thrombocytopenic purpura is influenced by geography: Epidemiologic findings from a multi-center analysis of 719 disease episodes.

Prior studies have suggested that immune thrombotic thrombocytopenic purpura (iTTP) may display seasonal variation; however, methodologic limitations and sample sizes have diminished the ability to perform a rigorous assessment. This 5-year retrospective study assessed the epidemiology of iTTP and determined whether it displays a seasonal pattern. Patients with both initial and relapsed iTTP (defined as a disintegrin and metalloprotease with thrombospondin type motifs 13 activity <10%) from 24 tertiary centers in Australia, Canada, France, Greece, Italy, Spain, and the US were included.

Pro-atherogenic medical conditions are associated with widespread regional brain metabolite abnormalities in those with alcohol use disorder.

Aims: Widespread brain metabolite abnormalities in those with alcohol use disorder (AUD) were reported in numerous studies, but the effects of the pro-atherogenic conditions of hypertension, type 2 diabetes mellitus, hepatitis C seropositivity, and hyperlipidemia on metabolite levels were not considered. These conditions were associated with brain metabolite abnormalities in those without AUD. We predicted treatment-seeking individuals with AUD and pro-atherogenic conditions (Atherogenic+) demonstrate lower regional metabolite markers of neuronal viability [N-acetylaspartate (NAA)] and cell membrane turnover/synthesis [choline-containing compounds (Cho)], compared with those with AUD without pro-atherogenic conditions (Atherogenic-) and healthy controls (CON).

RhD-Alloimmunization in Adult and Pediatric Trauma Patients.

The actual risk of providing RhD-positive units to RhD-negative recipients remains debatable. There is no standard of care in the United States (US) to guide transfusion decisions regarding RhD type for patients with an unknown blood type, except for women of childbearing age and neonates. The risk of alloantibody formation by an RhD-negative patient exposed to RhD-positive blood is reported to be from 3% to 70%.

Frontal Brain N-Acetylaspartate at Treatment Entry is Related to Future WHO Risk Drinking Levels in Individuals with Alcohol Use Disorder.

Objective: To assess the viability of regional brain metabolite levels of individuals with alcohol use disorder (AUD) at treatment entry as a biomarker of post-treatment levels of alcohol use, categorized according to the World Health Organization risk drinking levels (WHO-RDL).

Method: Eighty-five individuals initiating treatment for AUD (16 ± 13 days after last alcohol consumption), and 45 light/non-drinking controls (LN) completed a 1.5T proton multislice magnetic resonance spectroscopic imaging study.

The LCLAT1/LYCAT acyltransferase is required for EGF-mediated phosphatidylinositol-3,4,5-trisphosphate generation and Akt signaling.

Receptor tyrosine kinases such as EGF receptor (EGFR) stimulate phosphoinositide 3 kinases to convert phosphatidylinositol-4,5-bisphosophate [PtdIns(4,5)P] into phosphatidylinositol-3,4,5-trisphosphate [PtdIns(3,4,5)P]. PtdIns(3,4,5)P then remodels actin and gene expression, and boosts cell survival and proliferation. PtdIns(3,4,5)P partly achieves these functions by triggering activation of the kinase Akt, which phosphorylates targets like Tsc2 and GSK3β.

Phospholipase Cγ regulates lacrimal gland branching by competing with PI3K in phosphoinositide metabolism.

Although the regulation of branching morphogenesis by spatially distributed cues is well established, the role of intracellular signaling in determining the branching pattern remains poorly understood. In this study, we investigated the regulation and function of phospholipase C gamma (PLCγ) in Fibroblast Growth Factor (FGF) signaling in lacrimal gland development. We showed that deletion of in the lacrimal gland epithelium leads to ectopic branching and acinar hyperplasia, which was phenocopied by either mutating the PLCγ1 binding site on Fgfr2 or disabling any of its SH2 domains.

Capturing the perspectives of African American informal dementia caregivers: a phenomenological study.

Dementia can be overwhelming to families and their caregivers. Informal caregiving is a widespread mode of providing dementia care in African American communities, yet impact of caregiving on informal or family caregivers in African American communities is burdensome. This study aimed to describe the lived experiences of informal caregivers of African American People Living with Dementia (PLWD) to understand their perceptions of dementia and dementia care, caregiver support needs, and service needs.

Transfusion Support in Hematopoietic Stem Cell Transplantation: A Contemporary Narrative Review.

Hematopoietic stem cell transplantation (HSCT) is a cornerstone of modern medical practice, and can only be performed safely and effectively with appropriate transfusion medicine support. Patients undergoing HSCT often develop therapy-related cytopenia, necessitating differing blood product requirements in the pre-, peri-, and post-transplant periods. Moreover, ensuring optimal management for patients alloimmunized to human leukocyte antigens (HLA) and/or red blood cell (RBC) antigens, as well as for patients receiving ABO-incompatible transplants, requires close collaboration with transfusion medicine and blood bank professionals.
