Mental Stress-Induced Change in Plasma Stromal Cell-Derived Factor-1 and Adverse Cardiovascular Outcomes: A Cohort Study.

Background: Acute psychological stress can provoke mental stress-induced myocardial ischemia (MSIMI) in coronary artery disease (CAD). Stromal cell-derived factor 1 (SDF1) is released in response to hypoxia, and higher levels of SDF1 are associated with adverse outcomes. We examined whether an increase in SDF1 level in response to mental stress predicts adverse outcomes in CAD patients.

Quantitation of diffuse myocardial ischemia with mental stress and its association with cardiovascular events in individuals with recent myocardial infarction.

Microcirculatory dysfunction during psychological stress may lead to diffuse myocardial ischemia. We developed a novel quantification method for diffuse ischemia during mental stress (dMSI) and examined its relationship with outcomes after a myocardial infarction (MI). We studied 300 patients ≤ 61 years of age (50% women) with a recent MI.

Therapy-related core binding factor acute myeloid leukemia.

Therapy-related acute myeloid leukemia (t-AML) usually stems from exposure of the bone marrow to cytotoxic chemotherapy and/or radiation therapy. t-AML is usually associated with poor overall survival, but occasionally t-AML can involve favorable-risk cytogenetics, including core binding factor AML (CBF-AML), which shows a recurrent chromosomal rearrangement with t(8;21) (q22;22) and 'inv(16) (p13.1;q22)/t(16;16)(p13.

Perioperative management and surgical field optimization in functional endoscopic sinus surgery.

A sound anesthesiologist-surgeon collaboration is crucial for the success of functional endoscopic sinus surgery (FESS). The aim of this narrative review was to describe if and how anesthetic choice can decrease bleeding and improve visibility in the surgical field (VSF) and thus contribute to successful FESS. A literature search was conducted on evidence-based practices published from 2011 to 2021 describing perioperative care, intravenous/inhalation anesthetics, and operative approaches for FESS and their effects on blood loss and VSF.

Ambulatory blood pressure monitoring in children: A retrospective single-center study.

Objectives: (1) Compare 24-hour ambulatory blood pressure monitoring (ABPM) diagnoses in a pediatric population with the new 2022 guidelines to the original diagnoses with the 2014 guidelines. (2) Determine whether findings of hypertension from ABPM could be predicted from prior patient data. (3) Determine whether ABPM readings could predict left ventricular mass index (LVMI) in patients who obtained an echocardiogram (ECHO).

Ontologies Applied in Clinical Decision Support System Rules: Systematic Review.

Background: Clinical decision support systems (CDSSs) are important for the quality and safety of health care delivery. Although CDSS rules guide CDSS behavior, they are not routinely shared and reused.

Objective: Ontologies have the potential to promote the reuse of CDSS rules.

Phenol neurolysis in people with spinal cord injury: a descriptive study.

Study Design: Descriptive study.

Objectives: The study's main objective was to describe the common targets of phenol neurolysis and review the safety and efficacy of the dose used for this spasticity management procedure in people with spinal cord injury (SCI).

Setting: An acute rehabilitation hospital.

Adar1 deletion causes degeneration of the exocrine pancreas via Mavs-dependent interferon signaling.

Adenosine deaminase acting on RNA 1 (ADAR1) is an RNA-binding protein that deaminates adenosine (A) to inosine (I). A-to-I editing alters post-transcriptional RNA processing, making ADAR1 a crucial regulator of gene expression. Consequently, Adar1 has been implicated in organogenesis.

Factors associated with meeting physical activity guidelines during the COVID-19 pandemic.

Introduction: The COVID-19 pandemic impacted individual physical activity levels. Less is known regarding how factors such as sociodemographic and built environment were associated with physical activity engagement during the pandemic. Understanding these factors is critical to informing future infectious disease mitigation policies that promote, rather than hinder physical activity.

Recurrent Infantile Hypertrophic Pyloric Stenosis in the Emergency Department: A Case Report.

Introduction: Infantile hypertrophic pyloric stenosis (IHPS) is a common cause of infant vomiting. Emergency department (ED) diagnosis is usually made by pyloric ultrasound and treated by pyloromyotomy.

Case Report: An eight-week-old boy with a history of IHPS about six weeks status post pyloromyotomy presented to the ED with vomiting and failure to thrive, and a critically narrowed pylorus was identified by ultrasound.

Therapeutic Management of Chronic Lymphocytic Leukemia Presenting with Recurrent Massive Ascites.

Chronic lymphocytic leukemia (CLL) is a lymphoproliferative malignancy that is categorized by the production and accumulation of CD5+ monoclonal B cell lymphocytes, commonly in the spleen, bone marrow, and peripheral blood; these are morphologically mature lymphocytes with abnormal immune function. Ascites, although common in solid organ malignancies such as ovarian, breast, and gastrointestinal, is a rare clinical manifestation in hematological malignancies. The case presented herein describes an elderly male patient with CLL who presented with transudative ascites 7 years after the completion of chemotherapy.

Creation of an Ex Vivo Renal Perfusion Model to Investigate Microwave Ablation.

This study hypothesized that an ex vivo renal perfusion model can create smaller microwave ablation (MWA) measurements during perfused states compared with nonperfused states across multiple device settings. Nine bovine kidneys, a fluoroscopic compatible perfusion model, and a commercially-available clinical MWA system were used to perform 72 ablations (36 perfused and 36 nonperfused) at 9 different device settings. Comparing perfused and nonperfused ablations at each device setting, significant differences in volume existed for 6 of 9 settings (P < .

Faculty diversity, equity, and inclusion in academic dentistry: Revisiting the past and analyzing the present to create the future.

Aim: In 2021, NIDCR published the landmark report "Oral Health in America." It described that while oral health-related research and care has seen amazing progress, oral health inequities and lack of oral care for large segments of the US population have not improved. This situation plus the predicted increase of the diversification of the US population requires decisive actions to ensure that future dentists will be optimally prepared to provide the best possible care for all patients.

Shoulder Dystocia: Challenging Basic Assumptions.

Most of our knowledge pertaining to this obstetric emergency has emanated from case reports and retrospective studies that have subsequently resulted in empirical management protocols. This article has identified the existence of large gaps in our clinical knowledge base regarding the prevention and resolution of shoulder dystocia, as well as its long-term sequelae. We have attempted to challenge current recommendations regarding whether prophylactic cesarean delivery should be performed based on estimated fetal weight alone or a prior history of shoulder dystocia, shoulder dystocia management techniques, what defines "excessive" traction, and the role of simulation training for all clinicians.

Adipocyte mesenchymal transition contributes to mammary tumor progression.

Obesity is associated with increased cancer incidence and progression. However, the relationship between adiposity and cancer remains poorly understood at the mechanistic level. Here, we report that adipocytes from tumor-invasive mammary fat undergo de-differentiation to fibroblast-like precursor cells during tumor progression and integrate into the tumor microenvironment.

CXCR4 and CXCR7 signaling promotes tumor progression and obesity-associated epithelial-mesenchymal transition in prostate cancer cells.

Obesity is associated with increased prostate cancer (PCa) progression and higher mortality, however, the mechanism(s) remain still unclear. Here, we investigated signaling by the ASC-secreted chemokine CXCL12 in a mouse allograft model of PCa and in HiMyc mice in the context of diet-induced obesity. Treatment of mice with CXCR4 antagonist inhibited CXCL12-induced signaling pathways, tumor growth and EMT in HMVP2 allograft tumors.
