Advanced Imaging Techniques for Atherosclerosis and Cardiovascular Calcification in Animal Models.

The detection and assessment of atherosclerosis and cardiovascular calcification can inform risk stratification and therapies to reduce cardiovascular morbidity and mortality. In this review, we provide an overview of current and emerging imaging techniques for assessing atherosclerosis and cardiovascular calcification in animal models. Traditional imaging modalities, such as computed tomography (CT) and magnetic resonance imaging (MRI), offer non-invasive approaches of visualizing atherosclerotic calcification in vivo; integration of these techniques with positron emission tomography (PET) imaging adds molecular imaging capabilities, such as detection of metabolically active microcalcifications with F-sodium fluoride.

Incorporating staffing instability in the nursing home Five-Star Staffing Composite.

Staffing is an important indicator of nursing home quality and resident health outcomes. The Five-Star staffing ratings in Nursing Home Care Compare, the report card published by the Centers for Medicare and Medicaid Services, is based on average hours per resident-day and turnover measures. Studies have shown that a new measure of staffing instability, capturing day-to-day staffing variation, is associated with resident outcomes and provides additional information about quality not reflected in the current Five-Star staffing ratings.

Moxibustion.

Moxibustion is an ancient Traditional Chinese Medicine practice used to treat a variety of symptoms and medical conditions. Here we present the case of an elderly patient whose scars from prior moxibustion treatment were initially misdiagnosed as digital ischemia.

Rapid prediction of acute thrombosis via nanoengineered immunosensors with unsupervised clustering for multiple circulating biomarkers.

The recent SARS-CoV-2 pandemic underscores the need for rapid and accurate prediction of clinical thrombotic events. Here, we developed nanoengineered multichannel immunosensors for rapid detection of circulating biomarkers associated with thrombosis, including C-reactive protein (CRP), calprotectin, soluble platelet selectin (sP-selectin), and D-dimer. We fabricated the immunosensors using fiber laser engraving of carbon nanotubes and CO laser cutting of microfluidic channels, along with the electrochemical deposition of gold nanoparticles to conjugate with biomarker-specific aptamers and antibody.

Spanish-speaking Hispanic/Latino families education-related parental involvement practices.

Under current and prominent definitions, the rates of parental involvement among Hispanic/Latino families have been historically low. However, empirical evidence suggests that parental involvement can be perceived/practiced in varied ways. This work explored these perceptions held by Spanish-speaking Hispanic/Latino families through focus groups ( = 10) and individual interviews ( = 23) with parents of school-age children.

Commentary: Ovarian Cancer: Path to Effective Treatments.

Despite advancements in cancer therapeutics such as checkpoint inhibitors and some targeted therapies, we have not achieved success in effectively treating ovarian cancer, since these therapeutics only benefit a subset of patients, and also provide short-term protection. The use of chemotherapy and radiation therapy can cause depletion and/or lack of immune cells' function. Chimeric antigen receptor T (CAR-T) cell therapy is found to be effective against several blood-based cancers, but limited success was seen against solid tumors.

PGC-1α drives small cell neuroendocrine cancer progression toward an ASCL1-expressing subtype with increased mitochondrial capacity.

Adenocarcinomas from multiple tissues can converge to treatment-resistant small cell neuroendocrine (SCN) cancers composed of ASCL1, POU2F3, NEUROD1, and YAP1 subtypes. We investigated how mitochondrial metabolism influences SCN cancer (SCNC) progression. Extensive bioinformatics analyses encompassing thousands of patient tumors and human cancer cell lines uncovered enhanced expression of proliferator-activatedreceptor gamma coactivator 1-alpha (PGC-1α), a potent regulator of mitochondrial oxidative phosphorylation (OXPHOS), across several SCNCs.

Trypsin in pancreatitis: The culprit, a mediator, or epiphenomenon?

Pancreatitis is a common, life-threatening inflammatory disease of the exocrine pancreas. Its pathogenesis remains obscure, and no specific or effective treatment is available. Gallstones and alcohol excess are major etiologies of pancreatitis; in a small portion of patients the disease is hereditary.

Community-Engaged Approaches for Improving the Inclusion of Diverse Communities in a Nutrition Clinical Trial.

Background: Cardiometabolic disease (CMD) disproportionately affects African American/Black (AA) and Latino communities. CMD disparities are exacerbated by their underrepresentation in clinical trials for CMD treatments including nutritional interventions. The study aimed to (1) form a precision nutrition community consultant panel (PNCCP) representative of Latino and AA communities in Los Angeles to identify barriers and facilitators to recruitment and retention of diverse communities into nutrition clinical trials and (2) develop culturally informed strategies to improve trial diversity.

Determining the efficacy of ExThera Seraph100 blood filtration in patients diagnosed with pancreatic cancer through the liquid biopsy.

Background: Cancer becomes lethal as it spreads from the primary site to the rest of the body. Circulating tumor cells (CTCs) are biomarkers of disease progression and have been associated with decreased overall survival. Blood filtration is a novel concept for removing CTCs from circulation to improve patient prognosis.

How initial perceptions of the effectiveness of mind and body complementary and integrative health therapies influence long-term adherence in a pragmatic trial.

Objective: Beliefs and perceptions about pain intervention effectiveness when initiating a therapy may influence long-term engagement. This study examines how early perceived effectiveness of complementary and integrative health therapies impacts long-term engagement in a pragmatic trial context.

Participants: Veterans with chronic musculoskeletal pain participating in a pragmatic trial of provider-delivered complementary and integrative health therapies (acupuncture, chiropractic care, or massage therapy) used alone compared to combining those therapies with self-care therapies (yoga, Tai Chi/Qigong, or meditation).

Do mindfulness interventions cause harm? Findings from the Learning to Apply Mindfulness to Pain (LAMP) Pragmatic Clinical Trial.

Background: Although mindfulness-based interventions (MBIs) are widely used in clinical and nonclinical settings, there has been little systematic study of their potential risks. To address this gap, we examined differences in psychological and physical worsening among participants in the usual care and intervention conditions of a 3-group, randomized pragmatic trial (Learning to Apply Mindfulness to Pain [LAMP]) that tested the effectiveness of 2 approaches to delivering MBIs to patients with chronic pain.

Methods: The sample consisted of 374 male and 334 female patients with chronic pain enrolled in the LAMP trial who completed a 10-week follow-up survey, 61% of whom had a mental health diagnosis.

Carotid Ultrasound.

Carotid ultrasound is the primary noninvasive method for detecting, grading, and monitoring internal carotid artery (ICA) stenosis. Major components of carotid Doppler ultrasound include assessment of ICA stenosis using Doppler velocity criteria, spectral waveform analysis, and assessment of ICA stenosis. Recently, the Intersocietal Accreditation Commission Vascular Testing put forth new modified Society of Radiologists in Ultrasound criteria with a higher peak systolic velocity threshold of 180 cm/s for 50% to 69% ICA stenosis.

Oncogenic Alterations, Race, and Survival in US Veterans with Metastatic Prostate Cancer Undergoing Somatic Tumor Next Generation Sequencing.

Purpose: National guidelines recommend next generation sequencing (NGS) of tumors in patients diagnosed with metastatic prostate cancer (mPCa) to identify potential actionable alterations. We sought to describe the spectrum and frequency of alterations in PCa-related genes and pathways, as well as associations with self-identified race/ethnicity, and overall survival in US Veterans.

Patients And Methods: This retrospective cohort study included Non-Hispanic Black (NHB) and Non-Hispanic white (NHW) Veterans with mPCa who obtained NGS through the Veterans Affairs National Precision Oncology Program.

Patient characteristics and health system encounters of decedents not marked deceased in the electronic health record.

Objectives: Health systems are increasingly accountable for patients and require accurate electronic health record (EHR) vital status. We recently demonstrated that 19% of seriously ill primary care patients in one system were not marked dead in the EHR and 80% of these decedents had an encounter or appointment outstanding after death. Herein we describe the mechanism of identifying decedents whose death is not captured at the level of the EHR, characterize these decedents, and describe medications refilled after death.

Postamputation Pain Management.

Postamputation pain is one of the most common and challenging pain conditions to treat and includes residual limb pain and phantom limb pain. Residual limb pain is present at the amputation site or proximal to the amputation site and may be caused by poor wound healing, poor prosthetic fitting, or neuropathic pain. Phantom limb pain is experienced distal to the amputation site and may be caused by maladaptive supraspinal reorganization.

Pathways to social integration among homeless-experienced adults with serious mental illness: a qualitative perspective.

Background: Social integration (i.e., reciprocal interactions with peers and community members) is a notable challenge for many homeless-experienced adults with serious mental illness (SMI).

Spatiotemporal multilevel joint modeling of longitudinal and survival outcomes in end-stage kidney disease.

Individuals with end-stage kidney disease (ESKD) on dialysis experience high mortality and excessive burden of hospitalizations over time relative to comparable Medicare patient cohorts without kidney failure. A key interest in this population is to understand the time-dynamic effects of multilevel risk factors that contribute to the correlated outcomes of longitudinal hospitalization and mortality. For this we utilize multilevel data from the United States Renal Data System (USRDS), a national database that includes nearly all patients with ESKD, where repeated measurements/hospitalizations over time are nested in patients and patients are nested within (health service) regions across the contiguous U.

ZIP8 A391T Crohn's Disease-Linked Risk Variant Induces Colonic Metal Ion Dyshomeostasis, Microbiome Compositional Shifts, and Inflammation.

Background: The pathogenesis of Crohn's disease involves genetic and environmental factors, with the gut microbiome playing a crucial role. The Crohn's disease-associated variant rs13107325 in the SLC39A8 gene results in an A391T substitution in the ZIP8 metal ion transporter and has previously been linked to alterations in the colonic microbiome in variant carriers. We hypothesized that the A391T substitution alters metal ion homeostasis in the colonic mucosal-luminal interface, thereby inducing dysbiosis which may promote intestinal inflammation.
