Vital Exhaustion and Biomarkers Associated With Cardiovascular Risk: The ARIC Study.

Background: Vital exhaustion, defined as excessive fatigue, demoralization, and irritability due to chronic stress, is independently associated with cardiovascular disease (CVD).

Objectives: The purpose of this study was to examine the association of vital exhaustion with biomarkers associated with CVD risk in the ARIC (Atherosclerosis Risk In Communities) study.

Methods: We examined the cross-sectional association of vital exhaustion (assessed using the Maastricht Vital Exhaustion Questionnaire [MVEQ]) with cardiac biomarker (high-sensitivity troponin T [hs-TnT], N-terminal pro-B-type natriuretic peptide [NT-proBNP]) and high-sensitivity C-reactive protein (hs-CRP) levels in 11,542 ARIC study participants without CVD at ARIC visit 2 using multivariable logistic and linear regression models.

Change in Depressive Symptoms and Longitudinal Regional Amyloid Accumulation in Unimpaired Older Adults.

Importance: Depressive symptoms in older adults may be a harbinger of Alzheimer disease (AD), even in preclinical stages. It is unclear whether worsening depressive symptoms are manifestations of regional distributions of core AD pathology (amyloid) and whether cognitive changes affect this relationship.

Objective: To evaluate whether increasing depressive symptoms are associated with amyloid accumulation in brain regions important for emotional regulation and whether those associations vary by cognitive performance.

Harnessing physical activity monitoring and digital biomarkers of frailty from pendant based wearables to predict chemotherapy resilience in veterans with cancer.

This study evaluated the use of pendant-based wearables for monitoring digital biomarkers of frailty in predicting chemotherapy resilience among 27 veteran cancer patients (average age: 64.6 ± 13.4 years), undergoing bi-weekly chemotherapy.

Corrigendum: Alveolar macrophages in lung cancer: opportunities and challenges.

[This corrects the article DOI: 10.3389/fimmu.2023.

Alveolar macrophages in lung cancer: opportunities challenges.

Alveolar macrophages (AMs) are critical components of the innate defense mechanism in the lung. Nestled tightly within the alveoli, AMs, derived from the yolk-sac or bone marrow, can phagocytose foreign particles, defend the host against pathogens, recycle surfactant, and promptly respond to inhaled noxious stimuli. The behavior of AMs is tightly dependent on the environmental cues whereby infection, chronic inflammation, and associated metabolic changes can repolarize their effector functions in the lungs.

Age-Related Differences in the Contribution of Systolic Blood Pressure and Biomarkers to Cardiovascular Disease Risk Prediction: The Atherosclerosis Risk in Communities (ARIC) Study.

We sought to determine how biomarkers known to be associated with hypertension-induced end-organ injury complement the use of systolic blood pressure (SBP) for cardiovascular disease (CVD) risk prediction at different ages. Using data from visits 2 (1990 to 1992) and 5 (2011 to 2013) of the Atherosclerosis Risk in Communities (ARIC) study, 3 models were used to predict CVD (composite of coronary heart disease, stroke, and heart failure). Model A included traditional risk factors (TRFs) except SBP, model B-TRF plus SBP, and model C-TRF plus biomarkers (high-sensitivity troponin T [hsTnT] and N-terminal pro-B-type natriuretic peptide [NT-proBNP]).

Post-COVID-19 Syndrome Clinical Pathway for the US Veterans Health Administration.

The Department of Veterans Health Affairs (VHA) has launched 22 multispecialty post-COVID-19 clinics across the US for the growing number of veterans experiencing long-term sequelae after acute COVID-19 infection. While evidence-based treatments for this syndrome are under investigation, there is a critical need to establish and disseminate clinical pathways (CPWs) based on knowledge and experience gained in those clinics. This VHA CPW is intended to guide primary care clinicians who care for patients experiencing dyspnea and/or cough during post-COVID-19 syndrome (PCS), which includes symptoms and abnormalities persisting or present beyond 12 weeks of the onset of acute COVID-19.

Contribution of adaptive immunity to human COPD and experimental models of emphysema.

The pathophysiology of chronic obstructive pulmonary disease (COPD) and the undisputed role of innate immune cells in this condition have dominated the field in the basic research arena for many years. Recently, however, compelling data suggesting that adaptive immune cells may also contribute to the progressive nature of lung destruction associated with COPD in smokers have gained considerable attention. The histopathological changes in the lungs of smokers can be limited to the large or small airways, but alveolar loss leading to emphysema, which occurs in some individuals, remains its most significant and irreversible outcome.

State-Level Social Vulnerability Index and Healthcare Access: The Behavioral Risk Factor Surveillance System Survey.

Introduction: Access to health care is affected by social determinants of health. The social vulnerability index encompasses multiple social determinants of health simultaneously and may therefore be associated with healthcare access.

Methods: Cross-sectional data were used from the 2016‒2019 Behavioral Risk Factor Surveillance System, a nationally representative U.

Readmission in Patients With ST-Elevation Myocardial Infarction in 4 Age Groups (<45, >45 to <60, 60 to <75, and >75).

The incidence of ST-elevation myocardial infarction (STEMI) among younger adults is increasing due to an increased prevalence of cardiometabolic risk factors. Readmissions after STEMI in young patients could lead to substantial health care costs and a significant burden on health care resources. Although STEMI readmissions are well studied in elderly patients, limited data are available regarding readmissions after STEMI in young patients and the etiologies remain poorly understood.

Inpatient Coding System and Opportunities for Documentation Optimization: An Interactive Session for Internal Medicine Residents.

Introduction: The Inpatient Prospective Payment System, the framework for categorization of admissions, is based upon physician documentation leading to International Classification of Diseases, Tenth Revision code generation and Medical Severity Diagnosis-Related Group (MS-DRG) assignment. In this curriculum, we introduced internal medicine residents to this inpatient coding framework and its effects on hospital quality metrics and reimbursement. We focused on educating learners about the importance of physicians being proficient in providing thorough and specific clinical documentation to produce appropriate DRG assignment.

In-Stent Restenosis in Saphenous Vein Grafts (from the DIVA Trial).

Saphenous vein grafts (SVGs) have high rates of in-stent restenosis (ISR). We compared the baseline clinical and angiographic characteristics of patients and lesions that did develop ISR with those who did not develop ISR during a median follow-up of 2.7 years in the DIVA study (NCT01121224).

A randomized controlled trial for symptoms of anxiety and depression: Effects of a 1-day acceptance and commitment training workshop.

Background: Cognitive-behavioral therapies often are recommended for anxiety disorders. However, treatment adherence and compliance are major barriers for these treatments, which are often delivered in 10 to 12 sessions over several months. This randomized controlled trial (trial registration NCT02915874 at www.

RNF144A deficiency promotes PD-L1 protein stabilization and carcinogen-induced bladder tumorigenesis.

RNF144A is a DNA damage-induced E3 ubiquitin ligase that targets proteins involved in genome instability for degradation, e.g., DNA-PKcs and BMI1.

INPP4B protects from metabolic syndrome and associated disorders.

A high fat diet and obesity have been linked to the development of metabolic dysfunction and the promotion of multiple cancers. The causative cellular signals are multifactorial and not yet completely understood. In this report, we show that Inositol Polyphosphate-4-Phosphatase Type II B (INPP4B) signaling protects mice from diet-induced metabolic dysfunction.

Targeting the TMPRSS2/ERG fusion mRNA using liposomal nanovectors enhances docetaxel treatment in prostate cancer.

Background: The TMPRSS2/ERG (TE) fusion gene is present in half of the prostate cancers (PCas). The TMPRSS2 and ERG junction of the fusion messenger RNA (mRNA) constitutes a cancer-specific target. Although docetaxel-based chemotherapy is the second line of therapy following development resistance to androgen ablation therapies, it is not curative.

DNA methylation patterns in bladder tumors of African American patients point to distinct alterations in xenobiotic metabolism.

Racial/ethnic disparities have a significant impact on bladder cancer outcomes with African American patients demonstrating inferior survival over European-American patients. We hypothesized that epigenetic difference in methylation of tumor DNA is an underlying cause of this survival health disparity. We analyzed bladder tumors from African American and European-American patients using reduced representation bisulfite sequencing (RRBS) to annotate differentially methylated DNA regions.

State Governments and Judges May Moderate the Impact of the Trump Administration's Promotion of Medicaid Work Requirements.

In January 2018, the Center for Medicare and Medicaid Services (CMS) released guidance that encouraged states to submit Section 1115 waivers that impose work requirements on some Medicaid beneficiaries. To evaluate the potential impact of a policy, we need to accurately predict both how far a policy will spread and how durable it will prove over time. This commentary draws upon recent political science scholarship to describe potential constraints that changes in state-level partisan control can impose on CMS's current waiver strategy, as well as how state-level constraints might interact with judicial review to further limit the policy's spread.

Spatially Restricted Stromal Wnt Signaling Restrains Prostate Epithelial Progenitor Growth through Direct and Indirect Mechanisms.

Cell-autonomous Wnt signaling has well-characterized functions in controlling stem cell activity, including in the prostate. While niche cells secrete Wnt ligands, the effects of Wnt signaling in niche cells per se are less understood. Here, we show that stromal cells in the proximal prostatic duct near the urethra, a mouse prostate stem cell niche, not only produce multiple Wnt ligands but also exhibit strong Wnt/β-catenin activity.

TRAF4-mediated ubiquitination of NGF receptor TrkA regulates prostate cancer metastasis.

Receptor tyrosine kinases (RTKs) are important drivers of cancers. In addition to genomic alterations, aberrant activation of WT RTKs plays an important role in driving cancer progression. However, the mechanisms underlying how RTKs drive prostate cancer remain incompletely characterized.

Fibroblast growth factor receptor signaling plays a key role in transformation induced by the TMPRSS2/ERG fusion gene and decreased PTEN.

Prostate cancer is the most common visceral malignancy and the second leading cause of cancer deaths in US men. Correlative studies in human prostate cancers reveal a frequent association of the TMPRSS2/ERG (TE) fusion gene with loss of PTEN and studies in mouse models reveal that ERG expression and PTEN loss synergistically promote prostate cancer progression. To determine the mechanism by which ERG overexpression and PTEN loss leads to transformation, we overexpressed the TE fusion gene and knocked down PTEN in an immortalized but non-transformed prostate epithelial cell line.

miR-33a is a tumor suppressor microRNA that is decreased in prostate cancer.

Prostate cancer is one of the most frequently diagnosed neoplasms among men worldwide. MicroRNAs (miRNAs) are involved in numerous important cellular processes including proliferation, differentiation and apoptosis. They have been found to be aberrantly expressed in many types of human cancers.

RGS12 Is a Novel Tumor-Suppressor Gene in African American Prostate Cancer That Represses AKT and MNX1 Expression.

African American (AA) men exhibit a relatively high incidence and mortality due to prostate cancer even after adjustment for socioeconomic factors, but the biological basis for this disparity is unclear. Here, we identify a novel region on chromosome 4p16.3 that is lost selectively in AA prostate cancer.
