Design and methods of a randomized trial testing "Advancing care for COPD in people living with HIV by implementing evidence-based management through proactive E-consults (ACHIEVE)".

Chronic obstructive pulmonary disease (COPD) is one of the most common comorbid diseases among aging people with HIV (PWH) and is often mismanaged. To address this gap, we are conducting the study, "Advancing care for COPD in people living with HIV by Implementing Evidence-based management through proactive E-consults (ACHIEVE)." This intervention optimizes COPD management by promoting effective, evidence-based care and de-implementing inappropriate therapies for COPD in PWH receiving care at Veteran Affairs (VA) medical centers.

Renal function is a major predictor of circulating acyl-CoA-binding protein/diazepam-binding inhibitor.

Objective: Acyl-CoA-binding protein (ACBP)/diazepam-binding inhibitor has lately been described as an endocrine factor affecting food intake and lipid metabolism. ACBP is dysregulated in catabolic/malnutrition states like sepsis or systemic inflammation. However, regulation of ACBP has not been investigated in conditions with impaired kidney function, so far.

Expert Consensus on the Nephrotoxic Potential of 195 Medications in the Non-intensive Care Setting: A Modified Delphi Method.

Introduction: Nephrotoxin exposure is significantly associated with acute kidney injury (AKI) development. A standardized list of nephrotoxic medications to surveil and their perceived nephrotoxic potential (NxP) does not exist for non-critically ill patients.

Objective: This study generated consensus on the nephrotoxic effect of 195 medications used in the non-intensive care setting.

Antifibrotic Soluble Thy-1 Correlates with Renal Dysfunction in Chronic Kidney Disease.

Kidney fibrosis is a major culprit in the development and progression of chronic kidney disease (CKD), ultimately leading to the irreversible loss of organ function. Thymocyte differentiation antigen-1 (Thy-1) controls many core functions of fibroblasts relevant to fibrogenesis but is also found in a soluble form (sThy-1) in serum and urine. We investigated the association of sThy-1 with clinical parameters in patients with CKD receiving hemodialysis treatment compared to individuals with a preserved renal function.

Limited clinical utility for GWAS or polygenic risk score for postoperative acute kidney injury in non-cardiac surgery in European-ancestry patients.

Background: Prior studies support a genetic basis for postoperative acute kidney injury (AKI). We conducted a genome-wide association study (GWAS), assessed the clinical utility of a polygenic risk score (PRS), and estimated the heritable component of AKI in patients who underwent noncardiac surgery.

Methods: We performed a retrospective large-scale genome-wide association study followed by a meta-analysis of patients who underwent noncardiac surgery at the Vanderbilt University Medical Center ("Vanderbilt" cohort) or Michigan Medicine, the academic medical center of the University of Michigan ("Michigan" cohort).

Survival and kidney recovery among recipients of continuous renal replacement therapy.

Continuous renal replacement therapy (CRRT) is widely used in the care of critically ill patients with acute kidney injury (AKI). Despite hopeful trends suggested by recent studies, mortality among CRRT recipients with severe AKI remains extremely high. Moreover, CRRT does not confer a reduction in mortality in trials comparing CRRT to intermittent RRT modalities.

Achieved blood pressure post-acute kidney injury and risk of adverse outcomes after AKI: A prospective parallel cohort study.

Background: There has recently been considerable interest in better understanding how blood pressure should be managed after an episode of hospitalized AKI, but there are scant data regarding the associations between blood pressure measured after AKI and subsequent adverse outcomes. We hypothesized that among AKI survivors, higher blood pressure measured three months after hospital discharge would be associated with worse outcomes. We also hypothesized these associations between blood pressure and outcomes would be similar among those who survived non-AKI hospitalizations.

Biomarkers of inflammation and repair in kidney disease progression.

INTRODUCTIONAcute kidney injury and chronic kidney disease (CKD) are common in hospitalized patients. To inform clinical decision making, more accurate information regarding risk of long-term progression to kidney failure is required.METHODSWe enrolled 1538 hospitalized patients in a multicenter, prospective cohort study.

Prospective Cohort Study of Renin-Angiotensin System Blocker Usage after Hospitalized Acute Kidney Injury.

Background And Objectives: The risk-benefit ratio of angiotensin-converting enzyme inhibitor or angiotensin receptor blocker therapy after AKI may be altered due to concerns regarding recurrent AKI. We evaluated, in a prospective cohort, the association between use (versus nonuse) of angiotensin-converting enzyme inhibitors/angiotensin receptor blockers and the subsequent risk of AKI and other adverse outcomes after hospitalizations with and without AKI.

Design, Setting, Participants, & Measurements: We studied 1538 patients recently discharged from the hospital who enrolled in the multicenter, prospective ASSESS-AKI study, with approximately half of patients experiencing AKI during the index hospitalization.

The impact of distraction minimization on endoscopic mentoring and performance.

 Endoscopic mentoring requires active attention by the preceptor. Unfortunately, sources of distraction are abundant during endoscopic precepting. The impact of distraction minimization on endoscopic mentoring and performance is unknown.

Integrin β1 Establishes Liver Microstructure and Modulates Transforming Growth Factor β during Liver Development and Regeneration.

A unique and complex microstructure underlies the diverse functions of the liver. Breakdown of this organization, as occurs in fibrosis and cirrhosis, impairs liver function and leads to disease. The role of integrin β1 was examined both in establishing liver microstructure and recreating it after injury.

Implementation of an Intensive Care Unit Diary Program at a Veterans Affairs Hospital.

Background: Intensive care unit (ICU) diaries are recommended to address psychological sequelae following critical illness. Diaries are correlated with reduced prevalence of posttraumatic stress disorder in survivors of critical illness and their families.

Local Problem: Our ICU was not adequately meeting the psychological needs of patients and families.

Focal arrhythmia ablation with multipolar mapping: Does it still make sense to stay off-grid?

Multipolar mapping (MPM) has primarily been studied in complex arrhythmia substrates or reentrant circuits. Chieng et al. use a case-control design to compare MPM and point-by-point mapping with an ablation catheter for focal atrial and ventricular tachycardias, showing reduced procedure times and earlier electrograms in the MPM group but no difference in clinical outcomes.

Pro-neurotensin depends on renal function and is related to all-cause mortality in chronic kidney disease.

Background: Patients with chronic kidney disease (CKD) have a high risk of premature cardiovascular diseases (CVD) and show increased mortality. Pro-neurotensin (Pro-NT) was associated with metabolic diseases and predicted incident CVD and mortality. However, Pro-NT regulation in CKD and its potential role linking CKD and mortality have not been investigated, so far.

Implementation of a Patient and Family-Centered Intensive Care Unit Peer Support Program at a Veterans Affairs Hospital.

Peer support is a novel strategy to mitigate postintensive care syndrome and postintensive care syndrome-family. This project implemented a peer support program to address postintensive care syndrome for patients and family members. Using a free-flow, unstructured format, a chaplain, social worker, nurse, and intensive care unit survivor led veterans and loved ones in discussion of intensive care unit experiences, fears, and the challenges of recovery.

Post-Acute Kidney Injury Proteinuria and Subsequent Kidney Disease Progression: The Assessment, Serial Evaluation, and Subsequent Sequelae in Acute Kidney Injury (ASSESS-AKI) Study.

Importance: Among patients who had acute kidney injury (AKI) during hospitalization, there is a need to improve risk prediction such that those at highest risk for subsequent loss of kidney function are identified for appropriate follow-up.

Objective: To evaluate the association of post-AKI proteinuria with increased risk of future loss of renal function.

Design, Setting, And Participants: The Assessment, Serial Evaluation, and Subsequent Sequelae in Acute Kidney Injury (ASSESS-AKI) Study was a multicenter prospective cohort study including 4 clinical centers in North America included 1538 patients enrolled 3 months after hospital discharge between December 2009 and February 2015.

Impact of AKI on Urinary Protein Excretion: Analysis of Two Prospective Cohorts.

Background: Prior studies of adverse renal consequences of AKI have almost exclusively focused on eGFR changes. Less is known about potential effects of AKI on proteinuria, although proteinuria is perhaps the strongest risk factor for future loss of renal function.

Methods: We studied enrollees from the Assessment, Serial Evaluation, and Subsequent Sequelae of AKI (ASSESS-AKI) study and the subset of the Chronic Renal Insufficiency Cohort (CRIC) study enrollees recruited from Kaiser Permanente Northern California.

The brown fat-secreted adipokine neuregulin 4 is decreased in human and murine chronic kidney disease.

Objective: Neuregulin 4 (NRG4) has recently been introduced as a novel brown adipose tissue (BAT)-secreted adipokine with beneficial metabolic effects in mice. However, regulation of Nrg4 in end-stage kidney disease (ESKD) and type 2 diabetes mellitus (T2DM) has not been elucidated, so far.

Design/methods: Serum NRG4 levels were quantified by ELISA in 60 subjects with ESKD on chronic hemodialysis as compared to 60 subjects with an estimated glomerular filtration rate >50 mL/min/1.

Premature battery depletion due to compromised low-voltage capacitor in a family of defibrillators.

Background: Boston Scientific (Marlborough, MA, USA) implantable cardioverter-defibrillators (ICDs) and cardiac resynchronization therapy defibrillators (CRT-Ds) manufactured between 2008 and 2014 are potentially subject to premature battery depletion through a low-voltage capacitor malfunction occurring as a result of hydrogen buildup within the device. Although some of these devices are currently under advisory, other devices manufactured during this timeframe carry a lower risk of the same malfunction. These same devices are known to have superior longevity in general, and the overall mean lifespan of the devices remains long.

Dynamic signature of lymphangiogenesis during acute kidney injury and chronic kidney disease.

Acute kidney injury (AKI) and chronic kidney disease (CKD) are interconnected syndromes with significant attributable morbidity and mortality. The disturbing trend of increasing incidence and prevalence of these clinical disorders highlights the urgent need for better understanding of the underlying mechanisms that are involved in pathogenesis of these conditions. Lymphangiogenesis and its involvement in various inflammatory conditions is increasingly recognized while its role in AKI and CKD remains to be fully elucidated.
