Received Self-Care Support and Psychosocial Health Among Older Adults with Non-Dialysis-Dependent Chronic Kidney Disease.

Older age is linked with poorer self-care in the chronic kidney disease (CKD) setting. Informal health supporters (family members and friends) are critical sources of self-care support, but much remains unclear about the characteristics and implications of received support among this patient population. We examined how received self-care support (amount and type) related to positive (CKD management self-efficacy) and negative (depressive symptoms) psychosocial health correlates of self-care in 536 adults aged 65 years and older with non-dialysis-dependent CKD.

Association of Genetically Predicted Skipping of COL4A4 Exon 27 with Hematuria and Albuminuria.

Key Points: Using transcriptome-wide association studies, we identified an association between splicing out of exon 27 of COL4A4 and hematuria. We confirmed the presence of COL4A4 exon 27 splicing in an independent cohort. Functional assays revealed that the COL4A4 transcript with exon 27 spliced out affects collagen IV trimer assembly and secretion.

Patient Practices, Perceptions, and Barriers to Self-measurement of Blood Pressure in a Rural Health System.

Background: Self-measurement of blood pressure (SMBP) is endorsed by current guidelines for diagnosing and managing hypertension (HTN). We surveyed individuals in a rural healthcare system on practices and attitudes related to SMBP that could guide future practice.

Methods: Survey questions were sent via an online patient portal to a random sample of 56,275 patients with either BP > 140/90 mm Hg or cardiovascular care in the system.

GWAS for the composite traits of hematuria and albuminuria.

Our GWAS of hematuria in the UK Biobank identified 6 loci, some of which overlap with loci for albuminuria suggesting pleiotropy. Since clinical syndromes are often defined by combinations of traits, generating a combined phenotype can improve power to detect loci influencing multiple characteristics. Thus the composite trait of hematuria and albuminuria was chosen to enrich for glomerular pathologies.

Blockbuster Medications for Obesity: A Primer for Nephrologists.

The prevalence of obesity in the United States and across the world continues to climb, imparting increased risk of chronic disease. This impact is doubly felt in nephrology because obesity not only increases the risk of chronic kidney disease (CKD) but also exacerbates existing cardiovascular morbidity and mortality. The role of medical weight loss therapy in CKD has been debated, but increasing evidence suggests that intentional weight loss is protective against adverse kidney and cardiovascular outcomes.

Individuals heterozygous for ALG8 protein-truncating variants are at increased risk of a mild cystic kidney disease.

ALG8 protein-truncating variants (PTVs) have previously been described in patients with polycystic liver disease and in some cases cystic kidney disease. Given a lack of well-controlled studies, we determined whether individuals heterozygous for ALG8 PTVs are at increased risk of cystic kidney disease in a large, unselected health system-based observational cohort linked to electronic health records in Pennsylvania (Geisinger-Regeneron DiscovEHR MyCode study). Out of 174,172 patients, 236 were identified with ALG8 PTVs.

Exome Sequencing of a Clinical Population for Autosomal Dominant Polycystic Kidney Disease.

Importance: Most studies of autosomal dominant polycystic kidney disease (ADPKD) genetics have used kidney specialty cohorts, focusing on PKD1 and PKD2. These can lead to biased estimates of population prevalence of ADPKD-associated gene variants and their phenotypic expression.

Objective: To determine the prevalence of ADPKD and contributions of PKD1, PKD2, and other genes related to cystic kidney disease in a large, unselected cohort.

Effects of a Dietitian-Led, Telehealth Lifestyle Intervention on Blood Pressure: Results of a Randomized, Controlled Trial.

Background Limited data exist on the benefits of lifestyle behavior change delivered using telehealth and web-based applications with varied support on blood pressure (BP). Methods and Results We conducted a 2-site randomized controlled trial at Geisinger (January 2019-March 2021) to compare the efficacy of 2 remotely delivered strategies using web-based applications in participants with 24-hour systolic BP 120-160 mm Hg and body mass index ≥25 kg/m. Both arms received access to web-based applications and the same lifestyle guidance per American Heart Association guidelines.
