Understanding parental choices related to infant sleep practices in the United States using a mixed methods approach.

Background: This study aimed to gather information about parental practices, knowledge, and attitudes regarding infant sleep habits and environments, among families who practice non-recommended sleep practices.

Methods: We conducted one-on-one phone interviews with parents who had practiced non-recommended sleep methods with their infant and had or had not experienced an undesirable sleep event such as a fall. Interviews were recorded and coded with MAXQDA software.

Qualitative Findings from a Pilot Trial of Mindfulness for Low Sexual Desire in Midlife and Older Women.

Low libido is a common and potentially distressing problem among midlife and older women. We recently reported results from a pilot randomized controlled trial of a mindfulness intervention for midlife and older cisgender women with low libido; the purpose of this qualitative investigation is to illustrate women's experiences with being recruited for, enrolling in, and participating in the trial. We conducted individual interviews with a subset of trial participants, some of whom attended a group-based mindfulness intervention and some attended an educational control group (N = 25).

Proinsulin C-peptide is a major source of HLA-DQ8 restricted hybrid insulin peptides recognized by human islet-infiltrating CD4 T cells.

Type 1 diabetes (T1D) is an autoimmune disease that develops when T cells destroy the insulin-producing beta cells that reside in the pancreatic islets. Immune cells, including T cells, infiltrate the islets and gradually destroy the beta cells. Human islet-infiltrating CD4 T cells recognize peptide epitopes derived from proinsulin, particularly C-peptide.

A minority of proliferating human CD4 T cells in antigen-driven proliferation assays are antigen specific.

Antigen-driven T-cell proliferation is often measured using fluorescent dye dilution assays, such as the CFSE-based proliferation assay. Dye dilution assays have been powerful tools to detect human CD4 T-cell responses, particularly against autoantigens. However, it is not known how many cells within the proliferating population are specific for the stimulating antigen.

Kidney hyperfiltration and mitochondrial changes are associated with eGFR decline in young people with type 1 diabetes.

Objectives: To examine the relationship between kidney hyperfiltration during adolescence and subsequent changes in estimated glomerular filtration rate (eGFR) and urinary albumin creatinine ratio (UACR) in a young cohort of participants with type 1 diabetes. Additionally, to explore urinary mitochondrial DNA:nuclear DNA ratio (mtDNA:nDNA) as a marker of metabolic stress and its association with early changes in kidney function.

Methods: Eighty adolescents were studied at baseline [mean (SD) age 14.
