Aqueous Metabolite Trends for the Progression of Nonalcoholic Fatty Liver Disease in Female Bariatric Surgery Patients by Targeted H-NMR Metabolomics.

Determining biomarkers and better characterizing the biochemical progression of nonalcoholic fatty liver disease (NAFLD) remains a clinical challenge. A targeted H-NMR study of serum, combined with clinical variables, detected and localized biomarkers to stages of NAFLD in morbidly obese females. Pre-surgery serum samples from 100 middle-aged, morbidly obese female subjects, grouped on gold-standard liver wedge biopsies (non-NAFLD; steatosis; and fibrosis) were collected, extracted, and analyzed in aqueous (DO) buffer (H, 600 MHz).

End-of-Life Plans for African American Older Adults With Dementia.

African Americans are perceived to be least likely of all racial and ethnic groups to prepare for the end of life. However, verbal plans for the end of life are of particular importance to this population and may help understand why they are less likely to possess a formal end-of-life care planning document. The purpose of this study was to determine the number of formal and/or informal end-of-life care plans that existed among a convenience sample of African American older adults with dementia.

Nonuniform sampling by quantiles.

A flexible strategy for choosing samples nonuniformly from a Nyquist grid using the concept of statistical quantiles is presented for broad classes of NMR experimentation. Quantile-directed scheduling is intuitive and flexible for any weighting function, promotes reproducibility and seed independence, and is generalizable to multiple dimensions. In brief, weighting functions are divided into regions of equal probability, which define the samples to be acquired.

Understanding End-of-Life Decision-Making Terminology Among African American Older Adults.

The purpose of the current study was to examine understanding of end-of-life (EOL) decision-making terminology among family caregivers of African American older adults with dementia. This qualitative descriptive study was part of a larger mixed-methods study from which a subset of caregivers (n = 18) completed interviews. Data were analyzed using descriptive statistics and content analyses guided by methods of qualitative analysis.

Evaluation of an office protocol to increase exclusivity of breastfeeding.

Objective: The purpose of this study was to determine whether implementing a program based on a clinical protocol affects breastfeeding rates within a pediatric primary care setting. Increasing breastfeeding rates is an important public health initiative identified by multiple agencies.

Methods: The Academy of Breastfeeding Medicine (ABM) clinical protocol ("The Breastfeeding-Friendly Physician's Office, Part 1: Optimizing Care for Infants and Children") was used as a template for the provision of breastfeeding services within a pediatric primary care clinic.
