Examining Predictors of Nutritional Risk among Older Adults: A Needs Assessment.

Older adults are the fastest growing population in the United States. This group is at risk for developing chronic diseases resulting from high nutritional risk. The objective of this study was to assess nutritional risks and their key predictors among older adults.

Adapting a Nutrition Education Curriculum for Spanish-Speaking Adults Experiencing Low-Income: Recommendations from Key Stakeholders.

The purpose of this study was to understand recommendations of key stakeholders regarding cultural adaptation of an evidence-based nutrition and physical activity education curriculum for Spanish-speaking adults. Findings from focus groups with Spanish-speaking adults (n=43) and telephone interviews with experts in Spanish nutrition and health education (n=9) revealed: 1) emphasis of the heterogeneity of Spanish-speaking communities; 2) importance of including family in nutrition education; 3) importance of addressing cultural differences between Spanish-speaking and general United States culture; and 4) tips for engaging Spanish-speaking adults in health education. These findings were used to inform cultural adaptation of a nutrition education curriculum.

pH dependent membrane binding of the Solanum tuberosum plant specific insert: An in silico study.

The Solanum tuberosum plant-specific insert (StPSI) has been shown to possess potent antimicrobial activity against both human and plant pathogens. Furthermore, in vitro, the StPSI is capable of fusing phospholipid vesicles, provided the conditions of net anionic vesicle charge and acidic pH are met. Constant pH replica-exchange simulations indicate several acidic residues on the dimer have highly perturbed pKs (<3.

Soft Vibrational Modes Predict Breaking Events during Force-Induced Protein Unfolding.

We investigate the correlation between soft vibrational modes and unfolding events in simulated force spectroscopy of proteins. Unfolding trajectories are obtained from molecular dynamics simulations of a Gō model of a monomer of a mutant of superoxide dismutase 1 protein containing all heavy atoms in the protein, and a normal mode analysis is performed based on the anisotropic network model. We show that a softness map constructed from the superposition of the amplitudes of localized soft modes correlates with unfolding events at different stages of the unfolding process.

The unfolding mechanism of monomeric mutant SOD1 by simulated force spectroscopy.

Mechanical unfolding of mutated apo, disulfide-reduced, monomeric superoxide dismutase 1 protein (SOD1) has been simulated via force spectroscopy techniques, using both an all-atom (AA), explicit solvent model and a coarse-grained heavy-atom Gō (HA-Gō) model. The HA-Gō model was implemented at two different pulling speeds for comparison. The most-common sequence of unfolding in the AA model agrees well with the most-common unfolding sequence of the HA-Gō model, when the same normalized pulling rate was used.

Use of Videoconferencing for Lactation Consultation: An Online Cross-Sectional Survey of Mothers' Acceptance in the United States.

Background: Suboptimal breastfeeding duration and exclusivity rates are a public health concern. Therefore, there is a need for identifying effective tools for use in interventions targeting specific barriers to optimal breastfeeding outcomes. Research aim: This study aimed to assess the relationship between acceptance of remote lactation consultation using videoconferencing and (a) maternal demographic factors, (b) technology acceptance subscales, (c) maternal learning style preferences, and (d) other potentially explanatory maternal factors.

As Simple As Possible, but Not Simpler: Exploring the Fidelity of Coarse-Grained Protein Models for Simulated Force Spectroscopy.

Mechanical unfolding of a single domain of loop-truncated superoxide dismutase protein has been simulated via force spectroscopy techniques with both all-atom (AA) models and several coarse-grained models having different levels of resolution: A Gō model containing all heavy atoms in the protein (HA-Gō), the associative memory, water mediated, structure and energy model (AWSEM) which has 3 interaction sites per amino acid, and a Gō model containing only one interaction site per amino acid at the Cα position (Cα-Gō). To systematically compare results across models, the scales of time, energy, and force had to be suitably renormalized in each model. Surprisingly, the HA-Gō model gives the softest protein, exhibiting much smaller force peaks than all other models after the above renormalization.

Comparing the prognosis of those with initial shockable and non-shockable rhythms with increasing durations of CPR: Informing minimum durations of resuscitation.

Aim: There is little data to inform the appropriate duration of resuscitation attempts for out-of-hospital cardiac arrest (OHCA). We assessed the relationship of elapsed duration since commencement of resuscitation and outcomes, highlighting differences between initial shockable and non-shockable rhythms.

Methods: We examined consecutive adult non-traumatic EMS-treated OHCA in a single health region.

Breastfeeding knowledge, attitudes, prior exposure, and intent among undergraduate students.

Background: Understanding breastfeeding knowledge, attitudes, and exposures among nonpregnant youth who are likely to be future parents may provide significant pathways to successfully increasing breastfeeding as the normal, accepted way of feeding infants. However, based on a recent review of the literature, only 3 studies have assessed these factors in nonpregnant, young adults in the United States in the past 10 years.

Objective: The objective of this study was to gather more recent data regarding breastfeeding knowledge, attitudes, and prior exposure among undergraduate university students.

Remote lactation consultation: a qualitative study of maternal response to experience and recommendations for survey development.

Background: Use of videoconferencing technology for healthcare intervention and support is an area of tremendous potential, especially in regard to application in rural or underserved communities. Potential for cost-savings, time-savings, and increased access to care are the ultimate driving force behind use of this technology, for both providers and recipients of healthcare services. Recently, the Federal Government has initiated rulings to support the increased use of computer technology in underserved areas.

Caregiver- vs infant-oriented feeding: a model of infant-feeding strategies among special supplemental nutrition program for women, infants, and children participants in rural east Tennessee.

The aim of this project was to collect data from focus-group participants to inform the future development of region-specific educational strategies to modify infant-feeding practices that may predispose children to obesity. Infant-feeding perceptions and practices were collected from participants of the Special Supplemental Nutrition Program for Women, Infants, and Children, through recorded focus groups, in two East Tennessee counties. Focus groups replaced the participants' required, prescheduled nutrition-education classes for participants with infants younger than 6 months of age.
