  1. Ultra-high dimensional variable selection with application to normative aging study: DNA methylation and metabolic syndrome

    N296wz15f?file=thumbnail
    Description: Metabolic syndrome has become a major public health challenge worldwide. The association between metabolic syndrome and DNA methylation is of great research interest. We constructed a binomial model to investigate the association between a metabolic syndrome index and DNA methylation in the Normative Aging Study. We applied the Iterative Sure...

  2. Preparedness of HIV care and treatment clinics for the management of concomitant non–communicable diseases: a cross–sectional survey

    2j62s4898?file=thumbnail
    Description: In Sub-Saharan Africa, epidemiological studies have reported an increasing burden of non-communicable diseases (NCD) among people living with HIV. NCD management can be feasibly integrated into HIV care; however, clinic readiness to provide NCD services in these settings should first be assessed and gaps in care identified. A cross-sectional survey...

  3. Parental characteristic patterns associated with maintaining healthy physical activity behavior during childhood and adolescence

    Xk81jk39j?file=thumbnail
    Description: Background: Parental characteristics that influence child physical activity (PA) behavior often co-occur. An analytic approach that considers these co-occurring patterns can help researchers better understand the overall context of parental influence. The study aims were to: (1) identify diverse patterns of the relationships among parental characteristics, (2) examine the influence...

  4. Performance-based incentives may be appropriate to address challenges to delivery of prevention of vertical transmission of HIV services in rural Mozambique: a qualitative investigation

    Pk02c975z?file=thumbnail
    Description: Background: Performance-based incentives (PBIs) have garnered global attention as a promising strategy to improve healthcare delivery to vulnerable populations. However, literature gaps in the context in which an intervention is implemented and how the PBIs were developed exist. Therefore, we (1) characterized the barriers and promoters to prevention of vertical...

  5. Obstetrician cognitive and affective skills in a diverse academic population

    6682x3930?file=thumbnail
    Description: Background: Obstetrician cognitive and affective traits have been identified to have relationships with their patients’ perinatal outcomes. The objective was to identify relationships between obstetrician demographic and practice characteristics and physician coping, self-efficacy, anxiety and ambiguity tolerance. Methods: Obstetricians at a single institution were surveyed using 5 validated scales measuring...

  6. Developmental trajectories of physical activity and television viewing during adolescence among girls: National Growth and Health Cohort Study

    Ht24wj41z?file=thumbnail
    Description: Background: Analytic methodology for investigating physical activity patterns over time has been limited. The aim of this study was to demonstrate the group-based trajectory analysis process for identifying developmental physical activity (PA) and television (TV) viewing trajectories and the risk factor of PA trajectories, and for examining a relationship between...

  7. Evolution of anthozoan polyp retraction mechanisms: convergent functional morphology and evolutionary allometry of the marginal musculature in order Zoanthidea (Cnidaria: Anthozoa: Hexacorallia)

    Mc87pq263?file=thumbnail
    Description: Background: Retraction is among the most important basic behaviors of anthozoan Cnidaria polyps and is achieved through the coordinated contraction of at least six different muscle groups. Across the Anthozoa, these muscles range from unrecognizable atrophies to massive hypertrophies, producing a wide diversity of retraction abilities and functional morphologies. The...

  8. Comparison of range-of-motion and variability in upper body movements between transradial prosthesis users and able-bodied controls when executing goal-oriented tasks

    6t053f984?file=thumbnail
    Description: Background: Current upper limb prostheses do not replace the active degrees-of-freedom distal to the elbow inherent to intact physiology. Limited evidence suggests that transradial prosthesis users demonstrate shoulder and trunk movements to compensate for these missing volitional degrees-of-freedom. The purpose of this study was to enhance understanding of the effects...
