BACKGROUND: Although incidental coronary artery calcium (CAC) has been established as a surrogate measure for atherosclerotic plaque burden, little is known about its progression and the associated risks. This study looks at the association of select cardiovascular risk factors with the progression of CAC over a 2-year period and the relationship between CAC progression and experiencing a composite cardiovascular disease (CVD) event. METHODS: Repeated CAC measurements were obtained for 311 asymptomatic participants aged >44 years, who were recruited from a collaborative network of primary care clinics...

OBJECTIVE: Short sleep duration has been linked with a wide array of poor mental and physical health outcomes. Such risks, however, may be moderated by demographic factors such as gender and race/ethnicity. In a diverse community sample, the current study examined the relationship between gender, race/ethnicity and objectively measured sleep duration, controlling for select potential confounds. METHODS: Participants were 300 community adults (50% female), aged 21 to 70 years, and included 60% non-Hispanic Whites, 15% non-Hispanic Blacks, 19% Hispanic/Latino, and 6% other...

INTRODUCTION: The risk of stillbirth associated with maternal obesity increases with gestational age, however it is unclear if earlier delivery reduces the overall perinatal mortality rate. Our objective was to compare the risk of perinatal mortality associated with each additional week of expectant management to that of immediate delivery. METHODS: This was a retrospective cohort study of singleton nonanomalous births in Texas between 2006 and 2011. Analyses were stratified based on maternal prepregnancy BMI class...

Map-based gene cloning is a vital strategy for the identification of the quantitative trait loci or genes underlying important agronomic traits. The conventional map-based cloning method is powerful but generally time-consuming and labor-intensive. In this context, we introduce an improved bulked segregant analysis method in combination with a virus-induced gene silencing (VIGS) strategy for rapid and reliable gene mapping, identification and functional verification. This method was applied to a multiple recessive marker line of upland cotton, Texas 582 (T582), and identified unique genomic positions harboring mutant loci, showing the reliability and efficacy of this method...

Inclusive STEM high schools (ISHSs) (where STEM is science, technology, engineering, and mathematics) admit students on the basis of interest rather than competitive examination. This study examines the central assumption behind these schools-that they provide students from subgroups underrepresented in STEM with experiences that equip them academically and attitudinally to enter and stay in the STEM pipeline. Hierarchical modeling was applied to data from student surveys and state longitudinal data records for 5113 students graduating from 39 ISHSs and 22 comprehensive high schools in North Carolina and Texas...

BACKGROUND: In an effort to reduce surgical site infection (SSI) rates, a large number of infection control practices (ICPs), including operating room attire policies, have been recommended. However, few have proven benefits and many are costly, time-consuming, and detrimental to provider morale. The goal of this multi-institution study was to determine which ICPs are associated with lower postoperative SSI rates. STUDY DESIGN: Twenty American College of Surgeons NSQIP and Texas Alliance for Surgical Quality-affiliated hospitals completed this Quality Improvement Assessment Board-approved study...

BACKGROUND: Almost all studies of post-acute care (PAC) focus on older persons, frequently those suffering from chronic health problems. Some research is available on PAC for the pediatric population in general. However, very few studies focus on PAC services for children with special health care needs (SHCN). OBJECTIVE: To investigate factors affecting the provision of PAC to children with SHCN. METHODS: Pooled cross-sectional data from Texas Department of State Health Services hospital discharge database from 2011-2014 were analyzed...

Cytauxzoon felis is a tick-borne hemoparasite that causes cytauxzoonosis in domestic cats in the United States. Historically, feline cytauxzoonosis was reported to be nearly always fatal. However, increasing evidence of cats surviving acute infection and/or harboring a chronic, subclinical infection has suggested the existence of different C. felis strains that may vary in pathogenicity. In this study, the intraspecific variation of the C. felis first and second ribosomal RNA internal transcribed spacer (ITS1, ITS2) regions was assessed for any clinical outcome or geographic associations...

The protozoan parasite Trypanosoma cruzi causes Chagas disease, uses kissing bugs as a vector, and is maintained in nature by a variety of wildlife reservoirs. Many natural cases of Chagas disease have been reported in NHP at facilities across the southern United States, where infected vectors and wildlife occur. Infection of NHP with T. cruzi can diminish their value as research models and lead to health problems and death. Identifying the modes of transmission and role of wildlife reservoirs in these facilities is therefore critical to guide interventions to reduce transmission...

INTRODUCTION: Accurate data on the number of births attended by certified nurse-midwives and certified midwives (CNMs/CMs) are required to establish the public health benefits attributed to the midwifery model of care and the role of CNMs/CMs in the US health care system. However, the number of CNM/CM-attended births may be underreported in birth certificate data. The purpose of this project was to estimate the number of births CNM practices attended in Texas hospitals in 2014 and to describe Texas CNMs' knowledge about their hospitals' policies on naming CNMs as birth attendants...

Among social insects, colony-level variation is likely to be widespread and have significant ecological consequences. Very few studies, however, have documented how genetic factors relate to behavior at the colony level. Differences in expression of the foraging gene have been associated with differences in foraging and activity of a wide variety of organisms. We quantified expression of the red imported fire ant foraging gene (sifor) in workers from 21 colonies collected across the natural range of Texas fire ant populations, but maintained under standardized, environmentally controlled conditions...

Short-term exposure to fine particulate matter (PM2.5) has been associated with increased risks of cardiovascular diseases (CVDs), but whether such associations are supportive of a causal relationship is unclear, and few studies have employed formal causal analysis methods to address this. We employed nonparametric methods to examine the associations between daily concentrations of PM2.5 and hospital admissions (HAs) for CVD among adults aged 75 years and older in Texas, USA. We first quantified the associations in partial dependence plots generated using the random forest approach...
