Lighting Schedules for Arizona Backyard Laying Flocks
No full textMaintaining steady egg production in backyard flocks requires understanding how changes in daylight length influence a hen’s natural laying cycle. It’s a common misconception that cold temperatures in the wintertime lead to decreased egg production. In fact, light exposure, or photoperiod, stimulates egg production through the pineal gland and the decreased daylight length in the winter is responsible for drops in egg production. This article explores effective lighting strategies to optimize egg production, ensure consistency, and meet the needs of hens at different life stages

Hospital Discharge Patterns and Outcomes Among Patients Hospitalized for Nonfatal Opioid Overdose in Arizona, 2016-2024
No full textIntroduction: Nonfatal opioid overdoses remain a significant public health issue. However, post-hospital discharge pathways and how they differ based on patient factors and co-occurring mental health conditions are still not well understood in Arizona. This dissertation focuses on three objectives: (1) identify predictors of discharge disposition after overdose hospitalization over time, (2) measure how discharge disposition influences hospital resource use (length of stay [LOS], total charges), and (3) explore the relationships between specific mental health categories and discharge outcomes among adults hospitalized for nonfatal opioid overdose from 2016–2024.Methods: A retrospective analysis was conducted using statewide discharge data from the Arizona Department of Health Services. Adults (≥18 years) with ICD-10 overdose codes T40.0X–T40.6X were included; emergency department discharges, ages 0-17, deaths, and law-enforcement discharges were excluded. The final number of observations included was 58,448. Discharge outcomes were routine, discontinued care, psychiatric hospital, health care facility, or home health. Multivariable logistic models estimated adjusted odds for each discharge type and mental illness. Multiple linear models evaluated log-transformed total charges, and LOS models assessed associations for stays >0 days, with all three studies adjusting for sociodemographic, clinical, and hospitalization factors. Analyses used SAS 9.4. Results: From 2016 to 2024, routine discharge was most common (51.5%), followed by health care facility (23.6%), home health (16.4%), discontinued care (4.6%), and psychiatric hospital (3.8%). The average length of stay (LOS) was 6.4 days (median 4.0); the average total charges were 54,880). After adjusting for covariates, discharges due to discontinued care increased during periods 2 and 3, while discharges to psychiatric hospitals, health care facilities, and home health remained consistent over time. Compared with routine discharge, transfer to a health care facility, home health, or psychiatric hospital was linked to significantly higher charges and longer LOS, whereas discontinued care was associated with lower charges and shorter LOS. After adjusting for covariates, the variation of mental illness was shown across discharge outcomes. Discussion: Across three studies, differences were identified in hospital and clinical variables related to nonfatal opioid overdoses. These findings highlight opportunities to enhance discharge planning, incorporate behavioral health services, and improve care transitions for patients with co-occurring mental illness and SUDs in Arizona.Release after 02/01/202
Oxytocin Receptor Genetic and Epigenetic Variation, Early Life Adversity, and Breastfeeding Outcomes: A Three-Manuscript Dissertation
No full textBackground: Suboptimal breastfeeding (BF) contributes to increased disease burden for both infants and lactating parents. Although social factors influencing formula supplementation and premature weaning are well documented, the physiological mechanisms underlying disrupted lactation remain less understood. Because BF is a biosocial process shaped by both biological and social forces, this dissertation applies a biosocial framework to examine how oxytocin system function relates to BF outcomes within the context of maternal early life adversity. The purpose of this dissertation was to investigate associations between oxytocin receptor (OXTR) genetic and epigenetic variation and BF outcomes, and to evaluate how early adverse experiences may modify these relationships. Three cohesive manuscripts collectively address this objective. Methods: Manuscript 1 is a scoping review conducted using PRISMA guidelines to synthesize existing research on oxytocin and OXTR genetic and epigenetic variation in relation to postpartum outcomes, including maternal mental health, maternal behavior, and BF. Manuscripts 2 and 3 draw on secondary data from a randomized controlled trial led by PI Dr. Aleeca Bell (NIH R01NR018828), examining mother–infant synchrony among women with childhood adversity. Manuscript 2 uses a cross-sectional design to assess relationships between adverse childhood experiences, OXTR genetic and DNA methylation variations, and exclusive BF at 1 month postpartum through moderation models. Manuscript 3 employs longitudinal mixed-effects models to test whether BF exposure at 2 months postpartum predicts OXTR methylation, and whether these associations differ by genotype. Results: Across studies, this dissertation identified gene × environment interactions involving OXTR variations that influence maternal postpartum outcomes, with BF emerging as the least studied outcome in the literature. In the empirical analyses, higher adversity exposure combined with the GG genotype at rs53576 was associated with greater likelihood of exclusive BF at 1 month. Additionally, higher BF exposure at 2 months postpartum was associated with increasedmethylation among GG individuals but decreased methylation among A-carriers. These findings suggest differential susceptibility to social and biological exposures, highlighting that OXTR genotype may shape maternal physiological responsiveness during both early life and the perinatal period. Conclusions: Together, these three manuscripts demonstrate that OXTR genetic and epigenetic variation is associated with BF outcomes and may represent a mechanistic pathway linking early life adversity, lactation physiology, and maternal adaptation. This work underscores BF as a biosocial phenomenon and supports further investigation to identify individuals at increased risk for suboptimal lactation outcomes and to inform targeted, biologically informed interventions
Enhancing Neurocritical Care Nursing Competency: An Educational Intervention of FOUR Score
No full textBackground: Mechanical ventilation is critical for Neurocritical Care Unit (NCCU) patients. Weaning poses significant challenges due to unique neurological considerations in traumatic brain injury (TBI), stroke, and subarachnoid hemorrhage (SAH) (Battaglini et al., 2021). Variability in weaning practices stems from inconsistent knowledge and application of key assessments, notably the Full Outline of UnResponsiveness Score (FOUR Score) (Roquilly, 2013). Bedside nurses play a central role in neurological monitoring; their competency in these assessments is crucial for standardizing care and enhancing outcomes (Battaglini et al., 2021). Purpose: This quality improvement project evaluated an evidence-based educational intervention on the FOUR Score for new graduate NCCU nurses (<1 year experience). The primary objective was to increase nurses’ knowledge and confidence in neurological assessment, supporting future practice improvements and standardizing care delivery. Methods: This intervention employed an evidence-based educational video on the FOUR Score for new graduate nurses. All participants completed pre-intervention surveys assessing baseline knowledge and confidence. Following the educational video, post-intervention surveys were administered immediately. Quantitative analysis compared pre- and post-intervention results using appropriate statistical methods. Results: Twenty-one new graduate nurses participated. Knowledge scores improved significantly from pre-intervention (M=4.81, SD=1.54) to post-intervention (M=9.10, SD=1.09), representing an 89.2% improvement (mean increase 4.29 points, 95% CI: 3.76-4.81), t(20)=17.18, p<0.001, with very large effect size (Cohen’s d=3.21). Self improved substantially across all domains, with overall confidence increasing from median 2.0 to 4.0 (Wilcoxon signed-rank test, p<0.001, r=0.90). Conclusions: This brief, multimodal educational intervention significantly enhanced new graduate neurocritical care nurses’ knowledge and confidence in performing FOUR Score assessments. The very large effect sizes suggest that video-based education combined with point-of-care reference tools represent an effective, scalable strategy for building competency in complex neurological assessments among nurses new to specialty practice
