Master Gardener Satisfaction and Intent to Remain After Training via Remote Delivery

One year after using remote delivery via video web conferencing (VWC) in training, we surveyed Delaware master gardeners to assess the remote delivery trainees\u27 satisfaction and intent to remain as compared to those characteristics in volunteers who had had face-to-face training. Although the remote delivery trainees were satisfied overall, they were significantly less satisfied than those who had participated in face-to-face trainings. A more positive perception of the VWC experience was associated with master gardeners\u27 increased satisfaction, suggesting the importance of VWC quality. However, volunteers trained via VWC did not report more or less of an intention to remain with the organization

The Macroeconomic and Cultural Microcosms of Global Groceries

The aim of this thesis is to understand the global grocery market and to present a framework to assist sector players in developing go-to-market strategies as they expand abroad. In order to holistically study the cultural and economic implications of grocery stores across the world, we first selected six unique countries to focus our research: Singapore, Brazil, Chile, Australia, Germany, and the United States. In addition to having personally traveled to each of these countries, we chose to analyze these six very different markets in order to include a wide range of cultures and levels of economic development. We found that despite all nations having their own specific shopping habits and preferences, universal themes do exist in regards to trends and substantial factors in all grocery sectors around the world. With our findings, we created a framework made to aid multinational grocery store chains as well as product brands looking to enter foreign markets. The framework consists of seven universal determinants of retail and beverage success. Our framework is not a stand-alone solution and must be supplemented with thorough research about the potential market

Self-reported Adherence with the Use of a Device in a Clinical Trial as Validated by Electronic Monitors: the VIBES Study

Background: Adherences to treatments that require a behavioral action often rely on self-reported recall, yet it is vital to determine whether real time self reporting of adherence using a simple logbook accurately captures adherence. The purpose of this study was to determine whether real time self-reported adherence is an accurate measurement of device usage during a clinical trial by comparing it to electronic recording. Methods: Using data collected from older adult men and women (N=135, mean age 82.3 yrs; range 66 to 98 yrs) participating in a clinical trial evaluating a vibrating platform for the treatment of osteoporosis, daily adherence to platform treatment was monitored using both self-reported written logs and electronically recorded radio-frequency identification card usage, enabling a direct comparison of the two methods over one year. Agreement between methods was also evaluated after stratification by age, gender, time in study, and cognition status. Results: The two methods were in high agreement (overall intraclass correlation coefficient = 0.96). The agreement between the two methods did not differ between age groups, sex, time in study and cognitive function. Conclusions: Using a log book to report adherence to a daily intervention requiring a behavioral action in older adults is an accurate and simple approach to use in clinical trials, as evidenced by the high degree of concordance with an electronic monitor

“I Ran to Make a Point”: Predicting and Preventing Youth Runaway from Foster Care

Youth who run away from foster care experience danger to health and safety and increased risk of adverse child welfare outcomes. By applying a concurrent mixed-methods approach, this study aimed to develop a deeper understanding of runaway risk that used a person-centered lens and amplified youth voices. Collectively, this approach can inform service innovations to support youth placed in out-of-home care. Working with a foster care agency in Kansas, data sources comprised administrative data for youth ages 12 + in care, and interview data with 20 youth, 12 + in care. Quantitative analyses involved latent class analysis followed by multinomial logistic regression to investigate whether the population of youth in care was comprised of subpopulations with differential runaway risk and whether subpopulations would predict runaway behaviors. Qualitative analyses applied modified analytic inductive thematic analysis to explore critical life experiences that may act as risk or protective factors of running away from care. Results revealed four sub-populations which were characterized by their previous family and system experiences. Additionally, class membership, gender, number of siblings, and age were statistically significant predictors of runway behaviors. Youth interviews revealed five key themes on life experiences that mitigate or exacerbate youths’ runaway behaviors. Recommendations resulting from this study were provided in three key areas: (1) improving family visitation and maintaining youth connections with self-identified family and non-relative kin; (2) supporting service approaches for youth that honor and amplify their voices, choices, and family connections; and (3) improving placement quality and individualization of services

Pubertal lipid levels are significantly lower in youth with type 1 diabetes who experienced partial clinical remission

Importance: The physiologic changes in lipids during puberty in type 1 diabetes (T1D) is unclear as subjects in previous studies were not stratified by partial clinical remission (PCR) status. Aim: To determine the effect of PCR on lipid changes during puberty in youth with T1D. Subjects and Methods: A retrospective cross-sectional study of 194 subjects consisting of 71 controls of age 12.9±1.3y and 123 subjects with T1D stratified into remitters (n=44, age 13.0±0.8y) and non-remitters (n=79, age 11.2±0.6y). PCR was defined as insulin-dose adjusted HbA1c of ≤9. Pubertal status was determined by Tanner staging. Results: Among the pubertal cohort, low-density lipoprotein cholesterol concentration was significantly higher in the non-remitters compared to the remitters, 91.1±25.6mg/dL vs 77.2±25.8mg/dL, p=0.018; and the normal-weight controls, 91.1±25.6mg/dL vs 70.4±22.9 mg/dL, p=0.009; but was similar between the overweight/obese controls and non-remitters, 89.7±28.9mg/dL vs 91.1± 25.6mg/dL, p=0.81, and similarly between the normal-weight controls and remitters, 70.4±22.9mg/dL vs 77.2±25.8mg/dL, p=0.39. Total cholesterol was also significantly higher in the non-remitters compared to the remitters, 167.8±30.5 mg/dL vs 149.8±32.1mg/dL, p=0.012; and normal-weight controls, 167.8±30.5mg/dL vs 143.2±30.1mg/dL, p=0.011; but similar between the non-remitters and overweight/obese controls, p=0.098; and remitters and normal-weight controls, p=0.51. Non-HDL cholesterol was equally significantly higher in non-remitters compared to remitters, 111.3±30.1mg/dL vs 95.9±29.1mg/dL, p=0.028; and normal-weight controls, 111.3±30.1mg/dL vs 86.2± 32.2mg/dL, p=0.028; but similar between non-remitters and overweight/obese controls, p=0.48; and remitters versus normal-weight controls, p=0.39. Conclusions: Puberty-related reductions in LDL, TC, and non-HDL occur in remitters and normal-weight controls, but not in non-remitters and overweight/obese controls

Study design and rationale for a randomized controlled trial to assess effectiveness of stochastic vibrotactile mattress stimulation versus standard non-oscillating crib mattress for treating hospitalized opioid-exposed newborns

The incidence of Neonatal Abstinence Syndrome (NAS) continues to rise and there remains a critical need to develop non-pharmacological interventions for managing opioid withdrawal in newborns. Objective physiologic markers of opioid withdrawal in the newborn remain elusive. Optimal treatment strategies for improving short-term clinical outcomes and promoting healthy neurobehavioral development have yet to be defined. This dual-site randomized controlled trial (NCT02801331) is designed to evaluate the therapeutic efficacy of stochastic vibrotactile stimulation (SVS) for reducing withdrawal symptoms, pharmacological treatment, and length of hospitalization, and for improving developmental outcomes in opioid-exposed neonates. Hospitalized newborns (n = 230) receiving standard clinical care for prenatal opioid exposure will be randomly assigned within 48-hours of birth to a crib with either: 1) Intervention (SVS) mattress: specially-constructed SVS crib mattress that delivers gentle vibrations (30-60 Hz, ~12 mum RMS surface displacement) at 3-hr intervals; or 2) Control mattress (treatment as usual; TAU): non-oscillating hospital-crib mattress. Infants will be studied throughout their hospitalization and post discharge to 14-months of age. The study will compare clinical measures (i.e., withdrawal scores, cumulative dose and duration of medications, velocity of weight gain) and characteristic progression of physiologic activity (i.e., limb movement, cardio-respiratory, temperature, blood-oxygenation) throughout hospitalization between opioid-exposed infants who receive SVS and those who receive TAU. Developmental outcomes (i.e., physical, social, emotional and cognitive) within the first year of life will be evaluated between the two study groups. Findings from this randomized controlled trial will determine whether SVS reduces in-hospital severity of NAS, improves physiologic function, and promotes healthy development

Continuous glucose monitoring reduces pubertal hyperglycemia of type 1 diabetes

Background: Physiologic hyperglycemia of puberty is a major contributor to poor glycemic control in youth with type 1 diabetes (T1D). This study\u27s aim was to determine the effectiveness of continuous glucose monitoring (CGM) to improve glycemic control in pubertal youth with T1D compared to a non-CGM cohort after controlling for age, sex, BMI, duration, and insulin delivery methodology. The hypothesis is that consistent CGM use in puberty improves compliance with diabetes management, leading to increased percentage (%) time in range (TIR70-180 mg/dL) of glycemia, and lowering of HbA1c. Methods A longitudinal, retrospective, case-controlled study of 105 subjects consisting of 51 T1D controls (60.8% male) age 11.5 +/- 3.8 y; and 54 T1D subjects (48.1% male) age 11.1 +/- 5.0 y with confirmed CGM use for 12 months. Pubertal status was determined by Tanner staging. Results were adjusted for baseline HbA1c and diabetes duration. Results HbA1c was similar between the controls and the CGM group at baseline: 8.2 +/- 1.1% vs 8.3 +/- 1.2%, p=0.48 respectively; but was significantly lower in the CGM group 12 months later, 8.2 +/- 1.1% vs. 8.7 +/- 1.4%, p=0.035. Longitudinal change in HbA1c was similar in the prepubertal cohort between the control- and CGM groups: -0.17 +/- 0.98% vs. 0.38 +/- 1.5%, p=0.17. In contrast, HbA1c increased with advancing age and pubertal status in the pubertal controls but not in the pubertal CGM group: 0.55 +/- 1.4 vs -0.22 +/- 1.1%, p=0.020. Percent TIR was inversely related to HbA1c in the CGM group, r=-0.6, p=0.0004, for both prepubertal and pubertal subjects. Conclusions CGM use significantly improved glycemic control in pubertal youth with T1D compared to non-CGM users

Toward an Extended Definition of Major Depressive Disorder Symptomatology: Digital Assessment and Cross-validation Study.

BACKGROUND: Diagnosing major depressive disorder (MDD) is challenging, with diagnostic manuals failing to capture the wide range of clinical symptoms that are endorsed by individuals with this condition. OBJECTIVE: This study aims to provide evidence for an extended definition of MDD symptomatology. METHODS: Symptom data were collected via a digital assessment developed for a delta study. Random forest classification with nested cross-validation was used to distinguish between individuals with MDD and those with subthreshold symptomatology of the disorder using disorder-specific symptoms and transdiagnostic symptoms. The diagnostic performance of the Patient Health Questionnaire-9 was also examined. RESULTS: A depression-specific model demonstrated good predictive performance when distinguishing between individuals with MDD (n=64) and those with subthreshold depression (n=140) (area under the receiver operating characteristic curve=0.89; sensitivity=82.4%; specificity=81.3%; accuracy=81.6%). The inclusion of transdiagnostic symptoms of psychopathology, including symptoms of depression, generalized anxiety disorder, insomnia, emotional instability, and panic disorder, significantly improved the model performance (area under the receiver operating characteristic curve=0.95; sensitivity=86.5%; specificity=90.8%; accuracy=89.5%). The Patient Health Questionnaire-9 was excellent at identifying MDD but overdiagnosed the condition (sensitivity=92.2%; specificity=54.3%; accuracy=66.2%). CONCLUSIONS: Our findings are in line with the notion that current diagnostic practices may present an overly narrow conception of mental health. Furthermore, our study provides proof-of-concept support for the clinical utility of a digital assessment to inform clinical decision-making in the evaluation of MDD

The Delta Study - Prevalence and characteristics of mood disorders in 924 individuals with low mood: Results of the of the World Health Organization Composite International Diagnostic Interview (CIDI).

OBJECTIVES: The Delta Study was undertaken to improve the diagnosis of mood disorders in individuals presenting with low mood. The current study aimed to estimate the prevalence and explore the characteristics of mood disorders in participants of the Delta Study, and discuss their implications for clinical practice. METHODS: Individuals with low mood (Patients Health Questionnaire-9 score ≥5) and either no previous mood disorder diagnosis (baseline low mood group, n = 429), a recent (≤5 years) clinical diagnosis of MDD (baseline MDD group, n = 441) or a previous clinical diagnosis of BD (established BD group, n = 54), were recruited online. Self-reported demographic and clinical data were collected through an extensive online mental health questionnaire and mood disorder diagnoses were determined with the World Health Organization Composite International Diagnostic Interview (CIDI). RESULTS: The prevalence of BD and MDD in the baseline low mood group was 24% and 36%, respectively. The prevalence of BD among individuals with a recent diagnosis of MDD was 31%. Participants with BD in both baseline low mood and baseline MDD groups were characterized by a younger age at onset of the first low mood episode, more severe depressive symptoms and lower wellbeing, relative to the MDD or low mood groups. Approximately half the individuals with BD diagnosed as MDD (49%) had experienced (hypo)manic symptoms prior to being diagnosed with MDD. CONCLUSIONS: The current results confirm high under- and misdiagnosis rates of mood disorders in individuals presenting with low mood, potentially leading to worsening of symptoms and decreased well-being, and indicate the need for improved mental health triage in primary care

Diagnostic and Prognostic Significance of Complement in Patients with Alcohol-associated Hepatitis

BACKGROUND and AIMS: Given the lack of effective therapies and high mortality in acute alcohol-associated hepatitis (AH), it is important to develop rationally-designed biomarkers for effective disease management. Complement, a critical component of the innate immune system, contributes to uncontrolled inflammatory responses leading to liver injury, but is also involved in hepatic regeneration. Here we investigated if a panel of complement proteins and activation products would provide useful biomarkers for severity of AH and aid in predicting 90 days mortality. APPROACH and RESULTS: Plasma samples collected at time of diagnosis from 254 patients with moderate and severe AH recruited from four medical centers and 31 healthy individuals were used to quantify complement proteins by ELISA and Luminex arrays. Components of the classical and lectin pathways, including complement factors C2, C4b and C4d, as well as complement factor I (CFI) and C5, were reduced in AH patients compared to healthy individuals. In contrast, components of the alternative pathway, including complement factor Ba (CFBa) and factor D (CFD), were increased. Markers of complement activation were also differentially evident, with C5a increased and the soluble terminal complement complex (sC5b9) decreased in AH. Mannose binding lectin (MBL), C4b, CFI, C5 and sC5b9 were negatively correlated with model for end-stage liver disease (MELD) score, while CFBa and CFD were positively associated with disease severity. Lower CFI and sC5b9 were associated with increased 90-day mortality in AH. CONCLUSIONS: Taken together, these data indicate that AH is associated with a profound disruption of complement. Inclusion of complement, especially CFI and sC5b9, along with other laboratory indicators, could improve diagnostic and prognostic indications of disease severity and risk of mortality for AH patients
