Integrating Behavioral Health Into Family Medicine: Improving Access To Specialty Care For Medically Underserved Community Using A Collaborative Care Model, Christina M. Stephens Jan 2024

Integrating Behavioral Health Into Family Medicine: Improving Access To Specialty Care For Medically Underserved Community Using A Collaborative Care Model, Christina M. Stephens

DNP Scholarly Projects

Primary care, an extension of family medicine remains a key access point for patients entering the healthcare system. Accessing specialty psychiatric services can be limited in rural communities due to provider shortages and geographical constraints. Primary care providers can facilitate improved access to behavioral health services by introducing a collaborative approach to the traditional medical model. This quality improvement initiative adopted the collaborative care model originally produced by the University of Washington to treat common mental health conditions in the medical setting (2023). A team consisting of a primary care provider, behavioral health case manager and psychiatric consultant served nine …

Effects Of 0, 8, Or 16g/D Of Nicotinic Acid To Prepartum Jersey Cows: Effects On Glucose Concentration In Their Calves, Kaitlyn M. Zarrella Jan 2024

Effects Of 0, 8, Or 16g/D Of Nicotinic Acid To Prepartum Jersey Cows: Effects On Glucose Concentration In Their Calves, Kaitlyn M. Zarrella

Honors Theses and Capstones

The primary objective of this research project is to further investigate the optimization of colostrum production in multiparous Jersey cows, focusing on the influence of diet and seasonal factors. Previous findings by Dr. Stahl in 2023 at the University of New Hampshire Burley-Demeritt Organic Dairy Research Farm indicated that an intake of 23 g/d of nicotinic acid (Niacin; NA) might have been excessive for prepartum Jersey cows, potentially affecting colostrum yield and quality. While an enhancement in intestinal development was noted in calves receiving colostrum from cows supplemented with nicotinic acid, the dosage may have been too high to positively …


Thirty Years Of ‘Emergency’ Food Aid In The Us And Canada: Findings From Comparative Research To Inform Uk Efforts To Tackle Food Poverty And The Need For Foodbanks, Charlotte Spring Jan 2024

Thirty Years Of ‘Emergency’ Food Aid In The Us And Canada: Findings From Comparative Research To Inform Uk Efforts To Tackle Food Poverty And The Need For Foodbanks, Charlotte Spring

Geography and Environmental Studies Faculty Publications

Research observed how food providers in the United States and Canada have made changes during the decades of neoliberal policymaking that have seen foodbanking expand across North America and beyond. These changes, in part, reflect responses to critiques of foodbanking as an inadequate solution to food insecurity. Food charities have variously attempted to improve provision through healthier procurement, choice-based distribution models, diversified programming, and advocacy for policy solutions. Better foodbanking, however, does not negate the influence of corporate donors on food charities’ capacity to foster hunger-preventative change, such as the employment practices of those same donors. Meanwhile, grassroots organisers …

Survival Outcomes In T3 Laryngeal Cancer Based On Staging Features At Diagnosis, Vickie Jiaying Wang Jan 2024

Survival Outcomes In T3 Laryngeal Cancer Based On Staging Features At Diagnosis, Vickie Jiaying Wang

Yale Medicine Thesis Digital Library

Stage T3 laryngeal cancer is defined by the presence of vocal cord fixation and/or invasion into any of the following: pre-epiglottic space, paraglottic fat, post-cricoid space, or inner cortex of the thyroid cartilage. These cancers are usually treated with chemoradiation rather than upfront total laryngectomy. To our knowledge, no studies have directly compared differences in survival among the varied features within the T3 staging category. This study aims to determine how the presence of each of these staging features impacts overall and laryngectomy-free survival.Patients with clinically-diagnosed T3 laryngeal squamous cell carcinoma seen at our institution between 2010-2021 were retrospectively identified. …

Stability Of Child Appetitive Traits And Association With Diet Quality At 5 Years And 9–11 Years Old: Findings From The Rolo Longitudinal Birth Cohort Study, Anna Delahunt, Sarah Louise Killeen, Eileen C. O'Brien, Aisling A. Geraghty, Sharleen L. O'Reilly, Ciara M. Mcdonnell, Rosemary Cushion, John Mehegan, Fionnuala M. Mcauliffe

Articles

Background: We explored change in child appetitive traits from 5 to 9–11 years old and examined associations between appetitive traits at both timepoints and child diet quality. Methods: This is secondary analyses of the ROLO longitudinal birth cohort study, including mother-child dyads from the 5 and 9–11-year old follow-up. The Children's Eating Behaviour Questionnaire measured child appetitive traits, with 167 children having matched data for both timepoints. The Healthy Eating Index (HEI) measured diet quality. Linear mixed models and multiple linear regression were completed. Results: Mean (SD) score for ‘Emotional Overeating' (1.63 (0.51) vs. 1.99 (0.57), p = <0.001) and ‘Enjoyment of Food' (3.79 (0.72) vs. 3.98 (0.66), p = <0.001) increased from 5 to 9–11 years. Mean score for ‘Desire to Drink' (2.63 (0.94) vs. 2.45 (0.85), p = 0.01), ‘Satiety Responsiveness (3.07 (0.66) vs. 2.71 (0.66), p = <0.001), ‘Slowness Eating' (3.02 (0.77) vs. 2.64 (0.78), p = <0.001), and ‘Food Fussiness' (3.00 (1.04) vs. 2.81 (0.96), p = 0.001) decreased. At 5-years-old, ‘Food Responsiveness' and ‘Enjoyment of Food' were positively associated with HEI and ‘Desire to Drink', ‘Satiety Responsiveness' and ‘Food Fussiness' were negatively associated with HEI. At 9–11-years, ‘Enjoyment of Food' was positively and ‘Desire to Drink' and ‘Food ‘Fussiness' were negatively associated with HEI. Conclusions: Food approach appetitive traits increased over time, whereas food avoidant appetitive traits tended to decrease. At both time points ‘Food Fussiness' and ‘Desire to Drink” were inversely associated with HEI. Further research on how appetitive traits track over childhood and how this relates to dietary quality and weight is warranted.

Research Report: Radicchio Cultivar Performance In New Hampshire, Rebecca G. Sideman, Ella Lukacz, Lilly Hartman Jan 2024

Research Report: Radicchio Cultivar Performance In New Hampshire, Rebecca G. Sideman, Ella Lukacz, Lilly Hartman

Faculty Publications

Radicchio (Cichorium intybus var. latifolium) is grown widely throughout Europe, especially northern Italy. In addition to having interesting color and flavor profiles, they are rich in phenolics and other bioactive compounds. While increasingly popular as a niche vegetable in the region, there is little research-based information to guide growers. The New England growing climate is very different from that of major production regions, and it presents unique challenges. There is tremendous phenotypic variation among and within groups and cultivars. The availability of varieties to commercial growers in the U.S. has expanded greatly, but there remains a need for reliable …

The objectives of this study were to 1) formulate a novel energy bar containing significant macronutrients and calories per serving with favorable ratings from consumers; 2) analyze responses to a consumer preference survey and sensory evaluation of novel energy bars compared to a commercially available energy bar. For the first study, fourteen iterations of an energy bar were synthesized with differing protein sources (whey, soy, pea, hemp), and characteristic variations (nougat, chocolate truffle, peanut butter, double-date caramel). A shortbread base, date caramel, and chocolate coating were included in every bar. Sensory evaluations determined that the most liked variation overall was …


Cellular Level Changes Induced In Cancer Cells Due To Microgravity, Sai Deepika Reddy Yaram Jan 2024

Cellular Level Changes Induced In Cancer Cells Due To Microgravity, Sai Deepika Reddy Yaram

Graduate Theses, Dissertations, and Problem Reports (ETD)

The increase in human activity in space has revealed several kinds of physiological challenges brought on by the absence of Earth's gravitational pull. NASA observed that during spaceflight, astronauts experience a 1-1.5% monthly loss in the mineral density of weight-bearing bones, with rehabilitation efforts on Earth often proving ineffective. This issue extends to muscles, the neuro vestibular system, the cardiovascular system, and vision. Cancer has emerged as a significant cause of mortality among astronauts, with studies up to 2017 showing that 41.3% of natural cause deaths among U.S. astronauts were due to cancer, primarily due to space radiation exposure. Cancer …


Banning Plastic, Rachael E. Salcido Jan 2024

Banning Plastic, Rachael E. Salcido

Utah Law Review

The disgusting nature of plastic pollution has finally captured the attention of policymakers and driven legal change. Local, state, and national bans on various plastic consumer items coupled with voluntary industry switching creates momentum toward a full-scale end to unnecessary plastic products. Bans have the capacity to create an important tipping point. This Article extolls the effectiveness of consumer bans and explores the challenges to achieving this highest level of environmental control. Plastic is essentially pure petroleum.1 Its persistence and destructiveness in the environment presents unique reasons to eliminate its use altogether. Plastics should only be used for essential products …


Mapping The ‘Particlescape’: Diversity And Activity Of Microbial Communities Associated With Particles In The Marine Environment., Cordelia Roberts Jan 2024

Mapping The ‘Particlescape’: Diversity And Activity Of Microbial Communities Associated With Particles In The Marine Environment., Cordelia Roberts

School of Biological and Marine Sciences Theses

Particles are hotspots for marine microbial communities and impact ecosystem functioning, including the biological carbon pump. Although particle microbiomes differ across particle composition, type, size, source, and life history, this heterogeneity is often overlooked by using bulk-scale sampling approaches. In addition, knowledge of microbial eukaryotes in particle microbiomes is limited. I broadly set out to investigate how particle associated communities are structured at the macro and micro-scale which may have implications for wider food web interactions and biogeochemical cycling. In independent research chapters, I examined the diversity of bacteria (chapter 1) and activity of microbial eukaryotes associated with organic material …

The Thermal Performance And Tolerance Of Tropical Cleaner Shrimp (Lysmata Amboinensis), Sancha Conway Holroyd

School of Biological and Marine Sciences Theses

This thesis explores the theoretical and experimental applications of ecophysiological research for the management of aquatic organismal health within the ornamental trade. Ecophysiology investigates the interactions between an organism’s physiology and its environment, and offers a promising approach to improving the management of health outcomes for traded species. Chapter One presents a comprehensive and critical literature review that explores the potential of ecophysiology to redefine our understanding of health, by integrating ecophysiological perspectives into practice. Using Hatch’s (1962) theoretical framework as a foundation to define health, the review discusses the importance of understanding species-specific responses to key physio-chemical parameters for …


Using Ecosystem Services Mapping In Deep-Sea Marine Spatial Planning, Giulia La Bianca Jan 2024

Using Ecosystem Services Mapping In Deep-Sea Marine Spatial Planning, Giulia La Bianca

School of Biological and Marine Sciences Theses

Assessing and mapping ecosystem services (ES) has emerged as an important practice to support natural resource management and set conservation priorities. This is recognised as useful in enabling simultaneous attainment of socio-economic and ecological goals. Yet there exists a bias towards assessing ES in terrestrial and coastal systems. Deep-sea applications are particularly scant. Assessing ES provided by the deep sea is undermined by the lack of ecological data and scientific understanding of the links between ecosystem components and human well-being. Thus, novel tools are required to translate existing deep-sea ES knowledge into Marine Spatial Planning (MSP), while maintaining acceptable levels …

The research focuses on a particular context: a major transition in the participants’ lives: their return to education, while working full-time as chefs. Their experiences are considered unique since they, as a group, navigate between two worlds: industry and academia. Notably, a recent study in Ireland found that professionalism is an important career success factor for chefs. …


Synthetic Microbial Communities For Plastic Upcycling, Isabel B. A. Valencia Jan 2024

Synthetic Microbial Communities For Plastic Upcycling, Isabel B. A. Valencia

Dissertations, Master's Theses and Master's Reports

Plastic waste and human hunger pose major threats to the health and wellbeing of populations world-wide. Using microbial methods to upcycle polyethylene terephthalate (PET) plastic into value-added compounds such as single cell protein (SCP) for human consumption is a unique solution to both these issues. Two monomers of chemically deconstructed PET (DCPET), terephthalate (TPA) and ethylene glycol (EG), have been previously shown to be biodegradable by enriched microbial communities. Using this top-down knowledge to inform the reconstruction of a minimal microbial community constructed from isolated members of these communities is a novel way to efficiently process these monomers via a …

Divergent Response To Anthropogenic Change Within The Songbird Taxon: Insights From The Range Expansion Of The Northern Cardinal And Mitigation Mechanisms For Migratory Bird-Building Collisions, Jenna Brewer Jan 2024

Divergent Response To Anthropogenic Change Within The Songbird Taxon: Insights From The Range Expansion Of The Northern Cardinal And Mitigation Mechanisms For Migratory Bird-Building Collisions, Jenna Brewer

Dissertations, Master's Theses and Master's Reports

Anthropogenic activities have impacted ecosystems across the globe. However, wildlife species have exhibited heterogenous responses to these novel changes, with some species experiencing population growth, and others succumbing to population decline. I studied examples of both within the songbird taxon, focusing on drivers of range expansion in the Northern Cardinal and acoustic mitigation mechanisms for migratory bird-building collisions, a source of decline for many songbird species. I found that the Northern Cardinal’s range was primarily a function of climatic stress, which was supported by the modulation of the molt process across latitudes. Specifically, Northern Cardinals exhibited faster feather growth rates …

Biostatistics Faculty Publications

Recent examples for unplanned external events are the global COVID-19 pandemic, the war in Ukraine, or most recently Hurricane Ian in Puerto Rico. Disruptions due to unplanned external events can lead to violation of assumptions in clinical trials. In certain situations, randomization tests can provide nonparametric inference that is robust to violation of the assumptions usually made in clinical trials. The ICH E9 (R1) Addendum on estimands and sensitivity analyses provides a guideline for aligning the trial objectives with strategies to address disruptions in clinical trials. In this article, we embed randomization tests within the estimand framework to allow for …


A Systematic Review Of Creating An Ideal Adult Day Center For People With Dementia In Ghana (Sub-Saharan Africa), Christopher Lartei Aryee Jan 2024

A Systematic Review Of Creating An Ideal Adult Day Center For People With Dementia In Ghana (Sub-Saharan Africa), Christopher Lartei Aryee

Graduate Research Papers

Historically, the concept of adult day centres for people with dementia and other neurocognitive impairments has emanated from the West. Currently, in most western countries, such as the United States and the United Kingdom, these facilities have become an important part of the continuum of care for the elderly and disabled (Doherty et al., 2020). These adult daycare centers provide a planned environment for medical supervision, social activities, and recreational therapy on an individual basis. Most countries in Sub-Saharan Africa, however, like Ghana, have been slow in developing such facilities. Stigma associated with dementia and mental disorders, coupled with a …


Body Image In College Athletics, Tyrell Gordon Jan 2024

Body Image In College Athletics, Tyrell Gordon

Graduate Research Papers

Body image dissatisfaction of college athletes is a real problem and it is affecting female athletes at an alarming rate compared to their male counterparts. Body image is a multidimensional construct involving perceptions and attitudes of the body’s functional capabilities and physical appearance. Although women experience a greater level of body dissatisfaction than men, previous research shows that men are experiencing greater levels of negative body image than in the past. The dominant explanation for this trend is one of two things, the first of which is that women participate in more aesthetically pleasing sports such as soccer, gymnastics, volleyball, …

The Effects Of Sleep Quality On The Performance And Health Of Athletes, Andy Niese Jan 2024

The Effects Of Sleep Quality On The Performance And Health Of Athletes, Andy Niese

Graduate Research Papers

The quest for victorious supremacy within competitive athletics is a never-ending battle, a cutthroat process where the more successful athletes are willing to go to the extremes of physical training and nutritional modifications to gain any kind of edge over their opponents, many of whom are countering those efforts with the exact same type of self-fortifying tactics. Yet, the rudimentary human need for sleep is often an underestimated and forgotten weapon in enhancing and maximizing athletic performance. Furthermore, it would not be an exaggeration to categorize the basic existential tenant of sleep as the deal breaker for an athlete’s performance …


Contribution Of The Transcription Factor Red Nac To Low Nitrogen Phenotypes In Poplar, Shane Alexander Spence Jan 2024

Contribution Of The Transcription Factor Red Nac To Low Nitrogen Phenotypes In Poplar, Shane Alexander Spence

Dissertations, Master's Theses and Master's Reports

Greenhouse grafting and field trials were conducted to examine the contribution of the RED NAC transcription factor on low nitrogen phenotypes in hybrid poplar (P. tremula x P. alba). Reciprocal grafting trials showed both root and shoot expression contribute to phenotype under low nitrogen conditions, and shoot expression has a leading role in contribution to low-nitrogen phenotype. The impact of RED NAC expression level on auxin polar transport was investigated using a DR5::GUS auxin-responsive reporter gene line as rootstock for RED NAC modified scions. Pilot studies indicate the rate of auxin transport from apex to roots is slower through shoots …


The Role Of Neighborhood Effects In Maintaining The Hardwood-Hemlock Mosaic, Adam Z. Milenkowic Jan 2024

The Role Of Neighborhood Effects In Maintaining The Hardwood-Hemlock Mosaic, Adam Z. Milenkowic

Dissertations, Master's Theses and Master's Reports

Neighborhood effects are processes mediated by canopy trees that influence the ability of a species to replace itself following canopy mortality. Sugar maple (Acer saccharum Marsh.) and eastern hemlock (Tsuga canadensis (L.) Carr.) are the dominant trees in old-growth northern hardwood forests of Upper Michigan and have been observed to form monodominant patches in the region. Few studies have independently evaluated the demographic and ecological mechanisms that lead to the compositional stability of hemlock and sugar maple patch development. Tree demography data from eight long-term 0.5 ha old-growth plots in Upper Michigan indicate neighborhood effects are playing a …
