Center for Oral Health Research Faculty Publications

We evaluated the relationship between glucose abnormalities and periodontitis in overweight/obese individuals. Eight hundred and seventy (870) diabetes-free participants aged 40–65 years completed the three-year follow-up in the San Juan Overweight Adults Longitudinal Study. The ADA thresholds for fasting and 2-h post-load glucose and HbA1c were used to define prediabetes. The NHANES methods were used to assess periodontitis. Multivariable linear regression was used to evaluate the relationship between baseline glucose metabolism measures and periodontitis at follow-up, adjusting for potential confounders. There was no association between impaired glucose measures and mean pocket depth (PD), mean clinical attachment loss (CAL), or mean …

Prophylactic endoscopy is routine in adults with portal hypertension (PHTN), but there is limited data in pediatrics. We sought to describe our experience with prophylactic endoscopy in pediatric PHTN. This is a retrospective study of 87 children who began surveillance endoscopy prior to gastrointestinal bleeding (primary prophylaxis) and 52 who began after an episode of bleeding (secondary prophylaxis) from 01/01/1994 to 07/01/2019. Patients who underwent primary prophylaxis had a lower mean number of endoscopies (3.897 vs 6.269, p = 0.001). The primary prophylaxis group was less likely to require a portosystemic shunt (6% vs 15%, p < 0.001) with no difference in immediate complications (1% vs 2%, p = 0.173) or 2-week complications (1% vs 2%, p = 0.097). No deaths were related to variceal bleeding or endoscopy. Kaplan-Meier Survival Curve suggests improved transplant and shunt free survival in the primary prophylaxis group (log-rank p < 0.001). Primary and secondary endoscopic prophylaxis should be considered safe for the prevention of variceal hemorrhage in pediatric portal hypertension. There are differences in outcomes in primary and secondary prophylaxis, but unclear if this is due to patient characteristics versus treatment strategy. Further study is needed to compare safety and efficacy to watchful waiting.

Background: Low birth weight (LBW) is a common outcome of preterm birth, which increases the risk of an infant's morbidity and mortality. Approximately 20 million infants are born with LBW globally per year. Since a significant number of births in Pakistan take place at home, it is important to focus on the use of kangaroo mother care (KMC), the practice of skin-to-skin contact, in communities to prevent neonatal mortality and morbidity.
Objective: We employed a formative research approach to understand the context of communities and facilities with regard to neonatal care and KMC practice. The broader aims were to inform …

BACKGROUND: Obesity exacerbates age-related effects on body composition and physical and metabolic function. Which exercise mode is most effective in mitigating these deleterious changes in dieting older adults with obesity is unknown.

METHODS: In a randomized controlled trial, we performed a head-to-head comparison of aerobic (AEX), resistance (REX), or combination (COMB) exercise during matched ~10% weight loss in 160 obese older adults. Prespecified analyses compared 6-month changes in intermuscular adipose tissue (IMAT) and visceral adipose tissue (VAT) assessed using MRI, insulin sensitivity index (ISI) by oral glucose tolerance test, physical function using Modified Physical Performance Test (PPT), VO2peak, gait speed, …


Digestibility Estimates Based On A Grass Growth Model Are Distributed Via Internet To Finnish Farmers, Marketta Rinne, J. Nousiainen, I. Mattila, H. Nikander, P. Huhtanen Jan 2022

Digestibility Estimates Based On A Grass Growth Model Are Distributed Via Internet To Finnish Farmers, Marketta Rinne, J. Nousiainen, I. Mattila, H. Nikander, P. Huhtanen

IGC Proceedings (1977-2023)

Optimising the harvesting time of grass in primary growth is difficult under Finnish climatic conditions, because the digestibility of grass decreases on average by 0.5 percentage units daily. We constructed a model based on cumulative temperature and geographical location which estimates the digestibility of grass. This model is used to produce estimates utilising real time weather information. The estimates are presented as a map, which is revised daily. Farmers have free access to the maps via Internet.

Reducing Tillage Affects Long-Term Yields But Not Grain Quality Of Maize, Soybeans, Oats, And Wheat Produced In Three Contrasting Farming Systems, Kirsten Ann Pearsons, Emmanuel Chiwo Omondi, Brad J. Heins, Gladis Zinati, Andrew Smith, Yichao Rui

Agricultural and Environmental Sciences Faculty Research

Reducing tillage has been widely promoted to reduce soil erosion, maintain soil health, and sustain long-term food production. The effects of reducing tillage on crop nutritional quality in organic and conventional systems, however, has not been widely explored. One possible driver of crop nutritional quality might be the changing soil nitrogen (N) availability associated with reduced tillage in various management systems. To test how reducing tillage affects crop nutritional quality under contrasting conventional and organic farming systems with varied N inputs, we measured nutritional quality (protein, fat, starch, ash, net energy, total digestible nutrients, and concentrations of Ca, K, Mg, …

Do Empowered Women Receive Better Quality Antenatal Care In Pakistan? An Analysis Of Demographic And Health Survey Data, Muhammad Asim, Waqas Hameed, Sarah Saleem Jan 2022

Do Empowered Women Receive Better Quality Antenatal Care In Pakistan? An Analysis Of Demographic And Health Survey Data, Muhammad Asim, Waqas Hameed, Sarah Saleem

Community Health Sciences

Introduction: Quality antenatal care is a window of opportunity for improving maternal and neonatal outcomes. Numerous studies have shown a positive effect of women empowerment on improved coverage of maternal and reproductive health services, including antenatal care (ANC). However, there is scarce evidence on the association between women's empowerment and improved ANC services both in terms of coverage and quality. Addressing this gap, this paper examines the relationship between multi-dimensional measures of women empowerment on utilization of quality ANC (service coverage and consultation) in Pakistan.
Methods: We used Pakistan Demographic and Health Survey 2017-18 (PDHS) data which comprises of 6,602 …

Place Is Power: Investing In Communities As A Systemic Leverage Point To Reduce Breast Cancer Disparities By Race, Matthew Jay Lyons, Senaida Fernandez Poole, Ross C Brownson, Rodney Lyn

2020-Current year OA Pubs

Racial disparities in breast cancer present a vexing and complex challenge for public health. A diverse array of factors contributes to disparities in breast cancer incidence and outcomes, and, thus far, efforts to improve racial equity have yielded mixed results. Systems theory offers a model that is well-suited to addressing complex issues. In particular, the concept of a systemic leverage point offers a clue that may assist researchers, policymakers, and interventionists in formulating innovative and comprehensive approaches to eliminating racial disparities in breast cancer. Naming systemic racism as a fundamental cause of disparities, we use systems theory to identify residential …

How Humboldt County Native Populations Reacted And Rebounded From Covid-19, Collin Rocha, Amada Lang, Russell Attebery

Humboldt in the Time of COVID - Digital Archive

COVID had an immeasurable affect on businesses and life as we know it. That is no surprise, however, studies about COVID have focused far too long on the long-term economic and cultural impact that this pandemic has wrought upon the world. The human impact is far greater, and in the bubble of Humboldt country, the local population has felt that impact to a great degree, no more than the local native populations in and around Humboldt County, like the Karuk of Happy Camp, CA.

I spoke to tribal chairman Buster Attebery, in order to discover how experiences of the Karuk …

Comparison Of Percutaneous Vs Oral Infection Of Hamsters With The Hookworm Ancylostoma Ceylanicum: Parasite Development, Pathology And Primary Immune Response, Richard D. Bungiro, Lisa M. Harrison, Blaise Dondji, Michael Cappello Jan 2022

Comparison Of Percutaneous Vs Oral Infection Of Hamsters With The Hookworm Ancylostoma Ceylanicum: Parasite Development, Pathology And Primary Immune Response, Richard D. Bungiro, Lisa M. Harrison, Blaise Dondji, Michael Cappello

Biology Faculty Scholarship

Background

Hundreds of millions of people in poor countries continue to suffer from disease caused by bloodfeeding hookworms. While mice and rats are not reliably permissive hosts for any human hookworm species, adult Golden Syrian hamsters are fully permissive for the human and animal pathogen Ancylostoma ceylanicum. Similar to humans, hamsters may be infected with A. ceylanicum third-stage larvae orally or percutaneously. Oral infection typically leads to consistent worm yields in hamsters but may not accurately reflect the clinical and immunological manifestations of human infection resulting from skin penetration.

Methodology/Principal findings

In this study we compared host responses …


Re-Purposing Universities: The Path To Purpose, Victoria Hurth, Iain S. Stewart Jan 2022

Re-Purposing Universities: The Path To Purpose, Victoria Hurth, Iain S. Stewart

School of Geography, Earth and Environmental Sciences

As the extent of damage to environmental systems from our business-as-usual activity becomes ever more alarming, Universities as core social institutions are under pressure to help society lead the transition to a sustainable future. Their response to the issues, that they themselves have helped reveal, has, however, been widely criticised for being wholly inadequate. Universities can be observed to engage with sustainability issues inad-hocways, with the scale of attention and commitment dependant mainly on the level of pressure exerted by stakeholders that works to overcome aspects of inherent inertia. Sustainability initiatives can therefore be regarded mainly as bolt-ons. This mirrors …


Drought, Low Nitrogen Stress, And Ultraviolet-B Radiation Effects On Growth, Development, And Physiology Of Sweetpotato Cultivars During Early Season, Purushothaman Ramamoorthy, Raju Bheemanahalli, Stephen L. Meyers, Mark W. Shankle, Kambham Raja Reddy Jan 2022

Drought, Low Nitrogen Stress, And Ultraviolet-B Radiation Effects On Growth, Development, And Physiology Of Sweetpotato Cultivars During Early Season, Purushothaman Ramamoorthy, Raju Bheemanahalli, Stephen L. Meyers, Mark W. Shankle, Kambham Raja Reddy

Department of Horticulture & Landscape Architecture Faculty Publications

Drought, ultraviolet-B (UV-B), and nitrogen stress are significant constraints for sweetpotato productivity. Their impact on plant growth and development can be acute, resulting in low productivity. Identifying phenotypes that govern stress tolerance in sweetpotatoes is highly desirable to develop elite cultivars with better yield. Ten sweetpotato cultivars were grown under nonstress (100% replacement of evapotranspiration (ET)), drought-stress (50% replacement of ET), UV-B (10 kJ), and low-nitrogen (20% LN) conditions. Various shoot and root morphological, physiological, and gas-exchange traits were measured at the early stage of the crop growth to assess its performance and association with the storage root number. All …


Remote Sensing Application To Grassland Monitoring, Z. B. Nan Jan 2022

Remote Sensing Application To Grassland Monitoring, Z. B. Nan

IGC Proceedings (1977-2023)

Application of remote sensing to the management of grassland resources, the role this plays in developing sustainable grassland farming systems and opportunities for further development are outlined. Use of remote sensing technologies in grassland monitoring has a history of more than 30 years. Both fine- and coarse-grained remote sensing techniques are used to monitor and study grasslands. Fine-grained techniques are used to study landscape scale processes through the use of sensors providing spatial resolution of a few meters, whereas coarse-grained techniques are used to study catchment scale areas, and even entire biomes, using satellite-based sensors with a spatial resolution of …

Modelling Grassland Ecosystems, J. H. M. Thornley

IGC Proceedings (1977-2023)

In this contribution a view of the promise and difficulties of modelling grassland is given. This is largely centred around work with a grassland ecosystem simulator known as the Hurley Pasture Model.

A brief introduction sets forth possible reasons for building a large ecosystem model, and stresses the importance of modelling objectives. It is suggested that a model is de rigeur for any research programme which aims to take a firm grasp of the complex responses of grassland. Mechanistic models are required to provide the understanding needed for intelligent and flexible management of grassland, whatever the prevailing environmental or economic …
