Information About the Gut Microbiome's Connection to Health and Disease can Impact Knowledge: Feasibility of an Education-Based Intervention in a General Internal Medicine Clinic.

The gut microbiome (gMicrobiome)-a dynamic ecosystem of microorganisms-is emerging as a correlate of healthy lifestyle. Patients may not be aware of this. General Internal Medicine patients completed surveys evaluating gMicrobiome knowledge, lifestyle knowledge, dietary intake, physical activity, sleep, and stress.

Velocity changes in femoral vessel ultrasound with Doppler in Porcine hemorrhagic shock.

Objective: Physician-directed point-of-care ultrasound (PoCUS) is routinely used to identify the etiology of shock and guide therapy in the ICU. We performed a preclinical study to determine what changes are manifested in the femoral vessels during hemorrhagic shock on Duplex imaging and to generate a femoral vessel sonographic profile over the time course of shock.

Design & Setting: A preclinical study in swine was performed using a convenience sample of animals that were being used in a Trauma Surgery training lab.

Optic Nerve Sheath Point of Care Ultrasound: Image Acquisition.

The goal of this protocol is to develop a standardized method for acquiring images of the optic nerve sheath and measuring the optic nerve sheath diameter (ONSD). Diagnostic ultrasound of the ONSD to detect intracranial hypertension has traditionally faced many problems because of methodologic discrepancies. Due to inconsistencies in the measuring techniques, the potential for ONSD to become a non-invasive bedside monitoring tool for ICP has been hampered.

Evaluation of commercially available point-of-care ultrasound for automated optic nerve sheath measurement.

Background: Measurement of the optic nerve sheath diameter (ONSD) via ultrasonography has been proposed as a non-invasive metric of intracranial pressure that may be employed during in-field patient triage. However, first responders are not typically trained to conduct sonographic exams and/or do not have access to an expensive ultrasound device. Therefore, for successful deployment of ONSD measurement in-field, we believe that first responders must have access to low-cost, portable ultrasound and be assisted by artificial intelligence (AI) systems that can automatically interpret the optic nerve sheath ultrasound scan.

Effect of physical activity goals on aerobic physical activity: testing the mediating role of external and internal motivation.

Prior work has shown that primary care patients endorse one or more of the following PA goals, weight maintenance, overall benefits, stress reduction, weight loss, tone/body shape, overall well-being, cardiovascular fitness, and increased energy. Using self-determination theory as a guide, the present study tested whether these eight goals had indirect effects on likelihood of meeting aerobic PA guidelines through internal motivation, external motivation or both. Patients (N = 642; 60.

Population Selection and Sequencing of Wild Isolates Identifies a Region on Chromosome III Affecting Starvation Resistance.

To understand the genetic basis of complex traits, it is important to be able to efficiently phenotype many genetically distinct individuals. In the nematode , individuals have been isolated from diverse populations around the globe and whole-genome sequenced. As a result, hundreds of wild strains with known genome sequences can be used for genome-wide association studies (GWAS).

Physical activity goals among patients in a primary care setting.

One approach to increasing physical activity (PA) among adults is to develop interventions targeting PA goals that could be implemented in the primary care setting. However, there is little understanding of the types of goals that individuals bring with them into the primary care setting, which is a necessary first step in building interventions. There were three objectives of the study.

Collaboration Matters: Honey Bee Health as a Transdisciplinary Model for Understanding Real-World Complexity.

We develop a transdisciplinary deliberative model that moves beyond traditional scientific collaborations to include nonscientists in designing complexity-oriented research. We use the case of declining honey bee health as an exemplar of complex real-world problems requiring cross-disciplinary intervention. Honey bees are important pollinators of the fruits and vegetables we eat.

/FoxO promotes gluconeogenesis and trehalose synthesis during starvation to support survival.

/FoxO is required to survive starvation in , but how FoxO promotes starvation resistance is unclear. We show that /FoxO restructures carbohydrate metabolism by driving carbon flux through the glyoxylate shunt and gluconeogenesis and into synthesis of trehalose, a disaccharide of glucose. Trehalose is a well-known stress protectant, capable of preserving membrane organization and protein structure during abiotic stress.

dbl-1/TGF-β and daf-12/NHR Signaling Mediate Cell-Nonautonomous Effects of daf-16/FOXO on Starvation-Induced Developmental Arrest.

Nutrient availability has profound influence on development. In the nematode C. elegans, nutrient availability governs post-embryonic development.

Burden of Iron Deficiency Anemia in a Bariatric Surgery Population in the United States.

Background: Obesity is a serious condition affecting more than 35% of adults in the United States. In obese individuals for whom other weight control methods have been ineffective, bariatric surgery is a safe and effective method of weight control. An estimated 150,000 to 160,000 bariatric surgeries are performed in the United States yearly.

The Value of Pathological Examination of the Foreskin Following Circumcision.

Introduction: We determined the clinical impact and value of routine histopathological examination of the foreskin following circumcision.

Methods: We performed a retrospective study of 225 consecutive adult circumcisions. Indications for circumcision were categorized as benign or malignant based on preoperative clinical evaluation.

Treatment preferences among problem drinkers in primary care.

Objective: Alcohol misuse is common among primary care patients, yet many do not receive treatment because doctors believe problem drinkers are "in denial," or are unwilling to change their drinking habits. The real problem, however, may be that patients are being offered treatment modalities that do not meet their needs. This study was designed to measure the acceptability of various treatment options among drinkers who were currently not receiving treatment.

3D phenotyping and quantitative trait locus mapping identify core regions of the rice genome controlling root architecture.

Identification of genes that control root system architecture in crop plants requires innovations that enable high-throughput and accurate measurements of root system architecture through time. We demonstrate the ability of a semiautomated 3D in vivo imaging and digital phenotyping pipeline to interrogate the quantitative genetic basis of root system growth in a rice biparental mapping population, Bala × Azucena. We phenotyped >1,400 3D root models and >57,000 2D images for a suite of 25 traits that quantified the distribution, shape, extent of exploration, and the intrinsic size of root networks at days 12, 14, and 16 of growth in a gellan gum medium.

WormSizer: high-throughput analysis of nematode size and shape.

The fundamental phenotypes of growth rate, size and morphology are the result of complex interactions between genotype and environment. We developed a high-throughput software application, WormSizer, which computes size and shape of nematodes from brightfield images. Existing methods for estimating volume either coarsely model the nematode as a cylinder or assume the worm shape or opacity is invariant.

A microfluidic device and computational platform for high-throughput live imaging of gene expression.

To fully describe gene expression dynamics requires the ability to quantitatively capture expression in individual cells over time. Automated systems for acquiring and analyzing real-time images are needed to obtain unbiased data across many samples and conditions. We developed a microfluidics device, the RootArray, in which 64 Arabidopsis thaliana seedlings can be grown and their roots imaged by confocal microscopy over several days without manual intervention.

GiA Roots: software for the high throughput analysis of plant root system architecture.

Background: Characterizing root system architecture (RSA) is essential to understanding the development and function of vascular plants. Identifying RSA-associated genes also represents an underexplored opportunity for crop improvement. Software tools are needed to accelerate the pace at which quantitative traits of RSA are estimated from images of root networks.
