Recent Diarrhea Is Associated With Elevated Salivary Igg Responses To Cryptosporidium In Residents Of An Eastern Massachusetts Community, A. I. Egorov, L. M. Montuori Trimble, L. Ascolillo, H. D. Ward, Deborah A. Levy, R. D. Morris, E. N. Naumova, J. K. Griffiths

Journal Articles: Epidemiology

BACKGROUND: Serological data suggest that Cryptosporidium infections are common but underreported. The invasiveness of blood sampling limits the application of serology in epidemiological surveillance. We pilot-tested a non-invasive salivary anti-Cryptosporidium antibody assay in a community survey involving children and adults.

MATERIALS AND METHODS: Families with children were recruited in a Massachusetts community in July; symptoms data were collected at 3 monthly follow-up mail surveys. One saliva sample per person (n = 349) was collected via mail, with the last survey in October. Samples were analyzed for IgG and IgA responses to a recombinant C. hominis gp15 sporozoite protein using a …

Yates, Jørgen Vestbo, The Evaluation Of Copd Longitudinally To Identify Predictive Surrogate Endpoints (Eclipse) Investigators

Journal Articles: Pulmonary & Critical Care Med

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is a complex condition with pulmonary and extra-pulmonary manifestations. This study describes the heterogeneity of COPD in a large and well characterised and controlled COPD cohort (ECLIPSE).

METHODS: We studied 2164 clinically stable COPD patients, 337 smokers with normal lung function and 245 never smokers. In these individuals, we measured clinical parameters, nutritional status, spirometry, exercise tolerance, and amount of emphysema by computed tomography.

RESULTS: COPD patients were slightly older than controls and had more pack years of smoking than smokers with normal lung function. Co-morbidities were more prevalent in COPD patients than in …

Hereditary 1,25-Dihydroxyvitamin D-Resistant Rickets With Alopecia Resulting From A Novel Missense Mutation In The Dna-Binding Domain Of The Vitamin D Receptor., Peter J. Malloy, Jining Wang, Tarak Srivastava, David Feldman

Manuscripts, Articles, Book Chapters and Other Papers

The rare genetic recessive disease, hereditary vitamin D resistant rickets (HVDRR), is caused by mutations in the vitamin D receptor (VDR) that result in resistance to the active hormone 1,25-dihydroxyvitamin D(3) (1,25(OH)(2)D(3) or calcitriol). In this study, we examined the VDR from a young boy with clinical features of HVDRR including severe rickets, hypocalcemia, hypophosphatemia and partial alopecia. The pattern of alopecia was very unusual with areas of total baldness, adjacent to normal hair and regions of scant hair. The child failed to improve on oral calcium and vitamin D therapy but his abnormal chemistries and his bone X-rays normalized …

Fagerstrom Test For Nicotine Dependence Vs Heavy Smoking Index In A General Population Survey, M. Pérez-Ríos, M. I. Santiago-Pérez, B. Alonso, A. Malvar, X. Hervada, Jose De Leon

Psychiatry Faculty Publications

BACKGROUND: The Fagerström Test for Nicotine Dependence (FTND) is used for assessing nicotine dependence. A shorter test derived from the FTND used for the general population is the Heavy Smoking Index (HSI) (six questions vs. two). The objective of this study is to compare the validity of the HSI versus the FTND.

METHODS: A survey of tobacco use in the general population was carried out in the northern Spanish region of Galicia using both the FTND and the HSI to study a representative sample of 1655 daily smokers. The HSI was compared with the FTND, considered the gold standard. Measures …

Chylomicrons Promote Intestinal Absorption And Systemic Dissemination Of Dietary Antigen (Ovalbumin) In Mice, Yuehui Wang, Sarbani Ghoshal, Martin Ward, Willem De Villiers, Jerold Woodward, Erik Eckhardt

Internal Medicine Faculty Publications

BACKGROUND: A small fraction of dietary protein survives enzymatic degradation and is absorbed in potentially antigenic form. This can trigger inflammatory responses in patients with celiac disease or food allergies, but typically induces systemic immunological tolerance (oral tolerance). At present it is not clear how dietary antigens are absorbed. Most food staples, including those with common antigens such as peanuts, eggs, and milk, contain long-chain triglycerides (LCT), which stimulate mesenteric lymph flux and postprandial transport of chylomicrons through mesenteric lymph nodes (MLN) and blood. Most dietary antigens, like ovalbumin (OVA), are emulsifiers, predicting affinity for chylomicrons. We hypothesized that chylomicron …

Identifying Blood Biomarkers And Physiological Processes That Distinguish Humans With Superior Performance Under Psychological Stress., Amanda M. Cooksey, Nausheen Momen, Russell Stocker, Shane C. Burgess

CVM Publications

BACKGROUND: Attrition of students from aviation training is a serious financial and operational concern for the U.S. Navy. Each late stage navy aviator training failure costs the taxpayer over $1,000,000 and ultimately results in decreased operational readiness of the fleet. Currently, potential aviators are selected based on the Aviation Selection Test Battery (ASTB), which is a series of multiple-choice tests that evaluate basic and aviation-related knowledge and ability. However, the ASTB does not evaluate a person's response to stress. This is important because operating sophisticated aircraft demands exceptional performance and causes high psychological stress. Some people are more resistant to …

Documentation Of Body Mass Index And Control Of Associated Risk Factors In A Large Primary Care Network, Stephanie A. Rose, Alexander Turchin, Richard W. Grant, James B. Meigs

Internal Medicine Faculty Publications

BACKGROUND: Body mass index (BMI) will be a reportable health measure in the United States (US) through implementation of Healthcare Effectiveness Data and Information Set (HEDIS) guidelines. We evaluated current documentation of BMI, and documentation and control of associated risk factors by BMI category, based on electronic health records from a 12-clinic primary care network.

METHODS: We conducted a cross-sectional analysis of 79,947 active network patients greater than 18 years of age seen between 7/05 - 12/06. We defined BMI category as normal weight (NW, 18-24.9 kg/m²), overweight (OW, 25-29.9), and obese (OB, ≥ 30). We measured documentation …

Faculty Publications

Food insecurity is a risk factor for both HIV transmission and worse HIV clinical outcomes. We examined the prevalence of and factors associated with food insecurity among homeless and marginally housed HIV-infected individuals in San Francisco recruited from the Research on Access to Care in the Homeless Cohort. We used multiple logistic regression to determine socio-demographic and behavioral factors associated with food insecurity, which was measured using the Household Food Insecurity Access Scale. Among 250 participants, over half (53.6%) were food insecure. Higher odds of food insecurity was associated with being white, low CD4 counts, recent crack use, lack of …

Monitoring, Identification, And Intervention For Metabolic Disorders In Veterans With Psychotic Disorders, Michael Swtye

Yale Medicine Thesis Digital Library

In light of growing evidence that certain antipsychotics may cause potentially life-threatening metabolic side-effects, the purpose of this study was to determine how regularly mental health clinicians (MHCs) currently monitor and manage metabolic abnormalities in overweight and obese patients with psychotic disorders. We hypothesized that MHCs monitor, identify and intervene for metabolic abnormalities in their patients at significantly lower rates than primary care physicians (PCCs), and that such rates may jeopardize patient health. We performed a one-year cross-sectional medical record review of primary care and mental health routine outpatient visit notes from the West Haven Campus of the Veteran Affairs …

A Truncation Mutation In Tbc1d4 In A Family With Acanthosis Nigricans And Postprandial Hyperinsulinemia, Satya Dash, Hiroyuki Sano, Justin J. Rochford, Robert K. Semple

Dartmouth Scholarship

Tre-2, BUB2, CDC16, 1 domain family member 4 (TBC1D4) (AS160) is a Rab-GTPase activating protein implicated in insulin-stimulated glucose transporter 4 (GLUT4) translocation in adipocytes and myotubes. To determine whether loss-of-function mutations in TBC1D4 might impair GLUT4 translocation and cause insulin resistance in humans, we screened the coding regions of this gene in 156 severely insulin-resistant patients. A female presenting at age 11 years with acanthosis nigricans and extreme postprandial hyperinsulinemia was heterozygous for a premature stop mutation (R363X) in TBC1D4. After demonstrating reduced expression of wild-type TBC1D4 protein and expression of the truncated protein in lymphocytes from the proband, …

Laparoscopic Treatment Of Pancreatic Pseudocysts In Children., Suzanne M. Yoder, Steven Rothenberg, Kuojen Tsao, Mark L. Wulkan, Todd A. Ponsky, Shawn D. St Peter, Daniel J. Ostlie, Timothy D. Kane

Manuscripts, Articles, Book Chapters and Other Papers

BACKGROUND: Pancreatic pseudocysts are problematic sequelae of pancreatitis or pancreatic trauma causing persistent abdominal pain, nausea, and gastric outlet obstruction. Due to the low volume of disease in children, there is scant information in the literature on the operative management of pseudocysts with minimally invasive techniques. We conducted a multi-institutional review to illustrate several technical variations utilized in achieving laparoscopic cystgastrostomy in the pediatric population.

METHODS: A retrospective review was conducted of all patients who underwent laparoscopic cystgastrostomy in five institutions. Patient data, operative techniques, and postoperative course were analyzed.

RESULTS: There were 13 patients with a mean age of …

Faculty, Staff and Student Publications

OBJECTIVE: Chronic obstructive pulmonary disease (COPD) is the fourth leading cause of death in the United States but is often undertreated. COPD often overlaps with other conditions such as hypertension and osteoporosis, which are less morbid but may be treated more aggressively. We evaluated the prevalence of these comorbid conditions and compared testing, patient knowledge, and management in a national sample of patients with COPD.

METHODS: A survey was administered by telephone in 2006 to 1003 patients with COPD to evaluate the prevalence of comorbid conditions, diagnostic testing, knowledge, and management using standardized instruments. The completion rate was 87%.

RESULTS: …

Successional Change In Phosphorus Stoichiometry Explains The Inverse Relationship Between Herbivory And Lupin Density On Mount St. Helens, Jennifer L. Apple, Michael Wink, Shannon E. Wills, John G. Bishop

Biology

Background: The average nitrogen-to-phosphorus ratio (N:P) of insect herbivores is less than that of leaves, suggesting that P may mediate plant-insect interactions more often than appreciated. We investigated whether succession-related heterogeneity in N and P stoichiometry influences herbivore performance on N-fixing lupin (Lupinus lepidus) colonizing primary successional volcanic surfaces, where the abundances of several specialist lepidopteran herbivores are inversely related to lupin density and are known to alter lupin colonization dynamics. We examined larval performance in response to leaf nutritional characteristics using gelechiid and pyralid leaf-tiers, and a noctuid leaf-cutter. Methodology/Principal Findings: We conducted four studies. First, growth of larvae …

Rationale And Design Of A Trial Of Angiotensin-Converting Enzyme Inhibition In Infants With Single Ventricle., Daphne T. Hsu, Seema Mital, Chitra Ravishankar, Renee Margossian, Jennifer S. Li, Lynn A. Sleeper, Richard V. Williams, Jami C. Levine, Brian W. Mccrindle, Andrew M. Atz, Darlene Servedio, Lynn Mahony, Pediatric Heart Network Investigators, Girish S. Shirali

Manuscripts, Articles, Book Chapters and Other Papers

BACKGROUND: Angiotensin converting enzyme (ACE) inhibitors are known to improve clinical outcome and ventricular function in adults with heart failure. Infants with single-ventricle physiology show abnormalities in ventricular function as well as poor growth. The ability of an ACE inhibitor to preserve ventricular function and improve growth in these infants is unknown.

METHODS: The Pediatric Heart Network designed a randomized, double-blind trial to compare outcomes in infants with single-ventricle physiology receiving enalapril or placebo. Neonates < or =45 days old were eligible. The primary outcome is weight-for-age Z-score at 14 months of age. Secondary outcomes include other measures of somatic growth, laboratory and functional measures of heart failure, developmental indices, measures of ventricular size and function, and the relationship of the renin-angiotensin-aldosterone system genotype to the response to enalapril. The incidence and spectrum of adverse events will also be compared between treatment groups.

RESULTS: A total of 1,245 neonates were screened and 533 (43%) were eligible. The consent rate was 43%; 230 subjects were enrolled. Parental reluctance to …

Objectively Measured Physical Activity And Its Association With Adiponectin And Other Novel Metabolic Markers: A Longitudinal Study In Children (Earlybird 38)., Bs Metcalf, An Jeffery, J Hosking, Ld Voss, N Sattar, Tj Wilkin

Peninsula Medical School

OBJECTIVE: Recent evidence suggests that, in children, traditional markers of metabolic disturbance are related only weakly to physical activity. We therefore sought to establish the corresponding relationships with newer metabolic markers. RESEARCH DESIGN AND METHODS: This was a nonintervention longitudinal study of 213 healthy children recruited from 54 schools in Plymouth, U.K. MTI accelerometers were used to make objective 7-day recordings of physical activity at ages 5 +/- 0.3 (mean +/- SD), 6, 7, and 8 years. Overall physical activity was taken as the average of the four annual time points. The metabolic markers at 8 years were adiponectin, leptin, …

Gender Specific Differences In The Pros And Cons Of Smoking Among Current Smokers In Eastern Kentucky: Implications For Future Smoking Cessation Interventions, Dana A. Hazen, David M. Mannino, Richard Clayton

Preventive Medicine and Environmental Health Faculty Publications

This study investigated gender differences in the perceived “pros” and “cons” of smoking using the constructs of decisional balance (DB) and stage of change from the Transtheoretical Model. The population distribution for stage of change among a population-based, cross-sectional survey of 155 current smokers over 40 years was: precontemplation (22.6%), contemplation (41.9%), preparation (35.5%). Results of stepwise regression models indicated significant gender differences in DB were in the preparation stage of change; scores on the DB measure increased 3.94 points (95% CI: 1.94, 5.93) for male smokers. Interventions targeting the “pros” and “cons” of smoking may need to be gender …

Intracerebral Hemorrhage For The Palliative Care Provider: What You Need To Know., B Brent Simmons, Susan M Parks

Department of Family & Community Medicine Faculty Papers

Intracerebral hemorrhage (ICH) makes up 10%-30% of all strokes. Palliative care providers are often asked to get involved with ICH cases to aid with development of short-term and long-term goals. Prognosis can be calculated using the ICH score (based on Glasgow Coma Score score, ICH volume, presence of intraventricular hemorrhage, age, and location of origin) or the Essen score (based on age, NIH Stroke Scale [NIHSS], and level of consciousness). Do-not-resuscitate (DNR) status is important to discuss with families. Expert consensus states DNR is appropriate if the patient has two of the following: severe stroke, life-threatening brain damage, or significant …

Increased Myocardial Susceptibility To Repetitive Ischemia With High-Fat–Diet-Induced Obesity, Geeta D Thakker, Nikolaos G Frangogiannis, Pawel T Zymek, Saumya Sharma, Joe L Raya, Philip M Barger, Heinrich Taegtmeyer, Mark L Entman, Christie M Ballantyne

Faculty, Staff and Student Publications

Obesity and diabetes are frequently associated with cardiovascular disease. When a normal heart is subjected to brief/sublethal repetitive ischemia and reperfusion (I/R), adaptive responses are activated to preserve cardiac structure and function. These responses include but are not limited to alterations in cardiac metabolism, reduced calcium responsiveness, and induction of antioxidant enzymes. In a model of ischemic cardiomyopathy inducible by brief repetitive I/R, we hypothesized that dysregulation of these adaptive responses in diet-induced obese (DIO) mice would contribute to enhanced myocardial injury. DIO C57BL/6J mice were subjected to 15 min of daily repetitive I/R while under short-acting anesthesia, a protocol …

Predictors Of Emesis And Time To Goal Intake After Pyloromyotomy: Analysis From A Prospective Trial., Shawn D. St Peter, Kuojen Tsao, Susan W. Sharp, G W. Holcomb Iii, Daniel J. Ostlie

Manuscripts, Articles, Book Chapters and Other Papers

Background: Emesis after pyloromyotomy for pyloric stenosis is a common clinical phenomenon and the limiting factor in time to goal feeds. The amount of emesis that can be expected after myotomy is unknown. No data have been published that equip caregivers with the ability to understand which patients are more likely to have emesis and take longer to advance to goal feeds after pyloromyotomy. Therefore, we performed analysis of prospective data obtained from a randomized trial to determine if outcome can be predicted from preoperative or intraoperative variables.

Methods: The dataset was prospectively collected from a randomized trial comparing open …
