Depression, Sensation Seeking, And Maternal Smoking As Predictors Of Adolescent Cigarette Smoking, Judy Van De Venne, Kay Bradford, Catherine A. Martin, Megan Cox, Hatim A. Omar

Family Sciences Faculty Publications

The purpose of this study was to examine maternal and adolescent depression, maternal and teen sensation seeking, and maternal smoking, and their associations with adolescent smoking. Data were collected from a sample of 47 male and 66 female adolescents (ages 11-18 years) and their mothers from three different health clinics. The findings indicated that maternal sensation seeking was linked indirectly with adolescent smoking through teen sensation seeking, both of which were significantly associated with teen smoking (β = 0.29, p < 0.001 and β = 0.32, p < 0.001, respectively). Teen depression was associated positively with teen smoking (β = 0.24, p < 0.01) when controlling for sensation seeking behaviors. Maternal smoking was also directly linked to adolescent smoking (β = 0.20, p < 0.05). These findings underscore a potentially important role of sensation seeking in the origins of adolescent smoking, and clarify pathways of influence with regard to maternal attitudes and behaviors in subsequent teenage nicotine use.

Medial Prefrontal Dissociations During Processing Of Trait Diagnostic And Nondiagnostic Person Information, Jason P. Mitchell, Jasmin Cloutier, Mahzarin R. Banaji, C Neil Macrae

Dartmouth Scholarship

Previous research has suggested that perceivers spontaneously extract trait-specific information from the behaviour of others. However, little is known about whether perceivers spontaneously engage in the same depth of social-cognitive processing for all person information or reserve such processing specifically for information that conveys diagnostic clues about another person's dispositions. Moreover, a question remains as to whether the processing of such nondiagnostic information can be affected by perceivers’ explicit goal to consider another's dispositions or not. To examine processing of diagnostic and nondiagnostic social information as a function of perceivers’ explicit social-cognitive goals, participants underwent functional magnetic resonance imaging (fMRI) …

Level I Fieldwork Today: A Study Of Contexts And Perceptions., Caryn Johnson, Kristie P. Koenig, Catherine Verrier Piersol, Susan E. Santalucia, Wendy Wachter-Schutz

Department of Occupational Therapy Faculty Papers

The last comprehensive examination of the Level I fieldwork experience was performed 15 years ago (Shalik, 1990) and addressed the different types of settings in which fieldwork occurred; amounts and types of supervision; structure and scheduling of the Level I experiences; and the effects of supervising Level I students on productivity. Although every occupational therapy and occupational therapy assistant student encounters a number of Level I fieldwork opportunities, little is available describing the process and contexts of the Level I fieldwork experience today. This study, which examines 1,002 student reports on Level I fieldwork experiences, finds that Level I fieldwork …

A Role For Cetp Taqib Polymorphism In Determining Susceptibility To Atrial Fibrillation: A Nested Case Control Study, Folkert W. Asselbergs, Jason H. Moore, Maarten P. Van Den Berg, Eric B. Rimm

Dartmouth Scholarship

Studies investigating the genetic and environmental characteristics of atrial fibrillation (AF) may provide new insights in the complex development of AF. We aimed to investigate the association between several environmental factors and loci of candidate genes, which might be related to the presence of AF. A nested case-control study within the PREVEND cohort was conducted. Standard 12 lead electrocardiograms were recorded and AF was defined according to Minnesota codes. For every case, an age and gender matched control was selected from the same population (n = 194). In addition to logistic regression analyses, the multifactor-dimensionality reduction (MDR) method and interaction …

Spontaneous Intracranial Arterial Dissection In The Young: Diagnosis By Ct Angiography, William C. Robertson, Curtis A. Given

Neurology Faculty Publications

BACKGROUND: Spontaneous carotid artery dissections have been rarely reported in children. Diagnosis has traditionally been confirmed by catheter arteriography. More recently diagnosis has been made by magnetic resonance imaging and magnetic resonance angiography; however the sensitivity of these techniques has yet to be determined. The authors are unaware of reports of carotid dissection confirmed by dynamic computed tomography (computerized tomographic arteriography) in the young.

CASE PRESENTATION: We recently evaluated a fourteen year-old male following the development of transient neurologic symptoms. There was no antecedent illness or trauma. Dynamic computed tomography revealed an intracranial dissection involving the supraclinoid segment of the …

Type 3 Deiodinase Is Critical For The Maturation And Function Of The Thyroid Axis, Arturo Hernandez, M. Elena Martinez, Steven Flering, Valerie Anne Galton, Donald St. German

Dartmouth Scholarship

Developmental exposure to appropriate levels of thyroid hormones (THs) in a timely manner is critical to normal development in vertebrates. Among the factors potentially affecting perinatal exposure of tissues to THs is type 3 deiodinase (D3). This enzyme degrades THs and is highly expressed in the pregnant uterus, placenta, and fetal and neonatal tissues. To determine the physiological role of D3, we have generated a mouse D3 knockout model (D3KO) by a targeted inactivating mutation of the Dio3 gene in mouse ES cells. Early in life, D3KO mice exhibit delayed 3,5,3′-triiodothyronine (T3) clearance, a markedly elevated serum T3 level, and …

Effects Of Lesions Of The Bed Nucleus Of The Stria Terminalis, Laterual Hypothalamus, Or Insular Cortex On Conditioned Taste Aversion And Conditioned Odor Aversion, Christopher T. Roman, Nino Nebieridze, Aristides Sastre, Steve Reilly

Scholarship and Professional Work – COPHS

The effects of permanent forebrain lesions on conditioned taste aversions (CTAs) and conditioned odor aversions (COAs) were examined in 3 experiments. In Experiment 1, lesions of the bed nucleus of the stria terminalis had no influence on CTA or COA acquisition. Although lesions of the lateral hypothalamus induced severe hypodipsia in Experiment 2, they did not prevent the acquisition of CTAs or COAs. Finally, in Experiment 3, lesions of the insular cortex retarded CTA acquisition but had no influence on COA acquisition. The implications of these findings are discussed with regard to the forebrain influence on parabrachial nucleus function during …

Suicide is a well-documented problem, ranking high in causes of death in the US and internationally. National and international programs have been designed to address the problem, as well as approaches targeting prison populations. Within these programs, knowledge of local risk factors is viewed as essential in identifying potential suicide completers. The current study expands existing knowledge of these risk factors in the Pennsylvania Department of Corrections by a) collecting descriptive data of completers and b) conducting a retrospective case control study. The descriptive data is utilized to create a profile of typical suicide completers in the PA DOC. The …

Cutaneous And Presumed Visceral Leishmaniasis In A Soldier Deployed To Afghanistan, James P. Woodrow, Joshua D. Hartzell, Jim Czarnik, David Brett-Major, Glenn Wortmann

Journal Articles: Epidemiology

Leishmaniasis has been frequently diagnosed in US military personnel returning from duty in Southwest Asia. The majority of cases have demonstrated cutaneous disease, although a few cases of visceral disease have been documented. We present the case of an immunocompetent, HIV-negative, US Army soldier who suffered both visceral and cutaneous manifestations of leishmaniasis after returning from deployment in Afghanistan. Overlap of cutaneous and visceral involvement is rare and has not been reported in our cohort. Latent Plasmodium vivax infection may have been an exacerbating cofactor. We discuss this case and present a review of the literature.

Atypical Features In Pleomorphic Adenoma--A Clinicopathologic Study And Implications For Management., M. Ethunandan, R. Witton, G. Hoffman, A. Spedding, P. A. Brennan

Peninsula Dental School

Pleomorphic adenoma is the most common salivary gland neoplasm and infrequently undergoes malignant transformation. Carcinoma ex pleomorphic adenoma is typically an infiltrative neoplasm with features of cellular pleomorphism, high mitotic activity, peri-neural and vascular invasion. More recently, sub-groups of pleomorphic adenoma have been described exhibiting vascular invasion and features of malignancy without evidence of extra-capsular extension. There is little information in the literature regarding how these different histological variants influence clinical presentation and outcome following primary treatment. Following a review of 100 consecutive pleomorphic adenomas removed from the major salivary glands, 4 cases with atypical histological features were found. Three …

Faculty, Staff and Students Publications

BACKGROUND: There is a continuous debate regarding the best bottle nipple to be used to enhance the bottle-feeding performance of a preterm infant. Aim: To verify that feeding performance can be improved by using the bottle nipple with the physical characteristics that enhance infants' sucking skills. METHODS: Ten "healthy" VLBW infants (941+/-273 g) were recruited. Feeding performance was monitored at two time periods, when taking 1-2 and 6-8 oral feedings/d. At each time and within 24 h, performance was monitored using three different bottle nipples offered in a randomized order. Rate of milk transfer (ml/min) was the primary outcome measure. …

Basal Endothelial Nitric Oxide Release Is Preserved In Overweight And Obese Adults, Christopher A Desouza, Gary P. Van Guilder, Jared J Greiner, Derek T Smith, Greta L Hoetzer, Brian L Stauffer

Health and Nutritional Sciences Faculty Publications

OBJECTIVE: Impaired basal nitric oxide release is associated with a number of cardiovascular disorders including hypertension, arterial spasm, and myocardial infarction. We determined whether basal endothelial nitric oxide release is reduced in otherwise healthy overweight and obese adult humans.
RESEARCH METHODS AND PROCEDURES: Seventy sedentary adults were studied: 32 normal weight (BMI/m(2)), 24 overweight (BMI > or = 25 < 30 kg/m(2)), and 14 obese (BMI > or = 30 kg/m(2)). Forearm blood flow (FBF) responses to intra-arterial infusions of N(g)-monomethyl-L-arginine (5 mg/min), a nitric oxide synthase inhibitor, were used as an index of basal nitric oxide release.
RESULTS: N(g)-monomethyl-L-arginine elicited significant reductions in FBF in the normal weight …

Stress Levels, Psychological Symptoms, And C-Reactive Protein Levels In Covid-19: A Cross-Sectional Study, Jian Zhang, Wei Li, Hideo Hoshi, Stephen L Mills, Stephen C Massey

Faculty, Staff and Student Publications

The correlation between cholinergic sensitivity and the level of stratification for ganglion cells was examined in the rabbit retina. As examples, we have used ON or OFF alpha ganglion cells and ON/OFF directionally selective (DS) ganglion cells. Nicotine, a cholinergic agonist, depolarized ON/OFF DS ganglion cells and greatly enhanced their firing rates but it had modest excitatory effects on ON or OFF alpha ganglion cells. As previously reported, we conclude that DS ganglion cells are the most sensitive to cholinergic drugs. Confocal imaging showed that ON/OFF DS ganglion cells ramify precisely at the level of the cholinergic amacrine cell dendrites, …

Manganese Distribution Across The Blood-Brain Barrier. Iv. Evidence For Brain Influx Through Store-Operated Calcium Channels, Janelle S. Crossgrove, Robert A. Yokel

Pharmaceutical Sciences Faculty Publications

Manganese (Mn) is a required co-factor for many ubiquitous enzymes; however, chronic Mn overexposure can cause manganism, a parkinsonian-like syndrome. Previous studies showed Mn influx into brain is carrier-mediated, though the putative carrier(s) were not established. Studies conducted with cultured bovine brain microvascular endothelial cells (bBMECs), which comprise the blood–brain barrier, revealed ⁵⁴Mn (II) uptake positively correlated with pH, was temperature-dependent, and was sodium- and energy-independent. Brain ⁵⁴Mn uptake correlated inversely with calcium (Ca) concentration, but ⁴⁵Ca uptake was unaltered by high Mn concentration. Lanthanum (La), a non-selective inhibitor of several Ca channel types, as well as …

Exhaled Breath Nitric Oxide: Is There A Baseline Difference Due To Ethnicity?, Sunita I. Patel M.D.

USF Tampa Graduate Theses and Dissertations

The air that humans exhale contains various chemical markers whose levels have been associated with various respiratory disorders. Therefore, measurement of these markers offers a potential method of examining airway disease status. Furthermore, exhaled breath offers the advantage of being easy to collect and non-invasive. Hence, these exhaled breath markers are potentially of significant clinical use in examining airways. Therefore, examination of exhaled breath has become the subject of intense study. Current research is targeting the development of methods and parameters for looking at these markers.

The goal of this cross-sectional pilot study was to consider the variability in the …

Information-Seeking Behaviors Of Practitioners In A Primary Care Practice-Based Research Network (Pbrn), James E. Andrews, Kevin A. Pearce, Carol Ireson, Margaret M. Love

School of Information Faculty Publications

OBJECTIVE: The aim of this study was to examine the information-seeking behaviors (e.g., information resource usage patterns, access to types of sources and to medical libraries, and use of particular information technologies) of members in a primary care practice-based research network (PBRN) to inform future efforts supporting primary care practitioners in their daily care of patients.

METHODS: Every primary care practitioner who was a member of the Kentucky Ambulatory Network-including family practitioners, general practitioners, nurse practitioners, and physician assistants-was surveyed. The cross-sectional survey included twenty-six questions to investigate the information-seeking behavior of primary care practitioners.

RESULTS: The response rate was …

Clinical Characteristics Of Individuals Using An Online Alcohol Evaluation Program., Daniel Z Lieberman

Psychiatry and Behavioral Sciences Faculty Publications

Access to treatment for substance abuse disorders is limited, and practical strategies are needed to expand opportunities for individuals to receive effective interventions. Automated or semi-automated treatments have shown promise in other disorders. Identifying the characteristics of patients who will be able to benefit from this unconventional approach will increase the likelihood of success. The current study examined 1,297 individuals using an online alcohol evaluation program. Subjects had high scores on the Alcohol Use Disorders Identification Test (AUDIT) and a substantial amount of ambivalence about the possible harm that their drinking caused, but they also had very low levels of …

Social Security And The African American Male (A Cash Transfer System), Eddie Davis

The Journal of Sociology & Social Welfare

All employed workers are required to contribute to the Social Security System; however,a disproportionatep ercentage of African American males never live long enough to collect any benefits from their contributions. On the other hand, the life-expectancy of white males is significantly longer than the life expectancy of African American males, and their collection of Social Security benefits tends to exceed their contributions to the system. The federal government keeps the Social Security system from becoming completely solvent by raiding it of any surplus funds it collects; thereby, preventing the Social Security Fund from developing interest income, and accumulating funds for …

Role For Akt3/Protein Kinase Bγ In Attainment Of Normal Brain Size, Rachel M. Easton, Han Cho, Kristin Roovers, Diana W. Shineman

Dartmouth Scholarship

Studies of Drosophila and mammals have revealed the importance of insulin signaling through phosphatidylinositol 3-kinase and the serine/threonine kinase Akt/protein kinase B for the regulation of cell, organ, and organismal growth. In mammals, three highly conserved proteins, Akt1, Akt2, and Akt3, comprise the Akt family, of which the first two are required for normal growth and metabolism, respectively. Here we address the function of Akt3. Like Akt1, Akt3 is not required for the maintenance of normal carbohydrate metabolism but is essential for the attainment of normal organ size. However, in contrast to Akt1^−/− mice, which display a …

The Meaning Of Computers To A Group Of Men Who Are Homeless., Kathleen Swenson Miller, Stacey Bunch-Harrison, Brett Brumbaugh, Rekha Sankaran Kutty, Kathleen Fitzgerald

Department of Occupational Therapy Faculty Papers

The purpose of this pilot study was to explore the experience with computers and the meaning of computers to a group of homeless men living in a long-term shelter. This descriptive exploratory study used semistructured interviews with seven men who had been given access to computers and had participated in individually tailored occupation based interventions through a Work Readiness Program. Three themes emerged from analyzing the interviews: access to computers, computers as a bridge to life-skill development, and changed self-perceptions as a result of connecting to technology. Because they lacked computer knowledge and feared failure, the majority of study participants …

A Pilot Randomized, Controlled Trial Of An In-Home Drinking Water Intervention Among Hiv + Persons, John M. Colford, Sona R. Saha, Timothy J. Wade, Catherine C. Wright, Mai Vu, Sandra Charles, Peter Jensen, Alan Hubbard, Deborah A. Levy, Joseph N. S. Eisenberg

Journal Articles: Epidemiology

Although immunocompromised persons may be at increased risk for gastrointestinal illnesses, no trials investigating drinking water treatment and gastrointestinal illness in such patients have been published. Earlier results from San Francisco suggested an association (OR 6.76) between tap water and cryptosporidiosis among HIV + persons. The authors conducted a randomized, triple-blinded intervention trial of home water treatment in San Francisco, California, from April 2000 to May 2001. Fifty HIV-positive patients were randomized to externally identical active (N = 24) or sham (N = 26) treatment devices. The active device contained a filter and UV light; the sham provided no treatment. …

Journal Articles: Epidemiology

Trials have provided conflicting estimates of the risk of gastrointestinal illness attributable to tap water. To estimate this risk in an Iowa community with a well-run water utility with microbiologically challenged source water, the authors of this 2000-2002 study randomly assigned blinded volunteers to use externally identical devices (active device: 227 households with 646 persons; sham device: 229 households with 650 persons) for 6 months (cycle A). Each group then switched to the opposite device for 6 months (cycle B). The active device contained a 1-microm absolute ceramic filter and used ultraviolet light. Episodes of "highly credible gastrointestinal illness," a …
