Process Evaluation Of A Positive Youth Development Program In Hong Kong Based On Different Cohorts, Ben M. F. Law, Daniel T. L. Shek

Pediatrics Faculty Publications

There are only a few process evaluation studies on positive youth development programs, particularly in the Chinese context. This study aims to examine the quality of implementation of a positive youth development program (the Project P.A.T.H.S.: Positive Adolescent Training through Holistic Social Programmes) and investigate the relationships among program adherence, process factors, implementation quality, and perceived program success. Process evaluation of 97 classroom-based teaching units was conducted in 62 schools from 2005 to 2009. Findings based on different cohorts generally showed that there were high overall program adherence and implementation quality. Program adherence and implementation process were highly correlated with …

Dna Methylation Arrays As Surrogate Measures Of Cell Mixture Distribution, Eugene Houseman, William P. Accomando, Devin C. Koestler, Brock C. Christensen, Carmen J. Marsit

Dartmouth Scholarship

There has been a long-standing need in biomedical research for a method that quantifies the normally mixed composition of leukocytes beyond what is possible by simple histological or flow cytometric assessments. The latter is restricted by the labile nature of protein epitopes, requirements for cell processing, and timely cell analysis. In a diverse array of diseases and following numerous immune-toxic exposures, leukocyte composition will critically inform the underlying immuno-biology to most chronic medical conditions. Emerging research demonstrates that DNA methylation is responsible for cellular differentiation, and when measured in whole peripheral blood, serves to distinguish cancer cases from controls.

Eye Size At Birth In Prosimian Primates: Life History Correlates And Growth Patterns, Joshua R. Cummings, Magdalena N. Muchlinski, E. Christopher Kirk, Susan J. Rehorek, Valerie B. Deleon, Timothy D. Smith

Neuroscience Faculty Publications

BACKGROUND: Primates have large eyes relative to head size, which profoundly influence the ontogenetic emergence of facial form. However, growth of the primate eye is only understood in a narrow taxonomic perspective, with information biased toward anthropoids.

METHODOLOGY/PRINCIPAL FINDINGS: We measured eye and bony orbit size in perinatal prosimian primates (17 strepsirrhine taxa and Tarsius syrichta) to infer the extent of prenatal as compared to postnatal eye growth. In addition, multiple linear regression was used to detect relationships of relative eye and orbit diameter to life history variables. ANOVA was used to determine if eye size differed according to activity …

Novel Napi-Iic Mutations Causing Hhrh And Idiopathic Hypercalciuria In Several Unrelated Families: Long-Term Follow-Up In One Kindred., Y Yu, S R. Sanderson, M Reyes, A Sharma, N Dunbar, Tarak Srivastava, H Jüppner, C Bergwitz

Manuscripts, Articles, Book Chapters and Other Papers

Homozygous and compound heterozygous mutations in SLC34A3, the gene encoding the sodium-dependent co-transporter NaPi-IIc, cause hereditary hypophosphatemic rickets with hypercalciuria (HHRH), a disorder characterized by renal phosphate-wasting resulting in hypophosphatemia, elevated 1,25(OH)(2) vitamin D levels, hypercalciuria, rickets/osteomalacia, and frequently kidney stones or nephrocalcinosis. Similar albeit less severe biochemical changes are also observed in heterozygous carriers, which are furthermore indistinguishable from those encountered in idiopathic hypercalciuria (IH). We now searched for SLC34A3 mutations (exons and introns) in two previously not reported HHRH kindreds, which resulted in the identification of three novel mutations. The affected members of kindred A were compound heterozygous …

Relative Telomere Length: A Novel Non-Invasive Biomarker For The Risk Of Non-Cirrhotic Hepatocellular Carcinoma In Patients With Chronic Hepatitis B Infection., Xiaoying Fu, Shaogui Wan, Hie-Won Hann, Md, Ronald E Myers, Phd, Richard S Hann, Jennifer Au, Bicui Chen, Jinliang Xing, Hushan Yang

Division of Gastroenterology and Hepatology Faculty Papers

BACKGROUND AND AIMS: Telomere length has emerged as a promising risk predictor of various cancers including hepatocellular carcinoma (HCC). However, the majority of studies in this area measured telomere length in hepatocytes and one in lymphocytes with conflicting results. Moreover, no studies have been reported on using circulating DNA telomere length as a non-invasive HCC biomarker.

METHODS: We conducted a nested case-control study to determine the relative telomere length (RTL) in serum DNA from 140 hepatitis B virus (HBV)-related HCC cases and 280 frequency-matched cancer-free HBV controls.

RESULTS: Cases had a significantly longer RTL (median, 0.31; range, 0.02-2.31) than controls …

The Search For Health Information On The Internet: Perceptions Of Patient Medical Communication Competence During The Medical Appointment, Kelli K. Owen

Theses and Dissertations - UTB/UTPA

The Internet is an influential contrivance that has the potential to improve healthcare information dispersion, healthcare delivery and patient outcomes. Specifically, patient preparation prior to the medical appointment, such as seeking information about his/ her health situation on the Internet, has been linked to competent medical communication behaviors. As such, the Internet can potentially be used to introduce educational health materials that will help the patient prepare for the medical appointment. But, it is important to first determine Internet usage rates among the study population and assess patient and physician perceptions of the degree to which access to health information …

BACKGROUND: Survivors of the Norwood procedure may experience neurodevelopmental impairment. Clinical trials to improve outcomes have focused primarily on methods of vital organ support during cardiopulmonary bypass.

METHODS AND RESULTS: In the Single Ventricle Reconstruction trial of the Norwood procedure with modified Blalock-Taussig shunt versus right-ventricle-to-pulmonary-artery shunt, 14-month neurodevelopmental outcome was assessed by use of the Psychomotor Development Index (PDI) and Mental Development Index (MDI) of the Bayley Scales of Infant Development-II. We used multivariable regression to identify risk factors for adverse outcome. Among 373 transplant-free survivors, 321 (86%) returned at age 14.3 ± 1.1 (mean ± SD) months. Mean …

Uterine Epithelial Cells Specifically Induce Interferon-Stimulated Genes In Response To Polyinosinic-Polycytidylic Acid Independently Of Estradiol, Mickey V. Patel, Mimi Ghosh, John V. Fahey, Charles R. Wira

Dartmouth Scholarship

Interferon β (IFNβ) is an antiviral cytokine secreted in response to pathogenic exposure that creates a restrictive intracellular environment through the action of downstream interferon-stimulated genes (ISG). The objective of this study was to examine the expression of IFNβ and ISG in both human uterine epithelial cells (UEC) and the ECC-1 uterine epithelial cell line and determine if expression changes with TLR stimulation and hormone exposure. Stimulation of primary uterine epithelial cells and ECC-1 cells with the TLR3 agonist poly (I∶C) induced the mRNA expression of IFNβ, MxA, OAS2 and PKR. Other TLR agonists including imiquimod and CpG had no …

Evaluation Of A Positive Youth Development Program Based On The Repertory Grid Test, Daniel T. L. Shek

Pediatrics Faculty Publications

The repertory grid test, based on personal construct psychology, was used to evaluate the effectiveness of Project P.A.T.H.S. (Positive Adolescent Training through Holistic Social Programmes) in Hong Kong. One hundred and four program participants (n = 104) were randomly invited to complete a repertory grid based on personal construct theory in order to provide both quantitative and qualitative data for measuring self-identity changes after joining the program. Findings generally showed that the participants perceived that they understood themselves better and had stronger resilience after joining the program. Participants also saw themselves as closer to their ideal selves and other positive …

Encoding Of Sensory Prediction Errors In The Human Cerebellum., John Schlerf, Richard B Ivry, Jörn Diedrichsen

Brain and Mind Institute Researchers' Publications

A central tenet of motor neuroscience is that the cerebellum learns from sensory prediction errors. Surprisingly, neuroimaging studies have not revealed definitive signatures of error processing in the cerebellum. Furthermore, neurophysiologic studies suggest an asymmetry, such that the cerebellum may encode errors arising from unexpected sensory events, but not errors reflecting the omission of expected stimuli. We conducted an imaging study to compare the cerebellar response to these two types of errors. Participants made fast out-and-back reaching movements, aiming either for an object that delivered a force pulse if intersected or for a gap between two objects, either of which …

G9a Interacts With Snail And Is Critical For Snail-Mediated E-Cadherin Repression In Human Breast Cancer, Chenfang Dong, Yadi Wu, Jun Yao, Yifan Wang, Yinhua Yu, Piotr G. Rychahou, B. Mark Evers, Binhua P. Zhou

Molecular and Cellular Biochemistry Faculty Publications

Breast cancers are highly heterogeneous but can be grouped into subtypes based on several criteria, including level of expression of certain markers. Claudin-low breast cancer (CLBC) is associated with early metastasis and resistance to chemotherapy, while gene profiling indicates it is characterized by the expression of markers of epithelial-mesenchymal transition (EMT) - a phenotypic conversion linked with metastasis. Although the epigenetic program controlling the phenotypic and cellular plasticity of EMT remains unclear, one contributor may be methylation of the E-cadherin promoter, resulting in decreased E-cadherin expression, a hallmark of EMT. Indeed, reduced E-cadherin often occurs in CLBC and may contribute …

Rituximab Induces Sustained Reduction Of Pathogenic B Cells In Patients With Peripheral Nervous System Autoimmunity., Michael A Maurer, Goran Rakocevic, Carol S Leung, Isaak Quast, Martin Lukačišin, Norbert Goebels, Christian Münz, Hedda Wardemann, Marinos Dalakas, Jan D Lünemann

Department of Neurology Faculty Papers

The B cell-depleting IgG1 monoclonal antibody rituximab can persistently suppress disease progression in some patients with autoimmune diseases. However, the mechanism underlying these long-term beneficial effects has remained unclear. Here, we evaluated Ig gene usage in patients with anti-myelin-associated glycoprotein (anti-MAG) neuropathy, an autoimmune disease of the peripheral nervous system that is mediated by IgM autoantibodies binding to MAG antigen. Patients with anti-MAG neuropathy showed substantial clonal expansions of blood IgM memory B cells that recognized MAG antigen. The group of patients showing no clinical improvement after rituximab therapy were distinguished from clinical responders by a higher load of clonal …

Self-Harm And Suicidal Behaviors In Hong Kong Adolescents: Prevalence And Psychosocial Correlates, Daniel T. L. Shek, Lu Yu

Pediatrics Faculty Publications

The present paper examined the prevalence and psychosocial correlates of adolescent deliberate self-harm (DSH) and suicidal behavior in a representative sample of 3,328 secondary school students in Hong Kong. With reference to the previous year, 32.7% of the students reported at least one form of DSH, 13.7% of the respondents had suicide thoughts, 4.9% devised specific suicidal plans, and 4.7% had actually attempted suicide. Adolescent girls had significantly higher rates of DSH and suicidal behavior than did adolescent boys. Having remarried parents was related to an increased likelihood of DSH and suicide. While high levels of family functioning, overall positive …

Veterinary Science Faculty Publications

BACKGROUND: The objective of the study was to evaluate the gene expression of inflammatory cytokines (interleukin [IL]-1β, IL-6, IL-8, IL-10, tumor necrosis factor [TNF]-α, IL-1 receptor antagonist [ra] and serum amyloid A (SAA) in endometrial tissue and circulating leukocytes in response to uterine inoculation of 105 colony forming units (CFU) Escherichia coli in mares. Before inoculation, mares were classified as resistant or susceptible to persistent endometritis based on their uterine inflammatory response to infusion of 109 killed spermatozoa and histological assessment of the endometrial quality. Endometrial biopsies were obtained 3, 12, 24 and 72 hours (h) after bacterial inoculation and …

Oxidative Stress In Hpv-Driven Viral Carcinogenesis: Redox Proteomics Analysis Of Hpv-16 Dysplastic And Neoplastic Tissues, Federico De Marco, Elona Bucaj, Cesira Foppoli, Ada Fiorini, Carla Blarzino, Kozeta Filipi, Alessandra Giorgi, Maria Eugenia Schininà, Fabio Di Domenico, Raffaella Coccia, D. Allan Butterfield, Marzia Perluigi

Chemistry Faculty Publications

Genital infection by high risk Human Papillomavirus (HR-HPV), although recognized as the main etio-pathogenetic factor of cervical cancer, is not per se sufficient to induce tumour development. Oxidative stress (OS) represents an interesting and under-explored candidate as a promoting factor in HPV-initiated carcinogenesis. To gain insight into the role of OS in cervical cancer, HPV-16 positive tissues were collected from patients with invasive squamous cervical carcinoma, from patients with High Grade dysplastic HPV lesions and from patients with no clinical evidence of HPV lesions. After virological characterization, modulation of proteins involved in the redox status regulation was investigated. ERp57 and …

Department of Physical Therapy Faculty Papers

Abstract With the advent of new interventions targeted at both acute and chronic spinal cord injury (SCI), it is critical that techniques and protocols are developed that reliably evaluate changes in upper limb impairment/function. The Graded Redefined Assessment of Strength Sensibility and Prehension (GRASSP) protocol, which includes five subtests, is a quantitative clinical upper limb impairment measure designed for use in acute and chronic cervical SCI. The objectives of this study were to: (1) establish the inter-rater and test-retest reliability, and (2) establish the construct and concurrent validity with the International Standards of Neurological Classification of Spinal Cord Injury (ISNCSCI), …

Neuronal Encoding Of Subjective Value In Dorsal And Ventral Anterior Cingulate Cortex, Xinying Cai, Camillo Padoa-Schioppa

Open Access Publications

We examined the activity of individual cells in the primate anterior cingulate cortex during an economic choice task. In the experiments, monkeys chose between different juices offered in variables amounts and subjective values were inferred from the animals' choices. We analyzed neuronal firing rates in relation to a large number of behaviorally relevant variables. We report three main results. First, there were robust differences between the dorsal bank (ACCd) and the ventral bank (ACCv) of the cingulate sulcus. Specifically, neurons in ACCd but not in ACCv were modulated by the movement direction. Furthermore, neurons in ACCd were most active before …

The Effects Of Parentification, Attachment, Family-Of-Origin Dysfunction And Health On Depression: A Comparative Study Between Gender And The Ethnic Groups Of South Koreans And Caucasian Americans, Sunnie Giles

Theses and Dissertations

Parentification is a process where children or adolescents assume adult roles before they are emotionally or developmentally ready, which, in turn, disrupts the development of healthy, secure attachment in childhood. Using 1,001 men and women from South Korea and the United States with equal division between males and females and multiple group comparison technique in structural equation modeling, this paper examined the relationship between parentification during childhood and depression during adulthood. It explores the cross-sectional long-term effects of parentification into adulthood, using a retrospective survey technique. This study also confirmed previous research findings that attachment, physical health and family-of-origin dysfunction, …

Complexity Of Case Mix In A Regional Allergy Service., Edward R. Kaminski, Claire A. Bethune, Ray B. Jones

School of Nursing and Midwifery

BACKGROUND: Currently in the United Kingdom (UK), there is a mismatch between limited financial resources and the large proportion of patients with suspected allergies actually being referred to specialist allergy clinics. To better understand the case mix of patients being referred, we audited referrals to a regional allergy service over an 8 year period.The main source of data was consultant letters to General Practitioners (GP) summarising the diagnosis of patients, archived from January 2002 to September 2009. Letters were reviewed, extracting the clinic date, doctor seen, gender, date of birth, postcode, GP, and diagnoses. Diagnoses were classified into seven groups …

A Community-Integrated Home Based Depression Intervention For Older African Americans: Descripton Of The Beat The Blues Randomized Trial And Intervention Costs., Laura N Gitlin, Lynn Fields Harris, Megan Mccoy, Nancy L Chernett, Eric Jutkowitz, Laura T Pizzi

Center for Applied Research on Aging and Health Research Papers

ABSTRACT: BACKGROUND: Primary care is the principle setting for depression treatment; yet many older African Americans in the United States fail to report depressive symptoms or receive the recommended standard of care. Older African Americans are at high risk for depression due to elevated rates of chronic illness, disability and socioeconomic distress. There is an urgent need to develop and test new depression treatments that resonate with minority populations that are hard-to-reach and underserved and to evaluate their cost and cost-effectiveness. METHODS/DESIGN: Beat the Blues (BTB) is a single-blind parallel randomized trial to assess efficacy of a non-pharmacological intervention to …

A secondary aim of this study is to evaluate the mechanisms by which our HC intervention impacts on weight …

The Social Production Of Substance Abuse And Hiv/Hcv Risk: An Exploratory Study Of Opioid-Using Immigrants From The Former Soviet Union Living In New York City, Honoria Guarino, Sarah K. Moore, Lisa A. Marsch, Sal Florio

Dartmouth Scholarship

Several former Soviet countries have witnessed the rapid emergence of major epidemics of injection drug use (IDU) and associated HIV/HCV, suggesting that immigrants from the former Soviet Union (FSU) may be at heightened risk for similar problems. This exploratory study examines substance use patterns among the understudied population of opioid-using FSU immigrants in the U.S., as well as social contextual factors that may increase these immigrants' susceptibility to opioid abuse and HIV/HCV infection. In-depth interviews were conducted with 10 FSU immigrants living in New York City who initiated opioid use in adolescence or young adulthood, and with 6 drug treatment …
