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.

Factor Structure Of A Multidimensional Gender Identity Scale In A Sample Of Chinese Elementary School Children, Lu Yu, Dong Xie, Daniel T. L. Shek

Pediatrics Faculty Publications

This study examined the factor structure of a scale based on the four-dimensional gender identity model (Egan and Perry, 2001) in 726 Chinese elementary school students. Exploratory factor analyses suggested a three-factor model, two of which corresponded to "Felt Pressure" and "Intergroup Bias" in the original model. The third factor "Gender Compatibility" appeared to be a combination of "Gender Typicality" and "Gender Contentment" in the original model. Follow-up confirmatory factor analysis (CFA) indicated that, relative to the initial four-factor structure, the three-factor model fits the current Chinese sample better. These results are discussed in light of cross-cultural similarities and differences …

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 …

Evaluation Of The Project P.A.T.H.S. Based On Students' Weekly Diaries: Findings From Eight Datasets, Daniel T. L. Shek, Rachel C. F. Sun

Pediatrics Faculty Publications

This paper aims to investigate the effectiveness of the Tier 1 Program of the Project P.A.T.H.S. (positive adolescent training through holistic social programmes) based on eight datasets collected between 2005 and 2009. A total of 1,138 students who participated in the program were randomly invited (from the whole grade or in some classes) to write a piece of journal in the form of a weekly diary in order to reveal their perceptions and feelings regarding the program and the perceived benefits of the program. Based on an integration of findings from different databases, results showed that the respondents generally (1) …

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 …

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 …

Journal Articles: Psychiatry

OBJECTIVE: This study tested whether positive response to short-term treatment for adolescent major depressive disorder (MDD) would have the secondary benefit of preventing subsequent alcohol use disorders (AUD) or substance use disorders (SUD).

METHOD: For 5 years, we followed 192 adolescents (56.2% female; 20.8% minority) who had participated in the Treatment for Adolescents with Depression Study (TADS; TADS Team, 2004) and who had no prior diagnoses of AUD or SUD. TADS initial treatments were cognitive behavior therapy (CBT), fluoxetine alone (FLX), the combination of CBT and FLX (COMB), or clinical management with pill placebo (PBO). We used both the original …

Inflammatory Responses To Induced Infectious Endometritis In Mares Resistant Or Susceptible To Persistent Endometritis, Mette Christoffersen, Elizabeth Woodward, Anders M. Bojesen, Stine Jacobsen, Morten R. Petersen, Mats H. T. Troedsson, Henrik Lehn-Jensen

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 …

Unfakeable Facial Configurations Affect Strategic Choices In Trust Games With Or Without Information About Past Behavior, Constantin Rezlescu, Brad Duchaine, Christopher Y. Olivola, Nick Chater

Dartmouth Scholarship

Background:

Many human interactions are built on trust, so widespread confidence in first impressions generally favors individuals with trustworthy-looking appearances. However, few studies have explicitly examined: 1) the contribution of unfakeable facial features to trust-based decisions, and 2) how these cues are integrated with information about past behavior.

Methodology/Principal Findings:

Using highly controlled stimuli and an improved experimental procedure, we show that unfakeable facial features associated with the appearance of trustworthiness attract higher investments in trust games. The facial trustworthiness premium is large for decisions based solely on faces, with trustworthy identities attracting 42% more money (Study 1), and remains …

Hyccin, The Molecule Mutated In The Leukodystrophy Hypomyelination And Congenital Cataract (Hcc), Is A Neuronal Protein., Elisabetta Gazzerro, Simona Baldassari, Caterina Giacomini, Veronica Musante, Floriana Fruscione, Veronica La Padula, Roberta Biancheri, Sonia Scarfì, Valeria Prada, Federica Sotgia, Ian D Duncan, Federico Zara, Hauke B Werner, Michael P Lisanti, Lucilla Nobbio, Anna Corradi, Carlo Minetti

Kimmel Cancer Center Faculty Papers

"Hypomyelination and Congenital Cataract", HCC (MIM #610532), is an autosomal recessive disorder characterized by congenital cataract and diffuse cerebral and peripheral hypomyelination. HCC is caused by deficiency of Hyccin, a protein whose biological role has not been clarified yet. Since the identification of the cell types expressing a protein of unknown function can contribute to define the physiological context in which the molecule is explicating its function, we analyzed the pattern of Hyccin expression in the central and peripheral nervous system (CNS and PNS). Using heterozygous mice expressing the b-galactosidase (LacZ) gene under control of the Hyccin gene regulatory elements, …

Developing An Online Learning Community For Mental Health Professionals And Service Users: A Discursive Analysis., Janet Smithson, Ray B. Jones, Emily Ashurst

School of Nursing and Midwifery

BACKGROUND: There is increasing interest in online collaborative learning tools in health education, to reduce costs, and to offer alternative communication opportunities. Patients and students often have extensive experience of using the Internet for health information and support, and many health organisations are increasingly trying out online tools, while many healthcare professionals are unused to, and have reservations about, online interaction. METHODS: We ran three week-long collaborative learning courses, in which 19 mental health professionals (MHPs) and 12 mental health service users (MHSUs) participated. Data were analysed using a discursive approach to consider the ways in which participants interacted, and …

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, …

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 …

Environmentally Realistic Exposure To The Herbicide Atrazine Alters Some Sexually Selected Traits In Male Guppies, Kausalya Shenoy

Biology Faculty Publications

Male mating signals, including ornaments and courtship displays, and other sexually selected traits, like male-male aggression, are largely controlled by sex hormones. Environmental pollutants, notably endocrine disrupting compounds, can interfere with the proper functioning of hormones, thereby impacting the expression of hormonally regulated traits. Atrazine, one of the most widely used herbicides, can alter sex hormone levels in exposed animals. I tested the effects of environmentally relevant atrazine exposures on mating signals and behaviors in male guppies, a sexually dimorphic freshwater fish. Prolonged atrazine exposure reduced the expression of two honest signals: the area of orange spots (ornaments) and the …

Protocol For A Randomized Controlled Trial Of A Specialized Health Coaching Intervention To Prevent Excessive Gestational Weight Gain And Postpartum Weight Retention In Women: The Hipp Study., Helen Skouteris, Marita Mccabe, Jeannette Milgrom, Bridie Kent, Lauren J. Bruce, Cathrine Mihalopoulos, Sharon J. Herring, Malcolm Barnett, Denise Patterson, Glyn Teale, Janette Gale

School of Nursing and Midwifery

BACKGROUND: Pregnancy is a time of significant physiological and physical change for women. In particular, it is a time at which many women are at risk of gaining excessive weight. We describe the rationale and methods of the Health in Pregnancy and Post-birth (HIPP) Study, a study which aims primarily to determine the effectiveness of a specialized health coaching (HC) intervention during pregnancy, compared to education alone, in preventing excessive gestational weight gain and postpartum weight retention 12 months post birth. A secondary aim of this study is to evaluate the mechanisms by which our HC intervention impacts on weight …

Electrophysiological Examination Of Embodiment In Vision And Action., Jeremy Goslin, Thomas Dixon, Martin H. Fischer, Angelo Cangelosi, Rob Ellis

School of Psychology

A wealth of behavioral data has shown that the visual properties of objects automatically potentiate motor actions linked with them, but how deeply are these affordances embedded in visual processing? In the study reported here, we used electrophysiological measures to examine the time course of affordance resulting from the leftward or rightward orientation of the handles of common objects. Participants were asked to categorize those objects using a left- or right-handed motor response. Lateralized readiness potentials showed rapid motor preparation in the hand congruent with the affordance provided by the object only 100 to 200 ms after stimulus presentation and …

Follicle-Stimulating Hormone Is Independently Associated With Lean Mass But Not Bmd In Younger Postmenopausal Women, Margaret L Gourlay, Bonny Specker, Chenxi Li, Catherine A. Hammett-Stabler, Jordan B. Renner, Janet E Rubin

Ethel Austin Martin Program Publications

PURPOSE: Increased follicle-stimulating hormone (FSH) has been associated with lower bone mineral density (BMD) in animal models and longitudinal studies of women, but a direct effect has not been demonstrated.
METHODS: We tested associations between FSH, non-bone body composition measures and BMD in 94 younger (aged 50 to 64 years) postmenopausal women without current use of hormone therapy, adjusting for sex hormone concentrations and clinical risk factors for osteoporosis. Lean mass, fat mass and areal BMD (aBMD) at the spine, femoral neck and total hip were measured using dual energy X-ray absorptiometry (DXA). Volumetric BMD (vBMD) was measured at the …

Examining Fatigue In Copd: Development, Validity And Reliability Of A Modified Version Of Facit-F Scale, Khaled Al-Shair, Hana Muellerova, Janelle Yorke, Stephen I. Rennard, Emiel F.M. Wouters, Nicola A. Hanania, Amir Sharafkhaneh, Jørgen Vestbo, Eclipse Investigators

Journal Articles: Pulmonary & Critical Care Med

INTRODUCTION: Fatigue is a disruptive symptom that inhibits normal functional performance of COPD patients in daily activities. The availability of a short, simple, reliable and valid scale would improve assessment of the characteristics and influence of fatigue in COPD.

METHODS: At baseline, 2107 COPD patients from the ECLIPSE cohort completed the Functional Assessment of Chronic Illness Therapy Fatigue (FACIT-F) scale. We used well-structured classic method, the principal components analysis (PCA) and Rasch analysis for structurally examining the 13-item FACIT-F.

RESULTS: Four items were less able to capture fatigue characteristics in COPD and were deleted. PCA was applied to the remaining …

Neural Network Diagnostic System For Dengue Patients Risk Classification, T. Faisal, M.N. Taib, Fatimah Ibrahim

Research Publications (2011 to 2015)

With the dramatic increase of the worldwide threat of dengue disease, it has been very crucial to correctly diagnose the dengue patients in order to decrease the disease severity. However, it has been a great challenge for the physicians to identify the level of risk in dengue patients due to overlapping of the medical classification criteria. Therefore, this study aims to construct a noninvasive diagnostic system to assist the physicians for classifying the risk in dengue patients. Systematic producers have been followed to develop the system. Firstly, the assessment of the significant predictors associated with the level of risk in …

James Marion Sims, M.D., Ll.D., Jonathan Tavares, B.S., Charles J. Yeo, Md, Pinckney J. Maxwell, Iv, Md

Department of Surgery Gibbon Society Historical Profiles

Few physicians have been as celebrated and loathed as James Marion Sims, M.D., LL.D. Dr. Sims’ modest early life and education never could have predicted that he would one day be called the ‘‘Father of American Gynecology.’’1, 2 Lauded by contemporaries and early historians as ‘‘one of the most original and gifted of American surgeons,’’ he performed the first successful operation to correct vesicovaginal fistulas (a condition that prior to 1852 was known as the ‘‘stumbling-block of gynecology’’).1 Today, the same work that earned Dr. Sims fame, fortune, and innumerable honors has been called into question, because of the unethical …

Trends In Hospital Admissions For Myocardial Infarcts For Women In Arizona, Florida And Maryland In 2000 To 2010, Rebecca Farmer Mcintyre

MUSC Theses and Dissertations

Coronary arterial disease is the leading cause of death and morbidity in developing countries. Acute myocardial infarction (AMI) has traditionally been considered a disease affecting mostly men, yet women are increasingly at risk due to obesity and diabetes. However, current trends in the AMI risk for women are not well understood. This study used archival data on hospital discharges from three states within the USA to examine the 10-year trend in presentations of patients to emergency rooms (ER) with a presenting diagnosis of chest pain and AMI, to document rate changes by gender over time. We observed a decreasing number …

Sexual Dimorphism In Periapical Inflammation And Bone Loss From Map Kinase Phosphatase-1 Deficient Mice, Justin Mcabee

MUSC Theses and Dissertations

Introduction: Mitogen Activating Protein (MAPK) kinase phosphatase-1 (MKP-1) has been shown to be a key negative regulator of the MAP kinase pathways of the innate immune system. The impact of MKP-1 in an endodontic model has yet to be studied. Thus, the purpose of this study was to determine the role of MKP-1 in a bacterial-driven model of pathological endodontic bone loss. Methods: Pulps were exposed in both lower 1st molars of 10-week old Dusp-1+1+IMKP-1 +1+ and Dusp-1-1-IMKP-1-1- mice and left open to the oral environment for either 3 or 8 weeks. At sacrifice, mandibles were harvested and scanned by …

The body composition of female collegiate athletes was measured using the Bod Pod® device. The sample consisted of 75 student athletes, aged 18 to 22 years old. Five sports at the university level were represented, including basketball, gymnastics, soccer, swimming & diving, and soccer. Participants were measured at the preseason and postseason periods. Overall, participants in all five sports were not found to change significantly in total body mass, fat mass, fat free mass, percent body fat, or body mass index from the preseason period to the postseason period at the alpha = 0.05 level. On average, the members from …

The Potential Of The Angle Of The First Rib, Head To Tubercle, In Sexing Adult Individuals In Forensic Contexts, Paige Whitney Elrod

LSU Master's Theses

Accurately assessing the sex of an adult human skeleton is fundamental in forming the biological profile used in forensic anthropology (Patil and Mody, 2005). The first rib was chosen due to its distinct shape, compact size and increased sustainability to the taphonomic processes encountered in forensic and bioarchaeological situations. The first rib has been examined in previous studies; however, these studies have focused mainly on the sternal end of the rib. This study looks at the angle created between the tubercle and head and its potential use as an indication of the sex of an individual. This angle, created by …
