Evaluating The Effectiveness Of Psychosocial Interventions For Individuals With Visible Differences: A Systematic Review Of The Empirical Literature., Alyson Bessell, Timothy P. Moss Sep 2007

Evaluating The Effectiveness Of Psychosocial Interventions For Individuals With Visible Differences: A Systematic Review Of The Empirical Literature., Alyson Bessell, Timothy P. Moss

More Faculty of Health Research

The objective of this review was to systematically identify and evaluate all known studies testing empirically the efficacy of psychosocial intervention programmes for adults with visible differences. Twelve papers met the inclusion criteria. None of the papers demonstrated adequately the clinical effectiveness of the interventions. The review concluded that further research was needed to demonstrate adequately the effectiveness of existing interventions, and a greater number of Randomised Controlled Trials and experimental studies were required to increase the methodological validity of intervention studies.


The Shift From Defined Benefit Pensions To 401(K) Plans And The Pension Assets Of The Baby Boom Cohort, James Poterba, Steven Venti, David A. Wise Aug 2007

The Shift From Defined Benefit Pensions To 401(K) Plans And The Pension Assets Of The Baby Boom Cohort, James Poterba, Steven Venti, David A. Wise

Dartmouth Scholarship

The rise of 401(k) plans and the decline of defined benefit plans will have an important effect on the wealth of future retirees. Changing demographic structure also will affect the aggregate stock of retirement wealth. We project the stock of assets held in retirement plans and the average retirement saving of retirees through 2040. Our projections show large increases in wealth at retirement, especially if the returns on corporate equities are comparable with historical returns. Retirement wealth will grow, however, even if equity returns fall substantially below their historical level.

Despite several investigations, the transcriptional mechanisms that regulate the expression of both type I collagen genes (COL1A1 and COL1A2) in either physiological or pathological situations, such as scleroderma, are not completely known. We have investigated the role of hc-Krox transcription factor on type I collagen expression by human dermal fibroblasts. hc-Krox exerted a stimulating effect on type I collagen protein synthesis and enhanced the corresponding mRNA steady-state levels of COL1A1 and COL1A2 in foreskin fibroblasts (FF), adult normal fibroblasts (ANF), and scleroderma fibroblasts (SF). Forced hc-Krox expression was found to up-regulate COL1A1 transcription through a -112/-61-bp sequence in FF, ANF, …

Pathology and Laboratory Medicine Faculty Publications

Oxidative stress is thought to play a role in the pathogenesis of Alzheimer's disease (AD) and increased oxidative DNA damage has been observed in brain tissue from AD patients. Base excision repair (BER) is the primary DNA repair pathway for small base modifications such as alkylation, deamination and oxidation. In this study, we have investigated alterations in the BER capacity in brains of AD patients. We employed a set of functional assays to measure BER activities in brain tissue from short post-mortem interval autopsies of 10 sporadic AD patients and 10 age-matched controls. BER activities were also measured in brain …

Walking Age Does Not Explain Term Versus Preterm Difference In Bone Geometry, Haifa Abou Samra, Bonny Specker Jul 2007

Walking Age Does Not Explain Term Versus Preterm Difference In Bone Geometry, Haifa Abou Samra, Bonny Specker

Ethel Austin Martin Program Publications

OBJECTIVE: To elucidate the relationship between bone geometry and onset of walking in former term and preterm children.
STUDY DESIGN: We conducted a cross-sectional study of 128 preschool children aged 3 to 5 years who underwent peripheral quantitative computerized tomography measures of bone size at the distal tibia. Linear models were developed, stratifying by sex, to determine whether bone differences between children born term and preterm were caused by differences in walking age.
RESULTS: Children with a history of preterm birth walked later than children born at term (12.4 +/- 0.5 versus 10.9 +/- 0.2 months; P = .004); however, …

A Larger Sense Of Purpose: Dentistry And Society, David A. Nash Jul 2007

A Larger Sense Of Purpose: Dentistry And Society, David A. Nash

Oral Health Science Faculty Publications

Dentistry is undergoing a subtle shift away from being a profession to becoming a business. The two cultures of professionalism and business are contrasted. Among the forces driving this change are the emphasis on esthetics in dentistry and the increasing inability of a large class of patients to access dentistry on a business basis. The shift toward dentistry as a business entails the unhealthy transition toward regarding patients as means to satisfy the dentist's ends rather than patients' health being an end in itself. Dentists run the risk of "objectivifying" rather than "humanizing" patients. This trend must be overcome with …

College of Population Health Faculty Papers

Migraine headache is a highly prevalent, chronic, episodic disorder that is associated with high direct and indirect costs. Migraine headache impacts not only patients, but also their employers due to substantial decreases in workplace productivity. Despite the prevalence and clinical and economic burdens of migraine, no national efforts to develop and implement standardized measures of quality of care have been made. The objective of this study was to collect and report on existing quality of care measures for migraine that could be suitable for quality measurement at the health-plan level. Published literature, the Agency for Healthcare Research and Quality's National …


Azithromycin In The Extremely Low Birth Weight Infant For The Prevention Of Bronchopulmonary Dysplasia: A Pilot Study, Hubert O. Ballard, Michael I. Anstead, Lori A. Shook Jun 2007

Azithromycin In The Extremely Low Birth Weight Infant For The Prevention Of Bronchopulmonary Dysplasia: A Pilot Study, Hubert O. Ballard, Michael I. Anstead, Lori A. Shook

Pediatrics Faculty Publications

BACKGROUND: Azithromycin reduces the severity of illness in patients with inflammatory lung disease such as cystic fibrosis and diffuse panbronchiolitis. Bronchopulmonary dysplasia (BPD) is a pulmonary disorder which causes significant morbidity and mortality in premature infants. BPD is pathologically characterized by inflammation, fibrosis and impaired alveolar development. The purpose of this study was to obtain pilot data on the effectiveness and safety of prophylactic azithromycin in reducing the incidence and severity of BPD in an extremely low birth weight (< or = 1000 grams) population.

METHODS: Infants < or = 1000 g birth weight admitted to the University of Kentucky Neonatal Intensive Care Unit (level III, regional referral center) from 9/1/02-6/30/03 were eligible for this pilot study. The pilot study was double-blinded, randomized, and placebo-controlled. Infants were randomized to treatment or placebo within 12 hours of beginning mechanical ventilation (IMV) and within 72 hours of birth. The treatment group received azithromycin 10 mg/kg/day for 7 days followed by 5 mg/kg/day for the duration of the study. Azithromycin or placebo was continued until the infant no longer required IMV or supplemental oxygen, to a maximum of 6 weeks. Primary endpoints were incidence of BPD as defined by oxygen requirement at 36 weeks gestation, post-natal steroid use, days of IMV, and mortality. Data was analyzed by intention to treat using Chi-square and ANOVA.

RESULTS: A total of 43 extremely premature infants were enrolled in this pilot study. Mean gestational age and …


Acute Proximal Hamstring Rupture, Steven B. Cohen, James Bradley Jun 2007

Acute Proximal Hamstring Rupture, Steven B. Cohen, James Bradley

Department of Orthopaedic Surgery Faculty Papers

Hamstring strain is common in athletes, and both diagnosis and surgical treatment of this injury are becoming more common. Nonsurgical treatment of complete ruptures has resulted in complications such as muscle weakness and sciatic neuralgia. Surgical treatment recently has been advocated to repair the complete rupture of the hamstring tendons from the ischial tuberosity. Surgical repair involves a transverse incision in the gluteal crease, protection of the sciatic nerve, mobilization of the ruptured tendons, and repair to the ischial tuberosity with the use of suture anchors. Reports in the literature of surgical treatment of proximal hamstring rupture are few, and …

Concave Pit-Containing Scaffold Surfaces Improve Stem Cell-Derived Osteoblast Performance And Lead To Significant Bone Tissue Formation., Antonio Graziano, Riccardo D'Aquino, Maria Gabriella Cusella-De Angelis, Gregorio Laino, Adriano Piattelli, Maurizio Pacifici, Alfredo De Rosa, Gianpaolo Papaccio

Department of Orthopaedic Surgery Faculty Papers

BACKGROUND: Scaffold surface features are thought to be important regulators of stem cell performance and endurance in tissue engineering applications, but details about these fundamental aspects of stem cell biology remain largely unclear.

METHODOLOGY AND FINDINGS: In the present study, smooth clinical-grade lactide-coglyolic acid 85:15 (PLGA) scaffolds were carved as membranes and treated with NMP (N-metil-pyrrolidone) to create controlled subtractive pits or microcavities. Scanning electron and confocal microscopy revealed that the NMP-treated membranes contained: (i) large microcavities of 80-120 microm in diameter and 40-100 microm in depth, which we termed primary; and (ii) smaller microcavities of 10-20 microm in diameter …

Acquisition Of A Natural Resistance Gene Renders A Clinical Strain Of Methicillin-Resistant Staphylococcus Aureus Resistant To The Synthetic Antibiotic Linezolid, Seok-Ming Toh, Liqun Xiong, Cesar A Arias, Maria V Villegas, Karen Lolans, John Quinn, Alexander S Mankin

Faculty, Staff and Student Publications

Linezolid, which targets the ribosome, is a new synthetic antibiotic that is used for treatment of infections caused by Gram-positive pathogens. Clinical resistance to linezolid, so far, has been developing only slowly and has involved exclusively target site mutations. We have discovered that linezolid resistance in a methicillin-resistant Staphylococcus aureus hospital strain from Colombia is determined by the presence of the cfr gene whose product, Cfr methyltransferase, modifies adenosine at position 2503 in 23S rRNA in the large ribosomal subunit. The molecular model of the linezolid-ribosome complex reveals localization of A2503 within the drug binding site. The natural function of …

BACKGROUND: Management of degenerative spondylolisthesis with spinal stenosis is controversial. Surgery is widely used, but its effectiveness in comparison with that of nonsurgical treatment has not been demonstrated in controlled trials.

METHODS: Surgical candidates from 13 centers in 11 U.S. states who had at least 12 weeks of symptoms and image-confirmed degenerative spondylolisthesis were offered enrollment in a randomized cohort or an observational cohort. Treatment was standard decompressive laminectomy (with or without fusion) or usual nonsurgical care. The primary outcome measures were the Medical Outcomes Study 36-Item Short-Form General Health Survey (SF-36) bodily pain and physical function scores (100-point scales, …


The Kinesin-13 Proteins Kif2a, Kif2b, And Kif2c/Mcak Have Distinct Roles During Mitosis In Human Cells, Amity L. Manning, Neil J. Ganem, Samuel F. Bakhoum, Michael Wagenbach, Linda Wordeman, Duane A. Compton May 2007

The Kinesin-13 Proteins Kif2a, Kif2b, And Kif2c/Mcak Have Distinct Roles During Mitosis In Human Cells, Amity L. Manning, Neil J. Ganem, Samuel F. Bakhoum, Michael Wagenbach, Linda Wordeman, Duane A. Compton

Dartmouth Scholarship

The human genome has three unique genes coding for kinesin-13 proteins called Kif2a, Kif2b, and MCAK (Kif2c). Kif2a and MCAK have documented roles in mitosis, but the function of Kif2b has not been defined. Here, we show that Kif2b is expressed at very low levels in cultured cells and that GFP-Kif2b localizes predominately to centrosomes and midbodies, but also to spindle microtubules and transiently to kinetochores. Kif2b-deficient cells assemble monopolar or disorganized spindles. Chromosomes in Kif2b-deficient cells show typical kinetochore-microtubule attachments, but the velocity of movement is reduced ∼80% compared with control cells. Some Kif2b-deficient cells attempt anaphase, but the …


Detecting Agency From The Biological Motion Of Veridical Vs Animated Agents, Raymond A. Mar, William M. Kelley, Todd F. Heatherton, C. Neil Macrae May 2007

Detecting Agency From The Biological Motion Of Veridical Vs Animated Agents, Raymond A. Mar, William M. Kelley, Todd F. Heatherton, C. Neil Macrae

Dartmouth Scholarship

The ability to detect agency is fundamental for understanding the social world. Underlying this capacity are neural circuits that respond to patterns of intentional biological motion in the superior temporal sulcus and temporoparietal junction. Here we show that the brain's blood oxygenation level dependent (BOLD) response to such motion is modulated by the representation of the actor. Dynamic social interactions were portrayed by either live-action agents or computer-animated agents, enacting the exact same patterns of biological motion. Using an event-related design, we found that the BOLD response associated with the perception and interpretation of agency was greater when identical physical …


Differential Neuromuscular Training Effects On Acl Injury Risk Factors In"High-Risk" Versus "Low-Risk" Athletes, Gregory D. Myer, Kevin R. Ford, Jensen L. Brent, Timothy E. Hewett May 2007

Differential Neuromuscular Training Effects On Acl Injury Risk Factors In"High-Risk" Versus "Low-Risk" Athletes, Gregory D. Myer, Kevin R. Ford, Jensen L. Brent, Timothy E. Hewett

Kinesiology and Health Promotion Faculty Publications

BACKGROUND: Neuromuscular training may reduce risk factors that contribute to ACL injury incidence in female athletes. Multi-component, ACL injury prevention training programs can be time and labor intensive, which may ultimately limit training program utilization or compliance. The purpose of this study was to determine the effect of neuromuscular training on those classified as "high-risk" compared to those classified as "low-risk." The hypothesis was that high-risk athletes would decrease knee abduction moments while low-risk and control athletes would not show measurable changes.

METHODS: Eighteen high school female athletes participated in neuromuscular training 3x/week over a 7-week period. Knee kinematics and …


A Review Of The Association Between Congestive Heart Failure And Cognitive Impairment., Michael B. Cohen, Paul J. Mather May 2007

A Review Of The Association Between Congestive Heart Failure And Cognitive Impairment., Michael B. Cohen, Paul J. Mather

Division of Cardiology Faculty Papers

Heart failure is a growing epidemic with an estimated 5 million Americans suffering from this condition. Several clinical trials have demonstrated a high correlation between congestive heart failure (CHF) and cognitive impairment. The severity of cognitive impairment correlates positively with the degree of CHF. The underlying mechanism for cognitive impairment remains unclear but appears to be related to cerebral hypoperfusion and impaired cerebral reactivity with selective impairment of verbal memory and attention domains. Furthermore, cognitive dysfunction represents one aspect of frailty, a novel concept that encompasses a range of clinical conditions that results in functional impairment in patients with heart …

Expansion Of The Calcium Hypothesis Of Brain Aging And Alzheimer's Disease: Minding The Store, Olivier Thibault, John C. Gant, Philip W. Landfield

Pharmacology and Nutritional Sciences Faculty Publications

Evidence accumulated over more than two decades has implicated Ca2+ dysregulation in brain aging and Alzheimer's disease (AD), giving rise to the Ca2+ hypothesis of brain aging and dementia. Electrophysiological, imaging, and behavioral studies in hippocampal or cortical neurons of rodents and rabbits have revealed aging-related increases in the slow afterhyperpolarization, Ca2+ spikes and currents, Ca2+transients, and L-type voltage-gated Ca2+ channel (L-VGCC) activity. Several of these changes have been associated with age-related deficits in learning or memory. Consequently, one version of the Ca2+ hypothesis has been that increased L-VGCC activity drives many of the other Ca2+-related biomarkers of hippocampal aging. …


Functional Dissociation In Frontal And Striatal Areas For Processing Of Positive And Negative Reward Information, Xun Liu, David K. Powell, Hongbin Wang, Brian T. Gold, Christine R. Corbly, Jane E. Joseph Apr 2007

Functional Dissociation In Frontal And Striatal Areas For Processing Of Positive And Negative Reward Information, Xun Liu, David K. Powell, Hongbin Wang, Brian T. Gold, Christine R. Corbly, Jane E. Joseph

Neuroscience Faculty Publications

Reward-seeking behavior depends critically on processing of positive and negative information at various stages such as reward anticipation, outcome monitoring, and choice evaluation. Behavioral and neuropsychological evidence suggests that processing of positive (e.g., gain) and negative (e.g., loss) reward information may be dissociable and individually disrupted. However, it remains uncertain whether different stages of reward processing share certain neural circuitry in frontal and striatal areas, and whether distinct but interactive systems in these areas are recruited for positive and negative reward processing. To explore these issues, we used a monetary decision-making task to investigate the roles of frontal and striatal …

OBJECTIVE: The purpose of this study was to assess the effectiveness and tolerability of atomoxetine during acute treatment of attention-deficit/hyperactivity disorder (ADHD) in 5 and 6 year olds.

METHOD: Twenty two children (male n = 19, 86%) with ADHD were treated with atomoxetine for 8 weeks in a three-site, open-label pilot study. Dosing was flexible, with titration to a maximum of 1.8 mg/kg per day. Parent education on behavior management was provided as part of each pharmacotherapy visit.

RESULTS: Subjects demonstrated a mean decrease of 20.68 points (SD = 12.80, p < 0.001)) on the ADHD Rating Scale-IV (ADHD-IV-RS) total score, 10.18 (SD = 7.48, p < 0.001) on the inattentive subscale and 10.50 (SD = 7.04, p < 0.001) on the hyperactive/impulsive subscale. Clinical Global Impression-Severity (CGI-S) was improved in 82% of the children (95% CI, 66-98%) and Children's Global Assessment (CGAS) scores improved 18.91 points on average (SD = 12.20, p < 0.001). The mean final dose of atomoxetine was 1.25 mg/kg per day (SD = 0.35 mg/kg per day). Mood lability was the most commonly reported adverse event (n = 12, 54.5%). Eleven subjects (50%) reported decreased appetite and a mean weight loss of 1.04 kg (SD = 0.80 kg) (p < 0.001) was observed for the group. Vital sign changes were mild and not clinically significant. There were no discontinuations due to adverse events or lack of efficacy.

CONCLUSION: Atomoxetine was generally effective for reducing core ADHD …
