METHODS: We conducted a chart review of inpatients diagnosed with splenic infarction in a Jerusalem hospital between 1990 and 2003.

RESULTS: We identified 26 cases with a mean age of 52 years. Common causes were hematologic malignancy (six cases) and intracardiac thrombus (five cases). Only three cases were associated with bacterial endocarditis. In 21 cases the splenic …

Polymorphisms Of The Dna Repair Gene Mgmt And Risk And Progression Of Head And Neck Cancer, Zhengdong Zhang, Luo Wang, Sheng Wei, Zhensheng Liu, Li-E Wang, Erich M Sturgis, Qingyi Wei

Faculty, Staff and Student Publications

Methylating agents are involved in carcinogenesis, and the DNA repair protein O(6)-methylguanine-DNA methyltransferase (MGMT) removes methyl group from O(6)-methylguanine. Genetic variation in DNA repair genes has been shown to contribute to susceptibility to squamous cell carcinoma of the head and neck (SCCHN). We hypothesize that MGMT polymorphisms are associated with risk of SCCHN. In a hospital-based case-control study of 721 patients with SCCHN and 1234 cancer-free controls frequency-matched by age, sex and ethnicity, we genotyped four MGMT polymorphisms, two in exon 3, 16195C>T and 16286C>T and two in the promoter region, 45996G>T and 46346C>A. We found …

Abdominal or chest drains were used with either improvised dextrose-electrolyte solution or commercial …

Enhanced Psychosocial Well-Being Following Participation In A Mindfulness-Based Stress Reduction Program Is Associated With Increased Natural Killer Cell Activity., Carolyn Y Fang, Diane K Reibel, Margaret L Longacre, Steven Rosenzweig, Donald E Campbell, Steven D Douglas

Marcus Institute of Integrative Health Faculty Papers

BACKGROUND: Mindfulness-based stress reduction (MBSR) programs have consistently been shown to enhance the psychosocial well-being of participants. Given the well-established association between psychosocial factors and immunologic functioning, it has been hypothesized that enhanced psychosocial well-being among MBSR participants would be associated with corresponding changes in markers of immune activity.

OBJECTIVES: The objectives of this study were to examine changes in psychosocial and immunologic measures in a heterogeneous patient sample following participation in a MBSR program.

DESIGN: A single-group, pretest/post-test design was utilized.

SETTING: The intervention was conducted at an academic health center.

Basal Insulin Requirements On Continuous Subcutaneous Insulin Infusion During The First 12 Months After Diagnosis Of Type 1 Diabetes Mellitus., Neesha Ramchandani, Mary Kristine Ellis, Shobhit Jain, Sonal Bhandari, Henry Anhalt, Noel K. Maclaren, Svetlana Ten

Manuscripts, Articles, Book Chapters and Other Papers

INTRODUCTION: While the endogenous first-phase insulin response has disappeared by the time of diagnosis of type 1 diabetes mellitus (T1DM), anecdotal evidence suggests that these patients can continue to have a second-phase insulin response during the first 12 months after diagnosis. We hypothesized that patients who are started on continuous subcutaneous insulin infusion (CSII) at the time of diagnosis of T1DM would have a lower basal insulin requirement than the 40-60% usually expected.

METHODS: We analyzed 38 patients with T1DM, age 9.9 +/- 6.4 years, 71% male, who were started on CSII within the first month of diagnosis.

RESULTS: Average …

Inspired Gas-Induced Vascular Change In Tumors With Magnetic-Resonance-Guided Near-Infrared Imaging: Human Breast Pilot Study, Colin M. Carpenter, Rebecca Rakow-Penner, Shudong Jiang, Bruce L. Daniel, Brian W. Pogue, Gary H. Glover, Keith D. Paulsen

Dartmouth Scholarship

This study investigates differences in the response of breast tumor tissue versus healthy fibroglandular tissue to inspired gases. Cycles of carbogen and oxygen gas are administered while measuring the changes with magnetic-resonance-guided near-infrared imaging in a pilot study of breast cancers. For two patients, analyses are performed with cross-correlation techniques, which measure the strength of hemodynamic modulation. The results show that the overall vasoresponse, indicated by total hemoglobin, of healthy tissue has approximately a 72% and 41% greater correlation to the gas stimulus than the tumor region, in two patients respectively, when background physiological changes are controlled. These data support …

Bold Signal In Both Ipsilateral And Contralateral Retinotopic Cortex Modulates With Perceptual Fading, Po-Jang Hsieh, Peter U. Tse

Dartmouth Scholarship

Under conditions of visual fixation, perceptual fading occurs when a stationary object, though present in the world and continually casting light upon the retina, vanishes from visual consciousness. The neural correlates of the consciousness of such an object will presumably modulate in activity with the onset and cessation of perceptual fading.

Method: In order to localize the neural correlates of perceptual fading, a green disk that had been individually set to be equiluminant with the orange background, was presented in one of the four visual quadrants; Subjects indicated with a button press whether or not the disk was subjectively visible …

Faculty, Staff and Student Publications

OBJECTIVE: We sought to determine maternal and neonatal outcomes by labor onset type and gestational age.

STUDY DESIGN: We used electronic medical records data from 10 US institutions in the Consortium on Safe Labor on 115,528 deliveries from 2002 through 2008. Deliveries were divided by labor onset type (spontaneous, elective induction, indicated induction, unlabored cesarean). Neonatal and maternal outcomes were calculated by labor onset type and gestational age.

RESULTS: Neonatal intensive care unit admissions and sepsis improved with each week of gestational age until 39 weeks (P < .001). After adjusting for complications, elective induction of labor was associated with a lower risk of ventilator use (odds ratio [OR], 0.38; 95% confidence interval [CI], 0.28-0.53), sepsis (OR, 0.36; 95% CI, 0.26-0.49), and neonatal intensive care unit admissions (OR, 0.52; 95% CI, 0.48-0.57) compared to spontaneous labor. The relative risk of hysterectomy at term was 3.21 (95% CI, 1.08-9.54) with elective induction, 1.16 (95% CI, 0.24-5.58) with indicated induction, and 6.57 (95% CI, 1.78-24.30) with cesarean without labor compared to spontaneous labor.

CONCLUSION: Some neonatal outcomes improved until 39 weeks. Babies born with elective induction …

Renin-Angiotensin System Activation Correlates With Microvascular Dysfunction In A Prospective Cohort Study Of Clinical Sepsis, Kevin C. Doerschug, Angela S. Delsing, Gregory A. Schmidt, Alix Ashare

Dartmouth Scholarship

Microvascular dysregulation characterized by hyporesponsive vessels and heterogeneous bloodflow is implicated in the pathogenesis of organ failure in sepsis. The renin-angiotensin system (RAS) affects the microvasculature, yet the relationships between RAS and organ injury in clinical sepsis remain unclear. We tested our hypothesis that systemic RAS mediators are associated with dysregulation of the microvasculature and with organ failure in clinical severe sepsis.

Indirect Costs Associated With Surgery For Low Back Pain-A Secondary Analysis Of Clinical Trial Data., Reginald Fayssoux, Neil I Goldfarb, Alexander R Vaccaro, James Harrop

College of Population Health Faculty Papers

This study examines the indirect costs associated with surgery for axial low back pain using data obtained from a prospective multicenter clinical trial that compared Charité artificial disc replacement with anterior lumbar interbody fusion using iliac crest bone graft. While 75% of study subjects reported full- or part-time employment prior to surgery, this percentage dropped to 45% at 6 weeks postoperatively. Return to preoperative employment levels occurred at approximately 6 months postoperatively. Two years after surgery, employment levels were 16% higher than preoperative levels. Lost productivity related to absenteeism resulted in lost wages averaging $2884 per patient during the first …

Humoral Immunity In Tuberculin Skin Test Anergy And Its Role In High-Risk Persons Exposed To Active Tuberculosis, Liliana Encinales, Joaquin Zuñiga, Julio Granados-Montiel, Maria Yunis, Julio Granados, Ingrid Almeciga, Olga Clavijo, Carlos Awad, Vilma Collazos, María Inés Vargas-Rojas, José Luis Bañales-Mendez, Lilia Vazquez-Castañeda, Joel N Stern, Viviana Romero, Masha Fridkis-Hareli, Masha Frindkis-Hareli, Daniel Terreros, Marcelo Fernandez-Viña, Edmond J Yunis

Faculty, Staff and Student Publications

The most common test to identify latent tuberculosis is the tuberculin skin test that detects T cell responses of delayed type hypersensitivity type IV. Since it produces false negative reactions in active tuberculosis or in high-risk persons exposed to tuberculosis patients as shown in this report, we studied antibody profiles to explain the anergy of such responses in high-risk individuals without active infection. Our results showed that humoral immunity against tuberculin, regardless of the result of the tuberculin skin test is important for protection from active tuberculosis and that the presence of high antibody titers is a more reliable indicator …

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 …

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 …

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 …

Resting State Default-Mode Network Connectivity In Early Depression Using A Seed Region-Of-Interest Analysis: Decreased Connectivity With Caudate Nucleus., Robyn Bluhm, Peter Williamson, Ruth Lanius, Jean Theberge, Maria Densmore, Robert Bartha, Richard Neufeld, Elizabeth Osuch

Department of Medicine Publications

AIM: Reports on resting brain activity in healthy controls have described a default-mode network (DMN) and important differences in DMN connectivity have emerged for several psychiatric conditions. No study to date, however, has investigated resting-state DMN in relatively early depression before years of medication treatment. The objective of the present study was, therefore, to investigate the DMN in patients seeking help from specialized mental health services for the first time for symptoms of depression.

METHODS: Fourteen depressed subjects and 15 matched controls were scanned using 4-T functional magnetic resonance imaging while resting with eyes closed. All but one subject was …

Journal Articles: Pathology and Microbiology

BACKGROUND: Cyclin D1-negative mantle cell lymphoma is difficult to distinguish from other small B-cell lymphomas. The clinical and pathological characteristics of patients with this form of lymphoma have not been well defined. Overexpression of the transcription factor SOX11 has been observed in conventional mantle cell lymphoma. The aim of this study was to determine whether this gene is expressed in cyclin D1-negative mantle cell lymphoma and whether its detection may be useful to identify these tumors.

DESIGN AND METHODS: The microarray database of 238 mature B-cell neoplasms was re-examined. SOX11 protein expression was investigated immunohistochemically in 12 cases of cyclin …

This study aimed to identify the variables that influence parental treatment decisions after a prenatal diagnosis of congenital heart disease (CHD). The authors reviewed all cases of prenatally diagnosed structural CHD from August 1998 to December 2006 at their center. The following variables were studied as potential predictors of parental intent to treat: maternal age, race, insurance status, obstetric history, fetal gender, univentricular versus biventricular cardiac physiology, and fetal chromosomal abnormality. Uni- and multivariable logistic regression analyses were performed. In the review, 252 consecutive cases of prenatally diagnosed CHD were identified. Of these, 204 women pursued full medical treatment, whereas …

Intracranial Eeg Reveals A Time- And Frequency-Specific Role For The Right Inferior Frontal Gyrus And Primary Motor Cortex In Stopping Initiated Responses, Nicole Swann, Nitin Tandon, Ryan Canolty, Timothy M Ellmore, Linda K Mcevoy, Stephen Dreyer, Michael Disano, Adam R Aron

Faculty, Staff and Student Publications

Inappropriate response tendencies may be stopped via a specific fronto/basal ganglia/primary motor cortical network. We sought to characterize the functional role of two regions in this putative stopping network, the right inferior frontal gyrus (IFG) and the primary motor cortex (M1), using electocorticography from subdural electrodes in four patients while they performed a stop-signal task. On each trial, a motor response was initiated, and on a minority of trials a stop signal instructed the patient to try to stop the response. For each patient, there was a greater right IFG response in the beta frequency band ( approximately 16 Hz) …

Antidepressant-Induced Mania With Concomitant Mood Stabilizer In Patients With Comorbid Substance Abuse And Bipolar Disorder., Daniel Z Lieberman, George Kolodner, Suena H Massey, Kenneth P Williams

Psychiatry and Behavioral Sciences Faculty Publications

Antidepressant use in the treatment of bipolar disorder is controversial due the risks of affective switching and cycle acceleration. Studies of non-comorbid samples suggest that the risk can be mitigated with the use of a concomitant mood stabilizer. However, the majority of patients with bipolar disorder will experience a comorbid substance use disorder and little is known about these individuals because they are typically excluded from clinical trials. Patients entering a substance abuse treatment program who had a history of bipolar disorder were interviewed to evaluate antidepressant-induced affective switching with and without concomitant mood stabilizer. Among 41 comorbid participants, the …
