Dr Robert Brown
Elevated plasma concentrations of HDL cholesterol (HDL-C) are associated with protection from atherosclerotic cardiovascular disease. Animal models indicate that decreased expression of endothelial lipase (LIPG) is inversely associated with HDL-C levels, and genome-wide association studies have identified LIPG variants as being associated with HDL-C levels in humans. We hypothesized that loss-of-function mutations in LIPG may result in elevated HDL-C and therefore performed deep resequencing of LIPG exons in cases with elevated HDL-C levels and controls with decreased HDL-C levels. We identified a significant excess of nonsynonymous LIPG variants unique to cases with elevated HDL-C. In vitro lipase activity assays demonstrated …
Prediction Of Radiation Pneumonitis By Dose-Volume Histogram Parameters In Lung Cancer--A Systematic Review, George Rodrigues, Michael Lock, David D'Souza, Edward Yu, Jake Van Dyk
Prediction Of Radiation Pneumonitis By Dose-Volume Histogram Parameters In Lung Cancer--A Systematic Review, George Rodrigues, Michael Lock, David D'Souza, Edward Yu, Jake Van Dyk
Michael Lock
BACKGROUND AND PURPOSE: To perform a systematic review of the predictive ability of various dose-volume histogram (DVH) parameters (V(dose), mean lung dose (MLD), and normal tissue complication probability (NTCP)) in the incidence of radiation pneumonitis (RP) caused by external-beam radiation therapy.
METHODS AND MATERIALS: Studies assessing the relationship between CT-based DVH reduction parameters and RP rate in radically treated lung cancer were eligible for the review. Synonyms for RP, lung cancer, DVH and its associated parameters (NTCP, V(20), V(30), MLD) were combined in a search strategy involving electronic databases, secondary reference searching, and consultation with experts. Individual or group data …
Tubercular Pancreatic Abscess Presenting As Fever And Cystic Pancreatic Lesion With Endoscopic Management., Jonathan Fenkel, Maya Spodik, Bheema Singu, Anthony Infantolino, Sandeep Deshmukh, David Loren
Tubercular Pancreatic Abscess Presenting As Fever And Cystic Pancreatic Lesion With Endoscopic Management., Jonathan Fenkel, Maya Spodik, Bheema Singu, Anthony Infantolino, Sandeep Deshmukh, David Loren
Sandeep Deshmukh
Isolated pancreatic tuberculosis is a rare presentation of tubercular infection. There are few reported cases of pancreatic tuberculosis diagnosed by endoscopic ultrasound with fine-needle aspiration (EUS FNA), though EUS is often used in the evaluation of pancreatic cystic lesions. We present a case of a tubercular pancreatic abscess presenting as a cystic lesion in a patient with undiagnosed immunodeficiency. The abscess was aspirated by EUS FNA and treated with endoscopic drainage and anti-mycobacterial medications.

Michael P Savage M.D.
BACKGROUND: Treatment of stenosis in saphenous-vein grafts after coronary-artery bypass surgery is a difficult challenge. The purpose of this study was to compare the effects of stent placement with those of balloon angioplasty on clinical and angiographic outcomes in patients with obstructive disease of saphenous-vein grafts.
METHODS: A total of 220 patients with new lesions in aortocoronary-venous bypass grafts were randomly assigned to placement of Palmaz-Schatz stents or standard balloon angioplasty. Coronary angiography was performed during the index procedure and six months later.
RESULTS: As compared with the patients assigned to angioplasty, those assigned to stenting had a higher rate …

The incidence of liver disease progression among subjects with histologically advanced but compensated chronic hepatitis C is incomplete. The Hepatitis C Antiviral Long-term Treatment against Cirrhosis Trial was a randomized study of 3.5 years of maintenance peginterferon treatment on liver disease progression among patients who had not cleared virus on peginterferon and ribavirin therapy. Patients were followed subsequently off therapy. Because maintenance peginterferon treatment did not alter liver disease progression, we analyzed treated and control patients together. Among 1,050 subjects (60% advanced fibrosis, 40% cirrhosis), we determined the rate of progression to cirrhosis over 4 years and of clinical outcomes …

Insurance Status And Length Of Stay For Involuntarily Hospitalized Patients, William Fisher, Paul Barreira, Alisa Lincoln, Lorna Simon, Andrew White, Kristen Roy-Bujnowski, Marylou Sudders
Alisa Lincoln
General and private psychiatric hospitals are becoming increasingly common as sites for involuntary hospitalization. Unlike the public facilities that these settings are supplanting, these hospitals must pay strict attention to issues associated with reimbursement, insurance status, and managed care. This article examines the effects of insurance status on length of stay for involuntarily hospitalized patients in general and private hospitals in Massachusetts. Using a two-stage sampling procedure, data on episodes of involuntary hospitalization were gathered and assessed using multiple regression. The primary effect was found between patients with Medicare, who had the longest stays, and individuals who were uninsured, who …

Privatized Medicaid Managed Care In Massachusetts: Disposition In Child And Adolescent Mental Health Emergencies, Joanne Nicholson, Stephen Young, Lorna Simon, William Fisher, Anne Bateman
Privatized Medicaid Managed Care In Massachusetts: Disposition In Child And Adolescent Mental Health Emergencies, Joanne Nicholson, Stephen Young, Lorna Simon, William Fisher, Anne Bateman
Joanne Nicholson
Data from child and adolescent emergency mental health screening episodes prior and subsequent to privatized Medicaid managed care in Massachusetts are used to investigate the relationship between payer source and disposition and to compare the match between clinical need and disposition level of care. Having Medicaid as the payer in the post-Medicaid managed care period decreased the odds of hospitalization by nearly 60%. None of the clinical need variables that contributed to hospitalization for Medicaid episodes in the pre-Medicaid managed care period were significant in the post-Medicaid managed care period. Multiple forces shaping professional standards, decision making, and quality of …

Fathers With Severe Mental Illness: Characteristics And Comparisons, Joanne Nicholson, Margaret Nason, Anne Calabresi, Regina Yando
Joanne Nicholson
Among patients with severe mental illness attending a large, urban, outpatient mental health clinic, fathers are described and compared with nonfathers and with mothers on demographic, clinical, and child-related characteristics, and on resources and service needs. While fathers and nonfathers with mental illness differed significantly on most variables, fathers and mothers with mental illness were remarkably similar except on child-related characteristics. Issues regarding fathers' experiences and service needs are discussed.

A Qualitative Study Of Programs For Parents With Serious Mental Illness And Their Children: Building Practice-Based Evidence, Joanne Nicholson, Beth Hinden, Kathleen Biebel, Alexis Henry, Judith Katz-Leavy
Joanne Nicholson
The rationale for the development of effective programs for parents with serious mental illness and their children is compelling. Using qualitative methods and a grounded theory approach with data obtained in site visits, seven existing programs for parents with mental illness and their children in the United States are described and compared across core components: target population, theory and assumptions, funding, community and agency contexts, essential services and intervention strategies, moderators, and outcomes. The diversity across programs is strongly complemented by shared characteristics, the identification of which provides the foundation for future testing and the development of an evidence base. …
The Responsiveness Of State Mental Health Authorities To Parents With Mental Illness, Kathleen Biebel, Joanne Nicholson, Valerie Williams, Beth Hinden
The Responsiveness Of State Mental Health Authorities To Parents With Mental Illness, Kathleen Biebel, Joanne Nicholson, Valerie Williams, Beth Hinden
Joanne Nicholson
The majority of adults with serious mental illness living in the community are parents, many of whom may be receiving services from State Mental Health Authorities (SMHA). Innovative intervention approaches are available to improve outcomes for these parents and their children. Analyses of SMHA and state-level data, as well as qualitative interviews of administrators, service providers, and consumers, underscore the importance of organizational structure and philosophy, an advocacy presence, and available funding to SMHA efforts on behalf of parents and their families.

Creating Job Opportunities For People With Psychiatric Disabilities At A University-Based Research Center, Alexis Henry, Joanne Nicholson, Jonathan Clayfield, Susan Phillips, Lawrence Stier
Joanne Nicholson
The consumer empowerment movement has led to an increase in opportunities for people with psychiatric disabilities to take on roles in the development and delivery of mental health services. However, to date there has been less involvement of people with psychiatric disabilities in services research. In this paper, we describe our experiences creating employment opportunities for people with psychiatric disabilities in a university-based mental health services research center. Working with two local clubhouse programs we developed research assistant positions using both transitional and supported employment approaches. We describe the development of the jobs, employee characteristics, the orientation and training provided …
"Sylvia Frumkin" Has A Baby: A Case Study For Policymakers, Joanne Nicholson, Jeffrey Geller, William Fisher
"Sylvia Frumkin" Has A Baby: A Case Study For Policymakers, Joanne Nicholson, Jeffrey Geller, William Fisher
Joanne Nicholson
"Sylvia Frumkin" was a pseudonym given to a 32-year-old woman with chronic mental illness described by Susan Sheehan in her books Is There No Place on Earth for Me? This paper presents the case of "Gloria Morrison," a patient similar to Ms. Frumkin, who is also a mother. Issues raised by the case in three areas are discussed. Issues for the service delivery system include developing better assessment, prediction, and reduction of the risk that a parent's mental illness may pose to a child's safety and well-being; targeting supportive and educational interventions to relatives and foster parents caring for children …

A Comparison Of Mothers With Co-Occurring Disorders And Histories Of Violence Living With Or Separated From Minor Children, Joanne Nicholson, Norma Finkelstein, Valerie Williams, Jennifer Thom, Chanson Noether, Megan Devilbiss
Joanne Nicholson
Data from the Women with Co-occurring Disorders and Histories of Violence Study are used to examine characteristics distinguishing mothers currently providing care for all their minor children (n = 558) from mothers separated from one or more minor children (n = 1396). Mothers are described and compared on background characteristics and experiences, well-being and current functioning, situational context, and services used. Analyses control for number of children, race, and years of education. Mothers separated from children have more children, less education, have more often been homeless, in juvenile detention or jail, and have lower incomes than mothers living with all …

The Invisible Children's Project: Key Ingredients Of An Intervention For Parents With Mental Illness, Beth Hinden, Kathleen Biebel, Joanne Nicholson, Liz Mehnert
Joanne Nicholson
This study used a collective case study design to identify key ingredients of the Invisible Children's Project, an intervention program for families in which a parent has a mental illness. Data were obtained from interviews with parents and service providers, and from family file records. Qualitative analyses were used to generate hypotheses regarding key ingredients and targeted outcomes, and to develop a testable intervention model. Key ingredients were defined as core processes, essential services, and mediators. Strong convergence across parents and providers suggested core processes defined by family-centered, strengths-based, emotionally supportive, and comprehensive approaches; essential services including family case management, …
Responding To Depression In Parents, Joanne Nicholson, Jonathan Clayfield
Responding To Depression In Parents, Joanne Nicholson, Jonathan Clayfield
Joanne Nicholson
Pediatric professionals may naturally view themselves as gatekeepers or facilitators of access to mental health services for children, but may not see themselves as the first line of "defense" for parents with mental health issues. However, about two thirds of women who meet criteria for affective disorders, and slightly more than half of the men who do, are parents. Given that the average age of onset for affective disorders is several years after the birth of first children, parental depression may initially come to the attention of pediatric providers, the most likely professionals with whom parents have contact prior to …

Impact Of Medicaid Managed Care On Child And Adolescent Emergency Mental Health Screening In Massachusetts, Joanne Nicholson, Stephen Young, Lorna Simon, Anne Bateman, William Fisher
Joanne Nicholson
OBJECTIVE: The study evaluated the impact of Medicaid managed care on decision making during emergency mental health screening and the outcomes of such screening for children and adolescents. METHODS: Data on client attributes and on system characteristics (payer, referral source, and disposition) were available for 297 Medicaid and non-Medicaid episodes of emergency mental health screening that occurred one year before the implementation of a statewide managed Medicaid program in Massachusetts and 393 episodes that occurred one year after implementation. Outcomes included changes in the volume of service provided and in the pattern of dispositions, particularly inpatient admissions. RESULTS: Although the …
A National Survey Of State Mental Health Authority Programs And Policies For Clients Who Are Parents: A Decade Later, Kathleen Biebel, Joanne Nicholson, Jeffrey Geller, William Fisher
A National Survey Of State Mental Health Authority Programs And Policies For Clients Who Are Parents: A Decade Later, Kathleen Biebel, Joanne Nicholson, Jeffrey Geller, William Fisher
Joanne Nicholson
This study presents a survey of State Mental Health Authorities' (SMHA) programs and policies addressing the needs of adult clients in their role as parent. Six program and policy areas (parent status identification, parent-focused residential programs, parent functioning assessment, outpatient services for parents, policies for hospitalized parents, and policies for hospitalized pregnant women) are examined. Results of the most recent 1999 survey are compared with results from a similar 1990 survey. This comparison reveals that the majority of SMHAs continue to overlook adult clients in their parenting role, and few SMHA programs and policies address issues of parenting.

BACKGROUND: It is unclear whether the disproportionately higher incidence and mortality from colorectal cancer among blacks compared with whites reflect differences in health-care utilization or colorectal cancer susceptibility. METHODS: A total of 60, 572 non-Hispanic white and black participants in the ongoing Prostate, Lung, Colorectal, and Ovarian (PLCO) Cancer Screening Trial underwent trial-sponsored screening flexible sigmoidoscopy (FSG) without biopsy at baseline in 10 geographically dispersed centers from November 1993 to July 2001. Subjects with polyps or mass lesions detected by FSG were referred to their physicians for diagnostic workup, the cost of which was not covered by PLCO. The records …

Chyke A. Doubeni
PURPOSE: Residing in deprived areas may increase risk of mortality beyond that explained by a person's own SES-related factors and lifestyle. The aim of this study was to examine the relation between neighborhood socioeconomic deprivation and all-cause, cancer- and cardiovascular disease (CVD)-specific mortality for men and women after accounting for education and other important person-level risk factors. METHODS: In the longitudinal NIH-AARP Study, we analyzed data from healthy participants, ages 50-71 years at study baseline (1995-1996). Deaths (n = 33831) were identified through December 2005. Information on census tracts was obtained from the 2000 US Census. Cox models estimated hazard …

Early Course Of Nicotine Dependence In Adolescent Smokers, Chyke Doubeni, George Reed, Joseph Difranza
Chyke A. Doubeni
OBJECTIVE: The goal was to characterize the early course of nicotine dependence. METHODS: Data were collected from 1246 sixth-graders in a 4-year (2002-2006) prospective study using 11 individual interviews. Subjects were monitored for 10 symptoms of dependence by using the Hooked on Nicotine Checklist. The bidirectional prospective relationship between the intensity of dependence (number of symptoms) and smoking frequency was examined by using cross-lagged analyses. RESULTS: Of the 370 subjects who had inhaled from a cigarette, 62% smoked at least once per month, 53% experienced dependence symptoms, and 40% experienced escalation to daily smoking. Smoking frequency predicted the number of …

Likelihood Of Missed And Recurrent Adenomas In The Proximal Versus The Distal Colon, Adeyinka Laiyemo, Chyke Doubeni, Andrew Sanderson, Paul Pinsky, Dilhana Badurdeen, V. Doria-Rose, Pamela Marcus, Robert Schoen, Elaine Lanza, Arthur Schatzkin, Amanda Cross
Chyke A. Doubeni
BACKGROUND: Colonoscopy may be less efficacious in reducing colorectal cancer mortality in the proximal compared with the distal colon. A greater likelihood for missed and recurrent adenomas in the proximal colon may contribute to this phenomenon.
OBJECTIVE: To examine whether a proximal adenoma is associated with the risk and location of missed and recurrent adenomas.
DESIGN: Prospective.
SETTING: Polyp Prevention Trial.
PARTICIPANTS: A total of 1864 patients with an adenoma at baseline underwent a follow-up colonoscopy 4 years later (adenoma recurrence). Of these, 1731 underwent a clearing colonoscopy 1 year after the baseline examination (missed adenoma).
MAIN OUTCOME MEASUREMENTS: Association …
