Stem Cell Matching For Patients Of Mixed Race, Ted C. Bergstrom Dec 2009

Stem Cell Matching For Patients Of Mixed Race, Ted C. Bergstrom

Ted C Bergstrom

Patients with leukemia and other blood diseases stand a good chance of recovery and a return to normal life if they receive a stem cell transplant from a living donor. In the absence of a transplant, their survival prospects are grim. For a transplant to be successful, the human leukocyte antigens (HLA) of the donor and recipient must be a close genetic match. To facilitate non-sibling matches, the developed nations of the world have set up national volunteer registries. The larges such registry is the NMDP (National Marrow Donor Program). We estimate the distribution of HLA types for individuals of …

Emerging health problems require rapid advice. We describe the development and pilot testing of a systematic, transparent approach used by the World Health Organization (WHO) to develop rapid advice guidelines in response to requests from member states confronted with uncertainty about the pharmacological management of avian influenza A (H5N1) virus infection. We first searched for systematic reviews of randomized trials of treatment and prevention of seasonal influenza and for nontrial evidence on H5N1 infection, including case reports and animal and in vitro studies. A panel of clinical experts, clinicians with experience in treating patients with H5N1, influenza researchers, and methodologists …


Whose Duty Is It Anyway?: The Kennedy Krieger Opinion And Its Implications For Public Health Research, Diane E. Hoffmann, Karen H. Rothenberg Dec 2009

Whose Duty Is It Anyway?: The Kennedy Krieger Opinion And Its Implications For Public Health Research, Diane E. Hoffmann, Karen H. Rothenberg

Karen H. Rothenberg

In this article, the authors discuss the Maryland Court of Appeals decision in the case of Grimes v. Kennedy Krieger Institute, Inc. and its implications for the tort duty owed by researchers, in particular public health researchers, to their subjects. The Opinion resulted from two lawsuits alleging lead poisoning of children enrolled in a study conducted by the Kennedy Krieger Institute, a world renown pediatric research and treatment facility. The opinion shocked the research establishment with its scathing characterization of researchers and its apparent holding that in Maryland a parent cannot consent to the participation of a child in "nontherapeutic …

Bisphenol-A And The Great Divide: A Review Of Controversies In The Field Of Endocrine Disruption, Laura Vandenberg, Maricel V. Maffini, Carlos Sonnenschein, Beverly S. Rubin, Ana M. Soto Dec 2009

Bisphenol-A And The Great Divide: A Review Of Controversies In The Field Of Endocrine Disruption, Laura Vandenberg, Maricel V. Maffini, Carlos Sonnenschein, Beverly S. Rubin, Ana M. Soto

Laura Vandenberg

In 1991, a group of 21 scientists gathered at the Wingspread Conference Center to discuss evidence of developmental alterations observed in wildlife populations after chemical exposures. There, the term “endocrine disruptor” was agreed upon to describe a class of chemicals including those that act as agonists and antagonists of the estrogen receptors (ERs), androgen receptor, thyroid hormone receptor, and others. This definition has since evolved, and the field has grown to encompass hundreds of chemicals. Despite significant advances in the study of endocrine disruptors, several controversies have sprung up and continue, including the debate over the existence of nonmonotonic dose …

Lorelei Lingard

Communication among healthcare professionals is a focus for research and policy interventions designed to improve patient safety, but the challenges of changing interprofessional communication patterns are rarely described. We present an analysis of 756 preoperative briefings conducted by general surgery teams (anesthesiologists, nurses, and surgeons) at four urban Canadian hospitals in the context of two research studies conducted between August 2004 and December 2007. We ask the questions: how and why did briefings succeed, how and why did they fail, and what did they mean for different participants? Ethnographic fieldnotes documenting the coordination and performance of team briefings were analyzed …

Edward Yu

Post-operative radiation therapy (RT) (1) and post-operative chemoradiation (2) have been used for esophageal cancer patients deemed high risk for recurrence after esophagectomy. Defining opitmal RT target volume after esophagectomy is difficult due to significant changes in patient anatomy and function. Some radiationon cologists advocated the inclusion of the anastomotic site within the irradiation volume due to concerns for potential increased relapse risk, while others did not subscribe to this practice due to concerns for increased treatment related toxicity. We have previously reported patient outcome benefit using extended volume RT In management with high risk esophageal cancer patients underwent esopagectomy(3). …

OBJECTIVE: To assess the impact of extended field irradiation with anastomotic coverage on local recurrence in high risk resected esophageal cancerpatients. METHODS: From 1989-1999, high risk resected esophageal cancer cases receiving post-resection chemoradiation were reviewed. Adjuvant chemotherapy consisted of four cycles of fluorouracil-based regimens. Loco-regional irradiation with or without coverage of anastomotic site had radiation a dose range from 45-60 Gyat 1.8-2.0 Gy/fraction given with initial anterior-posterior/posterior-anterior arrangement with either extended (with anastomotic coverage), or small (without anastomotic coverage) field followed by oblique fields for boost. RESULTS: One hundred eighty-eight charts were reviewed. Seventy-two patients were eligible for post-resection chemoradiation. …

Shamara M Baidoobonso, PhD

The Challenge: Most studies of HIV and health in African, Caribbean and Black (ACB) communities have taken place in large urban centres and rarely examine how the interactions between racism, gender, HIV-related stigma and multiple forms of oppression affect health and HIV vulnerability. This lack of information negatively impacts HIV prevention and health promotion efforts for ACB communities. Our Approach: The BLACCH Study uses a community-based approach to collect extensive information about the health of ACB communities in Middlesex County, Ontario. The first stage of the project consists of semi-structured interviews to collect information about the breadth of health-related experiences …

John Contracts Skin Disease At Spa, Donna M. Hughes Dr., Melanie Shapiro Esq

Donna M. Hughes

A virus that causes a skin disease called Molluscum contagiosum is being spread at a spa-brothel in Providence. Molluscum contagiosum is a skin disease caused by a virus. The infection causes small white, pink, or flesh-colored bumps or growths on areas which came in contact with the infected skin of another person. Molluscum contagiosum can be treated or will disappear on its own, although it takes time. According to the Center for Disease Control “the bumps disappear on their own within 6 months. However, they may not go away completely for up to 4 years.” The person can infect another …

Edward Yu

Management of patients who have disease relapse after completion of surgery and adjuvant chemo-radiation (CRT) is controversial. Some oncologists would advocate intensive therapeutic intervention due to promising experience on treatment for recurrence disease while others would recommend palliative support due to the concerns for poor patient outcome post disease recurrence. In Addition, it is not clear if patient outcome is improved post adjuvant CRT when patients at risk have resection margin involvement and if time interval to recurrence can affect patient survival post relapse. The present study was conducted to determine what factors will affect patient outcome at relapse after …

One Chance In A Million: Altruism And The Bone Marrow Registry, Ted Bergstrom, Rod Garratt, Damien Sheehan-Connor

Ted C Bergstrom

Transplants of donated stem cells save the lives of many patients with blood diseases. Donation is somewhat painful, butrarely has lasting adverse effects. Patients can accept transplants only from donors with compatible immune systems. Those lacking a sibling match must seek donations from the population at large. The probability that two persons of the same race are compatible is less than 1/10,000. Health authorities maintain a registry of several million genetically-tested potential donors who have agreed to donate if asked. We study the peculiar structure of voluntary public good provision represented by the registry, and compare the marginal benefits and …

Influence Of Prenatal Lead Exposure On Genomic Methylation Of Cord Blood Dna, Richard J. Pilsner, Howard Hu, Adrienne Ettinger, Brisa N. Sánchez, Robert O. Wright, David Cantonwine, Alicia Lazarus, Héctor Lamadrid-Figueroa, Adriana Mercado-García, Martha Maria Téllez-Rojo, Mauricio Hernández-Avila

J. Richard Pilsner

Background

Fetal lead exposure is associated with adverse pregnancy outcomes and developmental and cognitive deficits; however, the mechanism(s) by which lead-induced toxicity occurs remains unknown. Epigenetic fetal programming via DNA methylation may provide a pathway by which environmental lead exposure can influence disease susceptibility.

Objective

This study was designed to determine whether prenatal lead exposure is associated with alterations in genomic methylation of leukocyte DNA levels from umbilical cord samples.

Methods

We measured genomic DNA methylation, as assessed by Alu and LINE-1 (long interspersed nuclear element-1) methylation via pyrosequencing, on 103 umbilical cord blood samples from the biorepository of the …
