Roles of physicians, genetic counselors, and nurses in the genetic counseling process.

A self-administered questionnaire was mailed to 325 genetic counseling professionals in the southeastern United States and 204 (63%) completed it. Among those responding, 32% held master's degrees in genetic counseling, 30% M.D. degrees, 23% degrees in nursing, and 3% master's degrees in social work. While genetic counseling typically involves team effort, members were generally unclear regarding their roles in the process. Respondents rarely referred their clients to social workers but believe they should. Most did not believe that master's trained genetic counselors should be the only health professional who provide counseling. The respondents strongly supported goals that dealt with the educative aspect of counseling and protection of patient autonomy.

The Genetic Counseling Video Project (GCVP): models of practice.

Genetic counseling is conceptualized as having both "teaching" and "counseling" functions; however, little is known about how these functions are articulated in routine practice. This study addresses the question by documenting, on videotape, the practices of a national sample of prenatal and cancer genetic counselors (GCs) providing routine pre-test counseling to simulated clients (SCs). One hundred and seventy-seven GCs recruited at two annual conferences of the National Society of Genetic Counselors (NSGC) were randomly assigned to counsel one of six female SCs of varying ethnicity, with or without a spouse, in their specialty. One hundred and fifty-two videotapes were coded with the Roter Interaction Analysis System (RIAS) and both GCs and SCs completed evaluative questionnaires. Two teaching and two counseling patterns of practice emerged from cluster analysis. The teaching patterns included: (1) clinical teaching (31%) characterized by low psychosocial, emotional and facilitative talk, high levels of clinical exchange, and high verbal dominance; and (2) psycho-educational teaching (27%) characterized by high levels of both clinical and psychosocial exchange, low levels of emotional and facilitative talk, and higher verbal dominance. The counseling patterns included: (1) supportive counseling (33%) characterized by low psychosocial and clinical exchange, high levels of emotional and facilitative talk, and low verbal dominance; and (2) psychosocial counseling (9%) with high emotional and facilitative talk, low clinical and high psychosocial exchange, and the lowest verbal dominance. SCs ratings of satisfaction with communication, the counselor's affective demeanor, and the counselor's use of non-verbal skills were highest for the counseling model sessions. Both the teaching and counseling models seem to be represented in routine practice and predict variation in client satisfaction, affective demeanor, and nonverbal effectiveness.

Transduction of endogenous envelope genes by feline leukaemia virus in vitro.

Feline leukaemia viruses (FeLV) are exogenous retroviruses that can be detected in most cats with leukaemia, aplastic anaemia, myeloproliferative diseases and fatal immunosuppression. FeLV isolates have been divided into three subgroups, based on the viral envelope-determined properties of interference and host range in vitro. FeLV-A is present in all natural isolates and is generally minimally pathogenic. FeLV-B is found with FeLV-A in isolates from approximately 40% of natural infections and in a higher percentage of cats with lymphoma. Following the fundamental observations of genetic reassortment of avian retroviruses with endogenous viral genes and the origination of lymphomagenic viruses during the ontogeny of AKR mice, we show here that transfection of feline cells with FeLV-A DNA results in its recombination with endogenous FeLV-related sequences to produce viruses with the structural and host range properties of FeLV-B. Thus in vitro propagation of a retrovirus may result in the generation of variants with very different properties.

NICHD research initiative in newborn screening.

Recent changes in genetics research have created new opportunities to improve the scope and quality of newborn screening services. Changes in newborn screening should be supported and directed by an organized program of research. The NICHD Research Initiative in Newborn Screening includes the development of systematic methods to identify additional conditions appropriate for newborn screening; development and testing innovative interventions and treatments to improve outcomes; education of the provider workforce; development and implementation of appropriate information and communication systems for parents and providers; and, sponsoring an ongoing program of research and research training. Future needs will include the development of a national translational research infrastructure, prevention research and research into behavioral and social sciences issues. The NICHD Research Initiative in Newborn Screening is expected to be an ongoing and vital initiative that adapts itself to new scientific findings, technological developments, changes in the public and personal health care system, and our evolving understanding of the needs of affected individuals, families and the community.

[Prevention of mental retardation: knowledge and perception by health professionals].

This article aimed to evaluate the prevention of mental disability in primary healthcare services in Maringá, Paraná, Brazil. The sample consisted of 90 male and female physicians from different fields, namely gynecology and obstetrics, pediatrics, general practice, and family health, as well as 66 male and female nurses. A multiple-choice questionnaire was filled out by the subjects themselves from August to December 2003. Qualitative variables were compared using the chi-square test at 5% significance level. Partial data relating to both the perception and knowledge of health professionals concerning mental disability were as follows: 75% were unable to choose the correct alternative on prevalence; 25% did not know how the genome contributes to etiology; 37% were unaware of prevention for mental disability; 28% were not confident in providing orientation on the teratogenic effect of ethanol; 35% demonstrated insecurity in orienting patients on amniocentesis. The data showed that participants had an unsatisfactory perception of the relevance of mental disability within the overall population disease profile, and that they need more information on the respective genetic and environmental issues.

The promise of molecular epidemiology in defining the association between radiation and cancer.

Molecular epidemiology involves the inclusion in epidemiologic studies of biologic measurements made at a genetic and molecular level and aims to improve the current knowledge of disease etiology and risk. One of the goals of molecular epidemiology studies of cancer is to determine the role of environmental and genetic factors in initiation and progression of malignancies and to use this knowledge to develop preventive strategies. This approach promises extraordinary opportunities for revolutionizing the practice of medicine and reducing risk. However, this will be accompanied by the need to address and resolve many challenges, such as ensuring the appropriate interpretation of molecular testing and resolving associated ethical, legal, and social issues. Traditional epidemiologic approaches determined that exposure to ionizing radiation poses significantly increased risk of leukemia and several other types of cancer. Such studies provided the basis for setting exposure standards to protect the public and the workforce from potentially adverse effects of ionizing radiation. These standards were set by using modeling approaches to extrapolate from the biological effects observed in high-dose radiation studies to predicted, but mostly unmeasurable, effects at low radiation doses. It is anticipated that the addition of the molecular parameters to the population-based studies will help identify the genes and pathways characteristic of cancers due to radiation exposure of individuals, as well as identify susceptible or resistant subpopulations. In turn, the information about the molecular mechanisms should aid to improve risk assessment. While studies on radiogenic cancers are currently limited to only a few candidate genes, the exponential growth of scientific knowledge and technology promises expansion of knowledge about identity of participating genes and pathways in the future. This article is meant to provide an introductory overview of recent advances in understanding of carcinogenesis at the molecular level, with an emphasis of the aspects that may be of use in establishing the association between radiation and cancer.

Nephrology in South East Asia: fact and concept.

The developing countries of South East Asia lie within the tropics. Renal disease in this region represents the interaction between the kidney and the environment abetted by low levels of socioeconomic development in many areas. Together with genetic susceptibility to some diseases, there are widespread infectious diseases and prominently encountered plant and animal toxins. Chronic renal failure, most commonly the outcome of chronic glomerulonephritis and frequently to persistent nephrolithiasis as well as acute renal failure due to a variety of stimuli, are among the most common renal problems encountered. Renal replacement therapy is both a clinical and economic problem. The epidemiology of renal disease in the region is poorly understood, and workforce and treatment facilities are not adequate for the caseload in a number of countries in the region. Many people with chronic renal disease simply cannot afford the necessary treatment. The principle focus for the future must be on prevention strategies and the provision of appropriate health services within the current economic and technological restraints.

Nonresponsiveness to hepatitis B vaccine in health care workers. Results of revaccination and genetic typings.

Twenty-eight health care workers who had a poor antibody response when initially vaccinated with hepatitis B vaccine were revaccinated with three additional 20-microgram doses. Eight of the twenty nonresponders, who had levels of antibody to hepatitis B surface antigen (anti-HBs) of less than 8 estimated radioimmunoassay (RIA) units, and all 8 of the hyporesponders, who had anti-HBs levels of 8 or 16 RIA units, attained anti-HBs levels of 36 RIA units or more after revaccination. Tests for HLA-A, B, C, and DR; for complement proteins C2, C4A, C4B, and BF; and for the erythrocyte enzyme glyoxalase I were done in 17 nonresponders and 3 hyporesponders. Nine (45%) had HLA-DR7 and 8 (40%) had HLA-DR3, compared with an expected rate of 23% in the general population. At least one of two extended haplotypes (B44, DR7, FC31 or B8, DR3, SCO1) were detected in 6 of the 9 who did not respond to revaccination, compared with 2 of 11 who responded to a second course of vaccine. Poor responders to vaccine may benefit from revaccination, and genetic factors may modulate the immune response to vaccination.

Malaria: nutritional implications.

Epidemiologic and immunologic factors determine the impact of malaria on the demography and economics of human communities. Where malaria is epidemiologically stable, its effects are most obvious in young children; adults, because of acquired immunity, are much less affected and remain an economically viable workforce. Where the disease is unstable, it affects all age groups and may incapacitate adults enough to impede food production seriously. Three areas are identified in which malaria may adversely affect host nutrition: low birth weight, the development of protein energy malnutrition, and the pathogenesis of anemia. The influence of host nutrition on malarial infections is considered. The view is expressed that, although deficiencies of some dietary factors may potentiate the resistance to malaria conferred by some genetic traits, there is as yet little convincing evidence that malnutritional states in humans materially enhance the severity or lethality of plasmodial infections.

A short history of pediatric endocrinology in North America.

Pediatric endocrinology evolved as a subspecialty from the era of biochemical and metabolic clinical investigation led by John Howland, Edwards Park, and James Gamble at Johns Hopkins; Allan Butler at Boston University and Harvard University; Daniel Darrow at Yale University; and Irving McQuarrie at the University of Rochester and the University of Minnesota during the early 20th century. The father of the new subspecialty was Lawson Wilkins, a private pediatric practitioner in Baltimore, Maryland, who was invited by Dr. Edwards Park to establish an endocrine clinic at the Harriet Lane Home at Johns Hopkins in 1935. Dr. Wilkins managed his practice and the clinic until 1946, when, at the age of 52, he accepted a full-time position at the University. Dr. Nathan Talbot was invited to develop a pediatric endocrine clinic at Massachusetts General Hospital by Allan Butler in 1942. These units and their associated subspecialty training programs during the 1950s and 1960s provided the large majority of the second-generation pediatric endocrinologists who went on to establish endocrine subspecialty programs in university medical centers in North America as well as Europe and South America. Diabetes as a clinical pediatric discipline evolved in parallel from the early clinics of Elliott Joslin and Priscilla White in Boston, M.C. Hardin and Robert Jackson at the University of Iowa, George Guest at the University of Cincinnati Children's Hospital, and Alex Hartman at the St. Louis Children's Hospital. The Lawson Wilkins Pediatric Endocrine Society was founded in 1971, and the Council on Diabetes and Youth was established within the American Diabetes Association in 1980. Medical and economic factors led to increasing integration of pediatric diabetes and general endocrine care and training, and diabetes care now is a major activity within the subspecialty of pediatric endocrinology. The growth of pediatric endocrinology in North America has paralleled the growth of academic medicine during the past half-century. In 2002, there were 72 training programs in North America: 65 in the United States and seven in Canada. The endocrinology sub-board of the American Board of Pediatrics was established in 1978 to certify training and competence in endocrinology, including diabetes. By 2002, the board had certified 927 pediatric endocrinologists. Pediatric endocrine subspecialists during the past half-century have contributed major advances in our understanding of the ontogeny of endocrine systems and the diagnosis and treatment of fetal-perinatal endocrine disorders; newborn screening for endocrine and metabolic disorders; the physiology and therapies for disorders of sexual differentiation and pubertal maturation; the development of anthropometric standards for childhood growth and development; the characterization and physiology of hormone systems, including receptors and hormone actions; the molecular genetics of a number of congenital endocrine disorders and heritable endocrine diseases; development of pediatric endocrine diagnostics and reference standards; the pathophysiology and management of autoimmune endocrine disease; and development of a growing armamentarium of therapeutic agents for treatment of endocrine and metabolic diseases.
