Origin of bilaterian body plans: evolution of developmental regulatory mechanisms.

An argument is proposed to explain the origin of large metazoans, based on the regulatory processes that underlie the morphogenetic organization of pattern in modern animals. Genetic regulatory systems similar to those used in modern, indirectly developing marine invertebrates are considered to indicate the Precambrian regulatory platform on which were erected innovations that underlie the development of macroscopic body plans. Those systems are genetic regulatory programs that produce groups of unspecified "set-aside cells" and hierarchical regulatory programs that initially define regions of morphogenetic space in terms of domains of transcription factor expression. These ideas affect interpretation of the development of arthropods and chordates as well as interpretation of the role of the genes of the homeotic complex in embryogenesis.

Hypertrophic cardiomyopathy: medical, surgical, and nursing management.

Hypertrophic cardiomyopathy (HCM) has been intriguing health care professionals for years. It is a disease of the cardiac muscle characterized by hypertrophy with or without left ventricular outflow tract obstruction. It affects people of all ages and is commonly associated with sudden death. The clinical presentation and treatment of HCM varies widely with the individual and therefore offers the cardiovascular nurse a unique challenge. This article assists the nurse in providing care to these patients by reviewing the cause and prognosis, pathophysiology, clinical manifestations, surgical and medical therapy, and the nursing care following surgical intervention for HCM.

Social workers' knowledge about AIDS: working with vulnerable and oppressed people.

This study assessed social workers' differential knowledge about human immunodeficiency virus (HIV) infection. A questionnaire was mailed to a random sample of 500 members of the National Association of Social Workers in July 1988. Results show that social workers have the most information regarding transmission of HIV infection and the least information about the effects of HIV on specific subpopulations. Of particular concern was that respondents who stated they had either a personal or professional reason for being knowledgeable about acquired immune deficiency syndrome were no more informed about minority issues than those who did not think they had a personal or professional reason for being knowledgeable.

Social workers' knowledge about AIDS: a national survey.

A study was conducted to assess social workers' knowledge about human immunodeficiency virus (HIV) infection. A questionnaire was mailed to a random sample of 500 members of the National Association of Social Workers in July 1988. Three hundred seventy-nine (75.8 percent) members responded, and limited demographic comparisons indicated that the sample was representative of the association's membership. Results showed that social workers have much to learn about acquired immune deficiency syndrome (AIDS); less than half the questions were answered correctly. Respondents had the most information about transmission of the virus and the least information about the impact of the epidemic on specific populations. Of particular concern was the small number of respondents who reported that they had professional reasons for being knowledgeable about AIDS, given the pervasive nature of the AIDS epidemic and every social worker's professional responsibility to be knowledgeable about HIV infection.

Extracorporeal membrane oxygenation in adults: a nursing challenge.

ECMO is an aggressive treatment for selected patients who are unresponsive to conventional therapy for respiratory failure. Although its use in neonates is well documented, the number of successful reports in adults is limited. Venovenous ECMO represents a therapeutic option for adult patients with severe respiratory failure that has not responded to diuresis, high oxygen flows, and positive end-expiratory pressure. As medical centers obtain more experience with and resources for adult ECMO, critical care nurses will need to develop more familiarity with this technology.

Changing needs of patients and families in the acute care hospital: implications for social work practice.

Much attention has been given in recent years to changing reimbursement for hospital care, shortened lengths of stay, and changes in the delivery of health care. The corollaries to these changes are more restrictive admission criteria, increased severity of patient illness, and changes in patient care. The purpose of the present paper is to describe the inpatients who remain in the acute care hospital, and to examine both how the patients and families in need of social work consultation are identified and the implications of these methods of identification for social work practice.

Changing needs of patients and families in long-term care facilities: implications for social work practice.

The purpose of this paper is to describe the changing needs of patients in long-term care facilities and their families. The argument will be made that the characteristics of residents have changed significantly with implementation of prospective payment for hospital care of Medicare patients. In addition to the traditional nursing home resident, staff will be expected to respond to the needs of patients who are both more acutely ill and responsive to aggressive rehabilitative efforts as well as to patients who are more critically ill and near death. The implications of these changes for the social work staff of long-term care facilities will be discussed.

Depression and anxiety in cancer patients: evidence for different causes.

Fifty-seven cancer patients currently receiving treatment were classified into three groups: (1) those who stated they were depressed/anxious for reasons other than cancer at any time in the past, including the interview day, (2) those who stated they were depressed/anxious solely related to cancer during the past or currently, (3) those who stated they were not depressed/anxious at anytime either in the past or currently, or had only 'normal' symptoms. Patients who were depressed for reasons other than cancer scored higher on self-rated anxiety, depression, and somatization. Patients who were depressed solely due to cancer were not significantly different from those with 'normal' symptoms. The findings suggest the importance of adequate differential diagnosis. The use of anti-depressant treatment with a subset of depressed cancer patients is also suggested.

Psychosocial adjustment of the family caregiver: home hemodialysis as an example.

Chronic renal failure is an example of chronic illness where the family is often expected to provide ongoing home health care. This paper reports the results of a study with 19 women who were trained to assist their husbands with home hemodialysis. The impact of living with a spouse with chronic renal failure is discussed, using case examples. Future research needs are addressed.

Integration of medical and psychosocial needs of the home hemodialysis patient: implications for the nephrology social worker.

Good patient management of the medical and technical aspects of home hemodialysis may be inversely related to positive psychosocial adjustment to chronic renal failure. The following article explores the interaction between the patient's medical and psychosocial adjustment to home hemodialysis and suggests how the nephrology social worker might help enhance patient adjustment by working at the interface of the various disciplines on the nephrology team, and at the interface between the patient and the team members.

Evaluation of social work practice in health care settings.

The purpose of this article is to encourage social workers in health care settings to evaluate the effectiveness of their practice. Recent studies of intervention outcome in health care settings are reviewed on four dimensions. Because most of these utilize large group designs and social workers in direct practice rarely conduct this type of research, single-system designs are proposed as a complementary and feasible approach to evaluation. Issues in the use of single-system designs within health care settings and a case example will be discussed.

Bovine anaplasmosis transmission studies conducted under controlled natural exposure in a Dermacentor andersoni = (venustus) indigenous area of eastern Oregon.

In Anaplasma marginale transmission studies conducted on the high semi-arid range of eastern Oregon during the 1974 and 1975 vector season, A marginale-susceptible calves (principals) were maintained on 2 raised tick-proof platforms. Anaplasmosis-susceptible control calves of approximately the same age and latent-infected cows grazed the area surrounding the platforms. One latent-infected steer spent the entire 1975 vector season on a platform with the principals. The 28 principals did not develop anaplasmosis, whereas 15 of 30 (50%) controls became infected. The disease was not transmitted from the latent-infected cattle to the principals exposed only to flying hematophagous insects, whereas 50% of the controls exposed to the Rocky Mountain wood tick Dermacentor andersoni) = (venustus) developed the disease. Dermacentor andersoni appears to be the principal vector on this range.

Absence of Anaplasma marginale infection in American Bison raised in an anaplasmosis endemic area.

Blood was collected at slaughter from 132 adult American bison (Bison bison) raised in an anaplasmosis endemic area where the vector Dermacentor andersoni (equals venustus) is indigenous. Hematologic studies revealed no indication of clinical anaplasmosis. Card agglutination and complement-fixation tests on all bison serums were negative. Eleven anaplasmosis-susceptible calves each inoculated with 204 ml of blood pooled from 12 bison did not develop anaplasmosis. Results of this study indicate American bison have resistance to natural A. marginale infection.
