Pancreatic Neuroendocrine Neoplasms.

Pancreatic neuroendocrine neoplasms (Pan-NENs) are rare but clinically important lesions. Pan-NENs are known for and often categorized by their capacity to produce clinical syndromes mediated by the production of hormones. Despite sometimes presenting dramatically from excessive hormone production, not all Pan-NENs produce functional hormone, and they can pose diagnostic challenges to practicing pathologists. Distinguishing Pan-NENs from mimics can be crucial, because Pan-NENs carry different prognoses and have unique treatments available due to their specific biological properties. This article reviews the current categorization and features of Pan-NENs.

Caregiver hardiness explored within Watson's theory of human caring in nursing.

Older family caregivers are often responsible for aged parents or spouses. The purpose of this theoretical article is to review the literature regarding the concept of hardiness, present a summary of Jean Watson's Theory of Human Caring in Nursing, explore older caregiver hardiness within Watson's theory, and discuss implications for gerontological nursing. An understanding of older caregiver hardiness within Watson's theory will guide gerontological practice, research, and theory development in nursing.

The subculture of adolescence: beliefs about care, health and individuation within Leininger's theory.

The purpose of this ethnonursing investigation, which was part of a larger study, was to describe and explain the meanings and experiences of adolescents in relation to their care and health within their peer subculture and family contexts. Data were collected using observation-participation and interviews with adolescents in southwestern Ontario, Canada. Interviews were tape recorded, coded and entered on to a computer. The following themes were abstracted from the verbatim descriptors and patterns. (a) Care for adolescents meant "being there' for listening in confidence, helping, gift giving, humour and demonstrating love in time of need. (b) Health for adolescents meant well-being, absence of illness, being fit, dealing with problems, and taking responsibility. (c) The adolescents valued family, friends, education, money, sports, and honesty. (d) Clothes, hair and music were metaphors for adolescents' emerging identities.

The health meanings and practices of older Greek-Canadian widows.

Folk health and illness beliefs and practices were abstracted from a large-scale study of older Greek-Canadian widows conceptualized within Leininger's theory of Cultural Care Diversity and Universality using ethnographic, ethnonursing, and life health-care history methods. Data were collected using observation-participation and interviews in three Greek-Canadian communities with 12 widowed key informants and 30 general informants. Interview inquiry guides, Leininger's Life History Health Care Protocol, and field journal recordings assisted data collection. Data were analysed using Leininger's phases of analysis for qualitative data. A major health theme which was abstracted from the raw data and patterns was: health for Greek-Canadian widows meant a state of well-being, ability to perform daily role activities, and avoidance of pain and illness. The findings, which also included folk health care and illness beliefs and practices, will stimulate future nursing research related to health and nursing care of people of diverse cultures.

Cultural care of older Greek Canadian widows within Leininger's theory of culture care.

Cultural care themes were abstracted from a large scale study of older Greek Canadian widows conceptualized within Leininger's theory of Cultural Care Diversity and Universality. Ethnonursing, ethnographic, and life health-care history methods were used. Data were collected using observation-participation and interviews in three Greek Canadian communities with 12 widowed key informants and 30 general informants. Enabling tools used were interview inquiry guides, Leininger's Life History Health Care Protocol, Leininger's Acculturation Rating and Profile Scale of Traditional and Non-Traditional Lifeways, and field journal recordings. Data were analyzed using Leininger's phases of analysis for qualitative data. The two major cultural care themes which were abstracted from the raw data and patterns were: (1) Cultural care for Greek Canadian widows meant responsibility for, reciprocation, concern, love, companionship, family protection, hospitality, and helping, primarily derived from their kinship, religious, and cultural beliefs, and values, and (2) Cultural care continuity diminished the spousal care void and contributed to the health of Greek Canadian widows. These findings will stimulate future nursing research related to cultural care of diverse populations and guide nursing practice to provide culturally congruent care which will assist widows to reduce their spousal care void. The author thanks Dr. Madeleine Leininger, Dr. Judith Floyd, Dr. Marjorie Isenberg, and Dr. Bernice Kaplan for their guidance in completing the large scale study on which this article is based.

Depression: viewed from a transcultural nursing theoretical perspective.

Phenomena related to depression are discussed transculturally and examined within the context of Leininger's theory of transcultural diversity and universality of care and health. Mental health and mental illness are viewed within the social structure and world view in order to derive culturally congruent nursing care. Recommendations for future research are suggested.

Comparison of two theorists on care: Orem and Leininger.

Dorothea Orem and Madeleine Leininger are two nursing scholars who are contributing significantly to the body of nursing knowledge. This paper contrasts their backgrounds, the origins of their theories, their views of the nature of nursing, use of theory development strategies, and contributions to nursing science. The concepts of Leininger's care and Orem's self-care will be compared as these relate to their theories with the examination of similarities and differences.
