Cupping of the optic nerve head is regarded as one of a triad of diagnostic signs associated with glaucoma. This study was undertaken to assess the role of genetic factors in determining size of the physiologic cup of the normal optic nerve head, as measured by a horizontal cup/disc ratio. This is important to our ultimate understanding of the determinants of pathologic change. Horizontal cup/disc ratio was estimated in a sample of 37 MZ and 26 like-sex DZ twin pairs aged 15 years and older. Differences between MZ and DZ samples with respect to intrapair variance and intraclass correlation coefficient were highly significant. This finding of high heritability for measurements of cup diameter is in contrast to low heritability estimates found in a companion investigation on heritability of the effect of corticosteroids on intraocular pressure.
This paper summarizes research findings from members of the Southwest Medical Sociology Ad Hoc Committee concerning sociocultural barriers to medical care among Mexican Americans in Texas. Committee members individually, or in two-person groups, studied a number of factors concerning Mexican-American medical care in Texas such as: 1) mortality, morbidity, and other health status indicators; 2) health manpower and educational needs; 3) political factors impeding economical health care; 4) alienation, familism, and their relationship to utilization of the health services; 5) language and communication barriers; and 6) folk medicine. Findings include documentation that structural alienation of Mexican-Americans from mainstream Anglo-American middle-class society is carried over into their relation with utilization of the health care delivery system; that their emphasis on familism works alternatively to encourage and discourage their seeking access to health care; the language differences serve to perpetuate certain cultural differences that are inimical to health care delivery; and that curanderismo can be seen as complementing other types of health care. The report concludes with a number of recommendations for accomplishing cultural integration that will lead to better care for this segment of the health population.

The Nurse Career-Pattern Study, conducted by NLN's Division of Research, is a longitudinal study of nurses at 1, 5, 10, and 15 years after graduation from the four types of nursing education programmes. Participants in the study are individuals who entered a sample of associate degree, baccalaureate, diploma and practical nursing programmes in the autumn of 1962; and associate degree, baccalaureate and diploma programmes in the autumn of 1965 and 1967. Each group is followed separately, and the data collection for the four concurrent studies is staggered because of the varying lengths of programmes and times of graduations. According to project director Lucille Knopf, the study is designed to describe the career patterns of participants, their contributions to the health labour force, and the factors influencing their nursing careers.
