Anthropology, nursing and midwifery: a natural alliance?

Anthropology, and its supposed operationalisation within transcultural nursing, is becoming increasingly prominent in educational curricula in the U.K. This increase in interest is driven both by governmental pressure to provide more culturally appropriate care, and an intuitive notion that anthropology, nursing and other related professions such as midwifery have a common basis of mutually overlapping and re-enforcing theory and practice. This paper explores the question of whether there is a natural alliance between anthropology, and the applied aspects of health care disciplines such as nursing and midwifery, by examining some of the concepts underlying each discipline, and the ways in which these concepts are applied in practice. Anthropology is the study of culture, and it is suggested that a more complete understanding of this central concept is essential if it is to be utilised in the applied disciplines encompassed by the practice of nursing and midwifery.     

Intravenous or rectal administration of sedatives in outpatient oral surgery

A number of cross-over studies on sedation in outpatient oral surgery investigated the quality of sedation produced by intravenous or rectal administration of diazepam. The sedation methods were equally efficient with a mean dose of 0.24 mg/kg (range 0.1–0.4) for i.v. administration and 0.53 mg/kg (range 0.5–0.6) for rectal administration. Eighty-five percent of the patients preferred surgery under sedation and local anaesthesia to local anaesthesia alone. The patients preferred the session in which they experienced stronger sedation, regardless of the route of administration.     

In VivoStudies of Adenovirus-Based p53 Gene Therapy for Ovarian Cancer

Objectives.To test the safety, efficacy, and toxicity of gene therapy using wild-type p53-expressing adenovirus (Ad-CMV-p53) in a nude mouse model with intraperitoneal (ip) 2774 human ovarian cancer cell line that contains a p53 mutation.Study design.An initial study of adenovirus tolerance was determined in nude mice by a single ip injection of increasing doses of Ad-CMV-p53. Nude mice were implanted with an LD₁₀₀dose of 1 × 10⁷cells. To study the efficacy and specificity of Ad-CMV-p53 treatment, the mice received treatment with different adenovirus constructs. One group received Ad-CMV-p53 and another group received a control adenovirus construct, Ad-CMV-βgal. To study the treatment response to Ad-CMV-p53, the mice were divided into groups and received various treatment schedules of 1 × 10⁸pfu of Ad-CMV-p53.Results.The mice tolerated Ad-CMV-p53 without adverse effects at doses of 1 × 10⁸pfu. The response to Ad-CMV-p53 showed significant survival duration in each dose regimen, with a survival time greater than that of untreated animals (P= 0.0173). However, no statistically significant survival advantage was observed between Ad-CMV-p53- and Ad-CMV-βgal-treated mice.Conclusions.These studies show that at the adenovirus dose and administration regimen used, there is effective but not specific 2774 tumor growth inhibitionin vivo.Efficient introduction of biologically active genes into tumor cells would greatly facilitate cancer therapy. Thus, although promising, these results caution that much effort will be required to realize the potential for clinical application of adenovirus-based ovarian cancer gene therapy.     

Systemic and peritoneal host defense in peritonitis

Most of the work of host defense has been carried out in mixed patient populations. It is now clear that elective preoperative surgical patients have totally different host defense capabilities as compared to posttrauma patients or those suffering from peritonitis. Specific cell-mediated immune studies need to be repeated in these 2 patient groups as well. What will contribute clinical relevance to these studies will be the means to correct the defects. If these defects or—more correctly termed—abnormalities of host defense are, indeed, important and contribute to an increased sepsis rate and mortality from sepsis in affected patients, then correcting them should reduce these complications. This hypothesis can only be tested when such means become available. The issues of most interest in the next few years will be the significance of serum albumin in host outcome, the role of immunomodulators, the involvement of cytokines in the overall process of host defense, and the use of specific nutritional support regimens targeted to the immune system.

Resumen La mayor parte del trabajo sobre los mecanismos de defensa del huésped ha sido realizada en poblaciones mixtas de pacientes. Actualmente aparece claro que los pacientes preoperatorios electivos poseen una capacidad de defensa de huésped totalmente diferente que la de los pacientes en estado posttrauma o de aquellos con peritonitis. Aparece necesario realizar estudios específicos de inmunidad celular en estos 2 grupos de pacientes; aquello que aporte pertinencia clínica en tales estudios habrá de representar medios para corregir estos defectos. Si tales defectos, mejor denominados anormalidades en las defensas del huésped, son de verdad importantes y contribuyen a mayores tasas de infección y de mortalidad por sepsis en los pacientes afectados, su corrección debe resultar en reducción de estas complicaciones. Esta hipótesis sólo puede ser puesta a prueba cuando tales medios se hallen disponibles. Los aspectos de mayor interés en los próximos años serán el significado de la albúmina sérica en la evolución final del huésped, el papel de los inmunomoduladores, la participación de las citocinas en el proceso general de defensa del huésped, y el uso de regimenes especificos de soporte nutricional dirigidos hacia el sistema inmune.

Résumé La plupart des travaux sur les mécanismes de défense ont été faits sur les populations mixtes. Il est à présent certain que les patients opérés électivement ont des mécanismes de défense préopératoire totalement différents de ceux des traumatisés ou des patients ayant une infection péritonéale. Les études immunologiques sur la médiation cellulaire spécifique méritent d'être refaites chez ces deux populations. Ce qui ressortira de ces études donnera les moyens de corriger les défauts ou plutôt les anomalies des mécanismes de défense qui contribuent à augmenter septicité et mortalité en rapport avec l'état septique. Cette hypothèse ne peut être vérifiée qu'avec ces moyens. Les questions les plus intéressantes dans les années à venir sera peut-être de connaître l'influence de l'albumine sérique sur l'évolution, le rôle des immunomodulaterus, celui des cytokinines dans le procédé global des mécanismes de défense, et celui de l'utilisation de l'alimentation spécifique pour améliorer le système immune.

Sexual fantasies of heterosexual and homosexual men

Heterosexual men and homosexual men rated how arousing different sexual fantasies were and how often they had used these fantasies over the previous year. Within each group, sensual and genital same-orientation fantasies were more arousing than either public-sex or dominance-submissive fantasies, which in turn were more arousing than aggressive-sex fantasies. For both heterosexual and homosexual men the extent to which a fantasy was arousing correlated with the person's experience of the activity depicted in the fantasy. The frequency of use of a fantasy correlated positively with its arousal level but not always subtantially so. The results are discussed in the context of the mediating role of fantasy in human sexual arousal.     

Measuring Occupational Health Nurses'' Counseling on Health Promotion

Abstract The purpose of the study was to validate an instrument that measures health counseling practices of occupational health nurses. The measure, the health habits counseling questionnaire (HHCQ), was derived from a model of physician counseling practices. The health habits included smoking, alcohol, weight management, and exercise. Safety at work was added for this random sample of California occupational health nurses. Reliability was comparable to original findings for a random sample of physicians drawn from the roster of a western medical society. The validity of the hypothesized global constructs of aggressiveness and indications was not supported. Physicians in the normative sample were more likely to use primary prevention as an indication for counseling. Overall, occupational health nurses and medical society physician members were similar on many aspects of their counseling, although some significant differences did exist.
