A STUDY OF POSTDIAGNOSIS BREAST CANCER CONCERNS FOR WOMEN LIVING IN RURAL AND REMOTE QUEENSLAND. PART I: PERSONAL CONCERNS

The findings presented in this paper are part of a research project designed to provide a preliminary indication of the support needs of postdiagnosis women with breast cancer in remote and isolated areas in Queensland. This discussion will present data that focuses on the women's expressed personal concerns. For participants in this research a diagnosis of breast cancer involves a confrontation with their own mortality and the possibility of a reduced life span. This is a definite life crisis, creating shock and needing considerable adjustment. Along with these generic issues the participants also articulated significant issues in relation to their experience as women in a rural setting. These concerns centred around worries about how their partner and families cope during their absences for treatment, the additional burden on the family of having to cope with running the property or farm during the participant's absence or illness, added financial strain brought about by the cost of travel for treatment, maintenance of properties during absences, and problems created by time off from properties or self-employment. These findings accord with other reports of health and welfare services for rural Australian and the generic literature on psycho-oncology studies of breast cancer.     

The emergency medicine training needs of rural general practitioners

This study aimed to identify the emergency medicine training needs of rural general practitioners (GPs) in the catchment area of the Hunter Rural Division of General Practice. The GPs were surveyed using a questionnaire in which they were asked about their confidence levels in a number of specific emergency medicine skills, and about the areas of emergency medicine that they saw as priorities for upskilling. More than a third of GPs who were responsible for on-call work at the hospital indicated that they had low levels of confidence in a number of their emergency medicine skills, in particular skills relating to paediatric emergencies, cardiovascular emergencies, and respiratory emergencies. These emergency medicine domains were also seen as high priorities for upskilling by the majority of the respondents. The study shows that rural doctors need the opportunity to access emergency medicine training that provides upskilling not only in the management of clinical problems, but also in practical procedures.     

Metropolitan researchers undertaking rural research: benefits and pitfalls

Can or should metropolitan residents research their rural counterparts and if they do are there inherent pitfalls or benefits? Throughout the history of social and anthropological research there has been debate on the insider–outsider/native–stranger controversy as to who should carry out the field work. This discourse will explore the author’s personal experiences in the context of planning a rural health project, entering the field, accessing the informants, interviewing the informants and leaving the field.     

Poorer nutritional status of the older-generation in a Japanese farming village, as related to fewer types of food consumed

This study was carried out to determine whether the most recent nutritional improvements in Japanese farming villages were due to improvement in the diet of the young only or across all ages. Food duplicates for 24 h were collected. The number of food items and the adequacy of each nutrient level were compared between subgroups, by age of cooking and those eating meals. The older-generation used and ate fewer food items resulting in poorer nutrition. The most recent improvement in nutrition in the farming villages of Japan was found mainly to affect the younger-generation with the older-generations being more poorly nourished.     

Caregiver distress: what nurses in rural settings can do to help

Caregivers in rural settings experience unmet needs. Some family caregivers in rural areas, either willingly or grudgingly, take on the role of caregiving as one of many responsibilities. A review of the literature reveals that the burden of the added responsibility results in physiological and psychological caregiver distress. The authors suggest some strategies to meet caregiver needs and outline areas where research is needed.     

我国农村地区实施大病统筹合作医疗或医疗保险方案的技术缺陷

在我国中等发达及上农村地区,大病统筹合作医疗或医疗保险以其可缓解农村居民的就医经济风险而受到欢迎,但是在方案的拟订过程中尚存在一些明显的技术缺陷,比如,“大病”的技术定义、农村居民就医经济风险分析、风险临界线界定、保险经付比测算和保险费率厘定等,这些技术的缺乏,已严重影响农村合作医疗或医疗保险的推广和实施效果。     

延边农村地区朝鲜族HBV、HCV、HDV感染状况调查

Regional cycles of perfusion and non-perfusion in the lung of the term fetal rabbit.

The spatial distribution of pulmonary blood flow and its change over time was investigated in term fetal rabbits, using the plasma tracer fluorescein-isothiocyanate-labeled bovine serum albumin (FITC-BSA). A tracer bolus was injected intravenously and allowed to circulate in vivo for increasing periods of time (2-30 minutes) prior to arrest of the circulation and tissue preparation. Initially, fluorescence was present in the vasculature of 43% of lung parenchymal tissue, disposed as discrete regions or "lobules." Interspersed regions of lung tissue received no tracer inflow. With increasing tracer circulation times (10, 20, and 30 minutes), a greater percentage of lung cross-sectional area contained vessels exhibiting tracer fluorescence (64, 96, and 100%, respectively). In the fetal lung, a high pulmonary vascular resistance (PVR) is maintained. Our studies indicate that, at any given moment, fetal pulmonary blood flow is distributed only to a proportion of discrete lung "lobules," while interspersed "lobules" receive no flow at all. The "lobules" alternate between these "high" and "low" vascular resistance states with a periodicity of approximately 35 minutes, comprising 22 minutes of non-perfusion followed by 13 minutes of perfusion. This circulatory pattern permits both the maintenance of high PVR and uniform lung development. Further, by directing flow to only a portion of the vasculature, greater microvascular flow rates are achieved and hence the risk of blood sludging and stasis is reduced. Recruitment of these "non-perfused" regions at birth could thus produce a significant reduction in PVR.     

pD2-, pA2- and pD2'-values of a series of compounds in a histaminic and a cholinergic system.

(1) Affinity and intrinsic activity values of 75 compounds for a histaminergic and a cholinergic system are presented. The quantitative correlations between the affinity values of 35 compounds and some physicochemical constants (Van der Waals volume, lipophilicity, number of hydrogen atoms on the protonated amine) are discussed. (2) Absence of systematic differences between pD2 and pA2 of partial agonists supports the assumption that these values are equivalent expressions of the same affinity. (3) The "mimetic moiety" in a number of the antihistaminic test compounds hardly contributes to their affinity. The affinity mainly depends on an interaction tendency with additional receptor areas. (4) The correlation between pA2 and pD2' of the whole series of compounds in the histaminergic system is artificial. The method only allows determination of both values if their ratio lies between certain limits. (5) The correlation between pA2 and pD2' for 16 closely related compounds in the guinea pig ileum and for nearly all compounds in the rat intestine has to be explained by an influence of the structural differences on drug transference and/or the less specific binding forces. (6) The metactoid receptors in the two systems are different structures. (7) Possible molecular modifications to maximize the separation of antihistaminic form cholinergic affinity are suggested.     

Importance of uniform heparin coating on biopolymers

Cardiopulmonary surgeries need connectors for extracorporeal circulation. The patient's blood in contact with the tube surfaces modifies its plasmatic proteins, promotes platelet aggregation, and activates the complement system, unleashing thrombus formation. Thus, it becomes necessary for an anticoagulant to keep the circuit free from these events. Heparin is the anticoagulant used even after reports about its disadvantages. Platelet adherence seems to be very dependent on the quality from the surfaces that can promote cellular proliferation, aggregation, and thrombosis. In this study, we compare the quality of the heparin-coated and uncoated surfaces. We used a blood cell culture and scanning electron microscopy (SEM) to visualize the platelet aggregation. It was concluded that there are groove areas that permit platelet adherence, and if they are not coated totally by the heparin, aggregation still occurs although in lower scale than on the uncoated tubes.
