Dyadic social-support for cardiac surgery patients--a Canadian approach.

Over the past 15 years there has been a substantial increase in the number of cardiac operations being performed. The role of the lay helper volunteer who has successfully recovered from cardiac surgery, offering support to individuals about to undergo similar surgery, is earning a legitimate place in cardiac rehabilitation. This 'living proof' model of support appears to have a significant buffering effect through increasing the cardiac patients' readiness for cardiac surgery and motivation for cardiac rehabilitation. Most literature focuses on individuals who have suffered a myocardial infarction rather than those who must undergo cardiac surgery. The focus of this article is lay volunteer dyadic social-support for open-heart surgery patients. The authors describe such a program operating in Halifax, Nova Scotia, designed to link volunteers who have successfully recovered from open-heart surgery with those individuals about to undergo similar surgery. Comparisons are also made with parallel support programs in Canada and the United States. Thus far, only crude measurements of the effectiveness of this particular social-support intervention are available. The dyadic social-support that volunteers offer cardiac surgery patients seems to be effective as evidenced by the information discussed in this paper.

Chronic illness and compliance.

For a person with a chronic illness, life is altered in some way. Whether simple or complex, changes are nevertheless permanent. A patient with a chronic disease assesses recommended treatments on how well they can be integrated into his life. Evidence suggests that an individual's perception of his situation will determine whether or not he will comply with a medical regimen. Health professionals neglect the patient's point of view if they believe that patients regard the health professional as an absolute authority, thereby contributing to noncompliance. The contingency contract provides a model of patient-provider transaction, which requires input from both parties. The health professional can work with the person to make the medical regimen compatible with the individual's lifestyle.

Diurnal flying activity and nutrition ecology of hydrotaea armipes fall. (Diptera, Muscidae).

The activity of the fly Hydrotaea armipes Fall. alighting on the lachrymous eyes of calves was observed. The flies were active throughout the day at the temperature higher than 12 degrees C, their activity inside the stable being about directly proportional to their activity in the paddocks. The numbers of active females indoors reached 0.08-17.3% of the number of active females in the paddocks. The flight range of females from paddocks or buildings for the housing of calves was no more than 10-20 m. The authors presume that the alighting H. armipes females orientate themselves to a greater distance (more than 5 m) visually, while in the approaching phase of their flight chemotactic orientation predominates in them.

The role of Hydrotaea armipes Fall. (Diptera, Muscidae) in the transmission of infectious bovine keratoconjunctivitis.

The tests to isolate the IBK causative agent Moraxella bovis from the flies Hydrotaea armipes Fall., captured while feeding on tears in the eye region of infected calves, have failed. Many successful isolations of Branhamella catarrhalis from the digestive tract of the flies and the smears taken from the eyes of the infected calves indicate that this agent is acquired by the flies while sucking tears from the eyes of the sick animals. A similar transmission is presumed by the authors with Moraxella bovis. In experiment this bacterium survives on the body surface of Hydrotaea armipes for 14 hours, in the digestive tract for 15 hours and even longer.

Synanthropy and faunistics of some Phoridae (Diptera) from Cuba.

Material of 498 specimens of 23 species of Phoridae collected by a trapping method in Cuba in 1966 is quantitatively and qualitatively analysed. A review of faunistic data, chorology, seasonal incidence and food preference is given and possible importance of the main species, mostly of the genus Megaselia, as potential vectors and causative agents of myiasis, is discussed.

To the knowledge of fauna of synanthropic flies of the Nepal Himalya.

A material of flies collected in two localities (altitude of 3900 and 4500 m) in the Barun Khola Valley (East Nepal) was studied, representing the early spring aspect of the species composition of flies. Of the total number of 2309 fly specimens 99.3% represented two species of the genus Paregle (P. aterrima, P. sp.); both are autochthonous high altitude hemisynanthrophic forms. The remainining 0.7% represent 9 species, most of which are more or less eurytopic species of palearctic or holoarctic distribution (Calliphora vicina, C. vomitoria, Meoneura flavifacies, Scatophaga stercoraria, Hydrotea hirticeps, Orthellia caesarian, Paregle danieli, Anthomyiidae g. sp. 1, g. sp. 2).

Synanthropy of Anthomyiidae, Muscidae and Calliphoridae (Diptera) in Cuba.

The material of 22302 flies of Anthomyiidae, Muscidae and Calliphoridae collected by trap-method in Cuba 1966 was qualitatively and quantitatively analysed. Relative density, seasonal incidence and food preference were ascertained in 20 species. In potential vectors of human diseases the ecological characters and classification of synanthropy are given.
