Life after a cardiac event: women's experience in healing.

OBJECTIVE: To describe the experience of women's recovery after an acute cardiac event. DESIGN: Grounded theory provided the methodologic basis for qualitative data generation and analysis. SAMPLE: Thirteen women who had experienced an acute cardiac event. The participants' ages ranged from 42 to 78 with a mean age of 58 years. Four participants attended the group sessions after experiencing an acute myocardial infarction; five had undergone coronary artery bypass grafting; and two had undergone percutaneous transluminal coronary angioplasty. Two participants had undergone exercise testing that indicated myocardial ischemia. The time after the cardiac event ranged from 8 weeks to 3 years at the initiation of the study, with a mean time after the cardiac event of 8 months. RESULTS: Healing, the basic social process identified from the data, explained women's struggle through the uncertainty surrounding the cardiac event as a way of creating new and positive health patterns. The process of healing consisted of three stages: surviving, originating, and patterning balance. These stages of healing illustrated determinants of individual motivation that guided the initiation and maintenance of risk factor modification efforts in women after the cardiac event. CONCLUSIONS: Results of this study provide a basis for the development and evaluation of comprehensive rehabilitative interventions designed to enhance individual recovery after a cardiac event.

Wellness motivation theory: an exploration of theoretical relevance.

Data were collected from 14 older, rural African American men and women to explore how individual motivation affects the initiation and maintenance of health-related behavior. The research consisted of an inductive exploration designed to examine the validity and cultural relevance of an existing theoretical framework for wellness motivation in health behavior change. Through the technique of constant comparative analysis, the basic social process of empowering potential was substantiated as a process of individual growth and goal-directed behavior that facilitated the initiation and maintenance of positive health patterns. The process of empowering potential consisted of three stages: appraising readiness, changing, and integrating change. Two categories provided a cultural context for the process: health value orientation and network affiliation. The data validated and expanded a developing theoretical framework for wellness motivation in health behavior change.

Barriers to outpatient cardiac rehabilitation participation and adherence.

BACKGROUND: A significant proportion of eligible patients do not participate in outpatient cardiac rehabilitation. The purpose of this study was to identify barriers to participation and adherence to outpatient cardiac rehabilitation by querying program staff. METHODS: In January 1999, a survey was mailed to all North Carolina program directors of outpatient cardiac rehabilitation programs. The response rate was 85% (61/72). RESULTS: Across programs, the most common barrier to participation in outpatient cardiac rehabilitation was financial. Other barriers identified by program directors included lack of patient motivation, patient work or time conflicts, and lack of physician support or referral. When program directors were asked to cite reasons that referred patients provided for not participating in rehabilitation, the most common answer was financial or lack of motivation or commitment. The most common reason cited for dropping out of the rehabilitation program was work, followed by financial reasons and lack of motivation or commitment. CONCLUSIONS: The results of this statewide survey of program directors indicated a common set of barriers that many patients currently face to begin and continue participating in outpatient cardiac rehabilitation.

[Retinal detachment caused by giant tears: recent clinical results].

We perform surgery on ten eyes of ten patients of retinal Detachment with giant retinal tear. The surgical procedure induced lensectomy, vitrectomy, retinal incarceration, circumferential scleral buckling on 360 degrees, retinal tamponade with gaz (C3F8) and post-operative photocoagulation of the giant tear. Although most of cases was associated with massive proliferation vitreo-retinopathy, total retinal reattachment was achieved in five eyes.

Cell population obtained by bronchoalveolar lavage in Pneumocystis carinii pneumonitis.

In the course of bronchoalveolar lavages performed in 115 immunocompromised patients in order to investigate the occurrences of pneumonitis, Pneumocystis carinii pneumonia was diagnosed by demonstration of cysts in bronchoalveolar lavage specimens from 11 patients. The cellular phenomena associated with P. carinii infection at the level of the alveolar space were evaluated. Differential cell counts on bronchoalveolar lavage preparations stained by the May-Grünwald-Giemsa method were performed in immunocompromised patients and in ten nonimmunocompromised patients without any respiratory disease. A decrease in the alveolar macrophage count associated with an increase in the polymorphonuclear neutrophil count and the presence of plasma cells and/or immunoblasts was highly suggestive of P. carinii pneumonia. These cellular changes in bronchoalveolar lavage specimens are discussed in relation to the pathologic features usually described in P. carinii pneumonia.

[Pathology of perivascular spaces in the central nervous system].

The perivascular spaces of the central nervous system are involved in various pathological situations. The aim of this paper is to focus on the histopathological lesions of the perivascular spaces which commonly occur in the infectious (bacterial, viral, parasitic), tumoral (carcinoma, lymphoma, leukemia), demyelinating (multiple sclerosis, allergic encephalomyelitis) and vascular diseases of the brain. According to their apparent function in each of these situations an attempt was made to classify the main physiopathological processes involving the perivascular spaces into 3 distinct groups. The perivascular spaces may be considered as follows: (1) double way route between the parenchyma and the leptomeningeal space (extension to the brain of a meningeal pathological process, drainage of parenchymal wastes); (2) elective location of the inflammatory reaction partly as a result of the presence of connective tissue; (3) site of particular lesions such as dilatation, the pathogenesis of which remains unclear.

[Mechanical properties of the lung in paraquat-poisoned rats. Histopathologic correlates].

Paraquat intoxication in both the initial and late stages is responsible for a decrease in lung volumes and lung elasticity. In this study, we tried to separate these two stages with analysing the quasi-static pressure-volume curves (P-V) obtained both during inflation and deflation of the lungs. Three groups of rats were studied: group I: control (n = 9), group II: 11 animals studied 48 h after intraperitoneal injection of paraquat (24 mg X kg-1), group III: 6 animals studied 9 days after the administration of paraquat. Groups II and III, when compared to group I, were characterized by a significant decrease of 1) functional residual capacity (p less than 0.001), 2) the lung volume obtained for a 3 kPa distending pressure, and 3) the slope of the P-V curve during deflation (p less than 0.001). In group II, there was a clear increase in the hysteresis of the P-V loop due to an inflection of the inflation P-V limb. Such a shape is the only characteristic of the P-V curves which separates groups II and III. By contrast, the P-V curve during deflation, even when analysed with an exponential fitting, does not separate these two groups which were clearly different in their morphological aspect: alveolar edema (group II), interstitial pneumonitis (group III).

An exploration of the role of social networks in cardiovascular risk reduction.

OBJECTIVE: To identify and describe the role of social networks in influencing individual wellness motivation within the context of cardiac rehabilitation. DESIGN: A naturalistic design was used in the collection and analysis of inductively generated data. SAMPLE: Twenty-four individuals who were participating in an outpatient cardiac rehabilitation program. Of the 24 subjects sampled, 17 were men and seven were women. The respondents' ages ranged from 38 to 79 years, with a mean age of 58 years. At the time of the study, informants had been involved in cardiac rehabilitation for an average length of 10 weeks. RESULTS: Two primary categories were identified that describe informant perception of the role of social networks in motivating health behavior change: enabling and limiting. Subcategories identified were consistent with the general types of support described in social support literature (emotional, feedback, problem solving, instrumental), as well as behaviors found to diminish motivation in cardiovascular health behavior (value conflict, boundary maintenance). CONCLUSIONS: Findings from this study provide a better understanding of the role of social networks in motivating health behavior change within the contest of cardiac rehabilitation.
