Spirituality of Thai Buddhists with chronic cardiovascular disease

Background. Advances in medical technology contribute to the survival rate of a growing number of persons with chronic illnesses. Individuals with chronic cardiovascular disease (chronic CVD) are among other chronically ill persons who add to the need for healthcare services. They need to cope and live with the chronic conditions and find a new balance to make sense of their lives. Thai Buddhists with chronic CVD may use their religious resources to cope with their illnesses because religious beliefs are reflected in patterns of living. The aims of the study were to: (a) explore how Thai Buddhists with chronic CVD construct the spiritual aspects of the illness experience, (b) explore how Thai Buddhists with chronic CVD may use their spiritual/religious resources as a means of coping with the illness, and (c) explore the impacts of spiritual/religious beliefs and/or practices on the daily lives of Thai Buddhists with chronic CVD. ^ Methods. Ethnography was employed and data were collected from December 1, 2007 to May 31, 2008 using in-depth interviews with 20 participants. Field notes were also recorded. ^ Findings. Three categories emerged from the study data: set of spiritual and biomedical beliefs and practices, integrated meanings, and positive consequences of the integration of spiritual and biomedical beliefs and practices. ^ Conclusions. The findings of the study suggest the importance of understanding and integrating spiritual needs into care of patients with chronic CVD. The findings revealed that the participants constructed ideas of their illness and meanings for living and coping with the illness, and integrated spiritual and biomedical beliefs and practices, resulting in positive outcomes. Further research could test interventions which facilitate such coping; for example, using reflective thinking and group support. Other studies might explore how age affects Buddhist views of the illness. ^

Proteomic identification of in vivo substrates for matrix metalloproteinases 2 and 9 reveals a mechanism for resolution of inflammation.

Clearance of allergic inflammatory cells from the lung through matrix metalloproteinases (MMPs) is necessary to prevent lethal asphyxiation, but mechanistic insight into this essential homeostatic process is lacking. In this study, we have used a proteomics approach to determine how MMPs promote egression of lung inflammatory cells through the airway. MMP2- and MMP9-dependent cleavage of individual Th2 chemokines modulated their chemotactic activity; however, the net effect of complementing bronchoalveolar lavage fluid of allergen-challenged MMP2(-/-)/MMP9(-/-) mice with active MMP2 and MMP9 was to markedly enhance its overall chemotactic activity. In the bronchoalveolar fluid of MMP2(-/-)/MMP9(-/-) allergic mice, we identified several chemotactic molecules that possessed putative MMP2 and MMP9 cleavage sites and were present as higher molecular mass species. In vitro cleavage assays and mass spectroscopy confirmed that three of the identified proteins, Ym1, S100A8, and S100A9, were substrates of MMP2, MMP9, or both. Function-blocking Abs to S100 proteins significantly altered allergic inflammatory cell migration into the alveolar space. Thus, an important effect of MMPs is to differentially modify chemotactic bioactivity through proteolytic processing of proteins present in the airway. These findings provide a molecular mechanism to explain the enhanced clearance of lung inflammatory cells through the airway and reveal a novel approach to target new therapies for asthma.
