Associations Between Religious/Spiritual Coping and Depression Among Adults with Cystic Fibrosis: A 12-Month Longitudinal Study.

Individuals with cystic fibrosis (CF) face a challenging disease, and depression is a significant concern. Many patients draw on religious/spiritual resources to assist them in managing the demands of chronic illness; however, these coping efforts rarely have been evaluated among adults with CF. This longitudinal study examined relationships between distinct types of positive and negative religious/spiritual coping at baseline (assessed with the RCOPE) and depression screening outcomes 12 month later (assessed with the Hospital Anxiety and Depression Scale). In logistic regression analyses controlling for disease severity (FEV1% predicted), lower likelihood of depression caseness at 12 months was predicted by higher general religiousness at baseline, greater use of benevolent religious reappraisal coping, greater use of spiritual connection coping, and lower spiritual discontent. Results suggest that distinct aspects religious/spiritual coping have differential associations with subsequent depression outcomes. Findings extend prior research to an important, understudied medical population, and address a clinically meaningful outcome.

Longitudinal associations between gratitude and depression 1 year later among adult cystic fibrosis patients.

Individuals with cystic fibrosis (CF) are confronted by a range of difficult physical and psychosocial sequelae. Gratitude has drawn growing attention as a psychosocial resource, but it has yet to be examined among adults with CF. The current investigation evaluated longitudinal associations between trait gratitude and subsequent outcomes from depression screening 12 months later, adjusting for disease severity (FEV1% predicted) and other significant clinical or demographic covariates. Participants were 69 adult CF patients recruited from a regional adult treatment center. They completed a validated measure of gratitude (Gratitude Questionnaire-6) at baseline and a screening measure of depression (Hospital Anxiety and Depression Scale) at 12-month follow-up. In a logistic regression analysis controlling for disease severity, higher levels of baseline gratitude were associated with reduced likelihood of depression caseness at 12 months (OR .83, 95% CI .73-.91, p = .001). Gratitude remained predictive after adjusting for other psychosocial resource variables (i.e., perceived social support and positive reframing coping). Findings offer an initial indication of the potential salutary role of dispositional gratitude in an understudied clinical population.

Persistent Adherence to Airway Clearance Therapy in Adults With Cystic Fibrosis.

BACKGROUND: Airway clearance therapy (ACT) is a core component of daily treatment for cystic fibrosis (CF). However, surprisingly little is known about sustained or persistent use of ACT over time among adults with CF. This longitudinal study examined persistent adherence to ACT over 12 months and its modifiable predictors, drawing on aspects of Social Cognitive Theory and the Theory of Planned Behavior. METHODS: Subjects were drawn from a regional CF center in the southern United States. Predictor variables evaluated at baseline included self-efficacy for ACT (ie, self-confidence in overcoming barriers), outcome expectations (ie, perceived necessity of ACT and concerns about its disruptive effects), and subjective norms (ie, perceptions of being influenced by others). The Cystic Fibrosis Treatment Questionnaire (CFTQ) was used to assess self-reported adherence to ACT at baseline, at 6 months, and at 12 months. RESULTS: The mean age of subjects was 27.2 ± 9.1 y, and mean FEV1% predicted was 65.5 ± 24.8. Forty-six percent of subjects reported persistent use of ACT (classified as adherent at all assessment periods). In bivariate analyses, all social cognitive predictor variables assessed at baseline were significantly related to persistent adherence (all P < .03), except subjective norms. In logistic regression analyses that modeled the effects of these predictors simultaneously while controlling for FEV1%, fewer baseline concerns about ACT (odds ratio = 0.82, 95% CI 0.69-0.99) and greater self-efficacy (odds ratio = 1.09, 95% CI 1.01-1.18) remained significant independent predictors. CONCLUSIONS: This longitudinal study addresses an important gap in the literature regarding adherence to ACT over time (12 mo) in a routine clinical setting. Persistent adherence was problematic. As anticipated, social cognitive variables (self-confidence and perceived concerns) predicted self-reported persistence, and these may represent practical targets for intervention.

Evaluation of obstructive lung disease with vibration response imaging.

As optimal treatment and prognosis differ between asthma and COPD, a new diagnostic approach to differentiating between the two disorders would be clinically desirable. We evaluated the utility of vibration response imaging in differentiating between asthma and COPD. Sixty-six subjects with asthma or COPD were recorded, before and after the administration of a short-acting bronchodilator, using a computerized lung sound analysis device. Gray-scale images of breath sound distribution in the lungs, quantitative data in breath sound graphs (timing, amplitude) and automatic crackle and wheeze detection programs were used to differentiate between asthma and COPD subjects. Imaging data were compared with the clinical diagnosis, made by the standard methods (medical history, physical examination, and spirometric indices). Blinded evaluation of images demonstrated a significantly higher rate of improvement in image dynamics, shape and overall improvement following bronchodilator in subjects with asthma compared with those with COPD. Quantitative data showed distinct patterns in timing and amplitude for these two pathologies. Combined analyses based on qualitative image evaluation and quantitative data demonstrated an overall 85% accuracy (84% for asthma, 86% for COPD) in differentiating between asthma and COPD. Combined qualitative and quantitative evaluations of lung sounds are quite sensitive in distinguishing between lung sound recordings of COPD and asthma individuals. Lung sound features of synchronization in timing and intensity provide objective data that may further differentiate these two airway disorders.

Gastric volvulus after ventricular assist device explantation and cardiac transplantation.

Diaphragmatic herniation has been recognized as a complication of unrepaired diaphragmatic defects after left ventricular assist device explantation and cardiac transplantation. We believe this to be the 1st report of diaphragmatic herniation that resulted in gastric volvulus in a cardiac transplant recipient. The presentation, diagnosis, and treatment of this potentially fatal condition are discussed herein. Nine months after removal of a Thoratec HeartMate II left ventricular assist device and orthotopic cardiac transplantation, the patient presented with intermittent upper abdominal and lower chest discomfort of 3 weeks' duration. Physical examination was notable for fullness in the upper abdomen. Plain radiographs and computed tomographic scans of the chest and abdomen without contrast were unexceptional. Two weeks later, the patient's pain began to worsen rapidly, and an upper gastrointestinal barium study revealed partial herniation of the stomach into the chest and omento-axial gastric volvulus without luminal obstruction. The patient underwent uncomplicated laparotomy for repair of the diaphragmatic defect and reduction of the herniated stomach. This case highlights the need for increased awareness of diaphragmatic herniation as a complication of unrepaired diaphragmatic defects so that diagnosis is not delayed, and underscores the importance of primary repair of all such defects to prevent future complications.

Review of ventilatory techniques to optimize mechanical ventilation in acute exacerbation of chronic obstructive pulmonary disease.

Chronic obstructive pulmonary disease (COPD) is a major global healthcare problem. Studies vary widely in the reported frequency of mechanical ventilation in acute exacerbations of COPD. Invasive intubation and mechanical ventilation may be associated with significant morbidity and mortality. A good understanding of the airway pathophysiology and lung mechanics in COPD is necessary to appropriately manage acute exacerbations and respiratory failure. The basic pathophysiology in COPD exacerbation is the critical expiratory airflow limitation with consequent dynamic hyperinflation. These changes lead to further derangement in ventilatory mechanics, muscle function and gas exchange which may result in respiratory failure. This review discusses the altered respiratory mechanics in COPD, ways to detect these changes in a ventilated patient and formulating ventilatory techniques to optimize management of respiratory failure due to exacerbation of COPD.
