Spiritual/religious coping and depressive symptoms in informal caregivers of hospitalized older adults

This aim of this study was assess whether positive and negative spiritual/religious coping (SRC) strategies are associated with depressive symptoms (DS) of informal caregiver (IC) of hospitalized older adults. A cross-sectional study was conducted among 98 IC of hospitalized older adults in the medical clinic of a Brazilian School Hospital. The functionality, Positive and Negative SRC strategies and DS were evaluated. The IC had high average use of SRC, with Positive SRC being more used than Negative SRC. In the unadjusted regression model, Positive and Negative SRC were associated with DS. However, when adjusted for confounding factors, only Negative SRC remained associated with DS. The IC had used their religious and spiritual beliefs as a way to cope with the stress that comes from caring for hospitalized older adults. Although the positive strategy use of these beliefs was more common, only the negative strategies were associated with a higher DS.     

A role for cysteinyl leukotrienes in airway remodeling in a mouse asthma model.

Airway inflammation and remodeling in chronic asthma are characterized by airway eosinophilia, hyperplasia of goblet cells and smooth muscle, and subepithelial fibrosis. We examined the role of leukotrienes in a mouse model of allergen-induced chronic lung inflammation and fibrosis. BALB/c mice, after intraperitoneal ovalbumin (OVA) sensitization on Days 0 and 14, received intranasal OVA periodically Days 14-75. The OVA-treated mice developed an extensive eosinophil and mononuclear cell inflammatory response, goblet cell hyperplasia, and mucus occlusion of the airways. A striking feature of this inflammatory response was the widespread deposition of collagen beneath the airway epithelial cell layer and also in the lung interstitium in the sites of leukocytic infiltration that was not observed in the saline-treated controls. The cysteinyl leukotriene(1) (CysLT(1)) receptor antagonist montelukast significantly reduced the airway eosinophil infiltration, mucus plugging, smooth muscle hyperplasia, and subepithelial fibrosis in the OVA-sensitized/challenged mice. The presence of Charcot-Leyden-like crystals in airway macrophages and the increased interleukin (IL)-4 and IL-13 mRNA expression in lung tissue and protein in BAL fluid seen in OVA-treated mice were also inhibited by CysLT(1) receptor blockade. These data suggest an important role for cysteinyl leukotrienes in the pathogenesis of chronic allergic airway inflammation with fibrosis.     

Management of hepatitis B in children

Children with hepatitis B infection require management by physicians knowledgeable about the natural history of this disorder and experienced in the treatment of children. Selection of appropriate pediatric patients for treatment will prevent some cases of advanced liver disease later in life. New treatments under development for adults may benefit children as well, once they have been rigorously investigated in the pediatric population. Prevention of new HBV infections is an important part of management in children, and working with public health campaigns will hopefully reduce both vertical and horizontal transmission.     

Does blood pressure differ between users and non-users of hormone replacement therapy? The Women's Health In the Lund Area (WHILA) Study

OBJECTIVE: To examine whether blood pressure over 24 h differed between postmenopausal women receiving and not receiving hormone replacement therapy. METHODS: One group of hormone replacement postmenopausal women (n = 32) and one group of non-hormone replacement (n = 32) postmenopausal women underwent non-invasive 24-h ambulatory blood pressure monitoring. They were randomly selected among the 2000 firstly screened women in an ongoing project in Lund, Sweden. The study was designed to detect a difference of 5 mmHg in diastolic blood pressure over 24 h with a power of 80% and 5% significance (two-tailed test). RESULTS: The hormone replacement women had a mean (SD) office blood pressure of 128/76 (12/8) mmHg and the non-hormone replacement 126/78 (16/8) mmHg. Mean ambulatory blood pressure over 24 h, day and night, in the hormone replacement group was 121/72 (11/7), 126/76 (12/8), 111/64 (11/7) mmHg. The corresponding values in the non-hormone replacement group were 118/72 (12/7), 124/77 (12/7), and 107/64 (13/7) (p > 0.40 for diastolic blood pressure and p > 0.20 for systolic blood pressure). Mean heart rate over 24 h was 71 (7) and 73 (8) beats/min in the hormone and non-hormone replacement groups, respectively. CONCLUSION: There was no difference in blood pressure or heart rate between the hormone replacement and non-hormone replacement postmenopausal women, either over 24 h or during the day or night. Hormone replacement in postmenopausal women seems not to have an influence on blood pressure, but of course we are aware that this is a cross-sectional study, which has its limitations.     

The role of fondaparinux as an adjunct to thrombolytic therapy in acute myocardial infarction: a subgroup analysis of the OASIS-6 trial.

AIMS: No antithrombotic therapy has been shown to reduce mortality when used with thrombolytics in acute myocardial infarction (AMI). In the OASIS-6 trial, fondaparinux significantly reduced mortality and reinfarction without increasing bleeding in 12 092 patients with acute ST elevation MI. METHODS AND RESULTS: We report the results of a subgroup analysis in the 5436 patients (45%) receiving thrombolytics. According to local practice, 4415 patients did not have an indication for unfractionated heparin (stratum 1) and 1021 did (stratum 2). Fondaparinux reduced the primary study outcome of death or MI at 30 days [Hazard ratio (HR) 0.79, 95% confidence interval (CI) 0.68-0.92] with consistent reductions in both mortality (HR and CI) and reinfarction (HR and CI). There was a non-significantly lower rate of stroke (HR 0.77, CI 0.48-1.25). The risk of severe bleeding was significantly reduced (HR 0.62, CI 0.40-0.94), and thus the balance of benefit and risk (death, MI and severe haemorrhage) was clearly reduced by fondaparinux (HR 0.77, 95% CI 0.67-0.90). Results were consistent in the two strata, by the different types of thrombolytics and across various time intervals from symptom onset to treatment. CONCLUSION: In STEMI patients treated with thrombolytic agents (predominantly streptokinase), fondaparinux significantly reduced the risk of death, re-MI and severe bleeds.     

Creation and maintenance of an adequate interatrial communication in left atrioventricular valve atresia or stenosis

Patients with left atrioventricular (AV) valve atresia or stenosis were studied retrospectively to determine the incidence of early and late failures of procedures to enlarge an interatrial communication. The 61 patients underwent 80 procedures: 5 balloon atrial septostomies, 12 blade atrial septostomies and 63 surgical septectomies. No balloon septostomy provided adequate long-term palliation. Of 12 blade septostomies, 4 resulted in gradients across the atrial septum of 5 to 8 mm Hg and 8 in gradients 3 mm Hg or less. Results from blade septostomy were unrelated to underlying diagnosis, age, gradient before the procedure, number of previous procedures, pulmonary blood flow or size of the postprocedure defect by balloon sizing, but were related to size of the postoperative defect estimated by echocardiography. Among 8 patients with gradients of 3 mm Hg or less after blade septostomy, 7 were followed 9 +/- 7 months and showed no evidence of restenosis. Of 63 surgical septectomies, 11 (17.5%) were inadequate, and in at least 7 cases the failure was due to restenosis of the defect as documented by serial catheterizations or echocardiograms. Outcome after surgical septectomy was unrelated to underlying diagnosis, age or number of previous procedures, but was related to size of the defect created. Our results reveal improved results in terms of residual gradient for blade septostomy compared with previous studies and the need to follow these patients carefully, even those undergoing surgical septectomy.
