  Background: Air travel may imply a health hazard for patients with cystic fibrosis (CF) due to hypobaric environment in the aircraft cabin. The objective was to identify pre-flight variables, which might predict severe hypoxaemia in adult CF patients during air travel. Methods: Thirty adult CF-patients underwent pre-flight evaluation with spirometry, arterial oxygen tension (PaO2), pulse oximetry (SpO2) and cardiopulmonary exercise testing (CPET) at sea level (SL). The results were related to the PaO2 obtained during a hypoxia-altitude simulation test (HAST) in which a cabin altitude of 2438 m (8000 ft) was simulated by breathing 15.1% oxygen. Results: Four patients fulfilled the criteria for supplemental oxygen during air travel (PaO2 HAST < 6.6 kPa). While walking slowly during HAST, another eleven patients dropped below PaO2 HAST 6.6 kPa. Variables obtained during CPET (PaO2 CPET, SpO2 CPET, minute ventilation/carbon dioxide output, maximal oxygen uptake) showed the strongest correlation to PaO2 HAST. Conclusions: Exercise testing might be of value for predicting in-flight hypoxaemia and thus the need for supplemental oxygen during air travel in CF patients.

  BackgroundAcute fire smoke inhalation injury involves inflammatory mediators whose roles are poorly understood. We carried out a prospective observational study of fire smoke victims to identify clinical and biochemical markers that may predict pulmonary dysfunction and investigated possible correlations between dysfunction and cytokines in bronchoalveolar lavage (BAL) fluid and blood. MethodsForty patients with respiratory and/or neurological symptoms following acute fire smoke inhalation had pulmonary function tests and blood gas analyses performed on admission, at discharge, and after 3 months. Cytokines were measured using BioPlex/XMap technology. ResultsOn admission, 30 (75%) patients had dyspnea. Patients presenting with bronchial wheezing (n = 14) had significantly lower PEF (201 l/min, 82-360) than non-wheezing patients (406 l/min, 100-683) (n = 16, P = 0.03). Bronchial wheezing predicted need for ICU treatment with OR = 93.3 at 95% CI (P < 0.001) and was associated with gas exchange impairment, with mean p(a)O(2)/FiO(2) ratio 34.4 (11.8-49.8) kPa on admission and 21.3 (8.3-44.5) kPa 48 h later. Blood HbCO also predicted ICU treatment, with OR = 1.58 at 95% CI (P < 0.001). Serum CRP, IL-6, IL-8, and MCP-1 were significantly higher in wheezing patients after 12-24 h compared with non-wheezing patients and study controls. Cytokine levels were still elevated after 3 months. BAL fluid had significantly higher levels of IL-8, MCP-1, IL-1, and G-CSF compared with healthy controls. ConclusionIn victims of fire smoke inhalation, pulmonary wheezing predicts inflammation, pulmonary dysfunction, respiratory failure, and need for intensive care.

  Background: Many patients with lung cancer are deconditioned with poor physical fitness. Lung resection reduces physical fitness further, impairing the patient's ability to function in daily life. Methods: We conducted a single-blind randomised controlled trial of high-intensity endurance and strength training (60 min, three times a week, 20 weeks), starting 5–7 weeks after surgery. The control group received standard postoperative care. The primary outcome was the change in peak oxygen uptake measured directly during walking until exhaustion. Other outcomes included changes in pulmonary function, muscular strength by one-repetition maximum (1RM), total muscle mass measured by dual energy X-ray absorptiometry, daily physical functioning and quality of life (QoL). Results: The intention-to-treat analysis of the 61 randomised patients showed that the exercise group had a greater increase in peak oxygen uptake (3.4 mL/kg/min between-group difference, p=0.002), carbon monoxide transfer factor (Tlco) (5.2% predicted, p=0.007), 1RM leg press (29.5 kg, p<0.001), chair stand (2.1 times p<0.001), stair run (4.3 steps, p=0.002) and total muscle mass (1.36 kg, p=0.012) compared with the controls. The mean±SD QoL (SF-36) physical component summary score was 51.8±5.5 and 43.3±11.3 (p=0.006), and the mental component summary score was 55.5±5.3 and 46.6±14.0 (p=0.015) in the exercise and control groups, respectively. Conclusions: In patients recently operated for lung cancer, high-intensity endurance and strength training was well tolerated and induced clinically significant improvements in peak oxygen uptake, Tlco, muscular strength, total muscle mass, functional fitness and QoL. This study may provide a basis for exercise therapy after lung cancer surgery.

  Fibrinogen in plasma includes three main fractions; high-molecular-weight (HMW)-fibrinogen, low-molecular-weight (LMW)-fibrinogen, and very-low-molecular-weight (LMW')-fibrinogen. During acute-phase conditions, plasma fibrinogen levels and the HMW-/LMW-fibrinogen ratio increase rapidly due to increased synthesis of HMW-fibrinogen. The consequences of elevated plasma fibrinogen levels and local deposition of fibrin in inflammatory tissues observed during acute-phase conditions are not clear. We wanted to investigate proinflammatory effects of fibrinogen and fibrin on peripheral blood mononuclear cells (PBMC) as reflected by altered mRNA expression and synthesis of the proinflammatory cytokines IL-6, TNF-alpha and IL-1beta, and to explore the significance of altered HMW-/LMW-fibrinogen ratio. PBMC were isolated from whole blood using Lymphoprep((R)). HMW-fibrinogen was separated from unfractioned fibrinogen by ammonium sulphate precipitation. Cells were incubated with unfractioned fibrinogen, HMW-fibrinogen or fibrin. Cytokine levels in cell lysates were determined using ELISA assays. Real-time PCR was used for mRNA quantification. We found that fibrinogen significantly increased mRNA levels, and induced synthesis of the proinflammatory cytokines IL-6 and TNF-alpha in PBMC in a dose dependent manner. Median (25, 75 percentile) IL-6 and TNF-alpha concentrations were 12 (5, 40) pg/ml and 16 (0,61) pg/ml, respectively. Median mRNA quantity was increased 12.3- (6.6, 48.6) and 1.7- (1.5, 6.5) fold for IL-6 and TNF-alpha compared to controls. The stimulatory effect of unfractioned fibrinogen was not significantly different from HMW-fibrinogen. Fibrinogen and fibrin were equally effective in promoting cytokine synthesis from PBMC. The results support that fibrin and fibrinogen may actively modulate the inflammatory process by inducing synthesis of proinflammatory cytokines from PBMC.

Blood Coagulation and Fibrinolysis.  ISSN 0957-5235.  17(6), s 471- 476 Show summary

  Moderate red wine consumption has been associated with decreased risk of coronary heart disease. Reduced plasma viscosity and fibrinogen levels have been launched as possible contributors to this risk reduction. The effect of moderate red wine consumption on plasma viscosity, however, has not been investigated in a prospective, randomized trial. We wanted to evaluate the effect of moderate red wine consumption on plasma viscosity, fibrinogen concentration and fibrinogen subfractions. Healthy, nonsmoking volunteers were assigned to consume one glass of red wine daily for 3 weeks in a prospective, randomized cross-over study. In the second 3-week period the volunteers abstained from alcohol use. The plasma viscosity, fibrinogen concentration and the distribution of the main fibrinogen subfractions were determined at inclusion, after wine drinking and after abstention. Plasma viscosity was reduced by 0.026 and 0.024 mPa.s in the two groups following wine intake (95% confidence interval, 0.009-0.043, P = 0.004; 95% confidence interval, 0.0083-0.039, P = 0.003). The decrease in plasma viscosity was maintained following 3 weeks of abstention. The fibrinogen concentration was reduced by 0.17 g/l following wine drinking in the group starting with abstention (95% confidence interval, 0.04-0.29, P = 0.01). The distribution of the fibrinogen subfractions remained unaltered. We conclude that a daily glass of red wine for 3 weeks significantly reduces plasma viscosity. Fibrinogen concentrations are also significantly reduced, when preceded by an abstention period. The decreased viscosity levels are maintained after 3 weeks of abstention, suggesting a sustained viscosity lowering effect of red wine.
