Acute respiratory distress syndrome: does histology matter?

Kao et al. have reported in Critical Care the histological findings of 101 patients with acute respiratory distress syndrome (ARDS) undergoing open lung biopsy. Diffuse alveolar damage (DAD), the histological hallmark of ARDS, was present in only 56.4 % of cases. The presence of DAD was associated with higher mortality. Evidence from this and other studies indicates that the clinical criteria for the diagnosis of ARDS identify DAD in only about half of the cases. On the contrary, there is evidence that the clinical course and outcome of ARDS differs in patients with DAD and in patients without DAD. The discovery of biomarkers for the physiological (increased alveolocapillary permeability) or histological (DAD) hallmarks of ARDS is thus of paramount importance. (Source: Critical Care)

Venous thromboembolism and lung cancer: a review

Abstract Venous thromboembolism (VTE) is a common complication of malignancies and epidemiological studies suggest that lung cancer belonged to the group of malignancies with the highest incidence rates of VTE. Risk factors for VTE in lung cancer patients are adenocarcinoma, NSCLC in comparison with SCLC, advanced disease, pneumonectomy, chemotherapy including antiangiogenic therapy. Other risk factors are pretreatment platelet counts and increased release of TF-positive microparticles. Elevated D-dimer levels do not necessarily indicate an increased risk of VTE but have been shown to be predictive for a worse clinical outcome in lung cancer patients. Mechanisms responsible for the increase in venous thrombosis in patients with lung cancer are not understood. Currently ...

The Tiotropium Safety and Performance in Respimat

Conclusions: The TIOSPIR® spirometry substudy showed that tiotropium Respimat® 5 μg was noninferior to tiotropium HandiHaler® 18 μg for trough FEV 1 , but Respimat® 2.5 μg was not. Tiotropium Respimat® 5 μg provides similar bronchodilator efficacy to tiotropium HandiHaler® 18 μg with comparable rates of FEV 1 decline. The rate of FEV 1 decline varied based on disease severity, with a steeper rate of decline observed in patients with moderate airway obstruction.Trial registrationNCT01126437.

High-Flow Nasal Cannula Therapy for Obstructive Sleep Apnea in Children

Conclusion:We present our successful experience of treating severe OSA with HFNC in the home setting. Further randomized controlled trials are needed to determine whether HFNC could be considered as an established alternative for CPAP in OSA in childrenCitation:Joseph L, Goldberg S, Shitrit M, Picard E. High-flow nasal cannula therapy for obstructive sleep apnea in children. J Clin Sleep Med 2015;11(9):1007–1010. (Source: Journal of Clinical Sleep Medicine : JCSM)

Efficacy of Bilevel-auto Treatment in Patients with Obstructive Sleep Apnea Not Responsive to or Intolerant of Continuous Positive Airway Pressure Ventilation

Conclusions:This study confirmed the role of Bilevel-auto as an effective therapeutic alternative to CPAP in patients intolerant of this latter mode of ventilation. Moreover, extending the use of Bilevel-auto to those OSA patients not responsive to CPAP, we showed a significantly better correction of nocturnal respiratory disturbances.Citation:Carlucci A, Ceriana P, Mancini M, Cirio S, Pierucci P, D'Artavilla Lupo N, Gadaleta F, Morrone E, Fanfulla F.
