Airway clearance physiotherapy and health-related quality of life in cystic fibrosis.

Objective: Airway clearance physiotherapy is recommended in cystic fibrosis, but limited evidence exists to suggest how much treatment is enough. As a secondary analysis of a prior study investigating the safety, efficacy, and participants' perceptions of a novel airway clearance technique, specific cough technique (SCT) compared to forced expiration technique (FET), we aimed to evaluate whether the intervention was associated with changes in health-related quality of life (HRQoL).

Methods: We conducted randomised, controlled individual trials with six adults (N-of-1 RCTs).

Evaluation of a novel technique in airway clearance therapy - Specific Cough Technique (SCT) in cystic fibrosis: A pilot study of a series of N-of-1 randomised controlled trials.

Objectives: The aim of this pilot study was to evaluate the efficacy, safety and participants' perception of a novel technique in airway clearance therapy - specific cough technique in cystic fibrosis.

Methods: We conducted randomised controlled individual trials (N-of-1 randomised controlled trials) in six adults. Each trial included 8 weeks of treatment with two interventions each week, one with specific cough technique and one with forced expiration technique.

Pre-flight evaluation of adult patients with cystic fibrosis: a cross-sectional study.

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 (PaO), pulse oximetry (SpO) and cardiopulmonary exercise testing (CPET) at sea level (SL).

[Ulcerative colitis. Complications and sequelae in relation to the extent of the disease. A 10-year material].

Patients with ulcerative colitis in our catchment area were followed over a ten-years period with the focus on the relation between the extent of inflammation and complications. Total colitis was found in 180 out of 334 patients with known extension, while in 154 of the patients the inflammation was classified as left-sided colitis. The frequency of severe colitis, colectomy and cancer was more or less the same as stated in earlier reports.

All-trans retinoic acid directly inhibits granulocyte colony-stimulating factor-induced proliferation of CD34+ human hematopoietic progenitor cells.

In this study we examine the effects of retinoids on purified CD34+ human hematopoietic progenitor cells. All-trans retinoic acid inhibited granulocyte colony-stimulating factor (G-CSF)-induced proliferation of CD34+ cells in short-term liquid cultures in a dose-dependent fashion with maximal inhibition of 72% at a concentration of retinoic acid of 1 mumol/L. Although no significant effects were observed on granulocyte-macrophage CSF (GM-CSF)--interleukin-3--or stem cell factor (SCF)-induced proliferation, the combinations of G-CSF and each of these cytokines were all inhibited.
