2012
Objective To investigate the prevalence, determinants and spectrum of attention-deficit hyperactivity disorder (ADHD) medication and its associations with socioeconomic status (SES), health-related behaviour and living conditions. Design Observational cross-sectional study. Setting Germany. Participants Representative population-based sample of non-institutionalised youth aged between 0 and 17 years (n=17 450) and examined between 2003 and 2006. Main outcome measure Prevalence and spectrum of ADHD medication (Anatomical Therapeutic Chemical (ATC) code N04BA) measured by standardised computer-assisted personal interview (CAPI) on drug use. Results The overall prevalence of ADHD medication (s…
Sociodemographic factors associated with time to discharge for hospitalised patients with asthma and asthma exacerbation using the Ghana Health Servi…
2021
ObjectiveData on asthma hospitalisations are a useful source of patient morbidity information. In Ghana, the length of stay (LoS) and sociodemographic factors of patients hospitalised for asthma and its exacerbation are understudied. We aimed to investigate the time to discharge and assessed factors associated with length of hospital stays of asthmatics in Ghana.MethodsRetrospective analysis of hospitalised patient with asthma records between 2012 and 2017 from the nationwide Ghana Health Service District Health Information Management System 2 database. We calculated the cumulative incidence function for discharge stratified by age group and sex. Multivariable Cox regression was used to inv…
Coil embolisation for massive haemoptysis in cystic fibrosis.
2021
IntroductionMassive haemoptysis is a life-threatening event in advanced cystic fibrosis (CF) lung disease with bronchial artery embolisation (BAE) as standard of care treatment. The aim of our study was to scrutinise short-term and long-term outcomes of patients with CF and haemoptysis after BAE using coils.MethodsWe carried out a retrospective cohort study of 34 adult patients treated for massive haemoptysis with super selective bronchial artery coil embolisation (ssBACE) between January 2008 and February 2015. Embolisation protocol was restricted to the culprit vessel(s) and three lobes maximum. Demographic data, functional end-expiratory volume in 1 s in % predicted (FEV1% pred.) and bod…
Against all odds: anti-IgE for intrinsic asthma?
2013
For many years, pathogenetic concepts and the results of clinical trials supported the view that anti-IgE treatment is specifically effective in allergic asthma. However, there is now growing clinical and mechanistic evidence suggesting that treatment with the anti-IgE antibody omalizumab can be effective in patients with intrinsic asthma. Therefore, large and well-controlled clinical trials with anti-IgE are urgently warranted in patients with intrinsic asthma. In addition, there is a need to find new biomarkers which can identify patients with asthma who respond to anti-IgE treatment.
Authors' response to: epithelial mesenchymal transition (EMT) in small airways of COPD patient.
2013
We understand the reservations highlighted by Sohal and Walters in their letter in response to our recent work published.1 In their letter, Sohal and Walters argue that E-cadherin and ZO-1 are absent in our immunohistochemistry analysis of small bronchi of smokers and COPD patients, and that if disappeared completely epithelium would fall apart.1 In our study, we detected downregulation of E-cadherin and ZO-1 as well as a change of intercellular and apical distribution to diffuse cytoplasmic redistribution (figure 3B; in our work published in Thorax on 7 January 2013),2 but not …
Aclidinium inhibits human lung fibroblast to myofibroblast transition
2011
Background Fibroblast to myofibroblast transition is believed to contribute to airway remodelling in lung diseases such as asthma and chronic obstructive pulmonary disease. This study examines the role of aclidinium, a new long-acting muscarinic antagonist, on human fibroblast to myofibroblast transition. Methods Human bronchial fibroblasts were stimulated with carbachol (10 −8 to 10 −5 M) or transforming growth factor-β1 (TGF-β1; 2 ng/ml) in the presence or absence of aclidinium (10 −9 to 10 −7 M) or different drug modulators for 48 h. Characterisation of myofibroblasts was performed by analysis of collagen type I and α-smooth muscle actin (α-SMA) mRNA and protein expression as well as α…
The effect of tiotropium/olodaterol versus fluticasone propionate/salmeterol on left ventricular filling and lung hyperinflation in patients with COPD
2020
This exploratory, randomised, double-blind, double-dummy, multicentre, cross-over study explored the effect of 6 weeks of treatment with tiotropium/olodaterol (T/O) versus fluticasone propionate/salmeterol (F/S) on left ventricular filling in patients with chronic obstructive pulmonary disease with functional residual capacity (FRC) >120% predicted and postbronchodilator improvement of FRC ≥7.5%. Overall, 76 patients were randomised across nine sites. Treatment with T/O or F/S increased left ventricular end-diastolic volume index from baseline (adjusted mean change: T/O: 2.317 mL/m2, F/S: 2.855 mL/m2), with no statistically significant difference between treatments. However, T/O resulted…
Randomised comparison of zofenopril and ramipril plus acetylsalicylic acid in postmyocardial infarction patients with left ventricular systolic dysfu…
2015
Objective Conflicting evidence exists on the benefits of treating patients with coronary artery disease and preserved left ventricular ejection fraction (LVEF) with an ACE inhibitor. This retrospective analysis of the SMILE-4 Study sought to compare the efficacy of zofenopril 60 mg plus acetylsalicylic acid (ASA) versus ramipril 10 mg plus ASA 100 mg in patients with acute myocardial infarction (AMI) and heart failure, according to an impaired or preserved LVEF. Methods The primary study end point was 1-year combined occurrence of death or hospitalisation for cardiovascular causes. A preserved LVEF was defined by a baseline LVEF >40% and an impaired one by an LVEF ≤40%. Results 448 patients…
Rethinking the role of fat oxidation: substrate utilisation during high-intensity interval training in well-trained and recreationally trained runners
2015
Background Although carbohydrate is the predominant fuel source supporting high-intensity exercise workloads, the role of fat oxidation, and the degree to which it may be altered by training status, is less certain. Methods We compared substrate oxidation rates, using indirect calorimetry, during a high-intensity interval training (HIT) session in well-trained (WT) and recreationally trained (RT) runners. Following preliminary testing, 9 WT (VO2max 71±5 mL/min/kg) and 9 RT (VO2max 55±5 mL/min/kg) male runners performed a self-paced HIT sequence consisting of six, 4 min work bouts separated by 2 min recovery periods on a motorised treadmill set at a 5% gradient. Results WT and RT runners per…
