BackgroundNintedanib slows disease progression in patients with Idiopathic Pulmonary Fibrosis (IPF) by reducing decline in Forced Vital Capacity (FVC). The effects of nintedanib on abnormalities on high-resolution computed tomography scans have not been previously studied.ObjectiveWe conducted a Phase IIIb trial to assess the effects of nintedanib on changes in Quantitative Lung Fibrosis (QLF) score and other measures of disease progression in patients with IPF.Methods113 patients were randomized 1:1 to receive nintedanib 150 mg bid or placebo double-blind for ≥6 months, followed by open-label nintedanib. The primary endpoint was the relative change from baseline in QLF score (%) at month 6. Analyses were descriptive and exploratory.ResultsAdjusted mean relative changes from baseline in QLF score at month 6 were 11.4% in the nintedanib group (n=42) and 14.6% in the placebo group (n=45) (difference 3.2% [95% CI: -9.2, 15.6]). Adjusted mean absolute changes from baseline in QLF score at month 6 were 0.98% and 1.33% in these groups, respectively (difference 0.35% [95% CI: -1.27, 1.96]). Adjusted mean absolute changes from baseline in FVC at month 6 were -14.2 mL and -83.2 mL in the nintedanib (n=54) and placebo (n=54) groups, respectively (difference 69.0 mL [95% CI: -8.7, 146.8]).ConclusionExploratory data suggest that in patients with IPF, 6 months' treatment with nintedanib was associated with a numerically smaller degree of fibrotic change in the lungs and reduced FVC decline versus placebo. These data support previous findings that nintedanib slows the progression of IPF.

Background: Diseases affecting the cardiovascular system are the most common cause of death worldwide. In addition to classical risk factors of atherosclerosis, long-term exposure to particulate matter with particles of size up to 10 µm (PM10) in the atmosphere has become an increasing focus of scientific attention in recent decades. This study analyses the associations of residential-associated air pollutants exposure with all-cause mortality and cardiovascular morbidity of older patients in a primary care setting. Methods: The "German Epidemiological Trial on Ankle Brachial Index" (getABI) is a prospective cohort study that started in 2001 and included 6,880 primary care patients with a follow-up of 7 years. The PM10 and nitrogen dioxide (NO2) concentrations in the atmosphere are interpolated values from the study "Mapping of background air pollution at a fine spatial scale across the European Union". The primary outcome in this analysis is death of any cause, a secondary outcome is onset of PAD. Cox proportional hazards regression was used in a two-step modelling, the first step with basic adjustment only for age, sex, and one or more air pollutants, the second with additional risk factors. Results: A total of 6,819 getABI patients were included in this analysis. 1,243 of them died during the study period. The hazard ratio (HR) (1.218, 95%-confidence-interval (CI) 0.949–1.562) for the risk of death from any cause was elevated by 22% per 10 µg/m3 increase of PM10 in the fully adjusted model, although not statistically significant. Increased PM10 exposure in combination with the presence of PAD had a significantly increased risk (HR = 1.560, 95%-CI: 1.059-2.298) for this endpoint in the basic adjustment, but not in the fully adjusted model. 736 patients developed peripheral artery disease (PAD) during the course of the study. There was no association of air pollutants and the onset of PAD. Conclusions: Our analysis renders some hints for the impact of air pollutants (PM10, NO2, and proximity to major road) on mortality. Interaction of PAD with PM10 was found. There was no association of air pollutants and the onset of PAD. Trial registration: German Clinical Trials Register: DRKS00029733 (19/09/2022).

Abstract Background Exercise programmes can be administered successfully as therapeutic agents to patients with a number of chronic diseases and help to improve physical functioning in older adults. Usually, such programmes target either healthy and mobile community-dwelling seniors or elderly individuals living in nursing institutions or special residences. Chronically ill or mobility-restricted individuals, however, are difficult to reach when they live in their own homes. A pilot study has shown good feasibility of a home-based exercise programme that is delivered to this target group through cooperation between general practitioners and exercise therapists. A logical next step involves evaluation of the effects of the programme. Methods/design The study is designed as a randomised controlled trial. We plan to recruit 210 patients (≥ 70 years) in about 15 general practices. The experimental intervention (duration 12 weeks)-a multidimensional home-based exercise programme-is delivered to the participant by an exercise therapist in counselling sessions at the general practitioner's practice and on the telephone. It is based on methods and strategies for facilitating behaviour change according to the Health Action Process Approach (HAPA). The control intervention-baseline physical activities-differs from the experimental intervention with regard to content of the counselling sessions as well as to content and frequency of the promoted activities. Primary outcome is functional lower body strength measured by the "chair-rise" test. Secondary outcomes are: physical function (battery of motor tests), physical activity (step count), health-related quality of life (SF-8), fall-related self-efficacy (FES-I), and exercise self-efficacy (SSA-Scale). The hypothesis that there will be differences between the two groups (experimental/control) with respect to post-interventional chair-rise time will be tested using an ANCOVA with chair-rise time at baseline, treatment group, and study centre effects as explanatory variables. Analysis of the data will be undertaken using the principle of intention-to-treat. Trial registration Current Controlled Trials ISRCTN17727272.

Abstract Background A new vaccine against Rotavirus (RV) gastroenteritis was introduced in Germany in 2006. In 1997 the first RV vaccine was withdrawn due to an increased incidence in intussusception (IS). Thus, an accurate estimation of the incidence of IS is important for post-licensure surveillance. Methods IS-Data were obtained from the 'Erhebungseinheit für seltene pädiatrische Erkrankungen Deutschland' (ESPED, German surveillance unit for rare pediatric diseases) collaborations' central register where all cases of intussusception in Germany for the years 2006 and 2007 are collected (n = 1200). In order to obtain an unbiased estimate of the incidence, it is necessary to determine the population under risk out of which these cases originated, and the proportion of real cases not reported to the registry (underreporting). In order to assess underreporting, a random sample of 31 hospitals was re-assessed by an outside reviewer. The estimation of incidence was done using a single Maximum-Likelihood (ML) estimator based on data from both the registry and the sample. Results The uncorrected observed incidence was calculated to be 26.6/100,000 child-years for children below 1 year old, 23.8 for those below 2 years old, and 5.2 for those below 15 years old. The review revealed a mean reporting quota of about 41% and the ML approach yielded an incidence of 51.5/100,000 child-years (95%CI [41.7;61.1]) for children below 2 years of age. Conclusions While substantial under-reporting led to very conservative estimates of the IS incidence, the approach described here allows an accurate estimation of IS incidence including corresponding confidence bands. Therefore, ML estimation is a straightforward instrument to derive stable, unbiased estimates in epidemiological studies with incomplete data.

Objective: Clinical trials have shown that nintedanib 150 mg twice daily (bid) reduces disease progression in patients with idiopathic pulmonary fibrosis (IPF), with an adverse event profile that is manageable for most patients. Prior to the approval of nintedanib as a treatment for IPF in Brazil, an expanded access program (EAP) was initiated to provide early access to treatment and to evaluate the safety and tolerability of nintedanib in this patient population. Methods: Patients with a diagnosis of IPF within the previous five years, forced vital capacity (FVC) ≥ 50% predicted and diffusing capacity of the lungs for carbon monoxide (DLco) 30% to 79% predicted were eligible to participate in the EAP. Patients received nintedanib 150 mg bid open-label. Safety assessments included adverse events leading to permanent discontinuation of nintedanib and serious adverse events. Results: The EAP involved 57 patients at eight centers. Most patients were male (77.2%) and white (87.7%). At baseline, mean (SD) age was 70.7 (7.5) years and FVC w as 7 0.7 ( 12.5) % p redicted. M ean ( SD) e xposure t o n intedanib w as 1 4.4 ( 6.2) months; maximum exposure was 22.0 months. The most frequently reported adverse events considered by the investigator to be related to nintedanib treatment were diarrhea (45 patients, 78.9%) and nausea (25 patients, 43.9%). Adverse events led to permanent discontinuation of nintedanib in 16 patients (28.1%). Sixteen patients (28.1%) had a serious adverse event. Conclusion: In the Brazilian EAP, nintedanib had an acceptable safety and tolerability profile in patients with IPF, consistent with data from clinical trials. [ABSTRACT FROM AUTHOR]

We consider 2 problems of increasing importance in clinical dose finding studies. First, we assess the similarity of 2 non-linear regression models for 2 non-overlapping subgroups of patients over a restricted covariate space. To this end, we derive a confidence interval for the maximum difference between the 2 given models. If this confidence interval excludes the pre-specified equivalence margin, similarity of dose response can be claimed. Second, we address the problem of demonstrating the similarity of 2 target doses for 2 non-overlapping subgroups, using again an approach based on a confidence interval. We illustrate the proposed methods with a real case study and investigate their operating characteristics (coverage probabilities, Type I error rates, power) via simulation. [ABSTRACT FROM AUTHOR]

Background/objective: Low back pain affects many patients and has a high socioeconomic impact. Topical capsaicinoids have been used for decades to treat musculoskeletal pain. This study investigated the effects of the fixed dose combination (FDC) of nonivamide (a capsaicinoid) and nicoboxil (a nicotinic acid ester) cream in the treatment of acute nonspecific low back pain. Materials and methods: This phase III randomized, double-blind, placebo-controlled, multinational, multi-center trial investigated efficacy, safety, and tolerability of topical nicoboxil 1.08%/nonivamide 0.17% (Finalgon® cream) in treatment of acute nonspecific low back pain with the endpoints: pain intensity (PI) difference between pre-dose baseline and 8 hours after first application and the end of treatment, mobility score, and efficacy score. Results: Patients (n=138), 21-65 years of age, were treated for up to 4 days with FDC or placebo cream. Mean baseline PI was 6.8 on a 0-10 point numerical rating scale. After 8 hours, pain was more reduced with the FDC than with placebo (adjusted means: 2.824 vs. 0.975 points; p<0.0001). On the last treatment day, mean pain reduction by the FDC was stronger than with placebo (adjusted means: 5.132 vs. 2.174 points; p<0.0001). Mobility on Day 1 was in favor of the FDC when compared to placebo (odds ratio [95% confidence interval {CI}]: 7.200 [3.609, 14.363], p<0.0001). At the end of treatment, patients treated with the FDC rated efficacy significantly higher than placebo (odds ratio [95% CI]: 11.370 [5.342, 24.199], p<0.0001). Both treatments were tolerated well. No serious adverse events were reported. Conclusion: Nicoboxil/nonivamide cream is an effective and safe treatment for acute nonspecific low back pain, adding a promising treatment option.

Introduction: The safety, lung function efficacy, and symptomatic benefits of combined tiotropium and olodaterol in patients with COPD were established in the 1-year TONADO ® studies (NCT01431274; NCT01431287). As tiotropium is predominantly excreted by the kidneys, the long-term safety profile of tiotropium/olodaterol was investigated in patients with renal impairment in a prespecified safety analysis of the TONADO studies., Methods: These were 2 replicate, randomized, double-blind, parallel-group, 52-week Phase III studies that assessed tiotropium/olodaterol compared with tiotropium or olodaterol alone (all via Respimat ® ) in patients with moderate-to-very severe COPD. In this analysis, renal impairment was defined as mild (creatinine clearance [CLcr] 60-89 mL/min), moderate (CLcr 30-59 mL/min) or severe (CLcr 15-29 mL/min). Adverse events (AEs) were pooled from both studies., Results: Of 3,041 patients included in this analysis, 1,333 (43.8%) had mild, 404 (13.3%) had moderate, and 5 (0.2%) had severe renal impairment; these were distributed equally between treatment groups. Almost one-quarter of all treated patients (23.4%) had a history of cardiac disorder, 45.6% had hypertension, and 13.3% had glucose metabolism disorders, including diabetes. AEs with olodaterol, tiotropium, and tiotropium/olodaterol occurred in 75.1%, 70.8%, and 72.0% of patients with no renal impairment, 75.7%, 74.0%, and 73.3% with mild renal impairment, and 84.3%, 79.5%, and 79.7% with moderate renal impairment, respectively. There was no notable effect of renal impairment on the proportion of patients with an AE, and no differences were observed between tiotropium/olodaterol versus the monocomponents. There was no difference in the incidence of major adverse cardiac events, renal and urinary tract AEs, or potential anticholinergic effects with increasing severity of renal impairment., Conclusion: Over half the patients enrolled in the TONADO studies had renal impairment, and there was a high level of pre-existing cardiovascular comorbidity. The safety and tolerability of tiotropium/olodaterol is comparable to the monocomponents, irrespective of the level of renal impairment., Competing Interests: Disclosure RB reports personal fees from AstraZeneca, Boehringer Ingelheim, Chiesi, GlaxoSmithKline, Novartis, Roche, and Teva, as well as grants to Mainz University from Boehringer Ingelheim, GlaxoSmithKline, Novartis, and Roche, outside the submitted work.
