Tiotropium is a long-acting inhaled anticholinergic agent that is widely used in the treatment of chronic obstructive pulmonary disease (COPD). It was initially launched as the tiotropium HandiHaler formulation, but this was followed by a newer version based on a potentially more efficient drug delivery device, known as Respimat. This Respimat formulation is available worldwide but has not yet succeeded in gaining regulatory approval in the USA. In the past few years, the adverse effects profile of tiotropium has come under close scrutiny owing to concerns about the possibility of urinary and cardiovascular adverse effects. These concerns appeared to have been alleviated following the publication of data from the Understanding Potential Long-Term Impacts on Function with Tiotropium (UPLIFT) trial, which was a large trial of 4 years’ duration. This trial did not show any excess myocardial infarction, renal or urinary adverse events with tiotropium compared with placebo. However, the risk of urinary retention has been in the spotlight again following publication of two observational studies reporting a significantly increased risk of urinary retention in men recently started on inhaled anticholinergics, especially when prostatic hyperplasia coexists. More recently, a meta-analysis of mortality data for the tiotropium Respimat formulation raised the possibility of an increased risk of death, including death from cardiovascular causes. It is unclear if the more efficient drug delivery offered by the Respimat device is hitting a different part of the dose-toxicity curve. In the absence of any evidence of superior clinical efficacy with tiotropium Respimat compared with tiotropium HandiHaler, some experts have argued that there is no compelling reason to choose the Respimat formulation given the new uncertainties about its safety profile.

Introduction: PAD was asymptomatic in a large proportion of COPD patients and was associated with more severe lung disease than in COPD subjects without PAD. Materials and Methods: This was a Cross-sectional study conducted at Department of Physiology, Santosh Medical College diagnosed with COPD using Spirometry was recruited for the study with a Sample size of 130 patients. Results: The characteristics of the population for follow-up (n=130) are presented in table 1. The mean Mean±SD was 51.73±6.1 years. The prevalence of never smokers was 21.5%, former smokers were 51.5% and current smokers were 26.9%. In total, 41 out of 130 individuals (31.5%) had PAD based on an ABI of less than 0.6. A statistically significant association was found between COPD and newly diagnosed PAD during follow-up. The association between COPD and incident PAD was stronger (adjusted OR 1.91, 95% CI 1.14–3.21). Stratified analysis by smoking status revealed that the overall association between COPD and newly developed PAD was driven by the ever smoker group. Conclusion: Subjects with COPD have a higher risk of developing PAD. People with both COPD and PAD have a substantially increased risk of death. Consequently, early detection of PAD and preventive actions in people with COPD should receive more attention in clinical respiratory care. Keywords: Peripheral Arterial Disease, Chronic Obstructive Pulmonary Disease, Ankle-brachial index.

This study tests our hypothesis that patients with chronic obstructive pulmonary disease (COPD) have an increased risk of traumatic brain injury (TBI).In this nationwide retrospective cohort study, we used a subset of Taiwan’s National Health Insurance Research Database, involving 1 million randomly selected beneficiaries. Patients with newly diagnosed COPD between 2000 and 2008 were identified. They were subgrouped as ‘COPDAE+’ (if they had severe acute exacerbation of COPD during the follow-ups) or ‘COPDAE−’ (if they had no acute exacerbation), and were frequency matched with randomly selected subjects without COPD (the ‘non-COPD’ group). Baseline differences were balanced by the inverse probability of treatment weighting based on the propensity score. For each patient, the risk of TBI during the subsequent 5 years was determined. The competing risk of death was controlled.We identified 3734 patients in ‘COPDAE+’, and frequency matched them with 11,202 patients in ‘COPDAE−’ and 11,202 subjects in ‘non-COPD’. Compared with those in ‘non-COPD’, patients in ‘COPDAE+’ and ‘COPDAE−’ had an increased risk of TBI: the adjusted HR for ‘COPDAE+’ was 1.50, 95% CI 1.31 to 1.73, and that for ‘COPDAE−’ was 1.21, 95% CI 1.09 to 1.34. The highest risk was observed in the ‘COPDAE+’ group that aged <65 (the adjusted HR was 1.92; 95% CI 1.39 to 2.64).COPD has been linked to complications beyond the respiratory system. In this study we showed that COPD is associated with an increased risk of TBI.

Abstract Background Previous studies have shown increased mortality in venous thromboembolism (VTE) patients with chronic obstructive pulmonary disease (COPD), but it is unknown to what extent the association is influenced by the severity of COPD and physical inactivity. Objectives This article investigates whether COPD, and stages of COPD, influenced the risk of mortality after a first episode of VTE when physical inactivity was taken into account. Methods Patients with a first lifetime VTE (n = 256) were recruited among individuals who participated and performed spirometry in the fifth (2001–2002) and sixth (2007–2008) surveys of the Tromsø Study (n = 9577). All-cause mortality was registered up to December 31, 2015. Results There were 123 deaths during a median of 2.9 years of follow-up. The overall mortality rate was 11.9 (95% confidence interval [CI] 10.0–14.2) per 100 person-years. The risk of death was twofold higher in COPD patients compared with those with normal airflow (hazard ratio [HR] 2.00, 95% CI 1.30–3.08) after multivariable adjustment. The risk of death increased with the severity of COPD. VTE patients with COPD stage III/IV had a fivefold increased risk of death (HR 5.20, 95% CI 2.65–10.2) compared with those without COPD, and 50% of these patients died within 3.5 months after the incident VTE event. Adjustment for physical inactivity had minor effect on the risk estimates. Conclusion VTE patients with COPD had increased risk of death, particularly patients with severe COPD. The detrimental effect of COPD on mortality in VTE patients was apparently explained by factors other than physical inactivity among patients with COPD.

Abstract Objective Chronic obstructive pulmonary disease (COPD) is a complicated multi-factor, multi-gene disease. Here, we aimed to assess the association of genetic polymorphisms in LINC01414/ LINC00824 and interactions with COPD susceptibility. Methods Three single nucleotide polymorphisms (SNPs) in LINC01414/LINC00824 was genotyped by Agena MassARRAY platform among 315 COPD patients and 314 controls. Logistic analysis adjusted by age and gender were applied to estimate the genetic contribution of selected SNPs to COPD susceptibility. Results LINC01414 rs699467 (OR = 0.73, 95% CI 0.56–0.94, p = 0.015) and LINC00824 rs7815944 (OR = 0.56, 95% CI 0.31–0.99, p = 0.046) might be protective factors for COPD occurrence, while LINC01414 rs298207 (OR = 2.88, 95% CI 1.31–6.31, p = 0.008) risk-allele was related to the increased risk of COPD in the whole population. Rs7815944 was associated with the reduced risk of COPD in the subjects aged > 70 years (OR = 0.29, p = 0.005). Rs6994670 (OR = 0.57, p = 0.007) contribute to a reduced COPD risk, while rs298207 (OR = 7.94, p = 0.009) was related to a higher susceptibility to COPD at age ≤ 70 years. Rs298207 (OR = 2.54, p = 0.043) and rs7815944 (OR = 0.43, p = 0.028) variants was associated COPD risk among males. Rs7815944 (OR = 0.16, p = 0.031) was related to the reduced susceptibility of COPD in former smokers. Moreover, the association between rs298207 genotype and COPD patients with dyspnea was found (OR = 0.50, p = 0.016), and rs7815944 was related to COPD patients with wheezing (OR = 0.22, p = 0.008). Conclusion Our finding provided further insights into LINC01414/LINC00824 polymorphisms at risk of COPD occurrence and accumulated evidence for the genetic susceptibility of COPD.

Abstract Background Available data on influenza burden across Southeast Asia are largely limited to pediatric populations, with inconsistent findings. Methods We conducted a multicenter, hospital-based active surveillance study of adults in Malaysia with community-acquired pneumonia (CAP), acute exacerbation of chronic obstructive pulmonary disease (AECOPD) and acute exacerbation of asthma (AEBA), who had influenza-like illness ≤10 days before hospitalization. We estimated the rate of laboratory-confirmed influenza and associated complications over 13 months (July 2018–August 2019) and described the distribution of causative influenza strains. We evaluated predictors of laboratory-confirmed influenza and severe clinical outcomes using multivariate analysis. Results Of 1106 included patients, 114 (10.3%) were influenza-positive; most were influenza A (85.1%), with A/H1N1pdm09 being the predominant circulating strain during the study following a shift from A/H3N2 from January–February 2019 onwards. In multivariate analyses, an absence of comorbidities (none versus any comorbidity [OR (95%CI), 0.565 (0.329–0.970)], p = 0.038) and of dyspnea (0.544 (0.341–0.868)], p = 0.011) were associated with increased risk of influenza positivity. Overall, 184/1106 (16.6%) patients were admitted to intensive care or high-dependency units (ICU/HDU) (13.2% were influenza positive) and 26/1106 (2.4%) died (2.6% were influenza positive). Males were more likely to have a severe outcome (ICU/HDU admission or death). Conclusions Influenza was a significant contributor to hospitalizations associated with CAP, AECOPD and AEBA. However, it was not associated with ICU/HDU admission in this population. Study registration, NMRR ID: NMRR-17-889-35,174.

Abstract There is an increased risk for burn injuries associated with home oxygen therapy of patients with chronic obstructive pulmonary disease since 10 to 50 % of these patients continue to smoke. Enzymatic eschar removal of facial burns is gaining popularity but intubation of this specific patient group often leads to prolonged weaning and can require tracheostomy. This study dealt with the question if enzymatic debridement in these patients can also be performed in analgosedation. A selective review of the literature regarding burn trauma associated with home oxygen use in patients with COPD was performed, as well as a retrospective analysis of all patients with burn injuries associated with home oxygen use and chronic obstructive pulmonary disease that were admitted to the study clinic. In the literature 1746 patients with burns associated with home oxygen use are described, but none of them received enzymatic debridement. In this study seventeen patients were included. All three patients in this study with facial full-thickness burn injuries received enzymatic debridement. The mortality rate in this cohort was 17.6 % (3/17). Up to date, there is limited experience performing regional anesthesia debridement in patients with COPD. This is the first manuscript describing the use of enzymatic debridement in patients with COPD and home oxygen therapy. We could confirm other studies that intubation of these patients leads to prolonged ventilation hours and increases the probability for poor prognosis. Therefore, we described the treatment of enzymatic debridement in analgosedation without intubation.

Malnutrition is one of the most important factors that lead to lower quality of life in patients suffering from chronic obstructive pulmonary disease (COPD). There are several methods for assessing malnutrition including anthropometric indexes. The aim of this study was to determine the association of anthropometric indexes with disease severity in male patients with COPD in Qazvin, Iran. This cross-sectional study was conducted on 72 male patients with COPD in Qazvin, Iran, from May to December 2014. Spirometry was performed for all participants. Disease severity was determined using the Global Initiative for Chronic Obstructive Lung Disease (GOLD) guideline. Body mass index (BMI), mid-arm muscle circumference (MAMC), and triceps skinfold thickness (TSF) were measured. MAMC and TSF were categorized into three subgroups as <25th P, between 25th P and 75th P, and >75th P (Where P is the abbreviation for percentile.). Data were analyzed using ANOVA and logistic regression analysis. Mean age was 60.23 ± 11.39 years. Mean BMI was 23.23 ± 4.42 Kg/m2, mean MAMC was 28.34 ± 3.72 cm2, and mean TSF was 10.15 ± 6.03 mm. Mean BMI and MAMC in the GOLD stage IV were significantly lower than other stages. Of 72, 18.1% were underweight while 6.9% were obese. The GOLD stage IV was associated with 16 times increased risk of underweight and nine times increased risk of MAMC < 25th P. Disease severity was associated with BMI and MAMC as indexes of malnutrition in patients with COPD in the present study. The GOLD stage IV was associated with increased risk of underweight and low MAMC.
