Aim: To investigate gender-related information needs in patients with chronic obstructive pulmonary disease (COPD) using the Lung Information Needs Questionnaire (LINQ). Design: Cross-sectional, prospective cohort study. Methods: Patients with COPD receiving standardized self-management education including information regarding disease knowledge, medications, avoidance of exacerbation, smoking cessation, exercise, and nutrition were included. Gender differences were assessed by pulmonary function tests, 6-minute walking test, modified Medical Research Council dyspnea scale, Mini-Mental State Examination, St. George's Respiratory Questionnaire, and LINQ. Results: A total of 122 patients were enrolled. Females displayed significantly higher information needs for total LINQ score ( p < .001), avoidance of exacerbation ( p < .03), and nutrition ( p < .006). Significant correlations were seen between total LINQ score and gender ( p = .001), forced expiratory volume in 1 second, % predicted ( p = .003), and Mini-Mental State Examination ( p = .002) for male patients. In females, modified Medical Research Council dyspnea scale was correlated with the total LINQ score ( p = .04).

Abstract Background: Chronic obstructive pulmonary disease (COPD) is the most common chronic respiratory disease which is expected to become the third leading cause of death worldwide in 2030. Series of susceptibility genes and single nucleotide polymorphism (SNPs) play an important role in the occurrence and development of COPD.Methods: In our study, 98 COPD patients and 90 healthy volunteers were enrolled. The +869 SNP (SNP, Single Nucleotide Polymorphisms) of TGF-β1 was detected in 98 COPD patients and 90 healthy volunteers by PCR-DNA sequencing. The effects of different genotypes of +869 locus on the susceptibility of COPD, pulmonary function and airflow limitation of COPD patients were analyzed.Results: Allele C of +869 locus was associated with the susceptibility of COPD (OR:1.913, 95% CI: 1.251-2.926). The predicted value of FEV1% (FEV1, Forced Expiratory Volume in One Second) in patients with CC of +869 locus was significantly lower than that in patients with TT (P < 0.05). The genotype frequencies of CC, CT and TT were 6.5%, 58.7% and 34.8% in Mild-to-Moderate airflow restriction patients. In severe airflow restriction patients, the genotype frequencies were CC 23.1%, CT 57.7% and TT 19.2%. The distribution of CC genotype in severe airflow restriction COPD patients was significantly higher than that in Mild-to-Moderate airflow restriction COPD patients (P = 0.037). Moreover, the frequency of C allele was significantly higher in patients with severe airflow restriction than that patients with Mild-to-Moderate airflow restriction (P = 0.024).Conclusions: The SNP of +869 T/C in TGF-β1 is closely related to the susceptibility of COPD and the airflow restriction of COPD patients.

Adequate cognitive functioning in chronic obstructive pulmonary disease (COPD) patients is essential to understand the nature of the disease, adherence to treatment, and for leading a better quality of life. While cognitive impairment in severe forms of COPD have been well documented, identification of subclinical cognitive impairment in stable COPD patients remains crucial for planning prevention strategies. Hence the present study aimed to study and compare the cognitive function between the COPD patients, and normal individuals. The cognitive function was assessed in 42 stable COPD patients and 42 normal individuals with Mini Mental State Examination (MMSE), and auditory P300 event related potentials. Baseline characteristics and the cognitive parameters were compared between the COPD patients and the normal individuals; a p<0.05 was considered statistically significant. The latency of the P300 waves was significantly (p<0.05) prolonged (304.27±20.73 in COPD, 291.11± 24.53 in normal individuals), and the amplitude (4.36±1.56 in COPD, 5.46±3.12 in normal individuals) was significantly reduced in the COPD patients compared to the normal individuals. MMSE scores were also significantly (p<0.001) different between the COPD patients (26.97±0.89), and the normal individuals (27.80±0.83). Cognition may be affected even at the earlier stages of the disease among the COPD patients, as evident by changes in the P300 values. Auditory P300 event related potential may be used as an adjunct to the routine MMSE examination, as it serves as an effective tool in identifying the cognitive impairment in different stages of COPD. This may help the patients to adopt prevention strategies that help to avoid adverse effects on cognition in future.

The article summarizes the results of studies on the composition of microbial communities in stool samples of patients with chronic obstructive pulmonary disease (COPD) compared with healthy volunteers using genome-metagenomic sequencing. It is shown that the microbial community of the intestine in COPD patients is characterized as diverse taxonomic composition of metagenomes that the healthy volunteers microbiota. In this case, the normal composition of intestinal microbiota in patients with COPD is exposed to the qualitative and quantitative modifications. In contrast to healthy volunteers, the intestinal microbiota in patients with COPD is characterized by the presence of representatives of the Proteobacteria, as Citrobacter, Enterobacter, Eggerthella,Proteus, Salmonella, Anaerococcus, Clostridium difficile, Pseudomonas, as well as higher insemination fungus genusCandida (Candida dubliniensis and Candida albicans).

In a cross-sectional epidemiological study in Lieto, Finland, 61 men and 21 women with chronic obstructive pulmonary disease (COPD) were compared with age- and sex-matched controls from the same community to analyze the associations between COPD, cognitive performance, and occurrence of dementia. The cognitive assessment was based on the Mini-Mental State Examination (MMSE), previous clinical documents, and the assessment made by the research nurse after she had interviewed and tested each subject. These three measures revealed no differences between the COPD paients and the age-matched controls, and MMSE subtest scores did not differ significantly between the patients and controls. The findings suggest that the relative contribution of COPD to the occurrence of cognitive impairment and dementia in the elderly may be none or minimal at the community level.

Introduction The oral cavity and pharynx have a rich sensory system composed of specialized receptors. The integrity of oropharyngeal sensation is thought to be fundamental for safe and efficient swallowing. Chronic obstructive pulmonary disease (COPD) patients are at risk for oropharyngeal sensory impairment due to frequent use of inhaled medications and comorbidities including gastroesophageal reflux disease. Objective This study aimed to describe and compare oral and oropharyngeal sensory function measured using noninstrumental clinical methods in adults with COPD and healthy controls. Method Participants included 27 adults (18 men, nine women) with a diagnosis of COPD and a mean age of 66.56 years ( SD = 8.68). The control group comprised 11 healthy adults (five men, six women) with a mean age of 60.09 years ( SD = 11.57). Spirometry measures confirmed reduced functional expiratory volumes (% predicted) in the COPD patients compared to the control participants. All participants completed a case history interview and underwent clinical evaluation of oral and oropharyngeal sensation by a speech-language pathologist. The sensory evaluation explored the detection of tactile and temperature stimuli delivered by cotton swab to six locations in the oral cavity and two in the oropharynx as well as identification of the taste of stimuli administered in 5-ml boluses to the mouth. Analyses explored the frequencies of accurate responses regarding stimulus location, temperature and taste between groups, and between age groups (“≤ 65 years” and “> 65 years”) within the COPD cohort. Results We found significantly higher frequencies of reported use of inhaled medications ( p < .001) and xerostomia ( p = .003) in the COPD cohort. Oral cavity thermal sensation ( p = .009) was reduced in the COPD participants, and a significant age-related decline in gustatory sensation was found in the COPD group ( p = .018). Conclusion This study found that most of the measures of oral and oropharyngeal sensation remained intact in the COPD group. Oral thermal sensation was impaired in individuals with COPD, and reduced gustatory sensation was observed in the older COPD participants. Possible links between these results and the use of inhaled medication by individuals with COPD are discussed.

Background: A generic combination of fluticasone propionate and salmeterol xinafoate inhalation powder in a premetered, multidose, nonreusable inhaler was recently approved. Objective: To assess the performance of the generic device. Methods: Findings from three studies with regard to device usability, function, and robustness were reviewed. Results: In a study to assess device function in patients and healthy volunteers, the generic device was successfully used by patients with asthma and chronic obstructive pulmonary disease who were either dry powder inhaler users or dry powder inhaler‐naive, even though they were not trained beyond being provided the instructions for use. In a study to measure inhaled flow rates generated by patients and healthy volunteers, the generic device consistently simulated the delivery of a full dose of drug, even to patients with severe respiratory disease and reduced inspiratory flow rates. Although the generic device had a slightly higher airflow resistance, this study demonstrated that this difference did not result in any clinically meaningful differences in terms of drug delivery. Pressure drop, a key parameter that drives the fluidization and aerosolization of the powder dose, was found to be comparable between the devices. In an open-label study, the generic device met all U.S. Food and Drug Administration specifications for device robustness after 21.5 days of twice-daily dosing via oral inhalation among 111 participants with asthma or chronic obstructive pulmonary disease. All inhalers tested demonstrated conformity with a pharmacopeia with respect to key quality parameters (assay, delivered dose uniformity, aerodynamic size distribution). There was no evidence of chemical degradation of the active ingredients, nor of microbial or water ingress into the powder, as a result of inhaler use.
