Objective To compare BODE index with GOLD staging for the severity evaluation in patients with chronic obstructive pulmonary disease ( COPD) . To investigate the relationship between BODE index and quality of life. Methods A total of 100 patients with stable COPD were enrolled. All participants were examined with lung function test and St George’s Respiratory Questionnaire ( SGRQ) for evaluation of quality of life. BODE index and it’s four components including body mass index( BMI) , airflow obstruction ( FEV1%pred) , dyspnea( MMRC) , and exercise capacity( 6MWD) were calculated. The participants were divided into four groups of severity using GOLD guidelines and BODE index quartiles. Results The associations between SGRQ total score and SGRQ subscales, and BODE index were significant( P lt;0. 01) .BODE index was a significant predictor of the quality of life, explaining 41. 3% of the total score of the SGRQ ( P lt;0. 01) . However, GOLD classification showed a correlation only with SGRQ activity score ( P lt;0. 05) but not with other SGRQ scores. There were significant differences in SGRQ total score and SGRQsubscales between different severity groups of BODE index( P lt;0. 01) . But there was no difference in SGRQ score between different severity groups of GOLD classification, except SGRQ activity score. Conclusion BODE scoring system is better correlated with the quality of life as assessed by the disease severity inpatients with COPD than the GOLD staging criteria.
Objective To investigate the effect of continuous positive airway pressure (CPAP) on sleep disorder and neuropsychological characteristics in patients with early Alzheimer’s disease (AD) combined with obstructive sleep apnea hypopnea syndrome (OSAHS). Methods A total of forty-two early AD patients with OSAHS were randomly divided into a CPAP combined treatment group (20 cases) and a simple medicine treatment group (22 cases). The changes of neurocognitive function were assessed by Montreal Cognitive Assessment (MoCA), Mini-mental State Examination (MMSE) and Hopkins Verbal Learning Test-revised (HVLT). Patient Health Questionnaire-9 (PHQ9) was used to evaluate the depression mood changes. The sleep characteristics and respiratory parameters were evaluated by polysomnography. The changes of the patients’ sleep status were assessed by Epworth Sleepiness Scale (ESS) and Pittsburgh Sleep Quality Index (PSQI). The changes of sleep status, cognitive function and mood in the CPAP combined treatment group were compared before and three months after CPAP treatment, and with the simple medicine treatment group. Results After three months of CPAP treatment, the ESS, PSQI and PHQ9 scores in the CPAP combined treatment group were significantly decreased compared with those before treatment, whereas MoCA, MMSE and HVLT (total scores and recall ) in the CPAP combined treatment group were increased compared with those before treatment (P<0.05). After CPAP treatment, the respiratory parameters apnea hypopnea index in the CPAP combined treatment group was significantly lower than that before treatment (P<0.05), and the minimum blood oxygen saturation was significantly higher than that before treatment (P<0.05). However, the sleep characteristics and parameters did not show statistically significant changes compared with those before treatment (P>0.05). The ESS, PSQI and PHQ9 scores were significantly reduced in the CPAP combined treatment group compared with the simple medicine treatment group (P<0.05), while there was no statistically significant changes of cognitive scores between the two groups (P>0.05). Conclusions The degree of low ventilation and hypoxia is alleviated, and the daytime sleepiness and depression is improved in early AD patients with OSAHS after three-month continuous CPAP treatment. Cognitive function is significantly improved, whereas there is no significant change in sleep structure disorder.
ObjectiveTo investigate the disease severity and comorbidities in outpatient with asthma from urban area in China.MethodsA face-to-face, questionnaire-based survey was carried out in outpatient department in 30 general hospitals from 30 provinces in China mainland except for Tibet during October 2015 to May 2016, and asthma patients who meet the including criteria were enrolled. Data of demographic characteristics, smoking status, disease severity, and comorbidities were collected.ResultsA total of 3 875 cases were included. According to GINA criteria, the proportion of diseases severity was as following: intermittent status 52.5% (2 033/3 875), mild persistent 24.5% (951/3 875), moderate persistent 16.9% (656/3 875), and severe persistent 6.1% (235/3 875). The overweight rate was 32.9% (1 274/3 875), the rate of obesity was 10.3% (401/3 875), and the smoking rate was 20.1% (777/3 875). Obesity and smoking were related to poor asthma control. 75.9% (2 941/3 875) of the patients had comorbidities: allergic rhinitis 43.4% (1682/3 875), hypertension 16.4% (634/3 875), nasosinusitis 8.7% (338/3 875), chronic obstructive pulmonary disease 7.3% (283/3 875), bronchiectasis 3.0% (118/3 875), and rhinopolypus 2.9% (114/3 875).ConclusionsThe majority of asthma patients from outpatient department are mild asthma patients. The proportion of allergic rhinitis and bronchiectasis in asthma patients is higher than mean level. Asthma patients with comorbidities of obesity and smoking is related to poor asthma control.
ObjectiveTo analyze the relationship between medication compliance of patients with uncontrolled asthma and lung function,airway inflammation level, asthma control level and quality of life so as to obtain important references for improving patient compliance and asthma control level in the future. MethodsQuestionnaires were performed in asthma patients who did not achieve asthma control and had poor compliance in 32 third-class hospitals in 28 provinces of China mainland. All patients were tested for lung function and airway inflammation levels. So the relevant data of asthma compliance was investigated and analyzed. ResultsA total of 923 patients were investigated and the questionnaire recovery rate was 100%. Two hundred and forty-three (26.33%) answered cognitive related questions about asthma completely correctly. Treatment compliance in asthma patients was positively correlated with lung function and significantly negatively correlated with exhaled nitric oxide. Better treatment compliance in asthma has higher level of asthma control and quality of life. Poor compliance in asthma patients will lead to decreased lung function and elevated levels of airway inflammation, resulting in decreased asthma control and quality of life. ConclusionAsthma treatment compliance is related to lung function, airway inflammation, asthma control level and quality of life.
