Background
Few studies are available regarding the annual decline of forced expiratory volume in 1 s (FEV1) in chronic obstructive pulmonary disease patients with mild airflow obstruction. This study sought to clarify to what extent cigarette-smoking individuals with mild airflow obstruction lose pulmonary function annually.Methods
From 2004 to 2006, pulmonary function tests were performed on people >40 years of age, during the annual health checkup held in Takahata, Yamagata, Japan (initial study population, n=3253). In 2011, pulmonary function tests were performed again on participants who agreed to undergo reexamination (follow-up study population, n=838).Results
Smokers have decreased pulmonary function in terms of percent forced vital capacity (FVC), %FEV1, and FEV1/FVC; the stages of airflow obstruction were also more severe in smokers than never-smokers. The annual decline in FEV1 was significantly greater in smokers than in never-smokers. The median annual decline in FEV1 was most significant in individuals with mild airflow obstruction. The annual decline in FEV1 was greater in smokers with mild airflow obstruction than in smokers with moderate airflow obstruction. In analyzing the decline in %FEV1, the annual change in smokers with mild airflow obstruction was greater than that in smokers with normal spirometric values.Conclusion
The annual decline in FEV1 was most significant in smokers with mild airflow obstruction in a Japanese general population. This highlights the importance of early detection of chronic obstructive pulmonary disease patients among the general population in order to prevent disease progression in undiagnosed patients. 相似文献2.

Background
Chronic obstructive pulmonary disease (COPD) patients experience multiple symptoms including dyspnea, anxiety, depression, and fatigue, which are highly correlated with each other. Together, those symptoms may contribute to impaired physical performance.Objectives
The purpose of this study was to examine interrelationships among dyspnea, anxiety, depressive symptoms, and fatigue as contributing factors to physical performance in COPD.Methods
This study used baseline data of 282 COPD patients from a longitudinal observational study to explore the relationship between depression, inflammation, and functional status. Data analyses included confirmatory factor analyses and structural equation modeling.Results
Dyspnea, anxiety and depression had direct effects on fatigue, and both dyspnea and anxiety had direct effects on physical performance. Higher levels of dyspnea were significantly associated with impaired physical performance whereas higher levels of anxiety were significantly associated with enhanced physical performance.Conclusion
Dyspnea was the strongest predictor of impaired physical performance in patients with COPD. 相似文献3.

Background
Cough and sputum production (symptoms of bronchitis) are common in chronic obstructive pulmonary disease (COPD). Extrapulmonary comorbidities, such as gastroesophageal reflux disease (GERD) and post-nasal drip, also cause bronchitis symptoms. The impact of extrapulmonary comorbidities on the severity of bronchitis symptoms in COPD is unknown. The aim of this study was to quantify bronchitis symptoms and assess the impact of GERD and nasal symptoms on the severity of bronchitis symptoms in COPD.Methods
In this cross-sectional study, stable COPD patients were recruited and completed the COPD assessment test (CAT) and Cough and Sputum Assessment Questionnaire (CASA-Q) to quantify bronchitis symptoms. To evaluate extrapulmonary comorbidities, the Frequency Scale for Symptoms of GERD (FSSG) questionnaire and nasal symptom questionnaire were completed. The impact of these comorbidities on the severity of bronchitis symptoms was analyzed.Results
Ninety-nine COPD patients were recruited. The presence of GERD symptoms (24.2% in the study population) was associated with more sputum symptoms. The presence of nasal discharge (43.4%) was associated with more cough and sputum symptoms, whereas post-nasal drip (13.1%) was associated with more sputum symptoms. On multivariate analyses, nasal discharge was associated with more cough symptoms. GERD and post-nasal drip were associated with more sputum symptoms.Conclusion
This study showed that the presence of GERD and/or nasal symptoms is associated with an increase in bronchitis symptoms. Careful assessment of extrapulmonary comorbidities is necessary in the evaluation of bronchitis symptoms in COPD patients. 相似文献4.

Background
Pulmonary function tests (PFTs) comprise the traditional method for detecting central airway obstruction (CAO) and evaluating therapeutic effects, but are effort-dependent. By contrast, the forced oscillation technique (FOT) is performed during tidal breathing in an effort-independent mode and is universally used to assess respiratory function in patients with chronic obstructive pulmonary disease (COPD) and asthma. We used the FOT to measure airway resistance and reactance in patients with CAO before and after interventional bronchoscopy and compared the results to data obtained using PFTs.Methods
Twelve patients with CAO were recruited from December 2013 to July 2016. The FOT, PFTs, chest computed tomography (CT), COPD Assessment Test (CAT), and the modified Medical Research Council (mMRC) dyspnea scale were employed before and after interventional bronchoscopy. The minimum airway cross-sectional area (MACSA) was calculated using a CT image calculator.Results
Of the 12 patients, 6 had tracheal obstruction and 6 had bronchial obstruction. All FOT measurements, except ΔX5, were significantly improved after interventional bronchoscopy in all cases. The significance of the improvement was greater with the FOT than PFTs. The MACSA, CAT, and mMRC dyspnea scale scores also significantly improved in all cases. Furthermore, only alteration of resistance at 20?Hz (R20) significantly correlated with the alteration of the MACSA after intervention. No significant correlations were found for PFTs.Conclusions
The FOT is suitable and convenient for assessing therapeutic results in patients with tracheobronchial CAO. The alteration of R20 is useful for estimating the airway dilation of CAO after interventional bronchoscopy. 相似文献5.

Background
The prevalence of chronic obstructive pulmonary disease (COPD) in smokers enrolled as “healthy” controls in studies is 10–50%. The COPD status of ideal smoker populations for lung cancer case-control studies should be checked via spirometry; however, this is often not feasible, because no medical indications exist for asymptomatic smokers to undergo spirometry prior to study enrollment. Therefore, there is an unmet need for robust, cost effective assays for identifying undiagnosed lung disease among asymptomatic smokers. Such assays would help excluding unhealthy smokers from lung cancer case-control studies.Methods
We used the cytokinesis-blocked micronucleus (CBMN) assay (a measure of genetic instability) to identify undiagnosed lung disease among asymptomatic smokers. We used a convenience population from an on-going lung cancer case-control study including smokers with lung cancer (n = 454), smoker controls (n = 797), and a self-reported COPD (n = 200) contingent within the smoker controls.Results
Significant differences for all CBMN endpoints were observed when comparing lung cancer to All controls (which included COPD) and Healthy controls (with no COPD). The risk ratio (RR) was increased in the COPD group vs. Healthy controls for nuclear buds (RR 1.28, 95% confidence interval 1.01–1.62), and marginally increased for micronuclei (RR 1.06, 0.98–1.89) and nucleoplasmic bridges (RR 1.07, 0.97–1.15).Conclusion
These findings highlight the importance of using truly healthy controls in studies geared toward assessment of lung cancer risk. Using genetic instability biomarkers would facilitate the identification of smokers susceptible to tobacco smoke carcinogens and therefore predisposed to either disease. 相似文献6.

Background
The designation of some cardiac-specific proteins as prognostic biomarkers in chronic obstructive pulmonary disease (COPD) exacerbations suggest that the process of exacerbation involves cardiomyocyte injury. Among these cardiac biomarkers, heart-type fatty acid binding protein (h-FABP) is considered a very sensitive diagnostic marker for cardiomyocyte injury and a prognostic marker in chronic heart failure. However, the prognostic usefulness of h-FABP in patients with COPD remains unclear.Methods
Sixty-six patients were enrolled in this study. Subjects who recovered from COPD exacerbation and were discharged without needing home oxygen therapy were defined as the improved group. Those who died of the COPD exacerbations, were discharged but needed home oxygen therapy, or were transferred to a rehabilitation hospital for respiratory failure and the remaining aftereffects of exacerbation were defined as the unimproved group.Results
The improved and unimproved groups included 54 and 12 subjects, respectively. Compared with the improved group, the unimproved group had significantly higher white blood cell counts and alanine aminotransferase, lactate dehydrogenase, blood urea nitrogen (BUN), uric acid, potassium, and h-FABP levels, and significantly lower total protein and total cholesterol levels and estimated glomerular filtration rates, either at admission or during the early morning within 24 h after admission. A multivariate analysis revealed that higher serum h-FABP and potassium levels were independently predictive of a poor prognosis following a COPD exacerbation, and a receiver operating characteristic curve analysis yielded a cutoff of 4.5 ng/ml for predicting lack of improvement.Conclusion
H-FABP may predict the outcomes of COPD exacerbation. 相似文献7.

Background
Field walk tests such as the incremental shuttle walk test (ISWT) are simple tests for assessing the degree of disability in individuals with chronic obstructive pulmonary disease (COPD). In the present study, the correlations between exercise performance in the ISWT, lung function, and health status were examined in patients with COPD of varying severities.Methods
A retrospective examination of 277 COPD patients was performed using the ISWT and lung function tests along with assessment of health status using St. George?s Respiratory Questionnaire (SGRQ). In addition, we assessed the correlations between the walking distance, lung function parameters, and SGRQ scores.Results
ISWT distances were poorly correlated with lung function parameters and SGRQ scores in mild COPD patients. In contrast, ISWT distances were significantly correlated with pulmonary function parameters, such as vital capacity (%predicted) and forced expiratory volume in one second, and SGRQ scores in moderate and severe COPD patients.Conclusions
The ISWT is more independent of health status and pulmonary function in patients with mild COPD compared to moderate or severe cases. Therefore, the exercise capacity of patients with mild COPD should be estimated by the ISWT. 相似文献8.

Background
Patients of diabetes mellitus experience psychological difficulties associated with their disease which remains unrecognized involving several states related to coping with diabetes. Diabetes distress is a distinct condition which is often mistaken for depression and is related to adverse disease outcomes.Aims and objective
To study the prevalence and predictors of diabetes distress in patients of Type 2 Diabetes mellitus (T2DM) in a tertiary care centre.Materials and methods
This cross-sectional study was conducted over a period of one year at Endocrine OPD of Pt. B.D. Sharma PGIMS, Rohtak, a tertiary care centre in northern India. 410 consecutive patients having T2DM attending the endocrine OPD were screened for psychiatric disorders and 189 diabetic patients with no underlying psychiatric disorders were included in the study. Their socio-demographic and relevant clinical variables were recorded. Diabetes Distress Scale (DDS) was used to measure distress due to the disease in these patients.Results
It was found that the prevalence of diabetes distress was 18.0%; among them 16.1% had emotion related distress, 5.6% regimen related distress, 1.5% interpersonal related distress and 1.2% physician related diabetes distress. The major predictors for high diabetes distress scores among diabetic cases were low education level, retinopathy, neuropathy and hypertension.Conclusion
The present study suggests that emotion related diabetes distress was more prevalent among diabetic patients. Lower education level and the presence of diabetic complications contribute as risk factors for high diabetes distress. 相似文献9.

Background
There is limited information about the respiratory function of ever-smokers without lung disorders. We sought to assess the effects of smoking habits on respiratory function in subjects without lung disorders.Methods
Subjects were recruited from among patients without any evidence of respiratory disorders who visited rural primary care clinics. Each participant was asked to answer a questionnaire that included questions smoking history. Their forced vital capacity (FVC) and forced expiratory volume in one second (FEV1) were measured.Results
We analyzed 802 subjects (364 men and 438 women). The means of the lambda-mu-sigma method derived z-score of FEV1 (zFEV1) both in current-smokers and ex-smokers were lower than that in never-smokers. The mean zFEV1 in the ever-smokers with more than 30 pack-years of smoking history were lower than that in the ever-smokers with less smoking history. Univariate analysis showed that there were significant negative correlations between pack-years and zFEV1 both in the ex-smokers and current-smokers. There was no significant correlation between the duration of smoking cessation and zFEV1 in the ex-smokers.Conclusions
Our data suggests that respiratory function in healthy ever-smokers is decreased based on smoking habits in a dose-dependent manner. Even after a long period of smoking cessation, the decreased respiratory function seems to be maintained in ex-smokers. 相似文献10.

Aims
This study aimed to characterize and estimate prevalence and frequency of mild to moderate hypoglycemia and potentially associated factors in a population of type 2 diabetes mellitus (T2DM) patients treated at ambulatory care level.Methods
HIPOS-PHARMA was a nationwide observational, cross-sectional, multicenter study conducted in community pharmacies, which surveyed T2DM patients treated for at least 3 months.Results
Overall, 233 pharmacies recruited 1890 patients (males: 50.6%) with mean 67.1 years. On average, participants reported having diabetes for 11.8 years. A total of 86.9% had at least one chronic illness or complication of diabetes, and 76.8% were usually followed in the primary care setting. Fifty eight percent were treated without a secretagogue or insulin. Overall prevalence of mild to moderate hypoglycemic episodes in the 3 months prior to recruitment was 17.8%. A 3.13% prevalence of severe hypoglycemia was observed in the last 12 months. Results suggested that men and patients on antihyperglycemic therapies excluding secretagogues or insulin were less likely to have mild to moderate hypoglycemic episodes.Conclusions
Mild to moderate hypoglycemic episodes were commonly reported, and factors like type of antihyperglycemic therapy, duration of disease and due complications may contribute. Almost half of episodes were not reported. Such factors should be considered in T2DM management. 相似文献11.

Aim
The burden of diabetes is very high in our country particularly in the urban metros. The present survey was planned to ascertain the current prevalence of diabetes and prediabetes in Delhi since the available prevalence estimates are over a decade old.Methods
The present study was conducted in urban area of east Delhi and followed a multistage random sampling design. The prevalence of known diabetes was ascertained based on self reporting and prevalence of newly detected diabetes and prediabetes was based on oral glucose tolerance test (OGTT).Results
We surveyed 470 households and included 1317 individuals. Prevalence of diabetes was 18.3% (known 10.8% and newly detected 7.5%). Prevalence of prediabetes was 21% as per WHO criteria and 39.5% as per ADA criteria. The ratio of known to unknown diabetes was 1.44:1. Every third household (35.77%) had at least one known case of diabetes. High rates of obesity and central obesity were also observed in the study population.Conclusion
The present study found a strikingly high prevalence of diabetes, prediabetes and obesity in Delhi. This calls for urgent and effective preventive measures to prevent diabetes. 相似文献12.

Individuals with diabetes develop lower extremity amputation for several reasons. Investigations into pathways to the development of complications are important both for treatment and prevention.
Aim
To evaluate the relationship between amputation and risk factors in people with diabetes mellitus.Materials and method
All participants included in this study (n = 165) were recruited from the Diabetic Foot Program, developed in a Brazilian University, over seven years (2007–2014) and all information for this study was extracted from their clinical records.Results
The prevalence of amputation in patients with diabetes with four risk factors was up to 20% higher when compared to those with only one risk factor. The main predictive risk factors for amputation in this population were the presence of an ulcer and smoking.Conclusion
The risk factors for amputation can be predicted for people with diabetes mellitus and, in the present study, the main factors were the presence of an ulcer and the smoking habit. 相似文献13.

Background
Few studies have focused on the management of secondary spontaneous pneumothorax (SSP) as a complication of pneumoconiosis. The aim of this study was to investigate the clinical features and therapeutic course of SSP associated with silicosis.Methods
Between April 2005 and March 2015, 17 patients with silicosis underwent chest tube drainage for SSP in our institution. We retrospectively analyzed patient characteristics, type of treatment, clinical course, rate of recurrence, and survival time, and compared them with those of 30 patients diagnosed with chronic obstructive pulmonary disease (COPD) during the same period.Results
Fourteen patients with silicosis had performance status score ≥ 2 and modified Medical Research Council Grade ≥ 2; these were significantly different from those in patients with COPD (P = 0.047, P = 0.026). Patients with silicosis had a significantly longer duration of chest tube placement and hospital stay. Recurrent pneumothorax occurred in 47.1% of patients with silicosis, which was not significantly different from the proportion of patients with COPD (40.9%, P = 0.843). However, in the silicosis group, patients treated with chest tube drainage alone tended to have a higher rate of ipsilateral recurrence than those who had pleurodesis, although this was not statistically significant. The median overall survival time of patients with silicosis was 82.6 months, while that of patients with COPD was 104.1 months.Conclusions
Patients with silicosis had worse physical status and respiratory functions at the time of occurrence of pneumothorax than those with COPD. Pleurodesis could be an effective treatment for SSP complicating silicosis. 相似文献14.

Background
Residents in the district struck by the Great East Japan Earthquake Tsunami (GEJET) suffered from adverse living conditions and various pulmonary diseases.Objectives
To evaluate the influence of GEJET, we performed serial assessment of pulmonary function of approximately 10,000 residents in the district struck by GEJET.Methods
Using a spirometer, we assessed the pulmonary function of approximately 10,000 residents older than 18 years in the Sanriku seacoast, which was struck by the tsunami. Measurements were performed in 2011 and 2012.Results
We compared FVC (forced vital capacity) % pred. and FEV1 (forced expiratory volume in 1 second) % pred. of subjects between 2011 and 2012, by serial spirometry. Of the 7053 subjects studied, including 2611 men and 4442 women, FVC% pred. and FEV1% pred. were significantly higher in 2012 than in 2011. Physical indices including height, body weight and the body mass index (BMI) did not change significantly during this period. Smoking prevalence changed significantly between 2010, 2011, and 2012. Both FVC% pred. and FEV1% pred. of subjects who had quit smoking increased significantly on spirometry carried out in 2012, compared with those in 2011.Conclusions
The pulmonary function expressed as FVC% pred. and FEV1% pred. were significantly higher in 2012 than in 2011 among the subjects studied. The changes in the smoking status may be one of the reasons for the increase in values observed. However, other undetermined factors during recovery from a disaster might have resulted in improved pulmonary function. 相似文献15.

Background
Chronic lung diseases are one of the leading causes of morbidity in developing countries. A community based survey was undertaken with an objective to estimate the prevalence of chronic respiratory diseases and to describe the profile of people with CRDs in the rural area Nilamel health block in Kollam district, Kerala, southern India.Methods
A household information sheet and a translated respiratory symptom questionnaire based on International Union against Tuberculosis and Lung Disease (IUATLD) bronchial symptoms questionnaire was administered to 12,556 people above 15 years, selected randomly from Nilamel health block.Results
Prevalence of self reported asthma was 2.82% (95% CI 2.52–3.12) and that of chronic bronchitis was 6.19% (95% CI 5.76–6.62) while other CRDs which did not fit to either constitute 1.89%. Prevalence of asthma among males was 2.44% (95% CI 2.05–2.85) while that of females was 3.14% (95% CI 2.71–3.57). Chronic bronchitis prevalence was 6.73% and 5.67% among males and females respectively.Conclusion
Although India has devised a programme to combat cancer, diabetes, cardio vascular disease and stroke, none have been devised for chronic respiratory illness till date. Considering high prevalence and its contributions to morbidity and mortality, a comprehensive programme to tackle chronic respiratory diseases is needed. 相似文献16.

Background
To study the relationship between chronotropic incompetence (CI) and disease severity and to assess the effect of CI on exercise capacity in patients with chronic obstructive pulmonary disease (COPD).Materials and Methods
Arterial blood gas analysis, pulmonary function test and cardiopulmonary exercise testing were conducted in 60 patients with stable COPD and 45 healthy volunteers. CI was defined using the chronotropic response index (CRI = (peak heart rate-resting heart rate) / (220-age-resting heart rate). Based on CRI, patients with COPD were divided into the normal chronotropic group (n = 23) and CI group (n = 37).Results
CI was present in 61.7% of the patients with COPD. Exercise capacity (peak oxygen uptake as percentage of predicted value, peak VO2%pred), peak heart rate and CRI were significantly lower in patients with COPD than in controls. However, resting heart rate was significantly higher than in controls. FEV1%pred and exercise capacity were significantly decreased in the CI group when compared with those in the normotropic group. There was significant association between CRI with FEV1%pred and peak VO2%pred. Multivariate regression analysis showed that CRI and FEV1%pred were independent predictors of exercise capacity in patients with COPD. A cutoff of 0.74 for the CRI showed a specificity of 94.1% in predicting patients with a peak VO2%pred < 60%.Conclusions
CRI was associated with disease severity in patients with COPD. CI may be an important parameter to reflect exercise capacity in patients with COPD. 相似文献17.

Background
Chronic obstructive pulmonary disease (COPD) and type 2 diabetes (T2DM) are common comorbidities. COPD is a known risk factor for incident T2DM, however few studies have examined the relationship in reverse. The primary aim of this study was to compare the incidence of COPD in people with and without T2DM.Materials and methods
We conducted a retrospective case-control study using a long-established English general practice network database (n = 894,646). We matched 29,217 cases of T2DM with controls, adjusting for age, gender, smoking status, BMI and social deprivation, to achieve 1:1 propensity matching and compared the rate of incident COPD over eight years of follow-up. We performed a secondary analysis to investigate the effect of insulin, metformin and sulphonylureas on COPD incidence.Results
People with T2DM had a reduced risk of COPD compared to matched controls over the follow-up period (HR 0.89, 95%CI 0.79–0.93). 48.5% of those with T2DM were ex-smokers compared with 27.3% of those without T2DM. Active smoking rates were 20.4% and 23.7% respectively. Insulin, metformin and sulphonylureas were not associated with incident COPD.Conclusions
People with T2DM are less likely to be diagnosed with COPD than matched controls. This may be due to positive lifestyle changes, such as smoking cessation in those with T2DM. 相似文献18.

Background
Inconsistent results have been described regarding the part of fetuin-A and testosterone in arterial stiffness in type 2 diabetes mellitus (T2DM).Aim
To look into the links of serum fetuin-A and testosterone levels with brachial-Ankle pulse wave velocity (baPWV), a marker of arteriosclerosis and common carotid intima media thickness (ccIMT), a marker of early atherosclerosis, in diabetic Saudi men patients.Subjects and methods
One hundred and fifty adult male patients with T2DM and 60 non-diabetic control subjects were enrolled from different Saudi Arabia Taif hospitals. Biochemical analysis, anthropometric measurements, blood pressure, baPWV and ccIMT were investigated.Results
Stepwise regression in diabetic patients revealed that the most important predictor of ba-PWV was serum fetuin-A followed by serum glucose and the most important predictor of ccIMT was serum fetuin-A followed by serum HDL then serum triglycerides.Conclusions
Only fetuin-A levels not testosterone are negatively associated with early markers of atherosclerosis. 相似文献19.

Background
Type 2 diabetes mellitus (T2DM) is a major health burden worldwide with many patients encountering thyroid dysfunction later in their life. Various studies have found that diabetes and thyroid disorders mutually influence each other and both disorders tend to coexists. However, the prevalence of thyroid dysfunction and associated clinical variables in these patients has not been investigated.Objectives
The study aimed at determining the incidence and prevalence of thyroid dysfunction in patients with T2DM in relation to age, sex, metabolic syndrome and other co-morbid conditions.Research designs & methods
In this cross-sectional study, 250 Type 2 DM patients were enrolled aged between 40 and 75 years. All the patients were evaluated for thyroid dysfunction by testing thyroid profile (T3, T4 and TSH. These subjects were also investigated for fasting blood sugar (FBS), post prandial glucose (PPG) glycosylated hemoglobin (HbA1c), serum cholesterol, serum triglycerides, high density lipoprotein (HDL), low density lipoprotein(LDL), very low density lipoprotein(VLDL), blood urea, serum creatinine and presence of other co-morbid conditions. The observations and interpretations were recorded and results obtained were statistically analyzed.Results
A high prevalence of thyroid dysfunction (28%) was observed in type 2 diabetic patients with subclinical hypothyroidism (18.8%) as the commonest thyroid disorder. Thyroid dysfunction was more prevalent in females, with presence of dyslipidemia, retinopathy, poor glycemic state (HbA1c ≥7) and longer duration of diabetes as significant contributing factors associated.Conclusions
In addition to glycemic status, screening of thyroid disorder should be routinely done in type 2 diabetic subjects along with other comorbid conditions. 相似文献20.
