Full Text Available One of effective and safe immunomodulators for prophylaxis and treatment of frequently ailing children is pidotimod (Imunorix. Efficacy of the drug in pediatric practice was studied in more than 3200 patients with acute and recurrent respiratory infections. The article shows reasonability of pidotimod administration in children with acute and chronic bronchitis. This fact was confirmed with doubleblinded placebo-controlled studies. Treatment with pidotimod results in decreased terms of recovery of chronic bronchitis exacerbation, shortening of exacerbation. Realization of stable effect is related to recovery of key functions of inborn and adaptive immunity, it begins in 15 days after intake of the drug in therapeutic dose. Prophylactic doses of pidotimod should be used during next 30–60 days.Key words: children, bronchitis, pidotimod, immunity, treatment.(Voprosy sovremennoi pediatrii — Current Pediatrics. 2010;9(6:139-143

Eighteen dogs with chronic bronchitis were studied using physiologic, radiologic, microbiologic, and pathologic techniques. Twelve of these dogs were evaluated before and after two weeks of oral bronchodilator administration. Thoracic radiographs, tidal breathing flow-volume loops, radioaerosol ventilation scans, airway appearance at bronchoscopy, and airway pathology were abnormal in the majority of dogs studied. There was a significant relationship between abnormal ventilation scans and abnormal results for PaO2 and end-tidal airflow. Bronchoscopy revealed excessive mucus and inflammation of airway mucosa in all 16 dogs undergoing this procedure. Endoscopically obtained aerobic bacterial cultures grew mixed bacterial flora in only three dogs. Increased numbers of neutrophils in 14 dogs were detected by airway lavage cytology. A large number of eosinophils were seen in airway lavages obtained from two dogs; these two dogs also had evidence for eosinophilic bronchitis on endobronchial biopsy. Oral bronchodilator administration resulted in clinical and expiratory airflow improvements in most dogs, but had no effect on PaO2 or on the radioaerosol-scan abnormalities. The presence of both the physiologic and pathologic airway abnormalities of chronic bronchitis in dogs presented to a veterinary hospital with chronic unexplained cough was confirmed, suggesting that aerobic bacteria do not play an etiologic role in most cases

Bronchial asthma is characterized by chronic airway inflammation. The primary goal of treatment of asthma is to maintain the state of control. According to the Japanese guidelines (JGL2012), long-term management consists of 4 therapeutic steps, and use of inhaled corticosteroids (ICS) is recommended at all 4 steps. Besides ICS, inhalation of long-acting β2-agonist (LABA) is also effective. Recently, omalizumab (a humanized antihuman IgE antibody) can be available for patients with severe allergic asthma. Although there is no specific strategy for preoperative treatment of patients with asthma, preoperative systemic steroid administration seemed to be effective to prevent asthma attack during anesthesia. The most common cause of chronic bronchitis is smoking. Even the respiratory function is within normal limits, perioperative management of patients with chronic bronchitis is often troublesome. The most common problem is their sputum. To minimize perioperative pulmonary complication in these patients, smoking cessation and pulmonary rehabilitation are essential. It is known that more than 1 month of smoking cessation is required to reduce perioperative respiratory complication. However, even one or two weeks of smoking cessation can decrease sputum secretion. In summary, preoperative optimization is most important to prevent respiratory complication in patients with bronchial asthma or chronic bronchitis.

Acute exacerbations in patients with chronic bronchitis are a leading cause of hospitalizations and death. Bacteria contribute significantly to such exacerbations. The aim of this review was to explore the potential role of investigational antibiotics in the treatment of these episodes. Areas covered: The available literature in PubMed database, in websites related to investigational drugs and in websites of the producing companies has been searched. The in vitro activity against pathogens involved in acute exacerbations of chronic bronchitis and the pharmacokinetic profile of antibiotics currently under development were taken into consideration for inclusion in the review. Expert opinion: Several novel antimicrobial agents have completed preclinical and Phase I studies and were well-tolerated. Further investigation is mandatory in order to evaluate their future in treatment of chronic bronchitis exacerbations and discover potential advantages compared to already approved antimicrobials.

The outcomes related to the age of onset in patients with chronic bronchitis are still unclear. Patients and methods: A retrospective study was conducted on deceased patients whose diagnosis included bronchitis from 2010 to 2016. Patients were separated into two groups according to the age of onset (Group I, age ≤50 years old; Group II, age >50 years old. Information regarding disease course, smoking history, death age, number of admissions per year, Hugh Jones Index, and self-reported comorbidities of the patients was recorded. Results: The courses of chronic cough and sputum were 33.38±7.73 years and 14.44±8.60 years in Group I and Group II, respectively (p<0.05. The death ages of Group I and Group II were 77.65±7.87 years and 84.69±6.67 years, respectively (p<0.05. There was a significant negative correlation between the number of hospital admissions per year and the age of onset. The age of onset was negatively associated with daily smoking count (r=-0.210 and total smoking count (r=-0.146. In Group I, there were fewer cases of coronary heart disease (OR =0.41 [0.24–0.71], neurological diseases (OR =0.48 [0.24–0.97], and total comorbidities (OR =0.67 [0.54–0.85] than in Group II. Conclusion: Patients with early onset chronic bronchitis had a longer history, younger death age, poorer health status, and lower incidence of comorbidities.

Full Text Available Abstract Background There is growing evidence that air pollution from traffic has adverse long-term effects on chronic respiratory disease in children, but there are few studies and more inconclusive results in adults. We examined associations between residential traffic and asthma and COPD in adults in southern Sweden. A postal questionnaire in 2000 (n = 9319, 18–77 years provided disease status, and self-reported exposure to traffic. A Geographical Information System (GIS was used to link geocoded residential addresses to a Swedish road database and an emission database for NOx. Results Living within 100 m of a road with >10 cars/minute (compared with having no heavy road within this distance was associated with prevalence of asthma diagnosis (OR = 1.40, 95% CI = 1.04–1.89, and COPD diagnosis (OR = 1.64, 95%CI = 1.11–2.4, as well as asthma and chronic bronchitis symptoms. Self-reported traffic exposure was associated with asthma diagnosis and COPD diagnosis, and with asthma symptoms. Annual average NOx was associated with COPD diagnosis and symptoms of asthma and chronic bronchitis. Conclusion Living close to traffic was associated with prevalence of asthma diagnosis, COPD diagnosis, and symptoms of asthma and bronchitis. This indicates that traffic-related air pollution has both long-term and short-term effects on chronic respiratory disease in adults, even in a region with overall low levels of air pollution.

Full Text Available Background: Although Lebanon is a highly polluted country, so far no study has specifically been designed to assess the association between outdoor air pollution and chronic bronchitis in this country. Objective: To assess the association between exposure to outdoor air pollution and chronic bronchitis in Lebanon. Methods: A pilot case-control study was conducted in two tertiary care hospitals. Cases consisted of patients diagnosed with chronic bronchitis by a pulmonologist and those epidemiologically confirmed. Controls included individuals free of any respiratory signs or symptoms. After obtaining informed consent, a standardized questionnaire was administered. Results: Bivariate, stratified (over smoking status and gender and multivariate analyses revealed that passive smoking at home (ORa: 2.56, 95% CI: 1.73–3.80 and at work (ORa: 1.89, 95% CI: 1.13–3.17; older age (ORa: 1.75, 95% CI: 1.55–2.39; lower education (ORa: 1.44, 95% CI: 1.21–1.72; living close to a busy road (ORa: 1.95, 95% CI: 1.31– 2.89 and to a local power plant (ORa: 1.62, 95% CI: 1.07–2.45; and heating home by hot air conditioning (ORa: 1.85, 95% CI: 1.00–3.43 were moderately associated with chronic bronchitis; an inverse association was found with heating home electrically (ORa: 0.58, 95% CI: 0.39–0.85. A positive dose-effect relationship was observed in those living close to a busy road and to a local diesel exhaust source. Conclusion: Chronic bronchitis is associated with outdoor air pollution.

1965-01-01

A questionnaire and lung function survey were conducted of groups of van drivers employed either in central London or in 3 rural English towns. Consistent with similar studies, urban/rural respiratory morbidity gap was prominent, even after accounting for smoking, socio-economic class, physique, and occupation. Other major variable was air pollution. Smoking exacerbated symptoms. Londoners had lower peak flow rate, lower FEV/sub 1/ /sub 0/, greater incidence of symptoms of chronic bronchitis, greater proportion of purulent sputum, and greater incidence of cough. Differences accentuated in men aged 50 and older. Differences in some variables between urban and rural areas (e.g., cough) show little effect of air pollution on non-smokers.

To study a clinical effect of fenspirid and its impact on external respiration function in patients with chronic obstructive bronchitis (COB) in the exacerbation phase. 30 COB patients participated in the trial (20 males, 10 females, age 39-80 years). The severity of clinical symptoms (cough, sputum, dyspnea) was studied using special scales. External respiration function was examined by a spirometric system "Tamrac system spiro sense Y2 14". Fenspirid treatment was conducted in a dose 80 mg twice a day for 3 months. Control examinations were made 2 weeks, 1 and 3 months after the treatment start. A 3-month treatment with fenspirid resulted in regression of COB symptoms: cough and sputum ceased, dyspnea decreased. This led to improvement in external respiration function, especially in patients with mixed ventilatory disorders with prevailing restriction. Fenspirid is an effective and well tolerated treatment of chronic obstructive bronchitis.

Risk factors beyond tobacco smoking associated with chronic bronchitis are not well understood. We sought to describe the prevalence and risk factors of chronic bronchitis across four distinct settings in Peru with overall low prevalence of tobacco smoking yet varying degrees of urbanization, daily exposure to biomass fuel smoke and living at high altitude. We analyzed data of 2,947 participants from rural and urban Puno, Lima and Tumbes including spirometry, blood samples, anthropometry and administered questionnaires about respiratory symptoms. We used multivariable Poisson regression to assess biologic, socioeconomic and environmental risk factors associated with chronic bronchitis. Overall prevalence of chronic bronchitis was 5.9% (95%CI 5.1%-6.9%) with variation by setting: prevalence was lower in semi-urban Tumbes (1.3%) vs. highly urbanized Lima (8.9%), urban Puno (7.0%) and rural Puno (7.8%; p urbanization (PR = 3.34, 95%CI 2.18-5.11) and daily exposure to biomass fuel smoke (PR = 2.00, 95%CI 1.30-3.07) were all associated with chronic bronchitis. We found important variations in the prevalence of chronic bronchitis across settings. Prevalence increased with both urbanization and with daily exposure to biomass fuel smoke. Having chronic bronchitis was also associated with worse patient-centered outcomes including dyspnea, hospitalization and missed workdays.

In order to observe the changes in thromboxane B 2 (TXB 2 ) and 6-keto-prostaglandin F 1α (6-K-PGF 1α ) levels in bronchial asthma, asthmatic chronic bronchitis as well as simple chronic bronchitis, the TXB 2 and 6-K-PGF 1α levels in plasma and broncho-alveolar lavage fluid (BALF) for control and patients with bronchial asthma, asthmatic chronic bronchitis and simple chronic bronchitis, 30 in each group, were measured by radioimmunoassay. The results showed that the TXB 2 and 6-K-PGF 1α levels in plasma and BALF in patients of the three groups increased and those in patients with bronchial asthma increased markedly with significant difference, as compared with those in patients with chronic bronchitis (P 2 and 6-K-PGF 1α levels in BALF in patients with asthmatic chronic bronchitis were much higher than those in patients with simple chronic bronchitis (P 2 and 6-K-PGF 1α play an important role in pathogenesis of bronchial asthma and asthmatic chronic bronchitis. Consequently, the changes of the two parameters in BALF provide certain reference basis for differential diagnosis of the two types of chronic bronchitis

Full Text Available The global prevalence of physiologically defined chronic obstructive pulmonary disease (COPD in adults aged >40 yr is approximately 9-10 per cent. Recently, the Indian Study on Epidemiology of Asthma, Respiratory Symptoms and Chronic Bronchitis in Adults had shown that the overall prevalence of chronic bronchitis in adults >35 yr is 3.49 per cent. The development of COPD is multifactorial and the risk factors of COPD include genetic and environmental factors. Pathological changes in COPD are observed in central airways, small airways and alveolar space. The proposed pathogenesis of COPD includes proteinase-antiproteinase hypothesis, immunological mechanisms, oxidant-antioxidant balance, systemic inflammation, apoptosis and ineffective repair. Airflow limitation in COPD is defined as a postbronchodilator FEV1 (forced expiratory volume in 1 sec to FVC (forced vital capacity ratio <0.70. COPD is characterized by an accelerated decline in FEV1. Co morbidities associated with COPD are cardiovascular disorders (coronary artery disease and chronic heart failure, hypertension, metabolic diseases (diabetes mellitus, metabolic syndrome and obesity, bone disease (osteoporosis and osteopenia, stroke, lung cancer, cachexia, skeletal muscle weakness, anaemia, depression and cognitive decline. The assessment of COPD is required to determine the severity of the disease, its impact on the health status and the risk of future events (e.g., exacerbations, hospital admissions or death and this is essential to guide therapy. COPD is treated with inhaled bronchodilators, inhaled corticosteroids, oral theophylline and oral phosphodiesterase-4 inhibitor. Non pharmacological treatment of COPD includes smoking cessation, pulmonary rehabilitation and nutritional support. Lung volume reduction surgery and lung transplantation are advised in selected severe patients. Global strategy for the diagnosis, management and prevention of Chronic Obstructive Pulmonary Disease

Background: Several studies highlighted a great variability, both between and within countries, in the prevalence of asthma and chronic airways diseases. Aim: To evaluate if geo-climatic variations can explain the heterogeneity in the prevalence of asthma and respiratory diseases in Italy. Methods: Between 2006 and 2010, a postal screening questionnaire on respiratory health was administered to 18,357 randomly selected subjects, aged 20–44, living in 7 centers in northern, central, and southern Italy. A random-effects meta-analysis was fitted to evaluate the between-centers heterogeneity in the prevalence of asthma, asthma-like symptoms, allergic rhinitis, and chronic bronchitis (CB). A principal component analysis (PCA) was performed to synthetize the geo-climatic information (annual mean temperature, range of temperature, annual rainfalls, global solar radiations, altitude, distance from the sea) of all the 110 Italian province capital towns. The associations between these geo-climatic components obtained with PCA and the prevalence of respiratory diseases were analyzed through meta-regression models. Results: 10,464 (57%) subjects responded to the questionnaire. There was a significant between-centers heterogeneity in the prevalence of asthma (I"2 = 59.5%, p = 0.022) and CB (I"2 = 60.5%, p = 0.019), but not in that of asthma-like symptoms or allergic rhinitis. Two independent geo-climatic components explaining together about 80% of the overall geo-climatic variability were identified: the first principally summarized the climatic variables; the second the topographic ones. Variations in the prevalence of asthma across centers were significantly associated with differences in the climatic component (p = 0.017), but not with differences in the topographic one. Conclusions: Our findings suggest that climate play a role in determining the between-center heterogeneity in the prevalence of asthma in Italy, with higher prevalence in dry-hot Mediterranean climates

In a 2-year longitudinal study of boilermaker construction workers, authors found a significant association between working at oil-fired, coal-fired, and gas-fired industries during the past year and reduced lung function. In the present study, authors investigated whether chronic bronchitis, asthma, or baseline methacholine airway responsiveness can explain the heterogeneity in lung function response to boilermaker work. Exposure was assessed with a work history questionnaire. Spirometry was performed annually to assess lung function. A generalized estimating equation approach was used to account for the repeated-measures design. One hundred eighteen boilermakers participated in the study. Self-reported history of chronic bronchitis and asthma were associated with a larger FEV1 reduction in response to workplace exposure at coal-fired and gas-fired industries. Although a high prevalence (39%) of airway hyperresponsiveness (provocative concentration of methacholine causing a 20% fall in FEVI of {lt} 8 mg/mL) among boilermakers was found, there was no consistent pattern of effect modification by airway responsiveness. Conclusions: Although chronic bronchitis and asthma were associated with a greater loss in lung function in response to hours worked as a boilermaker, and therefore they acted as effect modifiers of the exposure-lung function relationship, airway hyperresponsiveness did not. However, the high prevalence of airway hyperresponsiveness found in the cohort may be a primary consequence of long-term workplace exposure among boilermakers.

To study bronchial reactivity and sensitivity with consideration of histamine, serotonin and catecholamines concentration in bronchial mucosa in patients with acute bronchitis (AB) as possible criteria of its becoming chronic. Before the treatment 116 patients with verified AB were examined using inhalation provocative tests (IPT) with histamine, serotonin and obsidian in increasing doses. Also, external respiration function was studied. IPT were repeated after the course of treatment. 87 of 116 AB patients exhibited high bronchial sensitivity and reactivity to inhalations of histamine, serotonin, obsidian. In parallel, there was a rise in the levels of histamine and serotonin and a fall in the level of catecholamines in bronchial mucosa (alveolar macrophages, lymphocytes, neutrophils, mast and APUD-cells). Changes in monoamines concentration in bronchial mucosa were relevant to activity of bronchial inflammation and the presence of obstructive syndrome. Persistent bronchial hyperreactivity to inhalations of histamine and obsidian along with high histamine levels and low level of catecholamines in alveolar macrophages, lymphocytes and mucus is a criterion of bronchitis transformation to chronic one.

This study was performed to estimate the strength of association between chronic bronchitis and lifetime exposure to occupational factors, current lifestyle, and the NS-phenotype in the MNS blood group among middle aged and elderly men. The study was carried out within the frameworks of the Copenhagen Male Study. Of 3387 men 3331 men with a mean age of 63 (range 53-75) years could be classified by prevalence of chronic bronchitis. As well as the completion of a large questionnaire on health, lifestyle, and working conditions, all participants had a thorough examination, including measurements of height and weight and blood pressure and a venous blood sample was taken for the measurement of serum cotinine and MNS typing; 16.5% of the men had the NS-phenotype. Chronic bronchitis was defined as cough and phlegm lasting 3 months or more for at least 2 years; 14.6% had chronic bronchitis. Smoking and smoke inhalation were the factors most strongly associated with prevalence of chronic bronchitis. There were three major new findings: (a) long term (>5 years) occupational exposure to cold and draught was associated with a significantly increased prevalence of chronic bronchitis; compared with others, and adjusted for confounders, the odds ratio (OR) with 95% confidence interval (95% CI) was 1.4 (1.1 to 1.7), p=0.004; (b) a significant J shaped association existed between alcohol use and bronchitis, pdraught exposure, alcohol consumption, and the NS-phenotype and chronic bronchitis.

A study of the social, socioeconomic and economic indices of rehabilitation of patients with chronic obstructive and nonobstructive bronchitis has shown that one should take account of a degree of expression of heliometeolability when selecting patients with chronic bronchitis residing in West Siberia for climatic treatment in the Crimean South Coast. It has been shown that rehabilitation in the Crimean South Coast health resort area is advisable for heliometeostable patients and patients with mild and marked degrees of heliometeolability. Patients with chronic bronchitis should not be sent to the Crimea in winter and late autumn as the rehabilitation effect in this period is lowered.

Chronic obstructive pulmonary disease

International Nuclear Information System (INIS)

Full text: Chronic obstructive pulmonary diseases (COPD) denote progressive lung diseases characterized by airway obstruction. COPD exhibits specific morphologic changes in the lung parenchyma, central and peripheral airways and pulmonary vasculature. A person with COPD may have either emphysema or chronic bronchitis, but most have both. Some people with COPD may also have an asthma-like or reactive component. Imaging modalities play important role in the detection or exclusion of COPD, distribution and extent of disease processes. Combined inspiratory and expiratory high resolution CT allows phenotyping of COPD (emphysema predominant, airway predominant, or mixed) and quantification of severity. Magnetic resonance imaging enables functional evaluation and demonstrates ventilation defects correlating closely with pulmonary function tests. Imaging techniques are also helpful in guiding the treatment, such as bullectomy in patients with bullous emphysema, lung volume reduction surgery or endoscopic interventions in those with severe emphysema, and smoking cessation and medical treatment designed to stop lung destruction in patients with mild or moderate emphysema or bronchiectasis.

Cordyceps guangdongensis T. H. Li, Q. Y. Lin & B. Song (Cordycipitaceae) is a novel food approved by the Ministry of Public Health of China in 2013. Preliminary studies revealed that this novel food has multiple pharmacological activities such as anti-fatigue effect, antioxidant ability, prolonging life, anti-avian influenza virus activity, and therapeutic effect on chronic renal failure. However, the anti-inflammatory effect on chronic bronchitis and the effective constituent are still unknown. The purpose of this study was to investigate both the anti-inflammatory effect of the edible fungus on experimental rats with chronic bronchitis induced by tobacco smoking, and the pilot effective constituent. Test rats were intragastrically administered with 3 doses of hot-water extract from C. guangdongensis (0.325, 0.65 and 1.30 g kg(-1) bw daily for low, middle and high dose, respectively) for 26 days. Biochemical indices and histological examinations in rats with chronic bronchitis induced by tobacco smoking were determined. The content and molecular weights of the polysaccharide from the hot-water extract were detected by the phenol-sulfuric acid method and gel permeation chromatography, respectively. Biochemical indices in the low, middle and high-dose groups with the hot-water extract of C. guangdongensis were only 53.4%, 46.0% and 40.4% of those in the model control group (total leukocytes), respectively; 70.7%, 60.3% and 58.1% (macrophages); 33.0%, 26.8% and 16.1% (neutrophils); and 22.2%, 23.5% and 13.6% (lymphocytes) of those in the model control group. The bronchial lesions and inflammatory cell infiltration were significantly alleviated in all groups with hot-water extract of C. guangdongensis. This study indicates that the hot-water extract from C. guangdongensis has a significant anti-inflammatory effect on chronic bronchitis. The content of the polysaccharide was 6.92%; the molecular weights of the 3 polysaccharide components were respectively 1.28 × 10

Full Text Available Abstract Background Acute exacerbations of chronic bronchitis (AECB, including chronic obstructive pulmonary disease (AECOPD, represent a substantial patient burden. Few data exist on outpatient antibiotic management for AECB/AECOPD in Eastern/South Eastern Europe, in particular on the use of moxifloxacin (Avelox®, although moxifloxacin is widely approved in this region based on evidence from international clinical studies. Methods AVANTI (AVelox® in Acute Exacerbations of chroNic bronchiTIs was a prospective, observational study conducted in eight Eastern European countries in patients > 35 years with AECB/AECOPD to whom moxifloxacin was prescribed. In addition to safety and efficacy outcomes, data on risk factors and the impact of exacerbation on daily life were collected. Results In the efficacy population (N = 2536, chronic bronchitis had been prevalent for > 10 years in 31.4% of patients and 66.0% of patients had concomitant COPD. Almost half the patients had never smoked, in contrast to data from Western Europe and the USA, where only one-quarter of COPD patients are non-smokers. The mean number of exacerbations in the last 12 months was 2.7 and 26.3% of patients had been hospitalized at least once for exacerbation. Physician compliance with the recommended moxifloxacin dose (400 mg once daily was 99.6%. The mean duration of moxifloxacin therapy for the current exacerbation (Anthonisen type I or II in 83.1%; predominantly type I was 6.4 ± 1.9 days. Symptom improvement was reported after a mean of 3.4 ± 1.4 days. After 5 days, 93.2% of patients reported improvement and, in total, 93.5% of patients were symptom-free after 10 days. In the safety population (N = 2672, 57 (2.3% patients had treatment-emergent adverse events (TEAEs and 4 (0.15% had serious TEAEs; no deaths occurred. These results are in line with the known safety profile of moxifloxacin. Conclusions A significant number of patients in this

Given the wide variations in prevalence of chronic obstructive pulmonary disease observed between populations with similar levels of exposure to tobacco smoke, we aimed to investigate the possibility of variations in prevalence of chronic bronchitis (CB) between two geographically distinct smoking populations in rural Karnataka, India. The Burden of Obstructive Lung Disease (BOLD) questionnaire was administered to all men aged >30 years in a cross-sectional survey. The χ(2) and Fisher's exact tests were used to compare CB prevalence in the two populations. Logistic regression was used to analyse the impact of multiple variables on the occurrence of CB. Two samples of 2322 and 2182 subjects were included in the study. In non-smokers, CB prevalence did not differ between the populations. However, it was significantly different between smoking populations (44.79% vs. 2.13%, P < 0.0001). Logistic regression indicated that, in addition to smoking, region, age, occupational dust exposure and type of house were associated with higher likelihood of CB. An interaction between smoking and area of residence was found (P < 0.001) and appeared to explain the effect of region (without interaction). A significant difference in CB prevalence was observed between male populations from two areas of Karnataka state, including when stratified by smoking status. No significant difference was observed between non-smokers.

BACKGROUND: There is limited knowledge concerning chronic bronchitis (CB) in Canadian Aboriginal peoples. OBJECTIVE: To determine the prevalence (crude and adjusted) of CB and its associated risk factors in Canadian Aboriginal children and youth six to 14 years of age. METHODS: Data from the cross-sectional Aboriginal Peoples Survey were analyzed in the present study. Logistic regression analysis was used to determine risk factors influencing the prevalence of CB among Aboriginal children and youth. The balanced repeated replication method was used to compute standard errors of regression coefficients to account for clustering inherent in the study design. The outcome of interest was based on the question: “Have you been told by a doctor, nurse or other health professional that you have chronic bronchitis?” Demographics, environment and population characteristics (predisposing and enabling resources) were tested for an association with CB. RESULTS: The prevalence of CB was 3.1% for boys and 2.8% for girls. Other significant risk factors of CB were age (OR 1.38 [95% CI 1.24 to 1.52] for 12 to 14 year olds versus six to eight year olds), income (OR 2.28 [95% CI 2.02 to 2.59] for income category <$25,000/year versus ≥$85,000/year), allergies (OR 1.96 [95% CI 1.78 to 2.16] for having allergies versus no allergies), asthma (OR 7.61 [ 95% CI 6.91 to 8.37] for having asthma versus no asthma) and location of residence (rural/urban and geographical location). A significant two-way interaction between sex and body mass index indicated that the relationship between the prevalence of CB and body mass index was modified by sex. DISCUSSION: The prevalence of CB was related to well-known risk factors among adults, including older age and lower annual income. PMID:23248806

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. 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. 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. 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.

A Rare Case of Idiopathic Plastic Bronchitis

2017-01-01

Full Text Available Plastic bronchitis is a rare disorder characterized by formation of large, branching bronchial casts, which are often expectorated. We present an interesting case of a 35-year-old woman who presented for evaluation of a chronic cough productive of voluminous secretions. Clinical and radiological examination confirmed a total left lung atelectasis without any pathological mediastinal node. Flexible bronchoscopy demonstrated tenacious, thick, and sticky whitish secretions blocking the left stem bronchus. This material was extracted, and inspection demonstrated a bronchial cast, whose pathological analysis revealed necrotic epithelial cells, some eosinophils, and Charcot-Leyden crystals. Two days after bronchoscopy, the patient rejected more bronchial casts, and dyspnea improved. Control of chest x-ray revealed complete left lung aeration and the diagnosis of idiopathic plastic bronchitis was obtained. This article shows the interest in clinical practice to evoke the diagnosis of plastic bronchitis in front of a productive chronic cough. Our case illustrates a rare clinical presentation represented by an atelectasis of an entire lung.

Lung disease with chronic obstruction in opium smokers in Singapore

Fifty-four opium smokers with chronic obstructive lung disease were studied for two-and-a-half years. Forty-eight patients had a cough for at least two years before the onset of inappropriate exertional dyspnoea. Fine, bubbling adventitious sounds suggesting small airway disease were heard on auscultation over the middle and lower lobes in 38 patients. The prevalence of inflammatory lung disease and chronic respiratory failure in this series is suggested as the main cause for the frequent finding of right ventricular hypertrophy and congestive heart failure. Physiological studies revealed moderate to severe airways obstruction with gross over-inflation and, in 32 patients, an additional restrictive defect probably due to peribronchiolar fibrosis. Radiological evidence of chronic bronchitis and bronchiolitis was observed in 45 patients, `pure' chronic bronchiolitis in six patients, and `widespread' emphysema in 25 patients respectively. Necropsy examinations in nine patients, however, showed destructive emphysema of variable severity in all. Chronic bronchiolitis often associated with striking bronchiolectasis was present in six cases. More severe bronchiolar rather than bronchial inflammation was noted. The heavy opium smokers had characteristic nodular shadows on chest radiography, sometimes associated with a striking reticular pattern not seen in `pure' cigarette smokers. This was due to gross pigmented dust (presumably carbon) deposition in relation to blood vessels, lymphatics, and bronchioles, and also within the alveoli. It is speculated that the initial lesion is an acquired bronchiolitis. Opium smoking induces an irritative bronchopathy favouring repeated attacks of acute bronchiolitis and eventually resulting in obliterative bronchiolitis, peribronchiolar fibrosis, chronic bronchitis, and destructive emphysema.

Chronic obstructive pulmonary disease (COPD) is divided into pulmonary emphysema and chronic bronchitis (CB). Emphysema is defined patho-anatomically as "permanent enlargement of airspaces distal to the terminal bronchiole, accompanied by the destruction of their walls, and without obvious fibrosis" (1). These lesions are readily identified and quantitated using computed tomography (CT), whereas the accompanying hyperinflation is best detected on plain chest X-ray, especially in advanced disease. The diagnosis of CB is clinical and relies on the presence of productive cough for 3 months in 2 or more successive years. The pathological changes of mucosal inflammation and bronchial wall thickening have been more difficult to identify with available imaging techniques. However, recent studies using Multi-detector row CT (MDCT) reported more reproducible assessment of air wall thickening.

The Nature and Causes of Chronic Obstructive Pulmonary Disease: A Historical Perspective

Directory of Open Access Journals (Sweden)

C Peter W Warren

2009-01-01

Full Text Available Chronic obstructive pulmonary disease (COPD is the currently favoured name for the diseases formerly known as emphysema and bronchitis. COPD has been recognized for more than 200 years. Its cardinal symptoms are cough, phlegm and dyspnea, and its pathology is characterized by enlarged airspaces and obstructed airways. In the 19th century, the diagnosis of COPD depended on its symptoms and signs of a hyperinflated chest, and reduced expiratory breath sounds. The airflow obstruction evident on spirometry was identified in that century, but did not enter into clinical practice. Bronchitis, and the mechanical forces required to overcome its obstruction, was believed to be responsible for emphysema, although the inflammation present was recognized. The causes of bronchitis, and hence emphysema, included atmospheric and domestic air pollution, as well as dusty occupations. Cigarette smoking only became recognized as the dominant cause in the 20th century. The lessons learned of the risks for COPD in 19th-century Britain are very pertinent to the world today.

Due to contradictory literature we have performed a systematic review and meta-analyse of population-based studies that have used Job Exposure Matrices to assess occupational exposure and risk of Chronic Obstructive Pulmonary Disease (COPD). Two researchers independently searched databases for published articles using predefined inclusion criteria. Study quality was assessed, and results pooled for COPD and chronic bronchitis for exposure to biological dust, mineral dust, and gases/fumes using a fixed and random effect model. Five studies met predetermined inclusion criteria. The meta-analysis showed low exposure to mineral dust, and high exposure to gases/fumes were associated with an increased risk of COPD. We also found significantly increased the risk of chronic bronchitis for low and high exposure to biological dust and mineral dust. Expert commentary: The relationship between occupational exposure assessed by the JEM and the risk of COPD and chronic bronchitis shows significant association with occupational exposure. However, the heterogeneity of the meta-analyses suggests more wide population-based studies with older age groups and longitudinal phenotype assessment of COPD to clarify the role of occupational exposure to COPD risk.

Differential diagnosis of recurrent bronchitis in children

Full Text Available The interest of the doctors — pediatricians to recurrent bronchitis is caused by its high specific weight in the structure of bronchopulmonary pathology in children, the complexity and the need to search the differential selection of an individual regimen and prevention. Recurrent bronchitis with bronchoobstructive syndromes patient is regarded as a predictor of asthma, however, erroneously consider these nosological forms as the stages of a single pathophysiological chain as congenital and acquired diseases of respiratory system, pathology of gastro-intestinal tract, cardio-vascular system can masquerade as recurrent bronchitis. The aim of this work — to analyze the current medical literature on the problem of differential search causes leading recurrent respiratory syndrome in children. Materials and methods. The review publications domestic and foreign authors studied data from clinical and epidemiological studies. Results and its discussion. Anatomical physiological characteristics of the respiratory tract, complicated premorbid background, the re-infection of the child respiratory infection contribute to the recurrent course of bronchitis. The most common recurrent bronchitis is transient, recurrent bronchitis episodes completely stoped with the age of the child. Recurrent respiratory infections can fix bronchial hyperreactivity and with the presence of aggravated allergic history lead to the development of asthma. Severe bronchitis, resistance to standard scheme of therapy, the frequent recurrence of respiratory syndrome dictate the need to expand the diagnostic research to clarify the leading cause of recurrent bronchitis. Conclusion. Recurrent bronchitis is considered as a separate nosological form. At the same time, by repeated episodes of respiratory infection may be masked by malformations, hereditary diseases of respiratory system, bronchus foreign body microaspiration syndrome, pathology of the cardio-vascular system.

Pohl-Boskamp GmbH & Co KG, Hohenlockstedt, Germany Background: Treating symptoms and preventing exacerbations are key components of chronic obstructive pulmonary disease (COPD long-term management. Recently, a more tailored treatment approach has been proposed, in particular for two well-established clinical phenotypes, frequent exacerbators and chronic bronchitis-dominant COPD. ELOM-080 has demonstrated clinical efficacy in treating symptoms and preventing exacerbations in subjects with chronic bronchitis. However, little is known about the potential effects of ELOM-080 in COPD patients. Aim: To evaluate the effect on exacerbation, cough sputum, and general state of health of long-term treatment with ELOM-080 in COPD patients with an exacerbation history and chronic bronchitis. Methods: We performed a post-hoc analysis of a randomized, double-blinded, placebo-controlled parallel-group clinical trial of a 6-month treatment with ELOM-080 (3×300 mg in patients with chronic bronchitis and concomitant COPD. The primary outcome was the proportion of subjects with at least one exacerbation over the 6-month study period. Secondary outcomes included the total number of exacerbations (ie, cumulative occurrence of exacerbations during the study period and the proportion of acute exacerbations necessitating an antibiotic treatment, monthly evaluations of sputum and cough symptoms, and the general state of health and a safety analysis. Results: Of 260 randomized subjects, 64 patients fulfilled the inclusion criteria for COPD (ELOM-080: 35, placebo: 29. Compared to placebo, ELOM-080 reduced the percentage of subjects with at least one exacerbation (29% versus 55%, P=0.031 and a reduction in the overall occurrence of exacerbations (ELOM-080: 10, placebo: 21, P=0.012 during the winter season.

1983-10-01

Acupuncture is an effective therapy for treatment of dust-induced bronchitis. It can be used independently or in combination with medicaments. Fifty men were divided into two groups of 20 and 30. One group was treated by acupuncture alone, the other with combined therapy. Acupuncture produced excellent results; combined treatment, good and satisfactory results. Since acupuncture reduced the possibility of complications, allergic reactions and side effects due to medication, it is an excellent means of preventing progress of dust-induced bronchitis. Patients experience 9 months remission of symptoms after treatment with acupuncture while medical therapy alone only relieves them for 1 to 1 1/2 months. Patients with chronic dust-induced bronchitis should receive a second course of acupuncture in 6 to 8 months to prevent recurrence of symptoms and progress of disease. Because of insufficient study of lasting effects of acupuncture, final conclusions about its effectiveness cannot be made, however, current evidence indicates it is a highly useful therapy. 6 references.

For decades in China, the Yin-Huang-Qing-Fei capsule (YHQFC) has been widely used in the treatment of chronic bronchitis, with good curative effects. Owing to the complexity of traditional Chinese herbal formulas, the pharmacological mechanism of YHQFC remains unclear. To address this problem, a network pharmacology-based strategy was proposed in this study. At first, the putative target profile of YHQFC was predicted using MedChem Studio, based on structural and functional similarities of all available YHQFC components to the known drugs obtained from the DrugBank database. Then, an interaction network was constructed using links between putative YHQFC targets and known therapeutic targets of chronic bronchitis. Following the calculation of four topological features (degree, betweenness, closeness, and coreness) of each node in the network, 475 major putative targets of YHQFC and their topological importance were identified. In addition, a pathway enrichment analysis based on the Kyoto Encyclopedia of Genes and Genomes pathway database indicated that the major putative targets of YHQFC are significantly associated with various pathways involved in anti-inflammation processes, immune responses, and pathological changes caused by asthma. More interestingly, eight major putative targets of YHQFC (interleukin [IL]-3, IL-4, IL-5, IL-10, IL-13, FCER1G, CCL11, and EPX) were demonstrated to be associated with the inflammatory process that occurs during the progression of asthma. Finally, a molecular docking simulation was performed and the results exhibited that 17 pairs of chemical components and candidate YHQFC targets involved in asthma pathway had strong binding efficiencies. In conclusion, this network pharmacology-based investigation revealed that YHQFC may attenuate the inflammatory reaction of chronic bronchitis by regulating its candidate targets, which may be implicated in the major pathological processes of the asthma pathway.

Cohort studies suggest that airflow obstruction is established early in life, manifests as childhood asthma and wheezy bronchitis, and continues into early adulthood. Although an association between childhood asthma and chronic obstructive pulmonary disease (COPD) in later life has been demonstrated, it is unclear if childhood wheezy bronchitis is associated with COPD. To investigate whether childhood wheezy bronchitis increases the risk of COPD in the seventh decade. A cohort of children recruited in 1964 at age 10 to 15 years, which was followed up in 1989, 1995, and 2001, was followed up again in 2014 when at age 60 to 65 years. Discrete time-to-event and linear mixed effects models were used. FEV1 and FVC were measured. COPD was defined as post-bronchodilator FEV1/FVC Childhood wheezing phenotype was related to 1989, 1995, 2001, and 2014 spirometry data. Three hundred thirty subjects, mean age 61 years, were followed up: 38 with childhood asthma; 53 with childhood wheezy bronchitis; and 239 control subjects (of whom 57 developed adulthood-onset wheeze between ages 16 and 46 yr). In adjusted multivariate analyses, childhood asthma was associated with an increased risk of COPD (odds ratio, 6.37; 95% confidence interval, 3.73-10.94), as was childhood wheezy bronchitis (odd ratio 1.81; 95% confidence interval, 1.12-2.91). The COPD risk increased with childhood asthma, and wheezy bronchitis was associated with reduced FEV1 that was evident by the fifth decade and not an accelerated rate of FEV1 decline. In contrast, adulthood-onset wheeze was associated with accelerated FEV1 decline. Childhood wheezy bronchitis and asthma are associated with an increased risk of COPD and reduced ventilatory function.

Investigation is conducted to examine effectiveness of sanatorial-climatic treatment of patients with pneumoconiosis and dust-induced bronchitis while including aerophytotherapy. Patients with both lung diseases received sanatorial, gymnastic and climatic procedures. Experimental group also received aerophytotherapy - inhalation of ester oils of lavender, anise, mint, and salvia in form of spray corresponding to their molecular composition in air. Control group did not receive aerophytotherapy. Tables present results of experiment showing changes in parameters of external breathing in patients with pneumoconiosis and in patients with dust-induced bronchitis. Tables show greater improvement in characteristics of external breathing of patients treated with inclusion of aerophytotherapy and confirm effectiveness of combined sanatorial-climatic treatment with aerophytotherapy. Patients with chronic bronchitis also experienced reduction of bronchospasm and improvement in bronchial passability. Method does not require special equipment and is economical. 9 refs.

The objective of this randomised, nonblind study was to assess the efficacy of fenspiride as complementary anti-inflammatory therapy in combination with ipratropium bromide in patients with chronic bronchitis (CB). A comparison was made with ipratropium bromide alone, the generally accepted standard therapy for CB. The study population comprised 20 patients with chronic obstructive bronchitis (COB) and 60 patients without signs of obstruction. Fifty-one males (64%) and 29 females (36%) aged from 25 to 65 years were studied over a 6-month treatment period. Combined therapy with fenspiride (160 mg/day) and ipratropium bromide (160 mug/day) was prescribed to 39 patients (28 with CB and 11 with COB) for 6 months, and monotherapy with ipratropium bromide (160 microg/day) was prescribed for 41 patients (32 with CB and nine with COB). The combined therapy group had a reduced intensity of dyspnoea, improvements in sputum nature and quantity of exudation, and a reduced intensity of coughing. The monotherapy group showed reductions in sputum exudation and cough intensity. Improvements in lung respiratory function were observed in both groups, but were greater in the combined therapy group of patients. Reduced cytosis, percentage and absolute content of neutrophils, and absolute content of lymphocytes and eosinophils in induced sputum were observed with CB patients in the combined therapy group. A reduced content of lymphocytes and an increase in macrophages were observed with CB patients in the monotherapy group. A significant decline in tumour necrosis factor (TNF)-alpha content in sputum was observed with both therapeutic regimens, although a statistically significant decline in serum TNFalpha (10.85 ng/L to 5.58 ng/L; p = 0.03) and reduced interleukin-8 in sputum (311.94 ng/L to 122.02 ng/L; p = 0.027) were observed with patients given combined therapy. The study showed greater efficacy of long-term treatment with fenspiride and ipratropium bromide compared with

To characterize the medical history, disease progression, and treatment of current-era patients with the rare diseases Fontan-associated protein-losing enteropathy (PLE) and plastic bronchitis. A novel survey that queried demographics, medical details, and treatment information was piloted and placed online via a Facebook portal, allowing social media to power the study. Participation regardless of PLE or plastic bronchitis diagnosis was allowed. Case control analyses compared patients with PLE and plastic bronchitis with uncomplicated control patients receiving the Fontan procedure. The survey was completed by 671 subjects, including 76 with PLE, 46 with plastic bronchitis, and 7 with both. Median PLE diagnosis was 2.5 years post-Fontan. Hospitalization for PLE occurred in 71% with 41% hospitalized ≥ 3 times. Therapy varied significantly. Patients with PLE more commonly had hypoplastic left ventricle (62% vs 44% control; OR 2.81, 95% CI 1.43-5.53), chylothorax (66% vs 41%; OR 2.96, CI 1.65-5.31), and cardiothoracic surgery in addition to staged palliation (17% vs 5%; OR 4.27, CI 1.63-11.20). Median plastic bronchitis diagnosis was 2 years post-Fontan. Hospitalization for plastic bronchitis occurred in 91% with 61% hospitalized ≥ 3 times. Therapy was very diverse. Patients with plastic bronchitis more commonly had chylothorax at any surgery (72% vs 51%; OR 2.47, CI 1.20-5.08) and seasonal allergies (52% vs 36%; OR 1.98, CI 1.01-3.89). Patient-specific factors are associated with diagnoses of PLE or plastic bronchitis. Treatment strategies are diverse without clear patterns. These results provide a foundation upon which to design future therapeutic studies and identify a clear need for forming consensus approaches to treatment. Copyright © 2015 Elsevier Inc.

Clinical significance of the infection-free interval in the management of acute bacterial exacerbations of chronic bronchitis.

Science.gov (United States)

Chodosh, Sanford

2005-06-01

Rational and appropriate antibiotic use for patients with acute exacerbation of chronic bronchitis (AECB) is a major concern, as approximately half of these patients do not have a bacterial infection. Typically, the result of antimicrobial therapy for patients with acute bacterial exacerbation of chronic bronchitis (ABECB) is not eradication of the pathogen but resolution of the acute symptoms. However, the length of time before the next bacterial exacerbation can be another important variable, as the frequency of exacerbations will affect the overall health of the patient and the rate of lung deterioration over time. Clinical trials comparing antimicrobial therapies commonly measure resolution of symptoms in AECB patients as the primary end point, regardless of whether the exacerbation is documented as bacterial in nature. Ideally, the scientific approach to assessing the efficacy of antibiotic therapy for ABECB should include a measurement of acute bacterial eradication rates in patients with documented bronchial bacterial infection followed by measurement of the infection-free interval (IFI), ie, the time to the next ABECB. The use of these variables can provide a standard for comparing various antimicrobial therapies. As we learn more about how antibiotics can affect the IFI, treatment decisions should be adapted to ensure optimal management of ABECB for the long-term.

Fenspiride is an anti-inflammatory drug that may have a role in inhibition of histamine receptor H1 and influence a production of archidonic acid metabolites. The efficacy and tolerance of fenspiride therapy have been performed in patients with acute bronchitis. 597 patients, 51% females and 49% males, aged 39+/-18 years, were observed because of acute bronchitis. Fenspiride (Eurespal, Servier) was given in a dose of 240 mg per day (80 mg three times daily) for 14 consecutive days. During two following medical examinations - after 7 and 14 days of treatment, clinical symptoms of disease, therapy efficacy and tolerance were determined. Mean duration of acute bronchitis before fenspiride therapy was 2.3+/-1.3 days. In most of the patients (72%) a moderate, and in 27% mild degree of disease was diagnosed. Only 1% of patients were diagnosed as severe. Total evaluation of fenspiride efficacy in examined patients with acute bronchitis showed complete relief of symptoms after 7 days of therapy in 24% and after 14 days in 87% of patients. In 6% of patients after 7 days and in 1% after 14 days of fenspiride therapy no improvement was obtained. 28 adverse reactions were determined in 26 patients (4.3%): vertigo in 7, nausea in 6, somnolence in 5, palpitations in 4, fatigue in 2, abdominal pain in 2 and other symptoms in 2 patients. In 8 patients the therapy was discontinued after 7 days because of adverse reactions. In performed observations in patients with acute bronchitis the high clinical efficacy of fenspiride therapy. In 12% of patients an antibiotic support was necessary to obtain relief of the symptoms. Very good tolerance of the 14 days therapy was determined and it is recommended for safe clinical application.

To examine chronic disease disparities by sexual orientation measurement among sexual minorities. We pooled data from the 2009-2014 National Health and Nutrition Examination Survey to examine differences in chronic disease prevalence between heterosexual and sexual minority people as defined by sexual identity, lifetime sexual behavior, 12-month sexual behavior, and concordance of lifetime sexual behavior and sexual identity. Self-identified lesbian women reported greater odds of asthma (adjusted odds ratio [aOR], 3.19; 95% confidence intervals [CI], 1.37-7.47) and chronic bronchitis (aOR, 2.64; 95% CI, 1.21-5.72) than self-identified heterosexual women. Self-identified sexual minority women with a history of same-sex sexual behavior reported greater odds of arthritis (aOR, 1.67; 95% CI, 1.02-2.74). Compared with heterosexual men, gay men reported greater odds of chronic bronchitis when sexual orientation was defined by sexual identity (aOR, 4.68; 95% CI, 1.90-11.56) or 12-month sexual behavior (aOR, 3.22; 95% CI, 1.27-8.20), as did bisexual men defined by lifetime sexual behavior (aOR, 2.36; 95% CI, 1.14-4.89). Bisexual men reported greater odds of asthma when measured by lifetime sexual behavior (aOR, 1.90; 95% CI, 1.12-3.19), as did self-identified heterosexual men with a history of same-sex sexual behavior (aOR, 2.21; 95% CI, 1.10-4.46). How we define sexual orientation influences our understanding of chronic disease prevalence. Capturing subgroups of sexual minority people in health surveillance is essential for identifying groups most at risk and developing targeted interventions to reduce chronic disease disparities.

Incidence of bronchitis and lung cancer in various parts of the city of Salford (generally polluted, crowded city) was related to air pollution as measured by 5 instruments scattered throughout. Average daily winter SO/sub 2/ ranged from 0.06 to 0.25 ppM and smoke from 0.45 to 0.77 mg/m/sup 3/. The different districts were crudely separated into 3 pollution categories. Mortality for the 3 areas from all causes was 106, 100, and 90% of that expected; from bronchitis, 128, 97, and 52%; from lung cancer, 124, 84, and 79%; from arteriosclerotic heart disease, 90, 98, and 120%; and from lesions of CNS, 75, 124, and 111%. These differences are significant for mortality, bronchitis, and lung cancer only. On 4 of 5 occasions when smoke reached 1 mg/m/sup 3/, bronchitis mortality was more than doubled (ratios 2.7:4.0). Observed bronchitis morbidity (incapacity) in working men 45 to 64 was 130, 90, and 60% of that expected for the high, medium, and low pollution areas, respectively.

VC, FVC, FEV1, FEV1/VC%, PEF, MEF25, MEF50, MEF75, TLC, TGV, RV, Raw, Rin, Rex, DLCO-SS, paO2 and paCO2 were determined in 22 patients with moderate chronic obstructive bronchitis (FEV1, 79-50% of the normal value). All the patients were found to have impaired bronchial patency, 90.9% of the patients had lung volume and capacity changes; pulmonary gas exchange dysfunction was present in 72.7%. Bronchial patency impairments were manifested by a decrease in FEV1, FEV1/VC%, PEF, MEF25, MEF50, MEF75, and an increase in Raw, Rin, Rex. Changes in the lung volumes and capacities appeared as higher RV, TGV, TLC, lower VC and FVC. Pulmonary gas exchange dysfunction showed up as a reduction in pO2 and DLCO-SS a reduction and an increase in paCO2. The magnitude of the functional changes observed in most patients was low. Significant and pronounced disorders were seen in one third of the patients.

Bronchitis mortality in males and females 45 to 65 or over 65 years of age was compared with air pollution in the county boroughs of England and Wales in 1950 to 1952. There was significant association between SO/sub 2/ and bronchitis mortality for men but only occasionally significant for women. Association between particulate matter and bronchitis was less consistent. Socio-economic class had no association with pollutant levels suggesting this factor does not affect bronchitis mortality significantly.

Relationship between the use of inhaled steroids for chronic respiratory diseases and early outcomes in community-acquired pneumonia.

Directory of Open Access Journals (Sweden)

Full Text Available BACKGROUND: The role of inhaled steroids in patients with chronic respiratory diseases is a matter of debate due to the potential effect on the development and prognosis of community-acquired pneumonia (CAP. We assessed whether treatment with inhaled steroids in patients with chronic bronchitis, COPD or asthma and CAP may affect early outcome of the acute pneumonic episode. METHODS: Over 1-year period, all population-based cases of CAP in patients with chronic bronchitis, COPD or asthma were registered. Use of inhaled steroids were registered and patients were followed up to 30 days after diagnosis to assess severity of CAP and clinical course (hospital admission, ICU admission and mortality. RESULTS: Of 473 patients who fulfilled the selection criteria, inhaled steroids were regularly used by 109 (23%. In the overall sample, inhaled steroids were associated with a higher risk of hospitalization (OR=1.96, p = 0.002 in the bivariate analysis, but this effect disappeared after adjusting by other severity-related factors (adjusted OR=1.08, p=0.787. This effect on hospitalization also disappeared when considering only patients with asthma (OR=1.38, p=0.542, with COPD alone (OR=4.68, p=0.194, but a protective effect was observed in CB patients (OR=0.15, p=0.027. Inhaled steroids showed no association with ICU admission, days to clinical recovery and mortality in the overall sample and in any disease subgroup. CONCLUSIONS: Treatment with inhaled steroids is not a prognostic factor in COPD and asthmatic patients with CAP, but could prevent hospitalization for CAP in patients with clinical criteria of chronic bronchitis.

Clinicoroentgenological control in chronic pneumonia

A comprehensive clinicoroentgenological study was used to examine 494 patients with chronic pneumonia. Morphological and functional changes observed in the pulmonary pare and functional changes observed in the pulmonary parenchyma and bronchial tree were studied. Types of pneumosclerosis, tigns of exacerbation of chronic pneumonia and abscess formation, morphological and functional disorders of bronchial penetrability in the pneumonic zone were described. Three forms of chronic pneumonia: bronchial, bronchiectatic and abscessing are signled out. The bronchial form is subdivided into chronic pneumonia with chronic bronchitis without deformity and wi.th deforming chronic bronchitis. In the bronchiectatic form pneumonia can be with cylindrical, saccular and cyst-like bronchiectasia. The general diagnosis of chronic pneumonia is established clinically depending on type and variants in 89-94% of cases, by X-ray and sonographic findings in all patients; types and variants of disease are most frequently defined after bronchography

Inadequate housing, low family income, household smoking, personal smoking status, and poor schooling are some of the conditions that have been significantly associated with the prevalence and incidence of chronic bronchitis. The aim of the current study was to determine the prevalence of chronic bronchitis (CB) and associated risk factors among First Nations people. An interviewer-administered survey was conducted as part of the First Nations Lung Health Project in 2012 and 2013 with 874 individuals from 406 households in two First Nations communities located in the province of Saskatchewan, Canada. The questionnaire collected information on individual and contextual determinants of health and a history of ever diagnosed with CB (outcome variable) from the two communities participating in the First Nations Lung Health Project. Clustering effect within households was adjusted using Generalized Estimating Equations. The prevalence of CB was 8.9% and 6.8% among residents (18 years and older) of community A and community B respectively and was not significantly different. CB prevalence was positively associated with odour or musty smell of mildew/mould in the house [OR adj (95% CI) = 2.33 (1.21, 4.50)], allergy to house dust [3.49 (1.75, 6.97)], an air conditioner in home [2.33 (1.18, 4.24)], and increasing age [0.99 (0.33, 2.95), 4.26 (1.74, 10.41), 6.08 (2.58, 14.33)]. An interaction exposure to environmental tobacco smoke in the house*body mass index showed that exposure to household smoke increased the risk of CB for overweight and obese participants (borderline). Some of the variables of interest were not significantly associated with the prevalence of CB in multivariable analysis, possibly due to small numbers. Our results suggest that significant determinants of CB were: increasing age; odour or musty smell of mildew/mould in the house; allergy to house dust; and, body mass index. Modifiable risk factors identified were: (i) community level

Rationale: Previous respiratory diseases have been associated with increased risk of lung cancer. Respiratory conditions often co-occur and few studies have investigated multiple conditions simultaneously. Objectives: Investigate lung cancer risk associated with chronic bronchitis, emphysema, tuberculosis, pneumonia, and asthma. Methods: The SYNERGY project pooled information on previous respiratory diseases from 12,739 case subjects and 14,945 control subjects from 7 case–control studies conducted in Europe and Canada. Multivariate logistic regression models were used to investigate the relationship between individual diseases adjusting for co-occurring conditions, and patterns of respiratory disease diagnoses and lung cancer. Analyses were stratified by sex, and adjusted for age, center, ever-employed in a high-risk occupation, education, smoking status, cigarette pack-years, and time since quitting smoking. Measurements and Main Results: Chronic bronchitis and emphysema were positively associated with lung cancer, after accounting for other respiratory diseases and smoking (e.g., in men: odds ratio [OR], 1.33; 95% confidence interval [CI], 1.20–1.48 and OR, 1.50; 95% CI, 1.21–1.87, respectively). A positive relationship was observed between lung cancer and pneumonia diagnosed 2 years or less before lung cancer (OR, 3.31; 95% CI, 2.33–4.70 for men), but not longer. Co-occurrence of chronic bronchitis and emphysema and/or pneumonia had a stronger positive association with lung cancer than chronic bronchitis “only.” Asthma had an inverse association with lung cancer, the association being stronger with an asthma diagnosis 5 years or more before lung cancer compared with shorter. Conclusions: Findings from this large international case–control consortium indicate that after accounting for co-occurring respiratory diseases, chronic bronchitis and emphysema continue to have a positive association with lung cancer.

Full Text Available Respiratory diseases, such as bronchitis and pneumonia, are common in First Nations children in Canada. The objectives are to determine prevalence and associated risk factors of bronchitis in children 6–17 years old residing in two reserve communities. The cross-sectional study was conducted in 2013 and children from two First Nations reserve communities participated. The outcome was ever presence/absence of bronchitis. Logistic regression analysis was conducted to examine the relationship between bronchitis and the individual and environmental factors. A total of 351 First Nations children participated in the study. The prevalence of bronchitis was 17.9%. While 86.6% had at least one parent who smoked, smoking inside home was 43.9%. Signs of mold and mildew in homes were high. Prevalence of houses with any damage caused by dampness was 42.2%, with 44.2% of homes showing signs of mold or mildew. Significant predictors of increased risk of bronchitis were: being obese; having respiratory allergies; exposed to parental cigarette smoking; and signs of mold and mildew in the home. There are several modifiable risk factors that should be considered when examining preventive interventions for bronchitis including obesity, smoking exposure, and home mold or dampness.

Full Text Available Abstract Background No study has been carried out on the time trend in the prevalence of chronic bronchitis (CB in recent years, despite its clinical and epidemiological relevance. We evaluated the trend in CB prevalence during the past decade among young Italian adults. Methods A screening questionnaire was mailed to general population samples of 20–44 year-old subjects in two cross-sectional surveys: the Italian Study on Asthma in Young Adults (ISAYA (1998/2000; n = 18,873, 9 centres and the screening stage of the Gene Environment Interactions in Respiratory Diseases (GEIRD study (2007/2010; n = 10,494, 7 centres. CB was defined as having cough and phlegm on most days for a minimum of 3 months a year and for at least 2 successive years. The prevalence rates and the risk ratios (RRs for the association between CB and each potential predictor were adjusted for gender, age, season of response, type of contact, cumulative response rate, and centre. Results CB prevalence was 12.5% (95% CI: 12.1-12.9% in 1998/2000 and 12.6% (95% CI: 11.7-13.7% in 2007/2010; it increased among never smokers (from 7.6 to 9.1%, p = 0.003, current light smokers ( Conclusions Despite the significant reduction in current smoking, CB prevalence did not vary among young Italian adults. The temporal pattern of CB prevalence can only be partly explained by the increase of unemployment/premature retirement, asthma and allergic rhinitis, and suggests that other factors could have played a role.

However, some of the patients presenting with symptoms of chronic airway diseases have clinical features of both asthma and COPD. The group with “Asthma–COPD Overlap Syndrome” (ACOS phenotype was characterized by definitely irreversible airway obstruction accompanied by symptoms and signs of reversibility. In this study, we aimed to classify obstructive airway diseases by clinical, radiological, and pulmonary function tests. Patients at Samsun Medical Park Hospital Chest Diseases outpatient clinic were evaluated between January 2013 and April 2016, and a total of 235 patients were included in this study. Mean age of the patients was 55.3±14.5 (15–88 years, and the male/female ratio was 45/190. The baseline pulmonary function test results of the patients were as follows: mean forced vital capacity (FVC values 2,825±1,108 (710–6,870 mL and 74.3±22.4 (24–155%, forced expiratory volume in 1 second (FEV1 values 1,789±774 (480–4,810 mL and 58.1±20.0 (20–130%, FEV1/FVC values 62.5±6.8 (39–70%.

INTRODUCTION: Acute bronchitis is a self-limiting infectious disease characterized by acute cough with or without sputum but without signs of pneumonia. About 90% of cases are caused by viruses. AREAS COVERED: Antibiotics for acute bronchitis have been associated with an approximately half......-day reduction in duration of cough. However, at follow-up there are no significant differences in overall clinical improvement inpatients treated with antibiotics compared with those receiving placebo. Despite this, antibiotics are administered to approximately two thirds of these patients. This review...... discusses the reason for this antibiotic overprescription. Other therapies targeted to control symptoms have also demonstrated a marginal or no effect. EXPERT COMMENTARY: Clinicians should be aware of the marginal effectiveness of antibiotic therapy. Some strategies like the use of rapid tests, delayed...

We tested the hypothesis that gastro-esophageal reflux disease is a risk factor for exacerbations in individuals with chronic obstructive pulmonary disease (COPD). Among 9622 participants in the Copenhagen City Heart Study, we identified 1259 individuals with COPD and information on gastro-esophageal reflux disease and the regular use of acid inhibitory treatment. These individuals were followed for 5 years with regard to medically treated COPD exacerbations, which we defined as a short course treatment with oral corticosteroids alone or in combination with antibiotics. We applied a multivariable Cox regression analysis with adjustment for well-established risk factors associated with COPD exacerbations or gastro-esophageal reflux disease, including COPD severity, and symptoms. Individuals with COPD and gastro-esophageal reflux disease had more chronic bronchitis (31 vs 21%, P = 0.004), more breathlessness (39 vs 22%, P gastro-esophageal reflux disease. Among individuals with COPD and gastro-esophageal reflux disease, those who did not use acid inhibitory treatment regularly had an increased risk of COPD exacerbations during follow-up, hazards ratio (HR): HR = 2.7 (1.3-5.4, P = 0.006). Individuals with gastro-esophageal reflux disease, using acid inhibitory treatment regularly did not have an increased risk of exacerbations, HR = 1.2 (0.6-2.7, P = 0.63). Gastro-esophageal reflux disease was associated with an increased risk of medically treated exacerbations of COPD, but only in those individuals who did not use acid inhibitory treatment regularly. © 2014 Asian Pacific Society of Respirology.

Data on chronic respiratory diseases (CRD) are scarce or unavailable in most African countries. We aimed to determine the prevalence of CRD and associated risk factors in Cape Verde, at the primary healthcare level. In the frame of the Global Alliance Against Chronic Respiratory Diseases, a cross-sectional study was carried out in October 2006 in 3256 outpatients (2142 women) (median age of 30 years) seeking care at primary healthcare departments, through a standardized interview questionnaire during two weeks. The prevalence of emphysema, tuberculosis, chronic bronchitis, rhinoconjunctivitis and asthma were 0.7%, 2%, 4.5%, 12.3% and 6.2%, respectively. Current smoking was associated with emphysema (OR: 3.36; 95% CI: 0.97-11.40) and tuberculosis (OR: 2.14; 95% CI: 1.07-4.30), ever exposed to a dusty workplace with chronic bronchitis (OR: 2.20; CI 95%: 1.50-3.21) and rhinoconjunctivitis (OR: 1.56; CI 95%: 1.23-1.98) and cooking or heating using an open fire with asthma (OR: 1.59; CI 95%: 1.16-2.19). The estimates of attributable risks percent indicated that, in the sample, a noticeable part of CRD could be attributed to active smoking, exposure to dust and biomass. Results varied according to gender, particularly regarding current smoking which was more important for men. Tobacco smoking, exposure to dust at work and using an open fire were important risk factors for CRD. Our results suggest that if actions were taken in order to reduce the aforementioned exposures, an important CRD decrease could be achieved. Copyright © 2015 Elsevier Masson SAS.

Patients with chronic obstructive pulmonary disease: management considerations for the dental team.

Science.gov (United States)

Devlin, J

2014-09-01

Chronic obstructive pulmonary disease (COPD) affects an estimated 3 million people in the United Kingdom, and is most common among elderly smokers. Patients may present with recurrent coughing of mucoid secretions (chronic bronchitis) or breathlessness caused by destruction of the airways (emphysema). If possible, it is advisable to treat the severely affected patients with them sitting upright in the dental chair as they may find it difficult to breathe when lying in the horizontal position. Periodontal bacteria can be carried into the lung where they can cause respiratory infection; therefore oral hygiene instruction should be emphasised in these patients. The objective of this article is to describe the oral and dental implications of chronic obstructive pulmonary disease. In particular, there have been a number of recent developments in the management of patients with COPD that have direct relevance to the dentist. The drug regime used in the treatment of patients with COPD can have profound implications for clinical dental practice, manifested as dry mouth or oral candidiasis. There is also increasing evidence of a link between COPD and both gastro-oesophageal reflux disease and periodontal disease.

1976-01-01

Because of the high frequency of chronic cor pulmonale in workers admitted to the cardiology department of the Khazaneh Hospital in Teheran, we studied the clinical aspect and the risk factors of this disease in 66 male patients. The average age of patients was 56.1 years and they often had a long history of bronchitis isolated or associated with emphysema. The ECG analysis showed that most abnormalities were localized on the QRST wave. Tobacco and a polluted working environment were the factors most frequently met in our patients. The opium habit probably acted as a risk factor for chronic bronchopneumopathy, but further studies are necessary to ascertain the fact.

Lung function is a strong predictor of overall mortality in asthma and chronic obstructive pulmonary disease (COPD). FEV1 is considered to be the "gold standard," whereas peak expiratory flow (PEF) is mostly used in absence of FEV1 measurements. We compared the predictive power of PEF and FEV1......, measured after maximal bronchodilation, which included a short course of oral corticosteroids. The study population comprised 491 asthmatics and 1,095 subjects with COPD.

COPD was defined as a postbronchodilator forced expiratory volume in 1 s/forced vital capacity ratio of 40 years who had undergone spirometry as a preoperative screening test, 474 (15.6%; 404 men; median age, 70 years; range, 44-93 years were diagnosed with COPD. Only 26 (5.5% patients reported previous diagnosis of COPD (2.1%, emphysema (0.8%, or chronic bronchitis (2.5%. The GOLD group distribution was as follows: 63.3% in group A, 31.2% in group B, 1.7% in group C, and 3.8% in group D.The prevalence of COPD diagnosed by preoperative spirometry was 15.6%, and only 5.5% patients were aware of their disease. Approximately one-third of the COPD patients belonged to GOLD groups B, C, and D, which require regular treatment.

Role of the inflammasome in chronic obstructive pulmonary disease (COPD).

2017-10-10

Inflammation is central to the development of chronic obstructive pulmonary disease (COPD), a pulmonary disorder characterized by chronic bronchitis, chronic airway obstruction, emphysema, associated to progressive and irreversible decline of lung function. Emerging genetic and pharmacological evidence suggests that IL-1-like cytokines are highly detected in the sputum and broncho-alveolar lavage (BAL) of COPD patients, implying the involvement of the multiprotein complex inflammasome. So far, scientific evidence has focused on nucleotide-binding oligomerization domain-like receptors protein 3 (NLRP3) inflammasome, a specialized inflammatory signaling platform that governs the maturation and secretion of IL-1-like cytokines through the regulation of caspase-1-dependent proteolytic processing. Some studies revealed that it is involved during airway inflammation typical of COPD. Based on the influence of cigarette smoke in various respiratory diseases, including COPD, in this view we report its effects in inflammatory and immune responses in COPD mouse models and in human subjects affected by COPD. In sharp contrast to what reported on experimental and clinical studies, randomized clinical trials show that indirect inflammasome inhibitors did not have any beneficial effect in moderate to severe COPD patients.

In the Genes Environment Interaction in Respiratory Diseases population-based multi-case control study, we investigated whether asthma, chronic bronchitis (CB) and rhinitis were associated with a reduced 6-minute walk distance (6MWD), and whether the 6MWD determinants were similar for subjects with/without respiratory diseases. Cases of asthma (n = 360), CB (n = 120), rhinitis (n = 203) and controls (no respiratory diseases: n = 302) were recruited. The variation in the 6MWD across the groups was analyzed by ANCOVA, adjusting for gender, age, height, weight and comorbidity. The 6MWD determinants were studied by linear regression, and heterogeneity across the cases and controls was investigated. The 6MWD differed across cases and controls (p = 0.01). It was shorter for cases of asthma (-17.1, 95% CI -28.3 to -5.8 m) and CB (-20.7, 95% CI: -36.6 to -4.8 m) than for controls (604 ± 68 m on average), but not for cases of rhinitis. The negative association between age and the 6MWD was significant for cases of CB, but not for the other groups (p = 0.001). Even at the level of severity found in the general population, asthma and CB could influence the 6MWD, which seems to reflect the functional exercise level for daily physical activities. The negative association between ageing and the 6MWD was particularly strong in subjects with CB. Our report adds to the mounting evidence that CB is not a trivial condition, especially in the ageing adult population, and it supports the importance of monitoring functional capacity and of physical reconditioning in mild asthma.

Persistent Bacterial Bronchitis: Time to Venture beyond the Umbrella

Directory of Open Access Journals (Sweden)

Andrew Bush

2017-12-01

Full Text Available Chronic cough in children is common and frequently mismanaged. In the past, cough was diagnosed as asthma and inappropriate asthma therapies prescribed and escalated. It has been realized that persistent bacterial bronchitis (PBB is a common cause of wet cough and responds to oral antibiotics. The initial definition comprised a history of chronic wet cough, positive bronchoalveolar (BAL cultures for a respiratory pathogen and response to a 2-week course of oral amoxicillin–clavulanic acid. This is now termed PBB-micro; PBB-clinical eliminates the need for BAL. PBB-extended is PBB-micro or PBB-clinical but resolution necessitating 4 weeks of antibiotics; and recurrent PBB is >3 attacks of PBB-micro or-clinical/year. However, the airway has only a limited range of responses to chronic inflammation and infection, and neutrophilic airway disease is seen in many other conditions, such as cystic fibrosis and primary ciliary dyskinesia, both chronic suppurative lung disease endotypes, whose recognition has led to huge scientific and clinical advances. There is an urgent need to extend endotyping into PBB, especially PBB-recurrent. We need to move from associative studies and, in particular, deploy sophisticated modern –omics technologies and systems biology, rather as has been done in the context of asthma in U-BIOPRED. In summary, the use of the term PBB has done signal service in pointing us away from prescribing asthma therapies to children with infected airways, but we now need to move beyond a simple description to teasing out underlying endotypes.

We examined the correlation between sputum colour and the presence of potentially pathogenic bacteria in acute exacerbations of chronic bronchitis (AECBs). Data were pooled from six multicentre studies comparing moxifloxacin with other antimicrobials in patients with an AECB. Sputum was collected before antimicrobial therapy, and bacteria were identified by culture and Gram staining. Association between sputum colour and bacteria was determined using logistic regression. Of 4,089 sputum samples, a colour was reported in 4,003; 1,898 (46.4%) were culture-positive. Green or yellow sputum samples were most likely to yield bacteria (58.9% and 45.5% of samples, respectively), compared with 18% of clear and 39% of rust-coloured samples positive for potentially pathogenic microorganisms. Factors predicting a positive culture were sputum colour (the strongest predictor), sputum purulence, increased dyspnoea, male sex and absence of fever. Green or yellow versus white sputum colour was associated with a sensitivity of 94.7% and a specificity of 15% for the presence of bacteria. Sputum colour, particularly green and yellow, was a stronger predictor of potentially pathogenic bacteria than sputum purulence and increased dyspnoea in AECB patients. However, it does not necessarily predict the need for antibiotic treatment in all patients with AECB.

[Rehabilitation of chronic obstructive pulmonary diseases at the lung hospital (author's transl)].

Meister, W

1979-12-01

The modern lung hospital offers favorable conditions for the rehabilitation of patients suffering from chronic obstructive pulmonary diseases. In the years from 1972 to 1976 2398 patients suffering from chronic bronchitis, bronchial asthma and pulmonary emphysema were subjected to a rehabilitation process at the central hospital for heart and lung diseases Bad Berka. A long-term therapy plan based on a most accurate investigation possible of all the factors which trigger off the complaint in each case was used as baseline. An account is given of the resulting diagnostic and therapeutic program carried out. In the case of chronic obstructive pulmonary diseases it is particularly difficult to assess the effectiveness of rehabilitation measures. One aspect dealt with is the restoration of working capacity. 56.7% of the men and 56.8% of the women were capable of working when they were dismissed. 31.6% of male and 26.4% of female patients were invalids, 11.7% and 16.8% respectively were old age pensioners. Rehabilitation success depended on variables such as age, degree of cardio-pulmonary limitation in performance, as well as on certain concomitant diseases and the patient's cooperation. A decisive factor in some cases was also whether suitable employment could be found for these patients whose age ranges between 40 and 60.

Plastic bronchitis is a rare cause of acute obstructive respiratory failure in children. Life-threatening events are much more frequent in patients with repaired cyanotic congenital heart disease, and most frequent following a Fontan operation. Commonly, the diagnosis is not made until bronchial casts are expectorated. Detailed CT findings in plastic bronchitis have not been described. To describe the CT findings in plastic bronchitis in children after a Fontan operation. Three children with plastic bronchitis after a Fontan operation were evaluated by chest CT. Bronchial casts were spontaneously expectorated and/or extracted by bronchoscopy. Airway and lung abnormalities seen on CT were analyzed in the three children. CT demonstrated bronchial casts in the central airways with associated atelectasis and consolidation in all children. The affected airways were completely or partially obstructed by the bronchial casts without associated bronchiectasis. The airway and lung abnormalities rapidly improved after removal of the bronchial casts. CT can identify airway and lung abnormalities in children with plastic bronchitis after a Fontan operation. In addition, CT can be used to guide bronchoscopy and to monitor treatment responses, and thereby may improve clinical outcomes. (orig.)

Full Text Available Objective: to study the specific features of the daily arterial stiffness (AS profile in men with different phenotypes of chronic obstructive pulmonary disease (COPD concurrent with hypertension. Subjects and methods. The investigation enrolled 78 male patients with COPD and hypertension. The patients were divided according to COPD phenotypes into 2 groups: 1 COPD patients with emphysema; 2 those with bronchitis. The exclusion criteria were less than 40 years and more than 80 years of age; diabetes mellitus; coronary heart disease; vascular diseases; an exacerbation of chronic diseases; bronchial and pulmonary diseases of another etiology. The patients underwent 24-hour blood pressure and AS monitoring, external respiratory function testing: spirography with a short-acting β2-agonist test, a six-minute walk test at baseline and after a hemoglobin oxygen saturation test, and a CAT test. Results. The patients of both groups were observed to have a statistically significant increase in (dP/dtmax as compared to those of the control group (p < 0.05; p < 0.01 in both the daytime and nighttime. In these periods, the COPD patients with emphysema had a higher AIx than those with bronchitis (p < 0.001. There was a statistically significantly (p < 0.001 higher AIx in the nighttime than in the daytime in Groups 1 and 2 patients. Conclusion. The patients with different COPD phenotypes were noted to have impaired arterial elastic properties, circadian AS changes with predominantly nocturnal impaired vascular stiffness. Relationships were found between 24-hour AS values and clinicoanamnestic findings. 

Chronic bronchitis and current smoking are associated with more goblet cells in moderate to severe COPD and smokers without airflow obstruction.

Full Text Available Goblet cell hyperplasia is a classic but variable pathologic finding in COPD. Current literature shows that smoking is a risk factor for chronic bronchitis but the relationship of these clinical features to the presence and magnitude of large airway goblet cell hyperplasia has not been well described. We hypothesized that current smokers and chronic bronchitics would have more goblet cells than nonsmokers or those without chronic bronchitis (CB, independent of airflow obstruction.We recruited 15 subjects with moderate to severe COPD, 12 healthy smokers, and 11 healthy nonsmokers. Six endobronchial mucosal biopsies per subject were obtained by bronchoscopy and stained with periodic acid Schiff-Alcian Blue. Goblet cell density (GCD was quantified as goblet cell number per millimeter of basement membrane. Mucin volume density (MVD was quantified as volume of mucin per unit area of basement membrane.Healthy smokers had a greater GCD and MVD than nonsmokers and COPD subjects. COPD subjects had a greater GCD than nonsmokers. When current smokers (healthy smokers and COPD current smokers, n = 19 were compared with all nonsmokers (nonsmoking controls and COPD ex-smokers, n = 19, current smokers had a greater GCD and MVD. When those with CB (n = 12 were compared to those without CB (n = 26, the CB group had greater GCD. This finding was also seen in those with CB in the COPD group alone. In multivariate analysis, current smoking and CB were significant predictors of GCD using demographics, lung function, and smoking pack years as covariates. All other covariates were not significant predictors of GCD or MVD.Current smoking is associated with a more goblet cell hyperplasia and number, and CB is associated with more goblet cells, independent of the presence of airflow obstruction. This provides clinical and pathologic correlation for smokers with and without COPD.

Saba Shirvan, Aylar; Mardani, Karim

2014-01-01

Infectious bronchitis (IB) and Newcastle disease (ND) are highly contagious and the most economically important diseases of the poultry affecting respiratory tract and causing economic losses in poultry industry throughout the world. In the present study, the simultaneous detection and differentiation of causative agents of these diseases were investigated using duplex-RT-PCR. RNA was extracted from vaccinal and reference strains of infectious bronchitis virus (IBV) and Newcastle disease virus (NDV) and then cDNA was synthesized. Using two universal primer sets for detection of IBV and NDV, the duplex-RT-PCR was developed. In order to assess the efficiency of the developed duplex RT-PCR, a number of 12 broiler farms with the symptoms of respiratory tract infection was sampled (trachea, lung and kidney were sampled from affected birds suspicious for IBV and NDV infections). After RNA extraction from tissues and cDNA synthesis, the presence of IBV and NDV genome were investigated using duplex-PCR. The results showed that three of twelve examined broiler farms were positive for IBV and two farms were positive for NDV and IBV. The results revealed that the duplex-RT-PCR is a quick and sensitive procedure for simultaneously detecting IBV and NDV in birds with respiratory infections.

Bronchitis: sickness absence in London Transport

Energy Technology Data Exchange (ETDEWEB)

Cornwall, C J; Raffle, P A.B.

1961-01-01

Analysis of records of bronchitis morbidity of 4 days or more among 60,000 male London Transport employees for the years 1952 to 1956 is discussed. Bronchitis morbidity accounted for about 10% of the absences, similar to that for the country as a whole. Annual inception rate increased with age after age 45; average length of spell increased with age over the whole age range. Absence from bronchitis broadly correlated with foggy periods (Dec, 52; Jan, 56), more so with city workers. Higher rates exist in north sectors where pollution is higher (south wind), and there is more industry and a higher population density. Lower rates exist among country workers. 20 to 25% of bronchitis morbidity can be ascribed to air pollution when country and city workers are compared.

Will chronic e-cigarette use cause lung disease?

Rowell, Temperance R; Tarran, Robert

Chronic tobacco smoking is a major cause of preventable morbidity and mortality worldwide. In the lung, tobacco smoking increases the risk of lung cancer, and also causes chronic obstructive pulmonary disease (COPD), which encompasses both emphysema and chronic bronchitis. E-cigarettes (E-Cigs), or electronic nicotine delivery systems, were developed over a decade ago and are designed to deliver nicotine without combusting tobacco. Although tobacco smoking has declined since the 1950s, E-Cig usage has increased, attracting both former tobacco smokers and never smokers. E-Cig liquids (e-liquids) contain nicotine in a glycerol/propylene glycol vehicle with flavorings, which are vaporized and inhaled. To date, neither E-Cig devices, nor e-liquids, are regulated by the Food and Drug Administration (FDA). The FDA has proposed a deeming rule, which aims to initiate legislation to regulate E-Cigs, but the timeline to take effect is uncertain. Proponents of E-Cigs say that they are safe and should not be regulated. Opposition is varied, with some opponents proposing that E-Cig usage will introduce a new generation to nicotine addiction, reversing the decline seen with tobacco smoking, or that E-Cigs generally may not be safe and will trigger diseases like tobacco. In this review, we shall discuss what is known about the effects of E-Cigs on the mammalian lung and isolated lung cells in vitro. We hope that collating this data will help illustrate gaps in the knowledge of this burgeoning field, directing researchers toward answering whether or not E-Cigs are capable of causing disease.

Khataby, Khadija; Fellahi, Siham; Loutfi, Chafiqa; Mustapha, Ennaji Moulay

2016-06-01

Infectious bronchitis virus (IBV) is worldwide in distribution, highly infectious, and extremely difficult to control because it has extensive genetic diversity, a short generation time, and a high mutation rate. IBV is a Gammacoronavirus, single-stranded, and positive-sense RNA virus. Avian infectious bronchitis is well studied in European countries with identification of a large number of IBV variants, whereas in African countries epidemiological and scientific data are poor and not updated. However, previous studies reported that an IBV variant continues to appear regularly in Africa, as currently described in Morocco. No cross-protection between IBV strains was reported, some being unique to a particular country, others having a more general distribution. This review aims to provide a general overview on IB disease distribution in African countries and an update on the available studies of IBV variants in each country.

There is increasing evidence that environmental factors such as air pollution from mine dumps, increase the risk of chronic respiratory symptoms and diseases. The aim of this study was to investigate the association between proximity to mine dumps and prevalence of chronic respiratory disease in people aged 55 years and older. Elderly persons in communities 1-2 km (exposed) and 5 km (unexposed), from five pre-selected mine dumps in Gauteng and North West Province, in South Africa were included in a cross-sectional study. Structured interviews were conducted with 2397 elderly people, using a previously validated ATS-DLD-78 questionnaire from the British Medical Research Council. Exposed elderly persons had a significantly higher prevalence of chronic respiratory symptoms and diseases than those who were unexposed., Results from the multiple logistic regression analysis indicated that living close to mine dumps was significantly associated with asthma (OR = 1.57; 95% CI: 1.20 - 2.05), chronic bronchitis (OR = 1.74; 95 CI: 1.25 - 2.39), chronic cough (OR = 2.02; 95% CI: 1.58 - 2.57), emphysema (OR = 1.75; 95% CI: 1.11 - 2.77), pneumonia (OR = 1.38; 95% CI: 1.07 - 1.77) and wheeze (OR = 2.01; 95% CI: 1.73 - 2.54). Residing in exposed communities, current smoking, ex-smoking, use of paraffin as main residential cooking/heating fuel and low level of education emerged as independent significant risk factors for chronic respiratory symptoms and diseases. This study suggests that there is a high level of chronic respiratory symptoms and diseases among elderly people in communities located near to mine dumps in South Africa.

[Bronchial inflammation during chronic bronchitis, importance of fenspiride].

Science.gov (United States)

Melloni, B

2002-09-01

PATHOPHYSIOLOGY OF CHRONIC OBSTRUCTIVE PULMONARY DISEASE (COPD): Chronic inflammation of the upper airways, pulmonary parenchyma and pulmonary vasculature is the characteristic feature of COPD. Two mechanisms besides inflammation are also involved: oxidative stress and imbalance between proteinases and antiproteinases. Cellular infiltration of the upper airways involved neutrophils, macrophages, T lymphocytes and eosinophils. Inflammatory mediators appear to play a crucial role in the interaction between inflammation and obstruction. PROPERTIES OF FENSPIRIDE: A nonsteroidal drug, fenspiride, exhibits interesting properties documented in vitro: anti-bronchoconstriction activity, anti-secretory activity, and anti-inflammatory activity (reduction in the activity of phospholipase A2 and release of proinflammatory leukotriens). Two french clinical trials have studied the efficacy of fenspiride in patients with acute excerbation or stable COPD and have demonstrated an improvement in the group treated with fenspiride compared with the placebo group.

Biomarkers of collagen turnover are related to annual change in FEV1 in patients with chronic obstructive pulmonary disease within the ECLIPSE study

Construction workers employed in a unique type of tunnel construction known as tunnel jacking were exposed over an 18-month period to respirable crystalline silica at concentrations that exceeded the OSHA permissible exposure limit. The present study examines workplace exposures and occurrence of airway disease in these workers. Medical and occupational histories and chest radiographs were obtained on 343 active construction workers who had worked on the site during the period in question. Chest radiographs were interpreted according to the ILO-1980 system of classification. Standardized questions were used to develop an algorithm to define symptoms consistent with asthma (SCA) and to determine these respiratory outcomes: chronic bronchitis, shortness of breath (SOB), and physician-diagnosed asthma (current vs. not current). Relationships with each of three work activities were examined: slurry wall breakthrough (SWB), chipping caisson overpour, and tunneling/mining. Participants included laborers, carpenters, tunnel workers, ironworkers, operating engineers, and electricians. No cases of silicosis were found on chest X-ray. Overall prevalence of chronic bronchitis, SCA, SOB, and physician-diagnosed asthma was 10.7%, 25%, 29%, and 6.6%, respectively. Odds ratios (OR) for carpenters compared to laborers were significantly elevated for chronic bronchitis, SCA, and SOB. SWB was associated with chronic bronchitis and SCA (OR 4.93, 95% CI = 1.01, 24.17; OR 3.32, 95% CI = 1.25, 8.84, respectively). The interaction between SWB, SCA, and trade was significant for carpenters (OR 6.87, 95% CI = 1.66, 28.39). Inverse trends were observed for months on the site and chronic bronchitis, SCA, and SOB (P = 0.0374, 0.0006, and 0.0307, respectively). Tunnel construction workers exposed to respirable crystalline silica and cement dust are at increased risk for airway disease. Extent of risk varies by trade and work activity. Our data indicate the importance of bystander exposures and

Standardized mortality ratios for lung cancer and bronchitis decreased with population gradient from urban to rural areas. When this was controlled, SO/sub 2/ and smoke concentration were highly correlated with each other and with bronchitis but not with lung cancer. Conversely, lung cancer was correlated with population density whereas bronchitis was not. This study postulates that bronchitis offers some form of immunological protection against lung cancer.

Large differences in prevalence of asthma have been reported between westernised countries and the former Eastern European countries, and still no consensus about the reasons for the differences exists. The aim of this study was to assess diagnostic labelling of obstructive airway diseases, comparing subjects with respiratory symptoms and the diagnoses obtained in Estonia, Finland, and Sweden. A postal questionnaire was sent to population-based random samples, and 44,483 (76%) answers were obtained from the 58,661 invited in 1996. Among men, current smoking was most common in Estonia, 60%, followed by Finland, 39%, and Sweden, 28%. In all three countries, 30% of women were current smokers. Most respiratory symptoms including wheezing were most common in Estonia, also among non-smokers. The prevalence of asthma was 2.0% and chronic bronchitis 10.7% in Estonia, while the opposite was found in Sweden with an asthma prevalence of 7.8% and a chronic bronchitis prevalence of 3.1%. The pattern in Finland was similar to that of Sweden. The same differences between the three countries were found also among young subjects. The total proportion of diagnosed obstructive lung diseases in subjects with respiratory symptoms was similar, but the diagnosis of asthma was considerably more common in Finland and Sweden. Chronic bronchitis was favoured in Estonia, also among young adults irrespectively of what symptoms were present. In a multivariate model with correction for confounders, the risk (OR) for having a diagnosis of asthma was 5.65 (95% CI: 4.86-6.56) when living in Sweden, and 3.51 (95% CI: 3.00-4.12) in Finland, whereas risk for chronic bronchitis was 0.28 (0.25-0.31) and 0.22 (0.19-0.25), respectively, compared to Estonia. The study indicates differences in diagnostic practices of obstructive lung diseases between the three countries

19 elements (Ca, Mg, Fe, Se, Cu, Zn, etc.) in hair of 65 patients with chronic bronchitis, pulmonary emphysema and corpulmonale and 65 healthy persons were determined with instrumental neutron activation analysis. It was shown that the contents of Ca and Mg are lower while the contents of Fe, As and Co higher for the patients. For the patients with chronic bronchitis in attack period the contents of Ca and Mg are lower and the content of Fe higher than those in relaxed period. A highly positive relation between Ca and Mg contents was also found. In addition, inorganic elements in 'Kechuandeping' capsule, a prepared traditional Chinese medicine to treat chronic bronchitis, were determined, and the contents of Ca, Mg, Sr, etc. were found higher than the corresponding average values for 120 kinds of traditional Chinese medicines, indicating a possible shortage of Ca, Mg, etc. for the patients with respiratory-system diseased

Aspergillus in chronic lung disease: Modeling what goes on in the airways.

Aspergillus species cause a range of respiratory diseases in humans. While immunocompromised patients are at risk for the development of invasive infection with these opportunistic molds, patients with underlying pulmonary disease can develop chronic airway infection with Aspergillus species. These conditions span a range of inflammatory and allergic diseases including Aspergillus bronchitis, allergic bronchopulmonary aspergillosis, and severe asthma with fungal sensitization. Animal models are invaluable tools for the study of the molecular mechanism underlying the colonization of airways by Aspergillus and the host response to these non-invasive infections. In this review we summarize the state-of-the-art with respect to the available animal models of noninvasive and allergic Aspergillus airway disease; the key findings of host-pathogen interaction studies using these models; and the limitations and future directions that should guide the development and use of models for the study of these important pulmonary conditions. © The Author 2016.

Effect of decimeter range waves in combination with drug electroaerosols on immunoinflammatory processes during chronic nonspecific lung diseases

Energy Technology Data Exchange (ETDEWEB)

Ayrapetova, N.S.; Tkachenko, A.F.

An attempt was made to optimize the therapy of chronic nonspecific pulmonary diseases using a combination of decimeter range waves (DRW) and broncholytic electroaerosols. The electroaerosols penetrate rapidly deep into the lungs up to the aveoli, combining the action of an electric charge with the pharmaceutical effect. In all, 232 patients were studied (94.8% with chronic bronchitis, 5.2% with chronic pneumonia) manifesting an active inflammatory process, disturbance of the immune status and diminished glucocorticoid activity. After 15 procedures of combined therapy, 88.5% of the patients showed improvement in their clinical status; 65.4% of the control group (receiving only the electroaerosol) also showed improvement. In this combined therapy, the antiinflammatory and immunosuppressive effect were achieved due to the action of DRW; the electroaerosols had a positive effect on the function state of the cardiorespiratory system. 11 references.

Radiocardiography and rheography of the pulmonary artery were used to examine impairments in hemodynamics and contractile function of the right ventricle in 40 patients with chronic obstructive bronchitis complicated with persistent hypertension. Right ventricular hemodynamic and contractile impairments were shown to be not equivalent with similar clinical and functional signs of pulmonary hypertension. This fact indicates that the use of special techiques is of practical value in the determination of right ventricular hemodynamics and myocardial contractility in patients with chronic obstructive bronchitis. Radiocardiography and rheography of the pulmonary artery are sufficiently reliable noninvasive techniques for examining the hemodynamics and contractile function of the right ventricular myocardium

However, there has been a rapid increase in the prevalence, morbidity, and mortality of COPD in women over the last two decades. This has largely been attributed to historical increases in tobacco consumption among women. But the influence of sex on COPD is complex and involves several other factors, including differential susceptibility to the effects of tobacco, anatomic, hormonal, and behavioral differences, and differential response to therapy. Interestingly, nonsmokers with COPD are more likely to be women. In addition, women with COPD are more likely to have a chronic bronchitis phenotype, suffer from less cardiovascular comorbidity, have more concomitant depression and osteoporosis, and have a better outcome with acute exacerbations. Women historically have had lower mortality with COPD, but this is changing as well. There are also differences in how men and women respond to different therapies. Despite the changing face of COPD, care providers continue to harbor a sex bias, leading to underdiagnosis and delayed diagnosis of COPD in women. In this review, we present the current knowledge on the influence of sex on COPD risk factors, epidemiology, diagnosis, comorbidities, treatment, and outcomes, and how this knowledge may be applied to improve clinical practices and advance research.

Adults with chronic lower respiratory disease differ in their barriers to smoking cessation but also suffer from tobacco-related health concerns, which may motivate quit attempts. Few studies have examined differences in tobacco treatment response between smokers with and without chronic lower respiratory disease. We examined the effectiveness of a proactive outreach program for cessation among smokers with and without chronic lower respiratory disease. Subgroup analysis of the Veterans Victory over Tobacco Study, a pragmatic randomized controlled trial that demonstrated the effectiveness of proactive outreach and the choice of tobacco treatments compared with usual care. Smokers identified via the electronic medical record were proactively offered phone-based counseling and care coordination to receive medication from their Veterans Affairs providers or in-person care. We compared the response among those with and without an International Classification of Diseases, 9th Revision diagnosis of a chronic lower respiratory disease (chronic obstructive pulmonary disease, chronic bronchitis, emphysema, asthma). We used stratification by propensity scores to adjust for imbalanced covariates between groups with and without chronic lower respiratory disease within each treatment arm, using complete case analysis accounting for the stratified sampling by site. The study participants were predominantly older, white, male smokers. Overall, 19.6% had chronic lower respiratory disease. A total of 3,307 had outcome data with the following assignments to the intervention: proactive care: n = 1,272 without chronic lower respiratory disease, n = 301 with chronic lower respiratory disease; usual care: n = 1,387 without chronic lower respiratory disease, n = 347 with chronic lower respiratory disease. A total of 1,888 had both complete baseline and outcome data and were included in the primary analysis. In unadjusted analyses (n = 3,307), among individuals with

Particulate matter with a diameter below 10 µ (PM10) has been a major concern in the Tamar Valley, Launceston, where wood heaters are extensively used. We examined the relationship between PM10 levels, meteorological variables, respiratory medications and hospital admissions for respiratory disease over the decade 1992-2002. PM10 levels were provided by the Department of Primary Industry Water, Parks and Environment, and meteorological variables from the Bureau of Meteorology. We obtained hospital discharge codes for the Launceston General Hospital. Poisson regression was used for statistical analyses. Mean daily PM10 levels declined from 50.7 to 16.5 μg/m(3). Hospitalisations for asthma decreased from 29 to 21 per month, whereas chronic obstructive pulmonary disease (COPD) increased and bronchitis/bronchiolitis remained unchanged. We found a 10 μg/m(3) increase in PM10 to be associated with a 4% increase in admissions for acute bronchitis/bronchiolitis (p0.05), but no association with asthma or COPD was found. All respiratory diseases showed seasonal patterns of hospitalisation. This is the first long-term study in Australia to demonstrate an association between PM10 levels and respiratory diseases. Reducing exposure to PM10 may decrease hospital admissions for respiratory diseases. Better preventive measures, including sustained public health initiatives to combat air pollution, are required to reduce respiratory morbidity.

Minimum concentrations of NO/sub 2/ causing acute effects on the respiratory gas exchange and airway-resistance in patients with chronic bronchitis

Nitrogen dioxide-air mixtures containing 0.5 to 5.0 ppM NO/sub 2/ were inhaled by 88 patients with chronic bronchitis over a 15-minute period for a total of 30 breaths during studies investigating the effects of the gas on airway resistance and respiratory gas exchange. End-expiratory oxygen pressures remained nearly constant during inhalation of 4 or 5 ppM NO/sub 2/, though significant decreases in arterial oxygen pressure accompanied by increases in end-expiratory-arterial oxygen pressure difference occurred. Inhalation of 2 ppM NO/sub 2/ did not decrease arterial oxygen pressure. Airway resistances increased significantly down to 1.5 ppM NO/sub 2/ concentrations. Lower concentrations caused no significant effects.

The main purpose of the paper was to compare the effects of outdoor and indoor air quality on the development of chronic respiratory diseases measured in the prospective study of chronic chest diseases among the inhabitants of Cracow, Poland. The 5-year follow-up study covered a probability sample of 4355 adult inhabitants. Data on respiratory symptoms and lung function in addition to variables related to environmental and socioeconomic factors were included. To assess the separate and joint effects of the chosen environmental factors on chronic chest problems, the multiple logistic regression analysis has been carried out. As expected, smoking habit was the strongest single of the factors related to the persistence of the respiratory symptoms. The effect of smoking was more marked in men than in women and this can be attributed to longer duration of smoking and more cigarettes smoked daily by men. Out of all considered adverse occupational factors only chemicals increased the risk of chronic bronchitis in men while dust increased the risk of exacerbations in women. The data showed a significant decrease in risk of exacerbations among the women who used a gas stove for cooking. The study also confirmed the harmful effect of smoking on lung function. Against this particular background the importance of variable temperature combined with ambient air pollution appeared to have rather strong detrimental biologic impact.

Air pollution in Japan caused respiratory disease, such as chronic bronchitis and asthma, in many individuals in the 1960s. Although air pollution has decreased, many victims of air pollution-related respiratory disease are limited in their activities of daily living because of respiratory symptoms. The purpose of this study was to evaluate the efficacy of pulmonary rehabilitation in victims of air pollution-related chronic bronchitis or asthma. Subjects were enrolled in a 12-week (2-week inpatient followed by 10-week outpatient) pulmonary rehabilitation program. The program comprised conditioning, strength training, endurance training, and patient education. We assessed the Modified Medical Research Council (MMRC) dyspnea grade, pulmonary function, peripheral muscle force, incremental shuttle walk distance (ISWD), and physical activity at baseline and immediately after the program. Twenty-nine subjects (mean age 74.2 ± 10.1 years, 11 males) completed the program, including 11 subjects with COPD and 18 subjects with asthma. Following rehabilitation, the participants (n = 29) showed significant improvements in MMRC dyspnea grade, vital capacity % predicted, quadriceps force and ISWD (all P pollution-related asthma. In conclusion, we recommend that patients with chronic bronchitis or asthma, resulting from exposure to air pollution, are referred for pulmonary rehabilitation.

1989-01-01

A study was made of the action of inhalation of a single atrovent dose in 20 patients with chronic obstructive bronchitis. All the patients demonstrated a considerable abatement or disappearance of dyspnea, and a reduction of the number of dry rales. The vital capacity of the lungs, the volume of forced expiration, maximal pulmonary ventilation, MOCmax, MOC50, and MOC75 substantially increased. The respiratory work diminished on the average by 32.3% primarily due to the lessening of non-elastic lung resistance. The rise of pulmonary static extensibility and reduction of pulmonary elastic propulsion were recorded. In patients with and without clinical signs of bronchospasm, the action of atrovent was identical.

To quantify the impact of non-adherence on the clinical effectiveness of antibiotics for acute exacerbations of chronic bronchitis (AECB) and to estimate the economic consequences for Spain, Italy and the United States. Standard systematic reviewing procedures were followed to identify randomised controlled clinical trials of antibiotic treatment for acute respiratory tract infection for which adherence was reported. A decision-analytic model was then constructed to evaluate the impact of non-adherence to antibiotic treatment on clinical effectiveness and costs per AECB episode. The model compared the total treatment costs, cure rates and incremental costs per cure for a poor compliance group (PCG) against a good compliance group (GCG). Clinical and resource use estimates were from the published literature and physician surveys. Twenty-five articles met the criteria of the systematic review, although only one reported treatment success by adherence status. The relative risk of clinical effectiveness if non-adherent was 0.75 (95%CI 0.73-0.78). Based on this single study, the model predicted that 16-29% more patients would be cured in the GCG vs. the PCG, and payers would save up to euro122, euro179 and US$141 per AECB episode in Spain, Italy and the United States, respectively. Non-adherence to antibiotics for AECB may have an impact on clinical effectiveness, which is associated with increased costs.

2004-01-01

Chronic obstructive pulmonary disease and congestive heart failure are two increasingly prevalent chronic diseases. Although care for these patients often is provided by different clinical teams, both disease conditions have much in common. In recent decades, more knowledge about the systemic impact of both diseases has become available, highlighting remarkable similarities in terms of prognostic factors and disease management. Rehabilitation programs deal with the systemic consequences of both diseases. Although clinical research also is conducted by various researchers investigating chronic obstructive pulmonary disease and chronic heart failure, it is worthwhile to compare the progress in relation to these two diseases over recent decades. Such comparison, the purpose of the current review, may help clinicians and scientists to learn about progress made in different, yet related, fields. The current review focuses on the similarities observed in the clinical impact of muscle weakness, the mechanisms of muscle dysfunction, the strategies to improve muscle function, and the effects of exercise training on chronic obstructive pulmonary disease and chronic heart failure.

1986-05-01

An experimental group and a control group identical in age, work experience, dust exposure and expression of disease were treated for dust-induced bronchitis. The control group received broncholytics, anti-inflammatory preparations and physiotherapy; the experimental group received same treatment plus 200 ml of rheopolyglucin, a 10% solution of dextran (water-soluble polysaccharide of glucose), twice a week for 2 to 3 weeks. In addition to general laboratory and clinical methods of investigation, cytologic analysis of sputum before and after treatment was carried out. Results of experiment are given in 3 tables showing: Dynamics of Allergic Signs after Treatment with Rheopolyglucin, Dynamics of Content of Eosinophils in Blood after Treatment, and Cytologic Characteristics of Mucus of Patients with Dust-Induced Bronchitis. Patients treated with rheopolyglucin improved more than control group in abatement of suppurative process in lungs, strengthening of specific cellular and humoral mechanisms of immune response at level of bronchopulmonary system, increased expulsion of mineral dust from lungs and significant reduction of allergic reaction. Results quantitated in tables prove advantages of adding rheopolyglucin to traditional therapy in treatment of dust-induced bronchitis. 19 refs.

19 elements, such as Ca, Mg, Fe, Se, Cu, Zn, etc., in hair of 65 patients with chronic bronchitis, pulmonary emphysema and cor-pulmonale diseases and 65 healthy people have been investigated by instrumental neutron activation analysis. The results show that the contents of Ca and Mg are lower and Fe, As and Co are higher in the hair of patients than in healthy persons. The contents of Ca and Mg are lower and Fe is higher in the hair of patients during attack periods of chronic bronchitis than in relaxed periods. The differences are significant (P<0.05-0.01). The content of Ca is closely related to that of Mg in hair (P<0.01). The contents of inorganic elements in the Chinese medicine cough and asthma capsule used to treat chronic bronchitis have been determined. The results show that the contents of elements Ca, Mg, Sr, etc., are higher in this medicine than the average amounts of these elements in 120 other Chinese medicines. (author) 15 refs.; 8 tabs

Household air pollution (HAP) due to biomass cooking fuel use is an important risk factor for a range of diseases, especially among adult women who are primary cooks, in India. About 80% of rural households in India use biomass fuel for cooking. The aim of this study is to estimate the attributable cases (AC) for four major diseases/conditions associated with biomass cooking fuel use among adult Indian women. We used the population attributable fraction (PAF) method to calculate the AC of chronic bronchitis, tuberculosis (TB), cataract, and stillbirths due to exposure to biomass cooking fuel. A number of data sources were accessed to obtain population totals and disease prevalence rates. A meta-analysis was conducted to obtain adjusted pooled odds ratios (ORs) for strength of association. Using this, PAF and AC were calculated using a standard formula. Results were presented as number of AC and 95% confidence intervals (CI). The fixed effects pooled OR obtained from the meta-analysis were 2.37 (95% CI: 1.59, 3.54) for chronic bronchitis, 2.33 (1.65, 3.28) for TB, 2.16 (1.42, 3.26) for cataract, and 1.26 (1.12, 1.43) for stillbirths. PAF varied across conditions being maximum (53%) for chronic bronchitis in rural areas and least (1%) for cataract in older age and urban areas. About 2.4 (95% CI: 1.4, 3.1) of 5.6 m cases of chronic bronchitis, 0.3 (0.2, 0.4) of 0.76 m cases of TB, 5.0 (2.8, 6.7) of 51.4 m cases of cataract among adult Indian women and 0.02 (0.01, 0.03) of 0.15 m stillbirths across India are attributable to HAP due to biomass cooking fuel. These estimates should be cautiously interpreted in the light of limitations discussed which relate to exposure assessment, exposure characterization, and age-specific prevalence of disease. HAP due to biomass fuel has diverse and major impacts on women's health in India. Although challenging, incorporating the agenda of universal clean fuel access or cleaner technology within the broader framework of rural

The benefits and risks of antibiotics for acute bronchitis remain unclear despite it being one of the most common illnesses seen in primary care. To assess the effects of antibiotics in improving outcomes and to assess adverse effects of antibiotic therapy for people with a clinical diagnosis of acute bronchitis. We searched CENTRAL 2016, Issue 11 (accessed 13 January 2017), MEDLINE (1966 to January week 1, 2017), Embase (1974 to 13 January 2017), and LILACS (1982 to 13 January 2017). We searched the World Health Organization International Clinical Trials Registry Platform (WHO ICTRP) and ClinicalTrials.gov on 5 April 2017. Randomised controlled trials comparing any antibiotic therapy with placebo or no treatment in acute bronchitis or acute productive cough, in people without underlying pulmonary disease. At least two review authors extracted data and assessed trial quality. We did not identify any new trials for inclusion in this 2017 update. We included 17 trials with 5099 participants in the primary analysis. The quality of trials was generally good. At follow-up there was no difference in participants described as being clinically improved between the antibiotic and placebo groups (11 studies with 3841 participants, risk ratio (RR) 1.07, 95% confidence interval (CI) 0.99 to 1.15). Participants given antibiotics were less likely to have a cough (4 studies with 275 participants, RR 0.64, 95% CI 0.49 to 0.85; number needed to treat for an additional beneficial outcome (NNTB) 6) and a night cough (4 studies with 538 participants, RR 0.67, 95% CI 0.54 to 0.83; NNTB 7). Participants given antibiotics had a shorter mean cough duration (7 studies with 2776 participants, mean difference (MD) -0.46 days, 95% CI -0.87 to -0.04). The differences in presence of a productive cough at follow-up and MD of productive cough did not reach statistical significance.Antibiotic-treated participants were more likely to be improved according to clinician's global assessment (6 studies

A high proportion of the world population, especially in developing countries, is exposed to indoor pollutants produced by inefficient biomass stoves. The levels of pollutants, including toxins and carcinogens in the kitchen are usually very high. This potential pathogenic exposure has been scarcely studied. The exposure to biomass smoke has been associated to chronic bronchitis and chronic airflow obstruction in adults and to acute respiratory infections in children. At the National Institute of Pulmonary Diseases in Mexico, we have observed the entire spectrum of diseases associated with tobacco in people who never smoked and who were exposed to wood smoke. Women exposed to wood smoke had a five-fold risk of chronic bronchitis and chronic airflow obstruction, as compared to the non-exposed, according to a recent case-control study done at our Institute. The indoor levels of suspended particles smaller than 10 microns were frequently above 1,000 micrograms/m3 in a rural community in the state of Mexico. This information supports a causal role for biomass smoke for the genesis of several respiratory diseases, representing a potentially public health problem.

Full Text Available Time to first cigarette (TTFC after waking is an indicator of nicotine dependence. The association between TTFC and chronic obstructive pulmonary disease (COPD, the third leading cause of death in the United States, has not yet been reported.We investigated the cross-sectional association between TTFC and prevalent COPD among 6,108 current smokers in the Prostate, Lung, Colorectal, and Ovarian (PLCO Cancer Screening Trial. COPD was defined as a self-reported diagnosis of emphysema, chronic bronchitis, or both. Current smokers in PLCO reported TTFC, the amount of time they typically waited before smoking their first cigarette of the day after waking, in four categories: ≤ 5, 6-30, 31-60, or > 60 minutes. We used logistic regression models to investigate the association between TTFC and prevalent COPD with adjustments for age, gender, race, education, and smoking (cigarettes/day, years smoked during lifetime, pack-years, age at smoking initiation, and prior lung cancer diagnosis.COPD was reported by 19% of these 6,108 smokers. Individuals with the shortest TTFC had the greatest risk of COPD; compared to those with the longest TTFC (> 60 minutes the adjusted odds ratios (OR and 95% confidence intervals (CI for COPD were 1.48 (95% CI, 1.15-1.91, 1.64 (95% CI, 1.29-2.08, 2.18 (95% CI, 1.65-2.87 for those with TTFC 31-60 minutes, 6-30 minutes, and ≤ 5 minutes, respectively (P-trend 60 minutes, the adjusted OR (95% CI was 2.29 (1.69-3.12 for emphysema and 2.99 (1.95-4.59 for chronic bronchitis.Current smokers with shorter TTFC have increased risk of COPD compared to those with longer TTFC, even after comprehensive adjustment for established smoking covariates. Future epidemiologic studies, including prospective designs, should incorporate TTFC to better assess disease risk and evaluate the potential utility of TTFC as a COPD screening tool for smokers in the clinical setting.

Bronchopulmonary hygiene physical therapy in bronchiectasis and chronic obstructive pulmonary disease: a systematic review.

This study had two objectives: (1) to examine the effects of bronchopulmonary hygiene physical therapy on patients with chronic obstructive pulmonary disease and bronchiectasis; (2) to determine any differences between manual and mechanical techniques for bronchopulmonary hygiene physical therapy. The study design was a systematic review of the literature that used an exhaustive search for trials and review methods prescribed by the Cochrane Collaboration. Randomized controlled trials examined patient groups, interventions, and dependent variables. Patients included those with chronic obstructive pulmonary diseases (emphysema or chronic bronchitis) or bronchiectasis. Any of the following interventions or combinations thereof were included: manual interventions, such as postural drainage, chest percussion, vibration, chest shaking, directed coughing, or forced exhalation technique. Controls of the study were as follows: no intervention; placebo; coughing; and mechanical interventions, such as mechanical vibration. The search identified 99 potential trials; inclusion or exclusion analysis left 7, which examined a total of 126 patients. Mean score on trial quality was 1.4 (5 = greatest). Three separate trials (N = 51) found statistically significant effects for bronchopulmonary hygiene physical therapy on sputum production and radioaerosol clearance. No trials (N = 126) found statistically significant effects on pulmonary function variables or differences between manual and mechanical techniques. Considering the small sizes, low quality, and mixed results from the trials, the research on bronchopulmonary hygiene physical therapy is inconclusive. There is a need for adequately sized, high-quality, randomized controlled trials with uniform patient populations to examine the effects of bronchopulmonary hygiene physical therapy.

The effects of fluticasone propionate (FP) on sputum chemotactic activity, elastase inhibitory potential, albumin concentrations, and peripheral neutrophil function were studied in a group of patients with clinically stable, smoking-related chronic bronchitis and emphysema. Seventeen patients (50 to 75 yr of age) were entered into a double-blind, placebo-controlled study of 1.5 mg inhaled FP/d for 8 wk. Following treatment with FP the chemotactic activity of the sputum sol phase was lower than the corresponding values for the placebo group (p < 0.01). Values fell from a mean of 21.75 (+/- 1.58) during the run-in period to 18.37 (+/- 1.46; p < 0.01) after 4 wk and 17.63 (+/- 1.86; p < 0.05) after 8 wk treatment returning to 22.08 (+/- 1.26) cell/field after the washout period. The neutrophil elastase inhibitory capacity of the sputum sol phase increased (p < 0.025) with treatment from a mean of 0.177 microM elastase inhibited/L (+/- 0.05) pretreatment to 0.413 microM (+/- 0.054) after 4 wk and 0.415 microM (+/- 0.054) after 8 wk returning to 0.270 microM (+/- 0.07) after the washout period. Treatment with FP did not result in a change in the peripheral neutrophil functions studied or sputum albumin and myeloperoxidase concentrations. The results suggest that FP may play a protective role in these patients through a reduction in the chemotactic activity of lung secretions and potentially a reduction in the recruitment of neutrophils to the lung, and also by directly affecting the proteinase/antiproteinase balance, in favor of antiproteinases, within lung secretions.

Full Text Available This study evaluates the effects of Sargassum pallidum polysaccharides (SPP on the immune responses in a chicken model. The adjuvanticity of Sargassum pallidum polysaccharides in Newcastle disease (ND, infectious bronchitis (IB and avian influenza (AI was investigated by examining the antibody titers and lymphocyte proliferation following immunization in chickens. The chickens were administrated combined ND, IB and AI inactivated vaccines containing SPP at 10, 30 and 50 mg/mL, using an oil adjuvant vaccine as a control. The ND, IB and AI antibody titers and the lymphocyte proliferation were enhanced at 30 mg/mL SPP. In conclusion, an appropriate dose of SPP may be a safe and efficacious immune stimulator candidate that is suitable for vaccines to produce early and persistent prophylaxis.

To investigate associations between respiratory disease and occupational exposures in a New Zealand urban population, the Wellington Respiratory Survey. Multiple regression analyses in a population sample of 1017 individuals aged 25 to 74 years with spirometry and questionnaire information, including a lifetime occupational history. Chronic bronchitis symptoms were associated with self-reported exposure to hairdressing, paint manufacturing, insecticides, welding, detergents and with ALOHA Job Exposure Matrix-assessed gases/fumes exposure. The strongest association was for hairdressing (odds ratio 6.91; 95% confidence interval: 2.02 to 23.70). Cumulative exposure to mineral dust and gases/fumes was associated with higher FEV₁% (forced expiratory volume in the first second of expiration) predicted. Analyses were limited by relatively small numbers of cases. Increased risks of objectively defined respiratory disease, which have been previously documented, were not seen. Nevertheless, the study suggested increased risk of respiratory symptoms with various occupational exposures as well as likely healthy worker effect.

Background: Few studies have assessed the impact of residential home characteristics and home environmental risk factors on respiratory diseases in Chinese women. Therefore, this study sought to determine the association between residential home features, domestic pets, home renovation and other indoor environmental risk factors with respiratory health outcomes of Chinese women. Methods: This cross-sectional study included a study sample of 30,780 Chinese women aged 23 to 49 from 25 districts of seven cities in Liaoning Province, Northeast China. Information on respiratory health, residential characteristics, and indoor air pollution sources was obtained by a standard questionnaire from the American Thoracic Society. Multivariable logistic regression was used to estimate prevalence odds ratios (POR) and 95% confidence interval (95%CI). Results: The odds of respiratory diseases were higher for those who lived near the main road, or near ambient air pollution sources. Pet-keeping was associated with increased odds of chronic bronchitis (POR = 1.40; 95%CI: 1.09–1.81) and doctor-diagnosed asthma (POR = 2.07; 95%CI: 1.18–3.64). Additionally, humidifier use was associated with increased odds of chronic bronchitis (POR = 1.44; 95%CI: 1.07–1.94). Home renovation in recent 2 years was associated with increased likelihood of allergic rhinitis (POR = 1.39; 95%CI 1.17–1.64). Conclusion: Home renovation and residential home environmental risk factors were associated with an increased likelihood of respiratory morbidity among Chinese women. - Highlights: • Relatively few significant associations were observed. • Pet ownership was associated with increased odds of asthma and chronic bronchitis. • Home renovation was associated with increased odds of allergic rhinitis in women. • Humidifier use was associated with increased odds of chronic bronchitis in women.

The avian infectious bronchitis virus main protease has been crystallized; crystals diffract to 2.7 Å resolution. Infectious bronchitis virus (IBV) is the prototype of the genus Coronavirus. It causes a highly contagious disease which affects the respiratory, reproductive, neurological and renal systems of chickens, resulting great economic losses in the poultry industry worldwide. The coronavirus (CoV) main protease (M{sup pro}), which plays a pivotal role in viral gene expression and replication through a highly complex cascade involving the proteolytic processing of replicase polyproteins, is an attractive target for antiviral drug design. In this study, IBV M{sup pro} was overexpressed in Escherichia coli. Crystals suitable for X-ray crystallography have been obtained using microseeding techniques and belong to space group P6{sub 1}22. X-ray diffraction data were collected in-house to 2.7 Å resolution from a single crystal. The unit-cell parameters were a = b = 119.1, c = 270.7 Å, α = β = 90, γ = 120°. Three molecules were predicted to be present in the asymmetric unit from a calculated self-rotation function.

Full Text Available Infectious bronchitis (IB disease is a viral contagious respiratory disease. The causing agent of this disease has several serotypes. In this study, 4/91 type of Infectious bronchitis (IB was identified. For this, tracheal samples were taken from 18 broiler chickens flocks having respiratory signs suspected to IB disease with one percent mortality in day. After RNA extraction from tissue samples in one step RT-PCR reaction, a fragment of S1 gene was amplified by common primers for all IB viruses. Then RT-PCR product was amplified for identification of 4/91(793/B type by type specific primers in Nested-PCR. Results showed, 11 out 18 flocks (61.1% were infected to IB that 45.45% of IB infected flocks were infected to 4/91 type. Therefore it seems 4/91 type of IB has role in forming and complexing of respiratory signs in broiler chickens suffering to respiratory syndrome in Chahrmahal-va-bakhtiyari province and it is necessary to give a suitable controlling strategy for prevention of 4/91 infection.

A study was conducted of civil servants, principally postmen, to standardize social class and pay in morbidity and mortality correlations with air pollution. This group was also compared with the general population. Frequency of winter fog was related to severe chronic bronchitis in both groups studied. Bronchitis absence rate among postmen working outdoors in areas of high presumptive air pollution was higher than that of indoor male workers. Colds and sore throats show the same selective incidence. There was a steady rise in bronchitis rate with age among postmen whereas that of indoor male workers increased only after age 45. Lung cancer apparently was not related to air pollution. The urban factor in infectious diseases could be the increased chance of contact. Uncontrolled factors in this type of study include: difference in morale, individual-job type selection, job criteria, and sick leave and retirement policy.

Chronic periodontitis, inflammatory cytokines, and interrelationship with other chronic diseases.

Periodontal diseases, such as chronic periodontitis, share common inflammatory risk factors with other systemic and chronic inflammatory disorders. Mucosal tissues, such as oral epithelia, are exposed to environmental stressors, such as tobacco and oral bacteria, that might be involved in promoting a systemic inflammatory state. Conversely, chronic disorders can also affect oral health. This review will summarize recent evidence for the interrelationship between chronic periodontitis and other prevalent chronic diseases such as cardiovascular diseases, diabetes, cancer and chronic respiratory diseases. The association with pregnancy is also included due to possible obstetric complications. We will focus on inflammatory cytokines such as TNF-alpha, IL-1, and IL-6, because they have been shown to be increased in patients with chronic periodontitis, in patients with chronic systemic diseases, and in patients with both chronic periodontitis and other chronic diseases. Therefore, an imbalance towards a proinflammatory immune response could underline a bidirectional link between chronic periodontitis and other chronic diseases. Finally, we highlight that a close coordination between dental and other health professionals could promote oral health and prevent or ameliorate other chronic diseases.

Results. We have examined 80 children aged from 6 months to 3 years with acute obstructive bronchitis, and 40 age-matched children with acute nonobstructive bronchitis. The factors of high risk were determined and the mathematical model for predicting bronchial obstruction in acute bronchitis was created. Father’s age over 38 years, intrauterine growth restriction, maladjustment syndrome, early artificial feeding, genetic predisposition to atopy, passive smoking, fever in the postvaccination period, history of acute obstructive bronchitis and number of its episodes more than 2, paratrophia became prognostically significant. Fever up to 37.7 °C, mild intoxication syndrome up to 3 days, slow nasal breathing, IL-13 within 4.05–6.71 pg/ml and the relative number of lymphocytes expressing NF-kB less than 49.8 % were also associated with the development of bronchial obstruction in acute bronchitis.

As a coordinated research project of the International Atomic Energy Agency (IAEA), a multicentre joint study on radioaerosol lung scan using the BARC nebulizer has prospectively been carried out during 1988-1992 with the participation of 10 member countries in Asia [Bangladesh, China, India, Indonesia, Japan, Korea, Pakistan, Philippines, Singapore and Thailand]. The study was designed so that it would primarily cover chronic obstructive pulmonary disease (COPD) and the other related and common pulmonary diseases. The study also included normal controls and asymptomatic smokers. The purposes of this presentation are three fold: firstly, to document the usefulness of the nebulizer and the validity of user's protocol in imaging COPD and other lung diseases; secondly, to discuss scan features of the individual COPD and other disorders studied and thirdly, to correlate scan alterations with radiographic findings. Before proceeding with a systematic analysis of aerosol scan patterns in the disease groups, we documented normal pattern. The next step was the assessment of scan features in those who had been smoking for more than several years but had no symptoms or signs referable to airways. The lung diseases we analyzed included COPD [emphysema, chronic bronchitis, asthma and bronchiectasis], bronchial obstruction, compensatory overinflation and other common lung diseases such as lobar pneumonia, tuberculosis, interstitial fibrosis, diffuse panbronchiolitis, lung edema and primary and metastatic lung cancers. Lung embolism, inhalation bums and glue-sniffer's lung are separately discussed by Dr. Sundram of Singapore elsewhere in this book. The larger portion of this chapter is allocated to the discussion of COPD with a special effort made in sorting out differential scan features. Diagnostic criteria in individual COPD were defined for each category of disease and basic clinical symptoms and signs and pertinent laboratory data as well as radiographic manifestations are

Full Text Available Quality of life is an important indicator in assessing the burden of disease, especially for chronic conditions. The Health Utilities Index (HUI is a recently developed system for measuring the overall health status and health-related quality of life (HRQL of individuals, clinical groups, and general populations. Using the HUI (constructed based on eight attributes: vision, hearing, speech, mobility, dexterity, cognition, emotion, and pain/discomfort to measure the HRQL for chronic disease patients and to detect possible associations between HUI system and various chronic conditions, this study provides information to improve the management of chronic diseases.This study is of interest to data analysts, policy makers, and public health practitioners involved in descriptive clinical studies, clinical trials, program evaluation, population health planning, and assessments. Based on the Canadian Community Health Survey (CCHS for 2000–01, the HUI was used to measure the quality of life for individuals living with various chronic conditions (Alzheimer/other dementia, effects of stroke, urinary incontinence, arthritis/rheumatism, bowel disorder, cataracts, back problems, stomach/intestinal ulcers, emphysema/COPD, chronic bronchitis, epilepsy, heart disease, diabetes, migraine headaches, glaucoma, asthma, fibromyalgia, cancers, high blood pressure, multiple sclerosis, thyroid condition, and other remaining chronic diseases. Logistic Regression Model was employed to estimate the associations between the overall HUI scores and various chronic conditions. The HUI scores ranged from 0.00 (corresponding to a state close to death to 1.00 (corresponding to perfect health; negative scores reflect health states considered worse than death. The mean HUI score by sex and age group indicated the typical quality of life for persons with various chronic conditions. Logistic Regression results showed a strong relationship between low HUI scores (≤ 0.5 and 0.06�

Infectious bronchitis, a disease of chickens caused by Avian coronavirus infectious bronchitis virus (IBV), leads to severe economic losses for the poultry industry worldwide. Various attempts to control the virus based on vaccination strategies are performed. However, due to the emergence of novel genotypes, an effective control of the virus is hindered. In 1996, a novel viral genotype named IBV-QX was reported for the first time in Qingdao, Shandong province, China. The first appearance of an IBV-QX isolate in Europe was reported between 2003 and 2004 in The Netherlands. Subsequently, infections with this genotype were found in several other European countries such as France, Italy, Germany, United Kingdom, Slovenia, and Sweden. The present report describes the use of a new set of degenerate primers that amplify a 636-bp fragment within the S1 gene by reverse transcription polymerase chain reaction to detect the occurrence of IBV-QX infection in Switzerland.

Significance of zonography and bronchozonography in diagnosis of chronic nonspecific diseases if the lungs

1979-01-01

By comparing data obtained in complex x-ray examination (roentgenography, tomography, bronchotomography, zonography and bronchozonography) of 175 patients with chronic bronchitis, chronic pneumonia and chronic lung abscesses it was established that zonography and bronchozonography make it possible to obtain much more diagnostic information than tomo- and bronchotomography. Bronchial and vascular elements can be seen on zonograms 1.5-2 times more often than on tomograms. The use of zonography and bronchozonography is advisable for detection of weakly pronounced peribronchial of pleurocortical pneumosclerosis, small and medium-size inflammatory foci, small cavities of abscesses as well as for the study of changes in the lung outline and round formations with 3-4 cm in diameter. Zonography has no advantages over tomography in the studies of pulmonary abscesses accompanied by marked infiltrative changes, pneumosclerosis and reactive pleural complications

Branched-chain aminoacids and retraining of patients with chronic obstructive lung disease.

Menier, R; Talmud, J; Laplaud, D; Bernard, M P

2001-12-01

The aim of this work was to improve the efficacy of rehabilitation by retraining, by oral supply in branched-chain aminoacids (BCAA). Patients with chronic respiratory insufficiency mainly suffer from obstructive bronchitis due to tobacco or asthma. Nutritional assessment is one of the components of respiratory rehabilitation, with retraining. Intense physical training for several days negativates the nitrogen balance, the beginning of a training programme for sedentary patients increases their need in proteins. An additional supply in branched-chain aminoacids increases proteic anabolism, by synthesis increase and catabolism slackening of proteins. Moreover it is known that exposure to high altitude reduces lean mass by inducing a muscular atrophy, which can be avoided by the BCAA provided. This leads to wonder if extra supply of BCAA could play similar role in muscular mass loss induced by pathological chronic hypoxia. The prospective and comparative survey carried out in Toki-Eder (private hospital in Cambo) consisted in supplying (during five weeks or more) 30 retrained patients suffering from chronic obstructive bronchitis, and in matching them with 30 witnesses (obstructive patients retrained without additional supply in BCAA). Their mean hypoxemia amounted to 7 torr for age. Each of them improved their reached maximal power, and their VO2 SL, very highly significantly. Each of them developed a moderate metabolic acidosis (whose possible mechanisms are discussed) and slightly increased their ventilation at rest. On the other hand only the supplied patients improved their PaO2 at rest highly significantly, a result which poses the question of the responsible mechanism, most likely a decrease of pulmonary shunt effect. The hypotheses concerning the acid load due to BCAA ingestion are discussed. Only the supplied patients developed hypocapnia expressing a gaseous alkalosis which might be due to a direct effect of BCAA on the respiratory centers. This observation

Infectious bronchitis (IB) and Newcastle disease (ND) are common viral diseases of chickens, which are caused by infectious bronchitis virus (IBV) and Newcastle disease virus (NDV), respectively. Vaccination with live attenuated strains of IBV-H120 and NDV-LaSota are important for the control of IB and ND. However, conventional live attenuated vaccines are expensive and result in the inability to differentiate between infected and vaccinated chickens. Therefore, there is an urgent need to develop new efficacious vaccines. In this study, using a previously established reverse genetics system, we generated a recombinant IBV virus based on the IBV H120 vaccine strain expressing the haemagglutinin-neuraminidase (HN) protein of NDV. The recombinant virus, R-H120-HN/5a, exhibited growth dynamics, pathogenicity and viral titers that were similar to those of the parental IBV H120, but it had acquired hemagglutination activity from NDV. Vaccination of SPF chickens with the R-H120-HN/5a virus induced a humoral response at a level comparable to that of the LaSota/H120 commercial bivalent vaccine and provided significant protection against challenge with virulent IBV and NDV. In summary, the results of this study indicate that the IBV H120 strain could serve as an effective tool for designing vaccines against IB and other infectious diseases, and the generation of IBV R-H120-HN/5a provides a solid foundation for the development of an effective bivalent vaccine against IBV and NDV.

1995-12-01

A population-based case-control study was performed in Stockholm to assess the influence of air pollution on the occurrence of severe wheezing bronchitis in children. The study included 197 children aged 4 months to 4 years, who were hospitalized because of breathing difficulties with wheezing, and 350 population controls. Information on potential risk factors for childhood wheezing and a residential history was obtained at home interview with parents. Outdoor nitrogen dioxide (NO2) concentrations at home addresses and day care centres from birth on were estimated from validated models, mainly using data on traffic intensity from municipal registers. The risk of wheezing bronchitis was related to time-weighted mean outdoor NO2 exposure in girls (P = 0.02), but not in boys. A gas stove in the home appeared to be a risk factor primarily for girls. All analyses controlled for parental asthma and maternal smoking, which were independent risk factors for wheezing bronchitis. The results suggest that exposure to combustion products containing NO2 may be of particular importance for the development of wheezing bronchitis in girls.

Its management can be difficult. We present here an overview of the current guidelines for the management of chronic cough. Different steps are detailed, including the initial research of an obvious etiology and alert signs that should lead to further investigation of underlying condition. The diagnosis of the most frequent causes: asthma, non-asthmatic eosinophilic bronchitis, gastroesophageal reflux disease and upper airway cough syndrome should be considered, assessed and treated accordingly. Recent advances have been made in the comprehension of refractory chronic cough pathophysiology as well as its pharmacologic and non-pharmacologic treatment, especially speech pathology therapy.

The commercial flocks in Yucatan, Mexico are free of Newcastle disease virus (NDV) in its velogenic viscerotropic form, but little is known about the disease status of backyard poultry. A seroprevalence survey in 30 villages using haemagglutination inhibition (HI) tests for infectious bronchitis virus (IBV) and NDV antibodies was carried out from December 1997 to June 1998. The seroprevalences were 56.5% (95% CI 50-63%) for IBV and 2.2% (95% CI 0.5-3.8%) for NDV. All the villages had chickens that were positive for antibodies to IBV and nine of the villages had chickens that were positive for antibodies to NDV. This suggests that IBV may be responsible for a large proportion of the respiratory disease observed in backyard chickens in Yucatan. The implications of these findings are discussed, including the highly susceptible status of the backyard chickens in Yucatan to NDV and the possibility of this virus being one cause of the syndrome known as mortandad by the local people.

A screening complex for the examination of the rural population has been worked out to detect bronchopulmonary pathology and form groups of risk for respiratory diseases. The complex of methods included compulsory questionnaires and ++fluoro-functional examination, spirometry if indicated and bacterial tests. Out of 1, 131 persons examined, 328 were found to have respiratory diseases. Chronic non-specific respiratory diseases were detected in 103 subjects, including 62 of them having obstructive bronchitis. A risk group developing chronic non-specific respiratory diseases, including 202 persons with disturbed ventilation activity of the lungs, post-tuberculous inadequate changes and other pathology. Pulmonary tuberculosis was registered in 7 subjects. The given data indicate the necessity of a complex examination of the population.

New Directions in Chronic Disease Management

Directory of Open Access Journals (Sweden)

Hun-Sung Kim

2015-06-01

Full Text Available A worldwide epidemic of chronic disease, and complications thereof, is underway, with no sign of abatement. Healthcare costs have increased tremendously, principally because of the need to treat chronic complications of non-communicable diseases including cardiovascular disease, blindness, end-stage renal disease, and amputation of extremities. Current healthcare systems fail to provide an appropriate quality of care to prevent the development of chronic complications without additional healthcare costs. A new paradigm for prevention and treatment of chronic disease and the complications thereof is urgently required. Several clinical studies have clearly shown that frequent communication between physicians and patients, based on electronic data transmission from medical devices, greatly assists in the management of chronic disease. However, for various reasons, these advantages have not translated effectively into real clinical practice. In the present review, we describe current relevant studies, and trends in the use of information technology for chronic disease management. We also discuss limitations and future directions.

There are a variety of dermatological diseases that are more commonly seen in patients with chronic kidney disease (CKD) and renal transplants than the general population. Directory of Open Access Journals (DOAJ), Google Scholar, Pubmed (NLM), LISTA (EBSCO) and Web of Science has been searched. Some cutaneous diseases are clearly unique to this population. Of them, Lindsay's Nails, xerosis cutis, dryness of the skin, nephrogenic systemic fibrosis and acquired perforating dermatosis have been described in chronic kidney disease patients. The most common malignancy found in all transplant recipients is non-melanoma skin cancer. It is important for patients and physicians to recognize the manifestations of skin disease in patients suffering from chronic kidney disease to mitigate the morbidity associated with these conditions.

Should patients with acute exacerbation of chronic bronchitis be treated with antibiotics? Advantages of the use of fluoroquinolones.

Science.gov (United States)

Mensa, J; Trilla, A

2006-05-01

The pathological changes in chronic bronchitis (CB) produce airflow obstruction, reduce the effectiveness of the mucocilliary drainage system and lead to bacterial colonisation of bronchial secretion. The presence of bacteria induces an inflammatory response mediated by leukocytes. There is a direct relationship between the degree of impairment of the mucocilliary drainage system, the density of bacteria in mucus and the number of leukocytes in the sputum. Purulent sputum is a good marker of a high bacterial load. Eventually, if the number of leukocytes is high, their normal activity could decrease the effectiveness of the drainage system, increase the bronchial obstruction and probably damage the lung parenchyma. Whenever the density of bacteria in the bronchial lumen is >or=10(6) CFU/mL, there is a high probability that the degree of inflammatory response will lead to a vicious cycle which in turn tends to sustain the process. This situation can arise during the clinical course of any acute exacerbation of CB, independently of its aetiology, provided the episode is sufficiently severe and/or prolonged. Fluoroquinolones of the third and fourth generation are bactericidal against most microorganisms usually related to acute exacerbations of CB. Their diffusion to bronchial mucus is adequate. When used in short (5-day) treatment they reduce the bacterial load in a higher proportion than is achieved by beta-lactam or macrolide antibiotics given orally. Although the clinical cure rate is similar to that obtained with other antibiotics, the time between exacerbations could be increased.

The value of the abnormalities of bronchovascular bundles in the diagnosis of diffused lung diseases

International Nuclear Information System (INIS)

Li Tieyi; Ji Jingling

1997-01-01

To evaluate the abnormalities of bronchovascular bundles in the differential diagnosis of the diffuse lung disease, seventy-two patients with diffuse lung diseases were evaluated, 15 of 72 patients were pathologically proven and the others clinically proven. Of these 72 patients, there were 33 patients with diffuse pulmonary interstitial disease, 5 patients with pulmonary parenchymal disease, 14 patients with bronchial disease, and 20 patients with disseminated disease. All patients had conventional CT scan of the chest, some also had HRCT scan. All CT images were jointly reviewed by two radiologists. The features of the abnormalities of bronchovascular bundles included: (1) Thinning of bronchovascular bundles, predominantly seen in diffuse interstitial disease of lung and chronic bronchitis; (2) thickening of bronchovascular bundles, predominantly seen in interstitial diseases and disseminated lung diseases such as sarcoidosis and lymphangitis carcinomatosis with beaded appearance of bronchovascular bundles; (3) Increased visibility of bronchovascular bundles, predominantly seen in bronchiolitis and disseminated lung diseases. CT features of the abnormalities of bronchovascular bundles are present in 80% of diffuse lung diseases. The features are not specific, but the beaded bronchovascular bundles are always seen in sarcoidosis and lymphangitis carcinomatosis. In making a distinction between idiopathic pulmonary fibrosis and chronic bronchitis complicated with interstitial fibrosis, the position of diaphragm is of value in differential diagnosis, normal or elevated diaphragm is usually seen in the former, while low and flattened diaphragm in the latter. Change of the appearance of bronchovascular bundles from normality to abnormality reflects the process of development of the lung disease

Voetsch, Karen; Sequeira, Sonia; Chavez, Amy Holmes

2016-03-31

In 2012, the Centers for Disease Control and Prevention provided funding and technical assistance to all states and territories to implement the Coordinated Chronic Disease Program, marking the first time that all state health departments had federal resources to coordinate chronic disease prevention and control programs. This article describes lessons learned from this initiative and identifies key elements of a coordinated approach. We analyzed 80 programmatic documents from 21 states and conducted semistructured interviews with 7 chronic disease directors. Six overarching themes emerged: 1) focused agenda, 2) identification of functions, 3) comprehensive planning, 4) collaborative leadership and expertise, 5) managed resources, and 6) relationship building. These elements supported 4 essential activities: 1) evidence-based interventions, 2) strategic use of staff, 3) consistent communication, and 4) strong program infrastructure. On the basis of these elements and activities, we propose a conceptual model that frames overarching concepts, skills, and strategies needed to coordinate state chronic disease prevention and control programs.

HIV/AIDS, chronic diseases and globalisation.

2011-08-26

HIV/AIDS has always been one of the most thoroughly global of diseases. In the era of widely available anti-retroviral therapy (ART), it is also commonly recognised as a chronic disease that can be successfully managed on a long-term basis. This article examines the chronic character of the HIV/AIDS pandemic and highlights some of the changes we might expect to see at the global level as HIV is increasingly normalised as "just another chronic disease". The article also addresses the use of this language of chronicity to interpret the HIV/AIDS pandemic and calls into question some of the consequences of an uncritical acceptance of concepts of chronicity.

Fisetin and Its Role in Chronic Diseases.

Pal, Harish C; Pearlman, Ross L; Afaq, Farrukh

2016-01-01

Chronic inflammation is a prolonged and dysregulated immune response leading to a wide variety of physiological and pathological conditions such as neurological abnormalities, cardiovascular diseases, diabetes, obesity, pulmonary diseases, immunological diseases, cancers, and other life-threatening conditions. Therefore, inhibition of persistent inflammation will reduce the risk of inflammation-associated chronic diseases. Inflammation-related chronic diseases require chronic treatment without side effects. Use of traditional medicines and restricted diet has been utilized by mankind for ages to prevent or treat several chronic diseases. Bioactive dietary agents or "Nutraceuticals" present in several fruits, vegetables, legumes, cereals, fibers, and certain spices have shown potential to inhibit or reverse the inflammatory responses and several chronic diseases related to chronic inflammation. Due to safe, nontoxic, and preventive benefits, the use of nutraceuticals as dietary supplements or functional foods has increased in the Western world. Fisetin (3,3',4',7-tetrahydroxyflavone) is a dietary flavonoid found in various fruits (strawberries, apples, mangoes, persimmons, kiwis, and grapes), vegetables (tomatoes, onions, and cucumbers), nuts, and wine that has shown strong anti-inflammatory, anti-oxidant, anti-tumorigenic, anti-invasive, anti-angiogenic, anti-diabetic, neuroprotective, and cardioprotective effects in cell culture and in animal models relevant to human diseases. In this chapter, we discuss the beneficial pharmacological effects of fisetin against different pathological conditions with special emphasis on diseases related to chronic inflammatory conditions.

Lung diseases in the elderly. Pathogenetic significance of pollutants and environmental factors

In the elderly pneumoconioses due to anorganic or organic dusts are not very common. The incidence of mesothelioma is increasing also in the elderly population. Mesothelioma has become the most frequent occupational malignancy. There is also evidence that mesothelioma can be produced by other fibers than asbestos particles. The paper discusses further the effect of passive smoking, where there is new evidence that passive-smokers are exposed to a higher risk for bronchial cancer than non-smokers. The interactions between smoking and air pollution and morbidity of chronic bronchitis are illustrated. New aspects of pathogenesis and pathophysiology of chronic obstructive lung disease and pulmonary emphysema due to smoking as the most frequent environmental lung disease in the elderly are further discussed. A brief overview of the therapeutical approach to chronic obstructive lung disease including new forms of treatment of cor pulmonale is finally given.

Infectious bronchitis (IB) is a highly contagious respiratory and urogenital disease of chickens caused by infectious bronchitis virus (IBV). This disease is of considerable economic importance and is primarily controlled through biosecurity and immunization with live attenuated and inactivated IB vaccines of various serotypes. In the present study, we tested the safety and efficacy of an attenuated predominant Chinese QX-like IBV strain. The results revealed that the attenuated strain has a clear decrease in pathogenicity for specific-pathogen-free (SPF) chickens compared with the parent strain. Strain YN-inoculated birds had clinical signs of varying severity with 30% mortality, while the attenuated group appeared healthy, with less tissue damage. The attenuated strain also had relatively low tissue replication rates and higher antibody levels. The superior protective efficacy of the attenuated strain was observed when vaccinated birds were challenged with a homologous or heterologous field IBV strain, indicating the potential of the attenuated YN (aYN) as a vaccine. Producing a vaccine targeting the abundant serotype in China is essential to reducing the economic impact of IB on the poultry industry. Copyright © 2015 Elsevier B.V. All rights reserved.

Chronic respiratory infectious diseases are causing high rates of morbidity and mortality worldwide. Tuberculosis, a major cause of chronic pulmonary infection, is currently responsible for approximately 1.5 million deaths per year. Although important advances in the fight against tuberculosis have been made, the progress towards eradication of this disease is being challenged by the dramatic increase in multidrug-resistant bacilli. Nontuberculous mycobacteria causing pulmonary disease and chronic pulmonary aspergillosis are emerging infectious diseases. In contrast to other infectious diseases, chronic respiratory infections share the trait of having highly variable treatment outcomes despite longstanding antimicrobial therapy. Recent scientific progress indicates that medicine is presently at a transition stage from programmatic to personalized management. We explain current state-of-the-art management concepts of chronic pulmonary infectious diseases as well as the underlying methods for therapeutic decisions and their implications for personalized medicine. Furthermore, we describe promising biomarkers and techniques with the potential to serve future individual treatment concepts in this field of difficult-to-treat patients. These include candidate markers to improve individual risk assessment for disease development, the design of tailor-made drug therapy regimens, and individualized biomarker-guided therapy duration to achieve relapse-free cure. In addition, the use of therapeutic drug monitoring to reach optimal drug dosing with the smallest rate of adverse events as well as candidate agents for future host-directed therapies are described. Taken together, personalized medicine will provide opportunities to substantially improve the management and treatment outcome of difficult-to-treat patients with chronic respiratory infections. © 2016 S.

Etiology and immunology of infectious bronchitis virus

Directory of Open Access Journals (Sweden)

LF Caron

2010-06-01

Full Text Available Infectious bronchitis virus (IBV of chickens is currently one of the main diseases associated with respiratory syndrome in domestic poultry, as well as with losses related to egg production. The etiological agent is a coronavirus, which presents structural differences in the field, mainly in the S1 spike protein. The immune response against this virus is complicated by the few similarities among serotypes. Environmental and management factors, as well as the high mutation rate of the virus, render it difficult to control the disease and compromise the efficacy of the available vaccines. Bird immune system capacity to respond to challenges depend on the integrity of the mucosae, as an innate compartment, and on the generation of humoral and cell-mediated adaptive responses, and may affect the health status of breeding stocks in the medium run. Vaccination of day-old chicks in the hatchery on aims at eliciting immune responses, particularly cell-mediated responses that are essential when birds are first challenged. Humoral response (IgY and IgA are also important for virus clearance in subsequent challenges. The presence of antibodies against the S1 spike protein in 3- to 4-week-old birds is important both in broilers and for immunological memory in layers and breeders.

This European Respiratory Society statement provides a comprehensive overview on protracted bacterial bronchitis (PBB) in children. A task force of experts, consisting of clinicians from Europe and Australia who manage children with PBB determined the overall scope of this statement through consensus. Systematic reviews addressing key questions were undertaken, diagrams in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement constructed and findings of relevant studies summarised. The final content of this statement was agreed upon by all members.The current knowledge regarding PBB is presented, including the definition, microbiology data, known pathobiology, bronchoalveolar lavage findings and treatment strategies to manage these children. Evidence for the definition of PBB was sought specifically and presented. In addition, the task force identified several major clinical areas in PBB requiring further research, including collecting more prospective data to better identify the disease burden within the community, determining its natural history, a better understanding of the underlying disease mechanisms and how to optimise its treatment, with a particular requirement for randomised controlled trials to be conducted in primary care.

The Prevention of Chronic Kidney Disease (CKD) is placed in the more general context of prevention of major chronic Non Communicable Diseases (NCDs): cardiovascular diseases, diabetes, chronic lung diseases and tumors that are the main problem for public health worldwide. Any health policy strategy aimed to the prevention of NCDs has to provide knowledge of health and socioeconomic status of the population, to reduce the level of exposure to risk factors and to adapt health services to the request for assistance. To this purpose, population monitoring systems have been implemented in the last years. The NCDs share some risk factors that are related, in large part, to unhealthy individual behaviours: smoking, alcohol abuse, unhealthy diet and physical inactivity. NCDs prevention has to be understood as the set of all actions, sanitary and not, aiming to prevent or delay the onset of diseases or their complications. Preventive measures should, therefore, involve not only the health sector but also all the actors that can help to prevent that disease. As for the Prevention of CKD, the Ministry of Health has established a working table, which handled the Drafting of the "Position paper for the CKD", approved in the State-Regions Conference on august 8th 2014. The document draws a national strategy to combat this disease through primary prevention, early diagnosis and the establishment of diagnostic - therapeutic pathways (DTP).

Chronic kidney disease (CKD) represents a serious public health problem due to the increase in incidence and prevalence of this disease worldwide. Given the significant morbidity and mortality from cardiovascular disease (CVD) in the population of patients with CKD, and the fact that dyslipidemia itself is a risk factor for CVD, increases the importance of lipid metabolism study in patients with CKD. Evaluate the lipid status of patients with chronic kidney disease. A one-year prospective study included 150 adult patients who were in various stages of chronic renal failure (stage I to IV). Estimate of creatinine clearance was performed using Cockroft-Goult formula. The classification of patients according to stages of chronic renal insufficiency was performed in accordance with the criteria of Kidney Disease Outcomes Quality Initiative (K/DOQI). Of the total number of patients (N=150) there was 71 males and 79 females. The mean age of patients was 55.43 years. Average values of serum cholesterol were highest in patients with stage II renal disease and the lowest in patients classified as stage IV (5.76±1.60 mmol/L vs. 5.07±1.88 mmol/L). Analysis of the average value of triglycerides in blood show a slight increase through the stages of CKD in a manner that patients classified into stage I have low serum triglyceride levels (1.73±1.17 mmol/L (range 0.61 to 5.5 mmol/L), and patients classified in stage III the highest value 2.13±1.11 mmol/L (range 0.62 to 4.66 mmol/L). Average cholesterol levels does not statistically significantly change with progression of chronic renal disease. There is an almost linear increase in average triglyceride levels in chronic renal disease. Triglyceride levels in serum begins to increase in the early stage of chronic renal disease and reach the peak in stage IV.

Chronic disease as risk multiplier for disadvantage.

Science.gov (United States)

Stutzin Donoso, Francisca

2018-03-06

This paper starts by establishing a prima facie case that disadvantaged groups or individuals are more likely to get a chronic disease and are in a disadvantaged position to adhere to chronic treatment despite access through Universal Health Coverage. However, the main aim of this paper is to explore the normative implications of this claim by examining two different but intertwined argumentative lines that might contribute to a better understanding of the ethical challenges faced by chronic disease health policy. The paper develops the argument that certain disadvantages which may predispose to illness might overlap with disadvantages that may hinder self-management, potentially becoming disadvantageous in handling chronic disease. If so, chronic diseases may be seen as disadvantages in themselves, describing a reproduction of disadvantage among the chronically ill and a vicious circle of disadvantage that could both predict and shed light on the catastrophic health outcomes among disadvantaged groups-or individuals-dealing with chronic disease. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Curcumin, Inflammation, and Chronic Diseases: How Are They Linked?

Directory of Open Access Journals (Sweden)

Yan He

2015-05-01

Full Text Available It is extensively verified that continued oxidative stress and oxidative damage may lead to chronic inflammation, which in turn can mediate most chronic diseases including cancer, diabetes, cardiovascular, neurological, inflammatory bowel disease and pulmonary diseases. Curcumin, a yellow coloring agent extracted from turmeric, shows strong anti-oxidative and anti-inflammatory activities when used as a remedy for the prevention and treatment of chronic diseases. How oxidative stress activates inflammatory pathways leading to the progression of chronic diseases is the focus of this review. Thus, research to date suggests that chronic inflammation, oxidative stress, and most chronic diseases are closely linked, and the antioxidant properties of curcumin can play a key role in the prevention and treatment of chronic inflammation diseases.

SECRETED KLOTHO AND CHRONIC KIDNEY DISEASE

Hu, Ming Chang; Kuro-o, Makoto; Moe, Orson W.

2013-01-01

Soluble Klotho (sKl) in the circulation can be generated directly by alterative splicing of the Klotho transcript or the extracellular domain of membrane Klotho can be released from membrane-anchored Klotho on the cell surface. Unlike membrane Klotho which functions as a coreceptor for fibroblast growth factor-23 (FGF23), sKl, acts as hormonal factor and plays important roles in anti-aging, anti-oxidation, modulation of ion transport, and Wnt signaling. Emerging evidence reveals that Klotho deficiency is an early biomarker for chronic kidney diseases as well as a pathogenic factor. Klotho deficiency is associated with progression and chronic complications in chronic kidney disease including vascular calcification, cardiac hypertrophy, and secondary hyperparathyroidism. In multiple experimental models, replacement of sKl, or manipulated up-regulation of endogenous Klotho protect the kidney from renal insults, preserve kidney function, and suppress renal fibrosis, in chronic kidney disease. Klotho is a highly promising candidate on the horizon as an early biomarker, and as a novel therapeutic agent for chronic kidney disease. PMID:22396167

The deposition patterns of aerosol inhalation scintigraphies and lung function tests were studied in 102 cases; 64 cases of obstructive pulmonary diseases (19 pulmonary emphysema, 27 diffuse panbronchiolitis, 18 chronic bronchitis) and 38 restrictive pulmonary disease (15 idiopathic interstitial pneumonia, 16 pulmonary asbestosis, 7 interstitial pneumonia due to collagen vascular disease). The deposition patterns were classified into 5 patterns (Type A:normal homogenous distribution; Type B: mildly unhomogenous distribution; Type C: severely unhomogenous distribution mingled with hot spots; Type D: non-hilar hot spots; and Type E: hilar hot spots). The deposition patterns of restrictive pulmonary diseases were markedly abnormal as well as obstructive pulmonary diseases. The deposition patterns showed mainly Types C, D and E in obstructive pulmonary diseases, Type B in restrictive pulmonary diseases. The deposition patterns showed mainly Type E in pulmonary emphysema, Types C and D in diffuse panbronchiolitis, Types A, B and C in chronic bronchitis, Type B in idiopathic interstitial pneumonia interstitial pneumonia due to collagen vascular disease, Types B and C in pulmonary asbestosis. The deposition patterns correlated well with %FEV{sub 1.0} which was a good indicator of the severity of obstructive pulmonary diseases and restrictive pulmonary diseases. Furthermore, the mean %FEV{sub 1.0} in obstructive pulmonary diseases was nearly equal to the mean %FEV{sub 1.0} in restrictive pulmonary diseases in each type of the deposition patterns. (J.P.N.).

Mortality rates for chronic lower respiratory diseases in Italy from 1979 to 2010: an age–period–cohort analysis

Full Text Available Chronic lower respiratory diseases (CLRDs are a major cause of morbidity and mortality worldwide. The objectives of this study were to estimate the trends in CLRD mortality in Italy, and the specific contributions of age, time period and birth cohort in driving these trends. Population and cause-of-death data in Italy between 1979 and 2010 were collected from the World Health Organization website. Age-specific mortality rates for CLRDs, and effects for age, time period and birth cohort on mortality trends were estimated using age–period–cohort models. Chronic obstructive pulmonary disease (COPD and chronic bronchitis represent nearly 98% of the deaths from CLRDs. Despite the overall number of deaths have been stable (in men or increasing (in women, the age-standardised rates have been steadily decreasing from 1979 to 2010, passing from 104.3 to 55.4 per 100 000 person-years in men and from 32.2 to 19.6 per 100 000 person-years in women. The average relative annual decrease was −3.6% in men and −2.7% in women. Since the end of the 1990s, the decreasing trend of CLRD mortality has started to level off, in particular in women. The decrease in CLRD mortality rates has been more accentuated in more recent cohorts and in younger age groups. Both birth cohort and time period significantly affected the CLRD mortality rates, suggesting that changes in the spread of risk factors (smoking habits, early-life and occupational exposures across different birth cohorts, as well as in advanced in healthcare and medical practice, may have played a major role in secular changes in COPD mortality rates in Italy.

Background As part of ongoing efforts to improve the Ontario health care system, a mega-analysis examining the optimization of chronic disease management in the community was conducted by Evidence Development and Standards, Health Quality Ontario (previously known as the Medical Advisory Secretariat [MAS]). Objective The purpose of this report was to identify health technologies previously evaluated by MAS that may be leveraged in efforts to optimize chronic disease management in the community. Data Sources The Ontario Health Technology Assessment Series and field evaluations conducted by MAS and its partners between January 1, 2006, and December 31, 2011. Review Methods Technologies related to at least 1 of 7 disease areas of interest (type 2 diabetes, coronary artery disease, atrial fibrillation, chronic obstructive pulmonary disease, congestive heart failure, stroke, and chronic wounds) or that may greatly impact health services utilization were reviewed. Only technologies with a moderate to high quality of evidence and associated with a clinically or statistically significant improvement in disease management were included. Technologies related to other topics in the mega-analysis on chronic disease management were excluded. Evidence-based analyses were reviewed, and outcomes of interest were extracted. Outcomes of interest included hospital utilization, mortality, health-related quality of life, disease-specific measures, and economic analysis measures. Results Eleven analyses were included and summarized. Technologies fell into 3 categories: those with evidence for the cure of chronic disease, those with evidence for the prevention of chronic disease, and those with evidence for the management of chronic disease. Conclusions The impact on patient outcomes and hospitalization rates of new health technologies in chronic disease management is often overlooked. This analysis demonstrates that health technologies can reduce the burden of illness; improve patient

Pulmonary hypertension commonly complicates chronic obstructive pulmonary disease and interstitial lung disease. The association of chronic lung disease and pulmonary hypertension portends a worse prognosis. The pathophysiology of pulmonary hypertension differs in the presence or absence of lung disease. We describe the physiological determinants of the normal pulmonary circulation to better understand the pathophysiological factors implicated in chronic parenchymal lung disease-associated pulmonary hypertension. This review will focus on the pathophysiology of 3 forms of chronic lung disease-associated pulmonary hypertension: idiopathic pulmonary fibrosis, chronic obstructive pulmonary disease, and sarcoidosis.

Framing international trade and chronic disease.

Labonté, Ronald; Mohindra, Katia S; Lencucha, Raphael

2011-07-04

There is an emerging evidence base that global trade is linked with the rise of chronic disease in many low and middle-income countries (LMICs). This linkage is associated, in part, with the global diffusion of unhealthy lifestyles and health damaging products posing a particular challenge to countries still facing high burdens of communicable disease. We developed a generic framework which depicts the determinants and pathways connecting global trade with chronic disease. We then applied this framework to three key risk factors for chronic disease: unhealthy diets, alcohol, and tobacco. This led to specific 'product pathways', which can be further refined and used by health policy-makers to engage with their country's trade policy-makers around health impacts of ongoing trade treaty negotiations, and by researchers to continue refining an evidence base on how global trade is affecting patterns of chronic disease. The prevention and treatment of chronic diseases is now rising on global policy agendas, highlighted by the UN Summit on Noncommunicable Diseases (September 2011). Briefs and declarations leading up to this Summit reference the role of globalization and trade in the spread of risk factors for these diseases, but emphasis is placed on interventions to change health behaviours and on voluntary corporate responsibility. The findings summarized in this article imply the need for a more concerted approach to regulate trade-related risk factors and thus more engagement between health and trade policy sectors within and between nations. An explicit recognition of the role of trade policies in the spread of noncommunicable disease risk factors should be a minimum outcome of the September 2011 Summit, with a commitment to ensure that future trade treaties do not increase such risks.

NAFLD and Chronic Kidney Disease.

Marcuccilli, Morgan; Chonchol, Michel

2016-04-14

Non-alcoholic fatty liver disease (NAFLD) is the most common cause of chronic liver disease in developed countries and it is now considered a risk factor for cardiovascular disease. Evidence linking NAFLD to the development and progression of chronic kidney disease (CKD) is emerging as a popular area of scientific interest. The rise in simultaneous liver-kidney transplantation as well as the significant cost associated with the presence of chronic kidney disease in the NAFLD population make this entity a worthwhile target for screening and therapeutic intervention. While several cross-sectional and case control studies have been published to substantiate these theories, very little data exists on the underlying cause of NAFLD and CKD. In this review, we will discuss the most recent publications on the diagnosis of NAFLD as well new evidence regarding the pathophysiology of NAFLD and CKD as an inflammatory disorder. These mechanisms include the role of obesity, the renin-angiotensin system, and dysregulation of fructose metabolism and lipogenesis in the development of both disorders. Further investigation of these pathways may lead to novel therapies that aim to target the NAFLD and CKD. However, more prospective studies that include information on both renal and liver histology will be necessary in order to understand the relationship between these diseases.

Exposure to biomass smoke is a risk factor for chronic obstructive pulmonary disease (COPD). It is unknown whether COPD caused by biomass smoke has different characteristics to COPD caused by tobacco smoke. To determine clinical differences between these two types of the disease. Retrospective observational study of 499 patients with a diagnosis of COPD due to biomass or tobacco smoke. The clinical variables of both groups were compared. There were 122 subjects (24.4%) in the biomass smoke group and 377 (75.5%) in the tobacco smoke group. In the tobacco group, the percentage of males was higher (91.2% vs 41.8%, P<.0001) and the age was lower (70.6 vs 76.2 years, P<.0001). Body mass index and FEV1% values were higher in the biomass group (29.4±5.7 vs 28.0±5.1, P=.01, and 55.6±15.6 vs 47.1±17.1, P<.0001, respectively). The mixed COPD-asthma phenotype was more common in the biomass group (21.3% vs 5%, P<.0001), although this difference disappeared when corrected for gender. The emphysema phenotype was more common in the tobacco group (45.9% vs 31.9%, P=.009). The prevalence of the chronic bronchitis and exacerbator phenotypes, the comorbidity burden and the rate of hospital admissions were the same in both groups. Differences were observed between COPD caused by biomass and COPD caused by tobacco smoke, although these may be attributed in part to uneven gender distribution between the groups.

Preserving kidney function and improving the transition from chronic kidney disease to end stage is a research and healthcare challenge. The national Chronic Kidney Disease-Renal Epidemiology and Information Network (CKD-REIN) cohort was established to identify the determinants, biomarkers and practice patterns associated with chronic kidney disease outcomes. The study will include more than 3000 adult patients with moderate to advanced chronic kidney disease from a representative sample of 40 nephrology clinics with respect to regions and legal status, public or private. Patients are recruited during a routine visit and followed for 5 years, before and after starting renal replacement therapy. Patient-level clinical, biological, and lifestyle data are collected annually, as well as provider-level data on clinical practices, coordinated with the International Chronic Kidney Disease Outcomes and Practice Pattern Study. Blood and urine samples are stored in a biobank. Major studied outcomes include survival, patient-reported outcomes, disease progression and hospitalizations. More than 13,000 eligible patients with chronic kidney disease were identified, 60% with stage 3 and 40% with stage 4. Their median age is 72 years [interquartile range, 62-80 years], 60% are men and 38% have diabetes. By the end of December 2015, 2885 patients were included. The CKD-REIN cohort will serve to improve our understanding of chronic kidney disease and provide evidence to improve patient survival and quality of life as well as health care system performances.

2011-05-01

Full Text Available Pneumocystis jirovecii causes pneumonia in immunosuppressed individuals. However, it has been reported the detection of low levels of Pneumocystis DNA in patients without signs and symptoms of pneumonia, which likely represents colonization. Several studies performed in animals models and in humans have demonstrated that Pneumocystis induces a local and a systemic response in the host. Since P. jirovecii colonization has been found in patients with chronic pulmonary diseases it has been suggested that P. jirovecii may play a role in the physiopathology and progression of those diseases. In this report we revise P. jirovecii colonization in different chronic pulmonary diseases such us, chronic obstructive pulmonary disease, interstitial lung diseases, cystic fibrosis and lung cancer.

Full Text Available The Chronic Obstructive Pulmonary Disease (COPD is a serious, disabling disease, presenting the pulmonary function test with abnormalities in the expiratory flow. Under this denomination, it comprises the chronic bronchitis and pulmonary emphysema. The hydrotherapy involves the physical therapy with aquatic exercises and has being used because it is a pleasant activity with positive results. The aim of this exploratory study was to compare the performance of the patients with COPD treated with hydrotherapy associated to pulmonary rehabilitation with those treated only with pulmonary rehabilitation, being held in the cardiopulmonary rehabilitation center of Messejana Hospital, in Fortaleza - Ceará. The sample consisted of 10 patients, independently of sex and age, randomly divided into two groups. The evaluation instrument was the upper limbs incremental test observing the following parameters: the cardiac frequency (FC, the respiratory frequency (f, the degree of dyspnea, the tiredness of the upper limbs, the maximum burden reached and the oxygen saturation (SatO2. The parameters FC (p=0.04, f (p=0.046 e SatO2 (p=0.008 presented an average improvement of 33.33% above those of the patients that were just in the pulmonary rehabilitation. The other evaluated parameters also presented positive results, but with p>0.05. In conclusion, the results obtained with the pulmonary rehabilitation associated to the hydrotherapy overcome those found just with the pulmonary rehabilitation treatment, allowing an increase in the physical conditioning and improvement in the functional activities; although, due to the reduced number of cases, new researches should be held to confirm this exploratory study.

A group of patients between 35 and 65 years old with chronic prostatitis were examined for the presence of Becherew's disease. In this connection the New York and Roman criterions for morbus Bechterew were applied. There were found one ankyosing spondylarthritis, one ankylosis of the sacroiliac joint, and 11 times a tentative sacroileitis were stated. Altogether the proved and tentative findings were only 3.68 per cent of all examinations. In our countries the morbus Bechterew is found in 0,21 per cent of the normal population. So the protion of the Bechterew's disease in patients with chronic prostatitis is indeed a little higher than average, but not so frequent as often pretended in recent times. After a second series 58 patients being treated because of Bechterew's disease of different stages and different terms were examined for the possibility of a simultaneously elapsing chronic prostatitis. A chronic prostatitis was found in 38 per cent of these patients which correspondents to the incidence published in literature for the medium-age manhood. Nobody of the test persons had complaints on the part of the urologenital tract.

The aim of the work was evaluation of efficacy of fenspiride b.i.d. on the number of exacerbations and the time to the first exacerbation in patients with chronic bronchitis. Randomized, multicentre study controlled versus placebo was carried out in 12 centers in Poland. All patients, 89 females and 68 males aged between 20 and 74, were treated with fenspiride at the dose of 160 mg/day for a period of 6 months. The following symptoms were recorded every month in order to evaluate the therapeutic efficacy: sputum quality and quantity, cough intensity, dyspnea and bronchospasm. Based on these symptoms diagnosis of exacerbation was performed according to American Thoracic Society criteria. Quality and quantity of sputum and cough significantly improved in the fenspiride group (comparing to the placebo group p= 0.027 and p = 0.049 adequately for sputum and cough). A significant difference between groups was observed in the number of exacerbation episodes and their duration. In the fenspiride group there were 0.53 episodes of exacerbation compared with 1.12 episodes in the placebo group (p = 0.038). Mean duration of exacerbation was 3.3 days in the fenspiride group and 7.3 days in the placebo treated patients (p = 0.034). Time to the first exacerbation differed between groups, but this difference was not statistically significant. Number of side effects observed did not differ between groups. Fenspiride treatment was assessed as relatively effective in terms of influence on exacerbations, and well tolerated during six month therapy.

Full Text Available The Kidney Disease: Improving Global Outcomes (KDIGO work group released recommendations in 2006 to define the bone-related pathology associated with chronic kidney disease as renal osteodystrophy. In 2009, KDIGO released revised clinical practice guidelines which redefined systemic disorders of bone and mineral metabolism due to chronic kidney disease as chronic kidney disease-mineral and bone disorders. Conditions under this overarching term include osteitis fibrosa cystica, osteomalacia, and adynamic bone disease. We aim to provide a brief review of the histopathology, pathophysiology, epidemiology, and diagnostic features of adynamic bone disease, focusing on current trends in the management of this complex bone disorder.

Radiology of chronic diseases of the ankle joint

Rand, T.; Trattnig, S.; Breitenseher, M.; Imhof, H.; Wagesreither, S.

1999-01-01

The etiology of chronic diseases of the ankle joint comprises a wide spectrum including chronic inflammatory processes and chronic degenerative, tumorous and neuropathic processes, as well as some specific syndromes based on chronic changes of the ankle joint. Of the inflammatory processes, chronic juvenile arthritis (JVC) is the most common disease. However, also Reiter disease, psoriasis or chronic monoarthritid diseases such as gout, as well as granulomatous diseases (tuberculosis, sarcoidosis) and fungal infections, may affect the ankle joint in a chronic course. Chronic degenerative changes are usually secondary due to abnormal positioning of the joint constituents or repetitive trauma. Neuropathic changes, as frequently seen in the course of diabetes, present with massive osseous destruction and malposition of the articular constituents. Chronic osseous as well as cartilaginous and synovial changes are seen in hemoplici patients. Chronic traumatic changes are represented by pigmented villonodular synovitis (PVNS), and chondromatosis, both with a predilection for the ankle joint. Due to the possibilities of magnetic resonance imaging (MRI), diagnosis of chronic ankle changes includes chronic ligamentous, tendinous and soft tissue changes. With the use MRI, specific syndromes can be defined which particularly affect the ankle joint in a chronic way, such as the os trigonum syndrome, the anterolateral impingement syndrome and the sinus tarsi syndrome. Nevertheless, plain film radiographs are still the basic element of any investigation. MRI, however, can be potentially used as a second investigation, saving an unnecessary cascade of investigations with ultrasound and CT. The latter investigations are used only with very specific indications, for instance CT for subtle bone structures and sonography for a limited investigation of tendons or evaluation of fluid. Particularly due to the possibilities of MRI and the development of special gradient-echo imaging or

Stem cell treatment for chronic lung diseases.

2013-01-01

Chronic lung diseases such as idiopathic pulmonary fibrosis and cystic fibrosis or chronic obstructive pulmonary disease and asthma are leading causes of morbidity and mortality worldwide with a considerable human, societal and financial burden. In view of the current disappointing status of available pharmaceutical agents, there is an urgent need for alternative more effective therapeutic approaches that will not only help to relieve patient symptoms but will also affect the natural course of the respective disease. Regenerative medicine represents a promising option with several fruitful therapeutic applications in patients suffering from chronic lung diseases. Nevertheless, despite relative enthusiasm arising from experimental data, application of stem cell therapy in the clinical setting has been severely hampered by several safety concerns arising from the major lack of knowledge on the fate of exogenously administered stem cells within chronically injured lung as well as the mechanisms regulating the activation of resident progenitor cells. On the other hand, salient data arising from few 'brave' pilot investigations of the safety of stem cell treatment in chronic lung diseases seem promising. The main scope of this review article is to summarize the current state of knowledge regarding the application status of stem cell treatment in chronic lung diseases, address important safety and efficacy issues and present future challenges and perspectives. In this review, we argue in favor of large multicenter clinical trials setting realistic goals to assess treatment efficacy. We propose the use of biomarkers that reflect clinically inconspicuous alterations of the disease molecular phenotype before rigid conclusions can be safely drawn. Copyright © 2013 S.

Full Text Available Objective: The aim is to reflect on the social and economic costs of chronic non-communicable disease (NCD in Colombia to display a charging indicator of these pathologies. Material and methods: In a review of 50 studies, 27 were selected since these met the inclusion criteria, like chronical disease, studies conducted between 2002 and 2011 related to costs, chronic disease, and being Colombian. Results: This is a review study of chronic diseases vs. their costs, being here cardiovascular diseases part of the group of high cost and higher incidence diseases, thus repre­senting a great risk to the financial stability of healthcare companies. There are few studies that address the costs generated by the treatment of ncds patients that show the economic impact experienced by public and private institutions providing and promoting health services. Most of them forget the economic, family and social costs the affected population must suffer. Conclu­sions: ncds represent a burden to the health service system for their very high costs, untimely intervention and reduced significant benefit for this population and their families.

Guidelines and standards for diagnosis and management of chronic obstructive pulmonary disease (COPD) have been presented by different national and international societies, but the spirometric criteria for COPD differ between guidelines. To estimate prevalence of COPD using the guidelines of the British Thoracic Society (BTS), the European Respiratory Society (ERS), the Global Initiative for Chronic Obstructive Lung Disease (GOLD), and the American Thoracic Society (ATS). Further, to evaluate reported airway symptoms, contacts with health care providers, and physician diagnosis of COPD in relation to the respective criteria, and gender differences. In 1992 a postal questionnaire was sent to a random sample of adults aged 20-69 years, 4,851 (85%) out of 5,681 subjects responded. In 1994-1995 a random sample of the responders, 970 subjects, were invited to a structured interview and a lung function test; 666 (69%) participated. The prevalence of COPD was 7.6, 14.0, 14.1, 12.2 and 34.1% according to BTS, ERS, GOLD, clinical ATS (with symptoms or physician diagnosis), and spirometric ATS criteria, respectively. Prevalent COPD was related to age, smoking habits and family history of obstructive airway disease but not to gender. Physician diagnosis of chronic bronchitis or emphysema was only reported by 16.3, 12.2, 11.0, 23.4 and 8.2% of subjects fulfilling the respective criteria, though a majority reported airway symptoms. The main determinants for prevalent COPD were age, smoking habits and spirometric criteria of COPD. Though a majority reported airway symptoms and contact with health care providers due to respiratory complaints, only a minority was diagnosed as having COPD, indicating a large underdiagnosis.

In Oriental countries, combinations of Chinese herbal products (CHPs) are often utilized as therapeutic agents for chronic obstructive pulmonary disease (COPD). The effects of CHPs on COPD have been previously reported. This study aimed to analyze the frequency of prescription and usage of CHPs in patients with COPD in Taiwan. In this nationwide population-based cross-sectional study, 19,142 patients from a random sample of one million individuals in the Longitudinal Health Insurance Database 2000 (LHID 2000) of the National Health Insurance Research Database (NHIRD) were enrolled from 2000 to 2011. The multiple logistic regression method was used to evaluate the adjusted odds ratios for the utilization of CHPs. For patients with COPD, there was an average of 6.31 CHPs in a single prescription. The most frequently prescribed CHP for COPD was Xiao-Qing-Long-Tang (XQLT) (2.6%), and the most commonly used combination of two formula CHPs was XQLT with Ma-Xing-Gan-Shi-Tang (MXGST) (1.28%). The most commonly used single CHP for COPD was Bulbus Fritillariae (3.65%), and the most commonly used combination of two single CHPs was Bulbus Fritillariae with Puerariae Lobatae (1.09%). These results provide information regarding personalized therapies and may promote further clinical experiments and pharmacologic research on the use of CHPs for the management of COPD. Furthermore, we found that TCM usage was more prevalent among men, younger, manual workers, residents of Northern Taiwan, and patients with chronic bronchitis and asthma. This information on the distribution of TCM usage around the country is valuable to public health policymakers and clinicians.

End-stage renal disease and dialysis is commonly associated with poor outcomes after joint replacement surgery. The goal of this study was to evaluate postoperative complications in patients with less advanced chronic kidney disease undergoing total hip arthroplasty (THA) or total knee arthroplasty (TKA). Patients who underwent THA or TKA between 2004 and 2011 with stage 1, 2, or 3 chronic kidney disease were retrospectively reviewed via an electronic medical record. The authors compared 377 patients who had stage 1 to 2 chronic kidney disease with 402 patients who had stage 3 chronic kidney disease. No significant differences in 90-day readmission or revision rates were found between the stage 1 to 2 and stage 3 patient groups. For patients with stage 3 chronic kidney disease, the overall mortality rate was greater than that in patients with stage 1 to 2 chronic kidney disease. However, when adjusted for comorbid disease, no significant increases were seen in joint infection, readmission, or early revision between patients with stage 1 to 2 chronic kidney disease vs patients with stage 3 chronic kidney disease. The overall incidence of infection was high (3.5%) but far less than reported for patients with end-stage renal disease, dialysis, and kidney transplant. In conclusion, patients with stage 1, 2, or 3 chronic kidney disease may have a higher than expected rate of prosthetic joint infection (3.5%) after total joint arthroplasty. Patients with stage 3 chronic kidney disease are at higher risk for postoperative mortality compared with those with lesser stages of kidney disease. Copyright 2014, SLACK Incorporated.

2017-04-01

Chronic traumatic encephalopathy is a neurodegenerative disease produced by accumulated minor traumatic brain injuries; no definitive premortem diagnosis and no treatments are available for chronic traumatic encephalopathy. Risk factors associated with chronic traumatic encephalopathy include playing contact sports, presence of the apolipoprotein E4, and old age. Although it shares certain histopathological findings with Alzheimer disease, chronic traumatic encephalopathy has a more specific presentation (hyperphosphorylated tau protein deposited as neurofibrillary tangles, associated with neuropil threads and sometimes with beta-amyloid plaques). Its clinical presentation is insidious; patients show mild cognitive and emotional symptoms before progressing to parkinsonian motor signs and finally dementia. Results from new experimental diagnostic tools are promising, but these tools are not yet available. The mainstay of managing this disease is prevention and early detection of its first symptoms.

Márcio Rodrigues Costa

Full Text Available ABSTRACT Purpose The study aims to assess the influence of the stage of chronic kidney disease and glomerular filtration rate on prevalence and degree of erectile dysfunction. Materials and Methods This transversal study, conducted from May 2013 to December 2015, included patients with chronic kidney disease in conservative treatment, stages III/IV/V. Erectile dysfunction was evaluated by the International Index of Erectile Function. Data classically associated with erectile dysfunction were obtained by medical record review. Erectile dysfunction, degree of erectile dysfunction, and other main variables associated with erectile dysfunction were compared between patients with chronic kidney disease on conservative treatment stages III versus IV/V using the Chi-square test. The relationship between score of the International Index of Erectile Dysfunction and glomerular filtration rate was established by Pearson correlation coefficient. Results Two hundred and forty five patients with chronic kidney disease in conservative treatment participated of the study. The prevalence of erectile dysfunction in patients with chronic kidney disease in stages IV/V was greater than in stage III. Glomerular filtration rate positively correlated with score of the International Index of Erectile Dysfunction. Conclusions The study suggests that chronic kidney disease progression (glomerular filtration rate decrease and advance in chronic kidney disease stages worsen erectile function. Hypothetically, diagnosis and treatment of erectile dysfunction may be anticipated with the analysis of chronic kidney disease progression.

Hypoglycemia is a major problem associated with substantial morbidity and mortality in patients with diabetes and is often a major barrier to achieving optimal glycemic control. Chronic kidney disease not only is an independent risk factor for hypoglycemia but also augments the risk of hypoglycemia that is already present in people with diabetes. This article summarizes our current knowledge of the epidemiology, pathogenesis, and morbidity of hypoglycemia in patients with diabetes and chronic kidney disease and reviews therapeutic considerations in this situation. PubMed and MEDLINE were searched for literature published in English from January 1989 to May 2014 for diabetes mellitus, hypoglycemia, chronic kidney disease, and chronic renal insufficiency.

Living With Chronic Lower Pulmonary Disease

Full Text Available In this article, I present a phenomenological study of individuals’ experiences of living with moderate to very severe chronic lower pulmonary disease (chronic obstructive pulmonary disease, asthma, or both. Phenomenology is a philosophy, distinct from descriptive or thematic research, which is useful as a foundation for scientific inquiry. In this study, I used the lens of Merleau-Ponty to understand and interpret participants’ experiences of living with pulmonary disease, and the approach of van Manen for analysis. I conclude that in chronic pulmonary disease, awareness of breathing and the body is experienced in the sounds, sensations, and signals of breathing and the body, and in the experiences of the body-in-the-world. Central themes of being-in-the-world from the study describe the disruption of the embodied phenomenological self: Participants experienced slowing down, doing less, and having to stop due to shortness of breath. Both chronic and acute dyspnea were prevalent and the taken-for-granted aspects of daily activities were disrupted. Findings of this study have implications for public and patient education, and opportunities for integration of experiential aspects within nursing education and practice.

The clinical presentation of chronic obstructive pulmonary disease (COPD) varies widely, so treatment must be tailored according to the level of risk and phenotype. In 2012, the Spanish COPD Guidelines (GesEPOC) first established pharmacological treatment regimens based on clinical phenotypes. These regimens were subsequently adopted by other national guidelines, and since then, have been backed up by new evidence. In this 2017 update, the original severity classification has been replaced by a much simpler risk classification (low or high risk), on the basis of lung function, dyspnea grade, and history of exacerbations, while determination of clinical phenotype is recommended only in high-risk patients. The same clinical phenotypes have been maintained: non-exacerbator, asthma-COPD overlap (ACO), exacerbator with emphysema, and exacerbator with bronchitis. Pharmacological treatment of COPD is based on bronchodilators, the only treatment recommended in low-risk patients. High-risk patients will receive different drugs in addition to bronchodilators, depending on their clinical phenotype. GesEPOC reflects a more individualized approach to COPD treatment, according to patient clinical characteristics and level of risk or complexity. Copyright © 2017 SEPAR.

Al-Shekaili, Thunai; Baylis, Matthew; Ganapathy, Kannan

2015-04-01

Infectious bronchitis virus (IBV) and avian metapneumovirus (aMPV) are economically important viral pathogens infecting chickens globally. Identification of endemic IBV and aMPV strains promotes better control of both diseases and prevents production losses. Orophrayngeal swab samples were taken from 2317 birds within 243 different backyard flocks in Oman. Swabs from each flock were examined by RT-PCR using part-S1 and G gene primers for IBV and aMPV respectively. Thirty-nine chicken flocks were positive for IBV. Thirty two of these were genotyped and they were closely related to 793/B, M41, D274, IS/1494/06 and IS/885/00. 793/B-like IBV was also found in one turkey and one duck flock. Five flocks were positive for aMPV subtype B. Though no disease was witnessed at the time of sampling, identified viruses including variant IBV strains, may still pose a threat for both backyard and commercial poultry in Oman.

To compare the demographic, socioeconomic, and medical characteristics of patients who had a General Practitioner Management Plan (GPMP) with those for patients without GPMP. Cohort study of patients with chronic diseases during the time period 1 July 2006 to 30 June 2008 using the Australian Department of Veterans' Affairs (DVA) claims database. Of the 88 128 veterans with chronic diseases included in the study, 23 015 (26%) veterans had a GPMP and 11 089 (13%) had a Team Care Arrangement (TCA). Those with a GPMP had a higher number of comorbidities (P<0.001), and a higher use of services such as health assessment and medicine review (P<0.001) than did those without GPMP. Diabetes was associated with a significantly increased use of GPMP compared with all other chronic diseases except heart failure. GPMPs are used in a minority of patients with chronic diseases. Use is highest in people with diabetes.

A substantial proportion of chronic disease patients do not respond to self-management interventions, which suggests that one size interventions do not fit all, demanding more tailored interventions. To compose more individualized strategies, we aim to increase our understanding of characteristics associated with patient activation for self-management and to evaluate whether these are disease-transcending. A cross-sectional survey study was conducted in primary and secondary care in patients with type-2 Diabetes Mellitus (DM-II), Chronic Obstructive Pulmonary Disease (COPD), Chronic Heart Failure (CHF) and Chronic Renal Disease (CRD). Using multiple linear regression analysis, we analyzed associations between self-management activation (13-item Patient Activation Measure; PAM-13) and a wide range of socio-demographic, clinical, and psychosocial determinants. Furthermore, we assessed whether the associations between the determinants and the PAM were disease-transcending by testing whether disease was an effect modifier. In addition, we identified determinants associated with low activation for self-management using logistic regression analysis. We included 1154 patients (53% response rate); 422 DM-II patients, 290 COPD patients, 223 HF patients and 219 CRD patients. Mean age was 69.6±10.9. Multiple linear regression analysis revealed 9 explanatory determinants of activation for self-management: age, BMI, educational level, financial distress, physical health status, depression, illness perception, social support and underlying disease, explaining a variance of 16.3%. All associations, except for social support, were disease transcending. This study explored factors associated with varying levels of activation for self-management. These results are a first step in supporting clinicians and researchers to identify subpopulations of chronic disease patients less likely to be engaged in self-management. Increased scientific efforts are needed to explain the greater

1988-11-01

Thirty subjects with severe chronic obstructive airways disease participated in a study to identify differences in symptoms and life quality between those with high and low emergent use of institutional health care resources. Emergent use was defined as care obtained through unscheduled, nonroutine methods of access to health care providers. There were 15 subjects in each group; the groups had similar sex distribution and were not significantly different for percent predicted forced expiratory volume in 1 second (mean 29.8%), use of home oxygen (15 of 30 subjects), or prevalence of CO2 retention (nine of 30). Symptoms and life quality were measured by using three paper and pencil tests, the Bronchitis-Emphysema Symptom Checklist, the Sickness-Impact Profile, and the Katz Adjustment Scale for relatives. Findings demonstrated consistently more symptoms and impairment of life quality in the "high emergent" group. The differences reached statistical significance for irritability, anxiety, helplessness, nervousness, peripheral sensory complaints, alienation, social interaction, and emotional behavior. Discriminant analysis provided a prediction formula that yielded 80% correct prediction for the two groups.

Interactions between live Newcastle disease virus (NDV), avian metapneumovirus (aMPV) and infectious bronchitis virus (IBV) vaccines following simultaneous vaccination of day old specific pathogen free (SPF) chicks were evaluated. The chicks were divided into eight groups: seven vaccinated against NDV, aMPV and IBV (single, dual or triple) and one unvaccinated as control. Haemagglutination inhibition (HI) NDV antibody titres were similar across all groups but were above protective titres. aMPV vaccine when given with other live vaccines suppressed levels of aMPV enzyme-linked immunosorbent assay (ELISA) antibodies. Cellular and local immunity induced by administration of NDV, aMPV or IBV vaccines (individually or together) showed significant increase in CD4+, CD8+ and IgA bearing B-cells in the trachea compared to the unvaccinated group. Differences between the vaccinated groups were insignificant. Simultaneous vaccination with live NDV, aMPV and IBV did not affect the protection conferred against aMPV or IBV.

Household food insecurity has been previously hypothesized to promote dependence on inexpensive, highly palatable foods that are energy dense. Such dependence, and the cyclical nature of having enough food in the beginning of the month followed by food scarcity at the end of the month, could lead to weight gain over a short period of time. Such dependence on energy-dense foods and weight gain may play a direct role in the development of chronic conditions. Other compounding factors that result from exposure to household food insecurity have been well described, including pathways by which stress promotes visceral fat accumulation and chronic disease. This symposium review paper summarizes the literature on the link between food insecurity and the following: 1) diet, 2) weight gain, and 3) chronic disease, especially among women. This paper also proposes a framework for considering how the lived experience of household food insecurity may potentiate the development of chronic disease by activating the stress response among individuals at critical developmental periods in a food-impoverished environment.

Most patients with COPD rely on primary care practices for COPD management. Unfortunately, only about 55% of US outpatients with COPD receive all guideline-recommended care. Proactive and consistent primary care for COPD, as for many other chronic diseases, can reduce hospitalizations. Optimal chronic disease management requires focusing on maintenance rather than merely acute rescue. The Patient-Centered Medical Home (PCMH, which implements the chronic care model, is a promising framework for primary care transformation.

Growth failure is a common problem in many children with chronic diseases. This article is an overview of the most common causes of growth failure/growth retardation that affect children with a number of chronic diseases. We also briefly review the nutrition considerations and treatment goals. Growth failure is multifactorial in children with chronic conditions, including patients with cystic fibrosis, chronic kidney disease, chronic liver disease, congenital heart disease, human immunodeficiency virus, inflammatory bowel disease, short bowel syndrome, and muscular dystrophies. Important contributory factors to growth failure include increased energy needs, increased energy loss, malabsorption, decreased energy intake, anorexia, pain, vomiting, intestinal obstruction, and inflammatory cytokines. Various metabolic and pathologic abnormalities that are characteristic of chronic diseases further lead to significant malnutrition and growth failure. In addition to treating disease-specific abnormalities, treatment should address the energy and protein deficits, including vitamin and mineral supplements to correct deficiencies, correct metabolic and endocrinologic abnormalities, and include long-term monitoring of weight and growth. Individualized, age-appropriate nutrition intervention will minimize the malnutrition and growth failure seen in children with chronic diseases. © 2014 American Society for Parenteral and Enteral Nutrition.

Pesticides and human chronic diseases: Evidences, mechanisms, and perspectives

Along with the wide use of pesticides in the world, the concerns over their health impacts are rapidly growing. There is a huge body of evidence on the relation between exposure to pesticides and elevated rate of chronic diseases such as different types of cancers, diabetes, neurodegenerative disorders like Parkinson, Alzheimer, and amyotrophic lateral sclerosis (ALS), birth defects, and reproductive disorders. There is also circumstantial evidence on the association of exposure to pesticides with some other chronic diseases like respiratory problems, particularly asthma and chronic obstructive pulmonary disease (COPD), cardiovascular disease such as atherosclerosis and coronary artery disease, chronic nephropathies, autoimmune diseases like systemic lupus erythematous and rheumatoid arthritis, chronic fatigue syndrome, and aging. The common feature of chronic disorders is a disturbance in cellular homeostasis, which can be induced via pesticides' primary action like perturbation of ion channels, enzymes, receptors, etc., or can as well be mediated via pathways other than the main mechanism. In this review, we present the highlighted evidence on the association of pesticide's exposure with the incidence of chronic diseases and introduce genetic damages, epigenetic modifications, endocrine disruption, mitochondrial dysfunction, oxidative stress, endoplasmic reticulum stress and unfolded protein response (UPR), impairment of ubiquitin proteasome system, and defective autophagy as the effective mechanisms of action. - Highlights: ► There is a link between exposure to pesticides and incidence of chronic diseases. ► Genotoxicity and proteotoxicity are two main involved mechanisms. ► Epigenetic knowledge may help diagnose the relationships. ► Efficient policies on safe use of pesticides should be set up

Precision medicine for managing chronic diseases.

Śliwczynski, Andrzej; Orlewska, Ewa

2016-08-18

Precision medicine (PM) is an important modern paradigm for combining new types of metrics with big medical datasets to create prediction models for prevention, diagnosis, and specific therapy of chronic diseases. The aim of this paper was to differentiate PM from personalized medicine, to show potential benefits of PM for managing chronic diseases, and to define problems with implementation of PM into clinical practice. PM strategies in chronic airway diseases, diabetes, and cardiovascular diseases show that the key to developing PM is the addition of big datasets to the course of individually profiling diseases and patients. Integration of PM into clinical practice requires the reengineering of the health care infrastructure by incorporating necessary tools for clinicians and patients to enable data collection and analysis, interpretation of the results, as well as to facilitate treatment choices based on new understanding of biological pathways. The size of datasets and their large variability pose a considerable technical and statistical challenge. The potential benefits of using PM are as follows: 1) broader possibilities for physicians to use the achievements of genomics, proteomics, metabolomics, and other "omics" disciplines in routine clinical practice; 2) better understanding of the pathogenesis and epidemiology of diseases; 3) a revised approach to prevention, diagnosis, and treatment of chronic diseases; 4) better integration of electronic medical records as well as data from sensors and software applications in an interactive network of knowledge aimed at improving the modelling and testing of therapeutic and preventative strategies, stimulating further research, and spreading information to the general public.

Rural-urban differences in the prevalence of chronic diseases in the adult population of northeast China are examined. The Jilin Provincial Chronic Disease Survey used personal interviews and physical measures to research the presence of a range of chronic diseases among a large sample of rural and urban provincial residents aged 18 to 79 years (N = 21 435). Logistic regression analyses were used. After adjusting for age and gender, rural residents had higher prevalence of hypertension, chronic ischemic heart disease, cerebrovascular disease, chronic low back pain, arthritis, chronic gastroenteritis/peptic ulcer, chronic cholecystitis/gallstones, and chronic lower respiratory disease. Low education, low income, and smoking increased the risk of chronic diseases in rural areas. Reducing rural-urban differences in chronic disease presents a formidable public health challenge for China. The solution requires focusing attention on issues endemic to rural areas such as poverty, lack of chronic disease knowledge, and the inequality in access to primary care. © 2014 APJPH.

Chronic obstructive pulmonary disease is the fourth leading cause of mortality worldwide. It is defined as a persistent airflow limitation usually progressive and not fully reversible to treatment. The diagnosis of chronic obstructive pulmonary disease and severity of disease is confirmed by spirometry. Chronic obstructive pulmonary disease produces electrical changes in the heart which shows characteristic electrocardiogram pattern. The aim of this study was to observe and evaluate diagnostic values of electrocardiogram changes in chronic obstructive pulmonary disease patients with no other comorbidity. We analyzed 110 electrocardiogram findings in clinically stable chronic obstructive pulmonary disease patients and evaluated the forced expiratory volume in the first second, ratio of forces expiratory volume in the first second to the fixed vital capacity, chest radiographs and electrocardiogram changes such as p wave height, QRS axis and voltage, right bundle branch block, left bundle branch block, right ventricular hypertrophy, T wave inversion in leads V1-V3, S1S2S3 syndrome, transition zone in praecordial lead and QT interval. We found electrocardiogram changes in 64% patients, while 36% had normal electrocardiogram. The most frequent electrocardiogram changes observed were transition zone (76.36%) low QRS (50%) and p pulmonale (14.54%). Left axis deviation was observed in 27.27% patients. Diagnostic values of electrocardiogram in patients with chronic obstructive pulmonary disease suggest that chronic obstructive pulmonary disease patients should be screened electrocardiographically in addition to other clinical investigations.

To examine the variations in the prevalence of skin reactions and the association between skin reactions and efficacy of summer acupoint application treatment (SAAT) on chronic pulmonary disease (CPD). A total of 2,038 patients with CPD were enrolled at 3 independent hospitals (defined as Groups A, B and C, respectively) in China. All patients were treated by SAAT, as applying a herbal paste onto the acupoints of Fengmen (BL 12) and Feishu (BL 13) on the dog days of summer, according to the lunar calendar, in 2008. Ten days after treatment, skin reaction data (no reaction, itching, stinging, blistering, and infection) were obtained via face-to-face interviews. Patients were retreated in the same hospital one year later, thereby allowing doctors to assess treatment efficacy based on the patients' symptoms, the severity of the spirometric abnormalities, and the concomitant medications used. A large number of patients (85.3%) displayed reactive symptoms; however, the marked associations between reactive symptoms and age or gender were not observed. An increased number of patients from Group B (99.3%) and Group C (76.5%) displayed reactive symptoms due to the increased mass of crude Semen Sinapis Albae. The effective rate of SAAT was as high as 90.4% for patients of Group B, which was followed by Group A (70.9%) and Group C (42.2%). Using stratified analyses, a convincing association between reactive symptoms and therapeutic efficacy was observed for patients with asthma [itching: odds ratio (OR)=2.17, 95% confidence interval (CI): 1.49 to 3.14; blistering: OR=0.43, 95% CI: 0.25 to 0.73; and no reaction: OR=0.56, 95% CI: 0.35 to 0.90]. However, the same tendency was not observed for patients with chronic bronchitis and chronic obstructive pulmonary disease. SAAT can induce very mild skin reactions for patients with CPD, among which patients with asthma displayed a strong association between skin reactions and therapeutic efficacy. The skin reactions may be induced by

Clinical onset of chronic obstructive pulmonary disease (COPD) is the point at which the disease is first identifiable by physicians. It is a poorly defined stage which seems to include both mild spirometric and non-spirometric disease, and could be described as early grade COPD, for practical purposes. While dyspnoea; chronic bronchitis and CT imaging evidence of emphysema and airway disease may be present very early, the lone significance of dyspnoea, the most relevant symptom in COPD in identifying these individuals, has been scarcely assessed.The Searching Clinical COPD Onset (SOON) Study was designed primarily to detect clinical, physiological and structural differences between dyspnoeic and non-dyspnoeic individuals with early grade COPD. It is hypothesised that presence of dyspnoea in early disease may identify a subtype of individuals with reduced exercise capacity, notwithstanding of their spirometry results. In addition, dyspnoeic individuals will share worse quality of life, lower physical activity, greater lung hyperinflation greater emphysema and airway thickness and reduced peripheral muscle mass than their non-dyspnoeic counterpart. SOON is a monocentric study, with a cross sectional design aimed at obtaining representative samples of current or ex-smoker-adults aged ≥45 and ≤80 years. Two hundred and forty participants will be enrolled into four strata, according to normal spirometry or mild spirometric obstruction and presence or not of dyspnoea modified Medical Research Council score ≥1. The primary outcome will be the difference between dyspnoeic and non-dyspnoeic individuals on the 6-min walk test performance, regardless of their spirometry results. To account for the confounding effect of heart failure on dyspnoea, stress echocardiography will be also performed. Secondary outcomes will include clinical (quality of life, physical activity), physiological (exercise testing) and structural characteristics (emphysema, airway disease and

Saudi demographic composition has changed because of increased life expectancy and decreased fertility rates. Little data are available about health conditions among older adults in Saudi Arabia, who are expected to represent 20% of the population by 2050. The study aim was to assess the prevalence and risk factors for chronic conditions among older Saudi men. The sample pertained to 400 men (age ≥55 years) from Buraidah, Al-Qassim. Research assistants recruited participants in all the mosques from the randomly selected neighborhoods (16 of 95). They administered a structured questionnaire that assessed self-reported disease history (heart disease, hypertension, diabetes, asthma, gastric/peptic ulcer, and cancer), and medication use; participants' height, weight, blood pressure, and random blood glucose (glucometer) were measured. Multinomial logistic regressions were employed to assess correlates of number of chronic diseases. The mean and standard deviation for age and body mass index (BMI) were 63.0 ± 7.5 years and 28.9 ± 4.8 (kg/m 2 ), respectively. 78% (77.8%) were overweight or obese, 35.0% were employed, 54.5% walked daily, 9.3% were current smokers, and 85.0% belonged to the middle class. The prevalence of hypertension, diabetes, heart disease, asthma, ulcer, and cancer were: 71.3% 27.3%, 16.4%, 9.7%, 8.9%, and 2.0%, respectively. Of the participants, 31.0% had one, 34.5% had two or more, and 34.5% did not have any chronic diseases. The likelihood of chronic diseases increased with increased age, higher BMI, and current smoking. The chronic disease prevalence among the Saudi elderly men is substantial.

Abstract The aim of this study is to explore whether there is a relationship between chronic pancreatitis and cerebrovascular disease in Taiwan. Using the claims data of the Taiwan National Health Insurance Program, we identified 16,672 subjects aged 20 to 84 years with a new diagnosis of chronic pancreatitis from 2000 to 2010 as the chronic pancreatitis group. We randomly selected 65,877 subjects aged 20 to 84 years without chronic pancreatitis as the nonchronic pancreatitis group. Both groups were matched by sex, age, comorbidities, and the index year of diagnosing chronic pancreatitis. The incidence of cerebrovascular disease at the end of 2011 was measured. The multivariable Cox proportional hazards regression model was used to measure the hazard ratio (HR) and 95% confidence interval (CI) for cerebrovascular disease risk associated with chronic pancreatitis and other comorbidities. The overall incidence of cerebrovascular disease was 1.24-fold greater in the chronic pancreatitis group than that in the nonchronic pancreatitis group (14.2 vs. 11.5 per 1000 person-years, 95% CI = 1.19–1.30). After controlling for confounding factors, the adjusted HR of cerebrovascular disease was 1.27 (95% CI = 1.19–1.36) for the chronic pancreatitis group as compared with the nonchronic pancreatitis group. Woman (adjusted HR = 1.41, 95% CI = 1.31–1.51), age (every 1 year, HR = 1.04, 95% CI = 1.04–1.05), atrial fibrillation (adjusted HR = 1.23, 95% CI = 1.02–1.48), chronic kidney disease (adjusted HR = 1.48, 95% CI = 1.31–1.67), chronic obstructive pulmonary disease (adjusted HR = 1.27, 95% CI = 1.16–1.40), diabetes mellitus (adjusted HR = 1.82, 95% CI = 1.72–1.92), hypertension (adjusted HR = 1.66, 95% CI = 1.56–1.76), and peripheral atherosclerosis (adjusted HR = 1.26, 95% CI = 1.06–1.51) were other factors significantly associated with cerebrovascular disease.

Full Text Available Chagas disease is an infectious disease caused by the protozoan Trypanosoma cruzi. The disease mainly affects the nervous system, digestive system and heart. The objective of this review is to revise the literature and summarize the main chronic gastrointestinal manifestations of Chagas disease. The chronic gastrointestinal manifestations of Chagas disease are mainly a result of enteric nervous system impairment caused by T. cruzi infection. The anatomical locations most commonly described to be affected by Chagas disease are salivary glands, esophagus, lower esophageal sphincter, stomach, small intestine, colon, gallbladder and biliary tree. Chagas disease has also been studied in association with Helicobacter pylori infection, interstitial cells of Cajal and the incidence of gastrointestinal cancer.

Full Text Available Respiratory diseases, always being a threat towards the health of people all over the world, are most tightly associated with immune system. Neutrophils serve as an important component of immune defense barrier linking innate and adaptive immunity. They participate in the clearance of exogenous pathogens and endogenous cell debris and play an essential role in the pathogenesis of many respiratory diseases. However, the pathological mechanism of neutrophils remains complex and obscure. The traditional roles of neutrophils in severe asthma, chronic obstructive pulmonary diseases (COPD, pneumonia, lung cancer, pulmonary fibrosis, bronchitis, and bronchiolitis had already been reviewed. With the development of scientific research, the involvement of neutrophils in respiratory diseases is being brought to light with emerging data on neutrophil subsets, trafficking, and cell death mechanism (e.g., NETosis, apoptosis in diseases. We reviewed all these recent studies here to provide you with the latest advances about the role of neutrophils in respiratory diseases.

Triumph and tragedy: anemia management in chronic kidney disease.

Novak, James E; Szczech, Lynda A

Recent trial data have resulted in a reevaluation of the management of anemia in chronic kidney disease, including the use of erythropoiesis-stimulating agents, intravenous iron, and novel pharmaceuticals. In this review, we evaluate the latest research on anemia management in chronic kidney disease. Clinical trials of erythropoiesis-stimulating agents indicate that targeting the complete correction of anemia in patients with chronic kidney disease results in a greater risk of morbidity and mortality despite improved hemoglobin and quality of life. Conversely, intravenous iron has been found effective and relatively well tolerated in treating anemia in chronic kidney disease, even in patients with elevated ferritin. New agents to manage anemia, including long-acting erythropoietin derivatives, are also in active development. Erythropoiesis-stimulating agents should be used to target hemoglobin 11-12 g/dl in patients with chronic kidney disease. Intravenous iron may be beneficial for patients with hemoglobin less than 11 g/dl and transferrin saturation less than 25% despite elevated ferritin (500-1200 ng/ml). An upcoming placebo-controlled trial of darbepoetin should help to define the role of erythropoiesis-stimulating agents in chronic kidney disease.

To explore the relationship between daytime napping and incidence of chronic diseases over the past 6 months among adults in China. Based on data collected from 13,469 respondents over age 40 in the Chinese Family Panel Studies in 2010, logistic regression models were estimated to examine the association between daytime napping and the incidence of any chronic diseases and 3 specific chronic diseases (hypertension, diabetes, and heart disease) after adjusting for confounders. Differences of risks by sex and age were also investigated. In the sample, 50.8% were women and 32.2% were over 60 years old. Adjusted estimates show respondents with daytime napping had elevated odds of developing any chronic diseases, hypertension, and diabetes compared to those who did not nap; having over 60 minutes of daytime napping had weaker association compared with shorter duration of daytime napping. The association between daytime napping and hypertension was found in women but not in men. Daytime napping appears to be associated with elevated risk of incidence of any chronic diseases, hypertension, and diabetes.

Full Text Available Background . Chronic kidney disease (CKD is at present a worldwide health problem. According to the National Kidney Foundation Kidney Disease Outcomes Quality Initiative (NKF KDOQI, chronic kidney disease has five stages of advancement based on the estimated glomerular filtration rate (eGFR. The formulas that are most frequently used in determining eGFR are the Cockroft–Gault (CG formula, the simplified Modification of Diet in Renal Disease (MDRD formula, and the Chronic Kidney Disease Epidemiology (CKD-EPI Collaboration formula, which is considered the most accurate formula. Objectives . The aim of our study was to compare the CG, simplified MDRD and CKD-EPI formulas for determining eGFR and thus CKD advancement. Material and methods. The study was conducted on a group of 202 patients with previously diagnosed CKD. To calculate the eGFR, the CG, simplified MDRD, and CKD-EPI formulas were used. Patients were assigned a disease stage (from 1 to 5 according to the NKF KDOQI guidelines. Results . The calculated eGFR values varied depending on the formula, which resulted different assignations of patients to CKD stages. The largest difference regarded the qualification of the patients to the first and the fifth stage. A similar number of patients were classed as stage three by all formulas. Differences were also seen in how the formulas classified patients to the second and fourth stages. Conclusions . GFR estimation remains a problematic clinical concern. The CKD stage assigned to patients varies depending on the formula used, a fact which may be particularly significant for general practitioners. Laboratories should apply the CKD-EPI formula for eGFR calculation, as it gives the least false results.

Full Text Available Aim: The purpose of our study is to study the etiopathogenesis of periodontitis in chronic kidney disease and to identify a correlation between periodontitis and chronic kidney disease, with the help of periodontal exaamination, ultrasonographic and hematobiochemical analysis. Materials and Methods: 46 dogs with renal failure were studied and classified as presenting a slight (56.52%, moderate (36.95% and severe (47.8% degree of periodontal disease. Results: Marked gingival recession involving whole maxillary dental arcade, Oral mucosa ulcers and tissue necrosis and mobility of mandibular incisors was observed in dogs with chronic kidney disease. Dogs with normal renal function were observed to have minimal gingival recession of the mandibular teeth only. Conclusion: In view of the causative association between periodontal infection, generalized inflammation and important systemic diseases like chronic kidney disease, we hypothesize that targeted prophylaxis and careful treatment of oral diseases can prevent the progression of renal failure

Burton, Janet; Murphy, Elyse; Riley, Patty

2010-01-01

Patient-centered chronic care management is a new model for the management of rare chronic diseases such as primary immunodeficiency disease (PIDD). This approach emphasizes helping patients become experts on the management of their disease as informed, involved, and interactive partners in healthcare decisions with providers. Because only a few patients are affected by rare illnesses, these patients are forced to become knowledgeable about their disease and therapies and to seek treatment from a healthcare team, which includes physicians and nurse specialists who are equipped to manage the complexity of the disease and its comorbidities. Importantly, therapy for PIDD can be self-administered at home, which has encouraged the transition toward a proactive stance that is at the heart of patient-centered chronic care management. We discuss the evolution of therapy, the issues with the disease, and challenges with its management within the framework of other chronic disease management programs. Suggestions and rationale to move case management of PIDD forward are presented with the intent that sharing our experiences will improve process and better manage outcomes in this patient population. The patient-centered model for the management of PIDD is applicable to the primary care settings, where nurse case managers assist patients through education, support them and their families, and facilitate access to community resources in an approach, which has been described as "guided care." The model also applies specifically to immunology centers where patients receive treatment or instruction on its self-administration at home. Patient-centered management of PIDD, with its emphasis on full involvement of patients in their treatment, has the potential to improve compliance with treatment, and thus patient outcomes, as well as patients' quality of life. The patient-centered model expands the traditional model of chronic disease management, which relies on evidence

Tahir, A.; Malik, F.R.; Akhtar, P.

2011-01-01

Background: Chronicity of liver disease is determined either by duration of liver disease or by evidence of either severe liver disease or physical stigmata of chronic liver disease. Chronic liver disease may be caused commonly by persistent viral infections, metabolic diseases, drugs, autoimmune hepatitis, or unknown factors. The objective of this study was to find out the aetiology of chronic liver disease (CLD) in children. Methodology: It was a descriptive, prospective study which used a structured proforma designed to collect data of cases of CLD from both indoor and outdoor Paediatrics units of Fauji Foundation Hospital, Rawalpindi, and Children Hospital, Pakistan Institute of Medical Sciences, Islamabad. All children under 12 years having either clinical or biochemical evidence of liver disease and/or elevated liver enzymes for more than 3 months were included in this study. Results: Sixty cases of CLD were enrolled from indoor and outdoor units from January 2010 to July 201. Thirty nine (65%) cases were male and 21 (35%) were female. Eleven children were less than 1 year, 18 were 1-5 years old and 31 were 5-12 years of age. Viral hepatitis was the most common cause found in 22 (36.7%) cases. Out of these 22 patients with viral aetiology 19 (31.66%) patients had Hepatitis C and 3 (5%) had Hepatitis B. Glycogen storage disease was seen in 8.3% cases, and biliary atresia and Wilson disease in 6.7% each. Other less commonly found cases were autoimmune hepatitis, TORCH infections, hepatoma and drug induced hepatitis (1.7% each). Cause couldn't be established in 35% cases which remained idiopathic. Conclusion: Viral hepatitis is the leading cause of chronic liver disease in children, with the highest incidence of chronic Hepatitis C followed by metabolic disorders (glycogen storage disease and Wilson disease) and biliary atresia. Chronic viral hepatitis was most prevalent between 11 months to 12 years of age. Wilson disease was common in 3-7 years age group, and

Perfusion scintigraphy, radioaerosol inhalation scintigraphy, /sup 133/Xe studies and sup(81m)Kr studies are useful radioisotope techniques for the detection of regional pulmonary abnormalities in obstructive airway disease. The patient during asthmatic attack shows the perfusion defects with indefinite boundary, which may change during the following several days. Decreased ventilation are seen on the regions with perfusion defects, and ventilatory defects are more marked than those of perfusion. On the other hand, these abnomal findings are reversible. In chronic emphysema or chronic bronchitis, the regions with decreased perfusion usually cannot be correlated with any specific segments, and scintigraphys done repeatedly fail to show re-vascularization on the regions. In the radioaerosol inhalation scintigraphy, deposition pattern reveal the severity of COPD. In addition, xenon studies in the diseases show marked or moderate prolongation of wash-out from the abnormal region, and the abnormalities of ventilation are equal to or exceed the abnormalities of perfusion.

Full Text Available The occurrence of depression is higher in patients with chronic liver disease (CLD than that in the general population. The mechanism described in previous studies mainly focused on inflammation and stress, which not only exists in CLD, but also emerges in common chronic diseases, leaving the specific mechanism unknown. This review was to summarize the prevalence and risk factors of depression in CLD including chronic hepatitis B, chronic hepatitis, alcoholic liver disease, and non-alcoholic fatty liver disease, and to point out the possible underlying mechanism of this potential link. Clarifying the origins of this common comorbidity (depression and CLD may provide more information to understand both diseases.

Full Text Available BACKGROUND: People all around the world are more concerned with living a long and healthy life, rather than just living longer. Many studies have examined the effects of lifestyle on the risk of developing chronic diseases, but typically, they focus on only one specific behavior. Individuals often follow a lifestyle pattern which combines more than one behavior. This paper examines the combined effect of several lifestyle factors on the number of chronic diseases.OBJECTIVE: The goal of this study was to determine how different lifestyle factors influence the number of chronic diseases a person can have.METHODS: Data from the survey “Health and Well-being in the Transitions” (2000 were used. Dependent variable was number of chronic diseases which ranged from zero to five. Independent variables included the level of physical activity, variables based on food frequency questions, and other behavioral activities, adjusted for age and gender. Generalized linear model with Poisson distribution was used for analysis.RESULTS: The analysis showed that males have more diseases than females if other factors are controlled (B=0.182, p=0.001. Diseases increase by age (B=0.021, p=0.000. Those who used dairy products daily had smaller number of diseases (B= -0.145, p=0.012. Those who used vegetable oil 3-7 days a week had smaller number of diseases than those who use it 0-2 days a week (B= -0.224, p=0.058. Other food frequencies and ever smoking had no clear association with number of diseases.CONCLUSION: Increasing age and male gender are two factors which are associated with larger number of chronic diseases. Regular use of vegetable oil and dairy products seems to be important towards the path of a healthier life.

Chronic parotitis is a troubling clinical condition characterized by repeated infection and inflammation of the parotid gland caused by decreased salivary flow or obstruction. Unilateral swelling, pain, and other associated symptoms occur during acute exacerbations of the disease. A variety of laboratory and radiographic tools are available to aid in the diagnosis. Multiple treatment options have been proposed, ranging from conservative medical management to surgical interventions. We present 2 patients with bilateral chronic parotitis who attempted prolonged medical management and ultimately required surgical parotidectomy for control of their disease.

[The effects of air pollution and climate change on pulmonary diseases].

Science.gov (United States)

Rohde, G

2008-04-01

From as early as 1930 there has been evidence for effects on health of air pollution. Ozone, particulates and nitrogen dioxide are the most important pollutants today. The acute increase in air pollution leads to a significant raise in morbidity and mortality. Hospital admissions of patients with chronic obstructive pulmonary disease (COPD) or asthma are more frequent during these periods. Chronic exposure to pollution causes bronchitis, accelerated decline of lung function and impaired maturing of the lungs. Ozone and a residence in proximity to major roads seem to play a role in the development of asthma. A further important environmental factor is climate change, which has an impact on air pollution but also on distribution and quality of aero-allergens and the dissemination and transmission of respiratory pathogens.

Tackling Africa's chronic disease burden: from the local to the global

Full Text Available Abstract Africa faces a double burden of infectious and chronic diseases. While infectious diseases still account for at least 69% of deaths on the continent, age specific mortality rates from chronic diseases as a whole are actually higher in sub Saharan Africa than in virtually all other regions of the world, in both men and women. Over the next ten years the continent is projected to experience the largest increase in death rates from cardiovascular disease, cancer, respiratory disease and diabetes. African health systems are weak and national investments in healthcare training and service delivery continue to prioritise infectious and parasitic diseases. There is a strong consensus that Africa faces significant challenges in chronic disease research, practice and policy. This editorial reviews eight original papers submitted to a Globalization and Health special issue themed: "Africa's chronic disease burden: local and global perspectives". The papers offer new empirical evidence and comprehensive reviews on diabetes in Tanzania, sickle cell disease in Nigeria, chronic mental illness in rural Ghana, HIV/AIDS care-giving among children in Kenya and chronic disease interventions in Ghana and Cameroon. Regional and international reviews are offered on cardiovascular risk in Africa, comorbidity between infectious and chronic diseases and cardiovascular disease, diabetes and established risk factors among populations of sub-Saharan African descent in Europe. We discuss insights from these papers within the contexts of medical, psychological, community and policy dimensions of chronic disease. There is an urgent need for primary and secondary interventions and for African health policymakers and governments to prioritise the development and implementation of chronic disease policies. Two gaps need critical attention. The first gap concerns the need for multidisciplinary models of research to properly inform the design of interventions. The second

Fabry's disease is an X-linked inherited, rare, progressive, lysosomal storage disorder, affecting multiple organs due to the deficient activity of α-galactosidase A (α-Gal A) enzyme. The prevalence has been reported to be 0.15-1% in hemodialysis patients; however, the information on the prevalence in chronic kidney disease not on dialysis is lacking. This study aimed to determine the prevalence of Fabry's disease in chronic kidney disease. The patients older than 18 years, enclosing KDIGO 2012 chronic kidney disease definitions, not on dialysis, were enrolled. Dried blood spots on Guthrie papers were used to analyze α-Gal A enzyme and genetic analysis was performed in individuals with enzyme activity ≤1.2 μmol/L/h. A total of 1453 chronic kidney disease patients not on dialysis from seven clinics in Turkey were screened. The mean age of the study population was 59.3 ± 15.9 years. 45.6% of patients were female. The creatinine clearance of 77.3% of patients was below 60 mL/min/1.73 m 2 , 8.4% had proteinuria, and 2.5% had isolated microscopic hematuria. The mean value of patients' α-Gal A enzyme was detected as 2.93 ± 1.92 μmol/L/h. 152 patients had low levels of α-Gal A enzyme activity (≤1.2 μmol/L/h). In mutation analysis, A143T and D313Y variants were disclosed in three male patients. The prevalence of Fabry's disease in chronic kidney disease not on dialysis was found to be 0.2% (0.4% in male, 0.0% in female). Fabry's disease should be considered in the differential diagnosis of chronic kidney disease with unknown etiology even in the absence of symptoms and signs suggestive of Fabry's disease.

E-mail: elmiro@vm.uff.br Avian infectious bronchitis (IB is a viral, acute and highly contagious disease caused by infectious bronchitis virus (IBV. The disease affects broilers improvement and performance causing major economic losses in the world poultry industry. Generally, IBV infections can be diagnosed by detection of IBV itself or the specific antibody response. This study aimed to detect IBV in broilers under Sanitary Inspection by RT-PCR and ELISA, comparing the results and relating them with the average weight of the flock. Samples were collected from 40 vaccinated broiler flocks under Sanitary Inspection at slaughter. Ten birds from every flock were randomly selected and blood samples were collected for ELISA as well three birds had their trachea and caecal tonsils collected for RT- -PCR test. From 40 flocks, 30 were IBV positive by ELISA and 26 by RT-PCR, in which 15 were detected simultaneously in trachea and caecal tonsil and 5 in each sample. There was no agreement between ELISA and RT-PCR results regarding IBV diagnosis as well positivity in both tests was not statistically significant with the average weight of the flock. There was an improvement on IBV diagnosis when caecal tonsils and tracheas were used instead of just one of them. Considering the only vaccine serotype allowed by Brazilian government is the Mass serotype and its persistence in broilers would only be detected up to 28 days

Chronic viral liver disease is often associated with other conditions. Diabetes mellitus (DM) is frequently reported in this context and may play a role in the progression of the liver disease to hepatocellular carcinoma (HCC). Renal disease is also an important extrahepatic manifestation of hepatitis viral infection and its presence is associated with poor prognosis and management issues. Our study had multiple purposes: to determine the frequency of the association between chronic viral liver disease and diabetes mellitus, evaluate the potential of diabetes mellitus as a risk factor for HCC and assess an eventual renal involvement. We included in our study a number of 246 patients with chronic liver disease, from whom 136 were diagnosed with chronic viral hepatitis and 110 with viral liver cirrhosis. These patients were assessed by using a clinical examination and a series of tests, including serum transaminase levels, serum bilirubin, serum albumin, markers of cholestasis, fasting plasma glucose levels, serum creatinine, urea, albuminuria, Addis-Hamburger test, electrophoresis of urinary proteins, abdominal ultrasound and, in some cases, CT examination. We obtained the following results: diabetes mellitus is often associated with chronic liver disease of viral etiology, having been identified in 18.29% of the patients in our study. Age above 60 in patients with chronic hepatitis (p=0.013diabetes mellitus. Renal disease was present in 13.4% of the patients with chronic liver disease and it was especially associated with liver cirrhosis and hepatitis C virus. The most common form of renal injury was glomerulonephritis. Acute kidney injury was diagnosed only in cirrhotic patients as hepatorenal syndrome, occurring in 7.27% of the subjects, while chronic kidney disease was identified only in two cases of chronic viral hepatitis. Four patients in our study were diagnosed with HCC and none of them presented diabetes mellitus. Our study revealed that there is a

Full Text Available Introduction. There is no published data regarding prevalence of obstructive airway diseases in Iran. We have investigated the prevalence of respiratory symptoms in Shahre-kord to be compared with those in Europe and USA. Methods. Two thousands subjects (977 male and 1016 female were selected by proportional random cluster sampling from Shahre-kord residents aged 1 to 87 years. They were interviewed to complete a respiratory questionnaire and those who were suspected to have airways disorders were invited for physical examinations and spirometry. Findings. The most frequently reported symptoms were: chronic cough (7/4 percent, wheeze ever in life time (5/5 percent, morning cough (6 percent, history of chronic bronchitis (1/8 percent, dyspnea associated with wheeze (3/2 percent, exertional dyspnea (2/9 percent. Cigarette smoking was less popular in our group than the Europ-American populations. Conclusion. Obstructive pulmonary disease are less prevalent in Shahre-kord than those reported in Europe and USA. This finding may be due to smoking habits and less polluted air in Shahre-kord.

Inhaled Antibiotic Therapy in Chronic Respiratory Diseases

Full Text Available The management of patients with chronic respiratory diseases affected by difficult to treat infections has become a challenge in clinical practice. Conditions such as cystic fibrosis (CF and non-CF bronchiectasis require extensive treatment strategies to deal with multidrug resistant pathogens that include Pseudomonas aeruginosa, Methicillin-resistant Staphylococcus aureus, Burkholderia species and non-tuberculous Mycobacteria (NTM. These challenges prompted scientists to deliver antimicrobial agents through the pulmonary system by using inhaled, aerosolized or nebulized antibiotics. Subsequent research advances focused on the development of antibiotic agents able to achieve high tissue concentrations capable of reducing the bacterial load of difficult-to-treat organisms in hosts with chronic respiratory conditions. In this review, we focus on the evidence regarding the use of antibiotic therapies administered through the respiratory system via inhalation, nebulization or aerosolization, specifically in patients with chronic respiratory diseases that include CF, non-CF bronchiectasis and NTM. However, further research is required to address the potential benefits, mechanisms of action and applications of inhaled antibiotics for the management of difficult-to-treat infections in patients with chronic respiratory diseases.

Chronic diseases can be prevented and controlled using available knowledge. Moreover, the solutions are not only effective but can be highly cost-effective. Chronic care model and disease management have emerged, in the last decades, as new models of care delivery. The two models share the objective of improving the quality of care for people with chronic diseases while optimizing health care expenditure. In Italy, within the National Prevention Plan, the Italian Centre for Disease Prevention and Control of the Ministry of Health, and the Istituto Superiore di Sanità (ISS) are developing the IGEA project, which defines a comprehensive strategy for implementing a chronic disease management intervention for people with diabetes.

The risk of chronic obstructive pulmonary disease (COPD), as well as thyroid diseases increases with age. COPD is a common systemic disease associated with chronic inflammation. Many endocrinological disorders, including thyroid gland diseases are related to systemic inflammation. Epidemiological studies suggest that patients with COPD are at higher risk of thyroid disorders. These associations are not well-studied and thyroid gland diseases are not included on the broadly acknowledged list of COPD comorbidities. They may seriously handicap quality of life of COPD patients. Unfortunately, the diagnosis may be difficult, as many signs are masked by the symptoms of the index disease. The comprehension of the correlation between thyroid gland disorders and COPD may contribute to better care of patients. In this review, we attempt to revise available literature describing existing links between COPD and thyroid diseases.

While transradial approach to conduct percutaneous coronary interventions offers multiple advantages, the procedure can cause radial artery damage and occlusion. Because radial artery is the preferred site for the creation of an arteriovenous fistula to provide dialysis, patients with chronic kidney disease are particularly dependent on radial artery for their long-term survival. In this retrospective study, we investigated the prevalence of chronic kidney disease in patients undergoing coronary interventions via radial artery. Stage of chronic kidney disease was based on estimated glomerular filtration rate and National Kidney Foundation - Kidney Disease Outcomes Quality Initiative guidelines. A total of 497 patients undergoing transradial percutaneous coronary interventions were included. Over 70.4% (350/497) of the patients had chronic kidney disease. Stage II chronic kidney disease was observed in 243 (69%) patients (estimated glomerular filtration rate = 76.0 ± 8.4 mL/min). Stage III was observed in 93 (27%) patients (estimated glomerular filtration rate = 49 ± 7.5 mL/min). Stage IV chronic kidney disease was observed in 5 (1%) patients (estimated glomerular filtration rate = 25.6 ± 4.3 mL/min) and Stage V chronic kidney disease was observed in 9 (3%) patients (estimated glomerular filtration rate = 9.3 ± 3.5 mL/min). Overall, 107 of 350 patients (30%) had advanced chronic kidney disease, that is, stage III-V chronic kidney disease. Importantly, 14 of the 107 (13%) patients had either stage IV or V chronic kidney disease. This study finds that nearly one-third of the patients undergoing transradial percutaneous coronary interventions have advanced chronic kidney disease. Because many of these patients may require dialysis, the use of radial artery to conduct percutaneous coronary interventions must be carefully considered in chronic kidney disease population.

The use of radioisotope techniques for the diagnosis of obstructive airway disease

International Nuclear Information System (INIS)

Furudate, Masatsugu; Itoh, Kazuo; Shida, Akira; Minami, Yukisato

1981-01-01

Perfusion scintigraphy, radioaerosol inhalation scintigraphy, 133 Xe studies and sup(81m)Kr studies are useful radioisotope techniques for the detection of regional pulmonary abnormalities in obstructive airway disease. The patient during asthmatic attack shows the perfusion defects with indefinite boundary, which may change during the following several days. Decreased ventilation are seen on the regions with perfusion defects, and ventilatory defects are more marked than those of perfusion. On the other hand, these abnomal findings is reversible. In chronic emphysema or chronic bronchitis, the regions with decreased perfusion usually cannot be correlated with any specific segments, and scintigraphys done repeatedly fail to show re-vascularization on the regions. In the radioaerosol inhalation scintigraphy, deposition pattern reveal the severity of COPD. In addition, xenon studies in the diseases show marked or moderate prolongation of wash-out from the abnormal region, and the abnormalities of ventilation are equal to or exceed the abnormalities of perfusion.

Of the patients with chronic obstructive pulmonary disease (COLD) and severe obstructive syndrome, 39 whose age was under 40 were selected. In 23 of them, the anamnesis revealed bronchopulmonary affections in childhood, that required admission into the hospital (19 were non-smokers). Of the rest of 16 patients, 14 were hard smokers that started to smoke before the age of 14. The functional picture was severely modified, similarly to that of the COLD patients in the 6th decade of life. This suggests that the degradation process started in the childhood, and that the chronic respiratory diseases and/or smoking at an early age had an important role.

Chronic fluorosis: The disease and its anaesthetic implications

Directory of Open Access Journals (Sweden)

Madhuri S Kurdi

2016-01-01

Full Text Available Chronic fluorosis is a widespread disease-related to the ingestion of high levels of fluoride through water and food. Prolonged ingestion of fluoride adversely affects the teeth, bones and other organs and alters their anatomy and physiology. Fluoride excess is a risk factor in cardiovascular disease and other major diseases, including hypothyroidism, diabetes and obesity. Although anaesthesiologists may be aware of its skeletal and dental manifestations, other systemic manifestations, some of which may impact anaesthetic management are relatively unknown. Keeping this in mind, the topic of chronic fluorosis was hand searched from textbooks, scientific journals and electronically through Google, PubMed and other scientific databases. This article concentrates on the effect of chronic fluorosis on various organ systems, its clinical features, diagnosis and the anaesthetic implications of the disease.

2012-12-01

Lifestyle changes, including unhealthy eating habits and high rates of physical inactivity and stress, along with an increase in life expectancy have been accompanied by increasing rates of chronic non-communicable diseases. Chronic diseases are the main causes of death and disability in Brazil. Chronic disease management is one of the most important challenges facing health managers who are constantly seeking interventions and strategies to reduce costs and hospital admissions and to prevent other conditions. However, most existing models of health care have focused exclusively on disease, but it is a mistaken approach. An integrated approach is required to effectively meet patient needs. The purpose of this article was to further discuss policies and strategies for the development of new models of care for the elderly with an emphasis on prevention and resolution actions.

Calcium Balance in Chronic Kidney Disease.

Science.gov (United States)

Hill Gallant, Kathleen M; Spiegel, David M

2017-06-01

The kidneys play a critical role in the balance between the internal milieu and external environment. Kidney failure is known to disrupt a number of homeostatic mechanisms that control serum calcium and normal bone metabolism. However, our understanding of calcium balance throughout the stages of chronic kidney disease is limited and the concept of balance itself, especially with a cation as complex as calcium, is often misunderstood. Both negative and positive calcium balance have important implications in patients with chronic kidney disease, where negative balance may increase risk of osteoporosis and fracture and positive balance may increase risk of vascular calcification and cardiovascular events. Here, we examine the state of current knowledge about calcium balance in adults throughout the stages of chronic kidney disease and discuss recommendations for clinical strategies to maintain balance as well as future research needs in this area. Recent calcium balance studies in adult patients with chronic kidney disease show that neutral calcium balance is achieved with calcium intake near the recommended daily allowance. Increases in calcium through diet or supplements cause high positive calcium balance, which may put patients at risk for vascular calcification. However, heterogeneity in calcium balance exists among these patients. Given the available calcium balance data in this population, it appears clinically prudent to aim for recommended calcium intakes around 1000 mg/day to achieve neutral calcium balance and avoid adverse effects of either negative or positive calcium balance. Assessment of patients' dietary calcium intake could further equip clinicians to make individualized recommendations for meeting recommended intakes.

2018-01-01

Although previous studies have reported that the prevalence of low back pain in Parkinson's disease was over 50% and low back pain was often classified as chronic, risk factors of chronic low back pain have not been previously investigated. The aim of this study was to determine the predictive risk factors of chronic low back pain in Parkinson's disease. One hundred and sixty-eight patients with Parkinson's disease and 179 controls were consecutively included in the study. Demographic data of the two groups and disease characteristics of Parkinson's disease patient group were recorded. Low back pain lasting for ≥3 months was evaluated as chronic. Firstly, the bivariate correlations were calculated between chronic low back pain and all possible risk factors. Then, a multivariate regression was used to evaluate the impact of the predictors of chronic low back pain. The frequency of chronic low back pain in Parkinson's disease patients and controls were 48.2% and 26.7%, respectively (p chronic low back pain in Parkinson's disease were general factors including age (odds ratio = 1.053, p = 0.032) and Hospital Anxiety and Depression Scale - Depression subscore (odds ratio = 1.218, p = 0.001), and Parkinson's disease-related factors including rigidity (odds ratio = 5.109, p = 0.002) and posture item scores (odds ratio = 5.019, p = 0.0001). The chronic low back pain affects approximately half of the patients with Parkinson's disease. Prevention of depression or treatment recommendations for managing depression, close monitoring of anti- parkinsonian medication to keep motor symptoms under control, and attempts to prevent, correct or reduce abnormal posture may help reduce the frequency of chronic low back pain in Parkinson's disease.

Cardiovascular disease constitutes the major cause of mortality in patients with chronic kidney disease. Arterial stiffness is an important contributor to the occurrence and progression of cardiovascular disease. Various risk factors, including altered hormone levels, have been suggested to be associated with arterial stiffness. Based on the background that chronic kidney disease predisposes individuals to a wide range of hormonal changes, we herein review the available data on the association between arterial stiffness and hormones in patients with chronic kidney disease and summarize the data for the general population.

to identify the association between the exposure of workers to inorganic dust in a quarry and a cement factory and pulmonary diseases. a transverse study on data from 32 quarry workers (QWs) and 57 cement production line workers (CFWs) to inorganic-dust exposure was performed. Pulmonary function tests and chest X ray were done in both groups. there were differences between QWs and the CFWs; QWs were younger, shorter and thinner. The number of sick individuals might be considered significantly different, showing a smaller proportion on the cement production line. The quarry workers have been on the company for a shorter period of time and, in the end, they present more serious pulmonary problems with an average of 3 years working. the amount of free-silica that is managed on the quarry affects the workers in some way, even when literature states that the evolution of industrial bronchitis and silicosis have a period development of approximately 10 years.

The aim of this study was to evaluate the effect of chronic disease(s) on work productivity. Using the Health & Work Performance Questionnaire, information was collected from 516 workers on chronic disease status and work productivity. Propensity-score matching was performed to identify matched-pairs of workers. In the propensity-score matched sample, workers with chronic diseases were more likely to have increased absenteeism and presenteeism rates, 6.34 and 2.36 times the rates if no chronic diseases, respectively. In addition, they had greater odds for getting negative critical work incidents and less odds for positive incidents than none or balanced status. Multimorbidity showed more significant increase in absenteeism and presenteeism rates, as well as increased odds for excess negative critical work incidents. Chronic disease(s) can significantly reduce work productivity by increasing absenteeism, presenteeism, and net negative critical incidents.

By November 2013, a total of 125 clinical practice guidelines (CPGs) have been developed in Korea. However, despite the high burden of diseases and the clinical importance of CPGs, most chronic diseases do not have available CPGs. Merely 83 CPGs are related to chronic diseases, and only 40 guidelines had been developed in the last 5 yr. Considering the rate of the production of new evidence in medicine and the worsening burden from chronic diseases, the need for developing CPGs for more chronic diseases is becoming increasingly pressing. Since 2011, the Korean Academy of Medical Sciences and the Korea Centers for Disease Control and Prevention have been jointly developing CPGs for chronic diseases. However, priorities have to be set and resources need to be allocated within the constraint of a limited funding. This study identifies the chronic diseases that should be prioritized for the development of CPGs in Korea. Through an objective assessment by using the analytic hierarchy process and a subjective assessment with a survey of expert opinion, high priorities were placed on ischemic heart disease, cerebrovascular diseases, Alzheimer's disease and other dementias, osteoarthritis, neck pain, chronic kidney disease, and cirrhosis of the liver.

A Mouse Model of Chronic West Nile Virus Disease.

Directory of Open Access Journals (Sweden)

Jessica B Graham

2016-11-01

Full Text Available Infection with West Nile virus (WNV leads to a range of disease outcomes, including chronic infection, though lack of a robust mouse model of chronic WNV infection has precluded identification of the immune events contributing to persistent infection. Using the Collaborative Cross, a population of recombinant inbred mouse strains with high levels of standing genetic variation, we have identified a mouse model of persistent WNV disease, with persistence of viral loads within the brain. Compared to lines exhibiting no disease or marked disease, the F1 cross CC(032x013F1 displays a strong immunoregulatory signature upon infection that correlates with restraint of the WNV-directed cytolytic response. We hypothesize that this regulatory T cell response sufficiently restrains the immune response such that a chronic infection can be maintained in the CNS. Use of this new mouse model of chronic neuroinvasive virus will be critical in developing improved strategies to prevent prolonged disease in humans.

2016-01-01

Chronic inflammatory diseases are the most important causes of mortality in the world today and are on the rise. We now know that immune-driven inflammation is critical in the etiology of these diseases, though the environmental triggers and cellular mechanisms that lead to their development are still mysterious. Many chronic inflammatory diseases are associated with significant shifts in the microbiota towards inflammatory configurations, which can affect the host both by inducing local and systemic inflammation and by alterations in microbiota-derived metabolites. This review discusses recent findings suggesting that shifts in the microbiota may contribute to chronic disease via effects on the immune system. PMID:27623245

Contraception for adolescents with chronic rheumatic diseases

Directory of Open Access Journals (Sweden)

Benito Lourenço

Full Text Available ABSTRACT Contraception is an important issue and should be a matter of concern in every medical visit of adolescent and young patients with chronic rheumatic diseases. This narrative review discusses contraception methods in adolescents with juvenile systemic lupus erythematosus (JSLE, antiphospholipid syndrome (APS, juvenile idiopathic arthritis (JIA and juvenile dermatomyositis (JDM. Barrier methods are safe and their use should be encouraged for all adolescents with chronic rheumatic diseases. Combined oral contraceptives (COC are strictly prohibited for JSLE and APS patients with positive antiphospholipid antibodies. Reversible long-acting contraception can be encouraged and offered routinely to the JSLE adolescent patient and other rheumatic diseases. Progestin-only pills are safe in the majority of rheumatic diseases, although the main concern related to its use by adolescents is poor adherence due to menstrual irregularity. Depot medroxyprogesterone acetate injections every three months is a highly effective contraception strategy, although its long-term use is associated with decreased bone mineral density. COC or other combined hormonal contraceptive may be options for JIA and JDM patients. Oral levonorgestrel should be considered as an emergency contraception method for all adolescents with chronic rheumatic diseases, including patients with contraindication to COC.

Nutrition and prevention of chronic diseases: a unifying eco-nutritional strategy.

Science.gov (United States)

Wahlqvist, M L

2004-02-01

Increasing efforts are being made to address, in public health policy (PHP), both the persistence of nutritional deprivation in economically disadvantaged communities, and the increase in so-called "chronic disease" (abdominal obesity, diabetes, cardiovascular disease, certain cancers, osteoporosis, arthritides, and inflammatory disease) in communities at all stages of economic development. The problems in the "chronic disease" descriptor are that its origins may be as early as conception, rather than during the postnatal lifespan, or even in previous generations; it may appear abruptly or slowly; and it may be amenable to environmental and behavioural intervention well into its course and in older age groups. It is also not necessarily "non-communicable", a qualifier often used for "chronic disease" (chronic non-communicable disease or CNCD) and often has inflammatory features, for example the inflammatory marker C-reactive protein is a predictor of macrovascular disease and ischaemic events can, in part, be prevented in the affected by influenzal vaccination. The nexus between immunodeficiency, inflammatory processes and nutritional status which is characteristic of "infective" and food-borne illness, is also more and more evident in "chronic disease". It may be more helpful to consider "chronic disease" as "eco-disease" with its environmental and behavioural contributors, and to regard that which is clearly nutritionally dependent as "eco-nutritional disease".

The aim of the study was to improve the tactics of treatment of bronchoobstructive syndrome (BOS) in associative course with gastroesophageal reflux disease (GERD) in children. 180 children aged 6-16 with diseases of the respiratory organs with BOS and GERD symptoms were examined: 85 of them--with bronchial asthma (BA), 34--with an acute course of pneumonia, 29--with recurrent obstructive bronchitis. Comparison groups were composed of 93 children, the number of practically healthy children (the control group) was 28 persons. The analysis of risk factors of associative pathology development, roentgenographic study, investigation of the function of external respiration (FER) (peak flowmetry, spirometry), intracavitary pH-metry, esophagofibrogastroduodenoscopy (EFGDS) and ultrasonic investigation (USI) of the organs of the gastro-intestinal tract (GIT) were carried out. Diseases of the respiratory organs with BOS in the groups of the patients under investigation in 43.9% of cases on an average associated with GERD. In a severe course of bronchial asthma GERD was detected 3,4 times more frequently in the boys, while in a lengthy course of pneumonia with BOS--1,9 times more frequently in the girls. Chronic gastritis (ChG) and chronic gastroduodenitis (ChGD) in BA were revealed in 40.6% of the patients, in pneumonia--in 45.7%, in recurrent bronchitis--in 33.3% of the patients. Peculiarities of pre-morbid background of BA and GERD associative course were exhibited by gestosis, threat of abortion, intrauterine hypoxia of the fetus, social troubles of the family. Manifestations of BA in children in 36% of cases were observed 6-12 months after the onset of GERD. The designed individual anti-reflux programs in complex therapy of respiratory organs' diseases with BOS associated with GERD reduce the frequency of exacerbations and hospitalizations of patients with BA, improve their life quality.

Occupational exposure to pesticides and respiratory health

2015-06-01

Full Text Available This article aims to review the available literature regarding the link between occupational exposure to pesticides and respiratory symptoms or diseases. Identification of epidemiological studies was performed using PubMed. 41 articles were included, 36 regarding agricultural workers and five regarding industry workers. Among the 15 cross-sectional studies focusing on respiratory symptoms and agricultural pesticide exposure, 12 found significant associations with chronic cough, wheeze, dyspnoea, breathlessness or chest tightness. All four studies on asthma found a relationship with occupational exposure, as did all three studies on chronic bronchitis. The four studies that performed spirometry reported impaired respiratory function linked to pesticide exposure, suggestive of either obstructive or restrictive syndrome according to the chemical class of pesticide. 12 papers reported results from cohort studies. Three out of nine found a significant relationship with increased risk of wheeze, five out of nine with asthma and three out of three with chronic bronchitis. In workers employed in pesticide production, elevated risks of chronic obstructive pulmonary disease (two studies out of three and impaired respiratory function suggestive of an obstructive syndrome (two studies out of two were reported. In conclusion, this article suggests that occupational exposure to pesticides is associated with an increased risk of respiratory symptoms, asthma and chronic bronchitis, but the causal relationship is still under debate.

Functional genomics in renal transplantation and chronic kidney disease

International Nuclear Information System (INIS)

Wilflingseder, J.

2010-01-01

For the past decade, the development of genomic technology has revolutionized modern biological research. Functional genomic analyses enable biologists to study genetic events on a genome wide scale. Examples of applications are gene discovery, biomarker determination, disease classification, and drug target identification. Global expression profiles performed with microarrays enable a better understanding of molecular signature of human disease, including acute and chronic kidney disease. About 10 % of the population in western industrialized nations suffers from chronic kidney disease (CKD). Treatment of end stage renal disease, the final stage of CKD is performed by either hemo- or peritoneal dialysis or renal transplantation. The preferred treatment is renal transplantation, because of the higher quality of life. But the pathophysiology of the disease on a molecular level is not well enough understood and early biomarkers for acute and chronic kidney disease are missing. In my studies I focused on genomics of allograft biopsies, prevention of delayed graft function after renal transplantation, anemia after renal transplantation, biocompatibility of hemodialysis membranes and peritoneal dialysis fluids and cardiovascular diseases and bone disorders in CKD patients. Gene expression profiles, pathway analysis and protein-protein interaction networks were used to elucidate the underlying pathophysiological mechanism of the disease or phenomena, identifying early biomarkers or predictors of disease state and potentially drug targets. In summery my PhD thesis represents the application of functional genomic analyses in chronic kidney disease and renal transplantation. The results provide a deeper view into the molecular and cellular mechanisms of kidney disease. Nevertheless, future multicenter collaborative studies, meta-analyses of existing data, incorporation of functional genomics into large-scale prospective clinical trials are needed and will give biomedical

Cholesterol Crystal Embolism and Chronic Kidney Disease.

Li, Xuezhu; Bayliss, George; Zhuang, Shougang

2017-05-24

Renal disease caused by cholesterol crystal embolism (CCE) occurs when cholesterol crystals become lodged in small renal arteries after small pieces of atheromatous plaques break off from the aorta or renal arteries and shower the downstream vascular bed. CCE is a multisystemic disease but kidneys are particularly vulnerable to atheroembolic disease, which can cause an acute, subacute, or chronic decline in renal function. This life-threatening disease may be underdiagnosed and overlooked as a cause of chronic kidney disease (CKD) among patients with advanced atherosclerosis. CCE can result from vascular surgery, angiography, or administration of anticoagulants. Atheroembolic renal disease has various clinical features that resemble those found in other kidney disorders and systemic diseases. It is commonly misdiagnosed in clinic, but confirmed by characteristic renal biopsy findings. Therapeutic options are limited, and prognosis is considered to be poor. Expanding knowledge of atheroembolic renal disease due to CCE opens perspectives for recognition, diagnosis, and treatment of this cause of progressive renal insufficiency.

In recent years, Central America, Egypt, India and Sri Lanka have reported a high prevalence of chronic kidney disease of unknown etiology in agricultural communities, predominantly among male farmworkers. This essay examines the disease's case definitions, epidemiology (disease burden, demographics, associated risk factors) and causal hypotheses, by reviewing published findings from El Salvador, Nicaragua, Costa Rica, Sri Lanka, Egypt and India.

Coronavirus-like viruses, designated peafowl/China/LKQ3/2003 (pf/CH/LKQ3/03) and teal/China/LDT3/2003 (tl/CH/LDT3/03), were isolated from a peafowl and a teal during virological surveillance in Guangdong province, China. Partial genomic sequence analysis showed that these isolates had the S-3-M-5-N gene order that is typical of avian coronaviruses. The spike, membrane and nucleocapsid protein genes of pf/CH/LKQ3/03 had >99 % identity to those of the avian infectious bronchitis coronavirus H120 vaccine strain (Massachusetts serotype) and other Massachusetts serotype isolates. Furthermore, when pf/CH/LKQ3/03 was inoculated experimentally into chickens (specific-pathogen-free), no disease signs were apparent. tl/CH/LDT3/03 had a spike protein gene with 95 % identity to that of a Chinese infectious bronchitis virus (IBV) isolate, although more extensive sequencing revealed the possibility that this strain may have undergone recombination. When inoculated into chickens, tl/CH/LDT3/03 resulted in the death of birds from nephritis. Taken together, this information suggests that pf/CH/LKQ3/03 might be a revertant, attenuated vaccine IBV strain, whereas tl/CH/LDT3/03 is a nephropathogenic field IBV strain, generated through recombination. The replication and non-pathogenic nature of IBV in domestic peafowl and teal under field conditions raises questions as to the role of these hosts as carriers of IBV and the potential that they may have to transmit virus to susceptible chicken populations.

Rheumatic heart disease: infectious disease origin, chronic care approach.

Science.gov (United States)

Katzenellenbogen, Judith M; Ralph, Anna P; Wyber, Rosemary; Carapetis, Jonathan R

2017-11-29

Rheumatic heart disease (RHD) is a chronic cardiac condition with an infectious aetiology, causing high disease burden in low-income settings. Affected individuals are young and associated morbidity is high. However, RHD is relatively neglected due to the populations involved and its lower incidence relative to other heart diseases. In this narrative review, we describe how RHD care can be informed by and integrated with models of care developed for priority non-communicable diseases (coronary heart disease), and high-burden communicable diseases (tuberculosis). Examining the four-level prevention model (primordial through tertiary prevention) suggests primordial and primary prevention of RHD can leverage off existing tuberculosis control efforts, given shared risk factors. Successes in coronary heart disease control provide inspiration for similarly bold initiatives for RHD. Further, we illustrate how the Chronic Care Model (CCM), developed for use in non-communicable diseases, offers a relevant framework to approach RHD care. Systems strengthening through greater integration of services can improve RHD programs. Strengthening of systems through integration/linkages with other well-performing and resourced services in conjunction with policies to adopt the CCM framework for the secondary and tertiary prevention of RHD in settings with limited resources, has the potential to significantly reduce the burden of RHD globally. More research is required to provide evidence-based recommendations for policy and service design.

Alcoholic Beverage Consumption and Chronic Diseases

Directory of Open Access Journals (Sweden)

Yue Zhou

2016-05-01

Full Text Available Epidemiological and experimental studies have consistently linked alcoholic beverage consumption with the development of several chronic disorders, such as cancer, cardiovascular diseases, diabetes mellitus and obesity. The impact of drinking is usually dose-dependent, and light to moderate drinking tends to lower risks of certain diseases, while heavy drinking tends to increase the risks. Besides, other factors such as drinking frequency, genetic susceptibility, smoking, diet, and hormone status can modify the association. The amount of ethanol in alcoholic beverages is the determining factor in most cases, and beverage types could also make an influence. This review summarizes recent studies on alcoholic beverage consumption and several chronic diseases, trying to assess the effects of different drinking patterns, beverage types, interaction with other risk factors, and provide mechanistic explanations.

Patients with chronic heart failure (HF) are limited in their quality of life, have a poor prognosis and face frequent hospitalisations. Patient self-management was shown to improve quality of life, reduce rehospitalisations and costs in patients with chronic HF. Comprehensive disease management programmes are critical to foster patient self-management. The chronic care model developed by the WHO serves as the basis of such programmes. In order to develop self-management skills a needs orientated training concept is mandatory, as patients need both knowledge of the illness and the ability to use the information to make appropriate decisions according to their individual situation. Switzerland has no established system for the care of patients with chronic diseases in particular those with HF. For this reason a group of Swiss experts for HF designed a model for disease management for HF patients in Switzerland. Since 2009 the Swiss Heart Foundation offers an education programme based on this model. The aim of this programme is to offer education and support for practitioners, patients and families. An initial pilot evaluation of the program showed mixed acceptance by practitioners, whereas patient assessed the program as supportive and in line with their requirements.

Interrelationship of canonical and non-canonical Wnt signalling pathways in chronic metabolic diseases.

Science.gov (United States)

Ackers, Ian; Malgor, Ramiro

2018-01-01

Chronic diseases account for approximately 45% of all deaths in developed countries and are particularly prevalent in countries with the most sophisticated and robust public health systems. Chronic metabolic diseases, specifically lifestyle-related diseases pertaining to diet and exercise, continue to be difficult to treat clinically. The most prevalent of these chronic metabolic diseases include obesity, diabetes, non-alcoholic fatty liver disease, chronic kidney disease and cardiovascular disease and will be the focus of this review. Wnt proteins are highly conserved glycoproteins best known for their role in development and homeostasis of tissues. Given the importance of Wnt signalling in homeostasis, aberrant Wnt signalling likely regulates metabolic processes and may contribute to the development of chronic metabolic diseases. Expression of Wnt proteins and dysfunctional Wnt signalling has been reported in multiple chronic diseases. It is interesting to speculate about an interrelationship between the Wnt signalling pathways as a potential pathological mechanism in chronic metabolic diseases. The aim of this review is to summarize reported findings on the contrasting roles of Wnt signalling in lifestyle-related chronic metabolic diseases; specifically, the contribution of Wnt signalling to lipid accumulation, fibrosis and chronic low-grade inflammation.

Central Blood Pressure and Chronic Kidney Disease Progression

Directory of Open Access Journals (Sweden)

Debbie L. Cohen

2011-01-01

Full Text Available Hypertension, diabetes, and proteinuria are well-recognized risk factors for progressive kidney function loss. However, despite excellent antihypertensive and antidiabetic drug therapies, which also often lower urinary protein excretion, there remains a significant reservoir of patients with chronic kidney disease who are at high risk for progression to end-stage kidney disease. This has led to the search for less traditional cardiovascular risk factors that will help stratify patients at risk for more rapid kidney disease progression. Among these are noninvasive estimates of vascular structure and function. Arterial stiffness, manifested by the pulse wave velocity in the aorta, has been established in a number of studies as a significant risk factor for kidney disease progression and cardiovascular endpoints. Much less well studied in chronic kidney disease are measures of central arterial pressures. In this paper we cover the physiology behind the generation of the central pulse wave contour and the studies available using these approaches and conclude with some speculations on the rationale for why measurements of central pressure may be informative for the study of chronic kidney disease progression.

Pregnancy across the spectrum of chronic kidney disease.

Hladunewich, Michelle A; Melamad, Nir; Bramham, Kate

2016-05-01

Management of the pregnant woman with chronic kidney disease is difficult for both nephrologists and obstetricians. Prepregnancy counselling with respect to risk stratification, optimization of maternal health prior to pregnancy, as well as management of the many potential pregnancy-associated complications in this complex patient population remains challenging due to the paucity of large, well-designed clinical studies. Furthermore, the heterogeneity of disease and the relative infrequency of pregnancy, particularly in more advanced stages of chronic kidney disease, leaves many clinicians feeling ill prepared to manage these pregnancies. As such, counselling is imprecise and management varies substantially across centers. All pregnancies in women with chronic kidney disease can benefit from a collaborative multidisciplinary approach with a team that consists of nephrologists experienced in the management of kidney disease in pregnancy, maternal-fetal medicine specialists, high-risk pregnancy nursing staff, dieticians, and pharmacists. Further access to skilled neonatologists and neonatal intensive care unit support is essential given the risks for preterm delivery in this patient population. The goal of this paper is to highlight some of the data that currently exist in the literature, provide management strategies for the practicing nephrologist at all stages of chronic kidney disease, and explore some of the knowledge gaps where future multinational collaborative research efforts should concentrate to improve pregnancy outcomes in women with kidney disease across the globe.

The awareness, treatment and prevention of chronic diseases are generally poor among the elderly population of China, whereas the prevention and control of chronic diseases in elderly veteran communities have been ongoing for more than 30 years. Therefore, investigating the awareness status of chronic disabling neurological diseases (CDND) and common chronic diseases (CCD) among elderly veterans may provide references for related programs among the elderly in the general population. A cross-sectional survey was conducted among veterans ≥60 years old in veteran communities in Beijing. The awareness of preventive strategies against dementia, Alzheimer's disease (AD), Parkinson's disease (PD), sleep disorders, cerebrovascular disease (CVD) and CCD such as hypertension, and the approaches used to access this information, including media, word of mouth (verbal communication among the elderly) and health care professionals, were investigated via face-to-face interviews. The awareness rates for CCD and CVD were approximately 100%, but that for AD was the lowest at word-of-mouth peer education.

Ageing populations and unhealthy lifestyles have led to some chronic conditions such as diabetes and heart disease reaching epidemic proportions in many developed nations. This paper explores the potential of mobile technologies to improve this situation. The pervasive nature of these technologies can contribute holistically across the whole spectrum of chronic care ranging from public information access and awareness, through monitoring and treatment of chronic disease, to support for patient carers. A related study to determine the perceptions of healthcare providers to m-health confirmed the view that attitudes were likely to be more important barriers to progress than technology. A key finding concerned the importance of seamless and integrated m-health processes across the spectrum of chronic disease management.

These indicators also allow the burden of illness to be compared across different diseases. Although Lyme disease has recently been acknowledged as a major health threat in the USA with more than 300,000 new cases per year, no comprehensive assessment of the health burden of this tickborne disease is available. This study assesses the HRQoL of patients with chronic Lyme disease (CLD and compares the severity of CLD to other chronic conditions.Methods. Of 5,357 subjects who responded to an online survey, 3,090 were selected for the study. Respondents were characterized as having CLD if they were clinically diagnosed with Lyme disease and had persisting symptoms lasting more than 6 months following antibiotic treatment. HRQoL of CLD patients was assessed using the CDC 9-item metric. The HRQoL analysis for CLD was compared to published analyses for the general population and other chronic illnesses using standard statistical methods.Results. Compared to the general population and patients with other chronic diseases reviewed here, patients with CLD reported significantly lower health quality status, more bad mental and physical health days, a significant symptom disease burden, and greater activity limitations.

Avian infectious bronchitis caused by the infectious bronchitis virus (IBV), and mycoplasmosis caused by Mycoplasma gallisepticum (MG) are two major respiratory diseases in chickens that have resulted in severe economic losses in the poultry industry. We constructed a recombinant adenovirus that simultaneously expresses the S1 spike glycoprotein of IBV and the TM-1 protein of MG (pBH-S1-TM-1-EGFP). For comparison, we constructed two recombinant adenoviruses (pBH-S1-EGFP and pBH-TM-1-EGFP) that express either the S1 spike glycoprotein or the TM-1 protein alone. The protective efficacy of these three vaccine constructs against challenge with IBV and/or MG was evaluated in specific pathogen free chickens. Groups of seven-day-old specific pathogen free chicks were immunized twice, two weeks apart, via the oculonasal route with the pBH-S1-TM-1-EGFP, pBH-S1-EGFP, or pBH-TM-1-EGFP vaccine candidates or the commercial attenuated infectious bronchitis vaccine strain H52 and MG vaccine strain F-36 (positive controls), and challenged with virulent IBV or MG two weeks later. Interestingly, by days 7 and 14 after the booster immunization, pBH-S1-TM-1-EGFP-induced antibody titre was significantly higher (P attenuated commercial IBV vaccine; however, there was no significant difference between the pBH-S1-TM-1-EGFP and attenuated commercial MG vaccine groups (P > 0.05). The clinical signs, the gross, and histopathological lesions scores of the adenovirus vaccine constructs were not significantly different from that of the attenuated commercial IBV or MG vaccines (positive controls) (P > 0.05). These results demonstrate the potential of the bivalent pBH-S1-TM-1-EGFP adenovirus construct as a combination vaccine against IB and mycoplasmosis.

Autoantibodies in Chronic Obstructive Pulmonary Disease

Directory of Open Access Journals (Sweden)

2018-01-01

Full Text Available Chronic obstructive pulmonary disease (COPD, the fourth leading cause of death worldwide, is characterized by irreversible airflow limitation based on obstructive bronchiolitis, emphysema, and chronic pulmonary inflammation. Inhaled toxic gases and particles, e.g., cigarette smoke, are major etiologic factors for COPD, while the pathogenesis of the disease is only partially understood. Over the past decade, an increasing body of evidence has been accumulated for a link between COPD and autoimmunity. Studies with clinical samples have demonstrated that autoantibodies are present in sera of COPD patients and some of these antibodies correlate with specific disease phenotypes. Furthermore, evidence from animal models of COPD has shown that autoimmunity against pulmonary antigens occur during disease development and is capable of mediating COPD-like symptoms. The idea that autoimmunity could contribute to the development of COPD provides a new angle to understand the pathogenesis of the disease. In this review article, we provide an advanced overview in this field and critically discuss the role of autoantibodies in the pathogenesis of COPD.

Chronic diseases are major killers in the modern era. Physical inactivity is a primary cause of most chronic diseases. The initial third of the article considers: activity and prevention definitions; historical evidence showing physical inactivity is detrimental to health and normal organ functional capacities; cause vs. treatment; physical activity and inactivity mechanisms differ; gene-environment interaction [including aerobic training adaptations, personalized medicine, and co-twin physical activity]; and specificity of adaptations to type of training. Next, physical activity/exercise is examined as primary prevention against 35 chronic conditions [Accelerated biological aging/premature death, low cardiorespiratory fitness (VO2max), sarcopenia, metabolic syndrome, obesity, insulin resistance, prediabetes, type 2 diabetes, non-alcoholic fatty liver disease, coronary heart disease, peripheral artery disease, hypertension, stroke, congestive heart failure, endothelial dysfunction, arterial dyslipidemia, hemostasis, deep vein thrombosis, cognitive dysfunction, depression and anxiety, osteoporosis, osteoarthritis, balance, bone fracture/falls, rheumatoid arthritis, colon cancer, breast cancer, endometrial cancer, gestational diabetes, preeclampsia, polycystic ovary syndrome, erectile dysfunction, pain, diverticulitis, constipation, and gallbladder diseases]. The article ends with consideration of deterioration of risk factors in longer-term sedentary groups; clinical consequences of inactive childhood/adolescence; and public policy. In summary, the body rapidly maladapts to insufficient physical activity, and if continued, results in substantial decreases in both total and quality years of life. Taken together, conclusive evidence exists that physical inactivity is one important cause of most chronic diseases. In addition, physical activity primarily prevents, or delays, chronic diseases, implying that chronic disease need not be an inevitable outcome during life

The dramatic increase in smartphone usage has spurred the development of many health-related mobile applications (apps). On the other hand, population aging and the associated rise in the incidence of chronic disease is increasing the demand for long-term care. Effective chronic disease self-management has been shown to help patients improve their health condition. Numerous smartphone applications currently support patient self-management of chronic disease, facilitating health management and health promotion. The purpose of the present article was to introduce the definition, contents, and types of health-related apps; to discuss the effectiveness of self-management health-related apps in promoting chronic disease management; and to assess and evaluate these apps. We hope that the present article helps give to healthcare professionals and patients who are willing to manage their diseases a general understanding of health-related apps and their potential to facilitate the self-management of chronic diseases.

Sarcopenia and frailty in chronic respiratory disease

Bone, Anna E; Hepgul, Nilay; Kon, Samantha

2017-01-01

Sarcopenia and frailty are geriatric syndromes characterized by multisystem decline, which are related to and reflected by markers of skeletal muscle dysfunction. In older people, sarcopenia and frailty have been used for risk stratification, to predict adverse outcomes and to prompt intervention aimed at preventing decline in those at greatest risk. In this review, we examine sarcopenia and frailty in the context of chronic respiratory disease, providing an overview of the common assessments tools and studies to date in the field. We contrast assessments of sarcopenia, which consider muscle mass and function, with assessments of frailty, which often additionally consider social, cognitive and psychological domains. Frailty is emerging as an important syndrome in respiratory disease, being strongly associated with poor outcome. We also unpick the relationship between sarcopenia, frailty and skeletal muscle dysfunction in chronic respiratory disease and reveal these as interlinked but distinct clinical phenotypes. Suggested areas for future work include the application of sarcopenia and frailty models to restrictive diseases and population-based samples, prospective prognostic assessments of sarcopenia and frailty in relation to common multidimensional indices, plus the investigation of exercise, nutritional and pharmacological strategies to prevent or treat sarcopenia and frailty in chronic respiratory disease.

STRESS AS PREDISPOSING FACTOR OF SOME CHRONIC DISEASES INCLUDING PERIODONTAL DISEASE

Dewi-Nurul M Dewi-Nurul

2006-04-01

Full Text Available Stress is hypothesized as a common pathway for several related chronic diseases of man. Psychosocial stress as modified by perceptions and coping by patients can lead to physical processes. Psychoneuroimmunologic (PNI studies have suggested that psychosocial stress can alter immune function and increase vulnerability to illnesses. The patients also have high sensitivity to periodontal disease (PD. This article describes the association of stress as a physiological response to diseases such as PD, rheumatoid arthritis (RA, and inflammatory bowel disease. The psychosocial stress can lead to physiological processes through 1 the hypothalamic-pituitary-adrenal (HPA axis leading to glucocortico-steroid secretion; 2 the autonomic nervous system, resulting in the release of catecholamine; or 3 the hypothalamic-pituitary-gonadal axis, resulting in the release of sex hormones. These processes may affect chronic diseases. It can be concluded that psychosocial stress in periodontal disease patients must be considered and social support must be provided in order to achieve an optimum periodontal therapy result.

Minimal encephalopathy was originally associated with chronic liver disease but is increasingly associated with most other chronic diseases and particularly with diabetes and also chronic disorders in other organs: kidneys, lungs, thyroid and with obesity. It is increasingly with dramatically increased and more or less permanent increase in systemic inflammation, most likely a result of Western lifestyle. Frequent physical exercise and intake of foods rich in vitamins, antioxidants, fibres, lactic acid bacteria etc in combination with reduction in intake of refined and processed foods is known to reduce systemic inflammation and prevent chronic diseases. Some lactic acid bacteria, especially Lb paracasei, lb plantarum and pediococcus pentosaceus have proven effective to reduce inflammation and eliminate encephalopathy. Significant reduction in blood ammonia levels and endotoxin levels were reported in parallel to improvement of liver disease. Subsequent studies with other lactic acid bacteria seem to demonstrate suppression of inflammation and one study also provides evidence of clinical improvement.

Chan, Roxane Raffin; Larson, Janet L

2015-12-01

The rapidly growing body of research regarding the use of meditation interventions in chronic disease presents an opportunity to compare outcomes based on intervention content. For this review, meditation interventions were described as those interventions delivered to persons with chronic disease where sitting meditation was the main or only content of the intervention with or without the addition of mindful movement. This systematic review identified 45 individual research studies that examined meditations effect on levels of anxiety, depression, and chronic disease symptoms in persons with chronic disease. Individual studies were assessed based on interventional content, the consistency with which interventions were applied, and the research quality. This study identified seven categories of meditation interventions based on the meditation skills and mindful movement practices that were included in the intervention. Overall, half of the interventions had clearly defined and specific meditation interventions (25/45) and half of the studies were conducted using randomized control trials (24/45). © The Author(s) 2015.

Vouchers for chronic disease care.

Watts, Jennifer J; Segal, Leonie

This paper explores the economic implications of vouchers for chronic disease management with respect to achieving objectives of equity and efficiency. Vouchers as a payment policy instrument for health care services have a set of properties that suggest they may address both demand-side and supply-side issues, and contribute to equity and efficiency. They provide a means whereby health care services can be targeted at selected groups, enabling consumer choice of provider, and encouraging competition in the supply of health services. This analysis suggests that, when structured appropriately, vouchers can support consumers to choose services that will meet their health care needs and encourage competition among providers. Although they may not be appropriate across the entire health care system, there are features of vouchers that make them a potentially attractive option, especially for the management of chronic disease.

Src family kinases in chronic kidney disease.

Science.gov (United States)

Wang, Jun; Zhuang, Shougang

2017-09-01

Src family kinases (SFKs) belong to nonreceptor protein tyrosine kinases and have been implicated in the regulation of numerous cellular processes, including cell proliferation, differentiation, migration and invasion, and angiogenesis. The role and mechanisms of SFKs in tumorgenesis have been extensively investigated, and some SFK inhibitors are currently under clinical trials for tumor treatment. Recent studies have also demonstrated the importance of SFKs in regulating the development of various fibrosis-related chronic diseases (e.g., idiopathic pulmonary fibrosis, liver fibrosis, renal fibrosis, and systemic sclerosis). In this article, we summarize the roles of SFKs in various chronic kidney diseases, including glomerulonephritis, diabetic nephropathy, human immunodeficiency virus-associated nephropathy, autosomal dominant form of polycystic kidney disease, and obesity-associated kidney disease, and discuss the mechanisms involved.

2012-10-01

To compare chronic physical health disorder prevalence amongst Australian adults with and without mental illness. Total n=1,716 participants (58% female) with a mean age of 52 ± 13 years (range: 18 to 89 years) completed an online survey of Australian adults in 2010. Outcome measures including prevalence of chronic physical conditions and self-reported body mass index (BMI) in n=387 (23%) with a self-reported mental illness diagnosis were compared to respondents without mental illness. A significantly higher proportion of participants with mental illness were obese (BMI ≥ 30; 31 vs 24%, p=0.005). Adjusted odds ratios (OR) for coronary heart disease, diabetes, chronic bronchitis or emphysema, asthma, irritable bowel syndrome, and food allergies or intolerances (OR range: 1.54-3.19) demonstrated that chronic physical disorders were significantly more common in participants with a mental illness. Australian adults with a diagnosis for mental illness have a significantly increased likelihood of demonstrating chronic physical health disorders compared to persons without mental illness. Health professionals must be alert to the increased likelihood of comorbid chronic physical disorders in persons with a mental illness and should consider the adoption of holistic approaches when treating those with either a mental or physical illness. © 2012 The Authors.

Full Text Available A liquid phase blocking ELISA (LPB-ELISA was developed for the detection and measurement of antibodies against infectious bronchitis virus (IBV. The purified and nonpurified virus used as antigen, the capture and detector antibodies, and the chicken hyperimmune sera were prepared and standardized for this purpose. A total of 156 sera from vaccinated and 100 from specific pathogen-free chickens with no recorded contact with the virus were tested. The respective serum titers obtained in the serum neutralization test (SNT were compared with those obtained in the LPB-ELISA. There was a high correlation (r2 = 0.8926 between the two tests. The LPB-ELISA represents a single test suitable for the rapid detection of antibodies against bronchitis virus in chicken sera, with good sensitivity (88%, specificity (100% and agreement (95.31%.

Chronic Lyme disease: misconceptions and challenges for patient management

Halperin JJ

2015-05-01

Full Text Available John J HalperinDepartment of Neurosciences, Overlook Medical Center, Summit, NJ, USAAbstract: Lyme disease, infection with the tick-borne spirochete Borrelia burgdorferi, causes both specific and nonspecific symptoms. In untreated chronic infection, specific manifestations such as a relapsing large-joint oligoarthritis can persist for years, yet subside with appropriate antimicrobial therapy. Nervous system involvement occurs in 10%–15% of untreated patients and typically involves lymphocytic meningitis, cranial neuritis, and/or mononeuritis multiplex; in some rare cases, patients have parenchymal inflammation in the brain or spinal cord. Nervous system infection is similarly highly responsive to antimicrobial therapy, including oral doxycycline. Nonspecific symptoms such as fatigue, perceived cognitive slowing, headache, and others occur in patients with Lyme disease and are indistinguishable from comparable symptoms occurring in innumerable other inflammatory states. There is no evidence that these nonspecific symptoms reflect nervous system infection or damage, or that they are in any way specific to or diagnostic of this or other tick-borne infections. When these symptoms occur in patients with Lyme disease, they typically also subside after antimicrobial treatment, although this may take time. Chronic fatigue states have been reported to occur following any number of infections, including Lyme disease. The mechanism underlying this association is unclear, although there is no evidence in any of these infections that these chronic posttreatment symptoms are attributable to ongoing infection with B. burgdorferi or any other identified organism. Available appropriately controlled studies indicate that additional or prolonged courses of antimicrobial therapy do not benefit patients with a chronic fatigue-like state after appropriately treated Lyme disease. Keywords: Lyme disease, Borrelia burgdorferi, chronic, diagnosis, treatment, chronic

It is clear that inflammation plays an important role in developing chronic lung disease in preterm infants. The purpose of the present study is to investigate changes of serum soluble tumor necrosis factor receptor-1 levels over time in infants with chronic lung disease. The serum levels of soluble tumor necrosis factor receptor-1 were measured after delivery, and at 7, 14, 21 and 28 days of age in 10 infants with chronic lung disease and in 18 infants without chronic lung disease. The serum level of soluble tumor necrosis factor receptor-1 was significantly higher in infants with chronic lung disease than in infants without chronic lung disease after delivery. The differences between these two groups remained up to 28 days of age. Prenatal inflammation with persistence into postnatal inflammation may be involved in the onset of chronic lung disease.

2015-03-01

To demonstrate the health economic impact of OM-85, a bacterial lysates based immunostimulant, for its approved indications in China. A cost-effectiveness decision tree model was constructed comparing OM-85 with the best supportive care/placebo therapy for managing the acute exacerbation of chronic bronchitis and rhinosinusitis in the Chinese population. Clinical efficacy and adverse events (AE) data were included in the model based on a thorough literature review. All localized direct treatment costs, including drug cost, AE costs, and medical treatment costs for underlining diseases were included from a Chinese third party payer perspective. A Key Opinion Leaders (KOL) survey was conducted with 20 senior physicians specialized in respiratory, ENT, allergy, and immunology fields from tertiary hospitals in Beijing, Shanghai, Guangzhou, Hangzhou, Shenyang, and Wuhan to validate the local treatment costs. Incremental cost-effectiveness ratio (ICER) was calculated based on the above efficacy and cost information. OM-85 is a cost-effective therapy when compared with placebo (standard care). OM-85 can treat/prevent one additional full episode exacerbation of chronic bronchitis and one additional full episode exacerbation of rhinosinusitis with only additional costs of RMB 653 and RMB 1182.84, respectively. In comparison, each acute exacerbation of chronic bronchitis will cost RMB 4510.10, and each acute exacerbation of rhinosinuisitis will cost RMB 1807.21 in a Chinese clinical management setting. One-way sensitivity analyses were performed and the ICER result was demonstrated to be consistent. OM 85 reduces acute exacerbations among patients with chronic bronchitis and chronic rhinosinusitis when compared with Placebo (standard care). From a Chinese payer perspective, OM 85 is a cost-effective therapy in the clinical management of both chronic bronchitis and rhinosinusitis in the adult population.

Full Text Available Chronic lung diseases include a variety of obstinate and fatal diseases, including asthma, chronic obstructive pulmonary disease (COPD, cystic fibrosis (CF, idiopathic pulmonary fibrosis (IPF, and lung cancers. Pharmacotherapy is important for the treatment of chronic lung diseases, and current progress in nanoparticles offers great potential as an advanced strategy for drug delivery. Based on their biophysical properties, nanoparticles have shown improved pharmacokinetics of therapeutics and controlled drug delivery, gaining great attention. Herein, we will review the nanoparticle-based drug delivery system for the treatment of chronic lung diseases. Various types of nanoparticles will be introduced, and recent innovative efforts to utilize the nanoparticles as novel drug carriers for the effective treatment of chronic lung diseases will also be discussed.

Objective: To describe the mortality pattern pertaining to chronic liver disease (CLD) in Northern Pakistan. Results: There were a total of 8529 admissions in twelve months period from August 2001 to July 2002. There were 283 (3.31%) total deaths. Out of these, 160 deaths were pertaining to medical causes. Out of these medical cases, 33 (20.6%) patients had died of chronic liver disease. Other major causes of death were cerebro-vascular accident (18.7%), malignancy (18.1%) and acute myocardial infarction (10.6%). Out of 33 patients of CLD, 12 (36%) presented with acute gastrointestinal (Gl) bleeding, 9(27%) presented with Ascites and 6(18%) presented with altered mental status due to hepatic encephalopathy. Rest of them had jaundice and fever as their initial presentation. Out of these 33 patients with CLD, 23 (70%) had hepatitis C virus (HCV) as cause of their liver disease, 4 (12%) had hepatitis B virus (HBV) infection, 3(9%) had both hepatitis B and hepatitis C virus infections and 3 (9%) had no known cause of their chronic liver disease. Conclusion: Chronic liver disease is a major cause of mortality in this part of Pakistan at a tertiary care hospital. HCV infection is the main cause of chronic liver disease followed by either HBV or a combination of these viruses. Major manifestations of CLD have been gastrointestinal bleeding, hepatic failure and portal hypertension.(author)

Cirrhotic patients are known to have abnormally high signal principally in the globus pallidus on non-contrast T1-weighted MRI. The purpose of this study was to relate MR changes to clinical and pathological features of chronic liver disease. We confirmed abnormally high signal in the globus pallidus on T1-weighted images in 25 of 28 patients with chronic liver disease, showing that it also occurs in patients who have not yet progressed to cirrhosis. Changes were seen in patients both with and without clinical portosystemic shunting. This abnormality is not responsible for hepatic encephalopathy. Cholestatic disease was more likely to produce marked changes than non-cholestatic disease. No statistically significant correlation was demonstrated between the severity of liver disease and the degree of MR abnormality. However, marked improvement in MR appearances was seen after successful liver transplantation. (orig.). With 3 figs., 4 tabs.

Absence rates of postmen due to bronchitis was found to be definitely associated with pollution and even more so if the ratio of postmen-postal clerk morbidity is used as an index. Bronchitis morbidity correlated with frequency of heavy fogs but very little with population density or overcrowding. In contrast, infectious diseases showed strong correlation with the latter two but not with fog. Minor infections among younger bronchitics were similar in frequency in all areas but led to more frequent complications and absence from work in older postmen living in polluted areas. Smoking acts synergistically.

Full Text Available Objective. To compare the occurrence of pre-existing and subsequent comorbidity among older cancer patients (≥60 years with older non-cancer patients. Material and Methods. Each cancer patient (n=3835, mean age 72 was matched with four non-cancer patients in terms of age, sex, and practice. The occurrence of chronic diseases was assessed cross-sectionally (lifetime prevalence at time of diagnosis and longitudinally (incidence after diagnosis for all cancer patients and for breast, prostate, and colorectal cancer patients separately. Cancer and non-cancer patients were compared using logistic and Cox regression analysis. Results. The occurrence of the most common pre-existing and incident chronic diseases was largely similar in cancer and non-cancer patients, except for pre-existing COPD (OR 1.21, 95% CI 1.06–1.37 and subsequent venous thrombosis in the first two years after cancer diagnosis (HR 4.20, 95% CI 2.74–6.44, which were significantly more frequent (P<0.01 among older cancer compared to non-cancer patients. Conclusion. The frequency of multimorbidity in older cancer patients is high. However, apart from COPD and venous thrombosis, the incidence of chronic diseases in older cancer patients is similar compared to non-cancer patients of the same age, sex, and practice.

Prevalence of occupational disease

Energy Technology Data Exchange (ETDEWEB)

Newhouse, M.L.

1976-12-01

When discussing the prevalence of occupational disease, both the prescribed diseases and the diseases where occupation has an important etiological component should be considered. Available statistics indicate that there has been a substantial improvement in the control of important prescribed diseases such as lead poisoning and pneumoconiosis. In the United Kingdom in 1900 there were 1000 cases of lead poisoning with 38 fatalities. This number decreased to 49 cases in 1956 when the number again increased due to a change from clinical diagnosis to diagnosis on biochemical evidence. The number of cases of coal workers' pneumoconiosis has declined since the 1950s but the number of coal miners has also been reduced by more than /sup 1///sub 3/. Industrial dermatitis is still a considerable problem. Vibration induced white fingers was mentioned as a disease with a very large occupational component but which for a variety of reasons is not prescribed for industrial injury benefit. Illnesses due to injuries to the back, to sciatica, disc disease or lumbago cause a very large amount of sickness and are often associated with heavy manual labor particularly if an awkward posture has to be adopted for the job. The average absence after a back injury in the London Docks was 61 days. Chronic bronchitis is the biggest single cause of sickness absence. Many studies have shown that the etiology is multifactorial but that hard physical work and a dusty environment in the work place are important adverse factors. Improved control of the working environment and methods of work may influence the development of chronic disease in the older worker.

The primary care areas of priority (PCAP) activity was developed to engage medical students in learning about chronic disease management in a clinical context from their peers. It is one of several summative assessment tasks that occur during a primary care community term rotation in a graduate-entry medical programme. We evaluated the acceptability and effectiveness of the PCAP activity as a combined teaching, learning and assessment innovation. Evaluation and assessment data from students who rotated through the four community term blocks during the 2011-2012 academic year was analysed using both qualitative and quantitative methods. PCAP peer teaching activity is an effective format for teaching about the management of chronic conditions in the community Analysis indicated that 89 per cent (n = 148/166) of responding students rated the PCAP as satisfactory, good or excellent. The marking rubric contained 11 assessable components, including teaching skills, mastery of clinical knowledge, developing a management plan, disease prevention and health promotion opportunities, identifying patient safety issues, the impact of the clinical presentation on the patient and family, and consideration of health equity factors. Analysis of the assessment scores indicated that the majority of students achieved the specified learning outcomes. The PCAP peer teaching activity was an acceptable and effective format for teaching about the management of chronic conditions in the community, and is adaptable to other teaching contexts. Students enjoyed teaching and being taught by their peers, and assessment results indicated that they developed their clinical knowledge as well as their teaching ability regarding chronic disease management. © 2014 John Wiley & Sons Ltd.

Long-term ambient concentrations of total suspended particulates and oxidants as related to incidence of chronic disease in California Seventh-Day Adventists

Cancer incidence and mortality in a cohort of 6000 nonsmoking California Seventh-Day Adventists were monitored for a 6-year period, and relationships with long-term cumulative air pollution were observed. Total suspended particulates (TSP) and ozone were measured in terms of numbers of hours in excess of several threshold levels corresponding to national standards as well as mean concentration. For all malignant neoplasms among females, risk increased with increasing exceedance frequencies of all thresholds of TSP except the lowest one, and those increased risks were highly statistically significant. For respiratory cancers, increased risk was associated with only one threshold of ozone, and this result was of borderline significance. Respiratory disease symptoms were assessed in 1977 and again in 1987 using the National Heart, Lung and Blood Institute respiratory symptoms questionnaire on a subcohort of 3914 individuals. Multivariate analyses which adjusted for past and passive smoking and occupational exposures indicated statistically significantly elevated relative risks ranging up to 1.7 for incidence of asthma, definite symptoms of airway obstructive disease, and chronic bronchitis with TSP in excess of all thresholds except the lowest one but not for any thresholds of ozone. A trend association was noted between the threshold of 10 pphm ozone and incidence of asthma. These results are presented within the context of standards setting for these constituents of air pollution.

Feline aminopeptidase N is not a functional receptor for avian infectious bronchitis virus

Harbison Carole E

2007-02-01

Full Text Available Abstract Background Coronaviruses are an important cause of infectious diseases in humans, including severe acute respiratory syndrome (SARS, and have the continued potential for emergence from animal species. A major factor in the host range of a coronavirus is its receptor utilization on host cells. In many cases, coronavirus-receptor interactions are well understood. However, a notable exception is the receptor utilization by group 3 coronaviruses, including avian infectious bronchitis virus (IBV. Feline aminopeptidase N (fAPN serves as a functional receptor for most group 1 coronaviruses including feline infectious peritonitis virus (FIPV, canine coronavirus, transmissible gastroenteritis virus (TGEV, and human coronavirus 229E (HCoV-229E. A recent report has also suggested a role for fAPN during IBV entry (Miguel B, Pharr GT, Wang C: The role of feline aminopeptidase N as a receptor for infectious bronchitis virus. Brief review. Arch Virol 2002, 147:2047–2056. Results Here we show that, whereas both transient transfection and constitutive expression of fAPN on BHK-21 cells can rescue FIPV and TGEV infection in non-permissive BHK cells, fAPN expression does not rescue infection by the prototype IBV strain Mass41. To account for the previous suggestion that fAPN could serve as an IBV receptor, we show that feline cells can be infected with the prototype strain of IBV (Mass 41, but with low susceptibility compared to primary chick kidney cells. We also show that BHK-21 cells are slightly susceptible to certain IBV strains, including Ark99, Ark_DPI, CA99, and Iowa97 ( Conclusion We conclude that fAPN is not a functional receptor for IBV, the identity of which is currently under investigation.
