    Purpose Gastro-esophageal reflux (GER), particularly non-acid reflux, is common in infants and is a known cause of chronic respiratory symptoms in infancy. Recent guidelines recommended empirical acid suppression therapy and the head-up position in patients with suspected GER. However, the efficacy of the upright position in relieving GER and reflux-related respiratory symptoms in infants is unclear. We conducted this study to investigate the efficacy of the upright position on GER and reflux...

    A possible relationship between Na+ intake and increased prevalence and mortality from asthma and chronic obstructive pulmonary disease (COPD) has been suggested but not clearly proven for several reasons (difficulty in assessing Na+ and K+ both by 24 h excretion and dietary recall, too small an effect of these ions on the pathology, and the role of potential confounders). We wanted to determine the relationship of Na+ and K+ intake, assessed by means of a 7 day recall, with chronic respiratory symptoms and bronchial responsiveness in a sample of the general population. Two hundred and five subjects were studied, with complete dietary and respiratory questionnaires, and baseline respiratory function tests, together with a subsample of 146 subjects who underwent histamine challenge. The 7 day recall consisted of two parts: the first assessed discretionary Na+; and the second assessed Na+ and K+ contained in food. The whole sample was split into two groups based on the levels of consumption, and the statistical analysis was performed contrasting the three lower quartiles vs the highest. Smoking habit, social economic status, age and body mass index (BMI) were not confounders for Na+ and K+ intake. The prevalence of symptomatic subjects and baseline respiratory function values were not significantly different in the two groups of quartiles for Na+ and K+. Baseline respiratory values and dose-response slope of the subsample were also not significantly different. We did not prove a relationship between these dietary factors and either bronchial responsiveness or chronic respiratory symptoms. Although we consider that our questionnaire is more reliable than other methods for Na+ and K+ assessment, several potential biases still remain.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:7613539

  4. Isotopic evaluation of nasal mucociliary transport in patients with chronic respiratory symptoms

    International Nuclear Information System (INIS)

    Introduction: There are a large number of patients with chronic respiratory symptoms especially in pediatric population in whom it would be important to rule out primary ciliary dyskinesia (PCD) by electron microscopic examination of cilia obtained from respiratory mucosal biopsies, an expensive and not widely available procedure. Our purpose was to evaluate the role of the radioisotopic mucociliary transport measurement on selecting patients for nasal or tracheobronchial biopsy. Methods: The velocity of nasal mucociliary transport (VNMT) was measured in 100 patients, aged 2m-39y, mean 9 yo, from feb-1999 until feb-2002. Ten were healthy controls. The others had chronic o recurrent respiratory symptoms. The procedure consisted to place a 99mTc-MAA droplet in one nostril by direct vision and follows its course using a gammacamera-computer system in order to calculate its speed expressed in mm/min. Sedation was needed in the vast majority of children below 4 yo. Values below 3 mm/min were repeated to ensure an accurate result. All cases having VNMT below 2,5 mm/min underwent nasal mucosal biopsy. In some patients with VNMT above 2,5 mm/min, nasal mucosal biopsy was also done based on other considerations. Patients were classified in three groups. Those having respiratory symptoms and no biopsy done (CRRS.NB); patients with respiratory symptoms and PCD diagnosed by biopsy (CRRS.PCD.B (+)); healthy controls. Results: Al cases with CRRS. PCD.B(+) had VNMT below 2.4 mm/min with a mean significantly different from those in CRRS.NB and healthy controls. There were no overlapping between the VNMT highest value in patients having CRRS. PCD.B(+) and the lowest VNMT in CRRS.NB or healthy controls. The results are similar to those published by other centers. Conclusions: The radioisotopic method to measure VNMT is feasible, inexpensive and relatively easy to perform. As PCD has important differences in prognosis and treatment from other conditions with similar symptoms, it is

    Full Text Available Abstract Background Coffee processing causes organic dust exposure which may lead to development of respiratory symptoms. Previous studies have mainly focused on workers involved in roasting coffee in importing countries. This study was carried out to determine total dust exposure and respiratory health of workers in Tanzanian primary coffee-processing factories. Methods A cross sectional study was conducted among 79 workers in two coffee factories, and among 73 control workers in a beverage factory. Personal samples of total dust (n = 45 from the coffee factories and n = 19 from the control factory were collected throughout the working shift from the breathing zone of the workers. A questionnaire with modified questions from the American Thoracic Society questionnaire was used to assess chronic respiratory symptoms. Differences between groups were tested by using independent t-tests and Chi square tests. Poisson Regression Model was used to estimate prevalence ratio, adjusting for age, smoking, presence of previous lung diseases and years worked in dusty factories. Results All participants were male. The coffee workers had a mean age of 40 years and were older than the controls (31 years. Personal total dust exposure in the coffee factories were significantly higher than in the control factory (geometric mean (GM 1.23 mg/m3, geometric standard deviation (GSD (0.8 vs. 0.21(2.4 mg/m3. Coffee workers had significantly higher prevalence than controls for cough with sputum (23% vs. 10%; Prevalence ratio (PR; 2.5, 95% CI 1.0 - 5.9 and chest tightness (27% vs. 13%; PR; 2.4, 95% CI 1.1 - 5.2. The prevalence of morning cough, cough with and without sputum for 4 days or more in a week was also higher among coffee workers than among controls. However, these differences were not statistically significant. Conclusion Workers exposed to coffee dust reported more respiratory symptoms than did the controls. This might relate to their exposure to coffee dust

    Full Text Available Megaesophagus as the end result of achalasia is the consequence of disordered peristalsis and the slow decompensation of the esophageal muscular layer. The main symptoms of achalasia are dysphagia, regurgitation, chest pain and weight loss, but respiratory symptoms, such as coughing, particularly when patients lie in a horizontal position, may also be common due to microaspiration. A 70-year old woman suffered from a nocturnal cough and shortness of breath with stridor. She reported difficulty in swallowing food over the past ten years, but had adapted by eating a semi-liquid diet. Chest X-ray showed right hemithorax patchy opacities projecting from the posterior mediastinum. Chest computed tomography scan showed a marked dilatation of the esophagus with abundant food residues. Endoscopy confirmed the diagnosis of megaesophagus due to esophageal achalasia, excluding other causes of obstruction, such as secondary esophagitis, polyps, leiomyoma or leiomyosarcoma. In the elderly population, swallowing difficulties due to esophageal achalasia are often underestimated and less troublesome than the respiratory symptoms that are caused by microaspiration. The diagnosis of esophageal achalasia, although uncommon, should be considered in patients with nocturnal chronic coughs and shortness of breath with stridor when concomitant swallowing difficulties are present.

    Full Text Available Abstract Background There are only a few follow-up studies of respiratory function among cement workers. The main aims of this study were to measure total dust exposure, to examine chronic respiratory symptoms and changes in lung function among cement factory workers and controls that were followed for one year. Methods The study was conducted in two cement factories in Ethiopia. Totally, 262 personal measurements of total dust among 105 randomly selected workers were performed. Samples of total dust were collected on 37-mm cellulose acetate filters placed in closed faced Millipore-cassettes. Totally 127 workers; 56 cleaners, 44 cement production workers and 27 controls were randomly selected from two factories and examined for lung function and interviewed for chronic respiratory symptoms in 2009. Of these, 91 workers; 38 cement cleaners (mean age 32 years, 33 cement production workers (36 years and 20 controls (38 years were examined with the same measurements in 2010. Results Total geometric mean dust exposure among cleaners was 432 mg/m3. The fraction of samples exceeding the Threshold Limit Value (TLV of 10 mg/m3 for the cleaners varied from 84-97% in the four departments. The levels were considerably lower among the production workers (GM = 8.2 mg/m3, but still 48% exceeded 10 mg/m3. The prevalence of all the chronic respiratory symptoms among both cleaners and production workers was significantly higher than among the controls. Forced Expiratory Volume in one second (FEV1 and FEV1/Forced Vital Capacity (FEV1/FVC were significantly reduced from 2009 to 2010 among the cleaners (p Conclusions The high prevalence of chronic respiratory symptoms and reduction in lung function is probably associated with high cement dust exposure. Preventive measures are needed to reduce the dust exposure.

    Full Text Available OBJECTIVE: Despite the intensive use of pesticides in agriculture there are few studies assessing the risk of respiratory conditions from this exposure. The study aimed at quantifying the prevalence of respiratory symptoms among farmers and evaluating its relationship with occupational use of pesticides and the prevalence of respiratory symptoms. METHODS: A cross-sectional study was conducted among 1,379 farmers from two municipalities of Southern Brazil in 1996. Frequency and type of chemical exposure and pesticide poisoning were recorded for both sexes. All subjects aged 15 years or older with at least 15 weekly hours of agricultural activity were interviewed. An adapted questionnaire developed by the American Thoracic Society was used for the assessment of respiratory symptoms. Multivariate logistic regression analysis was carried out. RESULTS: More than half (55% of interviewees were male. The prevalence of asthma symptoms was 12% and chronic respiratory disease symptoms was 22%. Higher odds ratios for both asthma (OR=1.51; 95% CI: 1.07-2.14 and chronic respiratory disease (OR=1.34; 95% CI 1.00-1.81 symptoms were found in women. Logistic regression analysis identified associations between many forms of exposure to pesticides and increased respiratory symptoms. Occurrence of pesticide poisoning was associated with higher prevalence of asthma symptoms (OR=1.54; 95% CI: 1.04-2.58 and chronic respiratory disease symptoms (OR=1.57; 95% CI: 1.08-2.28. CONCLUSIONS: In spite of causality limitations, the study results provide evidence that farming exposure to pesticides is associated with higher prevalence of respiratory symptoms, especially when the exposure is above two days per month.

    Patients with chronic obstructive pulmonary disease (COPD) usually complain of symptoms such as cough, sputum, wheezing, and dyspnea. Little is known about clinical symptoms in individuals with restrictive ventilatory impairment. The aim of this study was to compare the prevalence and type of respiratory symptoms in patients with COPD to those reported by individuals with restrictive ventilatory impairment in the Proyecto Latinoamericano de Investigacion en Obstruccion Pulmonar study. Between 2002 and 2004, individuals ≥40 years of age from five cities in Latin America performed pre and post-bronchodilator spirometry and had their respiratory symptoms recorded in a standardized questionnaire. Among the 5315 individuals evaluated, 260 (5.1%) had a restrictive spirometric diagnosis (forced vital capacity (FVC) normal (LLN) with forced expiratory volume in the first second to forced vital capacity ratio (FEV1/FVC) ≥ LLN; American Thoracic Society (ATS)/European Respiratory Society (ERS) 2005) and 610 (11.9%) were diagnosed with an obstructive pattern (FEV1/FVC < LLN; ATS/ERS 2005). Patients with mild restriction wheezed more ((30.8%) vs. (17.8%); p < 0.028). No difference was seen in dyspnea, cough, and sputum between the two groups after adjusting for severity stage. The health status scores for the short form 12 questionnaire were similar in restricted and obstructed patients for both physical (48.4 ± 9.4 vs. 48.3 ± 9.8) and mental (50.8 ± 10.6 vs. 50.0 ± 11.5) domains. Overall, respiratory symptoms are not frequently reported by patients with restricted and obstructed patterns as defined by spirometry. Wheezing was more frequent in patients with restricted pattern compared with those with obstructive ventilatory defect. However, the prevalence of cough, sputum production, and dyspnea are not different between the two groups when adjusted by the same severity stage. PMID:26041119

    Abstract Cannabis smoking can create respiratory problems. Vaporizers heat cannabis to release active cannabinoids, but remain cool enough to avoid the smoke and toxins associated with combustion. Vaporized cannabis should create fewer respiratory symptoms than smoked cannabis. We examined self-reported respiratory symptoms in participants who ranged in cigarette and cannabis use.

    Scheduled and/or thoracic, abdominal surgeries increase the risk of respiratory postoperative complications. In patients with chronic respiratory failure, preoperative evaluation should be performed to evaluate respiratory function in aim to optimize perioperative management. Preoperative gas exchange abnormalities (hypoxemia or hypercapnia) are associated with respiratory postoperative complications. Respiratory physiotherapy and prophylactic non-invasive ventilation should be integrated in a global rehabilitation management for cardiothoracic or abdominal surgery procedures, which are at high risk of postoperative respiratory dysfunction. Stopping tobacco consummation should be benefit, but decease risk of postoperative complications is relevant only after a period for 6 to 8 weeks of cessation. Bronchodilatator aerosol therapy (beta-agonists and atropinics) and inhaled corticotherapy allow a rapid preparation for 24 to 48 h. Systematic preoperative antibiotherapy should not be recommended.

    1994-10-01

    In a study among 194 male workers exposed to endotoxin-containing organic dust in animal feed mills, lung function was measured by flow volume curves and impedance measurements and respiratory symptoms were recorded by means of a validated questionnaire. The aims were to detect and localize airway obstruction caused by fodder dust and endotoxin, and to relate respiratory symptoms to both types of lung function measurements. Flow volume and impedance parameters were significantly related to present exposure. All impedance parameters, of the spirometric measures only FEF25, were significantly related to cumulative dust or endotoxin exposure. The changes in impedance parameters were for overall increasing resistance at 8 Hz and decreasing reactance at 8 Hz, reflecting an increase in peripheral airflow obstruction, with increasing exposure. The changes in all lung function parameters were more strongly related to (cumulative) endotoxin exposure than to inspirable dust exposure. All impedance parameters and FEV1 showed a good correlation with complaints of chronic bronchitis and breathlessness. Impedance measurement of the respiratory system proved to be a useful tool for objectively assessing (early) airflow obstruction in workers exposed to inspirable dust and endotoxin and in localizing airflow obstruction.

    symptoms in the European Community Respiratory Health Study (ECRHS varied from one percent to 35% 1. In fact, two studies have reported that more than half of the adult population suffers from one or more respiratory symptoms 45. Respiratory symptoms are important markers of the risk of having or developing disease. Respiratory symptoms have been shown to be predictors for lung function decline 678, asthma 910, and even all-cause mortality in a general population study 11. In patients with a known diagnosis of asthma or chronic obstructive pulmonary disease (COPD, respiratory symptoms are important determinants of reduced health related quality of life (HRQoL 12131415. The prevalence of respiratory symptoms exceeds the combined prevalences of asthma and COPD, and both asthma and COPD are frequently undiagnosed diseases 161718. Thus, the high prevalence of respipratory symptoms may mirror undiagnosed and untreated disease. The common occurrence of respiratory symptoms calls for attention to how these symptoms affect health also in subjects with no diagnosis of obstructive airways disease. Impaired HRQoL in the presence of respiratory symptoms have been found in two population-based studies 619, but no study of respiratory sypmtoms and HRQoL have separate analyses for subjects with and without asthma and COPD, and no study provide information about extensive objective measurements of respiratory health. The ECRHS is a randomly sampled, multi-cultural, population based cohort study. The ECRHS included measurements of atopy, bronchial hyperresponsiveness (BHR, and lung function, and offers a unique opportunity to investigate how respiratory symptoms affect HRQoL among subjects both with and without obstructive lung disease. In the present paper we aimed to: 1 Describe the relationship between respiratory symptoms and HRQoL in an international adult general population and: 2 To assess whether this relationship varied with presence of asthma and/or COPD, or presence of objective

    The respiratory effects of diphenylmethane diisocyanate (MDI)-based resins and ureaformol- and formophenolic-based resins, used in coal mining, are unknown. This cross-sectional study of 354 miners evaluated respiratory health in miners with MDI-related symptoms (IS) and ureaformol/formophenolic-related symptoms (UFS). The protocol included clinical examination, chest radiograph, questionnaire on respiratory symptoms, smoking habit, job history, resin handling, and spirometry. Resin handling concerned 27.7% of the miners. IS affected 5.6%, and 1.4% also after work. UFS affected 22.6%, and 2.3% also after work. Wheezing affected 35.6%; chronic cough, expectoration, or bronchitis about 10%; dyspnea 5.4%; and asthma 2.8%. The miners with UFS had significantly more frequent chronic cough, expectoration, chronic bronchitis, dyspnea, and wheezing, whereas those with IS at and after work had markedly lower FVC, FEV1, MMEF, FEF50% and FEF25%. These findings raise the possibility of deleterious effects of exposures to MDI and ureaformol/ ormophenolic resins on respiratory health and lung function in coal miners during their working life.

    2011-03-01

    Respiratory insufficiency is a frequent feature of ALS and is present in almost all cases at some stage of the illness. It is the commonest cause of death in ALS. FVC is used as important endpoint in many clinical trials, and in decision-making events for patients with ALS, although there are limitations to its predictive utility. There are multiple causes of respiratory muscle failure, all of which act to produce a progressive decline in pulmonary function. Diaphragmatic fatigue and weakness, coupled with respiratory muscle weakness, lead to reduced lung compliance and atelectasis. Increased secretions increase the risk of aspiration pneumonia, which further compromises respiratory function. Bulbar dysfunction can lead to nutritional deficiency, which in turn increases the fatigue of respiratory muscles. Early recognition of respiratory decline and symptomatic intervention, including non-invasive ventilation can significantly enhance both quality of life and life expectancy in ALS. Patients with respiratory failure should be advised to consider an advance directive to avoid emergency mechanical ventilation.

    The goal of this study was to examine the prevalence of chronic respiratory symptoms in potroom workers and to compare these results with changes in spirometric parameters. A modified questionnaire on respiratory symptoms from the British Medical Research Council was used to take the medical history data about respiratory symptoms. Spirometric parameters were determined on the same day (as a part of regular checkups) using the Jaeger spirometer. The study included 215 potroom workers from the aluminium factory in Podgorica, Montenegro. All subjects were men, but they differed in age and duration of work. The group used for comparison consisted of 81 unemployed male applicants for jobs in the factory who had never been exposed to this kind of air pollution before. Potroom workers mostly complained of breathlessness associated with the workplace (56.7 %) or weather changes (rain, cold wind, and humidity) (41.9%) and of dyspnoea when climbing stairs (51.2 %), but only 22.3 % reported using medication to treat these episodes. Most workers reported to have been smoking at the time of the study (62.4 %). Spirometric data showed only insignificant variations compared to the expected values (CECA standards). Chronic obstructive pulmonary disease (COPD), characterised by FEV1/VC % <88 % was found in only 17 (7.9 %) potroom workers, while asthma was identified in 9 (4.2 %). Although the prevalence of chronic respiratory symptoms reported by the examined potroom workers was quite high at the group level, they were not associated with ventilatory impairments.

    The goals of the study were to determine the prevalence of obsessive or compulsive (OC) symptoms among chronic schizophrenic patients, and to elucidate the level of function and course of illness in chronic schizophrenic patients with and without such symptoms. Therapists of 102 patients with DSM-III-R diagnoses of chronic schizophrenia reported on their patients' OC symptoms, level of function, and course of illness. Twenty-five percent of the chronic schizophrenic patients presented with significant OC symptoms. The OC schizophrenics had significantly earlier onsets of their illnesses, had spent more time in the hospital in the previous 5 years, and were judged by their therapists to have a lower level of capacity for age-appropriate function. In addition, such patients had been less often employed and less often married, and were more dependent on others. The poorer prognosis for schizophrenic patients with OC symptoms than for those without these symptoms suggests the need for new therapeutic strategies for such patients. PMID:7705089

    Full Text Available Abstract Cannabis smoking can create respiratory problems. Vaporizers heat cannabis to release active cannabinoids, but remain cool enough to avoid the smoke and toxins associated with combustion. Vaporized cannabis should create fewer respiratory symptoms than smoked cannabis. We examined self-reported respiratory symptoms in participants who ranged in cigarette and cannabis use. Data from a large Internet sample revealed that the use of a vaporizer predicted fewer respiratory symptoms even when age, sex, cigarette smoking, and amount of cannabis used were taken into account. Age, sex, cigarettes, and amount of cannabis also had significant effects. The number of cigarettes smoked and amount of cannabis used interacted to create worse respiratory problems. A significant interaction revealed that the impact of a vaporizer was larger as the amount of cannabis used increased. These data suggest that the safety of cannabis can increase with the use of a vaporizer. Regular users of joints, blunts, pipes, and water pipes might decrease respiratory symptoms by switching to a vaporizer

  11. Gender differences in respiratory symptoms-Does occupation matter?

    International Nuclear Information System (INIS)

    Little attention has been given to gender differences in respiratory health, particularly in occupational settings. The purpose of this paper was to evaluate gender differences in respiratory morbidity based on surveys of hospitality workers, radiographers, and respiratory therapists. Data were available from mail surveys of 850 hospitality industry workers (participation rate 73.9%; 52.6% female), 586 radiographers (participation rate 63.6%; 85% female), and 275 respiratory therapists (participation rate 64.1%; 58.6% female). Cross-tabulations by gender were evaluated by χ2 analysis and logistic regression with adjustment for personal and work characteristics. Women consistently had greater respiratory morbidity for symptoms associated with shortness of breath, whereas men usually had a higher prevalence of phlegm. There were few differences in work exposures apart from perception of exposure to ETS among hospitality workers. Gender differences in symptoms were often reduced after adjustment for personal and work characteristics but for respiratory therapists there were even greater gender disparities for asthma attack and breathing trouble. Population health findings of elevated symptoms among women were only partially supported by these occupational respiratory health surveys. The influence of differential exposures and personal factors should be considered when interpreting gender differences in health outcomes

    Full Text Available This cross-sectional study was conducted in a foundry factory to assess the prevalence of respiratory symptoms and occupational asthma in foundry workers. Physical examination, spirometric evaluation, chest radiograph, and a questionnaire related to respiratory symptoms were performed. Monitoring of peak expiratory flow rates, spirometric reversibility test, and high-resolution computed tomographies were performed for the participants having respiratory symptoms and/or impaired respiratory function test. A total of 347 participants including 286 workers from production department and 61 subjects who worked in nonproduction departments were enrolled in this study. It is found that phlegm (n: 71, 20.46% and cough (n: 52, 14.98% were the most frequent symptoms. The other symptoms were breathlessness (n: 28, 8.06%, chest tightness (n: 14, 4.03%, and wheezing (n: 7, 2.01% . The prevalence of occupational asthma was found to be more frequent among the subjects who worked in the production department (n: 48, 16.78% than the other persons who worked in the nonproduction department (n: 3, 4.91% by chi-square test (P: 0.001. To prevent hazardous respiratory effects of the foundry production, an early diagnosis of occupational asthma is very important. Cessation of cigarette smoking and using of protective masks during the working time should be encouraged.

    Full Text Available BACKGROUND: The relationship between patient-reported symptoms and objective measures of lung function is poorly understood. AIM: To determine the association between responsiveness to bronchodilator and respiratory symptoms in random population samples. METHODS: 4669 people aged 40 years and older from 8 sites in Canada completed interviewer-administered respiratory questionnaires and performed spirometry before and after administration of 200 ug of inhaled salbutamol. The effect of anthropometric variables, smoking exposure and doctor-diagnosed asthma (DDA on bronchodilator responsiveness in forced expiratory volume in 1 second (FEV1 and in forced vital capacity (FVC were evaluated. Multiple logistic regression was used to test for association between quintiles of increasing changes in FEV1 and in FVC after bronchodilator and several respiratory symptoms. RESULTS: Determinants of bronchodilator change in FEV1 and FVC included age, DDA, smoking, respiratory drug use and female gender [p<0.005 to p<0.0001 ]. In subjects without doctor-diagnosed asthma or COPD, bronchodilator response in FEV1 was associated with wheezing [p for trend<0.0001], while bronchodilator response for FVC was associated with breathlessness. [p for trend <0.0001]. CONCLUSIONS: Bronchodilator responsiveness in FEV1 or FVC are associated with different respiratory symptoms in the community. Both flow and volume bronchodilator responses are useful parameters which together can be predictive of both wheezing and breathlessness in the general population.

    Chronic idiopathic urticaria (CIU) is a frequently disabling disease with a negative influence on the quality of life, and can cause psychopathological symptoms, such as anxiety. Our aim is to study further anxiety symptoms on CIU patients. Both CIU patients and the control group were studied by means of validated scales for psychopathology symptoms, psychological variables and quality of life. In this study, we reported high levels of anxiety symptoms. We found statistically significant correlations between anxiety symptoms, some personality dimensions, insecure attachment styles, alexithymia and with some quality of life dimensions. CIU patients exhibit high levels of psychological distress that could potentiate difficulties at several domains, namely social, emotional, general health perception and interpersonal relationships.

    Full Text Available Abstract Background Specific occupations are associated with adverse respiratory health. Inhalation exposures encountered in these jobs may place workers at risk of new-onset respiratory disease. Methods We analyzed data from 8,967 participants from the Atherosclerosis Risk in Communities (ARIC study, a longitudinal cohort study. Participants included in this analysis were free of chronic cough and phlegm, wheezing, asthma, chronic bronchitis, emphysema, and other chronic lung conditions at the baseline examination, when they were aged 45-64 years. Using data collected in the baseline and first follow-up examination, we evaluated associations between occupation and the three-year incidence of cough, phlegm, wheezing, and airway obstruction and changes in forced expiratory volume in one second (FEV1 and forced vital capacity (FVC measured by spirometry. All associations were adjusted for age, cigarettes per day, race, smoking status, and study center. Results During the approximately three-year follow-up, the percentage of participants developing chronic cough was 3%; chronic phlegm, 3%; wheezing, 3%; and airway obstruction, defined as FEV1 1/FVC 1 and FVC were 56 mL and 66 mL, respectively, among men and 40 mL and 52 mL, respectively, among women. Relative to a referent category of managerial and administrative support occupations, elevated risks of new-onset chronic cough and chronic phlegm were observed for mechanics and repairers (chronic cough: RR: 1.81, 95% CI: 1.02, 3.21; chronic phlegm: RR: 2.10, 95% CI: 1.23, 3.57 and cleaning and building service workers (chronic cough: RR: 1.85, 95% CI: 1.01, 3.37; chronic phlegm: RR: 2.28, 95% CI: 1.27, 4.08. Despite the elevated risk of new-onset symptoms, employment in cleaning and building services was associated with attenuated lung function decline, particularly among men, who averaged annual declines in FEV1 and FVC of 14 mL and 23 mL, respectively, less than the declines observed in the

    Full Text Available Capsaicin causes direct irritation of the eyes, mucous membranes, and respiratory tract. It is used in self-defense, in crowd control, and as a less lethal weapon in police work. Controlled trials suggest that capsaicin has minimal serious acute effects. Herein, we report a woman who had a 20-minute exposure to capsaicin during a jail riot. She subsequently developed episodic dyspnea and cough, and increased sensitivity to scents, perfumes, and cigarette smoke. She has not had wheezes on physical examination or abnormal pulmonary function tests. Her response to inhaled steroids and long-acting beta-agonists has been incomplete. She appears to have developed airway sensory hyperreactivity syndrome after the inhalation of capsaicin, which likely injured sensory nerves and/or caused persistent neurogenic inflammation.

    Full Text Available Abstract Background Occupational risk factors are one of the major causes of respiratory illnesses and symptoms, and account for 13% of chronic obstructive pulmonary disease and 11% of asthma worldwide. Majority of brick kilns in Pakistan use wood and coal for baking the bricks which makes the brick kiln workers susceptible to high exposure of air pollution. This study was designed to describe frequency of chronic respiratory symptoms and illnesses and study the association between these symptoms and different types of work. Methods This was a questionnaire based cross sectional survey conducted among the brick kiln workers in Larkana and Dadu districts, Sindh, Pakistan. A total of 340 adult men were assessed using translated version of the American Thoracic Society Division of Lung Disease (ATS-DLD questionnaire. Logistic regression analysis was done to determine the relationship between various socio-demographic and occupational factors (age, education, type of work, number of years at work, smoking status, and the respiratory symptoms and illnesses (chronic cough, chronic phlegm, wheeze, Chronic Bronchitis and asthma. Results Results of the study show that 22.4% workers had chronic cough while 21.2% reported chronic phlegm. 13.8% had two or more attacks of shortness of breath with wheezing. 17.1% workers were suffering from Chronic Bronchitis while 8.2% reported physician diagnosed asthma. Amongst the non-smoking workers 8.9% had Chronic Bronchitis. Multivariate analysis found that workers involved in brick baking were more likely to have Chronic Bronchitis (OR= 3.7, 95% CI 1.1-11.6, p= Conclusion A high frequency of respiratory symptoms and illnesses was observed among brick kiln workers. Age, nature of work and smoking were strong predictors of developing these symptoms and illnesses.

    The aim of this paper was to study the effect of pets and other domestic animals effect on allergic respiratory symptoms among United Arab Emirates primary school children. A cross-sectional survey of 2200 school children living in both urban and rural areas was conducted using self-administered questionnaires between November 1993 and June 1994. The age range of the children studied was 6-12 years, with a mean of 9.23 and standard deviation of 2.14 years; 51% were girls and 49% were boys. Pet ownership was defined by the presence of birds, cats, camels, dogs, goats, poultry and rabbits in the home. One thousand and thirty-six (1036/2090 = 49.6%) of the 2090 families studied had at least one animal at home. However, respiratory symptoms, pet allergy, chronic cough, chronic wheeze, breathlessness or chest tightness, doctor-diagnosed asthma, rhinitis and eczema was reported by 633 families (30.3%) from 2090 studied families. The highest prevalence of reported respiratory allergy and symptoms was found in children who had pets in the past and currently. The lowest prevalence of reported respiratory allergy and symptoms was found in children who never had pets in their lives. Past pets ownership was generally associated with a higher prevalence of pets allergy and respiratory symptoms. No less than 218 (10.4%) reported removing pets in the past because of an allergy or other health problems in the child or in other family members. The risk of having pet allergy in children with animals was found to be twice than that of children without (RR: 2.13; 95% CI: 1.53-2.97; p < 0.0001).(ABSTRACT TRUNCATED AT 250 WORDS) PMID:7626193

    The aim of this study was to determine the prevalence of some respiratory symptoms and possible diseases among occupationally-exposed garage workers and taxi drivers. This study involved 158 garage workers and 165 taxi drivers, matched for age, sex, nationality and duration of employment. The mean age of 158 Indian subcontinent garage workers was 34.4 +/- 10.4 years; their mean height and weight were 167.7 +/- 6.6 cm and 72.0 +/- 12.3 kg respectively, and the mean duration of employment garage workers was 8.8 +/- 7.6 years. The mean age of 165 Indian subcontinent male taxi drivers was 34.5 +/- 7.7 years; their mean height and weight were 168.7 +/- 6.1 cm and 71.3 +/- 12.6 kg respectively; and the mean duration of employment was 7.5 +/- 5.4 years. The data on chronic respiratory symptoms showed that garage workers had higher prevalence of symptoms than taxi drivers being significantly greater for chronic phlegm, (p taxi drivers, although the differences were significant only for throat (p pain (p taxi drivers. The results of stepwise multiple regression analysis showed that only phlegm, sinusitis, hearing problems, nasal catarrh, throat, low back pain, smoking and FEF25-75, variables were statistically significant predictors as risk factors. In conclusion, the present study suggests that a high prevalence of respiratory symptoms is associated with exposure to motor vehicle exhaust emission in garage working places. Long-term working as garage workers in the United Arab Emirates (UAE), may be associated with the development of chronic respiratory symptoms and have effects on their daily life and health.

Respiratory symptoms included cough (28%, sputum (23%, wheezing (22% and dyspnea (8%. These symptoms were associated with alcoholism, AOR: 3.1 (1.2-8.4; less than 4 years of schooling, AOR: 5.0 (1.4-17.7; and previous pulmonary diseases, AOR: 5.4 (1.7-17.3. Forty-one percent (95% CI, 29-56 had pulmonary disorders, of which the most prevalent were obstructive disorders (49%, followed by obstructive disorder with reduced forced vital capacity disorders (46% and restrictive disorders (5%. The lifestyle difference could not explain differences in chronic symptoms and/or the prevalence of pulmonary dysfunction.CONCLUSION:The high prevalence of chronic respiratory symptoms and pulmonary dysfunction in post-tuberculosis patients indicates a need for further interventions to reduce social vulnerability of patients successfully treated for tuberculosis.

    Over the last decades, concentrations of air pollution components such as SO{sub 2} and airborne, coarse particulates have decreased in many areas in Europe. This decrease can be ascribed to emission abatement measures and changes in energy production for industrial processes and space heating. Levels of other pollutants such as NO{sub 2} have increased during the same period, mostly due to higher intensity of motor vehicle traffic. Older epidemiologic studies on health effects of air pollution used indicator pollutants such as SO{sub 2}, Total Suspended Particulate matter (TSP) and Black Smoke at extremely high levels. More recent studies using the same and other indicators such as PM10 (particles with a median aerodynamic diameter of 10 {mu}m) have shown effects of air pollution on mortality and morbidity at lower levels, even sometimes lower than current WHO air quality guidelines for Europe. These findings suggest that due to the changing composition of air pollution, effects of air pollution can be seen below levels of exposure which were thought to be safe. Another reason is that the recent studies are conducted at levels which were hard to find in earlier days. Therefore new, quantitative data are needed to evaluate the current guidelines and standards. In order to achieve this, standardization of methodology as well as the execution of epidemiologic studies using such standardized methodology is needed. In the framework of the ENVIRONMENT Research Programme of the Commission of the European Communities, a collaborative study was funded that sought to develop a standardized methodology for epidemiologic studies of effects short-term changes in air pollution on the respiratory system

    Several studies have investigated the effect of livestock farm emissions on the respiratory health of local residents, but results are inconsistent. This study aims to explore associations between the presence of livestock farms and respiratory health in an area of high-density livestock farming in the Netherlands. We focused especially on associations between farm exposures and respiratory symptoms within subgroups of potentially susceptible patients with a pre-existing lung disease.In total, 14 875 adults (response rate 53.4%) completed a questionnaire concerning respiratory health, smoking habits and personal characteristics. Different indicators of livestock farm exposures relative to the home address were computed using a geographic information system.Prevalence of chronic obstructive pulmonary disease (COPD) and asthma was lower among residents living within 100 m of a farm (OR 0.47, 95% CI 0.24-0.91 and OR 0.65, 95% CI 0.45-0.93, respectively). However, >11 farms in 1000 m compared to fewer than four farms in 1000 m (fourth quartile versus first quartile) was associated with wheezing among COPD patients (OR 1.71, 95% CI 1.01-2.89). Using general practitioners' electronic medical records, we demonstrated that selection bias did not affect the observed associations.Our data suggest a protective effect of livestock farm emissions on the respiratory health of residents. Nonetheless, COPD patients living near livestock farms reported more respiratory symptoms, suggesting an increased risk of exacerbations. PMID:26250492

This study was undertaken to determine the prevalence of various respiratory symptoms and assess pulmonary function among farmers around the city of Chandigarh. An attempt was also made to identify the types of farming that may be associated with these symptoms. A house-to-house survey was carried out in seven villages around Chandigarh with the help of a questionnaire that was used in our earlier surveys. Lung function tests were carried out using a portable spirometer. Out of the 486 farmers included in the study, 106(21.8% were symptomatic: chronic bronchitis (n=34, cough (n=38, bronchial asthma (n=13, post nasal drip (n=9, chest tightness (n=8 and dyspnea (n=4. The respiratory symptoms were more common among non-smokers (55.6% than smokers (44.3%. Combined type of farming work was associated most often with respiratory symptoms followed by grain cutting. Pulmonary function parameters had lower values in smokers than in non-smokers and in symptomatic than in asymptomatic sybjects.

    @@ Chronic Mountain Sickness (CMS) is a multifactorial disease caused by a limited capacity to achieve complete adaptation to life under chronic hypoxic conditions. It is accompanied by excessive erythrocitosis (levels of erythrocytes above the normal value set for each altitude), and in advances cases also by pulmonary hypertension. The hypoxemia, caused by central or peripheral respiratory disorders and/or associated to diverse risk factors, produces the excessive erythrocytosis. The most common symptoms are headaches, dizziness, breathlessness, sleep disturbances, tinnitus, physical and mental fatigue, anorexia, and bone and muscle pain. The most common signs are an intermittent or permanent cyanosis, hyperemia and venous dilatation in hands or feet (Monge-M et al., 1928; Winslow and Monge-C, 1987). Aging, respiratory diseases, sleep, menopause, and overweight has proved to be additional risk factors in the development of CMS (Kryger et al., 1978; León-Velarde et al., 1993; Sime et al., 1975; León-Velarde et al., 1997; León-Velarde et al., 2001; Monge-C et al., 1992; Normand et al., 1992)

    Full Text Available Abstract Background Gastro-oesophageal reflux disease (GORD symptoms are common in asthma and have been extensively studied, but less so in the Asian continent. Reflux-associated respiratory symptoms (RARS have, in contrast, been little-studied globally. We report the prevalence of GORD symptoms and RARS in adult asthmatics, and their association with asthma severity and medication use. Methods A cross-sectional analytical study. A validated interviewer-administered GORD scale was used to assess frequency and severity of seven GORD symptoms. Subjects were consecutive asthmatics attending medical clinics. Controls were matched subjects without respiratory symptoms. Results The mean (SD composite GORD symptom score of asthmatics was significantly higher than controls (21.8 (17.2 versus 12.0 (7.6; P P Conclusions GORD symptoms and RARS were more prevalent in a cohort of Sri Lankan adult asthmatics compared to non-asthmatics. Increased prevalence of RARS is associated with both typical and atypical symptoms of GORD. Asthma disease and its severity, but not asthma medication, appear to influence presence of GORD symptoms.

  12. Prevalence of respiratory symptoms and their correlation to pulmonary function abnormalities in individuals exposed to environmental pollution

    International Nuclear Information System (INIS)

    To find out the prevalence of respiratory symptoms and their correlation to pulmonary function abnormalities in individuals exposed to polluted air, 438 workers, and their family members were studied at Thermal Power Station (TPS), Sheikhmanda (Quetta). Individuals with a stay of less than three years at TPS and patients with known chronic respiratory infections (tuberculosis and its squelae, bronchiectasis) were excluded from the study. Remaining 175 males (mean age 43.4 years) and 71 females (mean age 34.2 years) were divided into three groups A, B, C on the basis of their exposure time to polluted air per day during the three years. Each groups was further subdivided into smoker and non-smoker members. Prevalence of respiratory symptoms was significantly higher in the individuals exposed to polluted air as compared to non-exposed individuals (P<0.05). A strong positive correlation (r=0.91) exists between respiratory symptoms and respiratory function abnormalities in smoker groups; however, no definite correlation (r=0.06) was found between respiratory symptoms and respiratory function abnormalities in non-smoker groups. Function abnormalities was noted only in smoker groups and non-smokers of even maximally exposed group (group C) had almost no respiratory function abnormalities. (author)

  13. Chronic candidiasis - pathogenesis, symptoms, diagnosis and treatment

    Full Text Available The yeast named Candida normally colonizes the gut and vagina without causing any sign of its presence. It is a commensal and opportune fungus but in certain conditions it turns to be pathogenic, causing chronic disturbances in any part of the body. The pathogenesis is complex, signs and symptoms are non-specific. The colonisation is difficult to distinguish from invasive disease. The current diagnostic methods do not always allow a definitive diagnosis to be made. Treatment is complex, individual and no protocol can be created. The author tries to give an overview of the Candida related problem.

    Full Text Available While research has documented the adverse impact of agricultural work on the respiratory health of farmers, few studies have reported on the respiratory health of dairy workers. Additionally, we are not aware of any published studies addressing the health impacts associated with large dairies in the western United States. The present investigation is a cross-sectional survey carried out at 13 dairies throughout the San Joaquin Valley. Data were collected from 232 dairy workers and 52 employees of a control facility (a vegetable processing plant during a three-month period in 2008. Survey data collected included: socioeconomic status, respiratory health history, respiratory exposure history, work history, and current health symptoms. The dairy and control populations were almost all immigrant Latino and were similar in demographics, with two primary exceptions: dairy workers had higher incomes and had lived in the United States longer than the control employees. A substantial proportion of workers had never sought medical attention in the United States. Dairy work in California was associated with a significantly increased prevalence of asthmatic symptoms but not with significantly increased chronic cough, phlegm, or wheezing.Alors que de nombreuses études ont documenté les conséquences délétères des travaux agricoles sur le système respiratoire des agriculteurs, peu d’études se sont intéressées à la santé respiratoire des ouvriers des laiteries. De plus, à notre connaissance, aucune étude portant sur les conséquences en matière de santé du travail dans les grandes laiteries de l’ouest des Etats-Unis n’a été publiée. Ce travail de recherche est une étude transversale réalisée dans 13 laiteries de la San Joaquin Valley.

    Full Text Available "nBackground: Asthma is a life-threatening disease that can cause death due to bronchospasm. In addition to clinical symptoms such as wheezing, acute paroxysmal dyspnea, chronic cough after exposure to cold air or cough after exercise, spirometry is also necessary for the diagnosis of asthma. The association between respiratory symptoms and a positive methacholine challenge test (MCT is still controversial. The aim of this study was to determine the association between methacholine test results and respiratory symptoms and allergy."n "nMethods: One hundred and forty-six patients with respiratory symptoms and normal baseline pulmonary function tests were enrolled in this cross-sectional study. The participants were divided into two groups according to their positive or negative response to MCT. The association between MCT and the clinical symptoms and allergy was later evaluated statistically."n "nResults: Out of 146 participants of the study 59 (40.4% were female and 87 (59.6% were male. The mean age of the participants was 33.8±13.8 years. Sixty-one patients (41.8% had positive results for the test. There was an association between a history of allergy, wheezing and age with positive MCT results. The other clinical signs had no association with the test."n "nConclusion: Methacholine challenge test is the best diagnostic test for ruling out asthma in patients with normal pulmonary function tests in whom we cannot definitely rule out asthma based solely on clinical symptoms. Nevertheless, in adults with a history of allergy, wheezing and also in patients below 30, the probability for a positive MCT is high.

    2015-01-01

    Full Text Available Chronic dyspnea, chest pain, cough, and hemoptysis for more than 2 weeks often indicate a diagnosis of infective etiology of the respiratory tract in a tropical country. However, in a young reproductive female, these complaints with an episode of hemoptysis may rarely be the presenting symptomatology of pulmonary metastasis of choriocarcinoma. A young female of reproductive age group presented with hemoptysis, cough, and breathlessness. Chest X-ray revealed bilateral lower lobe opacities. Fine-needle aspiration cytology of the lung lesions depicted choriocarcinoma metastasis. Ultrasonography and magnetic resonance imaging revealed endomyometrial mass lesion suggestive of invasive gestational trophoblastic disease. β hCG levels were high. Dilatation and curettage and histopathological analysis of the mass confirmed the diagnosis of choriocarcinoma. This young female who presented with respiratory complaints was finally diagnosed to be a case of choriocarcinoma with lung metastasis. Therefore, choriocarcinoma metastasis must be considered as a differential diagnosis in a female of childbearing age presenting with respiratory complaints and hemoptysis.

  8. High rates of detection of respiratory viruses in tonsillar tissues from children with chronic adenotonsillar disease.

    Directory of Open Access Journals (Sweden)

    Jose Luiz Proenca-Modena

    Full Text Available Chronic tonsillar diseases are an important health problem, leading to large numbers of surgical procedures worldwide. Little is known about pathogenesis of these diseases. In order to investigate the role of respiratory viruses in chronic adenotonsillar diseases, we developed a cross-sectional study to determine the rates of viral detections of common respiratory viruses detected by TaqMan real time PCR (qPCR in nasopharyngeal secretions, tonsillar tissues and peripheral blood from 121 children with chronic tonsillar diseases, without symptoms of acute respiratory infections. At least one respiratory virus was detected in 97.5% of patients. The viral co-infection rate was 69.5%. The most frequently detected viruses were human adenovirus in 47.1%, human enterovirus in 40.5%, human rhinovirus in 38%, human bocavirus in 29.8%, human metapneumovirus in 17.4% and human respiratory syncytial virus in 15.7%. Results of qPCR varied widely between sample sites: human adenovirus, human bocavirus and human enterovirus were predominantly detected in tissues, while human rhinovirus was more frequently detected in secretions. Rates of virus detection were remarkably high in tonsil tissues: over 85% in adenoids and close to 70% in palatine tonsils. In addition, overall virus detection rates were higher in more hypertrophic than in smaller adenoids (p = 0.05, and in the particular case of human enteroviruses, they were detected more frequently (p = 0.05 in larger palatine tonsils than in smaller ones. While persistence/latency of DNA viruses in tonsillar tissues has been documented, such is not the case of RNA viruses. Respiratory viruses are highly prevalent in adenoids and palatine tonsils of patients with chronic tonsillar diseases, and persistence of these viruses in tonsils may stimulate chronic inflammation and play a role in the pathogenesis of these diseases.

  9. Contribution of nitrogen oxide and sulfur dioxide exposure from power plant emissions on respiratory symptom and disease prevalence

    International Nuclear Information System (INIS)

    This study investigates the association between exposure to ambient NOx and SO2 originating from power plant emissions and prevalence of obstructive pulmonary disease and related symptoms. The Orot Rabin coal-fired power plant is the largest power generating facility in the Eastern Mediterranean. Two novel methods assessing exposure to power plant-specific emissions were estimated for 2244 participants who completed the European Community Respiratory Health Survey. The “source approach” modeled emissions traced back to the power plant while the “event approach” identified peak exposures from power plant plume events. Respiratory symptoms, but not prevalence of asthma and COPD, were associated with estimates of power plant NOx emissions. The “source approach” yielded a better estimate of exposure to power plant emissions and showed a stronger dose–response relationship with outcomes. Calculating the portion of ambient pollution attributed to power plants emissions can be useful for air quality management purposes and targeted abatement programs. -- Highlights: • Two methods assessing NOx and SO2 exposure attributed to a coal-fired power plant are utilized. • Exposure estimates are compared with respiratory outcomes in 2244 participants. • Power plant nitrogen oxide emissions are associated with respiratory symptoms. • Stack emission models correlated closest with health outcomes. -- Chronic cough, nocturnal dyspnea, chronic phlegm, and shortness of breath were significantly associated with exposure estimates of power plant-specific NOx emissions

    This purpose of this study was to examine the relationship between exposure to wheat flour, soya flour and fungal amylase and the development of work-related symptoms and sensitization in bread and cake bakery employees who have regular exposure to these substances. The study populations consisted of 394 bread bakery workers and 77 cake bakery workers whose normal jobs involved the sieving, weighing and mixing of ingredients. The groups were interviewed with the aim of identifying the prevalence, nature and pattern of any work-related respiratory symptoms. They were also skin-prick tested against the common bakery sensitizing agents, i.e., wheat flour, soya flour, rice flour and fungal amylase. The results of personal sampling for sieving, weighing and mixing operations at the bakeries from which the study groups were taken were collated in order to determine typical exposures to total inhalable dust from the ingredients, expressed as 8 hour time-weighted average exposures. Data from the health surveillance and collated dust measurements were compared with the aim of establishing an exposure-response relationship for sensitization. The prevalence of work-related symptoms in bread bakery and cake bakery ingredient handlers was 20.4% and 10.4% respectively. However, in a large proportion of those reporting symptoms in connection with work, the symptoms were intermittent and of short duration. It is considered that the aetiology of such symptoms is likely to be due to a non-specific irritant effect of high total dust levels, rather than allergy. None of the cake bakers and only 3.1% of the bread bakers had symptoms which were thought to be due to allergy to baking ingredients. Using skin-prick testing as a marker of sensitization, the prevalence of positive tests to wheat flour was 6% for the bread bakers and 3% for the cake bakers. Comparable prevalences for soya flour were 7% and 1% respectively. However, the prevalence of positive skin-prick tests to fungal amylase

    Despite aggressive antimicrobial therapy, many respiratory pathogens persist in the lung, underpinning the chronic inflammation and eventual lung decline that are characteristic of respiratory disease. Recently, bile acid aspiration has emerged as a major comorbidity associated with a range of lung diseases, shaping the lung microbiome and promoting colonisation by Pseudomonas aeruginosa in Cystic Fibrosis (CF) patients. In order to uncover the molecular mechanism through which bile modulates the respiratory microbiome, a combination of global transcriptomic and phenotypic analyses of the P. aeruginosa response to bile was undertaken. Bile responsive pathways responsible for virulence, adaptive metabolism, and redox control were identified, with macrolide and polymyxin antibiotic tolerance increased significantly in the presence of bile. Bile acids, and chenodeoxycholic acid (CDCA) in particular, elicited chronic biofilm behaviour in P. aeruginosa, while induction of the pro-inflammatory cytokine Interleukin-6 (IL-6) in lung epithelial cells by CDCA was Farnesoid X Receptor (FXR) dependent. Microbiome analysis of paediatric CF sputum samples demonstrated increased colonisation by P. aeruginosa and other Proteobacterial pathogens in bile aspirating compared to non-aspirating patients. Together, these data suggest that bile acid signalling is a leading trigger for the development of chronic phenotypes underlying the pathophysiology of chronic respiratory disease. PMID:27432520

    Certain environmental conditions in animal and plant production have been associated with increased frequency in respiratory illnesses, including asthma, chronic bronchitis, and hypersensitivity pneumonitis, in farmers occupationally exposed in swine production. The aim of this study was to characterize particulate matter (PM) contamination in seven Portuguese swine farms and determine the existence of clinical symptoms associated with asthma and other allergy diseases, utilizing the European Community Respiratory Health Survey questionnaire. Environmental assessments were performed with portable direct-reading equipment, and PM contamination including five different sizes (PM0.5, PM1.0, PM2.5, PM5.0, PM10) was determined. The distribution of particle size showed the same trend in all swine farms, with high concentrations of particles with PM5 and PM10. Results from the questionnaire indicated a trend such that subjects with diagnosis of asthma were exposed to higher concentrations of PM with larger size (PM2.5, PM5, and PM10) while subjects with sneezing, runny nose, or stuffy nose without a cold or flu were exposed to higher concentrations of PM with smaller size (PM0.5 and PM1). Data indicate that inhalation of PM in swine farm workers is associated with increased frequency of respiratory illnesses. PMID:24168036

    Full Text Available Objectives: Studies have correlated second hand smoke (SHS with many diseases, especially respiratory effects. The goal of this study was to measure the impact of SHS on the respiratory symptoms and exhaled carbon monoxide. Material and Methods: The study population consisted of 50 young workers in restaurants serving waterpipes, 48 university students who sit frequently in the university cafeteria where cigarette smoking is allowed and 49 university students spending time in places where smoking is not allowed. Subjects completed questionnaires on socio-demographic characteristics, respiratory symptoms and exposure to SHS. Exhaled carbon monoxide levels were measured. ANOVA and Chi-square tests were used when applicable as well as linear and logistic regression analysis. Results: Exposure to cigarette smoke in university (adjusted odds ratio (ORa = 6.06 and occupational exposure to waterpipe smoke (ORa = 7.08 were predictors of chronic cough. Being married (ORa = 6.40, living near a heavy traffic road (ORa = 9.49 or near a local power generator (ORa = 7.54 appeared responsible for chronic sputum production. Moreover, predictors of chronic allergies were: being male (ORa = 7.81, living near a local power generator (ORa = 5.52 and having a family history of chronic respiratory diseases (ORa = 17.01. Carbon monoxide levels were augmented by the number of weekly hours of occupational exposure to waterpipe smoke (β = 1.46 and the number of daily hours of exposure to cigarette smoke (β = 1.14. Conclusions: In summary, young non-smoker subjects demonstrated more chronic cough and elevated carbon monoxide levels when exposed to SHS while the effect of waterpipe was even more evident.

    Full Text Available Dyspnoea, fatigue, reduced exercise tolerance, peripheral muscle dysfunction and mood disorders are common features of many chronic respiratory disorders. Pulmonary rehabilitation successfully treats these manifestations in chronic obstructive pulmonary disease (COPD and emerging evidence suggests that these benefits could be extended to other chronic respiratory conditions, although adaptations to the standard programme format may be required. Whilst the benefits of exercise training are well established in asthma, pulmonary rehabilitation can also provide evidence-based interventions including breathing techniques and self-management training. In interstitial lung disease, a small number of trials show improved exercise capacity, symptoms and quality of life following pulmonary rehabilitation, which is a positive development for patients who may have few treatment options. In pulmonary arterial hypertension, exercise training is safe and effective if patients are stable on medical therapy and close supervision is provided. Pulmonary rehabilitation for bronchiectasis, including exercise training and airway clearance techniques, improves exercise capacity and quality of life. In nonsmall cell lung cancer, a comprehensive interdisciplinary approach is required to ensure the success of pulmonary rehabilitation following surgery. Pulmonary rehabilitation programmes provide important and underutilised opportunities to improve the integrated care of people with chronic respiratory disorders other than COPD.

Aim of the study: The study aimed at estimating the prevalence rate of asthma and major respiratory symptoms among students of the Grodno Region (Western Belarus. Material and methods: The cross-sectional study was conducted in 2014 and included 833 students aged 20-40 (young adults. Physician-diagnosed respiratory diseases and symptoms were ascertained using electronic version of the ISAAC questionnaire (web LimeSurvey. Results: The prevalence of asthma was 2.88% (physician-diagnosed. The obstructive (asthmatic bronchitis (without established diagnosis of asthma was found in 5.04% of the respondents. A chronic respiratory symptom occurring in the past 12 months and suggestive of asthma included attacks of dyspnea at rest, cough (5.88% or in previous periods (8.88%, and wheezing in the chest (one of the most characteristic symptoms of asthma - 8.04%, which may indicate a higher prevalence of asthma among patients. Wheezing and wheeze without diagnosed asthma, colds or infections were reported in a small number of cases (about 1.0%. 32 respondents (3.84% can be attributed to the group of risk for asthma due to the presence of specific respiratory symptoms. Conclusions: The findings show a low prevalence of physician-diagnosed asthma among students of Western Belarus. Relatively low prevalence of allergic disorders among respondents of Belarus suggest underdiagnosis of allergic diseases, in particular of asthma. Presumably, cases of asthma might be diagnosed as spastic bronchitis, “obstructive bronchitis”, “asthmatic bronchitis”, a traditional label for clinical manifestation of asthma in medical practice in the region.

  1. The Expert Patient and Chronic Respiratory Diseases

    Full Text Available The concept of “expert patient” has been developed in the last two decades to define a patient who has a significant knowledge of his/her disease and treatment in addition to self-management skills. However, this concept has evolved over the last years, and these patients are now considered, not only to be more efficient in the management of their own condition and communicating effectively with health professionals, but to also act as educators for other patients and as resources for the last, provide feedback on care delivery, and be involved in the production and implementation of practice guidelines, as well as in the development and conduct of research initiatives. There are some barriers, however, to the integration of this new contributor to the health care team, and specific requirements need to be considered for an individual to be considered as an expert. This new player has, however, a potentially important role to improve current care, particularly in respiratory health.

    Full Text Available Abstract Background Several studies have reported an association between asthma and gastro-oesophageal reflux, but it is unclear which condition develops first. The role of obesity in mediating this association is also unclear. We explored the associations between respiratory symptoms, lung function, and gastro-oesophageal reflux symptoms in a birth cohort of approximately 1000 individuals. Methods Information on respiratory symptoms, asthma, atopy, lung function and airway responsiveness was obtained at multiple assessments from childhood to adulthood in an unselected birth cohort of 1037 individuals followed to age 26. Symptoms of gastro-oesophageal reflux and irritable bowel syndrome were recorded at age 26. Results Heartburn and acid regurgitation symptoms that were at least "moderately bothersome" at age 26 were significantly associated with asthma (odds ratio = 3.2; 95% confidence interval = 1.6–6.4, wheeze (OR = 3.5; 95% CI = 1.7–7.2, and nocturnal cough (OR = 4.3; 95% CI = 2.1–8.7 independently of body mass index. In women reflux symptoms were also associated with airflow obstruction and a bronchodilator response to salbutamol. Persistent wheezing since childhood, persistence of asthma since teenage years, and airway hyperresponsiveness since age 11 were associated with a significantly increased risk of heartburn and acid regurgitation at age 26. There was no association between irritable bowel syndrome and respiratory symptoms. Conclusion Reflux symptoms are associated with respiratory symptoms in young adults independently of body mass index. The mechanism of these associations remains unclear.

    Full Text Available Recurrent respiratory papillomatosis is a relatively uncommon disease that presents clinically with symptoms ranging from hoarseness to severe dyspnea. Human papilloma virus types 6 and 11 are important in the etiology of papillomas and are most probably transmitted from mother to child during birth. Although spontaneous remission is frequent, pulmonary spread and/or malignant transformation resulting in death has been reported. CO2 laser evaporation of papillomas and adjuvant drug therapy using lymphoblastoid interferon-alpha are the most common treatments. However, several other treatments have been tried, with varying success. In the present report, a case of laryngeal papillomatosis presenting with chronic stridor and delayed speech is described.

    Coal mine dust exposure is associated with accelerated loss of lung function. The authors assessed long-term health outcomes in two groups of underground coal miners who during previous mine surveys had shown either high rates of FEV1 decline (cases, n = 310) or relatively stable lung function (referents, n = 324). Cases and referents were matched initially for age, height, smoking status, and FEV,. The authors determined vital status for 561 miners, and obtained a follow-up questionnaire for 121 cases and 143 referents. Responses on the follow-up questionnaire were compared with those on the last previous mine health survey questionnaire. Cases showed a greater incidence of symptoms than did referents for cough, phlegm production, Grades II and III dyspnea, and wheezing, and greater incidences than referents of chronic bronchitis and self-reported asthma and emphysema. More cases than referents (15% versus 4%) left mining before retirement because of chest illnesses. After controls were applied for age and smoking, cases had twice the risk of dying of cardiovascular and nonmalignant respiratory diseases and a 3.2-fold greater risk of dying of chronic obstructive pulmonary disease than did referents. Rapid declines in FEV1 experienced by some coal miners are associated with subsequent increases in respiratory symptoms, illnesses, and mortality from cardiovascular and nonmalignant respiratory diseases.

    Background. The clinical diagnosis of pneumonia is sometimes difficult since chest radiographs are often indeterminate. In this study, we aimed to assess whether serum C-reactive protein (CRP) could assist in identifying patients with pneumonia. Methods. For one winter, all consecutive patients with acute respiratory symptoms admitted to the emergency ward of a single center were prospectively enrolled. In addition to chest radiographs, basic laboratory tests, and microbiology, serum levels of CRP were measured at entry. Results. A total of 923 (62.3%) of 1473 patients hospitalized for acute respiratory symptoms were included. Subjects with a final diagnosis of pneumonia had higher serum CRP levels (median 187 mg/L) than those with exacerbations of chronic obstructive pulmonary disease (63 mg/L) or acute bronchitis (54 mg/L, p CRP was accurate in identifying pneumonia (area under the curve 0.84, 95% CI 0.82–0.87). The multilevel likelihood ratio (LR) for intervals of CRP provided useful information on the posttest probability of having pneumonia. CRP intervals above 200 mg/L were associated with LR+ > 5, for which pneumonia is likely, whereas CRP intervals below 75 mg/L were associated with LR CRP may be a useful addition for diagnosing pneumonia in hospitalized patients with acute respiratory symptoms.

  14. Building-related risk factors and work-related lower respiratory symptoms in 80 office buildings

    International Nuclear Information System (INIS)

    We assessed building-related risk factors for lower respiratory symptoms in office workers. The National Institute for Occupational Safety and Health in 1993 collected data during indoor environmental health investigations of workplaces. We used multivariate logistic regression analyses to assess relationships between lower respiratory symptoms in office workers and risk factors plausibly related to microbiologic contamination. Among 2,435 occupants in 80 office buildings, frequent, work-related multiple lower respiratory symptoms were strongly associated, in multivariate models, with two risk factors for microbiologic contamination: poor pan drainage under cooling coils and debris in outside air intake. Associations tended to be stronger among those with a history of physician-diagnosed asthma. These findings suggest that adverse lower respiratory health effects from indoor work environments, although unusual, may occur in relation to poorly designed or maintained ventilation systems, particularly among previously diagnosed asthmatics. These findings require confirmation in more representative buildings

    limited by the small number of tested patients. P300 latency changes correlated significantly with age as well as severity of respiratory failure. P300 was also significantly delayed whether hypoxia occurred with or without hypercapnia.Conclusion: Results show a significant delay of P300 latency in patients with severe and mild respiratory failure. This was associated with subclinical encephalopathy in most patients, evidenced by a near-normal MMSE score. Apart from confirming the importance of P300 latency measurement as a marker of respiratory encephalopathy, this study asserts the causal relationship between hypoxemia and cognitive derangement. Furthermore, it promotes the early use of oxygen therapy in a selected group of patients with mild or moderate respiratory failure, who have responsibilities which involve taking rapid critical decisions.Keywords: event-related evoked potentials, hypoxic–hypercapnic encephalopathy, respiratory failure, chronic respiratory encephalopathy

    2009-09-01

    The prevalence of patients with severe COPD and chronic hypercapnic respiratory failure (CHRF) receiving non-invasive home ventilation has greatly increased. With regard to disease severity, a multidimensional assessment seems indicated. Base excess (BE), in particular, reflects the long-term metabolic response to chronic hypercapnia and thus constitutes a promising, easily accessible, integrative marker of CHRF. Infact, BE as well as nutritional status and lung hyperinflation have been identified as independent predictors of long-term survival. In addition and in a review with the literature, a broad panel of indices including frequent comorbidities are helpful for assessment and monitoring purposes of patients with CHRF. Accordingly, in view of the patients' individual risk profile, the decision about the initiation of NIV should probably not rely solely on symptoms and chronic persistent hypercapnia but include a spectrum of factors that specifically reflect disease severity. Owing to the physiologically positive effects of NIV and according to retrospective data, patients with COPD and recurrent hypercapnic respiratory decompensation and patients with prolonged mechanical ventilation and/or difficult weaning could also be considered for long-term non-invasive ventilation. This, however, has to be corroborated in future prospective trials. PMID:19750411

    In the first part of our editorial we reviewed the possible factors responsible for mucus hypersecretion in acute and chronic pulmonary diseases. The present paper presents the results of studies proving, that mucolytics are useful in adjunctive therapy of respiratory tract disorders. Mucolytic agents such as Ambroxol and N-acetylcysteine are able to alter the secretion of mucus and its physical properties which results in improvement of mucociliary clearance. Current evidence indicate, that these drugs are effective, especially in chronic obstructive pulmonary disease, asthma and acute bronchitis. They produce a modest improvement in symptom control and lung function. It has been demonstrated that there is a synergism between mucolytics and antibiotics in the treatment of exacerbation of chronic bronchitis. Moreover, they act as scavengers of reactive oxygen species. Ambroxol is able to inhibit mediator release involved in the pathogenesis of allergic inflammation. As mucolytics are cheap and well-tolerated they are beneficial in the therapy of patients suffering from respiratory tract disorders. PMID:12053601

    Full Text Available Chronic obstructive pulmonary disease (COPD has a dramatic effect on quality of life. The need to formulate a different set of parameters for peoples was felt because of the differences in risk factors, disease prevalence and pattern, and above all, the different overall health-care infrastructure. Moreover a large burden of tuberculosis, which is an important cause of cough, adds to the difficulties of diagnosis and management. Worldwide, COPD ranked as the sixth leading cause of death in 1990. It is projected to be the fourth leading cause of death worldwide by 2030 due to an increase in smoking rates and demographic changes in many countries. When the damage is severe, it may become difficult to get enough oxygen into the blood and to get rid of excess carbon dioxide. These changes lead to shortness of breath and other symptoms. Unfortunately, the symptoms of chronic obstructive pulmonary disease cannot be completely eliminated with treatment and the condition usually worsens over time. However, treatment can control symptoms and can sometime slow the progression of the disease. More than 12 million people are currently diagnosed with COPD. An additional 12 million probably have the disease and don't know it. COPD has received scant attention in comparison to other respiratory conditions such as asthma and lung cancer. Respiratory physicians around the world now believe the attitude of little can done for this self inflicted disease is not justifiable. Attempts have been made to redress this deficit with the recent introduction of guidelines in the management and care of patients with COPD by both the American Thoracic Society and European Respiratory Society. So this review provides the overall knowledge about the COPD as well as their management.

Objectives To make a systematic review to provide a detailed summary of relevant literature on the association between CPP and different psychiatric disorders/symptoms. Methods A systematic review of articles in the international literature published between 2003 and 2014 was performed in the electronic databases PubMed, PsycINFO, LILACS, and SciELO using the terms (chronic pelvic pain AND (psychiatry OR psychiatric OR depression OR anxiety OR posttraumatic stress OR somatoform. The searches returned a total of 529 matches that were filtered according to predefined inclusion and exclusion criteria. A total of 18 articles were selected. Results The investigations focused mainly on the assessment of depression and anxiety disorders/symptoms, with rather high rates (17-38.6%. Depression and anxiety symptoms were more prevalent among women with CPP compared to healthy groups. Comparisons between groups with CPP and with specific pathologies that also have pain as a symptom showed that depression indicators are more frequent in CPP. Depressive symptoms tend to be more common in CPP and have no particular association with pain itself, the core feature of CPP. Discussion Other aspects of CPP seem to play a specific role in this association. Anxiety and other psychiatric disorders require further investigation so that their impact on CPP can be better understood.

    Chronic intermittent hypoxia (CIH), a feature of obstructive sleep apnoea (OSA) has been shown to have myriad effects on the respiratory control system. The effects on breathing are of great clinical significance for the sleep apnoea patient. We sought to determine the effect of CIH on normoxic ventilation. Both male and female adult Wistar rats were studied due to the evident sex difference in the prevalence of OSA. A role for oxidative stress in respiratory modifications was also explored. Adult male (n = 30) and female (n = 16) rats were exposed to alternating periods of N(2) and O(2) for 90 s each, bringing the ambient oxygen concentration to 5% at nadir (CIH) group. Sham groups were subject to cycles of air/air under identical experimental conditions. A subset of male rats (8 controls, 8 CIH) had free access to water containing 1 mM Tempol (SOD-mimetic) at all times. Treatments were carried out for 8 hours a day for 9 days. Following treatment, normoxic ventilation was assessed by whole body plethysmography in sleeping animals. Baseline normoxic ventilation was increased in both male and female treated rats but this did not achieve statistical significance. However, ventilatory drive (V(T)/Ti) was significantly increased in male rats. Chronic treatment with Tempol abolished this effect. Conversely, CIH had no significant effect on VT/Ti in female rats. Our results indicate subtle effects of intermittent hypoxia on breathing in conscious behaving rats. We speculate the increased ventilatory drive following CIH represents a form a neural plasticity - a ROS dependent phenomenon - with sexual dimorphism. PMID:20217363

    This study was undertaken to evaluate the health effect of air pollution on pulmonary function and respiratory symptoms of Korean school children between 7 and 10 years of age during November 1995-January 1996. A standard respiratory symptom questionnaire was administered and spirometry was performed to examine pulmonary function of 121 children in an urban polluted area, Seoul, and of 119 children in non-polluted area, Sokcho, respectively. There was significant difference in the level of pulmonary function [forced expiratory volume in second (FEV{sub 1.0}) and forced vital capacity (FVC)] between exposed groups to polluted area and non-polluted area. Parental smoking was significantly related to respiratory symptoms of cough, phlegm, and the level of pulmonary function. The observed changes in FEV{sub 1.0} and FVC seemed to relate to home cooking fuel, not to respiratory symptoms. The additional longitudinal work that carefully monitors ambient and indoor air pollution and health effects data should be conducted to confirm these results.

  15. The global burden of chronic respiratory disease in adults.

    Burney, P; Jarvis, D; Perez-Padilla, R

    2015-01-01

    With an aging global population, chronic respiratory diseases are becoming a more prominent cause of death and disability. Age-standardised death rates from chronic obstructive pulmonary disease (COPD) are highest in low-income regions of the world, particularly South Asia and sub-Saharan Africa, although airflow obstruction is relatively uncommon in these areas. Airflow obstruction is, by contrast, more common in regions with a high prevalence of cigarette smoking. COPD mortality is much more closely related to the prevalence of a low forced vital capacity which is, in turn, associated with poverty. Mortality from asthma is less common than mortality from COPD, but it is also relatively more common in poorer areas, particularly Oceania, South and South-East Asia, the Middle East and Africa. Again this contrasts with the asthma prevalence among adults, which is highest in high-income regions. In high-income areas, mortality due to asthma, which is predominantly an adult problem, has fallen substantially in recent decades with the spread of new guidelines for treatment that emphasise the use of inhaled steroids to control the disease. Although mortality rates have been falling, the prevalence of atopy has been increasing between generations in Western Europe. Changes in the prevalence of wheeze among adults has been more varied and may have been influenced by the reduction in smoking and the increase in the use of inhaled steroids. PMID:25519785

    Exertional dyspnoea is among the dominant symptoms in patients with chronic heart failure and progresses relentlessly as the disease advances, leading to reduced ability to function and engage in activities of daily living. Effective management of this disabling symptom awaits a better understanding of its underlying physiology.Cardiovascular factors are believed to play a major role in dyspnoea in heart failure patients. However, despite pharmacological interventions, such as vasodilators or inotropes that improve central haemodynamics, patients with heart failure still complain of exertional dyspnoea. Clearly, dyspnoea is not determined by cardiac factors alone, but likely depends on complex, integrated cardio-pulmonary interactions.A growing body of evidence suggests that excessively increased ventilatory demand and abnormal "restrictive" constraints on tidal volume expansion with development of critical mechanical limitation of ventilation, contribute to exertional dyspnoea in heart failure. This article will offer new insights into the pathophysiological mechanisms of exertional dyspnoea in patients with chronic heart failure by exploring the potential role of the various constituents of the physiological response to exercise and particularly the role of abnormal ventilatory and respiratory mechanics responses to exercise in the perception of dyspnoea in patients with heart failure.

    After several cases of occupational asthma had been reported in a coffee processing factory in England, 197 coffee workers representing 80% of the production workforce were studied to determine the factors affecting the development of work related respiratory symptoms of wheeze, cough, and dyspnoea. Two computer administered questionnaires concerning the presence of respiratory symptoms and the occurrence of work related respiratory symptoms were used. Workers underwent skin prick testing to green coffee bean extract (GCB) and 11 common inhalant allergen extracts and bronchial provocation testing with methacholine. The presence of specific immunoglobulin E (IgE) antibodies to GCB and castor bean extract (CAB) were determined by a radioallergosorbent test (RAST). The prevalence of work related respiratory symptoms was 12.7%, bronchial hyperresponsiveness 30%, atopy 54%, positive GCB skin prick test 14.7%, positive GCB RAST 14%, and positive CAB RAST 14.7%. None of the workers was sensitised to fungi present in the factory and the numbers of certain species of fungi, despite being greater than may be found out of doors or in an uncontaminated indoor environment, were fewer than are generally associated with the presence of work related respiratory symptoms among agricultural workers. Storage mites were not isolated. Green coffee bean extract and CAB RAST were significantly correlated using the McNemar test but there was limited allergenic cross reactivity in RAST inhibition studies of the two extracts. The only factors that were significantly and independently associated with work related symptoms were CAB RAST and duration of employment. Bronchial hyperresponsiveness was not independently associated with work related respiratory symptoms. The significant independent associations of bronchial hyperresponsiveness included GCB RAST, duration of employment, and resting forced expiratory volume in one second. Exposure to CAB, a highly potent antigen, may be overriding

    A cross-sectional epidemiological study was conducted in an effort to investigate the effects of automobile exhaust on respiratory symptoms of school children in Kaohsiung, Taiwan. One school (Yang-Ming primary school) was located in the vicinity of 150 m from the highway and designated as a heavy-traffic area. The control school (Zhuang-Jing primary school) was situated in the same district but the distance of the school address to the freeway was 1500 m and designated as a low-traffic area. All of the primary school children in those schools were used in the study. In total, 3221 children were from the heavy-traffic school and 2969 from the low-traffic area. The respiratory health was assessed by an evaluation of the child's respiratory symptoms and illnesses using a parent-completed questionnaire. Data on traffic flow on the freeway were obtained from the Department of Transportation. Road traffic flows in front of the study schools were also measured with a portable counter. This study showed that a freeway surrounding a child's school may not be associated with an increased risk of respiratory symptoms. This may be due to insufficiently large contrasts in traffic pollution levels between these areas. PMID:12028826

    Full Text Available Background: This study aimed to assess the burden of household smoking habits on the occurrence of respiratory symptoms among young adolescents in Malaysia.Methodology: The impact of Secondhand Smoke (SHS exposures on the occurrence of respiratory symptoms was investigated on 234 adolescents (13-14 years old residing in two states in Malaysia. Adolescents completed a self-administered questionnaire adapted from Global Youth Tobacco survey that comprised of items on socio-demographic and SHS exposures. Respiratory symptoms were assessed using a standard questionnaire of International Study of Asthma and Allergies in Childhood. Hair samples were collected from each adolescent and were analyzed for nicotine via Gas Chromatography-Mass Spectrophotometry with nitrogen detection method.Result: The geometric mean of hair nicotine was 0.0184± 2.31 ng/mg. The prevalence of current, ever wheeze, nocturnal cough, exercised-induced wheeze and self-reported asthma were 7.69%, 14.1%, 11.5%, 20.5% and 13.7%, respectively. A significant association was found between household smoking status with exercise-induced wheeze (Adjusted Odds Ratio, AOR 1.06; 95%Confidence Interval, CI 0.42-2.66 and nocturnal cough (AOR 14.2; 95%CI 1.60-125. Reported ever wheeze was linked to reported SHS exposure in family’s vehicle (AOR 3.27; 95%CI 1.15-9.34. The risk of exercise-induced wheeze was related with postnatal SHS exposure (AOR 2.69; 95%CI 1.13-6.43.Conclusion: Respiratory symptoms were mostly affected by household smoking habits. Thus, in an attempt to reduce the repercussion of SHS exposure among younger adolescents, effort should be emphasized in encouraging parents to move from indoor to outdoor smoking far from the vicinity of children.Keywords: Passive smoking, Household smoking habits, Youth, Respiratory health, Hair nicotine

    Many recent studies suggest that urban air pollution, especially thoracic particles (PM{sub 10}), are associated with increased respiratory, mortality and morbidity at lower levels than what has previously been known. During the Finnish winter, the dust formed from asphalt ware by studded auto tyres, street sanding and combustion processes is accumulated on the snow. In the spring, when the snow melts from the streets, part of this dust is resuspended by traffic and wind. This creates spring dust episodes, during which TSP and PM{sub 10} levels exceed air quality guidelines in most Finnish cities. The mechanisms through which PM{sub 10} produces its health effects are largely unknown. It has been suggested that the number of particles, especially that of very small particles in the nanometer range, would be as important as the mass or the chemical composition of the particles. In most previous studies, the particles measured have mostly composed of combustion products. There are only sparse data on the size distribution of particles in the Finnish spring dust episode and no studies on it`s possible health effects. The aim of the PEACE project was to develop a common protocol for research on the short-term relationship between respiratory health and changes in air pollution levels. The present report describes the design and preliminary results of Finnish field work of the PEACE study that was carried out in Kuopio, Eastern Finland. (author)

    Full Text Available Objective: To compare patients with panic disorder with agoraphobia treated with cognitive-behavioural therapy (CBT associated with the medication with patients treated only with medication and verify the behaviour of the cardio-respiratory symptoms of both groups. Methods: Randomized sample in the Psychiatry Institute of the Federal University of Rio de Janeiro, divided in two groups of 25 participants each. Group 1 undertook 10 weekly sessions of CBT with one hour of duration each together with medication. Group 2, Control, were administered medication that only consisted of tricyclic anti-depressants and selective inhibitors of the re-uptake of serotonin. Evaluation instruments were applied at the beginning and to the end of the interventions. Results: According to the applied scales, group 1 showed statistically more significant results than group 2, with: reduction of panic attacks, cardio-respiratory symptoms, anticipatory anxiety, agoraphobia avoidance and fear of bodily sensations. Conclusion: Exposures (in vivo and interoceptive, especially for induction symptom exercises and relaxation, were considered essential to prepare patients with panic disorder to handle future cardio-respiratory symptoms and panic attacks with agoraphobia.

    Florida red tides are naturally occurring blooms of the marine dinoflagellate, Karenia brevis. K. brevis produces natural toxins called brevetoxins. Brevetoxins become part of the marine aerosol as the fragile, unarmored cells are broken up by wave action. Inhalation of the aerosolized toxin results in upper and lower airway irritation. Symptoms of brevetoxin inhalation include: eye, nose, and throat irritation, coughing, wheezing, chest tightness, and shortness of breath. Asthmatics appear to be more sensitive to the effects of inhaled brevetoxin. This study examined data from 97 asthmatics exposed at the beach for 1 hour during K. brevis blooms, and on separate occasions when no bloom was present. In conjunction with extensive environmental monitoring, participants were evaluated utilizing questionnaires and pulmonary function testing before and after a 1-hour beach walk. A modified Likert scale was incorporated into the questionnaire to create respiratory symptom intensity scores for each individual pre- and post-beach walk. Exposure to Florida red tide significantly increased the reported intensity of respiratory symptoms; no significant changes were seen during an unexposed period. This is the first study to examine the intensity of reported respiratory symptoms in asthmatics after a 1-hour exposure to Florida red tide. PMID:17885863

    OBJECTIVE Respiratory abnormalities are well documented in acute spinal cord injury; however, the literature available for respiratory dysfunction in chronic compressive myelopathy (CCM) is limited. Respiratory dysfunction in CCM is often subtle and subclinical. The authors studied the pattern of respiratory dysfunction in patients with chronic cord compression by using spirometry, and the clinical and surgical implications of this dysfunction. In this study they also attempted to address the postoperative respiratory function in these patients. METHODS A prospective study was done in 30 patients in whom cervical CCM due to either cervical spondylosis or ossification of the posterior longitudinal ligament (OPLL) was diagnosed. Thirty age-matched healthy volunteers were recruited as controls. None of the patients included in the study had any symptoms or signs of respiratory dysfunction. After clinical and radiological diagnosis, all patients underwent pulmonary function tests (PFTs) performed using a standardized Spirometry Kit Micro before and after surgery. The data were analyzed using Statistical Software SPSS version 13.0. Comparison between the 2 groups was done using the Student t-test. The Pearson correlation coefficient was used for PFT results and Nurick classification scores. A p value Cervical spondylotic myelopathy (prolapsed intervertebral disc) was the predominant cause of compression (n = 21, 70%) followed by OPLL (n = 9, 30%). The average patient age was 45.06 years. Degenerative cervical spine disease has a relatively younger onset in the Indian population. The majority of the patients (n = 28, 93.3%) had compression at or above the C-5 level. Ten patients (33.3%) underwent an anterior approach and discectomy, 11 patients (36.7%) underwent decompressive laminectomy, and the remaining 9 underwent either corpectomy with fusion or laminoplasty. The mean preoperative forced vital capacity (FVC) (65%) of the patients was significantly lower than that of

    Objective: To determine prevalence of depression in chronic respiratory disorders in a tertiary rural hospital of Central India. Various studies done in past have shown that prevalence of depression in diabetes and hypertension is around 40%-57%. Few studies have been done to screen depression in chronic respiratory disorders. This study was conducted in a tertiary rural hospital of Central India to find out prevalence of depression in indoor patients suffering from chronic respiratory disorders. Methods: Total 68 patients were evaluated for depression. Patients suffering from chronic respiratory disorders (total duration of illness >3 months) were evaluated using Prime MD Questionnaire. Patients suffering from diabetes, heart diseases, stroke, having past history of psychiatric illness, drug abusers, having lack of social support and suffering from chronic upper respiratory tract infections were excluded from this study. Questionnaire was asked when treatment for acute phase of illness is over. Results: Out of 68 patients evaluated, 36 (53%) were found out to be suffering from depression. Female gender (80%) was more prone to depression, inspite of the fact that all alcoholics were male. 39% of all chronic obstructive pulmonary disease (COPD) patients were suffering from depression in comparison to 65% for pulmonary tuberculosis and 44% for other chronic respiratory illness. 54% of patients suffering from depression are 60 yrs of age, suggesting that age has no relation with depression. No association was seen between alcoholism and depression. Conclusion: Prevalence of depression in patients of chronic respiratory illness is very high, like in cases of diabetes and hypertension. Further community and hospital based studies are needed to find out exact prevalence of depression in chronic respiratory illnesses.

    In British Columbia, some tree planting operations require workers to fertilize planted seedlings with polymer-coated nitrogen, phosphorus, and potassium (NPK) fertilizers. This study examined respiratory and dermal health associated with fertilizer exposure among tree planters. We interviewed 223 tree planters using an adapted version of the American Thoracic Society questionnaire supplemented with questions on dermal health. Subjects were grouped by categories of increasing duration of exposure, with workers who had not worked with fertilizer as a reference group. The relationship between exposure and reported work-related symptoms was analyzed using logistic regression, adjusting for age, cumulative tobacco cigarettes smoked, marijuana smoking status, sex, and exposure to abrasive spruce needles. An elevated odds ratio was seen for work-related cough, phlegm, nasal symptoms, nosebleed, and skin rash in the highest exposure group (>37 days of fertilizer use in the past 2 years) but was significant only for phlegm (odds ratio = 3.59, 95% confidence interval = 1.10-11.70). Trends of increasing odds ratios with increasing exposure were seen for cough, phlegm, nasal symptoms, and skin rash. The results suggest a weak association between respiratory and dermal irritation and work with fertilizer. Results highlight the need for further exposure monitoring within the tree planting industry, and larger studies to investigate the relationship between work with fertilizer and respiratory and dermal health symptoms.

Methods A total of 278 eligible patients (244 men and 34 women, aged 50–75 years with COPD diagnosed within the past four years, were referred by respiratory physicians, while 340 controls (272 men and 68 women were recruited from the community. All participants underwent spirometric measurements of respiratory function. Information on demographics, lifestyle characteristics and habitual food consumption was obtained using a structured questionnaire. Results Total soy consumption was positively correlated with observed lung function measures. The mean soy intake was significantly higher among controls (59.98, SD 50.23 g/day than cases (44.84, SD 28.5 g/day. A significant reduction in COPD risk was evident for highest versus lowest quartile of daily intake of total soybean products, with adjusted odds ratio (OR 0.392, 95% CI 0.194–0.793, p for trend 0.001. Similar decreases in COPD risk were associated with frequent and higher intake of soy foods such as tofu and bean sprouts, whereas respiratory symptoms were inversely associated with high consumption of soy foods, especially for breathlessness (OR 0.989, 95% CI 0.982–0.996. Conclusion Increasing soy consumption was associated with a decreased risk of COPD and breathlessness.

  10. Respiratory symptoms in rheumatoid arthritis. Relation between high resolution CT findings and functional impairment

    International Nuclear Information System (INIS)

    The objectives of this study were to analyze the high resolution computed tomography (HRCT) findings in rheumatoid arthritis (RA) patients with respiratory symptoms and to evaluate the relation between the extent of HRCT findings and functional impairment as assessed by spirometry. HRCT examination of the thorax and pulmonary function tests (PFTs) were performed in 34 RA patients with respiratory symptoms. Patients with smoking history or with emphysema evident on HRCT were excluded from the study. CT findings were assessed for the presence and pattern of abnormalities. Extent was scored based on the number of pulmonary segments involved. PFTs included forced expiratory flows (FEFs) and forced vital capacity (FVC). Bronchial wall thickening was detected in 29 of 34 RA patients (85%), small nodules in 24 patients (71%), and bronchial dilatation in 21 patients (62%). The extent of bronchial wall thickening correlated with FEF25-75, FEF75, and FEF50 (p<0.0001, respectively) (Spearman's rank correlation). Extent of small nodules correlated with FEF25-75, FEF50, and FEF25 (p<0.01, respectively). Stepwise regression analysis showed independent correlations of bronchial wall thickening with decreases in FEF25-75 and FEF75 (p<0.0001, both). Bronchial dilatation was also independently associated with a decrease in FVC (p<0.05). The most common HRCT findings in RA patients with respiratory symptoms are bronchial wall thickening and small nodules, and the extent of these findings correlates significantly with functional impairment.

    Full Text Available OBJECTIVE: Recent work has suggested that within-breath respiratory impedance measurements performed using the forced oscillation technique may help to noninvasively evaluate respiratory mechanics. We investigated the influence of airway obstruction on the within-breath forced oscillation technique in smokers and chronic obstructive pulmonary disease patients and evaluated the contribution of this analysis to the diagnosis of chronic obstructive pulmonary disease. METHODS: Twenty healthy individuals and 20 smokers were assessed. The study also included 74 patients with stable chronic obstructive pulmonary disease. We evaluated the mean respiratory impedance (Zm as well as values for the inspiration (Zi and expiration cycles (Ze at the beginning of inspiration (Zbi and expiration (Zbe, respectively. The peak-to-peak impedance (Zpp=Zbe-Zbi and the respiratory cycle dependence (ΔZrs=Ze-Zi were also analyzed. The diagnostic utility was evaluated by investigating the sensitivity, the specificity and the area under the receiver operating characteristic curve. ClinicalTrials.gov: NCT01888705. RESULTS: Airway obstruction increased the within-breath respiratory impedance parameters that were significantly correlated with the spirometric indices of airway obstruction (R=−0.65, p90%. CONCLUSIONS: We conclude the following: (1 chronic obstructive pulmonary disease introduces higher respiratory cycle dependence, (2 this increase is proportional to airway obstruction, and (3 the within-breath forced oscillation technique may provide novel parameters that facilitate the diagnosis of respiratory abnormalities in chronic obstructive pulmonary disease.

    Tracheal diverticulum (TD) defined as a typical benign out-pouching of the tracheal wall due to structural weakness, congenital or acquired in origin, resulting in paratracheal air cysts. It is rarely diagnosed in clinical practice with only limited reports in the literature. Most cases found incidentally in the postmortem examination and located on the right side. Uncomplicated TDs are usually asymptomatic and when symptoms have occurred, they usually present with non-specific symptoms like pharyngeal discomfort, cough, dyspnea, and recurrent respiratory infection due to either the compression of adjacent organs or secondary bacterial infection. Imaging techniques like thoraco-cervical multi-slice spiral computed tomography (CT) and fiber-optic bronchoscopy are important diagnostic tools for this entity. Asymptomatic TDs usually require no treatment and managed conservatively while surgical excision is indicated in cases of compression of adjacent organs and recurrent infections. Here we report a case of tracheal diverticulum on the left side, which was diagnosed as part of a work-up for chronic cough and recurrent chest infection in a 40 year old female who was already on bronchodilator without any relief. Diagnosis of TD was based on findings of computed tomography, revealing small bud like projection on left para tracheal region and further confirmed by fiber-optic bronchoscopy while the barium contrast study showed no esophageal communication. She was managed conservatively and referred for surgical excision. PMID:27266290

    Ozone-induced respiratory symptoms are known to be functions of concentration, minute ventilation, and duration of exposure. The purposes of this study were to identify an exposure-response model for symptoms, to determine whether response was related to age, and to assess the relationships between symptom and lung function responses to ozone. Four hundred and eighty-five healthy male volunteers (ages 18 - 35 yrs) were exposed to one of six ozone concentrations at one of three activity levels for 2 hours. Symptoms and forced expiratory volume in one second (FEV1) were assessed at the end of 1 and 2 hours. The exposure and response data were fitted by a non-linear exposure-response model previously found to describe FEV1 response. The proportion of individuals experiencing moderate or severe cough, shortness of breath, and pain on deep inspiration were accurately described as functions of concentration, minute ventilation, and time. Response was inversely related to age for shortness of breath (p = 0.0001), pain on deep inspiration (p = 0.0002), and cough (p = 0.0013). Controlling for exposure differences, symptom responses were significantly but weakly (correlation coefficient 0.30 - 0.41) related to the FEV1 response. In conclusion, the exposure-response model did accurately predict symptoms, response was inversely related to age. (au)

    Respiratory symptoms and ventilatory capacity were studied in 63 flour processing male bakery workers in Umtata, Transkei, Southern Africa. The controls were from a bottling plant in the same city. Both groups were black Africans from the Xhosa-speaking population. The studied population was nonsmoking and no significant difference was noted in age, race, sex, or height between the groups. The exposed workers had significantly lower forced expiratory indices than the control group. Mean percent predicted values of forced expiratory volume in one second (FEV1), forced expiratory ratio (FEV1/FVC x 100), forced mid-expiratory flow between 25% and 75% of FVC (FMF), forced expiratory flow between the first 200 ml and 1,200 ml of FVC (FEF 200-1,200), and peak expiratory flow rate (PEF) were, respectively, 11.2%, 20.0%, 31.0%, 27.4%, and 36.1% lower in the exposed group compared with the controls. The prevalence of forced expiratory ratio less than 70% in the exposed group was 37% while in the controls it was 8%. The prevalence of PEF rate less than 5 1/s in the exposed group was 32% while in the controls it was 11%. The exposed workers reported a significantly higher prevalence of respiratory symptoms compared to the controls. The prevalence of nasal symptoms, phlegm, and cough in the exposed workers was 53.9%, 30.1%, and 25.4%, respectively. The present study demonstrated that exposure to flour dust in flour processing workers in the baking industry is associated with significantly lower pulmonary functions and a higher prevalence of respiratory symptoms, and that these workers show signs of airway obstruction, compared to workers not exposed to flour.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:7747742

    Full Text Available Abstract Background Gastrointestinal (GI, respiratory and dermal symptoms are common and cause substantial morbidity, although the information on their exact incidence and comparative burden is limited. The aim of this study was to describe the epidemiology and rate these three major symptom complexes in order to improve our understanding of the health burden imposed by these symptoms. Methods We used data from a community based randomised control trial conducted from June 2007 to August 2008 among 277 South Australian families consuming rainwater. Using weekly health diaries, we prospectively collected information on GI (diarrhoea or vomiting, respiratory (sore throat, runny nose or cough and dermal (rash, generalised itch or dermal infection symptoms, as well as on relevant GP visits, time off work and/or hospitalisation due to these symptoms. Data were analysed using generalized estimating equations approach taking into account the variable number of weeks of follow-up of each individual and within-family clustering of responses. Results Over one year, at least one episode of GI symptoms was reported by 54% of participants (95% CI 50%-58%, at least one respiratory episode by 91% (95% CI 88%-93% and at least one episode of dermal symptoms by 27% (95% CI 24%-30%. The average number of weeks per year during which respiratory symptoms occurred was four times greater than for GI or dermal symptoms (4.9, 1.2 and 1.2 weeks, respectively, p Conclusions This first comparative study of three different symptom complexes showed that although respiratory symptoms are most common, GI symptoms cause a greater per episode burden on healthcare resources. Measuring and comparing the community based burden of these symptom complexes will assist evidence-based allocation of resources.

    Full Text Available OBJECTIVES: The objectives of this study were to verify the degree of anxiety, respiratory distress, and health-related quality of life in a group of asthmatic patients who have experienced previous panic attacks. Additionally, we evaluated if a respiratory physiotherapy program (breathing retraining improved both asthma and panic disorder symptoms, resulting in an improvement in the health-related quality of life of asthmatics. METHODS: Asthmatic individuals were assigned to a chest physiotherapy group that included a breathing retraining program held once a week for three months or a paired control group that included a Subtle Touch program. All patients were assessed using the Diagnostic and Statistical Manual of Mental Disorders IV, the Sheehan Anxiety Scale, the Quality of Life Questionnaire, and spirometry parameter measurements. RESULTS: Both groups had high marks for panic disorder and agoraphobia, which limited their quality of life. The Breathing Retraining Group program improved the clinical control of asthma, reduced panic symptoms and agoraphobia, decreased patient scores on the Sheehan Anxiety Scale, and improved their quality of life. Spirometry parameters were unchanged. CONCLUSION: Breathing retraining improves the clinical control of asthma and anxiety symptoms and the health-related quality of life in asthmatic patients.

    Full Text Available The purpose of this study was to determine the presence of recurrent airway obstruction (RAO through bronchoalveolar lavage (BAL in a group of twenty Colombian native horses with respiratory symptoms. Each animal underwent a clinical examination in order to corroborate the respiratory disturbance and later perform the BAL. The results obtained showed that 65% of the animals under study tested positive for RAO, based on the clinical and BAL results, and that, among the total number of animals that tested positive, 61.5% suffered a severe form of such condition. We also found an association between the number of neutrophils and the color of the BAL fluid, and an inverse relationship between cell cytology of macrophages and neutrophils. It is concluded that the Colombian native horse, like other horse breeds, suffers from RAO, sometimes severely, related to predisposing factors such as accommodation and stabling.

  4. Respiratory and ocular symptoms among employees of a hotel indoor waterpark resort--Ohio, 2007.

    Science.gov (United States)

    2009-02-01

    During January--March 2007, the Warren County Combined Health District (WCCHD) received 665 reports of respiratory and eye irritation from patrons and lifeguards at a hotel indoor waterpark resort in Ohio. Tests revealed normal water chemistry and air chlorine concentrations, and exposure to airborne trichloramine in the waterpark was suspected as the cause of the symptoms. Because of the number of symptom reports and WCCHD's limited ability to measure trichloramine, the district requested an investigation by CDC's National Institute for Occupational Safety and Health (NIOSH). This report describes the results of that investigation, which revealed that trichloramine concentrations in the waterpark ranged from below the limit of detection to 1.06 mg/m3, and some concentrations were at levels that have been reported to cause irritation symptoms (>/=0.5 mg/m3). Lifeguards reported significantly more work-related symptoms (e.g., cough, wheezing, shortness of breath, chest tightness, and eye irritation) than unexposed hotel employees. Lifeguards also reported significantly more eye irritation and cough on days when hotel occupancy was high versus low. Insufficient air movement and distribution likely led to accumulation of trichloramine and exacerbation of symptoms. Based on recommendations to increase air movement and distribution at pool deck level, hotel management modified the ventilation system extensively, and subsequently no new cases were reported to WCCHD. The results of this investigation emphasize the importance of appropriate design and monitoring of ventilation and water systems in preventing illness in indoor waterparks. PMID:19194369

    1983-02-01

    In four groups of individually-matched subjects (nonsmoking grain workers, smoking grain workers, nonsmoking community controls, and smoking community controls) we measured pulmonary function variables from the spirogram, from the maximal expiratory flow-volume curve breathing air and helium, and from the single breath nitrogen test as well as symptom prevalences from a questionnaire in order to assess the relative effects of smoking and occupational exposure to grain dust in Saskatchewan country grain elevators. There were similar increased prevalences of respiratory symptoms and reductions in pulmonary function associated with either grain dust exposure or smoking, but the effects of smoking were slightly more pronounced. The combined effects of grain dust and smoking on lung function appeared to be additive except in the least exposed workers (five years or less) where a synergistic effect was observed in tests of peripheral airways dysfunction.

    Background: Despite widely available data about childhood asthma, there are limited data about the prevalence of asthma among young adults in Iran. The aim of this study was to determine the prevalence of asthma and respiratory symptoms among medical students in the city of Sari in Northern Iran. Materials and Methods: The prevalence of asthma and respiratory symptoms was studied using a standard questionnaire. Based on the information obtained from the questionnaires, the study participants were divided into two groups of asthmatics and non-asthmatics. Pulmonary function tests including forced expiratory volume in one second (FEV1) and forced vital capacity (FVC) before, and after salbutamol inhalation were measured in all subjects with asthma and approximately 10% of those without asthma. Results: A total of 1,011 subjects (374 males, 637 females) participated in this study. Asthma was found in 3.5% of the subjects (3.2% males and 3.6% females). The 12-month prevalence of wheezing, coughing at rest, coughing at night, breathlessness at rest, exercise-induced wheezing, and exercise-induced coughing in the entire study population was 11.1%, 12.4%, 13.4%, 13.3%, 17.7%, and 16.7%, respectively. The prevalence of all asthma-related symptoms was significantly higher among asthmatics compared to non-asthmatics. Moreover, asthmatic subjects showed lower FEV1 and FVC values compared to nonasthmatic subjects (P<0.001). Smoking and family history of asthma were statistically significant risk factors for developing asthma. Conclusion: The high prevalence of asthma related symptoms in the present study strongly suggests that asthma is under diagnosed and under treated among participants.

    Full Text Available Abstract Background Despite optimal pharmacological therapy and pulmonary rehabilitation, patients with COPD continue to be breathless. There is a need to develop additional strategies to alleviate symptoms. Learning to sing requires control of breathing and posture and might have benefits that translate into daily life. Methods To test this hypothesis we performed a randomised controlled trial, comparing a six week course of twice weekly singing classes to usual care, in 28 COPD patients. The experience of singing was assessed in a qualitative fashion, through interviews with a psychologist. In addition, we surveyed patients with chronic respiratory conditions who participated in a series of open singing workshops. Results In the RCT, the physical component score of the SF36 improved in the singers (n = 15 compared to the controls (n = 13; +7.5(14.6 vs. -3.8(8.4 p = 0.02. Singers also had a significant fall in HAD anxiety score; -1.1(2.7 vs. +0.8(1.7 p = 0.03. Singing did not improve single breath counting, breath hold time or shuttle walk distance. In the qualitative element, 8 patients from the singing group were interviewed. Positive effects on physical sensation, general well-being, community/social support and achievement/efficacy emerged as common themes. 150 participants in open workshops completed a questionnaire. 96% rated the workshops as "very enjoyable" and 98% thought the workshop had taught them something about breathing in a different way. 81% of attendees felt a "marked physical difference" after the workshop. Conclusion Singing classes can improve quality of life measures and anxiety and are viewed as a very positive experience by patients with respiratory disease; no adverse consequences of participation were observed.

    A cross-sectional survey was conducted to characterize the indoor air quality (IAQ) in schools and its relationship with children's respiratory symptoms. Concentrations of volatile organic compounds (VOC), aldehydes, PM2.5, PM10, carbon dioxide, bacteria and fungi were assessed in 73 classrooms from 20 public primary schools located in Porto, Portugal. Children who attended the selected classrooms (n = 1134) were evaluated by a standardised health questionnaire completed by the legal guardians; spirometry and exhaled nitric oxide tests. The results indicated that no classrooms presented individual VOC pollutant concentrations higher than the WHO IAQ guidelines or by INDEX recommendations; while PM2.5, PM10 and bacteria levels exceeded the WHO air quality guidelines or national limit values. High levels of total VOC, acetaldehyde, PM2.5 and PM10 were associated with higher odds of wheezing in children. Thus, indoor air pollutants, some even at low exposure levels, were related with the development of respiratory symptoms. The results pointed out that it is crucial to take into account the unique characteristics of the public primary schools, to develop appropriate control strategies in order to reduce the exposure to indoor air pollutants and, therefore, to minimize the adverse health effects.

    Surveillance using admissions to hospital, while being useful, is a poor indicator of the real incidence of disease encountered by travelers. An alternative is self-reported illness among those who attended at a pretravel clinic prior to their travels. Estimates of incidence and risk factors were determined for attendees at a travel clinic in Scotland using a questionnaire. Analysis for risk factors was carried out for those travelers visiting countries in Africa, Asia, or South and Central America, who had traveled for 1 week or more and had returned between 1997 and 2001 (N= 4,856). Multivariate logistic regression was used to test the hypotheses that time abroad and age-group would be significant for both respiratory and diarrheal symptoms regardless of which of the three geographical areas are visited. From 2006 returned questionnaires (response rate = 41.3%), diarrhea and respiratory symptoms were reported by 44.2 and 16.8% of respondents, respectively; the incidence was significantly greater among travelers to Asia for both diarrheal (55.5%) and respiratory (23.7%) symptoms than among travelers to Africa (36.6 and 12.2%, respectively) or South and Central America (39.5 and 16.2%, respectively). For diarrhea, age was a highly significant risk factor for travelers to Asia, South and Central America, and Africa. Being a self-organized tourist/backpacker, traveling to Asia was associated with increased risk, while for Africa and South and Central America visiting family or friends was associated with a lower risk. For travelers to Asia, traveling to the Indian subcontinent was significantly associated with increased risk. The majority of travelers had an adverse event while traveling abroad, with diarrhea and respiratory conditions being especially common despite attending a travel clinic for advice prior to departure. However, the limitations of this surveillance-based strategy have highlighted the requirement for more research to understand more fully the

    Background Category Ⅲ chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is a common syndrome of unclear etiology with significant impact on quality of life. Because the outcomes of multiple therapies for CP/CPPS have been far from approving, the possible psychological factors have been considered to play an important role in CP/CPPS.Based on this, we investigated the role of antidepressant drug (fluoxetine) in men with refractory CP/CPPS.Methods In this study, 42 men diagnosed with refractory CP/CPPS without response to standard therapy (include multiple antibiotic courses and a-blockers) were referred for fluoxetine therapy. All patients received fluoxetine (20 mg/d) for three months and were clinically evaluated before (baseline), and after 4, 8 and 12 weeks of therapy. The evaluation included a National Institutes of Health-chronic prostatitis symptom index (NIH-CPSI) and a Beck depression inventory (BDI) questionnaire. Moreover, the subjective global assessment (SGA) was assessed at the 4th, 8th and 12th week of therapy.Results Significant decreases were observed for total NIH-CPSI (28.55 to 9.29), NIH-CPSI pain (14.69 to 5.19),NIH-CPSI urinary (4.95 to 1.88 ), NIH-CPSI quality of life (8.83 to 2.20), and BDI (34.67 to 13.95) scores compared with baseline, all P values <0.05. Twenty-nine (69.05%) reported marked improvement on the subjective global assessment and 33 (78.57%) had a greater than 50% decrease in NIH-CPSI at the end of therapy (12th week). At the same time, the Pearson correlation coefficient analysis demonstrated a positive correlation between BDI score and each CPSI score. No adverse events were reported in this study.Conclusions Fluoxetine appears to be a safe and effective treatment in improving symptoms in, and the quality of life of, men with difficult CP/CPPS. Moreover, amelioration of difficult CP/CPPS-related symptoms could be related to a decrease in depressive symptoms.

    Full Text Available Abstract Background We examined the association between single nucleotide polymorphisms (SNPs in loci encoding surfactant protein A (SFTPA and risk of wheeze and persistent cough during the first year of life among a cohort of infants at risk for developing asthma. Methods Between September 1996 and December 1998, mothers of newborn infants were invited to participate if they had an older child with clinician-diagnosed asthma. Each mother was given a standardized questionnaire within 4 months of her infant's birth. Infant respiratory symptoms were collected during quarterly telephone interviews at 6, 9 and 12 months of age. Due to the association of SFTPA polymorphisms and race/ethnicity, analyses were restricted to 221 white infants for whom whole blood and respiratory data were available. Ordered logistic regression models were used to examine the association between respiratory symptom frequency and SFTPA haplotypes. Results The 6A allele haplotype of SFTPA1, with an estimated frequency of 6% among our study infants, was associated with an increased risk of persistent cough (OR 3.69, 95% CI 1.71, 7.98 and wheeze (OR 4.72, 95% CI 2.20, 10.11. The 6A/1A haplotype of SFTPA, found among approximately 5% of the infants, was associated with an increased risk of persistent cough (OR 3.20, 95% CI 1.39, 7.36 and wheeze (OR 3.25, 95% CI 1.43, 7.37. Conclusion Polymorphisms within SFTPA loci may be associated with wheeze and persistent cough in white infants at risk for asthma. These associations require replication and exploration in other ethnic/racial groups.

    Full Text Available Abstract Background Symptom-based questionnaires can be a cost effective tool enabling identification and diagnosis of patients with respiratory illnesses in resource limited setting. This study aimed to determine the correlation of respiratory symptoms and spirometric lung patterns and validity of ATS respiratory questionnaire in a rural community setting. Methods This cross sectional survey was conducted between January – March 2009 on a sample of 200 adults selected from two villages of district Khairpur, Sindh, Pakistan. A modified version of the American thoracic society division of lung disease questionnaire was used to record the presence of respiratory symptoms. Predicted lung volumes i.e. forced vital capacity (FVC, forced expiratory volume in one second (FEV1 and their ratio (FEV1/FVC were recorded using portable spirometer. Results In the study sample there were 91 (45.5% males and 109 (54.5% females with overall mean age of 34 years (±11.69. Predominant respiratory symptom was phlegm (19% followed by cough (17.5%, wheeze (14% and dyspnea (10.5%. Prevalence of physician diagnosed and self-reported asthma was 5.5% and 9.5% respectively. Frequency of obstructive pattern on spirometry was 28.72% and that of restrictive pattern was 19.68%. After adjustment for age, gender, socioeconomic status, spoken dialect, education, smoking status, height, weight and arsenic in drinking water, FVC was significantly reduced for phlegm (OR 3.01; 95% CI: 1.14 – 7.94, wheeze (OR 7.22; 95% CI: 2.52 – 20.67 and shortness of breath (OR 4.91; 95% CI: 1.57 – 15.36; and FEV1 was significantly reduced for cough (OR 2.69; 95% CI: 1.12 – 6.43, phlegm (OR 3.01; 95% CI: 1.26 – 7.16 and wheeze (OR 10.77; 95% CI: 3.45 – 33.6.

    To effectively track the growth of influenza, we piloted an online system to monitor influenza-like illness (ILI) in the community in one district of Hong Kong. Four syndromic markers, namely fever, respiratory symptoms, fever with respiratory symptoms, fever and/or respiratory symptoms, either of the individual or of the household, were collected during the study period from June 2012 to October 2013. A total of 132 residents of Tuen Mun District reported syndromic markers at the individual and household levels on a weekly basis. Temporal patterns of these markers were compared with data derived from laboratory surveillance by dynamic linear regression. Household respiratory symptoms were found to be an effective syndromic marker, pre-dating overall laboratory virus surveillance results on influenza diseases in two influenza seasons by 3-4 weeks. To conclude, respiratory symptoms can be a good marker predicting the onset of the influenza season in the community, and is particularly useful with regard to data from households, even if the sample size may not be a large one.

    Full Text Available Introduction The role of cross-reactive carbohydrate determinants (CCDs in diagnostics of occupational allergy remains unclarified and its clinical relevance is still questioned. The aim of the study was to assess the frequency of positive response to CCDs in the subjects with suspected occupational allergy and the relationship between other diagnostic test results and final diagnosis. Material and methods The study group included 201 patients. They underwent clinical examination, skin prick test (SPT to common and occupational allergens, specific serum immunoglobulin (sIgE determinations, spirometry and specific inhalation challenge test. Moreover, sIgE to CCDs from bromelain was assessed in all subjects. Results Occupational respiratory allergy was recognized in 64.3% of CCD-positive and 52.4% of CCD-negative patients. Positive SPT results to common and occupational allergens were found in 64.3% and 35.7% of CCD-positive subjects, respectively. In all subjects with CCDs, the sIgE to grass pollens as well as to occupational allergens were detected. The total IgE level > 100 kU/l was significantly associated with the presence of sIgE to CCDs. Conclusions sIgE to CCDs were found in 7% of subjects suspected to suffer from occupational respiratory allergy. The presence of CCDs is not significantly associated with occupational respiratory allergy. It is also not more frequent in subjects reporting work-related respiratory symptoms in whom occupational allergy was not confirmed. The elevated total IgE level was related with CCD positivity. In patients with suspected occupational allergy, the presence of sIgE to CCDs in serum did not indicate the irrelevance of positive sIgE to occupational allergens.

    2007-09-01

    Full Text Available Abstract Background Inspiratory occlusion evoked cortical potentials (the respiratory related-evoked potentials, RREPs bear witness of the processing of changes in respiratory mechanics by the brain. Their impairment in children having suffered near-fatal asthma supports the hypothesis that relates asthma severity with the ability of the patients to perceive respiratory changes. It is not known whether or not chronic respiratory defects are associated with an alteration in brain processing of inspiratory loads. The aim of the present study was to compare the presence, the latencies and the amplitudes of the P1, N1, P2, and N2 components of the RREPs in children with chronic lung or neuromuscular disease. Methods RREPs were recorded in patients with stable asthma (n = 21, cystic fibrosis (n = 32, and neuromuscular disease (n = 16 and in healthy controls (n = 11. Results The 4 RREP components were significantly less frequently observed in the 3 groups of patients than in the controls. Within the patient groups, the N1 and the P2 components were significantly less frequently observed in the patients with asthma (16/21 for both components and cystic fibrosis (20/32 and 14/32 than in the patients with neuromuscular disease (15/16 and 16/16. When present, the latencies and amplitudes of the 4 components were similar in the patients and controls. Conclusion Chronic ventilatory defects in children are associated with an impaired cortical processing of afferent respiratory signals.

    Chronic obstructive pulmonary disease and asthma impose a substantial burden of disease. This narrative review focuses on potential population-wide interventions that are likely to have an impact on these diseases. The developmental origins of adult disease commence in utero, with maternal nutrition being of particular interest. However, to date, trials of maternal allergen avoidance, dietary supplementation or probiotics have not shown consistent protective effects against asthma. Poor indoor air quality, especially from biomass fuels as well as second-hand tobacco smoke, is a well-recognised risk factor for chronic respiratory diseases. This can be modified by cleaner fuels, cooking stoves or heaters, and improved ventilation. Although allergens are a risk factor for childhood asthma, the results of interventions to reduce exposures have been disappointing. Traffic-related air pollution is associated with an increased incidence of asthma in children. Primary prevention of the adverse effects of air pollution has focused on the development of ambient air quality guidelines, but enforcement remains a challenge in many countries. Occupational asthma may be induced by sensitisers or irritants in the workplace. Prevention involves eliminating the agent or reducing exposure as far as possible, which is more effective than respiratory protective equipment. Smoking cessation remains a key proven preventive strategy for chronic respiratory diseases. There is now an international framework for tobacco control, and recent innovations include plain packaging of tobacco. Chronic respiratory diseases can be substantially prevented by the above population-wide interventions. PMID:26260817

    The literature lacks reports on the role played by the Environmental domain of quality of life (QoL) in care for patients with chronic respiratory diseases. Such information has a high potential for implementation in modern medicine based on a 'tailor-made' holistic healthcare model. The purpose of this study was to determine the components that shape the Environmental domain of QoL in patients with chronic respiratory diseases. The study group consisted of 305 adult patients (median age 65 years) with at least one chronic respiratory disease. The greatest contribution to a high value of QoL in the Environmental domain among patients with chronic respiratory diseases was made by the coexistence of high QoL levels in other domains and in satisfaction with QoL. Programs for preventing a decline in QoL in the Environmental domain should include patients with low scores for the above variables as well as those with a low level of education, those who have not shown an improvement in their psychological well-being in the past 12 months, those with a low level of positive mental attitudes or healthy eating habits, a low Camberwell index, and low levels of overall pro-health behavior.

    2008-01-01

    This paper is a review of current approaches on pulmonary rehabilitation (PR) in chronic pulmonary diseases. Pulmonary rehabilitation is the most accepted method of non-pharmacological treatment in patients with chronic obstructive pulmonary disease (COPD), bronchial asthma, bronchiectasis, cystic fibrosis, interstitial lung disease, neuromuscular degenerative disease and post-tuberculosis lung sequelae. Throughout its components, especially oxygen therapy, it is the most important intervention in chronic respiratory failure in order to improve exercise tolerance, lung function and self-management. Enrolling patients in pulmonary rehabilitation programmes is a consistent help to a better control of their illness and a step forward to the international standards of treating COPD and non-COPD chronic respiratory diseases. It is evidence-based that PR is effective in reducing dyspnoea, improving health-related quality of life, reducing the number of hospital days and the utilisation of costly healthcare resources; there are also psychosocial benefits from comprehensive PR programmes in patients with COPD. PR is currently considered as effective in patients with COPD and in some patients with chronic respiratory diseases other than COPD. PMID:18822868

    Full Text Available Abstract Background Respiratory tract infections (RTIs may be more severe in those with asthma or COPD and these patients are more frequently in need of health care. The aim of the study was to describe the frequency of RTI symptoms in a general adult population and how care-seeking is associated with the presence of obstructive lung disease. Methods Cross-sectional data including spirometry and self-reported chronic diseases were collected among middle-aged and elderly subjects in the Tromsø population survey (Tromsø 6. Self- reported RTI symptoms, consultations and antibiotic use were the main outcome variables. Possible predictors of RTI symptoms were evaluated by multivariable logistic regression. Results Of the 6414 subjects included, 798 (12.4% reported RTI symptoms in the previous week. RTI symptoms were reported less frequently by subjects aged 75 years or above, than by those younger than 55 years (OR 0.5. Winter season (OR 1.28, current smoking (OR 1.60, low self-rated health (OR 1.26 and moderate to severe bronchial obstruction (OR 1.51, were also statistically significant independent predictors of RTI symptoms, but these variables did not predict RTI symptoms that had started within the previous seven days. Among subjects with RTI symptoms, 5.1% also reported a consultation with a doctor. In those with bronchial obstruction by spirometry, who did not report asthma or COPD, this frequency was 2.4%. Antibiotic treatment was reported by 7.4% of the participants, among whom one third had consulted a doctor. Antibiotics were taken more frequently when asthma or COPD was reported (13.7%, but not in subjects with bronchial obstruction who did not report these diseases (7.2%. Conclusions RTI symptoms seldom led to consultation with a doctor and not even in subjects with obstructive lung disease. This was in particular the case in subjects who did not know about their obstructive lung disease. Strategies for early diagnosis of COPD and

    Full Text Available Objective: Childhood exposure to secondhand tobacco smoke (SHS increases a child’s burden of respiratory conditions, but parental smoking bans may reduce such morbidity. This study evaluated household smoking bans and their relationship to respiratory illness in an outpatient otolaryngology clinic. Methods: The study was performed at the Heim Pal National Children’s Hospital, Ear, Nose and Throat (ENT Department (Budapest, Hungary from July to November, 2010. A consecutive series of children’s caregivers were approached to participate in a survey measuring household smoking bans, upper and lower respiratory tract symptoms and illnesses, and socioeconomic factors. Bivariate and multivariate logistic regression analyses were performed. Results: Of the 215 caregivers recruited for the study, 208 agreed to participate (response rate of 96.7%. More than half of the children were male (54%, and 39% lived in a household with at least one member who smoked. Smoking was frequently banned inside the car (91.3% and home (85.1%. Respondents felt it easiest to ask friends (97.1% and family members not living in the household (98.1% to refrain from smoking inside the home. Respondents also found it easier to ask a stranger (81.7% or a family member (61.1% not to smoke around the child. Logistic regression showed that respondents for children with a history of pneumonia found it less difficult to ask visitors in the home not to smoke compared to children without pneumonia (OR = 0.23, 95% CI = 0.06–0.98. Conversely, respondents for children who had had adenoidectomy found it over three times more difficult to ask strangers not to smoke near the child compared to those of children without adenoidectomy (OR = 3.20, 95% CI = 1.43–6.38. Conclusions: In a population of children visiting an outpatient ENT clinic in Budapest, Hungary, we found a high degree of exposure to SHS. The ease with which caregivers felt towards asking others not to smoke predicted

    Respiratory infections are well-known triggers of chronic respiratory diseases. Recently, culture-independent tools have indicated that lower airway microbiota may contribute to pathophysiologic processes associated with asthma and chronic obstructive pulmonary disease (COPD). However, the relationship between upper airway microbiota and chronic respiratory diseases remains unclear. This study was undertaken to define differences of microbiota in the oropharynx of asthma and COPD patients relative to those in healthy individuals. To account for the qualitative and quantitative diversity of the 16S rRNA gene in the oropharynx, the microbiomes of 18 asthma patients, 17 COPD patients, and 12 normal individuals were assessed using a high-throughput next-generation sequencing analysis. In the 259,572 total sequence reads, α and β diversity measurements and a generalized linear model revealed that the oropharynx microbiota are diverse, but no significant differences were observed between asthma and COPD patients. Pseudomonas spp. of Proteobacteria and Lactobacillus spp. of Firmicutes were highly abundant in asthma and COPD. By contrast, Streptococcus, Veillonella, Prevotella, and Neisseria of Bacteroidetes dominated in the healthy oropharynx. These findings are consistent with previous studies conducted in the lower airways and suggest that oropharyngeal airway microbiota are important for understanding the relationships between the various parts of the respiratory tract with regard to bacterial colonization and comprehensive assessment of asthma and COPD.

    Although a considerable number of people either witnessed directly or in the mass media the traumatic scenes of the terrorist attack that took place on March 11th, 2004 in Madrid, only a fraction of Madrid citizens developed posttraumatic symptoms. In this study, posttraumatic stress-related symptoms, degree of exposure, coping strategies related to the attack, and chronic attempts to avoid intrusive thoughts (i.e., thought suppression) were assessed in a general population Madrid sample (N=503) 2-3 weeks after the attacks. Our results showed that participants with higher scores in chronic thought suppression exhibited higher levels of PTSD symptoms. Higher scores in chronic thought suppression also correlated positively with the use of avoidant coping strategies after the attacks. We discuss the possible common roots of avoidance of intrusive thoughts and avoidant coping strategies and the implications of this relationship for the emergence of stress-related symptoms as well as for public health policies.

    Full Text Available Objectives Quantifying personal exposure to particles less than 10 micrometres in diameter (PM10 and determining the prevalence of respiratory symptoms in traffic-police officers working in Bogotá's metropolitan area. Methods This was a cross-sectional study of 574 traffic-police officers divided into two groups (477 traffic-police and 97 police working in an office. They were given a questionnaire inquiring about respiratory symptoms, toxicological medical evaluation, lung function tests and personal PM10 monitoring. The differences between groups were found using stratified analysis (i.e. comparing odds ratios. Multivariate analysis of factors related to symptoms and diagnosis of respiratory alteration was also performed. Results Respiratory symptoms concerned a higher prevalence of cough, expectoration and rhinosinusitis in the traffic-police group. Medical examination revealed that the traffic-police group had higher nasal irritation prevalence; lung function tests showed no difference. Mean PM10 levels were higher for the traffic-police group (139.4 μg/m³, compared to the office work group (86.03 μg/m³. Discussion PM10 values in both groups did not exceed allowable limits for respirable particles in the workplace according to ACGIH standards. Traffic-police exposed to air pollution had an increased risk of developing respiratory symptoms and signs, thereby agreeing with the results of this and other studies. Personal monitoring is a valuable tool when quantifying the concentration of PM10to which an individual has been exposed during a normal workday. This study contributes towards further research in to the effects of PM10 in populations at risk.

    Full Text Available There is limited information on lung function and exhaled nitric oxide fraction (FeNO in infants with recurrent lower respiratory tract symptoms. In 2000–2003, 201 recurrently symptomatic infants were referred to a tertiary center for further investigation. As part of the clinical investigation, whole-body plethysmography, tidal FeNO measurements, and skin prick tests were performed. In addition, 77 (38% of the children underwent bronchoscopy. Increased work of breathing in clinical examination (in 22%, and abnormal chest radiograph (in 30%, were associated with decreased airway conductance (sGaw z-score –1.65 (p<0.001 and p = 0.048, respectively and hyperinflation of the lungs (FRC z-score 1.65(p = 0.004 and p = 0.038, respectively. Exposure to environmental tobacco smoke (ETS was associated with FeNO 40 ppb (p = 0.009. Increased work of breathing, sGaw z-score –1.65, and FRC z-score 1.65, were associated with low FeNO (p = 0.002, p = 0.005, p = 0.026, respectively. A definitive diagnosis was made in 184 (92% children; asthma was diagnosed in 149 (74%, infection in 23 (11%, and a structural abnormality in 12 (6%. Abnormal findings in clinical examination predicted the diagnosis of asthma or a structural abnormality in 96% of cases, whereas in children with underlying respiratory infection or no definitive diagnosis, clinical examination was normal in 92% (p<0.001. In conclusion, clinical findings of bronchial obstruction predict well lung function and the diagnosis of asthma in recurrently symptomatic infants. FeNO is affected by ETS exposure, clinical state of the child, and the used methods, and the information obtained should be interpreted with care.

    Exercise training is one of the most important components in disease management for patients with chronic respiratory diseases. The clinically relevant benefits of endurance and strength training on dyspnea, exercise capacity and quality of life have been evaluated very well. However, there are some legal limitations by the German Working Group for Rehabilitation (BAR) concerning outpatient exercise training programs (beyond pulmonary rehabilitation): only group-based callisthenic training programs receive funding from health care insurances while professional equipment-based training programs are excluded despite their outstanding effectiveness.This review provides an overview on the methodology and the benefits of outpatient exercise training programs for patients with chronic respiratory diseases, and it critically discusses the organizational structures of these programs in Germany.

    Full Text Available Abstract Background Injection drug use is associated with an increased risk of human immunodeficiency virus (HIV infection and with obstructive lung diseases (OLD. Understanding how HIV and OLD may impact respiratory symptoms among injection drug users (IDUs is important to adequately care for this high-risk population. We characterized the independent and joint effects of HIV and OLD on respiratory symptoms of a cohort of inner-city IDUs. Methods Demographics, risk behavior and spirometric measurements were collected from a cross-sectional analysis of the Acquired Immunodeficiency Syndrome Link to the IntraVenous Experience study, an observational cohort of IDUs followed in Baltimore, MD since 1988. Participants completed a modified American Thoracic Society respiratory questionnaire and the Medical Research Council (MRC dyspnea score to assess respiratory symptoms of cough, phlegm, wheezing and dyspnea. Results Of 974 participants, 835 (86% were current smokers and 288 (29.6% were HIV-infected. The prevalence of OLD (FEV1/FVC ≤ 0.70 was 15.5%, and did not differ by HIV status. OLD, but not HIV, was associated with increased frequency of reported respiratory symptoms. There was a combined effect of OLD and HIV on worsening of MRC scores. OLD and HIV were independently associated with an increased odds of reporting an MRC ≥ 2 (OR 1.83 [95%CI 1.23-2.73] and 1.50 [95%CI 1.08-2.09], respectively. COPD, but not HIV, was independently associated with reporting an MRC ≥ 3 (OR 2.25 [95%CI 1.43-3.54] and 1.29 [95%CI 0.87-1.91], respectively. Conclusions While HIV does not worsen cough, phlegm or wheezing, HIV significantly increases moderate but not severe dyspnea in individuals of similar OLD status. Incorporating the MRC score into routine evaluation of IDUs at risk for OLD and HIV provides better assessment than cough, phlegm and wheezing alone.

    Full Text Available Aim: The aim of this study is to identify predictors of test anxiety in nursing students. Design: Cross sectional pilot study. Methods: A questionnaire was administered to 112 students of an Austrian nursing school (mean age = 21.42, SD = 5.21. Test anxiety (measured by the standardized PAF Test Anxiety Questionnaire, perceived chronic stress, depressive symptoms, pathological eating and further psychological and health parameters were measured. Results: We found highly significant correlations between test anxiety and working hours (0.25, depression score (0.52, emotional stability (-0.31, and perceived chronic stress (0.65 (p < 0.01, for all. Regression analysis revealed chronic stress and emotional instability as best predictors for test anxiety. Furthermore, path analysis revealed that past negative academic performance outcomes contribute to test anxiety via depressive symptoms and perceived chronic stress. Conclusion: Depressive symptoms and perceived chronic stress are strongly related to test anxiety. Therefore therapy and training methods that address depressive symptoms and perceived chronic stress, and thereby aim to modify appraisal of potential stressful situations, may be successful in addressing test anxiety.

  5. Chronic intermittent hypoxia creates the perfect storm with calamitous consequences for respiratory control.

    Science.gov (United States)

    O'Halloran, Ken D

    2016-06-01

    Obstructive sleep apnoea syndrome (OSAS) is a common respiratory disorder with devastating consequences for integrative body systems. A picture is emerging to illustrate wide-ranging deleterious consequences of disordered breathing during sleep for major homeostatic control systems, with considerable interest in cardiorespiratory and autonomic morbidity underpinning the development of hypertension. The vista is bleak when one also considers the link between OSAS and a host of other maladies. Exposure to chronic intermittent hypoxia (CIH), resulting from repeated obstructions of the pharyngeal airway, is a hallmark feature of OSAS that appears, in animal models, to drive the development and maintenance of several key morbidities. A growing body of evidence now points to aberrant respiratory plasticity at multiple levels following exposure to CIH. Herein, we review the experimental data revealing that CIH causes: respiratory muscle weakness and fatigue; impaired motor control of the upper airway; and, discordant respiratory rhythm and pattern generation. This multifaceted conspiracy creates the perfect storm with the potential to exacerbate OSAS-serving to establish an inescapable cycle of respiratory morbidity. Several pharmacological interventions in animal models appear wholly effective in preventing the calamitous consequences of CIH and may have application as adjunctive therapies in the treatment of OSAS.

    2014-02-01

    Full Text Available Objective: Exposure to Second Hand Smoke (SHS has been associated with an increased risk of respiratory symptoms, upper and lower respiratory tract diseases and an increased risk of asthma and chronic obstructive pulmonary disease. The majority of cases of mortality and morbidity is attributable to exposure of adults to SHS and is related to cardiovascular diseases and lung cancer. In Egypt, comprehensive smoke-free laws exist, however, in many workplaces they are poorly enforced consequently exposing workers to the detrimental health hazards of SHS. We aimed at determination of workplace exposure to Second Hand Smoke (SHS and its association with respiratory and sensory irritation symptoms in hospital workers in Port-said governorate in Egypt. Material and methods: A cross-sectional face to face survey was conducted by the use of a standardised questionnaire among 415 adult hospital workers; representing 50% of all employees (81% response rate; recruited from 4 randomly selected general hospitals in Port-said governorate in Egypt. Results: All hospitals employees reported exposure to SHS - on average 1.5 (SD = 2.5 hours of exposure per day. After controlling for potential confounders, exposure to SHS at work was significantly associated with an increased risk of wheezes (OR = 1.14, p < 0.01, shortness of breath (OR = 1.17, p < 0.01, phlegm (OR = 1.23, p < 0.01, running and irritated nose (OR = 1.14, p < 0.01 as well as a sore, scratchy throat (OR = 1.23. Conclusions: These findings point out that workplace exposure to SHS is evident in hospitals in Port-said governorate and that workers are adversely affected by exposure to it at work. This underlines the importance of rigorous enforcement of smoke-free policies to protect the workers' health in Egypt.

The objective of the study was evaluation of the severity of symptoms and predictive factors for depression and the existence of cognitive disorders in patients with chronic hepatitis B. Methods. A total of 150 respondents were included in this prospective study (50 patients with chronic hepatitis B, 50 patients with other chronic liver diseases and 50 healthy persons. The patients with chronic hepatitis B were homogeneous by age compared to healthy subjects (p=0.566 and patients with other chronic liver diseases (p=0.528. Assessment of intensity of depression was determined by the Hamilton Depression Rating Scale (HAMD. A Mini Mental State Examination (MMSE test was used to investigate the presence of cognitive disorders. Results. Significantly expressed depression was observed in patients with chronic hepatitis B compared with healthy persons as well as the occurrence of cognitive dysfunction (p=0.00, while in comparison with the patients with chronic nonviral liver diseases, depression was statistically significantly less markedly expressed (p=0.003. Depression and cognitive dysfunction were more noticeable in patients with chronic hepatitis B in the stage of liver cirrhosis in relation to the early stage of the disease. Multivariate analysis of variables related to the sociodemographic characteristics showed that the most significant positive predictor of depression was more expressed in older age (over 50 years (B=0.276; SE=0.092; p=0.004. Conclusion. Patients with chronic hepatitis B have a higher intensity of depression compared to healthy people, which is intensified with the progression of the disease. The highest expression of depression is expected in the elderly. Patients with chronic hepatitis B have a lower intensity of depression and fewer disorders of cognitive functions than

In Palermo, the largest metropolitan area in Sicily, urban air pollution is mainly addressed to traffic-related pollution because of lack of industrial settlements, and the presence of a temperate climate that contribute to the limited use of domestic heating plants. This study aimed to investigate the association between traffic-related air pollution and emergency room admissions for acute respiratory symptoms. Methods From January 2004 through December 2007, air pollutant concentrations and emergency room visits were collected for a case-crossover study conducted in Palermo, Sicily. Risk estimates of short-term exposures to particulate matter and gaseous ambient pollutants including carbon monoxide, nitrogen dioxide, and sulfur dioxide were calculated by using a conditional logistic regression analysis. Results Emergency departments provided data on 48,519 visits for respiratory symptoms. Adjusted case-crossover analyses revealed stronger effects in the warm season for the most part of the pollutants considered, with a positive association for PM10 (odds ratio = 1.039, 95% confidence interval: 1.020 - 1.059, SO2 (OR = 1.068, 95% CI: 1.014 - 1.126, nitrogen dioxide (NO2: OR = 1.043, 95% CI: 1.021 - 1.065, and CO (OR = 1.128, 95% CI: 1.074 - 1.184, especially among females (according to an increase of 10 μg/m3 in PM10, NO2, SO2, and 1 mg/m3 in CO exposure. A positive association was observed either in warm or in cold season only for PM10. Conclusions Our findings suggest that, in our setting, exposure to ambient levels of air pollution is an important determinant of emergency room (ER visits for acute respiratory symptoms, particularly during the warm season. ER admittance may be considered a good proxy to evaluate the adverse effects of air pollution on respiratory health.

    Full Text Available No abstract available. Article truncated after 150 words. This month's journal club reviewed the role of macrolide antibiotics in chronic respiratory disease. Macrolide usage was suggested from observational studies in Japan in diffuse panbroncholitis, a disorder associated with chronic respiratory infection, usually Pseudomonas aeruginosa (1. Clinical improvement was noted despite doses of antibiotics well below the minimal inhibitory concentration (MIC of the antibiotic. This suggested the antibiotic was likely working by an anti-inflammatory effect. These observations were extended to cystic fibrosis (CF where prophylactic macrolide therapy in CF patients infected with Pseudomonas has become standard therapy (2. More recently, low dose macrolide therapy has been applied to non-CF lung diseases such as chronic obstructive pulmonary disease (COPD, bronchiectasis and asthma. Time did not permit a review of all studies so a representative sample was discussed. In patients with COPD, the four randomized, placebo-controlled trials reviewed all suggested that chronic therapy with macrolide antibiotics reduced COPD exacerbations (3-5. This ...

    Full Text Available Background and Objectives: Attention is a central mechanism controlling information processing, activating and inhibiting processes, and forming a complex system including diferent networks in specific areas of the brain¹. To correctly assess the role of attention in schizophrenia it is necessary to discriminate its different attentional components, which may by selectively altered. Attention span, focused attention, selective attention, sustained attention and inhibitory response, were assessed in patients with chronic schizophrenia and healthy matched controls. Methods: The study included 32 patients diagnosed with chronic schizophrenia and 32 healthy subjects. The groups were matched in age, sex, and level of education. Symptom severity (positive symptoms, negative symptoms, and general psychopathology was assessed with the Scale for the Assessment of Positive and Negative Symptoms (SAPS and SANS. Attentional components were measured by Forward Digit Span, Symbol Search, Digit Symbol Coding, Stroop Test and Picture Completion. Results: Schizophrenic patients exhibited lower attentional scores in all tests compared to the control group. Inhibitory control and sustained attention were the most affected traits in schizophrenic patients. An inverse correlation was observed between inhibitory control and delusions and disorganized thinking. No significant correlations were observed between negative symptoms and attentional performance. Conclusions: The pattern of results obtained in this paper evidences the role of an inhibitory control deficit in patients with chronic schizophrenia that could also be involved in other attentional and cognitive failures, and also be connected to positive symptoms.

These variables include peak oxygen uptake (VO2 <85% predicted, anaerobic threshold <40%  VO2max predicted, VO2-work rate slope <8.6 mL/watt, oxygen pulse <80% predicted, and ventilatory equivalents for O2 and CO2 at nadir of >31 and >34, respectively. Some of these six variables may be normal while the others are abnormal in patients with chronic obstructive pulmonary disease (COPD. This may result in confusion when using the interpretation algorithm for diagnostic purposes. We therefore hypothesized that patients found to have abnormal values for all six variables would have worse cardiovascular function than patients with abnormal values for none or some of these variables.Methods: In this cross-sectional comparative study, 58 COPD patients attending a university teaching hospital underwent symptom-limited CPET with multiple lactate measurements. Patients with abnormal values in all six IPO-related variables were assigned to an IPO group while those who did not meet the requirements for the IPO group were assigned to a non-IPO group. Cardiovascular function was measured by two-dimensional echocardiography and Δlactate/ΔVO2, and respiratory dynamics were compared between the two groups.Results: Fourteen IPO and 43 non-IPO patients were entered into the study. Both groups were similar with regard to left ventricular ejection fraction and right ventricular morphology (P>0.05 for both. At peak exercise, both groups reached a similar heart rate level and Δlactate/ΔVO2. The IPO patients had an

    Vestibular signals are of significant importance for variable functions including gaze stabilization, spatial perception, navigation, cognition, and bodily self-consciousness. The vestibular network governs functions that might be impaired in patients affected with vestibular dysfunction. It is currently unclear how different brain regions/networks process vestibular information and integrate the information into a unified spatial percept related to somatosensory awareness and whether people with recurrent balance complaints have a neural signature as a trait affecting their development of chronic symptoms of vertigo. Pivotal evidence points to a vestibular-related brain network in humans that is widely distributed in nature. By using resting state source localized electroencephalography in non-vertiginous state, electrophysiological changes in activity and functional connectivity of 23 patients with balance complaints where chronic symptoms of vertigo and dizziness are among the most common reported complaints are analyzed and compared to healthy subjects. The analyses showed increased alpha2 activity within the posterior cingulate cortex and the precuneues/cuneus and reduced beta3 and gamma activity within the pregenual and subgenual anterior cingulate cortex for the subjects with balance complaints. These electrophysiological variations were correlated with reported chronic symptoms of vertigo intensity. A region of interest analysis found reduced functional connectivity for gamma activity within the vestibular cortex, precuneus, frontal eye field, intra-parietal sulcus, orbitofrontal cortex, and the dorsal anterior cingulate cortex. In addition, there was a positive correlation between chronic symptoms of vertigo intensity and increased alpha-gamma nesting in the left frontal eye field. When compared to healthy subjects, there is evidence of electrophysiological changes in the brain of patients with balance complaints even outside chronic symptoms of vertigo

    Full Text Available Abstract Background Smokers attribute respiratory symptoms, even when severe, to everyday causes and not as indicative of ill-health warranting medical attention. The aim of this pilot study was to conduct a structured vignette survey of people attending general practice to determine when they would advise a person with respiratory symptoms to consult a medical practitioner. Particular reference was made to smoking status and lung cancer. Methods Participants were recruited from two general practices in Western Australia. Respondents were invited to complete self-administered questionnaires containing nine vignettes chosen at random from a pool of sixty four vignettes, based on six clinical variables. Twenty eight vignettes described cases with at least 5% risk of cancer. For analysis these were dubbed 'cancer vignettes'. Respondents were asked if they would advise a significant other to consult a doctor with their respiratory symptoms. Logistic regression and non-parametric tests were used to analyse the data. Results Three hundred questionnaires were distributed and one hundred and forty completed responses were collected over six weeks. The majority (70.3% of respondents were female aged forty and older. A history of six weeks' of symptoms, weight loss, cough and breathlessness independently increased the odds of recommending a consultation with a medical practitioner by a factor of 11.8, 2.11, 1.40 and 4.77 respectively. A history of smoking independently increased the odds of the person being thought 'likely' or 'very likely' to have cancer by a factor of 2.46. However only 32% of cancer vignettes with a history of cigarette smoking were recognised as presentations of possible cancer. Conclusion Even though a history of cigarette smoking was more likely to lead to the suggestion that a symptomatic person may have cancer we did not confirm that smokers would be more likely to be advised to consult a doctor, even when presenting with common

    Few studies have assessed the quality of life (QOL) related to chronic respiratory diseases in the elderly. In the framework of the geriatric study on the health effects of air quality in elderly care centers (GERIA) study, a questionnaire was completed by elderly subjects from 53 selected nursing homes. It included various sections in order to assess respiratory complaints, QOL (World Health Organization QOL (WHOQOL)-BREF), and the cognitive and depression status. The outcome variables were the presence of a score lower than 50 (current wheezing, asthma, and allergic rhinitis were considered as potential risk factors. The surveyed sample was (n = 887) 79% female, with a mean age of 84 years (SD: 7 years). In the multivariable analysis, a score of <50 in the physical domain was associated with wheezing in the previous 12 months (odds ratio (OR): 2.03, confidence interval (CI): 1.25-3.31) and asthma (OR: 1.95, CI: 1.12-3.38). The psychological domain was related with a frequent cough (OR: 1.43, CI: 0.95-2.91). A score of <50 in the environmental domain was associated with chronic bronchitis (OR: 2.89, CI: 1.34-6.23) and emphysema (OR: 3.89, CI: 1.27-11.88). In view of these findings, the presence of respiratory diseases seems to be an important risk factor for a low QOL among elderly nursing home residents. PMID:26965222

    To assess the ability of magnetic resonance (MR) imaging to determine the prognosis of spinal cord injury in the chronic stage and to detect the injured myelomere, 39 patients were examined with MR images obtained by T1-weighted spin echo method 5 months to 4 years and 8 months (mean, one year and 5 months) after they had sustained spinal cord injury. According to hypointensity area of the ventrodorsad diameter of the spinal cord, MR images were classified as non-hypointensity (I), discrete (II), central (III), large cavity (IV), and transverse (V). The most common type was III (25%), followed by IV (26%), II (18%), V (15%), and I (13%). In 21 patients with bone injury, 14 (67%) had type IV or V, in contrast to 2 (11%) of 18 patients without bone injury. Increased hypointensity on MR images was associated with severer injury of the spinal cord. When hypointensity accounted for less than 1/2 of the ventrodorsad diameter of the spinal cord, walking ability was recovered in more than 80% of the patients. When less than 1/3 of the ventrodorsad diameter of the spinal cord was seen as hypointensity, arm function was well preserved, and the anterior horn of gray matter was found less injured. In 60% of the patients, there was difference in the injured level of myelomere between MR images and the neurological examination; the injured level of myelomere tended to be more cephalad level in the neurological examination than MR appearance.(N.K.).

    Chronic bladder ischemia is potentially a common cause of lower urinary tract symptoms in the elderly. Epidemiological studies have shown a close association between lower urinary tract symptoms and vascular risk factors for atherosclerosis, and investigations using transrectal color Doppler ultrasonography have shown a negative correlation between decreased lower urinary tract perfusion and International Prostate Symptom Score in elderly patients with lower urinary tract symptoms. Bladder blood flow is also known to decrease in men with bladder outlet obstruction as a result of benign prostatic hyperplasia. Studies in animal models suggest that chronic bladder ischemia and repeated ischemia/reperfusion during a micturition cycle might produce oxidative stress, leading to denervation of the bladder and the expression of tissue-damaging molecules in the bladder wall, which could be responsible for the development of bladder hyperactivity progressing to bladder underactivity. The effects of drugs with different mechanisms of action; for example, α1-adrenoceptor antagonists, phosphodiesterase type 5 inhibitors, free radical scavengers and β3-adrenoceptor agonist, have been studied in animal models of chronic bladder ischemia. The drugs, representing different treatment principles for increasing blood flow and decreasing oxidative stress, showed protective effects not only on urodynamic parameters, but also on negative effects on muscle contractility and on detrimental structural bladder wall changes. Improvement of lower urinary tract perfusion and control of oxidative stress can be considered new therapeutic strategies for treatment of bladder dysfunction induced by chronic ischemia.

    Mucus hypersecretion is a cardinal sign of both acute and chronic pulmonary diseases. Normally, mucus protects respiratory tract, but its overproduction leads to airway obstruction and promotes bacterial colonization. In the first part of our review we outlined the possible factors responsible for mucus hypersecretion and clinical consequences of this process. Mucolytic agents such as Ambroxol and N-acetylcysteine are able to alter the secretion of mucus and its physical properties which results in improvement of mucociliary clearance. Mechanisms of action and indications for use of mucolytics are presented. Mucolytics have been shown to have a role in improving lung functions and patients' quality of life. Undoubtedly they are useful as an adjunctive therapy of respiratory tract disorders. PMID:12053600

    Full Text Available Abstract Background Probiotics purportedly reduce symptoms of gastrointestinal and upper respiratory-tract illness by modulating commensal microflora. Preventing and reducing symptoms of respiratory and gastrointestinal illness are the primary reason that dietary supplementation with probiotics are becoming increasingly popular with healthy active individuals. There is a paucity of data regarding the effectiveness of probiotics in this cohort. The aim of this study was to evaluate the effectiveness of a probiotic on faecal microbiology, self-reported illness symptoms and immunity in healthy well trained individuals. Methods Competitive cyclists (64 males and 35 females; age 35 ± 9 and 36 ± 9 y, VO2max 56 ± 6 and 52 ± 6 ml.kg-1.min-1, mean ± SD were randomised to either probiotic (minimum 1 × 109 Lactobacillus fermentum (PCC® per day or placebo treatment for 11 weeks in a double-blind, randomised, controlled trial. The outcome measures were faecal L. fermentum counts, self-reported symptoms of illness and serum cytokines. Results Lactobacillus numbers increased 7.7-fold (90% confidence limits 2.1- to 28-fold more in males on the probiotic, while there was an unclear 2.2-fold (0.2- to 18-fold increase in females taking the probiotic. The number and duration of mild gastrointestinal symptoms were ~2-fold greater in the probiotic group. However, there was a substantial 0.7 (0.2 to 1.2 of a scale step reduction in the severity of gastrointestinal illness at the mean training load in males, which became more pronounced as training load increased.

    associated with increases in respiratory diseases. The objective of this study was to evaluate the prevalence of respiratory symptoms among farmers and the associations of these with occupational risk factors. METHODS: This cross-sectional study was undertaken in 1996 with 1,379 farmers from Southern Brazil. Sociodemographic and farming-production parameters were collected, as were levels of exposure to organic and mineral dusts. Respiratory symptoms were assessed by a modified version of American Thoracic Society-Division of Lung Disease questionnaire. Multiple logistic regression analysis was used in analyses, controlling for confounding factors. RESULTS: The majority (52% of interviewees worked in activities with intense exposure to dust. Workers on farms with better economic indicators had a lower prevalence of respiratory symptoms. Poultry workers showed more symptoms of chronic respiratory disease (OR=1.60; 95% CI: 1.05-2.42. Farmers exposed to high concentrations of dust had more than 70% higher risk of asthma symptoms (OR=1.71; 95% CI: 1.10-2.67 and chronic respiratory disease symptoms (OR=1.77; 95% CI: 1.25-2.50. CONCLUSIONS: The rural workers studied herein were exposed to high levels of organic and mineral dusts. Those exposed to higher dust concentrations, such as poultry workers, showed an increased risk of work-related respiratory symptoms. The implementation of respiratory protection programs is recommended, emphasizing workers involved with poultry production.

    2012-06-01

    Full Text Available Abstract Background Frequent exacerbations induce a high burden to Chronic Obstructive Pulmonary Disease (COPD. We investigated the course of exacerbations in the published COSMIC study that investigated the effects of 1-year withdrawal of fluticasone after a 3-month run-in treatment period with salmeterol/fluticasone in patients with COPD. Methods In 373 patients, we evaluated diary cards for symptoms, Peak Expiratory Flow (PEF, and salbutamol use and assessed their course during exacerbations. Results There were 492 exacerbations in 224 patients. The level of symptoms of cough, sputum, dyspnea and nocturnal awakening steadily increased from 2 weeks prior to exacerbation, with a sharp rise during the last week. Symptoms of cough, sputum, and dyspnea reverted to baseline values at different rates (after 4, 4, and 7 weeks respectively, whereas symptoms of nocturnal awakening were still increased after eight weeks. The course of symptoms was similar around a first and second exacerbation. Increases in symptoms and salbutamol use and decreases in PEF were associated with a higher risk to develop an exacerbation, but with moderate predictive values, the areas under the receiver operating curves ranging from 0.63 to 0.70. Conclusions Exacerbations of COPD are associated with increased symptoms that persist for weeks and the course is very similar between a first and second exacerbation. COPD exacerbations are preceded by increased symptoms and salbutamol use and lower PEF, yet predictive values are too low to warrant daily use in clinical practice.

    Full Text Available Little is known about the serologic responses to Pneumocystis jirovecii major surface glycoprotein (Msg antigen in African cohorts, or the IgM responses to Msg in HIV-positive and HIV-negative persons with respiratory symptoms.We conducted a prospective study of 550 patients, both HIV-positive (n = 467 and HIV-negative (n = 83, hospitalized with cough ≥2 weeks in Kampala, Uganda, to evaluate the association between HIV status, CD4 cell count, and other clinical predictors and antibody responses to P. jirovecii. We utilized ELISA to measure the IgM and IgG serologic responses to three overlapping recombinant fragments that span the P. jirovecii major surface glycoprotein: MsgA (amino terminus, MsgB (middle portion and MsgC1 (carboxyl terminus, and to three variations of MsgC1 (MsgC3, MsgC8 and MsgC9.HIV-positive patients demonstrated significantly lower IgM antibody responses to MsgC1, MsgC3, MsgC8 and MsgC9 compared to HIV-negative patients. We found the same pattern of low IgM antibody responses to MsgC1, MsgC3, MsgC8 and MsgC9 among HIV-positive patients with a CD4 cell count <200 cells/µl compared to those with a CD4 cell count ≥200 cells/µl. HIV-positive patients on PCP prophylaxis had significantly lower IgM responses to MsgC3 and MsgC9, and lower IgG responses to MsgA, MsgC1, MsgC3, and MsgC8. In contrast, cigarette smoking was associated with increased IgM antibody responses to MsgC1 and MsgC3 but was not associated with IgG responses. We evaluated IgM and IgG as predictors of mortality. Lower IgM responses to MsgC3 and MsgC8 were both associated with increased in-hospital mortality.HIV infection and degree of immunosuppression are associated with reduced IgM responses to Msg. In addition, low IgM responses to MsgC3 and MsgC8 are associated with increased mortality.

    Full Text Available Many Veterans returning from service in Operation Iraqi Freedom/Operation Enduring Freedom (OIF/OEF experience chronic pain. What is not known is whether for some OIF/OEF Veterans this pain is part of a larger condition of diffuse multisystem symptoms consistent with chronic multisymptom illness (CMI. We use data from a prospective longitudinal study of OIF/OEF Veterans to determine the frequency of CMI. We found that 1 yr after deployment, 49.5% of OIF/OEF Veterans met criteria for mild to moderate CMI and 10.8% met criteria for severe CMI. Over 90% of Veterans with chronic pain met criteria for CMI. CMI was not completely accounted for either by posttraumatic stress disorder or by predeployment levels of physical symptoms. Veterans with symptoms consistent with CMI reported significantly worse physical health function than Veterans who did not report symptoms consistent with CMI. This study suggests that the presence of CMI should be considered in the evaluation of OIF/OEF Veterans. Further, it suggests that the pain management for these Veterans may need to be tailored to take CMI into consideration.

    AIM: To evaluate the prevalence of chronic gastroin-testinal symptoms and their impact on health-related quality of life (HRQOL) in the Korean population. METHODS: A cross-sectional survey, using a reliable and valid Rome 1I based questionnaire, was per-formed on randomly selected residents, between 18 and 69 years in age. All respondents were interviewed at their homes or offices by a team of interviewers. The impact of chronic gastrointestinal symptoms on HRQOL was assessed using the Korean version of the 36-item Short-Form general health survey (SF-36). RESULTS: Of the 1807 eligible subjects, 1417 (78.4%: male 762; female 655) were surveyed. Out of the respondents, 18.6% exhibited at least one chronic gastrointestinal symptom. The prevalence of gastro-esophageal reflux disease (GERD), defined as heart-burn and/or acid regurgitation experienced at least weekly, was 3.5% (95% CI, 2.6-4.5). The prevalence of uninvestigated dyspepsia, irritable bowel syndrome (IBS) and chronic constipation based on Rome Ⅱ cri-teria were 11.7% (95% CI, 10.1-13.5), 2.2% (95% CI, 1.5-3.1), and 2.6% (95% CI, 1.8-3.5) respectively. Compared with subjects without chronic gastrointesti-nal symptoms (n = 1153), those with GERD (n = 50), uninvestigated dyspepsia (n = 166) and IBS (n=31) had significantly worse scores on most domains of the SF-36 scales. CONCLUSION: The prevalence of GERD, uninvesti-gated dyspepsia and IBS were 3.5%, 11.7% and 2.2% respectively, in the Korean population. The health-related quality of life was significantly impaired in sub-jects with GFRD, uninvestigated dyspepsia and IBS in this community.

    2005-07-01

    Full Text Available Abstract Objectives Validated or standardized self-report questionnaires used in research studies and clinical evaluation of chronic fatigue syndrome (CFS generally focus on the assessment of fatigue. There are relatively few published questionnaires that evaluate case defining and other accompanying symptoms in CFS. This paper introduces the self-report CDC CFS Symptom Inventory and analyzes its psychometric properties. Methods One hundred sixty-four subjects (with CFS, other fatiguing illnesses and non fatigued controls identified from the general population of Wichita, Kansas were enrolled. Evaluation included a physical examination, a standardized psychiatric interview, three previously validated self-report questionnaires measuring fatigue and illness impact (Medical Outcomes Survey Short-Form-36 [MOS SF-36], Multidimensional Fatigue Inventory [MFI], Chalder Fatigue Scale, and the CDC CFS Symptom Inventory. Based on theoretical assumptions and statistical analyses, we developed several different Symptom Inventory scores and evaluated them on their ability to differentiate between participants with CFS and non-fatigued controls. Results The Symptom Inventory had good internal consistency and excellent convergent validity. A Total score (all symptoms, Case Definition score (CFS case defining symptoms and Short Form score (6 symptoms with minimal correlation differentiated CFS cases from controls. Furthermore, both the Case Definition and Short Form scores distinguished people with CFS from fatigued subjects who did not meet criteria for CFS. Conclusion The Symptom Inventory appears to be a reliable and valid instrument to assess symptoms that accompany CFS. It is a positive addition to existing instruments measuring fatigue because it allows other dimensions of the illness to be assessed. Further research is needed to confirm and replicate the current findings in a normative population.

    Abstract Treatment of periodontal diseases has been associated with benefit outcomes for patients with chronic obstructive pulmonary disease (COPD). However, no population-based cohort study has been conducted. We evaluated this relationship by retrospective cohort study using a large population data. Using the National Health Insurance claims data of Taiwan, we identified 5562 COPD patients with periodontal diseases who had received periodontal treatment as the treatment group. The comparison group was selected at a 1:1 ratio matched by the propensity score estimated with age, sex, date of COPD diagnosis and periodontal treatment, and comorbidities. Both groups were followed up for 5 years to compare risks of acute exacerbation, pneumonia, and acute respiratory failure. The incidence rates of adverse respiratory events were significantly lower in the treatment group than in the comparison group: 3.79 versus 4.21 per 100 person-years for emergency room visits, 2.75 versus 3.65 per 100 person-years for hospitalizations, and 0.66 versus 0.75 per 100 person-years for intensive care unit admissions. The treatment group also had a 37% reduced risk of deaths (1.81 vs 2.87 per 100 person-years), with an adjusted hazard ratio of 0.57 (95% confidence interval 0.52–0.62). Periodontal treatment for COPD patients could reduce the risk of adverse respiratory events and mortality. The adequate periodontal health care is important for COPD patients with periodontal diseases. PMID:27196497

  11. The impact of symptom burden on patient quality of life in chronic myeloid leukemia.

    2014-01-01

    Patients with chronic myeloid leukemia (CML) in chronic phase are living longer on BCR-ABL1 tyrosine kinase inhibitor (TKI) therapy, placing emphasis on issues related to symptom burden and quality of life (QoL). Furthermore, the potential for adverse events with longer-term therapy may result in dose adjustments, treatment discontinuation, or nonadherence, all of which may negatively affect treatment efficacy and QoL. However, instruments to specifically measure the impact of symptom burden and treatment on health-related QoL in patients with CML have not been widely available until recently. The FACT-Leu is a validated tool that measures leukemia-specific and more general QoL concerns. Other tools specific to CML, including the MDASI-CML and the EORTC QLQ-CML24, are undergoing validation. Here, we describe TKI therapy-related symptom burden and its effect on adherence and treatment response, outline instruments to measure symptom burden and QoL in CML, and summarize the available clinical data on QoL of patients on TKI therapy. QoL is an aspect of CML disease management that will continue to gain prominence in the coming years. We believe that the instruments developed now will have a role in informing treatment decisions in routine practice and allowing clinicians to proactively address issues related to symptom burden and QoL.

  12. Radiotherapy for breast carcinoma: an evaluation of the relationship between the central lung depth and respiratory symptoms

    International Nuclear Information System (INIS)

    Purpose: Treatment for early breast cancer is multimodal with radiotherapy playing a fundamental role. This study investigated the relationship between the depth of lung incorporated in the tangential chest wall fields and self-reported respiratory symptoms. Method: A randomised trial was conducted with 350 patients from one radiotherapy centre, randomised to one of two lung depth categories (0-2 cm or 0-2.5 cm). The primary outcome measure was the self-reported incidence of dry unproductive cough (DUC) post-treatment. Results: On an intention to treat basis no difference in post-treatment symptoms for DUC could be identified between the two lung depth categories. A logistic regression analysis identified patient age, the use of nodal irradiation, and symptoms of DUC pre-treatment as significant in determining the risk of patients developing symptoms post-treatment. Conclusion: These results confirm the importance of considering total volume of lung incorporated in the radiotherapy portals (identified by the relationship between reported symptoms and the use of nodal irradiation). The results of this study serve to further emphasise the need for evidence-based study into the radiotherapy policies employed in the UK

    Full Text Available We studied the role of base excess (BE as marker of chronic hypercapnia and survival in patients with chronic obstructive pulmonary disease (COPD and chronic hypercapnic respiratory failure (CHRF. Moreover, it was investigated whether the effects of non-invasive positive pressure ventilation (NPPV on CHRF were reflected in BE and survival. In 240 (160 without exacerbation patients with COPD (mean±SD FEV1 30.7±9.7 %pred; PaCO2 56.9±9.9 mmHg body-mass index (BMI, lung function, respiratory muscle function, blood gases and 6-minute walking distance (6-MWD were assessed prior to initiation of NPPV. In addition, the changes of risk factors 6.3±2.9 months after initiation of NPPV were evaluated. Overall mortality during the follow-up time (26.0±24.5 months was 34.6%. Deaths resulted predominantly from respiratory causes (65.1%; among those, respiratory failure was most frequent (85.2%. Univariate analysis revealed BMI, FEV1, maximal inspiratory pressure (PImax, inspiratory load (P0.1, haemoglobin, 6-MWD, hyperinflation (IC/TLC, RV/TLC, blood gases and BE to be associated (p<0.05 each with prognosis. In multivariate analyses, however, only BMI, RV/TLC and BE turned out to be independent cross-sectional predictors (p<0.05. Kaplan-Meier analyses showed that BE had predictive value particularly in patients with BMI25 kg·m–2, RV/TLC70 % and PaCO257 mmHg. Furthermore, changes of BMI, RV/TLC and BE (p<0.01 were associated with improved prognosis in severe hypercapnic COPD. In patients with COPD and CHRF, BE was a prognostic marker for mortality, that was independent from other factors, particularly PaCO2. In addition, reversal of CHRF was reflected in BE and appeared to have an impact on prognosis.

  14. Respiratory muscle pacing with chronically implanted intramuscular Permaloc electrodes: A feasibility study

    James S. Walter, PhD

    2011-02-01

    Full Text Available We tested the feasibility of stimulating upper-intercostal and abdominal muscles plus the diaphragm by using chronically implanted intramuscular electrodes. During two survival surgeries with six dogs, intramuscular electrodes were implanted bilaterally in the three respiratory muscles. Standard stimulation of the diaphragm was conducted. The dorsolateral and ventrolateral abdominal wall areas were stimulated with a 25 mA current. The second to fourth intercostal spaces were stimulated to elicit the largest tidal volume associated with the least coactivation of the serratus and latissimus muscles. Lone diaphragm and upper-intercostal muscle pacing produced inhaled tidal volumes (mean +/- standard error of the mean of 293 +/- 36 mL and 59 +/- 17 mL, respectively. Lone abdominal muscle pacing produced an exhaled volume of 55 +/- 17 mL. Combined pacing of diaphragm and intercostal muscles increased the inhaled volume to 389 +/- 39 mL. The addition of abdominal pacing following the combined stimulation of diaphragm and intercostals increased the exhaled volume to 472 +/- 54 mL. During autopsy, dislodgement of the electrodes overlying the ribs was a concern and probably resulted from loose animal jackets. Chronic intramuscular Permaloc electrodes can be implanted in several respiratory muscles and increase tidal volumes more than diaphragm stimulation alone.

    Full Text Available Abstract Background The etiology and treatment of chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS remain poorly understood. Pain, lower urinary tract voiding symptoms and negative impact on quality of life (QOL are the most common complaints. Acupuncture, which has been widely used to treat painful and chronic conditions, may be a potential treatment to alleviate the constellation of symptoms experienced by men with CP/CPPS. The purpose of our study was to assess the impact of standardized full body and auricular acupuncture in men refractory to conventional therapies and collect pilot data to warrant further randomized trials. Methods Ten men diagnosed with category IIIA or IIIB CP/CPPS >6 months, refractory to at least 1 conventional therapy (antibiotics, anti-inflammatory agents, 5-α reductase inhibitors, α-1 blockers and scoring >4 on the pain subset of the NIH-CPSI were prospectively analyzed in an Institutional Review Board (IRB approved, single-center clinical trial (Columbia University Medical Center IRB#AAAA-7460. Standardized full body and auricular acupuncture treatment was given twice weekly for 6 weeks. The primary endpoints were total score of the NIH-CPSI and assessment of serious adverse events. The secondary endpoints were individual scores of the NIH-CPSI and QOL questionnaire scores of the short-form 36 (SF-36. Results The median age of the subjects was 36 years (range 29–63. Decreases in total NIH-CPSI scores (mean ± SD after 3 and 6 weeks from baseline (25.1 ± 6.6 were 17.6 ± 5.7 (P Conclusion The preliminary findings, although limited, suggest the potential therapeutic role of acupuncture in the treatment of CP/CPPS. Data from this and previous studies warrant randomized trials of acupuncture for CP/CPPS and particular attention towards acupuncture point selection, treatment intervention, and durability of acupuncture.

    Full Text Available Background and objective: increase in renal blood flow in response to certain stimuli such as dopamine infusion, oral protein load, and amino acid infusion. Reduced or absent renal functional reserve (RFR is an early index of renal impairment. Our work studies the (RFR in Chronic Obstructive Pulmonary Disease (COPD patients with chronic compensated type II respiratory failure. Methods: Our study included 15 COPD patients with compensated type II respiratory failure and 5 normal controls. The patient group had mean Pa O2 56.5±6.4 and Pa CO2 56.5±3.2, while in normal controls the mean Pa O2 was 97.4 ± o.3 and Pa CO2 was 42.3 ± 1.2. Hypoxic patients (Pa O2or = 60 mm Hg and Sa O2 > or = 90 % without rise of PaCO2 within 2 hours before and during the study. The pulsatility index (PI, an index of reno-vascular resistance (RVR, was measured non invasively by Doppler Ultrasonograghy at baseline and 20 minutes after infusion of dopamine in diuretic dose. Results: The baseline PI was nearly similar in the control group and in COPD patients (no significant difference, the PI fell significantly in the control group after dopamine infusion from 1.03 ± 0.14 to 0.83 ± 0.1(P< 0.05, but increased significantly in COPD patients from 1.02 ± 0.12 to1.18 ± 0.13 (P<0.05 after dopamine infusion. Conclusion: Renal functional reserve is impaired in hypercapnic COPD patients and this may be a factor in the development of edema frequently seen in these patients

    The role of eosinophil cationic protein (ECP) in allergic inflammatory reaction has been documented in experimental and clinical studies, but a clinical usefulness is still discussed. In the study serum level of ECP has been evaluated in children with allergic diseases of the respiratory system in exacerbation and remission of symptoms for purpose of monitoring of disease course. In 111 children aged 12.0 +/- 3.3 yrs with atopic bronchial asthma and/ or allergic rhinits ECP serum concentrations have been determined in following groups: children with grass pollen hypersensitivity (group P, 17 female and 41 male), children with hypersensitivity to D. pteronyssinus and D. farinae (group D, 16 female and 37 male) and controls without allergic hypersensitivity with negative prick skin tests (19 children, 11 female and 5 male). All children have been qualified to immunotherapy with pollen or mite allergens (Allergovit or Novo-Helisen, Nexter, Allergopharma) and ECP evaluation was performed before, during and after therapy. Serum ECP and IgE levels have been determined with CAP-system (Pharmacia) and obtained results related to clinical symptoms. In all analyzed children serum total IgE has been significantly increased in relation to controls. Serum ECP levels have been increased during clinical exacerbation of symptoms in observed children and parallel with clinical score of symptoms, especially during pollen season. Authors conclude that a degree of increase of serum ECP level is parallel with clinical score of symptoms, especially during highest exposition to pollen allergens. Observed changes of serum ECP levels during immunotherapy suggest the close relationship with allergic inflammatory reaction and indicate clinical usefulness for monitoring of this process.

    The objective of this cross-sectional study was to investigate the prevalence of self-reported respiratory, ocular and cutaneous symptoms in subjects working at indoor swimming pools and to assess the relationship between frequency of declared symptoms and occupational exposure to disinfection by-products (DBPs). Twenty indoor swimming pools in the Emilia Romagna region of Italy were included in the study. Information about the health status of 133 employees was collected using a self-administered questionnaire. Subjects working at swimming pools claimed to frequently experience the following symptoms: cold (65.4%), sneezing (52.6%), red eyes (48.9%) and itchy eyes (44.4%). Only 7.5% claimed to suffer from asthma. Red eyes, runny nose, voice loss and cold symptoms were declared more frequently by pool attendants (lifeguards and trainers) when compared with employees working in other areas of the facility (office, cafe, etc.). Pool attendants experienced generally more verrucas, mycosis, eczema and rash than others workers; however, only the difference in the frequency of self-declared mycosis was statistically significant (p = 0.010). Exposure to DBPs was evaluated using both environmental and biological monitoring. Trihalomethanes (THMs), the main DBPs, were evaluated in alveolar air samples collected from subjects. Swimming pool workers experienced different THM exposure levels: lifeguards and trainers showed the highest mean values of THMs in alveolar air samples (28.5 +/- 20.2 microg/m(3)), while subjects working in cafe areas (17.6 +/- 12.1 microg/m(3)), offices (14.4 +/- 12.0 microg/m(3)) and engine rooms (13.6 +/- 4.4 microg/m(3)) showed lower exposure levels. Employees with THM alveolar air values higher than 21 microg/m(3) (median value) experienced higher risks for red eyes (OR 6.2; 95% CI 2.6-14.9), itchy eyes (OR 3.5; 95% CI 1.5-8.0), dyspnea/asthma (OR 5.1; 95% CI 1.0-27.2) and blocked nose (OR 2.2; 95% CI 1.0-4.7) than subjects with less exposure

    Previous studies have examined sex differences in physiological responding, including respiratory sinus arrhythmia (RSA) reactivity in response to changing stimulus conditions involving situation specific or gender related cues, in children and adolescents. The present study examined whether RSA reactivity moderates the relation between aggression and internalizing symptoms and whether there are sex differences in this effect. Participants were 82 adolescents (M age = 12.1 years; 44 girls) from the general middle-school population. Peer nominations assessed aggression and internalizing symptoms, and RSA reactivity (defined as change in RSA from baseline to task) was recorded while participants anticipated and responded to an 85 dB signaled white-noise burst. For girls, internalizing symptoms were associated with aggression only if girls showed low RSA reactivity from baseline to task; there was no effect for boys. This association was absent when girls showed high RSA reactivity. Thus, child sex appears to influence not only levels of physiological responding but also relations of physiological responding to comorbidity of adjustment problems. PMID:26159768

  14. Lipid-Laden Alveolar Macrophages and pH Monitoring in Gastroesophageal Reflux-Related Respiratory Symptoms

    Directory of Open Access Journals (Sweden)

    2012-01-01

    Full Text Available Lipid-laden alveolar macrophages and pH monitoring have been used in the diagnosis of chronic aspiration in children with gastroesophageal reflux (GER. This study was conducted to prove a correlation between the detection of alimentary pulmonary fat phagocytosis and an increasing amount of proximal gastroesophageal reflux. It was assumed that proximal gastroesophageal reflux better correlates with aspiration than distal GER. Patients from 6 months to 16 years with unexplained recurrent wheezy bronchitis and bronchial hyperreactivity, or recurrent pneumonia with chronic cough underwent 24-hour double-channel pH monitoring and bronchoscopy with bronchoalveolar lavage (BAL. Aspiration of gastric content was determined by counting lipid laden alveolar macrophages from BAL specimens. There were no correlations between any pH-monitoring parameters and counts of lipid-laden macrophages in the whole study population, even when restricting analysis to those with abnormal reflux index expressing clinically significant GER. Quantifying lipid-laden alveolar macrophages from BAL in children with gastroesophageal-related respiratory disorders does not have an acceptable specificity to prove chronic aspiration as an underlying etiology. Therefore, research for other markers of pulmonary aspiration is needed.

    2013-01-01

    Full Text Available Chronic stable angina (CSA is a significant problem in the United States that can negatively impact patient quality of life (QoL. An accurate assessment of the severity of a patient’s angina, the impact on their functional status, and their risk of cardiovascular complications is key to successful treatment of CSA. Active communication between the patient and their healthcare provider is necessary to ensure that patients receive optimal therapy. Healthcare providers should be aware of atypical symptoms of CSA in their patients, as patients may continue to suffer from angina despite the availability of multiple therapies. Patient questionnaires and symptom checklists can help patients communicate proactively with their healthcare providers. This paper discusses the prevalence of CSA, its impact on QoL, and the tools that healthcare providers can use to assess the severity of their patients’ angina and the impact on QoL.

    Vitamin B12 deficiency is common in developing countries and should be suspected in patients with unexplained anaemia or neurological symptoms. Dermatological manifestations associated with this deficiency include skin hyper- or hypopigmentation, angular stomatitis and hair changes. We report a case of a 28-year-old man who presented to the Sultan Qaboos University Hospital in Muscat, Oman, in November 2013 with localised hyperpigmentation of the palmar and dorsal aspects of both hands of two months' duration. Other symptoms included numbness of the hands, anorexia, weight loss, dizziness, fatigability and a sore mouth and tongue. There was no evidence of hypocortisolaemia and a literature search revealed a possible B12 deficiency. The patient had low serum B12 levels and megaloblastic anaemia. An intrinsic factor antibody test was negative. A gastric biopsy revealed chronic gastritis. After B12 supplementation, the patient's symptoms resolved. Family physicians should familiarise themselves with atypical presentations of B12 deficiency. Many symptoms of this deficiency are reversible if detected and treated early. PMID:26357561

    Emerging evidence suggests schizophrenia to involve widespread alterations in the macroscale wiring architecture of the human connectome. Recent findings of attenuated connectome alterations in unaffected siblings of schizophrenia patients suggest that altered connectome organization may relate to the vulnerability to develop the disorder, but whether it relates to progression of illness after disease onset is currently unknown. Here, we examined the interaction between connectome structure and longitudinal changes in general functioning, clinical symptoms and IQ in the 3years following MRI assessment in a group of chronically ill schizophrenia patients. Effects in patients were compared to associations between connectome organization and changes in subclinical symptoms and IQ in healthy controls and unaffected siblings of schizophrenia patients. Analyzing the patient sample revealed a relationship between structural connectivity-particularly among central 'brain hubs'-and progressive changes in general functioning (p=0.007), suggesting that more prominent impairments of hub connectivity may herald future functional decline. Our findings further indicate that affected local connectome organization relates to longitudinal increases in overall PANSS symptoms (p=0.013) and decreases in total IQ (p=0.003), independent of baseline symptoms and IQ. No significant associations were observed in controls and siblings, suggesting that the findings in patients represent effects of ongoing illness, as opposed to normal time-related changes. In all, our findings suggest connectome structure to have predictive value for the course of illness in schizophrenia. PMID:25843919

    Full Text Available Abstract Background Chronic fatigue syndrome (CFS is a complex, multi-symptom illness with a multisystem pathogenesis involving alterations in the nervous, endocrine and immune systems. Abnormalities in stress responses have been identified as potential triggers or mediators of CFS symptoms. This study focused on the stress mediator neuropeptide Y (NPY. We hypothesized that NPY would be a useful biomarker for CFS. Methods The CFS patients (n = 93 were from the Chronic Fatigue and Related Disorders Clinic at the University of Miami and met the 1994 case definition of Fukuda and colleagues. Healthy sedentary controls (n = 100 were from NIH or VA funded studies. Another fatiguing, multi-symptom illness, Gulf War Illness (GWI, was also compared to CFS. We measured NPY in plasma using a radioimmunoassay (RIA. Psychometric measures, available for a subset of CFS patients included: Perceived Stress Scale, Profile of Mood States, ATQ Positive & Negative Self-Talk Scores, the COPE, the Beck Depression Inventory, Fatigue Symptom Inventory, Cognitive Capacity Screening Examination, Medical Outcomes Survey Short Form-36, and the Quality of Life Scale. Results Plasma NPY was elevated in CFS subjects, compared to controls (p = .000 and to GWI cases (p = .000. Receiver operating characteristics (ROC curve analyses indicated that the predictive ability of plasma NPY to distinguish CFS patients from healthy controls and from GWI was significantly better than chance alone. In 42 patients with CFS, plasma NPY had significant correlations ( Conclusions This study is the first in the CFS literature to report that plasma NPY is elevated compared to healthy controls and to a fatigued comparison group, GWI patients. The significant correlations of NPY with stress, negative mood, general health, depression and cognitive function strongly suggest that this peptide be considered as a biomarker to distinguish subsets of CFS.

    Full Text Available Background/Objective: find out whether any correlation exists between the degree and severity of symptoms as assessed by the SNOT-20 questionnaire and CT scan changes as graded by Lund-Mackay scoring system in chronic rhinosinusitis (CRS."nPatients and Methods: Fifties patients attending the otolaryngology department and diagnosed with CRS were prospectively entered in this study. All patients had their CT scans graded by using the Lund-Mackay  with the sino-nasal outcome questionnaire (SNOT-20. Correlation analysis was conducted to determine whether the CT scan stage as assigned by Lund Mackay staging system correlated with the SNOT-20 scores."nResults: The mean age of our patients was 32.4±8.5 and 32(64% of them were male and 18(36% were female. The mean SNOT-20 was 45±8.7 (29-67 and the mean Lund-Mackay sinus score was 18.5±5 (8- 24.The mean SNOT-20 score was higher for postnasal drip (PND and facial pain, and the lowest mean scores were for dizziness and ear pain. The Pearson's correlation coefficient confirmed that there was a good correlation between SNOT-20 scores and CT scores (Pearson correlation coefficient 0.77; P value, 0.0001."nConclusion: Patients with higher symptom scores are more likely to have CT imaging evidence of rhinosinusitis. In patients with isolated sleep or systematic symptoms, the likelihood of rhinosinusitis is less, even if symptoms are severe. Therefore, in these patients, sinus CT-scan should be considered before treatment to establish the diagnosis of chronic rhinosinusitis due to that a number of these patients may be doing not have rhinosinusitis.

    Full Text Available Objectives. To investigate the effect of the cause of acute respiratory failure and the role of comorbidities both acute and chronic on the outcome of COPD patients admitted to Respiratory Intensive Care Unit (RICU with acute respiratory failure and treated with NIV. Design. Observational prospective study. Patients and Methods. 176 COPD patients consecutively admitted to our RICU over a period of 3 years and treated with NIV were evaluated. In all patients demographic, clinical, and functional parameters were recorded including the cause of acute respiratory failure, SAPS II score, Charlson comorbidity index, and further comorbidities not listed in the Charlson index. NIV success was defined as clinical improvement leading to discharge to regular ward, while exitus or need for endotracheal intubation was considered failure. Results. NIV outcome was successful in 134 patients while 42 underwent failure. Univariate analysis showed significantly higher SAP II score, Charlson index, prevalence of pneumonia, and lower serum albumin level in the failure group. Multivariate analysis confirmed a significant predictive value for pneumonia and albumin. Conclusions. The most important determinants of NIV outcome in COPD patients are the presence of pneumonia and the level of serum albumin as an indicator of the patient nutritional status.

  4. Detection and differentiation of Mycoplasma gallisepticum and Mycoplasma synoviaeby PCR from tracheal swabs from birds with respiratory symptoms

    International Nuclear Information System (INIS)

    Mycoplasmas are worldwide pathogens that affect the poultry industry causing respiratory illness which cause a negative economic impact. Two mycoplasmas species are the most important in the commercial poultry: mycoplasma gallisepticum (MG) and mycoplasma synoviae (MS). By its importance and necessity to know and differentiate between mycoplasmas species in local's poultry houses this study used the PCR technique like a diagnosis tool, using tracheal swabs from bird with respiratory symptoms. A total of 91 samples from broilers, layers and breeders farms located in the departments of Cundinamarca and Boyaca was processed. The punctual prevalence founded in this study was 39.6 % for mg and 47.3 % for MS. statistical differences for type of production and positive samples for mg y MS (p < 0.05) were founded, a bigger number of positive samples from layers and breeder in comparison to broilers were found. In the same way, the positive samples for the layers and breeder from the age group between 20 and 60 weeks was greater, while for the broilers group most of the positive samples were from five weeks old birds for mg and two weeks old birds for MS.

    Florida red tides are naturally occurring blooms of the marine dinoflagellate, Karenia brevis. K. brevis produces natural toxins called brevetoxins. Brevetoxins become part of the marine aerosol as the fragile, unarmored cells are broken up by wave action. Inhalation of the aerosolized toxin results in upper and lower airway irritation. Symptoms of brevetoxin inhalation include: eye, nose, and throat irritation, coughing, wheezing, chest tightness, and shortness of breath. Asthmatics appear t...

    Noonan syndrome (NS) is a multiple malformation syndrome characterized by pulmonic stenosis, cardiomyopathy, short stature, lymphatic dysplasia, craniofacial anomalies, cryptorchidism, clotting disorders, and learning disabilities. Eight genes in the RAS/MAPK signaling pathway are implicated in NS. Chronic pain is an uncommon feature. To investigate the prevalence of pain in NS, we distributed a two-part questionnaire about pain among NS individuals at the Third International Meeting on Genetic Syndromes of the Ras/MAPK Pathway. The first part of the questionnaire queried demographic information among all NS participants. The second part was completed by individuals with chronic pain. Questions included musculoskeletal problems and clinical features of pain. Forty-five questionnaires were analyzed; 53% of subjects were female. Mean age was 17 (2-48) years; 47% had a PTPN11 mutation. Sixty-two percent (28/45) of individuals with NS experienced chronic pain. There was a significant relationship between prevalence of pain and residing in a cold climate (P = 0.004). Pain occurred commonly in extremities/joints and head/trunk, but more commonly in extremities/joints (P = 0.066). Subjects with hypermobile joints were more likely to have pain (P = 0.052). Human growth hormone treatment was not statistically significant among subjects without chronic pain (P = 0.607). We conclude that pain is a frequent and under-recognized clinical feature of NS. Chronic pain may be associated with joint hypermobility and aggravated by colder climate. Our study is a preliminary investigation that should raise awareness about pain as a common symptom in children and adults with NS. PMID:26297936

    Dose-response associations between respirable dust exposure and respiratory symptoms and between symptoms and spirometry outcomes among currently employed and formerly employed South-African coal miners were investigated. Work histories, interviews, and spirometry and cumulative exposure were assessed among 684 current and 212 ex-miners. Results: Lower prevalences of symptoms were found among employed compared with ex-miners. Associations with increasing exposure for symptoms of phlegm and past history of tuberculosis were observed, whereas other symptom prevalences were higher in the higher exposure categories. Symptomatic ex-miners exhibited lower lung-function compared to the nonsymptomatic. Compared with published data, symptoms rates were low in current miners but high in ex-miners. Although explanations could include the low prevalence of smoking and/or reporting/selection bias, a 'Survivor' and/or a 'hire' effect is more likely, resulting in an underestimation of the dust-related effect.

    The aim of this study is to compare the psychopathology and the quality of life of chronic daily headache patients between those with migraine headache and those with tension-type headache. We enrolled 106 adults with chronic daily headache (CDH) who consulted for the first time in specialised centres. The patients were classified according to the IHS 2004 criteria and the propositions of the Headache Classification Committee (2006) with a computed algorithm: 8 had chronic migraine (without medication overuse), 18 had chronic tension-type headache (without medication overuse), 80 had medication overuse headache and among them, 43 fulfilled the criteria for the sub-group of migraine (m) MOH, and 37 the subgroup for tension-type (tt) MOH. We tested five variables: MADRS global score, HAMA psychic and somatic sub-scales, SF-36 psychic, and somatic summary components. We compared patients with migraine symptoms (CM and mMOH) to those with tension-type symptoms (CTTH and ttMOH) and neutralised pain intensity with an ANCOVA which is a priori higher in the migraine group. We failed to find any difference between migraine and tension-type groups in the MADRS global score, the HAMA psychological sub-score and the SF36 physical component summary. The HAMA somatic anxiety subscale was higher in the migraine group than in the tension-type group (F(1,103) = 10.10, p = 0.001). The SF36 mental component summary was significantly worse in the migraine as compared with the tension-type subgroup (F(1,103) = 5.758, p = 0.018). In the four CDH subgroups, all the SF36 dimension scores except one (Physical Functioning) showed a more than 20 point difference from those seen in the adjusted historical controls. Furthermore, two sub-scores were significantly more affected in the migraine group as compared to the tension-type group, the physical health bodily pain (F(1,103) = 4.51, p = 0.036) and the mental health (F(1,103) = 8.17, p = 0.005).

    Full Text Available Background. HIV-infected subjects have an increased incidence of pulmonary emphysema. There are known gender differences in COPD phenotypic expression and diagnosis, but this is not well characterized in lung disease related to HIV. We analyzed a group at risk for the development of COPD (HIV-infected smokers to determine gender differences in pulmonary symptoms, pulmonary function tests, and HRCT appearances. Methods. This was a cross-sectional, baseline analysis of a prospective study performed between 2006 and 2010. We performed symptomatic, pulmonary function, and computed tomography assessments in 243 HIV-infected smokers. In a subset bronchoalveolar lavage was performed with proteomic analysis of their alveolar macrophages. Results. The majority of the participants were male 213 (87.6%. There was significantly higher percentage of cough and phlegm production in males. There was also a lower FEV1 and a higher RV in males than females. Proteomic analysis revealed 29 proteins with at least a 2-fold higher expression in males and 13 identified proteins that were higher in females. Conclusions. In this group of HIV-infected smokers, airway symptoms and pulmonary function test abnormalities were higher in men than women. These gender differences may be due to differential expression of certain proteins in this group.

  11. Prevalence of tuberculosis, HIV and respiratory symptoms in two Zambian communities: implications for tuberculosis control in the era of HIV.

    Directory of Open Access Journals (Sweden)

    Helen Ayles

    Full Text Available BACKGROUND: The Stop TB Partnership target for tuberculosis is to have reduced the prevalence of tuberculosis by 50% comparing 2015 to 1990. This target is challenging as few prevalence surveys have been conducted, especially in high burden tuberculosis and HIV countries. Current tuberculosis control strategies in high HIV prevalent settings are therefore based on limited epidemiological evidence and more evidence is needed from community-based surveys to inform improved policy formulation. METHODS AND FINDINGS: 8044 adults were sampled from 2 sub-districts (wards in Lusaka province, Zambia. Questionnaires were used to screen for symptoms, respiratory samples were obtained for culture and oral secretions collected for HIV testing. 79 individuals were found to have Mycobacterium tuberculosis in their sputum, giving an adjusted overall prevalence of tuberculosis of 870/100,000 (95% CI 570-1160/100,000. The adjusted overall prevalence of HIV was 28.61% (95% CI 26.04-31.19. HIV- infection was significantly associated with prevalent tuberculosis (Adj OR 2.3, 95% CI 1.42-3.74 and the population attributable fraction of HIV for prevalent tuberculosis was 36%. Symptoms such as prolonged cough (adj OR 12.72, 95% CI 7.05-22.94 and fever (Adj OR 2.04, 95%CI 1.23-3.39, were associated with prevalent tuberculosis, but 8 (10% individuals with prevalent tuberculosis denied having any symptoms at all and only 34 (43% would have been classified as a TB suspect by current guidelines. CONCLUSIONS: Undiagnosed tuberculosis is a challenge for tuberculosis control and new approaches are needed if we are to reach international targets. Epidemiological studies can inform screening algorithms for both detection and prevention of active tuberculosis.

    Full Text Available Asthma and chronic obstructive pulmonary disease (COPD are highly prevalent chronic diseases in the general population. Both are characterized by similar mechanisms: airway inflammation, airway obstruction, and airway hyperresponsiveness. However, the distinction between the two obstructive diseases is not always clear. Multiple epidemiological studies demonstrate that in elderly people with obstructive airway disease, as many as half or more may have overlapping diagnoses of asthma and COPD. A COPD-Asthma overlap syndrome is defined as an airflow obstruction that is not completely reversible, accompanied by symptoms and signs of increased obstruction reversibility. For the clinical identification of overlap syndrome COPD-Asthma Spanish guidelines proposed six diagnostic criteria. The major criteria include very positive bronchodilator test [increase in forced expiratory volume in one second (FEV1 ≥15% and ≥400 ml], eosinophilia in sputum, and personal history of asthma. The minor criteria include high total IgE, personal history of atopy and positive bronchodilator test (increase in FEV1 ≥12% and ≥200 ml on two or more occasions. The overlap syndrome COPD-Asthma is associated with enhanced response to inhaled corticosteroids due to the predominance of eosinophilic bronchial inflammation.The future clinical studies and multicenter clinical trials should lead to the investigation of disease mechanisms and simultaneous development of the novel treatment.

    The prevalence of neurobehavioral symptoms (NBS) and depression has been investigated in premenopausal rural women of West Bengal, India enrolled from arsenic (As) endemic (groundwater As 11-50 μg/L; n = 342) and control areas (As level ≤ 10 μg/L; n = 312). The subjective symptoms questionnaire and Beck's 21-point depression inventory-II were used for the detection of NBS and depression, respectively. Platelet P-selectin expression was measured by flow cytometry, plasma neurotransmitter activity with high performance liquid chromatography and groundwater As level by atomic absorption spectroscopy. The As level in groundwater was 2.72 ± 1.18 μg/L in control and 28.3 ± 13.51 μg/L in endemic areas (p memory (69.9 vs. 28.2%, p dopamine level was not significantly different (p>0.05) from that of controls. Moreover, women from endemic areas had 2.3-times more P-selectin-expressing platelets in their circulation (p < 0.001). After controlling the potential confounders, chronic low level As (11-50 μg/L) exposure showed a positive association with the prevalence of neurobehavioral symptoms and depression among Indian women in their child-bearing age.

    Long-term non-invasive positive pressure ventilation (NPPV) has widely been accepted to treat chronic hypercapnic respiratory failure arising from different etiologies. Although the survival benefits provided by long-term NPPV in individuals with restrictive thoracic disorders or stable, slowly-progressing neuromuscular disorders are overwhelming, the benefits provided by long-term NPPV in patients with chronic obstructive pulmonary disease (COPD) remain under question, due to a lack of convincing evidence in the literature. In addition, long-term NPPV reportedly failed in the classic trials to improve important physiological parameters such as arterial blood gases, which might serve as an explanation as to why long-term NPPV has not been shown to substantially impact on survival. However, high intensity NPPV (HI-NPPV) using controlled NPPV with the highest possible inspiratory pressures tolerated by the patient has recently been described as a new and promising approach that is well-tolerated and is also capable of improving important physiological parameters such as arterial blood gases and lung function. This clearly contrasts with the conventional approach of low-intensity NPPV (LI-NPPV) that uses considerably lower inspiratory pressures with assisted forms of NPPV. Importantly, HI-NPPV was very recently shown to be superior to LI-NPPV in terms of improved overnight blood gases, and was also better tolerated than LI-NPPV. Furthermore, HI-NPPV, but not LI-NPPV, improved dyspnea, lung function and disease-specific aspects of health-related quality of life. A recent study showed that long-term treatment with NPPV with increased ventilatory pressures that reduced hypercapnia was associated with significant and sustained improvements in overall mortality. Thus, long-term NPPV seems to offer important benefits in this patient group, but the treatment success might be dependent on effective ventilatory strategies. PMID:26418151

    Respiratory consequences of work in food processing industry were studied in 764 female workers exposed to organic dusts associated with the processing of green and roasted coffee, tea, spices, dried fruits, cocoa and flour. A group of 387 female workers not exposed to respiratory irritants served as controls for the prevalence of acute (during work shift) and chronic respiratory symptoms. A greater prevalence of all acute and chronic respiratory symptoms was consistently found among exposed workers than among control workers. The highest prevalence of chronic respiratory symptoms was recorded for chronic cough (40%), followed by acute symptoms of dry cough (58.7%). The difference in the prevalence of chronic respiratory symptoms between the exposed and control workers was in general significant (p DSCG) significantly diminished across-shift reductions for FEF50 and FEF25 in a subgroup of the examined workers. Our data suggested the female workers employed in food processing industry to be at risk of developing both acute and chronic respiratory symptoms as well as ventilatory capacity impairment as the result of occupational exposures.

  18. The possibility of evaluation on inflammatory change at respiratory tract in chronic bronchial asthma using 67Ga scintigraphy

    International Nuclear Information System (INIS)

    67Ga scintigraphy was performed in 17 patients with chronic bronchial asthma to grasp the inflammatory change of respiratory tract. On 67Ga scintigraphy, abnormal accumulations were detected on lung fields in 6 cases (35.3%) of 17 cases. In 5 cases of these 6 cases, the defect areas which were pointed out on 81mKr ventilation scintigraphy were matched to the abnormal accumulation areas which were pointed out on 67Ga scintigraphy. In dynamics, the abnormal accumulation areas which were pointed out on 67Ga scintigraphy were matched to the defect areas which had been at all times pointed out on 81mKr ventilation scintigraphy. 67Ga scintigraphy was expected to be one of index to grasp the inflammatory change of respiratory tract in patients with chronic bronchial asthma.

    Dagmar Elfriede Rinnenburger

    2012-01-01

    Full Text Available INTRODUCTION: The transition from paternalistic medicine to a healthcare culture centred on the patient's decision making autonomy presents problems of communication and understanding. Chronic respiratory failure challenges patients, their families and caregivers with important choices, such as invasive and non-invasive mechanical ventilation and tracheostomy, which, especially in the case of neuromuscular diseases, can significantly postpone the end of life. MATERIAL AND METHODS: A 7-item questionnaire was administered to 100 patients with advanced COPD, neuromuscular diseases and pulmonary fibrosis, all of them on oxygen therapy and receiving day-hospital treatment for respiratory failure. The objective was to find out whether or not patients, if faced with a deterioration of their health condition, would want to take part in the decision making process and, if so, how and with whom. RESULTS. Results showed that: 90% of patients wanted to be interviewed, 10% preferred not to be interviewed, 82% wanted to be regularly updated on their clinical situation, 75% wanted to be intubated, if necessary, and 56% would also agree to have a tracheostomy. These choices have been confirmed one year later, with 93% of respondents accepting the questionnaire and considering it useful. CONCLUSIONS: It is possible to conclude that a simple questionnaire can be a useful tool contributing to therapeutic decision making in respiratory failure.

    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.

    Sixteen adult patients suffering from severe chronic non-allergic rhinitis with nasal vasoconstrictor abuse for more than a year, received, under local anaesthesia, an intranasal spray of capsaicin (3.3 x 10(-3) mol), the pungent agent in hot pepper, once weekly for 5 weeks. The subjective intensity of their nasal obstruction, rhinorrhoea and sneezing frequency were evaluated throughout the study and the vascular effects of capsaicin on the nasal mucosa were recorded by anterior rhinomanometry and laser Doppler flowmetry. Calcitonin gene-related peptide (CGRP) is a vasodilator agent present in sensory nerves and may play a major role in the vascular component of neurogenic inflammation. Therefore, the nasal mucosa content of CGRP-like immunoreactivity (CGRP-LI) was determined by radioimmunoassay in biopsies obtained before and after the capsaicin treatment. Intra-nasal capsaicin application evoked a larger vascular response in patients with rhinitis than in controls (P less than 0.05). Both nasal vascular responses and subjective discomfort following capsaicin were markedly reduced after the fifth application (P less than 0.01). In parallel, a 50% reduction of the CGRP-LI content in the nasal biopsies was observed. All symptoms were significantly improved throughout a 6 month follow-up period. No significant side-effects occurred and weaning from nasal vasoconstrictor agents was possible. Both the subjective symptom score and objective measurements of vascular reactivity suggest that repeated intra-nasal capsaicin application could be beneficial for patients with chronic rhinitis, possibly by reducing hyperreactive nasal reflexes.

    Previous investigations have established that dancers suffer a large number of injuries to the lower leg, foot, and ankle, with a portion of these being significant time loss injuries or in some cases career ending. Lateral ankle sprain is a common injury in dancers and can often lead to recurrent instability and repetitive injuries. Research in other active populations has linked ankle sprains to the development of chronic ankle instability (CAI). Therefore, the purpose of this study was to identify the prevalence of CAI and related symptoms of ankle sprain in a student dance population. Individuals were included if they were currently a modern or ballet dance major at the investigators' university (exclusion criterion: a history of fracture or surgery in the lower extremities). A self-reported demographic questionnaire and the Identification of Functional Ankle Instability survey were used to identify the presence and characteristics of CAI. A total of 83 questionnaires were collected, and after exclusions, 77 participants remained: 43 modern dancers and 34 ballet dancers (10 males and 67 females, mean age 19.61 ± 2.53 years, mean dance experience 13.61 ± 3.16 years). Of all dancers surveyed, 41 (53.2%) had CAI, and of those 24 (58.5%) were modern dancers, and 17 (41.5%) were ballet dancers. When looking only at those dancers who had a previous lateral ankle sprain, 75.9% were identified as having CAI. Chronic Ankle Instability can create long-term problems for anyone but especially female dancers, who place extreme stress on their feet and ankles from being en pointe or demi-pointe. It is important to educate dancers, instructors, and medical staff of the importance of recognizing CAI and seeking medical care for ankle sprains and their residual symptoms. PMID:25474297

    Full Text Available Abstract Background Depression is predicted to become one of the two most burdensome diseases worldwide by 2020 and is common in people with chronic physical conditions. However, depression is relatively uncommon in Asia. Family support is an important Asian cultural value that we hypothesized could protect people with chronic physical conditions from developing depression. We investigated depressive symptom prevalence and risk factors in a Chinese sample with chronic medical conditions, focusing on the possible protective role of family relationships. Methods Data were obtained from the Hong Kong Jockey Club FAMILY Project cohort study in 2009–2011, which included 6,195 participants (age ≥15 with self-reported chronic conditions. Depressive symptoms were recorded using the Patient Health Questionnaire-9 (PHQ-9. Demographic and lifestyle variables, stressful life events, perceived family support and neighborhood cohesion were assessed. Factors associated with a non-somatic (PHQ-6 depression score were also examined. Results The prevalence of depressive symptoms (PHQ-9 scores ≥5 was 17% in those with one or more chronic conditions, and was more prevalent in women than in men (19.7% vs. 13.9%; p p p  Conclusions Acute life stress and the number of chronic conditions, together with socio-demographic factors, explain most variance in depressive symptoms among chronically ill Chinese individuals. Somatic items in the PHQ-9 increased the depression scores but they did not alter the pattern of predictors. Family support appears to be an important protective factor in Chinese cultures for individuals with chronic conditions.

    The neural pathogenic mechanisms involved in mediating chronic pain and whiplash associated disorders (WAD) after rear impact car collisions are largely unknown. This study's first objective was to compare resting state regional cerebral blood flow (rCBF) by means of positron emission tomography with (15)O labelled water in 21 WAD patients with 18 healthy, pain-free controls. A second objective was to investigate the relations between brain areas with altered rCBF to pain experience, somatic symptoms, posttraumatic stress symptoms and personality traits in the patient group. Patients had heightened resting rCBF bilaterally in the posterior parahippocampal and the posterior cingulate gyri, in the right thalamus and the right medial prefrontal gyrus as well as lowered tempero-occipital blood flow compared with healthy controls. The altered rCBF in the patient group was correlated to neck disability ratings. We thus suggest an involvement of the posterior cingulate, parahippocampal and medial prefrontal gyri in WAD and speculate that alterations in the resting state are linked to an increased self-relevant evaluation of pain and stress.

    Full Text Available Introduction Chronic low back pain is a degenerative rheumatic disease and is characterized by various symptoms and clinical signs. Balneotherapy Balneotherapy represents a therapy by various hot or warm baths in natural mineral waters of specific physical and chemical characteristics. When used externally, they have mechanical, chemical and thermic effects. Balneotherapy of lumbar syndrome includes: individual baths, swimming in the pool, hydrokinesitherapy, underwater massage, underwater extension, mud therapy, mud baths. The therapy should be closely monitored for optimal efficacy and it is necessary to examine: functional status of the lumbosacral region, general functional status (level of activity, lower extremities, pain measurement, use of non-steroid anti-rheumatic and analgesic agents. In order to follow-up the effects of therapy and establish the prognosis it is important to perform: detailed anamnesis, anthropometrics measurements, socio-epidemiological research, clinical examinations. Conclusion Lumbar syndrome is usually caused by a degenerative disease of the spinal column. More than 25% of people under 45 years of age are unable to work due to chronic low back pain. That is why preventive measures, prompt diagnosis and adequate therapy are of utmost importance.

    The purpose of this work was to assess the relation between exposure to secondhand smoke (SHS) at work and reported respiratory and sensory symptoms. A cross-sectional telephone survey of 382 nonsmoking indoor workers in Victoria, Australia was used. After controlling for potential confounders, exposure to SHS at work for part of the day was significantly associated with an increased risk of wheeze (OR = 4.26), frequent cough (OR = 2.26), sore eyes (OR = 3.77), and sore throat (OR = 2.70). Among workers who had not experienced a cold in the past 4 weeks, we found strong dose-response relationships between increasing levels of exposure to SHS at work and morning cough, frequent cough, sore eyes and sore throat, and a positive relationship for wheeze. These findings provide compelling evidence that nonsmoking indoor workers are adversely affected by exposure to SHS at work and underline the importance of workplace smoke-free policies in protecting the health of workers.

    branch density was similar in the two groups (114.0 ± 92.4 vs 118.1 ± 55.9 branches/mm2, P < .864). Tortuosity coefficient and log tortuosity coefficient also were similar in the chronic migraine and control groups. All migraine subjects had symptoms consistent with a diagnosis of dry eye syndrome. Conclusions We found that in the sample used in this study, the presence of structural changes in nociceptive corneal axons lends further support to the hypothesis that the trigeminal system plays a critical role in the pathogenesis of migraine. In vivo corneal confocal microscopy holds promise as a biomarker for future migraine research as well as for studies examining alterations of corneal innervation. Dry eye symptoms appear to be extremely prevalent in this population. The interrelationships between migraine, corneal nerve architecture, and dry eye will be the subject of future investigations.

    2016-06-01

    Chronic respiratory diseases (CRDs) affect hundreds of millions of people. The United Nations 2011 meeting on non-communicable diseases (NCDs) marked a turning point in addressing this burden. The targets established following this meeting incorporated specific measures to address the availability and affordability of essential medicines. These are aligned with the sustainable development goals (SDGs) and the push for universal health coverage. However, essential medicines for CRDs remain unaffordable and unavailable to many. For asthma, the availability of medicines was respectively 30.1% and 43.1% in the public and private sectors. The maximum annual costs of treatment were US$102.10 for beclometasone, US$82.99 for salbutamol and US$1501.79 for budesonide, representing respectively 40%, 15% and 209% of per capita income in Malawi, Burkina Faso and Guinea. Multiple factors contribute to poor availability and affordability. Experience from human immunodeficiency virus/acquired immune-deficiency syndrome shows that medicines and care can be delivered in low-income countries and among the NCDs. A unique example of an effective mechanism for providing access to affordable essential CRD medicines is the Asthma Drug Facility. Working on the six health system building blocks proposed by the World Health Organization can help countries address not only problems regarding access to medicines, but also those hampering adequate care. Improving medicine supply systems, training, national guidelines, financing, research, data utilisation and models of care at the primary health care level will help. A CRD target (e.g., 50% reduction in asthma hospitalisations) as well as the use of asthma as a measure for health system effectiveness and CRDs as a tracer for SDGs would help focus global, national and local leadership.

  18. Clinical and Laboratory Findings in Patients With Acute Respiratory Symptoms That Suggest the Necessity of Chest X-ray for Community-Acquired Pneumonia

    International Nuclear Information System (INIS)

    Pneumonia is a common illness in all parts of the world and is considered as a major cause of death among all age groups. Nevertheless, only about 5% of patients referring to their primary care physicians with acute respiratory symptoms will develop pneumonia. This study was performed to derive practical criteria for performing chest radiographs for the evaluation of community-acquired pneumonia (CAP). A total of 420 patients with acute respiratory symptoms and positive findings on chest radiograph were evaluated from December 2008 to December 2009. The subjects were referred to outpatient clinics or emergency departments of Birjand's medical university hospitals, Iran, and were enrolled as positive cases. A checklist was completed for each patient including their demographic information, clinical signs and symptoms (cough, sputum production, dyspnea, chest pain, fever, tachycardia, and tachypnea), abnormal findings in pulmonary auscultation and laboratory findings (erythrocyte sedimentation rate, C-reactive protein levels, and white blood cell count). An equal number of age-matched individuals with acute respiratory symptoms, but insignificant findings on chest radiography, were included as the control group. Finally, the diagnostic values of different findings were compared. The data showed that vital signs and physical examination findings are useful screening parameters for predicting chest radiograph findings in outpatient settings. Therefore, by implementing a prediction rule, we would be able to determine which patients would benefit from a chest X-Ray (sensitivity, 94% and specificity, 57%). This study's findings suggest that requesting chest radiographs might not be necessary in patients with acute respiratory symptoms unless the vital signs and/or physical examination findings are abnormal. Considering the 94% sensitivity of this rule for predicting CAP, a chest radiograph is required for patients with unreliable follow-ups or moderate to high

    Full Text Available BACKGROUND: Measurements of Energy Expenditure (EE at rest (REE and during physical activities are increasing in interest in chronic patients. In this study we aimed at evaluating the validity/reliability of the SenseWear®Armband (SWA device in terms of REE and EE during assisted walking in Chronic Respiratory Failure (CRF patients receiving long-term oxygen therapy (LTOT. METHODOLOGY/PRINCIPAL FINDINGS: In a two-phase prospective protocol we studied 40 severe patients and 35 age-matched healthy controls. In phase-1 we determined the validity and repeatability of REE measured by SWA (REEa in comparison with standard calorimetry (REEc. In phase-2 we then assessed EE and Metabolic Equivalents-METs by SWA during the 6-minute walking test while breathing oxygen in both assisted (Aid or unassisted (No-Aid modalities. When compared with REEc, REEa was slightly lower in patients (1351±169 vs 1413±194 kcal/day respectively, p<0.05, and less repeatable than in healthy controls (0.14 and 0.43 coefficient respectively. COPD patients with CRF patients reported a significant gain with Aid as compared with No-Aid modality in terms of meters walked, perceived symptoms and EE. CONCLUSIONS/SIGNIFICANCE: SWA provides a feasible and valid method to assess the energy expenditure in CRF patients on LTOT, and it shows that aided walking results in a substantial energy saving in this population.

    Full Text Available The relationship between exposure to traffic induced particles, respiratory health and cardiac diseases was studied in the RHINE Tartu cohort. A postal questionnaire with commonly used questions regarding respiratory symptoms, cardiac disease, lifestyle issues such as smoking habits, indoor environment, occupation, early life exposure and sleep disorders was sent to 2,460 adults. The annual concentrations of local traffic induced particles were modelled with an atmospheric dispersion model with traffic flow data, and obtained PMexhaust concentrations in 40 × 40 m grids were linked with home addresses with GIS. The relationship between the level of exhaust particles outside home and self-reported health problems were analyzed using a multiple logistic regression model. We found a significant relation between fine exhaust particles and cardiac disease, OR = 1.64 (95% CI 1.12–2.43 for increase in PMexhaust corresponding to the fifth to the 95th percentile range. The associations also were positive but non-significant for hypertension OR = 1.42 (95% CI 0.94–2.13, shortness of breath OR = 1.27 (95% CI 0.84–1.94 and other respiratory symptoms.

    2001-12-01

    A study was undertaken to investigate the occurrence of ovine lentivirus (OvLV) infection in sheep with chronic respiratory disease on the Laikipia Plateau, Kenya. All seven Merino crossbred sheep with chronic dyspnoea and emaciation examined for gross and microscopic lesions had lymphoid interstitial pneumonia (LIP), and one also had pulmonary abscesses. Two of the sheep with LIP also had lesions of ovine pulmonary carcinoma (OPC, jaagsiekte). Using in situ hybridization, OvLV DNA localized to a high proportion of pulmonary macrophages in lungs with lesions of LIP. Lung tissue samples from six of these sheep were positive for a syncytium-inducing virus in cultures of lamb testis cells. Thin-section electron microscopy of infected cells showed virions with morphogenesis typical of lentiviruses. In a western blotting assay, monoclonal antibodies to the OvLV capsid (CA, p27) and matrix (MA, p15) proteins of a North American OvLV isolate reacted with similar-sized bands of the virus, and serum from six of the sheep were reactive with CA from the Kenyan viral isolate. Using an OvLV agar gel immunodiffusion (AGID) test, all seven sheep were positive for serum antiviral antibody, as were 29% of 63 clinically normal sheep from Laikipia District. However, when sera from the healthy sheep were tested in a western blot assay, only 52% had IgG reactive to the OvLV CA, indicating a high rate of false negative reactions with the AGID test. Serum samples from 87 Red Maasai or Dorper crossbred sheep from two farms in other parts of Kenya were OvLV seronegative by both the AGID test and the western blot assay. These results document the first identification of OvLV as a cause of chronic respiratory disease in sheep in Kenya and show a high rate of infection in sheep flocks, with a high prevalence of chronic respiratory disease.

    Full Text Available The purpose of the work was to determine the consequence of pathomorphological changes of the respiratory part and surfactant system of lungs at hepatic insufficiency, and also to estimate the dynamics of changes of both compensate and decompensate types in experimental model. 88 mature rats both sexes for modeling of the hepatic insufficiency by the Саmегоn’s method were used. Rat lungs were examined in 2, 4, 8 and 16 weeks after beginning of experiment. The increase of the volume of regions with emphysema, dysthelectasis and athelectasis at in the respiratory portion of the lungs were found. The increase of interstitial components with decreasing of relative thickness of epithelial layer of alveoli and the endothelial cells in capillaries were observed in aero-hematic barrier. The increase of vessel permeability, formation of hemorrhages, dysthelectasis and athelectasis are observed in the respiratory portion at chronic hepatic insufficiency. The sclerotic changes in the interalveolar septa with pneumofibrosis are determined in the terminal stages of chronic endotoxicosis.

    2006-07-01

    In 1991, Neas et al. reported that indoor nitrogen dioxide (NO(2)), a byproduct of high-temperature combustion, was significantly associated with lower respiratory symptoms among a cohort of 1,159 white children aged 7-11 years in six US cities studied from 1983 to 1988. For each 15 p.p.b. increment of NO(2), the multivariate adjusted odds ratio (OR) was 1.4 (95% confidence interval (CI)=[1.1, 1.7]). Although indoor NO(2) concentration in the ambient air was assessed only in a subset of the children, the prevalence of lower respiratory symptoms and surrogate exposure variables were available in all of the children at the time of the indoor monitoring program. This paper evaluates the effect of indoor NO(2) exposure on the annual risk of lower respiratory symptoms by applying a regression calibration method to the 2,891 children in the overall study with complete covariate and outcome data, 1,137 of whom had NO(2) directly measured and 1,754 of whom only surrogate exposure data were available. An estimate of the indoor annual NO(2) exposure effect (p.p.b.) is obtained, which is adjusted for measurement error induced by the use of surrogate NO(2) sources among the 1,754. These sources include the presence of a gas stove with or without a pilot light, the presence of a kerosene space heater, the presence of a wood stove, and the usage of a stove for heating, and residential characteristics, including fan usage for kitchen ventilation and the total number of rooms in the home. After adjusting for age, gender, city, parental history of respiratory diseases, and smoking inside the children's home (packs/day), a 15-p.p.b. increment in NO(2) exposure was found to be associated with a significant 50% increased annual risk of lower respiratory symptoms (OR=1.5, 95% CI=[1.2, 1.8]). Simulation results indicated that, under conditions similar to those observed in these data, the estimator is unbiased and has a coverage probability close to the nominal value. Using the

    2005-02-01

    Full Text Available Abstract Background The high rate of antibiotic prescriptions general practitioners (GPs make for respiratory tract infections (RTI are often explained by non-medical reasons e.g. an effort to meet patient expectations. Additionally, it is known that GPs to some extent believe in the necessity of antibiotic treatment in patients with assumed bacterial infections and therefore attempt to distinguish between viral and bacterial infections by history taking and physical examination. The influence of patient complaints and physical examination findings on GPs' prescribing behaviour was mostly investigated by indirect methods such as questionnaires. Methods Direct, structured observation during a winter "cough an cold period" in 30 (single handed general practices. All 273 patients with symptoms of RTI (age above 14, median 37 years, 51% female were included. Results The most frequent diagnoses were 'uncomplicated upper RTI/common cold' (43% followed by 'bronchitis' (26%. On average, 1.8 (95%-confidence interval (CI: 1.7–2.0 medicines per patient were prescribed (cough-and-cold preparations in 88% of the patients, antibiotics in 49%. Medical predictors of antibiotic prescribing were pathological findings in physical examination such as coated tonsils (odds ratio (OR 15.4, 95%-CI: 3.6–66.2 and unspecific symptoms like fatigue (OR 3.1, 95%-CI 1.4–6.7, fever (OR 2.2, 95%-CI: 1.1–4.5 and yellow sputum (OR 2.1, 95%-CI: 1.1–4.1. Analysed predictors explained 70% of the variance of antibiotic prescribing (R2 = 0,696. Efforts to reduce antibiotic prescribing, e.g. recommendations for self-medication, counselling on home remedies or delayed antibiotic prescribing were rare. Conclusions Patient complaints and pathological results in physical examination were strong predictors of antibiotic prescribing. Efforts to reduce antibiotic prescribing should account for GPs' beliefs in those (non evidence based predictors. The method of direct observation was

    Full Text Available Background: The protease-antiprotease hypothesis proposes that inflammatory cells and oxidative stress in chronic obstructive pulmonary disease (COPD produce increased levels of proteolytic enzymes (neutrophil elastase, matrix metalloproteinases [MMP] which contribute to destruction of parenchyma resulting in progressive decline in forced expiratory volume in one second. Doxycycline, a tetracycline analogue, possesses anti-inflammatory properties and inhibits MMP enzymes. Objectives: To assess the effect of 4 weeks doxycycline in a dose of 100 mg once a day in patients of moderate to severe COPD with stable symptoms. Methods : In an interventional, randomized, observer-masked, parallel study design, the effect of doxycycline (100 mg once a day for 4 weeks was assessed in patients of COPD having stable symptoms after a run-in period of 4 weeks. The study participants in reference group did not receive doxycycline. The parameters were pulmonary functions, systemic inflammation marker C-reactive protein (CRP, and medical research council (MRC dyspnea scale. Use of systemic corticosteroids or antimicrobial agents was not allowed during the study period. Results: A total of 61 patients completed the study (31 patients in doxycycline group and 30 patients in reference group. At 4 weeks, the pulmonary functions significantly improved in doxycycline group and the mean reduction in baseline serum CRP was significantly greater in doxycycline group as compared with reference group. There was no significant improvement in MRC dyspnea scale in both groups at 4 weeks. Conclusion: The anti-inflammatory and MMP-inhibiting property of doxycycline might have contributed to the improvement of parameters in this study.

    Full Text Available BACKGROUND: Pulmonary rehabilitation is a common type of complex treatment especially in patients with chronic obstructive pulmonary disease (COPD. By contrast, only few rehabilitation centres in the Czech Republic provide pulmonary rehabilitation programme to non-COPD patients. OBJECTIVE: To find out if the rehabilitation programme has a similar effect in patient with obstructive and restrictive ventilatory disorder. METHODS: Twenty-eight patients with either COPD or pulmonary sarcoidosis (PS have been enrolled for the 6-week rehabilitation programme. Lung functions, maximal inspiratory (MIP and expiratory (MEP mouth pressures, chest expansion at the level of the 4th intercostal space (IC and at the level of the xiphoid process (XP, six-minute walk test, health-related quality of life using the St. George’s Questionnaire (SGRQ and fatigue occurrence using the Multidimensional Assessment of Fatigue scale (MAF were tested at the baseline and after 6 weeks. The rehabilitation programme consisted of exercise training, ventilatory muscle training, respiratory physiotherapy and soft-tissue techniques. RESULTS: Patients with COPD improved significantly (p < .05 in MIP by 17% (10.5 cm H2O, MEP by 18% (16.8 cm H2O, IC by 65% (1.7 cm, XP by 90% (1.9 cm, six-minute walk distance (6MWD by 15% (64.1 m and SGRQ by –28% (–12.3 points. Patients with PS improved significantly (p < .05 in MIP by 25% (20.1 cm H2O, IC by 29% (1.3 cm, XP by 29% (1.3 cm and 6MWD by 6% (31.6 m. The change in lung functions and MAF in both groups; MEP and SGRQ in PS group were insignificant after the 6-week rehabilitation programme. CONCLUSIONS: The 6-week rehabilitation programme produces similar responses in functional health status of patients with either obstructive or restrictive ventilatory disorder. However, patients with restrictive ventilatory disorder in particular should be encouraged to continue in the programme to enhance the health

    This longitudinal study examined the prospective contribution of respiratory sinus arrhythmia (RSA), a key physiological indicator of self-regulation, to eating disorder symptoms in college students, and whether this link was moderated by maladaptive responses to stress and parent psychological control. At Wave 1, college students' RSA was measured at rest. At Waves 1 and 2 (six-month follow-up), students reported on their eating disorder symptoms, coping and involuntary responses to stress, and perceptions of their parents' use of psychological control. Significant three-way interactions indicated that the link between RSA and subsequent eating disorder symptoms was contingent on responses to stress and parent psychological control. In the context of maladaptive responses to stress and high psychological control, RSA predicted increased eating disorder symptoms over time. In the absence of parent psychological control, high RSA was beneficial in most cases, even when individuals reported maladaptive responses to stress. This study presents novel evidence that high RSA contributes to risk for or resilience to eating disorder symptoms over time. RSA can be protective against eating disorder symptoms, but in some contexts, the self-regulation resources that high RSA provides may be inappropriately applied to eating cognitions and behaviors. This research highlights the importance of examining physiological functioning conjointly with other risk factors as precursors to eating disorder symptoms over time. PMID:26826976

    Full Text Available Abstract Background Chocolate is rich in flavonoids that have been shown to be of benefit in disparate conditions including cardiovascular disease and cancer. The effect of polyphenol rich chocolate in subjects with chronic fatigue syndrome (CFS has not been studied previously. Methods We conducted a double blinded, randomised, clinical pilot crossover study comparing high cocoa liquor/polyphenol rich chocolate (HCL/PR in comparison to simulated iso-calorific chocolate (cocoa liquor free/low polyphenols(CLF/LP on fatigue and residual function in subjects with chronic fatigue syndrome. Subjects with CFS having severe fatigue of at least 10 out of 11 on the Chalder Fatigue Scale were enrolled. Subjects had either 8 weeks of intervention in the form of HCL/PR or CLF/LP, with a 2 week wash out period followed by 8 weeks of intervention with the other chocolate. Results Ten subjects were enrolled in the study. The Chalder Fatigue Scale score improved significantly after 8 weeks of the HCL/PR chocolate arm [median (range Exact Sig. (2-tailed] [33 (25 - 38 vs. 21.5 (6 - 35 0.01], but that deteriorated significantly when subjects were given simulated iso-calorific chocolate (CLF/CP [ 28.5 (17 - 20 vs. 34.5 (13-26 0.03]. The residual function, as assessed by the London Handicap scale, also improved significantly after the HCL/PR arm [0.49 (0.33 - 0.62 vs. 0.64 (0.44 - 0.83 0.01] and deteriorated after iso-calorific chocolate [00.44 (0.43 - 0.68 vs. 0.36 (0.33 - 0.620.03]. Likewise the Hospital Anxiety and Depression score also improved after the HCL/PR arm, but deteriorated after CLF/CP. Mean weight remained unchanged throughout the trial. Conclusion This study suggests that HCL/PR chocolate may improve symptoms in subjects with chronic fatigue syndrome.

    2016-01-01

    Background Thyroid autoimmunity has been increasingly reported to be associated with chronic urticaria (CU), and the possible clinical benefit of thyroid hormone or anti-thyroid drugs in some CU patients with autoimmune thyroid disease has been studied. However, the effect of thyroid hormone or anti-thyroid drugs on clinical symptoms of CU remains unclear. Objective We investigated the clinical response of urticaria to the treatment of thyroid dysfunction. Methods Medical records of patients with CU evaluated for thyroid autoimmunity and thyroid function were collected and reviewed. Results Of 184 patients with CU, 43 patients (23.4%) had thyroid autoantibodies and 26 patients (14.1%) had thyroid dysfunction. While none of the five patients with Graves' disease showed any improvement of urticaria after treatment with anti-thyroid drugs, two of the 10 patients with Hashimoto's thyroiditis showed improved urticaria after being treated with levothyroxine. Conclusion Although levothyroxine treatment was effective in a minority of patients with CU, there may be a causal relationship between CU and thyroid autoimmunity. PMID:27081267

    The objective of this study was to examine the feasibility of a full-scale investigation of the neurophysiological mechanisms of COPD-induced respiratory neuromuscular control deficits. Characterization of respiratory single- and multi-muscle activation patterns using surface electromyography (sEMG) were assessed along with functional measures at baseline and following 21±2 (mean±SD) sessions of respiratory motor training (RMT) performed during a one-month period in four patients with GOLD stage II or III COPD. Pre-training, the individuals with COPD showed significantly increased (p<0.05) overall respiratory muscle activity and disorganized multi-muscle activation patterns in association with lowered spirometrical measures and decreased fast- and slow-twitch fiber activity as compared to healthy controls (N=4). Following RMT, functional and respiratory sEMG activation outcomes during quite breathing and forced expiratory efforts were improved suggesting that functional improvements, induced by task-specific RMT, are evidence respiratory neuromuscular networks re-organization.

    Abstract Idiopathic chronic eosinophilic pneumonia (ICEP) is characterized by subacute or chronic respiratory and general symptoms, alveolar and/or blood eosinophilia, and peripheral pulmonary infiltrates on chest imaging. Eosinophilia is present in most cases, usually in excess of 1000/mm3. In absence of significant blood eosinophilia, a diagnosis of ICEP is supported by the demonstration of bronchoalveolar lavage eosinophilia. ICEP is typically associated with eosinophil counts higher than ...

    Upper gastrointestinal tract (GIT) symptoms are not disease specific and of limited value in the differentiation of GIT disorders. The present study aimed to determine the etiology of chronic unspecific symptoms in children and to test the need for upper endoscopy in diagnosis. This is a prospective study for 30 Egyptian children presented with chronic upper GIT symptoms for at least 2 months. History regarding severity and frequency of GIT symptoms were asked for. Children with known disorder that explains presenting symptoms were excluded. Upper GIT endoscopy wa performed and 5 biopsies were obtained for pathological examination and for Hpylori testing. The results showed that children age ranged between 2.5-18 years with mean ± SD of 13.6 ± 3.4 and 63.3% were females. The main complaints were epigastric pain in 43.3%, hematemesis in 30% and vomiting in 26.7%. Motility disorders were diagnosed in 66.7% children; in the form of GERD in 63.3% and achalasia in one. Complication of GERD in the form of erosive esophagitis was present in 15.8% children, while Barrett's esophagus was not observed. H. pylori infection was diagnosed in 80% histologically. Eosinophilic esophagitis was not detected. PMID:27363051

    Chronic respiratory diseases often cause impairment in the functions and/or structure of the respiratory system, and impose limitations on different activities in the lives of persons who suffer them. In younger patients with an active working life, these limitations can cause problems in carrying out their normal work. Article 41 of the Spanish Constitution states that «the public authorities shall maintain a public Social Security system for all citizens guaranteeing adequate social assistance and benefits in situations of hardship». Within this framework is the assessment of fitness for work, as a dual-nature process (medico-legal) that aims to determine whether it is appropriate or not to recognise a person's right to receive benefits which replace the income that they no longer receive as they cannot carry out their work, due to loss of health. The role of the pulmonologist is essential in evaluating the diagnosis, treatment, prognosis and functional capacity of respiratory patients. These recommendations seek to bring the complex setting of fitness for work evaluation to pulmonologists and thoracic surgeons, providing action guidelines that allow them to advise their own patients about their incorporation into working life.

    Abstract This study aims to evaluate the acute effects of an oscillating positive expiratory pressure device (flutter) on airways resistance in patients with chronic obstructive pulmonary disease (COPD). Randomized crossover study: 15 COPD outpatients from Asthma Lab–Royal Brompton Hospital underwent spirometry, impulse oscillometry (IOS) for respiratory resistance (R) and reactance (X), and fraction exhaled nitric oxide (FeNO) measures. Thirty minutes of flutter exercises: a “flutter-sham” procedure was used as a control, and airway responses after a short-acting bronchodilator were also assessed. Respiratory system resistance (R): in COPD patients an increase in X5insp (−0.21 to −0.33 kPa/L/s) and Fres (24.95 to 26.16 Hz) occurred immediately after flutter exercises without bronchodilator. Following 20 min of rest, a decrease in the R5, ΔR5, R20, X5, and Ax was observed, with R5, R20, and X5 values lower than baseline, with a moderate effect size; there were no changes in FeNO levels or spirometry. The use of flutter can decrease the respiratory system resistance and reactance and expiratory flow limitation in stable COPD patients with small amounts of secretions. PMID:26496331

  1. Respiratory Consequences of Mild-to-Moderate Obesity: Impact on Exercise Performance in Health and in Chronic Obstructive Pulmonary Disease

    Full Text Available In many parts of the world, the prevalence of obesity is increasing at an alarming rate. The association between obesity, multiple comorbidities, and increased mortality is now firmly established in many epidemiological studies. However, the link between obesity and exercise intolerance is less well studied and is the focus of this paper. Although exercise limitation is likely to be multifactorial in obesity, it is widely believed that the respiratory mechanical constraints and the attendant dyspnea are important contributors. In this paper, we examined the evidence that critical ventilatory constraint is a proximate source of exercise limitation in individuals with mild-to-moderate obesity. We first reviewed existing information on exercise performance, including ventilatory and perceptual response patterns, in obese individuals who are otherwise healthy. We then considered the impact of obesity in patients with preexisting respiratory mechanical abnormalities due to chronic obstructive pulmonary disease (COPD, with particular reference to the effect on dyspnea and exercise performance. Our main conclusion, based on the existing and rather sparse literature on the subject, is that abnormalities of dynamic respiratory mechanics are not likely to be the dominant source of dyspnea and exercise intolerance in otherwise healthy individuals or in patients with COPD with mild-to-moderate obesity.

    [Purpose] To investigate the effects of intensive aerobic exercise on respiratory capacity and walking ability in chronic stroke patients. [Subjects and Methods] The subjects were randomly assigned to an experimental group (n=6) or a control group (n=6). Patients in the experimental group received intensive aerobic exercise for 30 minutes and traditional physical therapy once a day, five days a week, for four weeks. The control group received aerobic exercise for 30 minutes and traditional physical therapy for 30 minutes a day, five days a week, for four weeks. [Results] After the intervention, both groups showed significant improvements in the forced vital capacity, forced expiratory volume in one second, 10-meter walking test, and six-minute walking test over the baseline results. The comparison of the two groups after the intervention revealed that the experimental group showed more significant improvements in the forced vital capacity, forced expiratory volume in one second, and six-minute walking test. There was no significant difference in saturation pulse oximetry oxygen and 10-meter walking test between the groups. [Conclusion] The results of this study suggest that intensive aerobic exercise has a positive effect on respiratory capacity and walking endurance in patients with chronic stroke.

    BACKGROUND Haemophilus species are the most common microbiota in humans. The aim of this paper was to investigate Haemophilus spp., mainly H. parainfluenzae prevalence, in the upper respiratory tract of chronic hepatitis C (CHC-positive) patients with or without therapy using pegylated interferon alfa and ribavirin. MATERIAL AND METHODS We collected 462 samples from 54 healthy people and 100 CHC-positive patients at various stages: before (group A), during (group B), and after (group C) antiviral therapy. Identification of bacterial isolates including biotypes and antimicrobials susceptibility was accomplished by means of standard microbiological methods. RESULTS In 70.4% of healthy people (control group) and in 27.0% of CHC-positive patients, the presence of haemophili, mainly H. parainfluenzae was observed, and those differences were statistically significant (p<0.0001). Statistically significant differences in Haemophilus spp. colonization were also observed among healthy people and CHC-positive patients from group A (p=0.0012) and from B or C groups (p<0.0001). Resistance to ampicillin in beta-lactamase-positive isolates and multidrug resistance (MDR) of H. parainfluenzae was detected mainly in group A. CONCLUSIONS The obtained data suggest that chronic hepatitis C, together with antiviral therapy, may influence the respiratory tract microbiota composition as found using haemophili, mainly H. parainfluenzae.

    Full Text Available The aetiology behind odor-related chronic somatic symptoms (O-RCSS is unknown, although both immunological and psychiatric causes have been suggested. The aim of this study was to investigate the occurrence of self-reported asthma and hay fever and psychiatric symptoms in individuals having O-RCSS compared to individuals with similar chronic somatic symptoms (CSS which were not odors-related, and also compared to healthy controls. Data from the Hordaland Health Study were used. 13,799 individuals, 40-45 years, answered a questionnaire including 16 questions related to somatic symptoms. They also indicated if the symptoms were odor-related, and answered questions about asthma and hay fever. Anxiety and depression were measured with the Hospital Anxiety and Depression Scale. 38 (0.6% men and 106 (1.4% women had O-RCSS, whereas 88 (1.5% men and 192 (2.5% women had CSS. Adjusted logistic regression analyses showed increased odds of self-reported asthma in those with O-RCSS compared to those with CSS (males: 3.81, 1.06-13.8, females: 2.60, 1.05-6.93 and compared to male and female controls (3.56, 1.89-6.68 and 4.81, 1.92-12.1 respectively. Increased odds of self-reported hay fever were in addition seen in females with O-RCSS. There were no differences in psychiatric symptoms between individuals with O-RCSS and CSS, although individuals in both groups showed increased odds compared to male and female controls. Increased occurrence of self-reported asthma was exclusively found among male and females with O-RCSS, compared to CSS and controls. Increased occurrence of psychiatric symptoms was seen both in individuals with O-RCSS and CSS.

    Patients with cystic fibrosis (CF) often suffer chronic lung infection with concomitant inflammation, a setting that may reduce the efficacy of gene transfer. While gene therapy development for CF often involves viral-based vectors, little is known about gene transfer in the context of an infected airway. In this study, three mouse models were established to evaluate adeno-associated virus (AAV) gene transfer in such an environment. Bordetella bronchiseptica RB50 was used in a chronic, nonlethal respiratory infection in C57BL/6 mice. An inoculum of ∼10(5) CFU allowed B. bronchiseptica RB50 to persist in the upper and lower respiratory tracts for at least 21 days. In this infection model, administration of an AAV vector on day 2 resulted in 2.8-fold reduction of reporter gene expression compared with that observed in uninfected controls. Postponement of AAV administration to day 14 resulted in an even greater (eightfold) reduction of reporter gene expression, when compared with uninfected controls. In another infection model, Pseudomonas aeruginosa PAO1 was used to infect surfactant protein D (SP-D) or surfactant protein A (SP-A) knockout (KO) mice. With an inoculum of ∼10(5) CFU, infection persisted for 2 days in the nasal cavity of either mouse model. Reporter gene expression was approximately ∼2.5-fold lower compared with uninfected mice. In the SP-D KO model, postponement of AAV administration to day 9 postinfection resulted in only a two fold reduction in reporter gene expression, when compared with expression seen in uninfected controls. These results confirm that respiratory infections, both ongoing and recently resolved, decrease the efficacy of AAV-mediated gene transfer. PMID:25144316

    Pulmonary function tests were done and compared to current and past potential exposure levels of toluene diisocyanate (TDI) for 57 TDI manufacturing workers and 89 workers not exposed to TDI or other known respiratory hazards. The average TDI plant experience was 4.1 years (standard deviation = 2.8). Routine industrial hygiene measurements have shown TDI exposure below a time-weighted average of 0.005 parts per million and a short-term exposure level of 0.02 parts per million. A certified industrial hygienist ranked department and job classification by level of potential exposure to TDI (none, low, moderate, and high). A questionnaire was administered to determine the prevalence of respiratory symptoms and smoking habits. Using backward regression analysis, cumulative pack-years of cigarette smoking and prevalence of lower respiratory symptoms were statistically significant predictors of a standardized forced expiratory volume at 1 second observed v expected difference; however, TDI exposure, whether classified as current, highest career level, cumulative, or cumulative highest-to-date, was not associated with a decline in forced expiratory volume.

  7. Acute effects of urban ambient air pollution on respiratory symptoms, asthma medication use, and doctor visits for asthma in a cohort of Australian children

    International Nuclear Information System (INIS)

    We enrolled a cohort of primary school children with a history of wheeze (n=148) in an 11-month longitudinal study to examine the relationship between ambient air pollution and respiratory morbidity. We obtained daily air pollution (ozone, particulate matter less than 10 μm, and nitrogen dioxide), meteorological, and pollen data. One hundred twenty-five children remained in the final analysis. We used logistic regression models to determine associations between air pollution and respiratory symptoms, asthma medication use, and doctor visits for asthma. There were no associations between ambient ozone concentrations and respiratory symptoms, asthma medication use, and doctor visits for asthma. There was, however, an association between PM10 concentrations and doctor visits for asthma (RR=1.11, 95% CI=1.04-1.19) and between NO2 concentration and wet cough (RR=1.05, 95% CI=1.003-1.10) in single-pollutant models. The associations remained significant in multipollutant models. There was no consistent evidence that children with wheeze, positive histamine challenge, and doctor diagnosis of asthma reacted differently to air pollution from children with wheeze and doctor diagnosis of asthma and children with wheeze only. There were significant associations between PM10 levels and doctor visits for asthma and an association between NO2 levels and the prevalence of wet cough. We were, however, unable to demonstrate that current levels of ambient air pollution in western Sydney have a coherent range of adverse health effects on children with a history of wheezing

    Full Text Available Abstract Background Guaifenesin is a component of medicines used to improve symptoms associated with upper respiratory tract infections. Patient-reported outcome instruments are valuable for evaluating symptom improvements; however, a validated tool to assess efficacy of mucoactive drugs does not exist. We compared the efficacy of extended-release guaifenesin with placebo for treatment of symptoms of upper respiratory tract infection using subjective efficacy assessments in a pilot study and confirmed precision of assessments in a validation study. Methods The pilot study was a randomized, double-blind study where patients were dosed with either 1200 mg extended-release guaifenesin (n = 188 or placebo (n = 190, every 12 hours for 7 days. Efficacy was assessed using subjective measures including the Daily Cough and Phlegm Diary, the Spontaneous Symptom Severity Assessment and the Wisconsin Upper Respiratory Symptom Survey. End-of-study assessments were completed by patients and investigator. The validation study consisted of two phases. In Phase I, subjects completed interviews to gather evidence to support the content validity of the Daily Cough and Phlegm Diary, the Spontaneous Symptom Severity Assessment and Patient’s End-of-Treatment Assessment. Phase II examined the psychometric properties of assessments evaluated in Phase I of the validation study using data from the pilot study. Results Subjective measures of efficacy at Day 4 showed the most prominent difference between treatment groups, in favor of guaifenesin. The 8-symptom related questions (SUM8 in the Daily Cough and Phlegm Diary, analyzed as a composite score appeared to be the strongest candidate endpoint for further evaluation. Results from the interviews in Phase I supported the content of the assessments which were validated during Phase II. Treatments were well tolerated. Conclusions Results from the clinical pilot and validation studies showed that the SUM8 diary

    2015-01-01

    Physical activity (PA) and exercise are interrelated but separate concepts. PA refers to bodily movement produced by skeletal muscles that results in energy expenditure. Exercise is a subset of PA, in which generally higher levels of muscular activity are performed for a purpose, such as achieving physical fitness or winning a sporting contest. Higher exercise capacity is considered to be permissive of greater PA in the home and community settings. Individuals with chronic obstructive pulmonary disease (COPD) are physically inactive when compared with healthy age-matched control subjects. Furthermore, physical inactivity is independently associated with adverse outcome in patients with COPD, including more rapid disease progression, impaired health status, and increased health care utilization and mortality risk. While there are several methods to objectively measure PA, recent scientific studies have commonly utilized questionnaires and activity monitors. The latter include simple pedometers and complex accelerometers, which can measure and record movement in up to 3 planes. In COPD, multiple patient characteristics and disease severity markers are related to activity level, including pulmonary physiological abnormalities such as airway obstruction and hyperinflation; exercise capacity such as the 6-minute walking distance; exacerbations of respiratory disease; and comorbid conditions. Clinical trials of bronchodilators, supplemental oxygen therapy, exercise training or pulmonary rehabilitation, or PA counseling have provided inconsistent results in demonstrating increased PA from the interaction. This is probably because the phenomenon of physical inactivity is complex, resulting not only from physiological impairments, but symptoms, cultural, motivational, and environmental factors.

  15. Frequency of depression and somatic symptoms in patients on interferon alpha/ribavirin for chronic hepatitis C

    International Nuclear Information System (INIS)

    Large numbers of patients suffering from Chronic Hepatitis C (HCV) are seeking treatment with interferon alpha (IFN) because of significant advances in overall improvement in the course of HCV and its complications. Objectives were to estimate the frequency of depression and somatic symptoms in patients on interferon alpha/ribavirin treatment for chronic hepatitis C. Methods: It was an observational study conducted in the out-patient Department of Gastroenterology Shaikh Zayed Hospital, Lahore during a period of three months, i.e., from September to November 2008. One hundred consecutive patients undergoing interferon alpha/ ribavirin treatment for chronic HCV were included in the study. All patients, irrespective of age, sex or duration of treatment were administered with a check list of common physical complaints and DSM-IV symptoms for Major Depressive Episode. Results: Out of a total of 100 subjects 37 were male and 63 were female. In all, 39 (39%) patients fulfilled the diagnostic criteria of DSM-IV for Major Depressive Episode. Major Depression was more common in female 28 (44.4%) as compared to male 11 (28.7%) patients. Somatic symptoms were common in all the patients but they were reported more frequently by patients with Major Depression compared to those without Major Depression. Myalgias, headache, joint pain, nausea/vomiting, abdominal pain and palpitation were the most common physical symptoms. Conclusion: Major Depression and somatic complaints are a common consequence of interferon alpha/ribavirin treatment for chronic hepatitis C. All patients receiving this treatment should be periodically assessed for the detection of these side effects to promptly address relevant treatment options. (author)

This study aimed to assess the role of disease-specific HRQL for long-term survival in patients of different diagnoses with chronic hypercapnic respiratory failure (CHRF. Methods In a cohort of 231 stable patients (chronic obstructive pulmonary disease (COPD, n = 98; non-COPD (obesity-hypoventilation syndrome, restrictive disorders, neuromuscular disorders, n = 133 with CHRF and current home mechanical ventilation (HMV, HRQL was assessed by the disease-specific Severe Respiratory Insufficiency (SRI questionnaire and its prognostic value was prospectively evaluated during a follow-up of 2–4 years, using univariate and multivariate regression analysis. Results HRQL was more impaired in COPD (mean ± SD SRI-summary score (SRI-SS 52.5 ± 15.6 than non-COPD patients (67.6 ± 16.4; p 1 turned out to be independent predictors (p Conclusion In patients with CHRF and HMV, the disease-specific SRI was an overall predictor of long-term survival in addition to established risk factors. However, the SRI predominantly beared information regarding long-term survival in non-COPD patients, while in COPD patients objective measures of the disease state were superior. This on one hand highlights the significance of HRQL in the long-term course of patients with CHRF, on the other hand it suggests that the predictive value of HRQL depends on the underlying disease.

    Full Text Available Gastroesophageal reflux disease (GERD is defined with clinical symptoms of heart burning and regurgitation. It may be associated with external esophageal symptoms such as chronic cough, asthma, laryngitis, chronic lung disease, sinusitis and pulmonary fibrosis. In the present study, rats with chronic aspiration of gastroduodenal contents were studied for cellular phenotypes and cytokine concentrations in bronchoalveolar lavage and lung tissue. Thirty-six male Albino N-MRI rats were randomly divided into six groups. After anesthesia and tracheal intubation, the animals received either 0.5ml/kg of normal saline (control, gastric juice, pepsin, hydrochloric acid or bile salts by injection into their lungs twice a week for 8 weeks. In sham group nothing was injected. Thereafter, cellular phenotypes and cytokine concentrations of Interleukine (IL-1α, IL-1β, Transforming Growth Factor (TGF-β, Tumor Necrosis Factor (TNF-α, and IL-6 were assessed in bronchoalveolar lavage and lung tissue homogenates. The numbers of epithelial cells, macrophages, neutrophils and lymphocytes in BAL and levels of cytokines IL-1α, IL-6, TNF-α and TGF-β in BAL and lung tissue of test groups were significantly higher than the control group. Aspiration of bile salts caused more cytokine levels and inflammatory cells compared to other reflux components. It can be concluded that GERD with increased cytokines and inflammatory cells in lung could cause or exacerbate asthma and pulmonary fibrosis.

    This research aims to investigate the rate and nature of anxiety symptoms in a group of children and adolescents living with chronic illnesses in Jordan, and their relation to social desirability in a cultural sample not previously researched. Using the Revised Children's Manifest Anxiety Scale (R-CMAS), anxiety and social desirability data were obtained from 114 children diagnosed with chronic illnesses and 162 healthy control participants. Based on children's self-report, participants were categorized according to their adaptive style paradigm as either high anxious, low anxious, or repressor. It was proposed that children who score high on social desirability and low on anxiety are repressors. The prevalence of these categories was compared across the two groups. Anxiety was reported in 9.64 percent of the chronic illnesses and 12.34 percent of the healthy peers. Using the data obtained in the present study, the rate and nature of anxiety in children with chronic illnesses were lower for children in Jordan when compared to previous studies. However, social desirability values were similar to those established in Western societies suggesting a significantly higher percentage of children identified as repressors in children with long-term illnesses. These results supported the hypothesis regarding the relationship between social desirability and expressed anxiety symptoms. PMID:23242812

    Using the US EPA 100 office-building BASE Study dataset, they conducted multivariate logistic regression analyses to quantify the relationship between indoor CO{sub 2} concentrations (dCO{sub 2}) and mucous membrane (MM) and lower respiratory system (LResp) building related symptoms, adjusting for age, sex, smoking status, presence of carpet in workspace, thermal exposure, relative humidity, and a marker for entrained automobile exhaust. In addition, they tested the hypothesis that certain environmentally-mediated health conditions (e.g., allergies and asthma) confer increased susceptibility to building related symptoms within office buildings. Adjusted odds ratios (ORs) for statistically significant, dose-dependent associations (p < 0.05) for dry eyes, sore throat, nose/sinus congestion, and wheeze symptoms with 100 ppm increases in dCO{sub 2} ranged from 1.1 to 1.2. These results suggest that increases in the ventilation rates per person among typical office buildings will, on average, reduce the prevalence of several building related symptoms by up to 70%, even when these buildings meet the existing ASHRAE ventilation standards for office buildings. Building occupants with certain environmentally-mediated health conditions are more likely to experience building related symptoms than those without these conditions (statistically significant ORs ranged from 2 to 11).

    Action Plan B3 of the European Innovation Partnership on Active and Healthy Ageing (EIP on AHA) focuses on the integrated care of chronic diseases. Area 5 (Care Pathways) was initiated using chronic respiratory diseases as a model. The chronic respiratory disease action plan includes (1) AIRWAYS integrated care pathways (ICPs), (2) the joint initiative between the Reference site MACVIA-LR (Contre les MAladies Chroniques pour un VIeillissement Actif) and ARIA (Allergic Rhinitis and its Impact on Asthma), (3) Commitments for Action to the European Innovation Partnership on Active and Healthy Ageing and the AIRWAYS ICPs network. It is deployed in collaboration with the World Health Organization Global Alliance against Chronic Respiratory Diseases (GARD). The European Innovation Partnership on Active and Healthy Ageing has proposed a 5-step framework for developing an individual scaling up strategy: (1) what to scale up: (1-a) databases of good practices, (1-b) assessment of viability of the scaling up of good practices, (1-c) classification of good practices for local replication and (2) how to scale up: (2-a) facilitating partnerships for scaling up, (2-b) implementation of key success factors and lessons learnt, including emerging technologies for individualised and predictive medicine. This strategy has already been applied to the chronic respiratory disease action plan of the European Innovation Partnership on Active and Healthy Ageing. PMID:27478588

    Asthma and chronic obstructive pulmonary disease (COPD) are highly prevalent chronic diseases in the general population. Both are characterized by similar mechanisms: airway inflammation, airway obstruction, and airway hyperresponsiveness. However, the distinction between the two obstructive diseases is not always clear.

    The aim of the present study was to assess the relationship between illness-related characteristics, such as symptom severity and psychosocial functioning, and specific aspects of family functioning both in patients experiencing their first episode of psychosis (FEP) and chronically ill patients. A total of 50 FEP and 50 chronic patients diagnosed with schizophrenia or bipolar disorder (most recent episode manic severe with psychotic features) and their family caregivers participated in the study. Family functioning was evaluated in terms of cohesion and flexibility (FACES IV Package), expressed emotion (FQ), family burden (FBS) and caregivers' psychological distress (GHQ-28). Patients' symptom severity (BPRS) and psychosocial functioning (GAS) were assessed by their treating psychiatrist within 2 weeks from the caregivers' assessment. Increased symptom severity was associated with greater dysfunction in terms of family cohesion and flexibility (β coefficient -0.13; 95 % CI -0.23, -0.03), increased caregivers' EE levels on the form of emotional overinvolvement (β coefficient 1.03; 95 % CI 0.02, 2.03), and psychological distress (β coefficient 3.37; 95 % CI 1.29, 5.45). Family burden was found to be significantly related to both symptom severity (β coefficient 3.01; 95 % CI 1.50, 4.51) and patient's functioning (β coefficient -2.04; 95 % CI -3.55, -0.53). No significant interaction effect of chronicity was observed in the afore-mentioned associations. These findings indicate that severe psychopathology and patient's low psychosocial functioning are associated with poor family functioning. It appears that the effect for family function is significant from the early stages of the illness. Thus, early psychoeducational interventions should focus on patients with severe symptomatology and impaired functioning and their families. PMID:26286079

    The main goal of the current study was to investigate sex differences in the relationship between the level of trauma symptoms appearing in posttraumatic stress disorder (PTSD) and intensity of pain in a sample of 300 Polish patients suffering from chronic pain, specifically rheumatoid arthritis and lower back pain. We also focused on participants' body image with body esteem as a mediator. To assess the intensity of pain among participants, we used the Numerical Rating Scale. The level of trauma symptoms was assessed with the PTSD Factorial Version Inventory. To measure body image among participants, we used the Body Esteem Scale. The results of our study suggest that trauma symptoms and body image dimensions were significant predictors of pain intensity among men suffering from chronic pain. Moreover, trauma symptoms and age were significant predictors of pain intensity among women suffering from chronic pain. Finally, we demonstrated that sex differentiates the reaction to chronic pain.

    The incidence of lower urinary tract symptoms, including overactive bladder (OAB), is continuing to rise, and is associated with a negative impact on quality of life and a heavy economic burden. A major risk factor for OAB is advancing age. The etiology of OAB is multifactorial and appears to involve myogenic, neurogenic, and urotheliogenic factors. In this article, we review the strengthening preclinical evidence supporting the contribution of chronic pelvic ischemia to the pathogenesis of OAB. In animal models, chronic ischemia induced by arterial injury and a high-fat diet upregulates markers of oxidative stress and proinflammatory cytokines in the urothelium and lamina propria, and leads to increased expression of nerve growth factor. These processes result in increased afferent activity and an increased frequency of micturition, reflecting a state of bladder hyperactivity. In severe, prolonged cases, bladder overactivity may develop into underactivity. Antimuscarinic therapies are the mainstay of OAB treatment, but their usefulness is limited by modest efficacy and troublesome side-effects. Our increasing understanding of the contribution of chronic ischemia to OAB is leading toward novel therapeutic options targeting chronic pelvic ischemia and its morphological, functional, and oxidative consequences. Preclinical trials have demonstrated encouraging results with α1 -adrenoreceptor blockade, phosphodiesterase type 5 inhibition, β3 -adrenoreceptor agonism, free radical scavenging, and stem cell therapy, in preventing morphological, biochemical and functional changes induced by chronic bladder ischemia.

    A 6-month-old Holstein heifer that was nonresponsive to medical treatment was evaluated for chronic respiratory disease. Complete blood count and serum chemistry revealed neutrophilic leukocytosis and low globulin levels. Assays for bovine leukemia virus, bovine virus diarrhea, and bovine leukocyte adhesion deficiency were negative. Serum globulin subclass assays revealed transient low concentrations of immunoglobulin (Ig) G1 and IgA, persistent low IgG2, and subnormal IgM. Vaccination with 2 doses of multiple, inactived viruses induced seroconversion for most viruses. Flow cytometric analysis of blood lymphocyte subpopulation demonstrated an increase in CD5+ B-cells. Blood lymphocyte proliferation and neutrophil function tests were normal. Results of immunologic assays indicated IgG2 deficiency with transient hypogammaglobulinemia. PMID:15460327

    Full Text Available Abstract Background In a study by Wagner et al., the CDC Symptom Inventory was validated in a population selected from the inhabitants of a city in the USA, and proofed reliable for the assessment of the accompanying symptoms of CFS. The Dutch translation of the CDC Symptom Inventory is compared to the original and the psychometric properties are presented for patients in a tertiary care setting. Methods One hundred thirty-nine consecutive patients who visited the CFS Center Amsterdam for the first time were asked to complete the CDC Symptom Inventory in the Dutch Language Version (DLV together with the usual set of questionnaires. Sixty-one patients had Chronic Fatigue (CF and 78 patients fulfilled the criteria for CFS. Forty-three healthy accompanying persons completed the CDC Symptom Inventory DLV, the Physical Functioning scale of the Medical Outcome Survey Short Form-36 DLV, and the Fatigue and Concentration scales of the Checklist Individual Strength (CIS-20. Results The healthy controls group contained fewer women and was overall older than the patient groups. The influence of gender on the CDC Symptom Inventory DLV was significant but the effect of age was not. The Dutch version had a good internal consistency and convergent validity. The results were comparable to the original English version, but the sex-related difference needs further study. Conclusion The Dutch version of the CDC Symptom Inventory is a reliable tool for the assessment of the secondary criteria for CFS. The results show that it is comparable to the outcome of studies in English speaking countries.

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

    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.

  12. Chronic air-flow limitation does not increase respiratory epithelial permeability assessed by aerosolized solute, but smoking does

    International Nuclear Information System (INIS)

    To determine the separate influences of smoking and severe air-flow limitation on aerosol deposition and respiratory epithelial permeability, we studied 26 normal nonsmokers, 12 smokers without airway obstruction, 12 nonsmokers with chronic obstructive pulmonary disease (COPD), and 11 smokers with COPD. We aerosolized 99mTc-labeled diethylene triamine pentaacetic acid to particles approximately 1 micron activity median aerodynamic diameter. Levels of radioactivity were plotted semilogarithmically against time to calculate clearance as percent per minute. The distribution of radioactivity was homogeneous in control subjects and in smokers, but patchy in both groups with COPD. No difference was found between clearances of the control group (1.18 +/- 0.31% min-1), and nonsmoker COPD group (1.37 +/- 0.82% min-1), whereas values in smokers without COPD (4.00 +/- 1.70% min-1) and smokers with COPD (3.62 +/- 2.88% min-1) were significantly greater than in both nonsmoking groups. We conclude that (1) small particles appear to deposit peripherally, even with severe COPD; (2) respiratory epithelial permeability is normal in nonsmokers with COPD; (3) smoking increases permeability by a mechanism unrelated to air-flow limitation

Methods: Included were 92 employees with chronic musculoskeletal disorders who had participated in a 57-week multidisciplinary rehabilitation program. Their ages ranged from 25–59 years. The Hospital Anxiety and Depression Scale was used to assess depressive symptoms. Different aspects of physical functioning (muscle strength, mobility, endurance capacity, and balance were measured with single-item visual analog scales, and physical fitness was measured with the validated COOP/WONCA charts. Being on "active work strategies," such as receiving rehabilitation benefit/vocational rehabilitation or being reported partly or completely fit, was defined as "on their way into/in work". Cross-sectional associations were measured using logistic regression models, estimating odds ratio with 95% confidence intervals. Results: There were no differences between the "on their way into/in work" group (n=70 and the "on their way out/out of work" group (n=22 regarding age, sex, or levels of anxiety or pain. Surprisingly, regression analyses showed that those with higher levels of physical functioning had significantly lower odds of returning to work. Conclusion: The findings of an inverse relationship between self-reported physical function and returning to work in this sample illustrate that the return-to-work process among employees with chronic musculoskeletal pain and comorbid depressive symptoms is multifactorial and influenced by factors other than

    We investigated in anesthetized guinea pigs the involvement of tachykinins in respiratory alterations after an airway intoxication by sulfur mustard (SM). Early lesions were evaluated after 5h. Respiratory system resistance (R) and compliance were measured by the occlusion method and airway microvascular permeability by measuring the Evans Blue dye concentration in the trachea and main bronchi. Two groups of animals were studied treated with capsaicin (which induces a tachykinin depletion) or by its vehicle. Capsaicin pretreatment had no effect on the measured parameters. We also measured 14 J after the intoxication tracheal epithelium neutral endopeptidase (NEP) (the main enzyme which degrades tachykinins). In addition bronchial responsiveness to exogenous substance P was studied in two groups of animals intoxicated with SM or not. Tracheal epithelium NEP activity was decreased from 0.448 + or 0.027 nmol.min- 1.mg protein- 1 in controls to 0. 182 + or 0.038 in intoxicated animals. Response to substance P was greater in intoxicated animals with R=2.98 + or - 1.57 cmH20.MI-1.s versus 0.35 + or 0.02 in controls, after 5.10-5 M aerosolized substance P These results suggest tachykinins are not preponderant in the early stage lesions but that bronchial hyperactivity is present at recovery, related to epithelium NEP depletion.

    To evaluate the effects of the intelligent-turtle massage on the physical symptoms and immune functions in patients with chronic fatigue syndrome (CFS). Methods: 182 cases of CFS were randomly divided into an experimental group of 91 cases treated by the intelligent-turtle massage,and a control group of 91 cases treated with the conventional massage method. After 2 courses of treatment,the therapeutic effects were statistically analyzed with the accumulated score for the improved clinical symptoms; and the changes of IgA,IgM and IgG were compared in 96 cases. Results: There was a significant difference between the two groups in the accumulated scores for improvement of the symptoms (P<0.05). A remarkable difference was found in the therapeutic effect. And there was a significant difference in the IgA,IgM and IgG levels between the two groups (P<0.05). Conclusion: The intelligent-turtle massage is an effective therapy for relieving the physical symptoms of CFS,and it may show certain effects on the immune functions.

Objectives Evaluate gender differences in respiratory factors associated with dyspnea in COPD patients. Methods In a FEV1 % matched population of 100 men and women with COPD we measured: age, MMRC, FEV1, FVC, TLC, IC/TLC, PaO2, PaCO2, DLCO, Pimax, P0.1, Ti/Ttot, BMI, ffmi, 6MWD and VAS scale before and after the test, the Charlson score and the SGRQ. We estimated the association between these parameters and MMRC scores. Multivariate analysis determined the independent strength of those associations. Results MMRC correlated with: BMI (men:-0.29, p = 0.04; women:-0.28, p = 0.05, ffmi (men:-0.39, p = 0.01, FEV1 % (men:-0.64, p 2 (men:-0.59, p 2 (men:0.27, p = 0.05, DLCO (men:-0.54, p 0.1/Pimax (men:0.46, p = 0.002; women:0.47, p = 0.005, dyspnea measured with the Visual Analog Scale before (men:0.37, p = 0.04; women:0.52, p = 0.004 and after 6MWD (men:0.52, p = 0.002; women:0.48, p = 0.004 and SGRQ total (men:0.50, p 0.1/Pimax in women (r2 = 0.30 and BMI, DLCO, PaO2 and P0.1/Pimax in men (r2 = 0.81 were the strongest predictors of MMRC scores. Conclusion In mild to severe COPD patients attending a pulmonary clinic, P0.1/Pimax was the unique predictor of MMRC scores only in women. Respiratory factors explain most of the variations of MMRC scores in men but not in women. Factors other than the respiratory ones should be included in the evaluation of dyspnea in women with COPD.

    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:Oxygen inhalation therapy is essential for the treatment of patients with chronic mountain sickness (CMS),but the efficacy of oxygen inhalation for populations at high risk of CMS remains unknown.This research investigated whether oxygen inhalation therapy benefits populations at high risk of CMS.Methods:A total of 296 local residents living at an altitude of 3658 m were included;of which these were 25 diagnosed cases of CMS,8 cases dropped out of the study,and 263 cases were included in the analysis.The subjects were divided into high-risk (180 ≤ hemoglobin (Hb) <210 g/L,n =161) and low-risk (Hb <180 g/L,n =102) groups,and the cases in each group were divided into severe symptom (CMS score ≥6) and mild symptom (CMS score 0-5) subgroups.Severe symptomatic population of either high-or low-risk CMS was randomly assigned to no oxygen intake group (A group) or oxygen intake 7 times/week group (D group);mild symptomatic population of either high-or low-risk CMS was randomly assigned to no oxygen intake group (A group),oxygen intake 2 times/week group (B group),and 4 times/week group (C group).The courses for oxygen intake were all 30 days.The CMS symptoms,sleep quality,physiological biomarkers,biochemical markers,etc.,were recorded on the day before oxygen intake,on the 15th and 30th days of oxygen intake,and on the 15th day after terminating oxygen intake therapy.Results:A total of 263 residents were finally included in the analysis.Among these high-altitude residents,CMS symptom scores decreased for oxygen inhalation methods B,C,and D at 15 and 30 days after oxygen intake and 15 days after termination,including dyspnea,palpitation,and headache index,compared to those before oxygen intake (B group:Z =5.604,5.092,5.741;C group:Z =4.155,4.068,4.809;D group:Z =6.021,6.196,5.331,at the 3 time points respectively;all P < 0.05/3 vs.before intake).However,dyspnea/palpitation (A group:Z =5.003,5.428,5.493,both P < 0.05/3 vs.before intake) and headache (A

    Sports training and competition are significant sources of stress, especially for young athletes. It is well known that physiological and psychological stressors induce neuroendocrine responses that could modulate immune system function. However, to date, little is known about the immune responses of young soccer players during a competitive season. Therefore, this study examined the effects of a 21-week competitive season divided into preseason, competitive season, and detraining on salivary immunoglobulin A (SIgA), upper respiratory tract infection (URTI) symptoms, and salivary cortisol in preadolescent male soccer players. Thirty-four young soccer players agreed to participate, and 26 (12.9 ± 0.2 years) completed the entire study. The investigation period was structured as follows: a 12-week preparatory training phase (preseason training), a 7-week competitive and a 2-week detraining phase. Resting saliva samples were taken to determine cortisol and SIgA responses. The players were required to complete a weekly log during the entire investigation reporting every sign or symptoms consistent with URTI. A significant increase in SIgA secretion rate and a decrease in URTI symptoms were observed after the 2-week detraining period (p Sport coaches should monitor markers of mucosal immune function to minimize illness that ultimately might lead to a decrease in performance.

Beyond pharmacological treatment, supplemental oxygen and mechanical ventilation are major treatment options. This review describes the physiological concepts underlying respiratory failure and its therapy, as well as important treatment outcomes. The rationale for the controlled supply of oxygen in acute hypoxic respiratory failure is undisputed. There is also a clear survival benefit from long-term oxygen therapy in patients with chronic hypoxia, while in mild, nocturnal, or exercise-induced hypoxemia such long-term benefits appear questionable. Furthermore, much evidence supports the use of non-invasive positive pressure ventilation in acute hypercapnic respiratory failure. It application reduces intubation and mortality rates, and the duration of intensive care unit or hospital stays, particularly in the presence of mild to moderate respiratory acidosis. COPD with chronic hypercapnic respiratory failure became a major indication for domiciliary mechanical ventilation, based on pathophysiological reasoning and on data regarding symptoms and quality of life. Still, however, its relevance for long-term survival has to be substantiated in prospective controlled studies. Such studies might preferentially recruit patients with repeated hypercapnic decompensation or a high risk for death, while ensuring effective ventilation and the patients’ adherence to therapy.Keywords: respiratory failure, COPD, mechanical ventilation, non-invasive ventilation long-term oxygen therapy, chronic

    Although an association between both sleep duration and disturbance with salivary cortisol has been suggested, little is known about the long term effects of poor quality sleep on diurnal cortisol rhythm. The aim of this study was to examine the association of poor quality sleep, categorised as recurrent short sleep duration and chronic insomnia symptoms, with the diurnal release of cortisol. We examined this in 3314 participants from an occupational cohort, originally recruited in 1985-1989. Salivary cortisol was measured in 2007-2009 and six saliva samples were collected: (1) waking, (2) waking+0.5h, (3) +2.5h, (4) +8h, (5) +12h and (6) bedtime, for assessment of the cortisol awakening response and the diurnal slope in cortisol secretion. Participants with the first saliva sample collected within 15min of waking and not on steroid medication were examined. Short sleep duration (≤5h) and insomnia symptoms (Jenkins scale, highest quartile) were measured in 1997-1999, 2003-2004 and 2007-2009. Recurrent short sleep was associated with a flatter diurnal cortisol pattern. A steeper morning rise in cortisol was observed among those reporting chronic insomnia symptoms at three time points and among those reporting short sleep twice, compared to those who never reported sleep problems. Participants reporting short sleep on three occasions had higher levels of cortisol later in the day, compared to those never reporting short sleep, indicated by a positive interaction with hours since waking (β=0.02 (95% CI: 0.01, 0.03)). We conclude that recurrent sleep problems are associated with adverse salivary cortisol patterns throughout the day. PMID:26963375

    Objective: Poor treatment adherence is a major problem among individuals with chronic illness. Research indicates that adherence is worsened when accompanied by depressive symptoms. In this preliminary study, we aimed to describe how a patient-centered approach could be employed to aid patients with depressive symptoms in following their treatment regimens. Methods: The sample consisted of 14 patients undergoing antiretroviral therapy (ART) for HIV who reported clinically-significant depressive symptoms. Participant ratings of 23 treatment-related statements were examined using two assessment and analytic techniques. Interviews were conducted with participants to determine their views of information based on the technique. Results: Results indicate that while participants with optimal adherence focused on views of treatment associated with side effects to a greater extent than participants with poor adherence, they tended to relate these side effects to sources of intrinsic motivation. Conclusion: The study provides examples of how practitioners could employ the assessment techniques outlined to better understand how patients think about treatment and aid them in effectively framing their health-related goals.

    Full Text Available Abstract Chronic fatigue syndrome (CFS is complex illness of unknown etiology. Among the broad range of symptoms, many patients report disturbances in the emotional realm, the most frequent of which is anxiety. Research shows that patients with CFS and other so-called functional somatic disorders have alterations in the intestinal microbial flora. Emerging studies have suggested that pathogenic and non-pathogenic gut bacteria might influence mood-related symptoms and even behavior in animals and humans. In this pilot study, 39 CFS patients were randomized to receive either 24 billion colony forming units of Lactobacillus casei strain Shirota (LcS or a placebo daily for two months. Patients provided stool samples and completed the Beck Depression and Beck Anxiety Inventories before and after the intervention. We found a significant rise in both Lactobacillus and Bifidobacteria in those taking the LcS, and there was also a significant decrease in anxiety symptoms among those taking the probiotic vs controls (p = 0.01. These results lend further support to the presence of a gut-brain interface, one that may be mediated by microbes that reside or pass through the intestinal tract.

    Full Text Available OBJECTIVE: To evaluate the impact of asthma, by gender, in a population sample of asthma patients in Brazil. METHODS: We conducted face-to-face interviews with 400 subjects (> 12 years of age included in a national probability telephone sample of asthma patients in the Brazilian state capitals of São Paulo, Rio de Janeiro, Curitiba, and Salvador. Each of those 400 subjects completed a 53-item questionnaire that addressed five asthma domains: symptoms; impact of asthma on quality of life; perception of asthma control; exacerbations; and treatment/medication. RESULTS: Of the 400 patients interviewed, 272 (68% were female. In relation to respiratory symptoms, the proportion of women reporting extremely bothersome symptoms (cough with sputum, tightness in the chest, cough/shortness of breath/tightness in the chest during exercise, nocturnal shortness of breath, and nocturnal cough was greater than was that of men. Daytime symptoms, such as cough, shortness of breath, wheezing, and tightness in the chest, were more common among women than among men. Women also more often reported that their asthma interfered with normal physical exertion, social activities, sleep, and life in general. Regarding the impact of asthma on quality of life, the proportion of subjects who reported that asthma caused them to feel that they had no control over their lives and affected the way that they felt about themselves was also greater among women than among men. CONCLUSIONS: Among women, asthma tends to be more symptomatic, as well as having a more pronounced effect on activities of daily living and on quality of life.

The present study investigated which IOS measurement is correlated with airflow obstruction, airway conductance and lung volume in chronic obstructive pulmonary disease (COPD). A total of 180 patients with COPD were selected and 95 agreed to follow‑up 1 year after the initial tests. IOS measurements [R5, R20, X5 and resonant frequency (Fres)], body plethysmography [forced end‑expiratory flow (FEF)75, total lung capacity, residual volume (RV) and total inspiratory resistance (Rtot)] and spirometry [forced expiratory volume in 1 sec (FEV1)] were performed. Pearson's or Spearman's correlation tests were used to determine the correlation between the IOS and other measurements. R5, X5 and Fres were all significantly associated (Pcompliance caused by airflow obstruction. PMID:25189185

    Individuals with chronic fatigue syndrome (CFS) have heightened sensitivity and increased symptoms following various physiologic challenges, such as orthostatic stress, physical exercise, and cognitive challenges. Similar heightened sensitivity to the same stressors in fibromyalgia (FM) has led investigators to propose that these findings reflect a state of central sensitivity. A large body of evidence supports the concept of central sensitivity in FM. A more modest literature provides partial support for this model in CFS, particularly with regard to pain. Nonetheless, fatigue and cognitive dysfunction have not been explained by the central sensitivity data thus far. Peripheral factors have attracted attention recently as contributors to central sensitivity. Work by Brieg, Sunderland, and others has emphasized the ability of the nervous system to undergo accommodative changes in length in response to the range of limb and trunk movements carried out during daily activity. If that ability to elongate is impaired-due to movement restrictions in tissues adjacent to nerves, or due to swelling or adhesions within the nerve itself-the result is an increase in mechanical tension within the nerve. This adverse neural tension, also termed neurodynamic dysfunction, is thought to contribute to pain and other symptoms through a variety of mechanisms. These include mechanical sensitization and altered nociceptive signaling, altered proprioception, adverse patterns of muscle recruitment and force of muscle contraction, reduced intra-neural blood flow, and release of inflammatory neuropeptides. Because it is not possible to differentiate completely between adverse neural tension and strain in muscles, fascia, and other soft tissues, we use the more general term "neuromuscular strain." In our clinical work, we have found that neuromuscular restrictions are common in CFS, and that many symptoms of CFS can be reproduced by selectively adding neuromuscular strain during the

  6. Effects of Air Pollution and the Introduction of the London Low Emission Zone on the Prevalence of Respiratory and Allergic Symptoms in Schoolchildren in East London: A Sequential Cross-Sectional Study.

    Full Text Available The adverse effects of traffic-related air pollution on children's respiratory health have been widely reported, but few studies have evaluated the impact of traffic-control policies designed to reduce urban air pollution. We assessed associations between traffic-related air pollutants and respiratory/allergic symptoms amongst 8-9 year-old schoolchildren living within the London Low Emission Zone (LEZ. Information on respiratory/allergic symptoms was obtained using a parent-completed questionnaire and linked to modelled annual air pollutant concentrations based on the residential address of each child, using a multivariable mixed effects logistic regression analysis. Exposure to traffic-related air pollutants was associated with current rhinitis: NOx (OR 1.01, 95% CI 1.00-1.02, NO2 (1.03, 1.00-1.06, PM10 (1.16, 1.04-1.28 and PM2.5 (1.38, 1.08-1.78, all per μg/m3 of pollutant, but not with other respiratory/allergic symptoms. The LEZ did not reduce ambient air pollution levels, or affect the prevalence of respiratory/allergic symptoms over the period studied. These data confirm the previous association between traffic-related air pollutant exposures and symptoms of current rhinitis. Importantly, the London LEZ has not significantly improved air quality within the city, or the respiratory health of the resident population in its first three years of operation. This highlights the need for more robust measures to reduce traffic emissions.

    Long-term oxygen therapy improves the life expectancy of hypoxaemic patients with chronic obstructive pulmonary disease (COPD), provided the hypoxaemia is sufficiently pronounced under stable conditions (PaO2 less than 55 mmHg) and oxygen is given for more than 16 out of 24 hours. By extension, the same indications are applicable to hypoxaemia due to other causes (diffuse fibrosis, pneumoconiosis, cystic fibrosis, etc.). Long-term oxygen therapy improves the patients' quality of life and also has favourable effects on oxygen transport, neuropsychological status, polycythaemia and pulmonary hypertension. It is usually delivered by means of O2 extractors, to which may be added small flasks of O2 gas for walking and moving about. Liquid O2 is a good solution for subjects who are motivated and are obliged to do a great deal of walking. The O2 flow rate administered must be such that it rises the PaO2 level above 60 mmHg. Oxygen therapy is only a symptomatic treatment and cannot replace other types of therapy, such as bronchodilators, physiotherapy, etc. It gives satisfactory results but it has not transformed the prognosis of severe hypoxaemic COPD.

    Full Text Available Abstract Background The economical impact of absenteeism and reduced productivity due to acute infectious respiratory and gastrointestinal disease is normally not in the focus of surveillance systems and may therefore be underestimated. However, large community studies in Europe and USA have shown that communicable diseases have a great impact on morbidity and lead to millions of lost days at work, school and university each year. Hand disinfection is acknowledged as key element for infection control, but its effect in open, work place settings is unclear. Methods Our study involved a prospective, controlled, intervention-control group design to assess the epidemiological and economical impact of alcohol-based hand disinfectants use at work place. Volunteers in public administrations in the municipality of the city of Greifswald were randomized in two groups. Participants in the intervention group were provided with alcoholic hand disinfection, the control group was unchanged. Respiratory and gastrointestinal symptoms and days of work were recorded based on a monthly questionnaire over one year. On the whole, 1230 person months were evaluated. Results Hand disinfection reduced the number of episodes of illness for the majority of the registered symptoms. This effect became statistically significant for common cold (OR = 0.35 [0.17 - 0.71], p = 0.003, fever (OR = 0.38 [0.14-0.99], p = 0.035 and coughing (OR = 0.45 [0.22 - 0.91], p = 0.02. Participants in the intervention group reported less days ill for most symptoms assessed, e.g. colds (2.07 vs. 2.78%, p = 0.008, fever (0.25 vs. 0.31%, p = 0.037 and cough (1.85 vs. 2.00%, p = 0.024. For diarrhoea, the odds ratio for being absent became statistically significant too (0.11 (CI 0.01 - 0.93. Conclusion Hand disinfection can easily be introduced and maintained outside clinical settings as part of the daily hand hygiene. Therefore it appears as an interesting, cost-efficient method within the scope

  14. Adhesive capsulitis: An age related symptom of metabolic syndrome and chronic low-grade inflammation?

    Science.gov (United States)

    Pietrzak, Max

    2016-03-01

    Adhesive capsulitis (AC) is very poorly understood, particularly it's underlying etiology. Obesity and metabolic syndrome, which are strongly associated with chronic low grade inflammation, are becoming increasingly understood to underlie a raft of morbid states including upper limb pain syndromes, diabetes (DM), cardiovascular disease (CVD), cancer and central nervous system dysfunction and degeneration. Notwithstanding age, two of the strongest established risk factors for AC are DM and CVD. The hypothesis argues that similar to DM and CVD, the inflammation and capsular fibrosis seen in AC is precipitated by metabolic syndrome and chronic low grade inflammation. These pathophysiological mechanisms are highly likely to be perpetuated by upregulation of pro-inflammatory cytokine production, sympathetic dominance of autonomic balance, and neuro-immune activation. The hypothesis predicts and describes how these processes may etiologically underpin and induce each sub-classification of AC. An improved understanding of the etiology of AC may lead to more accurate diagnosis, improved management, treatment outcomes, and reduce or prevent pain, disability and suffering associated with the disease. The paper follows on with a discussion of similarities between the pathophysiology of AC to general systemic inflammatory control mechanisms whereby connective tissue (CT) fibrosis is induced as a storage depot for leukocytes and chronic inflammatory cells. The potential role of hyaluronic acid (HA), the primary component of the extracellular matrix (ECM) and CT, in the pathophysiology of AC is also discussed with potential treatment implications. Lastly, a biochemical link between physical and mental health through the ECM is described and the concept of a periventricular-limbic central driver of CT dysfunction is introduced. PMID:26880627

N-acetylcysteine (NAC is commonly prescribed for such patients but with uncertain clinical benefits. We postulated that oral NAC, at much larger doses than those ordinarily prescribed, would improve clinical outcomes in a subset of patients with COPD and chronic bronchitis. Objective: The aim of this study was to determine whether very high-dose NAC would improve respiratory health status in patients with COPD and chronic bronchitis. Methods: Patients with COPD and chronic bronchitis were enrolled in a randomized, controlled, double-blinded trial. Patients received oral NAC (1,800 mg or matching placebo twice daily for 8 weeks in addition to their usual respiratory medications. The primary outcome, respiratory health status, was assessed by changes in the St George’s Respiratory Questionnaire. The effects of NAC on lung function and circulating markers of oxidative stress and inflammation were also evaluated. Results: We terminated the study prematurely because new external information suggested the possibility of a safety issue. Of the planned 130 patients, 51 were randomized and 45 (22 in the placebo arm and 23 in the NAC arm completed the study. There was no statistically significant difference between

    Full Text Available Abstract Background To produce a conceptually equivalent Arabic version to the original Self-Administered Chronic Respiratory Disease Questionnaire with standardized dyspnea domain (CRQ-SAS and to assess its reliability. Methods The study was carried out in two stages: stage I which was the translation of the CRQ-SAS questionnaire from the English to the Arabic language, and stage II which represented the test-retest reliability for patients receiving usual care for COPD who were not yet admitted to the pulmonary rehabilitation program. Results Forty five patients with stable COPD were enrolled in this study. Strong test-retest reliability was found for the four domains of the CRQ-SAS, with the intra-class correlation coefficient of 0.97 for each of the domains. The association between most parameters and the four domains of CRQ-SAS were not found to be statistically significant, as measured by Pearson correlation. The number of exacerbations was negatively correlated with the dyspnea domain (correlation = -0.36, p-value = 0.02. The disease duration was negatively correlated with the domain fatigue (correlation = -0.35, p-value = 0.02. The correlation between FEV1/FVC ratio and emotion domain was -0.30 (p-value = 0.05. The mastery domain was negatively correlated with FEV1/FVC ratio with a correlation of -0.27 with borderline statistical significance (p-value = 0.07. Conclusion The Arabic translation of the CRQ-SAS was found to be reliable to assess the quality of life among patients with COPD.

    Identification of bacteria causing lower-airway infections is important to determine appropriate antimicrobial therapy. Flexible bronchoscopy with bronchoalveolar lavage (BAL) is used to obtain lower-airway specimens in young children. The first lavage (lavage-1) is typically used for bacterial culture. However, no studies in children have compared the detection of cultivable bacteria from sequential lavages of the same lobe. BAL fluid was collected from two sequential lavages of the same lobe in 79 children enrolled in our prospective studies of chronic cough. The respiratory bacteria Streptococcus pneumoniae, Haemophilus influenzae, Moraxella catarrhalis, Staphylococcus aureus and Haemophilus parainfluenzae were isolated and identified using standard published methods. H. influenzae was differentiated from Haemophilus haemolyticus using PCR assays. Lower-airway infection was defined as ≥ 104 c.f.u. ml- 1 BAL fluid. We compared cultivable bacteria from lavage-1 with those from the second lavage (lavage-2) using the κ statistic. Lower-airway infections by any pathogen were detected in 46% of first lavages and 39% of second lavages. Detection was similar in both lavages for all pathogens; the κ statistic was 0.7-0.8 for all bacteria except H. parainfluenzae. Of all infections detected in either lavage, 90% were detected in lavage-1 and 78  in lavage-2. However, culture of lavage-2 identified infections that would have been missed in 8% of children, including infections by additional Streptococcus pneumoniae serotypes. Our findings support the continued use of lavage-1 for bacterial culture; however, culture of lavage-2 may yield additional identifications of bacterial pathogens in lower-airway infections.

    Patient: Male, 25 Final Diagnosis: Ulcerative colitis and chronic fatigue syndrome Symptoms: Colitis • profound fatigue • multi-joint pain • cognitive impairment • corneal keratitis Medication: — Clinical Procedure: VIP replacement therapy Specialty: Family Medicine Objective: Unusual clinical course Background: Patients with multisymptom chronic conditions, such as refractory ulcerative colitis (RUC) and chronic fatigue syndrome (CFS), present diagnostic and management challenges for clinicians, as well as the opportunity to recognize and treat emerging disease entities. In the current case we report reversal of co-existing RUC and CFS symptoms arising from biotoxin exposures in a genetically susceptible individual. Case Report: A 25-year-old previously healthy male with new-onset refractory ulcerative colitis (RUC) and chronic fatigue syndrome (CFS) tested negative for autoimmune disease biomarkers. However, urine mycotoxin panel testing was positive for trichothecene group and air filter testing from the patient’s water-damaged rental house identified the toxic mold Stachybotrys chartarum. HLA-DR/DQ testing revealed a multisusceptible haplotype for development of chronic inflammation, and serum chronic inflammatory response syndrome (CIRS) biomarker testing was positive for highly elevated TGF-beta and a clinically undetectable level of vasoactive intestinal peptide (VIP). Following elimination of biotoxin exposures, VIP replacement therapy, dental extractions, and implementation of a mind body intervention-relaxation response (MBI-RR) program, the patient’s symptoms resolved. He is off medications, back to work, and resuming normal exercise. Conclusions: This constellation of RUC and CFS symptoms in an HLA-DR/DQ genetically susceptible individual with biotoxin exposures is consistent with the recently described CIRS disease pathophysiology. Chronic immune disturbance (turbatio immuno) can be identified with clinically available CIRS biomarkers and

    Full Text Available Abstract Background The association between chronic respiratory diseases and work disability has been demonstrated a number of times over the past 20 years, but still little is known about work disability in occupational cohorts of workers exposed to respiratory irritants. This study investigated job or task changes due to respiratory problems as an indicator of work disability in pulp mill workers occupationally exposed to irritants. Methods Data about respiratory symptoms and disease diagnoses, socio-demographic variables, occupational exposures, gassing episodes, and reported work changes due to respiratory problems were collected using a questionnaire answered by 3226 pulp mill workers. Information about work history and departments was obtained from personnel files. Incidence and hazard ratios for respiratory work disability were calculated with 95% confidence intervals (CI. Results The incidence of respiratory work disability among these pulp mill workers was 1.6/1000 person-years. The hazard ratios for respiratory work disability were increased for workers reporting gassings (HR 5.3, 95% CI 2.7-10.5 and for those reporting physician-diagnosed asthma, chronic bronchitis, and chronic rhinitis, when analyzed in the same model. Conclusions This cohort study of pulp mill workers found that irritant peak exposure during gassing episodes was a strong predictor of changing work due to respiratory problems, even after adjustment for asthma, chronic bronchitis, and chronic rhinitis.

    Full Text Available Abstract Background Gender related differences in respiratory disease have been documented. The aim of this study was to investigate gender related differences in respiratory findings by occupation. We analyzed data from 12 of our previously published studies. Methods Three thousand and eleven (3011 workers employed in "organic dust" industries (1379 female and 1632 male were studied. A control group of 806 workers not exposed to any kind of dust were also investigated (male = 419, female = 387. Acute and chronic respiratory symptoms and lung function were measured. The weighted average method and the Mantel-Haentszel method were used to calculate the odds ratios of symptoms. Hedge's unbiased estimations were used to measure lung function differences between men and women. Results There were high prevalences of acute and chronic respiratory symptoms in all the "dusty" studied groups compared to controls. Significantly less chronic cough, chronic phlegm as well as chronic bronchitis were found among women than among men after the adjustments for smoking, age and duration of employment. Upper respiratory tract symptoms by contrast were more frequent in women than in men in these groups. Significant gender related lung function differences occurred in the textile industry but not in the food processing industry or among farmers. Conclusion The results of this study suggest that in industries processing organic compounds there are gender differences in respiratory symptoms and lung function in exposed workers. Whether these findings represent true physiologic gender differences, gender specific workplace exposures or other undefined gender variables not defined in this study cannot be determined. These data do not suggest that special limitations for women are warranted for respiratory health reasons in these industries, but the issue of upper respiratory irritation and disease warrants further study.

    Background Anxiety and depression are two of the commonest and most modifiable comorbidities of chronic obstructive pulmonary disease (COPD) and have an independent effect on health and prognosis. FEV1% has been shown to be a poor predictor of anxiety and depression. The body mass index, degree of airflow obstruction, dyspnea,and exercise capacity (BODE) index is a multidimensional assessment system which may predict health outcome in COPD patients. The purpose of this study was to investigate the predictive validity of the BODE index for anxious and depressive symptoms in COPD patients.Methods This was a multicenter prospective cross-sectional study in 256 patients with stable COPD. Anxious and depressive symptoms were assessed using the Hospital Anxiety and Depression Scale (HADS). The relationships between anxiety, depression and potential predictors (including the BODE index) were analyzed by a binary Logistic regression model. Results Subjects who were anxious and depressive walked a shorter six-minute walking distance (6MWD), had more dyspnea, a higher BODE index, and lower health-related quality of life (P <0.01). Anxiety and depression score was significantly correlated with BODE index, respectively (r=0.335, P <0.001; r=0.306, P <0.001). The prevalence of anxiety and depression increased with BODE stage increasing (P <0.05). On the basis of binary Logistic regression, the BODE index was a good and independent predictor of anxiety and depression because it comprised dyspnea and 6MWD, which were shown to be the main determinants.Conclusions The predictive validity of the BODE index for anxiety and depression was demonstrated. We propose that the BODE index should be included in assessment of COPD severity.

  10. Effects of long-term administration of Cilostazol on chronic cerebral circulatory insufficiency. With special reference to cerebral blood flow and clinical symptoms

    International Nuclear Information System (INIS)

    This report deals with a study of the effectiveness, safety, and usefulness of long-term administration of Cilostazol for the improvement of cerebral blood flow and clinical symptoms in 24 patients with Chronic Cerebral Circulatory Insufficiency. Cerebral blood flow was investigated quantitatively using the Patlak plot method. Cilostazol was orally administered for 209 days on average. In the global improvement rating assessed on the basis of all subjective symptoms, the final improvement rate, comprising all cases showing moderate or better improvement, was 52.2%. Regarding individual symptoms, dizziness, orthostatic syncope, dull headache, and headache showed improvement rates of 30% or more. Regional cerebral blood flow (rCBF) was increased in both cerebral and cerebellar hemispheres. The global improvement rating for subjective symptoms and the Δ%rCBF for every region except the cerebral hemispheres were positively correlated. However, there was no positive correlation between the global improvement rating for psychiatric symptoms and the Δ%rCBF for any region. Regarding individual subjective symptoms, dizziness showed an especially high positive correlation of above 0.7 between the improvement rating and the Δ%rCBF in the left temporal lobe, basal ganglia, and cerebellum. Headache was observed as an adverse drug reaction in 8 of 24 patients, but it disappeared with reduction of the dose or discontinuation of administration. No other severe adverse drug reactions were noticed. In summary, it was concluded that Cilostazol was useful for treating chronic cerebral circulatory insufficiency. (author)

    Full Text Available Up to presence chronic respiratory disease (CRD of chickens is still causing economic losses against poultry industries in the world. The purpose of this trial is to determine the efficacy and safety of a compatible dose of Tiamulin hydrogen fumarat 10% in combination with monensin for the control of CRD in broilers. A number of 630 day-old broilers were divided into 3 groups and each group was divided again into 7 subgroups of 30 equally sexed birds. Each subgroup was placed randomly in 2 chicken houses. Up to 3 weeks of age, chickens in Group I were fed with starter feed (SP1 containing 100 ppm monensin only without other treatment and used as control. Chickens in Group II were fed with SP1 feed containing 30 ppm Tiamulin hydrogen fumarat (3 – 6 mg/ kg BW and 110 ppm amoxicillin, this feed is called SP1+, whereas chickens in Group III were administered with SP1 feed and treated with enrofloxacin liquid formulation 10% with a dose 0.5ml/L in drinking water for the first 5 days of life. Started from 22nd day until the end of the experiment at 32 days of age, all chickens in Groups I, II and III were fed with SP2 finisher feed containing neither monensin nor Tiamulin hydrogen fumarat. The results of the experiment showed that no statistical difference in bodyweight and feed conversions among the groups at 32 days of age but feed conversion in Group II was statistically different compared to those in Groups I and III at week 2. No clinical signs of toxic interaction of monensin combined with Tiamulin were observed. Lesions of airsacculitis and ascites occurred only in dead chickens of Groups I and III but not in chickens of Group II. The incidence of pneumonia in Group I occurred in all dead birds which is statistically different to Group II that had one lesion of pneumonia. Mycoplasma gallisepticum and Escherichia coli organisms were able to be isolated from the chickens that had pneumonia and ascites in Groups I and III only. The results of

    Full Text Available The main function of the lungs is to maintain the exchange between the pulmonary capillary and the air in the alveoli. By this way, the arteriel oxygen and carbondioxide tension remains constant. Respiratory failure is a syndrome which is defined as the loss of the ability of respiratory system to exchange oxygen and carbondioxide elimination function. The main pathophysiological causes of respiratory failure include ventilation-perfusion mismatch, alveolar hypoventilation, impaired diffusion capacity and increased shunt. A number of diseases may result in respiratory failure by different pathophysiological reasons. The most common causes are Type 1 (hypoxemic and Type 2 (hypercapnic respiratory failure. When suspected with clinical signs and symptoms, the diagnosis should be confirmed with arterial blood gases. At this step, other diagnostic interventions, which could be performed, may be used to enlighten the underlying pathophysiological cause. Although the main therapeutic approach is similar, specific treatment are also required based on the underlying cause. The basic pathophysiological points, diagnosis and basic treatment approach have been evaluated in this review article. [Cukurova Med J 2014; 39(3.000: 428-442

    Full Text Available Background. Treating functional gastrointestinal disorders is extremely difficult. We herein report the effect of the oral administration of Ninjinto (NJT, ginseng decoction, a traditional Japanese Kampo medicine, on chronic intestinal failure. Patients and Methods. Seven patients with chronic intestinal failure treated with NJT were evaluated in this study. The primary diseases included chronic intestinal pseudoobstruction (CIPO: n=4, short bowel syndrome (SBS: n=2, and intestinal atresia n=1. All patients orally received NJT extract granules at a dose of 0.3 g/kg BW per day. The treatment outcomes were then assessed according to the patients’ symptoms and consecutive abdominal X-ray findings. Results. The targeted symptoms were abdominal distension in four patients, diarrhea in three patients, and frequent hospitalization due to infections in two patients. An improvement in the symptoms was observed in six of the seven patients, whereas one patient with SBS did not show any improvement. An improvement in an abdominal roentgenogram was observed in the four patients with remarkably dilated bowel loops due to CIPO. Conclusions. NJT may be effective in controlling functional gastrointestinal disorders associated with chronic intestinal failure. The use of Kampo medicine in the field of pediatric surgery may help to improve the quality of life in children suffering from such conditions.

    Depressive symptoms have become the most important global public health issue. Iron plays an important role in brain function, cognition, and behavior, and its impacts on depressive symptoms may be multifactorial with both positive and negative effects. Previous observational studies focusing on the association between iron status and depressive symptoms showed inconsistent results. Ferritin is a ubiquitous intracellular protein that can store and release iron and is widely used as a clinical biomarker to evaluate iron status. We performed a cross-sectional study to examine the relationship between serum ferritin and depressive symptoms among 3,839 subjects who were from the Tianjin Chronic Low-grade Systemic Inflammation and Health (TCLSIHealth) cohort. Depressive symptoms were assessed using the Chinese version of 20-item self-rating Depression Scale (SDS) with 4 cutoffs (40, 45, 48 and 50) to indicate elevated depressive symptoms (40 was the primary cut-off). The prevalence of depressive symptoms was 36.5%, 17.6%, 11.0% and 7.0% for SDS ≥40, ≥45, ≥48 and ≥50, respectively. With the primary cut-off point of 40, multiple potential confounding factors were adjusted and the odds ratios (95% confidence interval) of having elevated depressive symptoms by quartiles of serum ferritin concentrations were 1.00 (reference), 1.10 (0.91, 1.34), 0.81 (0.66, 1.01) and 1.02 (0.81, 1.28) for the first, second, third and fourth quartile, respectively (P for trend = 0.76). Similar relations were observed with the use of other cut-offs as a definition of depressive symptoms. In conclusion, there is no significant relationship between serum ferritin concentrations and depressive symptoms among Chinese adults. PMID:27611581

    The Lee Chronic Graft-versus-Host Disease (GVHD) Symptom Scale is a patient-reported instrument developed and validated in English to measure the symptoms and functional impact of cGVHD. This tool has not yet been validated in a Latin American population, however. The Brazil-Seattle Chronic GVHD Consortium conducted a multicenter study at 5 Brazilian institutions to validate the Lee cGVHD Symptom Scale in adults with cGVHD. Study objectives included the translation and validation of the instrument in Brazilian Portuguese and evaluation of the correlation with other quality of life (QoL) tools, including the Medical Outcomes Study Short Form 36 (SF-36) and Functional Assessment of Chronic Illness Therapy with Bone Marrow Transplant subscale (FACT-BMT). Translation and validation were done according to the American Association of Orthopedic Surgeons Outcome Committee guidelines. Spearman's correlation coefficient was used to measure construct validity. Reliability was assessed using Cronbach's α and intraclass correlation coefficients. Between April 2011 and August 2012, 47 patients with cGVHD based on the 2005 National Institutes of Health criteria (29 males [62%], 18 females [38%]; median age, 48 years; range, 23 to 69 years) were enrolled in this study. The reliability of the Lee cGVHD Symptom Scale was adequate (Cronbach's α = 0.62 to 0.83). The correlations between similar domains of the Lee cGVHD Symptom Scale, SF-36, and FACT-BMT were moderate to high. Our data indicate that the Brazilian Portuguese version of the Lee cGVHD Symptom Scale is valid and reliable and can be used in clinical trials of cGVHD in Brazil. PMID:27058616

    To our knowledge there are no studies evaluating the prevalence and characteristics of itch, pain, and burning sensation among patients with mild to moderate chronic venous insufficiency or assessing the impact of these symptoms on quality of life. In this report 100 patients met the inclusion criteria. Patients who suffered from itch were also assessed with the use of a validated questionnaire and a modified Skindex-16 questionnaire. We found that the prevalence of itch was 66%. Concomitant itch and burning sensation as well as itch and pain were noted in 47% and 44% of the patients, respectively. No correlation was noted between the severity of these symptoms and the degree of venous insufficiency. Itch had a negative impact on quality of life. A limitation of this study is that the participants, who were primarily hospital employees, are more likely to develop these symptoms. Therefore this study does not reflect the true prevalence of these symptoms in the general population. This study found that itch, pain, and burning sensation are common symptoms of mild to moderate chronic venous insufficiency with a significant impact on quality of life. PMID:16112363

    BACKGROUND Patients with multisymptom chronic conditions, such as refractory ulcerative colitis (RUC) and chronic fatigue syndrome (CFS), present diagnostic and management challenges for clinicians, as well as the opportunity to recognize and treat emerging disease entities. In the current case we report reversal of co-existing RUC and CFS symptoms arising from biotoxin exposures in a genetically susceptible individual. CASE REPORT A 25-year-old previously healthy male with new-onset refractory ulcerative colitis (RUC) and chronic fatigue syndrome (CFS) tested negative for autoimmune disease biomarkers. However, urine mycotoxin panel testing was positive for trichothecene group and air filter testing from the patient's water-damaged rental house identified the toxic mold Stachybotrys chartarum. HLA-DR/DQ testing revealed a multisusceptible haplotype for development of chronic inflammation, and serum chronic inflammatory response syndrome (CIRS) biomarker testing was positive for highly elevated TGF-beta and a clinically undetectable level of vasoactive intestinal peptide (VIP). Following elimination of biotoxin exposures, VIP replacement therapy, dental extractions, and implementation of a mind body intervention-relaxation response (MBI-RR) program, the patient's symptoms resolved. He is off medications, back to work, and resuming normal exercise. CONCLUSIONS This constellation of RUC and CFS symptoms in an HLA-DR/DQ genetically susceptible individual with biotoxin exposures is consistent with the recently described CIRS disease pathophysiology. Chronic immune disturbance (turbatio immuno) can be identified with clinically available CIRS biomarkers and may represent a treatable underlying disease etiology in a subset of genetically susceptible patients with RUC, CFS, and other immune disorders.

    The human alphacoronaviruses HCoV-NL63 and HCoV-229E are commonly associated with upper respiratory tract infections (URTI). Information on their molecular epidemiology and evolutionary dynamics in the tropical region of southeast Asia however is limited. Here, we analyzed the phylogenetic, temporal distribution, population history, and clinical manifestations among patients infected with HCoV-NL63 and HCoV-229E. Nasopharyngeal swabs were collected from 2,060 consenting adults presented with acute URTI symptoms in Kuala Lumpur, Malaysia, between 2012 and 2013. The presence of HCoV-NL63 and HCoV-229E was detected using multiplex polymerase chain reaction (PCR). The spike glycoprotein, nucleocapsid, and 1a genes were sequenced for phylogenetic reconstruction and Bayesian coalescent inference. A total of 68/2,060 (3.3%) subjects were positive for human alphacoronavirus; HCoV-NL63 and HCoV-229E were detected in 45 (2.2%) and 23 (1.1%) patients, respectively. A peak in the number of HCoV-NL63 infections was recorded between June and October 2012. Phylogenetic inference revealed that 62.8% of HCoV-NL63 infections belonged to genotype B, 37.2% was genotype C, while all HCoV-229E sequences were clustered within group 4. Molecular dating analysis indicated that the origin of HCoV-NL63 was dated to 1921, before it diverged into genotype A (1975), genotype B (1996), and genotype C (2003). The root of the HCoV-229E tree was dated to 1955, before it diverged into groups 1-4 between the 1970s and 1990s. The study described the seasonality, molecular diversity, and evolutionary dynamics of human alphacoronavirus infections in a tropical region. PMID:26928836

    Full Text Available Chronic respiratory disease occurrence in urban population is creating burden on economic growth and challenges to public health management. This descriptive, prevalence study was designed to gather data on risk factor related association of respiratory diseases occurrence with information on sign, symptoms and treatment modalities. Questionnaire based personal interview was conducted on selected patients with well documented respiratory problem on demographic, biosocial, educational, occupational and economic background. Body weight, height, blood pressure, details of treatment modalities, sign and symptoms were recorded from hospital data. The prevalence rates were presented as percentage and 95% confidence interval estimated and analyzed by person’s chi-square test. Age, number of children more than three (p<0.0001, family members more than three (p<0.01, overcrowding (p<0.0001, low socioeconomic class (p<0.0001, unhygienic surrounding (p<0.001, education below secondary level (p<0.01, low to normal BMI (p<0.002 and chronic smoking habit (p<0.001 showed significant risk factor related association with occurrence of respiratory disease. Most frequently found sign and symptom are apnea, tiredness, nausea, coughing and nose tickling. Marital status, source of drinking water, cooking fuel, occupation, employment status, income, respiratory rate, sleep pattern and regular use of other medication does not show any co-relation with respiratory disease occurrence. The significant risk factor for respiratory disease occurrence is aging, unhygienic environment, low level education, overcrowding and smoking.

    This study aims to evaluate the acute effects of an oscillating positive expiratory pressure device (flutter) on airways resistance in patients with chronic obstructive pulmonary disease (COPD).Randomized crossover study: 15 COPD outpatients from Asthma Lab-Royal Brompton Hospital underwent spirometry, impulse oscillometry (IOS) for respiratory resistance (R) and reactance (X), and fraction exhaled nitric oxide (FeNO) measures.Thirty minutes of flutter exercises: a "flutter-sham" procedure was used as a control, and airway responses after a short-acting bronchodilator were also assessed.Respiratory system resistance (R): in COPD patients an increase in X5insp (-0.21 to -0.33 kPa/L/s) and Fres (24.95 to 26.16 Hz) occurred immediately after flutter exercises without bronchodilator. Following 20 min of rest, a decrease in the R5, ΔR5, R20, X5, and Ax was observed, with R5, R20, and X5 values lower than baseline, with a moderate effect size; there were no changes in FeNO levels or spirometry.The use of flutter can decrease the respiratory system resistance and reactance and expiratory flow limitation in stable COPD patients with small amounts of secretions.

    Full Text Available It is common for elderly people and those with such chronic disorders as respiratory diseases to suffer severe complications from influenza, a viral infection. The voluntary uptake of vaccination is vital to the effectiveness of influenza prevention efforts. The Health Belief Model (HBM is the most commonly used framework in the field of vaccination behavior to explain the decision that people make to accept or refuse vaccination. In addition, psychological flexibility is considered helpful in causing people to be open to adopting new practices that are consistent with their values. This study examined the role of psychological flexibility and health beliefs in predicting the uptake of influenza vaccination among people in Hong Kong. Eligible participants were Hong Kong permanent residents aged 18 years or above with a history of chronic respiratory diseases (CRD. A convenience sample of 255 patients was recruited to participate in a cross-sectional survey in which HBM components and factors of psychological flexibility were assessed. The following variables were found to be significant predictors of vaccination: age, smoking status, comorbidity, previous hospitalization, perceived susceptibility, perceived severity, and psychological flexibility. Enhancing psychological flexibility might be a potential new direction for motivating people to accept influenza vaccination.

    Using the 100 office-building Building Assessment Survey and Evaluation (BASE) Study dataset, we performed multivariate logistic regression analyses to quantify the associations between indoor minus outdoor CO{sub 2} (dCO{sub 2}) concentrations and mucous membrane (MM) and lower respiratory system (Lresp) Sick Building Syndrome (SBS) symptoms, adjusting for age, sex, smoking status, presence of carpet in workspace, thermal exposure, relative humidity, and a marker for entrained automobile exhaust. Using principal components analysis we identified a number of possible sources of 73 measured volatile organic compounds in the office buildings, and assessed the impact of these VOCs on the probability of presenting the SBS symptoms. Additionally we included analysis adjusting for the risks for predisposition of having SBS symptoms associated with the allergic, asthmatic, and environmentally sensitive subpopulations within the office buildings. Adjusted odds ratios (ORs) for statistically significant, dose-dependant associations (p<0.05) for dry eyes, sore throat, nose/sinus congestion, and wheeze symptoms with 100-ppm increases in dCO{sub 2} ranged from 1.1 to 1.2. These results suggest that increases in the ventilation rates per person among typical office buildings will, on average significantly reduce the prevalence of several SBS symptoms, up to 80%, even when these buildings meet the existing ASHRAE ventilation standards for office buildings. VOC sources were observed to play an role in direct association with mucous membrane and lower respiratory irritation, and possibly to be indirectly involved in indoor chemical reactions with ozone that produce irritating compounds associated with SBS symptoms. O-xylene, possibly emitted from furniture coatings was associated with shortness of breath (OR at the maximum concentration = 8, p < 0.05). The environmental sensitivities of a large subset of the office building population add to the overall risk of SBS symptoms (ORs

    PURPOSE: Chronic obstructive pulmonary disease (COPD) is characterized by airflow limitation which is not fully reversible. Despite the heterogeneity of COPD, its diagnosis and staging is currently based solely on forced expiratory volume in 1 s (FEV(1)). FEV(1) does not explain the underlying pathophysiology of airflow limitation. The relationship between FEV(1), symptoms and emphysema extent is weak.

    Background Early withdraw from invasive mechanical ventilation (MV) followed by noninvasive MV is a new strategy for changing modes of treatment. This study was conducted to estimate the feasibility and the efficacy of early extubation and sequential noninvasive MV commenced at beginning of pulmonary infection control window in patients with exacerbated hypercapnic respiratory failure caused by chronic obstructive pulmonary diseases (COPD). Methods A prospective, randomized controlled study was conducted in eleven teaching hospitals' respiratory or medical intensive care units in China. Ninety intubated COPD patients with severe hypercapnic respiratory failure triggered by pulmonary infection (pneumonia or purulent bronchitis) were involved in the study. When the pulmonary infection had been controlled by antibiotics and comprehensive therapy, the "pulmonary infection control window (PIC window)" has been reached. Each case was randomly assigned to study group (extubation and noninvasive MV via facial mask immediately) or control group (invasive MV was received continuously after PIC window by using conventional weaning technique).Results Study group (n=47) and control group (n=43) had similar clinical characteristics initially and at the time of PIC window. Compared with control group, study group had shorter duration of invasive MV [(6.4±4.4) days vs (11.3±6.2) days, P=0.000], lower rate of ventilator associated pneumonia (VAP) (3/47 vs 12/43, P=0.014), fewer days in ICU [(12±8) days vs (16±11) days, P=0.047] and lower hospital mortality (1/47 vs 7/43, P=0.025).Conclusions In COPD patients requiring intubation and invasive MV for hypercapnic respiratory failure, which is exacerbated by pulmonary infection, early extubation followed by noninvasive MV initiated at the start of PIC window may decrease significantly the duration of invasive MV, the risk of VAP and hospital mortality.

    Chronic non-specific lung disease (CNSLD) encompasses asthma as well as chronic obstructive pulmonary disease (COPD). Recently in health care, there has been increasing awareness in the functional, psychological and social aspects of the health of patients; their quality of life (QOL). Quality-of-life research addressing CNSLD patients has been rather underdeveloped for a long period of time. Recently, however, the importance of QOL is being increasingly recognized, and several research groups have started to study QOL in CNSLD patients in more detail. This paper describes the construction of a disease-specific QOL instrument for patients with mild to moderately severe CNSLD. Items relating to several domains of QOL were listed, and 171 CNSLD patients in general practice were asked how much of a problem each item had been (assessed on a seven-point Likert scale). After applying an item-selection procedure, a uni-dimensional QOL questionnaire was constructed consisting of 55 items divided into seven domain subscales: breathing problems, physical problems, emotions, situations triggering or enhancing breathing problems, general activities, daily and domestic activities, and social activities, relationships and sexuality. Reliability estimates of the domain subscales of the constructed questionnaire varied from 0.68 to 0.89, and was 0.92 for the QOL for Respiratory Illness Questionnaire (QOL-RIQ) total scale. A first impression of the construct validity of the questionnaire was gained by investigation of the relationship between the QOL domain subscales and several indicators of illness severity, as well as the relative contribution of illness severity variables, background characteristics and symptoms to QOL, using regression analysis. Further research to validate the questionnaire to a greater extent (construct validity, test-retest reliability and responsiveness to change) is currently taking place. PMID:9176649

We aimed to evaluate the effects of only indacaterol and tiotropium monotherapies on airflow limitation and respiratory impedance. Pulmonary function tests, COPD assessment test (CAT, and multifrequency FOT with MostGraph-01 were performed at the beginning and after 8 weeks of treatment with indacaterol or tiotropium. The resistance index, resistance at 5 Hz (R5, resistance at 20 Hz (R20, reactance index, reactance at 5 Hz (X5, resonant frequency (Fres, and low-frequency reactance area (ALX were determined at whole-breath, inspiratory, and expiratory phases. Eighty-two patients (mean age: 73 years; mean forced expiratory volume in 1 second (FEV1: 61.6%±19.0% predicted were randomized to indacaterol or tiotropium treatment. Both bronchodilators improved airflow limitation, with mean trough improvements in FEV1 of 165 mL and 80 mL in the indacaterol and tiotropium groups, respectively. The CAT score decreased in the indacaterol group (P<0.001; 11.2±6.6 to 7.5±5.6. Compared with tiotropium, indacaterol significantly improved FEV1, percent predicted FEV1, and CAT score (P=0.042, P=0.008, and P=0.027, respectively. For respiratory impedance, indacaterol and tiotropium changed R5, X5, Fres, and ALX at whole-breath, inspiratory, and expiratory phases. In the indacaterol group, the changes in R5, R5–R20, X5, Fres, and ALX were significantly correlated

  1. Psychiatric and subjective symptoms and cerebral blood flow in patients with chronic cerebral infarction after treatment with Ca antagonist (nilvadipine). Quantitative measurement of cerebral blood flow by the 123IMP-SPECT ARG method

    International Nuclear Information System (INIS)

    Psychiatric and subjective symptoms such as headache, dizziness, lack of spontaneity, anxiety, and a depressive state are often found in patients with chronic cerebral infarction. Some Ca antagonists are reported to relieve such symptoms. The purpose of the present study was to investigate the relationship between psychiatric and subjective symptoms and cerebral blood flow (CBF) in cerebral infarction and to evaluate the clinical effects of Ca antagonists from the standpoint of the cerebral circulation. Nilvadipine was administered to is patients with chronic cerebral infarction and their CBF was measured by the 123IMP-SPECT ARG method before and at 8 weeks after the nilvadipine treatment. The CBF in patients with hypertension was increased by 11% after giving nilvadipine. Patients without hypertension showed no tendency for elevation of their CBF. Patients who were relieved from some psychiatric symptoms revealed a 14% increase of CBF in all cortical regions, and a significant increase was noted in the frontal and temporal regions. In other patients without changes in psychiatric symptoms, the CBF did not increase in any of the cortical regions. No relationship between symptoms and CBF was observed in any of the patients with subjective symptoms. Our study demonstrated a close correlation between psychiatric symptoms and CBF. We speculate that psychiatric symptoms in chronic cerebral infarction may reflect diffuse brain dysfunctions. We also conclude that nilvadipine is more effective in relieving psychiatric symptoms in patients with hypertensive cerebral infarction. It is inferred that nilvadipine may be more effective in relieving psychiatric symptoms in patients with hypertension. (author)

    Full Text Available Poloxamer 188 NF (national formulary (NF grade of P-188 improves cardiac muscle function in the mdx mouse and golden retriever muscular dystrophy models. However in vivo effects on skeletal muscle have not been reported. We postulated that P-188 NF might protect diaphragm muscle membranes from contraction-induced injury in mdx and mdx/utrophin-/- (dko muscular dystrophy models. In the first study 7-month old mdx mice were treated for 22 weeks with subcutaneous (s.c. injections of saline or P-188 NF at 3 mg/Kg. In the second, dkos were treated with saline or P-188 NF (1 mg/Kg for 8 weeks beginning at age 3 weeks. Prednisone was the positive control in both studies. Respiratory function was monitored using unrestrained whole body plethysmography. P-188 NF treatment affected several respiratory parameters including tidal volume/BW and minute volume/BW in mdx mice. In the more severe dko model, P-188 NF (1 mg/Kg significantly slowed the decline in multiple respiratory parameters compared with saline-treated dko mice. Prednisone's effects were similar to those seen with P-188 NF. Diaphragms from P-188 NF or prednisone treated mdx and dko mice showed signs of muscle fiber protection including less centralized nuclei, less variation in fiber size, greater fiber density, and exhibited a decreased amount of collagen deposition. P-188 NF at 3 mg/Kg s.c. also improved parameters of systolic and diastolic function in mdx mouse hearts. These results suggest that P-188 NF may be useful in treating respiratory and cardiac dysfunction, the leading causes of death in Duchenne muscular dystrophy patients.

    Full Text Available Helmy Haja Mydin, Stephen Murphy, Howell Clague, Kishore Sridharan, Ian K TaylorDepartment of Respiratory Medicine, Sunderland Royal Infirmary, Sunderland, United KingdomBackground: In patients with acute hypercapnic respiratory failure (AHRF during exacerbations of COPD, mortality can be high despite noninvasive ventilation (NIV. For some, AHRF is terminal and NIV is inappropriate. However there is no definitive method of identifying patients who are unlikely to survive. The aim of this study was to identify factors associated with inpatient mortality from AHRF with respiratory acidosis due to COPD.Methods: COPD patients presenting with AHRF and who were treated with NIV were studied prospectively. The forced expiratory volume in 1 second (FEV1, World Health Organization performance status (WHO-PS, clinical observations, a composite physiological score (Early Warning Score, routine hematology and biochemistry, and arterial blood gases prior to commencing NIV, were recorded.Results: In total, 65 patients were included for study, 29 males and 36 females, with a mean age of 71 ± 10.5 years. Inpatient mortality in the group was 33.8%. Mortality at 30 days and 12 months after admission were 38.5% and 58.5%, respectively. On univariate analysis, the variables associated with inpatient death were: WHO-PS ≥ 3, long-term oxygen therapy, anemia, diastolic blood pressure < 70 mmHg, Early Warning Score ≥ 3, severe acidosis (pH < 7.20, and serum albumin < 35 g/L. On multivariate analysis, only anemia and WHO-PS ≥ 3 were significant. The presence of both predicted 68% of inpatient deaths, with a specificity of 98%.Conclusion: WHO-PS ≥ 3 and anemia are prognostic factors in AHRF with respiratory acidosis due to COPD. A combination of the two provides a simple method of identifying patients unlikely to benefit from NIV.Keywords: acute exacerbations of COPD, noninvasive ventilation, emphysema, prognostic markers

    Laboratory and observational research studies suggest that vitamin D and marine omega-3 fatty acids may reduce risk for pneumonia, acute exacerbations of respiratory diseases including chronic obstructive lung disease (COPD) or asthma, and decline of lung function, but prevention trials with adequate dosing, adequate power, and adequate time to follow-up are lacking. The ongoing Lung VITAL study is taking advantage of a large clinical trial-the VITamin D and OmegA-3 TriaL (VITAL)-to conduct the first major evaluation of the influences of vitamin D and marine omega-3 fatty acid supplementation on pneumonia risk, respiratory exacerbation episodes, asthma control and lung function in adults. VITAL is a 5-yearU.S.-wide randomized, double-blind, placebo-controlled, 2×2 factorial trial of supplementation with vitamin D3 ([cholecalciferol], 2000IU/day) and marine omega-3 FA (Omacor® fish oil, eicosapentaenoic acid [EPA]+docosahexaenoic acid [DHA], 1g/day) for primary prevention of CVD and cancer among men and women, at baseline aged ≥50 and ≥55, respectively, with 5107 African Americans. In a subset of 1973 participants from 11 urban U.S. centers, lung function is measured before and two years after randomization. Yearly follow-up questionnaires assess incident pneumonia in the entire randomized population, and exacerbations of respiratory disease, asthma control and dyspnea in a subpopulation of 4314 randomized participants enriched, as shown in presentation of baseline characteristics, for respiratory disease, respiratory symptoms, and history of cigarette smoking. Self-reported pneumonia hospitalization will be confirmed by medical record review, and exacerbations will be confirmed by Center for Medicare and Medicaid Services data review. PMID:26784651

    Farmers are occupationally exposed to many respiratory hazards at work and display higher rates of asthma and respiratory symptoms than other workers. Dust is one of the components present in poultry production that increases risk of adverse respiratory disease occurrence. Dust originates from poultry residues, molds, and feathers and is biologically active as it contains microorganisms. Exposure to dust is known to produce a variety of clinical responses, including asthma, chronic bronchitis, chronic airways obstructive disease (COPD), allergic alveolitis, and organic dust toxic syndrome (ODTS). A study was developed to determine particle contamination in seven poultry farms and correlate this with prevalence rate of respiratory defects and record by means of a questionnaire the presence of clinical symptoms associated with asthma and other allergy diseases by European Community Respiratory Health Survey. Poultry farm dust contamination was found to contain higher concentrations of particulate matter (PM) PM5 and PM10. Prevalence rate of obstructive pulmonary disorders was higher in individuals with longer exposure regardless of smoking status. In addition, a high prevalence for asthmatic (42.5%) and nasal (51.1%) symptoms was noted in poultry workers. Data thus show that poultry farm workers are more prone to suffer from respiratory ailments and this may be attributed to higher concentrations of PM found in the dust. Intervention programs aimed at reducing exposure to dust will ameliorate occupational working conditions and enhance the health of workers. PMID:23514065

    To examine hypotheses regarding health effects of particulate matter, we conducted time series studies in Austrian urban and rural areas. Of the pollutants measured, ambient PM 2.5 was most consistently associated with parameters of respiratory health. Time series studies applying semiparametric generalized additive models showed significant increases of respiratory hospital admissions (ICD 490-496) at age 65 and older. The early increase of 5.5% in Vienna at a lag of 2 days in males and of 5.6% per 10 μg/m 3 at a lag of 3 days in females was not observed in a nearby rural area. Another increase of respiratory admissions (mainly COPD) was observed after a lag of 10-11 days. A time series on a panel of 56 healthy preschool children showed a significant impact of the carbonaceous fraction of PM 2.5 on tidal breathing pattern assessed by inductive plethysmography. In repeated oscillometric measurements of respiratory resistance in 164 healthy elementary school children not only immediate responses to fine particulates were found but also latent ones, possibly indicating inflammatory changes in airways. It may be speculated that the improvements of urban air quality prevented measurable effects on respiratory mortality. More sensitive indicators, however, still show acute impairments of respiratory function and health in elderly and children which are associated with fine particulates and subfractions related to motor traffic.

    Purpose: To investigate the incorporation of functional lung image-derived low attenuation area (LAA) based on four-dimensional computed tomography (4D-CT) into respiratory-gated intensity-modulated radiotherapy (IMRT) or volumetric modulated arc therapy (VMAT) in treatment planning for lung cancer patients with chronic obstructive pulmonary disease (COPD). Methods and Materials: Eight lung cancer patients with COPD were the subjects of this study. LAA was generated from 4D-CT data sets according to CT values of less than than -860 Hounsfield units (HU) as a threshold. The functional lung image was defined as the area where LAA was excluded from the image of the total lung. Two respiratory-gated radiotherapy plans (70 Gy/35 fractions) were designed and compared in each patient as follows: Plan A was an anatomical IMRT or VMAT plan based on the total lung; Plan F was a functional IMRT or VMAT plan based on the functional lung. Dosimetric parameters (percentage of total lung volume irradiated with {>=}20 Gy [V20], and mean dose of total lung [MLD]) of the two plans were compared. Results: V20 was lower in Plan F than in Plan A (mean 1.5%, p = 0.025 in IMRT, mean 1.6%, p = 0.044 in VMAT) achieved by a reduction in MLD (mean 0.23 Gy, p = 0.083 in IMRT, mean 0.5 Gy, p = 0.042 in VMAT). No differences were noted in target volume coverage and organ-at-risk doses. Conclusions: Functional IGRT planning based on LAA in respiratory-guided IMRT or VMAT appears to be effective in preserving a functional lung in lung cancer patients with COPD.

    International Nuclear Information System (INIS)

    Purpose: To investigate the incorporation of functional lung image-derived low attenuation area (LAA) based on four-dimensional computed tomography (4D-CT) into respiratory-gated intensity-modulated radiotherapy (IMRT) or volumetric modulated arc therapy (VMAT) in treatment planning for lung cancer patients with chronic obstructive pulmonary disease (COPD). Methods and Materials: Eight lung cancer patients with COPD were the subjects of this study. LAA was generated from 4D-CT data sets according to CT values of less than than −860 Hounsfield units (HU) as a threshold. The functional lung image was defined as the area where LAA was excluded from the image of the total lung. Two respiratory-gated radiotherapy plans (70 Gy/35 fractions) were designed and compared in each patient as follows: Plan A was an anatomical IMRT or VMAT plan based on the total lung; Plan F was a functional IMRT or VMAT plan based on the functional lung. Dosimetric parameters (percentage of total lung volume irradiated with ≥20 Gy [V20], and mean dose of total lung [MLD]) of the two plans were compared. Results: V20 was lower in Plan F than in Plan A (mean 1.5%, p = 0.025 in IMRT, mean 1.6%, p = 0.044 in VMAT) achieved by a reduction in MLD (mean 0.23 Gy, p = 0.083 in IMRT, mean 0.5 Gy, p = 0.042 in VMAT). No differences were noted in target volume coverage and organ-at-risk doses. Conclusions: Functional IGRT planning based on LAA in respiratory-guided IMRT or VMAT appears to be effective in preserving a functional lung in lung cancer patients with COPD.

    Full Text Available Introduction: The majority of Indian hospitals do not provide intensive care unit (ICU care or ward-based noninvasive positive pressure ventilation (NIV. Because no mechanical ventilation or NIV is available in these hospitals, the majority of patients suffering from respiratory failure die. Objective: To perform a cost-effective analysis of two strategies (ward-based NIV with concurrent standard treatment vs standard treatment alone in chronic obstructive pulmonary disease (COPD respiratory failure patients treated in Indian hospitals without ICU care. Materials and Methods: A decision-analytical model was created to compare the cost-effectiveness for the two strategies. Estimates from the literature were used for parameters in the model. Future costs were discounted at 3%. All costs were reported in USD (2012. One-way, two-way, and probabilistic sensitivity analysis were performed. The time horizon was lifetime and perspective was societal. Results: The NIV strategy resulted in 17.7% more survival and was slightly more costly (increased cost of $101 (USD 2012 but resulted in increased quality-adjusted life-years (QALYs (1.67 QALY. The cost-effectiveness (2012 USD/QALY in the standard and NIV groups was $78/QALY ($535.02/6.82 and $75/QALY ($636.33/8.49, respectively. Incremental cost-effectiveness ratio (ICER was only $61 USD/QALY. This was substantially lower than the gross domestic product (GDP per capita for India (1489 USD, suggesting the NIV strategy was very cost effective. Using a 5% discount rate resulted in only minimally different results. Probabilistic analysis suggests that NIV strategy was preferred 100% of the time when willingness to pay was >$250 2012 USD. Conclusion: Ward-based NIV treatment is cost-effective in India, and may increase survival of patients with COPD respiratory failure when ICU is not available.

    The health effects associated with Asian dust have attracted attention due to the rapid increase in the number of Asian dust events in East Asia in recent years. The aim of this study was to investigate the associations between Asian dust and daily cough, as well as allergic symptoms, in adult patients who suffer from chronic cough. We enrolled 86 adult patients from Kanazawa University Hospital, Japan, who were diagnosed with asthma, cough variant asthma, atopic cough or a combination of these conditions. From January to June 2011, subjects recorded their symptoms in a diary every day. Asian dust and non-Asian dust periods were defined according to the dust extinction coefficient, measured using the light detection and ranging (LIDAR). The daily levels of total suspended particulates, polycyclic aromatic hydrocarbons (PAHs) and coexisting factors related to allergies, such as the Japanese cedar pollen count, were measured. McNemar's test showed that there were significantly more cough-positive patients during Asian dust periods than during the non-Asian dust period (p = 0.022). In addition, during Asian dust periods when the daily levels of Japanese cedar pollen, Japanese cypress pollen and PAHs were elevated, there were significantly more patients who experienced itchy eyes than during the non-Asian dust period (p cough and allergic symptoms in adult patients with chronic cough.

    The aim of the study is to determine the inter-reliability and intra-observer reliability of magnetic resonance imaging (MRI) for lateral epicondylitis and investigate whether there is a potential relationship between MRI abnormalities of the common extensor tendon (CET) and its clinical symptom.The study group comprised 96 consecutive patients (46 men and 50 women) with a clinical diagnosis of chronic lateral epicondylitis, which were examined on 3.0 T MR. An MRI scoring system was used to grade the degree of tendinopahty. Three independent musculoskeletal radiologists, who were blinded to the patients' clinical information, scored images separately. Clinical symptoms were assessed using the Patient-Rated Tennis Elbow Evaluation (PRTEE).Of all the patients, total 96 elbows had MRI-assessed tendinopathy, including 38 (39.6%) with grade 1, 31 (32.3%) with grade 2, and 27 (28.1%) with grade 3. Inter-observer reliability and intra-observer agreement for MRI interpretation of the grades of tendinopathy was good, and a positive correlation between the grades of tendinopathy and PRTEE was determined.MRI is a reliable tool in determining radiological severity of chronical lateral epicondylitis. The severity of MR signal changes positively correlate with the patient's clinical symptom. PMID:26844506

    The Visual Simplified Respiratory Questionnaire (VSRQ) was designed to assess health-related quality of life (HRQoL) in patients with chronic obstructive pulmonary disease (COPD). It contains eight items: dyspnea, anxiety, depressed mood, sleep, energy, daily activities, social activities and sexual life. Psychometric properties were assessed during a clinical trial that evaluated the impact of tiotropium on HRQoL of COPD patients. These included the determination of structure, internal consistency reliability, concurrent validity with the St George's Respiratory Questionnaire (SGRQ), test - retest reliability, clinical validity and responsiveness to change over two weeks. Minimal important difference (MID) was calculated; cumulative response curves (CRC) were based on the dyspnea item. Psychometric analyses showed that VSRQ structure was unidimensional. The questionnaire demonstrated good internal consistency reliability (Cronbach's alpha = 0.84), good concurrent validity with SGRQ (Spearman = -0.70) and clinical validity, good test-retest reproducibility (ICC = 0.77), and satisfactory responsiveness (standardized response mean = 0.57; Guyatt's statistic = 0.63). MID was 3.4; CRC median value of the 'minimally improved' patients was 3.5. In conclusion, VSRQ brevity and satisfactory psychometric properties make it a good candidate for large studies to assess HRQoL in COPD patients. Further validation is needed to extend its use in clinical practice. PMID:19436682

    Clinical signs of upper respiratory tract infection can be hard to manage in cats, particularly those in shelters. In this study, clinical data were collected from chronically ill (3-4 weeks' duration) cats with suspected feline herpesvirus-1 (FHV-1) or feline calicivirus (FCV) infections after administration of one of two novel therapies. Group A cats were administered a commercially available formulation of human interferon-α2b at 10,000 U/kg subcutaneously for 14 days, and group B cats were administered one dose of a FHV-1 and FCV intranasal vaccine. Molecular assays for FHV-1 and FCV were performed on pharyngeal samples, and a number of cytokines were measured in the blood of some cats. A clinical score was determined daily for 14 days, with cats that developed an acceptable response by day 14 returning to the shelter for adoption. Those failing the first treatment protocol were entered into the alternate treatment group. During the first treatment period, 8/13 cats in group A (61.5%) and all 12 cats in group B (100%) had apparent responses. The seven cats positive for nucleic acids of FHV-1 or FCV responded favorably, independent of the treatment group. There were no differences in cytokine levels between cats that responded to therapy or failed therapy. Either protocol assessed here may be beneficial in alleviating chronic clinical signs of suspected feline viral upper respiratory tract disease in some cats that have failed other, more conventional, therapies. The results of this study warrant additional research involving these protocols. PMID:26269455

  15. Study of the usefulness of 133Xe pulmonary ventilation scintigraphy in infants having persistent respiratory distress syndrome (chronic lung disease)

    International Nuclear Information System (INIS)

    Twelve infants with chronic lung disease, 7 of bronchopulmonary dysplasia (BPD) and 5 of Wilson-Mikity syndrome, underwent 133Xe pulmonary ventilation scintigraphy. The examination was carried out in safety and diagnostic image was obtained in all cases. In BPD, 4 cases were demonstrated air trapping by ventilation scintigraphy but only 2 cases were demonstrated emphysema by chest X-ray film. In Wilson-Mikity syndrome, 4 cases were demonstrated emphysema by ventilation scintigraphy and chest X-ray film. In infants, chest X-ray film was difficult to confirm emphysema, so that 133Xe ventilation scintigraphy was valuable to estimate chronic lung disease. (author)

    Psychological factors have been found to be of major importance for the transition from acute to chronic low back pain (CLBP). Although some evidence has been provided that depressive symptoms occur secondarily to CLBP, psychological treatment modules that specifically address depressive symptoms are not yet included in German inpatient rehabilitation programs. In this study, a standard rehabilitation program for patients with CLBP and depressive symptoms was compared to a standard rehabilita...

    Beneficial effects on psychological measures in orthopedic inpatient rehabilitation of patients with chronic low back pain (CLBP) and co-exist-ing depressive symptoms have been shown only for multidisciplinary approaches that incorporate psychotherapeutic interventions. Aim of this study was to verify these findings for pain coping outcomes (pain-related psychological disability, pain-related coping). Short-, mid-, and long-term effects of a standard pain management program that was either solely provided or combined with a supplemental cognitive-behavioral depression management were examined in a consecutive sample of n=84. Patients in both groups showed long-term beneficial effects in pain coping measures. Thus, the standard rehabilitation revealed specific and long-term effects on pain coping. However, further evidence suggests that diagnosis-specific psychotherapeutic treatment elements are required to improve psychological symptoms. PMID:24838435

    AIM: To study the predictive value of the vegetativedepressive symptoms of the Zung Depression Rating Scale for the occurrence of depression during treatment with peg-interferon α-2b of chronic hepatitis C (CHC)patients.METHODS: The predictive value of vegetativedepressive symptoms at 4 wk of treatment for the occurrence of a subsequent diagnosis of major depressive disorder (MDD) was studied in CHC patients infected after substance use in a prospective, multicenter treatment trial in Belgium. The presence of vegetative-depressive symptoms was assessed using the Zung Scale before and 4 wk after the start of antiviral treatment.RESULTS: Out of 49 eligible patients, 19 (39%)developed MDD. The area under the ROC curve of the vegetative Zung subscale was 0.73, P = 0.004. The sensitivity at a cut-point of > 15/35 was 95% (95% CI:74-100). The positive predictive value equalled 44% (95%CI: 29-60).CONCLUSION: In this group of Belgian CHC patients infected after substance use, antiviral treatment caused a considerable risk of depression. Seven vegetativedepressive symptoms of the Zung scale at wk 4 of treatment predicted 95% of all emerging depressions, at a price of 56% false positive test results.

    Respiration is the main reason of the chest movements. However, there are also non-respiratory ones, resulting from e.g. snoring, wheezing, stridor, throat clearing or coughing. They may exist sporadically, however should be examined in case when their incidences increase. Detecting non-respiratory movements is very important, because many of them are symptoms of respiratory diseases such as asthma, chronic obstructive pulmonary disease (COPD) or lung cancer. Assessment of the presence of non-respiratory movements could be important element of effective diagnosis. It is also necessary to provide quantitative and objective results for intra-subject studies. Most of these events generate vibroacoustic signals that contain components of sound and vibrations. This work provides the review of the solutions and devices for monitoring of the non-respiratory movements, primarily considering the accuracy of the chest movements' detection and distinguishing.

    Full Text Available CANOMAD is a rare chronic neuropathy, characterized by chronic sensory ataxia and intermittent brain stem symptoms due to antidisialosyl antibodies. The disorder results in significant morbidity but is poorly understood and often misdiagnosed. We describe a unique case of CANOMAD, associated with involuntary movements of the face; patient reported exacerbations with citrus and chocolate and respiratory muscle weakness. Our patient was initially misdiagnosed with Miller Fisher Syndrome, highlighting the need for vigilance should neurological symptoms recur in patients initially diagnosed with a Guillain Barre variant. Moreover, the optimal treatment is unknown. This patient responded remarkably to intravenous immunoglobulin and has been maintained on this treatment, without further exacerbations.

    Chronic lung diseases, such as cystic fibrosis (CF), asthma, and chronic obstructive pulmonary disease (COPD) are incurable and represent a very high social burden. Stem cell-based treatment may represent a hope for the cure of these diseases. In this paper, we revise the overall knowledge about the plasticity and engraftment of exogenous marrow-derived stem cells into the lung, as well as their usefulness in lung repair and therapy of chronic lung diseases. The lung is easily accessible and the pathophysiology of these diseases is characterized by injury, inflammation, and eventually by remodeling of the airways. Bone marrow-derived stem cells, including hematopoietic stem/progenitor cells (HSPCs) and mesenchymal stromal (stem) cells (MSCs), encompass a wide array of cell subsets with different capacities of engraftment and injured tissue regenerating potential. Proof-of-principle that marrow cells administered locally may engraft and give rise to specialized epithelial cells has been given, but the efficiency of this conversion is too limited to give a therapeutic effect. Besides the identification of plasticity mechanisms, the characterization/isolation of the stem cell subpopulations represents a major challenge to improving the efficacy of transplantation protocols used in regenerative medicine for lung diseases.

    A 78 year old Japanese woman was transferred to our hospital for the treatment of a fracture of the left femoral neck in April, 2010. She had been taking oral corticosteroid (prednisolone 5 mg/day) for the treatment of idiopathic interstitial pneumonia since 2003, and had been treated by home oxygen therapy since 2007. She fell in the restroom at home and hurt herself, and was transferred to our hospital for treatment of a left femoral neck fracture in April, 2010. Her respiratory status was stable just after the transfer; however, she was transferred to the intensive care unit and started to receive mechanical ventilation due to rapidly progressive respiratory failure on the fourth day after admission. Chest X-ray and computed tomography revealed rapid progression of bilateral ground-glass attenuations, and acute exacerbation of interstitial pneumonia was clinically suspected. However, the elevation of D-dimer over time and characteristic findings of petechial hemorrhagic lesions on her palpebral conjunctivae and neck with microscopic findings of phagocytized lipid in alveolar macrophages in her endobronchial secretion led to the diagnosis of fat embolism syndrome. She was successfully treated with high-dose corticosteroid and sivelestat sodium, and she was discharged on the 21st day after admission. Although a differential diagnosis of acute exacerbation of interstitial pneumonia and fat embolism syndrome was necessary and difficult in the present case, characteristic findings of petechial hemorrhagic lesions of skin, palpebral conjunctiva and lipid-laden alveolar macrophages in endotracheal aspirate were useful for the accurate and prompt diagnosis of fat embolism syndrome.

    Full Text Available Abstract Background Recent research shows that the prevalence of patients with very severe chronic obstructive pulmonary disease (COPD, congestive heart failure (CHF and chronic renal failure (CRF continues to rise over the next years. Scientific studies concerning self-perceived symptoms and care needs in patients with severe to very severe COPD, CHF and CRF are scarce. Consequently, it will be difficult to develop an optimal patient-centred palliative care program for patients with end-stage COPD, CHF or CRF. The present study has been designed to assess the symptoms, care needs, end-of-life care treatment preferences and communication needs of patients with severe to very severe COPD, CHF or CRF. Additionally, family distress and care giving burden of relatives of these patients will be assessed. Methods/design A cross-sectional comparative and prospective longitudinal study in patients with end-stage COPD, CHF or CRF has been designed. Patients will be recruited by their treating physician specialist. Patients and their closest relatives will be visited at baseline and every 4 months after baseline for a period of 12 months. The following outcomes will be assessed during home visits: self-perceived symptoms and care needs; daily physical functioning; general health status; end-of-life care treatment preferences; end-of-life care communication and care-giver burden of family caregivers. Additionally, end-of-life care communication and prognosis of survival will be assessed with the physician primarily responsible for the management of the chronic organ failure. Finally, if patients decease during the study period, the baseline preferences with regard to life-sustaining treatments will be compared with the real end-of-life care. Discussion To date, the symptoms, care needs, caregiver burden, end-of-life care treatment preferences and communication needs of patients with very severe COPD, CHF or CRF remain unknown.

    Full Text Available Abstract Background In Low and Middle Income Countries, mental health services are often poorly developed due to the lack of resources and trained personnel. In order to overcome these challenges, new ways of care have been suggested such as a focus on community-based services. In Somalia, the consumption of the natural stimulant khat is highly prevalent, aggravating mental illness. At the same time, mental health care is largely unavailable to the vast majority of the population. In a pilot project, we tested possibilities for effective measures in community-based out-patient mental health care. Methods Thirty-five male patients with chronic psychotic disorders and their carers were involved in a 10-months follow-up study. All of them abused khat. Seventeen outpatients experiencing acute psychotic episodes were recruited from the community and received an intensive six week home-based treatment package. Additionally eighteen patients with chronic psychotic disorders in remission were recruited either following hospital discharge or from the community. In a second phase of the study, both groups received community-based relapse prevention that differed in the degree of the family’s responsibility for the treatment. The treatment package was comprised of psycho-education, low-dose neuroleptic treatment, monthly home visits and counseling. The Brief Psychiatric Rating Scale (BPRS was applied three times. Additionally, we assessed functioning, khat use and other outcomes. Results Of the 35 patients enrolled in the study, 33 participated in the 10-month follow-up. Outpatients improved significantly in the first six weeks of treatment and did not differ from remitted patients at the start of the second treatment phase. In the preventive treatment phase, we find heterogeneous outcomes that diverge between symptom and functioning domains. With the exception of depressive symptoms, symptoms in all patients tended to worsen. The outpatient group had

It proved to reduce the need of endotracheal intubation (ETI, the incidence of ETI-associated pneumonia, and mortality compared to nonventilated patients. A particular aspect concerns the outcome of NIMV in patients referring to an emergency room (ER for ARF, and with a do-not-intubate (DNI status due to advanced age or critical conditions. The aim of our study is to assess the outcome of NIMV in a group of elderly patients with acute hypercapnic ARF who had a DNI status. An overall number of 62 subjects (30 males, 32 females, mean age 81 ± 4.8 years, range 79–91 years referred to our semi-intensive respiratory department were enrolled in the study. The underlying diseases were severe chronic obstructive pulmonary disease (COPD in 50/62 subjects, restrictive thoracic disorders in 7/62 subjects, and multiorgan failure in 5/62 subjects. Fifty-four/62 patients were successfully treated with NIMV while 2/62 did not respond to NIMV and were therefore submitted to ETI (one survived. Among NIMV-treated patients, death occurred in 6 patients after a mean of 9.9 days; the overall rate of NIMV failure was 12.9%. Negative prognostic factors for NIMV response

Depressive symptoms were assessed using the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (SCID and a self-report inventory (Hospital Anxiety and Depression Scale [HADS]. A comprehensive clinical dataset, including left ventricular ejection fraction, peak oxygen uptake, and a 6-minute walk test, was obtained for all patients. Neuropsychological functioning revealed impairment in 56% of patients in at least one measure of our neuropsychological test battery. However, the Mini Mental State Examination (MMSE could only detect cognitive impairment in 1.8% of all patients, 24% had HADS scores indicating depressive symptoms, and 11.1% met SCID criteria for a depressive disorder. No significant association was found

  16. Statistical parametric mapping analysis of the relationship between regional cerebral blood flow and symptom clusters of the depressive mood in patients with pre-dialytic chronic kidney disease

    International Nuclear Information System (INIS)

    The aim of this study is to investigate the relationship between regional cerebral blood flow (rCBF) and symptom clusters of depressive mood in pre-dialytic chronic kidney disease (CKD). Twenty-seven patients with stage 4-5 CKD were subjected to statistical parametric mapping analysis of brain single-photon emission computed tomography. Correlation analyses between separate symptom clusters of depressive mood and rCBF were done. The first factor (depressive mood) was negatively correlated with rCBF in the right insula, posterior cingulate gyrus, and left superior temporal gyrus, and positively correlated with rCBF in the left fusiform gyrus. The second factor (insomnia) was negatively correlated with rCBF in the right middle frontal gyrus, bilateral cingulate gyri, right insula, right putamen, and right inferior parietal lobule, and positively correlated with rCBF in left fusiform gyrus and bilateral cerebellar tonsils. The third factor (anxiety and psychomotor aspects) was negatively correlated with rCBF in the left inferior frontal gyms, right superior frontal gyms, right middle temporal gyrus, right superior temporal gyrus, and left superior frontal gyrus, and positively correlated with rCBF in the right ligual gyrus and right parahippocampal gyrus. In this study, the separate symptom clusters were correlated with specific rCBF patterns similar to those in major depressive disorder patients without CKD. However, some areas with discordant rCBF patterns were also noted when compared with major depressive disorder patients. Further larger scale investigations are needed. (author)

    patients with chronic widespread pain (CWP). The aims of the study were to assess the patient-reported sensory neuropathic symptoms by PDQ and to correlate these with tender point (TP) count and pressure-pain thresholds. Eighty-one patients (75 F, 6 M) with CWP (ACR-criteria) filled in the PDQ. Manual TP...... examination was conducted according to ACR guidelines. Computerized cuff pressure algometry was used for the assessment of pressure-pain detection thresholds (PDT, unit: kPa) and pressure-pain tolerance thresholds (PTT, unit: kPa). Mean TP count was 14.32 (range: 2-18), mean PDQ score 22.75 (range: 5......-37). Mean PDT was 8.8 kPa (range: 2-36) and mean PTT 30.9 kPa (range: 4-85). Deep-tissue hyperalgesia was the predominant somatosensory symptom reported in 83%, but other neuropathic symptoms were also frequent, e.g. burning 51% and prickling 47%. Statistically significant correlations were found between...

    Full Text Available Abstract Background Assessment of health-related quality of life (HRQL is important in patients with chronic obstructive pulmonary disease (COPD. Despite the high prevalence of COPD in Germany, Switzerland and Austria there is no validated disease-specific instrument available. The objective of this study was to translate the Chronic Respiratory Questionnaire (CRQ, one of the most widely used respiratory HRQL questionnaires, into German, develop an interviewer- and self-administered version including both standardised and individualised dyspnoea questions, and validate these versions in two randomised studies. Methods We recruited three groups of patients with COPD in Switzerland, Germany and Austria. The 44 patients of the first group completed the CRQ during pilot testing to adapt the CRQ to German-speaking patients. We then recruited 80 patients participating in pulmonary rehabilitation programs to assess internal consistency reliability and cross-sectional validity of the CRQ. The third group consisted of 38 patients with stable COPD without an intervention to assess test-retest reliability. To compare the interviewer- and self-administered versions, we randomised patients in groups 2 and 3 to the interviewer- or self-administered CRQ. Patients completed both the standardised and individualised dyspnoea questions. Results For both administration formats and all domains, we found good internal consistency reliability (Crohnbach's alpha between 0.73 and 0.89. Cross-sectional validity tended to be better for the standardised compared to the individualised dyspnoea questions and cross-sectional validity was slightly better for the self-administered format. Test-retest reliability was good for both the interviewer-administered CRQ (intraclass correlation coefficients for different domains between 0.81 and 0.95 and the self-administered format (intraclass correlation coefficients between 0.78 and 0.86. Lower within-person variability was

    Chronic cough can be the sole presenting symptom for patients with obstructive sleep apnoea. We investigated the prevalence, severity and factors associated with chronic cough in patients with sleep-disordered breathing (SDB). We invited 108 consecutive patients who had been referred for evaluation of SDB to complete a comprehensive questionnaire on respiratory and sleep health, which included the Leicester Cough Questionnaire (cough specific quality of life; LCQ), Epworth Sleepiness Scale (ESS) and the Mayo Clinic gastro-oesophageal questionnaire. Chronic cough was defined as cough for a duration of >2 months. 33% of patients with SDB reported a chronic cough. Patients with a chronic cough had impaired cough related-quality of life affecting all health domains (mean+/-sem LCQ score 17.7+/-0.7; normal = 21). Patients with SDB and chronic cough were predominantly females (61% versus 17%; p<0.001) and reported more nocturnal heartburn (28% versus 5%; p = 0.03) and rhinitis (44% versus 14%; p = 0.02) compared to those without SDB. There were no significant differences in ESS, respiratory disturbance index, body mass index, or symptoms of breathlessness, wheeze, snoring, dry mouth and choking between those with cough and those without. Chronic cough is prevalent in patients with SDB and is associated with female sex, symptoms of nocturnal heartburn and rhinitis. Further studies are required to investigate the impact of continuous positive airway pressure therapy on cough associated with SDB to explore the mechanism of this association. PMID:20123846
