Abstract:
Introduction: The burden of Overlap Syndrome (coexistence of sleep-related breathing disorders in patients with respiratory diseases) is high in developing countries, and such a phenomenon implies higher morbidity. The study was conducted to measure the prevalence of sleep-related breathing disorders in patients with Respiratory Symptom Complex and to identify factors associated with the severity of sleep-related breathing disorders.Materials and Methods: A hospital-based cross-sectional study of 50 patients with respiratory symptom complex was conducted at BP Koirala Institute of Health Sciences. Structured proforma and Polysomnography were used for analysis.Results: There were 24 patients (48%) with COPD, 18 (36%) with Bronchial Asthma. 6 patients (12%) with Bronchiectasis and 2 patients with Interstitial Lung Disease. 60% (n=30) patients had sleep-related breathing disorder or Overlap syndrome, 14 patients (46.67%) had mild sleep-related breathing disorder while 16 (53.33%) patients had moderate to severe type. 62.5% COPD patients, 55.55% Bronchial Asthma patients, 50% of patients with Interstitial Lung Disease and 50% Post-TB Bronchiectasis patients had a sleep-related breathing disorder. There was a significant positive correlation between the presence of sleep-related breathing disorder in patients with respiratory symptom complex and high neck circumference (0.499, p-value <0.001), waist circumference (0.293, p-value = 0.039) and hip circumference (0.371, p-value = 0.008).Conclusions: Overlap Disorders comprising sleep disorders in patients with chronic respiratory diseases are high in developing countries. Routine sleep history and polysomnography in all patients with Respiratory Symptom Complex can detect sleep-related breathing disorders.

Abstract:
α1-antitrypsin deficiency (AATD) is a hereditary disorder associated with a risk of developing liver disease and pulmonary emphysema, and other chronic respiratory disorders (mainly asthma and bronchiectasis); Z variant is the commonest deficient variant of AAT. Determining AAT concentration in serum or plasma and identifying allelic variants by phenotyping or genotyping are fundamental in the diagnosis of AATD. Initial evaluation and annual follow-up measurement of lung function, including post-bronchodilator forced expiratory volume in 1 s and gas transfer inform on disease progression. Lung densitometry is the most sensitive measure of emphysema progression, but must not be use in the follow-up of patients in routine clinical practice. The exogenous administration of purified human serum-derived AAT is the only approved specific treatment for AATD in PiZZ. AAT augmentation therapy is not recommended in PiSZ, PiMZ or current smokers of any protein phenotype, or in patients with hepatic disease. Lung volume reduction and endoscopic bronchial valve placement are useful in selected patients, whereas the survival benefit of lung transplant is unclear. There are several new lines of research in AATD to improve the diagnosis and evaluation of the response to therapy and to develop genetic and regenerative therapies and other treatments.

Abstract:
Background: The neuromuscular disorders encountered in the pediatric intensive care unit (PICU) encompass a broad spectrum of pathologies. These include acute disorders (eg, Guillain-Barre syndrome), acute-on-chronic disorders (eg, myasthenia gravis), progressive disorders (eg, muscular dystrophy), and disorders that develop in the PICU (eg, critical illness myopathy/polyneuropathy). Familiarity with the presenting features of these disorders is of paramount importance in facilitating timely diagnosis. Methods: We conducted a retrospective review of the medical records of patients admitted to the PICU or Intermediate Care Program (ICP) at a single tertiary children’s hospital from 2006 to 2017 with an acute or acute-on-chronic neuromuscular disorder. We did not include patients with a known progressive neuromuscular disorder or critical illness myopathy/polyneuropathy. Results: Twenty-four patients were admitted to the PICU/ICP with acute or acute-on-chronic neuromuscular disorders. Diagnosis and indication for ICU/ICP admission were Guillain-Barre syndrome (n = 6; respiratory failure: 3, respiratory monitoring: 2, autonomic instability: 1), myasthenia gravis (n = 5; airway clearance: 3, respiratory failure: 2), acute flaccid myelitis (n = 3; respiratory failure: 2, respiratory monitoring: 1), periodic paralysis (n = 3; intravenous potassium replacement), rhabdomyolysis (n = 3; monitoring for electrolyte derangements), infant botulism (n = 2; respiratory failure), chronic demyelinating polyneuropathy (n = 1; respiratory failure), and congenital myasthenic syndrome (n = 1; apnea). No patients were admitted to the PICU/ICP with a diagnosis of tick paralysis, acute intermittent porphyria, or inflammatory myopathy. Conclusions: Although acute and acute-on-chronic neuromuscular disorders are encountered relatively rarely in the PICU, familiarity with the presenting features of these disorders is important in facilitating timely diagnosis. This, in turn, enables the institution of effective management strategies, thereby avoiding complications associated with diagnostic delays.

Abstract:
We have recently shown that background presence of chronic metabolic acid-base disorder markedly alters in vivo acute CO2 titration curve. These studies were carried out to assess the influence of chronic respiratory acid-base disorders on response to acute hypercapnia and to explore whether the chronic level of plasma pH is the factor responsible for alterations in the CO2 titration curve. We compared whole-body responses to acute hypercapnia of dogs with preexisting chronic respiratory alkalosis (n = 8) with that of normal animals (n = 4) and animals with chronic respiratory acidosis (n = 13). Chronic respiratory alkalosis and acidosis, as well as the acute CO2 titrations, were produced in unanesthetized dogs within a large environmental chamber. For comparison with our data on chronic metabolic acidosis and alkalosis, plasma bicarbonate levels, which are secondarily altered in chronic respiratory acid-base disorders, were used as an index of chronic acid-base status of the animals. Results indicate that, as with chronic metabolic acid-base disorders, a larger increment in plasma bicarbonate occurs during acute hypercapnia when steady-state plasma bicarbonate is low (respiratory alkalosis) than when it is high (respiratory acidosis). Yet, in further analogy with the metabolic studies, plasma hydrogen ion concentration is better defended at higher plasma bicarbonate levels in accordance with mathematical relationships defined by the Henderson-Hasselbalch equation. Combined results demonstrate that the influence of chronic acid-base status on whole-body response to acute hypercapnia is independent of initial plasma pH.

Abstract:
Outdoor air pollution contributed harmful impact to public health. There are several respiratory disorders related to outdoor air pollution such as acute respiratory infection, lung cancer, asthma, chronic obstructive lung disease (COPD) and lung function disorder. Respirator is a personnel protective device which has role in the primary intervention step. Currently exist many types of respirators in industrial setting that have specific function to certain hazard exposure in work process. It is difficult to choose one type of respirator that can be implemented in population setting to protect against all air pollutant content. Therefore, it is relevant choosing one respirator type which has the ability to effectively filtrate one of air pollutant content that is the particulate matter. One respirator type, N95 mask has superiority in term of cost and technical use aspects for protecting particulate matter pollutant. Respirator usage effectivity in population setting is an important subject to find out more.

Abstract:
Background: Although it is well established that chronic somatic diseases are significantly associated with a wide range of psychopathology, it remains unclear to what extent subjects with chronic somatic diseases are at increased risk of experiencing mental disorders. The present epidemiological study investigates age- and sex-adjusted 12-month prevalence rates of mental disorders in patients with cancer, and musculoskeletal, cardiovascular and respiratory tract diseases, based on comprehensive physicians’ diagnoses and compared with physically healthy probands. Methods: Prevalence rates were calculated from two large epidemiological surveys. These studies investigated inpatients and patients from the general population with cancer (n = 174) and musculoskeletal (n = 1,416), cardiovascular (n = 915) and respiratory tract diseases (n = 453) as well as healthy controls (n = 1,083). The prevalence rates were based on the Munich Composite International Diagnostic Interview, a standardized interview for the assessment of mental disorders. Results: Prevalence rates were very similar for inpatients (43.7%) and patients from the general population (42.2%). The adjusted odds ratios (OR) of patients with chronic somatic diseases were significantly elevated for mental disorders in comparison with healthy probands (OR: 2.2). Mood, anxiety and somatoform disorders were most frequent. The prevalence rates did not differ significantly between the somatic index diseases. The number of somatic diseases per patient had a higher association with mental disorders. Conclusions: There is a strong relationship between chronic somatic diseases and mental disorders. A future task is to improve the care of mental disorders in patients with chronic physical illness, specifically with multimorbid conditions.

Abstract:
Background: Chronic cough is a common health problem with variable success rates to standardized treatment. Psychologic symptoms of depression, anxiety, and stress have been reported in association with chronic cough. The purpose of this study was to examine changes in the psychologic symptoms of depression, anxiety, and stress in adults with chronic cough 3 months after management using the ACCP cough treatment guidelines. Methods: This study used a descriptive longitudinal observation design. The major tenets associated with the Theory of Unpleasant Symptoms were examined. Intervention fidelity to the study components was measured. Results: A sample of 80 consecutive patients with chronic cough of greater than 8 weeks duration was recruited from one cough specialty clinic. Mean age of subjects was 58.54 years; 68.7% were female; 98.7% were white, and 97.5% were non-smokers. Mean cough duration was 85.99 months and mean cough severity was 6.11 (possible 0 –10; higher scores equal greater cough severity). Cough severity improved post treatment (n=65, M=2.32, (SE =.291), t (64) =7.98, p=.000); cough-specific quality-of-life also improved (n=65, M=9.17, (SE=1.30), t (64) =7.02, p=.000). Physiologic (urge-to-cough r=.360, ability to speak r=.469) and psychologic factors (depression r=.512, anxiety r=.507, stress r=.484) were significantly related to cough-specific quality-of-life and to cough severity (urge-to-cough r=.643, ability to speak r=.674 and depression r=.356, anxiety r=.419, stress r=.323) (all r, p=.01); social support and number of diagnoses were not related to either variable. Those experiencing greater financial strain had worse cough severity. Women, those experiencing financial strain, and those taking self-prescribed therapy had worse cough-specific quality-of-life. Intervention fidelity to the study plan was rated as high according to observation, participant receipt, and patient/physician concordance. Qualitative review identified potential areas of variability with intervention fidelity. Conclusions: By measuring the factors related to the major tenets of the Theory of Unpleasant Symptoms, this theory has helped to explain why those with chronic cough may have symptoms of depression, anxiety, and stress and why these symptoms improve as cough severity and cough-specific quality-of-life improve. Moreover, by measuring intervention fidelity, it may be possible to determine why cough guidelines may not be yielding consistently favorable results.

Abstract:
Aim. To assess associations between occupational air pollution and respiratory health, especially in miners. Background. Indications of associations between occupational exposure or social economic status and respiratory health have been found in several population-based studies. However, there have been few longitudinal studies of the putative correlations, the effects of environmental and genetic factors have seldom been simultaneously studied, and studies of miners have generated conflicting results. Material and methods. Population-based Obstructive Lung Disease in Northern Sweden (OLIN) cohorts surveyed in 1986, 1992 and 1996, and two industry-based materials, were used in cross-sectional and longitudinal studies. Inflammatory markers were compared in sputa from miners after a vacation of at least four weeks, after repeated occupational exposures for at least three months, and controls. The mortality from silicosis was studied in 7729 miners with at least 1 year of exposure. Multivariate analyses were used to adjust for confounders. Results. Up to about 30-40% (etiologic fraction) of incident symptoms in persons both with and without a family history of asthma (FHA) could be explained by exposure to occupational air pollution. Low socio-economic status (SES) was associated with impaired respiratory health. Population attributable risks for most examined disorders were about 10%. Current and ex-miners had increased prevalence of recurrent wheeze, longstanding cough, physician-diagnosed chronic bronchitis, and a trend for increased sputum production. For physician-diagnosed chronic bronchitis a multiplicative interaction was found between exposure and smoking habits. Ex-miners that had been exposed for on average 13 years and whose exposure had ceased 16 years before the study had an increased prevalence of physician-diagnosed chronic bronchitis and chronic productive cough and a trend to increased use of asthma medicines. Miners exposed underground for 18 years, on average, to diesel exhaust (with 0.28 mg/m3 nitrogen dioxide and 27 μg/m3 elemental carbon on average, EC) and particles (3.2 mg/m3 inhalable dust on average) had signs of higher inflammatory activity in their airways, i.e. significantly higher frequencies of macrophages, neutrophils, and total cells compared with referents. The activity in miners was similar after a vacation of at least four weeks and after repeated exposures for three months. There were 58 deaths from silicosis (underlying and contributing cause of death) and a clear dose-response relationship. The data indicated an increased risk of severe silicosis after long-term exposure to 0.1 mg/m3 respirable quartz, the current maximum allowable concentration (MAC) in Sweden and many other countries. Conclusion. Occupational exposure to dust, gases, and fumes impaired respiratory health, accounting for up to 30-40% of some respiratory symptoms in the general population. Low socio-economic status was associated with impaired respiratory health. The complex profiles of dust and diesel exhaust substances found in mines may cause inflammatory reactions in their lungs and persistent respiratory symptoms in occupationally exposed miners. Long-term exposure to quartz at the present MAC level may cause severe silicosis.

"Systems approach to managing chronic occupational respiratory disorders| Shared path for improving the pneumoconiosis screening program for South African ex-miners in Botswana."

Abstract:

Pneumoconiosis is a chronic and slowly progressive parenchymal lung disease. Estimates suggest that about 68,000 ex-miners in Botswana will develop or have already developed pneumoconiosis. However, most of these cases do not know they have the disease because of the poor quality of care in primary healthcare settings and weak implementation of the Occupational Diseases in the Mines and Works (ODMW) Act.

This dissertation was a health service research framed from the systems approach using the chronic care model as a theoretical tool. The study employed a concurrent, convergent parallel mixed method research which combined quantitative and qualitative methods of inquiry. The quantitative arm of the study evaluated whether the Botswana primary care settings meet ‘reasonably good standards’ of the pneumoconiosis quality of care measured on the chronic care model. The chronic care model measures quality of care on a 0 to 11 scale, where “0” denotes lack of quality care and “11” stands for optimal quality of care. Reasonably good quality of care comprises scores between 6 and 8 on the scale. The qualitative arm of the study assessed the implementation of the ODMW Act in the Botswana primary healthcare settings. The study mixed quantitative and qualitative results at the interpretation stage to determine the extent to which quality of care for pneumoconiosis and the ODMW Act implementation promote equitable access to pneumoconiosis services among ex-miners in Botswana.

Abstract:
L’objectif de cette thèse est de conceptualiser, à partir de l’exploitation des données de remboursement de soins de l’Assurance Maladie, les différentes trajectoires de recours aux soins relatives à la prise en charge d’une pathologie chronique (asthme), et d’étudier les déterminants de ces trajectoires du point de vue du profil et du comportement subséquent du prescripteur de soins. L’étude de la relation entre le comportement prescriptif et la trajectoire de soins est appréhendée par des techniques de modélisation et d’analyses multivariées. L’objectif sous-jacent est d’évaluer, d’un point de vue médico-économique, l’impact de la typologie des prescripteurs (caractéristiques des offreurs de soins) sur les différentes trajectoires de soins suivies par les patients atteints de la pathologie définie supra. Les caractéristiques susceptibles d’identifier une typologie de prescripteur correspondent aux variables influant sur le comportement prescriptif, au sens large, du médecin (âge, sexe, durée d’exercice, type d’exercice, etc.). La question principale de la thèse est celle de l’effet régulateur de l’incitation économique, instaurée par le parcours de soins coordonnés (réforme de l’Assurance Maladie, août 2004), sur les trajectoires de soins, réellement observées, de patients atteints de pathologies chroniques. Les corollaires sont : Le déremboursement des actes hors parcours de soins coordonnés peut-il avoir un impact significatif sur la trajectoire empirique de prise en charge du patient ? Le profil du prescripteur d’actes médicaux a-t-il, toutes choses égales par ailleurs, un effet sur le respect ou non de la trajectoire de soins référentielle admise par le parcours de soins coordonnés ? Quels sont les déterminants principaux du non respect de cette trajectoire référentielle, du point de vue de l’analyse des caractéristiques des couples « médecin – patient» ?
The objective of this thesis is to conceptualize, starting from the exploitation of the refunding data of cares from the Sickness insurance, the various trajectories of cares recourses introduced by chronic diseases as asthma, and to study their determinants by analysing the profile and the subsequent behavior of the general practitioner. The study of the relation between the prescriptive behavior and the trajectory of cares is carried out by different multivariate analyses. The other objective is to evaluate, from a pharmacoeconomic point of view, the impact of the general practitioner characteristics on the various trajectories of cares followed by the patients with chronic diseases. The characteristics likely to identify a typology of practitioners correspond to the variables influencing the prescriptive behavior (age, sex, duration of exercise, type of exercise, etc). The principal question of the thesis is that of the regulating effect of the economic incentive, rested on the coordinated care pathway (reform of the Sickness insurance, August 2004), on the trajectories of cares, really observed by the chronic patients. The corollaries are: Does the no-reimbursement of some medical acts, not considered in the coordinated care pathway, have a significant impact on the empirical recourse of the patient? Does the profile of the general practitioner have an effect on the respect or not of the allowed trajectory of cares classified by the French reform? Which are the principal determinants of disregarding this referential trajectory, by notably analysing the “practitioner - patient” characteristics?

Objective Evaluate, social competence and behavior disorders in children with moderate to severe asthma according to parental perception. Casuistics: Sixty-two patients were studied, 36 male and 26 female, ages ranging from 7 to 16 years (MA: 10.94; SD: 2.28), with clinical diagnosis of moderate to severe asthma, without comorbidity, seen at the Pediatric Pneumology Service and the Allergy and Immunology Service at a University Hospital, from March to September, 2000. A control group was simultaneously studied and included 62 patients, 37 male and 25 female, ages ranging from 7 to 16 years (MA: 10.26; SD: 2.37), seen at the Orthopedics and Ophthalmology Outpatient Wards at the same hospital, without symptoms of asthma, respiratory allergy and no chronic diseases. Material and method An Identification Form, a Clinical Data Form and the CBCL (Child Behavior Checklist), a tool to evaluate social competence and behavior disorders, were used. Results Results were evaluated by the proportional tests, Student s t test and ANADEP and ANADEPMU and a significance level of 0.05 was chosen. Patients were classified according to the clinical manifestations of asthma: 42 had moderate asthma and 20 had severe asthma, most of them (93.55%) had been diagnosed since 3 years of age. There was no significant difference in age and gender between the group with asthma and the control group. There was a marked association between overall social competence and asthma (with p=0.000) and between social competence associated to activities (with p=0.001) and school (with p=0.01). There was no difference between children with asthma and the control group for social markers (with p=0.23). There was no correlation between gender and age when evaluating social competence, or overall social competence specific parameters: activities, school and social activities. The evaluation of social competence and type of asthma did not show a correlation. There was a strong association between the presence of behavior disorders and asthma (p=0.005), specially internalizing disorders (p=0.001). There was no association between the externalizing disorders and the disease. Behavior disorders were not associated to gender, age and type of asthma. Conclusions Children with asthma showed alterations in overall social competence and social competence related to activities and school, when compared to the control group. They also showed overall and internalizing disorders, which may be harmful to their development, their quality of life, compliance with the treatment and adequate management of the disease. The integration of biological, psychological and social factors is essential to establish adequate programs for the treatment of children with asthma and their families.

Um grupo de controle foi estudado no mesmo período, composto de 62 pacientes, 37 do sexo masculino e 25 do sexo feminino, com idade entre 7 e 16 anos (im: 10,26; dp: 2,37), atendidos nos ambulatório de ortopedia e oftalmologia do mesmo hospital, sem qualquer sintomatologia de asma, de alergia respiratória e sem qualquer doença crônica. Material e método - foram utilizados na obtenção dos dados uma ficha de identificação, uma ficha de dados clínicos e um instrumento que avalia competência social e transtornos comportamentais - child behavior checklist (cbcl). Resultados - os resultados foram analisados com testes proporção x (ao quadrado), teste t de student, anadep e anadepmu, adotando-se nível de significância de 0,05. Os pacientes foram classificadossegundo manifestações clínicas da asma: 42 com asma moderada e 20 com asma grave, sendo que 93,55% receberam o diagnóstico da doença antes dos 3 anos de idade. Não houve diferença significante em termos de idade e sexo entre os grupos com asma e controle. Houve associação entre competência social e global e asma (p=0,000) e entre competência social associada a atividades (p=0,001) e escola (p=0,01). Não houve diferença entre crianças com asma e o grupo controle em relação ao aspecto social (p=0,23). Não houve relação entre sexo e idade na análise da competência social, nem quanto à competência social global nem quanto aos aspectos específicos: atividades, escola e social. A análise entre competência social e tipo de asma também não mostrou associação. Houve associação entre presença de transtornos comportamentais e asma (p=0,005), principalmente os transtornos internalizantes (p=0,001). Não houve associação dos externalizantes com a doença. Os transtornos comportamentais não se mostraram associados ao sexo, idade da amostra e tipo de asma. Conclusões - as crianças com asma apresentaram alterações na competência social e global e competência social relacionada a atividades e escola, quando comparadas ao grupo controle. Apresentaram ainda transtornos globais e internalizantes, que podem prejudicar o seu desenvolvimento, sua qualidade de vida, a adesão ao tratamento e o manejo adequado da doença. A integração dos aspectos biológicos, psicológicos e sociais é imprescindível para o delineamento de programas adequados de atendimento à criança portadora de asma e a seus familiares.

Abstract:
This chapter describes the clinical presentation of commonly-encountered occupational and environmental respiratory disorders, including principles regarding disease recognition and prevention. Where appropriate, clinical cases are included to illustrate specific diseases. The chapter begins with a general introduction to the evaluation of individuals and populations, including important considerations from the history and physical examination as well as common findings on typical diagnostic tests such as chest X-rays and other imaging studies, and pulmonary function testing. Specific disease topics covered include (a) disorders due to irritant exposures (high-, moderate-, and low-solubility irritants); (b) disorders due to nonirritant exposures (carbon monoxide and indoor and ambient air pollution); (c) occupational airways diseases (work-related asthma and occupational chronic obstructive pulmonary disease); (d) hypersensitivity pneumonitis, byssinosis, and other diseases due to organic dust exposure; and (e) pneumoconiosis (including asbestosis, silicosis, and coal workers’ pneuconiosis). Childhood asthma is discussed as a risk factor for occupationally-related lung disease.

Abstract:
A range of fungal disease syndromes affect patients with chronic respiratory diseases and cystic fibrosis (CF). Invasive aspergillosis is increasingly recognized in seriously ill patients with chronic obstructive pulmonary disease, especially after high-dose steroids. Chronic pulmonary aspergillosis affects patients with pre-existing cavities or bullae, such as those with previous tuberculosis or atypical mycobacterial disease, bullous emphysema, sarcoidosis, pneumothorax, or treated lung cancer. In addition, fungi have become one of the most important trigger agents for asthma, and allergic bronchopulmonary aspergillosis may complicate up to 3.5% of cases of asthma and up to 15% of cases of CF, starting in childhood. CF patients are commonly colonized with fungal organisms, although the impact of such colonization on outcome is not clear. Aspergillus is the most common mould isolated from CF patients. Distinguishing between colonization and infection remains challenging. Candida is thought to be of no clinical significance; however, it has been associated with decline in lung function.

Abstract:
Respiratory medicine is a diverse specialty involving common chronic diseases, rarer conditions, pulmonary involvement in systemic disorders, lung infections, tumours, and adverse drug effects. It is also an important component of general internal medicine. Respiratory medicine has been prominent in producing clinical guidelines, many of which are now evidence-based, and hence a good source of information and reference. Some of the commonest medical conditions, including asthma and lung cancer, are rooted in respiratory medicine. Although declining, lag effects mean these conditions are increasingly prevalent and continue to be important, particularly in the developing world. Sleep medicine is now also beginning to receive attention, and respiratory infections remain common. Respiratory research is broad-based, but the level of government and major charity funding is low. This chapter summarizes important recent clinical papers under the subheadings of asthma, chronic obstructive pulmonary disease, infection, lung cancer, and smoking, with contributions from pulmonary vascular disease and sleep.

Abstract:
Sleep disorders and pulmonary diseases are closely associated, a fact clearly underestimated in routine patient care, despite evidence that these disorders interact to impact on quality of life as well as on morbidity and mortality. The prevalence of chronic insomnia, sleep-related breathing disorders, and restless leg syndrome is high in patients with chronic pulmonary disorders such as asthma, chronic obstructive pulmonary disease, cystic fibrosis, interstitial lung disease, chest wall and neuromuscular disorders, and chronic respiratory failure. This association may be fortuitous and reflect the impact of a chronic condition on sleep quality, or it may be due to specific sleep-related phenomena adversely affecting an underlying pulmonary disorder. Furthermore, obstructive sleep apnea has been implicated as a risk factor for pulmonary hypertension and pulmonary embolism. This chapter outlines the implications for both pulmonary and sleep specialists, in terms of clinical management and treatment strategies.

Abstract:
The prevention of disease at a population health level rather than an individual health level is aimed at reducing causes of ‘preventable’ death and, under the auspices of public health and epidemiology, is an integral part of primary, secondary, and tertiary care. Classification of death is usually according to the type of primary disease or injury. However, there are a number of recognized risk factors for death, and modifications in behaviour or risk factors can substantially reduce preventable causes of death and the associated healthcare and economic burden of chronic disease management. According to the WHO, hundreds of millions of people from infancy to old age suffer from preventable chronic respiratory diseases, there are over four million deaths annually from preventable respiratory diseases, and common respiratory disorders (e.g. lower respiratory tract infections, chronic obstructive pulmonary disease, lung cancer, and tuberculosis) account for approximately 20% of all deaths worldwide. This chapter discusses the prevention of respiratory disease, covering diseases associated with smoking (one of the biggest risk factors associated with preventable deaths), air pollution, and other lifestyle factors associated with respiratory disease; changes in legislation concerning smoking and work-related respiratory disease; and, finally, the prevention of respiratory diseases through the use of immunization and screening tools.

Abstract:
In clinical settings, doctors classify pulmonary disorders into two main categories, obstructive lung disease and restrictive lung disease. The former is characterized by the airway obstruction which is associated with several disorders like chronic bronchitis, asthma, bronchiectasis, and emphysema [1]. The latter is caused by different conditions where one of the triggers is tied to the spine deformity. In general, a pulmonary function test (PFT) [2] is used to evaluate and diagnose lung function, and physicians depend on the test results to identify the disease patterns of the patients (obstructive or restrictive lung disease). In the PFT, some parameters including total lung capacity (TLC), vital capacity (VC), and residual volume (RV) can infer the lung volume and lung capacity. Other parameters, such as forced vital capacity (FVC) and forced expiratory volume in the first second (FEV1), are often employed to assess the pulmonary mechanics. Scoliosis is an abnormal lateral curvature of the spine which involves not only the curvature from side to side but also an axial rotation of the vertebrae. Restrictive lung disease often happens in scoliosis patients, especially with severe spine deformity. Spine deformity if left untreated may lead to progression of the spinal curve, respiratory complications, and the reduction of life expectancy due to the decrease in thoracic volume for lung expansion. However, the relationship between thoracic volume and pulmonary function is not broadly discussed, and anatomic abnormalities in spine deformity (ex: scoliosis, kyphosis, and osteoporosis) can affect thoracic volume. Adequate thoracic volume is needed to promote pulmonary function. Previous literature has shown that the deformity of the thoracic rib cage will have detrimental effects on the respiratory function in adolescent idiopathic scoliosis patients [3–4]. In this paper, we aim to correlate thoracic volume and the parameters in PFTs in adult scoliosis patients 25–35 years after receiving treatments during their adolescence, either with physical bracing or spinal fusion surgery.

Abstract:
A relationship between the quality of environment and incidence of human health has been recognized in recent years. While the diseases such as carcinogenesis, respiratory diseases, skin disorders are often correlated with exposure to environmental toxins, the possibility of a link between blood coagulation and chemical contaminants in food, water and air has rarely been suspected. Wide usage of DDT in public health and plant protection programmes have led to a considerably higher levels of the pesticide in the blood and body fat of Indian population. Therefore, in order to explore the possibilities of an alteration in blood coagulation and fibrinolysis in response to pesticide insult, a study was undertaken in experimental animals.Adult male albino rats were administered technical grade DDT, 100 mg per kg body weight i.p. for 3 consecutive days for acute exposure study and fed food containing the pesticide at a concentration of 100 mg per kg diet for a duration of 90 days for chronic exposure. Coagulation and fibrinolytic status was assessed at the end of exposure period. Acute exposure to DDT significantly increased platelet count but decreased wall adherence of blood while chronic exposure to DDT elevated platelet counts by 21% and increased wall adherence of blood by 28%. Plasma clotting times were found to be shortened considerably both in acute and chronically exposed animals. DDT seemed to activate both extrinsic and intrinsic pathway of coagulation as evident by marked acceleration in prothrombin time and partial thromboplastin time. Plasma fibrinogen concentrations were found to be higher by 31.6% in rats given acute treatment but 40% lower in chronically exposed animals. A marked increase in fibrinolytic activity was observed in both acutely and chronically exposed animals. Thus, administration of chlorinated pesticides like DDT seemed to have a prothrombotic effect in experimental animals.

Abstract:
Respiratory diseases such as asthma or chronic obstructive pulmonary disorder (COPD) affect millions of people around the world. The most common treatment approach is to take an inhaled corticosteroid as needed with a dry-powder inhaler or a metered-dose inhaler. Unfortunately, rates of inhaler mishandling and misuse are staggeringly high and as a result, the majority of those suffering from asthma and COPD are not receiving proper treatment. There are a myriad of ways inhalers are mishandled and misused, but one significant challenge results from the timing miscoordination of the medicine dispersion and inhalation breath. To address this, the current study successfully demonstrates the feasibility of automating the timing of the medicine dispersion by the addition of a Shape Memory Alloy (SMA) actuator and a differential pressure sensor into the casing of a traditional metered-dose inhaler. To meet actuation requirements and reliably depress the inhaler cartridge, the SMA wire was routed around a set of miniature bearings within the casing of the inhaler. By demonstrating that a metered-dose inhaler may be actuated by SMA without a significant increase of its weight or size, this study provides a practical technological approach to reducing the improper treatment of asthma and COPD due to inhaler misuse.

Abstract:
Cases of death during heat waves are most commonly due to respiratory and cardiovascular diseases, with the main contribution from the negative effect of heat on the cardiovascular system. In an attempt to control the body temperature, the body’s natural instinct is to circulate large quantities of blood to the skin. However while trying to protect itself from overheating, the body actually harms itself by inducing extra strain on the heart. This excess strain has the potential to trigger a cardiac event in those with chronic health problems, such as the elderly. Those in the U.S.A. between the ages of 65 and 74 are at a higher risk of mortality during heat waves when they are single, have a history of chronic pulmonary disease, or suffer from a psychiatric disorder. In the older group, 75+, single people are again more vulnerable as well as women. The relationship of mortality and temperature creates a J-shaped function, showing a steeper slope at higher temperatures. Records show that more casualties have resulted from heat waves than hurricanes, floods, and tornadoes together. The significance of this is that the U.S. suffers the highest damage total from natural catastrophes annually. Studies held from 1989–2000 in 50 U.S. cities recorded 1.6% more deaths during cold temperature events, as opposed to a staggering 5.7% increase during heat waves. People are at risk when living in large metropolitan areas, especially those mentioned above, due to the heat island effect. Urban areas suffer heat increases from the combination of global warming effects as well as localized heat island properties. It is flawed to claim that the contribution of anthropogenic heat generation to the heat island effect is small. Analyzing the trend of extreme heat events (EHEs) between 1956 and 2005 showed an increase on average of 0.20 days/year, on a 95% confidence interval with uncertainty of ±0.6. This trend follows the recorded data for 2005 with 10 more heat events per city than in 1956. Compact cities experience an average of 5.6 days of extreme heat conditions annually, compared to that of 14.8 for sprawling cities. The regional climate, city populace, or pace of population growth however does not affect this effect. Statistics from the U.S. Census state that the U.S. population without air conditioning saw a drop of 32% from 1978 to 2005, resting at 15%. Despite the increase in air conditioning use, the positive affects of it may have run their course as a critical point may have been reached. A study done by Kalkstein through 2007 proved that the shielding effects of air conditioning reached their terminal effect in the mid-1990s. Heat-related illnesses and mortality rates have slightly decreased since 1980, regardless of the increase in temperatures. This may be in part to the increase in availability of air conditioning, and other protective measures, to the public. Protective factors have mitigated the danger of heat on those vulnerable to it, however projecting forward the heat increment related to sprawl may exceed physiologic adaptation thresholds.
