Resumen

The objective of the study was to assess whether the incidences of Crohn’s disease and ulcerative colitis are increased in patients with asthma and chronic obstructive pulmonary disease (COPD) compared to the general population.A population-based retrospective cohort study was conducted using the administrative health databases of Québec, Canada. Incidences of Crohn’s disease and ulcerative colitis among patients with asthma and COPD were assessed for the 2001–2006 period.In total, 136 178 subjects with asthma and 143 904 subjects with COPD were identified. The average incidence of Crohn’s disease and ulcerative colitis was 23.1 and 8.8 per 100 000 person-years among asthmatic patients; in the COPD cohort there were 26.2 Crohn’s disease cases and 17 ulcerative colitis cases per 100 000 person-years. The incidence of Crohn’s disease in asthma and COPD patients was 27% and 55% higher than in the general population of Québec; the incidence of ulcerative colitis was 30% higher among COPD patients compared to the general population.Incidence of inflammatory bowel disease was significantly increased in asthma and COPD patients compared to the general population of Québec. Incidence rates were particularly high in patients with COPD. Awareness of an association between airway diseases and inflammatory bowel disease in older age groups may play an important role in earlier detection of bowel disease and in the therapeutic management of such patients.

Resumen

We aimed to test the hypothesis that adherence to a healthful plant-based diet (hPDI) is associated with a subsequent decrease in the incidence of asthma symptoms, with an opposite association with adherence to an unhealthful plant-based diet (uPDI). In addition, we evaluated a potential mediating role of body mass index (BMI) and the modifying effect of smoking. Among 5700 elderly women from the French Asthma-E3N study with dietary data in 1993 and 2005, we assessed the incidence of asthma symptoms in 2018 among women with no asthma symptoms in 2011. BMI was evaluated in 2008. Mediation analyses in the counterfactual framework were used to disentangle total, direct, and indirect effects mediated by BMI. We found that both healthful and unhealthful plant-based diets were associated with a lower incidence of asthma symptoms over time, mediated by BMI (OR (95%CI) for the indirect effect: 0.94 (0.89–1.00) for hPDI and 0.92 (0.70–1.00) for uPDI)). Associations with both healthful and unhealthful PDIs were mediated by changes in BMI by 33% and 89%, respectively. Plant-based diets (healthful and unhealthful) were associated with subsequently reduced incidences of asthma symptoms over time, partly or almost totally mediated by BMI according to their nutritional quality.

Resumen

Asthma represents the most common chronic disease in childhood. Children with asthma are at increased risk for developing long-term irreversible airway obstruction in adult life, the fourth leading cause of death in USA. Our aims were to: (1) Determine whether reduced IFNgamma production and plasma soluble CD14 (sCD14) levels in early life are significant risk factors for the development of wheezing in the first year of life; (2) Estimate rates of persistence and remission of childhood wheezing after puberty; (3) Study risk factors affecting persistence of childhood wheezing after puberty. We used data from the two large ongoing birth cohorts of the Tucson Infant Immune Study (IIS) and the Tucson Children's Respiratory Study (CRS). Among 238 children from IIS, we found the odds of developing recurrent wheezing in the first year of life to be 4.5 times higher for children in the lowest quartile of IFNgamma production at 3 months (p = .0005) and 3.2 times higher for children in the lowest quartile of sCD14 levels at birth (p = .004) as compared with children in the other 3 combined quartiles of IFNgamma and sCD14, respectively. We studied persistence and remission of wheezing after puberty among 732 children from the CRS cohort. We found that 29% of children with infrequent wheezing during childhood experienced persistent wheezing after contrast, the proportion of persistent wheezing was much higher (60%) among children meeting the for asthma during childhood. Frequency of wheezing during childhood, obesity, an early onset of puberty, bronchial hyperresponsiveness, and skin test sensitization were significant predictors of persistent asthma after puberty. By looking at genetic factors, we also found that the homozygous status for Gly in codon 16 of the beta2 Adrenoceptor doubled the risk for persistent wheezing after puberty among boys (RR 2.01, p = .0008) but not girls. Our findings from two population-based longitudinal cohorts provide the first evidence that altered immunological markers precede the onset of wheezing early in life, challenge the commonly held view that most asthma cases remit during adolescence, and provide a profile of risk.

Resumen

IntroductionLes raisons de l’excès de risque d’asthme chez la femme ne sont pas établies. La réversion du sexe ratio autour de la puberté a fait évoquer le rôle des hormones sexuelles féminines dans l’asthme. Cependant l’histoire naturelle de l’asthme après 50 ans a été très peu étudiée. L’objectif général de cette thèse était d’apporter des nouveaux éléments de connaissance sur l’histoire naturelle de l’asthme de la femme. Les objectifs spécifiques étaient l’étude de l’incidence de l’asthme allergique et non-allergique de la femme et de son évolution avec le vieillissement (différences par rapport aux hommes après 50 ans, et association avec la ménopause) et l’étude de certains facteurs de risque associés à l’asthme de la femme.Matériels et méthodesL’incidence et l’évolution de l’asthme ont été étudiées chez 2 125 hommes et 2 298 femmes, initialement âgés de 20 à 44 ans et suivis pendant 20 ans dans la cohorte européenne sur la santé respiratoire « ECRHS ». Les associations entre la ménopause et l’asthme de la femme ont été étudiées dans un échantillon de 67 872 femmes, initialement âgées de 41 à 68 ans et suivies pendant 12 ans au sein de la cohorte E3N. Les données sur les expositions environnementales de l’Etude des facteurs Génétiques et Environnementaux de l’Asthme (EGEA) ont été utilisées pour étudier l’association entre l’usage domestique d’eau de Javel et l’asthme auprès de 607 femmes âgées de 44 ans en moyenne. L’asthme allergique est défini par la présence de tests cutanés positifs.RésultatsDans la cohorte ECRHS, les femmes étaient plus à risque que les hommes de développer de l’asthme non-allergique (Odds-Ratio (OR) ; Intervalle de confiance à IC95% : 4,0 [2,5-6,5]). Cette différence était moins marquée pour l’asthme allergique (OR 1,7 [1,0-2,7]), et on n’observait pas de différence dans la progression de l’asthme.L’analyse de la cohorte E3N ne montre pas de différence dans l’incidence de l’asthme entre les femmes pré-ménopausées et post-ménopausées de même âge, chez les femmes de corpulence normale (Hazard Ratio(HR) :1,1 [0,8-1,3]). Cependant, chez les femmes obèses, l’incidence de l’asthme augmentait lors de la transition vers la ménopause (aHR :1.9[1.0-3.7]) et en post-ménopause (HR :2,9 [1,1-4,1]). La ménopause chirurgicale était également associée à un plus grand risque d’asthme.Dans la cohorte EGEA, seuls 2% d’hommes contre 37% des femmes utilisaient hebdomadairement l’eau de Javel pour faire le ménage. Chez les femmes, l’usage fréquent d’eau de Javel était associé à un plus grand risque d’asthme non-allergique (OR :1,7 [IC :1,0-3,0]), mais il n’y a pas d’association avec l’asthme allergique. Chez les femmes asthmatiques, l’usage d’eau de javel était associé à une neutrophilie plus élevée.ConclusionA l’issue de ce travail, nous avons montré que le risque accru d’asthme chez la femme persistait au-delà de la période reproductive, et que la chute des hormones sexuelles féminines à la ménopause n’était pas indépendamment associée à l’incidence de l’asthme. D’autres facteurs, dont l’interaction entre les facteurs métaboliques et hormonaux, et les expositions genre-dépendantes pourraient expliquer l’excès de risque d’asthme non-allergique chez la femme
IntroductionThe reason for the higher asthma incidence in women during the reproductive years is still unknown. The gender switch in asthma incidence around puberty has been put forward to suggest a role of female sex hormones in asthma. However, there are limited findings in the natural history of asthma after age of 50 and whether the transition through menopause is associated with change in asthma incidence is unknown.The objective of this thesis was to investigate the natural history of allergic and non-allergic asthma in women in term of incidence, evolution with aging (menopause) and risk factors of asthma in women with a focus on the gender differences.Materials and methodsThe gender differences in allergic and non-allergic asthma was assess in 2.125 men and 2.298 women free of asthma at baseline (aged 20-44) followed for 20 years as a part of the European Community Respiratory Health Survey (ECRHS). The association between asthma incidence and menopausal status was assessed in 67,872 women free of asthma at baseline (aged 41-68 years) and regularly followed-up as a part of the French E3N cohort. Association between the domestic use of cleaning bleach and allergic and non-allergic asthma have been assess in 607 women (mean age 44 years) participating in the first follow-up of the Epidemiological Study on the Genetics and Environment of Asthma (EGEA). Allergy was define by a positive skin prick test.ResultsWith data from ECRHS we showed that the incidence of non-allergic asthma was higher in women as compared to men (Odds Ratio (OR): 4.0 [95% Confident Interval (CI95%): 2.5-6.5]. The female predominance was less marked for allergic asthma (OR :1.7 [IC :1.0-2.7]). However, in asthmatics there was no gender differences in the progression of asthma. With data from E3N we showed that among normal-weight women, there was no difference in asthma incidence between premenopausal and naturally postmenopausal women of the same age (Hazard Ratio(HR) :1,1 [0,8-1,3]). However, in obese women, the transition through menopause (HR: 1.9[1.0-3.7]) and the later period after menopause (HR:2.1 [1.1-4.1]) were associated with a higher asthma incidence. Surgically post-menopausal women were also at increased risk of developing asthma (HR:1.33[95%CI 1.01-1.75]).In EGEA, only 2% of men and 37% of women reported using bleach weekly for home cleaning. Women using bleach were at increased risk for non-allergic asthma (OR 3.3; 95%CI 1.5-7.1), and more particularly for non-allergic adult-onset asthma (OR 4.9; 95%CI 2.0-11.6). No association was observed for allergic asthma. Among women with asthma, frequent use of bleach was significantly associated with higher blood neutrophil cell counts.ConclusionGender differences in asthma incidence still persist in older adults however, changes in female sex hormones level occurring around natural menopause was not independently associated with change in asthma incidence in women. Our findings do not support the hypothesis that female sex hormones are independently associated with asthma incidence. The interaction between metabolic and hormonal factors and the gender difference in environment factor such as bleach use might explain the gender switch in asthma incidence around puberty and the female predominance in asthma more particularly for non-allergic asthma in adulthood

Resumen

Contexte - Concernant l'histoire naturelle de l'asthme professionnel (AP), les évidences s'accumulent sur le fait que le processus inflammatoire menant à l'asthme clinique se développe tôt dans le cursus des travailleurs. L'étude ABCD - Asthme en Boulangerie et Coiffure Débutant - poursuit deux objectifs : 1) décrire l'évolution temporelle de l'incidence de l'AP au cours des premières années d'exposition de boulangers/pâtissiers (BP) et coiffeurs - secteurs reconnus à risque d'AP - et 2) identifier les facteurs de risque personnels, professionnels et nutritionnels influençant cette incidence. Méthode - L'étude ABCD repose sur deux facettes intriquées : (i) une cohorte longitudinale rétrospective d'anciens apprentis d'ancienneté croissante permettant l'estimation de l'incidence précoce de l'AP, et (ii) une étude de type cas-témoin nichée dans la cohorte explorant certains facteurs de risque de l'AP. Résultats - 866 sujets participèrent à l'étude qui mit en évidence une incidence cumulée de l'AP élevée lors des 4 premières années d'exposition chez les BP, et dans un moindre degré chez les coiffeurs. Le risque d'AP dépend du statut atopique chez les BP ; il est positivement associé, chez les coiffeurs, à l'intensité de l'exposition et, dans une moindre mesure, à l'indice de masse corporelle et à certains facteurs nutritionnels. Conclusions - Cette étude a permis de produire des données originales sur l'incidence précoce de l'asthme professionnel. Ces données constituent un support pour le développement de campagnes de prévention, notamment pour la détection précoce de la maladie dès les premières années d'exposition
Context - Regarding the natural history of occupational asthma (OA), there is increasing evidence that the inflammatory process leading to clinical asthma appears early after inception of exposure. The ABCD study (French acronym for early asthma in bakery and hairdressing) aims to answer two objectives: 1) describe the temporal evolution of the OA incidence in the early years of exposure of bakers/pastry-makers (BP) and hairdressers - occupations known at risk of OA - and 2) identify personal, occupational and nutritional risk factors. Method - The ABCD study has two intertwined facets: (i) a retrospective longitudinal cohort of past apprentices of increasing seniority allowing to estimate the early incidence of OA, and (ii) a nested case-control study allowing to explore some risk factors of OA. Results - 866 subjects participated to the study. The ABCD study shows a high cumulative incidence of OA during the first 4 years of exposure among BP, and in a lesser extent, among hairdressers. While the OA risk depends on atopic status for BP, it is positively associated, for hairdressers, with exposure intensity and, to a lesser extent, to body mass index and with a variety of nutritioal factors. Conclusions - This study produced original data on early incidence of OA. These data may provide support for the development of preventive action, in particular for the detection of OA in the early years of exposure

Resumen

Background In the past half-century, the prevalence of asthma among children and adolescents has risen and asthma has become an important public health challenge in Sweden as well as in many other countries, necessitating further studies on this complex disease and its risk factor pattern. The studies included in this thesis aimed to investigate the clinical expression of childhood asthma over time, to describe the determinants of new-onset and remission of asthma, and to evaluate possible environmental risk factors in northern Sweden. Methods As the result of a repeated questionnaire survey among primary school children aged 7-8 years in three municipalities in the north of Sweden, two pediatric cohorts were formed, one in 1996 (n=3430) and one in 2006 (n=2585). The cohort created in 1996 was followed annually until the age of 19 years. Skin prick testing was performed on children in both cohorts. Lung function and bronchial hyperreactivity testing were carried out in children with asthma in the first cohort. The study participation and retention rates were very high in both cohorts. Among children in the second cohort living in Luleå, the home addresses were assigned to coordinates in a geographical information system (GIS) to evaluate the impact on respiratory health of living near roads with much traffic, which was measured as the number of vehicles daily. We used a validated reported diagnosis of asthma and International Study of Asthma and Allergies in Childhood (ISAAC) questions were incorporated into the questionnaire. A cross-sectional study of children of the same age ten years apart, longitudinal studies on asthma incidence and remission as well as a cross-sectional study on vehicle traffic were performed. Results While children aged 7-8 years in 2006 more often had a physician-diagnosed asthma compared to children of the same age in 1996 (7.4% vs 5.7%, p<0.001), they had less asthma symptoms, especially severe symptoms. In parallel, a more beneficial environment and a more intense treatment with inhaled corticosteroids (ICS) were observed. The explanation for this change in clinical expression probably includes also an increased awareness and diagnosing of asthma. From age 12 years to age 19 years, the cumulative incidence of physician-diagnosed asthma was 7.2% and of current wheeze 22.0%. The risk of new-onset asthma in adolescence was increased among girls, sensitized and those with heredity for asthma. Smoking and home dampness increased the risk for incident wheeze. The risk for both incident asthma and wheeze was inversely related to number of siblings. Among children with current asthma at age 7-8 years, 21% were in remission, 38% had periodic asthma and 41% had persistent asthma at a follow-up at age 19 years. Subjects in remission and with periodic asthma had significantly less airway obstruction and showed less bronchial hyperreactivity compared to subjects with persistent asthma. The probability of asthma remission from childhood to early adulthood was significantly increased by absence of allergic sensitization, male gender and a low asthma severity scoring at age 7-8 years. Sensitization to furred animals was more important as a determinant of both incidence and remission than sensitization to pollen. Living close to roads with high traffic flows, especially with heavy vehicles, was associated with an increased risk for current wheeze. Stratified analyses showed that the effect of traffic on asthma and wheeze was restricted to non-sensitized subjects. Conclusion Asthma onset in adolescence was more common among girls and remission was more common among boys. Children sensitized to furred animals and children with a more severe asthma were risk groups for persistence of asthma. Environmental factors such as smoking and dampness were associated to onset of asthma symptoms during adolescence, and vehicle traffic was associated with asthma symptoms among children also in a small city with relatively low traffic flows. Preventive measures like smoking reduction programs, improvement of damp housing conditions and separation of areas where many children live from heavily trafficked roads could prove to be beneficial.

Resumen

This thesis represents an exploratory and iterative study into the relationships of Australian native plants from the family Myrtaceae, with respiratory symptoms, specifically asthma. This relationship is explored from a chemo-taxonomic stance and the connections with other plants with related chemotaxonomy are underlined. The research was performed against a background of geographical comparison between an urban coastal area and a rural mountainous area 90 kilometres just north of Brisbane, Queensland, Australia. The focus was the possible contribution of Melaleuca quinquenervia to the occurrence of autumn respiratory symptoms, especially asthma. The research challenges current beliefs that wind-pollinated plants are the only sources of allergens and the major botanical health threat for those who suffer with asthma. There is some critical analysis of the current understanding of world patterns of asthma, with particular reference to the Global Initiative for Asthma (GINA) geographic compilations. In this study 380 children were skin-tested with a battery of commercial allergens including Eucalyptus. Comparisons among children from three coastal schools and students from one mountain school were made with a view to testing the hypothesis that proximate vegetation would affect responses to allergens. As hypothesised, significant differences were detected between the coastal and range students in responses to Eucalyptus, which flowers prolifically on the coast. Coastal children, compared to the rural children from the mountain area exhibited a significantly greater percentage of skin-test responses (p≤.05) to Eucalyptus, when all responses greater than zero were measured. In the next phase more comparisons were undertaken with a smaller group of adults and adolescents in the coast and range communities. A range of terpenes and oxidized terpenes was applied during skin tests along with commercial allergens. Coastal and range reaction profiles revealed that coastal participants exhibit greater skin reactivity. When a 3mm wheal cut-off is employed alpha-pinene response in the range group is notable. During this second phase ambient air sampling was carried out at the same time as participants measured peak expiratory flow (PEF) and recorded respiratory symptoms. Chemicals trapped on Tenax over spring and autumn were analysed via GCMS and the results combined with symptom variables to ascertain significant predictors of symptom change. Using stepwise and general linear regression significant relationships were demonstrated between PEF and beta pinene and limonene in ambient air. In both types of modelling several terpenes were shown to be significant predictors of respiratory symptoms. In the coastal group the addition of alpha or beta pinene to a General Linear Regression model predicting standardized peak flow, accounted to an additional 20% of the variance in autumn. The model consisted of ozone, nitrogen dioxide and particulates less than 10 micron, all lagged three days. For spring, the additional variance explained was only 6 % and for spring an autumn combined it was 5%. Significant relationships were also demonstrated between linalool levels and preventer and reliever usage. The results support the hypotheses regarding the role of terpenes as having a possible role in the acquisition and exacerbation of asthma. Additionally a number of floral studies resulted in chemical profiles being elucidated for flowers from popular plants in Australia. Tenax collections of vapours from some household and lifestyle products resulted in chemical profiles for popular items. In conclusion, some observations about vegetation and patterns of asthma have been made and a new model of asthma acquisition proposed.

Resumen

The overall aims of our studies were to identify risk factors for respiratory symptoms and asthma in indoor environment but even to look at some personal risk factors such as body mass index and gastroesophageal reflux. The study population is based on participants of the European Community Respiratory Health Survey I and II.

In the first study, water damage and visible moulds were reported in 7.4% and 17% of the homes respectively. The combination of water damage and visible moulds was independently associated with attacks of breathlessness when resting and after activity and also to long term cough. In the second study, the prevalence of nocturnal GER increased with higher BMI and the same pattern could be seen for habitual snoring. Reported onset of asthma, wheeze and night-time symptoms increased in prevalence along with the BMI gradient. In the multivariable analysis, obesity and nocturnal GER were independent risk factors for onset of asthma, wheeze and night-time symptoms. Habitual snoring was an independent risk factor for onset of wheeze and night-time symptoms, but not for onset of asthma. In the third study, a total of 18% of the subjects reported indoor dampness in the last 12 months and 27% of the subjects reported indoor dampness since the previous survey. Respiratory symptoms and asthma were significantly more prevalent in individuals exposed to indoor dampness and indoor dampness was a risk factor for respiratory symptoms and asthma after adjusting for possible confounders. Indoor dampness was an independent risk factor for onset of respiratory symptoms but not for asthma onset. Remission of respiratory symptoms was less likely to occur if subjects reported indoor dampness. In the fourth study, the lowest prevalence of atopy and the lowest levels of all indoor allergens, bacteria and moulds were found in Iceland. A positive association was found, between cat allergen exposure and asthma symptoms and between bronchial hyperresponsiveness and the amount of viable mould in indoor air.

Resumen

Aim: The aim of this project was to study the age and sex specific occurrence of atopic and non-atopic asthma and other atopic manifestations in a nationwide sample of Swedish pre-school children. Methods: All 70 allergen avoidance day-care centres (AADC) with 84 sections and 140 matched ordinary day-care centres with 440 sections in 62 municipalities across Sweden were sampled. In 2000 the staff at each section responded to a questionnaire on indoor and outdoor environment at the section. In 2002 parents of 5,886 children attending the AADCs and ODCs responded to a postal questionnaire regarding symptoms indicating prevalent asthma, allergic rhinitis, eczema, and food, furred pet and pollen allergy and other data in their children. In 2007, parents of 4255 children responded to an almost identical follow-up questionnaire. Results: The AADCs had far more strict rules than ODCs on furred pets and smoking at home and on perfume use, and the indoor environment was better, owing to better cleaning. The age specific asthma prevalence was curvilinear with a peak at age 3 of 11.4% among boys and 9.8% among girls. In addition the prevalence increased by municipality population density, a proxy for degree of urbanisation. There was a highly significant co-occurrence between all asthma-atopic manifestations, but there was no evidence of ordered sequence of manifestation onset. The asthma incidence was highly dependent on presence or absence of co-occurrence variables. Given the variable mix in the present study population, the annual asthma incidence ranged from 0.6% to 1.2%. Conclusions: AADCs had more strict rules and a better indoor environment than ODCs. The asthma prevalence was affected by age, sex and degree of urbanisation. There was close co-occurrence between all asthma and atopic manifestations but no evidence of ordered sequence of onsets. The annual asthma incidence was strongly dependent of co-occurrence conditions.

Resumen

This chapter focuses on acute asthma and bronchospasm occurring in the perioperative period. Over 6% of the people in the United States have asthma, which is characterized by chronic inflammation, airway hyperresponsiveness, excessive mucus, and reversible airway obstruction. Due to generalized airway hyperreactivity, a history of asthma increases the risk of coughing, wheezing, bronchospasm, and oxygen desaturation. Although the incidence of bronchospasm associated with asthma is low, when it occurs it is often severe. A stepwise treatment algorithm is defined, which covers the use of first line agents such as inhaled beta-2 agonists and steroids, but also agents that are useful for refractory cases such as epinephrine, magnesium, and possibly ketamine.

Resumen

The incidence of asthma in children varies among countries and can be estimated to range between 5% and 20%. Exercise-induced asthma (EIA) is common in patients with asthma but can also occur in some children without asthma. Typical symptoms of EIA include cough, chest tightness, and shortness of breath shortly after exercise. The pathophysiology of EIA is not completely understood, but it has been shown that airway cooling and drying with increased ventilation during exercise and airway re-warming after exercise play a pivotal role. In addition, a lack of physical activity may also contribute to EIA. Regular exercise may increase fitness and psychological well-being but may also positively influence airway inflammation in children with asthma. The diagnosis of EIA is based on the typical history and may be verified by an exercise challenge test. Every child with EIA should be able to engage in all type of physical activities.

Resumen

Placebo effect is an example of ‘contextual’ effect and is the symptomatic improvement experienced by patients who have unknowingly received a placebo (inactive treatment) instead of an active drug. It occurs due to patient-specific factors such as expectation of improvement and is influenced by the context in which the treatment is delivered. Nocebo effect is the opposite of placebo effect and includes worsening of symptoms or incident adverse effects due to expectancy or negative contextual or practitioner influence. Placebo effect has been demonstrated in a range of musculoskeletal conditions, including osteoarthritis (OA), as well as other conditions such as Parkinson’s disease, irritable bowel syndrome, and asthma. In OA, the placebo effect is strongest for subjective outcomes like pain. In fact, the effect size (ES) of placebo analgesia in OA clinical trials (0.51) is clinically significant and higher than the ES (defined by the additional improvement above placebo) obtained from non-pharmacological (0.25) and pharmacological (0.39) treatments. A number of patient- and intervention-specific and contextual factors influence the magnitude of placebo-induced improvements. Placebo analgesia is real, not a ‘trick of the mind’, and results from central mechanisms that increase descending inhibition of pain. Contextual effects are an integral part of everyday clinical practice. While patient- and intervention-specific determinants cannot be changed easily, healthcare practitioners should optimize the physician-specific factors that enhance positive contextual response and minimize nocebo response. Such a strategy that will increase the overall improvement is particularly relevant for OA where there is no ‘cure’ and a predominance of negative beliefs.

Resumen

There are multiple well-recognized environmental factors that contribute to asthma exacerbation. Exposures to many of them will get unrecognized and most of the time will remain constant without knowing it is the causative agent. For an early identification of exposures and causative agents, a systematic approach needs to be taken in consideration by the encountering physician. Multiple questionnaires had been implementing and discussing organic and inorganic factors as well intrinsic and extrinsic factors. It is well-recognized that environmental exposures can cause worsening of asthma, other allergic conditions and even more severe pulmonary diseases. Asthma is a very prevalent disease with increased incidence nowadays. In the last decade, multiple new medications had been discovered for the treatment of moderate-to-severe persistent asthma, which most of them target the cellular component of the disease such as eosinophils and specific Immunoglobins. In the era of personalized medicine, environmental and occupational factors in asthma are key players that need to be recognized early in this patient population. In this chapter will go over model of effects, mechanism of action of these environmental factors, recognition, course of action and management of this patient population.

Resumen

Eosinophilic esophagitis also known as asthma of the esophagus is a food-related allergic disorder of the esophagus widely distributed all over the world. The incidence and prevalence of eosinophilic esophagitis have been increasing over the last few decades. The pathogenesis of this entity is now better understood and three distinct endotypes have been defined for better management strategy. Diagnosis is made on the basis of clinical symptoms followed by endoscopy with biopsy. Drugs, diet and endoscopic dilation are the current modalities of treatment. IL-4 and IL-13 inhibitors have been found to be promising in clinical trials.

Resumen

Chronic pelvic pain (CPP) is a common gynaecological complaint with a similar consultation rate to low back pain, asthma, or migraine. It is estimated that up to 15–20% of women aged 18–50 years have experienced CPP for more than 1 year. Nevertheless, the incidence of CPP is likely to be underestimated due to under-reporting. CPP is a condition distressing to patients and challenging to gynaecologists. It is commonly associated with endometriosis, adhesions, pelvic inflammatory disease, as well as a variety of urological, gastrointestinal, musculoskeletal, or psychosocial conditions. This chapter provides a general overview of the condition, with a special emphasis on the management strategy in dealing with patients with this condition.

Texto completo

Resumen

Nowadays, large quantities of banned chemical pesticides are still in use illegally in various developing countries. The effect of these pesticides on humans, that is, children, adults, including pregnant women, either through chronic residential or occupational exposure, leads to various negative effects. This chapter focuses on the evidence of using the banned pesticides in developing countries and the occurrence of different diseases that affect the quality of life of the affected individuals either at the health, social, and/or labor level. The recorded diseases included obesity, diabetes, Alzheimer’s, dementia, Parkinson’s, asthma, chronic bronchitis, autism, erectile dysfunction, and psychological disorders as a result of chronic exposure to the banned pesticides. It was highlighted the identification of each disease, some epidemiological studies carried out in developing countries, and the mechanisms of action by which the pesticides are linked to each mentioned disease. In conclusion, it was discussed the major causes behind the incidence of such diseases and suggested suitable solutions that must be presented by the US Environmental Protection Agency, Food and Agriculture Organization among other bodies to the developing countries to avoid and overcome the occurrence of such diseases in the future.

Resumen

The term “failure” can be defined as the inability of a part or assembly to perform its intended function. Despite the significant technological advances, failure incidents frequently occur, thus, causing human and financial consequences. The failure analysis is a crucial engineering tool. It aims to avoid similar cases in the future, thereby preventing accidents, reducing economic losses due to stopping plant production and keeping the environment safe. Furthermore, the failure analysis contributes to redesign, solve manufacturing drawbacks, save money and time, and in some cases, prevents fatality and saves lives. Conversely, failures can also improve engineering practices; indeed, through analyzing failures and implementing preventive measures, significant advances have been obtained in the quality of products and systems. Moreover, a beneficial outcome of failure analysis has been improved codes and specifications governing materials, for instance, API, ASTM, and ASME. In the current chapter, the failure analysis methodology will be discussed in detail with practical examples to know how to perform analysis for any failure cases, particularly in the oil and gas industry.
