The Bryce Group was a loose organisation of British Liberal Party members which was devoted to studying international organisation. The organization was the first to fully flesh out a blueprint for a League of Nations and organize a popular movement around establishing the League.
80-837: The group was founded in 1914 by Goldsworthy Lowes Dickinson , and some of its early meetings were attended by Viscount Bryce . Bryce chaired the Committee on Alleged German Outrages , and its 1915 report, popularly known as the "Bryce Report", became the focus of much of the group's work. The group concluded that, to minimise future atrocities, nations should agree on a binding treaty, which would compel them to take disputes to arbitration, and provide sanctions against both signatories and non-signatories, to compel them to accept this arbitration. Some group members disagreed with these conclusions; for example, Arthur Ponsonby objected to all use of force, while John A. Hobson believed that any international organisation would be ineffective unless it had
160-603: A Forecast (1905) and Religion and Immortality (1911). Within a fortnight of the start of the First World War , Dickinson had drafted schemes for a "League of Nations", and together with Lord Dickinson and Lord Bryce he planned the ideas behind of the League of Nations and played a leading role in the founding of the group of internationalist pacifists known as the Bryce Group . The organisation eventually became
240-406: A combination of factors, including poor treatment adherence, increased allergen and viral exposure, and altered immune tolerance. There is limited evidence to guide possible approaches to reducing autumn exacerbations, but while costly, seasonal omalizumab treatment from four to six weeks before school return may reduce autumn asthma exacerbations. Asthma is the result of chronic inflammation of
320-456: A common cause of acute attacks in women and children. Both viral and bacterial infections of the upper respiratory tract can worsen the disease. Psychological stress may worsen symptoms – it is thought that stress alters the immune system and thus increases the airway inflammatory response to allergens and irritants. Asthma exacerbations in school-aged children peak in autumn, shortly after children return to school. This might reflect

When the boy was about one year old his family moved to the Spring Cottage in Hanwell , then a country village. The family also included his brother, Arthur, three years older, an older sister, May, and two younger sisters, Hester and Janet. His education included attendance at
480-578: A day school in Somerset Street, Portman Square , when he was ten or eleven. At about the age of twelve, he was sent to Beomonds, a boarding school in Chertsey , and his teenage years from 14 to 19 were spent at Charterhouse School in Godalming , where his brother Arthur had preceded him. He was unhappy at Charterhouse, although he enjoyed seeing plays put on by visiting actors, and he played
560-679: A deeper kind. Dickinson was a lecturer in political science from 1886 to his retirement in 1920, and the college librarian from 1893 to 1896. Dickinson helped establish the Economics and Politics Tripos and taught political science within the University. For 15 years he also lectured at the London School of Economics . In 1897 he made his first trip to Greece , travelling with Nathaniel Wedd, Robin Mayor , and A. M. Daniel . He joined

Within a fortnight of the war's breaking out, he drew up the idea of a League of Nations , and his subsequent writings helped to shape public opinion towards the creation of the League. Within the field of international relations , Dickinson is prominent for popularizing conceptions of

Asthma is thought to be caused by a combination of genetic and environmental factors . Environmental factors include exposure to air pollution and allergens . Other potential triggers include medications such as aspirin and beta blockers . Diagnosis is usually based on
800-609: A good friend, who had been influenced by Dickinson's books, accepted the appointment as Dickinson's literary executor. Dickinson's sisters then asked Forster to write their brother's biography, which was published as Goldsworthy Lowes Dickinson in 1934. Forster has been criticised for refraining from publishing details of Dickinson's sexual proclivities, including his foot fetishism and unrequited love for young men. E. M. Forster stated (in "the Art of Fiction") that he used Dickinsons' sisters as his inspiration for Margaret and Helen Schlegel,
880-580: A large number of books and pamphlets, including his book The International Anarchy . He also attended a pacifist conference in The Hague in 1915, and in 1916 he set off on a lecture tour of the United States promoting the idea of a League of Nations. In the 1920s, Dickinson joined the Labour Party , and he was appointed to the party's Advisory Committee on International Questions. In 1929,

But the contrast which he offers between Christianity and Paganism in the matter of moral ideals—a contrast which he states very ably in a paper called "How Long Halt Ye?" which appeared in the Independent Review —does, I think, contain an error of
1040-412: A person's asthma is controlled. The methacholine challenge involves the inhalation of increasing concentrations of a substance that causes airway narrowing in those predisposed. If negative it means that a person does not have asthma; if positive, however, it is not specific for the disease. Other supportive evidence includes: a ≥20% difference in peak expiratory flow rate on at least three days in
1120-413: A significantly higher risk compared to randomly selected controls ( odds ratio 7.2, 95% confidence interval 5.2–10). Asthma phenotyping and endotyping has emerged as a novel approach to asthma classification inspired by precision medicine which separates the clinical presentations of asthma, or asthma phenotypes, from their underlying causes, or asthma endotypes. The best-supported endotypic distinction
1200-585: A third of people. This may be even more common in some ethnic groups such as the Japanese and those with aspirin-exacerbated respiratory disease. Other studies have found improvement in asthmatic symptoms from alcohol. Non-atopic asthma, also known as intrinsic or non-allergic, makes up between 10 and 33% of cases. There is negative skin test to common inhalant allergens. Often it starts later in life, and women are more commonly affected than men. Usual treatments may not work as well. The concept that "non-atopic"
1280-429: A trigger for asthma; formaldehyde exposure, for example, has a positive association. Phthalates in certain types of PVC are associated with asthma in both children and adults. While exposure to pesticides is linked to the development of asthma, a cause and effect relationship has yet to be established. A meta-analysis concluded gas stoves are a major risk factor for asthma, finding around one in eight cases in
1360-432: A week for at least two weeks, a ≥20% improvement of peak flow following treatment with either salbutamol, inhaled corticosteroids or prednisone, or a ≥20% decrease in peak flow following exposure to a trigger. Testing peak expiratory flow is more variable than spirometry, however, and thus not recommended for routine diagnosis. It may be useful for daily self-monitoring in those with moderate to severe disease and for checking
1440-1016: Is a commonly reported occupational disease . Many cases, however, are not reported or recognized as such. It is estimated that 5–25% of asthma cases in adults are work-related. A few hundred different agents have been implicated, with the most common being isocyanates , grain and wood dust, colophony , soldering flux , latex , animals, and aldehydes . The employment associated with the highest risk of problems include those who spray paint , bakers and those who process food, nurses, chemical workers, those who work with animals, welders , hairdressers and timber workers. Aspirin-exacerbated respiratory disease (AERD), also known as aspirin -induced asthma, affects up to 9% of asthmatics. AERD consists of asthma, nasal polyps, sinus disease, and respiratory reactions to aspirin and other NSAID medications (such as ibuprofen and naproxen). People often also develop loss of smell and most experience respiratory reactions to alcohol. Alcohol may worsen asthmatic symptoms in up to
1520-429: Is a history of atopic disease ; with asthma occurring at a much greater rate in those who have either eczema or hay fever . Asthma has been associated with eosinophilic granulomatosis with polyangiitis (formerly known as Churg–Strauss syndrome), an autoimmune disease and vasculitis . Individuals with certain types of urticaria may also experience symptoms of asthma. There is a correlation between obesity and
1600-456: Is a kind of asthma distinguishable by recurrent, severe attacks. Type 1 brittle asthma is a disease with wide peak flow variability, despite intense medication. Type 2 brittle asthma is background well-controlled asthma with sudden severe exacerbations. Exercise can trigger bronchoconstriction both in people with or without asthma. It occurs in most people with asthma and up to 20% of people without asthma. Exercise-induced bronchoconstriction
1680-503: Is a specific single nucleotide polymorphism in the CD14 region and exposure to endotoxin (a bacterial product). Endotoxin exposure can come from several environmental sources including tobacco smoke, dogs, and farms. Risk for asthma, then, is determined by both a person's genetics and the level of endotoxin exposure. A triad of atopic eczema , allergic rhinitis and asthma is called atopy. The strongest risk factor for developing asthma

#17327659131781760-499: Is a well-recognized condition, there is not one universal agreed-upon definition. It is defined by the Global Initiative for Asthma as "a chronic inflammatory disorder of the airways in which many cells and cellular elements play a role. The chronic inflammation is associated with airway hyper-responsiveness that leads to recurrent episodes of wheezing, breathlessness, chest tightness and coughing particularly at night or in
1840-732: Is affected, the probability of the other having the disease is approximately 25%. By the end of 2005, 25 genes had been associated with asthma in six or more separate populations, including GSTM1 , IL10 , CTLA-4 , SPINK5 , LTC4S , IL4R and ADAM33 , among others. Many of these genes are related to the immune system or modulating inflammation. Even among this list of genes supported by highly replicated studies, results have not been consistent among all populations tested. In 2006 over 100 genes were associated with asthma in one genetic association study alone; more continue to be found. Some genetic variants may only cause asthma when they are combined with specific environmental exposures. An example
1920-531: Is associated with a greater risk of asthma-like symptoms. Low air quality from environmental factors such as traffic pollution or high ozone levels has been associated with both asthma development and increased asthma severity. Over half of cases in children in the United States occur in areas when air quality is below the EPA standards. Low air quality is more common in low-income and minority communities. Exposure to indoor volatile organic compounds may be
2000-500: Is associated with an increased risk of asthma in the child. Some individuals will have stable asthma for weeks or months and then suddenly develop an episode of acute asthma. Different individuals react to various factors in different ways. Most individuals can develop severe exacerbation from a number of triggering agents. Home factors that can lead to exacerbation of asthma include dust , animal dander (especially cat and dog hair), cockroach allergens and mold . Perfumes are
2080-504: Is associated with exposure to indoor allergens. Common indoor allergens include dust mites , cockroaches , animal dander (fragments of fur or feathers), and mould. Efforts to decrease dust mites have been found to be ineffective on symptoms in sensitized subjects. Weak evidence suggests that efforts to decrease mould by repairing buildings may help improve asthma symptoms in adults. Certain viral respiratory infections, such as respiratory syncytial virus and rhinovirus , may increase
2160-435: Is attributed to the lack of healthy bacterial colonization that the newborn would have acquired from passage through the birth canal. There is a link between asthma and the degree of affluence which may be related to the hygiene hypothesis as less affluent individuals often have more exposure to bacteria and viruses. Family history is a risk factor for asthma, with many different genes being implicated. If one identical twin
2240-977: Is believed that the recent increased rates of asthma are due to changing epigenetics ( heritable factors other than those related to the DNA sequence ) and a changing living environment. Asthma that starts before the age of 12 years old is more likely due to genetic influence, while onset after age 12 is more likely due to environmental influence. Many environmental factors have been associated with asthma's development and exacerbation, including allergens, air pollution, and other environmental chemicals. There are some substances that are known to cause asthma in exposed people and they are called asthmagens . Some common asthmagens include ammonia, latex, pesticides, solder and welding fumes, metal or wood dusts, spraying of isocyanate paint in vehicle repair, formaldehyde, glutaraldehyde, anhydrides, glues, dyes, metal working fluids, oil mists, moulds. Smoking during pregnancy and after delivery
2320-427: Is classified based on severity, at the moment there is no clear method for classifying different subgroups of asthma beyond this system. Finding ways to identify subgroups that respond well to different types of treatments is a current critical goal of asthma research. Recently, asthma has been classified based on whether it is associated with type 2 or non–type 2 inflammation. This approach to immunologic classification
2400-437: Is common in professional athletes. The highest rates are among cyclists (up to 45%), swimmers, and cross-country skiers. While it may occur with any weather conditions, it is more common when it is dry and cold. Inhaled beta 2 agonists do not appear to improve athletic performance among those without asthma; however, oral doses may improve endurance and strength. Asthma as a result of (or worsened by) workplace exposures
2480-464: Is commonly referred to as an asthma attack . The classic symptoms are shortness of breath , wheezing , and chest tightness . The wheezing is most often when breathing out. While these are the primary symptoms of asthma, some people present primarily with coughing , and in severe cases, air motion may be significantly impaired such that no wheezing is heard. In children, chest pain is often present. Signs occurring during an asthma attack include

2560-430: Is correlated with more exposure to cigarette smoke, an older age, less symptom reversibility after bronchodilator administration, and decreased likelihood of family history of atopy. The evidence for the effectiveness of measures to prevent the development of asthma is weak. The World Health Organization recommends decreasing risk factors such as tobacco smoke, air pollution, chemical irritants including perfume , and
2640-436: Is driven by a developing understanding of the underlying immune processes and by the development of therapeutic approaches that target type 2 inflammation. Although asthma is a chronic obstructive condition, it is not considered as a part of chronic obstructive pulmonary disease , as this term refers specifically to combinations of disease that are irreversible such as bronchiectasis and emphysema . Unlike these diseases,
2720-399: Is insufficient, the use of medication is recommended. Pharmaceutical drugs are selected based on, among other things, the severity of illness and the frequency of symptoms. Specific medications for asthma are broadly classified into fast-acting and long-acting categories. The medications listed below have demonstrated efficacy in improving asthma symptoms; however, real world use-effectiveness
2800-537: Is limited as around half of people with asthma worldwide remain sub-optimally controlled, even when treated. People with asthma may remain sub-optimally controlled either because optimum doses of asthma medications do not work (called "refractory" asthma) or because individuals are either unable (e.g. inability to afford treatment, poor inhaler technique) or unwilling (e.g., wish to avoid side effects of corticosteroids) to take optimum doses of prescribed asthma medications (called "difficult to treat" asthma). In practice, it
2880-408: Is no known cure for asthma, but it can be controlled. Symptoms can be prevented by avoiding triggers, such as allergens and respiratory irritants , and suppressed with the use of inhaled corticosteroids . Long-acting beta agonists (LABA) or antileukotriene agents may be used in addition to inhaled corticosteroids if asthma symptoms remain uncontrolled. Treatment of rapidly worsening symptoms
2960-434: Is not known whether asthma causes psychological problems or psychological problems lead to asthma. Current asthma, but not former asthma, is associated with increased all-cause mortality, heart disease mortality, and chronic lower respiratory tract disease mortality. Asthma, particularly severe asthma, is strongly associated with development of chronic obstructive pulmonary disease (COPD). Those with asthma, especially if it
3040-452: Is not possible to distinguish "refractory" from "difficult to treat" categories for patients who have never taken optimum doses of asthma medications. A related issue is that the asthma efficacy trials upon which the pharmacological treatment guidelines are based have systematically excluded the majority of people with asthma. For example, asthma efficacy treatment trials always exclude otherwise eligible people who smoke, and smoking diminishes
3120-478: Is poorly controlled, are at increased risk for radiocontrast reactions. Cavities occur more often in people with asthma. This may be related to the effect of beta 2 -adrenergic agonists decreasing saliva. These medications may also increase the risk of dental erosions . Asthma is caused by a combination of complex and incompletely understood environmental and genetic interactions. These influence both its severity and its responsiveness to treatment. It
3200-421: Is supportive of the diagnosis. It however may be normal in those with a history of mild asthma, not currently acting up. As caffeine is a bronchodilator in people with asthma, the use of caffeine before a lung function test may interfere with the results. Single-breath diffusing capacity can help differentiate asthma from COPD . It is reasonable to perform spirometry every one or two years to follow how well

3360-722: Is the type 2-high/type 2-low distinction. Classification based on type 2 inflammation is useful in predicting which patients will benefit from targeted biologic therapy . Many other conditions can cause symptoms similar to those of asthma. In children, symptoms may be due to other upper airway diseases such as allergic rhinitis and sinusitis , as well as other causes of airway obstruction including foreign body aspiration , tracheal stenosis , laryngotracheomalacia , vascular rings , enlarged lymph nodes or neck masses. Bronchiolitis and other viral infections may also produce wheezing. According to European Respiratory Society , it may not be suitable to label wheezing preschool children with

Dickinson did not live the detached life of a stereotypical Cambridge academic. When G. K. Chesterton chose contemporary thinkers with whom he disagreed for his book Heretics (1905),
4240-471: The age of 65, most people with obstructive airway disease will have asthma and COPD. In this setting, COPD can be differentiated by increased airway neutrophils, abnormally increased wall thickness, and increased smooth muscle in the bronchi. However, this level of investigation is not performed due to COPD and asthma sharing similar principles of management: corticosteroids, long-acting beta-agonists, and smoking cessation. It closely resembles asthma in symptoms,
4320-616: The airway obstruction in asthma is usually reversible; however, if left untreated, the chronic inflammation from asthma can lead the lungs to become irreversibly obstructed due to airway remodelling. In contrast to emphysema, asthma affects the bronchi, not the alveoli . The combination of asthma with a component of irreversible airway obstruction has been termed the asthma-chronic obstructive disease (COPD) overlap syndrome (ACOS) . Compared to other people with "pure" asthma or COPD, people with ACOS exhibit increased morbidity, mortality and possibly more comorbidities. An acute asthma exacerbation
4400-466: The airways include an increase in eosinophils and thickening of the lamina reticularis . Chronically the airways' smooth muscle may increase in size along with an increase in the numbers of mucous glands. Other cell types involved include T lymphocytes , macrophages , and neutrophils . There may also be involvement of other components of the immune system , including cytokines , chemokines , histamine , and leukotrienes among others. While asthma

4560-674: The central characters in Howards End . Posthumous: Asthma Asthma is a common long-term inflammatory disease of the airways of the lungs . Asthma occurs when allergens , pollen , dust, or other particles, are inhaled into the lungs, causing the bronchioles to constrict and produce mucus, which then restricts oxygen flow to the alveoli . It is characterized by variable and recurring symptoms, reversible airflow obstruction , and easily triggered bronchospasms . Symptoms include episodes of wheezing , coughing , chest tightness, and shortness of breath . These may occur

Evidence supporting the hygiene hypothesis includes lower rates of asthma on farms and in households with pets. Use of antibiotics in early life has been linked to the development of asthma. Also, delivery via caesarean section is associated with an increased risk (estimated at 20–80%) of asthma – this increased risk

There is currently no precise test for the diagnosis, which is typically based on the pattern of symptoms and response to therapy over time. Asthma may be suspected if there is a history of recurrent wheezing, coughing or difficulty breathing and these symptoms occur or worsen due to exercise, viral infections, allergens or air pollution.

In contrast to many of his contemporaries who attributed the causes of war to national and imperial expansion or to population growth, Dickinson argued that war was rooted in fear and suspicion caused by anarchy and arms races. Dickinson was born in London, the son of Lowes Cato Dickinson (1819–1908), a portrait painter, by his marriage to Margaret Ellen Williams,

He felt that the secret diplomacy of the early twentieth century had brought about war and thus could write that, "the impossibility of war, I believe, would be increased in proportion as the issues of foreign policy should be known to and controlled by public opinion." Dickinson promoted his ideas with

Other efforts that show promise include: limiting smoke exposure in utero , breastfeeding , and increased exposure to daycare or large families, but none are well supported enough to be recommended for this indication. Early pet exposure may be useful. Results from exposure to pets at other times are inconclusive and it is only recommended that pets be removed from

Acute severe asthma , previously known as status asthmaticus, is an acute exacerbation of asthma that does not respond to standard treatments of bronchodilators and corticosteroids. Half of cases are due to infections with others caused by allergen, air pollution, or insufficient or inappropriate medication use. Brittle asthma
5600-504: The rates have increased significantly since the 1960s. Asthma was recognized as early as Ancient Egypt . The word asthma is from the Greek ἆσθμα , âsthma , which means 'panting'. Asthma is characterized by recurrent episodes of wheezing , shortness of breath , chest tightness , and coughing . Sputum may be produced from the lung by coughing but is often hard to bring up. During recovery from an asthma attack (exacerbation) ,
5680-653: The risk of asthma with both having increased in recent years. Several factors may be at play including decreased respiratory function due to a buildup of fat and the fact that adipose tissue leads to a pro-inflammatory state. Beta blocker medications such as propranolol can trigger asthma in those who are susceptible. Cardioselective beta-blockers , however, appear safe in those with mild or moderate disease. Other medications that can cause problems in asthmatics are angiotensin-converting enzyme inhibitors , aspirin , and NSAIDs . Use of acid-suppressing medication ( proton pump inhibitors and H2 blockers ) during pregnancy
5760-550: The risk of developing asthma when acquired as young children. Certain other infections, however, may decrease the risk. The hygiene hypothesis attempts to explain the increased rates of asthma worldwide as a direct and unintended result of reduced exposure, during childhood, to non-pathogenic bacteria and viruses. It has been proposed that the reduced exposure to bacteria and viruses is due, in part, to increased cleanliness and decreased family size in modern societies. Exposure to bacterial endotoxin in early childhood may prevent
5840-721: The spring of 1886, Dickinson joined the University Extension Scheme to give public lectures that covered Carlyle , Emerson , Browning , and Tennyson .
