Zahlreiche Studien belegen schädigende Assoziationen zwischen Atemwegserkrankungen und gasförmigen und partikulären Luftschadstoffen. Feinstaub erwies sich als besonders schädigend. Es ist jedoch noch nicht geklärt, welche Partikelfraktionen des Feinstaubes für die Zusammenhänge verantwortlich sind. In dieser Arbeit werden die Kurzzeit-Effekte von grobem Feinstaub (TSP) sowie den gasförmigen Schadstoffen Schwefeldioxid (SO2) und Stickstoffdioxid (NO2) auf Krankenhauseinweisungen aufgrund von Atemwegserkrankungen in Drobeta, Rumänien untersucht. Zudem wird der Zusammenhang von PM10 (Partikel mit einem Durchmesser < 10 µm), NO2, SO2 und größenabhängigen Partikelanzahlkonzentrationen (PNC) mit respiratorischen Notfallaufnahmen und Sterbefällen in Peking, China, analysiert. Für Peking wird zudem ein statistisches Modell entwickelt, um fehlende PNC zu modellieren. Ziel der Arbeit ist es, die relevanten Faktoren in den Beziehungen zwischen Atemwegserkrankungen und Luftverschmutzung, vor allem Feinstaub, zu untersuchen. In beiden Städten wurde ein schädigender Einfluss von Luftschadstoffen auf Atemwegserkrankungen festgestellt. In Drobeta waren TSP und SO2 mit Atemwegserkrankungen assoziiert, wobei der schädigende Einfluss von TSP durch trockene Luft verstärkt wurde. In Peking zeigten vor allem Akkumulationspartikel (Durchmesser 0.1 – 1 µm) eine schädigende Wirkung, welche für ultrafeine Partikel (UFP, < 100 nm) nicht festgestellt werden konnte. Dabei war der Einfluss von PNC unabhängig von PM10. Der Effekt von PNC war für stagnierende Luftmassen größer, was darauf hinweist, dass neben der Partikelanzahl und -oberfläche die Partikelchemie einen negativen Einfluss hat. Darüber hinaus wurde eine Assoziation von NO2 mit Notfallaufnahmen und von SO2 mit der Mortalität festgestellt. Die Ergebnisse bestätigen den schädigenden Einfluss von gasförmigen sowie partikulären Luftschadstoffen auf Atemwegserkrankungen und weisen auf größenabhängige Effekte von Feinstaub hin. / Numerous epidemiological studies have described adverse effects of particulate and gaseous air pollution on respiratory health. Especially particulate matter (PM) seems to be relevant for the observed associations. However, it is not yet clear which particle fractions are responsible for the observed health effects of PM. In the presented studies, we analyse the short-term associations of total suspended particles (TSP) as well as of sulphur dioxide (SO2) and nitrogen dioxide (NO2) with respiratory hospital admissions in Drobeta, Romania. Moreover, effects of PM10 (PM with a diameter < 10 µm), NO2, SO2, and size-segregated particle number concentrations (PNC) on respiratory mortality and emergency room visits (ERV) are investigated for Beijing, China. For Beijing, we also develop a statistical model to impute missing PNC. The aim of the studies is to investigate the factors influencing the short term associations between respiratory health and air pollution, especially PM. Air pollution was adversely associated with respiratory health in Drobeta and Beijing. In Drobeta, TSP and SO2 were adversely associated with hospital admissions for chronic bronchitis; thereby, dry air aggravated the adverse associations of TSP. In Beijing, mostly accumulation mode particles (0.1 – 1 µm) showed adverse associations with respiratory health, whereas, there was a lack thereof for ultrafine particles (UFP). The effects of PNC were found to be independent of PM10. Adverse health effects of PNC were stronger for stagnant air masses indicating that, besides particle number and surface area, also particle chemistry influences the observed associations, as stagnant air masses result in chemically diverse particles. Also, NO2 was adversely associated with respiratory ERV and SO2 with respiratory mortality. These findings underline the strong influence of gaseous and particulate air pollution on respiratory health and indicate size dependent effects of particulate matter.

Respiratory diseases are ones of the most common diseases, which are treated by general practitioners. Not only the right diagnosis is essential, but the treatment as well. The treatment of respiratory diseases is usually long-term and often requires repeating. Health treatment of young children in a spa improves their life and health quality, inclusion in a collective of similar aged children, reduces complications of their disease, doses of medicine and highly reduces the risk of development of a chronical disease in adulthood. The aim of this thesis is to chart the use of coordinated rehabilitation in spa Lázně Luhačovice, a. s. and to survey coordinated rehabilitation awareness of spa medical and non medical personnel and children's accompaniment. Three hypotheses were set. Hypothesis 1: Children's accompaniment, who has been to spa health resort repeatedly percieves the care of his child as coordinated unlike the one who has been to spa health resort just once. Hypothesis 2: Medical staff of children spa health resorts percieves the most the medical treatment part of coordinated rehabilitation in contrast with non medical staff. Hypothesis 3: Children's accompaniment is satisfied the most with the medical treatment part of coordinated rehabilitation unlike the pedagogical and social one. A strategy of quantitative research was used, data was gathered by standardized questionnaires in June and July 2015. The standardized questionnaires were given to two different research groups. First one was spa health resort personnel, second one children's accompaniment in the spa Lázně Luhačovice, a. s. Based on statistical calculations the hypotheses can not be rejected, the results are not statistically significant. From the data obtained from the questionnaires, it is noticable that from the spa health resort medical and non medical personnel point of view, there is percieved only the part, which they provide. On the other hand, from the children's accompaniment point of view the rehabilitation is percieved as coordinated in all the parts provided. It is thanks to the fact that the accompaniment, who is in the spa health resort on the expenses of health insurance company, can see all the parts of coordinated rehabilitation as they undergo it together with their children. This thesis contributes to widening awareness of using parts of coordinated rehabilitation in children repeated respiratory diseases treatment, which are provided in facilities of spa Lázně Luhačovice, a.s. and in other health resorts, where there is this kind of care provided as well.

As infecções respiratórias agudas são uma importante causa de morbidade e mortalidade infantil em todo o mundo. Algumas dessas infecções podem resultar em Síndrome Respiratória Aguda Grave (SRAG). Os vírus respiratórios são os principais responsáveis por esta doença. O monitoramento e a vigilância das SRAG e dos vírus respiratórios são importantes para a gestão em saúde minimizando o impacto destas infecções respiratórias. O presente estudo buscou analisar a sazonalidade e impacto clínico das infecções causadas por vírus respiratórios em crianças internadas em hospital pediátrico do Paraná. Foram incluídos no estudo 229 pacientes de 0 até 15 anos de idade, de janeiro de 2012 a dezembro de 2015, com diagnóstico clínico de SRAG e amostra respiratória coletada e enviada ao Laboratório Central do Estado do Paraná para diagnóstico do agente etiológico. A busca dos casos de SRAG foi realizada utilizando o prontuário eletrônico GSUS (Gestão da Assistência de Saúde do SUS), arquivos do setor de fisioterapia e informações do Núcleo de Controle de Infecções hospitalares do hospital do estudo. Dos pacientes incluídos na pesquisa, foi preenchido um formulário de coleta de dados e posteriormente estes foram analisados de acordo com os objetivos da pesquisa. As análises estatísticas foram efetuadas com o pacote estatístico GRAPHPAD PRISM e foi considerado um nível de significância de 5%. A maioria dos pacientes da amostra pertencia à faixa etária de 0 a 6 meses de idade, não houve sexo predominante. No presente estudo as amostras positivas para pelo menos um agente etiológico contabilizaram 76,41%, e o vírus mais prevalente foi o Vírus Sincicial respiratório (VSR). Quanto à sazonalidade da detecção viral, houve predominância no final de outono e início do inverno, mais acentuada para o VSR. Quando analisada as três temperaturas ambientais da região, a incidência de SRAG foi significativamente maior no quartil descendente da temperatura média para mínima. Não foi observada diferença significativa entre os grupos etiológicos pesquisados com relação ao tempo desde o início dos sintomas até a internação. Houve predominância de internamentos em Unidade de Terapia Intensiva. O tempo de internamento foi significativamente maior naqueles pacientes com doença de base e não alterou conforme os agentes etiológicos identificados ou presença de codetecção. Os pacientes que apresentaram padrão misto na radiografia de tórax tiveram um tempo de internamento significativamente maior do que aqueles que apresentaram o padrão infiltrado intersticial. O tempo total foi significativamente menor no grupo Metapneumovírus em relação aos grupos Bordetella pertussis, Influenza, Rinovírus e grupo dos pacientes sem agentes infecciosos detectados. O tempo de ventilação mecânica não apresentou diferenças significativas entre os grupos etiológicos nem com relação à presença ou não de codetecção. A maior parte dos pacientes recebeu alta hospitalar, mas ocorreram três óbitos devido a SRAG, todos em pacientes com alguma doença de base ou condições de risco. / Acute respiratory infections are the most important cause of children morbidity and mortality worldwide. Some of these infections can result in Severe Acute Respiratory Syndrome (SARS). Respiratory viruses are primarily responsible for SARS. The monitoring and surveillance of SARS and respiratory viruses are important for health management, minimizing the impact of these respiratory infections. The present study was about the seasonality and clinical impact of respiratory viruses in children admitted to a pediatric reference hospital. The study included 229 children from 0 to 15 years old, from January 2012 to December 2015, with clinical diagnosis of SARS and respiratory sample collected and sent to the Central Laboratory of the State of Paraná for etiological agent analysis. The search for SARS cases was performed using the GSUS (Health Care Management of SUS) electronic filesystem, records of the center of physiotherapy and information of the Hospital Infection Control Center of the studied hospital. Of the patients included in the research, data collection forms were filled out and later analyzed according to the research objectives. Statistical analyzis were performed with the statistical package GRAPHPAD PRISM and a significance level of 5% was considered. The majority of patients in the sample belonged to the age group 0-6 months of age, and there was no predominant sex. Regarding the risk factors for viral infection, the presence of comorbidity or underlying disease was the most prevalent factor. In the present study, the positive samples for at least one etiological agent accounted for 76.41%, and the most prevalent virus was Respiratory Syncytial Virus (RSV). As for the seasonality of viral detection, there was a predominance in the late fall and early winter, which was more pronounced for RSV. When the environmental temperatures of the region were analyzed, the incidence of SARS was significantly higher in the descending quartile of the average minimum temperature. No significant difference was observed between the studied etiological groups in relation to the time from the beginning of the symptoms until the hospitalization. There was a predominance of hospitalizations in the Intensive Care Unit. The hospitalization time was significantly higher in patients with underlying disease or comorbidities and did not change according to the identified etiological agents or the presence of codetection. Patients who presented a mixed pattern on chest radiography had a significantly longer hospitalization time than those who had the interstitial infiltrate pattern. The total time was significantly lower in the Metapneumovirus group than in the Bordetella pertussis, Influenza, Rhinovirus and group of patients without detected infectious agents. Most patients were discharged from hospital, but there were three deaths due to SARS, all in patients with some underlying disease or risk conditions.

Objetivos: El proyecto tuvo el objetivo de mejorar el conocimiento de la población sobre la prevención de enfermedades respiratorias agudas en niños menores de 5 años. Para lograr esto se incidió en las principales 3 causas encontradas que eran los inadecuados hábitos de higiene en niños y cuidadores involucrados, la baja cobertura de vacunación en los niños menores de 5 años y la malnutrición en los niños que los predispone a padecer todo tipo de enfermedades. Metodología: Se siguió la metodología del marco lógico, se realizó en primer lugar una priorización de problemas y el análisis de involucrados, se esquematizó el árbol de problemas y árbol de objetivos, a continuación, se analizaron las alternativas de solución y se graficó la estructura analítica del proyecto, luego se realizó la matriz del marco lógico y finalmente se plantearon las actividades y tareas resumidas en la matriz de programación. Actividades: Se realizaron 2 actividades principales que consistieron en la realización de afiches y videos para presentar a la comunidad vía online debido a la coyuntura actual de la pandemia por Sars-CoV-2. Resultados: Los resultados del proyecto a corto plazo se midieron por encuestas de conocimiento respondidas por la comunidad, una antes de la intervención y otra después, siendo el logro final la mejora de conocimiento de la comunidad en materia de prevención de enfermedades respiratorias, reconocimiento de sus signos de alarma, importancia de la vacunación, alimentación saludable, métodos de higiene, lactancia materna, entre otros. / Introduction: This health intervention project was carried out in the Pacific Villa upper part human settlement, located in the district of Chorrillos, where the prevalence and mortality from respiratory diseases in children under 5 years of age is high and represents a health problem. Objectives: The project had the objective of improving the population’s knowledge about prevention of acute respiratory diseases in children under 5 years of age. To achieve this, the main 3 causes found were involved, which were inadequate hygiene habits in children and their caregivers, low vaccination coverage in children under 5 years of age and malnutrition in children that predisposes them to suffer all kinds of diseases. Methodology: The logical framework approach was followed, first a prioritization of problems and the analysis of those involved were carried out, the tree of problems and tree of objectives were outlined, then the solution alternatives were analyzed and the analytical structure of the project, then the logical framework matrix was made and finally the activities and tasks summarized in the programming matrix were proposed. Activities: Two main activities were carried out, which consisted of making posters and videos to present to the community online due to the current situation of the Sars-CoV-2 pandemic. Results: The results of the short-term project were measured by knowledge surveys answered by the community, one before the intervention and another after, the final achievement being the improvement of the community's knowledge in the prevention of respiratory diseases, recognition of its warning signs, the importance of vaccination, healthy eating, hygiene methods, breastfeeding, among others. / Tesis

This thesis investigates the possibilities of increasing efficacy and general improvement of unsupervised medical treatments by implementing electronics and embedded systems (so-called smart devices) to allow the physician to monitor or track the treatment and adherence of the patient to it. The diseases in focus are respiratory: asthma and Chronic Obstructive lung [Pulmonary] Disease (COPD). This thesis will furthermore attempt to show that shortcomings in the current treatment of these diseases incur significant human costs by loss of quality of life for the patients and causes (avoidable) costs to health-care systems and societies on a macro-economic scale, both direct and indirect. It will find that the technology to create a smart-inhaler exists, and while not a panacea, it can address many of the identified issues with the current mode of treatment.This thesis was written in partnership with SHL Medical AB, and the author wishes to extend specialthanks to Plamen Balkandjiev and Mattias Myrman for their help, support, and patience. / Detta examensarbete undersöker möjligheterna att öka effektiviteten samt allmänna förbättringar av oövervakad medicinsk behandling genom implementering av elektronik och inbyggda system (så kallade smarta-apparater) för att möjliggöra för läkare att övervaka eller följa behandlingen samt huruvida patienten fullföljer den eller ej. Sjukdomarna i fokus är astma och Kronisk Obstruktiv Lungsjukdom (KOL). Vidare kommer detta arbete försöka visa att tillkortakommanden i den befintliga behandlingen av sjukdomar inte bara medför signifikanta minskningar i livskvalitet för patienten utan även orsakar (icke oundvikliga) kostnader för sjukvårdssystem och samhällen på en makro-ekonomisk skala, indirekt såsom direkt. Den kommer även visa att tekniken som krävs för att skapa en smartinhalator existerar, och medans denna inte är en panacé kan den likväl åtgärda många av de identifierade problemen med den befintliga behandlingsmetoden.Detta exmanensarbete skrevs i samarbete med SHL Medical AB och dess författare önskar utsträckaett särskilt tack till Plamen Balkandjiev och Mattias Myrman för deras hjälp, stöd och tålamod.

Über die Ätiologie und Epidemiologie der Erkrankungen des Respirationstraktes im Frühneolithikum Mitteleuropas gibt es bislang keine umfassenden Studien. Die Häufigkeit, mögliche Geschlechts- und Altersunterschiede, Populationsunterschiede und Erkenntnisse über mögliche Ursachen und auslösende Faktoren der Atemwegserkrankungen zur Zeit der Bandkeramik sind von besonderem Interesse. Zudem soll aufgezeigt werden wie wichtig es ist, alle Strukturen zu untersuchen, die den „knöchernen Respirationstrakt“ repräsentieren. Von den ersten Ackerbauern und Viehzüchtern aus Wandersleben (Thüringen, Kreis Gotha) lagen insgesamt 112 erwachsene Individuen zur Untersuchung vor. Rippen und Schädel wurden mit paläopathologischen Methoden untersucht. Diese waren neben einer makroskopischen Begutachtung der Knochen, röntgenologische, endoskopische, lupenmikroskopische, lichtmikroskopische und rasterelektronenmikroskopische Untersuchungen, um eine verlässliche Diagnosestellung zu gewährleisten. 100 % (n = 71/71) der befundbaren Individuen zeigten Spuren chronischer Erkrankungen im Bereich der knöchernen Strukturen, die die oberen Atemwege umgeben. Bei 76,8% (n = 53/69) der Individuen mit befundbaren Rippen konnten Spuren von chronischen Erkrankungen aufgezeigt werden. Signifikante Geschlechts- oder Altersunterschiede bestehen insgesamt nicht. Bei der linearbandkeramischen Population aus Wandersleben ist davon auszugehen, dass es sich in vielen Fällen um Chronifizierungen von Erkältungskrankheiten und um die Folgen einer vergleichbar schlechten Luftqualität hauptsächlich im Haus handelt. Dazu haben die damaligen Lebensumstände, vor allem aber die sesshafte Lebensweise und Wirtschaftszweige mit Ackerbau und Viehzucht, maßgeblich beigetragen.
