研究背景：顆性空氣污染物（PM₁₀）的危害作用已經為許多病學研究所證實。有學者認為，空氣動學直徑小於2.5 微米的細顆（PM₂.₅）和空氣動學直徑介於2.5 和10 微米之間的粗顆（PMc）屬於種同的污染物，應當分別測。區分粗、細顆的健康效應將為今後分別制訂有關粗、細顆的空氣質標準提供依據。同時，空氣污染物是由顆污染物和氣態污染物構成的複雜混合物，二者之間存在一定程上的合或交互作用。 / 研究目的：以每天心血管系統、呼吸系統疾病急性入院人為研究結局，區別估計顆污染物PM₁₀ 中粗、細顆的健康危害作用，并探討PM₁₀與氣態污染物（二氧化氮，NO₂；二氧化，SO₂；臭氧，O₃）的交互作用。 / 研究方法：收集香港1998 1 月至2007 12 月每天心腦血管疾病、呼吸系統疾病急性入院人，日均污染物濃，日均氣溫、相對濕等資，採用時間序分析的研究方法，應用Poisson 廣義相加模型分析顆污染物中粗、細顆的同健康效應。同時應用三個平的時間序研究模型（雙變反應面模型、合效應模型和分層模型）探討顆污染物和氣態污染物之間潛在的交互作用。 / 研究結果：研究發現，在校正PM₂.₅的影響后，PMc 對呼吸系統疾病導致的急性入院作用顯著，但對心腦血管疾病引起的急性入院則無明顯作用。在雙污染物（PMc 和PM₂.₅）模型中，空氣中每一個IQR（四分位間距）的PM[subscript c] 和PM₂.₅濃的增加將使每天急性呼吸系統疾病入院分別增加1.05% (95% CI: 0.19%, 1.91%)和1.81% (95% CI: 0.78%,2.87%)，使急性心腦血管疾病入院分別改變 -0.16% (95% CI: -1.07%,0.76%) 和1.86% (95% CI: 0.85%, 2.88%)。研究發現某種程6 的顆污染物和氣態污染物的交互作用。在NO₂ 或SO₂ 高水平（NO₂ 濃高於64.4μg/m³ 或 SO₂ 濃高於20.9μg/m³）的日子，PM₁₀ 對急性心臟疾病入院的影響高於NO₂ 或SO₂ 低、中水平的日子；而在臭氧高水平（O₃濃高於46.8μg/m³）的日子，PM₁₀ 對急性呼吸和循環系統疾病入院的作用低於O₃ 中、低水平的日子。 / 研究結：粗、細顆污染物對呼吸系統疾病的危害均作用顯著且相對獨，但對循環系統疾病的危害作用則主要體現於細顆污染物。同時，顆性污染物的健康危害可能被空氣中的氣態污染物水平所修飾：研究發現PM₁₀ 與NO₂ 或SO₂ 之間的協同作用，以及PM₁₀ 與O₃ 之間的拮抗作用。 / BACKGROUND: The adverse effects of particulate matter (PM) air pollution have been confirmed by many epidemiological studies. Fine and coarse particles should be considered as separate classes of pollutants and measured separately. Differentiating the effects of fine (PM₂.₅, particles with an aerodynamic diameter less than 2.5 microns) and coarse particles (PM[subscript c], particles with an aerodynamic diameter between 2.5 and 10 microns) would help in the future to support a PM[subscript c] standard. Meanwhile, ambient air pollution is a complex mixture of PM and gaseous pollutants. PM might interact with gaseous pollutants to affect the population health. / STUDY OBJECTIVES: To differentiate the effects of fine and coarse fractions of PM₁₀ and to explore the possible interaction between PM₁₀ and gaseous pollutants (nitrogen dioxide, NO₂; sulfur dioxide, SO₂; ozone, O₃) on emergency hospital admissions for cardio-respiratory diseases in Hong Kong. / METHODS: This is a time series study. Daily counts of emergency hospital admissions for cardio-respiratory diseases, daily mean air pollution concentrations and weather conditions were collected from January 1998 to December 2007 in Hong Kong. We used generalized additive Poisson model with log link allowing overdispersion and autocorrelation to examine the differential effects of PM₂.₅ and PM[subscript c]. Three parallel time series approaches (bivariate response surface model, joint effect model and parametric stratified model) were used to explore the possible interactions between PM₁₀ and gaseous pollutants. / MAIN RESULTS: The associations between PM[subscript c] and emergency hospital admissions were statistically significant for respiratory diseases but not for circulatory diseases. In two-pollutant (PM₂.₅and PM[subscript c]) model, an interquartile range increase in the 4-day moving average (lag₀₃) concentrations of PM[subscript c] and PM₂.₅ corresponded to 1.05% (95% CI: 0.19%, 1.91%) and 1.81% (95% CI: 0.76%, 2.87%) increase of respiratory admissions, respectively. The effect estimates of PM₂.₅and PM[subscript c] remained robust when adjusting for gaseous pollutants. Meanwhile, an interquartile range increase in lag₀₁ concentrations of PM[subscript c] and PM₂.₅was associated with -0.16% (95% CI: -1.07%, 0.76%) and 1.86% (95% CI: 0.85%, 2.88%) change of circulatory admissions, respectively. Some interactions between PM₁₀ and gaseous pollutants were found. The effects of PM₁₀ on circulatory hospitalizations were greatest during the days when NO₂ or SO₂ concentrations were high (the 3rd tertile, NO₂>64.4 or SO₂>20.9μg/m³). The effects of PM₁₀ on both respiratory and circulatory admissions were greatest during the days when O₃ concentrations were in low to medium levels (<=46.8μg/m³). / CONCLUSION: We found PM[subscript c] to be associated with emergency hospital admissions for respiratory diseases independent of the effect of PM₂.₅, but not for circulatory diseases in Hong Kong. The effects of PM₁₀ on cardio-respiratory hospital admissions were modified by gaseous pollutants. There were synergetic interactions between PM₁₀ and NO₂ or SO₂ on cardiac hospitalizations and antagonistic interactions between PM₁₀ and ozone on cardio-respiratory hospitalizations. These findings provide supportive evidence for a future PM[subscript c] regulation and contribute to the development of a multipollutant air quality management. / Detailed summary in vernacular field only. / Detailed summary in vernacular field only. / Detailed summary in vernacular field only. / Detailed summary in vernacular field only. / Detailed summary in vernacular field only. / Qiu, Hong = 顆粒污染物對人群健康的短期效應 : 時間序列研究 / 邱宏. / Thesis (Ph.D.)--Chinese University of Hong Kong, 2012. / Includes bibliographical references (leaves 122-137). / Electronic reproduction.

O preparo e a administração de medicamentos são práticas realizadas no cotidiano pela equipe de enfermagem. Para que haja segurança aos pacientes na utilização dos medicamentos, faz-se necessário que os profissionais envolvidos no sistema de medicação tenham o conhecimento e o entendimento do conceito de erro na medicação de maneira clara, para que possam identificar o erro bem como as situações facilitadoras para sua ocorrência. O presente estudo teve como objetivo analisar o conhecimento dos auxiliares de enfermagem de um hospital de ensino sobre o conceito de erro na medicação antes e após a implantação de uma oficina de capacitação. A pesquisa foi realizada em um hospital universitário situado na Região Noroeste do Estado do Paraná. A amostra foi constituída de 47 auxiliares de enfermagem que estavam regularmente matriculados no curso de formação profissionalizante em técnico de enfermagem e que exerciam a atividade assistencial, tendo a medicação como rotina em sua prática. A pesquisa foi aprovada pelo comitê de ética em pesquisa de uma universidade estadual, em conformidade com a Resolução n.º 196/96. Trata-se de um estudo quantitativo com delineamento quase-experimental, tendo como referencial teórico a abordagem sistêmica do erro. A coleta dos dados ocorreu em três etapas: 1. pré-teste, 2. desenvolvimento de uma oficina dinâmica de estudos fundamentada na metodologia da problematização, e 3. pós-teste. Os resultados foram agrupados em sete categorias, as quais seguem: 1. comunicação entre a equipe de saúde; 2. cumprimento do horário da administração de medicamentos; 3. execução do procedimento técnico; 4. dispensação e distribuição dos medicamentos; 5. sistemas de medicação; 6. administração de medicamentos propriamente dita e 7. complicações relacionadas aos medicamentos. Os resultados apontaram que os participantes não perceberam o atraso na administração de medicamentos e a falta de monitoramento pós-administração como erro na medicação, demonstrando uma confiança na regra dos cinco certos e pouco conhecimento dos protocolos de preparo e conservação dos fármacos. Constatou-se a existência de situações facilitadoras para a ocorrência de erro no sistema de medicação, destacando-se que o processo de seleção e prescrição tem maior risco de promover um erro e o processo de dispensação e distribuição possui menor possibilidade em desencadear erro na medicação. / The preparation and administration of medication are daily practices carried out by the nursing team. In order to grant safety to patients in medication use, it becomes necessary for professionals involved in the medication system to possess clear knowledge and understanding about the concept of medication error for them to be able to identify the error, as well as the situations that facilitate its occurrence. This study aimed to analyze the knowledge of nursing auxiliaries at a school hospital with respect to the medication error concept before and after the implantation of a training workshop. The research was carried out at a university hospital located in the northwestern region of Paraná, Brazil. The sample consisted of 47 nursing auxiliaries, who were regularly enrolled in a nursing technician professional formation course and active in nursing care, so that medication was part of their routine practice. The research project was approved by the Research Ethics Committee in accordance with Resolution nº 196/96 - CNS. This is a quantitative and exploratory study with quasi-experimental outlines, adopting the systemic error approach as a reference framework. Data collection involved three phases: 1. pre-test, 2. development of a dynamic study workshop based on problem methodology, and 3. post-test. Results were grouped into seven categories as follows: 1. communication among health team members; 2. accomplishment of medication administration time; 3. technical procedure realization; 4. medication dispensation and distribution; 5. medication systems; 6. medication administration in itself and 7. complications related to medication. We highlighted that, according to the results, the participants did not perceive the delay in medication administration and the lack of post-administration monitoring as a medication error, demonstrating excessive trust in the five rights and little knowledge about the preparation and conservation protocols for pharmaceutical products. We observed the existence of situations that facilitate the occurrence of errors in the medication system, emphasizing that the selection and prescription process contains greater risk of leading to error and that a smaller possibility of medication error is contained in the dispensation and distribution process.

SAMMANFATTNING Bakgrund: Enligt Regionala Cancercentrums nationella vårdplan för cancerrehabilitering rekommenderas alla patienter med cancerdiagnos att försöka röra på sig lika mycket som en frisk människa rekommenderas. Trots detta så händer det att personer med cancerdiagnos minskar sin träning. Därför är det viktigt att få en fördjupad förståelse av hur dessa patienter upplever träning under sin behandling. Syfte: Beskriva hur cancerpatienter upplever träning under pågående behandling samt vilka faktorer som påverkar patienternas träning (egenvård) under pågående behandling. Metod: Kvalitativ intervjustudie. Elva intervjuer från en pilotstudie i Phys-Can projektet analyserades med hjälp av en kvalitativ innehållsanalys. Resultat: Stöd från professionella, personer i en likartad situation, anhöriga samt stöd från sig själv upplever deltagarna varit viktiga för att kunna utföra träningen. Praktiska faktorer som tid till träning, möjligheten att ta sig till träningen samt lokalen upplever deltagarna påverka hur träningen uppfattas. Deltagarna har upplevt att träningen påverkar psykiska och fysiska faktorer hos dem mestadels till det positiva. Träningen har även påverkat några av deltagarnas upplevelse av deras sjukdom. Slutsats: Deltagarna i denna studie har upplevt att stöd i olika former har varit viktigt för att kunna utföra träningen som egenvård. De praktiska förhållandena runt träningen har upplevts kunna både försvåra eller förenkla träningen. Deltagarna har även upplevt att träningen har påverkat deras psykiska och fysiska hälsa oftast till det positiva. Det är av vikt att kunna se varje individs förutsättningar att kunna utföra egenvården och sedan anpassa stödet så att träningsförutsättningarna blir så bra som möjligt. / ABSTRACT Background: According to the Regional Cancer Centre's national treatment plan for cancer rehabilitation all patients with a cancer diagnosis are recommended to try to move as much as a healthy person. Even so it happens that people with cancer reduces their physical activity. Therefore, it is important to get a deeper understanding of how these patients experience training during their treatment. Aim: Describe how cancer patients experience exercise during treatment and the factors that affect patients’ exercise (self-care) during treatment. Method: A qualitative interview study. Eleven interviews from a pilot study in the Phys-Can project were analyzed using qualitative content analysis. Result: Support from professionals, people in a similar situation, relatives and support from her/himself participants experienced as important to carry out their training. Practical factors as time to exercise, the ability to get to the training venue and how they experienced the venue the participants affected how their training was perceived. The participants have experienced that exercise affects mental and physical factors in them mostly for the better. The traning has also affectes som of the participants’ experince of their disease. Conclusion: The participants in this study have experienced various forms of support that has been experienced as important to be able to perform the exercise as self-care. The practical conditions around the training could both complicate or simplify training. Participants also felt that the training has affected their mental and physical health, usually for the better. It is important to be able to see each individual's ability to perform self-care, and then align support so that exercise becomes as good as possible.
