Objective: Evaluation of surgical quality ensures consistency of care and facilitates improvements in the quality of care delivered. Methods: An overview of surgical quality measurement is presented. A system for monitoring thoracic morbidity and mortality (TM&M) at the Ottawa Hospital is introduced and evaluated. Results of a needs assessment survey on the involvement in thoracic surgical research and quality improvement initiatives are presented. Results: Structure, process, and outcomes reflect different viewpoints on how to evaluate surgical quality. The feasibility of the TM&M system is evaluated using descriptive and univariate statistics, while its inter-rater reliability is assessed amongst the Canadian Association of Thoracic Surgeons. Conclusions: Outcomes have been fundamental in the evaluation of surgical quality. TM&M classification system advocates for a practice of continuous quality improvement and provides standardized and reliable feedback on surgical outcomes. Results of the needs assessment have built a strong foundation of knowledge on prospective ways to enhance the monitoring of surgical quality.

A sua alta incidência tem relevante impacto nos óbitos, como também na sobrecarga do sistema de saúde e absenteísmo no trabalho e escola Todas as faixas etárias são acometidas, porém, as mais afetadas são as crianças e os idosos. Também são particularmente susceptíveis os imunocomprometidos e os portadores de doenças crônicas em geral. Os vírus são os agentes responsáveis pela maior parte das infecções respiratórias, os principais vírus causadores de infecções respiratórias são o influenza A e B e o Vírus Sincicial Respiratório (VSR). Estes vírus têm comportamento biológicos distintos e o conhecimento de como estes vírus afetam a saúde da população é fundamental para embasar as ações de prevenção, profilaxia e tratamento de pacientes permitindo uma alocação adequada de recursos em quantidade e tempo adequados. No Brasil, no ano 2000, para monitorar a ocorrência destes vírus foi implantada a vigilância de síndromes gripais SIVEP-GRIPE, que através de 128 unidades sentinelas distribuídas em todas as regiões do país coletam semanalmente amostras de secreção de nasofaringe por semana de pacientes com síndromes gripais. Neste trabalho estudamos o impacto do influenza na mortalidade no estado de São Paulo, nas diferentes faixas etárias no período entre 2002 e 2011, incluindo o período da pandemia de 2009. Estudamos também a sazonalidade do VSR nas 5 diferentes regiões brasileiras e o impacto deste vírus nas internações por doenças respiratórias entre menores de 5 anos. Metodologia: Para o estudo da mortalidade associada ao influenza utilizamos o método de regressão de Serfling adaptado para dados semanais extraindo da série histórica os períodos de maior circulação viral a partir dos resultados do sistema de vigilância sentinela SIVEP-GRIPE. Comparar a mortalidade associada à pandemia de influenza de 2009, às epidemias prévias anuais de influenza nas diferentes faixas etárias e com diferentes subtipos de vírus influenza circulantes no estado de São Paulo. Para o estudo da sazonalidade do VSR utilizamos análise de Wavelets, análise de Fourier, análise simplificada de estações anuais comparando os resultados nas 5 regiões administrativas do Brasil. Para identificar possíveis correlações temporais entre a circulação dos vírus respiratórios utilizamos métodos de regressão de ranque de Spearman e de regressão parcial. Resultados e conclusões: A mortalidade por pneumonia e influenza associada à pandemia de 2009 no estado de São Paulo foi ligeiramente mais alta que nos outros anos de influenza sazonal, considerando a mortalidade geral, sem distinção de faixa etária. Houve diferenças no risco de morrer entre as faixas etárias. Entre os indivíduos de 5 a 19 anos, a mortalidade associada à pandemia de 2009 foi 2,6 maior (0,6 óbitos/100.000hab) que a de anos não pandêmicos. Na faixa etária de 20 a 59 anos, a mortalidade associada à pandemia de 2009 foi 5,1 maior (2,8 óbitos/100.000hab) que nos anos não pandêmicos. As taxas de mortalidade entre menores de 5 anos foi 0,9 óbitos/100.000hab e na população de mais 60 anos foi 13,1 óbitos/100.000hab, ou seja, foram menores que nos anos não pandêmicos. O método de análise utilizado permitiu a diferenciação entre a mortalidade associada a subtipos virais (A(H3N2), B ou sazonal A(H1N1) e A(H1N1) pdm 2009). Foi possível a comparação entre a mortalidade associada à pandemia de influenza de 2009 em São Paulo, às epidemias anuais de influenza nas diferentes faixas etárias e com diferentes subtipos de vírus influenza circulando. Isto é, o impacto da circulação do vírus pandêmico influenza A(H1N1) foi maior na mortalidade em adultos e jovens, enquanto em maiores de 65 anos foi discreto. Por outro lado, o excesso de mortalidade foi expressivo em maiores de 65 anos, nos anos de circulação do influenza A(H3N2). O modelo de Serfling adaptado a dados semanais com validação por meio de dados da vigilância sentinela de síndromes gripais (SIVEP-GRIPE) mostrou-se confiável para detectar picos de maior circulação viral do Influenza e supostos reflexos na mortalidade em diferentes faixas etárias em período pandêmico, epidêmico e de circulação sazonal do vírus Influenza. Sobre o VSR foi possível identificar padrões sazonais do VSR em todas as regiões administrativas do Brasil utilizando-se dados da vigilância de síndromes gripais (SIVEP-GRIPE). Houve diferenças entre os momentos de maior circulação do vírus em algumas das cinco regiões administrativas do Brasil. Os padrões sazonais de internação por doenças sabidamente relacionadas com o VSR [Pneumonia devida a vírus respiratório sincicial, Bronquite aguda devida a vírus sincicial respiratório, Bronquiolite aguda devida a vírus sincicial respiratório, Bronquiolite (aguda, não especificada),] foram semelhantes aos encontrados pela análise da circulação do VSR por meio de dados da vigilância de síndromes gripais (SIVEP-GRIPE). Houve correlação temporal entre a circulação do VSR e as taxas de internação por doenças do aparelho respiratório em geral (Capítulo-X da CID-10) entre menores de 5 anos, nas cinco regiões administrativas do Brasil. Houve correlação temporal entre as taxas de internação entre menores de 5 anos por doenças sabidamente relacionadas com o VSR [Pneumonia devida a vírus respiratório sincicial, Bronquite aguda devida a vírus sincicial respiratório, Bronquiolite aguda devida a vírus sincicial respiratório, Bronquiolite (aguda, não especificada),] e as taxas de internação por doenças respiratórias em geral nesta faixa etária nas cinco regiões administrativas do Brasil, indicando que este é o principal vírus associado às internações de crianças até 5 anos por doenças respiratórias. De acordo com as evidências encontradas neste estudo, os esquemas de profilaxia contra o VSR hoje utilizados precisam ser revistos e particularizados para cada região do país. Entre as ações a serem revistas estão a disponibilização do palivizumabe, bem como medidas de prevenção à circulação do VSR na comunidade / Abstract: Introduction and Objectives: Respiratory infections are amongst the most important causes of morbidity and mortality worldwide. Its high incidence has significant impact on deaths, but also burdens the health system and leads to absenteeism from work and school All age groups are affected, but the most affected are children and the elderly. Are also particularly susceptible immunocompromised and patients with chronic diseases in general. Viruses are the agents responsible for most respiratory infections, the main cause of respiratory virus infections are influenza A and B and Respiratory Syncytial Virus (RSV). These viruses have distinct biological behavior and knowledge of how these viruses affect people's health is fundamental to support the prevention, prophylaxis and treatment of patients allowing an adequate allocation of resources in quantity and adequate time. In Brazil, in 2000, to monitor the occurrence of these viruses was established surveillance of influenza-like syndromes SIVEP-FLU, which through 128 sentinel units distributed in all regions of the country collect weekly samples of nasopharyngeal secretions of patients per week with influenza-like illness. In this work we study the impact of influenza on mortality in the state of São Paulo , in different age groups between 2002 and 2011 , including the period of the 2009 pandemic. We also studied the seasonality of RSV in 5 different Brazilian regions and the impact of this virus in hospitalizations for respiratory diseases among children under 5 years. Methods: To study the mortality associated with influenza used the regression method of Serfling adapted for extracting weekly data of the time series periods of increased viral movement from the results of sentinel surveillance system SIVEP - FLU . Compare the mortality associated with pandemic 2009 influenza , annual epidemics of influenza prior at different ages and with different subtypes of influenza viruses circulating in the state of São Paulo . To study the seasonality of RSV , we use wavelet analysis , Fourier analysis , simplified analysis of annual seasons comparing the results in five administrative regions of Brazil . To identify possible temporal correlations between the circulation of respiratory viruses use regression methods of Spearman rank and partial regression. Results and Conclusions: The mortality from pneumonia and influenza associated with the 2009 pandemic in the state of São Paulo was slightly higher than in the other years of seasonal influenza, considering the overall mortality, irrespective of age. There were differences in the risk of dying between age groups. Among individuals 5-19 years, the mortality rate associated with the 2009 pandemic was 2.6 higher than that of non-pandemic years. (0.6 deaths /100,000 inhabitants) In the age group 20-59 years, the rate associated with the 2009 pandemic mortality was 5.1 higher than in non-pandemic years. (2.8 deaths /100,000 inhabitants). Mortality rates among children under five years was 0.9 deaths /100,000 inhabitants and in persons over 60 years was 13.1 deaths /100,000 inhabitants, ie were lower than in non- pandemic years . The method of analysis used allowed the differentiation between mortality associated with viral subtypes (A(H3N2), A(H1N1) and B or seasonal A(H1N1) pdm 2009) . It was possible to compare the mortality associated with the 2009 influenza pandemic in Sao Paulo, annual influenza epidemics in different ages and with different subtypes of influenza viruses circulating. That is, the impact of the circulation of influenza A(H1N1) pandemic virus was higher mortality in adults and children, while in adults over 65 years was low . On the other hand, the excess mortality was significant in adults over 65 years ago, in circulating influenza A H3N2. The Serfling model adapted to weekly data validation using data from sentinel surveillance of influenza-like illness (SIVEP - GRIPE) was reliable for detecting peaks of higher viral circulation of influenza and alleged impacts on mortality in different age groups in pandemic period , epidemic and seasonal circulation of influenza viruses . About RSV was possible to identify seasonal patterns of RSV in all administrative regions of Brazil using surveillance data of influenza syndromes (SIVEP -GRIPE). There were differences between the moments of greatest circulation of the virus in some of the five administrative regions of Brazil. Seasonal patterns of hospitalization for known diseases with RSV [ Pneumonia due to respiratory syncytial virus , acute bronchitis due to respiratory syncytial virus , acute bronchiolitis due to respiratory syncytial virus bronchiolitis ( acute , unspecified ) ] were similar to those found by analysis of the movement of data through RSV surveillance of influenza-like syndromes ( SIVEP - GRIPE) . There was a temporal correlation between the circulation of RSV and the rates of hospitalization for respiratory diseases in general (Chapter X of ICD- 10) among children under 5 diseases in the five administrative regions of Brazil . There was a temporal correlation between the rates of hospitalization among children under 5 years for known diseases with RSV [ Pneumonia due to respiratory syncytial virus , acute bronchitis due to respiratory syncytial virus , acute bronchiolitis due to respiratory syncytial virus bronchiolitis ( acute , unspecified ) ] and rates of hospitalization for respiratory diseases in general in this age group in the five administrative regions of Brazil , indicating that this is the main virus associated with hospitalizations of children under 5 years due to respiratory diseases . According to the evidence found in this study , the schemes of prophylaxis against RSV used today need to be reviewed and individualized for each region of the country . Among the actions to be reviewed are the availability of palivizumab , as well as measures to prevent the circulation of RSV in the community / Doutorado / Epidemiologia / Doutor em Saude Coletiva

The Cooperative Extension System has focused on nutrition education for low-income families for approximately 29 years via the Expanded Food and Nutrition Education Program (EFNEP). In response to the need for a comprehensive economic evaluation of EFNEP, Virginia Cooperative Extension (VCE) was awarded a grant from the Cooperative State Research, Education and Extension Services, United States Department of Agriculture (CSREES, USDA) to conduct a cost benefit analysis (CBA) of nutrition education programs, with emphasis on EFNEP. Virginia EFNEP served as the pilot program to test the evaluation procedure. This study is a part of the CBA of Virginia EFNEP. The purpose is to calculate the indirect tangible benefits derived from participation in EFNEP. The indirect tangible benefits are classified as 1) delaying productivity loss due to mortality and 2) avoiding productivity loss due to morbidity. This study also uses sensitivity analysis to evaluate the effects of two critical assumptions pertaining to retention of dietary behaviors and to incidence rate of diseases in the low-income population. Finally, the discount rate is analyzed via sensitivity calculations. There were two major conclusions drawn from this study. First, the indirect benefits accounted for more than $1 million of the total benefit generate by EFNEP. Second, the sensitivity analyses support the positive outcome (i. e., positive return on every dollar invested) derived from the CBA of Virginia EFNEP. / Master of Science

Hypertension is not consistently associated with postoperative cardiovascular morbidity and therefore not considered a major peri-operative risk factor. However, hypertension may predispose to peri-operative haemodynamic changes known to be associated with perioperative morbidity and mortality, such as intra-operative hypotension and tachycardia. The objective of this study was to determine whether pre-operative hypertension was independently associated with haemodynamic changes known to be associated with adverse peri-operative outcomes. We performed a five-day multicentre, prospective, observational cohort study which included all adult inpatients undergoing elective, noncardiac, non-obstetric surgery. We recruited 343 patients of whom 164 (47.8%) were hypertensive. An intra-operative mean arterial pressure of 100 beats per minute) occurred in 126 (38.9%) patients, of which 61 (48.4%) were hypertensive. Multivariable logistic regression did not show an independent association between the stage of hypertension and either clinically significant hypotension or tachycardia, when controlled for ASA physical status, functional status, major surgery, the duration of surgery or blood transfusion. There was no association between pre-operative hypertension and peri-operative haemodynamic changes known to be associated with major morbidity and mortality. These data therefore support the recommendation of the Joint Guidelines of the Association of Anaesthetists of Great Britain and Ireland (AAGBI) and the British Hypertension Society to proceed with elective surgery if a patient’s blood pressure is < 180/110 mmHg.

Magister Public Health - MPH / In 2018 Opuwo Maternity Waiting Home (MWH) was inaugurated after its completion with the assistance from WHO and the European Union. This initiative by the Ministry of Health and Social Service and its partners was aimed to ensure safe deliveries as well as to overcome physical and socio-economic barriers such as long distances, communication and high transport costs to access health care facilities for safe deliveries in Opuwo District. However, since its inception the facility has been under-utilized. The aim of the study was to explore male partners’ experiences, perceptions and roles regarding the use of the MWH in Opuwo District, Namibia.

Rationale. Alcohol use disorders (AUDs) and tobacco dependence are frequently identified as co-morbid. Although less than 20% of the general population smokes, over 80% of people with AUDs are considered daily smokers. In fact, people with AUDs are more likely to die from smoking-related health issues, than from alcohol related health issues. Surprisingly, there is very little evidence that alcohol and nicotine are concurrently self-administered in pre-clinical models. We hypothesized that low doses of nicotine that enhancing responding for other rewards would be self-administered and enhance self-administration of alcohol. Objective. The goal of this study was to determine if low-doses of nicotine, typically not self-administered alone, would promote alcohol self-administration in a concurrent access paradigm. Method. Alcohol preferring rats (females) were requested from the University of Indiana Medical School breeding facility. They were randomly assigned to one of three groups – NIC-Alone, ALC-Alone, or ALC+NIC. All rats were fluid restricted and shaped to lick for water at two sipper tubes that could record lick responses and deliver aliquiots of fluid into the sipper tube via a solenoid valve. After shaping, rats were instrumented for IV self-administration. During self-administration tests, rats in the ALC-Alone received access to oral ethanol (15% v/v) for meeting the schedule of reinforcement at one sipper tube (e.g., right) and saline infusions for meeting the schedule of reinforcement at the other sipper tube (e.g., left). The NIC-Alone group received IV nicotine infusions (15 ug/kg/inf) and oral licorice (1%) for meeting the schedule of reinforcement at one sipper tube (e.g., left) and oral water for meeting the schedule of reinforcement at the other sipper tube (e.g., right). The ALC+NIC group received IV nicotine and oral licorice for meeting the schedule of reinforcement on the left sipper, and oral ethanol for meeting the schedule of reinforcement on the right sipper. Price manipulations for nicotine were performed by adjusting the schedule of reinforcement on the sipper associated with nicotine infusions. Results. During acquisition, nicotine did not enhance alcohol self-administration – alcohol intake was comparable between ALC-Alone and ALC+NIC rats. In addition, alcohol did not enhance nicotine self-administration as responding for NIC was comparable between ALC+NIC and NIC-Alone rats. However, when the price of nicotine was manipulated, alcohol created a greater demand for nicotine, as indicated by higher rates of nicotine consumption with increases in price. Manipulating the price of nicotine did not alter demand for alcohol. Conclusion. The interaction between alcohol and nicotine reinforcers may depend on changes in demand for nicotine. Future studies should investigate whether demand for alcohol is altered by concurrently available nicotine infusions. *the first and second authors contributed equally to this project
