This thesis is based on the use of mathematical theories, modelling, and simulations to study the transmission dynamics of HIV/AIDS in the presence of PrEP (pre-exposure prophylaxis) in the MSM (men who have sex with men) population in the United States. A new deterministic model for HIV/AIDS that incorporates PrEP is designed and used to assess the population-level impact of the use of PrEP on the transmission dynamics within an MSM population. Conditions for the effective control (or elimination) and persistence of HIV/AIDS in the MSM population are determined by rigorously analyzing this model. Uncertainty and sensitivity analysis is carried out to determine the effect of the uncertainties in the parameter values on the response variable (the associated reproduction number) and to identify the top-five parameters that have the most effect on the disease transmission dynamics. Numerical simulations show that HIV burden decreases with increasing PrEP coverage. / October 2015

Blacks are more affected by Human Immunodeficiency Virus (HIV)/Acquired Immunodeficiency Syndrome (AIDS) than any other race or ethnicity in the United States. The purpose of this dissertation was to investigate potential race-based differences in cardiovascular disease (CVD)-related hospitalizations and use of opportunistic infection (OI) prophylaxis between Blacks and Whites with HIV/AIDS. This dissertation includes two systematic literature reviews that identified knowledge gaps in the areas of CVD diagnosis and OI prophylaxis use between Blacks and Whites with HIV/AIDS, as well as two independent studies that addressed some of the gaps identified in the literature. The first study evaluated the association between race and CVD-related hospitalization in Blacks and Whites with HIV/AIDS. Data were retrieved from the 1996-2008 National Hospital Discharge Surveys (NHDS). Approximately 1.5 million hospital discharges were identified. After controlling for confounders, the odds of CVD-related hospitalization were 45% higher for Blacks than Whites (OR=1.45, 95% CI, 1.39-1.51). There was a statistically significant difference in the proportions of CVD-related hospitalization type and race (x2=479.77; df=3; p<0.001). Compared to Whites with HIV/AIDS, Blacks with HIV/AIDS had greater proportions of heart failure and hypertension, but lower proportions of stroke and coronary heart disease. These results suggest that there is an influence of race on both the occurrence and type of CVD-related hospitalizations in patients with HIV/AIDS. The second study assessed if race was associated with the use of OI prophylaxis (Pneumocystis jiroveci pneumonia [PCP] and Mycobacterium avium complex [MAC]). Data for this study were retrieved from the 1996-2008 National Hospital Ambulatory Medical Care Surveys (NHAMCS). Approximately 9.1 million hospital ambulatory visits were identified. After controlling for confounders, the odds of PCP prophylaxis use were 16% higher for Blacks than for Whites (OR=1.16, 95% CI, 1.15-1.17). In a separate regression analysis, the odds of MAC prophylaxis use were 12% higher for Blacks than for Whites (OR=1.12, 95% CI, 1.10-1.13). These findings suggest that Blacks with HIV/AIDS may have increased odds for OI prophylaxis. Based on this work, there is a need for further research to confirm these findings and to identify the causes of these race-based disparities. / text

Lietuva saugaus eismo požiūriu yra padidintos rizikos šalis, todėl avaringumas yra vienas iš pagrindinių rodiklių, atspindinčių transporto sistemoje vykstančius procesus, jų teigiamą ar neigiamą raidą. Pagrindiniai statistiniai avaringumo rodikliai (informacija apie eismo įvykius, žuvusiuosius ir sužeistuosius) neigiamai apibūdina saugaus eismo situaciją šalyje. Šalyje iki šiol pasigendama racionalios saugaus eismo sistemos struktūros, kuri užtikrintų visų grandžių veiklos nuoseklumą bei tarpusavio sąveiką. Eismo priežiūra ir kontrolė - epizodiškos, todėl vis dažniau vairuojama apsvaigus nuo alkoholio ar narkotinių medžiagų, vis mažiau vairuotojų ir keleivių naudojasi saugos diržais, vaikai vežami ne specialiose saugos kėdutėse, dažnai viršijamas greitis. Nors eismo įvykiai yra atsitiktiniai, tačiau būtina suvokti ir valdyti jų priežastis, aplinkybes ir padarinius, kad būtų užkirstas jiems kelias arba bent sušvelninti padariniai. Todėl šio tyrimo tikslas - atskleisti kriminalistinės profilaktikos priemonių galimybes daryti įtaką eismo įvykių mažėjimui keliuose bei ištirti jų poveikį eismo saugumui. Siekiant iškelto tikslo formuluojami šie uždaviniai: 5. atskleisti kriminalistinės profilaktikos sampratą; 6. atlikti eismo įvykių kriminalistinės charakteristikos analizę; 7. išanalizuoti eismo įvykių tyrimo ir prevencijos praktiką Kauno apskrities policijos komisariatuose; 8. tiriant labiausiai paplitusias eismo įvykių kilimo priežastis numatyti eismo įvykių kriminalistinės...

The main statistical indicators of traffic accsidents (information about traffic accsidents, died or injured people) there negative discribing the situation in Lithuania. There no rational safety traffic system in Lithuania. The traffic observation and control are episodical and there more drunk driving accsidents in Lithuania. The drivers do not using safety belts, children safety chairs, they are over speeding. We know that traffic accsidents are accidental but we must realize and control the causality, circumstances and after-effects. The purpose of this analysis is reveal the criminology prophylaxis of the traffic safety and how to influence in down-sizing in traffic accsidents. The main tasks of the analysis: 1. The conception of the criminalistics prophylaxis. 2. To make the analysis of the traffic accsidents characterization. 3. Analyse the investigation and prevention of the traffic accsidents in Kaunas police commissariats. 4. Investigate the most common traffic accsidents reasons, the criminalistics prophylaxis and how to improve.

SUMMARY Aim of the study. To evaluate the possibilities of control of the children tuberculosis in Kaunas County. Objectives. 1. To evaluate the epidemiological situation of the children tuberculosis in Kaunas County in 1996 – 2003. 2. To evaluate the problems of early diagnostics and treatment of the children tuberculosis. 3. To propose the possible means of control of the children tuberculosis. Methods. Study objects were the patients with active tuberculosis treated in the Department of Children Pulmonology of Kaunas II hospital during 1996–2003 and general practitioners (GP) working in Primary Health Care Centers (PHCC). All the files of 538 patients treated with active tuberculosis during the analyzed period and 199 questionnaires answered by GP were analyzed. 79% of children treated were from Kaunas County. The statistical analysis was done with SPSS software for data acquisition and analysis. Results. The contact with adult persons with TM positive tuberculosis was the main factor defining children tuberculosis (TB) cases (45,0%). The number of children treated with TM positive tuberculosis increased from 2,0% to 13,1% (p <0,001) during 1998–2003. Only 64,3% of GP in their PHCC had the possibility to make tuberculin skin test (TST) and X-rays of the chest. The diagnosis of TB was verified during the prophylactic check up in 74,2% of cases in 2000, this number decreased to 27,5% (p <0,001) due to the disturbed supply of tuberculin in 2001. Only 26,1% of GP got the... [to full text]

Orientadora: Adolorata Aparecida Bianco Carvalho / Coorientador: Antonio Sergio Ferraudo / Banca: Angela Cleusa de Fátima Banzatto de Carvalho / Banca: Sonia Regina Pinheiro / Resumo: Um elevado número de tratamentos anti-rábicos profiláticos são efetuados, anualmente, em pessoas envolvidas em agravos com animais. Assim, este trabalho objetivou avaliar os registros e a conduta de profilaxia anti-rábica humana no Município de Jaboticabal, de 2000 a 2006, analisando as informações das fichas de atendimento e a distribuição geográfica dos agravos. Os dados foram tabulados em Excel e analisados com softwares EpiInfo e MapInfo. Também foi calculado o custo direto com as vacinas anti-rábicas humanas. Em 3056 fichas analisadas, computou-se um agravo para cada 160 habitantes, com maior ocorrência em residências e nos bairros da região central da cidade, e incremento de casos nos meses de janeiro, julho, agosto e dezembro. A faixa etária mais atingida foi de 0 a 15 anos, destacando-se o sexo masculino. Com relação à espécie animal envolvida, a canina foi a responsável pela maioria dos agravos, sendo 67,5% dos cães e 22,2% dos gatos declarados vacinados; os cães estavam sadios em 77,8% dos casos. Das pessoas agredidas, 81,6% receberam profilaxia pós-exposição, num total de 7.108 doses de vacina e a um custo aproximado de R$179.105,14. A análise detalhada dos dados, aliada ao fato de Jaboticabal ser considerada região controlada para a raiva, permitem questionar que 1.720 pessoas podem ter recebido vacina sem necessidade. Uma maior atenção deve ser dispensada aos registros de atendimento a agravos por animais, e uma análise acurada e mais criteriosa destes deve ser feita para que os tratamentos sejam instituídos adequadamente. Como a maioria dos acidentes ocorre em residências, portanto com cães e gatos domiciliados e vacinados, recomendam-se programas educativos para promoverem a posse responsável e o conhecimento dos cuidados que as pessoas devem ter com seus animais de estimação. / Abstract: A large number of rabies post-exposure treatment is annually given to humans attacked by animals. This study was aimed to evaluate the records and the conduct of rabies prophylaxis in humans, in the municipality of Jaboticabal, from 2000 to 2006, through the analysis of patients' records and geographic distribution of the accidents. The data were arranged in Excel® spreadsheets and were further analysed by EpiInfo® and MapInfo®. Also, the direct costs of given vaccines were calculated. From 3,056 patient's cards, it was observed 1 animal attack per 160 inhabitants, with higher occurence in residences, central neighborhoods and concentration of attacks in the months of January, July, August and December. The most affected age group was that of 0-15 years old, with predominance in males. As to animal species, dogs were responsible for causing the majority of accidents. 67.5% of dogs and 22.2% of cats had already been vaccinated before attacking. In 77.8% of occurences, the dogs were healthy. As to attacked humans, 81.6% of them received post-exposure prophylaxis, totalizing 7,108 antirabies vaccine doses at an approximate cost of R$179.105,14. Thorough data analysis and the fact that Jaboticabal lies in a rabies controlled region allow to question the administration of post-exposure vaccination in 1,720 persons. More attention should be payed to filling out and interpreting patient's records correctly, so that treatments can be properly established. As most attacks happen in the residences, where cats and dogs are usually domiciled and vaccinated, it is essencial to develop educational programs that promote responsible pet ownership and adequate pet handling and care. / Mestre

Objetivo: comparar a profilaxia universal com a terapia preemptiva com ganciclovir endovenoso no manejo da citomegalovirose em pacientes transplantados de pulmão em uma coorte retrospectiva. Metodologia: de março de 1999 a dezembro de 2009 foram estudados, no Serviço de Transplante do Complexo Hospitalar Santa Casa de Porto Alegre, todos os pacientes submetidos a transplante pulmonar, procurando-se verificar a ocorrência de citomegalovirose relacionada ao tipo de tratamento profilático anti-viral utilizado (universal e preemptiva). Foram excluídos, em ambos os grupos, os pacientes nos quais não tivesse sido registrada a antigenemia no primeiro mês após o transplante, e os que foram a óbito dentro dos primeiros trinta dias após a cirurgia. Resultados: de 224 pacientes transplantados no período referido, 66 (29,5%) foram excluídos por óbito precoce. Os 158 pacientes que entraram no estudo tinham idade de 51±15 anos (7 anoa-71 anos), e 61,0% eram do sexo masculino; 150 (95%) receberam o órgão de doador cadavérico, e 134 (85,0%) foram submetidos a transplante unilateral. A profilaxia universal para citomegalovirus (CMV) foi realizada em 70 pacientes (44,0%) e a terapia preemptiva em 88 (56,0%). O grupo que recebeu profilaxia universal levou maior tempo para positivar o exame (p<0.001) comparado com o grupo que não a recebeu. Houve associação significativa entre profilaxia e antigenemia positiva no primeiro ano após o transplante (p=0.024). A mortalidade no primeiro e no quinto ano foi respectivamente de 20% e 50%. A sobrevida mediana do grupo com profilaxia universal foi 3.8 anos (IC95% de 2.5 a 5.0) e o grupo com terapia preemptiva de 4,3 anos (IC95% de 2.5 a 6.0), não apresentando diferença significativa. Conclusão: com base nos dados obtidos neste estudo a profilaxia universal e a terapia preemptiva demonstraram-se seguras e efetivas, entretanto os achados desta pesquisa não se demonstraram conclusivos para definir a melhor opção terapêutica. / Objective: To compare the universal prophylaxis and preemptive therapy for the treatment of cytomegalovirus in lung transplant patients in a retrospective cohort. Method: Performed at the Lung Transplant service in Santa Casa de Porto Alegre during the period from March 1999 to December 2009, upon reviewing the records and results of cytomegalovirus detection. Were excluded in both groups the patients who were not registered antigenemia in the first month after lung transplantation, due to death during this period. Results: 224 patients transplanted during the study period, 66 patients were excluded due to death within 30 days after transplantation. Mean age of patients was 51 ± 15 years old, 61.0% were men, 95.0% received organ of cadaveric donors, 85.0% were submited to unilateral transplant. The universal prophylaxis was performed in 44.0% of patients and preemptive therapy in 56.0%. The group receiving prophylaxis universal took longer to make positive antigenemia (p <0.001) when compared with the group not receiving prophylaxis. It was observed significant association between positive antigenemia and prophylaxis in the first year after transplantation (p = 0.024). The general mortality in the first and fifth year was 20.0% and 50.0% respectively. Survival of patients with prophylaxis presented a median of 3.8 (95% CI 2,5 to 5.0) years and the group that received no prophylaxis had a survival of 4,3 years (95% CI 2.5 to 6.0). Conclusion: Based on the data obtained in this study universal prophylaxis and preemptive therapy demonstrated to be safe and effective, however the findings of this research did not prove conclusive to determine the best treatment.

Orientador: Hugo Hyung Bok Yoo / Resumo: Introdução: O Tromboembolismo Venoso (TEV) inclui a trombose venosa profunda (TVP) e a tromboembolia pulmonar (TEP), que são doenças com causa de óbito hospitalar evitável mais comum, principalmente em pacientes críticos sejam eles cirúrgicos ou clínicos. Objetivo: Analisar o nível de profilaxia de TEV em pacientes na Unidade de Terapia Intensiva (UTI) por afecções clínicas e cirúrgicas. Verificar fatores clínicos associados ao desenvolvimento de TEV na UTI e diminuir a escassez de estudos na literatura que avaliem as práticas de profilaxia de TEV em UTI no Brasil. Métodos: estudo transversal observacional de caráter descritivo realizado através de análise de prontuários eletrônicos. Participaram pacientes internados na UTI durante o período de março de 2016 a março de 2017 e tiveram seus riscos de tromboembolismo venoso estratificado segundo a 9ª Diretriz para Profilaxia do TEV do American College of Chest Physicians (ACCP). A adequação da tromboprofilaxia foi determinada de acordo com a concordância entre a conduta instituída e a conduta preconizada nas diretrizes. Resultados: Dos 182 pacientes analisados, 60% foram do sexo feminino. A idade média foi de 61,8 ± 18,0 anos, sendo 77% dos pacientes com idade maior que 50 anos. A idade média dos pacientes cirúrgicos foi significativamente maior em relação aos clínicos e dos pacientes do estudo (p=0,046), assim como tempo de internação hospitalar (p= 0,005) e na UTI (p= 0,010) também foi significativamente maior nos cirúrgicos. ...
