Introdução: A bexiga é responsável em armazenar urina em volume adequado e de esvaziar seu conteúdo de forma plena. Suas propriedades miogênicas intrínsecas e viscoelásticas são as responsáveis por esta função. Disfunções vesicais podem ser decorrentes, dentre outras causas, de anormalidades intrínsecas da musculatura detrusora ou da composição de sua matriz extracelular (MEC). O colágeno corresponde a 50% do estroma vesical, possuindo importante papel na adaptação vesical a condições fisiopatológicas específicas. Os colágenos tipo I e III são os mais comuns, sendo o colágeno tipo III o primeiro a ser sintetizado em processos de reparação e fibrose. Diversas afecções como a obstrução infravesical (OIV) parcial crônica podem induzir estes processos através da remodelação da MEC e conseqüentemente alterar a função vesical. Acredita-se que a hipercolesterolemia também o faça, porém ainda não foi reproduzida tal associação a nível morfológico. O objetivo deste estudo é avaliar se dieta hipercolesterolêmica promove alterações estruturais vesicais em ratos, especialmente no que diz respeito à remodelação colágena. Método: Foram utilizadas 45 ratas da raça Wistar, de quatro semanas de idade, divididas em três grupos: 1) controle com dieta comum padrão para roedores (DN); 2) modelo de OIV com DN e 3) controle com dieta de alto teor lipídico (DATL 1,25% colesterol). Análise sérica do colesterol e fração LDL e medição do peso corporal foram realizadas em todos os animais inicialmente e no final do estudo. Com quatro semanas de estudo, as ratas dos grupos 1 e 3 foram submetidas à cirurgia simulada, enquanto os animais do grupo 2 foram efetivamente submetidos à cirurgia de OIV parcial. Após dissecção da uretra, fez-se uma ligadura parcial com Nylon 5-0, com um lúmen residual de aproximadamente 1 mm. Após seis semanas, todos os animais foram submetidos à remoção de suas bexigas e então sacrificados. Análise morfológica foi realizada através da coloração de Picrosirius vermelho e de imuno-histoquímica para os colágenos tipos I e III. As variáveis categóricas fora expressas em médias ± desvio padrão e a comparação entre grupos realizada pelo método ONEWAY-ANOVA e pela análise de comparações múltiplas de Tukey, quando houve diferença. A significância estatística foi definida como p < 0,05. Resultados: Este estudo demonstrou que a DATL em ratas Wistar proporcionou aumento significativo das taxas de LDL-colesterol (p < 0,001) e do peso corporal (p = 0,017) em relação a ratas alimentadas com DN no período de dez semanas. Além disto, induziu alterações morfológicas significativas da matriz extracelular, no que diz respeito à remodelação das fibras colágenas imaturas e do colágeno tipo III em relação ao grupo controle (p = 0,002 e p = 0,016, respectivamente), de forma semelhante ao que ocorre no modelo experimental de OIV parcial crônica. Conclusão: A dieta hipercolesterolêmica administrada a ratas Wistar promoveu, além de aumento do peso corporal e elevação da fração LDL-colesterol, alterações significativas na composição colágena da MEC vesical. / Purpose: Preserved bladder function is defined as the adequate storage and emptying of its urinary content. Compliance is an important factor for these functions and is directly related to the extracellular matrix composition. Its abnormalities can lead to bladder dysfunctions. The collagen represents 50% of bladder stroma, playing an important role in the bladder adaptation to specific pathologic conditions. Types I and III collagens are the most prevalent in bladder wall whereas type III collagen is the first synthesized in reparation and fibrosis processes. Bladder outlet obstruction (BOO) promotes this process and hypercholesterolemia is also believed to create conditions for it, although no morphologic association has already been demonstrated. In this study we aimed to verify if hypercholesterolemic diet promotes structural bladder wall modifications, regarding the collagen remodeling. Methods: Forty-five female heterogenic Wistar 4 weeks-old rats were divided into three groups: 1) control fed on a normal diet (ND); 2) BOO model fed on a ND and 3) control fed on a hypercholesterolemic diet (HCD 1.25% cholesterol). Initially, serum cholesterol, LDL-cholesterol and body weight were measured. Four weeks later groups 1 and 3 underwent a sham operation while group 2 underwent a partial BOO operation. After the urethra was dissected a 5-zero nylon suture was passed and tied loosely around the urethra with a 22G needle besides it. Six weeks later the bladders of all animals were removed, serum cholesterol and LDL-cholesterol analysis was performed, body weight was measured and then they were sacrificed. Morphological analysis was performed by Picrosirius red staining and immunohistochemistry for types I and III collagen. Statistical analysis was done comparing groups by the Oneway-Anova method and Tukey multiple comparisons when needed. Significance was considered when p < 0.05. Results: Wistar rats fed on a HC diet had a significant increase of LDL-cholesterol levels (p < 0.001) and body weight (p = 0.017), when compared to the control group fed on a normal diet in the period of ten weeks. Moreover, HC diet induced significant morphological alterations of the extracellular matrix of the bladder wall, regarding immature collagen fibers and type III collagen remodeling, when compared to the control group (p = 0.002 and p = 0.016, respectively), resembling the process promoted in the BOO model. Conclusions: A hypercholesterolemic diet in Wistar rats promoted, besides the body weight and LDL-cholesterol increase, morphological alterations of the bladder extracellular matrix, regarding collagen remodeling.

Medir a espessura da parede vesical (EPV) através da ultrassonografia, correlacioná-la com os parâmetros urodinâmicos e avaliar o papel destes parâmetros para lesão do trato urinário superior. Avaliar também o papel das alterações da forma da bexiga nos resultados de injeção de toxina botulínica tipo-A (BTX-A) no detrusor em pacientes com lesão medular traumática (LMT). Trata-se de dois estudos. O primeiro é um estudo transversal de 272 pacientes com LMT submetidos à ultrassonografia renal e de bexiga e estudo urodinâmico. A parede anterior da bexiga foi medida e comparada com os dados urodinâmicos. A cistografia foi realizada em 57 pacientes. O segundo foi um estudo prospectivo avaliando os resultados da injeção de BTX-A no detrusor em 27 pacientes considerando os achados urodinâmicos (pré e pós procedimento) e as deformidades da bexiga (cistografia). A média da EPV foi de 3,94 mm e foi estatisticamente maior em pacientes com hiperatividade detrusora neurogênica associada à dissinergia vesicoesfincteriana (HDN/DVE), em comparação com aqueles sem DVE (p<0,001). Essa média também foi maior em pacientes com complacência < 20 mL/cmH2O, comparada aos pacientes com complacência &#8805; 20 mL/cmH2O (p<0,001). A média da pressão detrusora máxima (Pdet Max) foi estatisticamente maior nos pacientes com refluxo vesicoureteral (RVU) em comparação com aqueles sem RVU (100,7 vs 61,2 cmH2O respectivamente, p=0,022). Pacientes com complacência < 20 mL/cmH2O apresentaram prevalência de hidronefrose 4,2 vezes maior, comparada aos pacientes com complacência &#8805; 20 mL/cmH2O. Não houve associação estatística entre EPV e hidronefrose ou RVU. Vinte e sete pacientes foram submetidos à injeção de BTX-A no detrusor. A média de tempo de continência urinária foi de 8 meses. Nove pacientes (33,3%) tinham forma vesical alterada e 8 casos (29,6%) tinham divertículos. A capacidade cistométrica máxima, Pdet max, volume reflexo e complacência não apresentaram diferença significativa na presença de divertículos ou alteração da forma. O aumento da EPV está associado à complacência < 20 mL/cmH2O e HDN/DVE em pacientes com LMT. No entanto, não houve relação entre a EPV e hidronefrose ou RVU. Baixa complacência e HDN/DVE são os principais fatores de risco para dano ao trato urinário superior. A presença de divertículos ou alteração da forma vesical não influenciou nos resultados após injeção de BTX-A no detrusor. / To investigate the ultrasonographic bladder wall thickness (BWT), urodynamic parameters and evaluate the role of such measurements for the upper and lower urinary tract deterioration and also assess the role of changes in bladder shape in the outcome of botulinum toxin type A (BTX-A) into the detrusor in patients with spinal cord injury (SCI). There are two studies. First study was a cross-sectional study involving two hundred and seventy two patients with SCI who underwent renal and bladder ultrasonography and urodynamic evaluation. The anterior bladder wall was measured and compared to urodynamic data. Cystography was done in 57 patients. The second was a prospective study about injection of BTX-A into the detrusor performed in 27 patients considering urodynamic parameters and cystography findings. Mean BWT was 3.94 mm. BWT was statistically higher in patients with neurogenic detrusor overactivity associated to detrusor sphincter dyssynergia (NDO/DSD) and in those with compliance < 20 mL/cmH2O. Patients with low compliance (< 20 mL/cmH2O), had 4.2 times higher prevalence of hydronephrosis, compared to patients with compliance &#8805; 20 mL/cmH2O. Mean of Pdet max was statistically higher in patients with vesicoureteral reflux (VUR) compared to those without (100.7 vs 61.2 cmH2O respectively, p=0.022). There was no statistical association between BWT and hydronephrosis or VUR. Twenty seven patients underwent injection of BTX-A into the detrusor. The average time of urinary continence was 8 months. Nine patients (33.3%) had altered bladder shape and 8 cases (29.6%) had diverticula. The maximum cystometric capacity, NDO, reflex volume and compliance showed no statistically significant difference in the presence of diverticula or altered bladder shape. Increased BWT is associated with low compliance and NDO/DSD in patients with SCI. However, there was no relationship between BWT and hydronephrosis or VUR. Low compliance and NDO/DSD are the main risk factors for the upper urinary tract damage. The presence of diverticula or changes in bladder shape did not influence the results after injection of BTX-A into the detrusor.

The diagnosis of BH is defined from the clinical symptoms, but the voiding diary and urodynamic studies are good tools for objective evaluation of this pathology. There are several forms of treatment for OAB, are the main pharmacological and physical therapy, physical therapy has been being considered an important option in a clinical setting. OBJECTIVES: to do a systematic review article about physical therapy in the treatment of female miccional urgency, to evaluate and compare the effects, discomfort and improvement in quality of life (QOL) of vaginal electrostimulation and percutaneous tibial nerve stimulation (PTNS) in women with overactive bladder. METHODS: We conducted a comparative, prospective, randomized trial of physiotherapy in the sector of the Hospital Materno Infantil (HMI) in Goiânia-GO, from march 2010 to august 2011. We randomized 40 women with urodynamic diagnosis of detrusor overactivity, mixed incontinence with predominant symptoms of overactive bladder or urinary urgency only in two groups: vaginal electrical stimulation (n=20) and PTNS (n=20), being held 10 sessions in each group. We used urodynamic studies, voiding diary and QoL questionnaire of King's Health Questionnaire (KHQ) before and after the two procedures, and then visual analog scale. Statistical analysis used: Fisher exact tests, chi quadratic, U Mann Whitney and Wilcoxon tests with a significance level of 0.05. RESULTS: In voiding diary was a reduction in urinary frequency, urge incontinence, nocturia and urgency in both groups. The urgency was present in all women and disappeared in 90% in the PTNS group (p<0.001) and 80% in vaginal electrical stimulation (p<0.001). According to urodynamic evaluation, the group of vaginal electrostimulation showed disappearance of detrusor overactivity in 60% (p=0.005) and PTNS in 75% (p= 0.002). The urodynamics showed significant differences in some parameters analyzed within each specific group and to compare the two groups was not observed differences. The scale and the KHQ domains of the two procedures had similar results as physical therapy to improve QOL, but no significant difference between them. In relation to the discomfort of procedures, PTNS in 80% of women reported no discomfort and 80% reported vaginal electrostimulation mild to moderate discomfort (p<0.001). CONCLUSION: There was no significant difference in the effects and QOL between the vaginal electrical stimulation and PTNS. The PTNS promoted less discomfort for women. / INTRODUÇÃO: A síndrome de bexiga hiperativa (BH) é uma patologia do trato urinário inferior que afeta negativamente a qualidade de vida (QV) das mulheres, cujo principal sintoma para a sua definição é a urgência miccional, com ou sem incontinência, geralmente acompanhada por polaciúria e noctúria, na ausência de fatores metabólicos, infecciosos ou locais. O diagnóstico da BH é definido a partir dos sintomas clínicos, porém o estudo urodinâmico e o diário miccional são bons instrumentos de avaliação objetiva dessa patologia. Existem diversas formas de tratamento para a BH, os principais são o farmacológico e a fisioterapia, uma vez que a fisioterapia vem sendo considerada como uma opção de relevância no meio clínico. OBJETIVO: Fazer um artigo de revisão sistemática sobre a atuação da fisioterapia no tratamento da urgência miccional feminina, avaliar e comparar os efeitos, o desconforto e a melhoria na qualidade de vida (QV) da eletroestimulação vaginal e da eletroestimulação transcutânea do nervo tibial posterior (PTNS) em mulheres com bexiga hiperativa. MÉTODOS: Foi realizado um estudo comparativo, prospectivo e randomizado no setor de fisioterapia do Hospital Materno Infantil (HMI) de Goiânia-GO, no período de março 2010 a agosto de 2011. Foram randomizadas 40 mulheres com o diagnóstico urodinâmico de hiperatividade do detrusor, incontinência urinária mista com predomínio dos sintomas de bexiga hiperativa ou apenas urgência miccional em dois grupos: eletroestimulação vaginal (n=20) e PTNS (n=20), sendo realizado 10 sessões em cada grupo. Foram utilizados o estudo urodinâmico, diário miccional e o questionário de QV King s Health Questionnaire (KHQ) antes e após os dois procedimentos, e posteriormente a escala visual analógica. Para análise estatística utilizou-se: os testes Exato de Fisher, Qui Quadrad, u Mann Whitney e Wilcoxon com nível de significância de 0,05. RESULTADOS: No diário miccional houve a redução da frequência miccional, urgeincontinência, noctúria e urgência nos dois grupos. A urgência estava presente em todas as mulheres e desapareceu em 90% no grupo PTNS (p<0,001) e 80% na eletroestimulação vaginal (p<0,001). Conforme avaliação urodinâmica, o grupo da eletroestimulação vaginal apresentou desaparecimento da hiperatividade detrusora em 60% (p=0,005) e na PTNS 75% (p=0,002). A urodinâmica demonstrou diferença significante em alguns parâmetros analisados dentro de cada grupo específico e ao comparar os dois grupos não foi constatado diferenças. Quanto à escala e os domínios do KHQ os dois procedimentos da fisioterapia apresentaram resultados similares quanto à melhora da QV, mas sem diferença significativa entre eles. Em relação ao desconforto dos procedimentos, na PTNS 80% das mulheres relataram ausência de desconforto e na eletroestimulação vaginal 80% relataram desconforto leve a moderado (p<0,001). CONCLUSÃO: não houve diferença significativa nos efeitos e na QV entre a eletroestimulação vaginal e a PTNS. A PTNS promoveu menos desconforto para as mulheres.

This thesis concerns the investigation of novel immunotherapies for cancer eradication. CpG therapy was used in order to target antigen-presenting cells (APCs), facilitating antigen presentation and activation of T cells. Blockade of the two major immune checkpoint regulators (CTLA-4 and PD-1) was also studied to ensure proper and sustained T cell activation. The therapies were investigated alone and compared to BCG, the standard immunotherapy in the clinic today for bladder cancer. In addition, CpG as well as BCG was combined with CTLA-4 or PD-1 blockade to examine if the combination could improve therapy. Single and combination strategies were assessed in an experimental bladder cancer model. In addition, one of the therapies (local aCTLA-4 administration) was evaluated in an experimental pancreatic cancer model. To be able to study the effects of CpG in humans, a human whole blood loop system has been used. This allowed us to dissect the potential interplay between CpG and complement. CpG was found to be superior to the conventional therapy, BCG, in our experimental model and T cells were required in order for effective therapy to occur. Used as a monotherapy, CTLA-4 blockade but not PD-1 blockade, prolonged survival of mice. When CTLA-4 or PD-1 blockade was combined with CpG, survival was enhanced and elevated levels of activated T cells were found in treated mice. In addition, Treg levels were decreased in the tumor area compared to tumors in control treated mice. CTLA-4 blockade was also effective when administrated locally, in proximity to the tumor. Compared to systemic CTLA-4 blockade, local administration gave less adverse events and sustained therapeutic success. When CpG was investigated in a human whole blood loop system it was found to tightly interact with complement proteins. This is an interesting finding which warrants further investigation into the role of TLRs in complement biology. Tumor therapy could be affected either negatively or positively by this interaction. The results presented herein are a foundation for incorporating these combination therapies into the clinic, specifically for bladder cancer but in a broader perspective, also for other solid tumors such as pancreatic cancer.

Copy number variation (CNV) comprises a recently discovered kind of variation involving deletion and duplication of DNA segments of variable size, ranging from a few hundred basepairs to several million. By altering gene dosage levels or disrupting proximal or distant regulatory elements CNVs create human diversity. They represent also an important factor in human evolution and play a role in many disorders including cancer. Array-based comparative genomic hybridization as well as expression arrays are powerful and suitable methods for determination of copy number variations or gene expression changes in the human genome. In paper I we established a 32K clone-based genomic array, covering 99% of the current assembly of the human genome with high resolution and applied it in the profiling of 71 healthy individuals from three ethnic groups. Novel and previously reported CNVs, involving ~3.5% of the genome, were identified. Interestingly, 87% of the detected CNV regions overlapped with known genes indicating that they probably have phenotypic consequences. In papers II through IV we applied this platform to different tumor types, namely two collections of brain tumors, glioblastoma (paper II) and medulloblastoma (paper III), and a set of bladder carcinoma (paper IV) to identify chromosomal alterations at the level of DNA copy number that could be related to tumor initiation/progression. Tumors of the central nervous system represent a heterogeneous group of both benign and malignant neoplasms that affect both children and adults. Glioblastoma and medulloblastoma are two malignant forms. Glioblastoma often affects adults while the embryonal tumor medulloblastoma is the most common malignant brain tumor among children. The detailed profiling of 78 glioblastomas, allowed us to identify a complex pattern of aberrations including frequent and high copy number amplicons (detected in 79% of samples) as well as a number of homozygously deleted loci. These regions encompassed not only previously reported oncogenes and tumor suppressor genes but also numerous novel genes. In paper III, a subset of 26 medulloblastomas was analyzed using the same genomic array. We observed that alterations involving chromosome 17, especially isochromosome 17q, were the most common genomic aberrations in this tumor type, but copy number alterations involving other chromosomes: 1, 7 and 8 were also frequent. Focal amplifications, on chromosome 1 and 3, not previously described, were also detected. These loci may encompass novel genes involved in medulloblastoma development. In paper IV we examined for the presence of DNA copy number alterations and their effect on gene expression in a subset of 21 well-characterized Ta bladder carcinomas, selected for the presence or absence of recurrences. We identified a number of novel genes as well as a significant association between amplifications and high-grade and recurrent tumors which might be clinically useful. The results derived from these studies increase our understanding of the genetic alterations leading to the development of these tumor forms and point out candidate genes that may be used in future as targets for new diagnostic and therapeutic strategies.

La present tesi avalua les diferències entre homes i dones quant a les característiques sociodemogràfiques i clínicopatològiques, procés diagnòstic, tractament i pronòstic en una sèrie de casos diagnosticats de novo de càncer de bufeta en 18 hospitals de 5 regions espanyoles (estudi EPICURO). També s'estudia l'associació entre tabac i risc de càncer de bufeta segons el sexe en un estudi agregat d'estudis cas-control europeus i nord-americans de càncer de bufeta.Es trobaren diferències entre sexes quant a la incidència de la malaltia, en algunes característiques anatomopatològiques dels tumors i quant a tractament. No es varen observar diferències entre sexes davant d'un mateix nivell d'exposició al tabac. També s'observaren diferències entre homes i dones quant al risc de recidivar i de progressar dels tumors vesicals superficials, però no en el risc de morir dels pacients amb tumors invasius. / The thesis evaluates differences related to sociodemographic and clinic-pathological characteristics, diagnostic tests, treatment and prognosis of bladder cancer patients newly diagnosed in 18 hospitals from 5 Spanish areas according to sex. The work also assess the association between tobacco and bladder cancer risk according to sex in a pooled analysis of case-control studies of bladder cancer from Europe and North America.Differences between sex concerning disease incidence, pathological characteristics and treatment were observed. The relative risk of bladder cancer associated with tobacco was similar in both sex. Differences between men and women were observed regarding risk of recurrence and progression of their superficial tumors but not regarding risk of death because of an invasive tumor.

L'objectiu d'aquest tesi és avaluar els diferents passos en el camí que va des de l'exposició a contaminants atmosfèrics/PAHs fins a la malaltia, el càncer de bufeta urinària. Es van mesurar partícules ultrafines a Barcelona. S'ha avaluat l'exposició a contaminació atmosfèrica en un estudi cas-control, recollint informació sobre la història residencial incloent diversos indicadors de l'exposició a contaminació atmosfèrica i altres factors de risc potencials. Es va dur a terme una revisió sistemàtica de la literatura per avaluar si els nivells de metabòlits del pirè i els aductes d'ADN i de proteïnes es correlacionaven amb nivells baixos d'exposició a PAHs. Vam mesurar els nivells d'aductes d'ADN en un subgrup d'individus de l'estudi cas-control amb la tècnica del radioetiquetatge amb fòsfor-32, tractament de la nucleasa P1. Vam analitzar 22 SNPs en set gens de la via de reparació de l'ADN per excisió de nucleòtids. / The aim of this thesis is to evaluate the different steps in the pathway from exposure (air-contaminants/PAHs) to disease (bladder cancer). We measured ultrafine particles in Barcelona. We evaluated the exposure to air pollutants in a case-control study, collecting information on the residential history with proxies for exposure to air pollution and other potential risk factors. We did a systematic review of the literature to evaluate if pyrene metabolites and DNA and protein adducts are correlated with low level exposure to PAHs. We measured bulky DNA adducts in a subgroup of subjects of the case-control study using 32P-Postlabeling, nuclease P1 treatment. We analyzed 22 SNPs in 7 genes of the nucleotide excision repair pathway.

Paclitaxel is one of the most successful drugs for the treatment of cancer because of its ability to target tubulin, block cell cycle progression at mitosis, and induce apoptosis. Despite the success of Paclitaxel, the development of drug resistance hampers its clinical applicability. Paclitaxel is used in malignant tumors in the present research, including non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC), head-neck scale epitheliomatous, urinary bladder cancer, tumor of the reproduction organ and so on. Clinical treatment of paclitaxel be injected 250mg/m2 to previously non-treated patients of small lung cancer its effect about 34% and previously non-treated patients of non-small lung cancer its effect about 21% to 24% . On the other hand we had established a taxol-resistant human lung carcinoma subline A549R by paclitaxel to compare the different proteins with A549 wild type and treat the different concention of paclitaxel with MTT assay so as to observe the tolerance dosage of subline growth.We obtained the patient¡¦s specimens of lung cancer to treat with paclitaxel some of resistant and some of non-resistant to compare differentially expressed proteins between normal and tumor. When we cultured taxol-resistant human lung carcinoma subline in which paclitaxel and calcium regulate growth, owing to the proteins of changes result to resistance. The extraction cell subline and specimens were analyzed by 2-D electrophoresis patterns and we found that interact paclitaxel with calcium it is the important factor of drug resistant. Verified from clinical treatment might have hypercalcemia in malignant tumors and calcium ion may increase paclitaxel drug resistance and hypercalcemia patient will be more insensitive to paclitaxel treatment.

During recent years, significant advances have been made in the field of molecular therapy in urologic oncology, mainly for advanced renal cell carcinoma. In this hitherto largely treatment-refractory disease, several agents have been developed targeting the von Hippel-Lindau metabolic pathway which is involved in carcinogenesis and progression of the majority of renal cell carcinomas. Although cure may not be expected, new drugs, such as the multikinase inhibitors sorafenib and sunitinib and the mammalian target of rapamycine inhibitor temsirolimus, frequently stabilize the disease course and may improve survival. Fewer data are available supporting molecular therapies in prostate, bladder, and testicular cancers. Preliminary data suggest a potential role of high-dose calcitriol and thalidomide in hormone-refractory prostate cancer, whereas targeted therapies in bladder and testicular cancers are still more or less limited to single-case experiences. The great theoretical potential and the multitude of possible targets and drug combinations, however, support further research into this exciting field of medical treatment of urologic malignancies. / Dieser Beitrag ist mit Zustimmung des Rechteinhabers aufgrund einer (DFG-geförderten) Allianz- bzw.
