A síndrome mielodisplásica primária (SMD) compreende um grupo de doenças hematopoéticas clonal de célula tronco pluripotente cacacterizada por vários graus de pancitopenia e alterações morfológica das células hematopoeticas e risco aumentado de transformação para leucemia mielóide aguda. A citogenética e a morfologia da medula óssea desempenham um papel fundamental para o diagnóstico e o prognóstico desses pacientes. Alterações cromossômicas são encontradas em aproximadamente 30-50% dos casos. Devido à importância da análise desses fatores para escolha terapêutica, torna-se necessário definir as alterações morfológicas e citogenéticas que possam contribuir para o prognóstico. Esse trabalho visa correlacionar as características morfológicas e citogenéticas da medula óssea em pacientes com SMD primária com as classificações OMS e FAB e com o IPSS. Foram estudados 32 pacientes com SMD primária diagnosticados entre 2000 e 2009 no HUPE-UERJ. As características clínicas foram analisadas através do levantamento de prontuários. A análise citogenética foi feita pela técnica de bandeamento GTG em células da medula ossea. A análise morfológica da biópsia de medula óssea e do mielograma foram realizadas através da revisão de lâminas. Vinte e três pacientes foram classificados em estágios iniciais da doença (22 AR, 1 ARSA) e 9 em estágio avançado AREB de acordo com a FAB. Alterações cromossômicas foram detectadas em 16 pacientes (50%). As mais frequentes foram: del(11)(q23) e del(17p). Dos pacientes com doença avançada, seis (66%) apresentaram aumento significativo da relação M:E (p=0,003) e sete (77%) possuíam alterações arquiteturais acentuadas (p<0,001) em comparação ao grupo de doença inicial. Pacientes classificados como intermediário 2 e alto risco pelo IPSS tiveram importante perda arquitetural (p<0,001), número significativamente maior de micromegacariócitos (p=0,017) e seis (85%) sofreram transformação leucêmica (p=0,006). ALIP foi significantemente aumentada nos pacientes de pior prognóstico (p=0,0 1) e naqueles com doença avançada (p=0,001). Nossos resultados apresentaram implicações potenciais para o diagnóstico e o prognóstico da SMD primária. As alterações morfológicas foram associadas com as classificações FAB, OMS e com os grupos de risco segundo o IPSS. / The primary myelodysplastic syndrome (MDS) comprises a heterogeneous group of clonal bone marrow disorders characterized by varying degrees of pancytopenia and morphological abnormalities of hematopoietic cells, and an increased risk of transformation into acute myeloid leukemia. The morphology and the cytogenetic of bone marrow play a key role in the diagnosis and the prognosis. Chromosomal abnormalities are found in 30-50% of cases. Due to the importance of analyzing these factors for therapeutic choice, it becomes necessary to define the morphological and the cytogenetic changes which could contribute to the prognosis.The aim of this study was to analyze the morphological and cytogenetic features of bone marrow and their correlations with FAB and WHO clasification and IPSS. We studied 32 patients with primary MDS between 2000 - 2009. The clinical data was recovered from medical records. Morphological characteristics were analyzed through a review of bone marrow biopsies and mielogram slides. Cytogenetic analysis was performed by GTG banding from bone marrow cells. The patients were classified according to FAB in initial stages: RA (22 patients) and RARS (1 patient) and nine in advanced stages - RAEB. Chromosomal abnormalities were detected in 16 patients (50%). The most frequent abnormalities were: del(11)(q23) and del(17p). Patients with advanced disease, six (66%) had significant increased M:E ratio (p=0.003) and seven patients (77%) had increased architectural changes (p<0.001). Patients classified as intermediary 2 and high risk according IPSS had important architectural loss (p<0.001), presence of micromegakaryocyte was considered significant higher (p=0.017) and six patients (85%) underwent leukemia transformation (p=0.006). ALIP was significant higher in the patients with a worse prognosis (p=0.021) and advanced stage of disease (p=0.001). Our results showed potential implications for diagnosis and prognosis of MDS. The morphological findings in this study were associated with FAB and WHO groups and prognostic risk (IPSS).

A pesquisa se ocupa especificamente do Termo de Parceria, contrato que potencializa as relações entre Poder Público e Organizações da Sociedade Civil de Interesse Público- OSCIP. A ênfase do trabalho recai sobre a observação do conjunto de instrumentos de controle à disposição do parceiro público, pois as ONGs, contratadas pelo Estado, recebem fomento do governo para a realização de um projeto social, que em tese, se conjuga com a política pública do Poder Executivo. Alguns pontos frágeis da regulação das OSCIPs evidenciam aspectos da inatividade do Estado, como agente regulador da iniciativa privada. Nesse ponto, a investigação se desloca para Portugal, tendo em vista a realização de estudo análogo, realizado junto as Instituições Particulares de Solidariedade Social IPSS, que também contratam com a Administração Pública para a promoção dos mesmos fins. Dessa forma, a regulação portuguesa pode fornecer elementos para fortalecer a pesquisa realizada no Brasil

Introduction: Obesity has been suggested to be one of the risk factors for erectile dysfunction (ED) and lower urinary tract symptoms (LUTS). Bariatric surgery has been used for the treatment of obesity and has been suggested to have a significant impact on obesity-related conditions such as diabetes mellitus, ED and LUTS. Previous studies have investigated the effect of bariatric surgery on erectile and urological function in obese men; however those studies used long-term time points post-operatively (more than 1 month). Since it is now known that bariatric surgery can potentially induce glycaemic improvement within one week independent of weight loss, this study aimed to investigate the short-term effect in order to test the hypothesis as to whether improvement in urogenital function after bariatric surgery is due to weight loss or whether it is due to glycaemic improvement. Aim: To evaluate the baseline characteristics of patients with erectile dysfunction and to determine the early effects of bariatric surgery on erectile and urological function in morbidly obese men.

Objective: To assess in a prospective trial the influence of the amount of tissue resected at transurethral resection of the prostate (TURP) for benign prostatic enlargement on the symptom improvement as assessed by symptom scores. Methods: Between December 1996 and August 1998 a total of 138 men (mean age 68.2, range 53–89) with symptomatic benign prostatic enlargement who underwent TURP participated in this prospective study. Patients were assessed preoperatively with the International Prostate Symptom Score (IPSS), the American Urological Association Bother Score (AUA–BS) and the Benign Prostatic Hyperplasia Impact Index (BPH–II) as well as urinary flow rate measurements (Qmax) and prostate volume (PV) and residual urine determination by ultrasound. The amount of tissue resected was weighed. Patients were followed with reevaluation of Qmax, residual urine and the symptom and bother scores at 3 and 6 months. Results: A close correlation between preoperative PV (mean 49.0 ml, SD 22.0, range 13–140) and the resected tissue weight (RTW, mean 24.7 g, SD 18.0, range 6–128) was seen (r = 0.75, p<0.001). Age was correlated with preoperative PV (r = 0.23, p<0.05). While significant mean improvements in Qmax, residual volume and IPSS, AUA–BS and BPH–II were found 3 and 6 months postoperatively, a negative correlation was seen between the RTW and the IPSS, the AUA–BS and the BPH–II 3 months after TURP (r = –0.23, p<0.024; r = –0.23, p<0.025; r = –0.20, p = 0.05). No statistically significant correlation was seen between symptom change and the percentage of PV removed or the residual prostatic weight. Classification of the patients into groups depending on preoperative PV (<30, 31–50, 51–70 and >70 ml) showed a tendency for patients with larger PV to gain more symptom improvement postoperatively. Conclusions: Early symptom improvement after TURP will depend on the amount of tissue removed but the relationship is weak and affected by several other confounding factors. Apparently, the symptomatic improvement after TURP is not primarily dependent on the relative completeness of the resection. Patients with larger prostates and larger RTW tend to gain more symptomatic benefit from TURP than do patients with smaller prostates. / Dieser Beitrag ist mit Zustimmung des Rechteinhabers aufgrund einer (DFG-geförderten) Allianz- bzw.

Kompetenzzellenbasierte (regionale) Netze stellen besondere Anforderungen an die Modellierung, Planung und Gestaltung der Logistikstrukturen. Für die Logistikstrukturmodellierung werden ein generischer Beschreibungsrahmen für produktionslogistische soziotechnische Systeme, Definitionen u.a. zum zentralen Begriff Logistikstruktur sowie ein 3-Ebenen-Modell und Strukturtypen für eine vertiefende Materialflussanalyse und -synthese bereitgestellt. Für die Logistikstrukturplanung wird darauf aufbauend mit der Methode der Integrativen Prozess- und Systemstrukturierung (IPSS) eine Methode zur Behandlung von Strukturierungsproblemen konzipiert, die sowohl speziell für kompetenzzellenbasierte Netze als auch allgemein für Produktions- und Logistiksysteme angewandt werden kann. Für die Logistikstrukturgestaltung werden unter Modell- und Methodenverwendung Szenarien sowie Gestaltungs- und Vorzugslösungen für den Materialfluss abgeleitet. / Competence-cell based (regional) networks put special requirements on the modelling, planning and design of logistics structures. For the modelling of logistics structures, a generic description framework for production logistic sociotechnical systems, definitions for, amongst others, the central term logistics structure as well as a 3-layer-model and structure types for a more detailed material flow analysis and synthesis are provided. For the planning of logistics structures, the Method of Integrative Process and System Structuring (IPSS) is developed as a method for handling structuring problems. It can be applied especially to Competence-cell based networks as well as generally to production and logistics systems. For the design of logistics structures, scenarios as well as design and preference solutions for the material flow are derived.
