A droga pertence a uma nova classe de medicamentos por ser uma terapia-alvo, que foca especificamente nas células tumorais, na tentativa de tratar as doentes sem atingir as saudáveis, garantindo, assim, maior precisão ao tratamento, menos efeitos colaterais e, consequentemente, melhora na qualidade de vida do paciente. Além disso, Daratumumabe é o único anticorpo monoclonal aprovado para o mieloma múltiplo e introduz, no tratamento da doença, o conceito de imuno-oncologia, que usa o próprio sistema imunológico do paciente para combater o câncer. Os resultados apresentados fazem Daratumumabe ser considerado no meio científico como um marco na evolução do tratamento para mieloma múltiplo. Segundo o hematologista do Hospital Israelita Albert Einstein, Dr. Jairo Sobrinho, o medicamento demonstrou resultados considerados sem precedentes em seus estudos clínicos, tanto em uso exclusivo quanto em combinação com outras drogas. O retardo na progressão da doença e as taxas de resposta foram os achados mais impactantes dessas pesquisas. Atualmente, o tratamento no Brasil é feito com quimioterapia, drogas antineoplásicas, administração de corticoides ou transplante de medula óssea. Quando utilizado em 2ª linha de tratamento em combinação com bortezomibe e dexametasona, Daratumumabe reduz o risco de avanço da doença em 78%.

Early allograft dysfunction (EAD) had been related to poor transplant outcomes during the early years of liver transplantation. We sought to determine the incidence of EAD at our unit and to evaluate its impact on posttransplant outcomes. This single-center retrospective study included primary deceased donor liver grafts transplanted under the model for end-stage liver disease system. EAD was defined as a peak values of aminotransferase >2000 IU/mL during the first week or an international normalized ratio of ≥1.6 and/or bilirubin ≥10 mg/dL at day 7. The main endpoints were patient and graft survivals. Patients with versus without EAD showed similar recipient characteristics. Donors who experienced EAD who comprises 56% of recipients were heavier with larger body mass indices. EAD was an independent risk factor for allograft loss. Most retransplants were performed early due to nonfunction. The primary nonfunction rate among subjects with versus without EAD were 7% and 12% respectively (P < .05). Patient survival among those with EAD was 87.4%, while without EAD it was 90% (P = NS) with graft survivals of 81.4% and 88.7% respectively (P < .05). Patients with EAD show a significantly higher risk for allograft loss, but with a comparable survival after transplantation. Despite their worse outcomes, it seems that not all of these recipients behave equally. Copyright © 2012 Elsevier Inc. All rights reserved.

To assess the results of palmar and axillary hyperhidrosis treatment in males and females using low doses of oxybutynin. A retrospective analysis was conducted in 395 women and 170 men followed up in our service with complaint of palmar and axillary hyperhidrosis. A total of 70% of patients in both groups presented partial or great improvement in the level of hyperhidrosis after treatment. The best results were obtained in the female group, in which 40% classified their improvement as "great". Approximately 70% of the patients in both groups improved their quality of life after medical therapy and 30% presented no change in condition. Gender is not a factor that significantly interferes in oxybutynin treatment results. Quality of life indices and clinical improvement level were similar in men and women.

Chronic lymphocytic leukemia (CLL) is the most common leukemia in the Western world, characterized by peripheral blood B-cell lymphocytosis as well as lymphadenopathy, organomegaly, cytopenias, and systemic symptoms. Chronic lymphocytic leukemia cells have a distinctive immunophenotype, and the disease has a characteristic pattern of histological infiltration in the lymph node and bone marrow. The clinical course of CLL is heterogeneous, with some patients presenting with very indolent disease and other patients having a more aggressive malignancy. It is known that genetic abnormalities underlie this difference in clinical presentation. Some patients may present solely with lymphadenopathy, organomegaly, and presence of infiltrating monoclonal B cells with the same immunophenotype as CLL cells, but lacking peripheral blood lymphocytosis. This disease is called small lymphocytic lymphoma (SLL) and has been considered for almost 2 decades to be the tissue equivalent of CLL. Both CLL and SLL are currently considered different manifestations of the same entity by the fourth edition of the World Health Organization Classification of Tumours of Haematopoietic and Lymphoid Tissues. It is suspected that differential expression of chemokine receptors (e.g., reduced expression of R1 and CCR3 in SLL cells), integrins (e.g., CLL cells have lower expression of integrin αLβ2), and genetic abnormalities (a higher incidence of trisomy 12 and lower incidence of del(13q) is found in SLL) may explain some of the clinical differences between these 2 disorders. However, there is still a lack of knowledge on the precise biological basis underlying the different clinical presentations of CLL and SLL. It is expected that future studies will shed light on the pathophysiology of both disorders. © 2012 by Lippincott Williams & Wilkins.

Patents for many key biological agents will soon expire. Third-party companies are, therefore, in the process of developing their own versions, termed biosimilar agents, of these innovator products. However, manufacture of biosimilar agents is complicated by the requirement for their production in biological systems, small variations in which can influence the structure, activity and metabolism of the biosimilar product. The development of biosimilar therapies for the treatment of patients with rheumatic diseases could potentially result in substantial cost savings for patients and health care providers, and consequently, increased availability of effective therapies. However, legislation that regulates the manufacture, registration and approval of biosimilar therapies varies considerably between different countries. In addition, major safety and efficacy concerns must be addressed before a rheumatologist can routinely substitute an innovator pharmaceutical with a biosimilar product. © 2012 Macmillan Publishers Limited.

The aim of the current study was to monitor the migration of superparamagnetic iron oxide nanoparticle (SPION)-labeled C6 cells, which were used to induce glioblastoma tumor growth in an animal model, over time using magnetic resonance imaging (MRI), with the goal of aiding in tumor prognosis and therapy. Two groups of male Wistar rats were used for the tumor induction model. In the first group (n=3), the tumors were induced via the injection of SPION-labeled C6 cells. In the second group (n=3), the tumors were induced via the injection of unlabeled C6 cells. Prussian Blue staining was performed to analyze the SPION distribution within the C6 cells in vitro. Tumor-inducing C6 cells were injected into the right frontal cortex, and subsequent tumor monitoring and SPION detection were performed using T2- and T2*-weighted MRI at a 2T field strength. In addition, cancerous tissue was histologically analyzed after performing the MRI studies. The in vitro qualitative evaluation demonstrated adequate distribution and satisfactory cell labeling of the SPIONs. At 14 or 21 days after C6 injection, a SPION-induced T2- and T2*-weighted MRI signal reduction was observed within the lesion located in the left frontal lobe on parasagittal topography. Moreover, histological staining of the tumor tissue with Prussian Blue revealed a broad distribution of SPIONs within the C6 cells. MRI analyses exhibit potential for monitoring the tumor growth of C6 cells efficiently labeled with SPIONs.

To evaluate effectiveness of the use of platelet-rich plasma as coadjuvant for union of long bones. The search strategy included the Cochrane Library (via Central) and MEDLINE (via PubMed). There were no limits as to language or publication media. The latest search strategy was conducted in December 2011. It included randomized clinical trials that evaluated the use of platelet-rich plasma as coadjuvant medication to accelerate union of long bones (acute fractures, pseudoarthrosis and bone defects). The outcomes of interest for this review include bone regeneration, adverse events, costs, pain, and quality of life. The authors selected eligible studies, evaluated the methodological quality, and extracted the data. It was not possible to perform quantitative analysis of the grouped studies (meta-analyses). Two randomized prospective clinical trials were included, with a total of 148 participants. One of them compared recombinant human morphogenic bone protein-7 versus platelet-rich plasma for the treatment of pseudoarthrosis; the other evaluated the effects of three coadjuvant treatments for union of valgising tibial osteotomies (platelet-rich plasma, platelet-rich plasma plus bone marrow stromal cells, and no coadjuvant treatment). Both had low statistical power and moderate to high risk of bias. There was no conclusive evidence that sustained the use of platelet-rich plasma as a coadjuvant to aid bone regeneration of fractures, pseudoarthrosis, or bone defects.

Sepsis has high incidence and mortality rates around the world. The role of cardiac depression in myocardial dysfunction during sepsis remains to be elucidated. This review attempts to summarize our understanding of the anatomical, histopathological, and pathophysiological mechanisms behind cardiac dysfunction. Biomarkers to detect cardiac depression have been used to recognize developing problems, but the actual impact of these tools remains unclear. © 2012 Constantino Jose Fernandes Jr. and Murillo Santucci Cesar de Assuncao.

Compliance with hand hygiene is a good quality indicator for hospital patient safety programmes. Hand hygiene is a major infection control prevention intervention, but in many medical centres compliance rates are only c. 50%. Given the enormous number of hand hygiene opportunities in hospitals, direct observation to monitor compliance is very inefficient. However, technologies are emerging to obviate the need for direct observation. These new technologies for monitoring hand hygiene compliance are discussed in this article. © 2013 European Society of Clinical Microbiology and Infectious Diseases.

To propose a grading system for early hepatic graft dysfunction. A retrospective study from a single transplant center. Recipients of liver transplants from deceased donors, transplanted under the MELD system were included. Early graft dysfunction was defined by Olthoff criteria. Multiple cut-off points of post-transplant laboratory tests were used to create a grading system for early graft dysfunction. The primary outcome was 6-months grafts survival. The peak of aminotransferases during the first postoperative week correlated with graft loss. The recipients were divided into mild (aminotransferase peak >2,000IU/mL, but <3,000IU/mL); moderate (aminotransferase peak >3,000IU/mL); and severe (aminotransferase peak >3,000IU/mL + International Normalized Ratio ≥1.6 and/or bilirubin ≥ 10mg/dL in the 7th postoperative day) early allograft dysfunction. Moderate and severe early dysfunctions were independent risk factors for graft loss. Patients with mild early dysfunction presented with graft and patient survival comparable to those without graft dysfunction. However, those with moderate early graft dysfunction showed worse graft survival than those who had no graft dysfunction. Patients with severe early dysfunction had graft and patient survival rates worse than those of any other groups. Early graft dysfunction can be graded by a simple and reliable criteria based on the peak of aminotransferases during the first postoperative week. The severity of the early graft dysfunction is an independent risk factor for allograft loss. Patients with moderate early dysfunction showed worsening of graft survival. Recipients with severe dysfunction had a significantly worse prognosis for graft and patient survival.
