RESUMO

BACKGROUND: In testicular cancer determination of clinical stage and recommendation of therapeutic strategy after inguinal orchiectomy are based on primary imaging by CT-scan of the chest and CT- or MRI-abdomen. It has not been investigated so far whether the imaging should be performed before or after primary testicular surgery. Staging before surgery means exposing all patients to CT radiation irrespective of ensured histologic malignancy while postoperative staging could pose a risk in biased clinical decision making by increased presence of unspecific lymph node enlargement caused by postsurgical effects. Therefore, we aimed to investigate the association between the timing of initial staging and occurrence of unspecific lymph node enlargement and adjuvant therapies after inguinal orchiectomy. METHODS: We retrospectively evaluated clinical and radiological data from 236 patients who had undergone inguinal orchiectomy for testicular cancer at our department. Statistical analysis was performed to determine whether the occurrence of unspecific lymph node enlargement or the rate of adjuvant therapies were influenced by timing of initial staging (preoperative vs. postoperative). RESULTS: The postoperative imaging cohort showed significant more inguinal, pelvic and retroperitoneal unspecific lymph node enlargement than the preoperative imaging cohort. Simultaneous occurrence of inguinal or pelvic lymph node enlargement together with retroperitoneal enlargements could only be found in the postoperative imaging cohort. No difference regarding adjuvant therapies could be found. CONCLUSIONS: Timing of imaging affects the detection rate of unspecific lymph node enlargements but does not show a significant effect on the rate of adjuvant therapies.

RESUMO

The American Physical Therapy Association's Vision Statement of 2013 asserts that physical therapists optimize movement in order to improve the human experience. In accordance with this vision, physical therapists strive to be recognized as experts in movement analysis. However, there continues to be no accepted method to conduct movement analysis, nor an agreement of key terminology to describe movement observations. As a result, the Academy of Neurologic Physical Therapy organized a task force that was charged with advancing the state of practice with respect to these issues, including the development of a proposed method for movement analysis of tasks. This paper presents the work of the Task Force, which includes (1) development of a method for conducting movement analysis within the context of the movement continuum during 6 core tasks (sitting, sit to stand, standing, walking, step up/down, and reach/grasp/manipulate); (2) glossary of movement constructs that can provide a common language for movement analysis across a range of tasks: symmetry, speed, amplitude, alignment, verticality, stability, smoothness, sequencing, timing, accuracy, and symptom provocation; and (3) recommendations for task and environmental variations that can be systematically applied. The expectation is that this systematic framework and accompanying terminology will be easily adapted to additional patient or client-specific tasks, contribute to development of movement system diagnostic labels, and ultimately improve consistency across patient/client examination, evaluation, and intervention for the physical therapy profession. Next steps should include validation of this framework across patient/client groups and settings.

RESUMO

INTRODUCTION: Treatment strategy for inoperable and metastatic urothelial carcinoma (mUC) has been revolutionized by the introduction of programmed cell death protein 1 (PD-1) and programmed cell death protein ligand (PD-L1) antibodies. During the last 3 decades treatment options were limited to chemotherapy, making further treatment of patients whose disease progressed under ongoing therapy or who were ineligible to receive cytotoxic therapy in the first place, nearly impossible. EVIDENCE ACQUISITION: Five antibodies including pembrolizumab (PD-L1 antibody), atezolizumab (PD-1 antibody), nivolumab (PD-1 antibody), avelumab and durvalumab (PD-L1 antibodies) have been approved in the treatment of advanced urothelial carcinoma in first- and second-line treatment setting. The objective of this review was to examine and compare the different cohorts and to discuss the quality of the respective studies in order to set up selection criteria for clinical decision making. EVIDENCE SYNTHESIS: So far pembrolizumab and atezolizumab have demonstrated overall survival (OS) benefit in phase II studies and have shown superiority over standard chemotherapy in phase III studies which has granted them approval in first and second-line treatment setting. Improved OS and durable responses were also seen in phase Ib/II non-randomized, single-arm trials conducted with nivolumab, avelumab and durvalumab and granting accelerated approval for second-line treatment. The huge advantage of immunotherapy and one of the reasons for its overall recognition is its good tolerability profile especially in comparison to chemotherapy. CONCLUSIONS: Pembrolizumab has to be recommended in second-line therapy due to reporting in a phase III trial and OS survival benefit compared to chemotherapy control group. In cisplatin-eligible and treatment-naïve patients with visceral or liver metastases data also slightly favors pembrolizumab rather than atezolizumab.

RESUMO

Vascularization is essential for bone development, fracture healing, and bone tissue engineering. We have previously described that coculture of primary human osteoblasts (hOBs) and human umbilical vein endothelial cells (HUVECs) improves differentiation of both cell types. Investigating the role of microRNAs (miRNAs) in this system, we found that miR-126 is highly upregulated in hOBs following coculturing with HUVECs. In this study we performed miR-126 gain-of-function and loss-of-function experiments in hOBs followed by microarray analysis in order to identify targets of miR-126. The transcript cluster IDs were sieved by applying cut-off criteria and by selecting transcripts which were upregulated following miR-126 downregulation and vice versa. The calmodulin regulated spectrin associated protein 1 (CAMSAP1) mRNA was confirmed to be differentially regulated by miR-126. Using the luciferase reporter assay it was demonstrated that CAMSAP1 is directly targeted by miR-126. In this study, we show that miR-126 and CAMSAP1 directly interact in hOBs. This finding has potential implications for tissue engineering applications. J. Cell. Biochem. 118: 1756-1763, 2017. © 2016 Wiley Periodicals, Inc.
