  Abstract The present study analyzed outcomes of surgery followed by concomitant chemoradiotherapy (CCRT) with temozolomide (TMZ) in patients with newly diagnosed glioblastoma (GBM) at a single institution. Outcomes were retrospectively reviewed in 252 consecutive patients with newly diagnosed GBM who underwent surgery followed by CCRT with TMZ at the authors' institution between 2005 and 2013. At initial operation, 126 (50.0%), 55 (21.8%), 45 (17.9%), and 26 (10.3%) patients underwent gross total resection (GTR), subtotal resection, partial resection (PR), and biopsy, respectively. Their median overall survival (OS) was 20.8 months (95% confidence interval [CI] 17.7-23.9 months) and their median progression-free survival was 12.7 months (95% CI 11.2-14.2 months). The O-methylguanine-DNA methyltransferase (MGMT) promoter was methylated in 78 (34.1%) of the 229 patients assayed, and an isocitrate dehydrogenase 1 mutation was detected in 7 (6.6%) of the 106 patients analyzed. Univariate analyses showed that patient age, involvement of eloquent areas, involvement of the subventricular zone, presence of leptomeningeal seeding, Karnofsky Performance Status, extent of resection (EOR), MGMT promoter methylation, and presence of an oligodendroglioma component were prognostic of OS. Multivariate analysis showed that age, involvement of eloquent areas, presence of leptomeningeal seeding, EOR, and MGMT promoter methylation were significantly predictive of survival. OS in patients with GBM who undergo surgery followed by CCRT with TMZ is enhanced by complete resection. Other factors significantly prognostic of OS include that age, involvement of eloquent areas, presence of leptomeningeal seeding, and MGMT promoter methylation.

  Title Targeting Deubiquitinating Enzymes in Glioblastoma Multiforme: Expectations and Challenges Type Journal Article
  Year 2017 Publication (down) Medicinal Research Reviews Abbreviated Journal Med Res Rev  
  Volume 37 Issue 3 Pages 627-661  
  Keywords Animals; Carcinogenesis/pathology; Deubiquitinating Enzymes/antagonists & inhibitors/*metabolism; Enzyme Inhibitors/pharmacology; Glioblastoma/*enzymology/*therapy; Humans; *Molecular Targeted Therapy; Neoplastic Stem Cells/drug effects/pathology; DUB inhibitor; DUBs; glioblastoma; glioma stem cells; proteasome  
  Abstract Glioblastoma (GBM) is regarded as the most common primary intracranial neoplasm. Despite standard treatment with tumor resection and radiochemotherapy, the outcome remains gloomy. It is evident that a combination of oncogenic gain of function and tumor-suppressive loss of function has been attributed to glioma initiation and progression. The ubiquitin-proteasome system is a well-orchestrated system that controls the fate of most proteins by striking a dynamic balance between ubiquitination and deubiquitination of substrates, having a profound influence on the modulation of oncoproteins, tumor suppressors, and cellular signaling pathways. In recent years, deubiquitinating enzymes (DUBs) have emerged as potential anti-cancer targets due to their targeting several key proteins involved in the regulation of tumorigenesis, apoptosis, senescence, and autophagy. This review attempts to summarize recent studies of GBM-associated DUBs, their roles in various cellular processes, and discuss the relation between DUBs deregulation and gliomagenesis, especially how DUBs regulate glioma stem cells pluripotency, microenvironment, and resistance of radiation and chemotherapy through core stem-cell transcriptional factors. We also review recent achievements and progress in the development of potent and selective reversible inhibitors of DUBs, and attempted to find a potential GBM treatment by DUBs intervention.

  Title Determinants of perceived insufficient milk among new mothers in Leon, Nicaragua Type Journal Article
  Year 2017 Publication (down) Maternal & Child Nutrition Abbreviated Journal Matern Child Nutr  
  Volume 13 Issue 3 Pages  
  Keywords Baby-friendly hospital initiative; breastfeeding; breastfeeding promotion; breastfeeding support; perceived insufficient milk; qualitative methods  
  Abstract Breastfeeding has been shown to improve maternal and child health. In Nicaragua, the primary risk of death and disability-adjusted life years among children under 5 years of age is suboptimal breastfeeding. Although the Nicaraguan Ministry of Health promotes exclusive breastfeeding from within the first half hour through the first 6 months of life, less than a third of children in the country under 6 months of age are exclusively breastfed. As part of a larger, mixed-methods study, 21 semi-structured, in-depth interviews were conducted with new mothers recruited from three primary health centers between June and August 2015 in order to identify the social, cultural, and structural factors that contribute to infant feeding practices and the discrepancy between recommendations and practices among mothers who delivered at an urban public hospital in Leon, Nicaragua. Audio recordings were transcribed verbatim, and interview transcripts were coded and analyzed by a three-member team using a grounded theory approach. Findings highlight a widespread perception of insufficient milk among mothers that influenced early cessation of exclusive breastfeeding and other infant feeding practices. This perception stemmed from anxiety about meeting infant nutritional needs and infant satiety, anxiety about maternal nutrition, advice from and role modeling of family members about mixed feeding, and perceived infant feeding norms. Results suggest that support modeled after the 10 steps of the Baby-friendly Hospital Initiative as well as strengthened policy-level support are needed. Community interventions that address cultural and structural barriers to improve breastfeeding practices may also help to increase breastfeeding rates.

  Title Prospective, randomized study of long-term hemodialysis catheter removal versus guidewire exchange to treat catheter-related bloodstream infection Type Randomized Controlled Trial
  Year 2017 Publication (down) Journal of Vascular Surgery Abbreviated Journal J Vasc Surg  
  Volume 66 Issue 5 Pages 1427-1431.e1

  Abstract BACKGROUND: Long-term (tunneled cuffed) hemodialysis catheters are frequently used vascular access in renal failure patients. Catheter-related bloodstream infection (CRBSI) is a common complication of long-term hemodialysis catheters, with severe morbidities and high risk of mortality. Management of CRBSI by systemic antibiotics while keeping the catheter in place is not effective. Among the different modalities of CRBSI management are catheter removal (CR) and guidewire exchange (GE) of the catheter. The aim of this study was to compare the clinical outcome of CRBSI treated with two different strategies: GE vs CR with new catheter insertion 3 to 7 days later. METHODS: This prospective randomized study analyzed the outcomes of all cases of long-term hemodialysis CRBSI during a 5-year period. The catheter infection-free survival time was analyzed in the two groups of patients (GE group, 339 patients; CR group, 339 patients). Three weeks of systemic antibiotic therapy was used according to culture in both groups. The catheter infection-free survival was analyzed using Kaplan-Meier analysis. RESULTS: No statistically significant difference was found in catheter infection-free survival time for GE and CR groups (P = .69), which is not affected by age, sex, presence of diabetes mellitus, or type of causative organism. CONCLUSIONS: Our study did not demonstrate a difference in the clinical outcome of CRBSI treated with GE or CR with new catheter insertion 3 to 7 days later. However, guidewire catheter exchange saves veins for future access, reduces the cost and number of procedures, and avoids complications of new venipuncture.
