  Title Percentage of mesenchymal stem cells in high-grade glioma tumor samples correlates with patient survival Type Journal Article
  Year 2017 Publication Neuro-Oncology Abbreviated Journal Neuro Oncol  
  Volume 19 Issue 5 Pages (down) 660-668  
  Keywords *glioblastoma; *mesenchymal stem cells; *microenvironment; *prognosis  
  Abstract Background: Human mesenchymal stem cells (hMSCs) have been shown to reside as stromal cells in human gliomas as glioma-associated hMSCs (GA-hMSCs), but their biological role remains unclear. Because recent evidence indicates that GA-hMSCs drive tumor cell proliferation and stemness, we hypothesized that a higher percentage of GA-hMSCs in tumors predicts poor patient prognosis. Method: We determined the percentage of cells coexpressing GA-hMSC markers CD105+/CD73+/CD90+ from patients with newly diagnosed high-grade glioma and analyzed the association between this percentage and overall survival (OS) in 3 independent cohorts: fresh surgical glioblastoma specimens (cohort 1, N = 9), cultured tumor specimens at passage 3 (cohort 2, N = 28), and The Cancer Genome Atlas (TCGA) database. Results: In all cohorts, patient OS correlated with the percentages of GA-hMSCs in tumors. For cohort 1, the median OS of patients with tumors with a low percentage of triple-positive cells was 46 months, and for tumors with a high percentage of triple-positive cells, it was 12 months (hazard ratio [HR] = 0.24; 95% CI: 0.02-0.5, P = .02). For cohort 2, the median OS of patients with tumors with a low percentage of GA-hMSCs was 66 months, and for tumors with a high percentage, it was 11 months (HR = 0.38; 95% CI: 0.13-0.9, P = .04). In the database of TCGA, the median OS times in patients with high and low coexpression levels of CD105/CD73/CD90 were 8.4 months and 13.1 months (HR = 0.4; 95% CI: 0.1-0.88; P = .04), respectively. Conclusions: The percentage of GA-MSCs inversely correlates with OS, suggesting a role for GA-MSCs in promoting aggressive behavior of gliomas.

  Title Mechanisms regulating radiosensitivity of glioma stem cells Type Journal Article
  Year 2017 Publication Neoplasma Abbreviated Journal Neoplasma  
  Volume 64 Issue 5 Pages (down) 655-665  
  Keywords glioma stem cells; radiosensitivity signaling pathways.  
  Abstract Malignant glioblastoma (GBM) has become a very common and difficult brain tumor given its low cure rate and high recurrence rate. GBMs are resistant to treatments because glioma stem cells (GSCs)/glioma-initiating cells (GICs), a specific subpopulation of GBM, possess properties of tumor stem cells, such as unlimited proficiency, self-renewal, differentiation and resistance to chemotherapy and radiotherapy, and exhibit a very strong DNA repair capability. Radiotherapy has become a preponderant treatment, and researchers have found many significant tumor microenvironmental factors and valuable signaling pathways regulating the GSC radioresistance, including NOTCH, Wnt/beta-catenin, Hedgehog, STAT3, and PI3K/AKT/mTOR. Therefore, we seek to boost GSC radiosensitivity through activating or inactivating pathways alone or together to eliminate the likely source of glioma and prolong survival of patients.

  Abstract INTRODUCTION: Worldwide, burns are responsible for more than 300,000 deaths annually; infection is a major cause of morbidity and mortality in these patients. Early identification and treatment of infection improves outcome. Toward this end it's necessary to identify the institutions flora and organisms that most frequently produces infection. OBJECTIVES: To characterize infections developed by burn patients hospitalized at the University Hospital of Santander (HUS). METHODOLOGY: Burn patients hospitalized in the HUS from January 1 to December 2014 were followed. Medical information regarding infections, laboratory and pathology reports were obtained. Statistical analysis with measures of central tendency, proportions, global and specific incidence density plus overall and specific incidence was obtained. For the microbiological profile proportions were established. RESULTS: 402 burn patients were included, 234 (58.2%) men and 168 (41.8%) women, aged between 6 days and 83 years, median 12.5 years. The burn agents include scald (52.5%), fire (10.0%), gasoline (9.2%), electricity (7.5%), among others. Burn area ranged from 1% to 80% TBS. Cumulative mortality was 1.5%. 27.8% of burned patients had one or more infections. Identified infections include folliculitis (27.0%), urinary tract infection (19.0%), infection of the burn wound (10.4%), pneumonia (8.6%), Central venous catheter (7.4%), bloodstream infection (7.4%) and skin grafts infection (4.3%) among others. Bacteria were responsible for 88.5% of the cases and fungi 11.5%. The most frequently isolated germs were P. aeruginosa, A. baumannii, E. coli, S. aureus and K. pneumoniae. Most gram-negative bacteria were sensitive to Amikacin, gram positive bacteria were sensitive to multiple antibiotics. CONCLUSION: Burns is a severe trauma that occurs in adult and pediatric patients, has several causative agents and can compromise the patient's life. The burned patient is at risk for a variety of infections. According to the type of infection it is possible to infer the most common causative organisms and their antibiotic sensitivity/resistance which allow a directed early empiric treatment.

  Title Degree of malnutrition and its relationship with major structural and eating factors in Honduran preschool population. Prevalence of breastfeeding Type Journal Article
  Year 2017 Publication Nutricion Hospitalaria Abbreviated Journal Nutr Hosp  
  Volume 34 Issue 3 Pages (down) 639-646  
  Keywords *Honduras; *Child malnutrition; *Breastfeeding  
  Abstract Introduction: Child malnutrition remains a serious public health problem in Honduras, with a national prevalence according to the World Health Organization (WHO) reference values of 29% in children under fi ve. In addition, the average chronic malnutrition in the region amounts to 80% in poor and indigenous communities, making Honduras the second country in Central America with the highest incidence of chronic malnutrition. Another problem of the region is the early cessation of exclusive breastfeeding: only 29.7% of children were exclusively breastfed until they were six months. Therefore, the study seeks to understand, identify and quantify the situation determinants and provide information for the design of public policies. Material and method:: The study consisted of a cross-sectional descriptive anthropometric assessment in which the nutritional status and the prevalence of undernourishment, malnutrition and malnutrition in 141 children aged between six months and fi ve years, belonging to urban and rural regions of the country, were analyzed, as well as assessing the prevalence of breastfeeding in fi ve Honduran departments (Intibuca, Lempira, Atlantida, Olancho and Francisco Morazan). Results and conclusion: When making the analysis by departments, differences regarding nutritional status and breastfeeding were observed between urban and rural areas, the latter being doubled in the case of chronic malnutrition and underweight, with percentages of 14.6% in urban areas versus28.8% in rural areas, and 4.6% in urban areas compared to 9% in rural areas, respectively. However, with respect to acute malnutrition and overweight in both regions, similar values were observed, above 1.1% for acute and 14% for overweight malnutrition. In relation to exclusive breastfeeding for six months, the departments of Olancho and Lempira maintained it for two years, with a percentage distribution of 80% and 48%, respectively. It must be noted that 36% of mothers did not provide breastfeeding, with the highest rate (15%) in the department of Francisco Morazan.
