Title (up) Seroprevalence of dengue infection in the municipalities of Armenia, Calarca, La Tebaida and Montenegro in Quindio, 2014 Type Journal Article
Year 2017 Publication Biomedica : Revista del Instituto Nacional de Salud Abbreviated Journal Biomedica
Volume 37 Issue 1 Pages 34-41
Keywords Dengue/epidemiology; immunoglobulin G; immunoglobulin M; prevalence; public health, Colombia
Abstract INTRODUCTION: Dengue is a serious public health problem in Colombia; it is prevalent in 90% of the municipalities in Quindio. Studies on its seroprevalence are required to address public health interventions. OBJECTIVE: To establish the seroprevalence of dengue infection in neighborhoods with high incidence in the municipalities of Armenia, Calarca, La Tebaida and Montenegro, Quindio, in 2014. MATERIALS AND METHODS: We conducted a probabilistic, stratified, two-stage prevalence study. We interviewed 658 residents in the urban area of the selected municipalities. After they signed the informed consent, we took a blood sample to determine dengue IgG and IgM antibodies. RESULTS: Seroprevalence of IgG in Quindio was 89,4%; in Armenia it was 88,7%, in Calarca, 81,5%, in Montenegro, 91,8% and in La Tebaida 97,8%. IgM was 14, 2% in Quindio; in Armenia it was 11,5%, in Calarca, 13,0%, in Montenegro, 13,1% and in La Tebaida, 28,9%. CONCLUSIONS: We found a high prevalence of both IgG and IgM in the four municipalities. We had positive results for IgM in all age groups, which suggests recent infection. We also found simultaneous seropositivity for IgG and IgM (12.9%), which may indicate infection by another serotype or presence of infection in the past three months. A multisectoral approach is necessary for dengue control in Quindio.

Title (up) Severe edentulism is a major risk factor influencing stroke incidence in rural Ecuador (The Atahualpa Project) Type Journal Article
Year 2017 Publication International Journal of Stroke : Official Journal of the International Stroke Society Abbreviated Journal Int J Stroke
Volume 12 Issue 2 Pages 201-204
Keywords Adult; Comorbidity; Ecuador/epidemiology; Female; Follow-Up Studies; Humans; Hypertension/complications/epidemiology; Incidence; Male; Middle Aged; Mouth, Edentulous/complications/*epidemiology; Prospective Studies; Risk Factors; Rural Population; Severity of Illness Index; Stroke/complications/*epidemiology; Ecuador; Stroke incidence; cohort study; edentulism; stroke risk factors
Abstract Background There is no information on stroke incidence in rural areas of Latin America, where living conditions and cardiovascular risk factors are different from urban centers. Aim Using a population-based prospective cohort study design, we aimed to assess risk factors influencing stroke incidence in community-dwelling adults living in rural Ecuador. Methods First-ever strokes occurring from 1 June 2012 to 31 May 2016, in Atahualpa residents aged >/=40 years, were identified from yearly door-to-door surveys and other overlapping sources. Poisson regression models adjusted for demographics, cardiovascular risk factors, edentulism and the length of observation time per subject were used to estimate stroke incidence rate ratio as well as factors influencing such incidence. Results Of 807 stroke-free individuals prospectively enrolled in the Atahualpa Project, follow-up was achieved in 718 (89%), contributing 2,499 years of follow-up (average 3.48 +/- 0.95 years). Overall stroke incidence rate was 2.97 per 100 person-years of follow-up (95% CI: 1.73-4.2), which increased to 4.77 (95% CI: 1.61-14.1) when only persons aged >/=57 years were considered. Poisson regression models, adjusted for relevant confounders, showed that high blood pressure (IRR: 5.24; 95% CI: 2.55-7.93) and severe edentulism (IRR: 5.06; 95% CI: 2.28-7.85) were the factors independently increasing stroke incidence. Conclusions Stroke incidence in this rural setting is comparable to that reported from the developed world. Besides age and high blood pressure, severe edentulism is a major factor independently predicting incident strokes. Public awareness of the consequences of poor dental care might reduce stroke incidence in rural settings.

Title (up) Shift of microRNA profile upon glioma cell migration using patient-derived spheroids and serum-free conditions Type Journal Article
Year 2017 Publication Journal of Neuro-Oncology Abbreviated Journal J Neurooncol
Volume 132 Issue 1 Pages 45-54
Keywords Glioblastoma; MicroRNA; Migration; Serum-free; Target
Abstract Glioblastoma multiforme (GBM) is the most frequent malignant primary brain tumor. A major reason for the overall median survival being only 14.6 months is migrating tumor cells left behind after surgery. Another major reason is tumor cells having a so-called cancer stem cell phenotype being therefore resistant towards traditional chemo- and radiotherapy. A group of novel molecular targets are microRNAs (miRNAs). MiRNAs are small non-coding RNAs exerting post-transcriptional regulation of gene expression. The aim of this study was to identify differentially expressed miRNAs in migrating GBM cells using serum-free stem cell conditions. We used patient-derived GBM spheroid cultures for a novel serum-free migration assay. MiRNA expression of migrating tumor cells isolated at maximum migration speed was compared with corresponding spheroids using an OpenArray Real-Time PCR System. The miRNA profiling revealed 30 miRNAs to be differentially expressed. In total 13 miRNAs were upregulated and 17 downregulated in migrating cells compared to corresponding spheroids. The three most deregulated miRNAs, miR-1227 (up-regulated), miR-32 (down-regulated) and miR-222 (down-regulated), were experimentally overexpressed. A non-significantly increased migration rate was observed after miR-1227 overexpression. A significantly reduced migration rate was observed after miR-32 and miR-222 overexpression. In conclusion a shift in microRNA profile upon glioma cell migration was identified using an assay avoiding serum-induced migration. Both the miRNA profiling and the functional validation suggested that miR-1227 may be associated with increased migration and miR-32 and miR-222 with decreased migration. These miRNAs may represent potential novel targets in migrating glioma cells.

Title (up) Slum Upgrading and Health Equity Type Journal Article
Year 2017 Publication International Journal of Environmental Research and Public Health Abbreviated Journal Int J Environ Res Public Health
Volume 14 Issue 4 Pages
Keywords Africa; Asia; Climate Change; Employment; Environmental Health; *Health Equity; Housing; Humans; Latin America; *Poverty Areas; Socioeconomic Factors; Urban Health; Urban Population; climate change adaptation; health equity; health in all policies; housing; participation; slum upgrading; slums; social determinants of health; sustainable development goals
Abstract Informal settlement upgrading is widely recognized for enhancing shelter and promoting economic development, yet its potential to improve health equity is usually overlooked. Almost one in seven people on the planet are expected to reside in urban informal settlements, or slums, by 2030. Slum upgrading is the process of delivering place-based environmental and social improvements to the urban poor, including land tenure, housing, infrastructure, employment, health services and political and social inclusion. The processes and products of slum upgrading can address multiple environmental determinants of health. This paper reviewed urban slum upgrading evaluations from cities across Asia, Africa and Latin America and found that few captured the multiple health benefits of upgrading. With the Sustainable Development Goals (SDGs) focused on improving well-being for billions of city-dwellers, slum upgrading should be viewed as a key strategy to promote health, equitable development and reduce climate change vulnerabilities. We conclude with suggestions for how slum upgrading might more explicitly capture its health benefits, such as through the use of health impact assessment (HIA) and adopting an urban health in all policies (HiAP) framework. Urban slum upgrading must be more explicitly designed, implemented and evaluated to capture its multiple global environmental health benefits.
