Ecological typologies of large areas. An application in the Mediterranean Sea

One approach to identifying and mapping the state of marine biophysical conditions is the identification of large-scale ecological units for which conditions are similar and the strategies of management may also be similar. Because biological processes are difficult to directly record over large areas, abiotic characteristics are used as surrogate parameters. In this work, the Mediterranean Sea was classified into homogeneous spatial areas based on abiotic variables. Eight parameters were selected based on salinity, sea surface temperature, photosynthetically active radiation, sea-wave heights and depth variables. The parameters were gathered in grid points of 0.5° spatial resolution in the open sea and 0.125° in coastal areas. The typologies were obtained by data mining the eight parameters throughout the Mediterranean and combining two clustering techniques: self-organizing maps and the k-means algorithm. The result is a division of the Mediterranean Sea into seven typologies. For these typologies, the classification recognizes differences in temperature, salinity and radiation. In addition, it separates coastal from deep areas. The influence of river discharges and the entrance of water from other seas are also reflected. These results are consistent with the ecological requirements of the five studied seagrasses (Posidonia oceanica, Zostera marina, Zostera noltei, Cymodocea nodosa, Halophila stipulacea), supporting the suitability of the resulting classification and the proposed methodology. The approach thus provides a tool for the sustainable management of large marine areas and the ability to address not only present threats but also future conditions, such as climate change.This research is included in the framework of the CoCoNET project (Towards COast to COast NETworks of marine protected areas (from the shore to the high and deep sea), coupled with sea-based wind energy potential) and is funded by the National Plan for Research in Science and Technological Innovation from the Spanish Government 2013–2016 (Ministry of Economy and Competitiveness) (C3N project CTM2015-68244-R) and co-financed by the European Regional Development's funds (FEDER).

Prevalencia de sintomáticos respiratorios, de infección y enfermedad tuberculosa y factores asociados: estudio basado en población, Mitú, Vaupés, 2001.

A cross sectional survey on TB epidemiological characteristics was carried out in Mitú (Vaupes, Colombia) with the aim of measuring the prevalence of TB cases, the prevalence of TB suspected cases, the coverage with BCG vaccine and the prevalence of infection with Mycobacterium tuberculosis. One hundred and sixty five (165) households were included in the survey using a randomized cluster sampling design (n=20 clusters) which yielded a sample size of 972 subjects. The prevalence of TB suspect cases was 3.6% (C.I.95% 2.6-4.9%); coverage with BCG vaccine was 94%. Vaccinated people had a lower chance of being a TB suspected case (OR=0.37 C.I.95% 0.15-0.95). TB prevalence was 1.4%. People vaccinated with BCG had a lower chance of having been a TB case (OR=3.3 C.I.95% 1.0-14). These data recommend that 10% of people with respiratory symptoms be screened for in the National Control Program,and that the results be reviewed with surveys based at health centers. The data also reinforce the need for better vaccination coverages with BCG in high endemic areas.Se realizó una encuesta transversal en Mitú (Vaupés), un área de alta endemicidad para tuberculosis, con el objetivo de medir la proporción de sintomáticos respiratorios en la población, la prevalencia de casos de tuberculosis, de vacunación con BCG y la frecuencia de infección con Mycobacterium tuberculosis. Se incluyeron en el estudio 165 viviendas elegidas aleatoriamente por medio de un muestreo por conglomerados (n=20 conglomerados) y se encuestaron 972 personas. La prevalencia de sintomáticos respiratorios fue de 3,6% (IC95% 2,6-4,9%) mientras que la de vacunación con BCG fue de 94%. Las personas vacunadas tenían una prevalencia menor de síntomas respiratorios (OR=0,37; IC95% 0,15-0,95). La prevalencia de tuberculosis fue de 1,4% y se encontró que las personas con cicatriz de BCG tenían tres veces menos probabilidad de haber tenido tuberculosis (OR=3,3; IC95% 1,0-14). Nuestros hallazgos sugieren que la proporción de sintomáticos respiratorios que el Programa Control de Tuberculosis tiene como meta de búsqueda (10%) debe ser actualizada mediante una investigación operativa nacional. Asimismo, refuerzan la necesidad de lograr buenas coberturas de vacunación con BCG en poblaciones endémicas

Is There Such a Thing as a Genuine Cancer Stem Cell Marker? Perspectives from the Gut, the Brain and the Dental Pulp

The conversion of healthy stem cells into cancer stem cells (CSCs) is believed to underlie tumor relapse after surgical removal and fuel tumor growth and invasiveness. CSCs often arise from the malignant transformation of resident multipotent stem cells, which are present in most human tissues. Some organs, such as the gut and the brain, can give rise to very aggressive types of cancers, contrary to the dental pulp, which is a tissue with a very remarkable resistance to oncogenesis. In this review, we focus on the similarities and differences between gut, brain and dental pulp stem cells and their related CSCs, placing a particular emphasis on both their shared and distinctive cell markers, including the expression of pluripotency core factors. We discuss some of their similarities and differences with regard to oncogenic signaling, telomerase activity and their intrinsic propensity to degenerate to CSCs. We also explore the characteristics of the events and mutations leading to malignant transformation in each case. Importantly, healthy dental pulp stem cells (DPSCs) share a great deal of features with many of the so far reported CSC phenotypes found in malignant neoplasms. However, there exist literally no reports about the contribution of DPSCs to malignant tumors. This raises the question about the particularities of the dental pulp and what specific barriers to malignancy might be present in the case of this tissue. These notable differences warrant further research to decipher the singular properties of DPSCs that make them resistant to transformation, and to unravel new therapeutic targets to treat deadly tumors.This work has been financed by The University of The Basque Country (UPV/EHU): Grant number GIU16/66, UFI 11/44, COLAB19/03 and IKERTU-2020.0155 (to F.U), the Basque Government/Eusko Jaurkaritza: ELKARTEK KK-2019/00093 (to U.F.), and MINECO “Ramón y Cajal” program RYC-2013-13450 and MINECO PID2019-104766RB-C21 (to P.J.R.).

How protective is cervical cancer screening against cervical cancer mortality in developing countries? The Colombian case

<p>Abstract</p> <p>Background</p> <p>Cervical cancer is one of the top causes of cancer morbidity and mortality in Colombia despite the existence of a national preventive program. Screening coverage with cervical cytology does not explain the lack of success of the program in reducing incidence and mortality rates by cervical cancer. To address this problem an ecological analysis, at department level, was carried out in Colombia to assess the relationship between cervical screening characteristics and cervical cancer mortality rates.</p> <p>Methods</p> <p>Mortality rates by cervical cancer were estimated at the department level for the period 2000-2005. Levels of mortality rates were compared to cervical screening coverage and other characteristics of the program. A Poisson regression was used to estimate the effect of different dimensions of program performance on mortality by cervical cancer.</p> <p>Results</p> <p>Screening coverage ranged from 28.7% to 65.6% by department but increases on this variable were not related to decreases in mortality rates. A significant reduction in mortality was found in departments where a higher proportion of women looked for medical advice when abnormal findings were reported in Pap smears. Geographic areas where a higher proportion of women lack health insurance had higher rates of mortality by cervical cancer.</p> <p>Conclusions</p> <p>These results suggest that coverage is not adequate to prevent mortality due to cervical cancer if women with abnormal results are not provided with adequate follow up and treatment. The role of different dimensions of health care such as insurance coverage, quality of care, and barriers for accessing health care needs to be evaluated and addressed in future studies.</p

Observation of associated near-side and away-side long-range correlations in √sNN=5.02 TeV proton-lead collisions with the ATLAS detector

Two-particle correlations in relative azimuthal angle (Δϕ) and pseudorapidity (Δη) are measured in √sNN=5.02  TeV p+Pb collisions using the ATLAS detector at the LHC. The measurements are performed using approximately 1  μb-1 of data as a function of transverse momentum (pT) and the transverse energy (ΣETPb) summed over 3.1<η<4.9 in the direction of the Pb beam. The correlation function, constructed from charged particles, exhibits a long-range (2<|Δη|<5) “near-side” (Δϕ∼0) correlation that grows rapidly with increasing ΣETPb. A long-range “away-side” (Δϕ∼π) correlation, obtained by subtracting the expected contributions from recoiling dijets and other sources estimated using events with small ΣETPb, is found to match the near-side correlation in magnitude, shape (in Δη and Δϕ) and ΣETPb dependence. The resultant Δϕ correlation is approximately symmetric about π/2, and is consistent with a dominant cos⁡2Δϕ modulation for all ΣETPb ranges and particle pT
