    [EN] Background: Even if women have intention to breastfeed, they do not always achieve a successful breastfeeding. Aim: This study aims to analyse factors affecting breastfeeding prevalence among mothers that intended to breastfeed. Methods: This is a prospective observational study involving 401 pregnant women that intended to breastfeed (asked at the 20th week). Breastfeeding prevalence was evaluated in reference to health-related, socio-cultural factors and healthcare professionals' interventions at 1 month, 6 months and 12 months after birth. Data were analysed using descriptive statistical methods, bivariate logistic regression and multivariate logistic regression modelling. Results: Independent factors negatively affecting breastfeeding prevalence related to mothers' and newborns' health parameters and birth characteristics included smoking during pregnancy, anaemia and use of analgesia during labour. Regarding sociocultural parameters, being an immigrant, higher education level, intention to breastfeed before pregnancy, comfort with public breastfeeding and bedsharing were positively linked to breastfeeding, while teat or pacifier use in the first week was negatively linked. Regarding healthcare professionals' practices, mother and father/partner antenatal education course attendance and exclusive breastfeeding at the hospital were positively associated with breastfeeding. Conclusion: Breastfeeding is a very complex phenomenon affected by multiple and diverse variables. Physiological factors only affect the short term (1st month), while middle and long term BF affecting variables are mainly identical and include mostly socio-cultural factors and also BF related practices, especially in the first days after birth. These data should help to develop more effective breastfeeding promotion strategies.Funding GGTM has received the grant OSIBB18/024 from BIOEF (Fundacion Vasca de Innovacion e Investigacion Sanitarias) .

    Microfinance crisis: identifying problems

    Get PDF
    RESUMEN. La actividad en el sector de las microfinanzas ha crecido de manera exponencial en los últimos años. En este periodo han existido grandes éxitos, pero también bastantes fracasos, los cuales han tenido menor repercusión. La literatura se ha centrado principalmente en los logros del sector y las buenas prácticas que han emergido de sus experiencias. Sin embargo, poco se ha tratado sobre los fracasos institucionales y menos sobre las estrategias que siguieron las entidades supervivientes a esas crisis. A pesar de la escasa producción científica sobre los fracasos de estas instituciones, no cabe duda que analizar los factores que influyen en las crisis microfinancieras puede ser muy útil para predecir futuras dificultades y, de esta manera, poder aplicar los mitigadores oportunos. Realizando un análisis empírico con datos de panel, para una muestra de entidades a nivel internacional, el trabajo se ocupará de analizar cuáles son los factores internos y externos más relevantes que explican las dificultades de las entidades del sector de las microfinanzas.ABSTRACT. The activity in the microfinance sector has grown exponentially in recent years. In this period there have been great successes, but also many failures, which have had less impact. The literature has focused mainly on the achievements of the sector and the best practices that have emerged from their experiences. However, there is little research about microfinance crises. Despite the lack of scientific literature on failures of microfinance institutions, the analysis of the factors of microfinance crises could be very useful in predicting future difficulties and failures. These results could be very helpful in applying the appropriate measures in order to reduce these failures. We propose an empirical analysis with panel data for a sample of international microfinance institutions. We analyze the most important factors, internal and external, which explain the difficulties of microfinance institutions

    Research facilities and highlights at the Centro Nacional de Aceleradores (CNA)

    Get PDF
    The Centro Nacional de Aceleradores is a user-oriented accelerator facility in Seville, Spain. Its main facilities are a 3 MV tandem accelerator, an 18 MeV proton Cyclotron, a tandetron used for AMS, a compact accelerator used for radiocarbon measurements, a 60Co irradiator and a PET/CT scanner. The technical specifications and research applications of these facilities are described. A neutron beam line associated to a charged pulsed beam in the tandem allows for time of flight measurements which determine the neutron energy. The use of an adequate stripper gas in the AMS tandetron permits to measure heavy radionuclides with very low detection levels, allowing to perform environmental studies using these radionuclides as tracers. The use of the microbeam in the tandem accelerator allows to apply the ion beam-induced current technique to investigate the spectroscopic properties and radiation hardness of different semiconductor detectors.European Union, H2020-847594, H2020-654002, H2020-847552, H2020-847594Ministry of Science RTI2018-098117-B-C21, RTC-2017-6369-3, EQC2018-004193-P, EQC2018-004095-P, EQC2018-004166- P, PGC2018-094546-B-I00Junta de Andalucía FEDER US-1261006, US-1263369, P18-RT-190

    Dipeptidyl-Peptidase IV Activity Is Correlated with Colorectal Cancer Prognosis

    Background Dipeptidyl-peptidase IV (EC 3.4.14.5) (DPPIV) is a serine peptidase involved in cell differentiation, adhesion, immune modulation and apoptosis, functions that control neoplastic transformation. Previous studies have demonstrated altered expression and activity of tissue and circulating DPPIV in several cancers and proposed its potential usefulness for early diagnosis in colorectal cancer (CRC). Methods and principal findings The activity and mRNA and protein expression of DPPIV was prospectively analyzed in adenocarcinomas, adenomas, uninvolved colorectal mucosa and plasma from 116 CRC patients by fluorimetric, quantitative RT-PCR and immunohistochemical methods. Results were correlated with the most important classic pathological data related to aggressiveness and with 5-year survival rates. Results showed that: 1) mRNA levels and activity of DPPIV increased in colorectal neoplasms (Kruskal-Wallis test, p<0.01); 2) Both adenomas and CRCs displayed positive cytoplasmic immunostaining with luminal membrane reinforcement; 3) Plasmatic DPPIV activity was lower in CRC patients than in healthy subjects (Mann-U test, p<0.01); 4) Plasmatic DPPIV activity was associated with worse overall and disease-free survivals (log-rank p<0.01, Cox analysis p<0.01). Conclusion/significance 1) Up-regulation of DPPIV in colorectal tumors suggests a role for this enzyme in the neoplastic transformation of colorectal tissues. This finding opens the possibility for new therapeutic targets in these patients. 2) Plasmatic DPPIV is an independent prognostic factor in survival of CRC patients. The determination of DPPIV activity levels in the plasma may be a safe, minimally invasive and inexpensive way to define the aggressiveness of CRC in daily practice.This work was supported by grants from the Basque Government (IT8-11/13), the University of the Basque Country UPV/EHU (UFI 11/44), and the Gangoiti Barrera Foundation.

    Overexpression of canonical prefoldin associates with the risk of mortality and metastasis in non-small cell lung cancer

    Get PDF
    Canonical prefoldin is a protein cochaperone composed of six di erent subunits (PFDN1 to 6). PFDN1 overexpression promotes epithelial–mesenchymal transition (EMT) and increases the growth of xenograft lung cancer (LC) cell lines. We investigated whether this putative involvement of canonical PFDN in LC translates into the clinic. First, the mRNA expression of 518 non-small cell LC (NSCLC) cases from The Cancer Genome Atlas (TCGA) database was evaluated. Patients with PFDN1 overexpression had lower overall survival (OS; 45 vs. 86 months; p = 0.034). We then assessed the impact of PFDN expression on outcome in 58 NSCLC patients with available tumor tissue samples. PFDN1, 3, and 5 overexpression were found in 38% (n = 22), 53% (n = 31), and 41% (n = 24) of tumor samples. PFDN1, 3, and 5 overexpression were significantly associated with lower OS, lower disease-free survival (DFS), and lower distant metastasis-free survival (DMFS) for PFDN1 and 3 with a trend for PFDN5. In multivariate analysis, PFDN5 retained significance for OS (hazard ratio (HR) 2.56; p = 0.007) and PFDN1 for DFS (HR 2.53; p = 0.010) and marginally for DMFS (HR 2.32; p = 0.053). Our results indicate that protein response markers, such as PFDN1, 3, and 5, may complement mRNA signatures and be useful for determining the most appropriate therapy for NSCLC patients

    A UHPLC-Mass Spectrometry View of Human Melanocytic Cells Uncovers Potential Lipid Biomarkers of Melanoma

    Melanoma is the deadliest form of skin cancer due to its ability to colonize distant sites and initiate metastasis. Although these processes largely depend on the lipid-based cell membrane scaffold, our understanding of the melanoma lipid phenotype lags behind most other aspects of this tumor cell. Here, we examined a panel of normal human epidermal and nevus melanocytes and primary and metastatic melanoma cell lines to determine whether distinctive cell-intrinsic lipidomes can discern non-neoplastic from neoplastic melanocytes and define their metastatic potential. Lipidome profiles were obtained by UHPLC-ESI mass-spectrometry, and differences in the signatures were analyzed by multivariate statistical analyses. Significant and highly specific changes in more than 30 lipid species were annotated in the initiation of melanoma, whereas less numerous changes were associated with melanoma progression and the non-malignant transformation of nevus melanocytes. Notably, the “malignancy lipid signature” features marked drops in pivotal membrane lipids, like sphingomyelins, and aberrant elevation of ether-type lipids and phosphatidylglycerol and phosphatidylinositol variants, suggesting a previously undefined remodeling of sphingolipid and glycerophospholipid metabolism. Besides broadening the molecular definition of this neoplasm, the different lipid profiles identified may help improve the clinical diagnosis/prognosis and facilitate therapeutic interventions for cutaneous melanoma.This research was funded in part by grants from the Ministry of Economy; Industry and Competitiveness (RTC-2015-3693-1); Ministry of Science and Innovation (RTI-2018-095134-B-I00); Basque Government (IT971-16; IT1162-19; KK2016-036; KK2017-041 and KK2018-00090) and UPV/EHU (GIU17/066)
