In Respiratory Syncytial Virus infection, the early identification of infants at risk for severe disease in order to potentially decrease morbidity could be considered a major goal. Current guidelines recommend only clinical observation for this purpose in infants without known comorbidities. However, recent evidence shows that the presence of pulmonary hypertension in this population is a relevant risk factor for the development of a severe illness, even in healthy infants. The determination of plasmatic NT-proBNP levels could help to identify those cases that benefit of echocardiographic screening to detect pulmonary hypertension in this population during hospitalization.

The fifth-century BC site of Casas del Turuñuelo in south-western Spain provides unique information on the production and ritual consumption of textiles in Iron Age Iberia. Casas del Turuñuelo was a rural estate centre that was intentionally burned following a banquet and the sacrifice of over 50 domestic animals. Among the offerings are the earliest-known wool textiles and twill weaves on the Iberian Peninsula. This assemblage represents the most diverse textile collection found in the region to date, and provides the first glimpse of the role of textiles in the sacrificial economy of Iberia, and in prehistoric Europe more widely.

Estudiamos el imperialismo incaico en el contexto de las formaciones socioterritoriales del Colesuyu durante la época prehispánica tardía (siglos quince y dieciséis). Por su poblamiento con alto grado de multietnicidad e imbricación socioterritorial, además de su heterogeneidad biogeográfica entre el Pacífico y el Altiplano, esta región de los Valles Occidentales de los Andes Centro-Sur planteó un reto geopolítico para su integración imperial. Nos interesamos aquí por el caso de los Altos de Arica, que los archivos coloniales describen como un espacio multiétnico, con complejos sistemas de asentamiento interdigitados, extendidos entre el altiplano de Carangas y el litoral de Arica. A partir de un catastro arqueogeográfico, complementado con datos de excavaciones y dataciones, analizamos el proceso de ordenamiento incaico del valle precordillerano de Belén (ca. 3.000 m snm), el cual era conocido como Tocoroma en los archivos coloniales y constituía la principal isla del archipiélago carangas en la vertiente occidental andina del 18° S. Evidenciamos la producción de un paisaje agrícola imperial en el valle y discutimos la función nodal de Tocoroma-Belén en el contexto de la integración socioterritorial de la transecta Arica-Carangas. Asimismo, el estudio confirma el protagonismo del Tawantinsuyu en la estructuración de los archipiélagos verticales de los Andes Centro-Sur, además de documentar la diversidad de los dispositivos de hegemonía imperial implementados para este fin.

This study examined (1) the association of dietary energy density from solid (EDS) and solid plus liquids (EDSL) with adiposity and cardiometabolic risk factors (CRF) in children with overweight and obesity, (2) the effect of under-reporting on the mentioned associations and (3) whether the association between ED and body composition and CRF is influenced by levels of physical activity. In a cross-sectional design, 208 overweight and obese children (8–12-year-old; 111 boys) completed two non-consecutive 24 h recalls. ED was calculated using two different approaches: EDS and EDSL. Under-reporters were determined with the Goldberg method. Body composition, anthropometry and fasting blood sample measurements were performed. Moderate to vigorous physical activity (MVPA) was registered with accelerometers (7-d-register). Linear regressions were performed to evaluate the association of ED with the previously mentioned variables. Neither EDS nor EDSL were associated with body composition or CRF. However, when under-reporters were excluded, EDS was positively associated with BMI (P=0·019), body fat percentage (P=0·005), abdominal fat (P=0·008) and fat mass index (P=0·018), while EDSL was positively associated with body fat percentage (P=0·008) and fat mass index (P=0·026). When stratifying the group according to physical activity recommendations, the aforementioned associations were only maintained for non-compliers. Cluster analysis showed that the low-ED and high-MVPA group presented the healthiest profile for all adiposity and CRF. These findings could partly explain inconsistencies in literature, as we found that different ED calculations entail distinct results. Physical activity levels and excluding under-reporters greatly influence the associations between ED and adiposity in children with overweight and obesity.

HLA-G expression has been detected in early preimplantation embryos and it has been postulated that a relationship between embryonic expression of this factor and successful pregnancy may exist. Forty-six patients were prospectively selected from our centre ‘Unidad de Reproducción Humana, Hospital Universitario de Canarias’ for conducting this study. In all cases, metaphase II (MII) oocytes were fertilized using intracytoplasmic sperm injection 2–4 h after retrieval. Embryos were cultured individually in 20 µl droplets of G-1 medium (VitroLife) under oil at 37°C and a 6% CO2 environment. Fertilization was assessed at 18 h postinsemination and all oocytes fertilized were passed into a new culture plaque individually in 300 µl culture medium until day 3 of culture. The culture medium was examined for the expression and secretion of sHLA-G with a sandwich enzyme-linked immunosorbent assay kit (BioVendor, Heidelberg, Germany) according to the manufacturer’s instructions. We found statistical significance between higher levels of sHLA-G secretion and pregnancy rate. When both groups were compared there was no difference in embryo quality of transferred embryos, but a significant difference in the number of oocytes and the embryo quality of the cohort existed that was greater in the pregnant group. A standardized sHLA-G assay with a specifically defined range and standard units provides a non-invasive method to identify the most competent embryos for transfer.

Trichomonas vaginalis induces cellular damage to the host cells (cytotoxicity) through the proteolytic activity of multiple proteinases of the cysteine type (CPs). Some CPs are modulated by environmental factors such as iron, zinc, polyamines, etc. Thus, the goal of this study was to assess the effect of glucose on T. vaginalis cytotoxicity, proteolytic activity and the particular role of TvCP2 (TVAG_057000) during cellular damage. Cytotoxicity assays showed that glucose-restriction (GR) promotes the highest HeLa cell monolayers destruction (~95%) by trichomonads compared to those grown under high glucose (~44%) condition. Zymography and Western blot using different primary antibodies showed that GR increased the proteolytic activity, amount and secretion of certain CPs, including TvCP2. We further characterized the effect of glucose on TvCP2. TvCP2 increases in GR, localized in vesicles close to the plasma membrane and on the surface of T. vaginalis. Furthermore, pretreatment of GR-trichomonads with an anti-TvCP2r polyclonal antibody specifically reduced the levels of cytotoxicity and apoptosis induction to HeLa cells in a concentration-dependent manner. In conclusion, our data show that GR, as a nutritional stress condition, promotes trichomonal cytotoxicity to the host cells, increases trichomonad proteolytic activity and amount of CPs, such as TvCP2 involved in cellular damage.

The climate of north-western Spain, with high temperatures and relative humidity during the grapevine vegetative cycle, can especially favour the development of fungal diseases in vineyards. One of the most important diseases is downy mildew, caused by the fungus Plasmopara viticola. The aim of the current study is to propose a system containing phenological data, biological sensors of pathogen indicator and the agrometeorological Goidanich Index in order to optimize the application of downy mildew fungicide treatments. The study was conducted in a vineyard of the ‘Ribeiro’ Designation of Origin region from 2005 to 2016 during the Vitis vegetative period. Aerobiological sampling was performed using a LANZONI VPPS-2000 volumetric trap. The highest number of infection cycles was recorded during the 2009 harvest, with a total of 16 cycles. Years with fewer infection cycles were 2008, 2011 and 2012 (13 cycles). Primary infections were produced during the third fortnight of April and a high amount of secondary infection cycles were detected by the Goidanich algorithm during the fruit development and berry ripening stages. The best estimators of the P. viticola spore concentrations were the fungus spore levels during the previous day, the average temperature 5 days before and rainfall 2 days before. The regression equation obtained accounted for the 95.9% of the spore concentration variation. The combination of the Goidanich index and biological sensors provides a valuable tool to establish an accurate, modern, integrated downy mildew pest-management strategy.

OBJECTIVES/SPECIFIC AIMS: To determine the association of participant’s characteristics and socio-cultural factors including acculturation, community identity and discrimination with the adherence to cancer screening guidelines and participants’ quality of life. METHODS/STUDY POPULATION: As part of the Cancer Disparities Research Network pilot cohort, the study recruited 333 participants across four sites: Boston Chinatown, African American communities in Philadelphia, and Hispanic communities in Columbus, and rural white communities in Appalachia, Ohio. Enrolled participants were eligible if they were 40 to 74 years old, did not live in a nursing home or other facility, and had no prior invasive cancer diagnosis. Additionally, each participant met at least one of the following criteria: living in a medically underserved area, having low literacy, low income (defined as 100% of the 2015 Federal Poverty Level FPL according to 2015 FPL Guidelines), or being uninsured or receiving subsidized health insurance coverage. Participants completed a baseline survey of demographic data, health status, including health behaviors and risk factors to cancer, Primary Care Physician (PCP) status and most recent breast, cervical, prostate, skin and colorectal cancer screenings. Information related to discrimination, acculturation or adaptation, and sense of belonging to their community was collected using validated instruments. RESULTS/ANTICIPATED RESULTS: Of the 333 participants enrolled in the study, 65.5% were women, 14.1% were 40-50 years of age, 59.8% were 51-64 years, and 26.1% were 65-74. The cohort was racially and ethnically diverse: 8.4% of participants identified as Hispanic, 30.3% as non-Hispanic White, 31.2% as non-Hispanic Black, 29.4% as non-Hispanic Asian, and 0.6% as Other. 62.2% spoke English, 8.1% Spanish, and 29.7% Chinese as their primary language. Low incomes were common: 33.6% reported incomes $15,000 or less, and 25.8% reported incomes between $15,000 and $24,999. Overall adherence to USPSTF guidelines on cancer screening rates was 77.9% for breast cancer, 71.1% for cervical cancer, and 67.7% for colorectal cancer. Analyses will present the association of acculturation, community identity, and discrimination with cancer screening and quality of life measures. DISCUSSION/SIGNIFICANCE OF IMPACT: This study will promote the increase of cancer disparities research, and reinforce the importance of inclusion and increased recruitment of diverse populations in future studies. By determining the potential factors associated with cancer disparities among minority populations, it may provide new information for clinicians to have more cultural sensitivity addressing potential disparities in the clinical setting. It will also promote the creation of more tailored interventions and programs to deliver adequate healthcare among these populations.

Our objective was to determine the frequency of zika (ZIKV), chikungunya (CHIKV) and dengue (DENV) virus coinfection and describe the mortality cases that occurred during the epidemiologic surveillance of the ZIKV epidemic in Colombia. We analysed all cases of suspected ZIKV infection that were reported to the National Institute of Health (October 2015–December 2016). DENV, CHIKV and ZIKV RNA were detected in serum or tissue samples using polymerase chain reaction assay. Medical records of the fatal cases were reviewed. We identified that 23 871 samples were processed. The frequency of viral agents was 439 (1.84%) for DENV, 257 (1.07%) for CHIKV and 10118 (42.38%) for ZIKV. Thirty-four (0.14%) cases of coinfection were identified. The CHIKV–ZIKV coinfection was present in 28 cases (82.3%), DENV–CHIKV in three (8.8%) and DENV–ZIKV in three (8.8%). Seven (20.6%) coinfection cases were fatal (two DENV–CHIKV cases and five CHIKV–ZIKV cases). Two cases were foetal deaths and the others were related to neurological syndrome and sepsis. In conclusion, the frequency of arbovirus coinfection during epidemic of ZIKV was low, and CHIKV–ZIKV coinfection was the most common. Mortality was high among coinfection patients. The role of each virus in the mortality cases of coinfection warrants further studies.

This study aimed to evaluate the associations between the muscle mass to visceral fat (MVF) ratio and cardiometabolic risk factors in a large population of college students in Colombia and to propose cut-off points of this index for the metabolic syndrome (MetS). A total of 1464 young adults recruited from the FUPRECOL (Asociación de la Fuerza Prensil con Manifestaciones Tempranas de Riesgo Cardiovascular en Jóvenes y Adultos Colombianos) study were categorised into four groups based on their MVF ratio. Muscle mass and visceral fat level of the participants were measured using a bioelectrical impedance analysis. Cardiometabolic risk factors including lifestyle characteristics, anthropometry, blood pressure and biochemical parameters were assessed. The prevalence of moderate to severe obesity, hypertension and the MetS was higher in subjects in quartile (Q)1 (lower MVF ratio) (P <0·001). ANCOVA revealed that the subjects in Q1 had higher cardiometabolic disturbances, including altered anthropometry, blood pressure, muscle strength and biochemical parameters after adjusting for age and sex compared with young adults in higher MVF ratio quartiles (P <0·001). Muscular mass and physical activity levels were significantly lower in subjects with a lower MVF ratio (P <0·001). The receiver operating characteristic curve analyses indicated that in men the best MVF ratio cut-off point for detecting the MetS was 18·0 (AUC 0·83, sensitivity 78 % and specificity 77 %) and for women, the MVF ratio cut-off point was 13·7 (AUC 0·85, sensitivity 76 % and specificity 87 %). A lower MVF ratio is associated with a higher risk cardiometabolic profile in early adulthood, supporting that the MVF ratio could be used as a complementary screening tool that may help clinicians identify young adults at high cardiometabolic risk.

In approximately 5% of patients with idiopathic recurrent pericarditis, the disease usually follows a chronic relapsing course, and children can develop dependence and side effects of prolonged high-dose corticosteroid regimens. In this setting anakinra, a recombinant human interleukin-1 competitive receptor antagonist that blocks the biologic effects of interleukin-1, thereby reducing systemic inflammatory responses, appears to be one of the most promising strategies. We report an adolescent with steroid-dependent idiopathic recurrent pericarditis that was successfully treated with anakinra, highlighting that this therapeutic option seems to be an effective, rapidly acting, steroid-sparing, and relatively safe agent for the treatment of this entity in children.
