    Several studies have shown that the determination of pH in sweat, which is one of the most accessible body fluids, can be an indicator of health and wellness, and even be used for potential disease diagnosis. On that basis, we present herein a wearable wristband for continuous and wireless monitoring of sweat pH with potential applications in the field of personal health assessment. The developed wristband consists of two main parts: a microfluidic cloth analytical device (μCAD) to collect continuously the sweat from skin with a color-based pH sensing area; and a readout and processing module with a digital color sensor to obtain the pH of sweat from the color changes in the μCAD. In addition, the readout module includes a low-power Bluetooth interface to transmit the measurements in real-time to a custom-designed smartphone application. To allow continuous operation, an absorbent pad was included in the design to retire and store thsweat from the sensing area through a passive pump path. It was found that the Hue parameter (H) in the HSV color space can be related to the sweat pH and fitted to a Boltzmann equation (R2 = 0.997). The range of use of the wristband device goes from 6 to 8, which includes the pH range of sweat, with a precision at different pH values from 3.6 to 6.0 %. Considering the typical human sweat rate, the absorbent pad allows continuous operation up to more than 1000 minutes

    Development Refractoriness of MLL-Rearranged Human B Cell Acute Leukemias to Reprogramming into Pluripotency

    Induced pluripotent stem cells (iPSCs) are a powerful tool for disease modeling. They are routinely generated from healthy donors and patients from multiple cell types at different developmental stages. However, reprogramming leukemias is an extremely inefficient process. Few studies generated iPSCs from primary chronic myeloid leukemias, but iPSC generation from acute myeloid or lymphoid leukemias (ALL) has not been achieved. We attempted to generate iPSCs from different subtypes of B-ALL to address the developmental impact of leukemic fusion genes. OKSM(L)-expressing mono/polycistronic-, retroviral/lentiviral/episomal-, and Sendai virus vector-based reprogramming strategies failed to render iPSCs in vitro and in vivo. Addition of transcriptomic-epigenetic reprogramming ‘‘boosters’’ also failed to generate iPSCs from B cell blasts and B-ALL lines, and when iPSCs emerged they lacked leukemic fusion genes, demonstrating non-leukemic myeloid origin. Conversely, MLL-AF4-overexpressing hematopoietic stem cells/B progenitors were successfully reprogrammed, indicating that B cell origin and leukemic fusion gene were not reprogramming barriers. Global transcriptome/DNA methylome profiling suggested a developmental/differentiation refractoriness of MLL-rearranged B-ALL to reprogramming into pluripotency

    Breast cancer (BC) survivors are advised to follow the WCRF/AICR cancer prevention recommendations, given their high risk of developing a second tumour. We aimed to explore compliance with these recommendations in BC survivors and to identify potentially associated clinical and sociodemographic factors. A total of 420 BC survivors, aged 31-80, was recruited from 16 Spanish hospitals. Epidemiological, dietary and physical activity information was collected through questionnaires. A 7-item score to measure compliance with the recommendations was built according to the 2018 WCRF/AICR scoring criteria. Standardized prevalences and standardized prevalence ratios of moderate and high compliance across participant characteristics were estimated using multinomial and binary logistic regression models. The mean score was 3.9 (SD: 1.0) out of 7 points. Recommendations with the worst adherence were those of limiting consumption of red/processed meats (12% of compliance, 95% CI: 8.2-15.0) and high fibre intake (22% of compliance, 95% CI: 17.6-27.0), while the best compliance was observed for the consumption of fruits and vegetables (73% of compliance, 95% CI: 69.2-77.7). Overall, adherence was worse in women with university education and in those with first-degree relatives with BC. This information may be of interest to design and implement personalized preventive measures adapted to the characteristics of these patients.This research was funded by the Fundación Científica Asociación Española Contra el Cancer (AECC) (Scientific Foundation of the Spanish Association against Cancer 2016).

    Objectives: This study sought to quantify and compare the decline in volumes of cardiovascular procedures between the United States and non-US institutions during the early phase of the coronavirus disease-2019 (COVID-19) pandemic. Background: The COVID-19 pandemic has disrupted the care of many non-COVID-19 illnesses. Reductions in diagnostic cardiovascular testing around the world have led to concerns over the implications of reduced testing for cardiovascular disease (CVD) morbidity and mortality. Methods: Data were submitted to the INCAPS-COVID (International Atomic Energy Agency Non-Invasive Cardiology Protocols Study of COVID-19), a multinational registry comprising 909 institutions in 108 countries (including 155 facilities in 40 U.S. states), assessing the impact of the COVID-19 pandemic on volumes of diagnostic cardiovascular procedures. Data were obtained for April 2020 and compared with volumes of baseline procedures from March 2019. We compared laboratory characteristics, practices, and procedure volumes between U.S. and non-U.S. facilities and between U.S. geographic regions and identified factors associated with volume reduction in the United States. Results: Reductions in the volumes of procedures in the United States were similar to those in non-U.S. facilities (68% vs. 63%, respectively; p = 0.237), although U.S. facilities reported greater reductions in invasive coronary angiography (69% vs. 53%, respectively; p < 0.001). Significantly more U.S. facilities reported increased use of telehealth and patient screening measures than non-U.S. facilities, such as temperature checks, symptom screenings, and COVID-19 testing. Reductions in volumes of procedures differed between U.S. regions, with larger declines observed in the Northeast (76%) and Midwest (74%) than in the South (62%) and West (44%). Prevalence of COVID-19, staff redeployments, outpatient centers, and urban centers were associated with greater reductions in volume in U.S. facilities in a multivariable analysis. Conclusions: We observed marked reductions in U.S. cardiovascular testing in the early phase of the pandemic and significant variability between U.S. regions. The association between reductions of volumes and COVID-19 prevalence in the United States highlighted the need for proactive efforts to maintain access to cardiovascular testing in areas most affected by outbreaks of COVID-19 infection

Spain was one of the European countries with the highest incidence during the first wave. As a part of a consortium to monitor and study the evolution of the epidemic, we sequenced 2,170 samples, diagnosed mostly before lockdown measures. Here, we identified at least 500 introductions from multiple international sources and documented the early rise of two dominant Spanish epidemic clades (SECs), probably amplified by superspreading events. Both SECs were related closely to the initial Asian variants of SARS-CoV-2 and spread widely across Spain. We inferred a substantial reduction in the effective reproductive number of both SECs due to public-health interventions (Re < 1), also reflected in the replacement of SECs by a new variant over the summer of 2020. In summary, we reveal a notable difference in the initial genetic makeup of SARS-CoV-2 in Spain compared with other European countries and show evidence to support the effectiveness of lockdown measures in controlling virus spread, even for the most successful genetic variants.This work was mainly funded by the Instituto de Salud Carlos III project COV20/00140, with additional funding by Spanish National Research Council project CSIC-COV19-021, Ministerio de Ciencia project PID2019-104477RB-100, ERC StG 638553 and ERC CoG 101001038 to I.C., and BFU2017-89594R to F.G.C.

    Influencia del modelo de gestión clínica en la calidad y eficiencia de una unidad asistencial. La relación del modelo con la sostenibilidad de los sistemas públicos de salud

    Get PDF
    Los Sistemas Públicos de Salud (SPS), con financiación pública integra por impuestos, universales y que comprendan la asistencia integral de los pacientes, constituyen un logro social de gran magnitud, por cuanto proveen a los ciudadanos de una protección y prevención de la enfermedad acorde con los derechos y principios básicos recogidos en la Declaración Universal de los Derechos Humanos de 1948. El sostenimiento de los SPS ha comprendido, desde su origen, importantes dificultades para su sostenimiento, agravados en épocas como la actual, donde el gran desarrollo y coste de la ciencia médica, asociado a las profundas crisis económicas que sufren cíclicamente las sociedades que los gestionan, hacen que la viabilidad de tales sistemas, tal y como han sido concebidos, suponga quizá el mayor desafío de gestión de las sociedades occidentales. La calidad y eficiencia, como magnitudes directamente relacionadas, junto con la activa participación de los profesionales en la gestión de los SPS, según los preceptos y filosofía de la Gestión Clínica, constituyen las estrategias más racionales y de mayor eficacia potencial para conseguir el sostenimiento de los mismos, sin que la calidad en la asistencia se vea comprometida. La U.G.C. de CCV ha aplicado estos conceptos desde el año 2008, en que se constituyó, analizándose en el presente documento las estrategias utilizadas y los resultados conseguidos, especialmente en parámetros de calidad, eficiencia y seguridad de pacientes, tras 10 años de actividad continua, sobre 17.852 pacientes y 95.376 estancias en la mencionada unidad clínica de un hospital de tercer nivel.Public Health Systems (PHS), with total public funding for taxes, universal and which comprise the integral assistance of patients, constitute a social achievement of great magnitude, because they provide protection and prevention of the disease to the citizens in line with the rights and principles contained in the Universal Declaration of Human Rights, 1948. The support of PHS has included, from the beginning, significant difficulties for their support, aggravated in times like the present, where the great development and cost of medical science associated with the deep economic crisis that societies that manage them suffer cyclically, make that the feasibility of such systems, as they have been conceived, supposes perhaps the biggest management challenge in the Western Societies. The quality and efficiency together, as magnitudes directly related, with the active participation of professionals in the management of PHS, according to the precepts and the philosophy of Clinical Management, establish more rational and more effective strategies to achieve sustainability of these Services, without the quality of care would be compromised. The U.G.C. CCV has applied these concepts since 2008, when it was established, analyzed in this document the strategies used and the results achieved, especially on parameters of quality, efficiency and safety of patients, after 10 years of continuous activity, 17.852 patients and 95.376 clinic stays in the aforementioned unit of a tertiary hospital

    Tesis (Ingeniero Civil en Minas)El cobre corresponde al principal commodity de la actividad minera nacional, el cual a través de los años ha entregado a la cuenta chilena la posibilidad de beneficiar al país de la mejor manera posible. La demanda de este metal está propensa a aumentar los próximos años debido al crecimiento del mercado de los vehículos eléctricos que consumen unitariamente una mayor cantidad de cobre con respecto a los vehículos de motor de combustión interna. El objetivo central de este trabajo yace en desarrollar un pronóstico óptimo para la demanda de vehículos eléctricos a través de la aplicación de técnicas econométricas y microeconómicas las cuales arrojan resultados para el corto, mediano y largo plazo con una razonable medida de exactitud basados en series temporales iniciales construidas con un rango desde 2017 y 2027. La metodología inicialmente considera el análisis de la estructura de las series de tiempo mediante pruebas de estacionariedad. Posteriormente, con regresiones, suavizamiento exponencial y modelos autorregresivos son mostrados los posibles escenarios. Finalmente, se evalúan los modelos económicos a través de mediciones de exactitud, dígase MAPE, RMSE y residuos entre los pronósticos de vehículos eléctricos, cerrando así el procedimiento de desarrollo de esta tesis. Siendo así una aproximación al modelo de difusión de Bass para el desarrollo de nuevos productos tecnológicos. Un vehículo convencional usualmente consume 23 kg de cobre mientras que las tres variantes estudiadas: HEV, PHEV y BEV (Passenger cars) rondan 40, 60 y 83 kg respectivamente (cifras de ICA). De manera que, según esta tesis, con un MAPE de 3,7% los HEV alcanzarían un máximo de 10 millones de unidades vendidas rondando 2033; los PHEV a MAPE de 6,7% participarán con cantidad demandada de 20 millones de unidades como su valor máximo pronosticado en 2041; por su parte BEV, pueden alcanzar 60 millones al con error MAPE de 2,2% en 2050. Equiparando las ventas de vehículos convencionales cerca del periodo 2036 (MAPE 17%) con 55 millones de unidades. Así, esto significa una proyección total de casi 100 millones de unidades de vehículos eléctricos anualmente demandados, que impactan con un 14% de demanda adicional de cobre con 5 MTon (1,7% MAPE). Asimismo, el modelo desarrollado explica un precio afectado por la variante que ronde los 420 [cUS/Lb]paraellargoplazo.Copperisthemaincommodityinthenationalminingactivity,whichacrosstheyearssendstotheChileanpockettheopportunitytobenefitthebestpossiblewayforthecountry.Thismetaldemandispronetoincreasethenextyearsduetoagrowingupintheelectricvehiclesmarketthatdoesabiggerunitconsumptionthaninternalcombustionengineones(ICEvehicles).TheprincipalgoalonthisworkliesindevelopanoptimalforecastintheEVdemandthroughtheapplicationofeconometricsandmicroeconomicstacticswhichoutputshort,mediumandlongtermresultswithareasonableaccuracybasedontemporalseriesbuiltinarangestartedin2017until2027.Initiallythemethodologyconsidersthetemporalseriesstructureanalysiswithstationaritytests.Then,regressions,exponentialsmoothingandautoregressivemodelsshowdemandpossiblestages.FinallyevaluatetheeconomicsmodelstodefinetheresultsaccuracymeasuredwithMAPE,RMSEandthewasteontheEVforecastclosesthisworkprocess.Beingthisway,anapproximationtotheBassdiffusionmodelfornewtechnologyproduct.AnICEcarusuallyconsumes23kgandthethreealternativesstudied:HEV,PHEVandBEV(passengercars)nearly40,60and83kgrespectively(ICAstudies).Accordingthisthesisandwitha3,7So,thismeans,atotaldemandforecastthatoutputsalmost100millionunitsofEVthatimpactsa14/Lb] para el largo plazo.Copper is the main commodity in the national mining activity, which across the years sends to the Chilean pocket the opportunity to benefit the best possible way for the country. This metal demand is prone to increase the next years due to a growing up in the electric vehicles market that does a bigger unit consumption than internal combustion engine ones (ICE vehicles). The principal goal on this work lies in develop an optimal forecast in the EV demand through the application of econometrics and microeconomics tactics which output short, medium- and long-term results with a reasonable accuracy based on temporal series built in a range started in 2017 until 2027. Initially the methodology considers the temporal series structure analysis with stationarity tests. Then, regressions, exponential smoothing and autoregressive models show demand possible stages. Finally evaluate the economics models to define the results accuracy measured with MAPE, RMSE and the waste on the EV forecast closes this work process. Being this way, an approximation to the Bass diffusion model for new technology product. An ICE car usually consumes 23 kg and the three alternatives studied: HEV, PHEV and BEV (passenger cars) nearly 40, 60 and 83 kg respectively (ICA studies). According this thesis and with a 3,7% MAPE, the HEV will be around 10 million units sales as maximum to 2033; PHEV corresponds a 6,7% MAPE and 20 million as the biggest value in the forecasts developed near 2041; BEV, in turn can reach 60 million unit in 2050 with 2,2% MAPE. Matching the ICE vehicles sales around 2036 (MAPE 17%) with 55 million unit. So, this means, a total demand forecast that outputs almost 100 million units of EV that impacts a 14% in the copper long term demand with additionally 5 Mton (1,7% MAPE). Also, the developed model explains an impacted price by EV that approaches 420 [cUS/Lb]
