Hydrography and dynamics of Port Foster, Deception Island, Antarctica

The circulation and water masses of Port Foster, Deception Island, were studied using conductivity-temperature-depth stations inside and outside the semi-enclosed bay and an array of bottom temperature sensors moored around the perimeter of the bay over two weeks in the summer of 2012. Inside Port Foster, the water column is divided into two layers separated by a temperature-forced, seasonal pycnocline at ~40–60 m. The circulation of the upper layer is in an anticlockwise direction, with mean geostrophic currents of ~0.04–0.10 ms^(-1). The lower layer, from ~60 m to the seabed, shows coastal-trapped waves travelling in a clockwise direction, possibly triggered by local wind gusts. Local sea ice melt in areas surrounding the underwater hot springs of Pendulum Cove appears as a fresh, warm anomaly down to 30 m

Implementación de data lake en la nube para análisis de movilidad en la Ciudad de México y la ZMG

Se presenta una breve introducción al proyecto data lake en la nube para análisis de movilidad en la Ciudad de México y la Zona Metropolitana de Guadalajara. El cual tiene como objetivo principal generar una infraestructura que es creada con servicios de computación en la nube ofrecidos por Amazon Web Services con el fin de cargar, integrar, procesar y analizar datos de movilidad urbana registrados por los organismos que ofrecen dichos servicios, para de esta manera poder detectar y generar métricas y análisis que a su vez puedan dar soluciones y/o propuestas a los actuales problemas de movilidad que ambas ciudades presentan. Es posible observar que la implementación del data lake trae consigo una gran mejora a los procesos comúnmente utilizados para llevar a cabo este tipo de análisis, pues se utilizan los datos de diferentes servicios de movilidad sin importar su estructura y tipo de almacenamiento, a fin de tener una integración total, generando un catálogo de metadatos el cual tiene como tarea principal el mapear los procesos de análisis con los datos almacenados físicamente en S3. Finalmente, tras completar la fase de procesamiento de la información, se llevan a cabo diferentes tipos de análisis haciendo uso de tecnologías comunes, como lo son las consultas SQL, generación de dashboards y predicciones con ML, los cuales permiten confirmar y validar la importancia de tener una tecnología centralizada de análisis que sea capaz de producir resultados válidos sin tener que lidiar directamente con las diferencias estructurales inherentes de los datos utilizados.ITESO, A.

La lectura no utilitaria en la universidad en la era digital. Un análisis multivariante que ubica el texto impreso en la lectura de literatura

This paper explores the preference of the printed text for reading literature in a university community. A characterization of reading and writing in the university is made and a review of the importance of non-utilitarian reading is presented in this context. The issue of the appropriation of ICT in the university environment is reviewed, identifying the relevance of reading and writing in the digital age. The case study uses data from a survey applied at the Universidad Veracruzana, for which the context and background are presented. A description of the variables and the strategy of statistical analysis is made. We analyze the factors that are associated with the format preference and characterize the main associations based on independence tests using the Chi-Square statistic; for multivariate associations, a multiple correspondence analysis was run. It is concluded that the preference of the printed text is still very marked, a little more among women, highlighting the level of taste and time of dedication among academics and officials. However, the concept of reading that is more frequent is related to the utilitarian reading

Contact dermatitis due to personal protective equipment use and hygiene practices during the COVID-19 pandemic: A systematic review of case reports

Background: Prolonged use of personal protective equipment (PPE) may lead to contact dermatitis during the coronavirus disease 19 (COVID-19) pandemic. This paper aims to identify the causative factors of contact dermatitis from PPE and hygiene practices.Methods: The search was conducted adhering to PRISMA 2020 guidelines. A Delphi process was employed to ensure that the aims of this study were met. PubMed and Web of Science databases were systematically searched through September 12, 2021, using search terms: Contact dermatitis, case report, covid-19. The findings were tabulated as author/year, gender, age, presentation, cause, dermatological diagnosis, testing modality, provided treatment, symptom resolution (time in days), prognosis, and follow-up.Results: The mean age of all individuals was 29.75 years, with 75% females. All cases presented with erythema, with 62.5% reporting pruritus and 37.5% reporting burning facial symptoms. Surgical masks and hand-hygiene products (37.5%) were the most commonly reported causative agent with 25% due to KN95/FFP type 2 use. Allergic contact dermatitis (50%) and irritant contact dermatitis (25%) were common diagnoses. Treatments included creams, emollients, and desloratadine, with restriction of irritant-causing factors. The prognosis was generally good among the cases, with 62.5% presenting complete resolution within a week and 12.5% showing moderate improvement at the fourth month after discontinuing use.Conclusion: This study finds pertinent links between PPE use and contact dermatitis during the COVID-19 pandemic. While many cases are bound to go underreported in literature, well-designed, large-scale studies in the future may help promote these associations in a more comprehensive manner

Prescription refill, patient self-report and physician report in assessing adherence to oral endocrine therapy in early breast cancer patients: a restrospective cohort study in Catalonia, Spain.

AIMS: To compare different methods in order to assess adherence and persistence with oral endocrine therapy in women diagnosed with breast cancer (BC) in Catalonia. MATERIALS AND METHODS: This study covered all women newly diagnosed with stage I, II or IIIa BC and positive hormone receptors at six hospitals in Catalonia (Spain) in 2004. Adherence was assessed on the basis of physician report and patient self-report using a telephone questionnaire. Persistence was measured by refill prescriptions. We used the Kappa index to compare adherence measures and logistic regression to evaluate adherence-related risk factors. RESULTS: The study covered a total of 692 women. Adherence ranged from 92% (self-report) to 94.7% (physician report), depending on the measure used; persistence was 74.7% at 5 years of follow-up. Low concordance between measures was observed (Kappa range: 0.018-0.267). Patients aged 50-74 years showed higher adherence than those aged <50 years. Adherence was also associated with: adjuvant chemotherapy and sequential hormonal therapy. CONCLUSIONS: Concordance between the different measures was remarkably low, indicating the need for further research. Adherence is an issue in the management of BC patients taking oral drugs, and should be assessed in clinical practice

A contemporary picture of enterococcal endocarditis

BACKGROUND: Enterococcal endocarditis (EE) is a growing entity in Western countries. However, quality data from large studies is lacking. OBJECTIVES: The purpose of this study was to describe the characteristics and analyze the prognostic factors of EE in the GAMES cohort. METHODS: This was a post hoc analysis of a prospectively collected cohort of patients from 35 Spanish centers from 2008 to 2016. Characteristics and outcomes of 516 cases of EE were compared with those of 3,308 cases of nonenterococcal endocarditis (NEE). Logistic regression and Cox proportional hazards regression analysis were performed to investigate risk factors for in-hospital and 1-year mortality, as well as relapses. RESULTS: Patients with EE were significantly older; more frequently presented chronic lung disease, chronic heart failure, prior endocarditis, and degenerative valve disease; and had higher median age-adjusted Charlson score. EE more frequently involved the aortic valve and prosthesis (64.3% vs. 46.7%; p < 0.001; and 35.9% vs. 28.9%; p = 0.002, respectively) but less frequently pacemakers/defibrillators (1.5% vs. 10.5%; p < 0.001), and showed higher rates of acute heart failure (45% vs. 38.3%; p = 0.005). Cardiac surgery was less frequently performed in EE (40.7% vs. 45.9%; p = 0.024). No differences in in-hospital and 1-year mortality were found, whereas relapses were significantly higher in EE (3.5% vs. 1.7%; p = 0.035). Increasing Charlson score, LogEuroSCORE, acute heart failure, septic shock, and paravalvular complications were risk factors for mortality, whereas prior endocarditis was protective and persistent bacteremia constituted the sole risk factor for relapse. CONCLUSIONS: Besides other baseline and clinical differences, EE more frequently affects prosthetic valves and less frequently pacemakers/defibrillators. EE presents higher rates of relapse than NEE.
