Proyecto Ronda Cocktails

El presente proyecto lleva el nombre de “Ronda Cocktails”, esta es una empresa que ofrece la opción de poder preparar sus propios cócteles, teniendo todos los insumos necesarios para realizarlo. Con el objetivo de facilitar y reducir el tiempo que se usa para la compra de ingredientes y finalmente compartir experiencias para su mayor satisfacción y aprendizaje. Para su desarrollo, se identificó un interés de preparar cócteles, sin embargo, no suelen encontrar todos los ingredientes en un mismo lugar y por ello sienten que es mejor preparar las bebidas tradicionales. Asimismo, los consumidores no están informados sobre la cantidad necesaria a usar para la preparación, existe mucha información que genera dudas e inseguridades sobre el cóctel y de su procedencia de la receta. Por ello, Ronda Cocktails está dirigido a hombres y mujeres de Lima Metropolitana y Callao, de un rango de edad de 18 a 45 que son amantes de los cócteles. Nuestra principal comunicación con los clientes será por medio de Facebook e Instagram, ya que facilita la interacción, mostrándoles los productos de nuestra carta, experiencia de otros clientes, promociones y atributos de nuestro box de Ronda para un mayor interés, seguridad y confianza. Para poder llevar a cabo el presente trabajo de investigación, se han analizado factores del entorno, análisis del cliente, campañas publicitarias, aprendizajes y estrategias para desarrollar exitosamente nuestro proyecto. Para finalizar, se han realizado los pronósticos y plan financiero, mostrando el resultado del sustento sobre la viabilidad del negocio de Ronda Cocktails.This project is called "Ronda Cocktails", this is a company that offers the option to prepare their own cocktails, having all the necessary inputs to do so. With the objective of facilitating and reducing the time used for the purchase of ingredients and finally sharing experiences for greater satisfaction and learning. For its development, an interest in preparing cocktails was identified, however, they do not usually find all the ingredients in one place and therefore feel it is better to prepare traditional drinks. Also, consumers are not informed about the necessary amount to use for the preparation, there is a lot of information that generates doubts and insecurities about the cocktail and its origin of the recipe. For this reason, Ronda Cocktails is aimed at men and women in Metropolitan Lima and Callao, between 18 and 45 years of age, who are cocktail lovers. Our main communication with customers will be through Facebook and Instagram, as it facilitates interaction, showing them the products of our menu, experience of other customers, promotions and attributes of our Ronda box for greater interest, security and confidence. In order to carry out this research work, we have analyzed environmental factors, customer analysis, advertising campaigns, learning and strategies to successfully develop our project. Finally, we have made forecasts and financial plans, showing the result of the support on the viability of the business of Ronda Cocktails.Trabajo de investigació

Small renal masses in Latin-American population : Characteristics and prognostic factors for survival, recurrence and metastasis - A multi-institutional study from LARCG database

To evaluate demographic, clinical and pathological characteristics of small renal masses (SRM) (≤ 4 cm) in a Latin-American population provided by LARCG (Latin-American Renal Cancer Group) and analyze predictors of survival, recurrence and metastasis. A multi-institutional retrospective cohort study of 1523 patients submitted to surgical treatment for non-metastatic SRM from 1979 to 2016. Comparisons between radical (RN) or partial nephrectomy (PN) and young or elderly patients were performed. Kaplan-Meier curves and log-rank tests estimated 10-year overall survival. Predictors of local recurrence or metastasis were analyzed by a multivariable logistic regression model. PN and RN were performed in 897 (66%) and 461 (34%) patients. A proportional increase of PN cases from 48.5% (1979-2009) to 75% (after 2009) was evidenced. Stratifying by age, elderly patients (≥ 65 years) had better 10-year OS rates when submitted to PN (83.5%), than RN (54.5%), p = 0.044. This disparity was not evidenced in younger patients. On multivariable model, bilaterality, extracapsular extension and ASA (American Society of Anesthesiologists) classification ≥3 were predictors of local recurrence. We did not identify significant predictors for distant metastasis in our series. PN is performed in Latin-America in a similar proportion to developed areas and it has been increasing in the last years. Even in elderly individuals, if good functional status, sufficiently fit to surgery, and favorable tumor characteristics, they should be encouraged to perform PN. Intending to an earlier diagnosis of recurrence or distant metastasis, SRM cases with unfavorable characteristics should have a more rigorous follow-up routine

Mood State Detection in Handwritten Tasks Using PCA–mFCBF and Automated Machine Learning

In this research, we analyse data obtained from sensors when a user handwrites or draws on a tablet to detect whether the user is in a specific mood state. First, we calculated the features based on the temporal, kinematic, statistical, spectral and cepstral domains for the tablet pressure, the horizontal and vertical pen displacements and the azimuth of the pen’s position. Next, we selected features using a principal component analysis (PCA) pipeline, followed by modified fast correlation–based filtering (mFCBF). PCA was used to calculate the orthogonal transformation of the features, and mFCBF was used to select the best PCA features. The EMOTHAW database was used for depression, anxiety and stress scale (DASS) assessment. The process involved the augmentation of the training data by first augmenting the mood states such that all the data were the same size. Then, 80% of the training data was randomly selected, and a small random Gaussian noise was added to the extracted features. Automated machine learning was employed to train and test more than ten plain and ensembled classifiers. For all three moods, we obtained 100% accuracy results when detecting two possible grades of mood severities using this architecture. The results obtained were superior to the results obtained by using state-of-the-art methods, which enabled us to define the three mood states and provide precise information to the clinical psychologist. The accuracy results obtained when detecting these three possible mood states using this architecture were 82.5%, 72.8% and 74.56% for depression, anxiety and stress, respectively

Seroprevalence of Anti-SARS-CoV-2 Antibodies in Blood Donors from Nuevo Leon State, Mexico, during 2020: A Retrospective Cross-Sectional Evaluation

The progression and distribution of the SARS-CoV-2 pandemic are continuously changing over time and can be traced by blood donors’ serological survey. Here, we investigated the seroprevalence of anti-SARS-CoV-2 antibodies in blood donors in Nuevo Leon, Mexico during 2020 as a strategy for the rapid evaluation of the spread of SARS-CoV-2 and asymptomatic case detection. We collected residual plasma samples from blood donors who attended two regional donation centers from January to December of 2020 to identify changes in anti-SARS-CoV-2 IgG prevalence. Plasma samples were analyzed on the Abbott Architect instrument using the commercial Abbott SARS-CoV-2 IgG chemiluminescent assay. We found a total of 99 reactive samples from 2068 analyzed plasma samples, resulting in a raw prevalence of 4.87%. Donors aged 18–49 years were more likely to be seropositive compared to those aged >50 years (p < 0.001). Weekly seroprevalence increased from 1.8% during the early pandemic stage to 27.59% by the end of the year. Prevalence was 1.46-fold higher in females compared to males. Case geographical mapping showed that Monterrey city recorded the majority of SARS-CoV-2 cases. These results show that there is a growing trend of seroprevalence over time associated with asymptomatic infection that is unnoticed under the current epidemiological surveillance protocols
