El propósito de esta investigación es desarrollar una nueva metodología de dirección de proyectos de construcción en Panamá, en donde los procesos de los métodos tradicionales sean fortalecidos con técnicas ágiles para lograr proyectos de construcción más dinámicos, eficientes, orientados a resultados y exitosos. Las empresas constructoras en Panamá no cuentan con profesionales, procesos ni la cultura organizacional necesaria para lograr los resultados esperados, existe una deficiente dirección; esto origina proyectos no culminados dentro del plazo, costo ni con la calidad esperada, otros no se terminan, gastos inasumibles, mala imagen empresarial, penalizaciones, pérdida de clientes, conflictos internos y externos. El origen del problema es que en Panamá no existe una metodología aplicable por los profesionales como guía general para proyectos de construcción. Esta investigación será descriptiva, utilizando el método inductivo, se partirá de normativas internacionales de metodologías tradicionales y ágiles actualmente aplicadas separadamente en el campo de dirección de proyectos. Mediante la presente investigación, se desarrollará una metodología híbrida en la que lo tradicional y lo ágil se complementan, con dicha integración se espera lograr gestiones robustas que incrementen la posibilidad de éxito en los proyectos de construcciones panameñas. El enfoque será mixto integrando datos cuantitativos y cualitativos. En esta investigación, se utilizará como base la Norma Internacional “Directrices para la Dirección y Gestión de Proyectos, ISO 21500”, que proporciona una descripción de alto nivel sobre conceptos y procesos de dirección de proyectos; los que se integrarán con conceptos y técnicas de metodologías ágiles. Al culminar esta investigación se espera validar una metodología híbrida de dirección para proyectos de construcción más dinámica y flexible, que permita a los directores planificar, ejecutar y dirigir más adecuadamente los proyectos de construcción en Panamá; logrando proyectos más exitosos, mayores beneficios económicos para las empresas constructoras, clientes más satisfechos y profesionales más capacitados.

Resumen
El propósito de esta investigación es desarrollar una nueva metodología de dirección de proyectos de construcción en Panamá, en donde los procesos de los métodos tradicionales sean fortalecidos con técnicas ágiles para lograr proyectos de construcción más dinámicos, eficientes, orientados a resultados y exitosos. Las empresas constructoras en Panamá no cuentan con profesionales, procesos ni la cultura organizacional necesaria para lograr los resultados esperados, existe una deficiente dirección; esto origina proyectos no culminados dentro del plazo, costo ni con la calidad esperada, otros no se terminan, gastos inasumibles, mala imagen empresarial, penalizaciones, pérdida de clientes, conflictos internos y externos. El origen del problema es que en Panamá no existe una metodología aplicable por los profesionales como guía general para proyectos de construcción. Esta investigación será descriptiva, utilizando el método inductivo, se partirá de normativas internacionales de metodologías tradicionales y ágiles actualmente aplicadas separadamente en el campo de dirección de proyectos. Mediante la presente investigación, se desarrollará una metodología híbrida en la que lo tradicional y lo ágil se complementan, con dicha integración se espera lograr gestiones robustas que incrementen la posibilidad de éxito en los proyectos de construcciones panameñas. El enfoque será mixto integrando datos cuantitativos y cualitativos. En esta investigación, se utilizará como base la Norma Internacional “Directrices para la Dirección y Gestión de Proyectos, ISO 21500”, que proporciona una descripción de alto nivel sobre conceptos y procesos de dirección de proyectos; los que se integrarán con conceptos y técnicas de metodologías ágiles. Al culminar esta investigación se espera validar una metodología híbrida de dirección para proyectos de construcción más dinámica y flexible, que permita a los directores planificar, ejecutar y dirigir más adecuadamente los proyectos de construcción en Panamá; logrando proyectos más exitosos, mayores beneficios económicos para las empresas constructoras, clientes más satisfechos y profesionales más capacitados.

The main aim of this study was to analyse the influence of e-learning training on the acquisition of competences in basketball coaches in Cantabria. The current landscape of basketball coach training shows an increasing demand for innovative training models and emerging pedagogies, including e-learning-based methodologies. The study sample consisted of fifty students from these courses, all above 16 years of age (36 males, 14 females). Among them, 16% resided outside the autonomous community of Cantabria, 10% resided more than 50 km from the city of Santander, 36% between 10 and 50 km, 14% less than 10 km, and 24% resided within Santander city. Data were collected through a Google Forms survey distributed by the Cantabrian Basketball Federation to training course students. Participation was voluntary and anonymous. The survey, consisting of 56 questions, was validated by two sports and health doctors and two senior basketball coaches. The collected data were processed and analysed using Microsoft® Excel version 16.74, and the results were expressed in percentages. The analysis revealed that 24.60% of the students trained through the e-learning methodology considered themselves fully qualified as basketball coaches, contrasting with 10.98% of those trained via traditional face-to-face methodology. The results of the study provide insights into important characteristics that can be adjusted and improved within the investigated educational process. Moreover, the study concludes that e-learning training effectively qualifies basketball coaches in Cantabria.

Carotenoids Intake and Cardiovascular Prevention: A Systematic Review
Background: Cardiovascular diseases (CVDs) encompass a variety of conditions that affect the heart and blood vessels. Carotenoids, a group of fat-soluble organic pigments synthesized by plants, fungi, algae, and some bacteria, may have a beneficial effect in reducing cardiovascular disease (CVD) risk. This study aims to examine and synthesize current research on the relationship between carotenoids and CVDs. Methods: A systematic review was conducted using MEDLINE and the Cochrane Library to identify relevant studies on the efficacy of carotenoid supplementation for CVD prevention. Interventional analytical studies (randomized and non-randomized clinical trials) published in English from January 2011 to February 2024 were included. Results: A total of 38 studies were included in the qualitative analysis. Of these, 17 epidemiological studies assessed the relationship between carotenoids and CVDs, 9 examined the effect of carotenoid supplementation, and 12 evaluated dietary interventions. Conclusions: Elevated serum carotenoid levels are associated with reduced CVD risk factors and inflammatory markers. Increasing the consumption of carotenoid-rich foods appears to be more effective than supplementation, though the specific effects of individual carotenoids on CVD risk remain uncertain.

The evolution of the COVID-19 pandemic has been associated with variations in clinical presentation and severity. Similarly, prediction scores may suffer changes in their diagnostic accuracy. The aim of this study was to test the 30-day mortality predictive validity of the 4C and SEIMC scores during the sixth wave of the pandemic and to compare them with those of validation studies. This was a longitudinal retrospective observational study. COVID-19 patients who were admitted to the Emergency Department of a Spanish hospital from December 15, 2021, to January 31, 2022, were selected. A side-by-side comparison with the pivotal validation studies was subsequently performed. The main measures were 30-day mortality and the 4C and SEIMC scores. A total of 27,614 patients were considered in the study, including 22,361 from the 4C, 4,627 from the SEIMC and 626 from our hospital. The 30-day mortality rate was significantly lower than that reported in the validation studies. The AUCs were 0.931 (95% CI: 0.90–0.95) for 4C and 0.903 (95% CI: 086–0.93) for SEIMC, which were significantly greater than those obtained in the first wave. Despite the changes that have occurred during the coronavirus disease 2019 (COVID-19) pandemic, with a reduction in lethality, scorecard systems are currently still useful tools for detecting patients with poor disease risk, with better prognostic capacity.

Diabetes is a persistent health condition led by insufficient use or inappropriate use of insulin in the body. If left undetected, it can lead to further complications involving organ damage such as heart, lungs, and eyes. Timely detection of diabetes helps obtain the right medication, diet, and exercise plan to lead a healthy life. ML approach has been utilized to obtain rapid and reliable diabetes detection, however, existing approaches suffer from the use of limited datasets, lack of generalizability, and lower accuracy. This study proposes a novel feature extraction approach to overcome these limitations by using an ensemble of convolutional neural network (CNN) and long short-term memory (LSTM) models. Multiple datasets are combined to make a larger dataset for experiments and multiple features are utilized for investigating the efficacy of the proposed approach. Features from the extra tree classifier, CNN, and LSTM are also considered for comparison. Experimental results reveal the superb performance of CNN-LSTM-based features with random forest model obtaining a 0.99 accuracy score. This performance is further validated by comparison with existing approaches and k-fold cross-validation which shows the proposed approach provides robust results.

Assessment of side effects associated with COVID-19 vaccination is required to monitor safety issues and acceptance of vaccines in the long term. We found a significant knowledge gap in the safety profile of COVID-19 vaccines in Bangladesh. We enrolled 1805 vaccine recipients from May 5, 2021, to April 4, 2023. Kruskal-Wallis test and χ2 test were performed. Multivariable logistic regression was also performed. First, second and third doses were administered among 1805, 1341, and 923 participants, respectively. Oxford–AstraZeneca (2946 doses) was the highest administered followed by Sinopharm BIBP (551 doses), Sinovac (214 doses), Pfizer-BioNTech (198 doses), and Moderna (160 doses), respectively. Pain at the injection site (80-90%, 3200–3600), swelling (85%, 3458), redness (78%, 3168), and heaviness in hand (65%, 2645) were the most common local effects, and fever (85%, 3458), headache (82%, 3336), myalgia (70%, 2848), chills (67%, 2726), muscle pain (60%, 2441) were the most prevalent systemic side effects reported within 48 h of vaccination. Thrombosis was only reported among the Oxford–AstraZeneca recipients (3.5-5.7%). Both local and systemic effects were significantly associated with the Oxford–AstraZeneca (p-value < 0.05), Pfizer–BioNTech (p-value < 0.05), and Moderna (p-value < 0.05) vaccination. Chronic urticaria and psoriasis were reported by 55-60% of the recipients after six months or later. The highest percentage of local and systemic effects after 2nd and 3rd dose were found among recipients of Moderna followed by Pfizer-BioNTech and Oxford–AstraZeneca. Homogenous doses of Oxford–AstraZeneca and heterogenous doses of Moderna and Pfizer-BioNTech were significantly associated with elevated adverse effects. Females, aged above 60 years with preexisting health conditions had higher risks. Vaccination with Pfizer-BioNTech (OR 4.34, 95% CI 3.95–4.58) had the highest odds of severe and long-term effects followed by Moderna (OR 4.15, 95% CI 3.92–4.69) and Oxford–AstraZeneca (OR 3.89, 95% CI 3.45–4.06), respectively. This study will provide an integrated insight into the safety profile of COVID-19 vaccines.
