ABSTRACT
In Higher Education, hybrid sessions have been implemented in higher education that may remain in place beyond the times of teaching emergency caused by the COVID-19 pandemic. This mixed modality presents several uncertainties among teachers and students. Especially in the first case, questions arise about how to design the lesson sequencing, which platforms to use, among many others. This research aims to study the perceptions of teachers and students about interactive synchronous videoconferences, carried out by 5 coordinating teachers of 3 different subjects of the Faculty of Education of the University of Barcelona. The tools used are Bb Collaborate to manage the videoconference and Nearpod to present the learning content and the interactive activities that favor the interaction among students and with the contents. A qualitative analysis of the teachers' perception of the design and development of the sessions has been carried out through self-reporting and a sample of 82 students from the learning analytics and an online form with open questions. The results indicate that this methodology is adequate with the students' way of learning, increasing their participation. The results indicate that the teachers do not appreciate significant differences with respect to the preparation of the sequencing lesson plan of expository classes, although the level of teachers' digital competence is a key factor. Students and teachers value positively the information in the learning analytics of the platform. These positive results may encourage teachers to use this type of pedagogical approaches and tools based on interactivity.
ABSTRACT
Background: Obesity is a chronic and relapsing disease, with a rising prevalence and a high economic burden. Obesity is a risk factor for COVID-19 infection severity and mortality. Anti-obesity medications (AOMs) are safe and effective for weight loss. However, weight loss outcomes with AOMs during the COVID-19 pandemic are yet to be described. We hypothesized that weight loss outcomes with AOMs during COVID-19 are inferior to those before this period. Methods: We performed a systematic review of electronic medical record of patients from the Mayo Clinic Health System. We included all patients who started a long-term FDA-approved AOM (phentermine-topiramate extended release [PHEN-TOP], naltrexone-bupropion sustained release [NBSR], and liraglutide 3.0 mg). We excluded patients with a history of bariatric surgery or endoscopic procedure, those taking ≥2 AOMs, ≥3 months of prescribed AOM, and/or pregnancy. Demographic and anthropometric data were ed from in person or virtual encounters. Analysis was divided by 1) those who started an AOM at least a year before COVID-19 restrictions were set in place in the USA (i.e. first quarter of 2019 period or earlier, defined as “PreCOVID-19”), and 2) those who started an AOM during or after the first quarter of 2020, (defined as “COVID-19''). We calculated the total body weight loss percentage (TBWL%) at 3, 6, and 12 months after AOM initiation along with the percentage of patients who achieved a TBWL ³5% and ³10%, after one year of starting an AOM. Our primary endpoint was the TBWL% at 12 months. All tests were two-tailed and p-value <0.05 was considered statistically significant. Values are presented as mean ± standard deviation (SD). Results: A total of 249 patients were included in the analysis (77% female, age 48.8±12.6 years, body-mass index [BMI] 41.9±8.6 kg/m2). There were no differences in baseline characteristics between both groups (Table 1). Fifty-five percent of the patients were prescribed PHEN-TOP, 16% NBSR, and 29% liraglutide. There was a statistical difference in TBWL% between the PreCOVID-19 group compared to the COVID-19 group: 5.3±3.5% vs 4±3.7% (p=0.03) and 9.6±7% vs 6.5±5.3% (p=0.02) at 3 and 12 months, respectively (Fig. 1A). After 1 year follow-up, 53.6% of patients in the COVID-19 group achieved >5% TBWL compared with 75.3% in the PreCOVID-19 group (p=0.04), and 17.9% of patients in the COVID-19 group achieved 105% TBWL compared with 44.7% in the PreCOVID-19 group (p=0.01) (Fig. 1B). Conclusion: This study shows that weight loss outcomes to AOMs were inferior when prescribed during COVID-19 pandemic, compared to the outcomes observed prior to this. Further studies are needed to understand whether this observation is due to changes in care delivery during the pandemic or due to individual factors such as stress, decreased physical activity, remote working, among others.(Table Presented)Table 1.

ABSTRACT
Due to the Covid 2020 pandemic, the world has faced several economic and lifestyle changes, which have been reflected in new ways of interacting and acting to avoid the spread of the virus. But these changes have not only brought negative things, due to the nature of social distancing and high contagion, governments and companies have been forced to consider technological and regulatory alternatives that can help reduce or eliminate the risks of contagion, modernizing and improving several technologically deficient sectors to current needs. For this reason, the innovative research was carried out from 2021 under the supervision of the School of Mechatronics Engineering at Ricardo Palma University, it was designed a mobile robot that can disinfect public transport using UV-C rays. This study presents mechatronics conceptual design and kinematic analysis, where SolidWorks 2020 is used to design the 3D structure. In addition, this device can climb small ladders with Tri-star wheels, composed of three 130 mm onmiwheels, as well as mecanum wheels that provide maneuverability to improve its range of displacement. The robot has IR sensors for the detection of obstacles and thermal sensors for the detection of people in the work area. It is programmed on a Raspberry Pi 4. The robot is pretended to be applied on regular public transportation and terminals to automatically disinfect them as long as there are no people around. In conclusion, favorable results were achieved;consequently, the next step of this project is to start developing a prototype applying the SLAM technique to generate 3D maps of the interior of public transport. © 2022 IEEE.
ABSTRACT
The objective of the research was to analyse the development of mathematical competences and soft skills in graduate students through the implementation of the Project-Based Learning methodology in times of COVID-19. The type of study used was a quantitative methodology with a descriptive scope. The instrument used to obtain the information was a questionnaire based on a five-point Likert scale. The main results were that the participants developed the mathematical competences of using mathematical terminology, formulating and estimating the quantitative model. The soft skills developed were time management, collaborative work, self-regulation and decision-making.
ABSTRACT
The recent SARS-CoV-2 pandemic has significantly impacted the general population. In COVID-19 infection, a high mortality rate has been observed in patients with comorbid disease, especially in chronic kidney injury. This is a pathology of rapid and progressive evolution since it is accompanied by metabolic acidosis, requiring immediate hemodialysis therapy. This procedure removes toxic waste due to a lack of kidney function. The objective of this work is to determine the impact of COVID-19 on the management of patients on hemodialysis therapy at the IESS Ambato Hospital. It was identified that the most frequent manifestations of this pathology are proteinuria and the nephrotic range. In addition, it presents comorbidities such as arterial hypertension, anemia, and diabetes mellitus, which are risk factors, along with advanced age and immunosuppression. The most frequent symptoms identified were: diarrhea and abdominal pain, caused by hypotension. For the hemodialysis procedure, the supine position is essential as it decreases the ultrafiltration rate. Patients who receive this maintenance therapy are more susceptible since their immune system is compromised by complications secondary to the infection or the procedure.
ABSTRACT
Introduction: Type 2 Diabetes Mellitus is a chronic disease that predominates in adults, but its incidence has been increasing in children and adolescents in recent years according to WHO figures. Currently there are few studies on the prevalence of DM2 in children and adolescents, however, the annual incidence of DM2 between 2011 and 2012 was 5,300 cases among the population aged 10 to 19 years according to the National Statistics Report Diabetes Report of the United States of 2017. Currently in Colombia there is no specific data on DM2 in this population group. Objective: Characterize the prevalence of DM2 in the population aged 10 to 19 years of the city of Bogotá in the period between 2015-2019 and the risk factors Methods: A descriptive, cross-sectional study was carried out without population intervention, using national statistical sources (DANE and SISPRO) and digital tools for the calculation and graphic analysis of the collected information. Results: In Bogotá, Colombia, the highest prevalence of DM2 is in the age range of 15 to 19 years in females regardless of the year during the period 2015-2019. Conclusions: The incidence of childhood and juvenile DM2 tends to increase despite fluctuations over time. In Accordance with the literature, it is affirmed that the increase in obesity, metabolic syndrome, new lifestyles and family inheritance are the most relevant risk factors for developing DM2, which represents a challenge for public health in terms of its prevention and monitoring worldwide.
ABSTRACT
The first challenge we face in this 21st century is to be able to feed all the inhabitants of this planet with safe and healthy food in a sustainable way. There are societies where the main problem is the availability of food, which leads to malnutrition and diseases of poverty (mainly communicable). In other societies, the availability of food is not the problem, but paradoxically there are cases of malnutrition due to poor dietary choices, which lead to the so-called wealth diseases (non-communicable), such as cardiovascular diseases as the main cause of mortality. The emergence at the beginning of 2020 of the emergency caused by the SARS-Cov2 coronavirus has made this situation a new challenge throughout the world, without distinction of countries with high or low income. The speech aims to address the importance of maintaining an adequate nutritional status to maintain good health, minimize the negative effects caused by COVID-19 as well as facilitate the recovery of patients. Scientific evidence regarding the role of micronutrients and bioactive compounds in strengthening the immune system will be reviewed, a synergistic beneficial effect based on their complementary mechanisms of action. It will also discuss the new concept of "planetary health diet" that considers the relevance of dietary choices, due to their implication for both human health and the environment, while maintaining available resources: water, land and soil. The ultimate goal is to deepen scientific knowledge so that it can be of use to society;promoting food security through healthy and sustainable eating.
