ABSTRACT

Objective. To estimate the prevalence of suicidal ideation (SI) and the association with social determinants (SD) in the Mexican population during the Covid-19 pandemic. Materials and methods. Data from the survey of Distance Psychological Care for Mental Health were used due to the Covid-19 Contingency, obtained from 2020. Sample of 79 665. Logistic regression models were performed obtaining odds ratios (OR) with 95% confidence intervals (95%CI). Results. The prevalence of SI was 17.1% (women: 18.8%, men: 14.4%). The main associated SDs were: being a woman (OR = 1.11;CI95% 1.06,1.13), young women (OR = 1.30;CI95% 1.09,1.54), education (OR = 1.89;CI95% 1.14,3.12), single (OR = 1.31;CI95% 1.24,1.38), unemployment (OR = 2.33;CI95% 2.21,2.45), social distancing (OR 1.81;CI95% 1.68,1.96), living alone (OR 1.18;CI95% 1.10,1.27), loss of family member due to Covid-19 (OR = 1.41;95%CI 1.30,1.54), depression diagnosis (OR = 5.72;95%CI 5.41,6.05), physical violence (OR = 2.71;95%CI 2.49,2.95), excessive alcohol consumption (OR = 1.68;95%CI 1.58,1.79), drug use (OR = 3.13;95%CI 2.88,3.41) and suspicion or diagnosis of Covid-19 (OR = 1.79;95% CI 1.67-1.89). Conclusions. The prevalence of SI during the Covid-19 pandemic was high;the relevance of the structural and intermediate SD that influence SI is herein discussed © 2023, Salud Publica de Mexico.All Rights Reserved.

ABSTRACT

E-Learning education, Massive Online Open Courses (MOOCs) and Small Private Online Courses (SPOCs) have been ex-panding in the last decade. However, it increased in giant strides during the COVID-19 pandemic when the schools and universities did not have another option than to use remote education. Having a general understanding of E-Learning technology is not enough to implement an engineering virtual classrooms and laboratories. E-Learning standards are needed in all areas of E-Learning Systems such as online educational web applications, Learning Management Systems, and online labs, among others to gain interoperability, scalability, sustainability, security, privacy, and safety. The main objective of this paper is to discuss in general the current standards and technologies applied to E-Learning systems and analyze the need for a specific standards for Online Laboratory Management Systems (OLMS). © 2022 IEEE.

ABSTRACT

Purpose: Infection with COVID-19 has presented diversely in patients, including neuropsychiatric symptoms such as akinetic mutism. Most of these cases involve patients of middle-to-late age or with other health comorbidities. This is a unique case of a long hospitalization for severe catatonic symptoms in a patient with covid-19 infection in which ultimately, ECT helped produce rapid improvements in catatonia. Access to prompt ECT has been limited during the ongoing pandemic, and this case illustrates the importance of managing contamination risk and maintaining access to psychiatric treatment resources.

ABSTRACT

The pandemic has created an environment of considerable uncertainty, forcing companies to efficiently manage their resources to optimize their profits, prevent falling revenues, sustain the chain of payments and preserve employment. The objective of this research is to apply the Data Envelopment Analysis (DEA) method to know the financial impact of the COVID-19 crisis on Peruvian companies in the industrial sector, which are listed on the Bolsa de Valores de Lima. Multi-criteria model and correlation analysis were used for the validation of financial ratios, DEA method was used to evaluate efficiencies and Malmquist Productivity Index (MPI) to analyze changes in performance by quarter. Results indicate that 77% of companies are inefficient, equity items and administrative expenses are the most crucial for these companies to improve their performance;in addition, there is a deterioration of -31.5% in the total productivity of the sector mainly caused by the decrease in technological progress. This research offers decision-makers a tool that allows them to devise strategies to face the continuing financial crisis and promote investment in the use of technologies that may contribute to the improvement of productivity.

ABSTRACT

In recent years the application of deep learning algorithms in the subdomain of audio analysis has grown rapidly, however it is a topic that can be complex for students and researchers who have a first approach and want to develop an application in this field. The use of deep learning techniques applied to audio signals has allowed the development of a wide variety of useful tools in our daily lives, from virtual assistants to medical applications. This article presents a literature review of the main techniques that have been used in recent years for analysis, feature extraction and classification from audio spectra or spectrograms, as well as examples of application in the context of the COVID-19 pandemic in which multiple related projects have emerged, such as diagnostic systems. The techniques addressed are recurrent neural networks (RNN), convolutional neural networks (CNN) and generative adversarial networks (GAN). It is intended that the reader will be able to acquire this knowledge from a simple perspective and that this information will be useful in their research or development.

ABSTRACT

The great contagious capacity, the high pathogenic level of Sars-Cov-2 and the subsequent risk represented by physical contact between people, motivated measures such as social distancing and the closure of institutions, including university ones. In this way, many teachers who taught their classes in person, were faced with the need to educate from virtuality. However, a large proportion of these professionals did not have the technical preparation to approach this methodology, which includes the planning, preparation and execution of various demanding materials and activities that are added to the hours of synchronous virtual work, resulting in long hours. According to previous research, this has caused emotional exhaustion and physical exhaustion of the teacher. The present research proposed as an objective to analyze the levels of Burnout syndrome in university professors in Latin America, seeking to understand if these values are due only to the perception of these professionals or if, on the contrary, they are related to the risks and consequences of the covid-19 disease.

ABSTRACT

The main objective of the research was to try to see the perception of virtual classes and the possible academic repercussions that university students had in Peru, and their associated factors, during the COVID-19 pandemic. Analytical cross-sectional study in Peruvian university students during the first wave of the pandemic, the variable that mediates perception was obtained through a validated scale. In the analytical statistics, it was found that women had a higher frequency of perception of academic repercussions (PRa: 1.37;95% CI: 1.18-1.59;p value <0.001), this adjusted for age, study career and university. Women were the ones who perceived the most repercussions. Although an association was only found with the sex of the respondents, larger studies should be carried out and in more advanced stages of the pandemic, since our results can be taken as baseline, but the influence of others should be followed up and determine the influence of other variables.

ABSTRACT

One of the main causes of deterioration in mental health in the pandemic was the mishandling of information. The objective of this study was to evaluate the frequency of fear or perception of misinformation transmitted by the media and its influence on the mental health of the Peruvian population after the first wave. Analytical cross-sectional study. Which measured in almost 10,000 Peruvian inhabitants the perception of fear or exaggeration of the news with a previously validated instrument (global Cronbach's Alpha: 0.92), but this was post-first wave. The main perceptions were shown and it was associated with sex, age and educational level. Television broadcast more fear (12% strongly agree and 27% agree) and exaggeration (13% strongly agree and 26% agree);followed by social media. Men had a higher fear score in general (Coefficient: 1.83;95% CI: 1.01-3.31;p value = 0.047);Furthermore, according to the level of education, compared to those who had up to primary school, those who had secondary school had a higher overall score (Coefficient: 4.53;95% CI: 1.93-10.64;p value = 0.001), of exaggeration (Coefficient: 1.73;95% CI: 1.31-2.28;p value < 0.001), of fear (Coefficient: 1.73;95% CI: 1.31-2.28;p value < 0.001) and communication by friends / health personnel (Coefficient: 1.72;95% CI: 1.29-2.30;p value < 0.001);adjusted for age and department of residence. In general, it was observed that those with only secondary education were more afraid and were influenced by relatives and acquaintances.

ABSTRACT

Having been previously infected does not guarantee that one is safe in this pandemic, therefore, it is important to estimate the change in perceptions. The aim was to determine the fatalistic perception of patients recovered from COVID-19 in Peru and to identify the sociodemographic differences that influence the fatalistic perception of recovered and uninfected patients. Observational, retrospective cohort. The exposure variable was whether the patient had already been infected by COVID-19, the dependent variable was the fatalistic perception in the event of becoming ill with COVID-19 (in the case of those who had already been ill, the question was asked in the event of reinfection);this was measured with a validated test and being fatalistic was defined as those who were in the upper third of the scores;analytical statistics were obtained. Of the 8957 respondents, 37% reported that they had already been infected by COVID-19. In bivariate analysis, there was no difference in fatalism according to having been previously infected (p=0.426). In multivariate analysis, there was a lower risk of fatalism among men (aRR: 0.85;95%CI: 0.80-0.90;p-value<0.001), but an increased risk among those who believed they could be reinfected (aRR: 1.39;95%CI: 1.23-1.56;p-value<0.001), adjusted for three variables. Un conclusion, there is no association between fatalistic perception of the pandemic and having been infected with COVID-19 in Peru. However, being a woman and believing in a possible reinfection were risk factors for presenting fatalistic ideas.

ABSTRACT

The purpose of this study was to analyze the impetus that the pandemic caused by the new Covid-19 coronavirus will provide to the acceleration of the automation of the Port Logistics processes in the Port of Callao in Peru. The study was carried out from a qualitative approach, using the conceptual - inductive and phenomenological method as specific methods. Likewise, to collect the information, the in-depth interview technique applied to six specialists involved with the Port of Callao and its different operations was used. The information collected from the informants was developed through the synthesis and the Atlas.ti software. Regarding the investigative findings and conclusions, the pandemic has changed the way of conducting international business around the world, and a gap has opened in relation to the use of social networks, the internet and the tools that it brings with it. have become indispensable for this economic area, and also for the processes of exporting and importing goods and services, in the same way, to stop contagion and the spread of the virus, the governments of each country have adopted measures that have affected both producers as well as consumers.

ABSTRACT

Knowledge is key to face any disease, but there are few baseline studies from the beginning of the COVID-19 pandemic. The objective was to determine the association between being a vulnerable population and the low knowledge of the population in 17 Peruvian cities at the beginning of the pandemic. Knowledge was measured using a nine-question scale, which asks about the mechanism, symptoms and consequences;this was crosschecked against socio-demographic variables using analytical statistics. Of the 3913 respondents, the lowest knowledge was about how to react to cold symptoms and what treatment a person with an initial non-severe coronavirus infection should follow (37% and 53% correct answers;respectively). In the multivariate analysis, those who had lower percentages of a poor level of knowledge of the disease were those with higher education (aPR: 0.74;95%CI: 0.62-0.88;p-value=0.001), among those with some postgraduate studies (aPR: 0.59;95%CI: 0.43-0.68;p-value < 0.001), among those who were part of the health personnel (aPR: 0.15;95%CI: 0.05-0.46;p-value=0.001) and among women (aPR: 0.84;95%CI: 0.73-0.96;p-value=0.009), on the other hand, the older the age, the worse the level of knowledge of the disease (aPR: 1.012;95%CI: 1.005-1.018;p-value=0.001), adjusted by 4 variables. There was a low level of knowledge in some aspects and this is associated with some specific characteristics according to being considered a vulnerable population.

ABSTRACT

It has been observed that some groups of patients had the perception that if they fell ill from COVID-19 they could have greater complications. The aim of this study was to determine the association between fatalistic thinking about the possible infection of coronavirus according to the type of disease suffered by Peruvian patients. An analytical study of secondary data was carried out, which used a previous data to obtain respondents who had a disease (according to 9 groups/medical specialties), and cross-checked this according to fatalistic thinking (from a validated test). Of the 4483 respondents, 15% had a disease. Those with a respiratory disease perceived that they would be complicated post infection (p<0.001), also those with a cancer or tumor (p<0.001) or those with an endocrinological disease (p=0.002). Those who thought they would become depressed if they became ill were those with a respiratory (p=0.013) or gastroenterological disease (p=0.001). Those who perceived that they might die were those with a respiratory disease (p<0.001), those with any cancer or tumor (p=0.007), endocrinological (p<0.001) and neurological or psychiatric diseases (p<0.001). They could make a fatal decision upon learning of the infection are those who had an endocrinological disease (p=0.039). In conclusion, some groups of patients have a higher perception of getting sick, getting complicated, dying or even taking other fatal actions after learning that they have coronavirus infection;therefore, they should be given psychological support.

ABSTRACT

The pandemic caused many changes due to social distancing, one of them is in terms of virtual university classes. Therefore, the objective was to validate an instrument that measures the perception of the effects of COVID-19 on distance education in university students of health sciences and other careers in Peru. An instrumental and cross-sectional study was carried out. Thousands of distance learning students from health sciences and other careers participated during the first wave of the Coronavirus. The survey on the perception that it has of the repercussions caused by the health emergency on face-to-face and distance education was designed and validated;in addition, another scale was exploratory to measure the perception of the spread of the coronavirus. The analysis showed high reliability and good internal consistency, with adequate Cronbach's alpha values. For the Exploratory Factor Analysis (EFA), the Bartlett test and the Kaiser-Meyer-Olkin coefficient were used. All the items received a favorable evaluation by the experts (Aiken's V> 0.70);this with respect to relevance, representativeness and clarity. Three virtual average factors were identified, their use and presence, all saturation indices were greater than 0.50. The survey proved to be reliable and representative, this above all because it was evaluated in students from the different Peruvian departments;which can be used to evaluate this in diverse similar populations.

ABSTRACT

COVID-19 has generated an unprecedented pandemic. This scenario could affect the mental health of healthcare personnel, influencing their work performance with the possibility of leaving long-term sequelae. The objective was to determine the socio-occupational factors associated with suffering from anxiety, depression and stress in health professionals in the Peruvian highlands during the pandemic. Cross-sectional study. Doctors and other professionals at the Ramiro Priale Priale National Hospital in the Peruvian highlands were surveyed virtually. Depression, anxiety and stress were measured with the DASS-21 scale;these were associated with different socio-labour variables. More severe depression was found at older ages and if a family member had been ill at home, but less severe depression was found among those who had children, those who had more years of professional practice and those who had social security. Those who had children had less anxiety;less severe anxiety and those who had a relative away from home who became ill;on the other hand, those who worked more hours per day had more moderate anxiety, severe anxiety if the respondent had become ill and both types if a family member had died had more moderate anxiety. Those who worked more hours per day and those who had a deceased family member had more stress. The most relevant characteristics of health workers with mental health problems were older age, family history of COVID-19, history of death of a family member from COVID-19 and longer working hours.

ABSTRACT

In recent years, palm oil has been established as the most-produced oilseed oil in the world—its production volume has increased from 41 million tons in the 2007/08 season to more than 76 million tons in the 2018/19 season—and a crucial part of the Latin American agro-industrial sector. However, following a slowdown in export growth due to the 2020 COVID-19 lockdown, there is a vital need for sustainable expansion alternatives such as the production of value-added oil-palm products. This chapter presents the business process integration methodology and strategies pursued by a palm oil producer in Peru to optimize the vertical growth of its operational processes within the Latin American palm oil agro-industrial sector, based on the SAP S/4Hana Business Modules: Materials Management (for purchasing), Production Planning (for making), Sales and Distribution (for selling), Controlling (for tracking) and Human Capital Management (for managing staff). © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.

ABSTRACT

In the aftermath of the COVID-19 health crisis, hospitals around the world needed to stock up on resources to satisfy the high demand from patients. Peru was one of the countries most affected by the pandemic due to its fragile health system that led it to be the country with the highest mortality rate in the world with 554 deaths per million inhabitants. For this reason, it was imperative to implement measures to mitigate the state of emergency, such as the allocation of health resources to hospitals in all regions of the country. This research aimed to measure the efficiency of the Peruvian regions in the management of hospital resources against COVID-19 at the end of the year 2020. The two stage DEA model, the Data Envelopment Analysis in the first stage was used to estimate the efficiency and the Logit regression model in the second stage to find the incidence of internal and external factors. To this end, the variables number of doctors, number of nurses, oxygen, number of medications, number of COVID tests, number of positive cases, ICU beds available as inputs, and as outputs the mortality rate and recovery rate were selected;then, 8 models were formulated that grouped these variables sequentially to estimate efficiency. Results indicated that 53.33% of the regions were inefficient in all the proposed models, only Amazonas and Huancavelica regions were efficient in 2020, when comparing the average efficiency of each model, it was possible to distinguish that the internal variables of the number of nurses and oxygen causes a significant change in efficiency. Logit regression concluded that the number of nurses and the total population are significant influencing variables, while the external variable GDP per capita had a negative effect on the efficiency scores. Important findings show a notable deficiency in the use of human resources and poor management of investment in health resources to face the COVID-19 pandemic in Peru. © 2022 ACM.

ABSTRACT

Background. Worldwide SARS-CoV-2 infections increase every day. Despite the infection is less severe in children, it can be severe and associated with complications. However, local data remain scarce. We sought to describe epidemiological and clinical characteristics of COVID-19 infection in this population across different age groups. Methods. Observational, multicenter study across 23 Colombian hospitals from 22 different territories. We included all patients from 0 months to 17 years with confirmed SARS-CoV-2 infection by either antigen or RT-PCR testing. Results. From March 1, 2020, to October 31, 2021, we identified 1,186 patients: neonates (88), 1 to 3 months (130), 4 to 23 months (306), 2 to 4 years (169), 5 to 11 years (229) and 12 to 18 years (226) with confirmed COVID-19 infection. Of those,77(6.2%) were asymptomatic, 631(53.2%) hospitalized, 132(11.2%) required PICU. 58 cases met WHO definition of MIS-C. Patients less than 24 months of age were characterized by fever (74%) and more respiratory distress (30.1%) compared to other groups. Patients >5yo seemed to have a more severe presentation. They had more gastrointestinal (GI) symptoms (31% vs 37.8%), had more need for ICU care given presentation with shock increased with age ( >5yo 9.5%;5-12yo 10.6%;12-18yo 11.5%). Lab markers including thrombocytopenia and Lymphopenia were more common on this age group. Antibiotic treatment was common (%%) especially in neonates (40.9%), despite bacterial coinfection was rare (8.7%), length of hospitalization was longer in older than 2-year-old groups. 23(1.9%) patients died, similar across different age groups. Conclusion. COVID-19 infection in Colombian children presented differently across different age groups. Children older than 5 years had a more severe clinical course and prolonged hospital stays. Clinical findings according to age groups could help clinicians in characterizing and identifying COVID 19 infections in Children.

ABSTRACT

Before the pandemic, the United Nations Sustainable Development Goals included cutting learning poverty in half by 2030. The COVID-19 pandemic has had severe negative impact on education throughout the world and set back progress toward this goal. Science, Technology, Engineering and Mathematics (STEM) education include laboratory experiences. Engineering and Technology program Accreditation Agencies deem labs critical to an engineer's education and require it in the criteria for international accreditation. While converting traditional instruction to virtual instruction posed a challenge to all, developing countries faced higher constraints of limited bandwidth, connectivity, and household access to technology. Once the access problems are resolved, universities still have the challenge of providing inclusive access to online laboratory experiments, particularly for engineering students. This paper presents current solutions for online Engineering laboratories and proposes an online lab management system and a federated lab model appropriate for developing countries that the Latin American and Caribbean Consortium of Engineering Institutions (LACCEI) is currently developing and piloting. © 2021 IEEE.

ABSTRACT

The COVID-19 pandemic caused various effects in the world, among them the saturation of information in the traditional media, as well as in those of scientific dissemination, due to the accelerated production of informative material. At the Mexican Institute for Social Security (Instituto Mexicano del Seguro Social), librarians have contributed to the careful selection of documents as they are in charge of providing specialized information services to health personnel in order to support them in academic, educational, teaching and research activities. In the context of physical distancing, the need for up-to-date and accurate information on the new coronavirus became a priority. In this sense, librarians have focused their efforts to carry out strategies that would allow to provide specialized information services remotely, reinforcing reference services such as bibliographic alert and Selective Information Dissemination, to reach users in a timely manner, simple and agile, updated, reliable and quality information on COVID-19. These services have been well received by users, but it is still necessary to systematize the provision of information services to identify which documents are of greatest interest and usefulness.
