Role of technology in motivating the graduate students in conducting research amidst the Covid-19 pandemic

Technology is already widely used in graduate school, especially in this new normal. Textbooks and references are reliable sources of reference materials while doing research;however, due to the pandemic, technology should be used to deliver the content of graduate school courses. However, not all graduate students have the motivation to conduct research. Thus, this study looked into the role of technology in motivating the students in the graduate studies in conducting research. This study employed the qualitative research approach and the convenience sampling was utilized to elicit the participants' perspectives on the role of technology in motivating graduate students in conducting research amidst the Covid-19 pandemic. An unstructured survey questionnaire was distributed to ten participants via google link. The findings were evaluated and interpreted in view of the documentary analysis. It has been discovered that there was a great impact of the role of technology in the graduate students to be motivated in conducting a research. Majority of the respondents believed that the use of technology paly a vital role in the conduct of research. This makes their life simpler and easier when supported with various technological tools, support from the adviser and the institution. The drawbacks, on the other side, can be utilized to strengthen the technological techniques of both professors and students in order to increase the motivation of the graduate students in their research writing. It was also found out that the graduate students are more motivated to conduct a study when they are provided with the library resources, support from the adviser, and support from the management or the institution. The research further suggests the potential solutions to the graduate students' problems through the use of themes that will form part of the role of technology in motivating the graduate students to do their thesis writing. This implies that technology has a greater impact in motivating the graduate students to write their thesis writing based on the result of the study. © 2023 Author(s).

Improving Access to Extracranial-Intracranial Bypass Surgery in Border Hispanic Communities Utilizing Collaborative Approach Between Plastics and Neurological Surgery

INTRODUCTION: Hispanic patients such as those with Moyamoya disease are less likely to receive surgical revascularization therapy due to inequities in access (1). Our institution is a located in the Southern Texas- Mexico border region serving a largely Hispanic population. We previously referred patients for EC-IC bypass to other quaternary-care centers in Texas. While referrals were already challenging due to distance, mixed immigration status, and poor socioeconomic background of many patients;COVID-19 further exacerbated this problem with restriction of elective surgical volume. METHOD(S): A consecutive series of EC-IC bypasses performed by authors (SKD and MDLG) were retrospectively reviewed. Baseline clinical, perioperative radiographic, and post-operative outcomes were studied. All patients were offered option of a referral to a quaternary-care centers and also given local option for performing bypass surgery. Further, patients met preoperatively with both the plastic and neurological surgeon. Ultimately, decision was made by patient. RESULT(S): A total of 6 craniotomies for EC-IC bypass were performed during the study period. The diagnoses included Moyamoya in 5 cases and symptomatic intracranial atherosclerosis in one. All patients were Hispanic, female, and nonsmokers with mean age of 35.6 years. Mean preoperative HBa1c was 7.9, preoperative LDL was 82, and mean preoperative hemoglobin was 11.3. Direct bypass was performed in 40% of cases. Mean OR time was 3 hours and 7 minutes. CONCLUSION(S): We have found collaboration between plastic and neurological surgery for surgical revascularization is feasible and improved access to care for Hispanic Moyamoya disease patients residing in a border community.

COVID-19: prevention, diagnosis and treatment. Recommendations of a multidisciplinary group.

BACKGROUND: SARS-CoV-2 infection, which causes COVID-19, has impacted the entire world due to its extensive and rapid spread. In the last two years, more than 412 million cases have been confirmed, with more than 5.8 million deaths, as of February 14, 2022. OBJECTIVE(S): Integrate a series of recommendations based on the best level of evidence in prevention, diagnosis and treatment of SARS-CoV-2 infection, including its new variants. METHODOLOGY: Review of different international guidelines and recent articles published in peer-reviewed journals. Issue recommendations based on the level of evidence and degree of confirmation established by the guidelines of the National Institute for Health and Care Excellence (NICE). The authors analyzed the selected articles and, based on their experience, summarized the most relevant to meet the objectives of these recommendations. RESULT(S): 200 articles were found, of which only 124 were selected that met the requirements to identify the level of evidence and degree of recommendation. CONCLUSION(S): Prevention through vaccination continues to be the best tool to establish protection mechanisms against the virus and substantially reduce hospitalizations and associated mortality. Although homologous vaccination is still the accepted reference pattern, the efficacy of heterologous schemes to avoid hospitalization and mortality must be considered. Monoclonal experiments, such as sotrovimab, have activity against the Omicron variant and the AZD7442 molecule that have shown high efficacy in preventing symptomatic COVID-19 in pre- and post-exposure conditions.Copyright © 2022 Comunicaciones Cientificas Mexicanas S.A. de C.V..

Clinical profile of hospitalized spanish patients allergic to antibiotics

Background: Only between 1% and 10% of patients labelled of penicillin allergy are allergic. The negative events associated with this condition include risk of antimicrobial treatment failure, antimicrobial resistance, side-effects from use of a broader spectrum antibiotic, and increased healthcare costs. Our objective was to know the clinical profile of hospitalized allergic patients to estimate the future need for an allergy study. Method(s): We collected data from 15 Spanish hospitals about hospitalized patients labelled as allergic to antibiotics in February 2020 and October 2020 (one-month sample) outside the peak of the Covid-19 pandemic. Result(s): 620 patients were collected, 59% women. Mean age 70.6 years (3-103). 416 patients were labelled as allergic to beta-lactams (105 aminopenicillins, 18 cephalosporins, 4 carbapenems). 41 to aminoglycosides, 26 to macrolides, 55 to quinolones and 4 to glycopeptides. The causes of hospitalization were: Respiratory infection 221 (35.6%), abdominal infection 95 (15.3%), orthopaedic surgery 58 (9.4%), urine infections 57 (9.2%), skin infections 51 (8.2%), gynaecological/ obstetric pathology 21 (3.4%) Only 163 patients (26%) had previously received a clinical allergy work-up. 70 confirmed allergy to antibiotics, however the rest 93 (74%) were not delabelled. Patients received alone or combined alternative antibiotics: 79 glycopeptides, 49 aminoglycosides, 28 macrolides, 254 quinolones, 205 beta-lactams (102 cephalosporins, 41 carbapenems and 57 aminopenicillins). 74 patients (12%) would need an immediate allergic study in order to receive first-line antibiotic, but it was only really done in 38 (6.1%). The studied antibiotics were: 15 carbapenems, 10 ceftriaxone, and others not specified. Of the 416 patients labeled as allergic to beta-lactams, 150 (36%) received beta-lactam antibiotics despite the warning in their clinical reports. Conclusion(s): Allergy to beta-lactams remains the most frequent diagnosis of allergy to antibiotics and implies treatment with second-line antibiotics. Respiratory, trauma, digestive and urinary infections are the main causes of the use of antibiotics in hospitalized patients. The underlying diseases could be a risk factor for antibiotic requirements. Some patients received beta-Lactams despite the alert with a potential risk of an allergic reaction and legal implications. The promptly allergological study would imply an improvement in the use of more specific antibiotics with a good level of security.

Cardiovascular features and risk of mortality in COVID-19 hospitalized patients in Spain during 2020. A nationwide study from the Minimum Basic Data Set

Introduction: During the last two years scientific evidence has been gathered regarding the cardiovascular complications of Covid-19. Nevertheless nationwide studies are still required to better understand both the incidence of less frequent clinical findings, and the prognostic implications of cardiovascular COVID-19 complications. Purpose(s): The aim of this study was to estimate the incidence of cardiovascular diseases among COVID-19 hospitalized patients in Spain during 2020, as well as their association with mortality, besides other clinical and epidemiological factors. Method(s): We used the Minimum Basic Data Set from the Spanish Ministry of Health (RAE-CMBD) to analyze the data of all COVID-19 hospitalized patients in Spain during 2020. This national database includes concurrent diagnostics of all studied patients codified according to the Tenth International Classification of Diseases (ICD-10). Logistic regression analysis was performed to evaluate the influence of the different clinical and epidemiological variables in the evolution of COVID-19 hospitalized patients. Odds ratios were obtained for each variable adjusting by age and sex, and also adjusting by the rest of clinical factors. The software used for analysis was STATA v 16.1. Result(s): 75585 men (55.15%) and 61468 women (44.85%) were hospitalized due to COVID-19 during 2020 in Spain. The median age was 66 in men and 71 in women. Mortality was 14.92% in males, and 13.81% in females. 9.62% of patients were admitted to intensive care unit (ICU). Mortality in ICU was 29.13%. Heart Failure (7.8%), Atrial Fibrillation (7.7%), Pulmonary Embolism (3.46%), Supraventricular Arrythmias (1.18%), Cardiomyopathy (1.06%), Acute Coronary Syndrome (0.87%), Ischemic Stroke (0.33%), Myocarditis (0.12%) Pericarditis (0.06%), or Takotsubo Disease (0.05%), were relevant cardiovascular findings in COVID-19 hospitalized patients (Table 1). In the logistic regression multivariate analysis in COVID-19 patients we found epidemiological predictors of in-hospital mortality such as age (OR 2.38 for each decade), or male sex (OR 1.39). Among the clinical predictors of mortality we differentiated cardiovascular ones as Acute Coronary Syndrome (OR 1.51), Ischemic Stroke (OR 1.46), or Heart Failure (OR 1.43);and non cardiovascular ones such as admission to ICU (OR 3.12), Adult Respiratory Distress Syndrome (OR 2.74), need for Mecanical Ventilation (OR 2.52), Acute Kidney Failure (OR 2.07), Liver damage (OR 1.67), or Dementia (OR 1.66), (Table 2) Conclusion(s): Heart Failure, Pulmonary Embolism, Ischaemic Heart Disease, Atrial fibrillation, Ischemic Stroke, or Cardiomyopathy were among the main cardiovascular diseases associated to COVID-19. They increased in a different measure the risk of mortality in COVID-19, together with factors such as Mecanical ventilation, ICU admission, Acute kidney failure, Dementia, Liver damage, Adult Respiratory Distress Syndrome, older age, or male sex.

Multidisciplinary approach of the sequelae one month after hospital discharge in patients with severe bilateral COVID-19 pneumonia, are there differences depending on the respiratory therapy used during admission to intensive care?

OBJECTIVE: To describe the sequelae one month after hospital discharge in patients who required admission to Intensive Care for severe COVID 19 pneumonia and to analyze the differences between those who received therapy exclusively with high-flow oxygen therapy compared to those who required invasive mechanical ventilation. DESIGN: Cohort, prospective and observational study. SETTING: Post-intensive care multidisciplinary program. PATIENTS OR PARTICIPANTS: Patients who survived admission to the intensive care unit (ICU) for severe COVID 19 pneumonia from April 2020 to October 2021. INTERVENTIONS: Inclusion in the post-ICU multidisciplinary program. MAIN VARIABLES OF INTEREST: Motor, sensory, psychological/psychiatric, respiratory and nutritional sequelae after hospital admission. RESULTS: 104 patients were included. 48 patients received high-flow nasal oxygen therapy (ONAF) and 56 invasive mechanical ventilation (IMV). The main sequelae found were distal neuropathy (33.9% IMV vs 10.4% ONAF); brachial plexopathy (10.7% IMV vs 0% ONAF); decrease in grip strength: right hand 20.67kg (±8.27) in VMI vs 31.8kg (±11.59) in ONAF and left hand 19.39kg (±8.45) in VMI vs 30.26kg (±12.74) in ONAF; and limited muscle balance in the lower limbs (28.6% VMI vs 8.6% ONAF). The differences observed between both groups did not reach statistical significance in the multivariable study. CONCLUSIONS: The results obtained after the multivariate study suggest that there are no differences in the perceived physical sequelae one month after hospital discharge depending on the respiratory therapy used, whether it was high-flow nasal oxygen therapy or prolonged mechanical ventilation, although more studies are needed to be able to draw conclusions.

Influence of epidemiological and clinical factors in the reactogenicity to Comirnaty® vaccine in health care workers of a Spanish university teaching hospital (COVIVAC study).

OBJECTIVE: Comirnaty® is an mRNA vaccine against COVID-19 which has been administered to millions of people since the end of 2020. Our aim was to study epidemiological and clinical factors influencing reactogenicity and functional limitation after the first two doses of the vaccine in health care workers (HCWs). METHODS: Prospective post-authorization cohort study to monitor safety and effectiveness of the vaccine. RESULTS: Local side effects were mild and presented both with first and second dose of Comirnaty. Systemic side effects were more frequent after 2nd dose. Nevertheless, previous SARS-CoV-2 infection was associated with systemic effects after the first dose of the vaccine (OR ranging from 2 to 6). No severe adverse effects were reported. According to multivariate analysis, the degree of self-reported functional limitation after the first dose increased with age, female sex, previous COVID-19 contact, previous SARS-CoV-2 infection, and Charlson Comorbidity Index (CCI). After the second dose, the degree of functional limitation observed was lower in those with previous SARS-CoV-2 infection, and it was positively associated to the degree of functional limitation after the first dose. CONCLUSIONS: Systemic adverse effects were more frequent after the second dose of Comirnaty. Previous SARS-CoV-2 infection was associated with systemic effects after the first dose. Age, female sex, previous COVID-19, previous isolation due to COVID-19 contact, and CCI showed to be independent predictors of the degree of functional limitation after the 1st dose of Comirnaty®. After the 2nd dose, the degree of functional limitation was lower in those who previously had SARS-CoV-2 infection.

Three Mathematical Models for COVID-19 Prediction

The COVID-19 outbreak was a major event that greatly impacted the economy and the health systems around the world. Understanding the behavior of the virus and being able to perform long-term and short-term future predictions of the daily new cases is a working field for machine learning methods and mathematical models. This paper compares Verhulst's, Gompertz´s, and SIR models from the point of view of their efficiency to describe the behavior of COVID-19 in Spain. These mathematical models are used to predict the future of the pandemic by first solving the corresponding inverse problems to identify the model parameters in each wave separately, using as observed data the daily cases in the past. The posterior distributions of the model parameters are then inferred via the Metropolis–Hastings algorithm, comparing the robustness of each prediction model and making different representations to visualize the results obtained concerning the posterior distribution of the model parameters and their predictions. The knowledge acquired is used to perform predictions about the evolution of both the daily number of infected cases and the total number of cases during each wave. As a main conclusion, predictive models are incomplete without a corresponding uncertainty analysis of the corresponding inverse problem. The invariance of the output (posterior prediction) with respect to the forward predictive model that is used shows that the methodology shown in this paper can be used to adopt decisions in real practice (public health). © 2023 by the authors.

Trends in COVID-19-related in-hospital mortality in women and men.

Introduction: Whether political, scientific and medical development in a country is associated with better clinical results according to gender in patients with COVID-19 has not yet been clearly elucidated. Objective(s): To determine the trends of COVID-19-related in-hospital mortality in women and men from March 2020 to February 2022. Method(s): Clinical data of all patients with COVID-19 cared for at 21 Spanish hospitals were used, both of those who were discharged and of those who died during hospitalization. The association between hospital length of stay and mortality was analyzed with logistic regression models. Result(s): Out of 7,974 patients that were included, 3,234 were women;928 patients died. A significant decreasing trend in mortality was identified. When the analysis was carried out by gender, no significant mortality trend was found in women (OR = 0.96 [0.90-1.03], p = 0.239), while in men there was a significant decreasing trend identified (OR = 0.87 [0.820.92], p < 0.001). Conclusion(s): Health policies, together with clinical and preventive interventions, may explain these results. Response to treatment and behavioral differences may explain why mortality does not decrease for women.Copyright © 2022 Academia Nacional de Medicina de Mexico, A.C. Publicado por Permanyer.

Application of classical and advanced machine learning models to predict personality on social media

Knowing personality traits and how people tend to think, feel and behave has been always an appealing and studied topic. This interest together with the vast amount of data generated every day on social networks present an ideal scenario to address this problem. By properly processing this data, it could be useful for many aspects of people's daily life. In this study, we applied different Machine Learning methods to solve this problem using a dataset labelled with the MBTI personalities, and we compared several algorithms such as Naïve Bayes, Logistic Regression and three different Artificial Neural Networks. Two main experiments were conducted. First, a clustering-oriented solution. Second, a classification approach. The latter turned out to outperform the clustering methods. On average, our models achieved around 90% accuracy. Finally, in order to show an example of our solution, we will validate our model with the latest news about COVID-19 and the La Palma Volcano. © 2023 Elsevier Ltd

Incidence, morbidity and mortality, and management of acute coronary syndrome during the time of COVID-19 lockdown

Introduction and objectives: During the lockdown due to the pandemic caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), a decrease in the number of admissions due to acute coronary syndrome (ACS) was observed. The objective of our study was to evaluate the impact lockdown had on the incidence, morbidity and mortality, and management of ACS. Methods: A retrospective and multicenter study was conducted including patients admitted due to ACS from February 14 through June 24, 2020. Patients with acute myocardial infarction and coronary arteries without significant lesions were excluded. The following groups were established based on the period of admission: a) 1 month before lockdown;b) during lockdown;and c) 1 month after lockdown. The differences in mortality seen among the 3 groups were evaluated, as well as the temporal differences reported between symptom onset and the first medical contact (FMC). Results: a total of 634 patients were included (group a, 205;group b, 303, and group c, 126). A 41% decrease in the number of admissions due to ACS was observed during the first month of lockdown compared to the previous month, as well as diagnostic delay during this same period (group a, 66 minutes (45-180), group b, 120 minutes (60-240), and group c, 120 minutes (60-240), P =.007). However, a higher mortality rate during confinement was not reported (RR, 1.26;95%CI, 0.53-2.97;P =.60). Conclusions: During lockdown, a remarkable decrease in the number of admissions due to ACS was observed, and although there was an increase in the time elapsed from symptom onset to the FCM in this period in patients with STEMI, the mortality rate was similar in the 3 groups studied.

Digital communication in the olive sector: The case of the olive mills in the province of Jaén

Recent events such as COVID-19 and the conflict in Ukraine have increased the de-mand for olive oil, a key product in the Spanish agri-food system due to its history and foreign trade. Jaén accounts for 37% of national production. Through content analysis, the websites of the 74 olive oil mills in this province were investigated to identify the distinctive elements of their digital communication and the way they connect with their audiences. The results indicate that this is a traditional and con-servative sector that is starting to go digital, mainly through its presence on social networks. © GKA Ediciones, authors.

COVID-19 and social media

The COVID-19 pandemic has challenged the world and changed our lifestyle in many aspects. From the discovery of the new virus and the clinical presentation of the associated illness, many news have flooded our media and caused significant attention from the public. The rapid spread of the disease is only comparable to the accelerated appearance of news populating traditional media channels as well as social media portals. The concern for the public, the medical professionals, and the governments around the world has been the truthfulness, accuracy, and verification of the information transmitted. A call for regulations has been made by some, while others advocate for a complete freedom of speech and information. The basic concepts of true journalism as well as the interest in the manipulation of the information are suddenly colliding into a different battlefield and have created on their own a different form of pandemic, the infodemic. © 2022 Elsevier Inc.

Comparison of different field tests to assess the physical capacity of post-COVID-19 patients.

BACKGROUND: In coronavirus disease (COVID-19), physical capacity is one of the most impaired sequelae. Due to their simplicity and low cost, field tests such as the six-minute walk test (6MWT) are widely used However, in many places it is difficult to perform them and alternatives can be used such as the 1 min sit-to-stand test (1min-STST) or the Chester step test (CST). Therefore, our objective was to compare the 6MWT, 1min-STST and the CST in post-COVID-19 patients. METHODS: We conducted a cross-sectional analysis in post-COVID-19 patients, compared with matched controls (CG). Demographic characteristics and comorbidities were collected. We analysed oxygen saturation (SpO2), heart rate (HR), and the modified Borg scale in the 6MWT, 1min-STST, and CST. Additionally, the correlations between tests were analysed. RESULTS: We recruited 27 post-COVID-19 patients and 27 matched controls. The median age was 48 (IQR 43-59) years old (44% female). The median distance walked in 6MWT was 461 (IQR 415-506) m in post-COVID-patients and 517 (IQR 461-560) m in CG (p = 0.001). In 1min-STST, the repetitions were 21.9 ± 6.7 and 28.3 ± 7.1 in the post-COVID-19 group and CG, respectively (p = 0.001). In the CST, the post-COVID-19 group performed 150 (86-204) steps vs the CG with 250 (250-250) steps (p < 0.001). We found correlations between the 6MWT with the 1min-STST in COVID-19 patients (r = 0.681, p < 0.001) and CG (r = 0.668, p < 0.001), and between the 6MWT and the CST in COVID-19 patients (r = 0.692, p < 0.001). CONCLUSION: The 1min-STST and the CST correlated significantly with the 6MWT in patients post-COVID-19 being alternatives if the 6MWT cannot be performed.

International students and learning experiences in higher education

The COVID-19 pandemic has caused major disruptions to several industries including higher education. Malaysia has attempted to be a hub of educational excellence by transforming its higher education, thereby attracting international students as key drivers to its economy and internationalization. This study aims to identify the current challenges international students have faced due to the pandemic and proposes solutions to tackle those challenges. The data for this study was collected qualitatively through focus group interviews using a purposive sample of students, administrative, and academic staff of two universities in Malaysia. Data was collected between October 2020 and January 2021, covering the COVID situation for the whole of year 2020 to reflect the experiences of the international students. The results indicate that the students have some major concerns as a result of numerous academic, administrative, social, financial, and emotional challenges they have been facing. Addressing the challenges and concerns is of great importance in ensuring the sustainability of keeping universities in Malaysia appealing destinations to international students. The research proposes some solutions for improving the current situation in light of the findings of the study. © 2022 selection and editorial matter, Sheena Kaur, Prasana Rosaline Fernandez, and Ali Jalalian Daghigh.

Household Awareness and Participation on Waste Disposal: An Effective Solid Waste Management Amidst COVID-19 Pandemic

This research aims to determine the demographics that affect the solid waste management behavior in San Martin Subdivision in Angono, Rizal, conducted during the time of pandemic. This aims to improve sustainability and help create programs that will improve the participation of the households towards positive waste management. Currently, there are limited studies involving waste management, especially in developing countries like the Philippines, where waste management problems are more prevalent, adding more solid wastes during the pandemic period. This will help developing countries improve their waste management system as it will open areas for research and development. The researchers seek through the study of the demographics that affects the attitude, knowledge, and practices of the households to create a more targeted solution for the area. Online questionnaires were distributed to the respondents and were analyzed using the Kruskal-Wallis test. The findings revealed the relevant demographics in the target area and created a conceptual framework that the administrators can adopt. For the knowledge, attitude, and practice of the households, the income of the family showed significance. The other significant demographics were the household size for the attitude section;educational attainment for the knowledge section;and all the demographics for the practice section. Knowing this relevance, the community can create policies that are catered more to the effective group equating to greater chance of success in the implementation. The significance of the study is that the household wastes comprise of more than half of the waste generation of the Philippines hence, targeting this sector of the society will greatly impact the solid waste problem in the country. © 2021 IEEE.

The incidence, risk factors and impact of acute kidney injury in hospitalized patients due to COVID-19

The incidence of acute kidney injury (AKI) in hospitalized patients with COVID-19 is variable, being as- sociated with worse outcomes. The objectives of the study were to evaluate the incidence, risk factors (considering demographic characteristics, comorbidities, initial clinical presentation and associated complications) and impact of AKI in subjects hospitalized for COVID-19 in two third-level hospitals in C..rdoba, Argentina. A retrospective cohort study was conducted. We included 448 adults who were consecutively hospitalized for COVID-19 between March 3 and October 31, 2020 and were followed throughout the hospitalization. The incidence of AKI was 19% (n = 85;stage I = 43, stage II = 17, and stage III = 25, 18 required renal replacement therapy). In the multivariate analysis, the variables that were independently associated with AKI were: age (for every 10 years, adjusted odd ratio [95%CI] = 1.30 [1.04-1.63], p = 0.022), history of chronic kidney disease -CKD- (9.92 [4.52-21.77], p < 0.001), blood neutrophil count at admission -BNCA- (for every increase of 1000 BNCA, 1.09 [1.01-1.18], p = 0.037) and requirement for mechanical ventilation -MV- (6.69 [2.24-19.90], p = 0.001). AKI was associated with longer hospitalization, higher admission (63.5 vs. 29.7%;p < 0.001) and longer stay in the intensive care unit, a positive association with respiratory bacterial superinfection, sepsis, respiratory distress syndrome, MV requirement and mortality (mortality without AK I = 12.4% vs with AKI = 47.1%;stage I = 26%, stage II = 41% and stage III = 88%;p < 0.001). AKI was independently associated with higher mortality (3.32 [1.6-6.9], p = 0.001). In conclusion, the incidence of AKI in adults hospitalized for COVID-19 was 19% and had a clear impact on morbidity and mortality. The independent risk factors for AKI were: Age, CKD, BNCA and MV.

SARS-CoV-2 Infection in a Referral Cancer Center in Mexico City during the First Year of the COVID-19 Pandemic

Background. Literature on SARS-CoV-2 infection in cancer patients is scarce in Latin America. This population seems to have a higher risk for adverse outcomes. This study aims to correlate clinical characteristics with outcomes in patients with cancer in a referral center in Mexico. Methods. We included patients with cancer and confirmed SARS-CoV-2 infection, from April, 19 to December 30, 2020, at the Instituto Nacional de Cancerologia, Mexico. Clinical information was obtained from medical and epidemiological records. We conducted a descriptive analysis. For the association between variables with hospitalization, invasive mechanical ventilation (IMV), and mortality;univariate and multivariate logistic regression was performed;odds ratios and 95% confidence intervals were calculated. Results. Four hundred thirty-three patients were included;268 (62%) were female, the median age was 55 years. One hundred thirty-five (31%), 130 (30%), and 93 (21%) patients had obesity, hypertension, and diabetes mellitus (DM), respectively. Three hundred forty-one (79%) had solid cancer;82 (19%) hematological malignancy (HM), and 10 (2%) were under evaluation for cancer diagnosis. One hundred seventy (39%) had advanced or metastatic cancer. One hundred ninety-eight (46%) patients were hospitalized. Risk factors were: age (p= 0.001);woman (p=0.019);HM (p=0.050) and advanced or metastatic cancer (p= 0.041). Fourty-five (10%) patients required IMV. Age (p=0.018);DM (p=0.041);C-Reactive Protein (p= 0.002), and LDH (p= 0.033) were associated with invasive mechanical ventilation. Mortality within 30-days after diagnosis was 19% (82 cases). Associated characteristics were: age (p=0.041);lymphocytes (p=0.049);creatinine (p=0.005) and albumin (p=0.001). Conclusion. In this study, patients with cancer showed higher mortality, need of hospitalization, and invasive mechanical ventilation compared with groups of patients without cancer. We did not find an increased risk in mortality for hematological malignancies. Although our cohort was younger than others previously reported, age was a strong predictor of adverse outcomes. Variables associated with IMV and death were similar to those previously described in cancer patients with COVID-19.
