Parenting practices as a buffer in the relationship between exposure to community violence and bullying in Mexican adolescents.

Multiple studies have shown that adolescents exposed to community violence are likely to engage in bullying behaviors. However, we still need to understand which variables can help reduce the influence of community violence exposure (CVE) on bullying. To investigate this question, a study was conducted with a sample of 568 Mexican adolescents, comprising 276 (48.6%) males and 292 (51.4%) females aged 12 to 16 years old (M age = 13.7 years, SD = 0.82). The study examined how parental support (PS) and parental induction to justice sensitivity (JS) can moderate the relationship between CVE and bullying. The study used structural equation modeling with latent variables. The results showed that CVE was positively associated with bullying, whereas PS and the induction to perpetrator JS were negatively associated. The moderation analysis suggests that the relationship between CVE and bullying was weaker among adolescents who received high PS. On the other hand, low and high parental induction to JS had the same moderating effect. Based on the findings, parental practices are critical when developing preventive programs to reduce the harmful effects of CVE on bullying behavior.

Restorative Parental Discipline and Types of Defending Bystander Intervention in Cyberbullying: The Mediate Role of Justice Sensitivity.

Parental socialization strategies are critical in explaining adolescents' online behavior. This study examined the relationships between parental restorative discipline, observed justice sensitivity, and cyber-bystander defender intervention (constructive and aggressive) in cyberbullying. The sample comprised 900 Mexican adolescents (40.2% male and 58.8% female), of which 450 were from secondary school (M age = 13.6, SD = 0.8) and 450 were from high school (M age = 15.4, SD = 1.3). Structural equation modeling with latent variables was performed. Overall, the results indicate that parental restorative discipline positively relates to the observer's justice sensitivity and the adoption of constructive interventions by cyber-bystander defenders. However, restorative discipline had no significant direct relationship with aggressive intervention. Observers' justice sensitivity mediates the association between restorative parenting discipline and aggressive or constructive defender interventions. Gender does not moderate the relationship proposed in the structural model. These findings suggest that parental restorative discipline explains constructive and aggressive cyber-bystander defender interventions in cyberbullying.

Use of portable single-lead electrocardiogram device as an alternative for QTc monitoring in critically ill patients.

PURPOSE: Acquired QT prolongation is frequent and leads to a higher mortality rate in critically ill patients. KardiaMobile 1L® (KM1L) is a portable, user-friendly single lead, mobile alternative to conventional 12-lead electrocardiogram (12-L ECG) that could be more readily available, potentially facilitating more frequent QTc assessments in intensive care units (ICU); however, there is currently no evidence to validate this potential use. METHODS: We conducted a prospective diagnostic test study comparing QT interval measurement using KM1L with conventional 12-L ECG ordered for any reason in patients admitted to an ICU. We compared the mean difference using a paired t-test, agreement using Bland-Altman analysis, and Lin's concordance coefficient, numerical precision (proportion of QT measurements with <10 ms difference between KM1L and conventional 12-L ECG), and clinical precision (concordance for adequate discrimination of prolonged QTc). RESULTS: We included 114 patients (61.4% men, 60% cardiovascular etiology of hospitalization) with 131 12-L ECG traces. We found no statistical difference between corrected QT measurements (427 ms vs. 428 ms, p = .308). Lin's concordance coefficient was 0.848 (95% CI 0.801-0.894, p = .001). Clinical precision was excellent in males and substantial in females (Kappa 0.837 and 0.781, respectively). Numerical precision was lower in patients with vasoactive drugs (-13.99 ms), QT-prolonging drugs (13.84 ms), antiarrhythmic drugs (-12.87 ms), and a heart rate (HR) difference of ≥5 beats per minute (bpm) between devices (-11.26 ms). CONCLUSION: Our study validates the clinical viability of KM1L, a single-lead mobile ECG device, for identifying prolonged QT intervals in ICU patients. Caution is warranted in patients with certain medical conditions that may affect numerical precision.

Adherence to Treatment Guidelines in Ambulatory Heart Failure Patients with Reduced Ejection Fraction in a Latin-American Country: Observational Study of the Colombian Heart Failure Registry (RECOLFACA).

INTRODUCTION: Although several guidelines recommend that patients with heart failure with reduced ejection fraction (HFrEF) be treated with angiotensin-converting enzyme inhibitors/angiotensin II receptor blockers (ACEIs/ARBs) or angiotensin receptor-neprilysin inhibitors (ARNIs), beta-blockers, mineralocorticoid receptor antagonists (MRAs), and sodium-glucose cotransporter-2 inhibitor (SGLT2i), there are still several gaps in their prescription and dosage in Colombia. This study aimed to describe the use patterns of HFrEF treatments in the Colombian Heart Failure Registry (RECOLFACA). METHODS: Patients with HFrEF enrolled in RECOLFACA during 2017-2019 were included. Heart failure (HF) medication prescription and daily dose were assessed using absolute numbers and proportions. Therapeutic schemes of patients treated by internal medicine specialists were compared with those treated by cardiologists. RESULTS: Out of 2,528 patients in the registry, 1,384 (54.7%) had HFrEF. Among those individuals, 88.9% were prescribed beta-blockers, 72.3% with ACEI/ARBs, 67.9% with MRAs, and 13.1% with ARNIs. Moreover, less than a third of the total patients reached the target doses recommended by the European HF guidelines. No significant differences in the therapeutic schemes or target doses were observed between patients treated by internal medicine specialists or cardiologists. CONCLUSION: Prescription rates and target dose achievement are suboptimal in Colombia. Nevertheless, RECOLFACA had one of the highest prescription rates of beta-blockers and MRAs compared to some of the most recent HF registries. However, ARNIs remain underprescribed. Continuous registry updates can improve the identification of patients suitable for ARNI and SGLT2i therapy to promote their use in clinical practice.

Seroprevalence and coprological prevalence of liver fluke Fasciola hepatica in cattle and sheep from Santander department, Colombia.

Fasciola hepatica is a parasite with a worldwide distribution that affects several mammals, including humans, and is considered a public health problem. Therefore, the aim of this study was to determine the prevalence of Fasciola hepatica in humans, cattle and sheep, as well as to evaluate factors associated with the prevalence. A total of 185 serum samples from sheep, 290 from cattle, and 114 from humans were collected and processed using an in-house developed ELISA to detect IgG antibodies against F. hepatica. Additionally, 185 stool samples from sheep and 290 from cattle were examined using a Dennis sedimentation technique. Risk factors were analyzed using epidemiological surveys. The overall seroprevalence was 46.5% (86/185) in sheep, 32.5% (94/289) in cattle, and no humans tested positive for the infection. The coprological prevalence was 47.7% (86/180) in sheep and 33.7% (98/290) in cattle. Female gender and cattle living with alternate grazing management showed 2.5 and 6.5 times higher probability of infection, respectively. Bovines coexisting with sheep exhibited a higher risk of infection (odds ratio [OR]=4.3) compared to those without sheep. We concluded that F. hepatica in cattle and sheep has an endemic behavior, and therefore represents a problem of public health for rural communities.

YouTube® as a source of information for Spanish-speaking patients with rheumatoid arthritis.

INTRODUCTION: Social media (SoMe) has reshaped access to health information, which may benefit patients with rheumatoid arthritis (RA), although an evaluation of the characteristics of contents for Spanish-speaking patients is lacking. We aimed to assess patient engagement, reliability, comprehensiveness, and quality of data uploaded to YouTube® for Spanish-speaking patients. METHODS: We evaluated the videos uploaded to YouTube® in Spanish about RA. Information about video length, engagement (i.e., views, likes, popularity index), time online, and the source was retrieved; we appraised reliability (DISCERN), comprehensiveness (content score), and quality (Global Quality Score) using standardized scores. RESULTS: We included 200 videos in the study and classified 67% of the videos as useful. These videos had a higher number of views (19,491 [10,132-61,162] vs. 11,208 [8183-20,538]), a longer time online (1156 [719-2254] vs. 832 [487-1708] days), and a shorter duration (6.3 [3.4-15.8] vs. 11.8 [7.4-20.3] min). Engagement parameters were similar between useful and misleading videos. Useful videos had higher reliability, comprehensiveness, and quality scores. Useful videos were mainly uploaded by independent users and government/news agencies; academic organizations offered only 15% of useful videos. CONCLUSIONS: Most of the information in YouTube® for Spanish-speaking patients with RA is useful; however, patient engagement is similar between useful and misleading content. More substantial involvement of academia in developing high-quality educational multimedia is warranted.

Development and psychometric evidence of the Academic Engagement Scale (USAES) in Mexican college students.

School engagement is considered an effective college dropout antidote; therefore, understanding the construct, its underpinnings, and its effects remains critical for scholars. Although several scholars have offered multiple scales to measure engagement, their use has been hindered by significant limitations. This study sought to develop a scale to measure academic engagement by unifying and improving existing work and theories that resulted in a three-dimensional measurement model (behavioral, emotional, and cognitive). The items included were validated by a group of experts who ensured that the wording of the items captured the uniqueness of the college experience. A sample of 992 Mexican college students was used to test the fit of a second-order three-dimensional factor model of school engagement. The sample was randomly split in two for model cross-validation. Confirmatory factor analyses confirmed that student engagement is a three-dimensional construct, with evidence that supports the hypothesized second-order engagement factor structure (behavioral, emotional, and cognitive). The stability of these models was confirmed by using an independent sample. Measurement invariance by gender was found in this model. Then, differences in latent factor means were analyzed. Finally, the scale showed discriminant and concurrent validity. These results indicate that the scale is theoretically and psychometrically grounded for measuring college students' school engagement.

Sin embargo, los parámetros de interacción son similares entre los videos útiles y los no útiles. Se requiere una mayor participación de las organizaciones académicas en el desarrollo de multimedia educativo de alta calidad.(AU)

Real-World Insights into Evolocumab Use in Patients with Hyperlipidemia Across Five Countries: Analysis from the ZERBINI Study.

INTRODUCTION: This study characterizes patients receiving evolocumab in clinical practice and assesses treatment effectiveness, safety and persistence outcomes across five countries. METHODS: This retrospective and prospective observational study enrolled patients initiated on evolocumab during August 2017 to July 2019 at 49 sites across Canada, Mexico, Colombia, Saudi Arabia and Kuwait. Medical records data were extracted within 6 months prior to (baseline) and every 3 months for 12 months post evolocumab initiation and reported as available. RESULTS: A total of 578 patients were enrolled (40.1% female, median age 60 [interquartile range (IQR) 51-68] years); 83.7% had atherosclerotic cardiovascular disease and/or familial hypercholesterolemia. Median low-density lipoprotein cholesterol (LDL-C) at baseline was 3.4 (IQR 2.7-4.2) mmol/L (131.5 [IQR 104.4-162.4] mg/dL), with 75.6% of patients receiving a statin (59.2% high intensity). Compared to baseline, the median lowest LDL-C was reduced by 70.2% and remained stable over 12 months of treatment. Guideline-recommended LDL-C thresholds < 1.8, < 1.4 and < 1.0 mmol/L (< 70, < 55 and < 40 mg/dL) were achieved by 75.3%, 63.6% and 47.4% of patients. LDL-C outcomes were consistent across high- and very high-risk patients. Background lipid-lowering therapy remained relatively stable. No serious treatment-emergent adverse events were reported, and persistence to evolocumab was 90.2% at 12 months. CONCLUSION: These findings provide real-world evidence that evolocumab use is in accordance with its international guideline-recommended place in dyslipidemia therapy, as well as confirmation of its effectiveness and safety in a heterogeneous population. Evolocumab can address a healthcare gap in the management of dyslipidemia by increasing the proportion of patients achieving LDL-C goals recommended to lower cardiovascular risk.

Implementing community based inclusive development for people with disability in Latin America: a mixed methods perspective on prioritized needs and lessons learned.

BACKGROUND: Research on the needs of people with disability is scarce, which promotes inadequate programs. Community Based Inclusive Development interventions aim to promote rights but demand a high level of community participation. This study aimed to identify prioritized needs as well as lessons learned for successful project implementation in different Latin American communities. METHODS: This study was based on a Community Based Inclusive Development project conducted from 2018 to 2021 led by a Columbian team in Columbia, Brazil and Bolivia. Within a sequential mixed methods design, we first retrospectively analyzed the project baseline data and then conducted Focus Group Discussions, together with ratings of community participation levels. Quantitative descriptive and between group analysis of the baseline survey were used to identify and compare sociodemographic characteristics and prioritized needs of participating communities. We conducted qualitative thematic analysis on Focus Group Discussions, using deductive main categories for triangulation: 1) prioritized needs and 2) lessons learned, with subcategories project impact, facilitators, barriers and community participation. Community participation was assessed via spidergrams. Key findings were compared with triangulation protocols. RESULTS: A total of 348 people with disability from 6 urban settings participated in the baseline survey, with a mean age of 37.6 years (SD 23.8). Out of these, 18 participated within the four Focus Group Discussions. Less than half of the survey participants were able to read and calculate (42.0%) and reported knowledge on health care routes (46.0%). Unemployment (87.9%) and inadequate housing (57.8%) were other prioritized needs across countries. Focus Group Discussions revealed needs within health, education, livelihood, social and empowerment domains. Participants highlighted positive project impact in work inclusion, self-esteem and ability for self-advocacy. Facilitators included individual leadership, community networks and previous reputation of participating organizations. Barriers against successful project implementation were inadequate contextualization, lack of resources and on-site support, mostly due to the COVID-19 pandemic. The overall level of community participation was high (mean score 4.0/5) with lower levels in Brazil (3.8/5) and Bolivia (3.2/5). CONCLUSION: People with disability still face significant needs. Community Based Inclusive Development can initiate positive changes, but adequate contextualization and on-site support should be assured.

Community Violence Exposure and Bullying in Mexican Adolescents. The Mediating Role of Moral Emotions.

Community characteristics can explain differences in bullying rates between schools. Underpinned by the social-ecological model, this study examined the relationships among community violence exposure (CVE), moral emotions (guilt and sympathy), and bullying in adolescents. We also explored the moderating role of gender in these relationships. The sample included 915 adolescents (48.6% female and 51.4% male) aged 11-16 (M age = 13.76, SD = 0.82). Students responded to the self-report measures. We used a latent variable structural equation modeling (SEM) approach to examine the relationships between variables. The SEM indicated that CVE was negatively associated with moral emotions (guilt and sympathy) and positively associated with bullying. In addition, CVE had a negative indirect association with bullying through their negative relationship with moral emotions. The structural model is equivalent for both genders, suggesting gender does not moderate these relationships. These findings indicate that CVE are associated with differences in school bullying rates.

However, the reasons for low compliance were different, highlighting the high number of administrative and medical reasons for suspension or abandonment of treatment with evolocumab.

Effectiveness evaluation of online Mindfulness in mental health and alcohol consumption in medical students during the COVID-19 pandemic / Evaluación de la eficacia del Mindfulness online en la salud mental y el consumo de alcohol en estudiantes de medicina durante la pandemia de COVID-19

Abstract Introduction As a result of the COVID-19 pandemic, the prevalence of stress, anxiety, depression, and alcohol consumption has increased among medical students. Mindfulness is an intervention to decrease these psychopathologies and alcohol consumption; however, evidence has shown unclear results regarding its efficacy. Objective To evaluate the effectiveness of an online Mindfulness-based intervention (MBI) on stress, anxiety, and depression symptomatology levels, as well as on alcohol consumption and mindfulness status in medical students during the COVID-19 pandemic. Method A quasi-experimental study was conducted on 237 students, obtaining sociodemographic data. In addition the levels of psychopathology, alcohol consumption, and state of mindfulness: were measured pre-and post-intervention through the DASS-21, AUDIT, and MASS instruments. Eight online Mindfulness sessions were conducted once a week for approximately one hour each. Results MBI did not reduce levels of psychopathologies or alcohol consumption, nor did the mindfulness status improve. High levels of psychopathologies, dropout rate, and lack of voluntary participation were the main factors limiting the effectiveness of the online MBI. Discussion and conclusion The online MBI wasn't effective among the population under study: we recommend generation strategies where students are involved in and complete intervention programs. Results from this research will help enhance future online mindfulness interventions.

Resumen Introducción Derivado de la pandemia del COVID-19, la prevalencia de estrés, ansiedad, depresión y consumo de alcohol ha incrementado entre los estudiantes de medicina. La intervención por Mindfulness ha reportado disminuir estas psicopatologías y el consumo de alcohol; no obstante, la evidencia muestra resultados poco claros respecto a su eficacia. Objetivo Evaluar la eficacia de la intervención basada en Mindfulness online (IBM) sobre los niveles de sintomatología de estrés, ansiedad y depresión, así como en el consumo de alcohol y el estado de atención plena en estudiantes de medicina durante la pandemia por COVID-19. Método Se realizó una investigación cuasi-experimental en 237 estudiantes de medicina, de los cuales se obtuvieron datos sociodemográficos; además, se midieron los niveles de psicopatologías, consumo de alcohol, y el estado de atención plena pre y post intervención a través de los instrumentos DASS-21, AUDIT, y MASS. Se llevaron a cabo ocho sesiones de Mindfulness online, una vez por semana, de aproximadamente una hora cada una. Resultados La IBM no redujo los niveles de psicopatologías ni de consumo de alcohol ni mejoró el estado de atención plena. Los altos niveles de psicopatologías, la tasa de abandono y la falta de participación voluntaria, fueron los principales factores que limitan la eficacia del IBM online. Discusión y conclusión La IBM online no fue efectiva entre la población estudiada: se recomienda la generación de estrategias en las que los estudiantes se involucren y completen los programas de intervención, los resultados de esta investigación ayudarán a mejorar futuras intervenciones de mindfulness online.

Prolongation of the QTc Interval at Admission is Associated with Increased Mortality in Patients with SARS-COV-2 during Hospitalization. / O Prolongamento do Intervalo QTc na Admissão está Associado ao Aumento da Mortalidade em Pacientes com SARS-COV-2 durante a Hospitalização.

BACKGROUND: Cardiovascular involvement associated with SARS-COV-2 infection is related to unfavorable outcomes during hospitalization. Therefore, the measurement at the admission of the QTc interval on the 12-lead electrocardiogram may be a prognostic marker. OBJECTIVE: To identify the relationship between QTc prolongation at admission during hospitalization and mortality from SARS-COV-2. METHOD: Observational study based on a retrospective cohort of patients with confirmed SARS-COV-2 infection from San Ignacio University Hospital, Bogotá (Colombia), between March 19, 2020, and July 31, 2021. Mortality was compared in patients with prolonged and normal QTc at admission after controlling by clinical variables and comorbidities using bivariate and multivariate logistic regression models. A p-value <0.05 was considered statistically significant. RESULTS: 1296 patients were analyzed, and 127 (9.8%) had prolonged QTc. Mortality was higher in patients with prolonged QTc (39.4% vs 25.3%, p=0.001), as was hospital stay (median 11vs.8 days; p=0.002). In the multivariate analysis, mortality was associated with prolonged QTc (OR 1.61, 95% CI: 1.02; 2.54, p=0.038), age (OR 1.03, 95% CI 1.02; 1.05, p<0.001), male sex (OR 2.15, 95% CI 1.60; 2.90, p <0.001), kidney disease (OR 1.32, 95% CI 1.05; 1.66, p =0.018) and Charlson comorbidity index > 3 (OR 1.49, 95% CI 1.03; 2.17, p=0.035). CONCLUSIONS: Hospital mortality due to SARS-COV-2 is associated with prolonging the QTc interval at the time of admission, even after adjusting for age, sex, comorbidities, and basal severity of infection. Additional research is needed to establish whether these findings are related to cardiac involvement by the virus, hypoxia, and systemic inflammation.

FUNDAMENTO: O envolvimento cardiovascular associado à infecção por SARS-COV-2 está relacionado a desfechos desfavoráveis durante a internação. Portanto, a medida na admissão do intervalo QTc no eletrocardiograma de 12 derivações pode ser um marcador prognóstico. OBJETIVO: Identificar a relação entre o prolongamento do QTc na admissão durante a hospitalização e a mortalidade por SARS-COV-2. MÉTODO: Estudo observacional baseado em uma coorte retrospectiva de pacientes com infecção confirmada por SARS-COV-2 do Hospital Universitário San Ignacio, Bogotá (Colômbia), entre 19 de março de 2020 e 31 de julho de 2021. A mortalidade foi comparada em pacientes com QTc prolongado e normal na admissão e controle das variáveis clínicas e comorbidades por meio de modelos de regressão logística bivariada e multivariada. Um valor de p <0,05 foi considerado estatisticamente significativo. RESULTADOS: Foram analisados 1.296 pacientes e 127 (9,8%) apresentaram QTc prolongado. A mortalidade foi maior em pacientes com QTc prolongado (39,4% vs. 25,3%, p=0,001), assim como o tempo de internação (mediana 11 vs. 8 dias; p=0,002). Na análise multivariada, a mortalidade foi associada a QTc prolongado (OR 1,61, IC 95%: 1,02; 2,54, p=0,038), idade (OR 1,03, IC 95% 1,02; 1,05, p<0,001), sexo masculino (OR 2,15, IC 95% 1,60; 2,90, p<0,001), doença renal (OR 1,32, IC 95% 1,05; 1,66, p=0,018) e índice de comorbidade de Charlson > 3 (OR 1,49, IC 95% 1,03; 2,17, p=0,035). CONCLUSÕES: A mortalidade hospitalar por SARS-COV-2 está associada ao prolongamento do intervalo QTc no momento da admissão, mesmo após ajuste para idade, sexo, comorbidades e gravidade basal da infecção. Pesquisas adicionais são necessárias para estabelecer se esses achados estão relacionados ao envolvimento cardíaco pelo vírus, hipóxia e inflamação sistêmica.

O Prolongamento do Intervalo QTc na Admissão está Associado ao Aumento da Mortalidade em Pacientes com SARS-COV-2 durante a Hospitalização / Prolongation of the QTc Interval at Admission is Associated with Increased Mortality in Patients with SARS-COV-2 during Hospitalization

Resumo Fundamento O envolvimento cardiovascular associado à infecção por SARS-COV-2 está relacionado a desfechos desfavoráveis durante a internação. Portanto, a medida na admissão do intervalo QTc no eletrocardiograma de 12 derivações pode ser um marcador prognóstico. Objetivo Identificar a relação entre o prolongamento do QTc na admissão durante a hospitalização e a mortalidade por SARS-COV-2. Método Estudo observacional baseado em uma coorte retrospectiva de pacientes com infecção confirmada por SARS-COV-2 do Hospital Universitário San Ignacio, Bogotá (Colômbia), entre 19 de março de 2020 e 31 de julho de 2021. A mortalidade foi comparada em pacientes com QTc prolongado e normal na admissão e controle das variáveis clínicas e comorbidades por meio de modelos de regressão logística bivariada e multivariada. Um valor de p <0,05 foi considerado estatisticamente significativo Resultados Foram analisados 1.296 pacientes e 127 (9,8%) apresentaram QTc prolongado.

Abstract Background Cardiovascular involvement associated with SARS-COV-2 infection is related to unfavorable outcomes during hospitalization. Therefore, the measurement at the admission of the QTc interval on the 12-lead electrocardiogram may be a prognostic marker. Objective To identify the relationship between QTc prolongation at admission during hospitalization and mortality from SARS-COV-2. Method Observational study based on a retrospective cohort of patients with confirmed SARS-COV-2 infection from San Ignacio University Hospital, Bogotá (Colombia), between March 19, 2020, and July 31, 2021. Mortality was compared in patients with prolonged and normal QTc at admission after controlling by clinical variables and comorbidities using bivariate and multivariate logistic regression models. A p-value <0.05 was considered statistically significant. Results 1296 patients were analyzed, and 127 (9.8%) had prolonged QTc. Mortality was higher in patients with prolonged QTc (39.4% vs 25.3%, p=0.001), as was hospital stay (median 11vs.8 days; p=0.002). In the multivariate analysis, mortality was associated with prolonged QTc (OR 1.61, 95% CI: 1.02; 2.54, p=0.038), age (OR 1.03, 95% CI 1.02; 1.05, p<0.001), male sex (OR 2.15, 95% CI 1.60; 2.90, p <0.001), kidney disease (OR 1.32, 95% CI 1.05; 1.66, p =0.018) and Charlson comorbidity index > 3 (OR 1.49, 95% CI 1.03; 2.17, p=0.035). Conclusions Hospital mortality due to SARS-COV-2 is associated with prolonging the QTc interval at the time of admission, even after adjusting for age, sex, comorbidities, and basal severity of infection. Additional research is needed to establish whether these findings are related to cardiac involvement by the virus, hypoxia, and systemic inflammation.

Randomized double-blind clinical study in patients with COVID-19 to evaluate the safety and efficacy of a phytomedicine (P2Et).

Background: It has been proposed that polyphenols can be used in the development of new therapies against COVID-19, given their ability to interfere with the adsorption and entrance processes of the virus, thus disrupting viral replication. Seeds from Caesalpinia spinosa, have been traditionally used for the treatment of inflammatory pathologies and respiratory diseases. Our team has obtained an extract called P2Et, rich in polyphenols derived from gallic acid with significant antioxidant activity, and the ability to induce complete autophagy in tumor cells and reduce the systemic inflammatory response in animal models. Methods: In this work, a phase II multicenter randomized double-blind clinical trial on COVID-19 patients was designed to evaluate the impact of the P2Et treatment on the clinical outcome and the immunological parameters related to the evolution of the disease. The Trial was registered with the number No. NCT04410510*. A complementary study in an animal model of lung fibrosis was carried out to evaluate in situ lung changes after P2Et in vivo administration. The ability of P2Et to inhibit the viral load of murine and human coronaviruses in cellular models was also evaluated. Results: Patients treated with P2Et were discharged on average after 7.4 days of admission vs. 9.6 days in the placebo group. Although a decrease in proinflammatory cytokines such as G-CSF, IL-15, IL-12, IL-6, IP10, MCP-1, MCP-2 and IL-18 was observed in both groups, P2Et decreased to a greater extent G-CSF, IL-6 and IL-18 among others, which are related to lower recovery of patients in the long term. The frequency of T lymphocytes (LT) CD3+, LT double negative (CD3+CD4-CD8-), NK cells increased in the P2Et group where the population of eosinophils was also significantly reduced. In the murine bleomycin model, P2Et also reduced lung inflammation and fibrosis. P2Et was able to reduce the viral replication of murine and human coronaviruses in vitro, showing its dual antiviral and anti-inflammatory role, key in disease control. Conclusions: Taken together these results suggest that P2Et could be consider as a good co-adjuvant in the treatment of COVID-19.

Cambio en la mortalidad intrahospitalaria durante el primer pico por SARS- COV-2 en Bogotá, Colombia / Change of in-hospital mortality during the first SARS-COV-2 surge in Bogotá, Colombia

Resumen Introducción: La mortalidad por SARS-COV-2 ha disminuido en diferentes países, pero no se ha evaluado si es igual en Colombia, o si se relaciona con las carac terísticas de los pacientes y tratamientos utilizados. Objetivo: Comparar la mortalidad por SARS-COV-2, en dos periodos de tiempo controlando por factores de riesgo asociados con mortalidad. Metodología: Estudio observacional, basado en una cohorte retrospectiva de pacientes con SARS-COV-2 atendidos en el Hospital Universitario San Ignacio, Bogotá (Colombia), desde el 19 de marzo al 12 de noviembre, 2020. Se comparó la tasa de mortalidad intrahospitalaria de los pacientes egresados antes y después del 21 de agosto de 2020 (primer pico de mortalidad en Colombia) y se analizó el impacto del momento de atención controlando por comorbilidades, severidad al ingreso y tratamiento recibido, usando un modelo de regresión logística. Resultados: 1399 pacientes (944 antes y 455 después del primer pico de mortalidad) fueron analizados. La tasa de mortalidad intrahospitalaria global fue similar en ambos periodos (17.6% vs 16.3%, p=0.539). En el análisis multivariado se encontró que la atención en el segundo periodo de tiempo se asoció a menor mortalidad (OR 0.66 IC95% 0.47; 0.93, p=0.018), a diferencia del aumento de la misma asociado a la edad (OR 1.06 IC95% 1.05; 1.07, p<0.001), sexo masculino (OR 1.84 IC95% 1.33; 2.54 p<0.001), cirrosis (OR 1.89 IC95% 1.24; 2.88, p=0.003), enfermedad renal (OR 1.36 IC95% 1.00; 1.83, p=0.043) y el uso de dexametasona (OR 1.53 IC95% 1.03; 2.28, p=0.031). Conclusiones: La tasa de mortalidad intrahospitalaria se redujo después del 21 de agosto durante la primera ola de la pandemia en Bogotá, posiblemente asociado a la mejoría en la capacidad de respuesta del sistema de salud en ese momento, o a un menor inoculo viral de los pacientes infectados. Estos hallazgos pueden cambiar con la saturación del sistema de salud.

Abstract Introduction: Mortality secondary to SARS-COV 2 has decreases around the world, however this has not been evaluated in Colombia neither has the correlation between patient characteristics or treatments. Objective: To compare the mortality due to SARS-COV-2, in two periods of time, controlling risk factors associated with mortality. Methodology: Observational retrospective cohort study of patients with SARS- COV-2 treated at the San Ignacio University Hospital in Bogotá (Colombia), from March 19 to November 12, 2020. The in-hospital mortality rate of patients discharged before and after August 21, 2020 (surge mortality in Colombia) was com pared. The impact of the moment of attention was analyzed controlled by comorbidities, severity at admission and treatment received using a bivariate and multivariate logistic regression model. Results: 1399 patients (944 before and 455 after August 21) were analyzed. The overall in-hospital mortality rate was similar at both times (17.6%vs16.3percentage, p=0.539). In the multivariate analysis, it was found that the moment of attention was associated with lower mortality (OR 0.66 95% CI0.47;0.93,p=0.018), in contrast to its increase associated with age (OR 1.06 95% CI 1.05;1.07,p=<0.001), male sex (OR 1.84 95%CI 1.33;2.54,p=<0.001), cirrhosis (OR1.89 95%CI 1.24;2.88, p=0.003), kidney disease (OR 1.36 95% CI1.00;1.83,p=0.043) and the use of dexamethasone (OR1.53 95%CI 1.03;2.28,p=0.031). Conclusions: The in-hospital mortality rate fell after August 21 during the first wave of the pandemic in Bogotá-Colombia, possibly associated with an improvement in response capacity, or a lower viral inoculum of infected patients. These findings may change with the saturation of the health system

Psychometric Properties of the Multidimensional Temperance Scale in Adolescents.

Recent research has shown the relevance of measuring the virtue of temperance. The present study tested a multidimensional and second-order structure scale to assess temperance using a sub-scale of the Values in Action Inventory of Strengths for Youth (VIA-Youth). Scale properties were tested using data from a sample of 860 adolescents aged from 12 to 18 years old (M = 14.28 years, SD = 1.65). The sample was randomly split into two subsamples for model cross-validation. Using the first sample, we assessed scale dimensionality, measurement invariance, and discriminant and concurrent validity. A second sample was used for model cross-validation. Confirmatory factorial analysis confirmed the fit of one second-order factor temperance virtue model, with the dimensions of forgiveness, modesty, prudence, and self-control. The results indicate scale measurement equivalence across gender and stage of adolescence (early vs. middle). Latent means difference tests showed significant differences in forgiveness, modesty, and self-regulation by gender, and modesty according to adolescence stage. Moreover, the scale showed discriminant and concurrent validity. These findings indicate that this scale is helpful for assessing temperance in adolescents and suggest the value of temperance as a multidimensional and second-order construct.
