Retinal vein occlusion in the general population after COVID-19 vaccination and infection.

INTRODUCTION: Retinal vein occlusion (RVO) is mostly a consequence of vascular risk factors (VRF). COVID-19 vaccines have been related to vascular and thrombotic events (VTE). OBJECTIVE: To assess the RVO incidence in the general population in our health area and the possible relation with COVID-19 infection and vaccination. METHODS: Demographic features, classic VRF, thrombophilia data, COVID-19 status, and Framingham risk score were collected prospectively. RESULTS: 472 consecutive patients studied over 13 years with RVO were included (Valdecilla Cohort). Classic VRFs were present in 90%, antiphospholipid syndrome in 12.3%, and genetic thrombophilia in 13.5%. Ninety-one percent of RVO patients were vaccinated and 6.8% suffered COVID-19 infection. In the cohort, no patient had a new RVO after vaccination or infection. In the general population, 20 subjects had RVO after receiving the vaccine (0.006%). Overall, 8 cases occurred in the first-month post-vaccination and 12 after 30 days. In the early and late groups, there are 3 and 4 patients respectively, with a low-intermediate risk Framingham score. Twenty-nine patients in the cohort suffered SARS-CoV-2 infection, twenty-seven of them had RVO before infection. Two patients with low-risk Framingham scores had RVO after infection, one of them early (<1 month). CONCLUSIONS: Vaccination and COVID-19 might be involved in the development of RVO in some cases, mainly in patients without VRF, thrombophilia, or chronic inflammatory conditions and with a lower Framingham score, especially in the first month after vaccination or infection.

'Feeling disconnected' - risk factors for PGD and themes in grief counselling during the COVID-19 pandemic. A mixed-method study.

Background: Due to its high death toll and measures to curb the pandemic, COVID-19 has affected grieving experiences and may contribute to risk factors for Prolonged Grief Disorder (PGD). Persons at risk for PGD often seek support from grief counselling.Objective: To explore whether pandemic-associated risk factors have become more important topics in counselling in a mixed-method design.Method: German grief counsellors (n = 93) rated whether pre-defined risk factors had become more important in grief counselling and indicated additional important themes in an open format.Results: The counsellors indicated that all pre-defined risk factors had become more important, though differing significantly in their frequency. Most frequently endorsed risk factors were lack of social support, limited possibilities to accompany a dying loved one and absence of traditional grief rituals. Qualitative analysis identified three additional themes: the societal impact of the pandemic, its impact on bereavement support and health care, and a chance for personal growth.Conclusions: The pandemic has affected bereavement experiences and grief counselling. Counsellors should monitor grief processes and specific risk factors to provide the best possible care for bereaved people when needed.

Pandemic-associated risk factors for PGD have become more important topics in grief counselling during COVID-19.Risk factors include especially a lack of social support, limited possibility to accompany a dying significant other and absence of traditional grief rituals.Future research is needed to investigate whether monitoring and addressing these risk factors can improve bereavement care.

Prevalence of thrombosis in patients with cancer and SARS-CoV-2 infection.

BACKGROUND: Covid-19 infection and cancer are associated with an increased risk of thrombotic events. The aim of our study is to analyze the cumulative incidence of thrombosis in oncological patients with Covid-19 and detect differences with the non-cancer Covid-19 population. METHODS: We retrospectively reviewed 1127 medical records of all admitted patients to ward of the Hospital Universitario Infanta Leonor (Madrid, Spain), including 86 patients with active cancer between March 5th, 2020 to May 3rd, 2020. We analyzed cumulative incidence of thrombosis and risk factors associated to the cancer patient's cohort. RESULTS: We diagnosed 10 thrombotic events in 8 oncological patients with a cumulative incidence of 9.3%. A statistically significant association was found regarding thrombosis and history of obesity (p=0.009). No differences related to cumulative incidence of thrombosis between both groups were detected (9.8% vs 5.80%) in our hospital (p=0.25). CONCLUSION: No significant differences were observed in the cumulative incidence of thrombosis in the two study groups. The thrombotic effect of Covid-19 is not as evident in cancer patients and does not seem to be added to its prothrombotic activity.

Mortality Related to SARS-CoV-2 in Patients with Kidney Transplant from a Center in Northeastern Colombia / Mortalidad secundaria a SARS-CoV-2 en pacientes con trasplante renal de un centro del nordeste colombiano

Objetivo Describir la tasa de mortalidad de infección por coronavirus de tipo 2 causante del síndrome respiratorio agudo severo (severe acute respiratory syndrome coronavirus 2, SARS-CoV-2, en inglés) y los factores de riesgo asociados a la severidad de la enfermedad en pacientes con trasplante renal de un centro del nordeste colombiano. Materiales y Métodos Estudio descriptivo de una cohorte de pacientes en seguimiento postrasplante renal, en el que se hizo una búsqueda retrospectiva de los que presentaron infección por SARS-CoV-2 entre marzo del 2020 y mayo del 2021. Para el análisis, se incluyeron los pacientes con infección confirmada mediante pruebas de reacción en cadena de la polimerasa (polymerase chain reaction, PCR, en inglés), de antígenos, o de anticuerpos. Se realizó un análisis descriptivo de las variables sociodemográficas y clínicas, y un análisis bivariado de los posibles factores asociados con el riesgo de mortalidad. Resultados Con un total de 307 individuos en seguimiento, se encontró una prevalencia del 14,3% (n = 44) de infección por enfermedad por coronavirus 2019 (coronavirus disease 2019, COVID-19, en inglés). La media de edad fue de 56 años, con predominio del género masculino. El esquema de inmunosupresión más frecuente fue micofenolato­tacrolimus­prednisona. Entre los pacientes infectados, la mortalidad fue del 34,1% (15/44), lo que representa el 4,8% de toda la población a estudio. Maás de la mitad de los pacientes requirieron hemodiálisis, y en el 86,7% fue necesario hacer ajustes en el esquema de inmunosupresión. Conclusión La prevalencia de infección por SARS-CoV-2 en nuestro grupo de trasplantes fue similar a la reportada por otros grupos de trasplante del país, y mayor a la de la población no trasplantada. El valor de creatinina previo a la infección, la edad y las comorbilidades se asociaron con un mayor riesgo de mortalidad.

Objective To describe the mortality related to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and the risk factors associated with disease severity in patients submitted to a kidney transplant from a center in northeastern Colombia. Materials and Methods The present is a descriptive study of a cohort of patients in follow-up care after kidney transplant, with a retrospective search for those who presented SARS-CoV-2 infection between March 2020 and May 2021. Patients with confirmed infection by polymerase chain reaction (PCR), antigens or antibodies tests were included for analysis. We performed a descriptive analysis of the sociodemographic and clinical variables as well as a bivariate analysis to evaluate the possible factors associated with the risk of mortality. Results With a total of 307 individuals in follow-up care, a prevalence of 14.3% (n = 44) of coronavirus disease 2019 (COVID-19) infection was found. The mean age of the sample was of 56 years, with a male predominance. The most frequent immunosuppression regimen was mycophenolate-tacrolimus-prednisone. Among the infected patients, the mortality rate was of 34.1% (15/44), representing 4.8% of the entire study population. More than half of the patients required hemodialysis, and 86.7% required adjustments to the immunosuppression regimen. Conclusion The prevalence of SARS-CoV-2 infection in our transplant group was similar to that reported by other transplant groups in the country and higher than among the non-transplanted population. The preinfection creatinine value, age, and comorbidities were associated with a higher risk of mortality.

Quality of systematic reviews of COVID-19 in people with diabetes: A systematic review.

OBJECTIVE: To investigate the methodological quality of published systematic reviews of factors associated with COVID-19 in people with diabetes. METHOD: Systematic review with registration protocol in PROSPERO, under the number CRD42020222418. Searches were carried out from October to November 2020 in the databases of the MedLine, Web of Science, Scopus, Lilacs, Embase and Cochrane libraries, in addition to searching the reference list of the selected studies. Systematic review studies with or without meta-analysis and without date and language restrictions were included. Data were extracted in a standardized way and the quality of the studies was assessed using the Assessment of Multiple Systematic Reviews scale. RESULTS: Twelve reviews, published between 2020 and 2021, with a predominance of the English language, systematic reviews of observational studies with meta-analysis with a sample ranging from six to 83 studies, were included. Regarding financing, most of the study reported did not receive this type of support. Regarding to the assessment of the methodological quality of the studies, three were of moderate quality, five were classified as low quality and three with critically low quality. CONCLUSIONS: The analyzed articles presented a bias in the preparation of reports on their studies, suggesting the need to use mechanisms to improve adherence to the established reporting guidelines and methodological evaluation tools.

Factors associated with mortality due to SARS-CoV-2 in the population over 75 years of age in the Community of Madrid.

OBJECTIVE: Various studies have identified factors associated with risk of mortality in patients with SARS-CoV-2 infection. However, their sample size has often been limited and their results partially contradictory. This study evaluated factors associated with COVID-19 mortality in the population of Madrid over 75 years of age, in infected patients, and in hospitalized patients up to January 2021. PATIENTS AND METHODS: This population-based cohort study analyzed all residents of the Community of Madrid born before January 1, 1945 who were alive as of December 31, 2019. Demographic and clinical data were obtained from primary care electronic medical records (PC-Madrid), data on hospital admissions from the Conjunto Mínimo Básico de Datos (CMBD, Minimum Data Set), and data on mortality from the Índice Nacional de Defunciones (INDEF, National Death Index). Data on SARS-CoV-2 infection, hospitalization, and death were collected from March 1, 2020 to January 31, 2021. RESULTS: A total of 587,603 subjects were included in the cohort. Of them, 41,603 (7.1%) had confirmed SARS-CoV-2 infection, of which 22,362 (53.7% of the infected individuals) were hospitalized and 11,251 (27%) died. Male sex and age were the factors most closely associated with mortality, though many comorbidities also had an influence. The associations were stronger in the analysis of the total population than in the analysis of infected or hospitalized patients. Mortality among hospitalized patients was lower during the second wave (33.4%) than during the first wave (41.2%) of the pandemic. CONCLUSION: Age, sex, and numerous comorbidities are associated with risk of death due to COVID-19. Mortality in hospitalized patients declined notably after the first wave of the pandemic.

Risk factors and spatial distribution associated with deaths due to COVID-19: an integrative review / Fatores de risco e distribuição espacial associados aos óbitos por COVID-19: uma revisão integrative / Factores de riesgo y distribución espacial asociados a las muertes por COVID-19: una revisión integradora

Background and objectives: understanding the clinical-epidemiological and environmental factors related to deaths due to COVID-19 and their distribution in space can serve as subsidies to direct and implement more effective health actions for vulnerable populations. Thus, the objective was to synthesize the scientific evidence related to risk factors and spatial distribution of deaths due to COVID-19 in the world. Content: this is an integrative literature review, and the following guiding question emerged: what is the scientific evidence related to risk factors and spatial distribution of deaths due to COVID-19 in the world? Searches were carried out in the Scientific Electronic Library Online (SciELO) and the Scopus, Web of Science and National Library of Medicine (PubMed) databases in June 2021. Original studies in Portuguese, English or Spanish, without time frame, excluding studies with a specific age group or with an audience with specific comorbidity, were used. A total of 25 studies were included, with findings in different scenarios around the world. Factors such as age, sex, pre-existing diseases were associated with deaths due to COVID-19, which had a heterogeneous spatial distribution and occurred in environmental, socioeconomic and geographic conditions peculiar to these territories. Conclusion: age equal to or greater than 60 years, males, cardiovascular diseases, diabetes mellitus and geographic areas with greater environmental pollution, greater population density and precarious sanitary conditions influenced the mortality of COVID-19.(AU)

Incidencia De Eventos Tromboembólicos Venosos En Pacientes Hospitalizados Con COVID-19

Resumen Antecedentes y objetivo: Diversos estudios han reportado alteraciones tromboembólicas en los pacientes con neumonía por SARS-CoV-2, sin embargo, no se cuentan con datos definitivos acerca de los factores de riesgo para la aparición de dichos eventos. El objetivo de este estudio fue analizar la relación existente entre los factores personales, clínicos y paraclínicos con el desarrollo de complicaciones tromboembólicas venosas en pacientes hospitalizados con COVID-19. Métodos: Estudio de seguimiento a una cohorte retrospectiva de pacientes COVID-19 ingresados, de agosto del 2020 a febrero de 2021, en la Clínica Antioquia de Itagüí. Se incluyeron 525 historias clínicas de pacientes mayores de 18 años con diagnóstico confirmado para SARS-CoV-2. Resultados: Se identificó la presencia de eventos tromboembólicos en el 3% de los pacientes hospitalizados. De los pacientes con COVID-19 el 25,1% ingresó a unidad de cuidados intensivos, el 18,9% requirió ventilación mecánica invasiva. La mortalidad por COVID-19 en nuestro estudio fue de 18,1%. En los sujetos hospitalizados con SARS-CoV-2 se identificó asociación entre el desarrollo de eventos tromboembólicos con los niveles elevados de troponina I (HR 4,07;IC 95% 1,09-15,18), el antecedente de eventos tromboembólicos (HR 11,01;IC 95% 1,06-114,87) y trombocitopenia (HR 6,47;IC 95% 2,05-20,44). Conclusiones: Se encontró asociación entre las complicaciones tromboembólicas y el antecedente de ETV. Igualmente se concluyó que los valores de troponina ≧0,03 ngr/ml y niveles de plaquetas <150.000/mm3 se asocian con ETV. Background and objective: Several studies have reported on the thromboembolic alterations developed in patients with SARS-CoV-2 pneumonia, however, there are no definitive data on the risk factors for the appearance of these events. The aim of this study was to analyse the relationship between personal, clinical, and paraclinical factors and the development of venous thromboembolic complications in hospitalized patients with COVID-19. Methods: Follow-up study of a retrospective cohort of COVID-19 patients admitted, from August 2020 to February 2021, to the Clínica Antioquia de Itagüí. 525 medical records of patients older than 18 years with a confirmed diagnosis of SARS-CoV-2 were included. Results: The presence of VTE was identified in 3% of hospitalized patients. Of the patients with COVID-19, 25.1% were admitted to the intensive care unit, 18.9% required invasive mechanical ventilation. Mortality from COVID-19 in our study was 18.1%. In patients hospitalized with SARS-CoV-2, an increased risk of development of thromboembolic events was identified in those with elevated levels of troponin I (HR 4.07;95% CI 1.09-15.18), a history of prior thromboembolic events (HR 11.01;95% CI 1.06-114.87), and thrombocytopenia (HR 6.47;95% CI 2.05-20.44). Conclusions: An association was found between thromboembolic complications and a history of VTE. Likewise, it was concluded that troponin values ​​≧ .03 ng/ml and platelet levels <150,000 / mm3 are associated with VTE.

Clinical characteristics and mortality risk factors in patients aged less than 18 years with COVID-19 in Mexico and Mexico City.

INTRODUCTION: In the paediatric population, coronavirus disease (COVID-19) is usually asymptomatic or mild, but there are also severe and fatal cases. METHODS: We analysed data on COVID-19 cases from the national and state-level databases of the Federal Ministry of Health of Mexico and the Department of Health of Mexico City to determine the clinical characteristics and risk factors for mortality in children. We used Cox proportional hazards regression analysis to calculate the risk of death. RESULTS: The national and Mexico City databases had recorded a total of 18,465 (2.8%) and 5,733 (4.2%) confirmed cases of COVID-19, respectively, in individuals aged less than 18 years as of September 2020. The median age at diagnosis was 12 years (range: 0-17). The differences between cases in the national vs Mexico City databases were: 12.5% vs 8.2% of patients were hospitalised; 6% vs 3.5% had pneumonia; 2.4% vs 1.9% were admitted to the intensive care unit (ICU), and 1.3% vs 0.7% died. The independent risk factors significantly associated with a higher probability of death were pneumonia, hypertension, obesity, immunosuppression and intubation. CONCLUSION: In Mexico, 2.8% of all confirmed cases of COVID-19 occurred in individuals under 18 years, with a median age of 12 years and a mortality of 1.3%. The identified predictors of mortality were pneumonia, admission to the ICU, obesity, hypertension, immunosuppression, diabetes, chronic lung disease and renal disease.

El 38,7% (n = 12) de profesionales atiende más de 15 pacientes por turno. Frente a la presencia de burnout, el 38,7% (n = 12) presentan agotamiento laboral, ya sea por cansancio emocional, despersonalización o baja realización personal. Finalmente, un 64,5% (n = 20) y un 74,2% (n = 23) considera que su salud mental o física se ha deteriorado por las condiciones laborales dada la actual pandemia por SARS-CoV-2, respectivamente. Conclusiones Un porcentaje considerable de profesionales presenta agotamiento laboral. Se resaltan algunas condiciones psicosociales y laborales (insuficiente personal, jornada agotadora, falta colaboración, pérdida de información) asociadas a la presencia de burnout. Existe deterioro de la salud física y mental de los profesionales por la pandemia SARS-CoV-2. Objective To evaluate the association of psychosocial and work factors in the presence of job exhaustion in physiotherapists and respiratory therapists of a highly complex hospital in Bogotá, Colombia. Materials and methods An analytical cross-sectional study. 31 physiotherapists and respiratory therapists from a high complexity hospital were surveyed. The data collection was carried out through a virtual questionnaire, it included psychosocial, demographic and labor variables;the prevalence of burnout was assessed using the Maslach Burnout Inventory for health professionals. Univariate and bivariate analyses were performed using SPSS version 25.0. Results It was found that 93.5% (n = 29) corresponded to female, the mean age was 36±8.7 years old, with a type of fixed-term employment relationship of 96.8% (n = 30). Number of patients seen per shift of more than 15 patients in 38.7% (n = 12) of the cases. The 38.7% (n = 12) of the professionals presented job exhaustion, either due to emotional exhaustion, depersonalization, or low personal fulfillment. Finally, 64.5% (n = 20) and 74.2% (n = 23) considered that their mental or physical health has deteriorated due to working conditions given the current SARS-CoV-2 pandemic. Conclusion A considerable percentage of professionals presented job exhaustion. Some psychosocial and working conditions are highlighted (insufficient staff, exhausting workday, lack of collaboration, loss of information) associated with the presence of burnout. There is deterioration in the physical and mental health of professionals due to the SARS-CoV-2 pandemic.

[Risk factors for mortality in patients over 65 years old hospitalized by COVID-19]. / Factores de riesgo de mortalidad en pacientes mayores de 65 años hospitalizados por COVID-19.

BACKGROUND AND OBJECTIVE: COVID-19 is a disease caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and has caused a global pandemic that we are currently suffering from. OBJECTIVE: to identify factors associated with the death of patients aged 65 years or older hospitalized for COVID-19. MATERIALS AND METHODS: Retrospective cohort study. We included patients aged 65 years or older who were hospitalized for COVID-19 and dead o discharged between March 5 and 25, 2020. We used univariable and multivariable logistic regression methods to explore the risk factors associated with in-hospital death. RESULTS: 277 patients were included in this study. The bivariate analysis showed significant differences (p<0.05) between survivors and non survivors: age, increased dependence and comorbidity, history of ischemic heart disease, renal failure and non-hematological neoplasms, heart failure during admission, leukocytosis, elevated creatinine, PCR, GOT and troponin Ic values, lymphopenia, and decreased blood pH and SatO2. Multivariate logistic regression revealed that age ≥65 years (OR: 4.23 (95% CI: 1.43-12.52; p=0.009), lymphopenia <1000/µL (OR: 2.36 (95% CI: 1.07-5.20; p=0.033), creatinine>1.2mg/dL (OR: 3.08 (95% CI: 1.37-6.92; p=0.006), SatO2 <90% (OR: 2.29 (95% CI: 1.01-5.21; p=0.049) and troponin Ic>11ng/mL (OR: 2.32 (95% CI: 1.04-5.16; p=0.040) were independently associated with higher hospital mortality. CONCLUSIONS: Older age, lymphopenia, SatO2 <90%, elevated creatinine and troponin Ic values were independently associated with higher mortality in hospitalized patients with COVID-19, these factors could help clinicians to identify patients with poor prognosis.

Effects of the COVID-19 pandemic on a cohort of patients with vein occlusion.

BACKGROUND AND OBJECTIVES: A new coronavirus disease in humans, COVID-19, caused by SARS-CoV-2, emerged in December 2019. It has been associated with the development of thrombotic phenomena. Retinal vein occlusion (RVO) is mainly a consequence of vascular risk factors (VRF). This study aimed to analyze cases of COVID-19 in a cohort of patients with RVO (Valdecilla cohort). PATIENTS AND METHODS: Between December 2008 and December 2020, 429 patients with RVO were attended to in our clinic. Ten patients had COVID-19, one of which did not have VRF or thrombophilia. The remaining nine patients had RVO prior to the infection and VRF, six had carotid atherosclerosis, and four had antiphospholipid syndrome. The infection did not cause thrombotic phenomena in any of them. CONCLUSIONS: RVO is a rare manifestation of COVID-19. In our cohort of patients with RVO, COVID-19 disease did not lead to thrombotic events.

COVID-19 Unmasked Global Collaboration Protocol: longitudinal cohort study examining mental health of young children and caregivers during the pandemic.

BACKGROUND: Early empirical data shows that school-aged children, adolescents and adults are experiencing elevated levels of anxiety and depression during the COVID-19 pandemic. Currently, there is very little research on mental health outcomes for young children. OBJECTIVES: To describe the formation of a global collaboration entitled, 'COVID-19 Unmasked'. The collaborating researchers aim to (1) describe and compare the COVID-19 related experiences within and across countries; (2) examine mental health outcomes for young children (1 to 5 years) and caregivers over a 12-month period during the COVID-19 pandemic; (3) explore the trajectories/time course of psychological outcomes of the children and parents over this period and (4) identify the risk and protective factors for different mental health trajectories. Data will be combined from all participating countries into one large open access cross-cultural dataset to facilitate further international collaborations and joint publications. METHODS: COVID-19 Unmasked is an online prospective longitudinal cohort study. An international steering committee was formed with the aim of starting a global collaboration. Currently, partnerships have been formed with 9 countries (Australia, Cyprus, Greece, the Netherlands, Poland, Spain, Turkey, the UK, and the United States of America). Research partners have started to start data collection with caregivers of young children aged 1-5 years old at baseline, 3-months, 6-months, and 12-months. Caregivers are invited to complete an online survey about COVID-19 related exposure and experiences, child's wellbeing, their own mental health, and parenting. DATA ANALYSIS: Primary study outcomes will be child mental health as assessed by scales from the Patient-Reported Outcomes Measurement Information System - Early Childhood (PROMIS-EC) and caregiver mental health as assessed by the Depression Anxiety Stress Scale (DASS-21). The trajectories/time course of mental health difficulties and the impact of risk and protective factors will be analysed using hierarchical linear models, accounting for nested effects (e.g. country) and repeated measures.

Antecedentes: Los primeros datos empíricos muestran que los niños en edad escolar, los adolescentes y los adultos están experimentando niveles elevados de ansiedad y depresión durante la pandemia de COVID-19. Actualmente, hay muy poca investigación sobre los resultados de salud mental de los niños pequeños. Objetivos: Describir la formación de una colaboración global titulada 'COVID-19 Desenmascarado'. Los investigadores colaboradores tienen como objetivos (1) describir y comparar las experiencias relacionadas con COVID-19 dentro y entre países; (2) examinar los resultados de salud mental de los niños pequeños (de 1 a 5 años) y los cuidadores durante un período de 12 meses durante la pandemia de COVID-19; (3) explorar las trayectorias/temporalidad de los resultados psicológicos de los niños y los padres durante este período e (4) identificar los factores de riesgo y de protección para las diferentes trayectorias de salud mental. Los datos de todos los países participantes se combinarán en un gran conjunto de datos transculturales de acceso abierto para facilitar más colaboraciones internacionales y publicaciones conjuntas. Métodos: COVID-19 Desenmascarado es un estudio de cohorte longitudinal prospectivo en línea. Se formó un comité directivo internacional con el objetivo de iniciar una colaboración global. Actualmente, se han formado asociaciones con 9 países (Australia, Chipre, Grecia, Países Bajos, Polonia, España, Turquía, Reino Unido y Estados Unidos de América). Los socios de investigación han comenzado la recopilación de datos con los cuidadores de niños pequeños de 1 a 5 años al inicio, a los 3 meses, a los 6 meses y a los 12 meses. Se invita a los cuidadores a completar una encuesta en línea sobre la exposición y las experiencias relacionadas con COVID-19, el bienestar del niño, su propia salud mental y parentalidad. Análisis de datos: Los resultados primarios del estudio serán la salud mental infantil según la evaluación de las escalas del Sistema De Información De medición de Resultados Informados Por El Paciente ­ Primera Infancia (PROMIS-EC) y la salud mental del cuidador según la evaluación de la Escala de estrés, ansiedad y depresión (DASS-21). Las trayectorias/temporalidad de las dificultades de salud mental y el impacto de los factores de riesgo y de protección se analizarán utilizando modelos lineales jerárquicos, teniendo en cuenta los efectos anidados (por ejemplo, el país) y las medidas repetidas.

Risk factors associated with SARS-CoV-2 pneumonia in the pediatric population.

INTRODUCCIÓN: Hasta ahora existen pocos estudios sobre las características clínicas de la población pediátrica con neumonía por COVID-19. El objetivo de este estudio fue analizar los datos que se asocian con el desarrollo de neumonía en niños y adolescentes con infección por SARS-CoV-2 en México. MÉTODOS: Se llevó a cabo un análisis secundario de la base de datos de la Dirección General de Epidemiología del Gobierno Mexicano. Se incluyeron menores de 19 años con infección por SARS-CoV-2 confirmada mediante la prueba de retrotranscripción acoplada a la reacción en cadena de la polimerasa (RT-PCR). La variable dependiente fue el diagnóstico de neumonía. Se calcularon las razones de momios (RM) y los intervalos de confianza del 95% (IC95%). Se realizaron modelos de regresión logística múltiple para ajustar los factores asociados a neumonía. RESULTADOS: Se incluyeron 1443 niños con diagnóstico de COVID-19. La mediana de edad de los participantes fue de 12 años (rango intercuartilar 25-75: 5-16). La neumonía se presentó en 141 niños (9.8%). Los principales factores de riesgo fueron edad < 3 años (RM: 3.5; IC95%: 2.45-5.03), diabetes u obesidad (RM: 12.6; IC95%: 4.62-34.91) e inmunocompromiso (RM: 7.03; IC95%: 3.97-13.61). CONCLUSIONES: Los niños con COVID-19 menores de 3 años y con comorbilidad, especialmente diabetes u obesidad, y los inmunocomprometidos presentan mayor riesgo de desarrollar neumonía. BACKGROUND: Currently, there are a few studies on the clinical characteristics of the pediatric population with COVID-19 and pneumonia. This study aimed to analyze data associated with the development of pneumonia in children and adolescents with SARS-CoV-2 infection throughout Mexico. METHODS: We conducted a secondary analysis of the database of the Dirección General de Epidemiología of the Mexican Government. We included children under the age of 19 who were confirmed with SARS-CoV-2 infection by reverse transcription-polymerase chain reaction (RT-PCR) test. The dependent variable was the diagnosis of pneumonia. Odds ratios (OR) and 95% confidence intervals (95% CI) were calculated. Multiple logistic regression models were performed to adjust factors associated with pneumonia. RESULTS: A total of 1443 children with a COVID-19 diagnosis were included. The median age of the participants was 12 years (interquartile range 25, 75: 5, 16). Pneumonia occurred in 141 children (9.8%). The main risk factors were age < 3 years (OR, 3.5; 95%CI, 2.45-5.03); diabetes or obesity (OR, 12.6; 95%CI, 4.62-34.91); and immunocompromise (OR, 7.03; 95%CI, 3.97-13.61). CONCLUSIONS: Children < 3 years with COVID-19 and comorbidities, especially diabetes or obesity, and immunocompromised patients have a higher risk of developing pneumonia.

Diabetes and tuberculosis: a syndemic complicated by COVID-19. / Diabetes y tuberculosis: una sindemia complicada por la COVID-19.

Tuberculosis (TB) is the leading cause of infectious mortality in the world, affecting mainly developing countries (DC), while diabetes (DM) is one of the most prevalent chronic diseases. This review analyzes the fact that diabetes is currently an important risk factor for developing TB, also presenting more complicated TB, more relapses and higher mortality. The DCs and the fourth world of the large cities are those with the highest incidence of TB and an increase in DM, which will make it difficult to control tuberculosis disease. At the same time, the COVID-19 pandemic is complicating the management of both diseases due to the difficulty of access to control and treatment and the worsening of socioeconomic inequalities. It is necessary to establish a bidirectional screening for TB and DM and promote recommendations for the joint management of both diseases.

[Personal and vaccination history as factors associated with SARS-CoV-2 infection]. / Antecedentes personales y vacunales como factores asociados a la infección por SARS-CoV-2.

BACKGROUND AND OBJECTIVE: SARS-CoV-2 has been and is a major global Public Health challenge. Since the beginning of the pandemic, different comorbidities have been postulated and associated with spectra of increased severity and mortality. The objectives of this research are: 1) to analyse the factors associated with SARS-CoV-2 infection (COVID-19) in a health area in northern Spain; 2) to understand the possible role of influenza vaccination and pneumococcal vaccination in the development of COVID-19. MATERIALS AND METHOD: A test-negative case-control study was conducted. Variables related to personal and vaccination history were considered. Although the epidemiological definition of the case varied over time, the reference definition was that corresponding to 31/01/2020 in Spain. A bivariate and multivariate analysis was performed. RESULTS: The sample included 188 patients, of which 63 were cases and 125 controls. The results show that obesity increases the risk 2.4-fold of suffering this infection (IC 95% 1,301-4,521) and ARA-2 increases it 2.2-fold (95% CI 1,256-6,982). On the other hand, anti-pneumococcal vaccination of 13 serotypes showed results close to statistical significance (OR = 0.4; 95% CI 0.170-1,006). CONCLUSION: Obesity and the use of ARA-2 increases the risk of COVID-19. Scientific knowledge about factors associated with COVID-19 should be expanded. The authors consider that the present research raises the need further investigate the role of vaccines in this infection and their possible heterologous properties.

Factors associated with death in children with COVID-19 in Mexico.

INTRODUCTION: Most children affected by SARS-CoV-2 are reported to be asymptomatic, and COVID-19-related mortality in them is low; in Mexico, there is a lack of information on the subject in this population group. OBJECTIVE: To assess the risk factors associated with mortality in Mexican children with COVID-19. METHOD: Secondary analysis of the General Directorate of Epidemiology database. Children younger than 19 years, in whom SARS-CoV-2 infection was confirmed by RT-PCR, were included. RESULTS: 1443 children were included. Median age was eight years; 3.3 % were admitted to the intensive care unit, 1.8 % required assisted mechanical ventilation, and mortality was 1.9 %. In multivariate models, the development of pneumonia was the main risk factor for mortality, with an odds ratio (OR) of 6.45 (95 % CI: 1.99, 20.89); patients who required intubation had an OR of 8.75 (95 % CI: 3.23, 23.7). CONCLUSIONS: Children with COVID-19 exhibit high mortality in Mexico, and avoiding pneumonia should therefore be tried in them, especially in children younger than four years, with cardiovascular risk or immunosuppression. INTRODUCCIÓN: Se informa que la mayoría de los niños afectados por SARS-CoV-2 cursan asintomáticos y que en ellos la mortalidad por COVID-19 es baja; en México se desconoce la información al respecto en este grupo de la población. ­. OBJETIVO: Evaluar los factores de riesgo asociados a mortalidad en niños mexicanos con COVID-19. MÉTODO: Análisis secundario de la base de datos de la Dirección General de Epidemiología. Se incluyeron niños menores de 19 años, en quienes se confirmó SARS-CoV-2 mediante RT-PCR. RESULTADOS: Se incluyeron 1443 niños. La mediana de edad fue de ocho años; 3.3 % ingresó a la unidad de cuidados intensivos, 1.8 % requirió ventilación mecánica asistida y la mortalidad fue de 1.9 %. En los modelos multivariados, el desarrollo de neumonía constituyó el principal factor de riesgo de mortalidad, con razón de momios (RM) de 6.45 (IC 95 % 1.99, 20.89); los pacientes que requirieron intubación tuvieron RM de 8.75 (IC 95 % 3.23, 23.7). CONCLUSIONES: Los niños con COVID 19 tienen alta mortalidad en México, por lo que en ellos se debe procurar evitar la neumonía, especialmente en los menores de cuatro años, con riesgo cardiovascular o inmunosupresión.

[Infection and thrombosis associated with COVID-19: Possible role of the ABO blood group]. / Infección y trombosis asociada a la COVID-19: posible papel del grupo sanguíneo ABO.

BACKGROUND: SARS-CoV-2 infection is clinically very heterogeneous, varying from asymptomatic to severe clinical conditions with a fatal outcome. Some studies suggests that the ABO blood group could be a biological marker of susceptibility for the development of the disease. PATIENTS AND METHODS: We collected data from patients admitted with COVID-19 infection who had ABO blood group recorded, and analyzed the incidence by groups, compared with the global population in Navarre, as well as their main complications and evolution. RESULTS: Group O was proportionally less represented in the hospitalized patients with respect to the global population, although the difference was not statistically significant. Group B had significantly higher rates of thrombotic complications and required more admissions in intensive care units. CONCLUSION: The study suggests a lower susceptibility to infection in group O and a higher risk of complications in group B. Studies with a larger sample size are required in order to obtain significant results.

Recommendations for the care of patients with diabetes mellitus with risk factors or established cardiovascular disease and SARS-CoV-2mellitus con factores de riesgo o enfermedad cardiovascular establecida y SARS-CoV-2.

A review is carried out to examine the risk of patients suffering from diabetes mellitus in the context of general morbidity and mortality and related to infection by SARS-CoV-2. Likewise, the general recommendations for food and the prevention of comorbidities that most these patients suffer most frequently are also studied. Finally, a review of the pharmacological recommendations on both oral and parenteral treatment in the outpatient, in hospitalization and in critical states infected with SARS-CoV-2 is made.
