[Non-therapeutic hysterectomy in Mexican young females with intellectual disability: a problematized reality]. / Histerectomía no terapéutica en jóvenes mexicanas con discapacidad intelectual: una realidad problematizada.

Background: Non-therapeutic hysterectomy in girls and adolescents with intellectual disability (ID) is an acceptable practice, even when there is a lack of prescriptive ethical reason. Objectives: To determine the magnitude of the practice of hysterectomy in girls and adolescents with ID, and explore the emic factors associated with this procedure. Material and methods: Multicenter, intersectoral study with a mixed methods design. Results: The quantitative results showed that 50 of 234 reported hysterectomies corresponded to females with ID. Average age at the time of surgery was 15 ± 2.9 years. Prophylactic abdominal hysterectomy was the most common procedure, and the justifications for it were "fertility control", "menstrual hygiene management", and "risk of sexual abuse". A qualitative analysis of 15 focus groups revealed that parents' main concern was how to manage their daughters' index disease and reproductive health; they perceived menstruation positively; they expressed their fear of dying and leaving them without support, and emphasized fertility control; none of them approved hysterectomy. Conclusions: The bodies that define health policies need to create a new philosophy that avoids the reductionist approach of current biomedical model, which separates (in the health-disease process) our interdependence with other humans.

Antecedentes: La histerectomía no terapéutica en niñas y adolescentes con discapacidad intelectual (DI) es una práctica aceptable, aun cuando se carece de razón ética prescriptiva. Objetivos: Determinar la magnitud de la práctica de la histerectomía en niñas y adolescentes con DI, y explorar los factores emic asociados a esta práctica. Material y métodos: Estudio multicéntrico e intersectorial con método mixto. Resultados: Los resultados cuantitativos mostraron que 50 de 234 histerectomías reportadas correspondieron a mujeres con DI. El promedio de edad a la cirugía fue de 15 ± 2.9 años. La histerectomía abdominal profiláctica fue el procedimiento predominante y las justificaciones fueron control de fertilidad, manejo de la higiene menstrual y riesgo de abuso sexual. El análisis cualitativo de 15 grupos focales reveló que la principal preocupación de los padres fue cómo manejar la enfermedad índice y la salud reproductiva de sus hijas; percibieron positivamente la menstruación, expresaron su miedo a morir y dejarlas sin ayuda, resaltaron el control de la fertilidad y ninguno aprobó la histerectomía. Conclusiones: Los organismos que definen políticas de salud necesitan crear una nueva filosofía que evite el enfoque reduccionista del actual modelo biomédico, el cual separa (en el proceso salud-enfermedad) la interdependencia entre los seres humanos.

Antibiotics in the end-of-life phase in pediatric oncological patients with a diagnosis of terminal illness: a dilemma.

BACKGROUND: Pediatric cancer patients in the final phase of life receive antibiotics empirically. The decision to start, maintain, or stop the antibiotic administration as part of care at this stage is a dilemma. METHODS: We conducted a retrospective, descriptive, cross-sectional study including cancer patients in the final phase of life, hospitalized during the last 5 to 7 days of life. We included demographic variables, diagnoses, days of hospitalization, cultures, antibiotics used, prevalent symptoms in the last week of life, and principal diagnosis at the time of death, and performed descriptive statistics and a chord diagram. RESULTS: Twenty-two patients were included; 18 (81.81%) received antibiotic treatment. The mean age was 8.75 years. The predominant pathologies were central nervous system tumors in seven patients (31.81%). Of the total, 18 (81.81%) had an infectious diagnosis reported as bloodstream infection, followed by pneumonia in three (13.63%). The main cause of death was respiratory failure (40.9%). Of the 18 patients with an infectious diagnosis, 16 (88.88%) received empiric therapy. Predominant factors for antibiotic use were more than 7 days of hospitalization (75%), ICU admission (100%), invasive devices (88.8%), and aminergic support (100%). The predominant symptoms were dyspnea (68.18%), pain (50%), and fever (40.9%), which persisted in nine (60%), two (18.18%), and five (55.5%) patients, respectively. CONCLUSIONS: The lack of guidelines for antibiotic administration leads to excessive and potentially unnecessary use, which can lead to discomfort, prolonged hospitalization, bacterial resistance, excessive cost, and suffering without symptom control.

INTRODUCCIÓN: Los pacientes pediátricos oncológicos en la fase final de vida reciben antibióticos de forma empírica. La decisión de iniciar, mantener o suspender la administración del antibiótico como parte del cuidado en esta etapa es un dilema. MÉTODOS: Se llevó a cabo un estudio retrospectivo, descriptivo y transversal que incluyó pacientes oncológicos en fase final de vida, hospitalizados durante los últimos 5 a 7 días de vida. Se incluyeron variables demográficas, diagnósticos, días de estancia hospitalaria, cultivos, antibióticos utilizados, síntomas prevalentes en la última semana de vida y diagnóstico principal al momento de fallecer. Se realizó estadística descriptiva y un gráfico de cuerdas. RESULTADOS: Se incluyeron 22 pacientes: 18 (81.81%) recibieron manejo antibiótico. La media de edad fue de 8.75 años. Las patologías predominantes fueron tumores de sistema nervioso central en siete pacientes (31.81%). Del total, 18 (81.81%) pacientes presentaron infección del torrente sanguíneo; tres (13.63%) presentaron neumonía. La principal causa de muerte fue insuficiencia respiratoria (40.9%). De los 18 pacientes con diagnóstico infeccioso, 16 (88.88%) recibieron terapia empírica. Los factores prevalentes para el uso antibiótico fueron una estancia hospitalaria mayor a 7 días (75%), hospitalización en Unidad de Cuidados Intensivos (100%), dispositivos invasivos (88.8%) y apoyo aminérgico (100%). El síntoma prevalente fue disnea (68.18%), dolor (50%) y fiebre (40.9%), mismos que persistieron en nueve (60%), dos (18.18%) y cinco pacientes (55.5%), respectivamente. CONCLUSIONES: La falta de pautas respecto a la administración de antibióticos conlleva a su uso excesivo y potencialmente innecesario, lo cual puede ocasionar incomodidad, prolongar la hospitalización, resistencia bacteriana, costos excesivos y sufrimiento, sin control de los síntomas.

Impairments in fine motor skills in children with Acute Lymphoblastic Leukaemia. A cross-sectional study.

AIM: We evaluated fine motor skills; precision, motor integration, manual dexterity, and upper-limb coordination according to sex and risk stratification in children with Acute Lymphoblastic Leukaemia (ALL). METHODS: We evaluated twenty-nine children in the maintenance phase aged 6 to 12 years with the Bruininks-Oseretsky Test of Motor Proficiency-second edition (BOT-2), and sex and age-specific norm values of BOT-2 were used to compare our results. RESULTS: We found lower scores on the upper-limb coordination subtest, p = 0.003 and on the manual coordination composite, p = 0.008, than normative values. Most boys performed "average" on both the subtests and the composites, but girls showed lower scores with a mean difference of 7.69 (95%CI; 2.24 to 3.14), p = 0.009. Girls' scale scores on the upper-limb coordination subtest were lower than normative values, with mean difference 5.08 (95%CI; 2.35 to 7.81), p = 0.006. The mean standard score difference in high-risk patients was lower than normative on the manual coordination composite, 8.18 (95%CI; 2.26 to 14.1), p = 0.015. High-risk children also performed below the BOT-2 normative on manual dexterity 2.82 (95%CI; 0.14 to 5.78), p = 0.035 and upper limb coordination subtest 4.10 (95%CI; 1.13 to 7.05), p = 0.028. We found a decrease in fine motor precision in children with a higher BMI, rho= -0.87, p = 0.056 and a negative correlation between older age and lower manual dexterity, r= -0.41 p = 0.026; however, we did not find any correlation with the weeks in the maintenance phase. CONCLUSIONS: Fine motor impairments are common in children with ALL in the maintenance phase; it is important to identify these impairments to early rehabilitation.

Behavior of immunoglobulin G antibodies for SARS-COV-2 in Mexican pediatric patients with comorbidities: a prospective comparative cohort study.

Background: More than two years after the pandemic of COVID-19 caused by the severe acute respiratory syndrome coronavirus 2 (SARS-COV-2) there is a great lack of information. The presence of immunoglobulin G (IgG) have been related with disease severity. Patients with comorbidities could develop more severe infection; however, the evaluation of the humoral response in pediatric population are needed especially in patients with comorbidities. Our aim was to describe the behavior of IgG in pediatric patients and to know if there is a difference between patients with comorbidities. Methods: A prospective comparative cohort study was carried out in a single center from June 2020 to January 2021, with a follow-up of 6 months. The study included all the subjects with confirmatory test for SARS-CoV-2 from 1 month to 17 years 11 months, the follow-up of the disease's evolution and measurement of IgG antibodies was collected. We obtained the clinical data, and comorbidities like arterial hypertension, diabetes, obesity, and cancer, the initial symptoms were recorded as well as the evolution regarding the severity of COVID-19 and the need for hospitalization, intensive care unit or mechanical ventilation. The follow up was carried out through medical consultation with an appointment every month that included direct interrogation, examination, and peripheral blood collection for the IgG quantification. The antibodies detection was done through peripheral blood and chemiluminescence microparticle immunoassay. Results: A total of 237 patients with positive polymerase chain reaction (PCR) for SARS-COV-2 were included, of which 147 presented IgG antibodies (62%), 112 (76%) without comorbidity and 35 (24%) with comorbidities, by the sixth month only 2.7% continue with positive antibody measurements. Patients with comorbidities reach higher IgG levels than patients without comorbidities the basal titters were: 5.17 for patients without comorbidities vs. 6.96 for the group with comorbidities (P<0.001). Conclusions: We found an association between the presence of comorbidities and high levels of IgG units in pediatric patients with COVID-19. Additionally, patients with more severe course of the disease have higher levels of IgG and by the third month less than 35% have immunity.

Targeted neonatal echocardiography and lung ultrasound in preterm infants with chronic lung disease with and without pulmonary hypertension, screened using a standardized algorithm.

Introduction: Increased recognition of the development of chronic pulmonary hypertension (cPH) in preterm infants with chronic lung disease (CLD) has prompted enhanced monitoring for the identification of different phenotypes. Methods: All newborns consulted for oxygen/respiratory support dependency (CLD assessment) from January 2018 to December 2021 were included. TnECHO and LUS screening for cPH-CLD were performed at 36 weeks postmenstrual age. Cases of cPH related to increased pulmonary blood flow (cPH-IPBF) were referred to Pediatric Cardiology. The objective of the study was to identify all cases of cPH (cPH-CLD/IPBF) in the CLD patients screened and to compare outcomes. Following a standardized algorithm, cPH-CLD patients were treated with diuretics; ultrasounds taken before and after treatment were analyzed. Results: Seventy-two patients with CLD were screened. Twenty-two (30%) had cPH-CLD, and nine (12%) had cPH-IPBF. cPH infants underwent more days of mechanical ventilation, were more likely to have retinopathy of prematurity, and showed increased mortality. The LUS pattern observed in the 72 CLD patients consisted of a thickened pleural line and a B-line interstitial heterogeneous pattern; 29% of patients were found to have lung consolidations. After diuretic therapy, step-down in respiratory support occurred in 59% of neonates with cPH-CLD. A decrease in respiratory rate (RR), right ventricular output (RVO), markers of pulmonary vascular resistance (PVR), and B-line pattern was observed. In tissue Doppler imaging, biventricular diastolic function was found to be modified after diuretics. Conclusions: CLD infants with cPH showed increased morbidity and mortality. In cPH-CLD patients, a decrease in RR and step-down in respiratory support was observed after diuretic treatment. Follow-up ultrasound showed a decrease in RVO, markers of PVR, and B-lines.

Long COVID in children and adolescents: COVID-19 follow-up results in third-level pediatric hospital.

Introduction: In children, the manifestations of coronavirus disease 2019 (COVID-19) in the acute phase are considered mild compared with those in adults; however, some children experience a severe disease that requires hospitalization. This study was designed to present the operation and follow-up results of the Post-COVID-19 Detection and Monitoring Sequels Clinic of Hospital Infantil de Mexico Federico Gómez in managing children with a history of SARS-CoV-2 infection. Methods: This was a prospective study conducted from July 2020 to December 2021, which included 215 children aged 0-18 years who tested positive for SARS-CoV-2 on polymerase chain reaction and/or immunoglobulin G test. The follow-up was conducted in the pulmonology medical consultation; ambulatory and hospitalized patients were assessed at 2, 4, 6, and 12 months. Results: The median age of the patients was 9.02 years, and neurological, endocrinological, pulmonary, oncological, and cardiological comorbidities were the most commonly observed among the patients. Moreover, 32.6% of the children had persistent symptoms at 2 months, 9.3% at 4 months, and 2.3% at 6 months, including dyspnea, dry cough, fatigue, and runny nose; the main acute complications were severe pneumonia, coagulopathy, nosocomial infections, acute renal injury, cardiac dysfunction, and pulmonary fibrosis. The more representative sequelae were alopecia, radiculopathy, perniosis, psoriasis, anxiety, and depression. Conclusions: This study showed that children experience persistent symptoms, such as dyspnea, dry cough, fatigue, and runny nose, although to a lesser extent than adults, with significant clinical improvement 6 months after the acute infection. These results indicate the importance of monitoring children with COVID-19 through face-to-face consultations or telemedicine, with the objective of offering multidisciplinary and individualized care to preserve the health and quality of life of these children.

Clinical features and severe acute respiratory syndrome-coronavirus-2 structural protein-based serology of Mexican children and adolescents with coronavirus disease 2019.

Severe acute respiratory syndrome (SARS)-coronavirus (CoV)-2 infection in children and adolescents primarily causes mild or asymptomatic coronavirus disease 2019 (COVID-19), and severe illness is mainly associated with comorbidities. However, the worldwide prevalence of COVID-19 in this population is only 1%-2%. In Mexico, the prevalence of COVID-19 in children has increased to 10%. As serology-based studies are scarce, we analyzed the clinical features and serological response (SARS-CoV-2 structural proteins) of children and adolescents who visited the Hospital Infantil de México Federico Gómez (October 2020-March 2021). The majority were 9-year-old children without comorbidities who were treated as outpatients and had mild-to-moderate illness. Children aged 6-10 years and adolescents aged 11-15 years had the maximum number of symptoms, including those with obesity. Nevertheless, children with comorbidities such as immunosuppression, leukemia, and obesity exhibited the lowest antibody response, whereas those aged 1-5 years with heart disease had the highest levels of antibodies. The SARS-CoV-2 spike receptor-binding domain-localized peptides and M and E proteins had the best antibody response. In conclusion, Mexican children and adolescents with COVID-19 represent a heterogeneous population, and comorbidities play an important role in the antibody response against SARS-CoV-2 infection.

Mortality in children with cancer and SARS-CoV-2 in Latin America: A systematic review.

The new COVID-19 disease is caused by a novel coronavirus (SARS-CoV-2), that probably originated in Wuhan, China, and has currently infected 505,817,953 people and caused 6,213,876 deaths in the world. On the American continent, 152,265,980 cases and 2,717,108 deaths have been reported to WHO (World Health Organization). The Latin America and the Caribbean (LAC) region presents an epidemiological challenge due to its population's heterogeneity and socioeconomic inequality. A particularly vulnerable population is that of children with cancer, and their mortality from COVID-19 has been reported to be 3.6% globally. This work aimed to study the lethality of SARS-CoV-2 infection in children with cancer in the Latin American region. Our objective was to systematically review published scientific literature and search hospital databases in Latin America to explore mortality in this region. A median of mortality of 9.8% was found in the articles analyzed. In addition, we collected five databases from Latin American hospitals. We concluded that there was an underestimation in the mortality registry of this group of patients in the analyzed region. Therefore, although the causes are unknown, it is necessary to strengthen the case-reporting system to determine the reality in complex and particular areas such as Latin America.

Predictors of Septic Shock or Bacteremia in Children Experiencing Febrile Neutropenia Post-Chemotherapy.

BACKGROUND: Febrile neutropenia (FN) is an early indicator of infection in oncology patients post-chemotherapy. We aimed to determine clinical predictors of septic shock and/or bacteremia in pediatric cancer patients experiencing FN and to create a model that classifies patients as low-risk for these outcomes. METHODS: This is a retrospective analysis with clinical data of a cohort of pediatric oncology patients admitted during July 2015 to September 2017 with FN. One FN episode per patient was randomly selected. Statistical analyses include distribution analysis, hypothesis testing, and multivariate logistic regression to determine clinical feature association with outcomes. RESULTS: A total of 865 episodes of FN occurred in 429 subjects. In the 404 sampled episodes that were analyzed, 20.8% experienced outcomes of septic shock and/or bacteremia. Gram-negative bacteria count for 70% of bacteremias. Features with statistically significant influence in predicting these outcomes were hematological malignancy (P < .001), cancer relapse (P = .011), platelet count (P = .004), and age (P = .023). The multivariate logistic regression model achieves AUROC = 0.66 (95% CI 0.56-0.76). The optimal classification threshold achieves sensitivity = 0.96, specificity = 0.33, PPV = 0.40, and NPV = 0.95. CONCLUSIONS: This model, based on simple clinical variables, can be used to identify patients at low-risk of septic shock and/or bacteremia. The model's NPV of 95% satisfies the priority to avoid discharging patients at high-risk for adverse infection outcomes. The model will require further validation on a prospective population.

COVID-19 and Fontan: bioethical analysis derived from the need for hospital reconversion.

BACKGROUND: Among congenital heart diseases, those with univentricular physiology are the most severe with the lowest survival. Fontan surgery (FS) is the procedure of choice, as it bypasses the flow from the caval veins to the pulmonary circulation but requires close monitoring for late complications. The SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) pandemic caused nations to prioritize the availability of human and material health resources to benefit those infected. This study aimed to evaluate the clinical consequences of hospital reconversion due to the COVID-19 pandemic in a univentricular heart clinic for patients with FS from the bioethical perspective. METHODS: We conducted an analytical cross-sectional study in a captive cohort of patients with FS treated in a tertiary hospital with conversion to COVID-19 patient care. The consequences of discontinuation of follow-up were recorded. Qualitative variables were expressed as frequencies and percentages, and quantitative variables as medians and interquartile ranges (p25-p75). Comparison between the two groups was performed with the χ2 test. RESULTS: We included 51 patients with a median age of 13 years and a follow-up of 5 years. The male: female ratio was 0.88:1.12, and 41% (21) presented failures. More than 90% of the patients presented needs for medications and imaging studies. The two patients cared for in palliative care discontinued their care. CONCLUSIONS: Continuity of care must be guaranteed for all patients who require it, so health policies are needed to ensure compliance with vulnerable groups.

INTRODUCCIÓN: Entre las cardiopatías congénitas, las de fisiología univentricular son el espectro más grave y con menor supervivencia. La cirugía de Fontan es el procedimiento de elección, ya que deriva el flujo de las venas cava a la circulación pulmonar, pero requiere un seguimiento estrecho de las complicaciones tardías. La pandemia por el SARS-CoV-2 (coronavirus 2 causante del síndrome respiratorio agudo grave) condicionó que las naciones priorizaran la disposición de los recursos humanos y materiales en salud en beneficio de los infectados. El objetivo de este estudio fue evaluar las consecuencias clínicas de la reconversión hospitalaria por la pandemia de COVID-19 en una clínica de corazón univentricular de los pacientes con cirugía de Fontan desde el punto de vista bioético. MÉTODOS: Se llevó a cabo un estudio transversal analítico en una cohorte cautiva de pacientes con cirugía de Fontan atendidos en un hospital de tercer nivel con reconversión para atención de pacientes por COVID-19. Se registraron las consecuencias derivadas de la interrupción del seguimiento. Las variables cualitativas se expresaron en frecuencias y porcentajes, y las cuantitativas en medianas y rangos intercuartílicos (p25-p75). La comparación entre ambos grupos se realizó con la prueba de χ2. RESULTADOS: Se incluyeron 51 pacientes, con una mediana de edad de 13 años y seguimiento de 5 años. La relación de sexo masculino: femenino fue de 0.88:1.12, y el 41% (21) presentaron fallas. Más del 90% de los pacientes presentaron necesidades en el suministro de medicamentos y estudios de imagen. Los dos pacientes atendidos en cuidados paliativos suspendieron su atención. CONCLUSIONES: La continuidad asistencial debe estar garantizada para todos los enfermos que la requieran, por lo que se necesitan políticas de salud para que esta continuidad se cumpla en los grupos vulnerables.

The Usefulness of Intraoperative PTH as a Predictor for Successful Parathyroidectomy in Secondary Hyperparathyroidism.

Introduction: Secondary hyperparathyroidism (SHPT) is a multisystemic syndrome that affects calcium and bone homeostasis in patients with chronic kidney disease (CKD). Despite medical treatment, 1-2% of patients require parathyroidectomy annually. The use of an intraoperative parathormone protocol (IOPTH) to predict cure is still in debate, due to the lack of standardized protocols, the use of different assays, and uneven PTH clearance. This study aimed to determine the diagnostic accuracy of an IOPTH in patients with SHPT for predicting successful surgery after parathyroidectomy. Methods: About 30 patients were enrolled. A prospective observational study (cohort) was performed in patients who were submitted to parathyroidectomy by an endocrine surgeon for SHPT. All were submitted to a bilateral neck exploration with a subtotal parathyroidectomy. Three IOPTH determinations were withdrawn: at anesthetic induction (PTH0), 15 min (PTH15), and 30 min (PTH30) after completion of gland resection. Another sample was taken 24 h after the procedure (PTH24), values <150 pg/mL defined a successful surgery, and patients were assigned to the success or failure group. IOPTH drop was analyzed to predict successful surgery with drops of 70 and 90% at 15 and 30 min, respectively. Results: A total of 26 patients were included, 19 patients were in the successful group. IOPTH showed a significant difference between groups in their absolute PTH15 and PTH30 values. A significant difference was also found in their PTH drop at 30 min (81 vs. 91%, p = 0.08). For predicting a successful surgery, having a PTH drop >90% at 30 min was the most significant factor [Odds Ratio (OR) 3.0 (1.5-4) IC 95%]. Conclusions: This study points toward a stricter and staggered IOPTH protocol to predict a successful surgery. Our results suggest taking a PTH15 expecting a PTH drop of >90%. If this is not achieved, reexploration and a PTH30 sample are suggested to accurately predict success.

Risk conditions in healthcare workers of a pediatric COVID center in Mexico City / Condiciones de riesgo en el personal de salud de un centro COVID pediátrico de la Ciudad de México

Abstract Background: The new evere acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is characterized by its high capacity to transmit. Health-care personnel is highly susceptible to becoming infected. This study aimed to determine the characteristics and known risk factors for contagion and severe outcomes of SARS-CoV-2 disease in health-care personnel of a pediatric coronavirus disease (COVID) center in Mexico City. Methods: In the last week of March 2020 (at the beginning of phase 2 of the Ministry of Health's national campaign in Mexico), a study was conducted on healthcare workers of a pediatric COVID hospital in Mexico City. Using a virtual interview, we evaluated comorbidities, mobility, areas and functions where they carry out the activities, protection measures, contact history, and vaccination. According to their activities, healthcare workers were classified into the following areas: medical, nursing, other health-care personnel (researchers, nutritionists, rehabilitation, imaging, and laboratory), administrative, and other services. We compared the variables between the groups of healthcare workers with the X2 test. Results: We included 812 participants. The mean age was 41 ± 11 years, and 33% were overweight or obese, 18% were over 60 years old, and 19% had high blood pressure. Medical and nursing personnel presented a higher proportion in the use of standard protection measures. Conclusions: Among healthcare workers, there are risk conditions for the development of complications in case of SARS-CoV-2 infection. Most medical and nursing personnel use standard protective measures.

Frequency of acute stress disorder in health care workers of a tertiary level pediatric hospital during the National Safe Distance Strategy for COVID-19 prevention / Frecuencia de trastorno por estrés agudo en el personal de salud de un hospital pediátrico de tercer nivel durante la Jornada Nacional de Sana Distancia para la prevención de la COVID-19

Abstract Background: Acute stress disorder (ASD) is one of the most frequent mental illnesses occurring during sanitary emergencies. This study aimed to estimate the frequency of ASD in health care workers of a tertiary level pediatric hospital during the coronavirus disease (COVID-19) pandemic. Methods: We conducted a cross-sectional study in which health care workers completed a virtual questionnaire, including sociodemographic information and the ASD scale. Results: We analyzed 206 questionnaires. The population was divided into three groups: attending physicians, medical residents, and nursing personnel. The frequency of health care workers who showed at least nine symptoms of ASD was 88.8%. No significant differences were found between the studied groups. Conclusions: ASD is a frequent condition in health care workers in the context of the COVID-19 pandemic. We need to investigate further and assess risk and protective factors for developing this and other psychopathologies in this population.

Resumen Introducción: El trastorno por estrés agudo es una de las enfermedades mentales más frecuentemente manifestadas en emergencias sanitarias. El objetivo de este estudio fue conocer la frecuencia con la que se presentó el trastorno por estrés agudo en el personal de salud de un hospital pediátrico de tercer nivel durante la epidemia de COVID-19. Método: Se realizó un estudio transversal en el que trabajadores de la salud contestaron un cuestionario virtual que incluyó datos sociodemográficos y la Escala de Trastorno por Estrés Agudo. Resultados: Se analizaron 206 encuestas. La población se dividió en tres grupos: médicos adscritos, residentes y personal de enfermería. El 88.8% de los trabajadores de la salud reportaron más de nueve síntomas de trastorno por estrés agudo. No se encontraron diferencias significativas entre los grupos de estudio. Conclusiones: Los síntomas del trastorno por estrés agudo son frecuentes en los trabajadores de la salud en el contexto de la COVID-19. Es necesario investigar acerca de los factores de riesgo y protectores asociados al desarrollo de esta y otras psicopatologías en dicha población.

Survival in pediatric patients with cancer during the COVID-19 pandemic: scoping systematic review.

Background: Coronavirus disease (COVID)-19 has currently affected 8,015,502 million people worldwide with global mortality around 5%. Information in pediatric cancer patients is still limited, but it is emerging day by day. The objective of this scoping review was to analyze the available data associated with COVID-19 infection and mortality in pediatric cancer patients and to provide useful information to plan and design strategies in this group. Methods: A search was conducted, and eight articles were obtained for qualitative analysis; 110 patients were included, all from cross-sectional studies. At the time of publication, all the analyzed documents reported no deaths associated with COVID-19. Results: According to the information, COVID-19 infection appears to be less severe in the pediatric population in comparison with adults and does not appear to be a cause of mortality in patients with childhood cancer. Conclusions: Given the nature of preliminary reports and a short follow-up in cancer patients, it is necessary to have medium- and long-term follow-up studies to determine the effects of infection and modifications to the treatments of these patients.

Introducción: La enfermedad conocida como COVID-19 ha afectado ya a 8,015,502 millones de personas en el mundo, con una mortalidad global de aproximadamente el 5%. La información en pacientes pediátricos con cáncer es aún limitada y está surgiendo día a día. El objetivo de esta revisión sistemática fue conocer los datos disponibles sobre la COVID-19 y la mortalidad en los pacientes pediátricos con cáncer, y aportar información útil para planear y diseñar estrategias en este grupo. Métodos: Se llevó a cabo una búsqueda y se seleccionaron ocho artículos para realizar un análisis cuantitativo; se incluyeron 110 pacientes, todos provenientes de estudios transversales. Al momento de las publicaciones, no se documentaron fallecimientos asociados a la COVID-19 en los documentos analizados. Resultados: De acuerdo con la información de esta revisión sistemática, la COVID-19 parece ser menos grave que en los adultos y no parece ser causa de mortalidad en pacientes pediátricos con cáncer. Conclusiones: Dada la naturaleza de los reportes preliminares y el corto seguimiento en los pacientes con cáncer, es necesario contar con estudios de seguimiento a mediano y largo plazo para conocer los efectos de la infección y de las modificaciones del tratamiento en estos pacientes.

Clinical risk profile associated with SARS-CoV-2 infection and complications in the emergency area of a pediatric COVID-19 center / Perfil clínico de riesgo asociado a infección y complicaciones por SARS-CoV-2 en el área de urgencias de un centro pediátrico COVID-19

Abstract Background: In February 2020, the disease caused by the novel coronavirus (SARS-CoV-2), was classified as a pandemic. In the pediatric population, coronavirus disease (COVID)-19 has a reported mortality of less than 6% in complicated cases; however, the clinical characteristics and severity are not the same as those presented in the adult population. This study aimed to describe the clinical manifestations of patients younger than 18 years old and their association with the confirmation of the test and outcomes. Methods: We conducted an analytical cross-sectional study of symptoms suggestive for SARS-CoV-2 infection. All subjects with a confirmatory test for SARS-CoV-2 were included. Initial symptoms, history of influenza vaccination, and previous contact were documented, and mortality and the requirement for assisted mechanical ventilation were identified. The proportions of the variables were compared with the χ2 test. The odds ratio for a positive test and the requirement of intubation was calculated. Results: Of a total of 510 subjects, 76 (15%) were positive for SARS-CoV-2. The associated symptoms were chest pain, sudden onset of symptoms, and general malaise. The variable most associated with contagion was the exposure to a relative with a confirmed diagnosis of COVID-19. Infants and subjects without the influenza vaccine showed an increased risk for respiratory complications. Conclusions: The frequency of positivity in the test was 15% (infants and adolescents represented 64% of the confirmed cases), and the associated factors identified were contact with a confirmed case, sudden onset of symptoms, and chest pain.

Resumen Introducción: En 2019 se reportaron los primeros casos de SARS-CoV-2 (coronavirus tipo 2 del síndrome respiratorio agudo grave), causante de la COVID-19, que alcanzó el grado de pandemia en febrero de 2020. La presentación en la etapa pediátrica reporta una mortalidad menor del 6% en los casos complicados; sin embargo, las características clínicas y su gravedad no son iguales que en la población adulta. El objetivo de este estudio fue describir las manifestaciones clínicas de los pacientes menores de 18 años y su asociación con la confirmación de la prueba, la intubación endotraqueal y la muerte. Métodos: Estudio transversal analítico por cuadro sugestivo de infección por SARS-CoV-2. Se incluyeron sujetos positivos para SARS-CoV-2. Se documentaron los síntomas iniciales, los antecedentes de vacunación contra la influenza y los contactos previos, y se identificaron los desenlaces de mortalidad y requerimiento de ventilación mecánica asistida. Se compararon las proporciones de las variables con la prueba χ2 y se calculó la razón de momios para la presencia de una prueba positiva y requerir intubación. Resultados: De un total de 510 sujetos, 76 (15%) fueron positivos para SARS-CoV-2. Los síntomas asociados fueron dolor precordial, inicio súbito y malestar general. La variable asociada con mayor frecuencia el contagio fue la exposición a un familiar con COVID-19 confirmada. Los sujetos sin vacuna de la influenza presentaron un riesgo mayor de complicaciones respiratorias. Conclusiones: La frecuencia de positividad en la prueba fue del 15%. Se identificaron como factores asociados a prueba positiva el contacto con un caso confirmado de COVID-19, el inicio súbito de los síntomas y el dolor precordial.

COVID-19 pandemic: challenges ahead / Pandemia de COVID-19: retos por enfrentar

Abstract Since December 2019, health systems worldwide have faced the pandemic caused by the new severe acute respiratory syndrome coronavirus 2. The pandemic began in China and has spread throughout the world. This new coronavirus has a high transmission capacity and elevated lethality in people over 60 years old and in those with risk factors (obesity, diabetes, and systemic arterial hypertension); those characteristics have a different proportion in each country. At present, there is no specific, effective, and safe treatment to treat this virus. In this review, an analysis is made on the differences in epidemiological aspects of the disease and its presentation in pediatric patients; the poorly-based recommendation for using an empirical combination of antimalarials plus antimicrobials as antiviral treatment; the indication of intravenous steroids; and the possible influence of antihypertensive drugs on the course of the disease.

Resumen A partir de diciembre de 2019, los sistemas de salud de todos los países se han enfrentado a la pandemia causada por un nuevo coronavirus (SARS-CoV-2), el cual fue notificado por primera vez en China y se ha esparcido por todo el mundo. Este nuevo coronavirus posee una alta capacidad para transmitirse. A escala mundial la letalidad ha sido más alta en la población mayor de 60 años y en aquellos que tienen factores de riesgo (obesidad, diabetes e hipertensión arterial sistémica). Sin embargo, estas características varían en proporción en cada país. Hasta el momento no hay un tratamiento específico, eficaz y seguro para combatir este virus. En este artículo se realiza un análisis sobre las diferencias globales en los aspectos epidemiológicos y con relación a su presentación en pacientes pediátricos, así como de la recomendación, con pobre fundamento, del uso de la combinación de antimaláricos y antimicrobianos empíricos como antivirales. También se analizan la indicación de esteroides intravenosos y la posible influencia de los fármacos antihipertensivos en el curso de la enfermedad.
