[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.

Low quality of life, increased number of anti-seizure drugs, and the lack of caregiver support are associated with internalized stigma in adult Mexican patients with epilepsy.

BACKGROUND: People with epilepsy (PWE) have been subject to stigma throughout history, a factor that could compromise their performance in daily life. In Mexico, little is known about the factors that may be affecting internalized stigma. OBJECTIVE: To evaluate the internalized stigma in adult PWE, its relationship with the quality of life, cognitive and depressive symptomatology, and clinical-demographic characteristics. MATERIAL AND METHODS: We conducted a cross-sectional study with a consecutive sampling approach in patients with epilepsy treated at the National Institute of Neurology and Neurosurgery Manuel Velasco Suárez (NINNMVS). Sociodemographic and clinical data, depressive symptomatology (Beck's depression inventory, DBI), cognition (MoCA test), quality of life (QOLIE-31 scale), and internalized stigma (King's internalized stigma scale, ISS) were evaluated. Correlations were made between the continuous variables and the ISS to select those with statistical significance and include them in a multiple linear regression model, along with the dummy variables, to explain internalized stigma. RESULTS: Of 128 patients, 74 (58%) were women; 38% of the patients had more than 20 years of epilepsy evolution. In addition, 39% presented depressive symptoms, and around 60% manifested a possible cognitive impairment. The variables that showed statistical significance concerning the ISS were selected along with dummy variables for multiple linear regression analysis. The resultant model considers the QOLIE-31 total score (ß = -0.489), the number of anti-seizure drugs (ASD, ß = 0.253), and those patients without caregiver support (ß = -0.166) with an adjusted R2 value of 0.316. CONCLUSIONS: A diminishing quality of life, an increased number of ASD, and patients without caregiver support influence a slight to moderate variation of internalized stigma in Mexican PWE. Therefore, it is necessary to continue studying other possible factors that influence internalized stigma to generate effective strategies to reduce its negative effects on PWE.

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.

Changes in blood glucose level after renal transplantation in pediatrics: A study of risk factors of new-onset diabetes after transplantation.

BACKGROUND: New-onset diabetes after transplantation refers to the development of diabetes after solid organ transplantation without a history of diabetes and is related to poor graft function and lower survival rate. In the kidney transplant population, NODAT occurs in 24% of adults and 9% of children. The real incidence and risk factors in the pediatric population is unknown, which we aimed to determine in this study. METHODS: A retrospective study was conducted in patients who underwent kidney transplantation in the Pediatric Nephrology Service of the "Federico Gómez" Children's Hospital of Mexico. RESULTS: The study included 127 children divided into groups 1 and 2 (without [n = 110 patients, 86.5%] and with NODAT [n = 17 patients, 13.4%], respectively), with median ages of 14 years (interquartile range [IQR], 9-16 years) and 15 years (IQR, 13-16 years; p = .3), respectively. Cox proportional hazards analysis revealed an association between changes from baseline to 24-h postoperative blood glucose level as a risk factor of the development of NODAT. This implies that each unit increase in blood glucose level in the first hours after transplantation also increases the risk of developing diabetes (95% confidence interval, 1.011-1.021; p = <.001). CONCLUSIONS: Post-kidney transplant patients require immediate follow-up, and attention should be paid to changes in blood glucose level in the first 24 h after transplantation, as any alteration may be an early sign of development of NODAT, especially in patients with a family history of diabetes mellitus.

Donor notification of permanent deferral: a qualitative study on the perceptions and practices of notifier and blood donor in Mexico.

BACKGROUND: Informing about permanent deferral requires a process that links the notifier with the donor in a particular way. Little is known about the type of information and how it is disclosed to the donors. The current study aimed to examine perceptions and practices of notifier and blood donor within the framework of the notification process of permanent deferral and from the perspective of the notifier-blood donor relationship. METHODS: A qualitative study with in-depth interviews. The participants were 13 notifiers and 25 permanently deferred donors. Participants were recruited from a national blood bank and a state's blood bank. The entire dataset/narratives were analysed using the method of thematic analysis. RESULTS: The disclosure of permanent deferral was understood as a matter of disclosing the serological test results and their medical meaning along with a concise explanation of the deferral status with regard to future blood donation and the plan to be followed. The notifiers preferred to act in accordance with the standard protocol despite acknowledging the adverse psychological and social effects to which donors are exposed when they are informed of the possible disease and the consequent permanent deferral. Donors described a variety of psychological and social affectations. They valued honesty in the communication, the clarity of the information provided and a greater involvement of the notifier. CONCLUSION: Even though the notification process does not imply that medical care is being offered to donors, the notifier is the administrator of the well-being of the donor. Notification must not be considered as something apart from care, since it is intimately related to the health of each of the donors and their medical care.

[Legitimidad de la histerectomía para resolver el "problema" de la higiene menstrual en adolescentes con discapacidad intelectual].

Menstrual hygiene in adolescents with intellectual disability (ID) represents an extra burden for parents or primary caregivers, especially in developing countries, where social institutions, including the health system, lack the capability to help this group of teenagers and their families; hence, hysterectomy to eliminate menstrual bleeding is considered a morally acceptable resource. Hysterectomy to solve the "problem" of menstrual hygiene reflects obstacles that affect the care provided by the physician to the adolescent with ID: on one hand, the criterion of social value about a "poor quality of life," and on the other, discrimination when only socioeconomic conditions are considered rather than the lack of a social network of support and special education. In Mexico, current medical support for girls and adolescents with ID for the management of menstrual hygiene is unsatisfactory. The practice of hysterectomy with the single purpose of menstrual hygiene is ethically and morally unfair and maleficent.

La higiene menstrual en las adolescentes con discapacidad intelectual (DI) representa una carga extra para los padres o cuidadores primarios, principalmente en países en desarrollo, donde las instituciones sociales, incluyendo el sistema sanitario, no tienen la capacidad suficiente para ayudar a este grupo de adolescentes y sus familias; de ahí que la histerectomía para eliminar el sagrado menstrual sea considerada como un recurso éticamente aceptable. La histerectomía para resolver el "problema" de la higiene menstrual refleja óbices que afectan la atención que el médico otorga a la adolescente con DI: por un lado, el criterio de valía social sobre una "calidad de vida deficiente" y, por otro, la discriminación, al considerar solo las condiciones socioeconómicas y no la falta de una red social de apoyo y de educación especial. En México, la actual asistencia médica a las niñas y adolescentes con DI para el manejo de la higiene menstrual es insatisfactoria. La práctica de la histerectomía por el solo hecho de higiene menstrual resulta ser ética y moralmente injusta y maleficente.

[Preclinical horizon of depression in adults]. / Horizonte preclínico de la depresión en adultos.

OBJECTIVE: Identify factors related to preclinical depression in healthy adults, their risk factors and concordance with family doctor diagnostic. MATERIALS AND METHODS: Case-control study in adult from family medicine consulting room. Beck inventory for depression was applied. The correlation between depression and the diagnosis by the family physician was evaluated. Odds ratio (OR) was determined. RESULTS: Involved 138 patients randomly from four family medicine units (FMU) in the Northern Region of Quintana Roo, Mexico. The mean age 34.9 ± 11.4 years, 55.8% women, prevalence for depression was 26.1%. Being male OR: 3.76; 95% CI: 1.69-8.36, under 30 years OR: 2.76; 95% CI: 1.27-5.99, low socioeconomic status (SES) OR: 2.11; 95% CI: 0.97-4.59 and be married OR: 3.22; 95% CI: 1.41.-7.36 had depression risk. Diagnosis by the family physician and inventory Beck. Kappa Index 0.2, 95% CI: -0057-0176; p = 0.05. CONCLUSIONS: Almost a third of young adults have some depression degree in family medicine consulting room, it is necessary a depression screening for male patients, low SES, married, and under 30 years old, attending medical consultation familiar, for a early diagnosis and improve prognosis.

Study of the metabolic syndrome severity index as a predictive factor of a major cardiovascular event in premenopausal women with systemic lupus erythematosus. / Estudio del índice de gravedad del síndrome metabólico como factor predictivo de un episodio cardiovascular mayor en mujeres premenopáusicas con lupus eritematoso sistémico.

BACKGROUND: Patients with systemic lupus erythematosus (SLE) have an increased risk of metabolic syndrome (MS) and cardiovascular (CV) disease. MS is evaluated binary, limiting the understanding of each component's severity individually. Therefore, severity scores for MS that evaluate them separately have been developed. This study aims to determine the prognosis between MS severity and the occurrence of major adverse cardiovascular events (MACE) in SLE patients. METHODS: Ten-year follow-up cohort study. Premenopausal>18-year-old women with a previous diagnosis of SLE were included. Patients with recent CV events, pregnancy, thyroid disease, and liposuction were excluded. The variables of interest were CV events; the confounding variables, and the MS severity indexes were examined. Hazard ratios and Kaplan-Meier survival curves were estimated through Cox regression. RESULTS: A total of 238 women were analyzed: 22 presented MACE, and 216 did not. MS prevalence, measured according to consensus and ATP-III criteria, was higher in MACE patients (50 and 40,95%, respectively). The MetSx-IMC severity index was higher within the MACE group. Cox analysis showed an increase in the MetSx-IMC associated with the risk of suffering MACE in a 1.107 ratio. CONCLUSIONS: The MetSx-IMC severity index, contrary to the binary approaches, is recommended to evaluate MS as a predictor of MACE in SLE patients. Offering improved and more accurate prognosis in patients at risk of developing MCE.

Frequency of hand contact with hospital surfaces in hospitalized pediatric patients.

BACKGROUND: Hand hygiene (HH) is an important strategy for preventing health-care-associated infections (HAIs). Few programs focus on HH for family members and primary caregivers but fewer for patients. This study aimed to estimate the frequency with which hospitalized pediatric patients have hand contact with hospital surfaces. METHODS: We conducted a cross-sectional descriptive observational study consisting of three phases: the first was the creation of an observation and data collection tool, the second was the training of the monitors, and the third was the observational study of hand contact and HH opportunities in hospitalized pediatric patients. RESULTS: Over 3600 minutes of observation, 2032 HH opportunities were detected, averaging 33.8/h (SD 4.7) as determined by hand contact with hospital surfaces of hospitalized pediatric patients. In our study, infants and preschool children had the highest frequency of hand contact. CONCLUSION: The high frequency of hand contact of hospital surfaces by children suggests that hourly hand disinfection of patients and caregivers, objects and surfaces around the patients may be prevention measures that could be incorporated to reduce HAIs in pediatric hospitals.

INTRODUCCIÓN: La higiene de manos es una estrategia importante para la prevención de infecciones asociadas a la atención sanitaria. Existen pocos programas centrados en la higiene de manos para los familiares y cuidadores primarios, y aún menos para el paciente. El objetivo de este estudio fue cuantificar la frecuencia con la que los pacientes pediátricos hospitalizados tienen contacto manual con superficies hospitalarias. MÉTODOS: Se llevó a cabo un estudio observacional descriptivo transversal que constó de tres fases: la primera fue la creación de una herramienta de observación y registro de datos; la segunda fue la capacitación de los monitores y la tercera fue el estudio observacional del contacto manual y de las oportunidades de higiene de manos en pacientes pediátricos hospitalizados. RESULTADOS: Durante los 3600 minutos de observación, se detectaron 2032 oportunidades, con una media de 33.8 (DE 4.7) por hora de oportunidades de higiene de manos establecidas por contacto manual con superficies de pacientes pediátricos hospitalizados. Los lactantes y los niños en edad preescolar presentaron la mayor frecuencia de contacto manual. CONCLUSIONES: La alta frecuencia de contacto manual por parte del niño indica que medidas como la desinfección de las manos cada hora del paciente y del cuidador, así como de los objetos y superficies alrededor del paciente, podrían ser medidas útiles que deberían incluirse para prevenir las infecciones asociadas a la atención de la salud en los hospitales pediátricos.

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.

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.

A Modified Sonographic Algorithm for Image Acquisition in Life-Threatening Emergencies in the Critically Ill Newborn.

The use of routine point-of-care ultrasound (POCUS) is increasing in neonatal intensive care units (NICUs), with several centers advocating for 24 h equipment availability. In 2018, the sonographic algorithm for life-threatening emergencies (SAFE) protocol was published, which allows the assessment of neonates with sudden decompensation to identify abnormal contractility, tamponade, pneumothorax, and pleural effusion. In the study unit (with a consulting neonatal hemodynamics and POCUS service), the algorithm was adapted by including consolidated core steps to support at-risk newborns, aiding clinicians in managing cardiac arrest, and adding views to verify correct intubation. This paper presents a protocol that can be applied in the NICU and the delivery room (DR) in relation to three scenarios: cardiac arrest, hemodynamic deterioration, or respiratory decompensation. This protocol can be performed with a state-of-the-art ultrasound machine or an affordable handheld device; the image acquisition protocol is carefully detailed. This method was designed to be learned as a general competence to obtain the timely diagnosis of life-threatening scenarios; the method aims to save time but does not represent a substitute for comprehensive and standardized hemodynamic and radiological analyses by a multidisciplinary team, which might not universally be on call but needs to be involved in the process. From January 2019 to July 2022, in our center, 1,045 hemodynamic consultation/POCUS consults were performed with 25 patients requiring the modified SAFE protocol (2.3%), and a total of 19 procedures were performed. In five cases, trained fellows on call resolved life-threatening situations. Clinical examples are provided that show the importance of including this technique in the care of critical newborns.

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.

Leukocyte surface expression of the endoplasmic reticulum chaperone GRP78 is increased in severe COVID-19.

Hyperinflammation present in individuals with severe COVID-19 has been associated with an exacerbated cytokine production and hyperactivated immune cells. Endoplasmic reticulum stress leading to the unfolded protein response has been recently reported as an active player in inducing inflammatory responses. Once unfolded protein response is activated, GRP78, an endoplasmic reticulum-resident chaperone, is translocated to the cell surface (sGRP78), where it is considered a cell stress marker; however, its presence has not been evaluated in immune cells during disease. Here we assessed the presence of sGRP78 on different cell subsets in blood samples from severe or convalescent COVID-19 patients. The frequency of CD45+sGRP78+ cells was higher in patients with the disease compared to convalescent patients. The latter showed similar frequencies to healthy controls. In patients with COVID-19, the lymphoid compartment showed the highest presence of sGRP78+ cells versus the myeloid compartment. CCL2, TNF-α, C-reactive protein, and international normalized ratio measurements showed a positive correlation with the frequency of CD45+sGRP78+ cells. Finally, gene expression microarray data showed that activated T and B cells increased the expression of GRP78, and peripheral blood mononuclear cells from healthy donors acquired sGRP78 upon activation with ionomycin and PMA. Thus, our data highlight the association of sGRP78 on immune cells in patients with severe COVID-19.

A Global Perspective on PDA Management in the Extremely Premature: Shifting Trend Toward Transcatheter Closure.

Patent ductus arteriosus (PDA) is a frequently encountered defect in infants born extremely premature (≤26 weeks' gestation). Historically, closure of the PDA was performed using cyclooxygenase inhibitor medications or by surgical ligations. However, the benefits of PDA closure using these therapies have never been demonstrated, albeit studies have previously not focused on the extremely premature infants. Therefore, there was a worldwide trend toward conservative management of the PDA. With improved survival of extremely premature infants, comorbidities associated with the PDA has increased, resulting in finding alternate treatments such as transcatheter patent ductus arteriosus closure (TCPC) for this population. Currently, there is a renewed interest toward selective treatment of the PDA in this high-risk cohort of small infants. This Comprehensive Review article inspects the globally changing trends in the management of the PDA in premature infants, with a special focus on the rising adoption of TCPC. Moreover, this article compiles data from several neonatal networks worldwide to help understand the problem at hand. Understanding the current management of premature infants and their outcomes is fundamentally essential if pediatric cardiologists are to offer TCPC as a viable therapeutic option for this population. This article aims to serve as a guide for pediatric cardiologists on this topic by compiling the results on landmark clinical trials on PDA management and the controversies that arise from these trials. Comparative outcomes from several countries are presented, including interpretations and opinions of the data from experts globally. This is a step toward coming to a global consensus in PDA management in premature infants.

Characteristics and outcomes of multisystem inflammatory syndrome in children: A multicenter, retrospective, observational cohort study in Mexico.

Introduction: Multisystem inflammatory syndrome in children associated with coronavirus disease 2019 (MIS-C), a novel hyperinflammatory condition secondary to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, is associated with severe outcomes such as coronary artery aneurysm and death. Methods: This multicenter, retrospective, observational cohort study including eight centers in Mexico, aimed to describe the clinical characteristics and outcomes of patients with MIS-C. Patient data were evaluated using latent class analysis (LCA) to categorize patients into three phenotypes: toxic shock syndrome-like (TSSL)-MIS-C, Kawasaki disease-like (KDL)-MIS-C, and nonspecific MIS-C (NS-MIS-C). Risk factors for adverse outcomes were estimated using multilevel mixed-effects logistic regression. Results: The study included 239 patients with MIS-C, including 61 (26%), 70 (29%), and 108 (45%) patients in the TSSL-MIS-C, KDL-MIS-C, and NS-MIS-C groups, respectively. Fifty-four percent of the patients were admitted to the intensive care unit, and 42%, 78%, and 41% received intravenous immunoglobulin, systemic glucocorticoids, and anticoagulants, respectively. Coronary artery dilatation and aneurysms were found in 5.7% and 13.2% of the patients in whom coronary artery diameter was measured, respectively. Any cause in-hospital mortality was 5.4%. Hospitalization after ten days of symptoms was associated with coronary artery abnormalities (odds ratio [OR] 1.6, 95% confidence interval [CI] 1.2-2.0). Age ≥10 years (OR: 5.6, 95% CI: 1.4-2.04), severe underlying condition (OR: 9.3, 95% CI: 2.8-31.0), platelet count <150,000 /mm3 (OR: 4.2, 95% CI: 1.2-14.7), international normalized ratio >1.2 (OR: 3.8, 95% CI: 1.05-13.9), and serum ferritin concentration >1,500 mg/dl at admission (OR: 52, 95% CI: 5.9-463) were risk factors for death. Discussion: Mortality in patients with MIS-C was higher than reported in other series, probably because of a high rate of cases with serious underlying diseases.

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.

[What you should know of the arterial blood gases during the watch]. / Lo que debe conocerse de la gasometría durante la guardia.

Gasometry is the measurement of dissolved gases in the blood, by measuring pH, carbon dioxide pressure (pCO(2)), serum bicarbonate (HCO(3-)), and lactate and serum electrolytes: sodium, potassium and chlorine you can make a diagnosis, etiology and treatment in the critically ill patient. The aim is to provide five steps for the interpretation of blood gases by: 1. The definition of acidemia or acidosis, or alkalemia or alkalosis. 2. Defining the metabolic component or respiratory. 3. To determine the anion gap; levels above 15 ± 2 determine other likely causes of excess anions (methanol, uremia, diabetic ketoacidosis, paraldehyde, ionized, lactic acidosis, ethylene glycol and salicylates. 4. Compensation, using the Winter formula. 5. The delta gap, with the formula for determining intrinsic and metabolic alkalosis. When anion gap is normal, is calculated urinary anion gap; the value is negative if the loss is extrarenal, contrary to the positive result is renal etiology.
