PRISM como predictor de mortalidad en la unidad de cuidados intensivos pediátricos del Instituto Nacional de Salud del Niño, Perú 2012

Introducción: La escala de PRISM es un predictor de mortalidad pediátrico que considera el riesgo de morir a partir del grado de afectación de 14 parámetros fisiológicos. Éste ha sido aplicado en diferentes partes del mundo, mostrando algunas discrepancias en su poder predictivo. Objetivos: Evaluar el rendimiento del escore PRISM como predictor de mortalidad de los pacientes hospitalizados en la Unidad de Cuidados Intensivos Pediátricos (UCIP) del Instituto Nacional de Salud del Niño (INSN) en Lima, Perú. Material y Método: Se analizó la base de datos de pacientes ingresados a la UCIP-INSN durante el año 2012. Se calculó la curva ROC como medida de capacidad discriminativa. La calibración fue evaluada con la prueba de Hosmer y Lemeshow. También se calculó la tasa de mortalidad estandarizada (TME). Resultados: De un total de 388 casos el 17,3% fallecieron. Según escore de PRISM, el 91,1% tuvo un “bajo riesgo”, el 7,1% un “moderado riesgo” y el 1,8% “alto riesgo”. Se encontró asociación entre las categorías del PRISM y mortalidad (p<0,001). La curva ROC para PRISM fue 0,73 (IC95%: 0,66-0,80), la TME fue 1,01 y la calibración fue buena (p=0,65). Conclusiones: El escore PRISM muestra un rendimiento adecuado como predictor de mortalidad

Possible Vertical Transmission of Bartonella bacilliformis in Peru

A 22-day-old male was admitted with a 2-day history of irritability, dyspnea, jaundice, fever, and gastrointestinal bleeding. A thin blood smear was performed, which showed the presence of intraerythrocyte bacteria identified as Bartonella bacilliformis, and subsequently, the child was diagnosed with Carrion's disease. The diagnosis was confirmed by specific polymerase chain reaction. The child was born in a non-endemic B. bacilliformis area and had not traveled to such an area before hospitalization. However, the mother was from an endemic B. bacilliformis area, and posterior physical examination showed the presence of a wart compatible with B. bacilliformis in semi-immune subjects. These data support vertical transmission of B. bacilliformis

Factors associated with hemoglobin levels in children under 6 months of age hospitalized in a pediatric center in Peru

Introduction: Anemia is a condition in which there is a low concentration of hemoglobin (Hb) levels. Although many causes of anemia have been identied, there are few studies in which they are related to epidemiological factors in the rst months of life. Objective: To determine the factors associated with hemoglobin levels in children under 6 months of age hospitalized in a specialized pediatric center in Peru. Methods: Cross-sectional study in children under 6 months of age hospitalized in the medical services of a pediatric center during the year 2017, 267 medical records were reviewed, emphasizing clinical and epidemiological characteristics. Results: 61.4% of the infants were female, and only 6.7% of the proportion of the population studied were less than 1 month old. 6.7% had low birth weight, and 53.2% had a normal delivery. The level of anemia in hospitalized children under 6 months of age is 66.7%. Conclusions:According to the bivariate analysis, a signicant association was found between hemoglobin levels with the variables age, nutritional status of weight for length and hospital causes. Regarding the multivariate analysis, only an association was found between age and the median Hb present in boys and girls aged 0 to 5 months hospitalized in a pediatric center in Peru

A systematic review and meta-analysis of the effect of dispatcher-assisted CPR on outcomes from sudden cardiac arrest in adults and children

Background: Dispatcher-assisted cardiopulmonary resuscitation (DA-CPR) has been reported in individual studies to significantly increase the rate of bystander CPR and survival from cardiac arrest. Methods: We undertook a systematic review and meta-analysis to evaluate the impact of DA-CPR programs on key clinical outcomes following out-of-hospital cardiac arrest. We searched the PubMED, EMBASE, CINAHL, ERIC and Cochrane Central Register of Controlled Trials databases from inception until July 2018. Eligible studies compared systems with and without dispatcher-assisted CPR programs. The results of included studies were classified into 3 categories for the purposes of more accurate analysis: comparison of outcomes in systems with DA-CPR programs, case-based comparison of DA-CPR to bystander CPR, and case-based comparisons of DA-CPR to no CPR before EMS arrival. The GRADE system was used to assess certainty of evidence at an outcome level. We used random-effects models to produce summary effect sizes across all outcomes. Results: Of 5531 citations screened, 33 studies were eligible for inclusion. All included studies were observational. Evidence certainty across all outcomes was assessed as low or very low. In system-level and patient-level comparisons, the provision of DA-CPR compared with no DA-CPR was consistently associated with improved outcome across all analyses. Comparison of DA-CPR to bystander CPR produced conflicting results. Findings were consistent across sensitivity analyses and the pediatric sub-group. Conclusion: These results support the recommendation that dispatchers provide CPR instructions to callers for adults and children with suspected OHCA. Review registration: PROSPERO- CRD42018091427

P-COSCA (Pediatric Core Outcome Set for Cardiac Arrest) in children : an advisory statement from the International Liaison Committee on Resuscitation

Studies of pediatric cardiac arrest use inconsistent outcomes, including return of spontaneous circulation and short-term survival, and basic assessments of functional and neurological status. In 2018, the International Liaison Committee on Resuscitation sponsored the COSCA initiative (Core Outcome Set After Cardiac Arrest) to improve consistency in reported outcomes of clinical trials of adult cardiac arrest survivors and supported this P-COSCA initiative (pediatric COSCA). The P-COSCA Steering Committee generated a list of potential survival, life impact, and economic impact outcomes and assessment time points that were prioritized by a multidisciplinary group of healthcare providers, researchers, and parents/caregivers of children who survived cardiac arrest. Then, expert panel discussions achieved consensus regarding the core outcomes, the methods to measure those core outcomes, and the timing of the measurements. The P-COSCA includes assessment of survival, brain function, cognitive function, physical function, and basic daily life skills. Survival and brain function were assessed at discharge or 30 days (or both if possible) and between 6 and 12 months postarrest. Cognitive function, physical function, and basic daily life skills were assessed between 6 and 12 months after cardiac arrest. Because many children have prearrest comorbidities, the P-COSCA also includes documentation of baseline (ie, prearrest) brain function and calculation of changes after cardiac arrest. Supplementary outcomes of survival, brain function, cognitive function, physical function, and basic daily life skills are assessed at 3 months and beyond 1 year after cardiac arrest if resources are available

The effect of alternative methods of cardiopulmonary resuscitation — Cough CPR, percussion pacing or precordial thump — on outcomes following cardiac arrest. A systematic review

Background Cardiopulmonary resuscitation (CPR) improves cardiac arrest survival. Cough CPR, percussion pacing and precordial thump have been reported as alternative CPR techniques. We aimed to summarise in a systematic review the effectiveness of these alternative CPR techniques. Methods We searched Ovid MEDLINE, EMBASE and the Cochrane Library on 24/08/2020. We included randomised controlled trials, observational studies and case series with five or more patients. Two reviewers independently reviewed title and abstracts to identify studies for full-text review, and reviewed bibliographies and ‘related articles’ (using PubMed) of full-texts for further eligible studies. We extracted data and performed risk-of-bias assessments on studies included in the systematic review. We summarised data in a narrative synthesis, and used GRADE to assess evidence certainty. Results We included 23 studies (cough CPR n = 4, percussion pacing n = 4, precordial thump n = 16; one study studied two interventions). Only two (both precordial thump) had a comparator group (‘standard’ CPR). For all techniques evidence certainty was very low. Available evidence suggests that precordial thump does not improve survival to hospital discharge in out-of-hospital cardiac arrest. The review did not find evidence that cough CPR or percussion pacing improve clinical outcomes following cardiac arrest. Conclusion Cough CPR, percussion pacing and precordial thump should not be routinely used in established cardiac arrest. In specific inpatient, monitored settings cough CPR (in conscious patients) or percussion pacing may be attempted at the onset of a potential lethal arrhythmia. These must not delay standard CPR efforts in those who lose cardiac output

2017 International Consensus on Cardiopulmonary Resuscitation and Emergency Cardiovascular Care Science With Treatment Recommendations Summary

The International Liaison Committee on Resuscitation has initiated a near-continuous review of cardiopulmonary resuscitation science that replaces the previous 5-year cyclic batch-and-queue approach process. This is the first of an annual series of International Consensus on Cardiopulmonary Resuscitation and Emergency Cardiovascular Care Science With Treatment Recommendations summary articles that will include the cardiopulmonary resuscitation science reviewed by the International Liaison Committee on Resuscitation in the previous year. The review this year includes 5 basic life support and 1 paediatric Consensuses on Cardiopulmonary Resuscitation and Emergency Cardiovascular Care Science With Treatment Recommendations. Each of these includes a summary of the science and its quality based on Grading of Recommendations, Assessment, Development, and Evaluation criteria and treatment recommendations. Insights into the deliberations of the International Liaison Committee on Resuscitation task force members are provided in Values and Preferences sections. Finally, the task force members have pri-oritised and listed the top 3 knowledge gaps for each population, intervention, comparator, and outcome question.

Improved functionalization of oleic acid-coated iron oxide nanoparticles for biomedical applications

Superparamagnetic iron oxide nanoparticles can providemultiple benefits for biomedical applications in aqueous environments such asmagnetic separation or magnetic resonance imaging. To increase the colloidal stability and allow subsequent reactions, the introduction of hydrophilic functional groups onto the particles’ surface is essential. During this process, the original coating is exchanged by preferably covalently bonded ligands such as trialkoxysilanes. The duration of the silane exchange reaction, which commonly takes more than 24 h, is an important drawback for this approach. In this paper, we present a novel method, which introduces ultrasonication as an energy source to dramatically accelerate this process, resulting in high-quality waterdispersible nanoparticles around 10 nmin size. To prove the generic character, different functional groups were introduced on the surface including polyethylene glycol chains, carboxylic acid, amine, and thiol groups. Their colloidal stability in various aqueous buffer solutions as well as human plasma and serum was investigated to allow implementation in biomedical and sensing applications.status: publishe
