ABSTRACT

OBJECTIVE: This study evaluates the ROX index's accuracy in predicting the success or failure of high-flow nasal cannula (HFNC) therapy in children under 2 years with acute respiratory failure (ARF) from lower respiratory tract infections. METHODS: From January 2018 to 2021 we conducted this multicenter retrospective cohort study, which included patients aged 2-24 months. We aimed to assess HFNC therapy outcomes as either success or failure. The analysis covered patient demographics, diagnoses, vital signs, and ROX index values at intervals from 0 to 48 h after initiating HFNC. We used bivariate analysis, repeated measures ANOVA, multivariate logistic regression, and the area under the receiver operating characteristic (AUC-ROC) curve for statistical analysis. RESULTS: The study involved 529 patients from six centers, with 198 females (37%) and a median age of 9 months (IQR: 3-15 months). HFNC therapy failed in 38% of cases. We observed significant variability in failure rates across different centers and physicians (p < .001). The ROX index was significantly associated with HFNC outcomes at all time points, showing an increasing trend in success cases over time (p < .001), but not in HFNC failure cases. Its predictive ability is limited, with AUC-ROC values ranging from 0.56 at the start to 0.67 at 48 h. CONCLUSION: While the ROX index is associated with HFNC outcomes in children under 2 years, its predictive ability is modest, impacted by significant variability among patients, physicians, and centers. These findings emphasize the need for more reliable predictive tools for HFNC therapy in this patient population.

ABSTRACT

INTRODUCTION: We aimed to identify clinical characteristics, risk factors for diagnosis, and describe outcomes among children with AHT. METHODS: We performed an observational cohort study in tertiary care hospitals from 14 countries across Asia and Ibero-America. We included patients <5 years old who were admitted to participating pediatric intensive care units (PICUs) with moderate to severe traumatic brain injury (TBI). We performed descriptive analysis and multivariable logistic regression for risk factors of AHT. RESULTS: 47 (12%) out of 392 patients were diagnosed with AHT. Compared to those with accidental injuries, children with AHT were more frequently < 2 years old (42, 89.4% vs 133, 38.6%, p < 0.001), more likely to arrive by private transportation (25, 53.2%, vs 88, 25.7%, p < 0.001), but less likely to have multiple injuries (14, 29.8% vs 158, 45.8%, p = 0.038). The AHT group was more likely to suffer subdural hemorrhage (SDH) (39, 83.0% vs 89, 25.8%, p < 0.001), require antiepileptic medications (41, 87.2% vs 209, 60.6%, p < 0.001), and neurosurgical interventions (27, 57.40% vs 143, 41.40%, p = 0.038). Mortality, PICU length of stay, and functional outcomes at 3 months were similar in both groups. In the multivariable logistic regression, age <2 years old (aOR 8.44, 95%CI 3.07-23.2), presence of seizures (aOR 3.43, 95%CI 1.60-7.36), and presence of SDH (aOR 9.58, 95%CI 4.10-22.39) were independently associated with AHT. CONCLUSIONS: AHT diagnosis represented 12% of our TBI cohort. Overall, children with AHT required more neurosurgical interventions and the use of anti-epileptic medications. Children younger than 2 years and with SDH were independently associated with a diagnosis of AHT. TYPE OF STUDY: Observational cohort study. LEVEL OF EVIDENCE: III.

ABSTRACT

Objective: To determine the short-, mid-, and long-term complications after multisystem inflammatory syndrome in children (MIS-C) over a 24-month follow-up period in a hospital in Lima, Peru, 2020-2022, and to explore differences according to the immunomodulatory treatment received and type of SARS-CoV-2 virus circulating. Methods: Ambispective 24-month follow-up study in children <14 years of age diagnosed with MIS-C at the Hospital Nacional Edgardo Rebagliati Martins (HNERM). Results: A total of 62 children were admitted with MIS-C. The most common short-term complications and serious events were intensive care unit (ICU) admission, invasive mechanical ventilation (IMV) due to respiratory failure, and shock; predominantly during the second pandemic wave (lambda predominance) and in children that received intravenous immunoglobulin (IVIG) plus a corticosteroid. Two patients died during the first wave due to MIS-C. During prospective follow-up (median of 24 months; IQR: 16.7-24), only 46.7% of patients were followed for >18-24 months. Of the total, seven (11.3%) patients were identified with some sequelae on discharge. Among the 43 remaining children, sequelae persisted in five (11.6%) cases (neurological, hematological, and skin problems). Six patients (13.9%) presented with new onset disease (hematologic, respiratory, neurological, and psychiatric disorders). One patient died due to acute leukemia during the follow-up period. None of them were admitted to the ICU or presented with MIS-C reactivation. Two patients presented persistence of coronary aneurysm until 8- and 24-month post-discharge. Conclusion: In our hospital, children with MIS-C frequently developed short-term complications and serious events during the acute phase, with less frequent complications in the mid- and long-term. More studies are required to confirm these findings.

ABSTRACT

OBJECTIVE: To describe lung mechanics in Pediatric Acute Respiratory Distress Syndrome (PARDS) associated with acute COVID-19 and MIS-C with respiratory failure. METHODS: A concurrent multicenter observational study was performed, analyzing clinical variables and pulmonary mechanics of PARDS associated with COVID-19 in 4 Pediatric intensive care units (PICU) in Peru. The subgroup analysis included PARDS associated with multisystem inflammatory syndrome in children (MIS-C), MIS-PARDS, and PARDS with COVID-19 primary respiratory infection, C-PARDS. In addition, receiver operating characteristic (ROC) curve analysis for mortality and lung mechanics was performed. RESULTS: 30 patients were included. The age was 7.5 (4-11) years, 60% were male, and mortality was 23%. 47% corresponded to MIS-PARDS and 53% to C-PARDS groups. C-PARDS had positive RT-PCR in 67% and MIS-PARDS none (p < 0.001). C-PARDS group had more profound hypoxemia (P/F ratio < 100, 86% vs. 38%, p < 0.01) and higher driving-pressure [14(10-22) vs 10(10-12) cmH2O], and lower compliance of the respiratory system (CRS) [0.5 (0.3-0.6) vs 0.7(0.6-0.8) ml/ kg/cmH2O] compared with MIS-PARDS (all p < 0.05). The ROC analysis for mortality showed that driving pressure had the best performance [AUC 0.91(95%CI0.81-1.00), with the best cut-off point of 15 cmH2O (100% sensitivity and 87% specificity). Mortality in C-PARDS was 38% and 7% in MIS-PARDS (p = 0.09). MV-free days were 12(0-23) in C-PARDS and 23(21-25) in MIS-PARDS (p = 0.02). CONCLUSION: Patients with C-PARDS have lung mechanics characteristics similar to classic moderate to severe PARDS. This was not observed in patients with MIS-C. As seen in other studies, a driving pressure ≥ 15 cmH2O was the best discriminator for mortality. These findings may help guide ventilatory management strategies for these two different presentations.

ABSTRACT

In this paper, sediments from the Santiago River were characterized to look for an alternative source of inoculum for biogas production. A proteomic analysis of methane-processing archaea present in these sediments was carried out. The Euryarchaeota superkingdom of archaea is responsible for methane production and methane assimilation in the environment. The Santiago River is a major river in México with great pollution and exceeded recovery capacity. Its sediments could contain nutrients and the anaerobic conditions for optimal growth of Euryarchaeota consortia. Batch bioreactor experiments were performed, and a proteomic analysis was conducted with current database information. The maximum biogas production was 266 NmL·L-1·g VS-1, with 33.34% of methane, and for proteomics, 3206 proteins were detected from 303 species of 69 genera. Most of them are metabolically versatile members of the genera Methanosarcina and Methanosarcinales, both with 934 and 260 proteins, respectively. These results showed a diverse euryarcheotic species with high potential to methane production. Although related proteins were found and could be feeding this metabolism through the methanol and acetyl-CoA pathways, the quality obtained from the biogas suggests that this metabolism is not the main one in carbon use, possibly the sum of several conditions including growth conditions and the pollution present in these sediments.

ABSTRACT

Fluid resuscitation with crystalloids has been used in humans for more than 100 years. In patients with trauma, sepsis or shock of any etiology, they can help modify the clinical course of the illness. However, these solutions are medications which are not side-effect free. Recently, they have been questioned in terms of quantity (fluid overload) and their composition. The most frequently used crystalloids, both in high and low-income countries, are 0.9% normal saline (NS) and Ringer's lactate. The first descriptions of the use of sodium and water solutions in humans date from the cholera epidemic which spread throughout Europe in 1831. The composition of the fluids used by medical pioneers at that time differs greatly from the 0.9% NS used routinely today. The term "physiological solution" referred to fluids which did not cause red blood cell hemolysis in amphibians in in vitro studies years later. 0.9% NS has an acid pH, a more than 40% higher chloride concentration than plasma and a strong ion difference of zero, leading many researchers to consider it an unbalanced solution. In many observational studies and clinical trials, this 0.9% NS composition has been associated with multiple microcirculation and immune response complications, acute kidney injury, and worse clinical outcomes. Ringer's lactate has less sodium than plasma, as well as other electrolytes which can cause problems in patients with traumatic brain injury. This review provides a brief summary of the most important historical aspects of the origin of the most frequently used intravenous crystalloids today.

ABSTRACT

In Mexico, cacao production is endangered by pathogenic fungi, such as Phytophthora spp. and Moniliophthora rorei, that cause black pod rot and moniliasis, respectively. In this study the biocontrol agent Paenibacillus sp. NMA1017 was tested in cacao fields against the previous diseases. The treatments applied were shade management, inoculation of the bacterial strain with or without an adherent, and use of chemical control. The statistical analysis showed that the incidence of black pod rot in tagged cacao trees diminished when the bacterium was applied (reduction of 44.24 to 19.11%). The same result was observed with moniliasis when the pods were tagged (reduction of 66.6 to 27%). The use of Paenibacillus sp. NMA1017 with an integrated management might be a solution to cacao diseases and to having a sustainable production of cacao in Mexico.

ABSTRACT

RESUMEN El objetivo del presente estudio fue describir las características de los pacientes pediátricos (entre 28 días y 14 años) hospitalizados con COVID-19 durante la tercera ola (variante ómicron) en el Hospital Nacional Edgardo Rebagliati Martins (HNERM) (Lima, Perú). En esta cohorte retrospectiva, se revisaron las historias clínicas de 122 pacientes pediátricos que fueron atendidos en el HNERM entre enero e inicios de abril del 2022 (55% varones, mediana de edad de 5 años), 77,9% durante el primer mes, y la mitad presentaron alguna comorbilidad. Se hospitalizaron principalmente por dificultad respiratoria, comorbilidad descompensada y deshidratación. El 6,6% ingresaron a cuidados intensivos, 4,9% a ventilación mecánica invasiva, 5,7% requirieron algún vasoactivo y 1,6% fallecieron. Los fármacos más usados fueron antibióticos (43,4%) y corticoides (27,1%). En conclusión, se encontró un incremento rápido de hospitalizaciones en comparación con las olas anteriores, la mayoría con evolución favorable, y con un amplio uso empírico de antibióticos.


ABSTRACT This study aimed to describe the characteristics of pediatric patients (28 days to 14 years of age) hospitalized with COVID-19 during the third wave of the pandemic (omicron variant) at the Hospital Nacional Edgardo Rebagliati Martins (HNERM) (Lima, Peru). In this retrospective cohort, we reviewed the medical records of 122 pediatric patients who attended HNERM between January and early April 2022 (55% male, median age: 5 years); 77.9% attended HNERM during the first month, and half of them had some comorbidity. Participants were hospitalized mainly for respiratory distress, decompensated comorbidity, and dehydration. Of the participants, 6.6% were admitted to intensive care, 4.9% to invasive mechanical ventilation, 5.7% required some vasoactive agent and 1.6% died. The most commonly used drugs were antibiotics (43.4%) and corticosteroids (27.1%). In conclusion, hospitalizations rapidly increased during the third wave, when compared to previous waves, most of them with favorable progression and with a wide empirical use of antibiotics.

ABSTRACT

AIMS: Systemic venous congestion is associated with an increased risk of acute kidney injury (AKI) in critically ill patients. Venous Excess Ultrasound Score (VExUS) has been proposed as a non-invasive score to assess systemic venous congestion. We aimed to evaluate the association between VExUS and AKI in patients with acute coronary syndrome (ACS). METHODS AND RESULTS: This is a prospective study including patients with the diagnosis of ACS (both ST elevation and non-ST elevation ACS). VExUS was performed during the first 24 h of hospital stay. Patients were classified according to the presence of systemic congestion (VExUS 0/≥1). The primary objective of the study was to determine the occurrence of AKI, defined by KDIGO criteria. A total of 77 patients were included. After ultrasound assessment, 31 (40.2%) patients were categorized as VExUS ≥1. VExUS ≥1 was more frequently found in inferior vs. anterior myocardial infarction/non-ST-segment elevation acute myocardial infarction (48.3 vs. 25.8 and 22.5%, P = 0.031). At each increasing degree of VExUS, a higher proportion of patients developed AKI: VExUS = 0 (10.8%), VExUS = 1 (23.8%), VExUS = 2 (75.0%), and VExUS = 3 (100%; P < 0.001). A significant association between VExUS ≥1 and AKI was found [odds ratio (OR): 6.75, 95% confidence interval (CI): 2.21-23.7, P = 0.001]. After multivariable analysis, only VExUS ≥1 (OR: 6.15; 95% CI: 1.26-29.94, P = 0.02) remained significantly associated with AKI. CONCLUSION: In patients hospitalized with ACS, VExUS is associated with the occurrence of AKI. Further studies are needed to clarify the role of VExUS assessment in patients with ACS.

ABSTRACT

BACKGROUND: High-quality surgery plays a central role in the delivery of excellent oncologic care. Benchmark values indicate the best achievable results. We aimed to define benchmark values for gallbladder cancer (GBC) surgery across an international population. PATIENTS AND METHODS: This study included consecutive patients with GBC who underwent curative-intent surgery during 2000-2021 at 13 centers, across seven countries and four continents. Patients operated on at high-volume centers without the need for vascular and/or bile duct reconstruction and without significant comorbidities were chosen as the benchmark group. RESULTS: Of 906 patients who underwent curative-intent GBC surgery during the study period, 245 (27%) were included in the benchmark group. These were predominantly women (n = 174, 71%) and had a median age of 64 years (interquartile range 57-70 years). In the benchmark group, 50 patients (20%) experienced complications within 90 days after surgery, with 20 patients (8%) developing major complications (Clavien-Dindo grade ≥ IIIa). Median length of postoperative hospital stay was 6 days (interquartile range 4-8 days). Benchmark values included ≥ 4 lymph nodes retrieved, estimated intraoperative blood loss ≤ 350 mL, perioperative blood transfusion rate ≤ 13%, operative time ≤ 332 min, length of hospital stay ≤ 8 days, R1 margin rate ≤ 7%, complication rate ≤ 22%, and rate of grade ≥ IIIa complications ≤ 11%. CONCLUSIONS: Surgery for GBC remains associated with significant morbidity. The availability of benchmark values may facilitate comparisons in future analyses among GBC patients, GBC surgical approaches, and centers performing GBC surgery.

ABSTRACT

Background: Untreated human immunodeficiency virus (HIV)-immunosuppressed pediatric patients show high morbidity and mortality from opportunistic infections. Limited cases of hyperferritinemic sepsis have been described in patients with toxoplasmosis. Case report: We describe the case of a 13-year-old female patient with a history of untreated HIV who presented with hyperferritinemic sepsis secondary to Toxoplasma gondii infection and Pneumocystis jirovecci pneumonia. She received ventilatory support, inotropic drugs, treatment for opportunistic germs, and high-dose corticosteroids, but with unfavorable evolution. Conclusions: The global approach to sepsis with elevated ferritin guides to using of therapies aimed at neutralizing the severe inflammatory response. A timely diagnosis would allow prompt treatment and minimize complications.

ABSTRACT

Introducción: En Latinoamérica, existen pocos estudios y resultados heterogéneos sobre pacientes pediátricos oncohematológicos con COVID-19. Objetivo: Describir las características clínicas y la supervivencia de pacientes pediátricos oncohematológicos con COVID-19 en un hospital de Lima-Perú, 2020-2021. Métodos: Estudio longitudinal retrospectivo de pacientes menores de 14 años hospitalizados. Los datos se recolectaron de las historias clínicas. Resultados: Incluimos 30 pacientes, mayoría hombres y escolares, predominando la fiebre, síntomas respiratorios y gastrointestinales, la neoplasia hematológica, y la enfermedad oncológica avanzada. La mayoría desarrolló enfermedad leve-moderada, pero también presentaron evolución severa con requerimiento de soporte crítico, con mortalidad alta en hospitalización (13,3%) y baja supervivencia durante el seguimiento (a los 526 días, 59,26%, IC95% 36,53 a 76,20%). La supervivencia aumentó con reinicio de la quimioterapia , y disminuyó en pacientes de condición paliativa, con soporte respiratorio y shock. Conclusiones: La mayoría desarrolló enfermedad leve-moderada. Sin embargo, el SARS-CoV-2 también puede causar afectación severa, muerte y baja supervivencia en pacientes oncohematológicos.


Introduction: In Latin America, there are few studies and heterogeneous results on pediatric oncohematology patients with COVID-19. Objective: To describe the clinical characteristics and survival of pediatric oncohematology patients with COVID-19 in a hospital in Lima-Peru, 2020-2021. Methods: Retrospective longitudinal study of hospitalized patients under 14 years of age. The data was collected from the medical records. Results: We included 30 patients, mostly men and schoolchildren, predominantly fever, respiratory and gastrointestinal symptoms, hematological neoplasia, and advanced oncological disease. The majority developed mild-moderate disease, but they also presented severe evolution requiring critical areas, with high mortality in hospitalization (13.3%) and low survival during follow-up (at 526 days, 59.26%, 95% CI 36 .53 to 76.20%). Survival increased with the start of chemotherapy, and decreased in patients in palliative condition, with respiratory support and shock. Conclusion: Most developed mild-moderate disease. However, SARS-CoV-2 can also cause severe involvement, death, and poor survival in oncohematological patients.

ABSTRACT

Many bacteria have the ability to survive in challenging environments; however, they cannot all grow on standard culture media, a phenomenon known as the viable but non-culturable (VBNC) state. Bacteria commonly enter the VBNC state under nutrient-poor environments or under stressful conditions. This review explores the concept of the VBNC state, providing insights into the beneficial bacteria known to employ this strategy. The investigation covers different chemical and physical factors that can induce the latency state, cell features, and gene expression observed in cells in the VBNC state. The review also covers the significance and applications of beneficial bacteria, methods of evaluating bacterial viability, the ability of bacteria to persist in environments associated with higher organisms, and the factors that facilitate the return to the culturable state. Knowledge about beneficial bacteria capable of entering the VBNC state remains limited; however, beneficial bacteria in this state could face adverse environmental conditions and return to a culturable state when the conditions become suitable and continue to exert their beneficial effects. Likewise, this unique feature positions them as potential candidates for healthcare applications, such as the use of probiotic bacteria to enhance human health, applications in industrial microbiology for the production of prebiotics and functional foods, and in the beer and wine industry. Moreover, their use in formulations to increase crop yields and for bacterial bioremediation offers an alternative pathway to harness their beneficial attributes.

ABSTRACT

OBJECTIVES.: Motivation for the study. There are few reports on the clinical experience of the population infected with the omicron variant of COVID-19 in Latin America, particularly in pediatric population. Main findings. There was a rapid increase in the number of hospitalizations compared to previous waves, mainly due to respiratory conditions; most patients progressed favorably. Antibiotics and corticosteroids were the most used drugs. Implications. Studying the characteristics of children hospitalized during the third wave of COVID-19 in Peru may increase the knowledge of how the omicron variant affects this population group, which will allow comparisons with possible new waves or diseases.

ABSTRACT

Budd-Chiari syndrome is caused by an obstruction of blood flow to the liver. Published cases of the antiphospholipid syndrome associated with BCS are limited in the pediatric population. We report a 15-year-old adolescent who presented with fever, ascites, and hepatosplenomegaly. Hepatic Doppler ultrasound revealed no flow in the right and middle hepatic veins and in the inferior vena cava. Abdominal tomography revealed extensive thrombosis of the inferior vena cava. During hospitalization, she was diagnosed with antiphospholipid syndrome and systemic lupus erythematosus. She was given treatment with unfractionated heparin, low molecular weight heparin, and anticoagulants. Budd-Chiari syndrome secondary to the antiphospholipid syndrome is a life-threatening disease. Timely diagnosis and treatment improve the quality of life of the patient.
