RESUMO

BACKGROUND: There was a reported increase in the antimicrobial consumption in hospitals during the COVID-19 pandemic, accompanied by an increase in infections due to multidrug-resistant (MDR) bacteria. METHODS: This retrospective time series study from intensive care units in Buenos Aires examined changes in antibiotic consumption (defined daily doses/1000 patients/day), the incidence of Gram-negative bacilli (GNB) and the mechanism of resistance. Antibiotics were categorised into group 1 (agents against MDR GNB) and group 2 (agents against non-MDR infections). Bacteriological samples included respiratory samples and blood cultures. Periods were divided into pre-pandemic (July 2019 to March 2020) and pandemic (April 2020 to March 2022). Correlation coefficients (r) were analysed and the Mann-Whitney test was performed to compare both periods. RESULTS: During the study period, GNB incidence, group 1 antibiotic consumption and resistance mechanisms increased, whereas antibiotics decreased in group 2. A significant positive correlation was seen between the consumption of antibiotics in group 1 and the incidence of GNB (r = 0.63; P < 0.001) and resistance (r = 0.52; P = 0.002). Significant differences were found between pre-pandemic and pandemic periods regarding the medians of group 1 consumption (520 [408-570] vs. 753 [495-851] DDD/1000 patients/day; P = 0.029), incidence of GNB (12 [10-13] vs. 43 [25-52.5] cases/month; P < 0.001) and resistance mechanisms (5 [4-8] vs. 17 [10-25] cases/month; P < 0.001), extended-spectrum beta lactamases (2 [1-2] vs. 6 [3-8] cases/month; P < 0.001) and metallo-beta-lactamases (0 [0-0] vs. 6 [1.75-8.5] cases/month; P < 0.001). CONCLUSION: During the COVID-19 pandemic, the rise in GNB incidence and the amount of resistance mechanisms significantly correlated with the increase in consumption of agents against MDR strains.

RESUMO

The National Reference Laboratory in Clinical Mycology of Argentina conducted a retrospective review of human coccidioidomycosis cases diagnosed by the National Mycology Laboratory Network of Argentina between 2010 and 2022 to determine the burden of the disease in the country. A total of 100 human coccidioidomycosis cases were documented, with a higher prevalence in male patients (male-to-female ratio of 1.9:1), with a median age of 41 years. Comparing the number of cases between two 10-year periods (2000-2009 and 2010-2019), the increase was 36.51% (from 63 to 86 cases). Among the 100 recorded cases, 79 tested positive using the double immunodiffusion test. Spherules were observed in 19 cases through histopathology or direct microscopic examination and the fungus was isolated in 39 cases. Thirty-six isolates were identified as Coccidioides posadasii through partial sequencing of the Ag2/PRA gene. Catamarca province had the highest number of cases, comprising 64% of the total, with an incidence rate above 1.0-2.5/100,000 inhabitants until 2018. However, there has been a recent downward trend in the region from 2018 to 2022. It is concerning that more than half of diagnosed cases were chronic pulmonary or disseminated forms, indicating a lack of early disease detection. To rectify this issue, it is imperative to conduct targeted training programs for healthcare personnel and enhance public awareness within the endemic area. This will contribute to a better understanding of the true burden of coccidioidomycosis and enable the implementation of appropriate sanitary control measures.

RESUMO

OBJECTIVE: To provide evidence for the Second Pediatric Acute Lung Injury Consensus Conference updated recommendations and consensus statements for clinical practice and future research on invasive mechanical ventilation support of patients with pediatric acute respiratory distress syndrome (PARDS). DATA SOURCES: MEDLINE (Ovid), Embase (Elsevier), and CINAHL Complete (EBSCOhost). STUDY SELECTION: We included clinical studies of critically ill patients undergoing invasive mechanical ventilation for PARDS, January 2013 to April 2022. In addition, meta-analyses and systematic reviews focused on the adult acute respiratory distress syndrome population were included to explore new relevant concepts (e.g., mechanical power, driving pressure, etc.) still underrepresented in the contemporary pediatric literature. DATA EXTRACTION: Title/abstract review, full text review, and data extraction using a standardized data collection form. DATA SYNTHESIS: The Grading of Recommendations Assessment, Development and Evaluation approach was used to identify and summarize relevant evidence and develop recommendations, good practice statements and research statements. We identified 26 pediatric studies for inclusion and 36 meta-analyses or systematic reviews in adults. We generated 12 recommendations, two research statements, and five good practice statements related to modes of ventilation, tidal volume, ventilation pressures, lung-protective ventilation bundles, driving pressure, mechanical power, recruitment maneuvers, prone positioning, and high-frequency ventilation. Only one recommendation, related to use of positive end-expiratory pressure, is classified as strong, with moderate certainty of evidence. CONCLUSIONS: Limited pediatric data exist to make definitive recommendations for the management of invasive mechanical ventilation for patients with PARDS. Ongoing research is needed to better understand how to guide best practices and improve outcomes for patients with PARDS requiring invasive mechanical ventilation.

RESUMO

Introducción. Durante el invierno, los lactantes con infecciones respiratorias agudas bajas (IRAB) sobrecargan los recursos sanitarios. En la Ciudad Autónoma de Buenos Aires, 35 000 niños son asistidos anualmente en hospitales; se interna el 8-10 % en unidades generales, y el 5-12 % de ellos, en unidades de terapia intensiva. En 2017, el Departamento de Salud Materno-Infantil de dicha ciudad incluyó la oxigenoterapia por cánula nasal de alto flujo (CNAF) en el protocolo IRAB en unidades generales de tres hospitales. El objetivo de este trabajo es describir los resultados y explorar potenciales factores relacionados con el fracaso terapéutico. Métodos. Estudio prospectivo descriptivo que incluyó a lactantes < 18 meses hospitalizados por IRAB en 3 hospitales (Durand, Elizalde, Gutiérrez), de junio a septiembre de 2017. Todos los niños incapaces de cumplir los objetivos terapéuticos con bajo flujo recibieron CNAF, y se consideró fracaso de soporte el ingreso a Terapia Intensiva. Resultados. De 522 pacientes hospitalizados por IRAB, el 39,7 % requirieron CNAF. No se observaron diferencias basales significativas entre pacientes con CNAF y con oxigenoterapia convencional. Solo el 8,7 % de los pacientes con CNAF presentaron fracaso. Los pacientes con éxito del soporte mostraron un descenso de la frecuencia respiratoria significativamente mayor y más sostenido en el tiempo que aquellos con fracaso (p < 0,01). No se registraron complicaciones. Conclusión. La implementación protocolizada de CNAF en unidades generales fue una medida segura. Los pacientes con fracaso del soporte mostraron una menor disminución en la frecuencia respiratoria a lo largo del tratamiento.


Introduction. During the winter, infants with acute lower respiratory tract infection (ALRTI) overburden health resources. In the Autonomous City of Buenos Aires, 35 000 children are seen at the hospitals every year; 8-10 % of them are admitted to the general hospitalization ward and 5-12 % of these, to the intensive care unit (ICU). In 2017, the Department of Maternal and Child Health of the Autonomous City of Buenos Aires included high flow nasal cannula (HNFC) oxygen therapy in the ALRTI protocol in the general ward of 3 hospitals. The objective of this study was to describe its outcomes and explore the potential factors related to therapeutic failure. Methods. Prospective, descriptive study with infants < 18 months old hospitalized due to ALRTI in 3 hospitals (Durand, Elizalde, Gutiérrez) between June and September 2017. All children unable to comply with low-flow therapeutic targets received HNFC oxygen therapy; admission to the ICU was considered a failure. Results. Out of 522 patients hospitalized due to ALRTI, 39.7% required HNFC oxygen therapy. No significant baseline differences were observed between patients receiving HNFC and conventional oxygen therapy. Failure was observed in only 8.7% of patients with HNFC oxygen therapy. The decrease in respiratory rate was significantly greater and longer in patients with support success versus those with failure (p < 0.01). No complications were recorded. Conclusion. The implementation of HNFC oxygen therapy under a protocol in the general wards was a safe measure. Patients with therapeutic failure showed a smaller reduction in respiratory rate during treatment.

RESUMO

PURPOSE: Gender disparities in healthcare are striking, notwithstanding an increase in female students and physicians. Underrepresentation of women in leadership positions is well-documented; however, information from low and middle-income countries (LMICs) is still sparse. The Argentinian Society of Intensive Care Medicine (SATI) aimed to characterize the gender composition in Argentine ICUs. METHODS AND RESULTS: Between 8/1/2018 and 1/1/2019, 131 questionnaires were submitted to ICU Department Chairs of SATI research networks. Gender distribution of the different staffing levels, board certification and hospital characteristics were recorded. One-hundred and four were completed, including 2186 physicians; 44% were female. Female participation decreased with highest responsibility: only 23% of Department Chairs were female (P = .002 vs. the rest of the staffing categories, adjusted for multiple comparisons). Residents exhibited the highest proportion of female physicians (47%). Board certification was similar for both sexes (62.3% vs. 62.2%, P = .97). Female/male distribution in public and private hospitals was 47%/53% and 40/60% (P < .01), respectively. CONCLUSION: Our data provide evidence of an important gender gap in ICU management in a LMIC. Women were poorly represented in the leadership positions, although qualifications were similar to men. Moreover, female physicians worked more frequently in the public health subsector, usually underfinanced in LMICs-a surrogate of a gender pay gap.

RESUMO

OBJECTIVE: To assess the performance of the Pediatric Index of Mortality 3 score in a population of children admitted to PICUs in Argentina. DESIGN: Prospective, national, multicenter study. SETTING: Forty-nine PICUs located in Argentina belonging to public and private institutions. PATIENTS: All children between 1 month and 16 years old admitted to the participating PICUs between May 15, 2016, and February 15, 2017. INTERVENTIONS: None. MEASUREMENT AND MAIN RESULTS: A total of 6,602 patients were enrolled in the study. The observed mortality was 8% (531/6,602), whereas mortality predicted by Pediatric Index of Mortality 3 was 6.16% (407 deaths). The standardized mortality rate was 1.3 (95% CI, 1.20-1.42). The area under the receiver operating characteristic curve was 0.83 (95% CI, 0.82-0.85). The Hosmer-Lemeshow test showed that the difference between the mortality observed and the mortality predicted by Pediatric Index of Mortality 3 was statistically significant (χ, 135.63; p < 0.001). CONCLUSIONS: The Pediatric Index of Mortality 3 score adequately discriminated patients who died from those who survived in our population. However, the observed mortality was higher than predicted by the score. The use of an updated instrument such as Pediatric Index of Mortality 3 will allow an actual comparison between pediatric intensive care provided in the country and care provided internationally. This might also allow future planning of pediatric intensive care services in Argentina.

RESUMO

ABSTRACT Graphium basitruncatum, a synanamorph of Pseudoallescheria has been rarely reported in human infections. We report a case of subcutaneous phaeohyphomycosis caused by this fungus in a heart transplant recipient. We also describe the phenotypic, molecular methods and matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) used to achieve isolate identification.

RESUMO

Cellular immune response was evaluated in lymph nodes and lung with different granulomatous lesions from cattle naturally infected with Mycobacterium bovis. For this purpose, we assessed pro-inflammatory and anti-inflammatory cytokines by immunohistochemical assays. Immunoreaction was observed for all the cytokines analyzed. Fourteen animals displayed advanced stage IV granulomas, with intense immunoreactivity to IFN-γ and TGF-ß in areas of caseous necrosis, macrophages and lymphocytes. Seven animals showed stage III granuloma, with high immunoreactivity to IFN-γ (average of 44.5% immunoreactive cells) and moderate to TNF-α and to the anti-inflammatory cytokines IL-10 and TGF-ß, in relation to the proliferation of fibroblasts in granuloma periphery We found satellite stage I granulomas in 4 bovines and stage II granulomas in 2 bovines, which exhibited low immunostaining response (-13%). Cytokine expression in stage III and IV granulomas was significant, with predominance of immunoreactivity to IFN-γ, thus suggesting a strong, longstanding local immune response mediated by macrophages and epithelioid cells. In addition, these two stages displayed lower reactivity to IL-10; which suggests a deficit of anti-inflammatory cytokines, suppressed immunity and persistence of the infection. High expression of TGF-ß could indicate a chronic process with greater tissue damage and fibrosis. Numerous bacilli observed in necrotic areas in stage III and IV granulomas with low expression of IL-1ß suggest failure in the immune response with bacterial multiplication. In this study, evidence of in situ presence of cytokines demonstrates these cytokines are involved in the development and evolution of bovine tuberculosis granulomas.
