Neurodevelopment outcomes in the first 5 years of the life of children with transposition of the great arteries surgically corrected in the neonatal period: systematic review and meta-analysis.

OBJECTIVES: In patients with transposition of the great arteries, surgical correction may achieve definitive treatment, so a thorough knowledge of the long-term outcomes, particularly neurodevelopment outcomes, is essential. Therefore, we conducted a systematic review and meta-analysis to study the neurodevelopment outcomes in the first 5 years of the life of children submitted to corrective surgery for transposition of the great arteries in the neonatal period. METHODS: A total of 17 studies from 18 reports were included, assessing 809 individuals with surgically corrected transposition of the great arteries. The neurodevelopmental outcomes were assessed with the Bayley Scales of Infant and Toddler Development (BSID) and the Wechsler Intelligence Scale for Children (WISC). RESULTS: Mean Mental Development Index (MDI) and Psychomotor Development Index (PDI) were within the average values from 1 to 3 years of age, although the proportion of children scoring more than 1 standard deviation below the mean in PDI, MDI, motor, and language composite scores was significantly higher than in the general population. From 4 to 5 years, mean full-scale global intelligence quotient (IQ), verbal IQ, and performance IQ scores did not differ significantly from the general population. CONCLUSION: This study revealed neurodevelopment scores within the normal range at 5 years of age in children submitted to corrective surgery for transposition of the great arteries in the neonatal period. However, these early outcomes may not adequately predict long-term outcomes. Further studies are needed to identify specific risk factors and early markers of later impairment to guide the establishment of early interventions.

Improving timely transfers from acute care to the local palliative care unit for patients at the end of life.

BACKGROUND: Despite evidence showing that nearly two thirds of the Canadian population prefer to die at home, the majority die in hospital. Honoring a patient's wish for their preferred location of death is an essential component in end-of-life care. Therefore, for those patients admitted to acute care whose choice is to transfer to a palliative care unit for end-of-life care, it is imperative that this occurs in a safe and timely manner. The General Internal Medicine ward at this local tertiary care academic center, did not have a standardized process for transferring patients at the end-of-life to the local palliative care unit. With bed calls made between Monday to Saturday at 8 am, weekday and weekend transfer times ranged between 1 to 6 hours. The aim of this project was to establish a standardized, safe and efficient patient transfer from acute care to the palliative care unit for a daily standard arrival time. METHODS: A multidisciplinary quality improvement team was formed to analyze the transfer process. Several Plan Do Study Act cycles were tested, targeting all steps of the transfer process and turnaround time. An outcome measure aiming for a turnaround time of two hours was set as the target. RESULTS: A total of fourteen patient transfers were included. Average transfer time during the weekday was reduced from a baseline average of 180.2 to 128.3 min. This change was found to be statistically significant and sustained (P<0.003). The average transfer time on weekends remained stable at 234 min. The outcome target of a 10:00 am arrival time to the palliative care unit was achieved 42% of the time. CONCLUSIONS: This project remains on-going and early data is encouraging as it met the targeted transfer time 42% of the time. Fidelity in the process measures helped to meet the targeted turnaround time of two hours for a safe and efficient transfer to the palliative care unit and ensured patients got to their preferred location for end of life care. The goal is to expand this project to other general internal medicine wards across the organization.

Interstitial Macrophages Lead Early Stages of Bleomycin-Induced Lung Fibrosis and Induce Fibroblasts Activation.

A progressive fibrosing phenotype is critical in several lung diseases. It is irreversible and associated with early patient mortality. Growing evidence has revealed pulmonary macrophages' role as modulators of the fibrotic processes. The proportion, phenotype, and function of alveolar (AM) and interstitial macrophages (IM) at the early stages of bleomycin-induced pulmonary fibrosis have not been clearly described. In this way, our study aimed to characterize these macrophage populations and investigate the effect on fibroblast activation. C57BL/6 mice were intratracheally injected with bleomycin and were sacrificed at day 3, 5, and 7 for the performance of flow cytometry and fluorescent-activated cell sorting analysis for protein and gene expression quantification. After bleomycin administration, the proportion of IM was significantly higher than that of AM, which showed a decay during the inflammatory phase, and peaked at day 7. At day 7 of the inflammatory phase, AM started shifting their phenotype from M1-like towards M2, while IM showed a M2-like phenotype. Conditioned medium derived from IM sorted at day 7 induced fibroblast activation and differentiation in myofibroblasts in vitro. Our findings indicate that IM are the largest macrophage population at the early stages of experimental pulmonary fibrosis and are secreted mediators able to activate fibroblasts, pointing to macrophage modulation as a potential therapeutic strategy to restrain progressive fibrosing lung disorders.

Factors that Delay Transfers from Acute Care to a Local Palliative Care Unit.

For patients desiring end-of-life care in a palliative care unit, ensuring a safe and timely transfer while reducing length of stay in acute care is optimal. A chart review of 130 patients was completed on those who either died in acute care or were transferred to a palliative care unit. In all, 31% of patients died in acute care and 69% were transferred to a palliative care unit. Barriers impacting a timely transfer included disposition planning, behavioural changes requiring monitoring, imminently dying patients and those awaiting medical assistance in dying. This article makes clinical recommendations to address these barriers.

Hypoxia inducible-factor 1 alpha regulates neutrophil recruitment during fungal-elicited granulomatous inflammation.

Chronic pulmonary aspergillosis (CPA) is a devastating disease with increasing prevalence worldwide. The characteristic granulomatous-like inflammation poses as the major setback to effective antifungal therapies by limiting drug access to fungi. These inflammatory lung structures are reported to be severely hypoxic; nevertheless, the underlying mechanisms whereby these processes contribute to fungal persistence remain largely unknown. Hypoxia-inducible factor 1 alpha (HIF-1α), besides being the major cellular response regulator to hypoxia, is a known central immune modulator. Here, we used a model of Aspergillus fumigatus airway infection in myeloid-restricted HIF-1α knock-out (mHif1α-/- ) mice to replicate the complex structures resembling fungal granulomas and evaluate the contribution of HIF-1α to antifungal immunity and disease development. We found that fungal-elicited granulomas in mHif1α-/- mice had significantly smaller areas, along with extensive hyphal growth and increased lung fungal burden. This phenotype was associated with defective neutrophil recruitment and an increased neutrophil death, therefore highlighting a central role for HIF-1α-mediated regulation of neutrophil function in the pathogenesis of chronic fungal infection. These results hold the promise of an improved capacity to manage the progression of chronic fungal disease and open new avenues for additional therapeutic targets and niches of intervention.

Comparison Between Continuous Positive Airway Pressure and High-Flow Nasal Cannula as Postextubation Respiratory Support in Neonates: A Systematic Review and Meta-Analysis.

OBJECTIVE: The interest in noninvasive respiratory support has been increasing, including continuous positive airway pressure and recent respiratory methods, namely high-flow nasal cannula. It is discussed if high-flow nasal cannula can reduce continuous positive airway pressure or invasive ventilation use. This systematic review and meta-analysis aimed to compare continuous positive airway pressure and high-flow nasal cannula as postextubation respiratory support in neonates. MATERIALS AND METHODS: A literature search, based on Preferred Reporting of Items of Systematic Reviews and Meta-Analyses guidelines, was conducted across MEDLINE (through PubMed), Scopus, and Web of Science in 15 years (2006-2021) assessing randomized controlled trials that compared continuous positive airway pressure with high-flow nasal cannula as postextubation interventions in neonates. The primary outcome was extubation failure at 72 hours and/or at 7 days and the secondary outcomes included air leak syndrome, pneumothorax, bronchopulmonary dysplasia, nasal trauma, abdominal distension, and mortality. RESULTS: Seven studies were included, comprising 1044 neonates. No statistically significant differences were found between high-flow nasal cannula and continuous positive airway pressure in extubation failure (at 72 hours and 7 days), air leak syndrome, pneumothorax, bronchopulmonary dysplasia, abdominal distension, and mortality. High-flow nasal cannula was associated with a lower incidence of nasal trauma (odds ratio = 0.21; 95% CI 0.08-0.52; P = .0008). Studies assessing extreme premature infants (<28 weeks) raised some efficacy and safety concerns. CONCLUSION: High-flow nasal cannula may be as effective and safe as continuous positive airway pressure, with similar extubation failure and risk of air leak syndrome, pneumothorax, bronchopulmonary dysplasia, abdominal distension, and mortality with the advantage of less nasal trauma. High-flow nasal cannula should be considered as an alternative to continuous positive airway pressure in postextubation settings in neonates. Further studies are needed to establish efficacy and safety in lower gestational ages.

Pentraxin 3 Inhibits Complement-driven Macrophage Activation to Restrain Granuloma Formation in Sarcoidosis.

Rationale: Sarcoidosis is a multisystemic inflammatory disease characterized by the formation of granulomas in response to persistent stimuli. The long pentraxin PTX3 (pentraxin 3) has emerged as a component of humoral innate immunity with essential functions in the resolution of inflammation, but its role during granuloma formation is unknown. Objectives: To evaluate PTX3 as a modulator of pathogenic signals involved in granuloma formation and inflammation in sarcoidosis. Methods: Peripheral blood mononuclear cells obtained from patients with sarcoidosis harboring loss-of-function genetic variants and gene-deleted mice were used to assess the role of PTX3 in experimental models of granuloma formation in vitro and in vivo. The identified mechanisms of granulomatous inflammation were further evaluated in tissue and BAL samples and correlated with the disease course. Measurements and Main Results: We have identified a molecular link between PTX3 deficiency and the pathogenic amplification of complement activation to promote granuloma formation. Mechanistically, PTX3 deficiency licensed the complement component C5a-mediated activation of the metabolic checkpoint kinase mTORC1 (mammalian target of rapamycin complex 1) and the reprogramming of macrophages toward increased glycolysis to foster their proliferation and aggregation. This process sustained the further recruitment of granuloma-promoting immune cells and the associated proinflammatory microenvironment and influenced the clinical course of the disease. Conclusions: Our results identify PTX3 as a pivotal molecule that regulates complement-mediated signaling cues in macrophages to restrain granulomatous inflammation and highlight the therapeutic potential of this signaling axis in targeting granuloma formation in sarcoidosis.

Introduction: Pulmonary hypertension (PH), a serious clinical condition, can lead to right ventricular systolic dysfunction (RVSD) with prognostic implications. Patients with suspected PH should undergo transthoracic echocardiography (TTE) for diagnosis and evaluation as the main screening and follow-up exam. Objective: To verify the associations of and agreement between measurements of mean pressure in the right atrium (RA) and RVSD with TTE Method: Individuals diagnosed with PH were included. All patients underwent TTE and RCC. The following were evaluated by TTE: right atrial area (RAA), mean right atrial pressure through the diameter and collapsibility of the inferior vena cava (RMAPTTE), RA strain (RAS), tricuspid annular plane systolic excursion, fractional area change, RV free wall strain, and tricuspid s' wave. Mean RA pressure (RMAPRCC) and cardiac index (CI) were evaluated through the RCC. Results: Of the 16 patients, 13 were female. The mean patient age was 44.4 (±14.9) years. An association was found between RMAPRCC and AAD, RMAPTTE, and RAS (r=0.845, r=0.621, and r=-0.523, respectively; p<0.05). There was an association between the mortality risk categories measured by the RAA and RMAPRCC measures (X2=10.42; p=0.003), with moderate agreement (k=0.44; p=0.012). RVSDJ was present in 10 patients. There was an association between RVSD (present or absent) and CI (r=0.522; p=0.04) with moderate agreement (k=0.43; p=0.037). Conclusion: The TTE and RCC measurements showed an association in the assessment of mean right atrial pressure, especially between RAA and RMAPRCC. An association with RVSD and moderate agreement between methods were also noted. (AU)

Arbovirus, herpesvirus, and enterovirus associated with neurological syndromes in adult patients of a university hospital, 2017-2018.

INTRODUCTION: Herpesviruses, enteroviruses, and arboviruses are important because of their clinical relevance and ability to cause meningitis, encephalitis, meningoencephalitis, and other diseases. The clinical virology associated with diagnostic technologies can reduce the morbidity and mortality of such neurological manifestations. Here we aimed to identify the genomes of agents that cause neurological syndromes in cerebrospinal fluid (CSF) samples from patients with suspected nervous system infections admitted to the University Hospital of the University of Campinas, São Paulo, Brazil, in 2017-2018. METHODS: CSF samples collected from adult patients with neurological syndrome symptoms and negative CSF culture results were analyzed using polymerase chain reaction (PCR), reverse transcriptase-PCR, and real-time PCR, and their results were compared with their clinical symptoms. One CSF sample was obtained from each patient. RESULTS: Viral genomes were detected in 148/420 (35.2%) CSF samples: one of 148 (0.2%) was positive for herpes simplex virus-1; two (0.5%) for herpes simplex virus-2; eight (1.9%) for varicella-zoster virus; four (1%) for Epstein-Barr virus; one (0.2%) for cytomegalovirus; 32 (7.6%) for human herpesvirus-6; 30 (7.1%) for non-polio enterovirus; 67 (16.0%) for dengue virus, three (0.7%) for yellow fever virus, and 21 (5%) for Zika virus. CONCLUSIONS: The viral genomes were found in 35.2% of all analyzed samples, showing the high prevalence of viruses in the nervous system and the importance of using a nucleic acid amplification test to detect viral agents in CSF samples.

Chylothorax in the neonate-A stepwise approach algorithm.

BACKGROUND: Chylothorax in neonates results from leakage of lymph from thoracic lymphatic ducts and is mainly congenital or posttraumatic. The clinical course of the effusion is heterogeneous, and consensus on treatment, timing, and modalities of measures has not yet been established. This review aims to present, along with levels of evidence and recommendation grades, all current therapeutic possibilities for the treatment of chylothorax in neonates. METHODS: An extensive search of publications between 1970 and 2020 was performed in the PubMed, Cochrane Database of Systematic Reviews, and UpToDate databases. A stepwise approach algorithm was proposed for both congenital and traumatic conditions to guide the clinician in a rational and systematic way for approaching the treatment of neonates with chylothorax. DISCUSSION AND CONCLUSION: The treatment strategy for neonatal chylothorax generally involves supportive care and includes drainage and procedures to reduce chyle flow. A stepwise approach starting with the least invasive method is advocated. Progression in the invasiveness of treatment options is determined by the response to previous treatments. A practical stepwise approach algorithm is proposed for both, congenital and traumatic chylothoraces.

Renal Dysplasia and Progressive Renal Failure in a Newborn with Interstitial Chromosome 4 Deletion 4q25-28.3: A New Phenotype?

The deletion of the long arm of chromosome 4 is rare, presenting with a variable phenotype depending on the chromosomic area affected. A term newborn with prenatal diagnosis of anhydramnios, dysplastic cystic kidneys, and cardiomegaly was born with generalized subcutaneous edema, several dysmorphic features, and progressive renal failure requiring dialysis. The infant continued to deteriorate and died at 52 days of age. Autopsy confirmed bilateral renal dysplasia with cysts. Array-comparative genomic hybridization (CGH) identified a large deletion on 4q25-q28.3, which is not yet described in association with renal disease. The clinical progression could be expected due to the severity of the perinatal clinical presentation.

ASSOCIATION OF SERUM VASOGENIC AND PROINFLAMMATORY FACTORS WITH CLINICAL RESPONSE TO ANTI-VASCULAR ENDOTHELIAL GROWTH FACTOR FOR DIABETIC MACULAR EDEMA.

PURPOSE: To study the role of serum biomarkers as prognostic factors for qualitative and quantitative response to anti-vascular endothelial growth factor injections for diabetic macular edema (DME). METHODS: Sixty-seven eyes with DME were treated with intravitreal bevacizumab during a 12-month follow-up period. All cases underwent a baseline workup consisting of 12 inflammatory, metabolic and prothrombotic factors. The following outcomes were evaluated at 3-month intervals until 1 year of follow-up: visual acuity, central subfield thickness (CST), macular volume (MV), % of change from baseline in CST, occurrence of a CST change < 10%, a CST change >20%, and a CST <330 µm, achieving an improvement ≥2 lines of visual acuity, achieving visual acuity ≥20/40. RESULTS: A significant improvement in CST and visual acuity was seen from third month onwards. Twenty-eight (48.1%) cases were classified as "early responders," 24 (35.8%) as "late responders", and 15 (22.4%) as "poor responders." Serum vascular endothelial growth factor-A levels were significantly lower in "poor responders" (P = 0.006). C-reactive protein (hsCRP) was associated with a limited anatomic response (<10% CST change) (P = 0.002, OR = 1.845, cutoff value of hsCRP = 1.84 mg/L). hsCRP was also negatively associated with obtaining a final CST <330 µm (P = 0.04, r2 = 0.112, OR = 0.643). Baseline visual acuity was significantly associated with 12th month visual acuity (P < 0.001, r2 = 0.602) and also with an improvement ≥2 visual acuity lines (P = 0.009, OR = 20.54). CONCLUSION: Increased high-sensitivity C-reactive protein was associated with limited anatomic response to anti-vascular endothelial growth factor treatment and persistent DME. Poor responders had significantly lower values of serum vascular endothelial growth factor-A, suggesting an alternative pathogenic pathway for persisting DME.

Conclusão: mostrou-se a relevância da atividade física para idosos realizada em espaços públicos, a partir dos benefícios de sua realização e por se tratar de uma atividade de baixo custo, no entanto, ainda é preciso a implementação de ações e estratégias para diminuir as dificuldades encontradas pelos idosos para a realização da atividade física em espaços públicos

Objective: to analyze the scientific production on physical activity for the elderly in public spaces in online journals. Method: integrative review, through 21 articles in the BDENF, Index Psychology, LILACS and MEDLINE in the period from 2008 to 2018. The following categories emerged: Benefits of the practice of physical activity performed by the elderly; and Difficulties of elderly people to perform physical activity in public spaces. Results: elderly people practicing physical activity in gymnasiums and in squares presented better performance in physical fitness test and better functional capacity than the sedentary elderly. Among the main difficulties encountered by the elderly: health problems and unfeasibility of public spaces suitable for the practice of physical activity. Conclusion: it was shown the relevance of physical activity for the elderly in public spaces, from the benefits of its accomplishment and because it is a low cost activity, however, it is still necessary to implement actions and strategies to reduce difficulties encountered by the elderly to perform physical activity in public spaces

Arbovirus, herpesvirus, and enterovirus associated with neurological syndromes in adult patients of a university hospital, 2017-2018

Abstract INTRODUCTION: Herpesviruses, enteroviruses, and arboviruses are important because of their clinical relevance and ability to cause meningitis, encephalitis, meningoencephalitis, and other diseases. The clinical virology associated with diagnostic technologies can reduce the morbidity and mortality of such neurological manifestations. Here we aimed to identify the genomes of agents that cause neurological syndromes in cerebrospinal fluid (CSF) samples from patients with suspected nervous system infections admitted to the University Hospital of the University of Campinas, São Paulo, Brazil, in 2017-2018. METHODS: CSF samples collected from adult patients with neurological syndrome symptoms and negative CSF culture results were analyzed using polymerase chain reaction (PCR), reverse transcriptase-PCR, and real-time PCR, and their results were compared with their clinical symptoms. One CSF sample was obtained from each patient. RESULTS: Viral genomes were detected in 148/420 (35.2%) CSF samples: one of 148 (0.2%) was positive for herpes simplex virus-1; two (0.5%) for herpes simplex virus-2; eight (1.9%) for varicella-zoster virus; four (1%) for Epstein-Barr virus; one (0.2%) for cytomegalovirus; 32 (7.6%) for human herpesvirus-6; 30 (7.1%) for non-polio enterovirus; 67 (16.0%) for dengue virus, three (0.7%) for yellow fever virus, and 21 (5%) for Zika virus. CONCLUSIONS: The viral genomes were found in 35.2% of all analyzed samples, showing the high prevalence of viruses in the nervous system and the importance of using a nucleic acid amplification test to detect viral agents in CSF samples.

Active human herpesvirus infections in adults with systemic lupus erythematosus and correlation with the SLEDAI score.

BACKGROUND: Human herpesviruses (HHVs) are responsible for a significant number of clinical manifestations in systemic lupus erythematous (SLE) patients. The aim of this study was to determine the frequency of active HHV infections in SLE patients and correlating them with disease activity. METHODS: Serum samples were collected from 71 SLE patients and their DNAs were extracted and analyzed to detect HHV-DNA viruses using the nucleic acid amplification technique. RESULTS: Fifteen out of the 71 (21.1%) patients tested positive for the HHV-DNA virus. Of them, 11/15 HHV-DNA-positive patients (73.3%) had SLE activity index (SLEDAI - Systemic Lupus Erythematosus Disease Activity Index) ≥8 (p = 0.0001). Active HCMV infection was the mostly frequently observed infection, occurring in 6/15 patients (40%). The frequencies of other active viral infections were 22% for HSV-1, 16.7% for HHV-7, and 5.5% for HSV-2. Viral coinfection (two or more viruses detected in the same sample) occurred in three patients (16.7%). Active HHV infections in SLE patients are more frequent in those with active SLE (≥8), who is at high risk of HHV reactivation and HCMV disease. CONCLUSION: Viral surveillance is important to identify active HHV infections that can cause clinical symptoms and other complication in SLE patients.

Phagosomal removal of fungal melanin reprograms macrophage metabolism to promote antifungal immunity.

In response to infection, macrophages adapt their metabolism rapidly to enhance glycolysis and fuel specialized antimicrobial effector functions. Here we show that fungal melanin is an essential molecule required for the metabolic rewiring of macrophages during infection with the fungal pathogen Aspergillus fumigatus. Using pharmacological and genetic tools, we reveal a molecular link between calcium sequestration by melanin inside the phagosome and induction of glycolysis required for efficient innate immune responses. By remodeling the intracellular calcium machinery and impairing signaling via calmodulin, melanin drives an immunometabolic signaling axis towards glycolysis with activation of hypoxia-inducible factor 1 subunit alpha (HIF-1α) and phagosomal recruitment of mammalian target of rapamycin (mTOR). These data demonstrate a pivotal mechanism in the immunometabolic regulation of macrophages during fungal infection and highlight the metabolic repurposing of immune cells as a potential therapeutic strategy.

The T-box transcription factor brachyury behaves as a tumor suppressor in gliomas.

The oncogene brachyury (TBXT) is a T-box transcription factor that is overexpressed in multiple solid tumors and is associated with tumor aggressiveness and poor patient prognosis. Gliomas comprise the most common and aggressive group of brain tumors, and at the present time the functional and clinical impact of brachyury expression has not been investigated previously in these neoplasms. Brachyury expression (mRNA and protein) was assessed in normal brain (n = 67), glioma tissues (n = 716) and cell lines (n = 42), and further in silico studies were undertaken using genomic databases totaling 3115 samples. Our glioma samples were analyzed for copy number (n = 372), promoter methylation status (n = 170), and mutation status (n = 1569 tissues and n = 52 cell lines) of the brachyury gene. The prognostic impact of brachyury expression was studied in 1524 glioma patient tumors. The functional impact of brachyury on glioma proliferation, viability, and cell death was evaluated both in vitro and in vivo. Brachyury was expressed in the normal brain, and significantly downregulated in glioma tissues. Loss of brachyury was associated with tumor aggressiveness and poor survival in glioma patients. Downregulation of brachyury was not associated with gene deletion, promoter methylation, or inactivating point mutations. Brachyury re-expression in glioma cells was found to decrease glioma tumorigenesis by induction of autophagy. These data strongly suggest that brachyury behaves as a tumor suppressor gene in gliomas by modulating autophagy. It is important to note that brachyury constitutes an independent positive biomarker of patient prognosis. Our findings indicate that the role of brachyury in tumorigenesis may be tissue-dependent and demands additional investigation to guide rational interventions. © 2020 Pathological Society of Great Britain and Ireland.
