Rhabdoid Tumor of the Kidney and Soft Tissues: Results from National Wilms Tumor Study-5 and Children's Oncology Group Study AREN0321.

Purpose: National Wilms Tumor Study-5 (NWTS-5) and AREN0321 evaluated the outcomes of children with rhabdoid tumor of the kidney (RTK) and malignant rhabdoid tumor of soft tissues (MRT).

Patients And Methods: Eligible patients with RTK were enrolled prospectively on NWTS-5 (1995-2002) and treated with carboplatin and etoposide alternating with cyclophosphamide (Regimen RTK). Patients with RTK or MRT were enrolled on AREN0321 (2005-2012) and received vincristine, doxorubicin, and cyclophosphamide alternating with carboplatin, cyclophosphamide, and etoposide (Regimens UH-1 or dose-reduced Revised UH-1).

Carbohydrate-mediated interactions between chloroviruses and the immune system.

Understanding the molecular mechanisms which drive and modulate host-pathogen interactions are essential when designing effective therapeutic and diagnostic approaches aimed at controlling infectious diseases. Certain large and giant viruses have recently been discovered as components of the human virome, yet little is known about their interactions with the host immune system. We have dissected the role of viral N-linked glycans during the interaction between the glycoproteins from six chloroviruses (belonging to three chlorovirus classes: NC64A, SAG, and Osy viruses) and the representative carbohydrate-binding receptors of the innate immune system.

Prolonged Immunomodulator Delivery Boosts Monocyte Exosome Secretion and Elevates Cathelicidin/LL-37 Content.

Human cathelicidin LL-37 offers significant benefits to the immune system and in treating various diseases, but its therapeutic potential is hindered by low activity and instability in physiological environments. Here, we introduce a strategy to boost LL-37 levels in exosomes derived from THP-1 monocytes by incubating cells with electrospun nanofibers containing immunomodulators (e.g.

Prenatal Tobacco Exposure, Brain Subcortical Volumes, and Gray-White Matter Contrast.

Importance: Maternal tobacco use during pregnancy (MTDP) remains a major public health challenge. However, the complete spectrum of effects of MTDP is not fully understood.

Objectives: To examine the longitudinal associations of MTDP and children's brain morphometric subcortical volume and gray-white matter contrast (GWC) development.

Treatment-induced ripple effect: a systematic review exploring the abscopal phenomenon in Glioblastoma multiforme.

Purpose: This systematic review aimed to collate and synthesize the available literature on the abscopal effect in Glioblastoma multiforme (GBM) neoplasms, focusing on the reported biochemical mechanisms driving the abscopal effect.

Methods: A systematic search was conducted in PubMed, Cochrane Database of Systematic Reviews, and Epistemonikos from inception to May 1, 2023. Studies exploring the abscopal effect in GBM were included.

Sex and gender as predictors for allograft and patient-relevant outcomes after kidney transplantation.

Background: Sex, as a biological construct, and gender, defined as the cultural attitudes and behaviours attributed by society, may be associated with allograft loss, death, cancer, and rejection. Other factors, such as recipient age and donor sex, may modify the association between sex/gender and post-transplant outcomes.

Objectives: We sought to evaluate the prognostic effects of recipient sex and, separately, gender as independent predictors of graft loss, death, cancer, and allograft rejection following kidney or simultaneous pancreas-kidney (SPK) transplantation.

Gene therapy for the heart: encapsulated viruses to the rescue.

This commentary provides an in-depth analysis and perspective on the pioneering research article titled 'Extracellular Vesicle-Encapsulated Adeno-Associated Viruses for Therapeutic Gene Delivery to the Heart'. The original study explores the innovative use of extracellular vesicle-encapsulated AAVs (EV-AAV-6 and -9) as a superior gene-delivery approach for cardiomyocytes (CMs), which not only provides increased AAV neutralizing antibody (NAb) resistance but also has implications for increased gene delivery efficacy to ischemic hearts. This study examined the efficacy of EVs isolated from the conditioned medium of AAV-6 and -9 producing HEK293T cells in combinatorial and in systems in comparison to free AAVs in the presence of the NAbs.

Telehealth in emergency medicine residency training: A model curriculum.

Emergency physicians are well-positioned to take a leadership role in telehealth, particularly in emerging categories such as triage, direct acute unscheduled care, and virtual observation. However, the growth of telehealth has outpaced curricular development in emergency medicine (EM) residency programs. This manuscript presents a model longitudinal telehealth curriculum, developed by the consensus of education experts, including representatives from the telehealth interest groups from EM's two primary specialty societies: the American College of Emergency Physicians and the Society for Academic Emergency Medicine.

ER-LD Membrane Contact Sites: A Budding Area in the Pathogen Survival Strategy.

The endoplasmic reticulum (ER) and lipid droplets (LDs) are essential organelles involved in lipid synthesis, storage, and transport. Physical membrane contacts between the ER and LDs facilitate lipid and protein exchange and thus play a critical role in regulating cellular lipid homeostasis. Recent research has revealed that ER-LD membrane contact sites are targeted by pathogens seeking to exploit host lipid metabolic processes.

Liposuction for Superficialization of Deep Hemodialysis Vascular Access: A Novel Application.

Background: More than 65% of patients with end-stage renal disease (ESRD) use arteriovenous fistulas (AVFs) for hemodialysis. The increasing incidence of comorbid ESRD and obesity (body mass index, >35 kg/m) precludes patients from kidney transplantation, resulting in a need for long-term, durable AVF access. Compared with traditional superficialization techniques for overlying adiposity, liposuction is minimally invasive and well-tolerated, allowing for earlier fistula use with lower complications.

In vitro assessment of effect of initial specimen diversion device on detection of central venous catheter contamination or colonization.

The role of initial specimen diversion devices (ISDDs) in preventing contamination of central venous catheter (CVC) blood cultures is undefined. A model to simulate CVC colonization and contamination compared standard cultures with ISDD technique. ISDD detected 100% of colonized CVCs while decreasing false-positive cultures from 36% to 16%.

Seven versus 14 days of antimicrobial therapy for severe multidrug-resistant Gram-negative bacterial infections in intensive care unit patients (OPTIMISE): a randomised, open-label, non-inferiority clinical trial.

Background: Shorter courses of antimicrobial therapy have been shown to be non-inferior to longer durations for the management of several infections. However, data on critically ill patients with severe infections by multidrug-resistant Gram-negative bacteria (MDR-GNB) are scarce. In the duratiOn of theraPy in severe infecTIons by MultIdrug-reSistant gram-nEgative bacteria (OPTIMISE) trial, we assessed the non-inferiority of 7-day versus 14-day antimicrobial therapy for patients with intensive care unit (ICU)-acquired severe infections by MDR-GNB.

Pulmonary hypertension as a prognostic marker in low-flow low-gradient aortic stenosis: Insights from invasive hemodynamics and post-TAVR outcomes.

Introduction: Pulmonary hypertension (PH) is a common and significant comorbidity in patients with low-flow low-gradient (LF-LG) aortic stenosis, impacting prognosis after transcatheter aortic valve replacement (TAVR). Non-invasive tools often fail to capture PH's full clinical impact due to inherent limitations. This study evaluates the prognostic significance of PH measured invasively and explores its implications on post-TAVR outcomes.

Neuroimaging findings of adolescent depression: A review by the Research Domain Criteria (RDoC) framework.

This review examines neuroimaging studies on adolescent depression (AD) within the Research Domain Criteria (RDoC) framework, focusing on fMRI, DTI, and EEG findings. The research highlights disrupted connectivity in several neural networks-such as the affective, reward processing, cognitive control, and default mode networks-that underpin emotional and cognitive dysfunctions in AD. Notably, hypoconnectivity in the affective and cognitive control networks correlates with deficits in emotional processing and executive functioning, while hyperactivity in the default mode network relates to excessive self-referential thoughts.

Implementing Cancer Registry Data With the PCORnet Common Data Model: The Greater Plains Collaborative Experience.

Purpose: Electronic health records (EHRs) comprise a rich source of real-world data for cancer studies, but they often lack critical structured data elements such as diagnosis date and disease stage. Fortunately, such concepts are available from hospital cancer registries. We describe experiences from integrating cancer registry data with EHR and billing data in an interoperable data model across a multisite clinical research network.

Association between in situ ventilation and human-generated aerosol exposure in meatpacking plants during the COVID-19 pandemic.

During the COVID-19 pandemic, meatpacking workers were disproportionately affected by disease. Large outbreaks at meatpacking facilities resulted in loss of life and threatened the well-being of workers across the globe. Much work was done throughout the pandemic to understand and prevent these outbreaks.

Machine Learning-Based Prediction Model for ICU Mortality After Continuous Renal Replacement Therapy Initiation in Children.

Background: Continuous renal replacement therapy (CRRT) is the favored renal replacement therapy in critically ill patients. Predicting clinical outcomes for CRRT patients is difficult due to population heterogeneity, varying clinical practices, and limited sample sizes.

Objective: We aimed to predict survival to ICUs and hospital discharge in children and young adults receiving CRRT using machine learning (ML) techniques.

Proteomic profiling of bronchoalveolar lavage fluid uncovers protein clusters linked to survival in idiopathic forms of interstitial lung disease.

Background: Idiopathic interstitial pneumonias (IIPs), such as idiopathic pulmonary fibrosis and interstitial pneumonia with autoimmune features, present diagnostic and therapeutic challenges due to their heterogeneous nature. This study aimed to identify intrinsic molecular signatures within the lung microenvironment of these IIPs through proteomic analysis of bronchoalveolar lavage fluid (BALF).

Methods: Patients with IIP (n=23) underwent comprehensive clinical evaluation including pre-treatment bronchoscopy and were compared with controls without lung disease (n=5).

Base Excision Repair in Mitotic Cells and the Role of Apurinic/Apyrimidinic Endonuclease 1 (APE1) in Post-Mitotic Transcriptional Reactivation of Genes.

Endogenous DNA damage occurs throughout the cell cycle, with cells responding differently at various stages. The base excision repair (BER) pathway predominantly repairs damaged bases in the genome. While extensively studied in interphase cells, it is unknown if BER operates in mitosis and how apurinic/apyrimidinic (AP) sites, intermediates in the BER pathway that inhibit transcriptional elongation, are processed for post-mitotic gene reactivation.

Hour of Life at Enteral Feeding Initiation and Associated Clinical Morbidity in Extremely Low-Birth-Weight Infants.

Background/objectives: Identifying nutritional interventions in extremely low-birth-weight (ELBW) infants (<1000 g) that are associated with favorable clinical outcomes is important. Delayed enteral feeding initiation (>3 days) has been associated with increased odds of developing morbidity. Therefore, the aim of this study is to evaluate the relationship between hour of life at enteral feeding initiation and associated clinical outcomes.
