Preparing for stormy weather: building VA health system resilience for dialysis emergency preparedness in the era of climate change.

Purpose Of Review: Climate change has been implicated as the driver for the increasing number, intensity, duration, and consequences of catastrophic weather events. As a result of extreme weather events, climate change has also been implicated as an important mediator of adverse kidney health outcomes, not only increasing the risk for the development of acute and chronic kidney diseases, but also disrupting the delivery of critical kidney health services. In particular, the delivery of dialysis services during major emergencies remains an ongoing and increasing problem, with a recognized need for improved emergency preparedness and disaster management (EP-DM) strategies to mitigate the increased risk of morbidity and mortality associated with missed dialysis treatment.

Unraveling Diabetic Kidney Disease: The Roles of Mitochondrial Dysfunction and Immunometabolism.

Mitochondria are essential for cellular energy production and are implicated in numerous diseases, including diabetic kidney disease (DKD). Current evidence indicates that mitochondrial dysfunction results in alterations in several metabolic pathways within kidney cells, thereby contributing to the progression of DKD. Furthermore, mitochondrial dysfunction can engender an inflammatory milieu, leading to the activation and recruitment of immune cells to the kidney tissue, potentially perturbing intrarenal metabolism.

Background: Predicting mortality risk in neonatal intensive care units (NICUs) is challenging due to complex, variable clinical and physiological data. Machine learning (ML) offers potential for more accurate risk stratification.

Objective: To compare the performance of various ML models in predicting NICU mortality using a team-based modeling competition.

Integrated management of concurrent traumatic penetrating brain injury and electrical injury: illustrative case.

Background: Transorbital penetrating brain injury (PBI) accompanied by electrical injury is an extremely rare presentation. This type of traumatic injury has a unique set of diagnostic and therapeutic challenges due to the potential multiple organ system involvement and severe neurological complications.

Observations: A 50-year-old male experienced a high-impact injury from a welding spike that penetrated the orbit just above the eyeball with a concurrent electrical injury; the electricity exited through the great toe.

The Impact of Sugar Conformation on the Single-Stranded DNA Selectivity of APOBEC3A and APOBEC3B Enzymes.

The APOBEC3 family of polynucleotide cytidine deaminases has diverse roles as viral restriction factors and oncogenic mutators. These enzymes convert cytidine to uridine in single-stranded (ss)DNA, inducing genomic mutations that promote drug resistance and tumor heterogeneity. Of the seven human APOBEC3 members, APOBEC3A (A3A) and APOBEC3B (A3B) are most implicated in driving pro-tumorigenic mutations.

The SWIB domain-containing DNA topoisomerase I of mediates DNA relaxation.

The obligate intracellular bacterial pathogen, (Ct), has a distinct DNA topoisomerase I (TopA) with a C-terminal domain (CTD) homologous to eukaryotic SWIB domains. Despite the lack of sequence similarity at the CTDs between TopA (CtTopA) and TopA (EcTopA), full-length CtTopA removed negative DNA supercoils and complemented the growth defect of an mutant. We demonstrated that CtTopA is less processive in DNA relaxation than EcTopA in dose-response and time course studies.

Modulation of antigen delivery and lymph node activation in nonhuman primates by saponin adjuvant saponin/monophosphoryl lipid A nanoparticle.

Saponin-based vaccine adjuvants are potent in preclinical animal models and humans, but their mechanisms of action remain poorly understood. Here, using a stabilized HIV envelope trimer immunogen, we carried out studies in nonhuman primates (NHPs) comparing the most common clinical adjuvant aluminum hydroxide (alum) with saponin/monophosphoryl lipid A nanoparticles (SMNP), an immune-stimulating complex-like adjuvant. SMNP elicited substantially stronger humoral immune responses than alum, including 7-fold higher peak antigen-specific germinal center B-cell responses, 18-fold higher autologous neutralizing antibody titers, and higher levels of antigen-specific plasma and memory B cells.

Insulin activates parasympathetic hepatic-related neurons of the paraventricular nucleus of the hypothalamus through mTOR signaling.

Integration of autonomic and metabolic regulation, including hepatic function, is a critical role played by the brain's hypothalamic region. Specifically, the paraventricular nucleus of the hypothalamus (PVN) regulates autonomic functions related to metabolism, such as hepatic glucose production. Although insulin can act directly on hepatic tissue to inhibit hepatic glucose production, recent evidence implicates central actions of insulin within PVN also regulates glucose metabolism.

GLP-1 receptor agonists and delayed gastric emptying: implications for invasive cardiac interventions and surgery.

Glucagon-like peptide-1 (GLP-1) is a hormone involved in glucose homeostasis and satiety regulation. The review highlights the importance of understanding the interplay between GLP-1 and gastric motility. This paper explores the intricate connection between GLP-1 and delayed gastric emptying, specifically gastroparesis, and its implications in the context of pulmonary aspiration during anesthesia along with the potential effects of GLP-1 medications on absorption of other medications.

Associations of plasma SMOC1 and soluble IL6RA levels with the progression from mild cognitive impairment to dementia.

Despite the central role attributed to neuroinflammation in the etiology and pathobiology of Alzheimer's disease (AD), the direct link between levels of inflammatory mediators in blood and cerebrospinal fluid (CSF) compartments, as well as their potential implications for AD diagnosis and progression, remains inconclusive. Moreover, there is debate on whether inflammation has a protective or detrimental effect on disease onset and progression. Indeed, distinct immunological mechanisms may govern protective and damaging effects at early and late stages, respectively.

The emerging role of alarmin-targeting biologics in the treatment of patients with COPD.

Topic Importance: Chronic obstructive pulmonary disease (COPD) is a complex, heterogeneous lung disease characterized by persistent airflow limitation secondary to airways and parenchymal abnormalities, and respiratory symptoms, including dyspnoea, fatigue, chronic cough, and sputum production. Cigarette smoke exposure is a major contributor to COPD although inhalation of toxic particles and other environmental and host factors can contribute to its genesis. Over time, the clinical course is frequently punctuated by exacerbations that further accelerate lung function decline and increase exacerbation risk.

Investigating the Impact of Host Factors on Vaccinia Virus Infection Through Single-Cell Analysis via Flow Cytometry.

To investigate the impact of a host factor on viral replication, conventional techniques involve analyzing viral replication within a homogeneous cell population engineered to uniformly express the host factor. In this chapter, we present a method to explore the intricate dynamics between host factors and vaccinia virus (VACV) infection using flow cytometry, which enables the rapid, multi-parametric analysis of individual cells in solution. Cultured cells are transfected to express a host factor fused with a fluorescent protein, followed by infection with a VACV encoding a different fluorescent reporter.
