Quantifying the Deficits of Body Water and Monovalent Cations in Hyperglycemic Emergencies.

J Clin Med

December 2024

Research Service, Department of Medicine, Raymond G. Murphy Veterans Affairs Medical Center, University of New Mexico School of Medicine, Albuquerque, NM 87108, USA.

Hyperglycemic emergencies cause significant losses of body water, sodium, and potassium. This report presents a method for computing the actual losses of water and monovalent cations in these emergencies. We developed formulas for computing the losses of water and monovalent cations as a function of the presenting serum sodium and glucose levels, the sum of the concentrations of sodium plus potassium in the lost fluids, and body water at the time of hyperglycemia presentation as measured by bioimpedance or in the initial euglycemic state as estimated by anthropometric formulas.

EM-AUC: A Novel Algorithm for Evaluating Anomaly Based Network Intrusion Detection Systems.

Sensors (Basel)

December 2024

Department of Engineering Management and Systems Engineering, George Washington University, Washington, DC 20052, USA.

Effective network intrusion detection using anomaly scores from unsupervised machine learning models depends on the performance of the models. Although unsupervised models do not require labels during the training and testing phases, the assessment of their performance metrics during the evaluation phase still requires comparing anomaly scores against labels. In real-world scenarios, the absence of labels in massive network datasets makes it infeasible to calculate performance metrics.

Immunotherapy, particularly that based on blocking checkpoint proteins in many tumors, including melanoma, Merkel cell carcinoma, non-small cell lung cancer (NSCLC), triple-negative breast (TNB cancer), renal cancer, and gastrointestinal and endometrial neoplasms, is a therapeutic alternative to chemotherapy. Immune checkpoint inhibitor (ICI)-based therapies have the potential to target different pathways leading to the destruction of cancer cells. Although ICIs are an effective treatment strategy for patients with highly immune-infiltrated cancers, the development of different adverse effects including cutaneous adverse effects during and after the treatment with ICIs is common.

Clinical features associated with self-reported food insecurity in people with cystic fibrosis.

J Cyst Fibros

January 2025

Division of Pulmonary and Sleep Medicine, Children's Hospital of Philadelphia, Philadelphia, PA, USA; University of Pennsylvania Perelman School of Medicine, Philadelphia, PA, USA.

Background: Food insecurity (FI) is more prevalent in people with cystic fibrosis (PwCF) than the reported national prevalence, but there are limited data on the relationship between FI and health outcomes in PwCF. The objective of this study was to analyze the relationship between FI in PwCF and pulmonary and nutritional status.

Methods: We leveraged an electronic cross-sectional survey that ascertained FI status and gave participants the option to link their survey data to their records in the Cystic Fibrosis Foundation Patient Registry (CFFPR).

In literate adults, an area along the left posterior fusiform gyrus that is often referred to as the "visual word form area" (VWFA) responds particularly strongly to written characters compared to other visually similar stimuli. Theoretical accounts differ in whether they attribute the strong left-lateralization of the VWFA to a left-hemisphere bias towards visual features used in script, to competition of visual word form processing with that of other visual stimuli processed in the same general cortical territory (especially faces), or to the well-established left-lateralization of the language system.Here we used functional magnetic resonance imaging to test the last hypothesis by investigating lateralization of the VWFA in participants (male and female) who have right-hemisphere language due to a large left-hemisphere perinatal stroke.

Expert Rater Agreement for Symptoms and Diagnosis of Bipolar Disorder in Youth.

Child Psychiatry Hum Dev

January 2025

Department of Psychiatry and Behavioral Health, Stony Brook University, 101 Nicolls Road, Stony Brook, NY, USA.

The diagnosis of bipolar disorder (BD) in young children has been a topic of debate, in part owing to varied interpretation of manic-like symptoms. We examined how expert academic clinicians participating in the pediatric bipolar biobank varied in their interpretation and application of Diagnostic and Statistical Manual of Mental Disorders (DSM) criteria and diagnoses. Study co-investigators reviewed 12 standardized narratives and for each marked a visual analog scale with their confidence in the presence of manic episodes and criteria.

Paleoneurology reconstructs the evolutionary history of nervous systems through direct observations from the fossil record and comparative data from extant species. Although this approach can provide direct evidence of phylogenetic links among species, it is constrained by the availability and quality of data that can be gleaned from the fossil record. Here, we sought to translate brain component relationships in a sample of extant Carnivora to make inferences about brain structure in fossil species.
