Refinement of Atomic Polarizabilities for a Polarizable Gaussian Multipole Force Field with Simultaneous Considerations of Both Molecular Polarizability Tensors and In-Solution Electrostatic Potentials.

J Chem Inf Model

January 2025

Departments of Molecular Biology and Biochemistry, Chemical and Biomolecular Engineering, Materials Science and Engineering, and Biomedical Engineering, University of California, Irvine, Irvine, California 92697, United States.

Atomic polarizabilities are considered to be fundamental parameters in polarizable molecular mechanical force fields that play pivotal roles in determining model transferability across different electrostatic environments. In an earlier work, the atomic polarizabilities were obtained by fitting them to the B3LYP/aug-cc-pvtz molecular polarizability tensors of mainly small molecules. Taking advantage of the recent PCMRESPPOL method, we refine the atomic polarizabilities for condensed-phase simulations using a polarizable Gaussian Multipole (pGM) force field.

More than 50% of families with suspected rare monogenic diseases remain unsolved after whole-genome analysis by short-read sequencing (SRS). Long-read sequencing (LRS) could help bridge this diagnostic gap by capturing variants inaccessible to SRS, facilitating long-range mapping and phasing and providing haplotype-resolved methylation profiling. To evaluate LRS's additional diagnostic yield, we sequenced a rare-disease cohort of 98 samples from 41 families, using nanopore sequencing, achieving per sample ∼36× average coverage and 32-kb read N50 from a single flow cell.

Some CLL patients who develop progressive disease (PD) during treatment with covalent Bruton tyrosine kinase inhibitors (cBTKi) acquire pathway resistance mutations in BTK or PLCG2. Here, we report gene mutation data from paired baseline and PD peripheral blood samples from 52 patients (zanubrutinib, n=24; ibrutinib, n=28) who, at an early median follow-up time of 25.7 months, progressed on zanubrutinib or ibrutinib treatment in the ALPINE trial (NCT03734016).

Delirium Management Quality Improvement Project to Improve Awareness and Screening in a Medical ICU.

Nurs Rep

December 2024

Division of Pulmonary, Critical Care and Sleep Medicine, UC San Diego Health, La Jolla, CA 92093, USA.

Although delirium is common during critical illness, standard-of-care detection and prevention practices in real-world intensive care unit (ICU) settings remain inconsistent, often due to a lack of provider education. Despite availability for over 20 years of validated delirium screening tools such as the Confusion Assessment Method in the ICU (CAM-ICU), feasible and rigorous educational efforts continue to be needed to address persistent delirium standard-of-care practice gaps. Spanning an 8-month quality improvement project period, our single-ICU interdisciplinary effort involved delivery of CAM-ICU pocket cards to bedside nurses, and lectures by experienced champions that included a live delirium detection demonstration using the CAM-ICU, and a comprehensive discussion of evidence-based delirium prevention strategies (e.

Background: Vertical HIV-1 transmission despite antiretroviral therapy may be mitigated by use of long-acting, broadly neutralizing, monoclonal antibodies (bNAb) such as VRC07523LS. The present study was designed to determine the safety and pharmacokinetics of VRC07523LS.

Methods: VRC07523LS, 80 mg/dose, was administered subcutaneously after birth to non-breastfed (Cohort 1; N=11, enrolled in USA) and breastfed (Cohort 2; N=11, enrolled in South Africa and Zimbabwe) infants exposed to HIV-1.

Deep learning model to identify and validate hypotension endotypes in surgical and critically ill patients.

Br J Anaesth

January 2025

Department of Anesthesiology, Center of Anesthesiology and Intensive Care Medicine, University Medical Center Hamburg-Eppendorf, Hamburg, Germany; Outcomes Research Consortium, Cleveland, OH, USA. Electronic address:

Background: Hypotension is associated with organ injury and death in surgical and critically ill patients. In clinical practice, treating hypotension remains challenging because it can be caused by various underlying haemodynamic alterations. We aimed to identify and independently validate endotypes of hypotension in big datasets of surgical and critically ill patients using unsupervised deep learning.

Patients with relapsed/refractory (R/R) diffuse large B-cell lymphoma (DLBCL) progressing after chimeric antigen receptor T-cell therapy (CAR T) have dismal outcomes. The prespecified post-CAR T expansion cohort of the ELM-1 study investigated the efficacy and safety of odronextamab, a CD20×CD3 bispecific antibody, in patients with disease progression after CAR T. Sixty patients received IV odronextamab weekly for 4 cycles followed by maintenance until progression.

This randomized phase III trial aimed to determine whether treatment with cisplatin and volume-directed radiation followed by carboplatin and paclitaxel for four cycles (chemoradiotherapy [C-RT]) increased recurrence-free survival (RFS) and overall survival (OS) when compared with carboplatin and paclitaxel for six cycles (chemotherapy [CT]) in locally advanced endometrial cancer (UC). Previously reported results showed that C-RT did not improve RFS compared with CT. Here we report the final OS analysis.

Cranial radiation therapy (RT) for brain cancers is often associated with the development of radiation-induced cognitive dysfunction (RICD). RICD significantly impacts the quality of life for cancer survivors, highlighting an unmet medical need. Previous human studies revealed a marked reduction in plasma brain-derived neurotrophic factor (BDNF) post-chronic chemotherapy, linking this decline to a substantial cognitive dysfunction among cancer survivors.

Background And Objectives: Nicotinamide is a coenzyme involved in cellular oxidation-reduction reactions that can inhibit Class III histone deacetylases (HDACs) or sirtuins. HDAC inhibition can affect numerous therapeutic pathways, including tau phosphorylation. We tested the hypothesis that nicotinamide treatment could reduce tau phosphorylation in early Alzheimer disease (AD).

Introduction: Coronavirus 2019 (COVID-19) has had a devastating impact on mental health and access to addiction treatment in the United States, including in California, which resulted in the highest rates of emergency department visits (ED) for opioid poisoning in 2020. As California slowly returns to pre-pandemic normalcy, it remains uncertain whether the rates of opioid-related events have slowed down over time. We hypothesized that the number of opioid-related ED visits were exacerbated after the period of the COVID-19 pandemic and continue at a high rate in the present.

Sergievsky Center, Taub Institute, Department of Neurology, Vagelos College of Physicians and Surgeons, Columbia University, New York, NY, USA; Department of Epidemiology, Mailman School of Public Health, Columbia University, New York, NY, USA. Electronic address:

Article Synopsis
  • - Individuals with Down syndrome (DS) face a high risk of developing Alzheimer's disease (AD), but about 20% do not show dementia symptoms until later in life, potentially due to the presence of mosaicism, which can reduce gene expression from chromosome 21.
  • - Researchers analyzed data from two major studies (ABC-DS and a legacy study) that included neuropsychological assessments and biomarkers to determine the prevalence and impact of mosaicism, finding it in less than 10% of participants.
  • - Those with mosaicism exhibited lower levels of AD-related biomarkers and a slower decline in cognitive scores compared to individuals with full trisomy, indicating a potential protective effect against dementia, though more research is needed to fully understand these findings.
