Density functional theory for fractional charge: Locality, size consistency, and exchange-correlation.

J Chem Phys

December 2024

Department of Chemistry and Center for Computational and Data Sciences, Middle Tennessee State University, 1301 Main St., Murfreesboro, Tennessee 37130, USA.

We show that the exact universal density functional of integer electronic charge leads to an extension to fractional charge in an asymptotic sense when it is applied to a system made of asymptotically separated densities. The extended functional is asymptotically local and is said to be i-local. The concept of i-locality is also applicable to nuclear external potentials, and a natural association exists between the localities of a density and a set of nuclei.

Introduction: Coronary artery disease (CAD) and peripheral artery disease (PAD) increase the risks of cardiovascular events and death. Digital health technologies are rapidly expanding to improve healthcare quality and access. The Care4Today Connect (C4T CAD-PAD) mobile application is designed to help patients with CAD and/or PAD improve medication adherence, learn about their disease, make lifestyle modifications, and enhance healthcare provider (HCP) connection via an HCP-facing portal.

A search is reported for charge-parity violation in decays, using data collected in proton-proton collisions at recorded by the CMS experiment in 2018. The analysis uses a dedicated data set that corresponds to an integrated luminosity of 41.6 , which consists of about 10 billion events containing a pair of b hadrons, nearly all of which decay to charm hadrons.

Purpose: Oral adjuvant endocrine therapy (AET) reduces the risk of cancer recurrence and death for women with hormone receptor-positive (HR+) breast cancer. Because of adverse symptoms and socioecologic barriers, AET adherence rates are low. We conducted post hoc analyses of a randomized trial of a remote symptom and adherence monitoring app to evaluate characteristics associated with higher app use, satisfaction, and how app use was associated with AET adherence.

Genetic variants associated with sepsis-associated acute kidney injury.

PLoS One

December 2024

Department of Anesthesiology, Michigan Medicine, Ann Arbor, Michigan, United States of America.

Background: Kidney dysfunction is a common complication in septic patients. Studies have identified numerous risk factors for sepsis-associated acute kidney injury (S-AKI), yet there is wide variability in the incidence even among patients with similar risk factors, suggesting the presence of additional uncharacterized risk factors, including genetic differences. The expansion of biobanks, advances in genotyping, and standardized diagnostic criteria have enabled large-scale, hypothesis-generating studies into the genetic mechanisms underlying S-AKI.

Untargeted metabolomics and lipidomics in COVID-19 patient plasma reveals disease severity biomarkers.

Metabolomics

December 2024

Division of Systems Biology, National Center for Toxicological Research, United States Food and Drug Administration, 3900 NCTR Road, Jefferson, AR, 72079, USA.

Introduction: Coronavirus disease 2019 (COVID-19) has widely varying clinical severity. Currently, no single marker or panel of markers is considered standard of care for prediction of COVID-19 disease progression. The goal of this study is to gain mechanistic insights at the molecular level and to discover predictive biomarkers of severity of infection and outcomes among COVID-19 patients.

Evolution is an important part of biology education, but many college biology students do not accept important components of evolution, like the evolution of humans. Practices that reduce perceived conflict between religion and evolution have been proposed to increase student evolution acceptance. This study investigates college student experiences of conflict reducing practices in evolution education and how these experiences are related to their gains in acceptance of human evolution during evolution instruction.

  • - The HEALing Communities Study (HCS) aimed to reduce opioid overdose deaths in 67 affected communities by implementing health campaigns focused on opioid use disorder (OUD), overdose prevention, and stigma reduction, developed with community input.
  • - Surveys conducted via Facebook/Instagram indicated that participants in HCS communities experienced reduced stigma related to OUD and improved beliefs about the efficacy of naloxone, though recognition of campaign messages was not significantly different from control communities.
  • - The study suggests a connection between recognizing campaign messages and achieving positive outcomes, but it also raises concerns about the effectiveness of traditional evaluation methods for social media health campaigns.

  • The study explores attitudes of living kidney donor candidates of African ancestry toward using the Gia chatbot for Apolipoprotein L1 (APOL1) genetic testing during the donor evaluation process.
  • Focus groups with 54 participants revealed that most supported the use of the chatbot prior to clinic visits and expressed interest in APOL1 testing after utilizing the technology.
  • However, concerns about testing costs and individual preferences for chatbot usage in healthcare settings emerged as potential barriers to widespread adoption.

Department of Obstetrics, Gynecology, Gynecologic Oncology and Senology, Bethesda Hospital Duisburg, Duisburg, Germany.

Diaphragmatic endometriosis is one of the most common localization of extra-pelvic endometriosis and may cause debilitating symptoms such as cyclic shoulder pain, right upper abdominal pain, and right-sided chest pain. Diaphragmatic endometriosis may also be asymptomatic. The exact mechanisms by which diaphragmatic endometriosis originates are unknown.

Background: Antisocial behaviors occur in up to 91% of individuals with behavioral variant frontotemporal dementia (bvFTD). Prior work has shown that antisocial behaviors can be differentiated into aggressive and nonaggressive rule-breaking behavioral subtypes. Socioemotional dysfunction is common in bvFTD and unique compared to other types of dementia.

  • Rheumatic heart disease (RHD) poses significant health issues, especially in low- and middle-income countries, but data on its impact in wealthier regions like the USA and EU is limited.
  • A study comparing the epidemiology of RHD in the USA and EU revealed that the USA has a higher prevalence (123.4/100,000) but a slower decreasing trend compared to the EU (49.7/100,000), with key trends driven by states like Florida and Tennessee.
  • Both regions show a gender disparity with higher cases in females, and the findings highlight the need for tailored strategies to tackle RHD effectively based on regional data.

Pleiotropy increases with gene age in six model multicellular eukaryotes.

bioRxiv

November 2024

Department of Biological Sciences, Vanderbilt University, Nashville TN, 37235.

Fundamental traits of genes, including function, length and GC content, all vary with gene age. Pleiotropy, where a single gene affects multiple traits, arises through selection for novel traits and is expected to be removed from the genome through subfunctionalization following duplication events. It is unclear, however, how these opposing forces shape the prevalence of pleiotropy through time.

  • - The study investigates the impact of social vulnerability on clinical outcomes for hospitalized influenza patients, analyzing data from over 57,000 cases between the 2014-2015 and 2018-2019 influenza seasons across 13 states.
  • - It aims to understand how social vulnerability correlates with severe outcomes like ICU admission, use of advanced respiratory support, and 30-day mortality, while also examining patterns of vaccine and antiviral use based on social vulnerability levels.
  • - Findings reveal that patients from areas with high social vulnerability experience worse outcomes, such as higher rates of needing invasive ventilation support compared to those from less vulnerable areas.

  • The Implicit Prosody Hypothesis (IPH) suggests that people create internal vocal patterns while reading silently, similar to those used in spoken language.
  • The study used EEG to analyze brain responses as participants read sequences of words with different stress patterns, revealing that unexpected stress in words triggered stronger brain reactions.
  • Results indicated that various brain wave activities correlate with rhythmic expectations in language, supporting the idea that the same neural networks are involved in processing both spoken and silently read language.
