A new nucleation theory is presented. This theory is based on the assumption that a critical nucleus of the new phase can be regarded as an activated complex that passes through the top of the energy barrier. In the framework of the proposed approach, an equation in a general form for the nucleation rate is obtained. This equation is used to obtain the calculated data in the case of homogeneous nucleation at the vapor-liquid, liquid-vapor, and liquid-solid phase transitions. A comparison of the calculated data with the available experimental data as well as with the calculated data obtained in the framework of the classical nucleation theory is carried out. From a comparison between the calculated data obtained in the framework of the presented theory and the experimental data for the supercooled water-ice phase transition, the dependence on temperature of the surface tension coefficient between supercooled water and ice is determined.

Impact of a Virtual Care Navigation Service on Member-Reported Outcomes Among Lesbian, Gay, Bisexual, Transgender, and Queer Populations: Case Study.
JMIR Form Res
January 2025
School of Nursing, University of Pennsylvania, 418 Curie Blvd, Philadelphia, PA, 19104, United States, 1 8123695216.
Background: While the significance of care navigation in facilitating access to health care within the lesbian, gay, bisexual, transgender, queer, and other (LGBTQ+) communities has been acknowledged, there is limited research examining how care navigation influences an individual's ability to understand and access the care they need in real-world settings. By analyzing private sector data, we can bridge the gap between theoretical research findings and practical applications, ultimately informing both business strategies and public policy with evidence grounded in real-world efficacy.
Objective: The objective of this study was to evaluate the impact of specialized virtual care navigation services on LGBTQ+ individuals' ability to comprehend and access necessary care within a national cohort of commercially insured members.
Testing the mediating mechanism of alcohol use on the association between retirement and depressive symptoms in the United States using generalized mixed effect models.
Aging Ment Health
January 2025
School of Social Work, Simmons University, Boston, MA, USA.
Objectives: Both alcohol use and the prevalence of depression-depressive disorders, among older adults have increased over the past several decades and have been associated with increased morbidity and mortality. To our knowledge, the interactions between retirement, depression, and alcohol use have not yet been examined. This study aims to longitudinally explore the mediating role of alcohol use on the association between retirement and depressive symptoms in the United States, comparing individuals who are retired and not retired, while also exploring individuals who transitioned into and out of retirement at different times.

Department of Neurology, Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology, Wuhan, China.
Background: White matter hyperintensities (WMH) are prominent neuroimaging markers of cerebral small vessel disease (CSVD) linked to cognitive decline. Nevertheless, the pathophysiological mechanisms underlying WMH remain unclear.
Objective: This study aimed to assess the structural decoupling index (SDI) as a novel metric for quantifying the brain's hierarchical organization associated with WMH in cognitively normal older adults
Methods: We analyzed data from 112 cognitively normal individuals with varying WMH burdens (43 high WMH burden and 69 low WMH burden).
Background: Serum uric acid (SUA) was a predictor of cognitive function. The association of SUA/serum creatinine ratio (Scr), which represents renal function-normalized SUA and cognitive function is unknown.
Objective: This study investigated the association of the SUA/Scr with cognitive function and the potential mediation effect of inflammation in the above relationship.
A prospective study to evaluate high dose daptomycin pharmacokinetics and pharmacodynamics in spp. infective endocarditis.
Ther Adv Infect Dis

Clinica di Malattie Infettive, Fondazione IRCCS Policlinico San Matteo, Pavia 27100, Italy.
Background: Daptomycin pharmacokinetics and pharmacodynamics data relative to higher doses in patients are necessary for clinical practice.
Objectives: A monocentric, prospective study that enrolled patients with a diagnosis of spp. infective endocarditis treated with daptomycin according to clinical practice, to evaluate the pharmacokinetics/pharmacodynamics of different daptomycin daily doses (group A: 8-10 and group B: 11-12 mg/kg).
