A series of Ru(II)-acetylide complexes (, , and ) with alkynyl-functionalized borondipyrromethene (BODIPY) conjugates were designed by varying the position of the linker that connects the BODIPY unit to the Ru(II) metal center through acetylide linkage at either the 2-() and 2,6-() or the -phenyl () position of the BODIPY scaffold. The Ru(II) organometallic complexes were characterized by various spectroscopic methods, including nuclear magnetic resonance (NMR) spectroscopy, infrared (IR) spectroscopy, CHN, and high-resolution mass spectrometry (HRMS) analyses. The Ru(II)-BODIPY conjugates exhibit fascinating electrochemical and photophysical properties. All BODIPY-Ru(II) complexes exhibit strong absorption (ε = 29,000-72,000 M cm) in the visible region (λ = 502-709 nm). Fluorescence is almost quenched for and , whereas shows the residual fluorescence of the corresponding BODIPY core at 517 nm. The application of the BODIPY-Ru(II) dyads as nonporphyrin-based triplet photosensitizers was explored by a method involving the singlet oxygen (O)-mediated photo-oxidation of diphenylisobenzofuran. Effective π-conjugation between the BODIPY chromophore and Ru(II) center in the case of and was found to be necessary to improve intersystem crossing (ISC) and hence the O-sensitizing ability. In addition, electrochemical studies indicate electronic interplay between the metal center and the redox-active BODIPY in the BODIPY-Ru(II) dyads.

Dyadic effects of illness perception and maladaptive cognitive-emotional regulation strategies on the fear of cancer recurrence in breast cancer patients and spouses: an actor-partner interdependence mediation model.
BMC Psychiatry
January 2025
The First Hospital of Jilin University, Changchun, Jilin Province, China.
Purpose: Breast cancer, as a stressful event, profoundly impacts the entire family, especially patients and their spouses. This study used a dyadic analysis approach to explore the dyadic effects of illness perception on the fear of cancer recurrence (FCR) and whether maladaptive cognitive-emotional regulation strategies acted as a mediator in breast cancer patient-spouse dyads.
Methods: This was a cross-sectional study, and 202 dyads of breast cancer patients and their spouses were enrolled.

Background: The accuracy of low birth weight (LBW) and small for gestational age (SGA) in administrative healthcare records is crucial for perinatal studies but has few validity studies.
Methods: Using 1999-2010 MAX linked to birth certificates (BC), we identified mother-infant dyads (≥30 days enrollment after delivery, with valid gestational age (GA) and birth weight (BW)). LBW and SGA were identified based on ICD-9-CM codes.

Background: Alzheimer disease and related dementias (ADRDs) are increasingly common progressive conditions that have a substantial impact on individuals and their primary care partners-together described as a dyad. The stressors experienced by dyad members at around the time of ADRD diagnosis commonly produce clinically elevated emotional distress (ie, depression and anxiety symptoms), which can become chronic and negatively impact health, relationships, and the overall quality of life. Dyads commonly report unmet needs for early support to address these challenges early after diagnosis.

Early mother-infant interaction is believed to have a significant impact on the social, cognitive, and emotional development of children. These interactions are not only influenced by child and contextual factors but also by the mother's personality traits and strain. In this study, we investigated the relation between maternal factors such as personality, depressive symptoms, or experiencing of emotions, and (i) children's early cognitive development and (ii) interaction patterns in a sample of 116 mother-child dyads (mean child age = 18.

Background And Objectives: Some Minnesota clinicians perceive that the incidence of prophylactic vitamin K refusal is increasing, yet the actual incidence and which populations are most likely to refuse is unknown. Our objective is to identify the incidence of vitamin K refusal and to characterize the maternal-newborn dyads with increased refusal rates.
Methods: This retrospective multi-institution study analyzed vitamin K refusal in newborns born from 2015 to 2019.
