Cardiovascular disease encompasses a wide group of conditions that affect the heart and blood vessels. Of these diseases, cardiomyopathies and arrhythmias specifically have been well-studied in their relationship to cardiac dyads, nanoscopic structures that connect electrical signals to muscle contraction. The proper development and positioning of dyads is essential in excitation–contraction (EC) coupling and, thus, beating of the heart. Three proteins, namely CMYA5, JPH2, and BIN1, are responsible for maintaining the dyadic cleft between the T-tubule and junctional sarcoplasmic reticulum (jSR). Various other dyadic proteins play integral roles in the primary function of the dyad—translating a propagating action potential (AP) into a myocardial contraction. Ca²⁺, a secondary messenger in this process, acts as an allosteric activator of the sarcomere, and its cytoplasmic concentration is regulated by the dyad. Loss-of-function mutations have been shown to result in cardiomyopathies and arrhythmias. Adeno-associated virus (AAV) gene therapy with dyad components can rescue dyadic dysfunction, which results in cardiomyopathies and arrhythmias. Overall, the dyad and its components serve as essential mediators of calcium homeostasis and excitation–contraction coupling in the mammalian heart and, when dysfunctional, result in significant cardiac dysfunction, arrhythmias, morbidity, and mortality.

Background/Objectives: Metabolic syndrome (Mets) risk is influenced by both parents’ preconception lifestyle, yet most interventions target individuals rather than couples. True couples-based interventions that engage both partners equally remain rare. This study aimed to assess the feasibility and adherence of a 10-week lifestyle intervention delivered to heterosexual couples in the preconception period. Methods: This was a pre-post mixed-methods study involving eight nulliparous, cohabiting couples (N = 16 participants) planning a pregnancy within three years. Couples received tailored dietary and physical activity advice via remote sessions. Qualitative data were collected through post-intervention dyadic interviews and thematically analysed to explore participants’ experiences and perspectives on feasibility and adherence. Quantitative data on anthropometry, dietary intake (serves from five food groups), and sedentary behaviour were descriptively analysed. Wilcoxon signed-rank tests were used to assess changes in paired outcomes. Results: qualitative findings highlighted shared motivation, mutual accountability, cultural barriers, and the practicality of the intervention structure. All couples completed the intervention (100% retention). Among participants who required change, improvements were observed in all eight individuals for body mass index and in five out of seven individuals for waist-to-hip ratio. Statistically significant improvements were found in BMI (p = 0.027) and grain intake (p = 0.002), while other dietary and anthropometric changes were not significant. Dietary improvements were noted in 43 out of 80 observations across vegetables, fruits, grains, protein, and dairy intake. Sedentary hours were reduced in 12 of 16 participants, though increases in physical activity intensity were limited. Conclusions: A true-couples-based lifestyle intervention is feasible and acceptable in the preconception period. The approach shows potential for improving diet and reducing sedentary behaviour. Future research with a larger sample and longer duration is recommended to assess long-term effectiveness and broader applicability. Full article

Background/Objectives: Although psychoeducation for relatives of individuals with a first episode psychosis is important for increasing understanding of psychosis, reducing relapse rates, decreasing hospitalization duration, and improving patient functionality, there is limited research on the specific experiences and needs of relatives of patients with a first episode psychosis. This study aims to explore the experiences and needs of relatives of young adults with first-episode psychosis regarding psychoeducation, with the goal of developing tailored psychoeducation (PE) that can be delivered by nurses. Methods: This qualitative study employed a descriptive, interpretative approach with a total sample of 23 participants, including semi-structured interviews (N = 16), two dyadic interviews (N = 4) and one triadic interview (N = 3). The dyadic interviews included two relatives and two patients, while the triadic interview involved two relatives and one patient. A topic list was utilized to guide the interviews. Thematic analysis was employed to analyse the data, supported by the use of ATLAS.ti. Results: During data analysis, five key themes were identified as relevant for the development of a psychoeducational program: experiences with first-episode psychosis and psychoeducation, the content of PE (what), timing (when), exchanging experiences (how) and joint PE versus separate groups (which format). Conclusions: This study highlights valuable insights and key components for an integrated psychoeducation program, focussing on the needs and experiences of relatives, for the development of the PE program. To optimize the benefits for both parties, future research should explore the potential of offering PE sessions that accommodate both individual and combined participant formats, allowing for a design tailored to the specific needs of the participants.

Background/Objectives: The association between sexual dysfunction and diabetes is well known, but few studies have investigated its prevalence in type 1 diabetes (T1D). The aim of this study was to evaluate the prevalence of sexual dysfunction in a group of women with T1D, regardless of their age, and to compare its different prevalences in women treated with different insulin regimens. Methods: The population included 77 women affected by T1D, of which 16 were on Multiple Daily Injections (MDI) and 61 on Continuous Subcutaneous Insulin Infusion (45 on Advanced Hybrid Closed Loop System with catheter and 16 on patch pump). All participants completed the Female Sexual Function Index (FSFI), a questionnaire that evaluates several aspects of sexual function. Another questionnaire that evaluated general features, diabetes-specific features and sexual-specific features was proposed to every participant. Results: The overall prevalence of female sexual dysfunction was 49.3%. A correlation was demonstrated between the prevalence of female sexual dysfunction and age; another correlation was found between the prevalence of female sexual dysfunction and dyadic status. No correlation between glycemic control and sexual dysfunction was found. Conclusions: Women with T1D presented a high prevalence of sexual dysfunction, independently from glycometabolic disease control and insulin regimens; on the other hand, a significant correlation was demonstrated with age and dyadic status. Evaluation of sexual function in women with T1D appears to be important in clinical settings independently from disease control. Full article

Background/Objectives: The association between sexual dysfunctions and diabetes is largely known, but few studies investigated its prevalence in Type 1 Diabetes (T1D). The aim of this study was to evaluate the prevalence of sexual dysfunction in a group of men with T1D regardless of their age and to compare the prevalence in men treated with different intensive insulin regimens. Methods: The study population included 68 men affected by T1D, of whom 17 were on Multiple Daily Injections (MDI) and 51 were on Continuous Subcutaneous Insulin Infusion (41 on Advanced Hybrid Closed Loop System with catheters and 10 on patch pumps). All participants completed the International Index of Erectile Function (IIEF-15), which evaluates several domains of sexual function. Another questionnaire that evaluated general features, diabetes-specific features, and sexual-specific features was proposed to every participant. Results: The overall prevalence of erectile dysfunction was 48.5%, and the overall prevalence of a severe grade of erectile dysfunction was 26.5%. Correlations were demonstrated between the prevalence of erectile dysfunction and age and between the prevalence of erectile dysfunction and dyadic status. Age and dyadic status were also correlated with lower scores in several other domains of the IIEF-15 questionnaire. Conclusions: Men with Type 1 Diabetes present a high prevalence of erectile dysfunction, independent of glycometabolic control of the disease and insulin regimens; on the contrary, a great correlation is demonstrated with age and dyadic status.

Background/Objectives: Relationship quality is closely tied to sexual health. This study compared the effects of tadalafil cream and oral tadalafil on Dyadic Adjustment Scale (DAS) subscales and assessed the influence of age on treatment outcomes. Methods: This study includes a secondary analysis of data collected during a previously published randomized controlled crossover trial, but they were not published at that time. The participants (n = 35) completed both tadalafil cream and oral tadalafil interventions in a crossover design. Dyadic Adjustment, including DAS subscales, was assessed at baseline and after each intervention. Improvements across all DAS subscales were greater in the tadalafil cream group compared to the oral tadalafil group. Statistically significant differences were observed for Affective Expression (5.45, 95% CI: 0.22–10.67, p = 0.041) in the multivariate model. Notable gains were observed in Affective Expression and Dyadic Cohesion for the cream route. Within-group analysis showed statistically significant improvements in Affective Expression for both treatments and in Dyadic Cohesion for the cream route. The results show that younger participants benefited more from treatment, particularly in Affective Expression, Consensus subscales, and overall for Dyadic Adjustment. Conclusion: This study provides evidence that tadalafil intervention had a favorable impact on relationship dynamics, particularly in Affective Expression and Dyadic Cohesion. Full article

Black/African American individuals experience high rates of posttraumatic stress disorder (PTSD), which is frequently chronic and undertreated in this population. Intimate relationships are a salient resource for Black/African American adults’ psychological well-being. To help advance health equity, this study serves as an initial, proof-of-concept investigation of patient outcomes among Black/African American adults who received a disorder-specific couple therapy for PTSD. Participants were a subsample of seven Black/African American adults (mean age = 40.56 years, SD = 10.18; 85.7% male) who participated in an uncontrolled trial of an abbreviated, intensive, multi-couple group version of cognitive-behavioral conjoint therapy for PTSD with 24 military dyads. Treatment was delivered over 2 days in a weekend retreat format. Assessments were administered at baseline, 1 month post-retreat, and 3 months post-retreat. There were large and significant decreases in patients’ PTSD symptoms based on clinicians’ and patients’ ratings (ds −1.37 and −1.36, respectively) by the 3-month follow-up relative to baseline. There were also large and significant decreases in patients’ depressive, anxiety, and anger symptoms (ds −1.39 to −1.93) and a large, marginally significant decrease in patients’ insomnia (d = −0.85; p = 0.083). Patients reported a medium, non-significant increase in relationship satisfaction (d = 0.68; p = 0.146) and a large, marginally significant increase in joint dyadic coping (d = 0.90; p = 0.069). Findings offer preliminary evidence that treating PTSD within a couple context is a relevant strategy to reduce PTSD and comorbid symptoms among partnered Black/African American adults and a promising approach to enhance relationships.

Background: Parent–child interactions during mealtime significantly influence social, emotional, and cognitive development in early childhood. Increasing parental use of digital technology has been linked to disruptions in these interactions, a phenomenon termed “technoference,” which is associated with relational conflicts and psychosocial difficulties in children. Feeding interactions are particularly important for fostering attachment and emotional regulation, making them a vital area for studying technology’s effects on parent–child dynamics. Aims: This study aimed to evaluate the impact of parental digital technology use during mealtime on the quality of feeding interactions and child dysregulation symptoms. Two groups were compared: mothers who used devices during mealtime (Technology Group, TG) and mothers who did not (Non-Technology Group, NTG). Methods: Participants included mother–child dyads (TG) and a matched control group (NTG) (Ntot = 174), selected from a broader research project. Mother–child pairs were observed during a 20 min midday meal using the validated Italian Scala di Valutazione dell’Interazione Alimentare (SVIA). The emotional and behavioral functioning of children was assessed with the Child Behavior Checklist (CBCL). Statistical analyses included ANOVAs and post hoc tests. Results: The TG group demonstrated significantly higher scores on all SVIA subscales, indicating greater parental affective challenges, conflict, food refusal behaviors, and dyadic distress. Additionally, children in the TG group exhibited more internalizing and externalizing problems, including dysregulation symptoms on the CBCL, compared to the NTG group. Conclusions: Parental technology use during mealtime negatively affects parent–child feeding interactions and increases dysregulation in children. These findings highlight the need for mindful parenting strategies to limit digital distractions and foster healthier family dynamics. Full article

This hyperscanning study explores the central (hemodynamic) and peripheral (autonomic) markers of persuasion within a shared decision-making process. Decision-making was examined through a task where two decision-makers assumed the role of Persuader (P-der) and Persuaded (P-ded), with the P-der aiming to increase group decision orientation in the P-ded. Data were collected from 14 dyads using functional near-infrared spectroscopy to measure prefrontal cortex (PFC) hemodynamic activity and collection and recording of autonomic indices including heart rate (HR) and HR variability (HRV). The analysis focused on two phases: Phase 1, where the P-der presented the scenario and enacted their persuasive strategy, and Phase 2, characterized by the P-ded’s response. The results revealed significant effects on the dissimilarity indices at the dyadic level. Compared with Phase 1, Phase 2 included higher oxygenated hemoglobin dissimilarity in the PFC, indicating greater inter-dyadic divergence during the P-ded’s response. HR dissimilarity increased when the P-ded spoke, suggesting disrupted synergy, while HRV dissimilarity was higher when the P-der spoke, potentially reflecting differences in stress regulation. These findings suggest that neurophysiological coherence varies based on persuasion phases within shared decision-making, with P-ded introducing greater dissonance in dyads synergy. Compared with single-subject approaches, dyadic analyses offer a more accurate understanding of the interpersonal nature of persuasion dynamics during decision-making. Full article

In this paper, we detail the technical development of a conversation design that is sensitive to group dynamics and adaptable, taking into account the subtleties of linguistic variations between dyadic (i.e., one human and one agent) and group interactions in human–robot interaction (HRI) using the German language as a case study. The paper details the implementation of robust person and group detection with YOLOv5m and the expansion of knowledge databases using large language models (LLMs) to create adaptive multi-party interactions (MPIs) (i.e., group–robot interactions (GRIs)). We describe the use of LLMs to generate training data for socially interactive agents including social robots, as well as a self-developed synthesis tool, knowledge expander, to accurately map the diverse needs of different users in public spaces. We also outline the integration of a LLM as a fallback for open-ended questions not covered by our knowledge database, ensuring it can effectively respond to both individuals and groups within the MPI framework.

Objective: This study aimed to assess the dyadic dynamics of benefit finding, stigma, and suicide risk on the depression severity of individuals with schizophrenia and their caregivers. Methods: We prospectively recruited a total of 72 individuals with schizophrenia and 72 caregivers of individuals with schizophrenia from a medical center in Taiwan between August 2022 and July 2023. Patients with schizophrenia and their caregivers were assessed using the Taiwanese Depression Questionnaire, Benefit Finding Scale, Explanatory Model Interview Catalogue, Suicide Assessment Scale, and Mini International Neuropsychiatric Interview. Results: The most prevalent psychiatric diagnoses in the caregivers were depressive disorders (29.2%). Using structural equation modeling, we found that patients’ suicidal risk (β = 0.45, p < 0.001) may contribute to the severity of depression in individuals with schizophrenia. We also found that caregivers’ BF degree (β = −0.25, p < 0.01) and suicidal risk (β = 0.64, p < 0.001) may contribute to the severity of depression in the caregivers of individuals with schizophrenia. Furthermore, we found that caregivers’ suicidal risk (β = 0.28, p < 0.05) and caregivers’ stigma (β = −0.31, p < 0.01) level may contribute to the severity of depression in individuals with schizophrenia. Discussion: Clinicians should actively manage caregivers’ stigma and provide positive reinforcement for caregivers’ BF, as this may help reduce depression in both caregivers and individuals with schizophrenia. Additionally, assessing suicide risk in both groups is essential for preventing suicides among individuals with schizophrenia and caregivers alike. Full article

Background/Objectives: The Prostate Cancer Patient Empowerment Program (PC-PEP) is a 6-month, home-based intervention aimed at enhancing mental health in men undergoing curative prostate cancer treatment. This exploratory secondary analysis evaluates PC-PEP’s impact on relationship satisfaction, quality of life, and support group attendance among partnered participants. Methods: In a crossover randomized clinical trial ClinicalTrials.gov identifier: NCT03660085) of 128 men aged 50–82 scheduled for curative prostate cancer surgery or radiotherapy, 119 participants in relationships were included. Of these, 59 received the 6-month PC-PEP intervention, while 60 were randomized to a waitlist-control arm, receiving standard care for 6 months before starting PC-PEP. The intervention included daily emails with video instructions on mental and physical health, diet, social support, fitness, stress reduction, and intimacy. Outcomes were assessed using the Dyadic Adjustment Scale (DAS) and the Functional Assessment of Cancer Therapy–Prostate (FACT-P). Results: While relationship satisfaction remained stable, a significant improvement in emotional well-being was observed at 12 months in participants undergoing radiation therapy (p = 0.045). The PC-PEP intervention also led to significantly higher support group attendance at both 6 months (p = 0.001) and 12 months (p = 0.003), emphasizing its role in fostering social support and community engagement. Conclusions: The PC-PEP program effectively maintains relationship satisfaction and enhances emotional well-being, particularly in patients with fewer physical side effects. Its design promotes comprehensive care by integrating physical, psychological, and social support, making it a valuable resource for improving the quality of life in prostate cancer patients and potentially applicable to other cancer types.

Compelling evidence supports the foundational importance of early self-regulation (SR). It also supports parents in the home environment as having the foremost influence on early development. Yet, prevailing approaches to support early SR growth have tended to leverage early education and clinical settings. Partners in Play (PiP) was developed as a sustainable approach for parents to learn how and when to support children through experiences of self-regulation challenges in the home learning environment. This study reports the first randomised control trial evaluation of the PiP program, with 21 parent–child dyads (consisting of twelve girl–mother dyads, eight boy–mother dyads, and one boy–father dyad; mean child age = 4.12 years, SD = 0.65). Dyads were randomised to a PiP intervention group (n = 10), which entailed four online parent information sessions and four out-of-home guided practice dyadic play sessions across 8 weeks, or an active control group (n = 11). The primary outcome was parent autonomy support, and the secondary outcome was child SR. Results indicated a significant increase in parents’ use of autonomy support and a non-significant but moderate-sized effect on child SR. This innovative proof-of-concept program and evaluation provides a roadmap for effecting change in parental support during children’s play, to the prospective benefit of important abilities such as child SR. Analyses show promise for a parent-based model toward parent behaviour change and child SR improvement. Full article

The phenomenon of empathy is an intersubjective process of feeling and a particular form of intentionality. Moral empathy refers to a type of empathy that can trigger moral action, with the embodied intersubjectivity laying the foundation for its emergence. This paper attempts to propose a comprehensive theoretical model of moral empathy from the perspective of intersubjective phenomenology, which includes the following. (1) The moral dimension of perceptual empathy: at the subpersonal, unconscious, and perceptual–motor level, embodied empathic practices are essential for the formation of moral consciousness and the emergence of moral empathy. (2) The moral dimension of situational empathy: following the development of shared attention mechanisms, children can direct towards the intentional objects of others through embodied situational cues to perceive the psychological state of others and generate the moral empathy of “ought”, leading to dyadic morality that promotes cooperative behavior. (3) The moral dimension of narrative empathy: the narrative practices of moral empathy refer to the processes by which children could perceive and understand the moral situation of characters within an embodied narrative structure, subsequently generate prosocial motives such as empathic concern, and then accept the “objective” moral norms of the group consciousness embedded in the narrative.

Aim: The aim of this study is to explore and compare experiences of pain management strategies for children with CP from the perspectives of children themselves and their parents. Methods: A secondary inductive analysis of previously collected qualitative data was performed. Fourteen children with CP and one parent of each child were interviewed separately about the management of the child’s pain. A dyadic data analysis was used to compare parents’ and children’s perspectives. Findings: The main thematic categories of pain management identified were self-care, psychological strategies, physical interventions and professional treatment. Experiences described by the child and parent differed within all participating dyads but to different degrees. On a group level, children described more use of psychological strategies than parents did. Parents described more professional treatment strategies. Conclusions: Parents and children described different experiences of pain management strategies, and both perspectives are needed to understand the child’s situation. Full article
