- Abstract
Aims: Lack of consensus on wellness has led to a vast number of different conceptualisations, which hinder international efforts to monitor individual-level wellness and social progress comparably. This study aimed to aid in the harmonisation of the concept by contributing to the scarce research on laypeople's views on wellness. The study investigates whether the importance of different areas of wellness varies depending on age, gender, education or socio-economic position. Furthermore, considering that wellness models are often constructed by expert panels, this study aimed to shed light on how experts' and laypeople's views on wellness vary. Methods: Altogether, 1152 laypeople and 23 Finnish experts rated the importance of 61 systematic review-based wellness domains. Each domain received an ordinal number, which, together with the Mann–Whitney U -test or Kruskal–Wallis test, was used to examine the differences between the groups. Results: Thirteen wellness domains were found at the top of the lists, regardless of whether the results were analysed based on gender, age, education or socio-economic position. When looking at the priority order of different domains, we were able to identify several differences between the expert panel and laypeople. Conclusions: To ensure the relevance of wellness models, it is vital to understand the areas that laypeople consider to be important for their comprehensive wellness. This study offers 13 domains that could be combined with an expert view on wellness and used as a starting point for creating a more comprehensive, inclusive and better-suited wellness instrument.

- Abstract
It is of general interest to combine the faradaic processes based high energy density of a battery with the non-faradaic processes based high power density of a capacitor in one cell. Surface area and functional groups of electrode materials strongly affect these properties. For the anode material Li4Ti5O12 (LTO), we suggest a polaron based mechanism that influences Li ion uptake and mobility. Here we show electrolytes containing a lithium salt induce an observable change in the bulk NMR relaxation properties of LTO nano particles. The longitudinal 7Li NMR relaxation time of bulk LTO can change by almost an order of magnitude and, therefore, reacts very sensitively to the cation and its concentration in the surrounding electrolyte. The reversible effect is largely independent of the used anions and of potential anion decomposition products. It is concluded that lithium salt containing electrolytes increase the mobility of surface polarons. These polarons and additional lithium cations from the electrolyte can now diffuse through the bulk, induce the observed enhanced relaxation rate and enable the non-faradaic process. This picture of a Li+ equilibrium between electrolyte and solid may help with improving the charging properties of electrode materials.

Funding Information: Partial financial support was received from the Department of Emergency Care and Services, Helsinki University Hospital, University of Helsinki and Business Finland as a part of MASSE‐project (Personalised Care With Mass‐Production Efficiency). Publisher Copyright: © 2023 The Authors. Scandinavian Journal of Caring Sciences published by John Wiley & Sons Ltd on behalf of Nordic College of Caring Science. Background: People living in nursing homes face the risk of visiting the emergency department (ED). Outreach services are developing to prevent unnecessary transfers to ED. Aims: We aim to assess the performance of acute care services provided to people living in nursing homes or long-term homecare, focusing on ED transfer prevention, safety, cost-effectiveness and experiences. Materials & Methods: This review was guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Studies were eligible for inclusion if they were peer-reviewed and examined acute outreach services dedicated to delivering care to people in nursing homes or long-term homecare. The service models could also have preventive components. The databases searched were Scopus and CINAHL. In addition, Robins-I and SIGN checklists were used. The primary outcomes of prevented ED transfers or hospitalisations and the composite outcome of adverse events (mortality/Emergency Medical Service or ED visit after outreach service contact related to the same clinical condition) were graded with GRADE. Results: Fifteen relevant original studies were found—all were observational and focused on nursing homes. The certainty of evidence for acute outreach services with preventive components to prevent ED transfers or hospitalisations was low. Stakeholders were satisfied with these services. The certainty of evidence for solely acute outreach services to prevent ED transfers or hospitalisations was very low and inconclusive. Reporting of adverse events was inconsistent, certainty of evidence for adverse events was low. Conclusion: Published data might support adopting acute outreach services with preventive components for people living in nursing homes to reduce ED transfers, hospitalisations and possibly costs. If an outreach service is started, it is recommended that a cluster-randomised or quasi-experimental research design be incorporated to assess the effectiveness and safety of the service. More evidence is also needed on cost-effectiveness and stakeholders' satisfaction. Systematic review registration number: PROSPERO CRD42020211048, date of registration: 25.09.2020.

In many countries, potato (Solanum tuberosum) is a crucial carbohydrate-rich crop and staple food. However, sprouting during storage can adversely affect the quality of the harvested tubers. To maintain the postharvest quality, this study assessed the potential of apple fruit as one of the biological suppressants for potato tuber sprouting at ambient storage. Potato tubers were obtained from four commercial farms. Thereafter, they were stored in a brown paper alone (control) or with apple fruit at ±23 °C for 30-day period. Potato tubers were evaluated for their weight loss, sprouting percentage, decay and soluble sugars during storage duration. Tubers stored with apple fruit had significantly (P

Background Melasma is a highly prevalent chronic pigmentary disorder. The pathogenesis is unknown but melasma often occurs in photo-exposed areas, e.g., cheeks, upper lip, chin, and forehead. Tranexamic acid (TA), a plasmin inhibitor, aids in the inhibition of UV-induced plasmin activity and melanogenesis, making it a favorable therapeutic option for melasma. Tranexamic acid may be administered through various routes, e.g., topical. This study aimed to compare the efficacy of topical 10% versus 5% TA in women with melasma. Methods This double-blind randomized controlled trial included 16 females with epidermal type melasma who were randomized into two groups to receive either topical 10% TA (n = 8) or 5% TA (n = 8) applied twice daily for eight weeks. Prior to intervention and at 8 weeks after intervention, the intensity and extension of melasma were assessed based on melasma area and severity index (MASI) score and pigmentation score. Results Mean MASI and pigmentation scores in both treatment groups were similar at base-line (p>0.05). The reduction in MASI and pigmentation scores in the topical 10% TA and 5% TA groups was similar and statistically not significant after 4 and 8 weeks of treatment (p>0.05). There were no drug-related adverse reactions or complications. Conclusion This study demonstrated that topical 10% TA and 5% TA were effective in treating women with melasma. The utilization of topical 5% TA for melasma is a promising alternative therapeutic option without the need to increase the concentration of the formulation.

Given the high-level physiological functions and nutrient concentrations of bark that cover the entire trunks of huge trees, research into bark nutrient traits and the development of models that estimate the bark biomass of tropical trees is essential when it is sought to understand forest nutrient cycling and tree ecological traits. This study investigated the concentrations of six bark nutrients (nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), and sodium (Na)) by individual tree size and the soil nutrient concentrations for two major pioneer species (Macaranga gigantea and M. hosei) of Malaysia. To estimate bark biomass, allometric equations using tree diameter, height, and crown diameter were developed by combining previous data from adjacent forests with the present data. We found no significant relationship between tree size and most bark nutrient concentrations, though all nutrient concentrations of the two pioneer trees were significantly higher than those of primary forest tree species. Surprisingly, no relationship was found between the soil and bark nutrient concentrations for either species. All the size parameters used in the allometric equations accurately estimated bark biomass. There were no differences in equations between the two species when diameter served as an explanatory variable, but differences were apparent when height and crown diameter were so used. A comparison of allometric equations that yielded the bark biomasses of different types of forest showed that the bark biomass of the tropical secondary forest trees was less than half of that of tropical dry forest trees of the same diameter. Thus, the use of inappropriate equations and nutrient concentrations increases the possibility of serious errors in estimating bark biomass and forest nutrient cycles.

T cells are required to clear infection, and T cell motion plays a role in how quickly a T cell finds its target, from initial naive T cell activation by a dendritic cell to interaction with target cells in infected tissue. To better understand how different tissue environments affect T cell motility, we compared multiple features of T cell motion including speed, persistence, turning angle, directionality, and confinement of T cells moving in multiple murine tissues using microscopy. We quantitatively analyzed naive T cell motility within the lymph node and compared motility parameters with activated CD8 T cells moving within the villi of small intestine and lung under different activation conditions. Our motility analysis found that while the speeds and the overall displacement of T cells vary within all tissues analyzed, T cells in all tissues tended to persist at the same speed. Interestingly, we found that T cells in the lung show a marked population of T cells turning at close to 180o, while T cells in lymph nodes and villi do not exhibit this “reversing” movement. T cells in the lung also showed significantly decreased meandering ratios and increased confinement compared to T cells in lymph nodes and villi. These differences in motility patterns led to a decrease in the total volume scanned by T cells in lung compared to T cells in lymph node and villi. These results suggest that the tissue environment in which T cells move can impact the type of motility and ultimately, the efficiency of T cell search for target cells within specialized tissues such as the lung.

Nursing ,RT1-120 - Abstract
Introduction Managing a patient on mechanical ventilation is a vital aspect of clinical scope in intensive and critical care units. In addition, it is a highly technical, intricate, dynamic task requiring extensive knowledge and skills. Little is known about critical care nurses’ experiences caring for patients on mechanical ventilation in contexts where resources are constrained, creating an empirical gap in the available body of knowledge. Objective This study explored critical care nurses’ experiences caring for patients on mechanical ventilators at an intermediate hospital in northeastern Namibia. Method The study followed qualitative descriptive and explorative designs. The purposive sample included 13 critical care nurses who had cared for patients on mechanical ventilation for more than 6 months. Data were collected via individual unstructured interviews and analyzed using a reflexive thematic analysis approach. Results Four themes and eight subthemes emerged. Varied personal feelings, such as feeling proud, competent, exhausted, traumatized, overwhelmed, and concerns for patients’ well-being were experienced by critical care nurses. Participants described learning from colleagues in the unit and expressed concerns about not having postbasic training in critical care nursing. Negative experiences included concerns about community members’ misconceptions about critical care units and mechanical ventilators, and challenges with resources, personnel, and admission procedures. Conclusion Critical care nurses in resource-constrained settings have positive and negative experiences caring for patients on mechanical ventilators. The findings have implications for the development of support systems for critical care nurses, including induction programs, competence enhancement, psychological support, the development of guiding documents for admission, patient preparation and sensitization of community members. There is a need for this study to be replicated in other resource-constrained contexts where specialized critical care nurses are available.

Objective:. Awareness regarding the negative effects of ultraviolet radiation are commonly neglected in Asian countries. This study sought to evaluate the ultraviolet radiation knowledge and photoprotective behaviors of university students in Indonesia. Methods:. This observational cross-sectional was conducted at Pelita Harapan University, Indonesia. Results:. A total of 89 (45.4%) medical students and 107 (54.6%) nonmedical students participated in this study. Their mean age was 21.03 ± 2.03 years, and 46.4% of them had Fitzpatrick type III skin. Medical students as well as older students exhibited a higher level of knowledge regarding photoprotection (P ≤ 0.05). Factors related to good photoprotective behaviors were sex, older age, and average expenditure on skincare. Further analysis revealed that a high level of knowledge regarding photoprotection was related to acceptable photoprotective behaviors (P = 0.01; odds ratio = 1.97; 95% confidence interval = 1.13–3.54). Conclusions:. Knowledge regarding sun-related damage and practice of photoprotective behaviors were low among the participants. The results indicate that formal education and academic subjects should incorporate the topic of sun-related damage and promote the practice of photoprotective behaviors early on to increase awareness among populations.

The study was carried out to investigate the implications of the Namibian biosafety regulations on Namibian food and feed importers. After the Biosafety Act, 2006 (Act No. 7 of 2006), the biosafety regulation was gazetted in 2016, which saw the implementation of the national framework, the impact of food and feed importers was not known. The objective of the study was to assess the adoption and application of the national biosafety labelling regulations by food and feed importers. In addition, the impacts of these regulations on Namibian food and feed importers were assessed. The study used a structured online and hard copy survey questionnaire based on responses from 340 Namibian importers of food and feed products from eight identified Namibian regions: Khomas, Erongo, Kavango West, Kavango East, Omusati, Oshana, Ohangwena, Oshikoto, and Zambezi who have the knowledge required for the adoption and application of the Namibian biosafety labelling regulations. Using the Mann-Whitney test, the study confirmed that individuals who are aware of the biosafety Act, 2006 (Act No. 7 of 2006) are less likely to agree with statements such as experiencing problems in fulfilling requirements under the biosafety regulations. It was further concluded that there is a need to reduce the current administrative burdens for handling applications and improve dialogue between regulators and the food and feed importing industry while increasing the competence of regulators and creating more labelling regulation awareness for food and feed importers. The study further suggests that public awareness is required beyond food and feed importers.

The design and production of incurred test materials are critical for the development and validation of methods for food allergen analysis. This is because production and processing conditions, together with the food matrix, can modify allergens affecting their structure, extractability and detectability. For the ThRAll project, which aims to develop a mass spectrometry–based reference method for the simultaneous accurate quantification of six allergenic ingredients in two hard to analyse matrices. Two highly processed matrices, chocolate bars and broth powder, were selected to incur with six allergenic ingredients (egg, milk, peanut, soy, hazelnut and almond) at 2, 4, 10 and 40 mg total allergenic protein/kg food matrix using a pilot-scale food manufacturing plant. The allergenic activity of the ingredients incurred was verified using food-allergic patient serum/plasma IgE, the homogeneity of the incurred matrices verified and their stability at 4 °C assessed over at least 30-month storage using appropriate enzyme-linked immunosorbent assays (ELISA). Allergens were found at all levels from the chocolate bar and were homogenously distributed, apart from peanut and soy which could only be determined above 4 mg total allergenic ingredient protein/kg. The homogeneity assessment was restricted to analysis of soy, milk and peanut for the broth powder but nevertheless demonstrated that the allergens were homogeneously distributed. All the allergens tested were found to be stable in the incurred matrices for at least 30 months demonstrating they are suitable for method development.

- Abstract
During early childhood, children develop a moral self-concept (MSC), reflecting the representation of their own moral behavioral preferences. Little is known about the developmental processes that relate to the emergence of the MSC. This longitudinal study followed participants from infancy to preschool age ( n = 99-139; 49%-55% girls, 45%-51% boys, mostly Caucasian). It investigated the relations between the quality of early social interactions, prosocial behaviors, and the development of the MSC. We assessed maternal emotional availability at 1 year of age, children's prosocial behaviors (helping, sharing, comforting) at 3 years of age, and their MSC at 4 years of age. Children's comforting and sharing behavior at 3 years of age, but not their helping behavior, was associated with their MSC development. Interestingly, maternal emotional availability predicted MSC indirectly through its relation to children's comforting behavior, suggesting a mediated pathway. The study highlights developmental trajectories from early social interactions to how children think about their own prosociality. (PsycInfo Database Record (c) 2025 APA, all rights reserved).

- Abstract
We investigated the relationships among the moral self-concept, arousal reactions to third-party moral situations, and moral judgment in 5- to 7-year-old children (N = 59). Children's moral self-concept was assessed using a puppet task. In addition, children were shown audiovisual scenes depicting prosocial, antisocial, and neutral interactions between children. We measured phasic pupil dilation responses to the actions and collected children's judgments of the actions. The results show that children judged antisocial behavior as more negative and prosocial behavior as more positive than neutral behavior. In addition, children showed significantly higher arousal when observing antisocial behavior compared with neutral and prosocial behavior. Moreover, children's moral judgment related to their arousal: the more negative the moral judgment, the higher the arousal, even in prosocial and neutral scenarios. Finally, children's moral self-concept correlated with their explicit judgments, but not with their physiological arousal. These results support developmental theories suggesting a relationship between the moral self and moral judgment., (Copyright © 2024 The Authors. Published by Elsevier Inc. All rights reserved.)

- Abstract
Evaluating whether someone's behavior is praiseworthy or blameworthy is a fundamental human trait. A seminal study by Hamlin and colleagues in 2007 suggested that the ability to form social evaluations based on third-party interactions emerges within the first year of life: infants preferred a character who helped, over hindered, another who tried but failed to climb a hill. This sparked a new line of inquiry into the origins of social evaluations; however, replication attempts have yielded mixed results. We present a preregistered, multi-laboratory, standardized study aimed at replicating infants' preference for Helpers over Hinderers. We intended to (1) provide a precise estimate of the effect size of infants' preference for Helpers over Hinderers, and (2) determine the degree to which preferences are based on social information. Using the ManyBabies framework for big team-based science, we tested 1018 infants (567 included, 5.5-10.5 months) from 37 labs across five continents. Overall, 49.34% of infants preferred Helpers over Hinderers in the social condition, and 55.85% preferred characters who pushed up, versus down, an inanimate object in the nonsocial condition; neither proportion differed from chance or from each other. This study provides evidence against infants' prosocial preferences in the hill paradigm, suggesting the effect size is weaker, absent, and/or develops later than previously estimated. As the first of its kind, this study serves as a proof-of-concept for using active behavioral measures (e.g., manual choice) in large-scale, multi-lab projects studying infants., (© 2024 John Wiley & Sons Ltd.)

- Abstract
Expectations about how others' actions unfold in the future are crucial for our everyday social interactions. The current study examined the development of the use of kinematic cues for action anticipation and prediction in 3-year-olds, 4-year-olds, 10-year-olds, and adults in two experiments. Participants observed a hand repeatedly reaching for either a close or far object. The motor kinematics of the hand varied depending on whether the hand reached for the close or far object. We assessed whether participants would use kinematic cues to visually anticipate (Experiment 1; N=98) and verbally predict (Experiment 2; N=80) which object the hand was going to grasp. We found that only adults, but not 3- to 10-year-olds, based their visual anticipations on kinematic cues (Experiment 1). This speaks against claims that action anticipations are based on simulating others' motor processes and instead provides evidence that anticipations are based on perceptual mechanisms. Interestingly, 10-year-olds used kinematic cues to correctly verbally predict the target object, and 4-year-olds learned to do so over the trials (Experiment 2). Thus, kinematic cues are used earlier in life for explicit action predictions than for visual action anticipations. This adds to a recent debate on whether or not an implicit understanding of others' actions precedes their ability to verbally reason about the same actions., (Copyright © 2024 The Authors.

31. Microscopic Structure of Neat Linear Alkylamine Liquids: An X-Ray Scattering and Computer Simulation Study.

- Abstract
Linear amines, from propylamine to nonylamine, are studied under ambient conditions by X-ray scattering and molecular dynamics simulations of various force field models. The major finding is that the prepeak in alkylamines is about 1 order of magnitude weaker than that in alkanols, hence suggesting much weaker hydrogen bonding-induced clustering of the amine groups than for the hydroxyl groups. Computer simulation studies reveal that the OPLS-UA model reproduces the prepeak, but with larger amplitudes, while the GROMOS-UA and CHARMM-AA force fields show almost no prepeak. Simulations of all models show the existence of hydrogen-bonded clusters, equally confirmed by the prominent prepeak of the structure factor between the nitrogen atoms. The hydrogen bond strength, as modeled by the Coulomb association in classical force field models, is about the same order of magnitude for both systems. Then, one may ask what is the origin of the weaker prepeak in alkylamines? Simulation data reveal that the existence of the prepeak is controlled through the cancellation of the positive contributions from the charged group correlations by the negative contributions from the cross charged-uncharged correlations. The C
2v symmetry of the amine headgroup hinders clustering, which favors cross correlations with the tail atoms. This is opposite to alkanols where the symmetry of the hydroxyl headgroup favors clustering and hinders cross correlations with the alkyl tail. This competition between charged and uncharged atomic groups appears as a general mechanism to explain the existence of scattering prepeaks, including their position and amplitude.- Published

- Abstract
Aims: Data on the clinical profiles of patients with transthyretin amyloidosis cardiomyopathy (ATTR-CM) in the post-approval era of tafamidis 61 mg are lacking. Study aims were characterization of contemporary ATTR-CM patients, analysis of potential eligibility for the 'Transthyretin Amyloidosis Cardiomyopathy Clinical Trial' (ATTR-ACT) and identification of factors associated with the decision on tafamidis 61 mg treatment., Methods and Results: This retrospective study analysed ATTR-CM patients seen at eight University Hospitals in the first year after approval of tafamidis 61 mg for ATTR-CM in Germany (April 2020 to March 2021). The cohort comprised 366 patients (median age 79 [74; 82] years, 84% male), with 47% and 45% of the cohort being in National Amyloidosis Centre ATTR stage ≥ II and NYHA class ≥ III, respectively. Sixty-four per cent of patients met key eligibility criteria of the pivotal ATTR-ACT. In recently diagnosed patients (58% with diagnosis ≤6 months), the rate of variant ATTR was significantly lower than in patients diagnosed more than 6 months ago (9.3% vs. 19.7%). Of the 293 patients without prior ATTR specific treatment, tafamidis 61 mg was newly initiated in 77%. Patients with tafamidis 61 mg treatment were significantly younger, were more often eligible for ATTR-ACT, had lower NYHA class and higher serum albumin levels. These variables explained 16% of the variance of treatment decision. Unadjusted survival was higher in patients with than those without treatment (1-year survival 98.6% vs. 87.3%, P < 0.001)., Conclusions: Wild-type ATTR was the primary aetiology amongst contemporary ATTR-CM patients and almost two-thirds of patients were in an advanced disease stage. Clinical profiles of 64% of patients in routine care matched those of the ATTR-ACT. Further effort is needed to detect patients at an earlier disease stage and to validate criteria justifying treatment initiation., (© 2024 The Author(s).

- Abstract
Attachment theory proposes that young children's experiences with their caregivers has a tremendous influence on how children navigate their social relationships. By the end of early childhood, intergroup contexts play an important role in their social life and children build strong ties to their ingroups. Although both domains relate to the same psychological processes-children's affective ties to others-surprisingly very little research has addressed how children's attachment relates to their intergroup attitudes and behavior. In this study, we investigate the link. For that purpose, 5-year-old children (n = 100) first underwent the German Attachment Story Completion Task (GEV-B). Then we allocated children into minimal groups based on T-Shirt color and assessed their intergroup attitudes and intergroup behavior. Results showed that while most children showed a strong and robust ingroup bias in their attitudes and behavior, children with an insecure-ambivalent attachment representation treated in- and outgroup similarly. Overall, this study provides novel perspectives on the relationship between children's attachment representation and their interactions in the social world. RESEARCH HIGHLIGHTS: This study provides novel insights into the relationship between children's attachment security and the development of intergroup bias in a minimal group context Children with secure, insecure-avoidant and disorganized attachment representation showed a strong intergroup bias in explicit attitudes and behavior Children with insecure-ambivalent attachment representation displayed no intergroup bias Insecure-ambivalent attachment representations might be detrimental to the formation of ingroup attachment., (© 2024 The Authors.

- Abstract
Aims: Plasma NT-proBNP is an established marker of heart failure. Previous studies suggested urinary NT-proBNP has potential as marker of chronic heart failure as well. The objective of this study was to compare urinary NT-proBNP to plasma NT-proBNP in a real-life collective of patients with an ICD, especially regarding ICD-therapies., Methods & Results: NT-proBNP was assessed in plasma and fresh spot urine (the latter related to urinary creatinine) from 322 patients of our ICD outpatient clinic. 54 healthy individuals served as a control group. Follow-up regarding mortality and ICD therapies was performed after 32 months (IQR 5-35 months). Plasma and urinary NT-proBNP was positively correlated (r = 0.89, p < 0,001). According to ROC analysis urinary NT-proBNP detected LV dysfunction (EF<35 % vs. healthy CTRL) with very satisfying predictive values (AUC 0.95), but plasma NT-proBNP showed slightly better values (AUC 0.99). Patients who received appropriate ICD-shock-therapies showed significantly higher plasma (p < 0.001) as well as urinary NT-proBNP levels (p = 0.011) compared to patients without shock-therapy. In Kaplan-Meier analysis, plasma as well as urinary NT-proBNP levels > Youden-Index showed significantly higher event rates for appropriate ICD-shock therapies (p < 0.001 and p = 0.016) and the combined endpoint of all-cause-mortality and shock therapies (each p < 0.001). Urinary and plasma NT-proBNP were independent predictors for appropriate ICD-shock-therapies and for the combined endpoint of all-cause mortality and appropriate ICD-shock-therapies (each p < 0.001)., Conclusion: Urinary NT-proBNP as a marker for LV dysfunction and symptomatic heart failure showed promising predictive values. Associations between plasma as well as urinary NT-proBNP and ICD shock-therapies could be shown., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Indian Heart Rhythm Society.

- Abstract
Electric pacing of human induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CM) has been increasingly used to simulate cardiac arrhythmias in vitro and to enhance cardiomyocyte maturity. However, the impact of electric pacing on cellular electrophysiology and Ca
2+ handling in differentiated hiPSC-CM is less characterized. Here we studied the effects of electric pacing for 24 h or 7 days at a physiological rate of 60 beats/min on cellular electrophysiology and Ca2+ cycling in late-stage, differentiated hiPSC-CM (>90% troponin+ , >60 days postdifferentiation). Electric culture pacing for 7 days did not influence cardiomyocyte cell size, apoptosis, or generation of reactive oxygen species in differentiated hiPSC-CM compared with 24-h pacing. However, epifluorescence measurements revealed that electric pacing for 7 days improved systolic Ca2+ transient amplitude and Ca2+ transient upstroke, which could be explained by elevated sarcoplasmic reticulum Ca2+ load and SERCA activity. Diastolic Ca2+ leak was not changed in line-scanning confocal microscopy, suggesting that the improvement in systolic Ca2+ release was not associated with a higher open probability of ryanodine receptor (RyR)2 during diastole. Whereas bulk cytosolic Na+ concentration and Na+ /Ca2+ exchanger (NCX) activity were not changed, patch-clamp studies revealed that chronic pacing caused a slight abbreviation of the action potential duration (APD) in hiPSC-CM. We found in whole cell voltage-clamp measurements that chronic pacing for 7 days led to a decrease in late Na+ current, which might explain the changes in APD. In conclusion, our results show that chronic pacing improves systolic Ca2+ handling and modulates the electrophysiology of late-stage, differentiated hiPSC-CM. This study might help to understand the effects of electric pacing and its numerous applications in stem cell research including arrhythmia simulation. NEW & NOTEWORTHY Electric pacing is increasingly used in research with human induced pluripotent stem cell cardiomyocytes (hiPSC-CM), for example to simulate arrhythmias but also to enhance maturity. Therefore, it is mandatory to understand the effects of pacing itself on cellular electrophysiology in late-stage, matured hiPSC-CM. This study provides an electrophysiological characterization of the effects of chronic electric pacing at a physiological rate on differentiated hiPSC-CM.- Published

- Abstract
From early on, infants show a preference for infant-directed speech (IDS) over adult-directed speech (ADS), and exposure to IDS has been correlated with language outcome measures such as vocabulary. The present multi-laboratory study explores this issue by investigating whether there is a link between early preference for IDS and later vocabulary size. Infants' preference for IDS was tested as part of the ManyBabies 1 project, and follow-up CDI data were collected from a subsample of this dataset at 18 and 24 months. A total of 341 (18 months) and 327 (24 months) infants were tested across 21 laboratories. In neither preregistered analyses with North American and UK English, nor exploratory analyses with a larger sample did we find evidence for a relation between IDS preference and later vocabulary. We discuss implications of this finding in light of recent work suggesting that IDS preference measured in the laboratory has low test-retest reliability.

- Abstract
The socioeconomic costs of neurodegenerative diseases (NDs) are highly affected by comorbidities. This study aims to enhance our understanding of the prevalent complications of NDs through the lens of network analysis. A multimorbidity network (MN) was constructed based on a longitudinal EHR dataset of 93,647,498 diagnoses of 824,847 patients. The association between the conditions was measured by two metrics, i.e. Phi-correlation and Cosine Index (CI). Based on multiple network centrality measures, a fused ranking list of the prevalent multimorbidities was provided. Finally, class-level networks depicting the prevalence and strength of diseases in different classes were constructed. The general MN included 928 diseases and 337,253 associations. Considering a 99% confidence level, two networks of 575 relationships were constructed based on Phi-correlations (73 diseases) and CI (102 diseases). Five out of 19 ICD-9 categories did not appear in either of the networks. Also, ND's immediate MNs for the top 50% of the significant associations included 42 relationships, whereas the Phi-correlation and CI networks included 36 and 34 diseases, respectively. Thirteen diseases were identified as the most notable multimorbidities based on various centrality measures. The analysis framework helps practitioners toward better resource allocations, more effective preventive screenings, and improved quality of life for ND patients and caregivers.

- Abstract
The mechanisms underlying the developing sense of bodily self are debated. Whereas some scholars stress the role of sensory factors, others propose the importance of contextual factors. By manipulating multisensory stimulation and social familiarity with the other person, we explored two factors that are proposed to relate to young children's developing sense of bodily self. Including an adult sample allowed us to investigate age-related differences of the malleability of the bodily self. To this end, the study implemented an enfacement illusion with children (N = 64) and adults (N = 33). Participants were exposed to one trial with synchronous interpersonal multisensory stimulation and one trial with asynchronous interpersonal multisensory stimulation-either with a stranger or with the mother as the other person. A self-recognition task using morph videos of self and other and an enfacement questionnaire were implemented as dependent measures. Results revealed evidence for the presence of the enfacement effect in children in both measures. The identity of the other person had a significant effect on the self-recognition task. Contrary to our hypothesis, the effect was significantly smaller in the caregiver condition. No significant differences between children and adults emerged. Our results demonstrate the role of both multisensory stimulation and contextual-here social familiarity-factors for the construction and development of a bodily self. The study provides developmental science with a novel approach to the bodily self by showing the validity of the self-recognition task in a child sample. Overall, the study supports proposals that the sense of bodily self is malleable early in development., (Copyright © 2024 The Author(s). Published by Elsevier Inc. All rights reserved.)

- Abstract
The effects and mechanisms of cardiac arrhythmias are still incompletely understood and an important subject of cardiovascular research. A major difficulty for investigating arrhythmias is the lack of appropriate human models. Here, we present a protocol for a translational simulation of different types of arrhythmias using human induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CM) and electric cell culture pacing. The protocol comprises the handling of ventricular and atrial hiPSC-CM before and during in vitro arrhythmia simulation and possible arrhythmia simulation protocols mimicking clinical arrhythmias like atrial fibrillation. Isolated or confluent hiPSC-CM can be used for the simulation. In vitro arrhythmia simulation did not impair cell viability of hiPSC-CM and could reproduce arrhythmia associated phenotypes of patients. The use of hiPSC-CM enables patient-specific studies of arrhythmias, genetic interventions, or drug-screening. Thus, the in vitro arrhythmia simulation protocol may offer a versatile tool for translational studies on the mechanisms and treatment options of cardiac arrhythmias., Competing Interests: STS received speakers/consulting honoraria from Astra Zeneca, Novartis, Berlin-Chemie, DAIICHI SANKYO, Bristol-Myers-Squibb, Pfizer, Boehringer Ingelheim, Lilly.

- Abstract
Despite a few recent reports on Rashba effects in two-dimensional (2D) Ruddlesden-Popper (RP) hybrid perovskites, the precise role of organic spacer cations in influencing Rashba band splitting remains unclear. Here, using a combination of temperature-dependent two-photon photoluminescence (2PPL) and time-resolved photoluminescence spectroscopy, alongside density functional theory (DFT) calculations, we contribute to significant insights into the Rashba band splitting found for 2D RP hybrid perovskites. The results demonstrate that the polarity of the organic spacer cation is crucial in inducing structural distortions that lead to Rashba-type band splitting. Our investigations show that the intricate details of the Rashba band splitting occur for organic cations with low polarity but not for more polar ones. Furthermore, we have observed stronger exciton-phonon interactions due to the Rashba-type band splitting effect. These findings clarify the importance of selecting appropriate organic spacer cations to manipulate the electronic properties of 2D perovskites.

- Abstract
We investigated the effect of the NaCl concentration (0.3-2M) on the structure and dynamics of hen egg yolk at room temperature and during thermal gelation at temperatures in the range of 66-90 °C utilizing low-dose x-ray photon correlation spectroscopy in ultra-small angle x-ray scattering geometry. With an increase in the salt concentration, we observe progressive structural and dynamic changes at room temperature, indicating the disruption of yolk components such as yolk-granules and yolk-plasma proteins. Temperature- and salt-dependent structural and dynamic investigations suggest a delay in the gel formation and aggregation of yolk low-density lipoproteins with increasing ionic strength. However, the time-temperature superposition relationship observed in all samples suggests an identical mechanism underlying protein aggregation-gelation with a temperature-dependent reaction rate. The sol-gel transition time extracted from kinetic and dynamic information follows Arrhenius's behavior, and the activation energy (460 kJ/mol) is found to be independent of the salt concentration., (© 2024 Author(s).

- Abstract
The functionality and efficiency of proteins within a biological membrane are highly dependent on both the membrane lipid composition and the physiochemical properties of the solution. Lipid mesophases are directly influenced by changes in temperature, pH, water content or due to individual properties of single lipids such as photoswitchability. In this work, we were able to induce light- and temperature-driven mesophase transitions in a model membrane system containing a mixture of 1,2-dipalmitoyl-phosphatidylcholine phospholipids and azobenzene amphiphiles. We observed reversible and reproducible transitions between the lamellar and Pn3m cubic phase after illuminating the sample for 5 min with light of 365 and 455 nm wavelengths, respectively, to switch between the cis and trans states of the azobenzene N=N double bond. These light-controlled mesophase transitions were found for mixed complexes with up to 20% content of the photosensitive molecule and at temperatures below the gel-to-liquid crystalline phase transition temperature of 33°C. Our results demonstrate the potential to design bespoke model systems to study the response of membrane lipids and proteins upon changes in mesophase without altering the environment and thus provide a possible basis for drug delivery systems., (open access.)

- Abstract
Femtosecond high-intensity laser pulses at intensities surpassing 10
14 W/cm2 can generate a diverse range of functional surface nanostructures. Achieving precise control over the production of these functional structures necessitates a thorough understanding of the surface morphology dynamics with nanometer-scale spatial resolution and picosecond-scale temporal resolution. In this study, we show that single XFEL pulses can elucidate structural changes on surfaces induced by laser-generated plasmas using grazing-incidence small-angle X-ray scattering (GISAXS). Using aluminium-coated multilayer samples we distinguish between sub-picosecond (ps) surface morphology dynamics and subsequent multi-ps subsurface density dynamics with nanometer-depth sensitivity. The observed subsurface density dynamics serve to validate advanced simulation models representing matter under extreme conditions. Our findings promise to open new avenues for laser material-nanoprocessing and high-energy-density science.- Published

- Abstract
Children's moral self-concept (MSC) has been proposed to relate to prosocial behaviour. However, systematic assessments of their inter-relations are scarce. Therefore, this longitudinal study investigated the development, structure and inter-relation of prosocial behaviours and the MSC in childhood, using three measurement points at ages 4, 5 and 6 years. We assessed children's MSC and helping, sharing and comforting behaviours in a laboratory setting. Confirmatory factor analyses revealed a three-dimensional MSC structure at 5 and 6 years, but not at 4 years. There was inconsistent stability across time points regarding prosocial behaviour and MSC. For the comforting domain, but not the other domains, cross-lagged relations between self-concept and behaviour were present. Moreover, helping behaviour and self-concept were inter-related at 6 years. Results provide support for reciprocal associations between MSC and prosocial behaviour, albeit only in the comforting domain. They highlight the importance of distinguishing between types of prosocial behaviour and corresponding dimensions of the self-concept, as different developmental trajectories and associations emerge., (© 2024 The Authors.

- Abstract
The emergence of the pointing gesture is a major developmental milestone in human infancy. Pointing fosters preverbal communication and is key for language and theory of mind development. Little is known about its ontogenetic origins and whether its pathway is similar across different cultures. The goal of this study was to examine the theoretical proposal that social pointing is preceded by a non-social use of the index finger and later becomes a social-communicative gesture. Moreover, the study investigated to which extent the emergence of social pointing differs cross-culturally. We assessed non-social index-finger use and social pointing in 647 infants aged 3- to 24 months from 4 different countries (China, Germany, Japan, and Türkiye). Non-social index-finger use and social pointing increased with infants' age, such that social pointing became more dominant than non-social index-finger use with age. Whereas social pointing was reported across countries, its reported frequency differed between cultures with significantly greater social pointing frequency in infants from Türkiye, China, and Germany compared to Japanese infants. Our study supports theoretical proposals of the dominance of non-social index-finger use during early infancy with social pointing becoming more prominent as infants get older. These findings contribute to our understanding of infants' use of their index finger for social and non-social purposes during the first two years of life., Competing Interests: Declaration of Competing Interest None., (Copyright © 2024 The Authors.

- Abstract
Individuals experiencing suicidal thoughts and behaviors (STBs) show less specificity and positivity during episodic future thinking (EFT). Here, we present findings from two studies aiming to (1) further our understanding of how STBs may relate to neural responsivity during EFT and (2) examine the feasibility of modulating EFT-related activation using real-time fMRI neurofeedback (rtfMRI-nf). Study 1 involved 30 individuals with major depressive disorder (MDD; half with STBs) who performed an EFT task during fMRI, for which they imagined personally-relevant future positive, negative, or neutral events. Positive EFT elicited greater ventromedial prefrontal cortex (vmPFC) activation compared to negative EFT. Importantly, the MDD + STB group exhibited reduced vmPFC activation across all EFT conditions compared to MDD-STB; although EFT fluency and subjective experience remained consistent across groups. Study 2 included rtfMRI-nf focused on vmPFC modulation during positive EFT for six participants with MDD + STBs. Results support the feasibility and acceptability of the rtfMRI-nf protocol and quantitative and qualitative observations are provided to help inform future, larger studies aiming to examine similar neurofeedback protocols. Results implicate vmPFC blunting as a promising treatment target for MDD + STBs and suggest rtfMRI-nf as one potential technique to explore for enhancing vmPFC engagement., Competing Interests: Declaration of competing interest Dr. Martin Paulus has received royalties for an article about methamphetamine published in UpToDate.

- Abstract
Developmental science has experienced a vivid debate on whether young children prioritize goals over means in their prediction of others' actions. Influential developmental theories highlight the role of goal objects for action understanding. Yet, recent infant studies report evidence for the opposite. The empirical evidence is therefore inconclusive. The current study advanced this debate by assessing preschool children's verbal predictions of others' actions. In five experiments (N = 302), we investigated whether preschool children and adults predict agents to move towards their previous goal (that is, show goal-related predictions) or predict agents to move along the same movement path that they pursued before. While Experiments 1a, 1b and 1c presented young children and adults with animated agents, Experiments 2a and 2b presented participants with human grasping action. An integrative analysis across experiments revealed that children were more likely to predict the agent to move along the same movement path, Z = -4.574, p ≤ 0.0001 (r = 0.304). That is, preschool children were more likely to predict that agents would move along the same trajectory even though this action would lead to a new goal object. Thus, our findings suggest that young children's action prediction relies on the detection of spatial and movement information. Overall, we discuss our findings in terms of theoretical frameworks that conceive of action understanding as an umbrella term that comprises different forms and facets in which humans understand others' actions. RESEARCH HIGHLIGHTS: We investigated whether preschool children predict agents to move towards their previous goal or to move along the same movement path that they pursued before. Unlike adults, preschool children predicted that agents would move along the same trajectory even though this action would lead to a new goal. Adults' goal-based predictions were affected from contextual details, whereas children systematically made path-based predictions. Young children's action prediction relies on the detection of spatial and movement information., (© 2023 The Authors. Developmental Science published by John Wiley & Sons Ltd.)

- Abstract
Introduction Physical therapy (PT) is an effective nonoperative treatment for various orthopedic diagnoses. However, patients may have many reasons to dismiss PT, including favoring another intervention for their injury, time constraints, transportation, and cost. This dismissal of PT may contribute to inadequate patient compliance. This study aimed to elucidate patient compliance with a basic PT prescription and whether PT led to subjective injury improvement. Methods This is a retrospective study of patients observed in Stony Brook Orthopedic clinics from 08/01/2022 to 12/23/2022. Patients prescribed PT received a phone call six weeks after the PT prescription. The primary outcome was patient attendance at PT. Secondary outcomes were subjective; symptomatic improvement was listed as better, worse, or the same. Chi-square testing was used to compare outcomes. Results A total of 100 patients were enrolled in the study. Patients prescribed PT following surgery were more likely to attend compared to patients prescribed PT as a primary treatment (P value=0.027). The association between attendance at PT and a change in subjective symptoms (better, worse, same) was not significant. Patients' age, sex, and chronicity of injury were not significant factors in PT attendance. Of the 40 patients who did not attend PT, 14 cited time constraints, 11 utilized self-directed treatment, three cited insurance, two cited transportation, and 10 cited other reasons. Conclusions Overall, postoperative patients were more likely to attend PT compared to patients prescribed PT as a primary treatment. Factors such as age, sex, and chronicity of injury did not affect whether a patient attended PT. Of the patients enrolled, 71% stated subjective improvement in symptoms, but there was no association between symptoms and PT attendance. This study highlights the characteristics of those patient factors that may influence PT compliance and underscores the importance of further research into the population most likely to attend and benefit from PT., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2024, Leatherwood et al.)

- Abstract
As the COVID-19 pandemic further unfolds, it becomes a key theoretical and practical question to identify trajectories of child psychological well-being and to explore risk and resilience factors for developmental adjustment. The current study addressed this research gap by means of an ecological design: A (lockdown)-B (relaxation)-B (relaxation)-A (lockdown). We collected parental reports via online questionnaires over four measurement occasions during the COVID-19 pandemic in Germany (non-probabilistic sample): from the first lockdown (T1-spring 2020, N = 1769) to the following period of relaxation (T2-summer 2020, n = 873; T3-fall 2020, n = 729) on to the second lockdown (T4-winter 2020/21, n = 748). Key measures at T1-T4 were child emotional and behavioral problems as well as hyperactivity, child emotional and family-related well-being, parental strain, and parent-child relationship quality. We found evidence for quadratic growth models. While child problem behaviors (b = 0.32, p < 0.001) and emotional well-being (b = - 0.33, p < 0.001) improved after the first lockdown during subsequent periods of relaxation before worsening again in the second lockdown, child family-related well-being steadily decreased over all four measurement points (T1-T2: p < 0.001; T2-T3: p = 0.045; T3-T4: p = 0.030). Importantly, parental stress emerged as a strong risk factor (ps < 0.11) and the parent-child relationship quality constituted a resilience factor (p = 0.049) for child psychological well-being. These findings have major implications for policies aiming to further child health during the COVID-19 pandemic., (© 2023. The Author(s).)

- Abstract
The moral self-concept (MSC) is an early indicator of how children view themselves as moral agents. It has been proposed that an important feature of an established self-concept (SC) is sufficient coherency in how one views oneself. Furthermore, the MSC is expected to develop into a multidimensional, hierarchical construct which is stable over time. Investigating these theoretical hypotheses, this study aims to take three aspects into account to get a deeper insight into when and how the MSC first emerges: emergence of coherency, stability, and a differentiated structure. Preschoolers were presented with a puppet-interview at two measurement points (T1: M = 4.21 years, T2: M = 5.43 years, N = 108-133; 51%-57% female, largely Caucasian). The interview comprises three moral (helping, sharing, comforting), a physical, and a verbal self-concept scale. To investigate whether children had an established SC and therefore answered coherently, we analyzed children's response patterns resulting in a coherency-score: The greater answers vary within scales, the lower children score. Coherency of the MSC rose significantly across preschool period: At age 5, children answered largely coherently. Coherency of children's MSC related to its stability, meaning that the MSC was mostly stable for children with high coherency at T1. Factor analysis confirmed a multidimensional structure of the MSC at age 5, but not at age 4. The results demonstrate that a coherent and differentiated MSC is acquired within the preschool period. This offers a new approach to investigate the emergence of the SC in early development by integrating the important aspect of coherency into the area of SC research.
