“We’re Just Talking”: Constructing a Recent Trend in Emerging Adult Romantic Relationship Development

Emerging adults’ relationship development is an increasingly multi-faceted process characterized by ambiguity. Just talking has emerged as a phrase to characterize early relationship formation in popular culture, yet it remains understudied in the empirical literature. Constructivist grounded theory was used to explore this phenomenon in modern romantic relationship formation employing nine focus groups (N = 52) of emerging adult men and women from two large Midwestern universities. Eleven unique themes were generated to identify how emerging adult men and women conceptualize just talking (pre-dating, ambiguity about commitment, unofficial romantic label), reasons for just talking (pressure to keep options open, protection from rejection, testing the waters, avoiding defining the relationship), and how technology may facilitate the just talking process (increases the pool of potential partners, comfortable frequent contact, image crafting, less effort required). The findings have substantial implications for educators, clinicians, and other professionals who work with emerging adults.

Implementation of Postpartum Nutritional Interventions in Healthcare, Community and eHealth: A Systematic Review.

The efficacy of interventions targeting lifestyle habits, particularly dietary habits, among postpartum women is well established. However, whether these results can be translated into tangible changes in the care and services provided to this population remains unclear. Therefore, the aim is to examine the implementation outcomes of postpartum nutritional interventions delivered in healthcare, community, or eHealth settings. A search was conducted in the MEDLINE, EMBASE, Web of Science, CINAHL, and Cochrane Library databases in July 2024, to identify all relevant studies. Included studies had to report at least 1 of the 8 implementation outcomesstudied: acceptability, adoption, appropriateness, implementation cost, feasibility, fidelity, penetration, and sustainability. Study selection and data extraction were performed by two independent reviewers. Descriptive analysis of reported outcomes was performed. CRD42022351411. Of the 8907 unique studies identified, 26 interventions (24 publications) were included.There was a great heterogeneity among interventions studied and implementation outcomes reported. Acceptability, feasibility, and fidelity were the most studied implementation outcomes. Overall, postpartum nutritional interventions were found to be acceptable and useful, but improvements were suggested by participants, such as more frequent contacts and longer programs. Recruitment, retention, participation, and penetration rates widely varied across studies. Challenges hindering the delivery of nutritional interventions were reported by participants, such as lack of time and the presence of medical conditions following delivery. CONCLUSIONSFOR PRACTICE: This review demonstrates the potential forthe delivery and implementation of nutritional interventions in real-world settings during the postpartum period.

Late-life suicide: machine learning predictors from a large European longitudinal cohort.

People in late adulthood die by suicide at the highest rate worldwide. However, there are still no tools to help predict the risk of death from suicide in old age. Here, we leveraged the Survey of Health, Ageing, and Retirement in Europe (SHARE) prospective dataset to train and test a machine learning model to identify predictors for suicide in late life. Of more than 16,000 deaths recorded, 74 were suicides. We matched 73 individuals who died by suicide with people who died by accident, according to sex (28.8% female in the total sample), age at death (67 ± 16.4 years), suicidal ideation (measured with the EURO-D scale), and the number of chronic illnesses. A random forest algorithm was trained on demographic data, physical health, depression, and cognitive functioning to extract essential variables for predicting death from suicide and then tested on the test set. The random forest algorithm had an accuracy of 79% (95% CI 0.60-0.92, p = 0.002), a sensitivity of.80, and a specificity of.78. Among the variables contributing to the model performance, the three most important factors were how long the participant was ill before death, the frequency of contact with the next of kin and the number of offspring still alive. Prospective clinical and social information can predict death from suicide with good accuracy in late adulthood. Most of the variables that surfaced as risk factors can be attributed to the construct of social connectedness, which has been shown to play a decisive role in suicide in late life.

The in- and outpatient health care use of patients with COPD before and after initiation of home care: a registry study from Norway

Objective Chronic obstructive pulmonary disease (COPD) is a common condition associated with age, multimorbidity and frequently involves the use of health care across levels. Understanding the factors associated with the initiation of long-term care is important when planning the future need for services. We describe healthcare use before and after the reception of any home care. We further studied the associations between healthcare use and first registered home care service and from first registered home care service to nursing home admission or death. Design and subjects Patients residing in Oslo or Trondheim at the time of first contact with a COPD primary diagnosis, 2009–2018. Patient data were linked across national and municipal registries, covering healthcare and sociodemographics. The sample consisted of 16,738 individuals. Results There was a marked increase in inpatient and outpatient hospital contacts in the years prior to and after the reception of any home care. Adjusted for comorbidities and sociodemographics, high numbers of GP consultations, and inpatient and outpatient hospital contacts for respiratory diagnoses were associated with a significantly higher likelihood of receiving home care the next year (hazard odds ratios > 1.3). Following the reception of home care, the type of home care service received (e.g. home nursing or short-term rehabilitation/treatment) was more important than outpatient services in predicting next-year nursing home admission or death. Conclusion Including data on prior outpatient care when predicting future need for home care is beneficial. A high frequency (top 10%) of yearly GP, in- or outpatient hospital contacts can imply that the patient may be in need of home care in the near future.

Harm Reduction in Peer-Assisted Telemedicine for Hepatitis C: Secondary Outcomes of a Randomized Controlled Trial.

Hepatitis C (HCV) treatment for people who use drugs (PWUD) decreases injection drug use and injection equipment sharing. We examined changes in injection drug use and injection equipment sharing following HCV treatment in a randomized trial comparing peer-assisted telemedicine for HCV treatment (TeleHCV) versus peer-assisted usual care in rural PWUD. We hypothesize that TeleHCV reduces risky behaviors and peers facilitate this change. We used mixed-effects logistic regression to describe participant-level (n = 203) associations between both injection drug use and injection equipment sharing and randomized groups, frequency of peer contact, HCV treatment initiation, HCV cure, and time. Risky behaviors were surveyed at baseline and 12 and 36 weeks after HCV treatment completion. Injection drug use declined more over time in TeleHCV participants vs. control at 12 weeks (adjusted odds ratio [aOR] = 0.42, 95% CI 0.20-0.87, p = 0.02) and 36 weeks (aOR = 0.48, 95% CI 0.21-1.08, p = 0.076). Injection drug use decreased more with a greater number of peer interactions, with reductions among participants in the 3rd quartile exceeding those in the 1st quartile of peer interactions at 12 weeks (aOR = 0.75, 95% CI 0.57-0.99, p = 0.04). Similarly, injection equipment sharing decreased over time, with reductions among participants in the 3rd quartile exceeding those in the 1st quartile of peer interactions at 36 weeks (aOR = 0.08, 95% CI 0.01-0.97, p = 0.047). Peer-assisted telemedicine for HCV treatment decreases injection drug use and injection equipment sharing; peers contribute to this effect.

Outbreaks in the Neonatal Intensive Care Unit: Description and Management.

Healthcare settings, especially intensive care units, can provide an ideal environment for the transmission of pathogens and the onset of outbreaks. Many factors can contribute to the onset of an epidemic in a neonatal intensive care unit (NICU), including neonates' vulnerability to healthcare-associated infections, especially for those born preterm; facility design; frequent invasive procedures; and frequent contact with healthcare personnel. Outbreaks in NICUs are one of the most relevant problems because they are often caused by multidrug-resistant organisms associated with increased mortality and morbidity. The prompt identification of an outbreak, the subsequent investigation to identify the source of infection, the risk factors, the reinforcement of routine infection control measures, and the implementation of additional control measures are essential elements to contain an epidemic.

Early life child protection contacts and developmental risk at age five: a whole-of-population cohort study of 479,413 children in two Australian states.

IntroductionChildren who experience maltreatment have worse health and development outcomes than other children. Early prevention relies on opportunities to respond to system contacts that reliably indicate the population burden of children’s future developmental risk. Objectives and ApproachWe quantified the population burden of developmental vulnerability at age five by the type, timing, and frequency of child protection contacts before school, among children in two Australian states. We used linked whole-population births, child protection and Australian Early Development Census (AEDC) data (2009-2018 cycles) in New South Wales (NSW) and South Australia (SA). Results56,650/398,702 (14%) NSW and 12,617/80,731 (16%) SA children had ≥1 child protection contacts before school. The risk of developmental vulnerability on ≥1 domains was lowest in the no child protection group (NSW, 17-18%; SA, 19%), with higher risks in the child protection report (NSW, 28-29%; SA, 32-35%) through to the OOHC (NSW, 35-38%; SA, 39-50%) groups, with a similar pattern for the risk of medically diagnosed conditions. Children with only one child protection report before school had a higher developmental risk than the no child protection group (NSW, 34% versus 21%; SA, 42% versus 24%). Conclusions/ImplicationsEven a single child protection report in the first 2000 days of children’s lives was a robust indicator of developmental risk at age five, with higher developmental risks among children with more serious child protection contacts before school. Child protection reports represent an under-utilised asset to inform early universal and targeted support from health, human and early education services.

Exploring the Relations Among Knowledge, Contact, and Transgender Prejudice

AbstractOver the last few years there has been an increase in anti-trans rhetoric and violence towards transgender individuals, the consequences of which continue to adversely affect transgender people’s lives. Given these societal ramifications, it is crucial to explore how transprejudice (prejudice against transgender people) might be ameliorated. Research within social psychology has repeatedly shown intergroup contact to reduce various forms of outgroup prejudice, but little extant research has tested this association for prejudice related to transgender identity. We conducted three cross-sectional studies which tested the relation between contact (quantity and quality) with transgender people, trans-related knowledge (i.e., participants’ self-reported level of knowledge about experiences of transgender people), and transprejudice (cognitive and affective). Across the three studies, we found that contact quantity and contact quality significantly mediated the negative relationship between knowledge and transprejudice (although contact quality was a more consistent mediator). Those with more trans-related knowledge had more frequent and better-quality contact with trans people, and in turn showed less prejudice towards transgender people. We found less consistent support for an alternative mediation model with prior knowledge mediating the contact to transprejudice link. These findings demonstrate the importance of the role of both knowledge about and contact with transgender people as a means of transprejudice reduction, with wide-reaching implications for creating environments that are diverse, equitable, and inclusive.

The most common dermatoses of athletes

Introduction and purpose The skin and subcutaneous tissue constitute the body's protective barrier. It also fulfills important physiological functions. It protects internal organs against the harmful effects of environmental factors and maintains the balance between the human body and the environment. Athlete's dermatoses are a wide group of skin diseases that may occur as a result of specific conditions to which people who practise sports are exposed. Some skin diseases are characteristic of specific sports, while others may occur regardless of the type of physical activity performed. Mechanical damage to the epidermis, excessive humidity, contact with pathogens and exposure to various environmental factors play a key role in the development of these diseases. Regular dermatological check-ups are crucial for identifying and treating skin lesions and preventing mass infections caused by infectious agents. The study discusses the most common dermatoses in athletes, including fungal, bacterial and viral infections, contact dermatitis and dermatoses caused by mechanical and environmental factors. Materials and methods The literature included in the PubMed, BioMed Central and Polish Medical Platform databases is searched by means of the words such as dermatosis, sport, skin, fungal, bacterial, viral infection, contact dermatitis. Quoted sources in selected works were also used. ConclusionsMany factors can have a harmful effect on the skin, negatively affect its function as an integral barrier of the body and, consequently, cause the development of dermatoses, which are quite common among athletes due to frequent contact with sweat, clothing, sports equipment and the environments in which they train. Prevention is an important element in minimizing the risk of skin problems and this is key to maintaining health and continuing physical activity.

Application of the behaviour-centred design to understand facilitators and deterrents of hand hygiene among healthcare providers: findings from a formative phase of a cluster randomised trial in the Kampala Metropolitan area

BackgroundHand hygiene is known to reduce healthcare-associated infections. However, it remains suboptimal among healthcare providers. In this study, we used the Behaviour-centered Design approach to explore the facilitators and deterrents to hand hygiene among healthcare providers in the Kampala Metropolitan area, Uganda.MethodsWe conducted a formative qualitative study as part of a cluster randomised trial in 19 healthcare facilities (HCFs). The study used 19 semi-structured and 18 key informant interviews to collect data on hand hygiene status and facilitators and deterrents of hand hygiene. Research assistants transcribed verbatim and used a thematic framework aided by Nvivo 14.0. to undertake analysis. We used thick descriptions and illustrative quotes to enhance the credibility and trustworthiness of our findings.ResultsAbout 47.4% of the HCFs had sufficient hand hygiene infrastructure, and 57.9% did not report total compliance with hand hygiene during patient care. The physical facilitator for hand hygiene was the presence of constant reminders such as nudges, while the biological included the frequency of patient contact and the nature of clinical work. The only biological deterrent was the heavy workload in HCFs. The executive brain facilitators included knowledge of workplace health risks, infection prevention and control (IPC) guidelines, and a positive attitude. A negative attitude was the executive brain deterrent to hand hygiene. Recognition, rewards, and fear of infections were the only motivated brain facilitators. Behavioural setting facilitators included proximity to functional hand hygiene infrastructure, the existence of active IPC committees, good leadership, and the availability of a budget for hand hygiene supplies. Behavioural setting deterrents included the non-functionality and non-proximity to hand hygiene infrastructure and inadequate supplies.ConclusionsThe study revealed low compliance with hand hygiene during the critical moments of patient care and inadequacy of hand hygiene infrastructure. The deterrents to hand hygiene included a heavy workload, negative attitude, inadequate supplies, non-functionality, and long distance to hand washing stations. Facilitators included constant reminders, fear of infections, frequency of patient contact and nature of clinical work, positive attitude, knowledge of IPC guidelines, recognition and reward, good leadership, availability of budgets for hand hygiene supplies, availability and proximity to hand hygiene supplies and infrastructure and active IPC committees.Trial registrationISRCTN Registry with number ISRCTN98148144.

Social relationship factors, depressive symptoms, and incident dementia: a prospective cohort study into their interrelatedness.

Different aspects of social relationships (e.g., social network size or loneliness) have been associated with dementia risk, while their overlap and potentially underlying pathways remain largely unexplored. This study therefore aimed to (1) discriminate between different facets of social relationships by means of factor analysis, (2) examine their associations with dementia risk, and (3) assess mediation by depressive symptoms. Thirty-six items from questionnaires on social relationships administered in Wave 2 (2004/2005) of the English Longitudinal Study of Ageing (n = 7536) were used for exploratory and confirmatory factor analysis. Factors were then used as predictors in Cox proportional hazard models with dementia until Wave 9 as outcome, adjusted for demographics and cardiovascular risk factors. Structural equation modeling tested mediation by depressive symptoms through effect decomposition. Factor analyses identified six social factors. Across a median follow-up time of 11.8 years (IQR = 5.9-13.9 years), 501 people developed dementia. Higher factor scores for frequency and quality of contact with children (HR = 0.88; p = 0.021) and more frequent social activity engagement (HR = 0.84; p < 0.001) were associated with lower dementia risk. Likewise, higher factor scores for loneliness (HR = 1.13; p = 0.011) and negative experiences of social support (HR = 1.10; p = 0.047) were associated with higher dementia risk. Mediation analyses showed a significant partial effect mediation by depressive symptoms for all four factors. Additional analyses provided little evidence for reverse causation. Frequency and quality of social contacts, social activity engagement, and feelings of loneliness are associated with dementia risk and might be suitable targets for dementia prevention programs, partly by lowering depressive symptoms.

State of infection prevention knowledge among healthcare professionals in Japan: a questionnaire survey analysis using text mining

Healthcare-associated infections (HAIs) are an important issue that needs to be continuously addressed in healthcare institutions, and healthcare professionals (HCPs) are expected to strengthen educational programmes on infection prevention. Although the incidence of HAIs in Japan has been decreasing, the actual state of knowledge on infection prevention among HCPs remains unclear. To clarify the actual infection prevention knowledge of HCPs in Japan. The study participants were 1158 HCPs working in healthcare institutions with frequent contact with patients (283 doctors, 591 nurses, 115 physical therapists, 97 radiologists, and 72 medical technologists). HCPs described the infection prevention behaviours they consciously adhered to via an online self-administered questionnaire. Data were analysed by text mining. Categories were extracted from the responses to reveal HCPs' infection prevention knowledge. More than half of the participants (64.9%) were aged > 40 years, and 48.1% had over 20 years of clinical experience. The majority of the participants were nurses (51.0%), 43.9% had a bachelor's degree, and 56.6% were female. Seven categories regarding infection prevention knowledge were extracted: "performing hand hygiene and gargling," "wearing personal protective equipment," "strengthening one's immunity," "protecting oneself and patients from infection," "distinguishing clean and unclean zones," "actions to prevent transmission to others in daily life activities," and "maintaining distance from others." These results suggest that most HCPs working in healthcare settings in Japan prioritize and adhere to standard precautionary measures, and that the low incidence of HAIs may be influenced by perceptions of the knowledge of "handwashing and gargling" among HCPs.

BLOOD LEAD CONCENTRATION ANALYSIS BETWEEN REHABILITATION FACILITY AND PERI-URBAN ENVIRONMENT VIRGINIA OPOSSUMS (DIDELPHIS VIRGINIANA) OF ILLINOIS.

The Virginia opossum (Didelphis virginiana) is the only marsupial in North America with a natural range north of Mexico. Its range is widespread throughout the United States, including Illinois. Virginia opossums are opportunistic omnivores that will eat a variety of fruits, grains, insects, and even carrion. They are a ground-foraging species, with frequent soil contact allowing for potential exposure to heavy metal contaminants in terrestrial environments. They are also opportunists that thrive in human-altered ecosystems, including peri-urban environments. Lead is a naturally occurring element and highly toxic metal that is abundant in the soil, primarily due to anthropogenic factors such as fossil fuel use, paint, industrial production waste, and battery recycling. Furthermore, carrion and offal piles containing lead bullet fragments remaining from hunting result in environmental contamination of this heavy metal. Few studies exist on lead exposure in the Virginia opossum. This pilot study evaluates the blood lead burden of 16 free-ranging Virginia opossums presented to a wildlife rehabilitation facility, compared with 16 wild-caught Virginia opossums trapped in grassland, maintained forest, or mixed ecotones. In other species, lead toxicosis has been associated with cognitive dysfunction that may increase the likelihood of trauma or injury in a free-ranging setting. In addition, a high incidence of Virginia opossums presenting for wildlife rehabilitation do so as result of human-animal conflict. Therefore, it was anticipated that individuals presenting for wildlife rehabilitation would have significantly higher blood lead concentrations than their free-roaming counterparts. In this study, every Virginia opossum had measurable blood lead concentrations and the average blood lead concentration of the rehabilitated group was 2.7 times higher than that measured in wild-caught Virginia opossums. These results suggest that Virginia opossums are exposed and susceptible to lead toxicosis due to their diet and foraging behaviors, making them more prone to subsequent injury and presentation to wildlife rehabilitation centers.

Parent-teacher relationship and students' learning engagement in China: A longitudinal study considering urban-suburban differences.

The importance of parent-teacher relationships has been well-discussed in Western contexts. It's still unclear whether and how parent-teacher relationships affect students' academic development, especially in the context of China's uneven development between urban and suburban areas. This study examined the urban-suburban differences in the influence of the parent-teacher relationships on students' learning engagement during the last 3 years of primary school to contribute to related policy and practice. Data were collected annually during the summer period in three waves from Grades 4 to 6. The sample included 1408 students (Mage = 10.35, SD = .48; 49.1% boys) paired with their mothers (Mage = 38.82, SD = 3.54), with 643 pairs from urban areas and 765 pairs from suburban areas in China. In each wave, the parents reported the frequency of contact with their child's teacher during the previous school year as well as the quality of their relationship, and the students reported their learning engagement. Latent growth models were used to examine the hypotheses. A statistically significant decline in learning engagement was seen only in suburban students, while the parent-teacher relationships seemed to increase for both suburban and urban participants. Latent growth modelling showed that the increasing levels of relationship quality reduced the decline in the suburban students' learning engagement, although the contact between parents and teachers did not play such a positive role for both urban and suburban students. The findings reveal a compensatory effect of the quality of the parent-teacher relationship on suburban students' learning engagement. Considering the difference in students' learning engagement between urban and suburban students, increased effort on high-quality parent-teacher relationships for suburban students is required to better support their academic development.

Care coordinator delivered method of levels therapy to improve engagement and other outcomes in early psychosis (CAMEO): protocol for a feasibility cluster-randomised controlled trial

BackgroundRates of disengagement from early intervention in psychosis (EIP) services are high. Care coordinators make up the largest staff group in EIP services and have the most frequent and sustained contact with service users. The quality of relationships between service users and care coordinators plays a central role in determining the effectiveness of EIP services. Care coordinators, however, are not routinely offered training in psychosocial interventions that could enhance the therapeutic impact of their role. Method of levels (MOL) is a flexible, transdiagnostic cognitive therapy with potential advantages over previously evaluated approaches. Training care coordinators in MOL could make their routine contacts with service users more helpful and improve outcomes such as recovery rates and levels of engagement.AimsThis study aims to assess the feasibility of training care coordinators in EIP services to deliver MOL, to understand whether this approach might improve service user engagement and recovery from psychosis compared to treatment as usual, and to assess the feasibility of conducting a cluster-randomised controlled trial (C-RCT) with clustering at the level of teams. Specific feasibility outcomes relate to the recruitment and retention of participants, care coordinators’ level of engagement with the MOL training and supervision programme, implementation of MOL in practice, and the acceptability of the intervention amongst participants.MethodsA feasibility parallel group cluster-randomised controlled trial (C-RCT) designs with two arms: (1) treatment as usual (TAU) or (2) TAU plus support from a care coordinator who has received training in MOL. Randomisation will take place at the level of EIP teams with an allocation ratio of 1:2 in favour of the intervention arm. Our recruitment target is 12 EIP teams, 24 care coordinators working in participating EIP teams, and up to 96 service users working with participating care coordinators. Outcomes will be collected at baseline, 3 months, and 6 months. Qualitative methods will be used to understand participants’ experiences of the study, MOL training programme, and MOL intervention.DiscussionThis is the first study that aims to evaluate the feasibility of training EIP care coordinators to deliver MOL in their routine practice. Training care coordinators in MOL could enhance the quality of relationships between care coordinators and service users and improve outcomes for people experiencing early psychosis. Results will be used to determine the appropriateness of progressing to a larger evaluation trial.Trial registrationThis study was prospectively registered with the ISRCTN Registry (14082421).

Observational study of close contact behaviors in a multinational graduate student office

Understanding human contact behavior plays a crucial role in improving the design of indoor environments, for example, by enhancing thermal comfort, workplace performance and productivity, and controlling infection transmission. Although baseline information for indoor environmental design is available, data on person-to-person contact behavior are limited, especially in populations of diverse nationalities, genders, and age ranges. In this study, we used high-resolution video cameras to collect close contact data for five consecutive school days in a multinational graduate school student office in Japan with a reserved cultural background. We characterized human close-contact behavior using stochastic interactions in terms of interpersonal distance, assortativity, posture, duration, and frequency of contact in a multinational population. Our results showed a remarkable difference compared to the study results from person-to-person contact behavior in an ethnically homogenous population. The interpersonal distance averaged 0.75 m, and the close contact frequency was notably lower, but the close contact duration was significantly longer. Nationality showed stronger homophily. We considered the degree centrality measures of the nodes in the observed networks. The observed contact network links were dense with high reciprocity. High contact heterogeneity was observed in twenty-five percent of the nodes. These data can be used to improve targeted epidemiological analyses for indoor occupant health decision-making, and infection spread prevention strategies.

Stigma toward individuals with intellectual disabilities and severe mental disorders: analysis of postgraduate university students’ perceptions

PurposeThe purpose of this study is to delve into societal stigma surrounding severe mental disorders and intellectual disabilities, emphasizing gender differences and students’ proximity influence.Design/methodology/approachInvolving 572 Spanish master’s students, this nonexperimental study categorizes participants based on contact frequency, using Goratu and CAEE questionnaires to measure stigma.FindingsGender-based stigma differences are absent; however, increased contact correlates with lower stigma levels. Notably, greater closeness is associated with more positive attitudes toward intellectual disability, resulting in diminished stigma toward severe mental disorders.Practical implicationsThis research sheds light on the pervasive stigma faced by individuals with intellectual disabilities and severe mental disorders among postgraduate university students. Notably, the recognition of widespread stigma among individuals with higher education highlights a more significant societal problem. The findings underscore the urgent need for targeted interventions, especially in higher education contexts, to enhance understanding and reduce societal bias.Social implicationsBy identifying factors influencing stigma and emphasizing the importance of contact in fostering empathy, the study lays the groundwork for informed socioeducational strategies. These strategies have the potential to promote inclusivity, challenge stereotypes and contribute to the well-being and social integration of those affected by intellectual disabilities and severe mental disorders.Originality/valueThe findings highlight the efficacy of direct contact in reducing stigma and underscore the necessity for nuanced understanding. The study suggests fostering positive attitudes through increased contact can combat prejudice and promote social inclusion. Nevertheless, further research is crucial to explore factors influencing stigma reduction and design comprehensive socioeducational interventions addressing diverse cultural proficiencies. This study contributes valuable insights for mitigating stigma, fostering inclusivity and informing future interventions.

Pemphigus vulgaris autoantibodies induce an ER stress response.

Desmosomes are intercellular junctions that mediate cell-cell adhesion and are essential for maintaining tissue integrity. Pemphigus vulgaris (PV) is an autoimmune epidermal blistering disease caused by autoantibodies (IgG) targeting desmoglein 3 (Dsg3), a desmosomal cadherin. PV autoantibodies cause desmosome disassembly and loss of cell-cell adhesion, but the molecular signaling pathways that regulate these processes are not fully understood. Using high-resolution time-lapse imaging of live keratinocytes, we found that ER tubules make frequent and persistent contacts with internalizing Dsg3 puncta in keratinocytes treated with PV patient IgG. Biochemical experiments demonstrated that PV IgG activated ER stress signaling pathways, including both IRE1⍺ and PERK pathways, in cultured keratinocytes. Further, ER stress transcripts were upregulated in PV patient skin. Pharmacological inhibition of ER stress protected against PV IgG-induced desmosome disruption and loss of keratinocyte cell-cell adhesion, suggesting that ER stress may be an important pathomechanism and therapeutically targetable pathway for PV treatment. These data support a model in which desmosome adhesion is integrated with ER function to serve as a cell adhesion stress sensor that is activated in blistering skin disease.

Effect of active loop extrusion on the two-contact correlations in the interphase chromosome.

The population-averaged contact maps generated by the chromosome conformation capture technique provide important information about the average frequency of contact between pairs of chromatin loci as a function of the genetic distance between them. However, these datasets do not tell us anything about the joint statistics of simultaneous contacts between genomic loci in individual cells. This kind of statistical information can be extracted using the single-cell Hi-C method, which is capable of detecting a large fraction of simultaneous contacts within a single cell, as well as through modern methods of fluorescent labeling and super-resolution imaging. Motivated by the prospect of the imminent availability of relevant experimental data, in this work, we theoretically model the joint statistics of pairs of contacts located along a line perpendicular to the main diagonal of the single-cell contact map. The analysis is performed within the framework of an ideal polymer model with quenched disorder of random loops, which, as previous studies have shown, allows us to take into account the influence of the loop extrusion process on the conformational properties of interphase chromatin.
