Prevention and control of venous thromboembolism after major orthopedic surgery through doctor-to-patient cultivation of musculoskeletal ability based on King's theory of goal attainment.

OBJECTIVES: To explore the prevention and management of venous thromboembolism (VTE) following major orthopaedic surgery (MOS) by fostering doctor-to-patient cultivation of musculoskeletal ability, guided by King's theory of goal attainment. METHODS: A cohort of patients (n = 116) undergoing MOS was selected for the study, and were divided into two groups: the regular group and the observation group, with patients in the regular group experiencing routine nursing care and management and those in the observation group undergoing musculoskeletal ability cultivation based on King's theory of goal attainment. Baseline data, limb vascular ultrasonography, coagulation function, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score, VTE prevention efficacy, Exercise of Self-care Ability Scale (ESCA) score, and nursing satisfaction were analysed comparatively. RESULTS: There was no significant within-group difference in baseline data (P > 0.05). Following the interventions, the observation group demonstrated statistically significant reductions in the Musculoskeletal-Integrated Imaging Score, various dimensions of WOMAC scores, and D-dimer (D-D) levels (P < 0.05) both in comparison to their levels before interventions and to those observed in the regular group (P < 0.05). Additionally, the observation group exhibited increases in prothrombin time levels and various dimensions of ESCA scores (P < 0.05) post-intervention, surpassing the pre-intervention levels and those obtained in the regular group (P < 0.05). Furthermore, the observation group exhibited a significantly lower incidence of VTE (P < 0.05) and higher nursing satisfaction (P < 0.05) compared to the regular group. CONCLUSIONS: Nursing intervention measures, utilizing doctor-to-patient cultivation of musculoskeletal ability based on King's theory of goal attainment, have demonstrated a significant clinical benefit for VTE prevention and control in post-MOS patients. This approach not only effectively prevented VTE in post MOS patients but also enhanced their satisfaction towards nursing care.

Polyphyllin VII alleviates pulmonary hypertension by inducing miR-205-5p to target the ß-catenin pathway.

OBJECTIVE: This study aims to investigate the impact of Polyphyllin VII (PP7) on pulmonary hypertension (PH) and elucidate the underlying mechanism involving microRNA (miR)-205-5p/ß-catenin. METHODS: The PH rat model was induced through hypoxia exposure. The effects of intraperitoneal injection of PP7 on pulmonary artery tissue pathology, hemodynamics, miR-205-5p expression and ß-catenin protein levels were assessed. In vitro, pulmonary arterial smooth muscle cells (PASMCs) were subjected to hypoxic conditions. Moreover, miR-205-5p and/or ß-catenin were overexpressed through transfection. PASMCs were pre-cultured in 20 µM PP7, and subsequent measurements included proliferation, apoptosis and vascular remodeling protein expression. RESULTS: PP7 ameliorated PH symptoms in rats, upregulated miR-205-5p expression and inhibited ß-catenin protein expression. Furthermore, miR-205-5p upregulation inhibited ß-catenin expression in PASMCs. The overexpression of ß-catenin aggravated hypoxia-induced proliferation, inhibited apoptosis and further augmented VEGF and α-SMA protein expression. Additionally, miR-205-5p overexpression alleviated the hypoxia-induced PASMC proliferation and apoptosis by inhibiting ß-catenin protein expression. Under hypoxic conditions, PP7 significantly elevated miR-205-5p while downregulating ß-catenin protein expression. Furthermore, inhibiting miR-205-5p counteracted the inhibitory effect of PP7 on ß-catenin, consequently blocking the regulatory role of PP7 in PASMC proliferation and apoptosis. CONCLUSION: PP7 likely modulates ß-catenin protein levels by promoting miR-205-5p expression, thereby alleviating PH, vascular remodeling and airway smooth muscle remodeling.

Faces synchronize when communication through spoken language is prevented.

Cooperating with another person requires communicating intentions and coordinating behavior. People often accomplish these tasks using spoken language, but verbal communication is not always available. Here, we test the hypothesis that, to establish successful cooperative interaction, people compensate for the temporary loss of one means, verbal communication, by amplifying another, namely nonverbal expressive synchrony. Fifty-seven female dyads, half of whom were prevented from using spoken language, completed four cooperative tasks, two of which induced expressions of emotion, while their faces were filmed. The no-language dyads displayed more facial-expressive synchrony, quantified using a novel application of multidimensional dynamic time warping. We find that solutions to coordinating interaction solved by spoken language can be compensated for by synchronizing facial expressions. The findings also point to one social force-the lack of shared language-that might, in the long-term, select for cultures of increased nonverbal expressiveness and synchrony.

Wearing N95, Surgical, and Cloth Face Masks Compromises the Perception of Emotion.

According to the familiar axiom, the eyes are the window to the soul. However, wearing masks to prevent the spread of viruses such as COVID-19 involves obscuring a large portion of the face. Do the eyes carry sufficient information to allow for the accurate perception of emotions in dynamic expressions obscured by masks? What about the perception of the meanings of specific smiles? We addressed these questions in two studies. In the first, participants saw dynamic expressions of happiness, disgust, anger, and surprise that were covered by N95, surgical, or cloth masks or were uncovered and rated the extent to which the expressions conveyed each of the same four emotions. Across conditions, participants perceived significantly lower levels of the expressed (target) emotion in masked faces, and this was particularly true for expressions composed of more facial action in the lower part of the face. Higher levels of other (non-target) emotions were also perceived in masked expressions. In the second study, participants rated the extent to which three categories of smiles (reward, affiliation, and dominance) conveyed positive feelings, reassurance, and superiority, respectively. Masked smiles communicated less of the target signal than unmasked smiles, but not more of other possible signals. The present work extends recent studies of the effects of masked faces on the perception of emotion in its novel use of dynamic facial expressions (as opposed to still images) and the investigation of different types of smiles.

Designing evidence-based support aids for social media access for individuals with moderate-severe traumatic brain injury: A preliminary acceptability study.

Background: Adults with traumatic brain injury (TBI) report significant barriers to using current social media platforms, including cognitive overload and challenges in interpreting social cues. Rehabilitation providers may be tasked with helping to address these barriers. Objectives: To develop technological supports to increase social media accessibility for people with TBI-related cognitive impairments and to obtain preliminary data on the perceived acceptability, ease of use, and utility of proposed technology aids. Methods: We identified four major barriers to social media use among individuals with TBI: sensory overload, memory impairments, misreading of social cues, and a lack of confidence to actively engage on social media platforms. We describe the process of developing prototypes of support aids aimed at reducing these specific social media barriers. We created mock-ups of these prototypes and asked 46 community-dwelling adults with TBI (24 females) to rate the proposed aids in terms of their acceptability, ease of use, and utility. Results: Across all aids, nearly one-third of respondents agreed they would use the proposed aids frequently, and the majority of respondents rated the proposed aids as easy to use. Respondents indicated that they would be more likely to use the memory and post-writing aids than the attention and social cue interpretation aids. Conclusions: Findings provide initial support for social-media-specific technology aids to support social media access and social participation for adults with TBI. Results from this study have design implications for future development of evidence-based social media support aids. Future work should develop and deploy such aids and investigate user experience.

Computer-Mediated Communication in Adults With and Without Moderate-to-Severe Traumatic Brain Injury: Survey of Social Media Use.

BACKGROUND: Individuals with a history of traumatic brain injury (TBI) report fewer social contacts, less social participation, and more social isolation than noninjured peers. Cognitive-communication disabilities may prevent individuals with TBI from accessing the opportunities for social connection afforded by computer-mediated communication, as individuals with TBI report lower overall usage of social media than noninjured peers and substantial challenges with accessibility and usability. Although adaptations for individuals with motor and sensory impairments exist to support social media use, there have been no parallel advances to support individuals with cognitive disabilities, such as those exhibited by some people with TBI. In this study, we take a preliminary step in the development process by learning more about patterns of social media use in individuals with TBI as well as their input and priorities for developing social media adaptations. OBJECTIVE: This study aims to characterize how and why adults with TBI use social media and computer-mediated communication platforms, to evaluate changes in computer-mediated communication after brain injury, and to elicit suggestions from individuals with TBI to improve access to social media after injury. METHODS: We conducted a web-based survey of 53 individuals with a chronic history of moderate-to-severe TBI and a demographically matched group of 51 noninjured comparison peers. RESULTS: More than 90% of participants in both groups had an account on at least one computer-mediated communication platform, with Facebook and Facebook Messenger being the most popular platforms in both groups. Participants with and without a history of TBI reported that they use Facebook more passively than actively and reported that they most frequently maintain web-based relationships with close friends and family members. However, participants with TBI reported less frequently than noninjured comparison participants that they use synchronous videoconferencing platforms, are connected with acquaintances on the web, or use social media as a gateway for offline social connection (eg, to find events). Of the participants with TBI, 23% (12/53) reported a change in their patterns of social media use caused by brain injury and listed concerns about accessibility, safety, and usability as major barriers. CONCLUSIONS: Although individuals with TBI maintain social media accounts to the same extent as healthy comparisons, some may not use them in a way that promotes social connection. Thus, it is important to design social media adaptations that address the needs and priorities of individuals with TBI, so they can also reap the benefits of social connectedness offered by these platforms. By considering computer-mediated communication as part of individuals' broader social health, we may be able to increase web-based participation in a way that is meaningful, positive, and beneficial to broader social life.

Evidence for Distinct Facial Signals of Reward, Affiliation, and Dominance from Both Perception and Production Tasks.

Smiles are nonverbal signals that convey social information and influence the social behavior of recipients, but the precise form and social function of a smile can be variable. In previous work, we have proposed that there are at least three physically distinct types of smiles associated with specific social functions: reward smiles signal positive affect and reinforce desired behavior; affiliation smiles signal non-threat and promote peaceful social interactions; dominance smiles signal feelings of superiority and are used to negotiate status hierarchies. The present work advances the science of the smile by addressing a number of questions that directly arise from this smile typology. What do perceivers think when they see each type of smile (Study 1)? How do perceivers behave in response to each type of smile (Study 2)? Do people produce three physically distinct smiles in response to contexts related to each of the three social functions of smiles (Study 3)? We then use an online machine learning platform to uncover the labels that lay people use to conceptualize the smile of affiliation, which is a smile that serves its social function but lacks a corresponding lay concept. Taken together, the present findings support the conclusion that reward, affiliation, and dominance smiles are distinct signals with specific social functions. These findings challenge the traditional assumption that smiles merely convey whether and to what extent a smiler is happy and demonstrate the utility of a social-functional approach to the study of facial expression.

Exploring the Relationship Between Fiction Reading and Emotion Recognition.

Fiction reading experience affects emotion recognition abilities, yet the causal link remains underspecified. Current theory suggests fiction reading promotes the simulation of fictional minds, which supports emotion recognition skills. We examine the extent to which contextualized statistical experience with emotion category labels in language is associated with emotion recognition. Using corpus analyses, we demonstrate fiction texts reliably use emotion category labels in an emotive sense (e.g., cry of relief), whereas other genres often use alternative senses (e.g., hurricane relief fund). Furthermore, fiction texts were shown to be a particularly reliable source of information about complex emotions. The extent to which these patterns affect human emotion concepts was analyzed in two behavioral experiments. In experiment 1 (n = 134), experience with fiction text predicted recognition of emotions employed in an emotive sense in fiction texts. In experiment 2 (n = 387), fiction reading experience predicted emotion recognition abilities, overall. These results suggest that long-term language experience, and fiction reading, in particular, supports emotion concepts through exposure to these emotions in context.

Regulation of circular RNAs act as ceRNA in a hypoxic pulmonary hypertension rat model.

To explore potential critical genes and identify circular RNAs (circRNAs) that act as the competitive endogenous RNA (ceRNA) in a hypoxic pulmonary hypertension (HPH) rat model. Constructed rat model, and a bioinformatics method was used to analyse differentially expressed (DE) genes and construct a circRNA-miRNA-mRNA ceRNA regulatory network. Then, qRT-PCR was used to verify. The significant DEcircRNAs/DEmiRNAs/DEmRNAs was showed, and a ceRNA network with 8 DEcircRNAs, 9 DEmiRNAs and 46 DEmRNAs were constructed. The functional enrichment suggested the inflammatory response, NF-κB signalling, MAPK cascade and Toll-like receptor were associated with HPH. Further assessment confirmed that circ_002723, circ_008021, circ_016925 and circ_020581 could have a potential ceRNA mechanism by sponging miR-23a or miR-21 to control downstream target gene and be involved in the pathophysiology of HPH. The qRT-PCR validation results were consistent with the RNA-Seq results. This study revealed potentially important genes, pathways and ceRNA regulatory networks in HPH.

PDGF mediates pulmonary arterial smooth muscle cell proliferation and migration by regulating NFATc2.

The reconstruction of pulmonary vascular structure caused by the proliferation and migration of pulmonary arterial smooth muscle cells (PASMCs) is the central link in the formation of pulmonary arterial hypertension (PAH). Platelet­derived growth factor (PDGF) can regulate the proliferation and migration of PASMCs. At the same time, nuclear factor of activated T cells (NFATs) plays an important role in the development of PAH. To the best of our knowledge, there are no reports yet regarding whether PDGF regulates NFATc2 to increase the proliferation of PASMCs. The present study aimed to investigate whether PDGF affects the proliferation and migration of PASMCs by regulating NFAT, and to study the pathogenesis of PAH. PASMCs were treated with recombinant PDGF; Cell Counting Kit­8 and clone formation experiments showed that PDGF enhanced the cell viability and proliferation of PASMCs. Cell cycle distribution and molecular markers related to cell proliferation (cyclin D1, CDK4 and Proliferating Cell Nuclear Antigen) were detected by flow cytometry, and the results indicated that PDGF promoted the division of PAMSCs. The scratch migration and Transwell migration assays showed that the migratory ability of PASMCs was enhanced following PDGF treatment. Changes in NFATs (NFATc1­5) after PDGF treatment were evaluated by reverse transcription­quantitative PCR and western blotting; NFATc2 showed the most significant results. Finally, PDGF­treated cells were treated with an NFAT pathway inhibitor, cyclosporin A, or a small interfering RNA targeting NFATc2, and changes in cell proliferation and migration were evaluated to assess the role of NFATc2 in PDGF­induced cell proliferation and migration. In conclusion, PDGF may regulate PASMC proliferation and migration by regulating the expression of NFAT, further leading to the occurrence of PAH. It is proposed that NFATc2 could be used as a potential target for PAH treatment.

Neural responses to intention and benefit appraisal are critical in distinguishing gratitude and joy.

Gratitude and joy are critical for promoting well-being. However, the differences between the two emotions and corresponding neural correlates are not understood. Here we addressed these issues by eliciting the two emotions using the same stimuli in an fMRI task. In this help reception task, participants imagined them in a situation where they need financial aid. Critically, we manipulated the benefactor's intention to provide help and the value of the benefit. Behaviorally, gratitude was stronger than joy when the benefactor-intention was strong and the benefit-value was low compared to other conditions. In parallel, gratitude activated mentalizing-related (e.g. precuneus) and reward-related regions (e.g. putamen) more strongly than joy in corresponding conditions compared to others. Moreover, gratitude was more negatively (or less positively) encoded in the region associated with mentalizing (i.e. the left superior temporal gyrus) than joy. Multivariate pattern analysis further demonstrated that the modulation patterns of benefactor-intention and benefit-value in mentalizing-related (e.g. precuneus, temporo-parietal junction) and reward-related regions (e.g. putamen, perigenual anterior cingulate/ventromedial prefrontal cortex) could distinguish the two emotions. The findings suggest that benefactor-intention and benefit-value appraisal and their neural correlates are critical in distinguishing gratitude and joy. Direct implications for gratitude interventions were discussed.

Historical Migration Patterns Shape Contemporary Cultures of Emotion.

Human emotional behavior varies across cultures. Smiling at a passing stranger on the street may seem perfectly normal in one culture and profoundly strange or even suspicious in another. What are the origins of cultural differences in emotional expression, communication, and regulation? We review new evidence in favor of one answer to this question. A socioecological factor, historical heterogeneity-defined as the ancestral diversity of the world's regions based on human migration patterns over centuries-accounts for important cultural variations in emotional experience and expression. We summarize findings from studies of large global samples that link the migratory history of a country's population with present-day cultural differences in how overtly and clearly emotions are expressed to others, in the frequency and meaning of smiles, and in associated character traits. New research also extends the analysis to the historical heterogeneity of the United States, and country-level findings are replicated at the level of the states. We suggest that enduring emotional behaviors and traits evolve from the opportunities and challenges posed by the commingling of people of diverse ancestries. We conclude by highlighting the questions and challenges for future research stemming from this approach.

Autophagy in pulmonary hypertension: Emerging roles and therapeutic implications.

Autophagy is an important mechanism for cellular self-digestion and basal homeostasis. This gene- and modulator-regulated pathway is conserved in cells. Recently, several studies have shown that autophagic dysfunction is associated with pulmonary hypertension (PH). However, the relationship between autophagy and PH remains controversial. In this review, we mainly introduce the effects of autophagy-related genes and some regulatory molecules on PH and the relationship between autophagy and PH under the conditions of hypoxia, monocrotaline injection, thromboembolic stress, oxidative stress, and other drugs and toxins. The effects of other autophagy-related drugs, such as chloroquine, 3-methyladenine, rapamycin, and other potential therapeutic drugs and targets, in PH are also described.

Serum cardiac troponin elevation predicts mortality in patients with pulmonary hypertension: A meta-analysis of eight cohort studies.

OBJECTIVE: To determine the association of serum cardiac troponin (cTn) with the mortality of pulmonary hypertension (PH) patients via a meta-analysis. DATE SOURCE: We searched PubMed and EMBASE from inception to October 25, 2017. STUDY SELECTION: The reference lists of the retrieved articles were also consulted. The Q test and I2 test were used for to assess heterogeneity. The relationship between cTn elevation and mortality was analysed. Studies were stratified according to type of troponin (cTnT vs cTnI), region (Europe vs America) and follow-up length (≤3 years vs >3 years). RESULTS: Eight studies with 739 patients were included in the meta-analysis. Cardiac troponin elevation ranged from 14.3% to 94.5%. Overall, 48.8% (39/80) of patients with elevated cTn died compared to 18.6% (45/242) of patients with normal cTn levels. These findings showed cTn elevation was significantly related to an increased mortality risk in PH patients [hazard ratio (HR) = 3.05, 95% confidence interval (95% CI) = 2.16-4.32, I2  = 24.9%]. cTnI was better at predicting mortality than cTnT (HR = 3.37, 95%CI = 2.05-5.55 vs HR = 2.80, 95%CI = 1.97-3.98, respectively). American populations had increased mortality compared to European populations (HR = 4.23, 95%CI = 2.29-7.80 vs HR = 2.70, 95% CI = 1.95-3.74, respectively). This finding was independent of the follow-up length of the studies (≤3 years: HR = 2.36, 95%CI = 1.65-3.38; >3 years: HR = 4.55, 95%CI = 2.80-7.39). CONCLUSIONS: Although different studies detected the expression cTnT or cTnI by various methods, the mortality in the cTn-positive group was higher than that in the cTn-negative group. Serum cTn elevation emerged as an independent predictor of increased risk of mortality in PH patients.

Heterogeneity of long-history migration predicts smiling, laughter and positive emotion across the globe and within the United States.

Recent findings demonstrate that heterogeneity of long-history migration predicts present-day emotion behaviors and norms. Residents of countries characterized by high ancestral diversity display emotion expressions that are easier to decode by observers, endorse norms of higher emotion expressivity, and smile more in response to certain stimuli than residents of countries that lack ancestral diversity. We build on the extant findings and investigate historical heterogeneity as a predictor of daily smiling, laughter, and positive emotion across the world's countries and the states of the United States. Study 1 finds that historical heterogeneity is positively associated with self-reports of smiling, laughter, and positive emotions in the Gallup World Poll when controlling for GDP and present-day population diversity. Study 2 extends the findings to effects of long-history migration within the United States. We estimated the average percentage of foreign-born citizens in each state between 1850 and 2010 based on US Census information as an indicator of historical heterogeneity. Consistent with the world findings of Study 1, historical heterogeneity predicted smiling, laughter, and positive, but not negative, emotion. The relationships remained significant when controlling for per capita income and present-day population diversity of each state. Together, the findings further demonstrate the important role of long-history migration in shaping emotion cultures of countries and states, which persist beyond the original socio-ecological conditions, and open promising avenues for cross-cultural research.
