Understanding Motivations for Dating App Use Among Gay and Bisexual Men: Validation, Latent Profile Analysis, and Differences in Health Outcomes.

While there has been a proliferation in gay dating app (GDA) use in China, research into their potential effects on health outcomes, particularly mental health outcomes, among gay and bisexual men is lacking. The motivations for GDA use are diverse, and understanding users' motivation profiles may provide a necessary starting point for exploring the heterogeneous effects of GDA use on health outcomes. A cross-sectional survey of the motivations for GDA use and other health outcome variables (i.e., condom use frequency, self-stigma, and subjective emptiness) was conducted among 366 Chinese gay and bisexual men. The results of exploration structure equation modeling indicate that the GDA Use Motivation Scale, with a four-factor first-order model, had strong psychometric properties. Then, latent profile analysis (LPA) based on the mean scores of four aspects of motivation was performed. The results of the LPA revealed the existence of four profiles: "Weak motivations" (30.9%), "Differentiated motivations" (17.8%), "Moderate motivations" (30.3%), and "Strong motivations" (21.0%). Differences in health outcomes among the motivation profiles were found by using the Bolck-Croon-Hagenaars approach. Overall, most participants (60.1%) tended to use condoms consistently, regardless of how strong their GDA use motivation was; however, stronger GDA use motivations were associated with higher levels of self-stigma and subjective emptiness. We call for more research to focus on the real needs behind and motivations for GDA use so that all such app users' voices can be heard, as well as to raise awareness about the potential health risks associated with GDA use among Chinese gay and bisexual men.

The mechanism of Qingwen Gupi decoction on pulmonary fibrosis based on metabolomics and intestinal flora.

AIMS: To evaluate the effects of the Qingwen Gupi decoction (QGT) in a rat model of bleomycin-induced pulmonary fibrosis (PF), and explore the underlying mechanisms by integrating UPLC-Q-TOF/MS metabolomics and 16S rDNA sequencing of gut microbiota. METHODS AND RESULTS: The animals were randomly divided into the control, PF model, pirfenidone-treated, and low-, medium-, and high-dose QGT groups. The lung tissues were examined and the expression of TGF-ß, SMAD-3, and SMAD-7 mRNAs in the lung tissues were analyzed. Metabolomic profiles were analyzed by UPLC-QTOF/MS, and the intestinal flora were examined by prokaryotic 16 rDNA sequencing. Pathological examination and biochemical indices revealed that QGT treatment improved the symptoms of PF by varying degrees. Furthermore, QGT significantly downregulated TGF-ß1 and Smad-3 mRNAs and increased the expression levels of Smad-7. QGT-L in particular increased the levels of 18 key metabolic biomarkers that were associated with nine gut microbial species and may exert antifibrosis effects through arachidonic acid metabolism, glycerophospholipid metabolism, and phenylalanine metabolism. CONCLUSIONS: QGT alleviated PF in a rat model through its anti-inflammatory, antioxidant, and anti-fibrotic effects, and by reversing bleomycin-induced gut dysbiosis.This study lays the foundation for further research on the pathological mechanisms of PF and the development of new drug candidates.

The Online Strength-Informed Acceptance and Commitment Therapy Among COVID-19-Affected Adolescents.

Purpose: This study develops and investigates the changes in anxiety symptoms and quality of life (QoL) among participants of the online Strength-informed Acceptance and Commitment Therapy (SACT) across three tests. METHODS: A small-scale, quasi-experiment with no control group was conducted. Repeated-measures analysis was employed to assess the changes of the three tests, which were the pre-experimental, post-test, and 3-month follow-up test. A total of 47 adolescents (ages 10-12) completed the 45-min intervention that lasted 10 weeks. RESULTS: Compared with the pre-experimental, the post-test indicated significant anxiety symptoms reduction but not a statistically significant increase in QoL. The 3-month follow-up test indicated reduced anxiety symptoms and improved QoL compared with the pre-experimental. The with-in subject changes were substantial. CONCLUSIONS: The online SACT is a promising model to reduce anxiety symptoms and promote QoL among adolescents during the current COVID-19 pandemic, which show both short- and long-term benefit to the participants.

Development of a Three-Stage Strength-Based Meaning Intervention to Promote Mental Health Among Individuals with Physical Disabilities in Disadvantaged Communities: A Randomized Controlled Trial.

A three-stage strength-based meaning intervention (SMI) was developed in the present study, and its utility in facilitating the mental health of individuals with physical disabilities in low-income communities was tested. A randomized controlled and single-blind trial was adopted. A total of 50 qualified participants (mean age = 42.12, standard deviation = 8.68; 48% males; 26 for the intervention group, 24 for the control group) completed the pre-intervention test, post-intervention test, and three-month follow-up test. No significant difference was observed between the two groups at pre-intervention assessment . After intervention, the results in terms of strength knowledge, strength use, sense of meaning in life and mental health showed a significant improvement in the intervention group, with the changes maintained over three months except mental health. The differences in mental health between the post-intervention test and the three-month follow-up test were not significant in the intervention group. The results imply that the SMI model is a promising approach in promoting the mental health of individuals with physical disabilities in low-income communities as it promotes improved knowledge and use of strength and sense of meaning in life.

Optimal movement behaviors: correlates and associations with anxiety symptoms among Chinese university students.

BACKGROUND: The Canadian 24-Hour Movement Guidelines for Adults was released in 2020. There is a dearth of evidence on the association between adherence to the 24 h movement guidelines and health indicators. This study aims to (a) explore the associations between potential correlates and meeting the 24 h movement guidelines using a sample of Chinese university students; and (b) examine if meeting 24 h movement guidelines is associated with the severity of anxiety symptoms. METHODS: Cross-sectional findings are based on 1846 Chinese university students (mean age = 20.7 years, 64.0% female). Movement behaviors (physical activity, sedentary behavior, and sleep duration), possible correlates, and anxiety symptoms were measured through self-reported online questionnaires. Logistic regression models were performed to examine the associations. RESULTS: We found that male students and those who had a mother with a master's degree or above, more close friends and higher perceived family affluence were more likely to meet the overall 24 h guidelines. Meeting all 24 h movement guidelines presented the lower odds for severe anxiety symptoms than those meeting fewer recommendations in the 24 h movement guidelines. CONCLUSIONS: As one of the first to examine the correlates of adherence to the 24 h movement guidelines and the relationship between anxiety symptoms and meeting the guidelines among Chinese university students, our findings contribute to the growing body of evidence linking movement behaviors, psychosocial correlates, and heath indicators. Schools and health providers can encourage movement behaviors that follow the guidelines on campus.

A brief measure of perceived courtesy and affiliate stigma on COVID-19: A study with a sample from China.

The present study aimed to assist public health efforts by developing and conducting psychometric testing of a brief measure of COVID-19-related stigma among people who were potentially but not necessarily infected. All the items were generated and selected based on extensive literature review, participant interviews, and expert evaluations. The psychometric properties were evaluated through performing confirmatory factor analysis tests, exploration structure equation modeling, measurement invariance, internal consistency coefficient, composite reliability, and criterion-related validity, using a sample of 2812 adults (600 male, 2212 female; mean age = 37.23, SD = 6.17) from Hubei Province, China. A clear two-factor structure of the COVID-19-related stigma among people who were potentially but not necessarily infected (i.e., perceived courtesy and affiliate stigma) was identified through the literature review and interviews. Results suggest that the two-factor model of COVID-19-related stigma (5 items for each factor) model fit the data, and the psychometric properties were acceptable. Measurement invariance across gender was supported. A two-factor 10-item scale was finally obtained.

Persistence and remission of depressive symptoms and psycho-social correlates in Chinese early adolescents.

BACKGROUND: This study aimed to investigate a one-year course of persistent/remitted depressive symptoms and associated demographic and psychosocial factors that predict persistent/remitted depressive symptoms in Chinese high school students. METHODS: One thousand five hundred forty-four Grade 7 students provided data for the first wave. Of the initially recruited students, 483 who were classified as depressed (CESD score ≥ 16) at baseline were then tracked and invited to fill in the questionnaire for a second time (Grade 8) after 1 year. Finally, 435 of them were successfully matched. RESULTS: Two hundred two (46.4%) of the subset categorized as depressed in the first survey (N = 435) remained with depressive symptoms, while 233 (53.6%) recovered from depression 1 year later. Having siblings, a lower level of positive youth development, non-intact family status, and poor family functioning at baseline significantly predicted a higher likelihood of persistent depression, while those with fathers having higher educational qualifications (bachelor's degree or higher) at baseline showed a significantly higher probability of remitting from depression. CONCLUSIONS: The findings indicated that the prevalence of persistent depressive symptoms was generally high, and promoting aspects of positive youth development and family functioning for adolescents could be promising in preventing or reducing these symptoms.

Measuring character strengths as possible protective factors against suicidal ideation in older Chinese adults: a cross-sectional study.

BACKGROUND: Suicide is a global issue among the elderly. The number of older people committing suicide is proliferating, and the elderly suicide rate is the highest among all age groups in China. A better understanding of the possible protective factors against suicidal ideation is necessary to facilitate prevention and intervention efforts. The objectives of the present study are threefold. First, this study aims to examine the psychometric properties of the three-dimensional inventory of character strengths (TICS) with a sample of older adults. Second, this study intends to investigate correlations among suicide ideation, wellbeing, and character strengths. Third, the study seeks to explore the possible protective roles of the three character strengths and wellbeing in explaining suicidal ideation among older adults. METHODS: A cross-sectional study comprising 308 older adults aged at least 50 years old from nursing homes was conducted. Four questionnaires, namely, the TICS, the Geriatric Suicide Ideation Scale-10 items, the Brief Inventory of Thriving, and the Satisfaction with Life Scale, were used. Exploratory structural equation modeling, intraclass correlation coefficients, partial correlations, and sets of hierarchical regressions were adopted to estimate and report the results. RESULTS: TICS could be used to assess the character strengths (i.e., caring, inquisitiveness, and self-control) among older adults with an acceptable goodness-of-fit (chi square = 157.30, df = 63, p < 0.001, CFI = 0.94, TLI = 0.90, RMSEA = 0.07, 90% CI = [0.06, 0.08]). Wellbeing and character strengths exhibited a negative association with suicidal ideation among older adults. Moreover, character strengths showed an independently cross-sectional relationship with suicidal ideation, explaining 65.1% of the variance of suicidal ideation after controlling for the wellbeing and demographics. CONCLUSION: This study indicated that character strengths were associated with low levels of suicidal ideation. Therefore, the protective factors against suicidal ideation among older adults should be given additional attention.

Dynamics of Phosphorus Content in the Water-Sediment Interface of Wetlands in a Mid-Temperature Steppe.

In order to reveal dynamics changes in phosphorus release from the sediments of wetlands in a mid-temperature steppe without external phosphorus input, the relationship between phosphorus content in the overlying water, sediment, and interstitial water was studied using the variables control method. The results showed that, during the incubation period, the content of total phosphorus in the overlying water and the content of total phosphorus in interstitial water both presented in the order of August > September > July. Furthermore, the correlation relationships between phosphorus content in the overlying water, total phosphorus in the interstitial water, and the ratios of sediment Olsen-P to total phosphorus in the interstitial water, indicated that Olsen-P might be a kind of release form of phosphorus - from the sediment to the overlying water of the wetlands in Hulunbeier steppe, without external phosphorus input.

[Proteomics and its application to determine mechanism of action of traditional Chinese medicine].

There is no doubt that the traditional Chinese medicine(TCM) is effective, practical and scientific after it was used for thousands of years. However, the mechanisms of action of many TCM are still unclear because of their multi-component, multi-target and multi-level features, which hinder the modernization and internationalization of the TCM. Proteomics is to analyze the composition and activity of intracellular proteins which are changing dynamically from a holistic perspective. It is consistent with the holistic and dynamic views of the TCM and brings about the hope of clarifying the mechanism of action of the TCM. In recent years, great progress has been made in the application of proteomics to determine the mechanism of the TCM. This article introduced the core technologies of proteomics and systematically summarized the applications of proteomics in the study of the mechanism of the Chinese medicinal formulae, single Chinese medicine and monomeric compounds from the TCM to provide innovative ideas and methods for reference.

Development and initial validation of a short three-dimensional inventory of character strengths.

PURPOSE: Character strength is described as a positive and organized pattern of emotions, thoughts, and behaviors. It serves as a schema that organizes categories of information toward the self, others, and the world, and provides the self-aware knowledge that facilitates the pursuit of goals, values, and ethical principles. Recent research has suggested that three reliable factors emerge from the measures of character strengths: caring, inquisitiveness, and self-control. The goal of this paper is to develop a psychometrically sound short measure of character strength. METHODS: The questions were addressed in two studies using two independent samples: a cross-cultural (i.e., 518 Asians and 556 Westerners) sample, and a cross-population (i.e., 175 community participants and 171 inpatients) sample in China. RESULTS: Findings from the exploratory and confirmatory factor analysis suggested a cross-cultural three-factor model of character strength that could be measured by the Three-dimensional Inventory of Character Strengths (TICS). A multigroup confirmatory factor analysis further indicated that the number of factors and factor loadings was invariant in the medical and community samples. This result indicated that the brief inventory could be applied to a medical context. Internal reliability, content validity, and predictive validity were good, although the predictive validity of the three character strengths for psychological symptoms in the medical sample was more modest than that in the community sample. CONCLUSIONS: TICS is expected to be used for screening populations at risk, and a tool to aid mental health professionals in group-based treatment/intervention planning. It also should be noted that this short inventory should be used with caution for individual decision making.

MicroRNA-873 (miRNA-873) inhibits glioblastoma tumorigenesis and metastasis by suppressing the expression of IGF2BP1.

Glioblastoma multiforme (GBM) is known as a highly malignant brain tumor with a poor prognosis, despite intensive research and clinical efforts. In this study, we observed that microRNA-873 (miR-873) was expressed at low levels in GBM and that the overexpression of miR-873 dramatically reduced the cell proliferation, migration, and invasion of GBM cells. Our further investigations of the inhibition mechanism indicated that miR-873 negatively affected the carcinogenesis and metastasis of GBM by down-regulating the expression of IGF2BP1, which stabilizes the mRNA transcripts of its target genes. These results demonstrate that miR-873 may constitute a potential target for GBM therapy.

Sexual Self-Identification Offsets and Self-Stigma Moderates: Expanding the Rejection-Identification Model to Examine Stigma's Effects on Well-Being Among Gay and Bisexual Men.

Gender and sexual minorities still face stigma-related stress from all areas of society. The rejection-identification model (RIM) proposes that some stigmatized individuals may respond to the negative effects of stigma on well-being by enhancing their self-identification. However, this does not apply to all gender and sexual minorities. Grounded in minority stress theory and the RIM, this study examined how stigma-related stressors (i.e. perceived stigma and self-stigma) and their associated mechanisms impact sexual self-identification and subjective well-being. A total of 366 Chinese gay and bisexual men were included in the study. The results showed that sexual self-identification, as a protective factor, mediated the association between perceived stigma and subjective well-being. Furthermore, the indirect effect of the mediation model was moderated by self-stigma, such that the indirect effect of perceived stigma on subjective well-being through sexual self-identification was the highest among Chinese gay and bisexual men with low self-stigma. Given that research into the mental health and well-being of Chinese gay and bisexual men is still in its infancy, our findings are important and may help in developing and improving socially and psychologically sensitive counseling services or intervention strategies for these populations.

A Randomized Controlled Trial of Two Parenting Interventions on Enhancing Parental Resilience Resources and Reducing Children's Problem Behaviors in Chinese Cross-Boundary Families: Positive Benefits and Moderation Effects.

Daily cross-boundary schooling between Shenzhen and Hong Kong constitutes a constant challenge for Chinese cross-boundary families in terms of parenting burden. To address their most urgent parenting needs, we adapted and evaluated two intervention approaches-improving emotional regulation and providing knowledge about Hong Kong. A cluster randomized controlled trial with repeated assessments (pre-, post-intervention, and one-month follow-up) was adopted to evaluate the intervention effects on the increases of parental resilience resources and reduction of children's problem behaviors. We further conducted moderation analyses to investigate whether parents with more increases in parental resilience resources would report a greater reduction in children's problem behaviors. A total of 214 mothers of cross-boundary families were randomly assigned to the emotional regulation arm (ER, n = 120) or the information provision arm (IP, n = 94). Both intervention arms showed positive effects on emotional regulation strategies, and the IP arm outperformed the ER arm in knowledge acquisition. Both arms showed significant and comparable improvements in parental self-efficacy and children's problem behaviors. Moreover, participants in the IP arm who reported more improvements in parental resilience resources showed a greater reduction in children's problem behaviors. By adapting two interventions to a new population of cross-boundary families, this trial extended the benefits from parents to children and demonstrated that the improvement of parental resilience resources makes a difference in reducing children's problem behaviors in the IP arm. Future studies are suggested to focus on parental resilience resources and maximize the benefits on children's outcomes.

Trajectories of complex posttraumatic stress symptoms among Chinese college students with childhood adversities: The role of self-compassion.

BACKGROUND: Complex posttraumatic stress disorder (CPTSD) is associated with severe impairments in psychosocial functions, but related longitudinal research is limited. To promote the mental health of college students with childhood adversities, it is imperative to investigate the development of CPTSD symptoms and the predictive factors. OBJECTIVES: The study aimed to examine the latent trajectories of CPTSD symptoms among college students with childhood adversities and to identify the role of self-compassion in differentiating potential trajectories. METHODS: A total of 294 college students with childhood adversities completed self-report questionnaires on demographic backgrounds, childhood adversities, CPTSD symptoms, and self-compassion three times with an interval of three months. Latent class growth analysis was used to determine the trajectories of CPTSD symptoms. Multinomial logistic regression was performed to examine the association between self-compassion and trajectories subgroups while adjusting for demographic variables. RESULTS: Three heterogeneous groups of CPTSD symptoms among college students with childhood adversities were identified: the low-symptoms group (n = 123, 41.8 %), the moderate-symptoms group (n = 108, 36.7 %), and the high-risk group (n = 63, 21.4 %). Multinomial logistic regression showed that, after adjusting for demographic variables, students with higher levels of self-compassion were less likely to belong to the moderate-symptoms and high-risk group in comparison to the low-symptoms group. CONCLUSIONS: The results suggest the trajectories of CPTSD symptoms of college students with childhood adversities were heterogeneous. Self-compassion was a protective factor against the development of CPTSD symptoms. The present study provided insights into the mental health promotion for individuals with adversities.

Chemical synthesis of carbon dots with blue, green and red emission for dopamine reversible switching probes.

Carbon dots (CDs) possess the merits such as energy efficiency, green sustainability and environmental friendliness, comparing with top-down synthesis methods at higher pressure or temperature condition. Here, a variety of emission states CDs were prepared by using the method of room temperature chemistry by selecting green raw materials such as glucose, p-phthalaldehyde and m-diethylaminophenol. The luminescence mechanism was studied in detail. The luminescent center of blue emitting carbon dots (B-CDs) and green emitting carbon dots (G-CDs) is CO bond, and the increased contents of CO bond lead to the creation of new energy levels between the energy gaps of HOMO and LUMO levels, which results in the red shift of luminescence wavelength. The emission state of red emitting carbon dots (R-CDs) is due to the formation of amino N. In addition, R-CDs have an exclusive respond to dopamine (DA) and are regarded as good fluorescent probes for detecting DA. Furthermore, the addition of ascorbic acid (AA) restores the luminescence of R-CDs quenched by DA. Therefore, R-CDs has great application potential as a selective fluorescent "turn on-off" probe.

Delayed infected hematoma in retrosternal area following total thyroidectomy: a case report.

Introduction and Importance: Postoperative neck hematoma (PNH), a rare complication following thyroidectomy, occurs in only 1.1-3.15% of cases and can lead to life-threatening outcomes. More rarely, delayed PNHs with atypical clinical manifestations and positions have not yet been reported. Early identification and immediate medical intervention are of utmost importance in such cases. Case Presentation: The authors represented a patient with thyroid cancer adherent to the trachea, who underwent post-thyroidectomy, experienced delayed PNH in the retrosternal region and was infected by respiratory pathogens. Meanwhile, the patient developed recurrent laryngeal nerve (RLN) paralysis after surgery. PNH was not identified in the clinical manifestations; instead, it was detected only through successive cervical ultrasound examinations. Clinical Discussion: Although rare, PNH can lead to serious complications, especially delayed complications or those in atypical positions, without neck swelling. When simultaneously with RLN paralysis, the hematoma may be neglected. Therefore, early diagnosis and treatment are crucial. Conclusion: Clinicians should be vigilant of atypical PNH because neck swelling may be absent. Cervical ultrasonography is essential for diagnosis and can be performed multiple times. Cervical CT scans should be part of the routine procedure, while contrast-enhanced ultrasound can help detect active bleeding. Early postoperative antibiotics are recommended if the tumor is closely attached to the trachea.

What triggers depressive symptoms among gay and bisexual men? A sequential mediation model of sexual minority-related stigma and self-criticism.

A growing number of studies has shown that gay and bisexual men are more likely to experience adverse mental health status than their heterosexual counterparts. Stigma-related stress and self-criticism are believed likely to exacerbate depressive symptoms among gay and bisexual men. This research used cross-sectional findings to illustrate the mediating role of internalized self-stigma and self-criticism in the association between perceived public stigma and depressive symptoms. A total of 317 Chinese gay and bisexual men (267 gays and 50 bisexuals with a mean age of 25.29) were invited to participate in this study from October to November 2021. Sociodemographic characteristics, perceived public stigma, internalized self-stigma, self-criticism and depressive symptoms were measured through self-reported online questionnaires. The results indicated that the association between perceived public stigma and depressive symptoms was sequentially mediated by internalized self-stigma and self-criticism. The findings indicated that public stigma, as a distal stressor, was perceived and internalized as self-stigma by gay and bisexual men. This self-stigma may pose a risk for depressive symptoms via self-criticism (a maladaptive consequence of their attempts to reduce cognitive dissonance). These results highlight the necessity of reducing sexual minority-related stigma and self-criticism to reduce depressive symptoms. Our findings appeal to society to further decrease prejudice and stigma, increase tolerance, and focus on the negative mental health status of gay and bisexual men.

(In)congruence in child-mother relationships and depressive symptoms in cross-boundary families.

A large number of school-aged children traveling between Mainland China and Hong Kong every day to attend school are known as cross-boundary students (). Daily cross-boundary schooling is likely to be a constant challenge for cross-boundary students and their families, putting them at great risk of mental health problems (e.g., depression). Nevertheless, intergenerational relationships may be positive contributors to their adaptation. Guided by the interdependence theory and the operations triad model, this study employed dyadic response surface analysis to take into account linear and curvilinear associations between child-mother relationships and their depressive symptoms. The cross-sectional results based on 187 child-mother dyads showed that when children and mothers reported relatively high levels of closeness and relatively low levels of conflict, they reported fewer depressive symptoms. The extreme closeness between children and their mothers posed particular risks to mothers, increasing maternal depressive symptoms. When children and mothers reported varying levels of closeness and conflict, they displayed greater depressive symptoms. One exception was that no significant association was observed between incongruence in closeness and children's depressive symptoms. Family-based interventions should be considered for promoting optimal child-mother combinations. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Warm and Harsh Parenting, Self-Kindness and Self-Judgment, and Well-Being: An Examination of Developmental Differences in a Large Sample of Adolescents.

Objectives: This study aimed to examine the associations between warm and harsh parenting and adolescent well-being, and the mediating effects of self-kindness and self-judgment, in relationships. Moreover, this study investigated developmental differences across three adolescence stages (early, middle, and late). Methods: In total, 14,776 Chinese adolescents (mean age = 13.53 ± 2.08, 52.3% males), including individuals in early (10-12 years old, N = 5055), middle (13-15 years old, N = 6714), and late adolescence (16-18 years old, N = 3007) participated in this study. All the adolescents rated their levels of warm and harsh parenting, self-kindness and self-judgment, and well-being. Structural equation modeling (SEM) was adopted to examine the mediation model. Multi-group analysis was conducted to investigate differences in the mediation model across the different developmental stages. Results: Both warm and harsh parenting were related to adolescent well-being through the mediating effects of self-kindness and self-judgment. However, warm parenting exerted a more substantial impact on adolescent well-being. Self-kindness had a more robust mediating effect than self-judgment in relationships. Moreover, harsh parenting had a weaker impact on adolescent well-being in late adolescence than in early and middle adolescence. Warm parenting had a more significant impact on adolescent well-being in early adolescence than in middle and late adolescence. Conclusions: Overall, warm parenting had a more substantial effect than harsh parenting on adolescent well-being. The findings also highlighted the crucial mediating effect of self-kindness in the relationships between parenting and well-being. Moreover, this study also indicated the importance of warm parenting in early adolescence. Intervention programs should focus on enhancing the level of warm parenting to promote self-kindness in adolescents, in order to improve their well-being.
