ItemNo Preview AvailableExtroversion Fosters Career Competence among Adolescents in Hong Kong(Springer Science and Business Media LLC, 2022-06)Adolescents often feel helpless about planning their career in highly competitive societies such as Hong Kong. Relatively limited research has been conducted to examine whether being extrovert can influence adolescents’ career-related knowledge and career decision self-efficacy (CDSE). Methods: This cross-sectional study explored the relationship between extroversion, career knowledge and CDSE among 535 Hong Kong high school students based on Social Cognitive Career Theory and Trait and Factor Theory. Descriptive data analysis, correlation tests and structural equation modelling were used. Results: Study respondents displayed a low level of career knowledge and CDSE. Extroversion had a directly positive effect on CDSE (β = 0.219, p < 0.001), while career knowledge significantly mediated the relationship between extroversion and CDSE (β = 0.185, p < 0.001). Conclusions: This study provided a model to understand high school adolescents’ career decision self-efficacy, and empirically supported career training interventions to enhance adolescents’ self-efficacy and confidence in being more outgoing.

However, little relevant research has been conducted in the Chinese context. This mixed-method study aimed to understand how women with PCOS in China perceive their bodies and to examine the association between body image and depression. METHODS: First, 101 PCOS patients participated in a survey using the Body Surveillance subscale of the Objectified Body Consciousness Scale, the Short-form Mishel Uncertainty in Illness Scale, the Appearance Anxiety Scale, and the Beck Depression Inventory-II, which measured participants' self-objectification, illness ambiguity, appearance anxiety, and depression, respectively. Second, fifteen women joined face-to-face semi-structured in-depth interviews, investigating their illness ambiguity, objectified experience, and behaviors to pursue beauty. RESULTS: Results indicated a high level of self-objectification, illness ambiguity, appearance anxiety, and depression among women with PCOS in China and supported the significant associations among the outcomes. Qualitative findings presented a body image of the precarious body, indiscernible identity, and distraught mind. LIMITATIONS: A convenient sampling method was used. The generalization of the study results needs further validation. Future longitudinal studies are necessary to clarify the causal relationships among outcomes. CONCLUSIONS: This study presented women's body image with PCOS and found the negative impact of body image on their depression levels. This study was of both theoretical and practical significance. Appropriate mind-body therapies were suggested for them.

Methods: Ninety-one families were randomly allocated to either the six-session intervention group (n = 48) or the wait-list control group (n = 43) and completed the randomized trial. For both groups, a range of psychosocial outcome measures were taken before the intervention (T0), postintervention (T1), and 6 weeks after the intervention (T2). Results: Relative to the control group, the intervention group was significantly improved over time in their levels of perceived stress, depression, and a number of holistic well-being measures, including nonattachment, afflictive ideation, and general vitality. Discussion: The results provided empirical support for an IBMS-informed psychosocial intervention in reducing stress and depression and enhancing well-being among parents of children with eczema.

METHODS: 157 Chinese informal caregivers of lung cancer patients were recruited together with the family members for whom they were providing care, and randomly assigned to either integrative body-mind-spirit intervention (I-BMS) or cognitive behavioral therapy (CBT). Patient-caregiver dyads attended the same arm of intervention in separate groups for 8 weeks. Assessments of generic QoL, anxiety, depression, perceived stress, insomnia, and caregiving burden were measured before intervention (T0), within 1-week (T1), 8-week (T2), and 16-week (T3) post-intervention. RESULTS: Adopting the intention-to-treat analysis, family caregivers in receipt of both I-BMS and CBT exhibited a statistically significant improvement in generic QoL immediately following intervention and at follow-up assessments, with moderate effect size. Improvement of insomnia was found at T1 for both modes, which deteriorated at follow-up; both modes reduced anxiety and perceived stress at follow-up. No intervention effect was observed in depression and domains of caregiving burden. There was no significant interaction effect between intervention type and time. No main or interaction effect between sample background variables and intervention type was found to predict symptomatic changes at T1 and T3. CONCLUSIONS: Culturally attuned I-BMS and CBT exhibited equivalent effectiveness in improving psychological distress and generic QoL for family caregivers of lung cancer patients. To improve the evaluation of outcomes, future study could benefit from incorporating a usual care control.

Assessments were conducted at baseline, within one, eight- and sixteen-weeks post-intervention. Effects of treatment group across time were analyzed by multilevel modeling.Findings: CBT led to greater reduction in emotional vulnerability than I-BMS. I-BMS resulted in greater increase in overall QoL and spiritual self-care, and more reduction in depression than CBT. Patients in both interventions experienced improvement in physical, emotional and spiritual, except social, domains of QoL.Conclusion: I-BMS was more efficacious for diverse domains of QoL, and CBT was more effective for emotional well-being, despite the relatively small between-group effect sizes.Implications for psychosocial providers/policy: (1) With the expanding repertoire of psychosocial interventions for families facing lung cancer, it has become imperative to investigate the comparative efficacies of empirically supported and culturally adapted interventions. (2) Our findings show that I-BMS was more effective for diverse domains of QoL, while CBT was more efficacious with emotional well-being, although both interventions led to significant improvements in physical, emotional and spiritual domains of patient QoL. (3) Patient-caregiver parallel groups have been shown to be effective for enhancing QoL of Chinese lung cancer patients. (4) Care professionals are encouraged to dispense interventions based on the idiosyncratic needs and preferences of the patients to maximize the treatment effects.

ItemNo Preview AvailableThe mental health of women with polycystic ovary syndrome: a systematic review and meta-analysis.(Springer, 2021-02)Polycystic ovary syndrome (PCOS) has been proposed to be associated with several mental health problems, including anxiety, depression, diminished sexual satisfaction, and lowered health-related quality of life, etc. A systematic review and meta-analysis of published literature was conducted comparing the mental health of women with and without PCOS. Ten English and Chinese databases were searched up to 12/31/2018. Random-effects models were introduced, and subgroup analysis, sensitivity test, and meta-regression were carried out to determine the source for heterogeneity among studies. Forty-six studies, including 30,989 participants (9265 women with PCOS and 25,638 controls), were qualified for review according to the inclusion criteria. Twenty-eight studies reported depression symptoms, 22 studies were on anxiety, 16 studies showed quality of life (QoL) status, 12 studies were about sexual dysfunction, five on emotional distress, four on binge eating, and four on somatization. Women with PCOS reported significantly higher depression (SMD = 0.64; 95% CI 0.50-0.78), anxiety (SMD = 0.63; 95% CI 0.50-0.77), lower QoL (SMD = - 0.55; 95% CI -0.69 to -0.40), and not significant sexual dysfunction (SMD = - 0.24; 95% CI - 0.49 to 0.01). Studies from different countries, adopting various diagnosis criteria, using diverse instruments, as well as in different years, have reported heterogenetic results. Women with PCOS in China reported a larger effect size of depression and anxiety than patients from other countries. The results of this study have indicated that women with PCOS suffer from depression, anxiety, and experience a lower quality of life, whereas their sexual function is not distinct from that of healthy women. Psychological health care interventions for women with PCOS were addressed.

ItemThe Counterintuitive Relationship between Telomerase Activity and Childhood Emotional Abuse: Culture and Complexity(MDPI AG, 2021-02-08)BACKGROUND: A burgeoning literature has found relationships between telomere length, telomerase activity, and human health and longevity. Although some research links a history of childhood adversity with shortened telomere length, our review found no prior research on the relationship between child maltreatment history and telomerase activity in adulthood. We hypothesized a negative relationship between child maltreatment and telomerase activity and hypothesized that the association would be moderated by sex. METHODS: These relationships were tested on a sample of 262 Hong Kong Chinese adults (200 females versus 62 males) with mild to moderate depression. RESULTS: Counterintuitively, emotional abuse was positively associated with telomerase activity, while other maltreatment types were non-significant. The positive relationship between emotional abuse and telomerase activity was significantly moderated by the sex of the participant. CONCLUSIONS: We advance two possible explanations for this finding (1) a culturally informed resilience explanation and (2) a homeostatic complexity explanation. The two explanations are not mutually exclusive. This trial is registered under Hong Kong Clinical Trial Register number HKCTR-1929. SIGNIFICANCE STATEMENT: Emotional abuse was significantly positively associated with telomerase activity. There are at least two non-mutually exclusive explanations for the findings. Simply put, either (1) in the cultural context of Hong Kong emotional abuse was not a risk factor, and/or (2) the conceptualization of telomerase activity as a straightforward indicator of longevity is overly simplistic. The first story we might term a "resilience explanation" while the second we might call a "homeostatic complexity" story.

ItemSpectroscopic study of L-DOPA and dopamine binding on novel gold nanoparticles towards more efficient drug-delivery system for Parkinson's disease(PERGAMON-ELSEVIER SCIENCE LTD, 2022-03-05)Nano-drug delivery systems may potentially overcome current challenges in the treatment of Parkinson's disease (PD) by enabling targeted delivery and more efficient blood-brain penetration ability. This study investigates novel gold nanoparticles (AuNPs) to be used as delivery systems for L-DOPA and dopamine by considering their binding capabilities in the presence and absence of a model protein, bovine serum albumin (BSA). Four different AuNPs were prepared by surface functionalization with polyethylene glycol (PEG), 1-adamantylamine (Ad), 1-adamantylglycine (AdGly), and peptidoglycan monomer (PGM). Fluorescence and UV-Vis measurements demonstrated the strongest binding affinity and L-DOPA/dopamine loading efficiency for PGM-functionalized AuNPs with negligible impact of the serum protein presence. Thermodynamic analysis revealed a spontaneous binding process between L-DOPA or dopamine and AuNPs that predominantly occurred through van der Waals interactions/hydrogen bonds or electrostatic interactions. These results represent PGM-functionalized AuNPs as the most efficient at L-DOPA and dopamine binding with a potential to become a drug-delivery system for neurodegenerative diseases. Detailed investigation of L-DOPA/dopamine interactions with different AuNPs was described here for the first time. Moreover, this study highlights a cost- and time-effective methodology for evaluating drug binding to nanomaterials.

The optimization of the synthesis of CDs is investigated towards achieving shorter reaction time, better product yield and fluorescence quantum efficiency. Precursors such as citric acid and thiourea were chosen for the synthesis of CDs. Among the various synthetic methodologies, it is found that the pyrolysis method offers ∼50% product yield within 15 min. The morphology and optical properties of the prepared CDs are characterized using the typical microscopic and spectroscopic techniques, respectively. The synthesized CDs exhibit quasi-spherical shape with an average particle size of 1.7 nm. The excitation dependent emissive properties of CDs are investigated by time resolved fluorescence spectroscopy. Furthermore, the excellent fluorescence properties (ϕ = 11%) of CDs are explored as a fluorescent fingerprint powder for the identification of latent fingerprints on various substrates. In addition, the presence of picric acid in latent fingerprints was detected. Furthermore, this study is extended to perform real time detection of fingerprints and harmful contaminants in fingerprints by utilizing a smartphone-based RGB color analysis tool. Based on these investigations, the prepared CDs could be a prospective fluorescent material in the field of forensics.

ItemSurface Lattice Resonances in Self-Assembled Gold Nanoparticle Arrays: Impact of Lattice Period, Structural Disorder, and Refractive Index on Resonance Quality(American Chemical Society, 2020-11-17)Surface lattice resonances are optical resonances composed of hybridized plasmonic and diffractive modes. These collective resonances occur in periodic arrays of plasmonic nanoparticles with wavelength-scale interparticle distances. The appearance and strength of surface lattice resonances strongly depend on the single particle localized surface plasmon resonance and its spectral overlap with the diffractive modes of the array. Coupling to in-plane orders of diffraction is also strongly affected by the refractive index environment and its symmetry. In this work, we address the impact of the interparticle distance, the symmetry of the refractive index environment, and structural imperfections in self-assembled colloidal monolayers on the plasmonic–diffractive coupling. For this purpose, we prepared hexagonally ordered, nonclose packed monolayers of gold nanoparticles using a fast and efficient, interface-mediated, colloidal self-assembly approach. By tuning the thickness and deformability of the polymer shells, we were able to prepare monolayers with a broad range of interparticle distances. The optical properties of the samples were studied experimentally by UV–Vis spectroscopy and theoretically by finite difference time domain simulations. The measured and simulated spectra allow a comprehensive analysis of the details of electromagnetic coupling in periodic plasmonic arrays. In particular, we identify relevant criteria required for surface lattice resonances in the visible wavelength range with optimized quality factors in self-assembled monolayers.
