Addressing adolescent social and emotional concerns: Insights from loneliness, burnout, and preferred conversation topics in Asian and UK contexts post-pandemic.

This study investigated relationships between social and emotional concerns, loneliness, and school burnout, as these factors are associated with adaptive functioning during adolescence residence in Asia (i.e., China, Hong Kong) and the UK. Analysis of data from 2849 participants illuminated compelling insights. The participants reported a high level of loneliness, notably among girls in the UK. The research generated 11 preferred conversation topics (i.e., future and aspirations, anything, learning, nothing, mental health, personal interests, health, relationships, psychosocial issues, social issues, feelings). Among them, future and aspirations lead the way, aligning with developmental needs. A desire for mental health discussions coexisted with heightened loneliness and burnout among participants who pursued such conversations. The low achievers tended to talk about mental health issues or have nothing to say. High achievers were drawn to social issues, emphasizing their distinct socio-emotional needs. Forging a connection between personal interests and mitigated school burnout underscores the potential for individual passions to harmonize with educational experience. These findings underscore the exigency for bespoke interventions addressing the evolving emotional terrain of adolescents, especially in the pandemic's aftermath. The study's implications underscore the importance of empathetic listening and proactive engagement between adolescents and supportive adults. This research enriches the comprehension of pandemic-induced adolescent experiences and suggests avenues for future investigations into long-term emotional well-being. CLASSIFICATION CODE: 2800 (Developmental Psychology).

Measurement invariance of the Multidimensional Depression Assessment Scale (MDAS) across gender and ethnic groups of Asian, Caucasian, Black, and Hispanic.

BACKGROUND: Major Depressive Disorder is a severe and highly disabling mental illness. Almost all self-reported questionnaires have overlooked the interpersonal symptoms of depression which are important across gender and culture. The Multidimensional Depression Assessment Scale (MDAS) developed by Cheung and Power (2012) entails comprehensive emotional, cognitive, somatic, and interpersonal subscales. It addresses the criticism that existing self-report depression scales might not cover sufficient phenomenological heterogeneity of depression. The current study aimed to evaluate the psychometric properties of the MDAS across gender and four major ethnic groups of Caucasian, Black, Asian and Hispanic, including reliability and concurrent validity against the Centre for Epidemiological Studies Depression Scale (CESD) and Patients Health Questionnaire (PHQ-9). It also aimed to establish a stable factor structure across gender and ethnic groups and test the measurement invariance to enhance its potential for clinical use. METHODS: A community sample of 3499 participants from four ethnic groups were recruited via online crowdsourcing sites of Qualtrics and Amazon M Turk. Each individual completed a demographic questionnaire, the MDAS, CESD and PHQ-9. RESULTS: There was good internal consistency (Cronbach's alpha >0.90) and concurrent reliability across gender and ethnic groups. Strict measurement invariance was established for MDAS over a four-factor factor structure corresponding to the four subscales. CONCLUSIONS: The MDAS showed good psychometric properties and measurement invariance of a four-factor structure, suggesting its potential to be used in clinical settings across gender and ethnic groups. LIMITATIONS: Participants all answered the questionnaires in English, which could hinder cultural variations in their expression of symptoms.

Validation of the 5-D Itch Scale in Three Ethnic Groups and Exploring Optimal Cutoff Values Using the Itch Numerical Rating Scale.

BACKGROUND: Chronic pruritus is a common and distressing condition that has serious emotional and psychosocial consequences. Due to its subjective nature, self-report questionnaires are widely implemented as cost-effective measures to gauge the severity of chronic pruritus. The current study is aimed at validating the 5-D itch scale in three ethnic groups-Black, Asian, and Hispanic-with the well-validated Itch Numerical Rating Scale (NRS) and Worst Itch NRS (WI-NRS) and developing its cutoff value using receiver operating characteristics (ROC) and inspection of the area under the curve (AUC) across ethnic groups. At the same time, it is aimed at comparing the concurrent prevalence of itch and depression in these populations, who often form ethnic minorities in many countries. The current study addresses the knowledge gap of cultural adaptation of the 5-D pruritus scale for greater usage. METHODS: Community samples of three ethnic groups were recruited from an online platform of Qualtrics and administered the self-report questionnaires of Itch-NRS, 5-D itch scale, and Patient Health Questionnaire-9 (PHQ-9) to measure their pruritus domains, itch intensity, depression screening, and its severity. Informed consent was obtained from all participants. Subgroup analysis was conducted, including concurrent validity and cutoff values compared between each ethnic group. Concurrent prevalence of itch and depression was evaluated using the cutoff value of Itch-NRS and PHQ-9. RESULT: A total of 2323 participants were included in the study. A significant positive correlation (p < 0.001) was found between the Itch-NRS, WI-NRS, and 5-D itch scale. The cutoff value of the 5-D itch scale was established for the three ethnic groups using ROC, with a cutoff value of Itch-NRS as a reference. CONCLUSIONS: The 5-D itch scale has demonstrated sound psychometric properties in three ethnic groups and is closely related to Itch-NRS. The analysis of the cutoff value of the 5-D itch scale suggests that different cutoff values should be considered to reduce the inflation of pruritus severity.

Survey on common reference intervals for general chemistry analytes in Hong Kong.

INTRODUCTION: Reference intervals (RIs) are essential tool for proper interpretation of results. There is a global trend towards implementing common RIs to avoid confusion and enhance patient management across different laboratories. However, local practices with respect to RIs lack harmonisation. METHODS: We have conducted the first local survey regarding RIs for 14 general chemistry analytes in 10 chemical pathology laboratories that employ four different analytical platforms (Abbott Architect, Beckman Coulter AU, Roche Cobas, and Siemens Dimension EXL). Analytical bias was assessed by an inter-laboratory results comparison of external quality assurance programmes. RESULTS: Sufficient inter-laboratory and inter-platform agreement regarding the 10 analytes (albumin, alanine aminotransferase, aspartate aminotransferase, chloride, gamma-glutamyl transferase, phosphate, potassium, sodium, total protein, and urea) were demonstrated. However, the RIs were heterogeneous across all laboratories, with percentage differences of the upper RI value of up to 47% for aspartate aminotransferase (absolute difference of 16 U/L), 29% for urea (1.8 mmol/L), and 18% for potassium (0.8 mmol/L). The percentage difference between lower RI values was up to 24% for urea (0.6 mmol/L), 22% for phosphate (0.16 mmol/L), and 8% for total protein (5 g/L). The coefficients of variation of the upper RI values of potassium and sodium were 1.2 times and 1.0 times of their corresponding between-subject biological variation, respectively, representing unnecessary variations that are overlooked and unchecked in current practice. CONCLUSIONS: We recommend the use of common RIs for general chemistry analytes in Hong Kong to prevent interpreter confusion, improve electronic data transfer, and unite laboratory practice. This is the first local study on this topic, and our data can lay the groundwork for increasing harmonisation of RIs across more laboratory tests.

Prevalence of abnormal Papanicolaou smears in female sex workers in Hong Kong.

OBJECTIVE. To investigate the prevalence of pre-cancerous uterine cervix lesions as detected in Papanicolaou (Pap) smears from female sex workers in Hong Kong. DESIGN. Retrospective analysis of laboratory records. SETTING. Private anatomical pathology laboratory, Hong Kong. PATIENTS. Female sex workers undergoing Pap smear examinations at two non-governmental organisations between 2006 and 2012. MAIN OUTCOME MEASURES. Detection of pre-cancerous uterine cervical conditions and their management. RESULTS. A total of 2697 satisfactory Pap smears from female sex workers were performed during the study period from 2006 to 2012. In these subjects, the point prevalence of low-grade squamous intraepithelial lesion and atypical squamous cells of unknown significance was 10.12% (compared with 3.92% for the general population during the same period), whereas that of high-grade squamous intraepithelial lesions and atypical squamous cells of unknown significance with or without high-grade intraepithelial lesions was 2.22% (compared with 0.54% in the general population). For both categories of lesions, the higher prevalence among female sex workers than in the general population was statistically significant. Most patients who had abnormal Pap smears received proper referrals and follow-up management according to recommended guidelines. CONCLUSIONS. Female sex workers in Hong Kong as a group had a significantly higher prevalence of abnormal Pap smears than the general population. Non-governmental organisations providing free-of-charge screening services to these women helped early detection and proper follow-up for those who had abnormal Pap smears, whilst also increasing their awareness of women's health issues.

Microbial-growth inhibition during composting of food waste: effects of organic acids.

Factorial designs were employed to analyze the inhibitory effects of acetic, butyric, lactic, and propionic acids on composting microorganisms. Compost samples were withdrawn on different days of composting and treated with acids alone and in combination (at 0 and 0.5 mmol/g). Microorganisms were enumerated to determine degree of growth inhibition. Generally, inhibition was more severe on the day when pH decreased rather than on the day when pH started to increase. Butyric or lactic acid alone, and the combination of butyric, lactic, and propionic acids, significantly inhibited thermophilic bacteria. Only 51.0-65.0% of the thermophilic bacteria exist if 0.5 mmol/g of these acids were present in compost. Temperature, microbial populations, and microbial growth phase might cause variation in the inhibitory effects of acids. These findings are useful not only in the study of microorganisms in acidic microenvironments, but also in preventing microbial-growth inhibition by predicting population via a regression model.
