The mediating effect of dispositional mindfulness on the association between UPPS-P impulsivity traits and gaming disorder among Asia-Pacific young adults.

BACKGROUND: Little evidence is available to verify the mediating effect of dispositional mindfulness on the association between gaming disorder and various impulsivity traits. The present study aimed to investigate the mediating effect of dispositional mindfulness on the association between the five UPPS-P impulsivity traits and the risk of gaming disorder among young adults. METHODS: It was an inter-regional cross-sectional study using online survey in Australia, Japan, The Philippines and China. Impulsivity measured by the UPPS-P Impulsive Behavior Scale-Short version; dispositional mindfulness measured by the Mindfulness Attention Awareness Scale; and the risk of gaming disorder measured by the Internet Gaming Disorder Scale were collected in the focal regions. Structural equation modeling was performed by SPSS AMOS version 26 to verify the study hypotheses. Bootstrapped 95% confidence interval was reported. Statistical significance was indicated by the p-value below 0.05. RESULTS: Among the 1,134 returned questionnaires, about 40% of them aged 18-20 years and 21-23 years, respectively. 53.8% were male. 40.7% had been playing digital and video games for over 10 years. The prevalence of gaming disorder was 4.32%. The model fitness indices reflected that the constructed model had an acceptable model fit (χ2(118) = 558.994, p < 0.001; χ2/df = 4.737; CFI = 0.924; TLI = 0.890; GFI = 0.948; RMSEA = 0.058; SRMR = 0.0487). Dispositional mindfulness fully mediated the effect of positive urgency and negative urgency on the risk of gaming disorder. The effect of lack of premeditation on the risk of gaming disorder was partially mediated by dispositional mindfulness. However, dispositional mindfulness did not mediate the effect of sensation seeking on the risk of gaming disorder. CONCLUSIONS: The varied associations between dispositional mindfulness and the five impulsivity traits hints that improving some impulsive traits may increase dispositional mindfulness and so lower the risk of gaming disorder. Despite further studies are needed to verify the present findings, it sheds light on the need to apply interventions on gamers based on their impulsivity profile. Interventions targeting at emotion regulation and self-control such as mindfulness-based interventions seem to be effective to help gamers with dominant features of urgency and lack of premeditation only. Other interventions shall be considered for gamers with high sensation seeking tendency to enhance the effectiveness of gaming disorder prevention.

Evaluation of N95 respirators on fit rate, real-time leakage, and usability among Chinese healthcare workers: study protocol of a randomized crossover trial.

Background: N95 respirators are used to limit the transmission of respiratory viruses in clinical settings. There are two to three major types of N95 available for all healthcare workers in Hong Kong. However, after the coronavirus outbreak and the consequent shortage of many commonly used respirators, several new N95 respirators were adopted temporarily in clinical settings without evaluation. Prior literature indicates that traditional N95 respirators used in hospitals in Hong Kong are not fit for Chinese people and have fit rates ranging from 50 to 60%. This study aims to investigate and compare the fit rate, real-time leakage, and mask usability of traditional and new N95 respirators among Chinese healthcare workers. Methods: This study will employ two sequential phases. Phase 1 has a cross-sectional exploratory design used to investigate the fit rate and mask usability of three types of respirators. Phase 2 will examine the effectiveness of respiratory protection by comparing traditional and new N95 respirators by a randomized crossover trial. Eligible participants will be randomly allocated through a controlled crossover experiment to either a traditional or new respirator group (n = 100 in each arm) for performing standard clinical procedures. The primary outcome (real-time leakage) will be recorded at 30 s intervals during nasopharyngeal suctioning and cardiopulmonary resuscitation. The secondary outcomes are the fit rate and mask usability. After a 2 min suctioning (15 s twice) and 4 min one-person CPR, the fit rate (assessed by standard N95 fit testing) and mask usability (measured by self-reported mask usability scale) will be recorded as data of post-procedure. After 10 min rest, measurement of real-time leakage (i.e., crossover), fit test, and usability will be repeated. Discussion: The result of real-time leakage will be a vital indicator of the respiratory protection of Chinese healthcare workers while performing prevalent clinical procedures, such as resuscitation. The fit rate and usability result will serve as an essential reference for consumable purchase policy in clinical settings.Trial registration: ISRCTN registry: ISRCTN40115047.

The effects of an e-health brisk walking intervention in increasing moderate-to-vigorous physical activity in physically inactive older people with cognitive frailty: study protocol for a randomized controlled trial.

BACKGROUND: Cognitive frailty is a risk for many adverse health outcomes that are commonly observed in older people. Physical activity is known to be effective to reserve cognitive frailty but the prevalence of physical inactivity is still high in older people. E-health enhances behavioural change effects through an innovative way to deliver behavioural change methods that can enhance the behavioural change effects. However, its effects on older people with cognitive frailty, its effects compared with conventional behavioural change methods, and the sustainability of the effects are unclear. METHODS: This study employs a single-blinded, two-parallel-group, non-inferiority, randomized controlled trial design with a 1:1 group allocation ratio. Eligible participants are aged 60 years or above, have cognitive frailty and physical inactivity, and possess a smartphone for more than six months. The study will be conducted in community settings. In the intervention group, participants will receive a 2-week brisk-walking training followed by a 12-week e-health intervention. In the control group, participants will receive a 2-week brisk-walking training followed by a 12-week conventional behavioural change intervention. The primary outcome is minutes of moderate-to-vigorous physical activity (MVPA). This study aims to recruit a total of 184 participants. Generalized estimating equations (GEE) will be used to examine the effects of the intervention.

Prediction of problem gambling by demographics, gaming behavior and psychological correlates among gacha gamers: A cross-sectional online survey in Chinese young adults.

Objective: The objective of this study is to explore the association of problem gambling with demographics, psychological distress, and gaming behavior in young adult gacha gamers in Hong Kong. Materials and methods: Cross-sectional data was collected in the first and fifth waves of COVID-19 pandemic in Hong Kong online. Participants who aged 18-25 years and had been playing gacha games over the past 12 months were recruited. Stepwise multiple regression was used to explore the association among risk of problem gambling, gaming behavior, participation in gaming activities and psychological distress. A two-sided p-value <0.05 was considered as statistical significance. Results: Three hundred and thirty-seven completed questionnaires were received with no missing data. 34.7% (n = 117) of the participants had non/low-risk of problem gambling. About 40% (n = 136) of them had moderate-risk and the remaining 25% (n = 84) were at high risk of problem gambling. A higher proportion of female participants (78.6%) were found in high-risk group as compared to 39.7% and 55.6% only in the non/low-risk and moderate-risk groups, respectively. The regression model (R 2 = 0.513, F = 71.895, p < 0.001) showed that 51.3% of the variance of the total problem gambling score could be explained by stress, anxiety, monthly expenses on gacha purchases, number of motives for gacha purchase and number of gambling activities engaged. Conclusion: The present study provides empirical evidence to support the association between problem gambling and microtransaction especially for gacha which is the most popular type of video game microtransaction in Asia. The established regression model suggests that gacha gamers with higher risk of problem gambling tend to have greater stress, higher anxiety level, spend more on gacha purchase, have more motives for gacha purchases and engage in more gambling activities. In contrast to the extant literature, higher proportion of female participants in high-risk group indicates that female gacha gamers are also at very high risk of becoming problem gamblers.

Study protocol for a randomized controlled trial comparing the effectiveness of physical exercise and melatonin supplement on treating sleep disturbance in children with autism spectrum disorders.

BACKGROUND: Previous study showed that both melatonin supplement and physical exercise intervention could improve sleep quality in children with autism spectrum disorders (ASD) with the increase in endogenous melatonin level. However, none of the studies have directly compared the effectiveness between the two interventions on treating sleep disturbance in children with ASD. Without direct comparison, we do not know which intervention is better. Thus, we designed a study to compare which intervention is more effective to treat sleep disturbance in children with ASD and to examine whether the combination of the two could be the most efficacious. We present a protocol for conducting a randomized controlled trial to compare the effectiveness of physical exercise and melatonin supplement on treating sleep disturbance in children with ASD. STUDY DESIGN: The proposed study will be a four-group randomised control trial (RCT) design, with equal allocation of participants to the three intervention groups and one control group. METHODS: All eligible participants will be randomly allocated to a morning jogging group, a melatonin supplement group, a combination group and a control group. Changes in sleep quality will be monitored through actigraphic assessment and parental sleep logs. Melatonin levels represented by 6-sulfoxymelatonin will be measured from the participants' 24-h and the first morning void urinary samples. All the assessments will be carried out before the intervention (T1), in the mid of the study (5 weeks after the commencement of the study) (T2) and after the 10-week intervention (T3). Level of statistical significance will be set at 5% (i.e. p < .05). The results of this trial will be submitted for publication in peer-reviewed journal. FINDINGS: The findings will provide evidence to determine whether physical exercise or melatonin supplement or the combination of interventions is the most effective to treat sleep disturbance in children with ASD.

Sarcopenia and its association with objectively measured life-space mobility and moderate-to-vigorous physical activity in the oldest-old amid the COVID-19 pandemic when a physical distancing policy is in force.

INTRODUCTION: The oldest-old are highly vulnerable to sarcopenia. Physical distancing remains a common and effective infection-control policy to minimize the risk of COVID-19 transmission during the pandemic. Sarcopenia is known to be associated with impaired immunity. Moderate-to-vigorous physical activity (MVPA) and life-space mobility (LSM) are potential strategies for minimizing the risk of sarcopenia. However, a physical distancing policy might jeopardize the practice of MVPA and LSM. The purposes of this study were to identify the prevalence of sarcopenia and examine the association between MVPA and LSM with sarcopenia in the community-dwelling oldest-old during the COVID-19 pandemic. METHODS: This study employed a cross-sectional and observational design. The study was conducted in 10 community centres for older people in Hong Kong during the period of the COVID-19 pandemic (September to December 2020). Eligible participants were the oldest-old people aged ≥85 years, who were community-dwelling and had no overt symptoms of cognitive impairment or depression. Key variables included sarcopenia as measured by SARC-F, LSM as measured by a GPS built into smartphones, and MVPA as measured by a wrist-worn ActiGraph GT3X+. Variables were described by mean and frequency. A multiple linear regression was employed to test the hypotheses. The dependent variable was sarcopenia and the independent variables included LSM and MVPA. RESULTS: This study recruited 151 eligible participants. Their mean age was 89.8 years and the majority of them were female (n = 93/151, 61.6%). The prevalence of sarcopenia was 24.5% (n = 37/151) with a margin of error of 6.86%. MVPA was negatively associated with sarcopenia in older people (ß = - 0.002, SE = 0.001, p = 0.029). However, LSM was not associated with sarcopenia. CONCLUSION: The prevalence of sarcopenia in the community-dwelling oldest-old population is high. MVPA is negatively associated with sarcopenia. LSM is unrelated to sarcopenia. Sarcopenia should be recognized and the oldest-old with sarcopenia should be accorded priority treatment during the COVID-19 pandemic.

Co-living with migrant domestic workers is associated with a lower level of loneliness among community-dwelling older adults: A cross-sectional study.

Loneliness (inclusive social loneliness and emotional loneliness) of older adults is a prominent public health issue internationally. Factors consistently associated with loneliness are age, gender, education, living arrangements, social network, and functional status. Intergenerational co-living with spouse and adult children is important for the exchange of social, emotional, practical, and financial support provided to older adults. Co-living with migrant domestic workers (MDWs) to care for older adults became an emergent phenomenon internationally, particularly in Asian countries. According to the convoy model of social relations, the effect of co-living with MDWs on older adults' loneliness is unknown. This study examined (1) the prevalence of loneliness among community-dwelling older adults; and (2) the association between co-living with MDWs and older adult loneliness. Using the Chinese version of the 6-item De Jong Gierveld Loneliness Scale on loneliness, 380 older adults were interviewed at busy points in Hong Kong, including subway stations. 35.3% of older adults experienced moderate-to-severe loneliness. Linear regression was performed to examine the association between co-living with MDWs and loneliness. The results showed that co-living with MDWs was significantly associated with lower levels of overall loneliness (ß = -0.636; p = .022) and emotional loneliness (ß = -0.298, p = .039), but not for social loneliness (ß = -0.337, p = .084). While MDWs could be an attachment figure for older adults, they might not be effective in promoting the social integration of older adults. There is a need to investigate the barriers of social integration faced by older adults co-living with MDWs.

Effect of a Telecare Case Management Program for Older Adults Who Are Homebound During the COVID-19 Pandemic: A Pilot Randomized Clinical Trial.

Importance: Older adults who are homebound can be difficult to reach owing to their functional limitations and social distancing during the COVID-19 pandemic, leaving their health needs unrecognized at an earlier stage. Objective: To determine the effectiveness of a telecare case management program for older adults who are homebound during the COVID-19 pandemic. Design, Setting, and Participants: This randomized clinical trial was conducted among 68 older adults in Hong Kong from May 21 to July 20, 2020, with a last follow-up date of October 20, 2020. Inclusion criteria were being 60 years or older, owning a smartphone, and going outside less than once a week in the previous 6 months. Interventions: Participants in the telecare group received weekly case management from a nurse supported by a social service team via telephone call and weekly video messages covering self-care topics delivered via smartphone for 3 months. Participants in the control group received monthly social telephone calls. Main Outcomes and Measures: The primary outcome was the change in general self-efficacy from before the intervention to after the intervention at 3 months. Self-efficacy was measured by the Chinese version of the 10-item, 4-point General Self-efficacy Scale, with higher scores representing higher self-efficacy levels. Analysis was performed on an intention-to-treat basis. Results: A total of 68 participants who fulfilled the criteria were enrolled (34 in the control group and 34 in the intervention group; 56 [82.4%] were women; and mean [SD] age, 71.8 [6.1] years). At 3 months, there was no statistical difference in self-efficacy between the telecare group and the control group. Scores for self-efficacy improved in both groups (ß = 1.68; 95% CI, -0.68 to 4.03; P = .16). No significant differences were found in basic and instrumental activities of daily living, depression, and use of health care services. However, the telecare group showed statistically significant interactions of group and time effects on medication adherence (ß = -8.30; 95% CI, -13.14 to -3.47; P = .001) and quality of life (physical component score: ß = 4.99; 95% CI, 0.29-9.69; P = .04). Conclusions and Relevance: In this randomized clinical trial, participants who received the telecare program were statistically no different from the control group with respect to changes in self-efficacy, although scores in both groups improved. After the intervention, the telecare group had better medication adherence and quality of life than the control group, although the small sample size may limit generalizability. A large-scale study is needed to confirm these results. Trial Registration: ClinicalTrials.gov Identifier: NCT04304989.

Face Mask Wearing Behaviors, Depressive Symptoms, and Health Beliefs Among Older People During the COVID-19 Pandemic.

The COVID-19 pandemic has affected more than 100 countries. Despite the global shortage of face masks, the public has adopted universal mask wearing as a preventive measure in many Asian countries. The COVID-19 mortality rate is higher among older people, who may find that wearing a face mask protects their physical health but jeopardizes their mental health. This study aimed to explore the associations between depressive symptoms, health beliefs, and face mask wearing behaviors among older people. By means of an online survey conducted between March and April 2020, we assessed depressive symptoms, health beliefs regarding COVID-19, and face mask use and reuse among community-dwelling older people. General linear models were employed to explore the associations among these variables. Of the 355 valid participants, 25.6% experienced depressive symptoms. Health beliefs regarding the perceived severity of disease (p = 0.001) and perceived efficacy of practicing preventive measures (p = 0.005) were positively associated with face mask use. Those who reused face masks (p = 0.008) had a stronger belief in disease severity (p < 0.001), had poorer cues to preventive measures (p = 0.002), and were more likely to experience depressive symptoms. Mask reuse was significantly associated with depression only among those who perceived the disease as serious (p = 0.025) and those who had poorer cues to preventive measures (p = 0.004). In conclusion, health beliefs regarding perceived severity and efficacy contributed to more frequent face mask use, which was unrelated to depressive symptoms. Older people who had a stronger belief in disease severity had less adequate cues to preventive measures and reused face masks experienced greater depressive symptoms. A moderation effect of health beliefs (i.e., disease severity and cues to preventive measures) on face mask reuse and depression was observed.

A validation study of the use of smartphones and wrist-worn ActiGraphs to measure physical activity at different levels of intensity and step rates in older people.

BACKGROUND: Physical activity promotes healthy ageing in older people. Accurate measurement of physical activity in free-living environment is important in evaluating physical activity interventions. RESEARCH QUESTION: What is the criterion validity of 1)an ActiGraph to identify physical activity at different intensity levels and 2)an ActiGraph and a smartphone to measure step rate? METHODS: Community-dwelling older people aged≥60 were recruited. The index tests were using ActiGraph worn in different positions (i.e.,both wrists and hip) to measure physical activity intensity and step rate and using smartphone (i.e., Samsung J2 pro and Google Fit) worn in different positions (i.e.,trousers pocket and waist pouch) to measure the step rate. The reference standards were using indirect calorimetry (i.e.,CosMedK4b 2) to measure physical activity intensity and using direct observation for step rate. Subjects were exposed in different physical activity intensity levels (i.e.,sedentary:MET < 1.5,light: MET = 1.5-2.99, moderate:MET = 3.0-6.0, vigorous:MET>6) and step rates through walking on a treadmill at different speeds (i.e.,2-8 km) for approximately 30 min. Spearman's rho, ROC analysis, and percentage error were employed to report the criterion validity. RESULTS: 31 participants completed the tests. ActiGraphs worn in different body positions could significantly differentiate physical activity intensity at the levels of "light- or-above" (VM cut-off = 279.5-1959.1,AUC = 0.932-0.954), "moderate-or-above" (VM cut- off = 1051.0-4212.9,AUC = 0.918-0.932), and "vigorous" (VM cut-off = 3335.4-5093.0, AUC = 0.890-0.907) well with different cut-off points identified. The step rate measured by direct observation correlated significantly with ActiGraph and smartphone (rho = 0.415-0.791). Both ActiGraph and smartphone at different positions generally underestimated the step rate (%error= -20.5,-30.3). SIGNIFICANCE: A wrist-worn ActiGraph can accurately identify different physical activity intensity levels in older people, but lower cut-off points in older people should be adopted. To measure step rate, a hip-mounted ActiGraph is preferable than a wrist- worn one. A smartphone employing Google Fit generally underestimates step rate but it gives a relatively more accurate estimation of step rate when the older people walk at a speed of 4-8 km/h.

Prevalence of sleep disturbances during COVID-19 outbreak in an urban Chinese population: a cross-sectional study.

OBJECTIVE: The COVID-19 pandemic is a large-scale public health emergency that likely precipitated sleep disturbances in the community. This study aimed to investigate the prevalence and correlates of sleep disturbances during the early phase of COVID-19 pandemic. METHODS: This web-based cross-sectional study recruited 1138 Hong Kong adults using convenience sampling over a two-week period from 6th April 2020. The survey collected data on sleep disturbances, mood, stress, stock of infection control supplies, perceived risk of being infected by COVID-19, and sources for acquiring COVID-19 information. The participants were asked to compare their recent sleep and sleep before the outbreak. The Insomnia Severity Index (ISI) was used to assess their current insomnia severity. Prevalence was weighted according to 2016 population census. RESULTS: The weighted prevalence of worsened sleep quality, difficulty in sleep initiation, and shortened sleep duration since the outbreak were 38.3%, 29.8%, and 29.1%, respectively. The prevalence of current insomnia (ISI score of ≥10) was 29.9%. Insufficient stock of masks was significantly associated with worsened sleep quality, impaired sleep initiation, shortened sleep duration, and current insomnia in multivariate logistic regression (adjusted OR = 1.57, 1.72, 1.99, and 1.96 respectively, all p < 0.05). CONCLUSION: A high proportion of people in Hong Kong felt that their sleep had worsened since the COVID-19 outbreak. Insufficient stock of masks was one of the risk factors that were associated with sleep disturbances. Adequate and stable supply of masks may play an important role to maintain the sleep health in the Hong Kong general population during a pandemic outbreak.

The diversified defocus profile of the near-work environment and myopia development.

PURPOSE: To quantify the defocus characteristics in the near-work environment at home and investigate the relationship with subsequent myopia progression. METHODS: Fifty subjects (aged 7-12 years) were recruited and followed for 1 year. The home near-work environment (writing desk) was measured at a baseline home-visit using the Kinect-for-Windows to capture a 3-dimensional image. The depth values of the image were then converted into scene defocus with respect to the subject's viewpoint. The defocus characteristics were quantified as the dioptric volume (the total amount of net defocus, or DV) and standard deviation of the defocus values (SDD ). Information on home size, time spent outdoors, and in front of a desk were also obtained. Univariate correlation, and multivariate regression were used to assess the association between myopia progression, defocus characteristics, and other co-variates. RESULTS: The baseline spherical equivalent refraction (M) and refraction change over 1 year (∆M) were - 1.51 ± 2.02 D and - 0.56 ± 0.45 D respectively. DV was not significantly correlated with ∆M (Spearman's ρ = -0.25, p = 0.08), while SDD was negatively correlated to ∆M (Spearman's ρ = -0.42, p = 0.003). Although SDD was not a significant predictor in multivariate analysis, the regional DV at 15°-20° eccentricity was significant (p = 0.001). Home size (F2,50  = 7.01, p = 0.002) and time spent outdoors (Independent t = -2.13, p = 0.04) were also associated with ∆M, but not time spent in front of desk (Independent t = 0.78, p = 0.44). CONCLUSION: The defocus profile in the home environment within the para-central field of view is associated with childhood refractive error development.

An exploration of the use of visually appealing contexts in a pain management program.

PURPOSE: Pleasant pictures can help to reduce stress, promote positive feelings, and even facilitate recovery from diseases. Visual stimulation is an approach of distraction that can effectively reduce pain thresholds and increase pain tolerances. The number of older adults who suffer from pain has increased due to age-related diseases. Technology is increasingly being applied to the management of acute pain. The pain situation among older people was explored in this study, and a visually appealing pain management program was designed with the participants' experiences in mind. METHODS: This was a descriptive observational study. Participants were recruited from local nursing homes. RESULTS: A total of 165 older adults joined the study. The mean age of the participants was 85.6. More female than male participants experienced pain and the intensity of their pain was significantly greater. The results showed no significant differences in pain interferences between males and females. The participants stated that photographs of family members, homes, and natural scenery made them feel relaxed and happy, and reminded them of past happy times. They preferred to view those visually appealing pictures using digital devices (iPad/iPhone) to seeing hard copy versions. CONCLUSION: A digital-based pain management program using visually appealing contexts for older adults can be implemented. The patients' experiences were collected and will be considered when developing a future program.

The effect of e-health interventions promoting physical activity in older people: a systematic review and meta-analysis.

INTRODUCTION: The objectives of this review paper were to synthesize the data from randomized controlled trials in the literature to come to a conclusion on the effects of e-health interventions on promoting physical activity in older people. METHODS: The Medline, CINAHL, Embase, PsycINFO, and SportDiscus databases were searched for articles about studies that 1) recruited subjects with a mean age of > 50 years, 2) tested e-health interventions, 3) employed control groups with no or less advanced e-health strategies, 4) measured physical activity as an outcome, 5) were published between 1st January 2008 and 31st May 2019, and 6) employed randomized controlled trials. The risk of bias in individual studies was assessed using the Physiotherapy Evidence Database scale. To examine the effects of the interventions, variables quantifying the amount of physical activity were extracted. The within-group effects of individual studies were summarized using Hedges g and 95% confidence intervals. Between-group effects were summarized by meta-analyses using RevMan 5.0 with a random effect model. RESULTS: Of the 2810 identified studies, 38 were eligible, 25 were included in the meta-analyses. The within-group effect sizes (Hedges g) of physical activity in the intervention group at T1 ranged from small to large: physical activity time (0.12 to 0.84), step counts (- 0.01 to 11.19), energy expenditure (- 0.05 to 0.86), walking time (0.13 to 3.33), and sedentary time (- 0.12 to - 0.28). The delayed effects as observed in T2 and T3 also ranged from small to large: physical activity time (0.24 to 1.24) and energy expenditure (0.15 to 1.32). In the meta-analysis, the between-group effect of the e-health intervention on physical activity time measured by questionnaires, physical activity time measured by objective wearable devices, energy expenditure, and step counts were all significant with minimal heterogeneity. CONCLUSION: E-health interventions are effective at increasing the time spent on physical activity, energy expenditure in physical activity, and the number of walking steps. It is recommended that e-health interventions be included in guidelines to enhance physical activity in older people. Further studies should be conducted to determine the most effective e-health strategies.

Global Imperative of Suicidal Ideation in 10 Countries Amid the COVID-19 Pandemic.

Background: The novel coronavirus (COVID-19) has had a detrimental impact on individuals' psychological well-being; however, a multi-country comparison on the prevalence of suicidal ideation due to the virus is still lacking. Objectives: To examine the prevalence and correlates of suicidal ideation among the general population across 10 countries during the COVID-19 pandemic. Materials and methods: This was a cross-sectional study which used convenience sampling and collected data by conducting an online survey. Participants were sourced from 10 Eastern and Western countries. The Patient Health Questionnaire (PHQ-9) was used to measure the outcome variable of suicidal ideation. Ordinal regression analysis was used to identify significant predictors associated with suicidal ideation. Results: A total of 25,053 participants (22.7% male) were recruited. Results from the analysis showed that the UK and Brazil had the lowest odds of suicidal ideation compared to Macau (p < 0.05). Furthermore, younger age, male, married, and differences in health beliefs were significantly associated with suicidal ideation (p < 0.05). Conclusions: The findings highlight the need for joint international collaboration to formulate effective suicide prevention strategies in a timely manner and the need to implement online mental health promotion platforms. In doing so, the potential global rising death rates by suicide during the pandemic can be reduced.

Symptom Clusters in Postchemotherapy Neutropenic Fever in Hematological Malignancy: Associations Among Sickness Behavior Symptom Cluster, Inflammatory Biomarkers of Procalcitonin and C-Reactive Protein, and Febrile Measures.

CONTEXT: Little research has been conducted to investigate symptom clusters in postchemotherapy neutropenic fever (NF), their relationships with inflammatory biomarkers, and febrile outcome measures in patients with hematological malignancy, a population with high febrile rates incurring considerable costs to the health care system. OBJECTIVES: The aim of the present study was to investigate these. METHODS: One hundred four NF episodes were observed in patients with hematological malignancy who were enrolled in the study. Patient-reported symptoms were recorded using the M.D. Anderson Symptom Inventory. Inflammatory biomarkers of procalcitonin (PCT) and C-reactive protein (CRP), vital signs, blood specimens for cultures, blood cell counts, and biochemistry were also collected. Serious complications from NF were reviewed from medical records if documented. Exploratory factor analysis and Spearman's rank correlation were used in the data analysis. RESULTS: Three symptom clusters-sickness behavior, chemotherapy neurotoxicity, and emesis-were identified by exploratory factor analysis. The factor score of the sickness behavior cluster was significantly correlated with CRP (P < 0.05), PCT (P < 0.01), and the highest (P < 0.05) and maximum increased in (P < 001) temperatures at the onset (first day) of neutropenic fever. CONCLUSION: This study identified symptom clusters of sickness behavior, chemotherapy neurotoxicity, and emesis and highlighted significant associations between sickness behavior cluster, PCT, CRP, and febrile temperatures at the onset of postchemotherapy NF. These areas have lacked exploration in previous research. Monitoring and analyzing patient-reported sickness behavior symptoms, PCT, CRP, and temperature data would provide significant complementary data for the management and surveillance of postchemotherapy NF in hematological malignancy.

Lesson Learned from Peer Volunteers in a Peer-Led Pain Management Program among Nursing Home Residents.

BACKGROUND: Chronic pain is common among older adults and is associated with adverse physical and psychological outcomes. Given the burden of pain and limited healthcare resources, devising innovative and cost-effective ways of managing chronic pain is of high priority. The aim of this paper is to explore the experiences and perceptions of peer volunteers (PVs) in a peer-led pain management program among nursing home residents in Hong Kong. METHODS: Forty-six PVs were recruited and trained to lead a pain management program (PAP). The PAP consisted of one 1 hour session per week for 12 weeks. It included 20 min of physical exercises performed under the supervision of PVs, followed by 30 min of pain management education, including information on pain situations, the impacts of pain, the use of drugs and non-drug strategies for pain management, demonstrations, and return demonstrations of various non-drug pain management techniques. Quantitative data were collected from questionnaires (demographics, pain situation, and pain knowledge) for all PVs. Qualitative data (PVs' experiences in leading the PAP, their perceived benefits, barriers encountered, and recommendations for improving the PAP) were collected at week 12 (upon completion of the PAP). Data were analyzed using the Statistical Package for Social Sciences and content analysis for qualitative data. RESULTS: A total of 46 PVs were recruited (34 females, 74%), with a mean ± SD age of 61.0 ± 5.1 years. Thirty-one of them reported having chronic pain. Before the training, their self-rated pain knowledge was 40.0 ± 20.5 (maximum 100 points) while their actual pain knowledge score was 86.1 ± 10.6 (maximum 100 points). The PVs reported an improvement in their knowledge and skills after leading PAPs. No PVs reported having received any negative comments about their role in leading the PAP but mentioned that they had received feedback on how to improve the program. CONCLUSIONS: This study provides further evidence that peer-led pain management programs are feasible and can lead to positive experiences for the PVs. Peer support models are coming into wide use because they show promise in helping patients to manage chronic conditions. Peer volunteers will become important resources in elderly care. The barriers that were identified may lead to improvements in the design and planning of future PAPs.

Childhood exposure to constricted living space: a possible environmental threat for myopia development.

PURPOSE: People in Hong Kong generally live in a densely populated area and their homes are smaller compared with most other cities worldwide. Interestingly, East Asian cities with high population densities seem to have higher myopia prevalence, but the association between them has not been established. This study investigated whether the crowded habitat in Hong Kong is associated with refractive error among children. METHODS: In total, 1075 subjects [Mean age (S.D.): 9.95 years (0.97), 586 boys] were recruited. Information such as demographics, living environment, parental education and ocular status were collected using parental questionnaires. The ocular axial length and refractive status of all subjects were measured by qualified personnel. RESULTS: Ocular axial length was found to be significantly longer among those living in districts with a higher population density (F2,1072  = 6.15, p = 0.002) and those living in a smaller home (F2,1072  = 3.16, p = 0.04). Axial lengths were the same among different types of housing (F3,1071  = 1.24, p = 0.29). Non-cycloplegic autorefraction suggested a more negative refractive error in those living in districts with a higher population density (F2,1072  = 7.88, p < 0.001) and those living in a smaller home (F2,1072  = 4.25, p = 0.02). After adjustment for other confounding covariates, the population density and home size also significantly predicted axial length and non-cycloplegic refractive error in the multiple linear regression model, while axial length and refractive error had no relationship with types of housing. CONCLUSIONS: Axial length in children and childhood refractive error were associated with high population density and small home size. A constricted living space may be an environmental threat for myopia development in children.
