Association of Depression With the Progression of Multimorbidity in Older Adults: A Population-Based Cohort Study.

BACKGROUND: The relationship between depression and the risk of multimorbidity progression has rarely been studied in older adults. This study was aimed to determine whether depression is associated with progression in the severity and complexity of multimorbidity, considering the influence of depression's severity and subtype. METHODS: As a part of the Korean Longitudinal Study on Cognitive Aging and Dementia, this population-based cohort study followed a random sample of community-dwelling Koreans aged 60 and older for 8 years at 2-year intervals starting in 2010. Participants included those who completed mood and multimorbidity assessments and did not exhibit complex multimorbidity at the study's outset. Depression was assessed using the Geriatric Depression Scale, while multimorbidity was evaluated using the Cumulative Illness Rating Scale. The study quantified multimorbidity complexity by counting affected body systems and measured multimorbidity severity by averaging scores across 14 body systems. FINDINGS: The 2,486 participants (age = 69.1 ± 6.5 years, 57.6% women) were followed for 5.9 ± 2.4 years. Linear mixed models revealed that participants with depression had a faster increase in multimorbidity complexity score (ß = .065, SE = 0.019, p = 0.001) than those without depression, but a comparable increase in multimorbidity severity score (ß = .001, SE = .009, p = 0.870) to those without depression. Cox proportional hazard models revealed that depression was associated with the risk of developing highly complex multimorbidity affecting five or more body systems, particularly in severe or anhedonic depression. INTERPRETATION: Depression was associated with the worsening of multimorbidity in Korean older adults, particularly when severe or anhedonic. Early screening and management of depression may help to reduce the burden of multimorbidity in older adults.

Biomarkers of Waterpipe Tobacco Smoke Exposure: A Systematic Review and Meta-Analysis.

INTRODUCTION: The prevalence of waterpipe tobacco smoking is increasing globally. Biomarkers of waterpipe tobacco smoke (WTS) exposure are less studied. AIMS AND METHODS: To identify the types of biomarkers of WTS exposure and estimate changes in biomarker concentrations pre- to post-WTS exposure. PubMed, Embase, Web of Science, CINAHL Plus, PsycINFO, and Cochrane Library were searched for studies up to April 24, 2023. The types of biomarkers were identified. Random-effects models were used to estimate changes in biomarker concentrations pre- to post-WTS exposure. RESULTS: Seventy-three studies involving 3755 participants exposed to WTS (49% male, mean age: 24.8 years) and 11 types of biomarkers of WTS exposure were identified. The biomarkers included tobacco alkaloids, expired carbon monoxide (eCO), carboxyhemoglobin (COHb), tobacco-specific nitrosamines, volatile organic compounds (VOCs), polycyclic aromatic hydrocarbons (PAHs), heavy metals, unmetabolized VOCs, unmetabolized PAHs, furan metabolites, and heterocyclic aromatic amines. Compared with pre-WTS exposure, eCO (breath; mean difference [MD] 27.00 ppm; 95% confidence interval [CI]: 20.91 to 33.08), COHb (blood; MD 4.30%; 95%CI: 2.57 to 6.03), COHb (breath; MD 7.14%; 95%CI: 4.96 to 9.31), nicotine (blood; MD 8.23 ng/mL; 95%CI: 6.27 to 10.19), and cotinine (urine; MD 110.40 ng/mL; 95%CI: 46.26 to 174.54) significantly increased post-WTS exposure. CONCLUSIONS: Biomarkers of WTS exposure were systematically identified. The similarity between the biomarkers of WTS exposure and those of cigarette smoke and higher concentrations of some biomarkers post-WTS exposure underscore the need for further research on applying biomarkers in surveillance, interventions, and regulations to mitigate the harms of waterpipe tobacco smoking. IMPLICATIONS: This study provides the first comprehensive overview of biomarkers investigated and available for assessing WTS exposure and their concentration changes in the human body. Researchers can use biomarkers such as eCO, COHb, nicotine, and cotinine to measure the health risks associated with WTS exposure and objectively evaluate the effectiveness of public health interventions aimed at reducing waterpipe tobacco smoking. Public health policymaking can also be informed through increased biomarker concentrations following WTS exposure, to implement regulations and public health education campaigns on limiting or preventing waterpipe tobacco smoking.

Perceptions of and responses of young adults who use e-cigarettes to flavour bans in China: a qualitative study.

BACKGROUND: China has banned all flavoured e-cigarettes to reduce e-cigarette use among young people, but little is known about the views and reactions of people who use e-cigarettes. This study explored the perceptions of, and responses by, young adults who use e-cigarettes to the flavour ban. METHODS: Semistructured interviews were conducted with 25 Chinese young adults aged 18-25 years who had used e-cigarettes daily in the past 3 months. Thematic analysis was used to analyse the interview data. FINDINGS: Four themes were identified from the data: (1) understanding of the public health benefits, (2) resistance to and misperceptions of the flavour ban, (3) circumvention of the flavour ban and (4) acceptance of the flavour ban. Some participants expressed support for the ban due to perceived public health benefits, while others who resisted the ban emphasised their right to choose preferred flavours and questioned the rationale behind the policy. Participants responded to the flavour ban by utilising a variety of adaptive strategies, including purchasing flavoured e-cigarettes through illegal channels or exploring alternative ways to obtain flavours. Those who complied with the ban responded with different strategies, including switching back to combustible cigarettes, using tobacco-flavoured e-cigarettes, or quitting vaping. CONCLUSIONS: The findings suggest the need for comprehensive regulatory measures, including stringent enforcement measures, transparent health communication and vigilant monitoring of e-cigarette manufacturers' tactics, to reduce e-cigarette use among young adults.

Prevalence and Factors Associated With Willingness to Sustain Pandemic-Induced Digital Work in the General Population and Moderating Effects of Screen Hours: Cross-Sectional Study.

BACKGROUND: The pandemic has accelerated digital work transformation, yet little is known about individuals' willingness to sustain such digital modes and its associated factors. A better understanding of this willingness and its drivers is crucial for guiding the development of future digital work infrastructure, training programs, and strategies to monitor and prevent related health issues. OBJECTIVE: This study aims to quantify the general population's willingness to sustain pandemic-induced digital work, identify its associated factors, and examine how screen time moderates these relationships. METHODS: A cross-sectional study was conducted targeting Hong Kong residents aged ≥18 years who have increased engagement in digital work since the pandemic. Data were collected through self-reported, web-based surveys. Descriptive statistics determined prevalence rates, while structured multiphase logistic regression identified associated factors and explored the moderating effects of screen hour levels. RESULTS: This unfunded study enrolled 1014 participants from May 2 to June 24, 2022, and completed data analysis within 3 months after data collection. A total of 391 (38.6%; 95% CI 35.6%-41.6%) participants expressed willingness to sustain digital work. Positive factors associated with this willingness included being an employee (odds ratio [OR] 3.12, 95% CI 1.59-6.45; P=.001), being health professionals (OR 3.32, 95% CI 1.49-7.82; P=.004), longer screen hours (OR 1.09, 95% CI 1.03-1.15; P=.002), and higher depression levels (OR 1.20, 95% CI 1.01-1.44; P=.04). Conversely, negatively associated factors included older age (OR 0.87, 95% CI 0.81-0.94; P=.001), extroversion (OR 0.66, 95% CI 0.51-0.86; P=.002), higher eHealth literacy (OR 0.96, 95% CI 0.93-0.98; P<.001), perceived greater susceptibility to COVID-19 (OR 0.84, 95% CI 0.74-0.96; P=.009), residence in a high-severity COVID-19 community (OR 0.73, 95% CI 0.63-0.84; P<.001), having infected individuals in the immediate social circle (OR 0.64, 95% CI 0.46-0.88; P=.006), higher BMI (OR 0.94, 95% CI 0.90-0.99; P=.02), feelings of being out of control (OR 0.96, 95% CI 0.93-0.98; P=.002), and higher fear of COVID-19 (OR 0.96, 95% CI 0.94-0.98; P=.001). In addition, a moderating effect of screen hour level (high: >8 h/d; low: ≤8 h/d) influenced the association among 10 factors related to willingness to sustain pandemic-induced digital work, including age, education level, household size, needs for regular medical care, BMI, frequency of both vigorous and moderate physical activities, perceived COVID-19 severity, immediate social circle COVID-19 presence, and fear of COVID-19 (all P values for interaction <.05). CONCLUSIONS: The substantial willingness of the general population to sustain digital work after the pandemic highlights the need for robust telework infrastructure, thorough monitoring of adverse health outcomes, and the potential to expand telehealth services among this group. The identification of factors influencing this willingness and the moderating role of screen hours inform the development of personalized strategies to enhance digital work acceptance where needed.

Menstrual and psychosocial characteristics associated with high-risk of premenstrual dysphoric disorder among university students: a cross-sectional study.

Up to 92 percent of Chinese women of reproductive age have pre-menstrual syndrome (PMS). The severe form of PMS (i.e. pre-menstrual dysphoric disorder [PMDD]) negatively affects women's everyday functioning and reproductive health. This study examined the relationships between menstrual, psychosocial characteristics and the risk of PMDD among young Chinese women. A cross-sectional online survey was conducted among Chinese university students in Hong Kong. Logistic regression was used to compute adjusted odds ratio (aOR) for the association of high-risk PMDD with menstrual and psychosocial characteristics. A total of 541 Chinese university students were recruited. Approximately 53 percent of female students were at high risk of developing PMDD. The high-risk PMDD group was significantly associated with a heavy volume of menstrual flow (aOR = 2.17, 95 percent CI 1.06-4.45), irregular menstrual cycle (1.72, 1.17-2.52), high dysmenorrhea (2.80, 1.95-4.04) and older ages of menarche (0.67, 0.45-0.98) in the menstrual characteristics. In the psychosocial characteristics, high-risk PMDD was significantly associated with symptoms of anxiety (2.19, 1.48-3.32) and depression (2.22, 1.48-3.32), high loneliness (1.94, 1.34-2.79) and low resilience (2.21, 1.52-3.23) levels. Additionally, resilience had a potential moderating effect on the associations between the high risk of PMDD and anxiety, depression and loneliness. The development and delivery of interventions that can enhance resilience and manage psychological distress would be beneficial for young Chinese women's reproductive health.

Stroke caregivers' perception on instant messaging application use for psychological intervention: a qualitative study.

In caring for patients with stroke, the leading cause of death and disability affecting over 80 million people worldwide, caregivers experience substantial psychological and physical burdens and difficulties in help-seeking owing to physical and time-constraints. Social distancing measures imposed during the coronavirus disease 2019 (COVID-19) pandemic further restricted them from using caregiver support services. While the use of telehealth emerged as a global prevailing trend during the COVID-19 pandemic, evidence for utilising instant messaging (IM) applications for psychological intervention is scanty. This study aimed to explore stroke caregivers' perceived potential utility of IM-delivered psychological intervention. Between January and August 2020, 36 adult family stroke caregivers in Hong Kong were recruited to individual telephone semi-structured interviews using purposive sampling. The interviews were audio-recorded, transcribed verbatim and analysed using an interpretive description approach. Three themes of caregivers' perceptions towards IM-delivered psychological intervention emerged: perceived high convenience and ease of use, perceived advantages that overcome existing barriers to services and message delivery tailored to individual needs. Our findings suggested that there is an imminent need among stroke caregivers for personalised psychological interventions and that IM is a potential modality for overcoming existing barriers in delivering accessible support to caregivers in real-time, real-world settings. Our study highlighted caregivers' acceptance and perceived benefits of IM-delivered psychological intervention and provided practical insights into the design of IM-delivered psychological interventions.

What is the impact of one's chronic illness on his or her spouse's future chronic illness: a community-based prospective cohort study.

BACKGROUND: Integrating a joint approach to chronic disease management within the context of a couple has immense potential as a valuable strategy for both prevention and treatment. Although spousal concordance has been reported in specific chronic illnesses, the impact they cumulatively exert on a spouse in a longitudinal setting has not been investigated. We aimed to determine whether one's cumulative illness burden has a longitudinal impact on that of their spouse. METHODS: Data was acquired from a community-based prospective cohort that included Koreans aged 60 years and over, randomly sampled from 13 districts nationwide. Data from the baseline assessment (conducted from November 2010 to October 2012) up to the 8-year follow-up assessment was analyzed from October 2021 to November 2022. At the last assessment, partners of the index participants were invited, and we included 814 couples in the analysis after excluding 51 with incomplete variables. Chronic illness burden of the participants was measured by the Cumulative Illness Rating Scale (CIRS). Multivariable linear regression and causal mediation analysis were used to examine the longitudinal effects of index chronic illness burden at baseline and its change during follow-up on future index and spouse CIRS scores. RESULTS: Index participants were divided based on baseline CIRS scores (CIRS < 6 points, n = 555, mean [SD] age 66.3 [4.79] years, 43% women; CIRS ≥ 6 points, n = 259, mean [SD] age 67.7 [4.76] years, 36% women). The baseline index CIRS scores and change in index CIRS scores during follow-up were associated with the spouse CIRS scores (ß = 0.154 [SE: 0.039], p < 0.001 for baseline index CIRS; ß = 0.126 [SE: 0.041], p = 0.002 for change in index CIRS) at the 8-year follow-up assessment. Subgroup analysis found similar results only in the high CIRS group. The baseline index CIRS scores and change in index CIRS scores during follow-up had both direct and indirect effects on the spouse CIRS scores at the 8-year follow-up assessment. CONCLUSIONS: The severity and course of one's chronic illnesses had a significant effect on their spouse's future chronic illness particularly when it was severe. Management strategies for chronic diseases that are centered on couples may be more effective.

The impact of the COVID-19 pandemic on depression in community-dwelling older adults: a prospective cohort study.

BACKGROUND: There are growing concerns about the impact of the COVID-19 pandemic on the mental health of older adults. We examined the effect of the pandemic on the risk of depression in older adults. METHODS: We analyzed data from the prospective cohort study of Korean older adults, which has been followed every 2 years. Among the 2308 participants who completed both the third and the fourth follow-up assessments, 58.4% completed their fourth follow-up before the outbreak of COVID-19 and the rest completed it during the pandemic. We conducted face-to-face diagnostic interviews using Mini International Neuropsychiatric Interview and used Geriatric Depression Scale. We performed generalized estimating equations and logistic regression analyses. RESULTS: The COVID-19 pandemic was associated with increased depressive symptoms in older adults [b (standard error) = 0.42 (0.20), p = 0.040] and a doubling of the risk for incident depressive disorder even in euthymic older adults without a history of depression (odds ratio = 2.44, 95% confidence interval 1.18-5.02, p = 0.016). Less social activities, which was associated with the risk of depressive disorder before the pandemic, was not associated with the risk of depressive disorder during the pandemic. However, less family gatherings, which was not associated with the risk of depressive disorder before the pandemic, was associated with the doubled risk of depressive disorder during the pandemic. CONCLUSIONS: The COVID-19 pandemic significantly influences the risk of late-life depression in the community. Older adults with a lack of family gatherings may be particularly vulnerable.

Evidence of risky driving in Korean older adults: A longitudinal cohort.

OBJECTIVES: The aim of this study was to determine the differences in the risk factors for dangerous driving between older adults with normal cognition and those with cognitive impairment. DESIGN: The driving risk questionnaire (DRQ) that was applied to a community-dwelling older adult cohort and 2 years of accident/violation records from the National Police Agency were analyzed. We conducted regression analyses with the presence or absence of risky driving based on records (accidents + violations) 2 years before and after evaluation as a dependent variable and dichotomized scores of each risky driving factor as independent variables. RESULTS: According to four identified factors-crash history, safety concern, reduced mileage, and aggressive driving-significant associations were found between risky driving over the past 2 years and crash history and for aggressive driving in the normal cognition group. In the cognitive impairment group, only crash history was significantly associated, although safety concerns showed a trend toward significance. CONCLUSIONS: In this study, it was suggested that the factors of DRQ have a significant association with actual risky driving. Our results are expected to contribute to establishing the evidence for evaluating and predicting risky driving and advising whether to continue driving in clinics.

Circumventing tobacco control and safety policies to promote waterpipe use in smoking venues: the perspective of staff in waterpipe smoking venues.

OBJECTIVE: To understand Hong Kong waterpipe smoking (WPS) sales and promotion, including strategies to avoid policy enforcement, from the perspective of WPS venue staff. METHODS: Qualitative interviews and observations were guided by interpretive description. 20 WPS venue staff who were responsible for preparing and serving waterpipes to patrons and had worked at the bar for at least 3 months were recruited. In-depth semistructured interviews with WPS venue staff were conducted, in addition to covert and participant observations in 10 WPS venues in Hong Kong. Interpretive description involving constant comparative analysis of qualitative data was adopted to facilitate an inductive analytic approach to generate findings. RESULTS: Two primary themes emerged from analyses of interview and observation data: strategies to avoid law enforcement, and perceived health and safety concerns linked to working and smoking in waterpipe venues. The findings suggest that many Hong Kong venues may be failing to comply with tobacco control policies and developing strategies to circumvent law enforcement. Moreover, waterpipe preparation, allowance of WPS and burning of charcoal in indoor areas were perceived as negatively affecting the health and safety of staff and customers. CONCLUSIONS: The study provides preliminary evidence indicating the ineffectiveness of current tobacco control policy on WPS. Due to its risks to health and safety, and the need to sustain tobacco control efforts for their intended purpose, waterpipe-specific regulations and stricter surveillance on waterpipe sales and promotion are urgently required.

Associations between older adults' social media use behaviors and psychosocial well-being.

BACKGROUND: Research examining associations between social media use behaviors and psychosocial well-being among older adults are limited. AIMS: To explore associations between older adults' social media (social networking services and instant messaging applications) use behaviors and psychosocial well-being. METHODS: This was a secondary data analysis. All data were retrieved from the Taiwan Communication Survey database, an annual survey that examines trends in Taiwanese residents' communication behaviors and social media use. The original investigation was conducted in Taiwan from September to December 2019. Data from 647 older adults aged over 60 years were extracted for the analyses. Social media use behaviors (users/non-users and time spent using), positive psychosocial outcomes (life satisfaction, self-determination, subjective well-being, and happiness), negative psychosocial outcomes (loneliness, depression, and anxiety), and demographic variables were included. RESULTS: Social media users had significantly higher levels of subjective well-being and lower levels of depression, anxiety, and loneliness compared with non-users. Time spent on social networking services was significantly and positively correlated with negative psychosocial outcomes (ß = 0.103, p = 0.044, f2 = 0.011), and it was significantly and inversely correlated with positive psychosocial outcomes (ß = - 0.063, p = 0.049, f2 = 0.004). Time spent using an instant messaging application was significantly positively associated with positive psychosocial outcomes (ß = 0.068, p = 0.031, f2 = 0.005). The proposed path model had an acceptable model fit. DISCUSSION: Study results indicated that older adults' social media use behaviors were associated with their psychosocial well-being. CONCLUSIONS: Older adults are recommended to use social media for appropriate time periods as an important way to promote social engagement for their psychosocial well-being.

Parental history of dementia and the risk of dementia: A cross-sectional analysis of a global collaborative study.

BACKGROUND: Parental history of dementia appears to increase the risk of dementia, but there have been inconsistent results. We aimed to investigate whether the association between parental history of dementia and the risk of dementia are different by dementia subtypes and sex of parent and offspring. METHODS: For this cross-sectional study, we harmonized and pooled data for 17,194 older adults from nine population-based cohorts of eight countries. These studies conducted face-to-face diagnostic interviews, physical and neurological examinations, and neuropsychological assessments to diagnose dementia. We investigated the associations of maternal and paternal history of dementia with the risk of dementia and its subtypes in offspring. RESULTS: The mean age of the participants was 72.8 ± 7.9 years and 59.2% were female. Parental history of dementia was associated with higher risk of dementia (odds ratio [OR] = 1.47, 95% confidence interval [CI] = 1.15-1.86) and Alzheimer's disease (AD) (OR = 1.72, 95% CI = 1.31-2.26), but not with the risk of non-AD. This was largely driven by maternal history of dementia, which was associated with the risk of dementia (OR = 1.51, 95% CI = 1.15-1.97) and AD (OR = 1.80, 95% CI = 1.33-2.43) whereas paternal history of dementia was not. These results remained significant when males and females were analyzed separately (OR = 2.14, 95% CI = 1.28-3.55 in males; OR = 1.68, 95% CI = 1.16-2.44 for females). CONCLUSIONS: Maternal history of dementia was associated with the risk of dementia and AD in both males and females. Maternal history of dementia may be a useful marker for identifying individuals at higher risk of AD and stratifying the risk for AD in clinical trials.

Perceptions and experiences of sexual violence among Chinese men who have sex with men in Hong Kong.

AIM: This study aimed to understand the perceptions and experiences of sexual violence among Chinese men who have sex with men (MSM) in Hong Kong. DESIGN: The study adopted a qualitative descriptive design with thematic analysis. METHODS: Thirty-one Chinese MSM were recruited in Hong Kong from May to June 2019 using purposive sampling. Individual semi-structured interviews were conducted with the participants. The interview data were transcribed verbatim from the recordings and analysed using Braun and Clarke's thematic analysis approach. RESULTS: Four themes were identified: (1) different forms of sexual violence, from physical to virtual; (2) inner struggles with fears and worry; (3) low awareness and perceived risk of sexual violence - 'it has nothing to do with me' and (4) dilemma towards sexual violence prevention. CONCLUSION: The study provided qualitative evidence regarding the experiences and perceptions of sexual violence among Chinese MSM in Hong Kong. Physical and image-based forms of sexual violence were identified, which led the participants to experience psychological distress, fear of contracting human immunodeficiency virus/other sexually transmitted infections, notoriety within the gay community, and discrimination and stigmatization within their family and workplace. To reduce the risk of sexual violence, some participants were cautious about the venue in which they engaged in sex and the habit of sharing sexually explicit photos with others. However, some participants had low awareness and perceived risk of sexual violence. IMPACTS: This study was the first to fill the research gap on sexual violence issues among Chinese MSM using dating apps in Hong Kong. The qualitative findings enhanced the scholarly understanding of Chinese MSM's perceptions and experiences of sexual violence. The study findings can help nursing staff and other healthcare professionals to develop tailored primary, secondary and tertiary sexual violence prevention programmes for MSM or beyond.

Artificial intelligence in nursing and midwifery: A systematic review.

BACKGROUND: Artificial Intelligence (AI) techniques are being applied in nursing and midwifery to improve decision-making, patient care and service delivery. However, an understanding of the real-world applications of AI across all domains of both professions is limited. OBJECTIVES: To synthesise literature on AI in nursing and midwifery. METHODS: CINAHL, Embase, PubMed and Scopus were searched using relevant terms. Titles, abstracts and full texts were screened against eligibility criteria. Data were extracted, analysed, and findings were presented in a descriptive summary. The PRISMA checklist guided the review conduct and reporting. RESULTS: One hundred and forty articles were included. Nurses' and midwives' involvement in AI varied, with some taking an active role in testing, using or evaluating AI-based technologies; however, many studies did not include either profession. AI was mainly applied in clinical practice to direct patient care (n = 115, 82.14%), with fewer studies focusing on administration and management (n = 21, 15.00%), or education (n = 4, 2.85%). Benefits reported were primarily potential as most studies trained and tested AI algorithms. Only a handful (n = 8, 7.14%) reported actual benefits when AI techniques were applied in real-world settings. Risks and limitations included poor quality datasets that could introduce bias, the need for clinical interpretation of AI-based results, privacy and trust issues, and inadequate AI expertise among the professions. CONCLUSION: Digital health datasets should be put in place to support the testing, use, and evaluation of AI in nursing and midwifery. Curricula need to be developed to educate the professions about AI, so they can lead and participate in these digital initiatives in healthcare. RELEVANCE FOR CLINICAL PRACTICE: Adult, paediatric, mental health and learning disability nurses, along with midwives should have a more active role in rigorous, interdisciplinary research evaluating AI-based technologies in professional practice to determine their clinical efficacy as well as their ethical, legal and social implications in healthcare.

Waste-Wood-Isolated Cellulose-Based Activated Carbon Paper Electrodes with Graphene Nanoplatelets for Flexible Supercapacitors.

Waste wood, which has a large amount of cellulose fibers, should be transformed into useful materials for addressing environmental and resource problems. Thus, this study analyzed the application of waste wood as supercapacitor electrode material. First, cellulose fibers were extracted from waste wood and mixed with different contents of graphene nanoplatelets (GnPs) in water. Using a facile filtration method, cellulose papers with GnPs were prepared and converted into carbon papers through carbonization and then to porous activated carbon papers containing GnPs (ACP-GnP) through chemical activation processes. For the morphology of ACP-GnP, activated carbon fibers with abundant pores were formed. The increase in the amount of GnPs attached to the fiber surfaces decreased the number of pores. The Brunauer-Emmett-Teller surface areas and specific capacitance of the ACP-GnP electrodes decreased with an increase in the GnP content. However, the galvanostatic charge-discharge curves of ACPs with higher GnP contents gradually changed into triangular and linear shapes, which are associated with the capacitive performance. For example, ACP with 15 wt% GnP had a low mass transfer resistance and high charge delivery of ions, resulting in the specific capacitance value of 267 Fg-1 owing to micropore and mesopore formation during the activation of carbon paper.

Determinants of the intention to work in aged care: a cross-sectional study to assess gerontological nursing competencies among undergraduate nursing students.

BACKGROUND: There are huge demands for aged-care workers, and undergraduate gerontological nursing education plays a critical role in providing academic and professional training. PURPOSE: To examine relationships of characteristics, aged-care education, and gerontological nursing competencies with the intention to work in aged care. METHODS: An online survey was distributed to undergraduate nursing students between April and June 2022 to gather characteristics, relevant aged-care education, gerontological nursing competencies, and intentions to work in aged care data. Multivariate regression analyses were conducted to identify determinants of the intention to work in aged care. RESULTS: Students (n = 358) who were older (p < 0.001) and who were married (p < 0.001) had higher intentions to work in aged care. "Promoting mental health and psychological well-being", "Providing evidence-based dementia care", and "Enabling access to technology", were also associated with positive intentions. CONCLUSIONS: This study provides evidence on determinants of the intention to work in aged care, particularly gerontological nursing competencies.

Effectiveness of auricular acupoint therapy targeting menstrual pain for primary dysmenorrhea: A systematic review and meta-analysis of randomized controlled trials.

BACKGROUND: Primary dysmenorrhea (PD) is a global public health concern affecting women's health and quality of life, leading to productivity loss and increased medical expenses. As a non-pharmacological intervention, auricular acupoint therapy (AAT) has been increasingly applied to treat PD, but the overall effectiveness remains unclear. AIMS: The aim of this review was to synthesize the effects of AAT targeting menstrual pain among females with PD. METHODS: Eight databases (PubMed, EMBASE, AMED, CINAHL Plus, Cochrane Library, Web of Science, China National Knowledge Infrastructure and Wanfang Data) and three registries (ClinicalTrials.gov, ISRCTN Registry and the Chinese Clinical Trial Registry) were searched to identify existing randomized controlled trials (RCTs) from inception to 21 August 2022. Two reviewers independently screened, extracted the data, and appraised the methodological quality and the evidence strength using the Cochrane risk-of-bias tool for randomized trials (RoB 2) and the GRADE approach. RESULTS: A total of 793 participants from 11 RCTs were included. Despite substantial heterogeneity, AAT was more effective in reducing menstrual pain and related symptoms than placebo and nonsteroidal anti-inflammatory medications (NSAIDs). No significant subgroup differences were found between study locations as well as invasiveness, duration, type, acupoints number, ear selection and provider of AAT. Only minor adverse effects of AAT were reported. LINKING EVIDENCE TO ACTION: AAT can help women with PD, particularly those who are refrained from pharmaceuticals. Primary healthcare professionals, including nurses, can be well-equipped to provide evidence-based and effective AAT for people with PD. AAT can be used in a broader global clinical community. To provide an optimal effect and have wider usability, a unified practice standard is required, which would necessitate further adaptation of clinical care of people with PD. AAT effectively decreased menstrual pain and other accompanying symptoms of PD. More research is needed to identify effective AAT features and explore optimal therapy regimes for PD.

Dapagliflozin attenuates diabetes-induced diastolic dysfunction and cardiac fibrosis by regulating SGK1 signaling.

BACKGROUND: Recent studies have reported improved diastolic function in patients administered sodium-glucose cotransporter 2 inhibitors (SGLT2i). We aimed to investigate the effect of dapagliflozin on left ventricular (LV) diastolic function in a diabetic animal model and to determine the molecular and cellular mechanisms underlying its function. METHODS: A total of 30 male New Zealand white rabbits were randomized into control, diabetes, or diabetes+dapagliflozin groups (n = 10/per each group). Diabetes was induced by intravenous alloxan. Cardiac function was evaluated using echocardiography. Myocardial samples were obtained for histologic and molecular evaluation. For cellular evaluation, fibrosis-induced cardiomyoblast (H9C2) cells were obtained, and transfection was performed for mechanism analysis (serum and glucocorticoid-regulated kinase 1 (SGK1) signaling analysis). RESULTS: The diabetes+dapagliflozin group showed attenuation of diastolic dysfunction compared with the diabetes group. Dapagliflozin inhibited myocardial fibrosis via inhibition of SGK1 and epithelial sodium channel (ENaC) protein, which was observed both in myocardial tissue and H9C2 cells. In addition, dapagliflozin showed an anti-inflammatory effect and ameliorated mitochondrial disruption. Inhibition of SGK1 expression by siRNA decreased and ENaC and Na+/H+ exchanger isoform 1 (NHE1) expression was confirmed as significantly reduced as siSGK1 in the diabetes+dapagliflozin group. CONCLUSIONS: Dapagliflozin attenuated left ventricular diastolic dysfunction and cardiac fibrosis via regulation of SGK1 signaling. Dapagliflozin also reduced macrophages and inflammatory proteins and ameliorated mitochondrial disruption.

Effects of Mindfulness Yoga Versus Conventional Physical Exercises on Symptom Experiences and Health-related Quality of Life in People with Parkinson's Disease: The Potential Mediating Roles of Anxiety and Depression.

BACKGROUND: Although several studies have reported positive effects of mind-body exercises on symptom management and health-related quality of life (HRQOL) of people living with Parkinson's disease (PD), it is not known whether these effects are attributable to a change in anxiety and depression. PURPOSE: To compare the effects of mindfulness yoga to conventional stretching exercises in a randomized controlled trial while examining potentially mediating effects of anxiety and depression. METHODS: 138 adults with PD were randomized to eight weekly yoga (n = 71) or stretching (n = 67) sessions. Symptom experiences, anxiety and depression, and HRQOL outcomes were assessed at baseline, immediate post-intervention, and 3-month post-intervention. RESULTS: Generalized estimating equation analyses revealed that, compared to stretching, yoga significantly improved patients' nonmotor (time-by-group interaction, T1:ß = -1.99, p = .008; T2:ß = -2.86, p < .001) and motor (time-by-group interaction, T1:ß = -1.77, p = .03) symptom experiences. The mediation analysis found that the changes in anxiety and depression were the mediators in the associations between non-motor experience and HRQOL; while only the changes in depression were found to be the mediator in the relationship between motor experience and HRQOL. CONCLUSIONS: Yoga is superior to conventional stretching exercises in improving nonmotor and motor symptoms in daily living. Reduced anxiety and depression play a role in mediating the positive effects of the mindfulness yoga intervention. To optimize HRQOL, rehabilitation should reinforce psychological care in addition to pharmacological treatments and physical relief of PD symptoms. Future studies are needed to identify strategies for facilitating the implementation and sustainability of mind-body rehabilitation to enhance the quality of care for PD.

Mood disorders increase mortality mainly through dementia: A community-based prospective cohort study.

OBJECTIVE: The effects of mood disorders on mortality may be mediated by their effects on the risk of dementia, and interventions to reduce the occurrence of dementia may reduce their overall mortality. This study aimed to investigate the direct effects of depressive and bipolar disorders on the 6-year risk of mortality and also their indirect effects on mortality due to their effect on the risk of dementia. METHODS: A total of 5101 Koreans were selected from a community-based prospective cohort study, and 6-year risks of mortality and dementia in participants with depressive and bipolar disorders were estimated by Cox proportional hazard analysis. The direct and indirect effects of depressive and bipolar disorders on the risk of mortality were estimated using structural equation modeling. RESULTS: The depressive and bipolar disorder groups showed 51% and 85% higher 6-year mortality, and 82% and 127% higher risk of dementia, respectively, compared to euthymic controls. The effects of depressive and bipolar disorders on mortality were mainly mediated by their effects on the risk of dementia in a structural equation model. The direct effects of each mood disorder on mortality were not significant. CONCLUSION: Both depressive and bipolar disorders increased the risks of mortality and dementia, and the effects of mood disorders on mortality were mainly mediated through dementia. As dementia occurs later in life than mood disorders, measures to prevent it may effectively reduce mortality in individuals with a history of mood disorders, as well as being more feasible than attempting to control other causes of death.
