A comprehensive examination of temporal-seasonal variations of PM1.0 and PM2.5 in taiwan before and during the COVID-19 lockdown.

COVID-19 has been a significant global concern due to its contagious nature. In May 2021, Taiwan experienced a severe outbreak, leading the government to enforce strict Pandemic Alert Level 3 restrictions in order to curtail its spread. Although previous studies in Taiwan have examined the effects of these measures on air quality, further research is required to compare different time periods and assess the health implications of reducing particulate matter during the Level 3 lockdown. Herein, we analyzed the mass concentrations, chemical compositions, seasonal variations, sources, and potential health risks of PM1.0 and PM2.5 in Central Taiwan before and during the Level 3 lockdown. As a result, coal-fired boilers (47%) and traffic emissions (53%) were identified as the predominant sources of polycyclic aromatic hydrocarbons (PAHs) in PM1.0, while in PM2.5, the dominant sources of PAHs were coal-fired boilers (28%), traffic emissions (50%), and iron and steel sinter plants (22.1%). Before the pandemic, a greater value of 20.9 ± 6.92 µg/m3 was observed for PM2.5, which decreased to 15.3 ± 2.51 µg/m3 during the pandemic due to a reduction in industrial and anthropogenic emissions. Additionally, prior to the pandemic, PM1.0 had a contribution rate of 79% to PM2.5, which changed to 89% during the pandemic. Similarly, BaPeq values in PM2.5 exhibited a comparable trend, with PM1.0 contributing 86% and 65% respectively. In both periods, the OC/EC ratios for PM1.0 and PM2.5 were above 2, due to secondary organic compounds. The incremental lifetime cancer risk (ILCR) of PAHs in PM2.5 decreased by 4.03 × 10-5 during the pandemic, with PM1.0 contributing 73% due to reduced anthropogenic activities.

Depressive symptoms and daily living dependence in older adults with type 2 diabetes mellitus: the mediating role of positive and negative perceived stress.

BACKGROUND: Higher stress is associated with higher levels of depression and instrumental-activities-of-daily-living (IADL) dependence, and depression is strongly associated with specific IADL disabilities. Accordingly, the aim of this study was to investigate the mediating effect of perceived stress on the association between depression and IADL dependence among older adults with diabetes mellitus (DM). METHODS: We examined baseline data collected from a longitudinal study that recruited 110 patients with DM aged ≥ 65 years from the endocrinology outpatient clinic of a district hospital. The instruments used for our measurement processes comprised a demographic data sheet and Chinese versions of the Perceived Stress Scale (PSS), the short form of the Geriatric Depression Scale (GDS-S), and the Lawton IADL Scale. We assessed the mediating effects of positive perceived stress (PPS) and negative perceived stress (NPS) after controlling for five covariates by using a regression-based model run through the SPSS macro PROCESS. RESULTS: We observed negative correlations between GDS-S scores and PPS and between PPS and IADL dependence; we noted positive correlations between GDS-S scores and NPS and between NPS and IADL dependence (all P < 0.01). The indirect effect is coefficient = 0.12, [95% confidence interval = (0.0, 0.33)], suggesting that PPS achieves a mediating effect between depressive symptoms and IADL dependence. However, the NPS does not achieve a mediating effect in the relationship between depressive symptoms and IADL dependence (coefficient = 0.06, 95% CI = - 0.03, 0.15). CONCLUSIONS: Personal PPS mediates the association between depression and IADL dependence in older adults with DM. This finding suggests that providing patients with psychological education to promote their PPS may help prevent their functional decline.

The enrichment process for family caregivers of persons living with dementia: A grounded theory approach.

AIM: Many persons living with dementia (PLWD) reside in the community and are cared for by family members. The aim of this qualitative study was to gain an understanding the enrichment process for family caregivers of PLWD in Taiwan. DESIGN: A grounded theory approach with face-to-face semi-structured interviews was conducted with family caregivers of PLWD in Taiwan. METHODS: Interview data from 30 family caregivers of PLWD recruited from dementia clinics or support groups in Taiwan were obtained from the first wave of a larger study conducted from January 2018 to September 2021. Glaser's grounded theory approach with theoretical sampling was used to understand the enrichment process of family caregivers of PLWD. RESULTS: Analysis indicated the core category that characterized the process of enrichment was 'holding together'. Caregivers were able to maintain their connection to the person with dementia through activities that deepened their relationship and strengthened their bond. 'Holding together' included four components: maintaining continuity, creative interactions, interacting with humour and sharing pleasurable activities. Through these components, family caregivers generated positive interactions and relationships with the person living with dementia and sustained their motivation for caregiving. Three modifying elements facilitated or impeded the process of holding together: 'previous daily interactions', 'caregiving beliefs' and 'filial piety'. CONCLUSION: Through the enrichment process of 'holding together', family caregivers used different strategies to conduct pleasurable and meaningful activities with the person living with dementia to maintain and improve their relationship and enhance their happiness in life. IMPACT: To facilitate the enrichment process, health care providers should encourage activities between family caregivers and PLWD that promote continuity, increase interactions, provide humour and foster pleasurable activities. REPORTING METHOD: This study adhered to the COREQ guideline checklist. PATIENT OR PUBLIC CONTRIBUTION: No patient or public contribution.

Relation of environmental factors with activity limitations and participation restrictions in older adults with diabetes mellitus over time: an international classification of functioning framework perspective.

BACKGROUND: Activity limitations and participation restrictions were observed in patients with diabetes, which may impact their quality of life. Environmental factors such as seasonal effects, resources and perceived stress may play important role in activity limitations and participation restrictions. In this study, a variant of International Classification of Functioning (ICF) model was used to clarify the associations of function/structure factors, personal factors and environmental factors with activity limitations and participation restrictions. METHODS: This was a longitudinal design with 1 year follow-up. The Mini-Mental State Examination (MMSE), Geriatric Depression Scale- short form, Perceived Stress Scale, and Instrumental Activities of Daily Living assessments were measured at 3-month intervals for long-term follow-up in 110 patients with diabetes aged ≥ 65 years. RESULTS: Hierarchical linear regression models revealed that age (p = 0.001), perceived health status, MMSE scores (p < 0.01), and positive perceived stress (p < 0.001) were predictors of activity limitations (adjusted R2 = 53%). GDS-S (p < 0.05) and positive perceived stress (p < 0.01) were predictors of participation restrictions (adjusted R2 = 30%). Generalized estimating equation analysis indicated that seasonal effects, age, perceived health status, MMSE predicted the changes of slopes in activity limitations. Seasonal effects and GDS-S were predictors of the changes of slopes for participation restrictions (all p < 0.001). CONCLUSIONS: The ICF can be used to identify the risk factors for activity limitations and participation restrictions in older adults with diabetes. Practitioners should provide individualized interventions with consideration of these risk factors.

[Effects of Multicomponent Case Management on the Problem Behaviors of Patients With Dementia and Family Caregivers' Distress, Self-Efficacy, Depression, Burden and Health Promotion Behaviors].

BACKGROUND: Few of the interventions currently available for family caregivers (FCGs) of persons with dementia (PWDs) with long-term follow-ups have a grounding in theory and incorporate multicomponent case management formats. PURPOSE: Based on Pearlin's Caregiving and Stress Process model, this study was developed to examine the effectiveness of a family-centered case management program for PWDs with early to moderate dementia in terms of reducing PWDs behavioral problems and improve FCG outcomes, including distress, self-efficacy, depression, caregiver burden, and health-promoting behaviors. METHODS: This randomized, single-blind, parallel-controlled trial included 76 dyads of PWDs and their FCGs. The dyads were recruited from outpatient clinics at dementia centers in three district hospitals in northern Taiwan. The dyads were randomly assigned to the intervention group (IG, n = 39) and control group (CG, n = 37). The dyads in the IG received a four-month intervention with two home or clinic visits and two telephone interviews. The multi-component interventions provided assessment, education, consultations, support, and referrals to long-term care resources. The CG received routine care and two social phone calls. Data were collected upon enrollment (T0 = baseline) and at 4-,6-, and 12-months post-intervention (T1, T2, and T3, respectively). Generalized estimating equations were conducted to analyze the effects of the intervention. RESULTS: By controlling for the interaction between group and time, we made a comparison between IG and the CG. The results showed significant improvements from baseline measures in behavioral problems in the PWDs for mood, psychosis, and social engagement, and improvements in the FCGs for distress and self-efficacy for obtaining respite as well as for better control of distressing thoughts, feelings of depression, caregiver burden, and overall health promoting behaviors at T1 and T2 (p < 0.5). Significant improvements were also found in the IG for psychomotor regulation among PWDs and the self-efficacy of FCGs in managing the PWDs' disturbing behaviors and health promotion behaviors for nutrition at T1 (p < 0.5). There were no significant improvements in the outcome variables at T3. CONCLUSIONS / IMPLICATIONS FOR PRACTICE: Significant interactions between group and time were found at the 6-month assessment (T2) for improvements in problem behaviors of PWDs and depression, caregiver burden, and distress in the FCGs. Positive effects on self-efficacy and health promotion behaviors among the FCGs were also achieved. The results suggest that a multicomponent case management intervention should be referenced in dementia care policymaking for FCGs and PWDs.

Traumatic testicular dislocation: A case report and literature review.

INTRODUCTION: Traumatic testicular dislocation is an uncommon complication of blunt scrotal injury and is easily overlooked because of the presence of other severe accompanying injuries. In most cases, an operation is needed for the prevention of malignant change or infertility. PATIENT CONCERNS AND DIAGNOSIS: We report a case of traumatic testicular dislocation with pelvic fracture and internal bleeding in a 27-year-old male with testis rupture after a motorcycle collision. INTERVENTIONS AND OUTCOMES: He received emergent right radical orchiectomy, and a series of operations for femoral and pelvic fractures were performed after his condition stabilized in the intensive care unit. After 1 month postsurgery, no obvious genitourinary complications were noted. CONCLUSION: We suggest scrotum examination in all trauma patients, particularly if a pelvic injury is suspected or in case of a high risk of a motorcycle collision, to avoid missing the diagnosis and prevent severe complications.

The Mediating Effect of Spiritual Well-Being and Quality of Life for Persons with Parkinson's Disease in Northern Taiwan.

BACKGROUND: Parkinson's disease (PD), a degenerative disease with irreversible motor dysfunction, impacts patients' quality of life (QoL). Spirituality can provide a sense of hope and meaning when individuals are faced with adverse life events, such as a diagnosis of PD. However, few studies have examined the relationship between spiritual well-being and QoL for persons with PD. OBJECTIVE: To explore the relationships between the disease characteristics, spirituality and QoL for persons with PD, and verify the mediating effects of spirituality on the relationship. METHODS: This cross-sectional study recruited patients with PD (n = 110) by convenience sampling from a neurological clinic in northern Taiwan. Variables were measured using the Spirituality Index of Well-Being Chinese version (SIWB-C) and the 39-item Parkinson's disease Quality of Life Questionnaire Chinese version (PDQ-39-C) self-report questionnaires. Descriptive analysis and linear hierarchical regression were conducted to examine the studied variables and explore the mediating effect of spiritual wellbeing. RESULTS: Those whose scores were significantly better in PDQ-39 were younger, employed, with shorter disease duration and less severe condition with better functioning on their early stages and lower LEDD; additionally, those who had better quality of life also experienced better spiritual wellbeing than the counterparts. The regression model demonstrated spiritual self-efficacy had mediating effects between disease characteristics and QoL, explaining 69.8%of the variance (adjusted R2 = 65.3%). CONCLUSION: The results can be the references for future strategies and interventions, focusing on increasing spiritual self-efficacy and reducing the impact of disease severity to improve QoL for persons with PD.

Perceptions of community dementia friendliness: A cross-sectional study of people with dementia, family caregivers, service providers, and the general public in Taiwan.

Promoting dementia-friendly communities is an important strategy for improving quality of life for people with dementia and dementia-family caregivers. The process of building dementia-friendly communities should include all people living in the community. The objective of this study was to compare perceived dementia friendliness in the community among people with dementia, family caregivers, service providers, and the general public. In Taiwan, we surveyed 60 people with dementia, 140 family caregivers, and 200 members of the general public face to face, with 200 service providers surveyed by mail. Participants completed the Perceived Community Dementia Friendliness measure, consisting of seven subscales: care services, community members, community environment, community interactions, transportation, hospitals, and stores and organisations. This measure has acceptable convergent validity, construct validity, and internal consistency reliability for use in Taiwan. Differences in perceived dementia friendliness were examined by chi-square tests/analysis of variance. Among the seven subscales, hospitals were rated with good dementia friendliness by 70% of people with dementia (n = 42); however, care services were rated poor by 23.3% of people with dementia (n = 14). Hospitals were also rated with good dementia friendliness by 39.2% of family caregivers (n = 54). Care services were rated as having good dementia friendliness by 43.5% of service providers (n = 87) and 47% of the general public (n = 86). Furthermore, community interactions were rated as good by small percentages of family caregivers (11.4%, n = 16), service providers (22.2%, n = 44), and the general public (30.9%, n = 58). Family caregivers, service providers, and the general public rated hospitals with the highest mean dementia-friendliness score and community interactions with the lowest. Perceived community-dementia friendliness among participants with dementia differed from that of participants without. People with dementia prioritised improving care services, while people without dementia rated facilitating community interactions as more vital. These differences provide vital insights into understanding the policies and administration of dementia-friendly communities.

Investigation of the molecular mechanism underlying the inhibitory activities of ethanol extract of Bombyx mori pupa-incubated Cordyceps militaris fruiting bodies toward allergic rhinitis.

Cordyceps militaris has been widely studied for its various pharmacological activities such as antitumor, anti-inflammation, and immune regulation. The binding of an allergen to IgE-sensitized mast cells in nasal mucosa triggers allergic rhinitis. We found that oral administration of 300 mg/kg of the ethanol extract prepared from silkworm pupa-cultivated Cordyceps militaris fruiting bodies significantly alleviated the symptoms of ovalbumin-induced allergic rhinitis in mice, including sneeze/scratch, mast cell activation, eosinophil infiltration, and Syk activation. The treatment of ethanol extract significantly suppressed the release of ß-hexosaminidase (a degranulation marker) and mRNA expression levels of various cytokines, including IL-3, IL-10, and IL-13 in activated RBL2H3 cells. The ethanol extract and ß-sitostenone, which was purified from the extract, could respectively reduce the Ca2+ ion mobilization in activated RBL-2H3 cells. Furthermore, results collected from western immunoblotting demonstrated that ethanol extract significantly retarded Ca2+ ion mobilization-initiated signaling cascade, which provoked the expression of various allergic cytokines. Also, the extract incubation interfered with P38 as well as NF-kB activation and Nrf-2 translocation. Our study suggested that ethanol extract possessed some natural constituents which could inhibit immediate degranulation and de novo synthesis of allergic cytokines via inhibition of Ca2+ ion mobilization in mast cells in the nasal mucosa of allergic rhinitis mice.

Can We Use Grip Strength to Predict Other Types of Hand Exertions? An Example of Manufacturing Industry Workers.

BACKGROUND: There are different types of hand motions in people's daily lives and working environments. However, testing duration increases as the types of hand motions increase to build a normative database. Long testing duration decreases the motivation of study participants. The purpose of this study is to propose models to predict pinch and press strength using grip strength. METHODS: One hundred ninety-eight healthy volunteers were recruited from the manufacturing industries in Central Taiwan. The five types of hand motions were grip, lateral pinch, palmar pinch, thumb press, and ball of thumb press. Stepwise multiple linear regression was used to explore the relationship between force type, gender, height, weight, age, and muscle strength. RESULTS: The prediction models developed according to the variable of the strength of the opposite hand are good for explaining variance (76.9-93.1%). Gender is the key demographic variable in the predicting models. Grip strength is not a good predictor of palmar pinch (adjusted-R2: 0.572-0.609), nor of thumb press and ball of thumb (adjusted-R2: 0.279-0.443). CONCLUSIONS: We recommend measuring the palmar pinch and ball of thumb strength and using them to predict the other two hand motions for convenience and time saving.

Experiences of Living in the Community for Older Aboriginal Persons With Dementia Symptoms in Taiwan.

BACKGROUND AND OBJECTIVES: Improving quality of life for community-dwelling older persons with dementia symptoms (PWDS) and family caregivers requires promoting dementia-friendly communities (DFC). However, little is known regarding older Taiwanese Aboriginal PWDS' experiences of living in the community. We explored these experiences for older Atayal PWDS and their families in Taiwan. RESEARCH DESIGN AND METHODS: This grounded theory research used in-depth interviews to explore the perspectives of older PWDS (n = 4), their family members (n = 3), and key persons (n = 10) in an Atayal community in northern Taiwan. Data were analyzed using constant comparative analysis. Participants were interviewed between January and May 2015. RESULTS: Participants' experiences were captured by the overarching concept of "low dementia awareness, high family-like ambience in the community." Despite the low/absent community awareness of dementia, older Atayal PWDS functioned as freely in the community as at home due to a family-like supportive environment. Aboriginal PWDS and their families also faced environmental challenges, e.g., environmental constraints and barriers to transportation access. DISCUSSION AND IMPLICATIONS: Our results suggest that this Aboriginal community and culture offer important DFC components, and these strengths could be further studied to enhance DFC models elsewhere. Despite these strengths in supporting PWDS, environmental challenges to transportation access still cause difficulties for PWDS and their families and need improvement. The Atayal community's low dementia awareness suggests that services introduced must be culturally appropriate and nondisruptive to existing supportive helping systems. Our study can be a model for future studies to understand and identify PWDS' needs in Indigenous communities.

The mediating effects of leisure engagement on relationships between caregiving stress and subjective wellbeing among family caregivers of persons with cognitive impairment: A cross-sectional study.

Family caregivers of persons with cognitive impairment experience changes in reductions in leisure engagement, which can decrease their subjective wellbeing (leisure satisfaction, negative affect and positive affect). We recruited 100 dyads of patients with cognitive impairment and family caregivers by convenience sampling from outpatient memory clinics and daycare centers in northern Taiwan. Hierarchical regression analysis tested the mediating effects of leisure engagement on the relationship between caregiving stress and subjective wellbeing. Results indicated that the restorative experience of event/tourism activities (ß = 0.23, p < .05) significantly mediated between caregiving stress and leisure satisfaction. In addition, the only significant mediator between caregiving stress and negative affect was leisure barriers (ß = 0.21, p < .05). Both of the regression models explained 27% of the variance. Future development of leisure interventions should focus on reducing leisure barriers and providing event and tourism activities to the dyads. (146 words).

A Pilot Study of Five Types of Maximum Hand Strength among Manufacturing Industry Workers in Taiwan.

Background: The purpose of this study is to collect five types of maximum hand strength among workers in the manufacturing industry in Taiwan. Methods: This study is a cross sectional study with a stratified and convenient sample of workers on the production line in manufacturing industries in Central Taiwan. In total, we recruited 198 healthy subjects to participate in this study. Five types of hand strength were measured in both hands three times with 3 min rests between trials. Results: The strength of females for these five types of hand exertions were 52.0% to 67.6% of the strength of males (p < 0.001). For both genders, there was a main effect for the types of hand strength for the right hand (p < 0.001) and the left hand (p < 0.001). In general, the hand strength in U.S. and EU countries was 1.2 to 1.7 times greater than the strength among the three types of hand exertions in this study. Conclusion: These results can be used to evaluate the musculoskeletal burdens on the upper extremities in the manufacturing industry and could also be used for tool and job design and job modifications.

Dementia-friendly community indicators from the perspectives of people living with dementia and dementia-family caregivers.

AIMS: To identify dementia-friendly communities' indicators and their current conditions in Taiwan from the perspectives of people with dementia and dementia-family caregivers. DESIGN: This qualitative study explored the opinions and experiences of people with dementia and dementia-family caregivers regarding dementia-friendly communities. METHODS: Participants (16 people with dementia and 20 family caregivers) were recruited from neurological clinics, day care centres for people with dementia and support groups for family caregivers in the Taipei community from July - October, 2016. Data were collected in face-to-face interviews, which were tape recorded and transcribed verbatim. Transcripts were analysed by Miles and Huberman's (1994) guidelines. RESULTS: Similar indicators for dementia-friendly communities were identified in Taiwan as in other countries, including dementia-friendly care services, dementia-friendly hospitals, dementia-friendly community environment, dementia-friendly transportation, dementia-friendly stores and shops, dementia friendly people, integrated dementia-related information and community contribution- and -involvement opportunities for people with dementia. However, Taiwanese people with dementia and family caregivers described no emphasis on the potential of people with dementia to contribute to developing dementia-friendly communities and more top-down expectations for the government's role. CONCLUSION: These indicators can be a guide for developing and evaluating dementia-friendly communities in Taiwan. Differences between Taiwan and Western developed countries in indicators for dementia-friendly communities can be further explored. Community nursing assessment, interventions, and evaluation based on these dementia-friendly communities indicators can be further developed. IMPACT: This study developed indicators for dementia-friendly communities in an Asian country. These indicators can be used as a guide for developing and evaluating dementia-friendly communities.

Caregiving demands, job demands, and health outcomes for employed family caregivers of older adults with dementia: Structural equation modeling.

Many family caregivers are also employed full- or part-time and are known to be affected by job demands. This study explored the mediating effect of job demands on the relationship between caregiving demands and caregiver health outcomes in primary family caregivers of older persons with dementia in Taiwan (N = 214). A cross-sectional design using a self-completed structured questionnaire was implemented. Structural equation modeling analyses showed that job demands partially mediated the relationship between caregiving demands and caregiver health outcomes. The indirect effect of caregiving demands on caregiver health outcomes through job demands was 0.208 (95% confidence interval: 0.053 - 0.335). Nurses should evaluate job demands when screening for high-risk caregiver groups vulnerable to high caregiving demand. Interventions aimed at lessening both caregiving demands and job demands may improve caregiver health outcomes for family caregivers of older adults with dementia.

Protective preparation: a process central to family caregivers of persons with mild cognitive impairment.

ABSTRACTBackground:To develop a theoretical model explaining the longitudinal changes in the caregiving process for family caregivers of persons with mild cognitive impairment (MCI) in Taiwan. METHODS: A longitudinal, grounded theory approach using in-depth face-to-face interviews and an open-ended interview guide. We conducted 42 interviews over a two-year period; each participant was interviewed at least once every six months. All participants were interviewed in their home. The participants total of 13 family caregivers of persons with MCI. RESULTS: One core theme emerged: "protective preparation." This reflected the family caregiving process of preparation for a further decline in cognitive function, and protection from the impact of low self-esteem, accidents, and symptoms of comorbidities for the family member with MCI. Protective preparation contained three components: ambivalent normalization, vigilant preparation, and protective management. CONCLUSIONS: Interventions to help family caregivers manage the changes in persons with MCI can reduce caregiver burden. Our findings could provide a knowledge base for use by healthcare providers to develop and implement strategies to reduce caregiver burden for family caregivers of persons with MCI.

Risky wandering behaviors of persons with dementia predict family caregivers' health outcomes.

OBJECTIVES: To examine the relationships between dementia persons' risky wandering behaviors and family caregivers' physical and mental health. METHODS: A secondary analysis was conducted using the original cross-sectional data from180 dyads. The Risky Wandering and Adverse Outcome model assessed behaviors of eloping and getting lost outside the house for dementia persons. Data were analyzed using descriptive statistics, Pearson's correlation coefficient and hierarchical regressions. RESULTS: The mean age of caregivers was 56.01 years (SD = 13.8); 65% were female. Younger caregivers experienced greater physical fatigue and sleep disturbance. Presence of foreign helpers predicted a reduction in mental and physical fatigue of caregiver (ß = -0.186, p < .05; ß = 0.198, p < .05, respectively). Getting lost outside of the house influenced caregivers' mental fatigue (ß = 0-0.215, p < .05); eloping behavior influenced caregivers' sleep disturbance (ß = 0.231, p < .05). Care-receivers' activities of daily living affected caregivers' depressive symptoms (ß = -0.179, p < .05). CONCLUSIONS: Dementia family caregiver physical and mental health problems have distinct predictors. Employing the Risky Wandering and Adverse Outcome model could inform policy makers regarding long-term care resources to improve dementia care.

[Reducing the Care-Related Burdens of a Family Caregiver of a Person With Mild Cognitive Impairment: A Home-Based Case Management Program].

The long-term care of cognitively impaired patients with concomitant behavioral problems brings great stress and burdens to family caregivers. The present article describes a family caregiver with multiple chronic diseases who concurrently shouldered primary care responsibilities for her husband, a patient with mild cognitive impairment, problematic behaviors, and medication non-adherence issues. The period of care was between September 23rd and December 29th, 2015. Data on physiological, psychological, and social burdens were collected based on a stress process model for family caregiving. We then applied a home-based, individually tailored intervention, which included nursing education, skills training, listening/counseling, and resource connecting, that effectively helped the family caregiver reduce her burdens. Our assessment identified nursing-care-related problems as the primary source of caregiver burden in this case, with identified stressors including a lack of knowledge regarding patient care, medication management problems, sleep disorders, and inadequate social resources. Using continuous care interactions, we established a trust relationship with the family caregiver, prioritized her needs, and provided dementia care knowledge and skills, which gradually improved her caregiving competence. Our instruction included increasing caregiver understanding of the disease course of dementia, related problematic behaviors, and medication management. Our intervention enhanced the disease awareness of the caregiver and helped her become more positive about her caregiving tasks. Therefore, the negative impacts on her family were reduced. Social support and long-term care resources further reduced her burden and improved her quality of life.

The co-occurrence of depressive symptoms and cognitive impairment and its relationship with self-care behaviors among community dwelling older adults with diabetes.

AIMS: The aims of the present study were to investigate the co-occurrence of depressive symptoms and cognitive impairment in community dwelling older adults with diabetes and its relationship with specific diabetes self-care behaviors. METHODS: We analyzed data from two national samples of older adults (65years or older) with self-reported physician-diagnosed diabetes (N=1034), who participated in the 2005 or 2009 National Health Interview Survey in Taiwan. The Mini-Mental State Examination was used to assess cognitive function. The Center for Epidemiologic Studies Depression Scale was used to assess depressive symptoms. The study assessed self-care behaviors including medication adherence, exercise, healthy diet, and self-monitoring of blood glucose. RESULTS: In this study, 8.8% of participants with diabetes had both depressive symptoms and cognitive impairment. After adjusting for other factors, participants with both cognitive impairment and depressive symptoms were less likely to exercise (Prevalence Ratios (PR)=0.66; 95% Confidence Intervals (CI)=[0.47-0.91]; P-value=0.011), and have a healthy diet (PR=0.82; 95%CI=[0.70-0.96]; P-value=0.012). CONCLUSIONS: Our results illustrate the high prevalence of combined depressive symptoms and cognitive impairment and that this combination is associated with worse self-care behaviors in older adults with diabetes. These findings highlight the difficulty that some older adults with diabetes may have in maintaining self-care behaviors in the presence of depressed mood and cognitive impairment, particularly in the areas of diet and exercise. The results emphasize the importance of providing more support for these aspects of self-care to such older adults.

Predictors of self- and caregiver-rated quality of life for people with dementia living in the community and in nursing homes in northern Taiwan.

BACKGROUND: Factors affecting quality of life (QOL) ratings for people with dementia (PWD) have been well studied, but few studies have examined the effect of residence on PWD- and caregiver-rated QOL for PWDs. We designed this study to determine the factors related to PWD- and caregiver-rated QOL in dementia as well as factors related to the discrepancy in these ratings. METHODS: For this cross-sectional study, we analyzed data from a convenience sample of 106 PWD-family caregiver dyads (58 community-dwelling dyads and 48 nursing-home dyads). PWDs' data included socio-demographic variables, QOL (assessed by the Quality of Life-Alzheimer's Disease [QOL-AD] scale), cognition, dementia severity, depression, comorbidities, and quality of the dyadic relationship. Caregivers' data included socio-demographic variables, depressive symptoms, and mutuality of the dyadic relationship. RESULTS: QOL-AD scores were lower when rated by caregivers than by PWDs. The key factors positively related to both PWD- and caregiver-rated QOL for PWDs were fewer PWD depressive symptoms and higher quality of the PWD-caregiver relationship. The key factors related to the discrepancy in PWD- and caregiver-rated QOL in dementia were PWD residence in a nursing home and lower dementia severity, as well as higher caregiver depression, being an adult child caregiver, and lower caregiver-PWD mutuality. CONCLUSION: Caregiver-rated QOL for PWDs and the discrepancy in rated QOL were significantly associated with PWD residence. If caregiver-rated QOL is needed, the effect of residence of PWD should be taken into consideration. Caregivers' depressive status and mutuality with PWD must be also carefully assessed.
