Work and self-rated memory among native Hawaiian and other Pacific Islander older adults.

OBJECTIVES: Engagement in work has an important association with cognitive health in later life, yet little is known about this association among Native Hawaiian and other Pacific Islander (NHPI) older adults. This study assesses the associations between various work characteristics and memory problems among this population. DESIGN: Using data from the 2014 Native Hawaiian and Pacific Islander National Health Interview Survey (NHPI NHIS), the research question was explored among those who were aged 50+. RESULTS: Engagement in work, certain occupation types (e.g., clerical or professional occupations compared to blue-collar jobs), and the current/most recent job that is also the longest job held were associated with lower odds of having memory problems. CONCLUSION: The study's results suggest that work characteristics and opportunities to engage in work are important considerations in preventing memory problems in later life. As the NHPI population experiences cognitive health disparities earlier than other groups, timely interventions that focus on work engagement and a culturally relevant environment require further investigation.

Attention-Deficit Hyperactivity Disorder among children of immigrants: immigrant generation and family poverty.

OBJECTIVES: Attention-Deficit Hyperactivity Disorder (ADHD) is one of the most common disorders diagnosed among children in the US. However, little knowledge is available about ADHD prevalence among children of immigrants, the fastest-growing population in the US. This study seeks to examine ADHD rates among children of immigrants in different generations compared to children of US-born parents and their association with family poverty. DESIGN: The sample includes 83,362 children aged 0-17 from the National Health Interview Survey (NHIS) 2010-2018 data. Multivariate logistic regression model is used to estimate prevalence of ADHD among children of immigrants compared to children of US-born parents. We then compare ADHD rates among the children sample in different immigrant generations. For all analyses, we examine ADHD occurrence separately for children in families living below the poverty threshold and those at or above the poverty threshold. RESULTS: The odds of having ADHD were significantly lower among children of immigrants compared to children of US-born parents. Both first-generation children and second-generation children of immigrants had significantly lower odds of having ADHD than children of US-born parents. Post hoc tests find that first-generation children had lower odds of having ADHD compared to second-generation children. Likewise, additional analyses showed that children of immigrants, first-generation children in particular, were less likely to have ADHD compared to children of US-born parents, in both lower- and higher-income families. CONCLUSION: Using a nationally representative sample of children, we find that the likelihood of having ADHD increases with higher generations, detecting differences in ADHD prevalence by immigration generation. Importantly, first-generation children had a significantly lower risk of having ADHD conditions compared to second-generation children and children of US-born parents, regardless of family socio-economic status. Public health policy and program development would gain from a clear comprehension of the shielding attributes of ADHD among immigrant families.

Care Workers' Turnover Intentions Associated With Workplace Abuse: The Role of Work-Related Stress and Job Satisfaction.

This study examines the association between workplace abuse experienced by care workers at the hands of care recipients and their turnover intentions, as well as the mediating effects of work-related stress and job satisfaction. Compared to care recipients' experiences of abuse, care workers' experiences have been relatively underexplored. Using data from the Korean National Long-Term Care Survey in 2019, the path from workplace abuse to care workers' turnover intentions was examined. Results showed significant mediating effects of work-related stress and job satisfaction in the relationship between workplace abuse and turnover intentions. Findings have policy implications for improving long-term care workers' social awareness and working conditions.

Inequities in access to directly-funded home care in Canada: a privilege only afforded to some.

BACKGROUND: Directly-funded home care (DF) provides government funds to people who need assistance with the activities of daily living, allowing them to arrange their own services. As programs expand globally, many allow DF clients to hire home care agencies to organize their services rather than finding their own workers. In Canada, half of the DF home care programs allow users to purchase agency services. The goal of this research is to describe the role of agency providers in DF home care in Canada and consider potential equity implications for service access from the perspectives of clients and families. METHODS: Framed with intersectionality, the study included online focus groups with families and clients (n = 56) in the two Canadian provinces of Alberta and Manitoba between June 2021-April 2022. All transcripts underwent qualitative thematic analysis using open and axial coding techniques. Each transcript was analyzed by two of three possible independent coders using Dedoose qualitative analysis software. RESULTS: The article presents five thematic findings. First, the focus groups document high rates of satisfaction with the care regardless of whether the client uses agency providers. Second, agency providers mediate some of the administrative barriers and emotional strain of using DF home care, and this is especially important for family caregivers who are working or have additional care responsibilities. Third, there are out-of-pocket expenses reported by most participants, with agency clients describing administrative fees despite lower pay for the frontline care workers. Fourth, agencies are not generally effective for linguistic and/or cultural matching between workers and families. Finally, we find that DF care programs cannot compensate for a limited informal support network. CONCLUSIONS: Clients and families often intentionally choose DF home care after negative experiences with other public service options, yet the results suggest that in some Canadian contexts, DF home care is a privilege only afforded to some. Given the growing inequalities that exist in Canadian society, all public home care options must be open to all who need it, irrespective of ability to pay, degree of social support, or competence in the English language.

Anti-Asian Racism and COVID-19 Impact on Older Adults: The Voices of Social Workers.

Heightened anti-Asian racism and hate crimes during the COVID-19 pandemic impacted older adults and the social workers who supported them. Yet, the experiences of Asian and Asian American (AAA) social workers are unknown. This study aimed to explore the perspectives and experiences of social workers focusing on the aging population during the anti-Asian racism climate and the COVID-19 pandemic. Guided by a qualitative approach, seventeen AAA social workers participated in semi-structured interviews. Based on thematic analysis, the following themes were identified: concerns about safety and discrimination, perceived service and support needs for older adults, and perceived generational gaps in advocacy. Social work practice, policy, and research implications are discussed.

Intersectionality, health equity, and EDI: What's the difference for health researchers?

Many countries adopted comprehensive national initiatives to promote equity in higher education with the goal of transforming the culture of research. Major health research funders are supporting this work through calls for projects that focus on equity, resulting in a proliferation of theoretical frameworks including "intersectionality," "health equity," and variations of equity, diversity and inclusion, or EDI. This commentary is geared at individual principal investigators and health research teams who are developing research proposals and want to consider equity issues in their research, perhaps for the first time. We present histories and definitions of three commonly used frameworks: intersectionality, health equity, and EDI. In the context of health research, intersectionality is a methodology (a combination of epistemology and techniques) that can identify the relationships among individual identities and systems of oppression; however, it should also be used internally by research teams to reflect on the production of knowledge. Health equity is a societal goal that operationalizes the social determinants of health to document and address health disparities at the population level. EDI initiatives measure and track progress within organizations or teams and are best suited to inform the infrastructure and human resourcing "behind the scenes" of a project. We encourage researchers to consider these definitions and strive to tangibly move health research towards equity both in the topics we study and in the ways we do research.

Mental Health of Employed Family Caregivers in Canada: A Gender-Based Analysis on the Role of Workplace Support.

This study examines the effect of gender differences in mental health outcomes among employed family caregivers, focusing on the role of workplace support in balancing work and caregiving. Guided by the social role theory, this study analyzes nationally representative data from the 2012 Canada General Social Survey, with a sample of 2,426 participants. Women experience worse mental health outcomes than men when they require employment adjustment to fulfill their caregiving responsibilities. Workplace support could offset the negative effects of employment adjustment on mental health either directly or indirectly through family-work conflict, but gender difference is apparent in terms of the effect of workplace support. In general, women require more supportive workplace than men. Further study of the effects of various types of workplace support on the mental health among women who are employed family caregivers, and on more tailored support, is recommended.

Developing a culturally responsive dementia storybook with Native Hawaiian youth.

Similar to the nation's majority and racial/ethnic minority populations, Native Hawaiian families provide the bulk of care to loved ones with dementia. Limited research has focused on youth caregivers, who are largely invisible to the eldercare service system. This knowledge gap is especially critical for Native Hawaiians who place a high value on eldercare, often provided in multigenerational homes. To address this gap, we describe the process by which a university-community center developed a culturally responsive storybook on dementia targeted to Native Hawaiian youth. The development process honored community-based participatory research principles grounded in the cultural values and practices of Native Hawaiians, active collaboration of an advisory council, and face-to-face engagement with Native Hawaiian youth. Future directions are shared about culture-based programming and evaluation in dementia care that may be useful in work with other racial/ethnic youth and families.

Neighborhood Social Cohesion and the Health of Native Hawaiian and Other Pacific Islander Older Adults.

Native Hawaiian and other Pacific Islander (NHPI) older adults experience various social and health challenges. There is a growing literature linking neighborhood conditions with health, yet few have focused on NHPI older adults. This study examines associations between neighborhood social cohesion and health outcomes (i.e., self-rated health, psychological distress, and memory) in this population. Data from the 2014 Native Hawaiian and Pacific Islander National Health Interview Survey (n=1,045 with respondents aged 50+) were analyzed with logistic regression models. The level of neighborhood social cohesion was determined by responses to items on perceptions of mutual help, dependability, trust, and close relationships within the neighborhood. Higher perceived neighborhood social cohesion was associated with lower odds of having serious psychological distress or memory problems. There was no statistical association of social cohesion with self-rated health. Socially cohesive neighborhoods are important to the health of NHPI. We discuss methods to improve neighborhood social cohesion as a way to promote health equity for NHPI older adults in the United States (U.S.).

Production of 7,10,12-trihydroxy-8(E)-octadecenoic acid from ricinoleic acid by Pseudomonas aeruginosa KNU-2B.

Microbial production of hydroxy fatty acids (HFAs) was widely studied because of important biological properties of HFAs. Among microorganisms producing HFAs, Pseudomonas aeruginosa PR3 was well known to produce various HFAs from different unsaturated fatty acids. Recently, a new variant species of P. aeruginosa PR3 was isolated and characterized, showing improved efficiency for producing 7,10-dihydroxy-8(E)-octadecenoic acid from oleic acid. In this study, we report the production of 7,10,12-trihydroxy-8(E)-octadecenoic acid (TOD) from ricinoleic acid by the newly isolated P. aeruginosa KNU-2B. TOD was efficiently produced from ricinoleic acid by KNU-2B with the maximum conversion yield of 56.7% under the optimum reaction conditions of pH 8.0 and 48-h incubation at 27 °C, 150 rpm. Under optimized reaction conditions, maximum TOD production reached 340.3 mg/100 mL of the culture. However, requirement of nutritional factors by KNU-2B for production of TOD were considerably different from those by PR3 strain.

Strong alkaline condition is preferable for producing 7,10-dihydroxy-8(E)-hexadecenoic acid from palmitoleic acid by Pseudomonas aeruginosa KNU-2B.

Microbial bioconversion of a given substrate is considered an efficient and eco-friendly tool for value-added industrial compound generation from natural products. Among natural products, unsaturated fatty acids have been used as substrates to produce various functional hydroxy fatty acids. In this study, we report the production of 7,10-dihydroxy-8(E)-hexadecenoic acid (DHD) from palmitoleic acid by a new strain, Pseudomonas aeruginosa KNU-2B. KNU-2B efficiently produced DHD from palmitoleic acid and required a strong alkaline condition for maximum DHD production. The maximum DHD amount produced under pH 10.0 and 48-h incubation at 27 °C and 150 rpm was 219.5 mg/100 mL culture. Other important nutritional factors were also investigated to obtain optimum DHD production.

Employment adjustment and mental health of employed family caregivers in Canada.

Family caregivers make employment adjustment to fulfill caregiving responsibility. However, the studies on the family caregivers' mental health outcomes associated with their employment adjustment are limited. This study utilized the role theory and stress process model of caregiving to examine the relationship between employment adjustment and mental health outcomes among family caregivers, and to test family-to-work role conflict as a mediator and workplace support as a moderator in this relationship. Data (n = 1,696) were drawn from the 2012 Canada General Social Survey: Caregiving and Care Receiving. Findings suggest that employment adjustment is significantly associated with negative mental health outcomes including worse self-rated mental health and higher life stress level. In addition, family-to-work role conflict mediates between employment adjustment and mental health outcomes, with the mediating effect as significant at all levels of workplace support and as weak with increasing workplace support. The findings highlight the role of family-to-work role conflict in understanding the influence of employment adjustment on family caregiver's mental health, and the implication of workplace support on promoting caregiver-friendly workplace culture to alleviate family-to-work role conflict thereby resulting in better mental health outcomes.

Perceptions of neighborhood safety and depressive symptoms among older minority urban subsidized housing residents: the mediating effect of sense of community belonging.

OBJECTIVES: Older minority subsidized housing residents represent a population that is particularly vulnerable to depression. Although research suggests that neighborhood characteristics influence older adults' mental health, it has not been explored in this target population. Drawing on social disorganization and social capital theories, this study's aim was to explore if perceptions of neighborhood safety are associated with depressive symptoms; and, whether a sense of community belonging has a mediating effect on this potential relationship. METHODS: The data are from interviews with 216 older adults (50% Black, 45% Latino/a) living in a U.S. urban subsidized housing development. RESULTS: Among participants, 80% identified feeling 'very safe' during the day while 63% expressed feeling 'very safe' at night in their neighborhood. Approximately 60% possessed a stronger sense of community belonging and 26% had clinically relevant depressive symptoms. Hierarchical regression analyses revealed that perceptions of feeling less safe in one's neighborhood were significantly associated with elevated levels of depressive symptoms; however, a greater sense of community belonging buffered (or had a significant mediating effect on) this relationship. CONCLUSION: The findings suggest the importance of continued exploration of the role of social capital in relation to feelings of safety in later life.

Accumulation of Microcystin (LR, RR and YR) in Three Freshwater Bivalves in Microcystis aeruginosa Bloom Using Dual Isotope Tracer.

Abstract: Stable isotope tracers were first applied to evaluate the Microcystis cell assimilation efficiency of Sinanodonta bivalves, since the past identification method has been limited to tracking the changes of each chl-a, clearity, and nutrient. The toxicity profile and accumulation of MC-LR, -RR and -YR in different organs (foot and digestive organs) from the three filter-feeders (Sinanodonta woodina, Sinanodonta arcaeformis, and Unio douglasiae) were assessed under the condition of toxigenic cyanobacteria (Microcystis aeruginosa) blooms through an in situ pond experiment using 13C and 15N dual isotope tracers. Chl-a concentration in the manipulated pond was dramatically decreased after the beginning of the second day, ranging from 217.5 to 15.6 µg·L-1. The highest amount of MCs was incorporated into muscle and gland tissues in U. douglasiae during the study period, at nearly 2 or 3 times higher than in S.woodiana and S. arcaeformis. In addition, the incorporated 13C and 15N atom % in the U. douglasiae bivalve showed lower values than in other bivalves. The results demonstrate that U. douglasiae has less capacity to assimilate toxic cyanobacteria derived from diet. However, the incorporated 13C and 15N atom % of S. arcaeformis showed a larger feeding capacity than U. douglasiae and S. wodiana. Our results therefore also indicate that S. arcaeformis can eliminate the toxin more rapidly than U. douglasiae, having a larger detoxification capacity.

Financial Care for Older Adults With Dementia.

This article describes an examination of the sociodemographic characteristics of adult children, particularly Baby Boomer caregivers, who provide financial care to older parents with dementia. The sample including 1,011adult children dementia caregivers aged 50 to 64 years is selected from a nationally representative sample in the 2010 Health and Retirement Study. Exact logistic regression revealed that race, provision of financial assistance to caregiver children, and the number of their children are significantly associated with financial caregiving of parents. Non-White caregivers are more likely to provide financial care to their parents or parents-in-law with dementia; those who have more children and provide financial assistance to their children are less likely to provide financial care to parents with dementia. The current findings present valuable new information on the sociodemographic characteristics of adult children who provide financial assistance to parents with dementia and inform research, programs, and services on dementia caregiving.

Seasonal Changes in Mycosporine-Like Amino Acid Production Rate with Respect to Natural Phytoplankton Species Composition.

After in situ incubation at the site for a year, phytoplanktons in surface water were exposed to natural light in temperate lakes (every month); thereafter, the net production rate of photoprotective compounds (mycosporine-like amino acids, MAAs) was calculated using (13)C labeled tracer. This is the first report describing seasonal variation in the net production rate of individual MAAs in temperate lakes using a compound-specific stable isotope method. In the mid-latitude region of the Korean Peninsula, UV radiation (UVR) usually peaks from July to August. In Lake Paldang and Lake Cheongpyeong, diatoms dominated among the phytoplankton throughout the year. The relative abundance of Cyanophyceae (Anabaena spiroides) reached over 80% during July in Lake Cheongpyeong. Changes in phytoplankton abundance indicate that the phytoplankton community structure is influenced by seasonal changes in the net production rate and concentration of MAAs. Notably, particulate organic matter (POM) showed a remarkable change based on the UV intensity occurring during that period; this was because of the fact that cyanobacteria that are highly sensitive to UV irradiance dominated the community. POM cultured in Lake Paldang had the greatest shinorine (SH) production rate during October, i.e., 83.83 ± 10.47 fgC·L(-1)·h(-1). The dominance of diatoms indicated that they had a long-term response to UVR. Evaluation of POM cultured in Lake Cheongpyeong revealed that there was an increase in the net MAA production in July (when UVR reached the maximum); a substantial amount of SH, i.e., 17.62 ± 18.34 fgC·L(-1)·h(-1), was recorded during this period. Our results demonstrate that both the net production rate as well as the concentration of MAAs related to photoinduction depended on the phytoplankton community structure. In addition, seasonal changes in UVR also influenced the quantity and production of MAAs in phytoplanktons (especially Cyanophyceae).

Identification of key factors influencing primary productivity in two river-type reservoirs by using principal component regression analysis.

To understand the factors controlling algal production in two lakes located on the Han River in South Korea, Lake Cheongpyeong and Lake Paldang, a principal component regression model study was conducted using environmental monitoring and primary productivity data. Although the two lakes were geographically close and located along the same river system, the main factors controlling primary productivity in each lake were different: hydraulic retention time and light conditions predominantly influenced algal productivity in Lake Cheongpyeong, while hydraulic retention time, chlorophyll a-specific productivity, and zooplankton grazing rate were most important in Lake Paldang. This investigation confirmed the utility of principal component regression analysis using environmental monitoring data for predicting complex biological processes such as primary productivity; in addition, the study also increased the understanding of explicit interactions between environmental variables. The findings obtained in this research will be useful for the adaptive management of water reservoirs. The results will also aid in the development of management strategies for water resources, thereby improving total environmental conservation.
