The Whole Package: A Multi-Component Smoking Cessation Intervention for Adults With Serious Mental Illness: A Qualitative Study.

Introduction: Smoking is one of the most important modifiable risk factors for excess morbidity and mortality in adults with serious mental illness (SMI). Many smokers with SMI are reportedly motivated to quit, however success rates among these smokers remain low and evidence-based treatment targeting this vulnerable group is limited. The purpose of this paper is to report the results of a qualitative inquiry of participants. Methods: We conducted a pilot two-arm randomized controlled trial (RCT) targeting adults with SMI. Our smoking cessation intervention included: (a) group-based physical activity (PA) game intervention (50 minutes, 3X/week for 12 weeks), (b) pharmacotherapy (bupropion or nicotine replacement therapy), and (c) smoking cessation counseling. Upon completion of the program, participants in the active and control groups completed a qualitative semi-structured interview in order to determine how the program impacted their smoking cessation. Grounded Theory methodology guided our data collection and analysis. Results: Twenty participants completed an interview. Participants described how the "whole package" of the 3 components of the intervention were critical to their smoking cessation process. The group-based program provided the structure, resources, and encouragement needed to start the process of quitting. Conclusion: Adults with SMI need support, resources, and engaging activities as they begin quitting and practice the skills needed to quit.

Associations of Systemic Inflammation and Senescent Cell Biomarkers with Clinical Outcomes in Older Adults with Schizophrenia.

Individuals with schizophrenia suffer from higher morbidity and mortality throughout life partly due to acceleration of aging-related diseases and conditions. Systemic inflammation is a hallmark of aging and is also observed in schizophrenia. An improved understanding of how inflammation and accelerated aging contribute to long-term health outcomes in schizophrenia could provide more effective treatments to preserve long-term cognitive and physical function. In this pilot cross-sectional study, 24 older adults (≥55 years old) with schizophrenia were assessed on symptoms (Positive and Negative Syndrome Scale), neurocognition (Matrics Consensus Cognitive Battery), mobility (Timed Get Up and Go), and general health (SF-12). Serum levels of 112 different cytokines were measured, from which we derived estimated senescence-associated secretory phenotype (SASP) scores for each participant. Two-tailed Pearson's bivariate correlations were computed to test the associations between schizophrenia clinical outcomes with individual cytokines, and SASP. Higher levels of eotaxin, IL-1α, IL-1ß, and IFNα are associated with both worse PANSS negative and depressive symptoms scores. IL-1α and IL-1ß negatively associated with general physical health whereas eotaxin negatively associated with mobility and global cognition. Overall, we found that specific inflammatory cytokines, but not composite measurements of SASP, are associated with clinical outcomes in older adults with schizophrenia.

Social connections as determinants of cognitive health and as targets for social interventions in persons with or at risk of Alzheimer's disease and related disorders: a scoping review.

BACKGROUND: Social connections have a significant impact on health across age groups, including older adults. Loneliness and social isolation are known risk factors for Alzheimer's disease and related dementias (ADRD). Yet, we did not find a review focused on meta-analyses and systematic reviews of studies that had examined associations of social connections with cognitive decline and trials of technology-based and other social interventions to enhance social connections in people with ADRD. STUDY DESIGN: We conducted a scoping review of 11 meta-analyses and systematic reviews of social connections as possible determinants of cognitive decline in older adults with or at risk of developing ADRD. We also examined eight systematic reviews of technology-based and other social interventions in persons with ADRD. STUDY RESULTS: The strongest evidence for an association of social connections with lower risk of cognitive decline was related to social engagement and social activities. There was also evidence linking social network size to cognitive function or cognitive decline, but it was not consistently significant. A number of, though not all, studies reported a significant association of marital status with risk of ADRD. Surprisingly, evidence showing that social support reduces the risk of ADRD was weak. To varying degrees, technology-based and other social interventions designed to reduce loneliness in people with ADRD improved social connections and activities as well as quality of life but had no significant impact on cognition. We discuss strengths and limitations of the studies included. CONCLUSIONS: Social engagement and social activities seem to be the most consistent components of social connections for improving cognitive health among individuals with or at risk for ADRD. Socially focused technology-based and other social interventions aid in improving social activities and connections and deserve more research.

Role Identity Transition: A Conceptual Framework for Being the Spouse of a Person With Early Onset Dementia.

Informal caregivers of persons with early onset dementia (PWEOD) are usually the spouses of affected individuals. These caregivers face unique challenges related to the unexpected nature of disease onset at this early life stage along with the accompanying symptoms, which can be different from those in late onset dementia. The current study explores the meanings these caregivers make of their situations and actions in response to their experiences. Findings provide a basis for development of a conceptual framework illustrating the basic, psychosocial processes underlying their shared situation. Grounded theory methodology was used. Qualitative data were collected through semi-structured interviews with 15 participants. Data were analyzed using constant comparative techniques and situational analysis. A distinction was made across participants between identifying as spouse versus caregiver for their PWEOD. Each participant had made or was making an identity transition from viewing their role as becoming more caregiver-like toward an eventual, complete shift to that of caregiver in a stepwise fashion. Incremental shifts in identity reflected challenges to the notion held of what it means to be a spouse. Results support prior research highlighting the unique experiences of caregivers of PWEOD while providing a framework for understanding the unique situations of these care-givers. Findings also inform nursing interventions tailored for spouses of PWEOD. [Journal of Gerontological Nursing, 49(8), 27-34.].

Review of Major Social Determinants of Health in Schizophrenia-Spectrum Psychotic Disorders: I. Clinical Outcomes.

BACKGROUND: Social determinants of health (SDoHs) are receiving growing attention and are particularly relevant to persons with schizophrenia-spectrum psychotic disorders (SSPDs), considering their heightened risk of comorbidities, cognitive and functional decline, and early mortality. Yet, we did not find any comprehensive review of multiple SDoHs in SSPD. STUDY DESIGN: We conducted a scoping review of meta-analyses and systematic reviews of nine major SDoHs in SSPD. STUDY RESULTS: Childhood abuse, parental psychopathology, parental communication problems, bullying, and urban settings with lower socioeconomic status were major risk factors for the greater incidence of SSPD and/or worse health. Social network size was inversely associated with overall psychopathology and negative symptoms. Experiences of racial/ethnic discrimination correlated with the prevalence of psychotic symptoms and experiences. Compared to native populations, the risk of psychosis was higher in immigrants, refugees, and asylees. Social fragmentation was associated with an increased prevalence of schizophrenia. Homeless populations had a 30-fold higher prevalence of schizophrenia than the general population. Seriously mentally ill people were 2.7 times more likely to report food insecurity than controls. The prevalence of non-affective psychosis in prisoners was 2.0%-6.5%, compared to 0.3% in the general population. Certain potentially positive factors like family and community resilience remain poorly studied. CONCLUSIONS: SDoHs are associated with higher rates of and worse outcomes in SSPD. Well-designed longitudinal studies are needed to understand SDoHs' contribution to health in persons with SSPD, to develop interventions, and to implement changes in clinical care and public health policies that would reduce adverse health impacts of SDoHs. Positive SDoHs deserve greater attention.

Education Mediates Racial Disparities in Cognitive Impairment Among Older Adults With Schizophrenia.

OBJECTIVES: In the general population, the construct of race is associated with disparities in cognitive aging. There are notable racial group disparities and inequities among people living with schizophrenia (PLWSz). Despite the salience of the construct of race in schizophrenia, there remains a knowledge gap about racial disparities in cognitive impairment among older adults in this vulnerable population. Our study uses mediation analysis to examine racial disparities in cognitive impairment among older adults with schizophrenia. METHODS: We assess global cognition in PLWSz over age 55 with the Measurement and Treatment Research to Improve Cognition in Schizophrenia cognitive test battery in our "all-comer" sample (N = 64). The primary exposure is self-reported racial group. We examine mediation of cognitive impairment through educational attainment, adjusting for psychiatric illness severity, history of substance use, and vascular risk factors. RESULTS: There was a Black/non-Black group racial disparity in global cognitive score (-2.8, 95% CI: -4.4, -1.3) after adjusting for confounding and interaction. This disparity was significantly mediated by years of education. CONCLUSIONS: There are notable racial disparities in cognitive impairment among older adults with schizophrenia; however, differences in cognitive scores between racial groups are mediated by level of education. CLINICAL IMPLICATIONS: Social determinants of health, particularly educational attainment, are important risk factors for cognitive impairment in PLWSz and should be considered by clinicians. Early screening and assessment of cognitive symptoms is essential to addressing health disparities/inequalities among older adults living with schizophrenia.

The Epidemiology of Smoking in Older Adults: A National Cohort Study.

BACKGROUND: Older smokers account for the greatest tobacco-related morbidity and mortality in the USA, while quitting smoking remains the single most effective preventive health intervention for reducing the risk of smoking-related illness. Yet, knowledge about patterns of smoking and smoking cessation in older adults is lacking. OBJECTIVE: Assess trends in prevalence of cigarette smoking between 1998 and 2018 and identify patterns and predictors of smoking cessation in US older adults. DESIGN: Retrospective cohort study PARTICIPANTS: Individuals aged 55+ enrolled in the nationally representative Health and Retirement Study, 1998-2018 MAIN MEASURES: Current smoking was assessed with the question: "Do you smoke cigarettes now?" Quitting smoking was defined as having at least two consecutive waves (between 2 and 4 years) in which participants who were current smokers in 1998 reported they were not currently smoking in subsequent waves. KEY RESULTS: Age-adjusted smoking prevalence decreased from 15.9% in 1998 (95% confidence interval (CI) 15.2, 16.7) to 11.2% in 2018 (95% CI 10.4, 12.1). Among 2187 current smokers in 1998 (mean age 64, 56% female), 56% of those living to age 90 had a sustained period of smoking cessation. Smoking less than 10 cigarettes/day was strongly associated with an increased likelihood of quitting smoking (subdistribution hazard ratio 2.3; 95% CI 1.9, 2.8), compared to those who smoked more than 20 cigarettes/day. CONCLUSIONS: Smoking prevalence among older persons has declined and substantial numbers of older smokers succeed in quitting smoking for a sustained period. These findings highlight the need for continued aggressive efforts at tobacco cessation among older persons.

A Group Videogame-Based Physical Activity Program Improves Walking Speed in Older Adults Living With a Serious Mental Illness.

Background and Objectives: One of the most overlooked populations in our society and in health care are middle-aged and older adults living with a serious mental illness (SMI) despite the growing numbers of this population. Health care communities, including both inpatient and outpatient mental health programs, have a responsibility to provide care that nurtures clients' mental as well as physical health needs. Providing accessible and engaging physical activity programs is an excellent way to provide this type of holistic care. The purpose of this article is to describe the impact of a pilot videogame-based physical activity program on walking speed in older adults with SMI. Research Design and Methods: A one-group pretest post-test pilot study was conducted with a sample of 52 older adults with SMI recruited from community-based mental health programs. Participants played an active videogame (using the Kinect for Xbox 360 game system; Microsoft, Redmond, WA) for 50-minute group sessions 3 times a week for 10 weeks. Walking speed was assessed with the timed 3-m walk from the Short Physical Performance Battery at enrollment, 5 weeks, and 10 weeks. Results: Participants achieved statistically significant improvement in walking speed (0.10 m/s, bias-corrected confidence interval Lower Limit (LL) 0.04, Upper Limit (UL) 0.15) over a 10-week period. This change represents a clinically and statistically (p ≤ .05) significant improvement in walking speed. Best estimates for clinically meaningful changes in walking speed are 0.05 m/s for a small change and 0.10 m/s for a substantial change. Discussion and Implications: Results suggest that engagement in a group videogame-based physical activity program has the potential to improve walking speed in older adults with SMI. In turn, walking speed is an important indicator of premature mortality and cardiorespiratory fitness.

Impact of exergames on psychiatric symptoms in older adults with serious mental illness.

OBJECTIVES: Older adults with serious mental illness (SMI) are more likely to have high body mass index (BMI) and chronic conditions such as cardiovascular disease and diabetes. A sedentary lifestyle, which may be attributed to pharmacologic side effects and the symptoms of mental illness, has been difficult to treat. Patients experiencing negative symptoms (e.g. apathy, anhedonia) may be more likely to exercise in a group setting with activities that are designed to stimulate the mind and encourage engagement. "Exergames," or exercise-based videogames, are an interactive and stimulating method to provide aerobic activities. Exercise has also been shown to reduce the symptoms of depression. The purpose of this study is to evaluate the impact of a 10-week exergame program on depressive and negative symptoms in older adults with SMI. MATERIALS AND METHODS: A single-group pretest posttest study was conducted with 52 older adults diagnosed with SMI. Participants engaged in group exergame activities for 50-minute sessions three times a week for 10 weeks. The Patient Reported Outcome Measurement Information System (PROMIS) and the Scale for the Assessment of Negative Symptoms (SANS) were conducted at enrollment, 5 weeks, and 10 weeks. RESULTS: Participants achieved statistically significant reductions in self-reported depressive symptoms (-0.83, LL -1.46, UL -0.12) and observed negative symptoms (-5.29, LL -7.67, UL -3.14) over a 10-week period. CONCLUSIONS: Our results suggest utilization of exergames as an adjunct treatment can be an effective, engaging, and cost-efficient method to reducing depressive and negative symptoms in older adults with SMI.

Telephone based smoking cessation intervention for adults with serious mental illness during the COVID-19 pandemic.

BACKGROUND: The high rates of smoking in adults with serious mental illness (SMI) increases risk for COVID-19 infection. The purpose of this paper is to present the results of a smoking cessation intervention that was adapted to be offered by phone during a Shelter in Place (SIP) period in San Francisco, California, at the beginning of the COVID-19 pandemic. METHODS: During the SIP, we offered counseling sessions by phone to five participants. At the end of each session, we assessed readiness to quit, tobacco cessation or reduction, and inquired about the impact of the shelter in place on smoking habits and mental health. Grounded theory guided data collection and analysis. RESULTS: The categories that emerged around barriers and facilitators for smoking cessation were COVID-19-related stressors, having purpose, structure and feelings of connections, and the importance of quitting aides for smoking cessation. CONCLUSION: Offering telephone based smoking cessation counseling to adults with SMI while they shelter in place may improve their readiness to quit.

Direct-to-consumer genomic testing: Are nurses prepared?

Genomic testing is increasingly common in the consumer marketplace. The role of nurses in educating and counseling patients requires them to be prepared to respond to questions about the results of direct-to-consumer genomic testing. This article describes one individual's reflections upon undergoing this testing, the challenges of interpreting the results, and nursing considerations for integrating these results into clinical practice.

The Lived Experience of Older Adults With Type 2 Diabetes Mellitus and Diabetes-Related Distress.

An older, more diverse population and longer lifespans are major contributors to the anticipated tripling of diabetes prevalence by 2050. Diabetes-related distress affects up to 40% of people with diabetes and may be a higher risk for older adults due to greater prevalence of comorbidities. The objective of the current phenomenological study was to describe how diabetes-related distress might be uniquely experienced by older adults (age ≥65) with type 2 diabetes mellitus (T2DM). Interpretive phenomenology guided the research design and analysis. Everyday life experiences of living with T2DM and elevated diabetes distress were investigated with interpretive interviews. The most prevalent lived experiences were strained relationships with health care providers, guilt, fear, loneliness, and forgetfulness. These experiences created challenges in managing diabetes and increased diabetes-related distress. Improving knowledge regarding the lived experience of older adults with diabetes-related distress may allow health care providers to tailor treatment to this population, thus improving outcomes.

Play provides social connection for older adults with serious mental illness: A grounded theory analysis of a 10-week exergame intervention.

Introduction: The number of older adults with serious mental illness (SMI) is predicted to reach 15 million by 2030. Social isolation is known to contribute to morbidity and mortality, and those with SMI experience more social isolation than older adults in the general population. Social isolation in these older adults is complex and involves factors including organic psychopathology, effects of medications and/or other substances, medical co-morbidity, disability, and social stigma. The burgeoning field of inquiry of exergames, which are video games with gestural interfaces, for older adults has found that they are safe, effective, enjoyable, and may decrease social isolation. This qualitative study was conducted to gain insight into the effects of group exergame play on the psychosocial wellbeing of older adults with SMI.Methods: We explored the psychosocial effects of a 10-week group exergame program for 16 older adults with SMI using grounded theory methodology within a symbolic interactionist framework.Results: Participants experienced positive social contact, engaged in social attunement, and expressed motivation to take risks and face problem-solving and physical challenges. Two interrelated concepts emerged from the integrated data: Social connectedness and competence. The theoretical construct that was abducted from these concepts was that play and playfulness were the vehicle for many interacting social processes to take place.Conclusion: Group play through exergames for older adults with SMI may promote recovery and healthy aging by increasing social integration, improving self-efficacy, and promoting physical health through exercise.

"Looking Forward": a qualitative evaluation of a physical activity program for middle-aged and older adults with serious mental illness.

OBJECTIVES: Older adults with serious mental illness (SMI) often have poor physical health in addition to serious mental health issues. Sustained engagement in a group physical activity program may provide necessary physical and mental health benefits. The purpose of this report is to describe participants' feedback about a video game-based group physical activity program using the Kinect for Xbox 360 game system (Microsoft, Redmond, WA). In particular, we wanted to understand what worked about the program, what was not ideal, and how it impacted their lives. DESIGN: Semi-structured interviews were collected and analyzed with grounded theory methodology. SETTING: Mental health facility. PARTICIPANTS: Sixteen older adults with SMI. MEASUREMENTS: Participants played an active video game for 50-minute sessions, three times a week for 10 weeks. Qualitative interviews were conducted with 16 participants upon completion of the program. RESULTS: Participants expressed enthusiasm for the physical activity program, indicating it was an activity that they looked forward to doing. The results of the study provide insight into how the program may be implemented into practice at mental health facilities. Three implementation to practice categories were identified: (1) programmatic considerations, such as when to hold the groups and where; (2) the critical importance of staff involvement; and (3) harnessing patients' interest in the program. CONCLUSION: Our results suggest that engagement in an intense video game-based group physical activity program has a positive impact on participants' overall health. The group atmosphere, staff involvement, availability of the program at a mental health facility, and health benefits were critical.

Tools You'll Have for the Rest of Your Life: A Qualitative Evaluation of a Fitness and Vocational Training Program for Substance Use Recovery.

Introduction: Substance use disorder (SUD) is a problem within the United States and warrants attention. Despite growing concerns, there exists a research-to-practice gap in the implementation of evidence-based treatment strategies, particularly in the area of physical activity as a low-cost adjunct to treatment programs. Additionally, people with SUD often face challenges in re-entering the workforce, due to multiple factors including long absences, incarceration, or lack of experience and training. Method: Our group conducted focus group interviews with 26 participants to evaluate a 12-week fitness and health education program (Live Fitness) using grounded theory methodology. Live Fitness also served as a vocational training opportunity in collaboration with a large fitness facility and a residential SUD treatment program. Results: Three broad categories emerged from the focus group interviews: The program serves as an aide for recovery, confers physical benefits from participation, and helps participants feel that they are part of the community with a way to ease back into life. Conclusion: The results of our study suggest that treatment centers should invest attention and resources into guided fitness programs and that programs with an emphasis in vocational training should continue to be explored.

Symptom Experience of Older Adults With Type 2 Diabetes and Diabetes-Related Distress.

BACKGROUND: An older, more diverse population and longer life spans are major contributors to the anticipated tripling of Type 2 diabetes prevalence by 2050. Diabetes-related distress affects up to 40% of people diagnosed with Type 2 diabetes and may be a greater risk for older adults due to greater prevalence of comorbidities. OBJECTIVE: The objective of this phenomenological study was to describe how diabetes-related distress in older adults (≥65 years) with Type 2 diabetes might be uniquely experienced. METHODS: Participants were recruited using convenience sampling and snowball sampling. Interpretive phenomenology guided the research design and analysis. With interpretive interviews, we investigated the everyday health, symptoms, and life experiences of living with Type 2 diabetes and elevated diabetes distress. RESULTS: Among the older adults in this study, the most prevalent symptoms were fatigue, hypoglycemia, diarrhea, pain, loss of balance, and falling. These diabetes-related symptoms led to substantial loss of independence, decreased quality of life, and constrained social lives due to restricted activities. DISCUSSION: Diabetes-related distress presents with some unique symptoms and responses in older adults. Improving knowledge regarding the symptom experience of older adults with diabetes-related distress may allow healthcare providers to tailor treatment and thus improve outcomes for older adults struggling with diabetes.

A review of the literature on symptom clusters in studies that included oncology patients receiving primary or adjuvant chemotherapy.

AIMS AND OBJECTIVES: To summarise the current state of knowledge of symptom clusters research from studies that included, as part of their sample, patients who were receiving primary or adjuvant chemotherapy. BACKGROUND: Since the concept of a symptom cluster was first introduced into the oncology literature in 2001, only four comprehensive reviews of symptom clusters research in oncology patients were identified that provide insights into this important concept in symptom management research. DESIGN: A comprehensive review of the literature. METHODS: A comprehensive literature search was conducted for the years 2000 to 2016. Only 19 studies met the inclusion criteria for this literature review. These studies were evaluated in terms of the symptom assessment instruments used; the statistical analysis methods used; the symptom dimension(s) used to create the symptom cluster(s); the number and types of symptom clusters identified; and whether the specific symptom clusters changed over time. RESULTS: The number of symptom clusters identified ranged from one-seven. The majority of the studies used some type of factor analysis to create the symptom clusters. The most common symptom dimension used to create the clusters was symptom severity. A "gastrointestinal symptom cluster" was the most common symptom cluster identified. Across the eight longitudinal studies, for half of these studies the symptom clusters remained relatively stable over time. CONCLUSIONS: Additional research is needed in oncology patients to address the assessment of symptom clusters, the specific nature of symptom clusters and whether symptom clusters change over time.

Stability of Symptom Clusters in Patients With Breast Cancer Receiving Chemotherapy.

CONTEXT: Patients with breast cancer who undergo chemotherapy (CTX) experience between 10 and 32 concurrent symptoms. An evaluation of how these symptoms cluster together and how these symptom clusters change over time may provide insights into how to treat these multiple co-occurring symptoms. OBJECTIVES: The purposes of this study were to determine the occurrence rates and severity ratings for 38 common symptoms, evaluate for differences in the number and types of symptom clusters, and evaluate for changes over time in these symptom clusters (i.e., before CTX, the week after CTX, and two weeks after CTX). METHODS: At each of the assessments, a modified version of the Memorial Symptom Assessment Scale was used to assess the occurrence and severity of the 38 symptoms. Exploratory factor analyses were used to extract the symptom clusters. RESULTS: Although across the two symptom dimensions (i.e., occurrence and severity) and the three assessments, eight distinct symptom clusters were identified, only five were relatively stable across both dimensions and across time (i.e., psychological, hormonal, nutritional, gastrointestinal, and epithelial). Two of the additional clusters varied by time but not by symptom dimension (i.e., sickness behavior and weight change). The CTX neuropathy cluster was identified only at the assessment performed in the week after CTX. CONCLUSION: These findings provide insights into the most common symptom clusters in patients undergoing CTX for breast cancer. In addition, the most common symptoms within each cluster appear to be relatively stable across the two dimensions, as well as across time.

Serum BDNF Is Positively Associated With Negative Symptoms in Older Adults With Schizophrenia.

OBJECTIVES: Older adults with chronic schizophrenia are at greater risk for functional disability and poorer health outcomes than those without serious mental illness. These individuals comprise 1-2% of the elderly population in the United States and are projected to number approximately 15 million by 2030. The symptoms of schizophrenia can be disabling for individuals, significantly reducing quality of life. Often, the negative symptoms (NS) are the most resistant to treatment and are considered a marker of illness severity, though they are challenging to measure objectively. Biomarkers can serve as objective indicators of health status. Brain-derived neurotrophic factor (BDNF) is a potential biomarker for schizophrenia and may serve as an important indicator of illness severity. METHODS: A cross-sectional study with 30 older adults with chronic schizophrenia. Participants were assessed on serum levels of BDNF and psychiatric symptoms (Positive and Negative Syndrome Scale). Pearson's bivariate correlations (two-tailed) and linear regression models were used. RESULTS: A significant positive association ( p < .05) was found between higher serum levels of BDNF and greater severity for the NS items of passive, apathetic, social withdrawal, and emotional withdrawal. In multivariate analyses, the association remained significant. CONCLUSIONS: Although the association between BDNF and NS was not in the expected direction, the data corroborate findings from previous work in patients with schizophrenia. It is possible that higher serum levels of BDNF reflect compensatory neuronal mechanisms resulting from neurodevelopmental dysfunction.
