Abstract

This chapter explores the case of eight-year-old Suzanna, who is presented to the primary care office with a complaint of a sore throat for 2 days. Suzanna complains that she has pain when she swallows. She also complains of a headache. Both the throat pain and headache are relieved slightly with the use of over-the-counter pain relievers. She usually has no problems falling or staying asleep but since the throat pain has started, her sleep has been interrupted. The chapter provides essential guidance and information for understanding how to diagnose and manage this case. This includes differential diagnosis and a series of critical thinking questions ideal for the family nurse practitioner.

Abstract

Importance: Inappropriate use of antipsychotic medications in nursing homes is a growing public health concern. Residents exposed to higher levels of socioeconomic deprivation in the area around a nursing home may be currently exposed, or have a long history of exposure, to more noise pollution, higher crime rates, and have less opportunities to safely go outside the facility, which may contribute to psychological stress and increased risk of receiving antipsychotic medications inappropriately. However, it is unclear whether neighborhood deprivation is associated with use of inappropriate antipsychotic medications and whether this outcome is different by facility staffing levels. Objective: To evaluate whether reported inappropriate antipsychotic medication use differs in severely and less severely deprived neighborhoods, and whether these differences are modified by higher levels of total nurse staffing. Design, Setting, and Participants: This was a cross-sectional analysis of a national sample of nursing homes that linked across 3 national large-scale data sets for the year 2019. Analyses were conducted between April and June 2023. Exposure: Neighborhood deprivation status (severe vs less severe) and total staffing hours (registered nurse, licensed practical nurse, certified nursing assistant). Main Outcome and Measures: This study estimated the association between neighborhood deprivation and the percentage of long-stay residents who received an antipsychotic medication inappropriately in the nursing home at least once in the past week and how this varied by nursing home staffing through generalized estimating equations. Analyses were conducted on the facility level and adjusted for state fixed effects. Results: This study included 10966 nursing homes (1867 [17.0%] in severely deprived neighborhoods and 9099 [83.0%] in less deprived neighborhoods). Unadjusted inappropriate antipsychotic medication use was greater in nursing homes located in severely deprived neighborhoods (mean [SD], 15.9% [10.7%] of residents) than in those in less deprived neighborhoods (mean [SD], 14.2% [8.8%] of residents). In adjusted models, inappropriate antipsychotic medication use was higher in severely deprived neighborhoods vs less deprived neighborhoods (19.2% vs 17.1%; adjusted mean difference, 2.0 [95% CI, 0.35 to 3.71] percentage points) in nursing homes that fell below critical levels of staffing (less than 3 hours of nurse staffing per resident-day). Conclusions and Relevance: These findings suggest that levels of staffing modify disparities seen in inappropriate antipsychotic medication use among nursing homes located in severely deprived neighborhoods compared with nursing homes in less deprived neighborhoods. These findings may have important implications for improving staffing in more severely deprived neighborhoods..

Abstract

Oral squamous cell carcinoma (OSCC) presents significant treatment challenges due to its poor survival and intense pain at the primary cancer site. Cancer pain is debilitating, contributes to diminished quality of life, and causes opioid tolerance. The stimulator of interferon genes (STING) agonism has been investigated as an anti-cancer strategy. We have developed STINGel, an extended-release formulation that prolongs the availability of STING agonists, which has demonstrated an enhanced anti-tumor effect in OSCC compared to STING agonist injection. This study investigates the impact of intra-tumoral STINGel on OSCC-induced pain using two separate OSCC models and nociceptive behavioral assays. Intra-tumoral STINGel significantly reduced mechanical allodynia in the orofacial cancer model and alleviated thermal and mechanical hyperalgesia in the hind paw model. To determine the cellular signaling cascade contributing to the antinociceptive effect, we performed an in-depth analysis of immune cell populations via single-cell RNA-seq. We demonstrated an increase in M1-like macrophages and N1-like neutrophils after STINGel treatment. The identified regulatory pathways controlled immune response activation, myeloid cell differentiation, and cytoplasmic translation. Functional pathway analysis demonstrated the suppression of translation at neuron synapses and the negative regulation of neuron projection development in M2-like macrophages after STINGel treatment. Importantly, STINGel treatment upregulated TGF-β pathway signaling between various cell populations and peripheral nervous system (PNS) macrophages and enhanced TGF-β signaling within the PNS itself. Overall, this study sheds light on the mechanisms underlying STINGel-mediated antinociception and anti-tumorigenic impact.

Abstract

INTRODUCTION: Professional caregivers (nursing assistants and personal care aides) in nursing homes (NH) and assisted living (AL) provide the majority of long-term residential care for persons with Alzheimer's disease and related dementias. Their work is stressful, but until recently, no measures were available to assess stress in this workforce. Using the new Long-Term Care Cope (LTC COPE) scale, this study evaluates the relationship of coping with staff demographic characteristics and outcomes; the findings can be used to develop and evaluate interventions to improve staff well-being. METHODS: We used a cross-sectional online questionnaire completed by professional caregivers working in a purposive selection of 10 NHs and three AL communities in California, New York, and North Carolina. The sample included 391 professional caregivers and had a representative distribution by age; it was 87% female; 42% non-Hispanic/Latinx (NHL) Black, 25% NHL White, 20% Hispanic/Latinx, and 7% NHL Asian. Worker job satisfaction, mental health, and health-related quality of life were examined in relation to caregiver demographics and the following approaches to coping as measured by the LTC COPE: avoidance, adaptive psychological strategies, active engagement, maladaptive psychological strategies, minimizing emotional impact, and substance use. Statistical comparisons used non-parametric Spearman correlation coefficients. RESULTS: Little difference in coping strategies was noted by sex and education; older caregivers used adaptive psychological strategies more than younger caregivers; and traditionally minoritized adults (NHL Black, NHL Asian, and Hispanic/Latinx), compared to NHL White adults, more often used adaptive and less often used maladaptive psychological coping strategies. The use of maladaptive and avoidance strategies was strongly associated with depressive symptoms, anxiety, and burnout. DISCUSSION: Professional caregivers report using a wide variety of coping strategies, with multiple strategies being the norm, and both adaptive/engaged and maladaptive/disengaged approaches are common. Certain coping approaches are strongly linked to depression, anxiety, and burnout; attention to training and support of adaptive and positive coping may augment other efforts to improve job satisfaction and performance. The LTC COPE scale has the potential to guide and evaluate practices to improve workers’ well-being. Highlights: Professional caregivers in nursing homes and assisted living generally use multiple strategies to cope with work-related stress. Certain coping approaches are strongly linked to depression, anxiety, and burnout. The Long-Term Care Cope scale has potential to guide and evaluate practices to improve worker well-being.

Abstract

Background: Black women in the United States (US) have the highest risk of preterm birth (PTB) and small for gestational age (SGA) births, compared to women of other racial groups. Among Black women, there are disparities by nativity whereby foreign-born women have a lower risk of PTB and SGA compared to US-born women. Differential exposure to racism may confer nativity-based differences in adverse perinatal outcomes between US- and foreign-born Black women. This remains unexplored among US- and African-born women in California. Objectives: Evaluate the relationship between structural racism, nativity, PTB and SGA among US- and African-born Black women in California. Methods: We conducted a population-based study of singleton births to US- and African-born Black women in California from 2011 to 2017 (n = 131,424). We examined the risk of PTB and SGA by nativity and neighbourhoods with differing levels of structural racism, as measured by the Index of Concentration at the Extremes. We fit crude and age-adjusted Poisson regression models, estimated using generalized estimating equations, with risk ratios (RR) and 95% confidence intervals (CI) as the effect measure. Results: The proportions of PTB and SGA were 9.7% and 14.5%, respectively, for US-born women, while 5.6% and 8.3% for African-born women. US-born women (n = 24,782; 20.8%) were more likely to live in neighbourhoods with high structural racism compared to African-born women (n = 1474; 11.6%). Structural racism was associated with an elevated risk of PTB (RR 1.19, 95% CI 1.12, 1.26) and SGA (RR 1.19, 95% CI 1.13, 1.25) for all Black women, however, there was heterogeneity by nativity, with US-born women experiencing a higher magnitude of effect than African-born women. Conclusions: Among Black women in California, exposure to structural racism and the impacts of structural racism on the risk of PTB and SGA varied by nativity.

Abstract

Background: Chinese American immigrants have been underrepresented in health research partly due to challenges in recruitment. Objectives: This study aims to describe recruitment and retention strategies and report adherence in a 7-day observational physical activity study of Chinese American immigrants with prior gestational diabetes during the COVID-19 pandemic. Methods: Foreign-born Chinese women aged 18–45 years, with a gestational diabetes index pregnancy of 0.5–5 years, who were not pregnant and had no current diabetes diagnosis were recruited. They wore an accelerometer for 7 consecutive days and completed an online survey. Multiple recruitment strategies were used: (a) culturally and linguistically tailored flyers, (b) social media platforms (e.g., WeChat [a popular Chinese platform] and Facebook), (c) near-peer recruitment and snowball sampling, and (d) a study website. Retention strategies included flexible scheduling and accommodation, rapid communications, and incentives. Adherence strategies included a paper diary and/or automated daily text reminders with a daily log for device wearing, daily email reminders for the online survey, close monitoring, and timely problem-solving. Results: Participants were recruited from 17 states; 108 were enrolled from August 2020 to August 2021. There were 2,479 visits to the study webpage, 194 screening entries, and 149 inquiries about the study. Their mean age was 34.3 years, and the mean length of U.S. stay was 9.2 years. Despite community outreach, participants were mainly recruited from social media (e.g., WeChat). The majority were recruited via near-peer recruitment and snowball sampling. The retention rate was 96.3%; about 99% had valid actigraphy data, and 81.7% wore the device for 7 days. The majority of devices were successfully returned, and the majority completed the online survey on time. Discussion: We demonstrated the feasibility of recruiting and retaining a geographically diverse sample of Chinese American immigrants with prior gestational diabetes during the COVID-19 pandemic. Recruiting Chinese immigrants via social media (e.g., WeChat) is a viable approach. Nonetheless, more inclusive recruitment strategies are needed to ensure broad representation from diverse socioeconomic groups of immigrants.

Abstract

Purpose: Sexual and gender minority (SGM) people are at greater risk for substance use than heterosexual and cisgender people, but most prior work is limited by cross-sectional analyses or the examination of single substance use. This study examined substance use over time among SGM people to identify patterns of polysubstance use at the intersection of sex and gender. Methods: Data were collected annually over 4 years from SGM respondents (n = 11,822) in The Population Research in Identity and Disparities for Equality (PRIDE) Study. Differences in substance use patterns (any prior 30-day use of 15 substances) by gender subgroup were examined with latent class analysis, and multinomial regression models tested relationships between gender subgroup and substance use. Results: Eight classes of substance use were observed. The three most common patterns were low substance use (49%), heavy episodic alcohol use (≥5 alcoholic drinks on one occasion) with some cannabis and tobacco use (14%), and cannabis use with some tobacco and declining heavy episodic alcohol use (13%). Differences observed included lower odds of patterns defined by heavy episodic alcohol use with some cannabis and tobacco use in all gender subgroups relative to cisgender men and persons with low substance use (odds ratios [ORs] 0.26-0.60). Gender expansive people assigned female at birth, gender expansive people assigned male at birth, and transgender men had greater odds of reporting cannabis use with small percentages of heavy episodic alcohol and tobacco use (ORs: 1.41-1.60). Conclusion: This study suggests that there are unique patterns of polysubstance use over time among gender subgroups of SGM people.

Abstract

PURPOSE: To understand perceived facilitators and barriers older adults experienced in accessing coronavirus disease 2019 (COVID-19) vaccines. METHOD: An electronic survey was distributed to older adults and those familiar with experiences of older adults accessing COVID-19 vaccines. Analysis included descriptive statistics and directed content analysis of open-ended responses, guided by the National Institute on Aging Health Disparities Research Framework. RESULTS: Most participants (n = 294) identified as White (79.5%), 33.8% identified as Hispanic, 8.1% identified as Black, and 12.4% identified as Other. Two thirds of respondents were male (68.6%), and the median age was 67 years. Five key themes emerged: Availability and Accessibility, Information, Cost, Safety and Side Effects, and Sense of Security. CONCLUSION: Barriers and facilitators to accessing COVID-19 vaccines for older populations paralleled those seen in other demographics. Similar needs likely exist for access to other vaccines and health care in general. Vaccine rollouts, particularly in public health emergencies, must be carried out with care and an awareness of the barriers faced by vulnerable groups.

Abstract

Background: Despite updated American Heart Association guidelines, interventions designed to reduce telemetry misuse are uncommon. Local problem: There was a systemic failure within the institution to adopt the most recent guidelines, resulting in poor use of resources and downstream costs. Methods: Case-control. Pre-post educational intervention, quality-improvement (QI) project in an urban academic cancer institution. Baseline telemetry usage was observed in 2,984 nonintensive inpatients in 21 hospital services over 6 months. Outcome measures were weekly telemetry usage in total minutes and cost savings based on a costpredicted algorithm. Performance was compared between the intervention group and a control group for 3 months. Measures were compared using QI control charts and inferential statistics. Intervention: Three high-using telemetry services primarily staffed by certified nurse practitioners (CNPs) were provided with a telemetry education intervention. The intervention consisted of four ten-minute educational sessions over 2 weeks delivered to the highest three telemetry using services. Results: Forty-five providers received the educational intervention (78% CNPs and physician assistants [PAs] and 22% medical doctors [MDs]) and 272 did not (57% CNPs and PAs and 43% MDs). Only the educational intervention group showed measurable decreases shown by shifts in QI control charts. Decreased usage in the intervention group produced greater cost savings per patient when compared with the control group ($71.98 vs. $60.68), resulting in an estimated total annual cost savings of $94,740. Conclusions: Educational interventions for inpatient CNPs that reinforce national policies for telemetry discontinuation improve practice efficiency and potentially decrease health care costs.

Abstract

This study examined whether trajectories of perceived unmet needs for Home and Community-Based Services (HCBS) were associated with life satisfaction among Chinese older adults and whether the association was moderated by psychological resilience. Data came from five waves (2005-2018) of the Chinese Longitudinal Healthy Longevity Survey (CLHLS). Latent class growth analysis revealed three distinct trajectories of perceived unmet HCBS needs: “increasing” (n = 977, 36.24%), “persistent” (n = 570, 21.14%), and “decreasing” (n = 1149, 42.62%). Multiple regression estimates showed that the increasing group was associated with lower life satisfaction, and the association was moderated by psychological resilience, especially for older adults who were male, living in rural, and oldest-old. Results indicate that inequalities in cumulative exposure to perceived unmet HCBS needs may further lead to increasing inequalities in life satisfaction. Interventions focused on minimizing the provision-need gap of HCBS and enhancing personal resilience should be considered to improve the life satisfaction of older adults.

Abstract

In neonatal, symptomatic tetralogy of Fallot (sTOF), data are lacking on whether high-risk groups would benefit from staged (SR) or complete repair (CR). We studied the association of gestational age (GA) at birth and z-score for birth weight (BWz), with management strategy and outcomes in sTOF. California population-based cohort study (2011–2017) of infants with sTOF (defined as catheter or surgical intervention prior to 44 weeks corrected GA) was performed, comparing management strategy and timing by GA and BWz categories. Multivariable models evaluated composite outcomes and days alive and out of hospital (DAOOH) in the first year of life. Among 345 patients (SR = 194; CR = 151), management strategy did not differ by GA or BWz with complete repair defined as prior to 44 weeks corrected gestational age; however, did differ by GA with regard to complete/timely repair (defined as complete repair within first 30 days of life). Full-term and early-term neonates underwent CR 20 (95%CI: − 27.1, − 14.1; p < 0.001) and 15 days (95%CI: − 22.1, − 8.2; p < 0.001) sooner than preterm neonates. Prematurity and major anomaly were associated with mortality or non-cardiac morbidity, while only major anomaly was associated with mortality or cardiac morbidity (OR = 3.5, 95%CI: 1.8,6.7, p < .0001). Full-term infants had greater DAOOH compared to preterm infants (35.2 days, 95%CI: 4.0, 66.5, p = 0.03). LGA infants and those with major anomaly had significantly lower DAOOH. In sTOF, patient specific risk factors such as prematurity and major anomaly were more associated with outcomes than management strategy.

Abstract

Background: Dying in a preferred place is important for a good death. Currently, no study has evaluated the extent to which the preferences for the place of death (PoD) are met among terminal cancer patients in China. This study examined the congruence between the preferred and actual PoD and its predictors among terminal cancer patients in China. Methods: Between 2015 and 2023, 845 terminal cancer patients from four tertiary hospitals in Wuhan, China, were enrolled and followed till death. Face-to-face surveys at baseline and telephone-based interviews in the last month of patients’ lives were combined to learn patients’ preferred PoD. Data on patients’ actual PoD were collected from families within 1 month after patients’ death. Results: Of the 410 patients who died, 62.7% of them died in hospitals. The agreement between patients’ preferred and actual PoD was fair (κ = 0.221). The congruence between patients’ preferred and actual PoD was 63.0, 36.6%, and 0 for hospital death, home death, and hospice facility/nursing home death separately. Patients were more likely to die in their preferred places if their preferred place and family caregivers’ belief of patients’ preferred PoD was congruent (odds ratio [OR] = 6.464, p = 0.001), or if caregivers had a medically related occupation (OR = 4.577, p = 0.003); if patients were hospitalized at least twice in the last month of life (OR = 0.422, p = 0.000), or the quality of care received by patients in the last 48 h was rated good by the families (OR = 0.373, p = 0.011), patients were less likely to die in their preferred places. Conclusion: The congruence between patients’ preferred and actual PoD was fair. Advance care planning (ACP) needs to be popularized in China, and the quality of care in hospice facilities and nursing homes should be improved. The necessary policy support for hospice care should be made to respect cancer patients’ end-of-life (EoL) care preferences in China.

Abstract

Adherence Connection for Counseling, Education, and Support (ACCESS)-I is a peer-led mHealth antiretroviral therapy adherence intervention for adolescents and young adults living with HIV who are in treatment but have detectable viral loads. Participants received five online sessions with peer health coaches who followed a structured intervention manual. Peers maintained intervention fidelity but also engaged in casual discussion that was not directly related to ART adherence or HIV. We conducted a qualitative analysis of the casual interactions that occurred during the ACCESS I intervention. Sessions were transcribed and coded, and these casual interactions were then coded into 10 subcodes to document their content, and also coded for three types of social capital–emotional, informational, and instrumental. Emotional and Informational social capital codes were the most common, while instrumental codes were rare. Activities was the most common topic overall, while encouragement was more common in emotional social capital narratives and personal experience was more common in informational social capital narratives. These casual interactions may strengthen peer-participant relationships, building social capital that could then be used to encourage positive behavior change. Although social capital was not directly measured, these analyses illustrate the value of attending to seemingly casual interactions in peer-led interventions.

Abstract

Background Regular physical activity (PA) is a component of cardiovascular health and is associated with a lower risk of cardiovascular disease (CVD). However, only about half of US adults achieved the current PA recommendations. Objective The study purpose was to implement PA counseling using a clinical decision support tool in a preventive cardiology clinic and to assess changes in CVD risk factors in a sample of patients enrolled over 12 weeks of PA monitoring. Methods This intervention, piloted for 1 year, had 3 components embedded in the electronic health record: assessment of patients' PA, an electronic prompt for providers to counsel patients reporting low PA, and patient monitoring using a Fitbit. Cardiovascular disease risk factors included PA (self-report and Fitbit), body mass index, blood pressure, lipids, and cardiorespiratory fitness assessed with the 6-minute walk test. Depression and quality of life were also assessed. Paired t tests assessed changes in CVD risk. Results The sample who enrolled in the remote patient monitoring (n = 59) were primarily female (51%), White adults (76%) with a mean age of 61.13 ± 11.6 years. Self-reported PA significantly improved over 12 weeks (P =.005), but not Fitbit steps (P =.07). There was a significant improvement in cardiorespiratory fitness (469 ± 108 vs 494 ± 132 m, P =.0034), and 23 participants (42%) improved at least 25 m, signifying a clinically meaningful improvement. Only 4 participants were lost to follow-up over 12 weeks of monitoring. Conclusions Patients may need more frequent reminders to be active after an initial counseling session, perhaps getting automated messages based on their step counts syncing to their electronic health record.

Abstract

This study aimed to examine and compare the associations between education, social media use, and advance care planning (ACP) discussion among Chinese older adults in mainland China (Wuhan), Taiwan (Taichung), and the United States (Honolulu). Community-dwelling older adults (≥ 55) were recruited from 2017 to 2018. The ACP discussion rate in Wuhan, Taichung, and Honolulu were 15.2 %, 19.2 %, and 31.3 %, respectively. Logistic regression models revealed that education was positively associated with ACP discussion in Taichung and Honolulu. Social media use was positively associated with ACP discussions in Wuhan and Honolulu, and it attenuated the association between education and ACP discussion in Honolulu. The present study contributes to previous studies by comparing the associations between education, social media use, and ACP discussion in different settings within the same ethnicity. Policy and practice implications were also discussed.

Abstract

Background: Food insecurity, a pervasive global issue exacerbated by the COVID-19 pandemic, has been linked to adverse mental health outcomes. However, the role of social capital in mitigating this relationship remains understudied, particularly in the Chinese context. Aims: This study investigated the associations between food insecurity and psychological distress (depressive and anxiety symptoms) and examined the potential moderating effects of bonding and bridging social capital among Chinese adults in Shanghai. Methods: This cross-sectional study included 3,220 Chinese adults (mean age: 34.45; 51.5% male) in Shanghai. Food insecurity was assessed using the modified Household Food Insecurity Access Scale, psychological distress was measured using the Patient Health Questionnaire-9 and the Generalized Anxiety Disorder-7, and social capital was evaluated using the Revised Personal Social Capital Scale. Results: Multivariable linear regression analyses revealed that food insecurity was significantly positively associated with both depressive (β = 0.449, SE = 0.024) and anxiety symptoms (β = 0.391, SE = 0.022), after adjusting for sociodemographic characteristics, health status, and COVID-19-related factors. Higher levels of bonding and bridging social capital were significantly associated with fewer depressive and anxiety symptoms. Significant interactions (p <.001) between bonding social capital and food insecurity indicated that the associations between food insecurity and psychological distress were less pronounced among adults with higher bonding social capital. Conclusions: These findings highlight the critical role of food insecurity as a risk factor for psychological distress and the importance of bonding social capital in mitigating its impact on mental health. Policies and interventions targeting food insecurity prevention and bonding social capital enhancement may promote better mental health outcomes among Chinese adults.

Abstract

This paper aims to address the research questions of whether individual’s oral health status is associated with subjective well-being, as well as if there is possible moderating role of self-rated oral health among two groups of Chinese older adults (≥55 years old) in Honolulu, Hawaiʻi and Taichung, Taiwan. Using survey data collected in 2018 (N = 430, Honolulu) and in 2017 (N = 645, Taichung), ordinary least square regressions were applied. Results showed that, for both samples, oral health status was negatively and significantly associated with subjective well-being, and both associations were moderated by self-rated oral health. In addition, the moderating effects were more salient for the Honolulu sample, who enjoyed higher levels of self-rated oral health and life satisfaction. These results suggest the significant associations of both oral health status and self-rated oral health on individual health and well-being for Chinese older adults residing in different cultural contexts.

Abstract

This month we focus on the role of the NICHE Coordinator, who leads NICHE program activities to advance the use of evidence-based practices that improve the quality and safety of care delivered to older adults in healthcare delivery settings. We present a new leadership development class for NICHE Coordinators to enhance their overall effectiveness with implementing the NICHE practice model in their organizations.

Abstract

Background: Aortic Stenosis (AS) is a common syndrome in older adults wherein the narrowing of the aortic valve impedes blood flow, resulting in advanced heart failure.1 AS is associated with a high mortality rate (50 % at 6 months if left untreated), substantial symptom burden, and reduced quality of life.1-3 Transcatheter aortic valve replacement (TAVR) was approved in 2012 as a less invasive alternative to surgical valve repair, offering a treatment for older frail patients. Although objective outcomes have been widely reported,4 the perspectives of older adults undergoing the TAVR process have never been synthesized. Objectives: To contextualize the perspectives and experiences of older adults undergoing TAVR. Methods: An integrative review was conducted using Whittemore and Knafl's five-stage methodology.5 Four electronic databases were searched in April 2023. Articles were included if a qualitative methodology was used to assess the perceptions of older adults (>65 years old) undergoing or recovering from TAVR. Results: Out of 4619 articles screened, 12 articles met the criteria, representing 353 individuals from 10 countries. Relevant themes included the need for an individualized care plan, caregiver and family support, communication and education, persistent psychosocial and physical symptoms, and the unique recovery journey. Conclusion: Older adults with AS undergoing TAVR generally perceive their procedure positively. Improved interdisciplinary and holistic management, open communication, symptom assessment, support, and education is needed.

Abstract

Active service members and Veterans with a combat-related traumatic brain injury (TBI) are four times more likely to attempt suicide than those without a TBI. TBIs are the signature injuries of the Post-9/11 conflicts and Combat Veterans (i.e., current and former service members who deployed in support of a combat mission) with these injuries are entitled to receive the Purple Heart medal. However, potentially tens of thousands of Combat Veterans did not receive, or were denied the Purple Heart during the first decade of the Global War on Terrorism because a TBI was not documented during the deployment. To our knowledge, this is the first study to explore the meaning of the Purple Heart and examine the impact of the Purple Heart on Army Combat Veterans with a combat-related TBI. Findings from this mixed methods study revealed that not receiving the Purple Heart is associated with increased suicide risk and lower quality of life after a brain injury. Additionally, thwarted belongingness, perceived burdensomeness, and perceived military institutional betrayal are associated with increased suicide risk in Army Combat Veterans with a TBI. This mixed methods study provides important insights into how Army culture is perceived and the power of the Purple Heart among this high-risk group of Combat Veterans.

Abstract

To move beyond the focus on individual types of support, we examined the overall reciprocity of support between older adults and their adult children. Drawing on the theory of esteem enhancement, we hypothesized that the under benefited older adults, defined as older adults whose support provided is larger than support received in intergenerational relationships, may have better health conditions than those with a more or less balanced exchange of support. To test the hypothesis, we examined the relationship between the reciprocity of intergenerational support and self-rated health (SRH) among older adults in China. We also investigated the moderating role of gender in this relationship. Using data collected from 832 older adults in Wuhan, China, we found that compared to those with a balanced level of reciprocal support in the intergenerational relationship, older adults who were under benefited from the intergenerational support had better SRH. This finding is in line with the esteem enhancement theory. We also found that gender moderated the association between the reciprocity of intergenerational support and SRH. Specifically, older women who under benefit from the support had better SRH than older women with a balanced level of reciprocal support. In contrast, older men who under benefit from the support had worse SRH than older men with a balanced level of reciprocal support. This finding highlights the necessity of constructing social psychological frameworks that are attuned to gender variations for a more comprehensive comprehension of health and health-related behaviors among older adults in China.

Abstract

Within-host HIV populations continually diversify during untreated infection, and this diversity persists within infected cell reservoirs during antiretroviral therapy (ART). Achieving a better understanding of on-ART proviral evolutionary dynamics, and a better appreciation of how the overall persisting pool of (largely genetically defective) proviruses differs from the much smaller replication-competent HIV reservoir, is critical to HIV cure efforts. We reconstructed within-host HIV evolutionary histories in blood from seven participants of the Women’s Interagency HIV Study who experienced HIV seroconversion, and used these data to characterize the diversity, lineage origins, and ages of proviral env-gp120 sequences sampled longitudinally up to 12 years on ART. We also studied HIV sequences emerging from the reservoir in two participants. We observed that proviral clonality generally increased over time on ART, with clones frequently persisting long term. While on-ART proviral integration dates generally spanned the duration of untreated infection, HIV emerging in plasma was exclusively younger (i.e., dated to the years immediately pre-ART). The genetic and age distributions of distinct proviral sequences remained stable during ART in all but one participant, in whom there was evidence that younger proviruses had been preferentially eliminated after 12 years on ART. Analysis of the gag region in three participants corroborated our env-gp120-based observations, indicating that our observations are not influenced by the HIV region studied. Our results underscore the remarkable genetic stability of the distinct proviral sequences that persist in blood during ART. Our results also suggest that the replication-competent HIV reservoir is a genetically restricted, younger subset of this overall proviral pool. IMPORTANCE Characterizing the genetically diverse HIV sequences that persist in the reservoir despite antiretroviral therapy (ART) is critical to cure efforts. Our observations confirm that proviruses persisting in blood on ART, which are largely genetically defective, broadly reflect the extent of within-host HIV evolution pre-ART. Moreover, on-ART clonal expansion is not appreciably accompanied by the loss of distinct proviral lineages. In fact, on-ART proviral genetic composition remained stable in all but one participant, in whom, after 12 years on ART, proviruses dating to around near ART initiation had been preferentially eliminated. We also identified recombinant proviruses between parental sequence fragments of different ages. Though rare, such sequences suggest that reservoir cells can be superinfected with HIV from another infection era. Overall, our finding that the replication-competent reservoir in blood is a genetically restricted, younger subset of all persisting proviruses suggests that HIV cure strategies will need to eliminate a reservoir that differs in key respects from the overall proviral pool.
