Qi, X., Ng, T. K. S., & Wu, B. (2023). Psychoneuroendocrinology, 149. 10.1016/j.psyneuen.2023.106023
Abstract
Abstract
Background: Previous research has reported the association between social isolation and cognitive impairment. However, biological mechanisms underlying this association are understudied. It is also unclear whether there are sex differences in these biological mechanisms. Objectives: To examine whether chronic inflammation biomarkers are potential mediators of the association between social isolation and cognitive functioning among older men and women. Methods: Data were the National Health and Nutrition Examination Survey 1999–2002. A total of 2535 older adults aged 60 and older were included. Chronic inflammation was measured by C-reactive protein (CRP), plasma fibrinogen, and serum albumin. Cognitive functioning was assessed by the Digit Symbol Substitution Test (DSST). Social isolation was defined using a 4-point composite index of items pertaining to the strength of social network and support. Linear regression models and formal mediation analysis were applied. Results: Social isolation was associated with lower DSST scores [β (SE) = −2.445 (1.180), p < 0.01 for men; β (SE) = −5.478 (1.167), p < 0.001 for women]. For older men, social isolation was associated with higher levels of CRP (β [SE] = 0.226 (0.110), p < 0.05) and fibrinogen (β [SE] = 0.058 (0.026), p < 0.05). In mediation analyses, among older men, CRP mediated 6.1% and fibrinogen mediated 12.0% of the association of social isolation with DSST. Conclusion: Social isolation was associated with poorer cognitive functioning partially via heightened inflammatory responses in older men. Defining these associations’ mechanisms in sex-specific contexts could inform preventive and therapeutic strategies for cognitive impairment in older adults.

Sleep Variability, Eating Timing Variability, and Carotid Intima-Media Thickness in Early Adulthood

Hoopes, E. K., Witman, M. A., D’Agata, M. N., Brewer, B., Edwards, D. G., Robson, S. M., Malone, S. K., Keiser, T., & Patterson, F. (2023). Journal of the American Heart Association, 12(19). 10.1161/JAHA.123.029662
Abstract
Abstract
BACKGROUND: Day-to-day variability in sleep patterns and eating timing may disrupt circadian rhythms and has been linked with various adverse cardiometabolic outcomes. However, the extent to which variability in sleep patterns and eating timing relate to atherosclerotic development in subclinical stages remains unclear. METHODS AND RESULTS: Generally healthy adults (N=62, 29.3±7.3 years, 66% female) completed 14 days of sleep and dietary assessments via wrist accelerometry and photo-assisted diet records, respectively. Variability in sleep duration, sleep onset, eating onset (time of first caloric consumption), eating offset (time of last caloric consumption), and caloric midpoint (time at which 50% of total daily calories are consumed) were operationalized as the SD across 14 days for each variable. Separate regression models evaluated the cross-sectional associations between sleep and eating variability metrics with end-diastolic carotid intima-media thickness (CIMT) measured via ultrasonography. Models adjusted for age, sex, systolic blood pressure, sleep duration, and total energy intake. Each 60-minute increase in sleep duration SD and sleep onset SD were associated with a 0.049±0.016 mm (P=0.003) and 0.048±0.017 mm (P=0.007) greater CIMT, respectively. Variability in eating onset and offset were not associated with CIMT; however, each 60-minute increase in caloric midpoint SD was associated with a 0.033±0.015 mm greater CIMT (P=0.029). Exploratory post hoc analyses suggested that sleep duration SD and sleep onset SD were stronger correlates of CIMT than caloric midpoint SD. CONCLUSIONS: Variability in sleep patterns and eating timing are positively associated with clinically relevant increases in CIMT, a biomarker of subclinical atherosclerosis, in early adulthood.

Social isolation, loneliness and accelerated tooth loss among Chinese older adults: A longitudinal study

Qi, X., Pei, Y., Wang, K., Han, S., & Wu, B. (2023). Community Dentistry and Oral Epidemiology, 51(2), 201-210. 10.1111/cdoe.12727
Abstract
Abstract
Objective: Social isolation and loneliness have been linked to numerous determinants of health and well-being. However, the effects of social isolation and loneliness on oral health remain unclear. The purpose of this study was to examine the effects of social isolation and loneliness on the number of remaining teeth and the rate of tooth loss over time among Chinese older adults. Methods: We used three waves of data (2011/2012, 2014 and 2018) from the Chinese Longitudinal Healthy Longevity Survey with 4268 older adults aged 65 and older who were interviewed in at least two waves. The number of remaining teeth was first evaluated at baseline and then subsequently at follow-up visits. Mixed-effects Poisson regression was used to examine the associations between social isolation, loneliness, and both the number of remaining teeth and the rate of tooth loss. Results: Social isolation was associated with fewer remaining teeth (β = −.06, 95% CI = −0.13 to 0.00, p <.05) and accelerated tooth loss (β = −.02, 95% CI = −0.02 to −0.01, p <.01) after adjusting for sociodemographic covariates, lifestyle and oral hygiene behaviours, physical and cognitive health, and loneliness. Loneliness was neither associated with the number of remaining teeth (β =.15, 95% CI = −0.01 to 0.30, p =.06) nor with the rate of tooth loss (β = −.01, 95% CI = −0.02 to 0.00, p =.16) after adjusting for all other factors. Conclusions: This study provides strong evidence that social isolation was associated with fewer remaining teeth and accelerated tooth loss among Chinese older adults. These findings expand our knowledge about the impact of social disconnection on tooth loss. More future studies are needed to further examine the associations between social connections and oral conditions using longitudinal cohort studies and intervention studies.

Social Isolation, Sleep Disturbance, and Cognitive Functioning (HRS): A Longitudinal Mediation Study

Qi, X., Pei, Y., Malone, S. K., & Wu, B. (2023). The Journals of Gerontology. Series A, Biological Sciences and Medical Sciences, 78(10), 1826-1833. 10.1093/gerona/glad004
Abstract
Abstract
BACKGROUND: Social isolation is prevalent and associated with dementia, yet the directionality and mechanisms are less understood. This study examined the association between social isolation and cognitive functioning and explored the mediating role of sleep disturbance on the social isolation-cognition relationship. METHODS: Data from 5 753 dementia-free Americans aged ≥50 of 2006 (T1), 2010 (T2), and 2014 (T3) waves of the Health and Retirement Study. Social isolation was measured by the Steptoe Social Isolation Index. Cognitive functioning was measured by the Telephone Interview of Cognitive Status. Sleep disturbance was measured with the modified Jenkins Sleep Scale. We used cross-lagged panel models to determine the associations between social isolation, sleep disturbance, and cognitive functioning. RESULTS: Social isolation is significantly associated with subsequent cognitive functioning (T1 to T2: β = -0.055, standard error [SE] = 0.014, p < .001; T2 to T3: β = -0.044, SE = 0.016, p < .001). Lower cognitive functioning is significantly associated with greater subsequent social isolation (T1 to T2: β = -0.101, SE = 0.020, p < .001; T2 to T3: β = -0.058, SE = .011, p < .001). Sleep disturbance at T2 partially mediated the effect of social isolation (T1) on cognitive functioning (T3), accounting for 6.2% of the total effect (β = -0.003, SE = 0.001, p < .01). CONCLUSIONS: Social isolation may deteriorate cognitive functioning and vice versa. The association between social isolation and cognition is partially explained by sleep disturbance.

Sources of stress and coping mechanisms: Experiences of maternal health care providers in Western Kenya

Getahun, M., Oboke, E. N., Ogolla, B. A., Kinyua, J., Ongeri, L., Sterling, M., Oluoch, I., Lyndon, A., & Afulani, P. A. (2023). PLOS Global Public Health, 3(2), e0001341. 10.1371/journal.pgph.0001341
Abstract
Abstract
The dynamic and complex nature of care provision predisposes healthcare workers to stress, including physical, emotional, or psychological fatigue due to individual, interpersonal, or organizational factors. We conducted a convergent mixed-methods study with maternity providers to understand their sources of stress and coping mechanisms they adopt. Data were collected in Migori County in western Kenya utilizing quantitative surveys with n = 101 maternity providers and in-depth interviews with a subset of n = 31 providers. We conducted descriptive analyses for the quantitative data. For qualitative data, we conducted thematic analysis, where codes were deductively developed from interview guides, iteratively refined based on emergent data, and applied by a team of five researchers using Dedoose software. Code queries were then analysed to identify themes and organized using the socioecological (SE) framework to present findings at the individual, interpersonal, and organizational levels. Providers reported stress due to high workloads (61%); lack of supplies (37%), poor salary (32%), attitudes of colleagues and superiors (25%), attitudes of patients (21%), and adverse outcomes (16%). Themes from the qualitative analysis mirrored the quantitative analysis with more detailed information on the factors contributing to each and how these sources of stress affect providers and patient outcomes. Coping mechanisms adopted by providers are captured under three themes: addressing stress by oneself, reaching out to others, and seeking help from a higher power. Findings underscore the need to address organizational, interpersonal, and individual level stressors. Strategies are needed to support staff retention, provide adequate resources and incentives for providers, and ultimately improve patient outcomes. Interventions should support and leverage the positive coping mechanisms identified.

Study Protocol Using Cohort Data and Latent Variable Modeling to Guide Sampling Women with Type 2 Diabetes and Depressive Symptoms

Perez, N. B., D’Eramo Melkus, G., Yu, G., Brown-Friday, J., Anastos, K., & Aouizerat, B. (2023). Nursing Research, 72(5), 409-415. 10.1097/NNR.0000000000000669
Abstract
Abstract
Background Depression affects one in three women with Type 2 diabetes, and this concurrence significantly increases the risks of diabetes complications, disability, and early mortality. Depression is underrecognized because of wide variation in presentation and the lack of diagnostic biomarkers. Converging evidence suggests inflammation is a shared biological pathway in diabetes and depression. Overlapping epigenetic associations and social determinants of diabetes and depression implicate inflammatory pathways as a common thread. Objectives This article describes the protocol and methods for a pilot study aimed to examine associations between depressive symptoms, inflammation, and social determinants of health among women with Type 2 diabetes. Methods This is an observational correlational study that leverages existing longitudinal data from the Women's Interagency HIV Study (WIHS), a multicenter cohort of HIV seropositive (66%) and HIV seronegative (33%) women, to inform purposive sampling of members from latent subgroups emergent from a prior retrospective cohort-wide analysis. Local active cohort participants from the Bronx study site are then selected for the study. The WIHS recently merged with the Multicenter Aids Cohort Study (MACS) to form the MACS/WIHS Combined Cohort Study. Latent subgroups represent distinct symptom trajectories resultant from a growth mixture model analysis of biannually collected depressive symptom data. Participants complete surveys (symptom and social determinants) and provide blood samples to analyze plasma levels and DNA methylation of genes that encode for inflammatory markers (CRP, IL-6, TNF-). Correlation and regression analysis will be used to estimate the effect sizes between depressive symptoms and inflammatory markers, clinical indices (body mass index, hemoglobin A1C, comorbidities), and social determinants of health. Results The study began in January 2022, and completed data collection is estimated by early 2023. We hypothesize that depressive symptom severity will associate with higher levels of inflammation, clinical indices (e.g., higher hemoglobin A1C), and exposure to specific social determinants of health (e.g., lower income, nutritional insecurity). Discussion Study findings will provide the basis for future studies aimed at improving outcomes for women with Type 2 diabetes by informing the development and testing of precision health strategies to address and prevent depression in populations most at risk.

Systematic review of transcriptome and microRNAome associations with gestational diabetes mellitus

Lewis, K. A., Chang, L., Cheung, J., Aouizerat, B. E., Jelliffe-Pawlowski, L. L., McLemore, M. R., Piening, B., Rand, L., Ryckman, K. K., & Flowers, E. (2023). Frontiers in Endocrinology, 13. 10.3389/fendo.2022.971354
Abstract
Abstract
Purpose: Gestational diabetes (GDM) is associated with increased risk for preterm birth and related complications for both the pregnant person and newborn. Changes in gene expression have the potential to characterize complex interactions between genetic and behavioral/environmental risk factors for GDM. Our goal was to summarize the state of the science about changes in gene expression and GDM. Design: The systematic review was conducted using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Methods: PubMed articles about humans, in English, from any date were included if they described mRNA transcriptome or microRNA findings from blood samples in adults with GDM compared with adults without GDM. Results: Sixteen articles were found representing 1355 adults (n=674 with GDM, n=681 controls) from 12 countries. Three studies reported transcriptome results and thirteen reported microRNA findings. Identified pathways described various aspects of diabetes pathogenesis, including glucose and insulin signaling, regulation, and transport; natural killer cell mediated cytotoxicity; and fatty acid biosynthesis and metabolism. Studies described 135 unique miRNAs that were associated with GDM, of which eight (miR-16-5p, miR-17-5p, miR-20a-5p, miR-29a-3p, miR-195-5p, miR-222-3p, miR-210-3p, and miR-342-3p) were described in 2 or more studies. Findings suggest that miRNA levels vary based on the time in pregnancy when GDM develops, the time point at which they were measured, sex assigned at birth of the offspring, and both the pre-pregnancy and gestational body mass index of the pregnant person. Conclusions: The mRNA, miRNA, gene targets, and pathways identified in this review contribute to our understanding of GDM pathogenesis; however, further research is warranted to validate previous findings. In particular, longitudinal repeated-measures designs are needed that control for participant characteristics (e.g., weight), use standardized data collection methods and analysis tools, and are sufficiently powered to detect differences between subgroups. Findings may be used to improve early diagnosis, prevention, medication choice and/or clinical treatment of patients with GDM.

Technology-Based Interventions to Address Social Isolation and Loneliness Among Informal Dementia Caregivers: A Scoping Review

Mao, W., Qi, X., Chi, I., Wichinsky, L., & Wu, B. (2023). Journal of the American Medical Directors Association, 24(11), 1700-1707. 10.1016/j.jamda.2023.08.005
Abstract
Abstract
Objective: Social isolation and loneliness are major public health concerns. Informal dementia caregivers are particularly vulnerable, as many are older adults themselves and at elevated risk of adverse mental and physical health outcomes. Technology-based interventions could offer accessible, affordable, and convenient solutions. A previous review included Internet-based supportive interventions for informal dementia caregivers published up to 2013; however, new publications, technological advances, and targeted outcomes justify conducting this scoping review. Here, we identified and synthesized recent technology-based interventions that addressed social isolation and loneliness among informal dementia caregivers. Design: Scoping review. Setting and Participants: Informal dementia caregivers in the community. Methods: Following Arksey and O'Malley's scoping review framework, we conducted a systematic search of peer-reviewed studies across 6 databases within the last 11 years, including identifying research questions, selecting relevant studies, charting data, and summarizing results. Results: From the 2937 articles identified, 10 eligible studies were included in this review. The intervention type, format, and duration varied widely. Three categories of interventions to address social isolation and loneliness among informal dementia caregivers included technology-assisted peer support, newly developed Web-based multicomponent psychoeducational programs and platforms, and virtual adaptation and modification of existing programs. Predominantly qualitative evidence suggests that technology-based interventions have the potential to reduce feelings of loneliness and improve caregiver well-being. Quantitative evidence tends to be preliminary and inconclusive. Conclusions and Implications: The findings offer preliminary evidence for technology-based interventions to reduce or prevent social isolation and loneliness in informal dementia caregivers. Technology-based interventions addressing social isolation and loneliness in informal dementia caregivers have the potential to overcome barriers to low uptake of services and withdrawal from interventions and improve the sustainability of the interventions. In the long run, by reducing or preventing social isolation and loneliness in informal dementia caregivers, the transition from home care to facility-based care might be delayed.

Telehealth Policy and the Advanced Practice Nurse

Garber, K., Chike-Harris, K., Vetter, M. J., Kobeissi, M., Heidesch, T., Arends, R., Teall, A. M., & Rutledge, C. (2023). Journal for Nurse Practitioners, 19(7). 10.1016/j.nurpra.2023.104655
Abstract
Abstract
Telehealth is an efficient and effective method of care delivery used by advance practice registered nurses (APRNs) nationally, especially in the wake of the coronavirus disease 2019 pandemic. With the ever-changing rules and regulations governing telehealth practice, the APRN may struggle to keep abreast. Telehealth is governed by legislation and regulation in addition to telehealth-specific laws. APRNs delivering care through telehealth must be informed about the crucial aspects of telehealth policy and how their practice is affected. Telehealth-related policy is complex and evolving and varies by state. This article provides APRNs with essential knowledge about telehealth-related policy to support legal and regulatory compliance.

Temporal associations between nightly sleep with daytime eating and activity levels in free-living young adults

Hoopes, E. K., Brewer, B., Robson, S. M., Witman, M. A., D’Agata, M. N., Malone, S. K., Edwards, D. G., & Patterson, F. (2023). Sleep, 46(11). 10.1093/sleep/zsad123
Abstract
Abstract
Study Objectives: This study aimed to quantify the temporal associations between nightly sleep quantity and timing with daytime eating behavior and activity levels in free-living (i.e. non-experimental) settings. Methods: Generally healthy young adults (N = 63; 28.9 ± 7.1 years) completed concurrent sleep (wrist actigraphy), eating (photo-assisted diet records), and activity (waist actigraphy) assessments over 14 days. Multilevel models quantified the associations between nightly sleep (total sleep time, timing of sleep and wake onset) with next-day eating behavior (diet quality, caloric intake, timing of eating onset/offset, eating window duration) and activity levels (total physical activity, sedentary time). Associations in the reverse direction (i.e. eating and activity predicting sleep) were explored. Models adjusted for demographic and behavioral confounders and accounted for multiple testing. Results: At within- and between-subject levels, nights with greater-than-average total sleep time predicted a shorter eating window the next day (all p ≤ 0.002). Later-than-average sleep and wake timing predicted within- and between-subject delays in next-day eating onset and offset, and between-subject reductions in diet quality and caloric intake (all p ≤ 0.008). At within- and between-subject levels, total sleep time was bidirectionally, inversely associated with sedentary time (all p < 0.001), while later-than-average sleep and wake timing predicted lower next-day physical activity (all p ≤ 0.008). Conclusions: These data underscore the complex interrelatedness between sleep, eating behavior, and activity levels in free-living settings. Findings also suggest that sleep exerts a greater influence on next-day behavior, rather than vice versa. While testing in more diverse samples is needed, these data have potential to enhance health behavior interventions and maximize health outcomes.

Time, Technology, Social Support, and Cardiovascular Health of Emerging Adults With Type 1 Diabetes

McCarthy, M., Yan, J., Jared, M. C., Ilkowitz, J., Gallagher, M. P., & Dickson, V. V. (2023). Nursing Research, 72(3), 185-192. 10.1097/NNR.0000000000000645
Abstract
Abstract
BACKGROUND: Emerging adults with Type 1 diabetes (T1DM) face an increased risk of cardiovascular disease; however, there are both barriers and facilitators to achieving ideal cardiovascular health in this stage of their lives. OBJECTIVES: The aim of this study was to qualitatively explore the barriers and facilitators of achieving ideal levels of cardiovascular health in a sample of emerging adults with T1DM ages 18-26 years. METHODS: A sequential mixed-methods design was used to explore achievement of ideal cardiovascular health using the seven factors defined by the American Heart Association (smoking status, body mass index, physical activity, healthy diet, total cholesterol, blood pressure, and hemoglobin A1C [substituted for fasting blood glucose]). We assessed the frequency of achieving ideal levels of each cardiovascular health factor. Using Pender's health promotion model as a framework, qualitative interviews explored the barriers and facilitators of achieving ideal levels of each factor of cardiovascular health. RESULTS: The sample was mostly female. Their age range was 18-26 years, with a diabetes duration between 1 and 20 years. The three factors that had the lowest achievement were a healthy diet, physical activity at recommended levels, and hemoglobin A1C of <7%. Participants described lack of time as a barrier to eating healthy, being physically active, and maintaining in-range blood glucose levels. Facilitators included the use of technology in helping to achieve in-range blood glucose and social support from family, friends, and healthcare providers in maintaining several healthy habits. DISCUSSION: These qualitative data provide insight into how emerging adults attempt to manage their T1DM and cardiovascular health. Healthcare providers have an important role in supporting these patients in establishing ideal cardiovascular health at an early age.

Tooth Loss, Periodontal Disease, and Mild Cognitive Impairment Among Hispanic/Latino Immigrants: The Moderating Effects of Age at Immigration

Luo, H., Wu, B., González, H. M., Stickel, A., Kaste, L. M., Tarraf, W., Daviglus, M. L., Sanders, A. E., & Cai, J. (2023). The Journals of Gerontology. Series A, Biological Sciences and Medical Sciences, 78(6), 949-957. 10.1093/gerona/glac178
Abstract
Abstract
BACKGROUND: The objectives were to assess (a) the association between poor oral health and mild cognitive impairment (MCI) in Hispanic/Latino immigrants and (b) potential modification effects on this association by age at immigration. METHODS: Data were from the Hispanic Community Health Study/Study of Latinos and its ancillary study-the Study of Latinos-Investigation of Neurocognitive Aging. MCI, a binary outcome variable, defined by the National Institute on Aging-Alzheimer's Association criteria. The main exposure was significant tooth loss (STL), defined as a loss of 8 or more teeth, and periodontitis, classified using the Centers for Disease Control and Prevention and American Academy of Periodontology case classification. Multiple logistic regression was used to assess the association between STL/periodontitis and MCI and test moderation effects of age at immigration. The analytical sample comprised 5 709 Hispanic/Latino adult immigrants. RESULTS: Hispanic/Latino immigrants with STL (adjusted odds ratio [AOR] = 1.36, 95% confidence interval [CI]: 1.01-1.85) were more likely to have MCI than those with greater tooth retention. Overall, migration to the United States after age 18 was associated with greater odds of MCI than migration at a younger age. A significant interaction effect between STL and age at immigration revealed that the effect of STL on MCI is even higher in those who immigrated to the United States at ages 35-49 years. CONCLUSIONS: STL is a significant risk factor for MCI and age at immigration had a modification effect on the association between STL and MCI. Better access to dental care, health education on risk factors of MCI, and promotion of good oral health may mitigate the burden of cognitive impairment in Hispanics/Latinos.

Trauma Considerations

Merlo, G., & Sugden, S. G. (2023). In Lifestyle Psychiatry (1–, pp. 63-70). CRC Press. 10.1201/b22810-6
Abstract
Abstract
Trauma is a complex phenomenon that has varying degrees of intensity and impairment for individuals who experience it. As a result, many develop chronic behavioral and physical health sequela that increase their interactions within the healthcare system. The chronicity of these symptoms is further complicated by their overarching adoption of shame, as an unintended chronic coping skill. Shame becomes a master or blanket emotion that suppresses other healthier emotions and healthy interactions with others and the individual’s community. As the majority of individuals have had traumatic exposures, it is hard for healthcare providers to know on the onset which of their patients experience ongoing sequela or not. Subsequently, unintended interactions with the healthcare system have worsened the trauma-related symptoms for many. Over the years, healthcare providers have been encouraged to adopt universal precautions for all blood-borne encounters. Similarly, healthcare providers are encouraged to implement trauma-informed care, universally, to all patients as a means to create healthier environments for healing.

Trends and Disparities in Severe Maternal Morbidity Indicator Categories During Childbirth Hospitalization in California from 1997-2017

El Ayadi, A. M., Lyndon, A., Kan, P., Mujahid, M. S., Leonard, S. A., Main, E. K., & Carmichael, S. (2023). American Journal of Perinatology. 10.1055/a-2223-3520
Abstract
Abstract
Objective Severe maternal morbidity (SMM) is increasing and characterized by substantial racial and ethnic disparities. Analyzing trends and disparities across time by etiologic or organ system groups instead of an aggregated index may inform specific, actionable pathways to equitable care. We explored trends and racial and ethnic disparities in seven SMM categories at childbirth hospitalization. Study Design We analyzed California birth cohort data on all live and stillbirths ≥20 weeks gestation from 1997-2017 (n=10,580,096) using the Centers for Disease Control and Prevention's SMM index. Cases were categorized into seven non-mutually exclusive indicator categories (cardiac, renal, respiratory, hemorrhage, sepsis, other obstetric, and other medical SMM). We compared prevalence and trends in SMM indicator categories overall and by racial and ethnic group using logistic and linear regression. Results SMM occurred in 1.16% of births and non-transfusion SMM in 0.54%. Hemorrhage SMM occurred most frequently (27 per 10,000 births), followed by other obstetric (11), respiratory (7), and sepsis, cardiac, and renal SMM (5). Hemorrhage, renal, respiratory, and sepsis SMM increased over time for all racial and ethnic groups. The largest disparities were for Black individuals, including over three-fold increased odds of other medical SMM. Renal and sepsis morbidity had the largest relative increases over time (717% and 544%). Sepsis and hemorrhage SMM had the largest absolute changes over time (17 per 10,000 increase). Disparities increased over time for respiratory SMM among Black, US-born Hispanic, and non-US-born Hispanic individuals and for sepsis SMM among Asian or Pacific Islander individuals. Disparities decreased over time for sepsis SMM among Black individuals yet remained substantial. Conclusion Our research further supports the critical need to address SMM and disparities as a significant public health priority in the United States and suggests that examining SMM subgroups may reveal helpful nuance for understanding trends, disparities and potential needs for intervention.

Trends in the survival benefit of repeat kidney transplantation over the past 3 decades

Sandal, S., Ahn, J. Y. B., Chen, Y., Massie, A. B., Clark-Cutaia, M. N., Wu, W., Cantarovich, M., Segev, D. L., & McAdams-DeMarco, M. A. (2023). American Journal of Transplantation, 23(5), 666-672. 10.1016/j.ajt.2023.01.008
Abstract
Abstract
Repeat kidney transplantation (re-KT) is the preferred treatment for patients with graft failure. Changing allocation policies, widening the risk profile of recipients, and improving dialysis care may have altered the survival benefit of a re-KT. We characterized trends in re-KT survival benefit over 3 decades and tested whether it differed by age, race/ethnicity, sex, and panel reactive assay (PRA). By using the Scientific Registry of Transplant Recipient data, we identified 25 419 patients who underwent a re-KT from 1990 to 2019 and 25 419 waitlisted counterfactuals from the same year with the same waitlisted time following graft failure. In the adjusted analysis, a re-KT was associated with a lower risk of death (adjusted hazard ratio [aHR] = 0.63; 95% confidence interval [CI], 0.61-0.65). By using the 1990-1994 era as a reference (aHR = 0.77; 95% CI, 0.69-0.85), incremental improvements in the survival benefit were noted (1995-1999: aHR = 0.72; 95% CI, 0.67-0.78: 2000-2004: aHR = 0.59; 95% CI, 0.55-0.63: 2005-2009: aHR = 0.59; 95% CI, 0.56-0.63: 2010-2014: aHR = 0.57; 95% CI, 0.53-0.62: 2015-2019: aHR = 0.64; 95% CI, 0.57-0.73). The survival benefit of a re-KT was noted in both younger (age = 18-64 years: aHR = 0.63; 95% CI, 0.61-0.65) and older patients (age ≥65 years: aHR = 0.66; 95% CI, 0.58-0.74; Pinteraction = .45). Patients of all races/ethnicities demonstrated similar benefits with a re-KT. However, it varied by the sex of the recipient (female patients: aHR = 0.60; 95% CI, 0.56-0.63: male patients: aHR = 0.66; 95% CI, 0.63-0.68; Pinteraction = .004) and PRA (0-20: aHR = 0.69; 95% CI, 0.65-0.74: 21-80: aHR = 0.61; 95% CI, 0.57-0.66; Pinteraction = .02; >80: aHR = 0.57; 95% CI, 0.53-0.61; Pinteraction< .001). Our findings support the continued practice of a re-KT and efforts to overcome the medical, immunologic, and surgical challenges of a re-KT.

Trends in U.S. HIV Peer Health Worker Training Strategies and Approaches: A Scoping Review of the Literature

Gormley, M., Loughran, C., Conte, J., & Dunn Navarra, A. M. (2023). Journal of the Association of Nurses in AIDS Care, 34(4), 331-348. 10.1097/JNC.0000000000000415
Abstract
Abstract
Peer health workers (peers) are commonly engaged interventionists in the HIV care spectrum. The objective of this scoping review was to examine the range of evidence on training strategies and approaches for peer-led HIV behavioral interventions in the United States. Four electronic databases (Medline, CINAHL, EMBASE, and PsycINFO) were searched for peer-reviewed published literature (2010-2021) of peer-led HIV behavioral interventions directed to improving antiretroviral therapy adherence and/or retention in care. Eighteen studies met the inclusion criteria. Eleven studies referenced manualized training materials, and nine used role-play as part of their curricula. Peer training content and duration varied across studies, as well as evaluation of intervention fidelity, and peer competency. Findings highlight heterogeneity in peer training strategies and approaches. The expansion and sustainability of peer engagement in the HIV care continuum will require greater consensus among members of the research community on best practices for training.

Unraveling the central and bridge psychological symptoms of people living with HIV: A network analysis

Wen, H., Zhu, Z., Hu, T., Li, C., Jiang, T., Li, L., Zhang, L., Fu, Y., Han, S., Wu, B., & Hu, Y. (2023). Frontiers in Public Health, 10. 10.3389/fpubh.2022.1024436
Abstract
Abstract
Background: People living with HIV (PLWH) experience multiple psychological symptoms. Few studies have provided information on central and bridge psychological symptoms among PLWH. This information has implications for improving the efficiency and efficacy of psychological interventions. Our study aimed to identify the central and bridge psychological symptoms of PLWH and to explore the interconnectedness among symptoms and clusters. Methods: Our study used data from the HIV-related Symptoms Monitoring Survey, a multisite, cross-sectional study conducted during 2017–2021. We used R to visualize the network of 16 symptoms and analyzed the centrality and predictability indices of the network. We further analyzed the bridge symptoms among the three symptom clusters. Results: A total of 3,985 participants were included in the analysis. The results suggested that sadness had the highest strength (rS = 9.69) and predictability (70.7%) compared to other symptoms. Based on the values of bridge strength, feeling unsafe (rbs = 0.94), uncontrollable worry (rbs = 0.82), and self-abasement (rbs = 0.81) were identified as bridge symptoms. We also found a strong correlation between sadness and self-abasement (r = 0.753) and self-loathing and self-blame (r = 0.744). Conclusion: We found that sadness was the central psychological symptom of PLWH, indicating that sadness was the center of the psychological symptom network from a mechanistic perspective and could be a target for intervention. Deactivating bridge symptoms, including “feeling unsafe,” “self-abasement,” and “uncontrollable worry,” could be more effective in preventing symptom activation from spreading (e.g., one symptom activating another).

Use of Galactagogues to Increase Milk Production Among Breastfeeding Mothers in the United States: A Descriptive Study

Ryan, R. A., Hepworth, A. D., Lyndon, A., & Bihuniak, J. D. (2023). Journal of the Academy of Nutrition and Dietetics, 123(9), 1329-1339. 10.1016/j.jand.2023.05.019
Abstract
Abstract
Background: Perceived insufficient milk is a primary reason for early breastfeeding cessation. Some breastfeeding mothers may use galactagogues (ie, foods, beverages, herbal supplements, and pharmaceuticals) to try to increase milk supply. However, milk production requires frequent and effective milk removal, and there is limited evidence on the safety and efficacy of galactagogues. Additional research on the use of galactagogues is needed to inform breastfeeding support. Objective: Describe the prevalence of use and perceived effects of galactagogues and compare galactagogue use by maternal characteristics. Design: Cross-sectional online survey. Participants/setting: A convenience sample of 1,294 adult women breastfeeding a singleton child and living in the United States were recruited using paid Facebook advertisements between December 2020 and February 2021. Main outcome measures: Self-reported current or previous use of galactagogues and their perceived effects on milk production. Statistical analyses performed: Frequencies and percentages described the use and perceived effects of galactagogues. The χ2 test of independence and independent t tests compared galactagogue use by select maternal characteristics. Results: More than half of participants (57.5%) reported using any galactagogues, 55.4% reported consuming foods or beverages, and 27.7% reported using herbal supplements. Few participants (1.4%) reported using pharmaceuticals. Participants reported varying effects of specific galactagogues on milk production. Reported galactagogue use was higher among participants who reported first-time breastfeeding (yes: 66.7% vs no: 49.3%; P < 0.001), breastfeeding pumped milk (yes: 63.1% vs no: 50.4%; P < 0.001), formula supplementation (yes: 66.8% vs no: 50.4%; P < 0.001), and perceived insufficient milk (yes: 78.8% vs no: 53.8%; P < 0.001). Conclusions: Breastfeeding mothers in the United States commonly reported using galactagogues to increase milk production, highlighting the need for research on the safety and efficacy of galactagogues and enhanced breastfeeding support.

Park, J. H., Rada, L., Feder, S. L., Montano, A. R., Batten, J., Tan, H., Grey, M., & Schulman-Green, D. (2023). Nursing Outlook, 71(1). 10.1016/j.outlook.2022.10.003
Abstract
Abstract
Background: The Self- and Family Management Framework (SFMF) identifies factors and outcomes of patient and family management of chronic illness. In a previous citation analysis, we reported the frequency and nature of use of the SFMF. Purpose: We conducted a sub-analysis of quantitative articles in the citation analysis to examine testing of relationships depicted in the SFMF. Methods: We analyzed study purposes, independent and dependent variables, study implications, and text that referred to the SFMF in 40 articles. Findings: The SFMF has been used largely to explore factors affecting SFM behaviors, focusing on patient versus family self-management. Independent variables included all categories of facilitators/barriers specified in the SFMF. Dependent variables included all SFMF components (Facilitators/Barriers, Processes, Proximal and Distal Outcomes). Racial/ethnic diversity was limited among study participants. Study implications pertained mostly to psychosocial outcomes. Most studies referred to the SFMF generally. Discussion: Findings will contribute to revision of the SFMF.

Using Design Thinking to Thread the Social Determinants of Health in an Undergraduate Curriculum

Ea, E., Vetter, M. J., & Boyar, K. (2023). Nurse Educator, 48(2), 114-115. 10.1097/NNE.0000000000001293
Abstract
Abstract
The Future of Nursing Report 2020-20301 calls for nursing education to integrate the social determinants of health (SDoH) in the curriculum to prepare future nurses to take an active role in identifying and addressing health inequities. Nurse faculty and schools of nursing face multiple challenges that pose as barriers to meet this demand. These challenges include a crowded curriculum, lack of a coherent curricular framework, and a dearth of evidence-based teaching strategies to ensure that concepts on SDoH, health equity, and social justice are seamlessly integrated in the nursing curriculum.

Using medical expenditure panel survey data to explore the relationship between patient-centered medical homes and racial disparities in severe maternal morbidity outcomes

Tucker, C. M., Bell, N., Corbett, C. F., Lyndon, A., & Felder, T. M. (2023). Women’s Health, 19. 10.1177/17455057221147380
Abstract
Abstract
Background: There are persistent racial/ethnic disparities in the occurrence of severe maternal morbidity. Patient-centered medical home care has the potential to address disparities in maternal outcomes. Objectives: To examine (1) the association between receiving patient-centered medical home care and severe maternal morbidity outcomes and (2) the interaction of race/ethnicity on patient-centered medical home status and severe maternal morbidity. Design/Methods: Using 2007 to 2016 data from the Medical Expenditures Panel Survey, we conducted a cross-sectional study to estimate the association between receipt of care from a patient-centered medical home and the occurrence of severe maternal morbidity, and racial-specific (White, Black, Asian, Other) relative risks of severe maternal morbidity. Our study used race as a proxy measure for exposure racism. We identified mothers (⩾15 years) who gave birth during the study period. We identified patient-centered medical home qualities using 11 Medical Expenditures Panel Survey questions and severe maternal morbidities using medical claims, and calculated generalized estimating equation models to estimate odds ratios of severe maternal morbidity and 95% confidence intervals. Results: Among all mothers who gave birth (N = 2801; representing 5,362,782 US lives), only 25% received some exposure patient-centered medical home care. Two percent experienced severe maternal morbidity, and this did not differ statistically (p = 0.11) by patient-centered medical home status. However, our findings suggest a 85% decrease in the risk of severe maternal morbidity among mothers who were defined as always attending a patient-centered medical home (odds ratios: 0.15; 95% confidence interval:0.01–1.87; p = 0.14) and no difference in the risk of severe maternal morbidity among mothers who were defined as sometimes attending a patient-centered medical home (odds ratios: 1.00; 95% confidence interval:0.16–6.42; p = 1.00). There was no overall interaction effect in the model between race and patient-centered medical home groups (p = 0.82), or ethnicity and patient-centered medical home groups (p = 0.62) on the severe maternal morbidity outcome. Conclusion: While the rate of severe maternal morbidity was similar to US rates, few mothers received care from a patient-centered medical home which may be due to underreporting. Future research should further investigate the potential for patient-centered medical home-based care to reduce odds of severe maternal morbidity across racial/ethnic groups.

Using meta-research to foster diverse, equitable, and inclusive collaborative research networks

Stevens, E. R., Brody, A. A., Epps, F., Sloan, D. H., & Sherman, S. E. (2023). Journal of the American Geriatrics Society, 71(4), 1028-1033. 10.1111/jgs.18217
Abstract
Abstract
Fostering diverse, equitable, and inclusive collaborative research networks is important for advancing the field of aging research. Despite sizeable investment in research consortia and career development programs, there has been only moderate progress toward diversifying the research workforce studying aging. Without critically examining what works and what does not, continuing to place more resources into these same strategies may not result in a substantial improvement in diversity or the creation of collaborative networks. Using meta-research to rigorously evaluate potential strategies to promote diversity and collaboration may yield important insights that can be used to improve upon current efforts. For this reason, we sought to describe meta-research and highlight how its principles can be used to achieve the aging research community's collaboration and diversity goals.
