Co-designing care for multimorbidity: a systematic review.

BACKGROUND: The co-design of health care enables patient-centredness by partnering patients, clinicians and other stakeholders together to create services. METHODS: We conducted a systematic review of co-designed health interventions for people living with multimorbidity and assessed (a) their effectiveness in improving health outcomes, (b) the co-design approaches used and (c) barriers and facilitators to the co-design process with people living with multimorbidity. We searched MEDLINE, EMBASE, CINAHL, Scopus and PsycINFO between 2000 and March 2022. Included experimental studies were quality assessed using the Cochrane risk of bias tool (ROB-2 and ROBINS-I). RESULTS: We screened 14,376 reports, with 13 reports meeting the eligibility criteria. Two reported health and well-being outcomes: one randomised clinical trial (n = 134) and one controlled cohort (n = 1933). Outcome measures included quality of life, self-efficacy, well-being, anxiety, depression, functional status, healthcare utilisation and mortality. Outcomes favouring the co-design interventions compared to control were minimal, with only 4 of 17 outcomes considered beneficial. Co-design approaches included needs assessment/ideation (12 of 13), prototype (11 of 13), pilot testing (5 of 13) (i.e. focus on usability) and health and well-being evaluations (2 of 13). Common challenges to the co-design process include poor stakeholder interest, passive participation, power imbalances and a lack of representativeness in the design group. Enablers include flexibility in approach, smaller group work, advocating for stakeholders' views and commitment to the process or decisions made. CONCLUSIONS: In this systematic review of co-design health interventions, we found that few projects assessed health and well-being outcomes, and the observed health and well-being benefits were minimal. The intensity and variability in the co-design approaches were substantial, and challenges were evident. Co-design aided the design of novel services and interventions for those with multimorbidity, improving their relevance, usability and acceptability. However, the clinical benefits of co-designed interventions for those with multimorbidity are unclear.

Post-traumatic stress disorder symptom remission and cognition in a large cohort of civilian women.

BACKGROUND: Post-traumatic stress disorder (PTSD) is associated with cognitive impairments. It is unclear whether problems persist after PTSD symptoms remit. METHODS: Data came from 12 270 trauma-exposed women in the Nurses' Health Study II. Trauma and PTSD symptoms were assessed using validated scales to determine PTSD status as of 2008 (trauma/no PTSD, remitted PTSD, unresolved PTSD) and symptom severity (lifetime and past-month). Starting in 2014, cognitive function was assessed using the Cogstate Brief Battery every 6 or 12 months for up to 24 months. PTSD associations with baseline cognition and longitudinal cognitive changes were estimated by covariate-adjusted linear regression and linear mixed-effects models, respectively. RESULTS: Compared to women with trauma/no PTSD, women with remitted PTSD symptoms had a similar cognitive function at baseline, while women with unresolved PTSD symptoms had worse psychomotor speed/attention and learning/working memory. In women with unresolved PTSD symptoms, past-month PTSD symptom severity was inversely associated with baseline cognition. Over follow-up, both women with remitted and unresolved PTSD symptoms in 2008, especially those with high levels of symptoms, had a faster decline in learning/working memory than women with trauma/no PTSD. In women with remitted PTSD symptoms, higher lifetime PTSD symptom severity was associated with a faster decline in learning/working memory. Results were robust to the adjustment for sociodemographic, biobehavioral, and health factors and were partially attenuated when adjusted for depression. CONCLUSION: Unresolved but not remitted PTSD was associated with worse cognitive function assessed six years later. Accelerated cognitive decline was observed among women with either unresolved or remitted PTSD symptoms.

Salivary inflammatory biomarkers as a predictor of post-traumatic stress disorder and depressive symptom severity in trauma patients: A prospective study.

BACKGROUND: Although post-traumatic stress disorder (PTSD) and depression screening are recommended for traumatic injury patients, routine screening is still uncommon. Salivary inflammatory biomarkers have biological plausibility and potential feasibility and acceptability for screening. This study tested prospective associations between several salivary inflammatory biomarkers (proinflammatory cytokines interleukin-1ß, interleukin-6, tumor necrosis factor-α; and C-reactive protein), collected during hospitalization and PTSD and depressive symptoms at 5-month follow-up. METHODS: Adult traumatic injury patients (N = 696) at a major urban Level 1 trauma center provided salivary samples and completed PTSD and depressive symptom measures during days 0-13 of inpatient hospitalization. At 5-month follow-up, 368 patients (77 % male, 23 % female) completed the Clinician-Administered PTSD Scale for DSM-IV and the Self-rated Inventory of Depressive Symptomatology. Analyses focused on a latent inflammatory cytokine factor and C-reactive protein at baseline predicting 5-month PTSD and depression symptom outcomes and included baseline symptom levels as covariates. RESULTS: A latent factor representing proinflammatory cytokines was not related to 5-month PTSD or depressive symptom severity. Higher salivary CRP was related to greater PTSD symptom severity (ß = .10, p = .03) at 5-month follow-up and more severity in the following depressive symptoms: changes in weight and appetite, bodily complaints, and constipation/diarrhea (ß's from .14 to .16, p's from .004 -.03). CONCLUSION: In a primarily Latine and Black trauma patient sample, salivary CRP measured after traumatic injury was related to greater PTSD symptom severity and severity in several depressive symptom clusters. Our preliminary findings suggest that salivary or systemic CRP may be useful to include in models predicting post-trauma psychopathology.

Migraine headache in patients with spontaneous coronary artery dissection: A report of the iSCAD Registry.

INTRODUCTION: Spontaneous coronary artery dissection (SCAD) is a nonatherosclerotic cause of myocardial infarction. Migraine headache has been reported to be common among patients with SCAD, but the degree of migraine-related disability has not been quantified. METHODS: Clinical data and headache variables were obtained from the baseline assessment of the prospective, multicenter iSCAD Registry. Migraine-related disability was quantified using the self-reported Migraine Disability Assessment (MIDAS). Demographic, clinical, psychosocial, and medical characteristics from data entry forms were compared between patients with and without migraine. RESULTS: Of the 773 patients with available data, 46% reported previous or current migraines. Those with migraines were more likely to be women (96.9% vs 90.3%, p = 0.0003). The presence of underlying carotid fibromuscular dysplasia was associated with migraine (35% vs 27%, p = 0.0175). There was not a significant association with carotid artery dissection and migraine. Current migraine frequency was less than monthly (58%), monthly (24%), weekly (16%), and daily (3%). Triptan use was reported in 32.5% of patients, and 17.5% used daily migraine prophylactic medications. Using the MIDAS to quantify disability related to migraine, 60.2% reported little or no disability, 14.4% mild, 12.7% moderate, and 12.7% severe. The mean MIDAS score was 9.9 (mild to moderate disability). Patients with SCAD had higher rates of depression and anxiety (28.2% vs 17.7% [p = 0.0004] and 35.3% vs 26.7% [p = 0.0099], respectively). CONCLUSIONS: Migraines are common, frequent, and a source of disability in patients with SCAD. The association between female sex, anxiety, and depression may provide some insight for potential treatment modalities.

Through the lens: A qualitative exploration of nurses' experiences of smart glasses in urgent care.

AIM: To investigate the real-world experiences of nurses' using smart glasses to triage patients in an urgent care centre. DESIGN: A parallel convergent mixed-method design. METHODS: We collected data through twelve in-depth interviews with nurses using the device and a survey. Recruitment continued until no new themes emerged. We coded the data using a deductive-thematic approach. Qualitative and survey data were coded and then mapped to the most dominant dimension of the sociotechnical framework. Both the qualitative and quantitative findings were triangulated within each dimension of the framework to gain a comprehensive understanding of user experiences. RESULTS: Overall, nurses were satisfied with using smart glasses in urgent care and would recommend them to others. Nurses rated the device highly on ease of use, facilitation of training and development, nursing empowerment and communication. Qualitatively, nurses generally felt the device improved workflows and saved staff time. Conversely, technological challenges limited its use, and users questioned its sustainability if inadequate staffing could not be resolved. CONCLUSION: Smart glasses enhanced urgent care practices by improving workflows, fostering staff communication, and empowering healthcare professionals, notably providing development opportunities for nurses. While smart glasses offered transformative benefits in the urgent care setting, challenges, including technological constraints and insufficient organisational support, were barriers to sustained integration. IMPLICATIONS FOR PRACTICE: These real-world insights encompass both the benefits and challenges of smart glass utilisation in the context of urgent care. The findings will help inform greater workflow optimisation and future technological developments. Moreover, by sharing these experiences, other healthcare institutions looking to implement smart glass technology can learn from the successes and barriers encountered, facilitating smoother adoption, and maximising the potential benefits for patient care. REPORTING METHOD: COREQ checklist (consolidated criteria for reporting qualitative research). PATIENT OR PUBLIC CONTRIBUTION: No patient or public contribution.

Anhedonic Depression Is Not Associated With Risk of Recurrent Major Adverse Cardiac Events and All-Cause Mortality in Acute Coronary Syndrome Patients.

BACKGROUND: Depression after acute coronary syndrome (ACS) is common and increases risks of adverse outcomes, but it remains unclear which depression features are most associated with major adverse cardiac events (MACE) and all-cause mortality (ACM). PURPOSE: To examine whether a subtype of depression characterized by anhedonia and major depressive disorder (MDD) predicts 1-year MACE/ACM occurrence in ACS patients compared to no MDD history. We also consider other depression features in the literature as predictors. METHODS: Patients (N = 1,087) presenting to a hospital with ACS completed a self-report measure of current depressive symptoms in-hospital and a diagnostic interview assessing MDD within 1 week post-hospitalization. MACE/ACM events were assessed at 1-, 6-, and 12-month follow-ups. Cox regression models were used to examine the association of the anhedonic depression subtype and MDD without anhedonia with time to MACE/ACM, adjusting for sociodemographic and clinical covariates. RESULTS: There were 142 MACE/ACM events over the 12-month follow-up. The 1-year MACE/ACM in patients with anhedonic depression, compared to those with no MDD, was somewhat higher in an age-adjusted model (hazard ratio [HR] = 1.63, p = .08), but was not significant after further covariate adjustment (HR = 1.24, p = .47). Of the additional depression features, moderate-to-severe self-reported depressive symptoms significantly predicted the risk of MACE/ACM, even in covariate-adjusted models (HR = 1.72, p = .04), but the continuous measure of self-reported depressive symptoms did not. CONCLUSION: The anhedonic depression subtype did not uniquely predict MACE/ACM as hypothesized. Moderate-to-severe levels of total self-reported depressive symptoms, however, may be associated with increased MACE/ACM risk, even after accounting for potential sociodemographic and clinical confounders.

Skin Conductance Reactivity as a Predictor of Stroke-induced Posttraumatic Stress Disorder Symptoms: A Dimensional Approach.

Background: Posttraumatic stress disorder (PTSD) symptoms can develop following acute, life-threatening medical events. This study explores a potential biomarker of PTSD risk that is novel to a medical trauma population: a noninvasive, mobile skin conductance (SC) measurement. Methods: Participants (N=64) were enrolled in-hospital following a stroke or transient ischemic attack (TIA). Mobile measurement of SC reactivity to recalling the stroke/TIA traumatic event was conducted at hospital bedside in the days following the stroke/TIA. PTSD symptoms that developed in response to the stroke/TIA were measured at 1-month follow-up. We tested the association between SC reactivity and total 1-month PTSD symptoms, as well as PTSD symptom dimensions of fear and dysphoria. Results: In unadjusted analyses, there were significant positive associations between in-hospital SC reactivity to recalling the stroke/TIA traumatic event and higher-order fear-related symptoms (r=.30, p=.016), as well as lower-order fear-related symptoms of anxious arousal (r=.27, p=.035) and avoidance (r=.25, p=.043) at 1 month. Associations between SC reactivity and the fear, anxious arousal, and avoidance symptom dimensions remained significant in multivariable regression models that adjusted for relevant covariates including age, gender, stroke severity, medical comorbidity, and psychosocial factors. Although there was a positive association observed between SC reactivity to recalling the stroke/TIA event and total PTSD symptom severity at 1-month follow-up, it did not reach the level of statistical significance (r=.23, p=.070). Further, no significant association was detected for dysphoria-related symptoms (r=.11, p=.393). Conclusions: This is the first study to test the prospective association of SC reactivity with PTSD symptom development following a medical trauma. The findings indicate that mobile measures of SC reactivity may be useful for in-hospital identification of individuals at risk for fear-related PTSD symptom development following a medical event and highlight the potential mechanisms involved in the development of these symptoms following a medical event.

Living with COPD: understanding patient experiences through the lens of photovoice.

BACKGROUND: Conventional quantitative or qualitative methodologies may not encompass the wide array of experiences of individuals living with Chronic Obstructive Pulmonary Disease (COPD). We used a novel approach - photovoice-to understand the impact of COPD on activities of daily living (ADLs) in a multicultural Asian country. METHODS: We recruited a purposive sample of eight patients from the outpatient clinics of the National University Health System, Singapore, between December 2020 and August 2021. We adopted a photovoice approach for data collection; participants were invited to take photos of how ADLs were impacted by COPD and attend a follow-up interview. An Interpretative Phenomenological Analysis method was used to analyze the data. Data saturation was reached by the seventh patient. RESULTS: COPD and the resulting breathlessness had a profound and diverse impact on our participants' lives. Living with COPD required substantial changes to how everyday tasks are performed, and participants learnt new strategies to deal with such tasks. A mixture of active and passive coping styles was evident. Feelings of frustration, anxiety and a sense of isolation were also reported. Contextual factors impacting ADLs included challenging climatic conditions and the local popularity of traditional or alternative medicine. CONCLUSION: The photovoice technique improved our understanding of the lived experiences of COPD patients and can benefit those who struggle to articulate their views by offering a different way to communicate beyond conventional interviewing.

Mental health and resilience after the covid-19 pandemic: a multi-ethnic longitudinal survey.

BACKGROUND: Longitudinal work on the impact of COVID-19 on population mental health and resilience beyond the first year of the pandemic is lacking. We aimed to understand how mental health and resilience evolved during the pandemic (2020) and two years later (2022) in a multi-ethnic Singaporean population. In addition, we assessed what characteristics were associated with mental health and resilience scores. METHODS: We surveyed and analysed two balanced panel samples up to four times between 30th April 2020 and 11th July 2022. One panel assessed psychological distress (Kessler-10) and well-being (short Warwick Edinburgh Mental Well-being scale) n = 313, and one panel assessed resilience (10-item Connor-Davidson Resilience Scale©) n = 583. A linear panel regression model with random effects assessed the temporal patterns for psychological distress, well-being, and resilience. RESULTS: Mean psychological distress scores (Kessler-10) were relatively stable over time and were not statistically significantly worse than baseline at any follow-up. Well-being scores improved over time and were significantly better than baseline by the third survey (22nd Jul-18th Aug 2020) (0.54 p = 0.007, Cohen's d 0.12). Scores had worsened by the last survey (27th June-11th July 2022) but were not significantly different from baseline 0.20 p = 0.30. Resilience scores declined over time. Scores at both follow-ups (14th Aug- 4th Sep 2020 and 27th June-11th July 2022) were statistically significantly lower than baseline: -1.69 p < 0.001 (Cohen's d 0.25) and -0.96 p = 0.006 (Cohen's d 0.14), respectively. CONCLUSIONS: Our study joins a body of work measuring the longitudinal effects of COVID-19 on population mental health and resilience. While, the magnitude of the effect related to resilience decline is small, our findings indicate that particular attention should be given to ongoing population surveillance, with the aim of maintaining good health and well-being.

Introduction to the Special Section on the International Society for Traumatic Stress Studies 38th Annual Meeting: Trauma as a transdiagnostic risk factor across the lifespan.

This article serves as an introduction to the special section in the Journal of Traumatic Stress related to the 38th annual meeting of the International Society for Traumatic Stress Studies, held in Atlanta, Georgia (USA) in November 2022. The theme of this meeting, "Trauma as a Transdiagnostic Risk Factor Across the Lifespan," provided an opportunity to recognize the far-reaching impact of trauma and how traumatic experiences can become embedded into the mind, body, and societal spirit. This introductory article outlines the importance of harnessing multiple perspectives to address these wide-ranging sequelae of trauma and provides an overview of the series of contributions to the special section.

Developing an Artificial Intelligence-Driven Nudge Intervention to Improve Medication Adherence: A Human-Centred Design Approach.

To improve medication adherence, we co-developed a digital, artificial intelligence (AI)-driven nudge intervention with stakeholders (patients, providers, and technologists). We used a human-centred design approach to incorporate user needs in creating an AI-driven nudge tool. We report the findings of the first stage of a multi-phase project: understanding user needs and ideating solutions. We interviewed healthcare providers (n = 10) and patients (n = 10). Providers also rated example nudge interventions in a survey. Stakeholders felt the intervention could address existing deficits in medication adherence tracking and were optimistic about the solution. Participants identified flexibility of the intervention, including mode of delivery, intervention intensity, and the ability to stratify to user ability and needs, as critical success factors. Reminder nudges and provision of healthcare worker contact were rated highly by all. Conversely, patients perceived incentive-based nudges poorly. Finally, participants suggested that user burden could be minimised by leveraging existing software (rather than creating a new App) and simplifying or automating the data entry requirements where feasible. Stakeholder interviews generated in-depth data on the perspectives and requirements for the proposed solution. The participatory approach will enable us to incorporate user needs into the design and improve the utility of the intervention. Our findings show that an AI-driven nudge tool is an acceptable and appropriate solution, assuming it is flexible to user requirements.

Trauma, Post-Traumatic Stress Disorder, and Treatment Among Middle-Aged and Older Women in the Nurses' Health Study II.

OBJECTIVE: Trauma and post-traumatic stress disorder (PTSD) are common among women and associated with negative health outcomes across the life course. Relatively few studies, however, have examined the epidemiology of trauma, PTSD, and treatment among middle-aged and older civilian women, who are at elevated risk for adverse health outcomes. We aimed to characterize trauma, PTSD, and trauma-related treatment prevalence and correlates in a large cohort of middle-aged and older women. DESIGN: Cross-sectional, nested substudy within the Nurses' Health Study II cohort. SETTING: United States, 2018-2020. PARTICIPANTS: 33,327 current or former nurses, aged 53-74 years. MEASUREMENTS: 16-item modified version of the Brief Trauma Questionnaire; modified PTSD Checklist for the Diagnostic and Statistical Manual, Version 5. RESULTS: The majority (82.2%) of women reported one or more lifetime traumas. The most common trauma types were unexpected death of a loved one (44.9%) and interpersonal violence (43.5%). Almost 30% reported occupational (nursing-related) trauma. Among the trauma-exposed, 10.5% met criteria for lifetime PTSD and 1.5% had past-month PTSD. One-third of lifetime PTSD cases were due to interpersonal violence event types. One-third of women with lifetime PTSD-and nearly half of those with PTSD from a nursing-related trauma-reported never receiving trauma-related treatment. Women aged 65 years and older with PTSD were less likely to be in treatment than those aged less than 65 years. CONCLUSION: History of trauma and PTSD is prevalent in this population, and a treatment gap persists. Addressing this treatment gap is warranted, particularly among older women and those with nursing-related trauma.

The association of posttraumatic stress disorder, depression, and head injury with mid-life cognitive function in civilian women.

BACKGROUND: Despite evidence linking posttraumatic stress disorder (PTSD), depression, and head injury, separately, with worse cognitive performance, investigations of their combined effects on cognition are limited in civilian women. METHODS: The Cogstate Brief Battery assessment was administered in 10,681 women from the Nurses' Health Study II cohort, mean age 64.9 years (SD = 4.6). Psychological trauma, PTSD, depression, and head injury were assessed using online questionnaires. In this cross-sectional analysis, we used linear regression models to estimate mean differences in cognition by PTSD/depression status and stratified by history of head injury. RESULTS: History of head injury was prevalent (36%), and significantly more prevalent among women with PTSD and depression (57% of women with PTSD and depression, 21% of women with no psychological trauma or depression). Compared to having no psychological trauma or depression, having combined PTSD and depression was associated with worse performance on psychomotor speed/attention ( ß = -.15, p = .001) and learning/working memory ( ß = -.15, p < .001). The joint association of PTSD and depression on worse cognitive function was strongest among women with past head injury, particularly among those with multiple head injuries. CONCLUSIONS: Head injury, like PTSD and depression, was highly prevalent in this sample of civilian women. In combination, these factors were associated with poorer performance on cognitive tasks, a possible marker of future cognitive health. Head injury should be further explored in future studies of PTSD, depression and cognition in women.

Continuing chronic care services during a pandemic: results of a mixed-method study.

BACKGROUND: Patients with chronic diseases have seen unprecedented changes to healthcare practices since the emergence of COVID-19. Traditional 'on-site' clinics have had to innovate to continue services. Whether these changes are acceptable to patients and are effective for care continuation are largely unreported. METHODS: We evaluated the effectiveness of care provision at a re-structured chronic care clinic and elicited the patient experiences of care and self-management. We conducted a convergent, parallel, mixed-methods study. Adult patients attending a chronic care clinic were included. We extracted data from 4,849 clinic visits before and during the COVID-19 pandemic, including operational metrics and attendee profile. We also conducted fifteen interviews with patients from the same clinic using a semi-structured interview guide. RESULTS: Re-structuring the chronic clinic, including the introduction of teleconsultations, home-delivery of prescriptions and use of community-based phlebotomy services, served to maintain continuity of care while adhering to COVID-19 containment measures. Qualitatively, five themes emerged. Patients were able to adjust to healthcare practice changes and adapt their own lifestyles, although poor self-management practices were adopted. While most were apprehensive about attending the clinic, they valued ongoing care access and were reassured by the on-site containment measures. CONCLUSIONS: Continuation of routine services is desired by patients and can be achieved through the adoption of containment measures, by greater collaboration with community partners, and the use of technology. Patients adapted to service changes, but poor self-management was evident. To prevent chronic disease relapse, services must strive to innovate rather than suspend services during pandemics.

Posttraumatic Stress Disorder (PTSD) as a Risk Factor for Cardiovascular Disease: Implications for Future Research and Clinical Care.

PURPOSE OF REVIEW: Posttraumatic stress disorder (PTSD) may be an important risk factor for cardiovascular disease (CVD). We explore the literature linking PTSD to CVD, potential mechanisms, interventions, and clinical implications. We outline gaps in current literature and highlight necessary future research. RECENT FINDINGS: PTSD has been independently associated with deleterious effects on cardiovascular health through biological, behavioral, and societal pathways. There are evidence-based psychotherapeutic interventions and pharmacotherapies for PTSD that may mitigate its impact on CVD. However, there are limited studies that rigorously analyze the impact of treating PTSD on cardiovascular outcomes. Trauma-informed CVD risk stratification, education, and treatment offer opportunities to improve patient care. These approaches can include a brief validated screening tool for PTSD identification and treatment. Pragmatic trials are needed to test PTSD interventions among people with CVD and evaluate for improved outcomes.

Back to the Hospital for Chronic Care: a Hybrid Generalist Model.

Singapore, like many countries, is attempting to meet the growing healthcare needs of an ageing population with a high burden of chronic diseases. Despite efforts to integrate and increase healthcare capacity, longstanding challenges remain difficult to overcome. Recently, policymakers have considered a new approach to building chronic and eldercare capacity-the Integrated General Hospital (IGH). The development of the IGH model is motivated by a combination of factors: the limit to which the primary care system can manage patients with increasingly complex chronic diseases, a longstanding preference of patients for hospital-based specialty services and patients experiencing fragmented care delivery. The IGH model links hospital care teams and community-based care providers, to facilitate the management of patients throughout the care continuum in a single integrated site. It is hoped that this hospital-led model for chronic care can meet patients' needs and preferences and reduce fragmentation of care.

Posttraumatic stress disorder and changes in diet quality over 20 years among US women.

BACKGROUND: Individuals with posttraumatic stress disorder (PTSD) are at increased risk of various chronic diseases. One hypothesized pathway is via changes in diet quality. This study evaluated whether PTSD was associated with deterioration in diet quality over time. METHODS: Data were from 51 965 women in the Nurses' Health Study II PTSD sub-study followed over 20 years. Diet, assessed at 4-year intervals, was characterized via the Alternative Healthy Eating Index-2010 (AHEI). Based on information from the Brief Trauma Questionnaire and Short Screening Scale for DSM-IV PTSD, trauma/PTSD status was classified as no trauma exposure, prevalent exposure (trauma/PTSD onset before study entry), or new-onset (trauma/PTSD onset during follow-up). We further categorized women with prevalent exposure as having trauma with no PTSD symptoms, trauma with low PTSD symptoms, and trauma with high PTSD symptoms, and created similar categories for women with new-onset exposure, resulting in seven comparison groups. Multivariable linear mixed-effects spline models tested differences in diet quality changes by trauma/PTSD status over follow-up. RESULTS: Overall, diet quality improved over time regardless of PTSD status. In age-adjusted models, compared to those with no trauma, women with prevalent high PTSD and women with new-onset high PTSD symptoms had 3.3% and 3.6% lower improvement in diet quality, respectively, during follow-up. Associations remained consistent after adjusting for health conditions, sociodemographics, and behavioral characteristics. CONCLUSIONS: PTSD is associated with less healthy changes in overall diet quality over time. Poor diet quality may be one pathway linking PTSD with a higher risk of chronic disease development.

Not all posttraumatic stress disorder symptoms are equal: fear, dysphoria, and risk of developing hypertension in trauma-exposed women.

BACKGROUND: Posttraumatic stress disorder (PTSD) is associated with higher risk of incident hypertension, but it is unclear whether specific aspects of PTSD are particularly cardiotoxic. PTSD is a heterogeneous disorder, comprising dimensions of fear and dysphoria. Because elevated fear after trauma may promote autonomic nervous system dysregulation, we hypothesized fear would predict hypertension onset, and associations with hypertension would be stronger with fear than dysphoria. METHODS: We examined fear and dysphoria symptom dimensions in relation to incident hypertension over 24 years in 2709 trauma-exposed women in the Nurses' Health Study II. Posttraumatic fear and dysphoria symptom scores were derived from a PTSD diagnostic interview. We used proportional hazards models to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) for each symptom dimension (quintiles) with new-onset hypertension events (N = 925), using separate models. We also considered lower-order symptom dimensions of fear and dysphoria. RESULTS: Higher levels of fear (P-trend = 0.02), but not dysphoria (P-trend = 0.22), symptoms were significantly associated with increased hypertension risk after adjusting for socio-demographics and family history of hypertension. Women in the highest v. lowest fear quintile had a 26% higher rate of developing hypertension [HR = 1.26 (95% CI 1.02-1.57)]; the increased incidence associated with greater fear was similar when further adjusted for biomedical and health behavior covariates (P-trend = 0.04) and dysphoria symptoms (P-trend = 0.04). Lower-order symptom dimension analyses provided preliminary evidence that the re-experiencing and avoidance components of fear were particularly associated with hypertension. CONCLUSIONS: Fear symptoms associated with PTSD may be a critical driver of elevated cardiovascular risk in trauma-exposed individuals.

Earlier age at menarche as a transdiagnostic mechanism linking childhood trauma with multiple forms of psychopathology in adolescent girls.

BACKGROUND: Although early life adversity (ELA) increases risk for psychopathology, mechanisms linking ELA with the onset of psychopathology remain poorly understood. Conceptual models have argued that ELA accelerates development. It is unknown whether all forms of ELA are associated with accelerated development or whether early maturation is a potential mechanism linking ELA with psychopathology. We examine whether two distinct dimensions of ELA - threat and deprivation - have differential associations with pubertal timing in girls, and evaluate whether accelerated pubertal timing is a mechanism linking ELA with the onset of adolescent psychopathology. METHODS: Data were drawn from a large, nationally representative sample of 4937 adolescent girls. Multiple forms of ELA characterized by threat and deprivation were assessed along with age at menarche (AAM) and the onset of DSM-IV fear, distress, externalizing, and eating disorders. RESULTS: Greater exposure to threat was associated with earlier AAM (B = -0.1, p = 0.001). Each 1-year increase in AAM was associated with reduced odds of fear, distress, and externalizing disorders post-menarche (ORs = 0.74-0.85). Earlier AAM significantly mediated the association between exposure to threat and post-menarche onset of distress (proportion mediated = 6.2%), fear (proportion mediated = 16.3%), and externalizing disorders (proportion mediated = 2.9%). CONCLUSIONS: Accelerated pubertal development in girls may be one transdiagnostic pathway through which threat-related experiences confer risk for the adolescent onset of mental disorders. Early pubertal maturation is a marker that could be used in both medical and mental health settings to identify trauma-exposed youth that are at risk for developing a mental disorder during adolescence in order to better target early interventions.

Hyperarousal Symptoms in Survivors of Cardiac Arrest Are Associated With 13 Month Risk of Major Adverse Cardiovascular Events and All-Cause Mortality.

BACKGROUND: Key dimensions of cardiac arrest-induced posttraumatic stress disorder (PTSD) symptoms include reexperiencing, avoidance, numbing, and hyperarousal. It remains unknown which dimensions are most predictive of outcome. PURPOSE: To determine which dimensions of cardiac arrest-induced PTSD are predictive of clinical outcome within 13 months posthospital discharge. METHODS: PTSD symptoms were assessed in survivors of cardiac arrest who were able to complete psychological screening measures at hospital discharge via the PTSD Checklist-Specific scale, which queries for 17 symptoms using five levels of severity. Responses on items for each symptom dimension of the four-factor numbing model (reexperiencing, avoidance, numbing, and hyperarousal) were converted to Z-scores and treated as continuous predictors. The combined primary endpoint was all-cause mortality (ACM) or major adverse cardiovascular events (MACE; hospitalization for myocardial infarction, unstable angina, heart failure, emergency coronary revascularization, or urgent defibrillator/pacemaker placements) within 13 months postdischarge. Four bivariate Cox proportional hazards survival models evaluated associations between individual symptom dimensions and ACM/MACE. A multivariable model then evaluated whether significant bivariate predictors remained independent predictors of the primary outcome after adjusting for age, sex, comorbidities, premorbid psychiatric diagnoses, and initial cardiac rhythm. RESULTS: A total of 114 patients (59.6% men, 52.6% white, mean age: 54.6 ± 13 years) were included. In bivariate analyses, only hyperarousal was significantly associated with ACM/MACE. In a fully adjusted model, 1 standard deviation increase in hyperarousal symptoms corresponded to a two-times increased risk of experiencing ACM/MACE. CONCLUSIONS: Greater level of hyperarousal symptoms was associated with a higher risk of ACM/MACE within 13 months postcardiac arrest. This initial evidence should be further investigated in a larger sample.
