Measures Of Anxiety Research Articles

Validity and reliability of an Arabic-language version of the postpartum specific anxiety scale research short-form in Jordan.

The English-language Postpartum Specific Anxiety Scale (PSAS) is a valid, reliable measure for postpartum anxiety (PPA), but its 51-item length is a limitation. Consequently, the PSAS Working Group developed the PSAS Research Short-Form (PSAS-RSF), a statistically robust 16-item tool that effectively assesses PPA. This study aimed to assess and validate the reliability of an Arabic-language version of the PSAS-RSF in Jordan (PSAS-JO-RSF). Using a cross-sectional methodological design, a sample of Arabic-speaking mothers (N = 391) with infants aged up to 6 months were recruited via convenience sampling from a prominent tertiary hospital in northern Jordan. Factor analysis, composite reliability (CR), average variance extracted (AVE), McDonald's ω, and inter-item correlation measures were all examined. Explanatory factor analysis revealed a four-factor model consistent with the English-language version of the PSAS-RSF, explaining a cumulative variance of 61.5%. Confirmatory factor analysis confirmed the good fit of the PSAS-JO-RSF (χ2/df = 1.48, CFI = 0.974, TLI = 0.968, RMSEA = 0.039, SRMR = 0.019, p < 0.001). The four factors demonstrated acceptable to good reliability, with McDonald's ω ranging from 0.778 to 0.805, with 0.702 for the overall scale. The CR and AVE results supported the validity and reliability of the PSAS-JO-RSF. This study establishes an Arabic-language version of the PSAS-JO-RSF as a valid and reliable scale for screening postpartum anxieties in Jordan.

Brief Meditation on Test Anxiety of Eighth Grade Chinese Students: Chain-Mediating Roles of Mindfulness and Self-Efficacy

Numerous studies have revealed an alarming prevalence of test anxiety among Chinese junior high school students. Prevention of test anxiety in this population has become crucial. Brief meditation intervention (BMI) has shown promising results for promoting students’ well-being and reducing test anxiety, but its mechanism for reducing test anxiety remains unknown. This study examined the effects of BMI and the roles mindfulness and self-efficacy play in mediating between the intervention and test anxiety. The BMI was optimized in content and form and culturally tailored for Chinese eighth graders. It includes guided meditation with relaxation music, mindful breathing and body scanning, and positive suggestions that promote self-efficacy. Six eighth grade classes at an urban junior high school in Beijing (N = 202, Mage = 14.14, 102 males) were assigned to either a BMI group (3 classes, N = 103) or a control group (3 classes, N = 99). Test anxiety, mindfulness, and self-efficacy measures were administered before, in the middle of, immediately after, and one month after the intervention. Repeated measures ANOVA and mediation analysis indicated that BMI had a significant effect on reducing test anxiety and enhancing mindfulness and self-efficacy over time. The study also found that mindfulness and self-efficacy played a chain of mediating roles in the relationship between BMI and test anxiety. The mediation effect value accounted for 68.35% of the intervention effects.

Correlations of Physical and Psychological Health in Parents of Individuals With Autism Spectrum Disorder.

Individuals with autism spectrum disorder (ASD) have social communication difficulties and restricted, repetitive, and/or sensory behaviors or interests. The prevalence of ASD is now 1 in 36 individuals. Parents of individuals with ASD face challenges that can affect their physical and psychological well-being. With the long-term goal to tailor an exercise program, the purpose of this study was 2-fold: (1) establish the baseline physical and mental health of parents of individuals with ASD and (2) estimate the relationship of physiologic variables with psychological variables of health for parents of individuals with ASD. This descriptive, cross-sectional study (N = 44) explored physical health measures and the correlation between physical and psychological health, using measures of anxiety, stress, parenting depression, and positive thinking for parents who care for individuals with ASD. The common characteristics that these parents shared was high body fat and low physical activity. Body fat was negatively correlated to total step count (r = -0.428, P < .05), grip strength (r = -0.319, P < .5), and total distance walked in the week (r = -0.661, P < .01), and positively correlated to 5-times sit to stand (r = 0.337, P < .05). Low activity correlated to increased parenting stress of advocating for child's needs (r = -0.310, P = .043). Understanding relationships between physical and psychological health informs effective interventions and support systems for parents. Parents need supports to be able to prioritize exercise. Future studies should include a larger sample to verify these effects.

Is political anxiety different than general anxiety?

Recently, there has been growing interest in the concept of political anxiety. One important question that remains unanswered is whether political anxiety is just a symptom of general anxiety-that those reporting anxiety tied to politics are the same individuals who would already score highly on measures of general anxiety. Using survey data collected in 2023 (N = 436), we find that measures of political and generalized anxiety do not appear to be tapping into a single underlying construct. In addition, the systematic correlates of these measures identified by previous literature are not equivalent predictors of the different types of anxiety. Politics seems to be a source of apprehensiveness and worry that affects individuals who are not necessarily suffering from general anxiety.

Concentrated transdiagnostic and cross-disciplinary micro-choice based group treatment for patients with depression and with anxiety leads to lasting improvements after 12 months: a pilot study

BackgroundA concentrated transdiagnostic and micro choice-based group treatment for patients with depression and anxiety has previously shown to yield significant reduction in symptoms and increased level of functioning from pre to 3-month follow-up. In the present study, we report the results after 12 months follow-up.MethodsThis was a non-randomized clinical intervention pilot study, conducted in line with a published protocol. Sixty-seven consecutively referred patients, aged 19–47 (mean age 32.5, SD = 8.0) were included and completed treatment. All had a severity of their problems that entitled them to care in the specialist public mental health care. Self-reported age at onset of symptoms was 17.6 (SD = 7.9) years. Mean number of prior treatment courses was 3.5 (SD = 3.3; range 0–20). The main objective was to assess the treatment effectiveness by questionnaires measuring relevant symptoms at pre-treatment, 7 days-, 3 months-, 6 months- and at 12-months follow-up.ResultsValidated measures of functional impairment (WSAS), depression (PHQ9), anxiety (GAD7), worry (PSWQ), fatigue (CFQ), insomnia (BIS) and illness perception (BIPQ) improved significantly (p < .0005) from before treatment to 12 months follow-up, yielding mostly large to extremely large effect sizes (0.89–3.68), whereas some moderate (0.60–0.76). After 12 months, 74% report an overall improvement in problems related to anxiety and depression. Utilization of specialist, public and private mental health care was reported as nonexistent or had decreased for 70% of the patients at 12-month follow up.ConclusionsThe concentrated, micro-choice based group treatment approach yielded a highly clinically significant reduction in a wide range of symptoms already one week after treatment, and the positive results persisted at 12-month follow-up.Trial registrationClinicalTrials.gov Identifier: NCT05234281, first posted date 10/02/2022.

Group-Based Acceptance and Commitment Therapy for PTSD in a HMO Psychiatry Clinic: An Open Trial

Mindfulness and acceptance-based approaches have shown promise as alternative interventions to trauma-focused therapies for PTSD. This open trial examined the potential effectiveness of an 8-session Acceptance and Commitment Therapy (ACT) group in reducing psychiatric symptoms and improving quality of life in outpatient adults (N = 86, 79% female) receiving treatment for PTSD in a health maintenance organization (HMO) psychiatry clinic. The group therapy was an adjunct to usual care and utilized the six core processes of ACT: acceptance, cognitive defusion, mindfulness, self-as-context, values, and committed action. Participants completed self-report measures of PTSD symptoms, depression, anxiety and quality of life; and self-report ACT-specific process measures of acceptance, cognitive defusion and mindfulness at pretreatment, posttreatment and 3-month follow-up. Repeated measures analyses of variance conducted with a completer sample (n = 55) demonstrated significant improvements on all variables with medium to large effect sizes at posttreatment and follow-up. The study findings support further investigation in a randomized controlled trial.

The Relationship between Coping Strategies and State Anxiety during COVID-19 Lockdown: The Role of Perceived Emotional Intelligence

Background: The outbreak of the COVID-19 pandemic has caused an unprecedented and unexpected change all around the globe. The long-term effects are still ongoing, especially those related to the confinement measures. The study took place during the first COVID-19 lockdown in Italy, where everyone was forced to stay home in order to reduce the spread of the virus. The aim was to investigate the role of perceived emotional intelligence abilities (PEI) in coping with COVID-19-related anxiety. Methods: A cross-sectional study design was employed, and this study used an online survey launched through social networks, inviting adults to participate. The participants anonymously completed a three-scale online measurement of self-reported emotional abilities, coping strategies (approach and avoidance), and state anxiety towards COVID-19. Results: perceived emotional intelligence and approach coping significantly predicted state anxiety. In addition, perceived emotional intelligence mediated the relationship between approach coping and state anxiety. Conclusions: the study highlights the positive role of perceived emotional abilities in dealing with the unprecedented event represented by the COVID-19 pandemic, and in particular, in coping with anxiety related to lockdown and confinement. Their results highlight the importance of fostering emotional intelligence for navigating critical life events.

Diagnostic accuracy and clinical utility of the PHQ-2 and GAD-2: a comparison with long-format measures for depression and anxiety.

Anxiety and depression are highly prevalent and often comorbid mental disorders that are encompassed within the broad category of emotional disorders. The frequent comorbidity of anxiety and depression can pose challenges for accurate diagnosis and treatment which, in turn, highlights the need for reliable measurements that are simultaneously responsive to change and prevent non-response bias. Brief measures of anxiety and depression can potentially increase response rates due to their brevity and ease of administration. This study evaluates the psychometric characteristics, discriminative accuracy, and sensitivity to change of the Generalized Anxiety Disorder 2-item scale (GAD-2) and the Patient Health Questionnaire 2-item scale (PHQ-2) within a clinical population. The sample comprised treatment-seeking participants (n = 3,411), screened (n = 2,477) to receive an internet-based psychotherapeutic intervention (cognitive-behavioral, psychodynamic, or waitlist). Brief measures can effectively detect individuals who may be eligible for a diagnosis of depression and anxiety, not only prior to but also during and following the completion of psychological treatment. The discriminative ability of the GAD-2 was significantly greater during active treatment and at post-assessment compared with pre-treatment screening, although no such differences were found for the PHQ-2. Finally, endorsing the most severe response option on the GAD-2 and PHQ-2 was associated with a high probability of presenting with clinically relevant anxiety and depressive symptoms. Brief measures of anxiety and depression are viable instruments to screen for and monitor anxiety and depressive symptoms. ClinicalTrials.gov, identifier NCT05016843.

Clinical effectiveness of drop-in mental health services at paediatric hospitals: A non-randomised multi-site study for children and young people and their families - study protocol.

Despite the high prevalence of mental health difficulties in children and young people with long-term health conditions (LTCs), these difficulties and experiences are often overlooked and untreated. Previous research demonstrated the effectiveness of psychological support provided via a drop-in mental health centre located in a paediatric hospital. The aim of this prospective non-randomised single-arm multi-centre interventional study is to determine the clinical effectiveness of drop-in mental health services when implemented at paediatric hospitals in England. It is hypothesised that families who receive psychological interventions through the drop-in services will show improved emotional and behavioural symptoms. Outcomes will be measured at baseline and at 6-month follow-up. The primary outcome is the difference in the total difficulties score on the Strengths and Difficulties Questionnaire (SDQ) reported by parent or child at 6 months. Secondary outcomes include self and parent reported Paediatric Quality of Life Inventory (PedsQL), self-reported depression (PHQ-9) and anxiety measures (GAD-7) and family satisfaction (CSQ-8). This trial aims to determine the clinical effectiveness of providing psychological support in the context of LTCs through drop-in mental health services at paediatric hospitals in England. These findings will contribute to policies and practice addressing mental health needs in children and young people with other long-term health conditions.

Factor Structure of the Experiences in Close Relationships-Relationship Structures Scale (ECR-RS) in Siblings of Children with Chronic Disorders.

Our objective was to examine the factor structure of the Experiences in Close Relationships-Relationships Structures (ECR-RS), an attachment-theory based relationship measure, in at-risk sample comprising siblings of children with chronic disorders. Psychometric studies with general populations have demonstrated that the ECR-RS comprises two factors, representing anxiety and avoidance in close relationships. The sample comprised 103 siblings (M age = 11.5 years, SD = 2.2, range 8 to 16 years) of children with chronic disorders and their parents. The siblings completed a 9-item version of the Experiences in Close Relationships-Relationships Structures (ECR-RS) about their relations with mothers and fathers that was analyzed with confirmatory factor analysis. We examined construct validity using correlations between sibling social functioning, measured with the Strengths and Difficulties Questionnaire, and parent mental health, measured with the Hopkins Symptom Checklist-90-Revised. The ECR-RS comprised two factors, anxiety and avoidance, in line with previous studies. Both factors demonstrated significant overlap with sibling social functioning, but not with parental mental health. We conclude that the ECR-RS comprises two factors, anxiety and avoidance, that are related to siblings' social functioning. The ECR-RS can be used as a psychometrically sound measure of relationship anxiety and avoidance in families of children with chronic disorders.

The impact of the Systematic Assessment for Resilience (SAR) framework on students’ resilience, anxiety, depression, burnout, and academic-related stress: a quasi-experimental study

BackgroundMedical students face significant psychological stress, impacting their academic performance and well-being. The Systematic Assessment for Resilience (SAR) framework is designed to enhance resilience and mitigate stress among medical students, addressing the need for interventions within the assessment system in medical education. The aim of this study was to evaluate the implementation of SAR framework on medical students’ resilience, anxiety, depression, burnout, and academic stress.MethodsThis study employed a quasi-experimental design with pre- and post-testing. It involved the training of course coordinators in implementing the SAR framework and its integration into the daily learning activities. Fourth-year medical students were assessed before and after the intervention using standardized measures of resilience, anxiety, depression, burnout, and academic stress. Data were analyzed using quantitative methods and thematic analysis for qualitative feedback.ResultsPost-intervention, students demonstrated a significant increase in resilience scores (p < 0.001) and a notable decrease in measures of anxiety, depression, and academic stress (p < 0.001). The burnout types were also statistically different (p < 0.001) except client-related burnout (p > 0.05). Qualitative feedback of the course coordinators highlighted an improved learning environment, increased coping strategies, and a more supportive academic culture.ConclusionThe SAR framework significantly contributes to enhancing medical students’ resilience and reducing psychological distress. Its implementation suggests a promising approach to fostering a supportive educational environment that not only addresses the psychological challenges faced by medical students but also enhances their academic performance and overall well-being. Further research is warranted to explore the long-term impacts of SAR across different medical education contexts.

Efficacy of a transdiagnostic internet-based program for adolescents with emotional disorders: A randomized controlled trial

ObjectiveThe Unified Protocol for Transdiagnostic Treatment of Emotional Disorders in Adolescents (UP-A) is a well-established transdiagnostic cognitive-behavioral therapy (T-CBT) intervention. The aim of the present study was to examine the efficacy of the program Learn to Manage your Emotions [Aprende a Manejar tus Emociones] (AMtE), a self-applied transdiagnostic internet-delivered program based on the Spanish version of the UP-A. This is the first transdiagnostic internet-based program designed for the treatment of emotional disorders in adolescents. MethodA sample of Spanish adolescents with a primary diagnosis of an anxiety and/or depressive disorder (n = 58; age range = 12–18 years; 78.3% girls; 90% Caucasian) were randomly allocated to receive AMtE (n = 28) or the UP-A via videocall (n = 30). Pre-treatment, post-treatment and 3-month follow-up data were collected using self-reports and clinician-rated measures of anxiety, depression, positive and negative affect, anxiety sensitivity and emotional avoidance. ResultsBased on generalized estimating equations (GEE) models, both intervention programs were effective in significantly reducing self-reported anxiety and depressive disorder symptoms and clinician-rated severity of anxiety and depression, as well as self-reported transdiagnostic outcome variables. ConclusionsData provide empirical support for the efficacy of AMtE as a transdiagnostic online CBT treatment for anxiety and depressive disorders in adolescents. No marked nor consistent differences were observed between the UP-A and AMtE, highlighting the potential usefulness of the online self-administered AMtE program.

Polygenic liability for anxiety in association with comorbid anxiety in multiple sclerosis.

Comorbid anxiety occurs often in MS and is associated with disability progression. Polygenic scores offer a possible means of anxiety risk prediction but often have not been validated outside the original discovery population. We aimed to investigate the association between the Generalized Anxiety Disorder 2-item scale polygenic score with anxiety in MS. Using a case-control design, participants from Canadian, UK Biobank, and United States cohorts were grouped into cases (MS/comorbid anxiety) or controls (MS/no anxiety, anxiety/no immune disease or healthy). We used multiple anxiety measures: current symptoms, lifetime interview-diagnosed, and lifetime self-report physician-diagnosed. The polygenic score was computed for current anxiety symptoms using summary statistics from a previous genome-wide association study and was tested using regression. A total of 71,343 individuals of European genetic ancestry were used: Canada (n = 334; 212 MS), UK Biobank (n = 70,431; 1,390 MS), and the USA (n = 578 MS). Meta-analyses identified that in MS, each 1-SD increase in the polygenic score was associated with ~50% increased odds of comorbid moderate anxious symptoms compared to those with less than moderate anxious symptoms (OR: 1.47, 95% CI: 1.09-1.99). We found a similar direction of effects in the other measures. MS had a similar anxiety genetic burden compared to people with anxiety as the index disease. Higher genetic burden for anxiety was associated with significantly increased odds of moderate anxious symptoms in MS of European genetic ancestry which did not differ from those with anxiety and no comorbid immune disease. This study suggests a genetic basis for anxiety in MS.

Metacognitive therapy versus exposure and response prevention for obsessive-compulsive disorder – A non-inferiority randomized controlled trial

ObjectiveExposure with response prevention (ERP) is the first-line treatment for obsessive-compulsive disorder (OCD). However, refusals, dropouts and the required high time and logistic effort constitute barriers to the use of ERP. In a non-inferiority randomized controlled trial, we compared metacognitive therapy (MCT) to exposure with response prevention (ERP) as treatments for OCD. Method74 outpatients received 12 weekly sessions of either manualized MCT or ERP, with primary outcomes assessed by blinded assessors using the Yale-Brown Obsessive Compulsive Scale (Y-BOCS) at pre-treatment, mid-treatment, post-treatment, and 6-month follow-up. Secondary outcomes included measures of depression and anxiety. Non-inferiority margin was specified at no less than d = 0.38 below the improvement reached by ERP, corresponding to a difference of about 3 points on the Y-BOCS. ResultsDrop-out rates were low (<14%) and similar in both groups. Linear models indicated non-inferiority of MCT to ERP at post-treatment, but not at 6-month follow-up. While both groups showed comparable Y-BOCS improvements, the MCT group demonstrated a significantly greater reduction in state anxiety scores at post-treatment and follow-up. ConclusionsOverall, MCT was not inferior to ERP, especially at post-treatment, suggesting it could be a treatment alternative. However, further research is needed to explore differential treatment indications.

Effectiveness of Trained Community Lay Workers on Glycemic Control, Knowledge, and Self-Efficacy Among Agricultural Workers with Diabetes in the Texas Panhandle

Systemic health barriers, economic challenges, and lack of follow-up care exacerbate self-management of chronic diseases like diabetes among Hispanic agricultural workers. The primary objective of this pilot project was to determine the benefit of using community coaches to decrease A1C levels and increase diabetes knowledge among agricultural workers with diagnosed diabetes in the Texas Panhandle. A longitudinal study design with two phases was used to create, deliver, and evaluate a diabetes coaching program. Phase 1 was the development of the program and community coaches training (n = 4). In Phase 2, the coaches then delivered the program over 12 weeks to thirteen clients. Phase 1: All coaches were Hispanic females, 28.3 (SD 3.8) years of age, half had at most a high school education level and the other half had a vocational certification (n = 4). Mean DKQ-24 score was 54.2% (SD = 29.7) at baseline and 75.0% (SD = 31.4) after training (t (4) = 4.6, P < 0.05). We observed a very large difference between mean baseline and exit DKQ-24 scores relative to the pooled standard deviation, resulting in an effect size estimate of 0.59 indicative of a medium to large learning effect. Phase 2: Clients were Hispanic Spanish-speaking, predominantly female (55%), 44.4 (SD 6.8) years of age with at most a high school level of education (88.9%) and occupations varied from dairy farm worker (33.3%), meat processing worker (33.3%), and other agriculture or manufacturing position (33.3%). The mean SKILLD score was 40.0% (SD = 28.7) at baseline, increasing to 72.2% (SD = 25.4) at 12 weeks upon completion of the coaching program (t (9) = 2.956, P < 0.05). We observed a very large difference between mean baseline and exit SKILLD scores relative to the pooled standard deviation, resulting in an effect size estimate of 1.13 indicative of a large learning effect. The mean A1C levels at baseline screening was 8.3% (SD = 3.0) and 7.6% (SD = 3.0) at exit screening, representing a 0.7% decrease (p = 0.4730). No statistically significant differences were observed between depression (p = 0.786) or anxiety (p = 1.000) measures at baseline compared to exit. Training and coaching programs for hard-to-reach agricultural and meat processing workers must be culturally, linguistically, and literacy appropriate for both coaches and clients. The program must be feasible and sustainable, focus on empowering community members, capitalize on technological advances and persisting new-normals from the COVID-19 pandemic as well as dismantle common systemic barriers to health and understanding lived-experiences of agricultural working populations in rural regions.

What influences antibiotic initiation? Developing a scale to measure nursing behaviour in residential aged-care facilities.

The purpose of the current study was to develop and assess the psychometric properties of a measure that captures nursing behaviours that have the potential to influence the initiation of antibiotics in residential aged-care facilities. Cross-sectional online survey. One hundred and fifty-seven nurses completed an online survey. The survey consisted of two clinical vignettes and measures of tolerance of uncertainty and anxiety. The vignettes consisted of the most common presentations (urinary tract infections and upper respiratory tract infections) of two hypothetical residents in aged-care facilities. The vignettes provided participants with incremental information with varying levels of symptoms, input from other people and availability of test results. Both vignettes were subjected to exploratory factor analysis. The results focus on the 16 items in the second vignette which resulted in the extraction of three factors. The derived factors were labelled as follows: (i) Noting and Calling GP, (ii) Consult a Colleague and (iii) Immediate Assessment and Antibiotics. Reliability analysis revealed excellent to satisfactory reliability. All three scales were significantly correlated with measures of clinical tolerance of uncertainty, and the 'noting and calling GP' scale was also negatively correlated with measures of anxiety and general tolerance of uncertainty. The measure showed satisfactory reliability and validity for capturing nursing behaviours that have the potential to influence decisions regarding antibiotics. As such, the current study provides a first step towards addressing the lack of ecologically valid measures that capture the complex and nuanced context of nurses' behaviours in RACF that have the potential to inform future stewardship interventions.

Whistleblowing and Corrupt Tendencies among Selected Employees in Three Public Organizations

Anti-corruption efforts are often predicated on how to encourage whistleblowing and discourage corruption. To strengthen the anti-corruption drives, previous studies underscored the need for more research on psychological variables that may be connected with whistleblowing and corruption. This study, therefore, tested the extent to which employees in public sector service occupations are likely to engage in corruption and whistleblowing when they condone corruption, are less apprehensive about punishment, and can justify punishable work behaviors. This correlational study involved 331 employees (155 males; 176 females) of public sector organizations (110 health workers; 116 police personnel; 105 teachers), whose had a mean age of 43.01 years (SD = 7.86). They completed measures of corruption tolerance, punishment anxiety, workplace neutralization, whistleblowing intentions, and corrupt tendencies. Results of the 2-step hierarchical multiple regression analyses showed that whistleblowing intentions significantly reduced as employees condoned corruption, were afraid of punishment, and justified punishable work behaviors. Corrupt tendencies significantly increased as employees overlooked corruption and were able to justify punishable work behaviors, but decreased significantly as they became apprehensive of punishment. Based on these results, public sector organizations, especially the police, health, and education, should institute policies and implement psychological strategies that reduce the corruption-tolerant climate in the workplace; by increasing the fear of punishment for corruption and encouraging moral obligations to whistle-blow corruption among employees.

Early life consumption of a "processed" diet high in advanced glycation end products impairs memory function and alters the gut microbiome in rats

Recent evidence indicates that “ultra-processed” foods constitute ~65% of total energy intake among children in the U.S. The impacts of excessive processed food consumption during development are poorly understood, in part because there are neither clear definitions of, nor a robust classification system accounting for, the complexity of food processing variables and how they interrelate in final food products. Heat treatment, a common form of food processing, can induce the chemical Maillard reaction and lead to foods rich in advanced glycation end products (AGEs). The neurocognitive implications of high levels of AGE consumption, particularly during early life, are unknown. Here, we used a rat model to evaluate the effects of adolescent consumption of a heat-treated diet high in AGEs on cognition and the gut microbiome in adulthood. In a series of studies, rats received either an otherwise healthy AGE-rich diet (AGE rats; AIN-93G diet heated at 160ºC for 60min) or a non-AGE-rich diet (CTL rats; AIN-93G diet without heat treatment) during adolescence (postnatal days 26-60). Metabolic, behavioral, and gut microbiome assessments were performed in adulthood. Results revealed that AGE rats exhibited hippocampal (HPC)-dependent memory deficits relative to CTL rats in the absence of altered body weight, body composition, glucose tolerance, and behavioral measures of anxiety. Administering a drug to break down AGEs (alagebrium; 1mg/kg/day) concomitantly with the heat-treated diet prevented memory impairments, supporting a causal role of AGEs in early life diet-induced HPC dysfunction. Microbiome sequencing analyses revealed that AGE rats had substantially reduced abundance of the bacterial genus Lactococcus relative to controls, and Lactococcus abundance was strongly correlated with memory performance. Administration of Lactococcus lactis by oral gavage (109 colony forming units/day) from PN 26-40 during exposure to the heat-treated diet rescued the AGE diet-induced memory impairments. Collective findings from this work identify a connection between a specific food processing variable (i.e., increased dietary AGEs through heat treatment), the gut microbiome, and impaired neurocognition.

Swedish massage as an adjunct approach to Help suppOrt individuals Pregnant after Experiencing a prior Stillbirth (HOPES): a convergent parallel mixed-methods single-arm feasibility trial protocol

BackgroundWomen experiencing pregnancy after stillbirth experience high levels of anxiety, fear and depression. Standard antenatal care may be emotionally unsuitable for many women at this time, and there is a lack of evidence on what interventions or approaches to care might benefit these women. Therapeutic massage may assist women after stillbirth by decreasing anxiety, worry and stress.ObjectiveThis paper outlines the objectives, methodology, outcome and assessment measures for the Helping suppOrt individuals Pregnant after Experiencing a Stillbirth (HOPES) feasibility trial which evaluates massage as an adjunct approach to care for pregnant women who have experienced a prior stillbirth. It also outlines data collection timing and considerations for analysing the data.MethodsHOPES will use a convergent parallel mixed-methods, single-arm repeated measures trial design in trained massage therapists’ private clinics across Australia. HOPES aims to recruit 75 individuals pregnant after a previous stillbirth. The intervention is massage therapy treatments, and participants will receive up to five massages within a 4-month period at intervals of their choosing. Primary quantitative outcomes are the feasibility and acceptability of the massage intervention. Secondary outcomes include determining the optimal timing of massage therapy delivery and the collection of measures for anxiety, worry, stress and self-management. A thematic analysis of women’s experiences undertaking the intervention will also be conducted. A narrative and joint display approach to integrate mixed-methods data is planned.DiscussionThe HOPES study will determine the feasibility and preliminary evidence for massage therapy as an intervention to support women who are pregnant after a stillbirth.Trial registration.ClinicalTrials.gov NCT05636553.
