Restless sleep is associated with increased anxiety in physical therapy students: a cross sectional survey study

BackgroundSleep and mental health are intimately related and shown to impact graduate students enrolled in health sciences programs, including physical therapy education. Doctorate of Physical Therapy (DPT) students’ attitudes and behaviors surrounding sleep and whether these factors are associated with mental health are unknown. This study aimed to describe sleep behaviors and attitudes of entry-level DPT students and to explore the relationship between subjectively reported sleep quality and self-reported symptoms of anxiety in these students.MethodsA cross-sectional online survey consisting of the Sleep Practices and Attitudes Questionnaire (SPAQ), the Generalized Anxiety Disorder-7 (GAD-7) questionnaire, and demographic questions were used. Analyses investigated sleep behaviors and attitudes, along with the relationship (unadjusted odds ratio) between restless sleep and anxiety in DPT students in hybrid and traditional DPT programs across the United States (US).ResultsA total of 271 DPT students completed the survey. A majority of students reported feeling tired during most days (80.8%, n = 219), a quarter of participants (24.7%) reported having a history of trouble sleeping and four (1.5%) reported being diagnosed with a sleep disorder. Of those who reported their sleep duration, participants slept an average of 6.86 h. The mean GAD-7 score was 7.68 (SD = 4.90), suggestive of mild anxiety. Sixty-seven (24.7%) reported having a diagnosed anxiety disorder, with generalized anxiety being the most common diagnosis. Those who reported having restless sleep were 4.09 times more likely to have moderate to severe anxiety [unadjusted odds ratio = 4.09 (95% CI 2.27,7.35; p < 0.001)] compared to those who reported restful sleep.ConclusionsDPT students who rated sleep as restless exhibit signs of poor subjective sleep quality associated with an increased risk of experiencing moderate to severe anxiety compared to students who had restful sleep. Students reported behaviors surrounding sleep that may contribute to anxiety. These findings have implications for including sleep and mental health education and practices within DPT programs.

A Review of Survey Instruments and Pharmacy Student Outcomes for Stress, Burnout, Depression and Anxiety.

While the need to measure burnout, stress and mental health among pharmacy students has been emphasized in the literature, there is limited information on which validated scales should be used. The objective of this scoping review was to identify published studies that used validated scales for burnout, stress and mental health among pharmacy students to provide recommendations for implementation at schools/colleges of pharmacy. Thirty-two out of 153 articles published in the United States from 1 January 2000 to 30 September 2022 were included and categorized into studies measuring stress (20), burnout (4) and depression/anxiety (8). The most common validated scales used to assess stress and burnout among pharmacy students were the Perceived Stress Scale (PSS) and the Maslach Burnout Inventory and the Oldenburg Burnout Inventory, respectively. For mental health, anxiety was most commonly investigated using a variety of scales such as the Generalized Anxiety Disorder-7; the Patient Health Questionnaire, 9-item was used to measure depression in two studies. Validity, ease of use, cost and generalizability are important considerations for selecting a scale. The PSS has been studied extensively in pharmacy students and has been correlated with other well-being domains. Studies that measured burnout and mental health (specifically, depression and anxiety) have less published evidence among pharmacy students.

Addressing Mental Health in Rural Settings: A Narrative Review of Blueberry Supplementation as a Natural Intervention.

Depression and anxiety are major public health issues; however, there is an unmet need for novel, effective, and accessible treatments, particularly in rural communities. Blueberries are an unexplored nutraceutical for these conditions due to their excellent nutritional profile, with particularly high levels of polyphenols and anthocyanins and benefits on mood, cognition, and health. Here, we present a narrative review of the literature concerning the etiology and treatments of major depressive disorder (MDD) and generalized anxiety disorder (GAD). In both animal and human studies, blueberry supplementation can ameliorate behavioral symptoms of both anxiety and depression. The mechanistic underpinnings of these behavioral improvements are not fully defined, but likely involve biochemical alterations in the gut-brain axis, including to inflammatory cytokines, reactive oxygen species, and growth factors. We also review the limitations of traditional therapies in rural settings. Finally, we assess the potential benefit of nutraceutical interventions, particularly blueberries, as novel therapeutics for these distinct, yet related mental health issues.

Effectiveness of Combined Pulmonary Rehabilitation and Progressive Muscle Relaxation in Treating Long-Term COVID-19 Symptoms: A Randomized Controlled Trial

Background: The aim of this study was to investigate the effects of pulmonary rehabilitation (PR) and additional progressive muscle relaxation (PMR) techniques in patients with long-term COVID-19 symptoms. Methods: We included 61 patients with long COVID-19 symptoms and randomly assigned them to two groups: PR only (group 1 with 30 subjects) and PR with PMR (group 2 with 31 subjects). The PR program consisted of gradual aerobic conditioning, strength training, and breathing exercises. Group 2 received additional 20 min daily sessions of progressive muscle relaxation techniques. Results: Following a 21-day intervention, it was observed that both groups had noteworthy improvements in lung function, exercise capacity, and sleep quality with statistical significance (p &lt; 0.0001). Group 2 showed significant improvements in overall health (as measured by the General Health Questionnaire-12), patient health (as assessed by the Patient Health Questionnaire-9), general anxiety levels (as indicated by the Generalized Anxiety Disorders Scale-7), and sleep quality (as measured by the Pittsburgh Sleep Quality Index), with statistical significance (p &lt; 0.0001), compared to group 1. Moreover, the statistical analysis demonstrated no significant difference in exercise capacity improvement between group 1 and group 2, as indicated by a p-value of 0.1711. Conclusions: The addition of progressive muscle relaxation to pulmonary rehabilitation significantly enhances mental health outcomes, particularly in reducing anxiety and improving sleep quality, for patients with long-term COVID-19 symptoms. These findings suggest that incorporating PMR into PR programs offers a valuable non-pharmacological approach to improving overall patient well-being during long-term COVID-19 recovery.

Insomnia as a predictor of treatment outcomes in adolescents receiving concentrated exposure treatment for OCD

BackgroundResearch suggests that individuals with obsessive-compulsive disorder (OCD) frequently experience insomnia. Some previous studies have suggested that insomnia may predict treatment outcomes, but the evidence is limited, especially for adolescents. This study examined the prevalence of insomnia in an adolescent OCD patient sample, explored the correlation between OCD and insomnia, and tested whether levels of insomnia at baseline predict outcomes for adolescent patients receiving the Bergen 4-Day Treatment (B4DT) for OCD.MethodsForty-three adolescent OCD patients who received B4DT were selected for this study. Treatment outcome was quantified as change in Children Yale-Brown Obsessive Compulsive Scale (CY-BOCS) scores across time from pre- to posttreatment and 3-month follow-up. Insomnia symptoms were measured by the Bergen Insomnia Scale (BIS). Linear mixed models were used to examine the relationship between the BIS and changes in CY-BOCS scores. We controlled for symptoms of general anxiety disorder measured by the GAD-7 and depression symptoms measured by the PHQ-9.ResultsIn this sample, 68.4% of the patients scored above the cutoff for insomnia on the BIS. There was a moderate correlation between baseline CY-BOCS and BIS that did not reach statistical significance (r = .32, p = .051). High BIS scores before treatment were significantly associated with poorer treatment outcomes, as measured by changes in CY-BOCS over time (p = .002). The association between baseline insomnia and change in OCD symptoms remained significant (p = .033) while controlling for GAD-7 and PHQ-9.ConclusionInsomnia is common among adolescents with OCD, and these data suggest that these patients may be at increased risk for poor treatment outcomes. Future research to explore mechanisms and adjunctive treatments is warranted.Trial registrationThe study was approved by the Regional Committee for Medical and Health Research Ethics of Northern Norway (REK Nord: 2023/606482).

Clinical Effects of Asynchronous Provider-Guided Practice Sessions During Blended Care Therapy for Anxiety and Depression: Pragmatic Retrospective Cohort Study.

Blended care therapy models are intended to increase the efficiency and effectiveness of evidence-based psychotherapy by combining synchronous and asynchronous components of care. This retrospective cohort study evaluated the clinical effects of synchronous video therapy sessions and asynchronous guided practice session elements on anxiety and depression in a blended care therapy program, with a novel focus on asynchronous provider feedback messages. Participants were adults (N=33,492) with clinical symptoms of anxiety (Generalized Anxiety Disorder 7-item scale [GAD-7] score of ≥8) and depression (Patient Health Questionnaire 9-item scale [PHQ-9] score of ≥10) at intake. Symptom trajectories were evaluated via individual growth curve models. Time-varying covariates evaluated effects of synchronous video session attendance and the presence or absence of each asynchronous guided practice session element occurring within 7 days and 8-14 days prior to each clinical outcome assessment. Guided practice session elements included client digital lesson completion, client digital exercise completion, and feedback messages sent by providers. Approximately 86.6% (29,012/33,492) of clients met criteria for clinical improvement by end of care (median 6, IQR 4-8 synchronous sessions). Synchronous video session attendance and client digital lesson completion in the past 7 days and in the past 8-14 days were each uniquely and significantly associated with lower GAD-7 scores (video session effects: bsession7=-0.82, bsession8-14=-0.58, P values<.001; digital lesson effects: blesson7=-0.18, blesson8-14=-0.26, P values <.001) and PHQ-9 scores (video session effects: bsession7=-0.89, bsession8-14=-0.67, P values <.001; digital lesson effects: blesson7=-0.12, blesson8-14=-0.30, P values <.001). Client digital exercise completion in the past 8-14 days was significantly associated with lower GAD-7 scores (bexercise8-14=-0.10; P<.001) but exercise completion in the 7 days prior to clinical outcome assessment was not (bexercise7=0.00; P=.89). Exercise completion in the past 7 days was significantly associated with lower PHQ-9 scores (bexercise7=-0.16; P<.001) but exercise completion in the past 8-14 days was not (bexercise8-14=-0.05; P=.09). Provider feedback messaging in the past 7 days and in the past 8-14 days was significantly associated with lower GAD-7 and PHQ-9 scores, respectively (GAD-7: bfeedback7=-0.12, P<.001; bfeedback8-14=-0.07, P=.004; PHQ-9: bfeedback7=-0.15, P<.001; bfeedback8-14=-0.08, P=.01). Provider feedback between synchronous therapy sessions provided significant benefit for symptom reduction, beyond the effects of client digital engagement and synchronous video sessions. When guided practice sessions are well integrated into care, blended care therapy provides meaningful improvements upon the traditional, synchronous session-only therapy model. Provider guidance and feedback for clients between synchronous sessions support more efficient and effective mental health care overall.

Dopaminergic- and Serotonergic-Dependent Behaviors Are Altered by Lanthanide Series Metals in Caenorhabditis elegans.

The lanthanide series elements are transition metals used as critical components of electronics, as well as rechargeable batteries, fertilizers, antimicrobials, contrast agents for medical imaging, and diesel fuel additives. With the surge in their utilization, lanthanide metals are being found more in our environment. However, little is known about the health effects associated with lanthanide exposure. Epidemiological studies as well as studies performed in rodents exposed to lanthanum (La) suggest neurological damage, learning and memory impairment, and disruption of neurotransmitter signaling, particularly in serotonin and dopamine pathways. Unfortunately, little is known about the neurological effects of heavier lanthanides. As dysfunctions of serotonergic and dopaminergic signaling are implicated in multiple neurological conditions, including Parkinson's disease, depression, generalized anxiety disorder, and post-traumatic stress disorder, it is of utmost importance to determine the effects of La and other lanthanides on these neurotransmitter systems. We therefore hypothesized that early-life exposure of light [La (III) or cerium (Ce (III))] or heavy [erbium (Er (III)) or ytterbium (Yb (III))] lanthanides in Caenorhabditis elegans could cause dysregulation of serotonergic and dopaminergic signaling upon adulthood. Serotonergic signaling was assessed by measuring pharyngeal pump rate, crawl-to-swim transition, as well as egg-laying behaviors. Dopaminergic signaling was assessed by measuring locomotor rate and egg-laying and swim-to-crawl transition behaviors. Treatment with La (III), Ce (III), Er (III), or Yb (III) caused deficits in serotonergic or dopaminergic signaling in all assays, suggesting both the heavy and light lanthanides disrupt these neurotransmitter systems. Concomitant with dysregulation of neurotransmission, all four lanthanides increased reactive oxygen species (ROS) generation and decreased glutathione and ATP levels. This suggests increased oxidative stress, which is a known modifier of neurotransmission. Altogether, our data suggest that both heavy and light lanthanide series elements disrupt serotonergic and dopaminergic signaling and may affect the development or pharmacological management of related neurological conditions.

Correlation Between Anxiety, Depression and Hemodynamic Changes in Office-Based Laryngeal Surgery.

To investigate the correlation between anxiety, depression, and hemodynamic changes during office-based laryngeal surgery (OBLS). All patients undergoing OBLS between February 2024 until July 2024 were invited to participate in the study. Participants had their vital signs recorded throughout the procedure at a 5-min interval. They also had to fill the Generalized Anxiety Disorder scale-7 (GAD-7) to assess anxiety severity and the Patient Health Questionnaire-9 (PHQ-9) to assess depression severity. Demographic data included age, gender, history of smoking, history of reflux disease, history of cardiovascular diseases, type and duration of procedure. A total of 45 patients were recruited in the study. During OBLS, 35.5% of patients developed hypertension and 28.9% developed tachycardia. There was a significant increase in mean systolic blood pressure (SBP) by 30.16 mmHg (p < 0.001), in mean diastolic blood pressure (DBP) by 31.44 mmHg (p < 0.001), and in mean heart rate (HR) by 14.2 beats per minute (p < 0.001). There was also a significant decrease in the mean O2 saturation by 0.4% (p = 0.001). There was no correlation between anxiety and SBP, DBP, HR, and O2 (r < 0.1). There was also no correlation between depression levels and SBP, DBP, HR, O2 (r < 0.1). There was a significant increase in the mean SBP, DP, and HR and a significant decrease in the O2 saturation in patients undergoing OBLS. However, there was no correlation between anxiety, depression and the changes in these vital signs. Future investigations are needed to understand the causes of hemodynamic instability in OBLS. 2 Laryngoscope, 2024.

Study of Rates and Factors Associated to Psychosomatic Syndromes Assessed Using the Diagnostic Criteria for Psychosomatic Research across Different Clinical Settings

Introduction: Diagnostic Criteria for Psychosomatic Research (DCPR) serve as an instrument for identifying and classifying specific psychosomatic syndromes that are not adequately encompassed in standard nosography. The present study aimed at measuring the prevalence of DCPR syndromes in different clinical settings and exploring factors associated to such diagnoses. Methods: A cross-sectional and nationwide study recruited 6,647 patients in different clinical settings: 306 were diagnosed with fibromyalgia (FM), 333 with irritable bowel syndrome, 1,109 with migraine, 2,550 with coronary heart disease (CHD), and 2,349 with type 2 diabetes (T2D). Participants underwent DCPR diagnostic interview and were assessed for depression (Patient Health Questionnaire-9), anxiety (Generalized Anxiety Disorder 7-Item Scale), and subjective well-being (World Health Organization-5 Well-Being Index). The PsychoSocial Index was used to evaluate global well-being, stress, and abnormal illness behavior. The prevalence of DCPR diagnoses was calculated, and factors associated to such diagnoses were analyzed by logistic regression. Results: Alexithymia (64.47%), irritable mood (20.55%), and demoralization (15.60%) were the most prevalent psychosomatic syndromes, with demoralization being most common in FM (49.02%). The factors associated to DCPR diagnoses encompassed high anxiety or abnormal illness behavior, and poor well-being. Notably, stress was found to be associated specifically to FM and T2D, with OR of 1.24 (95% CI: 1.06–1.46) and 1.26 (95% CI: 1.18–1.36), respectively. Conclusion: DCPR is a clinically helpful complementary assessment tool in need of being widely implemented in clinical settings in order to have a comprehensive picture of the patients.

Executive functions in older adults with generalised anxiety disorder and healthy controls: Associations with heart rate variability, brain-derived neurotrophic factor, and physical fitness

Executive functions (EF) decline with age and this decline in older adults with generalised anxiety disorder (GAD) may be influenced by heart rate variability (HRV), brain-derived neurotrophic factor (BDNF), and physical fitness. Understanding these relationships is important for tailored treatments in this population. In this study, 51 adults with GAD (M age = 66.46, SD = 4.08) and 51 healthy controls (M age = 67.67, SD = 4.04) were assessed on cognitive inhibition (Stroop task), shifting (Trails part 4), flexibility (Wisconsin Card Sorting Test – Perseverative errors), working memory (Digit Span Backwards), IQ (Wechsler Abbreviated Scale of Intelligence), high frequency HRV, serum mature BDNF levels, and VO2 max. Results indicated that participants with GAD exhibited better cognitive inhibition compared to controls, with no general reduction in EF. Cognitive inhibition was predicted by gender, HRV, and BDNF levels, while cognitive shifting was predicted by gender and IQ, and cognitive flexibility and working memory by IQ. The enhanced cognitive inhibition in GAD participants might stem from maladaptive use of this function, characteristic of GAD, or protection from EF decline due to normal HRV. Increased BDNF levels, possibly due to good fitness, or compensatory mechanisms related to the disorder, might also play a role. These findings highlight the complexity of EF and related mechanisms in GAD, highlighting the need for interventions that consider both cognitive and physiological factors for optimal outcomes.

Efficacy of manual lymphatic drainage combined with repetitive transcranial magnetic stimulation in post-stroke complex regional pain syndrome: a pilot study

Purpose The aim of this study was to investigate the efficacy of manual lymphatic drainage (MLD) combined with repetitive transcranial magnetic stimulation (rTMS) on the recovery of upper limb in patients with post-stroke complex regional pain syndrome (CRPS). Methods This pilot study was conducted with 54 patients with post-stroke CRPS. Patients were randomized into three groups: the MLD combined with rTMS group (MLD + rTMS group), the rTMS group and the sham-rTMS group. The results of numeric rating scale (NRS), volumetric measurement, Fugl-Meyer assessment of upper extremity (FMA-UE), CRPS severity score (CSS), generalized anxiety disorder-7 (GAD-7) and patient health questionnaire-9 (PHQ-9) before and after the intervention were analyzed. Results Fifty-four participants (37 males, 17 females; mean age 66.11 ± 8.43 years; range, 18 to 85) were included in the study. Among groups, improvements were statistically significant with superiority of rTMS + MLD group after treatment (p < 0.05). NRS, GAD-7, and PHQ-9 in the rTMS + MLD group improved more significantly than those in the rTMS group (p < 0.05). Conclusion MLD combined with rTMS has an add-on efficacy on the basis of rTMS therapy in post-stroke patients, especially in pain. MLD could also have an effect on anxiety and depression.

Glycemic indicators and mental health symptoms: results from the greater Beirut area cardiovascular cohort.

Depression and anxiety present high and complex comorbidity with diabetes. One proposed explanation is that glycemic dysregulations and diabetes-related processes can influence mental health risk. We examined the associations of concurrent and prior glycemic indicators (Hemoglobin A1c (HbA1c) and fasting blood glucose (FBG) levels) with depression and anxiety symptoms in a community-based sample of middle-aged Lebanese adults. Data come from the Greater Beirut Area Cardiovascular Cohort (GBACC), with baseline and 5-year assessments of sociodemographic, lifestyle, and biological factors (n=198). Depression (Patient Health Questionnaire-9) and anxiety (General Anxiety Disorder-7) symptoms were assessed at follow-up. We investigated associations between glycemic indicators and continuous mental health scores using first linear and then piecewise regression models. Adjusted piecewise regression models showed different associations with mental outcomes across glycemic indicators in the diabetic/clinical compared to the non-diabetic range: Among participants with <126 mg/dl baseline FBG, higher FBG levels in this range were significantly associated with lower depressive (beta=-0.12, 95%CI= [-0.207, -0.032]) and anxiety symptoms (beta=-0.099, 95%CI= [-0.186, -0.012]). In contrast, among participants with baseline FBG levels ≥126 mg/dl, higher FBG levels were significantly associated with higher anxiety symptoms (beta=0.055; 95%CI= 0.008, 0.102). Higher baseline FBG levels in the ≥126 mg/dl range showed a not statistically significant trend for higher depressive symptoms. Although not significant, baseline HbA1c levels showed similar patterns with negative associations with mental health symptoms in the <6.5% range. Results show that FBG levels were associated with poorer mental health symptoms only in the clinical/diabetic range, and not in the normal range. Associations were observed with baseline glycemic indicators, highlighting potentially early and prolonged associations with mental health. Findings highlight the importance of clinical changes in glycemic indicators for mental health and motivate further research into the transition toward adverse associations between diabetes and mental health.

Psychological Impact of Covid-19 Pandemic on Health Care Workers of a Field Hospital in UN Peacekeeping Mission

Background: The Covid-19 pandemic has significantly affected the healthcare system worldwide as well as the psychological state of all. The objective of the current study was to assess the psychological conditions of the healthcare workers in Enhanced Level 1+ Hospital, Bouar, Central African Republic (CAR). This assessment can help in the guideline development and implication psychological interventions which in turn can improve the quality of life, working environment and decision-making capabilities of health care workers during widespread pandemic. Methods: This descriptive cross-sectional study was conducted on 40 medical personnel working in Enhanced Level 1+ Hospital, Bouar, Central African Republic. The study was performed from June 2022 to August 2022. Assessment of psychological status of military healthcare providers was done by analyzing the results derived from the Mental health survey, Perceived Stress Scale (PSS-10), Generalized Anxiety Disorder scale (GAD-7) and Patient Health Questionnaire (PHQ-9). Hospital records were analyzed to assess the changes in workload. Results: The working hour increased significantly from Pre Covid to Post Covid period (1920±34.1 hours/week to 2120±67.3 hours/week) although the number of weekly patients in OPD and Emergency decreased slightly from 51.9 to 40.6. Elevated mental stress was observed during outbreak (average PSS-10 score in June 22 was 20.4 which reduced to 9.7 in August). The same pattern was observed in case of GAD-7 score (15.6 to 10.8) and PHQ-9 score (12.4 to 6.1). The percentage of concerns regarding Covid19 was high during the outbreak, 37/40 (92.5%), which decreased after wards to 18/40 (45%). Conclusion: The UN field hospitals are inadequate to support mass outbreak like COVID 19 in the context of both staff and medical supplies. During Covid 19 outbreak, sharp rise of workload and difficulties in restocking of essential medical items played a vital role in the mental state of the medical professionals. The field hospitals in UN peacekeeping missions require intensive effort especially on disaster and epidemic management during pre-deployment training. Moreover, reconsidering distribution of human resources in field hospitals is also required. Bangladesh Armed Forces Med J Vol 57 No (1) June 2024, pp 35-42

The translation and validation of the surgical anxiety questionnaire into the modern standard Arabic language: results from classical test theory and item response theory analyses

BackgroundPreoperative anxiety is commonly found in patients who are waiting for surgery and can lead to negative surgical outcomes. Understanding the sources of surgical anxiety allows healthcare providers to identify at-risk patients and implement psychosocial interventions such as counseling, relaxation techniques, and cognitive‒behavioral therapy to minimize anxiety. Few comprehensive psychiatric measures are available to assess preoperative anxiety in Arabic.ObjectiveOur study aimed to translate, adapt, and validate the Surgical Anxiety Questionnaire (SAQ) into the modern standard Arabic language, also known as Fusha al-Asr Arabic.MethodsTo translate the questionnaire, the research team used the gold standard process of forward translation by two independent translators along with back translation evaluation by four trained medical doctors. A cross-sectional study was conducted using an online survey completed by 208 Arabic speakers (mean age 38 years, 44% women) from four countries. Psychometric analyses, which included internal consistency, test-retest reliability, convergent validity, confirmatory factor analysis, and item response analysis, were performed. Convergent validity tests were performed against the Generalized Anxiety Disorder 2-item Scale (GAD-2), Patient Health Questionnaire-4 (PHQ-2), Perceived Stress Scale 4 (PSS-4), and Arabic version of the Visual Analog Scale for anxiety (VAS-A).ResultsThe mean SAQ of our sample was 19.38 ± 12.63 (possible range 0–68). The Arabic SAQ translation demonstrated excellent internal consistency, with McDonald’s omega and a Cronbach’s alpha of approximately 0.90. The test-retest reliability was also high, with an intraclass coefficient of 0.94. The SAQ showed strong convergent validity against the GAD-2 (r = 0.94, p < 0.01). The SAQ also showed weak-moderate correlations with the PHQ-2 (r = 0.26, p < 0.01), PSS-4 (r = 43, p < 0.01), and VAS-A (r = 0.36, p < 0.01) scores. The original three-factor structure was supported by confirmatory factor analysis, confirming the original structure reported in the original English language version. The results for fitness indices showed acceptable preliminary results (CFI/TLI approximately 0.90), and deleting some items improved the model fit (CFI/TLI > 0.90, RMSEA < 0.08). We suggest retaining the original factorial solution until further validation studies can be conducted. The item response theory (IRT) results identified no items that were excessively difficult or subject to guessing. The multidimensional IRT provided evidence that the SAQ items form a multidimensional scale assessing surgical anxiety that fits the classical model reasonably well.ConclusionThe SAQ has demonstrated acceptable reliability and validity; thus, it is a trustworthy and valid tool for evaluating preoperative anxiety in Arabic speakers. Future research could benefit from using the SAQ in both surgical and psychiatric research.

Were there any missing mediators between visual impairment and anxiety symptoms? Results from Chinese Longitudinal Healthy Longevity Survey.

Visual impairment, encompassing low visual acuity and visual field loss, significantly impacts the older adult population worldwide, leading to increased disability and mortality risks. Recent studies suggest a strong association between visual impairment and anxiety, particularly among older adults. This study aims to explore the relationship between visual impairment and anxiety symptoms in older adult individuals in China, and to investigate potential mediating factors. Data for this study were derived from the 2018 Chinese Longitudinal Healthy Longevity Survey (CLHLS), including 11,702 participants aged 65 and older. Visual impairment was assessed through self-reported visual function, while anxiety symptoms were measured using the 7-item Generalized Anxiety Disorder scale (GAD-7). Additional assessments included sleep quality and duration, exercise status, and dietary diversity. Logistic regression models and mediation analysis were employed to explore associations and mediating effects. The findings indicate that visual impairment is significantly associated with increased anxiety symptoms among the older adult (OR = 1.51, 95% CI: 1.32-1.72, p < 0.001). Mediation analysis revealed that sleep quality, dietary diversity score (DDS), and plant-based DDS significantly mediated the relationship between visual impairment and anxiety. In contrast, sleep duration, exercise, and animal-based DDS did not show significant mediating effects. Visual impairment is a crucial predictor of anxiety symptoms in the older adult. Improving sleep quality and promoting a diverse plant-based diet may mitigate anxiety symptoms in this population. Interventions targeting these areas could enhance the mental health and quality of life of older adult individuals with visual impairment.

How accurately can supervised machine learning model predict a targeted psychiatric disorder?

BackgroundHoarding disorder (HD) is characterized by a compulsion to collect belongings, and to experience significant distress when parting from them. HD is often misdiagnosed for several reasons. These include patient and family lack of recognition that it is a psychiatric disorder and professionals’ lack of relevant expertise with it. This study evaluates the ability of a supervised machine learning (ML) model to match the diagnostic skills of psychiatrists when presented with equivalent information pertinent to symptoms of HD.MethodsFive hundred online participants were randomly recruited and completed the Hoarding Rating Scale-Self Report (HRS-SR) and the Generalized Anxiety Disorder 7-item (GAD-7) scale. Responses to the questionnaires were read by an ML model. Responses to the HRS-SR were then converted into anonymized, random-equivalent texts. Each of these individual texts was presented in random order to two experienced psychiatrists who were independently asked for a provisional diagnosis - e.g.; the presence or absence of HD. In case of disagreement between the two assessors, a third psychiatrist broke the tie. A decision tree classification model was employed to predict clinical HD using self-report data from two psychological tests, the HRS-SR and GAD-7. The target variable was whether a participant had clinical HD, while the predictive variables were the continuous scores from the HRS-SR and GAD-7 tests. The model’s performance was evaluated using a confusion matrix, which compared the observed diagnoses with the predicted diagnoses to assess accuracy.ResultsAccording to the psychiatrists, approximately 10% of the participants fulfilled DSM-5 diagnostic criteria for HD. 93% of the clinician-identified cases were identified by the ML model based on HRS-SR and GAD-7 scores. A decision tree plot model demonstrated that about 60% of the cases could be detected by the HRS-SR alone while the rest required a combination of HRS-SR and GAD-7 scores. ML evaluation metrics showed satisfactory performance, with a Matthews Correlation Coefficient of 55%; Area Under Curve (AUC), 79%; a Negative Predictive Value of 76%; and a False Negative Rate of 24%.ConclusionsStudy findings strongly suggest that ML can, in the future, play a significant role in the risk assessment of psychiatric disorders prior to face-to-face consultation. By using AI to scan big data questionnaire responses, wait time for seriously ill patients can be substantially cut, and prognoses substantially improved.

Patient and family aftercare enhance interactions between Helicopter Emergency Medicine Services and former patients and families

BackgroundHelicopter Emergency Medical Services (HEMS) in the United Kingdom (UK) deliver enhanced care to high-acuity, critically ill and injured patients. To enable patients to meet the HEMS team who treated them, many services within the UK have developed or are in the process of developing a Patient and Family Aftercare Service (PFAS). This study aims to evaluate whether the introduction of PFAS mitigates anxiety associated with patient aftercare visits.MethodsA service evaluation of anxiety in HEMS team members before and after patient aftercare visits were conducted. The study was carried out between 1 September 2023, and 31 October 2023, and patient visits were undertaken between March 2022 and July 2023. An electronic survey was distributed to the respondents who provided informed consent for participation. The survey comprised the validated generalised anxiety disorder anxiety scale (GAD-7) and five additional contextualised statements developed through the wider PFAS. Anonymised data were collected using REDCap, a secure electronic database and was analysed in R programming. Free-text comments were reported by content analysis, placed into themes, and discussed with a narrative to complement the quantitative analysis.ResultsOf the 33 recipients, 25 completed the questionnaire. Between the pre- and post-aftercare visits, a statistically significant difference was found between scores for GAD-7 (0.004, p < 0.05) and contextualised statements (0.001, p < 0.05). In addition, six broad themes were identified through content analysis. These include the emotional impact of patient interaction, coping strategies and structural changes in the aftercare system, challenges in patient and family expectations, anxieties relating to operational commitments, memory and recall of the incident, and a positive impact on personal growth.ConclusionAnxiety related to patient aftercare visits was reduced when measured before and after the patient visits. Following this service evaluation, we can hypothesise that within pre-hospital care, PFAS plays an important structural role. Future research should focus on affirming the correct tool to measure anxiety in multi-disciplinary teams and prospectively evaluating these methods collaboratively across multiple pre-hospital services.

Treatment as a moderator and executive function as a mediator of the effect of a mindfulness ecological momentary intervention for generalized anxiety disorder.

Theory and research indicated that executive functioning (EF) correlated with, preceded, and stemmed from worry in generalized anxiety disorder (GAD). The present secondary analysis (Zainal & Newman, 2023b) thus determined whether EF domains mediated the effect of a 14-day (5 prompts/day) mindfulness ecological momentary intervention (MEMI) against a self-monitoring control (SM) for GAD. Participants (N = 110) diagnosed with GAD completed self-reported (Attentional Control Scale, GAD Questionnaire, Perseverative Cognitions Questionnaire) and performance-based tests (Letter-Number Sequencing, Stroop, Trail Making Test-B, Verbal Fluency) at baseline, post-treatment, and one-month follow-up (1MFU). Causal mediation analyses determined if pre-post changes in EF domains preceded and mediated the effect of MEMI against SM on pre-1MFU changes in GAD severity and trait repetitive negative thinking (RNT). MEMI was more efficacious than SM in improving pre-post inhibition (β = -2.075, 95% [-3.388, -0.762], p = .002), working memory (β = 0.512, 95% [0.012, 1.011], p = .045), and set-shifting (β = -2.916, 95% [-5.142, -0.691], p = .010) but not verbal fluency and attentional control. Within groups, MEMI but not SM produced improvements in all examined pre-post EF outcomes except attentional control. Only pre-post improvements in inhibition mediated the effect of MEMI against SM on pre-1MFU reductions in GAD severity (β = -0.605, 95% [-1.357, -0.044], p = .030; proportion mediated = 7.1%) and trait RNT (β = -0.024, 95% [-0.054, -0.001], p = .040; proportion mediated = 7.4%). These patterns remained after conducting sensitivity analyses with non-linear mediator-outcome relations. Optimizing MEMI for GAD might entail specifically boosting inhibition plausibly by augmenting it with dialectical behavioral therapy, encouraging high-intensity physical exercises, and targeting negative emotional contrast avoidance.

Clinical characteristics of 2378 patients presenting with headache disorders to headache clinics in Japan: A clinic-based multicenter study

BackgroundThere are reports from single-center studies on patients visiting headache clinics; however, few multicenter studies have been conducted in Japan. This study aims to address this gap by conducting a multicenter analysis of the clinical characteristics, headache types, severity, and psychiatric comorbidities of patients attending headache clinics. MethodsWe prospectively evaluated the clinical characteristics of 2378 patients with headache disorders visiting three headache clinics. Baseline demographics, such as the visual analog scale (VAS), and psychiatric assessments, such as the Generalized Anxiety Disorder-7 (GAD-7) and the Patient Health Questionnaire-9 (PHQ-9), were evaluated. Headache types were classified as migraine, tension-type headache (TTH), trigeminal autonomic cephalalgias (TACs), other primary headache disorders (OPHDs), and secondary headache. Parameters were compared between headache types using the Kruskal–Wallis test or analysis of covariance, as appropriate. ResultsThe most common headache type was migraine (78.8 %), followed by TTH (12.2 %), secondary headache (5.5 %), OPHDs (2.1 %), and TACs (1.6 %). Patients with migraine were significantly younger at first consultation (median age 32.0) than those with other headache types (TTH; 47.0, TACs; 39.0, OPHDs; 49.5, and secondary headache; 47.0). Patients with TACs exhibited the highest severity and psychiatric symptoms, with VAS (median 90.0), GAD-7 (7.0), and PHQ-9 (7.5) scores significantly higher than those of other headache type (migraine; 70.0, 5.0, 5.0, TTH; 50.0, 4.0, 4.0, OPHDs; 65.0, 4.0, 3.5, and secondary headache; 60.0, 3.0, 3.5: p<0.001, p=0.019, p<0.001). ConclusionMost patients visiting headache clinics had migraine; patients with TACs showed significantly higher headache severity and psychiatric symptoms than those with other headache types.

Effect of Age at Liver Transplant on Anxiety, Depression, and Quality of Life Among Adolescents.

Introduction: Life expectancy for pediatric liver transplant patients has increased over the past decade. Different stages of the transplant process can impact patients' quality of life (QOL) and create psychological and physical stressors. This study explored whether age at transplant affected adolescents' feelings of anxiety, depression, and QOL. Design: In this cross-sectional quantitative study, data were collected on 22 adolescent patients aged 13-18 who received a transplant at least 12 months before enrollment. This cohort was divided into 2 groups based on their age at transplant: Group 1 (0-5 years) and Group 2 (6-18 years). To assess transplant-related anxiety, depression, and QOL, participants completed 3 surveys: the Generalized Anxiety Disorder-7 (GAD-7), the Patient Health Questionnaire-9 (PHQ-9), and the Pediatric Quality of Life Inventory™ Transplant Module (PedsQL TM). Results: Group 1 experienced less anxiety and fewer problems based on GAD-7 scores but reported stronger feelings of depression based on PHQ-9 scores. Based on the PedsQL TM scale, Group 1 had higher mean scores compared to Group 2 across all components (mean difference range: 7.2- 27.3; Cohen's d range: 0.27 - 1.13). The largest difference between the 2 groups was observed on the PedsQL TM scale's How I Look (Group 1 mean 81.1 vs. Group 2 mean 53.8; Cohen's d: 1.13; P = 0.015), Conclusion: In this cohort, age at transplant affected adolescents' feelings of anxiety, depression, and QOL. Awareness of these findings can help clinicians screen for and address mental health issues.
