Abstract:

Early life stress has been shown to exert profound short- and long-term effects on human physiology both in the central nervous system and peripherally. Early life stress has demonstrated clear association with many psychiatric disorders including major depression, posttraumatic stress disorder, and bipolar disorder. The Diagnostic and Statistics Manuel of Mental Disorders (DSM) diagnostic categorical system has served as a necessary framework for clinical service, delivery, and research, however has not been completely matching the neurobiological research perspective. Early life stress presents a complex dynamic featuring a wide spectrum of physiologic alterations: from epigenetic alterations, inflammatory changes, to dysregulation of the hypothalamic pituitary axis and has further added to the challenge of identifying biomarkers associated with psychiatric disorders. The National Institute of Mental Health’s proposed Research Domain Criteria initiative incorporates a dimensional approach to assess discrete domains and constructs of behavioral function that are subserved by identifiable neural circuits. The current neurobiology of early life stress is reviewed in accordance with dimensional organization of Research Domain Criteria matrix and how the findings as a whole fit within the Research Domain Criteria frameworks.

Abstract:

Although the literature reports a higher incidence of anxiety disorders in women, the majority of basic research has focused on male rodents, thus resulting in a lack of knowledge on the neurobiology of anxiety in females. Bridging this gap is crucial for the design of effective translational interventions in women. One of the key brain mechanisms likely to regulate anxious behavior is adult hippocampal neurogenesis (AHN). This review paper aims to discuss the evidence on the differences between male and female rodents with regard to anxiety-related behavior and physiology, with a special focus on AHN. The differences between male and female physiologies are greatly influenced by hormonal differences. Gonadal hormones and their fluctuations during the estrous cycle have often been identified as agents responsible for sexual dimorphism in behavior and AHN. During sexual maturity, hormone levels fluctuate cyclically in females more than in males, increasing the stress response and the susceptibility to anxiety. It is therefore of great importance that future research investigates anxiety and other neurophysiological aspects in the female model, so that results can be more accurately applicable to the female population.

Abstract:

RésuméUn des aspects essentiels de la cognition chez l’homme est lié à la qualité de son sommeil qui semble conditionner la fonction de mémorisation aussi bien que d’attention. Il est d’ailleurs remarquable de constater que les molécules hypnotiques peuvent avoir des effets différents sur la cognition, de façon peut-être corrélée à leur action sur les differents stades de sommeil et sûrement liée à la persistance de leurs effets sur la vigilance pendant la journée.Il est désormais classique de différencier l’anxiété généralisée (AG) de la dépression majeure (DM) par la mise en évidence des variations circadiennes marquées sur les plans clinique, polygraphique, hormonal et physiologique dans la dépression alors qu’une non-rythmicité de l’anxiété généralisée est habituellement revendiquée. Certains rythmes peuvent néanmoins être mis en évidence, bien que de façon moins marquée dans cette pathologie. Ainsi, des variations circadiennes sont souvent notées sur le plan clinique, un maximum d’anxiété et d’attaques de panique se produisant l’après-midi et en début de soirée au moment de l’acmé de la courbe de température centrale. De même, certaines particularités sont notables au niveau de l’analyse des enregistrements polygraphiques de sommeil et des niveaux plasmatiques hormonaux.Un des faits les plus troublants est de constater une certaine symetrie dans l’expression clinique et polygraphique des troubles dans la dépression majeure et l’anxiété généralisee: la DM est classiquement associée à un réveil très douloureux en milieu de nuit et à une désorganisation de la structure polygraphique du sommeil dans la deuxième partie de la nuit, moments où la température centrale après avoir atteint son niveau minimal amorce une remontée. A l’inverse, l’AG est à son maximum en fin d’après-midi et comporte une insomnie de la première partie de la nuit objectivée par un aspect haché du sommeil observable entre le moment du coucher et le milieu de la nuit, période où la temperature centrale est dans une phase descendante.Certaines anomalies peuvent être également retrouvées aux niveaux physiologique et biologique. Ces ditférentes observations devraient sans doute, dans l’avenir, susciter des recherches chronobiologiques plus nombreuses et influencer les habitudes de prescription.

Abstract:

ABSTRACT:Objective: To assess effect of perioperative music intervention on maternal anxiety levels, physiologic metrics, and medication use for anxiety, nausea and pain during and after scheduled cesarean section. Methods: Women assigned to music intervention group were compared against controls. Physiologic metrics, medication requirements, and STAI scores were assessed for all participants. Results: 50 women were enrolled, assigned to either music intervention (n=25) or control (n=25) and analyzed. Physiologic metrics were similar between groups. Antiemetic, anxiolytic, and analgesic medication use intraoperatively and postoperatively were not significantly different. State and Trait scores by the STAI did not vary significantly by intervention (p=0.09). STAI scores before and after procedure demonstrated the least change for the intervention group (r=0.6) when compared to controls (r=0.2; p<0.05).Conclusion: Contrary to studies with formal music therapy, our data do not support use of patient-selected music as an intervention to reduce maternal anxiety or need for analgesics, anxiolytics, or antiemetics with scheduled cesarean section.

Abstract:

I qualified in Belfast (Queen's University) in 1942. I did not have any interest in psychiatry, having the ambition to become a clinical physiologist. I had worked with Henry Barcroft, who was professor of physiology. I joined the Army and later the Airborne Forces. Fortunately, the casualties expected amongst the medical personnel of the 6th Airborne Division during the Normandy incursion did not occur, leaving myself and other medical colleagues, who had just completed our parachute training, redundant. I was posted to France and in the late summer of 1944 found myself regimental medical officer to the 1st Battalion The Herefordshire Regiment. I must confess that it never occurred to me during the winter and spring of 1944–1945 that the emotional reactions and the physical expressions of anxiety encountered, particularly amongst the young conscripts, had anything to do with the subject of psychiatry.

Abstract:

Purpose The purpose of this exploratory pilot study was to examine the associations of state and trait anxiety with glycemic control, self-management, and diabetes-specific quality of life (QOL) in youth 10 to 16 years of age with type 1 diabetes (T1D). Methods Bivariate Pearson correlations and multiple linear regression modeling were conducted to examine the relationship among anxiety symptoms, hemoglobin A1C (A1C), self-management, QOL, and covariates. Results A sample of 67 adolescents was 50.7% female, and 87.1% were non-Hispanic white, with a mean ± SD age of 13.4 ± 1.85 years and an A1C of 8.3% ± 1.2% (67 mmol/mol). Higher state anxiety was correlated with older age. Better self-management was correlated with lower trait anxiety and lower state anxiety. Higher state and trait anxiety were associated with poorer self-management. Higher state anxiety was associated with higher A1C. Higher trait anxiety was associated with poorer diabetes-specific QOL. Conclusions State and trait anxiety may differentially affect diabetes outcomes. State anxiety may be a modifiable target for physiologic (A1C) and psychosocial (QOL) outcomes in youth with T1D, while trait anxiety may be a modifiable target for psychosocial outcomes (QOL). Anxiety symptoms should be assessed at regular clinic visits. Interventions to improve anxiety symptoms may in turn improve physiologic and psychosocial outcomes.

Abstract:

Background: Invasive diagnostic tests such as angiography cause stress and anxiety in patient and most of them experience relatively high levels of anxiety. Objectives: The aim of this study was to evaluate the effect of aromatherapy on anxety and physiologic parameters of patients undergoing angiography. Materials and Methods: This clinical trial was performed in the angiography department of Heshmat hospital in north of Iran. Eighty patients with anxiety score of above 43 were randomly assigned into two groups of aromatherapy and placebo groups. Fifteen minutes Before and then angiography, the physiologic parameter and anxiety of the patients were measured, and the intervention group sniffed three drops of essential oil of orange blossom for three minutes. Results: In the intervention group, there was no significant difference between the mean score of the manifest and hidden anxiety and the physiological indices before and after the intervention. The adjusted post-intervention values showed that systolic and diastolic blood pressure in the control group were significantly lower than intervention group (P<0.001). The mean reduction of systolic blood pressure in the intervention and control group was 3% and 13%, respectively. The mean diastolic blood pressure reduction was 2% vs 7% in the intervention and control group, respectively. Conclusion: This study revealed no significant effect of aromatherapy on anxiety of the patients undergoing angiography. Among physiologic parameter, systolic and diastolic blood pressure significantly reduced after intervention.

Abstract:

Stress and anxiety significantly impact the hypothalamic–pituitary axis, and in pregnancy, the subsequent maternal–fetal response can lead to poor outcomes. The objective of this study was to assess the association between psychosocial measures of pregnancy-specific anxiety and physiologic inflammatory responses. Specifically, to determine the effectiveness of the Mentors Offering Maternal Support (M-O-M-STM) program to reduce psychosocial anxiety and associated inflammatory response. In conjunction with measures of pregnancy-specific anxiety and depression, serum biomarkers (IL-2, IL-6, IL-10, IL1-B, TNF-α, CRH, CRP, and cortisol) were analyzed for each trimester throughout pregnancy. Results demonstrated that women receiving the M-O-M-STM intervention had longitudinally sustained lower TNF-α/IL-10 ratios than the control group, and it was significantly associated with psychosocial measures of anxiety, specifically for fears of labor and spouse/partner relationships. Additionally, the anxiety of spouse/partner relationships was significantly associated with IL-6/IL-10 ratios. The findings highlight the important counter-regulatory relationship between anti- and pro-inflammatory cytokines and provide insight into the distinct physiologic responses to pregnancy-specific anxiety with early prenatal intervention.

Abstract:

The role of individual differences in anxiety sensitivity was explored in a sample of 67 college-level music students. Individuals high in anxiety sensitivity report greater fear of bodily sensations. Although developed in research on panic disorder, anxiety sensitivity was hypothesized to predict performance anxiety. Anxiety sensitivity was found to predict performance anxiety and was a better predictor than trait anxiety. Overall, anxiety sensitivity was a better predictor of performance anxiety in women than men, and sensitivity to cognitive symptoms was a better predictor of performance anxiety than sensitivity to physiologic symptoms for both men and women. Gender differences emerged in the patterns of anxiety sensitivity, with men having stronger associations between fears of cognitive dyscontrol and performance anxiety than women, while women alone had associations between fears of cardiovascular and respiratory symptoms and performance anxiety. Those highest in anxiety sensitivity were found also to report less enjoyment while playing and more pain. Suggestions for future research are made, and implications for treatment programs are explored.

Abstract:

Objectives As specialists of the upper airway, otolaryngologists are at high risk for COVID-19 transmission. N95 and half-face respirator (HFR) masks are commonly worn, each with advantages in functionality and comfort. In this study, physiologic and psychological parameters of prolonged N95 vs HFR wear were compared. Study Design Prospective crossover cohort study. Setting Single academic tertiary care hospital. Methods A prospective crossover cohort study was performed. Healthy otolaryngology trainees and medical students (N = 23) participated and wore N95 and HFR masks continuously for 3 hours each on separate days. Various measures were analyzed: vitals, spirometry variables, scores on the State-Trait Anxiety Inventory and HIT-6 (Headache Impact Test–6), distress, and “difficulty being understood.” Results The average age was 26.3 years (SD, 3.42). There were no significant differences in vital signs and spirometry variables between N95 and HFR wear. N95 wear was associated with decreases in oxygen saturation of approximately 1.09% more than with HFRs (95% CI, 0.105-2.077). State-Trait Anxiety Inventory scores increased more with HFR wear when compared with mean changes with N95 wear (95% CI, 1.350-8.741). There were no significant differences in HIT-6 scores or distress levels between masks. The proportions of participants reporting difficulty being understood was significantly higher with HFRs. Conclusions Oxygen saturation decreases with prolonged N95 wear, but anxiety and difficulty being understood are greater with HFR wear. Although HFRs have less resistance to gas exchange, N95 respirators may produce less anxiety and distress in clinical situations. Further studies are warranted to evaluate the clinical significance of these differences. Level of Evidence 2.

Abstract:

BackgroundGiven the anxiety patients experience during angiography, evidence supporting the efficacy of music therapy during these angiographic procedures is potentially of clinical value.ObjectiveTo analyze the existing literature forthe use of music therapy during cerebral, coronary, and peripheral angiography to determine whether it improves patient anxiety levels, heart rate, and blood pressure during the procedure.MethodsPubMed, Embase, and Scopus were searched to identify studies of interest. Inclusion criteria included studies reporting using music therapy in either cerebral, coronary, or peripheral angiography. Studies focused on a pediatric population; animal studies and case reports were excluded. Participant demographics, interventions, and outcomes were collected by two study authors. Bias and study quality of randomized controlled trials (RCTs) were assessed using the Cochrane Risk of Bias Tool. Separate meta-analyses of the RCTs were performed to compare State Trait Anxiety Inventory (STAI), heart rate (HR), and systolic and diastolic blood pressure (SBP and DBP) in the music intervention group versus control group. Heterogeneity was determined by calculating I2 values, and a random-effects model was used when heterogeneity exceeded 50%.ResultsThe preprocedure to postprocedure improvement in STAI was significantly greater in the experimental group than the control group (p=0.004), while the decrease in HR, SBP, and DBP was not significant.ConclusionsRecorded music and/or music therapy in angiography significantly decreases patients’ anxiety levels, while it has little to no effect on HR and BP. This meta-analysis is limited by the relatively few RCTs published on this subject.PROSPERO registration numberCRD42018099103

Abstract:

Background To determine whether parental presence during induction of anesthesia is an effective preoperative behavioral intervention, a randomized controlled trial with children undergoing outpatient surgery was conducted. Methods Eighty-four children were randomly assigned to a parent-present or parent-absent group. Using multiple behavioral and physiologic measures of anxiety, the effect of the intervention on the children and their parents was assessed. Predictors for the response to the intervention were examined using multivariate linear regression analysis. Results When the intervention group (parent-present) was compared to the control group (parent-absent), overall there were no significant differences in any of the behavioral or physiologic measures of anxiety tested during induction of anesthesia. Using the child's serum cortisol concentration as the outcome, parental presence, the child's age and baseline temperament, and trait anxiety of the parent, were identified as predictors of the child's anxiety during induction. Analysis of variance demonstrated that three groups showed diminished cortisol concentrations with parental presence: children older than 4 yr (P = 0.001), children whose parent had a low trait anxiety (P = 0.02), and children who had a low baseline level of activity as assessed by temperament (P = 0.05). Conclusions Children who were older than 4 yr or those with a parent with a low trait anxiety or who had a low baseline level of activity/temperament benefited from parental presence during induction.

Abstract:

Lateral hypothalamic area (LHA) neurons expressing the neuropeptide orexin (OX) are implicated in obesity and anxio-depression. However, these neurons release OX as well as a host of other proteins that might contribute to normal physiology and disease states. We hypothesized that delta-like homolog 1 (DLK1), a protein reported to be co-expressed by all OX neurons, contributes to the regulation of energy balance and/or anxio-depression. Consistent with previous reports, we found that all rat OX neurons co-express DLK1. Yet, in mice and humans only a subset of OX neurons co-expressed DLK1. Since human OX-DLK1 distribution is more similar to mice than rats, mice are a comparable model to assess the human physiologic role of DLK1. We therefore used a viral lesion strategy to selectively delete DLK1 within the LHA of adult mice (DLK1Null) to reveal its role in body weight and behavior. Adult-onset DLK1 deletion had no impact on body weight or ingestive behavior. However, DLK1Null mice engaged in more locomotor activity than control mice and had decreased anxiety and depression measured via the elevated plus maze and forced swim tests. These data suggest that DLK1 expression via DLK1-expressing OX neurons primarily contributes to anxio-depression behaviors without impacting body weight.

Abstract:

ABSTRACT Background: Dentistry has made a remarkable progress in techniques, materials and technologies, however the anxiety of the child related to dental treatment still remains constant. Tell Show Do is the most common technique behaviour management of the child in the dental clinic since many years. Recently, many modifications of Tell Show Do technique have been researched and most of them provided an enhanced potential for the conventional technique research but were always individually compared to conventional technique. Aim: To evaluate the effectiveness of Tell Show Do technique in comparison with its 4 modifications Tell Play Do, Tell Play Do with Smart Phone Dentist Game, Tell Show Play Doh, Ask Tell Ask among 4-8 years old children during restorative treatment. Methodology: 150 children aged 4-8 years were randomly selected divided into 5 groups comprising of 30 patients each. Evaluation of anxiety was done using Physiologic-Pulse Rate, Facial Image Scale and Venham’s Anxiety Scale. Results: Except for Ask Tell Ask Group the anxiety level of the subjects decreased in all groups according to physiologic readings and facial image score. Anxiety Score decreased preoperatively to postoperatively in all groups except for Tell Play Do and Ask Tell Ask group according to venhams anxiety scale. Conclusion: Although Tell Show Do technique is most widely accepted and modified technique, due to changing scenarios of today’s children Tell Play Do, Tell Play Do with Smart Phone Dentist Game and Tell Show Play Doh are also showing encouraging results.

Abstract:

Over the past years self-tracking of physiological parameters has become increasingly common: more and more people are keeping track of aspects of their physiological state (e.g., heart rate, blood sugar, and blood pressure). To shed light on the possible effects of self-tracking of physiology, a study was conducted to test whether physiology feedback has acute effects on self-reported stress and the extent to which self-reported stress corresponds to physiological stress. In this study, participants executed several short tasks, while they were either shown visual feedback about their heart rate or not. Results show that self-reported stress is more in sync with heart rate for participants who received physiology feedback. Interactions between two personality factors (neuroticism and anxiety sensitivity) and feedback on the level of self-reported stress were found, indicating that while physiology feedback may be beneficial for individuals high in neuroticism, it may be detrimental for those high in anxiety sensitivity. Additional work is needed to establish how the results of this study may extend beyond immediate effects in a controlled lab setting, but our results do provide a first indication of how self-tracking of physiology may lead to better body awareness and how personality characteristics can help us predict which individuals are most likely to benefit from self-tracking of physiology.

Abstract:

Background Homelessness among youth is devastating, with high rates of substance use disorders and mental health comorbidity. Mindfulness-based interventions that include meditation and mindfulness skills training reduce stress and symptoms of anxiety or depression. However, engaging high-risk youth in interventions is challenging. Virtual reality is a more flexible platform for delivering meditation and may be appealing to youth. Objective The study objectives were to evaluate the feasibility of delivering virtual reality meditation and of collecting outcome measures, including anxiety and physiologic stress. Methods A sample of 30 youth experiencing homelessness was enrolled in the study. Youth were randomized to receive 10 minutes of one of three interventions: (1) virtual reality meditation, (2) audio meditation (through a web-based platform), or (3) virtual reality imagery of historical pictures and text. Subjects who consented to the study attended two research visits. The first visit collected survey measures of demographics, mental health, and substance use, and oriented subjects to the intervention platforms. The second visit (1-3 days later) delivered the intervention and collected pre and post outcome measures of anxiety and physiologic stress (salivary cortisol). Changes in anxiety and cortisol at the second visit were compared across groups using a linear regression model in which the primary analysis compared virtual reality meditation to audio meditation and secondary analyses compared virtual reality meditation to virtual reality imagery. Results Anxiety scores decreased in all groups, with a larger reduction among the virtual reality meditation group (difference=10.8) compared to the web-based meditation or virtual reality images groups (difference=5.8 and 5.0, respectively). After controlling for baseline values, there were no significant group differences in changes in anxiety scores or cortisol levels. In comparing virtual reality meditation and audio meditation, the effect size for anxiety was moderate (Cohen d=0.58) while the effect size for cortisol was small (Cohen d=0.08). Conclusions Preliminary results suggest that virtual reality meditation has a moderate benefit for anxiety but not physiologic stress. Future research is needed to confirm these results in a larger sample and to investigate whether the effects are sustained or increase with repeated use of virtual reality mediation. Virtual reality meditation appears feasible to deliver among homeless youth and merits further study.

Abstract:

BACKGROUND AND AIMS EngAGE: Community is a student-led Exercise Physiology service delivery model that provides accessible, enjoyable and socially engaged exercise programs for older adults to combat loneliness. We aimed to assess the impact of EngAGE: Community on social, psychological, and quality of life outcomes in community-dwelling older adults, and student development. METHODS EngAGE: Community was a 15-week telehealth group-exercise program that recruited community-dwelling older adults and student Exercise Physiology practitioners. Classes were supervised by an Accredited Exercise Physiologist. Each EngAGE session consisted of exercise, educational and community-developing activities. Participant survey outcomes for social and psychological health, and quality of life were collected online before and following the program. Student development outcomes were also collected online before and following the program. RESULTS Across four programs, 73 community participants and 15 student participants were recruited, providing 1042 community engagement hours and 900 student development hours. Of these, 45 community participants completed sufficient attendance for data inclusion, and 14 student datasets were included. Community participants reported significant improvements in social [UCLA Loneliness Scale (p=0.001), Social Anxiety and Phobias Scale (p=0.007)] and psychological health [Kessler-10 (p=0.03)], as well as quality of life [SF-12 (p=0.02) and Satisfaction with Life Scale (p=0.05)]. A subset of the population demonstrated significant improvements in lower (p<0.001) and upper body strength (p=0.003). Student practitioners reported significant improvements in Work Self-Efficacy (p=0.002), Confidence in Skills (p=0.02) and Work Readiness (p=0.03). Community participants (n=48) provided an 81-98% agree/strongly agree response to qualifying statements suggesting the program was enjoyable, educational, social, and beneficial for their wellbeing. The cost per practitioner contact minute for all EngAGE: Community rotations was calculated as $1.92 compared to $4.21 for usual care (45% saving). CONCLUSION EngAGE: Community is a viable and cost-effective telehealth strategy to improve older Australians social and psychological health while developing Exercise Physiology student practitioners.

Abstract:

Thought stopping is a therapy that can help stop disruptive thoughts from changing the thought process. This study aims to determaine the influence of thought stopping therapy on anxiety in the elderly facing the Covid 19 Pandemic in Elderly home . This study used quasi eksperimental design with pre- post test with control group. Responden were 70 people that devided into two group. They were 35 as intervention group that received thought stopping and 35 as control group that received nursing therapy of anxiety. Result showed anxiety in the intervention group decreased from moderate anxiety to mild anxiety and control group decreased still in the moderate anxiety. Thought stopping decreased physiologic, cognitive, behaviour and emotional responses of anxiety significantly (p value <0,05). thought stopping therapy was recommended as therapy to solve the anxiety at home elderly and community.

Abstract:

The relation between anxiety and cortical activity was compared in two samples of normal volunteers. One group was studied with the noninvasive xenon-133 inhalation technique for measuring cerebral blood flow (CBF) and the other with positron emission tomography (PET) using 18Flurodeoxyglucose (18FDG) for measuring cerebral metabolic rates (CMR) for glucose. The inhalation technique produced less anxiety than the PET procedure, and for low anxiety subjects, there was a linear increase in CBF with anxiety. For higher anxiety subjects, however, there was a linear decrease in CBF with increased anxiety. The PET group manifested a linear decrease in CMR with increased anxiety. The results indicate that anxiety can have systematic effects on cortical activity, and this should be taken into consideration when comparing data from different procedures. They also suggest a physiologic explanation of a fundamental behavioral law that stipulates a curvilinear, inverted-U relationship between anxiety and performance.

Abstract:

A substantial proportion of noncommunicable disease originates in habitual overconsumption of calories, which can lead to weight gain and obesity and attendant comorbidities. At the other end of the spectrum, the consequences of undernutrition in early life and at different stages of adult life can also have major impact on wellbeing and quality of life. To help address some of these issues, greater understanding is required of interactions with food and contemporary diets throughout the life course and at a number of different levels: physiological, metabolic, psychological, and emotional. Here we review the current literature on the effects of dietary manipulation on anxiety-like behaviour. This evidence, assembled from study of preclinical models of diet challenge from gestation to adult life, supports a role for diet in the important connections between psychology, physiology, and behaviour. Analogous processes in the human population in our current obesogenic environment are likely to contribute to individual and societal challenges in this area.

Abstract:

Novel anxiolytics notwithstanding, in the latest fifteen years there have been no major innovations in the treatment of anxiety disorders. Fascinating research is going on, but real breakthroughs will require adequate models of disease, based on the disordered physiology of each type of pathological anxiety. In this brief overview, we will address both the field of potential anxiolytics in 1997, and the development of new experimental models of anxiety disorders.

Abstract:

BackgroundChronic early trauma alters children's stress reactivity and increases the prevalence of anxiety disorders; yet the neuroendocrine and immune mechanisms underpinning this effect are not fully clear. Animal studies indicate that the mother's physiology and behavior mediate offspring stress in a system-specific manner, but few studies tested this external-regulatory maternal role in human children exposed to chronic stress.MethodsWe followed a unique cohort of children exposed to continuous wartime trauma (N= 177; exposed;N= 101, controls;N= 76). At 10 years, maternal and child's salivary immunoglobulin A (s-IgA) and oxytocin (OT), biomarkers of the immune and affiliation systems, were assayed, maternal and child relational behaviors observed, mother and child underwent psychiatric diagnosis, and child anxiety symptoms assessed.ResultsWar-exposed mothers had higher s-IgA, lower OT, more anxiety symptoms, and their parenting was characterized by reduced sensitivity. Exposed children showed higher s-IgA, more anxiety disorders and post traumatic stress disorder, and more anxiety symptoms. Path analysis model defined three pathways by which maternal physiology and behavior impacted child anxiety; (a) increasing maternal s-IgA, which led to increased child s-IgA, augmenting child anxiety; (b) reducing maternal OT, which linked with diminished child OT and social repertoire; and (c) increasing maternal anxiety, which directly impacted child anxiety.ConclusionsOur findings, the first to measure immune and affiliation biomarkers in mothers and children, detail their unique and joint effects on children's anxiety in response to stress; highlight the relations between chronic stress, immune activation, and anxiety in children; and describe how processes of biobehavioral synchrony shape children's long-term adaptation.

Abstract:

AbstractBehavioural anxiety tests in non-human animals are used for anxiolytic drug discovery, and to investigate the neurobiology of threat avoidance. Over the past decade, several of them were translated to humans with three clinically relevant goals: to assess potential efficacy of candidate treatments in healthy humans; to develop diagnostic tests or biomarkers; and to elucidate the pathophysiology of anxiety disorders. In this review, we scrutinise these promises and compare seven anxiety tests that are validated across species: five approach-avoidance conflict tests, unpredictable shock anticipation, and the social intrusion test in children. Regarding the first goal, three tests appear suitable for anxiolytic drug screening in humans. However, they have not become part of the drug development pipeline and achieving this may require independent confirmation of predictive validity and cost-effectiveness. Secondly, two tests have shown potential to measure clinically relevant individual differences, but their psychometric properties, predictive value, and clinical applicability need to be clarified. Finally, cross-species research has not yet revealed new evidence that the physiology of healthy human behaviour in anxiety tests relates to the physiology of anxiety symptoms in patients. To summarise, cross-species anxiety tests could be rendered useful for drug screening and for development of diagnostic instruments. Using these tests for aetiology research in healthy humans or animals needs to be queried and may turn out to be unrealistic.

Abstract:

Peculiarities of occurence of psychogenic disorders in children are explored, and efficiency of psychotherapy is estimated. In clinical picture of psychogenic disorders anxiety-depressive (59,0%), cerebroasthenic (61,5%) and phobic (8,6%) syndromes prevailed. In 34% of children increased level of anxiety was noted. In 87% of children low physiologic stress resistance was found. Use of psychotherapy in correction of psychogenic disorders was found to be effective. The performed analysis of psycho- traumatic effects makes it possible to recommend use of psychotherapeutic procedures adapted for the given age in combined therapy of psychogenic disorders.

Abstract:

In this article we are calling for an interlayered and cross-dimensional approach to understanding and working with anxiety, especially as manifested in English as an additional language (EAL) teaching and learning environments. We aim to understand the phenomenon of anxiety from the multidimensional perspectives of physiology, psychology, and philosophy; to introduce what we call the Triunal Model of Understanding Anxiety; and based on this new understanding, to suggest how teacher education may help teachers to notice and work with anxiety in teaching-learning environments. Given the scope of what we propose, this article with its limited space affords only an initial synopsis and model-building exercise.

Abstract:

The gut-brain-microbiota axis is increasingly recognized as an important regulator of intestinal physiology. Exposure to psychological stress causes activation of the hypothalamic-pituitary-adrenal (HPA) axis and causes altered intestinal barrier function, intestinal dysbiosis, and behavioral changes. The primary aim of this study was to determine whether the effects of psychological stress on intestinal physiology and behavior, including anxiety and memory, are mediated by the adaptive immune system. Furthermore, we wanted to determine whether treatment with probiotics would normalize these effects. Here we demonstrate that B and T cell-deficient Rag1 −/− mice displayed altered baseline behaviors, including memory and anxiety, accompanied by an overactive HPA axis, increased intestinal secretory state, dysbiosis, and decreased hippocampal c-Fos expression. Both local (intestinal physiology and microbiota) and central (behavioral and hippocampal c-Fos) changes were normalized by pretreatment with probiotics, indicating an overall benefit on health conferred by changes in the microbiota, independent of lymphocytes. Taken together, these findings indicate a role for adaptive immune cells in maintaining normal intestinal and brain health in mice and show that probiotics can overcome this immune-mediated deficit in the gut-brain-microbiota axis.

Abstract:

Objective: Optimal oral health is an essential component of good quality of life. However, this may be hindered by dental anxiety (DA), thereby, affecting the utilization of dental services. DA could be alleviated by pre-treatment information; however, the method of delivering this information is yet to be explored. It is, therefore, necessary to assess the modes of presenting pre-treatment information to ascertain the one with significant effect on DA. This will improve treatment outcomes and quality of life for individuals. Hence, the primary objective is to assess the effect of audiovisual and written forms of pre-treatment information on DA, while the secondary objective will compare the subjective and objective methods of assessing DA with psychometric anxiety scale (Index of Dental Anxiety and Fear (IDAF)-4C+) and salivary alpha-amylase respectively. Study design: Single-centred, single-blind, parallel-group, four-arm randomized clinical trial. Methods: The study will compare the effects of audiovisual and written forms of pre-treatment information on DA among adults. Patients 18 years and above scheduled for dental treatment will be screened for eligibility. Written informed consent will be sought before participation. Participants will be allocated randomly using block randomization, to the groups; G1: audiovisual and G2: a written form of pre-treatment information. At the visit, participants will complete the DA questionnaires (IDAF-4C+, Modified Dental Anxiety Scale and Visual Analogue Scale). Physiological anxiety-related changes of salivary alpha-amylase will be measured using a point-of-care kit (iPro oral fluid collector) at baseline, and 10 min after intervention. Furthermore, blood pressure will be taken at baseline and 20 min into the treatment. The mean changes of physiologic anxiety levels and 95% confidence intervals will be compared between the methods of pre-treatment information. Discussion: This study hopes to establish pre-treatment information as a method for reducing DA among the populace. Also, to assess the relationship between questionnaire-based and physiologic methods of assessing DA.

Abstract:

AbstractPurpose:The diagnosis of Postural Orthostatic Tachycardia syndrome traditionally involves orthostatic vitals evaluation. The Compensatory Reserve Index is a non-invasive, FDA-cleared algorithm that analyses photoplethysmogram waveforms in real time to trend subtle waveform features associated with varying degrees of central volume loss, from normovolemia to decompensation. We hypothesised that patients who met physiologic criteria for Postural Orthostatic Tachycardia syndrome would have greater changes in Compensatory Reserve Index with orthostatic vitals.Methods:Orthostatic vitals and Compensatory Reserve Index values were assessed in individuals previously diagnosed with Postural Orthostatic Tachycardia syndrome and healthy controls aged 12–21 years. Adolescents were grouped for comparison based on whether they met heart rate criteria for Postural Orthostatic Tachycardia syndrome (physiologic Postural Orthostatic Tachycardia syndrome).Results:Sixty-one patients were included. Eighteen percent of patients with an existing Postural Orthostatic Tachycardia syndrome diagnosis met heart rate criteria, and these patients had significantly greater supine to standing change in Compensatory Reserve Index (0.67 vs. 0.51; p<0.001). The optimal change in Compensatory Reserve Index for physiologic Postural Orthostatic Tachycardia syndrome was 0.60. Patients with physiologic Postural Orthostatic Tachycardia syndrome were more likely to report previous diagnoses of anxiety or depression (p = 0.054, 0.042).Conclusion:An accurate diagnosis of Postural Orthostatic Tachycardia syndrome may be confounded by related comorbidities. Only 18% (8/44) of previously diagnosed Postural Orthostatic Tachycardia syndrome patients met heart rate criteria. Findings support the utility of objective physiologic measures, such as the Compensatory Reserve Index, to more accurately identify patients with true autonomic dysfunction.

Abstract:

Abstract Examination of physiological coregulation among marital partners suggests a dynamic interplay between partner physiology. Further, attachment dimensions of anxiety and avoidance mediate this coregulation during conflict. This study examined the role of attachment and race in predicting physiological coregulation for mothers and their adult daughters during emotional discussions. A sample of 23 African American and 17 Caucasian mother-daughter pairs (aged 26 to 83) completed interview sessions and Relationships Questionnaires. Pairs engaged in discussions (neutral, conflict, happy), while monitoring heart rate. HR difference scores were computed between pairs (bps; 0 meant no difference). Multiple Regressions revealed attachment anxiety and avoidance predicted HR variation between pairs for the neutral and happy discussions, differently by racial group (F(7,33)=3.297, p < 0.01). For African American women, increased anxiety predicted increased HR variation during neutral and happy discussions, whereas for Caucasian women, increased avoidance predicted increased HR variation. However, during conflict anxiety singularly predicted increased HR covariation (b = 5.03, p = 0.01), for both groups. Low anxiety and low avoidance predicted physiological coregulation (lower HR variance between pairs). Increased anxious attachment predicted partner dysregulation (increased HR variation between pairs) across all 3 discussions, moderated by avoidance for the Caucasian women. Results suggest attachment plays a role in regulating physiology under emotional stress, and that there may be important cultural differences in this relationship. Further examination will explore the dynamic interplay between attachment and physiological coregulation across adulthood and later life.

Abstract:

Objective: This review will focus on aspects of the postconcussion syndrome (PCS), including accompanying symptomatology, neuropsychological changes, brain imaging studies and treatment. Method: In each topic area, those research studies resulting in the most interpretable data are reported. Since there is little research in some aspects of the PCS, some studies of limited merit are described, with their limitations outlined, in lieu of not reporting any study. The section on psychopharmacology largely consists of opinions of recognized clinicians, since there is almost no research on the psychopharmacology of PCS. Results: Mild traumatic brain injury is a relatively frequent occurrence which often results in the postconcussion syndrome (PCS), consisting of complaints of irritability, fatigue, headache, difficulty concentrating, dizziness, and memory problems. Anxiety and depression are also frequently present, especially later in its course. Although the PCS has often been thought to reflect a psychological response to injury, there is considerable recent evidence to suggest that it is primarily a physiologic disturbance. For most individuals, treatment consists primarily of education of the patient and his/her family, along with supportive counseling regarding emerging problems at work or at home. A subgroup of patients, however, may require psychopharmacologic intervention. Conclusion: More research is needed in all aspects of PCS, especially its neurophysiology and pharmacologic treatment. Relationships between neurophysiological changes and behavioral and neuropsychological changes are unknown. New imaging techniques, such as single-photon emission tomography, and positron emission tomography will likely play an important role in understanding the physiology of this disorder.

Abstract:

An interactive computer testing and record keeping system was implemented for a large self-paced anatomy and physiology course. This system including security procedures, is described and results of exploratory research axe presented on student preference for on-line testing, test anxiety, attitude and achievement. This required testing program included immediate feedback, second attempts, and retests. When correlates of achievement, test anxiety, and computer attitudes were investigated, we found that over time there was a slight reduction in realistic computer attitudes and a slight increase in general test anxiety. Students reported more facilitating anxiety with computer administered tests and more debilitating anxiety with paper and pencil tests. Strengths and weaknesses of such testing for faculty and for students is discussed. Suggestions are presented for properly integrating a computer testing program into a course.

Abstract:

This study examined the experience of performance anxiety in solo piano playing from the perspective of the participants. Research questions focusing on the following categories were addressed: (1) What does the experience of performance anxiety feel like to a solo pianist? (2) What are the ways in which performance anxiety manifests itself? A qualitative methodology was employed in this study. Six pianists on the faculties of southwestern colleges and universities were chosen selectively for participation. A survey questionnaire and an individual interview were used to collect data. The researcher analyzed the transcripts of the interviews, and codes were developed accordingly. The categories of research questions were used for the interpretation of the findings. The symptoms of performance anxiety manifested themselves through a combination of thought processes, feelings, and physiologic responses, activated by the perception of a threat by the performer. Negative thoughts and feelings dominated the experience of musical performance anxiety and undermined the self-confidence level of the performer. The identity of the performer was affected by how the individual viewed himself or herself and the individual’s perception of how others viewed him or her.

Auto-positive end expiratory pressure (auto-PEEP) is a physiologic event that is a recently recognized phenomenon common to mechanically ventilated patients. Auto-PEEP occurs when forces exist that limit expiration and the subsequent elimination of positive pressure from the lungs. If positive pressure is retained, a potential reduction in cardiac output and increase in complications from barotrauma arise. Because of possible physiologic problems associated with it, auto-PEEP can potentially interfere with weaning from mechanical ventilation. Nursing measures that can reduce the effect of auto-PEEP during weaning are centered on improving the inspiratory/expiratory flow patterns. These efforts include manipulating mechanical ventilator settings and reducing causes of increased respiratory rates (e.g., pain and anxiety). Since auto-PEEP was only recently identified as a potential impediment to weaning from mechanical ventilation, the nurse must be aware of the need to assess for the presence of auto-PEEP in these patients
