Cortisol Awakening Reaction and Anxiety in Depressed Coronary Artery Disease Patients

Disturbances of HPA axis functioning as represented by cortisol awakening reaction (CAR) belong to the mediating pathways linking psychosocial distress and cardiovascular risk. Both depression and anxiety have been confirmed as independent risk factors for coronary artery disease (CAD). However, data on anxiety and cortisol output in CAD patients are scarce. Based on previous data, we hypothesized that anxiety would be associated with higher cortisol output and a more pronounced morning increase in moderately depressed CAD patients. 77 patients (60 y, 79% male) underwent saliva sampling (+0, +30, +45, +60 min after awakening, midday and late-night sample). Anxiety was measured using the Hospital Anxiety and Depression Scale (HADS) and patients were grouped into anxious versus non anxious subjects based upon the recommended score (≥11). A repeated measures ANOVA yielded a significant time and quadratic time effect referring to the typical CAR. Anxious patients showed a significantly steeper 30 min increase, higher AUCi, lower waking and late-night cortisol levels. The steeper cortisol increase in the anxious group is in line with previous data and may be interpreted as a biological substrate of affect regulation. The lower basal and late-night levels coupled with greater AUCi mirror a more dynamic reactivity pattern compared to depressed subjects without anxiety.

Heart rate variability change during a stressful cognitive task in individuals with anxiety and control participants

Background Individuals suffering from an anxiety disorder are characterized by chronically low heart rate variability (HRV) compared to healthy individuals during resting state conditions. However, when examining HRV and HR in response to a stressor, mixed results have been obtained when comparing anxious and non-anxious groups. Methods The primary aim of the present study was to investigate HRV and HR responding in 26 clinically anxious and 14 control individuals before, during and after a stressful working memory task. Results Results indicate no between-group differences in HRV and HR at baseline. When starting the working memory task, the control group decreased significantly in HRV and the anxious group did not differ substantially in their change pattern from baseline to the start of the stressor. Finally, during the recovery phase of the working memory task, the clinically anxious and control individuals did not differ in their HFV or HR response compared to baseline. Conclusions From a clinical perspective, the results suggest that screening for the presence of anxiety disorders may help to identify patients with impaired HRV and HR functioning and to intervene on these important patient characteristics early in the treatment process.

Stress Makes the Difference: Social Stress and Social Anxiety in Decision-Making Under Uncertainty

Stress and anxiety can both influence risk-taking in decision-making. While stress typically increases risk-taking, anxiety often leads to risk-averse choices. Few studies have examined both stress and anxiety in a single paradigm to assess risk-averse choices. We therefore set out to examine emotional decision-making under stress in socially anxious participants. In our study, individuals (N = 87) high or low in social anxiety completed an expanded variation of the Balloon Analogue Risk Task (BART). While inflating a balloon to a larger degree is rewarded, a possible explosion leads to (a) a loss of money and (b) it is followed by an emotional picture (i.e., a calm vs. an angry face). To induce stress before this task, participants were told that they would have to deliver a speech. We operationalized risk-taking by the number of pumps during inflation and its functionality by the amount of monetary gain. In addition, response times were recorded as an index of decisional conflict. Without the stressor, high socially anxious compared to low socially anxious participants did not differ in any of the dependent variables. However, under stress, the low socially anxious group took more risk and earned more money, while high socially anxious individuals remained more cautious and did not change their risk-taking under social stress. Overall, high socially anxious individuals made their decisions more hesitantly compared to low socially anxious individuals. Unexpectedly, there were no main effects or interactions with the valence of the emotional faces. This data shows that stress affects socially anxious individuals differently: in low socially anxious individuals stress fosters risk-taking, whereas high socially anxious individuals did not alter their behavior and remained risk-averse. The novel eBART is a promising research tool to examine the specific factors that influence decision-making.

Depressed mood and anxiety as risk factors for hypertensive disorders of pregnancy: a systematic review and meta-analysis

BackgroundPsychosocial factors have been implicated as both a cause and consequence of hypertension in the general population but are less understood in relation to hypertensive disorders of pregnancy (HDP). The aims of this review were to (1) synthesize the existing literature examining associations between depression and/or anxiety in pregnancy and HDP and (2) assess if depression and/or anxiety in early pregnancy was a risk factor for HDP.MethodsA comprehensive search of Medline, Embase, CINAHL, and PsycINFO was conducted from inception to March 2020 using terms related to ‘pregnancy’, ‘anxiety’, ‘depression’, and ‘hypertensive disorders’. English-language cohort and case-control studies were included if they reported: (a) the presence or absence of clinically significant symptoms of depression/anxiety, or a medical record diagnosis of depression or an anxiety disorder in pregnancy; (b) diagnosis of HDP; and/or (c) data comparing the depressed/anxious group to the non-depressed/anxious group on HDP. Data related to depression/anxiety, HDP, study characteristics, and aspects related to study quality were extracted independently by two reviewers. Random-effects meta-analyses of estimated pooled relative risks (RRs) were conducted for depression/anxiety in pregnancy and HDP.ResultsIn total, 6291 citations were retrieved, and 44 studies were included across 61.2 million pregnancies. Depression and/or anxiety were associated with HDP [RR = 1.39; 95% confidence interval (CI) 1.25–1.54].ConclusionsWhen measurement of anxiety or depression preceded diagnosis of hypertension, the association remained (RR = 1.27; 95% CI 1.07–1.50). Women experiencing depression or anxiety in pregnancy have an increased prevalence of HDP compared to their non-depressed or non-anxious counterparts.

The Effect of Preoperative Anxiety Level on Mean Platelet Volume and Propofol Consumption

Background: The mean platelet volume (MPV) is an important indicator of platelet function with large platelets showing higher enzymatic and metabolic activity than other platelets. There can be a relationship between increased platelet activity and anxiety and depression. Our primary hypothesis was that patients with high anxiety scores would have higher MPV, and the secondary hypothesis was that propofol induction time and total propofol consumption within the first 30 min of surgery would be higher in patients with higher anxiety scores. Methods: The Beck Anxiety Inventory (BAI) was administered to the participating patients one day before surgery to evaluate the level of anxiety. Based on the scores from the BAI, 40 patients with an anxiety score of <8 were assigned to the non-anxious group (Group NA) and 40 patients with an anxiety score of ³8 were assigned to the anxious group (Group A). At the anesthesia induction the mean time to achieve an entropy value below 60 (T1) was recorded. The total intraoperative propofol consumption within the first 30 min was recorded. Results: There was a statistically significant difference between the groups in terms of preoperative MPV and demographic data, including age and sex. The mean total propofol consumption at 30 min after induction in the groups was statistically significant. The cut-off value for MPV was calculated as 9.65. Conclusions: The preoperative MPV values and propofol consumption at 30 minutes among patients with high preoperative anxiety scores were high. We suggest that MPV is helpful in the clinical practice in predicting the amount of anesthetic agents required for the induction of anesthesia.

The Relationship between Anxiety and Immunity in Pediatric Oncology Patients

Background: Pediatric onco-hematology is not a frequently encountered medical specialty, and it influences everyday life, basic activities, and the immune system, mostly through psychosocial changes, which may affect every individual and their families differently. Anxiety is the most frequently encountered mental health disorder occurring during childhood and adolescence. The effect of stress and anxiety on the immune system is suggested by the fact that stress hormones elevate proinflammatory cytokines and subsequently lower the anti-inflammatory response. Objective: Our main objective was to analyze the relationship between anxiety disturbance and cytokine levels in oncologic pediatric patients from Târgu Mureș in order to answer the following question: does anxiety influence immunity? Material and methods: After testing pediatric oncology patients from the Pediatrics Clinic no. 2 of Târgu Mureș, Romania with the SCARED child test, we took blood samples from each participant. IL-6, IL-10, IL-1β, IL-12p40 and TNF-α levels were evaluated with a Human Cytokine Magnetic Panel using the xMAP technique on Flexmap 3D platform (Luminex Corporation, Austin, USA). C-reactive protein levels were determined with the BN Pro Spec nephelometer with CardioPhase hsCRP (Siemens Healthcare Diagnostics, GmbH, Marburg, Germany) reagent. Results: The 46 pediatric oncology patients had 6 main diagnostic groups, the most frequent pathology was acute leukemia (58.7%) followed by malignant solid tumors (21.74%) and lymphomas (6.52%). In the anxious group (45.65%) we observed 4 of the 5 studied anxiety types: panic disorder, separation, social, and generalized anxiety. We measured the cytokine levels of all the participants from the two main groups: anxious/non-anxious. Statistical analysis (linear regression) showed statistically significant positive correlations in the anxious group related to the IL-1β and IL-6, a moderate/weak correlation related to IL-12p40, as well as a negative moderate correlation between IL-10 values in the anxious group and a positive trend in the non-anxious group. Conclusions: Psycho-oncology is a relatively young specialty with few studies in the last two decades. IL-1β, IL-6, and TNF-α present high levels in anxious patients, while IL-10 and IL-12p40 have low serum levels in mental disorders. C-reactive protein levels are not influenced by anxiety.

Persistent (Anxiety and Depression) Affected Academic Achievement and Absenteeism in Nursing Students

Background:Anxiety and depression are common among nursing students due to different factors. When they are minimal and not persistent, they work as stimuli for good achievement. However, when they are high or persistent they have negative consequences (i.e.low academic achievement and higher absenteeism rates).Objective:The purpose of this study was to check the effect of persistent anxiety and depression on nursing student academic achievement and absenteeism rate.Methods:A prospective observational correlational design with a convenience sample of 170 students enrolled in the undergraduate and graduate programs-college of nursing at a private university in Amman, Jordan. Anxiety and depression were measured twice at the beginning of the semester and then two months later by Hospital Anxiety and Depression Scale. Data regarding grade point average, number of absenteeism and the gender of the students; were collected from the electronic system of the university.Results:Persistently anxious group has lower grade point average than persistently non-anxious group (mean [SD], 64.1 [13.8]vs. 73.1 [12.3], P< .001). Moreover, they have higher absenteeism rate than persistently non-anxious group (7.62 [5.7]vs. 4.0 [3.4], P< .001) and higher than transiently anxious group (7.62 [5.7]vs. 4.7 [4.6], P< .05). Persistently depressed group has lower grade point average than persistently non-depressed group (64.0 [13.8]vs. 73.2 [13.0], P< .001) and lower than transiently depressed (64.0 [13.8]vs. 71.7 [10.6], P< .01).Conclusion:Nursing administrators should search for the underlying causes for these negative emotions. Furthermore, setting strategies to control these negative emotions is highly recommended.

Role of Colors in Pediatric Dental Practices

Objective: This study evaluated the association between colors and emotions in a pediatric dental population. Study design: In this randomized cross-sectional study, 100 children aged 6–12 years were categorized as non-anxious and anxious using Corah's Dental Anxiety Scale–Revised. They were then instructed to color two cartoon faces, one depicting happiness emotion and the other, sadness, with any of six colors provided. Data obtained were statistically analyzed. Results: The mean Corah's Dental Anxiety scores were 11.7 and 4.97 for the anxious and non-anxious children, respectively. Both groups expressed the highest preference for the color yellow for happiness emotion. No significant differences were observed between color choices in either group (p&gt;0.05), except for black which was not chosen by any child for happiness (p&lt;0.005). Children in both groups significantly preferred red for sadness emotion. No significant differences were observed between color choices in the anxious group (p&gt;0.05). In the non-anxious group, yellow assumed significant preference over green (p&lt;0.05). Conclusions: Yellow was the most-preferred color and black, the least-preferred, for happiness emotion, whereas, for sadness emotion, red and green were the most- and least-preferred colors, respectively. Color preference was not affected by the presence of dental anxiety.
