Drugs of abuse are widely known to worsen mental health problems, but this relationship may not be a simple causational one. Whether or not a person is susceptible to the negative effects of drugs of abuse may not only be determined by their addictive properties, but also the users’ chronotype, which determines their daily activity patterns. The present study investigates the relationship between chronotype, drug use and mental health problems in a cross-sectional community sample. Participants (n = 209) completed a selection of questionnaires online, including the Munich Chronotype Questionnaire, the Depression Anxiety Stress Scale, the Alcohol Use Disorder Identification Test, the Cannabis Use Disorder Identification Test and the Fagerström Test for Nicotine Dependence. We conducted multiple regression models to determine relationships between participants’ chronotype and their reported mental health symptoms and then estimated mediation models to investigate the extent to which their drug consumption accounted for the identified associations. Chronotype was significantly associated with participants’ overall mental health (β = 0.16, p = 0.022) and their anxiety levels (β = 0.18, p = 0.009) but not with levels of depression or stress. However, both relationships were fully mediated by participants’ overall drug consumption. Thus, late chronotypes, so-called “night owls”, not only use more drugs but consequently have an increased risk for developing anxiety and deteriorating mental health status. This group may be particularly vulnerable to the negative psychological effects of drugs. Our results point toward the importance of considering chronotype in designing preventative and therapeutic innovations, specifically for anxiety, which at present has been largely neglected.

In our study, the aim was to evaluate the effects of preoperative anxiety measured by Spielberger’s State-Trait Anxiety Inventory-State (STAI-S) and State-Trait Inventory-Trait (STAI-T) scores on intraoperative hemodynamic stability, drug consumption and recovery in patients who underwent spinal surgery with neurophysiological monitoring and total intravenous anesthesia with bispectral index (BIS) monitoring, without the use of muscle relaxants. Eighty patients with planned spinal surgery and neurophysiological monitoring were included in this prospective observational study. Anxiety scores were recorded by applying Spielberger’s STAI-T and STAI-S scoring questionnaires to all patients included in the study 1 hour before the operation. Age, gender and American Society of Anesthesiologists (ASA) scores of the patients who were taken to the operating table without premedication were recorded. Before anesthesia induction, standard monitoring including electrocardiography (ECG), noninvasive blood pressure, peripheral oxygen saturation (SpO2), BIS was applied. The correlation between STAI-T and STAI-S scores with demographic characteristics of patients, preoperative, post-induction, 5th minute, 10th minute, 30th minute, 50th minute, 70th minute, 90th minute heart rate (HR), mean arterial pressure (MAP), SpO2, operation time, recovery time, and total amount of propofol and remifentanil used during the operation were evaluated statistically. A significant negative correlation was observed between STAI-S anxiety scoring and age (p < 0.05). A significant positive correlation was found between the total amount of remifentanil and propofol used with the STAI-S score (p < 0.05). Significant positive correlations were observed between the STAI-S score and the HR value preoperatively, and in the 5th, 30th, 50th, 70th, and 90th minutes (p < 0.05). Our study showed that preoperative anxiety increases intraoperative drug consumption and heart rate. It is of great importance to keep the amount of intraoperative medication at optimal levels, to measure preoperative anxiety, and to eliminate it with multimodal treatments, especially for the accurate detection of neurological damage in patients with neurophysiological monitoring.

Background: As the majority of studies examining mental health during the pandemic are cross-sectional, little is known about the changes in mental health during the pandemic, especially in university students. Most studies indicate a worsening of mental health conditions. This study aimed to evaluate the mental health status of German university students during the third wave of the pandemic in 2021 and to compare the results to a sample of a congruent cross-sectional study from 2020.Methods: Two cross-sectional and anonymous online surveys among university students were conducted (first survey: July-August 2020, N = 3,382; second survey: March-April 2021, N = 5,642). Mental health status was assessed with standardized measures (depressive symptoms, alcohol and drug consumption, and eating disorder symptoms), and social and emotional aspects of the COVID-19 pandemic were assessed. In addition to descriptive statistics and group comparisons of the two survey samples from 2020 and 2021, respectively, risk and protective factors related to mental health were analyzed.Results: There were significant differences in severities of depressive symptoms and alcohol and drug consumption between the two online surveys from 2020 and 2021. Findings suggest an increase in the severity of depressive symptoms as well as alcohol and drug consumption. Significantly more respondents reported suicidal ideation in the survey from 2021. Lower self-efficacy, less social support and lower resilience as well as higher perceived stress and more loneliness were reported by the participants of the survey from 2021 compared to 2020. Regarding factors predicting mental health symptoms, being female was a positive predictor for hazardous alcohol use and anorexia nervosa in comparison to men. Further, younger age, being diverse, higher perceived stress and loneliness were positive predictors for all mental health outcomes.Conclusion: This study reveals an increase in severities of depressive symptoms, including suicidal ideation, drug and alcohol consumption among students. Being diverse, younger age, higher perceived stress and loneliness were mutual risk factors for higher depressive and eating disorder symptoms as well as alcohol consumption. Universities and health care policy should recognize and address mental health issues of young adults during ongoing times of crisis and invest in easy-to-access interventions.

Although rodents have a well-structured vocal form of communication, like humans and non-human primates, there is, to date, no evidence for a vocal signature in the well-known 50- and 22-kHz ultrasonic vocalizations (USVs) emitted by rats. Here, we show that rats can recognize the identity of the USV emitter since they choose to preferentially self-administer playback of 50-kHz USVs emitted by a stranger rat over those of their cagemate. In a second experiment, we show that only stranger, but not familiar, 50-kHz USVs reduce cocaine self-administration. Finally, to study the neurobiological substrate of these processes, we have shown that subthalamic nucleus (STN)-lesioned rats did not lever press much for any USV playback, whatever their emotional valence, nor did they seem able to differentiate familiar from stranger peer. Advocating for the existence of a vocal signature in rats, these results highlight the importance of ultrasonic communication in the socio-affective influence of behaviour, such as the influence of proximal social factors on drug consumption and confirm the role of the STN on this influence.

UNSTRUCTURED Aims: Virtual reality Hypnosis (VRH) has been used successfully in different clinical settings to treat anxiety and the sensation of pain. We aimed to investigate the feasibility and safety of VRH in patients undergoing electrophysiology and stimulation procedures under conscious sedation. Methods: During a two-month period, VRH support was proposed to patients undergoing interventions. Data were compared with a control group (n=61) enrolled during the following three-month period. In the intervention group (n=25), the dedicated VR hypnosis programme was projected during the procedure. In both groups, pain and comfort were measured at the end of the procedure and at discharge, using visual analogue scales (VASs; 0-10). Results: Baseline characteristics were comparable in both groups. There was no difference in procedure duration (46 (±29) vs 56 (±32) min, p=0,18) nor in hypnotic / antalgic consumption (1.95 (±1.44) vs 2.00 (±1.22) mg, p=0,83 and 3.78 (±2.87) vs 3.58 (±2.48) μg, p=0,9) for the control and VR groups respectively. In a multivariate analysis, the use of VR was independently associated with lower comfort during the procedure, assessed by post-operative VAS (OR 15.00 (IC95%4.77;47.16), p<0.01). There was no influence of VR use on pain or drug consumption. Conclusions: In our experience, VR hypnosis in the EP lab doesn’t improve comfort during the procedure, compared to conventional human care. It has no influence on pain or drug consumption.
