“…Acute stress has been found both to facilitate and to impair performance in a variety of contexts; however, complex cognitive processing and functions, where stressors occur peripherally to the primary task, are generally found to be impacted negatively by increased stress. This is particularly relevant to the surgical environment, where stress and stressors have been shown to adversely impact functions such as decision‐making and team performance. Studies have observed stress in the live operating theatre using a variety of methods , but limitations in ECG equipment and stress measurement methods have hindered research.…”

BackgroundStress has been shown to impact adversely on multiple facets critical to optimal performance. Advancements in wearable technology can reduce barriers to observing stress during surgery. This study aimed to investigate the association between acute intraoperative mental stress and technical surgical performance.MethodsContinuous electrocardiogram data for a single attending surgeon were captured during surgical procedures to obtain heart rate variability (HRV) measures that were used as a proxy for acute mental stress. Two different measures were used: root mean square of successive differences (RMSSD) and standard deviation of RR intervals (SDNN). Technical surgical performance was assessed on the Operating Room Black Box® platform using the Generic Error Rating Tool (GERT). Both HRV recording and procedure video recording were time‐stamped. Surgical procedures were fragmented to non‐overlapping intervals of 1, 2 and 5 min, and subjected to data analysis. An event was defined as any deviation that caused injury to the patient or posed a risk of harm.ResultsRates of events were significantly higher (47–66 per cent higher) in the higher stress quantiles than in the lower stress quantiles for all measured interval lengths using both proxy measures for acute mental stress. The strongest association was observed using 1‐min intervals with RMSSD as the HRV measure (P < 0·001).ConclusionThere is an association between measures of acute mental stress and worse technical surgical performance. Further study will help delineate the interdependence of these variables and identify triggers for increased stress levels to improve surgical safety.

Artificial neural networks (ANNs) are known to be a powerful tool for data analysis. They are used in social science, robotics, and neurophysiology for solving tasks of classification, forecasting, pattern recognition, etc. In neuroscience, ANNs allow the recognition of specific forms of brain activity from multichannel EEG or MEG data. This makes the ANN an efficient computational core for brain-machine systems. However, despite significant achievements of artificial intelligence in recognition and classification of well-reproducible patterns of neural activity, the use of ANNs for recognition and classification of patterns in neural networks still requires additional attention, especially in ambiguous situations. According to this, in this research, we demonstrate the efficiency of application of the ANN for classification of human MEG trials corresponding to the perception of bistable visual stimuli with different degrees of ambiguity. We show that along with classification of brain states associated with multistable image interpretations, in the case of significant ambiguity, the ANN can detect an uncertain state when the observer doubts about the image interpretation. With the obtained results, we describe the possible application of ANNs for detection of bistable brain activity associated with difficulties in the decision-making process.

“…The TSST is comprised of a mock job interview in front of judges and a mental arithmetic task (serially subtracting 13 from 1022). The procedure has been described in detail elsewhere . The only difference between the current study and the previous one was that the preparation period was extended from 3 to 5 minutes in duration.…”

Addictions, both substance and behavioral, have been conceptualized as involving similar biopsychosocial processes with different opportunistic expressions. A maladaptive stress response in combination with craving or urges to engage in the addictive behavior may be among the underlying factors common to behavioral and substance addictions. The current study compared the neuroendocrine (cortisol) and subjective responses to stress of gamblers and smokers to healthy controls. We assessed if participants responded differently to smoking or gambling cues before and after a psychosocial stressor. To this end, the subjective urges/cravings of all participants were measured in response to smoking or gambling cues versus neutral cues, once under normal conditions and again after exposure to a stressor. Salivary cortisol was measured prior to, immediately following, and 10 minutes after conclusion of the stressor. Smokers and gamblers showed a similar blunted cortisol response to the acute stressor that differed from the control group's response. Following a stressor, subjective craving in smokers increased whereas gamblers' urges decreased. In smokers, a blunted cortisol and subjective stress response were related to increased urges. In contrast, for gamblers, changes in cortisol levels were unrelated to urges, and higher subjective stress was associated with decreased urges. In conclusion, individuals with a substance and a behavioral addiction share common patterns of reactivity to stress. However, while the stressor enhanced cue-related craving in smokers, it generally had the opposite effect on gamblers. Further research is necessary to elucidate the complicated patterns of similarities and differences that underlie substance and behavioral addictions.
