Purpose Among other non-motor symptoms, theory of mind (ToM), the ability to recognize, understand and infer others’ mental states, beliefs, intents and wishes, has been shown to deteriorate during the course of Parkinson’s disease (PD). It has been speculated that ToM impairments could be related to cognitive deficits in PD. However, the current state of literature suggests that there is heterogeneity regarding the involvement of cognitive functioning in the relationship of PD and ToM. The study aimed to measure affective ToM abilities and cognitive performance in a sample of PD patients, to explore the link between affective ToM abilities and cognitive status, and to examine the impact of PD on affective ToM through the mediator effect of cognitive performance. Patients and methods Sixty-five patients diagnosed with idiopathic PD and 51 healthy controls matched for age, gender and educational level completed a visual affective ToM task (Reading the Mind in the Eyes – RMET), cognitive performance was evaluated with Montreal Cognitive Assessment, and psychiatric symptoms were measured with BPRS-E (Brief Psychiatric Rating Scale). Results Affective ToM abilities were preserved in early PD patients, declining as the disease progressed. Deficits in cognitive functioning predicted deficiencies in affective ToM. Although attention (AT), executive functions (EF) and visuospatial abilities (VSA) together mediated the relationship between PD and affective ToM, only VSA impairment had a specific negative impact on affective ToM. Moreover, 41% of the total effect of attention and executive functions on affective ToM was mediated by visuospatial skills. Conclusion Cognitive performance may have an impact on the relationship between PD and affective ToM through the involvement of VSA. The influence of AT and EF in this relationship appears to be also exerted by PD patients’ VSA.

Patients with severe COVID-19 experience high-stress levels and thus are at risk for developing acute stress disorder (ASD) and/or post-traumatic stress disorder (PTSD). The present study aims to search for correlations between psychiatric response to stress and coping strategies among individuals with acute vs. remitted COVID-19. Ninety subjects with COVID-19 were included in the study, divided into two samples by disease category. Our focus was analysing the perceived stress intensity according to NSESSS and PCL-C-17 scales, and coping strategies with COPE-60. High NSESSS scores were found in 40% of acute patients, and 15.6% of remitted patients had high PCL-C-17 scores fulfilling the criteria for PTSD. We found a negative correlation between stress level and disease category. Acute patients used significantly more engagement and emotion-focused coping methods, but less disengagement types of coping than patients in the remitted phase. Remitted patients under high stress levels are prone to use disengagement and emotion-focused coping strategies. In conclusion, remitted COVID-19 patients experience lower levels of stress and use less emotion-focused strategies, except among those who developed PTSD post-COVID-19 infection, presenting with high-stress levels and using more disengagement and emotion-focused types of coping strategies.

Background Antipsychotic medication, stress, gender, and age are factors that influence prolactin levels in patients with psychosis. The aim of the study was to investigate the level of prolactin response to antipsychotic treatment in acute patients, taking into account the total duration of psychosis. Methods and findings The study was conducted on 170 acute patients with schizophrenia spectrum disorders and bipolar disorder. Subjects were divided into three subgroups according to the duration of the psychosis (less than 5 years, between 5 and 10 years and more than 10 years of disorder duration). The initial prolactin response under antipsychotic treatment was measured, while the severity of the psychiatric symptoms was assessed with the BPRS (Brief Psychiatric Rating Scale). Hyperprolactinemia was found in 120 (70.6%) patients, amongst which 80 (66.7%) were females and 40 (33.3%) were males. The average increase in prolactinemia was 2.46 times the maximum value in women, and 1.59 times in men. Gender (β = 0.27, p<0.0001), type of antipsychotic medication according to potency of inducing hyperprolactinemia (β =-0.23, p<0.003), and the duration of psychosis over 10 years (β =-0.15, p = 0.04) significantly predicted prolactin levels, when age, diagnosis, antipsychotic category (conventional/atypical/combinations of antipsychotics), and BPRS total scores were controlled for. Conclusions and relevance Prolactin levels in patients treated with antipsychotic medication appeared to depend on patients' gender, on the type of antipsychotic medication according to potency of inducing hyperprolactinemia, and on the duration of the psychosis. An increase in prolactin levels was associated with female gender, while the use of prolactin sparing antipsychotics and a duration of psychosis over 10 years were associated with lower prolactin levels.

PurposeMedical students’ personality traits, emotion regulation strategies, and empathic behavior are considered powerful predictors for their future achievements, professional adjustment, and mental strength. Coping strategies such as “self-blame,” “rumination,” “catastrophizing,” “blaming others,” lack of empathy, decreased emotion recognition abilities, and neuroticism are maladaptive and, thus, less desirable traits in medical professionals. The purpose of the study was to comparatively assess and find potential correlations between personality traits, empathy levels, emotion recognition abilities, and cognitive emotion regulation strategies of three medical student samples: general medicine (GM), dental medicine (DM), and general nursing (GN) students.Patients and methodsThis cross-sectional comparative study was conducted throughout the second semester of 2017, during Psychiatry class, on 306 medical undergraduates of the “Victor Babes” University of Medicine and Pharmacy, Timisoara, Romania. Personality was assessed by using Neuroticism–Extraversion–Openness to Experience Five-Factor Inventory (NEO-FFI). Cognitive emotion regulation strategies were identified using the Cognitive Emotion Regulation Questionnaire (CERQ). Empathy quotient (EQ) was used to measure empathy levels. Emotion recognition abilities were evaluated with the Reading the Mind in the Eyes test (RMET).ResultsGM students scored significantly higher than both DM and GN students in blaming others (CERQ) and significantly higher than GN students in “neuroticism” (NEO-FFI). GM and DM students obtained significantly lower scores than their GN colleagues in “agreeableness” (NEO-FFI) and empathy (EQ). Compared to DM students, GN students gave significantly more correct answers in RMET. Neuroticism was associated with less efficient coping mechanisms (self-blame, rumination, catastrophizing, blaming others) and lower empathy scores. Empathy correlated negatively with blaming others and was positively associated with agreeableness and emotion recognition abilities.ConclusionThe differences found between the student samples can be consequences of several overlapping factors. Certain personality traits may predispose individuals to maladaptive coping responses, increased vulnerability to stress, and lower empathy levels. The results of this study can be viewed as baseline data for future, more comprehensive, longitudinal analyses.

PurposeThis research article assesses the cardiovascular impact of long-term injectable antipsychotic therapy on patients diagnosed with schizophrenia spectrum disorders. In our study, we attempted to quantify the potential causes of cardiovascular damage, assess cardiovascular parameters, and correlate them with the time elapsed from the onset of the psychosis until the initiation of injectable antipsychotic therapy, as well as the duration of long-acting therapy, and finally, to compare two of the most utilized long-acting injectable (LAI) medications (olanzapine vs risperidone).Patients and methodsThis cross-sectional study recruited 64 patients of 2 outpatient clinics undergoing treatment with LAI antipsychotics for schizophrenic spectrum disorder. The study reports outpatients’ clinical data, laboratory blood sample findings, routine echocardiography, as well as speckle tracking echocardiography.ResultsAmong patients with longer durations of pre-long-acting antipsychotic treatment, body mass indices, mitral velocity wave values (E and A waves), and the global longitudinal strain (GLS) measurements significantly correlated with patients’ myocardial contractility. The study also found that GLS was significantly lower in the group in which pre-LAI duration was prolonged, and was not influenced by the duration of LAI treatment. Furthermore, patients receiving olanzapine showed significantly improved myocardial contractility as measured by the aforementioned parameters, in comparison with patients treated with risperidone.ConclusionThe results of our study indicate that patients suffering from schizophrenia and who are left untreated or poorly treated for a longer period of time may develop myocardial impairment. The changes may be both secondary to a high prevalence of cardiovascular risk factors and may also be generated by the disease per se. The group who received olanzapine demonstrated improved results for a longer period of time without proper medication.
