RESUMEN

ABSTRACT: According to recent studies, the growing consumption of Internet pornography mainly in male population becomes an increasing problem, which is closely linked to compulsive sexual behavior. Some findings also suggest that Internet pornography consumption might represent a defense mechanism against excessive stress, which enables to cope with stressful events, helps in mood regulation, and decreases depression and anxiety. Users of online pornography involved in these activities also reported that their self-exposition to pornographic material may create guilty feelings and internal conflict in themselves with respect to their own "involuntary" sexual behavior, which suggest that psychosocial stress and possibly traumatic experiences may play a significant role in Internet pornography addiction. Taken together, these findings show that stressful experiences, anxiety, and depression are strongly related to pornography consumption. In addition, conflicting emotional experiences as well as identity problems significantly increase vulnerability to addictive sexual behavior and pornography consumption.

RESUMEN

BACKGROUND There is a high prevalence of cognitive and socioemotional dysfunction in very low birth weight (VLBW <1500 g) and extremely low birth weight (ELBW <1000 g) children. This study from the Czech Republic aimed to compare the cognitive and socioemotional development at 5 and 9 years of age of children born with VLBW/ELBW with children born with normal birth weight (NBW ≥2500 g). MATERIAL AND METHODS The clinical group consisted of 118 VLBW/ELBW children and the control group consisted of 101 children with NBW at ages 5 to 9 years. The research battery included selected subscales from the Intelligence and Development Scales (IDS), A Developmental Neuropsychological Assessment - second edition (NEPSY-II), and the Behavior Rating Inventory of Executive Function (BRIEF). Data were analyzed using STATA IC v. 15 software and G*Power (descriptive statistic, analysis of variance (ANOVA), correlations, multivariate analysis of variance - MANOVA, post hoc power analysis). RESULTS We found a statistically significant difference in cognitive and socioemotional development between children with VLBW/ELBW and those with NBW. The average intelligence quotient (IQ) of VLBW/ELBW children was 96.38, while that of NBW children was 12.98 points higher (P<0.001). NBW children achieved better results on all subtests of the IDS (P<0.001) as well as in affect recognition (P<0.001). All results for both groups were within normal range. Parents of VLBW/ELBW children did not recognize impaired executive functioning (P=0.494). CONCLUSIONS This study has shown significant cognitive and socioemotional deficit in children born with VLBW and ELBW when evaluated at 5 and 9 years of age.

RESUMEN

The psychological consequences of trauma related to the Holocaust have been primarily studied in samples derived from Israel, North America, and Western Europe. Few studies have examined postcommunist countries in Central and Eastern Europe. The present study focused on three generations living in the Czech Republic and Slovakia after World War II (WWII): Holocaust survivors (71-95 years of age), their children (30-73 years of age), and their grandchildren (15-48 years of age). We compared scores on measures of posttraumatic stress symptoms (PTSS; the Posttraumatic Stress Disorder Checklist-Civilian Version) and posttraumatic growth (PTG; the Posttraumatic Growth Inventory) derived from three focal samples with scores from age-matched comparison participants. Higher PTSS scores emerged for Holocaust survivors in all generations, η2 P=.087 but only participants in the first generation reported higher PTG scores relative to the comparison group, with small effect sizes for the overall group differences, η2 P=.029 . These results are discussed in the historical and political context of postwar Czechoslovakia.

RESUMEN

Here we present a complex hypothesis about the psychosomatic mechanism of serotonergic psychedelics. Serotonergic psychedelics affect gut microbes that produce a temporary increase of 5-HT by their host enterochromaffin cells (ECs). This increased 5-HT production-which is taken up and distributed by platelets-may work as a hormone-like regulatory signal that could influence membrane permeability in the host organs and tissues and in the brain. Increased plasma 5-HT levels could enhance permeability of the blood-brain barrier (BBB). Transiently increased permeability of the BBB allows for plasma 5-HT to enter the central nervous system (CNS) and be distributed by the volume transmission. Next, this gut-derived 5-HT could modulate excitatory and inhibitory neurotransmission and produce special network disintegration in the CNS. This transient perturbation of the normal neural hierarchy allows patients access to suppressed fear information and perform an emotional reset, in which the amygdale may have a key role.

RESUMEN

BACKGROUND The early days of a given experience are associated with typically what might be characterized as an idealized enthusiasm. Conversely burnout syndrome experienced later in the given experience is associated with disillusionment, disappointment, and symptoms which resemble a depression. This very common propensity is a parallel to the concept of "splitting" described by Kernberg with a pronounced "black and white" perceptual dichotomy between the early idealization and later disillusionment. This study intends examination of relationships between burnout syndrome, depression, and Kernberg's concept of splitting. MATERIAL AND METHODS In this present study, we assessed 132 female health care professionals working with a population of diabetic patients utilizing Burnout Measure (BM) Splitting Index (SI), Beck Depression Inventory II (BDI-II), and additional psychometric instruments, the Toronto Alexithymia Scale and the Trauma Symptoms Checklist. RESULTS The study results indicated significant Spearman correlations between burnout syndrome as measured by BM and depression (BDI-II) (R=0.62, P<0.01), and burnout syndrome as measured by BM and splitting (SI) (R=0.45, P<0.01). These findings may have implications for prevention and treatment of burnout syndrome. CONCLUSIONS The current study findings provide implications that the defensive mechanism of splitting may allow for the prediction of burnout symptoms which in turn may allow for the prediction of burnout syndrome. This dynamics may potentially be of use in both the potential detection and prevention of burnout syndrome.

RESUMEN

BACKGROUND Obesity and associated comorbidities increase the probability of sexual disorders. The present study evaluated sexual satisfaction levels in obese women prior to and following bariatric surgery, utilizing the validated Female Sexual Function Index (FSFI) to also evaluate the sexual satisfaction in obese and non-obese women. MATERIAL AND METHODS 60 obese women (mean initial BMI of 43.7±5.9 kg/m²; mean age of 41.7±10.8 years) were administered the questionnaire on sexual function (FSFI) preceding bariatric surgery (laparoscopic adjustable gastric banding, 22 women; gastric plication, 33 women; and biliopancreatic diversion, 5 women), 6 months and 12 months after the procedure, i.e., following substantial weight reduction (final mean BMI of 35.5±5.5 kg/m²). The control group comprised 60 non-obese women (mean BMI of 22.2±1.9kg/m²; mean age of 36.4±10.7 years). RESULTS Our findings indicate that baseline sexual function in the preoperative obese females was significantly lower than in non-obese women, with p<0.01 in each domain. Data gathered at the 6- and 12-month points following the procedure indicated no significant difference. Before the procedure, 31 obese subjects (51.6%) exceeded the cutoff for FSD, at the 6-month evaluation point, 17 women (39.5%) exceeded the cutoff, and at 12 months postoperatively, 18 subjects (41.9%) exceeded the cutoff, indicative of FSD. Among the non-obese controls, only 9 subjects (15%) exceeded the cutoff threshold. CONCLUSIONS These findings show that substantive weight reduction resulting from bariatric surgery results in reduced sexual dysfunction in female subjects.

RESUMEN

OBJECTIVES: The default mode resting state network (DMRSN) constitutes a circuit which is active in conditions when the subject is at rest. We tested the hypothesis that its function will be altered during unconsciousness. METHODS: Changes in the mean squared coherences in five conventional frequency bands (delta to gamma) in DMRSN during general anaesthesia (GA) were investigated in 39 patients. They were compared with the normal EEG of 86 alert subjects, severely abnormal EEG of 112 patients with dementia and/or encephalopathy, and the mathematical model of brain death. RESULTS: Anaesthetised patients showed significant decrease in the gamma coherence in the posterior area of the DMRSN compared to both the control group and the patients with dementia and/or encephalopathy. Among the anaesthetized patients 21 had a clear burst suppression pattern with prolonged epochs of suppression in EEG. In suppressed EEG segment the differences between the connections of the anterior to posterior parts and connections between the posterior parts of the DMRSN were almost lost. However, they still showed highly significant differences in most items when compared with coherences in the mathematical model of brain death. CONCLUSION: The functional connectivity in the DMRSN could be a reliable and robust method for assessing the depth of anaesthesia and maybe also disorders of consciousness in general. The mean squared coherences in the gamma frequency band indicated the highest sensitivity for the depth of unconsciousness. The measure is not dependent on the diffused slowing in dementia or encephalopathy patients as long as they remain in a full consciousness.

RESUMEN

According to recent findings stressful experiences may influence various physiological disturbances and also neuroanatomical changes and some studies also show that psychotherapy and meditation may influence brain functions. Traumatic stress is frequently related to a dissociative response that disintegrates conscious experience. In this context, self-reflection is an essential principle in the process of posttraumatic growth related to spiritual experiences and meditation states that enable mental integration and create the novel integrated self. According to recent findings there is no widely accepted evidence about specific neural mechanisms of processes related to mental integration linked to the spiritual experiences and meditation. Nevertheless there is growing evidence that these integrative experiences are related to various alterations in the brain's physiology and morphology. These findings provide a new paradigm for understanding of mental disorders and emphasize the fundamental role of mental integration and integrated self in the therapy of psychiatric disorders.

RESUMEN

According to recent research, disturbances of self-awareness and conscious experience have a critical role in the pathophysiology of schizophrenia, and in this context, schizophrenia is currently understood as a disorder characterized by distortions of acts of awareness, self-consciousness, and self-monitoring. Together, these studies suggest that the processes of disrupted awareness and conscious disintegration in schizophrenia might be related and represented by similar disruptions on the brain level, which, in principle, could be explained by various levels of disturbed connectivity and information disintegration that may negatively affect usual patterns of synchronous activity constituting adaptive integrative functions of consciousness. On the other hand, mental integration based on self-awareness and insight may significantly increase information integration and directly influence neural mechanisms underlying basic pathophysiological processes in schizophrenia.

RESUMEN

Synesthesia is a condition in which stimulation of one sensory modality causes unusual experiences in a different, unstimulated modality. Recent findings suggest that research on synesthesia offers a unique opportunity to study the neural basis of subjective experiences in healthy and pathological brains. This review summarizes and reflects current knowledge concerning synesthesia in its various aspects, including its cognitive, neural, and behavioral aspects. In this context, recent data suggest new connections between specific conditions related to synesthesic mechanisms and association processes linked to construction of synesthetic cross-modal metaphors that may play a role in psychopathological thinking and imagination.

RESUMEN

Background: Burnout syndrome usually begins with feelings of enthusiasm and idealized visualizations, and it is in contrast with subsequent disillusionment, disappointment, and symptoms which are related to chronic stress experienced later. This tendency to idealization is a parallel to the concept of "mental splitting" described by Kernberg with a pronounced "black and white" perceptual dichotomy between the early idealization and later disillusionment. This study intends examination of relationships between burnout syndrome, traumatic stress and Kernberg's concept of splitting. Methods and participants: In this study we have assessed 90 health care professionals (50 women and 40 men) working with a population of diabetic patients utilizing Burnout Measure (BM), Splitting index (SI) and Traumatic Stress Checklist - 40 (TSC-40). Results: Study results indicate significant Spearman correlations between burnout syndrome (BM) and traumatic stress (TSC-40) in population of men (R=0.75, p<0.01) and of women (R=0.61, p<0.01), as well as between burnout syndrome (BM) and splitting (SI) for both genders: men (R=0.40, p<0.01), women (R=0.51, p<0.01). These findings may have implications for prevention and treatment of burnout syndrome. Conclusion: The current study findings provide implications that the defensive mechanisms of splitting and traumatic stress may allow for the prediction of burnout symptoms. This relation may potentially be of use in both the potential detection and prevention of burnout syndrome.

RESUMEN

Psychiatric and mood disorders may play an important role in the development and persistence of irritable bowel syndrome (IBS). Previously, we hypothesized that stress-induced implicit memories may persist throughout life via epigenetic processes in the enteric nervous system (ENS), independent of the central nervous system (CNS). These epigenetic memories in the ENS may contribute to developing and perpetuating IBS. Here, we further elaborate on our earlier hypothesis. That is, during pregnancy, maternal prenatal stresses perturb the HPA axis and increase circulating cortisol levels, which can affect the maternal gut microbiota. Maternal cortisol can cross the placental barrier and increase cortisol-circulating levels in the fetus. This leads to dysregulation of the HPA axis, affecting the gut microbiota, microbial metabolites, and intestinal permeability in the fetus. Microbial metabolites, such as short-chain fatty acids (which also regulate the development of fetal ENS), can modulate a range of diseases by inducing epigenetic changes. These mentioned processes suggest that stress-related, implicit, long-term epigenetic memories may be programmed into the fetal ENS during pregnancy. Subsequently, this implicit epigenetic stress information from the fetal ENS could be conveyed to the CNS through the bidirectional microbiota-gut-brain axis (MGBA), leading to perturbed functional connectivity among various brain networks and the dysregulation of affective and pain processes.

RESUMEN

Background: Intense fear of flying, called aviophobia, is a highly prevalent psychological phenomenon, afflicting (in some estimates) up to 40% of the population of industrialized countries and although aviophobia is a highly prevalent mental health problem, published studies about its epidemiology and treatment are rare. Methods: In this study, including 61 participants (28 males and 33 females; mean age 26.85) engaged in business related travels in the last two years, we assessed relationships of fear of flying problems with symptoms of stress also reflecting childhood traumatic stress experiences and its influences on brain sensitization and epileptic-like symptoms. In this assessment we also studied fear of flying symptoms and work related psychological problems described as burnout. Results: The results show that the participants who manifest higher levels of stress symptoms have higher levels of aviophobic experiences. Stress symptoms measured by TSC-40 manifested significant correlations with aviophobic experiences measured by Flight Anxiety Modality Questionnaire (FAS) (Spearman R=0.46, p<0.01). Other correlations were found between FAS and Limbic System Checklist (LSCL-33) (Spearman R=0.39, p<0.01) and FAS and Burnout Measure (BM) (Spearman R=0.30, p<0.01). Conclusion: The results of this study indicate that the experience of fear of flying is related to past and recent stressful events and also to levels of work related problems described and experienced as burnout.

RESUMEN

BACKGROUND: Somatoform dissociation is a specific form of dissociation with somatic manifestations represented in the form of 'pseudoneurological' symptoms due to disturbances or alterations of normal integrated functions of consciousness, memory or identity mainly related to trauma and other psychological stressors. With respect to the distinction between psychological and somatoform manifestations of dissociation current data suggest a hypothesis to which extent mild manifestations of 'pseudoneurological' symptoms in healthy young population may be linked to stress-related psychopathological symptoms or whether these symptoms more likely could be attributed to unexplained somatic factors. METHODS: With this aim we have assessed the relationship between somatoform dissociation and stress-related psychopathology (i.e. anxiety, depression, symptoms of traumatic stress, alexithymia) in a group of 250 healthy non-psychiatric and non-clinical young adults. RESULTS: Results of this study show that the symptoms of somatoform dissociation are significantly linked to stress-related psychopathology. CONCLUSIONS: Findings of this study show that the 'pseudoneurological' symptoms may be linked to stress-related psychopathological processes which indicate that also mild levels of stress may influence somatic feelings and may lead to various somatoform dissociative symptoms.

RESUMEN

One of the particularly important postnatal developmental reflexes that diminish in later stages of development is asymmetric tonic neck reflex (ATNR), which belongs among the so-called primitive reflexes. According to current evidence, certain later developed functions during ontogenesis of the central nervous system tend to replace the primitive reflexes, and their persistence is related to certain specific neuropsychiatric or neurological disorders. According to current knowledge, there is no evidence to which extent persistence of these reflexes may play a role in attention deficit and hyperactivity disorder (ADHD). With respect to these findings, we have tested a hypothesis to which extent persisting primitive reflex ATNR in 60 children in the school age (8-11 years) will be related to symptoms of ADHD and compared the results with 30 children of the same age. Results of this study show that ADHD symptoms are closely linked to persisting ATNR, which indicates that ADHD symptoms may present a compensation of unfinished developmental stages related to diminishing ATNR.

RESUMEN

There is evidence that neuropathic pain component in low back pain (LBP) patients is associated with higher ratings of comorbidities such as depression and anxiety disorders. In line with current findings, the purpose of this clinical study is to examine a hypothesis regarding a relationship of neuropathic pain component, depression, and other psychopathological symptoms in a specific group of LBP patients with sciatica pain. With respect to findings that depression is related to inflammatory changes, and inflammatory mediators may play a role in neuropathic pain generation, we have assessed also serum C-reactive protein (CRP). Results of the present study show that increased neuropathic pain component in sciatica patients is associated with elevated levels of depression, anxiety, alexithymia, and serum CRP levels. In conclusion, results of this study indicate that CRP levels in sciatica patients are closely associated with neuropathic pain.

RESUMEN

Development of sexual identity during adolescence is a major process of transition in individual life which in cases of ADHD specifically interacts with other ontogenetic, pathological and psychosocial conditions. According to recent findings growing consumption of internet pornography mainly in male ADHD population is closely related to compulsive sexual behavior and hypersexuality. Recent findings also indicate that consumption of internet pornography in ADHD individuals and other sexual activities may serve as a mood-altering "self-medication" which may help to cope with stressful events and decrease depression and anxiety. Taken together recent findings indicate that internet pornography consumption mainly in ADHD individuals is closely related to stressful experiences, anxiety, depression and identity problems in partnerships which significantly increase their vulnerability to the so-called "problematic pornography use" and other forms of addictive sexual behavior. From this developmental perspective "problematic pornography use" in ADHD individuals represents significant epidemiological problem which requires further research mainly with focus on clinical diagnostics and treatment.

RESUMEN

According to recent clinical data, epileptiform changes in temporolimbic structures may be related to psychopathological symptoms known to be related to stress. These data are also consistent with findings that temporal lobe epileptiform activity may provoke various somatic, sensory, behavioral, and memory disturbances similar to temporolimbic seizures and may lead to complex partial seizure-like symptoms which may also occur in nonepileptic conditions. Together, these findings suggest a hypothesis concerning the extent to which psychopathological changes usually related to stress may be associated with complex partial seizure-like symptoms or whether these symptoms might more likely be explained by various somatic factors. To test the hypothesis in a sample particularly vulnerable to stress, these relations between stress-related psychopathology and complex partial seizure-like symptoms were examined in a sample of 340 adolescents. Complex partial seizure-like symptoms were significantly associated with stress-related psychopathology: even mild stress may cause symptoms similar to cognitive and affective disturbances observed in patients with complex partial seizures.

RESUMEN

According to recent findings schizophrenia and bipolar disorder as separate disease entities manifest similarities in neuropsychological functioning. Typical disturbances in both disorders are related to sensory gating deficits characterized by decreased inhibitory functions in responses to various insignificant perceptual signals which are experimentally tested by event related potentials (ERP) and measured P50 wave. In this context, recent findings implicate that disrupted binding and disintegration of consciousness in schizophrenia and bipolar disorder that are related to inhibitory deficits reflected in P50 response may explain similarities in psychotic disturbances in both disorders. With this aim, this review summarizes literature about P50 in both schizophrenia and bipolar disorder.

RESUMEN

INTRODUCTION: Subjective cognitive deficits have been broadly reported in schizophrenia and described by Huber as basic symptoms. It remains unclear however to what extent they may be related to psychosocial stressors including trauma. METHODS: We assessed basic symptoms using the Frankfurt Complaint Questionnaire (FCQ) in a sample of 40 patients with schizophrenia. Trauma-related symptoms were assessed concurrently using the Trauma Symptom Checklist-40, symptoms of dissociation using the Dissociative Experiences Scale, and sensitization phenomena using the Complex Partial Seizure-like Symptoms Inventory and Limbic System Checklist-33. Psychotic symptoms were measured by Health of the Nation Outcome Scales. The dosage of antipsychotic medication was assessed in terms of equivalents of chlorpromazine, and antidepressant medication in terms of equivalents of fluoxetine. Spearman correlations were performed to explore the relationship between FCQ and other trauma-related measures. To determine the relative contributions of trauma-related symptoms to basic symptoms a linear regression analysis was performed. RESULTS: The results showed that higher levels of basic symptoms of schizophrenia were associated with greater levels of symptoms of dissociation, traumatic stress, and sensitization or kindling-like processes in schizophrenia. Among the trauma-related variables, sensitization phenomena assessed with Complex Partial Seizure-like Symptoms Inventory were closely associated with basic symptoms. DISCUSSION: These results indicate that basic symptoms measured by FCQ might be related to trauma. The potential of trauma to influence neurodevelopmental hypotheses of schizophrenia is discussed.
