RESUMEN

Nerve Growth Factor (NGF) and Brain derived Neurotrophic Factor (BDNF) mature/precursor imbalance in tears and serum is suggested as a risk factor and symptomatology aggravation in ophthalmology and neuropsychiatric disturbances. Cognitive and mood alterations are reported by patients with Graves' Orbitopathy (GO), indicating neurotrophin alterations might be involved. To address this question, the expression levels of NGF and BDNF and their precursors in serum and tears of GO patients were analyzed and correlated with the ophthalmological and psycho-cognitive symptoms. Hamilton Rating Scale for Anxiety (HAM-A) and Depression (HAM-D), Temperament and Character Inventory (TCI), and Cambridge Neuropsychological Test Automated Battery (CANTAB) test were used as a score. NGF and BDNF levels were measured using ELISA and Western Blot and statistically analyzed for psychiatric/ocular variable trend association. GO patients show memorization time and level of distraction increase, together with high irritability and impulsiveness. HAM-A and CANTAB variables association, and some TCI dimensions are also found. NGF and BDNF expression correlates with ophthalmological symptoms only in tears, while mature/precursor NGF and BDNF correlate with the specific psycho-cognitive variables both in tears and serum. Our study is the first to show that changes in NGF and BDNF processing in tears and serum might profile ocular and cognitive alterations in patients.

RESUMEN

OBJECTIVE: Endocannabinoids have been implicated in the pathophysiology of Major Depressive Disorder (MDD) and might represent potential targets for therapeutic intervention. Objectives of the study were: (1) to measure plasma levels of endocannabinoids in a group of antidepressant-free depressed outpatients; (2) to explore their relationship with the severity of depressive symptoms as subjectively perceived by the patients; and (3) to investigate the effect of the selective serotonin reuptake inhibitor escitalopram on endocannabinoid levels. METHODS: We measured plasma levels of the two major endocannabinoids, 2-arachidonoylglycerol (2-AG) and N-arachidonoylethanolamine (anadamide), in 12 drug-free outpatients diagnosed with MDD and in 12 matched healthy controls. In the patient group, endocannabinoids plasma levels were assessed at baseline and after 2 months of treatment with escitalopram. RESULTS: Baseline plasma levels of the two endocannabinoids did not differ between depressed patients and healthy controls. However, there was a significant inverse correlation between 2-arachidonoylglycerol levels and the severity of subjectively perceived depressive symptoms. Treatment with escitalopram did not change endocannabinoid levels in depressed patients, although it caused the expected improvement of depressive symptoms. CONCLUSIONS: Our results suggest that 2-arachidonylglycerol, the most abundant endocannabinoid in the central nervous system, might act to mitigate depressive symptoms, and raise the interesting possibility that 2-arachidonylglycerol and anandamide are differentially regulated in patients affected by MDD. Also, our data suggest but do not prove that the endocannabinoid system is not regulated by serotonergic transmission, at least in depressed patients.

RESUMEN

Even more than for other treatments, great importance must be given to informed consent in the case of electroconvulsive therapy (ECT). In a percentage of cases, the symbolic connotation of the treatment, even if mostly and intrinsically negative, may actually be a determining factor in the patient's motives for giving consent. On an ethical and medicolegal level, the most critical point is that concerning consent to the treatment by a psychotic subject with a severely compromised ability to comprehend the nature and objective of the proposed therapy, but who nonetheless expresses his consent, for reasons derived from delusional thoughts. In fact, this situation necessarily brings to light the contradiction between an explicit expression of consent, a necessary formality for the commencement of therapy, and the validity of this consent, which may be severely compromised due to the patient's inability to comprehend reality and therefore to accept the proposal of treatment, which is intrinsic to this reality. With the use of an electric current, the symbolic experience associated with anaesthesia, and the connection to convulsions, ECT enters the collective consciousness. In relation to this, ECT is symbolic of these three factors and hooks on to the thoughts, fears, feelings and expectations of delusional patients. These are often exemplified in the violent intervention of the persecutor in the patient with schizophrenia, the expected punishment for the 'error' committed for which the depressed patient blames himself and the social repression of the maniacal patient's affirmation of his inflated self-esteem.

RESUMEN

OBJECTIVE: Accumulating evidence is delineating a neuroprotective/neurotrophic role for lithium. However, its primary effects on cognition remain ambiguous. We sought to investigate the profile of cognitive impairment in patients with bipolar disorder and to determine whether continued treatment with lithium preserves cognitive functioning. METHODS: In this cross-sectional study, we tested 15 euthymic patients with bipolar I disorder undergoing long-term clinical maintenance treatment with lithium (for at least 12 months), 15 matched patients treated with other mood-stabilizing drugs and who had never received lithium, and 15 matched healthy subjects on the Cambridge Neuropsychological Test Automated Battery. Investigated cognitive domains were visual memory, executive functions, attention, decision-making/impulsivity, and response inhibition. We controlled for age, gender, intelligence, and residual psychiatric symptomatology. RESULTS: Taken together, bipolar patients demonstrated robust deficits in visual memory and executive functions. Once subdivided in treatment subgroups, only non-lithium bipolar patients demonstrated impairments in visual memory. Attention, decision-making, and response inhibition were preserved in both groups. No correlation emerged between neuropsychological tests performance, clinical, and psychological variables. CONCLUSIONS: This study is the first to our knowledge to have demonstrated, by means of a highly sensitive test of visual memory, a potential hippocampus neuroprotective effect of lithium in patients with bipolar disorder. Besides, it confirms prior findings of cognitive deficits in euthymic bipolar patients.

RESUMEN

War is a complex issue and, as such, observable and studyable from different perspectives, including political, economic, anthropological, sociological, ethnological, etological, historical and psychological. Psychiatry's interest in war has a historical root, just think of the Psychoanalytic Congress held in Budapest in September 1918, on "war neuroses". Current interest is directed to psychic mechanisms operating in the war phenomenon and on the consequences that collective trauma produces in acute, chronic and in subsequent generations.

RESUMEN

INTRODUCTION: Prenatal alcohol exposure causes a variety of impairments to the fetus called Fetal Alcohol Spectrum Disorders (FASD). Since it is very difficult to identify women that consume alcohol during pregnancy, different methods have been studied to evaluate alcohol exposure. Ethyl Glucuronide (EtG) and Fatty Acid Ethyl Esters (FAEEs) are commonly used to measure alcohol consumption in individuals at-risk for alcohol abuse, including pregnant women. MATERIALS AND METHODS: We conducted a study of two cohorts of 1.5 year-old infants (of mothers without a history of alcohol abuse) with or without meconium samples positive to both EtG and FAEEs and we evaluated their cognitive-behavioral development by the Griffiths Mental Developmental Scale (GMDS) method. Our protocol included 8 infants with meconium positive to alcohol metabolites (EtG and FAEEs) and 7 with meconium negative to alcohol metabolites. RESULTS: None of the 8 alcohol metabolites positive meconium infants exhibited distinctive facial features and growth retardation of severe FASD, showing that other factors may contribute to the FASD onset but elevations in EtG and FAEEs in the meconium were significantly associated with disrupted neurodevelopment and adaptive functions within the first year and a half of life. Indeed, we found out that infants with meconium positive for both EtG and FAEEs, although without displaying any FASD morphological features, had a delay in the fine regulation of their own locomotory capabilities. CONCLUSIONS: Further analyses and larger studies are needed to estimate the right link between prenatal alcohol exposure and the different range of disorders connected but this study provides an additional step in the field of FASD in order to suggest early treatments for at-risk newborns and infants.

RESUMEN

A recent euthanasia case in Belgium has garnered attention due to its particularly dramatic aspects, sparking clinical and ethical questions about end-of-life choices in cases of mental suffering. A 56-year-old woman, convicted of the murder of her five minor children and sentenced to life imprisonment, has been granted euthanasia for "irreversible psychological suffering". The clinical and psychodynamic aspects of the case, primarily deduced from press reports, are highly complex and give rise to numerous clinical, medico-legal, and bioethical questions. These include inquiries into the true nature of psychopathology, its actual irreversibility, its impact on the ability to express a euthanasia request with adequate awareness, the preserved capacity for self-determination, and broader issues related to end-of-life requests from patients with mental disorders. These aspects are considered in the context of the legislation in various European countries. The unique details of this case underscore the critical challenges associated with these complex issues.

RESUMEN

AIM: Neurological Soft Signs (NSS) represent minor neurological signs related to non-specific cerebral alterations. They have been documented in many psychiatric disorders including schizophrenia (SCZ) and obsessive-compulsive disorder (OCD). Aim of this study was to determine and compare the incidence and severity of NSS in patients with SCZ, in patients with OCD, and healthy control subjects (HCs). METHODS: Using the Neurological Evaluation Scale (NES), this study investigated NSS in 15 SCZ patients, 14 OCD patients, and 15 HCs. PANSS and Y-BOCS were used to evaluate clinical picture in both groups. RESULTS: Patients with SCZ showed significantly higher scores compared to HCs in the NES total and each of the three NES subscales (Integrative Sensory Function, Motor Coordination, and Sequencing of Complex Motor Acts). Patients with OCD also showed significantly higher scores compared to HCs in the NES total, Motor Coordination and Sequencing of Complex Motor Acts, but not in Integrative Sensory Function. No significant differences emerged in the NES total and the various subscales scores between the two patients' groups. CONCLUSIONS: Our results seem to confirm the presence of NSS in both SCZ and OCD. The different types of NSS presented by the two patients' groups versus HCs further supports the findings of widespread cerebral alterations in SCZ, on the other hand, with a preferential involvement of prefrontal and frontal cortex in OCD.

RESUMEN

Sleep problems and circadian rhythms disturbances are common in many psychiatric disorders, with the most often-reported sleep problem in most cases being insomnia. In this paper, the main findings about sleep disturbances(features and therapy) and other biorhythm disturbances (biological timekeepers, CLOCK genes, GSK3, melatonin, hypothalamo-pituitary-adrenal axis, body temperature) are reviewed in relation to schizophrenia, mood and anxiety disorders.

RESUMEN

INTRODUCTION: BDNF is present in human serum and its level changes have been used as a marker of antidepressant efficacy in some psychiatric disorders. In addition, the positive effects of light therapy on major depression suggest that circadian-regulated factors should be taken into account in the management of mood disorders. The aim of the present study was to test ultradian fluctuations in serum and salivary BDNF levels and their interaction with light therapy in a sample of healthy women. METHODS: The study included 16 young women. Psychopathological status and chronotype traits were assessed by SPAQ, BDI, STAI, TAS, and MEQ. Standard light treatment protocol was applied. Serum and saliva were collected at 8.00, 13.00 and 20.00 hrs on the same day and at the end of light therapy. RESULTS: BDNF levels declined over the course of the day both in serum and saliva, and a correlation between diurnal BDNF trend and personality traits and habits characterizing the morning and evening types in healthy women was found. CONCLUSIONS: The present study is one of the first to show measurable BDNF in human saliva and to demonstrate its daily fluctuations in both saliva and serum of healthy young women. The correlation between diurnal changes in BDNF and the personality traits associated with body rhythms corroborates the notion that salivary BDNF may be a useful biomarker for stress-related research and different clinical investigations.

RESUMEN

INTRODUCTION: In recent months, a great uproar has been aroused by the case of a 23-year-old Belgian woman who requested and obtained euthanasia because she was suffering from a mental disorder, in the absence of any somatic pathology. The news raises some questions and stimulates some reflections both on the general theme of euthanasia carried out for the simple presence of a mental disorder, and for the indefiniteness of the clinical information on the case in question, as well as on the ethical and medico-legal questions connected to such indefiniteness. CASE PRESENTATION: The information on the case was derived essentially from the press and from websites, with no specific access to actual clinical documentation and without in-depth knowledge of case details. One wonders what the real clinical diagnosis of the patient was, only hypothetically identifiable in a Post-traumatic Stress Disorder associated with Major or Chronic Depressive Disorder, probably on the basis of a possible Personality Disorder. One wonders if all the necessary therapeutic interventions had been implemented, in a clinical case that did not theoretically have the characteristics of incurability. One wonders why the death request was considered valid, in a subject perhaps suffering from a mental disorder of such severity as to alter the ability to express valid consent to medical treatment. One wonders why the death request was not considered as an indicator of the severity of the disease, rather than simply being considered as a free choice of a subject capable of self-determination. One wonders why the negative opinion of the patient's family members was not considered. CONCLUSIONS: Belgian legislation provides for euthanasia for patients suffering from mental disorders who, like those suffering from somatic disorders, experience a condition of constant, unbearable and incurable suffering. But the case in question raises numerous perplexities both on the clinical and ethical coherence of Belgian legislation and on the ways in which the rules of this legislation have been observed in this specific situation.

RESUMEN

INTRODUCTION: The homicide of the female partner followed by suicide of the perpetrator (Intimate Female Partner Homicide Suicide - IFPHS) has been a growing phenomenon over last years, but its psychosocial and psychopathological aspects have not been analyzed in-depth yet. PURPOSE: The aim of this study was to investigate common psychopathological elements in different IFPHS and a specific risk profile for both the couple and the male partner, with the possibility to define a new serial mental condition not classified to date. METHODS: A series of 50 cases of greater media coverage was reconstructed from the Italian newspapers in the period from 2009 to 2019 and information was collected through a predefined form. The characteristics of the perpetrators and the modalities through which the events occurred have been considered. RESULTS: No definite mental disorder is present in the history of almost all cases. A more common psychological profile is found for the homicide/suicide male partner, mainly characterized by jealousy, possessiveness, mood reactivity, rage, and impulsiveness. CONCLUSIONS: It can be hypothesized that such a severe act may express a form of mental disorder not yet classified, with main features of an acute state of mixed depressive mood, emotional discontrol and aggressive impulsiveness, on a personality basis of jealousy and possessiveness, possibly reinforced by previous dependent traits of the female partner. But the methodological limitations of gathering information from the press make it necessary the study in depth, based on more direct and objective methodologies, of such a highly dramatic and heterogeneous phenomenon.

RESUMEN

OBJECTIVES: : The objective of this study was to investigate the immediate response of the dopamine-regulated growth hormone (GH) to electroconvulsive therapy (ECT) in schizophrenic patients and the changes in the serum GH levels throughout the consecutive sessions of the therapeutic ECT course. METHODS: : Serum GH levels were measured in a sample of 11 men with schizophrenia according to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, who were administered a course of 8 bilateral ECT treatments. Measurements were performed 5 minutes before ECT, during ECT, 15 minutes after an ECT session, and 30 minutes after an ECT session during the first, fourth, and eighth ECT sessions. RESULTS: : At both the fourth and the eighth ECT sessions, a significant decrease in GH levels 15 and 30 minutes after ECT was observed compared with the baseline values. No change in baseline serum GH levels was observed either during or at the end of the treatment. Clinical improvement was indicated by a significant reduction in the total score, negative subscale score, and positive subscale score of the Positive and Negative Syndrome Scale. CONCLUSIONS: : The results are consistent with the potential role of immediate serum GH changes as an index of potential dopamine-mediated response to ECT. It can be assumed that GH reduction may be partially related to an antidopaminergic action of ECT, but further research is still needed to better evaluate the correlation of the dopamine system instability during the course of the illness with the previously mentioned immediate treatment response. Also, the role of other neurotransmitters in the regulation of GH production and ECT response must be taken into account for the purpose of an overall evaluation of the results and of their potential clinical implications.

RESUMEN

OBJECTIVE: Chocolate consumption has long been associated with enjoyment and pleasure. Popular claims confer on chocolate the properties of being a stimulant, relaxant, euphoriant, aphrodisiac, tonic and antidepressant. The aim of our study was to validate and to verify the reliability of the Italian version of the Attitudes to Chocolate Questionnaire (ACQ) which evaluates different dimensions of chocolate craving experience. METHODS: The Italian version of ACQ was administered to a sample consisting of 1609 adults, recruited among students of the University of L'Aquila and general population. The subjects also completed the Stress-Related Vulnerability Scale (SVS), which assesses the level of stress and social support received. RESULTS: This study showed a good degree of stability and internal consistency of the two-factor model, respectively represented by craving and sense of guilt, in comparison to previous ones. The scoring for both factors resulted greater in women than in men. Subjects of younger age and with lower Body Mass Index (BMI) achieved higher scores in relation to the craving dimension, while a positive correlation was observed between age and sense of guilt. Finally the total scoring at SVS and its subscales resulted significantly interrelated with the two factors. CONCLUSIONS: Our study confirms the validity and the reliability of the Italian version of the two-factors based ACQ scale and strongly underlines the association between perceived stress and dysfunctional approach to chocolate consumption.

RESUMEN

PURPOSE: The aim of this study was to provide an Italian validation of the Premenstrual Symptoms Screening Tool (PSST). The PSST is a retrospective questionnaire, originally developed in English language, used for the screening of Premenstrual Syndrome (PMS) and of Premenstrual Dysphoric Disorder (PMDD). PMDD and PMS are common, but are often not adequately recognized and treated, although they can heavily interfere on women's quality of life. METHODS: An Italian version of the PSST from English was prepared using the "forward-backward" procedure, and submitted to a sample of 520 women over 18 years of age (mean age of 23.6; DS=±3.1). The content validity, the internal consistency, the test-retest reliability, and the convergent validity were evaluated. The factorial structure underlying the questionnaire was assessed with the use of both Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA). RESULTS: Among the 520 participants to the study, 337 experienced no or mild premenstrual symptoms (64.8%), while 158 women evidenced a positive screening for moderate or severe PMS (30.4%), and 23 for PMDD (4.4%). The Italian PSST displayed adequate content validity and a very good internal consistency, with a Cronbach's alpha of 0.89. The test-retest reliability showed satisfactory results, with a Spearman's ρ for the overall score of 0.80, and the intra-class correlation coefficient (ICC) of 0.810 (95% CI=0.761-0.862; p<0.001). The EFA was performed using the principal component analysis, followed by varimax rotation. The CFA was conducted on EFA results and supported a four-factor model, yielding the best fit indices [χ2/df=1.76; CFI=0.920; TLI=0.904; RMSEA=0.054 (0.043-0.065)]. The convergent validity, evaluated using the Spearman's correlation coefficient between the overall score of the Italian version of PSST and the Beck Depression Inventory (BDI) score showed a good value (ρ=0.647 p<0.001). CONCLUSION: Our results support the cross-cultural validity of the questionnaire, suggesting that the Italian version is a reliable and valid tool, as well as easy to use, to screen women in need of treatment for their premenstrual symptoms.

RESUMEN

The nerve growth factor (NGF) belongs to the family of neurotrophic factors. Initially discovered as a signaling molecule involved in the survival, protection, differentiation, and proliferation of sympathetic and peripheral sensory neurons, it also participates in the regulation of the immune system and endocrine system. NGF biological activity is due to the binding of two classes of receptors: the tropomyosin-related kinase A (TrkA) and the low-affinity NGF pan-neurotrophin receptor p75. Alcohol Use Disorders (AUD) are one of the most frequent mental disorders in developed countries, characterized by heavy drinking, despite the negative effects of alcohol on brain development and cognitive functions that cause individual's work, medical, legal, educational, and social life problems. In addition, alcohol consumption during pregnancy disrupts the development of the fetal brain causing a wide range of neurobehavioral outcomes collectively known as fetal alcohol spectrum disorders (FASD). The rationale of this review is to describe crucial findings on the role of NGF in humans and animals, when exposed to prenatal, chronic alcohol consumption, and on binge drinking.

RESUMEN

We aimed at investigating the gender and/or ultradian pattern of serum levels of the Nerve Growth Factor (NGF) and Brain-Derived Neurotrophic Factor (BDNF). Blood samples were collected at the 8.00, 13.00 and 20.00 hours of the day in healthy men and women, and the neurotrophins concentration was measured in the serum by ELISA. A further aim of the study was to evaluate whether or not the NGF/BDNF variations might be related to specific physiological or psychological traits as mood, feeling good and feeling rested, sexual desire and energy. Heart rate and blood pressure were also monitored at the same hours in each enrolled subject. The anxiety (STAI-T and STAI-S score) and sleeping quality were once evaluated in the morning too. We found that serum BDNF increases in men and decreases in women from morning to evening, while NGF shows a similar ultradian profile between men and women, but with higher concentrations in women. Both neurotrophins also show gender-related associations with psychophysiological variables. High NGF levels correlated with a high score for all the psychological variables in men, but with a low score in women. An inverse correlation was found between BDNF and energy and sexual desire in women, while no correlations were found in men. These data disclose that the condition of well-being (or activity/arousal status) is featured by an increasing NGF profile in men and a negative BDNF/NGF trend in women. The clinical relevance of the present data is discussed.

RESUMEN

Stress is a constant threat for homeostasis and is represented by different extrinsic and intrinsic stimuli (stressors, Hans Selye's "noxious agents"), such as aggressive behavior, fear, diseases, physical activity, drugs, surgical injury, and environmental and physiological changes. Our organisms respond to stress by activating the adaptive stress system to activate compensatory responses for restoring homeostasis. Nerve Growth Factor (NGF) was discovered as a signaling molecule involved in survival, protection, differentiation, and proliferation of sympathetic and peripheral sensory neurons. NGF mediates stress with an important role in translating environmental stimuli into physiological and pathological feedbacks since NGF levels undergo important variations after exposure to stressful events. Psychological stress, lifestyle stress, and oxidative stress are well known to increase the risk of mental disorders such as schizophrenia, major depressive disorders, bipolar disorder, alcohol use disorders and metabolic disorders such as metabolic syndrome. This review reports recent works describing the activity of NGF in mental and metabolic disorders related to stress.

RESUMEN

The goal of this investigation was to evaluate corpus callosum (CC) morphometry in schizophrenia. In consideration of possible confounders such as age, gender and handedness, our study sample was restricted to right-handed male subjects, aged 18-55 years. In addition, we controlled for age at onset, illness duration and exposure to antipsychotic medication. Midsagittal CC linear and area Magnetic Resonance Imaging (MRI) measurements were performed on 50 subjects with schizophrenia and 50 healthy controls. After controlling for midsagittal cortical brain area and age, Analysis of Covariance (ANCOVA) revealed an overall effect of diagnosis on CC splenium width and CC anterior midbody area and a diagnosis by age interaction. Independent Student t tests revealed a smaller CC splenium width in the 36- to 45-year-old age group among the patients with schizophrenia and a smaller CC anterior midbody area in the 18- to 25-year-old age group among the patients with schizophrenia compared with controls. Age, age at onset, illness duration and psychopathology ratings did not show any significant correlations with the whole CC MRI measurements. A negative correlation was found between CC rostrum area and the estimated lifetime neuroleptic consumption. The results are discussed in terms of the possibility that CC structural changes may underlie the functional impairments, frequently reported in schizophrenia, of the associated cortical regions.

RESUMEN

CoViD-19 pandemic is causing serious consequences on mental health, consequences that are considered that bad that World Health Organization has affirmed that mental health defence is priority in this particular moment of development of pandemic. In light of this alertness, what we are interested in approaching in this work, is the specific stress condition caused by pandemic, which underlies and precedes the described classification of diseases and which is going towards an increase in the entire world, including Italy. The stress caused by pandemic is a new condition in comparison with what is known in clinical practice and with what is included in the classification of mental disorder. The ongoing stress condition and the mixture of different types of unconventional stress, which not only hits the present but also disrupts the future, create an entirely new form of clinical condition given by pandemic.
