Association between Chronic Misophonia-Induced Stress and Gastrointestinal Pathology in Children-A Hypothesis.

Misophonia is a neurophysiological disorder with behavioral implications, is complex and multifactorial in origin, and is characterized by an atypical and disproportionate emotional response to specific sounds or associated visual stimuli. Triggers include human-generated sounds, mainly sounds related to feeding and breathing processes, and repetitive mechanical sounds. In response to the triggering stimulus, the patient experiences immediate, high-intensity, disproportionate physical and emotional reactions that affect their quality of life and social functioning. The symptoms of misophonia can occur at any age, but onset in childhood or adolescence is most common. Affected children live in a constant state of anxiety, suffer continuous physical and emotional discomfort, and are thus exposed to significant chronic stress. Chronic stress, especially during childhood, has consequences on the main biological systems through the dysregulation of the hypothalamic-pituitary-adrenal axis, including the gastrointestinal tract. Here, we provide arguments for a positive correlation between misophonic pathology and gastrointestinal symptoms, and this hypothesis may be the starting point for further longitudinal studies that could investigate the correlations between these childhood vulnerabilities caused by misophonia and their effect on the gastrointestinal system. Further research to study this hypothesis is essential to ensure correct and timely diagnosis and optimal psychological and pharmacological support.

The Contribution of Genetic Testing in Optimizing Therapy for Patients with Recurrent Depressive Disorder.

(1) Background: The aim of this study was to analyze the impact of pharmacogenetic-guided antidepressant therapy on the 12-month evolution of the intensity of depressive symptoms in patients with recurrent depressive disorder (RDD) in comparison to a control group of depressive subjects who were treated conventionally. (2) Methods: This prospective longitudinal study was conducted between 2019 and 2022, and the patients were evaluated by employing the Hamilton Depression Rating Scale (HAM-D), Hamilton Anxiety Rating Scale (HAM-A) and the Clinical Global Impressions Scale: Severity and Improvement. We followed them up at 1, 3, 6, and 12 months. (3) Results: Of the 76 patients with RDD, 37 were tested genetically (Group A) and 39 were not (Group B). Although the patients from Group A had statistically significantly more severe MDD at baseline than those from Group B (p < 0.001), by adjusting their therapy according to the genetic testing, they had a progressive and more substantial reduction in the severity of RDD symptoms [F = 74.334; η2 = 0.674; p < 0.001], indicating a substantial association with the results provided by the genetic testing (67.4%). (4) Conclusions: In patients with RDD and a poor response to antidepressant therapy, pharmacogenetic testing allows for treatment adjustment, resulting in a constant and superior reduction in the intensity of depression and anxiety symptoms.

The Influence of Personality Traits on Postpartum Depression: A Systematic Review Based on the NEO-FFI Scale.

Postpartum depression (PPD) is a significant global health concern with profound implications for mothers, families, and societies. This systematic review aims to synthesize current research findings to understand better how personality traits, as assessed by the NEO Five-Factor Inventory (NEO-FFI), contribute to the development and progression of PPD. Conducted in January 2024, this review searched major databases like PubMed, PsycINFO, and Scopus up to December 2023, focusing on the NEO-FFI's role in evaluating PPD. Following PRISMA guidelines, studies were selected based on strict criteria, including the exclusive use of NEO-FFI for personality assessment and a focus on postpartum women. A total of seven studies were included after a rigorous two-step screening process, and their data were qualitatively synthesized. The review covered a total of 4172 participants, with a prevalence of clinically significant postpartum depression symptoms ranging from 10.6% to 51.7%. Notably, Neuroticism emerged as a significant predictor of PPD, with odds ratios ranging from 1.07 (95% CI: 0.96-1.20) in some studies to as high as 1.87 (95% CI: 1.53-2.27) in others. In contrast, traits like Extraversion and Conscientiousness generally showed protective effects, with lower scores associated with reduced PPD risk. For instance, Extraversion scores correlated negatively with PPD risk (Beta = -0.171) in one study. However, the impact of other traits such as Openness and Agreeableness on PPD risk was less clear, with some studies indicating negligible effects. The review highlights Neuroticism as a consistent and significant predictor of PPD risk, with varying impacts from other personality traits. The findings suggest potential pathways for targeted interventions in maternal mental health care, emphasizing the need for comprehensive personality evaluations in prenatal and postnatal settings.

Epigenetic and Coping Mechanisms of Stress in Affective Disorders: A Scoping Review.

This review aims to explore the intricate relationship among epigenetic mechanisms, stress, and affective disorders, focusing on how early life experiences and coping mechanisms contribute to susceptibility to mood disorders. Epigenetic factors play a crucial role in regulating gene expression without altering the DNA (deoxyribonucleic acid) sequence, and recent research has revealed associations between epigenetic changes and maladaptive responses to stress or psychiatric disorders. A scoping review of 33 studies employing the PRISMA-S (Preferred Reporting Items for Systematic Reviews and Meta-Analyses-Statement) guidelines investigates the role of stress-induced epigenetic mechanisms and coping strategies in affective disorder occurrence, development, and progression. The analysis encompasses various stress factors, including childhood trauma, work-related stress, and dietary deficiencies, alongside epigenetic changes, such as DNA methylation and altered gene expression. Findings indicate that specific stress-related genes frequently exhibit epigenetic changes associated with affective disorders. Moreover, the review examines coping mechanisms in patients with bipolar disorder and major depressive disorder, revealing mixed associations between coping strategies and symptom severity. While active coping is correlated with better outcomes, emotion-focused coping may exacerbate depressive or manic episodes. Overall, this review underscores the complex interplay among genetic predisposition, environmental stressors, coping mechanisms, and affective disorders. Understanding these interactions is essential for developing targeted interventions and personalized treatment strategies for individuals with mood disorders. However, further research is needed to elucidate specific genomic loci involved in affective disorders and the clinical implications of coping strategies in therapeutic settings.

Evaluating the Connection between MicroRNAs and Long Non-Coding RNAs for the Establishment of the Major Depressive Disorder Diagnosis.

The most prevalent mental illness worldwide and the main contributor to suicide and disability is major depressive disorder. Major depressive disorder is now diagnosed and treated based on the patient's statement of symptoms, mental status tests, and clinical behavioral observations. The central element of this review is the increased need for an accurate diagnostic method. In this context, the present research aims to investigate the potential role of two non-coding RNA species (microRNA and long non-coding RNA) in peripheral blood samples and brain tissue biopsy from patients with major depressive disorder. This study reviewed the literature on microRNA and long non-coding RNA expression in blood and brain tissue samples in human and animal depression models by retrieving relevant papers using the PubMed database. The results reveal significant variations in microRNA and long non-coding RNA levels in depressed patients, making it a crucial diagnostic tool that predicts treatment outcomes. It can help track severe cases and adjust therapy dosages based on treatment responses. In conclusion, microRNAs and long non-coding RNAs are pertinent biomarkers that can be added to the diagnostic test panel for major depressive disorder. Both microRNAs and non-coding RNAs can also be used as a tool to track patient progress during therapy and to assist the attending physician in tracking the molecular development of the disease.

Involvement of the Expression of G Protein-Coupled Receptors in Schizophrenia.

The expression of GPCRs has been associated with schizophrenia, and their expression may induce morphological changes in brain regions responsible for schizophrenia and disease-specific behavioral changes. The articles included in this review were selected using keywords and databases of scientific research websites. The expressions of GPRs have different involvements in schizophrenia, some increase the risk while others provide protection, and they may also be potential targets for new treatments. Proper evaluation of these factors is essential to have a better therapeutic response with a lower rate of chronicity and thus improve the long-term prognosis.

The Impact of the COVID-19 Pandemic on Depressive Disorder with Postpartum Onset: A Cross-Sectional Study.

BACKGROUND: COVID-19 has led to a global health crisis that is defining for our times and one of the greatest challenges to emerge since World War II. The potential impact of the pandemic on mental health should not be overlooked, especially among vulnerable populations such as women who gave birth during the COVID-19 pandemic. MATERIALS AND METHODS: The study is a cross-sectional survey conducted from 1 March 2020 to 1 March 2023, during the period of the SARS-CoV-2 (COVID-19) pandemic, based on a retrospective evaluation of 860 postpartum women. The screening tool used to assess symptoms of postpartum depression was the Edinburgh Postnatal Depression Rating Scale (EPDS) questionnaire. The questionnaire was completed both in the Obstetrics and Gynaecology Clinical Sections I and II of the "Pius Brînzeu" County Emergency Hospital in Timisoara, Romania, and online using Google Forms. RESULTS: The highest severity of postpartum depression symptoms was observed during the COVID-19 pandemic. The results of the study conducted during the period of the SARS-CoV-2 pandemic (COVID-19) showed that the prevalence of major postpartum depressive disorder (EPDS ≥ 13) was 54.2% (466 patients), while 15.6% (134) had minor depressive disorder (10 < EPDS ≤ 12) in the first year after delivery. Comparing these results with those obtained in research conducted before the onset of the pandemic period showed an alarming increase in the prevalence of postpartum depression. The risk factors associated with postpartum depression included the type of delivery, level of education, socio-economic conditions, health status, age, background, and personal obstetric history (number of abortions on demand, parity). CONCLUSIONS: The effects of the pandemic on mental health are of particular concern for women in the first year after childbirth. Observing these challenges and developing effective measures to prepare our health system early can be of great help for similar situations in the future. This will help and facilitate effective mental health screening for postpartum women, promoting maternal and child health.

Uncovering the Roles of MicroRNAs in Major Depressive Disorder: From Candidate Diagnostic Biomarkers to Treatment Response Indicators.

Major depressive disorder (MDD) is a recurrent debilitating illness that represents a major health burden due to its increasing worldwide prevalence, unclear pathological mechanism, nonresponsive treatment, and lack of reliable and specific diagnostic biomarkers. Recently, microRNA species (miRs) have gained particular interest because they have the ability to post-transcriptionally regulate gene expression by modulating mRNA stability and translation in a cohesive fashion. By regulating entire genetic circuitries, miRs have been shown to have dysregulated expression levels in blood samples from MDD patients, when compared to healthy subjects. In addition, antidepressant treatment (AD) also appears to alter the expression pattern of several miRs. Therefore, we critically and systematically reviewed herein the studies assessing the potential biomarker role of several candidate miRs for MDD, as well as treatment response monitoring indicators, in order to enrich the current knowledge and facilitate possible diagnostic biomarker development for MDD, which could aid in reducing both patients' burden and open novel avenues toward a better understanding of MDD neurobiology.

Untargeted Plasma Metabolomic Profiling in Patients with Major Depressive Disorder Using Ultra-High Performance Liquid Chromatography Coupled with Mass Spectrometry.

Major depressive disorder (MDD) is a neuropsychiatric illness with an increasing incidence and a shortfall of efficient diagnostic tools. Interview-based diagnostic tools and clinical examination often lead to misdiagnosis and inefficient systematic treatment selection. Diagnostic and treatment monitoring biomarkers are warranted for MDD. Thus, the emerging field of metabolomics is a promising tool capable of portraying the metabolic repertoire of biomolecules from biological samples in a minimally invasive fashion. Herein, we report an untargeted metabolomic profiling performed in plasma samples of 11 MDD patients, at baseline (MDD1) and at 12 weeks following antidepressant therapy with escitalopram (MDD2), and in 11 healthy controls (C), using ultra-high performance liquid chromatography coupled with electrospray ionization-quadrupole-time of flight-mass spectrometry (UHPLC-QTOF-(ESI+)-MS). We found two putative metabolites ((phosphatidylserine PS (16:0/16:1) and phosphatidic acid PA (18:1/18:0)) as having statistically significant increased levels in plasma samples of MDD1 patients compared to healthy subjects. ROC analysis revealed an AUC value of 0.876 for PS (16:0/16:1), suggesting a potential diagnostic biomarker role. In addition, PS (18:3/20:4) was significantly decreased in MDD2 group compared to MDD1, with AUC value of 0.785.

Social Inferences as Mediators of Wellbeing in Depression.

BACKGROUND: Depression is an increasingly prevalent chronic mental health condition that involves a range of potentially negative implications, in the long term. Theory of Mind (ToM) serves to form and maintain social relationships, by accurately identifying thoughts and emotions in others. Defective ToM abilities have been noted in people with a history of clinical depression. PURPOSE: To identify whether impairments of emotion recognition are correlated with a lower subjective feeling of wellbeing in people diagnosed with a chronic depressive illness. PATIENTS AND METHODS: In a cross-sectional analysis of a recurrent depressive disorder (RDD, as per WHO ICD-10 nosology) cohort (n=57), the BECK depression scale and the "Reading the mind in the eyes" test were employed for the diagnosis of clinical symptoms, and for the evaluation of individual ToM skills, respectively. Wellbeing was quantified using the FANLCT scale. RESULTS: The wellbeing of service-users decreased significantly, in correlation with their defective emotion recognition abilities. Additionally, a low capacity for the correct perception of emotions in other people appears to significantly influence the social relationships status, with scores of 14.00 (10.00-18.50) at low capacity vs 23.00 (17.58-24.75) at normal capacity (Mann-Whitney U-test, p < 0.001). Our study findings indicate that a normal ability for a correct recognition of emotions in others is significantly and strongly correlated with adequate social relationships (Spearman r = 0.757, p < 0.05). CONCLUSION: Wellbeing is significantly correlated with the individual ability for a correct recognition of emotions in others.

Distribution of microRNAs associated with major depressive disorder among blood compartments.

OBJECTIVE: Major depressive disorder (MDD) is a recurrent disorder with an increasing incidence. Alterations in key signaling pathways of the nervous system, such as the Wnt and MAPK pathways, mediated through microRNAs (miRNAs) provide crucial information regarding the etiopathology of MDD. We aimed to analyze whether the heterogeneity of literature findings regarding differential expression of miRNAs in the blood could arise from their different distributions among blood compartments. METHODS: We performed a pilot study analyzing the differential expression of miR-26a, miR-494, miR-30c, miR-93, and miR-101 and investigated their levels in white blood cells, total plasma (TP), exosomes from plasma, and exosome depleted plasma (EDP) in patients with MDD before and after antidepressant treatment with escitalopram and in healthy controls. RESULTS: MiR-494 was more abundant in EDP, and miR-26a and miR-30c were predominantly more abundant in TP relative to other blood compartments. Moreover, miR-30c, miR-101, and miR-26a, were significantly downregulated in TP of patients with MDD compared with controls. After antidepressant treatment, only miR-494 was significantly differently expressed in EDP. CONCLUSIONS: This proof-of-principle study suggests that identifying the miRNA abundance in different blood compartments is crucial for biomarker development and could enrich the current knowledge regarding MDD pathophysiology.

The Relationship Between Type D Personality and the Complexity of Coronary Artery Disease.

PURPOSE: The relationship between personality traits and cardiovascular disease has gathered sustained interest over the last years, type -D personality (TDP) being significantly associated with coronary artery disease (CAD). However, data regarding the connection between the TDP and the severity of CAD disease is scarce. The aim of our study was to assess the relationship between TDP and the complexity of CAD, and to compare it with other sociodemographic and clinical features. PATIENTS AND METHODS: We conducted a cross-sectional case-control clinical-based study on 221 consecutive hospitalized patients with chest pain (60 ± 10.2 years; 131 men), referred for coronary angiography. RESULTS: TDP was identified in 42 (19%) patients, using the DS 14 scale. Symptomatology profile was evaluated using the SCL-90 scale. Syntax score was greater in the subgroup of patients with TDP in comparison to non-TDP subgroup (26.21±12.03 vs 15.49±8.89, respectively, p<0.001), and most of SCL-90 symptom dimensions have significantly higher levels in the subgroup of TDP with CAD patients (all p < 0.05). Smoking (ß=0.132, p=0.037), dyslipidemia (ß=0.149, p=0.013), Diabetes Mellitus (ß=232, p<0.001), NA dimension of TDP (ß=0.255, p<0.001) and SI (ß=0.279, p<0.001) dimension of TDP have a significant contribution to the complexity of CAD assessed by Syntax score. CONCLUSION: TDP was associated with a more complex CAD assessed by Syntax score, and may represent a dynamic interface between the biological and psychological vulnerabilities and the symptoms of CAD.

Proniosomal Gel for Topical Delivery of Rutin: Preparation, Physicochemical Characterization and In Vitro Toxicological Profile Using 3D Reconstructed Human Epidermis Tissue and 2D Cells.

Rutin (Rut) is a natural flavonol, well-known for its broad-spectrum of therapeutic effects, including antioxidant and antitumoral activities; still, it has a reduced clinical outcome due to its limited solubility in aqueous solutions. To overcome this drawback, this study proposes a novel formulation for rutin as a proniosomal gel for cutaneous applications. The gel was prepared by coacervation phase-separation method and complies with the standard requirements in terms of particle size (140.5 ± 2.56 nm), zeta potential (-27.33 ± 0.09 mV), encapsulation capacity (> 50%), pH (7.002 ± 0.18) and rheological properties. The results showed high biocompatibility of the gel on the 3D reconstructed human epidermis model characterized by increased viability of the cells and a lack of irritant and phototoxic potential. The evaluations on 2D cells confirm the preferential cytotoxic effect of Rut on melanoma cells (IC50 value = 8.601 µM, nuclear fragmentation) compared to normal keratinocytes. Our data suggest that the proniosomal gel is a promising drug carrier for Rut in the management and prevention of skin disorders.

The role of personality dimensions and trait anxiety in increasing the likelihood of suicide ideation in women during the perinatal period.

INTRODUCTION: Increasing amount of data reveal that suicide risk is a real phenomenon among perinatal women, determined by several other psychopathological conditions with depression being just one of them. This study aimed to investigate the role of personality dimensions on the occurrence of suicide ideation during the perinatal period. METHODS: A longitudinal prospective study was performed in pregnant women who were monitored at university-based obstetrical care units in our county. Recruited women were reassessed between 6 and 8 weeks into their postnatal period. Trait and state anxiety, five-factor based dimensions of personality, and depressive symptoms were assessed using established psychometric measures. Appropriate statistical analyses were conducted, depending on the distribution of variables. RESULTS: Significant levels of state anxiety (33.7% vs. 15.5%), depressive symptoms (19.8% vs. 8.5%), and suicide risk (13.9% vs. 6.3%) have halved in the postnatal period compared to the antenatal assessment. A lower level of education was associated with the presence of postnatal suicide ideation (p = .041), while an unemployed professional status was more frequent in pregnant women presenting antenatal suicide ideation (p = .021). Trait anxiety was predictive for the appearance of suicide ideation within the entire perinatal period assessed (p < .001 and p = .007, respectively). Agreeableness and conscientiousness predicted antenatal suicide ideation (p = .033 and p = .032, respectively). DISCUSSIONS: Different dimensions of personality may play a contributing role in the development of suicide ideation in perinatal women. Consequently, personality dimensions and trait anxiety, not only depressive symptoms, should be investigated when attempting to identify perinatal women at risk of suicide.

Evolution of Heart Rate Variability and Heart Rate Turbulence in Patients with Depressive Illness Treated with Selective Serotonin Reuptake Inhibitors.

Background and objectives: Major depressive disorder (MDD) and cardiovascular diseases (CVDs) represent serious and prevalent medical conditions. Autonomic nervous system (ANS) dysfunctions, expressed by parameters of heart rate variability (HRV) and heart rate turbulence (HRT), have been repeatedly associated with depression. The aim of our study was to identify potential HRV and HRT alterations in patients with MDD, before and after selective serotonin reuptake inhibitor (SSRI) therapy, and to observe any correlations between these parameters and the severity of depressive symptoms. Another aim was to evidence if there was a normalization or improvement of HRV and HRT parameters that paralleled the reduction of the intensity of depressive symptoms. Materials and Methods: We studied heart rate variability (HRV) and heart rate turbulence (HRT) in a sample of 78 patients, aged under 51 years, who were referred to our outpatient clinic between June 2017 and December 2019, for complaints in the context of a new onset major depressive disorder (MDD), before and after therapy with SSRIs. Results: By using 24 h Holter ECG monitoring, we evidenced alterations of HRV and HRT parameters, significantly correlated with the severity of depressive symptoms (p < 0.001), as assessed by the Montgomery-Åsberg Depression Rating Scale (MADRS). Our results indicated that these parameters improved following one and six months of SSRI therapy, when a partial or total remission of depressive symptoms was achieved (p < 0.001). Changes in HRV parameters were correlated with the reduction of the severity of depression. Conclusions: In our study group, we highlighted, through 24 h ECG Holter monitoring, frequent and clear HRV and HRT abnormalities that were statistically correlated with the severity of depressive symptoms. Furthermore, we were able to document a progressive improvement of these parameters, which corresponded with the improvement of depressive symptoms under SSRI therapy, when compared to the values measured before the commencement of antidepressant pharmacotherapy.

Left heart hypoplasia operated using double pulmonary arterial banding with double arterial duct stenting: A case report.

Hypoplastic left heart syndrome is a heterogeneous group of congenital cardiac malformations which associates hypoplastic/aplastic left ventricle, mitral and aortic valve, hypoplastic/atresia and severe aortic artery coarctation, and represents a medical-surgical emergency. We present a case of a newborn hospitalised in three clinics (two clinics from Timisoara and one from Vienna), and operated for hypoplastic left heart syndrome, without aortic coarctation, using a mixed technique cardiovascular repair surgery. The initial therapeutic conduct included maintaining the permeability of the arterial canal with prostaglandin E1. At the Vienna General Hospital, at the age of 17 days, bilateral banding of the pulmonary artery was performed and, at the age of 20 days, during the cardiac catheterisation, the Rashkind procedure (balloon atrial septostomy) was performed, with two stents being implanted in the arterial canal. Postoperative complications were postcardiotomy syndrome, pneumonia with Enterococcus faecalis and Stenotrophomonas maltophilia, sepsis with methicillin-resistant Staphylococcus aureus, coagulopathy, mixed anaemia, and metabolic acidosis. The patient died 1 month after the intervention due to cardiorespiratory arrest, bilateral congestive heart failure, left heart hypoplasia with shunt through the arterial canal and pulmonary artery banding, multiorgan failure, and severe secondary haemorrhagic disease. In conclusion, the initial cardiac surgical reconstruction consisted of a mixed technique, and anticoagulant medical treatment with heparin, antibiotics (bacterial endocarditis prophylaxis to be performed throughout life); postintervention hypoxic and infectious complications resulted in multiorgan failure and death.

Comparative Spectrographic Analysis of the Newborns' Cry in the Presence of Tight Intrapartum Nuchal Cord vs. Normal using the Neonat App. Preliminary Results.

Background and objectives: The objective of this study was to contribute to the evaluation of the newborn (NB) cry as a means of communication and diagnosis. Materials and Methods: The study implied the recording of the spontaneous cry of 101 NBs with no intrapartum events (control sample), and of 72 NBs with nuchal cord (study sample) from the "Bega" University Clinic of Obstetrics-Gynecology and Neonatology of Timisoara, Romania. The sound analysis was based upon: Imagistic highlighting methods, descriptive statistics, and data mining techniques. Results: The differences between the cry of NBs with no intrapartum events and that of NBs affected by nuchal cord are statistically significant regarding the volume unit meter (VUM) (p = 0.0021) and the peak point meter (PPM) (p = 0.041). Conclusions: While clinically there are no differences between the two groups, the cry recorded from the study group (nuchal cord group) shows distinctive characteristics compared to the cry recorded from the control group (eventless intrapartum NBs group).

Profiling undergraduate students from a Romanian medical university.

PURPOSE: Medical 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 METHODS: This 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). RESULTS: GM 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. CONCLUSION: The 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.

Modern molecular study of weight gain related to antidepressant treatment: clinical implications of the pharmacogenetic testing.

Antidepressant medication influences cellular lipogenesis, being associated with metabolic side effects including weight gain. Due to the increasing use of antidepressants in children and adolescents, their metabolic and endocrine adverse effects are of particular concern, especially within this pediatric population that appears to be at greater risk. Genetic factors with a possible influence on antidepressant's adverse effects include CYP [cytochrome P450 (CYP450)] polymorphisms. We target to evaluate the efficacy of the pharmacogenetic testing, when prescribing antidepressants, in correlation with the occurrence of adverse events and weight gain. Our research was performed between the years 2010 and 2016, in the University Clinic of Child and Adolescent Psychiatry, Timisoara, Romania. We recruited 80 patients, children and adolescents with depressive disorders. Our study sample was divided in two groups: G1 - 40 patients took treatment after pharmacogenetic testing, and G2 - 40 patients without pharmacogenetic testing before the treatment election. Our results show statistically significant differences concerning the weight gain for groups G1 (with pharmacogenetic testing) and G2 (without pharmacogenetic testing). The CYP genotype and the pharmacogenetic testing, for choosing the personalized antidepressant therapy in children and adolescents with depressive disorders, proved to be good predictors for the response to antidepressants and the side effects registered, especially for weight gain. The significant correlations between the CYP polymorphisms for group G2 (without pharmacogenetic testing) and the weight gain/body mass index (BMI) increase, as major side effects induced by antidepressants, proved the fact that the pharmacogenetic screening is needed in the future clinical practice, allowing for individualized, tailored treatment, especially for at-risk pediatric categories.

Neurobiological arguments for a pathogenic multifactorial disconnective model of cognitive disorders from Alzheimer's disease in elderly people.

Incidence of Alzheimer's disease (AD) in people over 75 years is much higher, and the progression of cognitive deficit become faster, leading to a decrease of quality of life for patients and their families. In this context, it is proposed a multifactorial pathogenic model of disconnected cognitive circuits, which is combined with genetic and vascular-cerebral vulnerability elements, allowing an aggressive progression of neurodegenerative factors, favoring onset of dementia. Data from research studies on animal model (rat) highlighted central role of cerebral cholinergic deficit (which is amplified by cerebral ischemia) on the background of apolipoprotein E4 (ApoE4) genotype, favoring multifactorial disconnected mechanisms, by excess of beta-amyloid (ß-A) or increase of vascular dysfunction. Depressive disorder, social stress and traumatic brain injury are favoring the excess in production of ß-A. Hippocampal structure disconnects the cognitive circuits, and from a neuropsychological point of view can be many patterns, which are correlated with neuroimaging (hippocampal atrophy, cerebral siderosis, white matter hyperintensity, ventriculomegaly) or biological (hyperhomocysteinemia) factors. Identifying the pathogenic model of multifactorial disconnectivity in the rapid evolution of cognitive deficit in patients with AD may create the premises for an early diagnosis and treatment, based on the biological, neuropsychological and clinical elements.
