Introduction: After a long period of obscurantism, a possible role of psychedelics in clinical practice has progressively become a tangible perspective during the last two decades. However, the resounding enthusiasm linked to such 'psychedelic renaissance' runs the risk to unduly minimize the possible hazards associated with these compounds, while expanding their alleged benefits to improbable panacea-like proportions. In order to avoid mystifying or demonizing the properties of 5-HT2a agonists on emotional grounds, this subject requires a strictly unprejudiced and cautious approach to the evidence.

The objective of this study (registered under number 2020 006) was to assess the internal consistency of the revised Mental Health Professional Culture Inventory (MHPCI) scale, which comprises 15 items, among mental health service workers in Romania. To examine the psychometric properties of the MHPCI questionnaire within the Romanian population, we employed two main methods: The partial credit model (PCM) and Exploratory factor analysis (EFA). A total of 94 individuals were interviewed, and among them, 71 provided complete responses to the questionnaire.

Connexins (Cxs) are fundamental in cell-cell communication, functioning as gap junction channels (GJCs) that facilitate solute exchange between adjacent cells and as hemichannels (HCs) that mediate solute exchange between the cytoplasm and the extracellular environment. Mutations in the GJB1 gene, which encodes Cx32, lead to X-linked Charcot-Marie-Tooth type 1 (CMTX1), a rare hereditary demyelinating disorder of the peripheral nervous system (PNS) without an effective cure or treatment. In Schwann cells, Cx32 HCs are thought to play a role in myelination by enhancing intracellular and intercellular Ca signaling, which is crucial for proper PNS myelination.

Objective: Insomnia can be a contributing factor, a comorbid disorder, or a transdiagnostic element to several mental disorders, including mood disorders (MDs). A recent meta-analysis has already shown the effectiveness of cognitive behavioral treatment (CBT) for insomnia that is comorbid with MDs. This work aimed to systematically review data on pharmacological insomnia treatment in the context of MDS.

Objective: Resilience is a complex process of adaptation to new conditions that would permit a positive outcome after adversities, traumas or other sources of stress. However, despite the growing interest in this topic, there is no universally accepted definition and no comprehensive bio-behavioural model. This systematic review aims to provide an overview of the main biological models that have been theorized to date, with a focus on new alternative theories to improve our understanding of the mechanisms underlying the development and strengthening of resilience, with potential implications for the prevention of some psychopathological disorders.

Introduction: Post-traumatic stress disorder (PTSD) is a disabling psychiatric condition with a worldwide prevalence between 6% and 9%, and more common in the female than in the male sex. The aim of this paper is to review and comment on the different factors that might explain the discrepancies in the pharmacological management of women and men.

Areas Covered: The available literature shows that there exists a vulnerability of women to develop PTSD that may depend on neurobiological as well as environmental/cultural factors.

Ataxia-telangiectasia (A-T) is a rare disorder caused by genetic defects of A-T mutated (ATM) kinase, a key regulator of stress response, and characterized by neurodegeneration, immunodeficiency, and high incidence of cancer. Here we investigated NK cells in a mouse model of A-T (Atm) showing that they are strongly impaired at killing tumor cells due to a block of early signaling events. On the other hand, in Atm littermates with thymic lymphoma NK cell cytotoxicity is enhanced as compared with ATM-proficient mice, possibly via tumor-produced TNF-α.

Stable cell pools have the advantage of providing a definite, consistent, and reproducible transmission of a transgene of interest, compared to transient expression from a plasmid transfection. Stably expressing a transgene of interest in cells under induction is a powerful way to (switch on and) study a gene function in both in vitro and in vivo assays. Taking advantage of the ability of lentivirus (LV) to promote transgene delivery, and genomic integration and expression in both dividing and nondividing cells, a doxycycline-inducible transfer vector expressing a bicistronic transgene was developed to study the function of connexins in HeLa DH cells.

Objective: Recent evidence highlights that different agents may trigger immune-mediated processes involved in the pathophysiology of different neuropsychiatric conditions. Given the limited information on obsessive-compulsive disorder (OCD), the present study aimed at assessing current/past infections and plasma levels of vitamin D, vitamin B12, folic acid, homocysteine and common peripheral inflammatory markers in a group of OCD outpatients.

Method: The sample included 217 adult outpatients with an OCD diagnosis according to the DSM-5 criteria.

Article Synopsis
  • Mental disorders are a major global health issue, with depression projected to be the leading contributor to the disease burden by 2030, especially worsened by the COVID-19 pandemic's impact on mental health in adolescents.
  • The pandemic has led to long-term effects known as "long-COVID," which include cognitive and psychological symptoms linked to neuroinflammation caused by widespread inflammation.
  • Research suggests that the endocannabinoid system (ECS), particularly through the cannabinoid type-2 receptor (CB2R), may offer new treatment options for depression and anxiety, with a focus on β-caryophyllene (BCP) for its anti-inflammatory and antioxidant benefits.

Article Synopsis
  • The study aimed to explore the prevalence of food addiction (FA) in a sample of 842 patients seeking help from nutritionists for weight loss, focusing on their eating habits.
  • Results showed a 15.3% prevalence of FA, with higher rates in overweight and obese individuals, and significant differences in weight loss attempts and eating patterns between those with and without FA.
  • The findings suggest that FA may contribute to obesity and relate to certain psychological conditions, highlighting the need for further investigation despite its controversial diagnosis.

The present paper is the personal narration of the author reviewing her scientific pathways that led her toward the study of oxytocin. My work began with a pioneering study showing a decreased number of the serotonin transporter proteins in romantic lovers. This unexpected finding promoted my interest in the neurobiology of human emotions and feelings, and significantly shifted my research focus from diseases to physiological states that underlie "love.

Converging, albeit scattered data mainly gathered in animals indicate that the neurotrophin brain-derived neurotrophic factor (BDNF) and the nonapeptide oxytocin (OT) interact in a cooperative way. Data in humans are really limited and indirect. Therefore, the aim of the present study was to explore the possible existence of a link between OT and BDNF in humans, by means of two peripheral markers, the platelet-poor-plasmatic-BDNF (PPP-BDNF) and the platelet BDNF (PLT-BDNF) and OT levels.

Objective: The present study explores, retrospectively, the link between anti-vaccination attitude and vaccination intentions and extends this relationship to the effect of media consumption style on attitude.

Method: Generalized linear mixed-models were used to estimate vaccination intentions (related to each of the four available vaccines at the time of the survey) relying on anti-vaccination attitude measured using the Italian translation of the Vaccination Attitude Examination (VAX) scale. Multiple linear regression was used to estimate which media type and which consumption frequency were responsible for variation in the anti-vaccination attitude.

Background: Diagnostic criteria are not always useful to discriminate major depression with anxious distress (ADS-D; Diagnostic and Statistical Manual for Mental Disorders, version-5 [DSM-5] criteria) from mixed depression (Koukopoulos' criteria; KMX-D). So, clinicians need alternative tools to improve their diagnostic ability and to choose the most appropriate treatment. The aim of the present study is to identify socio-demographic and clinical features that discriminate patients with ADS-D from those with KMX-D.
