Severe emotional stress constitutes a significant public-health concern associated with negative health outcomes. Although the clinical effects are well acknowledged, the specific biological mechanisms that translate emotional suffering into systemic disease remain incompletely understood. Psychological stress activates the sympathetic nervous system and hypothalamic–pituitary–adrenal axis, which directly target mitochondria and alter their bioenergetic and redox capacity. For this reason, this narrative review proposes that mitochondria serve as the primary subcellular link in the mind–body connection, as they play a pivotal role in converting neuroendocrine signals into cellular dysfunction. In particular, we focus on the concept of mitochondrial allostatic load (MALT), a framework explaining how the progressive decline in mitochondrial functions, from their initial adaptive roles in energy production, reactive oxygen species signaling, and calcium regulation, to being sources of inflammation and systemic damage, occurs when stress exceeds regulatory limits. We also, discuss how this transition turns mitochondria from adaptive responders into drivers of multi-organ disease. In subsequent sections, we examine diagnostic potentials related to MALT, including the use of biomarkers, such as growth differentiation factor 15, cell-free mitochondrial desoxyribonucleic acid, and functional respirometry. Furthermore, we evaluate mitochondria-targeted therapeutic strategies, encompassing pharmacological compounds, such as mitoquinone mesylate, Skulachev ions, and elamipretide, alongside lifestyle and psychological interventions. Here, we aim to translate MALT biology into clinical applications, positioning mitochondrial health as a target for preventing and treating stress-related disorders. We propose that MALT may serve as a quantifiable bridge between emotional stress and somatic disease, enabling future precision medicine strategies integrating mitochondrial care.

Background: Mental health conditions are one of the most significant public health issues. Psychoeducation is an organized, structured, and understanding transfer of knowledge about the disease and its treatment, incorporating inspirational and educational elements to allow patients to achieve better management of their disease and increased treatment adherence and effectiveness, especially for patients with schizophrenia. This review will consider studies that include adults suffering from schizophrenia or other psychotic disorders and their family members. In this scoping review, the rigor expected of all primary and secondary research will be guided by clear and consistent standards governing its design, regardless of the level of inquiry. The review will aims to map the currently available research in nurse-led psychoeducational programs conducted on these populations. Inclusion criteria: Adults suffering from schizophrenia or other psychotic disorders and their family members; patients and family members aged from 18 to 75 years old. Both experimental and quasi-experimental study designs, including randomised controlled trials, non-randomised controlled trials, before-and-after studies, interrupted time-series studies, analytical observational studies, and descriptive observational study designs. Intervention: a) psychoeducational interventions on patients suffering from schizophrenia and/or other psychotic disorders and their families, b) nurse-led psychoeducational interventions. Methods and analysis: The scoping review will be conducted following the Joanna Briggs Institute methodology for scoping reviews. Medline, Scopus and CINAHL databases will be searched for relevant studies. The reference list of the selected articles will be screened. Data will be summarised in a comprehensive narrative summary to highlight the following for each nurse-led intervention program: main features, setting, and target. Ethics and dissemination: This study does not require ethical approval. The study will be submitted to a peer reviewed journal, will be publicly disseminated and will be the topic of research presentations.

The increasing prevalence of emergency room (ER) visits for mental health concerns presents a significant challenge for healthcare systems. This study aimed to analyze the socio-demographic and clinical characteristics associated with frequent users of psychiatric consultations in the ER of Maggiore della Carità University Hospital in Novara, Italy. A retrospective observational study was conducted over a six-year period (2017–2022), including all psychiatric consultations recorded in a hospital database. Frequent users were defined as individuals undergoing at least three psychiatric consultations in the ER within a year. Univariable and multivariable logistic models were employed to identify significant socio-demographic and clinical predictors of frequent use. Of the 1565 individuals who received psychiatric consultations in the ER, 92 (5.88%) were identified as frequent users. Factors associated with higher ER utilization included being unmarried (aOR 1.35, 95% CI 1.02–1.79), younger age (aOR 1.32, 95% CI 1.02–1.72), homelessness, diagnosis of schizophrenia, substance use disorder (aOR 1.49, 95% CI 1.06–2.09), and ongoing psychopharmacological treatment (aOR 1.56, 95% CI 1.12–2.18). These findings highlight the need for targeted interventions to improve care continuity and community-based support for individuals at risk of frequent ER visits for psychiatric reasons.

Patients intoxicated with alcohol or other substances are often assessed and assisted in the context of the Emergency Department (ED) by emergency physicians, who usually require a psychiatric assessment. This study aims to analyse the characteristics of a sample of patients receiving a psychiatric consultation in the ED setting of the Maggiore della Carità University Hospital in Novara, Italy, in the period from 1 January 2021 to 31 December 2023, to find out whether and how patients screening positive for alcohol/drugs differ from those screening negative. Socio-demographic and clinical history information and clinical data related to the ED psychiatric consultations were extracted from the PsNet database, a collection of data extracted from the application that serves as the electronic medical record for patients accessing the ED. Statistical analyses were performed using SAS 9.4 and STATA version 17 software. Chi-square/Fisher tests, t-tests, and both univariate and multivariate logistic models were employed. Most of the findings regarding socio-demographic characteristics, symptoms observed during the 1362 psychiatric consultations, and treatments received by a total of 922 patients in the ED were consistent with the literature on this topic. However, some results only partially aligned with previous studies, particularly concerning the higher frequency of anxiety and psychotic symptoms, as well as cognitive impairments, observed in consultations for patients who tested negative for alcohol or substances. Interpreting these findings is complex and raises important questions, which may be addressed more effectively by expanding the sample size (extending the research to other EDs) and analysing its characteristics in greater detail. In this regard, improving diagnostic methods for detecting substance use through laboratory tests would also be beneficial.

Background: Internet-based psychological interventions provide accessible care to a wide range of users, overcoming some obstacles—such as distance, costs, and safety—that might discourage seeking help for mental issues. It is well known that psychological treatments and programs affect the body, as well as the mind, producing physiological changes that ought to be considered when assessing the efficacy of the intervention. However, the literature investigating changes in biomarkers specifically after internet-based psychological and mental health interventions has not yet extensively inquired into this topic. Objective: This systematic review aims to provide a synthesis of literature examining the effects of internet-based psychological interventions—targeting both clinical (mental and physical) and nonclinical conditions—on biomarkers. A secondary aim was to evaluate whether the biomarkers’ variations were related to a complementary modification of the psychological or physical symptoms or to a general improvement of the participants’ well-being. Methods: This review was conducted according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analysis) statement. A literature search was performed through 3 databases (PubMed, PsycINFO, and Scopus). Studies examining changes in biomarkers before and after internet-based psychological interventions or programs targeting both clinical and nonclinical samples were included, with no exclusion criteria concerning mental or physical conditions. Results: A total of 24 studies fulfilled the inclusion criteria. These studies involved individuals with psychiatric or psychological problems (n=6, 25%), those with organic or medical diseases (n=10, 42%), and nonclinical populations (n=8, 33%). Concerning psychiatric or psychological problems, cognitive behavioral therapy (CBT) and CBT-informed interventions showed partial effectiveness in decreasing glycated hemoglobin blood glucose level (n=1) and chemokines (n=1) and in increasing connectivity between the default-mode network and the premotor or dorsolateral prefrontal cortex (n=1). Among individuals with organic or medical diseases, studies reported a significant change in cardiac or cardiovascular (n=3), inflammatory (n=2), cortisol (n=2), glycated hemoglobin (n=2), and immune response (n=1) biomarkers after CBT and CBT-informed interventions, and mindfulness and stress management interventions. Lastly, mindfulness, CBT and CBT-informed interventions, and music therapy succeeded in modifying immune response (n=2), cortisol (n=1), α amylase (n=1), posterior cingulate cortex reactivity to smoking cues (n=1), and carbon monoxide (n=1) levels in nonclinical populations. In some of the included studies (n=5), the psychological intervention or program also produced an improvement of the mental or physical condition of the participants or of their general well-being, alongside significant variations in biomarkers; CBT and CBT-informed interventions proved effective in reducing both psychological (n=2) and physical symptoms (n=2), while a mindfulness program successfully lowered cigarette consumption in a nonclinical sample (n=1). Conclusions: Although further evidence is required, we hope to raise awareness on the potential impact of internet-based interventions on biomarkers related to mental and physical health.

Autistic symptoms represent a frequent feature in schizophrenia spectrum disorders (SSD). However, the prevalence and the cognitive and functional correlates of autistic symptoms in unaffected first-degree relatives of people with SSD remain to be assessed. A total of 342 unaffected first-degree relatives related to 247 outpatients with schizophrenia were recruited as part of the multicenter study of the Italian Network for Research on Psychoses (NIRP). Autistic features were measured with the PANSS Autism Severity Scale. Three groups of participants, defined on the presence and severity of autistic symptoms, were compared on a wide array of cognitive and functional measures. Of the total sample, 44.9% presented autistic symptoms; 22.8% showed moderate levels of autistic symptoms, which can be observed in the majority of people with SSD. Participants with higher levels of autistic symptoms showed worse performance on Working Memory (p = 0.014) and Social Cognition (p = 0.025) domains and in the Global Cognition composite score (p = 0.008), as well as worse on functional capacity (p = 0.001), global psychosocial functioning (p < 0.001), real-world interpersonal relationships (p < 0.001), participation in community activities (p = 0.017), and work skills (p = 0.006). A high prevalence of autistic symptoms was observed in first-degree relatives of people with SSD. Autistic symptoms severity showed a negative correlation with cognitive performance and functional outcomes also in this population and may represent a diagnostic and treatment target of considerable scientific and clinical interest in both patients and their first-degree relatives.

Hand eczema is one of the most frequent dermatological diseases, with an incidence increased during the COVID-19 pandemic. The impact on life quality is considerable, giving rise to the need for a psycho-dermatological approach. This is a Randomized Control Trial (RCT) evaluating, either by the dermatological or psychological point of view, the effectiveness of an emollient and rehydrating topical product (Rilastil Difesa Sterile® cream) versus a standard treatment (i.e. moisturizing basic cream) in a group of 51 healthcare workers suffering from hand eczema during the COVID-19 pandemic. The enrolled subjects were randomized into a treatment or a control arm, treated for 8 weeks, and monitored through a clinical score (HECSI) and questionnaires evaluating the impact of the pathology and treatment on quality of life (DLQI and QOLHEQ). A psychometric evaluation was performed using the SCL-90 R, OCI-R, and CPDI scales. Our data, despite not reaching the statistical significance, demonstrated that both the clinical and psychological scores decreased mostly in patients treated with Rilastil Difesa Sterile^® cream when compared to those treated with simple topical emollients. Moreover, we observed a high level of psychic suffering in dermatological patients and a parallel change in dermatological and psychological indicators, thus confirming their connection.
