Main Biological Models of Resilience.

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. Method: This review was conducted according to PRISMA guidelines and includes 185 studies published in English in PubMed and Embase up to December 2023. Results: Most studies use the stress-related model, which conceptualizes resilience as the absence of symptoms after the stressful event and mainly deal with the differences between stress-prone and resilient phenotypes in animals exposed to stress. However, the results of this search seem to suggest that resilience might be an independent construct with biological bases rooted in the stress system and the social brain, and widely sculptured by individual and environmental factors, especially early life events and affiliation. Conclusions: This work contributes to ongoing efforts to understand the intricate mechanisms of resilience, while highlighting the potential of improving social relationships since our birth to promote coping strategies towards stress and traumas, and even a peaceful world.

Plasma and Platelet Brain-Derived Neurotrophic Factor (BDNF) Levels in Bipolar Disorder Patients with Post-Traumatic Stress Disorder (PTSD) or in a Major Depressive Episode Compared to Healthy Controls.

Post-traumatic stress disorder (PTSD) is a highly disabling mental disorder arising after traumatism exposure, often revealing critical and complex courses when comorbidity with bipolar disorder (BD) occurs. To search for PTSD or depression biomarkers that would help clinicians define BD presentations, this study aimed at preliminarily evaluating circulating brain-derived-neurotrophic factor (BDNF) levels in BD subjects with PTSD or experiencing a major depressive episode versus controls. Two bloodstream BDNF components were specifically investigated, the storage (intraplatelet) and the released (plasma) ones, both as adaptogenic/repair signals during neuroendocrine stress response dynamics. Bipolar patients with PTSD (n = 20) or in a major depressive episode (n = 20) were rigorously recruited together with unrelated healthy controls (n = 24) and subsequently examined by psychiatric questionnaires and blood samplings. Platelet-poor plasma (PPP) and intraplatelet (PLT) BDNF were measured by ELISA assays. The results showed markedly higher intraplatelet vs. plasma BDNF, confirming platelets' role in neurotrophin transport/storage. No between-group PPP-BDNF difference was reported, whereas PLT-BDNF was significantly reduced in depressed BD patients. PLT-BDNF negatively correlated with mood scores but not with PTSD items like PPP-BDNF, which instead displayed opposite correlation trends with depression and manic severity. Present findings highlight PLT-BDNF as more reliable at detecting depression than PTSD in BD, encouraging further study into BDNF variability contextually with immune-inflammatory parameters in wider cohorts of differentially symptomatic bipolar patients.

Post-traumatic Stress and Depressive Symptoms in Women With Ovarian Cancer 3-6 Months After Diagnosis.

BACKGROUND/AIM: The potentially traumatic role of severe life-threatening medical conditions is still debated in psychiatry and not yet recognized, particularly among post-traumatic stress disorders. However, increasing evidence suggests the psychopathological impact of severe medical conditions related to their poor prognosis, high lethality, treatments heaviness and invasiveness. Ovarian cancer (OC) is one of the malignancies with the highest mortality and the aim of this study was to investigate post-traumatic stress and depressive symptoms in women 3 to 6 months after diagnosis. PATIENTS AND METHODS: A sample of 83 women diagnosed with OC at different stages (from AI to IV) was recruited and assessed by means of the: Structural Clinical Interview for Mental Disorders according to DSM-5 (SCID-5), Trauma and Loss Spectrum Self-Report (TALS-SR), Impact Event Scale-Revised (IES-R), Hamilton Rating Scale for Depression (HAM-D), Mood Spectrum-Self Report (MOOD-SR), Work and Social Adjustment Scale (WSAS). RESULTS: Full data on the psychiatric assessments were available for 45 patients: 13 (28.9%) patients reported a diagnosis of PTSD. Patients with PTSD reported statistically significant higher depressive symptoms and more severe impact on work and social functioning compared to those without PTSD. CONCLUSION: Our results highlight the need to carefully assess the potentially traumatic burden of a diagnosis of OC and its association with depressive symptoms for their impact on patients' global functioning, in order to provide appropriate preventive and therapeutic interventions.

The relationship between peritraumatic distress, mental health symptoms, and functioning impairment in healthcare workers during the COVID-19 emergency.

OBJECTIVE: Healthcare workers (HCWs) were considered a population at risk for developing psychiatric symptoms during the COVID-19 pandemic, such as anxiety, depression, and post-traumatic stress disorder (PTSD). Peritraumatic distress is associated with post-traumatic psychopathological symptoms; however, little is known about how it may affect functioning. The study aimed at evaluating the level of peritraumatic distress in a sample of HCWs during the first wave of the COVID-19 pandemic and at examining the relationship between peritraumatic distress, mental health symptoms, and functioning impairment. METHODS: A sample of 554 frontline HCWs were consecutively enrolled in major university hospitals and community services in Italy. The PDI, IES-R, PHQ-9, and GAD-7 were used to assess peritraumatic distress, symptoms of PTSD, depression, and anxiety, respectively, and the WSAS to investigate functioning impairment. PDI scores were higher among females, community services, physicians, and nurses. Furthermore, the PDI correlated significantly with the GAD-7, PHQ-9, IES-R, and WSAS. RESULTS: In a mediation analysis, the direct effect of PDI on WSAS and the indirect effects through the PHQ-9 and IES-R were statistically significant (P < .001). CONCLUSION: Peritraumatic distress reported by HCWs was associated with symptoms of PTSD, depression, and anxiety, but the association with reduced functioning may be only partially mediated through symptoms of depression and PTSD.

Post-traumatic stress disorder and post-traumatic stress symptoms in patients with systemic autoimmune diseases during the COVID-19 pandemic.

OBJECTIVES: The COVID-19 outbreak led to an increase in mental disorders, particularly post-traumatic stress disorder (PTSD), in the general population and especially in high-risk populations such as patients with rheumatologic conditions. Although these latters are considered vulnerable to developing PTSD, few specific data have been particularly reported in the framework of the pandemic. The aim of the present study was to investigate PTSD and post-traumatic stress symptoms (PTSS) in a sample of patients with systemic autoimmune disease (SAD), followed in the framework of a prospective observational study during the pandemic. METHODS: The PERMAS project is a prospective observational study including patients with SAD and involving the Rheumatology and the Psychiatric Clinics of the Azienda Ospedaliero Universitaria Pisana (AOUP, Pisa, Italy) and the Institute of Management of the Scuola Superiore Sant'Anna (Pisa, Italy). The assessments included: a data-sheet for sociodemographic and clinical characteristics; the Trauma and Loss Spectrum-Self Report (TALS-SR) and the Impact of Event Scale-Revised (IES-R), for PTSD and PTSS; the 36-item Short Form Survey (SF-36) to assess quality of life. RESULTS: The total sample consisted of 252 patients with SAD, including 131 with connective tissue disease, 101 with arthritis and 20 with systemic vasculitis. The diagnostic groups differed significantly in age (p<0.001), gender (p<0.001), prevalence of full-blown and partial PTSD (p=0.001), and other psychopathologic variables. Connective tissue disease and SF-36 were significantly associated with the TALS-SR scores in both univariate (p<0.001) and multivariate (p<0.025; p<0.001) analyses. CONCLUSIONS: Patients with SAD, and, in particular, patients with connective tissue diseases reported an increased risk of developing stress-related psychopathological symptoms, indicating the need for special psychological monitoring of this high-risk group.

Emotional Dysregulation and Post-Traumatic Stress Symptoms: Which Interaction in Adolescents and Young Adults? A Systematic Review.

Emotional dysregulation (ED) has recently been conceptualized as a transnosographic entity in major mental disorders, and increasing evidence has suggested association between ED and post-traumatic stress symptoms (PTSS), though the nature of this association is unclear. The aim of the present review was to examine the possible interplay between ED and trauma exposure in the literature, as well as a possible role for the comorbidity of PTSD or PTSS in adolescents and young adults. In particular, we explored whether ED may represent a risk factor for PTSD or, conversely, a consequence of traumatic exposure. This systematic review was conducted according to PRISMA 2020 guidelines in three databases (PubMed, Scopus, and Embase). The 34 studies included showed a wide heterogeneity in terms of the populations selected and outcomes examined. Most studies used the Difficulties in Emotion Regulation Scale (DERS) and examined the relationship between ED, trauma, and psychopathological manifestations after the occurrence of trauma, with a focus on child abuse. Although current data in the literature are heterogeneous and inconclusive, this research highlights the role of ED as a mechanism that may mediate vulnerability to PTSD, but also as a predictor of severity and maintenance of typical, atypical, or associated PTSD symptoms, suggesting prevention programs for PTSD and other mental disorders should support the development of emotion regulation strategies.

Acute stress symptoms in general population during the first wave of COVID lockdown in Italy: Results from the COMET trial.

BACKGROUND: The coronavirus disease of 2019 (COVID-19) pandemic is an unprecedented traumatic event that has severely impacted social, economic, and health well-being worldwide. The COvid Mental hEalth Trial was specifically designed to evaluate the impact of the COVID-19 pandemic and its containment measures on the mental health of the Italian general population in terms of COVID-19-related acute stress disorder (ASD) symptoms. METHODS: The present cross-sectional study is based on an online survey carried out in the period March-May 2020. Italian general adult population was invited to compile an anonymous survey, which included the severity of acute stress symptoms scale/National Stressful Events Survey Short Scale to investigate the occurrence and severity of ASD symptoms. RESULTS: The final sample consisted of 20,720 participants. During the lockdown, subjects with pre-existing mental health problems reported a statistically significant higher risk of acute post-traumatic symptoms compared to the general population (B: 2.57; 95% CI:2.04-3.09; p < .0001) and health care professionals (B: .37; 95% CI: .02-0.72; p < .05). According to multivariate regression models, the levels of acute post-traumatic symptoms (p < .0001) were higher in younger and female respondents. Social isolation and sleep disorder/insomnia represented positive predictors of acute stress (B = 3.32, 95% CI = 3.08-3.57). CONCLUSIONS: Concerns about the risk of infection as well as social isolation caused a higher incidence of acute post-traumatic stress symptoms that may predict the subsequent development of post-traumatic stress disorder symptoms in the long term.

Decreased Levels of Vitamin D in Bipolar Patients.

Recently, vitamin D is considered a pleiotropic hormone, and as such, it has also become a topic of renewed interest in neuropsychiatry for its proposed role in the aetiology and pathophysiology of different psychiatric conditions, including mood disorders (MDs). This seems particularly crucial while considering the relatively high and often neglected prevalence of hypovitaminosis D in the general population and in specific groups, such as patients suffering from the most common type of MDs, which are major depression (MDD) and bipolar disorders (BDs). Therefore, in view of the controversial literature and findings on this topic and its potential therapeutic implications, the present study aimed at evaluating vitamin D levels in the plasma of a sample of inpatients fulfilling the DSM-5 criteria for mood episodes within BDs. The clinical picture was assessed by means of specific rating scales. The results showed that the vitamin D levels (mean ± SD, nM/L) of the bipolar patients of our sample were significantly lower (14.58 ± 11.27 nmol/L) than the normative values (>30 nmol/L). Eleven patients had sufficient values and only 4 had optimal, while 19 showed insufficient, 18 critical, and 17 severely critical levels. No differences emerged according to different socio-demographic or clinical features. In our opinion, the present findings strengthen previous research highlighting decreased vitamin D levels in bipolar patients and support the role of this pleiotropic hormone in BDs. Nevertheless, further studies should follow to corroborate the data of this preliminary study and to address the potential benefits of vitamin D supplementation in the treatment of MDs.

Internet Use Amongst Professional Tennis Players.

Objective: Next to its well-known benefits, Internet may trigger harmful consequences due to its abuse, thus delineating clinical pictures that are similar to abuse disorders, such as Problematic Internet Use (PIU). The matter becomes more elusive for sportsmen, as data regarding PIU in this specific group are scarce, particularly for tennis players. Therefore, our aim was to assess the prevalence and the features of PIU in a sample of either in current activity or retired professional tennis players, as compared with healthy controls. Method: Twenty-five professional tennis players were evaluated during two events held in two different European countries and were matched to an equal number of healthy subjects who were not performing any agonistic sport. The characteristics of Internet use were assessed by a specific instrument we developed (QUNT). Statistical analyses were carried out to evaluate both demographic and QUNT features and the possible intergroup differences. Results: Retired athletes presented statistically significant lower scores compared to both athletes in current activity and control subjects in the "Time spent online" and in the "Addiction to pornography" domains. Athletes in current activity presented statistically significant higher scores compared to retired athletes in the "Ludopathy" and Total score domains. Male athletes had a statistically significant lower score in the "Addiction to pornography" domain compared to both female and male healthy controls. Conclusions: Tennis players frequently indulge in the use of Internet facilities, particularly those in current activity, thus potentially being more vulnerable to PIU. Men and women seem to use Internet for different activities. The lifestyle that professional tennis players are obliged to follow might provide an explanation of our findings.

Metabolic and Inflammatory Response in Post-Traumatic Stress Disorder (PTSD): A Systematic Review on Peripheral Neuroimmune Biomarkers.

Several heterogeneous pathophysiology pathways have been hypothesized for being involved in the onset and course of Post-Traumatic Stress Disorder (PTSD). This systematic review aims to summarize the current evidence on the role of inflammation and immunological dysregulations in PTSD, investigating possible peripheral biomarkers linked to the neuroimmune response to stress. A total of 44 studies on the dysregulated inflammatory and metabolic response in subjects with PTSD with respect to controls were included. Eligibility criteria included full-text publications in the English language, human adult samples, studies involving both subjects with a clinical diagnosis of PTSD and a healthy control group. The research was focused on specific blood neuroimmune biomarkers, namely IL-1ß, TNF-α, IL-6 and INF-γ, as well as on the potential harmful role of reduced antioxidant activity (involving catalase, superoxide dismutase and glutathione peroxidase). The possible role of the inflammatory-altered tryptophan metabolism was also explored. The results showed conflicting data on the role of pro-inflammatory cytokines in individuals with PTSD, and a lack of study regarding the other mediators investigated. The present research suggests the need for further studies in human samples to clarify the role of inflammation in the pathogenesis of PTSD, to define potential peripheral biomarkers.

Pharmacological Treatment of Acute Psychiatric Symptoms in COVID-19 Patients: A Systematic Review and a Case Series.

Delirium and psychomotor agitation are relevant clinical conditions that may develop during COVID-19 infection, especially in intensive care unit (ICU) settings. The psychopharmacological management of these conditions is receiving increasing interest in psychiatry, considering hyperkinetic delirium as one of the most common neuropsychiatries acute consequences in COVID-19 recovery patients. However, there are no actual internationally validated guidelines about this topic, due to the relatively newly introduced clinical condition; in addition, a standardized psychopharmacologic treatment of these cases is a complex goal to achieve due to the risk of both drug-drug interactions and the vulnerable conditions of those patients. The aim of this systematic review and case series is to evaluate and gather the scientific evidence on pharmacologic handling during delirium in COVID-19 patients to provide practical recommendations on the optimal management of psychotropic medication in these kinds of patients. The electronic databases PubMed, Embase and Web of Science were reviewed to identify studies, in accordance with the PRISMA guidelines. At the end of the selection process, a total of 21 studies (n = 2063) were included. We also collected a case series of acute psychomotor agitation in COVID-19 patients hospitalized in ICU. Our results showed how the symptom-based choice of the psychotropic medication is crucial, and even most of the psychotropic drug classes showed good safety, one must not underestimate the possible drug interactions and also the possible decrease in vital functions which need to be strictly monitored especially during treatment with some kinds of molecules. We believe that the evidence-based recommendations highlighted in the present research will enhance the current knowledge and could provide better management of these patients.
