Essential Oil Constituents as Anti-Inflammatory and Neuroprotective Agents: An Insight through Microglia Modulation.

Microglia are key players in the brain's innate immune response, contributing to homeostatic and reparative functions but also to inflammatory and underlying mechanisms of neurodegeneration. Targeting microglia and modulating their function may have therapeutic potential for mitigating neuroinflammation and neurodegeneration. The anti-inflammatory properties of essential oils suggest that some of their components may be useful in regulating microglial function and microglial-associated neuroinflammation. This study, starting from the ethnopharmacological premises of the therapeutic benefits of aromatic plants, assessed the evidence for the essential oil modulation of microglia, investigating their potential pharmacological mechanisms. Current knowledge of the phytoconstituents, safety of essential oil components, and anti-inflammatory and potential neuroprotective effects were reviewed. This review encompasses essential oils of Thymus spp., Artemisia spp., Ziziphora clinopodioides, Valeriana jatamansi, Acorus spp., and others as well as some of their components including 1,8-cineole, ß-caryophyllene, ß-patchoulene, carvacrol, ß-ionone, eugenol, geraniol, menthol, linalool, thymol, α-asarone, and α-thujone. Essential oils that target PPAR/PI3K-Akt/MAPK signalling pathways could supplement other approaches to modulate microglial-associated inflammation to treat neurodegenerative diseases, particularly in cases where reactive microglia play a part in the pathophysiological mechanisms underlying neurodegeneration.

Choosing a COVID-19 vaccination site might be driven by anxiety and body vigilance.

Background: The occurrence of COVID-19 led to the rapid development of several vaccines which were distributed around the world. Even though there had been a vast amount of information about both virus and vaccination, this process was potentially related to increased anxiety and thus affected the vaccination process. Objective: The present study examined anxiety levels and body vigilance in subjects reporting for COVID-19 vaccination at different vaccination sites. Methods: Instruments used included general socio-demographic questionnaires and specifically constructed ones such as generalized anxiety disorder (GAD), body vigilance scale (BVS), and coronavirus anxiety scale (CAS). Results: A total of 227 subjects enrolled in the study reported mild GAD and CAS scores and relatively low scores on BVS. When the subjects were divided according to a vaccination site (under supervision and non-supervised), it turned out that subjects vaccinated under supervision were more anxious (higher GAD and CAS) and had their body vigilance increased. Conclusion: In conclusion, there is a need for highlighting the importance of efficient planning and organization of vaccination process, since to a certain extent it is driven by both anxiety and body vigilance.

The Co-Occurrence of Post-Traumatic Stress Disorder and Depression in Individuals with and without Traumatic Brain Injury: A Comprehensive Investigation.

Post-traumatic stress disorder (PTSD) is a prevalent psychiatric disorder that often occurs following war trauma. Despite its high prevalence, there is still a lack of comprehensive understanding regarding the mechanisms underlying its progression and treatment resistance. Recent research has shed light on the biological basis of PTSD, with neuroimaging studies revealing altered brain connectivity patterns in affected individuals. In war contexts, traumatic brain injury (TBI) is a common occurrence and is associated with a high prevalence of PTSD. This study aimed to compare the severity of PTSD and depression in patients with and without a history of TBI to shed light on the impact of comorbid TBI on the presentation of PTSD symptoms. To achieve this goal, a cross-sectional study was conducted involving a sample of 60 outpatients who were diagnosed with both PTSD and Depressive Disorder. The inclusion criteria required participants to meet the diagnostic criteria for both disorders using validated tools. The severities of PTSD and depressive symptoms were assessed using scales that have been widely used and validated in previous research. By utilizing these standardized assessment tools, this study aimed to ensure the reliability and validity of the obtained data. The results of this study revealed that patients with comorbid PTSD and TBI exhibited a significantly higher severity of PTSD symptoms compared to those with PTSD only. Specifically, the comorbid group demonstrated higher ratings of symptom intensity across all symptom clusters. These findings are consistent with previous research that has highlighted the impact of comorbid TBI on the intensity and persistence of PTSD symptoms. When controlling for PTSD severity, no significant differences were observed in the severity of depressive symptoms between the two groups. This suggests that the increased depressive symptoms observed in the comorbid group may be primarily driven by the presence of more intense PTSD symptoms rather than TBI per se. The findings highlight the need for an accurate diagnosis of TBI in individuals with PTSD to guide appropriate treatment interventions. Further research is warranted to delve into the underlying mechanisms that contribute to the interaction between TBI and PTSD and to develop targeted interventions for individuals with comorbid PTSD and TBI.

Possible impact of COVID-19 pandemic and lockdown on suicide behavior among patients in Southeast Serbia.

Individuals with serious mental illness are more affected by emotional reactions, including suicidal behavior due to COVID-19 and psychosocial consequences of pandemic. The current cross-sectional study aimed to explore the possible association of COVID-19 and suicidal behavior (suicide ideation and attempt) before and during pandemic-associated lockdown in Serbia. We retrospectively reviewed the clinical records of 104 adult psychiatric inpatients admitted at Psychiatric Clinic, University Clinic Center Nis, Serbia, after ending lockdown and compared the obtained results with 181 adult psychiatric inpatients admitted during the same period in 2019 and 2018. Suicide ideation were more frequent in 2020 comparing with 2019 and 2018 (25 vs 12.5%, vs 9.41%; p < 0.05). Around 28% of patients with suicide attempts were exposed daily to the information related to COVID-19 coming from social media, while this frequency was significantly lower, only 7.55% (p < 0.1), among patients with no suicide ideation or attempts. Adjustment disorder was more frequent among patients with suicide attempts in comparison to the patients with suicide ideation (32 vs 11%), especially in patients without suicide ideation and attempts (32 vs 0%, p < 0.001). Of all studied patients with suicide attempts during 2020, 60% were not in the previous psychiatric treatment before admission.

Predictors of Mortality in Long-Term Follow-Up of Patients with Terminal Alcoholic Cirrhosis: Is It Time to Accept Remodeled Scores?

OBJECTIVE: To identify the prognostic score that is the best predictor of outcome in patients hospitalized with decompensated liver cirrhosis. MATERIAL AND METHODS: In this prospective study, 126 patients were enrolled and followed up for 29 months. For each patient, prognostic scores were calculated; these included the Child-Turcotte-Pugh score (CTP score), CTP creatinine-modified I score, CTP creatinine-modified II score, Model for End-Stage Liver Disease (MELD score), MELD model for end-stage liver disease sodium-modified score, Integrated MELD score, updated MELD score, United Kingdom MELD, and the MELD score remodeled by serum sodium index (MESO index). Cox regression analysis was used to assess the ability of each of the scores for predicting mortality in patients with alcoholic cirrhosis. Their discriminatory ability was evaluated using receiver operating characteristic (ROC) curve analysis. RESULTS: The updated MELD score had the highest predictive value (3.29) among the tested scores (95% CI: 2.26-4.78). ROC curve analysis demonstrated that the MELD score of 22.50 (AUC = 0.914, 95% CI: 0.849-0.978; p < 0.001) had the best discriminative ability for identifying patients with a high risk of mortality; the next best was the MESO index of 16.00 (AUC = 0.912, 95% CI: 0.847-0.978; p < 0.001). CONCLUSION: The risk of mortality was highest in patients with the highest updated MELD score, and those with MELD scores >22.50 and a MESO index >16.00.

A preview of the efficiency of systemic family therapy in treatment of children with posttraumatic stress disorder developed after car accident.

BACKGROUND/AIM: Traumatic stress refers to physical and emotional reactions caused by events which represent a life threat or a disturbance of physical and phychological integrity of a child, as well as their parents or gaerdians. Car accidents are the main cause of posttraumatic stress disorder (PTSD) in children. The aim of this study was to preview clinical efficiency of systemic family therapy (SFT) as therapy intervention in treatment of children with posttraumatic stress disorder (PTSD) traumatized in car accident under identical circumstances of exposure. We pointed out the importance of specific family factors (family cohesion and adaptability, emotional reaction of the parents) on PTSD clinical outcome. METHODS: The sample of this clinical observational study included 7-sixth grade pupiles--5 boys and 2 girls, aged 13. All of the pupils were involved in car accident with one death. Two groups were formed--one group included three children who were involved in 8 SFT sessions together with their families. The second group included 4 children who received an antidepressant sertraline in the period of three months. RESULTS: Two months after the car accident, before the beginning of the therapy, all of the children were the members of rigidly enmeshed family systems, considering the high average cohesion scores and the low average adaptability scores on the FACES III. Three months after the received therapy, having evaluated the results of the therapeutic approaches, we established that the adaptability scores of the families included in the SFT were higher than the scores of the families of the children who received pharmacotherapy with one boy still meeting the criteria for PTSD. CONCLUSION: Systemic family therapy was efficient in the treatment of children with PTSD, traumatized in car accident. Therapy efficiency was higher when both parents and children were included in SFT than in the case when they were not included in the family therapy. The change in the functioning of the family systems was not accidental or simply time-dependant, but it depended on the therapy which was applied and the increased level of family adaptability as the main risk factor of retraumatization.

Disturbed family functioning in patients suffering from posttraumatic stress disorder.

AIM: To investigate whether the presence of posttraumatic stress disorder (PTSD) symptomatology is related to specific family problems. METHODS: The study included 94 subjects who were divided into three groups: a group with posttraumatic stress disorder (based on PCL for DSM-IV National Center for PTSD) (N=31), a group with problems in postwar functioning but without posttraumatic stress disorder (N=33), a group of subjects who were mobilized but with no combat exposure experience (N=30). The first and the second group had the experience of combat exposure. The first group was experimental, being diagnosed with PTSD. The second and the third group were control groups (the first and the second control group). The groups were compared by intensity and quality of family dysfunction, in relation to parameters, determined by specific instruments used in this research. RESULTS: The subjects with the experience of combat exposure had the problems in family functioning independently of the existence of PTSD diagnosis. Many of these problems were caused by the damage of combat experience. We also found a high level of secondary traumatization among other family members. CONCLUSION: The combat experience causes problems in postwar family functioning of combatants independently of PTSD diagnosis being confirmed. It is, therefore, necessary to help all of the combatants and their families reintegrate, regardless of their PTSD diagnosis.

[Correlation of adverse childhood experiences with psychiatric disorders and aggressiveness in adulthood].

BACKGROUND/AIM: Consequences of individual adverse childhood experiences for adult mental health have been precisely studied during past decades. The focus of past research was mainly on childhood maltreatment and neglect. The aim of this paper was to determine association between multiple adverse childhood experiences and psychiatric disorders, as well as their correlation to the degree and type of aggressiveness in adult psychiatric patients. METHODS: One hundred and thirteen psychiatric outpatients were divided into three diagnostic groups: psychotics, non-psychotics and alcoholics and compared with fourty healthy individuals. Adverse childhood experiences data were gathered retrospectively, using the Adverse childhood experiences questionnaire and explanatory interview. Aggressiveness was assessed using Buss-Perry Aggression Questionnaire. The Student's t test, ANOVA and correlational analysis were used for evaluation of statistical significance of differences among the groups. A value p < 0.05 was considered statistically significant. RESULTS: Our results showed that the mean number of adverse childhood experiences in each group of psychiatric patients, as well as in the whole group of patients, was statistically significantly higher than in the group of healthy individuals (p < 0.001); there was a statistically significant difference in score of physical aggressiveness between the patients exposed to adverse childhood experiences and those who were not exposed to them (p < 0.05); scores of physical aggressiveness were in positive correlation with the number of adverse childhood experiences (p < 0.05). The highest mean score of adverse childhood experiences was evidenced in the group of patients with psychotic disorders. CONCLUSION: Multiple adverse childhood experiences are significantly associated with psychotic disorders, nonpsychotic disorders and alcohol dependence in adulthood and their presence is important morbidity risk factor for psychiatric disorders. They are in positive correlation with physical aggressiveness of the patients from these diagnostic groups.

[Assessment of clinical depression comorbid with posttraumatic stress disorder].

BACKGROUND/AIM: Comorbidity of the posttraumatic stress disorder (PTSD) and depression is often recognized in the clinical practice. The aim of the paper was to determine the severity of depression and the group of symptoms which are the most prominent in clinical depression comorbid with PTSD. METHODS: Totally 60 patients were assessed and divided into the experimental and control group using the Structured Clinical Interview for DSM-IV Axis I Disorders, Investigator Version (SCID-I, modified) (SCID for DSM-IV) and ICD-10 diagnostic criteria. The presence and the severity of the disorders were assessed by means of the following intruments: Clinician-Administrated PTSD Scale for DSM-IV (CAPS-DX), Montgomery-Asberg Depression Rating Scale (MADRS) and 17-item Hamilton Rating Scale for Depression (HAMD). The differences between groups were evaluated using Student t test and by means of the correlational analysis of the data with p < 0.05. RESULTS: The obtained results showed that depression which was comorbid with PTSD was of significant clinical severity with 31.20 score on HAMD and 30.43 score on MADRS in PTSD-D group. The group of the symptoms: lassitude, inability to feel, suicidal thoughts and inner tension contributed mostly to the global severity of the comorbid clinical depression on MADRS. The group of the symptoms: suicide and somatic symptoms, gastrointestinal, guilt, hypochondriasis, work and activity, anxiety psychic, agitation, and weight loss, genital symptoms and anxiety somatic contributed mostly to the global severity of comorbid clinical depression on HAMD. The average score was 16.03 and 16.97 on HAMD and MADRS, respectively in PTSD group. CONCLUSION: Depression which is comorbid with posttraumatic stress disorder represents significant clinical entity with domination of the different groups of symptoms between the groups PTSD and PTSD-D on HAMD. Identification of aforementioned severity of illness and delineated group of symptoms lead the clinician to establish the diagnosis of depression, reduce the risk of diagnostic ommition of the depression and enable the clinician to chose the optimal treatment method for the delineated disorders.
