In recent years, escitalopram (ESC) has been suggested to have different mechanisms of action beyond its well known selective serotonin reuptake inhibition. The aim of this study is to investigate the effects of escitalopram on oxidative stress, apoptosis, brain-derived neurotrophic factor (BDNF), Methyl-CpG-binding protein 2 (MeCP2), and oligodendrocytes number in the brain of chronic unpredictable mild stress-induced depressed rats. The animals were randomised in four groups (8 in each group): control, stress, stress + ESC 5 and stress + ESC 5/10. ESC was administered for 42 days in a fixed dose (5 mg/kg b.w.) or in an up-titration regimen (21 days ESC 5 mg/kg b.w. then 21 days ESC 10 mg/kg b.w.). Sucrose preference test (SPT) and elevated plus maze (EPM) were also performed. ESC improved the percentage of sucrose preference, locomotion and anxiety. ESC5/10 reduced the oxidative damage in the hippocampus and improved the antioxidant defence in the hippocampus and frontal lobe. ESC5/10 lowered caspase 3 activity in the hippocampus. Escitalopram had a modulatory effect on BDNF and the number of oligodendrocytes in the hippocampus and frontal lobe and also improved the MeCP2 expressions. The results confirm the multiple pathways implicated in the pathogenesis of depression and suggest that escitalopram exerts an antidepressant effect via different intricate mechanisms.

(1) Background: Recent research suggests inflammation as a factor involved in the pathophysiology of mood disorders. Neutrophil-to-lymphocyte (NLR), monocyte-to-lymphocyte (MLR), platelet-to-lymphocyte (PLR), and systemic immune-inflammatory (SII) index ratios have been studied as peripheral markers of inflammation in bipolar and major depressive disorders. The purpose of this study is to comparatively analyze these inflammatory ratios among manic episodes of bipolar disorder, bipolar depression and unipolar depression. (2) Methods: 182 patients were retrospectively included in the study and divided into three groups: 65 manic patients, 34 patients with bipolar depression, and 83 unipolar depressive patients. White blood cells, neutrophils, monocytes, lymphocytes, and platelets were retrieved from the patients’ database. NLR, MLR, PLR, and SII index were calculated using these parameters. (3) Results: Patients with manic episodes had elevated NLR (p < 0.001), MLR (p < 0.01), PLR (p < 0.05), and SII index (p < 0.001) compared to unipolar depression and increased NLR (p < 0.05) and SII index (p < 0.05) when compared to bipolar depression. NLR (p < 0.01) and SII index (p < 0.05) were higher in the bipolar depression than unipolar depression. NLR is an independent predictor of the bipolar type of depression in depressive patients. (4) Conclusions: The results confirm the role of inflammation in the pathophysiology of mood disorders and suggest the ability of NLR as a marker for the differentiation of bipolar from unipolar depression.

Through the years, the available psychopharmacological treatments have expanded with numerous new drugs. Besides weight gain, gastro-intestinal problems or Parkinson-like symptoms, ocular adverse effects of psychiatric drugs have been reported. These adverse effects are not common, but can be dangerous for the patient. This review summarises the current knowledge on the risk of raised intraocular pressure and glaucoma entailed by psychopharmacological treatment. Also, it provides updated data for clinicians involved in the treatment of patients with glaucoma or glaucoma risk factors. For this purpose, we performed an extensive literature search in the PubMed database using specific terms. Selective serotonin and noradrenaline reuptake inhibitors are the best evidenced as having no association with glaucoma. Antipsychotics, and especially first generation, seem to have no correlation with an increased intraocular pressure and therefore possibly with a risk of glaucoma, although a special attention should be paid when using ziprasidone. Tricyclic antidepressants, benzodiazepines and topiramate should be avoided in patients diagnosed with glaucoma or at risk. Clinicians should be aware of the possible psychotropic drug induced glaucoma and monitor at risk patients closely in order to prevent this condition. Irrespective of the psychopharmacological regimen taken into consideration, the glaucoma patient should be under the strict supervision of the ophthalmologist.

Background: Schizophrenia is a chronic and severe mental illness that ultimately leads to reduced quality of life (QoL). Over the years, QoL has emerged as an important outcome in the treatment of schizophrenia patients, but the role of psychosocial variables in determining QoL is still ambiguous. Therefore, in the present research, demographic, clinical and psychosocial variables were examined for their influence on QoL. Methods: We conducted a prospective and cross-sectional study on a sample of 139 patients with schizophrenia (72.7% females, age 48.17 ± 10.22) attending an outpatient service. QoL was measured using Schizophrenia Quality of Life Revision-4 (SQLR4) and internalised stigma, self-esteem, perceived social support, resilience and coping mechanisms were assessed using a battery of standardized self-report scales. Results: Female patients and those less adherent to treatment had reduced cognition and vitality QoL. The worst QoL in all domains was observed in patients with a younger age at illness onset and with six or more hospitalizations. Regression analysis indicated that reduced self-esteem, perceived social support, a larger number of hospitalization and increased internalised stigma predicted poorer overall QoL and accounted for 44.9% in the variance in SQLSR4 global score (adjusted R2 = 0.449, p = 0.046). Conclusions: Routine assessment of internalised stigma, self-esteem and perceived social support, in addition to demographic and clinical variables and addressing possible deficits in these areas through personalized intervention, could improve QoL in schizophrenia patients.

The COVID-19 pandemic resulted in a global sanitary crisis and, in addition, elicited serious mental health consequences. The utilization of psychiatric hospital-based services acts as an indicator of public mental health. Therefore, this research sought to investigate differences in the numbers and characteristics of inpatient admissions for psychotic and affective disorders at the largest Romanian psychiatric hospital between the period of lockdown (16 March–15 May 2020) and another three corresponding periods: the same year in the pre-lockdown period (16 January–15 March 2020), the immediate post-lockdown period (16 May–15 July 2020), and two years later (16 March–15 May 2022). A retrospective analysis was performed. The study included a total of 6604 patients. Inpatient admissions decreased during lockdown in comparison with the pre-lockdown period and immediate post-lockdown period for psychotic disorders (p < 0.001 and p < 0.001, respectively) and affective disorders (p < 0.001 and p < 0.001, respectively). For both psychotic and affective disorders, a decrease in the age of the patients admitted during lockdown, as compared with the pre-lockdown period (p < 0.05 and p < 0.001, respectively), was observed. The length of the hospital stay for affective disorders was higher immediately post-lockdown in comparison with the lockdown period (p < 0.001). Collectively, the present findings provide a glimpse of the immediate and long-term consequences of the COVID-19 pandemic and lockdown measures on patients’ access to mental healthcare in the form of hospitalization, and these findings could provide the basis for the development of a different approach to times of crisis.
