BACKGROUND: The clinical debut of schizophrenia is frequently a first episode of psychosis (FEP). As such, there is considerable interest in identifying associations between biological markers and clinical or cognitive characteristics that help predict the progression and outcome of FEP patients. Previous studies showed that high prolactin, low oxytocin and high homocysteine are factors associated with FEP 6 months after diagnosis, at which point plasma levels were correlated with some clinical and cognitive characteristics...

BACKGROUND: Although depression has been a serious neuropsychiatric disorder worldwide, current antidepressants used in clinical practice have various weaknesses including delayed onset and low rates of efficacy. Recently, the development of new antidepressants from natural herbal medicine has become one of the important research hotspots. Cucurbitacin B is a natural compound widely distributed in the Cucurbitaceae and Cruciferae families and has many pharmacological activities. The present study aimed to investigate whether cucurbitacin B possess antidepressant-like effects in mice...

BACKGROUND: Previous studies have focused on both ventral striatum (VS) and dorsal striatum (DS) in characterizing dopaminergic deficits in addiction. Animal studies suggest VS and DS dysfunction each in association with impulsive and compulsive cocaine use during early and later stages of addiction. However, few human studies have aimed to distinguish the roles of VS and DS dysfunction in cocaine misuse. METHODS: We examined VS and DS resting-state functional connectivity (rsFC) of 122 recently abstinent cocaine-dependent individuals (CDs) and 122 healthy controls (HCs) in 2 separate cohorts...

BACKGROUND: Racemic ketamine consists of two enantiomers, namely (R)ketamine and (S)ketamine, with distinguishable pharmacological properties. Both enantiomers have been reported to show rapid antidepressant effects in rodents. Currently, the (S)enantiomer has been approved for the treatment of major depression, while (R)ketamine failed to show antidepressant effect in recent clinical studies. Major depressive disorder is frequently characterized by disinhibition of rapid eye movement (REM) sleep and disruption of nonREM (NREM) sleep...

BACKGROUND: We recently showed sex differences in the antidepressant-like potential of electroconvulsive seizures (ECS) in adolescent rats; while it worked for male rats it rendered inefficacious in females. Since sex steroids might be important modulators of these sex disparities, we evaluated the role of estrogens in the differential response induced by adolescent ECS. Moreover, given the literature suggesting certain cognitive sequelae from ECS exposure, we aimed at evaluating its long-term safety profile in adulthood...

BACKGROUND: A prominent finding in Major Depressive Disorder (MDD) is distorted stress hormone dynamics, which is regulated by serotonergic brain signaling. An interesting feature of the cerebral serotonin system is the serotonin 4 receptor (5-HT4R), which is lower in depressed relative to healthy individuals, and also has been highlighted as a promising novel antidepressant target. Here, we test the novel hypothesis that brain 5-HT4R availability in untreated patients with MDD is correlated with cortisol dynamics, indexed by the cortisol awakening response (CAR)...

BACKGROUND: Increased levels of occupational stress among health professionals during the COVID-19 pandemic have been documented. Few studies examined the effects of the pandemic on mental health professionals despite the heightened demand for their services. METHOD: A multilingual, longitudinal, global survey was conducted at three time points during the pandemic among members of the WHO's Global Clinical Practice Network (GCPN). 786 GCPN members from 86 countries responded to surveys assessing occupational distress, well-being and post-traumatic stress symptoms...

BACKGROUND: Wendan decoction (WDD) has been used as a treatment for depression in China since the Tang Dynasty. However, high-quality evidence for this is lacking. This study proposed a novel synthetic external control method to evaluate its clinical efficacy. METHODS: Clinical trials of WDD for major depression were searched for using public databases. The rate of change of the Hamilton Depression Scale (HAMD) score from baseline was used as an efficacy indicator, and a model-based meta-analysis (MBMA) was performed to analyze the clinical efficacy of WDD...

BACKGROUND: The role of neurofilament light chain (NFL) in treatment-resistant depression (TRD) is unclear. Whether baseline NFL concentrations are associated with the antidepressant effects of low-dose ketamine infusion has not been determined. METHODS: The NFL concentrations of 71 patients with TRD and 17 healthy controls were assessed. Patients with TRD were randomly administered a single infusion of 0.5 mg/kg ketamine, 0.2 mg/kg ketamine, or normal saline...

BACKGROUND: Alzheimer's disease (AD) and depression often co-occur, and inhibition of phosphodiesterase-4 (PDE4) has been shown to ameliorate neurodegenerative illness. Therefore, we explored whether PDE4 inhibitor rolipram might also improve the symptoms of comorbid AD and depression. METHODS: APP/PS1/tau mice (10 months old) were treated with or without daily intraperitoneal injections of rolipram for 10 days. The animal groups were compared in behavioral tests related to learning, memory, anxiety, and depression...

BACKGROUND: Post-traumatic stress disorder is characterized by deficits in cognitive flexibility related to dysfunction of the medial prefrontal cortex (mPFC). Exposure therapy can effectively reverse these deficits. Fear extinction in rodents bears similarity to exposure therapy. Extinction reverses chronic stress-induced deficits in cognitive flexibility on the attentional set-shifting test (AST), a mPFC-mediated process. This therapeutic effect requires activity of pyramidal neurons and BDNF signaling in infralimbic cortex (IL)...

BACKGROUND: Paliperidone palmitate 6-month (PP6M) demonstrated noninferiority to paliperidone palmitate 3-month (PP3M) in preventing relapse in patients with schizophrenia in a phase-3 double-blind (DB) study (NCT03345342). Here, we report long-term efficacy and safety results from a 2-year single-arm, open-label extension (OLE; NCT04072575) of this DB study. METHODS: Participants who completed the DB study without relapse were enrolled and followed-up every 3 months up to 2 years...

BACKGROUND: Impaired antioxidant defense is implicated in the pathophysiology of schizophrenia; and superoxide dismutase (SOD), catalase (CAT), and glutathione (GSH) are three first-line endogenous antioxidants. Various cognitive functions decline differently during schizophrenia course. The characteristic roles of the three antioxidants in clinical and cognitive profiles in acute and chronic phases of schizophrenia require study. METHODS: We recruited 311 patients with schizophrenia, including 92 acutely exacerbated patients who had been off antipsychotics for at least 2 weeks and 219 chronic patients who had been stable on medication for at least 2 months...

BACKGROUND: Diminished heart rate variability (HRV) has been observed in epilepsy, especially in epilepsy with depressive disorders. However, the underlying mechanism remains elusive. METHODS: We studied HRV, spontaneous recurrent seizures (SRSs) and depression-like behaviors in different phases of pilocarpine-induced temporal lobe epilepsy (TLE) in mice. Single-cell RNA sequencing analysis was used to identify various nerve cell subsets in TLE mice with and without depression...

BACKGROUND: Clinician adherence to guideline recommendations in the pharmacological therapy of schizophrenia is important for favorable patient outcomes. To evaluate whether prescriptions followed the guidelines for pharmacological therapy of schizophrenia, we recently developed a summary indicator of multiple quality indicators: the individual fitness score (IFS). It is unclear whether adherence to the guidelines is related to patient outcomes. Here, we investigated correlations between the IFS values and psychotic symptoms in patients with schizophrenia...
