Traditional Chinese Medicine for Alzheimer's Disease: A Systematic Review and Meta-Analysis.

The treatment of Alzheimer's Disease (AD) remains a challenge for modern medicine due to its complex pathogenesis. Traditional Chinese Medicine (TCM) has demonstrated significant success in the prevention and treatment of variable medical conditions. For AD pharmacological management, TCM could provide promising approaches.

An intracranial yolk sac tumor with initial symptom of hemorrhage in the basal ganglia: a case report.

We report a case and follow-up of an adult male with intracranial yolk sac tumor (YST). Initially, the patient presented with abnormal high signals in the right basal ganglia on MRI, misdiagnosed as a cavernous hemangioma. However, within 2 years, the condition rapidly progressed into a large, hypervascular solid neoplasm leading to a basal ganglia hemorrhage.

Antipsychotic polypharmacy and high-dose antipsychotic therapy compared to antipsychotic monotherapy at standard doses in schizophrenia - a systematic review.

Background: Schizophrenia is considered to have a lifetime prevalence of around 1%. Up to 30% of patients diagnosed with schizophrenia are subsequently categorised as treatment resistant. Current guidelines advise against the use of antipsychotic polypharmacy (APP) or high-dose antipsychotic therapy (HDAT) in the treatment of schizophrenia; however, these treatment approaches continue to be used in up to 25% of cases.

Placebo effects in randomized trials of pharmacological and neurostimulation interventions for mental disorders: An umbrella review.

There is a growing literature exploring the placebo response within specific mental disorders, but no overarching quantitative synthesis of this research has analyzed evidence across mental disorders. We carried out an umbrella review of meta-analyses of randomized controlled trials (RCTs) of biological treatments (pharmacotherapy or neurostimulation) for mental disorders. We explored whether placebo effect size differs across distinct disorders, and the correlates of increased placebo effects.

Placebo effects in mental health disorders: protocol for an umbrella review.

Introduction: Given the high prevalence of mental health disorders and their significant socioeconomic burden, there is a need to develop improved treatments, and to evaluate them through placebo-controlled trials. However, the magnitude of the placebo response in randomised controlled trials to test medications may be substantial, affecting their interpretation. Therefore, improved understanding of the patient, trial and mental disorder factors that influence placebo responses would inform clinical trial design to better detect active treatment effects.

Effect of acceptance and commitment therapy for depressive disorders: a meta-analysis.

Objective: To systematically evaluate the effect of Acceptance and Commitment Therapy (ACT) on depressive disorders.

Methods: The electronic databases of Web of Science Core Collection, Pubmed, EMBASE, Cochrane Library, PsycInfo, CNKI, Wanfang and Weipu were used to select relevant publications. Screening, data extraction, and quality assessment were undertaken following PRISMA guidelines for preferred reporting of systematic reviews and meta-analysis.

An investigation of neuromelanin distribution in substantia nigra and locus coeruleus in patients with Parkinson's disease using neuromelanin-sensitive MRI.

Loss of neuromelanin in the midbrain is known in Parkinson's disease(PD), which can now be directly detected by neuromelanin-sensitive MRI(NM-MRI). This case-control study was to investigate the distribution of neuromelanin in the substantia nigra(SN) and the locus coeruleus(LC) using NM-MRI technique and evaluate its potential as a diagnostic marker for PD. 10 early PD patients(H&Y stage I, II), 11 progressive PD patients(H&Y stage III-V), and 10 healthy controls matched in age and gender were recruited.

Correlation analysis between D-dimer-to-fibrinogen-ratio and carotid plaque in young patients aged 18-45 with acute cerebral infarction.

Background: D-Dimer and fibrinogen were commonly used to detect the coagulation and fibrinolytic function, but D-dimer to fibrinogen ratio (DFR) in carotid plaque in young patients aged 18-45 with acute cerebral infarction (ACI) has not been used clinically. In this work, we focused on the evaluation of the DFR value of this group of patients and analyzed its possible correlation.

Methods: A total of 164 patients with ACI patients aged 18-45 were selected as research subjects after their first admission.

Locus coeruleus in the pathogenesis of Alzheimer's disease: A systematic review.

The locus coeruleus (LC) is a nucleus in the brain stem producing noradrenaline. While cognitive decline in Alzheimer's disease (AD) has primarily been related to cholinergic depletion, evidence indicates extensive LC degeneration as its earliest pathological marker. The current study aimed to systematically evaluate current evidence investigating the role of the LC in the pathogenesis of AD.

Immune-endocrine biomarkers associated with mental health: A 9-year longitudinal investigation from the Hertfordshire Ageing Study.

Background: The study of neural-endocrine-immune system interactions has led to substantial advances in our understanding of neuropsychiatric disorders. Growing evidence reveals the pivotal roles of inflammatory cytokines signalling the brain to produce neurochemical, neuroendocrine, and neuroimmune changes which affect mood and behaviour. Ageing is accompanied by the development of low-grade systemic inflammation which may promote changes in the neural systems predisposing to geriatric depression via the hypothalamic-pituitary-adrenal (HPA) axis.

Psychological distress after subarachnoid haemorrhage: A systematic review and meta-analysis.

Objective: Psychological distress is a common complication in patients after Subarachnoid haemorrhage (SAH) which often has significant impact on the prognosis. The objective of this study was to determine the pooled prevalence of anxiety symptoms and depressive symptoms in patients after SAH and identify relevant risk factors.

Methods: The study adopted a systematic review and meta-analysis protocol.

The Locus Coeruleus in Aging and Alzheimer's Disease: A Postmortem and Brain Imaging Review.

The locus coeruleus (LC), a tiny nucleus in the brainstem and the principal site of noradrenaline synthesis, has a major role in regulating autonomic function, arousal, attention, and neuroinflammation. LC dysfunction has been linked to a range of disorders; however particular interest is given to the role it plays in Alzheimer's disease (AD). The LC undergoes significant neuronal loss in AD, thought to occur early in the disease process.

A case-control study of the locus coeruleus degeneration in Alzheimer's disease.

The locus coeruleus (LC) is the major source of noradrenaline, which plays a key role in cognition. We aimed to detect the extent of the LC signal attenuation in Alzheimer's disease (AD) patients using a neuromelanin (NM)-sensitive MRI and how it may correlate with inflammatory and autonomic measures. An individually matched case-control study design was employed.

Anxiety in asthma: a systematic review and meta-analysis.

Background: Background: Growing evidence from observational studies indicates a high prevalence of anxiety in asthma. However, prevalence rates of coexisting anxiety symptoms and comorbid anxiety disorders vary widely across studies. We aimed to evaluate the associations between anxiety and asthma and provide more precise comorbidity estimates.

Caring for patients in mental health services during COVID-19 outbreak in China.

This article reflects on some radical changes made in mental health services in China which include the implementation of the initial triage system and the special isolation ward, the early screening and testing for both patients and staff, the smaller teams working on rotating shifts on-site, and the adequate provision of PPE. These measures would be of great value as a reference to the effective delivery of mental health services in other countries through this pandemic.

Effects of SSRIs on peripheral inflammatory cytokines in patients with Generalized Anxiety Disorder.

Background: Extensive research into psychoneuroimmunology has led to substantial advances in our understanding of the reciprocal interactions between the central nervous system and the immune system in neuropsychiatric disorders. To date, inflammation has been implicated in the pathogenesis of depression and anxiety. The immunomodulating effects of antidepressants on depression have been reported, however, there is no evidence of the similar effects of antidepressants on anxiety.

Effects of SSRIs on peripheral inflammatory markers in patients with major depressive disorder: A systematic review and meta-analysis.

Introduction: Peripheral levels of inflammatory markers are elevated in major depressive disorder (MDD). Selective serotonin reuptake inhibitors (SSRIs) affect levels of inflammatory markers in patients with MDD, but studies have reported inconsistent findings. This systematic review and meta-analysis aims to investigate the effects of SSRI treatment on peripheral levels of a range of inflammatory markers in MDD patients.

Peripheral proinflammatory cytokines in Chinese patients with generalised anxiety disorder.

Background: Inflammatory responses and inflammatory cytokines have been implicated in the pathogenesis of affective disorders, particularly major depression. Given the limited evidence relating to the potential role of proinflammatory cytokines in generalised anxiety disorder (GAD), we aimed to examine peripheral proinflammatory cytokines in Chinese patients with GAD.

Methods: A case-controlled cross-sectional study design, with recruitment of 48 patients with first episode GAD and 48 matched healthy controls.

Pharmacotherapy in Generalized Anxiety Disorder: Novel Experimental Medicine Models and Emerging Drug Targets.

Many pharmacological and psychological approaches have been found efficacious in patients with generalized anxiety disorder (GAD), but many treatment-seeking patients will not respond and others will relapse despite continuing with interventions that initially had beneficial effects. Other patients will respond but then stop treatment early because of untoward effects such as sexual dysfunction, drowsiness, and weight gain. There is much scope for the development of novel approaches that could have greater overall effectiveness or acceptability than currently available interventions or that have particular effectiveness in specific clinical subgroups.

Peripheral inflammatory cytokines and immune balance in Generalised Anxiety Disorder: Case-controlled study.

Introduction: Previous investigations have demonstrated that major depression is associated with particular patterns of cytokine signalling. The primary aim of this study was to examine peripheral pro-inflammatory and anti-inflammatory cytokines and immune balance in Generalised Anxiety Disorder (GAD).

Methods: A case-controlled cross-sectional study design was employed: 54 patients with GAD and 64 healthy controls were recruited.
