- 公共卫生 公共卫生
背景情况:
- 血清中25-氧维生素D (维生素D) 的水平已被调查,以确定与自闭症谱系障碍 (ASD) 的潜在关联.
- 了解因果关系对于潜在的治疗干预和公共卫生建议至关重要.
研究的目的:
- 使用双向门德尔随机化 (MR) 方法调查血清维生素D水平和自闭症谱系障碍 (ASD) 之间的因果关系.
- 为了确定维生素D缺乏是否是ASD的原因,或者ASD是否影响维生素D水平.
主要方法:
- 利用公开可用的全基因组关联研究 (GWAS) 数据集进行双向两样 MR 分析.
- 采用了各种MR方法,包括反变量加权 (IVW),加权中位数,MR-Egger回归,并使用贝叶斯加权MR (BWMR) 验证了发现.

Autism Spectrum Disorder
76
Autism spectrum disorder (ASD) is a neurodevelopmental condition marked by persistent deficits in social communication and interaction alongside restrictive and repetitive behaviors or interests. ASD is sometimes accompanied by intellectual impairment.
These core symptoms manifest differently among individuals, ranging from mild to severe. The disorder's complexity extends beyond its clinical presentation, encompassing a diverse range of biological, cognitive, and sociocultural influences.

Modeling in Therapy
59
Modeling, a key technique in therapy, uses observational learning to help clients acquire and practice new skills by watching therapists demonstrate desired behaviors. This approach, rooted in Albert Bandura's concept of vicarious learning, plays a significant role in therapeutic interventions for various psychological conditions, including social anxiety, ADHD, and depression.

Connective Tissue Cell Types
3.2K
Connective tissue develops from the mesoderm of a developing embryo and consists of cells, fibers, and ground substance: a gel-like material containing large complexes of carbohydrates and proteins. Connective tissue was first identified as a separate tissue family in the 18th century, and Johannes Peter Muller coined the term connective tissue.
Fat cells (adipocytes), smooth muscle cells (myoblasts), and bone cells (osteoblasts) are some connective tissue cell types. Some immune system cells...

Psychosis: Pathophysiology of Schizophrenia and Other Psychotic Disorders
514
Schizophrenia is a neurodevelopmental disorder whose origins are rooted in complex genetic components. Despite our burgeoning understanding, the pathophysiology of this disorder remains incompletely deciphered.
Researchers have identified genetic factors that increase susceptibility to schizophrenia, underscoring the intricate interplay between genetics and environment in disease development. At the core of schizophrenia's pathophysiology is excessive dopaminergic neurotransmission within...

Attention-Deficit/Hyperactivity Disorder
50
Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
Diagnostic Criteria and Symptoms
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings....

Biological Causes of Schizophrenia
51
Schizophrenia, a severe psychiatric disorder, arises from a complex interplay of biological factors, including genetic predisposition, structural brain abnormalities, neurotransmitter dysregulation, and developmental irregularities. These factors collectively contribute to the onset and progression of the disorder, which typically manifests in late adolescence or early adulthood.
Genetic Factors in Schizophrenia
The genetic basis of schizophrenia is strongly supported by family and twin...
