背景:
- 自閉症スペクトル障害 (ASD) の病因は完全に理解されていません.
- ASDの子供には 胃腸の問題があり 選択的な食生活があり 独特の腸内微生物群があります
- 腸の健康はASDの発症と症状に 影響を及ぼします
研究 の 目的:
- ASDと神経型対照群の腸内微生物の組成を比較する.
- ASDの子供の食事と食事の違いを調査する.
- 腸内微生物群と 食生活とASDの関係を探るため
主な方法:
- 10人のASDの男性と10人の男性神経型対照の糞便サンプルによる16S rRNAのシーケンシング
- 人口統計,食事習慣,胃腸症状,便の特徴に関するアンケート
- 簡潔な自閉症の食事時の行動インベントリー (BAMBI) スケールと48時間の食事リコール.
主要な成果:
- 腸内微生物群のベータ多様性における有意な差異が観察されました.
- バクテロイド菌はコントロール群で支配的であったが,フィルミキュート菌,アクティノバクテロイド菌,プロテオバクテリアはASD群で支配的であった.
- 特定のバクテリアの属は異なっており,ASDグループは食事に関連する行動問題を多く示しました.
結論:
- ASDの子どもは 腸内微生物群の特徴と 食事の習慣が異なっています
- 発見はASDの管理における胃腸および栄養学的要因の重要性を強調しています.
- 原因と治療の可能性を理解するためにさらなる研究が必要である.

Autism Spectrum Disorder
335
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.

Anatomy of the Intestines
73.8K
Although digestion of proteins, carbohydrates, and lipids may begin in the stomach, it is completed in the intestine. The absorption of nutrients, water, and electrolytes from food and drink also occurs in the intestine. The intestines can be divided into two structurally distinct organs—the small and large intestines.
Small Intestines
The small intestine is an ~7 meter-long tube with an inner diameter of just 2.5 cm. Since most nutrients are absorbed here, the inner lining of the...

Modeling in Therapy
145
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.

Irritable Bowel Syndrome I: Introduction
369
Irritable Bowel Syndrome (IBS) is characterized by functional disturbances in the gastrointestinal system, presenting a cluster of symptoms without evident structural or biochemical abnormalities. It primarily affects the large intestine and may cause abdominal pain, bloating, excessive gas, diarrhea, constipation, or both.
IBS is a chronic condition that can persist over a long period or recur frequently.
The pathogenesis of IBS involves a complex interplay of the following factors:

Inflammatory Bowel Disease III: Diagnostic Studies and Management I-Nutritional Therapy
413
Various diagnostic tests are employed in the diagnostic process for Inflammatory Bowel Disease (IBD), particularly to differentiate between Crohn's disease and ulcerative colitis.
Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...
