主な方法:
- 41人の肥満児のアンソポメトリー,代謝マーカー (トリグリセリド,HDL-コレステロール,HOMA-IR) と血圧を評価した.
- 採取した糞便サンプルをベースラインと1年後に採取した.
- 関連性,回帰,ANCOM-BC2,LEfSe,ランダムフォレスト,およびROC分析を使用して,微生物群の特徴と介入の成功 (MetScoreまたはBMIのzスコア改善) を関連付けました.
主要な成果:
- ベースラインより高いシャノンとシンプソンの多様性指数と, *Faecalibacterium*と *Eubacterium coprostanoligenes*グループの豊富さは,より大きなメットスコア改善と相関しています.
- *Faecalibacterium*は最も高い予測重要性を示した (AUCはMetScoreで0.876,BMIのzスコアで0.873).
- 0.849のシンプソン指数カットオフで,MetScore,SBP,HDLコレステロールの有意な改善を示したハイダイバーシティの子供たちが特定されました.

Pharmacokinetics in Obese Patients: Drug Absorption and Distribution
310
Obesity significantly alters the pharmacokinetic processes of drug absorption and distribution, presenting unique challenges in medical treatment. The increased fat tissue and decreased lean muscle in obese individuals can significantly affect how drugs are absorbed into the body and distributed across different tissues. This alteration can lead to variances in the effectiveness and safety of medications, necessitating adjustments in dosing or drug selection for obese patients.One notable...

Anatomy of the Intestines

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...

Obesity
1.4K
The Body Mass Index (BMI) is a numerical value derived from a person's weight and height, used to categorize individuals into weight ranges. It is calculated using the formula: weight in kilograms divided by height in meters squared. Obesity is a health condition characterized by excessive accumulation of adipose tissue that poses health risks, often diagnosed with a BMI ≥ 30. This excess fat storage occurs when surplus dietary calories are converted into triglycerides and stored in...

Pharmacokinetics in Obese Patients: Drug Metabolism and Excretion
210
Drug metabolism, a critical process in the liver, involves two primary phases: Phase I reactions and Phase II conjugation. Obesity introduces significant alterations in this metabolic process, primarily due to fatty infiltration of the liver, leading to conditions such as nonalcoholic fatty liver disease (NAFLD). This condition can modify the activities of both Phase I and II enzymes, impacting how drugs are metabolized in obese patients.Phase I metabolism sees variable effects across...

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...

Drug Dosing: Obese Patients

In the United States, obesity is a prominent concern. It is linked to heightened mortality rates due to increased occurrences of conditions such as hypertension, atherosclerosis, coronary artery disease, and diabetes compared to nonobese individuals. A patient is classified as obese if their actual body weight surpasses the ideal or desirable body weight by 20%, based on Metropolitan Life Insurance Company data. Ideal body weights consider average weights and heights for males and females...
