まとめ
栄養不良患者のグリリン濃度の高さは栄養不良の重さと相関しているが,入院中に栄養目標の達成を改善する. グレリンの類型は,脆弱な集団の栄養支援に役立ちます.
科学分野:
- 内分泌学
- 栄養学
- 臨床医学
背景:
- 酸素ホルモンであるグリリンは 視床下部経路を通して 食物摂取に影響します
- 病気に関連した栄養失調におけるグレリンの役割,そのレベル,病理生理学,および予後/治療の可能性に関するデータは限られている.
研究 の 目的:
- 栄養不良患者の入院時のグリリンレベルと栄養不良のフェノタイプ,栄養目標達成,治療応答の関連性を調査する.
- グレリンのレベルとの関係で30日間の全原因死亡率の主要な結果を分析する.
主な方法:
- 栄養不良の入院患者の脆弱性,機能的アウトカム,回復に対する早期栄養支援のランダム化制御試験 (EFFORT) の二次分析.
- 997人の患者で,グレリンの測定値が確認できた.
- 栄養不良の重症度 (栄養リスクスクリーニング,2002年 - NRS),栄養目標の達成,および死亡率との関連が評価された.
主要な成果:
- 高濃度のグレリンは,栄養失調の重症度 (NRS) と,栄養摂取量との逆相関に関連していた.
- グレリン濃度が高い患者は,栄養目標を達成する確率は1. 4倍 (調整されたOR1. 40) であった.
- 高いグリリン濃度と死亡率,合併症,または有害事象との関連は認められず,グリリン濃度が高いグループと低いグループの両方で栄養療法に対する反応は似ていた.
結論:
- 重度の栄養不良の患者で高濃度のグリリン摂取は,グリリン抵抗の可能性を示唆する.
- 潜在的耐性にもかかわらず,高レベルのグレリンは,入院中に栄養目標の達成と関連していました.
- グレリンの類型は栄養不良患者の栄養摂取を高め,グレリンの活動と抵抗メカニズムのさらなる研究を正当化します.

Regulation of Food Intake
370
Short-term regulation of food intake primarily involves neural signals from the gastrointestinal (GI) tract, blood nutrient levels, and GI tract hormones. Communication between the gut and brain via vagal nerve fibers plays a significant role in evaluating the contents of the gut. Clinical studies have shown that protein ingestion produces a more prolonged response in these nerve fibers compared to an equivalent amount of glucose. Additionally, the activation of stretch receptors caused by GI...

Hormonal Regulation

Hormones regulate a significant portion of digestion through activation of the neuroendocrine system. The neuroendocrine system of digestion contains many different hormones all with multiple functions that are both, directly and indirectly, involved in digestion.

Hypoglycemia and Glucagon
334
Without prolonged fasting, healthy individuals maintain blood glucose levels above 3.5 mM due to a well-adapted neuroendocrine counterregulatory system that effectively prevents acute hypoglycemia, a potentially life-threatening condition. The primary clinical scenarios for hypoglycemia encompass diabetes treatment, inappropriate production of endogenous insulin or insulin-like substances by tumors, and the use of glucose-lowering agents in non-diabetic individuals. Notably, hypoglycemia in the...

Enteral Nutrition II: Nasointestinal and Gastrostomy Feeding
284
Enteral nutrition encompasses various methods of delivering nutrition directly to the gastrointestinal (GI) tract, bypassing traditional oral intake. It is particularly beneficial for patients who cannot eat by mouth but have a functioning digestive system. Key methods include nasointestinal feeding, gastrostomy, and jejunostomy, each suited to different clinical scenarios based on the patient's needs and condition.

Glucagon-like Receptor Agonists

Incretins include glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP), which stimulate insulin secretion post-meals. In type 2 diabetes, GIP's efficacy is reduced, making GLP-1 a viable drug target. GIP originates from preproGIP.
GLP-1, when administered in high doses intravenously, triggers insulin secretion, inhibits glucagon release, slows gastric emptying, reduces food intake, and restores normal insulin secretion. However, its rapid inactivation by...

Chronic kidney disease (CKD) requires collaborative and comprehensive management. CKD progresses through stages and can lead to end-stage kidney disease (ESKD) if untreated. Interprofessional collaboration and patient education are crucial, enabling patients to manage their health and improve their quality of life.Diagnostic approach for chronic kidney diseaseThe diagnosis of CKD primarily focuses on the glomerular filtration rate (GFR), which assesses kidney function by measuring how well...
