概括
与胃绕道手术后的蛋白质粉末补充剂 (PPS) 相比,蛋白质液体补充剂 (PLS) 改善了粘附性和减少了营养不足. 此外,PLS还增加了基底代谢率,表明整体恢复更好.
科学领域:
- 减肥手术的结果
- 营养科学
- 代谢健康
背景情况:
- 代谢和减肥手术 (MBS) 具有显著的健康益处,但由于饮食变化而带来营养并发症的风险.
- 评估蛋白质补充策略对于MBS患者的康复和长期健康至关重要.
- 这项研究将蛋白质液体补充剂 (PLS) 与常规蛋白质粉末补充剂 (PPS) 对Roux-en-Y胃旁路 (GBP) 患者进行了比较.
研究的目的:
- 为了比较PLS和PPS组之间的蛋白质补充的坚持率.
- 评估PLS与PPS对每日蛋白质摄入量和GBP后营养状况的影响.
- 评估两组补充剂之间身体组成和代谢率的差异.
主要方法:
- 一项为期2个月的随机对照试验,涉及50名经过Roux-en-Y胃绕道 (GBP) 的患者.
- 患者被分配给蛋白质液体补充剂 (PLS) 或常规蛋白质粉末补充剂 (PPS).
- 评估身体组成,休息的能量消耗,营养状况,蛋白质摄入量和坚持.
主要成果:
- 在PLS和PPS组中,体重减轻和无脂肪质量变化相似.
- 在手术后2个月,PLS组的基础代谢率显著提高.
- 与PPS组 (42. 0%) 相比,PLS组的坚持率明显高.
- 与PPS相比,PLS显著降低了25OH-维生素D缺乏率 (28.6%与90%) 和异常的转移素和率 (8.3%与57.1%).
结论:
- 蛋白质液体补充剂 (PLS) 显示出较高的坚持性,并且可能是符合GBP后蛋白质建议的更有效的策略.
- 比蛋白粉补充剂 (PPS) 更有效地帮助减轻营养不足,如维生素D缺乏和贫血.
- 经过胃绕道手术后的基础代谢率增加表明,PLS似乎支持代谢恢复.

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.

Enteral Nutrition I: Orogastric and Nasogastric Feeding
463
Enteral nutrition delivers nutrients directly to the stomach or small intestine through a tube. This method is appropriate for patients who cannot eat but still have a functioning digestive system. It is also beneficial for individuals with swallowing difficulties, anorexia, malabsorption, or those who have undergone gastrointestinal (GI) surgery.

Overview of Protein Metabolism
1.8K
Proteins are broken down into amino acids during digestion. Unlike fats and carbohydrates, which are stored for later use, proteins are not. Instead, amino acids are either used to produce ATP through oxidation or contribute to the creation of new proteins for the growth and repair of the body. Any surplus amino acids from the diet are converted into glucose or triglycerides rather than excreted.
Amino acids play various roles in the body once they are absorbed into cells. They are restructured...

Chronic Kidney Disease III: Interprofessional Care
78
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...

Proteins: Dietary Sources and Requirements
622
Consuming animal-based products offers high-quality proteins that contain optimal levels and combinations of essential amino acids, crucial for tissue repair and growth. Foods like eggs, milk, fish, and most meats are a source of complete proteins. Legumes and cereals are abundant in proteins; however, they typically lack a full range of essential amino acids. As a result, they are considered incomplete protein sources. Some plant sources like soybeans, quinoa, and amaranth do contain complete...

Insulin: Dosing Regimen and Adverse Effects
257
Insulin-replacement therapy usually includes both long-acting insulin (basal) and short-acting insulin (to cater to postprandial needs). In a diverse group of type 1 diabetes patients, the average daily insulin dose is typically 0.5-0.7 units/kg body weight. However, obese patients and pubertal adolescents may need more due to insulin resistance.
The basal dose constitutes about 40%-50% of the total daily dose, with the rest as premeal insulin. The mealtime insulin dose should mirror...
