概括
患者经常报告代谢手术后的味道变化,但这项研究发现味道强度没有差异. 然而,在手术后的组中,嗅觉发生了改变,这表明味道可能受到影响,而不是味道.
科学领域:
- 感官科学 感官科学
- 腹部外科手术的结果
- 胃肠病学 胃肠病学
背景情况:
- 患者经常报告在代谢手术后改变了味觉感知.
- 之前使用经过验证的方法进行的研究没有发现味道强度的客观变化.
- 自我报告的味道变化可能涉及与气味/味道的混,或是条件依赖 (食与禁食).
研究的目的:
- 调查代谢手术后自我报告的味道变化是由于改变了味道,气味 (味道),还是取决于条件.
- 为了比较女性在代谢手术后的感官感知 (味觉,嗅觉,味觉) 与具有同等和健康体重指数 (BMI) 的非手术对照.
- 为了确定感官知觉是否在禁食和食状态之间有所不同.
主要方法:
- 横截面研究比较了三组女性:代谢手术后 (n=15),未经手术的BMI等效对照 (n=15) 和健康的BMI对照 (n=15).
- 每位参与者有两次会议:一个是禁食,一个是食.
- 感官评估使用吸入和吐液体样本 (味觉和嗅觉刺激) 和含脂肪布丁,有或没有鼻子剪贴,通过通用标签大小尺度评估味道,气味,风味和喜欢强度.
主要成果:
- 后代谢手术和BMI等效组报告了与健康的BMI组相比,咖啡的鼻后嗅觉强度更强.
- 两组之间在口味强度,风味强度或喜欢评分方面没有发现显著差异.
- 食条件 (禁食与食) 并没有显著影响感知强度等级.
结论:
- 在代谢手术后,客观的味道强度和风味感知似乎没有显著改变.
- 手术后和BMI等级组中嗅觉增加表明味道感知的潜在变化,而不是味道本身.
- 感官歧视性味道变化或味道-气味相互作用不太可能是代谢手术后饮食修改的主要驱动因素.

Taste Buds and Receptors
1.9K
Gustation, or the sense of taste, is intrinsically linked to the anatomical structures located on the tongue. This organ's surface, along with the entirety of the oral cavity, is adorned with stratified squamous epithelium. Evident on the tongue are elevated structures known as papillae (singular = papilla), which house the mechanisms for the transduction of gustatory stimuli. Four distinct types of papillae exist, each identified by their unique morphological attributes: the circumvallate,...

The Physiology of Taste
3.8K
The perception of a salty flavor is facilitated by sodium ions within the oral salivary fluid. Upon consumption of a salty substance, salt crystals disassemble, leading to the liberation of its constituents—Na+ and Cl- ions. These ions subsequently dissolve into the salivary fluid present in the oral cavity. The external environment of the gustatory cells experiences an elevation in Na+ concentration, thereby establishing a potent concentration gradient. This gradient propels the...

Gustation
47.7K
Gustation is a chemical sense that, along with olfaction (smell), contributes to our perception of taste. It starts with the activation of receptors by chemical compounds (tastants) dissolved in the saliva. The saliva and filiform papillae on the tongue distribute the tastants and increase their exposure to the taste receptors.

Enteral Nutrition I: Orogastric and Nasogastric Feeding
215
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.
Orogastric (OG) and nasogastric (NG) feeding are two standard methods used for enteral nutrition. Enteral nutrition is often preferred over...

Enteral Nutrition II: Nasointestinal and Gastrostomy Feeding
85
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.

Salivary Glands and Saliva
513
The salivary glands, of which there are three pairs known as the parotid, submandibular, and sublingual glands, play a crucial role in maintaining oral health and initiating the digestive process. Positioned near the ears, beneath the masseter muscle, the parotid glands secrete saliva into the oral cavity through the parotid duct of Stensen. Meanwhile, the submandibular glands, located on the floor of the mouth, secrete saliva through channels named submandibular ducts. The sublingual glands,...
