概括

减肥手术后贫血很常见,影响近一半的患者. 终身监测和补充铁是至关重要的,特别是对于月经妇女来说,以防止Roux-en-Y胃绕道和袖子胃切除术后的缺陷.

科学领域:

腹部外科手术的结果
营养缺乏症营养缺乏症
胃肠病学胃肠病学

背景情况:

腹腔外科手术,包括Roux-en-Y胃绕道 (RYGB) 和袖子胃切除术 (SG),与贫血和微量营养素缺乏症的显著风险有关.
这些并发症可能会长期影响患者的健康和生活质量.

研究的目的:

为了确定RYGB后和SG后贫血的患病率.
为了确定在接受这些减肥手术的患者中与贫血相关的危险因素.

主要方法:

一项涉及100名在2016年至2022年期间接受RYGB或SG治疗的成年患者的横截面研究.
对人口统计数据,生化参数和多维生素 (MVT) 守的分析.
基于手术类型 (RYGB与SG) 的结果比较.

主要成果:

整体贫血患病率从手术前的14%增加到手术后的47%.
在RYGB (9.1%至47.7%) 和SG (17.9%至46.4%) 两组中,贫血率都很高.
手术后的缺陷包括铁 (44%),叶酸 (14%) 和维生素B12 (9%). 叶酸缺乏在SG后更高,而维生素B12缺乏是RYGB的特征. 经期女性患铁缺乏症的风险更高.

结论:

几乎一半的患者在减肥手术后患有贫血,月经妇女尤其容易受到伤害.
终身监测贫血和微量营养素缺乏是必不可少的.
应该考虑预防性补充铁来预防这些并发症.

关键词:

贫血贫血是因为贫血.胃切除术,袖子切除术微量营养素缺乏症是什么?在Roux-en-Y的胃旁路术中.

Prevalence and Incidence

Prevalence and Incidence

In statistical epidemiology and health sciences, two essential metrics—prevalence and incidence—are fundamental for understanding disease dynamics within a population. These measures enable public health officials, epidemiologists, and researchers to assess the burden of diseases, allocate resources effectively, and design impactful public health policies and interventions.
Prevalence indicates the proportion of individuals in a population who have a specific disease or health...

Key Elements for Plant Nutrition

Key Elements for Plant Nutrition

Like all living organisms, plants require organic and inorganic nutrients to survive, reproduce, grow and maintain homeostasis. To identify nutrients that are essential for plant functioning, researchers have leveraged a technique called hydroponics. In hydroponic culture systems, plants are grown—without soil—in water-based solutions containing nutrients. At least 17 nutrients have been identified as essential elements required by plants. Plants acquire these elements from the...

What is an Electrochemical Gradient?

What is an Electrochemical Gradient?

Adenosine triphosphate, or ATP, is considered the primary energy source in cells. However, energy can also be stored in the electrochemical gradient of an ion across the plasma membrane, which is determined by two factors: its chemical and electrical gradients.
The chemical gradient relies on differences in the abundance of a substance on the outside versus the inside of a cell and flows from areas of high to low ion concentration. In contrast, the electrical gradient revolves around an...

Measures of Central Tendency

Measures of Central Tendency

The "center" of a data set is also a way of describing location. The two most widely used measures of the "center" of the data are the mean (average) and the median. The words "mean" and "average" are often used interchangeably. The substitution of one word for the other is common practice. The technical term is "arithmetic mean" and "average" is technically a center location. However, in practice among non-statisticians,...
