概括
女早产婴儿吃奶粉,蛋白质和卡路里比男性更多,当他们被自由养时. 这项研究突出了晚期早产婴儿的性别特定营养需求,挑战了统一的养假设.
科学领域:
- 新生儿科学 新生儿科学
- 儿童营养学 儿童营养学
- 婴儿的成长 婴儿的成长
背景情况:
- 过早出生的婴儿通常需要通过鼻胃管处方的食量,卡路里和蛋白质,因为口服难以获得.
- 现有的假设表明,早产婴儿一旦开始自由养,即使他们在身体组成中存在已知的基于性别的差异,仍然需要统一的营养需求.
研究的目的:
- 调查晚期早产婴儿随意养的配方奶粉摄入量 (体积和营养素) 的潜在性别差异.
- 挑战在早产婴儿养中统一营养要求的假设.
主要方法:
- 在34 0/7和36 6/7周之间对170名晚期早产婴儿 (85名男性,85名女性) 进行了回顾性分析,纠正了妊娠期.
- 纳入标准:适合妊娠年龄,自发养的ad-lib配方,没有呼吸支≥2天.
- 排除标准:短肠综合征,严重的染色体异常,先天性心脏病. 收集的数据:性别,妊娠年龄,出生体重,人体测量,母亲数据,营养摄入量,新生儿发病率.
主要成果:
- 女性婴儿与男性婴儿相比 (135.3 ± 19.3 mL/kg/d; p=0.002) 消耗了显著更多的配方体积 (145.5 ± 20.8 mL/kg/d).
- 女婴的蛋白质和卡路里摄入量也更高.
- 性别之间没有观察到ad-lib养时间的显著差异,但女性婴儿的生长速度更快.
结论:
- 这项研究是首次报告晚期早产婴儿在食用配方奶粉中的性别差异.
- 研究结果表明,在这个人群中,营养需求可能因性别而异.
- 需要进一步的研究来证实这些结果,并探索极度早产婴儿的性别特异性新生儿营养.

Anatomy of the Intestines
71.9K
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...

Signs of Puberty
337
Puberty is a critical phase, typically beginning between the ages of 8 and 13 in girls and 9 and 14 in boys, though timing can vary based on genetics, environmental factors, and overall health. This period is characterized by the development of secondary sexual characteristics and the attainment of reproductive potential. Endocrine changes underpin puberty, with hormonal surges of Luteinizing Hormone (LH) and Follicle-Stimulating Hormone (FSH) instigated by Gonadotropin-Releasing Hormone (GnRH)...

Inflammatory Bowel Disease III: Diagnostic Studies and Management I-Nutritional Therapy
331
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...
