概括
更坚固的乳房植入物可以减少并发症,但会增加翻转风险,特别是在更高的BMI和体积不匹配的情况下. 手术规划是最小化这种风险的关键.
科学领域:
- 整形外科 整形外科 整形外科
- 重建性手术是一种重建性手术.
- 生物材料是一种生物材料.
背景情况:
- 外科医生越来越多地喜欢更坚固的凝植入物,以获得稳定性和减少并发症.
- 这一趋势与180度前后植入物翻转的增加有关.
- 识别导致植入物翻转的因素对于患者安全至关重要.
研究的目的:
- 为了确定与180°前后植入物翻转相关的患者和植入因子.
- 分析植入物特性与扩展器到植入物交换中的翻转之间的关系.
主要方法:
- 一项为期5年的回顾性队列研究,涉及343名患者 (502个乳房) 接受扩展器到植入器交换.
- 计算和分析扩展器填充体积,植入体积和三角形到扩展器的百分比.
- 多变量后勤回归以确定植入物翻转的独立预测因子.
主要成果:
- 植入物翻转发生在4.2%的乳房中.
- 相关因素包括更高的BMI,更大的扩展器填充量,以及使用高度坚固的植入物.
- 独立预测因素是BMI,高度坚固的植入物,以及最高的三角形-扩展三角形.
结论:

Stages of Infection
65.3K
Stages of infection describe what happens to a susceptible host once a pathogen invades the human body. The stages of infection are incubation, prodromal, illness, stage of decline, and convalescence. The incubation stage is the period from exposure to a pathogen until symptoms start. The infected person is unaware of impending illness as the pathogens grow and multiply within the body. The duration may vary depending on the type of infection. The incubation period of measles averages ten to...

Stages of General Anesthesia
1.7K
Various sedation levels offer significant advantages in facilitating procedural interventions for patients undergoing medical or invasive surgical procedures. These levels span from anxiolysis to general anesthesia, providing a spectrum of sedative effects to cater to specific patient needs. Anxiolysis reduces anxiety and is achieved through minimal sedation, enabling patients to remain awake and responsive while feeling more at ease during the procedure. This level can benefit minor...

Stages of Sleep
1.5K
Sleep progresses through distinct stages, each characterized by specific brain wave patterns and physiological responses ranging from wakefulness to stages of non-rapid eye movement, known as non-REM, to rapid eye movement, referred to as REM. Understanding these stages helps in recognizing how sleep supports various bodily and cognitive functions.
Before sleep begins, in wakefulness, the brain exhibits primarily beta waves, which are high in frequency and low in amplitude, indicating alertness...

Reconstruction of Signal using Interpolation
735
Signal processing techniques are essential for accurately converting continuous signals to digital formats and vice versa. When a continuous signal is sampled with a period T, the resulting sampled signal exhibits replicas of the original spectrum in the frequency domain, spaced at intervals equal to the sampling frequency. To handle this sampled signal, a zero-order hold method can be applied, which creates a piecewise constant signal by retaining each sample's value until the next...

Psychosexual Stages of Personality: Oral
3.2K
The oral stage is the initial phase of Sigmund Freud's theory of psychosexual development, occurring from birth to approximately 12 to 18 months. During this period, the infant's mouth serves as the primary source of pleasure, with actions such as sucking, chewing, biting, and drinking playing a crucial role in reducing tension. These activities are essential not only for nourishment but also for the infant's psychological and emotional satisfaction.

Psychosexual Stages of Personality: Anal
4.1K
Sigmund Freud's theory of psychosexual development describes the anal stage as occurring between 18 months and three years of age. During this period, children derive pleasure from controlling and releasing their bowel movements. However, they quickly learn that societal expectations impose restrictions on when and where this can happen. This stage marks a critical point where children begin to develop a sense of control and mastery over their bodily functions, as well as their broader...
