概括
在腹部外科手术后使用暴露前预防 (PrEP) 的男性中,丁二酸盐 (TFV-DP) 水平仍然具有治疗效果. 这项研究评估了使用TDF/FTC或TAF/FTC的个体的TFV-DP度,遵循RYGB或SG程序.
科学领域:
- 药理动力学和药物新陈代谢
- 胃肠道手术 胃肠道手术
- 预防传染病 预防传染病
背景情况:
- 减肥手术可以改变药物的吸收和新陈代谢.
- 了解特诺福维二酸盐 (TFV-DP) 水平对于在腹腔外科手术后的患者暴露前预防 (PrEP) 疗效至关重要.
- 有限的数据存在TFV-DP度的个体经历了减肥手术.
研究的目的:
- 测量二酸 (TFV-DP) 度在干血斑点 (DBS) 中,来自在减肥手术前或之后接受暴露前预防 (PrEP) 的人.
- 为了评估使用二二二醇烟酸加恩特里奇他 (TDF/FTC) 或二阿拉芬胺加恩特里奇他 (TAF/FTC) 治疗方案的患者的TFV-DP水平.
- 为了将TFV-DP度与减肥手术类型和PrEP疗程相关联.
主要方法:
- 从正在接受或曾经接受减肥手术 (Roux-en-Y胃绕道手术[RYGB]或袖子胃切除手术[SG]) 的暴露前预防 (PrEP) 用户收集了干血斑点 (DBS) 样本.
- 使用液态染色体协同质谱法 (LC-MS/MS) 量化了TFV-DP度.
- 结果与人群范围进行比较,并按手术时间表,手术类型和PrEP方案 (TDF/FTC或TAF/FTC) 分层.
主要成果:
- 其中包括7名同性恋, cis-性别男性 (平均年龄48岁);6人先前接受过减肥手术 (四名RYGB,两名SG).
- 所有参与者,除了一个在SG之后的TDF/FTC,都表现出治疗TFV-DP度.
- 在RYGB之前,TAF/FTC的一个参与者显示TFV-DP略有下降,但水平仍然是治疗性的.
结论:
- 在口服预暴露预防 (PrEP) 中,二酸 (TFV-DP) 度在这种小队列的男性腹腔外科手术后 (RYGB或SG) 中通常具有治疗效果.
- 这些发现表明,减肥手术可能不会显著损害大多数人PrEP有效性所需的TFV-DP水平.
- 需要对更大的样本进行进一步的研究来证实这些观察.

Pulmonary Tuberculosis I
220
Tuberculosis, often called TB, is a contagious illness primarily caused by Mycobacterium tuberculosis. It mainly affects the lung parenchyma but can also impact other body parts.
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.

Retrovirus Life Cycles
45.6K
Retroviruses have a single-stranded RNA genome that undergoes a special form of replication. Once the retrovirus has entered the host cell, an enzyme called reverse transcriptase synthesizes double-stranded DNA from the retroviral RNA genome. This DNA copy of the genome is then integrated into the host’s genome inside the nucleus via an enzyme called integrase. Consequently, the retroviral genome is transcribed into RNA whenever the host’s genome is transcribed, allowing the...
