- 传染性疾病 传染性疾病
背景情况:
- 自发早产 (sPTB),特别是极端的sPTB (<28周),经常是由胚胎内感染/炎症引起的.
- 胚胎内感染,包括Ureaplasma/Mycoplasma和细菌超级感染,与早产婴儿的严重长期认知障碍有关.
- 有效的产科策略对于预防sPTB和改善新生儿预后至关重要.
研究的目的:
- 开发和验证一种灵敏,准确的PCR方法来检测胚胎内感染.
- 根据感染/炎症状况,评估针对性抗生素治疗和17-alpha-hydroxyprogesterone caproate (17OHP-C) 在延长早产 (PTL) 病例中的妊娠效果.
- 强调需要准确的诊断信息来指导PTL的治疗决策.
主要方法:

- 在PTL患者中对抗生素治疗 (Ureaplasma/Mycoplasma的宏类药物,细菌的β-乳类药物) 的临床评估.
- 评估17OHP-C在PTL患者的疗效,这些患者有不同程度的胚胎内炎症.
主要成果:
- 通过PCR方法,可以准确地识别胚胎内感染,没有错误的阳性结果.
- 针对已确定的感染的抗生素治疗,在感染的PTL病例中,孕期延长了大约4周.
- 在没有胚胎内感染的情况下,抗生素的使用缩短了妊娠期.

44
Introduction:For diagnosing acute pyelonephritis, a comprehensive patient history is collected to identify symptoms such as dysuria, frequent or urgent urination, flank pain, or costovertebral angle (CVA) tenderness that may suggest a kidney infection.Physical ExaminationDuring the physical examination, CVA tenderness is assessed. This involves gentle percussion over the costovertebral angle, where tenderness often indicates a kidney infection.Diagnostic TestsUrinalysis: Used to identify white...

In managing urinary tract infections (UTIs) in nursing, a comprehensive assessment is essential. Begin by gathering subjective data, such as the patient’s complaints of dysuria (painful urination), urinary frequency, urgency, suprapubic pain, and any lower abdominal discomfort. This information can be complemented by questions regarding previous UTIs, sexual activity, and personal hygiene practices, which can provide insight into risk factors. Objective assessment should focus on signs...

A healthcare provider can diagnose a urinary tract infection (UTI) through several methods:Medical History and Symptoms: The provider will take a detailed medical history and ask about symptoms such as frequent urination, burning sensation during urination, and lower abdominal pain.Urinalysis: A clean-catch urine sample is collected in a sterile container and tested for the presence of bacteria, white blood cells (leukocytes), nitrites, blood, and protein. The presence of leukocytes and...

01:29Local Anesthetics: Clinical Application as Epidural Anesthesia
502
Epidural anesthetics are administered in the fat-filled epidural space, the outermost part of the spinal canal. This technique is commonly employed for pain management and anesthesia during lower abdomen and pelvis surgeries or labor and delivery.
Since epidural anesthetics can be infused through an epidural catheter, all types of drugs, including short-acting ones, can be administered. Chloroprocaine and lidocaine are examples of short and long-duration anesthetics, respectively. Bupivacaine...

The treatment of pneumonia varies based on its severity and the causative pathogen. Here is a structured approach to managing pneumonia, integrating pharmaceutical and supportive care strategies.
Bacterial Pneumonia Treatment
For bacterial pneumonia, antibiotics serve as the cornerstone of therapy. Initial treatment often begins with empirical antibiotics, tailored to the anticipated causative organism and adjusted based on culture results. Key antibiotic choices include:
