Clinical characteristics of lactational breast abscess caused by methicillin-resistant Staphylococcus aureus: hospital-based study in China.

Background: This study aimed to identify the differences in clinical characteristics, puncture efficacy, antibiotic use, treatment duration, breastfeeding post-illness, and recurrence of patients with breast abscesses caused by methicillin-resistant Staphylococcus aureus (MRSA) or methicillin-susceptible Staphylococcus aureus (MSSA) infection during lactation.

Methods: The clinical data of patients with breast abscesses during lactation who were treated from January 2014 to February 2017 at Haidian Maternal and Child Health Hospital, Beijing, were reviewed. According to bacterial culture results, they were divided into MRSA (n = 260) and MSSA (n = 962) groups.

Risk Factors for Failure of Ultrasound-Guided Fine-Needle Aspiration Therapy for Lactational Breast Abscess.

Ultrasound-guided fine-needle aspiration in the treatment of breast abscess has become the preferred treatment. Although fine-needle aspiration has a good therapeutic effect, there are still some patients failed who finally underwent drainage. To analyze the risk factors of ultrasound-guided fine-needle aspiration treatment failure for patients with lactational breast abscess.

Machine Learning Models to Improve the Differentiation Between Benign and Malignant Breast Lesions on Ultrasound: A Multicenter External Validation Study.

Purpose: This study aimed to establish and evaluate the usefulness of a simple, practical, and easy-to-promote machine learning model based on ultrasound imaging features for diagnosing breast cancer (BC).

Materials And Methods: Logistic regression, random forest, extra trees, support vector, multilayer perceptron, and XG Boost models were developed. The modeling data set of 1345 cases was from a tertiary class A hospital in China.

Lactational Breast Abscesses Caused by Methicillin-Resistant or Methicillin-Sensitive Infection and Therapeutic Effect of Ultrasound-Guided Aspiration.

We investigated whether (1) there are any differences in lactational breast abscesses between patients from whom methicillin-resistant (MRSA) and those from whom methicillin-sensitive (MSSA) were isolated from pus samples and (2) there are differences in the effects of ultrasound-guided aspiration. The clinical data of 171 patients with lactational breast abscesses treated by ultrasound-guided aspiration in Beijing from January to July 2018 were retrospectively analyzed. The patients were divided into MSSA infection ( = 132) and MRSA infection ( = 39) groups according to their bacterial culture results.
