Objective: To evaluate the impact of a single-shot preoperative antimicrobial prophylaxis (AMP) to reduce the rate of Surgical Site Infections (SSIs) in a rural sub-Saharan hospital.
Summary Background Data: We analyzed the incidence of SSIs in a rural Tanzanian hospital with very limited resources and found that AMP was administered after incision in 88% without covering the expected pathogens. Inadequacy and mistiming of AMP proved to be major risk factors for SSI in this study. Subsequently, 21.6% of patients developed an SSI after clean or clean-contaminated surgery, with 60% of detected pathogens being resistant to the administered antibiotics. In developed countries, preoperative single shot AMP is widely used and effective in the prevention of SSI.
Methods: Implementation and monitoring of guidelines for routine and adequate single shot AMP within 2 hours prior to incision in every clean and clean-contaminated intervention.
Results: In the preintervention group, 527 patients qualified for routine AMP that was administered in 88% of patients after incision and did not cover the expected pathogens to a large extent.114 patients (21.6%) developed an SSI, with 60% of detected pathogens being resistant to the administered antibiotics. After implementation of the guidelines, the incidence of SSIs significantly decreased from 21.6% to 4% (11/276).
Conclusions: The implementation of a single shot AMP dramatically decreased the rate of SSI in a hospital with very limited resources. Such guidelines, developed by industrialized countries, are even more effective in non-industrialized countries.

Medical image annotation is scarce and costly. Few-shot segmentation has been widely used in medical image from only a few annotated examples. However, its research on lesion segmentation for lung diseases is still limited, especially for pulmonary aspergillosis.

Atrial fibrillation (AF) is the most common cardiac arrhythmia and pulmonary vein isolation (PVI) by percutaneous transcatheter ablation is its pivotal treatment. Nowadays, several techniques using different energy sources are used, such as radiofrequency (RF), cryoablation and laser ablation. A new technology that combines the strengths of different techniques has been developed, in particular having both the speed of one-shot techniques and the selectivity and precision of point-by-point RF: the RF balloon (RFB).

: Accurate and reproducible spleen volume measurements are essential for assessing treatment response and disease progression in myelofibrosis. This study evaluates techniques for measuring spleen volume on abdominal MRI. : In 20 patients with bone marrow biopsy-proven myelofibrosis, 5 observers independently measured spleen volume on 3 abdominal MRI pulse sequences, 3D-spoiled gradient echo T1, axial single-shot fast spin echo (SSFSE) T2, and coronal SSFSE T2, using ellipsoidal approximation, manual contouring, and 3D nnU-Net model-assisted contouring comparing coefficients of variation.

Breath-hold T2-weighted half-Fourier acquisition single-shot turbo spin echo (HASTE) magnetic resonance imaging (MRI) of the upper abdomen with a slice thickness below 5 mm suffers from high image noise and blurring. The purpose of this prospective study was to improve image quality and accelerate imaging acquisition by using single-breath-hold T2-weighted HASTE with deep learning (DL) reconstruction (DL-HASTE) with a 3 mm slice thickness. MRI of the upper abdomen with DL-HASTE was performed in 35 participants (5 healthy volunteers and 30 patients) at 3 Tesla.

Purpose: To compare the quality of DWI images, signal loss of left hepatic lobe and diagnostic performance of apparent diffusion coefficient (ADC) values between SS-EPI and iShim-EPI in liver lesions.
Methods: Totally 142 patients were involved, images using SS-EPI and the prototype iShim-EPI were acquired before injection of gadoxetic acid-enhanced liver MRI.Image quality of demarcation of liver capsule, resolution, lesion distortion, artifacts, lesion confidence score, and signal loss in left hepatic lobe was assessed by two radiologists.
