Background: The high prevalence of desynchronized biological rhythms is becoming a primary public health concern. We assess complex and diverse inter-modulations among multi-frequency rhythms present in blood pressure (BP) and heart rate (HR).
Subjects: and Methods: We performed 7-day/24-hour Ambulatory BP Monitoring in 220 (133 women) residents (23 to 74 years) of a rural Japanese town in Kochi Prefecture under everyday life conditions.
Article Synopsis
- Postprostatectomy incontinence is a common issue after prostate surgery, and this study investigates how pelvic floor muscle movements impact recovery of bladder control using cine MRI technology.
- The study involved 128 prostate cancer patients undergoing robotic surgery, comparing preoperative and postoperative bladder elevation distances to explore their relationship with recovery outcomes.
- Results showed that a longer preoperative bladder elevation distance (greater than 8.5 mm) was linked to faster recovery of continence, suggesting that this measurement could help in evaluating risks and guiding rehabilitation efforts post-surgery.
Objective: To evaluate the usefulness of quantitative diffusion-weighted (DW) imaging acquired by multivendor magnetic resonance units for predicting grade of hepatocellular carcinoma (HCC).
Methods: 83 patients with 100 histologically diagnosed HCCs who underwent pre-operative liver DW imaging with b = 0 and1000 s mm or b = 0 and800 s mm at any of six institutions were included. Two radiologists independently measured the apparent diffusion coefficient (ADC) of the lesion as well as non-ADC parameters, such as the relative contrast ratio and the contrast-to-noise ratio (CNR) between the lesion and the liver parenchyma on high b-value DW images.
Purpose: Because superparamagnetic iron oxide is actively taken into the reticuloendothelial system, the signal intensity observed on T2-weighted images is reduced not only in the liver but also in the spleen. There is no difference in the reduction in signal intensity in the liver after contrast between the ferumoxides and ferucarbotran, but the reduction in signal intensity in the spleen is considerable. In the present study, we examined the efficacy of T2*-weighted imaging to compensate for the reduction in signal intensity in the spleen by administering ferucarbotran.

Materials And Methods: A total of 945 patients undergoing enhanced CT were randomly assigned to receive one of two doses of contrast medium. We then prospectively investigated the incidence of adverse reactions.
