The aim of this study was to stratify 305 elderly (> 65 years) treated at an academic health center (Botucatu, São Paulo, Brazil) according to risk of repeated hospitalization. Data collection used an instrument to evaluate risk of repeated hospital admissions, including eight health indicators: self-rated health, hospitalizations, doctor visits, diabetes, cardiovascular disease, gender, social support, and age. 56.4% of interviewees presented low probability of repeated hospitalization, as compared to 26.9% medium, 10.5% medium-high, and 6.2% high probability. Combining health indicators with the probability of repeated hospitalization, for elderly classified as medium, medium-high, and high risk compared to low, the relative risk was significant: medium or bad health (2.31); hospitalization (2.38); > 3 doctor visits (1.75); diabetes (2.10); cardiovascular disease (2.76); male gender (1.68); and > 75 years of age (1.62). The instrument was able to stratify elderly at risk of repeated hospitalization and is thus useful for reorganizing public health services.

Breast density assessment via quantitative sound-speed measurement using conventional ultrasound transducers.

Department of Information Technology, Uppsala University, 75237, Uppsala, Sweden.
Objectives: The aim is to assess the feasibility and accuracy of a novel quantitative ultrasound (US) method based on global speed-of-sound (g-SoS) measurement using conventional US machines, for breast density assessment in comparison to mammographic ACR (m-ACR) categories.
Materials And Methods: In a prospective study, g-SoS was assessed in the upper-outer breast quadrant of 100 women, with 92 of them also having m-ACR assessed by two radiologists across the entire breast. For g-SoS, ultrasonic waves were transmitted from varying transducer locations and the image misalignments between these were then related analytically to breast SoS.
Automatic 4D mitral valve segmentation from transesophageal echocardiography: a semi-supervised learning approach.

Performing automatic and standardized 4D TEE segmentation and mitral valve analysis is challenging due to the limitations of echocardiography and the scarcity of manually annotated 4D images. This work proposes a semi-supervised training strategy using pseudo labelling for MV segmentation in 4D TEE; it employs a Teacher-Student framework to ensure reliable pseudo-label generation. 120 4D TEE recordings from 60 candidates for MV repair are used.

Cerebral palsy is a complex lifespan disability caused by a lesion to the immature brain. Evaluation of interventions for children with cerebral palsy requires valid and reliable outcome measures. Motor development curves and reference percentiles for The Gross Motor Function Measure (GMFM-66) are valuable tools for following, predicting, comparing, and evaluating changes in gross motor skills.

To review the outcomes of patients who underwent repeated vertebroplasty (VP) surgery for adjacent segment fractures (ASF), defined as new osteoporotic vertebral fractures occurring at levels immediately above or below a previously treated vertebra. From 1 January 2018, to 31 December 2020, forty-one patients who developed ASF following initial VP and underwent repeated VP were enrolled in our study. Radiographic measurements included single and two-segment kyphotic angles (SKA and TKA), and anterior and mid-vertebral body height (AVH and MVH).

The effectiveness of bariatric surgery in reducing remnant cholesterol (RC) levels, particularly when obesity is accompanied by elevated glycated hemoglobin (HbA1c), is insufficiently investigated. In this study, we aimed to examine the impacts of two common bariatric procedures, Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG), as regards their effects on RC and HbA1c levels. Adult morbidly obese subjects were included and assigned to receive either RYGB or SG.
