Objectives: To assess individually tailored ultrasound-assisted prompted voiding as a means of managing urinary incontinence in hospitalized elderly patients.
Methods: A total of 88 incontinent elderly individuals who were inpatients in general hospitals were included. Each individual's mean bladder volume before starting to void (voided urine volume plus residual urine volume) was regarded as the optimal bladder volume. Bladder volume was regularly monitored with an ultrasound device, and when the urine volume had reached the individual's optimal bladder volume, the subject was prompted to void. The outcomes were evaluated on the basis of scores on a four-grade scale for items in six domains: urine volume, voiding function, urinary control, physical and cognitive function for toileting, and caregivers' burden in regard to continence care. The score for use of a pad/diaper, an item of urinary control domain, was used as the primary outcome measure.
Results: A total of 80 participants were included for analysis. After ultrasound-assisted prompted voiding care for a 4-week period, the score for use of a pad/diaper in 50 out of 80 participants (62.5%) had decreased, and 21 out of 80 participants (26.3%) no longer required the use of a pad/diaper at all. The scores of the other 30 out of 80 participants (37.5%) were unchanged. The improvement was not significantly affected by patients' backgrounds at baseline. The mean scores in the domains of urinary control, physical function, cognitive function and caregivers' burden improved significantly.
Conclusion: The present preliminary study suggests that individually tailored ultrasound-assisted prompted voiding can improved urinary incontinence of institutionalized elderly patients. Further studies are worth carrying out.

Operated tendons are impacted by an inciting trauma and the subsequent treatment and will never again appear as they were prior to the insult. Post-operative tendons have unique ultrasound (US) findings that can be helpful to the surgeon in evaluating the success of repair, status of healing and confirmation that the repair remains intact. The advantage of US over physical exam or other imaging modalities is that it offers both static and dynamic assessment.

Article Synopsis
- Mango seeds, a byproduct of mango juice processing, are rich in starch, but traditional extraction methods are inefficient and environmentally harmful.* -
- The study improved starch extraction from mango seed cotyledons using ultrasound, achieving a maximum yield of 50.74%, which is 82.4% higher than conventional methods.* -
- The ultrasound method enhanced starch purity and properties while maintaining its structure, indicating potential uses in food and pharmaceuticals.*

The main waste generated by juice industry comprises orange peels, which have a great upcycling potential once stabilized. Drying is the most used method for this purpose, but the high energy consumption prompts interest in its intensification. This study assessed the influence of freeze-thaw and pulsed electric field (PEF) pretreatments in conventional and airborne ultrasound-assisted drying (50 °C) of orange peels.

Testicular torsion is a medical emergency that requires an immediate and multidisciplinary approach from emergency, surgical, and radiological services. In this article, we discuss the current knowledge and growing value of ultrasound (US) for intravaginal testicular torsion diagnosis and our experience with manual testicular detorsion with US assistance. Testicular torsion requires prompt and accurate diagnosis and quick therapeutic action.

Microalgal, species are recognized for their high protein content, positioning them as a promising source of this macronutrient. , in particular, is noteworthy for its rich protein levels (70 g/100 g dw), which are higher than those of meat and legumes. Incorporating this microalgae into food can provide various benefits to human health due to its diverse chemical composition, encompassing high amount of protein and elevated levels of minerals, phenolics, essential fatty acids, and pigments.
