AI Article Synopsis
- Soft-tissue vibrations can help measure properties of human tissue and how it reacts to impact, with this study focusing on running.
- The research compared high-speed motion capture and accelerometry for measuring vibration amplitude and frequency, finding similar measurement errors for both techniques.
- It concluded that while both methods yielded comparable results, the video method struggled with capturing high-frequency data, indicating a tradeoff between accuracy and frequency in measuring soft tissue vibrations during running.
Article Abstract
Soft-tissue vibrations can be used to quantify selected properties of human tissue and their response to impact. Vibrations are typically quantified using high-speed motion capture or accelerometry. The aim of this study was to compare the amplitude and frequency of soft-tissue vibrations during running when quantified by highspeed motion capture and accelerometry simultaneously. This study showed: (a) The estimated measurement errors for amplitude and frequency were of the same order of magnitude for both techniques. (b) There were no significant differences in the mean peak frequencies and peak amplitudes measured by the two methods. (c) The video method showed an inability to capture high frequency information. This study has shown that a tradeoff has to be made between the accuracy in amplitude and frequency when these methods are employed to quantify soft tissue vibrations in running.

Background: Despite the wide use of compression garments to enhance athletic running performance, evidence supporting improvements has not been conclusive. This updated systematic review and meta-analysis of randomized controlled trials (RCTs) compared the effects of compression garment wearing with those of non-compression garment wearing (controls) during running on improving running performance.
Methods: A comprehensive search was conducted in the electronic databases (Web of Science, EBSCOhost, PubMed, Embase, Scopus, and Cochrane) for RCTs comparing running performance between runners wearing compression garments and controls during running, from inception to September 2024.

: The aim of this systematic review was to evaluate the clinical efficacy, benefits, and limitations of piezosurgery in tooth extractions compared to conventional methods. Piezosurgery has emerged as a minimally invasive alternative, promoting better preservation of soft tissues and bone structures. Understanding its impact on postoperative outcomes such as pain, swelling, trismus, and bone healing is critical for its application in oral surgery; We restricted our search to English-language articles published between 1 January 2004 and 28 August 2024, in PubMed, Scopus, and Web of Science.

Soft tissue vibrations (STV) can generate discomfort during running. Recent research has shown that footwear affects the amplitude of STV differently across runners but no studies have linked human characteristics and footwear construction yet. The purpose of this study was to investigate the runner specific STV responses to various midsole hardness and to identify functional groups, that is, groups of runners responding similarly to a given intervention.

Article Synopsis
- Occupational exposure to vibration from hand-held tools can lead to hand-arm vibration syndrome (HAVS), as shown in the case of a 39-year-old dental technician who experienced chronic wrist pain, numbness, and tingling for three years after five years of repetitive tool use.
- She was diagnosed with bilateral median nerve neuropathy, mild carpal tunnel syndrome, and had MRI results indicating soft tissue damage due to repetitive strain injury, particularly in her dominant right wrist.
- A workplace health risk assessment identified high-risk tasks associated with her symptoms, leading to modifications and monitoring protocols that helped stabilize her condition.

Article Synopsis
- Primary atopic disorders (PAD) are rare genetic conditions caused by specific gene variants that affect skin and immune function, making diagnosis challenging among common allergic disease cases.
- Identifying PAD requires recognizing clinical red flags like family history and unusual infections, as conventional lab tests are inadequate for definitive diagnosis.
- Whole-genome sequencing (WGS) enhances diagnostic efficiency and accuracy, but requires careful interpretation and collaboration among specialists to effectively manage PAD cases.
