Background: Restricted motion during touch screen device use may contribute to wrist overuse injuries. Wrist radioulnar deviation and extension while using touch screen devices and digital or manual counterparts in male and female medical professional dominant and non-dominant hands were quantified to test the hypothesis that mobile touch screen device use reduces wrist motion.

Methods: An active motion detection system was used to record wrist motion of 12 participants while: tablet swiping and turning book pages; raising a cell and traditional phone to the ear; texting and typing; and entering numbers on a cell phone and manual calculator. Medial and lateral wrist surface range of motion (ROM) and minimum and maximum wrist radial-ulnar deviation and flexion-extension were quantified.

Results: Device, sex and handedness effects were determined (P<0.05). Maximum medial radial deviation and ROM were greater using a cell versus traditional phone. Maximum medial radial deviation was higher in the nondominant wrist during backward tablet swiping and while backward page turning versus tablet swiping. Maximum and minimum medial extension angles and ROM were greater while typing versus texting. Female nondominant hand maximum lateral extension and ROM were greater for typing versus texting and maximum medial extension and lateral extension ROM greater during manual versus cell phone calculator use with handedness combined. Maximum lateral extension and ROM were greater in females versus males using manual calculators.

Conclusions: Sex and handedness should instruct touch screen, digital and manual device design and use for optimal performance and injury prevention.

Patients with Mild Cognitive Impairment (MCI) may exhibit poorer performance in visuomotor tasks than healthy individuals, particularly under conditions with high cognitive load. Few studies have examined reaching movements in MCI and did so without assessing susceptibility to distractor interference. This proof-of-concept study analyzed the kinematics of visually guided reaching movements towards a target dot placed along the participants' midsagittal/reaching axis.

Stylus pen-based ambient ionization mass spectrometry for the analysis of volatiles and semivolatiles from liquid, viscous, and solid samples.

Background: Ambient ionization mass spectrometry (MS) has attracted significant attention due to its simplicity and ease of operation. Contactless, or field-induced, ionization is one of the ambient ionization techniques. In this approach, no direct electrical contact or additional voltage is required on the ionization-assisted substrate.

Background: The efficacy of immune checkpoint inhibitors (ICIs) depends on the tumor immune microenvironment (TIME), with a preference for a T cell-inflamed TIME. However, challenges in tissue-based assessments via biopsies have triggered the exploration of non-invasive alternatives, such as radiomics, to comprehensively evaluate TIME across diverse cancers. To address these challenges, we develop an ICI response signature by integrating radiomics with T cell-inflamed gene-expression profiles.

An individual shows handedness when they consistently prefer one hand over the other for tasks that can be performed with either hand. Humans have a population-level right-hand preference, and past research shows that a variety of nonhuman primate species also show hand preferences. More complex manual tasks elicit stronger hand preferences than less complex manual tasks, but not much is known about hand preferences during a cognitive task in nonhuman primates.

Detection of sensory deficits in fine nerve fibres in leprosy diagnosis.

Objectives: The purpose of this study was to determine reference points for thermal perception in cutaneous lesions of leprosy, a disease caused by Mycobacterium leprae characterised by hypoesthesia in skin lesions due to nerve and Schwann cell infection. Early diagnosis is essential to control transmission and effectively treat the disease.

Methods: Quantitative thermal testing (QTT) has been proposed as a valuable tool for early detection of the disease, initiation of treatment, and monitoring of nerve damage.
