Laser-induced breakdown spectroscopy (LIBS) is a promising technique for in situ elemental analysis. A new mobile instrument for LIBS analysis, developed in a collaboration between Marwan Technology s.r.l. and the Applied Laser Spectroscopy Laboratory in Pisa, is presented, and some applications of it and results from it are outlined. The innovative experimental set-up, based on the use of two suitably retarded laser pulses and a standardless analysis procedure, which overcomes problems related to matrix effects, greatly improves the potential of this technique for accurate quantitative analysis.

Objectives: We aimed to describe health-related quality of life (HRQoL), overall and across its dimensions, identify associated factors, and assess changes over time among people with HIV (PWH) from the Spanish multicentre CoRIS cohort.
Methods: We developed a mobile app to collect HRQoL data every 3 months using the WHOQOL-HIV-BREF questionnaire (31 items across six domains), among PWH followed in CoRIS in 2021-2023. Factors associated with good/very good global HRQoL and with domain-specific mean scores were identified using multivariable logistic and linear regression, respectively.

Background: In medial mobile-bearing unicompartmental knee arthroplasty (MB-UKA), the position of the bearing does not correspond to the planned position which will increasing the risk of bearing dislocation. This study aimed to explore the relationship between the malposition of the femoral and tibial components and the phenomenon of bearing deviation using postoperative radiological measurements.
Methods: One hundred twenty patients who underwent mobile-bearing uni-compartmental knee arthroplasty (MB-UKA) at our hospital between January and August 2023 were enrolled in this retrospective study.

Background: Dementia is a growing public health issue. Non-drug interventions targeting individuals before the onset of overt cognitive decline may be effective. Subjective cognitive decline (SCD) is present in > 50% of older adults and associated with progression to dementia.

Wearable systems for health monitoring are highly desired in personal diagnostics and precision medicine while challenges remain in constructing such wearable systems with reliability and high performance. Herein, we report a wearable platform for non-invasive monitoring biomarkers in sweat. The device is composed of a butterfly-shaped like microfluidic platform in which responsive photonic crystal hydrogels are embedded in each butterfly wing as sensors.

Background: As the common antibacterial drugs in folic acid oral liquid, parabens are listed as mandatory substances in the quality standard. Both the Chinese Pharmacopoeia and the United States Pharmacopoeia use high performance liquid chromatography for the determination of folic acid, but the quantitative methods of parabens are different. Pharmacopoeias use different instruments to quantify folic acid and parabens, resulting in cumbersome and cumbersome detection methods.
