The collective experience of moral distress: a qualitative analysis of perspectives of frontline health workers during COVID-19.
Philos Ethics Humanit Med
January 2025
Department of Allergy, Immunology and Respiratory Medicine, Central Clinical School, The Alfred Hospital, Monash University, Melbourne, Australia.
Background: Moral distress is reported to be a critical force contributing to intensifying rates of anxiety, depression and burnout experienced by healthcare workers. In this paper, we examine the moral dilemmas and ensuing distress personally and collectively experienced by healthcare workers while caring for patients during the pandemic.
Methods: Data are drawn from free-text responses from a cross-sectional national online survey of Australian healthcare workers about the patient care challenges they faced.
Frequency locked whispering evanescent resonator (FLOWER) for biochemical sensing applications.

Sensitive, rapid and label-free biochemical sensors are needed for many applications. In this protocol, we describe biochemical detection using FLOWER (frequency locked optical whispering evanescent resonator)-a technique that we have used to detect single protein molecules in aqueous solution as well as exosomes, ribosomes and low part-per-trillion concentrations of volatile organic compounds. Whispering gallery mode microtoroid resonators confine light for extended time periods (hundreds of nanoseconds).

Wearable and implantable biosensors have rapidly entered the fields of health and biomedicine to diagnose diseases and physiological monitoring. The use of wired medical devices causes surgical complications, which can occur when wires break, become infected, generate electrical noise, and are incompatible with implantable applications. In contrast, wireless power transfer is ideal for biosensing applications since it does not necessitate direct connections between measurement tools and sensing systems, enabling remote use of the biosensors.

Electronic address:
Background: Scanning electrochemical microscopy (SECM) is a kind of scanning probe technology that enables the obtainment of surface morphology and electrochemical information by recording changes in Faraday current triggered by the movement of probe.
Results: In this work, flexible disk ultramicroelectrode (UME) with highly repeatable geometry are fabricated through a simple and universal strategy that involves vacuum pulling the glass capillaries inserted with platinum wire (gold wire, carbon fiber, etc.), followed by a rapidly heated sealing and polishing process.
Development and evaluation of a polymer material-based formulation for non-surgical nasolabial fold reduction.
Int J Cosmet Sci

Makeup Products Research, Kao Corporation, Odawara, Japan.
Objective: Currently, nasolabial folds are mainly removed by invasive procedures, resulting in long-lasting changes, as non-surgical user-implementable alternatives are scarce and inefficient. For example, the use of coating films for this purpose has thus far faced substantial difficulties because such films should combine the antithetical properties of shrinkability and flexibility. Herein, we challenge this status quo by identifying a polymer that simultaneously exhibits shrinkability and flexibility and using this polymer to develop a cosmetic formulation for immediate and non-invasive nasolabial fold removal.
