The incursion of coronavirus disease 2019 (COVID-19) reached global scale in 2020, requiring a response from leaders worldwide. Although the virus is a ubiquitous problem, world leaders have varied appreciably in their responses resulting in substantially different outcomes in terms of virus mitigation, population health, and economic stability. One explanation for this inconsistency is that leaders have taken differential approaches to making sense of the crisis that, in turn, have driven their approaches to decision making and communication. The present article elaborates on the role of leaders as sensemakers and explains how a leader's sensemaking approach is a critical element in successful crisis management efforts. Through the charismatic, ideological, pragmatic (CIP) leadership model, a sensemaking-focused theory of leadership, it is explained how specific, relatively stable sensemaking approaches manifest and what actions leaders engaged in those styles are likely to take in times of crisis. These connections are then reinforced through case examples of 3 world leaders, framed through CIP, and demonstrate how their sensemaking approach has influenced their response to COVID-19. The article concludes with a discussion of the impacts that these differential approaches to COVID-19 may have on the global community, and recommendations for more explicit incorporation of sensemaking into our understanding of leadership.

The use of dual-tracer contrast agents in clinical applications, such as sentinel lymph node (SLN) identification, offers significant advantages including enhanced accuracy, sensitivity, as well as comprehensive and multimodal visualization. In the current clinical practice, SLNs are typically marked prior to surgical resection by multiple and sequential injections of two tracers, the radioactive tracer and methylene blue (MB) dye. This imposes physical and psychological burden on patients and medical staff.

Background: The objective of this study was to determine the conditioning factors for scientific research productivity in university students of health sciences.Scientific productivity, in addition to making visible the generation of new knowledge, contributes to the well-being of the population and provides feedback to the scientific community in terms of methodologies, perspectives and results that help to break down barriers that delimit productivity in scientific research.
Methods: A cross-sectional analytical observational study was conducted.

Objectives: Hypoglossal nerve stimulation (HGNS) is a promising surgical option for patients with obstructive sleep apnea (OSA) who are intolerant of continuous positive airway pressure therapy (CPAP). Efficacy studies for HGNS stimulation largely focus on the apnea-hypopnea index and/or oxygen desaturation index. This study's objective was to show the physiological effects of HGNS stimulation on upper airway patency, airflow, and treatment effect during polysomnography (PSG) testing.

Optically-pumped magnetometer (OPM) has been of increasing interest for biomagnetic measurements due to its low cost and portability compared with superconducting quantum interference devices (SQUID). Miniaturized spin-exchange-relaxation-free (SERF) OPMs typically have limited bandwidth (less than a few hundred Hertz), making it difficult to measure high-frequency biomagnetic signals such as the magnetocardiography (MCG) signal of the mouse. Existing experiments mainly use SQUID systems to measure the signal.

A fair comparison of multiple live cell cultures requires examining them under identical environmental conditions, which can only be done accurately if all cells are prepared simultaneously and studied at the same time and place. This contribution introduces a multiplexed lensless digital holographic microscopy system (MLS), enabling synchronous, label-free, quantitative observation of multiple live cell cultures with single-cell precision. The innovation of this setup lies in its ability to robustly compare the behaviour, i.
