[Biopsychosocial Factors Influencing Mortality and Functional Recovery in COVID-19 Patients Undergoing Prone Positioning: A Prospective Observational Study].

Unlabelled: Patients placed in a prone position due to COVID-19 present a more severe disease, longer stay in ICU and have more significant complications associated with positioning than other patients.

Aim: To identify social, health, and hospital factors associated with mortality and functional recovery in activities of daily living (ADL) in patients admitted to the ICU due to COVID-19 who were in the prone position.

Methods: We conducted a prospective observational study between June 2021 and March 2022 at the San José Clinical Hospital.

Fast treatment of anterior shoulder dislocations with two sedation-free methods: The Davos self-reduction method and Arlt method.

Background: Various reduction techniques exist to treat traumatic shoulder dislocation, but best management remains unclear.

Aims: To investigate the reduction rate of traumatic anteroinferior shoulder dislocations using two sedation-free techniques and success rates of subgroups.

Methods: A single-center study was performed analysing shoulder dislocations in a two-year period.

Controlled electron transfer by molecular wires embedded in ultrathin insulating membranes for driving redox catalysis.

Organic bilayers or amorphous silica films of a few nanometer thickness featuring embedded molecular wires offer opportunities for chemically separating while at the same time electronically connecting photo- or electrocatalytic components. Such ultrathin membranes enable the integration of components for which direct coupling is not sufficiently efficient or stable. Photoelectrocatalytic systems for the generation or utilization of renewable energy are among the most prominent ones for which ultrathin separation layers open up new approaches for component integration for improving efficiency.

Subsidence of Spinal Fusion Cages: A Systematic Review.

Background: Although many research studies investigating subsidence of intervertebral fusion cages have been published, to our knowledge, no study has comprehensively compared cage subsidence among all lumbar intervertebral fusion (LIF) techniques. This study aimed to review the literature reporting evidence of cage subsidence linked to LIF. The amount of subsidence was compared and associated with the procedures and corresponding implants used, and the effect of cage subsidence on clinical outcomes was investigated.

Time-Resolved Vibrational and Electronic Spectroscopy for Understanding How Charges Drive Metal Oxide Catalysts for Water Oxidation.

Temporally resolved spectroscopy is a powerful approach for gaining detailed mechanistic understanding of water oxidation at robust Earth-abundant metal oxide catalysts for guiding efficiency improvement of solar fuel conversion systems. Beyond detecting and structurally identifying surface intermediates by vibrational and accompanying optical spectroscopy, knowledge of how charges, sequentially delivered to the metal oxide surface, drive the four-electron water oxidation cycle is critical for enhancing catalytic efficiency. Key issues addressed in this Perspective are the experimental requirements for establishing the kinetic relevancy of observed surface species and the discovery of the rate-boosting role of encounters of two or more one-electron surface hole charges, often in the form of randomly hopping metal oxo or oxyl moieties, for accessing very low-barrier O-O bond-forming pathways.
