Association of Anaesthetists guidelines: the use of blood components and their alternatives 2024.

Background: The administration of blood components and their alternatives can be lifesaving. Anaemia, bleeding and transfusion are all associated with poor peri-operative outcomes. Considerable changes in the approaches to optimal use of blood components and their alternatives, driven by the findings of large randomised controlled trials and improved haemovigilance, have become apparent over the past decade.

Predictive relationship between COVID-19 anxiety and psychological distress in adolescents during the COVID-19 pandemic.

COVID-19 was a novel stressor that gave rise to pandemic related anxiety and increased the risk of mental health issues, particularly in youth. It is important to understand how such events contribute to psychological distress in young people to adequately intervene in the aftermath and to plan for future similar events. Using cross-sectional data from the CoSPACE Ireland study dataset this paper reports on the predictive relationship between COVID-19 anxiety and psychological distress for Irish adolescents ( = 314,  = 14.

Facile interconversion of mesitylcopper into a CuMes-Cubis(amidinate) triangle and a tetracuprous Möbius strip.

A new flexible bis(amidine) ligand featuring two additional N-donor groups incorporates a defined [CuMesCu] fragment from mesitylcopper into a triangular cluster with a reactive organometallic coordination site. Subtle changes to the reaction protocol result in the formation of an intertwined tetracuprous arrangement that adopts the shape of a Möbius strip.

HEMANGIOSARCOMA IN RED WOLVES () AND GRAY WOLVES () IN HUMAN CARE: SIX CASES.

Wolves are commonly housed in zoological institutions and captive breeding facilities that are essential for maintaining genetic diversity and for the recovery of declining populations. Neoplasia is a common cause of mortality in wolves, but hemangiosarcoma has not previously been described. This condition was diagnosed in four red wolves () and two gray wolves () housed at five different institutions between 2008 and 2018.

Assessment of Exercise Capacity in Home Healthcare: Differences in Three Self-Paced Tests.

Submaximal functional tests of endurance are ubiquitous in clinical practice. This investigation compared cardiovascular responses, perceived exertion, and performance measures following the completion of three self-paced, 2-minute, functional tests of endurance. A pilot prospective, observational, cross-sectional design with 16 community-dwelling older participants compared heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP), rating of perceived exertion (RPE), and performance measures following the completion of three randomly allocated self-paced activities.
