Effect of Tiered Implementation of Clinical Decision Support System for Acute Kidney Injury and Nephrotoxin Exposure in Cardiac Surgery Patients.

Background:  Nephrotoxin exposure may worsen kidney injury and impair kidney recovery if continued in patients with acute kidney injury (AKI).

Objectives:  This study aimed to determine if tiered implementation of a clinical decision support system (CDSS) would reduce nephrotoxin use in cardiac surgery patients with AKI.

Methods:  We assessed patients admitted to the cardiac surgery intensive care unit at a tertiary care center from January 2020 to December 2021, and August 2022 to September 2023.

MMORF-FSL's MultiMOdal Registration Framework.

We present MMORF-FSL's MultiMOdal Registration Framework-a newly released nonlinear image registration tool designed primarily for application to magnetic resonance imaging (MRI) images of the brain. MMORF is capable of simultaneously optimising both displacement and rotational transformations within a single registration framework by leveraging rich information from multiple scalar and tensor modalities. The regularisation employed in MMORF promotes local rigidity in the deformation, and we have previously demonstrated how this effectively controls both shape and size distortion, leading to more biologically plausible warps.

Parasiticide use and obesity in dogs with sudden acquired retinal degeneration syndrome.

Objective: To investigate parasiticide use and describe signalment features in patients with sudden acquired retinal degeneration syndrome (SARDS).

Animals: Retrospective case-control study of dogs with (n = 71) and without (136) SARDS.

Methods: Parasiticide use, presentation season, weight, body condition, and signalment were compared between dogs diagnosed with SARDS and the reference population by use of descriptive statistics and logistic regression.

Role of artificial intelligence in critical care nutrition support and research.

Nutrition plays a key role in the comprehensive care of critically ill patients. Determining optimal nutrition strategy, however, remains a subject of intense debate. Artificial intelligence (AI) applications are becoming increasingly common in medicine, and specifically in critical care, driven by the data-rich environment of intensive care units.

The effects of genetic and modifiable risk factors on brain regions vulnerable to ageing and disease.

We have previously identified a network of higher-order brain regions particularly vulnerable to the ageing process, schizophrenia and Alzheimer's disease. However, it remains unknown what the genetic influences on this fragile brain network are, and whether it can be altered by the most common modifiable risk factors for dementia. Here, in ~40,000 UK Biobank participants, we first show significant genome-wide associations between this brain network and seven genetic clusters implicated in cardiovascular deaths, schizophrenia, Alzheimer's and Parkinson's disease, and with the two antigens of the XG blood group located in the pseudoautosomal region of the sex chromosomes.

Superficial keratectomy for the treatment of spontaneous chronic corneal epithelial defects in dogs.

Objective: To report the outcome of superficial keratectomy with bandage contact lens placement for the treatment of spontaneous chronic corneal epithelial defects (SCCEDs) in dogs.

Methods: Patients that underwent a superficial keratectomy with bandage lens placement for the treatment of one or more SCCEDs were retrospectively included in the study. Signalment, eye(s) affected, prior medical therapy and any procedures performed, post-operative medical therapy, healing rate, and any post-operative complications were recorded.

Free labial mucocutaneous graft for eyelid reconstruction in four dogs.

Purpose: To describe a technique for eyelid margin reconstruction following large mass resection utilizing a free labial mucocutaneous graft.

Methods: Four dogs (4 eyes) underwent en bloc eyelid mass excision under general anesthesia. Measurements were made of the mass followed by free labial mucocutaneous graft retrieval, resection of the mass, and then transplantation of retrieved region of labial mucocutaneous tissue into the resulting defect.

The relationship between body mass index and mortality is not linear in patients requiring venovenous extracorporeal support.

Objective: Morbid obesity may influence candidacy for venovenous extracorporeal membrane oxygenation (VVECMO) support. Indeed, body mass index (BMI) >40 is considered to be a relative contraindication due to increased mortality observed in patients with BMI above this value. There is scant evidence to characterize this relationship beyond speculating about the technical challenges of cannulation and difficulty in optimizing flows.

Bayesian methods: a potential path forward for sepsis trials.

Background: Given the success of recent platform trials for COVID-19, Bayesian statistical methods have become an option for complex, heterogenous syndromes like sepsis. However, study design will require careful consideration of how statistical power varies using Bayesian methods across different choices for how historical data are incorporated through a prior distribution and how the analysis is ultimately conducted. Our objective with the current analysis is to assess how different uses of historical data through a prior distribution, and type of analysis influence results of a proposed trial that will be analyzed using Bayesian statistical methods.

Time for You: A process evaluation of the rapid implementation of a multi-level mental health support intervention for frontline workers during the COVID-19 pandemic.

The coronavirus (COVID-19) pandemic had wide-ranging negative impacts on mental health. The pandemic also placed extraordinary strain on frontline workers who were required to continue working and putting themselves at risk to provide essential services at a time when their normal support mechanisms may not have been available. This paper presents an evaluation of the Time for You service, a rapidly developed and implemented intervention aimed at providing frontline workers with quick access to flexible online mental health support.

The impact of founder personalities on startup success.

Startup companies solve many of today's most challenging problems, such as the decarbonisation of the economy or the development of novel life-saving vaccines. Startups are a vital source of innovation, yet the most innovative are also the least likely to survive. The probability of success of startups has been shown to relate to several firm-level factors such as industry, location and the economy of the day.

Modifying Candidacy and Management to Improve Extracorporeal Support During Supply-Demand Mismatch.

Background: Candidacy for venovenous extracorporeal membrane oxygenation is dictated by ECMO to Rescue Lung Injury in Severe ARDS (EOLIA) criteria. We evaluated the effect of modifying candidacy on the basis of escalating demand and limited resources.

Methods: We retrospectively reviewed adult patients diagnosed with COVID-19-related severe acute respiratory distress syndrome who failed to respond to conventional ventilation and required extracorporeal support at our institution.

Objective: To investigate the effect of the addition of dexmedetomidine (BLD) to retrobulbar blockade with combined lignocaine and bupivacaine on nociception.

Animals: A total of 17 eyes from 15 dogs.

Methods: Prospective, randomized, masked clinical comparison study.

The sporting resilience model: A systematic review of resilience in sport performers.

Unlabelled: We systematically reviewed resilience research in sport and exercise psychology. Sample included 92 studies comprising empirical qualitative and quantitative studies, mixed-method studies, review studies and conceptual/theoretical studies on psychological resilience in sports context. From the findings, we synthesized an evidence-based sport-specific definition and meta-model of "Sporting Resilience.

Acceptance of Acute Kidney Injury Alert by Providers in Cardiac Surgery Intensive Care Unit.

Background: Acute kidney injury (AKI) is a common complication after cardiac surgery and is associated with worse outcomes. Its management relies on early diagnosis, and therefore, electronic alerts have been used to alert clinicians for development of AKI. Electronic alerts are, however, associated with high rates of alert fatigue.

Amplitudes of resting-state functional networks - investigation into their correlates and biophysical properties.

Resting-state fMRI studies have shown that multiple functional networks, which consist of distributed brain regions that share synchronised spontaneous activity, co-exist in the brain. As these resting-state networks (RSNs) have been thought to reflect the brain's intrinsic functional organization, intersubject variability in the networks' spontaneous fluctuations may be associated with individuals' clinical, physiological, cognitive, and genetic traits. Here, we investigated resting-state fMRI data along with extensive clinical, lifestyle, and genetic data collected from 37,842 UK Biobank participants, with the object of elucidating intersubject variability in the fluctuation amplitudes of RSNs.

Serial Convalescent Plasma Infusions for the Initial COVID-19 Infections in the Appalachian Region of West Virginia.

Purpose: The rapid spread of SARS-CoV-2, the virus that is responsible for causing COVID-19, has presented the medical community with another example of when convalescent plasma (CP) is still used today. The ability to standardize CP at the onset of a pandemic is unlikely to exist in a reliable and uniformly reproducible way. We hypothesized that CP of unknown strength given in a serial manner will promote health and reduce mortality in those inflicted with COVID-19.

Development and Use of an Ex-Vivo In-Vivo Correlation to Predict Antiepileptic Drug Clearance in Patients Undergoing Continuous Renal Replacement Therapy.

Objectives: Results from previous ex-vivo continuous renal replacement therapy (CRRT) models have successfully demonstrated similar extraction coefficients (EC) identified from in-vivo clinical trials. The objectives of this study are to develop an ex-vivo in-vivo correlation (EVIVC) model to predict drug clearance for commonly used antiepileptics and to evaluate similarity in drug extraction across different CRRT modalities to extrapolate dosing recommendations.

Methods: Levetiracetam, lacosamide, and phenytoin CRRT clearance was evaluated using the Prismaflex CRRT system and M150 hemodiafilters using an albumin containing normal saline (ALB-NS) vehicle with 3 different albumin concentrations (2 g/dL, 3 g/dL, and 4 g/dL) and a human plasma vehicle at 3 different effluent flow rates (1 L/hr, 2 L/hr, and 3 L/hr).

Cannulate, extubate, ambulate approach for extracorporeal membrane oxygenation for COVID-19.

Objective: We compared outcomes in patients with severe COVID-19 versus non-COVID-19-related acute respiratory distress syndrome (ARDS) managed using a dynamic, goal-driven approach to venovenous extracorporeal membrane oxygenation (ECMO).

Methods: We performed a retrospective, single-center analysis of our institutional ECMO registry using data from 2017 to 2021. We used Kaplan-Meier plots, Cox proportional hazard models, and propensity score analyses to evaluate the association of COVID-19 status (COVID-19-related ARDS vs non-COVID-19 ARDS) and survival to decannulation, discharge, tracheostomy, and extubation.

SARS-CoV-2 is associated with changes in brain structure in UK Biobank.

There is strong evidence of brain-related abnormalities in COVID-19. However, it remains unknown whether the impact of SARS-CoV-2 infection can be detected in milder cases, and whether this can reveal possible mechanisms contributing to brain pathology. Here we investigated brain changes in 785 participants of UK Biobank (aged 51-81 years) who were imaged twice using magnetic resonance imaging, including 401 cases who tested positive for infection with SARS-CoV-2 between their two scans-with 141 days on average separating their diagnosis and the second scan-as well as 384 controls.

Optimizing the nutrition support care model: Analysis of survey data.

Background: Malnutrition is underrecognized and underdiagnosed, despite high prevalence rates and associated poor clinical outcomes. The involvement of clinical nutrition experts, especially physicians, in the care of high-risk patients with malnutrition remains low despite evidence demonstrating lower complication rates with nutrition support team (NST) management. To facilitate solutions, a survey was designed to elucidate the nature of NSTs and physician involvement and identify needs for novel nutrition support care models.
