We aimed to evaluate the clinical benefits of dexmedetomidine (DEX) in comparison with the standard of care (SOC) sedation in critically ill, septic patients. Electronic databases (PubMed, EMBASE, Cochrane Central, Scopus, and Google Scholar) were systematically searched to identify only randomized clinical trials performed up until February 12, 2021. The primary outcomes were 28-day mortality, 90-day mortality, and intensive care unit (ICU) length of stay (LOS). We calculated risk ratios (RRs), 95% confidence intervals (CIs) for dichotomous data, and weighted mean differences (WMDs) for continuous data using a random-effects model. Seven randomized clinical trials were included, with a total of 529 patients in the DEX group and 520 patients in the SOC group. Compared with SOC, DEX was associated with a nonstatistically significant reduced 28-day mortality (RR = 0.76; 95% CI [0.51, 1.14]; = 0.19), 90-day mortality (RR = 0.94; 95% CI [0.75, 1.18]; = 0.60), and ICU LOS (WMD = -0.85; 95% CI [-2.60, 0.90]; = 0.34). We conclude that among septic patients on sedation, the use of DEX in the ICU demonstrated no significant difference from SOC sedation protocols with respect to 28-day mortality, 90-day mortality, and total ICU LOS. Our findings suggest that DEX does not confer clinical benefit over SOC sedation in critically ill patients with sepsis.

Behavioral symptoms and treatment challenges for patients living with dementia: Hospice clinician and caregiver perspectives.

Introduction: Dementia affects one in three older adults over age 85 and individuals with dementia constitute the fastest growing population of patients entering hospice care. While cognitive impairment is the hallmark of dementia, behavioral symptoms are reported in nearly all patients with advanced dementia, contributing to both the complexity of end-of-life care and caregiver burden.
Methods: This qualitative study involved semi-structured interviews with prescribing hospice clinicians and caregivers of patients living with dementia who previously received hospice services.

Animal models are pivotal in disease research and the advancement of therapeutic methods. The translation of results from these models to clinical applications is enhanced by employing technologies which are consistent for both humans and animals, like Magnetic Resonance Imaging (MRI), offering the advantage of longitudinal disease evaluation without compromising animal welfare. However, current animal MRI techniques predominantly employ 2D acquisitions due to constraints related to organ size, scan duration, image quality, and hardware limitations.

Background: We aimed to develop a transcatheter aortic valve replacement (TAVR) sizing algorithm and implantation method to facilitate safe and effective TAVR without contrast use in patients with severe chronic kidney disease (CKD) who do not yet require renal replacement therapy. Patients with CKD are a challenging patient subset to treat using standard TAVR care pathways which most usually require the use of iodinated contrast media both during gated computed tomography (CT) angiography sizing, and valve deployment. Iodinated contrast exposure may worsen kidney function in a dose-dependent fashion, and may result in a need for renal replacement therapy.

Background And Objective: Exposure keratopathy (EPK) is characterized by punctate erosions of the corneal epithelium, mainly located in the lower third of the cornea. In the Pediatric Intensive Care Unit (PICU), an incidence of 19-25 % has been reported. The objective of this study was to describe the frequency, risk factors, and time to resolution of exposure keratitis in PICU patients.

Article Synopsis
- Propofol is frequently used as a sedative for critically ill adults on mechanical ventilation, but its link to elevated triglyceride levels and acute pancreatitis remains unclear.
- The study observed over 11,000 ICU patients receiving propofol, finding that about 21.7% developed hypertriglyceridemia, and those with high triglycerides had a significantly increased risk of pancreatitis.
- Despite the association between triglyceride levels and pancreatitis, acute pancreatitis is rare in this population, suggesting other contributing factors may be involved.
