Evaluation of Dexmedetomidine Dosing in Obese Critically Ill Patients.

J Pharm Pract 2021 Jun 10:8971900211021578. Epub 2021 Jun 10.

Department of Pharmacy, The Ohio State University Wexner Medical Center, Columbus, OH, USA.

Associations between feeding behaviors collected from an automated milk feeder and disease in group-housed dairy calves in Ontario: A cross-sectional study.

J Dairy Sci 2021 Jun 4. Epub 2021 Jun 4.

Department of Population Medicine, University of Guelph, Guelph, ON, Canada, N1G 2W1. Electronic address:

The adoption of automated milk feeders and group housing of preweaning dairy calves has become more common in Canada; however, disease detection in group-housed calves remains a challenge. The aim of this cross-sectional study was to assess whether feeding behavior data collected from a single point in time could be used to aid in the detection of neonatal calf diarrhea (NCD), bovine respiratory disease (BRD), and general disease, in preweaning group-housed calves being fed via an automated milk feeder. The data used was collected in an earlier study. Read More

The anti-inflammatory effects of cannabidiol and cannabigerol alone, and in combination.

Pulm Pharmacol Ther 2021 Jun 1;69:102047. Epub 2021 Jun 1.

Sackler Institute of Pulmonary Pharmacology, Institute of Pharmaceutical Science, King's College London, SE1 9NH, London, United Kingdom. Electronic address:

Introduction/background And Purpose: Studies with Cannabis Sativa plant extracts and endogenous agonists of cannabinoid receptors have demonstrated anti-inflammatory, bronchodilator, and antitussive properties in the airways of allergic and non-allergic animals. However, the potential therapeutic use of cannabis and cannabinoids for the treatment of respiratory diseases has not been widely investigated, in part because of local irritation of airways by needing to smoke the cannabis, poor bioavailability when administered orally due to the lipophilic nature of cannabinoids, and the psychoactive effects of Δ9-Tetrahydrocannabinol (Δ9-THC) found in cannabis. The primary purpose of this study was to investigate the anti-inflammatory effects of two of the non-psychotropic cannabinoids, cannabidiol (CBD) and cannabigerol (CBG) alone and in combination, in a model of pulmonary inflammation induced by bacterial lipopolysaccharide (LPS).

Mitochondrial Succinate Metabolism and Reactive Oxygen Species Are Important but Not Essential for Eliciting Carotid Body and Ventilatory Responses to Hypoxia in the Rat.

Antioxidants (Basel) 2021 May 25;10(6). Epub 2021 May 25.

Institute of Clinical Sciences, University of Birmingham, Edgbaston, Birmingham B15 2TT, UK.

Reflex increases in breathing in response to acute hypoxia are dependent on activation of the carotid body (CB)-A specialised peripheral chemoreceptor. Central to CB O-sensing is their unique mitochondria but the link between mitochondrial inhibition and cellular stimulation is unresolved. The objective of this study was to evaluate if ex vivo intact CB nerve activity and in vivo whole body ventilatory responses to hypoxia were modified by alterations in succinate metabolism and mitochondrial ROS (mitoROS) generation in the rat.

Avian antibodies (IgY) targeting spike glycoprotein of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) inhibit receptor binding and viral replication.

PLoS One 2021 28;16(5):e0252399. Epub 2021 May 28.

Scaled Microbiomics, LLC, Hagerstown, MD, United States of America.

Background: The global pandemic of Coronavirus infectious disease 2019 (COVID-19), caused by SARS-CoV-2, has plunged the world into both social and economic disarray, with vaccines still emerging and a continued paucity of personal protective equipment; the pandemic has also highlighted the potential for rapid emergence of aggressive respiratory pathogens and the need for preparedness. Avian immunoglobulins (IgY) have been previously shown in animal models to protect against new infection and mitigate established infection when applied intranasally. We carried out a proof-of-concept study to address the feasibility of using such antibodies as mucosally-applied prophylaxis against SARS-CoV-2. Read More

A Call for the World Health Organization to Create International Classification of Disease Diagnostic Codes for Post-Intensive Care Syndrome in the Age of COVID-19.

World Med Health Policy 2021 Feb 22. Epub 2021 Feb 22.

Post-intensive care syndrome (PICS), a condition found in survivors of critical illness, is characterized by persistent physical, cognitive, and psychological sequelae that impact the quality of life after discharge from an intensive care unit (ICU). At present, there are no International Classification of Disease (ICD) billing codes for this condition. Without financial alignment, clinicians cannot diagnose PICS, hindering tracking of its prevalence and impeding policy development for this condition. Read More
