Effect of obesity on patterns and mechanisms of injury: Systematic review and meta analysis

Abstract

Trauma is one of the major causes of morbidity and mortality globally, especially in younger populations. With an increase in obesity globally, it is important to assess the potential differences in injury pattern and management of obese patients presenting with trauma compared to lean patients to try and improve patient care. This study aims to review the available literature comparing injury patterns between obese and non-obese patients. A systematic review of articles which assessed the association between obesity and different patterns of trauma and injury were assessed. Study quality was assessed using the Newcastle-Ottawa Scale. Data for injury patterns, type of trauma and patient course and outcome including length of ITU stay, length of intubation, length of hospital stay and mortality were collected. Summary data was assessed with random-effects meta-analysis. 21 studies with a total of 2,977,758 patients were identified. The majority of included patients had suffered blunt trauma. Lean patients were found to have a slightly increased risk of blunt trauma as a mechanism of injury (RR 1.02 p=<0.001), with a greater risk of head injury (lean patients RR 1.38 p=<0.001), reduced likelihood of extremity (lean RR 0.79 p=<0.0...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
