Rhabdomyolysis is characterized by rapid muscle breakdown and release of intracellular muscle components into the circulation. Acute renal injury is the most common and fatal complication of rhabdomyolysis. The current literature emphasizes the importance of preventing rhabdomyolysis and finding the benefits of sodium bicarbonates and mannitol in its prevention. A PubMed database search for the keywords "Rhabdomyolysis," "Sodium bicarbonate use in rhabdomyolysis," "Mannitol use in rhabdomyolysis," and a Medical Subject Headings (MeSH) search using the keyword "Rhabdomyolysis; Acute Kidney Injury (Subheading-Prevention and control)" generated 10,005 articles overall. After a thorough application of inclusion/exclusion criteria, 37 relevant studies were selected for this literature study. This analysis demonstrates that aggressive early volume resuscitation with normal saline should continue being the principal focus of therapy, and the use of sodium bicarbonate and mannitol in practical situations is not entirely justified. This article also emphasizes the need for future research on this topic and provides recommendations for future research.
The gut microbiota in humans communicates to the central nervous system through the gutbrain axis, and this communication functions in a bidirectional manner. The backbone of this axis is via the vagus nerve allowing the communication. Research on the functionality of the gut-brain axis is present; however, analysis of the diversity and stratification of the gut microbiota is in its infancy. Through the exploration of various studies focusing on the role of the gut microbiota and its effects on the efficacy of selective serotonin receptor inhibitors (SSRIs) in depression management, many promising alterations in constructive changes have emerged. It has become evident that a set of quantifiable microbial markers have been identified as consistent in the stools of depressive subjects that can be further used to determine the severity of disease progression-the presence of certain bacterial species being a common thread amongst the therapeutic bacteria for depression management. The vagus nerve's role in the gut-brain axis, which is vital to carry out any constructive alterations in the gut microbiota, has been strengthened through evidence of SSRIs depending on the vagus to execute therapeutic effects. This review will focus on the interaction between the diversity of the gut microbiota and investigate its link with depression.
Delirium is a multifactorial syndrome and is described as an acute brain dysfunction seen commonly in post-cardiac surgery patients. The prevalence of post-operative Delirium (POD) ranges from 11.4% to 55%, depending on the diagnostic tool and type of study. Confusion Assessment Method for the Intensive Care Unit (CAM-ICU) and the Intensive Care Delirium Screening Checklist (ICDSC) are the two most used and recommended tools by the Society of Intensive Care Medicine. Annual delirium-related healthcare costs in the United States (US) range from 6.6 to 20.4 billion USD in ICU patients. However, delirium in cardiac ICU (CICU) is underdiagnosed and warrants vigorous workup. The risk factors for delirium in CICU can be classified as modifiable, non-modifiable, and cardiac surgical causes. After cardiac procedures, delirium is associated with increased mortality, increased length of hospital stay, loss of functional independence, increased hospital costs, and an independent predictor of death 10 years postoperatively. Non-pharmacological measures such as avoiding delirium-risk medications, early physical rehabilitation, occupational therapy, and sleep improvement strategies have shown significant benefits in decreasing delirium. Pharmacological options are limited for use in CICU, and a need for future studies in this topic is in demand.
Eosinophilic granulomatosis with polyangiitis (EGPA) is a rare autoimmune systemic necrotizing vasculitis of blood vessels that often presents with hypereosinophilia. Cardiac involvement in EGPA directly correlates with the mortality of patients with the disease and is a central part of the disease process. The evaluation and treatment of cardiac anomalies are vital in patients with EGPA. The frequency with which cardiac involvement is seen in the disease process makes early diagnosis crucial in all patients with EGPA. Early treatment has been proven to reverse or cause the disease to go into remission. Several studies have shown that cardiac magnetic resonance (CMR) imaging is the most sensitive and best early indicator of cardiovascular involvement in EGPA. CMR routinely outperforms other diagnostic techniques such as ECG (echocardiography) and CTA (computed tomography angiography) in the detection of cardiac anomalies and should be a part of the standardized assessment of all patients with EGPA. CMR is also a non-invasive diagnostic tool that can also outperform biopsy in the detection of EGPA cardiac involvement. CMR is also a valuable technique that can be used to monitor disease progression while treatment is being performed. Although long-term research studies have yet to show these benefits, the studies that are available today provide ample evidence that shows CMR imaging could ultimately help bring down mortality rates currently seen in EGPA patients if it is used as an evaluation tool from initial diagnosis and throughout the entire course of disease management.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
