The Role of Microglia in Perioperative Neuroinflammation and Neurocognitive Disorders.

Front Aging Neurosci 2021 28;13:671499. Epub 2021 May 28.

Department of Anesthesia and Perioperative Care, Center for Cerebrovascular Research, University of California, San Francisco, San Francisco, CA, United States.

The aseptic trauma of peripheral surgery activates a systemic inflammatory response that results in neuro-inflammation; the microglia, the resident immunocompetent cells in the brain, are a key element of the neuroinflammatory response. In most settings microglia perform a surveillance role in the brain detecting and responding to "invaders" to maintain homeostasis. However, microglia have also been implicated in producing harm possibly by changing its phenotype from its beneficial, anti-inflammatory state (termed M2) into an injurious pro-inflammatory state (termed M1); it is likely that there are intermediates states between these polar phenotypes and some consider that a gradient exists with a number of intermediates, rather than a strict dichotomy between M1 and M2.

Enhanced recovery after surgery for sleeve gastrectomies: improved patient outcomes.

Surg Obes Relat Dis 2021 May 3. Epub 2021 May 3.

Department of Surgery, Saint Barnabas Medical Center, RWJ Barnabas Health, Livingston, New Jersey. Electronic address:

Background: Enhanced Recovery After Surgery (ERAS) is a paradigm shift in perioperative care and incorporates patient-centered, evidence-based, and multidisciplinary team-developed pathways for a surgical specialty. ERAS pathways aim to reduce the patient's surgical stress response, optimize their physiologic function, facilitate recovery, and reduce the length of stay. The bariatric program at our institution was previously managed by many surgeons with anecdotal preferences, resulting in increased costs, lengths of stay, and opioid prescribing. Read More

Radiosurgery as a microsurgical adjunct: outcomes after microsurgical resection of intracranial arteriovenous malformations previously treated with stereotactic radiosurgery.

J Neurosurg 2021 Jun 11:1-12. Epub 2021 Jun 11.

1Department of Neurosurgery and Stanford Stroke Center, Stanford University Medical Center, Stanford.

Objective: Microsurgical resection of arteriovenous malformations (AVMs) can be aided by staged treatment consisting of stereotactic radiosurgery followed by resection in a delayed fashion. This approach is particularly useful for high Spetzler-Martin (SM) grade lesions because radiosurgery can reduce flow through the AVM, downgrade the SM rating, and induce histopathological changes that additively render the AVM more manageable for resection. The authors present their 28-year experience in managing AVMs with adjunctive radiosurgery followed by resection. Read More

Transplant Hepatectomy With Portacaval Shunt and MARS Therapy for Perioperative Catastrophe: A Series of Four Liver Transplant Cases.

Transplant Direct 2021 Mar 18;7(3):e674. Epub 2021 Feb 18.

University of Maryland School of Medicine, Baltimore, MD.

Increased worldwide focus on maximal donor utilization and transplantation of patients once considered too ill to survive liver transplantation may increase the otherwise rare frequency of catastrophic graft failure. Although the deleterious effects of an acutely failing allograft have been established for decades, the optimal strategy in this patient population in the perioperative period remains ill-defined.

Methods: A retrospective review of all liver transplant recipients with perioperative failure leading to transplant hepatectomy between January 1, 2014 and June 30, 2017 was performed. Read More

Surgical Management of Thoracolumbar Spondylodiscitis in End-Stage Renal Disease.

Indian J Orthop 2021 May 6;55(Suppl 1):176-181. Epub 2020 May 6.

Department of Orthopaedics, M S Ramaiah Medical College, Bangalore, India.

Background: In recent times due to the advancement of haemodialysis techniques, there is increase in the life span of the patients with end-stage renal disease, which tends to increase the risk of complications of bacteraemia due to skin penetration for blood access and leading to propensity for more skeletal and spinal complications. Hence, early diagnosis of spine infection and early initiation of appropriate therapy are important in ensuring successful treatment and preventing further morbidity.

Materials And Methods: The study included 22 males and 12 females who were known case of end-stage renal disease undergoing haemodialysis therapy and diagnosed with spondylodiscitis based on the clinical and radiological signs. Read More
