While women tend to experience more severe psychiatric and neurobehavioral symptoms following traumatic brain injury (TBI), the connection between sex and post-TBI depression remains poorly understood. To explore the potential association between sex and post-TBI depression, we conducted a systematic review and meta-analysis, including studies with participants who had no prior diagnosis of depression. Thirteen studies met the criteria for inclusion, collectively investigating a cohort of 449,471 individuals with TBI.

Cognitive decline is common among older individuals, and although the underlying brain mechanisms are not entirely understood, researchers have suggested using EEG frontal alpha activity during general anaesthesia as a potential biomarker for cognitive decline. This is because frontal alpha activity associated with GABAergic general anaesthetics has been linked to cognitive function. However, oscillatory-specific alpha power has also been linked with chronological age.

Delirium is an acute brain disorder associated with disorganized thinking, difficulty focusing, and confusion that commonly follows major surgery, severe infection, and illness. Older patients are at high risk for developing delirium during hospitalization, which may contribute to increased morbidity, longer hospitalization, and increased risk of institutionalization following discharge. The pathophysiology underlying delirium remains poorly studied.

Article Synopsis
  • - Absence seizures are short episodes where individuals experience impaired consciousness and unresponsiveness, and their underlying neuronal mechanisms are not fully understood, though they are observed in both humans and an awake female rat model.
  • - In this model, researchers found that there are decreases in overall neuronal firing during seizures, but patterns of activity among individual neurons vary, including initial surges in firing followed by sustained decreases.
  • - Notably, changes in brain activity begin 40-60 seconds prior to a seizure, showing a decline in low-frequency brain waves and behavioral activity, while higher-frequency brain activity and neuronal rhythmicity increase, indicating that significant brain state shifts occur before seizures happen.

Guidelines support lowering cholesterol to decrease atherosclerotic cardiovascular disease (ASCVD) risk across the entire lifespan with intensive lifestyle intervention, as well as statin and non-statin pharmacotherapy for those at highest risk. Modest improvements in the initiation, use, and adherence to statin therapy in patients with ASCVD have occurred over the past decades. However, studies continue to document a less than desired implementation of guidelines highlighting a substantial and persistent treatment gap.

Introduction: Opioids are the most commonly used analgesic in the postoperative setting. However, few studies have analyzed the impact of high inpatient opioid use on outcomes following surgery, with no current studies assessing its effect on patients undergoing spinal fusion for an adult spinal deformity (ASD). Thus, the aim of this study was to investigate risk factors for high inpatient opioid use, as well as to determine the impact of high opioid use on outcomes such as adverse events (AEs), hospital length of stay (LOS), cost of hospital admission, discharge disposition, and readmission rates in patients undergoing spinal fusion for ASD.

Introduction: Total knee arthroplasty (TKA) and total hip arthroplasty (THA) are outstanding options for many older patients at the discretion of the patient and the surgeon. As patients turn 65 years, greater than 98% of the US population becomes eligible for Medicare, and this represents a time of changing healthcare coverage for many.

Methods: Patients undergoing elective TKA and THA were abstracted from the 2012 to 2018 National Surgical Quality Improvement Program database.

Article Synopsis
  • * Researchers analyzed data from 2,620 adult patients who had surgery for SDH, categorizing them by their frailty level using a modified frailty index (mFI).
  • * Results showed that higher frailty (mFI = 2+) was linked to a longer hospital stay and a higher likelihood of nonroutine discharge, but did not significantly affect in-hospital mortality rates.
