INTRODUCTION: Deep brain stimulation (DBS) is an effective therapy for Parkinson's disease (PD). However, its effect in older patients is not extensively studied, as they are often excluded from DBS surgery due to concerns of complications or reduced benefit. We assessed clinical outcomes after subthalamic nucleus (STN) DBS in older patients (age > 75 years) with PD. METHODS: All PD patients above 75 years who underwent STN-DBS between 1999 and 2015 were included...

Postoperative cognitive dysfunction is common in the elderly. Endoplasmic reticulum stress (ER-stress) increases neuronal apoptosis after surgery, and chaperone molecules, such as heat shock proteins (HSPs), help reduce unfolded protein reactions, thereby promoting protein homeostasis. Mammal sirtuin1 (SIRT1)-mediated deacetylation of heat shock factor 1 (HSF1) upregulates HSF1 binding to the HSP70 promoter. Caloric restriction (CR) improves cognition in many neurodegenerative models. In this study, we evaluated whether CR improves impaired learning and memory after surgery by attenuating ER-stress in an SIRT1-dependent manner...

BACKGROUND: Resolution of inflammation is an active and dynamic process after surgery. Maresin 1 (MaR1) is one of a growing number of specialised pro-resolving lipids biosynthesised by macrophages that regulates acute inflammation. We investigated the effects of MaR1 on postoperative neuroinflammation, macrophage activity, and cognitive function in mice. METHODS: Adult male C57BL/6 (n=111) and Ccr2RFP/+ Cx3cr1GFP/+ (n=54) mice were treated with MaR1 before undergoing anaesthesia and orthopaedic surgery...

Of current obesity treatments, bariatric surgery induces the most weight loss. Given the marked increase in the number of bariatric surgeries performed, elucidating the mechanisms of action is a key research goal. We compared whole brain activation in response to high-energy dense (HED) vs. low-energy dense (LED) visual and auditory food cues before and approximately 4 months after Roux-en-Y Gastric Bypass (RYGB) (n = 16) and Sleeve Gastrectomy (SG) (n = 9). We included two control groups: a low-calorie diet weight loss group (WL) (n = 14) and a non-treatment group (NT) (n = 16)...

BACKGROUND: Neurobehavioral symptoms and cognitive dysfunction related to mood disorders are present in individuals with severe obesity. We sought to determine acute improvements in these symptoms and relationships with adiposity, inflammation, and insulin sensitivity after roux-en-y gastric bypass (RYGB) surgery. METHODS: The self-report Zung Depression Rating (ZDRS) and Neurotoxicity Rating (NRS) scales were administered before, and at 6-months after RYGB surgery in severely obese women (body mass index > 35 kg/m2 ; N = 19)...

The neurotoxicity of anesthetics on developing brain has been a focused issue for years. However, controversy exists between human and animal studies and surgery may be a potential reason for this. The discovery of glymphatic system, a pathway eliminating soluble substance from central nervous system (CNS), together with recent evidence that surgery-induced Aβ increase contributes to cognition dysfunction made us rethink about the influence of anesthetics on cognitive function. The function of glymphatic system was proved to be enhanced by sleep and sedation, so we assumed that under clinical situation Aβ1-40 whose accumulation played important role in cognitive dysfunction was increased by surgery and eliminated from CNS by glymphatic system...

BACKGROUND: The "magic triangle" in surgery and other disciplines consists of the demand for increasingly gentler forms of treatment, simultaneous cost reduction and the fundamental primacy of improving the quality of results. The digitalization of medicine offers a promising opportunity to do justice to this, also in the sense of "Surgery 4.0". The aim is to create a cognitive, collaborative diagnostics and treatment environment to support the surgeon. METHODS: In the sense of a "theory building" for analysis and planning, process modeling is the cornerstone for modern treatment planning...

Intractable epilepsy may have a more severe effect on children in comparison to adults because the motor, sensorial, and cognitive functions of children are still undergoing development. For this same reason, however, children maintain a greater potential for recovery from intractable epilepsy because of the remaining cerebral plasticity. Thus, after 2 unsuccessful antiepileptic medications, surgical intervention is recommended. Pre-surgical localization of the epileptogenic zone increases seizure-freedom post-surgery by 200% to 300%...

Thirty per cent of cancer patients develop brain metastases, with multiple combination or sequential treatment modalities available, to treat systemic or central nervous system (CNS) disease. Most patients experience toxicities as a result of these treatments, of which cognitive impairment is one of the adverse events most commonly reported, causing major impairment of the patient's quality of life. Areas covered: This article reviews the role of cancer treatments in cognitive decline of patients with brain metastases: surgery, radiotherapy, chemotherapy, targeted therapies, immunotherapies and hormone therapy...

Background: Meningioma patients are known to face cognitive deficits before and after surgery. We examined individual changes in cognitive performance over time and identified preoperative predictors of cognitive functioning 12 months after surgery in a large sample of meningioma patients. Methods: Patients underwent neuropsychological assessment (NPA) using CNS Vital Signs 1 day before (T0), and 3 (T3) and 12 (T12) months after surgery. Patients' sociodemographically-corrected scores on 7 cognitive domains were compared to performance of a normative sample using one-sample z tests and Chi-square tests of independence...

To address the, currently unmet, need for intra-operative safety-critical cognitive support in cardiac surgery, we have developed, validated, and implemented a series of customized checklists to address intra-operative emergencies, using a simulated operative setting. These crisis checklists are designed to provide cognitive and communication support to the operative team to reduce the likelihood of adverse events and improve adherence to best-practice guidelines. We recruited a number of content specialists including members of the hospital safety network and intraoperative cardiac surgery team members, and utilized a Delphi consensus method to develop procedure-specific guidelines for select intraoperative crises...

Traditional apprenticeships have been used through history as a teaching model for wide variety of skills. These apprenticeships are characterized by practical, on-the-job training in which the apprentice observes and assists a master in the completion of a task, and thereby learns the skills needed to complete that task on his or her own. Cognitive apprenticeship is a modified version of this traditional teaching method which is differentiated from the traditional apprenticeship model primarily by its educational goals; cognitive apprenticeships are used to teach skills which require internal thought processes which cannot be readily observed externally by the teacher or the student...
