The Effects of Sleep Deprivation, Caffeine, and Alcohol on Simulated Neurosurgical Performance by Daniel J Guillaume in Crimson publishers: Surgical Medicine Open Access Journal

Crimson Publishers: Surgical Medicine Open Access Journal

Objectives:We hypothesized that sleep deprivation, caffeine intake, and alcohol consumption the night prior to simulated microneurosurgery may impact performance on a virtual reality neurosurgical simulator.

Patients and Methods: After IRB approval, trainees practiced a simulated bimanual arachnoid dissection microsurgical task on the NeuroTouch Neurosurgical simulator (National Research Council, Canada) until it was mastered. For each participant, the task was repeated several times following sleep deprivation, caffeine intake and the morning after a social gathering where blood alcohol content (BAC) was measured. Each time the task was performed, the participants documented variables on a questionnaire. Performance metrics included: task duration, left or right hand excessive force, number of incorrect or correct fibers cut, and overall score based on several measurements.

Improving Outcome for the Elderly Surgical Patients in a Singapore Teaching Hospital by Si Ching Lim*, Peter Chow, Peter CL Chow, Fuyin Li, Swee Sim Hiew, Lau Soy Soy and Zhang Di in Crimson Publishers: Surgical Medicine Open Access Journal The elderly patients admitted under surgery have longer lengths of stay and develop multiple complications during their hospital stay particularly with delirium, medical complications and functional decline. A Geriatrician’s input was helpful to identify incident and postop delirium early and put in measures to improve outcome, together with better nursing care and pharmacist’s input to reduce harm from medications. https://crimsonpublishers.com/smoaj/fulltext/SMOAJ.000537.php For more open access journals in Crimson Publishers Please click on:  https://crimsonpublishers.com/ For more articles on Surgical Medicine Open Access Journal Please click on link:   https://crimsonpublishers.com/smoaj/index.php Follow on ...

Role of Antioxidants in the Treatment of Male Infertility_Crimson publishers Role of Antioxidants in the Treatment of Male Infertility by  Khaled Gadallah in Surgical Medicine Open Access Journal Stress is defined as a general body response to initially threatening external or internal demands, involving the mobilization of physiological and psychological resources to deal with them. Recently, oxidative stress has become the focus of interest as a potential cause of male infertility. Normally, equilibrium exists between reactive oxygen species (ROS) production and antioxidant scavenging activities in the male reproductive organs. https://crimsonpublishers.com/smoaj/fulltext/SMOAJ.000509.php For more Open access journals in Crimson Publishers  Please click on: https: //crimsonpublishers.com/ For more articles in Open access journal of Innovation in Surgical Medicine Open Access Journal Please click on: https://crimsonpublishers.com/smoaj/index.php ...

Di ANA Technique for lipo marking. Adaptable Natural Abdominal Distraction. (For its' acronym in Spanish) by  Benavides Adan in Crimson Publishers: Surgical Medicine Open Access Journal Crimson Publishers:  Surgical Medicine Open Access Journal  The discovery of liposuction surges in need of trying to find solutions to lipodystrophies, avoiding extensive scars. In 1921 Dujarrier was awarded for being the first to do liposuction. The innovators of the concept of liposuction, as well as the material for carrying it out, were the surgeons Schrudde, Meyer, Arpad and Giorgio Fischer in 1974. In 1977, Illouz adapted a uterine Karman cannula adding suction to the practice of the process. In 1985 the introduction of syringe-assisted liposuction popularized by Fournier, partly simplified the intervention [1,2]. https://crimsonpublishers.com/smoaj/fulltext/SMOAJ.000516.php For more Open access journals in Crimson Publishers Please clickon:  https://crimso...
