1 Comparison between logistic regression and machine learning algorithms on survival prediction of traumatic brain injuries
مقایسه رگرسیون لجستیک و الگوریتم های یادگیری ماشین در پیش بینی بقا از صدمات مغزی آسیب زا-2019
Purpose: To compare twenty-two machine learning (ML) models against logistic regression on survival prediction in severe traumatic brain injury (STBI) patients in a single center study. Materials andmethods: Datawas collected fromSTBI patients admitted to the Sichuan Provincial PeoplesHospital between December 2009 and November 2011. Twenty-two machine learning (ML) models were tested, and their predictive performance compared with logistic regression (LR) model. Receiver operating characteristics (ROC), area under curve (AUC), accuracy, F-score, precision, recall and Decision Curve Analysis (DCA) were used as performance metrics. Results: A total of 117 patientswere enrolled. AUC of all ML models ranged from86.3% to 94%. AUC of LRwas 83%, and accuracy was 88%. The AUC of Cubic SVM, Quadratic SVM and Linear SVM were higher than that of LR. The precision ratio of LR was 95% and recall ratio was 91%, both were lower than most ML models. The F-Score of LR was 0.93, which was only slightly better than that of Linear Discriminant and Quadratic Discriminant. Conclusions: The twenty-twoMLmodels selected have capabilities comparable to classical LR model for outcome prediction in STBI patients. Of these, Cubic SVM, Quadratic SVM, Linear SVM performed significantly better than LR.

2 Necessity of Repeat Computed Tomography Imaging in Isolated Mild Traumatic Subarachnoid Hemorrhage
ضرورت تکرار تصويربرداری تاموگرافی کامپيوتر در خونريزي سوباراکونوئيد تروماتيک خفيف-2018
I n a paper titled “Necessity of Repeat Computed Tomogra- phy Imaging in Isolated Mild Traumatic Subarachnoid Hem- orrhage,” Kumar et al1 challenged their institutional practice of managing patients with mild traumatic brain injuries (TBIs) with evidence of traumatic subarachnoid hemorrhage (tSAH). The practice at their facility (Kansas, United States) was for patients with mild TBIs with evidence of tSAH on an initial head computed tomography (CT) scan to be admitted to an intensive care unit setting for hourly observation checks and, even if unchanged, repeat head CT scans at 6 and 24 hours post injury. They referred in their article (and provided specific references) to several studies that had evaluated the necessity of intensive care unit admission and repeat cerebral imaging (usually specified time serial CT head scans) within 24 hours of a mild TBI with intracerebral hemorrhage. Most studies evaluated TBI in the context of any intracranial hemorrhage identified on the initial imaging. The debate that stimulated their submission and challenged practice was whether there was a subset with mild TBIs and only tSAH on initial imaging (without a known coagulopathy or on antiplatelet or anticoagulation medication) that was overusing resources, with associated costs, but also increasing unnecessary radiation exposure.

3 Helmet use and injuries in children’s bicycle crashes in the Gothenburg region
استفاده از کلاه ایمنی و جراحات در سقوط دوچرخه کودکان-2017
Aim: To investigate the use and protective effect of helmets in children injured in bicycle crashes and changes in injury patterns during a period of increased helmet use. Method: Injuries in 4246 children below 16 years of age, who attended an A&E ward after a bicycle crash in the Gothenburg region during 1993–2006, were analyzed. The injury severity was classified according to the Abbreviated Injury Scale. The occurrence of skull/brain injuries and facial injuries was analyzed for 3711 children with respect to injury severity, helmet use and demographic and crash-related factors. Changes in injury patterns during the period were analyzed for 4246 children with no regard to helmet use. The ratio of the number of subjects with head injuries to the number of subjects with extremity injuries of any severity and of at least moderate severity was used to estimate the protective effect of helmet at a population level. Results: Helmets were used by 40% of the injured children at the beginning of the period and by 80% at the end; much less frequently by teenagers, especially girls. The adjusted odds of serious or more severe skull/brain injuries and moderate or more severe facial injuries with a helmet were about one fourth of those without a helmet. The proportion of children with skull/brain injuries did not change significantly during the period. Serious or more severe skull/brain injuries were noted more often during the latter half of the period, most often in children without a helmet. The proportion of children with facial injuries decreased, and the proportion with injuries to the upper extremities increased, also for moderate and severe injuries. The ratio between the number of children with head injuries and the number with extremity injuries decreased for injuries of any severity and for moderate or more severe injuries. Conclusions: Bicycle helmets have an obvious protective effect against head injuries in children, regardless of the crash circumstances. Teenagers must be informed about the high risk of skull/brain injuries in bicycle crashes without a helmet. The increasing occurrence of injuries to the upper extremities needs attention.

4 Characteristics of Firearm Brain Injury Survivors in the Traumatic Brain Injury Model Systems (TBIMS) National Database: A Comparison of Assault and Self-Inflicted Injury Survivors
ویژگی های بازماندگان آسیب مغزی آتشین در پایگاه ملی سیستم های مدل آسیب های مغزی ضرب دیده (TBIMS): مقایسه تجاوز و ضرب خود تحمیلی آسیب بازماندگان-2017
Objective: To characterize and compare subgroups of survivors with assault-related versus self-inflicted traumatic brain injuries (TBIs) via firearms at the time of inpatient rehabilitation and at 1-, 2-, and 5-year follow-up. Design: Secondary analysis of data from the Traumatic Brain Injury Model Systems National Database (TBIMS NDB), a multicenter, longitudinal cohort study. Setting: Retrospective analyses of a subset of individuals enrolled in the TBIMS NDB. Participants: Individuals 16 years and older (NZ399; 310 via assault, 89 via self-inflicted injury) with a primary diagnosis of TBI caused by firearm injury enrolled in the TBIMS NDB. Interventions: Not applicable. Main Outcome Measures: Disability Rating Scale, Glasgow Outcome ScaleeExtended, sociodemographic variables (sex, age, race, marital status), injury-related/acute care information (posttraumatic amnesia, loss of consciousness, time from injury to acute hospital discharge), and mental health variables (substance use history, psychiatric hospitalizations, suicide history, incarcerations). Results: Individuals who survived TBI secondary to a firearm injury differed by injury mechanism (assault vs self-inflicted) on critical demographic, injury-related/acute care, and mental health variables at inpatient rehabilitation and across long-term recovery. Groups differed in terms of geographic area, age, ethnicity, education, marital status, admission Glasgow Coma Scale score, and alcohol abuse, suicide attempts, and psychiatric hospitalizations at various time points. Conclusions: These findings have implications for prevention (eg, mental health programming and access to firearms in targeted areas) and for rehabilitation planning (eg, by incorporating training with coping strategies and implementation of addictions-related services) for firearm-related TBI, based on subtype of injury.

هدف از توصیف و تعیین عوامل پیشگیرانه آسیب، آسیب و پس از آسیب مرتبط با نتیجه حرفه ای ۱ تا ۹ سال پس از خروج از برنامه ترکیب درمانی / آموزشی / آموزش حرفه‌ای ( VR ) است. روش‌های ۱۱۹ مشتری در سن کار زمانی که آسیب مغزی خود را بدست آوردند و در مرکز بین سال‌های ۲۰۰۲ و ۲۰۱۱ شرکت کرده بودند ، حداقل یک سال پس از خروج برای تعیین نتیجه حرفه‌ای آن‌ها به عنوان بخشی از یک بررسی / حسابرسی مداوم مورد پیگیری قرار گرفتند. تمام مشتریان آسیب جدی و شدید مغزی داشتند. مشتریان به عنوان داشتن یک نتیجه حرفه‌ای مثبت ( کار - پرداخت / داوطلبانه، تمام‌وقت / نیمه‌وقت یا تعهد کامل یا نیمه‌وقت ) یا نتیجه حرفه‌ای منفی ( بدون انجام کار یا تحصیلات ) طبقه‌بندی شدند. نتایج بیش از نیمی از مشتریان به یک نتیجه حرفه‌ای مثبت دست یافتند. طول مدت زمان خروج بین این مشتریان با یک نتیجه حرفه‌ای مثبت یا منفی تفاوت چندانی ندارد. نتیجه حرفه‌ای، از طریق توانایی ادراکی و حرکتی در خروج ، و جنسیت پیش‌بینی شد. این متغیرها با هم نتیجه حرفه‌ای ۷۶ درصد از مشتریان را طبقه‌بندی کردند. نتیجه‌گیری مشتریان با آسیب مغزی شدید / بسیار شدید می‌توانند به نتیجه حرفه‌ای مثبت پس از توانبخشی عصبی فشرده که شامل درمان‌های سنتی علاوه بر درمان و VR هستند ، دست یابند.
