Objectives The BI-RADS classification system and the Gail Model are the scoring systems that contribute to the diagnosis of breast cancer. The aim of the study was to determine the contribution of Gail Model to the diagnosis of breast lesions that were radiologically categorized as BI-RADS 4A. Material and Methods We retrospectively examined the medical records of 320 patients between January 2011 and December 2020 whose lesions had been categorized as BI-RADS 4A. Radiological parameters of breast lesions and clinical parameters according to the Gail Model were collected. The relationship between malignant BI-RADS 4A lesions and radiological and clinical parameters was evaluated. In addition, the effect of the Gail Model on diagnosis in malignant BI-RADS 4A lesions was evaluated. Results Among radiological features, there were significant differences between lesion size, contour, microcalcification content, echogenicity, and presence of ectasia with respect to the pathological diagnosis (p <0.05). No significant difference was found between the lesions' pathological diagnosis and the patients' Gail score (p> 0.05). An analysis of the features of the Gail model revealed that there was no significant difference between the age of menarche, age at first live birth, presence of a first-degree relative with breast cancer, and a history of breast biopsy and the pathological diagnosis (p> 0.05). Conclusion As a conclusion Gail Model does not contribute to the diagnosis of BC, especially in patients with BI-RADS 4A lesions.

BACKGROUND Video games can be a valuable tool for surgery training. Individuals who interact or play video games, tend to have a better visuospatial ability when compared to non-gamers. Numerous studies suggest that video game experience is associated with faster acquisition, greater sharpening, and longer retention of laparoscopic skills. Given the neurocognitive complexity of surgery skill, multimodal approaches are required to understand how video game playing enhances laparoscopy skill. METHODS Data from thirteen surgeons with varying levels of laparoscopy experience and no video game experience, and 27 students with no laparoscopy experience and varying levels of video game experience performed standard laparoscopic training tasks. Their performance, subjective cognitive loading, and prefrontal cortical activity were recorded and analyzed. RESULTS The surgeons performed the tasks significantly faster, had significantly lower cognitive load as well as less left prefrontal activation, relative to the non-gamer novices. In gamer novices, the task completion time decreased significantly with increasing game experience. The cognitive load decreased significantly with increasing gaming experience in gamer novices and with laparoscopy experience in surgeons. CONCLUSION Our results suggest that along the dimensions of performance, cognitive load, and brain activity, the effects of video gaming experience on novice laparoscopy trainees are similar to those of real-world laparoscopy experience on surgeons. We believe that the neural underpinnings of surgery skill and its links with gaming experience need to be investigated further using wearable functional brain imaging.

Objectives The Relative Value Unit (RVU) is the main method of calculating surgeons' reimbursements and a tool for measuring the work of surgeons. Existing evidence shows that the work Relative Value Unit (wRVU) does not accurately represent surgeon's work. Therefore, the current study attempted to develop a local model to measure surgeons' work. Material and Methods This study was conducted in two main phases of determining the metrics and model development using quantitative and qualitative approaches from December 2019 to April 2021. Literature review, focused group discussions, and interviews were used to collect data. Con- tent analysis and Exploratory Data Analysis techniques were applied to analyze data. Results The findings demonstrated that patient's conditions (age, severity of disease at referring time, and comorbidities), disease specifications (time, complexity, physical effort, and risk), and provider characteristic (surgeon's willingness, imposed stress, and surgeon's skill) were important by 17, 51, and 32%, respectively, in determining surgeons' work. Conclusion Determining a fixed value for each procedure does not accurately estimate the amount of required surgeon's work for any procedure. Many factors, such as the patient's condition, surgeon's characteristics, and disease specification affect surgeons' work in the operation room. Proper measurement of the surgeon's work is an important step towards establishing equity in payment in the health system.
目的相对价值单位(Relative Value Unit, RVU)是计算外科医生报酬的主要方法和衡量外科医生工作的工具。现有证据表明，工作相对价值单位(wRVU)不能准确地代表外科医生的工作。因此，本研究试图建立一个局部模型来衡量外科医生的工作。材料和方法本研究从2019年12月至2021年4月，采用定量和定性方法，分确定指标和模型开发两个主要阶段进行。采用文献回顾、焦点小组讨论和访谈等方法收集数据。采用内容分析和探索性数据分析技术对数据进行分析。结果研究结果表明，患者的病情(年龄、转诊时疾病的严重程度和合并症)、疾病规格(时间、复杂性、体力劳动和风险)和提供者特征(外科医生的意愿、施加的压力和外科医生的技能)在决定外科医生的工作中分别占17%、51%和32%。结论确定每个手术的固定值并不能准确估计任何手术所需的外科医生工作量。影响外科医生在手术室工作的因素很多，如病人的病情、外科医生的特点、疾病的具体情况等。正确衡量外科医生的工作是在卫生系统中建立公平支付的重要一步。
