The whole tumor volume and the solid part volume were associated with DFS. In particular, the solid part volume was a very useful factor for predicting prognosis in clinical stage IA NSCLC.

Despite recent increases in the number of female physicians graduating in Japan, their premature resignations after childbirth are contributing to the acute shortage of physicians. Previous Japanese studies have explored supportive measures in the workplace, but have rarely focused on the specific problems or concerns of physician-mothers. Therefore, this study explored the challenges facing Japanese physician-mothers in efforts to identify solutions for their retention. Open-ended questionnaires were mailed to 646 alumnae of Juntendo University School of Medicine. We asked subjects to describe their opinions about 'The challenges related to female physicians' resignations'. Comments gathered from alumnae who graduated between 6 and 30 years ago and have children were analyzed qualitatively. Overall, 249 physicians returned the questionnaire (response rate 38.5%), and 73 alumnae with children who graduated in the stated time period provided comments. The challenges facing physician-mothers mainly consisted of factors associated with Japanese society, family responsibilities, and work environment. Japanese society epitomized by traditional gender roles heightened stress related to family responsibilities and promoted gender discrimination at work environment. Additionally, changing Japanese society positively influenced working atmosphere and husband's support. Moreover, the introduction of educational curriculums that alleviated traditional gender role was proposed for pre-and post-medical students. Traditional gender roles encourage discrimination by male physicians or work-family conflicts. The problems facing female physicians involve more than just family responsibilities: diminishing the notion of gender role is key to helping retain them in the workforce.

Purpose The purpose of this study was to evaluate whether the bone morphology of the hip affects the range of motion (ROM) in total hip arthroplasty (THA). Methods Using the CT data of 63 patients who underwent THA, we calculated the ROM of flexion (Flex), internal rotation (Int-R) and external rotation (Ext-R) using 3D dynamic analysis software. We measured the distance between the anterior surface of the stem and anterior aspect of the greater trochanter (GTa length) at the cutting point and between the tip of the antero-inferior iliac spine (AIIS) and coronal plane of both femoral heads (AIIS length), as a parameter of the femur and pelvis, respectively. The relationship between the ROM, bone anatomy and impingement site was evaluated. Results We found a significant decrease in the ROM of Flex and the Int-R to be inversely proportional to the GTa and AIIS length. In Flex and Int-R, the anterior intertrochanteric region often impinges on the AIIS in patients with larger bone anatomy. Conclusions We demonstrated that the bone morphology of the hip substantially affects the ROM of Flex and Int-R, especially in patients with large bone anatomy. For these patients we should consider bony impingement in THA.
