001) and those without a history of bowel surgery (P less then 0.001) and also more likely to signify CD in patients younger than 50 years (P=0.004), those without a history of bowel surgery (P=0.020), and when identified in the small intestine (P=0.032). In conclusion, intestinal PGM warrants a high suspicion for IBD and specifically CD, however, it should be interpreted with caution, especially in older patients or those with a history of prior intestinal surgery and in colorectal biopsies or specimens lacking severely active inflammation.Locally advanced breast cancer is typically treated with neoadjuvant chemotherapy to decrease tumor size and optimize surgical results. Cases of pathologic complete response, are associated with favorable long-term outcomes. Prexasertib The American Joint Committee on Cancer (AJCC) defines pathologic complete response as a lack of residual invasive disease in the breast or lymph nodes or only residual ductal carcinoma in situ. Three studies have examined the unique pattern of postneoadjuvant pure or predominantly pure intralymphatic carcinoma. These studies are small and the prognosis associated with this disease pattern is still unclear. The current study aims to describe clinicopathologic findings associated with pure and predominantly pure intralymphatic carcinoma postneoadjuvant chemotherapy. Electronic medical records were searched to identify patients treated with postneoadjuvant mastectomy between 2010 and 2017. Cases were included if they met the previously defined definitions for pure or predominantly pure intralymphatic carcinoma. Of 479 postneoadjuvant mastectomies, 5 patients had pure intralymphatic carcinoma and 6 patients had predominantly pure. Overall, 50% (3/6) of patients with predominantly pure pattern died of metastatic disease within 14 months of mastectomy, whereas 1 patient with pure intralymphatic carcinoma (ypN0) died of metastatic disease 25 months postmastectomy, revealing a better prognosis associated with pure intralymphatic carcinoma when compared with predominantly pure. The diligent gross examination is required to identify patients with both patterns of residual disease. A standardized approach to incorporating lymphovascular invasion into postneoadjuvant staging may be useful from both a clinical and research perspective. The published case numbers remain small and understanding the true clinical significance still depends on additional studies. To investigate if a disabled athlete's underlying disability and concussion history impacts the score on baseline testing from a disability modified Graded Symptoms Checklist (mGSC), Standardized Assessment of Concussion (SAC), and Wheelchair Error Scoring System (WESS).Retrospective chart review of 81 veteran wheelchair sport athletes who had baseline concussion evaluations. Demographic data including qualifying disability for the National Veterans Wheelchair Games, scores from the mGSC, SAC, and WESS were analyzed. 43% of wheelchair athletes reported a history of a concussion. Individuals with a history of a concussion displayed more symptoms on the mGSC (38.8 vs. 24.71, p=0.0378) as did those who had a qualifying disability in the brain disorder category (54.87 vs. amputees 24.07 and spinal cord disorders 24.9, p=0.0015). There was no difference in SAC exam or WESS scores based on concussion history or qualifying disability. Baseline symptom scores from a mGCS were higher in participants with a history of concussion, independent of their underlying disability, and higher if the athlete's disability was a brain disorder including MS and CVA. Scores on the SAC exam and WESS were not affected by the athlete's disability or concussion history. Baseline testing is integral for disabled athletes, especially those with underlying brain disorders and history of concussion.Baseline symptom scores from a mGCS were higher in participants with a history of concussion, independent of their underlying disability, and higher if the athlete's disability was a brain disorder including MS and CVA.

To investigate the morphological and functional changes of the tibialis anterior muscle following mirror visual feedback (MVF) combined with electromyographic biofeedback (EMG-BF) in poststroke patients. A total of 46 poststroke patients were randomly divided into three groups an MVF+EMG-BF group, an MVF group, and a control group. The MVF+EMG-BF group was treated with both MVF and EMG-BF, and the MVF group was treated with MVF alone. The morphological parameters, including the pennation angle (PA), muscle thickness (MT), and fascicle length (FL), were assessed. After four weeks of treatment, the PA and MT values were significantly increased in the MVF+EMG-BF and MVF groups (P<0.05). The increase of these values in the MVF+EMG-BF group were significantly greater than that for both metrics in the MVF and control groups (P<0.05), and those in the MVF group were greater than those in the control group (P<0.05). There was no significant difference in the FL value among the three groups as a result of the treatment. After the treatment, the neurological functions were all increased in three groups (P<0.05). A combination of MVF and EMG-BF appears to be an effective therapy for improving the motor function of the tibialis anterior muscle in poststroke patients. ChiCTR1800017050.ChiCTR1800017050.This study was performed to investigate pneumothorax characteristics and association with clinical outcomes in patients with osteosarcoma treated with apatinib. We retrospectively reviewed the medical records of osteosarcoma patients treated with apatinib between January 2016 and April 2020 at three institutions. We evaluated the prevalence, healing time, recurrence, severity, clinical management, and prognosis of pneumothorax in these patients. A total of 54 osteosarcoma patients who received apatinib treatment were enrolled in this study. Among them, 14 patients had pneumothorax. There were significant differences between the patients with and without pneumothorax with regard to the cavitating rate of lung metastases (92.86 vs. 32.50%, respectively, P  less then  0.001), objective response rate (42.86 vs. 10.00%, P = 0.013), disease control rate (85.71 vs. 42.50%, P = 0.006), 4-month progression-free survival (PFS) rate (57.10 vs. 20.00%, P  less then  0.001), and median PFS (5.65 vs. 2.90 months, P = 0.011).
