Does total knee arthroplasty affect pelvic movements? A prospective comparative study.
Pathology in any segment of the spine-pelvis-lower extremity may impair the global postural balance, leading to compensatory alterations in other parts. The aim of this study was to compare the pelvic movements of patients suffering from knee osteoarthritis with patients who underwent total knee arthroplasty and healthy controls. ⋯ In this study, total knee arthroplasty was found to affect pelvic movements. It was thought that total knee arthroplasty changed these variables, probably owing to the frontal and sagittal plane alignment correction through surgery.

The aim of this study was to evaluate CD56 immunostaining in the stroma of benign and malignant ovarian epithelial neoplasms and associate the CD56 immunostaining with prognostic factors and survival in ovarian cancer. ⋯ Malignant ovarian neoplasms showed higher stromal CD56 immunostaining. As the prognostic value of natural killer in ovarian cancer is controversial, knowing the specific function of each cell present both in the tumor tissue and systemically may help guide successful immunotherapies in the near future.

Preoperative evaluation of sarcopenia in patients with colorectal cancer: a prospective study.
Colorectal cancer is the third most diagnosed malignant neoplasm in the world and the fourth leading cause of cancer mortality. The loss of muscle mass in oncological patients is the main aspect of cancer-related malnutrition. Associations between sarcopenia and poor outcomes, such as high postoperative mortality, chemotherapy toxicity, and reduced survival, have been recently described. The aim of this study was to prospectively assess the prevalence of preoperative sarcopenia in patients with colorectal cancer using validated methods to evaluate muscle strength, muscle mass, and physical performance. ⋯ Considering the criteria established by the EWGSOP, the prevalence of preoperative sarcopenia in colorectal cancer patients was 19.4%.

The prognostic significance of the heterologous component in uterine carcinosarcomas.
Uterine carcinosarcomas are aggressive, rare biphasic tumors with malignant epithelial and malignant sarcomatous components. The prognostic significance of the presence of extrauterine sarcoma (heterologous component) is controversial. Therefore, the aim of this study was to investigate the effect of heterologous components in uterine carcinosarcomas on disease-free survival, overall survival, and other prognostic factors. ⋯ The results obtained in this study showed that the presence of heterologous components in uterine carcinosarcoma is a prognostic factor that adversely affects both overall survival and disease-free survival. Lymphadenectomy and adjuvant radiotherapy have beneficial effects on both overall survival and disease-free survival.

The new prognostic factor in pre-intubation follow-up of critically ill patients: integrated pulmonary index monitoring.
The objective of this study was to identify the integrated pulmonary index in the follow-up of non-intubated critically ill patients in the emergency department and its efficacy in deciding on advanced airway application in comparison with the Glasgow Coma Scale. ⋯ The integrated pulmonary index monitoring provides an objective evaluation in the follow-up of critically ill patients with spontaneous breathing in the emergency department and is predictive in deciding on timely endotracheal intubation.
