The loss of muscle mass post-surgery confounds recovery efforts and leads to a delay in patient's ability to return to activities. Although the use of testosterone in aging and chronic muscle loss has been investigated, this study could prove short-term use of testosterone efficacious in preventing muscle atrophy due to surgery. We hypothesize that by bracketing an indexed knee surgery with testosterone undecanoate injections, post-surgical quadriceps muscle loss may be minimized. Determination of the effect of intra-muscular (IM) testosterone injections in preventing quadriceps muscle loss are measured by serial MRI and manual measurements of quadriceps cross-section.
The study is an observational analysis of patients' medical data recorded in a large-scale register, both retrospective (for patients operated and data recorded before 2018) and prospective (for data collected after 2018) in nature.Patients' medical data contained in the register will be analysed to determine the efficacy of the treatments they received during their follow-up at the investigation centre.

Background Surgery for mid and low rectal cancer is associated with relative high rates of incomplete mesorectal excisions and high rates of circumferential resection margin (CRM) involvement resulting in significant number of local recurrences. Moreover, patients with mid and low rectal cancer suffer from high rates of morbidity, permanent colostomies and impairment of quality of life. The transanal TME (TaTME) has been developed to improve the quality of TME surgery in mid and low rectal cancer. Study design The COLOR III trial is an international multicentre randomised study comparing short- and long-term outcomes of TaTME and laparoscopic TME for rectal cancer. The study will include a quality assessment phase before randomisation to ensure required competency level and uniformity of the new TaTME technique and the laparoscopic TME. During the trial clinical data will be reviewed centrally to ensure uniform quality. Endpoints The primary endpoint of the study is the local recurrence rate at 3-years follow-up. Secondary endpoints include sphincter saving procedures, short-term morbidity and mortality, involved circumferential resection margin (CRM), disease-free and overall survival at 3 and 5 years, completeness of mesorectum and quality of life. Statistics In laparoscopic TME the percentage of local recurrence at 3-years follow-up is estimated 5%. With the non-inferiority margin set at 4%, with a one-sided level of significance of 2.5% and a power of 80%, a total of 1104 patients is needed, 669 patients in the TaTME arm and 335 patients in the laparoscopic TME arm. All analyses will be performed on intention-to-treat basis. Main selection criteria Patients with histologically proven single mid or distal rectum carcinoma (0 to 10 cm from anal verge) at MRI, eligible for restorative surgery with a curative intent, are included. Patients with a T1 tumor suitable for local excision, T3 tumors with a suspected involved circumferential resection margin and T4 tumors are excluded. Hypothesis The hypothesis is that TaTME will result in a comparable local recurrence rate at 3-years follow-up with benefit of lower morbidity and conversions. Furthermore, because of direct endoscopic visualization, even in very low tumors a coloanal anastomosis can be created, resulting in a lower colostomy rate compared with laparoscopic and open resection. Because long-term outcomes are unknown, within a trial setting the technique can be standardized and quality control can be performed.
The purpose of this study is to establish viable cell culture system techniques for a variety of healthy and diseased tissues for use in future in vitro and in vivo research studies in tissue engineering.
