A Nomogram Model to Predict Central Lymphnode Metastasis in Thyroid Papillary Carcinoma Suitable for Primary Hospitals
To establish and validate a suitable and practical nomogram for primary hospitals to predict the risk of central lymph node metastasis (CLNM) among thyroid papillary carcinoma (PTC) patients based on clinical and ultrasound characteristics among Chinese population,1000 PTC patients were retrospectively reviewed who underwent bilateral thyroidectomy or lobectomy plus central lymph node dissection(CLND) between June 2014 and September 2019 in Sun Yat-sen Memorial Hospital (Guangzhou, South China), and then LASSO regression analysis was performed to screen out the possible predictors. Another 200 PTC patients from the First Affiliated Hospital of Zhengzhou University (Zhengzhou, North China) who underwent bilateral thyroidectomy or lobectomy plus CLND between March 2019 and November 2020 were enrolled to construct the nomogram. The area under the receiver operating characteristic (ROC) curves (AUC), calibration curves and decision curve analysis (DCA) were used to evaluate the nomogram.
TOTEM RRMS : TestOsterone TreatmEnt on Neuroprotection and Myelin Repair in Relapsing Remitting Multiple Sclerosis
Centra nervous system (CNF) damage in multiple sclerosis (MS), are mainly attributed to myelin destruction, axonal abnormalities and subsequent degeneration, and are responsible for serious deficiencies. Current therapies are focused on the treatment of inflammation with several types of anti-inflammatory agents. However, there is an urgent need for innovative therapies promoting neuroregeneration and particularly myelin repair.
It has been demonstrated that testosterone can act through neural androgen receptors to promote proliferation and differentiation of oligodendrocyte precursors into mature oligodendrocytes in a cuprizone-induced animal model of demyelination. The rare clinical trials on testosterone are mainly exploratory. Here, we sought to demonstrate an effect of testosterone supplementation in testosterone-deficient patients in a multicenter, randomized, parallel-group, double-blind, placebo-controlled phase 2 trial.
The main objective will be to determine the neuroprotective and remyelinating effects of testosterone using tensor diffusion imaging techniques and thalamic atrophy analyzes.
As secondary objectives, we would like to study the impact of testosterone supplementation on other conventional and unconventional MRI parameters and on clinical outcomes (cognition, fatigue, quality of life, impact on work / activity and anxiety / depression).
A Phase II -b, Placebo-Controlled Trial Investigating the Efficacy, Safety and Pharmacokinetics of a Subcutaneous Etonogestrel Implant Combined With i.m. Testosterone Undecanoate for Male Contraception
Male volunteers receive a new hormonal contraceptive consisting of an implant releasing a hormone and hormone injections in order to investigate the suppressive effect on sperm production and reversibility of sperm production after end of treatment.
