Filter by:Advances in patient selection, organ procurement and preservation, surgical technique, immunosuppression, and infection prevention have conferred significant decrease in rejection, infection, and subsequently improve cause-specific graft failure rates after kidney transplantation (KT). However, cardiovascular diseases (CVD) remained the main burden impairing both short-and long-term survival. Compared with the general population, conventional CVD risk factors, including obesity, liver and muscle insulin resistance, dyslipidemia, hypertension, and diabetes mellitus, are all highly prevalent in this population. Risk factors of these metabolic disorders are generally reported, including common risk factors and those specifically for kidney transplants, including long-term exposure to steroids and calcineurin inhibitors. Previous studies demonstrated that adenosine 5'-monophosphate (AMP)-activated protein kinase (AMPK) is a central regulator of multiple metabolic pathways and a key player in regulating cellular energy metabolism. Activation of AMPK by pharmacological agents may hold a considerable potential to reverse the metabolic abnormalities in chronic metabolic diseases. Metformin, a widely used antidiabetic drug, have been reported to act as an AMPK activator by inhibiting complex I of the mitochondrial electron transport chain in many tissues, including adipose, skeletal muscle, and heart. A recent small clinical trial observed that metformin administration did improve some of the metabolic profiles for glucocorticoid-treated patients with inflammatory disease but without pre-existing diabetes. In addition, another antidiabetic drug sodium-glucose-cotransporter-2 (SGLT-2) inhibitors can improve metabolic parameters and cardiovascular risk in patients with or without diabetes in preclinical and clinical studies. A small clinical trial reported that compared to metformin, significant improvement in anthropometric parameters and body composition, in overweight and obese women with polycystic ovary syndrome after 12 weeks of treatment with empagliflozin. Hence, metformin and SGLT2 agents may be used as potential adjuvant therapies to improve metabolic disorders after KT. However, both metformin and SGLT-2 inhibitors were not recommended in patients with impaired kidney function considering their elimination and action mechanism. Although several preliminary clinical trials showed that metformin and SGLT-2 inhibitors can be used safely and improve glucose control after KT, but they are small-sample sized and only include patients with diabetes. We will conduct a prospective clinical trial with the first aim of exploring the safety of metformin and SGLT-2 inhibitors in kidney transplant recipients with or without diabetes, and the second aim of exploring their roles in improving metabolic profiling.
The data will be obtained from 10 tertiary centers located in Poland (Cracow - coordinating center, Warsaw - 3 centers, Sosnowiec, Szczecin, Bydgoszcz, Lublin, Gdansk, Poznan) and 5 foreign centers. The analyses will include patients with rectal cancer operated on between 2013-2019. A database in MS Excel is prepared that consists of following data: - Type of neoadjuvant treatment (if any) - Time-interval between the end of neoadjuvant treatment and surgery - Type of surgery - Staging of rectal cancer i.e. (y)pTNM - Number of retrieved lymph nodes - Number of lymph nodes with metastases - R classification (R0, R1, R2) - Preoperative medications (metformin, statins, NSAIDs, anticoagulants) - Recurrence date and type (local, systemic, both diagnosed at the same time) - Date of death or date of last follow-up visit The aims of the study are following: 1. Establishing whether neoadjuvant treatment (PSCR or chemoradiotherapy) influences number of retrieved lymph nodes in rectal cancer 2. Establishing whether time-interval between the end of PSCR and surgery influences lymph node yield 3. Establishing the prognostic value of lymph node ratio - validation of the previously calculated cutoff point at the level of 0.41 4. Determining independent prognostic factors in rectal cancer - in particular related to medications taken before the operation, metformin and anti diabetic drugs in the first place
Most of the sporadic colorectal cancer (CRC )develop from colorectal adenoma (CRA), patients with CRA have a high risk of recurrence and development of metachronous CRA or CRC after removal, therefore, the investigators conducted this clinical trial to explore the chemoprevetion effect of metformin for CRA recurrence after removal.
This study is a randomized trial that evaluates the effect of metformin addition or not to standard care on the duration of diabetes remission after bariatric surgery.
To analyze the effects of altering the time of ingestion of participants' habitual medication (i.e., metformin, statins, ARAII/IACE) and meals around the time of exercise training (exercise fasted or fed) on the improvement of metabolic syndrome factors (hypertension, insulin sensitivity, dyslipidemia, and obesity). There will be a preliminary study of the effects of training "time-of-day" on the primary study outcomes.
This study aims to investigate the effect of metformin as host-directed therapy in obese/overweight patients with dengue Primary Objective To evaluate the safety and tolerability of metformin in obese/overweight young adults and children with dengue Secondary Objectives - To assess the effect of metformin therapy in obese/overweight patients with dengue on physiological, clinical and virological parameters - To assess the immunomodulation effects of metformin therapy in obese/overweight patients with dengue - To assess difference in gene expression between treatment group compared to non-treatment population
Evaluation of the effect of peri-operative continuation of oral metformin therapy on the incidence of perioperative hyperglycemia compared to standard preoperative cessation of oral metformin therapy 24h before surgery.
The investigators will evaluate the stool microbiota, serum and fecal bile acid composition, and changes in blood glucose and lipid profile before and after one month of metformin or YH1 treatment.
Berberine is an isoquinoline alkaloid extracted from medicinal herbs, has been demonstrated to produce beneficial effects on diabetes and hyperlipidemia, fewer study reported its modification on lipid metabolism in schizophrenia. Metformin, have been used for metabolic abnormalities in schizophrenia, findings from these studies indicated that they did have some effect,which are still in experimental stage.This study is aim to compare the efficacy and safety of berberine and metformin for preventing metabolic dysfunction in schizophrenia patients.
