Malnutrition in obesity before and after bariatric surgery.

Bariatric surgeries are considered the only effective way of weight loss therapy in morbidly obese patients, i.e. body mass index ≥ 35. However, micronutrient deficiencies and malnutrition are common after most bariatric procedures and thus, pre- and postoperative nutritional assessment and corrections are advised. The present review is presented in an effort to describe in some detail about prevalence, and mechanisms of macro- and micronutrient deficiencies in obese and post-bariatric surgery individuals. We also aimed to summarize the data on screening and supplementation of macro- and micronutrients before and after bariatric surgeries.

Renal Transplantation after Transcatheter Aortic Valve Replacement: Case Report.

Patients with chronic kidney disease (CKD) have an increased likelihood of developing calcific aortic stenosis (AS). These patients also often suffer from multiple comorbidities, potentially making them high-risk surgical candidates and limiting their treatment options. Transcatheter aortic valve replacement (TAVR) is the recommended therapeutic approach for severe AS in patients who are not suitable candidates for surgical aortic valve replacement (SAVR). TAVR is being increasingly considered as a viable alternative to SAVR. As such, its applications in patients with CKD and other chronic diseases, as well as methods to optimize peri- and postoperative results are of great interest and significance. We present the case of a successful renal transplant procedure, performed within a year following a TAVR, in a 52-year-old man who suffered from multiple comorbidities.
