Heterogeneity of weight loss after gastric bypass,sleeve gastrectomy,and adjustable gastric banding

Background

Laparoscopic Roux-en-Y gastric bypass, laparoscopic sleeve gastrectomy, and laparoscopic adjustable gastric banding all lead to substantial weight loss in obese patients. Long-term weight loss can be highly variable beyond 1-year postsurgery. This study examines and compares the frequency distribution of weight loss and lack of treatment effect rates after laparoscopic Roux-en-Y gastric bypass, laparoscopic sleeve gastrectomy, and laparoscopic adjustable gastric banding.

Premature Ticagrelor Discontinuation in Secondary Prevention of Atherosclerotic CVD: JACC Review Topic of the Week

Ticagrelor is a cornerstone of modern antithrombotic therapy alongside aspirin in patients with acute coronary syndrome and after percutaneous coronary intervention. Adverse effects such as bleeding and dyspnea have been associated with premature ticagrelor discontinuation, which may limit any potential advantage of ticagrelor over clopidogrel. The randomized trials of ticagrelor captured adverse events, offering the opportunity to more precisely quantify these effects across studies. Therefore, a meta-analysis of 4 randomized clinical trials of ticagrelor conducted between January 2007 and June 2017 was performed to quantify the incidence and causes of premature ticagrelor discontinuation. Among 66,870 patients followed for a median 18 months, premature ticagrelor discontinuation was seen in 25%; bleeding was the most common cause of discontinuation followed by dyspnea. Versus the comparators, the relative risk of dyspnea-related discontinuation during follow-up was 6.4-fold higher, the relative risk of bleeding was 3.2-fold higher, and the relative risk of discontinuation due to any adverse event was 59% higher for patients receiving ticagrelor. Understanding these potential barriers to adherence to ticagrelor is crucial for informed patient-physician decision making and can inform future efforts to improve ticagrelor adherence. This review discusses the incidence, causes, and biological mechanisms of ticagrelor-related adverse effects and offers strategies to improve adherence to ticagrelor.     

Giant mediastinal liposarcoma: a case report.

Liposarcomas are extremely rare in the mediastinum. They may achieve considerable size before causing any symptoms. Mediastinal liposarcomas may invade surrounding structures like the pericardium or the superior vena cava. Complete surgical excision is the optimal treatment in resectable cases. Excision of adjacent structures like the pericardium may be needed if the tumor infiltrates them. We report on a case of a giant liposarcoma of the mediastinum involving both hemithoraces and extending into the neck, which was successfully managed by complete surgical excision.     

Comparison of TURP, TUVRP, and HoLEP

Since the first transurethral resection of the prostate (TURP) was performed by Guyon at the Necker Hospital in Paris in 1901, this treatment modality has replaced open prostatectomy as the procedure of choice for more than 95% of patients. TURP has been used in surgical treatment of benign prostatic hyperplasia (BPH) and remains the gold standard treatment. Transurethral vapor resection of the prostate (TUVRP) and holmium laser enucleation of the prostate (HoLEP) are new treatment modalities for the treatment of BPH. Each procedure has its own advantages and disadvantages. Availability of instruments, surgical expertise, and specific indications for a particular procedure are of utmost importance for successful outcome, with minimal morbidity. TURP can be either monopolar or bipolar, using thin or thick loop. Bipolar TURP is associated with less bleeding and less chances of dilutional hyponatremia. TUVRP, using a thick wedge loop, causes vaporization and resection of the prostate, and is associated with less bleeding and short operative time. HoLEP is another effective alternative for the surgical treatment of BPH. The holmium laser possesses the ideal combination of cutting and coagulation; however, it has a learning curve.     

Goldenhar’s Syndrome associated with congenital cyanotic heart disease

A case of Goldenhar’s Syndrome in a 10 year old girl is reported. The unusual features are the absence of epibulbar dermoid which is one of the major hallmarks of the Syndrome and the presence of an associated Cyanotic Heart disease.     

Pharmacological Studies on Leaves of Withania somnifera.

Anti-inflammatory activity and protective effect against CCl (4)-induced hepatotoxicity of alcoholic extract of leaves of WITHANIA SOMNIFERA have been assessed. The leaves were found to possess marked effects in subacute inflammation and hepatotoxicity. A comparison of the anti-inflammatory properties revealed the extract at 1 g/kg dose to be as active as 50 mg/kg of phenylbutazone and 10 mg/kg of hydrocortisone. The protective effect of the extract at 1 g/kg dose against CCl (4)-induced hepatotoxicity was comparable to 10 mg/kg of hydrocortisone.
