Antacid Therapy

Forty-four patients with symptoms of gastro-oesophageal reflux were randomly assigned in a crossover trial to treatment for 15-day periods with Liquid Gaviscon (a reflux suppressant) or an antacid gel containing magnesium and aluminium hydroxide. Good relief of symptoms was reported by 84% of patients during therapy with Liquid Gaviscon compared to only 23% during antacid therapy. Relief of symptoms was obtained within 15 minutes by 68% of patients during therapy with Liquid Gaviscon compared to only 9% during antacid treatment. The beneficial effect lasted for more than 4 hours in 75% of patients during treatment with Liquid Gaviscon compared to only 23% of patients obtaining long-term relief during antacid therapy.

Painless Jaundice

AbstractPainless jaundice is a harbinger of malignant biliary obstruction, with the majority of cases due to pancreatic adenocarcinoma. Despite advances in treatment, including improved surgical techniques and neoadjuvant (preoperative) chemotherapy, long-term survival from pancreatic cancer is rare. This lack of significant improvement in outcomes is believed to be due to multiple reasons, including the advanced stage at diagnosis and lack of an adequate biomarker for screening and early detection, prior to the onset of jaundice or epigastric pain. Close attention is required to select appropriate patients for preoperative biliary decompression, and to prevent morbid complications from biliary drainage procedures, such as pancreatitis and cholangitis. Use of small caliber plastic biliary stents during endoscopic retrograde cholangiopancreatography should be minimized, as metal stents have increased area for improved bile flow and a reduced risk of adverse events during neoadjuvant therapy. Efforts are underway by translational scientists, radiologists, oncologists, surgeons, and gastroenterologists to augment lifespan for our patients and to more readily treat this deadly disease. In this review, the authors discuss the rationale and techniques of endoscopic biliary intervention, mainly focusing on malignant biliary obstruction by pancreatic cancer.

Statin Use

In this single center, retrospective cohort study we wished to compare early and total mortality for all patients treated for abdominal aortic aneurysms (AAA) with open surgery who were taking statins compared to those who were not. A cohort of 640 patients with AAA was treated with open surgery between 1999 and 2012. Patients were consecutively recruited from a source population of 390,000; 21.3% were female, and the median age was 73 years. The median follow-up was 3.93 years, with an interquartile range of 1.79–6.58 years. The total follow-up was 2855 patient-years. An explanatory strategy was used. The propensity score (PS) was implemented to control for selection bias and confounders. The crude effect of statin use showed a 78% reduction of the 30-day mortality. A stratified analysis using the Mantel–Haenszel method on quintiles of the PS gave an adjusted effect of the odds ratio equal to 0.43 (95% CI: 0.18–0.96), indicating a 57% reduction of the 30-day mortality for statin users. The adjusted rate ratio was 0.62 (95% CI: 0.45–0.83), indicating a reduction of long-term mortality of 38% for statin users compared to non-users for a median follow-up of 3.93 years. This retrospective cohort study showed a significant beneficial effect of statin use on early and long-term survival for patients treated with open surgery. To be conclusive, our results need to be replicated by a randomized clinical trial.

Long term preservation of mouse sperm in a desiccated state using sugars like trehalose may offer attractive economic benefits in the management of rapidly increasing transgenic mouse strains. The goal of the current study was to evaluate the protective effect of intracellular trehalose on sperm nucleus by predicting the long-term nuclear degradation kinetics of desiccated spermatozoa using an Arrhenius model whose parameters are obtained from high temperature-short time storage studies. B6D2F1 sperm isolated in an EGTA supplemented tris-HCl buffer (with or without 0.5M intracellular trehalose) were convectively dried with inert nitrogen gas in a controlled manner to moisture content >5%. The samples were then vacuum packed and stored at 22, 37, 45, 60 and 90°C for 1, 3 or 7 days. Following rehydration, the sperm sample was assayed for DNA damage using the sperm chromatin structure assay (SCSA). Results indicate significantly (p>0.05) lower DNA degradation for cells dried with intracellular trehalose at 45, 60 and 90°C for 1, 3 or 7 days compared to cells dried without trehalose. Based on a 10% increase in the index of injury, the calculated activation energy and frequency factors were 10.33 kcal/mole and 5.4×105 hr−1 respectively for cells dried in EGTA solution only. The corresponding numbers for cells dried in EGTA solution supplemented with 0.5M trehalose were 5.7 kcal/mole and 43.73 hr−1. Based on these parameters the time required for 10% DNA degradation are 279 and 759 hours for samples desiccated in plain EGTA vs. trehalose supplemented EGTA. These results indicate the beneficial effect of intracellular trehalose for the long-term storage of desiccated sperm.
