Sunitinib is an inhibitor of the vascular endothelial growth factor and platelet-derived growth factor receptors, and it has antitumor activity in metastatic renal cell carcinoma and gastrointestinal stromal tumors. To further investigate the fatigue associated with sunitinib therapy, thyroid function tests were performed on patients with metastatic renal cell carcinoma who were receiving sunitinib. Seventy-three patients with metastatic renal cell carcinoma were treated with sunitinib at the Cleveland Clinic Taussig Cancer Center, and 66 of them had thyroid function test results available. Fifty-six (85%) of the 66 patients had one or more abnormality in their thyroid function test results, consistent with hypothyroidism, and 47 (84%) of the 56 patients with abnormal thyroid function tests had signs and/or symptoms possibly related to hypothyroidism. Thyroid hormone replacement was undertaken in 17 patients, and symptoms improved in nine of them. Thyroid function test abnormalities appear to be common in patients with metastatic renal cell carcinoma treated with sunitinib, and routine monitoring is warranted.
Pain is one of the most common symptoms in cancer patients. Opioids are widely prescribed for this and other purposes. Properly used, they are safe, but they have serious and potentially lethal side effects. Successful use of opioids to manage cancer pain requires adequate knowledge about opioid pharmacology and equianalgesia for the purpose of both drug rotation and route conversion. The aim of this study was to demonstrate variations in equianalgesic ratios, as quoted in equianalgesic tables and various educational materials widely available to practicing physicians. We surveyed commercially available educational materials in package inserts, teaching materials provided by pharmaceutical companies, and the Physicians' Desk Reference for equianalgesic tables of commonly used opioids. We found inconsistent and variable equianalgesic ratios recommended for both opioid rotation and conversion. Multiple factors like inter- and intraindividual differences in opioid pharmacology may influence the accuracy of dose calculations, as does the heterogeneity of study design used to derive equianalgesic ratios. Equianalgesic tables should only serve as a general guideline to estimate equivalent opioid doses. Clinical judgment should be used and individual patient characteristics considered when applying any table. Professional organizations and regulators should establish a rotation and conversion consensus concerning opioid equianalgesic ratios. Systematic research on equianalgesic opioid dose calculation is recommended to avoid adverse public health consequences of incorrect or inappropriate dosing. Current information in equianalgesic tables is confusing for physicians, and dangerous to the public.
Objectives: To describe long‐term food availability and prices from 1961 to 2007 and body mass index (BMI) trends from 1980 to 2010 in Samoa, and to contextualize these trends within political, economic, cultural, behavioral, and climatic influences. Methods: National level data on food availability and pricing were obtained from the open access database FAO (http://faostat.fao.org). Data for Samoa were collected from annual food balance sheets available for the period 1961–2007. Mean BMI for Samoan men and women aged 35–44 years of age is reported from four different time periods, 1979–1982, 1991, 2003, and 2010. Results: Total energy availability increased substantially, by 47%, with more than 900 extra calories available per capita per day in 2007 than in 1961. Many of these extra calories are supplied by dietary fat, the availability of which rose by a proportionally greater amount, 73%. Availability of both meat and vegetable oils rose substantially. Poultry meat increased the most proportionally, from 10 to 117 kcal per capita per day. Coconut products, fruits, and starchy root crops—all locally grown—showed little to no increase over this time. As import prices for poultry and mutton increased their availability decreased, but the availability of vegetable oils rose despite a rise in their price. Mean BMI for men and women aged 35–44 years rose 18% rise from 1980 to 2010. Conclusions: These long‐term trends in food availability and prices, and the temporal pattern of BMI provide national level data for understanding the process of the nutritional transition in Samoa. Further work on consumer food prices, diet, food security, and health is needed to further contextualize the transformation of the local food system in Samoa. Samoa. Am. J. Hum.

Opioid prescribing errors were common. Females may be at greater risk of multiple errors. A PM consultation program is effective in identifying and correcting a wide variety of opioid prescribing errors.
Seventeen patients with locally advanced or metastatic renal cell carcinoma (RCC) were enrolled in this phase II trial. The purpose of the trial was to assess the efficacy of the administration of oral GD0039, and to further assess the pharmacokinetics and pharmacodynamics of this drug. Patients were given an initial dose of 37.5 micro g/kg b.i.d for 3 weeks followed by one week off in each cycle, with the treatment continuing until disease progression or adverse effects. All 17 patients discontinued treatment due to disease progression or toxicity. Adverse events such as fatigue, nausea and diarrhea were common but generally mild. No evidence of anti-tumor activity of GD0039 was seen in this study.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
