Risk Factors Associated with Statin-Associated Muscle Symptoms in Patients Attending a Specialized Regional Lipid Clinic.

BACKGROUND: Statin-associated muscle symptoms (SAMS) are the major side effects reported for statins. Data from previous studies suggest that 7-29% of patients on statin had associated muscle symptoms. In the UK, there is a lack of corresponding data on SAMS and factors associated with the development of SAMS. OBJECTIVE: This analysis is aimed at establishing the prevalence of SAMS and identifying major contributory risk factors in patients attending a lipid clinic. METHODS: Clinical records of 535 consecutive patients, who visited the lipid clinic in the University Hospitals of Leicester, were studied retrospectively between 2009 and 2012. SAMS were defined by the presence of muscle symptoms with two or more different statins. Patients who reported muscle symptoms to statin with one or no rechallenge were excluded. The association of SAMS with clinical characteristics such as age and BMI, sex, smoking, excess alcohol, comorbidities, and medications was tested for statistical significance. A binomial logistic regression model was applied to adjust for risk factors significantly associated with SAMS. RESULTS: The prevalence of SAMS was found to be 11%. On unadjusted analysis, the mean age of patients who had SAMS was significantly higher than those without SAMS (59.4 ± 10.5 years vs. 50.3 ± 13.4 years, respectively, P < 0.001). Nonsmokers were more likely to develop SAMS in comparison to active smokers (P = 0.037). Patients taking antihypertensive medications were more likely to develop SAMS (P = 0.010). In binomial logistic regression analysis, only age was positively and significantly associated with SAMS after adjusting for other risk factors (ß = 0.054, P = 0.001). CONCLUSION: To the best of our knowledge, this study is the largest cohort of patients with SAMS in the United Kingdom. Our data suggest that the prevalence of SAMS is 11% and increased age is a risk factor associated with the development of SAMS in our cohort of patients.

Incentivizing Physician Diversity in Radiology.

In this article, the authors review the evolving state of diversity in the field of radiology. The authors discuss several early and recent historical legislative milestones that increased the equitable delivery of health care in the United States, such as Title VI of the Civil Rights Act of 1964, which ensured that funds for Medicare reimbursement would be available only to desegregated hospitals. Furthermore, the authors examine the current state of diversity and representation in radiology, in which underrepresented minorities represent 8.3% of training and practicing radiologists, and women represent 27.8% of radiologists. Finally, the authors present arguments for diversity in the current medical education system, analyze hurdles to increasing representation in radiology, and consider the future of diversity and inclusiveness in the field.

Emotional intimacy predicts condom use: findings in a group at high sexually transmitted disease risk.

Previous studies have reported an inverse relationship between condom use and emotional intimacy. The aim of this study was to determine the relationship between condom use and emotional intimacy. The study was a gonorrhoea case-comparison study with the samples being drawn from public health clinics (cases) and select bars/nightclubs (places) of Houston, TX (n = 215). Data were collected by questionnaires administered on a laptop computer. The majority of respondents were African-American (97.7%), women (69.3%) and had either high school or GED education (72.6%). Condom use with the last sexual partner was analysed along with intimacy with that partner assessed on a 3-point scale. Analysis showed that higher intimacy was related to greater condom use which was significant in men but not in women. In conclusion, these data were opposite to those of previous studies, which showed an inverse relationship between condom use and emotional intimacy. We hypothesize that in a high-risk environment, people exert more effort in protecting those they feel closer to. These data suggest a need to further explore the complex relationship between emotional intimacy and condom use.

Beneficial effects of clonidine in streptozotocin-induced diabetes and DOCA-hypertensive rats.

This investigation was undertaken to study the effects of chronic treatment with clonidine on cardiovascular complications in streptozotocin-induced diabetes and DOCA-hypertensive rats. Injection of streptozotocin induced glucosuria, hyperglycaemia, hypoinsulinaemia, hypothyroidism, hypercholesterolaemia, hypertriglyceridaemia, bradycardia and a decrease in left ventricular developed pressure (LVDP). DOCA by itself did not induce any change in blood-glucose levels in non-diabetic animals. However, in diabetic animals DOCA significantly reduced blood-glucose levels. Treatment of diabetic and diabetic hypertensive animals with clonidine (25 micrograms kg-1 every day for six weeks) significantly prevented diabetes-induced loss of body weight, bradycardia, cardiac hypertrophy and hypothyroidism. It also partially, but significantly, prevented diabetes-induced hyperglycaemia and hypoinsulinaemia in both diabetic and diabetic-hypertensive animals. There was a significant reduction in diabetes-induced elevation of cholesterol and triglyceride levels and an improvement in LVDP at higher filling pressure in diabetic and diabetic hypertensive animals. This investigation shows that chronic treatment with clonidine produces a number of beneficial effects such as prevention of hyperlipidaemia and hypothyroidism and improvement in cardiomyopathy and glycaemic control in diabetic and diabetic hypertensive rats.
