BACKGROUND: Regular aspirin use is associated with reduced risk of several malignancies. Epidemiologic studies analyzing aspirin, nonaspirin nonsteroidal anti-inflammatory drug (NSAID), and acetaminophen use and ovarian cancer risk have been inconclusive.

METHODS: We analyzed pooled data from 12 population-based case-control studies of ovarian cancer, including 7776 case patients and 11843 control subjects accrued between 1992 and 2007. Odds ratios (ORs) for associations of medication use with invasive epithelial ovarian cancer were estimated in individual studies using logistic regression and combined using random effects meta-analysis. Associations between frequency, dose, and duration of analgesic use and risk of ovarian cancer were also assessed. All statistical tests were two-sided.

RESULTS: Aspirin use was associated with a reduced risk of ovarian cancer (OR = 0.91; 95% confidence interval [CI] = 0.84 to 0.99). Results were similar but not statistically significant for nonaspirin NSAIDs, and there was no association with acetaminophen. In seven studies with frequency data, the reduced risk was strongest among daily aspirin users (OR = 0.80; 95% CI = 0.67 to 0.96). In three studies with dose information, the reduced risk was strongest among users of low dose (<100 mg) aspirin (OR = 0.66; 95% CI = 0.53 to 0.83), whereas for nonaspirin NSAIDs, the reduced risk was strongest for high dose (≥500 mg) usage (OR = 0.76; 95% CI = 0.64 to 0.91).

CONCLUSIONS: Aspirin use was associated with a reduced risk of ovarian cancer, especially among daily users of low-dose aspirin. These findings suggest that the same aspirin regimen proven to protect against cardiovascular events and several cancers could reduce the risk of ovarian cancer 20% to 34% depending on frequency and dose of use.

Pharmacists are key partners in antimicrobial stewardship efforts, yet their degree of education on and attitudes toward this topic during training are not well documented. An electronic survey measuring knowledge and attitudes regarding antimicrobial use and resistance was administered to graduating pharmacy students at 12 US schools of pharmacy. Of 1445 pharmacy students, 579 (40%) completed the survey. The vast majority (94%) believed that strong knowledge of antimicrobials was important for their pharmacy careers, and 89% desired more education on appropriate antimicrobial use. Most students (84%) considered their pharmacy education regarding antimicrobials useful or very useful, but there was significant variability on perceptions of preparation for most antimicrobial stewardship activities according to the students' school. The mean number of correct answers on a section of 11 knowledge questions was 5.8 (standard deviation 2.0; P value for score between schools <.001). On multivariable linear regression analysis, significant predictors of a higher knowledge score were pharmacy school attended, planned postgraduate training, completion of a clinical rotation in infectious diseases, perception of pharmacy school education as useful, use of resources to answer the knowledge questions, and use of Infectious Diseases Society of America guidelines and smartphone applications as frequent resources for learning about antimicrobials. Pharmacy students perceive antimicrobial stewardship to be an important healthcare issue and desire more education on the subject. Student perceptions of antimicrobial coursework and actual antimicrobial knowledge scores significantly varied by the school of pharmacy attended. Sharing of best practices among institutions may enhance the preparation of future pharmacists to contribute to effective antimicrobial stewardship.

Objective. The purpose of this study was to evaluate glycemic control as measured by A1C during a 2-year period after patients received diabetes self-management education (DSME). Methods. Patients who completed DSME in 2009 and received medical follow-up with A1C measurements for at least 2 years after DSME were included in the evaluation. Primary endpoints were changes in A1C from before to immediately after, 1 year after, and 2 years after DSME. Secondary outcomes included the effects of the following factors on change in A1C: sex, duration of diabetes, uncontrolled diabetes (A1C ≥ 9%), health insurance coverage, and self-reported education level. Results. Forty-three patients were included in the evaluation. Mean A1C before DSME was 10.2 ± 3.7%. Mean A1C after DSME was 7.8 ± 2.2% (P < 0.0001), a 23.5% reduction. Mean A1C at 1 and 2 years after DSME was 7.8 ± 2.1% for each year and remained unchanged from just after DSME to 1 and 2 years after DSME (P > 0.05). Patients with a duration of diabetes of < 1 year had a significantly greater reduction in mean A1C than those with a duration of diabetes ≥ 1 year (28.7 and 20.2%, respectively, P = 0.001). Conclusion. DSME improved glycemic control to a substantial degree, and the effect was sustained for up to 2 years. Although the reduction in A1C was significant for all patients receiving DSME, there was a significantly greater reduction for patients who had a duration of diabetes of < 1 year than for those with a duration of diabetes > 1 year.

CASE (DESCRIPTION): This report describes an incident of limb swelling after revaccination with the 23-valent pneumococcal polysaccharide vaccine (PPSV23). A 5-year old female with sickle cell disease experienced severe arm swelling with edema to the extent that it was difficult to put a shirt over the arm. The day prior, she received PPSV23 concomitantly with the meningococcal vaccine. She had received the PPSV23 vaccine 2.5 years prior to the event. The patient was managed with analgesics, antiemetics, and antibiotic prophylaxis and the arm swelling resolved 24 h later. A decreased length of time between revaccination and concurrent administration with the meningococcal vaccine could have contributed.

CONCLUSION: Although rare, limb swelling after revaccination could be a concern in special at-risk populations where repeated vaccination is necessary for pneumococcal protection.

OBJECTIVE To report an atypical case of Guillain-Barré syndrome (GBS) after administration of the 2012-13 influenza vaccine. SETTING Urban tertiary hospital. PATIENT DESCRIPTION An 81-year-old man was admitted to the hospital after he began experiencing numbness and tingling in both feet that began ascending toward the waistline. The patient complained of intense neuropathic pain in his lower extremities and eventually lost the deep tendon reflexes in his ankles. CASE SUMMARY In addition to clinical manifestations of GBS, electromyography revealed a sensorimotor, polyneuropathy, predominantly axonal, with prolonged F-waves in all nerves tested. A lumbar puncture revealed clear and colorless cerebrospinal fluid with an elevated protein level of 66 mg/dL (reference, 15-60 mg/dL) despite the lack of a normal cell count, which indicates albuminocytologic dissociation. Based on these findings, the patient met Brighton level 3 diagnostic certainty and was diagnosed with GBS. MAIN OUTCOMES MEASURE Signs and symptoms of GBS. RESULTS On day 5 of hospitalization, intravenous immunoglobulin 0.4 mg/kg/d was initiated for 5 days in combination with gabapentin 100 mg at bedtime for neuropathic pain. After completing treatment, the patient experienced progressively improved sensation in his extremities and was discharged. CONCLUSION This is a rare report of GBS lacking albuminocytologic dissociation after an older patient received the 2012-13 influenza vaccine.
