Randomized Controlled TrialEfficacy of multivitamin supplementation containing vitamins B6 and B12 and folic acid as adjunctive treatment with a cholinesterase inhibitor in Alzheimer's disease: a 26-week, randomized, double-blind, placebo-controlled study in Taiwanese patients.
Elevated serum homocysteine levels have been associated with the development of Alzheimer's dementia (AD). The combined use of a mecobalamin capsule preparation, which contains vitamin B12 0.5 mg with an active methyl base, and an over-the-counter nutritional supplement that contains folic acid 1 mg and pyridoxine hyperchloride 5 mg may be effective as a homocysteine-lowering vitamin regimen. ⋯ In this population of patients with mild to moderate AD in Taiwan, a multivitamin supplement containing vitamins B(6) and B(12) and folic acid for 26 weeks decreased homocysteine concentrations. No statistically significant beneficial effects on cognition or ADL function were found between multivitamin and placebo at 26 weeks.

Comparative StudyCost-effectiveness analysis of bevacizumab combined with chemotherapy for the treatment of metastatic colorectal cancer in Japan.
Rapid progress has been made in the treatment of metastatic colorectal cancer (mCRC). New treatment regimens for mCRC include not only cytotoxic chemotherapy but also targeted monoclonal antibodies, including bevacizumab. However, bevacizumab is an expensive medication, which costs from 300,000 yen to 400,000 yen (US $2500-$3300) per month. ⋯ In this cost-effectiveness analysis in Japan, the ICERs of bevacizumab + FU/LV combination treatment, IFL, and second-line FOLFOX4 were high compared with other chemotherapies for mCRC. It remains difficult to assess first-line therapies comprising bevacizumab with oxaliplatin-based regimens, especially CAPOX. Further information is needed to assess cost-effectiveness.

Abuse potential of carisoprodol: a retrospective review of Idaho Medicaid pharmacy and medical claims data.
Carisoprodol is a muscle relaxant indicated as adjunctive therapy in acute, painful musculoskeletal conditions. Case reports of drug-seeking behavior and utilization of carisoprodol in combination with opioids have suggested abuse potential. ⋯ The results from this review suggest that, compared with long-term users of other SMRs, carisoprodol patients utilized concomitant opioids more frequently and concomitant NSAIDs less frequently, more commonly had past diagnoses indicating other drug dependence or abuse, and continued to pay out of pocket for carisoprodol when third-party coverage was discontinued. While none of these issues alone may be direct indicators of abuse, collectively they suggest that patients who used carisoprodol long term displayed abuse potential characteristics more frequently than long-term users of other agents.

Oseltamivir and the risk of influenza-related complications and hospitalizations in patients with diabetes.
This subgroup analysis of a retrospective cohort study examined, from a managed care perspective, the risk of influenza-related complications and hospitalizations in patients with diabetes who were prescribed oseltamivir for the treatment of influenza and those who were not prescribed antiviral treatment. ⋯ In this retrospective study, the risk of influenza-associated respiratory illnesses and the number of hospitalizations for any reason were reduced in patients with diabetes who were prescribed oseltamivir compared with an unmatched group that was not prescribed antiviral therapy.
