Novel anti-glycemic drugs and reduction of cardiovascular risk in diabetes: expectations realized, promises unmet.
The researchers review evidence on cardiovascular risks and benefits of new treatments for type 2 diabetes mellitus. Their review reports new evidence suggesting that the newest diabetes drugs are safe from a cardiovascular perspective. Evidence on benefit from at least some members of the GLP-1 receptor agonist and SGLT-2 inhibitor classes is encouraging but not yet decisive.

Pharmacologic and non-pharmacologic treatments for chronic pain in individuals with HIV: a systematic review.
The authors conducted a systematic review to identify clinical trials and observational studies examining the impact of pharmacologic or non-pharmacologic interventions on pain and/or functional outcomes among HIV-infected individuals with chronic pain in high-development countries. They found that the only included controlled studies with positive results were of capsaicin and cannabis. Among the seven studies of pharmacologic interventions, the authors determined that five had substantial pharmaceutical industry sponsorship. Their findings highlight several important gaps in the HIV/chronic pain literature requiring further research.

The effect of substance use disorders on the association between guideline-concordant long-term opioid therapy and all-cause mortality.
The objective of this study was to determine whether the presence of a substance use disorder (SUD) modifies the association between guideline-concordant care and 1-year all-cause mortality among patients receiving long-term opioid therapy (LtOT) for pain. It found that for clinicians prescribing LtOT to patients with untreated SUDs, engaging patients with psychotherapeutic and SUD treatment services may reduce mortality.

Association between breast cancer recurrence and immunosuppression in rheumatoid arthritis and inflammatory bowel disease: a cohort study.
The researchers examined the rates of breast cancer recurrence in patients with immune-mediated disease and treated breast cancer who received therapy with methotrexate, thiopurines, or anti-tumor necrosis factor (anti-TNF). They found that the risk of breast cancer recurrence in patients who received methotrexate, thiopurine, or anti-TNF therapy was not statistically significantly increased, although they did not rule out a 2-fold or greater increased risk in those treated with thiopurines.

The effectiveness of pharmacist-provided telephonic medication therapy management on emergency department utilization in home health patients.
This article's objective is to evaluate the effectiveness of a telephonic medication therapy management (MTM) service on reducing emergency department utilization within a Medicare-insured home health population. The authors found that this pharmacist-delivered telephonic medication therapy management program did not decrease emergency department utilization overall but may further reduce the such risk among patients who are at lower risk of utilization.

Use of heart failure medical therapies among patients with left ventricular assist devices: insights from INTERMACS.
The authors examined the use of heart failure medications before and after left ventricular assist devices (LVAD) implant in adult patients enrolled in the Interagency Registry for Mechanically Assisted Circulatory Support (INTERMACS). They found that overall use of neurohormonal antagonists was low after LVAD implant, whereas use of loop diuretics and amiodarone remained high, and concluded that heart failure medication use is highly variable, but appears to generally increase after LVAD implantation.

Calcineurin inhibitor minimization, conversion, withdrawal, and avoidance strategies in renal transplantation: a systematic review and meta-analysis.
The researchers evaluated 92 comparisons from 88 randomized controlled trials and found moderate- to high-strength evidence suggesting that minimization strategies result in better clinical outcomes compared with standard-dose regimens and moderate-strength evidence indicating that conversion to a mammalian target of rapamycin inhibitor or belatacept was associated with improved renal function but increased rejection risk.

Medication adherence may be more important than other behaviours for optimizing glycaemic control among low-income adults.
The authors sought to identify which behaviors are most important for HbA1c among low-socioeconomic status patients with type 2 diabetes mellitus. They found that only medication adherence was significantly associated with lower HbA1c after adjusting for the other self-care behaviours and further adjusting for demographic and diabetes characteristics. They suggested that focused efforts to improve medication adherence among low-socioeconomic status patient populations may improve glycemic control.

Risk of suicidal events with atomoxetine compared to stimulant treatment: a cohort study.
The researchers analyzed whether the observed increased risk of suicidal ideation in clinical trials translates into an increased risk of suicidal events in pediatric patients treated with atomoxetine compared with stimulants in 26 Medicaid programs. They found that first- and second-line treatment of youths age 5 to 18 with atomoxetine compared with stimulants was not significantly associated with an increased risk of suicidal events.

Barriers to adoption of mineralocorticoid receptor antagonists in patients with heart failure: A mixed-methods study.
Mineralocorticoid receptor antagonists (MRAs) are the most underutilized pharmacotherapy for heart failure. This study sought to ascertain barriers to optimal use of MRAs. It identified eight primary barriers to MRA adoption at the provider, patient, and health system levels from the prescriber perspective. These barriers can inform the creation of multilevel interventions that will be required to close the gap in MRA adoption.

Cardiovascular effects of androgen deprivation therapy for the treatment of prostate cancer: ABCDE steps to reduce cardiovascular disease in patients with prostate cancer.
Since cardiovascular disease risk may be increased by the use of androgen deprivation therapy (ADT), the researchers have adapted the five-step "ABCDE" algorithm for prostate cancer survivors. Its treatment recommendations come under the following headings: awareness and aspirin, blood pressure, cholesterol and cigarettes, diet and diabetes, and exercise. The algorithm is illustrated by a hypothetical case study.

Effectiveness and safety of aldosterone antagonist therapy use among older patients with reduced ejection fraction after acute myocardial infarction.
The purpose of this paper is to describe how aldosterone antagonist treatment is used among older myocardial infarction (MI) patients in routine practice. They found that aldosterone antagonist use was not associated with lower mortality except in symptomatic HF patients, and risks of hyperkalemia were low at 30 days, but significantly higher among patients prescribed aldosterone antagonists, as was risk of acute renal failure compared with patients not prescribed aldosterone antagonists. They concluded that these results underscore the importance of close post-discharge monitoring of this patient population.

Systematic review: monotherapy with antitumour necrosis factor alpha agents versus combination therapy with an immunosuppressive for IBD.
The authors discussed the efficacy and the risks of anti-TNF monotherapy versus combination therapy with an immunosuppressive in patients with IBD. They concluded that the addition of an immunosuppressive to anti-TNF therapy improves treatment efficacy for infliximab in ulcerative colitis and Crohn’s disease. Further, the use of combination therapy appears to add no significant incremental risk for serious infections above that seen with anti-TNF or immunosuppressive monotherapy in most patients.

Increasing utilization and predictors of hematopoietic growth factors in patients diagnosed with colorectal cancer: findings from a large national population-based cohort in the USA, 1992-2009.
The authors examined the temporal trend and predictors of receiving hematopoietic growth factors in a large nationwide and population-based cohort of patients with colorectal cancer in the USA from 1992 to 2009. They found that gender, marital status, comorbidity scores, geographic area, year of diagnosis, tumor stage, number of lymph nodes, and risk profile for febrile neutropenia were statistically significant predictors of using colony-stimulating factors and erythropoiesis-stimulating agents.

Recent trends in medication usage for the treatment of juvenile idiopathic arthritis and the influence of tumor necrosis factor inhibitors.
The researchers investigated temporal trends in medication use among children diagnosed with juvenile idiopathic arthritis (JIA). They found that the use of tumor necrosis factor inhibitors (TNFi) in the treatment of JIA increased 2- to 3-fold from 2005 to 2012. New TNFi use was associated with decreased NSAID and oral glucocorticoids use. TNFi may be replacing, rather than complementing, methotrexate in the treatment of many patients.

Physician practices regarding contraindications to oral anticoagulation in atrial fibrillation: findings from the Outcomes Registry for Better Informed Treatment of Atrial Fibrillation (ORBIT-AF) registry.
This study describes the frequencies of and factors associated with oral anticoagulation (OAC) contraindications in clinical practice for patients with atrial fibrillation (AF). Contraindications to OAC therapy among patients with AF are common but subjective. Many patients with reported contraindications were receiving OAC, suggesting that the perceived benefits outweighed the potential harm posed by the relative contraindication.
