Poor adherence to treatment may contribute to the treatment gap in chronic obstructive pulmonary diseases (COPD). The aim of the current study was to describe the association between adherence to treatment and the risk of COPD moderate (ME) and severe (SE) exacerbations, and health care utilization. ⋯ Despite the typical limitations of an administrative database study, the results of this large population-based study have shown that reduced adherence to treatment with TIO and FSC is associated with increased risk for exacerbations and higher health care utilization in COPD patients.

Alpha2-adrenoceptor (α2 AR) antagonists inhibit the growth of breast cancer cells. The action of beta2-adrenoceptors (β2 AR) on cell proliferation is still controversial. In this study, we investigated the association of α2a and β2 AR expression with tumor-relevant biological markers and clinical outcome. ⋯ In hormone receptor positive breast cancer patients, strong β2 AR expression is correlated with better DFS than weak β2 AR expression and an interaction may exist between β2 AR and hormone receptor pathways. Some limitations of this study were the relatively small sample size and the intrinsic nature of retrospective study per se. Findings of the study are for hypothesis only and need to be confirmed in large prospective studies.

Adherence with oral tyrosine kinase inhibitor (TKI) therapy over prolonged timeframes is required for successful outcomes among patients with chronic phase chronic myelogenous leukemia (CP-CML). Since quantitative polymerase chain reaction (qPCR) monitoring may identify early suboptimal responses, and thereby permit detection of non-adherence to therapy, we sought to assess the association between frequency of molecular monitoring and medication adherence. ⋯ Frequent molecular monitoring (3-4 times per year as recommended in current guidelines) is associated with greater TKI treatment adherence for patients diagnosed with CML. Since TKI adherence >80% has been associated with better clinical outcomes, this study underscores the importance of molecular monitoring.
