Objective: To evaluate the mid-long-term efficacy and safety of the dexamethasone intravitreal (DEX) implant (Ozurdex1) in naïve patients with diabetic macular edema (DME). Methods: Prospective and single-center study conducted on consecutive patients with a diagnosis of DME, who received a DEX implant and were followed up for at least 12 months. The main outcomes measurements were the mean change in best corrected visual acuity (BCVA) and in foveal thickness (FT) as compared to the baseline values. ⋯ During the study follow-up, the patients receive a mean of 3.4 (2.9-3.9) implants. Of the 32 phakic eyes at baseline, 17 (53.1%) either developed new lens opacity or progression of an existing opacity. Conclusion: In eyes with DME not previously treated with intravitreal drugs, DEX implants provide meaningful functional and anatomical benefits, and these results are sustained mid-long-term.

Background: Although atrial fibrillation (AF) and coronary artery disease (CAD) are increasing in prevalence in Japan, real-world data regarding clinical outcomes in Japanese AF patients with CAD are limited. Methods: The SAKURA AF Registry is a prospective multi-center registry created to investigate outcomes of oral anticoagulant (OAC) use in Japanese AF patients. A study was conducted involving 3237 enrollees from 63 Tokyo-area institutions who were followed up for a median of 39.3 months. ⋯ Conclusions: CAD did not appear to be a major determinant of strokes/TIAs, major bleeding, or all-cause mortality, but appeared to increase the risk of cardiovascular events in Japanese AF patients. The risk of major bleeding in CAD patients appeared to decrease when a DOAC rather than warfarin was administered. The data suggested that patients with AF and concomitant CAD require careful management and follow-up to reduce cardiovascular risks, and DOACs may be a better choice over warfarin when considering the risk of major bleeding.

Randomized Controlled Trial
Bronchodilator efficacy of tiotropium/formoterol (18/12 µg once daily via a Discair inhaler), tiotropium alone (18 µg by Handihaler) or combined with formoterol (12 µg twice daily by Aerolizer) in adults with moderate-to-severe stable COPD.
Objectives: The bronchodilator efficacy of a once-daily fixed-dose combination of tiotropium/formoterol (18/12 µg administered via a dry-powder inhaler, Discair) [TIO/FORMfixed group] vs a single-dose of tiotropium (18 µg) by Handihaler1 alone [TIOmono group], or combined with formoterol 12 µg twice-daily by Aerolizer2 [TIO/FORMbid group] was compared in patients with moderate-to-severe stable COPD. Methods: COPD patients were randomized (28 patients/group) to receive TIO/FORMfixed, TIOmono , or TIO/FORMbid. AUC for the changes in FEV1 and FVC over a 24-h period; bronchodilator response (100 ml improvement in FEV1) in the first 30 min; maximum changes in FEV1 and FVC; and safety data were recorded. ⋯ A positive bronchodilator response at 30 min was demonstrated in 50%, 64%, and 71% of patients in the TIOmono, TIO/FORMbid, and TIO/FORMfixed groups, respectively (NS). Maximum FEV1 and FVC changes were measured as 0.25/0.41 L, 0.32/0.49 L, and 0.37/0.53 L, for TIOmono, TIO/FORMbid, and TIO/FORMfixed, respectively (FEV1: TIO/FORMfixed vs TIOmono, p = 0.0017 and TIO/FORMfixed vs TIO/FORMbid, p = 0.4846); no differences were recorded between the combination groups. Conclusions: The 24-h bronchodilator efficacy of TIO/FORMfixed 18/12 µg once-daily by Discair3 was non-inferior to a combination of tiotropium 18 µg by Handihaler plus formoterol 12 µg twice-daily by Aerolizer, and superior to tiotropium 18 µg monotherapy by Handihaler.

Objective: To address gaps in the literature on healthcare resource utilization (HRU) and costs among patients with schizophrenia and prior hospitalization who transition from oral risperidone or paliperidone (oral ris/pali) to once-monthly paliperidone palmitate (PP1M) in a real-world setting by comparing treatment patterns, HRU, and costs 12-months pre- and post-transition to PP1M among Veterans Health Administration (VHA) patients affected by schizophrenia who have had ≥1 hospitalization. Methods: VHA patients with schizophrenia (aged ≥18 years) who initiated oral ris/pali, had ≥1 all-cause inpatient stay, and transitioned to PP1M from January 2015-March 2017 were included from the VHA database. The first transition date to PP1M was identified as the index date. ⋯ Cost outcome comparison indicated significantly lower all-cause inpatient costs ($64,702 vs $24,147, p < .0001), total medical costs ($87,917 vs $56,947, p < .0001), and total costs ($91,181 vs $69,106, p < .0001). A similar trend was observed for mental health and schizophrenia-related costs. Conclusions: Transitioning from oral ris/pali to PP1M may significantly improve HRU and provide potential cost savings in VHA patients with schizophrenia and ≥1 prior hospitalization.

Aims: To assess demographic and clinical characteristics associated with clinical inertia in a real-world cohort of type 2 diabetes mellitus patients not at hemoglobin A1c goal (<7%) on metformin monotherapy. Methods: Adult (≥18 years) type 2 diabetes mellitus patients who received care at Massachusetts General Hospital/Brigham and Women's Hospital and received a new metformin prescription between 1992 and 2010 were included in the analysis. Clinical inertia was defined as two consecutive hemoglobin A1c measures ≥7% ≥3 months apart while remaining on metformin monotherapy (i.e. without add-on therapy). ⋯ Chronic kidney disease and cardiovascular/cerebrovascular disease had weaker associations but were directionally similar to congestive heart failure. Conclusions: Asian patients were at an increased risk of clinical inertia, whereas patients with comorbidities appeared to have their treatment more appropriately intensified. A better understanding of these factors may inform efforts to decrease the likelihood for clinical inertia.
