Observational Study
Occurrence of adverse events among patients with inflammatory bowel disease in the HealthCore Integrated Research Database.
Inflammatory bowel disease (IBD) is a chronic condition commonly requiring lifelong care. Both IBD and IBD-related treatments can cause significant morbidity, and it is often difficult to differentiate their relative etiologic contribution to adverse events (AEs). The objectives of this study were to assess the rates of select AEs among patients with IBD as a function of disease severity and of the use of anti-tumor necrosis factor alpha (anti-TNFα) medications. ⋯ Results from this large US cohort provide descriptive information on AE rates in a population of IBD patients undergoing routine care, estimating background incidence rates of AEs that are not readily available in the published literature. Our study findings may be limited owing to a lack of generalizability and potential for misclassification due to reliance on medical diagnosis and treatment and procedure codes to identify disease, comorbidities, and treatments. Further research and validation of our findings in other populations and databases are needed.

Randomized Controlled Trial Multicenter Study Comparative Study
A randomized study to compare the efficacy and safety of extended-release and immediate-release tramadol HCl/acetaminophen in patients with acute pain following total knee replacement.
To evaluate the relative efficacy and safety of extended-release tramadol HCl 75 mg/acetaminophen 650 mg (TA-ER) and immediate-release tramadol HCl 37.5 mg/acetaminophen 325 mg (TA-IR) for the treatment of moderate to severe acute pain following total knee replacement. ⋯ Clinicaltrials.gov, NCT01814878.

Randomized Controlled Trial Multicenter Study Comparative Study
Safety and efficacy of oxycodone/naloxone vs. oxycodone vs. morphine for the treatment of chronic low back pain: results of a 12 week prospective, randomized, open-label blinded endpoint streamlined study with prolonged-release preparations.
Opioid-induced constipation (OIC) is the most prevalent patient complaint associated with opioid use and interferes with analgesic efficacy. ⋯ Under the conditions of this PROBE design, OXN was associated with a significantly better tolerability, a lower risk of OIC and a significantly better analgesic efficacy than OXY or MOR.

It remains uncertain whether remote ischemic conditioning (RIC) could prevent acute kidney injury (AKI) in patients undergoing percutaneous coronary intervention (PCI). Thus, this meta-analysis aiming to explore the renoprotective role of RIC in patients undergoing PCI was carried out. ⋯ RIC may not only confer cardioprotection, but also reduce the incidence of AKI in patients undergoing PCI, ultimately leading to better clinical outcomes. RIC may potentially be a powerful approach conferring protection in patients undergoing PCI in future clinical practice. More large-scale trials are required to obtain a more reliable conclusion.

Randomized Controlled Trial Multicenter Study
Intraocular pressure decrease with preservative-free fixed and unfixed combination of tafluprost and timolol in pseudoexfoliative glaucoma.
We investigated the intraocular pressure (IOP) lowering efficacy of preservative-free fixed and non-fixed combination of tafluprost 0.0015% and timolol 0.5% in pseudoexfoliative glaucoma (XFG). A per protocol worse eye analysis was made on all XFG patients who participated in a recent 6 month, prospective, randomized, double-masked, parallel group, multicenter phase III study. The mean time-wise IOP decreased by 8.62 to 10.25 mmHg (31.8 to 36.7%) in the fixed dose combination arm (15 patients) and by 5.38 to 11.35 mmHg (21.3 to 41.2%) in the non-fixed combination arm (13 patients), respectively (p < 0.001 for all comparisons). The results show that a preservative-free fixed dose combination of tafluprost and timolol provides a clinically significant IOP reduction in XFG, and may offer an advantage for the XFG patients with dry eye, due to its preservative-free nature.
