To assess the benefits of long-term nucleos(t)ide analogue (NA) therapy in reducing the severity and progression of liver disease in treatment-naïve patients with chronic hepatitis B (CHB). ⋯ Long-term administration is generally advised in all CHB patients treated with NAs because of the high rates of virological and clinical relapse after stopping therapy. The findings of this analysis lend support to the choice of highly potent agents with a low drug resistance profile to maximize viral suppression in CHB patients and halt or delay progression to end-stage liver disease.

Multicenter Study Observational Study
Improvement in condition-specific and generic quality of life outcomes in patients with knee osteoarthritis following single-injection Synvisc: results from the LOBRAS study.
To evaluate the effectiveness of viscosupplementation with single-injection hylan G-F20 (Synvisc-One) in knee osteoarthritis (OA), during routine clinical care, in a 52 week observational study. ⋯ The effectiveness of single-injection hylan G-F20 in routine clinical care is supported by the detection of statistically significant, clinically important improvements in WOMAC Pain, Stiffness, Function, Total, and PGA outcomes, and statistically significant improvements in SF-36 PCS and WOMAC-derived HUI3 outcomes at multiple time points. Limitations of this study include lack of a control group or blinding. No predictive indicators of the response to treatment were identified. In general single-injection hylan G-F20 was well tolerated with very few patients experiencing any treatment-related adverse events. Collectively, these observations attest to the effectiveness of single-injection hylan G-F20 and complement previous observations in routine clinical care.

Patients with type 2 diabetes (T2D) often have coexisting chronic kidney disease (CKD). However, healthy renal function is crucial in maintaining glucose homeostasis, assuring that almost all of the filtered glucose is reabsorbed by the sodium glucose cotransporters (SGLTs) SGLT-1 and SGLT-2. In diabetes, an increased amount of glucose is filtered by the kidneys and SGLT-2 is upregulated, leading to increased glucose absorption and worsening hyperglycemia. ⋯ Caution is advised when prescribing SGLT-2 inhibitors to patients with moderately impaired renal function and those at risk for volume depletion and hypotension. Published data on slowing of the development, as well as progression of CKD, is a hopeful indicator for the possible renal protection potential of this drug class. This narrative review provides an in-depth discussion of the interplay between diabetes, SGLT-2 inhibitors, and factors that affect kidney function.

The objective of this study was to assess the timely disclosure of results of company-sponsored clinical trials related to all new medicines approved by the European Medicines Agency (EMA) during 2013. This is an extension of two previously reported studies of trials related to all new medicines approved in Europe in 2009, 2010 and 2011, and in 2012. The original study found that over a three year period over three-quarters of all trials were disclosed within 12 months and almost 90% were disclosed by the end of the study. The extension study (2012 approvals) showed an improvement in results disclosure within 12 months to 90%, and an overall disclosure rate of 92% by the end of the study. ⋯ The disclosure rate within 12 months of 90% suggests that industry is continuing to achieve disclosure in a timely manner. The overall disclosure rate at study end of 93% indicates that the improvement in transparency amongst company-sponsored trials has been maintained in the trials associated with new medicines approved in 2013.

The Bowel Function Index (BFI) is a simple and sound bowel function and opioid-induced constipation (OIC) screening tool. We aimed to develop the translation and cultural adaptation of this measure (BFI-P) and to assess its reliability and validity for the Portuguese language and a chronic pain population. ⋯ This study had some limitations, namely, the criterion validity of BFI-P was not directly assessed; and the absence of a direct criterion for OIC precluded the assessment of the criterion based responsiveness of BFI-P. Nevertheless, BFI may importantly contribute to better OIC screening and its Portuguese version (BFI-P) has been shown to have excellent reliability, internal consistency, validity and responsiveness. Further suggestions regarding statistically and clinically important change cut-offs for this instrument are presented.
