Meta Analysis
The efficacy of pregabalin in patients with moderate and severe pain due to diabetic peripheral neuropathy.
Objective To compare the therapeutic response to pregabalin in patients with moderate or severe painful diabetic peripheral neuropathy (pDPN). Research design and methods Data were pooled from 11 placebo-controlled trials to evaluate the efficacy of pregabalin flexible or fixed dose (150, 300 or 600 mg/day) in pDPN patients with mean baseline pain scores of ≥4 to <7 (moderate) or ≥7 to ≤10 (severe). Last observation carried forward imputation was used. ⋯ Conclusions Pregabalin was effective in pDPN patients with both moderate and severe baseline pain. Patients with severe pain exhibited greater improvements in pain and PRSI than patients with moderate pain. Pain severity may, in part, predict therapeutic response to pregabalin.

Objective The sodium-glucose cotransporter 2 (SGLT-2) inhibitors are an important addition to available treatments for patients with type 2 diabetes (T2D) as an adjunct to modifications in diet and exercise. SGLT-2 inhibitors may be prescribed alone or as add-on treatment in patients receiving metformin, sulfonylureas, thiazolidinediones, dipeptidyl peptidase-4 inhibitors, and/or insulin across the natural history of the disease. Inhibition of SGLT-2, which is responsible for approximately 90% of renal glucose reabsorption, increases urinary glucose excretion and lowers blood glucose concentrations. ⋯ Adverse events associated with SGLT-2 inhibitors include mild to moderate urinary tract and genital infections and mild dehydration potentially leading to orthostatic hypotension. Conclusions An evidence-based practice approach to examining the importance of early, proactive treatment of T2D using SGLT-2 inhibitors from initiation of pharmacotherapy to increasingly more complicated combination therapy regimens, including insulin, suggests that this treatment strategy maximizes benefits and minimizes potential side effects. The SGLT-2 inhibitors augment the arsenal of available antidiabetes agents, facilitating the ability of clinicians to design tailored treatment regimens that help patients achieve therapeutic goals.

Objective To report on the failure rate of spinal catheters placed following inadvertent dural puncture (IDP) compared with re-sited epidural catheters in the obstetric population. Research design and methods Patients who experienced IDP during epidural or combined spinal epidural placement with 17 or 18 gauge Tuohy needles for labor analgesia between 2003 and 2014 were identified using our post-dural puncture headache (PDPH) database. Patients were categorized into two groups: those who had spinal catheters inserted and those who had epidural catheters re-sited. ⋯ There was also no difference in the rate of adverse events including high block levels, hypotension, and fetal bradycardia (9% vs. 7%, P = 1.0) between the two groups. Conclusions There were no differences in failure rates, PDPH outcomes, or adverse events between spinal catheters and re-sited epidural catheters following IDP in parturients receiving labor analgesia. Limitations of the study include its single-center retrospective non-randomized design, and the uneven number of patients in the two groups with a relatively small number in the re-sited epidural catheter group.

Objective Management of patients with type 2 diabetes (T2DM) and stage 3 to 5 chronic kidney disease (CKD) is challenging. The aim of the 'LEARN' study was to describe treatment patterns employed in this population and to record comorbidities, glycemic control and hypoglycemia episodes in routine clinical practice in Greece. Research design and methods 'LEARN' was a non-interventional, multicenter, cross-sectional study conducted in Greece between 15 February 2013 and 4 July 2013. ⋯ Moreover, patients receiving oral antidiabetics only had experienced fewer hypoglycemia episodes over the last 7 days prior to the study visit (0.1 ± 0.4) compared to patients receiving insulin only (0.9 ± 1.7) (p = 0.03). Conclusions Although this is an observational study, it seems that oral antidiabetic therapy might be advantageous for heavily burdened T2DM patients with moderate or severe CKD in terms of glycemic control and hypoglycemia episodes. More data preferably from randomized trials is needed in order to validate this hypothesis.

Objective Though the median age at diagnosis is 64 years, few studies focus on elderly (≥65 years) patients with chronic myeloid leukemia (CML). This study examines healthcare outcomes among elderly Medicare beneficiaries with CML who started nilotinib or dasatinib after imatinib. Research design and methods Patients were identified in the Medicare Research Identifiable Files (2006-2012) and had continuous Medicare Parts A, B, and D coverage. ⋯ Conclusions In the current study of elderly CML patients, initiation of second-line TKIs frequently occurs at doses lower than the recommended starting doses and, despite this, many patients require dose adjustments. Here, nilotinib patients required fewer dose adjustments than dasatinib patients. Further research focusing on elderly CML patients is warranted in order to help define future best clinical practices.
