Randomized Controlled Trial
Effects of transcutaneous electrical nerve stimulation (TENS) and interferential currents (IFC) in patients with nonspecific chronic low back pain: randomized clinical trial.
Transcutaneous electrical nerve stimulation (TENS) and interferential current are the most used electrotherapy methods, although there is little scientific evidence to support their use. The aim of this study was to compare the effects of TENS and interferential current among patients with nonspecific chronic low back pain. ⋯ NCT01017913.

Comparative Study
Who are the low-risk patients that could benefit from watch-and-wait regarding the neck?
The management of clinically negative neck is controversial, with an ongoing debate on the indication criteria and prognostic impact of different types of therapy. The aim here was to compare the results from neck dissection and watch-and-wait, among oral cancer patients who, clinically, did not show any evidence of neck metastasis. ⋯ Elective neck dissection seems to be the best treatment option. Patients who are eligible for watch-and-wait constitute a small group that, ideally, is categorized according to the postoperative pathological findings.

Anesthesiologist-patient relationships are established preoperatively and intraoperatively. These are opportunities for providing correct information about anesthesia/anesthesiologists, thereby improving outcomes. The aim here was to evaluate patients' perceptions about anesthesiologists before anesthesia and to identify whether the anesthetic care would change such perceptions. ⋯ Patients' perceptions of anesthesiologists' roles were fairly good, but improvements in this relationship still need to be pursued, to achieve better outcomes. Anesthetic care was important in providing information, confidence and reassurance among patients, regarding their perceptions. Anesthesiologists should not miss opportunities to provide excellent professional care for patients, thereby improving anesthesia outcomes and their image.

Early diagnosis of prediabetes should be done to avoid complications relating to diabetes mellitus (DM). The aim here was to assess the prevalence of prediabetes among individuals at high risk of developing DM, and to seek variables relating to glucose intolerance (GI) among individuals with normal fasting plasma glucose (FPG). ⋯ The prevalence of prediabetes was 68.0%, and 20.0% of subjects with normal FPG had GI. Although some anthropometric, clinical and laboratory variables have been correlated with DM and prediabetes, none, except for GTT, was able to screen for GI among subjects with normal FPG in the present study.
