The use of an integrative approach to improve accuracy of species identification and detection of new species in studies of stream fish diversity.

In this study, we made an inventory of the stream and headwater ichthyofauna of the left bank of the Itaipu Dam Reservoir, located in the lower part of the Upper Paraná River basin, using an integrative approach of molecular and morphological data. The area is located in the western portion of the Paraná state in Brazil, in an area of about 8,000 km highly impacted by deforestation and intensive agriculture. For taxonomic identification of species, we used an identification key combined with the DNA barcoding approach.

High-Resolution Wavefront-Guided Photorefractive Keratectomy and Accelerated Corneal Crosslinking for Stabilization and Visual Rehabilitation of Keratoconus Eyes.

Purpose: To evaluate the visual and refractive outcomes after high-resolution wavefront-guided (HRWG) surface ablation with corneal crosslinking (CXL) in keratoconus eyes.

Patients And Methods: In this prospective, interventional case series, 47 eyes of 28 progressive keratoconus patients older than age 18 were enrolled. All patients underwent HRWG photorefractive keratectomy (PRK) with simultaneous accelerated CXL.

Naloxegol to Treat Constipation in a Patient Taking Opioids for Cancer Pain: A Case Report.

Opioid-induced constipation (OIC) is a common gastrointestinal adverse effect of opioids, which can severely affect compliance and adherence to pain medication regimens and quality of life. Naloxegol has demonstrated efficacy against OIC in several studies involving patients with nonmalignant chronic pain. Here we report efficacy and tolerability of naloxegol in a 68-year-old patient with metastatic lung cancer and severe pain, treated with opioids, who presented with OIC resistant to traditional measures.

[Concentration of Malondialdehyde in Subjects Living at High Altitudes: Exploratory Study].

The objective of this study was to determine the levels of malondialdehyde (MDA), an oxidative stress biomarker, in individuals living at high altitudes (3500-4200 m). This exploratory study evaluated 91 subjects from La Paz and El Alto using a questionnaire and clinical examination. MDA levels were measured using a colorimetric technique.

High-resolution wavefront-guided surface ablation with corneal cross-linking in ectatic corneas: a pilot study.

Purpose: A preliminary study to evaluate the outcomes of high-resolution wavefront-guided (HRWG) photorefractive keratectomy (PRK) with simultaneous corneal cross-linking (CXL) in ectasia eyes.

Methods: Sixteen eyes of 11 patients (mean age 31.9±9.

Sources of Information as Determinants of Product and Process Innovation.

In this paper we use a panel of manufacturing firms in Spain to examine the extent to which they use internal and external sources of information (customers, suppliers, competitors, consultants and universities) to generate product and process innovation. Our results show that, although internal sources are influential, external sources of information are key to achieve innovation performance. These results are in line with the open innovation literature because they show that firms that are opening up their innovation process and that use different information sources have a greater capacity to generate innovations.

Evaluation of the utilization of external radiotherapy in the treatment of localized prostate cancer in Andalusia, Spain.

Background: Around 27,000 new cases of prostate cancer are diagnosed every year in Spain and 5400 die from this disease. Radiotherapy (RT), alone or combined, has proven to be effective as initial treatment in patients with localized disease. Our objective was to evaluate the use of external beam RT (EBRT) in our region, comparing the indication rate and irradiation rate and examining variability in its application among hospitals.
