title: New species of driftwood catfish of Tatia (Siluriformes: Auchenipteridae) from rio Tapajós, Brazil

description: Abstract A new species of Tatia is described from rio Tapajós, upstream of the rapids of São Luiz do Tapajós, Pará State, Brazil. The new species is identified and diagnosed from its congeners through morphological characteristics such as the absence of an adipose fin, which is shared with T. akroa and T. britskii; the composition of the cranial roof elements; the color pattern consisting of dorsolateral dark dots formed by both dermal and epidermal pigments; as well as several morphometric measures. The new species is a Centromochlinae fish that feeds on insects on the surface of the water at night and it is probably endemic to rio Tapajós basin.

title: Use of ketamine in treatment-resistant depression: a systematic review

description: ABSTRACT Objective Ketamine presents itself as a promising alternative against treatment-resistant depression (TRD), however, the knowledge of its application as an antidepressant is still restricted. Therefore, the objective was to investigate its effectiveness in patients with TRD. Methods The literature search was carried out in the MedLine database. Inclusion criteria were: controlled and randomized clinical studies from the last five years and in English. We excluded articles that did not answer the PICO question and those with different sample size and study methodology, when compared to the tests that based this review. Results Considering a final sample of six articles, a better response to ketamine was observed (mainly in mood gain), when compared to conventional treatment against TRD. With its first infusion, at a dose of 0.5 mg/kg, it was possible to notice its antidepressant effects. The maintenance of these effects seems to be achieved with the administration of 0.5 mg/kg of the drug, three times a week. On the other hand, the reduction of such a dosage can diminish or cancel the effects. Conclusions The use of ketamine showed effective results improving the condition of TRD, with adverse effects of small severity and easy control. However, further studies, with larger samples and different methods, are needed, for a more consistent conclusion.

title: Stress in dogs during grooming in a pet shop

description: ABSTRACT The objective was to study the stress level in dogs during grooming services in a pet shop. A total of 55 grooming services carried out in a pet shop in the city of Janaúba, MG, were evaluated and divided into four categories according to sex and body weight. The flowchart of the grooming process contained six steps that began with the transportation of dogs to the pet shop and finished with their return to the place of origin. Behavioral, physiological, and blood component evaluations were performed at different steps of the process. Changes in dog behavior and physiological parameters were observed primarily upon arrival at the pet shop and during drying. Employee characteristics also influenced dogs’ behaviors. However, dogs were able to thermoregulate and maintain the homeostasis of leukocytes, glucose and cortisol in the blood.

title: Gas exchange, growth and quality of guava seedlings under salt stress and salicylic acid

description: Abstract Guava is a popular Brazilian fruit that is widely produced in Northeastern Brazil, a region with water sources that commonly have high concentrations of salts. Thus, searching for techniques that allow the management of these waters is extremely important for the expansion of irrigated agriculture. In this context, salicylic acid is a phytohormone that can contribute to reducing the effects of salt stress on plants. Given the above, this study evaluated the effect of foliar application of salicylic acid at different concentrations in the mitigation of salt stress on gas exchange, growth, and quality of 'Paluma' guava seedlings. The experiment was conducted in a greenhouse, in Campina Grande - PB, Brazil, using a randomized block design in a 5 × 5 factorial arrangement, corresponding to five levels of electrical conductivity of water (0.6, 1.5, 2.4, 3.3, and 4.2 dS m-1) and five concentrations of salicylic acid (0 - Control; 0.8, 1.6, 2.4, and 3.2 mM), with four replicates and two plants per plot. Foliar application of salicylic acid at a concentration of up to 1.4 mM reduced the deleterious effects of salt stress on the instantaneous water use efficiency of 'Paluma' guava seedlings at 180 days after sowing. The concentrations of salicylic acid applied via foliar did not mitigate the harmful effects of irrigation water salinity on the growth and quality of 'Paluma' guava seedlings.

title: Endoscopic endonasal dacryocystorhinostomy learning curve

description: ABSTRACT Purpose: To compare the learning curves of the specialists in two different fields without previous endoscopic endonasal dacryocystorhinostomy experience as well as to reveal the related complications with surgical success rates. Methods: We retrospectively investigated 90 patients who received consecutive endoscopic endonasal dacryocystorhinostomy with mucosa preservation by an ophthalmologist (Group 1, n=45) and an otorhinolaryngologist (Group 2, n=45) between October 2017 and October 2019. Patients who were admitted with epiphora complaints and diagnosed with primary acquired nasolacrimal duct obstruction through lacrimal irrigation test and aged &gt;18 years with at least 6 months of follow-up were included in the study. In all cases, additional pathologies such as septum deviation were evaluated by performing maxillofacial imaging. Patients' medical records were evaluated in terms of surgery duration, complications, and functional achievements. Results: The mean surgical duration of the patients in Group-2 was 36.27 ± 11.61 min, while it was 43.62 ± 16.89 min in Group-1; the difference was statistically significant (p=0.018). Functional achievements in Group 1 was 84.4% (73.3% in the first set of 15 cases, 93.3% in the last set of 15 cases) in Group 2; this rate was 88.9% (80% in the first set of 15 cases, 93.3% in the last set of 15 cases), and the difference was not statistically significant (p=0.53). Septum intervention in addition to endoscopic surgery in both the groups (p=0.03, p=0.005, respectively) and intense bleeding during surgery (for both the groups, p&lt;0.0001) significantly decreased the functional success. Conclusion: Endoscopic endonasal dacryocystorhinostomy, performed after the necessary training, can provide high success and low complication rates when even conducted by ophthalmologists who are unfamiliar with endoscopic surgery after an experience of 30 cases.

title: SURGICAL TREATMENT IN CLINICAL STAGE IV GASTRIC CANCER: A COMPARISON OF DIFFERENT PROCEDURES AND SURVIVAL OUTCOMES

description: ABSTRACT - BACKGROUND: Even in clinical stage IV gastric cancer (GC), surgical procedures may be required to palliate symptoms or in an attempt to improve survival. However, the limited survival of these patients raises doubts about who really had benefits from it. AIM: This study aimed to analyze the surgical outcomes in stage IV GC treated with surgical procedures without curative intent. METHODS: Retrospective analyses of patients with stage IV GC submitted to surgical procedures including tumor resection, bypass, jejunostomy, and diagnostic laparoscopy were performed. Patients with GC undergoing curative gastrectomy served as the comparison group. RESULTS: Surgical procedures in clinical stage IV were performed in 363 patients. Compared to curative surgery (680 patients), stage IV patients had a higher rate of comorbidities and ASA III/IV classification. The surgical procedures that were performed included 107 (29.4%) bypass procedures (partitioning/gastrojejunal anastomosis), 85 (23.4%) jejunostomies, 76 (20.9%) resections, and 76 (20.9%) diagnostic laparoscopies. Regarding patients’ characteristics, resected patients had more distant metastasis (p=0.011), bypass patients were associated with disease in more than one site (p&lt;0.001), and laparoscopy patients had more peritoneal metastasis (p&lt;0.001). According to the type of surgery, the median overall survival was as follows: resection (13.6 months), bypass (7.8 months), jejunostomy (2.7 months), and diagnostic (7.8 months, p&lt;0.001). On multivariate analysis, low albumin levels, in case of more than one site of disease, jejunostomy, and laparoscopy, were associated with worse survival. CONCLUSION: Stage IV resected cases have better survival, while patients submitted to jejunostomy and diagnostic laparoscopy had the worst results. The proper identification of patients who would benefit from surgical resection may improve survival and avoid futile procedures.

title: Valorization of Hesperidin from Citrus Residues: Evaluation of Microwave-Assisted Synthesis of Hesperidin-Mg Complex and Their Insecticidal Activity

description: The aim of the current study was the valorization of hesperidin, the dominant flavonoid in citrus processing waste, by microwave-assisted synthesis of hesperidin-Mg complex, improving its antioxidant activity and insecticidal potential. Here we show, for the first time, that microwave-assisted synthesis of [Mg(hesp)2(phen)]OAc (1) (hesp: hesperidin, phen: phenanthroline) improve the reaction rate and yield. The nuclear magnetic resonance (NMR) experiments proved to be powerful tools for the identification of three isomers in metal complexes. Moreover, we explore the insecticidal potential of 1 and [Mg(phen)2(Isov)]OAc (2) (Isov : isovanillic acid) complexes against three insects. Complex 1 killed 80% of adults whitefly at 0.14 μmol L-1, and 2 76% at 0.36 μmol L-1. There was a total mortality of Spodoptera frugiperda with 2 at 0.39 μmol L-1, and 83% with 1 at 0.14 μmol L-1. Both have similar activity, and represent a novel group of insecticide for Bemisia tabaci and S. frugiperda; nevertheless, the benefits of both as Myzus persicae repellent require further evaluation.

title: Effectiveness of functional orthodontic appliances in obstructive sleep apnea treatment in children: literature review

description: Abstract Introduction: Obstructive sleep apnea syndrome is a common condition in childhood and if left untreated can result in many health problems. An accurate diagnosis of the etiology is crucial for obstructive sleep apnea treatment success. Functional orthodontic appliances that stimulate mandibular growth by forward mandibular positioning are an alternative therapeutic option in growing patients. Objective: To perform a literature review about the effects of functional orthodontic appliances used to correct the mandibular deficiency in obstructive sleep apnea treatment. Methods: The literature search was conducted in June 2020 using Cochrane Library; PubMed, EBSCO (Dentistry & Oral Sciences Source), LILACS Ovid; SciELO Web of Science; EMBASE Bireme and BBO Bireme electronic databases. The search included papers published in English, until June 2020, whose methodology referred to the types and effects of functional orthopedic appliances on obstructive sleep apnea treatment in children. Results: The search strategy identified thirteen articles; only four articles were randomized clinical studies. All studies using the oral appliances or functional orthopedic appliances for obstructive sleep apnea in children resulted in improvements in the apnea-hypopnea index score. The cephalometric (2D) and tomographic (3D) evaluations revealed enlargement of the upper airway and increase in the upper airspace, improving the respiratory function in the short term. Conclusion: Functional appliances may bean alternative treatment for obstructive sleep apnea, but it cannot be concluded that they are effective in treating pediatric obstructive sleep apnea. There are significant deficiencies in the existing evidence, mainly due to absence of control groups, small sample sizes, lack of randomization and no long-term results.
