title: Analysis of prognostic factors for Tis-2N0M0 early glottic cancer with different treatment methods

description: Abstract Introduction In many regions, laryngeal carcinoma is a common upper respiratory tract cancer, most commonly involving the glottic region. The treatment of early glottic cancer includes radiotherapy, open surgery and laryngeal laser microsurgery. However, the preferred treatment for early glottic cancer is still controversial. Objectives To study the factors affecting the 5-year survival rate of Tis-2N0M0 early glottis cancer and to demonstrate the oncological safety of different treatments. Methods 144 patients with early glottic cancer were analyzed retrospectively. All patients were clinically node negative. 53 patients underwent open surgery, transoral CO2 laser microsurgery in 46 cases and radiotherapy in 45 cases. The patients were followed up for 26 − 84 months, with an average follow-up period of 62.9 months. Results The 5-year overall survival was 82.6%. The 5 year survival rates of open surgery, laser microsurgery and radiotherapy were 83.0%, 82.6% and 82.2%, respectively. There was no significant difference in 5-year survival rate among the three treatments (p= 0.987). In multivariate analysis, age, T-stage, pathological grading, and anterior commissure involvement were important prognostic factors for early glottic cancer. Conclusion There was no significant difference in 5 year survival rate among patients treated by either radiotherapy, laser microsurgery or open surgery for early glottic cancer. We urge more attention to the age, T-stage, pathological grade, and anterior commissure involvement of the patients.

title: Does size of the cochlear nerve affect postoperative auditory performance in pediatric cochlear implant patients with normal cochlear nerves?

description: Abstract Introduction Cochlear implantation is an effective treatment method for severe to profound hearing loss. Many factors that may influence cochlear implantation success have been explained in previous studies. Apart from those, minor differences in size of normal cochlear nerves may affect postoperative performance. Objective To investigate whether the minor differences in cochlear nerve size in normal cochlear nerves affect postoperative cochlear implant performance. Methods 30 pediatric prelingually deaf patients who were treated with cochlear implantation were included in this study. From the reconstructed parasagittal magnetic resonance images, the diameter and cross-sectional area of the cochlear nerve on the ipsilateral and contralateral side were measured. Auditory evaluations were performed 1, 3, 6 and 12 months following the first fitting. All the analysis was performed by using EARS®, evaluation of auditory responses to speech tool. Correlation between cochlear nerve diameter, cross-sectional area and postoperative auditory perception was analyzed to determine whether variation in cochlear nerve size contributes to postoperative auditory performance. Results The mean diameter of the cochlear nerve on the ipsilateral side was 718.4 μm (504.5 − 904.3 μm) and mean cross sectional area was 0.015 cm2 (0.012 − 0.018 cm2). On the contralateral side the mean cochlear nerve diameter was 714.4 μm (502.6 − 951.4 μm) and mean cross sectional area was 0.014 cm2 (0.011 − 0.019 cm2). The correlation between the diameter and cross-sectional area of the ipsilateral and contralateral cochlear nerve revealed no significance. Mean score at first month monosyllable-trochee-polysyllable test, MTP1, was 0.17 (0.08 − 0.33), at 6th month with 6 words test, 6th month MTP6 was 0.72 (0.39 − 1.0), at 6th month with 12 words, 6th month MTP 12 was 0.46 (0.17 − 0.75) and at 12th month with 12 words, 12th month MTP12 was 0.73 (0.25 − 1.0). There was no correlation between the monosyllable-trochee-polysyllable test, values at any time with the diameter of the ipsilateral cochlear nerve. However, the first month MTP, 6th month MTP6 and 12th month MTP12 correlated with the cross-sectional area of the ipsilateral cochlear nerve. Conclusion Measuring the cross sectional area of the normal- appearing cochlear nerve may give important prognostic knowledge on cochlear implant outcomes. In patients with a larger cross sectional area the auditory performance was better and faster. Although normal appearing, slight differences on cross sectional area of the cochlear nerve may affect performance. Measuring the size of the cochlear nerve on parasagittal magnetic resonance images may provide beneficial information on the postoperative rehabilitation process.

title: Productivity, physicochemical quality and early flowering resistance of experimental onion hybrids

description: ABSTRACT In order to produce bulbs or seeds, onion plants depend on genotype X environment interaction. Thus, breeders shall select the genotypes based on the climatic conditions of each producing region. This study aimed to evaluate 17 experimental onion hybrids and two commercial genotypes (‘Bella Dura’ and ‘Buccaneer’), based on agronomic, physicochemical attributes of the bulbs and resistance to early flowering under subtropical conditions. Joint analysis of variance and phenotypic divergence estimated through principal component analysis (PCA) and Ward’s hierarchical clustering were performed. We observed that the time of transplantation affected the agronomic traits more than the physicochemical traits, not affecting the percentage of early flowering of the genotypes. The first transplant season provided higher bulb productivity, whereas the second season reduced the cycle and productivity. Hybrids H1, H17 and ‘Buccaneer’ showed flowering rate lower than 3%. Among the experimental hybrids, H2 showed higher productivity when comparing with commercial cultivars, and H1, H12 and H14 were equivalent to them. However, H12 showed the highest early flowering rate (43%). Thus, considering the experimental genotypes evaluated under subtropical conditions, H1, H2, and H14, showed potential for commercial use or as potential parents in advancing the breeding program, as they stood out for presenting good yield, bulb quality and low percentage of early flowering.

title: Postharvest quality of two sweet potato cultivars submitted to different harvest ages

description: ABSTRACT The quality of sweet potato roots is influenced by factors which precede harvest. Thus, the aim of this study was to correctly determine the harvest point and study the postharvest quality of two sweet potato cultivars harvested at different ages. The experiment was carried out at Universidade Federal de Roraima. The plants were grown from April to August, during rainy season, 2020. The harvest was carried out at 80, 95, 110, 125 and 140 days after planting (DAP). The tuberous roots were cleaned and the physicochemical traits of the pulp and peel were evaluated. Soluble solids, titratable acidity and SS/AT ratio were observed in greater quantity in the cultivar BD-02. The luminosity and chroma of the peel of the sweet potato roots were more intense in the cultivar BD-01 and the opposite was observed when characterizing the pulp of this cultivar. At 110 DAP, we verified the highest levels of reducing sugars and chroma of the peel, as well as lower values for the chroma of the pulp and °H of the peel. Thus, according to the results presented above, especially in relation to carbohydrate metabolism, productivity and dry matter accumulation, the cultivar BD-02, harvested at 110 DAP, showed the best postharvest traits under the experimental conditions presented in this study.

title: Anatomical relationship of pterygoid process pneumatization and vidian canal

description: Abstract Introduction The vidian canal acts as landmark for the identification of the petrous carotid artery, especially during extended endoscopic endonasal approaches in cranial base surgeries. In order to localize the canal and to understand the relationship of pneumatization of pterygoid process to the type of vidian canal, this study was designed. Objectives The objective was to describe the anatomical relationship of pneumatization of the pterygoid process with types of vidian canal. The length of vidian canal, relationship to medial plate of pterygoid process and relationship to the petrous part of internal carotid artery were evaluated. Methods Head computer tomography scans of 52 individuals for suspected paranasal pathology were studied. The degree of sphenoid sinus pneumatization, pterygoid process pneumatization and types of vidian canal (type 1, 2 and 3) were noted. The length of vidian canal, distance from the plane of medial pterygoid plate and relation of vidian canal to the junction of petrous and Gasserian (ascending) part of internal carotid artery was noted. Results 46 (92%) sphenoid sinuses were of the sellar variety. Out of 104 sides that were studied, 57 sides demonstrated a pneumatised pterygoid process and 47 were not pneumatised. In 49 sides (47.1%) the vidian canal was on the same plane as that of the medial pterygoid plate in the coronal section. The vidian canal partially protruded into the sphenoid sinus (type 2) was the most common type (50.9%), found both on right and left sides. There is a statistically significant association between the pterygoid process pneumatization and occurrence of type 2 and type 3 vidian canal configuration. The average length of the vidian canal was 16.16 ± 1.8 mm. In 96 sides, the anterior end of vidian canal was inferolateral to petrous part of internal carotid artery in the coronal plane. Conclusion Pneumatization of the pterygoid process indicates either type 2 or type 3 vidian canal configuration.

title: Financial ‘globalization’ and exchange rate regimes

description: ABSTRACT This paper argues that, although international capital flows have increased rapidly in recent decades, financial markets are still far from forming a unified global market. It also argues that the effect of increasing capital mobility on national economic policy autonomy continues to depend, to a large extent, on the choice of the exchange rate regime.

title: Emotional and Clinical Aspects Observed in Women with Gestational Trophoblastic Disease: A Multidisciplinary Action

description: Abstract Objective To evaluate the emotional and clinical aspects observed in women with gestational trophoblastic disease (GTD) followed-up in a reference center (RC) by a multidisciplinary team. Methods Retrospective cohort study of the clinical records of 186 women with GTD and of the emotional aspects (EA) observed in these women by a teamof psychologists and reported by the 389 support groups conducted from 2014 to 2018. Results The women were young (mean age: 31.2 years), 47% had no living child, 60% had planned the pregnancy, and 50% participated in two or more SG. Most women (n=137; 73.6%) reached spontaneous remission ofmolar gestation in a median time of 10 weeks and had a total follow-up time of seven months. In the group of 49 women (26.3%) who progressed to gestational trophoblastic neoplasia (GTN), time to remission after chemotherapy was 18 weeks, and total follow-up time was 36 months. EA included different levels of anxiety and depression,more evident in 9.1% of the women; these symptoms tended to occur more frequently in women older than 40 years (p=0.067), less educated (p=0.054), and whose disease progressed to GTN (p=0.018), as well as in those who had to undergo multi-agent chemotherapy (p=0.028) or hysterectomy (p=0.001) adjuvant to clinical treatment. Conclusion This study found several EA in association with all types of GTD. It also highlights the importance of specialized care only found in a RC, essential to support the recovery of the mental health of these women.
