Abstract: The objective of this work was to evaluate the inheritance of resistance to Cowpea aphid-borne mosaic virus (CABMV) in cowpea (Vigna unguiculata). The study was performed between parental genotypes IT85F-2687 (resistant) and 'BR-14 Mulato' (susceptible), generating F1, F2, and F7 populations and backcrosses with both parental genotypes. CABMV was inoculated on plants from all generations, which were then evaluated through visual inspection and description of characteristic symptoms. A chi-square test was performed after the phenotypic classification of all plants. A segregation proportion of 1:3 (resistant:susceptible) in population F2 and of 1:1 in population F7 was accepted, showing a recessive monogenic inheritance.

ABSTRACT Purpose Verify the position of lips and tongue at rest in newborns with and without ankyloglossia. Methods Cross-sectional study, carried out with 130 newborns in University Hospital. Data collection was performed by the researcher and speech-language pathologists from the Hospital. Information on gestational age, sex, weight, height and days of life was collected. The position of the lips and tongue at rest was evaluated through visual inspection with the newborns asleep. After the newborns were awakened, Neonatal Screening of the validated Protocol for the evaluation of the lingual frenulum for infants was performed to detect the alteration of the lingual frenulum. The data obtained were described and submitted to statistical analysis using the Chi-Square test to verify the association between the position of the lips with the tongue and to compare the position of the lips and tongue with and without ankyloglossia. The Mann-Whitney test was used to verify the behavior of the variables the differed between newborns with and without ankyloglossia. The significance level of 5% was adopted. Results When comparing the data, a significant difference was found between: weight and height with and without ankyloglossia; position of lips and tongue. An association between the position of the tongue and lips with and without ankyloglossia was also found. Conclusion Newborns without alteration of the lingual frenulum have a tendency to remain with their lips closed and their tongue elevated during rest and newborns with ankyloglossia have a tendency to keep their lips parted and their tongue low during rest.

Abstract The aims of this study were: 1) to evaluate the sports potential of young basketball players; 2) to identify variables that discriminate sports potential assessed by coaches; 3) to verifythe relationship between classification of the multidimensional profile of athletes and classification of the sports potential by coaches. Sixty-two young basketball players aged 15.6±1.1 years from U-15 (n = 24) and U-17 (n = 38) categories participated in the study. A test battery was applied to evaluate sports potential indicators: 1) anthropometric; 2) physicomotor; 3) psychological;4) skills;5) socio-environmental;6) maturational and 7) sports potential.Clusteranalysis was performed in three groups: high, medium and low potential. Student’s t-test was used for the comparison between athletes evaluated by the coach as excellent and the others and the Chi-Square test to verify the relationship between sports potential classifications. It was observed that in the high-potential group, athletes were chronologically older, with higher % predicted adult height (PMS), competitive and determined sports orientation, higher body size, lower skinfold summation, and greater physicomotor performance. In comparison with other athletes, high-potential basketball players presented higher stature, wider wingspan,longer limb length, greater predicted adult stature and higher Z score of the % PMS. It could be concluded that the multidimensional approach was useful for the evaluation of the sports potential of young basketball players, requiring the use of multidimensional variables, in addition to coaches’ opinion regarding the potential of their athletes.

Introduction:To evaluate cone-beam computed tomography (CBCT) images in order to determine the presence of mandibular second molars with C-shaped canal system and classify them.Methods:3035 CBCT images fulfilling the selection criteria were observed. Once established the presence of C-shaped canal system, they were classified according to the anatomic and radiographic classification of Fan et al. Data description was made by frequencies and percentages rates, with a 95% confidence interval (IC95) according to score method. Comparisons were assessed by means of the Chi-square test with a significance level equal to 5%.Results:Of the 225 selected patients, 44 exhibited C-shaped canals (20%; IC95: 15% to 25%). 70% (IC95: 56% to 82%) of patients showed a bilateral C-shaped canal system pattern. Regarding to the axial plane -anatomic classification-, there was a significant association between the root third and the configuration (Chi-square=76.89; p<0.05): at the coronal third prevailed the C1 configuration (47%; IC95: 36% to 58%); at the middle third prevailed the C3d configuration (39%; IC95: 28% to 50%) and at the apical third, the C4 configuration (35%; IC95: 25% to 46%).

Abstract Objective To determine the usefulness of a novel classification of indications for caesarean section (CS) in labour in recognizing differences in clinical practice in different maternity units. Methods Data from the National Perinatal Information System (NPIS) for 2013 and 2014 were used to classify indications for CS in nulliparous women with spontaneous onset of labour at ≥37 weeks with single cephalic foetuses within 14 Slovenian maternity units into foetal distress and different sub-groups of dystocia according to use and dosage of oxytocin. Chi-square test was used for statistical comparison between units (P≤0.05 significant). Results There were 13,572 deliveries and 1,567 (12.0%) CS in nulliparous patients with spontaneous onset of labour at ≥37 weeks with single cephalic foetuses in Slovenia during the study period. Rates of CS in this group of women differed significantly among different maternity units (from 4.1% to 20.9%; P<0.001) suggesting significant differences in clinical practice. The most common indication for CS was cephalopelvic disproportion, which was diagnosed with different frequency in different units (from 11.2% to 45.9%; odds ratio 6.72; 95% confidence interval 3.10– 14.71; P<0.001). Conclusions It is possible to use NPIS data to retrospectively classify indications for CS. Such classification reveals significant differences among maternity units and could allow for a meaningful analysis of CS rates in different hospitals leading to evidence-based initiatives to decrease the incidence of primary CS.

The objective of this work was to identify new sources of simple and multiple resistances to Cowpea severe mosaic virus (CPSMV), Cowpea aphid-borne mosaic virus (CABMV) and Cucumber mosaic virus (CMV) isolates in cowpea (Vigna unguiculata). Thirty-three genotypes from the germplasm bank of Universidade Federal do Ceará were tested as to their resistance to four CPSMV isolates, two CABMV isolates and one CMV isolate. Twenty-five days after the first virus inoculations, all inoculated plants, including the asymptomatic ones, were tested by serology. Genotypes were classified as: immune, plants without symptoms and negative serology; resistant, plants with mild mosaic and positive serology; susceptible, plants with mosaic and positive serology; and highly susceptible, plants with severe mosaic, other systemic symptoms, including systemic necrosis, and positive serology. Simple and multiple resistances to viruses were identified among the evaluated genotypes, but none of them showed multiple immunities to all isolates. Four genotypes showed immunity to all CPSMV isolates, two were immune to CABMV and two showed immunity to CMV. Eleven genotypes showed multiple resistances to two viruses, allowing for the development of new cultivars with more stable and broader resistance. Genotypes Purple Knuckle Hull-55, MNC-03-731C-21 and CNCx284-66E show resistance to CABMV, even when inoculated with CMV.

Early-onset scoliosis (EOS) can be a progressive and debilitating condition if left untreated. Different casting techniques have fallen in and out of favor over the years for conservative management. Two types of casting, elongation-derotation-flexion (EDF) and body casting (BC) are employed at our institution. Here we compare the radiographic outcomes between these two types of casting in a cohort of patients diagnosed with EOS. Sixteen children with EOS were treated by EDF serial casting while seventeen children with the same diagnosis were treated by BC. Radiographic measurements included Cobb angle, rib-vertebral-angle difference (RVAD) and vertebral rotation (VR) by Nash-Moe method in casting (IC) or out of casting (OOC), thoracic height (TH) and width (TW). All of the patients had x-ray measurements at pre-casting OOC, 1st IC and final post-casting OOC. Casts were changed every 2–4 months. Independent two sample t-test, Wilcoxon rank-sum test, and Chi-square test were performed. There were no significant differences at the initial treatment for age, classification of EOS, OOC, RVAD, VR, kyphosis, TH, and TW between EDF and BC casting. There were no significant differences of changes for OOC, RVAD, VR, kyphosis, TH and TW from pre-casting to the final post-casting status between two casting techniques (P>0.05). However, children with EDF tended to receive 3 to 4 more castings than those with BC (7.5 vs.4 casts) (P=0.007) and achieved better outcomes in success (25% vs.20%) and improvement (50% vs.10%) (P=0.03). EDF has better outcomes with EOS improvement when there is treatment of longer duration.

Rationale, aims and objectives: To support patients with mental disorders to address appropriate symptom control and preventive measures against relapse, evidence-based practice (EBP), such as psychoeducation, is an important intervention while performing psychiatric pharmacotherapy. However, the use of EBP is likely to have remained passive, as it has been reported being disseminated and implemented slowly. This study explored a classification of psychiatric nurses’ attitudes toward EBP and examined the association between a classification of attitudes toward EBP and needs for learning psychoeducation practices in nursing professionals involved with psychiatric services, with the aim of providing a basis for the dissemination of psychoeducation. Method: A mail questionnaire survey was conducted, involving a total of 194 nurses and assistant nurses working in 13 of the 42 psychiatric hospitals. Analysis was performed using the cluster analysis, chi-square test and one-way analysis of variance. Results: The psychiatric nurses’ attitudes toward EBP were classified into 3 types: experience-oriented challenging, amotivational and rejective and conservative and obedient. Nurses showing amotivational and rejective attitudes accounted for the majority, while those showing experience-oriented challenging attitudes were more aware of the usefulness of psychoeducation and their levels of need for learning related practices were higher on comparison with the others. Conclusions: In order to disseminate psychoeducation among psychiatric hospitals, it may be important to develop interest in psychoeducation, particularly that of nurses showing experience-oriented challenging or conservative and obedient attitudes, with co-operation from nursing managers.
