Purpose: Hemispheric dominance is associated with more activity in one half of the body, which is very important in the presence of a relationship between the intelligence and brain lateralization. Delayed language development in the children undergoing cochlear implantation can have deleterious effects on their growth, academic performance, adaptation, and social interactions. Regarding this, the present study aimed to determine the relationship between the dominant hand and intelligence in the 4-16 year-old children undergoing cochlear implantation in the left or right ear. Methods: This cross-sectional study was conducted on the records of the patients aged within 4-16 years who had undergone cochlear implantation during 2008-2011. The subjects’ IQ was measured using Wechsler test by a neuroscience specialist. Then, the IQ of the children with the right cochlear implant was compared to that of those with left implant. The data were analyzed using the t-test, Fisher’s exact test, Mann-Whitney U test, and Chi-square test in SPSS version 18. Results: According to the results, there was no significant difference between the children with right and left cochlear implants in terms of the mean IQ score (P=0.54). Furthermore, no significant association was observed between IQ score and right-handedness or left-handedness in the children undergoing cochlear implantation (P=0.17, P=0.8, respectively). Conclusion: As the findings indicated, there was no relationship between the dominant hand and IQ score in the children undergoing cochlear implantation.

Objective: To evaluate patient perception of the smile focused on analysis of the upper incisors. Design: Cross-sectional study. Setting: Department of Clinical and Social Dentistry at Federal University of Paraíba, João Pessoa, Brazil. Participants: The sample consisted of 135 individuals (73 women and 62 men). Methods: Images with different characteristics associated with the incisal edges were shown at random and analysed using a Likert scale. Data were analysed using the Chi-square test or Fisher’s exact test with a statistically significant difference ( P < 0.05). Results: Smile I (difference of 1.5 mm in relation to the central incisor and lateral) was considered the most aesthetic, while Smile III (no difference in height between the central and lateral incisors) was the least aesthetic. A significant difference was found between perception of smile II (difference of 1 mm in relation to the central incisor and lateral) and age groups ( P < 0.005), with 31% (n = 13) of individuals aged 45–64 years considering smile II as not pleasant, 4.4% (n = 2) aged 15–24 years and 8.3% (n=4) aged 25–44 years and 4.4% (n = 2) aged 15–24 years considering the same. A significant difference was also found in relation to educational background of the assessor and smile perception, with smile III ( P = 0.0441) and smile IV ( P = 0.0053) considered the most aesthetic ( P = 0.0116). Conclusion: The smile considered most attractive among the sample was that with 1.5 mm steepness between the central and lateral incisors, while a flat smile arc was considered least attractive.

Objective This study was done to compare the dental and oralhygiene status of children with and without congenital heart dis-ease (CHD) by investigating oral microorganisms and dental andoral hygiene indices.Methods A cross-sectional study was done on children aged 2 to15 years from April 2002 to December 2003 at the Department ofChild Health, Haji Adam Malik Hospital, Medan. There were twosubject groups, the first consisting of children with CHD and thesecond of those without. The dental and oral hygiene status wasdetermined by determining caries index and oral hygiene index.Swabs from the subjects’ upper first molars were taken and cul-tured to determine the types of microorganisms present. Data wereanalyzed using the chi-square test, Fisher’s exact test, and t-test.Results There was a significant difference in mean oral hygieneindex between children with (mean 2.75; SD 1.85) and without(mean 1.45; SD 0.78) CHD (P<0.001). Positive bacterial cultureswere more frequent in children with CHD than in those without.The proportion of normal anaerobes was significantly higher in chil-dren with CHD (P=0.038). Such a significant difference was notfound for normal aerobes, pathogenic aerobes, and pathogenicanaerobes. In children with CHD, there was no significant asso-ciation between mean caries index and oral hygiene index withculture results. In those without CHD, a significant association wasfound between the caries index components of decayed tooth in-dex (P=0.003) and DMF-T (P=0.022) with culture results.Conclusions Oral-dental hygiene in children with CHD is poorrelative to that in children without CHD. Microorganism growth ap-pears more likely in children with CHD than in those without

Objective: assess the adherence levels to antiretroviral therapy in people coinfected with HIV/tuberculosis and correlate these levels with the sociodemographic and clinical variables of the study population. Method: cross-sectional study involving 74 male and female adults coinfected with HIV/tuberculosis. For the data collection, a sociodemographic and clinical assessment form and the Antiretroviral Treatment Adherence Assessment Questionnaire were used. For the data analysis, the software STATA version 11 was used, through descriptive statistics, Fisher's chi-square exact test and the probability test. Results: men were predominant (79.7%), between 30 and 39 years of age (35.1%), low income (75.7%) and pulmonary tuberculosis (71.6%). Adherence to antiretroviral therapy was inappropriate in 78.1% of the men; 61.0% of single people; 47.0% unemployed and 76.5% among people gaining less than one minimum wage. A significant difference was observed between compliance and length of use of antiretrovirals (p=0.018), sexual orientation (p=0.024) and number of children (p=0.029). Conclusion: the coinfected patients presented inappropriate adherence to the antiretrovirals, a fact that negatively affects the health conditions of the people living with HIV/tuberculosis coinfection. A statistically significant correlation was found between the levels of adherence and some sociodemographic and clinical characteristics.

ABSTRACT Objective: to determine the prevalence of use in life and in the last three months of alcohol, marijuana and cocaine among university students from the social and health Sciences areas of Ribeirão Preto, Brazil and to evaluate the association between use in life and in the last three months of alcohol, marijuana and cocaine and the variables gender, area of the course, with whom the student lives, importance of religion, age and year of study. Method: a cross-sectional study, carried out with a convenience sample of 275 students from a public university in Ribeirão Preto-SP. For data collection, two instruments were used, containing sociodemographic, training and psychoactive substances. For the analysis, the following tests were used: Fisher's exact test, Chi-square test of Person and Mann-Whitney test. Results: As for sociodemographic factors, there was a significant association between the gender of the participants among the use of marijuana and cocaine in life (p=0.024 and p=0.005, respectively) and the last three months (p=0.013 and p=0.009, respectively), among the importance of religion and the lifetime use of alcohol, marijuana and cocaine (p <0.001, p <0.001 and p = 0.024, respectively) and the use of only marijuana in the last three months (p <0.001) and among the use of marijuana in the last three months and the year of graduation (p=0.003). Regarding age, the results showed a significant difference only between the groups that reported not to use alcohol in life (p=0.037). Conclusion: the investigated university students presented a prevalence of use in their lifetime and in the last three months of marijuana and cocaine greater among men, but not for alcohol. The importance of religion was negatively associated with the use of investigated drugs. The results can provide important subsidies for the structuring of preventive measures for abuse of psychoactive substances between university students and the need for new investigations that cover the subject.

Abstract Background Clinicians in critical care medicine considered dapsone administration to treat SARS-CoV-2 inflammasome. Dapsone is useful in the molecular regulation of Nod-like receptor family pyrin domain-containing 3 (NLRP3). Objective To study the targeting of NLRP3 itself or up-/downstream factors of the NLRP3 inflammasome by dapsone must be responsible for its observed preventive effects, functioning as a competitor. Methods This is case series with or without intervention; a cross-sectional study. We set out to use objective criteria of improvement, such as A. a reduction in the FIO2 requirement and B. a decrease in the progression of hypoxia. We treated the patients with standard COVID-19 ARDS treatment with dapsone 100 mg to target NLRP3 inflammasomes. Results The 22 cases were treated with standard COVID-19 therapy with dapsone (trial group), and the 22 cases were the control group. The comparison was made assuming that only decreased FIO2 was influential in the trial and control groups, which applied to only the ARDS onset stage. The chi-square statistic is 5.1836. The p-value is .02280. Fisher’s exact test statistic value is 0.0433. (The result is significant at p < .05) Furthermore, the ARDS-onset mortality rates were 0% (with dapsone) and 40% (without dapsone). Conclusion There was a significant difference in dapsone treatment results in the ARDS-onset group. We confirmed that dapsone clinically treated the onset of ARDS by targeting SARS-CoV-2-activated inflammasomes. Like chemically reacting substances, inflammasome and dapsone are competing, proving that it is only effective in treating early ARDS.

Introdução: Nas últimas décadas aumentou o número de pessoas acima do peso, incluindo crianças e adolescentes, fato que é considerado preocupante, pois pode acarretar diversas doenças crônicas, em longo prazo.Objetivo: Avaliar a prevalência de sobrepeso e obesidade em escolares de um colégio militar, investigando possíveis diferenças entre os sexos e as faixas etárias.Métodos: Estudo quantitativo, transversal, do qual participaram 381 escolares de um colégio militar de Minas Gerais, de 11 a 17 anos, sendo 213 meninos e 168 meninas. Calculou-se o índice de massa corporal (IMC) que foi classificado segundo o PROESP-BR. Para testar diferenças entre os sexos, utilizou-se o teste do Qui-Quadrado (X2) e para testar a relação entre idade e IMC, utilizou-se a correlação de Pearson. Significância estatística: p < 0,05.Resultados: Foi observado sobrepeso em 17,8% (n = 68) e de obesidade em 5,8% (n = 22) dos escolares. Houve correlação positiva entre a idade cronológica e o IMC (r = 0,32; p < 0,0001). Não houve correlação entre estado nutricional e faixa etária. Não foram observadas diferenças significativas entre os sexos, em relação ao sobrepeso e à obesidade (16,9% e 6,6% nos meninos vs. 19,0% e 4,8% nas meninas, respectivamente).Conclusão: A prevalência sobrepeso e obesidade nos escolares do colégio militar, em conjunto, foi de 23,6%, tanto nos meninos quanto nas meninas, sem diferença significativa entre as faixas etárias. Essa prevalência foi similar à média de escolares brasileiros.Prevalence of Overweight and Obesity in Students of a Military SchoolIntroduction: Over the past few decades, the number of overweight people, including children and adolescents has increased significantly, a fact that is considered worrying, as it can lead to several chronic diseases in the long term.Objective: To evaluate the prevalence of overweight and obesity in schoolchildren of a military college, investigating possible differences between sexes and age groups.Methods: A quantitative, cross-sectional study was carried out in which 381 students from a military school in Minas Gerais, aged 11 to 17 years, were 213 boys and 168 girls. The body mass index (BMI) was calculated according to the PROESP-BR. To test for gender differences, the Chi-square test (X2) was used and Pearson's correlation was used to test the relationship between age and BMI. Statistical significance: p <0.05.Results: Overweight was observed in 17.8% (n = 68) and obesity in 5.8% (n = 22) of the students. There was a positive correlation between chronological age and BMI (r = 0.32; p <0.0001). There was no correlation between nutritional status and age range. No significant differences were observed between genders regarding overweight and obesity (16.9% and 6.6% in boys vs. 19.0% and 4.8% in girls, respectively).Conclusion: The prevalence of overweight and obesity in the students of the military college, together, was 23.6% in both boys and girls, with no significant difference between age groups. This prevalence was similar to the average of Brazilian schoolchildren.

Abstract Objective: To identify the prevalence of diabetes and its relation to associated factors in elderly persons receiving care at a specialist gerontology-geriatric outpatient service. A descriptive cross-sectional study of 301 elderly persons of both genders was performed. Method: The bivariate analysis was performed using the Pearson’s Chi-square test for Independence and Fisher's exact test, considering 5% of significance and 95% confidence. A multivariate logistic regression model was adjusted to identify factors that may influence the occurrence of diabetes. Result: There was no statistically significant association between the prevalence of diabetes and socioeconomic and demographic variables, behavioral factors and health conditions. Only the Body Mass Index variable was close to being statistically significant (p=0.059). Conclusion: The result confirms the need to develop new studies on the subject to consider the particularities and specificities of the elderly population to enable the creation of educational intervention strategies aimed at this group.

Background: The mounting trends of beauty perceptions have contributed to distorted body image among adolescents. This demands understanding about current pointers of body image satisfaction to prevent eating disorders associated with mismanagement of weight in adolescents. Aim & Objective: The objectives of this cross-sectional study were to apprehend body image perception and dissatisfaction among adolescents (12-14years) across the genders and associate it with their actual BMI along with identifying the factors influencing body image perception. Settings and Design: A structured questionnaire was developed and administered on randomly selected 112 adolescents (68% boys & 34% girls, 12-14 years), mean age=12.8 ±0.45 from urban coeducational school of western India. Anthropometric measurements were taken with standardized tools and BMI z-scores were calculated. The actual and perceived weight was compared using paired t-test and descriptive statistics. Association between body image indicators, gender, and BMI were assessed using Chi-square test and One-way ANOVA. Factor analysis was done by Principal component analysis. Results: There was a significant difference in the perceived (M=2.31, SD=0.93) and actual BMI (M=1.96, SD=0.69), p=0.002. A significant association between gender and the influence of media idols, discrimination due to physical appearance and BMI was observed (p≤.0.005).   Self-perception and judgements of others, behaviors related with self-fixation, social influence and inappropriate dietary practices and comparison with models and actors were the emerging factors identified. Conclusion: The body image perception was distorted among adolescents of both sexes, with higher body image discontent shown by girls. The perceived body image, when compared with their BMI was found to be incongruent across sexes.

Purpose The aims of this study were to characterize hearing symptoms, habits, and sound pressure levels (SPLs) of personal audio system (PAS) used by young adults; estimate the risk of developing hearing loss and assess whether instructions given to users led to behavioral changes; and propose recommendations for PAS users. Method A cross-sectional study was performed in 50 subjects with normal hearing. Procedures included questionnaire and measurement of PAS SPLs (real ear and manikin) through the users' own headphones and devices while they listened to four songs. After 1 year, 30 subjects answered questions about their usage habits. For the statistical analysis, one-way analysis of variance, Tukey's post hoc test, Lin and Spearman coefficients, the chi-square test, and logistic regression were used. Results Most subjects listened to music every day, usually in noisy environments. Sixty percent of the subjects reported hearing symptoms after using a PAS. Substantial variability in the equivalent music listening level (Leq) was noted ( M = 84.7 dBA; min = 65.1 dBA, max = 97.5 dBA). A significant difference was found only in the 4-kHz band when comparing the real-ear and manikin techniques. Based on the Leq, 38% of the individuals exceeded the maximum daily time allowance. Comparison of the subjects according to the maximum allowed daily exposure time revealed a higher number of hearing complaints from people with greater exposure. After 1 year, 43% of the subjects reduced their usage time, and 70% reduced the volume. A volume not exceeding 80% was recommended, and at this volume, the maximum usage time should be 160 min. Conclusions The habit of listening to music at high intensities on a daily basis seems to cause hearing symptoms, even in individuals with normal hearing. The real-ear and manikin techniques produced similar results. Providing instructions on this topic combined with measuring PAS SPLs may be an appropriate strategy for raising the awareness of people who are at risk.
