Abstract	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 (

Abstract	The association between FokI polymorphism in the vitamin D receptor (VDR) gene and susceptibility to arterial hypertension (HT) is controversial. Thus, we evaluated the relation between FokI and HT according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines using MEDLINE® (Medical Literature Analysis and Retrieval System Online)/PubMed, Scopus, and Cochrane Library CENTRAL databases. Data from case-control studies, including the number of participants, age, 25-hydroxyvitamin D concentrations, systolic and diastolic blood pressure values, FokI allele, and genotype frequency were extracted by 2 independent authors and OR was calculated with the 95% CI to assess the strength of the association between the FokI variant and odds of HT. In general and subgroup analyses, we used allelic (f compared with F), common (ff compared with FF + Ff), risk (ff + Ff compared with FF), and additive (ff compared with FF) models. Six case-control studies including 3140 cases and 3882 controls were reviewed in the meta-analysis. Global assessment revealed a correlation between FokI and reduced odds of HT in the additive/homozygote model (ff compared with FF; OR: 0.65; 95% CI: 0.45-0.94) and common/recessive model (ff compared with FF + Ff; OR: 0.75; 95% CI: 0.57-0.99). In Asian subjects, there was a significant reduction in the odds of HT in additive (ff compared with FF; OR: 0.84; 95% CI: 0.73-0.98) and risk models (ff + Ff compared with FF; OR: 0.87, 95% CI: 0.78-0.97), in particular, for Indians (South). In Africans, the statistically significant association occurred in the additive and common models. Allele f in the FokI polymorphism of the VDR gene was associated with reduced odds of HT in the general population based on the risk model. Thus, nutritional genomics can help understand the influence of nutrition on metabolic homeostasis pathways and the clinical consequences of hypertension. This study shows the need for healthy, anti-inflammatory, and antioxidant compounds to prevent or treat chronic complications.

Abstract	The dark matter in the Universe might be composed of superheavy particles (mass greater, similar 10(10) GeV). These particles can be detected via nuclear recoils produced in elastic scatterings from nuclei. We estimate the observable rate of strongly interacting supermassive particles (simpzillas) in direct dark matter search experiments. The simpzilla energy loss in Earth and in the experimental shields is taken into account. The most natural scenarios for simpzillas are ruled out based on recent EDELWEISS and CDMS results. The dark matter can be composed of superheavy particles only if these interact weakly with normal matter or if their mass is above 10(15) GeV.

Abstract	We consider models where the scale of supersymmetry breaking lies between 5 x 10(6) and 5 x 10(8) GeV. In this class of theories, which includes models of mediated supersymmetry breaking, the lightest supersymmetric particle is the gravitino, and the next to lightest is typically a long-lived charged slepton with a lifetime between a microsecond and a second, depending on its mass. We investigate the production of these particles by the diffuse flux of high energy neutrinos colliding with nucleons in the Earth, and the potential for their observation in large ice or water Cerenkov detectors. The small production cross section is partially compensated by the very long range of sleptons. The signal, two well-separated parallel tracks, has very little background. Using the Waxman-Bahcall limit for the neutrino flux results in up to four events a year in km3 experiments.

Abstract	OBJETIVO: Esta pesquisa foi realizada com o objetivo de comparar os valores da latência do P300 em crianças de 8 a 13 anos de idade, do sexo feminino e do sexo masculino, sem e com repetência escolar. FORMA DE ESTUDO: Estudo clínico com coorte transversal. MATERIAL E MÉTODO: Foram examinadas 60 crianças sem repetência e 43 crianças com repetência escolar. Todas as crianças foram submetidas à anamnese, audiometria tonal liminar, curva timpanométrica, reflexos auditivos contralaterais e o P300. RESULTADOS E CONCLUSÕES: Ao final desta pesquisa, concluiu-se que as crianças do grupo sem repetência escolar apresentaram valor da média aritmética da latência do P300 menor (332,25 ms), comparando-se ao grupo de crianças com repetência escolar (413,23 ms). As crianças do sexo feminino sem repetência escolar apresentaram valor da média aritmética da latência do P300 menor (328,37 ms), comparando-se às crianças do sexo masculino do mesmo grupo (337,68 ms). No grupo de crianças com repetência escolar, as crianças do sexo feminino também apresentaram valor da média aritmética da latência do P300 menor (387,50 ms), comparando-se às crianças do sexo masculino (423,19 ms). Finalmente, observou-se que os valores das médias aritméticas da latência do P300 apresentaram-se menores nas crianças do sexo feminino (328,37 ms) e do sexo masculino (337,68 ms) sem repetência escolar, comparando-se com os valores das médias aritméticas da latência do P300 nas crianças do sexo feminino (387,50 ms) e do sexo masculino (423,19 ms) com repetência escolar. AIM: This research was done with the objective to compare the values of latency of P300 in male and female kids 8 to 13 years of age, who have repeated at least a semester and who have not repeated any semester at school. STUDY DESIGN: Clinical study with transversal cohort. MATERIAL AND METHOD: Sixty kids who have never flunked at school and 43 kids who have already flunked were examined in public schools in Santa Maria. All kids were submitted to an anamnesis, pure tone audiometry, tympanometric curve, contra lateral reflexes auditory and P300. RESULTS AND CONCLUSION: At the end of this research it can be concluded that kids that have not repeated any year at school presented mean arithmetic latency value of P300 lower (332,25 ms), when compared to kids that have repeated (413,23 ms). Female children of the group that has no failure history at school have presented a mean arithmetic latency value of P300 lower (328,37 ms) than male kids (337,68 ms) of the same group. In the group of kids with failure history, the female kids have also shown mean arithmetic latency value of P300 lower (387,50 ms), compared to the male kids (423,19 ms). Finally lower mean arithmetic values of latency of P300 were observed in the group of both female (328,37 ms) and male kids (337,68 ms) who have not repeated at school when compared to the mean arithmetic values of latency of P300 in female (387,50 ms) and male kids (423,19 ms) who have repeated at school.

Abstract	Atualmente, podemos complementar os resultados encontrados na audiometria convencional com os obtidos nos exames eletrofisiológicos, o que nos permite diagnosticar não apenas uma perda auditiva periférica, mas também diferenciar uma perda auditiva coclear da neural, ou central. Isto nos conduziu a um grupo novo de pacientes que apresentava alteração na sincronia neural com função normal das células ciliadas externas. Esta patologia é conhecida como Neuropatia Auditiva. O objetivo deste estudo é descrever as características audiológicas de um paciente com Neuropatia Auditiva atendido no Centro de Docência e Pesquisa em Fonoaudiologia da Faculdade de Medicina da Universidade de São Paulo (FMUSP), correlacionando os achados com os encontrados na literatura. O caso descrito é de um indivíduo de 24 anos de idade, com o diagnóstico de Neuropatia Auditiva, atendido no ano de 2001 no Centro de Docência e Pesquisa em Fonoaudiologia da FMUSP. Foram realizados anamnese, audiometria tonal e vocal, medidas de imitância acústica, Emissões Otoacústicas (EOAs) e Audiometria de Tronco Encefálico (ABR). Observamos no caso estudado a incompatibilidade de resultados entre audiometria tonal e testes de inteligibilidade de fala, com os exames objetivos, EOAs e ABR, onde observou-se perda auditiva com importante alteração nos testes de inteligibilidade de fala, EOAs presentes e ABR anormal. Estes dados sugerem função coclear normal e alteração da sincronia neural. Nowadays, in our clinic, we can complement the conventional audiometry results with electrophysiologic exams. Not only does allow us to diagnose a peripheral hearing loss but also to differentiate cochlear, neural or central hearing loss. It led us to a new group of patients that presented changes in neural synchrony, with normal functions of the outer ear hair cells. This pathology is known as Auditory Neuropathy. Our study purpose is describe the audiologist characteristic of a patient with auditory neuropathy attended at "Centro de Docência e Pesquisa em Fonoaudiologia da Faculdade de Medicina da Universidade de São Paulo", correlating the study data with literature. The patient described is a 24 year-old person, with auditory neuropathy diagnosis, evaluated in our center in 2001. Interview, tonal audiometry thresholds, speech recognition, timpanometry, otoacustic emissions (OAEs) and auditory brainstem responses (ABR) were applied. In this case we observed incompatible results in the tonal audiometric threshold and speech recognition tests, with objectives tests like OAEs and ABR, in which we found a hearing loss with important changes in the speech recognition test, of OAEs present and abnormal ABR. These data suggest a normal cochlear function and abnormal neural synchrony.

Abstract	After the Phase-2 high-luminosity upgrade to the Large Hadron Collider (LHC), the collision rate and therefore the background rate will significantly increase, particularly in the high $\eta$ region. To improve both the tracking and triggering of muons, the Compact Muon Solenoid (CMS) Collaboration plans to install triple-layer Gas Electron Multiplier (GEM) detectors in the CMS muon endcaps. Demonstrator GEM detectors were installed in CMS during 2017 to gain operational experience and perform a preliminary investigation of detector performance. We present the results of triple-GEM detector performance studies performed in situ during normal CMS and LHC operations in 2018. The distribution of cluster size and the efficiency to reconstruct high $p_T$ muons in proton--proton collisions are presented as well as the measurement of the environmental background rate to produce hits in the GEM detector.
