RESUMEN
INTRODUCTION: Health technology assessment (HTA) plays a vital role in healthcare decision-making globally, necessitating the identification of key factors impacting evaluation outcomes due to the significant workload faced by HTA agencies. OBJECTIVES: The aim of this study was to predict the approval status of evaluations conducted by the Brazilian Committee for Health Technology Incorporation (CONITEC) using natural language processing (NLP). METHODS: Data encompassing CONITEC's official report summaries from 2012 to 2022. Textual data was tokenized for NLP analysis. Least Absolute Shrinkage and Selection Operator, logistic regression, support vector machine, random forest, neural network, and extreme gradient boosting (XGBoost), were evaluated for accuracy, area under the receiver operating characteristic curve (ROC AUC) score, precision, and recall. Cluster analysis using the k-modes algorithm categorized entries into two clusters (approved, rejected). RESULTS: The neural network model exhibited the highest accuracy metrics (precision at 0.815, accuracy at 0.769, ROC AUC at 0.871, and recall at 0.746), followed by XGBoost model. The lexical analysis uncovered linguistic markers, like references to international HTA agencies' experiences and government as demandant, potentially influencing CONITEC's decisions. Cluster and XGBoost analyses emphasized that approved evaluations mainly concerned drug assessments, often government-initiated, while non-approved ones frequently evaluated drugs, with the industry as the requester. CONCLUSIONS: NLP model can predict health technology incorporation outcomes, opening avenues for future research using HTA reports from other agencies. This model has the potential to enhance HTA system efficiency by offering initial insights and decision-making criteria, thereby benefiting healthcare experts.

PURPOSE: To investigate oropharyngeal structures and functions in a pediatric population with Down Syndrome (DS) and obstructive sleep apnea (OSA) and to correlate with the apnea/hypopnea index (AHI) and sleep questionnaires. METHODS: 12 Children with DS and OSA, between the age of 4 and 12 years old, underwent polysomnography (PSG); sleep questionnaires, Pediatric Sleep Questionnaire (PSQ) and Obstructive Sleep Apnea-18 (OSA-18); and speech-language evaluation using the Short Evaluation of Orofacial Myofunctional Protocol (ShOM). RESULTS: There was a positive correlation between ShoM higher scores and the apnea-hypopnea index (AHI) and between ShoM and the number of hypopneas. The orofacial myofunctional alterations observed in the studied group were: oral breathing, alteration in lip tonus and competence, tongue posture at rest and in swallowing, and occlusal alteration. There was also an increased risk for OSA according to the sleep questionnaires, as well as the presence of obesity and overweight, but without correlation with the severity of OSA. CONCLUSION: All DS children show alterations in orofacial characteristics, higher scores being associated to severe OSA. Orofacial myofunctional evaluation may help to identify different phenotypes in Down syndrome children with Obstructive sleep Apnea, enhancing the need for a multidisciplinary approach.
OBJETIVO: Investigar as estruturas e funções orofaríngeas de uma população pediátrica com Síndrome de Down (SD) e apneia obstrutiva do sono (AOS) e correlacionar com o índice de apneia/hipopneia (IAH) e questionários do sono. MÉTODO: 12 Crianças com SD e AOS, entre 4 e 12 anos, foram submetidas à polissonografia (PSG); questionários do sono, Pediatric Sleep Questionnaire (PSQ) e Obstructive Sleep Apnea-18 (OSA-18); e triagem fonoaudiológica por meio do Short Evaluation of Orofacial Myofunctional Protocol (ShOM). RESULTADOS: Verificou-se uma correlação positiva entre pontuações mais elevadas no ShOM e o índice de apneia hipopneia (IAH) e entre o ShOM e número de hipopneias. As alterações miofuncionais orofaciais observadas no grupo estudado foram: respiração oral, alteração no tônus e competência labial, na postura de língua em repouso e na deglutição e alteração oclusal. Verificou-se também, um risco aumentado para AOS conforme os questionários do sono, bem como presença de obesidade e sobrepeso, mas sem correlação com a gravidade da AOS. CONCLUSÃO: Todas as crianças apresentaram alterações miofuncionais orofaciais, sendo que escores mais altos no ShOM, ou seja, um maior comprometimento miofuncional orofacial, estavam associados à maior gravidade de AOS, sugerindo que a avaliação miofuncional orofacial dentro de uma abordagem multidisciplinar pode auxiliar na identificação de fatores de risco para AOS em crianças com SD.

OBJECTIVE: To measure the average time for the diagnosis and for the therapeutic prescription of Continuous Positive Airway Pressure (CPAP) at a hospital in Botucatu Medical School - State University São Paulo, UNESP. METHOD: A retrospective observational study was carried out by collecting data from the electronic medical records of patients over 18-years of age, who had a diagnostic polysomnography testing scheduled between January and December 2017. RESULT: Of the 347 patients eligible for the study, 94 (27.1%) missed follow-up and 103 (29.7%) had a referral for CPAP use. Until February 2021, only 37 (35.9%) of these patients had already acquired and were using the device, the remaining 66 (64.1%) were waiting or gave up the therapy. The mean value of the waiting time interval between the referral of the diagnostic test and its performance was equivalent to 197 days (6.5 months). The mean time between diagnostic polysomnography and CPAP prescription was 440-days (14.5-months), with a total mean time of 624 days (21-months). CONCLUSION: As in other services, the diagnostic-therapeutic flow proved to be highly inefficient, with a long waiting period, difficult access to treatment and a high dropout rate. These findings highlight the need to establish new patient-centered strategies with measures that speed up the flow and facilitate access to CPAP, in order to reduce the morbidity and mortality associated with this condition. LEVEL OF EVIDENCE: Level 3 - Non-randomized controlled cohort/follow-up study Recommendation B.

OBJECTIVES: To evaluate the effectiveness of maxillomandibular advancement surgery in the treatment of Obstructive Sleep Apnea by comparing the pre- and postoperative Apnea and Hypopnea Index, in addition to classifying the degree of evidence and risk of intervention bias. METHODS: A systematic review of the literature was carried out in the PUBMED, LILACS, EMBASE, SCOPUS, WEB OF SCIENCE and COCHRANE platforms, including cohort studies with polysomnographic follow-up, without other associated pharyngeal or nasal surgical procedures. The risk of study bias was assessed using the Modified Delphi technique. Pre- and postoperative Apnea and Hypopnea Index data were plotted for meta-analysis, and the quality of evidence was assessed using the GRADE system. RESULTS: Of 1882 references, 32 articles were selected for full-text reading, of which four studies were included, totaling 83 adults with obstructive sleep apnea who underwent maxillomandibular advancement. The meta-analysis was in favor of the intervention (DMâ¯=â¯-33.36, 95% CI -41.43 to -25.29, pâ¯<â¯0.00001), with a mean percentage reduction in the Apnea and Hypopnea Index of 79.5% after surgery, even though the level of evidence was classified as very low quality by the GRADE system. CONCLUSION: The meta-analysis was in favor of the intervention, characterizing maxillomandibular advancement surgery as an effective treatment for obstructive sleep apnea in adults.

Introduction The exposure of medical students to a full-time schedule that includes classes, extracurricular activities, patients' lives responsibility, and great competition between classmates can interfere in emotional issues and in the sleep time. Objective The aim of the present study was to evaluate the sleep quality, and the incidence of anxiety and depression in medical school undergraduates as well as the relationship of these parameters with the intense use of technologies. Methods Fifty-five medical school undergraduates in their second year participated in the present study, answering questionnaires to evaluate sleep quality (Pittsburgh sleep quality index - PSQI), night-time use of technology (sleep time-related information and communication technology - STRICT), and signs of anxiety or depression (hospital anxiety and depression scale - HADS). Results The results showed 31 students (56.4%) with poor sleep quality (PSQI > 5). Based on the STRICT questionnaire, 36 (65.4%) of the participants referred to making use of technology at night-time; and 34 (61.8%) students had compatible anxiety score, while 14 (25.4%) had a compatible score for depression on the HADS questionnaire. There has been a correlation between poor sleep quality, the abuse of technologies before sleep time, and the presence of anxiety or depression. Conclusion The abuse of technology before sleep time reduced the sleep quality in the studied population, besides increasing the symptoms of anxiety and depression.
RESUMEN
OBJECTIVES: This study aimed to evaluate the impact of the COVID-19 pandemic on Brazilian health technology assessment processes based on public reports from the National Committee for Health Technology Incorporation (CONITEC). METHODS: This descriptive study analyzed CONITEC's official reports on Brazil available on its website between 2018 and 2021 that aimed to propose recommendations for technologies to be incorporated into its public healthcare system. We used descriptive statistics covering the number of technologies and number of reports about drugs per year, objective, type of technology, demanding sector, and outcome before 2018 to 2019 and during the COVID-19 pandemic (2020-2021). Furthermore, we used logistic regression to explore any association between the final decision labeled as "incorporated" and the emergence of the COVID-19 pandemic. RESULTS: A total of 278 reports were analyzed. Approximately 85% (136 of 278), 79% (220 of 278), and 45% of the reports (125 of 278) were about drugs, for incorporation, and requested by the government, respectively. Moreover, 74 of 130 (57%) and 56 of 148 decisions (38%) were "incorporated" before and during the pandemic, respectively. No significant association was noted between incorporated decisions and the arrival of the COVID-19 pandemic for all technologies (odds ratio 1.43; 95% CI 0.84-2.46; P = .192) and for drugs (odds ratio 1.43; 95% confidence interval 0.81-2.53; P = .223) while adjusting for the type of technology and demandant. CONCLUSIONS: The COVID-19 pandemic has brought many challenges, but it does not seem to have had a significant impact on the health technology assessment approval decisions of CONITEC in Brazil.

BACKGROUND: Obstructive sleep apnea (OSA) is associated with a negative impact on neurocognitive development in children. Receptive/expressive oral language is a complex process, with limited investigations on the repercussion of OSA. This study aimed to analyze receptive and expressive oral language skills in children with obstructive sleep apnea (OSA). METHODOLOGY: This study included 52 children (27 females, 51.92 %) with a mean age of 7 ± 2 years (age range of 4-11 years), which underwent type 3 polysomnography (PSG). The participants were divided into N-OSA (n = 16) and OSA (n = 36) groups based on the apnea-hypopnea index. The speech-language therapist evaluated hearing and oral language for phonology, expressive semantics, syntax, receptive semantics (Peabody Image Vocabulary Test), pragmatics, and understanding of verbal instructions (Token Test). RESULTS: Oral language assessments showed a difference in the pragmatics subsystem (p = 0.047), with positive correlation between OSA severity and oral language functions such as pragmatics and syntax (desaturation index, p = 0.045). CONCLUSION: Obstructive sleep apnea (OSA) had a negative impact on oral language skills, including the syntax and pragmatics subsystems.

Objective: To analyze the relation among insomnia, excessive daytime sleepiness and the excessive use of technologies in medical students. Methods: The study was approved by the Local Ethics Committee of the institution. Students from the 1st and 2nd year of medical graduation students participated. Three questionnaires were used: Sleep Time-Related Information and Communication Technology, Insomnia Severity Index and the Epworth Sleepiness Scale. The data were described and compared by gender and year of graduation by the Students T Test, and correlated to the use of technology, insomnia and excessive daytime sleepiness by Pearsons Correlation (adopted the significance level of p <0.05). Results: 106 students (41 male) participated, expressing perception of insomnia in 76.4%, 34% with excessive daytime sleepiness, and 38.3% had a high use of technology related to sleep. There was a correlation between the use of technologies both with insomnia (r = 0.393; p = < 0.001), as well as with excessive daytime sleepiness (r = 0.228; p = 0.019). Conclusion: An important frequency of insomnia was found associated with the excessive use of technologies at the bed, with repercussions of daytime sleepiness. This demonstrates the importance of actions to raise awareness and education about correct sleep hygiene in medical students.
RESUMEN
INTRODUCTION: Obesity is the most frequent reversible agravating factor of obstructive sleep apnea syndrome, with physical activity very important for its control. Continuous positive air pressure during sleep is the "gold standard" treatment for obstructive sleep apnea syndrome. OBJECTIVE: we aimed to investigate if the use of continuous positive air pressure for a short period (7 days), would improve sleep quality, daytime sleepiness, and the disposition for physical activity. METHODS: Eighty obstructive sleep apnea syndrome patients were randomly assigned as follows: group I - continuous positive air pressure with a steady pressure of 4â¯cm H2O; group II - ideal therapeutic pressure. After filling out the questionnaires related to the studied variables (International physical activity questionnaire long-form, Epworth sleepiness scale, Pittsburgh sleep quality index), patients underwent a baseline pulmonary function test and continuous positive air pressure titration. After continuous positive air pressure therapy for 4≥ hours a night for 7 consecutive days, patients returned and filled out new (International physical activity questionnaire long-form, Epworth sleepiness scale, Pittsburgh sleep quality index) forms. New spirometry was carried out. RESULTS: 39 patients completed the study. The mean age was 52⯱â¯11 years old and 28 patients (71.79%) were obese. Both groups were similar for all variables studied at baseline. After Continuous positive air pressure use, patients of group II presented more significant improvements (pâ¯<⯠0.05) for sleep quality and diurnal sleepiness. Time spent with physical activities did not change. Spirometric data were at normal range at baseline. Solely the variable FEF 25%-75% was significantly enhanced (pâ¯<⯠0.05) in group II. CONCLUSION: Continuous positive air pressure therapy for 1 week, with ideal pressure, improves daytime sleepiness and sleep quality, enhances pulmonary function, but does not change the mean time spent with physical activities.

INTRODUCTION: Obstructive sleep apnea syndrome is a high-prevalence disorder found in the population. Studies have shown a possible association between nasal obstruction and obstructive sleep apnea syndrome, but the existence of a association between the degree of nasal obstruction and obstructive sleep apnea syndrome severity has not yet been proven. OBJECTIVE: To evaluate the internal nasal dimensions of adults with primary snoring and obstructive sleep apnea syndrome by acoustic rhinometry and to correlate the findings with obstructive sleep apnea severity. METHODS: Twenty-one male Caucasian subjects with complaints of snoring and/or respiratory pauses during sleep, aged between 18 and 60 years of age, were evaluated. After clinical evaluation, otorhinolaryngological examination and flexible nasopharyngolaryngoscopy, all patients underwent type III polysomnography. The participants were divided into two groups according to symptom severity: group 1, primary snoring and/or mild obstructive sleep apnea syndrome(nâ¯=â¯9) and group 2, moderate/severe obstructive sleep apnea syndrome (nâ¯=â¯12). Internal nasal dimensions were measured by acoustic rhinometry, analyzing minimum cross sectional area (CSA) and three nasal segment volumes. RESULTS: The respiratory event index corresponded to 8.1⯱â¯4.0 in group 1 and 47.5⯱â¯19.1 in group 2. In group 1, the cross-sectional areas values, in cm2, corresponded to: CSA 1â¯=â¯1.1⯱â¯0.4; CSA 2â¯=â¯2.1⯱â¯0.9; CSA 3â¯=â¯3.5⯱â¯1.8 and, in group 2: CSA 1â¯=â¯1.2⯱â¯0.3, CSA 2â¯=â¯2.0⯱â¯0.5; CSA 3â¯=â¯2.8⯱â¯0.7. In group 1, volumes (V), in cm3, corresponded to: V1â¯=â¯3.5⯱â¯1.0; V2â¯=â¯9.3⯱â¯5.0; V3â¯=â¯40.2⯱â¯21.5 and in group 2 a: V1â¯=â¯3.6⯱â¯0.5; V2â¯=â¯7.6⯱â¯1.5; V3â¯=â¯31.5⯱â¯6.7. Cross-sectional area and volume ââdid not differ between groups. CONCLUSION: There were no significant differences in the cross-sectional areas and nasal volumes between individuals with primary snoring-mild obstructive sleep apnea syndrome and moderate-severe obstructive sleep apnea syndrome. Differently to the raised hypothesis, our results suggest that there is no association between internal nasal dimensions and severity of obstructive sleep apnea syndrome.

OBJECTIVES: To investigate the evidence on the association between ankyloglossia and obstructive sleep apnea. METHODS: An integrative literature review was carried out in the databases. Observational and interventional studies that assessed the lingual frenulum in children with sleep-disordered breathing were included. As exclusion criteria: studies in animals, in vitro, letters to the editor, expert opinions, other reviews. The selected articles were analyzed regarding the study design, sample, characterization of the lingual frenulum and sleep assessment, in addition to the main results and conclusions. RESULTS: Ninety-seven articles were identified, but only 4 met the inclusion criteria. Two retrospective studies concluded that the untreated shortened lingual frenulum at birth is associated with obstructive sleep apnea. A prospective study concluded that there was an improvement in speech and deglutition after lingual frenectomy, in addition to improved sleep. A retrospective cohort concluded that lingual frenuloplasty combined with myofunctional therapy is effective in the treatment of snoring and mouth breathing. CONCLUSION: The studies included in this review contribute to corroborate the association between ankyloglossia and obstructive sleep apnea.

OBJECTIVE: To evaluate the economic and technical viability of the sleep study (type III) in children with adenotonsilar hypertrophy. METHODS: 141 children were submitted to sleep study (type III), aged between three and 11, all with symptoms of OSA. The frequency of failed examinations and a comparison of cost analysis between complete polysomnography were described. RESULTS: 41 exams lost at least one sensor. The sensor with the highest number of losses was the oximetry, observed in 14.28%. The 100 valid sleep studies allowed the diagnosis of severe OSA in 36 children. Sleep study accounts for approximately 63% of the value of the PSG type I, thus, it showed to be cost effective even with the repetition of the failed one. CONCLUSION: Sleep study (type III) may have high failure rates and it was a reliable exam for the identification of severe OSA. The cost analysis showed economic feasibility, even with a high failure rate and necessity of repetition.
RESUMEN
INTRODUCTION: Adenotonsillectomy is an invasive surgical procedure, which may encourage the search for information by the lay population through online search engines. The quality of this information, however, requires an evaluation due to the wide diversity of the available content. OBJECTIVE: To evaluate the quality, in terms of ethical principles, readability and comprehensiveness, of the most accessed websites concerning guidance to parents/guardians related to their children's recommended adenotonsillectomy. METHODS: The websites mentioned on the first 10 pages obtained after the search using "removal", "tonsils" and "adenoids" as keywords, after applying the inclusion and exclusion criteria, were selected. All were assessed using the Flesch Readability Index and Health on the Net Code tools, in addition to an evaluation of the content by two independent evaluators. The data were described, and the inter-rater agreement was calculated by the Kappa coefficient. RESULTS: 34 websites were found, of the 100 assessed ones, which met the inclusion and exclusion criteria using the Google and Yahoo! Tools. Sixteen (47%) pages were considered reasonably difficult/difficult to read according to the Flesch Readability Index. Most of them met less than half of the analyzed ethical requirements according to the Health on the Net Code, and the overall comprehensiveness average was considered insufficient. CONCLUSION: A deficit of overall quality (comprehensiveness, readability, and ethical principles) was demonstrated for the websites available to parents or guardians about the adenotonsillectomy procedure in children.

Introduction The quality of information on websites about tonsillectomy regarding the knowledge level may be low. Tonsillectomy is a surgical procedure to hypertrophy of the palatine and pharyngeal tonsils. So, it is an invasive procedure with possible complications, which creates insecurity in parents. Significantly, Internet searches have been increased to address possible health concerns, questioning the quality of websites about tonsillectomy. Objective To evaluate the readability, reliability, and comprehensiveness of the Italian websites dedicated to parental guidance regarding the indications for tonsillectomy in children. Methods The search engine google.it was used to search the websites. The Gulpease index, which is a widely used readability formula ranging from 0 (difficult) to 100 (easy readability), was employed to evaluate these websites. The Health on the Net Code of Conduct (HONcode) was used to assess the quality of information, by taking ethical principles into account, with values ranging from 0 to 13. The content comprehensiveness of the web pages was assessed by assigning points ranging from 1 (very insufficient) to 5 (very satisfying) to each page. A final comparison with previous studies on tonsillectomy published on websites from other countries was performed. Results Fourteen Italian websites were selected, and the Gulpease index showed a mean average of 40.77 ± 8.45. The mean of the HONcode analysis was 6.00 ± 1.92, in which the principles with the poorest scores were Attribution and Update . As far as the comprehensiveness of the websites is concerned, the resulting mean was 2.57 ± 0.77, in which Indications was the topic with the highest mean, whereas Benefits was the one with the lowest. Conclusion The Italian websites were characterized by a lower readability level, a middle position regarding ethical principles, and the same (insufficient) comprehensiveness of tonsillectomy when compared with websites from different countries.
RESUMEN
OBJECTIVE: To study the incidence of mouth breathing and its association with sleep disorders, dental caries, malocclusion and deleterious oral habits, in children. MATERIAL AND METHODS: 152 children (6 to 9 years), of both genders, were invited to perform clinical evaluation of the oral cavity and the application of the OSA-18. RESULTS: 89 presented mouth breathing (MB), being 45% with malocclusion, 56% with dental caries, 38% with tooth loss, 51% with bruxism and 52% with the habit of sucking ï¬nger or paciï¬er, compared to 40%, 40%, 21%, 27% and 43%, respectively, in the 63 children with nasal breathing (NB). 35 MB showed moderate to high risk for OSAS, while only 8 of the children showed moderate risk. The average score of OSA-18 was 50 (MB:57/NB:40), with 29 (19%) children showing moderate risk. Among these, 74% presented mouth breathing, 26% malocclusion, 61% dental caries, 35% tooth loss, 42% bruxism and 55% sucked ï¬nger or paciï¬er, and in the 14 (9%) with high risk, they were 100%, 75%, 58%, 50%, 67% and 67%, respectively. CONCLUSION: High frequencies of respiratory disorders with sleep repercussions associated with oral alterations were observed, reinforcing the correlation between mouth breathing and changes in stomatognathic system.
RESUMEN
INTRODUCTION: Multiple anatomic and functional risk factors contribute to Obstructive Sleep Apnea (OSA) in children, most of the screening tools only evaluate clinical symptoms. The aim was to describe the evaluation of the short orofacial myofunctional protocol (ShOM) in OSA children, and to analyze if the inclusion of orofacial myofunctional aspects would influence the screening sensitivity/specificity of the Sleep Clinical Record (SCR). METHODS: Children from Brazil and Italy with sleep disordered breathing were evaluated by full night polygraphy, the SCR and the ShOM. For the analysis of the correlations, we normalized the distribution of the children based on the percentiles of the Apnea and Hypopnea Index (AHI). The children were divided in: Group1: first percentile AHI up to25% (cut-off value: AHI≤1.9); Group 2: second percentile from 25% to 75% (cut-off values: 1.9ËAHI≤7.9); Group3: third percentile AHIË75% (cut = off value: AHIË7.9). The findings of SCR and ShOM were compared for each group. ROC curve of the sensitivity and specificity of OSA diagnosis were compared for SCR alone and the combined results of SCR plus ShOM. RESULTS: 86 children, 47 girls, 4-11 years, were included, 34 children were obese and 20 overweight. OSA severity and obesity showed a positive correlation (p = 0.04). Mean ShOM score was 5.64 ± 2.27, with a positive correlation to the SCR (p = 0.002). In Group1, the SCR showed more nasal obstruction, arched palate and OSAS score/positive Brouilette questionnaire and the ShOM scored more alterations to breathing mode, breathing type (p = 0.01) and lip competence. In Group 3, we found more tonsillar hypertrophy, Friedman tongue position alteration (p < 0.001), malocclusion and obesity at SCR and more alterations in tongue resting position, tongue deglutition position and malocclusion at ShOM. CONCLUSIONS: The myofuntional evaluation contributed to the screening of OSA in children, while alterations of the tongue (resting and deglutition position) were observed in children with the highest AHI percentile. The combination of SCR and ShOM improved the sensitivity and specificity for the identification of pediatric OSA when compared to SCR alone.

We proposed to compare the accuracy and effectiveness of digital breast tomosynthesis (DBT), plus digital or synthetic mammography, with digital mammography alone in women attending population-based breast cancer screenings. We performed a systematic review and included controlled studies comparing DBT with digital mammography for breast cancer screening. Search strategies were applied to the MEDLINE, Embase, LILACS, and CENTRAL databases. With moderate quality of evidence, in 1,000 screens, DBT plus digital mammography increased the overall and invasive breast cancer rates by 3 and 2 (RR 1.36, 95% CI 1.18 to 1.58 and RR 1.51, 95% CI 1.27 to 1.79, respectively). DBT plus synthetic mammography increased both overall and invasive breast cancer rates by 2 (RR 1.38, 95% CI 1.24 to 1.54 and RR 1.37, 95% CI 1.22 to 1.55, respectively). DBT did not improve recall, false positive and false negative rates. However due to heterogeneity the quality of evidence was low. For women attending population-based breast cancer screenings, DBT increases rates of overall and invasive breast cancer. There is no evidence with high or moderate quality showing that DBT compared with digital mammography decreases recall rates, as well as false positive and false negative rates.

OBJECTIVE: To apply the Sleep Clinical Record (SCR) to a sample of Brazilian children with sleep complaints, to compare the results with Italian children, and to identify variables that influence phenotype. METHODS: Brazilian and Italian children, 4-11 years of age and matched for age, gender, obesity, and apnea-hypopnea index and who presented with complaints related to sleep, were selected. The instrument used was the SCR, and the procedure used was full-night cardiorespiratory monitoring. RESULTS: The sample consisted of 51 Brazilian children and 102 Italian children. Brazilian children presented with oral breathing (55%), tonsillar hypertrophy (69%), Friedman palate position (88%), malocclusion (84%), and OSAS score (Brouilette questionnaire) (55%). The SCR among obese Brazilian children was higher as compared to that in nonobese subjects (obese, 10.84 vs nonobese, 9.13; p = 0.03). In the comparison between Brazilian and Italian children, the total Brazilian SCR was higher than the Italian SCR score (Brazilian SCR, 10.21 ± 7.56; Italian SCR, 8.95 ± 2.55; p = 0.002). The Italian SCR score was influenced by obesity, whereas the Brazilian SCR was influenced by others symptoms (daytime sleepiness, enuresis, nocturnal choking, headache, limb movements). CONCLUSION: Brazilian children with sleep-disordered breathing show a higher SCR score as compared to Italian children. Obesity and tonsillar hypertrophy, Friedman palate position alteration, and dental malocclusion further influenced the total SCR score among Brazilian children. This may be due to access difficulties in Brazil where children should have more assistance to obtain medical care.

RESUMO Objetivo Investigar as estruturas e funções orofaríngeas de uma população pediátrica com Síndrome de Down (SD) e apneia obstrutiva do sono (AOS) e correlacionar com o índice de apneia/hipopneia (IAH) e questionários do sono. Método 12 Crianças com SD e AOS, entre 4 e 12 anos, foram submetidas à polissonografia (PSG); questionários do sono, Pediatric Sleep Questionnaire (PSQ) e Obstructive Sleep Apnea-18 (OSA-18); e triagem fonoaudiológica por meio do Short Evaluation of Orofacial Myofunctional Protocol (ShOM). Resultados Verificou-se uma correlação positiva entre pontuações mais elevadas no ShOM e o índice de apneia hipopneia (IAH) e entre o ShOM e número de hipopneias. As alterações miofuncionais orofaciais observadas no grupo estudado foram: respiração oral, alteração no tônus e competência labial, na postura de língua em repouso e na deglutição e alteração oclusal. Verificou-se também, um risco aumentado para AOS conforme os questionários do sono, bem como presença de obesidade e sobrepeso, mas sem correlação com a gravidade da AOS. Conclusão Todas as crianças apresentaram alterações miofuncionais orofaciais, sendo que escores mais altos no ShOM, ou seja, um maior comprometimento miofuncional orofacial, estavam associados à maior gravidade de AOS, sugerindo que a avaliação miofuncional orofacial dentro de uma abordagem multidisciplinar pode auxiliar na identificação de fatores de risco para AOS em crianças com SD.
ABSTRACT Purpose To investigate oropharyngeal structures and functions in a pediatric population with Down Syndrome (DS) and obstructive sleep apnea (OSA) and to correlate with the apnea/hypopnea index (AHI) and sleep questionnaires. Methods 12 Children with DS and OSA, between the age of 4 and 12 years old, underwent polysomnography (PSG); sleep questionnaires, Pediatric Sleep Questionnaire (PSQ) and Obstructive Sleep Apnea-18 (OSA-18); and speech-language evaluation using the Short Evaluation of Orofacial Myofunctional Protocol (ShOM). Results There was a positive correlation between ShoM higher scores and the apnea-hypopnea index (AHI) and between ShoM and the number of hypopneas. The orofacial myofunctional alterations observed in the studied group were: oral breathing, alteration in lip tonus and competence, tongue posture at rest and in swallowing, and occlusal alteration. There was also an increased risk for OSA according to the sleep questionnaires, as well as the presence of obesity and overweight, but without correlation with the severity of OSA. Conclusion All DS children show alterations in orofacial characteristics, higher scores being associated to severe OSA. Orofacial myofunctional evaluation may help to identify different phenotypes in Down syndrome children with Obstructive sleep Apnea, enhancing the need for a multidisciplinary approach.
RESUMEN
Abstract Objective To measure the average time for the diagnosis and for the therapeutic prescription of Continuous Positive Airway Pressure (CPAP) at a hospital in Botucatu Medical School - State University São Paulo, UNESP. Method A retrospective observational study was carried out by collecting data from the electronic medical records of patients over 18-years of age, who had a diagnostic polysomnography testing scheduled between January and December 2017. Result Of the 347 patients eligible for the study, 94 (27.1%) missed follow-up and 103 (29.7%) had a referral for CPAP use. Until February 2021, only 37 (35.9%) of these patients had already acquired and were using the device, the remaining 66 (64.1%) were waiting or gave up the therapy. The mean value of the waiting time interval between the referral of the diagnostic test and its performance was equivalent to 197 days (6.5 months). The mean time between diagnostic polysomnography and CPAP prescription was 440-days (14.5-months), with a total mean time of 624 days (21-months). Conclusion As in other services, the diagnostic-therapeutic flow proved to be highly inefficient, with a long waiting period, difficult access to treatment and a high dropout rate. These findings highlight the need to establish new patient-centered strategies with measures that speed up the flow and facilitate access to CPAP, in order to reduce the morbidity and mortality associated with this condition. Level of evidence Level 3 - Non-randomized controlled cohort/follow-up study Recommendation B.
