Abstract Objective: To analyze the satisfaction of those responsible for adolescents with information received for the use of psychotropic drugs. Methods: Cross-sectional study carried out in a reference outpatient clinic in Brasília between 2017 and 2019. It involved 173 legal representatives of adolescents diagnosed with Mental and Behavioral Disorders using psychotropic drugs. In order to identify the level of satisfaction about the information received on psychotropic drugs, the Satisfaction with Information about Medicines Scale (SIMS) was used. Results: Most guardians were dissatisfied with the information received on psychotropic drugs (n=112; 64.7%). The dissatisfaction with information about potential problems of medication was the one that stood out the most (n=127; 73.4%) when compared to information about action and usage (n=89; 51.5%). Participants considered information on the impact of medication on the adolescent’s sexual life unsatisfactory or nonexistent. Conclusions: The parents’ satisfaction with the information received about psychotropic drugs was low. Participants showed dissatisfaction with the information about potential problems, especially related to the impact on the sexual life of their tutored.
摘要目的:分析青少年负责人对所收到的精神药物使用信息的满意度。方法:2017年至2019年间在巴西利亚的一家参考门诊进行的横断面研究。它涉及173名使用精神药物被诊断为精神和行为障碍的青少年的法律代表。为了确定对收到的精神药物信息的满意度,使用了药物信息满意度量表。结果:大多数监护人对收到的有关精神药物的信息不满意(n=112;64.7%)。与有关行动和使用的信息(n=89;51.5%)相比,对药物潜在问题的信息最不满意(n=127;73.4%)。参与者考虑了药物对青少年性行为影响的信息生活不能令人满意或根本不存在。结论:家长对所收到的精神药品信息的满意度较低。参与者对潜在问题的信息表示不满,尤其是与对辅导对象性生活的影响有关的信息。

Abstract Objective: To systematically establish whether there is an association between polymorphisms and avascular necrosis in patients with sickle cell disease. Data source: The review, conducted according to PRISMA guidelines and registered with PROSPERO, was based on research of studies in PubMed, SciELO, LILACS, BVS databases and in the gray literature (Google Scholar and Open Gray) published until June 2020. The STROBE initiative was used to analyze the articles’ quality. Data synthesis: Ten articles were selected from the databases and two were included through manual search, totaling 12 studies. All samples gathered 2,362 patients. According to STROBE, seven studies fully and/or partially covered more than 70% of the essential items and two studies reached less than 60%, with an overall variation of 86.4–54.5%. The results indicate that polymorphisms in the genes of the bone morphogenetic protein 6 (BMP6), Klotho (KL) and Annexin A2 (ANXA2) may be associated with osteonecrosis in the context of sickle cell disease. Six articles addressed the polymorphism in the MTHFR enzyme gene, but only one found a positive association. Polymorphisms associated with the DARC receptor, the ITGA4 gene, CD36 and thrombophilia protein genes were not associated in any of the studies. Conclusions: The results indicate that the polymorphisms in BMP6, Klotho and ANXA2 genes may be associated with avascular necrosis in patients with sickle cell disease. However, in order to confirm these genetic changes as risk factors, further studies with greater statistical power and methodological rigor are needed.
摘要目的:系统地确定镰状细胞病患者的多态性与缺血性坏死之间是否存在关联。数据来源:该综述根据PRISMA指南进行,并在PROSPERO注册,基于PubMed、SciELO、LILACS、BVS数据库和截至2020年6月发表的灰色文献(Google Scholar和Open gray)中的研究。STROBE倡议被用来分析文章的质量。数据综合:从数据库中选择10篇文章,通过手动搜索纳入2篇,共12项研究。所有样本采集了2362名患者。根据STROBE的数据,7项研究完全和/或部分覆盖了70%以上的基本项目,2项研究达到了60%以下,总体变异率为86.4–54.5%。结果表明,骨形态发生蛋白6(BMP6)、Klotho(KL)和膜联蛋白A2(ANXA2)基因的多态性可能与镰状细胞病背景下的骨坏死有关。六篇文章涉及MTHFR酶基因的多态性,但只有一篇发现了正相关。与DARC受体、ITGA4基因、CD36和血栓形成蛋白基因相关的多态性在任何研究中都没有关联。结论:BMP6、Klotho和ANXA2基因多态性可能与镰状细胞病患者的缺血性坏死有关。然而,为了确认这些基因变化是危险因素,还需要更大的统计能力和方法学严谨性的进一步研究。

Abstract Objective: To perform a systematic review in order to verify the association between full-term birth of small for gestational age (SGA) children and the outcomes in the development of oral language. Data source: Articles from MEDLINE/PubMed, Web of Science, Embase, Lilacs, SciELO and Cochrane Library databases were identified, selected and critically evaluated by two independent reviewers and a judge, blindly, without language restriction and publication period. The PRISMA tool was used, and original studies with a theme involving children born full-term and SGA were included, outcome related to aspects of oral language development, as well as the use of tests, scales and/or specific questionnaires for the investigation, whose methodology was described in full, with children as the target population. Data synthesis: The researchers included nine articles based on the eligibility criteria. Studies have shown that being born SGA can interfere in aspects related to language and reported greater chances of under performance in SGA children when compared to children with appropriate size for gestational age. It was observed that the different studies did not have a uniform design, and the objectives were quite diverse. Furthermore, few of them had as focus issues related to the assessment of language, as well as the variability of instruments used to investigate this domain. Conclusions: The effects of low weight for gestation age in full-term infants continue beyond the neonatal period and may impact on children’s performance, mainly with regard to oral language development.
摘要目的:对小胎龄儿(SGA)足月出生与口语发育的关系进行系统评价。数据来源:文章来自MEDLINE/PubMed、Web of Science、Embase、Lilacs、SciELO和Cochrane图书馆数据库,由两名独立审稿人和一名法官进行盲审、筛选和批判性评价,不受语言和出版期限的限制。使用了PRISMA工具,并纳入了涉及足月出生儿童和SGA的主题的原始研究,与口语发展各方面有关的结果,以及使用测试、量表和/或具体调查问卷进行调查,其方法以儿童为目标人群进行了全面描述。数据综合:研究人员根据入选标准纳入了9篇文章。研究表明,出生时身材矮小的儿童会在语言相关方面受到干扰,与胎龄合适的儿童相比,身材矮小的儿童表现不佳的可能性更大。据观察,不同的研究没有统一的设计,目标也很不同。此外,其中很少有与语言评估以及用于调查这一领域的工具的可变性有关的重点问题。结论:足月婴儿的低体重对胎龄的影响持续到新生儿期之后,并可能影响儿童的表现,主要是在口语发展方面。

Abstract Objective: To evaluate the quality of children’s menus in restaurants located in shopping malls. Methods: To select the sample, restaurants from 30% of shopping malls in each region of the city of São Paulo were included and, after considering only one restaurant per chain, the total was limited to 151 restaurants, 30.2% of which (n=35) presented a children’s menu. Data were collected through a form on Google Forms. Results: Of the restaurants with children’s menu, 60% (n=21) were conventional restaurants and 40% (n=14) takeaway/fast-food. The large number of chains present in most visited malls showed a democratization of the way of eating, with popular and accessible menus, regardless of social status. Most of the analyzed foods were cooked (41.5%). Most preparations did not use grease in their preparation and there was a notable lack of fruit and vegetables (FV) (4%). Sweet desserts were offered in 11.4% of the places and 20% included gifts with meals. Conclusions: The scarce offer of children’s menus, few options and low FV offer indicate the need for a new look at the development of children’s menus and a greater integration between the possibilities of restaurants and the expectations of parents and children, in the challenge of integrating the relationship between the supply of new foods that promote healthier habits and their consumption.
摘要目的:评价购物中心餐饮场所儿童菜单的质量。方法:为了选择样本,纳入了圣保罗市每个地区30%的购物中心的餐厅,在考虑每个连锁店只有一家餐厅后,总数限制在151家餐厅,其中30.2%(n=35)提供儿童菜单。数据是通过谷歌表单上的表格收集的。结果:在提供儿童菜单的餐厅中,60%(n=21)是传统餐厅,40%(n=14)是外卖/快餐。大多数购物中心的大量连锁店显示出饮食方式的民主化,无论社会地位如何,都有受欢迎和方便的菜单。大多数被分析的食物都是煮熟的(41.5%)。大多数制剂在制备过程中不使用油脂,并且明显缺乏水果和蔬菜(FV)(4%)。11.4%的地方提供甜甜点,20%的地方提供随餐礼物。结论:儿童菜单供应稀少,选择较少,FV供应较低,这表明需要对儿童菜单的发展进行新的审视,并在餐厅的可能性与父母和儿童的期望之间进行更大的整合,在整合促进健康习惯的新食品供应与消费之间的关系方面面临挑战。

ABSTRACT Objective: To assess thyroid function in very preterm or very low birth weight (VLBW) neonates by measuring combination levels of thyroid-stimulating hormone TSH and free T4 (FT4) Methods: Inclusion criteria were defined as all very preterm (gestational age <32 weeks) or VLBW (birth weight ≤1500g) neonates with initial Thyroid Function Test (TFT) who were admitted to the Neonatal Intense Care Unit (NICU) of Taleghani Hospital, Tabriz, Iran, from March 2015 to March 2016. Exclusion criteria were the absence of initial TFT with any major congenital anomaly. The primary value of TSH was evaluated at 3–5 days, and mean levels of TSH with FT4 were measured at 2, 4, and 8-weeks. Results: Ninety-five neonates with a mean gestational age of 29.5 weeks were included, and the mean levels of thyrotropin and FT4 at postnatal week two were 4.4mIU/L and 1.4ng/dL, respectively. Two of the patients had serum TSH concentration >25mIU/L that was considered as permanent primary hypothyroidism. Among nine hypothyroxinemia cases, two had elevated TSH levels (10.8±0.4mIU/L at the end of 8 weeks) and normal FT4 concentration, and were considered transient hypothyroidism. Seven cases had normal TSH levels (1.6±1.0mIU/L at 2 weeks, 3.5±2.8mIU/L at 8 weeks) and low FT4 concentrations. Conclusions: Combined venous TSH and FT4 concentration at the end of the first postnatal month can be an efficient approach for detecting neonatal hypothyroidism.
摘要目的:通过测量促甲状腺激素TSH和游离T4(FT4)的联合水平,评估极早产或极低出生体重(VLBW)新生儿的甲状腺功能(10.8±0.4mIU/L)和正常FT4浓度,被认为是短暂性甲状腺功能减退。7例TSH水平正常(2周时为1.6±1.0mIU/L,8周时为3.5±2.8mIU/L),FT4浓度较低。结论:出生后第一个月末静脉TSH和FT4浓度联合检测是检测新生儿甲状腺功能减退症的有效方法。

ABSTRACT Objective: The main aim of this study was to evaluate the performance of a platform designed for pediatricians to screen amblyopia using a smartphone. Methods: The medical records of consecutive children who received visual screening using a smartphone platform were retrospectively reviewed. The smartphone was used with a flash concentrator case and a software for capturing images of both eyes simultaneously by a photorefraction mechanism. The platform performance was compared to the comprehensive ophthalmological examination, which is considered the gold standard for detecting amblyopia. Sensitivity, specificity, positive predictive value, and negative predictive value of the software in detecting amblyopia risk factors were calculated. Results: A total of 157 children were included, with a mean age of 6.0±.5 years (range 5–7). In 94% of the cases, the software was able to analyze the images and release a result, determining whether or not the child presented with amblyopia risk factors. Compared to the ophthalmological examination, the smartphone platform sensitivity in detecting amblyopia risk factors was 84%, the specificity was 74%, the positive predictive value was 86%, and the negative predictive value was 70%. Conclusions: The sensitivity and specificity of the smartphone photoscreening platform to detect amblyopia risk factors were within the range of traditional instrument-based vision screening technology. A smartphone photorefraction platform appears to be a promising cost-effective alternative to assist pediatricians and minimize obstacles to vision screening and amblyopia detection. Future studies are needed to gather additional comparative data.
摘要目的:本研究的主要目的是评估儿科医生使用智能手机筛查弱视的平台的性能。方法:回顾性分析连续使用智能手机平台进行视觉筛查的儿童的医疗记录。该智能手机配备了一个闪光灯集中器外壳和一个通过光分解机制同时捕捉双眼图像的软件。该平台的性能与眼科综合检查进行了比较,后者被认为是检测弱视的黄金标准。计算软件检测弱视危险因素的敏感性、特异性、阳性预测值和阴性预测值。结果:共纳入157名儿童,平均年龄为6.0±.5岁(5-7岁)。在94%的病例中,该软件能够分析图像并发布结果,以确定儿童是否存在弱视风险因素。与眼科检查相比,智能手机平台检测弱视危险因素的敏感性为84%,特异性为74%,阳性预测值为86%,阴性预测值为70%。结论:智能手机光电筛查平台检测弱视危险因素的灵敏度和特异性在传统仪器视觉筛查技术的范围内。智能手机照片分割平台似乎是一种极具成本效益的替代方案,可以帮助儿科医生,最大限度地减少视力筛查和弱视检测的障碍。未来的研究需要收集更多的比较数据。

ABSTRACT Objective: To analyze the socioeconomic, demographic, environmental, reproductive, behavioral, and health-care factors associated with preterm birth. Methods: Case-control study, with case group composed of preterm infants and the control group by full term live births. Each case was paired with two controls according to sex and date of birth. Interviews were carried out with the mothers, as well as analysis of medical records. A logistic regression model was used for data analysis following the hierarchical order of entry of the blocks. Results: 221 live births were allocated in the case group and 442 in the control group. After analysis adjusted for other factors under study, the highest chances of prematurity were associated with being the first child (OR 1.96; 95%CI 1.34–2.86; p=0.001); mothers with the highest income (OR 2.08; 95%CI 1.41–3.08; p<0.001), mothers with previous preterm births (OR 3.98; 95%CI 2.04–7.79; p<0.001), mothers that suffered violence during pregnancy (OR 2.50; 95%CI 1.31–4.78; p=0.005) and underwent cesarean section (OR 2.35; 95%CI 1.63–3.38; p<0.001). Live births to mothers who had more than six prenatal consultations had a lower risk of prematurity (OR 0.39; 95%CI 0.26–0.58; p<0.001). Conclusions: The factors associated with a higher chance of prematurity were: higher family income, previous preterm child, primiparity, violence against pregnant women and cesarean section. Having attended more than six prenatal visits was associated with a lower chance of premature birth. Violence against pregnant women showed a strong and consistent association, remaining in all final models, and should serve as an alert for the population and professionals.
摘要目的:分析与早产相关的社会经济、人口、环境、生殖、行为和医疗因素。方法:病例对照研究,病例组由早产儿组成,对照组由足月活产组成。根据性别和出生日期,每个病例与两个对照组配对。对这些母亲进行了访谈,并对医疗记录进行了分析。逻辑回归模型用于数据分析,遵循区块进入的层次顺序。结果:病例组221例,对照组442例。在对研究中的其他因素进行分析调整后,早产的最高几率与生第一个孩子有关(OR 1.96;95%CI 1.34–2.86;p=0.001);收入最高的母亲(OR 2.08;95%CI 1.41–3.08;p<0.001),有早产病史的母亲(OR3.98;95%CI 2.04–7.79;p<001),妊娠期间遭受暴力的母亲(OR 2.50;95%CI 1.31–4.78;p=0.005)和接受剖宫产手术的母亲(OR2.35;95%CI 1.63–3.38;p<0.001)。接受过六次以上产前咨询的母亲活产早产风险较低(OR 0.39;95%CI 0.26–0.58;p<0.01),既往早产、初产妇、暴力侵害孕妇和剖宫产。参加过六次以上的产前检查与早产几率较低有关。对孕妇的暴力行为表现出强烈而一致的关联,在所有最终模型中都存在,应该成为民众和专业人员的警报。

ABSTRACT Objective: To describe then experience of implementing routine teleconsultations in respiratory physiotherapy at a reference center for Cystic Fibrosis (CF) in Rio de Janeiro / Brazil, during the COVID-19 pandemic. Methods: Cross-sectional, descriptive, study with children and adolescents with CF. The sample was divided between participants and those who did not participate in the teleconsultations. The teleconsultations were multidisciplinary and carried out by videoconference or telephone, depending on the patient’s availability. The sequence of care provided by the team was organized together with the professionals, so that everyone could carry out individual and sequential teleconsultations. Physiotherapy appointments were divided into two segments: teleconsultation and telemonitoring. Demographic and clinical data were collected. Results: Among the 184 patients assisted in the center, 153 (83.2%) participated in the teleservices and, of these, 33 (21.6%) required telemonitoring; 31 (16.8%) patients did not participate in the teleconsultations for not answering the calls. There was no statistical difference between the group that participated or not in teleservices, nor among those who participated in teleconsultations and telemonitoring. The mean age of the studied population was 7.0±0.4 years. Regarding the CFTR gene mutation, 64.7% had at least one F508del allele and 30.9% of the sample had no pathogens in the sputum test. Conclusions: Most participants with CF participated in teleconsultations, highlighting the importance of remote assistance activities during the COVID-19 pandemic period. This strategy was considered as positive, and it may become permanent in the care of patients with CF.
摘要目的:描述新冠肺炎大流行期间,在巴西里约热内卢囊性纤维化(CF)参考中心实施呼吸理疗常规远程咨询的经验。方法:对患有CF的儿童和青少年进行横断面、描述性研究。样本分为参与者和未参与远程咨询的参与者。远程会诊是多学科的,根据患者的可用性通过视频会议或电话进行。团队提供的护理顺序是与专业人员一起组织的,这样每个人都可以进行单独和顺序的远程咨询。理疗预约分为两个部分:远程咨询和远程监测。收集人口统计学和临床数据。结果:在中心协助的184名患者中,153人(83.2%)参与了远程服务,其中33人(21.6%)需要远程监护;31名(16.8%)患者因未接听电话而未参加远程会诊。参与或不参与远程服务的组之间,以及参与远程咨询和远程监测的组之间都没有统计差异。研究人群的平均年龄为7.0±0.4岁。关于CFTR基因突变,64.7%的样本至少有一个F508del等位基因,30.9%的样本在痰检中没有病原体。结论:大多数CF参与者参加了远程咨询,突出了在新冠肺炎大流行期间远程援助活动的重要性。这种策略被认为是积极的,在CF患者的护理中可能会成为永久性的。

Abstract Objective: To describe clinical and epidemiological aspects of children and adolescents infected with the SARS-CoV-2 in the Municipality of Taubaté, SP, from March to November 2020. Methods: Cross-sectional study with secondary data obtained from the Epidemiological Surveillance System about confirmed cases in city residents and from medical records of patients who were treated in hospitals in Taubaté, aged between 0 and 19 years. Chi-square and Student’s t tests were used for comparisons. Results: 677 cases in the studied age range were reported during the study period, corresponding to 10.1% of cases reported in the municipality. The rapid antibody test was the most used to confirm infection, followed by RT-PCR and serology. Symptoms were described in 57.7% of the cases, mainly fever and cough. Diarrhea was associated with age below 4 years, while fever, cough, headache, odynophagia, ageusia, anosmia, myalgia, and dyspnea were associated with an age ranging from 10 to 19 years. In the study period, there were no deaths from COVID-19 of residents of the municipality in the age group from 0 to 19 years. Conclusions: The study was able to identify the proportion of involvement of COVID-19 in children and adolescents in the city, and the disease had a mild evolution. The main symptoms were fever and cough, but mainly diarrhea in younger children, and headache, odynophagia, anosmia, ageusia, and myalgia in adolescents.

Abstract Objective: To analyze the association between the pattern of sedentary time (bouts and breaks) with academic performance, with an emphasis on the mediating role of self-concept. Methods: Participants in the cross-sectional study were 394 adolescents (208 girls), aged 10–14 years, from sixth grade from Londrina, Paraná, Brazil. The sedentary time pattern was measured through accelerometry. Definitions: sedentary bouts — uninterrupted periods of sedentary behavior; breaks — non-sedentary period between two sedentary bouts. The self-concept was estimated using the Piers-Harris II Inventory. Academic performance was obtained by school grades. Results: Short sedentary bouts were associated with higher academic performance in boys (1–4 minutes: β=0.035, p=0.007) and girls (1–4 minutes: β=0.031, p=0.014; 5–14 minutes: β=0.054, p=0.001). Long bouts (30 minutes) were associated with lower academic performance in boys (β=-0.023; p=0.011) and girls (β=-0.032; p<0.001). For girls, total and intellectual self-concept mediated the association between all sedentary pattern and academic performance (bouts 1–4 minutes [total: 39% and intellectual: 42.8%]; bouts 5–14 minutes [total: 21.5% and intellectual: 35.4%]; bouts ≥30 minutes [total: 22.6% and intellectual: 32.3%]; and breaks [total: 38.9% and intellectual: 40.7%]). For boys, the total (56.4%) and intellectual (82.9%) self-concept mediated only the association between bouts of 5–14 minute and academic performance. Conclusions: The pattern of sedentary time is associated with academic performance in adolescents and this association is mediated by self-concept, especially in girls.
摘要目的:分析久坐时间(间歇)模式与学习成绩之间的关系,强调自我概念的中介作用。方法:横断面研究的参与者是来自巴西巴拉那州龙德里纳的394名10-14岁的六年级青少年(208名女孩)。久坐时间模式是通过加速度计测量的。定义:久坐不动——不间断的久坐行为;休息时间——两次久坐之间的非久坐时间。自我概念使用皮尔斯·哈里斯II量表进行评估。学习成绩是通过学校成绩来衡量的。结果:男孩(1-4分钟:β=0.035,p=0.007)和女孩(1-4分钟,β=0.031,p=0.014;5-14分钟:β0.054,p=0.001)久坐不动与学习成绩较高有关。男孩(β=0.023;p=0.011)和女孩,总的和智力的自我概念介导了所有久坐模式和学习成绩之间的联系(发作1-4分钟[总计:39%,智力:42.8%];发作5-14分钟[合计:21.5%,智力:35.4%];发作≥30分钟[总计:22.6%,智力:32.3%];休息[总计:38.9%,智力:40.7%]),总自我概念(56.4%)和智力自我概念(82.9%)仅在5-14分钟的发作与学习成绩之间起中介作用。结论:青少年久坐时间模式与学习成绩有关,这种联系是由自我概念介导的,尤其是女孩。
