Restauração em resina composta semidireta em dente posterior: relato de caso / Semi-direct composite restoration in posterior toth: a case report

A escolha da técnica restauradora desempenha papel fundamental na eficácia e duração de um tratamento reabilitador. O objetivo deste relato de caso foi descrever a utilização da técnica semidireta para a confecção de uma restauração em resina composta em um primeiro molar inferior. A paciente apresentava uma restauração insatisfatória no dente 36, que necessitava ser substituída devido à infiltração por cárie. Optou-se pela técnica semidireta devido à amplitude da cavidade, que envolvia estruturas de suporte, e pela combinação das vantagens das abordagens direta e indireta. O procedimento envolveu a remoção de tecido cariado, a aplicação de hidróxido de cálcio pasta, seguida da aplicação de uma fina camada de ionômero de vidro e, posteriormente, resina fluída para realizar o selamento dentinário. O preparo foi realizado seguindo os princípios necessários. O elemento em questão foi moldado com silicone de adição e o arco antagonista, com alginato. Ambos modelos foram vertidos com silicone para modelos semirrígidos e montados em oclusor de peças de brinquedo. A restauração semidireta foi confeccionada em resina composta Filtek Z350 XT, respeitando a anatomia do dente 36. Pigmentos foram utilizados para aprimorar detalhes estéticos. Após acabamento e polimento, a peça foi condicionada e cimentada com cimento dual Relyx Ultimate. Pode-se concluir que a abordagem restauradora por meio da técnica semidireta construída em modelo semirrígido é uma opção terapêutica conservadora e vantajosa para dentes com extensa destruição coronária. Essa técnica possibilita a restauração de forma eficaz, garantindo tanto a estética quanto a função adequada do dente afetado(AU)

The choice of restorative technique plays a fundamental role in the effectiveness and duration of rehabilitation treatment. The objective of this case report was to describe the use of the semi-direct technique to create a composite resin restoration in a lower first molar. The patient had an unsatisfactory restoration on tooth 36, which needed to be replaced due to cavity infiltration. The semi-direct technique was chosen due to the amplitude of the cavity, which involved support structures, and the combination of advantages of the direct and indirect approaches. The procedure involved the removal of carious tissue, and the application of calcium hydroxide paste, followed by the application of a thin layer of glass ionomer and, subsequently, fluid resin to seal the dentin. The preparation was carried out following the necessary principles. The element in question was molded with addition silicone and the antagonist arch was molded with alginate. Both models were poured with silicone for semi-rigid models and mounted on toy parts occluders. The semi-direct restoration was made in Filtek Z350 XT composite resin, respecting the anatomy of tooth 36. Pigments were used to improve aesthetic details. After finishing and polishing, the piece was conditioned and cemented with Relyx Ultimate dual cement. It can be concluded that the restorative approach using the semi-direct technique built on a semi-rigid model is a conservative and advantageous therapeutic option for teeth with extensive coronal destruction. This technique allows for effective restoration, ensuring both the aesthetics and adequate function of the affected tooth(AU)

A contribuição do pensamento de Paulo Freire para a Vigilância Popular em Saúde / The contribution of Paulo Freire's thought to Popular Health Surveillance

Resumo Paulo Freire pensava a Educação Popular (EP) como um processo emancipatório, por meio da problematização e agir crítico como dimensões da existência humana. A partir de suas contribuições aos campos da Educação e da Saúde, este texto tem como objetivo realizar uma revisão narrativa de literatura sobre as articulações das ideias de Paulo Freire com as ações de Vigilância Popular em Saúde (VPS). O texto apresenta como a contribuição de Paulo Freire e da Educação Popular em Saúde inspirou a construção de uma Vigilância Popular em Saúde, que busca promover a transformação da realidade local frente às situações de violações de direitos e na defesa da vida. Dessa maneira, experiências dos territórios e das populações em situação de vulnerabilidade, na maioria das vezes, lançam mão de estratégias pedagógicas da Educação Popular para se constituírem como práticas de VPS. É no território que a Educação Popular em Saúde se torna fundamental para o estímulo à transformação da percepção dos indivíduos, problematizando sua realidade. A promoção de uma práxis acerca da "situação limite" no cotidiano dos atores sociais permite um diagnóstico da realidade, baseado na informação científica em diálogo com a cultura e a organização popular, como possibilidade de construção de "inéditos viáveis".

Abstract Paulo Freire considered Popular Education (PE) as an emancipatory process, through debate and critical action, as a dimension of human existence. This text aims to conduct a narrative literature review on the articulations of Paulo Freire's ideas with Popular Health Surveillance (PHS) actions based on his contributions to Education and Health. The text presents how the contributions of Paulo Freire and Popular Health Education inspired the construction of Popular Health Surveillance, which seeks to promote the transformation of local reality in the face of rights violations and advocate for life. Thus, experiences from vulnerable territories and populations often use Popular Education pedagogical strategies to establish PHS practices. Popular Health Education becomes crucial in the territory to stimulate the transformation of individual perception and discuss their reality. Promoting a praxis about the "critical situation" in the daily lives of social stakeholders allows diagnosing reality based on scientific information in dialogue with culture and popular organization as a possibility of building the "viable unprecedented".

Desigualdades sociais no diagnóstico do câncer do colo do útero no Brasil: um estudo de base hospitalar / Social inequalities in the diagnosis of cervical cancer in Brazil: a hospital-based study

Resumo O estudo visa analisar a prevalência de estadiamento avançado ao diagnóstico do câncer do colo do útero e sua associação com indicadores individuais e contextuais socioeconômicos e de oferta de serviços de saúde no Brasil. Estudo transversal, realizado com casos de câncer do colo do útero em mulheres de 18 a 99 anos, no período de 2006 a 2015, extraídos do Integrador de Registros Hospitalares de Câncer. Variáveis contextuais foram coletadas no Atlas do Desenvolvimento Humano, no Cadastro Nacional de Estabelecimentos de Saúde e no Sistema de Informações Ambulatoriais. Usou-se o modelo de regressão de Poisson multinível com intercepto aleatório. A prevalência de diagnóstico em estádio avançado foi de 48,4%, apresentando associação com idades mais avançadas (RP 1,06; IC 1,01-1,10), raça/cor da pele preta, parda e indígena (RP 1,04; IC 1,01-1,07), menores níveis de escolaridade (RP 1,28; IC 1,16-1,40), ausência de parceiro conjugal (RP 1,10; IC 1,07-1,13), encaminhamento do tipo público ao serviço de saúde (RP 1,07; IC 1,03-1,11) e menor taxa de realização de exame citopatológico (RP 1,08; IC 1,01-1,14). Os resultados reforçam a necessidade de melhorias no programa nacional de prevenção do câncer do colo do útero em áreas com baixa cobertura da citologia oncótica.

Abstract The scope of this study is to analyze the prevalence of advanced stage diagnosis of cervical cancer and its association with individual and contextual socioeconomic and healthcare service indicators in Brazil. A cross-sectional study was conducted using cervical cancer cases in women aged 18 to 99 years, from 2006 to 2015, extracted from the Hospital Cancer Registry (HCR) Integrator. Contextual variables were collected from the Atlas of Human Development in Brazil; the National Registry of Health Institutions (NRHI); and the Outpatient Information System. Multilevel Poisson Regression with random intercept was used. The prevalence of advanced stage diagnosis was 48.4%, revealing an association with older age groups (PR 1.06; CI 1.01-1.10), black, brown, and indigenous race/skin color (PR 1.04; CI 1.01-1.07), lower levels of schooling (PR 1.28; CI 1.16-1.40), no marital partner (PR 1.10; CI 1.07-1.13), public referral to the health service (PR 1.07; CI 1.03-1.11), and lower rates of cytological examination (PR 1.08; CI 1.01-1.14). The results reinforce the need for improvements in the national cervical cancer prevention program in areas with low coverage of oncotic cytology.

Association between the environment for physical activity in public schools and childhood obesity: a view in the light of complex systems / Associação entre ambiente para atividade física em escolas públicas e obesidade infantil: um olhar à luz de sistemas complexos

Abstract This article aims to analyse the relationship between physical activity (PA) environment at schools, sex, age, and obesity in children, using a network approach. This is a cross-sectional study, with 1,200 children (8.1±1.0 years old) from eight public schools in the same municipality. Weight and height measurements were assessed to calculate the Body Mass Index (BMI) and classified as healthier weight or overweight. To assess the PA environment at school, a interview with the school´s manager was conducted. The association between the PA environment at school and obesity was tested using a Network Analysis performed on the Jasp software. Positive associations between BMI and Physical Education classes (0.847), physical education teacher (0.349), break duration (0.564), and indoor sports court (0.662) were observed. Negative associations were seen with sex (-0.212) age (-0.387), extracurricular PA (-0.492), and playground (-0.557). Additionally, the centrality indicators highlighted extracurricular PA (1.789) as the variables with the highest betweenness values, and BMI with the highest closeness (2.239) and strength (1.230) values. Extracurricular PA and the presence of playgrounds in school´s environment are associated with healthier weight in low-income children.

Resumo O objetivo deste artigo é analisar a relação entre ambiente de atividade física (AF) nas escolas, sexo, idade e obesidade em crianças, usando uma abordagem de rede. Trata-se de um estudo transversal com 1.200 crianças (8,1±1,0 anos) de oito escolas públicas do mesmo município. Peso e estatura foram avaliadas para cálculo do Índice de Massa Corporal (IMC) e classificadas como peso saudável ou sobrepeso. Para avaliar o ambiente de AF na escola, foi aplicado um questionário por meio de entrevista com o gestor da escola. A associação entre o ambiente de AF na escola e a obesidade foi testada por meio Análise de Redes realizada no software Jasp. Foram observadas associações positivas entre o IMC e as aulas de Educação Física (0,847), professor de educação física (0,349), duração do intervalo (0,564) e quadra poliesportiva (0,662). Associações negativas foram observadas com sexo (-0,212), idade (-0,387), AF extracurricular (-0,492) e playground (-0,557). Adicionalmente, os indicadores de centralidade destacaram a AF extracurricular (1,789) como a variável com o maior valor de intermediação, e o IMC com o maior valor de proximidade (2,239) e força (1,230). A AF extracurricular e a presença de playgrounds no ambiente escolar estão associadas a um peso mais saudável em crianças de baixa renda.

Outcomes of ablative therapy and radical treatment for prostate cancer: a systematic review and meta-analysis

ABSTRACT Purpose: To compare biochemical recurrence, sexual potency and urinary continence outcomes of ablative therapy and radical treatment (radical prostatectomy or radiotherapy with androgen deprivation therapy). Material and methods: A systematic review and meta-analysis followed the PRISMA guidelines were performed. We searched MEDLINE/PubMed. Biochemical recurrence at three and five years; incontinence rate (patients who used one pad or more) and erectile dysfunction rate at 12 and 36 months (patients who did not have sufficient erection to achieve sexual intercourse) were evaluated. The Mantel-Haenszel method was applied to estimate the pooled risk difference (RD) in the individual studies for categorical variables. All results were presented as 95% confidence intervals (95%CI). Random effects models were used regardless of the level of heterogeneity (I²). (PROSPERO CRD42022296998). Results: Eight studies comprising 2,677 men with prostate cancer were included. There was no difference in biochemical recurrence between ablative and radical treatments. We observed the same biochemical recurrence between ablative therapy and radical treatment within five years (19.3% vs. 16.8%, respectively; RD 0.07; 95%CI=-0.05, 0.19; I2=68.2%; P=0.08) and continence rate at 12 months (9.2% vs. 31.8%, respectively; RD −0.13; 95%CI, −0.27, 0.01; I2=89%; P=0.32). When focal treatment was analyzed alone, two studies with 582 patients found higher erectile function at 12 months in the ablative therapy group than in the radical treatment (88.9% vs. 30.8%, respectively; RD −0.45; 95%CI −0.84, −0.05; I2=93%; P=0.03). Conclusion: Biochemical recurrence and urinary continence outcomes of ablative therapy and radical treatment were similar. Ablative therapy appears to have a high rate of sexual potency.

Surgical treatment for severe pediatric tracheobronchomalacia: the 20-year experience of a single center

Abstract Objective: In children with tracheobronchomalacia, surgical management should be reserved for the most severe cases and be specific to the type and location of tracheobronchomalacia. The goal of this study is to describe the presentation and outcomes of children with severe tracheobronchomalacia undergoing surgery. Methods: Retrospective case series of 20 children operated for severe tracheobronchomalacia at a tertiary hospital from 2003 to 2023. Data were collected on symptoms age at diagnosis, associated comorbidities, previous surgery, age at surgery, operative approach, time of follow-up, and outcome. Surgical success was defined as symptom improvement. Results: The most frequent symptoms of severe tracheobronchomalacia were stridor (50 %), cyanosis (50 %), and recurrent respiratory infections (45 %). All patients had one or more underlying conditions, most commonly esophageal atresia (40 %) and prematurity (35 %). Bronchoscopy were performed in all patients. Based on etiology, patients underwent the following procedures: anterior aortopexy (n = 15/75 %), posterior tracheopexy (n = 4/20 %), and/or posterior descending aortopexy (n = 4/20 %). Three patients underwent anterior aortopexy and posterior tracheopexy procedures. After a median follow-up of 12 months, 16 patients (80 %) had improvement in respiratory symptoms. Decannulation was achieved in three (37.5 %) out of eight patients with previous tracheotomy. The presence of dying spells at diagnosis was associated with surgical failure. Conclusions: Isolated or combined surgical procedures improved respiratory symptoms in 80 % of children with severe tracheobronchomalacia. The choice of procedure should be individualized and guided by etiology: anterior aortopexy for anterior compression, posterior tracheopexy for membranous intrusion, and posterior descending aortopexy for left bronchus obstruction.

Reconstrução mamária: Experiência de 10 anos / Breast reconstruction: 10 years experience

Introdução: A reconstrução mamária pós-tratamento cirúrgico do câncer de mama (um dos principais cânceres que acometem as mulheres) tem sido progressivamente mais indicada, haja vista o benefício da recuperação psicológica e da qualidade de vida, seja utilizando implantes e/ou tecidos autólogos. O presente trabalho visa demonstrar a experiência da equipe, discutir técnicas operatórias e complicações em relação aos dados da literatura mundial, além de verificar a aplicabilidade da técnica na prática clínica da equipe. Método: Estudo observacional retrospectivo desenvolvido em hospital universitário em Juiz de Fora a partir da revisão de prontuários de pacientes submetidas a mastectomia com reconstrução mamária entre 2010 e 2020. Resultados: Das 860 mamas abordadas, 84% foram imediatas à cirurgia oncológica e 16% foram tardias; o principal acesso ao tecido mamário foi a incisão de Stewart, seguido de incisões inframamárias estendidas, periareolares e T invertido; quanto às técnicas reconstrutoras, destaca-se 35% dos casos com retalho com músculo grande dorsal, 25% com prótese pré-peitoral, 20% com retalho miocutâneo transverso do músculo reto abdominal e 10% com retalho muscular local. As complicações mais incidentes foram deiscência de sítio cirúrgico, seguida de necrose cutânea, seroma, infecção de sítio cirúrgico e hematoma, além de outros menos comuns como dor crônica e ruptura de prótese após mamografia. Conclusão: A reconstrução mamária pós-mastectomia é indispensável para a recuperação física e emocional da mulher, sendo as técnicas utilizadas nos últimos dez anos consistentes, confiáveis, de baixa morbidade e com ótimos resultados estéticos quando bem indicadas.

Introduction: Breast reconstruction after surgical treatment for breast cancer (one of the main cancers that affect women) has been progressively more recommended, given the benefits of psychological recovery and quality of life, whether using implants and/or autologous tissues. The present work aims to demonstrate the team's experience, and discuss operative techniques and complications concerning data from the world literature, in addition to verifying the applicability of the technique in the team's clinical practice. Method: Retrospective observational study developed at a university hospital in Juiz de Fora based on a review of medical records of patients who underwent mastectomy with breast reconstruction between 2010 and 2020. Results: Of the 860 breasts treated, 84% underwent immediate oncological surgery and 16% were late; the main access to the breast tissue was the Stewart incision, followed by extended inframammary, periareolar, and inverted T incisions; regarding reconstructive techniques, 35% of cases used a latissimus dorsi muscle flap, 25% used a prepectoral prosthesis, 20% used a transverse rectus abdominis myocutaneous flap and 10% used a local muscle flap. The most common complications were surgical site dehiscence, followed by skin necrosis, seroma, surgical site infection, and hematoma, in addition to other less common complications such as chronic pain and prosthesis rupture after mammography. Conclusion: Postmastectomy breast reconstruction is essential for a woman's physical and emotional recovery, with the techniques used in the last ten years being consistent, reliable, with low morbidity, and with excellent aesthetic results when correctly indicated.

Reconstrução da região superior do dorso com retalho musculocutâneo do trapézio em V-Y baseado na artéria dorsal da escápula / Reconstruction of the upper region of the back with a V-Y trapezius musculocutaneous flap based on the dorsal artery of the scapula

Introdução: Defeitos na região superior do dorso geralmente são de difícil tratamento, especialmente nos casos de exposição de vértebras, meninge ou material de síntese. O fechamento primário com retalho muscular ou musculocutâneo é a melhor escolha, mas a área doadora para tratar grandes defeitos pode requerer enxertia. A preservação da artéria dorsal da escápula parece assegurar um território cutâneo maior do que o do retalho musculocutâneo do trapézio clássico baseado apenas na artéria cervical transversa. Método: Foi concebida uma ampla ilha triangular de pele sobre o músculo trapézio baseado na artéria dorsal da escápula com transferência por movimento pendular e um procedimento tipo V-Y em cinco pacientes após a extirpação de tumores malignos. Resultados: Os defeitos e as áreas doadoras foram fechados primariamente com total viabilidade dos retalhos e não foram observadas complicações além da ocorrência de seroma. Conclusão: O retalho musculocutâneo do trapézio baseado na artéria dorsal da escápula oferece segurança no tratamento de exposição óssea na região superior do dorso.

Introduction: Defects in the upper region of the back are generally difficult to treat, especially in cases of exposure of vertebrae, meninges, or synthetic material. Primary closure with a muscular or musculocutaneous flap is the best choice, but the donor area to treat large defects may require grafting. Preservation of the dorsal artery of the scapula appears to ensure a larger cutaneous territory than that of the classic trapezius musculocutaneous flap based only on the transverse cervical artery. Method: A wide triangular island of skin was designed over the trapezius muscle based on the dorsal scapular artery with pendulum transfer and a V-Y type procedure in five patients after the extirpation of malignant tumors. Results: The defects and donor areas were closed primarily with full viability of the flaps and no complications were observed other than the occurrence of seroma. Conclusion: The trapezius musculocutaneous flap based on the dorsal artery of the scapula offers safety in the treatment of bone exposure in the upper back region.

Screening of essential oils against oxacillin - resistant Staphylococcus aureus strains isolated from bovine mastitis / Screening de aceites esenciales frente a Staphylococcus aureus oxacilino - resistentes extraidos de aislados de mastitis bovina

Bovine mastitis is a disease wi th far - reaching consequences for the dairy industry. Staphylococcus aureus is a pathogen that is especially resistant to antibiotics. The objective of this study was to evaluate the antimicrobial activity of the essential oils Lippia citriodora (Lam.), Thy mus vulgaris (L), and a mixture of the essential oils Lippia citriodora and Thymus vulgaris (50/50 v/v), against isolates of oxacillin - resistant Staphylococcus aureus (n=15) of positive cases of bovine mastitis. For the statistical analysis, the IBM SPSS s tatistical package was used. The mixture of essential oils ( Lippia citriodora and Thymus vulgaris (50/50 v/v)) obtained the most significant antimicrobial activity in relation to pure essential oils. It is therefore concluded that the mixture of these oils boosts their antimicrobial activity ( p <0.05). The minimum inhibitory and bactericidal concentration of this mixture for the total isolations was 12 µL/L and 25 µL/mL, respectively.

O Treinamento Resistido Atenua a Remodelação Cardíaca Induzida por uma Dieta Hiperlipídica em Roedores: Uma Revisão Sistemática / Resistance Exercise Training Mitigates Cardiac Remodeling Induced by a High-Fat Diet in Rodents: A Systematic Review

Resumo Fundamento A obesidade está associada ao desenvolvimento de doenças cardiovasculares e constitui um grave problema de saúde pública. Em modelos animais, a alimentação com uma dieta hiperlipídica (DH) compromete a estrutura e a função cardíaca e promove estresse oxidativo e apoptose. O treinamento resistido (TR), entretanto, tem sido recomendado como coadjuvante no tratamento de doenças cardiometabólicas, incluindo a obesidade, porque aumenta o gasto energético e estimula a lipólise. Objetivo Na presente revisão sistemática, nosso objetivo foi avaliar os benefícios do TR no coração de ratos e camundongos alimentados com DH. Métodos Foram identificados estudos originais por meio de busca nas bases de dados PubMed, Scopus e Embase de dezembro de 2007 a dezembro de 2022. O presente estudo foi conduzido de acordo com os critérios estabelecidos pelo PRISMA e registrado no PROSPERO (CRD42022369217). O risco de viés e a qualidade metodológica foram avaliados pelo SYRCLE e CAMARADES, respectivamente. Os estudos elegíveis incluíram artigos originais publicados em inglês que avaliaram desfechos cardíacos em roedores submetidos a mais de 4 semanas de TR e controlados por um grupo controle sedentário alimentado com DH (n = 5). Resultados Os resultados mostraram que o TR atenua o estresse oxidativo cardíaco, a inflamação e o estresse do retículo endoplasmático. Também modifica a atividade de marcadores de remodelamento estrutural, apesar de não alterar parâmetros biométricos, parâmetros histomorfométricos ou a função contrátil dos cardiomiócitos. Conclusão Nossos resultados indicam que o TR parcialmente neutraliza o remodelamento cardíaco adverso induzido pela DH, aumentando a atividade dos marcadores de remodelamento estrutural; elevando a biogênese mitocondrial; reduzindo o estresse oxidativo, marcadores inflamatórios e estresse do retículo endoplasmático; e melhorando os parâmetros hemodinâmicos, antropométricos e metabólicos.

Abstract Background Obesity is associated with the development of cardiovascular diseases and is a serious public health problem. In animal models, high-fat diet (HFD) feeding impairs cardiac structure and function and promotes oxidative stress and apoptosis. Resistance exercise training (RT), however, has been recommended as coadjutant in the treatment of cardiometabolic diseases, including obesity, because it increases energy expenditure and stimulates lipolysis. Objective In this systematic review, we aimed to assess the benefits of RT on the heart of rats and mice fed HFD. Methods Original studies were identified by searching PubMed, Scopus, and Embase databases from December 2007 to December 2022. This study was conducted in accordance with the criteria established by PRISMA and registered in PROSPERO (CRD42022369217). The risk of bias and methodological quality was evaluated by SYRCLE and CAMARADES, respectively. Eligible studies included original articles published in English that evaluated cardiac outcomes in rodents submitted to over 4 weeks of RT and controlled by a sedentary, HFD-fed control group (n = 5). Results The results showed that RT mitigates cardiac oxidative stress, inflammation, and endoplasmic reticulum stress. It also modifies the activity of structural remodeling markers, although it does not alter biometric parameters, histomorphometric parameters, or the contractile function of cardiomyocytes. Conclusion Our results indicate that RT partially counteracts the HFD-induced adverse cardiac remodeling by increasing the activity of structural remodeling markers; elevating mitochondrial biogenesis; reducing oxidative stress, inflammatory markers, and endoplasmic reticulum stress; and improving hemodynamic, anthropometric, and metabolic parameters.

Do statins decrease testosterone in men? Systematic review and meta-analysis

ABSTRACT Purpose: Statins are one of the most prescribed classes of drugs worldwide to treat hypercholesterolemia and dyslipidemia. By lowering the level of cholesterol, the use of statin could cause a reduction in testosterone levels. The objective was to evaluate whether the continued use of statins in patients with hypercholesterolemia causes a deficiency in testosterone and other sex hormones. Materials and Methods: Systematic Review with Meta-analysis, performed in Embase, Medline and Cochrane databases, until May 2023; PROSPERO CRD42021270424protocol. Selection performed by two independent authors with subsequent conference in stages. Methodology based on PRISMA statement. There were selected comparative studies, prospective cohorts (CP), randomized clinical trials (RCT) and cross-sectional studies (CSS) with comparison of testosterone levels before and after statin administration and between groups. Bias analysis were evaluated with Cochrane Tool, The Newcastle-Ottawa Scale (NOS), and using the Assess the Quality of Cross-sectional studies (AXIS) tool. Results: There were found on MedLine, Embase and Cochrane, after selected comparative studies, 10CP and 6RCT and 6CSS for the meta-analysis. In the Forrest plot with 6CSS, a correlation between patients with continuous use of statins and a reduction in total testosterone was evidenced with a statistically significant reduction of 55.02ng/dL (95%CI=[39.40,70.64],I²=91%,p<0.00001). In the analysis with 5RCT, a reduction in the mean total testosterone in patients who started continuous statin use was evidenced, with a statistical significance of 13.12ng/dL (95%CI=[1.16,25.08],I²=0%,p=0.03). Furthermore, the analysis of all prospective studies with 15 articles showed a statistically significant reduction in the mean total testosterone of 9.11 ng/dL (95%CI=[0.16,18.06],I²=37%,p=0.04). A reduction in total testosterone has been shown in most studies and in its accumulated analysis after statin use. However, this decrease was not enough to reach levels below normal. Conclusion: Statins use causes a decrease in total testosterone, not enough to cause a drop below the normal range and also determines increase in FSH levels. No differences were found in LH, Estradiol, SHBG and Free Testosterone analysis.

Displasia dentinaria tipo I: Manejo clínico y estudio histológico a propósito de dos casos

La displasia dentinaria tipo I (DD-I) corresponde a una alteración dentinaria de heterogeneidad genética y penetrancia completa, en donde se presenta un defecto en el desarrollo de las raíces de los dientes tanto temporales como definitivos. Clínicamente se observan dientes con extrema movilidad junto con antecedentes de exfoliación prematura o espontánea. Los defectos estructurales de los tejidos dentarios, tales como DD-I; implican un desafío ya que son pocos los casos documentados en la literatura que hablan de esta condición. Además implican un tratamiento multidisciplinario y altamente invasivo. El objetivo de este artículo es presentar dos casos de DD-I, enfatizando en su tratamiento y características histopatológicas.

Dentin Dysplasia Type I (DD-I) consists of a pathological dentinary alteration with genetic heterogeneity that results in a defectuous development of dental roots both in primary and secondary dentition. Clinically we can appreciate teeth with extreme pathological mobility and premature or spontaneous exfoliation. Alterations within normal dental structure, such as DD-I imply a challenge for the common practitioner, because of the scarce number of case reports with in the scientific literature regarding this condition and also, because of the need for a highly invasive and multidisciplinary approach they require. The aim of this article is to present two DD-I cases, emphasizing on their treatment and histopathological features.

Parameters of pubertal growth spurt in children and adolescents living at high altitude in Peru

Abstract Objectives: The aim was to estimate the pubertal growth height of children and adolescents living in a high-altitude region of Peru using the Preece-Baines model 1 (1 PB). Methods: A cross-sectional study was conducted in schoolchildren from the department of Puno (Peru) between 3841 and 3874 masl. The age range was between 4 and 17 years. Standing height was evaluated. 1 PB was used to infer the mathematical and biological parameters of stature. Results: Mathematical parameters estimated by the 1 PB model reflected small residual standard error (RSE) values in both sexes (0.25 in boys and 0.27 in girls). In boys, the age at which peak velocity was reached (APHV) was estimated at 13.21 ± 0.33years. While in girls it was 9.96 ± 0.26years (p < 0.05). In general, girls reached APHV (y) 3.25 years earlier than boys. On the other hand, the growth velocity of maximum height [APHV (cm/y)] of boys was higher (6.33 ± 6.06 cm/y) relative to girls (6.06 ± 0.32 cm/y). Estimated final adult height (EFAH) in boys was reached at 166.020 ± 0.99 cm and height at maximum growth velocity (HPHV) was 153.07 ± 0.67 cm, while in girls they were significantly lower (EFAH; 153.74 ± 0.44 cm and HPHV: 139.73 ± 0.84 cm). Conclusions: This study showed that girls living in Puno at a high altitude in Peru reached APHV 3 years earlier than boys and at the same time reflected slower PHV. These results suggest that pubertal growth at high altitudes is slower in both sexes and especially in girls. Thus, modeling physical growth may be an important step in understanding the onset of puberty at different latitudes.

Nuevos tratamientos farmacológicos para la miocardiopatía hipertrófica: foco en inhibidores de miosina

La miocardiopatía hipertrófica (MCH), definida clínicamente como una hipertrofia ventricular izquierda no explicada por sobrecarga hemodinámica ni por infiltración, es la enfermedad miocárdica hereditaria más común. El tratamiento actual se basa en terapias de reducción septal en casos de Miocardiopatía hipertrófica obstructiva (MCHo), prevención de muerte súbita cardíaca mediante desfibrilador automático implantable y en el uso de fármacos para disminuir la obstrucción dinámica del tracto de salida del ventrículo izquierdo. Recientemente se han desarrollado diversos agentes que actúan sobre los mecanismos que, a nivel celular, llevan a la aparición de hipertrofia ventricular. Este artículo se centra en formas de tratamiento farmacológico desarrolladas en los últimos años, en especial con inhibidores de miosina. Se detallan los mecanismos de acción como también los resultados de diversos estudios clínicos de evaluaciones recientes.

Current clinical management of Hypertrophic Cardiomyopathy is mainly based on modifying physiologic mechanisms to decrease left ventricular outflow tract obstruction. Also important are agents that prevent and treat ventricular arrythmias. This review article is focused on the cellular mechanisms that underlie the development of ventricular hypertrophy and the effect of new myosin inhibitors such as mavcamten and aficamten. Promising results of recent clinical trials evaluating the effect of these agents are analyzed. The potential benefits of genetic therapy are also discussed.

Adaptación y validación de la Patient Health Questionnaire for Depression and Anxiety (PHQ-4) en una muestra de quechua hablantes peruanos

Introducción: El Patient Health Questionnaire for Depression and Anxiety (PHQ-4) es una medida de autoinforme ultrabreve de síntomas depresivos y ansiosos. El PHQ-4 no ha sido adaptado ni validado en la población quechua hablante. Objetivo: Este estudio tuvo como objetivo adaptar y validar el PHQ-4 en una muestra de población peruana quechua hablante en su variante Collao de Puno-Perú. Metodología: Participaron 221 personas hablantes de quechua variante collao (promedio de edad de 31,2 años, SD = 11,7, 47,1 % hombres y 52,9 % mujeres). Se evaluó la evidencia de validez basada en la estructura interna, mediante el análisis factorial confirmatorio (CFA), la fiabilidad con el método de consistencia interna y las características de dificultad y discriminación de los ítems en base a la Teoría de Respuesta al Ítem (IRT). Resultados: Los resultados indicaron que todos los ítems del PHQ-4 son relevantes, coherentes y claros para representar adecuadamente los síntomas de ansiedad y depresión. El resultado del AFC apoyó un modelo unifactorial, donde los ítems de ansiedad y depresión conforman una sola variable latente con una fiabilidad alta. Todos los ítems del PHQ-4 presentas buenos parámetros de discriminación y los parámetros de dificultad indican que los ítems son comparativamente difíciles. Por lo tanto, se necesita una mayor presencia del rasgo latente (ansiedad y depresión) para responder las categorías de respuesta más altas. Discusión: En conclusión, la PHQ-4 presentó buenas propiedades psicométricas como una medida de detección primaria rápida, confiable y válida para personas quechuahablantes que necesitan una evaluación profunda, monitoreo de los síntomas para diagnóstico y tratamiento para la ansiedad o depresión.

Introduction: The Patient Health Questionnaire for Depression and Anxiety (PHQ-4) is an ultra-brief self-report measure of depression and anxiety symptoms. The PHQ-4 has not been adapted or validated in the Quechua-speaking population. Objective: This study aimed to adapt and validate the PHQ-4 in a sample of the Peruvian Quechua-speaking population with its Collao variant from Puno-Peru. Methods: A total of 221 Quechua speakers of the Collao variant (mean age 31.2 years, SD = 11.7, 47.1% male and 52.9% female) participated. Evidence of validity based on internal structure was evaluated using confirmatory factor analysis (CFA), reliability using the internal consistency method, and item difficulty and discrimination characteristics based on Item Response Theory (IRT). Results: The results indicated that all items of the PHQ-4 were relevant, consistent, and clear enough to adequately represent anxiety and depressive symptoms. The CFA results supported a one-factorial model, in which anxiety and depression items form a single latent variable with high reliability. All items of the PHQ-4 had good discrimination parameters, and the difficulty parameters indicated that the items were comparatively difficult. Therefore, a higher presence of the latent trait (anxiety and depression) is needed to answer higher response categories. Discussion: In conclusion, the PHQ-4 presented good psychometric properties as a rapid, reliable, and valid primary screening measure for Quechua speakers in need of in-depth assessment and symptom monitoring for the diagnosis and treatment of anxiety and depression.

Caracterización de los desenlaces quirúrgicos a corto plazo en gastrectomía por laparoscopia en un centro de alto volumen: 10 años de experiencia / Short-term surgical outcomes of laparoscopic gastrectomy in a high-volume center: 10-year experience

Introducción. El cáncer gástrico en Colombia es la segunda neoplasia más común en hombres y la cuarta en mujeres. En los últimos años se han descrito ampliamente los beneficios del abordaje laparoscópico en el cáncer gástrico frente a sangrado, recuperación postoperatoria y complicaciones, sin afectar los resultados oncológicos. Métodos. Estudio observacional retrospectivo de pacientes llevados a gastrectomía laparoscópica en la Clínica Universitaria Colombia durante un período de diez años, entre 2013 y 2023. Se describieron los resultados perioperatorios en cuanto a estancia hospitalaria, sangrado operatorio, duración del procedimiento, complicaciones, causas de reintervención y mortalidad en los primeros 30 días. Resultados. Se incluyeron 418 pacientes, 58,9 % hombres, con una edad promedio de 60,8 años. Se documentó un tiempo quirúrgico promedio de 228,7 minutos, con un sangrado de 150 ml. La media de ganglios linfáticos resecados fue de 26,1 ± 11,4. La estancia hospitalaria en promedio fue de 4 ± 4 días, y se registraron complicaciones en 104 sujetos, con una tasa promedio de 24 %, de las cuales 29 (27,4 %) obtuvieron una clasificación Clavien-Dindo IIIB. Conclusiones. La gastrectomía por laparoscopia en un centro de alto volumen y con cirujanos experimentados en Colombia, tiene resultados perioperatorios similares a lo reportado en la literatura mundial. Aún se requiere de estudios de mayor fuerza de asociación para establecer recomendaciones sobre el uso rutinario de este abordaje en patología maligna avanzada.

Introduction. Gastric cancer in Colombia is the second most common neoplasm in men and the fourth in women. In recent years, the benefits of the laparoscopic approach in gastric cancer against bleeding, postoperative recovery com and complications have been widely described, without affecting oncological results. Methods. Retrospective observational study of patients undergoing laparoscopic gastrectomy at the Clínica Universitaria Colombia over a period of ten years, between 2013 and 2023. Perioperative results were described in terms of hospital stay, operative bleeding, duration of the procedure, complications, causes of reintervention, and mortality in the first 30 days. Results. 418 patients were included, 58.9% men, with an average age of 60.88 years. An average surgical time of 228.7 minutes was documented, with a blood loss of 150 ml. The mean number of lymph nodes resected was 26.1 ± 11.4. The average hospital stay was 4 ± 4 days, and complications were recorded in 104 subjects, with an average rate of 24%, of which 29 (27.4%) obtained a Clavien-Dindo IIIB classification. Conclusions. Laparoscopic gastrectomy in a high-volume center and with experienced surgeons in Colombia has perioperative results similar to those reported in the world literature. Studies with greater strength of association are still required to establish recommendations on the routine use of this approach in advanced malignant pathology.

A política nacional de práticas integrativas e complementares na grande Vitória: uma análise sobre os caminhos e proposições das PIC como proposta de tratamento de saúde do Sistema Único de Saúde (SUS) / The national policy for integrative and complementary practices in the metropolitan region of Vitória/ES: an analysis of the paths and propositions for PIC as a proposal for health treatment at the SUS / La política nacional de prácticas integrativas y complementarias en gran Vitória: un análisis sobre los caminos y proposiciones del PIC como propuesta de atención a la salud del Sistema Único de Salud (SUS)

Trata-se de uma pesquisa qualitativa que tem por objetivo investigar a implementação das Práticas Integrativas e Complementares no SUS na Grande Vitória. Como estratégia metodológica foram utilizadas as entrevistas semiestruturadas com três profissionais (servidoras públicas) que atuam neste contexto: uma professora de Educação Física, uma Psicóloga e uma Assistente Social. Os resultados indicam barreiras como o preconceito, a descrença e a falta de legitimidade das PIC, as quais dificultam tanto a atuação profissional, quanto a busca dos usuários por esses tratamentos (AU).

Qualitative research that investigated the implementation of Integrative and Complementary Practices in SUS. As a methodological strategy, semi-structured interviews were used with three professionals (public servants) who work in this context: a physical education teacher, a psychologist and a social worker. It was identified that most of the PIC are offered in the capital city, leaving the other municipalities short of services. About these services, the professionals claim that there are barriers such as prejudice, disbelief and lack of legitimacy of the PIC, which hinder both the professional performance and the users' search for these treatments (AU).
