RESUMO
BACKGROUND: Developmental Dysplasia of the Hip (DDH) is a condition affecting hip joint development in children, presenting multiple manifestations. Immobilization methods to ensure hip concentricity, such as the human position and modified Lange position, vary in effectiveness and risks, especially avascular necrosis. The purpose of this study was to identify whether closed reduction (CR), with two different immobilization techniques, is effective in avoiding complications such as residual hip dysplasia (RHD), re-dislocation, and Avascular Necrosis (AVN). METHODS: A total of 66 patients with DDH (84 hips) were treated with two different techniques of immobilization (groups A and B); the mean age at the time of reduction was 8 (6-13) months. The rates of RHD, Re-dislocation, and AVN were determined with a minimum follow-up of 48 months in both techniques. RESULTS: The Chi-square analysis conducted across the study groups unveiled that patients in Group B demonstrated a protective effect against AVN compared to those in Group A (OR: 0.248, 95% CI: 0.072-0.847, p = 0.026). However, no statistically significant differences were found between the groups concerning RHD (p = 0.563) and re-dislocation (p = 0.909). CONCLUSIONS: After the initial Human Position immobilization, the second cast with the modified Lange "second position" demonstrated a protective effect compared with maintaining the Human Position immobilization throughout the immobilization period, reducing the likelihood of AVN development in patients undergoing closed reduction for developmental dysplasia of the hip.

La Economía Circular (EC) se ha posicionado como una alternativa viable ante la insostenibilidad del modelo económico lineal. Hoy este constituye una temática que está en el centro del debate y de todas las agendas de gobierno y Cuba no puede ser la excepción. El presente artículo persigue como objetivo principal diagnosticar el estado de la economía circular en Cuba desde la perspectiva de las empresas estatales. En este sentido se parte de sistematizar las ventajas de la aplicación de modelos circulares en el país. Se particulariza en el estudio por sectores que han avanzado en la aplicación del paradigma circular y se concluye con una propuesta de acciones estratégicas a seguir para expandir las prácticas circulares en el país, las cuales son validadas según criterio de los principales usuarios responsables de su implementación a través de la técnica de IADOV
The Circular Economy (CE) has positioned itself as aviable alternative to the unsustainability of the linear economic model. Today this is an issue that is at the center of the debate and of all government agendas, and Cuba cannot be the exception. The main objective of this article is to diagnose the state of the circular economy in Cuba from the perspective of public enterprises. îe study is particularized to analyze separately the advance of the different sectors in the application of the circular paradigm. It concludes with a proposal of strategic actions to be followed to expand circular practices in the country, which are validated according to the criteria of the main users responsible for their implementation through the IADOV technique
RESUMO
Resumen Introducción: el tamizaje auditivo es un método de detección y su propósito es intervenir de forma temprana para reducir las consecuencias negativas de una eventual afección auditiva en el desarrollo integral del infante. Costa Rica ha implementado en el sistema de salud público un programa de tamizaje auditivo neonatal universal, donde se examina todo niño o niña antes del primer mes de vida. Aunque se han percibido múltiples beneficios, es importante demostrar con evidencia científica si cumple sus objetivos. Metodología: se analizó la eficacia del «Programa de tamizaje auditivo neonatal universal» (TANU) de la Caja Costarricense de Seguro Social, a partir de la información registrada de 37 656 infantes evaluados entre los años 2016 y 2018, mediante el contraste empírico con las técnicas descriptivas de distribución de frecuencias de variables, y las pruebas inferenciales chi cuadrado y análisis de varianza (ANOVA). Resultados: en cuanto a la edad al momento del examen, el 71 % de la muestra tenía entre 0 y 3 días. Su desempeño a través del tiempo y la extensión a distintos centros de salud ha sido satisfactorio, así mismo, la cantidad de infantes valorados ha sido hasta del 98 % de la población. Conclusiones: el programa TANU es eficaz en la mayoría de aspectos analizados, destaca la identificación de factores de riesgo y la detección temprana de afecciones auditivas, sin embargo, se proponen mejoras en relación con el manejo de la información.
Abstract Introduction: Hearing screening is a detection method, its objective is to provide an early intervention that allows reducing the negative consequences of an eventual hearing impairment, in the integral development of the infant. Costa Rica has implemented a universal neonatal hearing screening program in the public health system, where the hearing of every child born in the country is examined before the first month of life. Although multiple benefits have been perceived, it is important to demonstrate with scientific evidence if it accomplishes its objectives. Methodology: the effectiveness of the Universal Newborn Hearing Screening Program in Costa Rica was analyzed, based on the information recorded from 37,656 children evaluated since 2016 to 2018, through empirical contrast using both descriptive techniques: frequency distribution of variables, as well as the use of inferential tests: chi square and analysis of variance (ANOVA). Results: 71 % of the sample was between 0 and 3 days old at the moment of being examined. Its performance over time and extension to different health centers has been satisfactory, likewise, the number of infants evaluated has been up to 98 % of the population. Conclusions: the TANU program is effective in most of the aspects analyzed, the identification of risk factors and the early detection of hearing disorders are outstanding, however, improvements are proposed in relation to the handling of information.

La displasia ectodérmica hipohidrótica es un síndrome genético, caracterizado principalmente por hipohidrosis, hipotricosis e hipodoncia. Esta enfermedad es asociada con hipodoncia y atrofia de los procesos alveolares. El aspecto facial y la ausencia dental múltiple puede ser causa de problemas de socialización por parte de los niños afectados. El propósito de este reporte es describir las características y el manejo odontológico y protésico de un paciente masculino de 5 años de edad diagnosticado con el síndrome.
Hypodriotic ectotermal dysplasia is a genetic syndrome characterized mainly by hypodriosis, hypotrichosis and hypodontia. This disesase is associated with hypodontia and atrophy of the alveolar process. The facial aspect and the multiple missing teeth can cause problems of socialization of the affected children. The aim of this report is to describe features and dental and prosthetic management of a 5-year-old boy, diagnosed with the syndrome.

Milk fat/protein degrading microorganisms were isolated from different locations of a dairy wastewater treatment system with the goal of developing an inoculum for bioaugmentation strategies. Eight isolates, identified by 16S rRNA gene sequence analysis as belonging to the genera Bacillus, Pseudomonas, and Acinetobacter, were tested for their ability to remove COD and protein from a milk-based medium (3000 mg/L COD) and compared to a commercial bioaugmentation inoculum. The Acinetobacter isolate exhibited a pellet-type growth in liquid culture, a property that could potentially aid in the separation of microbes and liquid phase following treatment. Based on the individual degradation capacity and growth behavior of the isolates, three microorganisms were further selected and tested together. This consortium exhibited a COD removal similar to the commercial inoculum (57% and 63%, respectively), but higher protein (consortium: 93%; commercial inoculum: 54%), and fat removals (consortium: 75%; commercial inoculum: 38%).
