Spatio-temporal composition of aquatic birds communityin Juluapan Lagoon, Colima, Mexican Central Pacific / Composición espacio-temporal de las aves acuáticas en la laguna Juluapan, Colima, en el Pacífico Central Mexicano

Abstract Introduction: Aquatic birds (AB) are usually associated with wetlands, which provide refuge, food, and/or nesting sites for resident and migratory species. Despite their ecological importance, there is little knowledge on AB in some tropical environments, such as those found on the Colima coast. Objective: To investigate the spatial and temporal composition of the AB community in Juluapan Lagoon, Colima, Central Mexican Pacific. Methods: Monthly counts were conducted between June 2017 and May 2018 during low-tide conditions to record habitat use by AB. Species richness and bird counts were obtained to compare sampling areas; mean richness and number of individuals were compared between seasons. Results: We detected 53 species and 5 750 individuals. The highest species richness and relative abundance values were obtained in winter at the lagoon area farthest from the connection with the marine system, where anthropogenic activity is lower. Diversity was greater in zones 2 and 3 in spring, summer, and fall. Muddy flats were the most used environment, and the most frequent activity was resting. Nesting activity was only recorded in the middle of the lagoon at the mangrove during spring. "Shorebirds" and "waders" were the most dominant groups in the bird community of the Juluapan lagoon. Conclusions: This coastal wetland is a site of great biological importance for aquatic birds; thus, conservation measures should be implemented, and there should be a continuous study of the effects of anthropogenic pressure.

Resumen Introducción: Las aves acuáticas (AA) son usualmente relacionadas a los humedales debido a que éstos funcionan como sitios de refugio, alimentación y anidación de diferentes especies residentes y migratorias. Sin embargo, el conocimiento sobre las aves acuáticas en algunos humedales es nulo. Objetivo: Investigar la composición espacio-temporal de la comunidad de AA en la laguna Juluapan, Colima, en el Pacífico Central Mexicano. Métodos: Entre junio de 2017 y mayo de 2018 se llevaron a cabo conteos mensuales en condiciones de marea baja para registrar el uso de hábitat de las AA. Se obtuvieron valores de riqueza de especies y número de individuos para realizar comparaciones entre zonas de muestreo, así como el promedio del número de especies y número de individuos para comparaciones entre temporadas. Resultados: Se registraron un total de 53 especies y 5 750 individuos. Los valores de riqueza de especies y densidad de individuos fueron más altos durante invierno, en la zona más alejada al ambiente marino, donde la actividad antropogénica es menor. La diversidad tuvo valores más altos en la zona 2 y 3, durante primavera, verano y otoño. El ambiente más explotado por las aves fueron las planicies lodosas; y el descanso fue la actividad más frecuente. Asimismo, la actividad de anidación sólo se registró en el manglar de la zona media durante primavera. Las "aves playeras" y "aves zancudas" fueron los grupos más predominantes en la comunidad de aves de la laguna Juluapan. Conclusiones: Este humedal costero es un sitio de gran importancia biológica para aves acuáticas, por lo que resulta necesario la implementación de medidas de conservación, así como el estudio de los efectos por la presión antropogénica.

Especialización o diversificación en el desarrollo deportivo: Una revisión integrativa / Specialization or Diversification in Sports Development: An Integrative Review / Especialização ou diversificação no desenvolvimento esportivo: uma revisão integrativa

Resumen Objetivo: Explorar y discutir literatura científica teórica y práctica para comparar la diversificación y la especialización deportivas tempranas como un enfoque deportivo y educativo. Métodos: Se realizó una revisión sistemática siguiendo las pautas PRISMA, se incluyó un total de 61 estudios. Resultados: Entrenadores, padres e hijos consideran que la mejor forma de desarrollar el talento deportivo y alcanzar la élite en el deporte es participar en una sola disciplina y hacerlo lo antes posible para lograr la especialización y las máximas habilidades técnicas, físicas y psicológicas. Los caminos de especialización deportiva pueden conducir a una situación física, social y mental que comprometa su desarrollo integral. Conclusión: Se puede plantear, en primer lugar, la diversificación deportiva en edades tempranas y luego la especialización; una vez alcanzadas las bases de la fuerza, el acondicionamiento y el entrenamiento neuromuscular, así como una maduración psicomotora específica, para que su rendimiento deportivo y su salud no se vean comprometidos en el mediano o largo plazo. Es necesario considerar que pocos niños logran obtener un lugar en los deportes de élite, por lo que, para muchos de ellos, la educación en torno al deporte será la base para el ejercicio de su ciudadanía como personas activas.

Abstract Purpose: To explore and discuss theoretical and practical scientific literature to compare sports diversification and early sports specialization as a sport and educational approach. Methods: A systematic review was conducted following PRISMA guidelines, and 61 studies were included. Results: Coaches, parents, and children consider that the best way to develop sports talent and enter the elite in sports is to practice a single discipline as early as possible to achieve specialization and maximum technical skills and physical and psychological conditions. Sports specialization paths may lead to a physical, social, and mental state that compromises their integral development. Conclusion: Sports diversification should be considered first at an early age and, afterward, the specialization once the bases of strength, conditioning, neuromuscular training, and a specific psychomotor maturation have been achieved, so that sports performance and health are not compromised in the medium or long term. It is necessary to consider that few children enter elite sports, so for many of them, sports education will be the basis for exercising their citizenship as active people.

Escarlatina estafilocócica como complicación de quemadura por contacto

El Staphylococcus aureus causa una variedad de infecciones localizadas e invasivas supurativas y 3 síndromes mediados por toxinas: Síndrome de choque tóxico estafilocócico (STSS, por sus siglas en ingles), síndrome de piel escaldada estafilocócica (SSSS) e intoxicación alimentaria1. La escarlatina estafilocócica está relacionada con las toxinas del STSS y SSSS. De hecho, se pudieron describir dos síndromes diferentes cada uno relacionado a un tipo de toxina que eran formas atenuadas de estas entidades. El curso de esta patología generalmente es autolimitado, pero puede evolucionar rápidamente a enfermedad severa que ponga en peligro la vida. Un entendimiento de este conjunto de patologías nos permite abordar al paciente de una manera oportuna, manteniendo la vigilancia y en caso de ser necesario intervenir para evitar el advenimiento del STSS que puede desembocar en falla orgánica múltiple e incluso la muerte. Esta revisión se trata de un caso atendido en la unidad de quemados del Hospital del Niño Dr. José Renán Esquivel (HDNJRE) en el mes de mayo del 2023 con quemadura por contacto complicada con escarlatina estafilocócica.

Staphylococcus aureus causes a variety of localized and invasive suppurative infections and 3 toxin-mediated syndromes: staphylococcal toxic shock syndrome (STSS), staphylococcal scalded skin syndrome (SSSS) and food poisoning1 . Staphylococcal scarlet fever is related to STSS and SSSS toxins. In fact, two different syndromes each related to a type of toxin could be described which were attenuated forms of these entities. The course of this pathology is usually self-limiting, but can rapidly progress to severe life-threatening disease. An understanding of this set of pathologies allows us to approach the patient in a timely manner, maintaining vigilance and if necessary intervening to prevent the advent of STSS that can lead to multiple organ failure and even death. This review is about a case treated at the burn unit of the Hospital del Niño Dr. José Renán Esquivel (HDNJRE) in May 2023 with contact burn complicated by staphylococcal scarlet fever.

Results: Among in individuals aged 20 to 29 years, which corresponds to 31.76% of total cases. It was also more common in males, corresponding to 78.45% of total cases. Car accidents were the most common cause, described in 22.31% of medical records, and the main fracture, present in 85.83% of cases, was of the bones of the nose. Conclusion: Victims of oral and maxillofacial trauma treated at the Hospital de Clínicas da Universidade Federal do Triângulo Mineiro are predominantly men in their third decade of life, involved in automobile accidents, with injuries to the bones of the nose that were treated electively.

Frequência e distribuição do gene da α-actinina-3 e sua associação em atletas brasileiras de voleibol / Frequency and distribution of the α -actinin-3 gene and its association in brazilian volleyball athletes

Introduction: The ACTN3 gene encodes the α-actinin-3 protein in the Z lines of the sarcomere, which anchors the actin protein in the contractile apparatus, present exclusively in type II muscle fibers, presenting greater glycolytic capacity, which is essential for sports with high-energy actions. intensity and short duration as is the case with Volleyball. Objective: To verify the frequency and distribution of the ACTN3 gene, RR and RX genotypes that express α-actinin-3 (EX α-actinin-3), and XX genotype that do not express α-actinin-3 (NE α-actinin-3) and its association with Brazilian volleyball athletes. Materials and Methods: Nine-seven (97) athletes from the women's volleyball super league took part in the study. Body mass, height and age were evaluated to characterize the sample. Salivary samples were analyzed using (PCR) in real time, to determine the genotypes, and, to verify the association of the genotype with the status of volleyball athlete in the three categories (National Teams, Brazilian National Team and Brazilian Olympic Team), the test was carried out Chi-square of independence (χ²). To obtain the odds ratio of the outcome, a log linear regression analysis was performed. All tests were carried out using the JAMOVI 2.4 (2023) statistical software. Results: Among the athletes in the sample competing in the National Teams competition, 91.8% have the EX-α-actinin-3 genotype. When we consider Brazilian National Team competitions, 93.7% have the EX-α-actinin-3 genotype. Athletes who play for the Brazilian Olimpic Team, 100% of the sample have the EX-α-actinin-3 genotype. Considering that in the world population, the frequency is 80%, it is possible to verify that as you approach the athletes who participate in the women's team there is a greater participation of athletes with the EX-α-actinin-3 genotype. Furthermore, there was an association between the genotypes that EX α-actinin-3 and the National category, with the status of elite athlete, where (χ²) obtained the p value (0.023) and the rate ratio (2.71) for the outcome of the genotypes (EX α-actinin-3) being elite athletes. Conclusion: The athlete's genetic characteristics, environment, nutrition, physical, technical and tactical preparation are some of the factors that contribute to sports performance. However, the results of the present study suggest that athletes with RR and RX genotypes that express α-actinin-3, present in type II muscle fibers, seem to confer an advantage when playing high-performance volleyball.

Conclusión: En pacientes con riesgo intermedio para coledocolitiasis, la ESBP es una opción diagnostica útil en el estudio de patologías pancreáticas, árbol biliar extrahepático, y la identificación de microlitiasis biliares; por lo que nos permite además poder complementarla con una intervención terapéutica como la CPRE en un solo tiempo.

ABSTRACT Objective: Determine the sensitivity and specificity of the ESBP for diagnosis in patients with intermediate risk of choledocholithiasis, referred to the specialized surgical Gastroenterology center of Unión de Cirujanos SAS - Oncologists of the West Zentria group - Manizales - Colombia between March 01, 2020 to January 31, 2022. Materials and methods: Retrospective cross-sectional study in patients with intermediate risk for choledocholithiasis. The diagnostic performance of ESBP was calculated and confirmed with ERCP. Negative ESBPs were followed up by telephone. Results: 752 cases with ESBP were analyzed, of which 43.2% (n=325) were positive and 56.8% (n=427) were negative. ERCP was performed in positive cases who accepted the procedure (n=317); 73.5% (n:233) were positive for choledocholithiasis, 25.8% (n=82) tumors and 0.6% (n=2) biliary roundworms. Patients with positive ESBP underwent ERCP. S= 98.3% (95% CI: 95.7-99.5) was obtained; E= 88.1% (95% CI: 79.2-94.1); PPV = 95.8% (95% CI: 92.4-98.0); NPV = 94.9% (95% CI: 87.4-98.7). The AUC of ESBP was 0.9319 (95% CI 0.8961-0.967). Conclusion: In patients with intermediate risk for choledocholithiasis, ESBP is a useful diagnostic option in the study of pancreatic pathologies, extrahepatic biliary tree, and the identification of biliary microlithiasis; Therefore, it also allows us to complement it with a therapeutic intervention such as ERCP in a single time.

Cohorte descriptiva de pacientes adultos con hipertensión portal en una institución de tercer nivel en Colombia / Descriptive cohort of adult patients with portal hypertension at a tertiary care institution in Colombia

Introducción. La hipertensión portal (HTP) se define como una elevación anormal de la presión venosa en el sistema portal que lleva al desarrollo de vías colaterales para desviar el flujo sanguíneo de la zona. Dentro de su etiología están las relacionadas con la cirrosis hepática y otras causas denominadas no cirróticas. El objetivo de este estudio fue evaluar los principales hallazgos demográficos, clínicos y paraclínicos en un grupo de pacientes con HTP, y determinar el uso de ayudas invasivas y no invasivas, y su disponibilidad para el diagnóstico y seguimiento de los pacientes en los centros que no cuentan con laboratorio de hemodinamia hepática, reflejando la dinámica de múltiples escenarios en Colombia. Metodología. Se realizó un estudio descriptivo de corte transversal, retrospectivo, en pacientes atendidos en una institución de tercer nivel del sur de Colombia, entre enero del año 2015 y diciembre del año 2020. Resultados. Se obtuvo una muestra de 61 pacientes en donde la mayoría de casos correspondían a hombres en la séptima década de la vida, procedentes del área urbana. La principal causa de consulta fue el sangrado digestivo (39,3 %), asociado a la presencia de telangiectasias (arañas vasculares) en el 37,2 %, seguido de circulación colateral (31,3 %) e ictericia (19,7 %). En la ecografía abdominal (realizada en el 57,4 % de los pacientes) predominaron la cirrosis (68 %) y la presencia de esplenomegalia (14,2 %), y en lospacientes con Doppler portal (realizado en el 16,4 %) se encontró hígado cirrótico (80 %) y dilatación portal (40 %). Con respecto a los hallazgos en la esofagogastroduodenoscopia predominó la presencia de várices esofágicas y gastritis crónica. Conclusión. El principal motivo de consulta fue el sangrado digestivo, en tanto que la cirrosis fue el antecedente y el hallazgo imagenológico más frecuente, seguido de las várices esofágicas. Se encontró que el uso de paraclínicos, ecografía abdominal, ecografía con Doppler portal y esofagogastroduodenoscopia fueron los más utilizados en el contexto clínico de los pacientes con el diagnóstico de HTP.

Introduction. Portal hypertension (PHT) is defined as an abnormal elevation of venous pressure in the portal system that leads to the development of collateral pathways to divert blood flow from the area. Within its etiology are those related to liver cirrhosis and other so-called non cirrhotic causes. The aim of this study was to evaluate the main demographic, clinical and paraclinical findings in a group of patients with PHT, and to determine the use of invasive and non-invasive aids, and their availability for the diagnosis and follow-up of patients in centers that do not have a hepatic hemodynamics laboratory, reflecting the dynamics of multiple scenarios in Colombia. Methodology. A descriptive, retrospective, cross-sectional, retrospective study was conducted in patients attended in a third level institution in Southern Colombia, between January 2015 and December 2020. Results. A sample of 61 patients was obtained where the majority of cases corresponded to men in the seventh decade of life, from the urban area. The main cause of consultation was digestive bleeding (39.3%), associated with the presence of telangiectasias (spider veins) in 37.2%, followed by collateral circulation (31.3%) and jaundice (19.7%). In abdominal ultrasound (performed in 57.4% of the patients), cirrhosis (68%) and the presence of splenomegaly (14.2%) predominated, and in patients with portal Doppler (performed in 16.4%), cirrhotic liver (80%) and portal dilatation (40%) were found. With respect to the findings in the esophagogastroduodenoscopy, esophageal varices and chronic gastritis were predominant. Conclusion. The main reason for consultation was gastrointestinal bleeding, while cirrhosis was the most frequent history and imaging finding, followed by esophageal varices. It was found that the use of paraclinics, abdominal ultrasound, ultrasound with portal Doppler and esophagogastroduodenoscopy were the most used in the clinical context of patients diagnosed with PHT.

Insertion torque, flexural strength and surface alterations of stainless steel and titanium alloy orthodontic mini-implants: an in vitro study

ABSTRACT Objective: This study aimed to compare the insertion torque (IT), flexural strength (FS) and surface alterations between stainless steel (SS-MIs) and titanium alloy (Ti-MIs) orthodontic mini-implants. Methods: Twenty-four MIs (2 x 10 mm; SS-MIs, n = 12; Ti-MIs, n = 12) were inserted on artificial bone blocks of 20 lb/ft3 (20 PCF) and 40 lb/ft3 (40 PCF) density. The maximum IT was recorded using a digital torque meter. FS was evaluated at 2, 3 and 4 mm-deflection. Surface topography and chemical composition of MIs were assessed by scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDS). General linear and mixed models were used to assess the effect of the MI type, bone density and deflection on the evaluated outcomes. Results: The IT of Ti-MIs was 1.1 Ncm greater than that obtained for the SS-MIs (p= 0.018). The IT for MIs inserted in 40 PCF test blocks was 5.4 Ncm greater than that for those inserted in 20 PCF test blocks (p < 0.001). SS-MIs inserted in higher density bone (40 PCF) had significantly higher flexural strength than the other groups, at 2 mm (98.7 ± 5.1 Ncm), 3 mm (112.0 ± 3.9 Ncm) and 4 mm (120.0 ± 3.4 Ncm) of deflection (p< 0.001). SEM evidenced fractures in the Ti-MIs. EDS revealed incorporation of 18% of C and 2.06% of O in the loaded SS-MIs, and 3.91% of C in the loaded Ti-MIs. Conclusions: Based on the findings of this in vitro study, it seems that SS-MIs offer sufficient stability and exhibit greater mechanical strength, compared to Ti-MIs when inserted into higher density bone.

RESUMO Objetivo: O objetivo deste estudo foi comparar o torque de inserção (TI), a resistência flexural (RF) e as alterações de superfície em mini-implantes ortodônticos de aço inoxidável (MIs-Ai) e de liga de titânio (MIs-Ti). Métodos: Vinte e quatro MIs (2 x 10 mm; MIs-Ai, n = 12; MIs-Ti, n = 12) foram inseridos em blocos de osso artificial de densidades de 20 lb/ft3 (20 PCF) e 40 lb/ft3 (40 PCF). O torque máximo de inserção foi registrado por meio de um torquímetro digital. A resistência flexural foi avaliada nas deflexões de 2, 3 e 4 mm. Topografia de superfície e composição química dos MIs foram avaliadas por Microscopia Eletrônica de Varredura (MEV) e Espectroscopia de Energia Dispersiva de Raios X (EDS). Modelos lineares gerais e mistos foram utilizados para avaliar o efeito do tipo de MI, da densidade óssea e da deflexão nos desfechos avaliados. Resultados: O TI dos MIs-Ti foi 1,1 Ncm maior do que o obtido para os MIs-Ai (P = 0,018). O TI para MIs inseridos em blocos de teste de 40 PCF foi 5,4 Ncm maior do que para aqueles inseridos em blocos de teste 20 PCF (p < 0,001). MIs-Ai inseridos em osso de maior densidade (40 PCF) apresentaram resistência flexural significativamente maior do que outros grupos, em deflexões de 2 mm (98,7 ± 5,1 Ncm), 3 mm (112,0 ± 3,9 Ncm) e 4 mm (120,0 ± 3,4 Ncm) (p < 0,001). A MEV evidenciou fraturas nos MIs-Ti. A EDS revelou incorporação de 18% de C e 2,06% de O nos MIs-Ai e 3,91% de C nos MIs-Ti, ambos submetidos a testes mecânicos. Conclusões: Com base nos resultados desse estudo in vitro, os MIs-Ai aparentam oferecer adequada estabilidade e maior resistência mecânica, em comparação aos MIs-Ti, quando inseridos em osso de maior densidade.

Objetivo: determinar las complicaciones intrahospitalarias y los desenlaces de los estados hiperglucémicos en pacientes adultos internados en el Hospital Nacional, Itauguá, Paraguay, en el periodo 2015-2022. Metodología: se aplicó un diseño de cohortes retrospectivas. Se seleccionaron pacientes con diagnósticos de diabetes mellitus tipo 1 y tipo 2, mayores de 18 años, de ambos sexos, agrupados en tres cohortes que corresponden a cada una de las descompensaciones agudas de la diabetes mellitus. La muestra estuvo conformada por 180 pacientes distribuidos en tres grupos de cohortes con 60 pacientes cada una. Resultados: 51% correspondió al sexo masculino. Se halló mayor desarrollo de eventos cardiovasculares, infecciones intrahospitalarias, requerimiento de cuidados intensivos y mortalidad en la cohorte con estado hiperosmolar. Conclusión: la cohorte con estado hiperosmolar hiperglucémico se caracterizó por la mayor cantidad de complicaciones.

Introduction: The most serious complications of diabetes mellitus are diabetic ketoacidosis and the hyperosmolar hyperglycemic state. Clinical and laboratory alterations are often observed that cover both spectrums and which we call a mixed state. They represent close to 50% of hospitalizations in the service. of emergencies in diabetic patients. Objective: To determine in-hospital complications and outcomes of hyperglycemic states in adult patients admitted to the Hospital Nacional, Itauguá, Paraguay, in the period 2015-2022. Methodology: A retrospective cohort design was applied. Male and female patients with diagnoses of type 1 and type 2 diabetes mellitus, who were over 18 years of age, were selected and grouped into three cohorts that corresponded to each of the acute decompensations of diabetes mellitus. The sample was made up of 180 patients distributed into three cohort groups with 60 patients each. Results: Fifty one percent were male. A greater development of cardiovascular events, hospital-acquired infections, intensive care requirements and mortality were found in the cohort with hyperosmolar state. Conclusion: the cohort with hyperglycemic hyperosmolar state was characterized by the highest number of complications.

The intra- and inter-rater reproducibility of bone level measurements at strategic mini-implants using dental panoramic radiography

Abstract Objectives: This experimental study focused on the intra- and inter-rater reproducibility of vertical bone level (VBL) measurements at strategic mini-implants (MI) using digital panoramic radiographs (PR). Study design: VBLs of 152 MIs for removable partial denture stabilization at 50 randomly chosen PRs from a clinical trial were digitally evaluated by three ratters. Rater deviations exceeding 0.5 mm were re-examined. The intra-class correlation coefficient (ICC) was applied to estimate reliability. The smallest detectable change (SDC) was interrelated to the minimal clinically important change of 0.2 mm. Results: The first measurement round revealed intra- and inter-rater ICCs of > 0.8. However, 28 sites (9 %) were unreadable, and 97 sites (32 %) revealed differences between observers of ≥ 0.5 mm. Following a consensus session and re-training, an additional 8 sites were excluded and all remaining VBL differences were ≤ 0.5 mm. Thus, the SDCs with 95 % credibility were improved from 0.73 to 0.31 mm in the intra-rater and from 1.52 to 0.34 mm in the interrater statistics. Given a 50 % credibility for this special setting, both the intra- and inter-rater SDCs were 0.11 mm. Conclusions: Digital PR can be reliably utilized to determine VBLs around MIs under conditions of at least two trained observers, mutual calibration sessions, and exclusion of unquantifiable radiographs.
