RESUMO

Background: Various coping strategies have been shown to alleviate the negative effects of trauma, yet the significance of prosocial behaviour in this realm has been notably underexplored. The present study explored the hypothesis that engaging in prosocial behaviour mitigates the impacts of trauma by promoting a sense of competence and relatedness, post-traumatic growth (PTG), and reconstruction of meaning.Methods: Three consecutive studies were conducted with college students to compare differences in consequence of prosocial behaviours between a trauma group and a control group. Study 1 (N = 96) used self-reported experiences of traumatic vs non-traumatic events; Study 2 (N = 43) used exposure vs. no exposure to video of an earthquake; Study 3 (N = 20) used a randomized controlled trial (RCT) of a prosocial-themed intervention vs. no intervention. Outcomes in all studies were assessed by self-report questionnaires.Results: Trauma damaged participants' sense of competence and meaningfulness. Prosocial behaviour relieved the impact of trauma on meaning, specifically manifested in the individuals' sense of meaningfulness and their search for meaning. Group interventions with a prosocial theme (based on effect size results) reduced post-traumatic stress disorder (PTSD) and enhanced PTG in victims. The promoting effect on PTG persisted a month later, and its enhancing effect on meaning manifested with a delay.Conclusion: Prosocial behaviour can potentially serve as a beneficial strategy for individuals coping with trauma because it helps enhance meaning and promotes PTG in victims. This conclusion is supported by laboratory experiments and a tentative small-scale intervention study, which provide an innovative perspective for future trauma interventions.

RESUMO

INTRODUCTION: Our aim was to determine which foetal or neonatal growth curves discriminate the probability of dying of newborns with low birth weight for their gestational age (small for gestational age, SGA) and sex (weight < 10th percentile) and to establish the curves that are presumably most useful for monitoring growth through age 10 years. MATERIAL AND METHODS: The analysis included every neonate (15 122) managed in our hospital (2013-2022) and all neonates born preterm before 32 weeks (6913) registered in the SEN1500 database (2019-2022). We considered most useful those curves with the highest likelihood ratio (LR) for dying with or without a history of SGA in each subgroup of gestational ages. Theoretically, the optimal curves for monitoring growth would be those with a higher R2 in the quantile regression formulas for the 50th percentile. RESULTS: The growth curves exhibiting the strongest association between SGA and hospital mortality are the Intergrowth fetal curves and the Fenton neonatal curves in infants born preterm before 32 weeks. However, the optimal curves for premature babies and neonates overall were those of Olsen and Intergrowth. The most useful curves to monitor anthropometric values alone until age 10 years of age are the longitudinal Intergrowth curves followed by the WHO standards, but if a single reference is desired from birth through age 10 years, the best option is the Fenton curves followed by the WHO standards. CONCLUSIONS: The Intergrowth reference provides the most discriminating foetal growth curves. In neonatal clinical practice, the optimal references are the Fenton followed by the WHO charts.

RESUMO

Objectives: Evaluate indicators and identify associated factors of post-traumatic stress disorder (PTSD) and post-traumatic growth (PTG) in individuals undergoing oncological treatment. Method: Quantitative, cross-sectional, analytical survey design with a non-probabilistic sample of 74 participants. Six instruments measuring PTSD, PTG, spiritual well-being, illness perception, and social support were employed. Data were analyzed using descriptive and inferential statistics in the Statistical Package for Social Science (SPSS). Results: It was evidenced that 21.60% of patients presented clinical indices of PTSD, and 85.12% showed a high index for PTG. High satisfaction indices were also observed for social support (86.48%), spiritual well-being (95.94%), and in identifying cancer as a potential threat to life (71.57%). Females, unmarried individuals, those inactive or unemployed, and those receiving public health support exhibited higher PTG indices. Women exhibit higher PTSD indices than men. Negative correlations were found between PTSD and spiritual well-being, and positive correlations with illness perception. Illness perception emerged as the variable with the greatest predictive power for PTSD indices. Conclusions: It is concluded that the threatening perception of the illness is a predictor of PTSD, highlighting it as a risk factor that requires attention in health prevention plans.(AU)


Objetivos: Evaluar los indicadores e identificar los factores asociados al trastorno de estrés postraumático (TEPT) y al crecimiento postraumático (CPT) en personas sometidas a tratamiento oncológico. Método: Diseño cuantitativo, transversal, analítico y de encuesta, con una muestra no probabilística compuesta por 74 participantes, utilizando seis instrumentos que miden TEPT, CPT, bienestar espiritual, percepción de la enfermedad y apoyo social, analizados a través de estadísticas descriptivas e inferenciales, en el Programa Estadístico para Ciencias Sociales (SPSS). Resultado: Se evidenció que 21,60% de los pacientes presentaron índices clínicos de TEPT y 85,12% un índice elevado para CPT. También se observaron índices elevados de satisfacción con el apoyo social (86,48%), bienestar espiritual (95,94%) e identificación del cáncer como una posible amenaza a la vida (71,57%). Las personas del género femenino, solteras, inactivas o desempleadas y atendidas por el servicio público de salud presentan mayores índices de CPT. Las mujeres muestran mayores índices de TEPT que los hombres. Se encontraron correlaciones negativas entre TEPT y bienestar espiritual y correlaciones positivas con la percepción de la enfermedad. La percepción de la enfermedad fue la variable con mayor poder predictivo para los índices de TEPT. Conclusiones: Se concluye que la percepción amenazante de la enfermedad es un predictor de TEPT, siendo esta una variable de riesgo que requiere atención en los planes de prevención de daños a la salud.(AU)

RESUMO

Introducción: el déficit de crecimiento mandibular es un aspecto muy importante en los pacientes en crecimiento, ya que genera diferentes tipos de patología a nivel facial, bucal y funcional. Objetivo: el propósito de este trabajo es dar a conocer resultados de la investigación realizada sobre los cambios faciales, alveolares y dentales que se producen en tratamientos sobre pacientes en crecimiento con Twin Block Modificado (TBM), combinado con aparatología fija multibrackets para el acabado dentario final. Material y método: la población estudiada son 24 pacientes, 16 de sexo femenino (66,6%), y 8 de sexo masculino (33,33%), con edades comprendidas entre los 12 y 15 años, que presentaron un valor del ángulo ANB de clase II (ángulo formado por el punto A - punto Na - punto B). Se utilizaron las telerradiografías laterales de cráneo iniciales y finales del mencionado grupo, habiéndose creado un método específico de 26 medidas para realizar la investigación. Resultados: en los resultados obtenidos de la muestra se ha observado un claro aumento de los valores del crecimiento mandibular, tanto verticales como horizontales, como los valores que evalúan la posición sagital horizontal de los dientes inferiores del grupo estudiado. Conclusiones: los resultados muestran una relevante diferencia a favor de tratar con TBM a los pacientes que se encuentren en crecimiento con la mandíbula en una posición posterior respecto al maxilar. (AU)


Introduction: Mandibular growth deficiency is a very important condition in patients who are still growing, as it can lead to different types of pathology at the facial, mouth and functional level. Objective: The purpose of this work is to publicize the results of the research that the doctoral candidate is carrying out on the facial, alveolar and dental changes that occurin treatments on growing patients with Modified Twin Block (from this moment abbreviated as TBM). Material and method: The population studied is 24 patients, 16 female (66.6%), and 8 male (33.33%), aged between 12 and 15 years, who presented a value of the class II ANB angle (angle formed by point A - point Na - point B). The initial and final lateral skull radiographs of the aforementioned group were used, having created a specific method of 27 measurements to carry out the research. Results: In the results obtained from the sample, a clear increase in the values of mandibular growth, both vertical and horizontal, has been observed, as well as the values that evaluate the horizontal sagittal position of the lower teeth of the group studied. Conclusions: The results show a relevant difference in favor of treating with TBM patients who are growing with the mandible in a posterior position with respect to the maxilla. (AU)

RESUMO

Background: During peacekeeping missions, military personnel may be involved in or exposed to potentially morally injurious experiences (PMIEs), such as an inability to intervene due to a limited mandate. While exposure to such morally transgressive events has been shown to lead to moral injury in combat veterans, research on moral injury in peacekeepers is limited.Objective: We aimed to determine patterns of exposure to PMIEs and associated outcome- and exposure-related factors among Dutch peacekeepers stationed in the former Yugoslavia during the Srebrenica genocide.Method: Self-report data were collected among Dutchbat III veterans (N = 431). We used Latent Class Analysis to identify subgroups of PMIE exposure as assessed by the Moral Injury Scale-Military version. We investigated whether deployment location, posttraumatic stress disorder (PTSD), posttraumatic growth, resilience, and quality of life differentiated between latent classes.Results: The analysis identified a three-class solution: a high exposure class (n = 79), a moderate exposure class (n = 261), and a betrayal and powerlessness-only class (n = 135). More PMIE exposure was associated with deployment location and higher odds of having probable PTSD. PMIE exposure was not associated with posttraumatic growth. Resilience and quality of life were excluded from analyses due to high correlations with PTSD.Conclusions: Peacekeepers may experience varying levels of PMIE exposure, with more exposure being associated with worse outcomes 25 years later. Although no causal relationship may be assumed, the results emphasize the importance of better understanding PMIEs within peacekeeping.


Peacekeeping veterans reported different patterns of exposure to potentially morally injurious experiences: high exposure, moderate exposure, or experiences of betrayal and powerlessness only.Deployment location predicted the pattern of exposure.More exposure was associated with worse psychological outcomes 25 years later.

RESUMO

Introducción. El tamaño al nacer se encuentra sujeto a influencias genéticas y ambientales; la altura geográfica es muy influyente. El peso al nacer (PN) es el indicador más utilizado para evaluarlo; existen diferentes estándares y referencias. Debido a la variabilidad de la distribución del PN en relación con la altura en la provincia de Jujuy (Argentina), este trabajo analiza la distribución percentilar del PN para tierras altas (TA) y tierras bajas (TB) jujeñas según edad gestacional (EG) y sexo, y su comparación con una referencia nacional y el estándar internacional INTERGROWTH-21st (IG-21). Población y métodos. Se analizaron los registros de 78 524 nacidos vivos en Jujuy en el período 20092014. Utilizando el método LMS, se estimaron los percentiles 3, 10, 50, 90 y 97 de PN/EG por sexo, para TA (≥2000 msnm), TB (<2000 msnm) y el total provincial, y se compararon gráficamente con la referencia poblacional argentina de Urquía y el estándar IG-21. La significación estadística se determinó mediante la prueba de Wilcoxon. Resultados. El PN en Jujuy presentó distribución heterogénea, con diferencias estadísticamente significativas (p <0,05) entre TB y TA. Al comparar con la referencia nacional y el estándar IG-21, se observaron diferencias por altitud, principalmente en los percentiles 90 y 97 para ambas regiones, y en los percentiles 3 y 10 en TA comparados con el estándar. Conclusiones. Se observó variabilidad de la distribución del PN asociada a la altura geográfica, por lo que, para evaluar el crecimiento intrauterino, resulta fundamental incluir la EG y el contexto donde transcurre la gestación.


Introduction. Size at birth is subject to genetic and environmental influences; altitude is highly influential. Birth weight (BW) is the most widely used indicator to assess size at birth; different standards and references are available. Due to the variability in BW distribution in relation to altitude in the province of Jujuy (Argentina), the purpose of this study is to analyze the percentile distribution of BW in the highlands (HL) and the lowlands (LL) of Jujuy based on gestational age (GA) and sex and compare it with a national reference and the INTERGROWTH-21 st (IG-21) international standard. Population and methods. The records of 78 524 live births in Jujuy in the 2009­2014 period were analyzed. Using the LMS method, the 3 rd, 10 th, 50 th, 90 th, and 97 th percentiles of BW/GA by sex were estimated for the HL (≥ 2000 MASL), the LL (< 2000 MASL), and the total for Jujuy, and compared with the Argentine population reference by Urquía and the IG-21 standard using growth charts. The statistical significance was established using the Wilcoxon test. Results. BW in Jujuy showed a heterogeneous distribution, with statistically significant differences (p < 0.05) between the LL and the HL. When compared with the national reference and the IG-21 standard, differences in terms of altitude were observed, mainly in the 90 th and 97 th percentiles for both regions and the 3 rd and 10 th percentiles in the HL compared with the international standard. Conclusions. BW distribution varied in association with altitude; therefore, to assess intrauterine growth, it is critical to include GA and the environment in which the pregnancy takes place.

RESUMO

ANTECEDENTES: Las gestaciones múltiples sugieren un mayor riesgo de mortalidad perinatal. Dentro de estas estadísticas, la muerte de un solo gemelo ocurre en hasta el 6% de los embarazos múltiples. La incidencia general después de las 20 semanas de gestación (sdg) se estima entre el 2.6% y el 6.2% de todos estos embarazos. Se ha demostrado que es la coriónicidad, más que la cigosidad, la que influye en el resultado de esta complicación, debido a la angioarquitectura placentaria de las circulaciones en los embarazos monocoriónicos. Las tasas de pérdida de hasta el 30-50% se han asociado con embarazos monocoriónicos y monoamnióticos. Si ocurre antes de las 14 sdg, el embrión puede desaparecer; entre las 14 y las 20 sdg, el feto se reduce en tamaño y volumen. Y, si ocurre después de 20 sdg, el feto permanece dentro del útero hasta el final de la gestación. CASO CLÍNICO: femenina de 18 años de edad, quien acudió a revisión obstétrica con reporte ultrasonográfico de un embarazo gemelar monocorial biamniótico de 30.4 sdg, y muerte de uno de los gemelos. Tras demostrar estabilidad hemodinámica del feto sobreviviente, así como estabilidad materna, se decidió internamiento para monitoreo estrecho. Una semana después desarrolló trabajo de parto pretérmino y se decidió la interrupción de la gestación de manera urgente. Se obtuvo un recién nacido masculino con edad gestacional sugestiva de 32 sdg, con dificultad respiratoria y requirió hospitalización para monitoreo estrecho del recién nacido prematuro. Madre egresó a las 48 horas, nunca desarrolló datos de coagulación intravascular diseminada (CID) y el recién nacido se mantuvo en hospitalización aproximadamente 3 semanas y media hasta que se egresó por adecuada adaptación. Nunca se demostró afectación neurológica o de algún otro órgano o sistema. CONCLUSIONES: Los factores más importantes al considerar el riesgo para el gemelo sobreviviente son la edad gestacional a la que ocurre la muerte del otro feto, y la corionicidad. El manejo debe incluir ecografías seriadas y programadas para el crecimiento. Estudios de Doppler arterial/venoso periférico e intracardiaco y una resonancia magnética al menos 3 semanas después de la muerte fetal para buscar cambios en el cerebro del gemelo sobreviviente. A pesar de que existen casos reportados de manejo conservador, es necesario el seguimiento estricto de datos de CID maternos, así como de desprendimiento prematuro de placenta normoinserta.

BACKGROUND: Multiple gestations suggest an increased risk of perinatal mortality. Within these statistics, death of a single twin occurs in up to 6% of multiple pregnancies. The overall incidence after 20 weeks gestation (sdg) is estimated to be between 2.6% and 6.2% of all such pregnancies. Chorionicity, rather than zygosity, has been shown to influence the outcome of this complication, due to the placental angioarchitecture of the circulations in monochorionic pregnancies. Loss rates of up to 30-50% have been associated with monochorionic and monoamniotic pregnancies. If it occurs before 14 sdg, the embryo may disappear; between 14 and 20 sdg, the fetus is reduced in size and volume. And, if it occurs after 20 sdg, the fetus remains inside the uterus until the end of gestation. CLINICAL CASE: 18-year-old female, who attended an obstetric check-up with an ultrasonographic report of a biamniotic monochorionic twin pregnancy of 30.4 sdg, and death of one of the twins. After demonstrating hemodynamic stability of the surviving fetus, as well as maternal stability, it was decided to hospitalize her for close monitoring. One week later she developed preterm labor and it was decided to terminate the pregnancy urgently. A male newborn was obtained with a gestational age suggestive of 32 sdg, with respiratory distress and required hospitalization for close monitoring of the premature newborn. Mother was discharged at 48 hours, never developed disseminated intravascular coagulation (DIC) and the newborn remained in hospital for approximately 3 and a half weeks until he was discharged due to adequate adaptation. No neurologic or other organ or system involvement was ever demonstrated. CONCLUSIONS: The most important factors when considering the risk to the surviving twin are the gestational age at which the death of the other fetus occurs, and chorionicity. Management should include serial and scheduled ultrasounds for growth. Peripheral arterial/venous and intracardiac Doppler studies and MRI at least 3 weeks after fetal death to look for changes in the brain of the surviving twin. Although there are case reports of conservative management, close monitoring of maternal DIC data, as well as normoinsert placental abruption, is necessary.     (provided by Infomedic International)

RESUMO

OBJECTIVE: The aim of the study is to show for the first time how aflibercept affects endometriosis lesions. MATERIAL AND METHODS: Surgically induced endometriosis in Wistar albino female rats. Rats with endometriosis were randomly divided into three groups: control (Co), aflibercept (Af), and leuprolide acetate (Le). Then, Af, aflibercept, and Le received leuprolide acetate. The control group was not treated. The weights and changes in intra-abdominal adhesions of the rats before and after treatment were recorded according to the Blauer adhesion score. Blood extracted for sacrifice was analyzed. Endometriotic lesions were evaluated for size, volume, histology, and immunohistochemistry (vascular endothelial growth factor [VEGF] and CD31). Significance level was accepted as p < 0.05. RESULTS: Aflibercept significantly reduced endometrial implant volume (p = 0.002). The explant epithelial histological score showed a significant difference between aflibercept and leuprolide acetate (p = 0.006) and between aflibercept and control groups (p = 0.002). Aflibercept decreased VEGF-H and CD31 expression (p = 0.001) more than leuprolide acetate. Aflibercept improved adhesions (p = 0.006). CONCLUSION: Aflibercept is more successful than leuprolide acetate in the treatment of endometriosis.


OBJETIVO: Mostrar por primera vez cómo afecta aflibercept a las lesiones de endometriosis. MATERIAL Y MÉTODOS: Endometriosis inducida quirúrgicamente en ratas hembras albinas Wistar. Las ratas con endometriosis se dividieron aleatoriamente en tres grupos: control (Co), aflibercept (Af) y acetato de leuprolida (Le). Luego, Af, aflibercept y Le recibieron acetato de leuprolida. El grupo de control no fue tratado. Los pesos y cambios en las adherencias intraabdominales de las ratas antes y después del tratamiento se registraron de acuerdo con la puntuación de adherencia de Blauer. La sangre extraída para el sacrificio fue analizada. Las lesiones endometriósicas se evaluaron en tamaño, volumen, histología e inmunohistoquímica (factor de crecimiento endotelial vascular [VEGF] y CD31). El nivel de significación se aceptó como p < 0.05. RESULTADOS: Aflibercept redujo significativamente el volumen del implante endometrial (p = 0.002). La puntuación histológica epitelial (EHS) del explante mostró una diferencia significativa entre aflibercept y acetato de leuprolida (p = 0.006) y entre los grupos de aflibercept y control (p = 0.002). Aflibercept disminuyó la expresión de VEGF-H y CD31 (p = 0.001) más que el acetato de leuprolida. Aflibercept mejoró las adherencias (p = 0.006). CONCLUSIÓN: Aflibercept tiene más éxito que el acetato de leuprolide en el tratamiento de la endometriosis.

RESUMO

The Bosma syndrome (BAMS: Bosma arhinia microphthalmia syndrome) is a condition first described in 1972. Since then, several reviews have published the cases looking for diagnostic criteria and associated genetic alterations. The mutation in the SMCHD1 gene (Structural Maintenance of Chromosomes flexible Hinge Domain containing protein 1) seems to explain a part of the development of the phenotype. Not all cases show the same alterations or meet the classic diagnostic criteria, and few have undergone genetic analysis. We present a case with a new variant in this gene and an update of the literature on this syndrome with the aim of improving the diagnosis and follow-up of these patients.

RESUMO

BACKGROUND: Early detection of suspected neurodevelopmental delay allows for timely diagnosis and appropriate intervention, for which numerous screening tests have been developed. However, most are complex and impractical for health-care workers at the community level. This study aimed to validate the KARVI scale in the neurodevelopment assessment of children under 1 year of age. METHODS: We conducted an observational, longitudinal, comparative, inferential, and prospective study. Healthy children without risk factors for developing neurodevelopmental delay from 0 to 12 months of age were evaluated remotely using the Zoom® application. The Child Development Evaluation Test and the KARVI scale were applied once a month for four consecutive months. RESULTS: Fifty individuals were analyzed, with a predominance of males in 52%. Adequate percentages for a screening test were obtained in the first evaluation with a sensitivity of 70% (confidence interval [CI] 95% 34.75-93.33) and a specificity of 75% (CI 95% 58.8-87.31), and in the fourth evaluation with a sensitivity of 100% (CI 95% 29.4-100) and a specificity of 78.72% (CI 95% 64.34-89.3), being significant in both evaluations (p = 0.007 and p = 0.001, respectively). CONCLUSIONS: The KARVI scale has the elements to be an effective screening test for suspected neurodevelopmental delay, but more extensive studies are needed to obtain more reliable results.


INTRODUCCIÓN: La identificación temprana de retraso en el neurodesarrollo permite un diagnóstico oportuno y una intervención apropiada. Para ello, se han creado diversas pruebas de tamizaje; sin embargo, la mayoría son complejas y poco prácticas para el personal de la salud a nivel comunitario. El objetivo del estudio fue realizar la validación de la escala KARVI en la valoración del neurodesarrollo en niños menores de un año. MÉTODOS: Se realizó un estudio observacional, longitudinal, comparativo inferencial y prospectivo, en el cual se evaluaron, vía remota mediante la aplicación Zoom®, niños sanos de 0 a 12 meses de edad sin factores de riesgo para desarrollar retraso en el neurodesarrollo. Se aplicaron la prueba EDI (Evaluación del Desarrollo Infantil) y la escala KARVI una vez al mes por cuatro meses consecutivos. RESULTADOS: Se analizaron 50 individuos, con predominio del sexo masculino en el 52%. Se obtuvieron porcentajes adecuados para una prueba de tamizaje tanto en la primera evaluación, con sensibilidad de 70% (IC 95% 34.75-93.33) y especificidad de 75% (IC 95% 58.8-87.31), como en la cuarta, con sensibilidad de 100% (IC 95% 29.4-100) y especificidad de 78.72% (IC 95% 64.34-89.3), con significación estadística en ambas evaluaciones (p = 0.007 y p = 0.001, respectivamente). CONCLUSIONES: Se considera que la escala KARVI cuenta con los elementos para considerarla como una prueba de tamizaje efectiva para detectar retraso del neurodesarrollo, sin embargo. Sin requieren estudios más extensos para obtener resultados más confiables.

RESUMO

Epithelial ingrowth is one of the most significant complications of Laser in Situ Keratomileusis (LASIK) refractive surgery. We present the case of a 72-year-old male with a history of myopic LASIK (1999), who underwent cataract surgery and a second thin LASIK sub-Bowman flap to correct refractive error. Then, three months after pars plana vitrectomy for an epiretinal membrane, the patient complained of progressive vision loss. A diffuse haze of the corneal stroma that did not exist before surgery was observed. As the main suspicion was epithelial ingrowth, the flap was lifted and meticulous de-epithelialization of the stromal bed was performed. Mitomycin C 0.02% was applied, the flap was sutured with 10-0 Nylon, and a bandage contact lens was placed. The epithelialization of the interface after vitrectomy in a patient with LASIK could occur even when it is a rare complication and without obvious flap traumatism.

RESUMO

Introducción: los objetivos fueron aportar datos de la evolución longitudinal del crecimiento y determinar la edad de la telarquia y menarquia en niñas adoptadas de Rusia. Material y métodos: estudio de cohorte prospectivo sobre 24 niñas rusas adoptadas en España entre 2002-2010 controladas durante doce años. Se recopilaron antecedentes adversos revisando los informes médicos preadoptivos. Se registraron estandarizadamente: peso, talla, perímetro cefálico y edad de la telarquia y menarquia. Los valores medios se compararon con estándares de referencia. Resultados: antecedentes principales: pretérmino (33,3%), bajo peso al nacer (41,7%), exposición prenatal al alcohol (45,8%), abuso/negligencia (54,2%). Evaluación inicial: edad media (DE), 3 (1,6) años; puntuación Z (pZ) peso, -1,35; pZ talla, -2,42; pZ perímetro cefálico, -1,77. Tras 1 año de la adopción, se observó crecimiento recuperador significativo del peso (pZ +0,68), talla (pZ +0,98) y perímetro cefálico (pZ +0,76). Tendencias temporales del crecimiento: no se observó retraso del peso desde los 7 años; la talla mantuvo recuperación hasta los 10 años (pZ -0,40) y se mantuvo estable hasta los 15 años (pZ -0,46); el grado de retraso de la talla siempre fue superior al del peso. Aparición de la telarquia: edad media (DE), 9,9 (0,8) años; talla 135,4 cm (pZ -0,43). Presentación de la menarquia: edad media (DE), 11,9 (0,7) años; talla 147,6 cm (pZ -0,44). Conclusiones: el patrón de crecimiento y desarrollo se caracterizó por un retraso severo de la talla y moderado del peso y perímetro cefálico en el momento de la adopción, un rápido, significativo y prolongado crecimiento recuperador, una aceleración del desarrollo puberal con telarquia y menarquia tempranas, y una incompleta recuperación de la talla.

Introduction: the objectives were to provide longitudinal data on growth and determine the age of thelarche and menarche in girls adopted from Russia. Material and methods: prospective cohort study in 24 girls from Russia adopted in Spain in the 2002-2010 period, who were followed up for 12 years. The history of adverse childhood experiences was collected by reviewing pre-adoption medical records. We recorded standardised measurements of weight, height and head circumference and the age at thelarche and menarche. The mean values were compared with reference standards. Results: Salient history: preterm birth (33.3%), low birth weight (41.7%), prenatal alcohol exposure (45.8%), abuse and neglect (54.2%). Initial evaluation: mean age, 3 years (standard deviation [SD] 1.6) years; weight z-score (z), −1.35; height z, −2.42; head circumference z −1.77. One year after adoption, there was significant catch-up growth in weight (z +0.68), height (z +0.98), and head circumference (z +0.76). Temporal trends in growth: no weight delay from age 7 years; height continued to recover until age 10 (z −0.40) and remained stable until age 15 (z −0.46); the delay was greater compared to weight at every timepoint. The mean age at onset of thelarche was 9.9 years (SD 0.8) with a height of 135.4 cm (z −0.43). The mean age at menarche was 11.9 years (SD 0.7) years, with a height of 147.6 cm (z −0.44). Conclusions: the pattern of growth and development was characterized by severe delay in linear growth and a moderate delay in weight and head circumference at the time of adoption, rapid, significant and prolonged catch-up growth, acceleration of pubertal development with early thelarche and menarche and an incomplete recovery of linear growth.

RESUMO

Objectives Interplay of Factor XIIIa (FXIIIa), a transglutaminase, responsible for cross-linking of matrix proteins, Matrix Metalloproteinase-9 (MMP-9), a gelatinase, and Vascular Endothelial Growth Factor (VEGF), an angiogenic inducer, were studied in relation to fibrogenesis and disease progression in oral submucous fibrosis (OSMF). Material and methods Immunohistochemical expression of markers was studied in 60 formalin-fixed paraffin-embedded tissue blocks of OSMF and 20 normal oral mucosal tissues. FXIIIa was studied quantitatively while MMP-9 and VEGF were assessed semi-quantitatively. Expression was compared with histopathological grades of OSMF. Results FXIIIa expression significantly increased in OSMF (p-value 0.000). However, expression decreased and cells became quiescent with increasing grades (p-value 0.000). MMP-9 (p-value epithelium 0.011, p-value connective tissue 0.000) and VEGF expression (p-value epithelium 0.000, connective tissue 0.000) increased in OSMF. A negative correlation between FXIIIa and MMP-9 (−0.653) in early grade (p-value of 0.021) and a positive correlation between FXIIIa and VEGF (0.595) (p-value of 0.032) was found in the moderate grade OSMF. Regression analysis showed a significant association (p<0.01) of FXIIIa in OSMF and with increasing grades of OSMF. Conclusion FXIIIa may play a crucial role in initiation of fibrosis in OSMF. MMP-9 may have a diverse role to play in OSMF as a regulator of fibrosis. VEGF may show an angio-fibrotic switch and contribute to fibrosis in OSMF. These cytokines may show altered function and can contribute to fibrosis and chronicity of disease due to changes in the microenvironment. Tissue stiffness in OSMF itself creates an environment that enhances the chronicity of the disease. (AU)


Objetivos Se estudió la interacción del factor XIIIa (FXIIIa), una transglutaminasa responsable de los entrecruzamientos de las proteínas de la matriz, la metaloproteinasa de matriz-9 (MMP-9), una gelatinasa y el factor de crecimiento endotelial vascular (VEGF), un inductor angiogénico, en relación con la fibrogénesis y la progresión de la enfermedad en la fibrosis submucosa oral (OSMF). Material y métodos Se estudió la expresión inmunohistoquímica de marcadores en 60 bloques de tejido de OSMF fijados con formalina e incluidos en parafina y 20 tejidos de mucosa oral normales. FXIIIa se estudió cuantitativamente mientras que MMP-9 y VEGF se evaluaron semicuantitativamente. La expresión se comparó con los grados histopatológicos de OSMF. Resultados La expresión de FXIIIa aumentó significativamente en OSMF (valor de p 0,000). Sin embargo, la expresión disminuyó y las células se volvieron inactivas a medida que aumentaban los grados (valor de p 0,000). MMP-9 (valor de p epitelio 0,011, tejido conectivo valor de p 0,000) y expresión de VEGF (valor de p epitelio 0,000, tejido conectivo 0,000) aumentaron en OSMF. Se encontró una correlación negativa entre FXIIIa y MMP-9 (-0,653) en grado temprano (valor de p de 0,021) y una correlación positiva entre FXIIIa y VEGF (0,595) (valor de p de 0,032) en OSMF de grado moderado. El análisis de regresión mostró una asociación significativa (p<0,01) de FXIIIa en OSMF y con grados crecientes de OSMF. Conclusión FXIIIa puede desempeñar un papel crucial en el inicio de la fibrosis en OSMF. MMP-9 puede desempeñar un papel diverso en OSMF como regulador de la fibrosis. VEGF puede mostrar un interruptor angiofibrótico y contribuir a la fibrosis en OSMF. Estas citocinas pueden mostrar una función alterada y pueden contribuir a la fibrosis y la cronicidad de la enfermedad debido a cambios en el microambiente. La rigidez del tejido en el propio OSMF crea un entorno que mejora la cronicidad de la enfermedad. (AU)

RESUMO

Objective: To review current scientific evidence on the physiological effects of kangaroo care, explore barriers and facilitators to its implementation, and identify areas requiring further research. Materials and methods: An integrative review was conducted using PubMed, Scopus, Web of Science, and Cochrane databases without language restrictions. Studies included quantitative and qualitative review studies. Critical appraisal of studies was performed using the Joanna Briggs Institute tool. Results: Sixteen studies were analyzed, providing heterogeneous support for the efficacy of kangaroo care  in improving various neonatal physiological parameters including heart rate, body temperature, and oxygen saturation. Major barriers to implementation included restricted visiting hours, healthcare staff workload, negative cultural beliefs, lack of information and empowerment for mothers, and limited involvement of fathers. Conclusions: kangaroo care positively impacts premature or low birth weight neonatal development, though implementation is influenced by sociocultural factors. Further research is needed to better assess real effects on neonatal physiological parameters. Additional qualitative studies could aid in developing culturally adapted strategies to optimize kangaroo care implementation across contexts by better understanding family and medical team perspectives.

RESUMO

Introduction The growth hormone (GH) has been reported as a crucial neuronal survival factor in the hippocampus against insults of diverse nature. Status epilepticus (SE) is a prolonged seizure that produces extensive neuronal cell death. The goal of this study was to evaluate the effect of intracerebroventricular administration of GH on seizure severity and SE-induced hippocampal neurodegeneration. Methodology Adult male rats were implanted with a guide cannula in the left ventricle and different amounts of GH (70, 120 or 220 ng/3 μl) were microinjected for 5 days; artificial cerebrospinal fluid was used as the vehicle. Seizures were induced by the lithium–pilocarpine model (3 mEq/kg LiCl and 30 mg/kg pilocarpine hydrochloride) one day after the last GH administration. Neuronal injury was assessed by Fluoro-Jade B (F-JB) staining. Results Rats injected with 120 ng of GH did not had SE after 30 mg/kg pilocarpine, they required a higher number of pilocarpine injections to develop SE than the rats pretreated with the vehicle, 70 ng or 220 ng GH. Prefrontal and parietal cortex EEG recordings confirmed that latency to generalized seizures and SE was also significantly higher in the 120 ng group when compared with all the experimental groups. FJ-B positive cells were detected in the hippocampus after SE in all rats, and no significant differences in the number of F-JB cells in the CA1 area and the hilus was observed between experimental groups. Conclusion Our results indicate that, although GH has an anticonvulsive effect in the lithium–pilocarpine model of SE, it does not exert hippocampal neuroprotection after SE. (AU)


Introducción La hormona de crecimiento (HC) es un factor que favorece la supervivencia neuronal en el hipocampo ante agresiones de diversa naturaleza. El status epilepticus (SE) es un tipo de crisis epiléptica de larga duración que produce muerte neuronal. El objetivo de este estudio fue evaluar el efecto de la administración intracerebroventricular de HC en la severidad de las convulsiones y la neurodegeneración hipocampal debida al SE. Metodología A ratas macho adultas se les implantó una cánula guía en el ventrículo lateral izquierdo y se les microinyectaron diferentes cantidades de HC (70, 120 o 220 ng/3 μl) durante 5 días; como vehículo se inyectó líquido cefalorraquídeo artificial. Las convulsiones se generaron con el modelo de litio-pilocarpina (3 mEq/kg LiCl y 30 mg/kg clorhidrato pilocarpina) un día después de la última inyección de HC. La neurodegeneración se identificó con la tinción de Fluoro-Jade B (F-JB). Resultados Las ratas a las que se les inyectaron 120 ng de HC requirieron 2 o 3 inyecciones de pilocarpina para desarrollar SE, en comparación con el resto de los grupos experimentales que requirieron solo una aplicación del convulsivante. Los registros EEG de la corteza prefrontal y parietal confirmaron que la latencia a las crisis generalizadas y al SE fue mayor en dicho grupo experimental. Todas las ratas con SE presentaron células positivas al FJ-B en el área CA1 e hilus del hipocampo, y no se identificaron diferencias entre los tratamientos. Conclusión Nuestros resultados muestran que, aunque la HC tiene un efecto anticonvulsivante, una vez que se ha desarrollado el SE no promueve neuroprotección en el hipocampo. (AU)

RESUMO

OBJECTIVES: Interplay of Factor XIIIa (FXIIIa), a transglutaminase, responsible for cross-linking of matrix proteins, Matrix Metalloproteinase-9 (MMP-9), a gelatinase, and Vascular Endothelial Growth Factor (VEGF), an angiogenic inducer, were studied in relation to fibrogenesis and disease progression in oral submucous fibrosis (OSMF). MATERIAL AND METHODS: Immunohistochemical expression of markers was studied in 60 formalin-fixed paraffin-embedded tissue blocks of OSMF and 20 normal oral mucosal tissues. FXIIIa was studied quantitatively while MMP-9 and VEGF were assessed semi-quantitatively. Expression was compared with histopathological grades of OSMF. RESULTS: FXIIIa expression significantly increased in OSMF (p-value 0.000). However, expression decreased and cells became quiescent with increasing grades (p-value 0.000). MMP-9 (p-value epithelium 0.011, p-value connective tissue 0.000) and VEGF expression (p-value epithelium 0.000, connective tissue 0.000) increased in OSMF. A negative correlation between FXIIIa and MMP-9 (-0.653) in early grade (p-value of 0.021) and a positive correlation between FXIIIa and VEGF (0.595) (p-value of 0.032) was found in the moderate grade OSMF. Regression analysis showed a significant association (p<0.01) of FXIIIa in OSMF and with increasing grades of OSMF. CONCLUSION: FXIIIa may play a crucial role in initiation of fibrosis in OSMF. MMP-9 may have a diverse role to play in OSMF as a regulator of fibrosis. VEGF may show an angio-fibrotic switch and contribute to fibrosis in OSMF. These cytokines may show altered function and can contribute to fibrosis and chronicity of disease due to changes in the microenvironment. Tissue stiffness in OSMF itself creates an environment that enhances the chronicity of the disease.

RESUMO

Introduction: The objective of this study is to contribute data on the temporal trends in weight, height, body mass index (BMI) and head circumference (HC) in boys adopted from Russia. Material and methods: Prospective observational study on an initial cohort of 139 Russian boys adopted in Spain between 2001 and 2013. Adverse history was collected by reviewing pre-adoption medical records. Anthropometric parameters were measured and recorded in a standardized way. The measurements obtained were compared with the World Health Organization child growth standards, calculating the corresponding z-scores (Z) and percentiles for age and sex. Results: Main history: preterm (32.4%), low birth weight (26.6%), prenatal alcohol exposure (19.4%), abandonment at birth (56.1%), abuse/neglect (49.3%). Initial post-arrival evaluation, 3 (1.7) years: weight Z, -1.24; height Z, -2.34; HC Z, -1.27. Significant catch-up growth (Z increase) in the first year: weight, +0.73; height, +1.05; HC, +0.6; in the second year: height, +0.58. Longitudinal growth pattern. Weight: from age 5 years, no relevant differences were observed. Height: at age 6 years a relevant delay persisted, from ages 7 to 11 years a gradual increase was observed, and from ages 12 to 17 years a gradual decrease, no showing relevant differences. BMI: showed that the degree of height delay was always higher than that of weight, balancing after age 14 years. HC: at age 5 years, there was no longer a relevant difference. Conclusions: These findings suggest that, despite the important delay of weight, HC, and especially height at the time of adoption, and the various adverse factors for growth that they presented, international adoption led to a substantial recovery of all anthropometric parameters, showing plasticity in the physical growth of these children.

Introducción: El objetivo de este estudio es aportar datos sobre las tendencias temporales en peso, talla, índice de masa corporal (IMC) y perímetro cefálico (PC) en niños varones adoptados de Rusia. Material y métodos: Estudio observacional prospectivo sobre una cohorte inicial de 139 niños rusos adoptados en España entre los años 2001-2013. Se recopilaron antecedentes adversos revisando los informes médicos preadoptivos. Los parámetros antropométricos se midieron y registraron estandarizadamente. Las mediciones obtenidas se compararon con los estándares de crecimiento infantil de la Organización Mundial de la Salud, calculando las correspondientes puntuaciones Z (Z) y los percentiles para edad y sexo. Resultados: Antecedentes principales: pretérmino (32,4%), bajo peso al nacer (26,6%), exposición prenatal al alcohol (19,4%), abandono al nacimiento (56,1%), abuso/negligencia (49,3%). Evaluación inicial post-llegada, 3 (1,7) años: Z peso, -1,24; Z talla, -2,34; Z PC, -1,27. Crecimiento recuperador significativo (incremento Z) en el primer año: peso, +0.73; talla, +1.05; PC, +0.6; en el segundo año: talla, +0.58. Patrón de crecimiento longitudinal. Peso: desde los 5 años de edad no se observaron diferencias relevantes. Talla: a los 6 años de edad persistía retraso relevante, desde los 7 hasta los 11 años se observó aumento paulatino, y desde los 12 hasta los 17 años una disminución gradual, sin mostrar diferencias relevantes. IMC: mostró que el grado de retraso de la talla fue superior al del peso, equilibrándose a partir de los 14 años de edad. PC: a los 5 años de edad no se observó diferencia relevante. Conclusiones: Estos hallazgos sugieren que, a pesar del importante retraso del peso, PC y especialmente de la talla en el momento de la adopción, y de los diversos factores adversos para el crecimiento que presentaban, la adopción internacional condujo a una recuperación sustancial de todos los parámetros antropométricos ...

Abstract Objective To evaluate a fixed UV-C light emitting device for its antimicrobial effectiveness in the disinfection of distinct surfaces and its antifungal effectiveness on air quality in the hospital environment. Methods This quasi-experimental study was conducted in a hospital inpatient unit, in which a six-stage air Biosampler (Andersen®) was used for air analysis. In the evaluation of surfaces, three suspensions of microorganisms (Acinetobacter sp. multidrug-resistant, Escherichia coli, and KPC-producing Klebsiella pneumoniae) were used to contaminate the environment. In both evaluations, pre- (control) and post-activation of UV-C light (test) collections were made. Results In the air evaluation, an important reduction was observed in the colony count after irradiation with UV-C light, and pathogenic or toxigenic fungi were not found in either of the two moments. Regarding the disinfection of surfaces, no bacterial growth was observed after the application of UV-C light, showing 100% bacterial inactivation under the tested conditions. Conclusion The use of fixed UV-C light emission technology was effective and can be considered a promising intervention for hospital surface disinfection protocols.
