Latent transition analysis on post-traumatic stress and post-traumatic growth among firefighters.

Background: Firefighters, in the course of their professional responsibilities, confront an array of stressors contingent upon the distinctive characteristics of their duties.Objective: This study investigated the longitudinal impact of trauma incidents during duty on firefighters using latent transition analysis.Method: Data from 346 firefighters in South Korea who had experienced trauma events while on duty were utilized. Initially, latent groups were identified based on the relationship between post-traumatic stress disorder (PTSD) and post-traumatic growth (PTG). Groups were labelled based on the analysis of differences in PTSD, mental health, and growth-related factors among classified groups. Subsequently, transition probabilities and patterns from Time 1 to Time 2 were examined, followed by an investigation into variances based on demographic factors (gender, age) and occupational factors (work experience, shift pattern) using variance analysis and multinomial logistic regression analysis.Results: First, at Time 2, a five-group model was classified into 'Growth,' 'Resilience or Numbness,' 'Struggle,' 'Partial Struggle,' and 'PTSD' groups. Second, upon examining the transition patterns between latent groups, four patterns emerged: 'continued distress,' 'growth,' 'adaptation,' and 'escalated distress.' Third, the 'Struggle' group showed a 0% probability of transitioning to the 'Growth' group, whereas it displayed the highest probability among the groups transitioning to the 'PTSD' group. Fourth, latent transition analysis results showed a strong tendency for the 'Growth' group and 'Resilience or Numbness' group to remain in the same category. Fifth, age was found to be a significant factor affecting the transition of latent groups.Conclusion: This research represents the inaugural attempt to longitudinally investigate the interplay between PTSD and PTG among firefighters.

Impact on neonatal morbidity of moderate to severe early foetal growth restriction defined by doppler criteria: multicentre study.

INTRODUCTION: In recent years, there has been a change in the conceptualization of foetal growth restriction (FGR), which has gone from being defined solely based on weight criteria to being defined and staged based on Doppler criteria. The aim of our study was to evaluate neonatal risk in a cohort of neonates with moderate to severe early-onset FGR defined by Doppler criteria. POPULATION AND METHODS: We conducted a multicentre prospective cohort study in a cohort of neonates with early-onset foetal growth restriction and abnormal Doppler findings and a control cohort without Doppler abnormalities matched for sex and gestational age. RESULTS: A total of 105 patients (50 cases, 55 controls) were included. We found a higher frequency of respiratory morbidity in the FGR group, with an increased need of surfactant (30% vs. 27.3%; OR, 5.3 [95% CI, 1.1-26.7]), an increased need for supplemental oxygen (66% vs. 49.1%; OR, 5.6 [95% CI, 1.5-20.5]), and a decreased survival without bronchopulmonary dysplasia (70 vs. 87.3%; OR, 0.16 [95% CI, 0.03-0.99]). Patients with FGR required a longer length of stay and more days of parenteral nutrition and had a higher incidence of haematological abnormalities such as neutropenia and thrombopenia. The lactate level at birth was higher in the severe FGR subgroup (6.12 vs. 2.4 mg/dL; P = .02). CONCLUSION: The diagnosis of early-onset moderate to severe FGR defined by Doppler criteria carries a greater risk of respiratory, nutritional and haematological morbidity, independently of weight and gestational age. These patients, therefore, should be considered at increased risk compared to constitutionally small for gestational age preterm infants or preterm infants without FGR.

Small for gestational age: concept, diagnosis and neonatal characterization, follow-up and recommendations.

Newborns who do not reach a weight appropriate for their gestational age and sex can be classified in different ways. This article defines the concepts of small for gestational age (SGA) and intrauterine growth restriction, as well as the underlying causes of these conditions, with the goal of establishing consensus definitions for these patients, in whom treatment with growth hormone throughout childhood may be indicated and who may be at risk of developing endocrine or metabolic disorders in puberty and adulthood. Most SGA children experience spontaneous catch-up growth that is usually completed by age 2 years. In SGA children who remain short, treatment with recombinant human growth hormone is effective, increasing adult height. Small for gestational age infants with rapid catch-up growth and marked weight gain are at increased risk of premature adrenarche, early puberty, polycystic ovary syndrome (girls), insulin resistance and obesity, all of which are risk factors for type 2 diabetes and metabolic syndrome in adulthood. The SGA status can affect different areas of neurodevelopment and manifest at different stages in life; neurodevelopmental outcomes are better in SGA infants with spontaneous catch-up growth. Due to the potential risks associated with SGA, adequate characterization of these patients at birth is imperative, as it allows initiation of appropriate follow-up and early detection of abnormalities.

Combined effect of compassionate and uncompassionate self-responding on Chinese college students' mental health during the initial wave of the COVID-19 pandemic: a response surface analysis.

Background: The initial wave of the COVID-19 pandemic significantly deteriorated mental health, especially among college students. Self-compassion has demonstrated benefits for psychological outcomes such as depressive symptoms, life satisfaction, posttraumatic stress symptoms (PTSS), and posttraumatic growth (PTG). Notably, existing literature suggests that the protective and vulnerable aspects within the Self-Compassion Scale, namely, compassionate and uncompassionate self-responding (CSR and USR), can coexist within individuals and influence their mental health through various coexisting patterns. However, this process has not been sufficiently explored.Objective: This study aimed to explore the combined effects of CSR and USR on college students' depressive symptoms, life satisfaction, PTSS, and PTG during the initial wave of the pandemic.Method: In this cross-sectional study, 4450 Chinese college students (51.9% females, Mage = 20.58 years, SD = 1.49) completed self-report measures amid the COVID-19 pandemic's initial wave in 2020. Response surface analyses were utilised to investigate the combined effects of CSR and USR.Results: Simultaneously increased CSR and USR were associated with a slight increase in depressive symptoms, PTSS, and life satisfaction, but a substantial increase in PTG. Conversely, increased CSR and decreased USR were associated with a considerable decrease in depressive symptoms and PTSS, a significant increase in life satisfaction, and a moderate increase in PTG.Conclusions: CSR and USR demonstrated protective and vulnerable impacts, respectively. It is imperative to analyse their combined effects as an interactive system and consider the specific characteristics of different psychological responses.

Increased CSR and decreased USR were associated with less depressive symptoms and PTSS as well as more life satisfaction.CSR mitigated the negative effects of USR on depressive symptoms, life satisfaction, and PTSS.Simultaneously increased CSR and USR were associated with a substantial increase in PTG.

Effect of a Dose-Dependent Administration of Binge Alcohol on the Mandible in the Adolescent Sprague Dawley Rat

SUMMARY: Binge drinking in adolescents has a negative effect on the developing skeleton and the attainment of peak bone mass. Our study aimed to examine the effect of binge drinking on the growth and functional integrity of the adolescent Sprague Dawley rat mandible and to determine if a dosage of 1.5 g/kg is sufficient to produce a binge-model of consumption. A total of eight 7-week-old adolescent (male) Sprague Dawley rats were randomly placed into 4 groups with two rats each: 1-week alcohol-exposed rats, 1-week pair- fed control rats, 4-week alcohol-exposed rats and 4-week pair-fed control rats. The alcohol exposed groups were administered a single daily dose via oral gavage of 1.5 g/kg of 20 % alcohol 3 days a week (alternate days) for 7 or 28 days. The pair-fed control groups were administered a caloric equivalent dose of maltose dextrin via oral gavage on the same days as the alcohol-exposed rats. The one-week alcohol exposed, and control rats were terminated on day 7 and the four-week alcohol exposed and control rats on day 28. The mandibles were dissected out and osteometric measurements determined using a digital vernier caliper. Bones were scanned using a 3D-microCT scanner (Nikon XTH 255L). Biomechanical tests were done using a Shimadzu universal testing machine. Differences observed were regarding mandibular osteometry, which showed a reduced height in the central portion of the alveolar bone (Al'-Me), and an increase in the height of the condylar head (Cd-Ag) in the 1-week alcohol-exposed rats when compared to the 1-week pair-fed control rats. No other differences were noted. Lack of significant changes seen between the alcohol and pair-fed control groups in both acute binge and chronic binge exposed rats is likely due to the low dose of alcohol administered to the rats in the study thus a higher dose is proposed.

El consumo excesivo de alcohol en adolescentes tiene un efecto negativo en el desarrollo del esqueleto y en la consecución de la masa ósea máxima. Nuestro estudio tuvo como objetivo examinar el efecto del consumo excesivo de alcohol sobre el crecimiento y la integridad funcional de la mandíbula de la rata adolescente Sprague Dawley y determinar si una dosis de 1,5 g/kg es suficiente para producir un modelo de consumo compulsivo. Un total de ocho ratas Sprague Dawley adolescentes (machos) de 7 semanas de edad se colocaron aleatoriamente en 4 grupos con dos ratas cada uno: ratas expuestas al alcohol durante 1 semana, ratas de control alimentadas en parejas durante 1 semana, ratas expuestas al alcohol durante 4 semanas, y ratas de control alimentadas en parejas durante 4 semanas. A los grupos expuestos al alcohol se les administró una dosis única diaria mediante sonda oral de 1,5 g/kg de alcohol al 20 % 3 días a la semana (días alternos) durante 7 o 28 días. A los grupos de control alimentados por parejas se les administró una dosis calórica equivalente de maltosa dextrina mediante sonda oral los mismos días que a las ratas expuestas al alcohol. Las ratas expuestas al alcohol durante una semana, las ratas de control al día 7, las ratas expuestas al alcohol durante cuatro semanas y las ratas de control al día 28. Se diseccionaron las mandíbulas y se determinaron las mediciones osteométricas utilizando un calibre vernier digital. Los huesos se escanearon utilizando un escáner 3D-microCT (Nikon XTH 255L). Las pruebas biomecánicas se realizaron utilizando una máquina de pruebas universal Shimadzu. Las diferencias observadas se relacionaron con la osteometría mandibular, que mostró una altura reducida en la porción central del hueso alveolar (Al'-Me) y un aumento en la altura de la cabeza condilar (Cd-Ag) en las ratas expuestas al alcohol durante una semana, en comparación con las ratas control alimentadas en parejas durante una semana. No se observaron otras diferencias. La falta de diferencias significativas entre los grupos de alcohol y de control alimentados en parejas expuestas a ebriedad aguda y ebriedad crónica, probablemente se deba a la baja dosis de alcohol administrada a las ratas en el estudio, por lo que se propone una dosis más alta.

Composition of the microbiota in patients with growth hormone deficiency before and after treatment with growth hormone.

INTRODUCTION: Growth hormone (GH) and insulin-like growth factor-1 (IGF-1) have modulatory effects on bowel function and its microbiota. Our aim was to investigate whether low levels of GH and IGF-1 in patients with GH deficiency are associated with changes in gut physiology/integrity as well as in the composition of the gut microbiota. MATERIALS AND METHODS: We conducted a case-control study in 21 patients with GH deficiency, at baseline and after 6 months of GH treatment, and in 20 healthy controls. We analysed changes in anthropometric and laboratory characteristics and bacterial translocation and studied the composition of the microbiome by means of massive 16S rRNA gene sequencing. RESULTS: Growth hormone deficiency was accompanied by a significant increase in serum levels of sCD14, a marker of bacterial translocation (P < .01). This increase was reversed by GH treatment. We did not find any differences in the composition or α- or ß-diversity of the gut microbiota after treatment or between cases and controls. CONCLUSIONS: Our work is the first to demonstrate that the presence of GH deficiency is not associated with differences in gut microbiota composition in comparison with healthy controls, and changes in microbiota composition are also not found after 6 months of treatment. However, GH deficiency and low IGF-1 levels were associated with an increase in bacterial translocation, which had reversed after treatment.

Experience with the use of intravitreal bevacizumab in cases with type I retinopathy of prematurity in a Latin American country.

In retinopathy of prematurity (ROP) type I, the use of intravitreal bevacizumab (IVB), which is an inhibitor of endothelial growth factor (VEGF), has become popular despite not being a therapy approved by regulatory agencies. However, IVB has shown positive effects in halting disease progression at lower costs compared to other anti-VEGF therapies (ranibizumab or aflibercept). In this report, we present the experience during the treatment with IVB of 102 Colombian children with ROP type I, with a success rate of 98% (100). Complications occurred in 3.9% (4). Finally, we conclude that a single dose of IVB is an effective therapy for the management of ROP type I, with a lower risk of complications and retreatment.

Potentially morally injurious experiences and associated factors among Dutch UN peacekeepers: a latent class analysis.

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.

Comparative analysis of foetal and neonatal growth curves.

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.

The association of cadmium heavy metal with growth failure in children: A systematic review and meta-analysis.

Introduction: Introduction: early exposure to cadmium toxic metal has been suggested to be associated with reduced infants/children growth; nevertheless, the available evidence is contradictory. Objective: this meta-analysis aimed to examine the association of cadmium exposure through biological samples to growth measurements of infants/children, including body weight, height, body mass index (BMI), BMI-for-age (BMI Z-score), weight-for-age (WAZ), height-for-age (HAZ), and weight-for-height (WHZ) z-scores. Methods: a systematic search in PubMed and Scopus was implemented to obtain the related studies. The standardized beta coefficients (ß) and 95 % confidence intervals (95 % CI) were used as effect sizes to test the associations using the random effects analysis. Results: a total of 15 studies with 6,181 participants were included in the meta-analysis. In the overall analysis, pooled analysis of available data revealed that cadmium exposure was inversely linked to height (ß = -0.06, 95 % CI = -0.12 to -0.01) and WAZ (ß = -0.01, 95 % CI = -0.02 to -0.003). These relationships were also supported by prospective cohort studies and urinary cadmium exposure. In the stratified analysis, cadmium exposure was negatively linked to the weight of children in prospective cohort studies, in studies that assessed urinary cadmium exposure. No significant association was detected between cadmium exposure and BMI, BMI Z-score, WHZ, and HAZ in the overall and subgroup analyses. Conclusions: this meta-analysis emphasized the importance of cadmium exposure as a risk factor for growth failure in infants/children.

Introducción: Introducción: se ha sugerido que la exposición temprana al metal tóxico cadmio se asocia a un crecimiento reducido de los bebés y niños; sin embargo, la evidencia disponible es contradictoria. Objetivo: este metanálisis tuvo como objetivo examinar la asociación de la exposición al cadmio a través de muestras biológicas con las mediciones de crecimiento de bebés/niños, incluidos el peso corporal, la altura, el índice de masa corporal (IMC), el IMC para la edad (puntuación Z del IMC) y las puntuaciones z de peso para la edad (WAZ), altura para la edad (HAZ) y peso para la altura (WHZ). Métodos: se implementó una búsqueda sistemática en PubMed y Scopus para obtener los estudios relacionados. Los coeficientes beta estandarizados (ß) y los intervalos de confianza del 95 % (IC 95 %) se utilizaron como tamaños del efecto para probar las asociaciones mediante el análisis de efectos aleatorios. Resultados: se incluyeron en el metanálisis un total de 15 estudios, con 6.181 participantes. En el análisis general, el análisis conjunto de los datos disponibles reveló que la exposición al cadmio estaba inversamente relacionada con la altura (ß = -0,06, IC del 95 % = -0,12 a -0,01) y WAZ (ß = -0,01, IC del 95 % = -0,02 a -0,003). Estas relaciones también fueron respaldadas por estudios de cohortes prospectivos y exposición al cadmio en orina. En el análisis estratificado, la exposición al cadmio se relacionó negativamente con el peso de los niños en estudios de cohortes prospectivos, en estudios que evaluaron la exposición al cadmio en la orina. No se detectó ninguna asociación significativa entre la exposición al cadmio y el IMC, la puntuación Z del IMC, el WHZ y el HAZ en los análisis generales y de subgrupos. Conclusiones: este metanálisis enfatizó la importancia de la exposición al cadmio como factor de riesgo del retraso del crecimiento en lactantes/niños.

Turning pain into strength: prosocial behaviours in coping with trauma.

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.

Prosocial behaviour can potentially serve as a beneficial strategy for individuals coping with trauma.Prosocial behaviour relieved the impact of trauma on meaning.Prosocial-themed intervention reduced PTSD and enhanced PTG in victims (based on effect size results).

Stress and Post-traumatic Growth of people with cancer: identification of associated factors / Estrés y Crescimiento Postraumático de personas con cáncer: identificación de factores asociados

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)

Evaluación de los cambios faciales y dentoalveolares en pacientes tratados con Twin block Modificado: resultados preliminares / Evaluation of facial and dentoalveolar changes in patients treated with modified twin block: preliminary results

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)

Crecimiento físico y aptitud física de nadadores y no nadadores de una región del Perú / Physical growth and fitness of swimmers and non-swimmers in a Peruvian region

Introducción: La evaluación del crecimiento físico y la aptitud física es considerada una tarea beneficiosa para la salud y del rendimiento deportivo. Objetivo: Comparar el crecimiento físico y la aptitud física de jóvenes nadadores y no-nadadores de una región del Perú. Metodología: Se efectuó un estudio descriptivo (comparativo) en niños y adolescentes de 6 a 13 años. Se conformó dos grupos de estudio. Grupo 1: Practicantes de natación (nadadores) y Grupo 2: No-practicantes de natación (no-nadadores). Se evaluó las medidas antropométricas de peso, estatura, circunferencia de la cintura (CC) y las pruebas físicas de salto horizontal (SH) y agilidad. Se calculó el Índice de Masa Corporal (IMC) y el estado de madurez. Resultados: No hubo diferencias en el peso y estatura entre ambos grupos en todos los rangos de edad (p>0,05). En la CC, los nadadores de ambos sexos mostraron valores inferiores en relación a los no-nadadores al menos desde los 6-7 años, 8-9 años y 10-11 años (p<0,05). En las pruebas físicas, no hubo diferencias en la agilidad entre ambos grupos (p>0,05), sin embargo, en el SH, los nadadores mostraron mejor despeño que sus similares no-nadadores (P<0,05), en los hombres a los 10-11 años y 12-13 años (p<0,05) y en las mujeres en todos los rangos de edad (p<0,05). Conclusión: Los jóvenes nadadores y no-nadadores presentaron un similar patrón de crecimiento físico en peso y estatura, excepto en la CC, donde los no-nadadores mostraron valores superiores. En las pruebas físicas, ambos grupos evidenciaron similares valores de agilidad en todos los rangos de edad y los nadadores mostraron mejores resultados en el SH que sus similares no nadadores. Estos resultados sugieren la práctica de la natación de tres veces por semana, lo que podría ayudar a mantener un adecuado perfil antropométrico y mejorar la fuerza de los miembros inferiores.(AU)

Introduction: The evaluation of physical growth and fit-ness is considered a beneficial task for health and sports per-formance.Objective: To compare the physical growth and fitness ofyoung swimmers and non-swimmers in a region of Peru Methodology: A descriptive (comparative) study was car-ried out in children and adolescents aged 6 to 13 years. Twostudy groups were formed. Group 1: Swimming practitioners(swimmers) and Group 2: Non-swimming practitioners (non-swimmers). Anthropometric measurements of weight, height,sitting height, waist circumference (WC) and the physicaltests of horizontal jump (HH) and agility were evaluated.Body Mass Index (BMI) and maturity status were calculated.Significant differences were determined by means of the “t”test for independent samples.Results: There were no differences in weight, sittingheight and height between both groups in all age ranges(p>0.05). In CC, swimmers of both sexes showed lower val-ues in relation to non-swimmers at least from 6-7 years, 8-9years and 10-11 years (p<0.05). In the physical tests, therewere no differences in agility between both groups (p>0.05),however, in the SH, swimmers showed better performancethan their similar non-swimmers (P<0.05), in males at 10-11years and 12-13 years (p<0.05) and in females in all ageranges (p<0.05).Conclusion: Young swimmers and non-swimmers pre-sented a similar pattern of physical growth in weight andheight, except in CC, where non-swimmers showed highervalues. In the physical tests, both groups evidenced similaragility values in all age ranges and swimmers showed betterresults in SH than their similar non-swimmers. These resultssuggest that the practice of swimming three times a week hasa positive role on the anthropometric profile, adipose andlower limb strength performance.(AU)

Somatic Maturity and Physical Performance in Male Youth Players from a Professional Soccer Academy / Madurez Somática y Rendimiento Físico en Jugadores Juveniles Masculinos de una Academia de Fútbol Profesional

SUMMARY: The aim was to analyze the relationship between somatic maturation and physical performance in male youth soccer players belonging to a professional Mexican academy. In 121 male soccer aged 11 to 16 years from a professional academy the peak height velocity (PHV), percentage of adult height (PAS), jump capacity, sprint, intermittent speed and muscle mass were estimated. ANOVA was conducted to compare performance variables among maturity somatic categories and percentiles were calculated based on maturity offset using LMS method. Furthermore, a general linear model was employed to determine the explanatory variables for performance. Post-PHV soccer players demonstrated superior physical performance across several tests compared to Pre-PHV (p<0.001) and Circa-PHV (p<0.001) players. The smoothed percentile values of performance tests, based on somatic maturation, indicated progressive performance enhancement as individuals approached PHV (-2 to 2 years from PHV) (p<0.005). PHV was associated with jump capacity (p<0.001) and intermittent speed (p=0.007) while PAS was associated with time in sprint (p=.0004). In conclusion PHV and PAS explained better performance than chronological age, body composition characteristics, injuries, or training factors.

El objetivo fue analizar la relación entre la maduración somática y el rendimiento físico en futbolistas juveniles masculinos pertenecientes a una academia profesional mexicana. Métodos. En 121 futbolistas masculinos de 11 a 16 años de una academia profesional se estimó la velocidad máxima en altura (VPH), porcentaje de altura adulta (PAS), capacidad de salto, sprint, velocidad intermitente y masa muscular. Se realizó ANOVA para comparar variables de desempeño entre categorías somáticas de madurez y se calcularon percentiles en función de la compensación de madurez utilizando el método LMS. Además, se empleó un modelo lineal general para determinar las variables explicativas del desempeño. Los jugadores de fútbol post-PHV demostraron un rendimiento físico superior en varias pruebas en comparación con los jugadores Pre-PHV (p<0,001) y Circa-PHV (p<0,001). Los valores percentiles suavizados de las pruebas de rendimiento, basados en la maduración somática, indicaron una mejora progresiva del rendimiento a medida que los individuos se acercaban al PHV (-2 a 2 años desde el PHV) (p<0,005). PHV se asoció con la capacidad de salto (p<0,001) y velocidad intermitente (p=0,007) mientras que PAS se asoció con el tiempo en sprint (p=0,0004). En conclusión PHV y PEA explicaron un mejor rendimiento que la edad cronológica, las características de composición corporal, las lesiones o los factores de entrenamiento.

Resultados obstétricos y perinatales tras la muerte fetal de un solo gemelo en un embarazo monocorial biamniótico: reporte de caso y revisión bibliográfica

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)

Peso al nacer en el noroeste argentino. Comparación con una referencia nacional y un estándar internacional / Birth weight in the Northwest region of Argentina. Comparison with a national reference and an international standard

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.

Severe epithelial ingrowth after pars plana vitrectomy ten years after LASIK relifting.

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.

Kangaroo care: Benefits, challenges, and future perspectives in neonatal care. An integrative review / Método canguro: Beneficios, desafíos y perspectivas futuras en el cuidado neonatal. Una revisión integrativa / Cuidado canguru: benefícios, desafios e perspectivas futuras na assistência neonatal. Uma revisão integrativa

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.
