Introduction: This case report presents the intentional periodontal maintenance of two periodontal hopeless lower central incisors with a multidisciplinary approach and 20-year follow-up. Case presentation: A 36-year-old male, in 2001, was diagnosed with aggressive periodontitis, gingival swelling, bleeding, and mandibular central incisors with mobility and poor prognosis. Following periodontal therapy (phase I), root canal treatment, and occlusal adjustment, #31 and #41 were gently extracted to remove the granulation tissues, calculus, and infected cementum from the root surface. Then, tetracycline-HCl was applied for 5 minutes on the root surfaces. The teeth were repositioned into the sockets and splinted with a lingual bar. At 3 months, the bar was removed, and a free gingival autogenous graft was done to improve the local keratinized tissue width. Mobility scores, pocket depths, and clinical attachment levels were recorded, and radiographs were taken at 1, 5, and 20 years. The 5-year follow-up showed that the teeth were clinically and radiographically in function. There was a reduction in probing depth and a gain in clinical attachment and radiographic alveolar bone levels. After 20 years, #41 was stable, but #31 had external root resorption, leading to a new treatment plan (dental implants) and extraction. Conclusion: The clinical result of this case was satisfactory for 20 years. Intentional periodontal maintenance of the teeth may be an alternative treatment, even considering the high level of complexity.

Abstract Historically, it takes an average of 17 years for new treatments to move from clinical evidence to daily practice. Given the highly effective treatments now available to prevent or delay kidney disease onset and progression, this is far too long. Now is the time to narrow the gap between what we know and what we do. Clear guidelines exist for the prevention and management of common risk factors for kidney disease, such as hypertension and diabetes, but only a fraction of people with these conditions are diagnosed worldwide, and even fewer are treated to target. Similarly, the vast majority of people living with kidney disease are unaware of their condition, because it is often silent in the early stages. Even among patients who have been diagnosed, many do not receive appropriate treatment for kidney disease. Considering the serious consequences of kidney disease progression, kidney failure, or death, it is imperative that treatments are initiated early and appropriately. Opportunities to diagnose and treat kidney disease early must be maximized beginning at the primary care level. Many systematic barriers exist, ranging from the patient to the clinician to the health systems to societal factors. To preserve and improve kidney health for everyone everywhere, each of these barriers must be acknowledged so that sustainable solutions are developed and implemented without further delay.
Resumo Historicamente, são necessários, em média, 17 anos para que novos tratamentos passem da evidência clínica para a prática diária. Considerando os tratamentos altamente eficazes disponíveis atualmente para prevenir ou retardar o início e a progressão da doença renal, esse período é demasiadamente longo. Agora é o momento de reduzir a lacuna entre o que sabemos e aquilo que fazemos. Existem diretrizes claras para a prevenção e o manejo dos fatores de risco comuns para doenças renais, como hipertensão e diabetes, mas apenas uma fração das pessoas com essas condições é diagnosticada mundialmente, e um número ainda menor recebe tratamento adequado. Da mesma forma, a grande maioria das pessoas que sofrem de doença renal não têm conhecimento de sua condição, pois ela costuma ser silenciosa nos estágios iniciais. Mesmo entre pacientes que foram diagnosticados, muitos não recebem tratamento adequado para a doença renal. Levando em consideração as graves consequências da progressão da doença renal, insuficiência renal ou óbito, é imperativo que os tratamentos sejam iniciados precocemente e de maneira adequada. As oportunidades para diagnosticar e tratar precocemente a doença renal devem ser maximizadas, começando no nível da atenção primária. Existem muitas barreiras sistemáticas, que vão desde o paciente até o médico, passando pelos sistemas de saúde e por fatores sociais. Para preservar e melhorar a saúde renal para todos em qualquer lugar, cada uma dessas barreiras deve ser reconhecida para que soluções sustentáveis sejam desenvolvidas e implementadas sem mais demora.

ABSTRACT Introduction Ureteral stricture is often a consequence of urolithiasis or previous endourological procedures (1-3). Precisely delineating the stricture zone intraoperatively is crucial to minimize ureter shortening and target only the affected tissue (4, 5). Flexible ureteroscopy offers a significant advantage in this regard. Objective This video aims to demonstrate the step-by-step technique of flexible ureteroscopic guided laparoscopic ureteroplasty for treating ureteral stricture caused by urolithiasis and prior endourological interventions. Patient and Methods We present a case of a 36-year-old male with a history of urolithiasis and unsuccessful endourological treatments, including endoureterotomy and balloon dilation, diagnosed with re-stenosis of the proximal ureter of 1 cm through ureteroscopy and pyelography. He underwent a successful laparoscopic ureteroplasty. While the lead surgeon performed the laparoscopy, an assistant conducted the flexible ureteroscopy. Intraoperatively, using transillumination facilitated by the flexible ureteroscope, we can precisely identify the narrowed area, allowing for resection of only the damaged segment. Subsequently, we perform the end-to-end ureteroplasty, confirming its patency through the seamless passage of the ureteroscope. Upon completion, we employ a fat patch to safeguard the anastomosis. Results The patient was discharged on the third postoperative day. Double J stent was removed six weeks after surgery. Symptoms resolved. Renal function improved: eGFR 49 to 67 ml/min. Furthermore, improvement was observed in the DTPA scan, and a decrease in hydronephrosis was noted on the follow-up tomography. Conclusion Flexible ureteroscopy effectively identifies the stricture zone in laparoscopic ureteroplasty, enhancing surgical precision and outcomes. This approach is safe, effective, and reproducible, offering a valuable technique in the surgical treatment of ureteral strictures.

El síndrome de Herlyn-Werner Wünderlich, también llamado OHVIRA por sus siglas en inglés (obstructed hemivagina and ipsilateral renal anomaly), es una anomalía congénita mülleriana poco frecuente que se caracteriza por la asociación entre útero didelfo, hemivagina obstruida y agenesia renal ipsilateral. La presentación clínica más común es la masa abdominal secundaria a hematocolpos, dolor y dismenorrea. Se asocia a infertilidad, endometriosis, alteraciones menstruales y obstétricas. La ecografía es la técnica de elección para la evaluación inicial, mientras que la resonancia magnética sigue siendo el método más exacto para el diagnóstico. La septotomía vaginal es el tratamiento recomendado. Se describen 2 casos clínicos con el objetivo de destacar la importancia del diagnóstico temprano para evitar las posibles complicaciones futuras.
Herlyn-Werner-Wunderlich syndrome, also known as obstructed hemivagina and ipsilateral renal anomaly (OHVIRA), is a rare, congenital Müllerian duct anomaly characterized by the association of septate uterus, obstructed hemivagina, and ipsilateral renal agenesis. The most common clinical presentation is an abdominal mass secondary to hematocolpos, pain, and dysmenorrhea. It is associated with infertility, endometriosis, and menstrual and obstetric alterations. The ultrasound is the technique of choice for the initial assessment, while the magnetic resonance imaging remains the most accurate method for diagnosis. The resection of the vaginal septum is the recommended treatment. Here we describe 2 clinical cases to highlight the importance of an early diagnosis to prevent potential complications in the future.

Information on the knowledge and ways of using food and medicinal plants by traditional populations, family farmers and Brazilian native population in the Amazon is essential to guarantee the food sovereignty of these groups. This study was conducted using semi-structured interviews applied to local respondents. A total of 269 species of both non-conventional food plants and medicinal plants were identified, distributed in 83 botanical families and 198 genera. The Arecaceae and Lamiaceae families had the highest species richness (11 and 7, respectively). The Shannon-Wiener (H') and Pielou (J') diversity indices were considered high (5.02 and 0.9, respectively) when compared to other ethnobotanical works. In the environment in which these families are found, these species become the only food and medicinal resources available.

ABSTRACT Background: Success rates in endourological procedures, notably percutaneous nephrolithotomy (PCNL) and ureteroscopy (URS), have demonstrated suboptimal outcomes, leading to more reinterventions and radiation exposure. Recently, the use of intraoperative computed tomography (ICT) scans has been hypothesized as a promising solution for improving outcomes in endourology procedures. With this considered, we conducted a comprehensive systematic review and meta-analysis encompassing all available studies that evaluate the impact of the use of intraoperative CT scans on surgical outcomes compared to conventional fluoroscopic-guided procedures. Methods: This systematic review was conducted in accordance with PRISMA guidelines. Multiple databases were systematically searched up to December of 2023. This study aimed to directly compare the use of an ICT scan with the standard non-ICT-guided procedure. The primary endpoint of interest was success rate, and the secondary endpoints were complications and reintervention rates, while radiation exposure was also evaluated. Data extraction and quality assessment were performed following Cochrane recommendations. Data was presented as an Odds ratio with 95%CI across trials and a random-effects model was selected for pooling of data. Results: A comprehensive search yielded 533 studies, resulting in the selection of 3 cohorts including 327 patients (103 ICT vs 224 in non-ICT). Primary outcome was significantly higher in the experimental group versus the control group (84.5% vs 41.4% respectively, 307 patients; 95% CI [3.61, 12.72]; p<0.00001; I2=0). Reintervention rates also decreased from 32.6% in the control to 12.6% in the ICT group (OR 0.34; 95%CI [0.12,0.94]; p =0.04; I2= 48%), whereas complication rates did not exhibit significant differences. Radiation exposure was also significantly reduced in two of the included studies. Conclusion: This meta-analysis highlights a favorable outcome with intraoperative CT scan use in PCNL procedures, showing a considerable increase in SFR when compared to standard fluoroscopy and nephroscopy. Despite limited studies, our synthesis underscores the potential of ICT scans to significantly reduce residual stones and their consequences for endourology patients, as reinterventions and follow-up ionizing radiation studies.

ABSTRACT Purpose: To create a nomogram to predict the absence of clinically significant prostate cancer (CSPCa) in males with non-suspicion multiparametric magnetic resonance imaging (mpMRI) undergoing prostate biopsy (PBx). Materials and Methods: We identified consecutive patients who underwent 3T mpMRI followed by PBx for suspicion of PCa or surveillance follow-up. All patients had Prostate Imaging Reporting and Data System score 1-2 (negative mpMRI). CSPCa was defined as Grade Group ≥2. Multivariate logistic regression analysis was performed via backward elimination. Discrimination was evaluated with area under the receiver operating characteristic (AUROC). Internal validation with 1,000x bootstrapping for estimating the optimism corrected AUROC. Results: Total 327 patients met inclusion criteria. The median (IQR) age and PSA density (PSAD) were 64 years (58-70) and 0.10 ng/mL2 (0.07-0.15), respectively. Biopsy history was as follows: 117 (36%) males were PBx-naive, 130 (40%) had previous negative PBx and 80 (24%) had previous positive PBx. The majority were White (65%); 6% of males self-reported Black. Overall, 44 (13%) patients were diagnosed with CSPCa on PBx. Black race, history of previous negative PBx and PSAD ≥0.15ng/mL2 were independent predictors for CSPCa on PBx and were included in the nomogram. The AUROC of the nomogram was 0.78 and the optimism corrected AUROC was 0.75. Conclusions: Our nomogram facilitates evaluating individual probability of CSPCa on PBx in males with PIRADS 1-2 mpMRI and may be used to identify those in whom PBx may be safely avoided. Black males have increased risk of CSPCa on PBx, even in the setting of PIRADS 1-2 mpMRI

Abstract Objective: To build a model based on cardiometabolic indicators that allow the identification of overweight adolescents at higher risk of subclinical atherosclerotic disease (SAD). Methods: Cross-sectional study involving 161 adolescents with a body mass index ≥ + 1 z-Score, aged 10 to 19 years. Carotid intima-media complex thickness (IMT) was evaluated using ultrasound to assess subclinical atherosclerotic disease. Cardiometabolic indicators evaluated included nutritional status, central adiposity, blood pressure, lipidic profile, glycemic profile, as well as age and sex. Data was presented using measures of central tendency and dispersion, as well as absolute and relative frequency. The relationship between IMT measurement (outcome variable) and other variables (independent variables) was assessed using Pearson or Spearman correlation, followed by multiple regression modeling with Gamma distribution to analyze predictors of IMT. Statistical analysis was performed using SPSS and R software, considering a significance level of 5 %. Results: It was observed that 23.7 % had Carotid thickening, and the prevalence of abnormal fasting glucose was the lowest. Age and fasting glucose were identified as predictors of IMT increase, with IMT decreasing with age by approximately 1 % per year and increasing with glucose by around 0.24 % per mg/dL. Conclusion: The adolescent at higher risk is younger with higher fasting glycemia levels.

Objetivo: Analizar la percepción de la imagen corporal y su impacto en la función sexual orgásmica en mujeres estudiantes de la educación superior de Chillán, 2021. Métodos: Estudio cuantitativo, analítico, de corte transversal. Se evaluaron cuatro variables: datos demográficos, imagen corporal, orgasmo y función sexual. Se utilizó un Google Formulario a mujeres estudiantes entre 18 y 44 años de edad, de la educación superior en la ciudad de Chillán. Posterior a ello, los datos obtenidos se recopilaron y tabularon en el programa estadísticos SPSS 23. Resultados: Las dimensiones del índice de función sexual femenino alteradas con mayor frecuencia fueron: satisfacción (80,6 %), excitación (73,8 %) y orgasmo (51,5 %). El 99,0 % de las encuestadas presentaron disfunción sexual. Con respecto a la relación entre la dimensión de excitación y la pobre imagen corporal producida por el propio cuerpo (p = 0,019 r = -0,223) presentó correlación estadísticamente significativa, no así entre los puntajes totales de ambos instrumentos (p = 0,34; r = 0,09). Finalmente, las correlaciones entre la dimensión de dolor al momento de tener relaciones sexuales y la autodesvalorización por la apariencia física correlacionaron positivamente (p = 0,049; r = 0,196). Conclusión: Se observó alterado el orgasmo por la percepción de cómo se sienten con su propio cuerpo las encuestadas, lo que crearía una imagen corporal negativa llevando a una insatisfacción corporal(AU)
Objective: Analyze the perception of body image and its impact on orgasmic sexual function in female higher education students in Chillán, 2021. Methods: Quantitative, analytical, cross-sectional study. Four variables were evaluated: demographic data, body image, orgasm and sexual function. A Google Form was used for female students between 18 and 44 years of age, from higher education in the city of Chillán. Subsequently, the data obtained were compiled and tabulated in the statistical program SPSS 23. Results: The most frequently altered dimensions of the female sexual function index were: satisfaction (80.6%), arousal (73.8%), and orgasm (51.5%). 99.0% of the respondents had sexual dysfunction. Regarding the relationship between the arousal dimension and the poor body image produced by one's own body (p = 0.019; r = -0.223), there was a statistically significant correlation, but not between the total scores of both instruments (p = 0.34; r = 0.09). Finally, the correlations between the dimension of pain at the time of sexual intercourse and self-depreciation due to physical appearance were positively correlated (p = 0.049; r = 0.196). Conclusion: The orgasm was observed to be altered by the perception of how the respondents felt about their own body, which would create a negative body image leading to body dissatisfaction(AU)

Obesity is a global Non-Communicable Chronic Disease (NCD) associated with various comorbidities and a high mortality rate. This scenario has increasingly affected the female population, leading to a rise in prevalence and related health issues. Therefore, the present study aimed to assess the health-related quality of life of women with overweight or obesity and symptoms of COVID-19 using a multi-professional intervention model. This research was conducted as a parallel group and repeated measures pragmatic trial, in which 28 participants aged between 25 and 65 were allocated into two groups: experimental (intervention group) and control (non-intervention participants). The Body Mass Index (BMI) was (30.5 ± 5.45 kg/m²) in the Experimental Group, and the Control Group was (31 ± 8.2 kg/m2). The 12-Item Health Survey (SF-12) questionnaire was applied to assess the quality of life in the physical and mental domains of COVID-19 survivors with different symptom severities (mild, moderate, severe) compared to the control group. At the end of the program, 28 participants finished the study (15 from the experimental group and 13 from the control group). The results indicated a significant improvement in the mental health domain only in the experimental group after the intervention period (p 0.05). Considering these findings, multi-professional actions emerge as a crucial component for enhancing the quality of life, particularly within mental health, during the 16-week intervention period.
La obesidad es una Enfermedad Crónica No Transmisible (ECNT) global asociada a diversas comorbilidades y una alta tasa de mortalidad. Este escenario ha afectado cada vez más a la población femenina, lo que ha llevado a un aumento en la prevalencia y problemas de salud relacionados. El presente estudio tiene como objetivo evaluar la calidad de vida relacionada con la salud de mujeres con sobrepeso u obesidad y síntomas de COVID-19 mediante un modelo de intervención multiprofesional. Esta investigación se llevó a cabo como un ensayo pragmático de grupos paralelos y medidas repetidas, en el que 48 participantes con edades comprendidas entre 25 y 65 años fueron alocadas en dos grupos: experimental (participantes de la intervención) y control (participantes de la no intervención). En el grupo experimental el Índice de Masa Corporal (IMC) fue de (30,5 ± 5,45 kg/m²). En el grupo control, el IMC fue (31 ± 8,2 kg/m²). Se utilizó el cuestionario de 12-Item Health Survey (SF-12) para evaluar la calidad de vida en los dominios físico y mental de las sobrevivientes de COVID-19 con diferentes grados de gravedad de síntomas (leves, moderados, graves) en comparación con el grupo de control (participantes que no recibieron intervenciones). Al final del programa, 28 participantes terminado el estudio (15 participantes de la intervención y 13 sin intervención). Los resultados indicaron una mejora significativa en el dominio de la salud mental solo en el grupo experimental después del período de intervención (p 0.05). A la luz de estos hallazgos, la rehabilitación multiprofesional emerge como un componente crucial para mejorar la calidad de vida, especialmente en el ámbito de la salud mental durante el período de intervención de 16 semanas.

SUMMARY: Morphologically the Pterion marks the location of the four cranial bones, viz. frontal bone, sphenoid angle of the parietal bone, squamous part of the temporal bone and the greater wing of the sphenoid bone. Population-specific differences exists in the position and union of the Pterion. The Pterion is also an important neurosurgical landmark for surgical procedures, viz. Pterional/lateral approach, as it provides wide access to the base of the skull. This study aimed to determine the position and incidence of the various sutural patterns of the Pterion in a South African population of KwaZulu-Natal. This retrospective study was conducted bilaterally on 36 dry human skulls (11 females and 25 males) obtained from the Department of Clinical Anatomy at University of KwaZulu-Natal. Ethical clearance obtained from the Biomedical Research Ethics Committee. The morphometric parameters of the Pterion were measured using a digital Vernier caliper, while the morphological characteristics were examined using Murphy's classification scheme to determine (if any) laterality or sex differences exists. The mean distance of the Centre of the pterion from midpoint of zygoma was 44.4+/-4.1 mm in males and 45.1+/-4.6 mm in females. While the distance from frontozygomatic suture was 32.7+/-4.7 mm and 32.6+/-4.8 mm in males and females, respectively. Sphenoparietal type of pterion was most prevalent at 55.6 %, followed by the frontotemporal, stellate and epipteric type with an incidence of 27.8 %; 11.1 % and 5.6 %, respectively. No statistically significant difference for sex or laterality were documented in this study. The present study concluded that the sphenoparietal type of sutural pattern was most prevalent with an incidence of 55.6 %. While the epipteric type was the least prevalent. The comprehensive data about the position of the Pterion is important to neurosurgeons, forensics scientists and anthropologists.
Morfológicamente, el pterion marca la ubicación de los cuatro huesos craneales: hueso frontal, ángulo esfenoidal del hueso parietal, parte escamosa del hueso temporal y el ala mayor del hueso esfenoides. Existen diferencias específicas de la población en la posición y unión del pterion. El pterion es también un hito neuroquirúrgico importante para los procedimientos quirúrgicos en el bordaje pterional/lateral, ya que proporciona un amplio acceso a la base del cráneo. Esta investigación tuvo como objetivo determinar la posición y la incidencia de los diversos patrones suturales del pterion en una población sudafricana de KwaZulu-Natal. Este estudio retrospectivo se realizó bilateralmente en 36 cráneos humanos secos (11 mujeres y 25 hombres) obtenidos del Departamento de Anatomía Clínica de la Universidad de KwaZulu-Natal. ALa autorización ética fue otorgada porel Comité Ético de Investigación Biomédica. Los parámetros morfométricos del pterion se midieron usando un calibrador Vernier digital, mientras que las características morfológicas se examinaron usando el esquema de clasificación de Murphy para determinar, si existe alguna lateralidad o diferencias sexuales. La distancia media del centro del pterion desde el punto medio del cigoma fue de 44,4+/- 4,1 mm en hombres y de 45,1+/-4,6 mm en mujeres. Mientras que la distancia desde la sutura frontocigomática fue de 32,7+/-4,7 mm y 32,6+/-4,8 mm en hombres y mujeres, respectivamente. El tipo de pterion esfenoparietal fue el más prevalente con un 55,6 %, seguido del tipo frontotemporal, estrellado y epiptérico con una incidencia del 27,8 %; 11,1 % y 5,6 %, respectivamente. En el estudio no se documentaron diferencias estadísticamente significativas para el sexo o la lateralidad. Concluimos que el tipo de patrón de sutura esfenoparietal fue el más prevalente con una incidencia del 55,6 %. Mientras que el tipo epiptérico fue el menos prevalente. Los datos completos sobre la posición del pterion son importantes para los neurocirujanos, los científicos forenses y los antropólogos.

El 25% de los pacientes con Enfermedades Inflamatorias Intestinales (EII) se diagnostican antes de los 20 años. En la mayor parte de los centros del país se lleva a cabo la "transferencia" del paciente desde un centro de atención pediátrico a uno de adultos. La "transición" es un criterio de calidad con beneficios en el control de la EII reduciendo el número de recaídas, de hospitalizaciones y de cirugías. Por tal motivo hemos desarrollado un Programa Interdisciplinario de Transición entre dos hospitales de referencia nacional e internacional en EII. Materiales y métodos: Entre 1/2021 y 12/ 2022 se incorporaron 24 pacientes que ingresaron en 3 fases: Fase 1 Pacientes entre 14 y 16 años asistidos en el Hospital Garrahan (HG) con un abordaje interdisciplinario. Fase 2. A partir de los 17 años se realizaron 2 (dos) encuentros en el HG en conjunto con gastroenterólogos de adultos evaluando adherencia y autonomía y la Fase 3 llevada a cabo en el Hospital B. Udaondo (HBU) sólo con el equipo de adultos luego de 6 meses de realizada la transferencia evaluando adherencia al tratamiento, consultas a emergencias, internación y/o cirugías Resultados: Al inicio del Programa el 66% de los pacientes presentaban una actividad moderada a severa vs el 8% al finalizar la fase 3. Luego de la transferencia el 12,5% necesito ingreso a guardia e internación y un 8% tratamiento quirúrgico. El 83% de los pacientes continúan en seguimiento luego de 6 meses de haber sido transferidos (AU)
Twenty-five percent of patients with inflammatory bowel diseases (IBD) are diagnosed before the age of 20 years. In most centers in the country, the "transfer" of the patient from a pediatric to an adult care center is done. However, "transition" is a quality criterion with benefits in the control of IBD by reducing the number of relapses, hospitalizations, and surgeries. For this reason, we developed an Interdisciplinary Transition Program between two national and international reference hospitals in IBD. Materials and Methods: Between January 2021 and December 2022, we incorporated 24 patients into a three-phase program. Phase 1 involved patients between 14 and 16 years of age seen at Garrahan Hospital (HG) with an interdisciplinary approach. Phase 2 began from 17 years of age, with two meetings held at HG involving adult gastroenterologists to evaluate adherence and autonomy. Phase 3 was conducted at Hospital B. Udaondo (HBU) only with the adult team, six months after the transfer, evaluating adherence to treatment, emergency consultations, hospitalizations, and/or surgeries. Results: At the beginning of the program, 66% of the patients presented with moderate to severe disease activity, compared to 8% at the end of Phase 3. After the transfer, 12.5% of the patients required emergency department visits and hospitalization, and 8% required surgical treatment. Eighty-three percent of the patients continue in the program and are still being followed up six months after the transfer (AU)

Cada vez más pacientes trasplantados hepáticos durante la edad pediátrica alcanzan la adultez debido al aumento en las tasas de sobrevida a largo plazo, por lo que requieren continuar su atención en un centro de adultos. Este pasaje entre centros se asocia con peores resultados clínicos y mayor mala adherencia, debido al momento de vulnerabilidad que representa este momento en la atención médica y por el mismo momento vital atravesado por el paciente adolescente. La mayoría de los centros de trasplantes establecieron programas de transición para mejorar estos resultados. Para que estos programas sean efectivos, deben conocerse las barreras y los facilitadores de adherencia tanto en el paciente como en su entorno. El objetivo de este trabajo es reconocer estos factores de riesgo y su relación con mala adherencia y resultados clínicos, y realizar un seguimiento a corto plazo de los pacientes transferidos a un centro de atención de adultos. Para esto, se realizó una encuesta pre y post derivación a una cohorte de pacientes adolescentes del Hospital Garrahan. Para medir mala adherencia se utilizaron métodos objetivos y subjetivos, cada uno de los cuales correlacionó con distintos factores de riesgo, como presencia de violencia, consumo de sustancias y déficit educativo. Como conclusión, medir la mala adherencia es complejo debido a que su origen es multifactorial. Al parecer, combinar cuestionarios validados con entrevistas no estructuradas es la estrategia más efectiva para detectar mala adherencia en la consulta médica. Luego, las variables psicosociales están cobrando cada vez más relevancia y deben ser consideradas en los programas de transición de los servicios de trasplante si se quiere lograr un seguimiento a largo plazo exitoso (AU)
An increasing number of pediatric liver transplant patients reach adulthood due to the increase in long-term survival rates, and therefore require continued care in an adult center. This transition between centers is associated with worse clinical outcomes and poorer adherence, due to the vulnerability that this moment in medical care represents and the same vital moment that the adolescent patient goes through. Most transplant centers have established Transition Programs to improve these outcomes. For these programs to be effective, the barriers and facilitators of adherence in both the patient and their environment should be known. The aim of this study was to identify these risk factors and their relationship with poor adherence and clinical outcomes, and to perform a short-term follow-up of patients transferred to an adult care center. For this purpose, a pre- and post-referral survey was conducted on a cohort of adolescent patients from the Garrahan Hospital. Objective and subjective methods were used to measure poor adherence, each of which correlated with different risk factors, such as the presence of violence, substance use, and educational deficits. In conclusion, measuring poor adherence is complex because its origin is multifactorial. Combining validated questionnaires with unstructured interviews seems to be the most effective strategy for detecting poor adherence in the medical consultation. Therefore, psychosocial variables are becoming increasingly relevant and should be considered in the Transition Programs of transplantation services if a successful longterm follow-up is to be achieved (AU)

Abstract Introduction : Chia and flax seeds are rich in alpha-linolenic acid (ALA), which is bioconverted into the active derivatives eicosapentaenoic (EPA) and doco sahexaenoic (DHA) having multiple beneficial effects. However, there is limited knowledge about the anti-inflammatory effects of chia and flax integral flours diets rich in ALA. Objective : The study aimed to evaluate the anti-inflammatory effect of dietary supplementation with integral chia and flax flours in a murine model of LPS-induced systemic inflammation. Methods : Balb/c mice were distributed into three groups: diet A (control), diet B (supplemented with inte gral chia flour), and diet C (supplemented with integral flax flour). Nutritional, hematological, and biochemical determinations were performed. ALA, EPA, and DHA were assessed by GC-MS in the liver, brain, cardiac and skeletal muscles. NF-kB immunoassays were per formed in kidney, liver, and peritoneal macrophages, respectively. The phagocytic capacity was determined in peritoneal macrophages and the expression of the pro- and anti-inflammatory cytokines was assessed by RT-qPCR in the kidney, liver, and spleen. Results : Diets B and C exhibited optimal nutritional adequacy and caused increased levels of ALA, EPA, and DHA in critical tissues compared to the control. The phagocytic capacity of murine peritoneal macrophages (p< 0.01) and IL-10 transcription increased, whereas the expression of NF-κB, IL-1β, IL-6, and TNF-α decreased in animals fed both experimental diets. Conclusions : This work contributes to the current knowledge of the anti-inflammatory effects of chia and flax integral flours rich in ALA and reinforces the health advantages of their consumption.
Resumen Introducción : Las semillas de chía y lino son ricas en ácido alfa-linolénico (ALA), sus derivados activos eico sapentaenoico (EPA) y docosahexaenoico (DHA) ejercen probados efectos beneficiosos. Existe un conocimiento limitado sobre los efectos protectores de ambas semillas bajo la forma de harinas integrales, siendo de particular interés el efecto antiinflamatorio. Objetivo : El objetivo de este trabajo fue evaluar el efecto antiinflamatorio de la suplementación dietaria con harinas integrales de semillas de chía y lino en un modelo murino de inflamación sistémica inducido por LPS. Métodos : Ratones de la cepa Balb/c fueron distribui dos en tres grupos: dieta A (control), dieta B (suplemen tada con harina integral de chía) y dieta C (suplementa da con harina integral de lino). Se efecturaron determi naciones nutricionales, hematológicas y bioquímicas. El contenido de ALA, EPA y DHA en hígado, cerebro, corazón y músculo esquelético se determinó por cromatografía GC-MS. Se realizó la inmunodetección de NF-kB en macrófagos peritoneales, riñón e hígado. Se determinó la capacidad fagocítica de macrófagos peritoneales y se evaluó la expresión de citoquinas pro y antiinflamatorias por RT-qPCR en riñón, hígado y bazo. Resultados : Las dietas B y C mostraron una adecua ción nutricional óptima y generaron niveles elevados de ALA, EPA y DHA en tejidos críticos. La capacidad fagocítica de los macrófagos peritoneales (p< 0.01) y la transcripción de IL-10 aumentó, mientras que la expre sión de NF-κB, IL-1β, IL-6 y TNF-α disminuyó en animales de los grupos B y C. Conclusiones : Este trabajo contribuye al conocimien to actual de los efectos antiinflamatorios de ambas hari nas integrales y refuerza los beneficios de su consumo.

Abstract Introduction : Although therapeutic advances have improved results of cutaneous melanoma (CM), senti nel node-positive patients still have substantial risk to develop recurrent disease. We aim to investigate prog nostic indicators associated with disease recurrence in positive-sentinel lymph node biopsy (SLNB) patients in a Latin-American population. Methods : Retrospective analysis of CM patients and positive-SLNB (2010-2020). Patients were divided into two groups: Group A (completion lymph node dissection, CLND), Group B (active surveillance, AS). Association of demographics, tumor data and SLN features with recurrence-free (RFS), distant metastases-free (DMFS) and melanoma specific (MSS) survival was analyzed. Results : Of 205 patients, 45 had a positive SLNB; 27(60%) belonged to Group A and 18(40%) to Group B. With a median follow-up of 36 months, 16 patients (12 in Group A and 4 in Group B) developed recurrent dis ease and estimated 5-yr RFS at any site was 60% (CI95%, 0.39 - 0.77) (44.5% in CLND group vs. 22% in AS group; P = 0.20). Estimated 5-yr DMFS and MSS: 65% (CI 95%, 0.44 - 0.81) and 73% (CI 95%, 0.59 - 0.89) with no differ ences between groups (p = 0.41 and 0.37, respectively). Independent predictors of poorer MSS were extranodal extension (ENE) and MaxSize > 2 mm of melanoma deposit in SLN. Factors independently associated with DMFS: Breslow depth > 2 mm, ENE, number (≥ 2) of posi tive SN and CLND status. Conclusion : Primary tumor and SN features in mela noma provide important prognostic information that help optimize prognosis and clinical management. AS is now the preferred approach for most positive-SLNB CM patients.
Resumen Introducción : Si bien los avances terapéuticos han permitido mejorar los resultados del melanoma cutáneo (MC), los pacientes con ganglio centinela positivo (BGCP) aún tienen riesgo elevado de desarrollar recurrencia de la enfermedad. Nuestro objetivo fue investigar in dicadores pronósticos asociados a dicho evento en una población latinoamericana. Métodos : Análisis retrospectivo de pacientes con MC y BGCP entre 2010-2020. Los pacientes se dividieron en 2 grupos: Grupo A (linfadenectomía terapéutica) y Grupo B (Vigilancia activa, VA). Se analizaron datos demográficos, tumorales y características del GC junto con sobrevida-libre de recurrencia (SLR), libre de metástasis a distancia (SLMD) y específica de melanoma (SEM). Resultados : De 205 pacientes, 45 presentaron BGCP; 27 (60%) perteneció al Grupo A y 18 (40%) al Grupo B. Con una mediana de seguimiento de 36 meses, 16 pa cientes (12 en Grupo A y 4 en Grupo B) desarrollaron enfermedad recurrente con una SLR a 5 años de 60% (IC95%: 0.39-0.77) (44.5% en Grupo B vs. 22% en Grupo A; P = 0.20). Las SLMD y SEM estimadas a 5 años fueron de 65% (CI 95%, 0.44 - 0.81) y 73% (CI 95%, 0.59 - 0.89) sin diferencias entre ambos grupos (p = 0.41 y 0.37, respec tivamente). Los predictores independientes de peor SEM fueron: extensión extranodal (ENE) y MaxSize > 2mm de depósito tumoral en GC. Los factores asociados de forma independiente con SLMD fueron Breslow >2mm, ENE, número (≥ 2) de GC positivos y el status (positividad) de la linfadenectomía. Conclusión : Características del tumor primario y del GC brindan información importante que ayuda a optimi zar el pronóstico y manejo clínico de los pacientes con MC. La VA es actualmente el abordaje de elección para la mayoría de los pacientes con BGCP.
