RESUMO

INTRODUCTION: Membranous nephropathy (MN) is the most common cause of primary nephrotic syndrome in adults (20-30%). Light microscopy shows thickening of glomerular basement membrane with appearance of spikes. These histological findings are not evident in early forms, in which case the granular deposition pattern of IgG and/or C3 in the basement membrane by immunofluorescence (IF) constitutes the diagnostic tool that allows to differentiate it from minimal change disease (MCD). Complement system plays a key role in the pathophysiology of MN. C4d is a degradation product and a marker of the complement system activation. C4d labelling by immunohistochemical (HI) technique can help in the differential diagnosis between both glomerulopathies NM and MCD when the material for IF is insufficient and light microscopy is normal. Our objective was to explore the discrimination power of C4d to differentiate between MN and MCD in renal biopsy material. METHODS: Paraffin-embedded samples were recovered from renal biopsies with a diagnosis of MN and MCD performed between 1/1/2008 and 4/1/2019. IH staining was performed by immunoperoxidase technique using a rabbit anti-human C4d polyclonal antibody. RESULTS: In all cases with MN (n = 27, 15 males) with a median age of 63 (range: 18-87) years, C4d deposits were detected. In 21 cases with MCD (12 males) with a median age of 51 (range: 18-87) years, the C4d marking was negative in every samples. CONCLUSION: The results indicate that the marking of the renal biopsy with C4d is a useful tool for the differential diagnosis between NM and MCD.

Introducción: La nefropatía membranosa (NM) es la causa más frecuente de síndrome nefrótico primario en adultos (20-30%). En la microscopia óptica se observa engrosamiento de membrana basal glomerular con aparición de espigas. Estos hallazgos histológicos no son evidentes en formas tempranas, en cuyo caso el patrón de depósito granular de IgG y/o C3 en la membrana basal por inmunofluorescencia (IF) permite diferenciarla de enfermedad por cambios mínimos (ECM). El sistema del complemento juega un papel central en la fisiopatología de la NM. C4d es producto de degradación y un marcador de la activación del complemento. La marcación con C4d en muestras de biopsias renales, por técnica de inmunohistoquímica (IH) puede colaborar en el diagnóstico diferencial entre ambas glomerulopatías. Nuestro objetivo fue explorar el poder de discriminación del C4d para diferenciar NM de ECM en material de biopsias renales. Métodos: Se recuperaron muestras en parafina de biopsias renales con diagnóstico de NM y ECM realizados entre 1/1/2008 y 1/4/2019. Se realizaron tinciones de IH por técnica de inmunoperoxidasa con C4d usando un anticuerpo policlonal antihumano de conejo. Resultados: En todos los casos con NM (n = 27, 15 hombres) con mediana de edad de 63 (rango: 18-86) años se detectaron depósitos de C4d. En los 21 casos con ECM (12 hombres) con mediana de edad de 51 (rango: 18-87) años la marcación de C4d fue negativa. Conclusión: Los resultados indican que la marcación de la biopsia renal con C4d es una herramienta útil para el diagnóstico diferencial entre NM y ECM.

RESUMO

INTRODUCTION: Genetic associations with Alzheimer's disease (AD) age at onset (AAO) could reveal genetic variants with therapeutic applications. We present a large Colombian kindred with autosomal dominant AD (ADAD) as a unique opportunity to discover AAO genetic associations. METHODS: A genetic association study was conducted to examine ADAD AAO in 340 individuals with the PSEN1 E280A mutation via TOPMed array imputation. Replication was assessed in two ADAD cohorts, one sporadic early-onset AD study and four late-onset AD studies. RESULTS: 13 variants had p<1×10-7 or p<1×10-5 with replication including three independent loci with candidate associations with clusterin including near CLU. Other suggestive associations were identified in or near HS3ST1, HSPG2, ACE, LRP1B, TSPAN10, and TSPAN14. DISCUSSION: Variants with suggestive associations with AAO were associated with biological processes including clusterin, heparin sulfate, and amyloid processing. The detection of these effects in the presence of a strong mutation for ADAD reinforces their potentially impactful role.

RESUMO

BACKGROUND: In fewer than 1% of patients, AD is caused by autosomal dominant mutations in either the presenilin 1 (PSEN1), presenilin 2 (PSEN2), or amyloid precursor protein (APP) genes. The full extent of familial AD and frequency of these variants remains understudied in Latin American (LatAm) countries. Due to the rare nature of these variants, determining the pathogenicity of a novel variant in these genes can be challenging. Here, we use a systematic approach to assign the likelihood of pathogenicity in variants from densely affected families in Latin American populations. METHODS: Clinical data was collected from LatAm families at risk for DIAD. Symptomatic family members were identified and assessed by local clinicians and referred for genetic counseling and testing. To determine the likelihood of pathogenicity among variants of unknown significance from LatAm populations, we report pedigree information, frequency in control populations, in silico predictions, and cell-based models of amyloid-beta ratios. RESULTS: We identified five novel variants in the presenilin1 (PSEN1) gene from Brazilian and Mexican families. The mean age at onset in newly identified families was 43.5 years (range 36-54). PSEN1 p.Val103_Ser104delinsGly, p.Lys395Ile, p.Pro264Se, p.Ala275Thr, and p.Ile414Thr variants have not been reported in PubMed, ClinVar, and have not been reported in dominantly inherited AD (DIAD) families. We found that PSEN1 p.Val103_Ser104delinsGly, p.Lys395Ile, p.Pro264Se, and p.Ala275Thr produce Aß profiles consistent with known AD pathogenic mutations. PSEN1 p.Ile414Thr did not alter Aß in a manner consistent with a known pathogenic mutation. CONCLUSIONS: Our study provides further insights into the genetics of AD in LatAm. Based on our findings, including clinical presentation, imaging, genetic, segregations studies, and cell-based analysis, we propose that PSEN1 p.Val103_Ser104delinsGly, p.Lys395Ile, p.Pro264Se, and p.Ala275Thr are likely pathogenic variants resulting in DIAD, whereas PSEN1 p.Ile414Thr is likely a risk factor. This report is a step forward to improving the inclusion/engagement of LatAm families in research. Family discovery is of great relevance for the region, as new initiatives are underway to extend clinical trials and observational studies to families living with DIAD.

RESUMO

Resumen Introducción/objetivo: El acoso sexual es una de las violencias que más debe preocupar a la comunidad educativa, por ello, el objetivo de este estudio consiste en analizar los conocimientos, las percepciones y las actitudes de los y las estudiantes universitarios hacia el acoso sexual. Método: Desde un enfoque cualitativo se han realizado diez entrevistas individuales a estudiantes (seis alumnas y cuatro alumnos) y ocho grupos de discusión heterogéneos formados por 67 estudiantes. Todos pertenecientes a una universidad de carácter público situada en el noroeste de España. Resultados: El alumnado tiene pocos conocimientos sobre el acoso sexual y, además, no recibe formación que le otorgue las herramientas que le permitan identificarlo y combatirlo. Asimismo, la mayoría de los/as participantes expresa que el acoso sexual es habitual en el entorno académico, pero que está invisibilizado. A través de sus propias palabras se identifica que perciben actitudes permisivas hacia el acoso sexual por parte de los/as docentes y de la universidad, considerando que no hay una verdadera implicación para intervenir en las situaciones de acoso. Conclusiones: Es necesario que la universidad se comprometa a implementar estrategias de prevención e intervención, con el propósito de identificar, sancionar y erradicar todas y cada una de las formas de violencia, incluido el acoso sexual.

Abstract Introduction/objective: Sexual harassment is one of the types of violence that should most concern the educational community, consequently, the objective of this study is to analyze the knowledge, perceptions and attitudes of university students towards sexual harassment. Method: From a qualitative approach, ten individual interviews were carried out with students (six female students and four male students) and eight heterogeneous discussion groups made up of 67 students. All of them belong to a public university located in the northwest of Spain. Results: The students have little knowledge about sexual harassment and, in addition, they do not receive training that gives them the tools that allow them to identify and combat it. Likewise, most of the participants express that sexual harassment is common in the academic environment, but that it is invisible. Through their own words, it is identified that they perceive permissive attitudes towards sexual harassment on the part of teachers and the university, considering that there is no real implication to intervene in harassment situations. Conclusions: It is necessary for the university to commit to implement prevention and intervention strategies, in order to identify, punish and eradicate each and every one of the forms of violence, including sexual harassment.

RESUMEN Introducción: La insuficiencia renal aguda en pacientes internados en unidades de terapia intensiva es frecuente y se asocia con alta mortalidad. El objetivo del trabajo fue identificarfactores relacionados con mortalidad en pacientes internados en unidades de terapia intensiva con insuficiencia renal aguda que requirieron tratamiento sustitutivo de la función renal.Material y métodos:Se identificaron, en forma retrospectiva, 3.732pacientes internados en unidades de terapia intensiva. El 2,7% presentaron insuficiencia renal aguda con requerimiento de tratamiento sustitutivo de la función renal. Se excluyeron pacientes con antecedentes de enfermedad renal crónica con filtrado glomerular menor de 15 ml/m o en diálisis crónica. Resultados:Se analizaron 97 casos, 55% mujeres, mediana de edad 74 años (rango intercuartil: 68-78). Los motivos de insuficiencia renal aguda más frecuentes fueron sepsis (41,2%) y necrosis tubular aguda isquémica (36,1%). El 22,7% eran diabéticos. La mediana de APACHE II fue 23 (rango intercuartil: 19-28). El 75,3% requirió asistencia respiratoria mecánica y el 81,4%, inotrópicos. La mediana de tiempo de internación en unidades de terapia intensiva fue de 8 días (rango intercuartil: 4-11) y la mortalidad fue 58,76%.En el análisis individual, la mortalidad se asoció con asistencia respiratoria mecánica (p<0,0001), el uso de inotrópicos (p<0,0001) y el antecedente deenfermedad renal crónica (p=0.008), pero no se encontró asociación con sexo, edad, APACHE II, diabetes ni otros factores de riesgo cardiovascular. Modelo multivariable de factores asociados con mortalidad: asistencia respiratoria mecánica (Odds Ratio=14,16; p=0,003), inotrópicos (Odds Ratio=8,73; p=0,07) y enfermedad renal crónica (Odds Ratio=0,27; p=0,020).Conclusiones:Los pacientes con insuficiencia renal agudaque requirieron tratamiento sustitutivo de la función renal ingresados a unidades de terapia intensiva presentaron alta mortalidad. El requerimiento de asistencia respiratoria mecánica se asoció con mayor mortalidad, también el uso de inotrópicos, aunque no alcanzó significación estadística en el multivariable. El antecedente de enfermedad renal crónica se asoció con menor mortalidad.

ABSTRACT Introduction: Acute renal failure in patients admitted to intensive care units is common and is associated with high mortality. The aim of the study was to identify factors related to mortality in patients with acute renal failure, hospitalized in intensive care units, who required renal replacement therapy. Methods: We retrospectively identified 3,732 patients admitted to intensive care units; 2.7% had acute renal failure requiring replacement therapy for renal function. Patients with a history of chronic kidney disease with a glomerular filtration rate of less than 15 mL/m or on chronic dialysis were excluded. Results: 97 cases were analyzed, 55% women, median age: 74 years (interquartile range: 68-78). The most frequent reasons for acute renal failure were sepsis (41.2%) and ischemic acute tubular necrosis (36.1%); 22.7% were diabetic. The median APACHE II score was 23 (interquartile range: 19-28). 75.3% required mechanical ventilation and 81.4%, inotropic drugs. Median time of hospitalization in intensive care units was 8 days (interquartile range: 4-11) and the mortality rate was 58.76%. In the individual analysis, mortality was associated with mechanical ventilation (p<0.0001), the use of inotropic drugs (p<0.0001) and a history of chronic kidney disease (p=0.008), but no association was found with sex, age, APACHE II score, diabetes, or other cardiovascular risk factors. Multivariate model of factors associated with mortality: mechanical ventilation (Odds Ratio=14.16; p=0.003), inotropic drugs (Odds Ratio=8.73; p=0.07) and chronic kidney disease (Odds Ratio=0.27; p=0.020). Conclusions: Patients with acute renal failure who required renal replacement therapy and were admitted to intensive care units presented high mortality. The requirement for mechanical ventilation was associated with higher mortality, as was the use of inotropic drugs, although it did not reach statistical significance in the multivariate analysis. A history of chronic kidney disease was associated with lower mortality.

RESUMO

Resumen (analítico) El Sistema de Protección a la Infancia y a la Adolescencia español utiliza los mismos mecanismos con la población tutelada nacional que con la extranjera de origen latinoamericano. Con esta investigación se pretende conocer las dificultades específicas de la juventud procedente de América Latina, en edad de emancipación y que tiene expediente de protección, así como identificar estrategias eficaces para la actuación socioeducativa. Mediante metodología cualitativa, en el marco de la teoría fundamentada, se realizan con juventud tutelada seis seguimientos longitudinales y cuatro relatos de vida. Se concluye con dos grupos de discusión con figuras profesionales especializadas. Los resultados muestran déficits en el acompañamiento socioeducativo, especialmente producto del choque entre las metas del proyecto migratorio y la rigidez del sistema. Se constata la ausencia de redes sociales de apoyo para la emancipación.

Abstract (analytical) The Protection System for Children and Adolescents in Spain has the same mechanisms for the national population as it does for the foreign population of children and Young people who are originally from Latin American. This research aimed to determine the specific emancipation difficulties of youths from Latin America with a Child Protective Service record, as well as to identify effective strategies for socioeducational actions. Using a qualitative methodology within the grounded theory framework, six longitudinal monitoring studies and four life story narrations are conducted with protected young people. The study concluded with two discussion groups with specialized professional figures. The results reveal deficits in educational accompaniment, especially as a result of the collision between migratory project goals and the rigidity of the education system. The absence of social support networks to contribute to their emancipation is confirmed.

RESUMO

Pregnancy and lactation, especially when concurrent, create a rather metabolically demanding situation in dairy ruminants, but little is known about their effects on offspring phenotype and milk yield. Here, we evaluated the impact of pregnancy and lactation on the metabolic traits and productive performance of Lacaune dairy sheep and their offspring. Productive performance was measured in terms of milk yield, body weight (BW), body condition score (BCS), and size. Productivity was assessed during mid-pregnancy (75 ± 5 d) and late pregnancy (142 ± 4 d) and at 52 ± 5 d in the postpartum period. During pregnancy, high-yielding ewes had higher BW, BCS, plasma glucose, cholesterol, ß-OHB, and NEFA than low-yielding ewes, but lower levels of lactate and urea. High-yielding animals had lower BCS after lambing, but their lambs showed greater growth. Productivity during lactation was affected by ewe age and parity: Mature ewes (but not maiden sheep) whose BCS increased steeply during pregnancy yielded more milk in the subsequent lactation than those whose BCS did not increase. Lamb BW and size were positively associated with milk yield in the subsequent lactation. Mature ewes had higher yields than maiden sheep, and mature ewes with multiple pregnancies produced more milk than those with singleton pregnancies. Ewes with male singleton pregnancies also showed higher yield than those with female singletons. These results demonstrate that high-yielding dairy sheep, when appropriately fed and managed, can adequately cover the metabolic demands of pregnancy and high milk production (even when concurrent) without losing productivity.

RESUMO

Pregnancy and lactation are challenging states that affect maternal and lamb health. In Lacaune dairy sheep, we evaluated the impact of parity, pregnancy rank, and body condition on body weight and the condition of ewes and lambs in mid-pregnancy (75 ± 5 d), in late pregnancy (142 ± 4d), and postpartum (52 ± 5d pp). Maternal age was associated with initial decreases, followed by increases, in body weight and condition. After lambing, both mature and maiden ewes lost weight and body condition. Maternal indices of glucose, protein, and lipid metabolism were within physiological values during pregnancy, but postpartum values depended on maternal parity and pregnancy rank, with multiple-pregnant ewes showing a postpartum increase in glucose and maiden sheep a postpartum increase in plasma cholesterol concentration. Male lambs were heavier than female lambs at birth, and lambs born to mothers with higher body condition scores were heavier. Lambs born as singletons were heavier than those born in litters. Maternal age and pregnancy rank did not influence lamb metabolic indicators. Sex affected plasma concentrations of glucose, triglycerides, and cholesterol. Maternal metabolic indicators showed minimal effects on lamb phenotype. These results suggest that, when appropriately fed, dairy sheep can cover the metabolic demands of pregnancy and milk production, regardless of age and pregnancy rank.

RESUMO

ntroducción: La diabetes mellitus tipo 1 (DM1) es la enfermedad crónica más frecuente en la edad pediátrica. La educación del niño con DM1 es fundamental para un adecuado control de la enfermedad. Las lipohipertrofias son una de las complicaciones más frecuentes que se producen por el tratamiento con insulina. Estas son consideradas problemas de colaboración y, por lo tanto, es labor de la enfermera controlar su aparición e intervenir para minimizar sus consecuencias. Objetivo: Determinar las características de las lipohipertrofias en niños diagnosticados con diabetes mellitus tipo 1. Métodos: Estudio descriptivo transversal mediante muestreo por conveniencia. Se evaluó la presencia, localización y tamaño de las lipohipertrofias y la relación de la persona que administra la insulina con el régimen de tratamiento. Se estudiaron pacientes de edades comprendidas entre 2 y 18 años que tuviesen, al menos, 3 meses de tratamiento insulínico. Se calculó el tamaño de la muestra mediante estimación de la proporción. Resultados: La prevalencia de lipohipertrofias fue del 44,5 por ciento. Sin embargo, entre los niños estudiados que se encontraban en tratamiento con múltiples dosis de insulina, el porcentaje se elevó a 53,8 por ciento. Los análogos de acción rápida eran inyectados principalmente en abdomen y brazo, los de acción lenta en glúteo y muslo. Los lugares con más lipohipertrofias eran muslos (superando el 50 por ciento), seguido de brazos y abdomen. Conclusiones: Se detectaron diferencias significativas en la aparición de lipohipertrofias entre los niños que portan bomba de insulina y los que utilizan un régimen de múltiples dosis de insulina. Por lo tanto, se podría recomendar la utilización de bomba de insulina o de catéteres de infusión subcutánea (i-Port ®) para la disminución de estas(AU)

Introduction: Type 1 diabetes mellitus (T1DM) is the most common chronic disease in the pediatric age. In order to obtain a positive control of this illness, the T1DM child education is basic. Lipohypertrophies are one of the most frequent difficulties that appear as a consequence of the insulin treatment. When this happen, is nurse's responsibility to monitor the appearance of lipohypertrophies and to try to reduce their consequences. Objectives: Establish the prevalence of lipohypertrophy in children with T1DM performed at the Pediatric Endocrinology Unit of the Hospital Universitario La Paz. Methods: To analyze lipohypertrophy it has been performed a descriptive study. The method used for the sampling was for convenience. Appearance, location and size of lipohypertrophies were evaluated. This has been related with person who administers the insulin and the treatment regimen. Results: Lipohypertrophy prevalence in the sample represented a 44.5 percent, however, between patients which were in a treatment with multiple daily injections this was 53.8 percent. Quick action analogues were mainly injected in abdomen and arms, slow action analogues were aministered in buttocks and leg. Legs were the part of the body with the most lipohypertrophies concentration (exceeded 50 percent), follow by arms and abdomen. Conclusions: Meaningful differences are shown in the appearance of lipohypertrophies between children in treatment with continuous subcutaneous insulin infusion and those that use a multiple daily injections treatment. Therefore, we concluded considering the possibility to recommend the use of continuous subcutaneous insulin infusion or indwelling catheters (i-Port ®) in order to decrease lipohypertrophies(AU)

RESUMO

La violencia de pareja afecta a personas transexuales, transgénero e intersexuales y así se visibiliza en investigaciones a nivel nacional e internacional. En este estudio teórico se ha llevado a cabo una revisión sistemática de las investigaciones realizadas con estos colectivos. Se realiza una revisión exhaustiva de las principales bases de datos con el fin de identificar todos los estudios relativos a esta temática. Se obtiene un total de 28 investigaciones sobre violencia en parejas transexuales, transgénero e intersexuales. De las cuales se ha analizado el tipo de muestra, el método e instrumento utilizado, así como sus principales resultados. Los resultados ponen de relieve que la aproximación de estudio más frecuentemente utilizada es la de tipo cuantitativo, especialmente centrada en el colectivo transexual. En relación a la prevalencia se observa una gran variabilidad, con un rango del 18 al 80%, constituyendo un problema de salud pública. Las mujeres trans son las que sufren más significativamente esta violencia, siendo más frecuentemente el miembro normativo de la pareja quien la ejerce. El heterosexismo y la transfobia se han identificado como factores de riesgo. Finalmente se plantea la importancia de incorporar el abordaje de la violencia en relaciones de pareja donde al menos uno de los miembros es transexual, transgénero o intersexual en los programas de prevención de violencia de género.

Intimate partner violence affects transsexual, transgender and intersex individuals and has been approached by national and international research. This theoretical study has carried out a systematic review of research conducted with these groups. An exhaustive review of the main databases was performed to identify all the studies that focus on this subject. Overall, 28 studies were obtained on violence in transsexual, transgender and intersex couples. In each study, we analyzed the type of sample, method and instrument that were used, as well as the main results. The results highlight that the quantitative approach is the most common one, focusing especially on the transsexual community. Concerning prevalence, we observed a great variability, ranging from 18 to 80%, constituting a public health problem. Trans women are the ones who most suffer this type of violence, and the "gender-normative" member of the couple is most frequently the aggressor. Heterosexism and transphobia were identified as risk factors. Finally, the importance of including intimate partner violence in relationships in which at least one of the members is transsexual, transgender or intersex in gender violence prevention programs is highlighted.

RESUMO

Introducción: el síndrome de Hakim Adams, o hidrocefalia normotensiva, es un cuadro progresivo que se caracteriza por presentar alteración de la marcha, trastornos esfinterianos y demencia, y que afecta principalmente a pacientes añosos. Si bien existen publicaciones sobre los resultados del tratamiento quirúrgico, estos trabajos suelen evaluar la mejoría sintomática pero no la calidad de vida de los pacientes. Objetivo: Conocer el impacto del tratamiento en pacientes con síndrome de Hakim Adams tratados con derivación de LCR. Material y Métodos: Realizamos un estudio retrospectivo de una serie de 8 pacientes. Se realizó una encuesta para la evaluación preoperatoria y postoperatoria; con un tiempo transcurrido no menor a 6 meses luego del procedimiento. Se utilizó la escala de Barthel para la funcionalidad, y una escala numérica simple para la calidad de vida. Resultados: Previo a la cirugía, 7 casos presentaban alteraciones de la marcha y/o problemas para deambular; 6 casos alteraciones esfinterianas; y 5 casos algún tipo de alteración neurocognitiva. Luego de la cirugía, todos los pacientes refirieron un cambio significativo en la calidad de vida; y también en la funcionalidad, logrando 6 pacientes una independencia absoluta. Conclusión: Aunque nuestra comunicación tiene las debilidades de una serie pequeña de casos analizados en forma retrospectiva, los resultados son concluyentes en cuanto a mejora en la calidad de vida y funcionalidad en el postoperatorio. Creemos que esta modalidad de evaluación puede ayudar a los pacientes y/o familiares de pacientes en el proceso de toma decisiones del tratamiento quirúrgico.

Introduction: the Hakim Adams’ syndrome is a chronic hydrocephalus of the elderly with normal or low CSF pressure that clinically have gait disturbances, urinary incontinence and dementia. Although there are some publications about the surgical results in terms of the relief of symptoms, they don’t usually evaluate the patients’ quality of life. Material and Methods: We are reporting a retrospective study of a series of 8 patients with diagnosis of Hakim Adams’ syndrome that was performed to assess the influence of CSF shunting on their quality of life. A survey was performed to record the preoperative status, with at least 6-months after surgery. Functional results were evaluated with Barthel’s scale; and the quality of life with a simple numeric scale. Results: Before surgery, 7 cases had gait disturbances; 6 cases had urinary incontinence; and 5 cases had neurocognitive impairment. Postoperatively, all patients reported a significative change in their quality of life, and also in the functional scale; 6 cases obtained total independence. Conclusion: Although our communication has the weakness of the small number of cases evaluated in a retrospective manner, the results are conclusive in terms of functionality improvement and quality of life. This kind of assessment may help to our patients and/or patients’ family in the decision making process of shunting procedures.

RESUMO

Short-finned squid Illex argentinus (Omastrephidae) is an economically important species which supports a long-term and intensive commercial fishery in the South-West Atlantic Ocean. In this study, the genetic variability of allozymes (40 loci) and mitochondrial regions, COI (556 bp) and 16S rDNA (439 bp), were addressed in the two most important species' spawning stocks, the Summer Spawning Stock (SSS) and the South Patagonic Stock (SPS). Five out of 20 polymorphic allozyme loci were polymorphic at 95% criterion and heterozygosity levels were low. The concatenated analysis of mitochondrial molecular markers revealed high to low values of haplotype and nucleotide diversity, respectively. Nuclear and mitochondrial data revealed no significant genetic differences between these two spawning stocks. Our results and the biological characteristics of I. argentinus deal with a no simple genetic structure of populations described as spatial and temporal chaotic patchiness. SSS and SPS spawning stocks of I. argentinus could not be elevated to the status of genetic stocks.

RESUMO

Se presenta un programa de educación sexual llevado a cabo con padres y madres en un centro de educación secundaria. Éste fue desarrollado de forma paralela al programa realizado con sus hijos y/o hijas adolescentes. Los principales resultados derivados de su evaluación, de carácter procesual y formativo, evidencian un incremento del nivel de satisfacción corporal, autoconcepto y autoestima, así como de sus conocimientos sobre nutrición y órganos sexuales. Se constata también un incremento de actitudes igualitarias hacia ambos sexos y de actitudes erotofílicas hacia la sexualidad. El programa fue valorado positivamente por quienes participaron. Se destacó la importancia de implementar experiencias que, como ésta, supongan una alternativa a la sobredimensionada educación de la inteligencia racional, en pro de un desarrollo integral de la personalidad de los y las adolescentes.

This paper outlines a sex education programme carried out with the parents of secondary school students taking part in a similar programme simultaneously. Results reveal an increase in participants' overall level of satisfaction with their bodies, self-concept, and self-esteem, as well as an increased knowledge about sexual organs and nutrition. There was also a rise in the number of egalitarian attitudes toward the two sexes and positive attitudes toward sexuality. Overall, participants' evaluations of the programme were positive. They pointed out the importance of implementing programmes such as these, which offer an alternative to the traditional model of education centered mainly on rational intelligence, and which encourage more holistic development of personality among teenagers.
