Risk profiles and penetrance estimations in multiple endocrine neoplasia type 2A caused by germline RET mutations located in exon 10

Multiple endocrine neoplasia type 2 is characterized by germline mutations in RET. For exon 10, comprehensive molecular and corresponding phenotypic data are scarce. The International RET Exon 10 Consortium, comprising 27 centers from 15 countries, analyzed patients with RET exon 10 mutations for clinical-risk profiles. Presentation, age-dependent penetrance, and stage at presentation of medullary thyroid carcinoma (MTC), pheochromocytoma, and hyperparathyroidism were studied. A total of 340 subjects from 103 families, age 4-86, were registered. There were 21 distinct single nucleotide germline mutations located in codons 609 (45 subjects), 611 (50), 618 (94), and 620 (151). MTC was present in 263 registrants, pheochromocytoma in 54, and hyperparathyroidism in 8 subjects. Of the patients with MTC, 53% were detected when asymptomatic, and among those with pheochromocytoma, 54%. Penetrance for MTC was 4% by age 10, 25% by 25, and 80% by 50. Codon-associated penetrance by age 50 ranged from 60% (codon 611) to 86% (620). More advanced stage and increasing risk of metastases correlated with mutation in codon position (609?620) near the juxtamembrane domain. Our data provide rigorous bases for timing of premorbid diagnosis and personalized treatment/prophylactic procedure decisions depending on specific RET exon 10 codons affected.

Promises of cyclotron-produced 44Sc as a diagnostic match for trivalent β--emitters: in vitro and in vivo study of a 44Sc-DOTA-folate conjugate

In recent years, implementation of 68Ga-radiometalated peptides for PET imaging of cancer has attracted the attention of clinicians. Herein, we propose the use of 44Sc (half-life = 3.97 h, average β+ energy [Eβ+av] = 632 keV) as a valuable alternative to 68Ga (half-life = 68 min, Eβ+av = 830 keV) for imaging and dosimetry before 177Lu-based radionuclide therapy. The aim of the study was the preclinical evaluation of a folate conjugate labeled with cyclotron-produced 44Sc and its in vitro and in vivo comparison with the 177Lu-labeled pendant. Methods: 44Sc was produced via the 44Ca(p,n)44Sc nuclear reaction at a cyclotron (17.6 ± 1.8 MeV, 50 μA, 30 min) using an enriched 44Ca target (10 mg 44CaCO3, 97.00%). Separation from the target material was performed by a semiautomated process using extraction chromatography and cation exchange chromatography. Radiolabeling of a DOTA-folate conjugate (cm09) was performed at 95°C within 10 min. The stability of 44Sc-cm09 was tested in human plasma. 44Sc-cm09 was investigated in vitro using folate receptor–positive KB tumor cells and in vivo by PET/CT imaging of tumor-bearing mice Results: Under the given irradiation conditions, 44Sc was obtained in a maximum yield of 350 MBq at high radionuclide purity (>99%). Semiautomated isolation of 44Sc from 44Ca targets allowed formulation of up to 300 MBq of 44Sc in a volume of 200–400 μL of ammonium acetate/HCl solution (1 M, pH 3.5–4.0) within 10 min. Radiolabeling of cm09 was achieved with a radiochemical yield of greater than 96% at a specific activity of 5.2 MBq/nmol. In vitro, 44Sc-cm09 was stable in human plasma over the whole time of investigation and showed folate receptor–specific binding to KB tumor cells. PET/CT images of mice injected with 44Sc-cm09 allowed excellent visualization of tumor xenografts. Comparison of cm09 labeled with 44Sc and 177Lu revealed almost identical pharmacokinetics. Conclusion: This study presents a high-yield production and efficient separation method of 44Sc at a quality suitable for radiolabeling of DOTA-functionalized biomolecules. An in vivo proof-of-concept study using a DOTA-folate conjugate demonstrated the excellent features of 44Sc for PET imaging. Thus, 44Sc is a valid alternative to 68Ga for imaging and dosimetry before 177Lu-radionuclide tumor therapy.

The effectiveness of a promotora-led intervention for Mexican Americans with type 2 diabetes

Purpose. The purpose of this randomized control repeated measures trial was to determine the effectiveness of a self-management intervention led by community lay workers called promotoras on the health outcomes of Mexican Americans with type 2 diabetes living in a major city on the Texas - Mexico border. The specific aims of this study, in relation to the intervention group participants, were to: (1) decrease the glycosylated hemoglobin (A1c) blood levels at the six-month assessment, (2) increase diabetes knowledge at the three and six-month assessments, and (3) strengthen the participants' beliefs in their ability to manage diabetes at the three and six-month assessments.^ Methods. One hundred and fifty Mexican American participants were recruited at a Catholic faith-based clinic and randomized into an intervention group and a usual-care control group. Personal characteristics, acculturation and baseline A1c, diabetes knowledge and diabetes health beliefs were measured. The six-month, two-phase intervention was culturally specific and it was delivered entirely by promotoras. Phase One of the intervention consisted of sixteen hours of participative group education and bi-weekly telephone contact follow-up. Phase Two consisted of bi-weekly follow-up using inspirational faith-based health behavior change postcards. The A1c levels, diabetes knowledge and diabetes health beliefs were measured at baseline, and three and six months post-baseline. The mean changes between the groups were analyzed using analysis of covariance. ^ Results. The 80% female sample, with a mean age of 58 years, demonstrated very low: acculturation, income, education, health insurance coverage, and strong Catholicism. No significant changes were noted at the three-month assessment, but the mean change of the A1c levels (F (1, 148 = 10.28, p < .001) and the diabetes knowledge scores (F (1, 148 = 9.0, p < .002) of the intervention group improved significantly at six months, adjusting for health insurance coverage. The diabetes health belief scores decreased in both groups.^ Conclusions. This study demonstrated that an intervention led by promotoras could result in decreased A1c levels and increased diabetes knowledge in spite of the very low acculturation, educational level and insurance coverage of the intervention group participants. Clinical implications and recommendations for future research are suggested. ^

El impacto de la globalización en la ciudadanía de las mujeres : el caso de los derechos reproductivos y sexuales en la Argentina

En este artículo intentamos esbozar brevemente la influencia de la "globalización" sobre la ciudadanía de las mujeres en la Argentina, con especial énfasis en cuanto a los derechos reproductivos se refiere. Vale decir, cómo se han conjugado contexto internacional y nacional - tanto desde el punto de vista económico, político, social, etc., como desde el punto de vista del movimiento de mujeres- en relación con el debate sobre derechos sexuales y reproductivos en nuestro país en los últimos años.

Lineamientos para el mejoramiento del hábitat de una comunidad indígena de Tucumán : intervención en un proceso de reconstrucción histórica, cultural y social

El objetivo del proyecto es formular lineamientos base para propuestas de mejoramiento del hábitat en La Angostura en el Valle del Tafí, favoreciendo su actual proceso de desarrollo y fortalecimiento comunitario como pueblo indígena. La Comunidad se encuentra en un proceso de construcción y reafirmación de su identidad como pueblo originario, lo que involucra reivindicaciones ligadas a la preservación de su hábitat, la reconstrucción de su historia, su desarrollo económico, social y el fortalecimiento comunitario en un momento de ocupación descontrolada del territorio por sectores privados para explotar turísticamente la zona; dejando a la comunidad fuera de los procesos de explotación y producción, usando los recursos del área y condenándola a un estado de dominación y dependencia. El 22 de Mayo de 2006 la Convención Constituyente para la reforma de la Constitución de Tucumán incorporó la propuesta de 21 comunidades indígenas que reconoce los derechos como Pueblos Originarios. La Comunidad cuenta con personería jurídica desde el año 2004 y está organizada de acuerdo a las pautas de los pueblos originarios. Un equipo interdisciplinario integrado por profesionales y estudiantes de Arquitectura, Medicina, Historia, Psicología y Psicología Social estudia las condiciones concretas de existencia y el proceso histórico de la comunidad, la migración de jóvenes que no encuentran fuentes de trabajo o estudio, los adultos y viejos que regresan al valle desde la Capital de la Provincia o del País y vuelcan las influencias recibidas, instalando una idea de progreso situada fuera de su pago.

Movimiento de mujeres/feminismo/s : tensiones y desafíos en la Argentina de los noventa

Durante la transición democrática y el primer período de consolidación, los movimientos sociales resurgen y juegan un rol protagónico como portavoces de la sociedad. El movimiento mujeres/feminismo también tiene aquí un nuevo florecimiento. Sin embargo, la “globalización" traerá aparejada algunas consecuencias que repercutirán tanto en el Estado como en el movimiento, dos de los actores/as protagónicos en la definición de políticas públicas con perspectiva de género. Cuáles son los desafíos que se vislumbran, desde el movimiento de mujeres, en orden a la concesión de una ciudadanía plena para las mujeres, luego de esos cambios, es la pregunta que recorre el texto.
