Our findings suggest that 3-dimensional ultrasonographically derived measurements are reliable and reproducible up to 30 weeks if a standard measurement technique is used.

Este artículo identifica y describe preliminarmente una nueva dimensión del dinero que emerge gracias a la implementación masiva de transferencias monetarias para el desarrollo. Concentrándonos en las expectativas educativas que las transferencias monetarias del programa Asignación Universal por Hijo (AUH) promueven entre sus receptoras en la ciudad de Paraná (Provincia de Entre Ríos, Argentina), y en particular en las interfaces monetarias de sus unidades domésticas, descubrimos que, aunque el estado argentino con la finalidad de terminar con la pobreza de la próxima generación pretenda incentivar y condicionar prácticas maternales y educativas, en la mayoría de los casos analizados las transferencias no redundan en una inversión significativa en la educación de sus beneficiarios. Este dinero, sin embargo, al enfrentarse y compararse con otros dineros, principalmente los provenientes de los salarios informales del esposo o concubino, reproduce expectativas vitales que son condición de posibilidad de cualquier mejora educativa. Las mujeres administradoras al reconocer en las transferencias un dinero vital para sus hijos, pero semánticamente muy poco significativo, instauran al mismo tiempo que nuevas posibilidades de perfeccionar consumos y cuidados, una dimensión dineraria que hemos denominado "el ombligo del dinero".

Leptin, a recently described type-1 cytokine, is involved in cellular maturation and growth and appears to have a relationship to some obstetrical and gynecologic diseases. The MEDLINE database was accessed, and leptin-related articles published during the past 6 years were reviewed for their relevance to gynecologic and obstetrical diseases. The relationships between this cytokine and obesity, puberty, polycystic ovary syndrome, endometriosis, assisted fertility, and menopause are discussed. The role of leptin in fetal physiology and in normal and abnormal fetal growth as well as its role in diabetes, pregnancy, and pregnancy-induced hypertension are reviewed.

Despite the fact that the GNPRH centers included in this study represent some of the best health care available in these countries, they lag far behind centers in developed countries in neonatal mortality rates and their use of various obstetric practices. Furthermore, incomplete and inconsistent data collection complicates the evaluation of the factors contributing to high neonatal mortality rates.

Gastric cancer liver metastasis (GCLM) is a contraindication for surgical treatment in current guidelines. However, the results of recent studies are questioning this paradigm. We assessed survival outcomes and their predictors following hepatectomy for GCLM in a systematic review of studies published from 2000 to 2022 according to PRISMA guidelines. We identified 42,160 references in four databases. Of these, 55 articles providing data from 1990 patients fulfilled our criteria and were included. We performed a meta-analysis using random-effects models to assess overall survival (OS) and disease-free survival (DFS) at one, three, and five years post-surgery. We studied the impact of potential prognostic factors on survival outcomes via meta-regression. One, three, and five years after surgery, OS was 69.79%, 34.79%, and 24.68%, whereas DFS was 41.39%, 23.23%, and 20.18%, respectively. Metachronous presentation, well-to-moderate differentiation, small hepatic tumoral size, early nodal stage, R0 resection, unilobar compromisation, and solitary lesions were associated with higher overall survival. Metachronous presentation, smaller primary tumoral size, and solitary metastasis were linked to longer DFS. The results of our meta-analysis suggest that hepatectomy leads to favorable survival outcomes in patients with GCLM and provides data that might help select patients who will benefit most from surgical treatment.
