Energy Supplementation during the Last Third of Gestation Improves Mother-Young Bonding in Goats.

We tested whether maternal energy supplementation during the last third of gestation improves birth weight, neonatal wellbeing, and mother-young bonding. Thirty-six pregnant French Alpine goats were randomly allocated among three nutritional treatments for the last third of pregnancy: (i) Control, fed alfalfa (T-0; n = 12); (ii) alfalfa + 150 g/head daily energy concentrate (T-150; n = 12); (iii) alfalfa + 300 g/head daily energy concentrate (T-300; n = 12). At birth, we collected progeny data on birth weight, birth type, sex, rectal temperature, heart rate, respiratory rate, time to standing, time to udder connection, and time to first feeding. For the dams, we collected data on the duration of labor, time to clean the progeny, and time to allow first suckling. At birth, body weight, rectal temperature, heart rate, and the respiratory rate did not differ among treatments (p > 0.05). In the dams, labor duration was not affected by the treatments (p > 0.05). The T-150 dams were faster to clean the newborn and allow first suckling (p < 0.05). The T-150 progeny were faster to stand and the T-300 progeny were faster to connect to the udder (p < 0.05). We conclude that energy supplementation of the dam during the last third of gestation does not affect the birth weight of the progeny, but enhances the mother-young bonding.

[Unusual cyanosing heart defect due to supravalvular tricuspid obstruction in an infant]. / Una forma rara de cardiopatía cianosante por obstrucción supravalvular tricuspídea en el lactante.

We present a case involving a rare form of cyanotic congenital heart disease in a 2-month-old neonate. The initial diagnosis was thought to be tricuspid dysplasia with right-to-left shunting through an interatrial communication. However, surgery showed the presence of a pedunculated mass that prolapsed into the tricuspid valve orifice, thereby causing severe obstruction to right ventricular filling. This mass was attached to the lower part of the atrial septum. Pathological examination showed fibrotic myxoid tissue. After the mass was resected surgically, the tricuspid valve appeared normal. We comment on the pathogenesis and the differential diagnosis of this rare entity.

Presentamos el caso de un lactante de 2 meses con cianosis desde el primer día de vida. El diagnóstico de sospecha inicial fue displasia tricuspídea, con shunt derecha-izquierda a través de una comunicación interauricular. Fue necesario llegar al acto quirúrgico para objetivar un «bolsón» de tejido supratricuspídeo adherido al septo interauricular bajo, que dificultaba el llenado del ventrículo derecho. Tras su resección se evidenció el aspecto macroscópico normal de la válvula tricúspide. La histología fue compatible con tejido fibromixoide. Se discuten la etiopatogenia y posibilidades diagnósticas de este hallazgo inhabitual
