The impact of prenatal alcohol exposure on hippocampal-dependent outcome measures is influenced by prenatal and early-life rearing conditions.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe clinical course of individuals exposed to alcohol in utero is influenced by multiple factors, including the social environments of the gravid female and offspring. In the present studies we focused on the effects of prenatal alcohol exposure (PAE) and the prenatal and early-life social environments on the hippocampal formation, as impaired development and functioning of this brain region have been implicated in several of the adverse cognitive outcomes associated with PAE.
methodsWe combined our PAE mouse model with 2 conditions of housing pregnant dams and their preweanling offspring: the standard nest (SN), in which a dam is individually housed prior to parturition and then remains isolated with her offspring, and the communal nest (CN), in which multiple dams are housed together prior to parturition and then following delivery the moms and their litters share a nest. Mouse dams consumed either 10% (w/v) ethanol in 0.066% (w/v) saccharin (SAC) or 0.066% (w/v) SAC alone using a limited (4-hour) access, drinking-in-the-dark paradigm. Immunoblotting techniques were used to measure levels of the glucocorticoid receptor (GR), 11-β-hydroxysteroid dehydrogenase 1, the FK506-binding proteins 51 and 52, and corticotropin-releasing hormone receptor type 1 in the hippocampal formation isolated from male adolescent offspring. We also determined the effect of PAE and rearing conditions on context discrimination, a hippocampal-dependent learning/memory task.
resultsSN PAE offspring displayed impaired context discrimination and neurochemical changes in the hippocampal formation consistent with increased GR nuclear localization. These effects of PAE were, in general, ameliorated in mice reared in a CN. The CN also altered neurochemical measures and improved learning/memory in SAC control animals.
conclusionsThese studies demonstrate a complex interplay between the effects of PAE and social environments. The findings have important translational implications, as well as highlight the importance of considering rearing conditions in the interpretation of research findings on PAE.
