Non-canonical role for Lpar1-EGFP subplate neurons in early postnatal mouse somatosensory cortex.

Subplate neurons (SPNs) are thought to play a role in nascent sensory processing in neocortex. To better understand how heterogeneity within this population relates to emergent function, we investigated the synaptic connectivity of Lpar1-EGFP SPNs through the first postnatal week in whisker somatosensory cortex (S1BF). These SPNs comprise of two morphological subtypes: fusiform SPNs with local axons and pyramidal SPNs with axons that extend through the marginal zone. The former receive translaminar synaptic input up until the emergence of the whisker barrels, a timepoint coincident with significant cell death. In contrast, pyramidal SPNs receive local input from the subplate at early ages but then - during the later time window - acquire input from overlying cortex. Combined electrical and optogenetic activation of thalamic afferents identified that Lpar1-EGFP SPNs receive sparse thalamic innervation. These data reveal components of the postnatal network that interpret sparse thalamic input to direct the emergent columnar structure of S1BF.

An assessment of adherence to CARE reporting standards by case reports published in European Heart Journal - Case Reports in 2018.

BACKGROUND: Case reports are subject to significant variation in their content, and the absence of pertinent case details can limit their benefit to the medical community. To aid this, a reporting standard (CARE) has been developed. Case reports published in European Heart Journal - Case reports (EHJ-CR) are subject to specific checks by editors to confirm compliance with the CARE reporting standard. However, a degree to which case reports published by EHJ-CR comply with the CARE reporting standards has not been established. METHODS: Case reports published in EHJ-CR during 2018 were reviewed for compliance with the CARE reporting standards. Two authors assessed each article for compliance with each of the 31 criteria. RESULTS: In 2018, 130 case reports/series were published by EHJ-CR. The median number of CARE criteria achieved by each article was 21 (interquartile range 21-25) out of 31. CARE criteria with the highest adherence were timeline inclusion, a clear and well-referenced discussion, and declaration of competing interests, all present in 100% of articles. In contrast, some aspects were poorly adhered to including patient perspective, and details of funding sources. There was no difference in overall compliance with aspects of the CARE standard between diagnostic and interventional case reports. However, lower compliance was seen for the discussion of diagnostic challenges in interventional studies (19%), when compared to diagnostic studies (44%). The continent of authorship and month submitted did not affect CARE adherence. CONCLUSIONS: There was good compliance with the CARE reporting standards by case reports published in EHJ-CR. A number of specific areas for improvement have been identified which will be considered by the editorial board of EHJ-CR.
