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
Cross-sectional Survey of Medical student perceptions of And desires for Research and Training pathways (SMART): an analysis of prospective cohort study of UK medical students
Objective: Clinician-scientists are critical to medical innovation and research. However, the number of clinician scientists in the UK has been declining steadily over the last decade. One of the cited reasons is poor student recruitment to academic training pathways. The SMART study aims to assess current student perceptions on research and identify key factors influencing whether a student is interested in research. Design: We conducted a cross-sectional survey study between January and May 2022. Setting: This was a multi-centre national study with data collected across 40 universities offering medical courses in the UK. Participants: Participants were UK medical students enrolled in medicine for 21/22 academic year. Main outcome and measure: The main outcomes were related to participant perceptions on research and whether they were interested in engaging with research in their future career. These measures were correlated with demographic and non-demographic details using regression analyses. Results: One thousand seven hundred seventy-four individuals participated in the SMART survey from 40 medical schools. Nearly half the participants felt there were barriers preventing them from doing research (46.67%) and almost three-quarters felt it was at least somewhat difficult to combine research with medical school (73.49%). Of the options available, most commonly students did not want to pursue an academic career (43.11%) or training pathway (42.49%). However, most participants felt it was useful to do research at medical school (59.54%) and were also interested in doing more research in the future (69.16%). Regression analysis identified many factors influencing student’s perceptions of research including year of study, gender, socioeconomic status, family background, research exposure at medical school, ethnicity, and country of pre-university education. Conclusions: The SMART study is the first of its kind in the UK, shedding light on medical student perceptions. While some express strong interest in academic careers, a larger proportion show a broader interest in research. Demographic factors like gender, parental occupation, and socioeconomic status play a role. Further exploration is needed for specific groups to address barriers, promote research, and boost academic pathway recruitment

Care and three-year outcomes of children with Benign Epilepsy with Centro-Temporal Spikes in England.
PURPOSE: Benign Epilepsy with Centro-Temporal Spikes (BECTS) is a pediatric epilepsy with typically good seizure control. Although BECTS may increase patients' risk of developing neurological comorbidities, their clinical care and short-term outcomes are poorly quantified. METHODS: We retrospectively assessed adherence to National Institute for Health and Care Excellence (NICE) guidelines relating to specialist referral, electroencephalogram (EEG) conduct and annual review in the care of patients with BECTS, and measured their seizure, neurodevelopmental and learning outcomes at three years post-diagnosis. RESULTS: Across ten centers in England, we identified 124 patients (74 male) diagnosed with BECTS between 2015 and 2017. Patients had a mean age at diagnosis of 8.0 (95% CIÂ =Â 7.6-8.4) years. 24/95 (25%) patients were seen by a specialist within two weeks of presentation; 59/100 (59%) received an EEG within two weeks of request; and 59/114 (52%) were reviewed annually. At three years post-diagnosis, 32/114 (28%) experienced ongoing seizures; 26/114 (23%) had reported poor school progress; 15/114 (13%) were diagnosed with a neurodevelopmental disorder (six autism spectrum disorder, six attention-deficit/hyperactivity disorder); and 10/114 (8.8%) were diagnosed with a learning difficulty (three processing deficit, three dyslexia). Center-level random effects models estimated neurodevelopmental diagnoses in 9% (95% CI: 2-16%) of patients and learning difficulty diagnoses in 7% (95% CI: 2-12%). CONCLUSIONS: In this multicenter work, we found variable adherence to NICE guidelines in the care of patients with BECTS and identified a notable level of neurological comorbidity. Patients with BECTS may benefit from enhanced cognitive and behavioral assessment and monitoring
