The primary motor cortex (M1) is essential for voluntary fine-motor control and is functionally conserved across mammals¹. Here, using high-throughput transcriptomic and epigenomic profiling of more than 450,000 single nuclei in humans, marmoset monkeys and mice, we demonstrate a broadly conserved cellular makeup of this region, with similarities that mirror evolutionary distance and are consistent between the transcriptome and epigenome. The core conserved molecular identities of neuronal and...

The neocortex is disproportionately expanded in human compared with mouse^(1,2), both in its total volume relative to subcortical structures and in the proportion occupied by supragranular layers composed of neurons that selectively make connections within the neocortex and with other telencephalic structures. Single-cell transcriptomic analyses of human and mouse neocortex show an increased diversity of glutamatergic neuron types in supragranular layers in human neocortex and pronounced...

Plasmablastic lymphomas and plasmablastic myelomas are malignancies with overlapping clinical and pathological features which pose a diagnostic dilemma and are known to be aggressive with a poor outcome. CD38 is a common immunophenotypic maker for both these malignancies and provides a rationale for using daratumumab-based regimes. We describe a 57-year-old male with a history of end-stage renal disease who underwent a deceased-donor renal transplant maintained on chronic immunosuppression who...

Central obesity with cardiometabolic syndrome (CMS) is a major global contributor to human disease, and effective therapies are needed. Here, we show that cyclic GMP-selective phosphodiesterase 9A inhibition (PDE9-I) in both male and ovariectomized female mice suppresses preestablished severe diet-induced obesity/CMS with or without superimposed mild cardiac pressure load. PDE9-I reduces total body, inguinal, hepatic, and myocardial fat; stimulates mitochondrial activity in brown and white fat;...

CONCLUSION: Plaque inflammation-related ^(18)FDG uptake improved identification of 5-year recurrent ipsilateral ischaemic stroke. Addition of plaque inflammation to current selection strategies may target patients most likely to have late as well as early benefit from carotid revascularization.

CONCLUSION: Our IPDMA of DIA/DIG cases reported in the literature revealed that GTR was a predictor of survival while leptomeningeal metastasis at presentation was associated with mortality. Deep tumor location and chemotherapy were associated with tumor recurrence / progression.

CONCLUSIONS: Embolization and surgery for unruptured high-grade dAVFs afforded a greater likelihood of obliteration than did observation. Embolization also reduced the risk of death and dAVF-associated hemorrhage compared with conservative management over a modest follow-up period. These findings support embolization as the first-line treatment of choice for appropriately selected unruptured Borden type II and III dAVFs.

In nearly all clinical and research contexts, the initial severity of a traumatic brain injury (TBI) is measured using the Glasgow Coma Scale (GCS) total score. However, the GCS total score may not accurately reflect level of consciousness, a critical indicator of injury severity. We investigated the relationship between GCS total scores and level of consciousness in a consecutive sample of 2,455 adult subjects assessed with the GCS 69,487 times as part of the multi-center Transforming Research...

Mounting evidence suggests the synaptic vesicle glycoprotein 2A (SV2A) targeted by levetiracetam may contribute to epileptogenesis. Levetiracetam has shown anti-inflammatory, antioxidant, neuroprotective and possible antiepileptogenic effects in brain injury and seizure/epilepsy models, and a phase 2 study has signaled a possible clinical antiepileptogenic effect. Brivaracetam shows greater affinity and specificity for SV2A than levetiracetam and broader preclinical anti-seizure effects. Thus,...

CONCLUSIONS: Endovascular reintervention for aortic pathology was associated with higher mortality than was primary EVAR. Reinterventions after prior OAPs were associated with higher mortality than were prior EVARs.

CONCLUSION: This study is the first randomized controlled trial of a manualized psychodynamic intervention for children with ODD. Participants demonstrated significant reductions in symptoms of ODD after 10 weeks of treatment. Further investigation is needed to compare RFP-C relative to active treatment, assess changes in implicit emotion, and to determine long-term maintenance of symptom improvement.Clinical trial registration information: Evaluation of Regulation Focused Psychotherapy for...

CONCLUSIONS: At 12-months post-TBI, older adults endorse lower depressive symptoms than their younger counterparts and are less likely to experience major depression; however, over one-fourth of older adults endorsed symptoms consistent with depression, warranting evaluation and treatment.

CONCLUSIONS AND RELEVANCE: In this cohort study of patients with CVST, a distinct clinical profile and high mortality rate was observed in patients meeting criteria for TTS after SARS-CoV-2 vaccination.

CONCLUSIONS: A syndrome of severe fatigue and other constitutional symptoms is a rare but clinically significant side effect of hyperresponse to clopidogrel in patients undergoing neuroendovasular intervention.

CONCLUSIONS: The Northern Ireland population has a relatively high prevalence of OS compared with other European countries. OS presenting with only ocular involvement progressed to second organ involvement in 80% of patients at a rate of 14%/person-years. Raised intra-ocular pressure with or without glaucomatous damage was a frequent finding. Thoracic CT imaging should be requested if clinical suspicion of OS exists and the presence of lymphopenia has utility in diagnosis with concurrent use of...

Intussusception is the most common cause of bowel obstruction in infants four to ten months old and is commonly idiopathic or attributed to lymphoid hyperplasia. Our patient was a 7-month-old male who presented with two weeks of intermittent abdominal pain associated with crying, fist clenching and grimacing. Ultrasound demonstrated an ileocolic intussusception in the right abdomen. Symptoms resolved after contrast enemas, and he was discharged home. He re-presented similarly the next day and...

CONCLUSION: In this large cohort of ICI-treated patients, a higher risk was observed for skeletal myopathies and elevation in CK levels in patients undergoing concurrent statin therapy. Prospective observational studies are warranted to further elucidate the potential association between statin use and ICI-associated myopathies.

Certain clinical indications and treatments such as the use of rasburicase in cancer therapy and 8-aminoquinolines for Plasmodium vivax malaria treatment would benefit from a point-of-care test for glucose-6-phosphate dehydrogenase (G6PD) deficiency. Three studies were conducted to evaluate the performance of one such test: the STANDARD™ G6PD Test (SD BIOSENSOR, South Korea). First, biological interference on the test performance was evaluated in specimens with common blood disorders, including...

OBJECTIVE: Our purpose was to characterize neuropsychological evaluation (NP) outcome following functional hemispherectomy in a large, representative cohort of pediatric patients.
