Social skills probably emerge from the interaction between different neural processing levels. However, social neuroscience is fragmented into highly specialized, rarely cross-referenced topics. The present study attempts a systematic reconciliation by deriving a social brain definition from neural activity meta-analyses on social-cognitive capacities. The social brain was characterized by meta-analytic connectivity modeling evaluating coactivation in task-focused brain states and physiological fluctuations evaluating correlations in task-free brain states. Network clustering proposed a functional segregation into (1) lower sensory, (2) limbic, (3) intermediate, and (4) high associative neural circuits that together mediate various social phenomena. Functional profiling suggested that no brain region or network is exclusively devoted to social processes. Finally, nodes of the putative mirror-neuron system were coherently cross-connected during tasks and more tightly coupled to embodied simulation systems rather than abstract emulation systems. These first steps may help reintegrate the specialized research agendas in the social and affective sciences.
During the past decade, novel approaches to study social interaction have expanded and questioned long-standing knowledge about how humans understand each other. We aim to portray and reconcile the key psychological processes and neural mechanisms underlying navigation of the social environment. Theoretical accounts mostly revolved around either abstract inferences or embodied simulations, whereas experimental studies mostly focused on theory of mind or mentalizing, empathy, and action imitation. The tension between theories of and experiments on social cognition is systematically revisited to foster new theoretical and empirical studies in the fields. We finally retrace differential impairments in social capacities as a means to re-conceptualize psychopathological disturbance in psychiatry, including schizophrenia, borderline personality, and autism.
1001 Background: Cyclin-dependent kinases 4 and 6 inhibitors (CDK4/6i) in combination with ET has become a standard first-line treatment for pts with endocrine-sensitive, HR[+]/HER2[-] ABC. The optimal treatment after progression on a CDK4/6i remains unknown. This study aims to determine if P maintenance with an alternative ET improves the antitumor activity of second-line treatment in this patient population. Methods: A total of 198 pts with HR[+]/HER2[-] ABC who had disease progression to first-line P plus ET (aromatase inhibitor or fulvestrant) were included. Pts were eligible if they had clinical benefit to the first-line treatment defined as response or stable disease ≥24 weeks, or who had progressed on a P-based regimen in the adjuvant setting with disease progression after at least 12 months of treatment but no more than 12 months following P treatment completion. Pts were randomly assigned (2:1 ratio) to receive P plus second-line ET (letrozole or fulvestrant, based on prior ET) or second-line ET alone. Stratification factors were prior ET and the presence of visceral involvement. Primary endpoint was investigator-assessed progression-free survival (PFS) determined by RECIST v.1.1. Secondary endpoints included overall response rate (ORR), clinical benefit rate (CBR), overall survival, and safety. The 2-sided log-rank test (α = 0.05) had an 80% power to detect a hazard ratio ≤0.59 in favor of P maintenance. Results: Between April 2019 and October 2022, 136 and 62 pts were randomized to receive P+ET and ET, respectively. Pts characteristics were well balanced. Median age was 59 years (range: 33-85), 61.1% were ECOG 0, 61.1% had visceral disease, and 89.9% received aromatase inhibitor + P as first-line treatment for metastatic disease. At median follow-up of 8.7 months and 155 PFS events, median investigator-assessed PFS was 4.2 months (95% CI 3.5–5.8) in the P+ET vs. 3.6 months (95% CI 2.7–4.2) in the ET arm (hazard ratio 0.8, 95% CI 0.6–1.1, p=0.206). This result was consistent across all stratification subgroups. 6-month PFS rate was 40.9% and 28.6% for P+ET and ET, respectively. Among 138 pts with measurable disease, no significant differences were observed in ORR (6.4% vs. 2.3%) or CBR (33.0% vs. 29.5%) for P+ET and ET, respectively. Grade 3-4 adverse events were higher in pts treated with P+ET (45.2% vs. 8.3%) and no new safety signals were identified. No treatment-related deaths were reported. Conclusions: For HR[+]/HER2[-] ABC pts, maintaining P with a second-line ET beyond progression on prior P-based therapy did not significantly improve PFS compared with second-line ET alone. Planned biomarker analysis may help identify which pts are more likely to benefit from this therapeutic approach. Clinical trial information: NCT03809988 .
