RESUMO

In this article we investigate the societal implications of empathic artificial intelligence (AI), asking how its seemingly empathic expressions make people feel. We highlight AI's unique ability to simulate empathy without the same biases that afflict humans. While acknowledging serious pitfalls, we propose that AI expressions of empathy could improve human welfare.

RESUMO

In making the case that "rationalization is rational," Cushman downplays its signature liability: Rationalization exposes a person to the hazard of delusion and self-sabotage. In paradigm cases, rationalization undermines instrumental rationality by introducing inaccuracies into the representational map required for planning and effective agency.

RESUMO

Epilepsy, including the type with focal onset, is increasingly viewed as a disorder of the brain network. Here we employed the functional connectivity (FC) metrics estimated from the resting state functional MRI (rsfMRI) to investigate the changes of brain network associated with focal epilepsy caused by single cerebral cavernous malformation (CCM). Eight CCM subjects and 21 age and gender matched controls were enrolled in the study. Seven of 8 CCM subjects underwent surgical resection of the CCM and became seizure free and 4 of the surgical subjects underwent a repeat rsfMRI study. We showed that there was both regional and global disruption of the FC values among the CCM subjects including decreased in homotopic FC (HFC) and global FC (GFC) in the regions of interest (ROIs) where the CCMs were located. There was also the disruption of the default mode network (DMN) especially the FC between the middle prefrontal cortex (MPFC) and the right lateral parietal cortex (LPR) among these individuals. We observed the trend of alleviation of these disruptions after the individual has become seizure free from the surgical resection of the CCM. Using a voxel-based approach, we found the disruption of the HFC and GFC in the brain tissue immediately adjacent to the CCM and the severity of the disruption appeared inversely proportional to the distance of the brain tissue to the lesion. Our findings confirm the disruption of normal brain networks from focal epilepsy, a process that may be reversible with successful surgical treatments rendering patients seizure free. Some voxel-based metrics may help identify the epileptogenic zone and guide the surgical resection.

RESUMO

BACKGROUND: Every day thousands of surgeons and patients negotiate their way through the complex process of decision-making about operative treatments. We conducted a series of qualitative studies, asking patients and surgeons to describe their experience and beliefs about informed decision-making and consent. This study focuses on surgeons' views. METHODS: Open-ended interviews and focus group discussions were conducted with thoracic surgeons who treated esophageal cancer patients by esophagectomy, and general surgeons who routinely performed laparoscopic cholecystectomy. Their views were analyzed using a qualitative approach, grounded in the perspectives of the participants. RESULTS: Five dominant themes emerged from the analysis: (1) making informed decisions; (2) communicating information and confidence; (3) managing expectations and fears; (4) consent as a decision to trust; (5) commitment inspired by trust. These themes are illustrated by verbatim quotes from the surgeon interviews. CONCLUSIONS: Surgeons carefully assess the risks and benefits of treatment before consenting to perform operative interventions. They are influenced by objective findings and by affective factors such as courage and the determination to survive expressed by their patients. They manage risks, doubts, and fears-both their patients' and their own-relying on trust and commitment on both sides to ensure the success of the surgical mission. The trust of their patients has a strong influence on the surgeons' decisions and actions.

RESUMO

BACKGROUND: Although experts in ethics and law prescribe autonomous decision making as an essential component of informed consent to operative treatment, patients with esophageal cancer told us in a previous study that they preferred to entrust decision making to their caregivers in the context of life-threatening illness. The purpose of this study was to describe the patients' perspective on the process of informed decision making and consent to operative treatment in the context of a less frightening illness and intervention. STUDY DESIGN: Face-to-face interviews with 33 patients recovering from elective cholecystectomy for cholelithiasis were conducted at Toronto General Hospital in Ontario, Canada. The views of patients were analyzed using a qualitative approach. RESULTS: Patients described a spectrum of initial attitudes toward operative treatment ranging from profound distrust to unquestioning faith. Important factors influencing the decision to accept cholecystectomy included increasingly intolerable symptoms and fear of complications of the disease. Patients managed their doubts and fear by various means, without fully resolving them. CONCLUSIONS: In the context of symptomatic chronic cholelithiasis, pathways to consent for operative treatment originated at diverse, culturally determined starting points. Patients work their way through the decision process along many paths. Some rely on gathering information, but eventually all set aside unresolved residual doubts and fears, enabling a leap to trust and a decision to act.
