Numerous studies have shown dysfunctional mechanism of interaction between bottom-up emotional and top-down cognitive processes in persons with schizophrenia (SCZ). During the emotional directed forgetting (DF) paradigm participants have to apply volitional mechanisms to resist automatic emotional enhancement of the memory. Here we sought to compare mechanisms underlying emotional DF in SCZ and in healthy persons (HC). Eighteen SCZ and eighteen HC completed a DF paradigm with neutral and negative pictures. EEG was recorded during study and test phase of the task. We analyzed both the behavioral outcomes and event-related potential components, indicating emotional enhancement of memory (Late Positive Potential elicited by pictures) and DF strategies (N2/P3 elicited by forget/remember cues during study-phase; "old/new" and "reversed old/new" effects during test-phase of the task). Directed forgetting effects and emotional enhancement of memory were observed in both groups, even despite overall lower recognition rates in SCZ. Furthermore, cue presentation elicited similar pattern of N2/P3s in SCZ and in HC. However, "reversed old/new" effect was observed only in HC for negative stimuli. Patients may show similar reaction to affective stimuli as healthy controls during the emotional DF task. However, further investigation is needed to elicit the specific mechanisms underlying the DF strategies in SCZ.

Based on item-method directed forgetting (DF) task, sixty participants were recruited to explore the influence of emotion (negative, neutral, and positive) on memory encoding processing. Behavioral results showed that participants were more successful at remembering negative pictures that needed to be forgotten, with both higher recognition rates and Pr values compared to neutral pictures. In the brain, parietal activities reflected preferential processing during negative picture viewing through enhanced late parietal positive potentials (LPP) relative to neutral ones.

Background: Despite recommendations from clinical practice guidelines to initiate four drug classes in patients with heart failure (HF) with reduced ejection fraction, information on real-world implementation remains limited. This study evaluated the medications initiated and titrated, the time until the optimal treatment tolerated, pharmacological profiles, patient's adherence, and causes of non-use of guideline directed-medical therapy (GDMT) in a cohort of patients with HF.
Methods: A retrospective cohort study was conducted on patients treated in a heart failure program in Colombia.

Background: Low anterior resection (LAR) is the gold standard for curative cancer treatment in the middle and upper rectum. In radically operated patients, the local recurrence rates with total mesorectal excision (TME) after 5 and 10 years was<10%, with 80% in 5 years survival. Anastomotic leakage (AL) affects 4%-20% of patients who underwent LAR.

The item-based directed-forgetting effect is explained as a difference in how strongly people encode remember-cued over forget-cued targets. In contrast, the production effect is typically explained as a difference in the distinctiveness of the memory of produced over unproduced targets. The procedural alignment of the two effects - directing participants to remember or forget, produce or not - coupled with their different theoretical explanations (i.

Background: Pain is the leading cause of disability and reduced quality of life worldwide. Despite the increasing burden for patients and healthcare systems, pain research remains underfunded and under focused. Having stakeholders identify and prioritize areas that need urgent attention in the field will help focus funding topics, reduce 'research waste', improve the effectiveness of pain research and therapy and promote the uptake of research evidence.
