Pupillometry has a rich history in the study of perception and cognition. One perennial challenge is that the magnitude of the task-evoked pupil response diminishes over the course of an experiment, a phenomenon we refer to as a fatigue effect. Reducing fatigue effects may improve sensitivity to task effects and reduce the likelihood of confounds due to systematic physiological changes over time.

Micro-LEDs (µLEDs) have been explored for augmented and virtual reality display applications that require extremely high pixels per inch and luminance. However, conventional manufacturing processes based on the lateral assembly of red, green and blue (RGB) µLEDs have limitations in enhancing pixel density. Recent demonstrations of vertical µLED displays have attempted to address this issue by stacking freestanding RGB LED membranes and fabricating top-down, but minimization of the lateral dimensions of stacked µLEDs has been difficult.

Alpha-synucleinopathies can be identified in their prodromal phase, raising several ethical issues. In this review, we first provide definitions of prodromal α-synucleinopathies and discuss the importance of distinguishing between prodromes and risk factors. Next, we discuss the implications of a diagnosis of prodromal α-synucleinopathy and considerations regarding prognostic counseling in both clinical and research settings.

Optimal mating decisions depend on the robust coupling of signal production and perception because independent changes in either could carry a fitness cost. However, since the perception and production of mating signals are often mediated by different tissues and cell types, the mechanisms that drive and maintain their coupling remain unknown for most animal species. Here, we show that in behavioral responses to, and the production of, a putative inhibitory mating pheromone are co-regulated by , a member of the gene family.

Introduction: Underlying factors associated with alcohol hangover psychological symptoms, such as anxiety and depression, have not been identified. Emotion dysregulation and repetitive negative thinking (RNT) are transdiagnostic factors associated with psychopathology, including non-hangover anxiety and depression. The current study prospectively examined the role of emotion dysregulation on subsequent alcohol hangover anxiety and depression symptoms, as well as the moderating role of RNT on this relation among university students.

Article Synopsis
  • This study examines the effect of active esophageal cooling versus traditional temperature monitoring during pulmonary vein isolation (PVI) for treating atrial fibrillation (AF), highlighting its potential for reducing esophageal injuries.
  • Data from 513 patients were analyzed at a 1-year follow-up, revealing a significant improvement in freedom from AF for patients receiving active cooling (72.2%) compared to those monitored with temperature probes (58.2%).
  • The findings suggest that active esophageal cooling may lead to better long-term outcomes for AF patients undergoing ablation, with a notable reduction in arrhythmia recurrence rates.

Clinical Epidemiology Center, Research and Development Service, VA Saint Louis Health Care System, Saint Louis, MO, USA; Nephrology Section, Medicine Service, VA Saint Louis Health Care System, Saint Louis, MO, USA; Veterans Research and Education Foundation of Saint Louis, Saint Louis, MO, USA; Department of Medicine, Washington University School of Medicine, Saint Louis, MO, USA; Institute for Public Health, Washington University in Saint Louis, Saint Louis, MO, USA. Electronic address:

Background: Non-clinical evidence and a few human studies with short follow-ups suggest increased risk of dyslipidaemia in the post-acute phase of COVID-19 (ie, >30 days after SARS-CoV-2 infection). However, detailed large-scale controlled studies with longer follow-ups and in-depth assessment of the risks and burdens of incident dyslipidaemia in the post-acute phase of COVID-19 are not yet available. We, therefore, aimed to examine the risks and 1-year burdens of incident dyslipidaemia in the post-acute phase of COVID-19 among people who survive the first 30 days of SARS-CoV-2 infection.

Background: As operative techniques and mortality rates of pancreatectomy have improved, there has been a shift in focus to maintaining and improving the nutritional status of these patients as we continue to learn more about post-operative complications. Although pancreatic endocrine and exocrine insufficiencies are known complications of pancreatectomy, increased longevity of these patients has also led to a higher incidence of fatty liver disease which differs from traditional fatty liver disease given the lack of metabolic syndrome.

Aim: To identify and summarize patterns and risk factors of post-pancreatectomy fatty liver disease to guide future management.
