Unlabelled: To test the effect of a new decision support tool for acute appendicitis and assess its efficacy and acceptability.
Background: Mounting evidence from randomized controlled trials have shown that antibiotics can be a safe and effective treatment for appendicitis. Patients and surgeons must work together to choose the optimal treatment approach for each patient based on their own preferences and values. We developed a decision support tool to facilitate shared decision-making for appendicitis and its effect on decisional outcomes remains unknown.
Methods: We conducted an online randomized field test in at-risk individuals comparing the decision support tool to a standard infographic. Individuals were randomized 3:1 to view the decision support tool or infographic. The primary outcome was the total decisional conflict scale (DCS) score measured before and after exposure to the decision support tool. Secondary outcomes included between-group DCS scores, and between-group comparisons of the acceptability.
Results: One hundred eighty individuals were included in the study. Total DCS scores decreased significantly after viewing the decision support tool (59 [95% confidence interval (CI): 55-63] to 15 [95% CI: 12-17], < 0.001) representing movement from a state of high to low decisional conflict. Individuals exposed to the decision support tool reported higher acceptability ratings (3.7 [95% CI: 3.6-3.8] vs 3.3 [95% CI: 3.2-3.5] out of 4) and demonstrated increased willingness to consider both treatment options.
Conclusions: These data support the further use and testing of this novel decision support tool in patients with acute appendicitis.

Neurocysticercosis (NCC) is caused by the invasion of larvae in the central nervous system (CNS) and stands as the predominant cause of epilepsy and other neurological disorders in many developing nations. NCC diagnosis is challenging because it relies on brain imaging exams (CT or MRI), which are poorly available in endemic rural or resource-limited areas. Moreover, some NCC cases cannot be easily detected by imaging, leading to inconclusive results.

Background: Esophageal carcinoma (EC) presents a significant public health issue in China, with its prognosis impacted by myriad factors. The creation of a reliable prognostic model for the overall survival (OS) of EC patients promises to greatly advance the customization of treatment approaches.
Aim: To create a more systematic and practical model that incorporates clinically significant indicators to support decision-making in clinical settings.

Background: Within the United States, White individuals experience a higher risk of atrial fibrillation (AF) while exhibiting a lower AF-related stroke risk compared to other ethnic groups. It is possible that these observations stem from phenomena unique to the United States, such as differential health care access. The United Kingdom provides socialized medicine, which ostensibly promotes equitable health care access.

Individuals with developmental disabilities make their own stylistic contributions to text written with physical facilitation.

Introduction: For individuals with developmental disabilities (DD) such as autism, Down syndrome, or cerebral palsy, learning to express with language is a two-fold challenge because atypical cognitive capacity is compounded by sensorimotor coordination deficits. One approach to assisting linguistic expression in these individuals is to physically support them, for example, by touching their torso or arm as they type. The neurophysiological mechanism of such motor assistance for linguistic expression is not known, but recently it has been proposed that light touch may reduce the cognitive load associated with the sensorimotor coordination of typing, thereby releasing shared cognitive resources to the task of generating content.
