Background: The technical skills of a surgeon influence surgical outcome. Testing technical aptitude at point of recruitment of surgical residents is only conducted in a few countries. This study investigated the impact of visuospatial ability (VSA), background factors, and manual dexterity on performance in two different laparoscopic surgical simulators amongst applicants and 1st year surgical residents.
Method: Applicants from general surgery, pediatric surgery, and urology were included from seven hospitals in Sweden between 2017 and 2021. Some 73 applicants were invited and 50 completed. Participants filled out a background form, and were tested for manual dexterity, and visuospatial ability. Two laparoscopic simulators were used, one 2D video box trainer and one 3D Virtual Reality Simulator.
Results: A significant association was found between the visuospatial ability test and 2D video box laparoscopic performance (95 % CI: 1.028-1.2, p-value <0.01). For every point on the visuospatial test the odds of accomplishing the task increased by 11 %. No association was found between VSA and performance in a laparoscopic VR simulator using 3D vision. No other background factors were associated with performance in the two laparoscopic simulators.
Conclusion: Visuospatial ability in applicants to surgical residency positions is associated to performance in a 2D video box trainer. Knowledge of a resident's visuospatial ability can be used to tailor individualized laparoscopic training programs, and in the future might function as a selection tool concerning laparoscopic ability.
Key Message: Visuospatial ability differs greatly amongst applicants for surgical residency and is associated to laparoscopic simulator performance. Testing applicants' visuospatial ability could possibly be used to tailor individualized laparoscopic training programs or in the future as a selection tool concerning laparoscopic ability.

Background: The influence of alcohol use on later neurocognitive functioning is well researched, yet few studies have investigated whether neurocognition post-drinking initiation in adolescence predicts changes in later alcohol use.
Objective: Investigate neurocognitive task performance during maximum alcohol use in late adolescence as predictors of drinking behaviors 3-7 years later.
Methods: Analyses () were conducted on a longitudinal dataset involving adolescents (12-13 years-old) who were followed for 16 years.

Background: Neurodevelopmental conditions often exhibit overlapping symptoms, posing challenges for differential diagnosis. Developmental Coordination Disorder (DCD) manifests as fundamental motor impairments, often along with co-occurring visuospatial difficulties. Nonverbal Learning Disorder (NLD) features visuospatial core challenges, with a less consistent characterization of its motor profile.

Cerebral visual impairment (CVI) is a brain-based visual disorder associated with injury and/or maldevelopment of central visual pathways. Visuospatial processing impairments are a cardinal feature of the complex clinical profile of individuals with CVI. Here, we assessed visuospatial processing abilities using a classic conjunction search task.

Purpose: The aim of the study is to analyze and compare the cognitive profile between 59 patients with long-COVID [LC; 30 of them with and 29 without a positive coronavirus disease 2019 (COVID-19) confirmatory test] and 31 patients with postural orthostatic tachycardia syndrome (POTS) and a matched group of 39 healthy control participants.
Methods: Participants were examined on a battery of neuropsychological tests, including verbal memory, visuospatial abilities, attention, processing speed, verbal fluency, working memory, and visual memory. Anxious-depressive symptomatology was also analyzed and then controlled for possible influence on cognitive performance.

Objective: Cognitive impairment is increasingly recognized as a complication of diabetes, yet the underlying pathology remains unclear. This study aims to investigate the roles of inflammation, oxidative stress, endothelial dysfunction, and neuronal damage in the neuropathology underlying diabetes related cognitive impairment.
Methods: This study assessed 183 participants (54 prediabetes, 71 Type 2 diabetes mellitus [T2DM], and 58 controls) for cognitive performance using the Montreal Cognitive Assessment (MoCA).
