ObjectiveObesity is associated with increased cancer risk. Because of the substantial and sustained weight loss following bariatric surgery, postsurgical patients are ideal to study the association of weight loss and cancer.MethodsRetrospectively (1982–2019), 21,837 bariatric surgery patients (surgery, 1982–2018) were matched 1:1 by age, sex, and BMI with a nonsurgical comparison group. Procedures included gastric bypass,… Continue reading Long-term #cancer outcomes after #bariatric surgery

Interaction of an α-synuclein epitope with HLA-DRB1∗15:01 triggers enteric features in mice reminiscent of prodromal #Parkinson’s disease
•α-syn32-46 immunization of HLA-DRB1∗15:01 mice triggers weight loss and constipation•α-syn32-46 immunizations induce inflammation and neuron loss in the gut•Depletion of CD4+, but not CD8+, T cells partially rescues enteric neural loss•Both α-syn32-46 and HLA-DRB1∗15:01 are critical for this model of prodromal PD SummaryEnteric symptoms are hallmarks of prodromal Parkinson’s disease (PD) that appear decades before the onset of motor… Continue reading Interaction of an α-synuclein epitope with HLA-DRB1∗15:01 triggers enteric features in mice reminiscent of prodromal #Parkinson’s disease
Higher working #memory capacity and distraction-resistance associated with strategy (not action) #game playing in younger adults, but #puzzle game playing in older adults
Superior attention and Working Memory (WM) have been reported for habitual action video gamers compared to other gamers or non-players. With an online experiment we measured visuo-spatial WM capacity and ability to ignore distraction, and participants listed the video games they played. Categorising the 209 young adult participants (18–30 years) according to the game type… Continue reading Higher working #memory capacity and distraction-resistance associated with strategy (not action) #game playing in younger adults, but #puzzle game playing in older adults
Speakers of different #languages remember #visual scenes differently
Language can have a powerful effect on how people experience events. Here, we examine how the languages people speak guide attention and influence what they remember from a visual scene. When hearing a word, listeners activate other similar-sounding words before settling on the correct target. We tested whether this linguistic coactivation during a visual search… Continue reading Speakers of different #languages remember #visual scenes differently
American #Football Play and #Parkinson Disease Among Men
Importance Parkinsonism and Parkinson disease (PD) are known to result from repetitive head impacts from boxing. Repetitive head impacts from American football may also be associated with increased risk of neurodegenerative pathologies that cause parkinsonism, yet in vivo research on the association between football play and PD is scarce and limited by small samples and equivocal… Continue reading American #Football Play and #Parkinson Disease Among Men
The contribution of secondhand tobacco #smoke to blood #lead levels in US children and adolescents: a cross-sectional analysis of NHANES 2015–2018
Lead is a major developmental neurotoxicant in children, and tobacco smoke has been suggested as a source of lead exposure in vulnerable populations. This study evaluates the contribution of secondhand tobacco smoke (SHS) to blood lead levels (BLLs) in children and adolescents.MethodsWe analyze data from 2,815 participants aged 6–19 years who participated in the National Health… Continue reading The contribution of secondhand tobacco #smoke to blood #lead levels in US children and adolescents: a cross-sectional analysis of NHANES 2015–2018
Regional, circuit and network heterogeneity of #brain abnormalities in #psychiatric disorders
The substantial individual heterogeneity that characterizes people with mental illness is often ignored by classical case–control research, which relies on group mean comparisons. Here we present a comprehensive, multiscale characterization of the heterogeneity of gray matter volume (GMV) differences in 1,294 cases diagnosed with one of six conditions (attention-deficit/hyperactivity disorder, autism spectrum disorder, bipolar disorder,… Continue reading Regional, circuit and network heterogeneity of #brain abnormalities in #psychiatric disorders
Recovery #sleep following sleep restriction is insufficient to return elevated daytime heart #rate and systolic blood #pressure to baseline levels
Objective Sleep restriction alters daytime cardiac activity, including elevating heart rate (HR) and blood pressure (BP). There is minimal research on the cumulative effects of sleep loss and the response after subsequent recovery sleep on HR and BP. This study examined patterns of HR and BP across baseline, sleep restriction, and recovery conditions using multiple daytime cardiac… Continue reading Recovery #sleep following sleep restriction is insufficient to return elevated daytime heart #rate and systolic blood #pressure to baseline levels
Dietary wheat #gluten induces astro- and #microgliosis in the hypothalamus of male mice
Gluten, which is found in cereals such as wheat, rye and barley, makes up a major dietary component in most western nations, and has been shown to promote body mass gain and peripheral inflammation in mice. In the current study, we investigated the impact of gluten on central inflammation that is typically associated with diet-induced… Continue reading Dietary wheat #gluten induces astro- and #microgliosis in the hypothalamus of male mice
