Abstract

The goal of this study was to compare brain structure between individuals with generalized anxiety disorder (GAD) and healthy controls. Previous studies have generated inconsistent findings, possibly due to small sample sizes, or clinical/analytic heterogeneity. To address these concerns, we combined data from 28 research sites worldwide through the ENIGMA-Anxiety Working Group, using a single, pre-registered mega-analysis. Structural magnetic resonance imaging data from children and adults (5-90 years) were processed using FreeSurfer. The main analysis included the regional and vertex-wise cortical thickness, cortical surface area, and subcortical volume as dependent variables, and GAD, age, age-squared, sex, and their interactions as independent variables. Nuisance variables included IQ, years of education, medication use, comorbidities, and global brain measures. The main analysis (1020 individuals with GAD and 2999 healthy controls) included random slopes per site and random intercepts per scanner. A secondary analysis (1112 individuals with GAD and 3282 healthy controls) included fixed slopes and random intercepts per scanner with the same variables. The main analysis showed no effect of GAD on brain structure, nor interactions involving GAD, age, or sex. The secondary analysis showed increased volume in the right ventral diencephalon in male individuals with GAD compared to male healthy controls, whereas female individuals with GAD did not differ from female healthy controls. This mega-analysis combining worldwide data showed that differences in brain structure related to GAD are small, possibly reflecting heterogeneity or those structural alterations are not a major component of its pathophysiology.

Abstract

Insulin has important vasodilatory effects in the peripheral circulation, but less is known about insulin's role in cerebrovascular control. Herein, we hypothesized both systemic (intravenous) and local (intranasal) insulin administration would increase indices of cerebral blood flow and reduce cerebrovascular compliance (Ci) in young adults. Participants were assigned to one of four separate protocols. Middle cerebral artery blood velocity (MCAv, transcranial Doppler ultrasound) and blood pressure (BP, finger photoplethysmography) were measured at baseline and at 1) 2 min of carbon dioxide (CO2) air breathing (high flow control), 2) 60 min of euglycemic intravenous insulin infusion (40 mU/m2 body surface area/min), 3) 60 min following 160 IU of intranasal insulin, 4) 60 minutes of time control. Ci was calculated (modified Windkessel model). Intravenous insulin increased serum insulin (6.0 ± 2.6 to 52.7 ± 12.7 μIU/mL, P < 0.001), whereas serum insulin was reduced following intranasal insulin (6.9 ± 4.5 to 4.9 ± 1.8 μIU/mL, P = 0.030). MCAv increased in response to CO2 (60 ± 13 to 69 ± 11 cm/s, P < 0.001) but was unchanged with time control (50 ± 7 to 49 ± 8, P = 0.658) and both insulin conditions (intravenous: 61 ± 13 to 62 ± 17 cm/s, P = 0.531; intranasal: 57 ± 12 to 51 ± 15 cm/s; p = 0.061). In contrast, Ci remained at baseline levels over time (P = 0.438) and was reduced from baseline under CO2 and both insulin conditions (CO2, P < 0.001; intravenous, P = 0.021; intranasal, P = 0.001). Contrary to our hypothesis, there was no effect of systemic or local insulin administration on resting MCAv in young adults; however, both systemic and local insulin administration reduced Ci. These findings advance our understanding of the cerebrovascular response to acute insulin exposure. NEW & NOTEWORTHY: Insulin has important vasodilatory effects in the peripheral circulation, but less is known about the role of insulin in cerebrovascular control. Contrary to our hypothesis, there was no effect of systemic (intravenous) nor local (intranasal) insulin administration on middle cerebral artery blood velocity; however, both systemic and local insulin administration reduced cerebrovascular compliance. Our findings advance our understanding of the cerebrovascular response to insulin and may have implications in the context of known metabolic disturbances. [ABSTRACT FROM AUTHOR]

Abstract

Preclinical work supports a role for the peripheral chemoreceptors in the progression of cardiovascular and metabolic pathologies. In the present study, we examined peripheral chemosensitivity in adults with type 2 diabetes (T2D) and the contribution of the peripheral chemoreceptors to resting cardiovascular and metabolic control. We hypothesized that: (1) adults with T2D exhibit exaggerated peripheral chemoreflex sensitivity; (2) the peripheral chemoreceptors contribute to cardiovascular dysfunction in T2D; and (3) attenuation of peripheral chemoreceptor activity improves glucose tolerance in T2D. Seventeen adults with diagnosed T2D [six males/11 females; aged 54 ± 11 years; glycated haemoglobin (HbA1c) 7.6 ± 1.5%] and 20 controls without T2D (9 males/11 females; aged 49 ± 13 years, HbA1c 5.2 ± 0.4%) participated in the study. The hypoxic ventilatory response (HVR) was assessed as an index of peripheral chemosensitivity. Resting heart rate, blood pressure and minute ventilation were measured when breathing normoxic followed by hyperoxic air (1.0FIO2${{F}_{{\mathrm{I}}{{{\mathrm{O}}}_{\mathrm{2}}}}}$) to acutely attenuate peripheral chemoreceptor activity. A subset of participants (n = 9 per group) completed two additional visits [normoxia (0.21FIO2${{F}_{{\mathrm{I}}{{{\mathrm{O}}}_{\mathrm{2}}}}}$), hyperoxia (1.0FIO2${{F}_{{\mathrm{I}}{{{\mathrm{O}}}_{\mathrm{2}}}}}$)] where glucose and insulin were measured for 2 h following an oral glucose challenge. HVR was augmented in adults with T2D (–0.84 ± 0.49 L min–1/%) vs. control (–0.48 ± 0.40 L min–1/%, P = 0.021). Attenuation of peripheral chemoreceptor activity decreased heart rate (P < 0.001), mean blood pressure (P = 0.009) and minute ventilation (P = 0.002); any effect of hyperoxia did not differ between groups. There was no effect of hyperoxia on the glucose (control, P = 0.864; T2D, P = 0.982), nor insulin (control, P = 0.763; T2D, P = 0.189) response to the oral glucose challenge. Peripheral chemoreflex sensitivity is elevated in adults with T2D; however, acute attenuation of peripheral chemoreflex activity with hyperoxia does not restore cardiometabolic function. Key points: Preclinical work supports a role for the peripheral chemoreceptors in the progression of cardiovascular and metabolic pathologies. In the present study, we examined peripheral chemosensitivity in adults with type 2 diabetes and the contribution of the peripheral chemoreceptors to resting cardiovascular control and glucose tolerance. We observed elevated peripheral chemoreflex sensitivity in adults with diabetes which was associated with glycaemic control (i.e. glycated haemoglobin). Notably, acute attenuation of peripheral chemoreflex activity with hyperoxia did not restore cardiometabolic function in the individuals studied. [ABSTRACT FROM AUTHOR]

Abstract

Endothelin‐1 (ET‐1) and its receptors are linked to increases in sensitivity of the chemoreceptors to hypoxic stress and the development of hypertension in preclinical models. We hypothesized ET receptor antagonism would lower resting blood pressure (BP) as well as the acute BP response to chemoreflex stress. Twenty‐four men (31 ± 5 years, 26 ± 3 kg/m2) completed two study visits (control, bosentan). On each visit, BP was assessed under three conditions: (1) normoxia (FiO2 0.21), (2) chemoreflex excitation via hypoxia (FiO2 0.05–0.21), (3) chemoreflex inhibition via hyperoxia (FiO2 1.00). Bosentan increased plasma ET‐1 (0.94 ± 0.90 to 1.27 ± 0.62 pg/mL, p = 0.004), supporting receptor blockade. Resting diastolic (73 ± 5 to 69 ± 7 mmHg, p = 0.007) and mean (93 ± 7 to 88 ± 7 mmHg, p = 0.005) BP were reduced following bosentan compared to control with no change in systolic BP (p = 0.507). The mean BP response to both acute hypoxia (−0.48 ± 0.38 to −0.25 ± 0.31 mmHg/%, p = 0.004) and hyperoxia (area under the curve −93 ± 108 to −27 ± 66 AU, p = 0.018) were attenuated following bosentan. Acute ET receptor inhibition attenuates the rise in BP during chemoreflex excitation as well as the fall in BP during chemoreflex inhibition in healthy young men. These data support a role for ET‐1 in control of resting BP, possibly through a chemoreceptor‐mediated mechanism. [ABSTRACT FROM AUTHOR]

Abstract

There is limited convergence in neuroimaging investigations into volumes of subcortical brain regions in social anxiety disorder (SAD). The inconsistent findings may arise from variations in methodological approaches across studies, including sample selection based on age and clinical characteristics. The ENIGMA-Anxiety Working Group initiated a global mega-analysis to determine whether differences in subcortical volumes can be detected in adults and adolescents with SAD relative to healthy controls. Volumetric data from 37 international samples with 1115 SAD patients and 2775 controls were obtained from ENIGMA-standardized protocols for image segmentation and quality assurance. Linear mixed-effects analyses were adjusted for comparisons across seven subcortical regions in each hemisphere using family-wise error (FWE)-correction. Mixed-effects d effect sizes were calculated. In the full sample, SAD patients showed smaller bilateral putamen volume than controls (left: d = −0.077, pFWE = 0.037; right: d = −0.104, pFWE = 0.001), and a significant interaction between SAD and age was found for the left putamen (r = −0.034, pFWE = 0.045). Smaller bilateral putamen volumes (left: d = −0.141, pFWE < 0.001; right: d = −0.158, pFWE < 0.001) and larger bilateral pallidum volumes (left: d = 0.129, pFWE = 0.006; right: d = 0.099, pFWE = 0.046) were detected in adult SAD patients relative to controls, but no volumetric differences were apparent in adolescent SAD patients relative to controls. Comorbid anxiety disorders and age of SAD onset were additional determinants of SAD-related volumetric differences in subcortical regions. To conclude, subtle volumetric alterations in subcortical regions in SAD were detected. Heterogeneity in age and clinical characteristics may partly explain inconsistencies in previous findings. The association between alterations in subcortical volumes and SAD illness progression deserves further investigation, especially from adolescence into adulthood.

Abstract

There is limited convergence in neuroimaging investigations into volumes of subcortical brain regions in social anxiety disorder (SAD). The inconsistent findings may arise from variations in methodological approaches across studies, including sample selection based on age and clinical characteristics. The ENIGMA-Anxiety Working Group initiated a global mega-analysis to determine whether differences in subcortical volumes can be detected in adults and adolescents with SAD relative to healthy controls. Volumetric data from 37 international samples with 1115 SAD patients and 2775 controls were obtained from ENIGMA-standardized protocols for image segmentation and quality assurance. Linear mixed-effects analyses were adjusted for comparisons across seven subcortical regions in each hemisphere using family-wise error (FWE)-correction. Mixed-effects d effect sizes were calculated. In the full sample, SAD patients showed smaller bilateral putamen volume than controls (left: d = −0.077, pFWE = 0.037; right: d = −0.104, pFWE = 0.001), and a significant interaction between SAD and age was found for the left putamen (r = −0.034, pFWE = 0.045). Smaller bilateral putamen volumes (left: d = −0.141, pFWE < 0.001; right: d = −0.158, pFWE < 0.001) and larger bilateral pallidum volumes (left: d = 0.129, pFWE = 0.006; right: d = 0.099, pFWE = 0.046) were detected in adult SAD patients relative to controls, but no volumetric differences were apparent in adolescent SAD patients relative to controls. Comorbid anxiety disorders and age of SAD onset were additional determinants of SAD-related volumetric differences in subcortical regions. To conclude, subtle volumetric alterations in subcortical regions in SAD were detected. Heterogeneity in age and clinical characteristics may partly explain inconsistencies in previous findings. The association between alterations in subcortical volumes and SAD illness progression deserves further investigation, especially from adolescence into adul

46. Student-Driven Learning: Small, Medium, and Big Steps to Engage and Empower Students

Abstract

Teachers know that their students love to explore and learn. But, how do we make this possible with thirty students, with different needs, learning styles, and backgrounds, all in one small room with one teacher in the class? Designed to help teachers reflect on their current teaching practice, "Student-Driven Learning" suggests small shifts, medium-sized ideas, and big changes that can be made to encourage student engagement through flexible, student-centered learning. Experiential learning that is student-driven fosters autonomy and shifts the focus from the knowledge and influence of the teacher to the experiences of the students. "Student-Driven Learning" helps teachers introduce opportunities for students to learn their own way, to take initiative, and to experience, wonder, and create.
