Intersectionality informed and narrative-shifting whole school approaches for LGBTQ+ secondary school student mental health: A UK qualitative study.

School is a key site for prevention and early intervention in public mental health, with sexual and gender minority students being a priority group for action. Context is important in understanding how school inclusion of sexual and gender minorities shapes mental health and well-being, with rapidly changing social and political forces necessitating ongoing research. This coproduced UK secondary school-based study aimed to understand (a) key components of mentally, socially and emotionally healthy school environments for LGBTQ+ students considerate of intersecting minoritised identities; (b) staff information, skills and capacity needs and (c) factors influencing uptake and implementation. Online interviews and focus groups were conducted with 63 participants (22 staff, 32 students (aged 13-19 years), and 9 training providers), diverse in relation to gender and sexual identity, ethnicity, religious and social context. Data were analysed thematically. One overarching theme captured the need for an intersectionality-informed, contextually adaptable, whole school approach which 'shifts the narrative' away from deficit thinking, challenging prevailing cis/heteronormative and White norms. This underpinned four themes: (1) 'Feeling safe, seen and celebrated: embedding intersectional signs, signals and symbols', (2) 'Everyone's business: the need for collaboration', (3) 'Embedding a culture of change', and (4) 'Re-locating the problem: challenging deficit thinking'. Contextually diverse research is needed which critically addresses ways in which social power enacted interpersonally and structurally serves to hinder schools from enacting LGBTQ+ inclusivity. Evidence to inform and develop implementation strategies for institutional changes and to advocate for wider socio-political support is also key to mitigate the potential for widening inequities linked to inequitable school environments.

Effects of task type on spontaneous alternations of attentional states.

Mind wandering is a common occurrence that can have serious consequences, but estimating when mind wandering occurs is a challenging research question. Previous research has shown that during meditation, people may spontaneously alternate between task-oriented and mind-wandering states without awareness (Zukosky & Wang, 2021, Cognition, 212, Article 104689). However, under what conditions such alternations occur is not clear. The present study examined the effects of task type on spontaneous alternations between task focus and mind wandering. In addition to a meditation task, participants performed either a scene-categorization-based CPT or a visual detection task while attentional orientation was assessed via self-monitoring and intermittent probes. The three tasks differ in the extent of their reliance on continuous monitoring (less required in the detection than meditation and CPT tasks) and attentional orientation (oriented internally in meditation task and externally in CPT and detection tasks). To overcome prior methodological challenges, we applied a technique designed to detect spontaneous alternations between focused and mind-wandering states without awareness, based on how the proportion of "focused" responses/ratings to intermittent probes changes during a focus-to-mind-wandering interval (i.e., the period from one self-report of mind wandering to the subsequent self-report). Our results showed that the proportion of "focused" responses to intermittent probes remained constant with increasing interprobe interval during meditation (consistent with previous work), but declined significantly in the CPT and detection tasks. These findings support the hypothesis that spontaneous alternations of attentional states without self-awareness occur during tasks emphasizing internally but not externally oriented attention.

'I probably wouldn't want to talk about anything too personal': A qualitative exploration of how issues of privacy, confidentiality and surveillance in the home impact on access and engagement with online services and spaces for care-experienced young people.

This paper draws on a qualitative interview-based study that explored online mental health and wellbeing interventions and services for care-experienced young people. The study involved young people (n = 4), foster carers (n = 8), kinship carers (n = 2) and social care professionals (n = 9) in Wales, UK. The paper reflects on the complexities of online communication in the space of 'the home'. It documents the ways in which care-experienced young people's living arrangements can restrict access to services and complicate confidentiality within portals to the virtual world, creating an environment where young people and their carers 'wouldn't want to talk about anything too personal'. Drawing on data generated in a study focused on services and interventions to support the mental health and wellbeing of care-experienced children and young people, the paper considers privacy, confidentiality and surveillance in the home and reflects on how associated relational practices impact on care-experienced young people. While the data discussed in this paper was generated during the Covid-19 pandemic, its findings have implications for how care-experienced young people and their carers can be supported to engage with the digital world in the future.

When mental health services are delivered online, they are usually accessed from home. Home can be different for young people who grow up in care, with records kept about their day-to-day activities, a lack of access to the digital world and policy governing how they are able to live their lives. We spoke with young people, foster carers and practitioners about what it is like for young people to access mental health services online. The paper discusses how the private home lives of care-experienced children and young people impacts on how they are able to access much needed mental health services. We look at the need to protect the freedom of children in care and care-experienced young people to take risks and access digital spaces like other children and teenagers do, while also recognising the reality of the pressures on practitioners and carers to protect looked after children from harm.

The Influence of Prestimulus 1/f-Like versus Alpha-Band Activity on Subjective Awareness of Auditory and Visual Stimuli.

Alpha rhythmic activity is often suggested to exert an inhibitory influence on information processing. However, relatively little is known about how reported alpha-related effects are influenced by a potential confounding element of the neural signal, power-law scaling. In the current study, we systematically examine the effect of accounting for 1/f activity on the relation between prestimulus alpha power and human behavior during both auditory and visual detection (N = 27; 19 female, 6 male, 2 nonbinary). The results suggest that, at least in the scalp-recorded EEG signal, the difference in alpha power often reported before visual hits versus misses is probably best thought of as a combination of narrowband alpha and broadband shifts. That is, changes in broadband parameters (exponent and offset of 1/f-like activity) also appear to be strong predictors of the subsequent awareness of visual stimuli. Neither changes in posterior alpha power nor changes in 1/f-like activity reliably predicted detection of auditory stimuli. These results appear consistent with suggestions that broadband changes in the scalp-recorded EEG signal may account for a portion of prior results linking alpha band dynamics to visuospatial attention and behavior, and suggest that systematic re-examination of existing data may be warranted.Significance Statement Fluctuations in alpha band (∼8-12 Hz) activity systematically follow the allocation of attention across space and sensory modality. Increases in alpha amplitude, which often precede failures to report awareness of threshold visual stimuli, are suggested to exert an inhibitory influence on information processing. However, fluctuations in alpha activity are often confounded with changes in the broadband 1/f-like pattern of the neural signal. When both factors are considered, we find that changes in broadband activity are as effective as narrowband alpha activity as predictors of subsequent visual detection. These results are consistent with emerging understanding of the potential functional importance of broadband changes in the neural signal and may have significant consequences for our understanding of alpha rhythmic activity.

Effects of rhythmic auditory stimulation on vision: Oscillations in performance can be enhanced, but not induced.

A variety of reports suggest that rhythmic auditory stimulation can entrain visual perception, inducing perceptual oscillations as a function of time relative to the auditory rhythm. These effects have, to date, been reported only for stimulation frequencies at and below 3 Hz. Here we investigate the effects of rhythmic auditory stimulation on the detection of masked visual targets when this stimulation occurs at frequencies to which the visual system has been shown to entrain (8-12 Hz). Across four experiments, we found no consistent evidence of poststimulation modulations in performance induced by 8.5, 10.6, or 12.1 Hz auditory stimulation. This absence of a consistent auditory-to-visual effect was paralleled by an absence of unimodal effects (oscillations in auditory performance) following 12.1 Hz auditory stimulation. In a fifth experiment, we found that although auditory stimulation alone did not induce oscillations in visual performance, auditory stimulation did enhance the effects of concurrent visual stimulation. Notably, this enhancement did not require synchronous presentation of stimuli. These observations are consistent with recent reports that passive auditory stimulation beyond 5 Hz induces neither auditory perceptual oscillations nor visual cortical oscillations and suggest limits to the extent of cross-modal entrainment.

Use of Digital Whiteboard to Engage Undergraduates in Online Studies of Instructor-Generated Biological Diagrams.

The development of critical thinking skills is one of the core values of higher education. As an important aspect of visual literacy in the core competencies of undergraduate biology teaching, diagram learning activities have been shown to facilitate students' gains in understanding biology concepts and improving critical thinking skills. To address a need to scaffold students' learning processes of the higher-order cognitive skills in Bloom's Taxonomy via diagram, we have developed an instructional tool using diagrams for online and in-person classes. This teaching and learning tool utilizes a digital canvas created in Microsoft Whiteboard. A diagram of a certain complexity is designed and created by the instructor to model the critical thinking linked to the taught content. Students can work simultaneously to fill in the blanks of the diagram using provided terms and phrases that are derived from lecture slides and aligned with course learning objectives. A moderator, either a peer leader or the instructor, can use this online whiteboard to observe and advise students for their study activities and engage students in discussions in real-time. This customized teaching tool may be particularly useful for introductory biology courses to train first-year students and sophomores to learn biological concepts and mechanisms. More importantly, it helps students comprehend and learn the critical thinking skills embedded in the provided diagrams to prepare them to conduct more complex diagram activities and generate their own diagrams.

Identifying Clinical and Genomic Features Associated With Chronic Kidney Disease.

We apply a pattern-based classification method to identify clinical and genomic features associated with the progression of Chronic Kidney disease (CKD). We analyze the African-American Study of Chronic Kidney disease with Hypertension dataset and construct a decision-tree classification model, consisting 15 combinatorial patterns of clinical features and single nucleotide polymorphisms (SNPs), seven of which are associated with slow progression and eight with rapid progression of renal disease among African-American Study of Chronic Kidney patients. We identify four clinical features and two SNPs that can accurately predict CKD progression. Clinical and genomic features identified in our experiments may be used in a future study to develop new therapeutic interventions for CKD patients.

Building the multitasking brain: An integrated perspective on functional brain activation during task-switching and dual-tasking.

Multitasking behavior is associated with well-known performance costs, but the question of why individuals falter when attempting to manage multiple streams of information remains difficult to answer. One reason for this difficulty may be that multitasking costs are often characterized by isolating component processes that are studied largely independently. In this study, we instead integrate two commonly studied substrates of multitasking, task-switching and dual-tasking, within the same procedural context. This method allows not only a direct comparison of performance costs associated with different demand types but also examination of their interaction. We measured functional brain activation in thirty healthy young adults as they completed a block-design version of the task, observing consistent and separable patterns of frontoparietal activation as a function of demand type. Broadly, task-switching was associated with activation of left premotor and inferior parietal regions, and dual-tasking was associated with activation in regions of right prefrontal and inferior parietal cortex. In the interaction condition, we observed a distributed bilateral pattern of activation across the areas associated with each demand in isolation. These results provide both behavioral and neuroimaging evidence that task-switching and dual-tasking demands can be dissociated and contribute to multitasking costs in unique and separable ways.

The effect of Bikram yoga on endothelial function in young and middle-aged and older adults.

The purpose of this investigation was to determine if Bikram yoga, a style of heated hatha yoga, would improve endothelial function in young and middle-aged and older, healthy adults. This trial was performed in 36 young (n = 17) and middle-aged and older adults (n = 19) who completed 3 weekly Bikram yoga classes for 8 weeks. Height, body weight and body composition were determined and endothelial function was measured noninvasively using brachial artery flow-mediated dilation (FMD) before and after the intervention. No changes in body weight, BMI or body fat percentage occurred as a result of the intervention in either group. Brachial artery FMD was significantly increased in middle-aged and older (P < 0.05) but not in young adults as a result of the intervention. The results demonstrate that a relatively short-term Bikram yoga practice might significantly improve vascular endothelial function in middle-aged and older adults. While apparently healthy individuals in this study experienced no adverse events, those with preexisting conditions should take caution and consult with a physician prior to engaging in this style of yoga.

Impact of Hot Yoga on Arterial Stiffness and Quality of Life in Normal and Overweight/Obese Adults.

BACKGROUND: Obesity is associated with arterial stiffening and diminished quality of life. Bikram yoga may be a feasible alternative to traditional exercise among obese individuals. Accordingly, the purpose of this study was to investigate the impact of Bikram yoga, a heated style of hatha yoga, on arterial stiffness in normal and overweight/obese adults. METHODS: Forty-three (23 normal body mass index or BMI; 20 overweight/obese) apparently healthy participants completed an 8-week Bikram yoga intervention. Body composition was estimated via dual energy x-ray absorptiometry, arterial stiffness was measured via brachialankle pulse wave velocity, and health-related quality of life was assessed via RAND 36-Item Short Form survey at baseline and at the end of the 8-week intervention. RESULTS: After the intervention, brachial-ankle pulse wave velocity decreased (P < .05) in overweight/obese participants while no such changes were observed in normal BMI participants. In the quality of life measures, emotional well-being improved (P < .05) in both groups, and general health improved (P < .05) only in the normal weight BMI group. CONCLUSION: Bikram yoga ameliorates arterial stiffness in overweight/obese adults and can positively impact quality of life regardless of BMI.

Evaluation of a clinically practical, ERP-based neurometric battery: Application to age-related changes in brain function.

OBJECTIVE: Event-related potentials (ERPs) show promise as markers of neurocognitive dysfunction, but conventional recording procedures render measurement of many ERP-based neurometrics clinically impractical. The purpose of this work was (a) to develop a brief neurometric battery capable of eliciting a broad profile of ERPs in a single, clinically practical recording session, and (b) to evaluate the sensitivity of this neurometric profile to age-related changes in brain function. METHODS: Nested auditory stimuli were interleaved with visual stimuli to create a 20-min battery designed to elicit at least eight ERP components representing multiple sensory, perceptual, and cognitive processes (Frequency & Gap MMN, P50, P3, vMMN, C1, N2pc, and ERN). Data were recorded from 21 younger and 21 high-functioning older adults. RESULTS: Significant multivariate differences were observed between ERP profiles of younger and older adults. Metrics derived from ERP profiles could be used to classify individuals into age groups with a jackknifed classification accuracy of 78.6%. CONCLUSIONS: Results support the utility of this design for neurometric profiling in clinical settings. SIGNIFICANCE: This study demonstrates a method for measuring a broad profile of ERP-based neurometrics in a single, brief recording session. These markers may be used individually or in combination to characterize/classify patterns of sensory and/or perceptual brain function in clinical populations.

Improvements in glucose tolerance with Bikram Yoga in older obese adults: a pilot study.

Bikram yoga is an exotic form of physical activity combining hatha yoga and thermal therapy that could positively impact metabolic health. Although this increasingly popular alternative exercise may be ideal for obese adults due to its low impact nature, few studies have elucidated the health benefits associated with it. As an initial step, we determined the effect of Bikram yoga on glucose tolerance. Fourteen young lean and 15 older obese subjects completed an 8-week Bikram yoga intervention in which classes were completed 3 times per week. Glucose tolerance was assessed using a 75 g oral glucose tolerance test. The area under the glucose curve following the oral glucose tolerance test was significantly reduced as a result of the Bikram Yoga intervention in older obese (P < 0.05) but not in young lean subjects. We concluded that a short-term Bikram yoga intervention improved glucose tolerance in older obese, but not in young lean adults.

The effect of Bikram yoga on arterial stiffness in young and older adults.

BACKGROUND AND OBJECTIVE: Bikram yoga is the most popular form of hot yoga, despite the limited information available on its cardiovascular benefits. This study sought to determine the effect of Bikram yoga on arterial stiffness and insulin resistance in young and older adults. METHODS: Twenty-four young (mean age±standard deviation, 30±1 years) and 18 middle-aged and older (mean age, 53±2 years) adults completed an 8-week Bikram yoga intervention. Bikram yoga classes were performed for 90 minutes per session, three times per week, in a room heated to 40.5°C with 40%--60% relative humidity. RESULTS: Body mass, body fat percentage, blood pressure, and fasting blood glucose and triglyceride concentrations did not significantly change as a result of the intervention in either the young or the older group. Trunk flexibility, as measured by the sit-and-reach test, increased in both groups (p<0.01). Total (p<0.05) and low-density lipoprotein cholesterol (p<0.05) levels, plasma insulin concentrations (p<0.01), and scores on the homeostatic model of the assessment of insulin resistance (p<0.01) decreased in older adults, whereas total and high-density lipoprotein cholesterol concentrations were reduced in young adults (all p<0.05). Carotid artery compliance (p<0.05) was increased and ß-stiffness index decreased in young (p<0.05) but not in older adults. Carotid pulse pressure did not significantly change in either group. CONCLUSION: A relatively short-term Bikram yoga intervention improved arterial stiffness in young but not older adults and significantly reduced insulin resistance index in older but not young adults.

Surgical treatment of metabolic syndrome.

This article explores the surprising finding that bariatric surgery can produce full and durable remission of the metabolic syndrome as well as other comorbidities of obesity including type II diabetes, hypertension, polycystic ovary syndrome, gastroesophageal reflux disease, nonalcoholic steatotic hepatitis, adult asthma and improvement in weight-bearing arthropathy. Such an outcome was previously deemed impossible. One effect of the surgery is the correction of hyperinsulinemia, a common denominator in the various expressions of the metabolic syndrome. Basal insulin levels return to normal levels within a matter of days following surgery, allowing a return of the first phase of insulin secretion. This effect is 'dose related' to the extent of the reduction of contact between food and the gut. The resolution of the spectrum of diseases that comprise the metabolic syndrome following bariatric surgery suggests that hyperinsulinemia may be the common cause that is corrected by lowering contact between food and the gut. If this concept is true, then the cause of the syndrome, including diabetes, could be a diabetogenic signal from the gut that forces the islets to produce excessive and harmful levels of insulin, or the cause could be the removal of a signal that blocks excessive insulin secretion. If either of these mechanisms is proven correct, the current treatment of diabetes with long-term insulin administration deserves review.
