Social inattentional blindness to idea stealing in meetings.

Using a virtual reality social experiment, participants (N = 154) experienced being at the table during a decision-making meeting and identified the best solutions generated. During the meeting, one meeting participant repeated another participant's idea, presenting it as his own. Although this idea stealing was clearly visible and audible, only 30% of participants correctly identified who shared the idea first. Subsequent analyses suggest that the social environment affected this novel form of inattentional blindness. Although there was no experimental effect of team diversity on noticing, there was correlational evidence of an indirect effect of perceived team status on noticing via attentional engagement. In sum, this paper extends the inattentional blindness phenomenon to a realistic professional interaction and demonstrates how features of the social environment can reduce social inattention.

Factors affecting the GABAergic synapse function in Alzheimer's disease: Focus on microRNAs.

Alzheimer's disease (AD) is a progressive neurological disease characterized by the loss of cognitive function, confusion, and memory deficit. Accumulation of abnormal proteins, amyloid beta (Aß), and phosphorylated Tau (p-tau) forms plaques and tangles that deteriorate synapse function, resulting in neurodegeneration and cognitive decline in AD. The human brain is composed of different types of neurons and/or synapses that are functionally defective in AD. The GABAergic synapse, the most abundant inhibitory neuron in the human brain was found to be dysfunctional in AD and contributes to disrupting neurological function. This study explored the types of GABA receptors associated with neurological dysfunction and various biological and environmental factors that cause GABAergic neuron dysfunction in AD, such as Aß, p-tau, aging, sex, astrocytes, microglia, APOE, mental disorder, diet, physical activity, and sleep. Furthermore, we explored the role of microRNAs (miRNAs) in the regulation of GABAergic synapse function in neurological disorders and AD states. We also discuss the molecular mechanisms underlying GABAergic synapse dysfunction with a focus on miR-27b, miR-30a, miR-190a/b, miR-33, miR-51, miR-129-5p, miR-376-3p, miR-376c, miR-30b and miR-502-3p. The purpose of our article is to highlight the recent research on miRNAs affecting the regulation of GABAergic synapse function and factors that contribute to the progression of AD.

Mitochondria Localized microRNAs: An Unexplored miRNA Niche in Alzheimer's Disease and Aging.

Mitochondria play several vital roles in the brain cells, especially in neurons to provide synaptic energy (ATP), Ca2+ homeostasis, Reactive Oxygen Species (ROS) production, apoptosis, mitophagy, axonal transport and neurotransmission. Mitochondrial dysfunction is a well-established phenomenon in the pathophysiology of many neurological diseases, including Alzheimer's disease (AD). Amyloid-beta (Aß) and Phosphorylated tau (p-tau) proteins cause the severe mitochondrial defects in AD. A newly discovered cellular niche of microRNAs (miRNAs), so-called mitochondrial-miRNAs (mito-miRs), has recently been explored in mitochondrial functions, cellular processes and in a few human diseases. The mitochondria localized miRNAs regulate local mitochondrial genes expression and are significantly involved in the modulation of mitochondrial proteins, and thereby in controlling mitochondrial function. Thus, mitochondrial miRNAs are crucial to maintaining mitochondrial integrity and for normal mitochondrial homeostasis. Mitochondrial dysfunction is well established in AD pathogenesis, but unfortunately mitochondria miRNAs and their precise roles have not yet been investigated in AD. Therefore, an urgent need exists to examine and decipher the critical roles of mitochondrial miRNAs in AD and in the aging process. The current perspective sheds light on the latest insights and future research directions on investigating the contribution of mitochondrial miRNAs in AD and aging.

'I like to protect my protector': How US-born Latinos safeguard the livelihood of their immigrant communities from immigration enforcement encounters.

Using a qualitative phenomenological design, the objective of this study was to explore in-depth how US-born Latinos provide social support to their immigrant counterparts during a time of heightened anti-immigrant rhetoric. A sample of 22 US-born Latino adult was recruited in 2019 for qualitative interviews, following a period of intense immigration raids. Eligible participants were adults who reported experiencing an immigration-related stressor and screened positive for a mental health concern or substance misuse. Open-ended questions focused on topics of immigration and health. Using a thematic analysis approach, interview transcripts were coded to identify common themes within the domains of social support: instrumental; informational; emotional; and appraisal. We found that US-born Latinos provide diverse forms of social support to immigrants with the intention of protecting them from immigration enforcement encounters (e.g. deportation), thereby safeguarding the livelihoods of their communities. US-born Latinos are integral pillars of support and resiliency for immigrant communities, and the domains identified within this study suggest important implications for immigrant health.

The Impact of Natural Disasters on Maternal Health: Hurricanes Irma and María in Puerto Rico.

The PROTECT research Center funded by the NIH's National Institute of Environmental Health Sciences (NIEHS) Superfund Research Program was launched in 2010 to explore the impact of exposure to pollutants on the high rate of premature births in Puerto Rico. In September 2017, Hurricanes Irma and María devastated the archipelago, which caused: collapse of the electrical system, collapse of the communication system, limited access to clean water, food, gas, and health services, destruction of public (e.g., hospitals) and private property (e.g., houses) and more than 4500 deaths. Pregnant and postpartum individuals are especially vulnerable to natural disasters. They face difficulty obtaining adequate pre- and post-natal care, are exposed to increased risk of miscarriage, premature delivery, and giving birth to low birth weight babies during and after disasters and are also more likely to suffer physical and mental health problems compared to the general population during and after disasters. A face-to-face questionnaire was administered to PROTECT participants who were pregnant during hurricanes Irma or Maria or who became pregnant shortly after in order to identify hurricane-related sources of stress and other adverse effects. This paper is based on the answers to the open-ended question at the end of the questionnaire where participants were asked to share their experiences during and after the hurricanes. Among the 375 participants who completed the survey, 76 answers to the open-ended question were considered due to data saturation. The answers to the open-ended question were transcribed into a document in order to facilitate the coding process. The transcribed text was analyzed first to identify emerging categories and then coded to identify common themes as well as divergence among participants. The following themes were identified: pregnancy and birth challenges, lack of access to basic services, housing conditions, stressful working conditions, concerns about health, concerns about their children, and positive or protective aspects. The results indicate how the disruption in access to basic services has a unique impact on the physical and mental health of pregnant and post-partum women in an emergency situation. These findings point to the potential benefit of developing specific protocols designed for emergency preparedness aimed at this population, which can inform healthcare providers and community organizations in case of future events.

Barriers and Strategies for Recruitment of Racial and Ethnic Minorities: Perspectives from Neurological Clinical Research Coordinators.

INTRODUCTION: Randomized controlled trials (RCTs) are the gold standard within evidence-based research. Low participant accrual rates, especially of underrepresented groups (e.g., racial-ethnic minorities), may jeopardize clinical studies' viability and strength of findings. Research has begun to unweave clinical trial mechanics, including the roles of clinical research coordinators, to improve trial participation rates. METHODS: Two semi-structured focus groups were conducted with a purposive sample of 29 clinical research coordinators (CRCs) at consecutive international stroke conferences in 2013 and 2014 to gain in-depth understanding of coordinator-level barriers to racial-ethnic minority recruitment and retention into neurological trials. Coded transcripts were used to create themes to define concepts, identify associations, summarize findings, and posit explanations. RESULTS: Barriers related to translation, literacy, family composition, and severity of medical diagnosis were identified. Potential strategies included a focus on developing personal relationships with patients, community and patient education, centralized clinical trial administrative systems, and competency focused training and education for CRCs. CONCLUSION: Patient level barriers to clinical trial recruitment are well documented. Less is known about barriers facing CRCs. Further identification of how and when barriers manifest and the effectiveness of strategies to improve CRCs recruitment efforts is warranted.
