RESUMO

Autonomous sensory meridian response (ASMR) and affective touch (AT) are two phenomena that have been independently investigated from separate lines of research. In this article, I provide a unified theoretical framework for understanding and studying them as complementary processes. I highlight their shared biological basis and positive effects on emotional and psychophysiological regulation. Drawing from evolutionary and developmental theories, I propose that ASMR results from the development of biological mechanisms associated with early affiliative behaviour and self-regulation, similar to AT. I also propose a multimodal interoceptive mechanism underlying both phenomena, suggesting that different sensory systems could specifically respond to affective stimulation (caresses, whispers and affective faces), where the integration of those inputs occurs in the brain's interoceptive hubs, allowing physiological regulation. The implications of this proposal are discussed with a view to future research that jointly examines ASMR and AT, and their potential impact on improving emotional well-being and mental health.

RESUMO

Objectives. To examine whether referral for social determinants of health (SDH) needs decreases psychological distress and posttraumatic stress disorder (PTSD) symptoms and improves level of functioning and quality of care among diverse adults. Methods. Data are from control participants (n = 503 adults) in a randomized controlled trial testing a mental health intervention in North Carolina and Massachusetts. We fitted multilevel mixed-effects models to repeated assessments (baseline, 3, 6, and 12 months) collected between September 2019 and January 2023. Results. After referral to services for trouble paying utility bills, participants reported lower PTSD symptoms. Participants reported better quality of care when receiving referrals to mental health care. After adjusting for income and employment status, we found that participants who were referred more often also had lower PTSD symptoms and better levels of functioning. Conclusions. Referrals for certain SDH needs might decrease PTSD symptoms and improve self-reported quality of care and functioning. However, referrals alone, without ensuring receipt of services, might be insufficient to affect other mental health outcomes. Research is needed on training and providing care managers time for offering interpersonal support, securing services, and understanding agencies' contexts for addressing high SDH needs.

RESUMO

The present 21-day daily diary study (conducted 2021-2022) tested anger and racism-related vigilance as potential transdiagnostic mediators linking exposure to racial and ethnic discrimination (RED) to distress (negative affect and stress, respectively). The data analytic sample included N = 317 Mexican-origin adolescents (Mage = 13.5 years; 50.8% male, 46.7% female; 2.5% non-binary) from the Midwestern United States. Results from longitudinal mediation models revealed significant mediation effects through anger and racism-related vigilance, respectively, in the association between daily RED and daily distress, both within and across adolescents. Implications for theory, research, and practice are discussed so that future work can leverage these novel findings toward promoting the well-being of Mexican-origin adolescents, especially those who live in contexts of ethnoracial adversity.

RESUMO

The current study evaluated cultural values and family processes that may moderate associations between daily racial-ethnic discrimination and distress among Mexican-origin youth. Integrating micro-time (daily diary) and macro-time (longitudinal survey) research design features, we examined familism, family cohesion, and ethnic-racial socialization from youth-, mother-, and father- reports as potential buffers of daily associations between youth racial-ethnic discrimination and youth distress (negative affect and anger). The analytic sample, drawn from the Seguimos Avanzando study, included 317 Mexican-origin adolescents (Mage = 13.5 years) and their parents, recruited from the Midwestern United States. Results indicated that youth-reported familism and family cohesion significantly buffered daily associations between youth racial-ethnic discrimination and youth distress. In contrast, parent-reported familism and family cohesion and some aspects of ethnic-racial socialization exacerbated the discrimination to distress link. The implications of these results are discussed to inform efforts supporting the healthy development of Mexican-origin youth and their families.

RESUMO

BACKGROUND: Racial/ethnic differences in mental health outcomes after a traumatic event have been reported. Less is known about factors that explain these differences. We examined whether pre-, peri-, and post-trauma risk factors explained racial/ethnic differences in acute and longer-term posttraumatic stress disorder (PTSD), depression, and anxiety symptoms in patients hospitalized following traumatic injury or illness. METHODS: PTSD, depression, and anxiety symptoms were assessed during hospitalization and 2 and 6 months later among 1310 adult patients (6.95% Asian, 14.96% Latinx, 23.66% Black, 4.58% multiracial, and 49.85% White). Individual growth curve models examined racial/ethnic differences in PTSD, depression, and anxiety symptoms at each time point and in their rate of change over time, and whether pre-, peri-, and post-trauma risk factors explained these differences. RESULTS: Latinx, Black, and multiracial patients had higher acute PTSD symptoms than White patients, which remained higher 2 and 6 months post-hospitalization for Black and multiracial patients. PTSD symptoms were also found to improve faster among Latinx than White patients. Risk factors accounted for most racial/ethnic differences, although Latinx patients showed lower 6-month PTSD symptoms and Black patients lower acute and 2-month depression and anxiety symptoms after accounting for risk factors. Everyday discrimination, financial stress, past mental health problems, and social constraints were related to these differences. CONCLUSION: Racial/ethnic differences in risk factors explained most differences in acute and longer-term PTSD, depression, and anxiety symptoms. Understanding how these risk factors relate to posttraumatic symptoms could help reduce disparities by facilitating early identification of patients at risk for mental health problems.

RESUMO

BACKGROUND: Parental psychopathology is associated with their children's posttraumatic stress symptoms (PTSS). However, the mechanisms through which this occurs remain unclear. We hypothesized that exposure to childhood adversities is the mechanism linking parental psychopathology to child PTSS and that parenting practices moderated these associations. METHODS: Participants (N = 1,402) with an average age of 24.03 years old (SD = 2.20), were all Puerto Ricans (50% Male and 50% Female) from the Boricua Youth Study, which is a four-wave longitudinal study spanning almost 20 years, following individuals from childhood (ages 5-13 at Wave 1) to young adulthood. Measured variables include parental psychopathology at Wave 1, childhood adversities and parenting practices at Waves 2-3, and PTSS at Wave 4. A traditional mediation model estimated the association between parental psychopathology and child PTSS via childhood adversities. A moderated mediation model was used to examine whether parenting practices moderated this mediation model. RESULTS: Results showed that the total effect of parental psychopathology at Wave 1 on PTSS at Wave 4 was fully mediated by childhood adversities at Waves 2-3 (direct effect b = 1.72, 95% CI = [-0.09, 3.83]; indirect effect b = 0.40, 95% CI = [0.15, 0.81]). In addition, the magnitude of this pathway varied by levels of parenting practices (i.e. parental monitoring and parent-child relationship quality). Specifically, the indirect effect of additional adversities in the psychopathology-PTSS link was stronger with higher levels of parental monitoring but weaker with higher parent-child relationship quality scores. CONCLUSIONS: Intergenerational continuity of psychopathology may be mitigated through the prevention of additional childhood adversities via upstream interventions, emphasizing providing parents with mental health needs with parenting tools. Family-based interventions focused on providing families with the tools to improve parent-child relationships may reduce the negative impact of childhood adversities on mental health across the life course.

RESUMO

Autonomous sensory meridian response (ASMR) describes the experience of a pleasant body sensation accompanied by a feeling of well-being and relaxation in response to specific audiovisual stimuli, such as whispers and personal attention. Previous work suggests a relationship between this experience with the processing of affective and body states; however, no research has explored differences in interoception between people experiencing ASMR and those who do not. We hypothesized that the ASMR experience is based on interoception processing. To test this, we assessed group differences across different dimensions of interoception: Interoceptive sensibility (IS), measured using the multidimensional assessment of interoceptive awareness (MAIA); Interoceptive accuracy score (IAS), measured by calculating performance in a heartbeat counting task (HCT), and the electrophysiological index of interoception, the heartbeat evoked potential (HEP), which was calculated during the HCT and an ASMR tingle reporting task (ASMR-TRT). Our results showed that IS and IAS, dimensions requiring conscious awareness, showed no differences between groups. However, HEP amplitude was larger in the ASMR group in both tasks. We concluded that the ASMR experience is based on an unconscious interoceptive mechanism, reflected by HEP, where exteroceptive social-affective stimuli are integrated to represent a body state of positive affective feelings and relaxation, as has been described for affective touch. The relevance of this finding relies on that interoceptive function, body regulation, and emotional/affective experiences are fundamental for well-being, and the relationship between ASMR and interoception opens the way to future research exploring the causal relationship between them and their potential clinical applications.

RESUMO

Ventricular tachycardias (VT) may initially show beat to beat oscillations but rapidly stabilize into a regular tachycardia with a stable cycle length. A persistently irregular ventricular tachycardia is a rare phenomenon. We report a rare case of an "irregular" ventricular tachycardia with so pronounced oscillations in cycle length that it was initially misdiagnosed as atrial fibrillation with aberrant conduction. This ventricular tachycardia was incessant and resulted in a tachycardia induced cardiomyopathy refractory to several antiarrhythmic drugs. Mapping of the right ventricle demonstrated that the tachycardia had a focal origin in the moderator band close to its insertion into the anterior papillary muscle. Radiofrequency ablation eliminated the tachycardia with eventual normalization of left ventricular function. The moderator band and anterior papillary muscle of the right ventricle are known to be the source of short-coupled ventricular premature beats and regular ventricular tachycardias. However, an "irregular" ventricular tachycardia has not been previously reported to arise from these structures.

RESUMO

Policy Points In low-income communities in the South Bronx and Puerto Rico, Puerto Rican youth are exposed to many of the same risk and protective factors for developing depression, anxiety, or psychological distress; yet it is unclear how the ethnic minority context of the South Bronx and ethnic majority context of Puerto Rico influence risk. Results from our quasi-experimental, longitudinal study demonstrate the importance of addressing social factors (parent-child relationships, youth peer relationships) for youth living in the majority context, and neighborhood and cultural factors (residential mobility, perceived discrimination, perceived social position in the neighborhood) for youth living in the minority context. Our findings support the need for tailoring programs specific to the needs of youth who reside in an ethnic majority or a minority context, since some of the risk factors might operate differently depending on context. Housing and neighborhood environment policies that address discrimination and eliminate structural inequities for ethnic minority groups may protect against the harm of minoritization on young people's mental health. CONTEXT: Puerto Rican youth growing up in low-income communities in the South Bronx and Puerto Rico are exposed to many of the same risk factors for major depressive disorder, generalized anxiety disorder, and psychological distress. One potentially powerful factor differs: Puerto Ricans have been socially marginalized as an ethnic minority group in the South Bronx, but are the ethnic majority of the population in Puerto Rico. A growing body of literature demonstrates the influence of neighborhood, cultural, and social factors and parental psychopathology in the development of mental health problems. An important unanswered question is whether these risk and protective factors have the same impact for youth raised as members of an ethnic majority versus minority group. METHODS: Using a population-based cohort study, with four waves of assessment from early childhood into young adulthood, we investigated whether ethnic minority context alters risk and protective factors for depression, anxiety, and psychological distress. Our longitudinal data set includes 2,491 young children at baseline (82.8% retained at wave 4). Using a quasi-experimental design, we examine how ethnic minority context can alter the development of mental health disorders as Latinx children transition to late adolescence and young adulthood. FINDINGS: Some risk and protective factors operated differently across minority and majority contexts. Higher discrimination and social position were more powerful risk and protective factors, respectively, in the minority context, whereas positive peer relationships mattered more in the majority context. Children of mothers with depression were significantly more likely to develop anxiety in late adolescence and young adulthood in the majority context (60.0%) compared to the minority context (4.5%). CONCLUSIONS: Preventing depression and anxiety disorders in Latinx young adults may require targeting different childhood factors depending on whether they reside within the ethnic majority or minority context. People in the ethnic minority context may benefit more from policies aimed at reducing discrimination and improving economic opportunity, while people in the majority context may benefit more from opportunities for strengthening family and peer relationships.

RESUMO

Lipids fulfill a variety of important physiological functions, such as energy storage, providing a hydrophobic barrier, and signal transduction. Despite this plethora of biological roles, lipids are rarely considered a potential target for medical applications. Here, we report a set of neutral small molecules that contain boronic acid and urea functionalities to selectively recognize the bacterial lipid phosphatidylglycerol (PG). The affinity and selectivity was determined using 1H NMR titrations and a liposome-based Alizarin Red S assay. Minimum inhibitory concentrations (MIC) were determined to assess antibacterial activity. The most potent compounds display an association constant with PG in liposomes of at least 5 × 103 M-1, function as antibacterial agents against Gram-positive bacteria (MIC = 12.5-25 µM), and show little hemolytic activity. Mode of action studies suggest that the boronic acids bind to the headgroup of the PG lipids, which leads to a change in membrane fluidity and ultimately causes membrane depolarization and cell death.

RESUMO

A 55-year-old male presented with acute heart failure and incessant wide complex tachycardia resembling an outflow tract ventricular tachycardia. Meticulous analysis of the electrocardiograms established the diagnosis of pre-excitation with prolonged atrio-ventricular (A-V) conduction over a decrementally conducting accessory A-V pathway. "Linking" between the accessory A-V pathway and normal A-V conduction system resulted in sustained maximal pre-excitation as well as periodic transition to normal A-V conduction without appreciable change in heart rate. Successful radiofrequency ablation of this unusual accessory A-V pathway was performed at the aortic-mitral junction. This ameliorated the mechanical dysynchrony, allowed discontinuation of hemodynamic/inotropic support, and resulted in sustained symptomatic improvement.

RESUMO

Objectives: Emerging adulthood-spanning 18-29 years of age-is associated with the highest risk for onset of certain behavioral health disorders (e.g. major depression, bipolar disorder, psychosis, substance use disorders) and high prevalence of many behavioral health disorders. Yet, rates of mental health service use remain low in this age range. Racial/ethnic minorities are particularly impacted by individual, cultural/linguistic, and community-level barriers to mental health care. This study examined community-level factors associated with mental health service use and investigated whether these associations varied by race/ethnicity.Design: This study analyzed individual- and county-level data for emerging adults in the United States (N=3,294) from the nationally representative Collaborative Psychiatric Epidemiological Surveys (CPES). Using the Andersen Model of Health Care Utilization, analyses examined predisposing, enabling, and need factors utilized in prior studies with adult samples as well as novel community characteristics hypothesized to impact service use among emerging adults of diverse racial/ethnic backgrounds. Past-year use of both specialty and any mental health services were assessed, controlling for individual- and community-level variables, and adjusting for presence of past-year mental health disorder, overall health status, and functional impairment. Differences between racial/ethnic minority groups and Non-Latino Whites were tested through a multilevel model incorporating random intercepts logistic regression, with analysis focusing on the interaction between race/ethnicity and community-level supply variables.Results: For past-year use of specialty mental health services, density of hospitals with child wellness programs was linked to service use among Black emerging adults, whereas density of hospitals with linguistic/translation services was linked to service use among Latino emerging adults.Conclusions: This study expands on previous research in behavioral health disparities to examine ways to improve behavioral health services for an emerging adult population with unmet service needs and identifies specific community-level factors that can improve mental health for racial/ethnic minority emerging adults.

RESUMO

OBJECTIVE: Late life anxiety and depression represent a significant source of disability, with racial/ethnic minority older adults in the U.S. showing marked disparities in healthy aging. Community-based organizations (CBOs) and community clinics serve these populations for preventive care, yet few identify their mental health service needs. We examine the association between race/ethnicity and risk of mild-to-severe symptoms of anxiety and depression, and suicidal behaviors in minority older adults. METHOD: Data come from the multisite randomized controlled trial Building Community Capacity for Disability Prevention for Minority Elders, which screened 1,057 adults (45.5% Asian, 26.8% Latinx, 15.0% non-Latinx Black, 8.5% non-Latinx White, and 4.2% American Indian) aged 60 + years at CBOs and clinics in Massachusetts, New York, Florida, and Puerto Rico. Screened participants completed the Generalized Anxiety Disorder-7 (GAD-7) for anxiety symptoms, the Geriatric Depression Scale-15 (GDS-15) for depression symptoms, and the Paykel Suicide Risk Questionnaire for suicidal behaviors. RESULTS: 28.1% of older adults reported mild-to-severe anxiety symptoms, 30.1% reported mild-to-severe depression symptoms, and 4.3% reported at least one suicidal behavior. Compared to non-Latinx Whites, Latinxs had higher odds of mild-to-severe anxiety and depression symptoms and one or more suicidal behaviors, and Asians had higher odds of mild-to-severe depression symptoms only. CONCLUSIONS: There is an urgent need to improve outreach for screening and preventive mental health care for minority older adults. Expanding outreach and community-based capacity to identify and treat minority older adults with mental health conditions represents an opportunity to prevent disability.

RESUMO

In this review, we provide recent data on the role of mTOR kinase in the brain under physiological conditions and after damage, with a particular focus on cerebral ischemia. We cover the upstream and downstream pathways that regulate the activation state of mTOR complexes. Furthermore, we summarize recent advances in our understanding of mTORC1 and mTORC2 status in ischemia-hypoxia at tissue and cellular levels and analyze the existing evidence related to two types of neural cells, namely glia and neurons. Finally, we discuss the potential use of mTORC1 and mTORC2 as therapeutic targets after stroke.

RESUMO

BACKGROUND AND OBJECTIVES: Recent observations indicate that cannabis use can result in cardiovascular complications including arrhythmias. We studied the relationship between cannabis use disorder (CUD) and arrhythmia hospitalization. METHODS: We conducted a retrospective analysis of the Nationwide Inpatient Sample (2010-2014). Patients (age 15-54) with a primary diagnosis for arrhythmia (N = 570,556) were compared with non-arrhythmia (N = 67,662,082) inpatients for odds ratio (OR) of CUD by the logistic regression model, adjusted for demographics and comorbid risk factors. RESULTS: The incidence of CUD in arrhythmia inpatients was 2.6%. Among cannabis users, the most prevalent arrhythmia was atrial fibrillation (42%), followed by other arrhythmias (24%) and atrial flutter (8%). Patients with CUD were younger (15-24 years, OR: 4.23), male (OR: 1.70), and African American (OR: 2.70). CUD was associated with higher odds of arrhythmia hospitalization in the young population, 1.28 times in 15-24 years (95% confidence interval [CI]: 1.229-1.346) and 1.52 times in 25-34 years (95% CI: 1.469-1.578). CONCLUSION AND SCIENTIFIC SIGNIFICANCE: With the growing legalization in the United States, there is an increased use of medicinal/recreational cannabis. This is the first national study to our knowledge that found that CUD is associated with a 47%-52% increased likelihood of arrhythmia hospitalization in the younger population and the risk of association was controlled for potential confounders including other substances. The fact that atrial fibrillation is the most prevalent arrhythmia is of special concern since it can result in stroke and other embolic events. Physicians need to familiarize themselves with cannabis abuse or dependence as a risk factor for arrhythmia.

RESUMO

INTRODUCTION AND OBJECTIVES: Glecaprevir/pibrentasvir is a highly effective and well tolerated treatment for hepatitis C infection. Brazilian patients were not included in the original development studies for glecaprevir/pibrentasvir. This study aimed to assess safety and efficacy of glecaprevir/pibrentasvir in treatment-naïve Brazilian adults without cirrhosis or with compensated cirrhosis. PATIENTS AND METHODS: EXPEDITION-3 was a Phase 3, open-label, multicenter study in treatment-naïve Brazilian adults with hepatitis C infection genotype 1-6. Patients without cirrhosis (F2 or F3) or with compensated cirrhosis (F4) received 8 or 12 weeks of glecaprevir/pibrentasvir, respectively. The primary efficacy endpoint was the rate of sustained virologic response at post-treatment Week 12. Secondary endpoints were on-treatment virologic failure and relapse rates. Baseline polymorphisms were assessed in NS3 and NS5A. Adverse events and laboratory abnormalities were monitored. RESULTS: 100 patients were enrolled, 75 received 8 weeks of treatment and 25 received 12 weeks; all patients completed treatment. Overall sustained virologic response at post-treatment Week 12 rate was high (98.0%; 98/100; 95% confidence interval: 93.0-99.4) and remained high regardless of baseline viral or host factors, including demographics, hepatitis C virus RNA levels, polymorphisms in NS3 and/or NS5A, genotype, and relevant comorbidities. 55% of patients reported ≥1 adverse event, the most common being headache (18.0%). Four patients reported serious adverse events; none were considered drug related or led to study drug discontinuation. No hepatic decompensations were observed. CONCLUSIONS: Glecaprevir/pibrentasvir was effective and well tolerated in treatment-naïve Brazilian patients with hepatitis C infection without cirrhosis and with compensated cirrhosis. TRIAL REGISTRATION: ClinicalTrials.gov NCT03219216.

RESUMO

In this illustrative case report, we describe a rare case of left posterior fascicular ventricular tachycardia (LPFVT) in a 2 month-old infant with emphasis on electrocardiographic caveats to diagnosis. The clinical course, treatment, and eventual resolution of the VT over a 2 year follow-up is comprehensively compared and contrasted to a modicum of individual such case reports of infants. The corpus of each such case of infantile LPVT is systematically reviewed and succinctly summarized in a tabular compendium. The collective knowledge compiled here should allow for a refined approach to diagnosis and management of this unusual arrhythmia.

RESUMO

In this case report, we describe a 73 year old female with structuraly normal heart that developed shortcoupled torsades de pointes (TdP) resulting in an electrical storm unresponsible to several antiarrhythmic drugs, but fully controlled with verapamil. The critical timing of the ventricular premature beats that initiated TdP corresponded to those that occurred at the peak of the previous T wave. This behavior differentiates this entity from other forms of malignant ventricular arrhythmias in patients with structurally normal heart. It is imperative that the clinical set-up and unique electrocardiographic fingerprint of this unusual malignant entity be assiduously recognized since verapamil can be life-saving in this condition.

RESUMO

BACKGROUND: Sinus P-wave abnormalities have been associated stroke in people with atrial fibrillation (AF). The majority of AF-related strokes occur from left atrial appendage (LAA) thromboembolism. Dysfunction of the left atrium (LA) and left atrial appendage (LAA) can increase rates of thromboembolic stroke. We studied whether abnormal P wave terminal force in V1 (aPTFV1) is associated with decreased LAA ejection velocity (LAAV) on transesophageal echocardiography (TEE). METHODS: We conducted a retrospective cross-sectional study reviewing patients at a tertiary care medical center who underwent TEE in sinus rhythm and had an interpretable sinus ECG within 12 months of TEE. Participants were excluded for complex congenital heart disease, age <18, cardiac transplantation, and chronic atrial pacing. Logistic regression analysis was used to estimate the odds ratios of LAAV<40 cm/s for aPTFV1. RESULTS: In our final cohort of 169 patients (28% of which had LAAV <40), the multivariate odds ratio of aPTFV1 for LAAV<40 cm/s after adjustment for CHA2DS2VASc variables, heart rate during TEE, history of atrial arrhythmias, and left atrial volume index was 2.24 (95% CI of 1.13-6.00). CONCLUSION: Abnromal P-wave terminal force in lead V1 is associated with low LAAV after adjustment for potential confounders. Future research is needed for validation of our findings and determination of clinical utility.

RESUMO

Subjective social status (SSS) has largely been ignored within psychotherapy literature. We investigated the association between similarities in client-clinician perceptions of SSS, similarities in their report of the quality of working alliance, and resultant anxiety symptoms.Participants represented a primarily low-income, culturally diverse sample of 312 clients receiving care from 68 clinicians at 13 outpatient mental health clinics in the Northeastern United States between September 2013 and August 2016. As part of a larger randomized controlled trial, clients and clinicians completed the MacArthur Scale of subjective social status and the Working Alliance Inventory (WAI), and clients completed the Generalized Anxiety Disorder 7-item Scale (GAD-7).At the within-clinician level, client-clinician dyads with less similar perceptions of the client's SSS were characterized by less similar perceptions of their alliance, which in turn resulted in worsening anxiety symptoms.Clinicians' correct perception of their clients' social status might be important for sharing a similar view of the client-clinician level of alliance, which can, in turn, contribute to lowering the client's anxiety symptoms.
