A groundbreaking critical introduction to folk music and song focused on questions of identity, community, representation, politics, and popular culture. Written by a distinguished international team of authors, this Companion is an indispensable resource for rethinking the confluence of sound, heritage, and identity in the twenty-first century. A unique addition to the literature, it highlights the fundamentally hybrid and (post)colonial dynamics that have shaped people's cultures around the globe, from the Appalachian mountains to the Indian subcontinent. It provides students with new critical paradigms essential for understanding how and why certain musical traditions have been characterised as 'folk'-and what continues to inspire folkloric imaginaries today. The twenty specially commissioned chapters explore folk music from a variety of perspectives including ethnography, revivalism, migration, race, class, gender, protest, and the public sphere. Among these chapters are four 'Artist Voices' by world-renowned performers Peggy Seeger, Angeline Morrison, Jon Boden, and Yale Strom.
Optimizing antibiotic prescribing for urinary tract infections (UTI) represents an opportunity for ambulatory antibiotic stewardship programs (ASPs). A pre-populated order panel for UTI was implemented in the Mayo Clinic Enterprise in May 2022. The order panel provides antibiotic regimens aligning with institutional guidelines according to patient characteristics, presence or absence of complicating features, and antimicrobial allergy status. We assessed impacts of panel use on prescribing practices for cystitis.
Methods:
This retrospective cohort study of ambulatory encounters with a primary diagnosis of cystitis from May 16, 2022, to May 15, 2023, compared encounters in which the order panel was utilized to encounters managed without the panel. The primary outcome was concordance with institutional guidelines, including drug selection, dose/frequency, and duration. Secondary outcomes included rate of repeat healthcare contact for UTI within 14 days and total duration of therapy.
Results:
793 randomly selected patient encounters (397 panel and 396 non-panel) were included. Prescribing was guideline adherent in 79.3% and 64.9% (P < 0.001) of panel and non-panel encounters, respectively. There were more 3- and 5-day treatment courses in the panel cohort; however, inappropriate duration of therapy was the most common reason for non-concordance in both cohorts. There was no significant difference between groups in repeat 14-day healthcare contact for UTI (13.4% panel vs 11.1% no panel, P = 0.34).
Conclusion:
Use of a pre-populated ambulatory order panel for the treatment of cystitis was associated with greater concordance with institutional guidelines, without adversely impacting repeat healthcare contact for UTI.
Regional accent biases in 27 Essex five-year-olds are investigated. This study is the first to analyse implicit language attitudes by measuring children’s neural activity (event-related potentials) while they take part in an Implicit Association Test. Both measures find a preference towards the prestigious accent, Standard Southern British English (SSBE), which is associated with cleverness (CLEVER). A late positive potential in the brain data for the association of the familiar, low-prestige Essex accent with CLEVER suggests the children also have a positive association with their home accent. The association between the less familiar, low-prestige Yorkshire accent and either CLEVER or NOT-CLEVER depends on the measure. Differences in the results are found relating to the children’s accent exposure; those with a more heterogenous group of caretakers show more positive bias towards all three accents overall. Consequences for modelling the development of language attitudes are discussed.
Objectives/Goals: Explore and compare the functional mechanisms of song-based exercises compared to speech-language pathology exercises for dysphagia. The long-term goal is to increase patient outcomes through song-based programs that are accessible, enjoyable, and personalizable. Methods/Study Population: We will pilot the use of combined electroencephalography (EEG) and electromyography (EMG) technologies to analyze both central and peripheral contributors to laryngeal control in a cohort of healthy individuals. This approach provides detailed insight into the coordination between neural and muscular activity, which will serve as a baseline for future studies in clinical populations. Song-based vocal exercises will be compared with standard dysphagia exercises prescribed by speech-language pathologists to assess their mechanistic differences. Results/Anticipated Results: We anticipate identifying specific song-based tasks, such as variations in pitch, rhythm, and intensity, which differentially impact laryngeal musculature. Additionally, we will localize neural activation hotspots using EEG during these tasks, providing a more comprehensive understanding of how song-based therapy influences both peripheral and central mechanisms. Discussion/Significance of Impact: This project will lay the groundwork for developing evidence-based song-based therapies for dysphagia, providing an alternative to traditional SLP exercises. By creating an engaging therapeutic program, we aim to reduce dysphagia’s healthcare burden, including aspiration events, healthcare costs, and related mortality.
Patients with Opioid Use Disorder (OUD) are prone to Multidrug-Resistant Organism (MDRO) colonization and infections, thus at risk for worse outcomes during critical illness. Understanding the prevalence and predictors of MDRO infections is essential to optimize interventions and treatments.
Design:
Retrospective cohort study.
Methods:
The study evaluated the prevalence of MDRO isolation among adults with OUD admitted to an intensive care unit (ICU) between January 1, 2018, and July 31, 2023. It included adults admitted to an ICU with bacterial infections and positive cultures obtained within 48 hours of admission. Demographics, clinical traits, and MDRO isolation rates were analyzed using descriptive statistics, univariate methods, and Least Absolute Shrinkage and Selection Operator (LASSO) regression.
Results:
MDRO isolation occurred in 178 of 790 patients (22.5%), with methicillin-resistant Staphylococcus aureus as the most frequently isolated organism. LASSO regression identified housing insecurity (OR: 1.79, 95% CI 1.09–2.93, P = .022), no receipt of medications for OUD treatment (OR: 1.56, 95% CI 1.06–2.29, P = .023), positive hepatitis C virus (HCV) status (OR: 2.19, 95% CI 1.19–4.03, P = .012), and intravenous antibiotic use in the prior 90 days (OR: 1.04 per 24 h, 95% CI 1.01–1.07, P = .007) as significant predictors of MDRO isolation.
Conclusions:
The study highlights a high prevalence of MDRO isolation in critically ill OUD patients admitted for infection-related issues with positive cultures obtained within 48 hours of admission, influenced by factors like housing insecurity, no receipt of medications for OUD treatment, HCV status, and prior antibiotic use.
Brain immune privilege for many years overshadowed investigation of interaction between the nervous and immune systems. Over time, however, evidence of their interdependence has emerged. In the 1970s, as antibody-mediated autoimmunity was being defined, the neurological disorder myasthenia gravis was shown to be due to autoantibodies that could be passively transferred to mice and removed from humans by plasma exchange. In the 1980s, Fink and Weihe showed that neurons innervate lymph nodes, and from the 1990s onwards, Rothwell and colleagues observed the impact of soluble inflammatory mediators on behaviour. For example, in a key experiment, her team showed that systemic and intraventricular injection of IL-1 led to fever and reduced food motivation in experimental animals, interpreted as “sickness behaviour”; this technique is now used as a model for inflammation-driven depression. Furthermore, IFN- α was unexpectedly found to cause depression when given as a treatment for hepatitis C. More recently, diseases have been identified in which autoantibodies interfere with neuronal function and cause severe psychiatric symptoms, such as N-Methyl D-Aspartate Receptor (NMDAR)-antibody encephalitis. There is now emerging interest in the patho-aetiological role of the immune system in various severe mental illnesses, and the use of immunotherapies in their treatment.
This article examines photographs taken by U.S. Marine Joe O'Donnell, who was tasked with documenting bombed urban centers immediately after the Asia-Pacific War. O'Donnell's photos document not just the physical damage wrought by U.S. bombing raids, but the human suffering as well. While most published images at the time projected the U.S. military's destructive potential through mushroom clouds or razed cities, O'Donnell shifted the visual focus to the struggles of Japanese citizens in the ruins. In doing so, O'Donnell disrupted notions of American superiority by giving voice to those rebuilding their lives in the war's aftermath.
We obtain asymptotics for the average value taken by a Vassiliev invariant on knots appearing as periodic orbits of an Axiom A flow on $S^3.$ The methods used also give asymptotics for the writhe of periodic orbits. Our results are analogous to those of G. Contreras [Average linking numbers of closed orbits of hyperbolic flows. J. Lond. Math. Soc. (2)51 (1995), 614–624] for average linking numbers.
In recent years, there have been increasing calls for the development and growth of the biosocial as a paradigm through which to tackle complex problems. The use of birth cohorts, mixed methods frameworks, and interdisciplinary work are common in biosocial research. However, these practices are also theoretically and practically complex due to epistemic, methodological, and academic challenges – particularly for early career researchers (ECRs) who face time constraints, funding limitations, and disciplinary expectations.
This paper draws on lessons from the experiences of ECRs in biosocial research by reflecting on theoretical heterogeneity, the necessity of translation and negotiation across disciplines and methodologies, and the practicalities of funding, collaboration, and dissemination. Throughout, the paper discusses strategies to overcome common challenges and provide suggestions for fellow ECRs and those interested in biosocial ECR training and development. The paper highlights the importance of strong networks with senior biosocial researchers and peers, the value of practical support, and the importance of formal and informal learning opportunities. The authors call for the enthusiasm for biosocial research to be matched with investment in the development and support for ECRs.
Most people with mental illness in low and middle-income countries (LMICs) do not receive biomedical treatment, though many seek care from traditional healers and faith healers. We conducted a qualitative study in Buyende District, Uganda, using framework analysis. Data collection included interviews with 24 traditional healers, 20 faith healers, and 23 biomedical providers, plus 4 focus group discussions. Interviews explored treatment approaches, provider relationships, and collaboration potential until theoretical saturation was reached. Three main themes emerged: (1) Biomedical providers’ perspectives on traditional and faith healers; (2) Traditional and faith healers’ views on biomedical providers; and (3) Collaboration opportunities and barriers. Biomedical providers viewed faith healers positively but traditional healers as potentially harmful. Traditional and faith healers valued biomedical approaches while feeling variably accepted. Interest in collaboration existed across groups but was complicated by power dynamics, economic concerns, and differing mental illness conceptualizations. Traditional healers and faith healers routinely referred patients to biomedical providers, though reciprocal referrals were rare. The study reveals distinct dynamics among providers in rural Uganda, with historical colonial influences continuing to shape relationships and highlighting the need for integrated, contextually appropriate mental healthcare systems.
Long-term birth cohorts are essential for studying health and disease over the life course. The retention of participants remains a challenge in study design. Previous research works on attrition are limited in length of follow-up time and lack of racial/ethnic diversity. Using data from the Wayne County Health, Environment, Allergy, and Asthma Longitudinal Study (WHEALS; United States cohort born between 2004 and 2007, n = 1258), we first performed longitudinal latent class analyses to identify patterns of participation spanning the prenatal period and six follow-up timepoints: 1, 6, 12, and 24 months; 3–6 years; and 10–12 years. Data collection included a combination of in-person visits, home visits, home specimen kits, and staff-administered questionnaires. We examined associations between baseline factors and participation class using multinomial logistic regression modeling, and with conditional inference modeling to identify variables most strongly associated with class. We identified four participation classes: high early participation with gradual loss-to-follow-up, sporadic participation, consistently high participation, and consistently low participation. Multiple baseline characteristics were associated with participation class. The “consistently high participation” class was disproportionately composed of participants who were older, were of higher education, had private insurance, had suburban residence, and were with higher income. Conditional inference trees identified maternal education, insurance, and income as most strongly associated with participation class. Through latent class modeling, we show that participants who were lost to follow-up fell into distinct groupings of participation. In the future, preparatory communications with those who are at the highest risk of study discontinuation may improve long-term retention.
Depressive disorders are the most common diagnosis among individuals who die by suicide, and intermittent theta-burst stimulation (iTBS) is a noninvasive treatment for those with difficult-to-treat depression who are at higher risk for suicide. Previous data suggests that pairing iTBS with D-cycloserine, a partial N-methyl-D-aspartate (NMDA) receptor agonist, improves antidepressant outcomes. However, its impact on suicide risk is not known.
Methods
We examine suicidal ideation and implicit suicide risk after iTBS+D-cycloserine in two clinical trials (open-label trial [n = 12] and randomized placebo-controlled trial [RCT, n = 50]) involving adults with major depressive disorder and the acute effects of D-cycloserine on implicit suicide risk in a crossover trial (n = 18). Implicit suicide risk was assessed using the computerized death/suicide implicit association test (IAT), and depressive symptoms and suicidal ideation were assessed using the clinician-rated Montgomery–Asberg Depression Rating Scale (MADRS).
Results
Open-label iTBS+D-cycloserine was associated with a rapid reduction in suicidal ideation, and iTBS+D-cycloserine was superior to iTBS+placebo in reducing suicidal ideation. Similarly, open-label iTBS+D-cycloserine was associated with decreased implicit suicide risk as measured by the death/suicide IAT, and iTBS+D-cycloserine was associated with greater decreases in death/suicide IAT scores compared to iTBS+placebo. A single acute dose of D-cycloserine in the absence of iTBS had no effect on implicit suicide risk.
Conclusions
Adjunctive D-cycloserine with iTBS is a promising strategy to reduce suicidal ideation and implicit suicide risk in depression.
Previous studies have linked social behaviors to COVID-19 risk in the general population. The impact of these behaviors among healthcare personnel, who face higher workplace exposure risks and possess greater prevention awareness, remains less explored.
Design:
We conducted a Prospective cohort study from December 2021 to May 2022, using monthly surveys. Exposures included (1) a composite of nine common social activities in the past month and (2) similarity of social behavior compared to pre-pandemic. Outcomes included self-reported SARS-CoV-2 infection (primary)and testing for SARS-CoV-2 (secondary). Mixed-effect logistic regression assessed the association between social behavior and outcomes, adjusting for baseline and time-dependent covariates. To account for missed surveys, we employed inverse probability-of-censoring weighting with a propensity score approach.
Setting:
An academic healthcare system.
Participants:
Healthcare personnel.
Results:
Of 1,302 healthcare personnel who completed ≥2 surveys, 244 reported ≥1 positive test during the study, resulting in a cumulative incidence of 19%. More social activities in the past month and social behavior similar to pre-pandemic levels were associated with increased likelihood of SARS-CoV-2 infection (recent social activity composite: OR = 1.11, 95% CI 1.02–1.21; pre-pandemic social similarity: OR = 1.14, 95% CI 1.07–1.21). Neither was significantly associated with testing for SARS-CoV-2.
Conclusions:
Healthcare personnel social behavior outside work was associated with a higher risk for COVID-19. To protect the hospital workforce, risk mitigation strategies for healthcare personnel should focus on both the community and workplace.
Recent theories have implicated inflammatory biology in the development of psychopathology and maladaptive behaviors in adolescence, including suicidal thoughts and behaviors (STB). Examining specific biological markers related to inflammation is thus warranted to better understand risk for STB in adolescents, for whom suicide is a leading cause of death.
Method:
Participants were 211 adolescent females (ages 9–14 years; Mage = 11.8 years, SD = 1.8 years) at increased risk for STB. This study examined the prospective association between basal levels of inflammatory gene expression (average of 15 proinflammatory mRNA transcripts) and subsequent risk for suicidal ideation and suicidal behavior over a 12-month follow-up period.
Results:
Controlling for past levels of STB, greater proinflammatory gene expression was associated with prospective risk for STB in these youth. Similar effects were observed for CD14 mRNA level, a marker of monocyte abundance within the blood sample. Sensitivity analyses controlling for other relevant covariates, including history of trauma, depressive symptoms, and STB prior to data collection, yielded similar patterns of results.
Conclusions:
Upregulated inflammatory signaling in the immune system is prospectively associated with STB among at-risk adolescent females, even after controlling for history of trauma, depressive symptoms, and STB prior to data collection. Additional research is needed to identify the sources of inflammatory up-regulation in adolescents (e.g., stress psychobiology, physiological development, microbial exposures) and strategies for mitigating such effects to reduce STB.
In the study of human dynamics, the behavior under study is often operationalized by tallying the frequencies and intensities of a collection of lower-order processes. For instance, the higher-order construct of negative affect may be indicated by the occurrence of crying, frowning, and other verbal and nonverbal expressions of distress, fear, anger, and other negative feelings. However, because of idiosyncratic differences in how negative affect is expressed, some of the lower-order processes may be characterized by sparse occurrences in some individuals. To aid the recovery of the true dynamics of a system in cases where there may be an inflation of such “zero responses,” we propose adding a regime (unobserved phase) of “non-occurrence” to a bivariate Ornstein–Uhlenbeck (OU) model to account for the high instances of non-occurrence in some individuals while simultaneously allowing for multivariate dynamic representation of the processes of interest under nonzero responses. The transition between the occurrence (i.e., active) and non-occurrence (i.e., inactive) regimes is represented using a novel latent Markovian transition model with dependencies on latent variables and person-specific covariates to account for inter-individual heterogeneity of the processes. Bayesian estimation and inference are based on Markov chain Monte Carlo algorithms implemented using the JAGS software. We demonstrate the utility of the proposed zero-inflated regime-switching OU model to a study of young children’s self-regulation at 36 and 48 months.
Persistent discrimination and identity threats contribute to adverse health outcomes in minoritized groups, mediated by both structural racism and physiological stress responses.
Objective:
This study aims to evaluate the feasibility of recruiting African American volunteers for a pilot study of race-based stress, the acceptability of a mindfulness intervention designed to reduce racism-induced stress, and to evaluate preliminary associations between race-based stress and clinical, psychosocial, and biological measures.
Methods:
A convenience sample of African Americans aged 18–50 from New York City’s Tri-state area underwent assessments for racial discrimination using the Everyday Discrimination Scale (EDS) and Race-Based Traumatic Stress Symptom Scale. Mental health was evaluated using validated clinical scales measuring depression, anxiety, stress, resilience, mindfulness, resilience, sleep, interpersonal connection, and coping. Biomarkers were assessed through clinical laboratory tests, allostatic load assessment, and blood gene expression analysis.
Results:
Twenty participants (12 females, 8 males) completed assessments after consent. Elevated EDS scores were associated with adverse lipid profiles, including higher cholesterol/high-density lipoprotein (HDL) ratios and lower HDL levels, as well as elevated inflammatory markers (NF-kB activity) and reduced antiviral response (interferon response factor). Those with high EDS reported poorer sleep, increased substance use, and lower resilience. Mindfulness was positively associated with coping and resilience but inversely to sleep disturbance. 90% showed interest in a mindfulness intervention targeting racism-induced stress.
Conclusions:
This study demonstrated an association between discrimination and adverse health effects among African Americans. These findings lay the groundwork for further research to explore the efficacy of mindfulness and other interventions on populations experiencing discrimination.
Recent approaches to heritage languages have sought to identify explanations for variability in heritage grammars. The present study explores variable patterns of Spanish differential object marking (DOM) in 40 heritage Spanish speakers (HSs) from the United States and 28 Spanish-dominant bilingual speakers (SDSs) from Mexico. Participants completed a picture description task including human, animal and inanimate direct objects. Both groups exhibited patterns of DOM following the Animacy Scale. However, HSs showed lower DOM rates and greater individual variability with human referents compared to SDSs, even when individual differences in language dominance were considered. Conversely, SDSs produced lower rates of DOM with inanimate objects than HSs. DOM use was constrained by verb-specific animacy biases across animacy conditions and speaker groups. These findings reveal that Spanish HSs maintain baseline-like variable patterns of DOM. Moreover, HSs may advance language change in predictable directions based on patterns of variation present in the baseline variety.
Translational science rarely addresses the needs of rural communities, perpetuating health inequities. Furthermore, policy and resource allocation reflect this dynamic. Through a partnership between a rural community and a community engagement program, the Rural Health Initiative (RHI) was developed with the goal of building capacity for community-driven translational research in rural settings.
Methods:
We describe the process of forming the RHI and selection of a community health priority to motivate the translational research agenda in this particular rural setting. We used a mixed methods approach utilizing literature review, community survey data, and qualitative evaluation of community meeting discussions. Consensus on a final health priority was built through voting and comparison of voting responses across the three RHI counties through Fisher’s Exact test.
Results:
Four priority topics were identified through literature search, community needs assessment, state/national trend data, and community experts. Priority ranking from a community forum and survey selected the final health priority topic. Healthcare access was selected by all three counties in the RHI community as the most critical health priority to address.
Conclusions:
This program highlights the importance of and methods for community involvement in directing the research conducted in their community. Additionally, through this project, guidance was developed to define the role of community engagement programs supporting work led by communities.
In honor of the 100th anniversary of the Federal Arbitration Act, this volume brings together a diverse group of leading scholars and practitioners to celebrate its successes and propose specific reforms. Readers will gain insight into how the Federal Arbitration Act impacts the modern practice of arbitration and how the Supreme Court’s interpretation of the Act undermines its fairness. Focusing on domestic, commercial and consumer, as well as securities and labor and employment arbitration, this book provides a roadmap to enhance the fairness and coherence of the Act. The volume is unique in that it serves as the impetus for a law reform project, with over thirty scholars speaking collectively for improvements to the law. More effective than scattershot arguments, this coordinated effort delivers a consistent message to a national audience: that arbitration has become ubiquitous and the law should ensure it is fair and equitable.
