A secreted sirtuin from Campylobacter jejuni contributes to neutrophil activation and intestinal inflammation during infection.

Histone modifications control numerous processes in eukaryotes, including inflammation. Some bacterial pathogens alter the activity or expression of host-derived factors, including sirtuins, to modify histones and induce responses that promote infection. In this study, we identified a deacetylase encoded by Campylobacter jejuni which has sirtuin activities and contributes to activation of human neutrophils by the pathogen. This sirtuin is secreted from the bacterium into neutrophils, where it associates with and deacetylates host histones to promote neutrophil activation and extracellular trap production. Using the murine model of campylobacteriosis, we found that a mutant of this bacterial sirtuin efficiently colonized the gastrointestinal tract but was unable to induce cytokine production, gastrointestinal inflammation, and tissue pathology. In conclusion, these results suggest that secreted bacterial sirtuins represent a previously unreported class of bacterial effector and that bacterial-mediated modification of host histones is responsible for the inflammation and pathology that occurs during campylobacteriosis.

Involuntary Civil Commitment for Substance Use Disorders in Puerto Rico: Neglected Rights Violations and Implications for Legal Reform.

Laws facilitating the involuntary civil commitment (ICC) of people with substance use disorders vary considerably internationally and across the United States. Puerto Rico, a colonial territory of the United States since 1898, currently harbors the most punitive ICC legislation in the country. It is the only place in the United States where self-sufficient adults who pose no grave danger to themselves or others can be involuntarily committed to restrictive residential facilities for over a year at a time without ever being assessed by a health care professional. The involuntary commitment of otherwise-able citizens-many of whom have never been diagnosed with a substance use disorder-continues to be ignored nationally and internationally. In this paper, we specify how Puerto Rican ICC law and procedures systematically violate rights and liberties that are supposed to be guaranteed by Puerto Rico's Mental Health Act, the US Federal Supreme Court, and the Universal Declaration of Human Rights. To ensure that Puerto Rico's ICC procedures conform to prevailing local, national, and international standards, we propose a series of legislative reforms. Finally, we highlight the importance of addressing the preponderance of poorly constructed ICC laws both within the United States and internationally.

Vocal Function Differences Before and After Sorority Recruitment.

PURPOSE: Participation in sorority recruitment often results in acute vocal impairment. The purpose of this investigation was to characterize the extent to which voice function and laryngeal appearance may be altered by participation in this social phenomenon. METHODS: Using a within-participant repeated measures design, nine women participating as sorority recruiters completed the study protocol. The following data were collected at two time points, immediately before and after the completion of two weeks of sorority recruitment: stroboscopic laryngeal imaging, vocal acoustic measures, and perceptual measures of vocal effort and voice quality. RESULTS: Perceived phonatory effort and overall severity of voice quality were significantly impaired following sorority recruitment. All participants had evidence of mucosal changes in the form of one or more the following: observed edema, erythema, increased vascularity, glottic margin changes. No significant differences in acoustic measures were identified. CONCLUSIONS: Increased perceived vocal effort, increased overall severity ratings of voice quality, and deleterious vocal fold tissue changes observed support the hypothesis that the acute vocal loading that is characteristic of the sorority recruitment process contributes to a decline in voice function in the short term. Acoustic measures taken either lacked the sensitivity for the perceived decline in voice function or the participants, who were otherwise healthy, managed to adapt the acoustic signal to the tissue changes observed. The extent to which these acute changes may be mitigated with vocal hygiene and voice training is an area for future study.

Substance use policy and practice in the COVID-19 pandemic: Learning from early pandemic responses through internationally comparative field data.

The COVID-19 pandemic has created an unprecedented natural experiment in drug policy, treatment delivery, and harm reduction strategies by exposing wide variation in public health infrastructures and social safety nets around the world. Using qualitative data including ethnographic methods, questionnaires, and semi-structured interviews with people who use drugs (PWUD) and Delphi-method with experts from field sites spanning 13 different countries, this paper compares national responses to substance use during the first wave of the COVID-19 pandemic. Field data was collected by the Substance Use x COVID-19 (SU x COVID) Data Collaborative, an international network of social scientists, public health scientists, and community health practitioners convened to identify and contextualise health service delivery models and social protections that influence the health and wellbeing of PWUD during COVID-19. Findings suggest that countries with stronger social welfare systems pre-COVID introduced durable interventions targeting structural drivers of health. Countries with fragmented social service infrastructures implemented temporary initiatives for PWUD led by non-governmental organisations. The paper summarises the most successful early pandemic responses seen across countries and ends by calling for greater systemic investments in social protections for PWUD, diversion away from criminal-legal systems toward health interventions, and integrated harm reduction, treatment and recovery supports for PWUD.

College-Based Transition Services' Impact on Self-Determination for Youth With Intellectual and Developmental Disabilities.

Most youth in transition services with labels of intellectual and developmental disabilities (IDD) have poorer employment outcomes than their peers with other or without disabilities. One alternative approach to address this challenge provides youth with IDD access to transition services in the context of a college or university campus. College-based transition services (CBTS) provide students with IDD access to college courses, internships, and employment during their final 2 to 3 years of secondary education. A quasi-experimental design evaluation of one college-based transition services model, Think College Transition, found that, after controlling for student baseline scores, the college-based transition services had a significant effect on students' scores of self-determination at post-test. Implications for further refining the model are discussed.

Categorical dilemmas: challenges for HIV prevention among men who have sex with men and transgender women in Vietnam.

In Vietnam, HIV continues disproportionately to affect men who have sex with men and transgender women, and the increase in HIV prevalence in these populations may be related to a lack of tailoring of current prevention approaches, which often fail to address social diversity within these populations. To effectively respond to HIV in Vietnam, it is imperative to identify sub-populations within the broad category of 'men who have sex with men' (MSM), a term which in Vietnam as in many other sites frequently subsumes transgender women. In this paper, we document the different categories used to describe people who engage in same-sex sexual practices and/or non-normative gender performances drawing on data collected via in-depth interviews and focus groups with a total of 79 participants in Hanoi. We identified over 40 different categories used to describe men who have sex with men and/or transgender women. These categories could be described as behaviourally-based, identity-based, or emic, and each carried different meanings, uses (based on age and geography) and levels of stigma. The categories shine light on the complexity of identities among men who have sex with men and transgender women and have utility for future research and programming to more comprehensively address HIV in Vietnam.

From Treatment to Containment to Enterprise: An Ethno-history of Therapeutic Communities in Puerto Rico, 1961-1993.

Unpaid work is now a central therapy in Puerto Rican therapeutic communities, where substance users reside and seek to rehabilitate each other, often for years at a time. Once a leading treatment for addiction in mainland United States, therapeutic communities were scaled back in the 1970s after they lost federal endorsement. They continue to flourish in Puerto Rico for reasons that have less to do with their curative powers than with their malleability as multi-purpose social enterprises and their historical co-option by state, market and family actors who have deployed them for a variety of purposes. Their endurance from the 1960s to the neoliberal present obliges us to recognize their capacities as what Mizruchi calls abeyance mechanisms whereby 'surplus' populations, otherwise excluded from labor and home, are absorbed into substitute livelihoods. Having initially emerged as a low-cost treatment, in a context of mass unemployment and prison-overcrowding they now thrive as institutions of containment and informal enterprise.

An institutional ethnography of prevention and treatment services for substance use disorders in the Dominican Republic.

The Dominican Republic is thought to have significant epidemics of illicit drug use but lacks surveillance and formal analyses of the policy context of drug prevention and treatment services. We conducted an institutional ethnography of 15 drug service organisations in Santo Domingo and Boca Chica, Dominican Republic, to explore barriers and resources for drug abuse prevention and treatment. Here, we present a typology of drug service organisations based on their services, methods, and approach. We then draw on interviews with representatives of drug service institutions to describe the primary barriers to drug treatment and prevention services for drug users. We conclude with a focus on the policy priorities that could improve the conditions of health care for marginalised drug users in the Dominican Republic.

Pharmacodynamic Effects of Pioglitazone on High Molecular Weight Adiponectin Concentrations and Insulin Response After Oral Sugar in Equids.

Chronic insulin dysregulation is challenging to manage with pharmaceuticals in horses. Pioglitazone improves insulin sensitivity in humans, and the pharmacokinetics of pioglitazone have been evaluated in horses. The objectives of this study were to assess the pharmacodynamic effects of oral pioglitazone on morphometric parameters, hepatic enzyme activity and function, adipokines, and enteroinsular response to oral sugar. A prospective pilot study was performed using fifteen adult equids (8 ponies, 7 horses) to evaluate the effects of short-term pioglitazone administration (2 mg/kg PO q 24 hours, 28 days). Oral sugar tests (OST) were performed before and after treatment. Adipokines were measured at day 0, 14, and 28 of administration. Plasma drug concentrations were measured at day 14 and 28 of administration. The subjects were grouped into horses, ponies, and insulin dysregulated (ID) animals. Baseline values for all parameters were compared with values obtained at day 14 and 28 using one-way or two-way analysis of variance. Mild changes were noted in morphometric parameters and hepatic enzymes. No differences were found in leptin concentrations or the blood glucose response to the OST. Significant decreases were found in the insulin response to OST at 90 and 120 minutes time points and the area under the curve after pioglitazone treatment in the pony and ID groups. High-molecular-weight (HMW) adiponectin concentrations were significantly increased in all groups after pioglitazone treatment. Decreased insulin concentrations in response to oral sugar and increased HMW adiponectin concentrations indicate positive effects of pioglitazone for treatment of metabolic derangements in equine metabolic syndrome, which warrant future clinical study.

Public Libraries: A Community-Level Resource to Advance Population Health.

Policy makers and public health practitioners rarely consider public libraries to be part of the health system, even though they possess several characteristics that suggest unrealized potential to advance population health. This scoping review uses an adapted social determinants framework to categorize current health-related work conducted by public libraries in the United States and to discuss libraries' potential as 'meso-level' community resources to improve population health. Our discussion of libraries contributes to scholarship on place-based health disparities, by emphasizing the potential impact of institutions that are modifiable through social policy-e.g., parks, community centers, schools-and which have a conceptually clear or empirically documented relationship to health.

The Urgent Need for Research and Interventions to Address Family-Based Stigma and Discrimination Against Lesbian, Gay, Bisexual, Transgender, and Queer Youth.

PURPOSE: This scoping study sought to provide an overview of existing interventions, programs and policies that address family-based stigma and discrimination against LGBTQ youth. METHODS: A keyword search in three online databases identified relevant scientific publications. Because it located a relatively small number of peer-reviewed publications, additional grey literature references were included, identified through consultation with specialists and through anonymous peer-review. Research, policies and interventions were categorized using an adapted ecological framework. RESULTS: There is very little peer-reviewed research on interventions to reduce family stigma and discrimination against LGBTQ youth. Most on-going work to improve family environments for LGBTQ youth appears to be currently conducted by city governments and non-governmental organizations. Very few interventions or programs provide any outcome data. Theoretical frameworks and approaches vary widely. CONCLUSIONS: Given the widely recognized importance of a supportive family environment for a healthy transition to adulthood for LGBTQ youth, there is an urgent need for scientific research on policies and interventions to address stigma and discrimination and create supportive environments within families. Tackling family-based stigma and discrimination will require interventions and policies at each level of the ecological framework, including individual- and interpersonal-level interventions as well as community-level programs and structural-level policymaking.

Joint BAP NAPICU evidence-based consensus guidelines for the clinical management of acute disturbance: De-escalation and rapid tranquillisation.

The British Association for Psychopharmacology and the National Association of Psychiatric Intensive Care and Low Secure Units developed this joint evidence-based consensus guideline for the clinical management of acute disturbance. It includes recommendations for clinical practice and an algorithm to guide treatment by healthcare professionals with various options outlined according to their route of administration and category of evidence. Fundamental overarching principles are included and highlight the importance of treating the underlying disorder. There is a focus on three key interventions: de-escalation, pharmacological interventions pre-rapid tranquillisation and rapid tranquillisation (intramuscular and intravenous). Most of the evidence reviewed relates to emergency psychiatric care or acute psychiatric adult inpatient care, although we also sought evidence relevant to other common clinical settings including the general acute hospital and forensic psychiatry. We conclude that the variety of options available for the management of acute disturbance goes beyond the standard choices of lorazepam, haloperidol and promethazine and includes oral-inhaled loxapine, buccal midazolam, as well as a number of oral antipsychotics in addition to parenteral options of intramuscular aripiprazole, intramuscular droperidol and intramuscular olanzapine. Intravenous options, for settings where resuscitation equipment and trained staff are available to manage medical emergencies, are also included.

Gendered Social Institutions and Preventive Healthcare Seeking for Black Men Who Have Sex with Men: The Promise of Biomedical HIV Prevention.

Research on gender and health, including research conducted among Black men who have sex with men (BMSM), has primarily focused on how gender norms and roles shape healthcare engagement. Here we advance that work by demonstrating how a broader theorization of gender, particularly one that moves beyond gender norms and performance to incorporate structures such as the healthcare system and the labor market, can facilitate an understanding of how gender affects preventive healthcare seeking among BMSM, particularly the uptake of pre-exposure prophylaxis (PrEP), a promising approach to alleviate HIV disparities. This article is based on a year-long ethnographic study conducted in New York City with BMSM (n = 31; three interviews each) and community stakeholders (n = 17). Two primary findings emerged: (1) the labor market systematically excluded the men in our sample, which limited their ability to access employer-sponsored healthcare. Such discrimination may promote overt demonstrations of masculinity that increase their HIV vulnerability and decrease healthcare seeking, and (2) healthcare systems are not structured to promote preventive healthcare for men, particularly BMSM. In fact, they constrained men's access to primary providers and were usually tailored to women. Applying a structural, gendered lens to men's health-in addition to the more frequently researched individual or interpersonal levels-provides insight into factors that affect healthcare seeking and HIV prevention for BMSM. These findings have implications for the design of policies and institutional reforms that could enhance the impact of PrEP among BMSM. Findings are also relevant to the management of chronic disease among men more broadly.

Tourism Labor, Embodied Suffering, and the Deportation Regime in the Dominican Republic.

In this article, we use syndemic theory to examine socio-structural factors that result in heightened vulnerability to HIV infection and drug addiction among Dominican deportees who survive post-deportation through informal tourism labor. Through an ongoing NIDA-funded ethnographic study of the syndemic of HIV and problematic drug use among men involved in tourism labor in the Dominican Republic, we argue that the legal and political-economic context of the global deportation regime contributes to structural vulnerabilities among deportees in the Dominican Republic, most of whom are men with histories of incarceration in the United States and/or Puerto Rico. While Dominican laws and institutional practices work conjointly with foreign policies to reconfigure non-criminal deportees as hardened criminals unworthy of full citizenship rights, the informal tourism economy provides one of the few absorption points for male deportee labor, linking the deportation regime directly to the Caribbean tourism industry.

The Impact of Urban US Policing Practices on Black Men Who Have Sex with Men's HIV Vulnerability: Ethnographic Findings and a Conceptual Model for Future Research.

This paper advances research on racism and health by presenting a conceptual model that delineates pathways linking policing practices to HIV vulnerability among Black men who have sex with men in the urban USA. Pathways include perceived discrimination based on race, sexuality and gender performance, mental health, and condom-carrying behaviors. The model, intended to stimulate future empirical work, is based on a review of the literature and on ethnographic data collected in 2014 in New York City. This paper contributes to a growing body of work that examines policing practices as drivers of racial health disparities extending far beyond violence-related deaths.

Implementing guidelines on physical health in the acute mental health setting: a quality improvement approach.

BACKGROUND: In the UK, life expectancy for people living with a serious mental illness, such as schizophrenia and bipolar disorder, is reduced by 15-20 years compared with the general population. In recent years, evidence based guidelines/policies designed to improve their physical health have been published, yet a gap remains between recommendations and practice. This case study describes how guidelines to support physical health were implemented using a quality improvement approach. CASE PRESENTATION: A quasi-experimental study explored systems and processes for assessing the physical health of patients admitted to an acute mental health unit. The multi-disciplinary team of healthcare professionals, service users and experts in quality improvement methods developed solutions to improve the assessment of physical health, drawing on existing guidelines/policies as well as professional and lived experience. Three key interventions were developed: a comprehensive physical health assessment; a patient-held physical health booklet; and education and training for staff and patients. Interventions were co-designed by front-line healthcare staff and service users with iterative development and implementation through Plan-Do-Study-Act cycles. Real-time weekly data were reported on five measures over a 15-month implementation period (318 patients) and compared to a 10-month baseline period (247 patients) to gauge the success of the implementation of the physical health assessment. Improvements were seen in the numbers of patients receiving a physical health assessment: 81.3% (201/247) vs 96.9% (308/318), recording of body mass index: 21.55% (53/247) vs 58.6% (204/318) and systolic blood pressure: 22.35% (55/247) vs 75.9% (239/318) but a reduction in the recording of smoking status: 80.1% (198/247) vs 70.9% (225/318). However, 31.7% (118/318) patients had a cardiovascular risk-score documented in the implementation phase, compared to none in the baseline. CONCLUSION: This study demonstrates the use of a quality improvement approach to support teams to implement guidelines on physical health in the acute mental health setting. Reflections of the team have identified the need for resources, training, support and leadership to support changes to the way care is delivered. Furthermore, collaborations between service users and frontline clinical staff can co-design interventions to support improvements and raise awareness of the physical health needs of this population.

Social risk, stigma and space: key concepts for understanding HIV vulnerability among black men who have sex with men in New York City.

Black men who have sex with men in the USA face disproportionate incidence rates of HIV. This paper presents findings from an ethnographic study conducted in New York City that explored the structural and socio-cultural factors shaping men's sexual relationships with the goal of furthering understandings of their HIV-related vulnerability. Methods included participant observation and in-depth interviews with 31 Black men who have sex with men (three times each) and 17 key informants. We found that HIV vulnerability is perceived as produced through structural inequalities including economic insecurity, housing instability, and stigma and discrimination. The theoretical concepts of social risk, intersectional stigma, and the social production of space are offered as lenses through which to analyse how structural inequalities shape HIV vulnerability. We found that social risk shaped HIV vulnerability by influencing men's decisions in four domains: 1) where to find sexual partners, 2) where to engage in sexual relationships, 3) what kinds of relationships to seek, and 4) whether to carry and to use condoms. Advancing conceptualisations of social risk, we show that intersectional stigma and the social production of space are key processes through which social risk generates HIV vulnerability among Black men who have sex with men.

Prescribing clozapine and rifampicin: clinical impact of their interaction.

The predictable pharmacokinetic drug interaction between clozapine and rifampicin is listed in most standard reference texts but little detail is given or emphasis on its clinical significance. The interaction is based on theoretical knowledge of both drugs; to date just two case reports have been published. This article describes a third case demonstrating the significance of this interaction. This was potentially devastating for the patient who required an extended psychiatric admission. The enzyme induction was so potent that the dose of clozapine had to be increased approximately sixfold. Careful management of this significant interaction is essential for effective patient care.

The Promise of Pre-Exposure Prophylaxis for Black Men Who Have Sex with Men: An Ecological Approach to Attitudes, Beliefs, and Barriers.

Research has demonstrated the clinical effectiveness of pre-exposure prophylaxis (PrEP) for HIV prevention, but little is known about how factors at the individual-, interpersonal-, community-, and structural levels impact PrEP use for black men who have sex with men (BMSM). We advance existing work by examining how all levels of the ecological framework must be addressed for PrEP to be successfully implemented as an effective HIV prevention approach. We interviewed 31 BMSM three times each and 17 community stakeholders once each; interviews were taped, transcribed, and analyzed using the constant comparative method. Factors that influence how BMSM experienced PrEP emerged across all levels of the ecological framework: At the individual level, respondents were wary of giving medication to healthy people and of the potential side-effects. At the interpersonal level, BMSM believed that PrEP use would discourage condom use and that PrEP should only be one option for HIV prevention, not the main option. At the community level, men described not trusting the pharmaceutical industry and described PrEP as an option for others, not for themselves. At the structural level, BMSM talked about HIV and sexuality-related stigmas and how they must overcome those before PrEP engagement. BMSM are a key population in the US National HIV/AIDS Strategy, yet few individuals believe that PrEP would be personally helpful. Our research indicates the urgent need to raise awareness and address structural stigma and policies that could be substantial barriers to the scale-up and implementation of PrEP-related services.
