HIV and intersectional stigma among people living with HIV and healthcare workers and antiretroviral therapy adherence in the Dominican Republic.

BACKGROUND: HIV-related stigma, discrimination, and social marginalization undermines optimal HIV care outcomes. More research examining the impact of HIV-related stigma, discrimination, other interlocking forms of oppression, and antiretroviral therapy (ART) adherence is needed to optimize HIV treatment programming. This study uses data from two clinics in the Dominican Republic to examine client and healthcare worker (HCW) perceptions of HIV and intersectional stigmas among people living with HIV. METHODS: Surveys exploring demographics, HIV-related stigma, various dimensions of discrimination (race/ethnicity, HIV status, sexual orientation), healthcare engagement, and medication adherence were collected from 148 clients and 131 HCWs. Analysis of variance was conducted to examine differences in stigma by clinic and logistic regressions were used to determine predictors of optimal client medication adherence. RESULTS: Perceived discrimination in healthcare facilities due to clients' sexual orientation retained significance in crude and multivariable logistic regression models and was negatively associated with ART adherence (aOR:0.79; 95% CI:0.66, 0.95). DISCUSSION: Findings highlight the importance of implementing strategies to address stigma, discrimination, and social marginalization, particularly within healthcare facilities.

"They think we wear loincloths": Spatial stigma, coloniality, and physician migration in Puerto Rico.

Puerto Rico (PR) is facing an unprecedented healthcare crisis due to accelerating migration of physicians to the mainland United States (US), leaving residents with diminishing healthcare and excessively long provider wait times. While scholars and journalists have identified economic factors driving physician migration, our study analyzes the effects of spatial stigma within the broader context of coloniality as unexamined dimensions of physician loss. Drawing on 50 semi-structured interviews with physicians throughout PR and the US, we identified how stigmatizing meanings are attached to PR, its people, and its biomedical system, often incorporating colonial notions of the island's presumed backwardness, lagging medical technology, and lack of cutting-edge career opportunities. We conclude that in addition to economically motivated policies, efforts to curb physician migration should also address globally circulating ideas about PR, acknowledge their roots in coloniality, and valorize local responses to the crisis that are in danger of being lost to history.

On leaving: Coloniality and physician migration in Puerto Rico.

Puerto Rico (PR) has a growing physician migration problem. As of 2009, the medical workforce was composed of 14,500 physicians and by 2020 the number had been reduced to 9,000. If this migration pattern continues, the Island will not be able to meet the recommended physicians per capita ratio proposed by the World Health Organization (WHO). Existing research has focused on the personal motivations for movement to, or permanence in, a particular setting, and social variables that encourage physicians to migrate (e.g., economic conditions). Few studies have addressed the role of coloniality in fostering physician migration. In this article we examine the role of coloniality and its impact on PR's physician migration problem. The data presented in this paper stem from an NIH-funded study (1R01MD014188) that aimed to document the factors associated with physician migration from PR to the US mainland and its impact on the Island's healthcare system. The research team used qualitative interviews, surveys, and ethnographic observations. This paper focuses on the data from the qualitative interviews with 26 physicians who had migrated to the USA and ethnographic observations, which were collected and analyzed between September 2020 and December 2022. The results evidence that participants understand physician migration as a consequence of three factors: 1) the historical and multidimensional deterioration of PR, 2) the idea that the current healthcare system is rigged by politicians and insurance companies, and 3) the specific challenges faced by physicians in training on the Island. We discuss the role of coloniality in fostering these factors and how it serves as the backdrop for the problem faced by the Island.

Multilevel barriers to using assistive technology devices among older hispanics from poor and disadvantaged communities: the relevance of a gender analysis.

PURPOSE: To get a rich description of the barriers to using assistive technology (AT) among men and women ≥65 years living in poor and disadvantaged communities in Puerto Rico, an issue not well described among older people. METHODS: We conducted qualitative interviews assisted by videos of AT and guided by the Matching Person and Technology Model and the Gender Analysis Framework with a purposive sample of 23 men and women. Participants were asked questions regarding reasons for not using AT, willingness for using AT, their identified gender roles and gender-related activities, and bargaining positions. They were also asked about their access to resources to acquire AT, bargaining positions, the stigma associated with AT use, and the characteristics of AT. Directed content analysis with input from a Community Advisory Board was used for the interpretation of the results. RESULTS: The predominant barrier (for both men and women) to using AT devices were: lack of information about AT s and access to money for their purchase, lack of availability and cost of such devices, and (self)-stigma. More women than men experienced limited access to AT services, limited access to and control of money, limited skills for using AT, and less bargaining power for making independent decisions. More men than women expressed a lack of functional need and personal preferences other than using AT devices for managing difficulties in activities. CONCLUSION: There are gender differences concerning the multilevel barriers to using AT devices among older Hispanics residing in low-income communities.IMPLICATIONS FOR REHABILITATIONOlder Hispanic men and women in this study experienced different obstacles to using assistive technology (AT) they need for compensating their functional disabilities in daily living activities.Women in this study reported having less access to money and AT services, diminished skills for using AT devices, and less power to make independent decisions to access AT devices compared to men.To ensure the equitable provision of AT, cultural as well as gender-related factors concerning AT use need to be considered.Future research should focus on women's functional health, also should focus on the development of gender-sensitive and culturally competent AT interventions to improve older Hispanics from poor communities function and opportunities for ageing at their homes and in their communities.

Adapting and pilot testing an HIV and intersectional stigma reducing intervention for Dominican Republic healthcare contexts: Protocol for translational research.

Background: This protocol details the adaptation and pilot testing of the Finding Respect and Ending Stigma around HIV (FRESH) intervention in Dominican Republic. FRESH is a healthcare setting stigma-reduction intervention designed to reduce stigmas affecting people living with HIV (PLHIV), focusing on HIV and intersectional stigmas experienced by sexual and gender minority (SGM) people living with HIV. After the successful adaptation of the FRESH intervention, it will be pilot-tested through the conduct of a pilot stepped wedge cluster randomized controlled trial. Methods: Three aims are included in this study; Aim 1 includes exploratory qualitative assessment, specifically the conduct four focus groups with men who have sex with men (MSM) living with HIV (n = 24-32) and in-depth interviews with transgender women living with HIV to explore their experiences with stigma in clinics (n = 9-12). In-depth interviews will also be held with HIV healthcare workers to elucidate their perceptions and behaviors towards their SGM clients (n = 9-12). In Aim 2, informed by Aim 1 data, we will use the sequential phases of the ADAPT-ITT framework to iteratively adapt the FRESH intervention for the Dominican Republic. In Aim 3, the adapted intervention will be pilot-tested via a cluster stepped wedge randomized controlled trial to assess feasibility and acceptability of the intervention and study protocols. Conclusions: If this pilot trial is successful, next steps will include testing the adapted intervention across Dominican Republic or in similar Spanish-speaking Caribbean nations in a larger trial to assess effectiveness in reducing stigma in clinical settings towards PLHIV.

Red tape, slow emergency, and chronic disease management in post-María Puerto Rico.

This paper draws upon the notion of slow emergency as a framework to interpret ethnographic and qualitative findings on the challenges faced by Puerto Ricans with chronic conditions and health sector representatives throughout the island during and after Hurricane María. We conducted participant observation and qualitative interviews with chronic disease patients (n=20) health care providers and administrators (n=42), and policy makers (n=5) from across the island of Puerto Rico in 2018 and 2019. Many Puerto Ricans coping with chronic diseases during and after María experienced bureaucratic red tape as the manifestation of colonial legacies of disaster management and health care. They describe a precarious existence in perpetual "application pending" status, waiting for services that were not forthcoming. Drawing on ethnographically informed case examples, we discuss the effects of these bureaucratic barriers on persons with three chronic conditions: renal disease, opioid dependency, and HIV/AIDS. We argue that while emergency management approaches often presume a citizen-subject with autonomous capacity to prepare for presumably transient disasters and envision a 'post-disaster future' beyond the immediate crisis, Puerto Rican voices draw attention to the longer, sustained, slow emergency of colonial governance.

The impact of Hurricane Maria on Puerto Rico's health system: post-disaster perceptions and experiences of health care providers and administrators.

BACKGROUND: After its landfall in Puerto Rico in 2017, Hurricane Maria caused the longest blackout in United States history, producing cascading effects on a health care system that had already been weakened by decades of public sector austerity and neoliberal health reforms. This article addresses how health care professionals and administrators experienced the health care system's collapse and the strategies used by them to meet their communities' health needs. METHODS: Data were collected between September 2018 and February 2020. Ethnographic observations in health care facilities and semi-structured qualitative interviews with representatives of the health care system were conducted. This paper focuses on data from interviews with health care providers (n = 10) and administrators (n = 10), and an ethnographic visit to a pop-up community clinic. The analysis consisted of systematic thematic coding of the interview transcripts and ethnographic field notes. RESULTS: Results provide insight on how participants, who witnessed first-hand the collapse of Puerto Rico's health care system, responded to the crisis after Maria. The prolonged power outage and lack of a disaster management plan were partly responsible for the death of 3,052 individuals who experienced extended interruptions in access to medical care. Participants reported a sense of abandonment by the government and feelings of mistrust. They also described the health sector as chaotic and lacking clear guidelines on how to provide services or cope with personal crises while working under extreme conditions. In such circumstances, they developed resilient responses to meet communities' health needs (e.g., itinerant acupuncture services, re-locating physicians to local pharmacies). CONCLUSIONS: Participants' narratives emphasize that the management of Hurricane Maria was fraught with political and economic constraints affecting Puerto Rico. Ineffective planning and post-Maria responses of the local and federal governments were determinants of the disaster's impact. The findings contribute to a growing scientific literature indicating that Hurricane Maria revealed 'the collapse before the collapse,' alluding to the structural deficiencies that presaged the catastrophic event. In the context of governmental abandonment, the authors argue for the importance of developing alternative strategies in post-disaster health care provision among health professionals and administrators who work at the front lines of recovery.

Sex disparities in the prevalence of physical function disabilities: a population-based study in a low-income community.

BACKGROUND: Functional disability continues to be a significant public health problem that increases older adults' vulnerability to experience a diminished quality of life, loss of independence, higher healthcare costs and health services utilization, and increased risks of mortality. Thus, we aimed to study the prevalence of functional disabilities by sex according to the types of daily living activities, controlling for specific sociodemographic variables among older Hispanics from low-income communities. METHODS: We used a cross-sectional epidemiological research design, considering a complex sampling design of households to interview adults ≥65 years living in low-income communities in Puerto Rico. Functional disability was measured by the PROMIS® Physical Function Short Form-20 T-score. The selected community was reported to have 5980 adult residents ≥65 years, according to the USA Census. The prevalence of functional disability was estimated using the logistic regression model, weighting by the effect of the sampling. Our estimated prevalence was compared between sexes using the prevalence ratio (PR), which was estimated with logistic regression models, controlling for age, income, number of chronic conditions, high and low impact of chronic conditions in functional disabilities, marital status, and sampling design. RESULTS: We recruited 211 older Hispanics from a randomly selected sample. Their mean age was 74.4 ± 7.1 years, with female predominance (57.3%). The overall estimated prevalence of physical function disability using T-score among females was 2.70 (95% CI: 1.4, 5.1) times the estimated prevalence of physical function disability among males. Women were more likely to report functional disabilities in instrumental activities of daily living, self-care activities, and functional mobility compared to males. However, sex differences were largely explained by the presence of musculoskeletal conditions of high impact in functional disability. CONCLUSIONS: The females in our study bear the greater burden of physical function disability in their adult age. Health policies, as well as future studies, should be targeted at reducing the burden of physical function disabilities in different types of daily activities through gender-sensitive disability self-management programs.

Development and Validation of the Community PrEP-Related Stigma Scale (Community-PSS).

Despite increasing availability of pre-exposure prophylaxis (PrEP), HIV prevention efforts have stalled. It is important to study potential barriers to HIV prevention methods, such as pre-exposure prophylaxis stigma. This study aims to develop and validate the Community PrEP-related Stigma Scale (Community-PSS) to address gaps in the literature. Participants were 108 sexual and gender minority men recruited through virtual and community-posted advertisements in Florida. The authors assessed reliability using Cronbach's alpha analysis, determined scale components using principal component analysis, and assessed construct validity based on five a priori hypotheses. The scale had high internal consistency (α = 0.86) and four components (stigma of actions outside of sex, stigma of sexual actions, extreme stigma perceptions, and positive community perception). The Community-PSS was valid, supporting four out of five hypotheses and in the expected directions. The Community-PSS was a valid and reliable tool in the sample and correlates with a previously validated PrEP stigma scale, HIV knowledge, PrEP knowledge, and likelihood of condom use with a partner on PrEP.

Understanding the Multilevel Disability Self-Management Strategies of Puerto Rican Older Men.

Aims: To explore the person, environment, and occupation-related self-management strategies used by older Hispanic men to cope with disabilities in different types of daily activities. Methods: A concurrent transformative mixed method design (with priority given to the qualitative phase) guided by the Environment and Occupational Performance Model was used to collect and analyze data of 12 participants with functional disabilities. Quantitative data was gathered using the PROMIS Physical Function Short Form-20. Qualitative data was obtained from in-depth semi-structured interviews on participants' self-management strategies. Results: The average T-score (35.96) was below the national average. Participants reported higher levels of functional disabilities in instrumental activities of daily living (IADL), and predominantly used practical social support and change in method of performance to manage their difficulties in self-care, IADL, and functional mobility activities. Conclusions: These strategies may be used with similar populations to design interventions aimed at increasing older Puerto Rican's function.

Enacted HIV-Related Stigma's Association with Anxiety & Depression Among People Living with HIV (PLWH) in Florida.

Research has shown that HIV-related stigma contributes to people living with HIV having a higher risk of mental health disorders. Our study examines the association between enacted HIV-related stigma and symptoms of anxiety and depression among PLWH. We used baseline data from 932 PLWH collected from the Florida Cohort study between 2014 and 2018. The sample was majority 45 + years of age (63.5%), male (66.0%), and Black (58.1%). The majority had previously experienced enacted HIV-related stigma (53.1%). Additionally, 56.6% and 65.2% showed mild to moderate/severe levels of anxiety and depression, respectively. Those who experienced any levels of enacted HIV-related stigma (vs none) had significantly greater odds of mild and moderate/severe levels of anxiety (vs no/minimal) (AOR[CI] 1.54[1.13, 2.10], p = 0.006; AOR[CI] 3.36[2.14, 5.26], p < 0.001, respectively) and depression (AOR[CI] 1.61[1.19, 2.18], p = 0.002; AOR[CI] 3.66[2.32, 5.77], p < 0.001, respectively). Findings suggest a need to evaluate interventions for PLWH to reduce the deleterious effects of enacted HIV-related stigma on mental health.

RESUMEN: Investigaciones previas han documentado que el estigma relacionado con el VIH contribuye al alto riesgo de trastornos de salud mental entre las personas que viven con VIH. Nuestro estudio examina la asociación entre el estigma declarado y síntomas de ansiedad y depresión entre las personas que viven con VIH. Utilizamos datos de referencia recopilados por el "Florida Cohort Study" de 932 personas que viven con VIH. La mayoría de la muestra sobrepasaba 45 años (63.5%), era masculina (66.0%), y racialmente negra (58.1%). La mayoría había experimentado estigma declarado (53.1%). Además, 56.5% y 65.2% mostro niveles de síntomas leves a moderados/severos de ansiedad y depresión, respectivamente. Aquellos que experimentaron cualquier nivel de estigma declarado (vs ninguno) tenían mayores probabilidades de niveles de síntomas leves y moderados/severos de ansiedad (vs ninguno) (ORa[IC] 1.54[1.13, 2.10], p = 0.006; ORa[IC] 3.36[2.14, 5.26], p < 0.001, respectivamente) y depresión (ORa[IC] 1.61[1.19, 2.18], p = 0.002; ORa[IC] 3.66[2.32, 5.77], p < 0.001, respectivamente). Los resultados sugieren la necesidad de evaluar las intervenciones para las personas que viven con VIH para reducir los efectos nocivos del estigma declarado en la salud mental.

Stigmatizing Experiences of Trans Men in Puerto Rico: Implications for Health.

Purpose: The past decade has seen an increase in efforts aimed at understanding the health needs of the transgender population. In the context of Puerto Rico (PR), those efforts have primarily focused on trans women due to their high human immunodeficiency virus (HIV) incidence. However, due to the low impact of the HIV epidemic among trans men, this remains an understudied population in PR. Thus, it is important that research efforts ad- dress the health care needs of trans men in a range of cultural settings, including PR. Recent literature emphasizes the role of stigmatization as a social determinant associated with deleterious health consequences for diverse groups. Despite this worrisome scenario, little is known about how trans men in PR experience and are negatively impacted by social stigma. The objective of this study was to document the stigmatization experiences faced by trans men in PR and its impact on their overall health. Methods: We conducted an exploratory qualitative study with 29 trans men. We implemented focus groups and in-depth qualitative interviews. Thematic analysis guided our interpretation of the findings. Results: Three categories of stigma are discussed: (1) structural stigmatization, (2) interpersonal stigmatization, and (3) individual stigmatization. The health implications of these stigma experiences are discussed. Conclusion: This study represents an initial step toward understanding the social context of this "invisible" community and its health and well-being. We provide recommendations to address social and health concerns related to this understudied community.

Health Care-Specific Enacted HIV-Related Stigma's Association with Antiretroviral Therapy Adherence and Viral Suppression Among People Living with HIV in Florida.

Among people living with HIV (PLWH) in Florida, <2/3 are virally suppressed (viral load <200 copies/mL). Previous theoretical frameworks have pointed to HIV-related stigma as an important factor for viral suppression; an important outcome related to the HIV continuum of care. This study aims to analyze the association between enacted HIV-related stigma and antiretroviral therapy (ART) adherence and viral suppression among a sample of PLWH in Florida. The overall sample (n = 932) was male (66.0%), majority greater than 45 years of age (63.5%), black (58.1%), and non-Hispanic (79.7%). Adjusted odds ratios (AOR) and 95% confidence intervals (CI) were estimated using logistic regression models. The odds of nonadherence to ART was not significantly greater for those reporting low/moderate or high levels of general enacted HIV-related stigma (vs. no stigma) [AOR = 1.30, CI: (0.87-1.95), p = 0.198; AOR = 1.17, CI: (0.65-2.11), p = 0.600, respectively]. Moreover, the odds of nonviral suppression were not significantly greater for those reporting low/moderate or high levels of general enacted HIV-related stigma (vs. no stigma) [AOR = 0.92, CI: (0.60-1.42), p = 0.702; AOR = 1.16, CI: (0.64-2.13), p = 0.622, respectively]. However, ever experiencing health care-specific enacted HIV-related stigma was associated with both nonadherence [AOR = 2.29, CI: (1.25-4.20), p = 0.008] and nonsuppression [AOR = 2.16, CI: (1.19-3.92), p = 0.011]. Despite limitations, the results suggest that the perpetuation of stigma by health care workers may have a larger impact on continuum of care outcomes of PLWH than other sources of enacted stigma. Based on the results, there is a need to develop and evaluate interventions for health care workers intended to reduce experienced stigma among PLWH and improve health outcomes.

HIV and Depression: Examining Medical Students Clinical Skills.

Major depression is a prevalent psychiatric disorder among people living with HIV (PWH). Major depression symptoms, including suicidal ideation, can hinder clinical care engagement and anti-retroviral treatment adherence. Research suggests that inquiry about major depression symptomatology and suicidal ideation should be standard practice when offering primary care services to PWH. However, studies examining depression and suicidal ideation inquiry are scarce. This study's aim was to describe medical students' clinical skills for dealing with major depression symptomatology and suicidal ideation among PWH in Puerto Rico. A total of 100 4th year medical students participated in a Standardized Patient simulation with a trained actor posing as a PWH and with a previous major depression diagnosis. One-way frequency tables were used to characterize the sample and the percentage of each observed clinical skill. Two key findings stem from these results only 10% of the participants referred the patient to psychological/psychiatric treatment, and only 32% inquired about suicidal ideation. Our findings highlight the need for enhancing medical students' competencies regarding mental health issues, particularly when providing services to at risk populations such as PWH within primary care settings.

Decolonial visual resistance as a public health strategy in post-María Puerto Rico.

In this article, we explore the use of the image as a strategy to understand how natural disasters and coloniality impact the health of marginalized communities. We focus on the aftermath of Hurricane María in Puerto Rico and aim to describe how local people used the image as a strategy to challenge the invisibility fostered by coloniality and advocate for a more humane, equitable and effective public health response. We implemented a mixed methods research design including: (1) ethnographic observations, (2) qualitative in-depth interviews with 67 representatives of the health care system, (3) photographs they had taken as part of their experiences during and after the hurricane and (4) images from local newspapers and social media. In light of the findings we argue that Puerto Ricans engaged in decolonial visual resistance to manage the aftermath of the hurricane. Thus, while surviving the natural disaster, they challenged the traditional use of the image in public health endeavours.

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.

"That's all Fake": Health professionals stigma and physical healthcare of people living with Serious Mental Illness.

BACKGROUND: People living with a Serious Mental Illness (SMI) die earlier than the general population due to preventable medical conditions. Latinos living with SMI are a particularly vulnerable population with higher prevalence of chronic medical conditions. Stigma has been identified as a factor that fosters health inequities for Latinos/as with SMI, particularly Puerto Ricans. Although personal and social consequences of stigmatization have been well documented, research regarding the role of cultural factors on healthcare interactions is scarce. Furthermore, little research has focused on addressing stigma from the perspective of healthcare professionals. METHODS: We investigated this process through a qualitative design using semi-structured individual interviews with 11 healthcare professionals (8 physicians and 3 nurses) in Puerto Rico. We conducted a thematic analysis to analyze the data. RESULTS: Following a thematic analysis, we found three main themes and nine sub-themes related to the stigmatization process. Some participants reported perceptions of dangerousness and uneasiness, social distance and inadequate care. Participants also emphasized a lack of medical training regarding SMI within the Puerto Rican context. CONCLUSIONS: These findings support the need to develop culturally appropriate public health interventions targeting healthcare professionals in order to address stigma and eliminate health disparities among Latinos/as with SMI.

HIV/AIDS stigma manifestations during clinical interactions with MSM in Puerto Rico.

HIV/AIDS stigma can have detrimental effects on physician/patient interactions when manifested by health professionals. Unfortunately, HIV/AIDS stigma is usually manifested in an intersectional manner with other pre-existing stigmas, including stigma towards men who have sex with men (MSM). Therefore, our study aimed to examine the behavioral manifestations of HIV/AIDS stigma among physicians in training during simulated clinical interactions with MSM, and explore the interrelation between HIV/AIDS stigma attitudes and behaviors. We implemented an experimental design using Standardized Patient simulations with a sample of 100 physicians in training in Puerto Rico. Results show a significant difference in the two groups' means (p<.001), with a higher number of stigma behaviors in the HIV MSM patient condition (M=6.39) than the common cold control condition (M=5.20). Results evidence that stigma manifestations towards MSM with HIV may continue to be an obstacle for public health in Puerto Rico, and that medical training to prevent stigma is still needed.

Introduction to the special issue: Applying a Caribbean perspective to an analysis of HIV/AIDS.

This introduction presents a special issue of Global Public Health with a collection of articles that offer multidisciplinary perspectives on HIV/AIDS in the Caribbean. Since the 1990s, poverty, marginalisation, and social stigma have been strong foci of much social science research on HIV/AIDS in the region. These three interrelated phenomena have been offered as explanatory factors contributing to the high prevalence of cases observed in this region. Contributors to this special issue take these emphases in new directions, asking multi-level questions that require unique combinations of epidemiological, social scientific, theoretical, and policy-oriented perspectives and methodologies. Together, they identify several topical areas that intend to create dialogue across disciplines and dialectics, with the fundamental principle that the factors relevant to HIV/AIDS are broad and require intersectional lenses. The articles in this issue offer multi-level interventions into HIV/AIDS in the region, from the varied social circumstances that shape heightened risk factors to patient adherence programmes, with emphases on structural, social, and policy-level approaches. Collectively, this special issue establishes the importance of transdisciplinary approaches to HIV/AIDS that are macro-level in scope, but simultaneously attend to how large-scale dynamics are inflected in situated contexts and histories.
