RESUMO

Neuropathies secondary to tophus compression in gout patients are well known; however, limited data exist on other types of peripheral neuropathies (PN). Our aim was to describe PN frequency, characteristics, distribution, patterns, and associated factors in gout patients through clinical evaluation, a PN questionnaire, and nerve conduction studies (NCS). This cross-sectional descriptive study included consecutive gout patients (ACR/EULAR 2015 criteria) from our clinic. All underwent evaluation by Rheumatology and Rehabilitation departments, with IRB approval. Based on NCS, patients were categorized as PN + (presence) or PN- (absence). PN + patients were further classified as local peripheral neuropathy (LPN) or generalized somatic peripheral neuropathy (GPN). We enrolled 162 patients, 98% male (72% tophaceous gout). Mean age (SD): 49.4 (12) years; mean BMI: 27.9 (6.0) kg/m2. Comorbidities included dyslipidemia (53%), hypertension (28%), and obesity (23.5%). Abnormal NCS: 65% (n = 106); 52% LPN, 48% GPN. PN + patients were older, had lower education, and severe tophaceous gout. GPN patients were older, had lower education, and higher DN4 scores compared to LPN or PN- groups (p = 0.05); other risk factors were not significant. Over half of gout patients experienced neuropathy, with 48% having multiplex mononeuropathy or polyneuropathy. This was associated with joint damage and functional impairment. Mechanisms and risk factors remain unclear. Early recognition and management are crucial for optimizing clinical outcomes and quality of life in these patients. Key Points Peripheral neuropathies in gout patients had been scarcely reported and studied. This paper report that: • PN in gout is more frequent and more diverse than previously reported. • Mononeuropathies are frequent, median but also ulnar, peroneal and tibial nerves could be injured. • Unexpected, generalized neuropathies (polyneuropathy and multiplex mononeuropathy) are frequent and associated to severe gout. • The direct role of hyperuricemia /or gout in peripheral nerves require further studies.

RESUMO

BACKGROUND AND OBJECTIVE: Termination of pregnancy in patients with rheumatic diseases is controversial and a bioethical analysis is rarely performed. In this study we analysed the case of a pregnant patient with lupus nephritis unresponsive to treatment, for whom termination of pregnancy is considered. METHODS: The integrative model was applied combining different normative ethical theories. RESULTS: From a utilitarian perspective, termination of pregnancy is justifiable, seeking the greatest benefit for the greatest number of stakeholders. Deontology justifies both terminating and continuing the pregnancy, focusing on the action itself and on autonomy. In virtue ethics the importance of decisions rests with the person who performs the action seeking flourishing; termination of pregnancy would be justifiable. DISCUSSION AND CONCLUSIONS: Interruption of pregnancy is a justifiable solution following the integrative model. Bioethical analysis of paradigmatic cases is essential to ensure the best possible action and as a precedent for future similar situations in rheumatology.

RESUMO

BACKGROUND: Women are the primary caregivers of children in palliative care. Research has shown that the presence of intimate partner violence at home exacerbates the vulnerability of the caregiver. Current statistics indicate a high prevalence of violence in Mexico present in the intersectionality between intimate partner violence and the role of the primary caregiver. This study aimed to describe the frequency of intimate partner violence among primary palliative caregivers at the Hospital Infantil de México Federico Gómez. METHODS: We conducted a cross-sectional and prospective study with convenience sampling; no sample calculation was performed. All female primary caregivers of children in the palliative care unit were invited to participate. The Scale of Violence and Index of Severity of Violence was used as the measuring instrument. RESULTS: One hundred women participated in the study by submitting their survey in a designated mailbox. No sociodemographic data or patient diagnoses were collected. The frequency of intimate partner violence was 28%, of which 16% were considered severe cases. Women reported psychological violence (36%), sexual violence (23%), and physical violence (22%). CONCLUSIONS: Almost one-third of female primary caregivers of pediatric patients at the Hospital Infantil de México Federico Gómez have been victims of some form of violence by current partners. This study highlights a previously unreported problem and opens the door for studies to correlate intimate partner violence among primary caregivers and the quality of life of children in palliative care.

RESUMO

BACKGROUND: Chronic musculoskeletal (MSK) diseases are an important cause of disability in the Mayan community of Chankom in Yucatán, Mexico. OBJECTIVE: To understand a community-based participatory research (CBPR) strategy implemented in Chankom to design a community-based rehabilitation (CBR) program for people living with MSK diseases. METHODS: Qualitative descriptive thematic analysis from an ethnographic work conducted in Chankom, during the implementation of a CBPR strategy from 2014 to 2017. RESULTS: Four main themes describe the main processes that formed our CBPR strategy: 1) forming and maintaining an alliance between academic and community members, 2) prioritizing community needs, 3) integrating local and global knowledge and 4) shared-decision-making. This CBPR strategy allowed the design of a CBR program formed by six main interventions: 1) health services coordination, 2) personal support, 3) community venous blood sampling services, 4) community specialized services, 5) health promotion, and 6) health transportation services. CONCLUSIONS: Co-designing a CBR program for people living with chronic MSK diseases in Chankom was possible through an extensive community engagement work structured around four main processes, including the essential principles of CBPR. The designed CBR program includes culturally sensitive interventions aimed at improving the quality, availability, accessibility, and acceptability of health care services. Moreover, the program mainly addressed the "health" component of the World Health Organization-CBR matrix, suggesting a need for a new CBPR cycle after it is implemented and evaluated in the future.

RESUMO

In this issue of The Journal of Rheumatology, Xiang et al1 describe the experience and influencing factors of symptom appraisal and help-seeking among patients with various autoimmune rheumatic diseases (ARDs) in a multiethnic urban Asian population.The authors guided the interpretation of this qualitative study based on the social cognitive theory framework to enhance the appraisal of symptoms and help-seeking.

RESUMO

INTRODUCTION/OBJECTIVES: Active autoimmune rheumatic diseases (ARDs) before conception increase the risk of flares and adverse pregnancy outcomes. We aimed to construct and validate a reproductive behavior questionnaire in Spanish for patients with ARDs to assess their knowledge and their reproductive behavior. METHOD: We constructed and validated a reproductive behavior questionnaire in two phases: (1) a literature review followed by interviews of reproductive-age female patients, and (2) a cross-sectional study to complete validation. Convenience sampling was carried out with 165 female patients: 65 participated in the cross-cultural adaptation phase and 100 in the validation phase. The internal consistency was evaluated by estimating Cronbach's alpha and tetrachoric correlation coefficients. Values ≥ 0.40 were considered acceptable (p < 0.05). RESULTS: The initial instrument included 38 questions. Thematic analysis identified 8 important dimensions or topics, which were combined to create the Rheuma Reproductive Behavior interview questionnaire. A final total of 41 items across 10 dimensions were obtained. The test-retest analysis showed perfect correlations in 34 of the 41 items, moderate in 6 items, and negative in one of the items. The mean age of the patients was 35.65 years (SD 9.02), and the mean time to answer the survey was 13.66 min (SD 7.1). CONCLUSIONS: The Rheuma Reproductive Behavior questionnaire showed good reliability and consistency capturing patients' reproductive health knowledge and reproductive behavior. Key Points • We designed and validated a questionnaire to assess reproductive health knowledge and reproductive behavior among female patients with ARDs. • The questionnaire was comprehensible for participants, and showed good reliability and consistency capturing reproductive knowledge and behavior. • This tool may aid in the design of strategies to improve reproductive decision-making for female patients with ARDs.

RESUMO

The attitudes toward emerging COVID-19 vaccines have been of great interest worldwide, especially among vulnerable populations such as patients with rheumatic and musculoskeletal diseases (RMDs). The aim of this study was to analyze the relationship between the nationwide number of COVID-19 cases and deaths, and vaccine acceptance or hesitancy of patients with RMDs from four patient care centers in Mexico. Furthermore, we explored differences in acceptance according to specific diagnoses: rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE). This ecological study was a secondary analysis of a cross-sectional study using a validated questionnaire to measure vaccine acceptance. We generated a global Likert scale to evaluate overall attitudes toward the COVID-19 vaccine. We analyzed data from 1336 patients from March to September 2021: 85.13% (1169) were women, with a mean age of 47.87 (SD 14.14) years. The most frequent diagnoses were RA (42.85%, 559) and SLE (27.08%, 393). 635(47.52%) patients were unvaccinated, 253(18.93%) had one dose and 478(35.77%) had two doses. Of all participating patients, 94% were accepting toward the COVID-19 vaccine. Vaccine acceptance remained consistently high throughout the study. However, differences in vaccine acceptance are identified when comparing diagnoses. The peak of the national epidemic curve coincided with an increase in hesitancy among patients with RA. Contrastingly, patients with SLE became more accepting as the epidemic curve peaked. Mexican patients show high acceptance of the COVID-19 vaccine, influenced in part by a patient's specific diagnosis. Furthermore, vaccine acceptance increased mirroring the curve of COVID-19 cases and deaths in the country. This should be taken into consideration when updating recommendations for clinical practice.

RESUMO

BACKGROUND: Chikungunya virus (CHIKV) diagnosis has become a challenge for primary care physicians in areas where the Zika virus and/or Dengue virus are present. Case definitions for the three arboviral infections overlap. METHODS: A cross-sectional analysis was carried out. A bivariate analysis was made using confirmed CHIKV infection as the outcome. Variables with significant statistical association were included in an agreement consensus. Agreed variables were analyzed in a multiple regression model. The area under the receiver operating characteristic (ROC) curve was calculated to determine a cut-off value and performance. RESULTS: 295 patients with confirmed CHIKV infection were included. A screening tool was created using symmetric arthritis (4 points), fatigue (3 points), rash (2 points), and ankle joint pain (1 point). The ROC curve identified a cut-off value, and a score ≥ 5.5 was considered positive for identifying CHIKV patients with a sensibility of 64.4% and a specificity of 87.4%, positive predictive value of 85.5%, negative predictive value of 67.7%, area under the curve of 0.72, and an accuracy of 75%. CONCLUSION: We developed a screening tool for CHIKV diagnosis using only clinical symptoms as well as proposed an algorithm to aid the primary care physician.

RESUMO

Syndemics are a framework that documents health inequities and vulnerabilities in populations with rheumatic diseases. Compared with other approaches, syndemics are able to conjunctly consider epidemiological, biological, sociodemographic and economic factors, and their interactions. OBJECTIVE: To estimate health inequity and vulnerability among Indigenous and non-Indigenous populations with rheumatic and musculoskeletal diseases (RMD) in Latin America using the syndemic approach. DESIGN: This is a secondary analysis of a previously published large-scale study on the prevalence of RMD. SETTING: Studies carried out in five Latin American countries (Argentina, Colombia, Ecuador, Mexico and Venezuela). Health inequity and vulnerability in RMD were identified through a syndemic approach using network and cluster analysis. PARTICIPANTS: A total of 44 560 individuals were studied: 29.78% self-identified as Indigenous, 60.92% were female, the mean age was 43.25 years. Twenty clusters were identified in the Indigenous population and 17 in the non-Indigenous population. RESULTS: The variables associated with RMD among Indigenous populations were rurality, public health system, high joint biomechanical stress, greater pain, disability and alcoholism; and among non-Indigenous people they were being a woman, urban origin, older age, private health system, joint biomechanical stress, greater pain and disability. We identified different health inequities among patients with RMD (ie, lower educational attainment, more comorbidities), associated with factors such as Indigenous self-identification and rural residence. CONCLUSIONS: A syndemic approach enables us to identify health inequities in RMD, as shown by higher prevalence of comorbidities, disability and socioeconomic factors like lower educational attainment. These inequities exist for the overall population of patients with RMD, although it is more evident in Indigenous groups with added layers of vulnerability.

RESUMO

Introduction: The objective was to adapt and valídate in a culturally sensitive way the methodology of the community-oriented programme for the control of rheumatic diseases (COPCORD) in the indigenous Misak community of Colombia. Material and methods: A culturally sensitive validation of the COPCORD questionnaire in Spanish was carried out, translating into the nam trik wam language used by the Misak community of Guambia town. It was adapted to the context of this population and later a back-translation to Spanish was carried out. Finally, it was validated applying the survey with the support of bilingual translators. Participants with pain, stiffness or swelling in any joint in the previous 7 days and/or at any time in life were evaluated by physicians and physiotherapists and were then, upon confirming the diagnosis of a musculoskeletal disorder, subsequently examined by a rheumatologist. Results: In this population (n = 106), 58.5% were women with an average age of 45.5 years. In the last 7 days, 51 subjects (48.1%) reported having musculoskeletal pain and 7 (44.3%) reported pain at some time in their life. Of those who received treatment, 53.1% reported using traditional medicine, 34.4% homeopathic treatment, and 25% allopathic treatment. The COPCORD Misak demonstrated an adequate capacity to detect musculoskeletal disorders, with a sensitivity of 63.3% and a specificity of 80.3%, with a positive likelihood ratio of 3.2, and area under the curve of.71. Conclusion: The COPCORD methodology is a valid screening tool to detect musculoskeletal disorders in the Misak community.

Introducción: El objetivo fue adaptar y validar, de forma culturalmente sensible, la metodología del Programa orientado a la comunidad para el control de enfermedades reumáticas (COPCORD) en la comunidad indígena misak de Colombia. Material y métodos: Se realizó una validación culturalmente sensible del cuestionario Copcord en español, que se tradujo al nam trik wam, lengua usada por el pueblo misak del resguardo de Guambia. El cuestionario se adecuó al contexto de esta población y posteriormente se llevó a cabo una retrotraducción al español. Por último, se validó aplicando la encuesta con el apoyo de traductores bilingües. Los participantes con dolor, rigidez o hinchazón en cualquier articulación en los siete días previos, o en cualquier momento de la vida, fueron evaluados por médicos y fisioterapeutas. Al confirmarse el diagnóstico de una enfermedad musculoesquelética los participantes eran examinados por un reumatólogo. Resultados: De la población estudiada (n = 106) el 58,5% fueron mujeres, con una edad promedio de 45,4 arios. En los últimos siete días, 51 sujetos (48,1%) informaron tener dolor musculoesquelético y siete (44,3%) refirieron dolor en algún momento de su vida. Quienes recibieron tratamiento reportaron el uso de medicamentos tradicionales en un 53,1% de los casos, homeopáticos en el 34,4% y alopáticos en el 25%. El cuestionario COPCORD Misak demostró una adecuada capacidad para detectar los trastornos musculoesqueléticos, con una sensibilidad del 63,3%, una especificidad del 80,3%, una razón de verosimilitud positiva de 3,2 y un área bajo la curva de 0,71. Conclusión: La metodología COPCORD es una herramienta válida de cribado de enfermedades musculoesqueléticas en el pueblo misak.

RESUMO

Backyard animal husbandry is common in rural communities in developing countries and, given the conditions in which it occurs, it can increase the risk of disease transmission, such as arboviruses. To determine the presence of the Zika virus (ZIKV) and abundance of its arthropod vectors we evaluated the socioeconomic implications involved in its transmission in two highly vulnerable Mayan communities in the state of Yucatan that practice backyard farming. An analytical cross-sectional study was carried out throughout 2016 to understand socioeconomic variables and seasonal patterns in mosquito populations. We selected 20 households from each community. Social exclusion indicators were analyzed, human and domestic animals were sampled, and mosquitoes were collected and identified. Four out of eight indicators of social exclusion were higher than the reported national averages. We captured 5,825 mosquitoes from 16 species being Culex quinquefasciatus and Aedes aegypti the most abundant. The presence of chickens and human overcrowding in dwellings were the most significant factors (P = 0.026) associated with the presence of Ae. aegypti. Septic tanks (odds ratio = 6.64) and chickens (odds ratio = 27.41) in backyards were the main risk factors associated with the presence of immature states of Ae. aegypti in both communities. Molecular analysis to detect ZIKV was performed in blood samples from 416 humans, 1,068 backyard animals and 381 mosquito pools. Eighteen humans and 10 pig pools tested positive for ZIKV. Forty-three mosquito pools tested positive for flavivirus. Ten of the 43 pools of positive mosquitoes were sequenced, corresponding 3/10 to ZIKV and 1/10 to Dengue virus type 2. The findings obtained indicate the continuous circulation of Flavivirus (including ZIKV) in backyard environments in vulnerable communities, highlighting the importance of studying their transmission and maintenance in these systems, due that backyard animal husbandry is a common practice in these vulnerable communities with limited access to health services.

RESUMO

INTRODUCTION: The use of online education strategies has been introduced as a tool to support health care in patients with rheumatic disease. However, it is important to consider the patient's sociocultural environment. OBJECTIVE: To design and assessment of bilingual audiovisual material acceptability, by means of two social networks, for patients with rheumatoid arthritis (RA) in the qom community in Argentina. METHODS: A qualitative study was performed in two stages: (1) audiovisual material design, development, and validation implementing a collaborative action research method. (2) Publishing of the material on two social networks at two different times. The selected topic was the coronavirus disease 2019 impact on patients with RA. A qualitative and quantitative data analysis was performed. RESULTS: Forty subjects participated into the initial validation stage with a 70% acceptance rate. First, 28 subjects (70%) participated on Facebook and 25 (62.5%) joined the WhatsApp group. Then, the same number of subjects participated on Facebook, while only 45% of subjects participated on WhatsApp. Most of them participated using short phrases such as "I like it." The 60% of the participants played the videos. However, less than 10% shared them. Videos in Spanish were the once most shared. Participation dramatically fell during the second time, and 40% of the WhatsApp subjects never participated. CONCLUSION: The strategies developed for this indigenous community were of no utility, probably because of socio-cultural, economic, and digital barriers. They should be designed and implemented identifying the target group and its environment. Key Points • Online education strategies should be designed with cultural sensitivity. • Technological barriers make digital inequality visible in vulnerable groups. • Educational interventions should have a collaborative design and they should be created together with the communities. • The COVID-19 pandemic has deepened inequalities in the health care and follow-up of patients with rheumatic diseases, especially between most socially and economically disadvantaged groups.

RESUMO

OBJECTIVES: Risk perception of the COVID-19 pandemic may affect chronic disease outcomes among patients with rheumatic diseases (RD). To describe and compare the perception of risk and effects of the COVID-19 pandemic on patients with RD from two health care centers compared with a control group. METHODS: A retrospective case-control study was conducted. Patient respondents completed an online survey to measure risk perception and effects of the COVID-19 pandemic. The case group consisted of patients with a confirmed diagnosis of RD, coming from two third-level health care centers. The control group was a population group without RD from a public university. RESULTS: A total of 3944 participants were included: 986 patients with an RD (cases) from the two hospital centers and 2958 controls without RD. A greater perception of risk severity and perception of contagion was observed in the group of patients with RD, OR: 1.70, 95% CI 1.44‒2.01 and OR: 2.0, 95% CI 1.79‒2.23, respectively; more significant deterioration in family life OR: 1.14, 95% CI 1.01‒1.29; greater economic impact, OR 3.94, 95% CI 3.48‒4.46; as well as negative emotions and feelings (alarmed, anxiety, depression, confusion, fear, isolation, and discrimination). This impact was maintained when the model was adjusted for comorbidities. CONCLUSION: In the face of an unexpected and catastrophic event such as the COVID-19 pandemic, patients with RD report apparently greater impact on their mental state and economic situation than the control population, as well as increased perception of discrimination. Key Points • The multidisciplinary analyses of risk perception are required to promote actions that can enhance the preparedness and responses of public efforts for possible future pandemics in a way that considers the specific needs of vulnerable people like patients with rheumatic diseases. • Identifying risk perceptions of possible effects of the pandemic, sources of communication, and opinions is essential to ensure self-care in rheumatic disease. • The impact of COVID-19 has been much greater for people with rheumatic disease, especially in terms of the perceived severity of the pandemic, impacts on family and economy, preventive behaviors, and uncertainty.

RESUMO

INTRODUCTION: To describe and understand the attitudes, cultural knowledge, and therapeutic practices of the Misak people concerning rheumatoid arthritis (RA), inscribed in an emergent culturally sensitive healthcare model along with the indigenous community and health professionals, following a respectful and empathic relational contact approach to the inter-ethnic encounter. METHODS: A qualitative study that used ethnographic methods using observation techniques and in-depth interviews was carried out in the Misak community, Colombia, by a multidisciplinary team (rheumatology, physiotherapy, and anthropology). A thematic analysis based around the concept of explanatory models (EMs) was carried out. RESULTS: Researchers interviewed 20 patients with RA, 12 traditional healers, and 5 health professionals. The following themes were identified: (1) the traditional healers are allowed to practice only if the community recognizes their vocation; (2) two types of EM were observed: Misak community EM related to conception of RA and its treatment, shared by patients and the traditional healers; and biomedical EM. The interaction of the two types is still a healthcare challenge that requires articulating to achieve better clinical outcomes for patients. CONCLUSION: The EMs of RA care identified in the Misak community are focused on both the patients and the traditional healers. However, this predominant EM and the biomedical EM of RA care need to be brought closer together to contribute to the construction of a unifying model of a culturally sensitive care.

RESUMO

COVID-19 vaccination is recommended in patients with rheumatic diseases (RDs) to prevent hospitalized COVID-19 and worse outcomes. However, patients' willingness to receive a SARS-CoV-2 vaccine and the associated factors vary across populations, vaccines, and time. The objective was to identify factors associated with COVID-19 vaccine acceptance (VA) in Mexican outpatients with RDs. This multicenter study was performed between March 1 and September 30, 2021, and four national centers contributed with patients. Participants filled out a questionnaire, which included 32 items related to patients' perception of the patient-doctor relationship, the COVID-19 vaccine component, the pandemic severity, the RD-related disability, comorbid conditions control, immunosuppressive treatment impact on the immune system, and moral/civil position of COVID-19 vaccine. Sociodemographic, disease-related, and treatment-related variables and previous influenza record vaccination were also obtained. Multiple logistic regression analyses identified factors associated with VA, which was defined based on a questionnaire validated in our population. There were 1439 patients whose data were analyzed, and the most frequent diagnoses were Rheumatoid Arthritis in 577 patients (40.1%) and Systemic Lupus Erythematosus in 427 (29.7%). Patients were primarily middle-aged women (1235 [85.8%]), with (mean±SD) 12.1 (±4.4) years of formal education. Years of education, corticosteroid use, patient perceptions about the vaccine and the pandemic severity, patient civil/moral position regarding COVID-19 vaccine, and previous influenza vaccination were associated with VA. In Mexican patients with RDs, COVID-19 VA is associated with individual social-demographic and disease-related factors, patient´s perceptions, and previous record vaccination. This information is crucial for tailoring effective vaccine messaging in Mexican patients with RDs.

RESUMO

Chikungunya virus (CHIKV) is an alphavirus from the Togaviridae family that causes acute arthropathy in humans. It is an arthropod-borne virus transmitted initially by the Aedes (Ae) aegypti and after 2006's epidemic in La Reunion by Ae albopictus due to an adaptive mutation of alanine for valine in the position 226 of the E1 glycoprotein genome (A226V). The first isolated cases of CHIKV were reported in Tanzania, however since its arrival to the Western Hemisphere in 2013, the infection became a pandemic. After a mosquito bite from an infected viremic patient the virus replicates eliciting viremia, fever, rash, myalgia, arthralgia, and arthritis. After the acute phase, CHIKV infection can progress to a chronic stage where rheumatic symptoms can last for several months to years. Although there is a great number of studies on the pathogenesis of CHIKV infection not only in humans but also in animal models, there still gaps in the proper understanding of the disease. To this date, it is unknown why a percentage of patients do not develop clinical symptoms despite having been exposed to the virus and developing an adaptive immune response. Also, controversy stills exist on the pathogenesis of chronic joint symptoms. It is known that host immune response to an infectious disease is reflected on patient's symptoms. At the same time, it is now well-established that host genetic variation is an important component of the varied onset, severity, and outcome of infectious disease. It is essential to understand the interaction between the aetiological agent and the host to know the chronic sequelae of the disease. The present review summarizes the current findings on human host genetics and its relationship with immune response in CHIKV infection.

RESUMO

BACKGROUND: Epidemiological data from Mexico have documented an increase in heroin use in the last decade. However, there is no comprehensive care strategy for heroin users, especially those who have been accused of a crime. The objective of this study was to describe the heroin and methadone use of intravenous heroin users of both sexes who have been in jail, to offer evidence for the formulation of health policy. METHODS: This study used an ethnographic approach, with open-ended interviews carried out from 2014 to the present. Heroin users of both sexes attending a private methadone clinic in Mexico City were invited to participate. The sample was non-probabilistic. All interviews were audiotaped and transcribed, and narratives were analyzed using thematic analysis. RESULTS: Participants in this study were 33 users of heroin, two of them women, who had been in prison. They ranged in age from 33 to 62 years, had used heroin for a period of 13-30 years, and were from three states: Michoacan, Oaxaca, and Mexico City. Three principal categories of analysis were structured: 1. Pilgrimage for help (dynamics of the drama of suffering, pain, and time through health care spaces); 2) methadone use as self-care; and 3) accessibility to methadone treatment. The impossibility of access to methadone treatment is a condition which motivates users in their journey. The dynamics of methadone use are interpreted as a form of self-care and care to avoid substance use. Reducing the psychological, physical, and harmful effects of the substance allows them to perform daily activities. The inability to access treatment leads to a significant effect on users who experience structural violence. CONCLUSION: Compassionate methadone treatment and holistic attention should be considered as a way to meet patients' needs and mitigate their suffering, based on public health policy that allows for human rights-based care.

RESUMO

BACKGROUND: Previous models that assess quality-of-Life (QoL) in patients with rheumatic diseases have a strong biomedical focus. We evaluated the impact of COVID-19 related-health care interruption (HCI) on the physical, psychological, social relationships and environment QoL-dimensions, and explored factors associated with QoL when patients were reincorporated to the outpatient clinic, and after six-month follow-up. PATIENTS AND METHODS: Study phase-1 consisted of a COVID-19 survey administered from June 24th-October 31st 2020, to outpatients with rheumatic diseases who had face-to-face consultation at outpatient clinic reopening. Study phase-2 consisted of 3 consecutive assessments of patient´s QoL (WHOQOL-BREF), disease activity/severity (RAPID-3), and psychological comorbidity/trauma (DASS-21 and IES-R) to patients from phase-1 randomly selected. Sociodemographic, disease and treatment-related information, and comorbidities were obtained. Multiple linear regression analysis identified factors associated with the score assigned to each WHOQOL-BREF dimension. RESULTS: Patients included (670 for phase-1 and 276 for phase-2), had primarily SLE and RA (44.2% and 34.1%, respectively), and all the dimensions of their WHOQOL-BREF were affected. There were 145 patients (52.5%) who referred HCI, and they had significantly lower dimensions scores (but the environment dimension score). Psycho-emotional factors (primarily feeling confused, depression and anxiety), sociodemographic factors (age, COVID-19 negative economic impact, years of scholarship, HCI and having a job), and biomedical factors (RAPID-3 score and corticosteroid use) were associated with baseline QoL dimensions scores. Psycho-emotional factors showed the strongest magnitude on dimensions scores. Most consistent predictor of six-month follow-up QoL dimensions scores was each corresponding baseline dimension score, while social determinants (years of scholarship and having a job), emotional factors (feeling bored), and biomedical aspects (RAPID 3) had an additional impact. CONCLUSIONS: HCI impacted the majority of patient´s QoL dimensions. Psycho-emotional, sociodemographic and biomedical factors were consistently associated with QoL dimensions scores, and these consistently predicted the QoL trajectory.

RESUMO

BACKGROUND: Estimating the burden of rheumatic diseases (RDs) requires proper evaluation of its lethal and nonlethal consequences. In Colombia, it is possible to find local data and Global Burden of Disease (GBD) reports that collect information from varied contexts and apply complex statistical models, but no on-site estimations are available. METHODS: This was a descriptive study on the burden of RD based on occurrence and mortality data in the general population during 2015, including information and prevalence estimations from the Community Oriented Program for the Control of Rheumatic Diseases (COPCORD) study. Disability-adjusted life years (DALYs) were estimated by combining measures of years of life lost (YLL) and years lived with disability (YLDs). For disability weight estimations among cases, different COPCORD responses were mapped using flowcharts to show the severity distribution according to GBD. All model parameters and results were validated through an expert consensus panel. RESULTS: Low back pain (LBP) was the RD with the greatest burden of disease, costing 606.05 (95% CI 502.76-716.58) DALYs per 100,000 inhabitants, followed by osteoarthritis (292.11; 95% CI 205.76-386.85) and rheumatoid arthritis (192.46, 95% CI 109.7-239.69). CONCLUSIONS: The burden of RD is as high in Colombia as in other countries of the region. The results offer an interesting tool for optimizing healthcare system design as well as for planning the distribution of human and economic resources to achieve early diagnosis and adequate care of these diseases.
