RESUMEN

Substance Use Disorder (SUD) has been conceptualized as an outcome of a dysregulated reward system. However, individuals with SUD suffer from anxiety with an intensity depending on the abstinence period length. This review discusses the role of anxiety as a major contributor to the initiation and perpetuation of SUD, and its dependence on an up-regulated defense-antireward system. In addition, it is discussed that sleep debt, and its psychosocial consequences, promote anxiety, contributing to SUD generation and maintenance. Healthy sleep patterns can be disrupted by diverse medical conditions and negative psychosocial interactions, resulting in accumulated sleep debt and anxiety. Within this narrative review, we discuss the interplay between the motivation-reward and defense-antireward systems, framing the progression from recreational drug use to addiction. This interplay is nuanced by sleep debt-induced anxiety and its psychosocial consequences as contributory vulnerability factors in the genesis of addiction.

RESUMEN

Goals of care (Goals-of-care) discussions and palliative care (PC) are crucial to providing comprehensive healthcare, particularly for acute neurological conditions requiring admission to a neurological intensive care unit. We identified gaps in the literature and describe insight for future research on end-of-life discussions and PC for U.S. Latinos with acute neurological conditions. We searched 10 databases including peer-reviewed abstracts and manuscripts of hospitalized U.S. Latinos with acute neurological and non-neurological conditions. We included 44 of 3231 publications and identified various themes: PC utilization, pre-established advanced directives in Goals-of-care discussions, Goals-of-care discussion outcomes, tracheostomy or percutaneous gastrostomy tube placement rates among hospitalized Latinos. Our review highlights that Latinos appear to have lower palliative care utilization compared with non-Latino Whites and may be less likely to have pre-established advanced directives, more likely to have gastrostomy or tracheostomy placement and less likely to have do-not-resuscitate status.

RESUMEN

INTRODUCTION: Depression is prevalent among aging people living with HIV (PLWH) worldwide. We sought to identify depression risk factors among a group of middle-aged and older PLWH in Lima, Peru. MATERIALS AND METHODS: We assessed risk factors for depression among PLWH over age 40 receiving care in an HIV clinic in Lima, Peru. The Patient Health Questionnaire-9 (PHQ-9) was administered. We performed descriptive statistics and logistic regression analyses. RESULTS: Mean age was 51.7 ± 7.7 years with 15.3% females. One-quarter of participants had depression with higher frequency in females. Risk factors that significantly increased the risk of depression included female sex (adjusted prevalence ratio [aPR] = 2.19 [95%CI 1.07-4.49]), currently smoking (aPR = 2.25 [95%CI 1.15-4.43]), and prior opportunistic infection (aPR = 2.24 [95%CI 1.05-4.76]). DISCUSSION: Our study demonstrates that PLWH who are female, current smokers, or had an opportunistic infection have higher risk of depression. Identifying PLWH at-risk for depression is key to early mental health interventions.

RESUMEN

BACKGROUND: Neurocognitive impairment (NCI) may occur during and persist even after recovery from HIV-related CNS co-infections such as toxoplasmic encephalitis (TE). The long-term cognitive effects of TE and latent toxoplomasmic infections (LTI) among persons with HIV (PWH) are unknown. We measured longitudinal effects on NC functioning in PWH with TE compared to LTI or no toxoplasmal infection. METHODS: PWH (n = 345) followed in two longitudinal cohort studies underwent comprehensive neurocognitive assessments and an anti-Toxoplamic IgG assay. Participants were classified into one of three groups: TE+ (n = 39), LTI+ (n = 34), LTI- (n = 272). The primary outcome was change in neurocognitive function between baseline and 7-year visit. RESULTS: The mean age was 48 ±â€Š11 years, mean educational level 13 ±â€Š3 years, and 13% were female. TE+ patients were less likely to have undetectable viral loads (≤50 copies/mL) and had lower absolute CD4 counts. The TE+ group had the highest prevalence of NCI globally and in domains of verbal, executive function, learning, recall, working memory, processing speed and motor at baseline and at 7-year follow-up. Changes in longitudinal NC function over 7 years were small and did not differ significantly among all groups, except that speed of information processing improved more in TE+ compared with LTI- participants. CONCLUSIONS: PWH with a history of TE had cognitive impairment over a broad range of severity at both baseline and last follow-up. Changes in cognition from baseline to last examination in all groups were minimal and did not differ significantly among the groups with the exception of speed of information processing.

RESUMEN

Congenital portosystemic shunts are rare abnormalities in which blood flow from the liver is diverted to the systemic circulation. We would like to present the case of a 48-year-old male, during his neurological follow-up he was diagnosed with a congenital intrahepatic portosystemic shunt. Embolization of the portosystemic communicating veins was attempted on two occasions, but without success. Due to the poor clinical course, the patient was presented to our transplant committee and a liver transplant was decided upon.

RESUMEN

Background: Coronavirus disease 2019 (COVID-19) infection has been associated with severe neurological consequences, including stroke or seizures, and less severe neurological sequelae, including headaches, dizziness, and anosmia. Earlier COVID-19 variants were associated with high morbidity and mortality; however, knowledge of the impact of neurological conditions in the setting of COVID-19 on healthcare outcomes is limited. We sought to determine the impact of acute neurological conditions and acute COVID-19 infection on inpatient hospitalization outcomes. Methods: This was a retrospective, observational study of adult patients who were admitted to a large academic medical center in the Southeastern US between April 2020 and December 2021 with acute COVID-19 infection and a neurological diagnosis. Patient demographics, medical history, neurological diagnoses, and hospitalization outcomes were obtained from the medical record. Descriptive statistics and unadjusted and adjusted logistic regression analyses were performed. Results: Of the 1,387 patients included in this study, 27% died and 23% were kept under ventilation during hospitalization. The mean +/- standard deviation (SD) age was 64.6+/-16.9 years, with 52.8% women and 30.1% identifying as Black/African American. The most common neurological conditions included ischemic stroke (35.0%), movement disorder (12.0%), and hemorrhagic stroke (10.7%). In-hospital death was most common among those with epilepsy (p = 0.024), headache (p = 0.026), and dementia (p < 0.0001) compared to individuals without those conditions. Ventilation support was given more commonly to dementia patients (p = 0.020). Age was a significant risk factor for death (p < 0.001) and hospital length of stay (LOS) for ventilation (p < 0.001), but no neurological condition was a significant factor in adjusted logistic regression analyses. Discussion: Mortality was high in this study, with more than one-quarter of patients dying in the hospital. Death was the most common among those with epilepsy, headache, or dementia, but no neurological condition increased the risk of in-hospital mortality or ventilation. Future studies would determine the long-term neurological sequelae of those discharged from the hospital with COVID-19 and a neurological condition.

RESUMEN

BACKGROUND: Ehrlichiosis is a potentially fatal tick-borne disease that can progress to involve the central nervous system (CNS) (i.e., neuro-ehrlichiosis), particularly in cases where diagnosis and treatment are delayed. Despite a six-fold national increase in the incidence of ehrlichiosis over the past 20 years, recent data on the prevalence and manifestations of neuro-ehrlichiosis are lacking. METHODS: We conducted a retrospective chart review of all patients tested for ehrlichiosis at University of North Carolina Health facilities between 2018 and 2021 and identified patients who met epidemiological criteria for ehrlichiosis as established by the Council of State and Territorial Epidemiologists and employed by the Centers for Disease Control and Prevention. We estimated the prevalence of neurological symptoms and described the spectrum of neurological manifestations in acute ehrlichiosis, documenting select patient cases in more detail in a case series. RESULTS: Out of 55 patients with confirmed or probable ehrlichiosis, five patients (9.1%) had neurologic symptoms, which is notably lower than previous estimates. Neurological presentations were highly variable and included confusion, amnesia, seizures, focal neurological deficits mimicking ischemic vascular events, and an isolated cranial nerve palsy, though all patients had unremarkable neuroimaging at time of presentation. All but one patient had risk factors for severe ehrlichiosis (i.e., older age, immunosuppression). CONCLUSIONS: Neuro-ehrlichiosis may lack unifying patterns in clinical presentation that would otherwise aid in diagnosis. Clinicians should maintain a high index of suspicion for neuro-ehrlichiosis in patients with acute febrile illness, diverse neurological symptoms, and negative neuroimaging in lone star tick endemic regions.

RESUMEN

The presence of skin bacteria capable of forming biofilm, exhibiting antibiotic resistance, and displaying virulence represents a significant challenge in the field of transfusion medicine. This underscores the necessity of enhancing the microbiological safety of blood and blood components against pathogens with virulent characteristics. The aim of this work was to demonstrate bacterial inactivation in plasma by using a photoinactivation method against virulent bacteria and to evaluate coagulation factors before and after treatment. Logarithmic loads of biofilm-producing, antibiotic-resistant, and virulent bacteria isolated from skin (Enterobacter cloacae, Klebsiella ozaenae, and Staphylococcus epidermidis) were used in artificial contamination assays of fresh frozen plasma bags and subjected to photoreduction. FVIII and FI activity were evaluated before and after photoinactivation. The photoinactivation of plasma was demonstrated to be an effective method for the elimination of these bacteria. However, the efficiency of this method was found to be dependent on the bacterial load and the type of test microorganism. Conversely, decay of coagulation factors was observed with net residual activities of 61 and 69% for FVIII and FI, respectively. The photoinactivation system could have a bias in its effectiveness that is dependent on the test pathogen. These findings highlight the importance of employing technologies that increase the safety of the recipient of blood and/or blood components, especially against virulent bacteria, and show the relevance of the role of photoinactivation systems as an option in transfusion practice.

RESUMEN

The transport sector is considered the largest contributor of air pollutants in urban areas, mainly on-road vehicles, affecting the environment and human health. Bahía Blanca is a medium-sized Latin American city, with high levels of traffic in the downtown area during peak hours. In this regard, it is necessary to analyze air pollution using an air quality model considering that there are no air pollutant measurements in the central area. Furthermore, this type of study has not been carried out in the region and since the city is expected to grow, it is necessary to evaluate the current situation in order to make effective future decisions. In this sense, the AERMOD model (US-EPA version) and the RLINE source type were used in this work. This study analyzes the variations of pollutant concentrations coming from mobile sources in Bahía Blanca's downtown area, particularly carbon monoxide (CO) and nitrogen oxides (NOx) during the period Jul-2020 to Jun-2022. It is interesting to note the results show the maximum concentration values detected are not directly associated with maximum levels of vehicle flow or emission rates, which highlights the importance of meteorological parameters in the modeling. In addition, alternative scenarios are proposed and analyzed from a sustainable approach. Regarding the scenario analysis, it can be concluded that diesel vehicles have a large influence on NOx emissions. Moreover, restrictions as strict as those proposed for a Low Emission Zone would be less applicable in the city than alternative temporary measures that modify traffic at peak hours.

RESUMEN

Long COVID (LongC) is associated with a myriad of symptoms including cognitive impairment. We reported at the beginning of the COVID-19 pandemic that neuronal-enriched or L1CAM+ extracellular vesicles (nEVs) from people with LongC contained proteins associated with Alzheimer's disease (AD). Since that time, a subset of people with prior COVID infection continue to report neurological problems more than three months after infection. Blood markers to better characterize LongC are elusive. To further identify neuronal proteins associated with LongC, we maximized the number of nEVs isolated from plasma by developing a hybrid EV Microfluidic Affinity Purification (EV-MAP) technique. We isolated nEVs from people with LongC and neurological complaints, AD, and HIV infection with mild cognitive impairment. Using the OLINK platform that assesses 384 neurological proteins, we identified 11 significant proteins increased in LongC and 2 decreased (BST1, GGT1). Fourteen proteins were increased in AD and forty proteins associated with HIV cognitive impairment were elevated with one decreased (IVD). One common protein (BST1) was decreased in LongC and increased in HIV. Six proteins (MIF, ENO1, MESD, NUDT5, TNFSF14 and FYB1) were expressed in both LongC and AD and no proteins were common to HIV and AD. This study begins to identify differences and similarities in the neuronal response to LongC versus AD and HIV infection.

RESUMEN

Case studies present students with an opportunity to learn and apply course content through problem solving and critical thinking. Supported by the High-throughput Discovery Science & Inquiry-based Case Studies for Today's Students (HITS) Research Coordination Network, our interdisciplinary team designed, implemented, and assessed two case study modules entitled "You Are What You Eat." Collectively, the case study modules present students with an opportunity to engage in experimental research design and the ethical considerations regarding microbiome research and society. In this manuscript, we provide instructors with tools for adopting or adapting the research design and/or the ethics modules. To date, the case has been implemented using two modalities (remote and in-person) in three courses (Microbiology, Physiology, and Neuroscience), engaging over 200 undergraduate students. Our assessment data demonstrate gains in content knowledge and students' perception of learning following case study implementation. Furthermore, when reflecting on our experiences and student feedback, we identified ways in which the case study could be modified for different settings. In this way, we hope that the "You Are What You Eat" case study modules can be implemented widely by instructors to promote problem solving and critical thinking in the traditional classroom or laboratory setting when discussing next-generation sequencing and/or metagenomics research.

RESUMEN

The destructive impact of fungi in agriculture and animal and human health, coincident with increases in antifungal resistance, underscores the need for new and alternative drug targets to counteract these trends. Cellular metabolism relies on many intermediates with intrinsic toxicity and promiscuous enzymatic activity generates others. Fuller knowledge of these toxic entities and their generation may offer opportunities of antifungal development. From this perspective our observation of media-conditional lethal metabolism in respiratory mutants of the opportunistic fungal pathogen Candida albicans was of interest. C. albicans mutants defective in NADH:ubiquinone oxidoreductase (Complex I of the electron transport chain) exhibit normal growth in synthetic complete medium. In YPD medium, however, the mutants grow normally until early stationary phase whereupon a dramatic loss of viability occurs. Upwards of 90% of cells die over the subsequent four to six hours with a loss of membrane integrity. The extent of cell death was proportional to the amount of BactoPeptone, and to a lesser extent, the amount of yeast extract. YPD medium conditioned by growth of the mutant was toxic to wild-type cells indicating mutant metabolism established a toxic milieu in the media. Conditioned media contained a volatile component that contributed to toxicity, but only in the presence of a component of BactoPeptone. Fractionation experiments revealed purine nucleosides or bases as the synergistic component. GC-mass spectrometry analysis revealed acetal (1,1-diethoxyethane) as the active volatile. This previously unreported and lethal synergistic interaction of acetal and purines suggests a hitherto unrecognized toxic metabolism potentially exploitable in the search for antifungal targets.

RESUMEN

Distal sensory polyneuropathy (DSP) is a disabling, chronic condition in people with HIV (PWH), even those with viral suppression of antiretroviral therapy (ART), and with a wide range of complications, such as reduced quality of life. Previous studies demonstrated that DSP is associated with inflammatory cytokines in PWH. Adhesion molecules, essential for normal vascular function, are perturbed in HIV and other conditions linked to DSP, but the link between adhesion molecules and DSP in PWH is unknown. This study aimed to determine whether DSP signs and symptoms were associated with a panel of plasma biomarkers of inflammation (d-dimer, sTNFRII, MCP-1, IL-6, IL-8, IP-10, sCD14) and vascular I integrity (ICAM-1, VCAM-1, uPAR, MMP-2, VEGF, uPAR, TIMP-1, TIMP-2) and differed between PWH and people without HIV (PWoH). A cross-sectional study was conducted among 143 participants (69 PWH and 74 PWoH) assessed by studies at the UC San Diego HIV Neurobehavioral Research Program. DSP signs and symptoms were clinically assessed for all participants. DSP was defined as two or more DSP signs: bilateral symmetrically reduced distal vibration, sharp sensation, and ankle reflexes. Participant-reported symptoms were neuropathic pain, paresthesias, and loss of sensation. Factor analyses reduced the dimensionality of the 15 biomarkers among all participants, yielding six factors. Logistic regression was used to assess the associations between biomarkers and DSP signs and symptoms, controlling for relevant demographic and clinical covariates. The 143 participants were 48.3% PWH, 47 (32.9%) women, and 47 (33.6%) Hispanics, with a mean age of 44.3 ± 12.9 years. Among PWH, the median (IQR) nadir and current CD4+ T-cells were 300 (178-448) and 643 (502-839), respectively. Participants with DSP were older but had similar distributions of gender and ethnicity to those without DSP. Multiple logistic regression showed that Factor 2 (sTNFRII and VCAM-1) and Factor 4 (MMP-2) were independently associated with DSP signs in both PWH and PWoH (OR [95% CI]: 5.45 [1.42-21.00], and 15.16 [1.07-215.22]), respectively. These findings suggest that inflammation and vascular integrity alterations may contribute to DSP pathogenesis in PWH, but not PWoH, possibly through endothelial dysfunction and axonal degeneration.

RESUMEN

Objetivo: El propósito del presente estudio es identificar en qué medida la ecografía reumatológica afecta a las decisiones clínicas mediante un estudio unicéntrico observacional retrospectivo. Método: Se analizaron los resultados de 801 solicitudes y 1174 ecografías individuales consecutivas realizadas a lo largo de 10 meses. Resultados: La indicación más frecuente fue la asistencia diagnóstica (39%) seguida de la evaluación de actividad inflamatoria (34%). Por topografía, la mano fue la región más estudiada (51%), seguida del pie (18,1%). De todas las solicitudes, en el 67% se constató un impacto en la toma de decisiones. El impacto en la decisión clínica se asoció a un menor tiempo de espera hasta la evaluación de los resultados, siendo el mayor en aquellas ecografías realizadas a demanda el mismo día de su petición. En el 73% de los estudios ecográficos bilaterales, los hallazgos en una de las articulaciones ejemplificaban el resultado global emitido. Conclusiones: La ecografía reumatológica demuestra ser una técnica útil en la toma de decisiones, cuyo mayor impacto se constata cuanto menor es el tiempo de espera hasta la evaluación de los resultados.(AU)


Objective: The purpose of the present study is to identify the extent to which rheumatological musculoskeletal ultrasound affects clinical decisions in a single-centre observational retrospective study. Method: The results of 801 requests and 1174 consecutive individual ultrasound examinations performed over 10 months were analysed. Results: The most frequent indication was diagnostic assistance (39%) followed by assessment of inflammatory activity (34%). By topography, the hand was the most frequently studied region (51%), followed by the foot (18.1%). Of all requests, 67% had an impact on decision-making. The impact on clinical decision-making was associated with a shorter waiting time for the evaluation of the results, being the greatest in those ultrasound scans performed on demand on the same day of the request. In 73% of bilateral ultrasound studies, findings in one of the joints exemplified the overall result reported. Conclusions: Rheumatological musculoskeletal ultrasound has proven to be a useful decision-making technique, the greater the impact of which is seen the shorter the waiting time before it is performed.(AU)

RESUMEN

Alzheimer's disease (AD) involves a complex pathological process that evolves over years, and its etiology is understood as a classic example of gene-environment interaction. The notion that exposure to microbial organisms may play some role in AD pathology has been proposed and debated for decades. New evidence from model organisms and -omic studies, as well as epidemiological data from the recent COVID-19 pandemic and widespread use of vaccines, offers new insights into the "germ hypothesis" of AD. To review new evidence and identify key research questions, the Duke/University of North Carolina (Duke/UNC) Alzheimer's Disease Research Center hosted a virtual symposium and workshop: "New Approaches for Understanding the Potential Role of Microbes in Alzheimer's disease." Discussion centered around the antimicrobial protection hypothesis of amyloid accumulation, and other mechanisms by which microbes could influence AD pathology including immune cell activation, changes in blood-brain barrier, or direct neurotoxicity. This summary of proceedings reviews the content presented in the symposium and provides a summary of major topics and key questions discussed in the workshop.

RESUMEN

OBJECTIVE: To determine the effect of subclinical synovitis on the progression of joint disease in a cohort of patients with systemic lupus erythematosus over a mean follow-up of 10 years. METHODS: A longitudinal follow-up of 96 patients diagnosed with lupus was performed. All patients were considered clinically free of joint disease or with minimal joint impairment at baseline and were studied through ultrasound study of their dominant hand to assess the prevalence of subclinical synovitis. Now, over 10 years after we contacted them and reviewed their evolution to determine the impact of had or had not been diagnosed with subclinical synovitis in their current joint condition. RESULTS: Thirty-one of the 91 reached patients developed clinical progression in their joint manifestations (at least one ordinal degree of worsening). Of these, 23 (74,9%) had demonstrated subclinical synovitis at baseline. In the group of patients who did not progress clinically, 46 (76,6%) did not have this finding at the start of follow-up (p < .01, OR 9,44 95%CI 3,46-25,74). The patients in whom clinical progression was demonstrated had worse combined ultrasound scores than the rest of the patients: 6,41 SD 1,45 vs. 1,15 SD 0,97 (p < .01). CONCLUSIONS: The finding of subclinical synovitis in patients with systemic lupus erythematosus is associated with the development of joint disease progression both clinically and ultrasonographically.

RESUMEN

Objective: Health-related quality of life (HRQoL) is an important indicator of population health and can measure the impact of medical actions. The main objective of this study was to determine the HRQoL of patients with rheumatic diseases (RD) and compare it with that of the general population. Methods: Observational, cross-sectional, single-center study, with consecutive inclusion of outpatients over 18 years of age seen at a Rheumatology hospital-based outpatient clinic in Madrid. Sociodemographic, clinical variables and HRQoL were recorded. HRQoL was measured with the 5-dimension, 5-level EuroQoL (EQ-5D-5L), which includes the EQ-Index (0–1 scale) and a visual analog scale (VAS, 0–100 scale). A descriptive analysis and a comparison with the HRQoL of the Spanish general population were performed. Results: 1144 patients were included, 820 (71.68%) women, with a mean age of 56.1 years (range 18–95), of whom 241 (25.44%) were new patients. In patients with RD, the HRQoL measured with the EQ-Index and with the VAS, was 0.186 and 12 points lower, respectively, than in the general population. The decrease in HRQoL affected the 5 health dimensions, especially “pain/discomfort”, followed by “daily activities” and “mobility”. This reduction in HRQoL was observed in both men and women, and in all age ranges, although it was greater between 18 and 65 years of age. The reduction in HRQoL affected all RD subtypes, especially the “peripheral and axial mechanical pathology” and the “soft tissue pathology” group. Conclusions: Patients with rheumatic diseases report worse HRQoL when compared to the general population in all dimensions of HRQoL.(AU)


Objetivo: La calidad de vida relacionada con la salud (CVRS) se considera un indicador importante para valorar el estado de salud poblacional y medir el impacto de las actuaciones médicas. El principal objetivo de este estudio es conocer la CVRS de los pacientes con enfermedades reumáticas (RD, por sus siglas en inglés) y compararla con la población general. Métodos: Estudio observacional, transversal, unicéntrico, con inclusión consecutiva de pacientes ambulatorios mayores de 18 años atendidos en la consulta hospitalaria de reumatología. Se recogieron variables sociodemográficas, clínicas y CVRS medida con el EuroQoL de 5 dimensiones y 5 niveles (EQ-5D-5L) que incluye el EQ-Índex (escala 0-1) y una escala visual analógica (EVA, escala 0-100). Se realizó un análisis descriptico y una comparación con la población española según la Encuesta Nacional de Salud. Resultados: Se han incluido 1.144 pacientes, 820 (71,68%) mujeres, con edad media de 56,1 años (rango 18-95), de los que 241 (25,44%) eran pacientes nuevos. En los pacientes con RD, la CVRS medida con el EQ-Index y con la EVA, fue de 0,186 y 12 puntos menor, respectivamente, que en la población general. La CVRS afectó a las 5 dimensiones de salud, especialmente a «dolor/malestar», seguida de «actividades cotidianas» y «movilidad». Esta reducción de la CVRS se mantuvo tanto en varones y mujeres, y en todos los segmentos de edad, aunque fue mayor entre los 18 y 65 años. La reducción de CVRS afectó a todos los subtipos de RD, especialmente a la «Enfermedad mecánica periférica y axial» y al grupo de «Enfermedad de tejidos blandos». Conclusiones: Los pacientes con enfermedades reumáticas declaran peor CVRS en comparación a la población general en todas las dimensiones de la CVRS.(AU)

RESUMEN

OBJECTIVE: Health-related quality of life (HRQoL) is an important indicator of population health and can measure the impact of medical actions. The main objective of this study was to determine the HRQoL of patients with rheumatic diseases (RD) and compare it with that of the general population. METHODS: Observational, cross-sectional, single-center study, with consecutive inclusion of outpatients over 18 years of age seen at a Rheumatology hospital-based outpatient clinic in Madrid. Sociodemographic, clinical variables and HRQoL were recorded. HRQoL was measured with the 5-dimension, 5-level EuroQoL (EQ-5D-5L), which includes the EQ-Index (0-1 scale) and a visual analog scale (VAS, 0-100 scale). A descriptive analysis and a comparison with the HRQoL of the Spanish general population were performed. RESULTS: 1144 patients were included, 820 (71.68%) women, with a mean age of 56.1 years (range 18-95), of whom 241 (25.44%) were new patients. In patients with RD, the HRQoL measured with the EQ-Index and with the VAS, was 0.186 and 12 points lower, respectively, than in the general population. The decrease in HRQoL affected the 5 health dimensions, especially "pain/discomfort", followed by "daily activities" and "mobility". This reduction in HRQoL was observed in both men and women, and in all age ranges, although it was greater between 18 and 65 years of age. The reduction in HRQoL affected all RD subtypes, especially the "peripheral and axial mechanical pathology" and the "soft tissue pathology" group. CONCLUSIONS: Patients with rheumatic diseases report worse HRQoL when compared to the general population in all dimensions of HRQoL.
