Enamel fluorosis related with fluoride-containing water ingestion and urinary excretion in schoolchildren.

Background: Natural water sources are considered as the major environmental exposure of fluoride, resulting in increased prevalence of enamel fluorosis. This type of natural exposure should be permanently monitored to avoid the interactions with other non-natural fluoride sources. We evaluated the prevalence of enamel fluorosis in Colombian schoolchildren and its relationship with fluoride-containing water ingestion exposure dose and urinary fluoride excretion. Material and Methods: We included 923 schoolchildren aged 7-12 years residing in eight municipalities in Colombia. Sampling of consumption water was performed in major aquifers used for daily supply. Samples were collected in 98 polyethylene containers and refrigerated until analysis. Water and urine fluoride concentrations were measured using the fluoride selective electrode method. Enamel fluorosis was evaluated using Thylstrup and Ferjerskov Index (TFI). Demographic and anthropometric characteristics were assessed. Besides, other exposures to non-natural fluoride were also evaluated. Logistic regression was applied for multiple analyses. Results: The median fluoride concentration in water and urine samples was 10.5 mg/L and 0.63 mg/L respectively, with the highest value found in Algarrobo-Magdalena, and the lowest value found in Manzanares-Caldas. The overall prevalence of enamel fluorosis was 86.1%, being more frequent the mild codes with TFI-1 to TFI-2. The highest prevalence was found in Margarita-Bolívar and Manzanares-Caldas, and the most severe codes (TFI-5 to TFI-9) were detected in Manzanares-Caldas. The multiple analysis revealed water ingestion exposure dose, urinary excretion, involuntary intake of toothpaste, amount of table salt consumption and sex as significant factors (p< 0.001). Conclusions: The fluoride ingestion exposure dose and its subsequent urinary excretion could be used as estimators of past fluoride exposure, explaining the current prevalence of enamel fluorosis in Colombian schoolchildren. Key words:Fluoride, groundwater ingestion, enamel fluorosis, prevalence, severity.

Therapy for Chikungunya Arthritis: A Study of 133 Brazilian Patients.

Chikungunya fever is a global vector-borne viral disease. Patients with acute chikungunya are usually treated symptomatically. The arthritic phase may be self-limiting. However, many patients develop extremely disabling arthritis that does not improve after months. The aim of this study was to describe the treatment of chikungunya arthritis (CHIKA) patients. A medical records review was conducted in 133 CHIKA patients seen at a rheumatology practice. Patients were diagnosed by clinical criteria and confirmed by the presence of anti-chikungunya IgM. Patients were treated with methotrexate (20 mg/week) and/or leflunomide (20 mg/day) and dexamethasone (0-4 mg/day) for 4 weeks. At baseline visit and 4 weeks after treatment, Disease Activity Score 28 (DAS28) and pain (using a visual analog scale) were ascertained. Five months after the end of treatment, patients were contacted to assess pain, tender joint count, and swollen joint count. The mean age of patients was 58.6 ± 13.7 years, and 119 (85%) were female. After 4 weeks of treatment, mean (SD) DAS28-erythrocyte sedimentation rate (6.0 [1.2] versus 2.7 [1.0], P < 0.001) and pain (81.8 [19.2] to 13.3 [22.9], P < 0.001) scores significantly decreased. A total of 123 patients were contacted 5 months after the end of treatment. Pain score, tender joint count, and swollen joint count significantly declined after 4 weeks of treatment, and the response was sustained for 5 months. In this group of patients with CHIKA, 4-week treatment induced a rapid clinical improvement that was maintained 5 months after the end of therapy; however, the contribution of treatment to these outcomes is uncertain.

Short- and mid-term outcomes in systemic lupus erythematosus patients presenting with disease exacerbation after SARS-CoV-2 mRNA vaccination: A cohort study from Puerto Rico.

OBJECTIVE: To determine if SARS-CoV-2 mRNA vaccination has an impact on the clinical course of systemic lupus erythematosus (SLE). METHODS: Puerto Ricans with SLE who received mRNA COVID-19 vaccines were studied. Demographic parameters, clinical manifestations, disease activity (per Systemic Lupus Erythematosus Disease Activity Index (SLEDAI), disease damage (per Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index), emergency room visits, hospitalizations, and pharmacologic therapy were determined. Baseline variables (prior to vaccination) were compared between patients with and without exacerbation after SARS-CoV-2 vaccination. Among those with exacerbation, clinical outcomes were determined up to 1 year after vaccination. RESULTS: Of the entire cohort (n = 247), 14 (5.7%) had post-vaccination exacerbations. Photosensitivity, oral ulcers, anti-Ro antibodies, higher SLEDAI score, and corticosteroids exposure were associated with post-vaccination flares. Among those with post-vaccination flares, 10 (71.4%) had major organ involvement. No significant differences were observed for mean SLEDAI scores, emergency room visits, hospitalizations, disease damage, and exposure to immunosuppressive drugs before and after SARS-CoV-2 mRNA vaccination. At 12 months of follow-up, all patients were fully controlled without evidence of active disease. CONCLUSION: In our group of SLE patients, 5.7% had a disease flare after SARS-CoV-2 mRNA vaccination. Most had exacerbations involving major organs/systems. Mucocutaneous manifestations, anti-Ro antibodies, disease activity, and corticosteroids were associated with flares. Awareness of these factors and the possibility of a major lupus flare after vaccination with COVD-19 vaccines is critical to provide timely and effective therapy.

Association of Systemic Lupus International Collaborating Clinics Frailty Index With Damage in Systemic Lupus Erythematosus Patients: Results From a Multiethnic, Multicenter US Cohort of Patients With Lupus.

OBJECTIVE: To evaluate the association between the Systemic Lupus International Collaborating Clinics frailty index (SLICC-FI) and damage accrual in systemic lupus erythematosus (SLE) patients. METHODS: Patients from the multiethnic, multicenter LUpus in MInorities, NAture versus nurture (LUMINA) cohort were included. Damage was ascertained with the SLICC/American College of Rheumatology Damage Index (SDI) at last visit (range 0-51). The first visit in which the SLICC-FI score could be derived was considered as the baseline (range 0-1). Univariable and multivariable negative binomial regression models were performed to determine the association between the baseline SLICC-FI score (per 0.05 increase) and the change in the SDI score (difference between last and baseline SDI score), adjusted for sex, age at diagnosis, ethnicity, insurance, prednisone daily dose, and antimalarial and immunosuppressive drug use at baseline. Age and sex were included a priori in the multivariable model; the other variables were included if they reached P < 0.10 in the univariable models. RESULTS: Of the 503 patients included, 454 (90.3%) were female, with a mean ± SD age of 37.1 ± 12.5 years at diagnosis. The mean ± SD baseline SLICC-FI score was 0.26 ± 0.06. The mean ± SD baseline SDI score was 0.6 ± 1.0, and the mean ± SD change in the SDI score was 1.9 ± 2.2. Higher SLICC-FI scores at baseline (per 0.05 increase) were associated with greater damage accrual in the multivariable model after adjustment for possible confounders (incidence rate ratio 1.20 [95% confidence interval 1.08-1.33], P = 0.0015). CONCLUSION: The SLICC-FI is associated with damage accrual in SLE patients from a multiethnic cohort, supporting the importance of this index in the evaluation of SLE patients, combining several aspects of their disease.

Monarticular rheumatoid arthritis of the elbow.

Rheumatoid arthritis (RA) is a chronic autoimmune disease characterised by symmetric inflammatory polyarthritis. However, RA limited to a single joint is extremely rare. Here, we report a middle-aged woman who presented with insidious right elbow arthritis. She had no other peripheral joint pain, tenderness or swelling. She had high-positive anti-cyclic citrullinated peptide antibodies. An MRI of the right elbow showed capsular distension, joint effusion and bone marrow oedema. Synovial biopsy revealed hyperplasia with lymphoplasmacytic infiltrate consistent with RA. Therapy with methotrexate 7.5 mg orally weekly was effective to control her inflammatory arthritis. This case highlights the relevance of synovial tissue analysis for patients presenting with chronic inflammatory monarthritis when the cause is not clinically evident, and the importance of considering RA even in the absence of polyarticular involvement. Delayed diagnosis and treatment of inflammatory monarthritis can lead to joint destruction and disability.

New-Onset Systemic Lupus Erythematosus after mRNA SARS-CoV-2 Vaccination.

Systemic lupus erythematosus (SLE) is a multisystem autoimmune disease resulting from the interaction of genetic and environmental factors. In addition, some antiviral vaccines have been associated with the onset of SLE. Few cases of SLE occurring after SARS-CoV-2 mRNA have been reported. Herein, we report the case of a 27-year-old woman with type I diabetes mellitus and family history of SLE who presented with symmetric inflammatory polyarthritis of the proximal interphalangeal joints, metacarpophalangeal joints, wrists, knees, and ankles two weeks after receiving the second dose of the SARS-CoV-2 mRNA-1273 vaccine. Laboratory results revealed positive antinuclear, anti-dsDNA, anti-Ro, and anti-La/SSB antibodies and low C4 levels. She was initially treated with low-dose prednisone and hydroxychloroquine. Hydroxychloroquine was discontinued after she developed an urticarial rash. Subsequently, mycophenolate mofetil was added after she developed proteinuria. This case highlights the importance of considering the diagnosis of SLE in patients who present with inflammatory polyarthritis after COVID-19 vaccination.

Extensive Longitudinal Transverse Myelitis after Influenza A Virus Infection in a Patient with Systemic Lupus Erythematosus.

Transverse myelitis (TM) is a rare complication seen in 1-2% of patients with systemic lupus erythematosus (SLE). Viral infections may cause TM in these patients by causing a dysregulation of their immune system. We report a 30-year-old woman with SLE who had influenza A and a few days later developed urinary retention, bilateral lower extremity paralysis, upper extremity weakness, and optic nerve and macular edema. Magnetic resonance imaging showed C4-T12 hyperintense lesions consistent with TM. She was treated with intravenous methylprednisolone 1 g daily for 3 days and then 6 cycles of monthly intravenous cyclophosphamide. This treatment was followed by oral prednisone. She had a remarkable clinical response. Visual acuity improved to her baseline, and muscle strength almost fully recovered. Clinicians should be aware that viral infections, including influenza, may induce TM. This case highlights the importance of early recognition and prompt treatment with immunosuppressive drugs in such cases.

Isolated intestinal polyarteritis nodosa in an elderly patient.

Polyarteritis nodosa (PAN) is a necrotising systemic vasculitis involving medium-sized and small-sized vessels. PAN limited to a single organ is rare, particularly in the elderly population. Herein, we present a 73-year-old-woman who developed severe abdominal pain. Mesenteric angiography showed multifocal areas of segmental dilation and narrowing of the superior mesenteric, ileocolic and right colonic arteries. Exploratory laparotomy revealed multiple areas of necrosis of the jejunum for which resection was performed. Histopathological exam disclosed mesenteric vasculitis with fibrinoid necrosis of the arterial wall with leucocytic infiltrates and haemorrhages consistent with PAN. She was started on high-dose corticosteroids with an initial good response. However, 6 months later, she developed intestinal pseudo-obstruction for which oral cyclophosphamide was started. After 5 months of cyclophosphamide therapy, she remained stable without further relapses. Our case suggests that PAN should be considered in elderly patients presenting with abdominal pain even in the absence of systemic involvement.

Clinical Manifestations and Outcomes in Disease-Modifying Antirheumatic Drug-Naive Adult Patients with Chronic Chikungunya Arthritis.

Most studies on chronic chikungunya virus (CHIKV) arthritis include patients treated with disease-modifying antirheumatic drugs (DMARDs), likely altering the expression of clinical manifestations and outcome. Therefore, we sought to evaluate the clinical features and correlates in DMARD-naive patients with chronic CHIKV arthritis. We conducted a case-control study in adult patients with serologically confirmed CHIKV infection in Puerto Rico. Demographic features, clinical manifestations, comorbidities, disease activity (per Clinical Disease Activity Index [CDAI]), functional status (per Health Assessment Questionnaire Disability Index [HAQ-DI]), and pharmacologic treatment were ascertained. Patients with and without chronic CHIKV arthritis were compared. Furthermore, a sub-analysis was performed among patients with chronic CHIKV who presented with mild disease activity versus moderate-to-high disease activity at study visit. In total, 61 patients were studied; 33 patients had chronic arthritis and 28 had resolved arthritis. Patients with chronic arthritis had significantly more diabetes mellitus, chronic back pain, and fever, tiredness, and myalgias on the acute phase. The mean (SD) HAQ score was 0.95 (0.56), and 57.6% had moderate-to-high disease activity. Patients with moderate-to-high disease activity had higher scores in overall HAQ-DI and HAQ-DI categories (dressing and grooming, arising, hygiene, reaching, and activities) than in those with mild activity. In conclusion, in this group of DMARD-naive patients with chronic CHIKV arthritis, nearly 58% had moderate-to-high disease activity and had substantial functional disability. Diabetes mellitus, chronic back pain, and some manifestations on acute infection were associated with chronic CHIKV arthritis.

Achievement of the 2019 European Alliance of Associations for Rheumatology/American College of Rheumatology Criteria for Systemic Lupus Erythematosus and Amount of Damage Accrual: Results From a Multiethnic Multicenter Cohort.

OBJECTIVE: To determine the difference in outcomes in patients who achieved or did not achieve the 2019 European Alliance of Associations for Rheumatology (EULAR)/American College of Rheumatology (ACR) criteria. METHODS: Patients from the LUpus in MInorities, NAture versus nurture (LUMINA) cohort were included. For these analyses, we compared those patients who achieved the 2019 EULAR/ACR criteria any time during follow-up to those who did not. The predefined outcomes were the last Systemic Lupus International Collaborating Clinics/ACR Damage Index (SDI) scores and survival. Univariable and multivariable negative binomial regression models were performed; adjustment models were based on a forward selection process. RESULTS: In total, 98 of 640 patients never achieved the 2019 EULAR/ACR criteria. There was no difference in mean baseline SDI score among the patients who did not achieve the criteria compared to those who did. Conversely, the mean ± SD SDI score at last visit was lower for those who never achieved the criteria (1.2 ± 1.7 versus 2.0 ± 2.3, P = 0.0004). In the final adjusted model, the SDI score at last visit was 31% lower for those who never achieved the criteria (P = 0.0077). These patients were also more likely to survive, but this was not statistically significant. CONCLUSION: In our cohort, patients who did not achieve the 2019 EULAR/ACR criteria accrued less damage, suggesting that these criteria could allow us to identify a subset of patients with more severe disease than allowed by previous criteria.

Incident arterial vascular events in a cohort of Puerto Ricans with rheumatoid arthritis.

OBJECTIVE: The increased morbidity and mortality associated with cardiovascular events in patients with rheumatoid arthritis has been linked to traditional and nontraditional factors. However, these factors vary among different ethnicities. Few studies have described these features in Hispanic populations. Thus, we determined the clinical correlates of arterial vascular events in Hispanics from Puerto Rico. METHODS: A cross-sectional study was performed in a cohort of 405 Puerto Ricans with rheumatoid arthritis. Demographic parameters, health-related behaviors, clinical manifestations, disease activity (per Disease Activity Score 28), functional status (per Health Assessment Questionnaire), comorbidities, and pharmacotherapy were compared in patients with and without incident arterial vascular events. The latter was defined as the occurrence of myocardial infarction, angina pectoris, vascular procedures for coronary artery disease, stroke, or peripheral artery disease. Study groups were analyzed using bivariate and multivariate analyses. RESULTS: Of the total study population, 87.2% were woman. The mean age at study visit was 56.1 ± 13.9 years, and the mean disease duration was 15.0 ± 13.2 years. Arterial vascular events occurred in 43 patients (10.6%). In the multivariate analysis adjusted for age and sex, arterial hypertension, dyslipidemia, metabolic syndrome, extra-articular manifestations, higher Health Assessment Questionnaire score, and number of hospitalizations were associated with arterial cardiovascular events. CONCLUSION: In this cohort of Puerto Ricans with rheumatoid arthritis, traditional and nontraditional factors, particularly extra-articular manifestations and functional disability, were associated with arterial vascular events. Awareness of these associations may help to implement clinical strategies in this group of rheumatoid arthritis patients at risk of arterial vascular events.

Characterization of a subset of patients with primary Sjögren's syndrome initially presenting with C3 or C4 hypocomplementemia.

OBJECTIVE: This study aimed to determine the association of C3 and C4 hypocomplementemia at the diagnosis of primary Sjögren's syndrome (pSS) with clinical manifestations, disease activity, and disease damage. METHODS: A cross-sectional study was conducted in 94 Puerto Ricans with pSS. Patients were aged ≥21 years and met the 2012 American College of Rheumatology Classification Criteria for pSS. Demographic characteristics, health-related features, cumulative extraglandular manifestations, serologic tests at pSS diagnosis, comorbidities, disease activity (per European League Against Rheumatism Sjögren's Syndrome Disease Activity Index [ESSDAI]), disease damage (per Sjögren's Syndrome Disease Damage Index [SSDDI]), and pharmacologic therapy were determined. Serum C3 and C4 levels were measured at pSS diagnosis by immunoturbidimetry. Patients with and without hypocomplementemia were analyzed using bivariate and multivariate logistic regression analyses adjusted for age, sex, and disease duration. RESULTS: The mean age and disease duration of the study population were 52.4±12.4 years and 5.9±4.8 years, respectively; of the total study population, 94% were female. C3 and C4 hypocomplementemia were observed in 9.6% and 13.8% of the patients, respectively. In the multivariate analysis, C3 hypocomplementemia was associated with leukocytoclastic vasculitis, interstitial lung disease, higher SSDDI score, and exposure to rituximab. C4 hypocomplementemia was associated with leukocytoclastic vasculitis, interstitial lung disease, and higher ESSDAI and SSDDI scores. CONCLUSION: In this population of patients with pSS, low C3 and C4 levels at diagnosis were associated with extraglandular manifestations such as vasculitis and interstitial lung disease, as well as disease activity and damage accrual. These results suggest that complements C3 and C4 have clinical and prognostic value in patients with pSS.

Clinical impact of hydroxychloroquine dose adjustment according to the American Academy of Ophthalmology guidelines in systemic lupus erythematosus.

OBJECTIVE: The American Academy of Ophthalmology recommends a maximum hydroxychloroquine (HCQ) dose of ≤5.0 mg/kg/day to reduce the risk of HCQ-induced retinopathy. To determine if this dose adjustment would have an impact on the clinical course of SLE, we compared outcome measures in a cohort of patients with SLE before and after adjusting HCQ dose. METHODS: Sixty Puerto Ricans with SLE (per 1997 American College of Rheumatology criteria) treated with HCQ who were changed to HCQ ≤5.0 mg/kg/day were studied. Visits were ascertained every 6 months for 2 years before and 2 years after HCQ dose adjustment (baseline visit). Disease activity (per Systemic Lupus Erythematosus Disease Activity Index (SLEDAI)), SLE exacerbations, emergency room visits, hospitalisations, disease damage (per Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index), corticosteroids exposure, prednisone dose and immunosuppressive drugs exposure were determined before and after HCQ dose change. RESULTS: At baseline visit, the mean age was 43.8±15.1 years. All patients were women. The mean disease duration was 13.8±9.1 years. After HCQ dose adjustment, patients required a lower prednisone dose when compared with visits before HCQ dose reduction. No significant differences were observed for mean SLEDAI scores, lupus exacerbations, emergency room visits, hospitalisations, disease damage and exposure to immunosuppressive drugs before and after HCQ dose adjustment. CONCLUSIONS: This study suggests that adjustment of daily HCQ dose to ≤5.0 mg/kg/day of actual body weight does not have a significant impact on the short-term and mid-term outcomes in this group of patients with SLE.

Applying the 2019 EULAR/ACR lupus criteria to patients from an established cohort: a Latin American perspective.

OBJECTIVE: To evaluate the performance of the 2019 European League Against Rheumatism (EULAR)/American College of Rheumatology (ACR) systemic lupus erythematosus (SLE) criteria in terms of earlier patients' classification in comparison to the 1982/1997 ACR or the 2012 Systemic Lupus International Collaborating Clinics (SLICC) criteria. MATERIALS AND METHODS: Patients from a Latin America, multiethnic, multicentre cohort, where SLE was defined using the physicians' diagnosis, were included. To calculate the sensitivity of the 2019 EULAR/ACR criteria, the 1982/1997 ACR criteria were considered the gold standard. Additionally, comparison of the 1982/1997 ACR criteria and the 2012 SLICC criteria with the 2019 EULAR/ACR criteria was performed. RESULTS: The sensitivity of the 2019 EULAR/ACR criteria when compared with the 1982/1997 ACR criteria as the gold standard was 91.3%. This new set of criteria allowed an earlier SLE patient classification in 7.4% (mean 0.67 years) and 0.6% (mean 1.47 years) than the 1982/1997 ACR and the 2012 SLICC criteria, respectively. Patients accruing the 2019 EULAR/ACR earlier than the 1982/1997 ACR criteria were more likely to have high anti-dsDNA titres; those accruing them later were less likely to have mucocutaneous and joint manifestations; this was not observed when comparing them with the 2012 SLICC criteria. CONCLUSIONS: The 2019 EULAR/ACR criteria classified earlier only a small proportion of Latin America patients than with the two other criteria sets in real-life clinical practice scenarios. Further studies in different patient populations are needed before these new criteria are adopted worldwide.

Factors Associated With Disease Damage in Puerto Ricans With Primary Sjögren Syndrome.

OBJECTIVE: The aim of this study was to determine the association of demographic parameters, clinical manifestations, disease activity, and pharmacologic therapy with disease damage in a group of Puerto Ricans with primary Sjögren syndrome (pSS). METHODS: A cross-sectional study was conducted in 100 Hispanics of Puerto Rico with pSS. Patients were 21 years or older and fulfilled the 2012 American College of Rheumatology classification criteria for pSS. Demographic factors, lifestyle behaviors, extraglandular manifestations, serologic tests, comorbidities, pharmacologic therapy, disease activity (per European League Against Rheumatism Sjögren Syndrome Disease Activity Index), and disease damage (per Sjögren Syndrome Disease Damage Index [SSDDI]) were assessed. Patients with disease damage (SSDDI ≥1) and without damage (SSDDI = 0) were compared using bivariate analysis and multivariate regression analysis adjusted for age, sex, and disease duration. RESULTS: The mean age of patients was 52.8 years; 94% were women. The mean disease duration was 5.9 years. Thirty-nine patients had disease damage. Disease damage was mainly attributed to pulmonary fibrosis and peripheral neuropathy. In the bivariate analysis, disease damage was associated with low C3 and C4, coronary artery disease, infections, and higher activity index and was more frequently treated corticosteroids and azathioprine. In the multivariate analysis, low C3, disease activity, and corticosteroid exposure retained significance. CONCLUSIONS: In this population of Puerto Ricans with pSS, C3 and C4 hypocomplementemia, coronary artery disease, infections, and exposure to corticosteroids and azathioprine were associated with damage accrual. Clinicians should be aware of these factors to identify those who may require close follow-up and early therapeutic intervention.

Time in remission and low disease activity state (LDAS) are associated with a better quality of life in patients with systemic lupus erythematosus: results from LUMINA (LXXIX), a multiethnic, multicentre US cohort.

Aims: To determine whether the proportion of time systemic lupus erythematosus patients achieve remission/low disease activity state (LDAS) is associated with a better quality of life (QoL). Patients and methods: Patients from a well-established multiethnic, multicentre US cohort were included: remission: Systemic Lupus Activity Measure (SLAM) score=0, prednisone≤5 mg/day and no immunosuppressants); LDAS not in remission, SLAM score≤3, prednisone≤7.5 mg/day, no immunosuppressants; the combined proportion of time patients were in these states was the independent variable. The endpoints were the Physical and Mental Components Summary measures (PCS and MCS, respectively) and the individual subscales of the Short Form (SF)-36 at the last visit. Linear regression was used to estimate the association between the proportion of follow-up time in remission/LDAS and the SF-36 measures with and without adjustment for possible confounders. Results: Four hundred and eighty-three patients were included. The per cent of time on remission/LDAS was associated with better QoL after adjusting for potential confounders; for the PCS the parameter estimate was 9.47 (p<0.0001), for the MCS 5.89 (p=0.0027), and for the subscales they ranged between 7.51 (p=0.0495) for mental health and 31.79 (p<0.0001) for role physical. Conclusions: The per cent of time lupus patients stay on remission/LDAS is associated with a better QoL as measured by SF-36.

Calidad de vida de pacientes con discapacidad transitoria o permanente en ortopedia y traumatología / Life quality in patients whith temporary or permanent disabilities in orthopedics and traumatology

Introducción: Según la Organización de la salud (OMS), calidad de vida es la percepción que un individuo tiene de su lugar en la existencia, en el contexto de la cultura y del sistema de valores en los que vive y en relación con sus objetivos, expectativas, normas e inquietudes. La escala GENCAT es una encuesta autoadministrada, basada en un modelo multidimensional que evalúa ocho dimensiones o dominios que cuando se toman en conjunto constituyen el concepto de calidad de vida. Objetivos: Describir la calidad de vida de los pacientes con discapacidad transitoria o permanente del Hospital Interzonal General (H.I.G) "Dr. José Penna" de Bahía Blanca, que se atendieron en el Servicio de Ortopedia y Traumatología, en un periodo de 3 meses. Materiales y Métodos: Estudio de corte trasversal en 66 pacientes con discapacidad transitoria o permanente que concurrieron al Servicio de Ortopedia y Traumatología del H.I.G "Dr. José Penna". Recolección prospectiva utilizando la escala GENCAT (01/07/18-01/10/18). Resultados: En el análisis de los dominios que afectan la calidad de vida se evidencia que el Dominio de Autodeterminación es el menos afectado (percentil 79%), siendo el más afectado es Dominio el Físico (percentil 25%). Dando un resultado final para calidad de vida en el percentil 15. Conclusiones: Se pudo evaluar y demostrar de qué manera una patología Ortopédica o Traumatológica influye en la vida de los pacientes, no sólo en la parte física sino también en la parte social, laboral y personal.

Introdution: According to the World Health Organization (WHO), quality of life is the perception that an individual has of his/her place in the world, in the context of the culture and the value system in which he/she lives and in relation to his/her objectives, expectations, standards, and concerns. GENCAT is a self-administered survey, based on a multi-dimensional model that assesses eight dimensions or domains that constitute the concept of quality of life when taken as a whole. Objectives: To describe the quality of life of patients with temporary or permanent disabilities at Hospital H.I.G "Dr. José Penna", Bahía Blanca, Orthopedics and Traumatology Service in a period of 3 months. Materials and Methods: cross-sectional study of 66 patients enrolled in the survey that presented temporary or permanent disabilities. Prospective data collection from July 1, 2018 to October 1, 2018 at Hospital H.I.G "Dr. José Penna", Bahía Blanca, Orthopedics and Traumatology Service using the GENCAT scale. Results: In the domain analysis that affects quality of life, it is evident that self-determination is the least affected domain (79% percentile) and the physical domain is the most affected one (25% percentile). A final result for quality of life in percentile 15 was obtained. Conclusion: ithas been evaluated and demonstrated that the influence of an orthopedic pathology or trauma in the life of a patient, has an impact not only in the physical but also in the social, labor, and personal life of an individual.

Association of soluble TREM-like transcript-1 with clinical features and patient reported outcomes in systemic lupus erythematosus.

OBJECTIVE: The soluble triggering receptor expressed on myeloid cells (TREM-1)-like transcript 1 (sTLT-1) has a modulatory effect on the activation of TREM-1. We compared plasma sTLT-1 levels between patients with systemic lupus erythematosus (SLE) and healthy individuals and determined the association between sTLT-1 levels and clinical features and patient-reported outcomes (PROs) among patients with lupus. METHODS: An unmatched case-control study was conducted in 46 patients with SLE and 28 healthy subjects. sTLT-1 plasma levels were determined using enzyme-linked immunosorbent assay. Demographic factors, SLE manifestations, comorbidities, pharmacologic profile, disease activity (per SLAM-R), damage accrual, and PROs (as per Lupus Patient-Reported Outcome [LupusPRO]) were studied. RESULTS: Patients with SLE were found to have lower sTLT-1 levels compared with healthy individuals (9.0±7.2 vs. 18.6±22.3 pg/mL, p=0.008). Among patients with SLE, higher sTLT-1 levels were found in those taking corticosteroids (11.1±8.8 vs. 6.9±4.6 pg/mL, p=0.014). Significant correlations were found for the cognition (r=-0.442, p=0.027) and desires/goals (r=0.435, p=0.030) domains of LupusPRO. A tendency was observed between sTLT-1 levels and the SLAM-R (r=-0.278, p=0.064) and the lupus symptoms (r=-0.388, p=0.055) and physical health (r=-0.382, p=0.060) domains of LupusPRO. CONCLUSION: Compared with healthy individuals, sTLT-1 levels were significantly lower in patients with SLE. Among patients with SLE, correlations were observed for some domains of LupusPRO. Given that sTLT-1 has anti-inflammatory properties, the deficiency of this protein could play an important role in the pathogenesis of SLE.
