A Mixed-Methods Systematic Review on Syndemics in Rheumatology.

OBJECTIVE: We aimed to assess the use of framework and corresponding methodology to document syndemics and its impact in rheumatic and musculoskeletal diseases (RMDs). METHODS: Using a mixed-methods systematic review, studies using the syndemic framework approach for RMDs were identified and published from January 2003 to January 2021. The Joanna Briggs Institute, Cochrane Collaboration, and PRISMA guidelines were followed to search, retrieve, revise, and analyze. RESULTS: A total of 658 potential articles were identified, but only 10 were initially eligible. After a full-text review, 4 were included. Following a full-text review, 2 quantitative, 1 qualitative, and 1 mixed-methods study were included. In the first, network analysis found that RMDs were associated with comorbidities, unhealthy habits, low educational level, living in rural areas, socioeconomic conditions, and health inequality in indigenous communities. In the second, SSEM and cluster analysis demonstrated an association between low back pain and factors, such as comorbidities and indigenous status, among others, in urban/rural communities. The qualitative study examined 3 fishing family generations and reported less syndemic vulnerability. The mixed-methods study focused on osteoarthritis with multimorbidities in African American population, where lack of education added to worsening outcomes. CONCLUSIONS: Even though the insights syndemic studies have given to other areas, its use in rheumatology is scarce. The complexity of the clinical and social determinants related to RMDs makes it necessary to conduct further studies from a syndemic perspective.

Perception of risk and impact of the COVID-19 pandemic on patients with rheumatic diseases: a case-control study.

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.

Efficacy and safety of ultrasound-guided internal jugular vein catheterization in low birth weight newborn.

BACKGROUND: Central venous catheterization is not the first choice of vascular access in neonates. Success depends on the size of the vessel and the skill of the health professional performing the procedure. The internal jugular vein provides a predictable path for central venous cannulation, although it is more difficult to cannulate infants than adults and even more difficult in smaller newborns. METHODS: We conducted a prospective study in 100 newborns, in which a 4 Fr ultrasound-guided central venous catheter was placed in the right internal jugular vein (RIJV). The study population was low birth weight (LBW) newborns <2500g, very low birth weight (VLBW) newborns <1500g and extremely low birth weight (ELBW) newborns <1000g. RESULTS: There were 53% female patients, mean gestational age was 31weeks, mean weight 1352g and the CVC was placed at a mean of 12days of extrauterine life. Birth weight distribution was 39% LBW; 33% VLBW and 28% ELBW. A mean of two (1-8) attempts were necessary with a procedure duration of 16.8 (10-40) minutes. Success of RIJV catheterization was 94%. One attempt was necessary in 50% and up to 5 attempts in 95.7%. Success by weight was VLBW, 97.2%; ELBW, 92.9%; LBW, 91.7%. A venous hematoma occurred in 5% of cases. CONCLUSIONS: Ultrasound-guided RIJV cannulation with real-time visualization to gain access to the central venous circulation in low birth weight newborns is effective and safe.

Cross-cultural validation of the paediatric Gait, Arms, Legs, Spine (pGALS) tool for the screening of musculoskeletal disorders in Mexican children.

The aim of this study was to validate the paediatric Gait, Arms, Legs, Spine (pGALS) tool for Mexican Spanish to screen Mexican paediatric population for musculoskeletal (MSK) disorders. A cross-sectional study was performed in the Paediatric Hospital of the Mexican Social Security Institute in Guadalajara, Jalisco. The validation included children and adolescents aged 6-16 years, 87 patients with musculoskeletal disorders and 88 controls without musculoskeletal disorders. The cross-cultural validation followed the current published guidelines. The average pGALS administration time was 2.9 min (SD 0.54). The internal consistency score (Cronbach's α) was 0.90 (0.89 for inflammatory and 0.77 for non-inflammatory disorders) for MSK disorders, with a sensitivity of 97 % (95 % CI 92-99 %), a specificity of 93 % (95 % CI 86-97 %), a LR+ of 14.3, and a ROC curve of 0.95 (95 % CI 0.92-0.98 %). The inflammatory disorders group had a sensitivity of 97 % (95 % CI 86-99 %), a specificity of 93 % (95 % CI 86-97 %), a LR+ of 14.2, and a ROC curve of 0.95 % (95 % CI 0.91-0.99 %). The non-inflammatory disorders group had a sensitivity of 98 % (95 % CI 89-99 %), a specificity of 93 % (95 % CI 86-97 %), and a LR+ of 14.37, with a ROC curve of 0.95 % (95 % CI 0.92-0.98 %). pGALS is a valid screening tool, fast, easy to administer, and useful for detecting musculoskeletal disorders in Mexican children and adolescents.

Coping strategies for health and daily-life stressors in patients with rheumatoid arthritis, ankylosing spondylitis, and gout: STROBE-compliant article.

This article aims to identify the strategies for coping with health and daily-life stressors of Mexican patients with chronic rheumatic disease. We analyzed the baseline data of a cohort of patients with rheumatoid arthritis (RA), ankylosing spondylitis (AS), and gout. Their strategies for coping were identified with a validated questionnaire. Comparisons between health and daily-life stressors and between the 3 clinical conditions were made. With regression analyses, we determined the contribution of individual, socioeconomic, educational, and health-related quality-of-life variables to health status and coping strategy. We identified several predominant coping strategies in response to daily-life and health stressors in 261 patients with RA, 226 with AS, and 206 with gout. Evasive and reappraisal strategies were predominant when patients cope with health stressors; emotional/negative and evasive strategies predominated when coping with daily-life stressors. There was a significant association between the evasive pattern and the low short-form health survey (SF-36) scores and health stressors across the 3 diseases. Besides some differences between diagnoses, the most important finding was the predominance of the evasive strategy and its association with low SF-36 score and high level of pain in patients with gout. Patients with rheumatic diseases cope in different ways when confronted with health and daily-life stressors. The strategy of coping differs across diagnoses; emotional/negative and evasive strategies are associated with poor health-related quality of life. The identification of the coping strategies could result in the design of psychosocial interventions to improve self-management.

Vascular assessment of the right internal jugular vein in low birth weight newborns.

OBJECTIVE: To determine the dimensions and depth of the right internal jugular vein (RIJV) in low birth weight newborns by ultrasound and assess the differences in weight and determine the relationship of the vein with the carotid artery. METHOD: We performed a vascular assessment of the RIJV in 100 low birth weight newborns. The subjects were divided into three groups, low birth weight (LBW) newborns, <2500 g; very low birth weight (VLBW) newborns, <1500 g; and extremely low birth weight (ELBW) newborns <1000 g. RESULTS: Of the newborns, 39% had LBW, 33% had VLBW, and 28% had ELBW. The medians were gestational age 31 weeks, weight 1300 g, anteroposterior diameter of the RIJV 2.2 mm, and the distance from the skin-RIJV 3.6 mm. In LBW newborns, the median anteroposterior diameter of RIJV was 2.7 mm; in LBW newborns 2.2; in ELBW newborns 1.9 (p < 0.001); the median distance from skin to RIJV for LBW newborns was 4.1 mm; for VLBW newborns, 3.6 and for ELBW newborns 2.9 (p < 0.01); differences that were statistically significant. CONCLUSIONS: In low birth weight newborns, the diameter and depth of the RIJV is directly proportional to the weight of the subjects studied.

Catastrophic health expenses and impoverishment of households of patients with rheumatoid arthritis

Antecedentes. El costo de ciertas enfermedades puede dar lugar a gastos catastróficos y el empobrecimiento de las familias sin apoyo financiero por los organismos del Estado y otros. Objetivo. Determinar el impacto socioeconómico de la artritis reumatoide (AR) sobre costos en el contexto de los gastos catastróficos y el empobrecimiento. Pacientes y métodos. Se trata de una cohorte anidada en un estudio transversal y multicéntrico sobre el costo de la AR en los hogares mexicanos con cobertura parcial, completa o privado de salud. Los gastos catastróficos se definieron como aquellos que ocupaban > 30% del ingreso total del hogar. Empobrecimiento se definió como los hogares que no podían pagar la canasta básica de alimentos de México (CBA). Resultados. Se incluyeron 262 pacientes con un ingreso familiar promedio mensual (dólares americanos) de $ 376 (0-18,890.63). En total, el 50,8%, 35,5% y 13,7% de los pacientes tenían cobertura médica parcial, completa o privado, respectivamente. El costo anual de la AR fue de $ 5,534.8 por paciente (65% los costos directos, el 35% indirecto).La AR generó gastos catastróficos en el 46,9% de los hogares, que en el análisis de regresión logística se asociaron significativamente con el tipo de cobertura de salud (OR 2,7, IC 95% 1.6 a 4.7) y la duración de la enfermedad (OR 1,024, IC del 95% 1.002-1,046). El empobrecimiento se produjo en el 66,8% de los hogares y se asoció con gastos catastróficos (OR 3,6, IC 95% 1.04 a 14.1), los altos puntajes del cuestionario de Evaluación de Salud (OR 4,84 IC 95%: 1,01 a 23,3), y el nivel socioeconómico bajo (OR 4.66, IC 95%: 1.37-15.87). Conclusión. El costo de la AR en los hogares mexicanos, en particular los que no tienen cobertura de salud completa lleva a los gastos catastróficos y el empobrecimiento. Estos hallazgos podrían ser los mismo en los países con sistemas de salud fragmentados (AU)

Background: The cost of certain diseases may lead to catastrophic expenses and impoverishment of households without full financial support by the state and other organizations. Objective: To determine the socioeconomic impact of the rheumatoid arthritis (RA) cost in the context of catastrophic expenses and impoverishment. Patients and methods: This is a cohort-nested cross-sectional multicenter study on the cost of RA in Mexican households with partial, full, or private health care coverage. Catastrophic expenses referred to health expenses totaling >30% of the total household income. Impoverishment defined those households that could not afford the Mexican basic food basket (BFB). Results: We included 262 patients with a mean monthly household income (US dollars) of $376 (0-18,890.63). In all, 50.8%, 35.5%, and 13.7% of the patients had partial, full, or private health care coverage, respectively. RA annual cost was $ 4653.0 per patient (65% direct cost, 35% indirect). RA cost caused catastrophic expenses in 46.9% of households, which in the logistic regression analysis were significantly associated with the type of health care coverage (OR 2.7, 95%CI 1.6-4.7) and disease duration (OR 1.024, 95%CI 1.002-1.046). Impoverishment occurred in 66.8% of households and was associated with catastrophic expenses (OR 3.6, 95%CI 1.04-14.1), high health assessment questionnaire scores (OR 4.84 95%CI 1.01-23.3), and low socioeconomic level (OR 4.66, 95%CI 1.37-15.87). Conclusion: The cost of RA in Mexican households, particularly those lacking full health coverage leads to catastrophic expenses and impoverishment. These findings could be the same in countries with fragmented health care systems (AU)

[Comparative study of direct cost between open and laparoscopic cholecystectomy]. / Costos directos de colecistectomías abierta y laparoscópica.

OBJECTIVE: to compare the direct cost of open cholecystectomy (OCL) with laparoscopic cholecystectomy (LCL), using a microcosting approach. METHODS: in patients who underwent cholecystectomy (C) in the Hospital General de Mexico, we collected patient age and sex, time in the operative room (OR), anesthesia and surgical procedure; health personal (HP) involved; materials (M) and medications consumed; medical instruments (MI) and medical equipment (ME) used. RESULTS: there were 355 patients operated by C, were 248 included, 94 with CAB and 74 with CLP. CAB surgical time was longer than CLP (102 versus 82, p<0.00.1); CLP had a higher use of materials intraoperative ($5 329 versus $1 403, p<0.001). There are no differences in: cost for HP, MI and ME. The total direct cost was $7238 (US$615) for CAB and $12 507 (US$1 063) for CLP (p <0.001) at 11.76 Mexican pesos per dollar. CONCLUSIONS: the difference in costs between OCL and LCL is primarily explained by the cost of lab exams which represent 79% of the M cost for CLP.

Diagnosis of chronic gout: evaluating the american college of rheumatology proposal, European league against rheumatism recommendations, and clinical judgment.

OBJECTIVE: Observation of monosodium urate (MSU) crystal is the gold standard for diagnosis of gout, but is rarely performed in daily clinical practice, and diagnosis is based on clinical judgment. Our aim was to identify clinical and paraclinical data included in the European League Against Rheumatism recommendations (EULARr) and American College of Rheumatology proposed criteria (ACRp) for diagnosis of gout in patients with chronic gout according to their attending rheumatologists. METHODS: This cross-sectional and multicenter study included consecutive patients from outpatient clinics with a diagnosis of gout by their attending rheumatologists according to their expertise. The frequency of each item from the ACRp and EULARr was determined. Possible combinations of the items that were frequent, clinically relevant, and simple to evaluate in daily practice were determined. RESULTS: We studied 549 patients (96% men), mean age 50 +/- 14 years. Analysis of MSU crystals was performed in 15%. We selected 7 clinical criteria and 1 laboratory measure because of their frequency, importance, and simplicity to obtain: current or past history of: > 1 attack of acute arthritis (93%); mono or oligoarthritis attacks (74%); rapid progression of pain and swelling (< 24 hours; 74%); podagra (70%); erythema (56%); unilateral tarsitis (33%); tophi (52%); and hyperuricemia (93%). The chronic gout diagnosis (CGD) proposal comprised >or= 4/8 of these; 88% of patients had the criteria of the CGD proposal while 75% had 6/11 ACRp criteria (p = 0.001). When analysis of MSU crystals was added, 90.1% (CGD) and 83.9% (ACRp) met the criteria (p = 0.004). CONCLUSION: Current or past history of >or= 4/8 CGD parameters is highly suggestive of chronic gout.

Early hospital discharge and early puerperal complications.

OBJECTIVE: To evaluate the association between time of postpartum discharge and symptoms indicative of complications during the first postpartum week. MATERIALS AND METHODS: Women with vaginal delivery at a Mexico City public hospital, without complications before the hospital discharge, were interviewed seven days after delivery. Time of postpartum discharge was classified as early (<24 hours) or late (>25 hours). The dependent variable was defined as the occurrence and severity of puerperal complication symptoms. RESULTS: Out of 303 women, 208 (68%) were discharged early. However, women with early discharge and satisfactory prenatal care had lower odds of presenting symptoms in early puerperium than women without early discharge and inadequate prenatal care (OR 0.36; 95% confidence intervals = 0.17-0.76). CONCLUSIONS: There was no association between early discharge and symptoms of complications during the first postpartum week; the odds of complications were lower for mothers with early discharge and satisfactory prenatal care.

OBJETIVO:Evaluar la asociación entre el tiempo de egreso posparto y las posibles complicaciones en el puerperio mediato. MATERIAL Y MÉTODOS:Mujeres con parto vaginal atendidas en un hospital público de la Ciudad de México, sin complicaciones antes del egreso hospitalario, fueron entrevistadas a los siete días de egreso. La variable dependiente fue la ocurrencia y severidad de complicaciones. Se calcularon media y desviación estándar para las variables continuas, y proporciones para las categóricas. Las variables relacionadas con egreso temprano en el análisis bivariado (con p<0.15) fueron incluidas en un modelo de regresión logística. RESULTADOS:Se analizó información de 303 partos, de los cuales 208 (68%) tuvieron egreso temprano posparto. Las mujeres que fueron egresadas en forma temprana con un control prenatal adecuado reportaron menos síntomas de complicaciones en el puerperio mediato (RM= 0.36; IC 95% = 0.17-0.76). CONCLUSIONES:Aunque no se encontró asociación entre el egreso temprano y los síntomas de complicaciones durante la primera semana del posparto, el riesgo de complicaciones fue menor en mujeres con egreso temprano y con cuidado prenatal adecuado, comparadas con las mujeres que presentaron egreso tardío sin control prenatal.

[Social costs of the most common inflammatory rheumatic diseases in Mexico from the patient's perspective]. / El costo de las principales enfermedades reumáticas inflamatorias desde la perspectiva del paciente en México.

OBJECTIVE: To estimate the social costs of rheumatoid arthritis (RA), ankylosing spondylitis (AS), and gout from the patient's perspective. METHODS: We carried out a cross-sectional analysis of the cost and resource utilization of 690 RA, AS, and gout patients from 10 medical centers and private facilities in five cities of Mexico. The information was obtained from the baseline of a dynamic cohort. We estimated out-of-pocket expenses, institutional direct costs, and direct medical costs. RESULTS: The mean (SD) annual out-of-pocket expense (USD) was $610.0 ($302.2) for RA, $578.6 ($220.5) for AS, and $245.3 ($124.0) for gout. Figures correspond to 15%, 9.6%, and 2.5% of the family income. They also represented 26.1%, 25.3%, and 24.4% of the total annual cost per RA, AS, and gout patients, respectively. The expected direct institutional patient/year costs were 1,724.2 for RA, $1,710.8 for AS, and $760.7 for gout. The total patient annual costs were $2,334.3 for RA, $2,289.4 for AS, and $1,006.1 for gout. Most out-of-pocket expenses were used to purchase drugs, pay for laboratory tests, imaging studies, and alternative therapies. CONCLUSIONS: From the patient's perspective, the cost of RA, AS, and gout represents 25% of direct medical costs. The cost of RA is higher than that for AS and gout.

Métodos: Análisis transversal de los costos y utilización de recursos de 690 pacientes con AR, EA y gota, de 10 departamentos de centros hospitalarios y consultorios privados de cinco ciudades del país, al momento de ser incluidos en una cohorte dinámica. Se incluye una estimación de los gastos de bolsillo, los costos médicos directos institucionales y el costo médico directo real. Resultados: El gasto de bolsillo promedio (SD) anual (en dólares) en pacientes con AR ascendió a $610.0 ($302.2), en EA a $578.6 ($220.5) y en gota a $245.3 ($124.0), lo que equivalió a 15, 9.6 y 2.5% del ingreso familiar, respectivamente. El gasto de bolsillo representó 26.1% del costo total anual por paciente con AR, 25.3% con EA y 24.4% con gota. Los costos directos institucionales esperados por paciente/año con AR fueron de $1724.2, con EA de $1710.8 y con gota de $760.7. El costo total anual por paciente con AR fue de $2334.3, con EA de $2289.4 y con gota de $1006.1. Los componentes del gasto de bolsillo de mayor cuantía fueron los medicamentos, exámenes de laboratorio y gabinete y las terapias alternativas. Conclusiones: Se concluye que desde la perspectiva del paciente, el costo de la AR, EA y gota equivale a la cuarta parte del costo médico directo. La AR es la enfermedad que mayor gasto implica.

Use of antibiotics in upper respiratory infections on patients under 16 years old in private ambulatory medicine.

OBJECTIVE: To assess antibiotic use for upper respiratory infections (URI) treatment on patients under 16 years-old who are beneficiaries of a pre-paid health care scheme. MATERIAL AND METHODS: A database containing the record of all the medical prescriptions for URI treatment, from May 1997 to April 1998 was analyzed. Patients were under 16 years old and had been diagnosed with common colds, pharyngitis, bronchitis, sinusitis, otitis, and other unspecified upper respiratory tract infections. Three hundred and fifty-one physicians of seven different specialties who attended 25,300 beneficiaries wrote such prescriptions. RESULTS: A total of 30,889 assorted medications were prescribed to 5,533 patients with the above diagnoses. Antibiotics were prescribed for 77.5% of all diagnoses, ranging from 58% for pharyngitis to 91% for laryngitis. The most frequently used antibiotics were: penicillin, cephalosporins, and macrolides. CONCLUSIONS: This study presents the information of antibiotics prescription practices for URI in a pre-paid health plan in Mexico. These findings may be used to support specific campaigns for rational use of antibiotics among children attended at private ambulatory health care practices.

Breast-feeding practices in Mexico: results from the Second National Nutrition Survey 1999.

OBJECTIVE: To assess breast-feeding (BF) practices and determinants of exclusive BF (EBF) < 4 and < 6 months (mo) among women and infants < 23 mo in the NNS-1999. MATERIAL AND METHODS: BF practices from the day and night before the interview were ascertained, and median duration estimated. Determinants of EBF < 4 and < 6 mo were analysed by logistic regression models for complex surveys. RESULTS: Prevalence of EBF < 4 mo was 25.7%, and of < 6 mo 20.3%. The overall rate of continued BF (second year) was 30.9%, median duration of BF 9 mo, and the national proportion of children ever breast-fed 92.3%. The probability (p) of EBF < 4 mo was determined by infant age and sex, by maternal socio-economic level (SEL) and ethnicity, and by the interaction between infant sex and SEL. The pEBF < 6 mo was determined by infant age and length, by maternal ethnicity, and employment. CONCLUSIONS: EBF rates and duration are low in Mexico and have improved only slightly in the last 20 y. Infant and maternal characteristics determine the pEBF. If improvements in infant health are a national priority, aggressive interventions to promote and protect BF are urgently needed in Mexico, as well as formal evaluation of current initiatives.

[Diagnosis and treatment of gout in Mexico City. Results from a physicians survey]. / El diagnóstico y tratamiento de la gota en la ciudad de México. Resultados de una encuesta a médicos.

UNLABELLED: The diagnosis and proper treatment for gout were described decades ago but these guides are not always realized in all the patients. OBJECTIVES: To evaluate by a mail survey sent to general physicians (GP), internal medicine physicians (IM), orthopedists (OP) and rheumatologists (RP) from Mexico city, the way they diagnose and treat gouty patients. SUBJECTS AND METHODS: The survey was anonymous and included 20 questions, it was sent by mail to 1,836 physicians (640 GP, 640 OP, 423 IM and 133 RP) living in Mexico city. RESULTS: The response was 6.8% OP, 10.4% IM, 10.8% GP and 41.4% RP. Eighty two to 95% of them attend gouty patients. Diclofenac was the drug most frequently used as the treatment for acute attacks, although a high frequency of glucocorticoids and allopurinol prescription for acute gout attacks was detected (28% OP and 49% GP respectively). Allopurinol is the drug more frequently used for the chronic treatment, it is also used for asymptomatic hyperuricemia by 43-84% of the physicians. Twenty five percent do not adjust initial allopurinol doses to glomerular filtration rate. The prophylactic treatment is used in only some cases and the dietetic restrictions were variable. Some points regarding the treatment of these patients are not according those recommended in the literature. CONCLUSIONS: We need to increase the knowledge between physicians about gout diagnosis and proper treatment. The adequate treatment is in most of the cases safe, cheap and effective.
