Background: Symptom management in rheumatoid arthritis (RA) remains a complex challenge. Widespread use of cannabis-based medicines for a myriad of symptoms has fostered rheumatology patients' interest. However, their safety and efficacy in RA remain unclear.Objective: The aim of this study was to perform a structured summary of the body of evidence in order to determine whether cannabis, cannabis-derived products, and synthetic cannabinoids are an effective treatment for rheumatoid arthritis.Methods: An electronic search in Epistemonikos database was performed to identify systematic reviews and their primary studies that addressed our clinical question. The body of evidence was collected in a pivot table in Epistemonikos. Information and data from the primary studies were extracted from the identified reviews. Finally, extracted data were reanalyzed, and a summary of findings table was generated using the Grading of Recommendations Assessment, Development and Evaluation approach.Results: Twenty-six systematic reviews were identified which included in total only 1 randomized trial assessing our clinical question.Conclusions: Cannabis, cannabis-derived products and synthetic cannabinoids may slightly reduce disease activity in patients with RA. Its use may result in little to no difference in pain reduction and may slightly increase nervous system adverse events. The evidence is very uncertain about the effect of cannabis, cannabis-derived products, and synthetic cannabinoids on serious adverse events risk.
OBJECTIVE: To assess the therapeutic effects of cannabis, cannabis-derived products and synthetic cannabinoids for rheumatoid arthritis. DESIGN: This is the protocol of a systematic review. DATA SOURCES: Searches will be conducted in PubMed/Medline, Embase, Cochrane Central Register of Controlled Trials (CENTRAL), trial registries, grey literature and in a centralized repository in L-OVE (Living OVerview of Evidence). L-OVE is a platform that maps PICO questions to evidence from Epistemonikos database. ELIGIBILITY CRITERIA FOR SELECTING STUDIES AND METHODS: We will include randomized controlled trials evaluating therapeutic use of cannabis, cannabis-derived products and synthetic cannabinoids for rheumatoid arthritis. Our primary interest will be in trials comparing the intervention with placebo or no treatment (intervention plus optimal treatment vs placebo plus optimal treatment or optimal treatment alone) in patients receiving optimal treatment for rheumatoid arthritis. Optimal treatment will be defined as disease modifying anti-rheumatic drugs. Two reviewers will independently screen each study for eligibility, extract data, and assess the risk of bias. We will perform random-effects meta-analyses and use Grading of Recommendations Assessment, Development and Evaluation (GRADE) to assess the certainty of the evidence for each outcome. ETHICS AND DISSEMINATION: The Scientific Ethics Committee of the Pontificia Universidad Católica de Chile granted ethical exemption for the realization of this study. Results of this review will be widely disseminated via peer-reviewed publications, social networks and traditional media and will be sent to relevant international organizations discussing this topic.
Summary Background Obesity increases the severity of coronavirus disease 2019 illness in adults. The role of obesity in short‐term complications and post‐acute sequelae in children is not well defined. Objective To evaluate the relationship between obesity and short‐term complications and post‐acute sequelae of SARS‐CoV‐2 infection in hospitalized paediatric patients. Methods An observational study was conducted in three tertiary hospitals, including paediatric hospitalized patients with a confirmatory SARS‐CoV‐2 RT‐PCR from March 2020 to December 2021. Obesity was defined according to WHO 2006 (0–2 years) and CDC 2000 (2–20 years) growth references. Short‐term outcomes were intensive care unit admission, ventilatory support, superinfections, acute kidney injury, and mortality. Neurological, respiratory, and cardiological symptoms and/or delayed or long‐term complications beyond 4 weeks from the onset of symptoms were considered as post‐acute sequalae. Adjusted linear, logistic regression and generalized estimating equations models were performed. Results A total of 216 individuals were included, and 67 (31.02%) of them had obesity. Obesity was associated with intensive care unit admission (aOR = 5.63, CI95% 2.90–10.94), oxygen requirement (aOR = 2.77, CI95% 1.36–5.63), non‐invasive ventilatory support (aOR = 6.81, CI95% 2.11–22.04), overall superinfections (aOR = 3.02 CI95% 1.45–6.31), and suspected bacterial pneumonia (aOR = 3.00 CI95% 1.44–6.23). For post‐acute sequalae, obesity was associated with dyspnea (aOR = 9.91 CI95% 1.92–51.10) and muscle weakness (aOR = 20.04 CI95% 2.50–160.65). Conclusions In paediatric hospitalized patients with COVID‐19, severe short‐term outcomes and post‐acute sequelae are associated with obesity. Recognizing obesity as a key comorbidity is essential to develop targeted strategies for prevention of COVID‐19 complications in children.
Letters to the Editor age. The potential triggers for TE are an acute illness with fever, systemic diseases, severe emotional stress, major surgery, rapid weight loss, nutritional deficiency, endocrine disorders and drug exposure. Acute TE occurs within 2-3 months after the triggering event and usually resolves itself on its own or if the trigger is eliminated. 2 Hair loss due to TE has been reported in adult patients following COVID-19 infection, 3 and only 1 pediatric patient with MIS-C. 4 This case highlights that hair loss may occur as a late complication of MIS-C. Future studies are needed to define the long-term complications of MIS-C.
Anti-Thymocyte Globulin (ATG) has become standard in preventing GvHD in related and unrelated donor transplantation. There needs to be a consensus on the best administration schedule. The PARACHUTE trial reported excellent CD4 immune reconstitution (CD4 IR) using a dosing schedule based on the patient's weight and pre-conditioning absolute lymphocyte count (ALC). In 2015 we introduced the PARACHUTE dosing schedule at our center. Patients received ATG doses according to weight and ALC starting day -9. One hundred one patients were transplanted for malignant and non-malignant diseases. CD4 IR+ was seen in 81% of patients. The incidence of grade II-IV and III to IV aGvHD was 26.6% and 15.3% and 5% for cGvHD with no severe cases. We found no difference in aGvHD between donor type and stem cell sources. Five-year EFS and OS were 77.5% and 83.5%. Grade III-IV GFRS was 75.2%. CD4 IR + patients had better EFS (93.1% vs. 77.7%, p=0.04) and lower non-relapse mortality (2.7% vs. 22.2%, p=0.002). The PARACHUTE ATG dosing schedule individualized by weight and ALC results in good early immune reconstitution, low incidence of cGvHD, and favorable survival for patients with different disease groups, donor types, and stem cell sources.
Resumen Objetivo Dar a conocer nuestra experiencia en el diagnóstico diferencial de los quistes óseos simple y aneurismático mediante estudio radiológico simple. Materiales y métodos Se incluyeron pacientes menores de 20 años con radiografía de quiste óseo simple o aneurismático histológicamente confirmado pertenecientes al Registro Nacional de Tumores Óseos. Las radiografías fueron analizadas por dos radiólogos experimentados. Se compararon las variables demográficas de los pacientes, y las variables clínicas y radiológicas de ambos quistes. Resultados Un total de 97 pacientes cumplieron los criterios de inclusión (65% presentaba quistes óseos simples y 35%, aneurismáticos). No se observaron diferencias en cuanto a la edad, al hueso comprometido, al tamaño de la lesión, a la expansión ósea, ni al adelgazamiento cortical. El género, la forma de presentación, la presencia de interrupción de la cortical, y la localización de la lesión en los ejes longitudinal y transversal del hueso son parámetros que podrían ser útiles en el diagnóstico diferencial de ambos quistes. Discusión Los quistes óseos simple y aneurismático son lesiones benignas frecuentes que, de acuerdo con la literatura, serían difíciles de diferenciar únicamente con radiografía simple. La resonancia magnética permite una mejor caracterización anatómica, y aporta sensibilidad y especificidad al diagnóstico. Sin embargo, debe ser precedida por la radiografía simple, y su disponibilidad es limitada. Conclusión Aun en centros con disponibilidad de resonancia magnética, la radiografía simple sigue siendo el estudio inicial de elección en el diagnóstico de tumores óseos. Ciertas características demográficas y radiográficas permiten orientar el diagnóstico diferencial inicial entre el quiste óseo simple y el aneurismático.
ResumenLa localización del osteocondroma en la tibia distal es poco frecuente y su crecimiento con compromiso y deformidad del peroné distal es aún más raro, haciéndolo una condición más sintomática que en otras ubicaciones. Factores como la severidad de los síntomas, deformidad progresiva del tobillo, complicaciones sindesmóticas, riesgo de fractura patológica o transformación maligna, junto con nuevas y mejores técnicas quirúrgicas, han llevado a que el manejo expectante de esas lesiones sea excepcional y escasamente reportado. Presentamos el caso de un joven de 17 años con osteocondroma solitario interóseo tibio distal sintomático y compromiso fibular, que fue exitosamente manejado en forma expectante. A los 5 años de seguimiento clínico-radiológico no presenta complicaciones y la lesión se mantiene estable.
Introducción: La rotura prematura ovular (RPO) antes de la viabilidad fetal consiste en una complicación obstétrica de baja incidencia, pero de alta morbimortalidad perinatal asociada. Estudios sugieren que el volumen de líquido amniótico (LA) es un factor importante a considerar. El objetivo de este trabajo es evaluar si en RPO ≤24 semanas, un bolsillo vertical máximo (BVM) <2cm al diagnóstico es un factor de riesgo para aparición de morbimortalidad fetal y neonatal.Métodos: Estudio de cohorte longitudinal retrospectivo de 94 pacientes con RPO ≤24 semanas ingresadas a un hospital terciario para manejo expectante entre los años 2005 y 2014. Embarazo gemelar o malformaciones congénitas fueron criterios de exclusión. Se obtuvieron y compararon 2 grupos según BVM al ingreso (BVM ≥ 2 cm y BVM < a 2 cms) y se comparó la edad gestacional (EG) al momento de la RPO y al parto, la latencia desde la RPO al parto, la presencia de corioamnionitis clínica, el número de óbitos fetales, muerte neonatal precoz (primeros 7 días de vida), tardía (entre los 7 y 28 días) y sobrevida global. Resultados: El 58% de las pacientes presentó un BVM <2 cm al ingreso, el cual se asoció a menor latencia al parto (p:0,01), menor EG al parto (p:0,02), más óbito fetal (p:0,04), mayor muerte neonatal precoz y tardía (p:0,02 y 0,01 respectivamente) además de menor sobrevida global (p:0,01).Conclusiones: La medición de BVM <2 cm al ingreso en pacientes con RPO ≤24 semanas, es un factor de mal pronóstico y debe ser considerado en el manejo clínico de estas pacientes.
