Pelvic Ewing Sarcoma: The Great Mimicker / Sarcoma de Ewing pélvico: o grande imitador

Abstract Ewing sarcoma is the most common malignant bone tumor of the pelvis in children and young adults. Even with aggressive treatment, its survival rate is amongst the poorest. Classical presentation may not be the rule. It may simulate clinically, imagiologically and histopathologically other nonmalignant entities. Therefore, its suspicion should not be overlooked. We report two cases of pelvic Ewing sarcoma: the first mimicking eosinophilic granuloma, and the second mimicking osteomyelitis. In the latter, we also report an atypical finding of its natural history: an initial response to antibiotic and anti-inflammatory treatment. In both cases, we highlight the possibility of an inconclusive percutaneous bone biopsy and the importance of immunochemistry and cytogenetics for the definitive diagnosis.

Resumo O sarcoma de Ewing é o tumor ósseo maligno da pelve mais comum em crianças e adultos jovens. Mesmo com tratamento agressivo, sua taxa de sobrevivência está entre as piores. A apresentação clássica pode não ser a regra. Ele pode simular clinicamente, imaginologicamente e histopatologicamente outras entidades não malignas. Portanto, sua suspeita não deve ser negligenciada. Relatamos dois casos de sarcoma pélvico: o primeiro imitando granuloma eosinofílico e o segundo imitando osteomielite. Neste último, também relatamos um achado atípico de sua história natural: uma resposta inicial ao antibiótico e ao tratamento anti-inflamatório. Em ambos os casos, destacamos a possibilidade de uma biópsia óssea percutânea inconclusiva e a importância da imunoquímica e da citogenética para o diagnóstico definitivo.

Evaluation of cell adhesion molecules (LFA-1 and L-selectin) in ankylosing spondylitis patients after treatment with ?-D-mannuronic acid (M2000)

Background & objectives: To examine ?-D-mannuronic acid (M2000) effects on L-selectin shedding and leucocyte function-associated antigen-1 (LFA-1) expression as mechanisms of action of this drug in patients with ankylosing spondylitis (AS). Methods: To investigate the molecular consequences of ?-D-mannuronic acid on L-selectin shedding, flow cytometry method was used. Furthermore, the effect of it on LFA-1 gene expression was analyzed by using quantitative real time (qRT)-PCR technique. Results: The LFA-1 expression in patients with AS was higher than controls (P=0.046). The LFA-1 expression after 12 wk therapy with ?-D-mannuronic acid was meaningfully decreased (P=0.01). After 12 wk treatment with ?-D-mannuronic acid, the frequency of CD62L-expressing CD4+ T cells in patients with AS, was not considerably altered, compared to the patients before therapy (P=0.5). Furthermore, after 12 wk therapy with ?-D-mannuronic acid, L-selectin expression levels on CD4+ T-cells in patients with AS, were not remarkably changed, compared to the expression levels of these in patients before treatment (P=0.2). Interpretation & conclusions: The results of this study for the first time showed that ?-D-mannuronic acid can affect events of adhesion cascade in patients with AS. Moreover, ?-D-mannuronic acid presented as an acceptable benefit to AS patients and could aid in the process of disease management

Clinician's dilemma: Naproxen-induced liver injury

Naproxen is a widely used nonsteroidal anti-inflammatory drug (NSAID) in pediatric population, used for mild-to-moderate pains, arthritis, and other immune-mediated disorders. It rarely causes clinically apparent liver injury in the adult population taking high doses of the drug over a prolonged period and is reported even rarer in pediatric population. We present a case of drug-induced liver injury (DILI) in a 13-year-old girl taking naproxen in therapeutic doses for juvenile rheumatoid arthritis. There was a complete recovery of liver function following discontinuation of naproxen therapy.

A new horizon in the prescription pattern of drugs for osteoarthritis in a tertiary care hospital: A prospective observational study

Background: Osteoarthritis (OA) is a significant contributor to chronic pain, mainly affecting lower extremity joints like the knee and hip, and causing considerable impairment in elderly individuals. OA treatment focuses on easing discomfort and enhancing mobility. Despite their adverse unfavorable effects, non-steroidal anti-inflammatory medications (NSAIDs) are frequently used for symptom alleviation. However, there is still a need for secure and efficient alternative therapies that could provide OA patients with both symptomatic relief and disease-modifying benefits. Despite the indisputable fact that the disease has a substantial socioeconomic impact on patients, there is not much research available to reflect on the medicine prescription pattern in OA. Aim and Objectives: The objectives of this study were to assess the prescription pattern and their rationality in patients with OA in a tertiary care hospital. Materials and Methods: A cross-sectional, prospective, and observational study conducted in the orthopedics department for all newly diagnosed and old treated patients with OA. Around 350 patients were taken into the study and their prescriptions were scrutinized. Descriptive statistics were used to analyze the data and present it as percentages. Results: Over 61.7% of females were affected compared to 38.3% of males with OA. The knee joint (76.2%) followed by the hip joint (13.7%) were the most common joints involved. Aceclofenac and diclofenac were the most common NSAIDs used in the patients, whereas piroxicam was the least prescribed drug. Gastroprotective agents, calcium supplements, and SYSDOA were the commonest adjuvants used in the treatment of OA patients. Conclusions: Even though NSAIDs are favored, SYSDOA and non-pharmacological treatments such as lifestyle changes, and frequent mild exercise have changed the treatment plan for OA

Diagnosis of a Case of Hepatotoxicity Due to Drugs and Herbal Supplements in a Hospital in Pasto, Colombia

The liver is a crucial organ in metabolism, and some substances can induce toxic hepatitis with high morbidity and mortality. Chemical and drug-induced liver disease is a diagnostic and therapeutic challenge since it requires extension studies to rule out other entities. We present the case of a 51-year-old female patient without underlying comorbidities, admitted due to symptoms of two-day evolution consisting of progressive jaundice, diarrheal episodes without acholia, or any other additional manifestation. Her condition was caused by the intake of nimesulide, two tablets a day for two days, for pain secondary to a mandibular cyst diagnosed in previous days. During her admission to the emergency room, the patient described chronic consumption of Herbalife® products daily for four years. She presented with elevated transaminases, prolonged prothrombin time (PT), and direct hyperbilirubinemia. Infectious and immunological diseases were ruled out. We decided to start antibiotic and vitamin K coverage. Finally, and by exclusion, a liver biopsy suggested an inflammatory process compatible with drug-induced hepatitis. The woman evolved favorably when the medication and dietary supplement were discontinued. In conclusion, this case constitutes an initial point in advancing research into hepatotoxicity by shared mechanisms of various substances simultaneously, such as what happened to the patient with the parallel use of Herbalife® and nimesulide.

El hígado es un órgano crucial en el metabolismo y algunas sustancias pueden inducir hepatitis toxica con alta morbimortalidad. La enfermedad hepática inducida por sustancias químicas y medicamentos es un desafío tanto diagnostico como terapéutico, puesto que requiere la realización de estudios de extensión para descartar otras entidades. A continuación se presenta el caso de una paciente femenina de 51 años sin comorbilidades de base, ingresada por clínica de 2 días de evolución consistente en ictericia progresiva, episodios diarreicos sin acolia ni otra manifestación adicional. Aparentemente, su cuadro fue provocado por la administración de nimesulida, 2 tabletas al día por 2 días, contra el dolor secundario a un quiste mandibular diagnosticado en días anteriores. Durante su ingreso a urgencias la paciente describió consumo crónico, a diario desde hace 4 años, de productos de Herbalife®. Cursa con elevación de transaminasas, prolongación del tiempo de protrombina (TP) e hiperbilirrubinemia directa. Se descartan enfermedades infecciosas e inmunológicas. Se decidió iniciar el cubrimiento antibiótico y vitamina K. Finalmente y por exclusión, se realizó una biopsia hepática que sugirió un proceso inflamatorio compatible con hepatitis inducida por fármacos. La mujer evolucionó favorablemente al suspender la medicación y el suplemento dietético referido. En conclusión, el caso expuesto constituye un punto inicial en el avance hacia la investigación en hepatotoxicidad por mecanismos compartidos de diversas sustancias simultáneamente, como lo sucedido a la paciente con el uso paralelo de Herbalife® y de nimesulida.

Anti-inflammatory treatment after selective laser trabeculoplasty: a systematic review of the literature and meta-analysis of randomized control trials / Tratamento anti-inflamatório após trabeculoplastia seletiva a laser: revisão sistemática da literatura e meta-análise de ensaios clínicos randomizados controlados

ABSTRACT We assessed the effects of anti-inflammatory treatment after selective laser trabeculoplasty through a systematic search of the MEDLINE, COCHRANE, and ClinicalTrials.gov. The outcome measures were intraocular pressure, anterior chamber inflammation, and discomfort. Evidence synthesis was performed using fixed effects or random-effects model according to the heterogeneity of the included studies. Heterogeneity was assessed using Q-statistic and I2. For an overall estimate of continuous outcomes, the mean differences and their 95% confidence intervals were applied, while odds ratios and their 95% confidence intervals were applied for dichotomous outcomes. Six studies were included in all. No significant difference was noted in the patients for intraocular pressure and discomfort when treated with anti-inflammatory drops. However, the patients showed benefit from reduced anterior chamber inflammation in the first postoperative week [FE OR=0.43, 95% CI=(0.19, 0.95), PQ=0.97, I2=0%], with no significant difference between the outcomes of non-steroidal anti-inflammatory drugs and steroids [FE OR=0.75, 95% CI=(0.20, 2.82), PQ=0.37, I2=0%]. Anti-inflammatory drops reduce anterior chamber inflammation after selective laser trabeculoplasty but showed no effect on the intraocular pressure.

RESUMO O objetivo deste estudo é avaliar os efeitos do tratamento anti-inflamatório após a trabeculoplastia seletiva a laser. Uma busca sistemática foi feita no MEDLINE, COCHRANE e ClinicalTrials.gov. As medidas de resultado foram pressão intraocular, inflamação da câmara anterior e desconforto. A síntese de evidência foi realizada utilizando-se modelo de efeitos fixos ou efeitos aleatórios, de acordo com a heterogeneidade dos estudos incluídos. A heterogeneidade foi avaliada utilizando-se Q-statistic e I². Para uma estimativa global dos resultados contínuos, foram usadas diferenças médias e seus intervalos de confiança de 95% enquanto para resultados dicótomos, usou-se odds ratios e seus intervalos de confiança de 95%. Seis estudos foram incluídos. Nenhuma diferença significativa foi encontrada em pacientes tratados com gotas anti-inflamatórias em termos de pressão intraocular e desconforto. No entanto, eles se beneficiaram da redução da inflamação da câmara anterior na primeira semana pós-operatória [FE OR=0,43, IC 95% = (0,19, 0,95), PQ=0,97, I2=0%], sem diferença significativa entre anti-inflamatórios não esteroidais e esteroidais [FE OR=0,75, IC 95% = (0,20, 2,82), PQ=0,37, I2=0%]. Gotas anti-inflamatórias reduzem a inflamação da câmara anterior após trabeculoplastia seletiva a laser, não afetando a pressão intraocular.

Differences of resting-state percent amplitude of fluctuations among migraineurs without aura with different efficacy of non-steroidal anti-inflammatory drugs / 中华行为医学与脑科学杂志

Objective:To explore the differences of resting-state spontaneous neural activity between migraine without aura (MwoA) patients with response or nonresponse to non-steroidal anti-inflammatory drugs (NSAIDs), and its correlation with migraine-related features.Methods:From February 2021 to April 2022, thirty MwoA patients with response to NSAIDs, 30 MwoA patients with nonresponse to NSAIDs, and 30 healthy controls were recruited in the Affiliated Jiangning Hospital of Nanjing Medical University.All subjects were scanned with a 3.0 T resting-state functional magnetic resonance imaging scanner.The percent amplitude of fluctuation (perAF) approach was used to calculate the differences of the resting state brain functional activities among the three groups (Bonferroni multiple comparison correction). SPSS 24.0 software and RESTplus software were used for statistical analysis.Analysis of variance was used for the perAF values of three groups.Correlation analysis was performed between perAF values of brain regions with significant differences and migraine-related features.Results:The brain areas showing significant differences of perAF among the three groups located in the left anterior cingulate cortex (ACC)( x, y, z = -6, 9, -3), left middle frontal gyrus (MFG)( x, y, z =-39, 48, 9) and left middle temporal gyrus (MTG)( x, y, z = -57, -30, -15)(all P<0.05, Bonferroni correction). Compared with nonresponse group, the perAF in response group showed significant decreased in the left ACC, MFG and MTG.There was positive correlation between the perAF of left ACC and disease duration ( r=0.506, P=0.007). Compared with healthy controls, the perAF of nonresponse group showed increased in the left ACC, which was negatively correlated with frequency ( r=-0.414, P=0.032). Conclusion:The neural activity of prefrontal cortex and ACC may be the neuropathological basis underlying response to NSAIDs in MwoA treatment.Moreover, the ACC has certain correlations with migraine-related characteristics, which may serve as a potential neuroimaging biomarker to evaluate the efficacy of NSAIDs.

Efficacy，safety and cost-effectiveness of polyisobutylene-type Gutong plaster in the treatment of osteoarthritis in Chinese adults / 中国药房

OBJECTIVE To evaluate the efficacy， safety and cost-effectiveness of polyisobutylene （PIB）-type Gutong plaster （called “PIB Gutong plaster” for short） versus non-steroidal anti-inflammatory drugs （NSAIDs） in the treatment of osteoarthritis in Chinese adults. METHODS Based on a real-world study， after propensity score matching， the decrease in pain visual simulation score， utility increase， time to pain resolution， time to return to normal range of motion and total adverse events of PIB Gutong plaster versus three NSAIDs （celecoxib， diclofenac sodium， and ibuprofen） were evaluated. Cost-utility analysis was used to calculate the incremental cost-effectiveness ratio （ICER） of patients using PIB Gutong plaster versus the three NSAIDs from the perspective of the whole society， and sensitivity analysis was carried out. RESULTS In terms of effectiveness， the recovery time of joint activity in PIB Gutong plaster group was significantly longer than that in celecoxib group， the decrease in VAS score of PIB Gutong plaster was significantly higher than that of ibuprofen but significantly lower than that of diclofenac sodium； the time of pain disappearance was longer than that in diclofenac sodium group and ibuprofen group， and the increase in health utility was significantly lower than that in diclofenac sodium group （P＜0.05）. In terms of safety， there were no significant differences in the incidence and severity of adverse events of PIB Gutong plaster， compared with the three NSAIDs， without statistical significance （P＜0.05）. In terms of cost-effectiveness， compared with celecoxib and diclofenac sodium， PIB Gutong plaster was dominant. Compared with ibuprofen， the ICER value of PIB Gutong plaster was 178 611.58 yuan/QALY， indicating that at the current price， PIB Gutong plaster was cost-effective if the threshold was 3 times GDP per capita. The results of sensitivity analysis were consistent with those of basic analysis. CONCLUSIONS The efficacy of PIB Gutong plaster was better than that of ibuprofen， similar to that of celecoxib， but worse than that of diclofenac sodium， the safety was consistent with the three NSAIDs， and the cost-effectiveness of PIB Gutong plaster needs to be improved.

A novel mesenchymal stem cell-based regimen for acute myeloid leukemia differentiation therapy

Currently the main treatment of acute myeloid leukemia (AML) is chemotherapy combining hematopoietic stem cell transplantation. However, the unbearable side effect of chemotherapy and the high risk of life-threatening infections and disease relapse following hematopoietic stem cell transplantation restrict its application in clinical practice. Thus, there is an urgent need to develop alternative therapeutic tactics with significant efficacy and attenuated adverse effects. Here, we revealed that umbilical cord-derived mesenchymal stem cells (UC-MSC) efficiently induced AML cell differentiation by shuttling the neutrophil elastase (NE)-packaged extracellular vesicles (EVs) into AML cells. Interestingly, the generation and release of NE-packaged EVs could be dramatically increased by vitamin D receptor (VDR) activation in UC-MSC. Chemical activation of VDR by using its agonist 1α,25-dihydroxyvitamin D3 efficiently enhanced the pro-differentiation capacity of UC-MSC and then alleviated malignant burden in AML mouse model. Based on these discoveries, to evade the risk of hypercalcemia, we synthetized and identified sw-22, a novel non-steroidal VDR agonist, which exerted a synergistic pro-differentiation function with UC-MSC on mitigating the progress of AML. Collectively, our findings provided a non-gene editing MSC-based therapeutic regimen to overcome the differentiation blockade in AML.

Os anti-inflamatórios não esteroidais (AINE) são os fármacos mais frequentemente associados a reações de hipersensibilidade (RH) na prática clínica. Na parte 2 dessa atualização sobre as RH aos AINE, discutiremos os aspectos clínicos dessas reações, com foco nos sinais e sintomas, como diferenciar os fenótipos clínicos, fazer a orientação desses pacientes e quando indicar procedimentos complementares, como testes cutâneos, de provocação e dessensibilização.

Nonsteroidal anti-inflammatory drugs are a major cause of drug hypersensitivity reactions in clinical practice. In this "Update Part 2", we discuss the clinical picture, including the main signs and symptoms, how to distinguish clinical phenotypes, how to manage affected patients, and when to indicate additional procedures, such as skin testing, challenge, and desensitization.

Drug-induced Stevens-Johnson syndrome: A case series

Stevens-Johnson syndrome (SJS) can be defined as a rare, serious disorder of the skin and mucous membrane characterized by widespread vesiculobullous rash with epidermal sloughing and necrosis involving mainly eyes, oral cavity, and skin. SJS can be diagnosed if there is <10% of the skin involvement. SJS occurs as an idiosyncratic reaction to various medications. Among them, the most common are antimicrobial agents (AMAs), antiepileptics, and non-steroidal anti-inflammatory drugs (NSAIDs). SJS is one of the dermatological emergencies for which initial treatment can only be supportive like fluids and nasogastric or parenteral feeding and symptomatic measures like analgesic mouth rinse for mouth ulcer. Beyond this, no treatment for SJS is approved. Cases of drug-induced SJS as diagnosed by Skin and VD department were included in the study. Interpretations were drawn out from that data and causality assessment was done according to the WHO-UMC causality assessment. Total four cases of drug-induced SJS were available. two cases of male patients and two of female patients. Out of them, three cases were by NSAIDs induced and one case was anti-epileptic (phenytoin) induced. In the present study, it was found that three of the cases of drug-induced SJS were caused NSAIDs and one case by anti-epileptic. According to the WHO-UMC Causality assessment, three cases were probable and one was unclassified.

Efectos antirresortivos y antimicrobianos de los antiinflamatorios no esteroideos en lesiones periapicales / Antiresorptive and antimicrobial effects of nonsteroidal anti-inflammatory drugs in periapical lesion

Los antiinflamatorios no esteroideos (AINE) son un grupo de fármacos que han sido comúnmente prescritos por sus propiedades antiinflamato- rias, antipiréticas y analgésicas, mismas que se deben a la inhibición de la formación de prostaglandinas. Este mecanismo ha sido ampliamente respaldado en la literatura; sin embargo, en la actualidad poco se co- noce sobre las propiedades adicionales de estos medicamentos como el efecto antirresortivo y antimicrobiano. La función antirresortiva se debe principalmente al bloqueo de la producción de prostaglandinas en específico la PGE2, que posee gran potencial osteoclastogénico, esencial para la aparición de lesiones periapicales; asimismo, la acción antimicrobiana de los AINE está relacionada con la afectación directa de la perpetuación de biopelícula, potencian la acción de los antibióticos, entre otros. Dichos efectos combinados podrían contribuir en la cura- ción de lesiones periapicales. El objetivo de este estudio es recopilar información actualizada sobre estas funciones agregadas de los AINE, con el fin de dar a conocer a los profesionales estos beneficios en la terapéutica de las lesiones periapicales (AU)

Non-steroidal anti-inflammatory (NSAIDs) are a group of drugs that have been commonly prescribed for their anti-inflammatory, antipyretic and analgesic properties, which are due to the inhibition of prostaglandin formation. This mechanism has been widely supported in the literature; however, currently little is known about the additional properties of these drugs such as the antiresorptive and antimicrobial effect. The antiresorptive function is mainly due to the blockage of prostaglandin production, specifically PGE2, which has great osteoclastogenic potential, and is essential for the appearance of periapical lesions; likewise, the antimicrobial action of NSAIDs is related to the fact that they directly affect the perpetuation of biofilms, enhance the action of antibiotics, among others. These combined effects could contribute to the healing of periapical lesions. The aim of this study is to gather updated information on these added functions of NSAIDs, in order to inform professionals about these benefits in the therapy of periapical lesion (AU)

Abstract The aim of this study was to investigate the physicochemical and biological properties of an experimental tricalcium silicate-based repair cement containing diclofenac sodium (CERD). For the physicochemical test, MTA, Biodentine and CERD were mixed and cement disc were prepared to evaluate the setting time and radiopacity. Root-end cavity were performed in acrylic teeth and filled with cements to analyze the solubility up to 7 days. Polyethylene tubes containing cements were prepared and calcium ions and pH were measured at 3h, 24h, 72h and 15 days. For the biological test, SAOS-2 were cultivated, exposed to cements extracts and cell proliferation were investigated by MTT assay at 6h, 24h and 48h. Polyethylene tubes containing cements were implanted into Wistar rats. After 7 and 30 days, the tubes were removed and processed for histological analyses. Parametric and nonparametric data were performed. No difference was identified in relation to setting time, radiopacity and solubility. Biodentine released more calcium ion than MTA and CERD; however, no difference between MTA and CERD were detected. Alkaline pH was observed for all cements and Biodentine exhibited highest pH. All cements promoted a raise on cell proliferation at 24h and 48h, except CERD at 48h. Biodentine stimulated cell metabolism in relation to MTA and CERD while CERD was more cytotoxic than MTA at 48h. Besides, no difference on both inflammatory response and mineralization ability for all cement were found. CERD demonstrated similar proprieties to others endodontic cements available.

O pH alcalino foi observado para todos os cimentos e o Biodentine exibiu o pH mais alto. Todos os cimentos promoveram aumento na proliferação celular às 24h e 48h, exceto o CERD às 48h. Biodentine estimulou o metabolismo celular em relação ao MTA e CERD, enquanto CERD foi mais citotóxico do que MTA em 48h. Além disso, nenhuma diferença foi encontrada na resposta inflamatória e na capacidade de mineralização para todos os cimentos. CERD demonstrou propriedades semelhantes a outros cimentos endodônticos disponíveis.

Prescripción de protectores gástricos en pacientes reumatológicos: análisis desde Consulta Externa de Gastroenterología / Prescription of gastric protectors in rheumatological patients: Analysis from a gastroenterology outpatient clinic

Introducción: Los antinflamatorios no esteroideos son los medicamentos más recetados por reumatólogos y traumatólogos. Pero a pesar de tener una eficacia similar para controlar la inflamación y el dolor, los diferentes antinflamatorios no esteroideos disponibles presentan variabilidad en su perfil de seguridad. Objetivo: Brindar una panorámica sobre la prescripción de protectores gástricos en pacientes reumatológicos, en dos centros hospitalarios, desde una perspectiva gastroenterológica. Métodos: La investigación se inscribe en el paradigma cuantitativo con un estudio observacional. Se conformaron dos grupos de pacientes, uno de ellos provenientes del hospital A y el segundo grupo pertenecía al hospital B. Discusión: Los gastroprotectores se han convertido en los fármacos de mayor demanda en las farmacias comunitarias de Ecuador, y los más prescritos son los inhibidores de la bomba de protones y en menor frecuencia los antihistamínicos H2. Respecto a los gastroprotectores más frecuentemente prescritos, según nuestro estudio, estos valores podrían obedecer a la disponibilidad y los costos de la famotidina y el omeprazol con respecto a otros medicamentos de probada eficacia (ansoprazol, pantoprazol, rabeprazol y ranitidina). Conclusiones: Durante los últimos años, el uso de los fármacos gastroprotectores en América Latina ha experimentado un importante desarrollo, con la observancia de normas y guías clínicas de manejo de casos que ofrecen recomendaciones importantes al respecto. Por tanto, desde una perspectiva gastroenterológica, para tener éxito, es indispensable procurar un conocimiento de estos aportes y evidencias científicas(AU)

Introduction: Nonsteroidal anti-inflammatory drugs are the most prescribed medications by rheumatologists and traumatologists. However, despite having similar efficacy in controlling inflammation and pain, the different available nonsteroidal anti-inflammatory drugs show variability in their safety profile. Objective: To provide an overview of the prescription of gastric protectors in rheumatological patients, in two hospital centers, from a gastroenterological perspective. Methods: The research is part of the quantitative paradigm with an observational study. Two groups of patients were formed, one of them from hospital A and the second group belonged to hospital B. Discussion: Gastroprotectors have become the drugs in greatest demand in community pharmacies in Ecuador, the most prescribed being Proton Pump Inhibitors (IBPS) and, to a lesser extent, H2 antihistamines (anti-H2). Regarding the most frequently prescribed gastroprotectors, according to our study, these values ​​could be due to the availability and costs of famotidine and omeprazole compared to other drugs with proven effectiveness, such as ansoprazol, pantoprazole, rabeprazole and ranitidine. Conclusions: In recent years, the use of gastroprotective drugs in Latin America has undergone significant development, with the observance of clinical case management norms and guidelines that offer important recommendations in this regard. Therefore, from a gastroenterological perspective, to be successful, it is essential to seek knowledge of these contributions and scientific evidence(AU)

Efectos de los antiinflamatorios no esteroideos en las tendinopatías / Effects of Non-Steroidal Anti-Inflammatory Drugs in Tendinopathies

Introducción: Los antiinflamatorios no esteroideos son comúnmente usados para el tratamiento de las tendinopatías, pero la evidencia sobre este tratamiento es escasa. Objetivo: Realizar una revisión sistemática acerca de los efectos de los en las tendinopatías. Métodos: Se desarrolló una búsqueda bibliográfica en PubMed, WOS, PEDro, Medline, Cinahl y SPORTDiscus. Se incluyeron un total de 13 ensayos clínicos con una calidad metodológica media de 7,15/10 en la escala PEDro. Conclusiones: En la mayoría de los artículos se observó una mejoría corto plazo en el dolor y la funcionalidad con el uso de AINEs. Los ensayos clínicos incluidos no analizaron la presencia de inflamación en esta patología. Se necesitan más estudios que determinen la función de la inflamación en la tendinopatía que justifique el uso de los antiinflamatorios no esteroideos(AU)

Introduction: Non-steroidal anti-inflammatory drugs are commonly used for the treatment of tendinopathies, but the evidence on this treatment is scarce. Objective: To carry out a systematic review about the effects of non-steroidal anti-inflammatory drugs in tendinopathies. Methods: A bibliographic search was carried out in PubMed, WOS, PEDro, Medline, Cinahl and SPORTDiscus. A total of 13 clinical trials with a mean methodological quality of 7.15/10 on the PEDro scale were included. Conclusions: In most of the articles, a short-term improvement in pain and functionality was observed with the use of non-steroidal anti-inflammatory drugs. The clinical trials included did not analyze the presence of inflammation in this pathology. More studies are needed to determine the role of inflammation in tendinopathy that justifies the use of nonsteroidal anti-inflammatory drugs(AU)

Detección de factores de riesgo de enfermedad renal crónica en adultos / Detection of Risk Factors for Chronic Kidney Disease in Adults

Introducción: La enfermedad renal crónica se considera una enfermedad con graves repercusiones para la sociedad y las políticas de salud, con elevada incidencia y prevalencia debido al alza de enfermedades como la hipertensión arterial y la diabetes mellitus. Objetivo: Detectar, de forma oportuna, adultos con alto riesgo de desarrollar enfermedad renal crónica para preservar su salud, y así frenar la aparición y progresión del daño renal. Métodos: Se realizó un estudio descriptivo, transversal, cuantitativo, con 404 adultos familiares de estudiantes de enfermería, Universidad Técnica de Machala, El Oro, Ecuador. Se utilizó el Cuestionario de Detección Temprana de Riesgo de la Enfermedad Renal, del grupo Da Vita. Resultados: La hipertensión arterial fue la principal enfermedad hallada con (27,2 por ciento), seguido de la diabetes mellitus tipo II (9,4 por ciento). La prueba Chi-cuadrado no apuntó diferencia en el antecedente de hipertensión arterial entre ambos sexos (p > 0,05). De la población de estudio, 55,6 por ciento presentaba obesidad/sobrepeso, 54,7 por ciento refirió sedentarismo, 120 personas (29,7 por ciento) presentaron antecedentes familiares de ERC. Un total de 137 personas (33,9 por ciento) refirió que consumía antinflamatorios no esteroideos. El total de pacientes con hipertensión arterial y diabetes mellitus (n = 17, 4.21 por ciento), eran obesos, sedentarios, y todos presentaron antecedentes familiares de enfermedad renal crónica, por lo que se consideraron alto riesgo. Fueron enviados a consulta para estudio, además de recibir las charlas educativas. Conclusiones: El profesional de la salud puede y debe incidir en la detección temprana de la enfermedad renal crónica, mediante pesquisa y programas educativos que aumenten el conocimiento de la población susceptible(AU)

Introduction: Chronic kidney disease is considered a disease with serious repercussions for the society and health policies, with high incidence and prevalence due to the rise of diseases such as arterial hypertension and diabetes mellitus. Objective: To detect, in a timely manner, adults at high risk of developing chronic kidney disease in order to preserve their health, and thus slow the onset and progression of kidney damage. Methods: A descriptive, cross-sectional and quantitative study was carried out with 404 adult relatives of nursing students from the Technical University of Machala, El Oro, Ecuador. The questionnaire for early detection of renal disease risk of the Da Vita group was used. Results: Arterial hypertension was found as the main disease (27.2 percent), followed by type II diabetes mellitus (9.4 percent). The chi-square test showed no difference in the history of hypertension between both sexes (p > 0.05). Of the study population, 55.6 percent were obese/overweight, 54.7 percent reported a sedentary lifestyle, and 120 persons (29.7 percent) had a family history of chronic kidney disease. A total of 137 persons (33.9 percent) reported consuming nonsteroidal antiinflammatory drugs. The total of patients with arterial hypertension and diabetes mellitus (n = 17; 4.21 percent) were obese, sedentary, and had a family history of chronic kidney disease, a reason why they were considered at high risk. They were referred to consultation for study, in addition to receiving educational talks. Conclusions: The health professional can and should have an impact on the early detection of chronic kidney disease through screening and educational programs that increase the knowledge of the susceptible population(AU)
