ABSTRACT

Objetivo: Discutir o papel das trombofilias na perda gestacional de repetição, com foco em prevalência/associação dessas patologias com perdas de repetição e seu tratamento, por meio de resultados de ensaios clínicos, revisões sistemáticas e metanálises. Métodos: Trata-se de uma revisão não sistemática de artigos publi- cados nas bases eletrônicas PubMed, Cochrane e SciELO nos últimos cinco anos, utilizando os seguintes descritores: "recurrent pregnancy loss", "recurrent abortion", "habitual abortion", "thrombophilia", "antiphospholipid syndrome" e "treatment". Resultados: A maioria dos estudos relatou forte associação entre os anticorpos antifosfolípides específicos e a síndrome do anticorpo antifosfolípide com perda gestacional de repetição. Mulheres portadoras da mutação do fator V de Leiden, mutação do gene da protrombina e deficiência de proteína S apresentaram alto risco de perda gestacional de repetição em uma grande revisão sistemática. Estudos recentes demonstraram taxas de prevalência das trombofilias hereditárias e da síndrome do anticorpo antifosfolípide, em mulheres com perda gestacional de repetição, semelhantes às da população em geral. Os estudos atuais endossam o uso da heparina associada à aspirina em mulheres com síndrome do anticorpo antifosfolípide, com aumento da taxa de nascidos vivos, mas sem diferença em re- lação às complicações obstétricas. Conclusão: Apesar de novos estudos demons- trarem que a prevalência das trombofilias hereditárias e adquiridas em mulheres com perda gestacional de repetição é semelhante à da população em geral, reco- menda-se a pesquisa rotineira de síndrome do anticorpo antifosfolípide nessas pacientes. O uso de aspirina em baixas doses associada à heparina é a intervenção farmacológica de primeira linha para a prevenção de perda gestacional de repeti- ção em pacientes com síndrome do anticorpo antifosfolípide.


Objective: To discuss the role of thrombophilias in recurrent pregnancy loss, focu- sing on the prevalence/association of these pathologies with recurrent abortion and treatment, through results of clinical trials, systematic reviews and meta-analyses. Methods: This is a non-systematic review of articles published in electronic databa- ses PubMed, Cochrane, SciELO in the last five years, using the following descriptors: "recurrent pregnancy loss", "recurrent abortion", "habitual abortion", "thrombophilia", "antiphospholipid syndrome", and "treatment". Results: Most studies have reported a strong association between specific antiphospholipid antibodies and antiphospho- lipid antibody syndrome with recurrent pregnancy loss. Women carrying the factor V Leiden mutation, prothrombin gene mutation, and protein S deficiency were shown to be at high risk of recurrent pregnancy loss in a large systematic review. Recent studies have shown prevalence rates of hereditary thrombophilias and antiphospholipid antibody syndrome, in women with re- current pregnancy loss, similar to those of the general po- pulation. Current studies endorse the use of heparin plus aspirin in women with antiphospholipid antibody syndrome, with an increase in live birth rate, but with no difference in obstetric complications. Conclusion: Although new studies demonstrate that the prevalence of hereditary and acquired thrombophilias in women with recurrent pregnancy loss is si- milar to that of the general population, routine investigation of antiphospholipid antibody syndrome in these patients is recommended. The use of low-dose aspirin plus heparin is the first-line pharmacological intervention for the prevention of recurrent pregnancy loss in patients with antiphospholipid antibody syndrome.

ABSTRACT

SUMMARY: This study investigated the role and mechanism of aspirin combined with rehabilitation training in the nerve injury repair and Schwann cell changes in rats with sciatic nerve injury. Totally, 120 male healthy SD rats were randomly divided into sham, model, aspirin, and aspirin + rehabilitation groups, with 30 rats in each group. The sciatic nerve function index (SFI), photothermal pain tolerance threshold and inclined plane test results at 4, 6, and 8 weeks after operation were compared. The distance of sensory nerve regeneration and the expression of S100B protein in Schwann cells were analyzed. Compared with the sham group, the SFI of the model, aspirin, and aspirin+rehabilitation groups were significantly lower at 4, 6, and 8 weeks after operation. However, the aspirin and aspirin+rehabilitation groups had significantly higher SFI than the model group. The SFI at 6 and 8 weeks after operation was higher in the aspirin+rehabilitation group than that in the aspirin group (P<0.05). The photothermal pain tolerance threshold of the sham, aspirin, and aspirin+rehabilitation groups were significantly higher than those of the model group at 4, 6, and 8 weeks after operation (P<0.05). The inclination angles of the model, aspirin, and aspirin+rehabilitation groups were significantly lower than those of the sham group at 4, 6, and 8 weeks after operation, and the inclination angle of the aspirin+rehabilitation group was significantly higher than that of the model and aspirin groups (P<0.05). The sensory nerve regeneration distance in aspirin and aspirin+rehabilitation groups was higher than that in the sham and model groups (P<0.05). The expression of S100B protein in the aspirin and aspirin+rehabilitation groups was higher than that in the model group (P<0.05). Aspirin combined with rehabilitation training can promote the functional recovery of sciatic nerve injury, and the mechanism may be related to the increase of the expression of S100B protein in Schwann cells.


En este estudio se investigó el papel y el mecanismo que desempeña la aspirina combinada, con el entrenamiento de rehabilitación en la reparación de lesiones nerviosas y los cambios en los schwannocitos en ratas con lesiones en el nervio ciático. En total, 120 ratas SD macho sanas se dividieron aleatoriamente en cuatro grupos de 30 ratas en cada uno: simulación, modelo, aspirina y aspirina + rehabilitación. Se compararon el índice de función del nervio ciático (SFI), el umbral de tolerancia al dolor fototérmico y los resultados de la prueba del plano inclinado a las 4, 6 y 8 semanas después de la operación. Se analizó la distancia de regeneración del nervio sensorial y la expresión de la proteína S100B en los schwannocitos. En comparación con el grupo simulado, el SFI de los grupos modelo, aspirina y aspirina+rehabilitación fue significativamente menor a las 4, 6 y 8 semanas después de la operación. Sin embargo, los grupos de aspirina y aspirina + rehabilitación tuvieron un SFI significativamente más alto que el grupo modelo. El SFI a las 6 y 8 semanas después de la operación fue mayor en el grupo de aspirina + rehabilitación que en el grupo de aspirina (P<0,05). El umbral de tolerancia al dolor fototérmico de los grupos simulado, aspirina y aspirina+rehabilitación fue significativamente mayor que el del grupo modelo a las 4, 6 y 8 semanas después de la operación (P<0,05). Los ángulos de inclinación de los grupos modelo, aspirina y aspirina+rehabilitación fueron significativamente menores que los del grupo simulado a las 4, 6 y 8 semanas después de la operación, y el ángulo de inclinación del grupo aspirina+rehabilitación fue significativamente mayor que el de los grupos modelo y aspirina (P<0.05). La distancia de regeneración del nervio sensorial en los grupos de aspirina y aspirina+rehabilitación fue mayor que en los grupos simulado y modelo (P<0,05). La expresión de la proteína S100B en los grupos de aspirina y aspirina+rehabilitación fue mayor que en el grupo modelo (P<0,05). La aspirina combinada con el entrenamiento de rehabilitación puede promover la recuperación funcional de la lesión del nervio ciático, y el mecanismo puede estar relacionado con el aumento de la expresión de la proteína S100B en los schwannocitos.

ABSTRACT

La Aspirina es una droga ampliamente utilizada con un protagonismo indiscutido en el escenario de la prevención secundaria. Sin embargo, el rol de este medicamento en prevención primaria es aún motivo de discusión. Los primeros ensayos que evaluaron la Aspirina en prevención primaria sugerían reducciones en el infarto agudo al miocardio y el accidente cerebrovascular -aunque no en la mortalidad- con un riesgo no despreciable de hemorragia mayor. Esto llevó a diversas sociedades científicas a recomendar su prescripción sólo en aquellos individuos con alto riesgo de eventos cardiovasculares. Desde el año 2018 en adelante, surgen diversos ensayos aleatorizados que han cuestionado estas indicaciones, mostrando beneficios clínicos muy discretos o ausentes. El objetivo de esta revisión es realizar un análisis histórico de la evidencia sobre el rol de la Aspirina en prevención primaria y resumir las recomendaciones actuales en este escenario.


Aspirin is widely used with a clear role in secondary prevention of cardiovascular diseases. However, its benefit in primary prevention is still a matter of discussion. The first trials evaluating Aspirin for primary prevention suggested reductions in acute myocardial infarction and stroke (although not in mortality) but with a non-negligible risk of major bleeding. This led to aspirin being recommended by various scientific societies, albeit limited to individuals at high risk of cardiovascular events. Since 2018 various randomized trials in primary prevention showed minimal or no beneficial effects of aspirin thus questioning its indication for this purpose. The aim of this review is to make an historical analysis of the evidence for the role of Aspirin in primary prevention and suggest modified recommendations for these subjects.

ABSTRACT

This study explored the effects of Buyang Huanwu Decoction(BYHWD) on platelet activation and differential gene expression after acute myocardial infarction(AMI). SD rats were randomly divided into a sham-operated group, a model group, a positive drug(aspirin) group, and a BYHWD group. Pre-treatment was conducted for 14 days with a daily oral dose of 1.6 g·kg~(-1) BYHWD and 0.1 g·kg~(-1) aspirin. The AMI model was established using the high ligation of the left anterior descending coronary artery method. The detection indicators included myocardial infarct size, heart function, myocardial tissue pathology, peripheral blood flow perfusion, platelet aggregation rate, platelet membrane glycoprotein CD62p expression, platelet transcriptomics, and differential gene expression. The results showed that compared with the sham-operated group, the model group showed reduced ejection fraction and cardiac output, decreased peripheral blood flow, and increased platelet aggregation rate and CD62p expression, and activated platelets. At the same time, TXB_2 content increased and 6-keto-PGF1α content decreased in serum. Compared with the model group, BYHWD increased ejection fraction and cardiac output, improved blood circulation in the foot and tail regions and cardiomyocytes arrangement, reduced myocardial infarct size and inflammatory infiltration, down-regulated platelet aggregation rate and CD62p expression, reduced serum TXB_2 content, and increased 6-keto-PGF1α content. Platelet transcriptome sequencing results revealed that BYHWD regulated mTOR-autophagy pathway-related genes in platelets. The differential gene expression levels were detected using real-time quantitative PCR. BYHWD up-regulated mTOR, down-regulated autophagy-related FUNDC1 and PINK genes, and up-regulated p62 gene expression. The results demonstrated that BYHWD could regulate platelet activation, improve blood circulation, and protect ischemic myocardium in AMI rats, and its mechanism is related to the regulation of the mTOR-autophagy pathway in platelets.

ABSTRACT

BACKGROUND@#Many nutritional supplements and pharmacological agents have been reported to show preventive effects on colorectal adenoma and colorectal cancer (CRC). We performed a network meta-analysis to summarize such evidence and assess the efficacy and safety of these agents.@*METHODS@#We searched PubMed, Embase, and the Cochrane Library for studies published in English until October 31, 2021 that fit our inclusion criteria. We performed a systematic review and network meta-analysis to assess the comparative efficacy and safety of candidate agents (low-dose aspirin [Asp], high-dose Asp, cyclooxygenase-2 inhibitors [coxibs], calcium, vitamin D, folic acid, ursodeoxycholic acid [UDCA], estrogen, and progesterone, alone or in combination) for preventing colorectal adenoma and CRC. Cochrane risk-of-bias assessment tool was employed to evaluate the quality of each included study.@*RESULTS@#Thirty-two randomized controlled trials (278,694 participants) comparing 13 different interventions were included. Coxibs significantly reduced the risk of colorectal adenoma (risk ratio [RR]: 0.59, 95% confidence interval [CI]: 0.44-0.79, six trials involving 5486 participants), advanced adenoma (RR: 0.63, 95% CI: 0.43-0.92, four trials involving 4723 participants), and metachronous adenoma (RR: 0.58, 95% CI: 0.43-0.79, five trials involving 5258 participants) compared with placebo. Coxibs also significantly increased the risk of severe adverse events (RR: 1.29, 95% CI: 1.13-1.47, six trials involving 7109 participants). Other interventions, including Asp, folic acid, UDCA, vitamin D, and calcium, did not reduce the risk of colorectal adenoma in the general and high-risk populations compared with placebo.@*CONCLUSIONS@#Considering the balance between benefits and harms, regular use of coxibs for prevention of colorectal adenoma was not supported by the current evidence. Benefit of low-dose Asp for chemoprevention of colorectal adenoma still requires further evidence.@*REGISTRATION@#PROSPERO, No. CRD42022296376.

ABSTRACT

OBJECTIVE@#To compare the expected population impact of benefit and risk of aspirin treatment strategies for the primary prevention of cardiovascular diseases recommended by different guidelines in the Chinese Electronic Health Records Research in Yinzhou (CHERRY) study.@*METHODS@#A decision-analytic Markov model was used to simulate and compare different strategies of aspirin treatment, including: Strategy ①: Aspirin treatment for Chinese adults aged 40-69 years with a high 10-year cardiovascular risk, recommended by the 2020 Chinese Guideline on the Primary Prevention of Cardiovascular Diseases; Strategy ②: Aspirin treatment for Chinese adults aged 40-59 years with a high 10-year cardiovascular risk, recommended by the 2022 United States Preventive Services Task Force Recommendation Statement on Aspirin Use to Prevent Cardiovascular Disease; Strategy ③: Aspirin treatment for Chinese adults aged 40-69 years with a high 10-year cardiovascular risk and blood pressure well-controlled (< 150/90 mmHg), recommended by the 2019 Guideline on the Assessment and Management of Cardio-vascular Risk in China. The high 10-year cardiovascular risk was defined as the 10-year predicted risk over 10% based on the 2019 World Health Organization non-laboratory model. The Markov model simulated different strategies for ten years (cycles) with parameters mainly from the CHERRY study or published literature. Quality-adjusted life year (QALY) and the number needed to treat (NNT) for each ischemic event (including myocardial infarction and ischemic stroke) were calculated to assess the effectiveness of the different strategies. The number needed to harm (NNH) for each bleeding event (including hemorrhagic stroke and gastrointestinal bleeding) was calculated to assess the safety. The NNT for each net benefit (i.e., the difference of the number of ischemic events could be prevented and the number of bleeding events would be added) was also calculated. One-way sensitivity analysis on the uncertainty of the incidence rate of cardiovascular diseases and probabilistic sensitivity analysis on the uncertainty of hazard ratios of interventions were conducted.@*RESULTS@#A total of 212 153 Chinese adults, were included in this study. The number of people who were recommended for aspirin treatment Strategies ①-③ was 34 235, 2 813, and 25 111, respectively. The Strategy ③ could gain the most QALY of 403 [95% uncertainty interval (UI): 222-511] years. Compared with Strategy ①, Strategy ③ had similar efficiency but better safety, with the extra NNT of 4 (95%UI: 3-4) and NNH of 39 (95%UI: 19-132). The NNT per net benefit was 131 (95%UI: 102-239) for Strategy ①, 256 (95%UI: 181-737) for Strategy ②, and 132 (95%UI: 104-232) for Strategy ③, making Strategy ③ the most favorable option with a better QALY and safety, along with similar efficiency in terms of net benefit. The results were consistent in the sensitivity analyses.@*CONCLUSION@#The aspirin treatment strategies recommended by the updated guidelines on the primary prevention of cardiovascular diseases showed a net benefit for high-risk Chinese adults from developed areas. However, to balance effectiveness and safety, aspirin is suggested to be used for primary prevention of cardiovascular diseases with consideration for blood pressure control, resulting in better intervention efficiency.

ABSTRACT

BACKGROUND@#Limited data are available on the changes in the quality of care for ST elevation myocardial infarction (STEMI) during China's health system reform from 2009 to 2020. This study aimed to assess the changes in care processes and outcome for STEMI patients in Henan province of central China between 2011 and 2018.@*METHODS@#We compared the data from the Henan STEMI survey conducted in 2011-2012 ( n = 1548, a cross-sectional study) and the Henan STEMI registry in 2016-2018 ( n = 4748, a multicenter, prospective observational study). Changes in care processes and in-hospital mortality were determined. Process of care measures included reperfusion therapies, aspirin, P2Y12 antagonists, β-blockers, angiotensin-converting enzyme inhibitors or angiotensin receptor blockers, and statins. Therapy use was analyzed among patients who were considered ideal candidates for treatment.@*RESULTS@#STEMI patients in 2016-2018 were younger (median age: 63.1 vs . 63.8 years) with a lower proportion of women (24.4% [1156/4748] vs . 28.2% [437/1548]) than in 2011-2012. The composite use rate for guideline-recommended treatments increased significantly from 2011 to 2018 (60.9% [5424/8901] vs . 82.7% [22,439/27,129], P <0.001). The proportion of patients treated by reperfusion within 12 h increased from 44.1% (546/1237) to 78.4% (2698/3440) ( P <0.001) with a prolonged median onset-to-first medical contact time (from 144 min to 210 min, P <0.001). The use of antiplatelet agents, statins, and β-blockers increased significantly. The risk of in-hospital mortality significantly decreased over time (6.1% [95/1548] vs . 4.2% [198/4748], odds ratio [OR]: 0.67, 95% confidence interval [CI]: 0.50-0.88, P = 0.005) after adjustment.@*CONCLUSIONS@#Gradual implementation of the guideline-recommended treatments in STEMI patients from 2011 to 2018 has been associated with decreased in-hospital mortality. However, gaps persist between clinical practice and guideline recommendation. Public awareness, reperfusion strategies, and construction of chest pain centers need to be further underscored in central China.

ABSTRACT

Abstract Telomerase enzyme is necessary for the elongation of telomeres while telomerase being critical for aging and cancer. Metformin, ibuprofen, and acetylsalicylic acid used in this research are drugs that millions of people already use and that many are likely to use in future. In this study, the effects of these drugs on telomerase activity of Mus musculus swiss albino mice in liver tissue were investigated and the telomerase activity was measured with a PCR-ELISA based kit. In the study a possible connection between telomerase enzyme activity and activities of antioxidant enzymes was also investigated by determining the activity of superoxide dismutase (SOD) and catalase enzymes. The data obtained show that metformin slightly decreased telomerase enzyme activity in low dose application; however, this change was not statistically significant. In ibuprofen application, there was a significant inhibitory effect when high doses were used; whereas, there was a slight inhibitory effect at low doses. In acetylsalicylic acid application, a slight activator effect was detected; it was not statistically significant, though. Metformin was observed to increase catalase and SOD activities in general while low and high doses of acetyl salicylic acid showed different effects. In addition, ibuprofen caused a statistically significant increase in liver SOD values. It is important to note that this study demonstrated a significant inhibitory effect of ibuprofen on telomerase enzyme activity in animal models..

ABSTRACT

Abstract Objective Currently, uteroplacental vascular disorders are considered one of the main mechanisms of spontaneous preterm delivery (PTD). Low-dose aspirin is used to prevent pre-eclampsia, which has a similar mechanism; hence, the present study aimed to investigate the effect of low-dose aspirin on the prevention of PTD in women with a history of spontaneous PTD. Methods The present pilot randomized clinical trial was conducted on 54 pregnant women in the aspirin group (taking 80 mg daily until the 36th week and classic treatment) and 53 patients in the control group (only receiving classic treatment). Results Forty-three patients (40%) presented before 37 weeks due to symptoms of PTL. Preterm delivery (< 37 weeks) occurred in 28 patients (26%), and there was no significant difference between the aspirin and control groups (10 patients [19%] and 18 patients [34%], respectively; p = 0.069). The time of preterm delivery was early (< 34 weeks) in 6 patients (21%), and its cause was spontaneous labor in 23 patients (82%) which was not significantly different between the two groups (p > 0.05). Out of 40 patients with spontaneous labor, 25 patients (63%) had a PTD, which was significantly lower in the aspirin group than in the control group (9 patients [45%] versus 16 patients [80%], respectively; p = 0.022). Conclusion The findings of the present study demonstrated that despite the reduction in the incidence of PTD using low-dose aspirin, the reduction rate was not statistically significant. On the other hand, in patients with spontaneous labor prone to PTD, aspirin was effective in reducing the incidence of PTD.


Resumo Objetivo Atualmente, os distúrbios vasculares uteroplacentários são considerados um dos principais mecanismos de parto prematuro espontâneo (PTD). A aspirina em baixa dose é usada para prevenir a pré-eclâmpsia, que tem um mecanismo semelhante; portanto, o presente estudo teve como objetivo investigar o efeito da aspirina em baixa dosagem na prevenção de PTD em mulheres com história de PTD espontâneo. Métodos O presente ensaio clínico piloto randomizado foi realizado em 54 gestantes do grupo aspirina (tomando 80 mg diários até a 36ª semana e tratamento clássico) e 53 pacientes do grupo controle (somente tratamento clássico). Resultados Quarenta e três pacientes (40%) apresentaram-se antes de 37 semanas devido a sintomas de PTL. O parto prematuro (< 37 semanas) ocorreu em 28 pacientes (26%) e não houve diferença significativa entre os grupos aspirina e controle (10 pacientes [19%] e 18 pacientes [34%], respectivamente; p = 0,069). O tempo de parto prematuro foi precoce (< 34 semanas) em 6 pacientes (21%) e sua causa foi trabalho de parto espontâneo em 23 pacientes (82%) que não foi significativamente diferente entre os dois grupos (p > 0,05). Das 40 pacientes com trabalho de parto espontâneo, 25 pacientes (63%) tiveram PTD, que foi significativamente menor no grupo aspirina do que no grupo controle (9 pacientes [45%] versus 16 pacientes [80%], respectivamente; p = 0,022). Conclusão Os achados do presente estudo demonstraram que, apesar da redução na incidência de DPT com o uso de aspirina em baixa dosagem, a taxa de redução não foi estatisticamente significativa. Por outro lado, em pacientes com trabalho de parto espontâneo propensas a PTD, a aspirina foi eficaz na redução da incidência de PTD.

ABSTRACT

Abstract Objective Aspirin (acetylsalicylic acid, ASA) and rivaroxaban are anticoagulants that have increased in popularity due to ease of use in the prevention of venous thromboembolism (VTE) after total knee arthroplasty (TKA). The present study aimed to evaluate the efficacy of ASA compared with that of rivaroxaban on VTE prophylaxis in patients who underwent TKA. Method Forty patients who had primary knee osteoarthritis and would undergo TKA were randomized into two groups. In total, 20 patients in the ASA group used oral aspirin, at a dose of 300 mg/day, for VTE prophylaxis after TKA, while 20 patients in the rivaroxaban group received oral rivaroxaban, at a dose of 10 mg/day. On days 4 and 14 after the operation, deep vein thrombosis (DVT) in the lower limbs on the operated side was detected through duplex ultrasonography. Other complications were recorded for 14 days. Results There were no positive findings of DVT detected with duplex ultrasonography in the groups of patients, and the occurrence of pulmonary embolism was not observed. In total, 4 patients had subcutaneous ecchymosis on the fourth postoperative day (2 patients in the ASA group and 2 patients in the rivaroxaban group; p= 1.0), and another 4 patients on the fourteenth postoperative day (1 patient in the ASA group and 3 patients in the rivaroxaban group; p= 0.292). No cases of wound hematoma, major organ bleeding, wound infection, or reoperation were observed in the sample. Conclusion Aspirin and rivaroxaban had comparable efficacy to prevent VTE, without increasing the incidence of wound complications and bleeding after TKA.


Resumo Objetivo A aspirina (ácido acetilsalicílico, AAS) e a rivaroxabana são anticoagulantes que vêm ganhando popularidade devido à facilidade de uso na prevenção do tromboembolismo venoso (TEV) após artroplastia total do joelho (ATJ). Este estudo teve como objetivo avaliar a eficácia do AAS em comparação com a da rivaroxabana na profilaxia de TEV em pacientes submetidos a ATJ. Método Quarenta pacientes com osteoartrite primária do joelho, que seriam submetidos a ATJ, foram randomizados em dois grupos. No total, 20 pacientes do grupo AAS usaram aspirina oral, na dose de 300 mg/dia, para a profilaxia do TEV após ATJ; e 20 pacientes do grupo rivaroxabana receberam uma dose oral de 10 mg/dia. No 4° e 14° dias do pós-operatório, trombose venosa profunda (TVP) dos membros inferiores no lado da cirurgia foi detectada por meio de ultrassonografia duplex. Foram registradas outras complicações durante catorze dias. Resultados Não foram detectados achados positivos de TVP com a ultrassonografia duplex nos grupos de pacientes, e não se observou a ocorrência de embolia pulmonar. No total, 4 pacientes apresentaram equimose subcutânea no 4° dia do pós-operatório (2 pacientes no grupo AAS e 2 pacientes no grupo rivaroxabana; p= 1,0), e outros 4 pacientes, no 14° dia do pós-operatório (1 paciente no grupo AAS e 3 pacientes no grupo rivaroxabana; p= 0,292). Nenhum paciente da amostra apresentou hematoma da ferida cirúrgica, sangramento de órgão importante, infecção da ferida, ou necessidade de nova cirurgia. Conclusão A aspirina e a rivaroxabana apresentaram eficácia comparável na prevenção do TEV, sem aumentar a incidência de complicações da ferida e sangramento após ATJ.

ABSTRACT

Under LPS-stimulus, platelets can activate macrophagesby a cell-to-cell contact or through cytokine degranulation. Rebound effects of anti-thrombotic agents, such as prostanoids and COX inhibitors can lead to thrombosis, infarct, and stroke. Aspirin has been prescribed for decades due to its powerful antiplatelet action, but it is also related to paradoxical effects such as withdrawal syndrome peaks, resistance, and thrombogenesis. Ultra-diluted aspirin can also produce the same effect in one hour, regardless of Cox-2, by still unknown pathways. Antithrombotic effects of aspirin are also reversed by its high dilutions.Aims: This study aims to characterize the effects of aspirin 15cH on macrophages challenged with LPS, a Cox-2 activator.Methodology: RAW 264.7 macrophages were sown in 24 wells plates using R10medium, boosted with 1µg/ml LPS,and treated with aspirin 15 cH and controls. The activity was evaluated after 24 hours. Supernatants were evaluated for cytokines, nitric oxide, and dielectric oscillations, through solvatochromic dyes (Cartwright's method).Results and discussion: macrophage spreading was increased by aspirin 15 cH, anLPS-like effect. Paradoxically, a significant reduction of this effect was noted when both, LPS and aspirin 15 cH, were added. Succussed water reversed the effect of LPS, leading to TNF (p<0.05) production close to baseline levels. Also, the single treatment with succussed water inhibited IL-10 production (p<0.05), but aspirin 200 µg/mL (positive control) highly increased it (p<0.0001), showing the validity of the model. Nitric oxide production was strengthened by LPS presence (p<0.0001), as expected, but partially downregulated after treatment with aspirin 200 µg/mL, water and succussed water. A pilot study with solvatochromic dyes showed no significant difference among treatments.Conclusion: The main data suggest that aspirin 15 cH increases macrophage activity but presents a paradoxal effect when mixed with LPS. On the other hand, succussed water itself has modulatory effects on macrophages.

ABSTRACT

Introdução: A Doença Periodontal tem caráter multifatorial, já que depende de condições microbiológicas, imunogenéticas e sistêmicas do hospedeiro. Representa inflamação crônica das estruturas de suporte e proteção dental. Desencadeia uma complexa estimulação imunológica, bem como a produção de citocinas inflamatórias, que mediam a destruição óssea e de tecido conjuntivo, provocando perda dental e complicações à distância. A compreensão da etiopatogênese, permitiu os conceitos de modulação, que referem-se às modificações dos aspectos danosos da resposta inflamatória. Objetivo: O presente artigo tem como objetivo realizar uma revisão dos estudos sobre as principais terapêuticas adjuvantes na modulação da resposta imune frente à doença periodontal. Revisão de Literatura: Foi realizada uma revisão da literatura, onde foram selecionados artigos científicos em inglês, publicados entre os anos 2005 a 2020, por meio das bases de dados PubMed e ScienceDirect. No decorrer das buscas, foram utilizadas as palavraschaves "Inflamation", "Periodontal Disease", "Subantimicrobial Dose of Doxycycline", "Periodontal Disease", "Host Response Modulation". Resultados e Conclusão: A literatura é bem promissora em relação à terapia de controle complementar da doença periodontal. Dessa forma, novas pesquisas nessa área podem trazer inúmeros beneficos aos pacientes, sendo, assim, um novo caminho para o contorno da resistência bacteriana(AU)


Introduction: Periodontal disease has a multifactorial character, depending on the host's microbiological, immunogenetic and systemic conditions. It represents chronic inflammation of dental support and protection structures. It triggers a complex immune stimulation, as well as the production of inflammatory cytokines, which mediate bone and connective tissue destruction, causing tooth loss and complications at a distance. The understanding of etiopathogenesis allowed the concepts of modulation, which refers to the modifications of the harmful aspects of the inflammatory response. This article has the escape of conducting a review of studies on the main mechanisms of modulation against periodontal disease. Objective: This article aims to rev iew the studies on the main modulation mechanisms in the face of periodontal disease. Literature Review: A literature review was carried out in which scientific articles were selected in English, published between 2005 and 2020, through the PubMed and ScienceDirect databases. During the searches, the keywords "Inflammation", "Periodontal Disease", "Subantimicrobial Dose of Doxycycline", "Periodontal Disease", "Host Response Modulation". Results and Conclusion: The literature is very promising with complementary control therapy for periodontal disease. Thus, new research in this area can bring countless benefits to patients, thus being a new way to bypass bacterial resistance(AU)

ABSTRACT

Abstract Objective To analyze whether acetylsalicylic (ASA) intake modifies the mean uterine arteries pulsatility index (UtA-PI) at the 2nd or 3rd trimester in a cohort of pregnant women with abnormal mean UtA-PI at between 11 and 14 weeks of gestation. Methods This is a retrospective cohort study. Singleton pregnancies with abnormal mean UtA-PI at between 11 and 14 weeks of gestation were studied. The participants were divided into 3 groups: 1) If the participant did not take ASA during pregnancy; 2) If the participant took ASA before 14 weeks of gestation; and 3) If the participant took ASA after 14 weeks of gestation. The mean UtA-PI was evaluated at the 2nd and 3rd trimesters, and it was considered to improve when it decreased below the 95th percentile. The prevalence ratio (PR) and the number needed to treat (NNT) werecalculated. Results A total of 72 participants with a mean UtA-PI>95th percentile at the 1st trimester of gestation were evaluated. Out of the 18 participants who took ASA, 8 participants started it before 14 weeks of gestation and 10 after. A total of 33.3% of these participants had improved the mean UtA-PI at the 2nd and 3rd trimesters of gestation, although it was not statistically significant (p=0.154). The prevalence ratio was 0.95 (95% confidence interval [CI]: 0.31-1.89), but between the 1st and 2nd trimesters of gestation, the PR was 0.92 (95%CI: 0.21-0.99) and it was statistically significant. Conclusion The present work demonstrates a modification of the mean UtA-PI in participants who took ASA compared with those who did not. It is important to check if ASA can modify the normal limits of uterine arteries because this could have an impact on surveillance.


Resumo Objetivo Analisar se a ingestão de acetilsalicílico (ASA) modifica o índice médio de pulsatilidade das artérias uterinas (UtA-PI) no 2° ou 3° trimestre em uma coorte de gestantes com média anormal de UtA-PI entre 11 e 14 semanas. Métodos Este é um estudo de coorte retrospectivo. Gravidezes únicas com média anormal de UtA-PI entre 11 e 14 semanas foram estudadas. As participantes foram divididas em 3 grupos: 1) Se a participante não tomou ASA durante a gravidez, 2) Se a participante tomou AAS antes das 14 semanas e 3) Se a participante tomou ASA após 14 semanas. A média do UtA-PI foi avaliada nos 2° e 3° trimestres e considerou-se que melhorava quando diminuía<95° percentil. Foram calculados a razão de prevalência (RP) e o número necessário para tratar (NNT). Resultados Foram avaliadas 72 participantes com média de UtA-PI>95° percentil no 1° trimestre de gravidez. Das 18 participantes que tomaram ASA, 8 participantes começaram antes de 14 semanas e 10 depois. Um total de 33,3% desses participantes melhoraram a média de UtA-PI nos 2° e 3° trimestres, embora não tenha sido estatisticamente significante (p=0,154). A razão de prevalência foi de 0,95 (intervalo de confiança [IC95%]: 0,31-1,89), mas entre os 1° e o 2° trimestres, a RP foi de 0,92 (IC95%: 0,21-0,99) e foi estatisticamente significativa. Conclusão O presente trabalho demonstra uma modificação da média de UtA-PI em participantes que faziam uso de ASA em comparação com aqueles que não faziam. É importante verificar se o ASA pode modificar os limites normais das artérias uterinas porque isso pode ter um impacto na vigilância.
