ABSTRACT

Objetivo: Evaluar el valor predictivo negativo de la ratio antigénica y conocer su rentabilidad para descartar preeclampsia precoz en pacientes de alto riesgo de desarrollarla, con profilaxis de ácido acetilsalicílico. Métodos: Se realizó un estudio descriptivo transversal que recogió a las gestantes con cribado de preeclampsia precoz de alto riesgo (384 gestantes) en el Hospital Santa Lucía durante el año 2021, para lo que se usó test Elecsys® tabulado a un riesgo mayor a 1/150 en primer trimestre, y que tomaran ácido acetilsalicílico antes de la semana 16, quedando en 368 gestantes vistas en las semanas 20, 26, 31 y 36. Se realizó biometría, ratio angiogénica y doppler. Resultados: La incidencia de preeclampsia precoz en la población fue 4 casos (incidencia 1,08 %). Son significativos por su alto valor predictivo negativo del 100 % de preeclampsia precoz: la ratio angiogénica mayor a 38 en la semana 26 y el doppler de las uterinas en semana 20 y 26. Conclusión: En gestaciones con cribado de alto riesgo de preeclampsia que tomen ácido acetilsalicílico, una ratio angiogénica menor a 38 en la semana 26, además de un doppler uterino normal en semana 20 y 26 permite reducir el seguimiento gestacional(AU)


Objective: Our main objective was to evaluate the negative predictive value of the angiogenic ratio and to know its profitability to rule out early preeclampsia in patients at high risk of early preeclampsia with acetylsalicylic acid prophylaxis. Methods: A cross-sectional descriptive study was carried out that included pregnant women with high-risk early preeclampsia screening (384 pregnant women) at the Santa Lucía Hospital during the year 2021, for which the Elecsys® test tabulated at a risk >1/ was used. 150 in the first trimester, and who take acetylsalicylic acid before week 16, leaving 368 pregnant women seen in weeks 20, 26, 31 and 36, with biometry, angiogenic ratio and Doppler performed. Results: The incidence of early preeclampsia in the population was 4 cases (incidence 1.08%). They are significant due to their high negative predictive value of 100% of early preeclampsia: Angiogenic ratio > 38 in week 26, uterine Doppler in weeks 20 and 26. Conclusion: Pregnancies with high risk screening for preeclampsia who take acid acetylsalicylic acid, an angiogenic ratio < 38 at week 26 in addition to a normal uterine Doppler at weeks 20 and 26 allows for reduced gestational follow-up(AU)

ABSTRACT

Background: Approximately 5-10 % of pregnancies are complicated by pre- eclampsia and it is a prime cause for maternal and perinatal mortality and morbidity worldwide, particularly in developing countries. In pre-eclampsia insufficient invasion of maternal spiral arteries by the trophoblast early in gestation due to abnormal implantation or maternal vascular disease results in impaired placental perfusion. Aspirin is a potent anti-inflammatory drug, has been shown to inhibit the biosynthesis and release of prostaglandins, even in low dosage. Ingestion of low dose aspirin may result in a decrease in the incidence of pre-eclampsia and fetal growth restriction and the precise mechanism by which it prevents preeclampsia in some women is also uncertain.Methods: The present prospective observational study was carried out in females between 18-20 weeks of gestation with raised uterine artery PI attending antenatal clinic in obstetrics and gynaecology department in SVP Hospital Ahmedabad from May 2023 to December 2023 using Microsoft excel and SPSS version 23.Results: In this study all the females were with raised uterine artery PI in 18-20 weeks ultrasound among them 51.85% were normotensive in later pregnancy. 48.14% developed pre-eclampsia in later pregnancy. In our study the middle cerebral artery indices in doppler ultrasound showed increased diastolic flow (including brain sparing effect) among 37% of the patients. The umbilical artery doppler showed that 62.9% of subjects were having normal umbilical artery indices, 18.5% of the patients were having decreased diastolic flow, 11.1% of the patients were having reversal of diastolic flow and 7.4% of the patients were having absent end diastolic flowConclusions: Doppler study for fetal surveillance in pre-eclampsia is a very useful and non-invasive method and abnormal uterine artery velocimetry lead to the worse pregnancy outcomes in the present study. The knowledge of uterine and umbilical artery doppler is very helpful to improve pregnancy management and to identify and assess hypertensive disorder of the pregnancy at early gestational age compared to other antepartum test modalities.

ABSTRACT

The key assessment of the study was evaluating the gastro-protective properties of Barleria buxifolia root extract (REBB) in ulcerative rats. The roots of Barleria buxifolia have properties like antioxidant, anti-inflammatory, and other health benefits. Induction of gastric ulcers was done with aspirin (150 mg/kg, b.w., p.o) for 3 days and was accompanied by treatment with REBB (200 & 400 mg/kg orally) for 15 days. Ranitidine (20 mg/kg, orally) was received as the standard treatment for 14 days. Ulcer index, percent inhibition of ulceration, lipid peroxidation (LPO), TNF-? levels, and histopathological examination of the gastric mucosa were measured. Aspirin-induced stomach ulcers were seen in 100% of the groups, whereas other animal groups, aside from the control group possessed relatively comparable inductions. Ulcer number, ulcer index (p<0.01), and LPO (p<0.05) shown significant reduction in the 400mg/kg and Ranitidine (20mg/kg) when compared to Aspirin induced control group. Whereas the Ulcer score (p<0.001) and TNF-? (p<0.05) showed significant reduction in Ranitidine treated group but showed objectively improvement but statistically non-significant results in 200mg/kg and 400mg/kg REBB. Hence it was found that Baleria buxifolia root extract effectively mitigates aspirin-induced gastric ulceration in rats, underscoring its potential as a gastro protective agent.

ABSTRACT

Introducción y objetivo: Explorar las estrategias de prevención de la preeclampsia que se han propuesto a lo largo de la historia. Método: Revisión narrativa de la literatura sobre la evidencia científica histórica disponible entre 2016 y 2023 acerca de la aspirina y otras estrategias de prevención de la preeclampsia, en bases de datos bibliográficas computarizadas de estudios publicados en revistas indexadas. Resultados: Varios estudios confirman la efectividad de la aspirina para prevenir la preeclampsia en población de alto riesgo, siendo un medicamento con bajo riesgo de complicaciones, con mayor evidencia de efectividad si se inicia antes de las 16 semanas de gestación y con un aparente efecto dependiente de la dosis. Intervenciones como la disminución del consumo de sal, el reposo en cama, la suplementación con ácidos grasos, antioxidantes, L-arginina, zinc o magnesio, y el uso de diuréticos o de inhibidores de la bomba de protones, no han mostrado su utilidad en la prevención de la preeclampsia. Conclusiones: La aspirina a dosis baja es un medicamento seguro en el embarazo y efectivo para prevenir la preeclampsia en población de alto riesgo. Es la estrategia de prevención más ampliamente estudiada a lo largo de la historia para la disfunción endotelial durante la gestación.


Introduction and objective: To explore the different prevention strategies for preeclampsia that have been proposed throughout the history. Method: A narrative review of the historical, scientific evidence available between 2016 and 2021 on aspirin and other preeclampsia prevention strategies in computerized bibliographic databases of studies published in indexed journals. Results: Several studies confirm the effectiveness of aspirin to prevent preterm preeclampsia in high-risk populations, considering this as a safe drug with low risk of complications, with greater evidence of effectiveness when started before 16 weeks of gestation and apparently with a dose-dependent effect. Interventions such as reducing salt intake, bed rest, supplementation with fatty acids, antioxidants, L-arginine, zinc, magnesium, the use of diuretics or proton pump inhibitors have not shown its usefulness in the prevention of high risk preeclampsia patients. Conclusions: Low-dose aspirin is a safe drug in pregnancy and is effective to prevent preeclampsia in high-risk populations. Is the most widely studied throughout history prevention strategy for endothelial dysfunction during pregnancy.

ABSTRACT

Background: Low-dose aspirin is ineffective for primary prevention of cardiovascular events in people with body weight greater than 70kg. While the prevalent explanation for this is reduced platelet cyclooxygenase-1 (COX-1) inhibition at higher body weights, supporting data are limited, thereby demanding further investigation of the reason(s) underlying this observation. We propose that aspirin-mediated cyclooxygenase-2 (COX-2) acetylation and the resulting synthesis of 15-epi-lipoxin A4, a specialized pro-resolving mediator, is suboptimal in higher weight individuals, which may contribute to the clinical trial findings. Methods: To test this hypothesis, we are conducting a double-blind, placebo-controlled, randomized, mechanistic crossover trial. Healthy men and women exhibiting a wide range of body weights take 81mg aspirin and 325mg aspirin for 3 weeks each, following 3-week placebo run-in and wash-out phases. Our target sample size is 90 subjects, with a minimum of 72 completing all visits estimated to be necessary to achieve power adequate to test our primary hypothesis. Our primary endpoint is the difference in change in plasma 15-epi-lipoxin A4 occurring with each dose of aspirin. Secondary endpoints include lipid mediator profiles, serum bioactive lipid profiles, and other endpoints involved in the resolution of vascular inflammation. Conclusions: Study enrollment began in November 2021 and is ongoing. The results of this study will improve our understanding of the mechanisms underlying aspirin’s role(s) in the prevention of adverse cardiovascular outcomes. They may also lead to additional studies with the potential to inform dosing strategies for patients based on body weight. Trial registration: This trial is registered with ClinicalTrials.gov identifier NCT04697719.

ABSTRACT

Background: The objective of the current study was to analyse the anti-inflammatory effects of the aqueous extract of Stephania rotunda in experimental animals. Methods: It was an experimental study conducted in the experimental laboratory with 30 acclimatized healthy albino rats and mice divided into 5 groups namely A, B, C, D, and E fed with the aqueous extract of Stephania rotunda in laboratory conditions to assess the anti-inflammatory property using Carrageenan induced rat paw oedema for acute inflammation, granuloma pouch for sub-acute inflammation and Formaldehyde induced arthritis for chronic inflammation from 17th December 2019 to 22nd January 2021. Aspirin was taken as the standard drug. Data was analysed using Chi-square test. Results: In assessment for acute inflammation, the aqueous extract of Stephania rotunda in the doses of 500 mg/kg, 1000 mg/kg and 2000 mg/kg for groups B, C and D respectively produced 17.12%, 17.12% and 18.78% inhibition of paw oedema which was statistically significant when compared to 22.65% inhibition produced by 100mg/kg of the standard drug aspirin in group E. The groups B, C and D with the extract doses of 500mg/kg, 1000mg/kg and 2000mg/kg produced 43%, 60% and 77% inhibitions of exudate formation respectively which statistically was significant as compared to the Standard aspirin of group E which produced 62% inhibition of exudate formation. In chronic inflammation testing, both the extract and standard drugs produced highly significant inhibition of paw oedema when compared to inhibition produced by the Control. Conclusions: The aqueous extract of Stephania rotunda was found to be a potent anti-inflammatory drug when compared with Aspirin. Further tests are required in a larger scale so as to ascertain the effects for human consumption.

ABSTRACT

As patients undergoing orthopedic surgery are a high-risk group for venous thromboembolism (VTE), clinical guidelines suggest anticoagulant drugs for VTE prophylaxis during perioperative period. Global antithrombotic guidelines vary in recommendations for anticoagulant drugs, but there is a general consensus in favor of using low-molecular-weight heparin (LMWH) as the first choice for prophylaxis, followed by unfractionated heparin, fondaparinux, warfarin, aspirin, and other direct oral anticoagulants (DOACs). Of them, aspirin is an inexpensive, widely used antiplatelet drug with limited complications and clear efficacy in prevention of myocardial infarction, stroke, and certain specific cancers. It was also used early for venous thromboembolism prophylaxis in orthopedic patients after surgery. Clinical experience of orthopedic physicians in North America has shown the effectiveness of aspirin in VTE prevention over several decades so that aspirin continues to be used to this day, but its use for VTE prophylaxis is less common in Europe and Asia. Historically, the role and efficacy of aspirin in VTE prevention have been the subjects of considerable controversy, for the early and recent research findings contradict each other, and recommendations conflict in different guidelines. This review focuses on the advancements in clinical evidence and guideline recommendations regarding the use of aspirin for VTE prophylaxis in major orthopedic surgeries.

ABSTRACT

Abstract@#Aspirin (ASA) is widely used for primary and secondary prevention of cardiovascular disease (CVD), but its strategy of application is highly controversial. Meanwhile, in terms of ASA prevention strategies for CVD, countries around the world are different. The United States is becoming increasingly cautious, while the European Union tends to focus on the benefits of ASA clinical use. China is concerned about the effectiveness of ASA in preventing CVD in the elderly. This article reviews relevant literature published domestically and internationally from 2005 to 2024 for the application of ASA in CVD prevention, ASA prevention strategies for CVD in main countries and the application of ASA in special groups such as chronic disease patients, which provides a basis for improving ASA prevention strategies for CVD and standardizing clinical application of ASA in China.

ABSTRACT

ABSTRACT Objective: This study aims to evaluate aspirin as a chemical prophylaxis (200 mg) in total hip arthroplasty. Methods: the study compared two groups and used ultrasonography (USG) to screen for low-deep venous thrombosis. Group 1 received 600 mg (control), and Group 2 received 200 mg of (intervention), associated with the use of elastic compression stockings and early walking Results: fourteen patients were allocated to Group A (200mg), and 16 to Group B (600mg); in group A (200mg), 3 cases with thrombus below the popliteal vein were detected at the first USG examination. All of them are in the left lower limb (21.4%). In group B (600 mg), 5 cases were identified after the first exam (31.2%). All cases were asymptomatic and followed the protocol with prophylaxis only with Aspirin. Conclusion: In the statistical data, there were no differences in the presence of thrombus between the 200- and 600 mg groups, which is credited to using low-dose aspirin in low doses (200mg). Hematimetric levels returned to baseline levels and suggested there was no chronic or acute bleeding related to the use of aspirin. The manuscript was prepared according to the CONSORT guideline 2010. Level of Evidence I; Longitudinal Randomized Comparative Clinical Study.


RESUMO Objetivo: Este estudo pretende avaliar a aspirina como profilaxia química (200 mg) na artroplastia total do quadril. Métodos: estudo comparando dois grupos com diferentes doses de aspirina e utilizando a ultrassonografia (USG) para rastreamento da trombose venosa profunda baixa. O grupo 1, 650 mg ao dia de aspirina (controle) e o grupo 2, 200 mg de aspirina ao dia na mesma posologia (intervenção) e associados ao uso de meias elásticas de compressão e deambulação precoce. Resultados: quatorze pacientes foram alocados no grupo A (200 mg) e 16 no grupo B (650 mg). No grupo A foram detectados 3 casos com trombos abaixo da veia poplítea ao USG sendo 21,4%. Já no grupo B, 5 casos foram identificados após o primeiro exame (31,2%). Todos assintomáticos e sem sinais de sangramento ativo ou queda da hematimetria no momento da detecção dos trombos. Conclusão: os dados sugerem não haver diferença na incidência de trombo em ambos os grupos, não sendo a profilaxia com a aspirina dose-dependente. Os níveis hematimétricos retornaram aos níveis iniciais o que sugere não ter havido sangramento crônico ou agudo relacionado ao uso. Nível de Evidência I; Estudo Clínico Randomizado Longitudinal Comparativo.

ABSTRACT

Objective:To investigate the correlation between long-term use of low-dose aspirin and Helicobacter pylori(HP)infection in elderly people and its effectiveness on HP eradication and recurrence.Methods:A retrospective analysis was conducted on 2 834 elderly people aged 60 and above who underwent the C 13-or C 14-urea breath test(UBT)for the first time in the Physical Examination Center of the First Hospital of Lanzhou University between March 2010 and December 2019.According to the results of UBT, people were divided into an HP infection group with 1 510 patients and a non-HP infection group with 1 324 patients.Univariate and multivariate Logistic regression analysis were used to investigate the relationship between aspirin use and HP infection.Additionally, in a prospective case-control analysis, 544 elderly hypertensive patients diagnosed with HP infection between March 2015 and December 2020 were selected and divided into an aspirin group(402 cases)and an observation group(142 cases), based on whether aspirin was used.The aspirin group was further divided into a 1 to <2 years group(134 cases), a ≥2 to <5 years group(142 cases)and a ≥5 years group(126 cases)based on the duration of aspirin treatment.The rates of HP eradication, safety and one-year post-treatment HP recurrence with bismuth-containing quadruple therapy were compared. Results:The overall HP infection rate was 53.28%(1 510/2 834).Univariate analysis showed that the infection rate in women was higher than in men[56.86%(584/1 027) vs.51.25%(926/1 807), χ2=8.307, P=0.004].The infection rate in aspirin users was higher than in non-aspirin users[57.29%(920/1 606) vs.48.05%(590/1 228), χ2=23.866, P<0.001], with no significant difference between aspirin use for 1-<2 years, ≥2-<5 years and ≥5 years[60.22%(162/269) vs.56.4%(273/484) vs.56.86%(485/853), χ2=1.166, P=0.558].Fasting blood glucose levels in the HP infection group were higher than in the non-HP infection group[(5.92±1.78)mmol/L vs.(5.77±1.40)mmol/L, t=2.317, P=0.021].Multivariate Logistic regression analysis showed the risk of HP infection in women was higher than in men( OR=1.254, 95% CI: 1.075-1.464, P=0.004).Long-term aspirin use increased the risk of HP infection( OR=1.450, 95% CI: 1.249-1.684, P<0.001).Among the 544 cases selected for eradication therapy, 522 completed the treatment protocol, with 479 achieving successful eradication.The overall eradication rate was 91.76%(479/522)according to per-protocol(PP)analysis and 88.05%(479/544)according to intention-to-treat(ITT).After 1 year, 472 cases underwent reexamination, with an overall recurrence rate of 3.6%(17/472).There was no statistical significance in the eradication rate and recurrence rate among the groups with different durations of aspirin treatment and the observation group. Conclusions:Long-term use of low-dose aspirin increases the risk of HP infection in the elderly, but does not affect the eradication rate and one-year recurrence rate of bismuth-containing quadruple therapy.Therefore, periodic screening and eradication of HP should be performed.

ABSTRACT

OBJECTIVE To evaluate the clinical efficacy and safety of aspirin versus other anticoagulants in the prevention of thromboembolism after orthopedic surgery. METHODS Retrieved from PubMed, Embase, the Cochrane Library, CNKI, Wanfang data and VIP, randomized controlled trials (RCTs) and cohort studies about aspirin (trial group) versus other anticoagulants (control group) were collected during the inception and June 1st, 2023. After literature screening, data extraction and quality evaluation, the meta-analysis was conducted by using RevMan 5.4 software. RESULTS A total of 22 studies were included, involving 9 RCTs and 13 cohort studies. RCT results showed that the incidences of deep vein thrombosis (DVT) [RR=1.81, 95%CI(1.36, 2.40), P<0.000 1] and postoperative pulmonary embolism (PE) [RR=1.55, 95%CI(1.01, 2.40), P=0.05] in trial group were significantly higher than control group. There was no statistically significant difference in the incidences of postoperative massive bleeding, postoperative surgical site infection, all-cause death, or any bleeding after surgery between 2 groups. In the cohort study, the incidence of any bleeding in trial group was significantly lower than control group [RR=0.71,95%CI (0.64, 0.79), P<0.000 1], while the differences in other indicators were not statistically significant (P>0.05). The results of subgroup analysis based on different anticoagulants showed that in RCT, the incidences of DVT and PE after surgery in patients using low-molecular-weight heparin (LMWH) were significantly lower than using aspirin (P<0.05); in the cohort study, the incidences of DVT and PE after surgery were significantly lower in patients using direct oral anticoagulants (DOAC) than using aspirin (P<0.05). There was no statistically significant difference in the incidence of major bleeding between patients using aspirin and using DOAC and LWMH (P>0.05) in both RCT and cohort study. CONCLUSIONS Aspirin is equally safe as other anticoagulants for the prevention of thromboembolism after orthopedic surgery, but its efficacy may not be as good as other anticoagulants. After orthopedic surgery, other anticoagulants should be preferred to prevent venous thromboembolism, and aspirin should be carefully considered.

ABSTRACT

Objective To investigate the incidence and causes of medication errors(MEs)related to aspirin in the eld-erly(≥60 years old)of China,to provide data for targeted precautions,and to promote medication safety in the elderly.Methods Reports about aspirin-related MEs in the elderly were extracted from the National Monitoring Network for Clinical Safe Drug Medication from September 22,2012 to September 22,2022.The severity of errors,content of errors,where errors were made,the personnel who made these errors,and causes of errors were analyzed retrospectively and statistically.Results A total of 386 MEs reports were extracted,235 males and 151 females,with a median age of 70(60-98)years old.Regarding the severity of MEs,errors of class B were dominating(314 cases,81.35%).As for the severe MEs(9 cases,2.33%),5 cases of ME were as-sociated with bleeding.There are four patients suffering from gastrointestinal bleeding:one patient took aspirin three times a day,one patient broke off enteric-coated tablets,one patient took aspirin as acarbose mistakenly,one patient took aspirin with Xuesai-tong for long time.One patient had urinary urgency,but did not seek medical attention in time,then developed into visible hema-turia.Two patients missed taking aspirin led to stent thrombosis.One patient suffered from diarrhea after overdosing on 29 pills of aspirin by mistake.One patient with hyperuricemia had gout after taking aspirin.Among these 386 MEs,224(58.03%)cases were triggered by physicians,the first three error factors were frequency(multiple times a day),dosage(the dosage of enteric-coated tablets is not the whole tablet),and variety.Most of these MEs were due to a lack of knowledge or training,and fatigue.Regarding the MEs caused by pharmacists(87 cases,22.54%).Pharmacists identified 274 cases(70.98%)of errors.Conclusion When it comes to aspirin-related MEs,it ought to be noticed that the drug usage and dosage,drug interaction,and selection of drug varieties when combining with other diseases(such as atrial fibrillation and hyperuricemia).It is recommended that information construction be fortified to decrease the ME of the prescription link,and the clinicians be better informed of rational drug use.At the same time,patient medication education should be improved.

ABSTRACT

Abstract In low and middle-income countries such as Brazil, most maternal deaths are related to hypertensive complications. Preeclampsia is the leading cause of maternal mortality and morbidity. Significant proportion is associated with the following factors: lack of identification of high-risk women, lack of adequate prevention, difficulty in maintaining a high-risk prenatal follow-up, delayed diagnosis, insecurity and low use of magnesium sulphate, delayed pregnancy interruption and lack of postpartum follow-up of these high-risk cases. Four major actions are proposed to minimize this alarming clinical picture and reduce the mortality rates due to preeclampsia, called the "4 P Rule" (Adequate Prevention - Vigilant Prenatal Care - Timely Delivery (Parturition) - Safe Postpartum). From this simple "rule" we can open a range of important processes and reminders that may help in the guidance of preeclampsia management.

ABSTRACT

This case report discusses a 23-year-old male with recurrent priapism and its management. Priapism, defined as prolonged and painful penile erection, can lead to severe complications including permanent erectile dysfunction (ED) and penile deformities. The patient presented with priapism lasting 34 hours, despite previous spontaneous resolution of similar episodes. Initial treatment involved blood aspiration and irrigation with epinephrine, but the priapism recurred. Various shunting procedures were attempted, yet recurrent priapism persisted. Discussion highlights the challenge of maintaining shunt patency due to thrombosis and the importance of blood flow through the shunt for healing. The report introduces the notion of pre-operative aspirin and post-operative heparin to prevent shunt closure, though guidelines do not currently support this approach. Prior research suggests aspirin's positive impact on erectile function through enhanced nitric oxide production and platelet inhibition. The report concludes by recommending a treatment protocol involving initial aspiration and irrigation, followed by pre-operative aspirin, shunt surgery, and post-operative aspirin for 6 months to prevent shunt closure. This case emphasizes the need for further studies to validate the efficacy of anti-platelet therapy as part of priapism management.

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

Background: Medicinal plants are widely used in treating and preventing specific diseases and are known to play an important role in health care. Helianthus annuus is one of such plants whose therapeutic applications no doubt have numerous folkloric background. This study aimed at assessing Helianthus annuus methanol leaf extract for antiulcer and antimicrobial potentials Methods: The antiulcer activity was evaluated using aspirin, ethanol and histamine methods in Wistar rats, while the antimicrobial activity was carried out on selected microorganisms. The acute toxicity test and phytochemical screening of the extract were also conducted. Results: The methanol leaf extract exhibited significant (p<0.05 and p<0.01) antiulcer effect in both model. The ulcer protection effect of the extract is comparable to omeprazole. The extract also significantly inhibited the growth of test organisms. The acute toxicity test produced no lethality in rats, whereas the phytochemical analysis revealed the presence of alkaloids, saponins, tannins, flavonoids, terpenoids and steroids. Conclusions: The findings confirm the ethnomedicinal use of H. annuus leaf as a valuable natural agent for the treatment of ulcer and microbial infections.

ABSTRACT

Background: Pregnancy is associated with various complications such as pre-eclampsia, SGA, preterm birth etc. Low dose aspirin is a possible medication to minimize these adverse outcomes. The aim of this study was to evaluate the use of low dose aspirin for primary prevention of adverse pregnancy outcome. Material & Methods: This cross-sectional study was conducted in department of Gynaecology, North Bengal Medical College Hospital, Mirjapur Bkash Hospital, Mirjapur, Tangail, Bangladesh, during the period from June 2021 to August 2022. Total 200 pregnant women were included in this study. Results: In this study, the mean (±SD) age of the study subjects were 25.12 ± 5.49 years and 25.00 ± 4.83 years in LDA group and control group, respectively. There was no statistically significant (p>0.05) difference in age between the groups. The rate of caesarean section was higher in control group (68%) compared to LDA group (59%) but there was no statistically significant (p>0.05) difference among the groups. In our study, 8% pregnant women in LDA group and 19% pregnant women in control group had gestational hypertension, pre-eclampsia was seen in 6% and 13% pregnant women in LDA group and control group, respectively, preterm birth was seen in 8% and 17% pregnant women in LDA group and control group, respectively, SGA was seen in 19% and 32% pregnant women in LDA group and control group, respectively, and fetal distress was seen in 2% pregnant women in both LDA group and control group. There were statistically significant (p<0.05) differences in complications except fetal distress. Mean (±SD) neonatal birth weight was 2.88±1.03 kg and 2.74±0.85 kg in LDA group and control group, respectively and there was no statistically significant (p>0.05) difference. Conclusion: We found that low dose aspirin could significantly reduce the risk of adverse outcomes, especially for pre-eclampsia, SGA and preterm birth.

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

Background: The coronavirus disease (COVID-19) pandemic resulted in an unprecedent global response for the development of COVID-19 vaccines. However, as viral mutations continue to occur, potentially decreasing the efficacy of currently available vaccines, and inequity of vaccine access continues, identifying safe and effective drugs to minimise severity of COVID-19 disease remains a priority. Methods: We designed an adaptive individually randomized single blinded non identical placebo-controlled trial to evaluate the safety and efficacy of repurposing licenced treatments for COVID-19 patients in an African setting. The trial has two cohorts: Cohort 1 recruits mild and moderate COVID-19 cases and their household contacts. Cases are actively followed up for 14 days, with a final visit at day 28. There are two co-primary endpoints: clinical progression to severe-pneumonia and persistence of the virus at day 14. The primary endpoint for household contacts is infection during a 14-day follow-up period. Cohort 2 recruits hospitalized patients with severe COVID-19 associated pneumonia followed up actively until discharge or death, and passively until day 90, with a final visit. The primary endpoint is clinical progression or death. Conclusions: This randomized trial will contribute African-specific data to the global response to COVID-19. Besides the efficacy of drugs on clinical progression, the trial will provide information on the dynamics of intra-household transmission. Trial registration: This study is registered with Clinical Trials.gov with registration number NCT04703608 and with Pan African clinical trials registry with registration number PACTR202101544570971.

ABSTRACT

Abstract Background Pharmacogenetics promises better control of diseases such as cardiovascular disease (CVD). Acetylsalicylic acid, aspirin, prevents the formation of an activating agent of platelet aggregation and vasoconstriction, and it is used to prevent CVD. Nevertheless, patients may have treatment failure due to genetic variants that modify the metabolism of the drug causing aspirin resistance (AR). Objectives To realize a systematic literature review to determine the impact of genetic variants on AR. Methods Articles published in the MEDLINE/PubMed, Cochrane, Scopus, LILACS, and SCIELO databases were systematically screened. A total of 290 articles were identified and 269 articles were excluded because they did not comply with the previously established inclusion criteria. A total of 20 case-control studies and 1 cohort was included. Results The genetic variants rs1126643 (ITGA2), rs3842787 (PTGS1), rs20417 (PTGS2), and rs5918 (ITGB3) were the most studied. As for relevance, of the 64 genetic variants evaluated by the articles, 14 had statistical significance (p< 0.05; 95% confidence interval [CI]) in at least one article. Among them, the following have had unanimous results: rs1371097 (P2RY1), rs1045642 (MDR1), rs1051931 and rs7756935 (PLA2G7), rs2071746 (HO1), rs1131882 and rs4523 (TBXA2R), rs434473 (ALOX12), rs9315042 (ALOX5AP), and rs662 (PON1), while these differ in real interference in AR: rs5918 (ITGB3), rs2243093 (GP1BA), rs1330344 (PTGS1), and rs20417 (PTGS2). As study limitations, we highlight the nonuniform methodologies of the analyzed articles and population differences. Conclusion It is noteworthy that pharmacogenetics is an expanding area. Therefore, further studies are needed to better understand the association between genetic variants and AR.


Resumo Antecedentes A farmacogenética promete melhorar o controle de doenças como as cardiovasculares. O ácido acetilsalicílico, a aspirina, previne a formação de um agente ativador da agregação plaquetária e vasoconstrição e é usado na prevenção de tais doenças. No entanto, os pacientes podem ter falha no tratamento devido a variantes genéticas que modificam o metabolismo da droga causando resistência à aspirina (RA). Objetivos Realizar uma revisão sistemática da literatura para determinar o impacto das variantes genéticas na resistência à aspirina. Métodos Artigos publicados nos bancos de dados MEDLINE/PubMed, Cochrane, Scopus, LILACS e SCIELO foram sistematicamente selecionados. Foram identificados 290 artigos e, destes, 269 artigos foram excluídos por não atenderem aos critérios de inclusão previamente estabelecidos. Um total de 20 estudos caso-controles e 1 coorte foi incluído. Resultados As variantes genéticas rs1126643 (ITGA2), rs3842787 (PTGS1), rs20417 (PTGS2) e rs5918 (ITGB3) foram as mais estudadas. Quanto à relevância, das 64 variantes genéticas avaliadas pelos artigos, 14 tiveram significância estatística (p< 0,05; intervalo de confiança [IC] de 95%) em pelo menos um artigo. Entre eles, os seguintes tiveram resultados unânimes: rs1371097 (P2RY1), rs1045642 (MDR1), rs1051931 e rs7756935 (PLA2G7), rs2071746 (HO1), rs1131882 e rs4523 (TBXA2R), rs434473 (ALOX12), rs9315042 (ALOX5AP) e rs662 (PON1), enquanto estes diferiram na interferência real na RA: rs5918 (ITGB3), rs2243093 (GP1BA), rs1330344 (PTGS1) e rs20417 (PTGS2). Como limitações do estudo, destacam-se as metodologias não uniformes dos artigos analisados e as diferenças populacionais. Conclusão Vale ressaltar que a farmacogenética é uma área em expansão. Portanto, mais estudos são necessários para entender melhor a associação entre variantes genéticas e RA.
