Bleeding characteristics and mortality outcomes following ST-elevation myocardial infarction thrombolysis:a 5-year analysis in an Asian population

BACKGROUND:Bleeding outcomes are crucial primary safety endpoints in studies involving thrombolytic agents.This study aimed to determine the incidence,characteristics and mortality outcomes of bleeding following ST-elevation myocardial infarction(STEMI)thrombolysis in an Asian population.METHODS:This single-centre retrospective study included all STEMI patients who received thrombolytic therapy from 2016 to 2020 in a Malaysian tertiary hospital.Total population sampling was used in this study.The primary outcome was bleeding events post-thrombolysis,categorised using the Thrombolysis in Myocardial Infarction(TIMI)bleeding criteria.Inferential statistics were used to determine the associations between relevant variables.RESULTS:Data from 941 patients were analysed.A total of 156(16.6%)STEMI patients bled post-thrombolysis.Major,minor,and minimal TIMI occurred in 7(0.7%),17(1.8%),and 132(14.0%)patients,respectively.Age 65 years(P=0.031)and Malaysian Chinese(P=0.008)were associated with a higher incidence of bleeding post-thrombolysis.Conversely,foreigners(P=0.032)and current smoker(P=0.007)were associated with a lower incidence of bleeding.Both TIMI major(P<0.001)and TIMI minor(P<0.001)were associated with a higher incidence of all-cause in-hospital mortality among STEMI patients.TIMI minor bleeding was significantly higher in the streptokinase recipients.The bleeding sites were comparable between streptokinase and tenecteplase recipients,except for a significantly higher incidence of gastrointestinal bleeding in the streptokinase recipients(P=0.027).CONCLUSION:In our Asian population,the incidence of total bleeding events following STEMI thrombolysis is comparable to that previously reported.The development of TIMI major and minor bleeding complications is associated with higher mortality.

Effect of ramipril on progression of nonculprit lesions in patients with ST-elevation myocardial infarction after primary percutaneous coronary intervention

Objective To investigate the effect of ramipril on progression of nonculprit lesions in patients with ST-elevation myocardial infarction(STEMI) after primary percutaneous coronary intervention(PPCI). Methods A total of 200 patients(60.1 ± 11.3 years) with STEMI who underwent successful PPCI from January 2010 to December 2013 were enrolled in this study. All patients underwent PPCI as treatment for culprit lesions. Patients were divided into two groups according to the dosage of ramipril used at hospital discharge as follows: high dosage group(2.5–10 mg, q.d.) and low dosage group(1.25–2.5 mg, q.d.). Clinical and angiographic follow-up was performed for 12 months. The primary endpoint was clinically-driven percutaneous coronary intervention(PCI) for nonculprit lesions. The clinical and angiographic features were analyzed. Results Clinical and angiographic follow-up was performed with 87 patients in the high dosage group and 113 patients in the low dosage group. The numbers of patients who underwent additional PCI were six and 20 in the high and low dosage groups, respectively. The rate of having additional PCI performed was lower in the high dosage group than in the low dosage group(6.90% vs. 17.70%, P = 0.03). Conclusions A high dosage of ramipril may prevent progression of nonculprit lesions, which could be the major cause of recurrent PCI in patients with STEMI after PPCI.

Staged versus ＂one-time＂ multivessel intervention in elderly patients with non-ST-elevation acute coronary syndrome

Objective To evaluate the clinical outcomes of ＂one-time＂ versus staged multivessel stenting in elderly （〉 60 years）patients with non-ST-elevation acute coronary syndrome （NSTE-ACS） and multivessel disease （MVD）. Methods We analyzed data of consecutive NSTE-ACS patients with multivessel percutaneous coronary intervention （PCI） who were enrolled in General Hospital of Shenyang Military Region between 2008 and 2012. A total of 1090 eligible patients aged 〉 60 were further categorized into ＂one-time＂ group （n = 623） and staged PCI group （n = 467） according to intervention strategy. The primary endpoint was composite outcome of myocardial infarction （MI） or cardiac death during 3-year follow-up. Results The estimated 3-year composite rate of cardiac death or MI was 7.0% in the staged PCI group and 9.5% in the ＂one-time＂ group （P = 0.110）. Multivariate analysis confmned the benefit of staged PCI on the primary events in the elderly （HR： 0.638, 95% CI： 0.408-3.998, P = 0.049）. In a propensity score matched cohort, staged PCI was associated with lower rates of primary events （6.1% vs. 10.4%, P = 0.046） and MI （3.4% vs. 7.4%, P = 0.037） at three years. In addition, there were reduced trends in the stent thrombosis at 30 days （0.3% vs. 1.4%, P = 0.177） and at three years （1.1% vs. 2.4%, P = 0.199） in the staged PCI group. There was no significant difference in the 3-year target vessel revascularization （15.5% vs. 14.4%, P = 0.746）. Conclusions In elderly NSTE-ACS patients with MVD, staged PCI might be an optimal strategy associated with reduced long-term cardiac death or MI compared with ＂one-time＂ PCI strategy, which needs further confirmation.

Development of Primary Percutaneous Coronary Intervention as a National Reperfusion Strategy for Patients with ST-Elevation Myocardial Infarction and Assessment of Its Use in Egypt

Objective:Early treatment of acute ischemia of the heart by performing immediate percutaneous coronary intervention(PCI)to restore blood fl ow in patients with the clinical presentation of an acute coronary syndrome and more specifi cally with ST-elevation myocardial infarction(STEMI)can save lives.This study aims to identify the mean time(door to balloon time and fi rst contact to balloon time)to primary PCI for STEMI patients and to assess the percentage of primary PCI and its success rate in Egypt.Methods:A registry study of patients presenting to cardiac centers in Egypt was designed,where patients’basic characteristics,the treatment strategy,and the door to balloon time and the fi rst contact to balloon time were assessed.Results:One thousand six hundred fi fty STEMI patients with a mean age of 57 years were included in the study.Immediate transfer for primary PCI was the most used treatment strategy,representing 74.6%of all treatment strategies used.The door to balloon time and the fi rst contact to balloon time were 50 and 60 minutes,respectively,with a primary PCI success rate of 65.1%.Conclusion:The registry study results showed a marked improvement by implementation of the best treatment strategy with respect to the time factor to achieve a better outcome for STEMI patients in Egypt.

Impact of liver cirrhosis on ST-elevation myocardial infarction related shock and interventional management,a nationwide analysis

BACKGROUND Critical care is rapidly evolving with significant innovations to decrease hospital stays and costs.To our knowledge,there is limited data on factors that affect the length of stay and hospital charges in cirrhotic patients who present with STelevation myocardial infarction-related cardiogenic shock(SRCS).AIM To identify the factors that increase inpatient mortality,length of stay,and total hospital charges in patients with liver cirrhosis(LC)compared to those without LC.METHODS This study includes all adults over 18 from the National Inpatient Sample 2017 database.The study consists of two groups of patients,including SRCS with LC and without LC.Inpatient mortality,length of stay,and total hospital charges are the primary outcomes between the two groups.We used STATA 16 to perform statistical analysis.The Pearson's chi-square test compares the categorical variables.Propensity-matched scoring with univariate and multivariate logistic regression generated the odds ratios for inpatient mortality,length of stay,and resource utilization.RESULTS This study includes a total of 35798453 weighted hospitalized patients from the 2017 National Inpatient Sample.The two groups are SRCS without LC(n=758809)and SRCS with LC(n=11920).The majority of patients were Caucasian in both groups(67%vs 72%).The mean number of patients insured with Medicare was lower in the LC group(60%vs 56%)compared to the other group,and those who had at least three or more comorbidities(53%vs 90%)were significantly higher in the LC group compared to the non-LC group.Inpatient mortality was also considerably higher in the LC group(28.7%vs 10.63%).Length of Stay(LOS)is longer in the LC group compared to the non-LC group(9 vs 5.6).Similarly,total hospital charges are higher in patients with LC($147407.80 vs$113069.10,P≤0.05).Inpatient mortality is lower in the early percutaneous coronary intervention(PCI)group(OR:0.79<0.11),however,it is not statistically significant.Both early Impella(OR:1.73<0.05)and early extracorporeal membrane oxygenation(ECMO)(OR:3.10 P<0.05)in the LC group were associated with increased mortality.Early PCI(-2.57 P<0.05)and Impella(-3.25 P<0.05)were also both associated with shorter LOS compared to those who did not.Early ECMO does not impact the LOS;however,it does increase total hospital charge(addition of$24717.85,P<0.05).CONCLUSION LC is associated with a significantly increased inpatient mortality,length of stay,and total hospital charges in patients who develop SRCS.Rural and Non-teaching hospitals have significantly increased odds of extended hospital stays and higher adjusted total hospital charges.The Association of LC with worse outcomes outlines the essential need to monitor these patients closely and treat them early on with higher acuity care.Patients with early PCI had both shorter LOS and reduced inpatient mortality,while early Impella was associated with increased mortality and shorter LOS.Early ECMO is associated with increased mortality and higher total hospital charges.This finding should affect the decision to follow through with interventional management in this cohort of patients as it is associated with poor outcomes and immense resource utilization.

Serum uric acid in patients with acute ST-elevation myocardial infarction

BACKGROUND:Few studies investigated serum uric acid levels in patients with acute STelevation myocardial infarction(STEMI).The study was to assess the clinical value of serum uric acid levels in patients with acute ST-elevation myocardial infarction(STEMI).METHODS:Totally 502 consecutive patients with STEMI were retrospectively studied from January 2005 to December 2010.The level of serum lipid,echocardiographic data and in-hospital major adverse cardiovascular events(MACE) in patients with hyperuricemia(n=119) were compared with those in patients without hyperuricemia(n=383).The relationship between the level of serum uric acid and the degree of diseased coronary artery was analyzed.All data were analyzed with SPSS version 17.0 software for Student's t test,the Chi-square test and Pearson's correlation coefficient analysis.RESULTS:Serum uric acid level was positively correlated with serum triglyceride level.Hyperlipidemia was more common in hyperuricemia patients than in non-hyperuricemia patients(43.7%vs.33.7%,P=0.047),and serum triglyceride level was significantly higher in hyperuricemia patients(2.11±1.24 vs.1.78±1.38,P=0.014).But no significant association was observed between serum uric acid level and one or more diseased vessels(P>0.05).Left ventricular end-diastolic diameter(LVEDd) was larger in hyperuricemia patients than in non-hyperuricemia patients(53.52±6.19 vs.52.18±4.89,P=0.041).The higher rate of left systolic dysfunction and diastolic dysfunction was discovered in hyperuricemia patients(36.4%vs.15.1%,P<0.001;68.2%vs.55.8%,P=0.023).Also,hyperuricemia patients were more likely to have in-hospital MACE(P<0.05).CONCLUSIONS:Serum uric acid level is positively correlated with serum triglyceride level,but not with the severity of coronary artery disease.Hyperuricemia patients with STEMI tend to have a higher rate of left systolic dysfunction and diastolic dysfunction and more likely to have more in-hospital MACE.

Optimizing care for ST-elevation myocardial infarction patients： application of systems engineering

Timely reperfusion for patients with an ST-elevation myocardial infarction （STEMI） reduces myocardial cell loss resulting in preserved LV performance, a reduced incidence of congestive heart failure, and significantly lower early and late mortality, while conversely, any delay in reperfusion has a deleterious effect on morbidity and mortality.

Effect of fibrinolytic therapy on ST-elevation myocardial infarction clinical outcomes during the COVID-19 pandemic:A systematic review and meta-analysis

BACKGROUND ST-elevation myocardial infarction(STEMI)is the result of transmural ischemia of the myocardium and is associated with a high mortality rate.Primary percutaneous coronary intervention(PPCI)is the recommended first-line treatment strategy for patients with STEMI.The timely delivery of PPCI became extremely challenging for STEMI patients during the coronavirus disease 2019(COVID-19)pandemic,leading to a projected steep rise in mortality.These delays were overcome by the shift from first-line therapy and the development of modern fibrinolytic-based reperfusion.It is unclear whether fibrinolytic-based reperfusion therapy is effective in improving STEMI endpoints.AIM To determine the incidence of fibrinolytic therapy during the COVID-19 pandemic and its effects on STEMI clinical outcomes.METHODS PubMed,Google Scholar,Scopus,Web of Science,and Cochrane Central Register of Controlled Trials were queried from January 2020 up to February 2022 to identify studies investigating the effect of fibrinolytic therapy on the prognostic outcome of STEMI patients during the pandemic.Primary outcomes were the incidence of fibrinolysis and the risk of all-cause mortality.Data were meta-analyzed using the random effects model to derive odds ratios(OR)and 95%confidence intervals.Quality assessment was carried out using the Newcastle-Ottawa scale.RESULTS Fourteen studies including 50136 STEMI patients(n=15142 in the pandemic arm;n=34994 in the pre-pandemic arm)were included.The mean age was 61 years;79%were male,27%had type 2 diabetes,and 47%were smokers.Compared with the pre-pandemic period,there was a significantly increased overall incidence of fibrinolysis during the pandemic period[OR:1.80(1.18 to 2.75);I2=78%;P=0.00;GRADE:Very low].The incidence of fibrinolysis was not associated with the risk of all-cause mortality in any setting.The countries with a low-and middle-income status reported a higher incidence of fibrinolysis[OR:5.16(2.18 to 12.22);I2=81%;P=0.00;GRADE:Very low]and an increased risk of all-cause mortality in STEMI patients[OR:1.16(1.03 to 1.30);I2=0%;P=0.01;GRADE:Very low].Meta-regression analysis showed a positive correlation of hyperlipidemia(P=0.001)and hypertension(P<0.001)with all-cause mortality.CONCLUSION There is an increased incidence of fibrinolysis during the pandemic period,but it has no effect on the risk of all-cause mortality.The low-and middle-income status has a significant impact on the all-cause mortality rate and the incidence of fibrinolysis.

E/e’ as a Predictor of Short-Term Survival Following ST-Elevation Myocardial Infarction

Background: We examined the usefulness of tissue Doppler imaging in evaluating the diastolic dysfunction and assessed the prognostic value of ratio between early mitral inflow velocity and mitral annular early diastolic velocity (E/e’) in unselected patients with acute ST-elevation myocardial infarction (STEMI). Methods: Patients presenting with acute STEMI at Osmania General Hospital, Hyderabad, India between January-2012 and June-2012 were examined in this study. All patients underwent echocardiographic examination comprising Doppler assessment of transmitral flow velocities (peak E-wave velocity) and Doppler tissue imaging of the medial mitral valve annulus (e’). All patients were followed up for 6 months and all-cause mortality was measured as the study endpoint. Role of E/e’ ratio as a predictor of survival after acute STEMI was evaluated by a comparative analysis of patients with E/e’ ≤15 and >15. Results: A total of 50 patients with acute STEMI (mean age: 52.2 ± 13.2 years;80% males) were analyzed in this study. Of them, 23 (46%) patients had an E/e’ >15. Clinical parameters such as Killip class ≥2 as well as left ventricular ejection fraction of 15. Five (10%) patients died during the 6-month follow-up period. All deaths occurred among patients from the E/e’ >15 group, indicating that E/e’ is an effective predictor of overall survival. Conclusion: E/e’ ratio was identified as a strong predictor of survival after acute myocardial infarction and can be suitable for risk-stratification of patients in this setting. Further studies are warranted to substantiate the findings.

Correlation of serum iron levels with myocardial injury and pump failure in patients with acute ST-elevation myocardial infarction

Objective:To analyze the correlation of serum iron levels with myocardial injury and pump failure in patients with acute ST-elevation myocardial infarction. Methods:80 patients with acute ST-elevation myocardial infarction were divided into high iron group (serum iron≥8.95μmol/L) (n=43) and low iron group (serum iron<8.95μmol/L) (n=37) according to serum iron levels, differences in myocardial injury markers, ventricular remodeling indexes and pump failure-related indexes on admission were compared between two groups of patients, and the correlation of serum iron levels with myocardial damage and pump failure in patients with acute ST-elevation myocardial infarction was further analyzed. Results:Serum myocardial injury markers troponin I (cTnI), creatine kinase isoenzyme (CK-MB), myoglobin (Myo), ischemia modified albumin (IMA) and hydroxybutyrate dehydrogenase (HBDH) content of high iron group on admission were significantly lower than those of low iron group (P<0.05);left ventricular posterior wall thickness (LVPWT), left ventricular end-systolic interventricular septal thickness (IVST), left ventricular end-systolic volume (LVESV), left ventricular end-diastolic volume (LVEDV), end-systolic volume index (ESVI), end-diastolic volume index (EDVI), and the left ventricular mass index (LVMI) levels under color Doppler ultrasound were lower than those of low iron group (P<0.05);serum N-terminal pro-brain natriuretic peptide (NT-proBNP), galectin-3, adiponectin (APN), soluble P-selectin (sP-selectin) and Copeptin content were lower than those of low iron group (P<0.05). Pearson test showed that serum iron level was directly correlated with the degree of myocardial injury and pump failure in patients with acute ST-elevation myocardial infarction. Conclusions:Low serum iron levels is one of key factors causing severe cases and pump failure in STEMI patients, and early iron supplementation is expected to improve outcomes in STEMI patients with iron deficiency.

Characteristics of Emission Non-nulling Pulsars Through Simulation

We investigate the population and several properties of radio pulsars whose emission does not null(non-nulling)through simulation of a large pulsar sample.Emission from a pulsar is identified as non-nulling if(i)the emission does not cease across the whole pulse profile,and(ii)the emission is detectable.For(i),we adopt a model for switching in the plasma charge density,and emission persists if the charge density is non-zero.For(ii),we assume that detectable emission originates from source points where it is emitted tangentially to the magnetic field-line and parallel to the line-of-sight.We find that pulsars exhibiting non-nulling emission possess obliquity angles with an average of 42°.5,and almost half the samples maintain a duty cycle between 0.05 and 0.2.Furthermore,the pulsar population is not fixed but dependent on the obliquity angle,with the population peaking at 20°.In addition,three evolutionary phases are identified in the pulsar population as the obliquity angle evolves,with the majority of samples having an obliquity angle between 20°and 65°.Our results also suggest that emission from a pulsar may evolve between nulling and non-nulling during its lifetime.

Advances in treatment strategies for non–clear cell renal cell carcinoma

Renal cell carcinoma is the sixth most commonly diagnosed cancer in men and the tenth in women,with clear cell renal cell carcinoma accounting for nearly 75%of cases.The remaining 25%consists of non–clear cell renal cell carcinoma,a diverse and less prevalent group.Although current treatments for clear cell types are well-defined,progress in treating non–clear cell renal cell carcinoma has been limited owing to its heterogeneity and rarity,relying primarily on findings from small-scale phase Ⅱ clinical trials.This review examined recent advancements in the treatment of non–clear cell renal cell carcinoma,particularly in the areas of immunotherapy and targeted therapy.

目的探究不同非高密度脂蛋白胆固醇(non-HDL-C)水平初次急性心肌梗死患者的临床特征及载脂蛋白B(Apo B)和载脂蛋白A1(Apo A1)比值以及non-HDL-C与冠状动脉(冠脉)病变程度的相关性。方法选取2021年12月至2023年4月于重庆医科大学附属第一医院心内科入院治疗的首次诊断为急性心肌梗死且行冠脉造影的患者410例。计算Apo B/Apo A1比值及non-HDL-C,根据non-HDL-C三分位数分为低non-HDL-C组(≤2.89 mmol/L)、中non-HDL-C组(2.9~4.16 mmol/L)、高non-HDL-C组(≥4.17 mmol/L),比较三组患者一般临床资料及冠脉病变特点的差异性。另采用Spearman秩相关和二元Logistics回归分析non-HDL-C水平、Apo B/Apo A1对冠脉病变严重程度的影响。结果与低non-HDL-C组相比,中non-HDL-C组和高non-HDL-C组患者年龄更小(P<0.05);高non-HDL-C组较另外两组具有更高水平的体质指数(BMI)、三酰甘油(TG)、低密度脂蛋白胆固醇(LDL-C)、ApoB、ApoA1、ApoB/ApoA1、白蛋白、γ-谷酰转移酶、尿酸(P<0.05)。三组间左前降支病变、回旋支病变、多支血管病变、Gensini评分相比,差异有统计学意义(P<0.05)。偏相关分析显示Apo B/Apo A1和non-HDL-C均与多支血管病变、Gensini评分呈正相关(P<0.05);多因素二元Logistics回归分析显示ApoB/ApoA1比值(OR=3.149,95%CI:1.209~8.201,P=0.019)、non-HDL-C≥4.17 mmol/L(OR=4.199,95%CI:1.524~11.565,P=0.006)是多支血管病变的独立危险因素。结论在初次急性心肌梗死青年患者有冠脉病变或(冠状动脉粥样硬化性心脏病)危险因素中,更应关注ApoB/ApoA1及non-HDL-C,同时严格控制non-HDL-C是心肌梗死患者潜在的降脂目标。

基于Non stationary-CNN-Transformer的海浪有效波高预测

针对海浪有效波高序列波动性、随机性较强,难以精确预测以及模型无法高效挖掘深层特征间关系的问题,提出一种基于Non stationary-CNN-Transformer模型的海浪有效波高预测方法。首先,使用平稳化模块减弱海浪时序数据的非平稳性;其次,利用一维卷积神经网络(CNN)提取相关数据间的深层特征并构建特征向量;最后,使用含有平稳性注意力的Transformer描述波高序列的时间依赖性捕捉到序列之间的全局关系,通过逆归一化处理后获得有效波高预测结果。该方法可消除海浪时序数据的非平稳性,提升数据的预测效果,并具有优异的特征提取能力且善于处理大规模时间序列数据。在实验中应用澳大利亚的浮标实测数据,通过7组对比实验分别预测0.5、3、6、12和24 h的有效波高,对所提模型进行全方位、多角度的验证。算例研究结果表明,该文所提模型在不同时间段精度有明显提升。

The description of glucocorticoid and biologic usage in non-infectious uveitis is the main topic of this paper.

Investigating Non-Compliance with COVID-19 Vaccination through Hesitancy, Refusal, and Access Limitation: A Community-Based Survey from the Democratic Republic of the Congo

Introduction: Vaccination plays a pivotal role in mitigating the repercussions of the COVID-19 pandemic. However, vaccination campaigns encounter obstacles, especially in developing countries like the Democratic Republic of the Congo (DRC). This study aimed at investigating the roles of vaccine hesitancy, refusal, and access barriers, while identifying individual-level factors associated with non-vaccination in Mbujimayi, DRC. Methods: A community-based cross-sectional survey was conducted in three health districts and included 1496 residents. Attitudes and behaviors related to seeking COVID-19 vaccination were assessed using a standardized questionnaire. Hierarchical logistic regression modeling was used to assess factors potentially affecting non-compliance with vaccination. Results: Among participants (median age = 33, IQR = 23.3, M/F sex ratio = 0.7), 60% displayed misconceptions about COVID-19 or its vaccine, while only 35.2% perceived COVID-19 as a significant health threat. Vaccination coverage was estimated at 49.1% (95% CI: 47.5;52.6), with 71.8% of vaccinated individuals having received one dose. Among the unvaccinated individuals, 50.9% expressed no intention to be vaccinated in the future, citing hesitation (30.4%) or refusal (39.6%) mainly due to side effects or distrust of vaccines. Conversely, 32.7% of the unvaccinated persons expressed access barriers despite willingness to be vaccinated. Misconceptions about COVID-19 and its vaccines were the main drivers of vaccination non-compliance. Conclusion: These findings demonstrate significant vaccine non-compliance driven by hesitancy, refusal, and access barriers. Strategies to enhance vaccination coverage and pandemic preparedness should address misconceptions, sociodemographic barriers, and geographic disparities.

The Interventional Capacity of Community Health Volunteers for Screening and Linkages of Non-Communicable Diseases in Nyeri County, Kenya

Non-communicable diseases (NCDs) account for 63% of mortalities. Approximately 80% of these NCD-related deaths occur in LMICs. A quasi-experimental study utilizing a non-equivalent pre-and post-test was conducted from May 2022 to March 2023 with 370 study participants. Multistage cluster and random sampling were used to select ten community units, and therefore, 150 CHVs were chosen for the control unit, and 150 were used to form the interventional group. Data was collected from the KOBO app. Six (6) homogenous FGDs comprised ten members, and 10 KII were conducted across study sites. Quantitative data was analyzed using SPSS version 28.0, and qualitative data was audio-recorded, transcribed, and analyzed via N-Vivo 12. The study shows that 59.3% of respondents have minimal information, and 92.7% (n = 139) have no clear understanding of NCDs, with a pre-intervention capacity of 48.8%. Independent sample t-test showed a significant difference in capacity from a pre-intervention average of 48.75 (SD ± 5.7)%, which increased to 68.28 (SD ± 7.6)%, p < 0.001. A well-designed community interventional model plays a pivotal role in grassroots healthcare delivery but requires optimization for NCD management.

Roles of Community Pharmacists in Screening and Disseminating of Information about Non-Steroidal Anti-Inflammatory Drugs Risks: Implications for Drug Safety Assessment

Background: The increasing use of non-steroidal anti-inflammatory drugs (NSAIDs) both on prescription and over the counter raises a major global health concern because of the risks associated with their use if no proper guidance is given by the health care provider. This study assessed the roles of community pharmacists in screening and disseminating information about the risks associated with NSAID use in Zambia. Methodology: This was a national cross-sectional study in which a structured self-administered questionnaire was administered to 245 registered community pharmacists in Zambia. Stata/BE, version 15.1 (Stata Corporation, College Station, Texas, USA) and multivariate logistic regression model was used to determine factors associated with information dissemination about ADRs of NS-NSAIDs. Results: 231 of the 245 distributed questionnaires were returned giving a response rate of 94.3%. All (100%) participating community pharmacists claimed to have practiced dispensing NSAIDs. However, only 26 (11.0%) and 71 (30.8%) regularly screened for risk factor of selective COX-2 NSAIDS (SC2-NSAIDS) and non-selective NSAIDS (NS-NSAIDs) respectively. Information dissemination on adverse drug reactions (ADRs) of SC2-NSAIDS was regularly provided by only 22 (9.5%) of pharmacists while that of NS-NSAIDs was regularly provided by 49 (21.2%). In the multivariate logistic regression model, being the owner of a pharmacy (AOR: 5.4, CI: 1.84 - 16.4) was significantly associated with information dissemination about ADRs of NS-NSAIDs while an hour increase in the working hours per day (AOR: 0.9, CI: 0.64 - 0.95) was associated with less likelihood of information dissemination. Conclusion: Pharmacists working in community pharmacies in Zambia did not regularly screen and disseminate information about the risks associated with NSAID use. Therefore, pharmacists should be able to screen and monitor patients at risk and be aware of the majority of risk factors while dispensing NSAIDs to minimize the associated complications.

Primary Non-Hodgkin’s Malignant Lymphoma of the Uterus at the Reference Hospital of Maradi/Niger: A Case Report

Malignant non-Hodgkins lymphoma (MHNL) of the uterus is uncommon. We report a case diagnosed on the basis of histologic and immunohistochemical studies of a hysterectomy specimen induced by a very painful pelvic mass in a 50-year-old patient with no previous history of the disease. It was classified as Ann Arbor IV Bb after imaging, given the medullary infiltration and signs of clinical and biological evolutivity: the patient had received two courses of chemotherapy, CHOP protocol. She died 23 days after the second treatment due to a hypertensive crisis.

A Study on Near-Infrared Non-Invasive Blood Glucose Concentration Regression Prediction Based on PSO-MKL-SVR

To improve the accuracy of predicting non-invasive blood glucose concentration in the near-infrared spectrum, we utilized the Particle Swarm Optimization (PSO) algorithm to optimize hyperparameters for the Multi-Kernel Learning Support Vector Machine (MKL-SVR). With these optimized hyperparameters, we established a non-invasive blood glucose regression model, referred to as the PSO-MKL-SVR model. Subsequently, we conducted a comparative analysis between the PSO-MKL-SVR model and the PSO-SVR model. In a dataset comprising ten volunteers, the PSO-MKL-SVR model exhibited significant precision improvements, including a 16.03% reduction in Mean Square Error and a 0.29% increase in the Squared Correlation Coefficient. Moreover, there was a 0.14% higher probability of the Clark’s Error Grid Analysis falling within Zone A. Additionally, the PSO-MKL-SVR model demonstrated a faster operational speed compared to the PSO-SVR model.
