Management of Acquired Aural Atresia and Stenosis: A Case Series.

Background: Acquired aural atresia and aural stenosis have high recurrence rates, which are challenging for ear, nose, and throat surgeons. This study aimed to discuss the management of acquired aural atresia and aural stenosis to obtain favorable outcomes. Methods: Four representative cases of different etiologies are presented, and a related literature review was conducted. Results: Four patients aged 11 to 63 years were included in this study. Every patient with long-term follow-up (≥1 year) achieved favorable outcomes via pre- and postoperative management. Conclusion: Prevention in clinical practice is conducive to decreasing the incidence of acquired aural stenosis and aural atresia. Surgical techniques and postoperative management determine operative success. External auditory canal support is indispensable, and local corticosteroid injections in the early stage are beneficial for the management of restenosis.

Effect of diabetes mellitus type 2 and sulfonylurea on colorectal cancer development: a case-control study

Background and aimsColorectal cancer (CRC) is a significant global health concern, with studies estimating a rise in new cases to 2.5 million by 2035. Type 2 diabetes (T2D) is also a growing issue, with an estimated 642 million adults affected by 2040. However, the relationship between T2D, its medications, and CRC remains unclear.Materials and methodsThis case-control study includes 810 controls without CRC and 684 cases with CRC admitted to Rasoul-Akram and Firouzgar Hospitals from September 2019 to 2023. Adjusted and unadjusted odds ratios (OR) were calculated to investigate the effect of T2D and sulfonylurea consumption on the chance of CRC development, using univariate and multivariate logistic regression analyses. The relationship between T2D and the clinicopathological features of the tumor was investigated.ResultsThe results show that the effect of T2D on CRC is significant based on unadjusted OR (OR = 1.39, CI = 1.07, 1.81) and insignificant in adjusted OR (OR = 0.67, CI = 0.37, 1.20). The effect of sulfonylurea consumption on CRC was significant in both unadjusted (OR = 2.39, CI = 1.40, 4.09) and adjusted ORs (OR = 2.35, CI = 1.12, 4.91). All analyses related to the relationship between T2D and tumor clinicopathological characteristics were insignificant.ConclusionThis study found an insignificant association between type 2 diabetes and the chance of CRC development in an adjusted state. Sulfonylurea consumption was also associated with a higher chance of CRC development among patients with T2D. These findings have implications for clinical practice and public health strategies in CRC prevention for patients with T2D.

Effective prevention in clinical practice may save human capital loss: Real-world evidence from Taiwan's National Health Insurance

Background/PurposeEffective prevention could protect the health of the workforce, save human capital loss, and maintain employee productivity as well as economic growth. MethodsUsing real-world data of patients with end-stage kidney disease (ESKD) and lung cancer, we multiplied their lifetime survival functions with employment ratios and working salaries to estimate the lifetime employment durations and earnings. They were compared with corresponding age-, sex-, and calendar year-matched referents to assess the differences in loss of lifetime employment duration and earnings. From 2000 to 2017, 83,358 patients with end-stage kidney disease (ESKD) were associated with 32–66% lifetime productivity losses. Similarly, we collected 24,904 incident cases of lung adenocarcinoma during 2011–2018 and estimated the potential savings in human capital due to early detection. Based on the evolving trends of ESKD incidence rates in Taiwan, we calculated the lifetime human capital losses of ESKD patients in GDP (gross domestic product) percentages during 2000–2020. ResultsThe aggregate lifetime productivity losses of ESKD in terms of GDP% varied between 0.000398% and 0.01% for male patients and between 0.0001% and 0.009% for female patients. The younger the patients, the bigger the losses in GDP%. Similarly, early detection of lung adenocarcinoma saved lives and productivity to some extent. ConclusionsSuccessful prevention of catastrophic illnesses at early stages would save the lifetime employment duration and productivity of the workforce. Future reform on the NHI could consider closer coordination between public health and healthcare organizations, focusing on effective prevention of diseases and complications to save productivity loss.

A digital twin approach for stroke risk assessment in Atrial Fibrillation Patients

Atrial fibrillation (AF) is associated with a fivefold increased risk of cerebrovascular events, contributing to 15–18 % of all strokes. Stroke prevention in clinical practice is typically guided by the CHA2DS2-VASc score, which depends on general clinical risk factors but falls short in predicting risk at an individual patient level. In this study, we introduce a digital twin model of the left atrium (LA) combined with computational fluid dynamics (CFD) simulations to enhance personalized stroke risk assessment. Simulations were performed on patient-specific dynamic LA models in sinus rhythm (SR) across three patient groups: 10 controls (CTRL), 10 with paroxysmal AF (PAR-AF), and 10 with persistent AF (PER-AF). Blood flow velocity and areas susceptible to thrombogenesis, based on several factors including endothelial damage, were identified in the left atrial appendage (LAA). In general, control subjects exhibited higher average blood velocity in both the LAA and its ostium (0.11 ± 0.03 m/s and 0.28 ± 0.05 m/s, respectively) compared to those with AF. In the AF groups, the velocities were lower (LAA: PAR-AF 0.05 ± 0.02 m/s, PER-AF 0.04 ± 0.02 m/s; LAA ostium: PAR-AF 0.14 ± 0.03 m/s, PER-AF 0.11 ± 0.04 m/s). CFD analysis revealed that endothelial cell activation potential (ECAP) was significantly higher in AF patients (PAR-AF: 3.96 ± 3.28 Pa⁻1, PER-AF: 4.77 ± 2.08 Pa⁻1) compared to controls (0.93 ± 0.63 Pa⁻1). These findings suggest that AF patients experience slower and more oscillatory blood flow in the LAA, increasing their risk of thrombosis. Additionally, blood tends to stagnate within the LAA, further raising the likelihood of clot formation. This proposed method could be used to enhance stroke risk stratification in AF patients by incorporating an index that integrates blood velocity-derived parameters.

Current Science and Practice of Surgical and Nonsurgical Opportunities for Ovarian Cancer Prevention.

Due to improved understanding of ovarian cancer pathogenesis, we have an unprecedented chance to decrease the burden of disease by maximizing opportunities for prevention. Innovations in surgical options for prevention stem from the discovery that many cases directly or indirectly arise from the fallopian tube. Surgical prevention with salpingectomy alone decreases risk by ≥50%. Effective hormonal and nonhormonal chemopreventive agents are also available. Risk stratification is key to ensuring that options for prevention are appropriately matched to individual risk profile. This evidence-based review provides a critical appraisal of the translational health research endeavors supporting ovarian cancer prevention in clinical practice.

Mobile health apps for cardiovascular risk assessment: a systematic review.

mHealth apps (MHA) are emerging as promising tools for cardiovascular risk assessment, but few meet the standards required for clinical use. We aim to evaluate the quality and functionality of mHealth apps for cardiovascular risk assessment by healthcare professionals. We conducted a systematic review of MHA for cardiovascular risk assessment in the Apple Store, Play Store, and Microsoft Store until August 2023. Our eligibility criteria were based on the 2021 European Society Cardiology Guidelines on Cardiovascular Disease Prevention in Clinical Practice, the Framingham Risk Score, and the Atherosclerotic Cardiovascular Disease score. Our protocol was drafted using the Preferred Reporting items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. To assess quality, we used the validated Mobile Apps Rating Scale (MARS) score, which includes 19 items across four objective scales (engagement, functionality, aesthetics, and information quality) and one additional subjective scale. For functionality evaluation, we used the IMS Institute for Healthcare Informatics functionality scale. We performed data synthesis by generating descriptive statistics. A total of 18 MHA were included in the review. The most common scores used were the Framingham score, ASCVD score, and Score 2. Only six apps achieved an overall score of 4 or greater in the MARS evaluation. The MHA with the highest MARS score was ESC CVD Risk Calculation (5 points), followed by ASCVD Risk Estimator Plus (4.9 points). In the IMS scale, four MHA had a high functionality score: ASCVD Risk Estimator Plus (5 points), ESC CVD Risk Calculation (5 points), MDCalc Medical Calculator (4 points), and Calculate by QsMD (4 points). A gap exists in the availability of high-quality MHA designed for healthcare professionals to facilitate shared decision-making in cardiovascular risk assessment.

Role of Phytocompounds for Effective Management of Migraine: Current and Future Prospectives.

Migraine is one of the most painful and debilitating conditions, which is characterized by a pulsating headache. Many therapeutic strategies are being used to prevent and treat the symptoms and underlying pathology. A relatively high number of different medications are currently being used for migraine prevention in clinical practice. However, these compounds were initially developed for other indications and were different in their mechanisms of action. This review mainly summarized all the conventional and phytocompounds currently present for the treatment of migraine. Further, we also discussed therapeutic potential and clinical studies of natural compounds for the treatment of migraine prophylaxis under various chemical categories like flavonoids, polyphenols, alkaloids, glycosides, terpenoids, and lactone, acid, and alcohol.

HOCl Production Modelling for an Electrochemical Catheter

Intravascular catheters are used in critically ill patients to deliver fluids and lifesaving medications, and for hemodynamic monitoring. These catheters are at risk for infection, especially when in place for prolonged periods of time. The management of catheter-related infections are challenged by both the presence of biofilms and the frequent association with multidrug-resistant organisms. Efforts to mitigate central line-associated bloodstream infections (CLABSIs) have focused on preventive measures. Several strategies to prevent intraluminally sourced CLABSI have been developed and used, including antimicrobial agent locks and antimicrobial-impregnated catheter lumens. Although antimicrobial locks have reduced CLABSI rates, this strategy is prone to complications, including resistance selection, allergic reactions, catheter damage, and host toxicity due to the high concentrations of agents needed. Largely because of these factors, antimicrobial locks are infrequently used for CLABSI prevention in clinical practice. Antimicrobial impregnated catheter lumens have also shown variable effects against CLABSI and are likewise not regularly used. Therefore. innovative therapeutic solutions are necessary, especially those that allow catheter retention. In this context, the integration of electrochemical technologies for hypochlorous acid (HOCl) production within intravascular catheters emerges as a promising strategy to combat CLABSIs. HOCl is a strong oxidizing agent that damages microbial cells by interacting with lipids, nucleic acids, sulfur-containing amino acids, and membrane components. It is found in all mammals as an endogenous substance produced by the immune system to protect the body from pathogens. In this study, electrochemical generation of HOCl in an electrochemical catheter (e-catheter) was simulated using a model called Electrochemical Hypochlorous Acid Production (EHAP), implemented in COMSOL Multiphysics®. The e-catheter has two components, a hub and a tube, both filled with 0.9% saline solution. Titanium wires are used as working and counter electrodes.The model was used to define critical variables that may impact HOCl generation and distribution. In addition to predicting HOCl concentrations, the EHAP model was used to monitor effects of 1) a waiting period after constant polarization, 2) operational voltage, 3) working electrode length and 4) working electrode surface area. Findings using the EHAP model revealed the following: 1) Diffusion limitations predominate when the electrodes are localized to the hub, yielding a lower HOCl concentration in the tube compared to the hub. Increasing the voltage between the working and the reference electrodes increases HOCl generation, however concentrations are not enough to deliver HOCl to the tube. 2) HOCl concentrations are higher in the tube compared to hub when the working electrode extends the entire length of the tube. 3) HOCl concentration distributions can be tuned by changing the surface area of the working electrode within different compartments of the e-catheter.

Association between the C-reactive protein-triglyceride glucose index and erectile dysfunction in US males: results from NHANES 2001-2004.

The C-reactive protein-triglyceride glucose index (CTI) is emerging as a novel indicator for comprehensively assessing the severity of both inflammation and insulin resistance. However, the association between CTI and erectile dysfunction (ED) remains largely unexplored. Participant data for this study were sourced from NHANES 2001-2004, with exclusion criteria applied to those lacking information on clinical variables. The CTI was defined as 0.412*Ln (CRP) + ln [T.G. (mg/dL) × FPG (mg/dL)/2]. Weighted univariable and multivariable logistic regression models were utilized to examine the correlation between the CTI and ED, assessing the CTI as both a continuous and categorical variable (quartile). Moreover, subgroup analyses were conducted to pinpoint sensitive populations, and interaction analysis was performed to validate the findings. A total of 1502 participants were included in the final analysis, encompassing 302 with ED and 1200 without ED. After adjusting for potential confounders, the CTI was positively associated with ED incidence (OR = 1.56, 95% CI: 1.27-1.90, P = 0.002). The fourth quartile of the CTI significantly increased the incidence of ED (OR = 2.69, 95% CI: 1.07-6.74, P = 0.04), and the lowest quartile of CTI was used as the reference. The dose-response curve revealed a positive linear relationship between the CTI and the incidence of ED. Subgroup analysis confirmed the consistent positive relationship between the CTI and ED. The interaction test indicated no significant impact on this association. Finally, a sensitivity analysis was performed to verify the significant positive correlation between the CTI and severe ED (OR = 1.44, 95% CI: 1.19-1.76, P = 0.004). Our national data indicate that a greater CTI is positively linked to an increased risk of ED in US men, suggesting its potential for use in clinical practice for ED prevention or early intervention. Additional large-scale prospective studies are warranted to substantiate the causative relationship between CTI and ED.

Acute kidney injury after non-cardiac major surgery: has it reduced?

ABSTRACT Background It remains unclear whether the incidence of post-operative acute kidney injury (PO-AKI) has been reduced despite the recent emphasis on its early recognition and prevention in clinical practice. We aimed to investigate the trend in the incidence of PO-AKI and to identify the associated factors affecting its changes. Methods We gathered clinical data from patients who underwent non-cardiac major surgeries at three referral hospitals from 2005 to 2020. PO-AKI was defined as KDIGO AKI criteria within 7 days after surgery. Severe PO-AKI (S-PO-AKI) was defined as stage 2 or 3 AKI. The temporal change of PO-AKI was evaluated by joinpoint regression analysis and multivariable logistic regression based on a 3-year interval. Results Among 138 235 patients, 8156 (5.9%) PO-AKI and 1127 (0.8%) S-PO-AKI occurred, respectively. The patients enrolled in recent years were older and more were women. They had more comorbidities and a higher PO-AKI risk compared with those included in past years. As time passed, the PO-AKI incidence decreased from 8.6% in 2005–07 to 5.1% in 2017–20, whereas S-PO-AKI incidence did not change (0.8% to 0.9%). In joinpoint analysis, PO-AKI incidence tended to decrease with annual percentage change (APC) of –4.2% per year [95% confidence interval (CI) –5.5% to –2.8%, P-value <.001), although S-PO-AKI did not (APC 0.9%, 95% CI –1.1 to 2.9%, P-value = .347). Similarly, the overall PO-AKI incidence decreased but S-PO-AKI did not, even after adjusting covariables. Conclusion The incidence of PO-AKI has decreased recently despite the increase in known risk factors; however, the incidence of S-PO-AKI has not decreased in recent years.

Primary prevention of venous thromboembolism with low molecular weight heparins in surgical patients – 2024: Council of Experts resolution

On March 15, 2024, in Moscow, the Russian Phlebological Association and the National Association of Specialists in Thrombosis, Clinical Hemostasiology and Hemorheology organized a meeting of the Council of Experts during the Russian Forum on Thrombosis and Hemostasis on the acute issues of venous thromboembolism (VTE) primary prevention using low molecular weight heparins (LMWH) in surgical patients with different body weight. The participants reviewed the relevance and prevalence of this problem in surgical practice, discussed risk factors and the frequency of VTE development, including bleeding in the postoperative period, and the Caprini risk score for complications. The discussion also focused on standard and personalized LMWH doses for primary prophylaxis of VTE in the perioperative period in surgical patients, depending on body weight, and the role of laboratory tests, including assessment of LMWH anti-Xa activity for monitoring the efficacy and safety of VTE primary prevention in clinical practice.

PRECLINICAL VASCULAR ORGAN DAMAGE AND VASCULAR AGEING ASSESMENT IN NON-ALCOHOLIC FATTY LIVER DISEASE AND METABOLIC ASSOCIATED FATTY LIVER DISEASE PATIENTS

Objective: Non-alcoholic fatty liver disease (NAFLD) and metabolic associated fatty liver disease (MAFLD) are a growing health problem, with a growing prevalence due to its association with metabolic syndrome and diabetes. It is known to be a risk factor for the development of cirrhosis and hepatocarcinoma, but it is also known to be an important cardiovascular risk factor. The aim of this study is to assess the burden of preclinical vascular organ damage. Design and method: The study enrolled 80 consecutive patients (mean age 63.3±15.0) who underwent hepatological evaluation in our department, with evaluation of liver fibrosis score (APRI score, FIB-4) and liver stiffness, and quantification of cardiovascular risk according to Guidelines (2021 ESC Guidelines on cardiovascular disease prevention in clinical practice). Carotid atherosclerotic burden was evaluated by B-mode ultrasound in each segment (common, bulb, internal), bilaterally, and expressed as mean of maximum IMT (M-MAX), right common carotid artery distensibility and stiffness (CardioVascular Suite 4, Quipu, Italy). Aortic stiffness was evaluated as carotid-femoral pulse wave velocity (PWV), measured by applanation tonometry (PulsePen DiaTecne, Italy), with calculation of vascular ageing. Results: We found no significant correlation between ultrasound or tonometry parameters and liver stiffness and fibrosis scores. VPWV was significantly above upper limit of normal of 10 m/s (11.6±6.0 m/s, p=0.02), and the percentiles for age were significantly higher than 50th (61.7±25.1, p<0.001), with 52,5% of patients showing increased PWV. Similarly, M-MAX was higher than the upper normality level of 0.9 mm (1.09±0.30 mm, p<0.001). 70% of patients had an increased M-MAX. Vascular age based on arterial stiffness resulted significantly higher than biological age (mean difference 4.6 years, p<0.001). 76.2% (71/80) of the overall cohort and 45,2% (14/31) of patients classified as low risk showed at least one type of vascular organ damage. Conclusions: Patients with NAFLD or MAFLD showed a large prevalence of arterial stiffening and increased IMT and an enhanced vascular ageing, even among those classified at low cardiovascular risk according to Guidelines. Vascular organ damage evaluation could be useful to identify preclinical organ damage in these patients

Impact of a program encouraging prevention in primary care on a daily and opportunistic basis

In France, clinical preventive practices are still underdeveloped and formalized, notably due to a lack of guidelines, despite the fact that a proactive and systematic prevention and health promotion strategy involving all healthcare professionals seems essential. The P3C program aims to encourage preventive clinical practices among healthcare professionals, and thus contribute to the emergence of a common culture of prevention.

Risk Management and Patient Safety in the Artificial Intelligence Era: A Systematic Review.

Healthcare systems represent complex organizations within which multiple factors (physical environment, human factor, technological devices, quality of care) interconnect to form a dense network whose imbalance is potentially able to compromise patient safety. In this scenario, the need for hospitals to expand reactive and proactive clinical risk management programs is easily understood, and artificial intelligence fits well in this context. This systematic review aims to investigate the state of the art regarding the impact of AI on clinical risk management processes. To simplify the analysis of the review outcomes and to motivate future standardized comparisons with any subsequent studies, the findings of the present review will be grouped according to the possibility of applying AI in the prevention of the different incident type groups as defined by the ICPS. On 3 November 2023, a systematic review of the literature according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines was carried out using the SCOPUS and Medline (via PubMed) databases. A total of 297 articles were identified. After the selection process, 36 articles were included in the present systematic review. The studies included in this review allowed for the identification of three main "incident type" domains: clinical process, healthcare-associated infection, and medication. Another relevant application of AI in clinical risk management concerns the topic of incident reporting. This review highlighted that AI can be applied transversely in various clinical contexts to enhance patient safety and facilitate the identification of errors. It appears to be a promising tool to improve clinical risk management, although its use requires human supervision and cannot completely replace human skills. To facilitate the analysis of the present review outcome and to enable comparison with future systematic reviews, it was deemed useful to refer to a pre-existing taxonomy for the identification of adverse events. However, the results of the present study highlighted the usefulness of AI not only for risk prevention in clinical practice, but also in improving the use of an essential risk identification tool, which is incident reporting. For this reason, the taxonomy of the areas of application of AI to clinical risk processes should include an additional class relating to risk identification and analysis tools. For this purpose, it was considered convenient to use ICPS classification.

Prevention of Preeclampsia in Saudi Arabia: Knowledge about Risk Factors and Aspirin Use among Obstetrical Care Physicians - A National Survey

Objectives: To assess the level of awareness among obstetrical care providers about preeclampsia prevention including risk factors, good practice in aspirin prophylaxis, and to analyze the associated factors. Methods: A cross-sectional study conducted among gynecologists and obstetricians, maternal and fetal medicine specialists, and internal or family medicine physicians working in public or private care centers whom involved in obstetric care in Saudi Arabia. An online-administered questionnaire was designed to assess familiarity of aspirin role in prevention of preeclampsia and fetal growth restriction including proper dose, timing of intake, gestational age to start and discontinuation of treatment as well as the risk factors of PE among set of 13 conditions. An awareness score was calculated and divided into two levels: adequate and inadequate familiarity and knowledge. Practice in PE prevention and attitude towards aspirin use, in addition to participants’ demographic and professional factors, were investigated and analyzed as profound factors. Results: Hundred sixty physicians were participated, 85% were obstetrician/gynecologists and 13.1 were maternal fetal medicine Specialists. Less than half of participants have adequate knowledge and awareness in aspirin role and a minority provided correct answers regarding the recommended aspiring dose, timing of intake, gestational age to start and discontinuation of treatment. However, knowledge about preeclampsia risk factors was relatively acceptable. Maternal fetal medicine specialist and physicians working in teaching hospitals were remarkably with better knowledge compared to their respective counterparts in primary and secondary centers. The existence of institutional guidelines about ASA use in pregnancy did not improve the knowledge level. Conclusion: The overall familiarity and knowledge in that regard was relatively poor, associating misconceptions about the risk factors and substantial gaps regarding the optimal timing and prescribing practice. Formal and continuous medical education curricula should be reviewed to promote good clinical practice in preeclampsia prevention as an essential dimension of maternal and fetal care.

Predicting long-term survival after de novo cardioverter-defibrillator implantation for primary prevention: A population based study

BackgroundImplantable cardioverter-defibrillators (ICDs) reduce the risk of sudden cardiac death in patients with left ventricular dysfunction. While short-term mortality benefit of ICD insertion has been established in landmark randomized controlled trials, little is known about the long-term outcomes of patients with ICDs in clinical practice. In this paper, we describe the long-term survival of patients following de novo ICD implantation for primary prevention in clinical practice and determine the factors which help predict survival after ICD implant. MethodsRetrospective population-based study of all patients receiving a de novo ICD for primary prevention in Ontario, Canada from 2007 to 2011 using the Ontario ICD Database housed within ICES. Simple random selection was used to split the population into a derivation and internal validation cohort in a ratio of 2:1. Cox proportional hazards regression was used to determine predictors of interest and predict 10-year survival, model performance was assessed using calibration and validation. ResultsIn the derivation cohort (n = 3399), mean age was 65.3 years (standard deviation [SD] = 11.0), 664 patients were female (19.5 %) and 2344 patients (69.0 %) had ischemic cardiomyopathy. Ten year survival was 45.7 % (95 % confidence interval [CI] 44.0 %–47.4 %). The final prediction model included age, sex, disease factors (ischemic vs nonischemic cardiomyopathy, left ventricular ejection fraction) and patient factors (symptoms, comorbidities), and biomarkers at the time of ICD assessment. This model had good discrimination and calibration in derivation (0.79, 95 % CI 0.77, 0.81) and validation samples (0.78, 95 % CI 0.76, 0.79). ConclusionsA combination of demographic and clinical factors determined at baseline can be used to predict 10-year survival in patients with implantable cardioverter-defibrillators with good accuracy. Our findings help to identify individuals at risk of long-term mortality and may be useful in targeting future prevention strategies to enhance longevity in this high-risk population.

Plasmodium infections and associated risk factors among parturients in Jawi district, northwest Ethiopia: a cross-sectional study

BackgroundPregnant women have an increased risk of Plasmodium infections and disease. Malaria in pregnancy is a major public health problem in endemic areas. Assessment of the burden and risk factors of malaria in pregnancy across different malaria transmission settings is required to guide control strategies and for malaria elimination. Thus, the current study is generating such evidence from parturient women in northwest Ethiopia.MethodsA cross-sectional study was conducted among 526 pregnant women admitted to the delivery rooms of selected health facilities in Jawi district, northwest Ethiopia, between November 2021 and July 2022. Data on the socio-demographic, clinical, obstetric, and malaria prevention practices of pregnant women were collected using interviewer-administered questionnaires and from women’s treatment cards. Malaria was diagnosed by light microscopy, rapid diagnostic test, and multiplex real-time polymerase chain reaction. Risk factors for malaria were evaluated using bivariable and multivariable logistic regression models. A P-value of < 0.05 was considered statistically significant.ResultsAmong the examined parturient women, 14.3% (95% CI 11.4–17.5%) had Plasmodium infections. The prevalence of peripheral, placental, and congenital malaria was 12.2% (95% CI 9.5–15.3%), 10.9% (95% CI 8.2–14.1%), and 3.7% (95% CI 2.3–6.1%), respectively. About 90.6% of peripheral and 92% of placental Plasmodium infections were asymptomatic. Plasmodium infection at parturiency was independently predicted by maternal illiteracy (AOR = 2.03, 95% CI 1.11–3.74), primigravidity (AOR = 1.88, 95% CI 1.01–3.49), lack of antenatal care follow-up (AOR = 2.28, 95% CI 1.04–5.03), and history of symptomatic malaria during pregnancy (AOR = 4.2, 95% CI 2.32–7.59). Moreover, the blood group O phenotype was significantly associated with placental malaria among the primiparae.ConclusionsOverall, asymptomatic Plasmodium infections were prevalent among parturients in northwest Ethiopia. Maternal illiteracy, primigravidity, lack of antenatal care follow-up, and history of symptomatic malaria during pregnancy were the risk factors for malaria during parturiency. Thus, promotion of a healthy pregnancy through ANC follow-up, strengthening malaria prevention and control practices, and screening of malaria in asymptomatic pregnant women are suggested to reduce its burden in pregnancy.

Impact of the stepwise approach to cardiovascular disease prevention in patients with established ASCVD from the 2021 ESC Prevention Guideline

Abstract Background The European Society of Cardiology (ESC) 2021 Guidelines on Cardiovascular Disease Prevention in Clinical Practice advocate a stepwise approach for the treatment of cardiovascular (CV) risk factors to reduce CV-risk in patients with established atherosclerotic cardiovascular disease (ASCVD). The aim of this study was to evaluate CV-risk reduction and residual risk for recurrent CV-events based on stepwise risk factor management. Methods In patients with established ASCVD in the UCC-SMART (n = 8,997) and European parts of the REACH registry (n = 18,364) receiving usual care, 10-year risk of recurrent major CV-events was calculated using the SMART2 risk score. The effect of guideline recommended step 1 and 2 treatment options on this risk was modelled using best available evidence from meta-analyses and trials. Step 1 treatment recommendations were smoking cessation, use an antithrombotic drug, LDL cholesterol &amp;lt;1.8 mmol/L, systolic blood pressure (SBP) &amp;lt;140 to 130 mmHg, and in people with type 2 diabetes mellitus a GLP1-receptor agonist/SGLT2-inhibitor. Step 2 treatment recommendations studied were LDL cholesterol &amp;lt;1.4 mmol/L, SBP &amp;lt;130 mmHg, dual pathway inhibition, colchicine, eicosapentaenoic acid (EPA), and in people with type 2 diabetes mellitus a GLP1-receptor agonist/SGLT2-inhibitor in people with type 2 diabetes. Two scenarios were evaluated: one with perfect attainment (ideal) and one with empiric attainment rates (realistic). Results The baseline median 10-year residual CV-risk was 26% [14-41%] overall, and 20%, 27%, and 54% in the low, moderate, and pooled high and very high European risk regions, respectively. Baseline risk was lowest in patients with only coronary artery disease and highest in patients with polyvascular disease or comorbid diabetes mellitus. In the ideal scenario, CV-risk was reduced to 14% [9-22%] overall and, 11%, 15%, and 29% following step 1 and 6% [4-10], 5%, 9%, and 12% following step 2. In the realistic scenario, CV-risk was reduced to 24% [16-36%], 20%, 24, and 47% following step 1 and 10% [7-16%], 9%, 9%, and 19% following step 2. In the ideal scenario, 43%, 22% and 4% achieved a residual risk of &amp;lt;10% following step 1 and 87%, 83% and 38% following step 2 in each respective risk region. In the realistic scenario this was 7%, 1%, and 0% after step 1 and 59%, 56%, and 13% after step 2 (Figure shows the realistic scenario for the low risk region &amp; moderate risk region). Conclusion Despite the current standard of care, patients with established ASCVD remain at high residual CV-risk across all European risk regions. Step 1 treatment targets may lower this risk substantially, but only if attainment rates are higher than empirically achieved. Intensified Step 2 treatment options result in marked further reduction of residual CV-risk and should be encouraged to be considered in all patients with established ASCVD.Realistic scenario low risk regionRealistic scenario moderate risk region
