Abstract Aims To validate the reported increased atherosclerotic cardiovascular disease (ASCVD) risk associated with very high lipoprotein(a) [Lp(a)] and to investigate the impact of routine Lp(a) assessment on risk reclassification. Methods and results We performed a cross-sectional case-control study in the Amsterdam UMC, a tertiary hospital in The Netherlands. All patients in whom a lipid blood test was ordered between October 2018 and October 2019 were included. Individuals with Lp(a) >99th percentile were age and sex matched to individuals with Lp(a) ≤20th percentile. We computed odds ratios (ORs) for myocardial infarction (MI) and ASCVD using multivariable logistic regression adjusted for age, sex, and systolic blood pressure. Furthermore, we assessed the additive value of Lp(a) to established ASCVD risk algorithms. Lipoprotein(a) levels were determined in 12 437 individuals, out of whom 119 cases [Lp(a) >99th percentile; >387.8 nmol/L] and 119 matched controls [Lp(a) ≤20th percentile; ≤7 nmol/L] were included. Mean age was 58 ± 15 years, 56.7% were female, and 30.7% had a history of ASCVD. Individuals with Lp(a) levels >99th percentile had an OR of 2.64 for ASCVD [95% confidence interval (CI) 1.45–4.89] and 3.39 for MI (95% CI 1.56–7.94). Addition of Lp(a) to ASCVD risk algorithms led to 31% and 63% being reclassified into a higher risk category for Systematic Coronary Risk Evaluation (SCORE) and Second Manifestations of ARTerial disease (SMART), respectively. Conclusion The prevalence of ASCVD is nearly three-fold higher in adults with Lp(a) >99th percentile compared with matched subjects with Lp(a) ≤20th percentile. In individuals with very high Lp(a), addition of Lp(a) resulted in one-third of patients being reclassified in primary prevention, and over half being reclassified in secondary prevention.

The use of a highly-effective treatment for multiple sclerosis (MS) is associated with a severe risk of developing complications, such as progressive multifocal leukoencephalopathy (PML) caused by the John Cunningham virus (JCV). The aim of this study was to evaluate the correlation between anti-JCV Ab seroprevalence, anti-JCV AI, demographic and clinical factors as well as the type of therapy used in the Polish MS population. This is a multicentre, prospective and cross-sectional study involving 1405 MS patients. The seroprevalence of anti-JCV Ab and anti-JCV AI levels as well as AI categories were analysed with the use of a second-generation two-step ELISA test (STRATIFY JCV DxSelect). The overall prevalence of anti-JCV Ab was 65.8%. It was shown that seroprevalence increases with the patient’s age. The seroprevalence was significantly associated with the treatment type, and the highest values (76%) were obtained from immunosuppressant-treated patients. Overall, 63.3% of seropositive patients had an antibody index (AI) level of >1.5. In the seropositive patient group, the mean AI level amounted to 2.09. Similarly to the seroprevalence, AI levels correlated with the patient’s age; AI level for patients above 40 years old and from subsequent age quintiles plateaued, amounting to at least 1.55. Patients treated with immunosuppressants and immunomodulatory drugs obtained the highest (1.67) and lowest (1.35) AI levels, respectively. Of the immunosuppressants used, the highest mean AI levels were observed in mitoxantrone and cladribine groups, amounting to 1.75 and 1.69, respectively. In patients treated with immunomodulatory drugs, the lowest AI levels were observed in the dimethyl fumarate (DMF) group (1.11). The seroprevalence rate in the Polish MS population is one of the highest in Europe. The majority of seropositive patients had an anti-JCV Ab level qualifying them for a high-risk category. The highest mean AI levels are observed in patients receiving immunosuppressants, especially mitoxantrone and cladribine. Patients receiving immunomodulatory drugs have lower AI levels compared to treatment-naïve subjects, especially when treated with DMF. Further studies, especially longitudinal studies, are required to determine the impact of MS drugs on the seroprevalence of anti-JCV Ab and AI levels.

Introduction: Lipoprotein (a) (Lp(a)) and inflammation, as represented by elevated high-sensitivity C-reactive protein (hsCRP) concentration, are both considered as risk-enhancers in the 2018 AHA/ACC Cholesterol guidelines. However, little is known as to whether the association of Lp(a) with atherosclerotic cardiovascular disease (ASCVD) risk is modified by inflammation. Objective: We assessed whether hsCRP modifies the association of Lp(a) with ASCVD risk. Methods: MESA participants with baseline hsCRP and Lp(a) levels were included. Incident ASCVD events were ascertained from baseline through 2017. Time to incident ASCVD was analyzed using Kaplan Meir curves. Cox proportional hazards models were used to assess the association between Lp(a), hsCRP, and time to ASCVD events adjusting for covariates. Results: The study included 4,654 participants with mean age of 62 and 52.5% females (1,702 Caucasians, 557 Chinese Americans, 1,336 African Americans and 1,059 Hispanics). With a mean 13.6-year follow-up, 676 ASCVD events occurred among 4,609 participants (Figure 1). In participants with hsCRP <2mg/L, the association of Lp(a) (per 1 Log unit increase) and risk for ASCVD as represented by hazard ratio (HR) and 95%CI was 1.01 (0.79, 1.28). In subjects with hsCRP ≥2mg/L, the risk increased to 1.26 (1.01, 1.58). When compared to the reference group with Lp(a) <50mg/dL and hsCRP <2mg/L, the risk for ASCVD in participants with Lp(a) ≥50mg/dL and hsCRP <2mg/L was 1.13 (0.85, 1.50) and in those with Lp(a) <50mg/dL and hsCRP ≥2mg/L was 1.09 (0.92, 1.31). The risk increased significantly to 1.62 (1.26, 2.07) in participants with Lp(a) ≥50mg/dL and hsCRP ≥2mg/L. Conclusions: Lp(a)-related ASCVD risk is modified by hsCRP levels. The findings of this analysis suggest that Lp(a) may serve as a risk enhancing factor in individuals with hsCRP level ≥2mg/L. Future studies are needed to determine whether Lp(a) is associated with risk of ASCVD in the absence of subclinical inflammation.

n-3 PUFA may exert favourable effects on several processes that may inhibit the atherosclerotic process. However, the role of n-3 PUFA in lowering the risk of atherosclerotic CVD (ASCVD) has been fiercely debated. In the present paper, we summarise the main findings from previous follow-up studies of intake and studies using adipose tissue as an objective biomarker to investigate exposure to n-3 PUFA in relation to ASCVD risk and discuss some perspectives for further research. The majority of previous studies investigating intake of marine- and plant-based n-3 PUFA have focused on CHD while other ASCVD such as ischaemic stroke and peripheral artery disease have been less studied. However, recent data from Danish Diet, Cancer and Health cohort suggest that marine n-3 PUFA may be inversely associated with risk of myocardial infarction, ischaemic stroke and peripheral arterial disease caused by atherosclerosis. The effect of the plant-derived n-3 PUFA α-linolenic acid on ASCVD is less clear and several gaps in the literature remain to be explored.

There is a scarcity of published research describing the impact of a pharmacist on the post-take ward round (PTWR) in addition to ward-based pharmacy services. The aim of this paper was to evaluate the impact of clinical pharmacists’ participation on the PTWR on the risk assessment scores of medication-related recommendations with and without a pharmacist. This includes medication-related recommendations occurring on the PTWR and those recommendations made by the ward-based pharmacist on the inpatient ward. A pre–post intervention study was undertaken that compared the impact of adding a pharmacist to the PTWR compared with ward-based pharmacist services alone. A panel reviewed the risk of not acting on medication recommendations that was made on the PTWR and those recorded by the ward-based pharmacist. The relationship between the risk scores and the number and proportion of recommendations that led to action were compared between study groups. There were more medication-related recommendations on the PTWR in the intervention group when a pharmacist was present. Proportionately fewer were in the ’very high and extreme’ risk category. Although there was no difference in the number of ward pharmacist recommendations between groups, there was a significantly higher proportion of ward pharmacist recommendations in the “very high and extreme” category in those patients who had been seen on a PTWR attended by a pharmacist than when a pharmacist was not present. There were a greater proportion of “low and medium” risk actionable medication recommendations actioned on the PTWR in the intervention group; and no difference in the risk scores in ward pharmacist recommendations actioned between groups. Overall, the proportion of recommendations that were actioned was higher for those made on the PTWR compared with the ward. The addition of a pharmacist to the PTWR resulted in an increase in low, medium, and high risk recommendations on the PTWR, more very high and extreme risk recommendations made by the ward-based pharmacist, plus an increased number of recommendations being actioned during the patients’ admission.

Objective.Because the addition of carotid ultrasound (US) into composite cardiovascular (CV) risk scores has been found effective for identifying patients with inflammatory arthritis and high CV risk, we aimed to determine whether its use would facilitate the reclassification of patients with psoriatic arthritis (PsA) into the very high Systematic Coronary Risk Evaluation (SCORE) risk category and whether this might be related to disease features.Methods.This was a cross-sectional study involving 206 patients who fulfilled ClASsification for Psoriatic ARthritis criteria for PsA, and 179 controls. We assessed lipid profile, SCORE, disease activity measurements, and the presence of carotid plaques and carotid intima-media thickness by ultrasonography. A multivariable regression analysis, adjusted for classic CV risk factors, was performed to evaluate whether the risk of reclassification could be explained by disease-related features and to assess the most parsimonious combination of risk reclassification predictors.Results.Forty-seven percent of patients were reclassified into a very high SCORE risk category after carotid US compared to 26% of controls (p < 0.001). Patients included in the low SCORE risk category were those who were more commonly reclassified (30% vs 14%, p = 0.002). The Disease Activity Index for PsA (DAPSA) score was associated with reclassification (β 1.10, 95% CI 1.02–1.19; p = 0.019) after adjusting for age and traditional CV risk factors. A model containing SCORE plus age, statin use, and DAPSA score yielded the highest discriminatory accuracy compared to the SCORE-alone model (area under the receiver-operating characteristic curve 0.863, 95% CI 0.789–0.936 vs 0.716, 95% CI 0.668–0.764; p < 0.001).Conclusion.Patients with PsA are more frequently reclassified into the very high SCORE risk category following carotid US assessment than controls. This was independently explained by the disease activity.

An Improved Ultrasonic B-scan/Doppler system has been developed for the noninvasive assessment of atherosclerotic arterial disease. Very high-resolution cross-sectional images of anatomic structures are produced by the 10-MHz B-scan subsystem. Instantaneous profiles of blood flow velocity as a function of position are produced by a bidirectional 16-channel pulsed-Doppler subsystem, operating at 5 MHz. Flow profiles are superimposed on the B-scan image, allowing simultaneous evaluation of anatomic structure and blood flow dynamics. Images of the carotid artery, thyroid gland, testicle, and eye are presented to demonstrate the diagnostic potential for imaging peripheral anatomy.

Abstract Background Early diagnosis and timely treatment for the patients with familial hypercholesterolemia (FH) can substantially lower the risk of atherosclerotic cardiovascular disease (ASCVD). In this sense, cascade screening could be one of the most useful options. However, few data exist regarding the impact of cascade screening for FH on the reduction of risk of ASCVD events. Objectives We aimed to evaluate the prognostic impact of cascade screening for FH. Methods We retrospectively investigated the health records of 1,050 patients with clinically diagnosed FH, including probands and their relatives who were cascade-screened. We used Cox models that were adjusted for established ASCVD risk factors to assess the association between cascade screening and major adverse cardiovascular events (MACE). The median period of follow-up was 12.3 years (interquartile range [IQR] = 9.1–17.5 years), and MACE included death from any causes or hospitalization due to ASCVD events. Results During the observation period, 246 participants experienced MACE. The mean age of patients identified through cascade screening was 18-years younger than that of the probands (38.7 yr vs. 57.0 yr, P&lt;0.001), with a lower proportion of ASCVD risk factors. Interestingly, patients identified through cascade screening under milder lipid-lowering therapies were at reduced risk for MACE (hazard ratio [HR] = 0.36; 95% CI = 0.22 to 0.60; P&lt;0.001) when compared with the probands, even after adjusting for those known risk factors. Conclusions The identification of patients with FH via cascade screening appeared to result in better prognoses.

Abstract Background In human immunodeficiency virus (HIV) treatment, tenofovir alafenamide (TAF) is associated with greater increases in all fasting cholesterol subgroups compared with tenofovir disoproxil fumarate (TDF). Because lipid abnormalities may contribute to cardiovascular morbidity and mortality, cardiovascular risk assessment is integral to routine HIV care. This post hoc study evaluates the impact of lipid changes on predicted atherosclerotic cardiovascular disease (ASCVD) risk and statin eligibility in treatment-naive adults living with HIV treated with TAF or TDF. Methods Participants (N = 1744) were randomized (1:1) to initiate TAF or TDF, each coformulated with elvitegravir/cobicistat/emtricitabine (studies GS-US-292-0104 and GS-US-292-0111). Eligibility for statin therapy and estimated 10-year ASCVD risk among adults aged 40–79 years treated with TAF or TDF for 96 weeks (W96) were analyzed based on American College of Cardiology/American Heart Association Pooled Cohort Equations. Categorical shifts in 10-year ASCVD risk from &lt;7.5% to ≥7.5% by W96 on TAF versus TDF were calculated. Results Participants initiating TAF versus TDF in the overall study population showed small but significant increases in median fasting lipid parameters at W96, including total cholesterol (191 vs 177 mg/dL; P &lt; .001), low-density lipoprotein ([LDL] 119 vs 112 mg/dL; P &lt; .001), and high-density lipoprotein ([HDL] 51 vs 48 mg/dL; P &lt; .001), respectively. At baseline, 18% and 23% on TAF versus TDF had a 10-year ASCVD risk score ≥7.5%, with mean risk scores low overall for TAF versus TDF at baseline (4.9% vs 5.4%; P = .35) and W96 (6.1% vs 6.2%; P = .04). Increases in ASCVD risk from baseline to W96 were driven by both increasing age and changes in total cholesterol (TC) and HDL cholesterol. At W96, TC/HDL ratios (median) were 3.7 for both groups (P = .69). There was no difference between shifts in categorical risk for TAF versus TDF (9% vs 5%; P = .19). Eligibility for high-intensity statin therapy were similar for TAF versus TDF groups (19% vs 21%; P = .47). Conclusions Lipid changes with TAF as part of coformulated regimens do not substantively affect CVD risk profiles compared with TDF.

ABSTRACT Objective: To describe and evaluate the pharmacotherapeutic follow-up by a clinical pharmacist in an intensive care unit. Methods: A descriptive and cross-sectional study carried out from August to October 2016. The data were collected through a form, and pharmacotherapeutic follow-up conducted by a clinical pharmacist at the respiratory intensive care unit of a tertiary hospital. The problems recorded in the prescriptions were quantified, classified and evaluated according to severity; the recommendations made by the pharmacist were analyzed considering the impact on pharmacotherapy. The medications involved in the problems were classified according to the Anatomical Therapeutic Chemical Classification System. Results: Forty-six patients were followed up and 192 pharmacotherapy-related problems were registered. The most prevalent problems were missing information on the prescription (33.16%), and those with minor severity (37.5%). Of the recommendations made to optimize pharmacotherapy, 92.7% were accepted, particularly those on inclusion of infusion time (16.67%), and dose appropriateness (13.02%), with greater impact on toxicity (53.6%). Antimicrobials, in general, for systemic use were drug class most often related to problems in pharmacotherapy (53%). Conclusion: Pharmacotherapeutic follow-up conducted by a pharmacist in a respiratory intensive care unit was able to detect problems in drug therapy and to make clinically relevant recommendations.

Abstract Introduction: Anxiety and depression are prevalent comorbidities in cancer patients. Although cancer treatment is funded by the Brazilian Unified Health System (SUS), economic burden is also borne by patients through out-of-pocket costs. Our study sought to evaluate the impact of out-of-pocket costs of cancer treatment on depression, anxiety and stress levels in cancer patients.Methods: Observational, cross-sectional and analytical study conducted in 2021. Patients undergoing chemotherapy were being treated at tertiary hospital affiliated with the SUS and enrolled in research protocols at research center. To evaluate out-of-pocket costs, we used a socioeconomic questionnaire to identify costs and time spent by patients. Primary outcomes were prevalence of depression and anxiety, as determined by the Hospital Anxiety and Depression Scale (HADS), and prevalence of stress, as determined using a stress thermometer.Results: 195 patients were included. Among included patients, 61% were female, and mean age was 57 years. Patients' median overall out-of-pocket costs was R$ 453.80 (US$ 78.92). Based on the HADS, 62.1% of patients had possible or probable depression/anxiety. There was no correlation between overall out-of-pocket spending and levels of depression/anxiety. However, when stratified by cost-time variables, there was a negative correlation between spending on telephones and HADS (rho = -0.140; P = 0.049) and positive correlations between spending on medications (rho = 0.140; P = 0.05) and time spent purchasing medications (rho = 0.157; P = 0.029) with HADS.Conclusion: Although overall spending was not directly correlated with mental health, specific costs impacted levels of anxiety, depression and stress.
