Use of Lipoprotein(a) in clinical practice: A biomarker whose time has come. A scientific statement from the National Lipid Association

Lipoprotein(a) [Lp(a)] is a well-recognized, independent risk factor for atherosclerotic cardiovascular disease, with elevated levels estimated to be prevalent in 20% of the population. Observational and genetic evidence strongly support a causal relationship between high plasma concentrations of Lp(a) and increased risk of atherosclerotic cardiovascular disease-related events, such as myocardial infarction and stroke, and valvular aortic stenosis. In this scientific statement, we review an array of evidence-based considerations for testing of Lp(a) in clinical practice and the utilization of Lp(a) levels to inform treatment strategies in primary and secondary prevention.

Influence of slow light effect on trapping force in optical tweezers

We investigate the optical trapping of polystyrene microspheres in optical tweezers. The transverse capture gradient forces of polystyrene microspheres with different numerical aperture are theoretically and experimentally evaluated by the power spectral density roll-off method. It is found that the trapping force of the experimental measurement is much stronger than that of the theoretical results. The discordance is attributed to the slow light effect near the focus, which has been found in recent years [Science347, 857 (2015)10.1126/science.aaa3035; Opt. Express18, 10822 (2010)10.1364/OE.18.010822; Opt. Commun.332, 164 (2014)10.1016/j.optcom.2014.06.057]. The modified trapping force of the theoretical results by considering the slow light effect near the focus is well consistent with that of the experimental results.

Mutant clones in normal epithelium outcompete and eliminate emerging tumours

Human epithelial tissues accumulate cancer-driver mutations with age1-9, yet tumour formation remains rare. The positive selection of these mutations suggests that they alter the behaviour and fitness of proliferating cells10-12. Thus, normal adult tissues become a patchwork of mutant clones competing for space and survival, with the fittest clones expanding by eliminating their less competitive neighbours11-14. However, little is known about how such dynamic competition in normal epithelia influences early tumorigenesis. Here we show that the majority of newly formed oesophageal tumours are eliminated through competition with mutant clones in the adjacent normal epithelium. We followed the fate of nascent, microscopic, pre-malignant tumours in a mouse model of oesophageal carcinogenesis and found that most were rapidly lost with no indication of tumour cell death, decreased proliferation or an anti-tumour immune response. However, deep sequencing of ten-day-old and one-year-old tumours showed evidence of selection on the surviving neoplasms. Induction of highly competitive clones in transgenic mice increased early tumour removal, whereas pharmacological inhibition of clonal competition reduced tumour loss. These results support a model in which survival of early neoplasms depends on their competitive fitness relative to that of mutant clones in the surrounding normal tissue. Mutant clones in normal epithelium have an unexpected anti-tumorigenic role in purging early tumours through cell competition, thereby preserving tissue integrity.

Greater than expected reduction in low-density lipoprotein-cholesterol (LDL-C) with bempedoic acid in a patient with heterozygous familial hypercholesterolemia (HeFH)

Bempedoic acid is an adenosine triphosphate-citrate lyase (ACL) inhibitor that reduces levels of low-density lipoprotein-cholesterol (LDL-C) in the plasma by inhibition of cholesterol synthesis in hepatic cells, which leads to up-regulation of hepatic LDL receptors. Bempedoic acid is approved as an adjunct to diet and maximally tolerated statin therapy for the treatment of adults with heterozygous familial hypercholesterolemia (HeFH) who require additional lowering of LDL-C. In this case study, we describe a patient with HeFH who had a prior excellent response to statin but unable to take the same, and a less than expected response to PCSK9i, in whom initiation of bempedoic acid led to a substantial reduction of LDL-C. Our findings suggest that patients who are quite responsive to statins may also be quite responsive to bempedoic acid, a medication that works in the same biochemical pathway as HMG-CoA reductase inhibitors. Additionally, this medication may be particularly effective at lowering LDL-C among individuals not on background statin therapy.

A Comparison of Ezetimibe and Evolocumab for Atherogenic Lipid Reduction in Four Patient Populations: A Pooled Efficacy and Safety Analysis of Three Phase 3 Studies

INTRODUCTION

Clinicians, payers, guideline committees, and policymakers support the use of high-intensity statins in patients at high risk for complications of cardiovascular disease (CVD). Guidelines and recommendations provide guidance on next steps for patients with inadequate low-density lipoprotein cholesterol (LDL-C) control on maximally tolerated statin or for those who are statin-intolerant. Ezetimibe and evolocumab improve CV outcomes when added to statins in high-CV-risk populations. The aim of the study was to compare evolocumab and ezetimibe for lipid-lowering efficacy and safety.

METHODS

We summarized data from 1427 patients from three phase 3 evolocumab studies comparing double-blinded evolocumab vs. ezetimibe. These studies evaluated four distinct populations: those free of CVD receiving each agent as monotherapy, patients with CVD receiving add-on therapy to low- or high-intensity statin, and statin-intolerant patients. Lipid efficacy and safety were reported at week 12.

RESULTS

Across the studies, evolocumab reduced LDL-C by a mean 55-61% from baseline to week 12; ezetimibe lowered LDL-C by 18-20% from baseline (mean difference = 38-43% favoring evolocumab; p < 0.0001). This corresponded to absolute reductions in LDL-C of 60-104 mg/dL with evolocumab vs. 17-35 mg/dL with ezetimibe. Evolocumab also significantly improved other lipids and led to a higher percentage of patients achieving LDL-C goals vs. ezetimibe. Adverse events and discontinuation rates (oral and parenteral therapy) were balanced across groups, suggesting good tolerance and acceptance of both treatments.

CONCLUSIONS

Evolocumab outperformed ezetimibe in efficacy and lipid goal attainment. Both products demonstrated good safety/tolerability. These data may help guide access decisions for high-risk patients with inadequate treatment response or intolerance to statin therapy.

Lipoprotein(a) levels and risk of cardiovascular disease events in individuals with diabetes mellitus or prediabetes: The Atherosclerosis Risk in Communities study

BACKGROUND AND AIMS

Diabetes increases risk for atherosclerotic cardiovascular disease (ASCVD). Current guidelines do not recommend measuring lipoprotein(a), another ASCVD risk factor, in these individuals. We examined the association of lipoprotein(a) levels with incident ASCVD events in persons with and without diabetes or prediabetes.

METHODS

Lipoprotein(a) and other ASCVD risk factors were measured at baseline (1996-1998) in the biracial Atherosclerosis Risk in Communities study; participants without prevalent ASCVD (coronary heart disease or stroke) were monitored ∼15 years for incident ASCVD events.

RESULTS

Of 9871 eligible participants (mean age 63 years; 5816 women; 2155 African Americans), 1543 had diabetes and 3615 had prediabetes. Cumulative ASCVD incidence rates (event/1000-person years) were higher in participants with diabetes (26%) or prediabetes (13%) than in nondiabetic individuals (10%, p < 0.001). When comparing highest to lowest lipoprotein(a) categories (≥50 mg/dL vs. ≤10 mg/dL), increasing lipoprotein(a) levels were significantly associated with increasing incident ASCVD events in Caucasian participants with prediabetes (hazard ratio [HR] = 1.35; 95% confidence interval [CI] 1.07-1.69); p = 0.03) and diabetes (HR = 1.42; 95% CI 1.10-1.84; p < 0.01), but not those with normal fasting blood glucose. Adding lipoprotein(a) to Pooled Cohort Equation variables improved risk prediction in persons with diabetes (Δ in area under the receiver operating characteristic curve [AUC] 0.0087, net reclassification index [NRI] 0.1761) and prediabetes (ΔAUC 0.0025, NRI 0.0938).

CONCLUSIONS

In this biracial cohort, elevated lipoprotein(a) levels in Caucasian individuals with diabetes or prediabetes were associated with further increased ASCVD risk. Adding lipoprotein(a) to traditional risk factors improved ASCVD risk prediction.

Alirocumab safety in people with and without diabetes mellitus: pooled data from 14 ODYSSEY trials

AIM

To evaluate the safety of the proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitor alirocumab according to diabetes mellitus status.

METHODS

Safety data from 14 trials (8-104-week durations) were analysed by treatment (alirocumab or placebo/ezetimibe control) and diabetes status (yes/no, defined by medical history). Adverse event data were assessed using descriptive statistics and Cox models.

RESULTS

Of the 5234 trial participants, 1554 (29.7%) had diabetes. Overall, treatment-emergent adverse events were similar in the alirocumab and control groups, except for more frequent local injection site reactions with alirocumab. Fewer people with diabetes experienced local injection site reactions [alirocumab, 3.5%, control, 2.9%; hazard ratio 1.24 (95% CI 0.68-2.25)] than those without diabetes [alirocumab, 7.5%; control, 4.9%; hazard ratio 1.51 (95% CI 1.13-2.01)]. Those with diabetes reported a greater number of serious adverse events (alirocumab, 19.4%; control, 19.7%) than those without diabetes (alirocumab, 14.5%; control, 13.5%). In people with diabetes, major adverse cardiac events occurred in 2.7% of alirocumab-treated people [control, 3.3%; hazard ratio 0.74 (95% CI 0.41-1.35)]; in those without diabetes, 1.8% of alirocumab-treated people had major adverse cardiac events [control, 1.7%; hazard ratio 0.95 (95% CI 0.56-1.62)]. Overall, no increase in HbA1c or fasting plasma glucose vs control treatment groups was observed, regardless of diabetes status.

CONCLUSION

This pooled analysis across 14 trials demonstrated similar safety for alirocumab vs control treatment, irrespective of diabetes status, except for more frequent local injection site reactions with alirocumab. People with diabetes reported fewer local injection site reactions than those without diabetes.

New approaches to pharmacosurveillance for monitoring prescription frequency, diversity, and co-prescription in a large sentinel network of companion animal veterinary practices in the United Kingdom, 2014-2016

Pharmaceutical agents (PAs) are commonly prescribed in companion animal practice in the United Kingdom. However, little is known about PA prescription on a population-level, particularly with respect to PAs authorised for human use alone prescribed via the veterinary cascade; this raises important questions regarding the efficacy and safety of PAs prescribed to companion animals. This study explored new approaches for describing PA prescription, diversity and co-prescription in dogs, cats and rabbits utilising electronic health records (EHRs) from a sentinel network of 457 companion animal-treating veterinary sites throughout the UK over a 2-year period (2014-2016). A novel text mining-based identification and classification methodology was utilised to semi-automatically map practitioner-defined product descriptions recorded in 918,333 EHRs from 413,870 dogs encompassing 1,242,270 prescriptions; 352,730 EHRs from 200,541 cats encompassing 491,554 prescriptions, and 22,526 EHRS from 13,398 rabbits encompassing 18,490 prescriptions respectively. PA prescription as a percentage of booked consultations was 65.4% (95% confidence interval, CI, 64.6-66.3) in dogs; in cats it was 69.1% (95% CI, 67.9-70.2) and in rabbits, 56.3% (95% CI, 54.7-57.8). Vaccines were the most commonly prescribed PAs in all three species, with antibiotics, antimycotics, and parasiticides also commonly prescribed. PA prescription utilising products authorised for human use only (hence, 'human-authorised') comprised 5.1% (95% CI, 4.7-5.5) of total canine prescription events; in cats it was 2.8% (95% CI, 2.6-3.0), and in rabbits, 7.8% (95% CI, 6.5-9.0). The most commonly prescribed human-authorised PA in dogs was metronidazole (antibiotic); in cats and rabbits it was ranitidine (H2 histamine receptor antagonist). Using a new approach utilising the Simpson's Diversity Index (an ecological measure of relative animal, plant etc. species abundance), we identified differences in prescription based on presenting complaint and species, with rabbits generally exposed to a less diverse range of PAs than dogs or cats, potentially reflecting the paucity of authorised PAs for use in rabbits. Finally, through a novel application of network analysis, we demonstrated the existence of three major co-prescription groups (preventive health; treatment of disease, and euthanasia); a trend commonly observed in practice. This study represents the first time PA prescription has been described across all pharmaceutical families in a large population of companion animals, encompassing PAs authorised for both veterinary and human-only use. These data form a baseline against which future studies could be compared, and provides some useful tools for understanding PA comparative efficacy and risks when prescribed in the varied setting of clinical practice.

Case reports of proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibition nonresponse

Proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors, a novel class of monoclonal antibodies, reduces low-density lipoprotein cholesterol levels and improves cardiovascular outcomes. Given the short time frame, these agents have been available for use; reports of nonresponse to the PCSK9 inhibitor therapy are scarce in literature. We describe 2 cases with substantially lesser than expected low-density lipoprotein cholesterol lowering on PCSK9 therapy. Nonresponse to PCSK9 inhibition was attributed to autosomal recessive hypercholesterolemia (secondary to low-density lipoprotein receptor adaptor protein 1 mutation) and plasmapheresis after PCSK9 inhibitor drug injections. Additional PCSK9 inhibitor nonresponders are likely to emerge as the use of these agents increases overtime.

Cardiovascular Disease Prevention: Training Opportunities, the Challenges, and Future Directions

PURPOSE

Cardiovascular diseases (CVDs) are a leading cause of morbidity and mortality worldwide, necessitating major efforts in prevention. This review summarizes the currently available training opportunities in CVD prevention for fellows-in-training (FITs) and residents. We also highlight the challenges and future directions for CVD prevention as a field and propose a structure for an inclusive CVD prevention training program.

RECENT FINDINGS

At present, there is a lack of centralized training resources for FITs and residents interested in pursuing a career in CVD prevention. Training in CVD prevention is not an accredited subspecialty fellowship by the American Council of Graduate Medical Education (ACGME). Although there are several independent training programs under the broad umbrella of CVD prevention focusing on different aspects of prevention, there is no unified curriculum or training. More collaborative efforts are needed to identify CVD prevention as an ACGME-accredited subspecialty fellowship. Providing more resources can encourage and produce more leaders in this essential field.

Optical trapping and optical force positioning of two-dimensional materials

In recent years, considerable effort has been devoted to the synthesis and characterization of two-dimensional materials. Liquid phase exfoliation (LPE) represents a simple, large-scale method to exfoliate layered materials down to mono- and few-layer flakes. In this context, the contactless trapping, characterization, and manipulation of individual nanosheets hold perspectives for increased accuracy in flake metrology and the assembly of novel functional materials. Here, we use optical forces for high-resolution structural characterization and precise mechanical positioning of nanosheets of hexagonal boron nitride, molybdenum disulfide, and tungsten disulfide obtained by LPE. Weakly optically absorbing nanosheets of boron nitride are trapped in optical tweezers. The analysis of the thermal fluctuations allows a direct measurement of optical forces and the mean flake size in a liquid environment. Measured optical trapping constants are compared with T-matrix light scattering calculations to show a quadratic size scaling for small size, as expected for a bidimensional system. In contrast, strongly absorbing nanosheets of molybdenum disulfide and tungsten disulfide are not stably trapped due to the dominance of radiation pressure over the optical trapping force. Thus, optical forces are used to pattern a substrate by selectively depositing nanosheets in short times (minutes) and without any preparation of the surface. This study will be useful for improving ink-jet printing and for a better engineering of optoelectronic devices based on two-dimensional materials.

Association of low-density lipoprotein pattern with mortality after myocardial infarction: Insights from the TRIUMPH study

BACKGROUND

Studies of incident coronary heart disease risk within low-density lipoprotein (LDL) subclass (small, dense vs large, buoyant) have shown mixed results. No prospective cohort study has examined the association of small, dense, or large, buoyant LDL with mortality after myocardial infarction (MI).

OBJECTIVE

The objective of the study was to examine association of LDL pattern after MI and death.

METHODS

In 2476 patients hospitalized for MI, LDL pattern (A [large, buoyant], A/B [mixed], and B [small, dense]) was established by ultracentrifugation using Vertical Auto Profile. Using time-to-event analysis, we examined the association with 5-year mortality within LDL patterns, after adjusting for important patient and treatment characteristics. We additionally adjusted for LDL cholesterol (LDL-C) and triglyceride levels and used directly measured LDL-C and non-high-density lipoprotein cholesterol as exposures.

RESULTS

Patterns A, A/B, and B were present in 39%, 28%, and 33% of patients, respectively, with incident rates (per 1000 patient-years) of 50, 34, and 24 for all-cause and 24, 19, and 10 for CV mortality. The hazard ratios (95% confidence interval) with LDL patterns A/B and B compared with pattern A were 0.77 (0.61, 0.99) and 0.67 (0.51, 0.88) for all-cause, 0.94 (0.67, 1.33) and 0.69 (0.46, 1.03) for cardiovascular, and 0.64 (0.45, 0.91) and 0.65 (0.45, 0.93) for noncardiovascular mortalities, respectively. Results were similar when further adjusted for LDL-C and triglycerides, or with LDL-C and non-high-density lipoprotein cholesterol as exposures.

CONCLUSION

Compared with LDL pattern A, pattern B was significantly associated with reduced all-cause and non-CV mortalities with a trend for lower CV mortality after MI, independent of LDL-C and triglycerides.

Developing Optimized Treatment Plans for Patients with Dyslipidemia in the Era of Proprotein Convertase Subtilisin/Kexin Type 9 Inhibitor Therapeutics

This educational content was derived from a live satellite symposium at the American College of Physicians Internal Medicine Meeting 2017 in San Diego, California (online at http://courses.elseviercme.com/acp/702e). This activity will focus on optimized treatment plans for patients with dyslipidemia in the era of proprotein convertase subtilisin/kexin type 9 inhibitor therapeutics. Low-density lipoprotein cholesterol has been identified as an important therapeutic target to prevent the progression of atherosclerotic disease; however, only 1 of every 3 adults with high low-density lipoprotein cholesterol has the condition under control. Expert faculty on this panel will discuss the science of proprotein convertase subtilisin/kexin type 9 inhibitors and aid physicians in the best practices to achieve low-density lipoprotein cholesterol target in their patients.

Patterns of antimicrobial agent prescription in a sentinel population of canine and feline veterinary practices in the United Kingdom

•

Antimicrobial agent prescription was monitored in a large UK population of cats and dogs over a 2 year period (2014–2016).

•

Systemic antimicrobial agents were prescribed more frequently to cats; topical prescription was more frequent in dogs.

•

A temporal reduction (2014–2016) in antimicrobial agent prescription was observed in both cats and dogs in this population.

•

Premises which prescribed antimicrobial agents commonly to cats generally also prescribed commonly to dogs.

•

The most frequently prescribed antibiotics were cefovecin in cats and clavulanic acid potentiated amoxicillin in dogs.

Antimicrobial resistance is an increasingly important global health threat and the use of antimicrobial agents is a key risk factor in its development. This study describes antimicrobial agent prescription (AAP) patterns over a 2 year period using electronic health records (EHRs) from booked consultations in a network of 457 sentinel veterinary premises in the United Kingdom. A semi-automated classification methodology was used to map practitioner defined product codes in 918,333 EHRs from 413,870 dogs and 352,730 EHRs from 200,541 cats, including 289,789 AAPs. AAP as a proportion of total booked consultations was more frequent in dogs (18.8%, 95% confidence interval, CI, 18.2–19.4) than cats (17.5%, 95% CI 16.9–18.1). Prescription of topical antimicrobial agents was more frequent in dogs (7.4%, 95% CI 7.2–7.7) than cats (3.2%, 95% CI 3.1–3.3), whilst prescription of systemic antimicrobial agents was more frequent in cats (14.8%, 95% CI 14.2–15.4) than dogs (12.2%, 95% CI 11.7–12.7). A decreasing temporal pattern was identified for prescription of systemic antimicrobial agents in dogs and cats. Premises which prescribed antimicrobial agents frequently for dogs also prescribed frequently for cats. AAP was most frequent during pruritus consultations in dogs and trauma consultations in cats. Clavulanic acid potentiated amoxicillin was the most frequently prescribed antimicrobial agent in dogs (28.6% of prescriptions, 95% CI 27.4–29.8), whereas cefovecin, a third generation cephalosporin, was the most frequently prescribed antimicrobial agent in cats (36.2%, 95% CI 33.9–38.5). This study demonstrated patterns in AAP over time and for different conditions in a population of companion animals in the United Kingdom.

Synthesis maps: visual knowledge translation for the CanIMPACT clinical system and patient cancer journeys

Salient findings and interpretations from the canimpact clinical cancer research study are visually represented in two synthesis maps for the purpose of communicating an integrated presentation of the study to clinical cancer researchers and policymakers. Synthesis maps integrate evidence and expertise into a visual narrative for knowledge translation and communication. A clinical system synthesis map represents the current Canadian primary care and cancer practice systems, proposed as a visual knowledge translation from the mixed-methods canimpact study to inform Canadian clinical research, policy, and practice discourses. Two synthesis maps, drawn together from multiple canimpact investigations and sources, were required to articulate critical differences between the clinical system and patient perspectives. The synthesis map of Canada-wide clinical cancer systems illustrates the relationships between primary care and the full cancer continuum. A patient-centred map was developed to represent the cancer (and primary care) journeys as experienced by breast and colorectal cancer patients.

Safety of Alirocumab (A PCSK9 Monoclonal Antibody) from 14 Randomized Trials

Previous individual trials of alirocumab (a PCSK9 monoclonal antibody) showed significant low-density lipoprotein cholesterol reductions with overall treatment-emergent adverse event (TEAE) rates comparable with controls. This analysis evaluated safety data from 14 trials (4 phase 2 and 10 phase 3, 8 to 104 weeks; n = 5,234), in 2 pools according to control (placebo/ezetimibe). Overall, 3,340 patients received alirocumab (4,029 patient-years' exposure), 1,276 received placebo, and 618 received ezetimibe. Incidence of deaths, serious TEAEs, discontinuations because of TEAEs, and overall TEAEs were similar between alirocumab and control groups. Alirocumab was associated with a higher incidence of local injection site reactions (7.4% vs 5.3% with placebo; 3.1% vs 2.3% with ezetimibe), pruritus (1.3% vs 0.4% placebo; 0.9% vs 0.5% ezetimibe), and upper respiratory tract infection signs and symptoms (2.1% vs 1.1% placebo; 1.3% vs 0.8% ezetimibe). Incidence of musculoskeletal, neurologic, neurocognitive, ophthalmologic, hepatic events, and TEAEs related to diabetes/diabetes complications was similar between alirocumab and control groups. In a prespecified analysis of phase 3 studies, adjudicated major adverse cardiovascular events (coronary heart disease death, nonfatal myocardial infarction, ischemic stroke, and unstable angina requiring hospitalization) occurred in 1.8% alirocumab versus 2.6% placebo patients (hazard ratio 0.69, 95% confidence interval 0.43 to 1.11) and 2.8% alirocumab versus 1.5% ezetimibe patients (hazard ratio 1.4, 95% confidence interval 0.65 to 3.02). In conclusion, pooled safety data from 14 trials demonstrate that alirocumab is generally well tolerated with a favorable safety profile.

Optical manipulation using highly focused alternate radially and azimuthally polarized beams modulated by a devil's lens

We propose and demonstrate a novel high numerical aperture (NA) focusing system composed of an annular beam with alternate radially and azimuthally polarized rings, focused by a devil's lens (DL), and further investigate its radiation forces acting upon a Rayleigh particle both analytically and numerically. Strongly focused cylindrical vector beams produce either dark-centered or peak-centered intensity distributions depending on the state of polarization, whereas the DL produces a series of foci along the propagation direction. We exploit these focusing properties and show that by selecting an appropriate truncation parameter in front of the focusing lens, the proposed optical focusing system can selectively trap and manipulate dielectric micro-particles with low or high refractive indices by simply adjusting the radius of the pupil or the beam. Finally, the stability conditions for effectively trapping and manipulating Rayleigh particles are analyzed. The results obtained in this work are of interest in possible applications in optical confinement and manipulation, sorting micro-particles, and making use of a DL.
