Rashid, R, Mir, SA, Kareem, O, Ali, T, Ara, R, Malik, A, Amin, F, Bader, GN
Taiwanese journal of obstetrics & gynecology. 2022;(1):40-50
Abstract
Polycystic ovary syndrome (PCOS), the most common endocrinopathy in women is characterized by polycystic ovaries, chronic anovulation and hyperandrogenism. The treatment in PCOS is mainly symptomatic and involves lifestyle interventions and medications such as Metformin, Oral contraceptives and Antiandrogens. However, the management of PCOS is challenging and current interventions are not able to deal with outcomes of this syndrome. This review encompasses latest pharmacotherapeutic and non-pharmacotherapeutic interventions currently in use to tackle various symptomatic contentions in PCOS. Our focus has been mainly on novel therapeutic modalities for treatment/management of PCOS, like use of newer insulin sensitizers viz., Inositols, Glucagon-like peptide-1(GLP-1) agonists, Dipeptidyl pepdidase-4 (DPP-4) inhibitors, and sodium-glucose transport protein 2 (SGLT2) inhibitors. Also, evidence suggesting the use of vitamin D, statins, and Letrozole as emerging therapies in PCOS have been summarized in this review. Additionally, novel cosmetic techniques like electrolysis, laser and use of topically applied eflornithine to tackle the most distressing feature of facial hirsutism associated with PCOS, non-pharmacological therapy like acupuncture and the role of herbal medicine in PCOS management have also been discussed.

Abstract
This review summarizes the pharmacology and clinical use of HMG-CoA reductase inhibitors, statins. LDL-Cholesterol lowering with statins reduces atherosclerotic cardiovascular risk by approx. one quater per year of treatment. The efficacy and safety of statins are demonstrated by randomized trials irrespective of the patient's age. The synthetic statins, rosuvastatin and atorvastatin, are superior with regard to LDL-C lowering, half-life and drug-interactions compared to the older statins such as simvastatin. Modern lipid lowering therapy uses individualized statin-based combination therapies.

Meta-Analysis Comparing the Effect of Combined Omega-3 + Statin Therapy Versus Statin Therapy Alone on Coronary Artery Plaques.
Fan, H, Zhou, J, Yuan, Z
The American journal of cardiology. 2021;:15-24
Abstract
Statin therapy plays an important role in stabilizing and regressing coronary artery plaques. Omega-3 supplements also have anti-inflammatory and antioxidant effects on coronary plaques. However, the effect of omega-3 supplementation on the basis of statin therapy on the stability and composition of plaques, is still unclear. We searched for randomized controlled trials published prior to November 2020 in the PubMed, Embase and Cochrane databases. Finally, eight studies using different imaging techniques to evaluate coronary atherosclerotic plaque, including optical coherence tomography (OCT), coronary CT angiography (cCTA) and intravascular ultrasound (IB-IVUS), met our inclusion criteria. We pooled data extracted from the included studies using the standardized mean difference (SMD) or mean difference (MD) of the random effects model. Compared with statin treatment alone, the combined treatment further delayed the progression of total plaque volume [SMD -0.36, 95% confidence interval (CI) -0.64 to -0.08, p = 0.01] and fiber content (SMD -0.40, 95% CI -0.68 to -0.13, p = 0.004). The plasma high-sensitivity C-reactive protein (hs-CRP) level of patients in the combination treatment group was significantly lower than that of the patients in the statin treatment group alone (SMD -0.30, 95% CI -0.59 to -0.01, p = 0.04). In addition, the combined use of omega-3 further increases the fibrous cap thickness (FCT) of the plaque with an MD of 29.45 μm. There were no significant differences in plasma high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), or lipid content in plaques between the two groups. Omega-3 combined with statins is superior to the statin treatment group in stabilizing and promoting coronary plaque regression and may help to further reduce the occurrence of cardiovascular events.

Beneficial Effect of Statin Therapy on Arterial Stiffness.
Alidadi, M, Montecucco, F, Jamialahmadi, T, Al-Rasadi, K, Johnston, TP, Sahebkar, A
BioMed research international. 2021;:5548310
Abstract
Arterial stiffness describes the increased rigidity of the arterial wall that occurs as a consequence of biological aging and several diseases. Numerous studies have demonstrated that parameters to assess arterial stiffness, especially pulse-wave velocity, are predictive of those individuals that will suffer cardiovascular morbidity and mortality. Statin therapy may be a pharmacological strategy to improve arterial elasticity. It has been shown that the positive benefits of statin therapy on cardiovascular disease is attributable not only to their lipid-lowering capacity but also to various pleiotropic effects, such as their anti-inflammatory, antiproliferative, antioxidant, and antithrombotic properties. Additionally, statins reduce endothelial dysfunction, improve vascular and myocardial remodeling, and stabilize atherosclerotic plaque. The aim of the present review was to summarize the evidence from human studies showing the effects of statins on arterial stiffness.

Coronary Artery Calcium: Where Do We Stand After Over 3 Decades?
Grundy, SM, Stone, NJ
The American journal of medicine. 2021;(9):1091-1095
Abstract
In 2018, cardiovascular society cholesterol guidelines recommended the use of coronary artery calcium to guide statin therapy in patients 40-79 years of age who are at intermediate risk by multiple risk factor equations (ie, estimated 10-year risk for atherosclerotic disease of 7.5%-19.9% but in whom statin benefit is uncertain). Many such patients have no coronary calcium and remain at <5% risk over the next decade; hence, statin therapy can be delayed until a repeat calcium scan is conducted. Exceptions include patients with severe hypercholesterolemia, diabetes, and a strong family history of atherosclerotic disease. If coronary calcium equals 1-99 Agatston units, the 10-year risk is borderline (5% to <7.5%) and statin therapy is optional pending a repeat scan. If coronary calcium equals 100-299 Agatston units, the patient is clearly statin eligible (7.5% to <20% 10-year risk). And finally, if coronary calcium is ≥300 Agatston units, a patient is at high risk and is a candidate for high-intensity statins. Risk factor analysis combined judiciously with coronary calcium scanning offers the strongest evidence-based approach to use of statins in primary prevention.

Intersection between Obesity, Dietary Selenium, and Statin Therapy in Brazil.
Watanabe, LM, Navarro, AM, Seale, LA
Nutrients. 2021;(6)
Abstract
Obesity is among the most alarming health concerns, impacting public health and causing a socioeconomic challenge, especially in developing countries like Brazil, where approximately one quart of the population presents obesity. As an established risk factor for numerous comorbidities with a multifactorial etiology, obesity is a consequence of energy-dense overfeeding, however with significant undernourishment, leading to excessive adipose tissue accumulation and dysfunction, dyslipidemia, and micronutrient deficiencies. About 60% of patients with obesity take statins, a cholesterol-lowering medication, to curb dyslipidemia, with ~10% of these patients presenting various myopathies as side effects. Statins act upon the rate-limiting enzyme of cholesterol biosynthesis in the liver, which is a pathway providing intermediates to the synthesis of selenoproteins, i.e., enzymes containing the micronutrient selenium. Statins have been postulated to negatively impact selenoprotein synthesis, particularly in conditions of selenium deficiency, and potentially implicated in the myopathies occurring as side effects of statins. The Brazilian population is prone to selenium deficiency, hence could be considered more susceptible to statin side effects. This review examines the specific consequences to the Brazilian population of the harmful intersection between obesity development and concomitant micronutrient deficiencies, particularly selenium, combined with statin treatment in the context of nutrition in Brazil.

Abstract
Due to an increasing number of older adults with (risk factors for) cardiovascular disease (CVD), the sum of older adults eligible for lipid-lowering drugs will increase. This has risen questions about benefits and harms of lipid-lowering therapy in older adults with a varying number of (cardiovascular) comorbidities and functional status. The heterogeneity in physical and functional health increases with age, leading to a much wider variety in cardiovascular risk and life expectancy than in younger adults. We suggest treatment decisions on hypercholesterolaemia in adults aged ≥75 years should shift from a strictly 10-year cardiovascular risk-driven approach to a patient-centred and lifetime benefit-based approach. With this, estimated 10-year risk of CVD should be placed into the perspective of life expectancy. Moreover, frailty and safety concerns must be taken into account for a risk-benefit discussion between clinician and patient. Based on the Dutch addendum 'Cardiovascular Risk Management in (frail) older adults', our approach offers more detailed information on when not to initiate or deprescribe therapy than standard guidelines. Instead of using traditional risk estimating tools which tend to overestimate risk of CVD in older adults, use a competing risk adjusted, older adults-specific risk score (available at https://u-prevent.com). By filling in a patient's (cardiovascular) health profile (eg, cholesterol, renal function), the tool estimates risk of CVD and models the effect of medication in terms of absolute risk reduction for an individual patient. Using this tool can guide doctors and patients in making shared decisions on initiating, continuing or deprescribing lipid-lowering therapy.

Abstract
PURPOSE OF REVIEW We aimed to summarize recent guidelines, position papers, and high-quality clinical research relating the use of nutraceuticals in the management of individuals at high risk of atherosclerotic cardiovascular disease. RECENT FINDINGS It is essential that individuals at high risk of cardiovascular disease receive guideline-directed evidence-based therapies to reduce their risk of morbidity and mortality from cardiovascular events. Compared with conventional therapeutics, nutraceuticals have undergone relatively little investigation in randomized controlled trials. Thus, recommendations for nutraceuticals in international guidelines are rare, and nutraceuticals should not be used preferentially in place of statins. Nevertheless, recent position papers from the International Lipid Expert Panel and clinical evidence from studies of triglyceride reduction by polyunsaturated fatty acid administration demonstrate that nutraceuticals do have an important role in optimizing therapy in individuals at high risk of cardiovascular disease. Roles for nutraceuticals include as follows: (1) managing residual risk associated with lipids other than low-density lipoprotein cholesterol (LDL-C); (2) managing non-lipid-mediated residual risk; (3) optimizing LDL-C treatment in statin intolerance; (4) optimizing LCL-C treatment when add-on therapies for statins are not available; (5) as adjuncts to lifestyle for individuals at high lifetime risk of atherosclerotic cardiovascular disease (ASCVD). The strength of evidence for each of these applications is variable. In addition to guideline-directed therapeutics, nutraceuticals may have roles in optimizing preventative therapy and targeting residual risk in individuals at high risk of ASCVD. Application of Good Manufacturing Practice and randomized controlled trials when producing and evaluating nutraceuticals will expand the armoury of evidence-based agents for the prevention of ASCVD.

Abstract
BACKGROUND AND AIMS Morbidity and mortality from coronavirus disease 2019 (COVID-19) is higher among people with diabetes mellitus (DM), hypertension, and cardiovascular disease (CVD). Statins are used in the majority of people with DM and CVD. This mini-review discusses the current understanding of benefit-risk ratio of use of statins in COVID-19. METHODS We searched PubMed database using specific keywords related to our aims till June 12, 2020. Full text of relevant articles published in English language were retrieved and reviewed. RESULTS Statins, with their immunomodulatory, anti-inflammatory, anti-thrombotic, and anti-oxidant properties, have the potential to reduce severity of lung injury in, and mortality from, severe acute respiratory syndrome-coronavirus 2 (SARS-CoV2) infections. Statin-induced upregulation of angiotensin-converting enzyme-2 (ACE2) has the potential to reduce lung injury from excess angiotensin II. By disrupting lipid rafts, statins have the potential to reduce viral entry into cells. However, benefit-risk ratio of its complex interaction with MYD88 gene expression on outcomes in COVID-19, and the putative role of low serum LDL cholesterol in increasing severity of SARS-CoV2 infection need further clarification. CONCLUSIONS People with COVID-19, who are already on statins for an underlying co-morbid condition, should continue on it unless there are specific contraindications. De-novo use of statins in people with COVID-19 with no underlying co-morbidity might be beneficial but awaits substantiation in clinical trials; till that time, de novo use of statins in COVID 19 should be limited to a clinical trial setting.

Familial hypercholesterolemia: Detect, treat, and ask about family.
Shah, NP, Ahmed, HM, Wilson Tang, WH
Cleveland Clinic journal of medicine. 2020;(2):109-120
Abstract
Familial hypercholesterolemia is an autosomal dominant disorder that affects the metabolism of low-density lipo-protein cholesterol (LDL-C) through mutations in the gene for LDL receptor (LDLR), and less commonly in those for apolipoprotein B (APOB), proprotein convertase subtili-sin-kexin type 9 (PCSK9), and others. Patients with these mutations have elevated plasma levels of LDL-C and, as a result, an increased risk of atherosclerotic cardiovascular disease beginning in childhood, leading to significant risk of illness and death.
