Discovering the effect with the Zone Installation MethodTM (ZIMTM): The randomized manipulated test.
Compelling evidence has emerged from epidemiological and Mendelian randomization analyses relative to the causality of lipoprotein(a) [Lp(a)] in atherosclerotic cardiovascular diseases (ASCVD), being elevated Lp(a) a strong risk factor regardless of the reduction of LDL-C achieved by statins. So far, no specific available agent can lower Lp(a) to the extent required to achieve a cardiovascular (CV) benefit, i.e. approximately 100 mg/dL. The most recent outcomes trial FOURIER with evolocumab showed that a 25 nmol/L (12 mg/dL) reduction in Lp(a) corresponded to a 15% decrement in the relative risk of cardiovascular disease. The ODYSSEY OUTCOMES trial with alirocumab has been the first demonstrating that a reduction in Lp(a) associates with less major adverse cardiovascular events (MACE), i.e. hazard ratio 0.994 per 1 mg/dL decrement in Lp(a). The Lp(a) lowering effect driven by PCSK9 inhibition was confirmed in carriers of PCSK9 loss-of-function mutations in which Lp(a) and oxPL-apoB levels were decreased compared to non-carriers as was for a slight larger number of apo(a) Kringle IV repeats. Although PCSK9 inhibitors are not able to decrease Lp(a) to the extent required to achieve a CV benefit, their use has led to a higher discontinuation rate in lipoprotein apheresis in patients with progressive ASCVD and high plasma Lp(a).The CABANA trial is a randomized controlled study comparing catheter ablation vs. conventional medical therapy in atrial fibrillation (AF) patients. The results of the study showed that catheter ablation did not have a significant reduction of strokes, deaths, serious bleeding, or cardiac arrest compared to medical therapy. However, a significant improvement in AF recurrences, quality of life, and symptom relief has been shown after catheter ablation compared to drug therapy. The mixed results of the study emphasized an active controversy in the cardiology community on the interpretation of the data and their use in current clinical practice. In this review, we summarized the principal controversy points of the trial describing the strengths and weaknesses of the study design and analysis.Type 2 diabetes mellitus represents one of the most common chronic-degenerative diseases in modern society and is the cause of innumerable micro- and macrovascular complications that weigh on the national health system. Until a few years ago, there was no anti-diabetic drug that, in addition to lowering blood sugar, had an impact on cardiovascular risk in these patients. In this report, we will analyse the characteristics, contraindications, and evidence in favour of the use of two innovative categories of molecules that aim, for the first time in history, at controlling blood sugar levels and simultaneously lower cardiovascular risk in diabetics individuals the glucagon-like peptide receptor agonists and the sodium-glucose cotransporter 2 inhibitors.Patients with established cardiovascular (CV) disease may suffer further CV events, despite receiving optimal medical treatment. Although platelet inhibition plays a central role in the prevention of new events, the use of anticoagulant therapies to reduce events in atheromatous disease has, until recently, been overlooked. The recent Rivaroxaban for the Prevention of Major Cardiovascular Events in Coronary or Peripheral Artery Disease (COMPASS) trial showed that rivaroxaban 2.5 mg twice daily given with low-dose aspirin reduces the incidence of the composite endpoint of stroke, heart attack, and death in patients with stable coronary artery disease. Although there are some limitations to the study, COMPASS offers promising conclusions and may change secondary prevention in patients with stable CV disease. This article reviews the results of the COMPASS study and how these results may affect patient management in everyday clinical practice.Immunotherapy has revolutionized the treatment of metastatic renal cell carcinoma (RCC). This case evaluates the use of neoadjuvant immunotherapy for localized RCC in a patient with solitary functioning kidney. A retrospective chart review was conducted between September 2019 and January 2020 on a single patient. Before treatment, the tumor was 7 cm × 8 cm × 8.5 cm. The patient trialed nivolumab + ipilimumab then cabozantinib. The tumor shrunk to 6.3 cm × 5.5 cm and was removed via partial nephrectomy. This case demonstrates the efficacy of immunotherapy in neoadjuvant treatment of RCC. Expansion of guidelines could allow for patients with RCC to undergo partial nephrectomy.With increasing treatment options available, the management of locally advanced and metastatic prostate cancer (PCa) is growing more complex, nuanced, and individualized. Strategies for combining surgery, radiation, chemotherapy, and androgen deprivation therapy (ADT) continue to evolve, as do ADT and immunotherapy options. Additionally, multiple adjunctive agents for metastatic PCa have been recently approved or are pending approval. As the number of locally advanced and metastatic prostate cancers being diagnosed rises, so does the need to consider patients' clinical situations and personal preferences. This review discusses current and potential future approaches to managing locally advanced and metastatic PCa.To compare prostate biopsy (Pbx) characteristics before and after the 2012 United States Preventive Services Task Force (USPSTF) prostate cancer (PCa) screening guidelines, we completed a retrospective comparative analysis of 1703 sequential patients that had a Pbx in 2010 to 2012 (3 years) with 383 patients biopsied in 2018 and 310 patients biopsied in 2019. Data was collected on patient age, race, serum prostate specific antigen (PSA) level, digital rectal examination (DRE) results, total number of biopsies performed, and Gleason sum score (GSS). Data were analyzed to determine whether the 2012 USPSTF screening recommendations against PCa screening may have affected PCa characteristics. Three study groups were defined as Group A, Group B, and Group C. Group A represents Pbx prior to the 2012 USPSTF screening guidelines (2010-2012), Group B represents Pbx in 2018, and Group C represents Pbx in 2019. The patient population consisted of 73% Black men, 16% White men, and 11% men of other races. learn more The number of patients that had a biopsy in Groups A through C, respectively, were 567 patients/year, 383 patients/year, and 310 patients/year.
