RESUMO
Adverse cardiovascular (CV) events have declined in Western countries due at least in part to aggressive risk factor control, including dyslipidemia management. The American and European (Western) dyslipidemia treatment guidelines have contributed significantly to the reduction in atherosclerotic cardiovascular disease (ASCVD) incidence in the respective populations. However, their direct extrapolation to Indian patients does not seem appropriate for the reasons described below. In the US, mean low-density lipoprotein cholesterol (LDL-C) levels have markedly declined over the last 2 decades, correlating with a proportional reduction in CV events. Conversely, poor risk factor control and dyslipidemia management have led to increased CV and coronary artery disease (CAD) mortality rates in India. The population-attributable risk of dyslipidemia is about 50% for myocardial infarction, signifying its major role in CV events. In addition, the pattern of dyslipidemia in Indians differs considerably from that in Western populations, requiring unique strategies for lipid management in Indians and modified treatment targets. The Lipid Association of India (LAI) recognized the need for tailored LDL-C targets for Indians and recommended lower targets compared to Western guidelines. For individuals with established ASCVD or diabetes with additional risk factors, an LDL-C target of <50 mg/dL was recommended, with an optional target of ≤30 mg/dL for individuals at extremely high risk. There are several reasons that necessitate these lower targets. In Indian subjects, CAD develops 10 years earlier than in Western populations and is more malignant. Additionally, Indians experience higher CAD mortality despite having lower basal LDL-C levels, requiring greater LDL-C reduction to achieve a comparable CV event reduction. The Indian Council for Medical Research-India Diabetes study described a high prevalence of dyslipidemia among Indians, characterized by relatively lower LDL-C levels, higher triglyceride levels, and lower high-density lipoprotein cholesterol (HDL-C) levels compared to Western populations. About 30% of Indians have hypertriglyceridemia, aggravating ASCVD risk and complicating dyslipidemia management. The levels of atherogenic triglyceride-rich lipoproteins, including remnant lipoproteins, are increased in hypertriglyceridemia and are predictive of CV events. Hypertriglyceridemia is also associated with higher levels of small, dense LDL particles, which are more atherogenic, and higher levels of apolipoprotein B (Apo B), reflecting a higher burden of circulating atherogenic lipoprotein particles. A high prevalence of low HDL-C, which is often dysfunctional, and elevated lipoprotein(a) [Lp(a)] levels further contribute to the heightened atherogenicity and premature CAD in Indians. Considering the unique characteristics of atherogenic dyslipidemia in Indians, lower LDL-C, non-HDL-C, and Apo B goals compared to Western guidelines are required for effective control of ASCVD risk in Indians. South Asian ancestry is identified as a risk enhancer in the American lipid management guidelines, highlighting the elevated ASCVD risk of Indian and other South Asian individuals, suggesting a need for more aggressive LDL-C lowering in such individuals. Hence, the LDL-C goals recommended by the Western guidelines may be excessively high for Indians and could result in significant residual ASCVD risk attributable to inadequate LDL-C lowering. Further, the results of Mendelian randomization studies have shown that lowering LDL-C by 5-10 mg/dL reduces CV risk by 8-18%. The lower LDL-C targets proposed by LAI can yield these incremental benefits. In conclusion, Western LDL-C targets may not be suitable for Indian subjects, given the earlier presentation of ASCVD at lower LDL-C levels. They may result in greater CV events that could otherwise be prevented with lower LDL-C targets. The atherogenic dyslipidemia in Indian individuals necessitates more aggressive LDL-C and non-HDL-C lowering, as recommended by the LAI, in order to stem the epidemic of ASCVD in India.

Anaplastic thyroid cancer (ATC) is the most aggressive thyroid cancer, with very limited treatment options. Mutations of p53 are associated with lethal outcomes of ATC. In this study, we tested the hypothesis that wild type p53 (WTp53) mitigates its aggressive progression. We used human 8505C cells (from human ATC tumors) as a model, harboring a BRAFV600E mutation and single of mutated p53C742G allele. We exogenously expressed WTp53 or mutant p53C742G into 8505C cells (8505C-WTp53 or 8505C-MTp53, respectively). The expressed WTp53 inhibited cell proliferation, decreased cell migration, and induced apoptosis via induction of proapoptotic WTp53 target BAX and PUMA genes in vitro. Mouse xenograft studies showed suppression of tumors induced by 8505C-WTp53 but not by 8505C-MTp53 cells. Consistent with in vitro findings, WTp53 inhibited proliferation of tumor cells, evidenced by decreased proliferation marker Ki-67 in tumors. WTp53 also induced apoptosis in xenograft tumors as shown by increased cleaved caspase-3 proteins and pro-apoptotic regulators, BAX and PUMA. Single cells RNA-sequencing (scRNA-seq) of tumors induced by 8505C, 8505C-WTp53, and 8505C-MTp53 cells demonstrated differential expression gene (DEG) patterns between 8505C-WTp53 and 8505C tumors. DEGs analysis identified alteration of multiple pathways, leading to attenuating the oncogenic actions of mutant p53. The discovery of the suppression of TNFα via NFκB pathway topped the pathways list, resulting in subduing the deleterious inflammatory responses caused by mutant p53. Our findings that exogenously expressed WTp53 could counter act the oncogenic actions of p53 has heightened the feasibility of using CRISPR/Cas9 genome editing to modify the p53 alleles for potential treatment of ATC.
RESUMO
Pancreatic adenocarcinoma (PDAC) is one the most intractable cancers, in part due to its highly inflammatory microenvironment and paucity of infiltrating dendritic cells (DCs). Here, we find that genetic ablation or antibody blockade of tumor necrosis factor receptor 1 (TNFR1) enhanced intratumor T cell activation and slowed PDAC growth. While anti-PD-1 checkpoint inhibition alone had little effect, it further enhanced intratumor T cell activation in combination with anti-TNFR1. The major cellular alteration in the tumor microenvironment in the absence of TNFR1 signaling was a large increase in DC number and immunostimulatory phenotype. This may reflect a direct effect on DCs, because TNF induced TNFR1-dependent apoptosis of bone-marrow-derived DCs. The therapeutic response to anti-TNFR1 alone was superior to the combination of DC-activating agonistic anti-CD40 and Flt3 ligand (Flt3L). These observations suggest that targeting TNFR1, perhaps in concert with other strategies that promote DC generation and mobilization, may have therapeutic benefits.

Low response rate, treatment relapse, and resistance remain key challenges for cancer treatment with immune checkpoint blockade (ICB). Here we report that loss of specific tumor suppressors (TS) induces an inflammatory response and promotes an immune suppressive tumor microenvironment. Importantly, low expression of these TSs is associated with a higher expression of immune checkpoint inhibitory mediators. Here we identify, by using in vivo CRISPR/Cas9 based loss-of-function screening, that NF1, TSC1, and TGF-ß RII as TSs regulating immune composition. Loss of each of these three TSs leads to alterations in chromatin accessibility and enhances IL6-JAK3-STAT3/6 inflammatory pathways. This results in an immune suppressive landscape, characterized by increased numbers of LAG3+ CD8 and CD4 T cells. ICB targeting LAG3 and PD-L1 simultaneously inhibits metastatic progression in preclinical triple negative breast cancer (TNBC) mouse models of NF1-, TSC1- or TGF-ß RII- deficient tumors. Our study thus reveals a role of TSs in regulating metastasis via non-cell-autonomous modulation of the immune compartment and provides proof-of-principle for ICB targeting LAG3 for patients with NF1-, TSC1- or TGF-ß RII-inactivated cancers.

INTRODUCTION: Coronary artery calcium (CAC) scans contain useful information beyond the Agatston CAC score that is not currently reported. We recently reported that artificial intelligence (AI)-enabled cardiac chambers volumetry in CAC scans (AI-CAC™) predicted incident atrial fibrillation in the Multi-Ethnic Study of Atherosclerosis (MESA). In this study, we investigated the performance of AI-CAC cardiac chambers for prediction of incident heart failure (HF). METHODS: We applied AI-CAC to 5750 CAC scans of asymptomatic individuals (52% female, White 40%, Black 26%, Hispanic 22% Chinese 12%) free of known cardiovascular disease at the MESA baseline examination (2000-2002). We used the 15-year outcomes data and compared the time-dependent area under the curve (AUC) of AI-CAC volumetry versus NT-proBNP, Agatston score, and 9 known clinical risk factors (age, gender, diabetes, current smoking, hypertension medication, systolic and diastolic blood pressure, LDL, HDL for predicting incident HF over 15 years. RESULTS: Over 15 years of follow-up, 256 HF events accrued. The time-dependent AUC [95% CI] at 15 years for predicting HF with AI-CAC all chambers volumetry (0.86 [0.82,0.91]) was significantly higher than NT-proBNP (0.74 [0.69, 0.77]) and Agatston score (0.71 [0.68, 0.78]) (p â< â0.0001), and comparable to clinical risk factors (0.85, p â= â0.4141). Category-free Net Reclassification Index (NRI) [95% CI] adding AI-CAC LV significantly improved on clinical risk factors (0.32 [0.16,0.41]), NT-proBNP (0.46 [0.33,0.58]), and Agatston score (0.71 [0.57,0.81]) for HF prediction at 15 years (p â< â0.0001). CONCLUSION: AI-CAC volumetry significantly outperformed NT-proBNP and the Agatston CAC score, and significantly improved the AUC and category-free NRI of clinical risk factors for incident HF prediction.

Angiogenesis is a critical physiological response to ischemia but becomes pathological when dysregulated and driven excessively by inflammation. We recently identified a novel angiogenic role for tripartite-motif-containing protein 2 (TRIM2) whereby lentiviral shRNA-mediated TRIM2 knockdown impaired endothelial angiogenic functions in vitro. This study sought to determine whether these effects could be translated in vivo and to determine the molecular mechanisms involved. CRISPR/Cas9-generated Trim2-/- mice that underwent a periarterial collar model of inflammation-induced angiogenesis exhibited significantly less adventitial macrophage infiltration relative to wildtype (WT) littermates, concomitant with decreased mRNA expression of macrophage marker Cd68 and reduced adventitial proliferating neovessels. Mechanistically, TRIM2 knockdown in endothelial cells in vitro attenuated inflammation-driven induction of critical angiogenic mediators, including nuclear HIF-1α, and curbed the phosphorylation of downstream effector eNOS. Conversely, in a hindlimb ischemia model of hypoxia-mediated angiogenesis, there were no differences in blood flow reperfusion to the ischemic hindlimbs of Trim2-/- and WT mice despite a decrease in proliferating neovessels and arterioles. TRIM2 knockdown in vitro attenuated hypoxia-driven induction of nuclear HIF-1α but had no further downstream effects on other angiogenic proteins. Our study has implications for understanding the role of TRIM2 in the regulation of angiogenesis in both pathophysiological contexts.

INTRODUCTION: We evaluated surgical trends, perioperative management evolution, and oncologic outcomes in patients who underwent radical nephroureterectomy (RNU) for upper tract urothelial carcinoma (UTUC) at a tertiary cancer center over a 24-year period. METHODS: Between 1995 and 2018, we evaluated 743 consecutive patients with UTUC who underwent RNU. Generalized additive models were used to estimate the associations between date of surgery and continuous outcomes using a linear model, dichotomous outcomes using a logit link, categorical outcomes using multinomial models, and 2- and 5-year survival outcomes using Cox proportional hazards models. RESULTS: Over the study period, preoperative diagnostic endoscopic biopsies increased from 10% to 66%, along with the proportion of patients who underwent RNU for high-grade disease from 55% to 91%. The rate of open RNU declined from 100% to 56% with a rise in minimally invasive approaches. Median lymph node yield increased with more retroperitoneal lymph node dissections performed. Neoadjuvant chemotherapy utilization increased with a contemporary utilization rate of 32%, coinciding with an increase in pT0 rate from 2% to 8%. Cancer-specific survival probabilities improved over the study period, while metastasis-free and overall survival remained stable. CONCLUSIONS: We found several changes in treatment patterns and outcomes for patients with UTUC over the past 2 decades. How individual alterations in management factors, such as patient selection, perioperative chemotherapy, lymphadenectomy, and salvage therapies, impact patient outcomes is challenging in the setting of multiple overlapping practice changes for this rare disease and warrants further investigation.

BACKGROUND: The American Heart Association (AHA), in conjunction with the National Institutes of Health, annually reports the most up-to-date statistics related to heart disease, stroke, and cardiovascular risk factors, including core health behaviors (smoking, physical activity, nutrition, sleep, and obesity) and health factors (cholesterol, blood pressure, glucose control, and metabolic syndrome) that contribute to cardiovascular health. The AHA Heart Disease and Stroke Statistical Update presents the latest data on a range of major clinical heart and circulatory disease conditions (including stroke, brain health, complications of pregnancy, kidney disease, congenital heart disease, rhythm disorders, sudden cardiac arrest, subclinical atherosclerosis, coronary heart disease, cardiomyopathy, heart failure, valvular disease, venous thromboembolism, and peripheral artery disease) and the associated outcomes (including quality of care, procedures, and economic costs). METHODS: The AHA, through its Epidemiology and Prevention Statistics Committee, continuously monitors and evaluates sources of data on heart disease and stroke in the United States and globally to provide the most current information available in the annual Statistical Update with review of published literature through the year before writing. The 2024 AHA Statistical Update is the product of a full year's worth of effort in 2023 by dedicated volunteer clinicians and scientists, committed government professionals, and AHA staff members. The AHA strives to further understand and help heal health problems inflicted by structural racism, a public health crisis that can significantly damage physical and mental health and perpetuate disparities in access to health care, education, income, housing, and several other factors vital to healthy lives. This year's edition includes additional global data, as well as data on the monitoring and benefits of cardiovascular health in the population, with an enhanced focus on health equity across several key domains. RESULTS: Each of the chapters in the Statistical Update focuses on a different topic related to heart disease and stroke statistics. CONCLUSIONS: The Statistical Update represents a critical resource for the lay public, policymakers, media professionals, clinicians, health care administrators, researchers, health advocates, and others seeking the best available data on these factors and conditions.

Multiple myeloma (MM) is a rarely curable malignancy of plasma cells. MM expresses B cell maturation antigen (BCMA). We developed a fully human anti-BCMA chimeric antigen receptor (CAR) with a heavy-chain-only antigen-recognition domain, a 4-1BB domain, and a CD3ζ domain. The CAR was designated FHVH33-CD8BBZ. We conducted the first-in-humans clinical trial of T cells expressing FHVH33-CD8BBZ (FHVH-T). Twenty-five patients with relapsed MM were treated. The stringent complete response rate (sCR) was 52%. Median progression-free survival (PFS) was 78 weeks. Of 24 evaluable patients, 6 (25%) had a maximum cytokine-release syndrome (CRS) grade of 3; no patients had CRS of greater than grade 3. Most anti-MM activity occurred within 2-4 weeks of FHVH-T infusion as shown by decreases in the rapidly changing MM markers serum free light chains, urine light chains, and bone marrow plasma cells. Blood CAR+ cell levels peaked during the time that MM elimination was occurring, between 7 and 15 days after FHVH-T infusion. C-C chemokine receptor type 7 (CCR7) expression on infusion CD4+ FHVH-T correlated with peak blood FHVH-T levels. Single-cell RNA sequencing revealed a shift toward more differentiated FHVH-T after infusion. Anti-CAR antibody responses were detected in 4 of 12 patients assessed. FHVH-T has powerful, rapid, and durable anti-MM activity.

Alkyl isonitriles, R-NC, have previously been shown to ligate the heme (haem) iron of cytochromes P450 in both accessible oxidation states (ferrous, Fe2+, and ferric, Fe3+). Herein, the preparation of four steroid-derived isonitriles and their interactions with several P450s, including the steroidogenic CYP17A1 and CYP106A2, as well as the more promiscuous drug metabolizers CYP3A4 and CYP2D6, is described. It was found that successful ligation of the heme iron by the isonitrile functionality for a given P450 depends on both the position and stereochemistry of the isonitrile on the steroid skeleton. Spectral studies indicate that isonitrile ligation of the ferric heme is stable upon reduction to the ferrous form, with reoxidation resulting in the original complex. A crystallographic structure of CYP17A1 with an isonitrile derived from pregnanalone further confirmed the interaction and identified the absolute stereochemistry of the bound species.
RESUMO
Cardiovascular diseases (CVDs) are the leading causes of morbidity and mortality in individuals with type 2 diabetes mellitus (T2DM). Secular changes in CVD outcomes have occurred over the past few decades, mainly due to a decline in the incidence of ischaemic heart disease. The onset of T2DM at a young age (<40 years), leading to a greater number of life-years lost, has also become increasingly common. Researchers are now looking beyond established risk factors in patients with T2DM towards the role of ectopic fat and, potentially, haemodynamic abnormalities in mediating important outcomes (such as heart failure). T2DM confers a wide spectrum of risk and is not necessarily a CVD risk equivalent, indicating the importance of risk assessment strategies (such as global risk scoring, consideration of risk-enhancing factors and assessment of subclinical atherosclerosis) to inform treatment. Data from epidemiological studies and clinical trials demonstrate that successful control of multiple risk factors can reduce the risk of CVD events by ≥50%; however, only ≤20% of patients achieve targets for risk factor reduction (plasma lipid levels, blood pressure, glycaemic control, body weight and non-smoking status). Improvements in composite risk factor control with lifestyle management (including a greater emphasis on weight loss interventions) and evidence-based generic and novel pharmacological therapies are therefore needed when the risk of CVD is high.

Epithelial ovarian cancer (EOC) remains the fifth leading cause of cancer-related death in women worldwide, partly due to the survival of chemoresistant, stem-like tumor-initiating cells (TICs) that promote disease relapse. We previously described a role for the NF-κB pathway in promoting TIC chemoresistance and survival through NF-κB transcription factors (TFs) RelA and RelB, which regulate genes important for the inflammatory response and those associated with cancer, including microRNAs (miRNAs). We hypothesized that NF-κB signaling differentially regulates miRNA expression through RelA and RelB to support TIC persistence. Inducible shRNA was stably expressed in OV90 cells to knockdown RELA or RELB; miR-seq analyses identified differentially expressed miRNAs hsa-miR-452-5p and hsa-miR-335-5p in cells grown in TIC versus adherent conditions. We validated the miR-seq findings via qPCR in TIC or adherent conditions with RELA or RELB knocked-down. We confirmed decreased expression of hsa-miR-452-5p when either RELA or RELB were depleted and increased expression of hsa-miR-335-5p when RELA was depleted. Either inhibiting miR-452-5p or mimicking miR-335-5p functionally decreased the stem-like potential of the TICs. These results highlight a novel role of NF-κB TFs in modulating miRNA expression in EOC cells, thus opening a better understanding toward preventing recurrence of EOC.

PURPOSE: Neoadjuvant chemotherapy (NAC) has proven survival benefits for patients with invasive urothelial carcinoma of the bladder, yet its role for upper tract urothelial carcinoma (UTUC) remains undefined. We conducted a multicenter, single-arm, phase II trial of NAC with gemcitabine and split-dose cisplatin (GC) for patients with high-risk UTUC before extirpative surgery to evaluate response, survival, and tolerability. METHODS: Eligible patients with defined criteria for high-risk localized UTUC received four cycles of split-dose GC before surgical resection and lymph node dissection. The primary study end point was rate of pathologic response (defined as < ypT2N0). Secondary end points included progression-free survival (PFS), overall survival (OS), and safety and tolerability. RESULTS: Among 57 patients evaluated, 36 (63%) demonstrated pathologic response (95% CI, 49 to 76). A complete pathologic response (ypT0N0) was noted in 11 patients (19%). Fifty-one patients (89%) tolerated at least three complete cycles of split-dose GC, 27 patients (47%) tolerated four complete cycles, and all patients proceeded to surgery. With a median follow up of 3.1 years, 2- and 5-year PFS rates were 89% (95% CI, 81 to 98) and 72% (95% CI, 59 to 87), while 2- and 5-year OS rates were 93% (95% CI, 86 to 100) and 79% (95% CI, 67 to 94), respectively. Pathologic complete and partial responses were associated with improved PFS and OS compared with nonresponders (≥ ypT2N any; 2-year PFS 100% and 95% v 76%, P < .001; 2-year OS 100% and 100% v 80%, P < .001). CONCLUSION: NAC with split-dose GC for high-risk UTUC is a well-tolerated, effective therapy demonstrating evidence of pathologic response that is associated with favorable survival outcomes. Given that these survival outcomes are superior to historical series, these data support the use of NAC as a standard of care for high-risk UTUC, and split-dose GC is a viable option for NAC.

Background: Prior studies support the utility of high sensitivity troponin I (hsTnI) for cardiovascular disease (CVD) risk stratification among asymptomatic populations; however, only two prior studies examined women separately. The association between hsTnI and breast arterial calcification is unknown. Methods: Cohort study of 2896 women aged 60-79 years recruited after attending mammography screening between 10/2012 and 2/2015. BAC status (presence versus absence) and quantity (calcium mass mg) was determined using digital mammograms. Pre-specified endpoints were incident coronary heart disease (CHD), ischemic stroke, heart failure and its subtypes and all CVD. Results: After 7.4 (SD = 1.7) years of follow-up, 51 CHD, 30 ischemic stroke and 46 heart failure events were ascertained. At a limit of detection of 1.6 ng/L, 98.3 of the cohort had measurable hsTnI concentration. HsTnI in the 4-10 ng/L range were independently associated of CHD (adjusted hazard ratio[aHR] = 2.78; 95% CI, 1.48-5.22; p = 0.002) and all CVD (aHR = 2.06; 95% CI, 1.37-3.09; p = 0.0005) and hsTnI over 10 ng/L was independently associated with CHD (aHR = 4.75; 95% CI, 1.83-12.3; p = 0.001), ischemic stroke (aHR = 3.81; 95% CI, 1.22-11.9; p = 0.02), heart failure (aHR = 3.29; 95% CI, 1.33-8.13; p = 0.01) and all CVD (aHR = 4.78; 95% CI, 2.66-8.59; p < 0.0001). No significant association was found between hsTnI and BAC. Adding hsTnI to a model containing the Pooled Cohorts Equation resulted in significant and clinical important improved calibration, discrimination (Δ Cindex = 6.5; p = 0.02) and reclassification (bias-corrected clinical NRI = 0.18; 95% CI, -0.13-0.49 after adding hsTnI categories). Conclusions: Our results support the consideration of hsTnI as a risk enhancing factor for CVD in asymptomatic women that could drive preventive or therapeutic decisions.
RESUMO
Introduction: We sought to better understand the baseline knowledge and practices of the general population regarding testicular cancer (TC) and testicular self-examination (TSE) in an effort to understand whether current screening guidelines reflect their viewpoint. The U.S. Preventive Services Task Force (USPSTF) currently recommends against TSE for TC screening due to a lack of data to support a benefit. Early detection of TC may reduce the required burden of therapy and associated long-term toxicities. Methods: This was a cross-sectional survey study. Participants (median age 33 years, IQR 28-39) were recruited via Amazon Mechanical Turk, a validated crowdsourcing platform used to recruit minimally compensated participants. Results: A total of 250 men rated themselves as "somewhat unknowledgeable" about TC, with no respondents considering themselves "very knowledgeable." Only 26.4% of men knew that TC was curable most of the time. Despite 90.8% of men feeling that their doctor had some role in discussing TC/TSE, only 17.2% had discussed these topics with their doctor. Even after being informed of the rationale behind USPSTF recommendations, only 8% of men thought that potential false positives of TSE would be more important than the rare chance of finding early TC. Conclusions: American men do not feel knowledgeable about TC, have a favorable attitude toward TSE and want their doctor to discuss these topics. Shared decision making regarding TC screening is warranted given the low risk of harm and patient interest, and continued accrual of data on this topic is necessary given the lack of prospective work to date.
RESUMO
Lipid-lowering therapy plays a crucial role in reducing adverse cardiovascular (CV) events in patients with established atherosclerotic cardiovascular disease (ASCVD) and familial hypercholesterolemia. Lifestyle interventions along with high-intensity statin therapy are the first-line management strategy followed by ezetimibe. Only about 20-30% of patients who are on maximally tolerated statins reach recommended low-density lipoprotein cholesterol (LDL-C) goals. Several factors contribute to the problem, including adherence issues, prescription of less than high-intensity statin therapy, and de-escalation of statin dosages, but in patients with very high baseline LDL-C levels, including those with familial hypercholesterolemia and those who are intolerant to statins, it is critical to expand our arsenal of LDL-C-lowering medications. Moreover, in the extreme risk group of patients with an LDL-C goal of ≤30 mg/dL according to the Lipid Association of India (LAI) risk stratification algorithm, there is a significant residual risk requiring the addition of non-statin drugs to achieve LAI recommended targets. This makes bempedoic acid a welcome addition to the existing non-statin therapies such as ezetimibe, bile acid sequestrants, and PCSK9 inhibitors. A low frequency of muscle-related side effects, minimal drug interactions, a significant reduction in high-sensitivity C-reactive protein (hsCRP), and a lower incidence of new-onset or worsening diabetes make it a useful adjunct for LDL-C lowering. However, the CV outcomes trial results are still pending. In this LAI consensus document, we discuss the pharmacology, indications, contraindications, advantages, and evidence-based recommendations for the use of bempedoic acid in clinical practice.

Non-communicable diseases, particularly cardiovascular diseases, are the leading cause of decreased life expectancy and death in Latin America and the Caribbean. Although a lifestyle, which includes no tobacco use, good nutrition, and regular physical activity is touted as key to health, the environmental, racial, social and economic conditions, which underpin lifestyle are often ignored or considered only secondarily. Placing the main responsibility on a patient to change their lifestyle or to simply comply with pharmacological treatment ignores the specific conditions in which the individual lives. Furthermore, there are major disparities in access to both healthy living conditions as well as access to medical care. There is sufficient evidence to support advocating for policies that support healthy living, particularly healthy food choices. Progress is being made to improve the food environment with enactment of front of package nutritional labels. However, policies were enacted only after intense regional research and advocacy supporting their implementation. Government officials must rise above the pressures of commercial interests and support health-promoting policies or be exposed as self-interest groups themselves. Strong advocacy is required to persuade officials that all policies should take health into consideration both to improve lives and economies.

Globally, nearly 500 million adults currently have diabetes, which is expected to increase to approximately 700 million by 2040. Cardiovascular diseases (CVD), including coronary heart disease, stroke, heart failure, and peripheral arterial disease, are the principal causes of death in persons with diabetes. Key to the prevention of CVD is optimization of associated risk factors. However, few persons with diabetes are at recommended targets for key CVD risk factors including low-density lipoprotein-cholesterol (LDL-C), blood pressure, glycated hemoglobin, nonsmoking status, and body mass index. While lifestyle management forms the basis for the prevention and control of these risk factors, newer and existing pharmacologic approaches are available to optimize the potential for CVD risk reduction, particularly for the management of lipids, blood pressure, and blood glucose. For higher-risk patients, antiplatelet therapy is recommended. Medication for blood pressure, statins, and most recently, icosapent ethyl, have evidence for reducing CVD events in persons with diabetes. Newer medications for diabetes, including sodium glucose cotransporter 2 (SGLT2) inhibitors and glucagon-like peptide-1 receptor agonists, also reduce CVD and SGLT2 inhibitors in particular also reduce progression of kidney disease and reduce heart failure hospitalizations (HFHs). Most importantly, a multidisciplinary team is required to address the polypharmaceutical options to best reduce CVD risks persons with diabetes.

OBJECTIVE: To describe litigation patterns of transurethral surgery in the treatment of benign prostatic hyperplasia including verdicts, types of lawsuits, plaintiff claims, and timing of the claims. METHODS: Data was gathered by searching for litigation cases between January 1, 1980 and December 1, 2021 in the Westlaw legal database using keywords for transurethral surgeries for benign prostatic hyperplasia. Extracted data included case type, general description of the plaintiffs and defendants, plaintiff claims, and whether the claim involved preoperative, perioperative, or postoperative management, verdict, and indemnity awards. RESULTS: The Westlaw search yielded 44 unique cases after removing duplicate and irrelevant cases. The most common surgery resulting in a lawsuit was transurethral resection of the prostate (70%) and urologists were the most frequently named defendant (80%). The most common plaintiff claims were sexual dysfunction (36%), irritative lower urinary tract symptoms (32%), and lack of consent (27%). Among malpractice cases, the verdict was in favor of the defendant in most cases (71%) and among Eighth Amendment violation cases, the verdict was in favor of the defendant in every case. The average indemnity payment was $565,845 and the highest indemnity payment was $1,020,000. CONCLUSION: Complications of transurethral surgeries and lack of consent are common reasons for patient's filing a lawsuit. Healthcare providers should ensure patient understanding of surgical risks and thoroughly document the conversation. Providers should be aware of the causes for litigation among transurethral surgeries for benign prostatic hyperplasia and of the possibility of Eighth Amendment violation lawsuits when treating prison inmates.
