Cardiovascular outcomes in breast cancer survivors: a systematic review and meta-analysis.

AIMS: It is unclear whether the future risk of cardiovascular events in breast cancer (Bc) survivors is greater than in the general population. This meta-analysis quantifies the risk of cardiovascular disease development in Bc patients, compared to the risk in a general matched cancer-free population, and reports the incidence of cardiovascular events in patients with Bc. METHODS AND RESULTS: We searched PubMed, Scopus, and Web of Science databases (up to 23 March 2022) for observational studies and post hoc analyses of randomized controlled trials. Cardiovascular death, heart failure (HF), atrial fibrillation (AF), coronary artery disease (CAD), myocardial infarction (MI), and stroke were the individual endpoints for our meta-analysis. We pooled incidence rates (IRs) and risk in hazard ratios (HRs), using random-effects meta-analyses. Heterogeneity was reported through the I2 statistic, and publication bias was examined using funnel plots and Egger's test in the meta-analysis of risk. One hundred and forty-two studies were identified in total, 26 (836 301 patients) relevant to the relative risk and 116 (2 111 882 patients) relevant to IRs. Compared to matched cancer-free controls, Bc patients had higher risk for cardiovascular death within 5 years of cancer diagnosis [HR = 1.09; 95% confidence interval (CI): 1.07, 1.11], HF within 10 years (HR = 1.21; 95% CI: 1.1, 1.33), and AF within 3 years (HR = 1.13; 95% CI: 1.05, 1.21). The pooled IR for cardiovascular death was 1.73 (95% CI 1.18, 2.53), 4.44 (95% CI 3.33, 5.92) for HF, 4.29 (95% CI 3.09, 5.94) for CAD, 1.98 (95% CI 1.24, 3.16) for MI, 4.33 (95% CI 2.97, 6.30) for stroke of any type, and 2.64 (95% CI 2.97, 6.30) for ischaemic stroke. CONCLUSION: Breast cancer exposure was associated with the increased risk for cardiovascular death, HF, and AF. The pooled incidence for cardiovascular endpoints varied depending on population characteristics and endpoint studied. REGISTRATION: CRD42022298741.

This work investigated the absolute and relative risk of cardiovascular outcomes in breast cancer survivors. Breast cancer was associated with a higher risk of cardiovascular death, heart failure (HF), and atrial fibrillation when compared to the general population.The incidence for cardiovascular death, HF, and coronary artery disease were 1.73, 4.44, and 4.29 per 1000 person-years, respectively.Clinicians should carefully assess breast cancer survivors for their cardiovascular risk factor profile and monitor their cardiovascular function.

Relation of Extracardiac Vascular Disease and Outcomes in Patients With Diabetes (1.1 Million) Hospitalized for Acute Myocardial Infarction.

The association between vascular disease and outcomes of patients with acute myocardial infarction (AMI) has not been well-defined in the diabetes mellitus (DM) population. All patients with DM presenting with AMI between October 2015 and December 2018 in the National Inpatient Sample database were stratified by number and site of extracardiac vascular comorbidity (cerebrovascular [CVD], renovascular, neural, retinal and peripheral [PAD] diseases). Multivariable logistic regression was used to determine the adjusted odds ratios (aORs) of in-hospital adverse outcomes and procedures. Of 1,116,670 patients with DM who were hospitalized for AMI, 366,165 had ≥1 extracardiac vascular comorbidity (32.8%). Patients with vascular disease had an increased aOR for mortality (aOR 1.05, 95% confidence interval [CI] 1.04 to 1.07), major adverse cardiovascular and cerebrovascular events (MACCEs) (aOR 1.19, 95% CI 1.18 to 1.21), stroke (aOR 1.72, 95% CI 1.68 to 1.76), and major bleeding (aOR 1.11, 95% CI 1.09 to 1.13) and had lower odds of receiving coronary angiography (CA) (aOR 0.90, 95% CI 0.90 to 0.91) and percutaneous coronary intervention (PCI) (aOR 0.82, 95% CI 0.82 to 0.83) than patients without extracardiac vascular disease. Patients with PAD had the highest odds of mortality (aOR 1.29, 95% CI 1.27 to 1.32), whereas patients with CVD had the greatest odds of MACCEs, stroke, and major bleeding (aOR 1.82, 95% CI 1.78 to 1.87, aOR 4.25, 95% CI 4.10 to 4.40, and aOR 1.51, 95% CI 1.45 to 1.57, respectively). Patients with DM presenting with AMI and concomitant extracardiac vascular disease were more likely to develop clinical outcomes and less likely to undergo CA or PCI. Patients with PAD had the highest risk of mortality, whereas patients with CVD had the greatest risk of MACCEs, stroke, and major bleeding.

Impact of malignancy on In-hospital mortality, stratified by the cause of admission: An analysis of 67 million patients from the National Inpatient Sample.

OBJECTIVE: To describe the patient characteristics and the reason for admission of patients with malignancy by malignancy, and to study mortality rates for the different causes of admissions among the different types of cancer. PATIENTS AND METHODS: Using the nationwide Inpatient Sampling (2015-2017) we examined the cause of admission and associated in-hospital mortality, stratified by presence and type of malignancy. Multivariable logistic regression models were used to examine the association between in-hospital mortality and malignancy sites for different primary admission causes. RESULTS: Out of 67 819 693 inpatient admissions, 8.8% had malignancy. Amongst those with malignancy, haematological malignancy was the most common (20.2%). The most common cause of admission amongst all cancers were malignancy-related admissions, where up to 57% of all colorectal admissions were malignancy-related. The most common non-malignancy cause of admission was infectious causes, which were most frequent among patients with haematological malignancy (18.4%). Patients with malignancy had higher crude mortality rates (5.7% vs 1.9%). Mortality rates were highest among patients with lung cancer (8.7%). Among all admissions, the adjusted rates of mortality were higher for patients with lung (OR 3.65, 95% CI [3.59-3.71]), breast (OR 2.06, 95% CI [1.99-2.13]), haematological (OR 1.79, 95% CI [1.76-1.82]) and colorectal (OR 1.71, 95% CI [1.66-1.76]) malignancies compared with patients with no malignancy. CONCLUSION: Our work highlights the need to consider the burden of cancer on our hospital services and consider how the prognostic impact of different types of admissions may relate to the type of cancer diagnosis and understand whether these differences relate to disparities in clinical care/treatments.

Comparison of Outcomes of Patients With Versus Without Chronic Liver Disease Undergoing Percutaneous Coronary Intervention.

There are limited data on the outcomes of chronic liver disease (CLD) patients admitted for percutaneous coronary intervention (PCI). All PCI hospitalizations from the Nationwide Inpatient Sample (2004 to 2015) were analyzed and stratified by the presence, cause and severity of CLD, as well as the indication for PCI. Multivariable logistic regression analysis was performed to determine the adjusted odds ratios (aOR) of in-hospital adverse outcomes in patients with CLD compared with those without CLD. Among 7,296,679 PCI admissions, 54,368 (0.7%) had a CLD diagnosis. Among patients with CLD, 36,853 (67.8%) had severe CLD. Patients with CLD had higher likelihood of adverse outcomes including major adverse cardiovascular and cerebrovascular events (MACCE) (aOR 1.25, 95%CI 1.20 to 1.30), mortality (aOR 1.43, 95%CI 1.35 to 1.51), major bleeding (aOR 2.22, 95%CI 2.12 to 2.32). When accounting for severity, only severe CLD subgroup was more likely to have MACCE and all-cause mortality compared to no-CLD patients (p <0.001). Among CLD etiologic subgroups, those with 'alcohol-related liver disease' and 'other CLD' were consistently more likely to develop MACCE, all-cause mortality and major bleeding in comparison to no-CLD patients, while 'chronic viral hepatitis' subgroup had only increased odds of major bleeding (p <0.001). In conclusion, CLD patients admitted for PCI are more likely to have worse in-hospital outcomes, particularly in the severe CLD subgroup and 'alcohol-related liver disease' and 'other CLD' etiologic subgroups.

Correlation between anti-malarial and anti-haemozoin activities of anti-malarial compounds.

BACKGROUND: Despite noticeable improvement in anti-malarial treatment, rapid growth of resistant malaria strains points out the need for continuous development of novel anti-malarials to fight the disastrous infection. Haemozoin is considered as a novel inhibitory pathway for new anti-malarial drugs, therefore, this study aimed to systematically review all articles investigating the correlation between anti-malarial and anti-haemozoin activities of anti-malarial compounds. METHODS: A literature search was conducted on 22 October 2017 in eight databases for relevant in vitro articles reporting the correlation between anti-malarial and anti-haemozoin of anti-malarial compounds, based on the constructed search terms and inclusion criteria. ToxRtool was used to assess quality of each study. RESULTS: A total of ten articles were included in the review. In vitro anti-malarial and anti-haemozoin activity had a good correlation for quinolines for sensitive strains (R2 ranging from 0.66 to 0.95) and xanthones (Spearman ρ = 0.886). However, these correlations were reached after removing some compounds which had non-detectable anti-malarial or anti-haemozoin effects. Other structures (acridines, pyrolidines) showed negligible correlation with Spearman ρ ranging from 0.095 to 0.381 for acridines, and r varying from 0.54 to 0.62 for pyrolidines. Some good correlations were only shown in a logarithmic manner or when the anti-malarial activity was normalized. CONCLUSION: The results raised a relative relationship between anti-haemozoin and in vitro anti-malarial activities. Some studies reported compounds that were effective in the inhibition of haemozoin formation, but failed to inhibit the parasite survival and vice versa. The correlation results in these studies were calculated after these compounds were removed from their analysis. The ability of anti-malarial compounds to accumulate inside the reaction site might strengthen their anti-malarial activity.

Examined and Positive Lymph Node Counts Are Associated with Mortality in Prostate Cancer: A Population-Based Analysis.

BACKGROUND: Prostate cancer (PCa) is the third leading cause of death from cancer in the United States. We aimed to disclose the prognostic values of examined (dissected) lymph node (ELN), negative lymph node (NLN), and positive (metastatic) lymph node (PLN) counts and lymph node (LNs) ratio in PCa patients. METHODS: We extracted data of PCa patients diagnosed between 2004 and 2015 from the Surveillance, Epidemiology, and End Results (SEER) program. We included patients with a histologically confirmed diagnosis having at least one ELN and with the PCa as the primary tumor only. RESULTS: We have included 96,064 patients. Multivariable Cox proportional hazards regression modelsdisclosed that patients having more ELNs were associated with better survival. However, we demonstrated that patients having more PLNs were associated with worse survival. Additionally, older age, unmarried patients, with Gleason's score of 8-10, T4 and M1 stages and those who received chemotherapy and/or radiation but did not receive surgery were significantly associated with worse PCa survival. CONCLUSIONS: We have disclosed several independent predictors affecting PCa patients including age, marital status, Gleason's score, T and N stages, having received therapy, surgery, and ELN and PLN counts. Moreover, we demonstrated that patients with lower ELN and higher PLN counts were a high-risk group. We strongly recommend adding the ELN and/or PLN counts into consideration during patient staging/treatment.

Association between pet ownership and cardiovascular risks and mortality: a systematic review and meta-analysis.

: The aim of the study was to determine the association between pet ownership and cardiovascular risk factors and mortality. Electronic search was conducted through nine databases including PubMed for relevant publications reporting cardiovascular events and mortality among pet owners. Meta-analysis was used to pool the results. Of a total of 2818 reports screened, 26 studies were included in our systematic review and meta-analysis. Higher survival rate was observed in the pet owners group after pooling nonadjusted and adjusted hazard ratios for cardiovascular mortality at 0.73 [95% confidence interval (CI) 0.62-0.86] and 0.81 (0.68-0.97), respectively. A similar trend was observed for the pooled nonadjusted hazard ratio for overall mortality 0.73 (0.62-0.87) but not the adjusted hazard ratio 0.40 (0.04-3.78). Cat owners have a reduction in cardiovascular mortality but not overall mortality after pooling the adjusted hazard ratio 0.79 (0.63-0.99) and 1.04 (0.90-1.21), respectively. However, no significant association between dog owners and survival rate was observed for overall and cardiovascular-specific mortality. Pet owners had significantly lower heart rate (mean difference 95% CI: -2.32 (-3.07 to -1.57), mean arterial pressure -2.60 (-4.25 to -0.95) and SBP -1.69 (-3.06 to -0.31) but not DBP -0.23 (-1.05 to 0.60). No significant difference was observed between pet owners and nonpet owners in prevalence of hypertension. Our study draws attention to the beneficial effects of the human--pet bond; therefore, we recommend pet acquisition for better cardiovascular outcomes after controlling for zoonotics and pet-induced allergies.
