ABSTRACT

INTRODUCTION: Although the effect of rectal indomethacin in post-endoscopic retrograde cholangiopancreatography pancreatitis is well established, the effect of aspirin on acute pancreatitis (AP) is not well studied. We investigate the effect of aspirin on AP.

METHODS: We collected data from the National Inpatient Sample database from 2016 to 2020, to identify adult patients with acute pancreatitis. Patients were stratified into 2 groups, based on the presence of aspirin use. The primary outcome was mortality, while other outcomes were sepsis, shock, acute kidney injury (AKI), ICU admission, deep venous thrombosis (DVT), pulmonary embolism (PE), portal vein thrombosis (PVT), pseudocyst and ileus.

RESULTS: A total of 2.09 million patients met the inclusion criteria, of which 197 170 (9.41%) had long-term aspirin use. The majority of the patients with aspirin use were aged >65 years, male, White and had Medicare insurance. There was a higher incidence of biliary pancreatitis while rates of alcohol-induced pancreatitis were lower in patients with aspirin use. There was a lower incidence of mortality, sepsis, shock, PE, DVT, PVT and pseudocyst in patients with aspirin use. There was no difference in the incidence of ileus, while the incidence of AKI was higher. After adjusting for confounding factors, patients with aspirin use had a 23.6% lower risk of mortality.

DISCUSSION: Our results reveal a significant finding of aspirin's protective effect on AP in the US population. Our study is the largest study revealing an association between aspirin and AP. Further studies assessing the role of aspirin use in AP are warranted.

Risk factors for pulmonary cement embolism after percutaneous vertebroplasty and radiofrequency ablation for spinal metastases

Front Oncol. 2023 May 5;13:1129658. doi: 10.3389/fonc.2023.1129658. eCollection 2023.

ABSTRACT

OBJECTIVE: Pulmonary cement embolism is a rare but underestimated complication of vertebroplasty due to the relative lack of study and examination. This study aims to investigate the incidence of pulmonary cement embolism in patients with spinal metastasis who undergo PVP with RFA and to analyze the relative risk factors.

METHODS: A total of 47 patients were retrospectively included and classified into pulmonary cement embolism (PCE) group and non-pulmonary cement embolism (NPCE) group by comparing pre- and postoperative pulmonary CT scan images. The demographic and clinical information of the patients was obtained. Demographic data in the two groups were compared using the chi-square test for qualitative data and the unpaired t test for quantitative data. Multiple logistic regression analysis was used to identify risk factors related to pulmonary cement embolism.

RESULTS: Pulmonary cement embolism was detected in 11 patients (23.4%), and all patients were asymptomatic and followed up regularly. Risk analysis showed that multiple segments (≥3, p=0.022), thoracic vertebrae (p=0.0008), and unipedicular puncture approach (p=0.0059) were risk factors for pulmonary cement embolism. There was a high incidence of pulmonary cement embolism if bone cement leaked into the para vertebral venous plexus in the thoracic vertebra (p<0.0001).

CONCLUSION: The number of involved vertebrae, lesion location, and puncture approach are independent risk factors for pulmonary cement embolism. There was a high incidence of pulmonary cement embolism if bone cement leaked into the para vertebral venous plexus in the thoracic vertebra. Surgeons should consider these factors when formulating therapeutic strategies.

Long-term ambient air pollution and venous thromboembolism in a population-based Swedish cohort

Environ Pollut. 2023 May 18;331(Pt 1):121841. doi: 10.1016/j.envpol.2023.121841. Online ahead of print.

ABSTRACT

Air pollution is a major contributor to the global burden of disease and has been linked to several diseases and conditions, including cardiovascular disease. The biological mechanisms are related to inflammation and increased coagulability, factors that play an important role in the pathogenesis of venous thromboembolism (VTE, i.e., deep vein thrombosis or pulmonary embolism). This study investigates if long-term exposure to air pollution is associated with increased VTE incidence. The study followed 29 408 participants from the Malmö Diet and Cancer (MDC) cohort, which consists of adults aged 44-74 recruited in Malmö, Sweden between 1991 and 1996. For each participant, annual mean residential exposures to particulate matter <2.52.5) and <1010), nitrogen oxides (NOx) and black carbon (BC) from 1990 up to 2016 were calculated. Associations with VTE were analysed using Cox proportional hazard models for air pollution in the year of the VTE event (lag0) and the mean of the prior 1-10 years (lag1-10). Annual air pollution exposures for the full follow-up period had the following means: 10.8 μg/m3 for PM2.5, 15.8 μg/m3 for PM10, 27.7 μg/m3 for NOx, and 0.96 μg/m3 for BC. The mean follow-up period was 19.5 years, with 1418 incident VTE events recorded during this period. Exposure to lag1-10 PM2.5 was associated with an increased risk of VTE (HR 1.17 (95%CI 1.01-1.37)) per interquartile range (IQR) of 1.2 μg/m3 increase in PM2.5 exposure. No significant associations were found between other pollutants or lag0 PM2.5 and incident VTE. When VTE was divided into specific diagnoses, associations with lag1-10 PM2.5 exposure were similarly positive for deep vein thrombosis but not for pulmonary embolism. Results persisted in sensitivity analyses and in multi-pollutant models. Long-term exposure to moderate concentrations of ambient PM2.5 was associated with increased risks of VTE in the general population in Sweden.
