Abstract Introduction Socioeconomic status significantly impacts the prognosis of patients with chronic diseases; however, there are few reports on its association with environmental risk factors. Purpose To assess the short-term exposure to air pollution's effect on mortality, including respiratory disease (RD) and cardiovascular disease (CVD) mortality, we also analyzed the modifying effect of residents' sex, age, and socioeconomic status. Methods The study covered a region of Poland inhabited by 8 million residents from 2011–2020 (80 million person-years of observation). Mortality (all-cause, CVD and RD) data were obtained from the Central Statistical Office, and pollutant concentration estimates were derived using the GEM-AQ model developed for all analyzed municipalities, providing high-quality geographic and temporal resolution. In the first stage, county-specific risk estimates (LAU-2 level) were calculated using a quasi-Poisson regression model, accounting for chronobiology, weather conditions, COVID-19 pandemic, influenza seasons etc. In the second stage, the county-specific results were aggregated using a multilevel random-effects meta-analysis. The study assessed the association between exposure to increased pollutant concentrations (PM2.5 and NO2) by 10 μg/m³ and mortality within 72 hours of exposure. Results A total of 831,246 deaths were recorded, including 377,374 and 45,380 deaths attributed to CVD and RD, respectively. The age at death was higher among CVD cases compared to RD (median 82 vs. 80 years, p<0.001). Men were more likely to die from RD (59.2%), whereas women accounted for the majority of CVD-related deaths (53.8%). Exposure to PM2.5 and NO2 significantly increased the risk of all cause death (by 5.5% and 6.2%, respectively), including CVD (both by 7.7%) and RD (by 9.3% and 9.8%, respectively) [Figures 1 and 2]. Both analyzed sex and age groups were affected by the negative effects of air pollutants in all analyzed outcomes. Residents of areas with low and medium socioeconomic status were more vulnerable to CVD-related deaths associated with PM2.5 exposure (pinteraction=0.026), as well as to all-cause mortality (pinteraction=0.02) and CVD mortality (pinteraction=0.007) associated with NO2 exposure. Conclusion Short-term exposure to air pollution might trigger acute CVD and RD leading to death. Air pollution also significantly increased all-cause mortality. Residents of areas with low and medium socioeconomic status may be more vulnerable to the effects of air pollution. Systemic interventions should prioritize regions with the lowest socioeconomic status.PM2.5 exposure and mortality.NO2 exposure and mortality.
Cancer and cardiovascular diseases (CVD) are among the leading causes of death worldwide. In response to the growing population of cancer patients and survivors with CVD, the sub-specialty of cardio-oncology has been developed to better optimise their care. Palpitations are one of the most common presenting complaints seen in the emergency room or by the primary care provider or cardiologist. Palpitations are defined as a rapid pulsation or abnormally rapid or irregular beating of the heart and present a complex diagnostic entity with no evidence-based guidelines currently available. Palpitations are a frequent occurrence in people with cancer, and investigations and treatment are comparable to that in the general population although there are some nuances. Cancer patients are at a higher risk of arrhythmogenic causes of palpitations and non-arrhythmogenic causes of palpitations. This review will appraise the literature with regards to the development and management of palpitations in the cancer patient.
