Benzene, a ubiquitous environmental pollutant and industrial chemical, has been identified as a carcinogen with a known association with lung cancer risk. This meta-analysis systematically reviews human studies investigating the relationship between benzene exposure and lung cancer risk. Through comprehensive literature search and statistical synthesis of available data, this review aims to provide a quantitative assessment of the magnitude of the association between benzene exposure and lung cancer risk across different populations and exposure levels. The findings of this meta-analysis contribute to our understanding of the carcinogenic potential of benzene and inform public health strategies aimed at reducing exposure to this hazardous substance.

Cancer diagnosis and treatment profoundly impact patients' physical and psychosocial well-being. Emerging research suggests a critical link between activity levels, sedentary behaviour and psychosocial outcomes in cancer patients. This review synthesizes existing literature on the relationship between activity, sedentary behaviour and psychosocial well-being in cancer patients. The findings highlight the beneficial effects of physical activity on psychosocial outcomes, including reduced anxiety, depression and improved quality of life, while sedentary behaviour is associated with poorer psychosocial functioning. Mechanisms underlying this relationship remain underexplored but may involve physiological, psychological and social pathways. Integrating assessments of activity and sedentary behaviour into routine clinical practice and implementing tailored interventions may optimize psychosocial outcomes and enhance overall well-being for cancer patients. Future research should focus on elucidating the underlying mechanisms and evaluating the effectiveness of interventions targeting activity and sedentary behaviour in improving psychosocial outcomes among cancer patients.

Uterine fibroids are a prevalent gynecological condition known to disproportionately affect women of African descent. This study examines the prevalence of uterine fibroids within a Chicago cohort predominantly comprising Black individuals. By analyzing medical records and community health surveys, we investigate the prevalence rates, demographic factors, clinical characteristics and healthcare disparities associated with uterine fibroids in this population. Our findings underscore the significant burden of uterine fibroids among Black women in Chicago, emphasizing the need for targeted interventions and improved access to healthcare resources. Understanding the epidemiology of uterine fibroids within this population is critical for addressing healthcare disparities and enhancing patient outcomes.
