Review
CONTEXT
Bladder cancer (BC) is common worldwide and poses a significant public health challenge. External risk factors and the wider exposome (totality of exposure from external and internal factors) contribute significantly to the development of BC. Therefore, establishing a clear understanding of these risk factors is the key to prevention.
OBJECTIVE
To perform an up-to-date systematic review of BC's epidemiology and external risk factors.
EVIDENCE ACQUISITION
Two reviewers (I.J. and S.O.) performed a systematic review using PubMed and Embase in January 2022 and updated it in September 2022. The search was restricted to 4 yr since our previous review in 2018.
EVIDENCE SYNTHESIS
Our search identified 5177 articles and a total of 349 full-text manuscripts. GLOBOCAN data from 2020 revealed an incidence of 573 000 new BC cases and 213 000 deaths worldwide in 2020. The 5-yr prevalence worldwide in 2020 was 1 721 000. Tobacco smoking and occupational exposures (aromatic amines and polycyclic aromatic hydrocarbons) are the most substantial risk factors. In addition, correlative evidence exists for several risk factors, including specific dietary factors, imbalanced microbiome, gene-environment risk factor interactions, diesel exhaust emission exposure, and pelvic radiotherapy.
CONCLUSIONS
We present a contemporary overview of the epidemiology of BC and the current evidence for BC risk factors. Smoking and specific occupational exposures are the most established risk factors. There is emerging evidence for specific dietary factors, imbalanced microbiome, gene-external risk factor interactions, diesel exhaust emission exposure, and pelvic radiotherapy. Further high-quality evidence is required to confirm initial findings and further understand cancer prevention.
PATIENT SUMMARY
Bladder cancer is common, and the most substantial risk factors are smoking and workplace exposure to suspected carcinogens. On-going research to identify avoidable risk factors could reduce the number of people who get bladder cancer.

Frontiers in Immunology 2023This study aimed to explore the potential causal link between three specific types of occupational exposure on rheumatoid arthritis (RA) and ankylosing spondylitis (AS).
OBJECTIVE
This study aimed to explore the potential causal link between three specific types of occupational exposure on rheumatoid arthritis (RA) and ankylosing spondylitis (AS).
METHOD
A Two-sample Mendelian randomization (TSMR) analysis, comprising univariate MR (UVMR) and multivariate MR (MVMR) analyses, was performed to investigate the potential causal association between three types of occupational exposures, jobs involving mainly walking or standing (JWS), jobs involving heavy manual or physical work (JMP), and jobs involving shift work(JSW) on RA and AS. Genetic variants for genome-wide association studies (GWAS) of occupational exposure and AS were obtained from the UK Biobank. GWAS summary data for RA were obtained from FinnGen Biobank analysis. For UVMR, six methods of Inverse Variance Weighted (IVW), MR-Egger, Weighted Mode, Weighted Median, Simple Mode, MR pleiotropy residual sum, and outlier (MR-PRESSO) were used for the analysis. The MVMR was analyzed using the IVW model as well as the MR-Egger model.
RESULTS
The UVMR suggested no causal relationship between the three occupational exposure and RA [IVW: P=0.59,0.21,0.63] or AS [IVW: P=0.43,0.57,0.04], as did the bidirectional MR [IVW: P=0.73,0.70,0.16], [IVW: P=0.65,0.68,0.74]. Although unadjusted MVMR suggested a causal relationship between JMP and AS [IVW: OR = 1.01, 95% CI = 1.00- 1.02, p = 0.02], the adjusted MVMR denied this relationship and concluded that there was no causal relationship between the other occupational exposure and either RA or AS.
CONCLUSION
Our MR analysis did not establish a direct causal relationship between certain occupational exposures and either RA or AS.

Review
PURPOSE OF REVIEW
There is a well established association between silica inhalational exposure and autoimmune disease, particularly in the context of intense exposure. We will provide in this article an update overview of new sources of silica dust exposure, with evidences of mechanisms from human and animal studies for association between silica and autoimmune diseases, their early detection of silicosis and new options for treatment.
RECENT FINDINGS
New industries such as jewelry polishing, denim jean production, fabrication of artificial stone benchtops, glass manufacturing and glassware has led to re-emergence of silicosis around the world. Silicosis with long term exposure to dust containing crystalline silica has been examined as a possible risk factor with respect to several autoimmune diseases as scleroderma, rheumatoid arthritis, lupus erythematosus, and some types of small vessel vasculitis with renal involvement. The dust may act to promote or accelerate disease development, requiring some other factors to break immune tolerance or initiate autoimmunity. Autophagy, apoptosis, or pyroptosis-related signaling pathways have also been suggested to contribute to the formation of those pathways with coordination of environmental co-exposure that can magnify autoimmune vulnerability.
SUMMARY
Better understanding the mechanisms that involve silica -induced autoimmune diseases may contribute to early diagnosis.

BMJ (Clinical Research Ed.) Aug 2023To evaluate the effect of protracted low dose, low dose rate exposure to ionising radiation on the risk of cancer.
OBJECTIVE
To evaluate the effect of protracted low dose, low dose rate exposure to ionising radiation on the risk of cancer.
DESIGN
Multinational cohort study.
SETTING
Cohorts of workers in the nuclear industry in France, the UK, and the US included in a major update to the International Nuclear Workers Study (INWORKS).
PARTICIPANTS
309 932 workers with individual monitoring data for external exposure to ionising radiation and a total follow-up of 10.7 million person years.
MAIN OUTCOME MEASURES
Estimates of excess relative rate per gray (Gy) of radiation dose for mortality from cancer.
RESULTS
The study included 103 553 deaths, of which 28 089 were due to solid cancers. The estimated rate of mortality due to solid cancer increased with cumulative dose by 52% (90% confidence interval 27% to 77%) per Gy, lagged by 10 years. Restricting the analysis to the low cumulative dose range (0-100 mGy) approximately doubled the estimate of association (and increased the width of its confidence interval), as did restricting the analysis to workers hired in the more recent years of operations when estimates of occupational external penetrating radiation dose were recorded more accurately. Exclusion of deaths from lung cancer and pleural cancer had a modest effect on the estimated magnitude of association, providing indirect evidence that the association was not substantially confounded by smoking or occupational exposure to asbestos.
CONCLUSIONS
This major update to INWORKS provides a direct estimate of the association between protracted low dose exposure to ionising radiation and solid cancer mortality based on some of the world's most informative cohorts of radiation workers. The summary estimate of excess relative rate solid cancer mortality per Gy is larger than estimates currently informing radiation protection, and some evidence suggests a steeper slope for the dose-response association in the low dose range than over the full dose range. These results can help to strengthen radiation protection, especially for low dose exposures that are of primary interest in contemporary medical, occupational, and environmental settings.

Review
PURPOSE OF REVIEW
To describe recent findings in endotyping occupational asthma by addressing the role of specific biomarkers.
RECENT FINDINGS
Studies on occupational asthma endotypes have focused on immune and inflammatory patterns associated with different occupational exposures to sensitizers or irritants.Sputum neutrophilia has been found in 58.5% patients with occupational asthma caused by high molecular weight (HMW) agents, and work-related dysphonia in patients with occupational asthma was described as associated with sputum neutrophilia too. Neutrophils have been associated also with irritant-induced asthma. The measurement of specific IgE has been confirmed as a valuable diagnostic tool in occupational asthma caused by HMW agents, on the contrary, for most low-molecular-weight agents, the presence of specific IgE has been proven in a small subset of affected workers. Fractional exhaled nitric oxide has been confirmed as a marker of type 2 (T2) inflammation in occupational asthma, mostly when induced by HMW agents (e.g. flour), and it has proved to be more sensitive than spirometry in measuring the efficacy of an intervention.MicroRNA-155 has been shown to contribute to airway inflammation in occupational asthma induced by toluene diisocyanate.
SUMMARY
Occupational asthma is heterogeneous, thus monitoring multiple biomarkers is crucial to understand, which inflammatory responses are prevalent.

The majority of Danish women are working, and many are standing/walking or lifting heavy objects at work. It is important for employers and employees to assess ergonomic risk factors in the work environment during pregnancy to avoid potential negative effects on the pregnancy. Studies show that walking/standing > 3-4 h/d may increase the risk of preterm delivery. It is difficult to set specific limits due to heterogenous exposures regarding heavy lifting. Though, results suggest that women should avoid lifting >10 kg repeatedly at work during pregnancy to avoid adverse effects of the pregnancy.

BACKGROUND
Occupational exposure is of increasing concern, posing a serious threat to nurses, especially in the event of a public health emergency. Bibliometrics sheds novel light on the current state of research and factors influencing nurses' occupational exposures, illuminating hot topics and trends in the literature. Bibliometrics is essential to analyze the potential harm to nurses in Asia.
METHODS
Data were extracted from the Web of Science Core Collection on August 6, 2022 with the following search terms: TS= (nurses) AND (TS= (occupational exposure OR occupational health)). CiteSpace and VOSviewer were used to analyze national and institutional collaborations, reference clustering, citations and co-citations of journals and keyword bursts, and HistCite was used to analyze the citation historiography map. To analyze the data and generate statistical charts, Origin and Microsoft Excel were utilized.
RESULTS
A total of 1448 studies on nurses' occupational exposure in Asia were identified. China Medical University had the most publications among Asian institutions, and China had the largest share among Asian countries. Most articles on nurses' occupational exposure in Asia were in the , and the journal with the highest impact factor was the . The COVID-19 outbreak caused a substantial shift in the direction of studies on nurses' occupational exposure in Asia. Mental health is a current hot topic, while sharps injuries and bodily fluid exposure are long-term priorities for attention.
CONCLUSIONS
The hotspots of research on nurses' occupational exposure in Asia focus on mental health, burnout, blood exposure, infection, and sharps injury. Due to the COVID-19 pandemic, recent research has concentrated on personalized mental health care and the development of protective equipment, and cross-disciplinary collaboration may be a new trend in the future.
