[PMID: 37851694 PMCID: PMC10584167 DOI: 10.1371/journal.pone.0293118] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/10/2022] [Accepted: 10/05/2023] [Indexed: 10/20/2023] Open
Abstract
OBJECTIVES The aim of this study is to provide an updated overview of the oral health status and associated risk factors in maritime settings. METHODS We systematically searched PubMed, Ovid Embase, Web of Science, CINAHL and SCOPUS from January 2010 to April 2023. Two independent reviewers extracted the data. The quality of included studies was assessed using relevant assessment tools. RESULTS A total of 260 records were found in the initial search; 24 articles met the inclusion criteria. Most studies had descriptive design, and only two randomized controlled trials were found. The main oral health issues noted are oral cancer, dental caries, periodontal diseases, oral mucosal lesions, and dental emergency. Male seafarers have higher risk of oral cancers in the tongue, lips, and oral cavity while oral mucosal lesions are more prevalent among fishermen. CONCLUSIONS Dental caries and periodontal diseases are prevalent in both seafarers and fishermen. The consumption of tobacco, alcohol, fermentable carbohydrate, and poor oral hygiene are risk factors that affect the oral health status at sea. The occurrence of oral diseases in maritime setting requires more attention of researchers and authorities to develop strategies to tackle these issues. TRIAL REGISTRATION Systematic review registration number in PROSPERO: CRD42020168692.

Hsu JL, Liao MF, Chu CC, Kuo HC, Lyu RK, Chang HS, Chen CM, Wu YR, Chang KH, Weng YC, Chang CW, Chiang HI, Cheng CK, Lee PW, Huang CC, Ro LS. Reappraisal of the incidence, various types and risk factors of malignancies in patients with dermatomyositis and polymyositis in Taiwan. Sci Rep 2021; 11:4545. [PMID: 33633147 PMCID: PMC7907377 DOI: 10.1038/s41598-021-83729-5] [Citation(s) in RCA: 18] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2020] [Accepted: 01/14/2021] [Indexed: 12/13/2022] Open
Abstract
Our study aimed to investigate the incidence, risk factors and time to occurrence of malignancy in patients with dermatomyositis (DM) and polymyositis (PM). The electronic medical records of 1100 patients with DM and 1164 patients with PM were studied between January 2001 and May 2019. Malignancies after myositis were diagnosed in 61 (5.55%) patients with DM and 38 (3.26%) patients with PM. The cumulative incidence of malignancies in patients with DM were significantly higher than patients with PM (hazard ratio = 1.78, log-rank p = 0.004). Patients with DM had a greater risk of developing malignancy than those with PM at 40–59 years old (p = 0.01). Most malignancies occurred within 1 year after the initial diagnosis of DM (n = 35; 57.38%). Nasopharyngeal cancer (NPC) was the most common type of malignancy in patients with DM (22.95%), followed by lung, and breast cancers. In patients with PM, colorectal, lung and hepatic malignancies were the top three types of malignancy. The risk factors for malignancy included old age (≥ 45 years old) and low serum levels of creatine phosphokinase (CPK) for patients with DM and male sex and low serum levels of CPK for patients with PM. Low serum levels of CPK in patients with myositis with malignancy represented a low degree of muscle destruction/inflammation, which might be attributed to activation of the PD-L1 pathway by tumor cells, thus inducing T-cell dysfunction mediating immune responses in myofibers. A treatment and follow-up algorithm should explore the occurrence of malignancy in different tissues and organs and suggested annual follow-ups for at least 5.5 years to cover the 80% cumulative incidence of malignancy in patients with DM and PM.

Yang CY. Deaths from colon cancer among farmers in Taiwan: a mortality odds ratio study. JOURNAL OF TOXICOLOGY AND ENVIRONMENTAL HEALTH. PART A 2019; 82:1137-1142. [PMID: 31826720 DOI: 10.1080/15287394.2019.1702312] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Indexed: 06/10/2023]
Abstract
Few studies have examined the association between increased risk of colon cancer development and occupation of farming. Data thus far have been inconsistent with respect to a correlation between farming and colon cancer occurrence. This type of study has not been undertaken in Asia. The aim of this investigation was to utilize the mortality odds ratio (MOR) design to estimate the relative risk (RR) of mortality attributed to colon cancer in farmers in Taiwan. Utilizing Taiwan's Death Certificate Registry, data were collected on subjects who died between 1997-2009. Our study group was comprised of individuals 50 years of age and higher who died of colon cancer, while the control group consisted of subjects the same age who died of all other causes excluding cancers. Multiple logistic regression was performed to compute the MOR adjusted for gender, age at death, year of death, marital status, and urbanization levels. Of the 32,456 farmers who died, 558 were attributed to die of colon cancer. Farmers in Taiwan had a significantly lower risk of mortality from colon cancer than non-farmers (MOR = 0.85, 95% CI = 0.78-0.93), similar to estimates reported in previous meta-analyses. Occupational physical activity or higher consumption of vegetables and fruits might have contributed to the lower risk of death due to colon cancer. The basis for these observations requires further examination as it appears that lifestyle is a crucial factor in colon cancer development.

[PMID: 31620368 PMCID: PMC6760027 DOI: 10.3389/fonc.2019.00911] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/05/2019] [Accepted: 09/02/2019] [Indexed: 01/12/2023] Open
Abstract
The incidence and mortality of oral squamous cell carcinoma (OSCC) are high, and the number of oral cancers had risen in the world. However, chemotherapy drugs have numerous side effects. There is an urgent requirement to develop a novel drug that can be used to treat oral cancer. Hydroxygenkwanin (HGK) is a nature flavonoid extracted from Daphne genkwa Sieb. et Zucc. (Thymelaeaceae). Previous studies had demonstrated that HGK exhibits anticancer effect, but the effect is still unclear in oral cancer. HGK inhibited cell growth dose-dependently in SAS and OCEM1 cells. The functional enrichment analysis showed the significant pathway in cellular movement, cell cycle and cellular growth and proliferation. We further demonstrated the HGK induced the cell cycle arrest by flow cytometry and inhibited colony formation ability and cell movement. The western blot showed that HGK induced cell cycle arrest through p21 activation and caused intrinsic cell apoptosis pathway. HGK inhibited the cell invasion and migration through down-regulation vimentin. HGK might be an effective natural product for oral cancer therapy.
