Maritime activities are increasing in the Arctic and near Arctic areas, including domestic shipping and international transit traffic. Arctic shipping has created opportunities for cruise tourism, resource transportation, community supply transportation, research, and government services. However, hazards and challenges inherent to maritime operations in the Canadian Arctic cannot be ignored, including extreme Arctic weather conditions, limited port infrastructure, extensive distances from search and rescue services, and restricted access to medical care in Northern communities. The onset of the COVID-19 pandemic has compounded these challenges, posing a threat to the well-being and safety of seafarers.This chapter explores the occupational health and safety challenges confronted by Canadian Arctic seafarers during the COVID-19 pandemic through qualitative interviews with 20 industry stakeholders, including seafarers, union representatives, managers, and maritime consultants. The findings revealed seafarers’ concerns of increased risks due to pandemic-induced public health measures including lockdowns, travel restrictions, and controls. The deprivation of shore leaves and prolonged isolation from families substantially impacted the mental health of seafarers, amplifying the risks of depression and anxiety. A comprehensive Arctic occupational health and safety (OHS) policy framework is recommended to support seafarers in addressing the above challenges.

Introduction: Noise is a significant health hazard for fish harvesters. Chronic exposure to hazardous noise levels of 85 dB (A) for an 8-h work shift can have adverse health impacts, including both auditory and non-auditory health problems such as noise-induced hearing loss, stress, hypertension, sleeping disorders, and impaired cognitive performance.Methods: A review of legislation and policies governing workplace noise exposure, as well as qualitative, semi-structured interviews, were conducted to assess how fish harvesters in Newfoundland and Labrador (NL) manage onboard occupational noise exposure and perceive noise-induced health problems, as well as the barriers and challenges associated with preventing and controlling noise exposure.Results: The legal review shows no compulsory noise preventive measure at the fishing vessel design stage in Canada. Limited implementation of Occupational Health and Safety (OHS) regulations to control and prevent onboard noise by employers in Newfoundland and Labrador. Fishers reported that their workplace is noisy. Over time, fish harvesters adapted to the environment and learned to tolerate loud noise, displaying fatalistic behavior. Fish harvesters reported avoiding using hearing protection onboard due to navigation safety concerns. Fishers reported hearing loss as well as other non-auditory health problems. Inadequate noise control measures adopted by employers, a limited supply of hearing protection onboard, and a lack of regular hearing testing, training, and education were identified as the main barriers to preventing and controlling noise exposure.Conclusion: Proper implementation of NL OHS regulations and the development of hearing conservation initiatives by employers are necessary. All stakeholders, including the federal and provincial governments, WorkplaceNL, and not-for-profit fishing organizations in the province, are strongly recommended to initiate training and education campaigns to help fish harvesters understand noise exposure and adopt preventive measures.

Background: Occupational noise exposure has been identified as a significant risk factor for fish harvesters. Chronic noise exposure causes hearing and other health problems and undermines the quality of life and well-being. This review paper aims to highlight noise-related auditory and non-auditory health effects among fish harvesters. Materials and methods:A systematic literature search approach was adopted using the following databases: PubMed, Embase, SCOPUS, Web of Science, Google Scholar, and by exploring grey literature. The literature search was conducted in 2020 (between October 15 and November 30). Relevant articles were explored by reviewing title, keywords, and abstract based on the inclusion and exclusion criteria. The full-text critical review of selected papers was made and finalized the most relevant studies. Results: Initial 1,281 records were identified, exploring various databases and additional sources using relevant keywords. Duplicate articles were removed and retrieved 746 articles. After that, a screening of 746 research papers was done based on the selection criteria and finalised 28 articles for full-text review. Finally, articles were filtered based on the study's aim and extracted 17 papers for the final review. Conclusions: Noise-induced hearing loss was considered a significant health risk to fish harvesters across the studies, affecting physical and emotional well-being. The prevalence of hearing loss was observed from 6% to 80%. Other health problems, such as headache, dizziness, annoyance, stress, fatigue, elevated blood pressure, sleep disturbances, and impaired cognitive performance, were also reported. Further research is needed to validate the non-auditory health effects among fish harvesters.

Benign Mucous Membrane Pemphigoid (MMP) is a vesiculobullous (VB) lesion that affects oral and nasal mucosa, oropharynx, conjunctiva, and genital mucosa. It is considered an autoimmune disease. Autoantibodies are produced due to several external factors or genetic factors. It creates many complications, such as defects in vision, voice alteration (hoarseness), airway obstruction, and dyspareunia. The subepithelial blisters form due to these antibodies. Treatment modalities differ from topical steroids to systemic steroid therapy based on the nature and severity of clinical symptoms.

Introduction: Healthcare professionals including surgeons, dentists and paramedical personnel’s belong to high risk group of transmitting blood borne pathogens. Keeping this in view a study was proposed to assess the Knowledge, Attitude, and Practices (KAP) of dental professionals towards different viral diseases in northeast part of Rajasthan. Materials and Method: A cross-sectional, descriptive study was conducted among 500 randomly selected dentists in Jaipur district. Questions regarding KAP of hepatitis B (HBV), Hepatitis C (HCV) and Human immunodeficiency virus (HIV) / Acquired immunodeficiency syndrome (AIDS) were included in the questionnaire. Statistical analysis was done through SPSS Ver. 20.0. software using chi-square test, independent t-test and analysis of variance (ANOVA) to evaluate the differences between parameters. Results: The result indicates that the majority of the study subjects (60%) were female. The mean (+Standard Deviation) for age and work experience was 35.5+8.85 and 5.6+8.76 respectively. The mean value of KAP was 38.4+3.23, 21.5+4.34 and 23.05+5.67 respectively. It was observed that knowledge regarding HBV, HCV and HIV/AIDS was statistically significant with work experience (>10 Years; p<0.001), year of graduation (after 2006; p<0.001). Attitude of study subjects for HBV, HCV and HIV/AIDS was significantly inclined by age group (< 30 years: P = 0.011), work experience (≥10 years: P < 0.001), and place of work (dental clinic: P = 0.013). Conclusions: The observations of the study highlighted a reasonable level of knowledge and attitude of dental practitioners for HBV, HCV and HIV/AIDS infections. However there is a need of improvement in the knowledge level which can alter their attitude and practice towards patients with HBV, HCV and HIV/AIDS infections

INTRODUCTION: Surgical extraction of third molar irrespective of any technique results in postoperative pain, swelling of face and limited mouth opening. The aim of the present study was to assess and compare the effects of Dexamethasone (4mg) administered prior to surgery.MATERIALS AND METHOD: A randomized control trial was conducted which included a total of fifty patients. All the patients were randomly put in two groups of twenty five each. Group I patients underwent transalveolar extraction of third molar under local anesthesia and standard oral drug regime. Group II patients received an additional submucosal injection of dexamethasone 4 mg, thirty minutes prior administration of local anaesthesia. Pain, swelling and mouth opening was recorded on second, seventh and tenth post-operative days after surgery.RESULTS: The difference in pain scores on second post-operative day between two groups were found statistically non-significant. However, there was significant reduction in pain scores on seventh and tenth day in both groups. Mouth opening showed statistically significant difference between the two groups.CONCLUSION: The observations of the present study provide a fundamental basis for the use of corticosteroids such as dexamethasone sodium phosphate in the form of submucosal administration in lower than usual doses to decrease postoperative inflammation when compare to other routes of drug administration.

Background: Professional and paramedical students have a key role in oral health promotion. The aim of this study was to assess oral health–related Knowledge, Attitude, and Practice (KAP) among the nursing students in Rajasthan. Materials and Methods: A cross-sectional, questionnaire-based study was carried out among 409 nursing students from five different institutes who were selected by simple random sampling. A 27-item questionnaire was used to assess KAP. The resulting data were analyzed using frequency distribution. Results: Over 50% of the students used toothbrush and toothpaste twice a day to maintain their oral hygiene. Besides, 41% recognized the importance of dental visit in case of gingival bleeding and knew that poor oral hygiene is responsible for bad breath. Conclusions: Oral health–related behavior among the nursing students needs improvement. More educational and preventive programs should be organized to achieve better results.
