Background: Medical emergencies and on-going medical conditions on board may seriously impair seafarers' health and safety, and also negatively impact on future work prospects for seafarers. When a seafarer gets ill or injured on a ship, medical treatment often relies on the competences on his colleagues on board. The aim of this project was to establish a consensus-based minimum standard for medical education for seafarers, in order to ensure competency for adequate management of ill-health on board.

Materials and methods: International Maritime Health Foundation (IMHF) conducted a workshop on medical training of seafarers. A research-based approach to gain consensus on core learning outcomes/competences developed by the Tuning Project, has been used. This method was used by Tuning (Medicine) to gain consensus on core learning outcomes for primary medical degrees (Master of Medicine) across Europe.

Results: The result of the project is a set of learning outcomes/competences in medical training for merchant seafarers.

Conclusions: The project resulted in a set of learning outcomes/competences on medical training of the seafarers that will be submitted to the relevant bodies of International Maritime Organization (IMO) in the process of the development of model courses 1.13, 1.14 and 1.15.

This study aims to analyse safety management in the shipping industry and suggest further research. Safety management is a critical component in preventing accidents within the shipping industry. Unfortunately, ship accidents are relatively common. To improve safety management in the shipping industry, it is necessary to identify various problems and solutions from previous studies. This study uses comprehensive mapping, utilising bibliometric and systematic reviews, to analyse 669 articles within the Scopus database. The findings indicate an increase in the number of publications, while the number of citations is decreasing. China is identified as the most influential country in terms of publication numbers and international collaborations. Co-authorship analysis reveals that only 24 out of 1,773 authors collaborated with other authors. Based on the systematic review, this study concludes that the human factor plays a crucial role in the effectiveness of safety management. Therefore, further research focusing on support systems that can reduce human error in safety management is important. Additionally, research on the relationship between cultural and structural aspects in safety management is necessary to reduce friction between the two aspects. This research contributes to the mapping of previous research and can be used to determine the topic of further research.

Background: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) outbreaks on cruise ships have rarely been investigated. In early 2022, we were informed about a SARS-CoV-2 outbreak on a cruise ship calling Port of Hamburg after 10 infections among crew members were detected. We conducted an outbreak investigation in collaboration between ship owners, the ship physician and Hamburg's Institute for Hygiene and Environment, to identify risk factors and to achieve containment. The aim was to identify risk factors for SARS-CoV-2 infection and SARS-CoV-2 variants in a cohort of 165 crew members.

Materials and methods: For this purpose, we collected data on age, sex, nationality, boarding-time, cabin use (single/shared), work place, and vaccination status of the study participants. Cases were defined as individuals who tested SARS-CoV-2 positive at least once in daily screenings during the outbreak period (10 days) by polymerase chain reaction or antigen test. We investigated risk factors for infection by descriptive, univariable and multivariable analysis. We performed whole genome sequencing to identify SARS-CoV-2 variants.

Results: We verified 103 SARS-CoV-2 positive cases (attack rate [AR] 62.4%); 39/41 sequenced samples were BA.2.3 Omicron subtype, one BA.1 and one BA.1.1. Among boostered crew members, AR was 38% vs. 65% among those vaccinated once or twice. Among those who stayed < 30 days on board, AR was 31% vs. 72% among those staying on board longer. Among Europeans, the AR was 53% vs. 71% in non- -Europeans. Adjusting for age and sex, cases were more likely to have received no booster vaccine (odds ratio [OR]: 2.66, 95% confidence interval [CI]: 0.99-7.13), to have spent more time on board (≥ 30 days, OR: 6.36, 95% CI: 2.81-14.40 vs. < 30 days) and to have a non-European nationality (OR: 2.14, 95% CI: 1.08-4.27). The outbreak stopped shortly after offboard isolation of cases.

Conclusions: This investigation confirms the importance of a booster vaccine against COVID-19. Longer stays onboard could facilitate social mixing. Further studies could investigate the impact of social, cultural/ behavioural patterns and public health access on the infection risk. Physical distancing together with screening and isolation can contain SARS-CoV-2 outbreaks on cruise ships.

Background: Cerebral stroke is the third leading cause of death after cardiovascular disease, cancer and the leading cause of disability for patients. Hyperbaric oxygen is a non-drug treatment that has the potential to improve brain function for patients with ischaemic stroke. The objective of this study was to evaluate the results of treatment of acute cerebral infarction with hyperbaric oxygen therapy (HBOT).

Materials and methods: This was a case-control study. One hundred ninety-five patients diagnosed with cerebral infarction, with signs of onset within 24 hours, were treated at the Centre for Underwater Medicine and Hyperbaric Oxygen of Vietnam National Institute of Maritime Medicine during the period from January 2020 to December 2022. Study group included 100 patients with acute cerebral infarction treated with a combination of HBOT and medication and reference group included 95 patients treated by medication only (antiplatelets drugs, statins, control of associated risks factors) RESULTS: After 7 days of treatment with hyperbaric oxygen (HBO), symptoms such as headache, dizziness, nausea, sensory disturbances, and Glasgow score of the study group improved better than that of the reference group (p < 0.01). Movement recovery in the study group was better than the reference group: the percentage of patients with mild and moderate paralysis in the study group increased higher than that of the reference group (86.0% and 68.4%), the degree of complete paralysis of the study group decreased more than that of the reference group (14.0% and 31.6%). The degree of independence in daily activities in the study group was better than the reference group. In the study group, the percentage of patients with complete independence in daily life increased from 27.0% to 84.0%. In the reference group, the rate of patients who were independent in their daily activities increased from 37.9% to 51.6%. The average number of treatment days of the study group was 10.32 ± 2.41 days and it the reference group 14.51 ± 3.24 days.

Conclusions: Hyperbaric oxygen therapy is a non-drug treatment with many good effects in the treatment of cerebral infarction, especially acute cerebral infarction. HBOT reduces and improves functional symptoms, improves mobility, and reduces treatment time for patients.

Background: Poland has experienced increased economic migration since 2021. Large waves of migrants, mostly from Asian and African countries, are trying to get into the European Union by crossing Poland's eastern border illegally. The influx of illegal migrants into Poland is the result of a policy adopted by the Belarusian and Russian regimes that are trying to provoke another migrant crisis in Europe. In the opinion of some Polish politicians illegal migration contributes to the spread of parasitic diseases in our country as many migrants arriving into Poland carry intestinal parasites. The aim of this study was to assess the prevalence of infections with intestinal parasites in the Polish Border Guard officers safeguarding Poland's eastern borders.

Materials and methods: Parasitological diagnostics was carried out between April and May 2023. The study involved 218 Polish Border Guard officers from the Podlaski Border Guard Unit (PBGU) and 209 officers from the Bug Border Guard Unit (BBGU), whose task is to patrol and safeguard Poland's border with Ukraine and Belarus. Faecal examinations were performed using three different light microscopy testing methods (direct smear, decantation, flotation) at the Department of Epidemiology and Tropical Medicine at the Military Institute of Medicine - National Research Institute, Warsaw, Poland.

Results: Considered to be potentially pathogenic intestinal parasites were diagnosed in 20 out of 218 officers serving in the PBGU (8.7% infected with Blastocystis spp., 0.5% with Dientamoeba fragilis) and in 9 out of 209 officers serving in the BBGU (3.8% infected with Blastocystis spp., 0.5% with Dientamoeba fragilis). There were no infections with nematodes, cestodes or trematodes in the study participants. No correlation was found between a parasitic infection and the presence of diarrhoea or other gastrointestinal symptoms within 6 months prior to the study in both groups.

Conclusions: Although Polish Border Guard officers deployed to the eastern border are exposed to difficult environmental conditions and have frequent contacts (either directly or indirectly) with migrants arriving from countries which report high incidence of parasitic infections, the rates of infections with potentially pathogenic protozoa in officers from the PBGU and BBGU are low and mainly attributable to pathogens which are widespread in the general Polish population. Low rates of parasitic infections in officers serving in the border zone suggest that the epidemiological situation of parasitic diseases in East Poland is satisfactory and that the disease prevention strategies (including the use of personal protection gear) implemented by the Polish medical services are effective.

Scuba diving is an activity that people engage in both for recreational purposes as well as having professional, commercial, and military applications. Scuba diving has often been considered a high-risk activity but, overall, scuba diving has been shown to be a safe activity when divers participate within their experiential, physical, and psychological limits. However, increased physical and psychological stress can quickly arise during diving activities due to unexpected events and situations and may lead to the onset of panic in an unprepared diver. Dive safety is dependent on the ability of a diver to understand the primary signs of stress and panic and attempt to minimise their potential impacts on the immediate situation. The purpose of this review is to examine the stress response in divers, illustrate the role that panic plays in potential diving accidents and fatalities, and provide recommendations to both help understand and manage stress and panic in the diving community in an effort to further increase the overall safety of scuba diving across all applications.

Background: Marine engineering is a profession that affects a high level of physical and psychological stress. Such a high level of stress was further aggravated during the coronavirus disease 2019 (COVID-19) pandemic. On the other hand, personality traits and perceived stress are linked with each other, while job ranks also influence stress levels among employees. However, very few clinical studies are available on this mechanism in seafarers. This study explores the hidden area through the collection of cross-sectional data.

Materials and methods: Big Five personality traits instrument, along with a stress augmentation questionnaire, were administered among 280 Indian marine engineers across job ranks who have sailed prior to and during the COVID-19 pandemic. The collected data were analysed using Kruskal-Wallis test and structural equation modelling.

Results and conclusions: The analysis reveals significant differences among Indian marine engineers across their job ranks towards their perception of augmented stress levels. It also indicates that, except for extraversion, personality traits have linkages with levels of augmented stress among Indian marine engineers during the pandemic.
