The article focuses on popular extreme sports, common risk factors associated with extreme activities as well as the recommended prophylaxis and precautionary measures.Every seafarer undergoes a medical examination prior to joining a ship. Some disorders cannot be detected and they may appear while at sea. Diagnosing and managing them becomes extremely difficult for the Master being the caregiver on board. https://www.selleckchem.com/products/VX-770.html Large crude carriers often perform long voyages and due to their sheer size, do not enter any port. Helicopter evacuation of a sick or injured crew is the norm. They operate under strict chartering time lines which do not permit deviation from course. A case of hemiparesis on left side of body in a young hitherto healthy seafarer which was later diagnosed as a case of neurocysticercosis is described.Long and irregular shifts, unforeseeable operations and high responsibility are still prominent in the job of a pilot and pose high psycho-physical demands. Furthermore, there is a disturbed work-family balance. Working hours of pilots are highly variable and not bound by regulations due to irregularities of vessel traffic. The pilots have to work in a shifting rotation system. This paper demonstrates the stressors during their work routine and shows the usual working profile of a pilot during their service.
Over the decades, several published studies showing the relevance of alcohol use among seafarers/fishermen have highlighted the dangers of alcohol consumption during working time. The present study aims to provide an up-to-date overview of the prevalence of alcohol consumption among seafarers/fishermen. It also points out their consumption behaviour, depending on socio-demographic and job-related factors.

To detect relevant studies for this systematic review, the electronic database PubMed was searched. All identified studies published between January 2014 and September 2019 were included using the subsequent terms (alcohol OR ethanol) AND (seafarer OR fishermen OR ship crew OR merchant ship).

According to the applied search string, 18 studies were identified. Thirteen of them were selected for this review. The results of the studies about alcohol consumption among seafarers and fishermen showed a wide range of prevalence, from 11.5% to 89.5% (median 53.0%). Concerning seafarers no stratified data were factors.
The consumption of alcohol among fishermen has declined over time. Compared with the landbased European population, seafarers and fishermen show a lower prevalence of alcohol use, at least during their stay on board. Due to the limited data available - especially concerning seafarers - further studies on the prevalence of alcohol consumption among shipboard crews are recommended. In particular, these should provide more data on alcohol consumption related to socio-demographic and job-related factors.COVID-19 is a global disease that has quickly shaken the world economy since the beginning of 2020 and consequently has significantly affected the shipping industries development (including shipping operators, port operators, government authorities, shippers, seafarers, passengers, supply chain operators, etc.). Currently, the clinical management of COVID-19 remains unclear. In order to understand the newest challenges and figure out potential solutions for the maritime industries post COVID-19, this paper selected four shipping industries (including dry bulk, tanker, container, and cruiser sector) and reviewed these industries' newest development. The research findings can strengthen the awareness of COVID-19 and reduce operational risk and further improve business performance for the maritime related industries and authorities.
Sea sickness is the type of motion sickness induced by maritime transport. Its prevention through optokinetic exercises is efficient. The object of this study is to evaluate the efficiency experienced by the patients as well as the impact on other motion sicknesses.

One hundred and forty-one patients underwent optokinetic treatment methods between 2006 and 2014. The following parameters were studied and scored on a numeric scale sea sickness, intensity of vomiting and ability to hold position and duties on board.

Study parameters significantly improved by optokinetic reeducation method. Sea sickness was reduced by a factor of 2. Study settings were also stable over years. Other motion sicknesses were also improved with this optokinetic stimulation.

Treating sea sickness by optokinetic stimulation reeducation gives good results particularly improving its related clinical manifestations, therefore allowing seamen to properly hold their functions on board. Its efficiency lasts in time and seems promising for the management of other motion sicknesses.

The high number of marine incidents in port and coastal areas due to the tired deck officers' erroneous actions are one of the major challenges of marine transportation. Approaching, berthing, and cargo handling (ABC) are the most stressful and exhausting operations of the ship in these areas, which are carried out consecutively and uninterruptedly.

This study examined Psychomotor Vigilance Task (PVT) performance, Arrow Flanker Task performance and the Pittsburgh Sleep Quality Index (PSQI) of 70 deck officers of ocean-going oil tankers with 4on-8off shifts at the end of the first shift of cargo-handling operations. In this case, they had worked more than 14 hours continuously. Also, their level of sleepiness was assessed using the Karolinska Sleepiness Scale (KSS) at the beginning, middle, and end of their first shift of handling operation.

The results were analysed according to the duration at sea and deck officers rank. PSQI, KSS, PVT mean reaction times and lapses, and also Flanker's variables were higher among the chief and second officers who were present on board between 0-30 days. The state of officers who were present on board between 31 to 60 days was better than the officers with 0-30 and 61-90 days' duration at sea. In addition, the results show that sleep quality during tour of duty affects cognitive performance and sleepiness of officers during cargo handling operations.

The paper concludes by discussing possible solutions for reducing fatigue and human error among seafarers.
