“…The metabolic pathways related to these studies include fat-soluble intermediate metabolites. Alternatively, the current study analyzed only hydrophilic metabolites, which may explain the few overlaps in altered metabolites between our data and the above-mentioned studies [ 34 , 35 , 36 , 37 , 38 , 39 ].…”

“…No metabolomic study has analyzed the relationship between urinary metabolites and mental health in JARE. However, various teams have investigated the relationship between mental illnesses and metabolic changes in the Antarctic area [ 34 , 35 ]. For example, metabolism related to bone-mass density is disturbed by vitamin D deficiency caused by limited ultraviolet light exposure [ 36 , 37 ].…”

Antarctic expeditions have a high risk of participant depression owing to long stays and isolated environments. By quantifying the stress state and changes in biomolecules over time before the onset of depressive symptoms, predictive markers of depression can be explored. Here, we evaluated the psychological changes in 30 participants in the Japanese Antarctic Research Expedition using the Patient Health Questionnaire-9 (PHQ-9). Urinary samples were collected every three months for a year, and comprehensive urinary metabolomic profiles were quantified using liquid chromatography time-of-flight mass spectrometry. Five participants showed major depressive episodes (PHQ-9 ≥ 10) at 12 months. The urinary metabolites between these participants and the 25 unaffected participants were compared at individual metabolite and pathway levels. The individual comparisons showed the most significant differences at 12 months in 14 metabolites, including ornithine and beta-alanine. Data from shorter stays showed less significant differences. In contrast, pathway and enrichment analyses showed the most significant difference at three months and a less significant difference at longer stays. These time transitions of urinary metabolites could help in the development of urinary biomarkers to detect subjects with depressive episodes at an early stage.

Professional activities in the extreme conditions of Antarctica and the Arctic are primarily associated with major risks to life and health, including psychological risks, for the personnel of polar stations. The relevance of this study is driven by the fact that in extreme forms of professional activity, such as expeditions to the Earth’s poles, extreme sports, military operations, etc., one of the main criteria for selecting and forming effective and cohesive teams or groups is understanding the primary motives behind their actions. Motivated individuals tend to perform better and achieve greater success. The purpose of the study is to identify the leading motivations for professional activity in extreme conditions among winterers of Ukrainian Antarctic expeditions across different age groups. To achieve this purpose, methods of theoretical and empirical analysis, observation, generalisation, and systematisation of age groups were chosen. The paper defines and establishes an age-based classification of participants in annual expeditions to the Ukrainian Antarctic station “Academic Vernadsky”. Through surveys, the study measures the level of motivation among individuals towards professional activities in Antarctica within three age groups: younger, middle-aged, and older. Three leading motives are identified: spiritual, social, and material. The analysis of the obtained data concerning the level of these leading motivational factors in polar station environments provides insights into the main reasons driving motivation for prolonged professional activity and helps in adapting to the extreme conditions of the surrounding environment. In addition, age-related differences in motivational processes among different age groups of winterers are presented, allowing for the formation of well-coordinated teams of polar expedition participants of varying age categories. The findings can be used in planning activities in long-term polar expeditions, in military and sports psychology.
