TL;DR: In this paper, a plant protein product (FP) was included in the diet of first-year university students to prevent high morbidity, and the effectiveness of this food intervention in preventing the most common diseases among Kaliningrad students was assessed.
Abstract: The Kaliningrad region is known for its specific climate, which can negatively affect the adaptive potential of the body. This manifests in an increased incidence of respiratory diseases and skin conditions. To prevent high morbidity, a plant protein product was included in the diet of first-year university students. This study aimed to assess the effectiveness of this food intervention in preventing the most common diseases among Kaliningrad students. Two groups of university students took part in the food trial. In the control group, catabolic processes prevailed in nutrient metabolism. Disadaptation manifested itself in the metabolism of proteins, vitamins, minerals, hematopoiesis and humoral immunity. Inflammation was indicated by α1- and α2-globulins, a weak immune response, and IgM and IgG. High oxidative stress and low antioxidative ability of blood serum were observed. The plant-based protein product (FP) helped preserve testosterone level and prevent an increase in catabolic reactions. Moreover, it had a positive effect on both red blood cell hematopoiesis (a smaller increase in the average volume of erythrocytes, the same average concentration and content of hemoglobin, an increased relative red cell distribution width (RDW) and white blood cell hematopoiesis (a beneficial effect for the immune system: lymphocytes, the relative content of neutrophils, monocytes, basophils and eosinophils). The stimulation of humoral immunity was evidenced by beta- and gamma-globulins, an active immune response, the level of IgM and IgG, antioxidant protection, reduction of peroxides and an increase in antioxidant activity of blood serum. The 34-week observation showed a 1.7-fold decrease in the incidence of respiratory illnesses and a 5.7-fold decrease in skin and subcutaneous tissue diseases. Acute respiratory infections were reduced 1.8-fold. There were no cases of community-acquired pneumonia in the treatment group, compared with 55.1‰ in the control group. The incidence of respiratory diseases was 3.3-10.6 times lower in the treatment group than in the control group in weeks 6-19. The findings testify to the prophylactic effect of functional food during social adaptation and acclimatization of students.

TL;DR: In this paper, the authors used the Steadman apparent temperature method to analyse the health impact of physical factors and investigated student morbidity in three Kaliningrad universities that had different percentage responses to the local climate change.
Abstract: Student morbidity during adaptation to the weather and climate conditions of the Baltic Sea is evaluated from 2012 to 2017 in this study. The research used the Steadman apparent temperature method to analyse the health impact of physical factors and investigated student morbidity in three Kaliningrad universities that had different percentage responses to the local climate change. Apparent temperatures (T) with different combinations of meteorological parameters significantly deviated from monthly average temperatures. For the average temperature and maximum wind speed, apparent temperatures were found to be negative from September to March. In January and February, they were 7.8–16.8 times lower than the average T. With humidity (e.g., RH) unchanged, different combinations of physical factor posed no danger to a person dressed for the weather conditions. In January, at the minimum T and maximum wind speed (Uh), frostbite was possible after 20–30 of exposure. Apparent T close to the threshold value was observed in December and February. The climate of the Kaliningrad enclave is not the best for human health conditions. In the winter, there are serious risks of frostbite in uncovered parts of the body when threshold conditions were not met. Results suggested that disease susceptibility in non-local students representing all the universities was 1.2–1.7 times higher than these of locals students. Also, a relationship between morbidity and percentage of non-local students is obtained, suggesting that the weather and climate conditions will likely adversely affect human health during climate change adaptation that can likely increase the morbidity rate, particularly among the students.

TL;DR: Determination of individual indices of IL-8 allows using as a prognostic criterion for exacerbation of the epidemiological situation for respiratory diseases.
Abstract: Introduction. Changes in a number of cytokines are shown not only during inflammation: during physical exertion or stress; moderate hypoxia Material and methods. We evaluated the rates of interleukins 6 and 8 and white blood among cadets of a military educational institution during adaptation, dividing into 2 stages: initial, 2 and 3 months of observation, as well as the pre-seasonal - rise-decrease in the incidence of respiratory diseases (4-6 months). By the response of white blood, the state of non-specific adaptive reactions of the body was assessed. Results. When IL-6 level was within normal limits, it increased 1.5 times after 2 months (not significantly), which was probably due to a stress response. During this period, adequate adaptive processes proceeded, confirmed by indices of the absolute content and percentage of lymphocytes characterizing non-specific adaptive responses of the body. The average IL-8 was within normal limits. However, in 9.1% of individuals, it initially exceeded or was at the level of the upper limit of normal; in the pre-season period it increased by 29.1% ((p = 0.042): an increase of 63.6%, of which 42.5% - to the level of the upper limit of the norm or above it. In 30.0%, the leukocytes were above the norm, which proved the infection of the team members. At the peak and with a decrease in the incidence of interleukin, IL-6 increased within normal limits, IL-8 decreased. IL-8 exceeded the norm in patients and individuals after clinical recovery. A group of persons was determined in whom it spent 4-6 months of observation within the upper limit of the norm or exceeded it. Among them were people who did not apply for illness. The second group of individuals with no signs of disease, but with high IL-8 values, was isolated in the pre-season period. Conclusion. An increase within the normal range of IL-6 is not enough to cause acute systemic inflammatory effects. Determination of individual indices of IL-8 allows using as a prognostic criterion for exacerbation of the epidemiological situation for respiratory diseases.

TL;DR: The excess of the upper limit of the annual incidence rate in the same seasons and months of the year proves the role of body resistance in disease pathogenesis.
Abstract: The objective of the study was to analyze disease incidence and prevalence rates among university students in the city of Kaliningrad. Materials and methods. We analyzed morbidity among first to fifth year students of a civil (No. 1) and two military universities (Nos. 2 and 3) including its structure per 1,000, trends, annual incidence and prevalence rates among local and nonresident students. Results and discussion: The overall prevalence rates were higher in the military universities (1,474.9 ± 14.5 % and 930.4 ± 5.2 % in Nos. 2 and 3, respectively) than in the civil one (802.1 ± 10.3 %). In universities Nos. 1 and 3, the prevalence rates of diseases of the skin and subcutaneous tissue were similar while the rates of diseases of the genitourinary system were higher than those in university No. 2. We observed a higher disease prevalence rate among unacclimated students: the smaller was their percentage, the lower was the overall rate. In the universities 1-3 the prevalence rates in local and nonresident students were 779.1 ± 11.8 % and 918.9 ± 17.0 % (p = 0.000), 921.5 ± 13.5 % and 1,548.1 ± 16.9 % (p = 0.000), and 719.5 ± 12.7 % and 906.2 ± 9.6 % (p = 0.000), respectively. The nonresident students of the civil university were healthier: their prevalence rates of diseases of the eye and adnexa, mental and behavioral disorders, and diseases of the musculoskeletal system and connective tissue were, respectively, 2.8, 1.9 and 4.2 times lower than those in non-local students of the military establishments. Conclusions. Respiratory diseases and diseases of the skin and subcutaneous tissue generally prevailed among the students. The excess of the upper limit of the annual incidence rate in the same seasons and months of the year proves the role of body resistance in disease pathogenesis. The observed disease rates were higher in the military universities than in the civil one due to the specific features of nutrition, accommodation, and the educational process (curricula, indoor and outdoor classes at the training ground). The analysis of morbidity rates among students of each year is essential for the development of efficient preventive measures. General measures shall include ways and means of boosting the immune system as well as proper sanitary and hygienic conditions of students' accommodation and learning facilities.

TL;DR: In this article , the most significant factors have been determined based on the analysis of literature data, and significant areas of development of self-preserving technologies for students were determined based upon the obtained data, including examination of morbidity risk factors due to the educational period (from the first to the last educational year), assessing the effect of weather and climate conditions on the educational territory (examining the process of students' acclimatization), determining the role of academic process technologies as a health risk factor (long distance learning technologies, certain educational program), examining the progression and technology optimizing students’ way of life at different stages of education, assessment of physical activity, influence on accessibility of educational programs, significance of using electronic devices and educational means, feeding trends (ethnic ones, conditions and possibilities of adherence to the principles of healthy nutrition), etc.
Abstract: Students belong to a special medical and social group. A risk of health disturbances is typical of this community. It is associated with the influence of various habitat and educational factors. The most significant factors have been determined based on the analysis of literature data. It is about high levels of stress and depression due to low physical activity, high level of psychoemotional stress during lessons and examination periods, irrational and irregular nutrition, social adaptation to a new habitat, which is often accompanied by acclimatization while moving for educational purposes, disorders of sleep and rest, harmful habits. Significant areas of development of self-preserving technologies for students were determined based on the obtained data. They can include as follows: examination of morbidity risk factors due to the educational period (from the first to the last educational year), assessing the effect of weather and climate conditions on the educational territory (examining the process of students’ acclimatization), determining the role (peculiarities) of academic process technologies as a health risk factor (long-distance learning technologies, certain educational program), examining the progression and technology optimizing students’ way of life at different stages of education, assessment of physical activity, influence on accessibility of educational programs, significance of using electronic devices and educational means, feeding trends (ethnic ones, conditions and possibilities of adherence to the principles of healthy nutrition), etc.

TL;DR: In this paper , the authors evaluated the impact of diets with functional foods on health indicators while minimizing the negative impact of adaptation and acclimatization on the body of first-year university students at the start of their studies.
Abstract: Background: The period of rapid transition from school to university is associated with a complex of negative stress factors caused by social and professional adaptation, irregular daily routine, sleep, and nutrition. During this period, the inclusion of functional foods in students’ diets has an increasingly beneficial effect on their health. This study aimed to evaluate the impact of diets with functional foods (vegetable and protein–vegetable) on health indicators while minimizing the negative impact of adaptation and acclimatization on the body of first-year university students at the start of their studies. Materials and Methods: A total of 150 first-year students were randomly selected. Biochemical tests, enzyme immunoassays, and analyses of serum immunoglobulin levels and mineral and vitamin content in first-year students’ blood were performed. Results and discussion: Protein–vegetable products are more potent compared to plant-based ones in increasing the body’s natural resistance to all types of stress due to their high protein content. The other functional product had a higher content of carbohydrates. In addition, they differed in the content of minerals and vitamins. Conclusions: The importance of a rational diet increases exponentially during the period of adaptation and acclimatization when the emotional, mental, and physical workload increases.

TL;DR: Duration of the period of adaptation of military university cadets to conditions of learning is influenced by a synergistic effect of adverse environmental factors, and adaptation of non-resident cadets lasts longer due to acclimatization to weather and climate conditions of the enclave.
Abstract: Introduction . It is relevant to determine periods of adaptation of local and non-resident students coming from other Russian regions to learning conditions. The objective of our study was to measure duration of cadets’ adaptation to the learning environment as assessed by the incidence of respiratory diseases in view of synergistic effects of health risk factors in the Kaliningrad enclave. Materials and methods . We conducted a retrospective analysis of the incidence of respiratory diseases in cadets of two military universities (n = 3,381, n = 2,013) by cohorts (local and non-resident students) for five academic years in general and by year. Results . The proportion of respiratory diseases in university cadets was as high as 70.9 ± 2.0 and 52.1 ± 1.1 % in Universities 1 and 2, respectively. The share of respiratory diseases in the first and fifth-year students was 72.3 and 59.9 % in University 1, and 60.3 and 38.1 % in University 2, respectively. The respiratory disease incidence in non-resident cadets was 1.8 and 1.2 times higher than that in locals: 1,102.6 ± 6.2 versus 617.7 ± 24.5 ‰ and 477.6 ± 14.1 versus 388.2 ± 16.1 ‰ (p = 0.001) in Universities 1 and 2, respectively. We found differences in the rates of acute sinusitis, acute tonsillitis, upper respiratory tract infections and influenza, community-acquired pneumonia, and lower respiratory tract infections between local and non-resident cadets. In the second university, differences in the incidence of acute sinusitis and upper respiratory tract infections were still observed in third-year students while in the first university they were still pronounced in cadets during the fourth year of study. We suppose that they might be attributed to learning conditions, ratios of local to non-resident cadets, differences in living conditions and nutrition between the students. Conclusion . Duration of the period of adaptation of military university cadets to conditions of learning is influenced by a synergistic effect of adverse environmental factors. Adaptation of non-resident cadets lasts longer due to acclimatization to weather and climate conditions of the enclave. The incidence of respiratory diseases proves the differences in learning conditions between the universities.
