The application of a single session of capacitive resistive electric transfer 24 h before exercise modifies the accelerometric pattern in standardbred racing trotters.

BACKGROUND: It has been reported that capacitive resistive electric transfer (CRET) increases blood circulation, hemoglobin oxygenation and temperature in muscles. The attributed benefits of these changes have been linked to improved athletic performance, enhanced muscle flexibility and fastening recovery from exercise-induced fatigue. For all of this, the present research aims to investigate whether the application of CRET 24 h before exercise affects the accelerometric pattern in horses during exercise. Six sound Standardbred trotters were subjected to a CRET session of 40 min of duration, applied on both sides of the neck, back and croup, 24 h before a training session. Training sessions consisted of a warming-up (WU) for 6400 m and a training bout (TB) at their maximal training speed for 1600 m. The same protocol was followed for the device off (sham protocol), also applied 24 h before the training session. CRET and sham experiments were separated by one week, the order of application of both was randomly defined for each individual and drivers were blinded for the duration of the experiment. During the training sessions, horses wore an accelerometer fixed at the sternal level. Speed, stride frequency (SF), length (SL), regularity and symmetry and accelerometric activities were measured during WU and TB. RESULTS: CRET increased speed, mediolateral and total accelerometric activities during WU and speed, SL, dorsoventral, longitudinal and total accelerometric activities during TB, but stride regularity and symmetry decreased. CONCLUSION: The application of CRET 24 h before exercise increased speed and accelerometric activities, results that highlight the need to evaluate the interaction between CRET and training in order to develop new methods to limit fatigue. However, the decrease in stride regularity and symmetry after CRET application could be negative effects, which could be attributed to the increased speed.

Detection of equine herpesvirus-1 (EHV-1) in urine samples during outbreaks of equine herpesvirus myeloencephalopathy.

BACKGROUND: Real-time PCR is the diagnostic technique of choice for the diagnosis and control of equine herpesvirus-1 (EHV-1) in an outbreak setting. The presence of EHV-1 in nasal swabs (NS), whole blood, brain and spinal cord samples has been extensively described; however, there are no reports on the excretion of EHV-1 in urine, its DNA detection patterns, and the role of urine in viral spread during an outbreak. OBJECTIVES: To determine the presence of EHV-1 DNA in urine during natural infection and to compare the DNA detection patterns of EHV-1 in urine, buffy coat (BC) and NS. STUDY DESIGN: Descriptive study of natural infection. METHODS: Urine and whole blood/NS samples were collected at different time points during the hospitalisation of 21 horses involved in two EHV-1 myeloencephalopathy outbreaks in 2021 and 2023 in Spain. Quantitative real-time PCR was performed to compare the viral DNA load between BC-urine samples in 2021 and NS-urine samples in 2023. Sex, age, breed, presence of neurological signs, EHV-1 vaccination status and treatment data were recorded for all horses. RESULTS: A total of 18 hospitalised horses during the 2021 and 2023 outbreaks were positive for EHV-1, and viral DNA was detected in urine samples from a total of 11 horses in both outbreaks. Compared with BC samples, DNA presence was detected in urine samples for longer duration and with slightly higher concentration; however, compared with NS, detection of EHV-1 in urine was similar in duration with lower DNA concentrations. MAIN LIMITATIONS: Limited sample size, different sampling times and protocols (BC vs. NS) in two natural infection outbreak settings. CONCLUSIONS: EHV-1 was detected in the urine from naturally infected horses. Urine should be considered as complimentary to blood and NS in diagnosis of EHV-1 infection.

HISTORIAL: PCR en tiempo real es la técnica diagnostica de preferencia para el diagnóstico y control del herpes virus equino­1 (EHV­1) en una situación de brote. La presencia de EHV­1 en torulas nasales (TN), muestras de sangre entera, cerebro, y medula espinal ha sido descrita en forma extensa; sin embargo, no hay informes de excreción de EHV­1 en orina, la detección del patrón de ADN, y el rol de la orina en la propagación vírica durante un brote. OBJETIVOS: Determinar la presencia de ADN de EHV­1 en muestras de orina durante un brote infeccioso natural y comparar los patrones de detección de ADN de EHV­1 en orina, capa leucocitaria (CL) y TN. DISEÑO DEL ESTUDIO: Estudio prospectivo en una infección natural en caballos hospitalizados. MÉTODOS: Muestras de orina y sangre entera/TN fueron recolectadas a distintos tiempos durante la hospitalización de veintiún caballos involucrados en dos brotes de mielo encefalopatía por EHV­1 en 2021 y 2023 en España. PCR a tiempo real cuantitativo fue llevado a cabo para comparar la carga de ADN viral entre muestras de CL­orina en 2021 y muestras TN­orina en 2023. Sexo, edad, raza, presencia de síntomas neurológicos, estatus de vacunación y datos de tratamiento fueron anotados para todos los caballos. RESULTADOS: Un total de diez y ocho caballos hospitalizados durante los brotes de 2021 y 2023 resultaron positivos a EHV­1, y ADN viral fue detectado en muestras de orina en un total de 11 caballos de ambos brotes. En comparación a muestras de CL, la presencia de AND fue detectado por mas largo tiempo y con una concentración ligeramente mas alta; sin embargo, en comparación a TN, la detección de EHV­1 en orina fue similar en tiempo pero demostró menor concentración de ADN. LIMITACIONES PRINCIPALES: Tamaño de muestra limitado, tiempos de muestreo diferentes, y de protocolos (CL vs. TN) en dos situaciones de brotes naturales. CONCLUSIONES: Se detecto EHV­1 en orina de caballos infectados naturalmente. La recolección, no invasive, de orina debería considerarse como un complemento a las muestras de sangre y TN en el control de caballos infectados en situaciones de brote.

Intra-Amniotic Inflammation or Infection: Suspected and Confirmed Diagnosis of "Triple I" at Term.

Chorioamnionitis (CA) at term of pregnancy can have an infectious and/or inflammatory origin and is associated with adverse outcomes. Triple I (intrauterine inflammation, infection, or both, TI) has been proposed to reduce the overdiagnosis of infection and neonatal overtreatment. The aim of this study is to identify clinical and histological variables that could predict adverse outcomes when TI is suspected and/or confirmed. This retrospective cohort study included 404 pregnancies (gestational age ≥ 37 weeks) that were divided into 5 all-inclusive and mutually exclusive groups. TI was defined according to the NICHD definition of 2015, and it could be confirmed (TI+) or not confirmed (TI-) via histological examination. Signs of infection/inflammation that did not conform to the definition of TI were classified as "clinical suspicion" and could be supported (CS+) or not supported (CS-) by histology. Cases of histological chorioamnionitis (HCA) without clinical manifestation represented a fifth group. Whole placental involvement (WPLI) was defined as a histological inflammation involving the maternal and fetal sides. There were 113 TI+, 30 TI-, 186 CS+, 35 CS-, and 40 isolated HCA cases. WPLI was diagnosed in 133 cases (39.2%). Composite neonatal outcome (CNO) occurred in 114 cases (28.2%) while composite maternal outcome (CMO) occurred in 192 cases (47.5%). Compared with CS+, TI+ was more predictive of CNO (p = 0.001), CMO (p < 0.001), and WPLI (p = 0.005). WPLI was related both to CNO (p < 0.001) and to CMO (p = 0.046). TI+ and WPLI showed similar sensitivity but different specificity in predicting CNO. At logistic regression, CNO was independently predicted by TI+ (OR 2.21; p = 0.001) and by WPLI (OR 2.23; p = 0.001). Compared with CS, TI is a better predictor of CNO and can be useful for the identification of newborns at risk.

A Comparison of the Efficacy of Two Omeprazole Formulations in the Treatment of Equine Gastric Ulcer Syndrome in Racehorses: A Blinded, Randomized Clinical Trial.

Equine gastric ulcer syndrome (EGUS) is the most common disease of the stomach in horses and treatment is based on the oral administration of omeprazole for at least 28 days. Aim of this study was to compare the efficacy of two formulations of oral omeprazole-powder paste and gastro-enteric resistant granules-in the treatment of naturally occurring gastric ulcers in racehorses. Thirty-two adult racehorses, aged between 2 and 10 years old, with clinical signs of EGUS were included in this blinded, randomized clinical trial. Two gastroscopies were performed to evaluate gastric lesions in the squamous or glandular mucosa before and after 28 days of treatment. After the first gastroscopy, 2/32 horses were excluded because affected by equine squamous gastric disease (ESGD) 1/4. The remaining horses were divided into 4 groups, and were treated with 2 formulations of omeprazole (gastroenteric resistant granules, group 1, or powder paste, group 3) or with 2 placebo formulations (granules, group 2, or paste, group 4). Treatments were performed in the placebo horses affected by ESGD or equine glandular gastric disease after the T28 gastroscopy control. No differences were found between groups at T0. Differences were found between T0 vs. T28 for granular (P = .002) and powder paste (P = .01) formulations. No differences were detected between the two groups receiving omeprazole formulations at T28 (0.34) and between T0 vs. T28 for either of the groups receiving placebo treatments. For all the variables, the size of the effect was greater than 0.5, proving that the treatments had a considerable effect. Gastro-enteric resistant granules and powder paste omeprazole showed similar efficacy in the treatment of ESGD. The glandular mucosa responded poorly to treatment with omeprazole.

Breath Alcohol Test Results in Equine Veterinarians after Performing an Abdominal Ultrasound with Ethanol.

Transcutaneous abdominal ultrasonography using alcohol saturation is used in the diagnostic workup of a variety of conditions in horses. The duration of the examination and the amount of alcohol used in each case may vary depending on several factors. The aim of this study is to describe the breath alcohol test results obtained by veterinarians performing abdominal ultrasound on horses. Six volunteers were enrolled, after written consent, and a Standardbred mare was used for the whole study protocol. Each operator performed a total of 6 ultrasounds by pouring the ethanol solution from a jar or by spray application, for a duration of 10, 30, and 60 min. An infrared breath alcohol analyzer was used immediately after completing the ultrasonography and at 5-min intervals until a negative result was obtained. Positive results were obtained for 0-60 min after the procedure. A statistically significant difference was found between the groups that used more than 1000 mL, 300-1000 mL, and less than 300 mL of ethanol. No significant differences were observed between the type of ethanol administration and the time of exposure. Based on this study, equine vets who perform ultrasound on horses can test positive at the breath alcohol test for up to 60 min following ethanol exposure.

Transthoracic echocardiography and its limitations in the diagnosis of congenital supernumerary aortic valve in a Thoroughbred.

Aortic valve malformation is a common congenital abnormality reported in human medicine. The malformation is characterised by an increased or decreased number of cusps. Anatomical variations of the aortic valve that have been documented in humans include unicuspid, bicuspid, quadricuspid and quinticuspid valves. Two reports described a quadricuspid aortic valve in horses associated with either a ventricular septal defect (VSD) or tetralogy of Fallot. In this case report we describe the clinical and echocardiographic findings of a horse with a quadricuspid aortic valve as single congenital abnormality, referred with history of exercise intolerance and an episode of paroxysmal atrial fibrillation. Limitations and risks of misdiagnosis that can be encountered with transthoracic echocardiography are also discussed. The reported case highlights the importance of echocardiographic screening in asymptomatic patients as congenital heart disease can be present without obvious cardiac signs. As advanced imaging on the equine thorax is still far from future possibilities for adult horses, this report may help to reach an accurate diagnosis with similar cases.

Respiratory sinus arrhythmia magnitude quantification as a potential marker of stress and pain in cows and sheep.

Respiratory sinus arrhythmia (RSA) provides a quantitative evaluation of 'vagal tone' and may be used for pain and stress assessment in livestock. The aim was to quantify the magnitude of RSA in cows and sheep. In 7 cows and 4 sheep standing at rest we measured the 3-lead electrocardiogram (ECG) together with the pneumogram, to identify inspiration and expiration. For each breath, RSA was the difference in instantaneous heart rate (HR) between the inspiratory peak and the expiratory trough, in percent of mean HR. The resting breathing rates (28 ± 2 and 32 ± 5 breaths/min in cows and sheep, respectively) were about twice those expected for similar size non-ruminants, in conformity with previous reports. Both species had long-period (>15 s) HR fluctuations. The average values of RSA, 1.4 ± 0.2% in cows and 7.8 ± 3.1 in sheep, were lower than those previously computed by an identical approach in humans (12%), dogs (40%) and horses (9%). In conclusion, by breath-by-breath analysis of instantaneous HR we measured RSA in both cows and sheep. Results from the present study represent a preliminary step in assessing whether or not RSA could be used as a biomarker for stress or pain in ruminants.

Validation of a new smart textiles biotechnology for heart rate variability monitoring in sheep.

Robust Animal-Based Measures (ABMs) are fundamental in order to assess animal welfare, however in semi-extensive sheep farming systems is not easy to collect ABMs without inducing additional stress in the animals. Heart rate variability (HRV) is a non-invasive technique of assessing stress levels related to animal welfare. It is considered a sensitive indicator of the functional regulatory characteristics of the autonomic nervous system. Several studies investigated the use of HRV for welfare assessment in dairy cows while research on sheep is scarce. Moreover, assessing HRV in small ruminants at pasture is critical because of the lack of a solution adoptable for field conditions. This study aimed to evaluate if a smart textiles technology is comparable to a Standard base-apex electrocardiogram (ECG) for measuring HRV in small ruminants. Eight healthy Massese dairy sheep were recruited. Standard base-apex ECG and smart textiles technology (Smartex ECG) were simultaneously acquired for 5 min in the standing, unsedated, unclipped sheep. The ECG tracings were recorded when animals were standing quietly. The Bland-Altman test and the linear regression analysis were applied after parameter extraction in time, frequency, and non-linear methods to compare Smartex against standard base-apex ECG systems. The Bland-Altman test was applied to all HRV extracted parameters (Mean RR, pNN50, RMSSD, LF/HF, SampEn, SD1, SD2, stdRR) to evaluate the agreement between the two different instruments, and a linear regression analysis was performed to evaluate the relationship between the two methods. The smart textiles biotechnology was simple to wear and clean. It can be worn without using glue and without shaving the sheep's wool, limiting animal handling and stress. Bland Altman test reported a robust agreement between the two systems. In fact, the regression analysis of HRV parameters showed that half of the parameters recorded had an R2 coefficient >0.75. Results also showed a very small reproducibility coefficient that indicated that the two methods were really close to each other. Smartex textiles technology can be used for HRV evaluation in sheep species as a potential ABM for animal welfare assessment.

Equine echocardiography: Can dobutamine infusion correct alterations due to sedation with alpha-2 agonists?

For the echocardiographic examination horses should not be sedated unless absolutely necessary because this alters cardiac dimensions and indices of function. However, some horses do not tolerate the echocardiographic procedure and require sedation to conduct the examination safely and obtain good quality images. The objective of this study was to evaluate whether the concurrent infusion of dobutamine in horses sedated with romifidine counteracts the cardiovascular changes observed with sedation alone. Twelve healthy untrained Standardbred mares were used. Three echocardiographic examinations were performed on the same day for each subject: a) without any treatment under resting conditions (WT); b) under sedation with romifidine administered intravenously (RT); c) under sedation with romifidine and concurrent intravenous infusion with dobutamine (RDT). A three-hour washout period was observed between each examination and the order of the examinations was randomly decided by rolling a dice. The measurements on the images recorded were performed offline at the end of the study protocol and at this point the operator was blinded to the horse and treatment administered. Left ventricular internal diameter (LVID) in diastole, left ventricular free wall (LVFW) in systole, and fractional shortening (FS) were higher in the WT group compared with the other two groups. No differences in the other M-mode and B-mode values were observed. A continuous rate infusion of dobutamine did not counteract the alterations caused by sedation and led to similar echocardiographic measurements to those obtained after romifidine administration.

Novel Board Game versus Active Case-Based Discussion to Teach Final-Year Veterinary Students the Diagnostic Approach to Clinical Cases.

Traditional lectures, where students listen passively, often do not reflect the complexity of real-life decision-making situations. Furthermore, modern students are using online devices for daily activities, and this has a challenging side effect for educators, as many people these days can only maintain their focus if topics are discussed in concise and engaging ways. For these reasons, there is growing interest in the use of games for educational purposes. The aim of this study was to introduce a board game based on the Clue game for final-year veterinary students during their practical activity in large animal medicine. This type of learning process was compared with a classical case-based discussion and evaluated via a survey delivered to the students to both test their acquired knowledge and obtain their evaluation of the activity. A total of 49 students were enrolled in this study. While the board game was evaluated significatively better than the traditional class, no statistically significant differences were observed for the answers given to questions assessing their veterinary skills. The proposed game requires few resources other than a case-based visual materials and analyses from clinical patients, a board, two dice, and some imagination to create cases at the appropriate level for students' knowledge. We conclude that this board game-based activity represents innovative techniques to teach clinical approaches in an interactive way with the same utility as a traditional class but is more enjoyable for the students.

Retrospective Matched Case-Control Study on the Use of CO2 Laser for the Treatment of Nonhealing Diabetic Foot Ulcers: The DULCIS-2 (Diabetic ULcer, CO2 Laser, and Infections) Study.

PURPOSE: Infection, which is one of the possible complications of diabetic foot ulcers (DFUs), makes the treatment of ulcers challenging because of its negative impact on healing processes and the high prevalence of multiresistant germs. This study is aimed at verifying the effect of a surgical CO2 laser (which reduces the bacterial load and allows a more accurate debridement), as compared with the traditional lancets, on the healing rate of DFU. METHODS: The present case-control retrospective analysis was performed on patients with chronic (>6 months) DFU with Texas grade >1, treated with 80 W surgical CO2 laser (DEKA SmartXide2 C80, El.En. Group) and compared with a matched sample of patients with similar characteristics, who were treated with a traditional surgical approach. The debridement was performed trying to achieve the complete removal of nonviable tissues. The principal endpoint was the proportion of patients healed at 6 months. All analyses were carried out with SPSS 25.0. The study protocol was approved by the local ethical committee. RESULTS: This study included 118 patients (59 cases and 59 controls). At 6 months, the proportion of healing patients was 35% and 18% in cases and controls, respectively (P = .034). The corresponding figure at 1 year was 62% and 38% (P = .009), whereas no difference was observed at 1, 2, and 3 months. No serious adverse event was observed. CONCLUSIONS: In this article, we show for the first time that CO2 laser treatment, in comparison with traditional surgical approaches, can be associated with an increased healing rate in patients with DFU.

Evaluation of a new portable 1-lead digital cardiac monitor (eKuore) compared with standard base-apex electrocardiography in healthy horses.

Recently, the use of smartphone ECG devices has been reported in humans and animals. Nevertheless, as the electrodes of these devices are inseparable, they can create only a precordial reading in veterinary species. Thus, although the smartphone ECG devices are considered valuable as a screening tool for the detection of some common arrhythmias, they are not always a reliable method for the measurement of the duration of the electrical deflections. The objectives of this study were to evaluate the feasibility of a novel smartphone ECG device, to report the readings obtained recorded simultaneously with a reference ECG system, and to compare the heart rate and duration of cardiac deflections obtained with the two methods. A total of 28 healthy mares of different breeds and age were included in this study and ECG recordings were obtained simultaneously with a reference ECG telemetry system with surface electrodes attached to the skin with alligator clips using a standard base-apex system and a smartphone ECG device with electrodes positioned alternatively with a standard and a modified base apex derivation. All the recordings obtained were considered acceptable for interpretation. An excellent agreement was found between the two methods for the evaluation of heart rate and polarity of cardiac deflections. No differences regarding number, duration and percentage of artifacts were found. This technology could become a valid diagnostic tool in the cardiological assessment of horses, in particular on the field.

Evaluation of Plasmatic Procalcitonin in Healthy, and in Systemic Inflammatory Response Syndrome (SIRS) Negative or Positive Colic Horses.

Colic horses show systemic inflammatory response syndrome (SIRS) clinical signs. Procalcitonin (PCT) showed increased circulating levels in sick horses. This study compares plasma PCT concentrations in healthy vs. SIRS negative/positive colic horses over time, and evaluates PCT and SIRS score potential correlation, to verify the usefulness of PCT for the evaluation of SIRS severity. Ninety-one horses were included; 43/91 were healthy, on basis of physical examination, blood work and SIRS score (score = 0), while 48/91 were sick colic horses, classified as SIRS-negative (score < 2) and positive (score ≥ 2). Moreover, a 0-6 point-scale SIRS score was calculated (assessing mucous membrane color and blood lactate concentration). PCT was evaluated at admission, and at 24, 48, 72 and 96 h, using a commercial kit for equine species. We verified by the ANOVA test PCT differences between healthy vs. colic horses, healthy vs. SIRS-negative or SIRS-positive colic horses, at all sampling times, and the correlation between the SIRS score at admission with the SIRS score. Statistically significant differences were detected between healthy vs. all colic horses and between healthy vs. SIRS-positive or negative horses at all sampling times. No correlation was observed between the SIRS score at admission and PCT values. PCT was statistically higher in colic horses compared to the healthy ones, suggesting a role as a biomarker for colic.

Ultrasonography Evaluation of Umbilical Structures in Clinically Healthy Donkey Foals during the First Week of Life.

The umbilicus is a potential access-point for pathogens in equine foal, causing umbilical infections and potentially life-threating illness. Early diagnosis based on ultrasonographic appearance and measurement is crucial to avoid severe complications and promptly implement appropriate therapy. This study ultrasonographically evaluates the umbilical remnants of donkey foals, in the first week of life. Fifteen healthy donkey foals were included in the study. The umbilical vein, arteries and urachus ultrasounds were performed at 24 h, 3 and 7 days of life, using a portable ultrasound machine and a 5-7.5 MHz multifrequency linear probe. The Kruskal-Wallis test and Dunn's multiple comparisons test were applied to verify differences in relation to time for all the umbilical remnants measured. Statistical significance was set at p < 0.05. No statistical differences were observed in relation to time regarding umbilical remnant measurements. A correlation was found between body weight and the left artery at T0. The regression of the umbilical remnant during the first week of life was slower compared with what was reported in equine foals but was comparable with the results on calves. Thus, the different regression timing needs be considered when evaluating donkey foals with umbilical remnant diseases within the first week of life.

Bronchoalveolar lavage fluid cytological findings in healthy Amiata donkeys.

Background: The approach to respiratory diseases in donkeys is similar to that for horses; nevertheless, Bronchoalveolar lavage fluid (BALF) and tracheal wash cytology in this species have been described only a few times in the literature. Aim: To describe BALF cytological findings in a cohort of 24 healthy Amiata donkeys. Methods: Bronchoalveolar lavage (BAL) was carried out via standing sedation with a large animal where the BAL catheter passed blindly through the nasal passage into the trachea. Results: The total nucleated cell count of the BALF was found similar to that already described in healthy horses and donkeys. No differences in the differential count were observed according to age and sex. A decreased macrophage percentage and an increased eosinophil percentage were observed in our donkey population when compared to the existing reference range for horses. Conclusion: The reference intervals for BAL cytology in donkeys may be significantly different for those referred for horses.

Blood glucose and subcutaneous continuous glucose monitoring in critically ill horses: A pilot study.

This pilot prospective study reports the feasibility, management and cost of the use of a continuous glucose monitoring (CGM) system in critically ill adult horses and foals. We compared the glucose measurements obtained by the CGM device with blood glucose (BG) concentrations. Neonatal foals (0-2 weeks of age) and adult horses (> 1 year old) admitted in the period of March-May 2016 with clinical and laboratory parameters compatible with systemic inflammatory response syndrome (SIRS) were included. Glucose concentration was monitored every 4 hours on blood samples with a point-of-care (POC) glucometer and with a blood gas analyzer. A CGM system was also placed on six adults and four foals but recordings were successfully obtained only in four adults and one foal. Glucose concentrations corresponded fairly well between BG and CGM, however, there appeared to be a lag time for interstitial glucose levels. Fluctuations of glucose in the interstitial fluid did not always follow the same trend as BG. CGM identified peaks and drops that would have been missed with conventional glucose monitoring. The use of CGM system is feasible in ill horses and may provide clinically relevant information on glucose levels, but there are several challenges that need to be resolved for the system to gain more widespread usability.

COVID-19 PANDEMIC LIFESTYLE: STUDENTS MENTAL HEALTH CHALLENGES.

OBJECTIVE: The aim: To determine how quarantine restrictions affect the lifestyle of Ukrainian students, and their mental health. PATIENTS AND METHODS: Materials and methods: 37 student essays were submitted to the university contest held at Lviv Polytechnic University in May-June 2020. They were analyzed with the help of qualitative thematic analysis and standard qualitative analysis method. Essays are focused on a list of issues important for assessing the social well-being of students during quarantine. Each fragment of essay's answer was coded into the data matrix system according to either multiple or single themes, built in the statements. The thematic analysis identified several categories that determine students' attitude to the pandemic situation and its consequences for them. RESULTS: Results: It is determined that students' lifestyle, including study and leisure, has changed significantly, which has affected their mental health. Learning online provoked a number of emotional disorders. At the same time, the desire for communication in person and self-improvement increased. «Quarantine lessons¼ were divided into categories: challenges, threats and opportunities. Threats and challenges were considered at the global level, while opportunities affected rather the personal level. CONCLUSION: Conclusions: Mental health of students disorders: anxiety, restlessness, fear, self-doubt, feelings of loneliness, panic, sleep disturbances, and increased fatigue indicate the negative effects of the pandemic. At the same time, recording such facts as the feeling of satisfaction from communication with loved ones, the ability to help them, the desire for self-improvement, etc. allows to say about the positive effects.

THE QUALITY OF LIFE FOR STUDENTS IN EDUCATIONAL INSTITUTIONS: CURRENT SITUATIONS AND BASIC PRINCIPLES OF PSYCHOHYGIENIC IMPROVEMENT.

OBJECTIVE: The aim: To develop the key principles of psychohygienic improvement of the processes of personality formation and enhancement of the quality of life of pupils and students of modern educational institutions of various types. PATIENTS AND METHODS: Materials and methods: While working out the basic principles of psychohygienic correction of the processes of personality development and improvement of the quality of life of pupils and students of modern educational institutions of various types, we have conducted surveys of the adolescent boys and girls studying at five modern educational institutions in Ivano-Frankivsk city, namely Vasyl Stefanyk Precarpathian National University, Ivano-Frankivsk Finance Commercial Cooperative College named after Stepan Hranat, Ivano-Frankivsk State Music School named after Denys Sichynskyi, Ivano-Frankivsk Vocational Lyceum of Road Transport and Construction No. 15, and Ivano-Frankivsk Boarding Lyceum for Gifted Young People from Rural Areas. A total of 420 pupils and students studying at different types of educational institutions took part in the survey. They were in both natural and preformed conditions due to application of the program of psychophysiological effects on the body, psychohygienic correction of personality development processes and improvement of the quality of life of pupils and students. RESULTS: Results: While conducting the research, we have noted that the practical application of the program of psychophysiological effects on the body, psychohygienic correction of personality development processes and improvement of the quality of life of pupils and students occurs at mental, personal and psychophysiological levels of the adolescent boys and girls, anticipating correction of emotional, motivational and behaviour-based key characteristics of personality, psychophysiological adaptation and quality of life, thus being a platform for development of creative potential, self-analysis, self-expression and self-control skills, as well as discovery of positive landmarks and meaning of life of the boys and girls. CONCLUSION: Conclusions: The obtained data demonstrate that implementation of the program of psychophysiological effects on the body, psychohygienic correction of personality development processes and improvement of the quality of life of pupils and students, which includes: study of the level of development of psychophysiological functions, personality characteristics and indicators of the quality of life in each of the participants as well as taking into account the leading areas of their development within certain frameworks of educational process (the milestone of psychodiagnostics and assessment of the level of development of psychophysiological functions and personality traits); performing a set of exercises to relieve muscle spasms, isometric and respiratory gymnastics, as well as exercises of asymmetric gymnastics (the milestone of physical impact); application of psychophysiological component (the milestone of psychophysiological influence); introduction of a psychohygienic component (the milestone of psychohygienic correction) serves the basis for creating the foundation for activating positive changes in the peculiarities of psychophysiological and mental adaptation and characteristics of the quality of life of modern youth at educational institutions of various types.
