Background: Post-fracture prolonged immobilization or post-operative elbow stiffness is relatively common and markedly interferes with normal upper extremity function. This study aims to evaluate and compare the levels of patient satisfaction and quality of life in individuals with post-elbow fracture stiffness who undergo Proprioceptive Neuromuscular Facilitation (PNF) stretching versus those who receive passive stretching.Methodology: This (six months) analytical comparative cross-sectional study was conducted at various healthcare institutions. The sample consisted of 377 patients using non-probability convenient sampling. Inclusion criteria included specific types of elbow fractures, a minimum immobilization period of three weeks, and limited range of motion (ROM). Exclusion criteria covered various medical and psychological conditions. Standardized questionnaires Short Form 36 Health Survey Questionnaire (SF-36) and Patient Satisfaction Questionnaire (PSQ-18) were used for measuring Quality of life and patient satisfaction. Data analysis was done using SPSS version 22.Results: Short Form 36 Health Survey Questionnaire scores were significantly higher in the PNF Stretching group (mean 82.34 ± 6.63) compared to the Passive Stretching group (mean 63.98 ± 14.42), with a p - value of 0.000. Similarly, Patient satisfaction questionnaire scores were significantly higher in the PNF Stretching group (mean 77.61 ± 4.43) compared to the Passive Stretching group (mean 70.93 ± 8.49), with a p - value of 0.000. These findings indicate that there is a statistically significant difference observed between the two groups.Conclusion: There is a statistically significant difference observed between both groups as the patients undergoing PNF stretching have higher satisfaction and better quality of life, in comparison to the passive stretching group.

Background: Factors like emotions, lifestyle choices, and physical activities, including posture changes, have a significant impact on cardiovascular indicators like blood pressure and heart rate. The study aims to examine the cardiovascular reactions in individuals with type 2 diabetes while performing the head-down crooked kneeling (HDCK) or Sujood position, resembling poses found in hatha yoga. This position emphasizes relaxation, body awareness, and meditation. Those with type 2 diabetes who engage in yoga have reported enhancements in their management of blood sugar levels and insulin resistance. Methodology:  A cross-sectional study was conducted in different hospitals. The sample size was 312 which was calculated by using the Rao soft calculator. The participants were selected by non-probability convenience sampling technique. Inclusion Criteria were male and Female diagnosed with Type 2 DM, Subjects with a history of smoking, Cognitive Impairment, Sepsis, Cardiac pathology, Respiratory disorders, and Malignancy were excluded. Blood pressure and heart rate were monitored initially, during the Crooked Down Kneeling position, and after the Crooked Down Kneeling Position. A Digital Sphygmomanometer was used to measure blood pressure and a pulse rate-demographic Assessment form was used to collect data. Ethical consideration is maintained. Informed consent was taken from participants. Results: The result shows a significant effect of head down crooked kneeling position on cardiovascular response in type 2 diabetic patients (p < .001). Systolic, diastolic blood pressure, and heart rate before, during, and after HDCK were significantly increased (p < .001) as compared to the baseline value, and after 5 min returning to the upright position it reverted to the initial value. Conclusion: This study revealed a significant increase in systolic and diastolic blood pressures and an increase in pulse rate during HDCK. Also, our findings showed no significant gender difference in the effect of HDCK on all the other cardiovascular parameters except systolic bp.

Globally, all people deserve the highest level of respect for their dignity, rights, and health. Bioethics has been recognized as a powerful discipline that aims to ensure such respect. Fritz Jar (1895–1953) and Van Rensselar Potter (1911–2001) will remain heroic men who ushered in the existence of the discipline of bioethics. Bioethics has been recognized as the science of survival and a bridge to the future. Thus, bioethics aims to enrich people’s wisdom. Wisdom is the knowledge of how to use knowledge for human survival and improvement in the quality of life. Worldwide, all people must widely possess such knowledge. Unfortunately, after many years of existence, implementing the principles and goals of bioethics remains centralized and confined to academic fields. Due to its centralized status, few branches of bioethics have been recognized. Besides, both pre-standard and standard practices still exist in the field of bioethics. Healthcare bioethical principles have been mentioned in numerous publications. However, healthcare bioethics has not been recognized as a vital branch of bioethics. The lack of well-established healthcare bioethics hinders strategies for eradicating many of the ephemeral and heuristic approaches that are still obstructing the achievement of optimum health status for numerous people worldwide. Integrating bioethical principles in all healthcare sectors in decentralized manners would lead to the existence of healthcare bioethics. The purpose of this manuscript is to describe healthcare bioethics as a vital branch of bioethics with respect to its description, branches, core principles, functions, system components, and pre-standard and standard practices of healthcare bioethics.

Hypersexual disorder, also known as compulsive sexual behavior or sex addiction, is a complex and clinically significant condition characterized by intense and recurrent sexual fantasies, urges, or behaviors that significantly disrupt an individual’s daily life and overall well-being.

By synthesizing information from existing literature and research, this review aims to deepen our understanding of hypersexual disorder and contribute to the development of evidence-based interventions.The review begins by exploring the evolution of the term “hypersexual disorder” and its current status in diagnostic classifications. It then delves into the potential etiological factors contributing to the development of hypersexual behaviors, including neurobiological, genetic, and psychosocial factors.Furthermore, the review discusses the common comorbidities associated with hypersexual disorder, emphasizing the importance of addressing co-occurring mental health conditions in treatment planning. The psychological and physiological effects of hypersexual behaviors on affected individuals are examined, underscoring the urgency of early intervention and comprehensive treatment.The assessment and diagnosis of hypersexual disorder are thoroughly examined, considering the challenges and methodologies involved in identifying and evaluating affected individuals. Cultural and ethical considerations are highlighted, stressing the significance of providing culturally sensitive and ethical care to diverse populations.In the context of treatment, the review discusses various therapeutic approaches, including psychotherapy, medication, support groups, and harm-reduction strategies. The need for evidence-based treatments tailored to hypersexual disorder is underscored while recognizing the challenges of developing standardized protocols in this evolving field.Finally, future research directions are outlined, focusing on the standardization of diagnostic criteria, prevalence studies, neurobiological investigations, and the integration of cultural competency in treatment approaches.In conclusion, this review paper aims to contribute to a comprehensive understanding of hypersexual disorder and its implications for affected individuals and society. By exploring the multifaceted aspects of the condition, this review seeks to provide insights into effective treatment approaches and inspire further research in the study of hypersexual disorder.

The cosmetic industry is searching for new active ingredients from renewable natural sources to make more environmentally friendly and safe products. Botanical extract is a nearly limitless source of these new actives due to the current consumer demands as well as international regulations. Due to both their fragrant nature for the creation of fragrances and perfumes and the numerous advantageous properties of their individual components (EOCs), such as anti-inflammatory, antimicrobial, and antioxidant properties, essential oils (EOs) emerge as a very common natural ingredient in cosmetics and toiletries. Additionally, nowadays, the cosmetic industry includes EOs or different mixtures of their individual components (EOCs), either as active ingredients or as preservatives, in various product ranges (e.g., moisturizers, lotions, and cleansers in skin care cosmetics; conditioners, masks or anti-dandruff products in hair care products; lipsticks, or fragrances in perfumery). However, because each essential oil’s distinct chemical profile is linked to a different set of advantages, it is challenging to generalize about how they might be used in cosmetics and toiletries. Formulators frequently spend time looking for appropriate combinations of EOs or EOCs to achieve particular advantages in the finished products. The literature on the most recent developments in the use of EOs and EOCs in the production of cosmetic products is updated in this work’s review of the literature. Additionally, certain particular issues pertaining to the security of EOs and EOCs in cosmetics will be covered. It is expected that the information contained in this comprehensive review can be exploited by formulators in the design and optimization of cosmetic formulations containing EOs.

The most indications of primary cesarean section in grandmultipra malpresentation, fetal distress, prolonged first and second stage of labour. Most CS were emergency. 

Loneliness was a major concern of people during the recent COVID-19 pandemic. Now, that the pandemic is mainly gone, it is still a global issue. This commentary reviews the impact on that loneliness has on our cognitive, behavioral and affective functioning. These effects are described, along with the stigma that often accompanies loneliness and which makes it hard for people to acknowledge and admit that they are lonely, and seek help from healthcare professionals. This commentary, aside from describing the various negative implications of loneliness, highlights the need for society to address the issue. While it cannot be eliminated, the population can be taught how to recognize it, and how to offer assistance to those who struggle with it.

Hydrogel-based formulations hold significant promise for treating ocular diseases that impact the posterior segment of the eye. These formulations exhibit the ability to surmount ocular barriers and offer sustained drug release, rendering them efficacious drug delivery systems. This article addresses the challenges linked to treating disorders affecting the posterior eye segment and underscores the imperative for less invasive drug delivery methodologies. We further delve into diverse contemporary ocular dosage forms, encompassing gels, nanostructures, and implants, with a specific emphasis on hydrogels. Hydrogels offer several merits, including precise targeting, sustained release, enhanced bioavailability, and non-invasiveness. Moreover, they curtail the risk of adverse effects and foster patient adherence. An enthralling advancement is the amalgamation of hybrid drug delivery systems, integrating nanoparticles, liposomes, dendrimers, and stimuli-activated nano-systems, with hydrogels for posterior eye ailment treatment. These hybrid nano-systems exhibit promise in enhancing drug stability, prolonging drug release, and pinpointing specific tissues within the posterior segment. We also provide an overview of ongoing clinical trials and approved hydrogel-based drug delivery systems, like Retisert and Ozurdex. These systems have demonstrated efficacy in managing chronic non-infectious uveitis, Age-related Macular Degeneration (AMD), and diabetic macular edema. Nevertheless, challenges persist, including optimizing bioavailability, maintaining drug stability, and implementing personalized treatment approaches. The incessant evolution of gel-based drug delivery systems stands to substantially enhance patients’ quality of life and establish new benchmarks in treating posterior eye diseases. The future of ophthalmology brims with excitement, as gel-based drug delivery systems hold the potential to revolutionize ocular therapies, providing effective remedies for an array of vision-related afflictions.

Background: Inflammatory bowel disease (IBD) is characterized by non-specific chronic relapsing inflammation of the gastrointestinal tract and extra-intestinal manifestations. It includes Crohn’s disease (CD) ulcerative colitis (UC) and unclassified colitis.Objective: To assess the clinical presentations and management of inflammatory bowel disease in Sudanese patients.Methodology: Prospective, cross-section hospital-based study was conducted at Soba University Hospital (SUH) and Ibn Sina Hospital, in a period from December 2016 to March 2017. Data was entered and analyzed with SPSS, an interview questionnaire containing demographic, clinical, type of IBD, treatment, and complications.Results: A total of 64 IBD patients were included, 50% were diagnosed with UC, 28.1% with CD and 21.9% unclassified type. The most frequent age in UC patients was 41 – 50 years 34.4%, in CD was 31- 40 years 38.9% and for the unclassified type was 51 – 70 years 57.2%. The female was higher in CD while males were higher in Ulcerative colitis disease, symptoms were diarrhea, rectal bleeding, abdominal pain, rectal pain, tenesmus and fatigue. Study participants received 5 amino salicylic acid, and steroids, especially in the oral formulation. Minimal usage of topical forms, azathioprine, and biological agents. Conclusion: The study concluded UC is more common than CD. This should be taken into account as an important update for internal medicine professionals to adjust their expectations and lines of diagnosis, and management. The emergence of the unclassified type in Sudan requires good communication between the pathologists and the physicians and MDT meetings in every patient with suspicion of IBD.

Background: Spirituality has been strongly associated with good blood pressure control as it forms a strong coping mechanism in hypertensive patients. This hospital-based cross-sectional study was done to determine the relationship between spirituality and blood pressure control among adult hypertensive patients in rural Southwestern Nigeria to achieve good blood pressure control.Method: The selection was done by systematic random sampling technique. Socio-demographic and clinical information were obtained through semi-structured interviewer-administered questionnaires. The level of spirituality was assessed using the Spiritual Perspective Scale. Data were analysed using the Statistical Package for Social Sciences version 20.0. Statistical significance was set at p ≤ 0.05.Results: The mean age of the respondents was 61.1 ± 11.1 years. More than half (52.6%) had a high level of spirituality and more than two-thirds (67.1%) of respondents had controlled blood pressure. Respondents with a high level of spirituality were 4.76 times more likely to have good blood pressure control {p < 0.001, 95% CI (1.05-14.99)} than those with a low level of spirituality. Conclusion: Proper understanding and effective utilization of this relationship will assist health professionals and researchers in the appropriate integration of this concept into patients’ holistic care with the aim of achieving better blood pressure control among hypertensive patients.

Bone marrow and the central nervous system are both protected by bone. The two systems are interconnected not only structurally but also functionally. In both systems specialized cells communicate through synapses. There exists a tridirectional communication within the neuroimmune network, including the hormonal system, the immune system, and the nervous system. Bone marrow is a priming site for T cell responses to blood-borne antigens including those from the central nervous system. In cases of auto (self) antigens, the responses lead to immune tolerance while in cases of neo (non-self) antigens, the responses lead to neoantigen-specific T cell activation, immune control, and finally to the generation of neoantigen-specific immunological memory. Bone marrow has an important function in the storage and maintenance of immunological memory. It is a multifunctional and very active cell-generating organ, constantly providing hematopoiesis and osteogenesis in finely-tuned homeostasis. Clinical perspectives include mesenchymal stem cell transplantation for tissue repair within the central nervous system.

Objectives: The study’s goals are to evaluate the management of Stroke Mimics (SMs), conditions with stroke-like symptoms but non-vascular origins. It seeks to avoid the unnecessary intravenous thrombolysis, the target therapy delays and determine the best SMs diagnosis approach.Materials and methods: A review was conducted of all patients admitted to the Emergency Department under a “stroke code” from January 1, 2018, to January 31, 2019. Anamnestic and clinical data, along with information on neuroimaging protocols and findings, were collected. Advanced MRI sequences, such as Arterial Spin Labeling (ASL) MR perfusion and MR spectroscopy, were revised to confirm the diagnoses.Results: 513 stroke codes were found; a neurovascular disease was diagnosed in 414 cases: 282 ischemic strokes and 73 intracranial hemorrages and 59 TIAs. The 99 SMs included, 13 infections, 12 syncopes, 11 epileptic seizures, 11 hemodinamic conditions, 10 tumors, 9 metabolic disorders, 9 diziness, 7 migraines, 4 drug/alcohol intoxication, 3 functional disorders, 3 acute hydrocefalus, 2 multiple sclerosis, 2 arteriovenous malformations, 1 spinal cord compression and 2 unexplained conditions. Specific neuroimaging findings were evaluated for all cases. Positive and negative predictive values of clinical diagnosis of SM were respectively 0.23 and 0.35. 125 SM patients underwent MRI examination, 40 of which within 3 hours from the activation of stroke code. Advanced MRI sequences as ASL, MR perfusion, MR spectroscopy were used to reach the correct diagnosis.Conclusions: Advanced multimodal MRI can be a valuable tool in the assessment of, particularly in cases where conventional imaging techniques such as DWI-FLAIR mismatch are inconclusive. The novelty of this retrospective study is to demonstrate that the consistent use of arterial spin labeling perfusion in cases with stroke code leads to a rapid and accurate diagnosis of SMs. The implementation of an MRI-based pathway can expedite the diagnosis and treatment of underlying non-vascular causes such as SMs.

This report illustrates and provides a novel explanation for post-trabeculectomy improvements in the visual field, cup disc contours, and apparent deepening of an arcuate nerve fiber layer (NFL) defect after trabeculectomy for open-angle glaucoma. These changes are all plausible manifestations of recovered axonal transport and thickening retina, previously thinned by elevated intraocular pressure (IOP). Serial pre-and post-operative clinical fundus photos in case 1(A,B) demonstrate increased prominence of an inferior temporal arcuate nerve fiber layer defect, improved cup disc ratio, and visual field following eye pressure lowering by + 50% after trabeculectomy. Case 2 (C,D) also demonstrates obvious cup disc improvement in post-operative photos with associated improvement in visual field after trabeculectomy and lowering IOP by + 30%. We suggest that elevated IOP suppresses primarily orthograde axonal transport resulting in nerve fiber layer (NFL) thinning that can recover back to normal thickness when IOP is surgically lowered by the magnitude achieved in these two examples.

Background and objectives: Periodontal disease, as an inflammatory pathology, induces hemodynamic changes that can be evaluated by different unbiased methods such as laser Doppler flowmetry. This clinical investigation assesses laser Doppler as a non-invasive procedure to monitor gingival vascularization and its potential relationship with the response to treatment of periodontal disease.Materials & methods: 45 sites of white Spanish patients with active periodontitis undertake a complete periodontal analysis. This included periodontal pathogens identification along with the monitoring of the gingival margin microvascularization using a Doppler laser at the points exhibiting the most periodontal damage. All assessments were performed before and after periodontal combined treatment PCT (scaling, root planing, and antibiotic therapy prescription) (n = 45 sites).Results: Parameters of periodontal disease showed a positive correlation with pathogen levels. Blood flow readings decreased significantly after PCT (p < 0,05), although this parameter was not statistically correlated with periodontal nor microbial assessments in a significant range.Conclusion: Laser Doppler is a complementary method of monitoring periodontal inflammation to traditional techniques of clinical periodontal evaluation. Further studies are necessary to determine its usefulness as a predictive method of periodontal disease evolution.

Purpose: To compare between the two commonly used methods to deliver the fetus in emergency cesarean section with fully dilated cervix and impacted fetal head; vaginal push up of the fetal head and reverse breech extraction regarding safety and efficacy.Methods: A retrospective observational study was conducted 152 women underwent emergency CS with fully dilated cervix and impacted fetal head were divided into two groups; Group 1, vaginal push (n = 96) and Group2, reverse breech delivery (n = 56). Data variables were collected and analyzed to evaluate whether either method is more safe regarding maternal and fetal outcomes.Results: There was a significant higher percentage of extension of uterine incision in group 1 (p = 0.002). Also, there were significant higher mean values of operative time and operative blood loss in group 1 (p = 0.008 and 0.015; respectively). On the other hand, there was a significantly shorter uterotomy to delivery time in group 1 (p < 0.001). There was a significantly higher mean value of APGAR score at one minute in group 1 (p = 0.043) but no significant difference between the two groups regarding APGAR score at five minutes, atonic PPH, postoperative blood transfusion and hospital stay.Conclusion: Vaginal push technique was associated with significantly higher intraoperative maternal morbidity but postoperative maternal morbidity and fetal outcomes were comparable between both groups. Push method (after uterine incision) is still the preferable method and larger studies are required to assess the fetal safety with reverse breech extraction.

Amyotrophic lateral sclerosis (ALS) disease is characterized by degeneration of motor neurons and elevation of brain oxidative stress. Previous studies demonstrated the neuroprotective effects of Telomerase reverse transcriptase (TERT) from oxidative stress. We showed that increasing TERT expression in the brain of the Tg hSOD1G93A mouse ALS model attenuated the disease pathology and increased the survival of motor neurons exposed to oxidative stress. How TERT increased the survival of motor neurons exposed to oxidative stress is not yet clear. Here we investigated the consequence of TERT depletion in motor neuron cells under normal and oxidative stress conditions and in mouse brains of TERT knockout mice, on the expression and activity of SOD1 and catalase enzymes. Depletion of mouse TERT caused mitochondrial dysfunction and impaired catalase and SOD1 activity. Compensation with hTERT restored the activity of SOD1. SOD1 expression increased in the brain of TERT KO and in ALS mice and decreased in the brain of WT mice treated with telomerase-increasing compounds. We suggest that the ability of TERT to protect neurons from oxidative stress affects the expression and activity of SOD1, in a TERT-dependent manner, and supports the notion of TERT as a therapeutic target for neurodegenerative diseases like ALS.

Introduction: Treatment failure and claims against physicians may have many negative consequences. Orthopedic surgeons have always been among the most used specialists. Therefore, the investigation of causes and the process of these claims can help reduce the negative effects of medical malpractice on physicians and society.Materials and methods: This retrospective study investigated all medical orthopedic negligence cases in Sari, Iran, from March 2015 to March 2020. Data were collected using a researcher-made checklist and analyzed in SPSS software (V-21).Results: Out of 57 finalized cases investigated in this study, surgeons were found liable in 23 (40%) cases. The mean ± SD age of patients was 41 ± 19.3. Moreover, the level of education had a positive correlation with the surgeon’s liability. The most common cause of complaint was reduced Range of motion (ROM) and the most common type of complained surgery was “open reduction & internal fixation” (ORIF). None of the surgeons were found liable due to surgical site infection or device failure. The mean ± SD time for the file processing was 11.1 ± 10.1 months. The mean indemnity payment was 320 million Iranian Rials (9.7% of indemnity for death in Iran).Conclusion: The most effective way to reduce medical complaint cases is to increase the knowledge and skill levels of physicians. The lack of a blinded arbitration system in both organizations could lead to bias in the case assessment process. Moreover, considering the long processing time of the claims, it is recommended that new technologies should be used to reduce the time and increase the accuracy of the final verdict. The absence of a ‘no-fault’ compensation program is a significant flaw in Iran violating patients’ rights. Also, more studies are needed to evaluate justice and equality in Iranian medical commissions.

Kalanchoe pinnata, also known as air leaf or life leaf, is a plant used in traditional medicine in different world regions. In Mexico, it is included in the Atlas de la Medicina Tradicional Mexicana with a wide variety of applications, such as antimicrobial, anti-inflammatory, anticancer, and antihistamine, among others. However, neither a secondary metabolite profile of the flower has been reported nor information on its possible toxicity. The latter is the purpose of this work. A phytochemical profile of extracts with solvents of different polarity (aqueous, methanol, ethanol, and ether) was carried out. In this profile, the structural compounds could be qualitatively determined by chemical reactions, and some changes in coloring or precipitation were observed. The acute toxicity test of the extracts was performed with an aquatic organism, Artemia sp, and a terrestrial organism Eisenia foetida, as well as the evaluation of the antioxidant capacity of the extracts in the organism of Eisenia foetida. The ABTS radical method and TROLOX were applied as synthetic antioxidants for the evaluation of the inhibition percentage. Most important secondary metabolites were qualitatively identified in the extracts of K. pinnata flowers. Mainly in the alcoholic extracts (methanol and ethanol) tannins, alkaloids, and flavonols were found. As mentioned above, they are reported to have toxicological effects. The toxicity and antioxidant activity tests confirm the preliminary results obtained in the identification of secondary metabolites. It is therefore concluded that the flower of Kalanchoe pinnata contains secondary metabolites that may be of great therapeutic interest.

Background: CPTs are rare intraventricular papillary neoplasms derived from the choroid plexus epithelium. Anti-collagenase and extracellular matrix which have not been expressed in brain tumors. Objective: The purpose of this study was to investigate the expression levels of collagen type VI, anti-collagenase, laminin, MM9, claudins 1 and 5, N and E cadherins, and collagen VII, tejido, and collagen degradation enzyme complexes in choroid plexus tumors.Materials and methods: We studied the expression of adhesion molecules, extracellular matrix, and anticollagenase with an immunohistochemistry approach and electron microscopy analysis in 42 choroid plexus tumors. Results: 28(67%) were choroid plexus papillomas, 8 (19%) were atypical choroid plexus papillomas and 6 (14%) were choroid plexus carcinomas. The Ki67-li and MVD increased from CPC to ACPP, being the highest in malignant tumors as well as a strong immunoexpression of anti-collagenase and were inverse correlation with claudin 5, E, and N cadherin and collagen IV immunoexpressions which added further significant information to the prognosis and varied according to the histologic classification. By ultrastructure, the loss of basal membrane and cilia, disorganization, and proliferation of ECM were observed in CPC. Cerebral homeostasis largely results from the ability of both the Blood–Brain Barrier (BBB) at the brain microvascular endothelium and the Blood–Cerebrospinal Fluid Barrier (BCSFB) at the epithelium of the Choroid Plexuses (CPs), to control the composition of the CSF and cerebral extracellular fluid. Under expression of the tight junction proteins occludin, claudin-1 and claudin-5 are key molecular abnormalities responsible for the increased permeability of tumor endothelial tight junctions. Conclusion: The loss of basement membrane and ECM overexpression could be considered as a poor prognosis predictor in CPT. Anti-collagenase and MMP9 overexpression could be related to basal membrane and BBB plasticity in CPTs.

The purpose of this work is to implement methods and develop tools for nonlinear dynamic identification of the Oculomotor System (OMS) “input-output” in the form of Multidimensional Transient Functions (MTF) based on eye tracking data and their use in an information system for diagnosing the psychophysiological state of a person. The object of the study is the process of diagnosing the psychophysiological state of an individual based on innovative eye-tracking technology. The subject of the research is computational algorithms and software for determining diagnostic features based on identification data of compulsory medical insurance in the form of MTF, constructing a Bayesian classifier using machine learning in the established space of the most informative features. A methodology has been developed and implemented for the experimental study of human compulsory mental health using innovative eye-tracking technology to record compulsory mental health responses to test visual stimuli. The obtained empirical data from input-output studies are used for the identification of OMS based on Volterra polynomials. Experimental studies of compulsory medical insurance of respondents were carried out before and after the working day. Based on the data obtained using the Tobii Pro TX300 eye tracker, the transient functions of the first, second, and third orders of the OMS were determined. Variability of second and third order transient functions was revealed for different psychophysiological states of the respondent (normal or fatigue). Thus, it seems appropriate to use MTF in diagnostic studies in the fields of neuroscience and psychology. Information technology for diagnosing human psychophysiological conditions has been further developed through the use of compulsory health insurance information models based on Volterra polynomials as a source of primary data. This allows for an increase in the accuracy of OMS modeling and, consequently, enhances the reliability of diagnosis within the framework of the proposed heuristic features. A set of heuristic features is proposed, which are determined using integral and differential transformations of the MTF OMS. The information content of individual features and all possible combinations of them in pairs was studied using the Probability of Correct Recognition (PCR) indicator. Two-dimensional feature spaces with the maximum PCR value (0.938) were identified during the diagnosis of a person’s psychophysiological state.
