Epigenetic processes associated with neonatal spinal transection.

In early development, the spinal cord in healthy or disease states displays remarkable activity-dependent changes in plasticity, which may be in part due to the increased activity of brain derived neurotrophic factor (BDNF). Indeed, BDNF delivery has been efficacious in partially ameliorating many of the neurobiological and behavioral consequences of spinal cord injury (SCI), making elucidating the role of BDNF in the normative developing and injured spinal cord a critical research focus. Recent work in our laboratory provided evidence for aberrant global and locus-specific epigenetic changes in methylation of the Bdnf gene as a consequence of SCI. In the present study, animals underwent thoracic lesions on P1, with cervical and lumbar tissue being later collected on P7, P14, and P21. Levels of Bdnf expression and methylation (exon IX and exon IV), in addition to global methylation levels were quantified at each timepoint. Results indicated locus-specific reductions of Bdnf expression that was accompanied by a parallel increase in methylation caudal to the injury site, with animals displaying increased Bdnf expression at the P14 timepoint. Together, these findings suggest that epigenetic activity of the Bdnf gene may act as biomarker in the etiology and intervention effort efficacy following SCI.

Shoulder injuries in Brazilian professional football players: epidemiological analysis of 3828 games

ObjectivesFootball is a globally played sport that poses potential risks for musculoskeletal injuries. Upper-limb injuries have a lower incidence rate than lower-limb injuries but can still cause absenteeism and performance impairment in football players. This descriptive epidemiological study aimed to evaluate and compare the epidemiological data on shoulder injuries among professional football players in two major Brazilian football championships. MethodsData were collected throughout the championships, and club physicians medically evaluated each player during official games using two online forms. The collected information included the player's age and position, injury diagnosis, laterality, location on the field where the injury occurred, playing time, imaging examinations performed, need for surgical treatment, time to return to play (TRP), and recurrence of the injury. The incidence of injuries was evaluated using the Federation Internationale de Football Association (FIFA) incidence formula. ResultsA total of 107 shoulder injuries were recorded (4.3% of all injuries), with a FIFA incidence of 0.847. Glenohumeral dislocations (GHDs) and acromioclavicular dislocations (ACDs) accounted for 37.38% and 35.51% of all shoulder injuries, respectively. Goalkeepers and defenders presented, respectively, a 2.15 and 1.57 times increased risk of suffering shoulder injuries, while attackers presented a 0.63 times decreased risk. Injury recurrence was observed in 14.95% of cases, with GHDs and ACDs showing recurrence rates of 35.00% and 5.26%, respectively. Surgery was performed in 9.35% of cases, with GHDs representing 50% of all surgeries. The average TRP was 22.37 days, with severe and major injuries accounting for 11.21% and 10.28% of all injuries, respectively. Goalkeepers had the highest average TRP of 36.15 days. Recurring injuries had a higher average TRP of 33.44 days compared to nonrecurring injuries, which had an average TRP of 20.43 days. Surgically treated injuries had the highest average TRP of 112.5 days. ConclusionShoulder injuries in the professional football scenario are of great concern due to the high recurrence rate and need for surgical treatment, which will lead to a long TRP. These findings emphasize the need to implement prevention protocols and effective treatments to reduce the consequences of such injuries, which are usually underestimated in this sport.

Alteration in ACL loading after total and partial medial meniscectomy

Anterior cruciate ligament (ACL) injuries are often caused by high impact loadings during competitive sports but may also happen during regular daily activities due to tissue degeneration or altered mechanics after a previous knee injury or surgery such as meniscectomy. Most existing research on ACL injury has focused on impact loading scenarios or the consequence of ACL injury on meniscus. The objective of the present study was to investigate the effects of varying degrees of medial meniscectomy on the mechanics of intact ACL by performing a poromechanical finite element analysis under moderate creep loadings. Four clinical scenarios with 25%, 50%, 75% and total medial meniscectomy were compared with the intact knee finite element model. Our results suggested that different medial meniscal resections may increase, at different extents, the knee laxity and peak tensile stress in the ACL, potentially leading to collagen fiber fatigue tearing and altered mechanobiology under normal joint loadings. Interestingly, the ACL stress actually increased during early knee creep (~ 3 min) before it reached an equilibrium. In addition, meniscectomy accelerated ACL stress reduction during knee creep, transferred more loading to tibial cartilage, increased contact pressure, and shifted the contact center posteriorly. This study may contribute to a better understanding of the interaction of meniscectomy and ACL integrity during daily loadings.

Experience in use of full-layer skin autografts in treatment of post-burn cicatricial deformities

Despite technologically advanced approaches to the treatment of patients with thermal lesions of II–III degree, a high percentage of development of cicatricial deformities and contractures with the formation of functionally significant disorders remains. According to a number of authors, post- burn cicatricial deformities and contractures develop in 45.0 %–76.5 %. In order to eliminate cicatricial deformities and contractures, various types of skin grafting are used in clinical practice, which depends both on the localization of scars, the state of surrounding and underlying tissues, the presence of donor sites, and on the goals and expected result of the planned surgical intervention. Considering these aspects and possibilities, the question of choosing the method of surgical treatment of cicatricial deformities and contractures of functional and aesthetically significant areas remains debatable. An analysis was made of the results of treatment of 603 patients who underwent reconstructive and restorative operations. In order to eliminate cicatricial contractures, accompanied by functional disorders in the area of the joints, as well as in aesthetically significant areas, reconstructive operations were performed, mainly using full-thickness autografts. Analysis of the results of surgical treatment of cicatricial contractures of functional and aesthetically significant areas using free autodermoplasty with full-thickness grafts showed its effectiveness, as it made it possible not only to eliminate functional disorders in the operated area and restore the mechanics of movements, but also to minimize the risk of recurrence of cicatricial contractures – repeated reconstructive operations amounted to no more than 1.5 % of all operated patients. Conclusions. In order to eliminate cicatricial contractures, as well as to improve the aesthetic results of treatment in patients with the consequences of a burn injury, it is most advisable to perform autodermoplasty with full-layer autografts in functional and aesthetically significant areas.

The relationship between cognitive functioning and syndromic characteristics and neuroimaging changes in patients with different types of encephalopathies

Cognitive impairment can be a consequence of direct and indirect brain injury, hypoxia, edema, metabolic disorders, neurodegenerative processes, metabolic encephalopathies, electrolyte abnormalities, organ failure, the effects of pesticides, toxins, drugs, and infectious processes. The results are presented from the study on correlations between cognitive functioning and syndromic characteristics and neuroimaging changes in patients with chronic post-traumatic (CTE), chronic vascular (CVE), chronic alcohol-induced (CAIE) and post-infectious (PIE) encephalopathies. The data of 520 medical records of patients with CTE (n = 145), CVE (n = 145), CAIE (n = 102) and PIE (n = 128) were analyzed. Neuroimaging was performed using multislice computed tomography. Cognitive functions were examined using the Montreal Cognitive Assessment. Statistical analysis of data was carried out with the help of computer software Microsoft Excel and Statistica 13.0. There was a probable relationship between cognitive functioning and extrapyramidal syndrome in patients with CVE; cognitive impairment and emotional lability disorder in patients with CAIE; cephalalgia syndrome, motor disorder syndrome and cerebellar ataxia syndrome in patients with PIE. In participants with CTE and CAIE, there was a significant correlation between cognitive functioning and ventricular enlargement; in patients with PIE — between cognitive functioning and the enlargement of the subarachnoid spaces.

Assessment of Agent Avoidance Behavior in the Face of Fire Hazards

ABSTRACT An assessment approach is proposed to assess the injury consequences of evacuation in the face of fire hazards, taking into account the spatial-temporal distribution of fire hazards and the time-varying location of agents. In this study, the diffusion process of fire hazards is simulated first using the fire dynamics simulator (FDS version 6.7.7) software, and an assessment approach is proposed, when fire hazards including toxic gases, thermal radiation, high temperature, and extinction coefficient are considered. Then, a novel fire avoidance model based on the modified social force model is proposed, and the impacts of heat release rate and soot yield on the injury consequences are discussed. The results demonstrate that an increase in heat release rate leads to an increase in the temperature and radiation values near the fire source, which directly raises the injury consequences. Soot yield primarily affects environmental visibility and thus the agent’s evacuation speed, which in turn affects the exposure time in fire hazards and injury consequences. Finally, the proposed fire avoidance model is compared with the existing radiation repulsive force model and the interaction force model between agents and fire. It is concluded that the proposed fire avoidance model can present a more reasonable fire avoidance behavior with significantly less cumulative injuries than the existing fire avoidance models.

Phenotyping Depression After Mild Traumatic Brain Injury: Evaluating the Impact of Multiple Injury, Gender, and Injury Context.

The chronic mental health consequences of mild traumatic brain injury (TBI) are a leading cause of disability. This is surprising given the expectation of significant recovery after mild TBI, which suggests that other injury-related factors may contribute to long-term adverse outcomes. The objective of this study was to determine how number of prior injuries, gender, and environment/context of injury may contribute to depressive symptoms after mild TBI among deployed United States service members and veterans (SMVs). Data from the Long-term Impact of Military-Relevant Brain Injury Consortium Prospective Longitudinal Study was used to assess TBI injury characteristics and depression scores previously measured on the Patient Health Questionnaire-9 (PHQ-9) among a sample of 1456 deployed SMVs. Clinical diagnosis of mild TBI was defined via a multi-step process centered on a structured face-to-face interview. Logistical and linear regressions stratified by gender and environment of injury were used to model depressive symptoms controlling for sociodemographic and combat deployment covariates. Relative to controls with no history of mild TBI (n = 280), the odds ratios (OR) for moderate/severe depression (PHQ-9 ≥ 10) were higher for SMVs with one mild TBI (n = 358) OR: 1.62 (95% confidence interval [CI] 1.09-2.40, p = 0.016) and two or more mild TBIs (n = 818) OR: 1.84 (95% CI 1.31-2.59, p < 0.001). Risk differences across groups were assessed in stratified linear models, which found that depression symptoms were elevated in those with a history of multiple mild TBIs compared with those who had a single mild TBI (p < 0.001). Combat deployment-related injuries were also associated with higher depression scores than injuries occurring in non-combat or civilian settings (p < 0.001). Increased rates of depression after mild TBI persisted in the absence of post-traumatic stress disorder. Both men and women SMVs separately exhibited significantly increased depressive symptom scores if they had had combat-related mild TBI. These results suggest that contextual information, gender, and prior injury history may influence long-term mental health outcomes among SMVs with mild TBI exposure.

Circulating microRNA miR-425-5p Associated with Brain White Matter Lesions and Inflammatory Processes.

White matter lesions (WML) emerge as a consequence of vascular injuries in the brain. While they are commonly observed in aging, associations have been established with neurodegenerative and neurological disorders such as dementia or stroke. Despite substantial research efforts, biological mechanisms are incomplete and biomarkers indicating WMLs are lacking. Utilizing data from the population-based Study of Health in Pomerania (SHIP), our objective was to identify plasma-circulating micro-RNAs (miRNAs) associated with WMLs, thus providing a foundation for a comprehensive biological model and further research. In linear regression models, direct association and moderating factors were analyzed. In 648 individuals, we identified hsa-miR-425-5p as directly associated with WMLs. In subsequent analyses, hsa-miR-425-5p was found to regulate various genes associated with WMLs with particular emphasis on the SH3PXD2A gene. Furthermore, miR-425-5p was found to be involved in immunological processes. In addition, noteworthy miRNAs associated with WMLs were identified, primarily moderated by the factors of sex or smoking status. All identified miRNAs exhibited a strong over-representation in neurodegenerative and neurological diseases. We introduced hsa-miR-425-5p as a promising candidate in WML research probably involved in immunological processes. Mir-425-5p holds the potential as a biomarker of WMLs, shedding light on potential mechanisms and pathways in vascular dementia.

Diffusion tensor imaging and plasma immunological biomarker panel in a rat traumatic brain injury (TBI) model and in human clinical TBI.

Neuroinflammatory reactions play a significant role in the pathology and long-term consequences of traumatic brain injury (TBI) and may mediate salutogenic processes that white matter integrity. This study aimed to investigate the relationship between inflammatory markers and white matter integrity following TBI in both a rat TBI model and clinical TBI cases. In the rat model, blood samples were collected following a controlled cortical impact (CCI) to assess a panel of inflammatory markers; MR-based diffusion tensor imaging (DTI) was employed to evaluate white matter integrity 60 days post-injury. 15 clinical TBI patients were similarly assessed for a panel of inflammatory markers and DTI post-intensive care unit discharge. Blood samples from healthy controls were used for comparison of the inflammatory markers. Time-dependent elevations in immunological markers were observed in TBI rats, with a correlation to preserved fractional anisotropy (FA) in white matter. Specifically, TBI-induced increased plasma levels of IL-1β, IL-6, G-CSF, CCL3, CCL5, and TNF-α were associated with higher white matter integrity, as measured by FA. Clinical cases had similar findings: elevated inflammatory markers (relative to controls) were associated with preservation of FA in vulnerable white matter regions. Inflammatory markers in post-TBI plasma samples are ambivalent with respect to prediction of favourable outcome versus a progression to more pervasive pathology and morbidity.

Potential role of hippocampal neurogenesis in spinal cord injury induced post-trauma depression.

It has been reported both in clinic and rodent models that beyond spinal cord injury directly induced symptoms, such as paralysis, neuropathic pain, bladder/bowel dysfunction, and loss of sexual function, there are a variety of secondary complications, including memory loss, cognitive decline, depression, and Alzheimer's disease. The large-scale longitudinal population-based studies indicate that post-trauma depression is highly prevalent in spinal cord injury patients. Yet, few basic studies have been conducted to address the potential molecular mechanisms. One of possible factors underlying the depression is the reduction of adult hippocampal neurogenesis which may come from less physical activity, social isolation, chronic pain, and elevated neuroinflammation after spinal cord injury. However, there is no clear consensus yet. In this review, we will first summarize the alteration of hippocampal neurogenesis post-spinal cord injury. Then, we will discuss possible mechanisms underlie this important spinal cord injury consequence. Finally, we will outline the potential therapeutic options aimed at enhancing hippocampal neurogenesis to ameliorate depression.

The Effect of Liraglutide on Axon Regeneration and Functional Recovery after Peripheral Nerve Lesion.

Peripheral nerve injuries inflict severe consequences, necessitating innovative therapeutic strategies. This study investigates the potential of liraglutide, a glucagon-like peptide-1 receptor agonist, in mitigating the consequences of peripheral nerve injury. The existing treatment methods for such injuries underscore the importance of ongoing translational research efforts. Thirty adult Wistar rats underwent sciatic nerve dissection and repair surgery. The nerves were surgically transected using micro scissors at a precise location located 1.5 cm proximal to the trifurcation site. The study included a control group and two experimental groups, one treated with saline (placebo group) and the other with liraglutide (experimental group) for 12 weeks. Motor function, electromyography (EMG), and biochemical and histopathological analyses were performed after 12 weeks of treatment. Electrophysiological assessments revealed that liraglutide improved the compound muscle action potential (CMAP) amplitude and motor function compared to the saline-treated group. Histological and immunohistochemical analyses demonstrated increased NGF expression, total axon number, and diameter and reduced fibrosis in the liraglutide group. Biochemical analyses illustrated liraglutide's antioxidative properties, evidenced by reduced malondialdehyde (MDA) levels. Galectin-3 levels were suppressed and GDF-11 levels were modulated by liraglutide, indicating anti-inflammatory and anti-apoptotic effects. Liraglutide is a promising therapeutic intervention for peripheral nerve injuries, promoting functional recovery and histopathological improvement. Its multifaceted positive impact, beyond glycemic control, suggests constructive effects on the acute and chronic inflammatory processes associated with peripheral neuropathy. These findings warrant further research to elucidate molecular mechanisms and facilitate clinical translation. The study contributes valuable insights to the growing understanding of GLP-1 receptor agonists' neuroprotective properties in the context of peripheral nerve injuries.

The results of the corrective rehabilitation program on the gait of amateur athletes with long-term consequences of brain injury

Aim: To study the results of the quality of life, the state of vestibular disorders and the nature of walking of amateur athletes with the consequences of a combat craniocerebral injury after rehabilitation treatment according to a correctional program. Materials and Methods: The study was conducted on the basis of the Ukrainian Scientific Research Institute of Prosthetics in Kharkov. Under observation were 38 men aged 25-42 years with long-term consequences of a closed craniocerebral injury in the late long-term period. In all patients, complications after TBI were persistent headache, decreased muscle strength in the lower extremities, impaired coordination and balance, and walking patterns. All patients were involved in amateur sports before injury. The following research methods were used during the examination: visual analogue pain scale (VAS), Lovett manual muscle test, Bohannon test, ≪Timed Up and Go test≫. Results: All patients were randomly divided into two groups. Patients Gr.1 (n=20) were trained according to the developed program, which included training according to the PNF method, kinesiotherapy, classes on the C-mill sensory treadmill and the Hunova computer device, segmental reflex massage. Patients Gr. 2 (n=18) underwent a course of physical rehabilitation according to the generally accepted methodology of the Ministry of Health of Ukraine. After working with patients according to the developed correction and rehabilitation program, the following dynamics were observed: the quality of life on the VAS scale in Gr.1 patients had a statistically significant difference (p&lt;0.05) compared to the primary indicator. The dynamics of the Lovett manual muscle test indicated an increase in the muscle strength of the extensor and flexor muscle groups of the lower extremities, the dynamics of the balance indicator in the standing position behind Bohann in all Gr.1 patients and acquired statistical significance (p&lt;0,05). According to the test “Timed Up and Go” patients Gr.1 approached the standard value (p&lt;0,05). In all patients of Gr. 2, the studied characteristics had a positive trend (p&gt;0,05). Conclusions: Individual selection of physical exercises, development of correctional and rehabilitation programs, multidisciplinary approach has a positive impact on changes in the functional state of amateur athletes, quality of life and contributes to the return to an active social life.

Blockade of Piezo2 Pathway Attenuates Inflammatory and Neuropathic Pain in the Orofacial Area.

Although previous studies suggest that Piezo2 regulates chronic pain in the orofacial area, few studies have reported the direct evidence of Piezo2's involvement in inflammatory and neuropathic pain in the orofacial region. In this study, we used male Sprague Dawley rats to investigate the role of the Piezo2 pathway in the development of inflammatory and neuropathic pain. The present study used interleukin (IL)-1β-induced pronociception as an inflammatory pain model. Subcutaneous injection of IL-1β produced significant mechanical allodynia and thermal hyperalgesia. Subcutaneous injection of a Piezo2 inhibitor significantly blocked mechanical allodynia and thermal hyperalgesia induced by subcutaneously injected IL-1β. Furthermore, the present study also used a neuropathic pain model caused by the misplacement of a dental implant, leading to notable mechanical allodynia as a consequence of inferior alveolar nerve injury. Western blot analysis revealed increased levels of Piezo2 in the trigeminal ganglion and the trigeminal subnucleus caudalis after inferior alveolar nerve injury. Furthermore, subcutaneous and intracisternal injections of a Piezo2 inhibitor blocked neuropathic mechanical allodynia. These results suggest that the Piezo2 pathway plays a critical role in the development of inflammatory and neuropathic pain in the orofacial area. Therefore, blocking the Piezo2 pathway could be the foundation for developing new therapeutic strategies to treat orofacial pain conditions.

Penile Strangulation: Analysis of Postextrication Follow-Up, Sequelae, and a Review of Literature.

Numerous case reports exist on penile strangulation injuries and extrication methods; however, the care and long-term consequences of penile strangulation injuries have been under-reported. Our aim is to investigate the long-term outcomes and sequalae following penile strangulation injuries. The PubMed Medline database was searched using the keyword string "penile strangulation," "penis strangulation," and "constriction" for all studies reporting outcomes of published penile strangulation injuries. Articles were evaluated for follow-up after strangulation injury, strangulating agent, extricating agent, and sequelae of injury. Fifty-six studies resulted with reports of 100 cases of penile strangulation and extrication from January 2000 to December 2019. The mean patient age was 41 (range: 3-86) years. Twenty-four (24/100) cases reported sequalae following extrication. Follow-up ranged from 2 weeks to 7 years with median follow-up time in the 7- to 12-month grouping. Metal rings comprised 36% (36/100) of strangulation agents and 50% of reported incidents were attributed to sexual activity. To our knowledge, this is the only study focusing on long-term outcomes after penile strangulation. This review provides a summary of 56 studies that document penile strangulation injuries over the last 20 years. Although a wide array of penile strangulation injuries have been documented in the literature, reports lack secondary management and long-term outcomes after removal of the strangulation device. We recommend that providers report long-term penile strangulation outcomes for future urologic evaluations after extrication.

ТРАВМА НОГТЕВОГО КОМПЛЕКСА: СОВРЕМЕННЫЙ ВЗГЛЯД НА ПРОБЛЕМУ ОКАЗАНИЯ МЕДИЦИНСКОЙ ПОМОЩИ

Despite the fact that the first decade of the XXI century was proclaimed by the World Health Organization as the decade of bone and joint treatment, defining the prevention and treatment of limb injuries as one of the five priority problems of musculoskeletal diseases, there is still no developed generally accepted algorithm for the management of patients with nail phalanx injuries, and the opinions of specialists are often diametrically divergent. Trauma to the distal phalanx of the fingers is one of the most common hand injuries in patients seeking emergency medical care, regardless of gender, age, or occupation. The consequences of nail phalangeal injuries worsen the aesthetic appearance of the hand, reduce the ability to work, and sometimes may even lead to a change in the patients' occupation. When nail complex trauma is combined with a distal phalanx fracture, it is necessary not only to restore the integrity of the nail bed, but also to stabilize the bone fragments. An important point in such situations is the use of a nail plate to temporarily cover the restored nail bed. Firstly, it serves as a stabilizing element for the reponated phalangeal fragments. Secondly, its use leads to a decrease in the percentage of scar formation in the nail bed. During the study, in 39 (37 patients, 80.4%) cases we found an excellent, in 7 (3 patients, 6.5%) – good and in 8 (6 patients, 13.1%) – satisfactory result of treatment. As a result of our study, we have proved that temporary covering of the nail bed with a utilized nail plate or artificial nail plate graft: a) reduces pain during the subsequent stage dressings at the outpatient stage; b) promotes normal growth of a new nail plate; c) accelerates the healing process, as traumatization of the nail bed is minimized; d) the nail plate acts as a natural splint, due to which, in most cases, no additional external fixation is required.

Cognitive impairment in post-traumatic stress disorder

Post-traumatic stress disorder (PTSD) is a common mental health disorder, with an incidence of up to 12.5% among primary care patients. Most often, PTSD is detected in combat veterans, victims of terrorist attacks and terror, but it can also be a consequence of traumatic brain injury and medical interventions. Impaired cognitive functioning is a key feature of PTSD, including attention deficits and reduced processing speed, executive dysfunction, and impairments in verbal learning and memory. Cognitive impairments in PTSD are significantly persistent and are largely similar in nature to neuropsychological impairments in neurodegenerative pathology. Possible pathogenetic mechanisms underlying PTSD are the development of neuroinflammation, oxidative stress and decreased production of neurotrophic factors. One of the promising areas of treatment is the use of Cerebrolysin, which has powerful neurotrophic and anti-inflammatory activity.

International classification of functioning, disability and health with long-term consequences of cranio-brain injury.

Aim: To describe health status and related functioning of patients with different severity of traumatic brain injury (TBI) in past medical history in Ukraine and determining the feasibility of using the International Classification of Functioning, Disability and Health (ICF) Brief Core Set for TBI. Materials and Methods: A total of 102 patients, who were treated in the neurological department of Dnipropetrovsk regional clinical hospital and State Institution ≪Ukrainian State Scientific Research Institute of Medical and Social Problems of Disability of Health Ministry of Ukraine≫, had been examined. Patients were divided into three groups: mild, moderate and severe TBI in past history and evaluated using ICF Brief Core Set for TBI. Results: Тhe most common problems in the functioning and health of patients in remote period of TBI, along with the influencing factors have been identified in the study. The most frequent categories from ≪Body Functions≫ and ≪Activity and Participation≫ sections in which patients had alterations were: memory functions, emotional functions, sensation of pain, functions of attention, brain structure, complex interpersonal interactions, family relationships. The increase in the amount and severity of disturbances with increasing severity of TBI had been established in all categories, except complex interpersonal interactions and family relationships. Conclusions: Patients of all groups identified the family and close relatives, healthcare service and social welfare services, as the most frequent relieving factors of life activity. The use of the ICF Brief Core Set for assessing the subjects with TBI in past history provides a convenient procedure to standardize and structure functioning description. Information collected by the ICF Brief Core Set may be used for different purposes: clinical assessment, administration of medical services, planning and implementation of rehabilitation and evaluation of results, in scientific research, reports and health care statistics.

Hydrogen sulfide balneotherapy in comprehensive sanatorium-resort treatment of post-burn scars in children

To analyze the results of hydrogen sulfide balneotherapy in children with consequences of thermal injury. A single-center observational retrospective non-controlled study was carried out, in which sanatorium-resort treatment concerning post-burn scars in 812 children aged 5-17 years was analyzed. Hydrogen sulfide balneotherapy was prescribed to patients depending on the age in mild (5-6 years) or moderate-to-high (7-17 years) exposure modes. The imported hydrogen sulfide mineral water from the T-2000 well of the Matsesta field with the H2S total concentration of 410-420 mg/l was used for treatment. The applications were performed to children alternate days, 8 procedures of balneotherapy per course. Lightening of the affected areas of the skin, reduction of the sensation of contraction and tension of the scars, which became softer, more elastic and more mobile with regard to the subjacent tissues have been noted in patients after the course of balneotherapy. The head mobility increased after applications in the presence of scars. The large joints' range of motion grew up. In addition, an increase in the mobility of the fingers of wrists and feet, a decrease in the stiffness of movements, increase or recovery of the affected skin's tactile sensitivity have been observed. Children well tolerated procedures, adverse events were seen in 0.7% of cases in the form of mild reactions at the beginning of the applications' course, namely of balneological (0.6%) and toxico-allergic (0.1%) nature. Hydrogen sulfide balneotherapy in combination with rehabilitation exercises and other sanatorium-resort factors is an effective mean of post-burn scars correction in children.

Prevalence of Sports Injuries Among School Student-Athletes and Their Effects on the Mental and Physical Health

Background: Regular exercise is beneficial for children and teenagers in terms of physical and mental health, but it is crucial to acknowledge the potential for injuries and the lack of extensive research on the prevalence and consequences of sports-related injuries in this age group. Objectives: This study aims to investigate the occurrence of sports injuries and assess how they may affect students' mental and physical well-being. Methods: The current study was cross-sectional research conducted in Hamedan City from 1401 to 1402. The statistical population of this study consisted of students who participated in team sports. A total of 153 students, with an average age of 14.1 ± 2.8, were selected as the study population. The quality of life was assessed using the SF36 scale, while physical and mental health were evaluated using the PROMIS-2 scales. The collected data were analyzed using SPSS version 21 software and the independent t-test statistical method, with a significance level set at 0.05. Results: The research results have shown that 24.2% of student-athletes in Hamedan City suffer from sports injuries in at least one part of their body. The areas that most commonly affected were the feet and toes (16.2%), ankles (13.5%), and knees (10.8%). Furthermore, the findings from the research indicate that student-athletes with a previous history of sports injuries had a significantly lower average quality of life, physical health, social functioning, and pain interference compared to those who had not experienced such injuries (P &lt; 0.05). Conclusions: Sports injuries are common among student-athletes who participate in team sports, and they can significantly affect both their physical and social well-being. Such injuries can have a detrimental impact on the daily lives and social interactions of adolescent athletes. Therefore, health professionals must be fully aware of these repercussions and make them a key focus when managing sports injuries.

A systematic review of programs and interventions for reduction of sickness absence in nursing staff with work-related musculoskeletal disorders.

Negative consequences of musculoskeletal pain and injuries on the nurses' health and well-being can increase job dissatisfaction and impose high costs on healthcare centers due to lost workdays and compensation claims. This study aimed to identify policies, programs, and interventions that might be effective in the prevention and reduction of sickness absence and improvement of work outcomes in nursing staff with these problems. The systematic review was conducted according to the preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines. Electronic databases were searched up to November 9-23, 2022. The keywords "musculoskeletal disorders", "nurse", "return to work", "sickness absence", and "sick leave" and their equivalents were combined using Boolean operators OR/AND. Reference lists of eligible literatures were also screened to identify related studies. In this study, a total of 3365 records were retrieved. After two rounds of screening, 15 studies were selected for qualitative synthesis. These studies included seven randomized controlled trial, five pre-post studies, two cohort, and one cross-sectional. Six types of interventions identified including back college, early workplace-based intervention, physical activity/training, psychosocial education, multifaceted intervention, and ergonomics program. There is insufficient evidence to identify effective interventions in preventing and reducing sickness absence, and improvement of work outcomes in nursing personnel with work-related musculoskeletal disorders. Numerous factors affected the occurrence of such disorders, and their consequences, therefore comprehensive strategy tailored to the injured person's needs should be considered.
