Consensus Statement on the Management of Nonthrombotic Iliac Vein Lesions From the VIVA Foundation, the American Venous Forum, and the American Vein and Lymphatic Society.

A nonthrombotic iliac vein lesion is defined as the extrinsic compression of the iliac vein. Symptoms of lower extremity chronic venous insufficiency or pelvic venous disease can develop secondary to nonthrombotic iliac vein lesion. Anatomic compression has been observed in both symptomatic and asymptomatic patients. Causative factors that lead to symptomatic manifestations remain unclear. To provide guidance for providers treating patients with nonthrombotic iliac vein lesion, the VIVA Foundation convened a multidisciplinary group of leaders in venous disease management with representatives from the American Venous Forum and the American Vein and Lymphatic Society. Consensus statements regarding nonthrombotic iliac vein lesions were drafted by the participants to address patient selection, imaging for diagnosis, technical considerations for stent placement, postprocedure management, and future research/educational needs.

Reticulated Retinoic Acid Synthesis is Implicated in the Pathogenesis of Dry Eye in Aqp5 Deficiency Mice.

Abnormalities in aquaporins are implicated in the pathological progression of dry eye syndrome. Retinoic acid (RA) regulates cellular proliferation, differentiation, and apoptosis in the cornea, thereby being associated with dry eye disease (DED). The objective of this study is to explore the underlying mechanisms responsible for RA metabolic abnormalities in corneas lacking aquaporin 5 (AQP5). Dry eye (DE) models were induced via subcutaneous scopolamine hydrobromide. Aqp5 knockout (Aqp5-/-) mice and DE mice were utilized to assess corneal epithelial alterations. Tear secretion, goblet cell counts, and corneal punctate defects were evaluated. The impact of Aqp5 on RA-related enzymes and receptors was investigated using pharmacological RA or SR (A JunB inhibitor), a transcription factor JunB inhibitor, treatment in mouse corneal epithelial cells (CECs), or human corneal epithelial cells (HCECs). The HCECs and NaCl-treated HCECs underwent quantitative real-time PCR (qRT-PCR), immunofluorescent, Western blot, and TUNEL assays. The regulation of transcription factor JunB on Aldh1a1 was explored via ChIP-PCR. Aqp5 and Aldh1a1 were reduced in both CECs of DE mice and NaCl-induced HCECs. Aqp5-/- mice exhibited DE phenotype and reduced Aldh1a1. RA treatment reduced apoptosis, promoted proliferation, and improved the DE phenotype in Aqp5-/- mice. JunB enrichment in the Aldh1a1 promoter was identified by ChIP-PCR. SR significantly increased Aldh1a1 expression, Ki67, and ΔNp63-positive cells, and decreased TUNEL-positive cells in CECs and HCECs. Our findings demonstrated the downregulation of Aqp5 expression and aberrant RA metabolism in DE conditions. Knockout of Aqp5 resulted in reduced production of RA through activation of JunB, subsequently leading to the manifestation of DE symptoms.

Data-independent LC-MS/MS analysis of ME/CFS plasma reveals a dysregulated coagulation system, endothelial dysfunction, downregulation of complement machinery

Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is a debilitating chronic condition that is characterized by unresolved fatigue, post-exertion symptom exacerbation (PESE), cognitive dysfunction, orthostatic intolerance, and other symptoms. ME/CFS lacks established clinical biomarkers and requires further elucidation of disease mechanisms. A growing number of studies demonstrate signs of hematological and cardiovascular pathology in ME/CFS cohorts, including hyperactivated platelets, endothelial dysfunction, vascular dysregulation, and anomalous clotting processes. To build on these findings, and to identify potential biomarkers that can be related to pathophysiology, we measured differences in protein expression in platelet-poor plasma (PPP) samples from 15 ME/CFS study participants and 10 controls not previously infected with SARS-CoV-2, using DIA LC-MS/MS. We identified 24 proteins that are significantly increased in the ME/CFS group compared to the controls, and 21 proteins that are significantly downregulated. Proteins related to clotting processes – thrombospondin-1 (important in platelet activation), platelet factor 4, and protein S – were differentially expressed in the ME/CFS group, suggestive of a dysregulated coagulation system and abnormal endothelial function. Complement machinery was also significantly downregulated, including C9 which forms part of the membrane attack complex. Additionally, we identified a significant upregulation of lactotransferrin, protein S100-A9, and an immunoglobulin variant. The findings from this experiment further implicate the coagulation and immune system in ME/CFS, and bring to attention the pathology of or imposed on the endothelium. This study highlights potential systems and proteins that require further research with regards to their contribution to the pathogenesis of ME/CFS, symptom manifestation, and biomarker potential, and also gives insight into the hematological and cardiovascular risk for ME/CFS individuals affected by diabetes mellitus.Graphical abstract

Altered white matter connectivity of ventral language networks in autism spectrum disorder: An automated fiber quantification analysis with multi-site datasets

Comprehension and pragmatic deficits are prevalent in autism spectrum disorder (ASD) and are potentially linked to altered connectivity in the ventral language networks. However, previous magnetic resonance imaging studies have not sufficiently explored the microstructural abnormalities in the ventral fiber tracts underlying comprehension dysfunction in ASD. Additionally, the precise locations of white matter (WM) changes in the long tracts of patients with ASD remain poorly understood. In the current study, we applied the automated fiber-tract quantification (AFQ) method to investigate the fine-grained WM properties of the ventral language pathway and their relationships with comprehension and symptom manifestation in ASD. The analysis included diffusion/T1 weighted imaging data of 83 individuals with ASD and 83 age-matched typically developing (TD) controls. Case-control comparisons were performed on the diffusion metrics of the ventral tracts at both the global and point-wise levels. We also explored correlations between diffusion metrics, comprehension performance, and ASD traits, and conducted subgroup analyses based on age range to examine developmental moderating effects. Individuals with ASD exhibited remarkable hypoconnectivity in the ventral tracts, particularly in the temporal portions of the left inferior longitudinal fasciculus (ILF) and the inferior fronto-occipital fasciculus (IFOF). These WM abnormalities were associated with poor comprehension and more severe ASD symptoms. Furthermore, WM alterations in the ventral tract and their correlation with comprehension dysfunction were more prominent in younger children with ASD than in adolescents. These findings indicate that WM disruptions in the temporal portions of the left ILF/IFOF are most notable in ASD, potentially constituting the core neurological underpinnings of comprehension and communication deficits in autism. Moreover, impaired WM connectivity and comprehension ability in patients with ASD appear to improve with age.

Consequences of ionizing radiation exposure to the cardiovascular system.

Ionizing radiation is widely used in various industrial and medical applications, resulting in increased exposure for certain populations. Lessons from radiation accidents and occupational exposure have highlighted the cardiovascular and cerebrovascular risks associated with radiation exposure. In addition, radiation therapy for cancer has been linked to numerous cardiovascular complications, depending on the distribution of the dose by volume in the heart and other relevant target tissues in the circulatory system. The manifestation of symptoms is influenced by numerous factors, and distinct cardiac complications have previously been observed in different groups of patients with cancer undergoing radiation therapy. However, in contemporary radiation therapy, advances in treatment planning with conformal radiation delivery have markedly reduced the mean heart dose and volume of exposure, and these variables are therefore no longer sole surrogates for predicting the risk of specific types of heart disease. Nevertheless, certain cardiac substructures remain vulnerable to radiation exposure, necessitating close monitoring. In this Review, we provide a comprehensive overview of the consequences of radiation exposure on the cardiovascular system, drawing insights from various cohorts exposed to uniform, whole-body radiation or to partial-body irradiation, and identify potential risk modifiers in the development of radiation-associated cardiovascular disease.

Endometriosis and Adenomyosis: Modern Concepts of Their Clinical Outcomes, Treatment, and Management.

Endometriosis and adenomyosis are complex gynecological conditions characterized by diverse clinical presentations, including superficial peritoneal endometriosis (SPE), ovarian endometrioma (OMA), and deep infiltrating endometriosis (DIE). The hallmark features of these pathologies involve the manifestation of pain symptoms and infertility, and approximately 30% of patients are asymptomatic. Despite ongoing research, definitive treatments for these conditions remain elusive, and clinical management primarily revolves around medical or surgical interventions. Recent advancements in our understanding of the efficacy of various treatment modalities, including medical therapy and surgical interventions, have provided clinicians with valuable insights into pain relief and fertility preservation. This review aims to provide an updated overview of the latest literature on clinical outcomes, treatment options, and management strategies for different types of endometriosis. By synthesizing the newest available data, this review seeks to inform clinicians and guide decision making based on factors such as patients' symptom severity, childbearing desire, and overall health.

Urachal abnormalities in the adult population. Is physical activity involved in clinical manifestation Literature review

Introduction The urachal anomaly is a developmental defect, a remnant of fetal life consisting of a patent connection between the dome of the urinary bladder and the umbilicus. It can take various forms. Most commonly it occurs in males, very rarely in adults. The main symptoms associated with this condition are: foul-smelling discharge from the umbilicus, abdominal pain, hematuria, or recurrent urinary tract infections. Imaging plays a crucial role in the diagnosis of the persistent urachus. Aim of the studyThe aim of the study is to sentize doctors’ attention that patent urachus is the rare but possible diagnosis of acute abdomen pain in adults population and bring the proceedings.Materials and methods: An analysis of papers avaliable on Pubmed and Google Scholar was performed. The following key words: urachal anomalies, adults, abdomen pain, urachal remnants, urachal carcinoma were used.Results:Lately, thanks to modern precise imaging diagnostics, more valuable studies have been conducted, allowing to characterize residual ureteral remnants, which are most often asymptomatic in population of adults. However the manifestation of symptoms is mostly associated with infection of the mentioned area or a tumor transformation. There are at least two case reports which report that infection of urachal remnants could manifestate after intensive physical activity. It is worth in-depth interviewing. Studies indicate the necessity of surgical removal of persistent urachal anomalies, as they carry the risk of rapid growth and unfavorable prognosis of cancerous spread.

White matter microstructure alterations of the posterior limb of internal capsule in first-episode drug naive schizophrenia patients

ObjectivesPrevious studies have shown that microstructural alterations in white matter (WM) could contribute to the symptom manifestation and support the dysconnectivity hypothesis in schizophrenia patients. These alterations were pervasive, non-specific, and reported inconsistently across the literature. This study aimed to specifically investigate the microstructure alterations of the posterior limb of the internal capsule (PLIC) in first-episode, drug-naive schizophrenia patients. Utilizing a multicompartmental biophysical model, we further explored the correlation between these alterations and syndrome scale scores. MethodsThirty-two individuals with first-episode, drug-naive schizophrenia (FES) and thirty demographically matched healthy controls were enrolled. High-resolution multi-shell diffusion MRI data were collected, followed by the application of a three-compartment Neurite Orientation Dispersion and Density Imaging (NODDI) model to scrutinize the alterations in white matter microstructure. Changes in sensory and motor fibers within the PLIC were specifically focused on. Additionally, the correlation between these pathological changes and scores on the Positive and Negative Syndrome Scale (PANSS) was investigated. ResultsThe Neurite density index (NDI) in the left PLIC was significantly lower in FES patients compared to healthy individuals, and positively correlated with PANSS positive syndrome scores (r = 0.0379, p = 0.046). In the sensory component (left superior thalamic radiation within PLIC, STR_P), the NDI was significantly elevated (p < 0.0001). Conversely, the NDI in the motor component (left corticospinal tract within PLIC, CST_P) was reduced (p = 0.007) in FES patients compared to healthy individuals, and strongly correlated with PANSS positive syndrome scores (p < 0.020) and PANSS total scores (p < 0.045). Moreover, the NDI deviation of STR from total PLIC (fSTR_P) and NDI deviation in STR_P and CST_P compared to PLIC region (fPLIC) were significantly higher in FES patients than in healthy controls (p < 0.00001), with an area under the curve (AUC) of fPLIC reaching 0.872. ConclusionThe study’s findings provided new insights into the discrepancy of white matter microstructure changes associated with the sensory and motor fibers in the PLIC region in FES patients. These results contribute to the growing body of evidence suggesting that WM microstructural alterations play a critical role in schizophrenia pathophysiology.

Clinical Evaluation of Xpert Xpress SARS-CoV-2/Flu/RSV Combination Test in China

During influenza season, the influenza virus and respiratory syncytial virus (RSV) can cause severe respiratory infections. The clinical manifestation of symptoms caused by COVID-19, influenza virus and RSV are very similar.We conducted the performance characteristics of the Xpert Xpress SARS-CoV-2/Flu/RSV combined assay in China and came up with the detection results of the two detection methods are almost the same for all targets, and the consistency rate is close to 100%.This indicates that the assay is of great clinical value for distinguishing infections caused by these four viruses.

Perioperative Sleep Disturbance in Surgical Patients: A Concept Analysis.

To investigate and define the concept of perioperative sleep disturbance (PSD) among surgical patients, with the goal of aiding clinical practice and research. Walker and Avant's eight-step approach of concept analysis was applied. A systematic search of English literature was conducted in the following databases: PubMed, Web of Science, and CINAHL, with a time restriction from 2010 to August 2023. Based on the 54 eligible studies, the attributes of PSD in surgical patients were identified as individualized symptom manifestation, difficulty initiating and/or maintaining sleep, and altered sleep patterns. The antecedents included poor psychological state, inaccurate perception, surgery and/or anesthesia-related physiological changes, and environmental interference. PSD in surgical patients was found to result in physical discomfort, psychological disorder, impaired neurocognitive function, and prolonged recovery. A clearly defined and distinguishable concept of PSD in surgical patients was achieved through concept analysis, which provides a conceptual basis for future development in both clinical practice and related research.

Exploring functional and structural connectivity disruptions in spinocerebellar ataxia type 3: Insights from gradient analysis.

Spinocerebellar Ataxia Type 3 (SCA3) is a rare genetic ataxia that impacts the entire brain and is characterized as a neurodegenerative disorder affecting the neural network. This study explores how alterations in the functional hierarchy, connectivity, and structural changes within specific brain regions significantly contribute to the heterogeneity of symptom manifestations in patients with SCA3. We prospectively recruited 51 patients with SCA3 and 59 age-and sex-matched healthy controls. All participants underwent comprehensive multimodal neuroimaging and clinical assessments. In SCA3 patients, an innovative approach utilizing gradients in resting-state functional connectivity (FC) was employed to examine atypical patterns of hierarchical processing topology from sensorimotor to supramodal regions in the cerebellum and cerebrum. Coupling analyses of abnormal FC and structural connectivity among regions of interest (ROIs) in the brain were also performed to characterize connectivity alterations. Additionally, relationships between quantitative ROI values and clinical variables were explored. Patients with SCA3 exhibited either compression or expansion within the primary sensorimotor-to-supramodal gradient through four distinct calculation methods, along with disruptions in FC and structural connectivity coupling. A comprehensive correlation was identified between the altered gradients and the clinical manifestations observed in patients. Notably, altered fractional anisotropy values were not significantly correlated with clinical variables. Abnormal gradients and connectivity in the cerebellar and cerebral cortices in SCA3 patients may contribute to disrupted motor-to-supramodal functions. Moreover, these findings support the potential utility of FCG analysis as a biomarker for diagnosing SCA3 and assessing treatment efficacy.

Asymptomatic canine vector-borne diseases and diagnostic performance: Comparison between blood smears vs. conventional PCR

Across the globe, vector-borne diseases (VBD) are causes of health and economic concern, particularly for companion animals such as dogs and cats. The common clinical presentation ranges from subclinical to acute infection even a proportion with symptomatic manifestation. The diagnosis of asymptomatic animals with VBDs is quite challenging since veterinary practitioners do rely on presenting clinical signs to inform the choice of diagnostic plan. In Malaysia, blood smears (thin and thick) are employed in the diagnosis of VBDs such as babesiosis, anaplasmosis, theileriosis and trypanosomiasis. This method is readily available and inexpensive; however, the sensitivity and specificity are low as the diagnosis is strongly dependent on the experience of the examiner. Conventional polymerase chain reaction (PCR) on the other hand is used in larger veterinary clinics and hospitals in Malaysia and is only utilised when there is a suspicion of VBDs. This study attempts to compare the thin blood smear method and conventional PCR in the diagnosis of of Anaplasma phagocytophilum, A. platys, Babesia canis, B. gibsoni, Ehrlichia canis in dogs in Malaysia. Thirty clinically healthy dogs (17 males and 13 females) averaging 2 years of age were randomly selected from clinic walk-ins to screen for VBDs with both blood smear and conventional PCR. In general, the conventional PCR was 2.5 times more sensitive and specific than the blood smear in the detection of VBDs including Babesia canis, Babesia gibsoni and Ehrlichia canis in the asymptomatic sampled dogs. The detection rate for blood smears was 20% (6/30) in comparison with 50% (15/30). Therefore, it is imperative to conduct screenings for VBDs in dogs, even when they present as asymptomatic, in order to avert the oversight of potential health emergencies. Conventional PCR emerges as the recommended methodology for screening asymptomatic dogs for VBDs.

Characteristic features of brain development and remedial methods for autism spectrum disorders and attention deficit hyperactivity disorder: Review of current research

Introduction. Deep understanding of neurobiological processes in normal and abnormal children is crucially important for developing remedial procedures for mental development disorders and using inclusive learning methods. The purpose of this article is to summarize modern and most relevant information about the brain structure and functioning features in connection with disorders of neural structures, pathways and networks, as well as psychosocial and educational remedial methods for children with attention deficit hyperactivity disorder (ADHD) and autism spectrum disorders (ASD). Materials and Methods. The work is based on a comprehensive experimental research results analysis in the field of cognitive sciences and related areas affecting the issues of neurodivergent states. Research articles published between 2003 and 2024, mainly between 2021 and 2024, were used as materials. Results. Within the framework of this study, the authors identified key common and distinctive features of pathogenesis, epidemiology, and the neurobiological foundations of the ASD and ADHD development. Examples of disorders observed at the level of brain anatomical structures and functioning of individual neural networks are demonstrated. The spread of a symptomatic manifestations variety, concomitant disorders (comorbidity), the difficulty in differentiating the concepts of norm and pathology in a wide range of neurodivergent conditions are emphasized. Summarizing the data on various methods of therapy and treatment, the authors justified the key role of psychosocial adaptation within the framework of school education, which requires teachers’ understanding the peculiarities of mental development and techniques for interacting with neurodivergent children. Transmission of carefully selected information about the peculiarities of mental development to children seems to be relevant in order to help them understand their own problems and find solutions to them. These topics can be integrated into in the biology course given by appropriately prepared teachers. Conclusions. Rehabilitation and integration into society of children with ASD and ADHD is the main and practically the only way to solve the problem, requiring an understanding of the neurodevelopment peculiarities, conscious and tolerant attitude on the part of teachers, psychologists, parents and peers. The article is addressed to specialists in the field of psychology, special and inclusive education, pediatricians, educators, teachers, parents.

Мікробіологічні предиктори комплексного лікування інфекції акушерської хірургічної рани в породілей

Aim - based on the study of microbiological factors of the wound process, determine the effectiveness of treatment of obstetric surgical wound infection in women in labor when using drugs with sorption-detoxification and immunomodulatory properties. Materials and methods. Іn the work, microbiological studies were used to control the course of the wound process in 115 parturients with purulent wounds of the anterior abdominal wall after caesarean section and perineum after episiotomy, perineotomy, which, depending on the treatment method, were divided into groups: the Group I - 42 parturients with purulent wounds, which treated with organosilicon sorbent gentaxan; the Group II - 45 women in labor with purulent wounds, who were treated with organosilicon sorbent Gentaxan and immunomodulator Laferon; the Group III - 28 women in labor with purulent wounds, who were treated with traditional methods. The obtained results were processed by methods of statistical analysis. Results. Based on the analysis of microbiological studies, it was determined that the causative agent of purulent wounds in obstetric practice is opportunistic flora, among which S. epidermis. In 28.7%, inflammatory processes in the tissues of postoperative wounds arise under the influence of the symbiotic relationship of aerobic and anaerobic microorganisms. Complex treatment with gentaxan and laferon had an advantage over monotherapy with gentaxan and traditional methods, due to a more pronounced suppression of the pathogenic microflora of the wound and an increase in the number of microbes in its tissues in a shorter period of time, which accelerates the elimination of swelling and inflammation in the wound, the manifestation of symptoms that indicate complete healing biological cleaning of the wound, which, in turn, prevents contamination by hospital infection of the wounds of women in labor and further spread of the inflammatory process. Conclusions. The factor of wound infection is opportunistically pathogenic flora, which in 64.0% is isolated in aerobic and aerobic-anaerobic associations. Complex therapy of purulent wounds with drugs with sorption-detoxification and immunomodulatory properties increases the effectiveness of the treatment, due to the suppression of the pathogenic microflora of the wound and the increase of the number of microbes in its tissues in a shorter period of time, which prevents contamination by hospital infection of the wounds of women in labor and the further spread of the inflammatory process. The research was carried out in accordance with the principles of the Declaration of Helsinki. Research protocol approved by the Local Ethics Committee of the institution mentioned in the work. For conducting research informed consent of the parents was obtained from the women in labor. The authors declare no conflict of interest.

Dietary Supplementation with n-3 Polyunsaturated Fatty Acids Delays the Phenotypic Manifestation of Krabbe Disease and Partially Restores Lipid Mediator Production in the Brain-Study in a Mouse Model of the Disease.

Lipid mediators from fatty acid oxidation have been shown to be associated with the severity of Krabbe disease (KD), a disorder linked to mutations in the galactosylceramidase (GALC) gene. This study aims to investigate the effects of n-3 polyunsaturated fatty acid (PUFA) supplementation on KD traits and fatty acid metabolism using Twitcher (Tw) animals as a natural model for KD. Wild-type (Wt), heterozygous (Ht), and affected Tw animals were treated orally with 36 mg n-3 PUFAs/kg body weight/day from 10 to 35 days of life. The end product of PUFA peroxidation (8-isoprostane), the lipid mediator involved in the resolution of inflammatory exudates (resolvin D1), and the total amount of n-3 PUFAs were analyzed in the brains of mice. In Tw mice, supplementation with n-3 PUFAs delayed the manifestation of disease symptoms (p < 0.0001), and in the bran, decreased 8-isoprostane amounts (p < 0.0001), increased resolvin D1 levels (p < 0.005) and increased quantity of total n-3 PUFAs (p < 0.05). Furthermore, total brain n-3 PUFA levels were associated with disease severity (r = -0.562, p = 0.0001), resolvin D1 (r = 0.712, p < 0.0001), and 8-isoprostane brain levels (r = -0.690, p < 0.0001). For the first time in a natural model of KD, brain levels of n-3 PUFAs are shown to determine disease severity and to be involved in the peroxidation of brain PUFAs as well as in the production of pro-resolving lipid mediators. It is also shown that dietary supplementation with n-3 PUFAs leads to a slowing of the phenotypic presentation of the disease and restoration of lipid mediator production.

Assessment of Wavefront Aberrations in Children with Myopia Against the Background of Ocular Surface Disorders in Combination with Computer Vision Syndrome Digital and Eye Strain

Purpose: to assess the state of the wavefront in children with myopia, who have various manifestations of digital eye strain and symptoms of ocular surface disorders, and to evaluate the diagnostic significance of wavefront criteria for assessing the state of the ocular surface.Patients and methods. The study involved 76 children (152 eyes) with myopia aged 8 to 18 years who used gadgets and computers for more than 2 hours a day. All patients used glasses as a method of optical correction and were constantly worn. The patients were divided into 2 groups: 1st with symptoms of ocular surface disorder, 2nd — comparison group. Subjective signs were studied using the online questionnaire “State of the ocular surface”. Using the “Keratograph 5M Oculus” the following parameters were assessed: non­invasive tear film breakup time (NTBR), including the first tear film breakup time, average tear film breakup time, breakup time gradient and maximum tear film breakup zone, the same device was used to perform infrared meibography and study of the lipid layer of the tear film. All patients underwent wavefront aberrometry in a darkened room without cycloplegia.Results. It was found that in the group of patients with the presence of subjective phenomena of disturbance of the state of the ocular surface, identified using the online questionnaire “State of the ocular surface”, rotor aberrations were statistically significantly higher than in the comparison group. At the same time, the indicators of higher­order corneal aberrations have comparable values. Correlation analysis between indicators of the state of the ocular surface and parameters of the wavefront in the group of children with disturbances of the state of the ocular surface showed that a higher level of corneal aberrations corresponds to a higher number of points on the questionnaire of disturbances of the ocular surface and the state of visual comfort, in turn, when comparing data on non­invasive tear film breakup time, a negative correlation was established, which means that with a higher number of points on the questionnaire, and therefore, with a more significant degree of impairment of the ocular surface, the tear film breakup time was shorter.Conclusion. The structure of the wavefront in children with myopia against the background of a disorder of the ocular surface in combination with CVS and digital eye strain is significantly different from the structure of the wavefront in the comparison group.

Lack of inflammation or immune response in cyst tissue of patients with symptomatic non-hydrocephalic pineal cysts

Pineal cysts are frequently encountered as incidental findings in magnetic resonance imaging, usually devoid of symptoms, yet some patients exhibit symptomatic manifestations possibly associated with the cyst, even in the absence of hydrocephalus. The etiology of these symptoms remains contentious. This study aims to investigate the presence of lymphatic endothelial cell (LEC) markers and indications of inflammation or immune response within the pineal cysts of patients experiencing symptomatic non-hydrocephalic presentations. Eight patients who underwent surgical excision of their cysts were included in the study. Immunohistochemistry was utilized to assess the expression of LYVE-1, PDPN, and VEGFR3 as LEC markers, alongside IL-6 and CD3 for indications of inflammation or immune activity. Our analysis revealed an absence of inflammatory markers or immune response. However, a distinct expression of VEGFR3 was observed, likely localized to neurons within the pineal cyst tissue. We propose that these VEGFR3+ neurons within the pineal cyst may contribute to the headache symptoms reported by these patients. Further investigations are warranted to substantiate this hypothesis.

Association of H-FABP with cardiovascular events: A systematic review.

The research aimed to evaluate the association between heart-type fatty acid binding protein (H-FABP) and cardiovascular events. We systematically reviewed research that has been conducted to assess this relationship, aiming to determine how useful H-FABP could be as a biomarker for cardiovascular diseases, especially in the initial phases of acute myocardial infarction (AMI) and acute coronary syndrome (ACS). Our goal was to validate its diagnostic accuracy and clinical relevance. We systematically searched through PubMed, Web of Science, and Google Scholar databases to find pertinent publications related to cardiovascular diseases and H-FABP, using various permutations, abbreviations, and language variations of MeSH keywords. The final analysis included 12 studies in total. The final study comprised twelve studies, and it was concluded that H-FABP demonstrated high sensitivity (64.3-91.5) and specificity (73-100) for diagnosing Acute Myocardial Infarction (AMI) and Acute Coronary Syndrome (ACS), especially within the first hours of symptom onset. H-FABP demonstrates potential in enhancing the overall diagnostic accuracy during the initial hours following the manifestation of symptoms. However, the existing data do not provide sufficient evidence to recommend the regular utilization of H-FABP as a preliminary risk assessment approach in individuals who present with suspected cardiac events. Additional investigations, with well-defined prospective cohorts, are needed to validate the results observed.

Diagnostic dilemma in Cushing's syndrome: discrepancy between patient-reported and physician-assessed manifestations.

Early diagnosis and immediate treatment of Cushing's syndrome (CS) are critical for a better prognosis but remain a challenge. However, few comprehensive reports have focused on this issue or investigated whether patient-reported manifestations are consistent with physician-assessed symptoms of CS. This study aimed to clarify the differences in patient-reported and physician-assessed manifestations of signs and symptoms of CS that prevent early diagnosis. This single-center retrospective study included 52 patients with CS (16 with Cushing's disease and 36 with adrenal CS). Upon clinical diagnosis, medical records were used to independently review the patient-reported and physician-assessed manifestations of typical (such as purple striae and proximal myopathy) and nonspecific features (such as hirsutism and hypertension). The correlations and differences between the patient-reported and physician-assessed manifestations were then analyzed. We observed a positive correlation between the total number of manifestations of nonspecific features reported by patients and those assessed by physicians, but not for typical features. Moreover, manifestations reported by the patients were less frequent than those assessed by physicians for typical features, leading to discrepancies between the two groups. In contrast, there were no differences in most nonspecific features between the patient-reported and physician-assessed manifestations. Notably, the concordance between patient-reported and physician-assessed manifestations of typical features was not associated with urinary free cortisol levels. Regardless of disease severity, patients often do not complain of the typical features of CS that are crucial for formulating a diagnosis.

Psychological state, self-assessment y emotional stability of a severely wounded combatant

The article presents a comprehensive analysis of the peculiarities of the psychological state, self-esteem and emotional stability of severely wounded combatants who returned from combat. The research is based on the study of the psychological well-being of this category of victims, their adaptation and rehabilitation after severe physical injuries. The main focus is on identifying the manifestations of post-traumatic stress disorder (PTSD), depressive and anxiety symptoms in severely wounded combatants. It was found that severe combat trauma significantly increases the risk of developing mental disorders in victims, significantly complicating their recovery and return to a full-fledged peaceful life.The main factors that affect the emotional stability and general psychological state of severely wounded combatants are analyzed. These factors include physical pain and limitations, loss of functional capabilities, psychological trauma, social isolation, feelings of loss and helplessness, as well as problems with employment and financial stability. The role and importance of family care in supporting the psychological well-being of severely wounded combatants is considered. It is noted that effective rehabilitation requires close cooperation between medical professionals, psychologists, social workers and families of the victims. An important aspect is raising public awareness of the problems faced by severely wounded combatants and developing social support and adaptation programs for this category of people. Based on the results obtained, the article outlines the main areas of psychological assistance to severely wounded combatants. The author emphasizes the need for a comprehensive psychological rehabilitation program aimed at processing traumatic experiences and restoring self-esteem.
