In the measurement of self-esteem, previous research assumes that all respondents are qualitatively similar. The assumption has not been adequately tested. The current study examines its validity using factor mixture modeling. Results reveal two qualitatively distinct classes the first provides more consistent responses to positive self-esteem items than the second. The correlations between positive and negative self-esteem suggest that self-esteem is essentially unidimensional in the first class but bidimensional in the second. Furthermore, those with high self-esteem are more likely to belong to the first class; those with low self-esteem are more likely to belong to the second class. The observed dimensionality of self-esteem depends on a person's level on the trait. Finally, we found that the two-class solution fits the data much better than a simple one-class, two-factor solution or a bifactor solution. Psychometric researchers should no longer ignore the possible existence of qualitatively distinct groups in an underlying population. We include Mplus syntax together with a detailed explanation for researchers to conduct similar investigations on constructs of interest.This report describes the Obstetric and Neonatal Simulation (ONE-Sim) workshop run in a remote learning format for medical and midwifery students in an interprofessional setting during the COVID-19 pandemic. It explores the observation of students as participants in the online learning of using Personal Protective Equipment and simulation-based learning of perinatal emergency management. This was followed by their mutual interaction and reflections. This paper aims to understand the role of synchronous remote learning through simulation and its impact on interprofessional interactions. We describe the experience of medical and midwifery students with the ONE-Sim workshop, facilitated by medical (obstetric and neonatal) and midwifery educators. Formal thematic analysis will be performed as part of the ongoing study; however, initial direct observation demonstrated that students reacted positively to the online ONE-Sim workshop and engaged well with facilitators and peers. Students mutually interacted amongst themselves, shared their previous experiences, knowledge of roles as medical and midwifery practitioners and how they see themselves in those roles in a perinatal emergency setting. The initial observations demonstrate that interprofessional education delivered in an e-learning format can be useful and meaningful, and may be utilized across a number of specialties.<br /><br /> This study aimed to determine possible associations between transcriptional and translational levels of clusterin (CLU) in the systemic and local joint environments with the severity of knee osteoarthritis (OA) and to investigate <br /><br /> mRNA expression in knee OA fibroblast-like synoviocytes (FLSs) stimulated with tumor necrosis factor-α.<br /><br /> Circulating and synovial fluid CLU levels in 259 knee OA patients were quantified using an enzyme-linked immunosorbent assay. Relative <br /><br /> mRNA expression in 50 knee OA synovial tissues and 4 knee OA FLSs was determined using real-time polymerase chain reaction.<br /><br /> Plasma CLU levels of knee OA patients were significantly higher than paired synovial fluid samples. Compared with early-stage knee OA patients, those with advanced-stage OA had considerably increased plasma and synovial fluid CLU levels. There were significant positive associations of plasma and synovial fluid CLU levels with radiographic severity of knee OA. Plasma CLU levels were directly correlated with its synovial fluid levels and high-sensitivity C-reactive protein levels in the patients. Receiver-operating characteristic curve analysis unveiled the potential utility of plasma CLU as a novel biomarker for knee OA severity (AUC = 0.80), with a sensitivity of 71.4% and a specificity of 73.3%. Marked upregulation of <br /><br /> mRNA expression was observed in both the inflamed synovial tissues and FLSs of knee OA.<br /><br /> Increased CLU mRNA and protein levels in the systemic and local joint environments of knee OA might reflect knee OA severity, especially systemic and synovial inflammation.<br /><br />Increased CLU mRNA and protein levels in the systemic and local joint environments of knee OA might reflect knee OA severity, especially systemic and synovial inflammation.<br /><br /> To demonstrate the immediate and medium-term results of the surgical treatment of patients with first metatarsophalangeal (MTP) joint osteoarthritis (OA) using the autologous matrix-induced chondrogenesis (AMIC) technique and to evaluate the effectiveness.<br /><br /> Preoperatively the range of motion (ROM) in the first MTP joint was determined, and the following questionnaires were used Visual Analogue Scale (VAS) of pain, American Orthopedic Foot &amp; Ankle Society (AOFAS) score, and Functional Foot Index (FFI). All of the patients experienced a significant restriction of the ROM in the first MTP joint. The VAS of pain median was 70, AOFAS 52, and FFI 5.8.<br /><br /> AMIC was performed in 19 patients with first MTP joint OA. All the patients experienced a significant restriction of ROM in the first MTP joint. The VAS of pain median was 70, AOFAS 52, and FFI 5.8. By the third month, VAS of pain decreased to 25, FFI to 2.2; AOFAS median increased to 77, ROM to 60°. Six months after the surgery VAS of pain decreased to 10, FFI to 1.1; AOFAS median increased to 90, ROM to 65°. After a year of observation, VAS of pain decreased to 5, FFI to 1,0; AOFAS median increased to 92.5, ROM to 71.5°.<br /><br /> The results showed that a first MTP joint AMIC procedure can be a fairly effective method of surgical treatment that can relieve pain and significantly improve the quality of life of patients with first MTP joint OA.<br /><br />The results showed that a first MTP joint AMIC procedure can be a fairly effective method of surgical treatment that can relieve pain and significantly improve the quality of life of patients with first MTP joint OA.<br /><br /> In the past enucleation was the treatment of choice for all the patients with uveal melanoma. Nowadays, we prefer glope-sparing treatment modalities, except for large tumors, tumors with extrascleral extension and painful blind eyes. Most of the patients perform radiotherapy or local resection techniques. In Slovak Republic, the only one possibility is astereotactic radiotherapy on alinear accelerator LINAC. Nevertheless, enucleation after radiotherapy is necessary for some patients. The causes are postradiation complications, mainly neovascular glaucoma, tumor recurrence, tumor progression or patient´sdecision.<br /><br /> The retrospective non-randomised study of 168 eyes of the patients with choroidal or ciliary body melanoma, who performed one-day session stereotactic radiosurgery at the linear accelerator LINAC during period 2007-2016. The data about postradiation complications were analysed based on the medical records of the patients and the data about enucleated eyes based on the histopathological findings.<br /><br />elanoma is difficult, and requires the cooperation of ophthalmologist, oncologist, radiation physicist and pathologist. Even if we make effort to preserve the eye, enucleation after radiotherapy is necessary in some patients.<br /><br /> Diagnostic and therapeutic management of the patient with malignant uveal melanoma (MMU) is subject to ongoing efforts to innovate. PET/CT (Positron Emission Tomography / Computed Tomography) examination is important in both diagnosis and metastases.<br /><br /> Evaluation of the importance of PET/CT examination in the group of patients diagnosed with MMU in the period 12.1.2016 to 6.12.2018. All patients with adiagnosis of secondary retinal detachment, suspected uveal melanoma, underwent standard examinations to detect possible metastases (liver ultrasound, chest X-ray). Patients for whom astereotactic radiosurgery solution was planned due to the stage of the disease this examination was to exclude metastasis in the liver or lungs. PET/CT examination is part of the protocol within the exclusion criteria for treatment with stereotactic radiosurgery in one day session surgery.<br /><br /> In the group of 84 patients, 47 women (56 %) and 37 men (44 %) were aged between 26 and 90 years. Their average age was 61.4 years. The mediall-body PET/CT examination.<br /><br />PET/CT examination is a technically demanding examination and is one of the possibilities of imaging intraocular melanoma in tumors with volume more than 0.5 cm3. It is important in determining the grading and staging of the disease before radiosurgical treatment and also in detecting possible metastases after MMU treatment in cases where ultrasound or MRI examinations do not give a definite result. However, our study confirmed the significance of this examination for randomly detected 2 duplex malignancies (2.4%) and 3 incidentalomas (3.6%) in patients whose ophthalmologist diagnosed uveal melanoma and sent patients for full-body PET/CT examination.The objective of this study was a retrospective assessment of two-year experience with micropulse cyclophotocoagulation (MP CPC) in the therapy of various types of glaucoma.<br /><br /> The cohort of patients consisted of 47 people, out of which 16 men and 31 women. An average age of males was 58.9 years (the range from 35 to 78 years), and an average age of females was 64.7 years (the range from 33 to 86 years). Both eyes were treated in three patients, and therefore the total number of assessed eyes was 50. Patients who underwent the therapy were in different stages of glaucoma disease, with various types of primary and secondary glaucoma. Most of the patients were those with primary open angle glaucoma (POAG) 26 patients, followed by patients with secondary pseudoexfoliative glaucoma (PEXG) 9 patients; diagnoses of the remaining patients 4 patients - secondary pigmentary glaucoma (PG), 3 patients - primary angle closure glaucoma (PACG), 2 patients normal tension glaucoma (NTG), 3 patients - Posner-Schlossman syndromey profile and predictability of results. In our study we achieved drop in the values of intraocular pressure by the minimum of 30% in 53.4% of treated eyes. Its use is not limited by the type of glaucoma disease. In the event of insufficient effect, it may be repeated.<br /><br />MP CPC is a non-incisional laser treatment with minimum complications. It is characterized by a high safety profile and predictability of results. In our study we achieved drop in the values of intraocular pressure by the minimum of 30% in 53.4% of treated eyes. Its use is not limited by the type of glaucoma disease. In the event of insufficient effect, it may be repeated.<br /><br /> Amblyopia is one of the most common childhood disease. The average prevalence of amblyopia in children is estimated at 2-5 %. It arises during the child development until the age of six, if not treated then, it persist throught adulthood. The aim of our work is to retrospectively analyze the results of treatment of anisometropic amblyopia using dichoptical training in virtual reality in adult amblyopic patients.<br /><br /> Our group consisted of 84 amblyopic patients with anisometropic amblyopia with an average age of 33.8 ± 9.4 years. Patients played avideo game twice aweek in the Oculus Rift 3D virtual reality. Together they completed 8 visual trainings, with one training lasting 60 minutes.
