Abstract	Body temperature measurement is one of the basic methods in clinical diagnosis. The problems of thermometry-interpretation of the accuracy and repeatability of various types of thermometers-are still being discussed, especially during the current pandemic in connection with the SARS-CoV-2 virus responsible for causing the COVID-19 disease. The aim of the study was to compare surface temperatures of the human body measured by various techniques, in particular a noncontact thermometer (infrared) and contact thermometers (mercury, mercury-free, electronic). The study included 102 randomly selected healthy women and men (age 18-79 years). The Bland-Altman method was used to estimate the 95% reproducibility coefficient, i.e., to assess the degree of conformity between different attempts. Temperatures measured with contact thermometers in the armpit are higher than temperatures measured without contact at the frontal area of the head. The methods used to measure with contact thermometers and a noncontact infrared thermometer statistically showed high measurement reliability. In order to correctly interpret the result of measuring human body temperature, it is necessary to indicate the place of measurement and the type of thermometer used.

Abstract	The limitations of the classic PACS (picture archiving and communication system), such as the backward-compatible DICOM network architecture and poor security and maintenance, are well-known. They are challenged by various existing solutions employing cloud-related patterns and services. However, a full-scale cloud-native PACS has not yet been demonstrated. The paper introduces a vendor-neutral cloud PACS architecture. It is divided into two main components: a cloud platform and an access device. The cloud platform is responsible for nearline (long-term) image archive, data flow, and backend management. It operates in multi-tenant mode. The access device is responsible for the local DICOM (Digital Imaging and Communications in Medicine) interface and serves as a gateway to cloud services. The cloud PACS was first implemented in an Amazon Web Services environment. It employs a number of general-purpose services designed or adapted for a cloud environment, including Kafka, OpenSearch, and Memcached. Custom services, such as a central PACS node, queue manager, or flow worker, also developed as cloud microservices, bring DICOM support, external integration, and a management layer. The PACS was verified using image traffic from, among others, computed tomography (CT), magnetic resonance (MR), and computed radiography (CR) modalities. During the test, the system was reliably storing and accessing image data. In following tests, scaling behavior differences between the monolithic Dcm4chee server and the proposed solution are shown. The growing number of parallel connections did not influence the monolithic server's overall throughput, whereas the performance of cloud PACS noticeably increased. In the final test, different retrieval patterns were evaluated to assess performance under different scenarios. The current production environment stores over 450 TB of image data and handles over 4000 DICOM nodes.

Abstract	Introduction: High social cost and high risk of disability make postmenopausal osteoporosis one of major public health problem in the 21 Material and methods: The survey included 450 postmenopausal women (age 65 ±11 years). A detailed questionnaire included demographic and anthropometric data, comorbidity, history of previous low-energy fractures, family medical history, and treatment for osteoporosis. The FRAX calculator was used to estimate the risk of MOF and HF. Results: Osteoporosis was previously diagnosed in 23.7% women. Of those 70.2% were receiving vitamin D, 27% calcium preparations, 33% bisphosphonates, and 22% were untreated. Only 42.2% women with previous fractures had been diagnosed with osteoporosis and 42.8% received any treatment. 12.5% women with FRAX-BMD ≥ 10% had no risk factors of osteoporosis and < 10% risk of MOF and HF in FRAX without BMD. Conclusions: Osteoporosis often remains undiagnosed and untreated in postmenopausal women. There is a great need to popularize FRAX without BMD calculator among physicians, especially GPs, as the risk calculation justify the implementation of antiosteoporotic therapy. Women with burden of risk factors of fractures and borderline FRAX without BMD values, should be referred to a densitometry examination, as having greater risk of fracture than shown by FRAX without BMD.

Abstract	Sclerostin is a glycoprotein involved in the regulation of bone metabolism, exclusively secreted by osteocytes. It affects the activity of bone morphogenetic proteins (BMPs) and is an inhibitor of the Wnt/β-catenin metabolic pathway in bone cells. Osteocytes reduce the release of sclerostin in response to mechanical stimuli acting on bone, and thus promote the activation of osteogenic pathway Wnt/β-catenin in osteoblasts. This signaling pathway plays a key role in osteogenesis and bone turnover. Loss of sclerostin gene function is related to 3 different craniotubular hyperostosis processes: sclerosteosis, craniodiaphyseal dysplasia, and van Buchem disease. Additionally, experimental and clinical studies suggest that sclerostin may promote vascular calcification. Antibodies directed against sclerostin stimulate bone formation and represent a new therapeutic option in the treatment of diseases with increased bone resorption, such as osteoporosis and inflammatory diseases where there is generalized bone loss, periarticular osteoporosis, and cartilage damage, such as rheumatoid arthritis (RA), ankylosing spondylitis (AS), and glucocorticoid-induced osteoporosis (GIO). Antibody use has the potential to offer new therapeutic approaches in the therapy of mineral and bone disorders resulting from chronic kidney disease (CKD-MBD) and vascular calcifications.

Abstract	Purpose: Data concerning the relation between increased levels of circulating sclerostin (a physiological inhibitor of bone formation) and bone turnover in patients with chronic renal failure (CRF) are limited. Therefore, the aim of this study was to evaluate associations between plasma sclerostin levels and calcium-phosphate disturbances, markers of bone turnover as well as inflammation in haemodialysis (HD) patients. Methods: In plasma samples obtained in 150 stable HD patients (92 men) aged 40-70 years, levels of sclerostin, fibroblast growth factor (cFGF23), osteocalcin, the N-terminal propeptide of type I procollagen, C-terminal telopeptide of the alpha chain of type I collagen (β-CTx), and inflammatory markers (IL-6 and TNF-α) in addition to routine parameters (calcium, phosphorus, parathyroid hormone-iPTH, 25-OH-D, alkaline phosphatase) were measured. Results: Plasma sclerostin concentrations were significantly higher in HD men than women (2.61 vs. 1.88 ng/mL, p < 0.01). Patients with sclerostin levels above median were characterized by lower iPTH and IL-6, but higher cFGF23 and TNF-α (significantly only in men) concentrations. Plasma sclerostin concentration positively correlated with serum 25-OH-D (τ = 0.204), phosphorus (τ = 0.1482), and TNF-α (τ = 0.183) and inversely with iPTH (τ = - 0.255), alkaline phosphatase (τ = - 0.203), IL-6 (τ =- 0.201), and β-CTx (τ = - 0.099) levels. In multivariate regression analysis, variability of sclerostin levels was explained by sex and 25-OH-D and phosphorus levels. Conclusions: Increased circulating sclerostin levels seem to reflect slower bone turnover in HD patients. Low levels of sclerostin are associated with vitamin D deficiency and good phosphates alignment.

Abstract	Background: Symptoms of depression are common in patients diagnosed with benign prostatic hyperplasia (BPH) and are usually a reaction to deterioration of health, severity of lower urinary tract symptoms, and erectile dysfunction. The aim of this observational study was to evaluate the prevalence of depressive symptoms in patients diagnosed with BPH and factors affecting their occurrence in a large Polish cohort. Patients and methods: Four thousand thirty-five men (4,035) diagnosed with BPH participated in the survey (age 65 ± 8 years). The occurrence of symptoms of depression was assessed using the Beck depression inventory, severity of lower urinary tract symptoms (LUTS) on the basis of the international prostate symptoms score, and erectile dysfunction using the international index of erectile function (IIEF-5). Results: Depressive symptoms were found in 22.4% of patients (mild in 20.8% and moderate/severe in 1.6%). Erectile dysfunction was found in 71.9% of patients. Monotherapy for BPH was prescribed to 50.9% of patients (mostly ARA-selective α1-selective alpha-adrenolytic-47.5%), while polytherapy (ARA with a 5-alpha reductase inhibitor-5αRI) to 47.9%. Logistic regression analysis showed a bidirectional relation between the occurrence of depressive symptoms and erectile dysfunction. The occurrence of both depressive symptoms and erectile dysfunction was related to severity of LUTS, nocturia, the use of 5αRI, comorbidity, and sedentary life style. Conclusions: Prevalence of depressive symptoms in patients diagnosed with BPH is associated with severity of LUTS, erectile dysfunction, nocturia, BPH pharmacotherapy (5αRIs), sedentary life style, and comorbidities including obesity.
