Abstract: Introduction: Aging of skeletal muscles results in a cascade of events negatively affecting muscle mass, strength, and function, leading to reduced mobility, increased risk of falls, disability, and loss of independence. To date, different methods are used to assess muscle mechanical function, tensiomyography (TMG) being one of them. The aim of this review was twofold: to summarize the evidence-based usefulness of tensiomyography in older adults and to establish reference values for the main tensiomyography parameters in older adults. Methods: The PubMed, Web of Science, SPORTDiscus, and tensiomyography databases were searched from inception until 25 December 2022. Studies investigating older adults (aged 60+ years) that reported tensiomyographyderived parameters such as contraction time (Tc) and/or maximal displacement (Dm) were included. Methodological quality was assessed using the Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies. Results: In total, eight studies satisfied the inclusion criteria. Tensiomyography has been used on different groups of older adults, including asymptomatic, master athletes, patients with peripheral arterial disease, and patients with end-stage knee osteoarthritis with a mean age of 71.5 ± 5.38 (55.7% male subjects). The most evaluated were leg muscles such as vastus lateralis (VL), gastrocnemius medialis (GM), and biceps femoris (BF). The present review demonstrates that tensiomyography is used to assess neuromuscular function in asymptomatic and diseased older adults. When compared to asymptomatic individuals, power master athletes, knee osteoarthritis patients, and patients diagnosed with peripheral arterial disease have the shortest Tc in BF, VL, and GM muscles, respectively. On the other hand, endurance master athletes showed the longest Tc in all three evaluated muscles. Less mobile, nursing-home residents showed higher Dm in VL and BF, while lower Dm in GM than the asymptomatic group. The knee osteoarthritis group showed the largest Dm in BF and VL while having the smallest Dm in GM. Conclusion: Tensiomyography can serve as a valuable tool for assessing neuromuscular function in older adults. The method is sensitive to muscle composition, architecture, and (pre) atrophic changes of the skeletal muscles and might be responsive to muscle quality changes in aging and diseased populations.

Abstract: Obsevanje je del standardnega zdravljenja bolnic z rakom dojk. Odgovor na zdravljenje z obsevanjem je pri vsakem posamezniku drugačen in je odvisen tudi od genetskih dejavnikov. Eden od novejših genetskih označevalcev odgovora na obsevanje je dolžina telomerov. Telomeri ščitijo kromosome pred krajšanjem in vzdržujejo genomsko stabilnost. Rezultati naše raziskave kažejo, da se dinamika spreminjanja dolžine telomerov takoj po zdravljenju z obsevanjem in v šestih mesecih po obsevanju pri bolnicah z neinvazivnim rakom dojk spreminja in bi lahko služila kot biološki označevalec odgovora na obsevanje. Molekularni mehanizmi, povezani s tem procesom, ostajajo zaenkrat večinoma neraziskani.

Abstract: Huge quantities of fly ash and bottom ash are generated from thermal power plants and it presents great concern for country, mainly due to the environmental effects. In this study, fly ashes and bottom ash were characterized from technical and radiological aspects. Health effect due to the activity of radionuclides 226Ra, 232Th and 40K was estimated via radium equivalent activity (Raeq), external hazards index (Hex), the external absorbed dose rate (D) and annual effective dose rate (EDR). The specific surface area (40.25 m2 g−1), particle density (1.88 g cm−3) and LOI (23.49%) were typical for bottom ash. Siliceous fly ash contained 32% reactive silica. The annual effective dose rate for all ashes is ≤ 0.2 mSv y−1. Both, fly ash and bottom ash present potential secondary raw materials to be used for building purposes as result of their technological and radiological assessment.

Abstract: Na Onkološkem inštitutu Ljubljana smo leta 2018 v okviru Registra raka Republike Slovenije vzpostavili prvi nacionalni onkološki klinični register – klinični register kožnega melanoma. Poleg kazalnikov bremena raka (incidence, prevalence in preživetja), ki jih že 70 let spremljamo v okviru nacionalnega Registra raka, lahko sedaj na populacijski ravni merimo tudi kazalnike kakovosti obravnave bolnikov z melanomov. Kožni melanom sodi med rake, pri katerih incidenca v zadnjih desetletjih najbolj strmo narašča. Število novo zbolelih že presega mejo 600 oseb letno s čimer zavzema kožni melanom 6. mesto med vsemi novo odkritimi raki. Tako po incidenci, kot po umrljivosti je Slovenija zelo visoko na lestvici evropskih držav; po preživetju pa se uvrščamo nad evropsko povprečje. Kazalniki kakovosti obravnave in skladnosti obravnav s smernicami so na voljo za zbolele od leta 2017 naprej. Stroka si je že postavila ciljne vrednosti za vsakega od definiranih kazalnikov - kar nekaj postavljenih ciljev ostaja še pred nami
