    Wstęp. Współcześnie odnotowuje się wyraźny wzrost częstości występowania zaburzeń czynnościowych układu stomatognatycznego. Ma to zapewne związek ze wrastająca potrzebą dbałości o swoje zdrowie, ale także może wynikać z rzeczywistego wzrostu częstości występowania tej patologii. Duża aktualność problematyki skłoniła autorów do podjęcia badań własnych. Cel pracy. Celem badań była ocena częstości występowanie objawów bruksizmu wśród studentów krakowskich uczelni wyż-szych. Materiał i metody. Grupę badaną stanowiło 277 osób (172 kobie-ty i 105 mężczyzn) w wieku 19 - 29 lat, studentów krakowskich uczelni. Wykorzystano autorską ankietę oraz przeprowadzono krótkie badanie fizykalne. Wyniki i wnioski. Najczęściej odczuwaną dolegliwością wśród badanych był ból głowy. Zgłaszało go 80% respondentów, następnie zaburzony tor ruchu odwodzenia żuchwy, który rejestrowano u 78% badanych, trzaski w stawie skroniowo- żuchwowym, które podawało 50% badanych: obecność starć zębów i brak symetrii napięcia mięśni żwaczy , które stwierdzano z jednakową częstością u 38% badanych. Szumy uszne dotyczyły 22,74% badanych. Zaburzony tor odwodzenia żuchwy występował u 77,98% chorych z dysfuncją narządu żucia . Wnioski. Jednym z wiodących , choć niecharakterystycznych objawów dysfuncji narządu żucia jest ból. Chorym z zaburzeniami układu stomatognatycznego towarzyszyć mogą różnorodne objawy otologiczne występujące w dużym przedziale częstości.Introduction. Nowadays, there is a clear increase in the incidence of functional disorders of the stomatognathic system. This is probably related to the growing need to care for your health, but it also may result from a real increase in the incidence of this pathology. High relevance of the issues, prompted the authors to undertake their own research. Aim of the study. The aim of the study was to assess the frequency of the occurrence of bruxism symptoms among students of Krakow’s universities. Material and methods. The study group consisted of 277 people (172 women and 105 men) aged 19 – 29 who were students of Krakow’s universities. An original questionnaire was used and a short physical examination was carried out. Results and conclusions. The most frequently felt ailment among the subjects was headache. It was reported by 80% of respondents, followed by a disturbed mandibular movement pathway, which was recorded in 78% of respondents, cracks in the temporo-mandibular joint, which were given by 50% of subjects: presence of tooth clashes and lack of symmetry of masseter muscles, which were found at the same frequency in 38 % of respondents. Tinnitus related to 22.74% of the subjects. A disturbed mandibu-lar disorder pathway occurred in 77.98% of patients with masticatory system dysfunction

    Abstract Most rocky objects in the solar system, including the primitive chondrites and the terrestrial planets themselves, formed at oxygen fugacities ( f O2 ) near that of the Iron-Wü stite (IW) f O2 buffer. Conversely, the most ancient rocky objects of the solar system, the calcium aluminum-rich inclusions (CAIs), formed at f O2 values 5 orders of magnitude lower than the IW buffer in an environment more closely resembling a solar gas. High-resolution Mg isotope data and estimates for f O2 for rims on CAIs show that this shift from~solar to protoplanetary (chondritic) f O2 occurred in 100,000 to 300,000 yr for these objects. Magnesium isotopes show further that the rise in f O2 was accompanied by a rise in the partial pressure of Mg. These results establish that CAIs entered a region resembling where planet progenitors formed within 3 Â 10 5 yr of their formation in the solar nebula.

    The Maia detector array and x-ray fluorescence imaging system: Locating rare precious metal phases in complex samples

    X-ray fluorescence images acquired using the Maia large solid-angle detector array and integrated real-time processor on the X-ray Fluorescence Microscopy (XFM) beamline at the Australian Synchrotron capture fine detail in complex natural samples with images beyond 100M pixels. Quantitative methods permit real-time display of deconvoluted element images and for the acquisition of large area XFM images and 3D datasets for fluorescence tomography and chemical state (XANES) imaging. This paper outlines the Maia system and analytical methods and describes the use of the large detector array, with a wide range of X-ray take-off angles, to provide sensitivity to the depth of features, which is used to provide an imaging depth contrast and to determine the depth of rare precious metal particles in complex geological samples. © 2013 SPIE

    Impact of renal impairment on atrial fibrillation: ESC-EHRA EORP-AF Long-Term General Registry

    Background: Atrial fibrillation (AF) and renal impairment share a bidirectional relationship with important pathophysiological interactions. We evaluated the impact of renal impairment in a contemporary cohort of patients with AF. Methods: We utilised the ESC-EHRA EORP-AF Long-Term General Registry. Outcomes were analysed according to renal function by CKD-EPI equation. The primary endpoint was a composite of thromboembolism, major bleeding, acute coronary syndrome and all-cause death. Secondary endpoints were each of these separately including ischaemic stroke, haemorrhagic event, intracranial haemorrhage, cardiovascular death and hospital admission. Results: A total of 9306 patients were included. The distribution of patients with no, mild, moderate and severe renal impairment at baseline were 16.9%, 49.3%, 30% and 3.8%, respectively. AF patients with impaired renal function were older, more likely to be females, had worse cardiac imaging parameters and multiple comorbidities. Among patients with an indication for anticoagulation, prescription of these agents was reduced in those with severe renal impairment, p <.001. Over 24 months, impaired renal function was associated with significantly greater incidence of the primary composite outcome and all secondary outcomes. Multivariable Cox regression analysis demonstrated an inverse relationship between eGFR and the primary outcome (HR 1.07 [95% CI, 1.01–1.14] per 10 ml/min/1.73 m2 decrease), that was most notable in patients with eGFR <30 ml/min/1.73 m2 (HR 2.21 [95% CI, 1.23–3.99] compared to eGFR ≥90 ml/min/1.73 m2). Conclusion: A significant proportion of patients with AF suffer from concomitant renal impairment which impacts their overall management. Furthermore, renal impairment is an independent predictor of major adverse events including thromboembolism, major bleeding, acute coronary syndrome and all-cause death in patients with AF

    Clinical complexity and impact of the ABC (Atrial fibrillation Better Care) pathway in patients with atrial fibrillation: a report from the ESC-EHRA EURObservational Research Programme in AF General Long-Term Registry

    Background: Clinical complexity is increasingly prevalent among patients with atrial fibrillation (AF). The ‘Atrial fibrillation Better Care’ (ABC) pathway approach has been proposed to streamline a more holistic and integrated approach to AF care; however, there are limited data on its usefulness among clinically complex patients. We aim to determine the impact of ABC pathway in a contemporary cohort of clinically complex AF patients. Methods: From the ESC-EHRA EORP-AF General Long-Term Registry, we analysed clinically complex AF patients, defined as the presence of frailty, multimorbidity and/or polypharmacy. A K-medoids cluster analysis was performed to identify different groups of clinical complexity. The impact of an ABC-adherent approach on major outcomes was analysed through Cox-regression analyses and delay of event (DoE) analyses. Results: Among 9966 AF patients included, 8289 (83.1%) were clinically complex. Adherence to the ABC pathway in the clinically complex group reduced the risk of all-cause death (adjusted HR [aHR]: 0.72, 95%CI 0.58–0.91), major adverse cardiovascular events (MACEs; aHR: 0.68, 95%CI 0.52–0.87) and composite outcome (aHR: 0.70, 95%CI: 0.58–0.85). Adherence to the ABC pathway was associated with a significant reduction in the risk of death (aHR: 0.74, 95%CI 0.56–0.98) and composite outcome (aHR: 0.76, 95%CI 0.60–0.96) also in the high-complexity cluster; similar trends were observed for MACEs. In DoE analyses, an ABC-adherent approach resulted in significant gains in event-free survival for all the outcomes investigated in clinically complex patients. Based on absolute risk reduction at 1 year of follow-up, the number needed to treat for ABC pathway adherence was 24 for all-cause death, 31 for MACEs and 20 for the composite outcome. Conclusions: An ABC-adherent approach reduces the risk of major outcomes in clinically complex AF patients. Ensuring adherence to the ABC pathway is essential to improve clinical outcomes among clinically complex AF patients
