New constraints on the Middle Palaeozoic to enozoic burial and hermal history of the Holy ross Mts. (Central Poland) : results of numerical modelling

A 1-D burial-thermal modelling was performed using data from two borehole sections representative of the central part of the Holy Cross Mts. area. This area is located in the axial part of the Permian-Mesozoic Mid-Polish Trough that was inverted during the latest Cretaceous-Paleocene. The modelling involved different variants of restored stratigraphy of eroded Carboniferous to Cretaceous strata, whereas calibration was based on samples from cored Middle-Upper Devonian sediments. The modelling results are consistent with the assumption of a Variscan (Carboniferous-Early Permian) heat flow elevated up to 80 mWm-2, which is further confirmed by independent regional evidence. The zone of increased thermal maturity in the Devonian may be partly accounted for by a thicker Carboniferous section (by ca. 500 m) compared to previous estimates. Two variants of the post-Carboniferous geohistory were analysed. The variant of a thinner Permian-Mesozoic section, implying lower magnitude of the Late Cretaceous-Paleogene inversion, allows more realistic assumptions regarding heat flow distribution through time, including the possibility to incorporate an elevated Variscan heat flow. The alternative scenario, assuming deeper burial, generally lower heat flow and smaller Carboniferous thickness, is regarded as less probable. The accepted variant of the Permian-Mesozoic burial history implies that the total post-Carboniferous burial in the study area was on the order of 2000-2500 metres rather than 3000-3500 metres. The respective Upper Cretaceous thickness could have been 400 to 500 m instead of ca. 1000 m, whereas the Late Cretaceous Paleogene inversion more likely started in the Santonian than in the late Maastrichtian. Consequently, the preferred magnitude of total inversion was on the order of 2500 m

Utility of polygraphic studies for sleep apnea screening in the setting of tertiary care hypertension outpatient clinic

Background: Prevalence of obstructive sleep apnea (OSA) in patients with hypertension outnumbers the prevalence reported in the general population. Concurrently, majority of patients remain undiagnosed. Given the fact that untreated OSA contributes to ineffective hypotensive treatment, and higher rate of complications is ascribed to hypertension, early OSA diagnosis and its elimination constitutes one of the key clinical goals. Polysomnography comprises a golden standard in sleep apnea diagnosis, however it is a time-consuming and expensive procedure which requires hospitalization. Therefore, we assessed the utility of simplified polygraphic (PG) studies in the OSA screening of patients with hypertension requiring regular tertiary care. Material and methods: The study was conducted in the Outpatient Tertiary Care Clinic of the Medical University Hospital of Gdansk. We enrolled consecutive patients regardless of OSA symptoms presence (n = 243), as well as patients with OSA suspicion (n = 75). A total of 318 patients (39% females) were subjected to ambulatory, one night polygraphic study (ApneaLink™). The following signals were recorded: airflow (pressure cannula), respiratory movements, and pulse oximetry. Additionally, anthropometrics, Epworth Sleepiness Scale (ESS), selected clinical symptoms, and drug-regimen were recorded. Results: Three hundred and eight (97%) patients completed the study (10 dropouts due to study failure). Patients were 57.7 ± 11.5 years old, had BMI = 30.0 ± 5.0 kg/m2, and average ESS = 5.7 ± 4.6. 65.3% of all patients were characterized by AHI ≥ 5 (62.2% vs. 74.7% in Random vs. Symptomatic group, respectively; P = 0.49), whereas 27.6% of patients were diagnosed with AHI ≥ 15 (23.6% in Random group and 40.0% in Symptomatic group). In logistic regression analysis, nocturia (> 2) increased the odds of AHI ≥ 30 diagnosis approximately 3.5 times in a fully adjusted model. Conclusions: Our results justify routine polygraphic screening of hypertensive patients requiring tertiary care. Abridged medical history may substantially increase the odds for positive screening.Background: Prevalence of obstructive sleep apnea (OSA) in patients with hypertension outnumbers the prevalence reported in the general population.

Awareness of the role of cardiovascular risk factors and their prevention from the perspective of Tricity adolescents

Introduction. Arterial hypertension (HT) affects 10.4 million adult Poles, and the blood pressure (BP) control rate is only 26%. Beyond any doubt, high blood pressure results in cardiovascular (CV) target organ damage, which markedly influences national healthcare programs. Childhood introduced cardiovascular prophylaxis offers opportunities to decrease incident HT and delay or even eliminate its consequences. Therefore we have decided to study the level of knowledge on HT and CV disease (CVD) among random 1st and 2nd grade high school students in Tricity, Poland. Material and methods. Questionnaire-based study was conducted voluntarily in two selected high schools of the Tricity agglomeration, Poland, in 2000 and repeated in 2016. All participants were presented with a 38-item questionnaire on cardiovascular risk factors knowledge as well as students’ health habits. Results. Studied group consisted of 615 students (57.6% females) at the age of 16, mean BMI 20.89 ± 2.95 kg/m2 (78% BMI norm). The evaluation of the several habits in two time-points was as follows: additional salt intake was reported by 38.3% vs. 35.1% adolescents in 2000 and 2016, respectively; p = 0.43, dining in fast food restaurants at least once a week: 13.9% vs. 44.8%; 2000/2016; p < 0.01; hours per week spent on physical activity: 5.6 ± 4.4 vs. 5.5 } 4.5; p = 0.85; students who never drank alcohol: 19.7% vs. 31.1%; p < 0.01; cigarettes ever smoking: 39.6% vs. 21.2%; p < 0.01; regular smokers: 10.2% vs. 4.1%; p < 0.05. The awareness of CV-preventive measures such as body weight reduction was presented by 88.1% vs. 93.9% students in 2000 vs. 2016; p = 0.01; regular physical activity 92.6% vs. 97.1%; P = 0.01, limiting smoking and alcohol consumption 84.2% vs. 91.2%; p = 0.01; salt reduction: 62.6% vs. 82.3%; p < 0.001. Interestingly, in 2016 the majority of students identified myocardial infarction as a consequence of AH 92.4%, which was markedly less evident in case of stroke and kidney disease (46.2%, and 28%, respectively). Conclusion. Although the awareness of negative consequences of HT and other CV-risk factors has grown over the past 15 years, the implementation of this knowledge is insufficient among high-school adolescents.

Formation of diazohydroxides ArN 2 OH in aqueous acid solution: polarographic determination of the equilibrium constant K R for the reaction of 4-substituted arenediazonium ions with H 2 O †

In aqueous acid (pH <4) solutions, in the dark, and in the absence of reductants, arenediazonium ions, ArN 2 + decompose spontaneously through the rate-limiting formation of the extremely unstable aryl cation that reacts with any nucleophile present in its solvation shell (D N + A N mechanism). However, in weak acidic and alkaline solutions, + to determine, for the first time, the equilibrium constants K R of formation of 4-substituted X-ArN 2 OH (X¼H, Me, MeO, Br, and NO 2 ), which can decompose in several ways including Z-E isomerization or further reaction with OH À to give diazoate ArN 2 O À . The technique applied was differential pulse polarography, which is very selective and sensitive. The determined pK R values are 5-6, and they are somewhat higher than those obtained for the reaction of ArN 2 + with alcohols ROH (pK DE = 3-5) under similar acidic conditions. The K R values are not very sensitive to changes in the nature of the substituent in the aromatic ring and a linear Hammett plot with a slope of ρ = 0.58 was obtained

Left ventricular function after takotsubo is not fully recovered in long-term follow-up: A speckle tracking echocardiography study

Background: Complete improvement of left ventricle (LV) systolic function is an essential feature of takotsubo cardiomyopathy (TTC). It is suggested that 2-dimensional speckle tracking echocardiography (2D STE) can evaluate LV dysfunction more accurately than conventional echocardiography. Thus, the purpose of this research was to assertain whether LV function recovery is complete after the acute phase of TTC using 2D STE commencing 6 to 9 months after discharge. Methods: Thirty patients (29 females, 67 ± 11 years) with an apical ballooning TTC pattern 225.5 ± 27.4 days after their index event were enrolled. The control group consisted of 20 (19 females, 64  ± 9 years) age- and sex-matched volunteers without structural heart disease. Classic echocardiographic parameters, longitudinal strain and LV twist parameters were assessed and compared between the groups. Results: There were no differences in traditional LV systolic, diastolic parameters and in global peak longitudinal strain. In comparison to controls, patients with TTC had lower mean apical rotation (14.4° ± 6.5° vs. 18.3° ± 6.7°; p = 0.048), slower mean peak early diastolic apical rotation rate (–85.1−°/s ± 40.9−°/s vs –119.4−°/s ± 41.9−°/s; p = 0.006) and higher pre-stretch index in the apex (2.16, IQR 0.33–5.50 vs. 0.00, IQR 0.00–2.95, p = 0.008). Conclusions: The improvement of LV function in patients with TTC as assessed by 2D STE may not always be complete. Some residual abnormalities in LV apex function were observed in long-term recovery following TTC episodes.

Neuronal haemoglobin induces loss of dopaminergic neurons in mouse Substantia nigra, cognitive deficits and cleavage of endogenous α-synuclein

Parkinson's disease (PD) presents the selective loss of A9 dopaminergic (DA) neurons of Substantia Nigra pars compacta (SNpc) and the presence of intracellular aggregates called Lewy bodies. alpha-synuclein (alpha-syn) species truncated at the carboxy-terminal (C-terminal) accumulate in pathological inclusions and promote alpha-syn aggregation and toxicity. Haemoglobin (Hb) is the major oxygen carrier protein in erythrocytes. In addition, Hb is expressed in A9 DA neurons where it influences mitochondrial activity. Hb overexpression increases cells' vulnerability in a neurochemical model of PD in vitro and forms cytoplasmic and nucleolar aggregates upon short-term overexpression in mouse SNpc. In this study, alpha and beta-globin chains were co-expressed in DA cells of SNpc in vivo upon stereotaxic injections of an Adeno-Associated Virus isotype 9 (AAV9) and in DA iMN9D cells in vitro. Long-term Hb over-expression in SNpc induced the loss of about 50% of DA neurons, mild motor impairments, and deficits in recognition and spatial working memory. Hb triggered the formation of endogenous alpha-syn C-terminal truncated species. Similar alpha-syn fragments were found in vitro in DA iMN9D cells over-expressing alpha and beta- globins when treated with pre-formed alpha-syn fibrils. Our study positions Hb as a relevant player in PD pathogenesis for its ability to trigger DA cells' loss in vivo and the formation of C-terminal alpha-syn fragments

Zastosowanie przesiewowych badań poligraficznych w diagnostyce bezdechu sennego u pacjentów z nadciśnieniem tętniczym wymagających specjalistycznej opieki ambulatoryjnej

Wprowadzenie: Pacjenci z nadciśnieniem tętniczym (NT) charakteryzują się znacznie częstszym współwystępowaniem obturacyjnego bezdechu sennego (OBS) w porównaniu do populacji ogólnej. Nieleczony bezdech zmniejsza efektywność terapii hipotensyjnej, a także w złożonym mechanizmie związany jest ze wzrostem występowania powikłań sercowo-naczyniowych charakterystycznych dla nadciśnienia tętniczego. W tym świetle, wczesna diagnostyka OBS i jego skuteczne leczenie stanowi jeden z podstawowych celów w postępowaniu z chorym z nadciśnieniem tętniczym, co jest szczególnie istotne z uwagi na niską rozpoznawalność OBS w tej grupie chorych. Złotym standardem w diagnostyce zaburzeń snu stanowi polisomnografia, która jednak jest procedurą czasochłonną, wymagająca istotnych nakładów środków finansowych i przeprowadzenia hospitalizacji. Z tego względu celem naszej pracy była ocena zastosowania uproszczonych badań poligraficznych (PG) jako metody badań przesiewowych u pacjentów z nadciśnieniem tętniczym wymagających specjalistycznej opieki ambulatoryjnej. Materiały i metody: Badanie zostało przeprowadzone w Regionalnym Centrum Nadciśnienia Tętniczego UCK, GUMed w Gdańsku. Do badania zostało włączonych 234 pacjentów bez względu na występowanie lub brak objawów OBS, a także 75 pacjentów z klinicznym podejrzeniem choroby. Łącznie 318 (39% kobiet) chorych zostało poddanych ambulatoryjnej ocenie poligraficznej przez okres jednej nocy. Rejestracja poligraficzna obejmowała następujące sygnały: przepływ powietrza (kaniula ciśnieniowa), ruchy oddechowe i pulsoksymetria. Dodatkowo zebrano dane antropometryczne, informacje dotyczące wybranych objawów klinicznych oraz przyjmowanych leków, a także oceniono stopień senności przy pomocy kwestionariusza Epworth Sleepiness Scale (ESS). Wyniki: Trzystu ośmiu (97%) pacjentów ukończyło badanie (10 pacjentów wykluczono ze względu na niedostateczną jakość rejestracji). Pacjenci mieli średnio 57,7 ± 11,5 roku, BMI = 30,0 ± 5,0 kg/m2 oraz średni wynik w skali ESS = 5,7 ± 4,6. W badanej grupie 65,3% charakteryzowało się AHI ≥ 5 (62,2% vs. 74,7%, odpowiednio w grupie losowej i objawowej). W analizie wieloczynnikowej wykazano, że nykturia powyżej 2 ×, 3,5-krotnie zwiększała ryzyko rozpoznania ciężkiej postaci OBS (AHI > 30). Wnioski: Nasze badanie potwierdza wysoką trafność screeningu poligraficznego u pacjentów z nadciśnieniem tętniczym w rozpoznawaniu OBS. Właściwa interpretacja podstawowych danych klinicznych pacjenta, istotnie zwiększa szansę na dodatni screening
