THE CORINI ACTIVE FAULT IN SOUTHWESTERN VIOTIA REGION, CENTRAL GREECE: SEGMENTATION, STRESS ANALYSIS AND EXTENSIONAL STRAIN PATTERNS

Στην εργασία παρουσιάζονται νέα γεωλογικά δεδομένα για ένα ενεργό ρήγμα της Νοτιοδυτικής Βοιωτίας. Η περιοχή αυτή χαρακτηρίζεται από χαμηλή παραμόρφωση συγκρινόμενη με τις νεοτεκτονικές τάφρους τόσο του Κορινθιακού (προς Δυσμάς) όσο και του Ευβοϊκού (προς ανατολάς). Το κανονικό ρήγμα της Κορύνης αποτελείται από δύο μεγάλα τμήματα και μερικά αρκετά μικρότερα με μέση παράταξη ΑΒΑ-ΔΝΔ (Β58°) και φορά κλίσεως προς ΝΑ. Το ρήγμα έχει συνολικό μήκος 12 km και έχει αναπτυχθεί στο ανθρακικό υπόβαθρο της Υποπελαγονικής. Η αρχιτεκτονική της ρηξιγενούς ζώνης χαρακτηρίζεται από την ύπαρξη ενός τεκτονικού λατυποπαγούς με μέσο πάχος 15 εκατοστών. Στην βάση του καθρέπτη της Κορύνης παρατηρείται λωρίδωση με μικρή έως καθόλου διάβρωση πάχους 20-30 εκατοστών, η οποία αντιπροσωπεύει την τελευταία σεισμική κίνηση του ρήγματος με άνοδο του σταθερού τεμάχους. Αναφορικά με την κινηματική το σημαντικότερο εύρημα έγκειται στο ότι ο ελάχιστος άξονας της κύριας τάσης έχει μέση διεύθυνση Β328°Α, η οποία περίπου ταυτίζεται με αυτή των ενεργών ρηγμάτων της νότιας ακτής της Κορινθιακής τάφρου (χερσόνησος Περαχώρας).The Corini normal fault is an active structure of Quaternary age in Southwestern Viotia. This is a region of low finite strain, located between the Quaternary rifts of the Gulf of Corinth and the Gulf of Evia. The fault is segmented into several segments with an average strike of N58°E and dip direction to the SE. The architecture of the fault zone is characterized by a 15 cm thick gouge rock, observed along the fault plane on the footwall side. At several localities along strike we observed a well-defined basal strip of un-eroded fault plane that represents the width (uplift) of the last co-seismic slip. The width of the strip ranges 20-30 cm. Slip inversion data show a mean orientation ofsigmaS (leastprincipal stress) as Ν328Έ which implies similar kinematics with the active faults of the south coast of the Gulf of Corinth

The extreme yet transient nature of glacial erosion

Ice can sculpt extraordinary landscapes, yet the efficacy of, and controls governing, glacial erosion on geological timescales remain poorly understood and contended, particularly across Polar continental shields. Here, we assimilate geophysical data with modelling of the Eurasian Ice Sheet — the third largest Quaternary ice mass that spanned 49°N to 82°N — to decipher its erosional footprint during the entire last ~100 ka glacial cycle. Our results demonstrate extreme spatial and temporal heterogeneity in subglacial erosion, with rates ranging from 0 to 5 mm a−1 and a net volume equating to ~130,000 km3 of bedrock excavated to depths of ~190 m. A hierarchy of environmental controls ostensibly underpins this complex signature: lithology, topography and climate, though it is basal thermodynamics that ultimately regulates erosion, which can be variously protective, pervasive, or, highly selective. Our analysis highlights the remarkable yet fickle nature of glacial erosion — critically modulated by transient ice-sheet dynamics — with its capacity to impart a profound but piecemeal geological legacy across mid- and high latitudes

Automated office blood pressure measurements in primary care are misleading in more than one third of treated hypertensives: The VALENTINE-Greece Home Blood Pressure Monitoring study

Abstract Background This study assessed the diagnostic reliability of automated office blood pressure (OBP) measurements in treated hypertensive patients in primary care by evaluating the prevalence of white coat hypertension (WCH) and masked uncontrolled hypertension (MUCH) phenomena. Methods Primary care physicians, nationwide in Greece, assessed consecutive hypertensive patients on stable treatment using OBP (1 visit, triplicate measurements) and home blood pressure (HBP) measurements (7 days, duplicate morning and evening measurements). All measurements were performed using validated automated devices with bluetooth capacity (Omron M7 Intelli-IT). Uncontrolled OBP was defined as ≥140/90 mmHg, and uncontrolled HBP was defined as ≥135/85 mmHg. Results A total of 790 patients recruited by 135 doctors were analyzed (age: 64.5 ± 14.4 years, diabetics: 21.4%, smokers: 20.6%, and average number of antihypertensive drugs: 1.6 ± 0.8). OBP (137.5 ± 9.4/84.3 ± 7.7 mmHg, systolic/diastolic) was higher than HBP (130.6 ± 11.2/79.9 ± 8 mmHg; difference 6.9 ± 11.6/4.4 ± 7.6 mmHg, p Conclusions In primary care, automated OBP measurements are misleading in approximately 40% of treated hypertensive patients. HBP monitoring is mandatory to avoid overtreatment of subjects with WCH phenomenon and prevent undertreatment and subsequent excess cardiovascular disease in MUCH

Prevalence, associated factors and outcomes of pressure injuries in adult intensive care unit patients: the DecubICUs study

Funder: European Society of Intensive Care Medicine; doi: http://dx.doi.org/10.13039/501100013347Funder: Flemish Society for Critical Care NursesAbstract: Purpose: Intensive care unit (ICU) patients are particularly susceptible to developing pressure injuries. Epidemiologic data is however unavailable. We aimed to provide an international picture of the extent of pressure injuries and factors associated with ICU-acquired pressure injuries in adult ICU patients. Methods: International 1-day point-prevalence study; follow-up for outcome assessment until hospital discharge (maximum 12 weeks). Factors associated with ICU-acquired pressure injury and hospital mortality were assessed by generalised linear mixed-effects regression analysis. Results: Data from 13,254 patients in 1117 ICUs (90 countries) revealed 6747 pressure injuries; 3997 (59.2%) were ICU-acquired. Overall prevalence was 26.6% (95% confidence interval [CI] 25.9–27.3). ICU-acquired prevalence was 16.2% (95% CI 15.6–16.8). Sacrum (37%) and heels (19.5%) were most affected. Factors independently associated with ICU-acquired pressure injuries were older age, male sex, being underweight, emergency surgery, higher Simplified Acute Physiology Score II, Braden score 3 days, comorbidities (chronic obstructive pulmonary disease, immunodeficiency), organ support (renal replacement, mechanical ventilation on ICU admission), and being in a low or lower-middle income-economy. Gradually increasing associations with mortality were identified for increasing severity of pressure injury: stage I (odds ratio [OR] 1.5; 95% CI 1.2–1.8), stage II (OR 1.6; 95% CI 1.4–1.9), and stage III or worse (OR 2.8; 95% CI 2.3–3.3). Conclusion: Pressure injuries are common in adult ICU patients. ICU-acquired pressure injuries are associated with mainly intrinsic factors and mortality. Optimal care standards, increased awareness, appropriate resource allocation, and further research into optimal prevention are pivotal to tackle this important patient safety threat

The Hellenic Voice Handicap Index of Different Laryngeal Mass Lesions: A Receiver-Operating Characteristic Analysis

Background: Voice disorders influence the quality of people's life. When the type of disorder is determined then the clinicians are capable of finding their patients’ needs and address their complaints concerning their vocal problems. One of the most used tools, for assessing the patients’ quality of life (in accordance with their vocal status), is the Voice Handicap Index. In this study, we determined the cut-off scores of Voice Handicap Index for population with laryngeal mass lesions such as vocal polyps and nodules. The calculated cut-off points further guide clinicians toward applying a needed interventional method/therapy even in the cases where the condition of a person could not be easily estimated. Methods: The study involved 130 participants (aged 19–74). Specifically, 90 nondysphonic people served as the control group, while 40 participants had already been diagnosed with voice disorders due to laryngeal mass lesions. Participants who were diagnosed with a laryngeal inflammation or had undergone a surgery were excluded from the study. The cut-off scores were determined through a receiver-operating characteristic (ROC) analysis. Results: The calculated cut-off points were 19.50 for the total score of VHI, 7.50 for the functional domain, and 8.50 for the physical and the emotional domain. Conclusions: The aforementioned cut-off points could be used in empowering the everyday clinical practice. Moreover, their knowledge could help the construction of an individualized therapy plan, as well as monitoring-biofeedback tool for the populations with vocal fold lesions. © 2019 The Voice Foundatio
