100 Years of Benham's Top in Colour Science
1995
For 100 years Benham's top has been a popular device demonstrating pattern-induced flicker colours (PIFCs). Results of early and recent investigations on PIFCs are reported and show that the phenomenon originates in phase-sensitive lateral interactions of modulated neural activity in the retina followed by additional spatial interactions in the visual cortex behind the locus of binocular fusion. Colour matches with normal colour stimuli indicate that S/(M + L) opponent neurons are involved. Dichromats do not find matching stimuli for all PIFCs. PIFCs may become useful in medical diagnosis. The phenomenon is interpreted as a side effect of a neural mechanism providing colour constancy under…
Multifokale Intraokularlinsen
2001
Modern cataract surgery has developed tremendously during the past 10-15 years. Improved surgical techniques, as well as improved implant materials and designs, have enlarged patient profiles and indications for cataract surgery. This also created much higher expectations from the patients' site. The loss of accommodation is loss of quality of life for presbyopic and especially young pseudophakic patients. Therefore cataract surgery with multifocal IOL implantation is not only of academic interest, but reflects demands and expectations of our patients. Multifocal IOLs have been implanted since 1986, starting with 2-3 zone refractive and diffractive designs. Due to surgical techniques of tha…
Symptoms of psychological ill-being and school dropout intentions among upper secondary education students : a person-centered approach
2020
A person-centered approach was used to identify the profiles of symptoms of psychological ill-being among Finnish upper secondary education students (N = 2889); to examine whether gender and educational track (i.e., academic or vocational) are associated with these profiles; and to investigate the role of profiles in school dropout intentions. Using latent profile analysis, one asymptomatic profile (normative, 79.2%) and three symptomatic profiles (internalizing symptoms, 9.1%; externalizing symptoms, 9.1%; and comorbid symptoms, 2.6%) were identified. Boys in the vocational track were overrepresented in the externalizing-symptoms profile, whereas girls in both tracks were overrepresented i…
The role of lactate besides the lactic acidosis
2013
Lactic acidosis (LA) is the most common form of metabolic acidosis defined by values of lactate greater than 5 mmol / l and by a pH <7.34. The pathogenesis of LA involves hypoxic (type A) and non hypoxic (type B) causes which are often coexisting. Lactic acidosis is usual in hospitalized population especially in subjects in intensive care units, in which lactate levels on admission could be predictors of mortality even in the absence of organ dysfunction or shock. The outcome is mainly dependent on the cardiovascular effects of acidosis. In subjects with cardiogenic shock, the increased lactate/pyruvate ratio, detectable at onset, is correladed with mortality. An early assessment of blood a…
3., 5. un 6. deklinācijas lietvārdu lietojums latviešu valodā
2016
Bakalaura darba tēma ir „3.,5. un 6. deklinācijas lietvārdu lietojums latviešu valodā”. Daudzi šo deklināciju lietvārdi pārvietojas uz citām, ar tām notiek dažādas pārmaiņas. Darba mērķis ir izpētīt, kā mūsdienu latviešu valodā tiek lietoti 3., 5. un 6. deklinācijas lietvārdi, izmantojot dažādas interneta mājaslapas, galvenokārt ziņu portālus. Darbs sastāv no četrām nodaļām, no kurām pirmajā ir dots vispārīgs deklināciju raksturojums, kā arī ieskats to vēsturē un attīstībā. Pārējās nodaļās attiecīgi tiek raksturots 3., 5. un 6. deklinācijas sugasvārdu un īpašvārdu lietojums latviešu valodā. Izmantojot atlasītos piemērus un apgūto teorētisko literatūru, darba noslēgumā tiek secināts, ka latv…
Noninvasive Ventilation in Critically Ill Patients
2015
Since its first application in the late 1980s, noninvasive ventilation (NIV) has been the first-line intervention for certain forms of acute respiratory failure. NIV may be delivered through the patient's mouth, nose, or both using noninvasive intermittent positive pressure ventilation or continuous positive airway pressure. When applied appropriately, NIV may reduce morbidity and mortality and may avert iatrogenic complications and infections associated with invasive mechanical ventilation. This article provides physicians and respiratory therapists with a comprehensive, practical guideline for using NIV in critical care. © 2015 Elsevier Inc.
Parathyroid hormone serum concentration kinetic profile in critically ill patients undergoing continuous renal replacement therapies: a prospective o…
2021
Introduction: Elevated serum parathormone (PTH) levels have been observed in acute kidney injury and are related to calcium-phosphate metabolism disturbance, decreased renal production of 1,25 dihydroxyvitamin D3, impaired renal PTH excretion, and other renal-independent factors. There are no data regarding PTH concentration kinetics in critically ill patients undergoing continuous renal replacement therapies (CRRT) in an intensive care setting. The primary objective of this study was to investigate trends in PTH serum levels in critically ill patients with multiorgan failure undergoing CRRT, by performing periodic PTH measurements in the acute phase of critical illness. Material and method…

Medication errors and risk areas in a critical care unit
2020
The aim of this study was to identify the main medication errors, their causality and the highest risk areas in critical care.A descriptive, longitudinal and retrospective study.We performed a systematic analysis of the prescription, transcription and administration records of 2,634 dose units of medications that were administered to a total of 87 critically ill patients during 2018.Final results have shown important medication errors and a high number of significant drug interactions; prescription phase had the highest mistake rate (71%) and cause of errors (68%); transcription stage had a more variable error typology. A significant correlation was observed between the presence of causes a…
