Deviance detection in sound frequency in simple and complex sounds in urethane-anesthetized rats
2019
Mismatch negativity (MMN), which is an electrophysiological response demonstrated in humans and animals, reflects memory-based deviance detection in a series of sounds. However, only a few studies on rodents have used control conditions that were sufficient in eliminating confounding factors that could also explain differential responses to deviant sounds. Furthermore, it is unclear if change detection occurs similarly for sinusoidal and complex sounds. In this study, we investigated frequency change detection in urethane-anesthetized rats by recording local-field potentials from the dura above the auditory cortex. We studied change detection in sinusoidal and complex sounds in a series of …
Alcohol Use Disorder and Depression in Patients with Alcohol-Related Seizures
2018
Abstract Both alcohol use disorder and depression are important aspects of health in the general population and among patients with epilepsy. Depression is the most prevalent psychiatric comorbidity in epilepsy, thereby increasing morbidity as well as mortality rate. From our experience, we can see that one third of epilepsy inpatients experience seizures that are alcohol-related. There have been no studies conducted in Latvia about alcohol use disorder and depression in patients with alcohol-related seizures (ARS) and epilepsy. We recruited 108 patients with ARS, 44 of whom had comorbid epilepsy. 75% of patients in our study had depression according to the Hamilton depression scale. Higher…
Population-based cancer registries in Spain and their role in cancer control
2010
Abstract Population-based cancer registries (PBCRs) are a key element for cancer control. They measure cancer incidence and trends, provide indicators for planning and evaluating cancer control activities, and undertake research. The first two PBCRs in Spain were established in Zaragoza in 1960 and Navarre in 1970, but it was from 1980 to 1995 when most of the existing registries went into operation. Today, 26.5% of the Spanish population is served by a cancer registry. All registries’ quality-control indicators meet the inclusion criteria for comparability and quality of data required by the International Agency for Research on Cancer, and indeed some fulfil most of the excellence criteria…
Vertigo and multiple sclerosis: aspects of differential diagnosis.
2002
Equilibrium disorders caused by involvement of brainstem and cerebellar structures are common in patients with multiple sclerosis (MS), but peripheral conditions such as benign paroxysmal positional vertigo (BPPV) can be sometimes confused with those of a central origin. Therefore, an accurate otoneurologic investigation paying attention to differential diagnosis aspects should be performed in these subjects. Among available diagnostic tools, electro-oculography, posturography and vestibular evoked myogenic potentials (VEMPs) are especially suited to assess vestibulo-oculomotor and vestibulospinal systems. This paper briefly describes the most recent otoneurologic diagnostic strategies for …
Vertebrobasilar junction giant aneurysm: Lessons learned from a neurosurgical audit and anatomical investigation.
2015
The treatment of vascular lesions of the vertebrobasilar junction (VBJ) remains a challenging task in the neurosurgical practice and the gold standard therapy is still under debate. In this article, the authors report a detailed postmortem study of a VBJ giant aneurysm (GA) previously endovascularly treated. Although the decision-making process for the vast majority of neurosurgical treatment can nowadays be accurately carried out during the preoperative planning (i.e., with the aid of neuroimaging fusion protocols, neuronavigation platforms, etc.) meant to maximize the anatomical understanding of the lesions and minimize possible intraprocedural challenges, this postmortem study represents…
Nursing documentation of pressure ulcers in nursing homes: comparison of record content and patient examinations
2016
Aim The aim of this study was to describe the accuracy and quality of nursing documentation of the prevalence, risk factors and prevention of pressure ulcers, and compare retrospective audits of nursing documentation with patient examinations conducted in nursing homes. Design This study used a cross-sectional descriptive design. Method A retrospective audit of 155 patients' records and patient examinations using the European Pressure Ulcer Advisory Panel form and the Braden scale, conducted in January and February 2013. Results The prevalence of pressure ulcers was 38 (26%) in the audit of the patient records and 33 (22%) in patient examinations. A total of 17 (45%) of the documented press…
Independent component analysis on the mismatch negativity in an uninterrupted sound paradigm.
2008
We compared the efficiency of the independent component analysis (ICA) decomposition procedure against the difference wave (DW) and optimal digital filtering (ODF) procedures in the analysis of the mismatch negativity (MMN). The comparison was made in a group of 54 children aged 8-16 years. The MMN was elicited in a passive oddball protocol presenting uninterrupted auditory stimulation consisting of two frequent alternating tones (600 and 800 Hz) of 100 ms duration each. Infrequently, one of the 600 Hz tones was shortened to 50 or 30 ms. The event related potentials (ERPs) were decomposed into the MMN-like and non-MMN-like independent components (ICs) through the FastICA algorithm. The ICA …
Quality assurance in the treatment of colorectal cancer: the EURECCA initiative
2014
Colorectal cancer is one of the most common cancers in Europe. Over the past few decades, important advances have been made in screening, staging and treatment of colorectal cancer. However, considerable variation between and within European countries remains, which implies that further improvements are possible. The most important remaining question now is: when are we, health care professionals, delivering the best available care to patients with colon or rectal cancer? Currently, quality assurance is a major issue in colorectal cancer care and quality assurance awareness is developing in almost all disciplines involved in the treatment of colorectal cancer patients. Quality assurance has…

The electrocardiographic ‘triangular QRS-ST-T waveform’ pattern : a marker of severe haemodynamic compromise in Takotsubo syndrome : a case report
2020
Abstract Background Takotsubo cardiomyopathy is characterized by transient regional systolic dysfunction of the left ventricle, mimicking myocardial infarction. Although systolic left ventricular (LV) function normalizes in most cases, the outcome is not always favourable. Recently, a rare electrocardiogram (ECG) finding, lambda wave ST elevation or ‘triangular QRS-ST-T waveform’, was suggested as a possible marker of poor outcome in Takotsubo patients Case summary After a brief episode of chest pain and shortness of breath, a 67-year-old woman developed cardiogenic shock. Her resting ECG showed widespread ST elevations, which soon evolved into a pattern of triangular QRS-ST-T waveforms in …
