A 57-year-old woman with a stroke and left-sided pleural effusion
AbstractSevere hypothyroidism is associated with a wide spectrum of pulmonary and cardiovascular disorders. However, it rarely presents with pleural effusion. A 57-year-old woman presented with a stroke and left-sided pleural effusion was suspected of having hypertensive cardiomyopathy. During the treatment with diuretics, her renal function deteriorated and she developed a complete respiratory insufficiency, which led us to the definitive diagnosis. Therapy with thyroid hormone resulted in significant clinical improvement and the pleural effusion disappeared. Myxedema is easily missed when myxedema and pitting edema are simultaneously present in one subject. Severe hypothyroidism should be considered in the differential diagnosis of unexplained pleural effusion

Improving the Quality of EEG Data in Patients With Alzheimers Disease Using ICA
Does Independent Component Analysis (ICA) denature EEG
signals? We applied ICA to two groups of subjects (mild Alzheimer
patients and control subjects). The aim of this study was to examine
whether or not the ICA method can reduce both group di®erences and
within-subject variability. We found that ICA diminished Leave-One-
Out root mean square error (RMSE) of validation (from 0.32 to 0.28),
indicative of the reduction of group di®erence. More interestingly, ICA
reduced the inter-subject variability within each group (¾ = 2:54 in the
± range before ICA, ¾ = 1:56 after, Bartlett p = 0.046 after Bonfer-
roni correction). Additionally, we present a method to limit the impact
of human error (' 13:8%, with 75.6% inter-cleaner agreement) during
ICA cleaning, and reduce human bias. These ¯ndings suggests the novel
usefulness of ICA in clinical EEG in Alzheimer's disease for reduction of
subject variability

Keurmerken en labels voor verse Nederlandse vis : een wegwijzer voor kenniskringen in de visserij
Het project Kenniskringen in de Visserij is gericht op het beantwoorden van kennisvragen die door vissers samen met wetenschappers worden geformuleerd en die gerelateerd zijn aan verduurzaming van de visserij. Vanuit verschillende kenniskringen, en specifiek de kenniskring Flyshoot-visserij, kwam de vraag om meer inzicht te krijgen in de verschillende keurmerken voor verse vis. Welke keurmerken zijn er, wat betekenen deze keurmerken, hoe belangrijk zijn ze en hoe belangrijk zijn ze voor de visserspraktij
Forearm Rotation Range of Motion and Its Velocity in Eating With Chopsticks : a Comparison Among Positions of Dish
The purpose of this study was to determine range of motion of forearm rotation and its velocity in eating. Six young students (age:20.5±0.5 years [range:20-21], 2 men and 4 women) participated in this study. To measure three-dimensional motions, we used an electromagnetic tracking device system. The first sensor was attached to the dorsal/distal of forearm with sprint, and the second sensor was attached to the dorsal/medial ulna with elastic belt. The subjects ate pickles with chopsticks. At a wooden desk with 70cm height they sat on a height-adjustable chair, so their olecranon was as high as the desk top. Three positions of a dish were measured; A: at the distance of length of distal to elbow, B: at the distance of length of the upper extremity, and C: at a middle position between A and B. The results revealed that forearm rotation, range of motion and its velocity were significantly different among three conditions (one-way repeated-measure ANOVA)(p<0.05). Characteristically the motion velocity of B was lower than C, and A was lower than C (p<0.05). Findings suggest that 1) limited forearm range of motion would decrease a burden of forearm by setting a dish at B or C than A, 2) the rotation (maximal pronation and supination: 11 and 49 degrees, respectively) was similar, to a fork (maximal pronation and supination: 10 and 51 degrees, respectively), 3) C may be efficiently operated, and 4) the system may be instructed as a good equipment for eating
Eficacia de dexketoprofeno versus tramadol como analgesia preventiva en Anestesia General Balanceada
El dolor postoperatorio los pacientes lo aceptaban como una experiencia desagradable e inevitable, uno de los peor tratados, el control del mismo es primordial para los pacientes sometidos a cirugías abdominales.
Su principio es simple y consiste en administrar un analgésico preoperatoriamente antes de la incisión quirúrgica ya que puede prevenir o reducir la hipersensibilidad de las neuronas del asta dorsal para reducir o eliminar el dolor subsiguiente.
Este mal control del dolor post operatorio está asociado a una variedad de consecuencias negativas, que incluyen alteraciones cardíacas e incremento del riesgo de isquemia o infarto al miocardio, complicaciones tromboembólicas y pulmonares, alteraciones inmunes, deprivación del sueño y trastornos psicológicos como ansiedad y depresión, incrementa el riesgo de dolor postoperatorio persistente, necesidad de rehabilitación, incrementa la estancia hospitalaria o reingreso y disminuye la calidad de vida de quien la padec
Providing perioperative care for patients with hip fractures
Providing perioperative care for patients with hip fractures can present major challenges for the anaesthesiologist. These patients often have multiple comorbidities, the deterioration of any one of which may have precipitated the fall. A careful balance has to be achieved between minimising the time before operation and spending time to optimise their medical status. This review will present insights into preoperative patient assessment and optimization in this group of patients from the anaesthesiologists’ perspective. In particular, it will highlight important medical issues of concern that may alter anaesthetic risks and management. With a greater understanding of what these issues are, potentially a more prompt and integrated approach to managing these patients may be made. Hopefully, this would result in minimising last minute cancellations due to medical reasons for these patients
Multiway Array Decomposition Analysis of EEGs in Alzheimer’s Disease
Methods for the extraction of features from physiological datasets are growing needs as clinical investigations of Alzheimer’s disease (AD) in large
and heterogeneous population increase. General tools allowing diagnostic regardless of recording sites, such as different hospitals, are essential and if combined to
inexpensive non-invasive methods could critically improve mass screening of subjects with AD. In this study, we applied three state of the art multiway array
decomposition (MAD) methods to extract features from electroencephalograms (EEGs) of AD patients obtained from multiple sites. In comparison to MAD,
spectral-spatial average filter (SSFs) of control and AD subjects were used as well as a common blind source separation method, algorithm for multiple unknown
signal extraction (AMUSE). We trained a feed-forward multilayer perceptron (MLP) to validate and optimize AD classification from two independent databases.
Using a third EEG dataset, we demonstrated that features extracted from MAD outperformed features obtained from SSFs AMUSE in terms of root mean squared
error (RMSE) and reaching up to 100% of accuracy in test condition. We propose that MAD maybe a useful tool to extract features for AD diagnosis offering great
generalization across multi-site databases and opening doors to the discovery of new characterization of the disease
