In this work, we report the published cases of human and porcine cysticercosis, as well as Taenia solium taeniasis diagnosed in Mexico during the last 10 years. Numerical data allow us to state that this disease remains as a public health problem in our country. Whereas efficient tools have been developed for the diagnosis and prevention of cysticercosis, we strongly recommend further measures allowing the control and eventual eradication of this parasite in Mexico.

Job satisfaction has been linked to performance and, in the health services, to the quality of the care being given. Objectives: To establish the job satisfaction grade and to identify the factors associated to it in nursing staff of four tertiary care public health institutions. Material and methods: Cross-sectional, observational, and descriptive study. The sample comprised 594 nursing professionals. A survey was applied, it consisted of two sections, one of socio-demographic data and the other to measure the intrinsic and extrinsic factor relate to job satisfaction in accordance to the extended Font Roja questionnaire (9 factors with 26 total items). Results: instrument reliability with a cronbach's alpha value of 0.8 was obtained. 35% of the respondents are specialized personnel; the job satisfaction score had a global mean of 101±10. Factor associated with dissatisfaction were job promotion and professional competence, factors with highest marks were interpersonal relationship with boss and workmates. Extrinsic factors did not show statistically significant differences. Discussion: results are consistent with theliterature; professional promotion and job competence are the most affected factors. Institution "C" has the highest ranks in job satisfaction, the fact that a professional working in critical areas is more satisfied is highlighted too. Conclusions: nursing staff in the surveyed institutions have a medium to high level of job satisfaction, the identification of dissatisfaction and satisfaction factors is important to establish improvements in the health care quality. © INNN, 2013.

In this work, we present a fast and robust method for lesions detection, primarily, a non-linear image enhancement is performed on T1 weighted magnetic resonance (MR) images in order to facilitate an effective segmentation that enables the lesion detection. First a dynamic system that performs the intensity transformation through the Modified sigmoid function contrast stretching is established, then, the enhanced image is used to classify different brain structures including the lesion using constrained fuzzy clustering, and finally, the lesion contour is outlined through the level set evolution. Through experiments, validation of the algorithm was carried out using both clinical and synthetic brain lesion datasets and an 84%-93% overlap performance of the proposed algorithm was obtained with an emphasis on robustness with respect to different lesion types. © 2014 SPIE.

Virtual rehabilitation supports motor training following stroke by means of tailored virtual environments. To optimize therapy outcome, virtual rehabilitation systems automatically adapt to the different patients' changing needs. Adaptation decisions should ideally be guided by both the observable performance and the hidden mind state of the user. We hypothesize that some affective aspects can be inferred from observable metrics. Here we present preliminary results of a classification exercise to decide on 4 states; tiredness, tension, pain and satisfaction. Descriptors of 3D hand movement and finger pressure were collected from 2 post-stroke participants while they practice on a virtual rehabilitation platform. Linear Support Vector Machine models were learnt to unfold a predictive relation between observation and the affective states considered. Initial results are promising (ROC Area under the curve (mean±std): 0.713 ± 0.137). Confirmation of these opens the door to incorporate surrogates of mind state into the algorithm deciding on therapy adaptation. © 2015 ICST. Source

All-trans retinoic acid (ATRA) promotes the endogenous expression of both nerve growth factor (NGF) and retinoic acid receptor beta (RAR-β). We have previously shown that the administration of ATRA partly reverts the damage induced by diabetic neuropathy (DN). In this investigation, we evaluated the effects of vitamin A, a commercial, inexpensive compound of retinoic acid, on the therapy of DN. A total of 70 rats were randomized into 4 groups. Group A was the control, and groups B, C, and D received a total dose of 60 mg/kg streptozotocin intraperitoneally. When signs of DN developed, groups C and D were treated either with vitamin A (20,000 IU) or with ATRA 25 mg/kg for 60 days. Plasma glucose, contents of NGF, thermal and nociceptive tests, and RAR-β expression were evaluated. All diabetic rats developed neuropathy. The treatment with vitamin A and ATRA reverted similarly the sensorial disturbances, which was associated with increased contents of NGF and RAR-β expression. Our results indicate that the administration of vitamin A has the same therapeutic effect as ATRA on peripheral neuropathy and suggest its potential therapeutic use in patients with diabetes. © 2014 Mosby, Inc.
