Differences between IEC 60601-1 and IEC 62353 IEC 60601-1 is a type-testing standard describing the design criteria of ME EQUIPMENT which should be proven by applying a combination of stress and destructive tests. In addition, IEC 60601-1 specifies that these tests are carried out under certain environmental conditions. These laboratory conditions cannot be guaranteed whilst testing ME EQUIPMENT in-service. Therefore, measurements requiring certain environmental conditions can only be applied consistently with difficulty and are therefore not suitable for use during in-service testing of equipment. An additional aspect is that equipment could potentially be damaged during test applications and can face a potential danger to person(s) and surroundings.
Another aspect of the design process of ME EQUIPMENT is to ensure the safety of the equipment during its expected useful life. The selection of methods and materials should contribute in this way.
As far as possible, a consensus is required to harmonize the assessment of the safe operation and testing of ME EQUIPMENT and ME SYSTEMS whilst respecting local requirements and meeting increasing demands for risk management. It is therefore necessary to describe tests beyond those of the type testing and to provide a uniform and unambiguous means of assessing the equipment's safety whilst maintaining the relation to IEC 60601-1 and minimizing the risk of hazard to the person conducting the assessment.
All these aspects were considered during the creation of IEC 62353.
IEC 62353 primarily defines the requirements for ensuring the ELECTRICAL SAFETY of ME EQUIPMENT and ME SYSTEMS prior to PUTTING INTO SERVICE, during RECURRENT TESTING and after REPAIR whilst respecting the IEC 60601-1 design criteria and providing means of safer working practice to those persons involved in assessing the safety of ME EQUIPMENT and/or ME SYSTEMS.
In addition, IEC 62353 provides means to assess the aging process of ME EQUIPMENT and/or ME SYSTEMS through structured and regular INSPECTIONS.
A selection of test procedures, test methods and test intervals which can be used during the expected useful life of ME EQUIPMENT and ME SYSTEMS is described herein.

HOW DOES THE FEMORAL CORTEX DEPEND ON BONE SHAPE? A METHODOLOGY FOR THE JOINT ANALYSIS OF SURFACE TEXTURE AND SHAPE
A.H. Gee, G.M. Treece and K.E.S. Poole
15 June 2017
In humans, there is clear evidence of an association between hip fracture risk and femoral neck bone mineral density, and some evidence of an association between fracture risk and the shape of the proximal femur. Here, we investigate whether the femoral cortex plays a role in these associations: do particular morphologies predispose to weaker cortices? To answer this question, we used cortical bone mapping to measure the distribution of cortical mass surface density (CMSD, mg/cm2) in a cohort of 125 females. Principal component analysis of the femoral surfaces identified three modes of shape variation accounting for 65% of the population variance. We then used statistical parametric mapping (SPM) to locate regions of the cortex where CMSD depends on shape, allowing for age. Our principal findings were increased CMSD with increased gracility over much of the proximal femur; and decreased CMSD at the superior femoral neck, coupled with increased CMSD at the calcar femorale, with increasing neck-shaft angle.
In obtaining these results, we studied the role of spatial normalization in SPM, identifying systematic misregistration as a major impediment to the joint analysis of CMSD and shape. Through a series of experiments on synthetic data, we evaluated a number of registration methods for spatial normalization, concluding that only those predicated on an explicit set of homologous landmarks are suitable for this kind of analysis. The emergent methodology amounts to an extension of Geometric Morphometric Image Analysis to the domain of textured surfaces, alongside a protocol for labeling homologous landmarks in clinical CT scans of the human proximal femur.

UFSCar busca voluntários idosos para estudo da dor crônica Publicado em 20-02-2018 13:00
Uma pesquisa na UFSCar pretende avaliar a combinação entre a educação em Neurociência da dor e o pilates para a diminuição da dor crônica em pacientes idosos. O estudo "Educação em Neurociência da dor e pilates para idosos com dor lombar crônica: ensaio clínico randomizado controlado" é desenvolvido pela doutoranda E.R., sob orientação de docente do DEnf, e coorientação de professor do DGero. O trabalho é realizado em parceria entre os programas de pós-graduação em Enfermagem (PPGEnf) e em Gerontologia (PPGGero) da Universidade.
A educação em Neurociência da dor consiste, em linhas gerais, em ensinar o paciente a compreender o processo fisiológico da dor e encará-la como um mecanismo de sobrevivência cujo propósito é proteger o corpo, além de implicar em mostrar que a dor está no cérebro e não é apenas uma sensação física.
O objetivo do estudo é analisar o efeito da educação em Neurociência da dor combinada à prática do pilates em comparação com a aplicação somente do pilates em idosos com dor lombar crônica.
Para desenvolver o estudo, estão sendo recrutados voluntários, homens ou mulheres, a partir de 60 anos de idade, que tenham dor lombar há mais de seis meses. Os participantes
vão passar por sessões gratuitas de pilates, somadas à terapia complementar, para ajudar no controle da dor, durante oito semanas. Os interessados podem entrar em contato com a pesquisadora até o dia 4 de agosto de 2018 por e-mail ou por telefone.
