In prehospital setting, the patient‘s home is the most often place where is supplied resuscitation care. Method We applied an online questionnaire to 116 nurses and physicians who work in prehospital setting. Results Of the 116 professionals surveyed, 49 were physician’s (42,7%) and 67 (57,3%) were nurses. At mobile medical car work 93 professionals: 44 nurses (65,7%) and 49 physicians (100%). From the remaining nurses, 18 (26,9%) work at an immediate life support ambulance and the other 5 (7,5%) at another resource. All the professionals said they provided care in the prehospital with the presence of family members. 31% have a favourable opinion (12,3% physicians vs 44,8% nurses) about the presence of family members and 49,3% have an unfavourable opinion (71,4% physicians vs 32,9% nurses). They said that the main advantages are obtaining the health history, recognition of the team effort and facilitating the grieving process. The disadvantages there may be interference from family in procedures, the stress experienced by the team for being watched and anxiety felt by the family. Conclusion Most nurses have a positive opinion about the presence of family members during resuscitation as long as they are able to perceive the significance of interventions in resuscitation situations and do not interfere with team performance. On the other hand, most physicians have an opinion against, mainly due to the distraction of the team during all procedures and the trauma to the family with the invasive procedures.

Medical data and in particular medical images have increasing storage space and remote access requirements. Cloud computing satisfies these requirements but unclear safeguards on data security can expose sensitive data to possible attacks. Furthermore, recent changes in legislation imposed additional security constraints in technology to ensure the privacy of individuals and the integrity of data when stored in the cloud. In contrast with this trend, current data security methods, based on encryption, create an additional overhead to the performance, and often they are not allowed in public cloud servers. Hence, this paper proposes a mechanism that combines data fragmentation to protect medical images on the public cloud servers, and a NoSQL database to secure an efficient organisation of such data. Results of this paper indicate that the latency of the proposed method is significantly lower if compared with AES, one of the most adopted data encryption mechanisms. Therefore, the proposed method is an optimal trade-off in environments with low latency requirements or limited resources.

It allows companies to save costs on infrastructure and maintenance and to focus on the development of products. However, this fast-growing paradigm has brought along some concerns from users, such as the integrity and security of the data, particularly in environments where users rely entirely on providers to secure their data. This paper explores different techniques to fragment data on the cloud and prevent direct unauthorised access to the data. It explores their performance on a cloud instance, where the total time to perform the operation, including the upload and download of the data, is considered. Results from this experiment indicate that fragmentation algorithms show better performance compared to encryption. Moreover, when combining encryption with fragmentation, there is an increase in the security, with the trade-off of the performance.

Both of these tick-borne pathogens hamper livestock production and cause a significant economic impact. Although buffaloes have demonstrated a high level of adaptability, data on tick-borne pathogens are scarcely reported in Brazil. Thus, the aim of this study was to screen water buffaloes from the state of Maranhão for piroplasm and A. marginale occurrence using PCR assays. All samples were negative for A. marginale. One of the 287 (0.35%) water buffaloes tested was positive for Theileria sp. Sequencing of the 18S rDNA fragment (356 bp) showed that the Theileria sp. identified was closely related to the T. buffeli /orientalis group. Future studies on the clinical signs of infection and the main vector in this country are needed.
