“I want to fit in… but I don’t want to change myself fundamentally”: A qualitative exploration of the relationship between masking and mental health for autistic teenagers

BackgroundPrevious research has identified an association between masking and mental health for autistic people. However, the direction of causality and mechanisms involved in this relationship are not well understood. This qualitative study aimed to investigate autistic teenagers’ experiences of masking, mental health and how the two develop and interact.MethodsTwenty autistic teenagers took part in a semi-structured interview. The interviews were analysed using Reflexive Thematic Analysis.ResultsFrom the analysis, one theme was identified to conceptualise masking as described by participants. Five more inter-related themes were identified, each involved both in the relationship between masking and mental health and conversely in the relationship between authenticity and mental health. Participants described how masking and mental health both influence each other, and both are influenced by social and environmental factors.ConclusionsThe findings are consistent with previous research indicating that masking is associated with mental health difficulties. Our analysis presents a broader conceptualisation of masking than previously defined in the literature, placing social oppression of autistic people at the heart of the relationship between masking and mental health. The findings have implications for diagnostic services, post-diagnostic support and therapeutic interventions, highlighting the need to challenge deficit-based narratives of autism.     

Integrative qualitative communication analysis of consultation and patient and practitioner perspectives: towards a theory of authentic caring in clinical relationships

Objective

We developed a method whereby relationships can be studied simultaneously from the perspectives of each party and researchers’ observations of their dialogue. Then we used this method to study how to recognise authentic, caring clinical relationships.

Methods

Participants were 20 patients who had recently received surgery for breast cancer and nine surgeons with whom they had a post-operative consultation. We audiorecorded consultations, before interviewing patients and surgeons about their perceptions of the consultation and each other. Cross-case qualitative analyses (analysing consultations and surgeon and patient interviews, respectively) were supplemented by integrative, within-case analysis.

Results

Surgeons and patients described their relationship as personal and emotional, but emotional talk was absent from consultations. For patients and surgeons, their relationship depended, instead, on surgeons’ expertise and character.

Conclusion

Our integrative approach suggested that authentic caring in these relationships lay in practitioners’ conscientious execution of their role and, contrary to currently influential views, not in an explicit emotional engagement.

Practice implications

Relationships between patients and practitioners cannot be described adequately using analyses of interactions between them. Researchers will need to triangulate between these observations and the patient and practitioner perspectives in order to understand what makes for authentically caring relationships.     

Authenticity: a concept analysis

PURPOSE: This paper aims to analyze the concept of authenticity and propose a definition of authenticity that can be used to enhance the nurse-client relationship. SOURCES: Published research. CONCLUSIONS: Authenticity is a life-long process of self-discovery that includes realizing personal potential and acting on that potential. A part of this process is accepting the responsibility for and the consequences of life choices that are consciously or unconsciously made. This is sometimes achieved through suffering. This process culminates in a demonstration of congruency in ideals, values, and actions in relation to self and others.     

云南昭通不同产地天麻质控成分的含量测定

目的以天麻的质控成分天麻素(gastrodin,GAS)及对羟基苯甲醇(p-hydroxybenzyl alcohol,HBA)含量为指标对云南昭通不同产地的天麻进行考察,以确定其最佳产地。方法选取昭通境内彝良小草坝、镇雄盐源、威信水田3个产地的乌天麻,用95%乙醇进行回流提取,计算其提取率;采用HPLC分析方法测定天麻醇提取物中质控成分GAS及HBA的含量,进行天麻最佳产地的初步评价。结果彝良小草坝、镇雄盐源、威信水田的天麻醇提取物的提取率分别为:17.9、9.2、10.5%,所含质控成分的总量(GAS+HBA)分别为:0.8119、0.2478、0.2022%。结论通过分析,云南昭通境内的彝良小草坝产地的天麻醇提取物的提取率及质控成分总量均为三者中最高,可认为该地为天麻道地药材的最佳产地之一。

Providing Integrity,Authenticity, and Confidentiality for Header and Pixel Data of DICOM Images

Exchange of medical images over public networks is subjected to different types of security threats. This has triggered persisting demands for secured telemedicine implementations that will provide confidentiality, authenticity, and integrity for the transmitted images. The medical image exchange standard (DICOM) offers mechanisms to provide confidentiality for the header data of the image but not for the pixel data. On the other hand, it offers mechanisms to achieve authenticity and integrity for the pixel data but not for the header data. In this paper, we propose a crypto-based algorithm that provides confidentially, authenticity, and integrity for the pixel data, as well as for the header data. This is achieved by applying strong cryptographic primitives utilizing internally generated security data, such as encryption keys, hashing codes, and digital signatures. The security data are generated internally from the header and the pixel data, thus a strong bond is established between the DICOM data and the corresponding security data. The proposed algorithm has been evaluated extensively using DICOM images of different modalities. Simulation experiments show that confidentiality, authenticity, and integrity have been achieved as reflected by the results we obtained for normalized correlation, entropy, PSNR, histogram analysis, and robustness.
