TRUNK POSTURE AND STATICO-DYNAMICAL SPINE ANALYSIS– COMPARING ULTRASOUND BASED VS. OPTICALLY BASED MEASUREMENT SYSTEM

The purpose of this study was to compare two different methods measuring trunk posture and statico-dynamical spine analysis. 32 patients participated in this cross sectional study. Comparing measured values a wide congruence could be demonstrated with marginal underestimating in kyphosis and lordosis data for the ultrasound based system. The largest deviation could be shown for pelvic obliquity measured in mm. Trunk inclination, vertical deflection and pelvic obliquity measured in degree showed proper analogy for both measuring systems. Validity, reliability based on particular technical principles could be verified

Navigating 'ethics in practice': An ethnographic case study with young women living with HIV in Zambia.

While 'procedural ethics' provides essential frameworks for governing global health research, reflecting on 'ethics in practice' offers important insights into addressing ethically important moments that arise in everyday research. Particularly for ethnographic research, renowned for it's fluid and spontaneous nature, engaging with 'ethics in practice' has the potential to enhance research practice within global health. We provide a case study for such reflexivity, exploring 'ethics in practice' of ethnographic research with middle-income young women living with HIV in Lusaka, Zambia. We explore the ethical issues arising from the layered interaction of the population (young women), the disease under investigation (HIV), the method of study (ethnographic), and the setting (Zambia, a lower middle income country). We describe how we navigated five key practical ethical tensions that arose, namely the psycho-emotional benefits of the research, the negotiated researcher-participant relationship, protecting participants' HIV status, confidentiality and data ownership, and researcher obligations after the end of the research. We exemplify reflexive engagement with 'ethics in practice' and suggest that engaging with ethics in this way can make important contributions towards developing more adequate ethical guidelines and research practice in global public health

Moregrasp: Restoration of Upper Limb Function in Individuals with High Spinal Cord Injury by Multimodal Neuroprostheses for Interaction in Daily Activities

The aim of the MoreGrasp project is to develop a noninvasive, multimodal user interface including a brain-computer interface (BCI) for intuitive control of a grasp neuroprosthesis to support individuals with high spinal cord injury (SCI) in everyday activities. We describe the current state of the project, including the EEG system, preliminary results of natural movements decoding in people with SCI, the new electrode concept for the grasp neuroprosthesis, the shared control architecture behind the system and the implementation of a user-centered design

Dimensions of Researcher Vulnerability in Qualitative Health Research and Recommendations for Future Practice

Publisher Copyright: © The Author(s) 2023.Vulnerability has typically been addressed in the context of research ethics from the point of view of participants, with a focus on how to prevent the potential or exacerbation of existing harm caused by the power and role asymmetries between researchers and participants. However, more recent approaches to research ethics question whether researchers are, by definition, located in a privileged position during the research process and safe from any kind of vulnerability. In line with this, we reflect on the dimensions of researcher vulnerability specific to studies using a qualitative methodology in health research. Our argument is that participants and researchers should be on the receiving end of efforts to implement ethical procedures and protection from harm. Based on the autoethnographic analysis of our experiences as qualitative health researchers, this paper aims to identify dimensions of researcher vulnerability, and draw out relevant recommendations for practice. The reflections upon which this paper is based emerged during a spring school focusing on research ethics in qualitative health research, during which we discussed situations from our own research experience which left us feeling vulnerable. We identify four dimensions related to the experience of vulnerability (reciprocity; emotional labor; application of ethical standards; reversed power asymmetries) and five crosscutting aspects relating to these dimensions (researching sensitive topics; researching in contexts of vulnerability, poverty and structural violence; being a novice; lacking adequate support; insufficient time and space for ethical reflexivity). Our recommendations address particular challenges for these dimensions, and center on the role of reflexivity, as one of the cornerstones for enabling ethical qualitative research practice, requiring us to acknowledge and address our own vulnerability and positionality. Autoethnographic exercises are particularly useful for zooming in on ethically important moments in research related to researcher vulnerability and fruitful for identifying resources to respond to such challenges in the future.publishersversionpublishe

The use of high-throughput sequencing to investigate an outbreak of glycopeptide-resistant Enterococcus faecium with a novel quinupristin-dalfopristin resistance mechanism.

High-throughput sequencing (HTS) has successfully identified novel resistance genes in enterococci and determined clonal relatedness in outbreak analysis. We report the use of HTS to investigate two concurrent outbreaks of glycopeptide-resistant Enterococcus faecium (GRE) with an uncharacterised resistance mechanism to quinupristin-dalfopristin (QD).Seven QD-resistant and five QD-susceptible GRE isolates from a two-centre outbreak were studied. HTS was performed to identify genes or predicted proteins that were associated with the QD-resistant phenotype. MLST and SNP typing on HTS data was used to determine clonal relatedness.Comparative genomic analysis confirmed this GRE outbreak involved two distinct clones (ST80 and ST192). HTS confirmed the absence of known QD resistance genes, suggesting a novel mechanism was conferring resistance. Genomic analysis identified two significant genetic determinants with explanatory power for the high level of QD resistance in the ST80 QD-resistant clone: an additional 56aa leader sequence at the N-terminus of the lsaE gene and a transposon containing seven genes encoding proteins with possible drug or drug-target modification activities. However, HTS was unable to conclusively determine the QD resistance mechanism and did not reveal any genetic basis for QD resistance in the ST192 clone. This study highlights the usefulness of HTS in deciphering the degree of relatedness in two concurrent GRE outbreaks. Although HTS was able to reveal some genetic candidates for uncharacterised QD resistance, this study demonstrates the limitations of HTS as a tool for identifying putative determinants of resistance to QD
