Design and introduction of a quality of life assessment and practice support system: perspectives from palliative care settings
Background:
Quality of life (QOL) assessment instruments, including patient-reported outcome measures (PROMs) and patient-reported experience measures (PREMs), are increasingly promoted as a means of enabling clinicians to enhance person-centered care. However, integration of these instruments into palliative care clinical practice has been inconsistent. This study focused on the design of an electronic Quality of Life and Practice Support System (QPSS) prototype and its initial use in palliative inpatient and home care settings. Our objectives were to ascertain desired features of a QPSS prototype and the experiences of clinicians, patients, and family caregivers in regard to the initial introduction of a QPSS in palliative care, interpreting them in context.
Methods:
We applied an integrated knowledge translation approach in two stages by engaging a total of 71 clinicians, 18 patients, and 17 family caregivers in palliative inpatient and home care settings. Data for Stage I were collected via 12 focus groups with clinicians to ascertain desirable features of a QPSS. Stage II involved 5 focus groups and 24 interviews with clinicians and 35 interviews with patients or family caregivers during initial implementation of a QPSS. The focus groups and interviews were recorded, transcribed, and analyzed using the qualitative methodology of interpretive description.
Results:
Desirable features focused on hardware (lightweight, durable, and easy to disinfect), software (simple, user-friendly interface, multi-linguistic, integration with e-health systems), and choice of assessment instruments that would facilitate a holistic assessment. Although patient and family caregiver participants were predominantly enthusiastic, clinicians expressed a mixture of enthusiasm, receptivity, and concern regarding the use of a QPSS. The analyses revealed important contextual considerations, including: (a) logistical, technical, and aesthetic considerations regarding the QPSS as a technology, (b) diversity in knowledge, skills, and attitudes of clinicians, patients, and family caregivers regarding the integration of electronic QOL assessments in care, and (c) the need to understand organizational context and priorities in using QOL assessment data.
Conclusion:
The process of designing and integrating a QPSS in palliative care for patients with life-limiting conditions and their family caregivers is complex and requires extensive consultation with clinicians, administrators, patients, and family caregivers to inform successful implementation

Development of Computational Tools for the Inference of Protein Interaction Specificity Rules and Functional Annotation Using Structural Information
Relatively few protein structures are known, compared to the enormous amount of sequence data produced in the sequencing of different genomes, and relatively few
protein complexes are deposited in the PDB with respect to the great amount of
interaction data coming from high-throughput experiments (two-hybrid or affinity
purification of protein complexes and mass spectrometry). Nevertheless, we can rely
on computational techniques for the extraction of high-quality and information-rich
data from the known structures and for their spreading in the protein sequence space.
We describe here the ongoing research projects in our group: we analyse the protein
complexes stored in the PDB and, for each complex involving one domain belonging
to a family of interaction domains for which some interaction data are available, we
can calculate its probability of interaction with any protein sequence. We analyse the
structures of proteins encoding a function specified in a PROSITE pattern, which
exhibits relatively low selectivity and specificity, and build extended patterns. To
this aim, we consider residues that are well-conserved in the structure, even if their
conservation cannot easily be recognized in the sequence alignment of the proteins
holding the function. We also analyse protein surface regions and, through the
annotation of the solvent-exposed residues, we annotate protein surface patches via a
structural comparison performed with stringent parameters and independently of the
residue order in the sequence. Local surface comparison may also help in identifying
new sequence patterns, which could not be highlighted with other sequence-based
methods

Investigations on the Usefulness of CEACAMs as Potential Imaging Targets for Molecular Imaging Purposes
Members of the carcinoembryonic antigen cell adhesion molecules (CEACAMs) family are the prototype of tumour markers. Classically they are used as serum markers, however, CEACAMs could serve as targets for molecular imaging as well.
In order to test the anti CEACAM monoclonal antibody T84.1 for imaging purposes, CEACAM expression was analysed using this antibody. Twelve human cancer cell lines from different entities were screened for their CEACAM expression using qPCR, Western Blot and FACS analysis. In addition, CEACAM expression was analyzed in primary tumour xenografts of these cells. Nine of 12 tumour cell lines expressed CEACAM mRNA and protein when grown in vitro. Pancreatic and colon cancer cell lines showed the highest expression levels with good correlation of mRNA and protein level. However, when grown in vivo, the CEACAM expression was generally downregulated except for the melanoma cell lines. As the CEACAM expression showed pronounced expression in FemX-1 primary tumours, this model system was used for further experiments. As the accessibility of the antibody after i.v. application is critical for its use in molecular imaging, the binding of the T84.1 monoclonal antibody was assessed after i.v. injection into SCID mice harbouring a FemX-1 primary tumour. When applied i.v., the CEACAM specific T84.1 antibody bound to tumour cells in the vicinity of blood vessels. This binding pattern was particularly pronounced in the periphery of the tumour xenograft, however, some antibody binding was also observed in the central areas of the tumour around blood vessels. Still, a general penetration of the tumour by i.v. application of the anti CEACAM antibody could not be achieved despite homogenous CEACAM expression of all melanoma cells when analysed in tissue sections. This lack of penetration is probably due to the increased interstitial fluid pressure in tumours caused by the absence of functional lymphatic vessels.Germany.

Mothering, Albinism and Human Rights: The Disproportionate Impact of Health-Related Stigma in Tanzania
In many parts of sub-Saharan Africa, mothers impacted by the genetic condition of albinism, whether as mothers of children with albinism or themselves with albinism, are disproportionately impacted by a constellation of health-related stigma, social determinants of health (SDH), and human rights violations. In a critical ethnographic study in Tanzania, we engaged with the voices of mothers impacted by albinism and key stakeholders to elucidate experiences of stigma. Their narratives revealed internalized subjective stigma, social stigma such as being ostracized by family and community, and structural stigma on account of lack of access to SDH. An analysis of health systems as SDH revealed stigmatizing attitudes and behaviours of healthcare providers, especially at the time of birth; a lack of access to timely quality health services, in particular skin and eye care; and a lack of health-related education about the cause and care of albinism. Gender inequality as another SDH featured prominently as an amplifier of stigma. The findings pose implications for research, policy, and practice. A concrete avenue to de-stigmatization of mothers impacted by albinism exists by the application of principles of human rights, particularly equality and non-discrimination; contextual analysis of cultural dynamics including relevant ontology; meaningful participation of rights-claimants, such as peer groups of mothers; and accountability of governments and their obligation to ensure access to health information as a key social determinant of the right to health
Mapping a research-advocacy-policy agenda on human rights and albinism: a mixed methods project
Background: Persons with albinism face challenges to their wellbeing, safety, and security, ranging from vision impairment and skin cancer to stigma and discrimination. In some regions, they also face human rights atrocities including mutilation and murder. Research on human rights and albinism is a relatively new field that has gained momentum since the United Nations appointment of an Independent Expert on the enjoyment of human rights by persons with albinism. In this paper, we present the results of a mixed methods study undertaken to identify priorities for research, advocacy, and policy on albinism and human rights. Methods: The first component was a synthesis of peer-reviewed and grey literatures at the nexus of albinism, spiritual/cultural beliefs and practices, and human rights. We then conducted a priority-setting survey, informed by Delphi methods, on extant knowledge-practice gaps and research, advocacy, and policy priorities. Inclusion criteria included demonstrated expertise in the field (e.g., peer-reviewed publications, funded research), membership on national or international associations, or advocacy (civil society organizations) of more than 2 years in albinism and human rights. Thereafter, we gathered leading researchers, policy-makers, and civil society stakeholders for a Roundtable to gain consensus on these priorities. Results: Access to skin and vision care, and education were not deemed high priority for research, likely because the evidence supporting the need for these is well established. However, they were priorities for advocacy and policy: what is needed is mobilization of this evidence through advocacy and implementation of such services (policy). Other social determinants of health (rurality, poverty, and gender equality) are present as subtext in the findings, more so than priorities for research, advocacy, or policy, despite their preponderance in the lives of persons with albinism. Research was prioritized on stigma and discrimination; advocacy; and witchcraft, but with some differentiation between Global North and Global South priorities. Priorities for research, advocacy, and policy vary in keeping with the explanatory frameworks at play, including how harmful practices and witchcraft are viewed. Conclusions: The lived experience of albinism is profoundly shaped by the social determinants of health (SDOH). Threats to the security and well-being of persons with albinism should be viewed through a human rights lens that encompasses the explanatory frameworks at play
