- The MM500 study is an initiative to map the protein levels in malignant melanoma tumor samples, focused on in-depth histopathology coupled to proteome characterization. The protein levels and localization were determined for a broad spectrum of diverse, surgically isolated melanoma tumors originating from multiple body locations. More than 15,500 proteoforms were identified by mass spectrometry, from which chromosomal and subcellular localization was annotated within both primary and metastatic melanoma. The data generated by global proteomic experiments covered 72% of the proteins identified in the recently reported high stringency blueprint of the human proteome. This study contributes to the NIH Cancer Moonshot initiative combining detailed histopathological presentation with the molecular characterization for 505 melanoma tumor samples, localized in 26 organs from 232 patients.

- Angiotensin II has been suggested to influence central dopamine and serotonin turnover. Since the angiotensin-converting enzyme (ACE) plays a key role in angiotensin regulation by converting inactive angiotensin 1 to active angiotensin II, we hypothesised that the functional insertion/deletion (I/D) polymorphism in the ACE gene, which has previously been suggested to be associated with, depression and panic disorder, may influence monoamine activity. A well-established technique for assessing brain monoamine turnover in humans is to measure concentrations of monoamine metabolites in the cerebrospinal fluid (CSF). We thus investigated possible associations between the ACE I/D polymorphism and CSF monoamine metabolite concentrations in a population of healthy male subjects. After having found such an association between the ACE I/D polymorphism and CSF levels of the dopamine metabolite homovanillic acid and the serotonin metabolite 5-hydroxyindoleacetic acid in this sample, I carriers displaying lower levels, we tried to replicate this observation in a population of violent male offenders from which also both CSF and DNA were available. Also in this sample, the same associations were found. Our results suggest that the ACE I/D polymorphism may play a role in the modulation of serotonergic and dopaminergic turnover in men.

- PURPOSE: To report our experience of liver embolization with trisacryl gelatin microspheres (Embospheretrade mark) in patients with metastatic neuroendocrine tumors. MATERIAL AND METHODS: Fifteen patients underwent selective embolization of the right or left hepatic artery with Embosphere. One lobe was embolized in seven patients and both lobes, on separate occasions, in eight patients. Seven patients had midgut carcinoids, two had lung carcinoids, one suffered from a thymic carcinoid, and five had endocrine pancreatic tumors. Eight patients suffered from endocrine symptoms, seven of whom had carcinoid syndrome and one WDHA (watery diarrhea, hypokalemia, achlorhydria) syndrome. RESULTS: Partial radiological response was seen after eight embolizations (in six different patients), stable disease was observed after 13 embolizations (after three of these, necroses occurred), while radiological progression was noted after only two embolizations. Only two patients experienced a biochemical response. Clinical improvement of carcinoid syndrome was observed after five embolizations. There were no major complications. Fever >38 degrees C was seen after all but four embolizations, and urinary tract infections were diagnosed after eight embolizations. CONCLUSION: Selective hepatic artery embolization with Embosphere particles is a safe treatment for patients with metastatic neuroendocrine tumors and may lead to partial radiological response as well as symptomatic improvement of disabling endocrine symptoms.

Being perceived as a ‘visitor’ in the nursing staff’s working arena : the involvement of relatives in daily caring activities in nursing homes in an urban community in Sweden

- BackgroundIt is both complex and difficult for relatives when a loved one moves into a nursing home and many relatives are not prepared for the realities these new situations entail. Little attention has been paid to scrutinising the involvement of relatives in patient care, particularly in relation to the structures and routines of nursing homes or to the staff's reasoning concerning their involvement.AimTo describe, from a gender perspective, how nursing staff's routines and reasoning act to condition the involvement of relatives in nursing homes.MethodsFocused ethnographic fieldwork was conducted in a medium-sized urban community in central Sweden in three different nursing homes.ResultsThe nursing staff assigns a certain code of conduct to all relatives they perceived as ‘visitors’ in their working arena. This code of conduct was related to the routines and subcultures existing among the nursing staff and stemmed from a division of labour; the underlying concept of ‘visitor’ predetermined the potential for relatives' involvement. This involvement is explicitly related to the general gendered characteristics that exist in the nursing staff's perception of the relatives.DiscussionThe study's limitations are primarily concerned with shortcomings associated with a research presence during the fieldwork. The discussion focuses on the dimensions of power structures observed in the nursing home routines and the staff's reasoning based on their gendered assumptions. We argue that it is important to develop mechanisms that provide opportunities for nursing staff in elderly care to reflect on these structures without downplaying the excellent care they provide. We stress the importance of further exploring these issues concerning relatives and their involvement in nursing homes to facilitate the transition from informal caregiver to ‘visitor’.

Conditions for relatives' involvement in nursing homes
- 2015

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The overall aim of this thesis was to describe and analyse how the involvement of relatives is conditioned in nursing homes from different critical perspectives. Gender perspectives, discourse analysis and intersectional theory are applied, based on social constructionist ontology. The thesis comprises three qualitative papers and data are based on ethnographically-focused fieldwork in three municipal nursing homes in the form of formal/informal interviews, participating observations and the analysis of documents.Based on gender perspectives, the routines and reasonings among nursing staff were studied and thematically analysed in relation to how these conditioned the involvement of relatives in the daily caring activities (I). In the second study (II), the nursing staff were interviewed in groups to describe, discursively analyse and identify the biopolitical meaning in the "involvement discourse" that was collectively constructed in the speech of the nursing staff concerning the involvement of relatives. In the last study (III), interviews with relatives were thematically analysed in the context of intersectional theory about their involvement in the nursing homes.The findings show that the conditions for relatives’ involvement were dynamic and constantly in re-negotiation, but also conservative and inflexible. This placed relatives in both privileged and unprivileged social positions in the nursing homes, which were relevant for their involvement. The relatives were considered to be "visitors", which conditioned the characteristics and levels of involvement in the care of the residents and was linked to gendered notions of the division of labor, both within the groups of relatives and between nursing staff and relatives (I). The involvement of relatives was conditioned by the biopolitics of an "involvement discourse" that prevailed in the nursing homes. This built upon family-oriented rhetorics and metaphors that upheld and legitimised notions about relatives. The relatives were considered to be members of the "old" family in relation to the "new" family represented by the nursing staff (II). The relatives described how they were positioned in a betweenship, squeezed between different competing social musts from the older family members, the nursing homes as institutions and the nursing staff (III).Inverting the prevailing picture of the involvement of relatives would make it possible to consider the nursing staff as pedagogical, professional and caring "visitors" in the nursing homes for the benefit of the residents and their relatives. This could be achieved through a constructive change management which emphasises the learning of nursing staff, their responsibility and the emotions of relatives, along with a focus on alternative notions of involvement, where relatives are included in the development of quality of care in Swedish nursing homes.

Tidskriftsartikel (refereegranskat)abstract
- This study seeks to understand, in the context of intersectional theory, the roles of family members in nursing home care. The unique social locus at which each person sits is the result of the intersection of gender, status, ethnicity and class; it is situational, shifting with the context of every encounter. A content analysis of 15 qualitative interviews with relatives of nursing home residents in Sweden was used to gain a perspective on the relationships between relatives and residents, relatives and the nursing home as an institution, and relatives and the nursing home staff. We sought to understand these relationships in terms of gendered notions of the family and the residents, which are handed down from generation to generation and thus condition who and how relatives should be involved in care, and the ways in which relationships change as care moves from home to nursing home. It requires knowledge and awareness that the nursing home culture is based on intersectional power structures in order for relatives to be involved in nursing home care in alternative and individual ways.

Tidskriftsartikel (refereegranskat)abstract
- Obesity is heritable and predisposes to many diseases. To understand the genetic basis of obesity better, here we conduct a genome-wide association study and Metabochip meta-analysis of body mass index (BMI), a measure commonly used to define obesity and assess adiposity, in up to 339,224 individuals. This analysis identifies 97 BMI-associated loci (P < 5 × 10(-8)), 56 of which are novel. Five loci demonstrate clear evidence of several independent association signals, and many loci have significant effects on other metabolic phenotypes. The 97 loci account for ∼2.7% of BMI variation, and genome-wide estimates suggest that common variation accounts for >20% of BMI variation. Pathway analyses provide strong support for a role of the central nervous system in obesity susceptibility and implicate new genes and pathways, including those related to synaptic function, glutamate signalling, insulin secretion/action, energy metabolism, lipid biology and adipogenesis.

Tidskriftsartikel (refereegranskat)abstract
- Measurement of thymidine kinase-1 (TK1) and deoxycytidine kinase (dCK) activity may be useful in cancer disease management. Therefore, a one-step homogeneous assay for real-time determination of TK1 and dCK was developed by combining enzyme complementation with fluorescent signal generation using primer extension and a quenched probe oligodeoxyribonucleotide system at 37 degrees C. Complementation, for producing dCTP and TIP from nucleoside substrates, was carried out by dTMP kinase and/or UMP/CMP kinase and nucleoside diphosphate kinase. dNTP was continuously incorporated into a fixed oligodeoxyribonucleotide primer, template, and probe system, and the fluorescent signal was generated by using the combined actions of primer extension and 5' exonuclease activity of Thermophilus aquaticus (Taq) DNA polymerase for specific relief of fluorescent quenching. Fluorescence was captured at 1-min intervals using a real-time polymerase chain reaction (PCR) instrument. A horizontal threshold line, crossing all sample relative fluorescent units (RFU) values at the level of the RFU of the blank sample at the end of the assay (i.e., 90 min), was drawn, obtaining RFU measurement data in minutes for each sample. Duplex proof of principle was demonstrated by the independent determination of different amounts of dCK and TK1 in combination. R-2 values of 0.90 were demonstrated with Prolifigen TK-REA U/L reference values obtained from pathological canine and human serum samples.
