Designing Depression Screening Chatbots.

Advances in voice recognition, natural language processing, and artificial intelligence have led to the increasing availability and use of conversational agents (chatbots) in different settings. Chatbots are systems that mimic human dialogue interaction through text or voice. This paper describes a series of design considerations for integrating chatbots interfaces with health services. The present paper is part of ongoing work that explores the overall implementation of chatbots in the healthcare context. The findings have been created using a research through design process, combining (1) literature survey of existing body of knowledge on designing chatbots, (2) analysis on state-of-the-practice in using chatbots as service interfaces, and (3) generative process of designing a chatbot interface for depression screening. In this paper we describe considerations that would be useful for the design of a chatbot for a healthcare context.

Exploring users' willingness to share their health and personal data under the prism of the new GDPR: implications in healthcare.

At the same time healthcare undergoes a digital transformation, the implementation of the new General Data Protection Regulation (GDPR) introduces changes to internet users. Understanding users' data-sharing attitudes for four type of personal data in regards to the new GDPR can facilitate stakeholders and policy-makers in healthcare to make sense of the current landscape. Authors analyzed the results of a questionnaire survey to explore the willingness of 8.004 people across four European countries to share four types of data: health; perceived values or beliefs; consumption habits and purchases; and wealth. Our results suggest that participants are more willing to share health data and data about beliefs and values than wealth information and that GDPR has impacted the data-sharing behavior of the participants.

Personal Health Data: Access and Perceived Value in Denmark.

This study explores how accessible and valuable Personal Health Data are in Denmark. This paper uses a qualitative inquiry which was adopted to provide information about (1) the accessibility of data available, (2) and the perceived value of data by recruiting 8 healthy Danish individuals who were instructed to access their personal health data, and were then prompted to discuss how accessible and valuable they perceived their personal health data to be. In total, participants accessed 31 datasets and wearable sensor data through 23 web applications and 8 mobile applications. They reported on search and access challenges in interviews and through journaling. Our results suggest that participants were satisfied with the access they had to their personal health data, however the participants expressed disappointment in ways the data was presented for them by the services and platforms. Thus, we concluded that the perceived value of personal data were found to be dependent on the usability and personalization features of the services, rather than on the data itself.

Aleutian mink disease virus in free-ranging mustelids in Finland - a cross-sectional epidemiological and phylogenetic study.

Aleutian mink disease virus (AMDV) can cause severe immune-complex-mediated disease in American mink. AMDV has also been detected in several other mustelid species with potential negative impact on their health and population. A molecular and cross-sectional epidemiological study was conducted to obtain data on the prevalence, distribution, transmission and diversity of AMDV strains in Finnish free-ranging mustelids and risk factors associated with infection. The presence of anti-AMDV antibodies and/or AMDV DNA was tested from 308 samples representing eight mustelid species and 17 administrative regions. Positive samples were detected across Finland, and in 54 % (31/57) of feral American mink, 27 % (7/26) of European badgers and 7 % (1/14) of European polecats. Samples from Eurasian otters, European pine martens, least weasels, stoat and wolverine were negative. Major risk factors for infection were the species American mink with 335 and badger with 74 times higher odds than other species, and the years 2006-2009 with five times higher odds than the years 2010-2014. No clustering according to species, geographical origin or year was evident in phylogeny, except for four divergent sequences from Estonian badgers that formed a separate phylogroup distinct from other AMDV strains. This study showed that AMDV was prevalent in certain species of Finnish free-ranging mustelids and widely distributed across Finland. Furthermore, the free-ranging mustelids carried both strains similar to those found in farmed mink, but also distinct strains that may represent novel amdoparvoviruses.

Identification and intraspecific genetic diversity of Sarcocystis rileyi from ducks, Anas spp., in Lithuania and Finland.

Macroscopic Sarcocystis cysts were detected in the muscles of 28 Mallards ( Anas platyrhynchos ), 1 Eurasian Wigeon ( Anas penelope ), and 1 Common Teal ( Anas crecca ) hunted in Lithuania and Finland. According to the sequences of the 18S rRNA gene, 28S rRNA gene, and ITS-1 region, the macrocysts examined from all 30 ducks belonged to Sarcocystis rileyi. This parasite was found in the Eurasian Wigeon and the Common Teal for the first time. All S. rileyi isolates examined were identical to each other and differed from 2 S. rileyi isolates previously reported from 2 Mallards from the United States only by 1 nucleotide substitution within the ITS-1 region.

Balancing selection and heterozygote advantage in major histocompatibility complex loci of the bottlenecked Finnish wolf population.

Maintaining effective immune response is an essential factor in the survival of small populations. One of the most important immune gene regions is the highly polymorphic major histocompatibility complex (MHC). We investigated how a population bottleneck and recovery have influenced the diversity and selection in three MHC class II loci, DLA-DRB1, DLA-DQA1 and DLA-DQB1, in the Finnish wolf population. We studied the larger Russian Karelian wolf population for comparison and used 17 microsatellite markers as reference loci. The Finnish and Karelian wolf populations did not differ substantially in their MHC diversities (GST″ = 0.047, P = 0.377), but differed in neutral microsatellite diversities (GST″ = 0.148, P = 0.008). MHC allele frequency distributions in the Finnish population were more even than expected under neutrality, implying balancing selection. In addition, an excess of nonsynonymous compared to synonymous polymorphisms indicated historical balancing selection. We also studied association between helminth (Trichinella spp. and Echinococcus canadensis) prevalence and MHC diversity at allele and SNP level. MHC-heterozygous wolves were less often infected by Trichinella spp. and carriers of specific MHC alleles, SNP haplotypes and SNP alleles had less helminth infections. The associated SNP haplotypes and alleles were shared by different MHC alleles, which emphasizes the necessity of single-nucleotide-level association studies also in MHC. Here, we show that strong balancing selection has had similar effect on MHC diversities in the Finnish and Russian Karelian wolf populations despite significant genetic differentiation at neutral markers and small population size in the Finnish population.

Molecular identification of Taenia spp. in the Eurasian lynx (Lynx lynx) from Finland.

Cestodes of the genus Taenia are parasites of mammals, with mainly carnivores as definitive and herbivores as intermediate hosts. Various medium-sized cats, Lynx spp., are involved in the life cycles of several species of Taenia. The aim of the present study was to identify Taenia tapeworms in the Eurasian lynx (Lynx lynx) from Finland. In total, 135 tapeworms from 72 lynx were subjected to molecular identification based on sequences of 2 mtDNA regions, the cytochrome c oxidase subunit 1 and the NADH dehydrogenase subunit 1 genes. Available morphological characters of the rostellar hooks and strobila were compared. Two species of Taenia were found: T. laticollis (127 samples) and an unknown Taenia sp. (5 samples). The latter could not be identified to species based on mtDNA, and the rostellar hooks were short relative to those described among other Taenia spp. recorded in felids from the Holarctic region. In the phylogenetic analyses of mtDNA sequences, T. laticollis was placed as a sister species of T. macrocystis, and the unknown Taenia sp. was closely related to T. hydatigena and T. regis. Our analyses suggest that these distinct taeniid tapeworms represent a putative new species of Taenia. The only currently recognized definitive host is L. lynx and the intermediate host is unknown.
