Zebrafish optic nerve regeneration involves resident and retinal oligodendrocytes.

The visual system of teleost fish grows continuously, which is a useful model for studying regeneration of the central nervous system. Glial cells are key for this process, but their contribution is still not well defined. We followed oligodendrocytes in the visual system of adult zebrafish during regeneration of the optic nerve at 6, 24, and 72 hours post-lesion and at 7 and 14 days post-lesion via the sox10:tagRFP transgenic line and confocal microscopy.

Retrospective analysis of 80 patients diagnosed with reversible cerebral vasoconstriction syndrome in the Helsinki Metropolitan Area.

Background And Purpose: Up to 80% of patients diagnosed with reversible cerebral vasoconstriction syndrome (RCVS) experience complications such as ischaemic stroke, intracerebral or subarachnoid haemorrhage or posterior reversible encephalopathy syndrome. The aim was to evaluate the incidence of complications in patients diagnosed with RCVS in our clinic.

Patients And Methods: All adult patients (age >16 years) diagnosed with RCVS at the Helsinki University Central Hospital during the period between 1 January 2016 and 31 December 2022 were retrospectively identified.

Systematic Study of Hard-Wall Confinement-Induced Effects on Atomic Electronic Structure.

We point out that although a litany of studies have been published on atoms in hard-wall confinement, they have either not been systematic, having only looked at select atoms and/or select electron configurations, or they have not used robust numerical methods. To remedy the situation, we perform in this work a methodical study of atoms in hard-wall confinement with the HelFEM program, which employs the finite element method that trivially implements the hard-wall potential, guarantees variational results, and allows for easily finding the numerically exact solution. Our fully numerical calculations are based on nonrelativistic density functional theory and spherically averaged densities.

Vulvar inspection at the time of cervical cancer screening: European Society of Gynaecological Oncology (ESGO), International Society for the Study of Vulvovaginal Disease (ISSVD), European College for the Study of Vulval Disease (ECSVD), and European Federation for Colposcopy (EFC) consensus statements.

Background: Vulvar squamous cell carcinoma incidence is increasing, especially among women under 60, largely attributed to human papillomavirus infections. Precursor pre-invasive vulvar lesions are frequently underdiagnosed. Routine vulvar inspection during cervical cancer screening could offer an opportunity for the detection of these lesions.

Clinicopathologic stratification demonstrates survival differences between endometrial carcinomas with mismatch repair deficiency and no specific molecular profile: a cohort study.

Objective: Endometrial carcinomas with mismatch repair deficiency (MMRd) and no specific molecular profile (NSMP) are considered to have intermediate prognoses. However, potential prognostic differences between these molecular subgroups remain unclear due to the lack of standardized control for clinicopathologic factors. This study aims to evaluate outcomes of MMRd and NSMP endometrial carcinomas across guideline-based clinicopathologic risk groups.

Educational Disparities in Age-related Hearing Loss and Hearing Aid Use across Age, Gender, and European Region.

Objectives: Affecting one in five adults in Europe, hearing loss (HL) is linked to adverse health outcomes, including dementia. We aim to investigate educational inequalities in hearing health in Europe and how these inequalities change with age, gender, and region.

Methods: Utilizing 2004-2020 data from the Harmonised Survey of Health, Ageing, and Retirement in Europe (SHARE), a representative sample of Europeans aged 50 and above, we analyse: 1) age-standardized prevalence of HL and hearing aid (HA) use among eligible individuals; 2) educational inequalities therein using the Relative Index of Inequality (RII) across age, gender, and European regions.

A deep intronic variant associated with X-linked hypophosphatemia in a Finnish family.

Hypophosphatemic rickets is a rare bone disease characterized by short stature, bone deformities, impaired bone mineralization, and dental problems. Most commonly, hypophosphatemic rickets is caused by pathogenic variants in the X-chromosomal gene, but autosomal dominant and recessive forms also exist. We investigated a Finnish family in which the son (index, 29 yr) and mother (56 yr) had hypophosphatemia since childhood.

MEPFeatX-automated feature extraction of motor-evoked potentials in transcranial magnetic stimulation.

Motor evoked potentials (MEPs) are an important measure in transcranial magnetic stimulation (TMS) when assessing neuronal excitability in clinical diagnostics related to motor function, as well as in neuroscience research. However, manual feature extraction from large datasets can be time-consuming and prone to human error, and valuable features, such as MEP polyphasia and duration, are often neglected. Several packages have been developed to simplify the process; however, they are often tailored to specific studies or are not accessible.

Assessing response to stressful emotions: a controlled crossover study using pupillometry.

Background: Fear and horror induce autonomic protective responses, acting as "survival intelligence." Pupillometry is an innovative method that captures real-time autonomic nervous system reactions to stress.

Objective: To evaluate the feasibility of pupillometry to assess the acute response to a passive real-life stressor-viewing a truthful war scene.

Photobioreactor design utilizing procedural three-dimensional modelling and ray tracing.

The design of photobioreactors for microalgae cultivation aims to achieve an architecture that allows the most efficient photosynthetic growth. The availability of light at wavelengths that are important for photosynthesis is therefore particularly crucial for reactor design. While testing different reactor types in practice is expensive, simulations could effectively limit the range of material and reactor design options.

The promise of community-driven preprints in ecology and evolution.

Publishing preprints is quickly becoming commonplace in ecology and evolutionary biology. Preprints can facilitate the rapid sharing of scientific knowledge establishing precedence and enabling feedback from the research community before peer review. Yet, significant barriers to preprint use exist, including language barriers, a lack of understanding about the benefits of preprints and a lack of diversity in the types of research outputs accepted (e.

Long COVID and its risk factors in migrants: a nationwide register study from Sweden.

Background: Many studies have found more severe COVID-19 outcomes in migrants and ethnic minorities throughout the COVID-19 pandemic, while recent evidence also suggests higher risk of longer-term consequences. We studied the risk of a long COVID diagnosis among adult residents in Sweden, dependent on country of birth and accounting for known risk factors for long COVID.

Methods: We used linked Swedish administrative registers between March 1, 2020 and April 1, 2023, to estimate the risk of a long COVID diagnosis in the adult population that had a confirmed COVID-19 infection.

Neonatal outcomes in twin pregnancies in Finland from 2008 to 2023.

Unlabelled: Twin pregnancies are associated with higher risks of adverse maternal and neonatal outcomes compared to singleton pregnancies. This retrospective nationwide cohort study analyzed trends in twin pregnancy outcomes in Finland from 2008 to 2023 using data from the Finnish Medical Birth Register. Outcomes assessed included perinatal mortality, stillbirths, neonatal mortality, neonatal intensive care unit (NICU) admissions, and hospitalization rates at one week of age.

Associations between common genetic variants and income provide insights about the socio-economic health gradient.

We conducted a genome-wide association study on income among individuals of European descent (N = 668,288) to investigate the relationship between socio-economic status and health disparities. We identified 162 genomic loci associated with a common genetic factor underlying various income measures, all with small effect sizes (the Income Factor). Our polygenic index captures 1-5% of income variance, with only one fourth due to direct genetic effects.

fMRI data acquisition and analysis for task-free, anesthetized rats.

Templates for the acquisition of large datasets such as the Human Connectome Project guide the neuroimaging community to reproducible data acquisition and scientific rigor. By contrast, small animal neuroimaging often relies on laboratory-specific protocols, which limit cross-study comparisons. The establishment of broadly validated protocols may facilitate the acquisition of large datasets, which are essential for uncovering potentially small effects often seen in functional MRI (fMRI) studies.

Betula pendula Roth. survival and growth in treeline is affected by genotype and environment.

Alpine and Arctic treelines are assumed to be shifting toward higher latitudes and altitudes as a consequence of climate warming. Here, we compared the survival and growth of 1264 silver birch (Betula pendula Roth.) trees representing nine half-sib families.

Surveillance of primary sclerosing cholangitis - a comparison of scheduled or on-demand ERCP with annual MRI surveillance: a multicenter study.

Primary sclerosing cholangitis (PSC) is associated with a high risk of hepatobiliary malignancy, especially cholangiocarcinoma (CCA). There are no good tumor markers to screen for CCA, and current recommendations for PSC monitoring are mainly based on expert opinions. The optimal strategy to assess disease progression and screen for CCA - the main cause of death of PSC patients - remains unclear.

Illnesses and Diseases Constitute a Quarter of Medical Conditions in an Under-21 National Football Team.

Context: There is a minimal number of studies of under-21-year-old national football teams, and the literature is injury centric. Particularly, current knowledge is deficient regarding noninjurious medical conditions, such as illnesses and diseases.

Design: The objectives of this study were to analyze the descriptive characteristics of injuries and illnesses or diseases encountered in an under-21 football team during 2 European championship qualification tournaments.

Epidemiology and genetic characterization of myxoma virus from the first outbreak in Finland.

Myxomatosis, caused by myxoma virus (MYXV), is a fatal disease of the European rabbit (Oryctolagus cuniculus). It has a worldwide distribution and has become an endemic disease throughout Europe since its introduction into the rabbit population in 1950. This study describes the first outbreak caused by MYXV in Finland in summer 2020.

Earlier pregnancies in nulliparous women with current father and lower risks for preeclampsia and low-birth weight newborns.

New paternity has been related to placenta-associated complications in pregnancy. We evaluated whether a lack of earlier pregnancies or deliveries with a current father are associated with the pregnancy, prenatal, and early neonatal outcomes after controlling for the most common maternal confounders in prospective birth cohort study. An online questionnaire was used to survey 4459 pregnant women from the Kuopio Birth Cohort in their third trimester.
