Weathering rates in the Hietajärvi Integrated Monitoring catchment

Rates of Ca and Mg release by weathering were calculated for four soil profiles (Haplic Podzols) in a small forested catchment in eastern Finland (63°10´N, 30°43´E). Three of the profiles were developed on glacifluvial fine sand and one on till, and all derived from granodiorites. Soil weathering rates (mmolc m–2 a–1) were calculated using three methods: Zr depletion, Ca + Mg\temperature sum regression, and the PROFILE model. The first two methods give long-term average rates while the latter gives the current rate. According to the Zr depletion method, the weathering rate of Ca was 7–32 (mean = 19) and that of Mg, 3–16 (mean = 9). According to the regression method, the weathering rate of Ca was 14–19 (mean = 15) and that of Mg, 5–9 (mean = 7). The mean values using the PROFILE model were 10 (Ca) and 3 (Mg). Values were corrected for stone content. Catchment input-output budgets gave values of 18 (Ca) and 8 (Mg)

The effects of an alpha-2-adrenoceptor agonist, antagonist, and their combination on the blood insulin, glucose, and glucagon concentrations in insulin sensitive and dysregulated horses

Alpha-2-adrenoceptor agonists are sedatives that can cause fluctuations in serum insulin and blood glucose (BG) concentrations in horses. The objectives of this study were to investigate the effects of detomidine and vatinoxan on BG, insulin, and glucagon concentrations in horses with and without insulin dysregulation (ID). In a blinded cross-over design, eight horses with ID and eight horses without ID were assigned to each of four treatments: detomidine (0.02 mg/kg; DET), vatinoxan (0.2 mg/kg; VAT), detomidine + vatinoxan (DET + VAT), and saline control (SAL). Blood samples were taken at 0,1, 2, 4, 6, and 8 h. Change from baseline was used as the response in modelling, and the differences between treatments were evaluated with repeated measures analysis of covariance. P values 2021 The Authors.

Cancer Incidence and Mortality in the Oldest Old: a Nationwide Study in Finland

The world's population is aging rapidly. This study reports the burden of cancer in the oldest old (≥85 years) in Finland in 1953-2017 and estimates age-specific cancer rates in the old population (65-99 years) in 1988-2017. The Finnish Cancer Registry provided data on all cancer diagnoses, cancer deaths and other deaths in cancer patients in Finland in 1953-2017. Between 1953-1957 and 2013-2017, the proportion of incident cancers in those aged ≥85 years increased from 1.5% to 9.6% (597 to 15,360 new cases), and in 2013-2017, more new cancers were diagnosed at age ≥85 years than age <50 years. Cancer incidence and excess mortality attributable to cancer peaked at age 85-94 years and declined subsequently, whereas cancer-specific mortality continued to increase or plateaued. Due to demographic changes, the number of new cancers in the oldest old has increased substantially in Finland, and currently, nearly one in 10 cancers are diagnosed in this age group. The increasing cancer burden in the oldest old poses a major challenge for healthcare and needs to be addressed in designing clinical research and reporting of cancer registries. In old populations with competing risks of death, we propose excess cancer mortality as a measure of cancer-related mortality.Peer reviewe

Tying the Extended Family Knot: Grandparents’ Influence on Educational Achievement

In present-day western societies grandparents and grandchildren have longer years of shared lifetime than ever before. We investigate whether children with more grandparent resources have a higher probability of achieving the general secondary degree compared with children with fewer resources, or whether shared lifetime with grandparents increases the probability of achieving the general secondary degree. We use high-quality Finnish Census Panel data and apply sibling random and fixed-effects models that also control for all unobserved factors shared by siblings. Grandparents’ education and socioeconomic status have only a limited ability to explain a grandchild’s educational achievement. However, the sibling fixed-effects models reveal that every shared year between grandparents and grandchildren increases a grandchild’s likelihood of completing general secondary education by 1 percentage point, on average. The effect of shared lifetime is conditional on grandparental type, family resources, and the size of the extended family. Maternal grandmothers have a positive effect on grandchildren’s education in low-income families. Paternal grandmothers provide a link to the resources available through the extended family network, independent of their own resources. The same effects were not observed for grandfathers.</p

Optimal Doses of Specific Antipsychotics for Relapse Prevention in a Nationwide Cohort of Patients with Schizophrenia

Background and Hypothesis Optimal doses of most antipsychotics in the maintenance treatment of schizophrenia are unknown. We aimed to study the risk of severe relapse indicated by rehospitalization for different dose categories of 15 most frequently used antipsychotics in monotherapy in Finland. Study Methods We studied the risk of rehospitalization (Adjusted Hazard Ratio, aHR) associated with six antipsychotic monotherapy dose categories (as time-varying dose, measured in defined daily dose, DDDs/day) in a nationwide cohort of persons diagnosed with schizophrenia (n = 61 889), using within-individual analyses to eliminate selection bias. Study Results Among the 15 most widely used antipsychotics, 13 had a U- or J-shaped dose-response curve, showing the lowest risks of relapse for doses of 0.6-0.9 DDD/day, and especially at 1.4-Peer reviewe
