Seasonal soil moisture and drought occurrence in Europe in CMIP5 projections for the 21st century

Kimmo Ruosteenoja, Tiina Markkanen, Ari Venäläinen, Petri Räisänen, Heli Peltola
2017 Climate Dynamics  
Projections for near-surface soil moisture content in Europe for the 21st century were derived from 7 simulations performed with 26 CMIP5 global climate models (GCMs). Two Representative Concentration 8 Pathways, RCP4.5 and RCP8.5, were considered. Unlike in previous research in general, projections were 9 calculated separately for all four calendar seasons. To make the moisture contents simulated by the various 10 GCMs commensurate, the moisture data were normalized by the corresponding local

A majority of the GCMs proved to perform satisfactorily in simulating the 12 geographical distribution of recent soil moisture in the warm season, the spatial correlation with an satellite-13 derived estimate varying between 0.4-0.8. 14 In southern Europe, long-term mean soil moisture is projected to decline substantially in all seasons. In 15 summer and autumn, pronounced soil drying also afflicts western and central Europe. In northern Europe, 16 drying mainly occurs in spring, in correspondence with an earlier melt of snow and soil frost. The spatial 17 pattern of drying is qualitatively similar for both RCP scenarios, but weaker in magnitude under RCP4.5. 18 In general, those GCMs that simulate the largest decreases in precipitation and increases in temperature and 19 solar radiation tend to produce the most severe soil drying. 20 Concurrently with the reduction of time-mean soil moisture, episodes with an anomalously low soil 21 moisture, occurring once in 10 years in the recent past simulations, become far more common. In southern 22 Europe by the late 21st century under RCP8.5, such events would be experienced about every second year. 23

1998 Journal of Infectious Diseases  
The viral etiology of measles-or rubella-like illnesses after MMR (measles, mumps, and rubella) vaccination was studied prospectively in 993 acutely ill Finnish children with fever and rash in 1983-1995. Their sera were tested for adeno-, entero-, and parvovirus B19 antibodies. Sera of 300 children !4 years old were also tested for human herpesvirus 6 (HHV-6) antibodies. Measles and rubella had been excluded by previous antibody testing. Serologic diagnosis of adeno-, entero-, or parvovirus

A viral etiology was verified in 368 cases, most commonly parvovirus (20%), followed by enterovirus (9%) and adenovirus (4%). Among young children, HHV-6 infection was found in 37 (12%). Thirty-eight children (4%) had double infections. This study confirms that measles-or rubella-like illnesses in MMR-vaccinated children are often caused by other viruses. Each suspected vaccine failure requires laboratory confirmation to maintain reliable surveillance and control and to establish the specific etiology of the disease.

Antiepileptic drugs (AED) with histone deacetylase (HDAC) inhibitor properties decrease prostate cancer (PCa) cell proliferation in vitro. A population-based cohort of 78 615 men was used to evaluate the risk of prostate cancer among users of AEDs. Study population was linked to the Finnish national prescription database to obtain information on individual medication reimbursements in 1996-2015.

The analysis was adjusted for age, screening trial arm and other drugs in use, including statins, antidiabetic drugs, antihypertensive drugs, aspirin and NSAIDs. Compared to the non-users of antiepileptic drugs, overall PCa risk was decreased among antiepileptic drug users (HR 0.86, 95% CI 0.76-0.96). A similar PCa risk decrease was observed among users of HDACi AEDs (HR 0.87, 95% CI 0.76 - 1.01), but no risk difference was found when comparing HDACi AED users to users of other AEDs (HR 0.98, 95% CI 0.76 - 1.27). Our study showed a decrease in overall PCa risk among men using AEDs compared to non-users. The risk associations were similar for HDAC inhibitors as for antiepileptic drugs in general.

2015 Critical Care  
Deep sedation is associated with adverse patient outcomes. We recently described a novel sedation-monitoring technology, the Responsiveness Index (RI), which quantifies patient arousal using processed frontal facial EMG data. We explored the potential effectiveness and safety of continuous RI monitoring during early intensive care unit (ICU) care as a nurse decision-support tool. Methods: In a parallel-group controlled single centre proof of concept trial, patients requiring mechanical

Control group patients received hourly clinical sedation assessment and daily sedation holds; the RI monitor was connected but data were concealed from clinical staff. The intervention group received control group care, but RI monitoring was visible and nurses were asked to adjust sedation to maintain patients with an RI>20 whenever possible. Traffic-light colour coding (RI<20, Red; 20-40, Amber; >40, Green) simplified decision-making. The intervention lasted up to 48 hours. Sixteen nurses were interviewed to explore their views of the novel technology. Results: We analysed 74 patients treated per protocol (36 intervention; 38 control). The proportion of patients with RI<20 was identical at the start of monitoring (54 % both groups). Overall, the proportion of time with RI<20 trended to lower values for the intervention group (median 16 % (1-3rd quartile 8-30 %) versus 33 % (10-54 %); P = 0.08); sedation and analgesic use was similar. A post hoc analysis restricted to patients with RI<20 when monitoring started, found intervention patients spent less time with low RI value (16 % (11-45 %) versus 51 % (33-72 %); P = 0.02), cumulative propofol use trended to lower values (median 1090 mg versus 2390 mg; P = 0.14), and cumulative alfentanil use was lower (21.2 mg versus 32.3 mg; P = 0.01). RASS scores were similar for both groups. Sedation related adverse event rates were similar (7/36 versus 5/38). Similar proportions of patients had sedation holds (83 % versus 87 %) and were extubated (47 % versus 44 %) during the intervention period. Nurses valued the objective visible data trends and simple colour prompts, and found RI monitoring a useful adjunct to existing practice. Conclusions: RI monitoring was safe and acceptable. Data suggested potential to modify sedation decision-making. Larger trials are justified to explore effects on patient-centred outcomes. Trial registration: NCT01361230 (registered

Abstract. The formation of ice particles in Earth's atmosphere strongly influences the dynamics and optical properties of clouds and their impacts on the climate system. Ice formation in clouds is often triggered heterogeneously by ice-nucleating particles (INPs) that represent a very low number of particles in the atmosphere. To date, many sources of INPs, such as mineral and soil dust, have been investigated and identified in the low and mid latitudes. Although less is known about the sources

In this study, we investigate the INP emission potential from high-latitude boreal forests in the mixed-phase cloud regime. We introduce the HyICE-2018 measurement campaign conducted in the boreal forest of Hyytiälä, Finland, between February and June 2018. The campaign utilized the infrastructure of the Station for Measuring Ecosystem-Atmosphere Relations (SMEAR) II, with additional INP instruments, including the Portable Ice Nucleation Chamber I and II (PINC and PINCii), the SPectrometer for Ice Nuclei (SPIN), the Portable Ice Nucleation Experiment (PINE), the Ice Nucleation SpEctrometer of the Karlsruhe Institute of Technology (INSEKT) and the Microlitre Nucleation by Immersed Particle Instrument (µL-NIPI), used to quantify the INP concentrations and sources in the boreal environment. In this contribution, we describe the measurement infrastructure and operating procedures during HyICE-2018, and we report results from specific time periods where INP instruments were run in parallel for inter-comparison purposes. Our results show that the suite of instruments deployed during HyICE-2018 reports consistent results and therefore lays the foundation for forthcoming results to be considered holistically. In addition, we compare measured INP concentrations to INP parameterizations, and we observe good agreement with the Tobo et al. (2013) parameterization developed from measurements conducted in a ponderosa pine forest ecosystem in Colorado, USA.
