Many stroke patients and partners suffer from anxiety, depression, and low life satisfaction. Psychological factors such as coping style and self-efficacy can be protective factors within ...individuals. The close relationship between stroke patients and partners suggests that there may be interdependence in psychological functioning. The aim of this study was to examine intra- and interpersonal effects of coping style and self-efficacy on anxiety, depression, and life satisfaction in patient-partners couples. In this prospective cohort study, pro-active coping (UPCC), general self-efficacy (GSES), anxiety (HADS-A), depression (HADS-D), and life satisfaction (1-6 scale) were assessed in 215 couples at 2 and 12 months post-stroke. Effects within couples were assessed using structural equation modelling. Several intra- and interpersonal effects of coping style and self-efficacy at 2 months post-stroke were related to emotional health at 12 months post-stroke. Most effects were intrapersonal effects. The interpersonal effects were small but showed that pro-active coping by the patient was associated with lower anxiety of the partner. Higher self-efficacy of the partner was associated with lower depression scores and higher life satisfaction of the patient. This study underscores the importance of a dyadic approach to post-stroke functioning. It supports a family-based approach for treating post-stroke emotional problems.

The continued increase in the atmospheric concentration of carbon dioxide
due to anthropogenic emissions is predicted to lead to significant changes
in climate. About half of the current emissions ...are being absorbed
by the ocean and by land ecosystems, but this absorption is
sensitive to climate as well as to atmospheric carbon dioxide
concentrations, creating a feedback loop. General circulation
models have generally excluded the feedback between climate and the biosphere,
using static vegetation distributions and CO2 concentrations from
simple carbon-cycle models that do not include climate change.
Here we present results from a fully coupled, three-dimensional carbon-climate
model, indicating that carbon-cycle feedbacks could significantly accelerate
climate change over the twenty-first century. We find that under a 'business
as usual' scenario, the terrestrial biosphere acts as an overall carbon
sink until about 2050, but turns into a source thereafter. By 2100, the ocean
uptake rate of 5 Gt C yr-1 is balanced
by the terrestrial carbon source, and atmospheric CO2 concentrations
are 250 p.p.m.v. higher in our fully coupled simulation than in uncoupled
carbon models, resulting in a global-mean warming of 5.5 K,
as compared to 4 K without the carbon-cycle feedback.

Biodiversity loss is a major global challenge and minimizing extinction rates is the goal of several multilateral environmental agreements. Policy decisions require comprehensive, spatially explicit ...information on species' distributions and threats. We present an analysis of the conservation status of 14,669 European terrestrial, freshwater and marine species (ca. 10% of the continental fauna and flora), including all vertebrates and selected groups of invertebrates and plants. Our results reveal that 19% of European species are threatened with extinction, with higher extinction risks for plants (27%) and invertebrates (24%) compared to vertebrates (18%). These numbers exceed recent IPBES (Intergovernmental Platform on Biodiversity and Ecosystem Services) assumptions of extinction risk. Changes in agricultural practices and associated habitat loss, overharvesting, pollution and development are major threats to biodiversity. Maintaining and restoring sustainable land and water use practices is crucial to minimize future biodiversity declines.

The c.40_42delAGA variant in the phospholamban gene (PLN) has been associated with dilated and arrhythmogenic cardiomyopathy, with up to 70% of carriers experiencing a major cardiac event by age 70. ...However, there are carriers who remain asymptomatic at older ages. To understand the mechanisms behind this incomplete penetrance, we evaluated potential phenotypic and genetic modifiers in 74 PLN:c.40_42delAGA carriers identified in 36,339 participants of the Lifelines population cohort. Asymptomatic carriers (
N
= 48) showed shorter QRS duration (− 5.73 ms,
q
value = 0.001) compared to asymptomatic non-carriers, an effect we could replicate in two different independent cohorts. Furthermore, symptomatic carriers showed a higher correlation (
r
Pearson
= 0.17) between polygenic predisposition to higher QRS (PGS
QRS
) and QRS (
p
value = 1.98 × 10
–8
), suggesting that the effect of the genetic variation on cardiac rhythm might be increased in symptomatic carriers. Our results allow for improved clinical interpretation for asymptomatic carriers, while our approach could guide future studies on genetic diseases with incomplete penetrance.

Introduction
Non‐pharmacological treatments (NPTs) have the potential to improve meaningful outcomes for older people at risk of, or living with dementia, but research often lacks methodological ...rigor and continues to produce mixed results.
Methods
In the current position paper, experts in NPT research have specified treatment targets, aims, and ingredients using an umbrella framework, the Rehabilitation Treatment Specification System.
Results
Experts provided a snapshot and an authoritative summary of the evidence for different NPTs based on the best synthesis efforts, identified main gaps in knowledge and relevant barriers, and provided directions for future research. Experts in trial methodology provide best practice principles and recommendations for those working in this area, underscoring the importance of prespecified protocols.
Discussion
We conclude that the evidence strongly supports various NPTs in relation to their primary targets, and discuss opportunities and challenges associated with a unifying theoretical framework to guide future efforts in this area.
The first results of the UVic Earth System Model coupled to a land surface scheme and a dynamic global vegetation model are presented in this study. In the first part the present day climate ...simulation is discussed and compared to observations. We then compare a simulation of an ice age inception (forced with 116 ka BP orbital parameters and an atmospheric CO^sub 2^ concentration of 240 ppm) with a preindustrial run (present day orbital parameters, atmospheric CO^sub 2^ = 280 ppm). Emphasis is placed on the vegetation's response to the combined changes in solar radiation and atmospheric CO^sub 2^ level. A southward shift of the northern treeline as well as a global decrease in vegetation carbon is observed in the ice age inception run. In tropical regions, up to 88% of broadleaf trees are replaced by shrubs and C^sub 4^ grasses. These changes in vegetation cover have a remarkable effect on the global climate: land related feedbacks double the atmospheric cooling during the ice age inception as well as the reduction of the meridional overturning in the North Atlantic. The introduction of vegetation related feedbacks also increases the surface area with perennial snow significantly.PUBLICATION ABSTRACT
Summary These guidelines for use of narrowband (TL‐01) ultraviolet B have been prepared for dermatologists by the British Photodermatology Group on behalf of the British Association of ...Dermatologists. They present evidence‐based guidance for treatment of patients with a variety of dermatoses and photodermatoses, with identification of the strength of evidence available at the time of preparation of the guidelines, and a brief overview of background photobiology.
The public health threat posed by zoonotic Plasmodium knowlesi appears to be growing: it is increasingly reported across South East Asia, and is the leading cause of malaria in Malaysian Borneo. ...Plasmodium knowlesi threatens progress towards malaria elimination as aspects of its transmission, such as spillover from wildlife reservoirs and reliance on outdoor-biting vectors, may limit the effectiveness of conventional methods of malaria control. The development of new quantitative approaches that address the ecological complexity of P. knowlesi, particularly through a focus on its primary reservoir hosts, will be required to control it. Here, we review what is known about P. knowlesi transmission, identify key knowledge gaps in the context of current approaches to transmission modelling, and discuss the integration of these approaches with clinical parasitology and geostatistical analysis. We highlight the need to incorporate the influences of fine-scale spatial variation, rapid changes to the landscape, and reservoir population and transmission dynamics. The proposed integrated approach would address the unique challenges posed by malaria as a zoonosis, aid the identification of transmission hotspots, provide insight into the mechanistic links between incidence and land use change and support the design of appropriate interventions.
Summary
The bleeding patterns of severe von Willebrand's disease (VWD) adversely affect quality of life, and may be life threatening. There is a presumed role for prophylaxis with VWF‐containing ...concentrates, but data are scarce. The von Willebrand Disease Prophylaxis Network (VWD PN) was formed to investigate the role of prophylaxis in clinically severe VWD that is not responsive to other treatment(s).Using a retrospective design, the effect of prophylaxis was studied. Availability of records to document, or reliably assess, the type and frequency of bleeding episodes prior to, and after, the initiation of prophylaxis was required. Annualized bleeding rates were calculated for the period prior to prophylaxis, during prophylaxis and by primary bleeding indication defined as the site accounting for more than half of all bleeding symptoms. The Wilcoxon signed‐rank test of differences in the medians was used. Sixty‐one subjects from 20 centres in 10 countries were enrolled. Data for 59 were used in the analysis. The median age at onset of prophylaxis was 22.4 years. Type 3 VWD accounted for the largest number (N = 34, 57.6%). Differences in bleeding rates within individuals during compared with before prophylaxis were significant for the total group (P < 0.0001), and for those with primary bleeding indications of epistaxis (P = 0.0005), joint bleeding (P = 0.002) and GI bleeding (P = 0.001). The effect of prophylaxis was similar among those age < 18 years and those ≥18. One person developed an inhibitor during treatment. We conclude that prophylactic treatment of VWD is efficacious.
Partners of patients with stroke are at high risk for burden, anxiety and depressive symptoms. Previous studies have reported contradictory results and did not investigate these three courses ...simultaneously. In this study we comprehensively studied the courses and predictors of burden, anxiety and depressive symptoms in partners of patients with stroke during the first two years after stroke. They were analyzed as outcomes as well as predictors for each other.
Six general hospitals recruited 215 patients with stroke and their partners for a longitudinal cohort study. Mixed model analyses were performed for burden (CSI), anxiety (HADS-A) and depressive symptoms (HADS-D) as time-varying outcome variables, measured at four time points during two years after stroke.
Burden and depressive symptoms did not significantly change over time, whereas anxiety symptoms initially decreased followed by an increase. Higher burden was predicted by partners' younger age, higher education, more symptoms of anxiety and depression, and by patients' greater stroke severity, lower cognitive functioning and more symptoms of anxiety and depression. More anxiety symptoms were predicted by higher burden, more depressive symptoms, and lower self-efficacy of the partner. More depressive symptoms were predicted by older age, higher burden, more symptoms of anxiety, less proactive coping strategies of the partner, and more depressive symptoms of the patients.
Burden, anxiety and depressive symptoms are interrelated and become chronic in partners of patients with stroke. It is important to screen partners early after stroke to identify partners who are at risk for negative outcomes.
