The human brain is particularly vulnerable to heat stress; this manifests as impaired cognition, orthostatic tolerance, work capacity and eventually, brain death. The brain's limitation in the heat is often ascribed to inadequate cerebral blood flow (CBF), but elevated intracranial pressure is commonly observed in mammalian models of heat stroke and can on its own cause functional impairment. The CBF response to incremental heat strain was dependent on the mode of heating, decreasing by 30% when exposed passively to hot, humid air (sauna), while remaining unchanged or increasing with passive hot-water immersion (spa) and exercising in a hot environment. Non-invasive intracranial pressure estimates (nICP) were increased universally by 18% at volitional thermal tolerance across all modes of heat stress, and therefore may play a contributing role in eliciting thermal tolerance. The sauna, more so than the spa or exercise, poses a greater challenge to the brain under mild to severe heating due to lower blood fl nICP increased universally by 18% with all modes of heating (P less then 0.001). The maximum Tc was achieved with passive heating, and preventing hypocapnia during exercise did not improve exercise or thermal tolerance (P ≥ 0.146). Therefore, the regulation of CBF is dramatically different depending on the mode and dose of heating, whereas nICP responses are not. The sauna, more so than the spa or exercise, poses a greater challenge to the brain under equivalent heat strain.

Psoriasis is a chronic, inflammatory skin disease that affects 0.71% of children. Skin diseases can have a significant impact on quality of life not only for the children affected by psoriasis, but also for their parents and carers. This study aimed to achieve more insight into the quality of life (QOL) of family of paediatric patients with psoriasis, and to investigate whether disease severity scores correlate with Family Dermatology Life Quality Index (FDLQI) scores. In addition, we also observed the treatments used to treat paediatric psoriasis in daily clinical practice.

Patients with paediatric psoriasis aged 16 and under who visited our outpatient department were included. Baseline Psoriasis Area and Severity Index (PASI) and FDLQI were measured and analysed.

Of 157 patients were included in the study. EKI-785 molecular weight Median PASI was 4.2 (IQR 2.6-6.9), and the median FDLQI was 12 (IQR 7-17). The correlation coefficient between PASI and FDLQI was 0.44 (P<0.001). Burden of care was the highest scoring item on the FDLQI, followed by emotional impact. 146 patients were treated with topical therapy with a mean improvement in PASI of 3.92. 19 patients underwent phototherapy, and 19 underwent systemic therapy.

In this largest study to date studying the impact of PASI on FDLQI, disease severity was found to be strongly associated with adverse quality of life of family members of paediatric psoriasis patients.

Tackling this question is crucial to better understanding terrestrial responses to climate change as fine-root traits drive many ecosystem processes. We carried out a detailed synthesis of fine-root trait responses to experimental warming by performing a meta-analysis of 964 paired observations from 177 publications. Warming increased fine-root biomass, production, respiration and nitrogen concentration as well as decreased root carbon nitrogen ratio and nonstructural carbohydrates. Warming effects on fine-root biomass decreased with greater warming magnitude, especially in short-term experiments. Furthermore, the positive effect of warming on fine-root biomass was strongest in deeper soil horizons and in colder and drier regions. Total fine-root length, morphology, mortality, life span and turnover were unresponsive to warming. Our results highlight the significant changes in fine-root traits in response to warming as well as the importance of warming magnitude and duration in understanding fine-root responses. These changes have strong implications for global soil carbon stocks in a warmer world associated with increased root-derived carbon inputs into deeper soil horizons and increases in fine-root respiration.The interplay between top-down and bottom-up processes determines ecosystem productivity. Yet, the factors that mediate the balance between these opposing forces remain poorly understood. Furthering this challenge, complex and often cryptic factors like ecosystem engineering and trait-mediated interactions may play major roles in mediating the outcomes of top-down and bottom-up interactions. In semiarid grasslands of northeastern China, we conducted a large-scale, three-year experiment to evaluate how soil engineering by ants and plasticity in plants independently and jointly influenced the top-down effects of grazing by a ubiquitous herbivore (cattle) on aboveground standing biomass of the dominant perennial grass, Leymus chinensis. Herbivory had strong top-down effects, reducing L. chinensis AB by 25% relative to baseline levels without cattle or ants. In contrast, soil engineering by ants facilitated weak bottom-up effects in the absence of herbivory. However, in the presence of herbivory, soil engineeringerhaps ubiquitous processes may help to explain the long-debated phenomenon of plant compensatory responses to large grazers.

To explore the financial impact of cancer in young adults (YAs) compared to matched non-cancer peers.

Five hundred seventy-five YAs from the Young Adults with Cancer in their Prime (YACPRIME) studyreported on out-of-pocket cancer costs and missed work. YA cancer survivors were compared to matched peers without cancer on key financial indices based on current age (< 35 vs. 35 + years) and time since diagnosis (< 5 vs. 5 + years). Descriptive statistics, Chi-square tests, and prevalence ratios (PR) were used to compare groups on financial variables.

Almost 60% of YA survivors spent at least $100/month on cancer-related expenses, and 49% missed at least one year of work. YA survivors were more likely to have outstanding credit card ((< 35 (PR = 1.37, p = 0.001); 35 + (PR = 1.33, p = 0.001)) and line of credit (< 35 (PR = 1.42, p = 0.008); 35 + (PR = 1.27, p = 0.016)) balances. Home ownership was higher among non-cancer peers ((< 35 PR = 1.42, p < 0.001); 35 + (PR = 1.69, p < 0.001); < 5 years (PR = 1.
