- Wetland methane (CH4) emissions ([Formula: see text]) are important in global carbon budgets and climate change assessments. Currently, [Formula: see text] projections rely on prescribed static temperature sensitivity that varies among biogeochemical models. Meta-analyses have proposed a consistent [Formula: see text] temperature dependence across spatial scales for use in models; however, site-level studies demonstrate that [Formula: see text] are often controlled by factors beyond temperature. Here, we evaluate the relationship between [Formula: see text] and temperature using observations from the FLUXNET-CH4 database. Measurements collected across the globe show substantial seasonal hysteresis between [Formula: see text] and temperature, suggesting larger [Formula: see text] sensitivity to temperature later in the frost-free season (about 77% of site-years). Results derived from a machine-learning model and several regression models highlight the importance of representing the large spatial and temporal variability within site-years and ecosystem types. Mechanistic advancements in biogeochemical model parameterization and detailed measurements in factors modulating CH4 production are thus needed to improve global CH4 budget assessments.

- Background: The German Guideline on Screening, Diagnosis and Treatment of Alcohol Use Disorders aims to increase the uptake of evidence-based interventions for the early identification, diagnosis, prevention and treatment of alcohol-related disorders in relevant healthcare settings. To date, dissemination has not been accompanied by a guideline implementation strategy. The aim of this study is to develop tailored guideline implementation strategies and to field-test these in relevant medical and psycho-social settings in the city of Bremen, Germany. Methods: The study will conduct an impact and needs assessment of healthcare provision for alcohol use orders in Bremen, drawing on a range of secondary and primary data to: evaluate existing healthcare services; model the potential impact of improved care on public health outcomes; and identify potential barriers and facilitators to implementing evidence-based guidelines. Community advisory boards will be established for the selection of single-component or multi-faceted guideline implementation strategies. The tailoring approach considers guideline, provider and organizational factors shaping implementation. In field tests quality outcome indicators of the delivery of evidence-based interventions will be evaluated accompanied by a process evaluation to examine patient, provider and organizational factors. Outlook: This project will support the translation of guideline recommendations for the identification, prevention and treatment of AUD in routine practice and therefore contributes to the reduction of alcohol-related burden in Germany. The project is running since October 2017 and will provide its main outcomes by end of 2020. Project results will be published in scientific journals and presented at national and international conferences.

- Distressing intrusive memories of a traumatic event are one of the hallmark symptoms of posttraumatic stress disorder. Thus, it is crucial to identify early interventions that prevent the occurrence of intrusive memories. Both, sleep and sleep deprivation have been discussed as such interventions, yet previous studies yielded contradicting effects. Our systematic review aims at evaluating existing evidence by means of traditional and individual participant data (IPD) meta-analyses to overcome power issues of sleep research. Until May 16th, 2022, six databases were searched for experimental analog studies examining the effect of post-trauma sleep versus wakefulness on intrusive memories. Nine studies were included in our traditional meta-analysis (8 in the IPD meta-analysis). Our analysis provided evidence for a small effect favoring sleep over wakefulness, log-ROM = 0.25, p < .001, suggesting that sleep is associated with a lower number of intrusions but unrelated to the occurrence of any versus no intrusions. We found no evidence for an effect of sleep on intrusion distress. Heterogeneity was low and certainty of evidence for our primary analysis was moderate. Our findings suggest that post-trauma sleep has the potential to be protective by reducing intrusion frequency. More research is needed to determine the impact following real-world trauma and the potential clinical significance.
