Genome-wide Analyses Identify KIF5A as a Novel ALS Gene

To identify novel genes associated with ALS, we undertook two lines of investigation. We carried out a genome-wide association study comparing 20,806 ALS cases and 59,804 controls. Independently, we performed a rare variant burden analysis comparing 1,138 index familial ALS cases and 19,494 controls. Through both approaches, we identified kinesin family member 5A (KIF5A) as a novel gene associated with ALS. Interestingly, mutations predominantly in the N-terminal motor domain of KIF5A are causative for two neurodegenerative diseases: hereditary spastic paraplegia (SPG10) and Charcot-Marie-Tooth type 2 (CMT2). In contrast, ALS-associated mutations are primarily located at the C-terminal cargo-binding tail domain and patients harboring loss-of-function mutations displayed an extended survival relative to typical ALS cases. Taken together, these results broaden the phenotype spectrum resulting from mutations in KIF5A and strengthen the role of cytoskeletal defects in the pathogenesis of ALS.Peer reviewe

Identifying and Predicting the Goals and Concerns Prioritized by Individuals with Inflammatory Bowel Disease

Background and Aims: In order to provide high-quality care, providers need to understand their patients’ goals and concerns. This study aims to identify and predict the goals and concerns prioritised by patients with inflammatory bowel disease [IBD] in the outpatient setting. Methods: Mixed-methods analysis was performed to identify the types, frequencies, and predictors of IBD patients’ goals and concerns using 4873 surveys collected over 2016–2019 at 25 gastroenterology clinics across the USA participating in the Crohn’s & Colitis Foundation’s IBD Qorus Learning Health System. Results: Patients with IBD most often prioritised goals and concerns related to symptoms/disease activity [50%] and clinical course/management [20%], whereas psychosocial/quality of life [12%] and medication [6%] concerns were less frequent. Females (odds ratio [OR] 22.1, 95% confidence interval [CI] 5.3–91.5) and patients in clinical remission [OR 2.2, 95% CI 1.2–4.1] were more likely to prioritise family planning. Patients >60 years old [OR 3.1, 95% CI 1.5–6.5] and patients with active disease [OR 3.2, 95% CI 1.4–7.6] were more often concerned about travelling. Smokers were more often concerned about nutrition [OR 4.2, 95% CI 1.9–9.2]. Surgery was more often a concern of patients with perianal Crohn’s disease [OR 2.1, 95% CI 1.2–3.5], active disease [OR 1.9, 95% CI 1.1–3.4], and those with recent hospitalisations [OR 2.5, 95% CI 1.2–5.4]. Conclusions: IBD patients prioritised the remission of physical symptoms as treatment goals and they were less frequently concerned about medications and their side effects. Patients’ demographics, IBD characteristics, and health care utilisation patterns can predict specific types of concerns/goals

Hopanoid lipids: from membranes to plant–bacteria interactions

International audienceLipid research represents a frontier for microbiology, as showcased by hopanoid lipids. Hopanoids, which resemble sterols and are found in the membranes of diverse bacteria, have left an extensive molecular fossil record. They were first discovered by petroleum geologists. Today, hopanoid-producing bacteria remain abundant in various ecosystems, such as the rhizosphere. Recently, great progress has been made in our understanding of hopanoid biosynthesis, facilitated in part by technical advances in lipid identification and quantification. A variety of genetically tractable, hopanoid-producing bacteria have been cultured, and tools to manipulate hopanoid biosynthesis and detect hopanoids are improving. However, we still have much to learn regarding how hopanoid production is regulated, how hopanoids act biophysically and biochemically, and how their production affects bacterial interactions with other organisms, such as plants. The study of hopanoids thus offers rich opportunities for discovery

Microclimate, an inseparable part of ecology and biogeography

Abstract Microclimate science has developed into a global discipline. Microclimate science is increasingly used to understand and mitigate climate and biodiversity shifts. Here, we provide an overview of the current status of microclimate ecology and biogeography, and where this field is heading next. We showcase the recent advances in data acquisition, such as novel field sensors and remote sensing methods. We discuss microclimate modelling, mapping, and data processing, including accessibility of modelling tools, advantages of mechanistic and statistical modelling, and solutions for computational challenges that have pushed the state-of-the-art of the field. We highlight the latest research on interactions between microclimate and organisms, including how microclimate influences individuals, and through them populations, communities, and entire ecosystems and their processes. We also briefly discuss recent research on how organisms shape microclimate from the tropics to the poles. Microclimates are also important in ecosystem management under climate change. We showcase new research in microclimate management with examples from biodiversity conservation, forestry, and urban ecology. We discuss the importance of microrefugia in conservation and how to promote microclimate heterogeneity. We identify major knowledge gaps that need to be filled for further advancing microclimate methods, investigations, and applications. These gaps include spatiotemporal scaling of microclimate data, mismatches between macroclimate and microclimate in predicting responses of organisms to climate change, and the need for more evidence on the outcomes of microclimate management. &nbsp; Biosketch The authors are participants of the Microclimate Ecology and Biogeography conference held in Antwerp, Belgium in 2022.

Microclimate, an important part of ecology and biogeography

Brief introduction: What are microclimates and why are they important?: Microclimate science has developed into a global discipline. Microclimate science is increasingly used to understand and mitigate climate and biodiversity shifts. Here, we provide an overview of the current status of microclimate ecology and biogeography in terrestrial ecosystems, and where this field is heading next. Microclimate investigations in ecology and biogeography: We highlight the latest research on interactions between microclimates and organisms, including how microclimates influence individuals, and through them populations, communities and entire ecosystems and their processes. We also briefly discuss recent research on how organisms shape microclimates from the tropics to the poles. Microclimate applications in ecosystem management: Microclimates are also important in ecosystem management under climate change. We showcase new research in microclimate management with examples from biodiversity conservation, forestry and urban ecology. We discuss the importance of microrefugia in conservation and how to promote microclimate heterogeneity. Methods for microclimate science: We showcase the recent advances in data acquisition, such as novel field sensors and remote sensing methods. We discuss microclimate modelling, mapping and data processing, including accessibility of modelling tools, advantages of mechanistic and statistical modelling and solutions for computational challenges that have pushed the state‐of‐the‐art of the field. What's next?: We identify major knowledge gaps that need to be filled for further advancing microclimate investigations, applications and methods. These gaps include spatiotemporal scaling of microclimate data, mismatches between macroclimate and microclimate in predicting responses of organisms to climate change, and the need for more evidence on the outcomes of microclimate management
