Development and implementation of guidelines for the management of depression: a systematic review
2020
To evaluate the development and implementation of clinical practice guidelines for the management of depression globally.We conducted a systematic review of existing guidelines for the management of depression in adults with major depressive or bipolar disorder. For each identified guideline, we assessed compliance with measures of guideline development quality (such as transparency in guideline development processes and funding, multidisciplinary author group composition, systematic review of comparative efficacy research) and implementation (such as quality indicators). We compared guidelines from low- and middle-income countries with those from high-income countries.We identified 82 nati…
Elective surgery system strengthening: development, measurement, and validation of the surgical preparedness index across 1632 hospitals in 119 count…
2022
© 2022 The Author(s). Published by Elsevier Ltd. This is an Open Access article under the CC BY 4.0 licenseBackground: The 2015 Lancet Commission on global surgery identified surgery and anaesthesia as indispensable parts of holistic health-care systems. However, COVID-19 exposed the fragility of planned surgical services around the world, which have also been neglected in pandemic recovery planning. This study aimed to develop and validate a novel index to support local elective surgical system strengthening and address growing backlogs. Methods: First, we performed an international consultation through a four-stage consensus process to develop a multidomain index for hospital-level assess…
Global perspective of familial hypercholesterolaemia: a cross-sectional study from the EAS Familial Hypercholesterolaemia Studies Collaboration (FHSC)
2021
Background The European Atherosclerosis Society Familial Hypercholesterolaemia Studies Collaboration (FHSC) global registry provides a platform for the global surveillance of familial hypercholesterolaemia through harmonisation and pooling of multinational data. In this study, we aimed to characterise the adult population with heterozygous familial hypercholesterolaemia and described how it is detected and managed globally. Methods Using FHSC global registry data, we did a cross-sectional assessment of adults (aged 18 years or older) with a clinical or genetic diagnosis of probable or definite heterozygous familial hypercholesterolaemia at the time they were entered into the registries. Dat…
First Early Permian Paleomagnetic Pole for the Yili Block and its Implications for Late Paleozoic Postorogenic Kinematic Evolution of the SW Central …
2018
International audience; We conducted a paleomagnetic study on the Early Permian volcanic and sedimentary rocks, and the Neoproterozoic mafic dikes in the Yili Block, NW China. Magnetite and hematite were proven to be the principal magnetic remanence carriers. Demagnetizations revealed stable characteristic remanence magnetizations with a sole reversed magnetic polarity. The magnetic remanence of only the Early Permian strata turned out to be primary based on positive fold tests; meanwhile, the magnetic remanence age of the mafic dikes is ambiguous. Accordingly, the first Early Permian paleomagnetic pole for the Yili Block is calculated at λ = 81.5°N, φ = 256.5°E, N = 11, and A95 = 10.9°. Co…
Initial-Stage Suicide Bereavement Experiences: A Case Study.
2022
This study aimed to shed light on the initial-stage bereavement experiences of an individual bereaved by suicide, at three months from the loss of his spouse to suicide. A semi-structured in-depth interview was conducted with the individual, a man in his thirties. The data were analyzed using qualitative assimilation analysis, based on the Assimilation Model and the Assimilation of Problematic Experiences Scale (APES). The APES ratings of the interview revealed that the individual’s bereavement was associated with the earlier stages of APES (all scoring under 3.5). In addition, the swift and frequent fluctuations in the APES ratings gave indications that the bereavement was unstable and co…
Longitudinal Changes in Suicide Bereavement Experiences : A Qualitative Study of Family Members over 18 Months after Loss
2023
Family members bereaved by their loved ones’ suicidal death normally undergo a complicated and lengthy bereavement process. In this qualitative case study, we explored longitudinal changes in the suicide bereavement process by applying assimilation analysis, based on the Assimilation Model (AM) and the Assimilation of Problematic Experiences Scale (APES), to longitudinal interview data collected from two Chinese suicide-bereaved individuals within the first 18 months after their loss. The results showed that over time the participants both progressed in adapting to their traumatic losses. Assimilation analysis both effectively elaborated the difference in the inner world of the bereaved and…
Guidelines for the use and interpretation of assays for monitoring autophagy (4th edition) 1
2021
Contains fulltext : 232759.pdf (Publisher’s version ) (Closed access) In 2008, we published the first set of guidelines for standardizing research in autophagy. Since then, this topic has received increasing attention, and many scientists have entered the field. Our knowledge base and relevant new technologies have also been expanding. Thus, it is important to formulate on a regular basis updated guidelines for monitoring autophagy in different organisms. Despite numerous reviews, there continues to be confusion regarding acceptable methods to evaluate autophagy, especially in multicellular eukaryotes. Here, we present a set of guidelines for investigators to select and interpret methods to…

In 2008, we published the first set of guidelines for standardizing research in autophagy. Since then, this topic has received increasing attention, and many scientists have entered the field.

Despite numerous reviews, there continues to be confusion regarding acceptable methods to evaluate autophagy, especially in multicellular eukaryotes. Here, we present a set of guidelines for investigators to select and interpret methods to examine autophagy and related processes, and for reviewers to provide…
