DIY Methods 2022 Conference Proceedings

As the past years have proven, the methods for conducting and distributing research that we’ve inherited from our disciplinary traditions can be remarkably brittle in the face of rapidly changing social and mobility norms. The ways we work and the ways we meet are questions newly opened for practical and theoretical inquiry; we both need to solve real problems in our daily lives and account for the constitutive effects of these solutions on the character of the knowledge we produce. Methods are not neutral tools, and nor are they fixed ones. As such, the work of inventing, repairing, and hacking methods is a necessary, if often underexplored, part of the wider research process. This conference aims to better interrogate and celebrate such experiments with method. Borrowing from the spirit and circuits of exchange in earlier DIY cultures, it takes the form of a zine ring distributed via postal mail. Participants will craft zines describing methodological experiments and/or how-to guides, which the conference organisers will subsequently mail out to all participants. Feedback on conference proceedings will also proceed through the mail, as well as via an optional Twitter hashtag. The conference itself is thus an experiment with different temporalities and medialities of research exchange. As a practical benefit, this format guarantees that the experience will be free of Zoom fatigue, timezone difficulties, travel expenses, and visa headaches. More generatively, it may also afford slower thinking, richer aesthetic possibilities, more diverse forms of circulation, and perhaps even some amount of delight. The conference format itself is part of the DIY experiment

Without vision no transition: exploring the potential of planning design studios

Representations of the future – plans, visions, scenarios – guide us in taking complex decisions in the present. In our current day and age, we face multiple societal challenges, for example, climate, ecology, and social exclusion. This makes long-term thinking more relevant than ever. However, this core idea of spatial planning as a future-oriented discipline seems to have been eroding over the years. We teach our students to critically assess what is and not so much what could be or should be. The educational format of planning design studios trains long-term thinking and students' imaginative capabilities in an experiential, real-life setting. In this contribution, we evaluate 25 years of planning studios at Utrecht University.This essay reviews the history and discusses adaptations in course design and -objectives, student involvement and -experience, and teachers' evaluations over the years. We position these empirical impressions against a brief comparison of the 'Utrecht model' with studio exercises at planning schools of other Dutch universities. We discuss whether planning studios as a form of real-life, experiential learning still succeed in triggering the long-term thinking abilities of students. We scrutinize to what extent students are still capable of thinking so far ahead and summarize both the bottlenecks and enablers for an educational environment in which long-term thinking can flourish. We suggest that the biggest challenge to fostering long-term thinking is not so much the potential of studios but rather their decreasing importance as an integrative course in the curriculum design, which may limit the efficiency of training the futures literacy of planning students

COVID-19 and late adolescent mental health

This study examined socioeconomic disparities in changes in late adolescents’ mental health between fall 2019, spring 2020, and fall 2020. Using data from 1,429 adolescents (Mage = 17.9) from tertiary vocational schools in the Netherlands, linear and latent basis growth curve models were assessed and multigroup analyses conducted. Results showed a small but significant decrease in life satisfaction and small but significant increases in emotional problems, peer relationship problems, conduct problems, and hyperactivity-inattention problems. For emotional problems and peer relationship problems, changes between fall 2019 and spring 2020 were more pronounced than changes between spring 2020 and fall 2020. For the other outcomes, decreases were linear. Mental health trajectories were largely comparable for adolescents from families with varying socioeconomic status

Examining socioeconomic disparities in changes in adolescent mental health before and during different phases of the coronavirus disease 2019 pandemic

This study examined socioeconomic disparities in changes in adolescent mental health between fall 2019 (pre-COVID-19), spring 2020 (initial coronavirus disease 2019 (COVID-19) phase), and fall 2020 (prevailing COVID-19 phase). Using data from 1429 adolescents (Mage = 17.9) from tertiary vocational schools in the Netherlands with n = 386 participating in all three waves, linear and latent basis growth curve models were assessed and multigroup analyses conducted. Results showed a small but significant decrease in life satisfaction and small but significant increases in emotional problems, peer relationship problems, conduct problems, and hyperactivity-inattention problems. For emotional problems and peer relationship problems, increases between pre-COVID-19 and the initial COVID-19 phase were more pronounced than increases between the initial and prevailing COVID-19 phase. In contrast, linear decreases were found for life satisfaction and linear increases for conduct problems and hyperactivity-inattention problems over the course of the study. Mental health patterns were largely comparable for adolescents from families with varying socioeconomic status

Treatment of vaginal vault prolapse in The Netherlands: a clinical practice survey

Introduction and hypothesis: A great variety of conservative and surgical procedures to correct vaginal vault prolapse have been reported. The aim of this study was to describe practice pattern variation—the difference in care that cannot be explained by the underlying medical condition—among Dutch gynecologists regarding treatment of vaginal vault prolapse. Methods: A clinical practice survey was conducted from March to April 2017. The questionnaire was developed to evaluate treatment of vaginal vault prolapse. All members of the Dutch Society for Urogynaecology were invited to participate in a web-based survey. Results: One hundred four Dutch gynecologists with special interest in urogynecology responded to the survey (response rate, 44%). As first-choice therapy for vaginal vault prolapse, 78% of the respondents chose pessary treatment, whereas sacrospinous fixation was the second most common therapy choice according to 64% of the respondents. Preferences on how to approach vaginal vault prolapse surgically are conflicting. Overall, the most performed surgery for vaginal vault prolapse is sacrospinous fixation, followed by laparoscopic and robotic sacrocolpopexy. Conclusions: Gynecologists in The Netherlands manage vaginal vault prolapse very differently. No standardized method could be determined for the treatment of vaginal vault prolapse in The Netherlands, and we observed practice pattern variations

Linear interaction energy based prediction of cytochrome P450 1A2 binding affinities with reliability estimation.

Prediction of human Cytochrome P450 (CYP) binding affinities of small ligands, i.e., substrates and inhibitors, represents an important task for predicting drug-drug interactions. A quantitative assessment of the ligand binding affinity towards different CYPs can provide an estimate of inhibitory activity or an indication of isoforms prone to interact with the substrate of inhibitors. However, the accuracy of global quantitative models for CYP substrate binding or inhibition based on traditional molecular descriptors can be limited, because of the lack of information on the structure and flexibility of the catalytic site of CYPs. Here we describe the application of a method that combines protein-ligand docking, Molecular Dynamics (MD) simulations and Linear Interaction Energy (LIE) theory, to allow for quantitative CYP affinity prediction. Using this combined approach, a LIE model for human CYP 1A2 was developed and evaluated, based on a structurally diverse dataset for which the estimated experimental uncertainty was 3.3 kJ mol-1. For the computed CYP 1A2 binding affinities, the model showed a root mean square error (RMSE) of 4.1 kJ mol-1 and a standard error in prediction (SDEP) in cross-validation of 4.3 kJ mol-1. A novel approach that includes information on both structural ligand description and protein-ligand interaction was developed for estimating the reliability of predictions, and was able to identify compounds from an external test set with a SDEP for the predicted affinities of 4.6 kJ mol-1 (corresponding to 0.8 pKi units).The work was supported by Innovative Medicines Initiative Joint Undertaking (IMI-JU) under grant agreement no. 115002 (eTOX), resources of which are composed of financial contribution from the European Union Seventh Framework Programme/n(FP7/20072013) and EFPIA companies in kind contribution; www.etoxproject.eu.

The levonorgestrel intrauterine system versus endometrial ablation for heavy menstrual bleeding: a cost-effectiveness analysis

OBJECTIVE: To evaluate the costs and non-inferiority of a strategy starting with the LNG-IUS compared to endometrial ablation (EA) in the treatment of heavy menstrual bleeding (HMB). DESIGN: Cost-effectiveness analysis from a societal perspective alongside a multicentre randomised non-inferiority trial. SETTING: General practices and gynaecology departments in the Netherlands. POPULATION: 270 women with HMB, aged ≥34 years old, without intracavitary pathology or future child wish. METHODS: Randomisation to a strategy starting with the LNG-IUS (n=132) or EA (n=138). The incremental cost-effectiveness ratio (ICER) was estimated. MAIN OUTCOME MEASURES: Direct medical costs and (in)direct non-medical costs were calculated. The primary outcome was menstrual blood loss after 24 months, measured with the mean Pictorial Blood Assessment Chart (PBAC)-score (non-inferiority margin 25 points). A secondary outcome was successful blood loss reduction (PBAC-score ≤75 points). RESULTS: Total costs per patient were €2,285 in the LNG-IUS strategy and €3,465 in the EA strategy (difference: €1,180). At 24 months mean PBAC-scores were 64.8 in the LNG-IUS group (N=115) and 14.2 in the EA group (N=132); difference 50.5 points (95% CI: 4.3-96.7). In the LNG-IUS group, 87% of women had a PBAC-score ≤75 points versus 94% in the EA group (RR 0.93, 95% CI: 0.85-1.01). The ICER was €23 (95% CI: €5-€111) per PBAC-point. CONCLUSIONS: A strategy starting with the LNG-IUS was cheaper than starting with EA, but non-inferiority could not be demonstrated. The LNG-IUS is reversible and less invasive and can be a cost-effective treatment option, depending on the success rate women are willing to accept
