Optimizing the LSST Observing Strategy for Dark Energy Science : DESC Recommendations for the Wide-Fast-Deep Survey
- 2018
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- Cosmology is one of the four science pillars of LSST, which promises to be transformative for our understanding of dark energy and dark matter. The LSST Dark Energy Science Collaboration (DESC) has been tasked with deriving constraints on cosmological parameters from LSST data. Each of the cosmological probes for LSST is heavily impacted by the choice of observing strategy. This white paper is written by the LSST DESC Observing Strategy Task Force (OSTF), which represents the entire collaboration, and aims to make recommendations on observing strategy that will benefit all cosmological analyses with LSST. It is accompanied by the DESC DDF (Deep Drilling Fields) white paper (Scolnic et al.). We use a variety of metrics to understand the effects of the observing strategy on measurements of weak lensing, large-scale structure, clusters, photometric redshifts, supernovae, strong lensing and kilonovae. In order to reduce systematic uncertainties, we conclude that the current baseline observing strategy needs to be significantly modified to result in the best possible cosmological constraints. We provide some key recommendations: moving the WFD (Wide-Fast-Deep) footprint to avoid regions of high extinction, taking visit pairs in different filters, changing the 2x15s snaps to a single exposure to improve efficiency, focusing on strategies that reduce long gaps (>15 days) between observations, and prioritizing spatial uniformity at several intervals during the 10-year survey.

- Background: For conditions with rare clinical outcomes, real-world treatment comparisons are challenging to design and prone to confounding.Objectives: To present a robust methodologic approach for rigorous and transparent assessment of rare outcomes using real-world data.Methods: We emulated a target trial using an active comparator, new-user design to compare dronedarone to sotalol for rhythm control in atrial fibrillation (AF) as both are recommended for similar patient phenotypes. Using one protocol, a pre-specified stepwise approach was implemented across 4 datasets (Optum CDM; IBM MarketScan; Veterans Affairs Electronic Health Records; Swedish National Patient Register). Meta-analysis was used to ensure sufficient capture of specific, rare primary outcomes (cardiovascular (CV) hospitalization and ventricular proarrhythmia) and to evaluate consistency of findings across patient populations. Steps 1–3 focused on cohort selection, propensity score matching (PSM), baseline equipoise and residual confounding assessment via negative control outcome analyses. In steps 4–6, outcomes in the individual cohorts were analyzed using an as-treated approach and Cox proportional hazards models. Step 7 included a heterogeneity assessment, meta-analysis using fixed effects models, and hypothesis testing using a hierarchical approach. In step 8, sensitivity analyses, including E-values and Inverse Probability of Censoring Weighting, were conducted to verify the robustness of findings.Results: In step 1, 35,467 sotalol and 27,955 dronedarone patients with AF who were antiarrhythmic drug-naive were identified across databases. In steps 2–3, 23,275 dronedarone patients were PS-matched to 23,275 sotalol patients. Baseline covariates were well-balanced and little-to-no residual confounding was observed via the negative control analyses. Individual HRs were estimated in steps 4–6, and, when no significant heterogeneity between databases was observed, hazard ratios (HRs) were pooled across datasets in step 7. For example, for CV hospitalization, dronedarone was superior to sotalol with no heterogeneity (HR: 0.91; 95% CI: 0.85, 0.97; Cochran Q p-value: 0.32). Eleven sensitivity analyses were conducted in step 8 and confirmed that findings were generally robust.Conclusions: An active comparator, new-user design using the target trial approach coupled with meta-analysis generated consistent findings across databases and countries using one protocol. Similar methods, including a pre-specified stepwise approach, negative control outcome, and tests for robustness should be considered for real-world studies where specific, rare outcomes need to be examined in a rigorous and transparent way.

Antibiotic Resistance : Selection in the Presence of Metals and Antimicrobials
- 2018
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The external environment is complex: Antibiotics, metals and antimicrobials do not exist in isolation but in mixtures. Human activities such as animal husbandry, fertilization of agricultural fields and human medicine release high amounts these compounds into the environment. The work in this thesis contributes to our understanding of how the selection of bacterial antibiotic resistance can be facilitated by the pollution by metals and antimicrobials. We show that low levels of antibiotics, metals and combinations thereof can lead to the selection of chromosomally encoded antibiotic resistance genes as well as a multidrug resistance plasmid. The underlying genetic and cellular mechanisms of selection identified relate to mutational changes in a plasmid-encoded metal resistance operon, and metal-associated increases in cellular membrane permeability. We further show that exposure to quaternary ammonium compounds can result in cross-resistance to antibiotics following genetic changes in genes related to efflux, membrane synthesis and transcription/translation. Taken together, the work in this thesis suggests that the stewardship of antibiotics should include prudent use of metals and antimicrobials.
