"COVID toes": a meta-analysis of case and observational studies on clinical, histopathological and laboratory findings.
<p><strong>Background: </strong>Coronavirus disease (COVID-19) is related to several extrapulmonary disorders; however, little is known about the clinical, laboratory and histopathological characteristics of pernio-like skin lesions associated with COVID-19 infection. <strong>Objective: </strong>To evaluate and summarize the clinical, laboratory and histopathological characteristics of pernio-like lesions reported in the literature. <strong>Methods: </strong>We conducted a search of the PubMed, SciELO and ScienceDirect databases for articles published between 1 January 2020 and 30 November 2020, following the PRISMA recommendations (PROSPERO registration ID: CRD42020225055). The target population was individuals with suspected or laboratory-confirmed COVID-19 with pernio-like lesions. Observational studies, research letters and case/series reports were all eligible for inclusion. Observational studies were evaluated using a random-effects model to calculate the weighted mean prevalence, overall mean and 95% confidence interval. We evaluated case studies using the chi-square test for dichotomous variables and the Mann-Whitney test for continuous variables. <strong>Results:</strong> A total of 187 patients from case reports and 715 patients from 18 observational studies were included. The mean age of patients was 16.6 (14.5–18.8) years. Feet were affected in 91.4% (87.0–94.4%) of patients in observational studies. The proportion of patients with a positive RT-PCR test was less than 15%. Lesion topography and morphology were associated with age. <strong>Conclusion:</strong> Lesions mostly occurred in pediatric patients, and the morphological characteristics tended to differ between pediatric and non-pediatric populations. There is a possible multifactorial component in lesion pathophysiology. The non-positivity of laboratory tests does not exclude an association with COVID-19. Chilblain-like lesions may be a late manifestation of COVID-19.</p>

<p>This is a basic reproduction package for the paper "Multi-dimensional population modelling using frbpoppy: Magnetars can produce the observed fast radio burst sky" by David Gardenier & Joeri van Leeuwen (2021).</p> <p>* arXiv: <a href="https://arxiv.org/abs/2012.06396">arXiv:2012.06396</a><br> * DOI: <a href="https://doi.org/10.1051/0004-6361/202040119">10.1051/0004-6361/202040119</a></p> <p> </p>
Risk of bias in observational studies using routinely collected data of comparative effectiveness research: a meta-research study
<p>We performed a meta-research study by searching PubMed for comparative effectiveness observational studies evaluating therapeutic interventions using routinely collected data published in high impact factor journals from 01/06/2018 to 30/06/2020. We assessed the reporting of study design (i.e., eligibility, treatment assignment, and the start of follow-up). Risk of selection bias and immortal time bias was determined by assessing if the time of eligibility, treatment assignment and the start of follow-up were synchronised to mimic the randomisation following the target trial emulation framework.</p>
Observation of robust energy transfer in the photosynthetic protein allophycocyanin using single-molecule pump-probe spectroscopy - single-molecule photon stream
<p>Photon stream used in the article "<em>Observation of robust energy transfer in the photosynthetic protein allophycocyanin using single-molecule pump-probe spectroscopy" </em> to analyze single-molecule fluorescence emission. Detected emission for single-molecule pump-probe experiments with an associated instrument response function (IRF) and background fluoresence (BG). Each detected photon is described by its time within the collected photon stream and its time relative to the excitation laser. Data is organized by sample and by date. Also included is an .xlsx document with fitted timescales for all included molecules and Matalb structure titled 'FinalDataAndStatistics.mat', which includes the final data, and statistics for the data used within the paper.</p>
