Development of a panel dataset from the IAB Establishment Panel cross-sectional data

"The IAB Establishment Panel now consists of 12 waves from 1993-2004, which are available for research use in the Research Data Centre of the Federal Employment Agency at the Institute for Employment Research. Due to repeated surveys of the same establishments, individual processes within the establishments can be studied in both cross-sectional and longitudinal terms. Cross-sectional evaluations of various waves and the production of a longitudinal or panel dataset require different tasks to be solved. Researchers must check across the individual survey years whether the variable values have remained identical or whether values are absent or new ones have been added. In addition, the measurement levels of the variables must be checked and any differences must be harmonised. Further, the time period in question can alter (e.g. financial year or first half-year). The purpose of such checks is to guarantee the comparability of the variables beyond the analysis period. The above examples illustrate that producing a panel dataset involves time-consuming processing of the individual datasets. This report has been written as a tool to support users in producing a panel dataset on the basis of data from the IAB Establishment Panel. The Datenreport consists of the development of a panel dataset containing variables that tend to be frequently used, in our experience. The panel dataset is available in the Research Data Centre and can be used both via remote data access and during research visits. The STATA and SPSS program code used to produce the dataset is available as a download, enabling users to integrate additional variables into the program code used with relative ease. The program codes can also be modified with the aid of the test data. This Datenreport is structured as follows: following a brief description of the IAB Establishment Panel, the structure of the panel dataset is presented. Next, Chapter 4 presents the variables for the dataset in the form of tables and details the use of the program codes. Appendix 1 describes each of the variables in the panel dataset, also detailing the values and any restrictions or problems occurring. Appendix 2 presents frequency counts1 of the variables used. The program codes in SPSS and STATA are contained in a separate document."

Zero Entropy Interval Maps And MMLS-MMA Property

We prove that the flow generated by any interval map with zero topological entropy is minimally mean-attractable (MMA) and minimally mean-L-stable (MMLS). One of the consequences is that any oscillating sequence is linearly disjoint with all flows generated by interval maps with zero topological entropy. In particular, the M\"obius function is orthogonal to all flows generated by interval maps with zero topological entropy (Sarnak's conjecture for interval maps). Another consequence is a non-trivial example of a flow having the discrete spectrum.Comment: 12 page

Compact Electrochromic Optical Recording of Bioelectric Potentials

Electrochromic optical recording (ECORE) is a label-free method that utilizes electrochromism to optically detect electrical signals in biological cells with a high signal-to-noise ratio and is suitable for long-term recording. However, ECORE usually requires a large and intricate optical setup, making it relatively difficult to transport and to study specimens on a large scale. Here, we present a compact ECORE apparatus that drastically reduces the spatial footprint and complexity of the ECORE setup whilst maintaining high sensitivity. An autobalancing differential photodetector automates common-mode noise rejection, removing the need for manually adjustable optics, and a compact laser module conserves space compared to a typical laser mount. The result is a simple, easy-to-use, and relatively low cost system that achieves a sensitivity of 16.7 {\mu}V (within a factor of 5 of the shot noise limit), and reliably detects action potentials from Human-induced pluripotent stem cell (HiPSC) derived cardiomyocytes. This setup can be further improved to within 1.5 dB of the shot noise limit by filtering out power-line interference.Comment: 11 pages, 4 figure

Teilhabe und Grundsicherung - SGB II als Leistungssystem und Lebenslage

Das Kapitel widmet sich drei Schwerpunkten zur Teilhabe auf Grundsicherungsniveau. Es werden individuelle zeitliche Muster des SGB-II-Bezugs typisiert und Erwerbskonstellation von Paaren vor und nach dem Bezug betrachtet. Auch der Einfluss von Betriebswechseln bei erwerbstätigen Beziehenden wird untersucht: Meist sind sie mit einem höheren Stundenlohn verbunden, aber nicht jeder mündet in stabile Beschäftigung. Ferner werden Teilhabewirkungen des SGB II in den Blick genommen. Leistungsbeziehende leiden unter einer Teilhabelücke, die sich in den letzten Jahren aber verkleinert zu haben scheint. Analysen qualitativer Längsschnittdaten zeigen zudem, dass trotz dieses Trends Teilgruppen mit verschlechterten Lebensbedingungen und weiterhin großem "Leidensdruck" bestehen

High-dose Cefepime vs Carbapenems for Bacteremia Caused by Enterobacterales With Moderate to High Risk of Clinically Significant AmpC β-lactamase Production

BACKGROUND: Limited data suggest that serious infections caused by Enterobacterales with a moderate to high risk of clinically significant AmpC production can be successfully treated with cefepime if the cefepime minimum inhibitory concentration (MIC) is ≤2 µg/mL. However, isolates with a cefepime-susceptible dose-dependent (SDD) MIC of 4-8 µg/mL should receive a carbapenem due to target attainment and extended-spectrum β-lactamase (ESBL) concerns. METHODS: This was a retrospective cohort study of hospitalized patients with RESULTS: Of the 315 patients included, 169 received cefepime and 146 received a carbapenem (ertapenem n = 90, meropenem n = 56). Cefepime was not associated with an increased risk of 30-day mortality compared with carbapenem therapy (adjusted hazard ratio [aHR], 1.45; 95% CI, 0.79-2.14), which was consistent for patients with cefepime SDD isolates (aHR, 1.19; 95% CI, 0.52-1.77). Multivariable weighted Cox models identified Pitt bacteremia score \u3e4 (aHR, 1.41; 95% CI, 1.04-1.92), deep infection (aHR, 2.27; 95% CI, 1.21-4.32), and ceftriaxone-resistant AmpC-E (aHR, 1.32; 95% CI, 1.03-1.59) to be independent predictors associated with increased mortality risk, while receipt of prolonged-infusion β-lactam was protective (aHR, 0.67; 95% CI, 0.40-0.89). CONCLUSIONS: Among patients with bacteremia caused by Enterobacterales with moderate to high risk of clinically significant AmpC production, these data demonstrate similar risk of 30-day mortality for high-dose cefepime or a carbapenem as definitive β-lactam therapy

Impact of Ceftolozane-Tazobactam vs. Best Alternative Therapy on Clinical Outcomes in Patients with Multidrug-Resistant and Extensively Drug-Resistant Pseudomonas aeruginosa Lower Respiratory Tract Infections

INTRODUCTION: Infections caused by multidrug-resistant (MDR), extensively drug-resistant (XDR), and difficult-to-treat (DTR) Pseudomonas aeruginosa are increasingly challenging to combat. Ceftolozane-tazobactam (C/T) is a novel β-lactam-β-lactamase inhibitor combination now commonly used to treat MDR and XDR P. aeruginosa. Lower respiratory tract infections (LRTIs) remain the most common source of infection caused by MDR/XDR P. aeruginosa. Comparative effectiveness studies to date have been limited by the type of comparator agents (i.e., aminoglycosides and polymyxins) and the inclusion of multiple infection sources (i.e., urinary tract, abdominal, skin and soft tissue, etc.). METHODS: We performed a multicenter, retrospective analysis of adults with LRTI caused by MDR or XDR P. aeruginosa admitted from January 2014 to December 2019. We aimed to compare clinical outcomes between patients who received C/T (n = 118) versus best alternative therapy (n = 88). The primary outcome was clinical failure, defined as 30-day mortality and/or an adverse drug reaction on antibiotic therapy. RESULTS: Two hundred and six patients met inclusion criteria. The C/T group had a significantly higher proportion of XDR P. aeruginosa and ventilator-associated bacterial pneumonia (VABP). After multivariable logistic regression, C/T treatment was independently associated with a 73.3% reduction in clinical failure compared to those who received best alternative therapy (P \u3c 0.001). The number needed to harm with best alternative therapy was 3. CONCLUSION: Our results suggest that C/T is a safe and effective therapeutic regimen for patients with MDR and XDR P. aeruginosa LRTI

Clinical Characteristics Associated with Bacterial Bloodstream Coinfection in COVID-19

INTRODUCTION: Inappropriate antibiotic use in COVID-19 is often due to treatment of presumed bacterial coinfection. Predictive factors to distinguish COVID-19 from COVID-19 with bacterial coinfection or bloodstream infection are limited. METHODS: We conducted a retrospective cohort study of 595 COVID-19 patients admitted between March 8, 2020, and April 4, 2020, to describe factors associated with a bacterial bloodstream coinfection (BSI). The primary outcome was any characteristic associated with BSI in COVID-19, with secondary outcomes including 30-day mortality and days of antibiotic therapy (DOT) by antibiotic consumption (DOT/1000 patient-days). Variables of interest were compared between true BSI (n = 25) and all other COVID-19 cases (n = 570). A secondary comparison was performed between positive blood cultures with true BSI (n = 25) and contaminants (n = 33) on antibiotic use. RESULTS: Fever (\u3e 38 °C) (as a COVID-19 symptom) was not different between true BSI (n = 25) and all other COVID-19 patients (n = 570) (p = 0.93), although it was different as a reason for emergency department (ED) admission (p = 0.01). Neurological symptoms (ED reason or COVID-19 symptom) were significantly higher in the true BSI group (p \u3c 0.01, p \u3c 0.01) and were independently associated with true BSI (ED reason: OR = 3.27, p \u3c 0.01; COVID-19 symptom: OR = 2.69, p = 0.03) on multivariate logistic regression. High (15-19.9 × 10(9)/L) white blood cell (WBC) count at admission was also higher in the true BSI group (p \u3c 0.01) and was independently associated with true BSI (OR = 2.56, p = 0.06) though was not statistically significant. Thirty-day mortality was higher among true BSI (p \u3c 0.01). Antibiotic consumption (DOT/1000 patient-days) between true BSI and contaminants was not different (p = 0.34). True bloodstream coinfection was 4.2% (25/595) over the 28-day period. CONCLUSION: True BSI in COVID-19 was associated with neurological symptoms and nonsignificant higher WBC, and led to overall higher 30-day mortality and worse patient outcomes
