A statistical analysis protocol for the time-differentiated target temperature management after out-of-hospital cardiac arrest (TTH48) clinical trial
Background: The TTH48 trial aims to determine whether prolonged duration (48 hours) of targeted temperature management (TTM) at 33 (+/- 1) degrees C results in better neurological outcomes compared to standard duration (24 hours) after six months in comatose out-of-hospital cardiac arrest (OHCA) patients.Methods: TTH48 is an investigator-initiated, multicentre, assessor-blinded, randomised, controlled superiority trial of 24 and 48 hours of TTM at 33 (+/- 1) degrees C performed in 355 comatose OHCA patients aged 18 to 80 years who were admitted to ten intensive care units (ICUs) in six Northern European countries.The primary outcome of the study is the Cerebral Performance Category (CPC) score observed at six months after cardiac arrest. CPC scores of 1 and 2 are defined as good neurological outcomes, and CPC scores of 3, 4 and 5 are defined as poor neurological outcomes. The secondary outcomes are as follows: mortality within six months after cardiac arrest, CPC at hospital discharge, Glasgow Coma Scale (GCS) score on day 4, length of stay in ICU and at hospital and the presence of any adverse events such as cerebral, circulatory, respiratory, gastrointestinal, renal, metabolic measures, infection or bleeding.With the planned sample size, we have 80% power to detect a 15% improvement in good neurological outcomes at a two-sided statistical significance level of 5%.Discussion: We present a detailed statistical analysis protocol (SAP) that specifies how primary and secondary outcomes should be evaluated. We also predetermine covariates for adjusted analyses and pre-specify sub-groups for sensitivity analyses. This pre-planned SAP will reduce analysis bias and add validity to the findings of this trial on the effect of length of TTM on important clinical outcomes after cardiac arrest
Variation in follow-up for children born very preterm in Europe
Background: Children born very preterm (<32 weeks of gestation) face high risks of neurodevelopmental and health difficulties compared with children born at term. Follow-up after discharge from the neonatal intensive care unit is essential to ensure early detection and intervention, but data on policy approaches are sparse. Methods: We investigated the characteristics of follow-up policy and programmes in 11 European countries from 2011 to 2022 using healthcare informant questionnaires and the published/grey literature. We further explored how one aspect of follow-up, its recommended duration, may be reflected in the percent of parents reporting that their children are receiving follow-up services at 5 years of age in these countries using data from an area-based cohort of very preterm births in 2011/12 (N = 3635). Results: Between 2011/12 and 22, the number of countries with follow-up policies or programmes increased from 6 to 11. The policies and programmes were heterogeneous in eligibility criteria, duration and content. In countries that recommended longer follow-up, parent-reported follow-up rates at 5 years of age were higher, especially among the highest risk children, born <28 weeks’ gestation or with birthweight <1000 g: between 42.1% and 70.1%, vs. <20% in most countries without recommendations. Conclusions: Large variations exist in follow-up policies and programmes for children born very preterm in Europe; differences in recommended duration translate into cross-country disparities in reported follow-up at 5 years of age

Genome sequencing provides insight into the reproductive biology, nutritional mode and ploidy of the fern pathogen Mixia osmundae
Mixia osmundae (Basidiomycota, Pucciniomycotina) represents a monotypic class containing
an unusual fern pathogen with incompletely understood biology. We sequenced and analyzed
the genome of M. osmundae, focusing on genes that may provide some insight into its
mode of pathogenicity and reproductive biology.
Mixia osmundae has the smallest plant pathogenic basidiomycete genome sequenced to
date, at 13.6 Mb, with very few repeats, high gene density, and relatively few significant gene
family gains.
The genome shows that the yeast state of M. osmundae is haploid and the lack of segregation
of mating genes suggests that the spores produced on Osmunda spp. fronds are probably
asexual. However, our finding of a complete complement of mating and meiosis genes suggests
the capacity to undergo sexual reproduction. Analyses of carbohydrate active enzymes
suggest that this fungus is a biotroph with the ability to break down several plant cell wall
components.
Analyses of publicly available sequence data show that other Mixia members may exist on
other plant hosts and with a broader distribution than previously known.Keywords: Fungal genomics, Myxomycetes, CAZy, Osmunda spp., Biotrophic fungi, Sporogenesi
Fluid challenges in intensive care: the FENICE study A global inception cohort study
Fluid challenges (FCs) are one of the most commonly used therapies in critically ill patients and represent the cornerstone of hemodynamic management in intensive care units. There are clear benefits and harms from fluid therapy. Limited data on the indication, type, amount and rate of an FC in critically ill patients exist in the literature. The primary aim was to evaluate how physicians conduct FCs in terms of type, volume, and rate of given fluid; the secondary aim was to evaluate variables used to trigger an FC and to compare the proportion of patients receiving further fluid administration based on the response to the FC.This was an observational study conducted in ICUs around the world. Each participating unit entered a maximum of 20 patients with one FC.2213 patients were enrolled and analyzed in the study. The median [interquartile range] amount of fluid given during an FC was 500 ml (500-1000). The median time was 24 min (40-60 min), and the median rate of FC was 1000 [500-1333] ml/h. The main indication for FC was hypotension in 1211 (59 %, CI 57-61 %). In 43 % (CI 41-45 %) of the cases no hemodynamic variable was used. Static markers of preload were used in 785 of 2213 cases (36 %, CI 34-37 %). Dynamic indices of preload responsiveness were used in 483 of 2213 cases (22 %, CI 20-24 %). No safety variable for the FC was used in 72 % (CI 70-74 %) of the cases. There was no statistically significant difference in the proportion of patients who received further fluids after the FC between those with a positive, with an uncertain or with a negatively judged response.The current practice and evaluation of FC in critically ill patients are highly variable. Prediction of fluid responsiveness is not used routinely, safety limits are rarely used, and information from previous failed FCs is not always taken into account

Skilling the bay - Geelong regional labour market profile: Briefing report twoÂ
The briefing paper presents a description and analysis of the employment profile of residents in the Regional Geelong Area (RGA). The focus is on RGA residents, the skills they possess, where they acquire work and how this has changed over time. Given that at least 20 per cent of the employed population work outside the Area, this means that there is no tight relation between residents' skills and where these skills are employed. This report draws out the implications of the employment profile of the RGA residents with reference to the character and potential of the local labour market. Of note, there are a number of Federal, State and Local Government initiatives that are underway to stimulate employment within the region as well as to reinforce the employment profile of the Area. By considering the skills profile and educational qualifications of Geelong residents and where they seek employment, including their distribution across employment sectors, it is possible to understand the implications of how the population make use of their qualifications and skills sets and where they work, inside and outside the Area. This is the key stepping stone for an understanding of the employment activity within the RGA and the composition of this regional economy as a Manufacturing and Service one. Such an evaluation provides the foundation for the identification of three major sectors for further examination as well as a consideration of the broader themes around jobs and skills transition. It also allows an understanding of the interrelationship between different sectors: manufacturing and service sectors, construction, and transport and logistics. This will enable an understanding of the skills and training potential in the region
