Cystic fibrosis (CF) airways feature high extracellular levels of the IL-1 family of proinflammatory mediators. These mediators are cleavage products of caspase-1, the final protease in the inflammasome cascade. Due to the proven chronic presence of reprogrammed neutrophils in the CF airway lumen, understanding inflammasome signaling in these cells is of great importance to understand how disease is perpetuated in this milieu. Here, we hypothesized that CF airway neutrophils contribute to chronic inflammation, in part, via the packaging of inflammasome-inducing signals in extracellular vesicles (EVs). We confirmed that CF airway fluid is enriched in IL-1α, IL-1β, and IL-18, and that CF airway neutrophils up-regulate the activating receptor IL-1R1. Meanwhile, down-modulatory signals such as IL-1R2 and IL-1RA are unchanged. Active caspase-1 itself is present in CF airway fluid EVs, with neutrophil-derived EVs being most enriched. Using a transmigration model of CF airway inflammation, we show that CF airway fluid EVs are necessary and sufficient to induce primary granule exocytosis by naïve neutrophils (hallmark of reprogramming) and concomitantly activate caspase-1 and IL-1β production by these cells and that the addition of triple-combination highly effective CFTR modulator therapy does not abrogate these effects. Finally, EVs from activated neutrophils can deliver active caspase-1 to primary tracheal epithelial cells and induce their release of IL-1α. These findings support the existence of a feed-forward inflammatory process by which reprogrammed CF airway neutrophils bypass 2-step control of inflammasome activation in neighboring cells (naïve neutrophils and epithelial cells) via the transfer of bioactive EVs.Lactate levels are surrogate markers of malperfusion in patients presenting with type A aortic dissections. Lactate measurement is simple, easy to perform, universally available, and thus can be an important tool for predicting mortality. However, the discriminatory power varies between studies and no cut-off point has been defined that can determine outcomes in the most reliable fashion. The risk prediction based on lactate levels can be improved when combined with other clinical and laboratory prognostic factors. Further studies with a much larger sample size, need to be carried out using serial measurements at well-defined time points to try and identify a cut-off value. The addition of lactate values to existing risk prediction scores or developing a new score based on it should be the subject of future research.Several recently developed methods have the potential to harness machine learning in the pursuit of target quantities inspired by causal inference, including inverse weighting, doubly robust estimating equations and substitution estimators like targeted maximum likelihood estimation. There are even more recent augmentations of these procedures that can increase robustness, by adding a layer of cross-validation (cross-validated targeted maximum likelihood estimation and double machine learning, as applied to substitution and estimating equation approaches, respectively). While these methods have been evaluated individually on simulated and experimental data sets, a comprehensive analysis of their performance across real data based simulations have yet to be conducted. In this work, we benchmark multiple widely used methods for estimation of the average treatment effect using ten different nutrition intervention studies data. A nonparametric regression method, undersmoothed highly adaptive lasso, is used to generate the simulated distribution which preserves important features from the observed data and reproduces a set of true target parameters. For each simulated data, we apply the methods above to estimate the average treatment effects as well as their standard errors and resulting confidence intervals. Based on the analytic results, a general recommendation is put forth for use of the cross-validated variants of both substitution and estimating equation estimators. We conclude that the additional layer of cross-validation helps in avoiding unintentional over-fitting of nuisance parameter functionals and leads to more robust inferences.Physically based models have been part of many risk assessment studies concerning pesticide or nutrient transport within (sub)catchments or at plot scale, but they are only poorly validated for simulating the transport of veterinary medicinal products. Veterinary medicinal products not only pose a risk to the quality of our waters but also tend to accumulate in soils, where they are associated with the appearance of resistant bacteria and long-term leaching. In this study, the physically based leaching model MACRO 5.2 was applied for simulating sulfamethazine (SMZ) transport over a period of more than 10 yr. The model was set up using reversible kinetic adsorption and equilibrium adsorption forming non-extractable residues. Two different calibration periods were used to estimate uncertainties in predicted SMZ leaching associated with calibration based on short-term data. Using the whole period for model calibration, SMZ leaching could be simulated adequately, but parameter ranges were wide due to correlation between the parameters. When using only the first period for calibration, the quality of the prediction strongly depended on the information content of the data set. The calculation of temporal sensitivity indices revealed that the effect of complex sorption parameters on the model output increased with time. Thus, parameters that appeared insensitive in a short-term calibration were required for reliable long-term simulations. In conclusion, a temporal sensitivity analysis beyond the calibration period might identify parameters that were not constrained enough by the calibration procedure. This could help to confirm leaching predictions even for periods without sampling data.
To examine population changes in 5-year survival for people in South Australia diagnosed with acute leukaemia during 1980-2016, by socio-demographic characteristics.

Retrospective analysis of South Australian Cancer Registry data for the period 1980-2016.

All South Australian residents diagnosed with primary acute lymphoblastic leukaemia (ALL) or acute myeloid leukaemia (AML) during 1980-2016.

5-year disease-specific survival and disease-specific mortality.

Crude 5-year disease-specific survival was 58% (95% CI, 54-61%) for the 1035 people diagnosed with ALL during 1980-2016, and 18% (95% CI, 17-20%) for the 2814 people diagnosed with AML. Survival improved steadily across the study period from 44% (95% CI, 35-52%) for people with ALL diagnosed during 1980-1984 to 69% (95% CI, 63-75%) for those diagnosed during 2010-2016; and from 9% (95% CI, 5-15%) to 23% (95% CI, 20-26%) for people diagnosed with AML. Disease-specific mortality increased with age, but was not influenced by socio-economic status or remoteness of residence. After adjusting for other factors, rates of change in risk of leukaemia-related death were greater for younger than older patients with ALL (for interaction P=0.004) or AML (P=0.005), but were not significantly influenced by socio-economic status or remoteness.

Five-year survival for people with acute leukaemia in South Australia continuously improved during 1980-2016, and socio-economic status and remoteness did not influence survival. It improved markedly for younger patients (under 50 years of age). However, survival is still relatively poor, especially for people over 50 years with AML.

To determine the distribution of ABO RhD blood groups in Australia in 2019.

Retrospective analysis of blood group data for blood donors (Australian Red Cross Lifeblood National Blood Management System) and for people whose blood type was determined in samples submitted for analysis by hospital-based or private pathology agencies.

All Australian states and territories, 1 January - 31 December 2019.

Proportions of donors and patients, by ABO blood group and RhD status. These proportions were compared with published data for 1993-94 first-time blood donors.

A total of 1318751 valid ABO RhD blood group results were provided by 28 of 41 invited pathology agencies (including 245 of 324 approved health providers, 76%). Valid ABO RhD data were available for 490491 blood donors, including 103798 first-time donors (21.2%). Vemurafenib cell line Blood group prevalence based on samples typed by pathology services was O RhD+, 38.4%; O RhD-, 6.5%; A RhD+, 32.0%; A RhD-, 5.6%; B RhD+, 11.8%; B RhD-, 1.5%; AB RhD+, 3.7%; and AB RhD-, 0.5% (totals RhD+, 85.9%; RhD-, 14.1%). The distribution based on typing of first-time blood donors was similar. The overall proportion of RhD+ first-time donors rose from 81% in 1993-94 to 83.8% in 2019; the proportion of groups B and AB RhD+ RBC units issued declined from 9.8% in 2010-11 to 6.9% of all RBC units in 2019-20, while that of O RhD- RBC units increased from 11.7% to 17.4%.

Our national assessment of ABO RhD prevalence in Australia provides updated information for re-evaluating blood and blood product collection and holdings in light of changes in population demographic characteristics.

Patients treated with anti-CD38 monoclonal antibodies (mAbs) had significantly lower CD38+ Tregs than those not treated (0.9 vs. 13.2/μl). Late-responders, whose antibody titres increased from weeks 4-12 after the second vaccination, had significantly lower CD38+ Treg counts than non-late-responders (2.5 vs. 10.3/μl). Antibody titres in patients with lower CD38+ Treg levels were maintained from weeks 4-12 but decreased in those with higher CD38+ Treg levels. Therefore, depletion of CD38+ Tregs by anti-CD38 mAbs may induce a durable response to mRNA-COVID-19 vaccination.
The severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) pandemic threatened to oversaturate hospitals worldwide, necessitating rapid patient discharge to preserve capacity for the most severe cases. This need, as well as the high risk of SARS-CoV-2 transmission, led many hospitals to implement remote patient monitoring (RPM) programs for SARS-CoV-2 positive patients in an effort to provide care that was safe and preserve scarce resources.

The aim of this study is to provide an integrative review of peer-reviewed literature on different RPM programs that were implemented for SARS-CoV-2 positive patients including their strengths and challenges.

A search was conducted for peer reviewed literature using PubMed, CINAHL, OVID, and Google Scholar. Peer-reviewed studies written in English or Spanish and published between 2019 and 2021 on RPM of SARS-CoV-2-positive patients were considered. Information was extracted according to a qualitative content analysis method, informed by the Comparison of Mobile Patient Monitoring Systems Framework.
