The variety of magnetic properties exhibited by paramagnetic lanthanoids provides outstanding information in NMR-based structural biology and therefore can be a very useful tool for characterizing lanthanoid-binding proteins. Because of their dependence on the relative positions of the protein nuclei and of the lanthanoid ion, the paramagnetic restraints (PCS, PRDC and PRE) provide information on structure and dynamics of proteins. In this Chapter, we cover the use of lanthanoids in structural biology including protein sample preparation, NMR experiments and data interpretation.Lanthanide biochemistry has experienced a revival in recent years owing to the discovery of new biomolecular platforms that are amenable to bind, sequester, or transport lanthanide ions. This has inherently created a need for physicochemical methods that report on lanthanide-containing macromolecular systems. In this chapter, the use of spectrophotometric methods to study the stability of lanthanide-macromolecule complexes in solution is discussed. Indeed, lanthanide ions have unique spectral properties in the ultraviolet, visible, and near-infrared domains that set them apart from the more common elements encountered in biochemistry, and these unique features can be leveraged to study, in a quantitative and robust manner, the solution chemistry of their biorelevant species (Kd, pH stability, temperature profile, etc.). This chapter aims at bringing a method that has been established and validated in the small molecule chemistry field to this new era of lanthanide biochemistry.
Liver transplantation (LT) has undergone dynamic developments in recent decades. In Germany, the Federal Joint Committee (G-BA) recently tightened the guidelines regarding the minimum number of transplantations a center should perform annually. The aim of the study presented here, was to analyze recent trends in hospital mortality due to LT in Germany.

Standardized hospital discharge data (2008-2017) from the Federal Statistical Office of Germany were used to establish hospital mortality after LT and case volume distribution among centers performing <20 LT annually (low volume centers, LVC), 20-49 LT (medium volume centers, MVC), and ≥ 50 LT (high volume centers, HVC).

Data from 9254 LT procedures were evaluated. The annual frequency of LT fell from n = 984 (2008) to n = 747 (2017), and over the same period the hospital mortality for all LT procedures went down from 15.8% to 11.0%. Hospital mortality was associated with age (<16 years 5.3% to 60-69 years 17.4%); however, there was no further increase in patients ≥ 70 years (16.5%). Univariate analysis revealed association of increased hospital mortality with liver disease etiology, the necessity for relaparotomy, and prolonged mechanical ventilation. The proportion of LT procedures performed in LVC and MVC increased and that in HVC decreased. LVC had higher hospital mortality than MVC/HVC, but this effect was dependent on patient age and disease etiology.

Our study showed that differences in mortality rate after LT among centers (LVC vs. ATG-019 purchase MVC/HVC) were dependent on patient age and disease etiology. This should be taken into account when discussing the overall organization of LT in Germany.

Sudden and unexpected postnatal collapse is a rare event with potentially dramatic consequences. Intervention approachesare limited, but hypothermia has been considered after postnatal collapse. The aim of this study was to analyse sudden and unexpected postnatal collapse cases that underwent therapeutic hypothermia in the five Portuguese hypothermia centres.

In this multicentre, retrospective and descriptive study, clinical, ultrasonography, amplitude-integrated electroencephalography and brain magnetic resonance findings of newborns with postnatal collapse that underwent therapeutic hypothermia are reported (2010 - 2018). Statistical analysis was performed by using IBM SPSS Statistics version 21.

Twenty-two cases of sudden and unexpected postnatal collapse were referred for therapeutic hypothermia (82% outborn), all ≥ 36 weeks, with Apgar 5´ ≥ 8. Collapse occurred during the first two hours in 73% (all < 24 hours), 50% during skin-to-skin care, 55% related to feeding and 23% during co-bedding. Modestfeeding and skin-to-skin care should continue to be widely promoted.
In our national sample of 22 infants who suffered sudden and unexpected postnatal collapse and underwent therapeutic hypothermia, a significant proportion had poor outcomes. Absolute conclusions from our experience with hypothermia in postnatal collapse cannot be drawn, but systematic reporting of cases and long-term clinical evaluation would facilitate understanding of the real benefits of hypothermia. As this procedure has not been validated with clinical trials for this indication, its use should be considered on a case-by-case approach. The potentially avoidable nature of unexpected postnatal collapse is evident from its association with certain behaviours and risk factors. Surveillance practices during the first hours should be implemented, whilst the benefits of breastfeeding and skin-to-skin care should continue to be widely promoted.Objectives Food insecurity (FI) is a correlate of poor health throughout the life course. This study examines relationships between FI and reported prediabetes among middle-high school students taking a school-based survey. Methods Data are from the 2019 Minnesota Student Survey (N = 125,375). Logistic regression was used to examine relationships between youth past month FI and reported prediabetes in analyses adjusting for demographics, low quality dietary intake (fast food and sugar sweetened beverage), and cardiometabolic indicators (physical activity, sleep duration, body mass index). Analyses were stratified by youth race-ethnic identification. Results Almost one in 20 youth reported past month FI. In fully adjusted models, the associations between youth FI and prediabetes differed by race-ethnic identification, and were robust to sociodemographic, diet, and cardiometabolic correlates for some groups (eg, NH black, African, African-American students [AOR 1.88, 95% CI 1.12-3.14]; Hispanic, Latino/a students [AOR 1.
