Medical nutrition therapy and clinical outcomes in critically ill adults: a European multinational, prospective observational cohort study (EuroPN)

BACKGROUND: Medical nutrition therapy may be associated with clinical outcomes in critically ill patients with prolonged intensive care unit (ICU) stay. We wanted to assess nutrition practices in European intensive care units (ICU) and their importance for clinical outcomes. METHODS: Prospective multinational cohort study in patients staying in ICU ≥ 5 days with outcome recorded until day 90. Macronutrient intake from enteral and parenteral nutrition and non-nutritional sources during the first 15 days after ICU admission was compared with targets recommended by ESPEN guidelines. We modeled associations between three categories of daily calorie and protein intake (low:  20 kcal/kg; > 1.2 g/kg) and the time-varying hazard rates of 90-day mortality or successful weaning from invasive mechanical ventilation (IMV). RESULTS: A total of 1172 patients with median [Q1;Q3] APACHE II score of 18.5 [13.0;26.0] were included, and 24% died within 90 days. Median length of ICU stay was 10.0 [7.0;16.0] days, and 74% of patients could be weaned from invasive mechanical ventilation. Patients reached on average 83% [59;107] and 65% [41;91] of ESPEN calorie and protein recommended targets, respectively. Whereas specific reasons for ICU admission (especially respiratory diseases requiring IMV) were associated with higher intakes (estimate 2.43 [95% CI: 1.60;3.25] for calorie intake, 0.14 [0.09;0.20] for protein intake), a lack of nutrition on the preceding day was associated with lower calorie and protein intakes (− 2.74 [− 3.28; − 2.21] and − 0.12 [− 0.15; − 0.09], respectively). Compared to a lower intake, a daily moderate intake was associated with higher probability of successful weaning (for calories: maximum HR 4.59 [95% CI: 1.5;14.09] on day 12; for protein: maximum HR 2.60 [1.09;6.23] on day 12), and with a lower hazard of death (for calories only: minimum HR 0.15, [0.05;0.39] on day 19). There was no evidence that a high calorie or protein intake was associated with further outcome improvements. CONCLUSIONS: Calorie intake was mainly provided according to the targets recommended by the active ESPEN guideline, but protein intake was lower. In patients staying in ICU ≥ 5 days, early moderate daily calorie and protein intakes were associated with improved clinical outcomes. Trial registration NCT04143503, registered on October 25, 2019.

Deliberate self-harm in female patients with affective disorders: Investigation of personality structure and affect regulation by means of Operationalized Psychodynamic Diagnostics

This study investigated psychodynamically relevant dimensions in female depressive patients with and without deliberate self-harm (DSH). DSH is often observed in depressive patients and frequently shows a correlation with personality disorders. Forty female depressive patients with and without DSH were investigated after recovery from acute depressive pathology by means of "operationalized psychodynamic diagnostics" (OPD). Patients with DSH had a significantly lower level of integration in the OPD dimension "structure," and their "interpersonal relationships" showed dysfunctional interaction patterns. They also had a significantly higher rate of personality disorders. These results underline the significance of aspects of personality structure in female depressive patients with DSH, and enable a deeper understanding of their dysfunctional defense strategies, the connections with underlying disturbed affect regulation, and vicious circles in the therapeutic transference-countertransference relationship. OPD has been shown to be a useful tool for empirical research into therapeutically relevant dimensions of personality

Extreme value analysis of Munich air pollution data

Three different approaches are presented to model extreme values of is fitted daily airpollution data. A generalized extreme values distribution to the monthly maxima of daily concentration measures. For the exceedances of a high threshold depending on the data the parameters of the generalized Pareto distribution were estimated. To get information about the relationship of the exceedance of the air quality standard and possible predictors logistic regression is applied. Results and their interpretation are given for daily average concentrations of O_3 and of NO_2 at two monitoring sites within the city of Munich.
