Objective: To determine whether absence of end-diastolic flow in the umbilical artery and/or fetal aorta impacts postnatal neuro-development in preterm-born children.
Methods: The study group, consisting of 43 fetuses with absent end-diastolic flow in the umbilical artery and/or fetal aorta, was compared with a control group, consisting of 30 fetuses, matching for gestational age but with normal doppler-flow results. The children's neuro-developmental status was assessed using the 'Munich functional developmental diagnostics' (MFDD), between the 2nd and 3rd year of life.
Results: Gestational age at birth was 33 + 6 weeks in the study group and 34 + 4 weeks in the control group. A brain-sparing effect was observed in 37.3% of fetuses in the study group compared with 10.0% in the control group (p = 0.014). For all seven MFDD domains, the number of children with deficiencies was higher in the study group. For the domains perception, active speech and comprehension this effect was statistically significant (p < 0.05). Overall, 30.2% of children in the study group and 16.7% of the control group had pathologic test results (p < 0.013).
Conclusion: Pathological doppler-flow in the umbilical artery and/or fetal descending aorta in preterm born children is associated with neuro-developmental deficiencies. Intensive pediatric care is recommended to mitigate these deficiencies during early childhood.

Proteomic, metabolomic and lipidomic profiles in community acquired pneumonia for differentiating viral and bacterial infections.

Community-acquired pneumonia (CAP) has a significant impact on public health, especially in light of the recent SARS-CoV-2 pandemic. To enhance disease characterization and improve understanding of the underlying mechanisms, a comprehensive analysis of the plasma lipidome, metabolome and proteome was conducted in patients with viral and bacterial CAP infections, including those induced by SARS-CoV-2. Lipidomic, metabolomic and proteomic profiling were conducted on plasma samples of 69 patients suffering either from viral or bacterial CAP.

Introduction: Linezolid is a broadly used antibiotic to treat complicated infections caused by gram-positive bacteria. Therapeutic drug monitoring of linezolid concentrations is recommended to maximise its efficacy and safety, mainly haematological toxicity. Different pharmacokinetic/pharmacodynamic targets have been proposed to improve linezolid exposure: the ratio of the area under the concentration-time curve during a 24-hour period to minimum inhibitory concentration (MIC) between 80 and 120; percentage of time that the drug concentration remains above the MIC during a dosing interval greater than 85% and the trough concentration between 2 and 7 mg/L.

Diaphragm samples of the right side from 42 COVID-19 critically ill patients were analyzed and correlated with the type and length of mechanical ventilation (MV), ventilatory parameters, prone positioning, and use of sedative drugs. The mean number of fibers was 550±626.

Association between pupillary examinations and prognosis in patients with out-of-hospital cardiac arrest who underwent extracorporeal cardiopulmonary resuscitation: a retrospective multicentre cohort study.

Background: In some cases of patients with out-of-hospital cardiac arrest (OHCA) who underwent extracorporeal cardiopulmonary resuscitation (ECPR), negative pupillary light reflex (PLR) and mydriasis upon hospital arrival serve as common early indicator of poor prognosis. However, in certain patients with poor prognoses inferred by pupil findings upon hospital arrival, pupillary findings improve before and after the establishment of ECPR. The association between these changes in pupillary findings and prognosis remains unclear.
