Human milk can prevent the development of necrotizing enterocolitis (NEC). Human milk is rich in cargo-carrying exosomes that participate in intercellular communication. This study investigated the effects of term and preterm human milk-derived exosomes, and elucidated their lipid expression profiles.
Milk from healthy mothers is collected who have delivered full-term or preterm infants, and exosomes are isolated and quantified. Administration of term and preterm milk exosomes significantly enhances epithelial proliferation and migration in vitro, and ameliorates the severity of NEC in vivo. A total of 395 lipids are identified in term and preterm human milk-derived exosomes. Bioinformatics analysis and western blotting reveal that top 50 lipids regulate intestinal epithelial cell function via the Extracellular-Signal-Regulated Kinase/Mitogen Activated Protein Kinase (ERK/MAPK) pathway.
This study reveals for the first time the lipidomic complexities in exosomes derived from preterm and term milk. Itacitinib The results provide novel mechanistic insight on how human milk prevents the development of NEC.

Immature platelets in the circulation can be measured as immature platelet fraction (IPF). Limited data exist regarding IPF during the course of an acute myocardial infarction (AMI), the association between IPF and extent of cardiac damage, and the long-term prognostic implications of IPF in patients with AMI.
To examine the temporal course of IPF during the first month after AMI, the association between IPF and extent of cardiac damage, and the long-term prognostic effect of IPF in AMI patients.
Patients with AMI treated with percutaneous coronary intervention (PCI) were examined. IPF was evaluated by a Sysmex XN-3000 autoanalyzer, at 4 time points baseline; one day post-PCI; 3days post-PCI, and 30days post-PCI. The association between peak troponin-T levels and IPF was evaluated. One-year clinical outcomes (cardiac hospitalization, urgent revascularization, or death) were assessed.
One hundred patients were included, mean age was 59.5±11.3years, 82 were men, 27 had diabetes, and 54 were hospitalized with ST-segment elevation myocardial infarction (STEMI) and 46 with non-ST segment elevation myocardial infarction (NSTEMI). The levels of IPF modestly decreased a day after PCI but did not change in subsequent measurements. Peak troponin-T level was significantly associated with the levels of IPF at all 4 time points. IPF levels three days post-PCI were associated with the composite clinical outcome at 1year.
The levels of IPF following AMI remain relatively stable over a one-month period. Higher levels of IPF during the acute phase of AMI appear to be associated with worse cardiac outcomes at 1year.

It uses predefined k-mers to retrieve only the reads of interest from the FASTQ file and calls genotypes by aligning retrieved reads locally. KATK does not use data about known polymorphisms and has NC (no call) as the default genotype. The reference or variant allele is called only if there is sufficient evidence for their presence in data. Thus it is not biased against rare variants or de-novo mutations. With simulated datasets, we achieved a false-negative rate of 0.23% (sensitivity 99.77%) and a false discovery rate of 0.19%. Calling all human exonic regions with KATK requires 1-2 h, depending on sequencing coverage.We would like to thank Razaq et al for their comments regarding our manuscript titled "Sarcopenia in Children with End Stage Liver Disease on the Transplant Waiting list". We appreciate their comments regarding the application of sarcopenia in children.
Accurately identifying patients with psoriasis (PsO) is crucial for generating real-world evidence on PsO disease course and treatment utilization.
We developed nine claims-based algorithms for PsO using a combination of the International Classification of Diseases (ICD)-9 codes, specialist visit, and medication dispensing using Medicare linked to electronic health records data (2013-2014) in two healthcare provider networks in Boston, Massachusetts. We calculated positive predictive value (PPV) and 95% confidence interval (CI) for each algorithm using the treating physician's diagnosis of PsO via chart review as the gold standard. Among the confirmed PsO cases, we assessed their PsO disease activity.
The nine claims-based algorithms identified 990 unique patient records. Of those, 918 (92.7%) with adequate information were reviewed. The PPV of the algorithms ranged from 65.1 to 82.9%. An algorithm defined as ≥1 ICD-9 diagnosis code for PsO and ≥1 prescription claim for topical vitamin D agents showed the highest PPV (82.9%). The PPV of the algorithm requiring ≥2 ICD-9 diagnosis codes and ≥1 prescription claim for PsO treatment excluding topical steroids was 81.1% but higher (82.5%) when ≥1 diagnosis was from a dermatologist. Among 411 PsO patients with adequate information on PsO disease activity in EHRs, 1.5-5.8% had no disease activity, 31.3-36.8% mild, and 26.9-35.1% moderate-to-severe across the algorithms.
Claims-based algorithms based on a combination of PsO diagnosis codes and dispensing for PsO-specific treatments had a moderate-to-high PPV. These algorithms can serve as a useful tool to identify patients with PsO in future real-world data pharmacoepidemiologic studies.
