The decrease in sST2 levels in pg/mL was significantly higher in the atorvastatin compared to the rosuvastatin group (-255 [-383 to -109.8 vs - 151 [-216 to -69], P = .003). There was a significant reduction in N-terminal pro-brain natriuretic peptide and interleukin-6 levels in both groups, yet the reduction was comparable in both groups.

The study results suggest that lipophilic atorvastatin is superior to hydrophilic rosuvastatin in increasing left ventricular ejection fraction and reducing fibrosis marker sST2 in HF patients. Trial registration ID NCT03255044, registered on 21 August 2017.

Simulations are an essential tool for investigating scenarios in pharmacokinetics-pharmacodynamics. The models used during simulation often include the effect of highly correlated covariates such as weight, height and sex, and for children also age, which complicates the construction of an in silico population. selleck screening library For this reason, a suitable and representative patient population is crucial for the simulations to produce meaningful results. For simulation in paediatric patients, international growth charts from the World Health Organization (WHO) and the Centers for Disease Control and Prevention (CDC) provide a reference, but these may not always be representative for specific populations, such as malnourished children with HIV or acutely unwell children.

We present a workflow to construct a virtual paediatric patient population using WHO and CDC growth charts, suggest piecewise linear functions to adjust the median of the growth charts by sex and age, and suggest visual diagnostics to compare with the target population. We applied this workflow in a population of 1206 HIV-positive African children, consisting of 19 742 observations with weight ranging from 3.8 to 79.7 kg, height from 55.5 to 180 cm, and an age between 0.40 and 18 years.

Before adjustment, the WHO and CDC charts produced weights and heights higher compared to the observed data. After applying our methodology, we could simulate weight, height, sex and age combinations in good agreement with the observed data.

The methodology presented here is flexible and may be applied to other scenarios where WHO and CDC growth standards might not be appropriate. In addition we provide R scripts and a large ready-to-use paediatric population.

Mounting evidence suggests disproportionate coronavirus disease 2019 (COVID-19) hospitalizations and deaths because of racial disparities. The association of race in a cohort of gynecologic oncology patients with severe acute respiratory syndrome-coronavirus 2 infection is unknown.

Data were abstracted from gynecologic oncology patients with COVID-19 infection among 8 New York City area hospital systems. A multivariable mixed-effects logistic regression model accounting for county clustering was used to analyze COVID-19-related hospitalization and mortality.

Of 193 patients who had gynecologic cancer and COVID-19, 67 (34.7%) were Black, and 126 (65.3%) were non-Black. Black patients were more likely to require hospitalization compared with non-Black patients (71.6% [48 of 67] vs 46.0% [58 of 126]; P = .001). Of 34 (17.6%) patients who died from COVID-19, 14 (41.2%) were Black. Among those who were hospitalized, compared with non-Black patients, Black patients were more likely to have ≥3 comorbidities (8ities in COVID-19 outcomes among Black patients are critical.
Cold storage of platelets in plasma maintains hemostatic function and is an attractive alternative to room temperature platelets (RTPs). We have recently shown that functional differences between cold-stored platelets (CSPs) and RTPs after 5-day storage are associated with mitochondrial respiration and that CSPs in platelet (PLT) additive solution (PAS) can maintain hemostatic function for at least 15 days.

This study tested the hypothesis that cold storage in PAS preserves mitochondrial integrity by reducing PLT apoptosis. CSPs and RTPs in plasma or PAS were stored and assayed for up to 15 days for mitochondrial function and integrity, mitochondrial-associated mRNA transcript expression, apoptotic proteins, and apoptotic flow cytometry metrics.

CSP preserved mitochondria-associated mRNA comparable to baseline levels, improved mitochondrial respiration, and minimized depolarization to Day 15. Additionally, CSPs had minimal induction of caspases, preservation of plasma membrane integrity, and low expression of pro-apoptotic Bax. Storage in PAS appeared to be protective for RTPs in some parameters and enhanced the effects of CSPs.

Mitochondrial function and molecular analyses defined CSP priming as distinctly different from the well-documented RTP storage lesion. While current blood bank storage at room temperature is limited to 5 to 7 days, refrigeration and storage in PAS for up to 15 days may represent an opportunity to enhance inventories and access to PLT hemostatic support for bleeding patients.

Although they constitute an essential habitat for fish and invertebrate species, large accumulations of Sargassum in coastal areas generate several economic, environmental, and health impacts. It is important to recognize the species forming these aggregates, and identify the metabolites they produce, allowing for its exploitation, and therefore, better management practices. NMR metabolic profiling is a technique that can discriminate samples while detecting their unique or differential chemical features, and has been successfully used in the study and classification of several algal species. The present investigation studied the metabolic profiling of Sargassum species found on strandings at Puerto Morelos (Quintana Roo) east coast of the Mexican Caribbean.
