High-energy nuclear collisions create a quark-gluon plasma, whose initial condition and subsequent expansion vary from event to event, impacting the distribution of the eventwise average transverse momentum [P([p_{T}])]. Disentangling the contributions from fluctuations in the nuclear overlap size (geometrical component) and other sources at a fixed size (intrinsic component) remains a challenge. This problem is addressed by measuring the mean, variance, and skewness of P([p_{T}]) in ^{208}Pb+^{208}Pb and ^{129}Xe+^{129}Xe collisions at sqrt[s_{NN}]=5.

Objective: To evaluate the influence of pre-existing maternal diabetes mellitus on fetal myocardial performance index and systolic-to-diastolic duration ratio.
Methods: Prospective cohort study included 179 pregnant women between 20 and 36w6d, divided into 3 groups: Group 1 (120, normal), Group 2 (31, type 1 diabetes mellitus), and Group 3 (28, type 2 diabetes mellitus). Systolic-to-diastolic duration ratio was calculated as the sum of isovolumic contraction time and ejection time divided by the sum of isovolumic relaxation time and ventricular filling time.
Opposite effects of systemic and local conditional CD11c+ myeloid cell depletion during bleomycin-induced inflammation and fibrosis in mice.

Article Synopsis
- Elevated CD11c+ myeloid cells, including dendritic cells and macrophages, contribute to pulmonary disorders like Idiopathic Pulmonary Fibrosis (IPF), but their specific role in lung ECM accumulation and fibrosis is not well understood.
- The study aimed to explore the consequences of depleting these CD11c+ myeloid cells during induced pulmonary fibrosis in mice through both systemic and local depletion methods.
- Results indicated that systemic depletion of CD11c+ cells reduced lung inflammation and fibrosis and increased protective cytokine levels, while local depletion led to higher mortality due to acute inflammation.
Rationale & Objective: Severe hypertension (sHTN) that develops after hospital admission is prevalent in 10% of patients admitted for reasons other than HTN. sHTN is commonly treated with intravenous (IV) antihypertensives and is associated with a greater risk of acute kidney injury (AKI). Our goal was to explore whether there is heterogeneity in IV antihypertensives' effect on AKI incidence among patients who develop sHTN during hospitalization.

Methods: A retrospective cohort study was performed on pregnant women with gastroschisis fetuses and their respective newborns between 2009 and 2019. Binary logistic regression was used to determine the best prenatal ultrasound markers of complex gastroschisis and adverse perinatal outcomes.
