Stillbirth is generally defined as a death prior to birth at or after 22 weeks' gestation. It remains a major public health concern globally. Antenatal interventions may reduce stillbirths and improve maternal and neonatal outcomes in settings with high rates of stillbirth. There are several key antenatal strategies that aim to prevent stillbirth including nutrition, and prevention and management of infections.

To summarise the evidence from Cochrane systematic reviews on the effects of antenatal interventions for preventing stillbirth for low risk or unselected populations of women.

We collaborated with Cochrane Pregnancy and Childbirth's Information Specialist to identify all their published reviews that specified or reported stillbirth; and we searched the Cochrane Database of Systematic Reviews (search date 29 Feburary 2020) to identify reviews published within other Cochrane groups. The primary outcome measure was stillbirth but in the absence of stillbirth data, we used perinatal mortality (both ss different settings, indicating the need to carefully understand the context in which these interventions were tested. Further high-quality RCTs are needed to evaluate the effects of antenatal preventive interventions and which approaches are most effective to reduce the risk of stillbirth. Stillbirth (or fetal death), perinatal and neonatal death need to be reported separately in future RCTs of antenatal interventions to allow assessment of different interventions on these rare but important outcomes and they need to clearly define the target populations of women where the intervention is most likely to be of benefit. As the high burden of stillbirths occurs in low- and middle-income countries, further high-quality trials need to be conducted in these settings as a priority.Many previous studies have identified associations between gene expression, measured using high-throughput genomic platforms, and quantitative or dichotomous traits. However, we note that health outcome and disease status measurements frequently appear on an ordinal scale, that is, the outcome is categorical but has inherent ordering. Identification of important genes may be useful for developing novel diagnostic and prognostic tools to predict or classify stage of disease. Gene expression data are usually high-dimensional, meaning that the number of genes is much larger than the sample size or number of patients. Herein we describe some existing frequentist methods for modeling an ordinal response in a high-dimensional predictor space. Following Tibshirani (1996), who described the LASSO estimate as the Bayesian posterior mode when the regression coefficients have independent Laplace priors, we propose a new approach for high-dimensional data with an ordinal response that is rooted in the Bayesian paradigm. We show that our proposed Bayesian approach outperforms existing frequentist methods through simulation studies. We then compare the performance of frequentist and Bayesian approaches using a study evaluating progression to hepatocellular carcinoma in hepatitis C infected patients.This renin-angiotensin system (RAS) interpretation is focused on differences in tissue dependence on RAS and on the topological hierarchy that allows mediators to act only on downstream tissues. Dependence of tissues on RAS Tested by expectation maximization clustering of the RNA human tissue expression (https//biogps.org/). ACE and vasoconstrictive AT1R clustered with the prorenin receptor. ACE2 and dilatory MAS1 clustered with nine RAS-related genes, highly expressed in Liver; Cardiac_Myocytes; Skeletal_Muscle; Uterus; Kidney; Lung; Small_Intestine; Smooth_Muscle. RAS and stress accumulation While prorenin is active after binding to its receptor, binding of soluble renin increases its enzymatic activity several times. Increased renin secretion multiplies the overall capacity for producing Ang I, leading to hypertension and increased vascular resistance. Coronavirus infection and comorbidities Cardiorespiratory failure during infection is linked to the previously altered RAS role in lungs and myocardium. Reduced vasodilation by ACE2 lead to vasoconstriction and suboptimal tissue perfusion patterns. Also see the video abstract here https//www.youtube.com/watch?v=Jf0Iped-Mws.

Cerebrospinal fluid (CSF) analysis is a sensitive tool for evaluating patients with neurologic diseases but is rarely specific. Biomarkers can be measured from any bodily fluid and can be useful indicators for the presence, severity, and prognosis of diseases.

This study was designed to evaluate if CSF lactate can be used as a biomarker in dogs with central nervous system disease.

Peripheral venous blood and CSF were collected from 49 dogs with various intracranial diseases to evaluate correlations between blood and CSF lactate levels. Total nucleated cell count (TNCC) and CSF protein concentrations were also evaluated. All samples obtained were divided into normal (NG) and abnormal (AG) dogs based on a TNCC of ≤5 and >5cells/μL and a protein concentration of ≤25 and >25mg/dL, respectively. The AG dogs were further subdivided into those having <100 TNCCs/µL (AGL) and those having >100 TNCCs/µL (AGH). read more They were also subdivided into groups based on seizure activity (AGS), and inflammatory (AGI), or neoplastic diseases (AGN), and the respective lactate concentrations were then compared.

Lactate concentrations were significantly increased in CSF and venous blood samples in the AG compared with the NG dogs, but no differences were found among the individual disease processes. In all dogs, CSF lactate concentrations were higher than venous blood lactate levels; however, no direct correlation between CSF and blood lactate concentrations was identified.

Cerebrospinal fluid lactate can be used as a biomarker in clinical settings as it can be measured via a commercially available lactometer immediately after collection without the need for special instrumentation or laboratory personnel.
