mbolysis was significantly associated with favorable clinical outcome and successful recanalization in the group with a medial ICAC pattern, but not in the group with an intimal ICAC pattern.

Sudden death is one of the most common causes of death among patients on hemodialysis. Thioredoxin inhibitor Although hyperphosphatemia is a well-known risk factor for cardiovascular and all-cause deaths, the studies focusing on the relationship between serum phosphate levels and the risk of sudden death are limited. This study aimed to clarify the relationship between serum phosphate levels and the risk of sudden death in patients on hemodialysis.

This is a multicenter, longitudinal, and observational study. A total of 3505 patients, registered in the Q-Cohort Study, who underwent maintenance hemodialysis, and were followed up for 10 years, were included. Patients were divided into quartiles on the basis of baseline serum phosphate levels Q1 (n=886), <4.2mg/dL; Q2 (n=837), 4.2-4.8mg/dL; Q3 (n=908), 4.9-5.6mg/dL; and Q4 (n=874), ≥5.7mg/dL. Associations between baseline serum phosphate levels and sudden death were analyzed using the Cox proportional hazards model and the Fine-Gray regression model.

During the follow-up period, 227 patients died from sudden death. The risk for sudden death was significantly higher in the highest quartile (Q4) than in the lowest quartile (Q1) as the reference group (multivariable-adjusted hazard ratios and 95% confidence intervals Q1, 1.00; Q2, 1.15 [0.77-1.70], Q3, 1.31 [0.89-1.93], and Q4, 1.72 [1.14-2.59]; hazard ratio for every 1-mg/dL increase in the serum phosphate level, 1.23 [1.09-1.39]; p<0.001).

Hyperphosphatemia is independently associated with an elevated risk of sudden death in patients on hemodialysis.

Transcutaneous oxygen pressure (TcpO

) is used in patients with suspected critical limb ischemia (CLI). Sinusoidal changes (SC~) in TcpO

are found in patients with Cheyne-Stokes respiration (CSR). We aimed to determine the characteristics of TcpO

changes at rest in patients with suspected CLI, define the objective criteria for SC~TcpO

patterns (SC+), and estimate the prevalence of SC+ in our population and its impact on the outcome.

We retrospectively analyzed 300 chest TcpO

recordings performed in a 16-month period. We determined the presence/absence of SC~TcpO

by visual analysis. We determined the acceptable error in the regularity of peaks of the cross-correlation with ROC curve analysis, among patients with typical SC~TcpO

and non-sinusoidal patterns. Then, we defined SC+as a minimum of five peaks, a standard deviation of TcpO

>1.25mmHg, an error in regularity of peaks of the cross-correlation < 10%, and a cycle length between 30 and 100s. In patients included until October 2019, we compared the outcome as a function of SC+or SC- with Cox models.

Mathematical detection of SC+found that 43 patients (14.3%) fulfilled all four defined criteria at the chest level, but only 23 did so at the limb level. In the follow-up of 207 patients, the presence of Sc~TcpO

at the chest significantly increased the risk of mortality hazard ratio 2.69 [95%CI 1.37-5.30]; p<0.005.

SC~TcpO

is frequent, and is associated with a poor outcome in patients with suspected CLI.

The transition of macrophage to foam cells is a major hallmark of early stage atherosclerotic lesions. This process is characterized by the accumulation of large cytoplasmic lipid droplets containing large quantities of cholesterol esters (CE), triacylglycerol (TAG) and phospholipid (PL). Although cholesterol and CE metabolism during foam cell formation has been broadly studied, little is known about the role of the glycerolipids (TAG and PL) in this context. Here we studied the contribution of glycerolipid synthesis to lipid accumulation, focusing specifically on the first and rate-limiting enzyme of the pathway glycerol-3-phosphate acyltransferase (GPAT).

We used RAW 264.7cells and bone marrow derived macrophages (BMDM) treated with oxidized LDL (oxLDL).

We showed that TAG synthesis is induced during the macrophage to foam cell transition. The expression and activity of GPAT3 and GPAT4 also increased during this process, and these two isoforms were required for the accumulation of cell TAG and PL. Compared to cells from wildtype mice after macrophage to foam cell transition, Gpat4

BMDM released more pro-inflammatory cytokines and chemokines, suggesting that the activity of GPAT4 could be associated with a decrease in the inflammatory response, probably by sequestering signaling precursors into lipid droplets.

Our results provide evidence that TAG synthesis directed by GPAT3 and GPAT4 is required for lipid droplet formation and the modulation of the inflammatory response during the macrophage-foam cell transition.

Freedom of movement and choice of positioning in labour and birth is known to enhance physiological processes and positive experiences for women during childbirth. Continuous foetal monitoring technologies that enable mobility in labour for women with complex pregnancies, such as wireless CTG, have been marketed for clinical use in most high resource settings since 2003 but there is a paucity of midwifery literature about its clinical use. The aim of this survey was to determine how often, and for whom, wireless and beltless technologies are being used in maternity settings across Australia and New Zealand and to identify any barriers to their uptake.

A survey tool developed by Watson et al. (2018) for use in the United Kingdom was adapted for the Australian/New Zealand context. One Maternity Unit Manager or key midwifery clinician from each of 208 public and private hospitals across Australia and New Zealand was invited by email to participate in an online survey between October 2019 and January 2020. Descriptive statistics were used to describe the characteristics of the facilities and the frequency of availability of the monitors.
