    57; 95% CI=0.26-0.88, p=0.008) and peak cTnT (β=0.97; 95%CI=0.57-1.38, p<0.001). Altogether, MVD plus MVO predicted EF (β=-0.18; 95%CI=-0.28–0.07, p=0.002).

    Even in patients with limited amount of MVO, EF may be impaired by MVD. MVO and MVD have different predictors, which probably reflect their different pathogenesis.

Vacuolar-type H+ -translocating ATPases and a pyrophosphatase are thought to enable vacuoles to accumulate protons against their electrochemical potential. However, recent studies pointed to the ATPase located at the trans-Golgi network/early endosome (TGN/EE) to contribute to vacuolar acidification in a manner not understood as of now. Here, we combined experimental data and computational modeling to test different hypotheses for vacuolar acidification mechanisms. For this, we analyzed different models with respect to their ability to describe existing experimental data. To better differentiate between alternative acidification mechanisms, new experimental data have been generated. By fitting the models to the experimental data, we were able to prioritize the hypothesis in which vesicular trafficking of Ca2+ /H+ -antiporters from the TGN/EE to the vacuolar membrane and the activity of ATP-dependent Ca2+ -pumps at the tonoplast might explain the residual acidification observed in Arabidopsis mutants defective in vacuolar proton pump activity. The presented modeling approach provides an integrative perspective on vacuolar pH regulation in Arabidopsis and holds potential to guide further experimental work.

    Given that emergency procedures must be performed immediately and without the possibility of sufficiently informing and preparing a patient, the lived experiences of patients who undergo emergency procedures and those who undergo elective procedures may well differ. Elucidating the lived experiences of patients who underwent percutaneous coronary intervention (PCI) with stent implantation in an emergency situation is crucial because such knowledge might prove helpful in tailoring post-procedure interventions intended to improve the lives of PCI patients.

    To describe the experiences of patients 1 month after they underwent emergency PCI with coronary stent implantation.

    Cohen’s phenomenology was applied in this study. This method combines the characteristics of descriptive (Husserlian) phenomenology with those of interpretative (Gadmerian) phenomenology, and it is by nature an inductive approach. The participants were enrolled 1 month after undergoing PCI with coronary stent implantation. They were interledge of the lived experiences of patients who underwent emergency PCI with coronary stent implantation is fundamental in identifying aspects that warrant tailored interventions.

    Epidural tunneling could help with prolonged catheterization and be effective in preventing infection and dislodgement. selleck products However, epidural tunneling techniques carry a risk of catheter shear or needlestick injuries.

    This study aimed to examine the safety of our epidural tunneling technique in terms of catheter shear.

    This study was designed as a double-blinded, single-crossover, in vitro study. Each of the operators performed two techniques to create a subcutaneous tunnel. We compared outcomes between the control tunneling technique (group C) and our improved technique (group I). Microscopic findings of catheter shear were assessed as the primary outcome. Secondary outcomes included the tension and displacement required to break the epidural catheter and the frequency of catheter breakage due to catheter shear. Data were analyzed using the Fisher’s exact test and Mann-Whitney U test. A p-value of <.05 was considered statistically significant.

    Ten catheters were assessed in each group. The frequency of catheter shear was 10% in group I and 90% in group C (odds ratio, 0.019; 95% confidence interval , 0.01-0.31; p<.001). The frequency of catheter breakage due to catheter shear was significantly lower in group I (0%) than in group C (80%; p<.001). The mean tension and displacement required to break the catheter were significantly higher in group I than in group C (4.13±0.37N vs. 3.14±1.00N; mean difference, 0.99N; 95% CI, 0.25-1.73N; p=.013 and 222±59.9mm vs. 122±77.7mm; mean difference, 100mm; 95% CI, 34.1-165mm; p=.005).

    Our improved epidural tunneling technique, which was designed for pediatric cases, could reduce the risk of catheter shear.

    Caesarean section (CS) can be life-saving for both mother and child, but in Nigeria the CS rate remains low, at 2.7% of births. We aimed to estimate the rate of CS and early neonatal mortality in Nigeria according to obstetric risk and socio-economic background and to identify factors associated with CS.

    We used the 2018 Nigeria Demographic and Health Survey, encompassing 33924 live births within the last 5years, to estimate the CS rate and early neonatal mortality rate (ENMR) by obstetric risk group, informed by the Robson classification. The CS rate and ENMR were assessed within each Robson group and stratified by socio-economic background. Logistic regression analyses were used to explore determinants of CS.

    Almost three-quarters (72.4%) of all births were to multiparous women, with a singleton baby of normal birthweight, thus a low-risk group similar to Robson 3, and with a CS rate of 1.0%. CS rates in the two high-risk groups (multiple pregnancy and preterm/low birthweight) were low, 7.1% (95% CI 5.2-9.7) and 1.8 % (95% CI 1.4-2.4), respectively. The ENMR was particularly high for multiple pregnancy (175 per 1000 live births; 95% CI 131-230). Greater number of antenatal visits, unwanted pregnancy, multiple pregnancy, household wealth, maternal education, Christians/Others versus Muslims and referral during childbirth were positively associated with CS.

    Inequitable access to CS is not limited to socio-economic determinants, but also related to obstetric risk factors, calling for increased efforts to improve access to CS for high-risk pregnancies.
