lowed daily restraint practice to be described independently of existing routines, departmental cultures and personal attitudes. This is important to comprehensively describe restrictive practices, which is a prerequisite for the development of effective restraint reduction strategies.The role of iron-regulated mitophagy in lipid metabolism is unclear. Recent work by Long, Sanchez-Martinez et al (2022) shows that iron chelation induces a primary change in lipid metabolism that promotes fat accumulation and precedes mitophagy.The mechanisms underlying cancer metastasis remain poorly understood. Here, we report that TFAM deficiency rapidly and stably induced spontaneous lung metastasis in mice with liver cancer. Interestingly, unexpected polymerization of nuclear actin was observed in TFAM-knockdown HCC cells when cytoskeleton was examined. Polymerization of nuclear actin is causally linked to the high-metastatic ability of HCC cells by modulating chromatin accessibility and coordinating the expression of genes associated with extracellular matrix remodeling, angiogenesis, and cell migration. Mechanistically, TFAM deficiency blocked the TCA cycle and increased the intracellular malonyl-CoA levels. Malonylation of mDia2, which drives actin assembly, promotes its nuclear translocation. Importantly, inhibition of malonyl-CoA production or nuclear actin polymerization significantly impeded the spread of HCC cells in mice. Moreover, TFAM was significantly downregulated in metastatic HCC tissues and was associated with overall survival and time to tumor recurrence of HCC patients. Taken together, our study connects mitochondria to the metastasis of human cancer via uncovered mitochondria-to-nucleus retrograde signaling, indicating that TFAM may serve as an effective target to block HCC metastasis.Progressive multifocal leukoencephalopathy (PML) is an increasingly common and rapidly fatal demyelinating infection of central nervous system caused by the highly prevalent John Cunningham (JC) virus in immunocompromised individuals belonging to all age groups and genders. Human immunodeficiency virus (HIV) is the most common predisposing factor among other immunodeficient conditions leading to reactivation and multiple neurological symptoms. It has varied findings on magnetic resonance imaging (MRI) and diagnosis is confirmed by positive JC virus in cerebrospinal fluid (CSF). We report 12 confirmed cases of PML from a single academic center. We comprehensively described clinical presentations, risk factors, CSF and neuroimaging findings, treatment and outcome for these cases of PML, a rare disease. The cases were almost equivalently distributed among young and old age groups and both genders. Positive JC virus on CSF was present in the majority of cases along with mild to severe reduction in lymphocyte counts. Significant MRI changes were present in all cases ranging from T2 hypertense signals to white matter lesions in various regions. Treatment with the reversion of immune-modulators, optimization of antiviral therapy (ART), plasmapheresis (PLEX), IVIG, Mirtazapine, oral steroids, and others was started as soon as the diagnosis was made in the majority of the cases. However, PML is a rapidly fatal illness and hence, survival was only seen in 4 cases in our study. The objective of this article is to highlight the importance of early diagnosis of PML with CSF findings and neuroimaging, early reversion of immunosuppressive medications, and careful monitoring and treatment of HIV cases with goals to reduce mortality, long-term morbidity, and deficits.A successful human pregnancy requires precisely timed adaptations by the maternal immune system to support fetal growth while simultaneously protecting mother and fetus against microbial challenges. The first trimester of pregnancy is characterized by a robust increase in innate immune activity that promotes successful implantation of the blastocyst and placental development. Moreover, early pregnancy is also a state of increased vulnerability to vertically transmitted pathogens notably, human immunodeficiency virus (HIV), Zika virus (ZIKV), SARS-CoV-2, and Listeria monocytogenes. As gestation progresses, the second trimester is marked by the establishment of an immunosuppressive environment that promotes fetal tolerance and growth while preventing preterm birth, spontaneous abortion, and other gestational complications. Finally, the period leading up to labor and parturition is characterized by the reinstatement of an inflammatory milieu triggering childbirth. These dynamic waves of carefully orchestrated changes have been dubbed the "immune clock of pregnancy." Monocytes in maternal circulation and tissue-resident macrophages at the maternal-fetal interface play a critical role in this delicate balance. This review will summarize the current data describing the longitudinal changes in the phenotype and function of monocyte and macrophage populations in healthy and complicated pregnancies.

Failure to mature the fistula in patients undergoing hemodialysis leads to prolonged use of the central venous catheter (CVC) and can compromise the patency of the catheter and the arteriovenous fistula (AVF) due to thrombus development.

To evaluate hemostatic changes in patients undergoing hemodialysis with prolonged use of CVC or AVF.

Cross-sectional study with a total of 200 adult participants who were divided into the following groups Icontrol; II patients who had 5-8 months of CVC insertion; III patients who had 9-36 months of insertion; IV patients who had 5-8 months of AVF; and V patients who had 9-36 months of AVF. Platelet activation was investigated by expressions of GPIIb/IIIa and p-selectin using flow cytometry. The Elisa-thrombomodulin (TM) test was used to compare groups III and V.

The p-selectin percentage expression of group I was 15.30 (12.30-16.80), II 23.25 (20.75-30.55); and III 54.00 (44.75-59.29) were significant (p < 0.001). Groups I, IV, and V were also significant (p < 0.001). The median fluorescence for GPIIb/IIIa for groups I, II, and III were significant (p < 0.0001). As for the Elisa test, an increased absorbance of TM was verified in patients who used the CVC 4372 (3951-4733) compared with those patients who used the AVF 2162 (1932-2485) (p < 0.0001).

It can be concluded that CVC patients had a larger platelet expression of GPIIb/IIIa and p-selectin than AVF patients. selleckchem The high concentration of TM in CVC patients may suggest a greater stimulation of the intrinsic than extrinsic coagulation pathways.

Evaluating plan robustness is a key step in radiotherapy.

To develop a flexible Monte Carlo (MC)-based robustness calculation and evaluation tool to assess and quantify dosimetric robustness of intensity-modulated radiotherapy (IMRT) treatment plans by exploring the impact of systematic and random uncertainties resulting from patient setup, patient anatomy changes, and mechanical limitations of machine components.

The robustness tool consists of two parts the first part includes automated MC dose calculation of multiple user-defined uncertainty scenarios to populate a robustness space. An uncertainty scenario is defined by a certain combination of uncertainties in patient setup, rigid intrafraction motion and in mechanical steering of the following machine components angles of gantry, collimator, table-yaw, table-pitch, table-roll, translational positions of jaws, multileaf-collimator (MLC) banks, and single MLC leaves. The Swiss Monte Carlo Plan (SMCP) is integrated in this tool to serve as the backboner-friendly GUI to quantitatively assess and compare treatment plans and their robustness.

Bleeding complications during venovenous extracorporeal membrane oxygenation (V-V ECMO) can be critical. However, there is limited information on the associated risk factors. This study investigated the risk factors for bleeding complications during V-V ECMO as a bridge to recovery.

This single-center retrospective study enrolled 59 patients (bleeding and non-bleeding groups) who received V-V ECMO from 2012 to 2020, to evaluate whether peak activated partial thromboplastin time (APTT) value, lowest platelet count, and mobilization to sitting on the edge of the bed during V-V ECMO were risk factors for bleeding complications, defined according to the Extracorporeal Life Support Organization guidelines. Age, sex, body mass index, Sequential Organ Failure Assessment score, and ECMO duration before bleeding complications were covariates in the multivariate logistic regression analysis.

Thirty-one (53%) participants experienced 36 bleeding complications; the ECMO cannulation site, gastrointestinal tract, and nasopharyngeal region were the most common bleeding sites. The use of transfusion products and length of ECMO and intensive care unit stay were significantly and medical costs were non-significantly increased in the bleeding group. Peak APTT (odds ratio [OR] 1.03, 95% confidence interval [CI] 1.01-1.05, p < 0.01) was significantly associated whereas the lowest platelet count (OR 0.96, 95% CI 0.82-1.13, p=0.66) was unassociated with bleeding complications during ECMO. Achieving mobilization (OR 0.14, 95% CI 0.02-1.17, p=0.07) decreased the trend of risk for bleeding complications.

Peak APTT might be an independent modifiable factor for bleeding complications during V-V ECMO. The protective effect of mobilization during V-V ECMO requires further investigation.

We aim to explore the non-structural sugars from white wine grape pomace (WWGP) as the input carbon source for the co-production of multiple high-value products by the non-fastidious yeast Rhodotorula babjevae to create a sustainable and economically appealing process.

Water extraction of unfermented, soluble sugars from WWGP yielded extracts with similar amounts of glucose and fructose, which were used to prepare a growth medium. Rhodorotula babjevae multiplied as fast on WWGP-based medium as on a reference medium but achieved higher cell dry weight (CDW) and lower intracellular triacylglycerol accumulation (22.5% vs. 28.6%) in WWGP-based medium. In addition, R. babjevae produced mannitol and arabitol and carotenoids and secreted polyol esters of fatty acids, a rare type of glycolipid as confirmed by Fourier transform-infrared, nuclear magnetic resonance and high-performance liquid chromatography analyses. Remarkably, R. babjevae consumed simultaneously both fructose and glucose when on WWGP-based medium and left glucose practically untouched in the reference medium, evidencing a fructophilic character.

Rhodorotula babjevae, a metabolic versatile yeast, proliferated on a minimally processed extract and successfully converted glucose and fructose into high-value products.

Different chemicals with market potential can be produced through the valorization of abundant waste feedstocks generated by the wine industry to which R. babjevae can contribute.
