CPX-351, a liposomal encapsulation of cytarabine and daunorubicin at a synergistic 51 molar ratio, is indicated for adults with newly diagnosed, therapy-related acute myeloid leukemia or acute myeloid leukemia with myelodysplasia-related changes. In preclinical species, this article demonstrated (1) similar release of cytarabine and daunorubicin by CPX-351 in plasma; (2) similar patterns of metabolism of cytarabine and daunorubicin following administration of CPX-351 versus non-liposomal cytarabine/daunorubicin combination; (3) prolonged tissue exposure to CPX-351; (4) dramatically different tissue distribution of cytarabine and daunorubicin following administration of CPX-351 versus non-liposomal combination (tissueplasma ratios generally 1, respectively); and (5) dramatically lower unbound plasma and tissue concentrations of cytarabine and daunorubicin following administration of CPX-351 versus non-liposomal combination. Together, these results provide insight into the safety profile of CPX-351, as well as mechanisms that drive the improved efficacy observed for CPX-351 versus the conventional 7 + 3 cytarabine/daunorubicin regimen in clinical studies.The whiA (NCgl1527) gene from Corynebacterium glutamicum plays a crucial role during cell growth, and WhiA is recognized as the transcription factor for genes involved in cell division. In this study, we assessed the regulatory role of the gene in cell physiology. Transcription of the gene was specifically downregulated by the thiol-specific oxidant, diamide, and by heat stress. Cells exposed to diamide showed decreased transcription of genes involved in cell division and these effects were more profound in ΔwhiA cells. In addition, the ΔwhiA cells showed sensitivity to thiol-specific oxidants, DNA-damaging agents, and high temperature. Further, downregulation of sigH (NCgl0733), the central regulator in stress responses, along with master regulatory genes in cell metabolism, was observed in the ΔwhiA strain. Moreover, the amount of cAMP in the ΔwhiA cells in the early stationary phase was only at 30% level of that for the wild-type strain. Collectively, our data indicate that the role of whiA is to downregulate genes associated with cell division in response to heat or thiol-specific oxidative stress, and may suggest a role for the gene in downshifting cell metabolism by downregulating global regulatory genes when growth condition is not optimal for cells.Respiratory dysfunction is one of the most devastating and life-threatening deficits that occurs following cervical spinal cord injury (SCI). Assisted breathing with mechanical ventilators is a necessary part of care for many cervical injured individuals, but it is also associated with increased risk of secondary complications such as infection, muscle atrophy and maladaptive plasticity. Pre-clinical studies with epidural stimulation (EDS) have identified it as an alternative/additional method to support adequate lung ventilation without mechanical assistance. The full potential of EDS, however, may be limited by spinal inhibitory mechanisms within the injured spinal cord. The goal of the present work is to assess the potential improvement for EDS in combination with pharmacological disinhibition of spinal circuits following complete high cervical SCI. All experiments were performed in decerebrate, unanesthetized, non-paralyzed (n = 13) and paralyzed (n = 8) adult Sprague-Dawley rats 6 h following a complete C1 transection. The combination of high-frequency EDS (HF-EDS) at the C4 spinal segment with intrathecal delivery of GABA and glycine receptors antagonists (GABAzine and strychnine, respectively) resulted in significantly increased phrenic motor output, tidal volume and amplitude of diaphragm electrical activity compared to HF-EDS alone. Thus, it appears that spinal fast inhibitory mechanisms limit phrenic motor output and present a new neuropharmacological target to improve paced breathing in individuals with cervical SCI.
Robotic pancreaticoduodenectomy (RPD) has gradually been accepted as it has overcome some of the limitations of laparoscopic surgery. Outcomes following RPD in elderly patients are still uncertain. This study aimed to evaluate the safety and feasibility of RPD in elderly patients.

The demographics and perioperative outcomes of a consecutive series of patients who underwent RPD between January 2018 and September 2019, were retrospectively analyzed. selleck Patients were divided into 2 groups elderly patients (≥75 years) and younger patients (<75 years).

Of 431 patients who were included in this study, 77 were elderly patients and 354 were younger patients. Elderly patients had a significantly higher ASA score than younger patients (P<0.001). There were no significant differences in operative time, estimated blood loss and blood transfusion rate between groups (P>0.05). Elderly patients had significantly higher morbidity and longer postoperative hospital stay than younger patients (49.3% vs. 31.1%, P=0.002; 22.8 vs. 13.3 days, P<0.001, respectively). However, the reoperation, 90-day readmission and mortality rates were comparable in the two groups (P>0.05). Multivariate analysis demonstrated that a higher ASA score was the only independent factor for postoperative morbidity (OR 2.02, 95% CI 1.06-3.88, P=0.03), while old age was not (OR 0.81, 95% CI 0.36-1.81, P=0.80).

This study demonstrated that RDP was safe and feasible in elderly patients. Age should not be a contraindication to RPD. Elderly patients with careful patient selection should be considered for RPD.

Sensitized patients awaiting heart transplantation spend a longer time on the waitlist and have higher mortality. We are now able to further characterize sensitization by discriminating antibodies against class I and II, but the differential impact of these has not been assessed systematically.

Using United Network for Organ Sharing data (2004-2015), we analyzed 17,361 adult heart transplant patients whose class I and II panel reactive antibodies were reported. Patients were divided into 4 groups class I and II ≤25% (group 1); class I ≤25% and class II ˃25% (group 2); class II ≤25% and class I >25% (group 3); and both class I and II >25% (group 4). Outcomes assessed were treated rejection at 1-year mortality, all-cause mortality, and rejection-related mortality. Compared with group 1, only group 4 was associated with a higher risk of treated rejection at 1 year (odds ratio 1.31, 95% confidence interval [CI] 1.05-1.64), all-cause mortality (hazard ratio 1.24, 95% CI 1.06-1.46), and mortality owing to rejection (subhazard ratio 1.
