Antibiotic resistance is one of the world's greatest public health challenges and adjunct probiotic therapies are strategies that could lessen this burden. Clostridioides difficile infection (CDI) is a prime example where adjunct probiotic therapies could decrease disease incidence through prevention. Human-derived Lactobacillus reuteri is a probiotic that produces the antimicrobial compound reuterin known to prevent C. difficile colonization of antibiotic-treated fecal microbial communities. However, the mechanism of inhibition is unclear. We show that reuterin inhibits C. difficile outgrowth from spores and vegetative cell growth, however, no effect on C. difficile germination or sporulation was observed. Consistent with published studies, we found that exposure to reuterin stimulated reactive oxygen species (ROS) in C. difficile, resulting in a concentration-dependent reduction in cell viability that was rescued by the antioxidant glutathione. Sublethal concentrations of reuterin enhanced the susceptibility of vegetative C. difficile to vancomycin and metronidazole treatment and reduced toxin synthesis by C. SJ6986 cost difficile. We also demonstrate that reuterin is protective against C. difficile toxin-mediated cellular damage in the human intestinal enteroid model. Overall, our results indicate that ROS are essential mediators of reuterin activity and show that reuterin production by L. reuteri is compatible as a therapeutic in a clinically relevant model.

Children with low von Willebrand factor (VWF) activity or type 1 von Willebrand disease (VWD) have increased risk of bleeding after adenotonsillar procedures and the optimal perioperative management to minimize bleeding is unknown.

To report the effectiveness and safety of an institutional protocol in minimizing postoperative bleeding in children with type 1 VWD or low VWF activity.

We conducted a retrospective chart review in children with type 1 VWD or low VWF activity treated via an institutional protocol that utilizes repeated doses of Desmopressin acetate (DDAVP, 1-deamino 8-D arginine- vasopressin) or VWF concentrate, brief hospitalization for observation and extended use of oral epsilon aminocaproic acid (EACA).

From 2010 to 2017, 13 children underwent an adenotonsillar procedure and were treated with this protocol. Although 7.6% had minor immediate bleeding and 23% had minor delayed bleeding, no patients experienced major bleeding or required transfusion, additional surgery or other measures nies to determine the optimal strategy for safely reducing bleeding complications in these patients.Eltrombopag is a small molecule, thrombopoietin receptor agonist approved for the treatment of patients with aplastic anemia and chronic immune thrombocytopenia. It is also a polyvalent cation chelator and inhibits leukemia cell proliferation via reduction of intracellular iron. The in vivo efficacy of eltrombopag was tested against a panel of six Pediatric Preclinical Testing Consortium osteosarcoma xenografts at doses of 5 mg/kg/day (moderate dose) and 50 mg/kg/day (high dose). Eltrombopag, at moderate doses, failed to significantly improve event-free survival (EFS) in 6/6 models. At high doses, eltrombopag significantly prolonged EFS in 2/2 models, though the effect size was small. All models tested demonstrated progressive disease. While eltrombopag did not meaningfully inhibit osteosarcoma growth, it also did not stimulate tumor growth, suggesting it may be safely investigated as a supportive care agent to enhance platelet recovery post chemotherapy.Metastatic castration-resistant prostate cancer (mCRPC) is a natural sequela in advanced prostate cancer following resistance to standard treatment regimes, where patients develop with rising PSA, bone pains, and high disease volume. Further palliative treatment is the need of the hour for ensuring disease control and quality of life. In recent times, many novel methods have been evolved for these patients. Endo-radioligand therapy with Lutetium 177 prostate-specific membrane antigen 617 (Lu-177 PSMA) based on the Theranostic concept has emerged as a promising tool among these. We present here the current status of Lu177-PSMA for mCRPC patient and future directions.

Drinking alcohol with coworkers is a common practice in many occupational cultures. This practice may produce negative consequences for some employees.

We estimate the prevalence of a set of negative consequences of work-related alcohol use and identify risk factors associated with experience of harm from coworkers' drinking.

In an online survey, Norwegian employees (

 = 3596) aged 20-69 reported whether they had experienced the following due to coworkers' drinking the past 12 months (a) felt excluded, (b) experienced unwanted sexual attention, (c) been physically harmed, and (d) been verbally abused. Each outcome was regressed on socio-demographics (age, gender, education, and income), job characteristics (flexibility and autonomy), respondents' alcohol use, and perceived intoxication frequency in work contexts for a typical coworker (perceived coworker intoxication frequency).

The 12-month prevalence of experiencing any of the negative consequences was 18%. Having felt excluded (10.7%) and experencing unwanted sexual attention. Women experienced less physical harm and more unwanted sexual attention than men. Prevalence also varied by age, education, income, and job characteristics. Conclusions Each year, approximately one-sixth of Norwegian employees experience harm from their coworkers' drinking. The frequency of intoxication in work contexts is strongly associated with harm to others.Ferroptosis is an iron-dependent, non-apoptotic form of regulated cell death caused by lipid peroxidation, which is controlled by integrated oxidation and antioxidant systems. The iron-containing enzyme lipoxygenase is the main promoter of ferroptosis by producing lipid hydroperoxides, and its function relies on the activation of ACSL4-dependent lipid biosynthesis. In contrast, the selenium-containing enzyme GPX4 is currently recognized as a central repressor of ferroptosis, and its activity depends on glutathione produced from the activation of the cystine-glutamate antiporter SLC7A11. Many metabolic (especially involving iron, lipids, and amino acids) and degradation pathways (macroautophagy/autophagy and the ubiquitin-proteasome system) orchestrate the complex ferroptotic response through direct or indirect regulation of iron accumulation or lipid peroxidation. Although the detailed mechanism of membrane injury during ferroptosis remains a mystery, ESCRT III-mediated plasma membrane repair can make cells resistant to ferroptosis.
