question:
Context: To distinguish whether the improvement of hepatic encephalopathy by benzodiazepine receptor antagonists is mediated by their antagonistic or their inverse agonistic properties, the neurobehavioral effects of a variety of benzodiazepine receptor ligands in rats with thioacetamide-induced acute liver failure were tested.', 'The neural inhibitory effect of the benzodiazepine agonist flunitrazepam and its reversibility by the "pure" antagonist Ro 14-7437 were examined in thioacetamide-treated rats and controls. The effects of Ro 14-7437, of the partial inverse agonist Ro 15-4513, and the inverse agonist DMCM in rats with hepatic encephalopathy grade II/III were tested. Encephalopathic rats were pretreated with Ro 14-7437 or vehicle and then injected with Ro 15-4513.', 'Thioacetamide-treated rats were more sensitive to flunitrazepam than controls. In both groups, its effect was completely antagonized with Ro 14-7437. Encephalopathy was significantly improved by Ro 15-4513, although Ro 14-7437 and vehicle had no effect. DMCM worsened the condition of encephalopathic rats but had no effect in controls. Pretreatment with Ro 14-7437 abolished the beneficial effects of Ro 15-4513.
Answer: In rats with thioacetamide-induced liver failure, endogenous benzodiazepines do not precipitate hepatic encephalopathy. The amelioration of hepatic encephalopathy is mediated by benzodiazepine receptor ligands with both antagonistic and inverse agonistic properties.
answer:
Is hepatic encephalopathy in rats with thioacetamide-induced acute liver failure mediated by endogenous benzodiazepines?


question:
Context: The goals of the current study were to examine the incidence and severity of toxicity resulting from dexamethasone and prednisone during induction therapy for children with precursor B-cell acute lymphoblastic leukemia (ALL) and to determine whether the addition of daunomycin affected toxicity.', 'Medical records of patients with precursor B-cell ALL from January 1996 through June 2000 were reviewed retrospectively for toxicity during the 4-week induction phase and the 2 weeks after the induction phase.', 'One hundred seventy-six patients age < 14 years were diagnosed with precursor B-cell ALL from January 1996 through June 2000. Of the 156 evaluable patients, 106 were treated with prednisone and 50 with dexamethasone. Fifty-two patients received steroids, L-asparaginase, and vincristine, whereas 104 high-risk patients received daunomycin in addition to these 3 agents. The incidence of gastritis was significantly higher among patients receiving dexamethasone (P = 0.01); incidence rates of hyperglycemia, hypertension, and myopathy were similar for all treatment groups. Dexamethasone led to more weight gain than did prednisone (+11.9% vs. +5.4%; P = 0.002). Serious infections were observed in 27 (25.5%) and 18 (36%) patients receiving prednisone and dexamethasone, respectively (P < or = 0.2). Five patients, four of whom received prednisone and one of whom received dexamethasone, died of infection. The addition of daunomycin to treatment regimens increased overall toxicity (P < 0.01). When daunomycin was included in treatment regimens, toxicity was greater among patients receiving dexamethasone; in contrast, when daunomycin was not included, toxicity was equal for both treatment groups. Regardless of daunomycin use, there was no difference in the incidence of serious infection between the two groups. ALL treatment was not compromised by steroid-related toxicity in either group.
Answer: The addition of daunomycin led to a much larger increase in dexamethasone-related toxicity compared with the increase in prednisone-related toxicity. Although the use of daunomycin enhanced dexamethasone-related toxicity, this enhancement did not result in a higher mortality rate or the alteration of planned ALL therapy.
answer:
Is dexamethasone-associated toxicity during induction chemotherapy for childhood acute lymphoblastic leukemia augmented by concurrent use of daunomycin?


question:
Context: Total parenteral nutrition (TPN) is a cause of intestinal microbial dysbiosis and impaired gut barrier function. This may contribute to life-threatening parenteral nutrition-associated liver disease and sepsis in infants. We compared the effects of a lipid emulsion containing long-chain ω-3 polyunsaturated fatty acids (PUFAs; SMOFlipid) and a predominantly ω-6 PUFA emulsion (Intralipid) on microbial composition and host response at the mucosal surface.', 'Neonatal piglets were provided isocaloric, isonitrogenous TPN for 14 days versus sow-fed (SF) controls. Equivalent lipid doses (10 g/kg/d) were given of either SMOFlipid (ML; n = 10) or Intralipid (SO; n = 9). Ileal segments and mucosal scrapings were used to characterize microbial composition by 16S rRNA gene sequencing and quantitative gene expression of tight junction proteins, mucins, antimicrobial peptides, and inflammatory cytokines.', 'The microbial composition of TPN piglets differed from SF, while ML and SO differed from each other (analysis of molecular variance; P < .05); ML piglets were more similar to SF, as indicated by UniFrac distance (P < .05). SO piglets showed a specific and dramatic increase in Parabacteroides (P < .05), while ML showed an increase in Enterobacteriaceae (P < .05). Gene expression of mucin, claudin 1, β-defensin 2, and interleukin 8 were higher in TPN; overall increases were significantly less in ML versus SO (P < .05).
Answer: The formulation of parenteral lipid is associated with differences in the gut microbiota and host response of TPN-fed neonatal piglets. Inclusion of ω-3 long-chain PUFAs appears to improve host-microbial interactions at the mucosal surface, although mechanisms are yet to be defined.
answer:

Does lipid Emulsion Formulation of Parenteral Nutrition affect Intestinal Microbiota and Host Responses in Neonatal Piglets?
