TL;DR: Comparing the ability of five systemically administered selective serotonin uptake inhibitors to increase acutely the extracellular concentrations of serotonin, norepinephrine and dopamine in rat prefrontal cortex suggests that fluoxetine is an atypical SSRI.
Abstract: Rationale: The selective serotonin uptake inhibitor (SSRI) fluoxetine has been shown to not only increase the extracellular concentrations of serotonin, but also dopamine and norepinephrine extracellular concentrations in rat prefrontal cortex. The effect of other SSRIs on monoamine concentrations in prefrontal cortex has not been thoroughly studied. Objective: The aim of this study was to compare the ability of five systemically administered selective serotonin uptake inhibitors to increase acutely the extracellular concentrations of serotonin, norepinephrine and dopamine in rat prefrontal cortex. Methods: The extracellular concentrations of monoamines were determined in the prefrontal cortex of conscious rats using the microdialysis technique. Results: Fluoxetine, citalopram, fluvoxamine, paroxetine and sertraline similarly increased the extracellular concentrations of serotonin from 2- to 4-fold above baseline. However, only fluoxetine produced robust and sustained increases in extracellular concentrations of norepinephrine and dopamine after acute systemic administration. Fluoxetine at the same dose blocked ex vivo binding to the serotonin transporter, but not the norepinephrine transporter, suggesting that the increase of catecholamines was not due to non-selective blockade of norepinephrine uptake. Prefrontal cortex extracellular concentrations of fluoxetine at the dose that increased extracellular monoamines were 242 nM, a concentration sufficient to block 5-HT2C receptors which is a potential mechanism for the fluoxetine-induced increase in catecholamines. Conclusion: Amongst the SSRIs examined, only fluoxetine acutely increases extracellular concentrations of norepinephrine and dopamine as well as serotonin in prefrontal cortex, suggesting that fluoxetine is an atypical SSRI.

TL;DR: Among critically ill patients and their surrogates, a family‐support intervention delivered by the interprofessional ICU team did not significantly affect the surrogate's burden of psychological symptoms, but the surrogates' ratings of the quality of communication and the patient‐ and family‐centeredness of care were better and the length of stay in the ICU was shorter with the intervention than with usual care.
Abstract: Background Surrogate decision makers for incapacitated, critically ill patients often struggle with decisions related to goals of care. Such decisions cause psychological distress in surrogates and may lead to treatment that does not align with patients’ preferences. Methods We conducted a stepped-wedge, cluster-randomized trial involving patients with a high risk of death and their surrogates in five intensive care units (ICUs) to compare a multicomponent family-support intervention delivered by the interprofessional ICU team with usual care. The primary outcome was the surrogates’ mean score on the Hospital Anxiety and Depression Scale (HADS) at 6 months (scores range from 0 to 42, with higher scores indicating worse symptoms). Prespecified secondary outcomes were the surrogates’ mean scores on the Impact of Event Scale (IES; scores range from 0 to 88, with higher scores indicating worse symptoms), the Quality of Communication (QOC) scale (scores range from 0 to 100, with higher scores indicati...

TL;DR: The results suggest that the addition of a PCSK9 inhibitor to statin therapy may result in even further LDL-C decreases, which are currently seen in patients treated with atorvastatin.

TL;DR: DFdC-induced inhibition of dCMP deaminase resulted in a decrease of dFdCTP catabolism, contributing to the concentration-dependent elimination kinetics.
Abstract: 2',2'-Difluorodeoxycytidine (dFdC, Gemcitabine) is a deoxycytidine analogue which, after phosphorylation to the 5'-di- and 5'-triphosphate (dFdCTP), induces inhibition of DNA synthesis and cell death. We examined the values for elimination kinetics of cellular dFdCTP and found they were dependent on cellular concentration after incubation of CCRF-CEM cells with dFdC and washing into drug-free medium. When the drug was washed out at low cellular dFdCTP levels (less than 50 microM), dFdCTP elimination was linear (t1/2 = 3.3 h), but it became biphasic at intracellular dFdCTP levels greater than 100 microM. Although the initial elimination rate was similar at all concentrations, at higher concentrations the terminal elimination rate increased with increasing cellular dFdCTP concentration, with a nearly complete inhibition of dFdCTP elimination at 300 microM. The deamination product 2',2'-difluorodeoxyuridine was the predominant extracellular catabolite at low cellular dFdCTP concentrations, whereas at high dFdCTP concentrations dFdC was the major excretion product. The dCMP deaminase inhibitor 3,4,5,6-tetrahydrodeoxyuridine transformed the monophasic dFdCTP degradation seen at low dFdCTP levels into a biphasic process, whereas the deoxycytidine deaminase inhibitor 3,4,5,6-tetrahydrouridine had no effect on dFdCTP elimination. An in situ assay indicated that dCMP deaminase activity was inhibited in whole cells, an action that was associated with a decreased dCTP:dTTP value. In addition, dFdCTP inhibited partially purified dCMP deaminase with a 50% inhibitory concentration of 0.46 mM. We conclude that dFdC-induced inhibition of dCMP deaminase resulted in a decrease of dFdCTP catabolism, contributing to the concentration-dependent elimination kinetics. This action constitutes a self-potentiation of dFdC activity.

TL;DR: A new benzothiophene derived antiestrogen, LY139481, inhibited the uterotropic action of Estradiol in a dose related fashion, and at 1 mg per day suppressed more than 90 percent of estradiol's activity in immature rats.
