OBJECTIVE To determine the association of postpartum contraceptive use with repeat deliveries among adolescents and youth. DESIGN Retrospective, observational analysis of electronic health record data. SETTING Single, urban facility in Denver, Colorado, USA. POPULATION Women aged 10 - 24 who gave birth between January 1, 2011 and December 31, 2015. OUTCOME MEASURES Postpartum contraceptive use and time to subsequent delivery. RESULTS Among 4,068 women, 1,735 (43%) used postpartum contraception. In adjusted analyses, characteristics associated with contraceptive use included Hispanic ethnicity (RR 1.1, p = 0.03), incremental prenatal visits (RR 1.01, p = 0.047), and attendance at postpartum care (RR 1.60, p less then 0.001). Long-acting reversible contraceptive (LARC) use was higher among women less than 15 years (ref 20 - 24 years, RR 1.12, p less then 0.001) and lower among women aged 18 - 19 years (RR 0.93, p = 0.009). Hispanic women had higher LARC use than non-Hispanic women (RR 1.07, p = 0.02). Compared to inpatient LARC placement, outpatient placement (1 - 4 weeks and 5 or more weeks) rates were lower (RR 0.77 and RR 0.89, respectively, p less then 0.001). Time to subsequent delivery was shorter in non-LARC users (median 659 days) and non-contraception users (median 624 days) as compared to LARC users (median 790 days, p less then 0.001); non-LARC postpartum contraceptive use did not significantly alter time to repeat delivery compared to women who used no method (p = 0.24). CONCLUSION Postpartum LARC use reduced the risk of repeat pregnancy with significant increase in time to the next delivery. Non-LARC use was no different from no contraceptive use in terms of time to repeat delivery. BACKGROUND Aromatase inhibitors (AIs) are utilized for estrogen-modulated conditions. Some borderline ovarian tumors (BOT) express estrogen receptors. We present two cases of progression from mucinous cystadenoma to mucinous BOT (mBOT) after prior cystectomies in whom an AI was used with recurrence prevention. CASE Two patients underwent laparoscopic ovarian cystectomy for mucinous cystadenoma. Serial imaging demonstrated recurrent ovarian cysts for which both underwent fertility sparing surgery (FSS) with ovarian cystectomy for mBOT. Both patients were initiated on an AI and have been without recurrence. SUMMARY AND CONCLUSION BOT predominantly occur in reproductive aged females. FSS with cystectomy is an option, but recurrence occurs in 12-36% of cases. The use of AI in prevention of recurrent BOT shows promise, and more studies are needed to explore this treatment. In humans, Salmonella enterica infections are responsible for a plethora of medical conditions. These include intestinal inflammation and typhoid fever. The initial contact between Salmonella and polarized epithelial cells is established by the SPI4-encoded type I secretion system (T1SS), which secretes SiiE, a giant non-fimbrial adhesin. We have recombinantly produced various domains of this T1SS from Salmonella enterica serovar Typhimurium in Escherichia coli for further experimental characterization. Selleckchem Triapine We purified three variants of SiiD, the periplasmic adapter protein spanning the space between the inner and outer membrane, two variants of the SiiE N-terminal region and the N-terminal domain of the SiiF ATP-binding cassette (ABC) transporter. In all three proteins, at least one variant yielded high amounts of pure soluble protein. Secondary structure content and cooperative unfolding were investigated by circular dichroism (CD) spectroscopy. Secondary structure contents were in good agreement with estimates derived from SiiD and SiiF homology models or, in case of the SiiE N-terminal region, a secondary structure prediction. For one SiiD variant, protein crystals could be obtained that diffracted X-rays to approximately 4 Å resolution. Fear acquisition and generalization play key roles in promoting the survival of mammals and contribute to anxiety disorders. While previous research has provided much evidence for the repercussions of social exclusion on mental health, how social exclusion affects fear acquisition and generalization has received scant attention. In our study, participants were divided into two groups according to two Cyberball paradigm conditions (exclusion/inclusion). Both groups underwent a Pavlovian conditioning paradigm, functional near-infrared spectroscopy (fNIRS), and skin conductance response (SCR) assessments. We aimed to determine the effects of social exclusion on fear acquisition and generalization and whether modulation of the medial prefrontal cortex (mPFC) mediates this relationship. Our results showed that socially excluded participants featured significantly higher and lower shock risk scores to safety stimuli (conditioned stimulus, CS-) and threatening stimuli (CS+), respectively, than did socially included subjects during fear acquisition. The exclusion group had increased skin conductance responses (SCRs) to CS and exhibited heightened shock risk and increased SCRs to generalized stimuli compared with the inclusion group. The fNIRS results demonstrated that the CS + evoked larger oxy-Hb changes in the mPFC in the inclusion group than in the exclusion group during fear acquisition. Furthermore, the oxy-Hb of left mPFC of CS + mediated the effect on the association between social exclusion and perceived risk of CS+ in the fear acquisition. Our results indicate that social exclusion impairs fear acquisition and generalization via the mediation of the mPFC and that social exclusion increases susceptibility to anxiety disorders through bias processing of fear discrimination in fear acquisition and generalization. By studying the role of social relationship in fear acquisition and generalization, our research provides new insights into the pathological mechanisms of anxiety disorder. There is major concern regarding the pharmacokinetics of drugs under continuous renal replacement therapy (CRRT), including anti-infectious agents and more especially antifungal agents. From a regulatory viewpoint, only dialysis and filtration are considered meanwhile there is growing evidence that adsorption may also significantly alter the pharmacokinetics of anti-infectious agents. Adsorption results from a complex drug-filter interaction and might be considered an unexpected adverse effect induced by CRRT. Measurement of total plasma concentrations instead of the unbound, free, active concentrations in in vitro as well as in clinical studies hides this major adverse effect, which may jeopardise the therapeutic effect and even result in treatment failure. Noteworthy, minimal inhibitory concentrations (MIC) of anti-infectious agents are performed using solid and liquid medium without proteins testing only the antimicrobial activity of the free fraction of drugs. In a new in vitro model using crystalloid solution instead of blood, we report data supporting the assumption that the assessment of the disposition of the free fraction of caspofungin and micafungin unveils adverse effects of ST150® filter, which might eventually result in non-detectable drug concentrations and treatment failure.
