Sleep disturbances were common among the Taiwanese FCs of patients with advanced cancer. FCs with risk factors for sleep disturbances should be identified and provided assistance.
Numerous studies have shown that a variety of cytokines are involved in the regulation of ovarian function. Interleukin-6 (IL-6), has been found in follicular fluid. In this report we show by immunocytochemical methods the localization of the extracellular domain of the IL-6-receptor and its associated signal transducer glycoprotein gp 130 on the surface of granulosa cells (GCs). The possibility that IL-6 may also influence the basal and FSH-stimulated production of estradiol (E2) and progesterone (Prog) by GCs in vitro was also investigated.GCs were obtained from infertile patients undergoing in vitro fertilization and embryo transfer treatment and cultured for 72 h or were given increasing concentrations of human recombinant IL-6 (8-128 pg/ml) in the absence or presence of FSH (96 U/ml). For the time-course studies, FSH-stimulated GCs were treated in the absence or presence of IL-6 (128 pg/ml) and supernatants were assayed at 24 h intervals (24-96 h) for E2 and Prog productions. The results show that increasing amounts of IL-6 significantly inhibit E2 production in the absence or presence of FSH vs untreated controls (P=0·025 at IL-6=128 pg/ml and P=0·016 at IL-6=16 pg/ml respectively). IL-6 also inhibited FSH-stimulated but not unstimulated Prog release (P=0·038 at IL-6=8 pg/ml). These findings suggest that IL-6 may be one of the factors that plays a local regulatory role in the course of FSHstimulated E2 and Prog release. The time-course studies of the effect of the absence or presence of IL-6 demonstrated a significant inhibitory effect on both E2 and Prog secretion (P<0·001) by FSH-stimulated GCs. As infections of the female reproductive tract are often accompanied by elevated local IL-6 levels, this factor may be one of the links leading to endocrine reproductive dysfunction during genital infections.
Ventilator-associated pneumonia (VAP) is a subset of hospital-acquired pneumonias and is a serious, sometimes fatal, complication in patients who need mechanical ventilation. In addition, pay-for-performance initiative has placed increased emphasis on preventing nosocomial infections including VAP. Facilities may not be reimbursed for costs associated with prevalence infections. This article presents a review and meta-analysis of the prevention of VAP through the aspiration of subglottic secretion.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
