Perioperative nurses work in a complex health care setting and are well-positioned to mitigate unexpected events and promote optimal patient outcomes. Thus, perioperative nurses must adapt to rapid advances in technology, treatments, and scientific discoveries to maintain clinical competence and provide care that reflects current evidence. Evidence-based practice (EBP) is a standard of professional nursing performance and an expectation of professional nursing practice. Because EBP is foundational to health care quality and safety, perioperative nurses must understand the concepts of EBP and have the capacity to apply evidence to their clinical practice. However, some perioperative nurses struggle with EBP concepts and find it difficult to access, appraise, and apply evidence. In this article, we describe the five-step EBP process and provide valuable insights into EBP for perioperative RNs.Perioperative personnel are at risk for sharps injuries when using devices with sharp points and edges and therefore are at risk for infection from exposure to blood and other potentially infectious body fluids. The Occupational Safety and Health Administration bloodborne pathogens standard is the regulatory document that health care employers must follow to protect personnel who are at risk for sharps injuries. The AORN „Guideline for sharps safety” provides guidance to perioperative personnel for identifying sharps hazards and implementing best practices to prevent injuries. This article discusses the guideline recommendations for developing and implementing work practice controls and administrative controls for handling sharps. A scenario describes an interdisciplinary team’s efforts to decrease specific sharps injuries and develop policies and procedures based on the identified risks and practice changes. Perioperative RNs should review the entire guideline for additional information when creating and updating policies and procedures for sharps safety.Surgical attire guidelines (SAGs) assist perioperative nurses with minimizing the risk of patients developing surgical site infections. However, some intraoperative team members fail to fully adhere to SAGs, which may put patients at risk. Because there is a lack of published literature on the reasons for intraoperative team members’ SAG nonadherence, I undertook a grounded theory study to explore the decision making of intraoperative team members related to the AORN SAG. The resulting model identifies the factors that affect decision making regarding SAG adherence, including personal identity needs, adherence anchoring activities, SAG awareness, direction from authority figures and organizations, guideline evidence strength, and resource availability. After weighing the influence of each factor, team members decide to what extent they will adhere to the SAG. The theory also provides guidance for enhancing adherence decisions.

Though most medical institutions calculate antimicrobial susceptibility and resistance rates of microbes isolated at their own facility as part of their efforts to promote the proper use of antibiotics, very few, if any, regularly monitor cross-resistance rates between antimicrobial agents. The authors have devised a tool in the form of a cross-resistance rate correlation diagram (CRR diagram) that allows easy identification of increases or decreases in, or changes in the pattern of, antimicrobial cross-resistance. The objective was to perform an analysis by CRR diagrams of the effect of relocation to a newly built facility on antimicrobial resistance and cross-resistance rates at a medical facility.

The Sakai City Medical Center relocated in July 2015 to a newly built facility located in a different primary medical care zone 3.5km away. Based on the drug susceptibility test data compiled at the Sakai City Medical Center, resistance and cross-resistance rates of Pseudomonas aeruginosa before and after theans, but they also contribute to the proper use of antibiotics and serve as a tool in the education of healthcare professionals and students about antibiotic resistance.

Including cross-resistance rates in the routine monitoring of resistance and susceptibility rates practiced by a medical institution can provide a comprehensive insight into the dynamics of bacterial flora in the facility. CRR diagrams, which allow visualization of the status and changes in cross-resistance, not only provide a new perspective for clinicians, but they also contribute to the proper use of antibiotics and serve as a tool in the education of healthcare professionals and students about antibiotic resistance.Understanding individual variation in fitness-related traits requires separating the environmental and genetic determinants. Telomeres are protective caps at the ends of chromosomes that are thought to be a biomarker of senescence as their length predicts mortality risk and reflect the physiological consequences of environmental conditions. The relative contribution of genetic and environmental factors to individual variation in telomere length is, however, unclear, yet important for understanding its evolutionary dynamics. In particular, the evidence for transgenerational effects, in terms of parental age at conception, on telomere length is mixed. Here, we investigate the heritability of telomere length, using the 'animal model’, and parental age at conception effects on offspring telomere length in a wild population of European badgers (Meles meles). Although we found no heritability of telomere length and low evolvability ( less then 0.001), our power to detect heritability was low and a repeatability of 2% across individual lifetimes provides a low upper limit to ordinary narrow-sense heritability. However, year (32%) and cohort (3%) explained greater proportions of the phenotypic variance in telomere length, excluding qPCR plate and row variances. There was no support for cross-sectional or within-individual parental age at conception effects on offspring telomere length. Our results indicate a lack of transgenerational effects through parental age at conception and a low potential for evolutionary change in telomere length in this population. Instead, we provide evidence that individual variation in telomere length is largely driven by environmental variation in this wild mammal.Schizophrenia is a severe psychiatric disorder with a strong hereditary component that affects approximately 1% of the world’s population. The disease is most likely caused by the altered expression of a number of genes that function at the level of biological pathways or gene networks. Transcription factors (TF) are indispensable regulators of gene expression. EGR3 is a TF associated with schizophrenia. In the current study, DNA microarray and ingenuity pathway analyses (IPA) demonstrated that EGR3 regulates Reelin signaling pathway in SH-SY5Y cells. ChIP and luciferase reporter studies confirmed that EGR3 directly binds to the promoter region of RELN thereby activating RELN expression. The expression of both EGR3 and RELN was decreased during neuronal differentiation induced by retinoic acid (RA) in SH-SY5Y cells, and EGR3 over-expression reduced neurite outgrowth which could be partially reversed by the knockdown of RELN. The expression levels of EGR3 and RELN in peripheral blood of subjects with schizophrenia were found to be down-regulated (compared with healthy controls), and were positively correlated. Furthermore, data mining from public databases revealed that the expression levels of EGR3 and RELN were presented a positive correlation in post-mortem brain tissue of subjects with schizophrenia. Taken together, this study suggests that EGR3 is a novel TF of the RELN gene and regulates neurite outgrowth via the Reelin signaling pathway. Our findings contribute to the understanding of the regulatory role of EGR3 in the pathophysiology and molecular mechanisms of schizophrenia, and potentially to the development of new therapies and diagnostic biomarkers for the disorder.

To examine the association of gestational weight gain (GWG), categorized according to 2009 IOM guidelines as adequate, inadequate, and excessive, with symptoms of mental disorders perceived by mothers after childbearing as anhedonia, anxiety, and depression, defined by the Edinburgh Postnatal Depression Scale (EPDS). Previous studies indicated that disorders related to GWG are associated with an increased risk of postpartum psychological distress.

A prospective cohort study took place at the Policlinico Abano Terme, Italy, from May 2016 to November 2018.

The sample included 1268 healthy at term puerperae, 557 (43.9%) with adequate, 388 (30.6%) with inadequate, and 323 (25.5%) with excessive GWG. Mean EPDS scores were comparable among inadequate, adequate, and excessive GWG groups. However, mean factor scores for anhedonia and anxiety were significantly higher (P=0.041 and P=0.001, ANOVA) in mothers with excessive GWG. Conversely, factor scores for depression were significantly higher (P=0.008, ANOVA) in mothers with inadequate GWG.

It was found that excessive GWG across an uncomplicated pregnancy is a warning sign of symptoms of anhedonia and anxiety, whereas inadequate GWG is a significant indicator of symptoms of depression. These relationships highlight the potential for interventions directed toward psychosocial support to have beneficial effects upon GWG.

To assess the effectiveness of hyoscine-N-butylbromide on the duration of the first stage of labor among nulliparous women.

A randomized double-blind placebo-controlled study among 126 nulliparous women admitted in the active phase of labor to a teaching hospital in Sagamu, Nigeria, from January to August 2018. Based on the inclusion criteria, women were recruited and randomized to the study or control group, and given intravenous hyoscine-N-butylbromide 20mg (1mL) or sterile water (1mL), respectively, during the active phase. Labor progress and outcomes were compared between the groups.

The mean±SD duration of active phase of first stage of labor was significantly shorter in the hyoscine-N-butylbromide group (324.9±134.6min) than in the control group (392.7±119.6min) (P=0.004). The rate of cervical dilatation was 1.4±0.8cm/h in the hyoscine-N-butylbromide group and 1.0±0.5cm/h in the control group (P=0.004). There were no significant differences in fetal heart rate, maternal vital signs, or Apgar scores between the two groups.

Hyoscine-N-butylbromide was found to be effective in shortening the duration of the first stage of labor without adverse outcomes for mother or neonate. The trial was registered with the Pan African Clinical trials Registry (PACTR), protocol number PACTR201808146688942 (https//pactr.samrc.ac.za/TrialDisplay.aspx?TrialID=3532).
