Effect of dexamethasone administration for postoperative nausea and vomiting prophylaxis on glucose levels in adults with diabetes undergoing elective surgery: a systematic review with meta-analysis.

Objective: The objective of this review was to evaluate the effect of intravenous dexamethasone given intraoperatively for postoperative nausea and vomiting prophylaxis on maximal blood glucose level within the initial 24 hours following elective surgery for patients with diabetes.

Introduction: Postoperative nausea and vomiting is a prevalent adverse effect of anesthesia that leads to morbidity, increased health care costs, and unanticipated hospital admissions. Dexamethasone is an effective prophylactic agent that confers secondary analgesic and anti-inflammatory benefits.

Pharmacological interventions for reducing the incidence of myoclonus in patients receiving etomidate for induction of general anesthesia: an umbrella review.

Objective: The objective of this umbrella review was to examine various pharmacologic interventions for their potential to reduce etomidate-induced myoclonus. A secondary objective was to compare the relative effectiveness of those medications in reducing the incidence of myoclonus when etomidate is utilized for the induction of general anesthesia.

Introduction: Etomidate is the drug of choice when inducing general anesthesia in hemodynamically unstable patients.

Development and Validation of a Quantitative Grading Rubric for High-Fidelity Simulation Assessment.

High-fidelity simulation scenarios provide trainees the opportunity to demonstrate foundational anesthesia skills, complex prioritization, and decision making. One strategy used in trainee assessment is an objective structured clinical examination (OSCE). The purpose of this study was to design an OSCE with a reliable, quantitative grading rubric that could be used as part of a comprehensive assessment strategy to determine readiness for entry into clinical training for nurse anesthesia residents.

Safety and effectiveness of regional anesthesia compared with anesthetic techniques not using regional anesthesia on outcomes after free tissue flap surgery: a systematic review protocol.

Objective: This systematic review will aim to evaluate the evidence on the effectiveness of regional anesthesia, when compared with general anesthesia alone, on the outcomes of free flap surgeries.

Introduction: Free flap procedures involve complete separation of a flap of tissue from its native vascular bed, followed by reimplantation to a recipient site on the body. Optimal perfusion and successful neovascularization are crucial to survival of the grafted flap.

Thinking about the idea of consent in data science genomics: How 'informed' is it?

In this paper we argue that 'informed' consent in Big Data genomic biobanking is frequently less than optimally informative. This is due to the particular features of genomic biobanking research which render it ethically problematic. We discuss these features together with details of consent models aimed to address them.

Effectiveness of intravenous magnesium sulfate to attenuate hemodynamic changes in laparoscopic surgery: a systematic review and meta-analysis.

Objective: The purpose of this systematic review and meta-analysis was to determine the effectiveness of intravenous magnesium sulfate when used to attenuate hemodynamic fluctuations associated with the creation of pneumoperitoneum in adults undergoing laparoscopic surgery.

Introduction: Laparoscopic surgery has gained popularity as a result of improved patient outcomes postoperatively, but pneumoperitoneum alters the patient's physiology and hemodynamic profile during the intraoperative period. Magnesium sulfate is a nonopioid agent known for its ability to blunt the physiologic sympathetic response associated with exposure to noxious stimuli.

Intravenous magnesium sulfate to attenuate hemodynamic changes in laparoscopic surgery: a systematic review protocol.

Objective: The objective of this systematic review is to determine the efficacy of intravenous magnesium sulfate when used to attenuate hemodynamic fluctuations associated with the creation of pneumoperitoneum in adults undergoing laparoscopic surgery.

Introduction: Laparoscopic surgery has gained popularity as a result of improved patient outcomes postoperatively, but pneumoperitoneum alters the patient's physiology and hemodynamic profile during the intraoperative period. Magnesium sulfate is a non-opioid agent known for its ability to blunt the physiologic sympathetic response associated with exposure to noxious stimuli.

Evolution of metazoan morphological disparity.

The animal kingdom exhibits a great diversity of organismal form (i.e., disparity).

Anesthetic Implications of Obesity and Obstructive Sleep Apnea.

The incidence of morbid obesity has tripled within the past 25 years in developed countries, with the highest rate of growth noted among people with body mass index (BMI) greater than 50. The physiologic derangements that accompany obesity affect almost every organ system leading to a vast array of comorbid conditions including obstructive sleep apnea (OSA). This review focuses on the unique perioperative management considerations that the nurse anesthetist must address when caring for these patients as well as the impact of obesity and OSA on postoperative complications and mortality rates.

Nutrient enrichment alters storage and fluxes of detritus in a headwater stream ecosystem.

Responses of detrital pathways to nutrients may differ fundamentally from pathways involving living plants: basal carbon resources can potentially decrease rather than increase with nutrient enrichment. Despite the potential for nutrients to accelerate heterotrophic processes and fluxes of detritus, few studies have examined detritus-nutrient dynamics at whole-ecosystem scales. We quantified organic matter (OM) budgets over three consecutive years in two detritus-based Appalachian (U.

The role of theory-constitutive metaphor in nursing science.

The current view of theoretical statements in science is that they should be literal and precise; ambiguous and metaphorical statements are useful only as pre-theoretical, exegetical, and heuristic devices and as pedagogical tools. In this paper we argue that this view is mistaken. Literal, precise statements apply to those experiential phenomena which can be defined either conventionally by criterial attribution or by internal atomic constitution.

Nutrients stimulate leaf breakdown rates and detritivore biomass: bottom-up effects via heterotrophic pathways.

Most nutrient enrichment studies in aquatic systems have focused on autotrophic food webs in systems where primary producers dominate the resource base. We tested the heterotrophic response to long-term nutrient enrichment in a forested, headwater stream. Our study design consisted of 2 years of pretreatment data in a reference and treatment stream and 2 years of continuous nitrogen (N) + phosphorus addition to the treatment stream.

Symbolic interactionism in grounded theory studies: women surviving with HIV/AIDS in rural northern Thailand.

Although it is generally acknowledged that symbolic interactionism and grounded theory are connected, the precise nature of their connection remains implicit and unexplained. As a result, many grounded theory studies are undertaken without an explanatory framework. This in turn results in the description rather than the explanation of data determined.

The acquisition and exercise of nephrology nursing expertise: a grounded theory study.

Aims And Objectives: This purpose of this study was to describe the process of expertise acquisition in nephrology nursing practice.

Background: It has been recognized for a number of decades that experts, compared with other practitioners in a number of professions and occupations, are the most knowledgeable and effective, in terms of both the quantity and quality of output. Studies relating to expertise have been undertaken in a range of nursing contexts and specialties; to date, however, none have been undertaken which focus on nephrology nursing.

"Hanging in" with HIV/AIDS in the rural north of Thailand: a grounded theory study.

A study was undertaken in 1997 through 2000 in the rural north of Thailand to describe and theorize the HIV/AIDS experiences of wives and widows there. Participants confronted four causally interrelated problems in their struggle to survive with HIV/ AIDS: physical, economic, psychoemotional, and sociocultural, and they used two social processes to manage them: namely, "hiding out" and "hanging in" with HIV/AIDS. This report describes and discusses the second of these basic social processes through which wives and widows in the rural north of Thailand cope with their HIV/AIDS infection.

Producing the magnum opus: a metaphor for nephrology nursing expertise acquisition.

Aim: This paper elucidates the nature of metaphor and the conditions necessary to its use as an analytic device in qualitative research, and describes how the use of metaphor assisted in the analytic processes of a grounded theory study of nephrology nursing expertise.

Background: The use of metaphor is pervasive in everyday thought, language and action. It is an important means for the comprehension and management of everyday life, and makes challenging or problematic concepts easier to explain.

Buddhism, the status of women and the spread of HIV/AIDS in Thailand.

The common-sense construction of Buddhism is that of a general power for good; the less positive aspects of Buddhism's power, especially when reinforced by folklore and ancient superstition, is infrequently recognised. In this article we make explicit Buddhism's less positive power, particularly as it relates to the status of women and, by implication, its role in the human immunodeficiency (HIV)/acquired immune deficiency syndrome (AIDS) epidemic in Thailand. The Buddhist, folklore, and superstitious bases of Thai misogyny are explored, together with its expression in the differential gender roles of women and men.

The evaluation of a clinical development unit leadership preparation program by focus group interviews - part 2: negative aspects.

In Western Sydney, Australia, in 1996, the Area Health Service and the University of Western Sydney entered a strategic alliance to develop a nursing research culture in the health services. One of the strategies implemented to achieve this was the establishment of a network of research-receptive environments known as Clinical Development Units (CDUs). In terms of research receptivity, evidence at the time suggested that it could only be developed in units where the leadership style is democratic and participatory.

The evaluation of a clinical development unit leadership preparation program by focus group interviews - part I: positive aspects.

In 1996, in Western Sydney, Australia, the Area Health Service and the University of Western Sydney entered a strategic alliance to develop a nursing research culture in the health services. One of the strategies implemented to achieve this was the establishment of a network of research-receptive environments known as Clinical Development Units (CDUs). At the time, however, evidence suggested that research receptivity will only develop in units where the leadership style is permissive and participatory; evidence also suggested that the successful establishment of CDUs hinged critically on the effective management of CDU leadership stressors.
