Development of an online discrete choice experiment to elicit preferences for tobacco treatment among college students.

OBJECTIVE: To develop an online discrete choice experiment (DCE) to elicit preferences for the format and content of tobacco treatment and determine the feasibility of the survey in face-to-face online interviews among college students. PARTICIPANTS: A convenience sample of 28 college students. METHODS: A pilot online DCE survey with sixteen choice sets was developed. The feasibility was assessed by: 1) ease of reading the survey descriptions, 2) ease of completing the DCE survey, and 3) appropriateness of the number of choice sets. Think-aloud data were analyzed to understand decision-making processes. RESULTS: All participants completed the DCE survey and reported that it was very easy to read and complete and that the number of sixteen choice sets was appropriate. Such results support the feasibility of our online DCE survey. Five decision-making strategies were identified. CONCLUSIONS: An online DCE survey administered during online interviews may replace in-person interviews for college students.

Cannabis and Driving: Developing Guidelines for Safety Policies.

INTRODUCTION: The dynamism in the regulatory frameworks concerning the consumption of cannabinoids has placed their effects on cognitive and psychomotor skills at the center of the scientific debate. In consideration of the potential repercussions on public safety, particular attention has been focused on the impairment of driving skills, opening up the need to specifically regulate driving under the effects of cannabinoids. PHARMACOKINETICS: Both native cannabinoids and metabolites show a long positivity at low concentrations in the biological fluids, especially in the case of chronic consumption. Qualitative positivity to cannabinoids does not itself prove the presence of detrimental effects, which require the presence of active substances at relevant concentrations. Driving Skill Impairment: Multiple studies highlight a tetrahydrocannabinol (THC) concentration- based alteration of driving skills mainly affecting automatisms, whereas skills subjected to cognitive control are preserved up to higher dosages. The evidence relating to associations with other substances, chronic consumption and other cannabinoids, on the other hand, is still burdened by a high degree of uncertainty. Regulation Policies: Different models can be adopted in the regulation of driving under the effects of cannabinoids: sanctions can be applied in case of qualitative positivity, cannabinoids concentration above a defined threshold, or in presence of a demonstrated state of cognitive alteration. CONCLUSION: "Per se limit" with a quantitative THC cut-off between 3.5 and 5 ng/ml can currently be considered the most balanced choice. Finally, the analysis carried out allowed to identify pitfalls in both scientific and legislative fields for the improvement of safety policies.

Exploring the Application of Interpretive Description in Chronic Illness: A Scoping Review.

BACKGROUND AND PURPOSE: Chronic illness is a complex condition that affects over one billion people. To develop a deeper insight of the needs of this patient population, interpretive description uses disciplinary knowledge as the source of understanding. This methodology is a pragmatic approach to research without focusing on a strict methodological directive. The aims of this scoping review are twofold, (a) to describe the findings of studies that have used Thorne's interpretive description to research chronic illness and (b) to discuss the application of interpretive description in clinical research. Thereby, showing interpretive description as a valuable tool to advance nursing knowledge and patient care. METHODS: The methodological framework for this review was based on the Johanna Briggs Institute guidelines for scoping reviews. RESULTS: To develop an understanding of interpretive description, it is essential to examine the results of studies which have applied the methodology. Our scoping review showed that researchers utilizing interpretive description identified four common challenges experienced by individuals living with chronic illness: symptom management, education and knowledge, supportive care, and cultural disadvantages. By demonstrating how interpretive description is applied, it shows how it can be used to understand and interpret clinical phenomena to improve practice. IMPLICATION FOR PRACTICE: This scoping review demonstrates how interpretive description was used to develop knowledge about chronic illness. The premise of interpretive description is that disciplinary knowledge offers a sufficient foundation to develop meaningful research to support health practices. By approaching research from a disciplinary perspective, new knowledge can be discovered to complex health problems.

Obstacles to preventive care for individuals with disability: Implications for nurse practitioners.

BACKGROUND AND PURPOSE: Individuals with disabilities have been identified as a population with a significantly lower usage of preventive services. Nurse practitioners (NPs) provide a key access point in the healthcare delivery system for preventive services for vulnerable populations such as those with disabilities. It is essential to understand existing barriers that prohibit access to effective preventive care for this vulnerable population. METHODS: Systematic search and review of Cumulative Index of Nursing and Allied Health Literature (CINAHL), Medline, PubMed, Google Scholar, and government reports and World Health Organizations reports. Twenty-six articles were included in the review. CONCLUSIONS: This literature review confirmed previous notions that people with disabilities are receiving much fewer preventive services than the general population. The studies reviewed identified four major barriers that contributed to the lack of preventive care. These barriers included physical environment and system, transportation, provider knowledge and attitude, and financial. Recognition of the obstacles that this subpopulation faces in accessing preventive care services is the first step to effectively remedying this problem. IMPLICATIONS FOR PRACTICE: Preventive services have been identified as one of the cornerstones to improving health and quality of life. By understanding the circumstances that restrict those with disabilities from accessing preventive services, NPs can provide meaningful and effective solutions.

Magnesium sulfate therapy after aneurysmal subarachnoid hemorrhage.

OBJECT: Vasospasm remains a significant source of neurological morbidity and mortality following aneurysmal subarachnoid hemorrhage (SAH), despite advances in current medical, surgical, and endovascular therapies. Magnesium sulfate therapy has been demonstrated to be both safe and effective in preventing neurological complications in obstetrical patients with eclampsia. Evidence obtained using experimental models of brain injury, cerebral ischemia, and SAH indicate that Mg may also have a role as a neuroprotective agent. The authors hypothesize that MgSO4 therapy is safe, feasible, and has a beneficial effect on vasospasm and, ultimately, on neurological outcome following aneurysmal SAH. METHODS: A prospective randomized single-blind clinical trial of high-dose MgSO4 therapy following aneurysmal SAH (Hunt and Hess Grades II-IV) was performed in 40 patients, who were enrolled within 72 hours following SAH and given intravenous MgSO4 or control solution for 10 days. Serum Mg++ levels were maintained in the 4 to 5.5 mg/dl range throughout the treatment period. Clinical management principles were the same between groups (including early use of surgery or endovascular treatment, followed by aggressive vasospasm prophylaxis and treatment). Daily transcranial Doppler (TCD) ultrasonographic recordings were obtained, and clinical outcomes were measured using the Glasgow Outcome Scale (GOS). The patients' GOS scores and the TCD recordings were analyzed using the independent t-test. Forty patients were enrolled in the study: 20 (15 female and five male patients) received treatment and 20 (11 female and nine male patients) comprised a control group. The mean ages of the patients in these groups were 46 and 51, respectively, and the mean clinical Hunt and Hess grades were 2.6 +/- 0.68 in the MgSO4 treatment group and 2.3 +/- 0.73 in the control group (mean +/- standard deviation [SD], p = 0.87). Fisher grades were similar in both groups. Mean middle cerebral artery velocities were 93 +/- 27 cm/second in MgSO4-treated patients and 102 +/- 34 cm/second in the control group (mean +/- SD, p = 0.41). Symptomatic vasospasm, confirmed by angiography, occurred in six of 20 patients receiving MgSO4 and in five of 16 patients receiving placebo. Mean GOS scores were 3.8 +/- 1.6 and 3.6 +/- 1.5 (mean +/- SD, p = 0.74) in the treatment and control groups, respectively. Significant adverse effects from treatment with MgSO4 did not occur. CONCLUSIONS: Administration of high-dose MgSO4 following aneurysmal SAH is safe, and steady Mg++ levels in the range of 4 to 5.5 mg/dl are easily maintained. This treatment does not interfere with neurological assessment, administration of anesthesia during surgery, or other aspects of clinical care. We observed a trend in which a higher percentage of patients obtained GOS scores of 4 or 5 in the group treated with MgSO4, but the trend did not reach a statistically significant level. A larger study is needed to evaluate this trend further.
