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.

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.

Introduction: The dynamism in the regulatory frameworks concerning the consumption of cannabinoids has placed their effects on the 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 skill, 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 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.
