Abstract
ABSTRACT INTRODUCTION: Nurses have a central role in educating patients and families about treatment options and how to integrate them into action plans for neurologic conditions. In recent years, a growing number of intranasal formulations have become available as rescue therapy for neurologic conditions or symptoms including migraine, opioid overdose, and seizures. Rescue therapies do not replace maintenance medications or emergency care but are designed to enable rapid treatment of urgent or disabling conditions in community settings. Yet, discussion of rescue therapies for neurologic conditions remains limited in nursing literature. CONTENT: Intranasal formulations are specifically formulated for delivery and absorption in the nose and have several characteristics that are well suited as rescue therapies for neurologic conditions. Intranasal formulations include triptans for migraine, naloxone and nalmefene for opioid overdose, and benzodiazepines for seizure clusters in patients with epilepsy. Therapeutic attributes discussed here include ease of use in community settings by nonmedical professionals, relatively rapid onset of action, and favorable safety profile and patient experience. This information is critical for nurses to make informed decisions about rescue therapy options, incorporate these into plans of care, and educate patients, care partners, and other healthcare providers. CONCLUSION: Rescue therapies are increasingly important in the care of people with neurologic conditions. Various formulations are available and continue to evolve, offering easy and quick ways for nurses, patients, and nonmedical care partners to administer critical rescue medications. For nurses overseeing medication management, the attributes of intranasal rescue therapies should be considered in the context of providing patients with the right care at the right time.

Abstract
BACKGROUND Pulmonary infections are an increasing problem in individuals and current therapies are lacking. Liposomes are spherical lipidic vesicles composed of phospholipid and cholesterol. Liposomes have numerous advantages, such as biodegradability, biocompatibility, non-immunogenicity, lack of toxicity, controlled release properties and high stability. OBJECTIVE This work was carried out to construct a novel liposomal moxifloxacin formulation and examine its antimicrobial effects against Pseudomonas aeruginosa and Staphylococcus aureus. METHODS The liposomal moxifloxacin formulation was prepared by the thin-film hydration method. The bilayer was composed of cholesterol and phospholipid at 30:70 molar ratio. To prepare cationic liposomes, 5% cationic agent (CTAB) was added. The liposomes were reduced in size with the bath sonication technique. The liposomal characterizations were tested regarding vesicle size, surface charge and drug encapsulation efficacy. Microdilution method was used to determine the Minimum Inhibitory Concentration (MIC) against Pseudomonas aeruginosa and Staphylococcus aureus of the free drug, neutral and cationic moxifloxacin liposomes. RESULTS The size of the liposomes was 50-70 nm. The zeta potential of neutral and cationic vesicles was ∼0 and +22 mV. The MIC values against Pseudomonas aeruginosa of the free drug, neutral and cationic moxifloxacin liposomes were 10, 5 and 2.5, respectively. The MICs against Staphylococcus aureus of the free drug, neutral and cationic moxifloxacin liposomes were 1, 1 and 0.5, respectively. CONCLUSION This study demonstrates that the encapsulation of moxifloxacin into liposomes (especially cationic vesicles) could enhance antimicrobial properties.

Abstract
Nanoemulsions (NEs) or nanometric-scaled emulsions are transparent or translucent, optically isotropic and kinetically stable heterogeneous system of two different immiscible liquids namely, water and oil stabilized with an amphiphilic surfactant having droplet size ranges up to 100 nm. They offer a variety of potential interests for certain applications: improved deep-rooted stability; excellent optical clarity; and, enhanced bioavailability due to its nanoscale of particles. Though there is still comparatively narrow insight apropos design, development, and optimization of NEs, which mainly stems from the fact that conventional characteristics of emulsion development and stabilization only partly apply to NEs. The contemporary article focuses on the nanoemulsion dosage form journey from concept to key application in drug delivery. In addition, industrial scalability of the nanoemulsion, as well as its presence in commercial and clinical practice, are also addressed.

Abstract
Nanotechnology, particularly nanoemulsions (NEs), have gained increasing interest from researchers throughout the years. The small-sized droplet with a high surface area makes NEs important in many industries. In this review article, the components, properties, formation, and applications are summarized. The advantages and disadvantages are also described in this article. The formation of the nanosized emulsion can be divided into two types: high and low energy methods. In high energy methods, high-pressure homogenization, microfluidization, and ultrasonic emulsification are described thoroughly. Spontaneous emulsification, phase inversion temperature (PIT), phase inversion composition (PIC), and the less known D-phase emulsification (DPE) methods are emphasized in low energy methods. The applications of NEs are described in three main areas which are food, cosmetics, and drug delivery.

Abstract
Poor medication adherence is a pervasive problem that causes disability and suffering as well as extensive financial costs among individuals with bipolar disorder (BD). Barriers to adherence are numerous and cross multiple levels, including factors related to bipolar pathology and those unique to an individual's circumstances. External factors, including treatment setting, healthcare system, and broader health policies, can also affect medication adherence in people with BD. Fortunately, advances in research have suggested avenues for improving adherence. A comprehensive review of adherence-enhancement interventions for the years 2005-2015 is included. Specific bipolar adherence-enhancement approaches that target knowledge gaps, cognitive patterns, specific barriers, and motivation may be helpful, as may approaches that capitalize on technology or novel drug-delivery systems. However, much work remains to optimally facilitate long-term medication adherence in people with BD. For adherence-enhancement approaches to be widely adapted, they need to be easily accessible, affordable, and practical.

Abstract
During the last few decades, a fair amount of scientific investigation has focused on developing novel and efficient drug delivery systems. According to different clinical needs, specific biopharmaceutical carriers have been proposed. Micro- and nanoparticulated systems, membranes and films, gels and even microelectronic chips have been successfully applied in order to deliver biopharmaceuticals via different anatomical routes. The ultimate goal is to deliver the potential drugs to target tissues, where regeneration or therapies (chemotherapy, antibiotics, and analgesics) are needed. Thereby, the bioactive molecule should be protected against environmental degradation. Delivery should be achieved in a dose- and time-correct manner. Drug delivery systems (DDS) have been conceived to provide improvements in drug administration such as ability to enhance the stability, absorption and therapeutic concentration of the molecules in combination with a long-term and controlled release of the drug. Moreover, the adverse effects related with some drugs can be reduced, and patient compliance could be improved. Recent advances in biotechnology, pharmaceutical sciences, molecular biology, polymer chemistry and nanotechnology are now opening up exciting possibilities in the field of DDS. However, it is also recognized that there are several key obstacles to overcome in bringing such approaches into routine clinical use. This review describes the present state-of-the-art DDS, with examples of current clinical applications, and the promises and challenges for the future in this innovative field.
