[PMID: 37721786 PMCID: PMC10546260 DOI: 10.2196/47460] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/21/2023] [Revised: 07/18/2023] [Accepted: 08/08/2023] [Indexed: 09/19/2023] Open
Abstract
BACKGROUND Obstructive sleep apnea (OSA) is characterized by recurrent, intermittent partial or complete obstruction of the upper respiratory tract during sleep, which negatively affects the patient's daily quality of life (QoL). Middle-aged and older men who smoke and have obesity are most at risk. Even though the use of continuous positive airway pressure (CPAP) during sleep remains the gold standard treatment, various rehabilitation methods, such as exercise, respiratory therapy, myofunctional therapy, and nutritional lifestyle interventions, also appear to be effective. Moreover, it is increasingly recommended to use alternative or additional therapy options in combination with CPAP therapy. OBJECTIVE This study aims to evaluate if a comprehensive home-based, remotely supervised rehabilitation program (tele-RHB), in combination with standard therapy, can improve OSA severity by decreasing the apnea-hypopnea index (AHI); improve objective parameters of polysomnographic, spirometric, anthropometric, and body composition examinations; improve lipid profile, maximal mouth pressure, and functional capacity tests; and enhance the subjective perception of QoL, as well as daytime sleepiness in male participants with moderate to severe OSA. Our hypothesis is that a combination of the tele-RHB program and CPAP therapy will be more effective by improving OSA severity and the abovementioned parameters. METHODS This randomized controlled trial aims to recruit 50 male participants between the ages of 30 and 60 years with newly diagnosed moderate to severe OSA. Participants will be randomized 1:1, either to a 12-week tele-RHB program along with CPAP therapy or to CPAP therapy alone. After the completion of the intervention, the participants will be invited to complete a 1-year follow-up. The primary outcomes will be the polysomnographic value of AHI, Epworth Sleepiness Scale score, 36-Item Short Form Health Survey (SF-36) score, percentage of body fat, 6-minute walk test distance covered, as well as maximal inspiratory and expiratory mouth pressure values. Secondary outcomes will include polysomnographic values of oxygen desaturation index, supine AHI, total sleep time, average heart rate, mean oxygen saturation, and the percentage of time with oxygen saturation below 90%; anthropometric measurements of neck, waist, and hip circumference; BMI values; forced vital capacity; forced expiratory volume in 1 second; World Health Organization's tool to measure QoL (WHOQOL-BREF) score; and lipid profile values. RESULTS Study recruitment began on October 25, 2021, and the estimated study completion date is December 2024. Analyses will be performed to examine whether the combination of the tele-RHB program and CPAP therapy will be more effective in the reduction of OSA severity and improvement of QoL, body composition and circumferences, exercise tolerance, lipid profile, as well as respiratory muscle and lung function, compared to CPAP therapy alone. CONCLUSIONS The study will evaluate the effect of a comprehensive tele-RHB program on selected parameters mentioned above in male participants. The results of this intervention could help the further development of novel additional therapeutic home-based options for OSA.

J Perianesth Nurs 2023:S1089-9472(22)00515-9. [PMID: 36599790 DOI: 10.1016/j.jopan.2022.09.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/07/2022] [Revised: 09/07/2022] [Accepted: 09/09/2022] [Indexed: 01/03/2023]
Abstract
PURPOSE The purpose of this project was to improve the consistency of verbal and written discharge instructions for women of childbearing age (13-55 years) taking hormonal contraceptives who receive aprepitant perioperatively, to address the need to use a secondary form of birth control for 28 days, as well as to increase the knowledge and confidence of Registered Nurses when providing discharge instructions. DESIGN This quality improvement project used a pre/post design to evaluate two separate groups of patients and registered nurses. METHODS The patient sample consisted of 30 total women of childbearing age who received aprepitant during the perioperative period (15 pre and 15 post). The PACU nurse sample included 15 ambulatory surgery center nurses and 58 main hospital nurses for a combined sample of 73 PACU nurses. The PACU nurses were provided with educational in-service regarding information about aprepitant and its drug interactions. PACU nurses were additionally instructed to provide patient discharge instructions using both a written and verbal format. Patients were called postoperatively before and after both the written after visit summary (AVS) changes and the PACU nurse in-services, PACU nurses were evaluated on their knowledge, confidence, and frequency of discharge teaching before and after their educational in-service. The PACU nurses were surveyed 90 days after the intervention to assess their long-term knowledge retention. FINDINGS There was a significant increase in nurse knowledge about aprepitant from preimplementation to postimplementation (61.39% vs 81.95%, P < .001). Nursing knowledge showed a non-significant decline at 90-days postimplementation (81.95% vs 73.68%, P = .096) although remained significantly higher than preimplementation scores (73.68% vs 61.39%, P = .003). There was an overall 33.3% increase in the percentage of patients who were able to recall receiving aprepitant and the need to use a secondary form of birth control when comparing the preintervention group to the postintervention group (26.7% vs 60%, P = .123). CONCLUSIONS The findings suggest that providing a standardized presentation about aprepitant may improve the PACU nurses' ability to verbalize key information about aprepitant, including the need for patients to use a secondary form of birth control. This increase in nursing knowledge and confidence, along with improved written discharge instructions, may have led to improved patient comprehension of aprepitant discharge education. Additionally, there was an increase in the percentage of patients who were able to recall the need to use a secondary form birth control for 28 days, to reduce the likelihood of an unintentional pregnancy.

[PMID: 32629222 PMCID: PMC7318976 DOI: 10.1016/j.cmpb.2020.105627] [Citation(s) in RCA: 36] [Impact Index Per Article: 9.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/14/2020] [Accepted: 06/21/2020] [Indexed: 05/12/2023]
Abstract
BACKGROUND AND OBJECTIVE Human upper airway (HUA) has been widely investigated by many researchers covering various aspects, such as the effects of geometrical parameters on the pressure, velocity and airflow characteristics. Clinically significant obstruction can develop anywhere throughout the upper airway, leading to asphyxia and death; this is where recognition and treatment are essential and lifesaving. The availability of advanced computer, either hardware or software, and rapid development in numerical method have encouraged researchers to simulate the airflow characteristics and properties of HUA by using various patient conditions at different ranges of geometry and operating conditions. Computational fluid dynamics (CFD) has emerged as an efficient alternative tool to understand the airflow of HUA and in preparing patients to undergo surgery. The main objective of this article is to review the literature that deals with the CFD approach and modeling in analyzing HUA. METHODS This review article discusses the experimental and computational methods in the study of HUA. The discussion includes computational fluid dynamics approach and steps involved in the modeling used to investigate the flow characteristics of HUA. From inception to May 2020, databases of PubMed, Embase, Scopus, the Cochrane Library, BioMed Central, and Web of Science have been utilized to conduct a thorough investigation of the literature. There had been no language restrictions in publication and study design of the database searches. A total of 117 articles relevant to the topic under investigation were thoroughly and critically reviewed to give a clear information about the subject. The article summarizes the review in the form of method of studying the HUA, CFD approach in HUA, and the application of CFD for predicting HUA obstacle, including the type of CFD commercial software are used in this research area. RESULTS This review found that the human upper airway was well studied through the application of computational fluid dynamics, which had considerably enhanced the understanding of flow in HUA. In addition, it assisted in making strategic and reasonable decision regarding the adoption of treatment methods in clinical settings. The literature suggests that most studies were related to HUA simulation that considerably focused on the aspects of fluid dynamics. However, there is a literature gap in obtaining information on the effects of fluid-structure interaction (FSI). The application of FSI in HUA is still limited in the literature; as such, this could be a potential area for future researchers. Furthermore, majority of researchers present the findings of their work through the mechanism of airflow, such as that of velocity, pressure, and shear stress. This includes the use of Navier-Stokes equation via CFD to help visualize the actual mechanism of the airflow. The above-mentioned technique expresses the turbulent kinetic energy (TKE) in its result to demonstrate the real mechanism of the airflow. Apart from that, key result such as wall shear stress (WSS) can be revealed via turbulent kinetic energy (TKE) and turbulent energy dissipation (TED), where it can be suggestive of wall injury and collapsibility tissue to the HUA.

A review of fluid-structure interaction simulation for patients with sleep related breathing disorders with obstructive sleep. COMPUTER METHODS AND PROGRAMS IN BIOMEDICINE 2019; 180:105036. [PMID: 31430594 DOI: 10.1016/j.cmpb.2019.105036] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/02/2019] [Revised: 08/02/2019] [Accepted: 08/12/2019] [Indexed: 05/05/2023]
Abstract
Obstructive sleep apnea is one of the most common breathing disorders. Undiagnosed sleep apnea is a hidden health crisis to the patient and it could raise the risk of heart diseases, high blood pressure, depression and diabetes. The throat muscle (i.e., tongue and soft palate) relax narrows the airway and causes the blockage of the airway in breathing. To understand this phenomenon computational fluid dynamics method has emerged as a handy tool to conduct the modeling and analysis of airflow characteristics. The comprehensive fluid-structure interaction method provides the realistic visualization of the airflow and interaction with the throat muscle. Thus, this paper reviews the scientific work related to the fluid-structure interaction (FSI) for the evaluation of obstructive sleep apnea, using computational techniques. In total 102 articles were analyzed, each article was evaluated based on the elements related with fluid-structure interaction of sleep apnea via computational techniques. In this review, the significance of FSI for the evaluation of obstructive sleep apnea has been critically examined. Then the flow properties, boundary conditions and validation of the model are given due consideration to present a broad perspective of CFD being applied to study sleep apnea. Finally, the challenges of FSI simulation methods are also highlighted in this article.
