OBJECTIVE: The purpose of this study was to evaluate the initial learning experience and acute procedural success in adopting this procedure in an academic training center.
METHODS: A retrospective review of LBBAP procedures using the Biotronik Solia stylet-driven lead from June 2022 to December 2023 was performed. Procedural and fluoroscopy times with electrocardiographic and pacing parameters were evaluated to determine safety and acute procedural outcomes.
RESULTS: A total of 69 patients (mean age 75 ± 12 years; 60.9% male) underwent LBBAP implantation over 18 months for standard pacing indications by 10 implanters (including 7 fellows-in-training) without previous experience in LBBAP technique. Mean total procedural time was 74.1 ± 23.5 minutes, and mean fluoroscopy time for LBBAP lead insertion was 9.3 ± 5.4 minutes. Mean paced QRS duration was 115.2 ± 15.5 ms, and mean left ventricular activation time was 79.4 ± 14.5 ms. An rsR' pattern was achieved in 76.8%. LBBAP was successful in 78.3% (overall 43.5% single deployment; median 2 [interquartile range 1-3]) with excellent LBBAP lead parameters: threshold 0.8 ± 0.4 V at 0.4 ms; sensing 9.4 ± 4.2 mV; impedance 627 ± 131 Ω. Acute procedural complications included damaged lead helix requiring a second lead (4.3%), pneumothorax (2.9%), and acute LBBAP lead dislodgment (1.4%). Septal perforation occurred in 10.1% of cases with no acute sequelae. When analyzed in tertiles, the number of lead deployment attempts was significantly reduced with no changes to procedural success rates with increasing experience.
CONCLUSION: Adoption of LBBAP with stylet-driven lead in an academic training center is feasible and safe, with satisfactory success rates and no overly steep learning curve.
METHODS: This study is interventional research with a pretest and posttest design with a control group. The research population included all patients who were candidates for brain and nerve surgery in the teaching-treatment hospitals in 2019. The samples were selected by probability and simple random sampling methods. The data collection tool included the Spielberger questionnaire and demographics (age, gender, marital status, education degree, job, etc.) and the vital signs checklist (blood pressure, heart rate, and respiration).
RESULTS: The results of this study showed that the sound of the Quran leads to a decrease in the level of anxiety in the experimental group. The effect size of the group for overt anxiety and anxiety subscales is 53.5% and 40%, respectively; blood pressure is 4.3%, breathing is 20.9%, and heart rate is 21.5%.
CONCLUSION: Anxiety is an unpleasant complication that many people suffer from before various surgeries. The results of this study indicated that the sound of the Quran is a positive and effective factor in reducing anxiety before neurosurgery in Muslim patients who are candidates for this surgery, so health policymakers can use the results of this study as a research priority to reduce anxiety before surgery.
AIM: This research attempts to analyze the morphology of the dorsal surface of the tongue of G. chamaeleontinus by using the scanning electron microscope (SEM) and its histological structure by using hematoxylin-eosin (HE) staining.
METHODS: This study achieves the SEM and light microscope images using hematoxylin eosin stains and employs six samples of G. chamaeleontinus.
RESULTS: The tongue of G. chamaeleontinus separated into three distinct parts: the apex (A), corpus (C), and radix ®. The structure's A contains dome-shaped papillae (DP). The C section contains DP and circumvallate papillae. The R contains scale-like papillae. Additionally, histological analysis using HE stains revealed the taste buds on the DP and circumvallate papillae and the presence of lingual salivary glands (SG) on the lamina propria mucosa.
CONCLUSION: The tongue's papillae of G. chamaeleontinus comprise sensory and mechanic papillae, which are also completed by lingual SG.
PURPOSE: This study explored the lived experiences of older adults with functional limitations in retrofitted senior living facilities, specifically focusing on how bathroom microenvironments unique to these settings impact their safety, autonomy, and fall risks.
METHODS: In-depth, semi-structured interviews were conducted with 14 older adults in four urban senior living facilities. Moustakas' transcendental phenomenology and the Modified Stevick-Colaizzi-Keen method were employed to analyze the data.
RESULTS: Four primary themes emerged: navigating bathroom barriers, psychological strain in daily navigation, safety through adaptation, and economic and cultural barriers to bathroom safety. The findings expose a stark reality: retrofitted senior living facilities frequently fail to meet the safety and accessibility needs of older adults, forcing them to adapt to spaces that compromise both their dignity and independence.
CONCLUSION: These systemic shortcomings in bathroom microenvironments highlight a critical focus for retrofitting efforts: functionality, safety, and the evolving needs of older adults to create environments that promote autonomy and reduce fall risks. Anything less is not just a missed opportunity-it is a failure to respect the fundamental rights and well-being of an aging population.
