Precise fluid administration is important to prevent hypo- or hypervolemia. However, the accuracy of scales marked on intravenous (IV) fluid plastic bags had remained unknown. Ten 1 L sized IV crystalloids were prepared from each of three manufacturers (H, J, and D). At each scale, the actual volume of the IV fluid was measured. Differences with the measured volumes for each scale were investigated between the three manufacturers. All initial total volume was greater than 1 L. Except for the full-filled level, H overfilled, whereas J and D filled less. For J and D, the maximal differences between the scale and the measured volume were about 200 mL. Fluid volumes of each scale were significantly different among the three manufacturers (P < 0.001). It is inaccurate to measure the amount of fluid depending on the IV bag scales. Clinicians must use electronic infusion pumps for accurate fluid administration.

Background: and Purpose Parkinson’s disease (PD) significantly impacts the quality of life via both motor and nonmotor symptoms. Exercise is a valuable nonpharmacological intervention that can alleviate PD symptoms and slow disease progression. Understanding the factors that motivate and restrict exercise in PD patients is essential for promoting engagement.This study aimed to identify the motivators and barriers affecting exercise in PD patients. Methods: This cross-sectional study assessed exercise habits, motivators, and barriers among PD patients with a modified Hoehn and Yahr stage of ≤2.5. Participants were categorized into non-, low-, and high-exercise groups based on the World Health Organization guidelines. The International Physical Activity Questionnaire, the Korean version of the Sport Motivation Scale, and a barriers-to-exercise questionnaire were utilized. Results: Data from 165 of 196 enrolled patients were analyzed: 28 (17.0%), 88 (53.3%), and 49 (29.7%) in the non-, low-, and high-exercise groups, respectively. The nonexercise group demonstrated higher levels of fatigue and apathy, and more-severe cardiovascular, mood, intellectual, attention, gastrointestinal, and urinary symptoms. While all groups recognized the benefit of exercise, those in the nonexercise group viewed PD symptoms and depressive mood as major barriers, whereas those in the high-exercise group were primarily motivated by personal satisfaction. Conclusions This study highlights the importance of enjoyment and personal satisfaction to the maintenance of exercise habits among PD patients. By enhancing specific motivators and overcoming barriers, particularly PD symptoms and related nonmotor symptoms, tailored interventions can be implemented to increase exercise adherence and, eventually, improve the quality of life of PD patients.

Objective: Recent studies highlighted the triple-network model which illustrated the interactions among three large-scale networks including salience network (SN). The functional magnetic resonance imaging used in this study was designed to investigate the characteristics of three large-scale networks associated with the thought-action fusion (TAF) in patients with obsessive-compulsive disorder (OCD) using power spectral density (PSD) analysis. Methods: This study included 32 OCD patients and 38 age-matched healthy controls (HC). The TAF task was modified from the experiment of Rassin. PSD from time courses in large-scale networks of each subject was measured to compare between the groups for both TAF and resting state. Results: In SN, OCD reported lower power in the low-frequency domain of SN compared to HC using the two-sample t test during the TAF task (t = −2.395, p = 0.019) but not in the resting state. The PSD in the low-frequency domain of the SN had a significant negative correlation with state score in the guilty inventory (r = −0.361, p = 0.042) in OCD patients. Conclusion This study suggests that OCD patients showed reduced SN power which can be prominent in a certain situation, such as TAF. In addition, the PSD alterations in SN cause difficulty in processing ambiguous emotional cues in social situations, and the difficulty can be connected with a negative feeling (e.g., guilt).

Objective: To assess the feasibility, efficacy, and safety of targeted embolization for cavernous sinus dural arteriovenous fistulas (CSDAVF). Materials and Methods: This retrospective study investigated patients with CSDAVF who underwent endovascular treatment at a tertiary hospital between October 1991 and March 2023. Treatment strategies were determined based on clinical symptoms and shunt characteristics. Targeted or non-targeted curative embolization was performed to achieve complete shunt occlusion.Initially, targeted embolization, selective occlusion of the shunted pouch while preserving the normal cavernous sinus lumen, was conducted, should that fail, non-targeted embolization was performed. In contrast, palliative embolization solely reduced shunt flow. Clinical signs, imaging characteristics, and outcomes were evaluated according to the agreed treatment strategy. Results: In total, 198 patients with CSDAVF (mean age 59.0 ± 12.1 years, 23.2% male) participated in this study. Of which, 94 patients (47.5%) were treated with targeted embolization, 75 (37.9%) with non-targeted embolization, and 29 (14.6%) with palliative treatment. For patients undergoing curative embolization, 55.7% (94/169) successfully achieved targeted embolization; this procedure was usually used to treat focal fistulas (restrictive or late-restrictive types), whereas diffuse fistulas (proliferative type) often underwent non-targeted or palliative embolization. For patients that underwent targeted embolization, the rate of complete or near-complete occlusion on immediate post-treatment digital subtraction angiography was 93.6% (88/94), with a complication rate of 2.1% (2/94), symptom improvement rate of 96.8% (91/94), and retreatment rate of 5.3% (5/94). No serious complications were reported during follow-up. Conclusion When successful, targeted embolization of CSDAVF causes low rates of cranial nerve palsy, retreatment, and good clinical outcomes.
