This paper focuses on whether masking signal with natural sounds is an effective way for mitigating annoyance caused by monotone-like tinnitus. Four natural sounds, pink noise, and narrow bandwidth noise were applied as maskers in the present study shown in this paper. Two monotones were applied as maskees. As a basis for research, natural sounds do not necessarily mask monotones entirely. According to the results, spring water and rain noise can be selected as effective noise for masking monotones. In the case of monotones with different frequency, the same masker performed a little differently on masking. We preliminarily demonstrated the feasibility of natural sounds for masking monotone-like tinnitus, which is of great use for improving maskers in tinnitus masking therapy.
The ideological and political education in standardized residency training plays an important role in cultivating medical talents with noble medical ethics and exquisite medical skills. Teaching evaluation is an important method to promote teaching improvement and optimization. However, there are still some problems and challenges in the evaluation of ideological and political education for standardized residency training. This article proposes the ideological and political education of standardized residency training can be comprehensively evaluated by the context-input-process-product evaluation model from four aspects: background, input, process, and result evaluation. The aim is to provide solid support and guidance for the ideological and political education route in standardized residency training.
Objective To investigate the information of label use of high-alert drugs for children of high risk population, in the Military General Hospital of Beijing PLA. Methods We selected high-alert drugs used in this hospital as objectives. The package inserts of these drugs were investigated and medication parts for children were analyzed. Results 201 drugs regarded as high-alert drugs were included, of which only 78 drugs have accurate detailed description of medication for children, accounting for 38.8% of the total of investigated high-alert drugs. Conclusion Children, as high-risk population, needs more attention concerning the use of high-alert drugs. However, risks in the use of high-alert drugs increased due to the lack of the information of label use of high-alert drugs. To ensure the safety of drug use in children, the information of drug use for children in the package inserts should be urgently supplemented.
ObjectiveTo evaluate the value and experience of the multidisciplinary team (MDT) approach in the management of patients with lower extremity arteriosclerosis obliterans (ASO). MethodsA retrospective analysis was conducted on 46 consecutive patients with lower extremity ASO who were treated with MDT model at Zhongshan Hospital, Fudan University, from May 2021 to April 2024. All subjects had critical limb ischemia (Rutherford category ≥4) with comorbidities involving two or more organ systems. Overall mortality, above-ankle amputation rate, and below-ankle amputation rate were recorded. The frequency and depth of involvement of each specialty in the MDT process were also documented. ResultsOf the 46 patients, 37 were male and 9 were female, with a age of (74.3±11.8) years. Major comorbidities included heart disease, hypertension, cerebrovascular disease, diabetes, chronic kidney disease, hyperlipidemia, and others. Overall mortality was 13.0% (6/46). The total amputation rate was 32.6% (15/46), comprising above-ankle amputation in 19.6% (9/46) and below-ankle amputation in 13.0% (6/46). Fourteen disciplines participated in the MDT; in addition to vascular surgery, the most actively involved departments were endocrinology, cardiology, and nephrology. ConclusionsThe MDT model offers unique advantages in the management of critical lower-extremity ASO. By coordinating revascularization timing, extent, and modality, prioritizing comorbid conditions, tailoring operative plans, and optimizing perioperative support, the MDT approach reduces mortality, improves limb salvage rate, and enhances both prognosis and quality of life.
