Objective:To investigate the clinical characteristics and treatment outcomes of patients with blast-induced hearing loss（BIHL）. Methods:The clinical features, laboratory parameters, audiometric profiles, and treatment efficacy of patients with blast induced hearing loss and those with idiopathic sudden hearing loss（ISHL） were analyzed using t-tests, Wilcoxon rank-sum tests, and chi-square tests, with a significance level set at P<0.05. Results:A total of 59 patients in the BIHL group and 117 patients in the ISHL group were included in this study. The mean age of the BIHL group was（39.07±14.49） years, comprising 45 males and 14 females. After the blast, 21 patients went to the hospital within the initial 14-day period, and an additional 38 patients seeking admission thereafter. In the BIHL group, 33 patients had unilateral hearing loss with PTA of （50.30±28.85） dB HL, while 26 had bilateral hearing loss with a PTA of（44.54±26.22） dB HL. In comparison, among the ISHL group, 112 patients had unilateral hearing loss with a PTA of（56.28±14.19） dB HL, and 5 had bilateral involvement with a PTA of（56.25±35.14） dB HL. The effective treatment rate within 14 days for the BIHL group was 31.8%, while for the ISHL group, the effective rate within 14 days was 77.0%. Conclusion:Blast-induced hearing loss is caused by exposure to high-intensity noise. The overall treatment effectiveness during hospitalization is lower compared to idiopathic sudden hearing loss, and the treatment window is shorter. Therefore, greater emphasis should be placed on prevention.

Objective:To summarize medication safety assessment tools for clinical nurses both domestically and internationally.Methods:Guided by the Joanna Briggs Institute (JBI) scoping review methodology, a systematic search was conducted across CINAHL, Embase, PubMed, Web of Science, SinoMed, China National Knowledge Infrastructure, and WanFang Data. The search period was from the establishment of database to January 1, 2025. Medication safety assessment tools for clinical nurses were extracted, relevant content was systematically analyzed, and the retrieval results were reported in a standardized manner.Results:A total of 28 studies were included, involving 15 medication safety assessment tools for clinical nurses. Assessment methods employed multidimensional and graded self-assessment formats. Based on evaluation perspectives, these tools were categorized into six types, including operational standardization monitoring, cognitive bias calibration, environmental stress testing, capability threshold identification, reporting barrier analysis, and medication information systems. The assessment tools had high reliability and validity, multiple types, and diverse evaluation perspectives.Conclusions:Researchers should carefully select and use assessment tools based on research characteristics. It is necessary to enhance the autonomy of nursing research on medication safety, develop comprehensive and accurate clinical nurse medication safety assessment tools that are adapted to China's clinical context, and promote the improvement of nurse medication safety.

Objective:The purpose of this study was to investigate the diagnostic value and clinical significance of cochlear microphonics (CM) combined with otoacoustic emission (OAE) in patients with auditory neuropathy (AN).Methods:The study included patients who were diagnosed with bilateral AN and had CM originating from both sides. The CM amplitude, latency, duration and intensity-amplitude (I/O) function curve were recorded by CM test. According to whether the distortion product otoacoustic emissions (DPOAE) passed through, the patients were divided into three groups: bilateral OAE passed group (OAE PP Group), bilateral OAE failed group (OAE RR Group), and unilateral OAE passed through one side failed group (OAE PR Group). OAE was elicited by four or more frequencies of 750-8 000 Hz. The characteristics of CM and its related influencing factors were analyzed, and data were processed and analyzed by SPSS 26.0 software. Results:(1) A total of 256 patients (512 ears) with AN were enrolled, including 161 patients (322 ears) in OAE PP group, 32 patients (64 ears) in OAE PR group and 63 patients (126 ears) in OAE RR group. OAE failed in 30.9% of patients with AN. (2) When the stimulation intensity was 100 dB nHL, the CM amplitude of OAE passing ear (OAE P+CM P group) in AN patients aged 3 years was 0.43±0.17μV, which was significantly higher than that of OAE not passing ear (OAE R+CM P group) (0.29±0.15) μV ( t=4.876， P<0.001). The CM duration of the OAE P+CM P group was (5.18±1.04) ms, which was longer than that of the OAE R+CM P group at 4.60±1.12 ms ( P=0.005). The I/O function curve of OAE P+CM P group showed a nonlinear trend, while, that of OAE R+CM P group showed a linear trend. (3) In the OAE P+CM P group of AN patients, the amplitude of CM was negatively correlated with the onset age, test age, disease course, PTA, and ASSR threshold ( P<0.001), with correlation coefficients of r=-0.475, r=-0.519, r=-0.367, r=-0.374, and r=-0.494, respectively. In the OAE R+CM P group of AN patients, the amplitude of CM was negatively correlated with the onset age, test age, and ASSR threshold ( P<0.05), with correlation coefficients of r=-0.271, r=-0.240, and r=-0.287, respectively. Conclusions:Excluding patients with high-frequency steeply sloping hearing loss, when ABR is absent or abnormal and OAE is absent, CM detection can reduce the rate of missed diagnosis of AN. The analysis of CM amplitude and I/O function curve is helpful to determine the lesion site of AN patients, which is convenient for early diagnosis and effective intervention.

BACKGROUND: The American Heart Association (AHA) introduced the concept of cardiovascular-kidney-metabolic (CKM) health and stage, reflecting the interaction among metabolism, chronic kidney disease (CKD), and the cardiovascular system. However, the association between CKM stage and the long-term risk of cardiovascular disease (CVD) has not been validated. This study aimed to evaluate the long-term CVD risk associated with CKM health metrics and CKM stage using data from a population-based cohort study. METHODS: In total, 5293 CVD-free participants were followed up to around 13 years in the Chinese Multi-provincial Cohort Study (CMCS). Considering the pathophysiologic progression of CKM health metrics abnormalities (comprising obesity, central adiposity, prediabetes, diabetes, hypertriglyceridemia, CKD, and metabolic syndrome), participants were divided into CKM stages 0, 1, and 2. The time-dependent Cox regression models were used to estimate the cardiovascular risk associated with CKM health metrics and stage. Additionally, broader CVD outcomes were examined, with a specific assessment of the impact of stage 3 in 2581 participants from the CMCS-Beijing subcohort. RESULTS: Among participants, 91.2% (4825/5293) had at least one abnormal CKM health metric, 8.8% (468/5293), 13.3% (704/5293), and 77.9% (4121/5293) were in CKM stages 0, 1, and 2, respectively; and 710 incident CVD cases occurred during a median follow-up time of 13.3 years (interquartile range: 12.1 to 13.6 years). Participants with each poor CKM health metric exhibited significantly higher CVD risk. Compared with stage 0, the hazard ratio (HR) (95% confidence interval [CI]) for CVD incidence was 1.31 (0.84-2.04) in stage 1 and 2.27 (1.57-3.28) in stage 2. Significant interactive impacts existed between CKM stage and age or sex, with higher CVD risk related to increased CKM stages in participants aged <60 years or females. CONCLUSION These findings highlight the contribution of CKM health metrics and CKM stage to the long-term risk of CVD, suggesting the importance of multi-component recognition and management of poor CKM health in CVD prevention.
