Objective: The increase in patient flow, replacement of medical equipment, and variations in surrounding environments induce increasingly serious acoustic environment problems in hospitals. This study aims to provide additional bases for the formulation of subsequent management plans in clinical practice by analyzing the influence of the acoustic environment in wards and the postoperative rehabilitation effect among patients with oral cancer.

Methods: The medical records of 210 patients with oral cancer undergoing surgical treatment in Jinan Stomatological Hospital from February 2020 to October 2022 were selected for retrospective analysis. Patients with the acoustic environment in wards >55 and ≤55 dB were classified as groups A and B, respectively, according to the acoustic environment in wards. The effects of the acoustic environment in wards on postoperative blood pressure, blood viscosity, and blood glucose fluctuation (BGF) were observed to further analyze their relationship.

Results: No significant difference was observed in indices such as preoperative systolic pressure (SP), diastolic pressure (DP), cardiac output (CO), postoperative CO, total cholesterol, and low- and high-density lipoproteins between the two groups (P > 0.05). The SP, DP, whole blood low-shear viscosity (WBLSV), whole blood middle-shear viscosity (WBMSV), whole blood high-shear viscosity (WBHSV), and BGF in group B were significantly lower than group A (P < 0.05). Correlation results showed that the total mean value of the acoustic environment in wards was positively correlated with SP, DP, WBLSV, WBMSV, WBHSV, and BGF (P < 0.05).

Conclusion: The high acoustic environment in wards is significantly positively correlated with postoperative blood pressure, blood viscosity, and BGF in patients with oral cancer. The hospital should focus on and strengthen the management of the acoustic environment in wards, providing additional schemes to promote the postoperative recovery of patients with oral cancer.

Objective: This study aimed to evaluate the management effect of music therapy on the psychological health of patients undergoing maintenance hemodialysis (MHD), with focus on improving levels of depression, anxiety and stress.

Methods: A retrospective analysis of clinical data was conducted for 218 patients with sleep disorders accompanied by hemodialysis (HD) from January 2020 to December 2023. The subjects were categorized into a control group comprising 122 cases and an observational group comprising 96 cases. The observation group received music therapy in addition to routine management for 3 months. The psychological health status of patients was assessed using the Self-rating Depression Scale (SDS), Self-rating Anxiety Scale (SAS), and Hemodialysis Stressor Scale (HSS), among other indicators. t Tests, χ2 test and Wilcoxon test were performed.

Results: After 3 months, the SDS and SAS scores of the observation group were significantly lower than those of the control group (P < 0.05). The scores for the "psychological stressors," "physiological stressors" and "social stressors" dimensions of HSS were also significantly lower in the observation group compared with those in the control group (P < 0.05). The overall satisfaction rate of the observation group was significantly higher than that of the control group (96.88% vs. 88.52%, P = 0.022).

Conclusion: Music therapy exerted a positive effect on improving the psychological health of HD patients, particularly in reducing stress levels. This study provides clinical evidence for music therapy as a low-cost and effective adjunctive treatment.

Background: Otitis media (OM) refers to a common clinical ear disease. Noise seriously damages human hearing function. This study aimed to investigate the effects of various noise types on the hearing function of patients who have recovered from mild OM.

Materials and methods: A total of 160 patients with mild OM treated at our hospital from May 2020 to May 2023 were retrospectively selected for this study. Based on clinical data, the patients were divided into the non-noise group (n = 80) and the noise (n = 80) group. The hearing thresholds of the two groups were compared across various noise types at 500, 1000, and 2000 Hz. In addition, the hearing thresholds of the noise group were compared under the same conditions.

Results: The noise group exhibited significantly higher hearing thresholds at 500, 1000, and 2000 Hz than the non-noise group (P < 0.05). Under traffic, urban construction, and industrial noises, the auditory thresholds at 500, 1000, and 2000 Hz in the noise group were significantly higher than those observed under domestic and speech noises (P < 0.05).

Conclusion: Noise shows a close relationship with the hearing function of patients with OM. Traffic, urban construction, and industrial noises greatly influence the hearing function of patients who have recovered from mild OM.

Due to the abnormal structure and function of brain neural networks in special populations, such as children, elderly individuals, and individuals with mental disorders, noise exposure is more likely to have negative psychological and cognitive nonauditory effects on these individuals. There are unique and complex neural mechanisms underlying this phenomenon. For individuals with mental disorders, there are anomalies such as structural atrophy and decreased functional activation in brain regions involved in emotion and cognitive processing, such as the prefrontal cortex (PFC). Noise exposure can worsen these abnormalities in relevant brain regions, further damaging neural plasticity and disrupting normal connections and the transmission of information between the PFC and other brain areas by causing neurotransmitter imbalances. In the case of children, in a noisy environment, brain regions such as the left inferior frontal gyrus and PFC, which are involved in growth and development, are more susceptible to structural and functional changes, leading to neurodegenerative alterations. Furthermore, noise exposure can interrupt auditory processing neural pathways or impair inhibitory functions, thus hindering children's ability to map sound to meaning in neural processes. For elderly people, age-related shrinkage of brain regions such as the PFC, as well as deficiencies in hormone, neurotransmitter, and nutrient levels, weakens their ability to cope with noise. Currently, it is feasible to propose and apply coping strategies to improve the nonauditory effects of noise exposure on special populations based on the plasticity of the human brain.

Purpose: This investigation sought to systematically assess music therapy's impact on aphasia and cognition in patients with post-stroke.

Methods: Comprehensive searches were performed across major databases, including PubMed, Web of Science, Embase, Cochrane Library, China National Knowledge Infrastructure, and Vip Chinese sci-tech periodicals (VIP), covering publications up to December 2023. After screening and extracting data from the retrieved literature, its quality was appraised, which was followed by a meta-analysis using RevMan software (version 5.4, Cochrane Collaboration, Oxford, UK).

Results: Nine articles, which were published from 2008 to 2022, were covered in this investigation, comprising 309 stroke patients in total. Meta-analysis results from these variations were found to be not statistically significant in the degree of functional communication improvement between the experimental group and the control group (standardized mean difference [SMD] = 0.23, 95% confidence interval [CI] (-0.19; 0.77), P > 0.05). These variations were found to be not statistically significant in the improvement of understanding ability in the experimental group compared with that in the control group (SMD = 0.21, 95% CI [-0.66; 1.09], P > 0.05). The degree of improvement in repetitive ability of the experimental group was considerably greater than that of the control group (SMD = 0.37, 95% CI [0.01; 0.76], P < 0.05). These variations were found to be not statistically significant in the improvement of naming ability in the experimental group compared with that in the control group (SMD = 0.30, 95% CI [-0.19; 0.80], P > 0.05). The cognitive score of the experimental group was considerably greater than that of the control group (SMD = 0.75, 95% CI [0.44; 1.06], P < 0.05).

Conclusion: Music therapy can effectively ameliorate the repetition ability of patients with aphasia after stroke. It can also improve the cognitive ability of patients. Thus, music therapy could be further applied to treat this type of patients.

Objective: Excessive noise is unpleasant and induces several physiological and psychological effects. Noise pollution is a potential threat to humans, particularly those continuously exposed for extended periods throughout the day over many years. This review aims to examine the various auditory and non-auditory outcomes associated with prolonged exposure to noise pollution.

Materials and methods: The review utilized a combination of relevant keywords to search the electronic databases. After screening based on the applied selection criteria for title, abstract, and full text, 44 articles were finally selected for critical review.

Results: We identified and analyzed research findings related to noise-induced hearing loss, tinnitus, and sleep disturbances along with non-auditory issues such as annoyance, cognitive impairments, and mental stress associated with cardiovascular disorders. Furthermore, the existing studies were compared and collated to highlight the unique challenges and significance of noise pollution as a distinctive environmental concern and to explore the ongoing efforts in its research and prevention, including the early detection and potential reversal of noise-induced hearing loss.

Conclusion: The fundamental health consequences of noise pollution underscore the need for extensive research encompassing emerging noise sources and technologies to establish a health management system tailored to address noise-related health concerns and reduce noise exposure risk among populations. Finally, further research is warranted to ensure improved measurement of noise exposure and related health outcomes, especially in the context of occupational noise.

Objective: This study aims to investigate the impact of noise reduction nursing in ward on patients who underwent intracranial aneurysm embolization.

Methods: Between April 2020 and March 2021, Funan County People's Hospital implemented standard nursing care for patients who underwent intracranial aneurysm embolization, comprising 55 patients admitted during this period, constituting the control group. Subsequently, from April 2021 to March 2022, the hospital introduced noise reduction nursing measures in wards. A total of 65 patients admitted during this period were included in the study group. Data on noise levels, emotional states, and sleep statuses were collected from both groups. The comprehensive impact of noise reduction nursing on the mental and physical health of patients who underwent intracranial aneurysm embolization was evaluated.

Results: Before propensity score matching (PSM), significant differences were observed in age and intracranial aneurysm diameter between the two groups (P < 0.05). However, following PSM, a total of 102 patients were included in the analysis, and no significant differences in baseline data were observed between the two groups (P > 0.05). The noise level in the study group's ward was significantly lower than that in the control group (P < 0.05). In addition, post-management, the study group exhibited lower Self-rating Anxiety Scale scores and total scores of Pittsburgh Sleep Quality Index compared with the control group. Moreover, the Glasgow Coma Scale score was higher in the study group, demonstrating statistical significance (P < 0.05).

Conclusion: The implementation of noise reduction nursing in wards effectively controls ward noise levels and improves negative mood and sleep quality among patients who underwent intracranial aneurysm embolization. These findings indicate that noise reduction nursing facilitates postoperative rehabilitation and enhances patient outcomes.

Objective: To explore the effects of music nursing as a complementary therapy on anxiety, fatigue, and quality of life in children with acute leukemia (AL).

Methods: This study included 150 children with AL admitted to our hospital from August 2021 to August 2023 and divided them into two groups based on treatment: the control (n = 76, received routine nursing) and observation (n = 74, received music nursing on the basis of routine nursing) groups. Comparison of groups was performed in terms of general information, anxiety, fatigue, and quality of life at admission (T0) and 1 month after admission (T1).

Results: No significant differences were observed in the general data between the two groups (P > 0.05). Anxiety, fatigue, and quality of life of the two groups also showed no significant differences at T0 (P > 0.05). The observation group showed significantly lower anxiety than the control group at T1 (P < 0.05). At T1, the observation group exhibited a lower fatigue degree compared with the control group (P < 0.05). At T1, the observation group attained higher scores on physiological and emotional dimensions of the quality of life compared with the control group, and the differences were statistically significant (P < 0.05).

Conclusion: Music nursing for AL children, which has a certain clinical application value, can effectively reduce their anxiety and fatigue and improve their quality of life.

Background: Environmental noise damages the cardiovascular system and endangers human health. This study was conducted to analyze the relationship between noise exposure and prognosis of patients with heart failure and to provide a good strategy for disease treatment.

Methods and materials: This study was a retrospective analysis. A total of 487 patients with heart failure admitted to Ganzhou People's Hospital from September 2021 to September 2023 were selected as research subjects, and they were divided into the low noise exposure group (<55 dB; group A) and the high noise exposure group (≥55 dB; group B) according to the noise exposure conditions. The baseline data and physiological indicators of the two groups were analyzed.

Results: In this study, 84 patients were included in group B, and the remaining 403 patients were included in group A. Group A had lower systolic pressure, diastolic pressure, heart rate, and respiratory rate compared to group B (P < 0.05). The serum B-type natriuretic peptide (BNP) level in group A was lower than that in group B (P < 0.001). Group B had significantly higher scores on the Self-rating Anxiety Scale (SAS) and Self-rating Depression Scale (SDS) compared to group A (P < 0.001). The noise level was correlated with SAS score, SDS score, and serum BNP level (all P < 0.001).

Conclusion: The noise exposure is correlated with the prognosis of patients with heart failure, suggesting that active strategies should be adopted to reduce the impact of noise on their disease.

Objective: This study aimed to determine the postoperative effects of music therapy on negative emotions, pain, and inflammatory and physiological parameters in patients undergoing colonoscopic polypectomy.

Methods: Patients who underwent colonoscopic polypectomy in Funan County People's Hospital between March 2020 and June 2023 were selected as the research subjects. Patients were divided into exposure (underwent music therapy) and control (did not undergo music therapy) groups. Baseline characteristics, Self-rating Anxiety Scale (SAS) and Visual Analog Scale (VAS) scores, physiological parameters [systolic blood pressure (SBP), diastolic blood pressure (DBP), and heart rate (HR)], and inflammatory marker levels [neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR), and erythrocyte sedimentation rate (ESR)] of patients before and after exposure to music were determined. The propensity score matching (PSM) method (1:1) was used to balance the baseline characteristics of the two groups.

Results: After PSM, the exposure group comprised 50 cases and the control group comprised 50 cases. The baseline characteristics were not significantly different between the two groups (P > 0.05). The postoperative SAS score of the exposure group was significantly lower than that of the control group (P < 0.05). Meanwhile, the postoperative VAS score of the exposure group was nonsignificantly lower than that of the control group (P > 0.05). Furthermore, the postoperative SBP, DBP, and HR levels of the exposure group were significantly lower than that of the control group (P < 0.05). The postoperative levels of NLR, PLR, and ESR were not significantly different between the exposure and control groups (P > 0.05).

Conclusion: Music therapy exerts beneficial effects on the postoperative psychological and physiological parameters of patients undergoing colonoscopic polypectomy.
