An expedited model for identifying potential patients with periodic leg movements.

Periodic leg movements during sleep (PLMS) may have crucial consequences in adults. This study aimed to identify baseline characteristics, symptoms, or questionnaires that could help to identify sleep-disordered breathing patients with significant PLMS. Patients aged 20-80 years who underwent polysomnography for assessing sleep disturbance were included. Various factors such as sex, age, body measurements, symptoms, apnea-hypopnea index (AHI), and sleep quality scales were analysed to determine the presence of PLMS. The study included 1480 patients with a mean age of 46.4 ± 13.4 years, among whom 110 (7.4%) had significant PLMS with a PLM index of 15 or higher. There were no significant differences observed in terms of sex or BMI between patients with and without significant PLMS. However, the odds ratios (OR) for PLMS were 4.33, 4.41, and 4.23 in patients who were aged over 50 years, had insomnia, or had an ESS score of less than 10, respectively. Notably, the OR increased up to 67.89 times in patients who presented with all three risk factors. Our analysis identified significant risk factors for PLMS: age over 50, self-reported insomnia, and lower daytime sleepiness levels. These findings aid in identifying potential PLMS patients, facilitating confirmatory examinations and managing associated comorbidities.

Multi-Omics Analysis Reveals the IFI6 Gene as a Prognostic Indicator and Therapeutic Target in Esophageal Cancer.

The role of the IFI6 gene has been described in several cancers, but its involvement in esophageal cancer (ESCA) remains unclear. This study aimed to identify novel prognostic indicators for ESCA-targeted therapy by investigating IFI6's expression, epigenetic mechanisms, and signaling activities. We utilized public data from the Gene Expression Omnibus (GEO) and the Cancer Genome Atlas (TCGA) to analyze IFI6's expression, clinical characteristics, gene function, pathways, and correlation with different immune cells in ESCA. The TIMER2.0 database was employed to assess the pan-cancer expression of IFI6, while UALCAN was used to examine its expression across tumor stages and histology subtypes. Additionally, the KEGG database helped identify related pathways. Our findings revealed 95 genes positively correlated and 15 genes negatively correlated with IFI6 in ESCA. IFI6 was over-expressed in ESCA and other cancers, impacting patient survival and showing higher expression in tumor tissues than normal tissues. IFI6 was also correlated with CD4+ T cells and B cell receptors (BCRs), both essential in immune response. GO Biological Process (GO BP) enrichment analysis indicated that IFI6 was primarily associated with the Type I interferon signaling pathway and the defense response to viruses. Intriguingly, KEGG pathway analysis demonstrated that IFI6 and its positively correlated genes in ESCA were mostly linked to the Cytosolic DNA-sensing pathway, which plays a crucial role in innate immunity and viral defense, and the RIG-I-like receptor (RLR) signaling pathway, which detects viral infections and activates immune responses. Pathways related to various viral infections were also identified. It is important to note that our study relied on online databases. Given that ESCA consists of two distinct subgroups (ESCC and EAC), most databases combine them into a single category. Future research should focus on evaluating IFI6 expression and its impact on each subgroup to gain more specific insights. In conclusion, inhibiting IFI6 using targeted therapy could be an effective strategy for treating ESCA considering its potential as a biomarker and correlation with immune cell factors.

Prevalence of hearing loss, tinnitus, vertigo and sudden deafness among patients with polymyositis and dermatomyositis.

Little is known about a possible association of autoimmune inner ear disease among patients diagnosed with polymyositis (PM)/dermatomyositis (DM). This study aimed to explore differences in the prevalence of inner ear symptoms among patients with and without PM/DM using a nationwide population-based dataset. Data for this study were retrieved from the Taiwan National Health Insurance Research Database. The study sample included 1622 patients diagnosed with PM/DM and 8109 propensity-score matched comparison patients without PM/DM. We performed multivariate logistic regressions to calculate odds ratios (ORs) and 95% confidence interval (CI) for tinnitus, hearing loss, sudden deafness, and vertigo among patients with PM/DM versus comparison patients. Chi-square tests showed statistically significant differences between patients with PM/DM and comparison patients in the prevalence of tinnitus (16.1% vs. 12.7%, p < 0.001), non-conductive hearing loss (9.2% vs. 6.8%, p < 0.001), and vertigo (14.4% vs. 11.1%, p < 0.001). The adjusted ORs for tinnitus, non-conductive hearing loss, and vertigo, respectively, were 1.332 (95% CI = 1.147-1.547), 1.399 (95% CI = 1.154-1.696), and 1.374 (95% CI = 1.173-1.611) for patients with PM/DM when compared to comparison patients. Our study finds that patients with PM/DM have higher prevalence rates of tinnitus, non-conductive hearing loss, and vertigo than comparison patients.

Association of thyroid cancer with human papillomavirus infections.

While Human Papillomavirus (HPV) particles have been detected in a small proportion of benign thyroid nodules or thyroid cancer cases, a role of HPV in these thyroid conditions has not been established. This study aims to investigate the association of HPV infection with thyroid cancer (TC) using a nationwide population-based study. We retrieved data for this case-control study from Taiwan's Longitudinal Health Insurance Database 2010. The study sample included 3062 patients with TC and 9186 propensity-scored matched controls. We employed multivariate logistic regression models to quantitatively evaluate the association of TC with HPV infections after taking age, sex, monthly income, geographic location and urbanization level of the patient's residence, diabetes, hypertension, and hyperlipidemia into considerations. Chi-squared test revealed that there was a significant difference in the prevalence of prior HPV infections between patients with TC and controls (15.3% vs. 7.6%, p < 0.001). The adjusted odds ratio of prior HPV infections for patients with TC was 2.199 (95% CI = 1.939-2.492) relative to controls. The adjusted ORs of prior HPV infections for patients with TC was similar for males and females. Our research suggests a significant link between HPV infection and the development of TC.

Association of prostate cancer with human papillomavirus infections: a case-control study.

BACKGROUND: The highly oncogenic human papillomavirus (HPV) is associated with numerous cancer types. While the role of viruses in the development of certain cancers is well established, the association between HPV infections and prostate cancer remains a subject of ongoing debate. This study aimed to investigate a potential association of prostate cancer with HPV infections utilizing a case-control study. METHODS: We extracted data from the Taiwan Longitudinal Health Insurance Database 2010. We retrieved 5137 patients with prostate cancer as cases and a 3:1 ratio of propensity score-matched patients without prostate cancer (15,411 patients) as controls. Multiple logistic regression analyses were carried out to scrutinize the association of prostate cancer with HPV infections while taking into account age, monthly income category, geographic location and urbanization level of the patient's residence as well as hyperlipidemia, diabetes, hypertension and chronic prostatitis, tobacco use disorder, and alcohol abuse/alcohol dependence syndrome. RESULTS: The data indicate that out of all sampled patients, 1812 (8.8%) had a prior diagnosis of HPV infections before the index date. Among cases and matched controls, HPV infections were diagnosed in 743 (14.5%) and 1069 (6.9%) patients, respectively. The results from the chi-square test demonstrate that individuals with prostate cancer exhibited a significantly higher incidence rate of HPV infections than their control counterparts (p < 0.001). Furthermore, in comparison to controls, individuals with a history of HPV infections had an adjusted odds ratio of 2.321 (95% CI: 2.097~2.568) for developing prostate cancer. Notably, individuals diagnosed with chronic prostatitis were also more likely to be subsequently diagnosed with prostate cancer (adjusted odds ratio=1.586; 95% CI = 1.338~1.879), which aligns with expectations in this context. CONCLUSIONS: We found prostate cancer to be significantly associated with HPV infections, contributing to the mounting body of evidence indicating a plausible connection between the two.

Factors Affecting the Compliance of Curative-Intent Treatment in Patients With Head and Neck Cancer.

Objectives: This study aims to investigate the factors that lead to poor compliance in initiating the treatment in patients with newly diagnosed head and neck cancers. Methods: A total of 193 patients from the head and neck cancer database dated from January 1, 2018 to September 30, 2020, were analyzed. Variables analyzed included age, gender, primary cancer site, T stage, N stage, M stage, overall stage (I-IV), patient's residential distance, and the impact of COVID-19. Univariate and multivariate analyses were used to assess the significance of these variables in relation to the time to receiving on-time treatment as recommended by specialists. Results: Upon multivariate analysis, the advanced stage and residential distance were significantly associated with initial compliance (P < .09). The impact of nasopharyngeal carcinoma (NPC) and COVID-19 shows a borderline significance (P = .224 and P = .184). Conclusions: The overall stage and patient living distance to the healthcare facility, patient with NPC, and the impact of COVID-19 might affect the compliance of initiating a curative-intent treatment in patients with newly diagnosed head and neck cancers.

Acute invasive fungal rhinosinusitis in post-COVID-19 patients in Vietnam.

BACKGROUND: Acute invasive fungal rhinosinusitis (AIFR) is a potentially lethal infection commonly found in immunocompromised patients. It is considered the most aggressive subtype of fungal sinusitis and can lead to severe morbidity and mortality. There was a significant increase in the incidence of AIFR in post-COVID-19 patients compared to AIFR cases before the COVID-19 pandemic. This study aimed to describe the clinical presentation of AIFR associated with COVID-19 illness. METHODS: A retrospective study included 22 patients diagnosed with AIFR with a recent COVID-19 infection. RESULTS: The most frequent disease associated with AIFR was diabetes mellitus (95.5%). The mycological analysis identified infection caused by Aspergillus species in 72.7% of patients. Along with stabilizing hemodynamic parameters and controlling any comorbidities, all patients in the present study underwent combined surgical debridement followed by antifungal medications. The overall survival rate was 72.7%. The chance of developing a fatal outcome was significantly higher if meningitis presented initially (odds ratio 35.63, p < 0.05). CONCLUSION: The presence of meningitis upon initial diagnosis is related to a significantly higher chance of developing a fatal outcome and should be considered, especially in AIFR patients previously treated for COVID-19 infections. Early diagnosis, early use of antifungal agents, aggressive surgical debridement, and control of comorbid conditions remain crucial in managing AIFR.

Associations of Head and Neck Cancer with Hepatitis B Virus and Hepatitis C Virus Infection.

This case-control study investigates the associations between head and neck cancer (HNC), hepatitis B virus (HBV), and hepatitis C virus (HCV) infection. We included 5603 patients who had received a diagnosis of HNC as cases and 16,809 propensity score matching controls. We employed multivariate logistic regression models to evaluate the association of HNC with HBV and HCV infection after taking sociodemographic characteristics and diabetes, hypertension, hyperlipidemia, HPV infection, tobacco use disorder, and alcohol abuse/alcohol dependence syndrome into considerations. Results show that 7.9% of the total sample had been previously diagnosed with HBV infection, with 9.0% prevalence among cases and 7.6% among controls (p < 0.001). The chi-squared test suggests a significant difference in the prevalence of HCV infection between cases and controls (3.3% vs. 2.7%, p = 0.019). The covariate-adjusted odds ratio (OR) of HBV infection in patients with HNC relative to controls was 1.219 (95% CI = 1.093~1.359). Additionally, the adjusted OR of HCV infection in patients with HNC was 1.221 (95% CI = 1.023~1.457) compared to controls. Furthermore, patients with oropharyngeal cancer were more likely to have HCV infection than controls (adjusted OR = 2.142, 95% CI = 1.171~3.918). Our study provides evidence that suggests a potential association between HBV and HCV infections and the risk of HNC.

Association of Nasopharynx Cancer with Human Papillomavirus Infections.

This population-based study aims to examine the association between nasopharyngeal carcinoma and human papillomavirus infections. This study included 2747 individuals aged 20 years and older who were diagnosed with nasopharynx cancer as cases and 13,735 propensity-score-matching controls. Multivariate logistic regression models were employed to quantitatively assess the association of nasopharynx cancer with human papillomavirus infections while considering age, sex, monthly income, geographic location, and urbanization level of the patient's residence as well as diabetes, hypertension, and hyperlipidemia. Our chi-squared test indicated a significant dissimilarity in previous human papillomavirus infection rates between nasopharynx cancer patients and controls (12.7% vs. 7.2%, p < 0.001). The adjusted odds ratio (OR) for prior human papillomavirus infections was found to be significantly higher for nasopharyngeal carcinoma cases compared to controls at a value of 1.869 with confidence interval ranging from 1.640 to 2.128. Among female participants, compared to controls, the adjusted OR of prior human papillomavirus infections was 2.150 (95% CI = 1.763-2.626) in patients with nasopharynx cancer. In male participants sampled in this study, we observed a statistically significant association between prior human papillomavirus infections and nasopharynx cancer (adjusted OR = 1.689; 95% CI = 1.421-2.008). Our study indicates a noteworthy association between previous human papillomavirus infections and nasopharyngeal carcinoma.

Factors Associated with the Underestimation of Manual CPAP Titration Pressure.

During the SARS-CoV-2 pandemic, the use of in-laboratory positive airway pressure (PAP) titration studies was not routinely suggested. PAP pressure prediction calculations are emerging as alternative methods for the treatment of these patients. The underestimation of PAP titration pressure usually leads to unsatisfactory results for PAP therapy. This study aimed to evaluate the factors associated with the underestimation of PAP titration pressure when using PAP pressure prediction equations. Estimated PAP pressure formulas based on body mass index (BMI) and apnea-hypopnea index (AHI) were chosen to validate the accuracy of equations in the successful prediction of titration pressure. Among 341 adult patients diagnosed with obstructive sleep apnea (OSA) by overnight polysomnography (PSG) and who received overnight PAP titration in order to select a successful pressure, the mean age of the total subjects was 55.4 years old and 78.9% of patients were male. The average BMI and AHI scores were 27.1 ± 4.8 and 37 ± 21.7, respectively. After multivariate stepwise regression analysis, the odds ratio of participants with a pretitration AHI was 1.017 (95% CI: 1.005-1.030). Only the severity of OSA was significantly different between the underestimated group and the adequately assessed group. In conclusion, a high AHI, but not BMI, is associated with an underestimated CPAP titration pressure in adult patients with OSA.

Comparative Effectiveness of Combined and Single Neurostimulation and Traditional Dysphagia Therapies for Post-Stroke Dysphagia: A Network Meta-Analysis.

BACKGROUND: Comparative therapeutic benefits of combined and single neurostimulation therapies including neuromuscular electrical stimulation (NMES), pharyngeal electrical stimulation (PES), repetitive transcranial magnetic stimulation (rTMS), transcranial direct current stimulation (tDCS), and traditional dysphagia therapy (TDT) remain unknown in post-stroke dysphagia (PSD) rehabilitation. Therefore, we performed the first network meta-analysis (NMA) to determine comparative effectiveness of combined and single neurostimulation and traditional dysphagia therapies for PSD. METHODS: A frequentist NMA model was performed with therapy effect sizes presented as standardized mean differences (SMD) and corresponding 95% confidence interval (95% CI) for therapy comparisons while netrank function ranked the therapies in R-Software. Meta-regression models for study characteristics were analyzed using Bayesian NMA Model. RESULTS: Overall, 50 randomized controlled studies with 2250 participants were included. NMES + TDT 3.82 (95% CI, 1.62-6.01), tDCS + TDT 3.34 (95% CI, 1.09-5.59), rTMS + TDT 3.32 (95% CI, 1.18-5.47), NMES 2.69 (95% CI, 0.44-4.93), and TDT 2.27 (95% CI, 0.12-4.41) demonstrated very large effect in improving swallowing function. NMES + TDT -0.50 (95% CI, -0.68 to -0.32, rTMS + TDT -0.44 (95% CI, -0.67 to -0.21), TDT -0.28 (95% CI, -0.46 to -0.10), and NMES -0.19 (95% CI, -0.34 to -0.04) demonstrated medium to small effect in reducing pharyngeal transit time (PTT). rTMS -0.51 (95% CI, -0.93 to -0.08) demonstrated medium effect in reducing oral transit time (OTT). No significant therapy comparison differences were found for reducing aspiration/penetration. The highest ranked therapy was NMES + TDT for better swallowing function and reduction of PTT, rTMS for reduction of OTT, and tDCS + TDT for reduction of aspiration/penetration. Therapeutic effects of the therapies were moderated by frequency, sessions, and duration. CONCLUSION: Combined therapies including NMES + TDT, tDCS + TDT, and rTMS + TDT demonstrate better therapeutic effect for improved swallowing function and reduction of PTT, OTT, and aspiration/penetration for PSD.

Degassing a Decellularized Scaffold Enhances Wound Healing and Reduces Fibrosis during Tracheal Defect Reconstruction: A Preliminary Animal Study.

Few efforts have been made regarding the optimization of porcine small intestinal submucosa (SIS) to improve its biocompatibility. This study aims to evaluate the effect of SIS degassing on the promotion of cell attachment and wound healing. The degassed SIS was evaluated in vitro and in vivo, compared with the nondegassed SIS control. In the cell sheet reattachment model, the reattached cell sheet coverage was significantly higher in the degassed SIS group than in the nondegassed group. Cell sheet viability was also significantly higher in the SIS group than in the control group. In vivo studies showed that the tracheal defect repaired by the degassed SIS patch showed enhanced healing and reductions in fibrosis and luminal stenosis compared to the nondegassed SIS control group, with the thickness of the transplanted grafts in the degassed SIS group significantly lower than those in the control group (346.82 ± 28.02 µm vs. 771.29 ± 20.41 µm, p < 0.05). Degassing the SIS mesh significantly promoted cell sheet attachment and wound healing by reducing luminal fibrosis and stenosis compared to the nondegassed control SIS. The results suggest that the degassing processing might be a simple and effective way to improve the biocompatibility of SIS.

A Two-Flap Combination for Auricular Elevation in Microtia Reconstruction.

BACKGROUND: The aims of this study were to describe and evaluate the effectiveness of combined flaps, a modification of the Nagata technique, for providing a reasonable projection for reconstructed auricles. METHODS: The authors modified the Nagata method for covering the cartilage block by introducing a new combined flap technique, including the temporoparietal skin flap and retroauricular flap. The authors compared the shape, size, and position of the reconstructed ear to the opposite ear, and we evaluated postoperative complications and patient satisfaction levels. They verified the effectiveness of the combined flap by assessing flap necrosis, skin color, thickness, hair in the auricular area, and scars. RESULTS: A total of 38 consecutive patients (39 ears) with microtia, aged 6 to 34 years, underwent reconstruction using the modified method and were followed up for 33.6 months on average. The reconstructed auricle's shape was well defined, with 41.0% having good and 15.4% having excellent results. Most cases achieved good and acceptable levels in size, position, medial longitudinal axis angle, and auriculocephalic angles, and 79.9% of patients/their families were satisfied. The authors observed no cases of flap necrosis or hypertrophic scarring, and there were low rates of flap complications, such as unmatched skin color (7.7%), unacceptable thickness (5.1%), or hair and stretch marks (10.3%). CONCLUSIONS: The modified method's reconstructed ear achieved stable projection, symmetric appearance, and obvious anatomical landmarks with high patient satisfaction. The combined flap method showed certain advantages: high survival rate, less skin contrast, no hypertrophic scars, and fewer complications. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

Factors Related to Ventilation Tube Extrusion Time in Children and Adults.

BACKGROUND AND OBJECTIVE: The aim of this study was to investigate the factors affecting extrusion time in both children and adults with ventilation tube (VT) insertion, providing useful information for clinicians for better decision-making, follow strategy, and potentially improve clinical outcomes for these patients. METHODS: Data from patients receiving myringotomy with VT insertion from January 1, 2007, to June 30, 2012, were retrospectively collected and analyzed by the end of 2018. Various factors, including age, gender, history of VT insertion, tympanogram, size of VT used, local finding of tympanic membrane, hypertension, diabetes mellitus, hyperlipidemia, and postoperative ear infection, were included and analyzed to examine the effects of these factors on extrusion time. RESULTS: A total of 447 patients were included in this study (Child group-Adult group = 237:210). The overall average extrusion time was 225.85 days. In the subgroup analysis, the average time was 221.3 days and 231.0 days for children and adults, respectively. The results showed that the VT extrusion time was significantly longer in participants without a history of VT insertion and in those where larger sized VTs were inserted in both age-groups. Male gender had an influence on extrusion time in children. In addition, a history of VT insertion and VT size were determined to be factors related to extrusion before 12 months in children. CONCLUSION: History of VT insertion and VT size were significantly related to VT extrusion time in both children and adults and defined as factors associated with extrusion before 12 months in children. The findings suggest avoiding VT with a diameter < 1 mm and considering an appropriately larger size in patients with a history of VT insertion to optimize VT retention.

Prognostic Factors for the Outcome of Salivary Gland Holmium: YAG Laser Intraductal Lithotripsy.

OBJECTIVES: Holmium: YAG laser has gained its popularity throughout the years and is used to treat sialolithiasis, which helps to overcome the limitations of traditional sialendoscopic lithotripsy for larger-sized salivary stones. However, little information is available regarding factors predicting the success rate of Holmium: YAG laser intraductal lithotripsy. The purpose of this study is to investigate the factors affecting the success rates of Holmium: YAG laser lithotripsy for salivary stones treatment in a tertiary care hospital. METHODS: A retrospective study conducted in patients receiving sialolithiasis surgery under sialendoscopy from May 2013 to March 2015 at Mackay Memorial Hospital, Taiwan. Data on various factors, including patients' age, gender, glands, size of largest stone, multiple stones (≥2 stones), location of the stone (distal duct, middle duct, proximal duct, and hilum), and operative time. The success of the surgery defined as patients without any complaints such as swelling or tenderness. Logistic regression and Fisher exact tests were employed to examine these factors on the success rate. RESULTS: Fifty-four patients who received sialendoscopy surgery with a mean age of 35.74 years old recruited. Logistic regression identified the operation time exceeding 210 minutes showed 23.497 folds higher odd ratio of having a result of operation failure (P < .05). CONCLUSION: The prolonged operation time is the sole independent factor affecting the successful outcome for salivary gland intraductal laser lithotripsy. We recommend operative time be no more than 210 minutes to increase the success rate in salivary gland Holmium: YAG laser intraductal lithotripsy.

Trends in the incidence of peripheral vestibular disorders: a Nationwide population-based study.

Purpose: This study aimed to examines the long-term trend of incidence of peripheral vestibular disorders between 2010 and 2018 in Taiwan. Methods: Study-eligible patients were identified from Taiwan's Longitudinal Health Insurance Database 2005 maintained by the Ministry of Health and Welfare in Taiwan. We retrieved 230,566 patients with a first-time diagnosis of peripheral vestibular disorders between 2010 and 2018. We calculated annual incidence rates of peripheral vestibular disorders per 100,000 population. We used the annual percent change (APC) to test the trend of peripheral vestibular disorders over time. Results: The mean annual incidence rate of peripheral vestibular disorders during the study period was 1489.6 per 100,000 population. Incidence showed a statistically significant steady decrease from 2010 to 2018 with a mean APC of -6.15% (95% CI = -6.97% ~ -5.32%). The decline was led by Meniere's disease (APC = -9.83, 95% CI = -10.66% ~ -8.99%), followed by benign paroxysmal positional vertigo (APC = -3.69, 95% CI = -4.53% ~ -3.03%), vestibular neuritis (APC = -7.85, 95% CI = -8.96 ~ -6.73), and other peripheral vestibular dizziness (APC = -5.56, 95% CI = -6.69% ~ -4.43%). Conclusion: The incidence of peripheral vestibular disorders, overall, and the four major subgroups, benign paroxysmal positional vertigo, Meniere's disease, vestibular neuritis, and other peripheral vestibular dizziness, all decreased substantially, year by year within the 2010-2018 period.

Association of Chronic Kidney Disease with Prior Tinnitus: A Case-Control Study.

This population-based, case−control study aims to explore the relationship between prior tinnitus and the occurrence of chronic kidney disease (CKD) using a nationwide, population-based cohort study. We used data from the Taiwan National Health Insurance Research Database to explore the association of CKD with tinnitus. We identified 15,314 patients aged ≥40 years old with a first-time diagnosis of CKD as the cases. We used propensity-scored matching to select 45,942 controls (1:3 ratio). We performed multivariate logistic regression to estimate the odds ratio (OR) of a prior tinnitus diagnosis among the CKD group vs. the control group. Analysis showed that 770 (1.26%) out of the 61,256 sampled patients had previously diagnosed tinnitus. Chi-square testing revealed a significant difference in the rate of previously diagnosed tinnitus between cases and controls (3.86% vs. 0.93%, p < 0.001). Univariate logistic regression analysis showed an OR of prior tinnitus for cases of 10.249 (95% confidence interval (CI): (8.662~12.126)) relative to controls. In adjusted analysis, cases were more likely than controls to have a prior diagnosis of tinnitus (OR = 10.970, 95% CI = 9.255~13.004, p < 0.001) after adjusting for age, sex, monthly income, geographic location, urbanization level, hypertension, diabetes, coronary heart disease, hyperlipidemia, obesity, and autoimmune disease. Our study shows that CKD patients have a higher likelihood of having suffered from tinnitus before CKD was diagnosed, but we have no data suggesting that tinnitus is a predictor of subsequent CKD. Patients diagnosed with tinnitus may benefit from proactive measures to prevent CKD and detect it early through lifestyle modifications and regular renal function examinations, regardless of CKD-related symptoms.

Effect of N-acetyl-cysteine in prevention of noise-induced hearing loss: a systematic review and meta-analysis of randomized controlled trials.

Introduction: Noise-induced hearing loss is one of the most prevalent causes of hearing impairment and occupational diseases. Although multiple factors lead to noise-induced hearing loss, prevention and protection strategies remain limited. Studies in the past decade have employed antioxidants, especially N-acetyl-cysteine, to prevent noise-induced hearing loss. Therefore, this systematic review and meta-analysis of randomized controlled trials evaluated the effect of N-acetyl-cysteine on the prevention of noise-induced hearing loss. Material and methods: This systematic review and meta-analysis included relevant studies from the Cochrane Library, EMBASE, PubMed, ScienceDirect, Scopus, and Web of Science by using related terms. The study only included randomized controlled trials in meta-analyses and assessed the quality of the identified randomized controlled trials by using the Cochrane Risk of Bias tool. Two authors extracted and calculated data on characteristics and hearing threshold. The results are presented as weighted mean difference (WMD) with 95% confidence interval (CI). Results: This study identified five randomized controlled trials that randomized 1,115 patients into N-acetyl-cysteine and control groups. The meta-analysis evidenced that N-acetyl-cysteine has greater protective effects against hearing threshold shifts than the control in the 0 to 4 kHz (WMD = -3.39, 95% CI: -6.56 to -0.22) and 0 to 6 kHz (MD = -3.49, 95% CI: -6.57 to -0.41) subgroups. Conclusions: The present review and meta-analysis recommends that N-acetyl-cysteine may be considered as an option for protective therapy for noise-induced hearing loss. Nonetheless, larger randomized controlled trials are requisite for further investigation and verification.

Impaired spontaneous secretion as a potential factor in the development of sialolithiasis in the submandibular gland: A preliminary sialoscintigraphic study.

Objectives: The development of sialolithiasis is commonly related to local factors, such as the retrograde migration of foods, bacteria, or foreign bodies from the oral cavity. The association of sialolithiasis and saliva stasis resulting from decreased spontaneous secretion remains largely unexplored. The current study investigated the potential role of impaired spontaneous secretion in association with the formation of submandibular gland calculi. Study Design: A retrospective cohort study. Methods: Between September 2016 and December 2017, 11 patients with unilateral submandibular gland sialolithiasis confirmed with sialendoscopy were assigned to the experimental group. Another 35 patients clinically diagnosed with parotid obstructive sialadenitis were assigned as the control group. The slope changes of the isotope count curve of the unaffected submandibular gland in the experimental group and the bilateral submandibular glands in the control group were calculated and compared to estimate the spontaneous secretion differences. The degree of spontaneous secretion was defined as the slope changes in the steady ascending stage of the scintigraphic exam. Results: The slope decline (degree of spontaneous secretion) on the unaffected side in patients with single-gland submandibular obstructive sialadenitis was significantly lower than that in the control individuals (p = .002). In contrast, the between-group comparison in the unaffected parotid glands revealed no difference in the slope decline. Conclusion: The spontaneous secretion of the submandibular gland in patients with submandibular sialolithiasis was decreased compared to that in patients without submandibular sialolithiasis. This phenomenon might be associated with the development of sialolithiasis. Level of Evidence: 3.

The influence of natural environments on creativity.

This study investigated the effects of different natural environments on attention restoration and creativity. To compare the restorative benefits based on the degrees of perceived naturalness in urban areas, this study categorized environments into three types of perceived naturalness and tested the effect on one's creativity. The urban campus was selected as the study site, representing high-, medium-, and low-perceived naturalness photosets downloaded from Google Street Map images as experimental stimuli. The study invited 100 subjects to take the Abbreviated Torrance Test for Adults (ATTA), which measures creative thinking by viewing the onscreen photosets of the experimental stimuli. In addition, this study asked participants to complete the Perceived Restoration Scale (PRS) questionnaires. The results showed that high- and medium-perceived naturalness in the urban-campus site was superior to low-perceived naturalness in creative performance. In addition, there were significant differences in elaboration and flexibility for different degrees of perceived naturalness. Various degrees of perceived naturalness showed a substantial correlation between PRS scores and ATTA scores. The attention restoration benefits of high- and medium-naturalness environments improve creativity. Our study indicates that viewing natural environments stimulates curiosity and fosters flexibility and imagination, highly natural environments distract our minds from work, and the benefits of attention restoration can improve the uniqueness and diversity of creative ideas. This study provides a reference for creative environmental design and supports further understanding of nature's health and creativity benefits in urban areas.
