Stress exacerbates the pathophysiology of major neurodegenerative disorders. In this study, the zebrafish (Danio rerio), the frequently used model for experimental studies of stress and other central nervous system disorders, was used to evaluate the anxiolytic potential of flavonoids, namely silibinin and naringenin on alleviating acute stress-induced anxiety.
A molecular docking study with Molegro Virtual Docker software was done to assess the binding potential of flavonoids on serotonin and dopamine receptors. To determine the bioactivity and investigate the toxicity of the flavonoids, silibinin, and naringenin, brine shrimp lethality assay, and an acute toxicity study was conducted according to Organization for Economic Co-operation and Development (OECD) Test Guideline 203. The effect of silibinin and naringenin was assessed using behavioral tasks such as the novel tank assay and the light-dark test on the zebrafish model of acute stress.
Molecular docking studies showed a higher affinity of silibi day 15
of evaluation as compared to the control group (p < 0.05 and p < 0.001, respectively).
The flavonoids, silibinin, and naringenin were found to mitigate acute stress-induced anxiety, owing to their anxiolytic properties in the zebrafish model and may be explored as the potential therapeutic agents for treating anxiety.

Phyllanthus niruri, a traditional herbal medicine, was found to be hepatoprotective as evidenced by several preclinical and clinical studies. However, to the best of our knowledge, there are no clinical trials available to date to evaluate its efficacy in alcoholic hepatitis.
The present study is a block randomized, double-blind, parallel-arm placebo-controlled trial that was designed to assess the efficacy of P. niruri on the liver and renal function parameters, total oxidant and antioxidant levels in alcoholic hepatitis patients in comparison to placebo over a 4-week period. Patients were screened by CAGE questionnaire, and those with a confirmed diagnosis of mild-moderate alcoholic hepatitis based on laboratory findings and Maddrey's discriminant function score were randomly allocated to treatment and placebo arms. Clinical assessments were done at baseline, 2 weeks, and 4 weeks. A total of 454 patients were screened and 100 eligible patients were recruited for the study, and 71 were analyzed using the modified intention-to-treat approach.
Serum levels of liver and renal function parameters failed to demonstrate significant improvement with P. niruri. However, there was a statistically significant increase in the level of total antioxidants with P. niruri (P = 0.034) with an additional appetite stimulant activity (P = 0.03) in 4 weeks.
A 4-week administration of P. niruri in mild-moderate alcoholic hepatitis patients showed an improvement in the total antioxidant levels with an appetite stimulant activity compared to a placebo.

Dexmedetomidine, although an effective drug for conscious sedation during flexible bronchoscopy, has occasional side effects on the cardiovascular system which need to be addressed.
Patients between 18 and 65 years, requiring diagnostic flexible bronchoscopy, found eligible, after screening, were randomized to either receive 0.75 μg/kg intravenous dexmedetomidine over 10 min or intravenous midazolam 0.035 mg/kg over 1 min. Composite score was used as the primary outcome measure. Additional parameters recorded were Hemodynamic variables, oxygen saturation, Ramsay sedation score, for pain intensity and distress Numerical Rating Scale, number of rescue medication doses, ease of doing bronchoscopy, Visual Analog Scale score for cough and response of the patient 24 h after bronchoscopy.
In each group, 24 patients were enrolled. The composite score was in the ideal category in 24 patients in dexmedetomidine group and 21 in midazolam group, at nasopharynx (P = 0.234). The corresponding values at the level of trachea were 23 and 16 (P = 0.023). In dexmedetomidine group, patient response after 24 h of bronchoscopy showed quality of sedation to be excellent in 0 subjects, good in 13, fair in 9 and poor in 2 and discomfort to be nil in 7, mild 10, moderate in 7 and severe in 0. The corresponding values in midazolam group for quality of sedation were 0, 4, 14, 6, and for discomfort 0, 10, 14, 0. buy Fedratinib The Visual Analog Scale (VAS) for cough revealed a mean score of 0.800 and 1.812 (P = 0.011) during and 2.092 and 3.542 (P = 0.016) 24 h after bronchoscopy in the respective study groups.
Low-dose dexmedetomidine (0.75 μg/kg single dose) appears to provide better patient comfort and equivalent safety profile when compared with midazolam.

Numerous references indicate that the subjectively assessed tonal noise annoyance is higher than that of broadband noise. There are no criteria for the impact of tonal noise in assessing the occupational environment for both indoor areas and workplaces.
The study participants included 50 people who met the audiometric qualification criteria. The research method employed both a questionnaire survey and computer psychological tests checking work performance, attention level, and memory. Four types of generated test signals were developed (filtered noise - A and three signals with tonal components 125, 1600, and 8000 Hz - B, C, and D) at the same sound level A of 55 dB. Test signals C and D were assessed as causing the greatest annoyance and as the loudest.
The results of some tests and the assessment of annoyance and of the volume of test signals containing medium and high frequency tonal components were correlated with the participants' noise sensitivity, determined on the basis of a questionnaire. Although there are no statistically significant differences, it was observed in most cases for signals with C (1600 Hz) and D (8000 Hz) tonal components that the results (mean values or median values) of psychological tests deteriorated with respect to a noise signal without tonal components (A) - a smaller number of calculations, a smaller number of correct responses, more errors made.
These results, combined with those of the questionnaire survey, justify the introduction of the tonality annoyance criterion for workstations where, among other things, focusing one's attention is required.

This study aimed to investigate the association of earphone use with audiologic and psychologic factors.
Korea National Health and Nutrition Examination Survey 2010-2012 data were collected for participants aged ≥12 years old with earphone use ≥1 hour/day. They were matched to a control group for age, sex, income, and education level. The relationship between earphone use and the hearing thresholds of pure-tone audiometry, tinnitus, and psychologic factors such as depression and anxiety, and other quality of life variables was analyzed using multiple logistic regression tests with complex sampling.
Among the participants, 22.9% (449/1955) of earphone users and 18.1% (355/1600) of control participants had tinnitus (P < 0.001). Earphone users showed 1.27-times higher odds for tinnitus (95% confidence interval [CI] = 1.09-1.50, P = 0.003). Moreover, 6.5% (128/1955) of earphone users and 5.0% (97/1600) of control participants had anxiety and depressive symptoms (P = 0.033). Earphone users showed 1.32-times higher odds for anxiety and depressive symptoms (95% CI = 1.14-1.52, P = 0.040). Nevertheless, the hearing thresholds were comparable between earphone users and control participants.
Earphone use was associated with tinnitus and anxiety or depressive symptoms.

Summarize and analyze the current research results of tinnitus-related genes, explore the potential links between the results of each study, and provide reference for subsequent studies.
Collect and sort out the research literature related to tinnitus genes included in PubMed, Web of Science, China National Knowledge Infrastructure, and Wanfang Data Knowledge Service Platform before December 31, 2019. Then the relevant contents of the literature were sorted out and summarized.
Fifty-one articles were finally selected for analysis 31 articles (60.8%) were classified as researches on animal models of tinnitus, and 20 (39.2%) as researches on tinnitus patients. Existing studies have shown that genes related to oxidative stress, inflammatory response, nerve excitation/inhibition, and nerve growth are differentially expressed in tinnitus patients or animal models, and have presented the potential links between genes or proteins in the occurrence and development of tinnitus.
The research on tinnitus-related genes is still in the exploratory stage, and further high-quality research evidence is needed.

For the symptomatic patients, high mortality rate was observed if without timely and optimized management. In this study, we aimed to investigate the predictive and prognostic roles of hematologic and biochemical parameters obtained in the emergency department (ED) for COVID-19 patients. We conducted a retrospective study in a dedicated COVID-19 medical center, recruiting a total of 228 COVID-19 patients with 86 severe and 142 non-severe cases. Both the hematologic and biochemical parameters obtained in the ED upon arrival were analyzed to evaluate the association of the biomarkers with disease severity and prognosis among COVID-19 patients. Among these parameters, neutrophil-to-lymphocyte ratio (NLR), C-reactive protein (CRP), procalcitonin (PCT), lactate dehydrogenase (LDH), ferritin, and D-dimer were significantly higher in the severe group than the non-severe one, whereas the platelet count and lymphocyte-to-monocyte ratio were significantly lower. Receiver operating characteristic curve analysis revealed that the areas under curve of CRP, PCT, LDH, ferritin, D-dimer, and NLR for differentiating the severity of COVID-19 were 0.713, 0.755, 0.763, 0.741, 0.733, and 0.683, respectively, whereas the areas under curve of CRP, PCT, LDH, ferritin, D-dimer, and NLR for differentiating the mortality of COVID-19 were 0.678, 0.744, 0.680, 0.676, 0.755, and 0.572, respectively. Logistic regression analysis revealed that CRP, PCT, LDH, ferritin, D-dimer, and NLR were independent indicators for prediction of severe COVID-19, and LDH and ferritin were independent factors associated with the mortality in COVID-19. In conclusion, higher CRP, PCT, LDH, ferritin, D-dimer, and NLR were associated with severe COVID-19, whereas higher LDH and ferritin were associated with the mortality in COVID-19. These findings could help early risk stratification in the ED and contribute to optimized patient management.
