Autophagy plays a complicated role in the occurrence and development of cancer. Beclin 1 is a significant autophagy-related protein that plays an essential role in tumorigenesis, but its expression is controversial in melanoma. In this meta-analysis, we searched seven studies involving 638 melanoma patients. PubMed, Web o f Science, Google Scholar, Elsevier, and Chinese National Knowledge Infrastructure were used for literature retrieval. The I2 index was used to assess heterogeneity. The expression of Beclin 1 in the primary melanoma group was significantly lower than the non-tumor group tissues (P 0.05). Different expression intensities of Beclin 1 did not affect the overall survival and disease-free survival of melanoma patients. This study showed a trend of low expression of Beclin 1 in melanoma; patients with low expression of Beclin 1 were prone to the possibility of distant metastasis. The inconsistent profile of Beclin 1 expression in the prognosis of melanoma patients warrants further clinical investigation.

A Novel Two Surgeons Approach to Bronchial Foreign Body Removal by Optical Instruments- An 11 Years Institutional Experience

xlomafota13 shared this article with you from Inoreader

Abstract

A potentially life-threatening emergency in ENT practice is the aspiration of tracheobronchial foreign body. This commonly affects young children and requires early extraction. Successful removal provides immediate relief. However procedural complications can cause devastating morbidity like anoxic encephalopathy or instant death. The aim of this study is to describe the experience in our institution with two surgeons approach for removal of tracheobronchial foreign bodies by telescope and optical forceps. This is an observational study from the period of March 2010 to April 2021 in which 96 patients (59 males, 37 females; age range 3 months to 15 years) were diagnosed with foreign body aspiration. In all cases rigid bronchoscopy and FB removal under general anaesthesia was performed using the two surgeons technique. This technique was instituted once Storz make paediatric telescope (2.9 mm diameter 36 cm length), optical grasping forceps and optical suction were procured in March 2010. Aspirated material was inorganic or organic with varying location in right main bronchus, left main bronchus or the trachea. We highlight the OT setup, surgical algorithm and the advantages of this technique. Visual and tactile coordination between the two surgeons being the crux of this procedure; allows hands on mentoring of the next generation of budding surgeons in a real-life scenario without compromising patient safety.

Effect of Efferent Stimulation on the Differential Sensitivity in Individuals with Normal Hearing

xlomafota13 shared this article with you from Inoreader

Abstract

The aim of the article was to compare the conditions of silent and contralateral noise on Differential sensitivity in normal hearing individuals. A total of 40 participants (20 males and 20 females) were enrolled in the study with a mean age of 21.7 years, participants with normal hearing thresholds and no history of middle ear pathology were enrolled for the study. Difference limen tests such as difference limen for intensity (DLI), difference limen for frequency (DLF), and difference limen for time (DLT) were carried out in these 40 individuals in the two conditions of silent and contralateral noise using MATLAB. Statistical analysis was carried out using the SPSS version 25.0 were descriptive and inferential statistics were carried out. Data was normally distributed on the Shapiro–Wilk's test of normality due to which a paired t test was carried out to establish the nature of significance between the silent and contralateral noise condition. Results r eveal the presence of significant difference (P < 0.01) between the groups for DLF and DLT with contralateral noise condition performing better than silent condition for the parameters. However, no significant difference was obtained for DLI. There is a positive effect of the efferent auditory pathway on the Differential sensitivity thus implying that speech perception in noise is improved in the presence of background noise for normal hearing individuals due to this effect. But in case of DLI, the reduced spread of excitation could be the reason why there were no significant differences between silent and contralateral noise condition.

Non‐invasive evaluation of subjective sensitive skin by transcriptomics using mRNA in skin surface lipids

xlomafota13 shared this article with you from Inoreader

Abstract

Sensitive skin is a condition characterized by hypersensitivity to environmental stimuli, and its pathophysiology has not been fully elucidated. Questionnaires based on subjective symptoms, intervention tests, and measuring devices are used to diagnose sensitive skin; however, objective evaluation methods, including biomarkers, remain to be established. This study aimed to investigate the molecular profiles of self-reported sensitive skin, understand its pathophysiology, and explore its biomarkers. Here, we analyzed RNAs in skin surface lipids (SSL-RNAs), which can be obtained non-invasively by wiping the skin surface with an oil-blotting film, to compare the transcriptome profiles between questionnaire-based 'sensitive' (n = 11) and 'non-sensitive' (n = 10) skin participants. Exactly 417 differentially expressed genes in SSL-RNAs from individuals with sensitive skin were identified, of which C-C motif chemokine ligand 17 and interferon-γ pathways were elevated, while 50 olfactory receptor (OR) genes were downregulated. The expression of the detectable 101 OR genes was lower in individuals with sensitive skin compared to that in those with non-sensitive skin and was particularly associated with the subjective sensitivity among skin conditions. The receiver operating characteristic (ROC) curve demonstrated that the mean expression levels of OR genes in SSL-RNAs could discriminate subjective skin sensitivity with an area under the ROC curve of 0.836. SSL-RNA profiles suggest a mild inflammatory state in sensitive skin, and overall OR gene expression could be a potential indicator for sensitive skin.

Cochlear Implantation in Inner Ear Malformations: Considerations Related to Surgical Complications and Communication Skills

Introduction: There are particular challenges in the implantation of malformed cochleae, such as in cases of facial nerve anomalies, cerebrospinal fluid (CSF) leaks, erroneous electrode insertion, or facial stimulation, and the outcomes may differ depending on the severity of the malformation. The aim of this study was to assess the impact of inner ear malformations (IEMs) on surgical complications and outcomes of cochlear implantation. Methods: In order to assess the impact of IEMs on cochlear implant (CI) outcomes, 2 groups of pati ents with similar epidemiological parameters were selected from among 863 patients. Both the study group (patients with an IEM) and control group (patients with a normal inner ear) included 25 patients who received a CI and completed at least 1 year of follow-up. Auditory performance, receptive and expressive language skills, and production and use of speech were evaluated preoperatively and at least 1 year after implantation. Types of surgical complications and rates of revision surgeries were determined in each group. Results: In the study group, the most common malformation was an isolated enlarged vestibular aqueduct (EVA) (44.8%). Overall, the patients with IEMs showed significant improvement in auditory-verbal skills. In general, the patients who had normal cochleae scored significantly better compared to patients with IEMs (p #x3c; 0.05). The complication rate was significantly lower in the control group compared to the study group (p = 0.001), but the rate of revision surgeries did not differ significantly (p = 0.637). Conclusion: It is possible to improve communication skills with CIs in patients with IEMs despite the variations in postoperative performances. Patients with EVA, incomplete partition type 2, and cochlear hypoplasia type 2 were the best performers in terms of auditory-verbal skills. Patients with IEMs scored poorly compared to patients with normal cochleae. CSF leak (gusher or oozing) was the most common complication during surgery, which is highly likely in cases of incomplete partition type 3.
