The aim of this study is to identify risk factors for residual dizziness in benign paroxysmal positional vertigo patients after repositioning manoeuvres and explore the mediation role of lipid indicators.

In all, 110 benign paroxysmal positional vertigo patients treated from January 2019 to February 2022 were studied. Data on demographics, diseases, behaviours, and lipids were collected. Multivariate logistic regression assessed risk factors, and mediation analyses explored effects via lipid indicators. Odds ratios and 95 per cent confidence intervals are reported.

Differences between groups with and without residual dizziness included limb weakness, hypertension, nausea, arteriosclerosis, medication, dizziness handicap inventory scores, hospital anxiety and depression scale scores, and lipid distributions (p < 0.05). Significant risk factors were sleep disorders, medication, hypertension, triglycerides, and total cholesterol (p < 0.05). Total cholesterol mediated 9.1 per cent of the effect of sleep disorders on residual dizziness.

Managing lipid levels and sleep disorders is crucial in treating residual dizziness in benign paroxysmal positional vertigo patients after repositioning.

To appraise clinical practice guidelines for anaplastic thyroid carcinoma treatment and management using the Appraisal of Guidelines for Research and Evaluation II tool.

A literature search was performed using MEDLINE/PubMed, Embase, Scopus, Cochrane, and Google Scholar. Four reviewers evaluated clinical practice guidelines utilising Appraisal of Guidelines for Research and Evaluation II, with domain scores requiring a threshold of greater than 60 per cent. Inter-reviewer agreement was evaluated using intraclass correlation coefficients.

Twelve clinical practice guidelines were evaluated after application of inclusion and exclusion criteria. There were two “high-”, four “average-”, and six “low-” quality clinical practice guidelines. The domains with the highest scores were “clarity of presentation” (69.44 ± 16.75) and “scope and purpose” (68.87 ± 20.88), while “applicability” (7.12 ± 6.17) and “rigor of development” (50.26 ± 20.77) had the lowest scores. Intraclass correlation coefficients showed a high level of inter-reviewer agreement (0.689–0.924; good–excellent).

These results showcased wide variability in quality amongst guidelines for the treatment and management of anaplastic thyroid carcinoma. These findings necessitate greater standardisation among clinical practice guidelines and greater focus on the applicability of recommended practices.

Vestibular migraine is a newly recognised and debilitating condition. This article aims to provide an overview of what is known of vestibular migraine, delineating its diagnostic criteria and presenting some initial management strategies to aid ENT professionals in delivering optimal care when patients first present to the otolaryngology clinic.

Although traditionally underdiagnosed, there are now clearly defined diagnostic criteria to aid accurate diagnosis of vestibular migraine.

A detailed history and clinical examination are the cornerstone of the diagnostic process, but supportive evidence is required from appropriate audio-vestibular tests and imaging.

This is a unique condition that commonly initially presents to ENT. This article provides a summary of diagnostic and management strategies to facilitate early diagnosis and first-line treatment that can be employed in general ENT settings, which may be particularly useful given the limited availability of specialist audio-vestibular medicine and neuro-otology services.

Evidence development for medical devices is often focused on satisfying regulatory requirements with the result that health professional and payer expectations may not be met, despite considerable investment in clinical trials. Early engagement with payers and health professionals could allow companies to understand these expectations and reflect them in clinical study design, increasing chances of positive coverage determination and adoption into clinical practice.

An example of early engagement through the EXCITE International model using an early technology review (ETR) is described which includes engagement with payers and health professionals to better inform companies to develop data that meet their expectations. ETR is based on an early evidence review, a framework of expectations that guides the process and identified gaps in evidence. The first fourteen ETRs were reviewed for examples of advice to companies that provided additional information from payers and health professionals that was thought likely to impact on downstream outcomes or strategic direction. Given that limitations were imposed by confidentiality, examples were genericized.

Advice through early engagement can inform evidence development that coincides with expectations of payers and health professionals through a structured, objective, evidence-based approach. This could reduce the risk of business-related adverse outcomes such as failure to secure a positive coverage determination and/or acceptance by expert health professionals.

Early engagement with key stakeholders exemplified by the ETR approach offers an alternative to the current approach of focusing on regulatory expectations. This could reduce the time to reimbursement and clinical adoption and benefit patient outcomes and/or health system efficiencies.

It was aimed to explore the relationship between evidence-based medicine (EBM) training and medical students’ views on traditional, complementary, and alternative medicine (TCAM) and their views on conspiracies about COVID-19.

Medical students constitute the future workforce of primary health care services. The relationship between EBM training and their views on conspiracies about COVID-19 is critical to explore for providing a better primary health care. The relationship EBM training and medical students’ views on TCAM is also important in this regard.

This is a cross-sectional study. Turkish medical students were surveyed about EBM training, TCAM, and COVID-19 conspiracies. The electronic survey form consisted of five parts: Demographic characteristics, views and self-perceived knowledge about TCAM and the methods, views on the origin of SARS-COV-2, participation in EBM training, and views on TCAM training. A total of 49 medical schools provided response. Along with descriptive statistics, Chi-square test was utilized.

Among 2577 participants, 24.0% of them believed SARS-COV-2 was artificially designed. The students who have participated in EBM training via both lecture and small group discussions have a less positive view on TCAM than both the students who have not participated in any EBM training (p < 0.05) and the students who participated in only-lectures (p < 0.05). There was a significant association between EBM training and whether believing COVID-19 (SARS-COV-2) has been designed purposefully by some people or it has emerged naturally χ2 (1) = 17.21 p < 0.001. The odds of thinking COVID-19 emerged naturally was 1.85 times higher (95% CI: 1.38-2.47) if the students have participated in EBM training via both lectures and small group discussions than if they have not participated in any EBM training. EBM training affects medical students in terms of beliefs on COVID-19 conspiracies.

To analyse the comparative clinical outcomes and clinicopathological significance of vocal fold leukoplakia lesions treated by appearance classification and traditional methods.

A total of 1442 vocal fold leukoplakia patients were enrolled. Group A patients were treated according to appearance classification and Group B patients were treated according to traditional methods.

In Group A, 24.4, 14.9 and 60.6 per cent of patients had grade I, II and III dysplasia, respectively. Grade I dysplasia (63.4 per cent) was more than twice as frequent in Group B patients than in Group A patients, while grade II dysplasia (20.4 per cent) and grade III dysplasia (16.2 per cent) were significantly less frequent in Group B patients than in Group A patients (p = 0.000). There was a significant correlation between vocal fold leukoplakia appearance and the degree of dysplasia (p = 0.000). The recurrence and malignant transformation rates (17.6 and 31 per cent, respectively) in Group B were significantly greater than those in Group A (10.8 and 25.9 per cent, respectively) (p = 0.000).

Vocal fold leukoplakia appearance classification is useful for guiding treatment decision-making and could help to improve therapeutic accuracy.

A retrospective cross-sectional analysis was conducted of the US Food and Drug Administration's MAUDE (Manufacturer and User Facility Device Experience) database, to evaluate the complication profile of cochlear implantation according to manufacturer.

A review of the MAUDE database was conducted from 1 January 2010 to 31 December 2020. Complications, including infection, extrusion, facial nerve stimulation, meningitis and cerebrospinal fluid leak, were identified using key word searches. The categorised data were analysed using a chi-square test to determine a difference in global complication incidence between three major cochlear implant manufacturers: manufacturer A (Cochlear Limited), manufacturer B (Med-El) and manufacturer C (Advanced Bionics).

A total of 31 857 adverse events were analysed. Implants of manufacturer C were associated with a statistically higher rate of infection (0.97 per cent), cerebrospinal fluid leak (0.07 per cent), extrusion (0.44 per cent) and facial nerve stimulation (0.11 per cent). Implants of manufacturer B were associated with a statistically higher rate of meningitis (0.07 per cent).

Consideration of patient risk factors along with cochlear implant manufacturers can heighten awareness of cochlear implant complications pre-operatively, intra-operatively and post-operatively.

The aim of this systematic review was to collect evidence and recommendations for the applicability of the concept of evidence-based policy making (EBPM) during the coronavirus disease 2019 (COVID-19) pandemic and to discuss the implementation of this concept from a medical science perspective.

This study was performed according to the guidelines, checklist, and flow diagram of Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020. An electronic literature search was conducted on September 20, 2022 using PubMed, Web of Science, Cochrane Library, and CINAHL databases with the following search terms: “evidence based policy making” and “infectious disease.” Study eligibility assessment was performed based on the flow diagram of PRISMA 2020, and risk of bias assessment was performed using The Critical Appraisal Skills Program.

Eleven eligible articles were included in this review and divided into three groups as follows: early, middle, and late stages of the COVID-19 pandemic. Basics of COVID-19 control were suggested in the early stage. The articles published in the middle stage discussed the importance of the collection and analysis of evidence of COVID-19 from around the world for the establishment of EBPM in the COVID-19 pandemic. The articles published in the late stage discussed the collection of large amounts of high-quality data and the development of methods to analyze them, as well as emerging issues related to the COVID-19 pandemic.

This study revealed that the concept of EBPM applicable to emerging infectious disease pandemics changed between the early, middle, and late stages of the pandemic. The concept of EBPM will play an important role in medicine in the future.
