The purpose of this study is to examine the work ability of professional dancers working in both of these fields and to analyze influencing factors associated with each work model.

Methods: A partially standardized survey was used to collect sociodemographic and dance-specific data.

Patient-Specific Factors to Differentiate Between Branchial Cleft Cysts and CUP Syndrome: A 10 Year Unicenter Study.

Objectives: Due to its generally-poor prognosis and varied clinical presentation, cervical cancer of unknown primary (CUP) poses particular challenges for clinical and imaging diagnosis. Differential diagnoses of CUP syndrome may also include lateral cervical cysts. When a benign neck cyst is initially suspected, squamous cell carcinoma is often diagnosed after receiving histopathology.

The baseline examinations of the German National Cohort (NAKO): recruitment protocol, response, and weighting.

The German National Cohort (NAKO) is the largest population-based epidemiologic cohort study in Germany and investigates the causes of the most common chronic diseases. Between 2014 and 2019, a total of 1.3 million residents aged 20-69 years from 16 German regions were randomly selected from the general population and invited to participate following a highly standardized recruitment protocol.

[How to identify cystic lateral neck mass from CUP-like lesions: a diagnostic challenge].

A cystic lateral neck mass in adults represents a major challenge, as it can be difficult to distinguish between benign and malignant lesions. The incidence of carcinoma in initially benign treated neck cysts is estimated to be as high as 24%. The objective of this study was to ascertain the malignancy rate of cystic cervical masses and to provide a differentiation of cervical metastases in comparison to benign cervical cysts, utilising current guidelines.

[Short-term quality of life assessment after sinus surgery for chronic rhinosinusitis].

Background: Chronic rhinosinusitis (CRS) has a negative impact on health-related quality of life (HRQoL). Functional endoscopic sinus surgery (FESS) is the treatment of choice for those not responding to medical treatments. To date, the short-term effects of FESS on HRQoL are still unclear.

Normative data for interpreting the SNOT-22.

Objectives: The Sino-Nasal Outcome Test 22 (SNOT-22) is a validated patient-reported outcome instrument to evaluate the health-related quality of life (HRQoL) in patients with chronic rhinosinusitis (CRS). There are no published normative SNOT-22 scores, limiting its interpretation.

Methods: Symptom scores from 1,000 SNOT-22 questionnaires were analysed by principal component analysis (PCA) and exploratory factor analyses.

Comparison of Four Active SARS-CoV-2 Surveillance Strategies in Representative Population Sample Points: Two-Factor Factorial Randomized Controlled Trial.

Background: The COVID-19 pandemic is characterized by rapid increases in infection burden owing to the emergence of new variants with higher transmissibility and immune escape. To date, monitoring the COVID-19 pandemic has mainly relied on passive surveillance, yielding biased epidemiological measures owing to the disproportionate number of undetected asymptomatic cases. Active surveillance could provide accurate estimates of the true prevalence to forecast the evolution of the pandemic, enabling evidence-based decision-making.

[Validity of the German Menière's Disease Patient-Oriented Symptom Severity Index].

Background: The MD POSI is a disease-specific questionnaire to determine the health-related quality of life (HRQoL) of patients with Menière's disease (MD).

Objectives: Validity and reliability of the German translation of the MD POSI.

Material And Methods: Prospective data analysis of a patient group with vertigo (n = 162), which was treated in the otorhinolaryngology of a University Hospital from 2005-2019.

Long-term analysis of prognostic risk factors impacting surgical outcomes in patients with external auditory canal carcinoma.

Background: Malignant neoplasms of the external auditory canal (EAC) are rare. No consensus on management has emerged.

Objective: To determine possible risk factors influencing tumorgenesis and prognosis of EAC carcinoma.

Can patient-reported outcomes and inflammatory markers define endotype 2 in chronic rhinosinusitis without nasal polyps?

Background: Chronic rhinosinusitis (CRS) is a heterogeneous disease at the clinical phenotype level (without nasal polyp [CRSsNP] vs with nasal polyp [CRSwNP]) and at the underlying inflammatory endotype level (type 2 vs non-type 2). Whether the endotype is associated with clinical presentation in patients with CRSsNP has yet to be explored in detail.

Objective: To identify associations between endotypes and their clinical significance in patients with CRSsNP based on tissue interleukin-5 levels.

Does a tonsillectomy indicated according to the German S2k guideline affect short-term quality of life in adults?

Background: Tonsillectomy (TE) for recurrent tonsillitis (RT) is one of the most common surgical interventions. Since 2015, the indication criteria for TE have become much stricter (German S2k guideline). Patient-reported outcome measures (PROMs) of short-term quality of life (QoL) after TE have not yet been investigated.

Long-term outcomes and quality of life following parotidectomy for benign disease.

Objective: Parotidectomy worsens quality of life (QoL) in the short-term, but the long-term impact is unknown. In this study, we analysed the long-term effects of parotidectomy on QoL.

Methods: In this prospective long-term follow-up study, participants were divided into three groups: short-term (ST) follow-up of six weeks, long-term (LT) follow-up of 13 years and short- and long-term (SLT) follow-up.

Statistical Analysis in the German National Cohort (NAKO) - Specific Aspects and General Recommendations.

The German National Cohort (NAKO) is an ongoing, prospective multicenter cohort study, which started recruitment in 2014 and includes more than 205,000 women and men aged 19-74 years. The study data will be available to the global research community for analyses. Although the ultimate decision about the analytic methods will be made by the respective investigator, in this paper we provide the basis for a harmonized approach to the statistical analyses in the NAKO.

Monitoring the health and healthcare provision for refugees in collective accommodation centres: Results of the population-based survey RESPOND.

To date, the integration of refugees in German health surveys is insufficient. The survey RESPOND (Improving regional health system responses to the challenges of forced migration) aimed to collect valid epidemiological data on refugee health status and healthcare provision. The core elements of the survey consisted of a population-based sampling procedure in Baden-Württemberg, multilingual questionnaires and a face-to-face approach of recruitment and data collection in collective accommodation centres with multilingual field teams.

[Validity and reliability of the Nijmegen Cochlear Implant Questionnaire in German].

Background: The Nijmegen Cochlear Implant Questionnaire (NCIQ) is a disease-specific questionnaire to determine the health-related quality of life (HRQoL) of patients before and after cochlear implantation.

Objective: This study aimed to assess the validity and reliability of the German translation of the NCIQ.

Materials And Methods: A prospective study was performed in 100 postlingually deaf or severely hearing-impaired patients.

Effectiveness and cost-effectiveness of four different strategies for SARS-CoV-2 surveillance in the general population (CoV-Surv Study): study protocol for a two-factorial randomized controlled multi-arm trial with cluster sampling.

Background: To achieve higher effectiveness in population-based SARS-CoV-2 surveillance and to reliably predict the course of an outbreak, screening, and monitoring of infected individuals without major symptoms (about 40% of the population) will be necessary. While current testing capacities are also used to identify such asymptomatic cases, this rather passive approach is not suitable in generating reliable population-based estimates of the prevalence of asymptomatic carriers to allow any dependable predictions on the course of the pandemic.

Methods: This trial implements a two-factorial, randomized, controlled, multi-arm, prospective, interventional, single-blinded design with cluster sampling and four study arms, each representing a different SARS-CoV-2 testing and surveillance strategy based on individuals' self-collection of saliva samples which are then sent to and analyzed by a laboratory.

How to predict the outcome of septorhinoplasty? A normative study of ROE and FROI-17 scores.

Objective: Normative values of patient-reported outcome instruments are needed to identify good candidates for rhinoplasty. Rhinoplasty Outcome Evaluation (ROE) and Functional Rhinoplasty Outcome Inventory-17 (FROI-17) are disease-specific questionnaires that evaluate quality of life in patients undergoing rhinoplasty.

Methods: The reference cohort contained 1,000 participants, selected from a non-probability panel.

Prospective study on health-related quality of life in patients before and after cochlear implantation.

Purpose: Assessing cochlear implant (CI)-associated patient outcomes is a focus of implant research. Most studies have analyzed outcomes retrospectively with low patient numbers and few measurement time points. In addition, standardized CI-specific health-related quality of life (HRQoL) instruments have not been used.

Effectiveness and cost-effectiveness of four different strategies for SARS-CoV-2 surveillance in the general population (CoV-Surv Study): a structured summary of a study protocol for a cluster-randomised, two-factorial controlled trial.

Objectives: In this cluster-randomised controlled study (CoV-Surv Study), four different "active" SARS-CoV-2 testing strategies for general population surveillance are evaluated for their effectiveness in determining and predicting the prevalence of SARS-CoV-2 infections in a given population. In addition, the costs and cost-effectiveness of the four surveillance strategies will be assessed. Further, this trial is supplemented by a qualitative component to determine the acceptability of each strategy.
