Abstract
With geroscience research evolving at a fast pace, the need arises for human randomized controlled trials to assess the efficacy of geroprotective interventions to prevent age-related adverse outcomes, disease, and mortality in normative aging cohorts. However, to confirm efficacy requires a long-term and costly approach as time to the event of morbidity and mortality can be decades. While this could be circumvented using sensitive biomarkers of aging, current molecular, physiological, and digital endpoints require further validation. In this review, we discuss how collecting real-world evidence (RWE) by obtaining health data that is amenable for collection from large heterogeneous populations in a real-world setting can help speed up validation of geroprotective interventions. Further, we propose inclusion of quality of life (QoL) data as a biomarker of aging and candidate endpoint for geroscience clinical trials to aid in distinguishing healthy from unhealthy aging. We highlight how QoL assays can aid in accelerating data collection in studies gathering RWE on the geroprotective effects of repurposed drugs to support utilization within healthy longevity medicine. Finally, we summarize key metrics to consider when implementing QoL assays in studies, and present the short-form 36 (SF-36) as the most well-suited candidate endpoint.

Abstract
INTRODUCTION Resective epilepsy surgery is often seen as a last resort when treating drug-resistant epilepsy. Positive results on quality of life (QoL) and economic benefits after surgery argue for a less restrictive attitude towards epilepsy surgery for drug-resistant epilepsy. QoL and economic benefits are country-dependent. The objective of the Resective Epilepsy Surgery, QUality of life and Economic evaluation (RESQUE) trial is to evaluate the change in QoL before and after epilepsy surgery in Dutch people with drug-resistant epilepsy. The results will form part of an economic evaluation of epilepsy surgery in people with epilepsy (PWE) in The Netherlands. METHODS AND ANALYSIS A longitudinal prospective multicentre cohort study involving 100 PWE undergoing epilepsy surgery between 2019 and 2025 is being performed in three Dutch academic hospitals. Excluded are PWE who have a lower level of intelligence (TIQ<70) or who do not master the Dutch language. Before surgery and 3, 6, 12 and 24 months after surgery, PWE receive validated online questionnaires (QOLIE-31, EQ-5D, iMCQ and iPCQ) on QoL, cost of care, expectations and satisfaction. Primary outcome is the change in QoL. Secondary outcomes are change in generic QoL, seizure reduction (International League Against Epilepsy Outcome Classification), medical consumption, productivity, the correlation between QoL and seizure reduction and expectation of and satisfaction with the surgery. ETHICS AND DISSEMINATION The study design has been approved by the Medical Ethics Review Committee (METC) of Maastricht UMC+ (2019-1134) and the Amsterdam UMC (vu). At the time of writing, UMC Utrecht is in the process of considering approval. The study will be conducted according to the Dutch Medical Research Involving Human Subjects Act and the Declaration of Helsinki. The results will be publicly disclosed and submitted for publication in international peer-reviewed scientific journals. There is no veto on publication by the involved parties. TRIAL REGISTRATION NL8278; Pre-results.

Quality of Life After Combined Endonasal Endoscopic Odontoidectomy and Posterior Suboccipital Decompression and Fusion. World Neurosurg 2018; 116:e571-e576.

Abstract
BACKGROUND Basilar invagination can result from systemic diseases that can weaken structural integrity of the craniocervical junction. Definitive treatment often requires ventral decompression and posterior decompression and fusion. Endonasal odontoidectomy is a relatively new minimal access procedure; quality of life (QOL) after this procedure has not been reported. METHODS We reviewed a consecutive database of endonasal odontoidectomy cases and identified patients having posterior decompression and fusion. Two QOL questionnaires were administered postoperatively: Sino-Nasal Outcome Test and 36-Item Short Form Survey. Comparisons with other endonasal or Chiari procedures were performed. RESULTS The study comprised 14 patients; 79% had Chiari malformation in addition to basilar invagination. Mean follow-up was 17.2 months. Symptomatic improvement occurred in 78.6% after surgery. Average postoperative Sino-Nasal Outcome Test scores were 39.2 ± 17.93, with worst scores in areas related to fatigue and sleep patterns but not nasal function. 36-Item Short Form Survey scores were lower in areas of physical function and general health but better for emotional health and pain. Compared with patients undergoing Chiari malformation surgery without endonasal odontoid resection or fusion, patients undergoing odontoidectomy had higher QOL in areas of role emotional, emotional well-being, and pain but worse QOL in general health and role physical. CONCLUSIONS Patients undergoing posterior decompression and fusion with endonasal odontoidectomy do well after surgery with respect to nasal function and emotional health. Patients who also have severe basilar invagination associated with systemic diseases demonstrate reduced QOL after surgery in areas of physical function and sleep leading to fatigue, irritability, and concentration difficulty, likely related to their systemic disease.

Abstract
OBJECT Endoscopic skull base surgery (ESBS) is a minimal-access technique that provides an alternative to traditional approaches. Patient-reported outcomes are becoming increasingly important in measuring the success of surgical interventions. Endoscopic skull base surgery may lead to improvements in quality of life (QOL) since natural orifices are used to reach the pathology; however, sinonasal QOL may be negatively affected. The purpose of this study was to assess the impact of ESBS on both site-specific QOL, using the Anterior Skull Base Questionnaire (ASBQ), and sinonasal-related QOL, using the Sino-Nasal Outcome Test (SNOT-22). METHODS Consecutive patients from a tertiary referral center who were undergoing ESBS were prospectively enrolled in this study. All patients completed the ASBQ and SNOT-22 preoperatively as well as at regular intervals after ESBS. RESULTS Sixty-six patients were included in the study, and 57.6% of them had pituitary adenoma. There was no significant decline or improvement in the ASBQ-measured QOL at 3 and 6 weeks after ESBS, but there were significant improvements at 12 weeks and 6 months postoperatively (p < 0.05). Improvements were noted in all but one ASBQ subdomain at 12 weeks and 6 months postsurgery (p < 0.05). Preoperative QOL was significantly worse in patients who had undergone revision surgery and significantly improved postoperatively in patients who underwent gross-total resection (p < 0.05). Scores on the SNOT-22 worsened at 3 weeks postoperatively and returned to baseline thereafter. The presence of a nasoseptal flap or a graft-donor site did not contribute to a decreased QOL. CONCLUSIONS Endoscopic skull base surgery is associated with an improvement in postoperative site-specific QOL as compared with the preoperative QOL. Short-term improvements are greater if gross-total resection is achieved. Sinonasal QOL transiently declines and then returns to preoperative baseline levels. Endoscopic skull base surgery is a valuable tool in the neurosurgical management of anterior skull base pathology, leading to improvements in site-specific QOL.

Abstract
OBJECTIVES/HYPOTHESIS Eustachian tube dysfunction (ETD) is a common condition that is associated with otologic and rhinologic symptoms. The complete assessment of ETD is limited without a valid symptom score. We developed and conducted initial validation of the seven-item Eustachian Tube Dysfunction Questionnaire (ETDQ-7), a disease-specific instrument to assess symptoms with respect to ETD. STUDY DESIGN Validation study. METHODS The ETDQ-7 was developed using standard survey methodology. The ETDQ-7 was completed by a group of 50 consecutive adult patients diagnosed with ETD and 25 non-ETD patients who served as a control group. Tympanometry was used as a criterion standard to distinguish the two groups. A subset of respondents repeated the ETDQ-7 at a time point 4 weeks later. RESULTS Content validity for the ETDQ-7 was established by focus group and review of the literature. Reliability testing indicated acceptable internal consistency for the entire instrument (Cronbach α = .71). The test-retest reliability indicated good correlation between the two questionnaires completed by the same patient 4 weeks apart (r = 0.78). The ETDQ-7 was able to discriminate between patients with ETD and those without (P < .001), indicating excellent discriminant validity. CONCLUSIONS The ETDQ-7 is a valid and reliable symptom score for use in adult patients with ETD that may facilitate clinical practice by highlighting the impact of ETD. Further testing is needed to determine its usefulness in assessing treatment response.

Abstract
Food allergy has become an emerging health problem in Western societies. Although food allergy is characterized by a relatively low mortality and an almost continual absence of physical symptoms, food allergic patients are continually confronted with the possibility of potentially severe reactions and the necessity of dietary vigilance. Health-related quality of life (HRQL) may be the only meaningful outcome measure available for food allergy measuring this continuous burden. HRQL may be measured with generic or disease-specific instruments. Generic instruments may be relatively unresponsive to differences or changes in health status, whereas disease-specific instruments are generally more sensitive for relatively subtle problems related to a particular illness. Recently, a number of disease-specific questionnaires have become available to measure the HRQL of food allergic patients. An important area for further research is the interpretation of the outcome of HRQL measures. In this respect, the minimal clinically important difference (MCID) is of special interest. In combination with the numbers needed to treat (NNT), this may give an ultimate insight into the clinical relevance of an intervention. Since there is still no cure for food allergy, the only available treatment is strict avoidance of the culprit food and provision of emergency treatment. The double-blind placebo-controlled food challenge (DBPCFC) is considered to be the gold standard for diagnosing food allergy. A number of studies have investigated the perceptions of parents whose children underwent a DBPCFC. In contrast to the parental perception, there is much currently still unknown about the effects of undergoing a DBPCFC in the perceptions of patients. In addition to the research on MCID and NNT of food allergy HRQL questionnaires, further research should focus on deriving quality-adjusted life years (QALYs) from food allergy HRQL questionnaires and the application of food allergy HRQL questionnaires at the individual patient level in clinical practice.
