OBJECTIVE: To compare estimated treatment effects of physical therapy (PT) between patient-reported outcome measures (PROMs) and outcomes measured in other ways.

STUDY DESIGN AND SETTING: We selected randomized trials of PT with both a PROM and a non-PROM included in Cochrane systematic reviews (CSRs). Two reviewers independently extracted data and risk-of-bias assessments. Our primary outcome was the ratio of odds ratios (RORs), used to quantify how effect varies between PROMs and non-PROMs; an ROR > 1 indicates larger effect when assessed by using PROMs. We used REML-methods to estimate associations of trial characteristics with effects and between-trial heterogeneity.

RESULTS: From 90 relevant CSRs, 205 PT trials were included. The summary ROR across all the comparisons was not statistically significant (ROR, 0.88 [95% CI: 0.70-1.12]; P = 0.30); however, the heterogeneity was substantial (I2 = 88.1%). When stratifying non-PROMs further into clearly objective non-PROMs (e.g., biomarkers) and other non-PROMs (e.g., aerobic capacity), the PROMs appeared more favorable than did clearly objective non-PROMs (ROR, 1.92 [95% CI: 0.99-3.72]; P = 0.05).

CONCLUSION: Estimated treatment effects based on PROMs are generally comparable with treatment effects measured in other ways. However, in our study, PROMs indicate a more favorable treatment effect compared with treatment effects based on clearly objective outcomes.

OBJECTIVES: Stroke is associated with a higher risk of occult cancer. We studied the types of occult cancer most often associated with stroke.

MATERIALS AND METHODS: All patients with incident stroke in Denmark 2003-2015 were identified through the Danish Stroke Registry (n = 85 893) and matched 1:10 on age and sex to the Danish background population without history of stroke (n = 858 740). Linking data to the Danish Cancer Registry, we determined the prevalence of occult cancer in stroke defined as the event of previously unknown cancer during a one-year follow-up in the stroke and the background population. We stratified cancers into the 15 most common cancers and into cancers related to and not related to smoking.

RESULTS: Prevalence (per 1000 person-years; stroke/background population) of smoking-related occult cancers (lung, colon, bladder rectum, pancreas, kidney, stomach, and head and neck) was 13.3/8.1 (P < .01) and of cancers not related to smoking (prostate, breast, melanoma, non-Hodgkin lymphoma, ovary, endometrial) it was 6.6/6.2 (P > .05). Among men with stroke prostate (5.8), lung (5.7), and colon cancers (2.9) were most frequent; among women, it was lung (4.7), breast(3.5), and colon cancer(2.8). Among men in the background population, prostate(5.4), lung (3.0), and colon cancers (2.1) were most frequent. Among women, it was breast (3.7), lung(2.1), and colon cancers (1.9).

CONCLUSION: Stroke patients' increased risk of occult cancer was predominantly for smoking-related cancers while there was no higher risk for the most frequent cancers unrelated to smoking, that is, prostate and breast cancers. Lung cancer is the dominant type of occult cancer in stroke.

Use and reporting of outcome measures in randomized trials for anti-neutrophil cytoplasmic antibody-associated vasculitis: a systematic literature review

Monti, S., Quinn, K. A., Christensen, R., Jayne, D., Langford, C., Lanier, G. E., Mahr, A., Pagnoux, C., Viðarsdóttir, M. B., Merkel, P. A. & Tomasson, G., dec. 2020, I: Seminars in Arthritis and Rheumatism. 50, 6, s. 1314-1325 12 s.

Publikation: Bidrag til tidsskriftReviewpeer review

BACKGROUND: A comprehensive review of outcome measures used in randomized controlled trials (RCTs) of ANCA-associated vasculitis (AAV) could advance trial conductance for this disease.

METHODS: A systematic literature review of outcome measures (as specified in methods section as primary and/or secondary outcomes) in RCTs of AAV was conducted. Medline, Cochrane CENTRAL, and ClinicalTrials.gov were searched from inception until April 30, 2019 for RCTs enrolling patients with granulomatosis with polyangiitis and/or microscopic polyangiitis. Outcome measures were organized according to domains (e.g. disease activity) and instruments [e.g. Birmingham Vasculitis Activity Score (BVAS)].

RESULTS: Out of 1101 identified records, 68 RCTs were eligible. Disease activity was an outcome domain collected in 67 (98%) of the RCTs. The BVAS was the most widely used instrument for disease assessment but definitions for remissions and relapse varied for the purpose of primary endpoint definitions. Damage, most often assessed by the Vasculitis Damage Index, was an outcome in 30 (44%) of the RCTs. Mortality was specified as an outcome in 26 (38%) studies. The following outcome domains were assessed: patient-reported outcomes (PROs) in 28 (41%), drug exposure/safety in 58 (85%), and biomarkers [acute phase reactants, ANCA levels] in 24 (35%). Timing for outcome assessment differed substantially, with 3, 6, or 12 months being the most frequent time points.

CONCLUSION: Outcome measures used in trials in AAV commonly included vasculitis-specific tools for disease assessment, but with heterogeneity in endpoint-definitions and timing of assessments. Other core outcomes in AAV, including PROs, and damage measures, are often omitted in AAV trials.

Using betahistine in the treatment of patients with Menière's disease: a meta-analysis with the current randomized-controlled evidence

Devantier, L., Hougaard, D., Händel, M. N., Liviu-Adelin Guldfred, F., Schmidt, J. H., Djurhuus, B. & Callesen, H. E., okt. 2020, I: Acta Oto-Laryngologica. 140, 10, s. 845-853 9 s.

Publikation: Bidrag til tidsskriftReviewpeer review

Background: Betahistine is used worldwide to treat patients with Menière's disease. However, despite it being used for decades, diverging opinions on the effect of betahistine on Menière's symptomatology still exist.Aims: The objective of this systematic review was to provide an overview and rate the certainty of the current evidence base regarding the use of betahistine to treat patients with Menière's disease.Materials and methods: A systematic literature search was conducted in October 2019. The search strategy was subdivided into searches for existing guidelines, systematic reviews and individual randomized controlled trials (RCT) investigating the usage of betahistine as compared to placebo, in patients with Ménière's disease. The primary outcome was the frequency of vertigo attack(s) and occurrence of serious adverse events.Results: We identified three relevant guidelines and three systematic reviews: however, neither included any relevant trials matching our inclusion criteria. An individual search for RCTs identified one trial. The results from this particular trial showed no difference in effects on symptoms following treatment with betahistine.Conclusions and Significance: There is a need for further well-conducted placebo RCTs. Currently, there is still a lack of substantial evidence supporting betahistine as a significant and adequate treatment for patients diagnosed with Menière's disease. Trial registration number: The protocol is registered in PROSPERO. Registration number: CRD42018110127 Accepted 11.10.2018.

Validation of the colostomy impact score in patients ostomized for a benign condition

Kristensen, H. Ø., Krogsgaard, M., Christensen, P. & Thomsen, T., 2 aug. 2020, (E-pub ahead of print) I: Colorectal Disease.

Publikation: Bidrag til tidsskriftTidsskriftartikelForskningpeer review

AIM: The colostomy impact (CI) score is a patient-reported outcome measure assessing reduction in health-related quality of life (HRQL) due to a stoma. The score was originally developed and validated in a cohort of rectal cancer survivors with a permanent colostomy. For the CI score to be applied to patients with a colostomy after surgery for a benign condition it must be validated in this patient group. The aim of this study was to assess construct validity and known groups validity of the CI score in patients with a colostomy after surgery for a benign condition.

METHOD: In a cross-sectional survey among ostomates in the Capital Region of Denmark, patients completed the CI score and the SF-36 v2 questionnaires. Construct validity was assessed by Pearson's correlation coefficients and known groups validity was assessed by t-test when dividing patients into groups of minor or major CI.

RESULTS: The CI score showed a moderate negative correlation with the Physical Component Summary (PCS) of -0.41 and a weak negative correlation with the Mental Component Summary (MCS) of -0.39. The strength of the correlation depended on the underlying condition leading to stoma formation. Differences were significant between the minor and major CI groups in mean PSC and MCS with t-values of 5.32 and 3.86, respectively.

CONCLUSION: The CI score is a valid instrument for assessing stoma-related impact on HRQL regardless of the underlying condition leading to stoma formation, and the CI score discriminates meaningfully between groups with known differences in stoma-related reduced HRQL.

Vascular ultrasound for the diagnosis of giant cell arteritis: a reliability and agreement study based on a standardised training programme

Chrysidis, S., Terslev, L., Christensen, R., Fredberg, U., Larsen, K., Lorenzen, T., Døhn, U. M. & Diamantopoulos, A. P., okt. 2020, I: RMD Open. 6, 3, s. e001337 7 s.

Publikation: Bidrag til tidsskriftTidsskriftartikelForskningpeer review

OBJECTIVE: To evaluate the impact of a standardised training programme including equipment adjustment for experienced musculoskeletal ultrasonographers without previous experience in vascular ultrasound (US) on the reliability of US in the diagnosis of giant cell arteritis (GCA).

METHODS: In this prospective, non-interventional observational cohort study, patients suspected of GCA were evaluated by US by one of five rheumatologists with long-standing experience in musculoskeletal US (>8 years), trained using a standardised training programme including equipment adjustment. Images of cranial and large vessels were subsequently evaluated first by the performing ultrasonographer and thereafter by a blinded external expert (gold standard).

RESULTS: In three Danish centres, 112 patients suspected of GCA were included. According to the external expert, vasculitis changes were seen in 66 patients, in 45 of them with only cranial involvement, in 14 with both cranial and large vessel involvement, while in seven patients isolated large vessel vasculitis was found. The reliability was excellent between the local ultrasonographer and the US expert for the overall GCA diagnosis regarding the diagnosis of cranial and for large vessel GCA, with an interobserver agreement of 95-96%, mean kappa values of 0.88-0.92 (95% CI 0.78 to 0.99). Excellent reliability (mean kappa 0.86-1.00) was also found for the US examination of the individual arteries (temporal, facial, common carotid and axillary).

CONCLUSION: The US training programme resulted in excellent agreement between trainees and an expert in patients suspected of GCA and may thus be applicable for implementation of vascular US in clinical practice.

This study aims to assess the acceptability, adherence, and retention of a feasibility trial on milk fortification with calcium and vitamin D (Ca+VitD) and periodontal therapy (PT) among low income Brazilian pregnant women with periodontitis (IMPROVE trial). This 2 × 2 factorial feasibility trial used a mixed-methods evaluation. In total, 69 pregnant women were randomly allocated to four groups: 1. fortified sachet with Ca+VitD and milk plus early PT (throughout gestation); 2. placebo and milk plus early PT; 3. fortified sachet with Ca+VitD and milk plus late PT after childbirth; 4. placebo and milk plus late PT. Data were collected via questionnaires, field notes, participant flow logs, treatment diary, and focal group discussions. Quantitative and qualitative data were analysed using appropriate descriptive statistics and content analysis, respectively. Eligibility rate (12%) was below the target of 15%, but participation (76.1%) and recruitment rate (2 women/week) exceeded the targets. Retention rate (78.6%) was slightly below the target (80%). Adherence to the PT was significantly higher in the early treatment groups (98.8%) compared to the late treatment groups (29%). All women accepted the random allocation, and baseline groups were balanced. There was no report of adverse events. This multi-component intervention is acceptable, well-tolerated, and feasible among low-risk pregnant women in Brazil.

BACKGROUND: Technological advances in remote monitoring offer new opportunities to quantify body weight patterns in free-living populations. This paper describes body weight fluctuation patterns in response to weekly, holiday (Christmas) and seasonal time periods in a large group of individuals engaged in a weight loss maintenance intervention.

METHODS: Data was collected as part The NoHoW Project which was a pan-European weight loss maintenance trial. Three eligible groups were defined for weekly, holiday and seasonal analyses, resulting in inclusion of 1,421, 1,062 and 1,242 participants, respectively. Relative weight patterns were modelled on a time series following removal of trends and grouped by gender, country, BMI and age.

RESULTS: Within-week fluctuations of 0.35% were observed, characterised by weekend weight gain and weekday reduction which differed between all groups. Over the Christmas period, weight increased by a mean 1.35% and was not fully compensated for in following months, with some differences between countries observed. Seasonal patterns were primarily characterised by the effect of Christmas weight gain and generally not different between groups.

CONCLUSIONS: This evidence may improve current understanding of regular body weight fluctuation patterns and help target future weight management interventions towards periods, and in groups, where weight gain is anticipated.

OBJECTIVES: The overall study aim was to synthesise understandings and experiences regarding the concept of spiritual care (SC). More specifically, to identify, organise and prioritise experiences with the way SC is conceived and practised by professionals in research and the clinic.

DESIGN: Group concept mapping (GCM).

SETTING: The study was conducted within a university setting in Denmark.

PARTICIPANTS: Researchers, students and clinicians working with SC on a daily basis in the clinic and/or through research participated in brainstorming (n=15), sorting (n=15), rating and validation (n=13).

RESULTS: Applying GCM, ideas were identified, organised and prioritised online. A total of 192 unique ideas of SC were identified and organised into six clusters. The results were discussed and interpreted at a validation meeting. Based on input from the validation meeting a conceptual model was developed. The model highlights three overall themes: (1) 'SC as an integral but overlooked aspect of healthcare' containing the two clusters SC as a part of healthcare and perceived significance; (2) 'delivering SC' containing the three clusters quality in attitude and action, relationship and help and support, and finally (3) 'the role of spirituality' containing a single cluster.

CONCLUSION: Because spirituality is predominantly seen as a fundamental aspect of each individual human being, particularly important during suffering, SC should be an integral aspect of healthcare, although it is challenging to handle. SC involves paying attention to patients' values and beliefs, requires adequate skills and is realised in a relationship between healthcare professional and patient founded on trust and confidence.

This review summarises the present knowledge of diagnosing and treating hip joint pain. The results of joint preserving surgery are good in symptomatic patients with hip dysplasia, acetabular retroversion or impingement (cam or pincer) without signs of osteoarthritis. Confirmation of intraarticular pathology as the cause of symptoms is established clinically, and the pathology can in many cases be visualised by a standing, standardised radiograph of the pelvis, which is the basis for admission to the relevant orthopaedic department. We present an algorithm for this. Dysplasia and retroversion can be treated by periacetabular osteotomy and impingement by arthroscopic procedures.
