BACKGROUND & OBJECTIVE: It has been suggested that prenatal vitamin D plays a role in the development of childhood asthma and wheeze. Several systematic reviews have been conducted, but the results are inconsistent, and the methodological quality has not been studied. Therefore, the objective of this umbrella review was to assess the internal validity of the evidence base and the evidence for an association between prenatal vitamin D and asthma or wheezing in the offspring.

METHODS: We searched the electronic databases Embase, PubMed, and Cochrane Library for studies on prenatal vitamin D using search words such as vitamin D, 25-hydroxyvitamin D, calcidiol, fetal, and neonatal. The search was conducted in June 2020, and the databases were searched from their date of establishment. We included systematic reviews and/or meta-analyses of experimental and observational studies assessing the association between prenatal vitamin D or asthma and wheeze. We excluded narrative reviews, commentaries, and other umbrella reviews. The methodological quality of systematic reviews was assessed using AMSTAR 2 tool. PROSPERO reg. no. CRD42020151329.

RESULTS: We identified 22 eligible systematic reviews (17 on asthma and 20 on wheeze). Using the AMSTAR 2 quality assessment tool, the methodological quality was rated as critically low in 21 out of 22 systematic reviews, suggesting that previous reviews and meta-analyses did not provide accurate and comprehensive summaries of the included studies and that conclusions reached were potentially flawed. The majority of the included reviews reported that prenatal vitamin D reduces the risk of wheeze in the offspring.

CONCLUSION: Prior to informing public guidelines, high-quality systematic reviews of the current evidence are greatly warranted.

C-reactive protein (CRP) has prognostic value in hospitalized patients with COVID-19; the importance of CRP in pre-hospitalized patients remains to be tested. Methods: Individuals with symptoms of COVID-19 had a SARS-CoV-2 PCR oropharyngeal swab test, and a measurement of CRP was performed at baseline, with an upper reference range of 10 mg/L. After 28 days, information about possible admissions, oxygen treatments, transfers to the ICU, or deaths was obtained from the patient files. Using logistic regression, the prognostic value of the CRP and SARS-CoV-2 test results was evaluated. Results: Among the 1006 patients included, the SARS-CoV-2 PCR test was positive in 59, and the CRP level was elevated (>10 mg/L) in 131. In total, 59 patients were hospitalized, only 3 of whom were SARS-CoV-2 positive, with elevated CRP (n = 2) and normal CRP (n = 1). The probability of being hospitalized with elevated CRP was 4.21 (95%CI 2.38-7.43, p < 0.0001), while the probability of being hospitalized with SARS-CoV-2 positivity alone was 0.85 (95%CI 0.26-2.81, p = 0.79). Conclusions: CRP is not a reliable predictor for the course of SARS-CoV-2 infection in pre-hospitalized patients. CRP, while not a SARS-CoV-2 positive test, had prognostic value in the total population of patients presenting with COVID-19-related symptoms.

OBJECTIVE: To standardize and assess the reliability of ultrasonographic assessment of inflammatory and structural lesions in patients with hand osteoarthritis (OA).

METHODS: The Outcome Measures in Rheumatology (OMERACT) Ultrasound Working Group selected synovial hypertrophy (SH), joint effusion (JE), and power Doppler (PD) signals as the main inflammatory lesions in hand OA, and suggested osteophytes in the scapho-trapezio-trapezoid (STT) and cartilage defects in the proximal interphalangeal (PIP) joints as novel additions to previous structural scoring systems. A complementary imaging atlas provided detailed examples of the scores. A reliability exercise of static images was performed for the inflammatory features, followed by a patient-based exercise with six sonographers testing inflammatory and structural features in twelve hand OA patients. We used Cohen's kappa (κ) for intra-reader and Light's κ for inter-reader reliability for all features except PD, in which Prevalence-Adjusted Bias-Adjusted Kappa (PABAK) was applied. Percentage agreement was also assessed.

RESULTS: The web-based reliability exercise demonstrated substantial intra- and inter-reader reliability for all inflammatory features (κ>0.64). In the patient-based exercise, intra- and inter-reader reliability varied: SH κ=0.73 and 0.45; JE κ=0.70 and 0.55; PD PABAK=0.90 and 0.88; PIP cartilage κ=0.56 and 0.45; STT osteophytes κ=0.62 and 0.36. Percentage close agreement was high for all features (>85%).

CONCLUSION: With ultrasound, substantial to excellent intra-reader reliability was found for inflammatory features of hand OA. Inter-reader reliability was moderate, but overall high close agreement between readers suggest that better reliability is achievable after further training. Assessment of osteophytes in the STT joint and cartilage in the PIP joints achieved less good reliability and the latter is not endorsed.

The Danish Health Authority develops clinical practice guidelines to support clinical decision-making based on the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system and prioritizes using Cochrane reviews. The objective of this study was to explore the usefulness of Cochrane reviews as a source of evidence in the development of clinical recommendations. Evidence-based recommendations in guidelines published by the Danish Health Authority between 2014 and 2021 were reviewed. For each recommendation, it was noted if and how Cochrane reviews were utilized. In total, 374 evidence-based recommendations and 211 expert consensus recommendations were published between 2014 and 2021. Of the 374 evidence-based recommendations, 106 included evidence from Cochrane reviews. In 28 recommendations, all critical and important outcomes included evidence from Cochrane reviews. In 36 recommendations, a minimum of all critical outcomes included evidence from Cochrane reviews, but not all important outcomes. In 33 recommendations, some but not all critical outcomes included evidence from Cochrane reviews. Finally, in nine recommendations, some of the important outcomes included evidence from Cochrane reviews. In almost one-third of the evidence-based recommendations, Cochrane reviews were used to inform clinical recommendations. This evaluation should inform future evaluations of Cochrane review uptake in clinical practice guidelines concerning outcomes important for clinical decision-making.

OBJECTIVE: We aim to identify and prioritise rehabilitation interventions to strengthen participation in everyday life for young adult cancer survivors (YACS) between 18 and 39 years, involving the perspectives of YACS and relevant stakeholders.

METHODS: A group concept mapping study was conducted in Denmark from 2019 to 2020. Online, participants generated and sorted ideas followed by rating their importance. Multidimensional scaling followed by hierarchical cluster analyses were applied to generate a cluster rating map of the prioritised interventions, which participants validated at a face-to-face meeting. Finally, a concluding conceptual model of prioritised rehabilitation intervention for YACS was developed.

RESULTS: The study involved 25 YACS, three family members and 31 professionals working with YACS. The conceptual model included 149 ideas classified into eight intervention components created by the participants: (1) Treatment and possibilities within the social and healthcare system, (2) Rights and Finance, (3) Education and Work, (4) Psychological problems, (5) Body and Everyday Life, (6) Peer-to-peer, (7) Sexuality and Relationships and (8) Family and Friends. All components were rated equally important, whereby 17 ideas across the eight components were rated very important.

CONCLUSION: This study indicates that rehabilitation of YACS should be composed of eight equally important intervention components requiring an interdisciplinary approach.
