Urban-rural and socio-economic differences in inhaled corticosteroid treatment for chronic obstructive pulmonary disease: A nationwide register-based cross-sectional study.

Background: Urban-rural disparities within chronic obstructive pulmonary disease (COPD) have been documented in USA, but not in Europe. Inhaled corticosteroids (ICS) are widely used in COPD despite strict recommendations. We aimed to investigate urban-rural and socioeconomic differences in ICS treatment for COPD.

Psychiatric disorders, diagnosed in psychiatric clinics, in patients with back pain: A cohort study.

The aim of this study was to evaluate whether patients with a non-specific back pain disorder are more likely to be diagnosed with a psychiatric disorder than patients with a specific back pain disorder (such as a herniated disc or inflammatory back disorder). This was a retrospective cohort study using Danish registries. Our study population included 24,518 patients younger than 61 years and 12,274 patients older than 61 years.

Surgery rates for lumbar spinal stenosis in Denmark between 2002 and 2018: a registry-based study of 43,454 patients.

Background And Purpose: Over the last decades, many countries have shown increased surgery rates for lumbar spinal stenosis (LSS), but little information is available from Denmark. We describe the development in diagnosis and surgery of LSS in Denmark between 2002 and 2018.

Patients And Methods: We collected diagnostic ICD10-codes and surgical procedure codes from private and public hospitals in Denmark from the Danish National Patient Register.

Using fecal immunochemical test values below conventional cut-off to individualize colorectal cancer screening.

Of the participants in the Danish screening program, 89.9 % to 92.5 % have fecal immunochemical test (FIT) values < 10 μg/g feces (equivalent to 50 ng hemoglobin/mL buffer).

The diagnostic accuracy and clinical impact of FDG-PET/CT follow-up for patients on adjuvant immunotherapy for high-risk malignant melanoma.

Objective: The benefit of FDG-PET/CT in follow-up of patients treated with adjuvant immunotherapy after resection of high-risk malignant melanoma (MM) is debated. This study evaluated the diagnostic accuracy and clinical impact of FDG-PET/CT for diagnosing MM recurrence during the first year after surgery.

Methods: We retrospectively included 124 patients with resected high-risk MM, who received adjuvant immunotherapy and follow-up FDG-PET/CT.

Colon capsule endoscopy in colorectal cancer screening: Interim analyses of randomized controlled trial CareForColon2015.

 The Danish CareForColon2015 trial, launched in 2020 as part of the Danish Colorectal Cancer Screening program, is the largest randomized controlled trial to date on colon capsule endoscopy (CCE). This paper presents the interim analysis with the objective of ensuring the safety of patients in the intervention group and evaluating the clinical performance of the trial's predefined clinical parameters.  We evaluated the initial 234 CCEs according to quality, safety, and completion.

Assessment of functioning and disability in patients with low back pain - the low back pain assessment tool. Part 2: field-testing.

Purpose: To evaluate comprehensiveness and acceptability of the patient-reported outcome instrument (PRO-LBP) and the clinician-reported outcome instrument (ClinRO-LBP) included in the low back pain (LBP) assessment tool. Second, to assess degree of implementation after three months.

Methods: Feasibility-testing, training of health professionals, field-testing, and a feedback meeting was undertaken.

The effect of an integrated multidisciplinary rehabilitation programme for patients with chronic low back pain: Long-term follow up of a randomised controlled trial.

Objective: To compare the long-term effectiveness of an integrated rehabilitation programme with an existing rehabilitation programme, in terms of back-specific disability, in patients with chronic low back pain.

Design: A single-centre, pragmatic, two-arm parallel, randomised controlled trial.

Setting: A rheumatology rehabilitation centre in Denmark.

Diagnostic Screening for Lumbar Spinal Stenosis.

Purpose: To develop a self-administered diagnostic screening questionnaire for lumbar spinal stenosis (LSS) consisting of items with high content validity and to investigate the diagnostic value of the questionnaire and the items.

Patients And Methods: A self-reported diagnostic LSS screening questionnaire was developed based on items from the existing literature describing key symptoms of LSS. The screening questionnaire (index test) was to be tested in a cohort of patients with persistent lumbar and/or leg pain recruited from a Danish publicly funded outpatient secondary care spine clinic with clinicians performing the reference test.

Back disorder incidence and occupation in Denmark: a cross-sectional register-based study.

Purpose: The purpose of the present paper is (1) to describe the occupational distribution of persons with incident back disorders and (2) to determine the incidence rate ratio (RR) for back pain amongst patients working in specific occupation groups.

Methods: Using Danish registries, a total of 20,921 employed persons with incidents back disorders aged 18-64 years were identified in 2016 based on the inclusion criteria from the Danish Back Register. RR was estimated to test for differences in incident back disorder diagnoses across occupations.
