PURPOSE: To explore smoking cessation between cancer survivors and cancer-free women, and the potential survival benefits from smoking cessation in cancer surviving women.

METHOD: We pooled 46,334 responses from the Danish Nurse Cohort. The cohort consists of female nurses, who were invited for surveys in 1993, 1999 and 2009. Participants were linked to nationwide registries on hospitalization, cause of death and migration through 2016. Odds for smoking cessation by cancer diagnosis were computed in propensity score matched logistic regression models, while survival by postdiagnosis smoking cessation was estimated in cox proportional hazards models.

RESULTS: Eligible for analysis were 7841 women (mean age = 56.7 years, SD ± 7.2), who were smokers at baseline and survived to the next follow-up survey. Of these, 545 women were diagnosed with cancer and matched by propensity score (1:2) with 1090 cancer-free women. Odds for smoking cessation were significantly higher in cancer-diagnosed women compared to their cancer-free peers (OR = 1.31, 95% CI: 1.06-1.61). Moreover, mortality risk was significantly lower among cancer survivors who stopped smoking (HR = 0.64, 95% CI: 0.46-0.91), compared to persistent smokers.

CONCLUSIONS: The results suggest considerable survival benefits from smoking cessation in cancer surviving female nurses, and that the time surrounding cancer diagnosis may serve as a teachable moment for smoking cessation. However, due to substantial methodological limitations embedded in the study, careful interpretation of the presented results is warranted. Future studies are needed to demonstrate the effects of diagnosis on smoking cessation as well as the effects of smoking cessation on survival in female cancer populations.

Team handball is a fast high-scoring indoor contact sport with > 20 million registered players who are organized in > 150 federations worldwide. The combination of complex and unique biomechanics of handball throwing, permitted body tackles and blocks, and illegal fouls contribute to team handball ranging among the four athletic sports that carry the highest risks of injury. The categories include a broad range of acute and overuse injuries that most commonly occur in the shoulder, knee, and ankle. In concert with sports medicine, physicians, surgeons, physical therapists, and radiologists consult in the care of handball players through the appropriate use and expert interpretations of radiography, ultrasonography, CT, and MRI studies to facilitate diagnosis, characterization, and healing of a broad spectrum of acute, complex, concomitant, chronic, and overuse injuries. This article is based on published data and the author team's cumulative experience in playing and caring for handball players in Denmark, Sweden, Norway, Germany, Switzerland, and Spain. The article reviews and illustrates the spectrum of common handball injuries and highlights the contributions of sports imaging for diagnosis and management.

The typical Hidradenitis Suppurativa (HS) patient is a young woman with axillary and groin involvement, but the spectrum of the disease presentation is broad and no internationally acknowledged sub-classification of the disease exists to date. It is however speculated that different, yet unidentified, subtypes may respond differently to different treatments or carry a different prognosis. Classification according to self-reported clinically meaningful outcomes for patients offer practical advantages. Our objective was to build an empirical framework for sub-classification of HS patients based on the frequency of HS flares in various anatomic locations, using a cross-sectional questionnaire-based design. All patients with a clinically confirmed diagnosis of HS registered at our department until March 1, 2017 were invited to participate. The frequency of HS flares in various anatomic locations was used for identification of possible HS subtypes using Principal Component Analysis (PCA) and cluster analysis. A total of 524 (62%) of 845 invited patients answered the questionnaire; 402 (76.7%) were female. From the cluster analysis, we identified two possible subtypes of HS, labeled the "upper type" and the "lower type". The "upper type" was characterized by repeated outbreaks in axillary and mammary regions. Meanwhile, the "lower type" was characterized by outbreaks in the inguinal, genital, perianal, and gluteal regions. Our findings support the notion that HS can be sub-classified and imply that the pattern of where lesions are located may be an important element in future HS sub-classification systems.

OBJECTIVE: To evaluate the 18-month post-intervention efficacy following a four-month individually tailored, behavioral intervention on daily sitting time in patients with rheumatoid arthritis (RA). The four-month post-intervention results showed that patients in the intervention reduced their daily sitting time, improved patient-reported outcomes and total cholesterol levels compared to the control group.

METHODS: In an observer-blinded randomized trial, 150 RA patients were included. During four months, the intervention group (n=75) received three motivational counselling sessions and tailored text messages aimed at increasing light-intensity physical activity through reduction of sedentary behavior. The control group (n=75) maintained usual lifestyle. Primary outcome was change from baseline to 18 months post intervention in objectively measured daily sitting time (ActivPAL). Secondary outcomes included changes in clinical patient-reported outcomes and cardio-metabolic biomarkers. A mixed effect repeated measures ANCOVA model in the intention-to-treat population was applied.

RESULTS: At 22-months follow-up from baseline, 12 participants were lost to follow-up. Compared to baseline, sitting time in the intervention group decreased 1.10 h/day, whereas it increased by 1.32 h/day in the control group; between-group difference of -2.43 h/day (95%CI: -2.99;-1.86; p<0.0001) favoring the intervention group. For most secondary outcomes between-group differences favored the intervention: VAS-pain: -15.51 mm (-23.42;-7.60), VAS-fatigue: -12.30 mm (-20.71;-3.88), physical function: -0.39 HAQ-units (-0.53;-0.26), total cholesterol: -0.86 (-1.03;-0.68), triglyceride: -0.26 (-0.43;-0.09) and average glucose: -1.15 (-1.39;-0.91) mmol/l.

CONCLUSION: Eighteen months after intervention, patients in the intervention group were still significantly less sedentary than controls. Findings suggest that a behavioral approach is beneficial for promoting long-term physical activity and health in patients with RA.

PURPOSE: The Copenhagen Primary Care Laboratory Pregnancy (CopPreg) database was established based on data from The Danish Medical Birth Register and the Copenhagen Primary Care Laboratory (CopLab) database. The aim was to provide a biomedical and epidemiological data resource for research in early disease programming (eg, parental clinical biomarker levels and pregnancy/ birth outcomes or long-term health in the offspring).

PARTICIPANTS: The cohort consisted in total of 203 608 women (with 340 891 pregnancies) who gave birth to 348 248 children and with 200 590 related fathers. In this paper, we focused on women and fathers who had clinical test requisitions prior to and during pregnancy, and on all children. Thus, the cohort in focus consisted of 203 054 pregnancies with requisitions on 147 045 pregnant women, 39 815 fathers with requisitions during periconception and 65 315 children with requisitions.

FINDINGS TO DATE: In addition to information on pregnancy and birth health status and general socio-demographic data, over 2.2 million clinically relevant test results were available for pregnancies with requisitions, over 1.5 million for children and over 600 000 test results were available for the fathers with requisitions during periconception. These were ordered by general practitioners in the primary care setting only and included general blood tests, nutritional biomarkers (macronutrients and micronutrients) and hormone tests. Information on tests related to infections, allergies, heart and lung function and sperm analyses (fathers) were also available.

FUTURE PLANS: The CopPreg database provides ready to use and valid data from already collected, objectively measured and analysed clinical tests. With several research projects planned, we further invite national and international researchers to use this vast data resource. In a coming paper, we will explore and discuss the indication bias in our cohort.

OBJECTIVE: To evaluate the structural effects of weight loss on hip or knee osteoarthritis (OA) and to summarize which structural joint pathologies have been examined and the evidence for the outcome measurement instruments applied.

DESIGN: Based on a pre-specified protocol (available: PROSPERO CRD42017065263), we conducted a systematic search of the bibliographic databases, Medline, Embase and Web of Science identifying longitudinal articles reporting the effects of weight loss on structural imaging outcomes in OA of the hip or knee in people who are overweight or obese.

RESULTS: From 1625 potentially eligible records, 14 articles (from 6 cohorts) were included. 2 cohorts were derived from RCTs. Evaluated pathologies were: articular cartilage (n = 7), joint space width (n = 3), bone marrow lesions (n = 5), synovitis (n = 2), effusion (n = 1), meniscus (n = 3), bone marrow density (n = 1) and infrapatellar fat pad (IPFP; n = 2). Cartilage showed conflicting results when evaluating cartilage thickness by direct thickness measurements. Compositional dGEMRIC and T2 mapping measures in early knee OA showed trends towards reduced cartilage degeneration. Joint space width on conventional radiographs showed no change. Weight loss reduced the size of the IPFP. Synovitis and effusion were not affected. Following weight loss DXA showed bone loss at the hip.

CONCLUSION: We did not find consistent evidence of the effects of weight loss on OA structural pathology in people who are overweight or obese. There is a need to achieve consensus on which structural pathologies and measurements to apply in weight loss and OA research.

OBJECTIVE: To study the impact of weight loss on inflammation in individuals with overweight and knee osteoarthritis (OA) using both static- and dynamic contrast-enhanced (DCE)-MRI and assess the association of these changes to pain.

DESIGN: Individuals with overweight (BMI > 27) and knee OA were examined before and after a >5% weight loss over 8 weeks (ClinicalTrials.gov NCT02905864). Using 3-T MRI, inflammation was quantified from non-contrast enhanced static-MRI according to MOAKS and contrast enhanced static MRI according to BLOKS and 11-point whole-knee synovitis score. DCE-MRI was used to assess the inflammation in the infra patellar fat pad (IPFP). Pain was assessed using KOOS.

RESULTS: Complete data were available in 117 participants with a mean age of 60 years, BMI of 35 kg/m2 and KOOS pain score of 64. Mean weight loss was 12 kg and KOOS pain was improved by 13 points at follow-up. Change in inflammation was not associated with weight loss in static MRI. None of the MRI variables correlated with the change in KOOS pain.

CONCLUSION: Weight loss did not induce a significant change in inflammation in individuals with overweight and OA. The significant clinical beneficial effect of weight loss on knee pain in individuals with overweight and knee OA seems uncoupled to changes in imaging markers of synovitis.
