Aims: 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). Methods: This was a retrospective cohort study using Danish registries. Results: Our study population included 24,518 patients younger than 61 years and 12,274 patients older than 61 years. In both subpopulations, 60% had a non-specific back pain diagnosis (BPD). In the younger subpopulation, 2.1% of the patients with a non-specific BPD and 1.3% of the patients with a specific BPD had a psychiatric diagnosis within one year of their BPD. In the older subpopulation, 0.6% of patients had a psychiatric diagnosis in both BPD groups. The most frequent psychiatric diagnoses were stress-related disorders. In the younger subpopulation, patients with non-specific back pain had a higher risk of being diagnosed with a psychiatric disorder than patients with specific back pain (adjusted odds ratio 1.56, 95% confidence interval 1.25–1.94). The type of BPD had no effect on the risk of having a psychiatric diagnosis among older patients. Conclusions: Patients with a non-specific back pain disorder younger than 61 years were more likely to be diagnosed with a psychiatric disorder than patients with a specific back pain disorder. We recommend that spine specialists pay special attention to patients younger than 61 years with a back pain disorder to prevent them from developing a psychiatric disorder. [ABSTRACT FROM AUTHOR]

Purpose Primary lung cancer is one of the most common types of cancers. Comorbidity has been shown to be a negative prognostic factor in the overall lung cancer population. The significance of the individual comorbidities is less well known. The purpose of this paper is to investigate the effect of each comorbid disease groups on survival. Methods The analysis is based on all patients with NSCLC who were registered in 2009-2011, in total 10,378 patients. To estimate the effect of each comorbidity group on the survival, we fitted a Cox regression model for each comorbidity group adjusting for age, sex, resection, and stage. Results Patients with cardiovascular comorbidity have a 30 % higher death rate [HR 1.30 with 95 % CI (1.13; 1.49)] than patients without comorbidity. Patients with diabetes and patients with cerebrovascular disorders and COPD have a 20 % excess mortality than patients without comorbidity: [HR 1.19 with CI (1.02; 1.39) for diabetes, HR 1.18 with CI (1.05; 1.33) for cerebrovascular disorders, and HR 1.20 with CI (1.10; 1.39 for COPD)]. Conclusion Our study shows the importance of cardiovascular disease in lung cancer. Diabetes, cerebrovascular disorders, and COPD also have a significant impact on survival of NSCLC patients., Author(s): Maria Iachina[sup.1] [sup.2] , Erik Jakobsen[sup.3] [sup.4] , Henrik Møller[sup.5] , Margreet Lüchtenborg[sup.5] , Anders Mellemgaard[sup.6] , Mark Krasnik[sup.7] , Anders Green[sup.4] Author Affiliations: (1) Center for Clinical Epidemiology, [...]

Background. Androgenetic alopecia is the most common type of hair loss in men, but little is known about the etiology of androgenetic alopecia in elderly men and its impact on perceived age. Here we used a population-based twin study of men aged 70+ to assess the magnitude of the genetic component affecting hair loss and to examine the association between baldness and perceived age. Methods. In the fourth wave of The Longitudinal Study of Aging Danish Twins we obtained digital photos of the face and photos of the vertex area of 739 elderly male twins, including 148 intact twin pairs. The degree of baldness and perceived age were assessed in each twin by five and nine nurses, respectively. The heritability of balding was estimated using structural-equation analysis, and it was tested whether baldness was associated with estimations of age. Results. The intrapair correlation of degree of balding was consistently higher for monozygotic than for dizygotic twin pairs regardless of the baldness categorization used, and structural-equation analysis revealed a heritability of 79% (95% confidence interval, 0.40-0.85) for the mean baldness index. The remaining variation could be attributed to nonshared environmental effects. There was only a very weak and statistically nonsignificant association between baldness and overestimation of age. Conclusions. The majority of the variation in baldness in elderly men can be explained by genetic factors, and hair quantity has little impact on perceived age in elderly men.

Abstract Background CT screening for lung cancer has recently been shown to reduce lung cancer mortality, but screening may have adverse mental health effects. We calculated risk ratios for prescription of anti-depressive (AD) or anxiolytic (AX) medication redeemed at Danish pharmacies for participants in The Danish Lung Cancer Screening Trial (DLCST). Methods The DLCST was a randomized clinical trial which comprised 4,104 former or present smokers who were randomized from 12 May 2004 to 20 June 2006 to either CT scan of the chest, lung-function test and filling in questionnaires annually for five years in the period 1 April 2006–31 March 2010 (n = 2,052), or to a control group (n = 2,052) receiving similar procedures except CT scan. We used CT scan intervention group versus control group status as exposure. The follow-up period for use of AD or AX was three years. Baseline data on civil status, socioeconomic status, and co-morbidity as well as outcome data on AD and AX were obtained by linkage to national registries. Results The intervention and the control groups did not differ by age, gender, civil status, socio-economic position, co-morbidity index or former use of AD or AX. The adjusted risk ratio for at least one recipe of AD or AX in the CT intervention group during follow-up was not increased when adjusting for previous use of AD or AX, HR 1.00, 95 % CI (0.90-1.12). Similar results were seen when excluding subjects using AD or AX in a four-month or two-year period before baseline, when analyzing AD and AX separately, or requiring at least two recipes. Conclusions We found no indications that participation in a lung cancer CT-screening program increases the risk of specific adverse mental health outcomes.

OBJECTIVES: The study has been performed to investigate the mortality within the first year after resection in patients with primary lung cancer, together with associated prognostic factors including gender, age, tumour stage, comorbidity, alcohol abuse, type of surgery and post-surgical complications. METHODS: All patients (n = 3363) from the nationwide Danish Lung Cancer Registry with first resection performed between 1 January 2007 and 31 December 2011 were analysed by Kaplan–Meier techniques and Cox-regression analysis concerning death within the first year after resection. Covariates included gender, age, comorbidity (Charlson comorbidity index), perioperative stage, type of resection, registered complications to surgery and alcohol abuse. RESULTS: The cumulative deaths after 30 days, 90 days, 180 days and 360 days were 72 (2.1%), 154 (4.6%), 239 (7.1%) and 478 (14.2%), respectively. Low stage, female gender, young age, no comorbidity, no postoperative complications, no alcohol abuse and lobectomy as type of resection were favourable for survival. CONCLUSIONS: Our results demonstrate that resection in primary lung cancer impacts mortality far beyond the initial 30 days after resection, which is conventionally considered a time window of relevance for the adverse outcome of surgery. Increased efforts should be made for optimizing the selection of patients suited for resection and for identifying patients at increased risk of death after resection. Furthermore, patients should be monitored more closely and more frequently, in particular those patients with high risk of death after resection. [ABSTRACT FROM AUTHOR]
