Background Fluid retention is a known but underappreciated side-effect of non-steroidal anti-inflammatory drug (NSAID) use. As type 2 diabetes mellitus (T2DM) has been linked to both subclinical cardiomyopathy and a decline in kidney function, short-term NSAID use could lead to subsequently development of heart failure (HF) due to aberrations in fluid balances. Purpose We investigated associations between short-term NSAID use and the risk of HF in a nationwide cohort of patients with T2DM. Methods Using nationwide Danish registers, we identified patients diagnosed with T2DM during 1998–2018. Follow-up began 120 days after first-time T2DM diagnosis among patients without prior heart failure or a rheumatological diagnosis indicating long-term NSAID use. To describe use of NSAID among patients with T2DM, we reported proportions of patients claiming at least 1, 2, 3 or 4 prescriptions of NSAID within one year of start of follow-up. We investigated associations between use of NSAIDs (celecoxib, diclofenac, ibuprofen and naproxen) and new-onset HF hospitalizations using a case-crossover design with 28-day exposure windows and reported odds ratios (OR) with 95% confidence intervals (CI). The case-crossover design uses each individual as his or her own control making it suitable to study the effect of short-term exposure on immediate events while mitigating unmeasured confounding. Sensitivity analyses using exposure windows of 14 and 42 days were performed as well. Results A total of 334,950 patients with T2DM was included (47.7% female, median age of 61 [interquartile range 50–70]). Celecoxib and naproxen were rarely used; on the contrary, prescriptions of diclofenac and ibuprofen were claimed at least once within one year from the beginning of follow-up by 4.9% and 15.5% of patients, respectively–0.9% and 2.7% claimed at least four prescriptions (Figure 1). The risk of new-onset HF hospitalization was increased

Background Treatment with medical cannabis for chronic pain is in popular demand, and a rising number of countries allow physicians to prescribe medical cannabis for pain management. However, data on drug-safety is scarce. Studies have showed a risk of cardiovascular side effects following use of recreational cannabis warranting further investigations into the safety of prescribing medical cannabis. Purpose We investigated risk of new-onset arrhythmias (tachy- or bradyarrhythmia and conduction disorders), acute coronary syndrome (ACS) and heart failure (HF) following use of prescribed medical cannabis compared with no use in a nationwide cohort of patients with chronic pain. Methods Using nationwide Danish registers, a cohort of patients with chronic pain and without prior history of arrhythmias, ACS, HF or prescribed medical cannabis (cannabinoid, cannabidiol or dronabinol) use were followed from 2018–2021. Any patient from the cohort initiating first-time treatment with medical cannabis was identified and matched 1:10 to corresponding controls within the cohort using incidence density sampling. Matching parameters were age group, sex, and chronic pain diagnosis. Follow-up was initiated at the date of the first claimed prescription of medical cannabis or the corresponding date among controls. We reported 180-day standardized absolute risks (AR) with 95% confidence intervals (CI) and risk ratios (RR) from fitted multivariable logistic regression models comparing patients exposed to medical cannabis with patients not exposed. Separate analyses for each chronic pain group were conducted as well. Results Among 1.6 million patients with chronic pain, 4,562 patients claimed at least one prescription of medical cannabis (exposed) and were each matched to 10 controls (non-exposed). Exposed and non-exposed patients were identical in relation to matching parameters; however, exposed patients were slightly more comorbid, and a larger

Background and purpose: Clinical use of continuous electrocardiography (cECG) for detecting atrial fibrillation (AF) after stroke is unclear. In a Danish nationwide cohort, we described post-stroke time trends in outpatient cECG usage and AF incidence and characterized factors associated with cECG use. Methods: Patients without AF discharged after their first ischaemic stroke between 2010 and 2016 were identified from Danish nationwide registries. cECG included Holter or event recording within 120 days from discharge. Cumulative incidence analysis and multivariable adjusted logistic regression were used to assess time trends and factors associated with cECG usage and AF. Results: The study population comprised 39 641 patients. Cumulative use of cECG increased threefold from 3.3% [95% confidence intervals (CI), 2.8–3.8] in 2010 to 10.5% (95% CI, 9.7–11.3) in 2016. Correspondingly, cumulative incidence of post-stroke AF increased from 1.9% (95% CI, 1.5–2.3) to 2.8% (95% CI, 2.4–3.2). Of all cECG-evaluated patients, 6.3% received an AF diagnosis versus 2.2% of the unevaluated. Receiving cECG was associated with increased odds of AF (odds ratio, 3.4; 95% CI, 2.8–4.0). Lower age, milder strokes and less comorbidity were associated with increased odds of receiving cECG. In contrast, risk factors for AF were increasing age and more comorbidity. Conclusions: Post-stroke outpatient cECG use and AF incidence have increased over time, but screening rates were low. cECG use was associated with tripled odds of detecting AF. There was a disparity between factors associated with cECG use and risk factors of AF. This raise questions as to the appropriateness of the current clinical approach to post-stoke AF detection.

Childhood obesity is associated with severe physical and psychological health problems. Interventions are often directed at the whole family, but the literature provides no clear indication of the characteristics of an effective family-based intervention. The objective of the present paper is to study whether and how an analytical framework focusing on communicative authenticity can be used to observe and elaborate upon aspects of adherence in relation to health behavior change in a concrete family-based intervention. We do this by focusing on the families' experiences with a Shared-care health education intervention and thus explore the association between families' self-reported experience and their adherence to the intervention. The dataset consists of 21 in-depth semi-structured family interviews. The study shows that the Shared-care model has potential, but that this potential is rarely fulfilled in the intervention form under study. The sharing of care adds potential for several kinds of communicative authenticity because families are met by both the medical knowledge authority at the hospital and the local nurses in their municipality. It is, however, a significant finding that the families rarely benefit from this potential authenticity. Using theories of authenticity in this context adds theoretical and analytical potential and manages to incorporate elements of participation in tasks and practices of value, a sense of who we are and what we know, negotiation of meaning, emphatic caring, consistency between values and actions, and horizons of significance. The article brings new perspectives on how family-based interventions could be tailored to communicatively suit individual families.

AIM: Necrotising enterocolitis contributes considerably to the mortality of preterm infants, but most questions remain unsolved after decades of extensive research. This Danish study investigated the validity of necrotising enterocolitis diagnoses at discharge according to Bell's staging system.METHODS: We conducted a retrospective single-centre cohort study of 714 preterm infants with a gestational age of less than 30 weeks born in 2006-2013. The infants were diagnosed with necrotising enterocolitis according to Bell's stages 2-3 at discharge and in retrospect by an expert panel, which served as our gold standard.RESULTS: The sensitivity of necrotising enterocolitis diagnosed at discharge was 0.72-0.75 depending on whether spontaneous intestinal perforation was included as necrotising enterocolitis or not. The positive predictive value of the diagnosis was 0.49-0.61. The incidence was significantly higher when diagnosed at discharge than when diagnosed by the expert panel (11.1 versus 9.0%, p = 0.03). The mortality rate for infants who were underdiagnosed at discharge was 50.0%, and it was 25.8% for infants who were overdiagnosed (p = 0.10).CONCLUSION: We found poor validity for the discharge diagnosis of necrotising enterocolitis. In future, a better way of defining the disease is needed for large-scale epidemiologic research.

AIM: This study investigated whether a correlation existed between surgical findings during the first laparotomy for necrotising enterocolitis (NEC) and death and, or, disease progression.METHODS: We included infants admitted within one day of birth to our tertiary neonatal department at Rigshospitalet, Denmark, from 2006 to 2015, who underwent a laparotomy for acute NEC. They were classified according to the locality and extent of intestinal necrosis by a paediatric surgeon, based on the surgical findings. We correlated the surgical findings with postoperative outcomes, namely death and, or, progression of NEC.RESULTS: The first laparotomy showed that 48 infants had NEC, including 21 who demonstrated postoperative progression. Of these, six died before undergoing another laparotomy and 14 of the 15 infants who underwent relaparotomy also died. There was a significant association between surgical findings and NEC-related mortality (p = 0.03). The association between surgical findings and the progression of NEC was also significant (p < 0.0001).CONCLUSION: Surgical findings during laparotomy for NEC were strongly correlated with mortality, which was close to 100% after relaparotomy. Considering the discouraging outcome, further studies should focus on alternative surgical approaches, such as proximal diverting jejunostomy and the clip and drop technique for the treatment of severe NEC.

The association between last 5 days of alcohol intake, semen quality and reproductive hormones was estimated in this cross-sectional study among 347 men. Conventional semen characteristics, DNA fragmentation index and reproductive hormones (testosterone, estradiol, sex hormone-binding globulin (SHBG), follicle-stimulating hormone (FSH), luteinizing hormone (LH) and inhibin B) were determined. There was a tendency towards lower semen characteristics at higher intake of alcohol past 5 days, albeit with no statistically significant dose-response association. The ratio between free estradiol and free testosterone was higher at higher alcohol intake during the 5 days preceding semen sampling. In conclusion, alcohol intake was associated with impairment of most semen characteristics but without a coherent dose-response pattern. The study indicates an association between recent alcohol intake and a hormonal shift towards higher estradiol/testosterone ratio. The hormonal changes observed may over time, lead to adverse effects on semen quality, but longitudinal studies are needed to study this.

Oral anticoagulation (OAC) in patients with atrial fibrillation (AF) is a double-edged sword, because it decreases the risk of stroke at the cost of an increased risk of bleeding. We compared the performance of a new bleeding prediction scheme, HAS-BLED, with an older bleeding prediction scheme, HEMORR(2)HAGES, in a cohort of 'real-world' AF patients.

Concurrent alcohol exposure has been associated with reduced fecundity, but no studies have estimated the effect of prenatal alcohol exposure on male fecundity. The aim of this study was to investigate the association between maternal alcohol consumption during pregnancy, semen quality and levels of reproductive hormones in young, adult men.

Clinical consequences of hospital variation in use of oral anticoagulant therapy after first-time admission for atrial fibrillation. J Intern Med 2009; doi:10.1111/j.1365-2796.2008.02061.xObjective. To analyse how hospital factors influence the use of oral anticoagulants (OAC) in atrial fibrillation (AF) patients and address the clinical consequences of hospital variation in OAC use. Design and subjects. By linkage of nationwide Danish administrative registers we conducted an observational study including all patients with a first-time hospitalization for AF between 1995 and 2004 as well as prescription claims for OAC. Multivariable logistic regression analysis was used to evaluate hospital factors associated with prescription of OAC therapy. Cox proportional-hazard models were used to estimate the risk of re-hospitalization for thromboembolism and haemorrhagic stroke with respect to discharge from a low, intermediate, or high OAC use hospital. Results. Overall 40 133 (37%) out of 108 504 patients received OAC; ranging from 17% to 50% between the hospitals with the lowest and highest OAC use, respectively. Cardiology departments had the highest use of OAC, but neither tertiary university hospitals nor high volume hospitals had higher OAC use than local community hospitals and low volume hospitals. Risk of a thromboembolic event was significantly increased amongst patients from hospitals with a low OAC use (hazard ratio 1.16, confidence interval 1.10-1.22). Notably, higher OAC use was not associated with a higher risk of haemorrhagic stro

Udgivelsesdato: 2009-Feb, Use of some nonsteroidal anti-inflammatory drugs (NSAIDs) is associated with increased cardiovascular risk in several patient groups, but whether this excess risk exists in apparently healthy individuals has not been clarified. Using a historical cohort design, we estimated the risk of death and myocardial infarction associated with the use of NSAIDs. Participants in the study were selected from the Danish population and were defined as healthy according to a history of no hospital admissions and no concomitant selected pharmacotherapy. The source population consisted of 4,614,807 individuals, of whom 1,028,437 were included in the study after applying selection criteria. Compared to no NSAID use, hazard ratios (95% confidence limits) for death/myocardial infarction were 1.01 (0.96-1.07) for ibuprofen, 1.63 (1.52-1.76) for diclofenac, 0.97 (0.83-1.12) for naproxen, 2.13 (1.89-2.41) for rofecoxib, and 2.01 (1.78-2.27) for celecoxib. A dose-dependent increase in cardiovascular risk was seen for selective COX-2 inhibitors and diclofenac. Caution should be exercised in NSAID use in all individuals, and particularly high doses should be avoided if possible.

Large military pay raises and a weak economy have generated record reenlistment levels for the Navy. The consensus appears to be that higher retention is better for the Navy; more experienced Sailors improve readiness and allow the Navy to devote fewer resources to the recruiting, training, and acculturation of new accessions. Given recent increases in reenlistment rates and bonuses, however, further increases may not be cost-effective. This study examines the costs and benefits of retention, and thus develops rating-specific reenlistment goals for the Navy. (U) We estimate that most enlisted personnel are in ratings for which the costs of reenlistment exceed the benefits. In other words, we conclude that the cost-effective level of reenlistment is lower than current goals. The Navy should not, however, make drastic cuts to reenlistment bonuses. Advocating lower-than-recent increases in basic pay, without decimating the SRB budget, is a more cost-effective and flexible approach to lowering reenlistment. (U) Our results also indicate that economic conditions affect the cost-effective reenlistment level. A deterioration of the economy generates higher retention without any increase in bonuses. In contrast, improvements in economic conditions act like a "tax" on SRB effectiveness. Therefore, reenlistment goals will often change with economic conditions.
