Self-harm and violent criminality linked with parental death during childhood.

BACKGROUND: Adverse health and social outcomes are known to occur more frequently following parental death during childhood, but evidence is lacking for comparing long-term risks of internalised v. externalised harm. METHODS: This national register-based cohort study consisted of Danish persons born 1970-2000. The Civil Registration System and National Causes of Death Register were linked to ascertain parental deaths by cause before cohort members' 15th birthdays. From age 15 years, hospital-treated self-harm episodes were ascertained through linkage to the National Patient Register and the Psychiatric Central Research Register, and violent crimes were identified via linkage to the National Crime Register. Hazard ratio and cumulative incidence values were estimated. RESULTS: Self-harm and violent criminality risks were elevated following parental death during childhood. Covariate adjustment for gender, birth year and first-degree relatives' mental illnesses attenuated these associations, although significantly heightened risks persisted. The estimated hazard ratios did not differ greatly according to which parent died, but losing both parents conferred particularly large risk increases. Risks for both adverse outcomes were higher in relation to unnatural v. natural parental death; violent criminality risk was especially raised among individuals exposed to parental death by unnatural causes other than suicide. The association was strongest when pre-school age children experienced parental death. CONCLUSIONS: Effective early intervention is needed to help youngsters who have experienced the death of one or both parents to develop immediate and sustained coping strategies. Enhanced cooperation between health and social services and criminal justice agencies may mitigate risks for these two destructive behaviours.

Prenatal exposure to systemic antibacterials and overweight and obesity in Danish schoolchildren: a prevalence study.

BACKGROUND/OBJECTIVE: Prenatal exposure to antibacterials may permanently dysregulate fetal metabolic patterns via epigenetic pathways or by altering maternal microbiota. We examined the association of prenatal exposure to systemic antibacterials with overweight and obesity in schoolchildren. SUBJECTS/METHODS: We conducted a prevalence study among Danish schoolchildren aged 7-16 years using data from routine school anthropometric evaluations conducted during 2002-2013. Prenatal exposure to antibacterials was ascertained by using maternal prescription dispensations and infection-related hospital admissions during pregnancy. We defined overweight and obesity among the children using standard age- and sex-specific cutoffs. We computed sex-specific adjusted prevalence ratios (aPRs) of overweight and obesity associated with exposure to prenatal antibacterials, adjusting for maternal age at delivery, marital status, smoking in pregnancy and multiple gestation; we also stratified the analyses by birth weight. RESULTS: Among 9886 schoolchildren, 3280 (33%) had prenatal exposure to antibacterials. aPRs associated with the exposure were 1.26 (95% confidence interval (CI): 1.10-1.45) for overweight and 1.29 (95% CI: 1.03-1.62) for obesity. Among girls, aPRs were 1.16 (95% CI: 0.95-1.42) for overweight and 1.27 (95% CI: 0.89 to 1.82) for obesity. Among boys, aPRs were 1.37 (95% CI: 1.13-1.66) for overweight and 1.29 (95% CI: 0.96-1.73) for obesity. The aPR for overweight was higher among schoolchildren with birth weight <3500 g (aPR: 1.30, 95% CI: 1.05-1.61) than in schoolchildren with birth weight ⩾3500 g (aPR: 1.18, 95% CI: 0.95-1.46). Inversely, the association for obesity was higher among schoolchildren with birth weight ⩾3500 g (aPR: 1.35, 95% CI: 1.00-1.81) than among those who were <3500 g at birth (aPR: 1.16, 95% CI: 0.82-1.65). CONCLUSIONS: Prenatal exposure to systemic antibacterials is associated with an increased risk of overweight and obesity at school age, and this association varies by birth weight.

Absolute risks of self-harm and interpersonal violence by diagnostic category following first discharge from inpatient psychiatric care.

BACKGROUND: Persons discharged from inpatient psychiatric services are at greatly elevated risk of harming themselves or inflicting violence on others, but no studies have reported gender-specific absolute risks for these two outcomes across the spectrum of psychiatric diagnoses. We aimed to estimate absolute risks for self-harm and interpersonal violence post-discharge according to gender and diagnostic category. METHODS: Danish national registry data were utilized to investigate 62,922 discharged inpatients, born 1967-2000. An age and gender matched cohort study was conducted to examine risks for self-harm and interpersonal violence at 1 year and at 10 years post-discharge. Absolute risks were estimated as cumulative incidence percentage values. RESULTS: Patients diagnosed with substance misuse disorders were at especially elevated risk, with the absolute risks for either self-harm or interpersonal violence being 15.6% (95% CI 14.9, 16.3%) of males and 16.8% (15.6, 18.1%) of females at 1 year post-discharge, rising to 45.7% (44.5, 46.8%) and 39.0% (37.1, 40.8%), respectively, within 10 years. Diagnoses of personality disorders and early onset behavioral and emotional disorders were also associated with particularly high absolute risks, whilst risks linked with schizophrenia and related disorders, mood disorders, and anxiety/somatoform disorders, were considerably lower. CONCLUSIONS: Patients diagnosed with substance misuse disorders, personality disorders and early onset behavioral and emotional disorders are at especially high risk for internally and externally directed violence. It is crucial, however, that these already marginalized individuals are not further stigmatized. Enhanced care at discharge and during the challenging transition back to life in the community is needed.

Therapeutic delay reduces survival of rectal cancer but not of colonic cancer.

BACKGROUND: The relationship between therapeutic delay and long-term survival from colorectal cancer is unclear. This association was examined prospectively among patients with colorectal cancer in Denmark. METHODS: A total of 740 patients with colorectal cancer were included in a prospective, population-based study in three Danish counties from 1 January 2001 to 31 July 2002. Delay was determined by self-report during a standardized interview. Cox proportional hazards regression was used to compute the hazard ratio (HR) associated with delay, while adjusting for age, sex and co-morbidity, and also for urgency of surgery in patients with colonic cancer. RESULTS: For rectal cancer only, a time span of at least 60 days from the onset of symptoms until treatment (total therapeutic delay) was associated with a 69 per cent higher risk of mortality compared with a total therapeutic delay of less than 60 days (HR 1.69 (95 per cent confidence interval 1.01 to 2.83)). Provider delay (interval from first physician contact until treatment) and hospital delay (interval from referral to a hospital until treatment) of at least 60 days had no impact on survival from colorectal cancer. CONCLUSION: A total therapeutic delay of at least 60 days was a negative prognostic factor for long-term survival from rectal cancer.

Granulocyte enzymes and complement after an anaphylactoid reaction to coronary angiography.

An anaphylactoid reaction following angiography with ioxaglate in a 59-year-old man implied generalized pruritus, angioedema, bronchospasm and hypotension. Leucocytosis and an increased number of neutrophils were observed from 90 min to 8 h after the reaction. Elevated values of the neutrophil specific enzymes elastase and lactoferrin were demonstrated. The concentrations of C3d and CH50 did not change which indicate that no complement activation took place.

Influence of radiographic contrast media on granulocyte enzymes and complement during uncomplicated urographies.

Four different radiographic contrast media (RCM) were used for i.v. urography in 40 patients, none of whom had complications. No rise in C3d was observed for any of the RCM, indicating that complement was not activated. However, significantly decreased values for CH50 were detected when the non-ionic RCM iopamidol and iohexol were used, and this may be due to interaction between the RCM and the complement molecules. Significantly increased numbers of neutrophils were observed in patients receiving ioxaglate, iohexol and diatrizoate, which may be due to inhibition of granulocyte adherence. No rise in the concentration of elastase and lactoferrin was observed. On the other hand, significantly decreased values of elastase were seen after injection of diatrizoate, which may be due to inhibition of the degranulation process by this media.

Leukocytes in peritoneal dialysis effluents. Danish Study Group on Peritonitis in Dialysis (DASPID).

The concentration of leukocytes and the fraction of neutrophil granulocytes are two important criteria in the diagnosis of peritonitis in continuous ambulatory peritoneal dialysis (CAPD). We have found that leukocytes are unstable in dialysis effluents, resulting in false low leukocyte concentrations if not counted immediately. At 25 degrees C the leukocyte count decreases 25%-30% in 4-6 hours. Sampling in tubes containing EDTA and storage at 4 degrees C make the leukocyte concentration stable for 6 hours, while the combination of EDTA and storage at 4 degrees C ensures stability for 24 hours. When samples are handled accordingly, concentrations as high as 2 x 10(8)/L are observed without any clinical signs of peritonitis, especially within the first months of CAPD-treatment. Thus, we suggest a leukocyte-concentration of 2 x 10(8)/L as the diagnostic limit for peritonitis. Concerning fraction of neutrophils a diagnostic limit of 0.50 still seems relevant.

[Macro creatine kinase. A cause of diagnostic problems in acute myocardial infarction]. / Makro-kreatinkinase. En årsag til diagnostiske problemer ved akut myokardieinfarkt.

Macro-creatine-kinase type 1 consists of complexes of CKBB isoenzyme and an immunoglobulin, most frequently IgG, while type 2 is probably aggregates of mitochondrial CK. The prevalences of type 1 and 2 have been found to be 0.9%-1.6% and 0.5%-2.9%, respectively, depending on the patient population investigated and the methods of analyses used. Problably a maximum of 1% of patients with suspected AMI, has macro-CK in concentrations causing diagnostic difficulties. In such patients, increased absolute and relative activities of CKB residual as measured by the immuno-inhibition method are found. In specific immunological methods for measuring CKMB concentrations in serum, macro-CK is not measured. However, it has been published, that these methods may underestimate the CKMB concentration in patients with free antibodies to CKB in the blood. In this department, we have evaluated a new analysis for measuring CKMB, without finding any evidence of such interference.

[Natural history of abdominal aortic aneurysm with and without concomitant chronic obstructive pulmonary disease]. / Abdominale aortaaneurismers naturhistorie med og uden coeksisterende kronisk obstruktiv lungelidelse.

The relationship between abdominal aortic aneurysms (AAA) and chronical obstructive pulmonary disease (COPD), and in particular the suggested common elastin degradation caused by elastase and smoking was analysed by a cross sectional population mass screening study for AAA, and a prospective cohort study of small AAA. All previous computer-hospital-recorded diagnoses were received concerning 4,404 men invited to screening for AAA. One hundred and forty-one had AAA (4.2%). They were asked for an interview, a clinical examination, and a blood sample. Men with an AAA of 3-5 cm were offered annual control-scans to check for expansion. Of COPD-patients, 7.7% had AAA (crude OR = 2.05), however the adjusted OR was only 1.53 after adjusting for other co-existing diseases (p = 0.13). The mean annual expansion was 2.74 mm per year in COPD patients and 2.72 in non-COPD patients, and 4.7 mm in oral steroid-users compared to 2.6 in non-steroid-users (p < 0.05). S-elastin-peptides (SEP) and P-elastase-alpha1-antitrypsin-complexes (PEAC) were negatively correlated to FEV1 in COPD-patients. However, SEP, beta-agonist-treatment, and FEV1 was positively correlated to expansion by multivariate regression analysis, while PEAC and S-alpha1-antitrypsin did not influence expansion, suggesting elastase plays a major role in the pathogenesis of COPD but not in AAA. The high prevalence of AAA among patients with COPD is more likely to be caused by medication and coexisting diseases rather than a common pathway of pathogenesis.

[Peritonitis with continuous ambulatory peritoneal dialysis. Status and future perspectives]. / Peritonitis ved kontinuerlig ambulant peritoneal dialyse. Status og fremtidsperspektiver.

Peritonitis remains the major complication of continuous ambulatory peritoneal dialysis. A review is given of the clinical, microbiological, immunological, and pathogenic aspects of this problem and new fields of research for reducing the incidence of peritonitis are suggested.

[Anticoagulant treatment]. / Antikoagulationsbehandling.

In 1998, the sale of vitamin K antagonists (VKA) in Denmark corresponded to the amount used for treatment of more than 20,000 patients for one year. This is more than three times more than ten years earlier. The reasons for the increasing use of VKA are new indications for permanent anticoagulant treatment, especially chronic atrial fibrillation and venous thromboembolism associated with permanent thromboembolic risk factors. The risk of bleeding is higher in the introductory phase of anticoagulant treatment than later on. It is now recommended to commence anticoagulant therapy without a loading dose. This seems to hasten a good estimate of the maintenance dose. The metabolism of VKA depends on a number of genetic and acquired factors. Knowledge of these factors is crucial for optimal regulation of the treatment, and it is important that patients at start of treatment are thoroughly informed about these factors in order to minimize the risk of complications.

[A randomized controlled trial of the use of CRP rapid test as a guide to treatment of respiratory infections in general practice]. / Randomiseret, kontrolleret undersøgelse af anvendelsen af CRP-hurtigtest som vejledning ved behandlingen af luftvejsinfektioner i almen praksis.

INTRODUCTION: The aim was to assess whether the frequency of antibiotic prescriptions to patients with respiratory infections is reduced when general practitioners (GPs) use a CRP rapid test to support their clinical assessment, and to examine whether the use of the test would have any effect on the course of disease. MATERIAL AND METHOD: A randomised controlled trial was carried out by 35 general practices in the County of Funen, Denmark, with 812 patients with respiratory infection. The main outcome measures were frequency of antibiotic prescriptions and morbidity one week after the consultation, as stated by the patients. RESULTS: The frequency of antibiotic prescriptions was 43% (179/414) in the CRP group and 46% (184/398) in the control group (NS, OR = 0.9). At one week, increased or unchanged morbidity was stated more frequently in the CRP group (12%) than in the control group (8%) (OR = 1.6, p = 0.05). In the control group, the variable having the greatest influence on whether the GP prescribed antibiotics was the patient's general well-being (OR = 2.9, p < 0.0001), whereas in the CRP group the CRP value had the greatest influence (OR = 1.1 per unit increase [mg/l], p < 0.0001). CONCLUSION: From on the present study, the use of a single CRP rapid test to support possible antibiotic treatment of respiratory infections in general practice cannot be recommended.

Mortality and incidence of new primary cancers in men with prostate cancer: a Danish population-based cohort study.

BACKGROUND: Prostate cancer (PC) survivors may have an increased risk of new primary cancers (NPCs) due to shared risk factors or PC-directed treatments. METHODS: Using Danish registries, we conducted a cohort study of men with (n=30,220) and without PC (n=151,100) (comparators), matched 1:5 on age and PC diagnosis/index date. We computed incidence rates of NPCs per 10,000 person years (PY) and associated 95% confidence intervals (CI), and used Cox proportional hazards regression to compute hazard ratios (HRs) and 95%CI, adjusting for comorbidities. In order to obviate any impact of shorter survival among prostate cancer patients, we censored comparator patients when the matched prostate cancer patient died or was censored. RESULTS: Follow-up spanned 113,487PY and 462,982PY in the PC and comparison cohorts, respectively. 65% of the cohorts were aged >70 years at diagnosis. Among PC patients, 51% had distant/unspecified stage, and 63% had surgery as primary treatment. The PC cohort had lower incidence of NPCs than their comparators. The adjusted HR of NPC among men with PC versus the comparators was 0.84 (95%CI=0.80, 0.88). Lowest HRs were among older men, those with distant stage, and were particularly evident for cancers of the brain, liver, pancreas, respiratory, upper gastrointestinal, and urinary systems. CONCLUSIONS: We find no evidence of an increased risk of NPCs among men with PC. The deficit of NPCs among men with PC may be a true effect but is more likely due to lower levels of risk factors (e.g., smoking) in PC patients versus comparators, clinical consideration of cancers at new organs as metastases rather than new primaries, or under-recording/under-reporting of NPCs among PC patients.
