Declining Coronary Heart Disease Mortality in Iceland: Contribution by Incidence,Recurrence and Case Fatality Rate

Objective : To analyse to what extent the recent decline in coronary heart disease mortality in Iceland is due to changes in incidence, recurrence and case fatality rates. Design : A countrywide registration of myocardial infarction (MI) in people aged 25-74 was performed in Iceland during 1981-1999 according to the MONICA protocol. Possible cases were found by review of all hospital discharge records, autopsy records and death certificates. Results : MI death rate declined by 63% in males and 51% in females, most in the youngest age groups in men (86%) and least in the oldest (49%). In women there was not a significant difference in age groups. Overall the age-adjusted reduction in MI death rate was 55.4% in both sexes combined; of this 23.1% was due to incidence reduction, 22.8% to recurrence reduction and 11.6% to case fatality reduction. In the youngest age groups the decline in incidence contributed most to the decline in MI death rate (62% in men and 71% in women), but thereafter the decline in case fatality in men. In the older age groups decline in recurrence rate has greater weight. Conclusion : The recent decline in MI mortality under the age of 75 years in Iceland is due to reduction in incidence and recurrence rate by about 40% each and to reduction in case fatality by 20%.     

Controlling systolic blood pressure is difficult in patients with diabetic kidney disease exhibiting moderate-to-severe reductions in renal function

This study compared the use of antihypertensive treatment and blood pressure (BP) controls between patients with diabetic kidney disease (DK+) and patients with non-diabetic kidney disease (DK-) exhibiting moderate-to-severe chronic renal failure who did not need renal replacement therapy. A cross-sectional survey included all renal patients with s-creatinine at ?200 micromol/l attending regular control sessions at six renal units in Norway. Of the 351 patients included, 73 (20.8%) were DK+. The proportion reaching a BP goal of <130/80 mmHg was similar in DK+ and DK- (14.1% vs 13.6%, p = 0.92), while 38% and 39% achieved a BP of <140/90 mmHg, respectively. The systolic BP goal was more difficult to achieve than the diastolic BP goal in DK+ patients (35% vs 15%) despite a mean of three different types of drugs being used. Loop diuretics and beta-adrenergic-receptor antagonists were the most frequently prescribed drugs, and the use of angiotensin-converting enzyme inhibitors or angiotensin-II-receptor antagonists declined when renal function deteriorated, from 80% to 0% and from 66% to 20% in the DK+ and DK- groups, respectively (p = 0.001). Thus, despite the use of multiple antihypertensive drugs, controlling BP - especially the systolic BP - is difficult in high-risk patients with chronic renal failure caused by diabetic kidney disease.     

Gastroenteropancreatic neuroendocrine tumors in Iceland: a population-based study

Objective: To determine the incidence, distribution, and prognosis of gastroenteropancreatic neuroendocrine tumors (GEP-NETs) over the last 30 years and analyze changes over time.

Methods: All patients diagnosed with GEP-NETs in Iceland from 1985 to 2014 were identified through the Icelandic Cancer Registry and pathology laboratory records. Relevant clinical information was obtained from medical records. In order to assess trends, the study period was divided into two periods, 1985–1999 and 2000–2014.

Results: A total of 364 patients with GEP-NETs were identified. Overall, 18 patients diagnosed at autopsy or with primary tumors of an unknown site were excluded, leaving 346 patients with 351 primary tumors for final analysis. The overall mean annual incidence 1985–2014 was 3.65/100,000, 3.39/100,000 during 1985–1999 and 3.85/100,000 during 2000–2014 (p?=?NS). The most common primary tumor site was the appendix (32%), followed by the jejunum/ileum (24%) and stomach (17%). In all, 18% of patients presented with distant metastases at the time of diagnosis, most noticeably patients with primary tumors of the colon (47%), pancreas (46%) and jejunum/ileum (39%). The most favorable 5-year survival was observed for tumors of the appendix (94%) and rectum (88%) and the least favorable for tumors of the pancreas (31%), colon (47%) and jejunum/ileum (66%). There were no statistically significant changes in incidence, staging or survival between the two time periods.

Conclusions: In this population-based study, the incidence of GEP-NETs has not changed significantly over the last decades. The incidence of metastatic disease has remained stable and overall prognosis has not improved in recent years.     

Personality, physical activity, and symptoms of anxiety and depression: the HUNT study

Purpose

To analyze the association between physical activity (PA), symptoms of depression and anxiety, and personality traits.

Methods

Cross-sectional study from a Norwegian population-based survey conducted in the period 2006–2008. The sample consisted of a total of 38,743 subjects aged ≥19 years, 56.1 % women and 43.9 % men. Demographic variables, PA, depression and anxiety (The Hospital Anxiety and Depression Scale), and personality (Eysenck Personality Questionnaire) were assessed by self-reporting measurements.

Results

Individuals who reported moderate and high PA had significantly lower scores on depression and anxiety compared with less physically active individuals (p < 0.05). Significantly lower risk of HADS-defined depression and anxiety was associated with frequency, duration, and intensity of activity among women (p < 0.05), and significantly lower risk of HADS-defined depression was associated with frequency, duration, and intensity of activity among men (p < 0.05). There was a significant linear trend between extroversion and levels of PA (p < 0.01) and between neuroticism and PA (p < 0.01).

Conclusions

Subjects reporting regular leisure-time PA were less likely to report symptoms of HADS-defined depression and anxiety. Personality may be an underlying factor in explaining this association.     

Staphylococcus aureus meningitis: experience with cefuroxime treatment during a 16 year period in a Danish region

Staphylococcus aureus is a rare cause of bacterial meningitis and there is no consensus on antibiotic treatment. Nafcillin is a common choice in countries where it is approved and marketed. High-dose cefuroxime has been the systemic treatment used in the study region, and a retrospective record review was conducted to determine its clinical efficacy. Cases of bacterial meningitis during 1984-1999 in the County of North Jutland, Denmark (approx. 490000 inhabitants), were identified in a regional bacteriology register. Inclusion of a case required either growth of S. aureus from > or = 2 specimens of cerebrospinal fluid (CSF), 1 positive CSF specimen with a CSF leucocyte count > 10(8)/l or 1 positive CSF specimen with a concurrent positive blood culture. A diagnosis of brain abscess required growth of S. aureus from aspirated pus. Staphylococcus aureus meningitis was confirmed in 45 patients, and 5 additional patients had a brain abscess. 44 cases were nosocomial (mortality 16%) and 6 were community acquired (mortality 83%). None of the isolates was methicillin resistant and 6 were penicillin susceptible. Intraventricular antibiotic treatment was given to 28 patients, systemic therapy included cefuroxime in 32 patients (64%) as either a primary or secondary choice, 6 (12%) were treated with penicillin G, 10 (20%) with penicillinase-resistant penicillin and 2 (4%) with cephalothin. Among 31 nosocomial cases treated systemically with cefuroxime the mortality was 10% (95% exact confidence limits 2-26%). In conclusion, cefuroxime seems to be a valid choice for S. aureus meningitis in the nosocomial setting.
