Abstract
OBJECTIVES: HIV/AIDS surveillance methods are under revision as the diversity of HIV epidemics is becoming more apparent. The so called "2nd generation surveillance (SGS) systems" aim to enhance surveillance by broadening the range of indicators to prevalence, behaviors and correlates, for a better understanding and a more complete and timely awareness of evolving epidemics. METHODS: Concepts of HIV SGS are reviewed with a special focus on injecting drug users, a major at-risk and hard to reach group in Europe, a region with mainly low or concentrated epidemics. RESULTS: The scope of HIV/AIDS surveillance needs to be broadened following principles of SGS. Specifically for IDUs we propose including hepatitis C data as indicator for injecting risk in routine systems like those monitoring sexually transmitted infections and information on knowledge and attitudes as potential major determinants of risk behavior. CONCLUSIONS: The suggested approach should lead to more complete and timely information for public health interventions, however there is a clear need for comparative validation studies to assess the validity, reliability and cost-effectiveness of traditional and enhanced HIV/AIDS surveillance systems.

Abstract
OBJECTIVE: Few community studies have addressed the longitudinal course of post-traumatic stress disorder (PTSD) in traumatized refugees in early resettlement. This longitudinal study investigated changes from the first (T1) to the second interview (T2), 3 years later. The relationship between traumatic exposures and psychosocial factors/psychological symptom load were examined. METHOD: Local health professionals performed the interviews, using rating scales and a structured questionnaire. A total of 240 (52%) refugees attended. RESULTS: Unchanged Hopkins Symptom Checklist-25 and increase in Harvard Trauma Questionnaire and post-traumatic stress symptoms-16 between T1 and T2 were found, indicating the severity and chronicity of problems. Mean post-traumatic stress score was 15% above cut-off. Severe life-threatening trauma and present life in exile with unemployment and unresolved family reunion were risk factors. CONCLUSION: Early diagnostic interview should be followed by targeted approach. Pinpointing those in need of specialist services is essential. An interdisciplinary approach is necessary in this work.

Abstract
Drug dependency may develop during long-term benzodiazepine use, indicated, for example, by dose escalation. The first benzodiazepine chosen may affect the risk of dose escalation.
To detect possible differences in benzodiazepine use between new users of diazepam and oxazepam over time.
This 5-year prescription database study included 19 747 new benzodiazepine users, inhabitants of Norway, aged 30-60 years, with first redemption for diazepam or oxazepam.
Individuals starting on diazepam versus oxazepam were analysed by logistic regression with sex, age, other drug redemptions, prescriber's specialty, household income, education level, type of work, and vocational rehabilitation support as background variables. Time to reach a daily average intake of =1 defined daily doses (DDD) over a 3-month period was analysed using a Cox proportional hazard regression model.
New users of oxazepam had a higher risk for dose escalation compared with new users of diazepam. This was true even when accounting for differences in sociodemographic status and previous drug use (hazard ratio [HR] 1.33, 95% confidence interval = 1.17 to 1.51).
Most doctors prescribed, according to recommendations, oxazepam to individuals they may have regarded as prone to and at risk of dependency. However, these individuals were at higher risk for dose escalation even when accounting for differences in sociodemographic status and previous drug use. Differences between the two user groups could be explained by different preferences for starting drug, DDD for oxazepam being possibly too low, and some unaccounted differences in illness.

Abstract
BACKGROUND: We hypothesize that premenopausal endogenous estradiol may be associated with age at menarche and adult overweight and obesity, potentially contributing to breast cancer risk. METHODS: We assessed age at menarche by questionnaire among 204 healthy Norwegian women, aged 25-35 years. Measures of body composition included body mass index (BMI, kg/m(2)), waist circumference (WC, cm), waist-to-hip ratio (WHR) and fat percentage dual energy X-ray absorptiometry, (DEXA). Daily salivary 17-beta-estradiol (E(2)) concentrations were collected throughout one entire menstrual cycle and assessed by radioimmunoassay (RIA). Linear regression analyses and linear mixed models for repeated measures were used and potential confounding factors and effect modifiers were tested. RESULTS: Among women with an early age at menarche (

Abstract
OBJECTIVE: This study was designed to evaluate the long-term effect of a campaign to avoid prone sleeping on the sudden infant death syndrome (SIDS) mortality rate and on parents' choice of sleeping position for young infants. Before the campaign, 64% of infants usually slept prone and the SIDS rate was 3.5 (95% CI, 2.64 to 4.36) per 1000 live births. STUDY DESIGN: Population-based case reference study of infants dying suddenly and unexpectedly at the ages of 1 week to 1 year, and of 493 healthy infants between 2 and 6 months of age, starting 4 years after an intervention program to avoid prone sleeping. RESULTS: The SIDS rate was 0.3 per 1000 live births (95% CI, 0.05 to 0.54). One of five (20%) SIDS victims usually slept prone, three of five (60%) were placed prone for their last sleep, and five of six were found dead in the prone position. Of the reference infants, 1.4% were usually placed prone to sleep, although all had previously accepted a non-prone position. Nearly half of the infants (49.1%) were usually placed supine, 22.7% usually on the side, and 26.8% in variable positions of which 2.0% occasionally included prone. The side position was the least stable position. After the age of 1 week, 59.4% of infants had been found with their heads covered on at least one occasion. CONCLUSIONS: SIDS is rare when prone sleeping is avoided. Infants at the age of particular risk for SIDS may spontaneously turn from the side to the prone position, and they commonly slip under the bedding during sleep.

Abstract
The question as to whether abdominal obesity has an adverse effect on hip fracture remains unanswered. The purpose of this study was to investigate the associations of waist circumference, hip circumference, waist-hip ratio, and body mass index with incident hip fracture.
The data in this prospective study is based on Cohort of Norway, a population-based cohort established during 1994-2003. Altogether 19,918 women and 23,061 men aged 60-79 years were followed for a median of 8.1 years. Height, weight, waist and hip circumference were measured at baseline using standard procedures. Information on covariates was collected by questionnaires. Hip fractures (n = 1,498 in women, n = 889 in men) were identified from electronic discharge registers from all general hospitals in Norway between 1994 and 2008.
The risk of hip fracture decreased with increasing body mass index, plateauing in obese men. However, higher waist circumference and higher waist-hip ratio were associated with an increased risk of hip fracture after adjustment for body mass index and other potential confounders. Women in the highest tertile of waist circumference had an 86% (95% CI: 51-129%) higher risk of hip fracture compared to the lowest, with a corresponding increased risk in men of 100% (95% CI 53-161%). Lower body mass index combined with abdominal obesity increased the risk of hip fracture considerably, particularly in men.
Abdominal obesity was associated with an increased risk of hip fracture when body mass index was taken into account. In view of the increasing prevalence of obesity and the number of older people suffering osteoporotic fractures in Western societies, our findings have important clinical and public health implications.

Abstract
BACKGROUND: A high prevalence of impaired glucose tolerance and unknown type 2-diabetes in patients with coronary heart disease and no previous diagnosis of diabetes have been reported. The aims of the present study were to investigate the prevalence of abnormal glucose regulation (AGR) 3 months after an acute ST-elevation myocardial infarction (STEMI) in patients without known glucometabolic disturbance, to evaluate the reliability of a 75-g oral glucose tolerance test (OGTT) performed very early after an acute STEMI to predict the presence of AGR at 3 months, and to study other potential predictors measured in-hospital for AGR at 3 months. METHODS: This was an observational cohort study prospectively enrolling 224 STEMI patients treated with primary PCI. An OGTT was performed very early after an acute STEMI and was repeated in 200 patients after 3 months. We summarised the exact agreement observed, and assessed the observed reproducibility of the OGTTs performed in-hospital and at follow up. The patients were classified into glucometabolic categories defined according to the World Health Organisation criteria. AGR was defined as the sum of impaired fasting glucose, impaired glucose tolerance and type 2-diabetes. RESULTS: The prevalence of AGR at three months was 24.9% (95% CI 19.1, 31.4%), reduced from 46.9% (95% CI 40.2, 53.6) when measured in-hospital. Only, 108 of 201 (54%) patients remained in the same glucometabolic category after a repeated OGTT. High levels of HbA1c and admission plasma glucose in-hospital significantly predicted AGR at 3 months (p

Abstract
The objective was to investigate prevalence, estimate risk factors, and antenatal suspicion of abnormally invasive placenta (AIP) associated with laparotomy in women in the Nordic countries.
Population-based cohort study.
A 3-year Nordic collaboration among obstetricians to identify and report on uterine rupture, peripartum hysterectomy, excessive blood loss, and AIP from 2009 to 2012 The Nordic Obstetric Surveillance Study (NOSS).
In the NOSS study, clinicians reported AIP cases from maternity wards and the data were validated against National health registries.
Prevalence, risk factors, antenatal suspicion, birth complications, and risk estimations using aggregated national data.
A total of 205 cases of AIP in association with laparotomy were identified, representing 3.4 per 10 000 deliveries. The single most important risk factor, which was reported in 49% of all cases of AIP, was placenta praevia. The risk of AIP increased seven-fold after one prior caesarean section (CS) to 56-fold after three or more CS. Prior postpartum haemorrhage was associated with six-fold increased risk of AIP (95% confidence interval 3.7-10.9). Approximately 70% of all cases were not diagnosed antepartum. Of these, 39% had prior CS and 33% had placenta praevia.
Our findings indicate that a lower CS rate in the population may be the most effective way to lower the incidence of AIP. Focused ultrasound assessment of women at high risk will likely strengthen antenatal suspicion. Prior PPH is a novel risk factor associated with an increased prevalence of AIP.
An ultrasound assessment in women with placenta praevia or prior CS may double the awareness for AIP.

Abstract
A population-based case-control study was conducted in Sweden and Norway to analyse possible associations between breast cancer occurring before the age of 45 and several different characteristics of the women's reproductive life. A total of 422 (89.2%) of all eligible patients, and 527 (80.6%) of all eligible controls were interviewed. In univariate analyses, different characteristics of child-bearing (parity, age at first birth, years between last birth and diagnosis, duration of breast-feeding, and number of induced and spontaneous abortions), measures of the fertile or ovulating period (age at menarche, years between menarche and first pregnancy, and estimates of the menstruation span) and symptoms of anovulatory cycles or infertility were all seemingly unrelated to, or at most weakly associated with breast cancer. Adjustment for possible confounding factors in multivariate analyses resulted in largely unaltered risk estimates with odds ratios close to unity and without any significant trends when the exposure variables were studied in categorised or in continuous form. We conclude that reproductive factors did not explain the occurrence of breast cancer before the age of 45 in this population.

Abstract
In Western Norway, long-term follow up epidemiological studies have revealed significant increases in the incidence and prevalence rates of multiple sclerosis (MS) in stable populations, indicating the impact of exogenous factors. In this study 183 MS patients and 102 controls from high prevalence areas in Western Norway were investigated for human T-lymphotropic virus type I (HTLV-1) related sequences by polymerase chain reaction. Using primers targeting the gag, pol and env genes in the HTLV-1 provirus genome, no amplification products were detected in the 183 MS patients or 102 controls. The results strongly suggest that neither HTLV-1 nor a closely related retrovirus participate in the aetiology of MS.
