Abstract
BACKGROUND Knowledge regarding CNS pharmacokinetics of moxifloxacin is limited, with unknown consequences for patients with meningitis caused by bacteria resistant to beta-lactams or caused by TB. OBJECTIVE (i) To develop a novel porcine model for continuous investigation of moxifloxacin concentrations within brain extracellular fluid (ECF), CSF and plasma using microdialysis, and (ii) to compare these findings to the pharmacokinetic/pharmacodynamic (PK/PD) target against TB. METHODS Six female pigs received an intravenous single dose of moxifloxacin (6 mg/kg) similar to the current oral treatment against TB. Subsequently, moxifloxacin concentrations were determined by microdialysis within five compartments: brain ECF (cortical and subcortical) and CSF (ventricular, cisternal and lumbar) for the following 8 hours. Data were compared to simultaneously obtained plasma samples. Chemical analysis was performed by high pressure liquid chromatography with mass spectrometry. The applied PK/PD target was defined as a maximum drug concentration (Cmax):MIC ratio >8. RESULTS We present a novel porcine model for continuous in vivo CNS pharmacokinetics for moxifloxacin. Cmax and AUC0-8h within brain ECF were significantly lower compared to plasma and lumbar CSF, but insignificantly different compared to ventricular and cisternal CSF. Unbound Cmax:MIC ratio across all investigated compartments ranged from 1.9 to 4.3. CONCLUSION A single dose of weight-adjusted moxifloxacin administered intravenously did not achieve adequate target site concentrations within the uninflamed porcine brain ECF and CSF to reach the applied TB CNS target.

Abstract
STUDY QUESTION Are there some characteristics that render individuals more susceptible to report menstrual changes following the Coronavirus disease 2019 (COVID-19) vaccination? SUMMARY ANSWER We found that 30% of menstruating women reported menstrual changes following COVID-19 vaccination and several potential risk factors including stress, vaccine concerns, severe COVID-19 infection, and immediate vaccine symptoms were associated with these reports. WHAT IS KNOWN ALREADY Studies suggest that COVID-19 vaccination might temporarily prolong menstrual cycle length by less than 1 day. Specific characteristics may trigger menstrual changes in temporal relation to the vaccination simply by chance or render women more vigilant to potential menstrual changes after being vaccinated. However, research investigating potential risk factors for reporting menstrual changes following COVID-19 vaccination is limited. STUDY DESIGN, SIZE, DURATION A population-based Danish cohort study. Data were collected from May 2021 to December 2021 as a part of the BiCoVac Cohort with the aim of examining non-specific effects following COVID-19 vaccination. The main study population included 13 648 menstruating women aged 16-65 years who completed all surveys, received their first dose of a COVID-19 vaccine during the data collection period, and completed questions related to their menstrual cycle. PARTICIPANTS/MATERIALS, SETTING, METHODS Potential risk factors included 14 biological, physical, or psychological measures. Information on most potential risk factors was self-reported and collected before the participants' first COVID-19 vaccination. Information about any menstrual change following COVID-19 vaccination was self-reported at the end of the data collection period. Logistic regression analyses were used to estimate crude and adjusted odds ratios (ORs) with 95% CIs for the association between each potential risk factor and reporting menstrual changes following COVID-19 vaccination. MAIN RESULTS AND THE ROLE OF CHANCE Any menstrual change following COVID-19 vaccination was reported by 30% of menstruating women. Most of the potential risk factors were associated with reports of menstrual changes following COVID-19 vaccination. In particular, higher odds were found among women who reported ≥5 immediate vaccine symptoms; OR 1.67 [1.50-1.86], had had a prior severe COVID-19 infection; OR 2.17 [1.40-3.35], had a high-stress level at baseline; OR 1.67 [1.32-2.10], or were concerned about COVID-19 vaccines prior to vaccination; OR 1.92 [1.50-2.45]. Lower odds were found among women with regular menstrual cycles using hormonal contraception; OR 0.71 [0.65-0.78]. LIMITATIONS, REASONS FOR CAUTION We were unable to address the causal effect of COVID-19 vaccination on the reported menstrual changes, as information about menstrual changes was not available among non-vaccinated women. WIDER IMPLICATIONS OF THE FINDINGS The study identified several potential risk factors for reporting menstrual changes following COVID-19 vaccination. Further studies are needed to establish causal associations and the clinical impact of self-reported menstrual changes. STUDY FUNDING/COMPETING INTEREST(S) The BiCoVac data collection was funded by TrygFonden (id-number: 153678). No competing interests are declared. TRIAL REGISTRATION NUMBER N/A.

Abstract
INTRODUCTION There is sparse knowledge of immediate adverse reactions following COVID-19 vaccination. OBJECTIVE This study aimed to estimate the frequency and number of immediate adverse reactions following COVID-19 vaccination in a Danish population. METHODS The study used data from the Danish population-based cohort study BiCoVac. The frequencies of 20 self-reported adverse reactions were estimated for each vaccine dose stratified by sex, age, and vaccine type. Also, the distributions of number of adverse reactions following each dose were estimated stratified by sex, age, vaccine type, and prior COVID-19 infection. RESULTS A total of 889,503 citizens were invited and 171,008 (19 %) vaccinated individuals were included in the analysis. The most frequently reported adverse reaction following the first dose of COVID-19 vaccine was redness and/or pain at the injection site (20 %) while following the second and third dose, tiredness was the most frequently reported adverse reaction (22 % and 14 %, respectively). Individuals aged 26-35 years, females, and those with a prior COVID-19 infection were more likely to report adverse reactions compared with older individuals, males, and those with no prior COVID-19 infection, respectively. Following the first dose, individuals vaccinated with ChAdOx1-2 (AstraZeneca) reported more adverse reactions compared with individuals vaccinated with other vaccine types. Individuals vaccinated with mRNA-1273 (Moderna) reported more adverse reactions following the second and third dose compared with individuals vaccinated with BNT162b2 (Pfizer-BioNTech). CONCLUSION The frequency of immediate adverse reactions was highest among females and younger persons, however, most of the Danish citizens did not experience immediate adverse reactions following COVID-19 vaccination.

Abstract
Background:Sarcoidosis is characterized by granulomatous inflammation, which in rare cases can affect the central nervous system, neurosarcoidosis (NS).Objectives:The aim of this study was to estimate levels of cytokines, chemokines, and vascular biomarkers in patients with NS.Methods:In this observational, cross-sectional study, cerebrospinal fluid (CSF) and plasma were collected from biopsy-proven sarcoidosis patients with clinical suspicion of NS. They were categorized into either a NS group (n=14) or a non-NS group (n=5) depending on fulfilment of NS criteria. The results were compared to a healthy control group (HC, n=11). Samples were analysed with Electrochemiluminescence, Mesoscale®.Results:The level of INF γ was significantly higher in NS group compared to non-NS group in CSF (median 11.3 pg/mL vs. 3.3 pg/mL) and in plasma (median 21.6 pg/mL vs. 4.5 pg/mL)In CSF and not in plasma, the level differs significantly in NS group compared to non-NS group, IL12/IL23p40 (median 54.05 pg/mL vs. 3.61 pg/mL), IL16 (median 8.7 pg/mL vs. 4.3 pg/mL), IL17A (median 1.37 pg/mL vs. 0.19 pg/mL), TNF β (median 0.37 pg/mL vs. 0.02 pg/mL), IL8 (median 55.4 pg/mL vs. 37.8 pg/mL), CCL11 (median 36.1 pg/mL vs. 16.4 pg/mL, CCL26 (median 6.7 pg/mL vs. 3.7 pg/mL), CXCL10 (median 4981 pg/mL vs. 771 pg/mL), CCL13 (median 24.5 pg/mL vs. 10.0 pg/mL), CCL22 (median 129.8 pg/mL vs. 22.6 pg/mL), CCL3 (median 54.1 pg/mL vs. 20.7 pg/mL), CCL17 (median 54.0 pg/mL vs. 6.9 pg/mL), ICAM1 (median 13901 pg/mL vs. 7327 pg/ml), and VCAM1 (median 18594 pg/mL vs. 12132 pg/mL)A cut-off level for each cytokine was set at 20% above the maximum values of both non-NS group and HC. Using this, the ratio of patients in NS group over were:-INF γ, 57% had level over 6.2 pg/mL in CSF, and 50% had level over 21.6 pg/mL in plasma.-IL12/IL23p40, 71% had level over 16.7 pg/mL in CFS.-CXCL10, 79% had level over 1614 pg/mL in CFS.-CCL22, 79% had level over 49.8 pg/mL in CFS.Conclusion:In NS patients, INF γ was elevated in both CSF and plasma, and multiple cytokines, chemokinves and vascular biomarkers were elevated in CSF.Disclosure of Interests:Keld-Erik Byg: None declared, Zsolt Illes: None declared, Tobias Sejbaek Grant/research support from: Biogen, grants, outside the submitted work., Consultant of: Personal fees from Novartis, outside the submitted work., Astrid Kindt: None declared, Torkell Ellingsen: None declared, Helle Nielsen: None declared

Abstract
Background Death from bacterial meningitis is rarely attributed to the actual event causing death. The present study therefore categorized and characterized the cause and time of death due to bacterial meningitis. Methods In a cohort of patients > 15 years of age with community acquired bacterial meningitis the medical records were reviewed, and a clinical cause of death categorized into six main categories: 1) CNS complications, 2) Systemic complications, 3) Combination of systemic and CNS complications, 4) Sudden death, 5) Withdrawal of care, or 6) Unknown. Results We identified 358 patients of which 84 (23%) died in-hospital. Causes of death were ascribed to CNS complications in 43%, Systemic complications in 39%, Combined CNS and systemic complications in 4%, Sudden death in 7% and withdrawal of care in 5%. Brain herniation, circulatory failure, intractable seizures and other brain injury were the most common specific causes of death within 14 days from admission (55%). Conclusion Fatal complications due to the primary infection – meningitis - is most common within 14 days of admission. The diversity of complications causing death in meningitis suggest that determining the clinical cause of death is essential to the evaluation of novel treatment strategies.

Abstract
OBJECTIVES To examine the incidence and mortality of brain abscesses. METHODS We accessed nationwide population-based medical registries to obtain data for patients with first-time brain abscesses in Denmark from 1982 through 2016. Annual age- and sex-standardized incidence rates with 95% confidence intervals were calculated and compared by direct standardization. We used Cox regression to compute mortality rate ratios adjusted for age and year groups, sex and Charlson comorbidity index score. RESULTS We identified 1384 patients (37% female). The overall standardized incidence rate of brain abscess was 0.76 per 100 000 person-years (95% confidence interval 0.70-0.81). The incidence rates gradually increased from 0.60 during 1982-88 to 0.90 per 100 000 person-years during 2010-16, yielding an incidence rate ratio of 1.50 (95% confidence interval 1.26-1.79). This increase in incidence was most pronounced in the proportions of brain abscess patients >40 years of age and those with immuno-compromise. The 1-year mortality declined from 29% during 1982-88 to 20% during 2010-16, yielding an adjusted mortality rate ratio of 0.44 (95% confidence interval 0.31-0.63). Risk factors for death were advanced age, Charlson comorbidity index >0, immuno-compromised status and congenital heart disease. CONCLUSIONS The incidence of brain abscess in Denmark is low but increasing, especially in the elderly, along with an increasing proportion of brain abscess patients with immuno-compromise. The prognosis has improved during the last decades, but mortality remains high. Risk factors for death in our study were advanced age, presence of comorbidity, immuno-compromised status and congenital heart disease.

Abstract
OBJECTIVE We tested the ability of a type 1 diabetes (T1D) genetic risk score (GRS) to predict progression of islet autoimmunity and T1D in at-risk individuals. RESEARCH DESIGN AND METHODS We studied the 1,244 TrialNet Pathway to Prevention study participants (T1D patients' relatives without diabetes and with one or more positive autoantibodies) who were genotyped with Illumina ImmunoChip (median [range] age at initial autoantibody determination 11.1 years [1.2-51.8], 48% male, 80.5% non-Hispanic white, median follow-up 5.4 years). Of 291 participants with a single positive autoantibody at screening, 157 converted to multiple autoantibody positivity and 55 developed diabetes. Of 953 participants with multiple positive autoantibodies at screening, 419 developed diabetes. We calculated the T1D GRS from 30 T1D-associated single nucleotide polymorphisms. We used multivariable Cox regression models, time-dependent receiver operating characteristic curves, and area under the curve (AUC) measures to evaluate prognostic utility of T1D GRS, age, sex, Diabetes Prevention Trial-Type 1 (DPT-1) Risk Score, positive autoantibody number or type, HLA DR3/DR4-DQ8 status, and race/ethnicity. We used recursive partitioning analyses to identify cut points in continuous variables. RESULTS Higher T1D GRS significantly increased the rate of progression to T1D adjusting for DPT-1 Risk Score, age, number of positive autoantibodies, sex, and ethnicity (hazard ratio [HR] 1.29 for a 0.05 increase, 95% CI 1.06-1.6; P = 0.011). Progression to T1D was best predicted by a combined model with GRS, number of positive autoantibodies, DPT-1 Risk Score, and age (7-year time-integrated AUC = 0.79, 5-year AUC = 0.73). Higher GRS was significantly associated with increased progression rate from single to multiple positive autoantibodies after adjusting for age, autoantibody type, ethnicity, and sex (HR 2.27 for GRS >0.295, 95% CI 1.47-3.51; P = 0.0002). CONCLUSIONS The T1D GRS independently predicts progression to T1D and improves prediction along T1D stages in autoantibody-positive relatives.

Abstract
Effects of intravenous ioxilan, a new third generation non-ionic contrast medium, diatrizoate, iohexol and saline on urine profiles were compared. Albumin, glucose, sodium, phosphate, and the enzymes NAG, LDH and GGT were followed in 24 normal rats over 7 days. Diatrizoate significantly affected all profile components during the first two hours. Albuminuria was significantly greater after diatrizoate than after iohexol or ioxilan, and excretion of glucose, LDH and GGT was significantly higher than after ioxilan. Both iohexol and ioxilan increased the excretion of albumin, LDH and GGT, while iohexol also significantly increased excretion of glucose and sodium. There was a greater excretion of glucose and GGT after iohexol than after ioxilan. Saline did not induce any changes. At day 7, serum sodium, urea, creatinine, and albumin were normal for all test substances, and kidney histology revealed no difference between the groups of animals. It is thus concluded that both high osmolar ionic and low osmolar non-ionic contrast media may cause temporary glomerular and tubular dysfunction in rats. In this model, the kidney is affected most by diatrizoate, less by iohexol, and least by ioxilan.

Abstract
Diatrizoate, iohexol or ioxilan were injected intravenously in 18 rabbits. The contrast medium passage through the kidneys was recorded on digital subtraction images for the first 50 s followed by 100 mm exposures up to 15 min after injection. The renal area was measured planimetrically. Urine profiles (glucose, phosphate, LDH, GGT, NAG), blood profiles (potassium, urea) and the relative clearance of albumin and sodium were followed for 5 days and compared with a control group injected with saline. All kidneys were examined by light and immunofluorescence microscopy. All three contrast media produced excellent arteriograms and urograms. The three different contrast media caused a rapid increase of the kidney area within the first minute, reaching an average maximum of 10 to 12 per cent after 5 min, followed by a gradual decline. Contrary to expectations the increase in renal area was similar for all three contrast media, so hyperosmolality is no likely explanation of this phenomenon. None of the contrast agents caused significant changes in any of the profile components with one exception: the GGT excretion was significantly elevated during the first 24 h after diatrizoate administration as compared with the effect of saline. Light and immunofluorescence microscopy revealed no differences.

Abstract
Nine patients with myelodysplastic syndrome (MDS) were examined with magnetic resonance imaging and in vivo T1 relaxation time measurements of the vertebral bone marrow in a 1.5 tesla whole body scanner. Two patients underwent transformation to acute myeloid leukemia and were evaluated at follow-up examinations. At the time of diagnosis the T1 relaxation times of the vertebral bone marrow were significantly prolonged compared with normal values. The T1 relaxation times of the vertebral bone marrow in patients with MDS showed significantly lower values compared with patients with acute leukemia and did not differ from patients with polycythemia vera.

Abstract
OBJECTIVES Female gender has been suggested to be associated with poor outcome in patients with Staphylococcus aureus bacteraemia (SAB), but existing data remain sparse and conflicting. We investigated clinical outcomes in female and male patients with community-acquired (CA-) SAB. METHODS Population-based medical registers were used to conduct a cohort study of all adult patients with CA-SAB in northern Denmark, 2000-2011. Thirty-day mortality after CA-SAB for female and male patients was estimated by the Kaplan-Meier method. Using Cox proportional hazards regression, we computed hazard ratios (HRs) of death according to gender, overall and stratified by age groups, co-morbidity level, and selected major diseases while adjusting for potential confounders. Moreover, we estimated 30-day prevalence proportions for SAB-associated infective endocarditis and osteomyelitis by gender. RESULTS Among 2638 patients with CA-SAB, 1022 (39%) were female. Thirty-day mortality was 29% (n = 297) in female patients and 22% (n = 355) in male patients, yielding an adjusted HR (aHR) of 1.30 (95% CI, 1.11-1.53). This association appeared robust across age groups, whereas no consistent pattern was observed according to co-morbidity level. Compared with male patients, the prognostic impact of gender was most pronounced among female patients with diabetes (aHR 1.52; 95% CI 1.04-2.21)), and among female patients with cancer (aHR 1.40; 95% CI 1.04-1.90). The 30-day prevalence of infective endocarditis or osteomyelitis did not differ according to gender. CONCLUSION Female patients with CA-SAB experienced increased 30-day mortality compared with male patients. Gender should be considered in the triage and risk stratification of CA-SAB patients.

Abstract
Transmitted human immunodeficiency virus drug resistance in Europe is stable at around 8%. The impact of baseline mutation patterns on susceptibility to antiretroviral drugs should be addressed using clinical guidelines. The impact on baseline susceptibility is largest for nonnucleoside reverse transcriptase inhibitors. Background. Numerous studies have shown that baseline drug resistance patterns may influence the outcome of antiretroviral therapy. Therefore, guidelines recommend drug resistance testing to guide the choice of initial regimen. In addition to optimizing individual patient management, these baseline resistance data enable transmitted drug resistance (TDR) to be surveyed for public health purposes. The SPREAD program systematically collects data to gain insight into TDR occurring in Europe since 2001. Methods. Demographic, clinical, and virological data from 4140 antiretroviral-naive human immunodeficiency virus (HIV)–infected individuals from 26 countries who were newly diagnosed between 2008 and 2010 were analyzed. Evidence of TDR was defined using the WHO list for surveillance of drug resistance mutations. Prevalence of TDR was assessed over time by comparing the results to SPREAD data from 2002 to 2007. Baseline susceptibility to antiretroviral drugs was predicted using the Stanford HIVdb program version 7.0. Results. The overall prevalence of TDR did not change significantly over time and was 8.3% (95% confidence interval, 7.2%–9.5%) in 2008–2010. The most frequent indicators of TDR were nucleoside reverse transcriptase inhibitor (NRTI) mutations (4.5%), followed by nonnucleoside reverse transcriptase inhibitor (NNRTI) mutations (2.9%) and protease inhibitor mutations (2.0%). Baseline mutations were most predictive of reduced susceptibility to initial NNRTI-based regimens: 4.5% and 6.5% of patient isolates were predicted to have resistance to regimens containing efavirenz or rilpivirine, respectively, independent of current NRTI backbones. Conclusions. Although TDR was highest for NRTIs, the impact of baseline drug resistance patterns on susceptibility was largest for NNRTIs. The prevalence of TDR assessed by epidemiological surveys does not clearly indicate to what degree susceptibility to different drug classes is affected.

Abstract
BACKGROUND Hyponatraemia is a prognostic marker of increased mortality and morbidity in selected groups of hospitalised patients. The aim of the present study was to examine the prevalence and prognostic significance of hyponatraemia at hospital admission in an unselected population with a broad spectrum of medical and surgical diagnoses. METHODS Consecutive patients >40 years of age admitted to a general district hospital in Greater Copenhagen between 1 April 1998 and 31 March 1999. Median follow-up time was 5.16 years (range 0-4372 days). Plasma sodium measurements were available in 2960 patients, and hyponatraemia defined as P-Na(+) <137 mmol/L at hospital admission was present in 1105 (37.3 %) patients. RESULTS One-year mortality was higher for hyponatraemic patients than for normonatraemic patients: 27.5% versus 17.7%. Moreover, hyponatraemia was an independent predictor of short and long-term all-cause mortality after 1 year and after the entire observation period respectively: hazard ratio (HR) 1.6 (95 % confidence interval (CI) 1.4-1.9, P < 0.0001) and HR 1.4 (95 % CI 1.3-1.6, P < 0.0001). Patients with hyponatraemia had longer hospitalisations than patients with normonatraemia: 7.6 (±0.38) days vs 5.6 (±0.21) days, P < 0.001. There was no interaction between hyponatraemia at admission and any admission diagnoses (P > 0.05 for all interaction analyses). CONCLUSION Hyponatraemia is associated with increased all-cause mortality and longer admission length independently of diagnosis and clinical variables.

Abstract
Severe bacterial infections may have a prolonged negative effect on subsequent functional status and health-related quality of life. We studied hospitalized patients for changes in functional status and quality of life within 1 year of community-acquired bacteraemia in comparison to blood-culture-negative controls. In a prospectively conducted matched cohort study at Aalborg University Hospital, north Denmark, during 2011-2014, we included 71 medical inpatients with first-time community-acquired bacteraemia. For each bacteraemia patient, we matched one blood-culture-negative inpatient control on age and gender. Functional status and quality of life before and after hospitalization were assessed by Barthel-20 and EuroQol-5D questionnaires. We computed the 3-month and 1-year risk for any deterioration in Barthel-20 score and EuroQol-5D index score, and for a deterioration of ≥10 points in EuroQol-5D visual analogue scale score, and used regression analyses to assess adjusted risk ratios (RR) with 95% CIs. Compared with controls, bacteraemia was associated with an increased 3-month risk for deterioration in functional status as assessed by Barthel-20 score (14% versus 3% with deterioration, adjusted RR 5.1; 95% CI 1.2-22.3). The difference was less after 1 year (11% versus 7% with deterioration, adjusted RR 1.6; 95% CI 0.5-4.5). After 3 months, quality of life had become worse in 37% of bacteraemia patients and 28% of controls by EuroQol-5D index score (adjusted RR 1.3; 95% CI 0.8-2.1), with similar findings after 1 year and by visual analogue scale. In conclusion, community-acquired bacteraemia is associated with increased risk for subsequent deterioration in functional status compared with blood-culture-negative controls, and with a high risk for deterioration in quality of life.

Abstract
BACKGROUND The pattern recognition molecule pentraxin-3 (PTX3) is a novel potential marker of prognosis, as elevated levels are associated with both disease severity and mortality in patients with a wide range of conditions. However, the usefulness of PTX3 as a prognostic biomarker in a general hospital setting is unknown. PATIENTS AND METHODS The study cohort consisted of 1326 unselected, consecutive patients (age >40 years) admitted to a community hospital in Copenhagen, Denmark. Patients were followed until death or for a median of 11.5 years after admission. The main outcome measure was all-cause mortality. Serum samples collected from patients at admission and from 192 healthy control subjects were quantified for PTX3 level by enzyme-linked immunosorbent assay. RESULTS PTX3 was elevated in patients (median 3.7 ng mL(-1) , range 0.5-209.8) compared with healthy nonhospitalized subjects (median 3.5 ng mL(-1) , range 0.0-8.3; P = 0.0003). Elevated PTX3 levels, defined as above the 95th percentile of the concentration in healthy subjects, were associated with increased overall mortality during the study (P < 0.0001). This increase in mortality was greatest in the short term, with an unadjusted hazard ratio (HR) of 6.4 [95% confidence interval (CI) 3.8-11.0] at 28 days after admission, compared to 1.7 (95% CI 1.4-2.0) at the end of follow-up. These results were still significant after adjustment for age, gender and glomerular filtration rate: adjusted HR of 5.0 (95% CI 2.9-8.8) and 1.4 (95% CI 1.2-1.8), respectively. CONCLUSION These results suggest that PTX3 could be a widely applicable marker of short-term mortality in hospitalized patients and may be useful in the initial risk stratification.

Abstract
OBJECTIVES YKL-40 is an inflammatory biomarker associated with disease activity and mortality in patients with diseases characterized by inflammation and tissue remodelling. The aim of this study was to describe the prognostic value of YKL-40 in an unselected patient population. DESIGN In consecutive patients admitted to hospital during a 1-year period, blood was collected and information regarding final diagnosis and mortality was collected. Median follow-up time was 11.5 years. SETTING District hospital, Copenhagen, Denmark. PATIENTS A total of 1407 patients >40 years of age were admitted acutely. MAIN OUTCOME MEASURE All-cause mortality. RESULTS Median YKL-40 was increased in patients (157 μg L(-1) , range 13-7704 μg L(-1) ) compared to healthy controls (40 μg L(-1) , range 29-58 μg L(-1) ; P < 0.001). Patients with YKL-40 in the highest quartile had a hazard ratio (HR) of 7.1 [95% confidence interval (CI) 4.2-12.0] for all-cause mortality in the first year and 3.4 (95% CI 2.8-4.2) in the total study period, compared to those in the lowest quartile (HR = 1). The HR for death for all patients with YKL-40 above the normal age-corrected 95th percentile was 2.1 (95% CI 1.6-2.7) after 1 year and 1.5 (95% CI 1.3-1.7) during the total study period, compared to patients with YKL-40 below the age-corrected 95th percentile. The results of multivariable analysis showed that YKL-40 was an independent biomarker of mortality; this was most significant in the first year. YKL-40 was a marker of prognosis in all disease categories. The HR for death was increased in patients with YKL-40 above the normal age-corrected 95th percentile in healthy subjects independent of type of disease (all P < 0.001). CONCLUSION The level of YKL-40 at admission is a strong predictor of overall mortality, independent of diagnosis and could be useful as a biomarker in the acute evaluation of all patients.

Abstract
There are only sparse data on the short-term and medium-term clinical impacts of Campylobacter concisus infection. A clinical study was performed during a 2-year period to determine the clinical manifestations in C. concisus-positive adult patients. A case patient was defined as an adult patient (≥18 years) with a C. concisus-positive stool sample during the study period. Clinical data were obtained with use of a questionnaire supplemented with the patients' medical records, if any. The short-term and medium-term clinical manifestations in these patients were compared with those of patients with Campylobacter jejuni/Campylobacter coli infection. One hundred and seventy-four C. concisus patients and 196 C. jejuni/C. coli patients participated in the study. Patients with pre-existing inflammatory bowel disease or microscopic colitis or enteric co-infection were excluded from review of the clinical manifestations. Comparison of the short-term clinical manifestations in 139 C. concisus patients with those in 187 C. jejuni/C. coli patients showed a significantly lower prevalence of fever, chills, mucus and blood in stools, and weight loss. However, 80% of C. concisus patients, but only 32% of C. jejuni/C. coli patients, had diarrhoea for >2 weeks. After a 6-month follow-up period, 12% of C. concisus patients were diagnosed with microscopic colitis, whereas no C. jejuni/C. coli patients were diagnosed with non-infective colitis. Irritable bowel symptoms were common in both groups at follow-up. C. concisus infection seems to cause a milder course of acute gastroenteritis than C. jejuni/C. coli infection, but is associated with more prolonged diarrhoea.

Abstract
BACKGROUND Allergen epitope characterization provides valuable information useful for the understanding of proteins as food allergens. It is believed that IgE epitopes in general are conformational, nevertheless, for food allergens known to sensitize through the gastrointestinal tract linear epitopes have been suggested to be of great importance. OBJECTIVE The aim of this study was to identify IgE specific epitopes of intact and digested Ara h 1, and to compare epitope patterns between humans and rats. METHODS Sera from five peanut allergic patients and five Brown Norway rats were used to identify intact and digested Ara h 1-specific IgE epitopes by competitive immunoscreening of a phage-displayed random hepta-mer peptide library using polyclonal IgE from the individual sera. The resulting peptide sequences were mapped on the surface of a three-dimensional structure of the Ara h 1 molecule to mimic epitopes using a computer-based algorithm. RESULTS Patients as well as rats were shown to have individual IgE epitope patterns. All epitope mimics were conformational and found to cluster into three different areas of the Ara h 1 molecule. Five epitope motifs were identified by patient IgE, which by far accounted for most of the eluted peptide sequences. Epitope patterns were rather similar for both intact and digested Ara h 1 as well as for humans and rats. CONCLUSIONS Individual patient specific epitope patterns have been identified for the major allergen Ara h 1. IgE binding epitopes have been suggested as biomarkers for persistency and severity of food allergy, wherefore recognition of particular epitope patterns or motifs could be a valuable tool for prevention, diagnosis, and treatment of food allergy.

Abstract
The incidence of non-thermophilic Campylobacter species was assessed in an unselected population-based study in a mixed urban and rural community in North Jutland, Denmark. In a 2-year study period, 11,314 faecal samples from 8302 patients with gastroenteritis were cultured with supplement of the filter method. We recovered a high incidence of Campylobacter concisus (annual incidence 35/100,000 inhabitants), almost as high as the common Campylobacter jejuni/coli. In contrast, there was a very low incidence of other non-thermophilic Campylobacter species, such as Campylobacter upsaliensis. Campylobacter concisus was, unlike C. jejuni/coli, found more frequently among small children (<1 year) and the elderly (≥ 65 years). Around 10% of the patients with C. consisus had co-infections dominated by Clostridium difficile and Salmonella enterica, whereas co-infections occurred in about 5% of C. jejuni/coli patients. We observed a seasonal variation in C. jejuni/coli with a peak incidence in late summer months and autumn, whereas there was an almost constant monthly prevalence of C. concisus. Among patients participating in a questionnaire sub-study, there was a higher degree of close contacts with animals, especially dogs, as well as a higher travel exposure among C. jejuni/coli patients compared with C. concisus patients. We did not culture any C. concisus in stool samples from a small cohort of healthy individuals. Future studies have to focus on the clinical follow-up and the long-term risk of inflammatory bowel diseases in C. concisus-positive patients. We conclude that there is a high incidence of C. concisus in Denmark.

Abstract
OBJECTIVE The aim of the study was to compare changes in bone mineral density (BMD) over 144 weeks in HIV-infected patients initiating nucleoside reverse transcriptase inhibitor (NRTI)-sparing or protease inhibitor-sparing highly active antiretroviral therapy (HAART). METHODS Sixty-three HAART-naïve patients were randomized to zidovudine/lamivudine+efavirenz or lopinavir/ritonavir+efavirenz. We performed dual energy X-ray absorptiometry (DEXA) at baseline and at weeks 24, 48, 96 and 144 to evaluate lumbar spine and femoral neck (hip) BMD. RESULTS At baseline, 33 patients (55.9%) had low BMD (T-score < -1.0) and of these eight had osteoporosis (T-score < -2.5). Spine BMD declined in both arms until week 24, before stabilizing. In the NRTI-sparing arm, the mean percentage change from baseline was -2.7% [95% confidence interval (CI) -3.9 to -1.4] at week 24 and -2.5% (95% CI -5.4 to 0.3) at week 144, compared with -3.2% (95% CI -4.4 to -2.1) and -1.9% (95% CI -3.5 to -0.3) in the protease inhibitor-sparing arm. Hip BMD declined until week 48 before stabilizing. In the NRTI-sparing arm, BMD had decreased by -5.1% (95% CI -7.1 to -3.1) at week 48 and -4.5% (95% CI -6.9 to -2.1) at week 144, compared with -6.1% (95% CI -8.2 to -4.0) and -5.0% (95% CI -6.8 to -3.1) in the protease inhibitor-sparing arm. There were no significant differences between arms. Low baseline CD4 cell count was independently associated with spine (P=0.007) and hip (P=0.04) BMD loss and low body mass index with hip BMD loss (P=0.03). CONCLUSION Spine and hip BMD declined rapidly 24 to 48 weeks after initiating HAART, independent of the assigned drug class, but thereafter BMD values remained stable.

Abstract
BACKGROUND Population-based data on the early postoperative outcome after surgery for gastric cancer are very sparse. We examined the development in the quality of surgery and early postoperative outcomes in Denmark following centralization of gastric cancer surgery and implementation of national clinical guidelines. METHODS All patients in Denmark who underwent resection with curative intent for gastric cancer between 1st July 2003 and 31st December 2008 in one of five university hospitals were registered in a national database. Data on surgical quality and mortality were obtained from the database and compared with the results from the period before centralization (1999-2003). RESULTS A total of 416 patients underwent resection in the study period. The risk of anastomotic leakages for the whole period was 5.0% (95%CI; 3.2-7.7) compared to 6.1% (95%CI; 4.3-8.6) before centralization, whereas the 30-days hospital mortality was 2.4% (95%CI; 1.2-4.4) compared to 8.2% (95%CI; 6.0-10.4) before centralization. In addition, the percentage of patients with at least 15 lymph nodes removed increased during the study period from 19 in 2003 to 76 in 2008. CONCLUSIONS Centralization of gastric cancer surgery in Denmark and implementation of national clinical guidelines monitored by a national database was associated with improvements in surgical quality and substantially lower in-hospital mortality.

Abstract
OBJECTIVE Comorbidity has a major impact on short-term and long-term survival of colorectal cancer (CRC) and many CRC patients suffer from comorbidities. Mortality rates for comorbidities like cardio-respiratory diseases exhibit distinct seasonal variations with highest rates in the winter. Therefore, we hypothesized some seasonal variation in 30-day mortality after surgery for CRC as well. METHOD In a nationwide study, we examined the seasonal pattern in 30-day mortality after surgery for CRC from 1996 to 2006. We identified 33 556 CRC patients in the Danish hospital discharge registries. Monthly 30-day mortality rates were calculated and we constructed a fitted curve of the monthly mortality rates using a periodic regression model. We stratified the analyses for tumour site, urgency of surgery for colon cancer and the level of comorbidity based on American Society of Anaesthesiologists (ASA) score. RESULTS The overall 30-day mortality was 8.7% [95% confidence interval 8.4-9.0%). Significant seasonal variation in monthly 30-day mortality could not be identified. For colon cancer, a nonsignificant increase was seen in July. An even higher increase in July was observed for CRC patients with moderate or severe comorbidity (ASA score >or= III), but was also nonsignificant. CONCLUSION Although comorbidity is a well-known negative predictor of short-term survival of CRC, monthly 30-day mortality after surgery for CRC did not exhibit seasonal variation like that observed for comorbid conditions such as cardio-respiratory diseases.

Abstract
OBJECTIVE To determine the prevalence of and independent factors associated with joint involvement in a large population of patients with systemic sclerosis (SSc). METHODS This study was cross-sectional, based on data collected on patients included in the European League Against Rheumatism (EULAR) Scleroderma Trials and Research (EUSTAR) registry. We queried this database to extract data regarding global evaluation of patients with SSc and the presence of any clinical articular involvement: synovitis (tender and swollen joints), tendon friction rubs (rubbing sensation detected as the tendon was moved), and joint contracture (stiffness of the joints that decreased their range of motion). Overall joint involvement was defined by the occurrence of synovitis and/or joint contracture and/or tendon friction rubs. RESULTS We recruited 7286 patients with SSc; their mean age was 56 +/- 14 years, disease duration 10 +/- 9 years, and 4210 (58%) had a limited cutaneous disease subset. Frequencies of synovitis, tendon friction rubs, and joint contractures were 16%, 11%, and 31%, respectively. Synovitis, tendon friction rubs, and joint contracture were more prevalent in patients with the diffuse cutaneous subset and were associated together and with severe vascular, muscular, renal, and interstitial lung involvement. Moreover, synovitis had the highest strength of association with elevated acute-phase reactants taken as the dependent variable. CONCLUSION Our results highlight the striking level of articular involvement in SSc, as evaluated by systematic examination in a large cohort of patients with SSc. Our data also show that synovitis, joint contracture, and tendon friction rubs are associated with a more severe disease and with systemic inflammation.

Abstract
Lymphogranuloma venereum (LGV) is a sexually transmitted disease (STD) caused by serovars L1-L3 of Chlamydia trachomatis. Rare in the western world prior to 2003, different outbreaks or clusters of LGV have been reported in Europe, North America and Australia among men who have sex with men (MSM) over the past few years. The majority were HIV infected MSM with high-risk sexual behaviour and a high rate of concomitant STD, including hepatitis C. Most of them presented with a proctitis syndrome and only a few with the classical bubonic form. A previously non-described serovar, L2b, has been identified as the main causative agent of the epidemic. A delay in diagnosis has been the rule because of the misleading symptomatology of LGV proctitis, the unfamiliarity of the disease to physicians, and the lack of a routine diagnostic test for LGV serovars. It is crucial to increase the awareness of the disease among physicians for prompt diagnosis and treatment, to avoid complications, and to stop ongoing transmission. It has additional public health implications since LGV may facilitate the transmission and acquisition of HIV and other STD.

Abstract
An inception cohort of patients with systemic lupus erythematosus from 14 European centres was followed for up to 5 years in order to describe the current early disease course. At inclusion patients (n = 200, 89% female, mean age 35 years, 97% Caucasian, mean SLEDAI 12.2) fulfilled a mean of 6.5 ACR classification criteria. The most prevalent criteria were antinuclear Ab presence (97%) followed by anti-dsDNA Ab (74%), arthritis (69%), leukocytopenia (54%) and malar rash (53%), antiphospholipid Ab (48%) and anti-synovial membrane Ab (21.6%). Clinical signs of lupus nephritis (LN) were present in 39% with biopsy-confirmed LN seen in 25%. Frequent additional findings were hypocomplementaemia (54%), anti-SSA Ab (49%), alopecia (26%) and Raynaud’s phenomenon (31%). There were few regional differences in disease presentation and management. One and 5-year survival rates were 99% and 97% respectively. During the mean follow-up of 4.1 years 25% entered a state of early disease quiescence by global physician assessment, but the overall risk of subsequent flare was 60%. Maximum SLEDAI scores decreased over time, but 45% of patients accrued damage (SDI ≥1) for which baseline presence of proteinuria and persistent disease activity were independent predictors. The results indicate minor differences in SLE presentation and treatment within various regions of Europe and a high diagnostic reliance on anti-dsDNA Ab. Despite early reductions in disease activity and improved mortality, the risk for disease flare and damage development is, however, still substantial, especially in patients not entering an early remission.

Abstract
Acute hepatitis C virus (HCV) infection may lead to chronic HCV-infection with detectable HCV RNA or to spontaneous clearance with no HCV RNA, but detectable HCV antibodies. It is unknown whether HCV RNA status is associated with mortality in HIV-infected injection drug users (IDUs). We conducted a nationwide population-based cohort study to examine the impact of HCV RNA status on overall and cause-specific mortality in HIV-infected IDUs. We computed cumulative mortality and used Cox Regression to estimate mortality rate ratios (MRR). We identified 392 HIV-infected patients of whom 284 (72%) had chronic HCV-infection (HCV RNA positive patients) and 108 (28%) had cleared the HCV-infection (HCV RNA negative patients). During 1286 person-years of observation (PYR), 157 persons died (MR = 122/1000 PYR, 95% CI: 104-143). The estimated 5-year probabilities of survival were 0.58 (95% CI: 0.51-0.65) in the chronically HCV-infected and 0.52 (95% CI: 0.40-0.63) in the cleared HCV group. Chronic HCV-infection was not associated with overall mortality: MRR 0.85, 95% CI: 0.59-1.21. In HIV-infected Danish IDUs, chronic HCV-infection is not associated with increased mortality compared to patients who have cleared the infection.

Abstract
Invasive disease as a result of Campylobacter is rarely reported. We reviewed 46 cases of blood stream infection with Campylobacter in a Danish population with complete follow-up. The incidence was 2.9 per 1 million person-years with a peak incidence in the age group above 80 years. In the population, the ratio of notified bacteraemia/enteritis patients with Campylobacter infection was 0.004. Patients with bacteraemia were older and had higher comorbidity, e.g. alcoholism, immunosuppression, previous gastrointestinal surgery or HIV infection. We found 26% of blood isolates resistant to ciprofloxacin. The length of hospitalization was significantly longer in bacteraemia patients, whereas the outcome was favourable with 28-day mortality of 4% in bacteraemia patients and 1% in enteritis patients. None of the bacteraemia patients relapsed within 365-day follow-up.

Abstract
The role of bacterial genes in the determination of the clinical spectrum of Campylobacter jejuni infection is unclear. We compared clinical isolates from invasive blood-stream infection with stool isolates from gastroenteritis and found no association of the putative virulence genes iam, capA, virB and cdtB with clinical presentation.

Abstract
Until recently, Q fever was notified in very low numbers annually in Denmark and it was always considered to be acquired abroad. Preliminary reports now describe Coxiella burnetii in milk samples from Danish dairy cattle. Serum samples of a large cohort of farmers, veterinarians, inseminators and hoof trimmers, all having occupational contact with dairy cattle, were tested for the presence of IgG to phase I and phase II antigens of C. burnetii. In 39 of 359 individuals studied (11%), the presence of antibodies to C. burnetii was found. Veterinarians had the highest seropositivity rate (36%). This survey suggests that C. burnetii is a recently recognized domestic infection in Denmark and that risk of infection is associated with occupation.
