Abstract
OBJECTIVES To examine potential deteriorations in mental health and well-being in the first COVID-19 pandemic year compared with the previous decade focusing on the following vulnerable subgroups in Germany: women with minor children in the household, those living without a partner, younger and older adults, those in a precarious labour market situation, immigrants and refugees, and those with pre-existing physical or mental health risks. DESIGN Analyses of secondary longitudinal survey data using cluster-robust pooled ordinary least squares models. PARTICIPANTS More than 20 000 individuals (aged 16+ years) in Germany. PRIMARY AND SECONDARY OUTCOME MEASURES Mental Component Summary Scale (MCS) of the 12-item Short-Form Health Survey measuring mental health-related quality of life, single item on life satisfaction (LS). RESULTS We find a decline in the average MCS in the 2020 survey that is not particularly striking in the overall time course, still resulting in a mean score below those of all preceding waves since 2010. We find no change in LS from 2019 to 2020 against the background of a general upward trend. Regarding vulnerability factors, only the results on age and parenthood are partially in line with our expectations. In 2020, LS declined among the youngest adults; MCS declined among mothers (and women and men without children) but not fathers. Unlike respective comparison groups, refugees, those unemployed before the pandemic and those with pre-existing mental health risks experienced no MCS declines in 2020, whereas persons living without a partner, the eldest, and those with pre-existing health risks exhibited continued increases in LS. CONCLUSIONS There is no evidence for substantial breakdowns in mental health or subjective well-being in the first pandemic year in the German population or its subgroups, particularly when considering developments of the previous decade. Since the majority of hypothesised vulnerable groups to pandemic stressors showed more stable MCS and LS, our results warrant further study.

Abstract
This study explores how researchers' analytical choices affect the reliability of scientific findings. Most discussions of reliability problems in science focus on systematic biases. We broaden the lens to emphasize the idiosyncrasy of conscious and unconscious decisions that researchers make during data analysis. We coordinated 161 researchers in 73 research teams and observed their research decisions as they used the same data to independently test the same prominent social science hypothesis: that greater immigration reduces support for social policies among the public. In this typical case of social science research, research teams reported both widely diverging numerical findings and substantive conclusions despite identical start conditions. Researchers' expertise, prior beliefs, and expectations barely predict the wide variation in research outcomes. More than 95% of the total variance in numerical results remains unexplained even after qualitative coding of all identifiable decisions in each team's workflow. This reveals a universe of uncertainty that remains hidden when considering a single study in isolation. The idiosyncratic nature of how researchers' results and conclusions varied is a previously underappreciated explanation for why many scientific hypotheses remain contested. These results call for greater epistemic humility and clarity in reporting scientific findings.

Polyelectrolyte complexes (PECs) have been used as the matrix of solid foams for drug delivery. This study aimed at investigating the effect of graphene oxide (GO) and the composition of excipients in chitosan/alginate-based buccal foams on the clotrimazole release and antifungal activities. The investigation has been focused on the interactions of the drug with excipients in the foams, and the changes of ionization degree upon exposure to various media are discussed. The solid foams were prepared by mixing the excipients and clotrimazole via probe sonication, followed by a freeze-drying method. The pH values of the formulations were measured during the foam preparation process to estimate the ionization degree of clotrimazole and the other excipients. The foam matrix was the PECs between the cationic chitosan and anionic alginate. The mechanical strength of clotrimazole-loaded foams was lower than that of drug-free foams due to the positively charged clotrimazole interacting with the anionic alginate and interfering the PECs between chitosan and alginate. Addition of GO in the clotrimazole-loaded matrix made the foams mechanically stronger and contributed to a faster release of clotrimazole from the buccal foams by disrupting the electrostatic interactions between alginate and clotrimazole. However, addition of 1 wt% GO in the formulations didn't affect the antifungal activity of clotrimazole-loaded foams significantly. A lower amount GO in the formulation may be required for enhancing the antifungal effect, which should be further investigated in future.

Abstract
A diffuse flux of astrophysical neutrinos above 100 TeV has been observed at the IceCube Neutrino Observatory. Here we extend this analysis to probe the astrophysical flux down to 35 TeV and analyze its flavor composition by classifying events as showers or tracks. Taking advantage of lower atmospheric backgrounds for showerlike events, we obtain a shower-biased sample containing 129 showers and 8 tracks collected in three years from 2010 to 2013. We demonstrate consistency with the (fe:fμ:fτ)⊕≈(1:1:1)⊕ flavor ratio at Earth commonly expected from the averaged oscillations of neutrinos produced by pion decay in distant astrophysical sources. Limits are placed on nonstandard flavor compositions that cannot be produced by averaged neutrino oscillations but could arise in exotic physics scenarios. A maximally tracklike composition of (0:1:0)⊕ is excluded at 3.3σ, and a purely showerlike composition of (1:0:0)⊕ is excluded at 2.3σ.

Abstract
We present the development and application of a generic analysis scheme for the measurement of neutrino spectra with the IceCube detector. This scheme is based on regularized unfolding, preceded by an event selection which uses a Minimum Redundancy Maximum Relevance algorithm to select the relevant variables and a random forest for the classification of events. The analysis has been developed using IceCube data from the 59-string configuration of the detector. 27,771 neutrino candidates were detected in 346 days of livetime. A rejection of 99.9999 % of the atmospheric muon background is achieved. The energy spectrum of the atmospheric neutrino flux is obtained using the TRUEE unfolding program. The unfolded spectrum of atmospheric muon neutrinos covers an energy range from 100 GeV to 1 PeV. Compared to the previous measurement using the detector in the 40-string configuration, the analysis presented here, extends the upper end of the atmospheric neutrino spectrum by more than a factor of two, reaching an energy region that has not been previously accessed by spectral measurements.

Abstract
A search for high-energy neutrinos interacting within the IceCube detector between 2010 and 2012 provided the first evidence for a high-energy neutrino flux of extraterrestrial origin. Results from an analysis using the same methods with a third year (2012-2013) of data from the complete IceCube detector are consistent with the previously reported astrophysical flux in the 100 TeV-PeV range at the level of 10(-8) GeV cm-2 s-1 sr-1 per flavor and reject a purely atmospheric explanation for the combined three-year data at 5.7σ. The data are consistent with expectations for equal fluxes of all three neutrino flavors and with isotropic arrival directions, suggesting either numerous or spatially extended sources. The three-year data set, with a live time of 988 days, contains a total of 37 neutrino candidate events with deposited energies ranging from 30 to 2000 TeV. The 2000-TeV event is the highest-energy neutrino interaction ever observed.

Abstract
We report on results of an all-sky search for high-energy neutrino events interacting within the IceCube neutrino detector conducted between May 2010 and May 2012. The search follows up on the previous detection of two PeV neutrino events, with improved sensitivity and extended energy coverage down to about 30 TeV. Twenty-six additional events were observed, substantially more than expected from atmospheric backgrounds. Combined, both searches reject a purely atmospheric origin for the 28 events at the 4σ level. These 28 events, which include the highest energy neutrinos ever observed, have flavors, directions, and energies inconsistent with those expected from the atmospheric muon and neutrino backgrounds. These properties are, however, consistent with generic predictions for an additional component of extraterrestrial origin.

Abstract
We present the first statistically significant detection of neutrino oscillations in the high-energy regime (>20 GeV) from an analysis of IceCube Neutrino Observatory data collected in 2010 and 2011. This measurement is made possible by the low-energy threshold of the DeepCore detector (~20 GeV) and benefits from the use of the IceCube detector as a veto against cosmic-ray-induced muon background. The oscillation signal was detected within a low-energy muon neutrino sample (20-100 GeV) extracted from data collected by DeepCore. A high-energy muon neutrino sample (100 GeV-10 TeV) was extracted from IceCube data to constrain systematic uncertainties. The disappearance of low-energy upward-going muon neutrinos was observed, and the nonoscillation hypothesis is rejected with more than 5σ significance. In a two-neutrino flavor formalism, our data are best described by the atmospheric neutrino oscillation parameters |Δm(32)(2)|=(2.3(-0.5)(+0.6))×10(-3) eV(2) and sin(2)(2θ(23))>0.93, and maximum mixing is favored.

Abstract
We report on the observation of two neutrino-induced events which have an estimated deposited energy in the IceCube detector of 1.04±0.16 and 1.14±0.17 PeV, respectively, the highest neutrino energies observed so far. These events are consistent with fully contained particle showers induced by neutral-current ν(e,μ,τ) (ν(e,μ,τ)) or charged-current ν(e) (ν(e)) interactions within the IceCube detector. The events were discovered in a search for ultrahigh energy neutrinos using data corresponding to 615.9 days effective live time. The expected number of atmospheric background is 0.082±0.004(stat)(-0.057)(+0.041)(syst). The probability of observing two or more candidate events under the atmospheric background-only hypothesis is 2.9×10(-3) (2.8σ) taking into account the uncertainty on the expected number of background events. These two events could be a first indication of an astrophysical neutrino flux; the moderate significance, however, does not permit a definitive conclusion at this time.

Abstract
We report the first measurement of the atmospheric electron neutrino flux in the energy range between approximately 80 GeV and 6 TeV, using data recorded during the first year of operation of IceCube's DeepCore low-energy extension. Techniques to identify neutrinos interacting within the DeepCore volume and veto muons originating outside the detector are demonstrated. A sample of 1029 events is observed in 281 days of data, of which 496±66(stat)±88(syst) are estimated to be cascade events, including both electron neutrino and neutral current events. The rest of the sample includes residual backgrounds due to atmospheric muons and charged current interactions of atmospheric muon neutrinos. The flux of the atmospheric electron neutrinos is consistent with models of atmospheric neutrinos in this energy range. This constitutes the first observation of electron neutrinos and neutral current interactions in a very large volume neutrino telescope optimized for the TeV energy range.

Abstract
We have performed a search for muon neutrinos from dark matter annihilation in the center of the Sun with the 79-string configuration of the IceCube neutrino telescope. For the first time, the DeepCore subarray is included in the analysis, lowering the energy threshold and extending the search to the austral summer. The 317 days of data collected between June 2010 and May 2011 are consistent with the expected background from atmospheric muons and neutrinos. Upper limits are set on the dark matter annihilation rate, with conversions to limits on spin-dependent and spin-independent scattering cross sections of weakly interacting massive particles (WIMPs) on protons, for WIMP masses in the range 20-5000 GeV/c2. These are the most stringent spin-dependent WIMP-proton cross section limits to date above 35 GeV/c2 for most WIMP models.

Abstract
The in utero origins of breast cancer are an increasing focus of research. However, the long time period between exposure and disease diagnosis, and the lack of standardized perinatal data collection makes this research challenging. We assessed perinatal factors, as proxies for in utero exposures, and breast cancer risk using pooled, population-based birth and cancer registry data. Birth registries provided information on perinatal exposures. Cases were females born in Norway, Sweden or Denmark who were subsequently diagnosed with primary, invasive breast cancer (n = 1419). Ten controls for each case were selected from the birth registries matched on country and birth year (n = 14,190). Relative risks (RRs) and 95% confidence intervals (CIs) were estimated using unconditional regression models. Breast cancer risk rose 7% (95% CI 2-13%) with every 500 g (roughly 1 s.d.) increase in birth weight and 7% for every 1 s.d. increase in birth length (95% CI 1-14%). The association with birth length was attenuated after adjustment for birth weight, while the increase in risk with birth weight remained with adjustment for birth length. Ponderal index and small- and large-for-gestational-age status were not better predictors of risk than either weight or length alone. Risk was not associated with maternal education or age, gestational duration, delivery type or birth order, or with several pregnancy complications, including preeclampsia. These data confirm the positive association between birth weight and breast cancer risk. Other pregnancy characteristics, including complications such as preeclampsia, do not appear to be involved in later breast carcinogenesis in young women.

Abstract
Objective Invasive bladder cancer (IBC) is a common urological malignancy accounting for 4%–5% of all cancers in Denmark. Our aim was to examine possible changes in short- and long-term survival of patients with IBC during 1998–2009. Study design and setting Data on all patients (N = 4032) with an incident diagnosis of IBC within a population of 1.8 million were retrieved from the Danish National Registry of Patients from 1998 to 2009. We computed survival after 1, 3, and 5 years, stratified by age and gender, and estimated mortality rate ratios (MRR) using Cox proportional hazard regression to compare mortality over time, controlling for age and gender. Data on tumor stage or histology were not included. Results During the study period, the annual numbers of incident IBC patients remained stable. The median age was 74 years in each of the four 3-year periods in the study. The survival was relatively stable during the first three periods, whilst data from the last period showed modest improvement. The overall 1-year survival increased from 68% in 1998–2000 to 70% in 2007–2009, corresponding to an age and gender adjusted MRR of 0.89 (95% confidence interval [CI] 0.76–1.03). The 3- and 5-year survival was predicted to increase from 44% to 49% and from 35% to 40% respectively. This corresponded to a 3-year age and gender adjusted MRR of 0.87 (95% CI 0.77–0.98) and a 5-year MRR of 0.88 (95% CI 0.79–0.99). The 1-, 3-, and 5-year survival increased for men in all age groups (<70 years, 70–79 years, ≥80 years) and in women only in the 70–79-year age group. Conclusion The survival of IBC patients increased slightly in northern and central Denmark in the 1998–2009 period.

Abstract
IceCube has become the first neutrino telescope with a sensitivity below the TeV neutrino flux predicted from gamma-ray bursts if gamma-ray bursts are responsible for the observed cosmic-ray flux above 10(18) eV. Two separate analyses using the half-complete IceCube detector, one a dedicated search for neutrinos from pγ interactions in the prompt phase of the gamma-ray burst fireball and the other a generic search for any neutrino emission from these sources over a wide range of energies and emission times, produced no evidence for neutrino emission, excluding prevailing models at 90% confidence.

Abstract
ABSTRACTThe similarity of patterns formed in non-equilibrium growth processes in physics, chemistry and biology is conspicuous and many attempts have been made to discover common mechanisms underlying their growth. The central question in this context is what causes some patterns to be dendritic, as e.g. snowflakes, while others grow fractal (randomly ramified). Here we report a crossover from fractal to dendritic patterns for growth in two dimensions: the diffusion limited aggregation of Ag atoms on a Pt(111) surface as observed by means of variable temperature STM. The microscopic mechanism of dendritic growth can be analyzed for the present system. It originates from the anisotropy of the diffusion of adatoms at corner sites which is linked to the trigonal symmetry of the substrate. This corner diffusion is observed to be active as soon as islands form, therefore, the classical DLA clusters with the hit and stick mechanism do not form. The ideas on the mechanism for dendritic growth have been verified by kinetic Monte-Carlo simulations which are in excellent agreement with experiment.

Abstract
The single bile duct cannulated rat model was used for short-term intestinal absorption studies. Rats were randomly assigned to three groups: (A) bile duct cannulated, (B) control laparotomy and (C) no treatment. The body weight and health of the rats were monitored before and until day 5 after surgery, while bile flow was measured in group A on day 2. On the fifth day, tail vein blood was harvested, and alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase and total bilirubin were quantified. Analysis of variance showed no significant difference between the groups for these parameters. This study demonstrated the suitability of a surgical rat model feasible for evaluation of the impact of bile in pharmacokinetic studies.

Abstract
Abstract
Background Breast cancer (BrCa) is the most commonly diagnosed cancer among women in the industrialized world. More than half of women presenting with metastatic BrCa develop bone metastases. Bone metastases increase the risk of skeletal-related events (SREs), defined as radiation to bone, pathologic fractures, spinal cord compression, bone surgery, or altered antineoplastic therapy to treat bone pain. Both bone metastases and SREs are associated with unfavorable prognosis and greatly affect quality of life. To date, the epidemiology of the subgroup of BrCa patients who develop bone metastases and/or SREs has not been well-characterized. Our objective was to estimate the one- and five-year incidence of bone metastases and SREs in a large population cohort of newly-diagnosed BrCa patients in Denmark (population ∼ 5.4 million inhabitants). Methods We identified women diagnosed with BrCa (International Classification of Diseases, 10th Revision (ICD-10) code C50.x.) from January 1, 1999 through December 31, 2007, with follow-up through April 2008. We retrieved this data from Denmark's National Registry of Patients (NRP), which includes records from all Danish hospitals. We also identified bone metastases (ICD-10 code C79.5) and recorded SREs. The Kaplan-Meier method was used to estimate time to bone metastases and time to first SRE. We also calculated 1- and 5-year incidence rates (IR) of bone metastases and first SRE in newly-diagnosed BrCa patients. Results We identified 35,941 BrCa patients from the NRP. The median age at diagnosis was 62 years (range, 18-104 years). A total of 1,494 (4%) patients developed bone metastases during follow-up, and of these, 712 developed an SRE. The distribution of SREs by type were 394 (55%) with radiation to the bone, 133 (19%) with pathological or osteoporotic fracture, 42 (6%) with bone surgery, and 143 (20%) with spinal cord compression. The 1-year IR of bone metastases was 13.7 [95% confidence interval (CI): 12.5-15.0] per 1000 person-years (P-Y). The 1-year IR of SREs among patients with bone metastases was 55 times that of the 1-year IR of bone metastases in BrCa patients at 759.2 (95% CI: 662.0-870.5) per 1000 P-Y. After five years of follow-up, the incidence curves plateaued at approximately 4% and 48% for bone metastases and SREs, respectively (Figures 1 and 2). Conclusions Among breast cancer patients with bone metastases, there was a strong tendency towards development of SREs within a year of bone metastases diagnosis; however, this phenomenon stabilized beyond 5 years of bone metastases diagnosis.

Abstract
Point source searches with the IceCube neutrino telescope have been restricted to one hemisphere, due to the exclusive selection of upward going events as a way of rejecting the atmospheric muon background. We show that the region above the horizon can be included by suppressing the background through energy-sensitive cuts. This improves the sensitivity above PeV energies, previously not accessible for declinations of more than a few degrees below the horizon due to the absorption of neutrinos in Earth. We present results based on data collected with 22 strings of IceCube, extending its field of view and energy reach for point source searches. No significant excess above the atmospheric background is observed in a sky scan and in tests of source candidates. Upper limits are reported, which for the first time cover point sources in the southern sky up to EeV energies.

Abstract
ADAM12/meltrin alpha is a type I transmembrane multidomain protein involved in tumor progression and other severe diseases, including osteoarthritis, and as such could be considered as a potential drug target. In addition to protease activity, ADAM12 possesses cell binding and cell signaling properties. This functional trinity is reflected in the structure of ADAM12, which can be divided into head, body, and tail. The head of the protein (consisting of the pro and catalytic domains) mediates processing of growth factors and cytokines and has been implicated in epidermal growth factor (EGF) and insulin-like growth factor receptor signaling. The body of the protein (consisting of the disintegrin, cysteine-rich, and EGF-like domains) is involved in contacts with the extracellular matrix and other cells through interactions with integrins and syndecans. Finally, the tail of the protein (consisting of the cytoplasmic domain) is engaged in interactions with intracellular signaling molecules. In many studies, ADAM12 overexpression has been correlated with disease, and ADAM12 has been shown to promote tumor growth and progression in cancer. On the other hand, protective effects of ADAM12 in disease have also been reported. Future investigations should address the precise mechanisms of ADAM12 in disease and biology in order to counterbalance the benefits from targeting ADAM12 therapeutically with possible side effects. This review describes the biology of ADAM12, its association with disease, and evaluates the possible approaches to targeting ADAM12 in human disease.

Abstract
A search for muon neutrinos from neutralino annihilations in the Sun has been performed with the IceCube 22-string neutrino detector using data collected in 104.3 days of live time in 2007. No excess over the expected atmospheric background has been observed. Upper limits have been obtained on the annihilation rate of captured neutralinos in the Sun and converted to limits on the weakly interacting massive particle (WIMP) proton cross sections for WIMP masses in the range 250-5000 GeV. These results are the most stringent limits to date on neutralino annihilation in the Sun.

Abstract
5160 Background: Common among advanced prostate cancer patients, bone metastases indicate cancer progression and poor prognosis but few studies have quantified their influence on patient survival, particularly in the presence of subsequent skeletal-related complications. We therefore sought to examine this in a large population-based cohort of prostate cancer patients. Methods: Using data from the Danish National Patient Registry (covering all Danish hospitals), we studied 23,087 patients diagnosed with prostate cancer between 1999 and 2007, with follow-up through April 2008 (median follow-up: 2.2 years). We estimated the incidence of bone metastases following cancer diagnosis and the subsequent occurrence of SREs (radiation and surgery to the bone, fracture, spinal cord compression). We then computed and compared survival for three prostate cancer subgroups - no bone metastases, bone metastases, and bone metastases with SREs - using Kaplan-Meier and multivariate Cox proportional hazards models. Results: Across the study period, 14% (n = 3,261) of the prostate cancer patients developed bone metastases: 6.8% (n = 1,570) had bone metastases and no SRE and 7.3% (n = 1,691) had both bone metastases and at least one SRE (radiation to the bone was most frequent). One-year survival was lowest for prostate cancer patients with bone metastases and SREs (40%) compared to the groups with no bone metastases (87%) and with bone metastases but no SREs (47%). Similarly, after adjusting for age and the presence of comorbidities, short-term prognosis was poorest in patients with both bone metastases and SREs: compared to prostate cancer patients with no bone metastases, the 1-year mortality rate was 6.7 times greater for those with bone metastases and SREs (95% confidence interval (CI): 6.0–7.6) versus just 4.7 times higher in those with only bone metastases (95% CI: 4.3–5.2). Less than 1% of prostate cancer patients who developed bone metastases and suffered any SRE survived beyond five years. Conclusions: Although the presence of bone metastases confers a short-term prognosis in prostate cancer patients, survival is even poorer for patients who also experience skeletal-related complications.

Abstract
e20635 Background: Many experts recommend palliative care consultation early in the course of oncology treatment; however little is known about the components of this type of intervention. We sought to better define the components of early palliative care consultation in patients with recently diagnosed incurable cancer. Methods: As part of a larger randomized study of integrated versus standard palliative care in an ambulatory thoracic oncology clinic, we analyzed data from 47 patients who received early palliative care consultation within eight weeks of diagnosis of incurable NSCLC with a performance status of 0–2. Prior to randomization, patients completed questionnaires on quality of life (FACT-L) and mood (HADS) as well as illness understanding. The FACT-L Trial Outcome Index which is a combined score of physical, functional well being, and lung cancer symptoms was calculated and used in correlations to more fully assess quality of life. After the consultation, palliative care clinicians recorded how time was spent during the encounter. Results: Seven palliative care clinicians provided consultation to 47 patients. The mean total time spent with each patient was 59.5 minutes (SD 28.6). The major components of each consultation were symptom management 25.7 minutes (SD 15.8), patient and family coping 19.6 minutes (SD 14.7), and illness understanding and education 10.4 minutes (SD 7.6). Greater total consultation time was correlated with poorer performance status (r=0.30, p=0.04) and lower quality of life scores on the FACT-L TOI which is a combined score of physical, functional wellbeing, and lung cancer symptoms (r=0.36, p=0.01). Symptom management time was also correlated with lower quality of life scores on the FACT-L TOI (r-0.52, p<0.001) and higher depression scores on the HADS (r=0.33, p=0.02). Conclusions: Initial palliative care consultation near the time of diagnosis in patients with incurable NSCLC is lengthy and comprised primarily of symptom management, patient and family coping, and illness understanding and education. Patients with poorer performance status and quality of life received longer total time in consultation and in time devoted to symptom management No significant financial relationships to disclose.

Abstract
The association constants for the binding of bilirubin to human serum albumin (HSA) have been determined at four different temperatures by measurements of the rate of the peroxidase catalyzed oxidation of unbound bilirubin. The change of enthalpy is determined from a van't Hoff plot (ln Kass versus 1/T) to about -13.5 kcal/mol. deltaG degrees is calculated from the binding constants, and deltaS degrees is obtained from: deltaG degrees = deltaH degrees--TdeltaS degrees. The results show that the large negative deltaG degrees (--11 kcal/mol) for binding of bilirubin to HSA is a consequence of the negative deltaH degrees. The entropy was found to be about--8.5 cal/mol/degree and tends to diminish the numerical value of deltaG degrees. The binding constant has also been determined at varying ionic strength. The results show a decrease in binding for increasing salt concentration. The data from the two sets of experiments suggest that hydrogen bonds and salt linkages rather than hydrophobic interactions are the main factor in the binding of bilirubin to its primary site on HSA.

Abstract
The impact of comorbid diseases on ovarian cancer survival is largely unknown. We therefore examined (i) the prevalence of comorbidity among ovarian cancer patients and (ii) the impact of comorbidity on ovarian cancer survival and mortality. Using hospital discharge data, we identified Danish women diagnosed with ovarian cancer between 1995 and 2005 (n= 1995 within a population of 1.6 million) and then computed Charlson comorbidity index scores (0, 1-2, and 3+). We estimated the prevalence of comorbidity and computed absolute survival and relative mortality rate ratios (MRRs) according to comorbidity level, using patients with Charlson score 0 as the reference group. During the study period, the proportion of patients without comorbidity fell from 81% to 75%, while the proportion of patients with comorbidity score 1-2 and 3+ rose from 16% to 21% and from 4% to 5%, respectively. Overall 1-year survival increased from 68% in 1995-1997 to 70% in 1998-2000 and to 73% in 2001-2004. For patients with Charlson score 1-2, 1-year adjusted MRRs were 1.1 (95% CI, 0.8-1.6) in 1995-1997, 1.3 (95% CI, 1.0-1.8) in 1998-2000, and 1.7 (95% CI, 1.3-2.4) in 2001-2004. For patients with Charlson score 3+, 1-year adjusted MRRs were 2.4 (95% CI, 1.4-4.3) in 1995-1997, 1.6 (95% CI, 1.0-2.7) in 1998-2000, and 2.2 (95% CI, 1.3-3.8) in 2001-2004. The 5-year MRRs were similar to the 1-year MRRs. One quarter of Danish women with ovarian cancer were found to have comorbid conditions, and 5% had severe comorbidity. Severe comorbidity was a predictor of poorer survival.

Abstract
Comorbid diseases can affect breast cancer prognosis. We conducted a population-based study of Danish women diagnosed with a first primary breast cancer from 1995 to 2005 (n=9300), using hospital discharge registry data to quantify comorbidities by Charlson score. We examined the influence of comorbidities on survival, and quantified their impact on relative mortality rates. The prevalence of patients with a Charlson score='0' fell from 86 to 81%, with an increase in those with Charlson score='1-2' from 13 to 16%, and score='3+' from 1 to 2%. One- and five-year survival for patients with Charlson score='0' and '1-2' was better for those diagnosed in 1998-2000 than in 1995-1997. Overall, patients diagnosed in 2001-2004 (mortality ratio (MR)=0.80, 95% CI=0.68-0.95) and 1998-2000 (MR=0.92, 95% CI=0.78-1.09) had lower 1-year age-adjusted mortality compared to those diagnosed in 1995-1997 (reference period). Patients with Charlson scores '1-2' and '3+' had higher age-adjusted 1-year mortality than those with a Charlson score='0' in each time period (2001-2004: MR('1-2')=1.76, 95% CI=1.35-2.30, and MR('3+')=3.78, 95% CI=2.51-5.68; and 1998-2000: MR('1-2')=1.60, 95% CI=1.36-1.88 and MR('3+')=2.34, 95% CI=1.65-3.33). Similar findings were observed for 5-year age-adjusted mortality. Additional analyses, adjusted for stage, indicated that confounding by stage could not explain these findings. Despite continued improvements in breast cancer survival, we found a trend of poorer survival among breast cancer patients with severe comorbidities even after adjusting for age and stage. Such poorer survival is an important public health concern and can be expected to worsen as the population ages.

Abstract
OBJECTIVE The prognosis for colorectal cancer (CRC) is less favourable in Denmark than in neighbouring countries. To improve cancer treatment in Denmark, a National Cancer Plan was proposed in 2000. We conducted this population-based study to monitor recent trends in CRC survival and mortality in four Danish counties. METHOD We used hospital discharge registry data for the period January 1985-March 2004 in the counties of north Jutland, Ringkjøbing, Viborg and Aarhus. We computed crude survival and used Cox proportional hazards regression analysis to compare mortality over time, adjusted for age and gender. A total of 19,515 CRC patients were identified and linked with the Central Office of Civil Registration to ascertain survival through January 2005. RESULTS From 1985 to 2004, 1-year and 5-year survival improved both for patients with colon and rectal cancer. From 1995-1999 to 2000-2004, overall 1-year survival of 65% for colon cancer did not improve, and some age groups experienced a decreasing 1-year survival probability. For rectal cancer, overall 1-year survival increased from 71% in 1995-1999 to 74% in 2000-2004. Using 1985-1989 as reference period, 30-day mortality did not decrease after implementation of the National Cancer Plan in 2000, neither for patients with colon nor rectal cancer. However, 1-year mortality for patients with rectal cancer did decline after its implementation. CONCLUSION Survival and mortality from colon and rectal cancer improved before the National Cancer Plan was proposed; after its implementation, however, improvement has been observed for rectal cancer only.

Abstract
On 27 December 2004, a giant gamma flare from the Soft Gamma-Ray Repeater 1806-20 saturated many satellite gamma-ray detectors, being the brightest transient event ever observed in the Galaxy. AMANDA-II was used to search for down-going muons indicative of high-energy gammas and/or neutrinos from this object. The data revealed no significant signal, so upper limits (at 90% C.L.) on the normalization constant were set: 0.05(0.5) TeV-1 m;{-2} s;{-1} for gamma=-1.47 (-2) in the gamma flux and 0.4(6.1) TeV-1 m;{-2} s;{-1} for gamma=-1.47 (-2) in the high-energy neutrino flux.

Abstract
BACKGROUND Case reports have suggested that the use of newer cyclo-oxygenase-2 selective inhibitors may cause acute pancreatitis, but there has been no formal study of the association. AIM To assess the relationship between the use of cyclo-oxygenase-2 inhibitors and other non-steroidal anti-inflammatory drugs, and risk of acute pancreatitis. METHODS A population-based case-control study was conducted using hospital discharge and prescription data from Denmark. Using conditional logistic regression with adjustment for multiple covariates, we estimated the relative risk of acute pancreatitis for use of the cyclo-oxygenase-2 inhibitors celecoxib and rofecoxib and for other non-steroidal anti-inflammatory drugs. RESULTS A total of 3083 cases of acute pancreatitis and 30 830 population controls were identified. For current use the relative risk estimate for celecoxib was 1.4 (95% CI: 0.8-2.3) and for rofecoxib was 1.3 (95% CI: 0.7-2.3). The overall relative risk for other non-steroidal anti-inflammatory drugs was 2.7 (95% CI: 2.4-3.0) with a substantial variation in risk between the individual drugs. The highest relative risk was for diclofenac (odds ratio 5.0, 95% CI: 4.2-5.9) and the lowest for naproxen (odds ratio 1.1, 95% CI: 0.7-1.7). CONCLUSION Cyclo-oxygenase-2 selective inhibitors are associated with a lower risk of acute pancreatitis than most other non-steroidal anti-inflammatory drugs.

Abstract
BACKGROUND Little is known about temporal trends in the incidence and mortality of pneumonia in the general population. METHODS We conducted a population-based cohort study in three Danish counties (population 1.4 million) to examine changes in the incidence and 30- and 90-day mortality associated with hospitalized pneumonia between 1994 and 2004. All adults hospitalized with a first-time diagnosis of pneumonia (n = 41 793) were identified in hospital discharge registries and followed for mortality through the Danish Civil Registry System. We determined age-standardized incidence rates and adjusted mortality rates associated with calendar year, gender, age and comorbidity. RESULTS Between 1994 and 2003, the incidence of hospitalized pneumonia amongst adults increased from 288 per 100 000 person-years to 442 per 100 000 person-years, equivalent to an age-standardized incidence rate ratio of 1.50. The cumulative mortality within 30 and 90 days of admission was 15.2% and 21.9%, respectively, ranging from a 90-day mortality of 2.5% in patients aged 15-39 years to 34.7% in those aged 80 and over. Advanced age was the most important poor prognostic factor, followed by a high comorbidity score and male gender. The adjusted mortality rate ratios amongst patients with hospitalized pneumonia in 1999-2004, when compared with 1994-1998, were 0.89 (95% CI 0.85-0.94) after 30 days and 0.91 (95% CI 0.88-0.95) after 90 days. CONCLUSIONS The incidence of hospitalized pneumonia in Denmark has increased considerably during the last 10 years and, combined with persistently high mortality rates, is of clinical and public health concern.

Abstract
BACKGROUND Case reports have suggested that statins may cause acute pancreatitis. AIM To examine if statins are associated with risk of acute pancreatitis. METHODS We identified 2576 first-time admitted cases of acute pancreatitis from hospital discharge registers in three Danish counties, and 25 817 age- and gender-matched controls from the general population. Prescriptions for statins prior to admission with acute pancreatitis or index date among controls were retrieved from prescription databases. We used conditional logistic regression analysis to estimate odds ratios for acute pancreatitis among ever (ever before), current (0-90 days before), new (first prescription in 0-90 days before) and former (>90 days, but not 0-90 days before) users of statins. RESULTS Adjusted odds ratios for acute pancreatitis among ever, current, new and former users of statins were 1.44 (95% confidence interval: 1.115-1.80), 1.26 (95% confidence interval: 0.96-1.64), 1.01 (95% confidence interval: 0.43-2.37) and 2.02 (95% confidence interval: 1.37-2.97), respectively. There was an indication of an inverse association between the number of filled prescriptions and risk of acute pancreatitis. CONCLUSIONS Our findings speak against a strong causative effect of statins on the risk of acute pancreatitis, and may even indicate a mild protective effect.

Abstract
OBJECTIVE Ovarian cancer is a serious disease with a high mortality. Our aim was to examine changes in the survival of patients with ovarian cancer in Northern Denmark. STUDY DESIGN AND SETTING Patients (no. = 3,719) with an incident discharge diagnosis of ovarian cancer (1985-2004) from any hospital in four Danish counties (population, 1.6 million) were included and tracked for mortality through the Danish Civil Registration System. We determined survival and mortality rates stratified by age, and used Cox proportional hazard regression analyses to assess changes over time. RESULTS Overall survival rate improved between 1985 and 2004. One-year survival increased from 61% to 73%, and five-year survival from 30% to 38%. Compared with the period 1985-1989 the age-adjusted one-year mortality rate ratio (MRR) was 0.65 (2000-2004) and the age-adjusted five-year MRR was 0.80 (1995-1999). The improvement was most pronounced in patients older than 40 years. CONCLUSION The survival of ovarian cancer patients has improved in Denmark in recent decades. This change may be the result of improved treatment.

Abstract
BACKGROUND Use of metronidazole has been suggested to be associated with an increased risk of acute pancreatitis in case reports. AIM To examine this issue within a proper epidemiological design. METHODS We identified 3083 incident cases of acute pancreatitis from Hospital Discharge Registries in three Danish counties and 30 830 matched population controls. From prescription databases, we extracted information on use of metronidazole with or without concomitant use of proton-pump inhibitors and/or amoxicillin, macrolides or tetracycline. RESULTS Adjusted odds ratios for acute pancreatitis in study subjects who redeemed a prescription for metronidazole within 30, 31-180, or 181-365 days before hospitalization or index date among controls were 3.0 [95% confidence interval (CI): 1.4-6.6], 1.8 (95% CI: 1.2-2.9) and 1.1 (95% CI: 0.6-1.8), respectively. Among subjects with a concomitant prescription for proton-pump inhibitors and/or amoxicillin, macrolides or tetracycline within 30, 31-180, or 181-365 days before hospitalization, or index date among controls, adjusted odds ratios were 8.3 (95% CI: 2.6-26.4), 2.7 (95% CI: 1.4-5.5), and 1.7 (95% CI: 0.6-4.8), respectively. CONCLUSION Metronidazole may increase the risk of acute pancreatitis. However, the risk seems mainly to increase when metronidazole is used in combination with other drugs used for Helicobacter pylori eradication.

Abstract
BACKGROUND Immunosuppressive therapy with azathioprine and mercaptopurine is commonly used in patients with various chronic diseases. The few existing data on the reproductive safety of these drugs after paternal use before conception are inconclusive. AIM To examine the risk of congenital abnormalities in children fathered by men exposed to azathioprine or mercaptopurine before conception. METHODS This was a Danish population-based cohort study, based on data from the Prescription Database, the Medical Birth Registry and the Hospital Discharge Registry of North Jutland County, Denmark. Fifty-four exposed pregnancies, in which the father filed a prescription for azathioprine or mercaptopurine (between 1 January 1991 and 31 December 2001) before conception, were included. The controls comprised 57 195 pregnancies with no paternal azathioprine or mercaptopurine use. RESULTS Four children with congenital abnormalities (underlying paternal diseases: glomerulonephritis and severe skin disease) were found in 54 exposed pregnancies (7.4%), compared with 2334 (4.1%) in controls. The adjusted odds ratio for congenital abnormalities in children fathered by men treated with azathioprine or mercaptopurine was 1.8 (95% confidence interval, 0.7-5.0). CONCLUSIONS Our data may indicate that paternal use of azathioprine or mercaptopurine before conception is associated with an increased risk of congenital abnormalities. However, more data are needed to determine whether the association is causal.

Abstract
We present the results of a search for point sources of high-energy neutrinos in the northern hemisphere using AMANDA-II data collected in the year 2000. Included are flux limits on several active-galactic-nuclei blazars, microquasars, magnetars, and other candidate neutrino sources. A search for excesses above a random background of cosmic-ray-induced atmospheric neutrinos and misreconstructed downgoing cosmic-ray muons reveals no statistically significant neutrino point sources. We show that AMANDA-II has achieved the sensitivity required to probe known TeV gamma-ray sources such as the blazar Markarian 501 in its 1997 flaring state at a level where neutrino and gamma-ray fluxes are equal.
