SICStus Prolog library manual, version 2.1 #8
- 1993. - 1

Rapport (övrigt vetenskapligt/konstnärligt)abstract
- This Manual corresponds to SICStus Prolog release 2.1. #8 The Prolog library comprises a number of packages which are thought to be useful in a number of applications. Note that the predicates in the Prolog library are built-in predicates. One has to explicity load each package to get access to its predicates. To load a library package Package, you will normally enter a query. I ?- use_module(library(Package)). Library packages may be compiled and consulted as well as loaded.

- During the past few years cryotransmission electron microscopy (EM) of vitrified thin samples has gained acceptance as a standard method in the arsenal of the colloid and interface scientist. The seemingly direct visualization of fluid colloidal structures during the use of cryotransmission EM is both convincing and reliable to the scientist who nowadays has an increasing awareness of the limitations and pitfalls of instrumentation. Notable recent observations include branched threadlike micelles, faceted particles (cubosomes) of a dispersed cubic phase and transitions of certain structures from globular micelles via bilayers to reversed structures. These transitions may be caused by changes of compos ition, temperature, pH, or salt concentration.

- BACKGROUND: Tumor development requires angiogenesis, and antiangiogenesis has been introduced in the treatment of cancer patients; however, how the cardiovascular phenotype correlates with cancer risk remains ill-defined. Here, we hypothesized that vasoactive peptides previously implicated in angiogenesis regulation predict long-term cancer risk.METHODS: We measured midregional proatrial natriuretic peptide (MR-proANP), proadrenomedullin (MR-proADM), and C-terminal preprovasopressin (copeptin) in fasting plasma from participants of the Malmö Diet and Cancer Study that were free from cancer prior to the baseline exam in 1991 to 1994 (1,768 males and 2,293 females). We used Cox proportional hazards models to determine the time to first cancer event in relation to baseline levels of vasoactive peptides during a median follow-up of 15 years.RESULTS: First cancer events occurred in 366 males and in 368 females. In males, one SD increase of MR-proANP, copeptin, and MR-proADM was independently related to incident cancer [HR (95% CI)] by 0.85 (0.74-0.96), P = 0.012; 1.17 (1.04-1.32), P = 0.009; and 1.12 (0.99-1.26), P = 0.065, respectively, and a summed biomarker score identified an almost 2-fold difference in cancer risk between the top and bottom quartile (P < 0.001). In younger males, the biomarker score identified a more than 3-fold increase in risk between the top and bottom quartile (P < 0.001). Among females, we found no relationship between biomarkers and cancer incidence.CONCLUSIONS: Our data suggest that vasoactive peptide biomarkers predict cancer risk in males, particularly in younger males.Impact: Our findings may have implications for cancer risk prediction and present novel, potentially drug modifiable, mechanisms underlying cancer development.

- BACKGROUND: This paper investigates the impact of a non-mandatory and age-specific social distancing recommendation on isolation behaviors and disease outcomes in Sweden during the first wave of the COVID-19 pandemic (March to July, 2020). The policy stated that people aged 70 years or older should avoid crowded places and contact with people outside the household.METHODS: We used a regression discontinuity design-in combination with self-reported isolation data from COVID Symptom Study Sweden (n = 96,053; age range: 39-79 years) and national register data (age range: 39-100+ years) on severe COVID-19 disease (hospitalization or death, n = 21,804) and confirmed cases (n = 48,984)-to estimate the effects of the policy.RESULTS: Our primary analyses showed a sharp drop in the weekly number of visits to crowded places (-13%) and severe COVID-19 cases (-16%) at the 70-year-threshold. These results imply that the age-specific recommendations prevented approximately 1,800 to 2,700 severe COVID-19 cases, depending on model specification.CONCLUSION: It seems that the non-mandatory, age-specific recommendations helped control COVID-19 disease during the first wave of the pandemic in Sweden, as opposed to not implementing a social distancing policy aimed at older adults. Our study provides empirical data on how populations may react to non-mandatory, age-specific social distancing policies in the face of a novel virus.SUPPLEMENTARY MATERIAL: Online appendix with figures, tables, extra methods and results.

- The epidemiological evidence for an obesity-cancer association is solid, whereas the association between obesity-associated lipoprotein levels and cancer is less evident. We investigated circulating levels of Apolipoprotein A1 (ApoA1), Apolipoprotein B (ApoB), LDL-cholesterol (LDL-C) and HDL-cholesterol (HDL-C) and association to risk of overall cancer and common cancer forms. The Malmö Diet and Cancer Study, a population-based prospective cohort study, enrolled 17,035 women and 11,063 men (1991-1996). Incident cancer cases were ascertained by record linkage with the Swedish Cancer Registry until end of follow-up, Jan 1(st) 2012. Baseline serum levels of ApoA1 and ApoB were analyzed for the entire cohort, and HDL-C and LDL-C levels in 5,281 participants. Hazard ratios, with 95% confidence interval, were calculated using Cox's proportional hazards analysis. In the entire cohort, none of the exposures were related to overall cancer risk (HRadj ApoA1=0.98, 95%CI: 0.95,1.01; HRadj ApoB=1.01, 95%CI: 0.98-1.04). Among men, ApoB was positively associated with cancer risk (HRadj ApoB=1.06, 95%CI: 1.01,1.10). Female breast cancer risk was inversely associated with ApoB (HRadj =0.92, 95%CI: 0.86,0.99). Among both genders, ApoA1 was inversely associated with lung cancer risk (HRadj =0.88, 95%CI: 0.80,0.97), whereas high ApoB increased lung cancer risk (HRadj =1.08, 95%CI: 0.99,1.18). Colorectal cancer risk was increased with high ApoB (HRadj =1.08, 95%CI: 1.01,1.16) among both genders. Apolipoprotein levels were not associated with prostate cancer incidence. Circulating levels of apolipoproteins are associated with overall cancer risk in men and across both genders with breast, lung, and colorectal cancer risk. Validation of these findings may facilitate future primary prevention strategies for cancer. This article is protected by copyright. All rights reserved.

Tidskriftsartikel (refereegranskat)abstract
- Previous studies have suggested that thyroid function is associated with breast cancer risk, which could have an important clinical impact, as one in eight women will develop a thyroid disorder during her lifetime. However, the underlying pathomechanism behind the association is still unknown. We used the Malmö Diet and Cancer Study (a population-based prospective study consisting of 17,035 women) to examine 17 single nucleotide polymorphisms (SNPs) previously related to levels of free thyroxine (free T4) and thyroid peroxidase antibodies (TPO-Ab) as potential genetic risk factors for breast cancer. A baseline examination including free T4 and TPO-Ab levels was conducted at the time of inclusion. Genotyping was performed on 901 breast cancer patients and 3335 controls. Odds ratios (95% confidence intervals) for high free T4, TPO-Ab positivity, and breast cancer were calculated by logistic regression and adjusted for confounders. We identified one free T4-related SNP (rs2235544, D101 gene) that was significantly associated with both free T4 level and breast cancer risk. There was a suggested association between rs11675434 (TPO gene) and TPO-Ab level, and TPO-Ab-related rs11675434 (TPO), rs3094228 (HCP5), rs1033662 (no registered gene), and rs301806 (RERE) were associated with breast cancer risk. There was an indicated interaction between rs6485050 (no registered gene) and free T4 level in regards to breast cancer risk. This is the first study to suggest an association between thyroid-related SNPs and breast cancer risk. All SNPs have a biological plausibility of being associated with breast cancer risk, and may contribute to the genetic predisposition to breast cancer.
