- BackgroundIt has been suggested that coeliac disease (CD) is associated with several neurological diseases. However, the evidence of such an association is inconclusive as earlier research has often been based on small numbers with retrospective data collection.AimTo use Cox regression to examine the risk of neurological disease in individuals with CD.MethodsThrough Swedish national registers we identified some 14 000 individuals with a diagnosis of CD (1964–2003) and 70 000 reference individuals matched for age, sex, calendar year and county.ResultsCoeliac disease was associated with later polyneuropathy [hazard ratio (HR) = 3.4; 95% CI = 2.3–5.1]. We found no statistically significant association between CD and subsequent multiple sclerosis (HR = 0.9; 95% CI = 0.3–2.3), Parkinson’s disease (HR = 1.2; 95% CI = 0.8–1.9), Alzheimer’s disease (HR = 1.5; 95% CI = 0.9–2.6), hereditary ataxia (HR = 1.3; 95% CI = 0.5–3.6), the symptom ataxia (HR = 1.9; 95% CI = 0.6–6.2), Huntington’s disease (HR = 1.7; 95% CI = 0.3–8.6), myasthenia gravis (HR = 0.8; 95% CI = 0.2–3.8) or spinal muscular atrophy (HR = 0.5; 95% CI = 0.1–3.8). Prior polyneuropathy was associated with subsequent CD (odds ratio = 5.4; 95% CI = 3.6–8.2).ConclusionsThe association between CD and polyneuropathy indicates shared risks. We suggest that individuals with polyneuropathy routinely undergo screening for CD. There is no notable association between CD and other neurological outcomes investigated in this study.

Tidskriftsartikel (refereegranskat)abstract
- The aim of this study was to analyse willingness to pay (WTP) and ability to pay (ATP) for ACT for children below five years of age in a rural setting in Tanzania before the introduction of artemisinin-based combination therapy (ACT) as first-line treatment for uncomplicated malaria. Socio-economic factors associated with WTP and expectations on anti-malaria drugs, including ACT, were also explored.MethodsStructured interviews and focus group discussions were held with mothers, household heads, health-care workers and village leaders in Ishozi, Gera and Ishunju wards in north-west Tanzania in 2004. Contingent valuation method (CVM) was used with "take-it-or-leave-it" as the eliciting method, expressed as WTP for a full course of ACT for a child and households' opportunity cost of ACT was used to assess ATP. The study included descriptive analyses with multivariate adjustment for potential confounding factors.ResultsAmong 265 mothers and household heads, 244 (92%, CI = 88%–95%) were willing to pay Tanzanian Shillings (TSh) 500 (US$ 0.46) for a child's dose of ACT, but only 55% (49%–61%) were willing to pay more than TSh 500. Mothers were more often willing to pay than male household heads (adjusted odds ratio = 2.1, CI = 1.2–3.6). Socio-economic status had no significant effect on WTP. The median annual non-subsidized ACT cost for clinical malaria episodes in an average household was calculated as US$ 6.0, which would represent 0.9% of the average total consumption expenditures as estimated from official data in 2001. The cost of non-subsidized ACT represented 7.0% of reported total annual expenditure on food and 33.0% of total annual expenditure on health care."Rapid effect," "no adverse effect" and "inexpensive" were the most desired features of an anti-malarial drug.ConclusionWTP for ACT in this study was less than its real cost and a subsidy is, therefore, needed to enable its equitable affordability. The decision taken in Tanzania to subsidize Coartem® fully at governmental health care facilities and at a consumer price of TSh 300–500 (US$ 0.28–0.46) at special designated shops through the programme of Accredited Drug Dispensing Outlets (ADDOs) appears to be well founded.

- Background: Earlier studies have suggested that untreated coeliac disease may be associated with osteoporosis, but results are contradictory for the risk of long-term fractures.Aim: To study the association between coeliac disease and fractures.Methods: We used Cox regresson to examine the future risk of hip fracture and fracture of any type in more than 13 000 individuals with coeliac disease and 65 000 age- and sex-matched reference individuals in a general population-based cohort.Results: During follow-up, 1365 first hip fractures and 4847 fractures of any type occurred. Coeliac disease was positively associated with subsequent hip fracture (hazard ratio = 2.1; 95% CI = 1.8-2.4) (in children: hazard ratio = 2.6; 95% CI = 1.1-6.2) and fractures of any type (hazard ratio = 1.4; 95% CI = 1.3-1.5) (in children: hazard ratio = 1.1; 95% CI = 1.0-1.2). The absolute excess risk of hip fractures in children with coeliac disease was 4/100 000 person-years. Incidence ratios for hip fracture in individuals with CD were around two both prior to diagnosis of coeliac disease and afterwards; this risk increase remained 20 years after diagnosis of coeliac disease.Conclusions: Individuals with coeliac disease, including children with coeliac disease, may be at increased risk of hip fracture and fracture of any type. Coeliac disease may be positively associated with long-term hip fracture risk.

- Metabolism of androgens includes glucuronidation, the major pathway of steroid elimination in several steroid target tissues. Glucuronidation is catalysed by UDP-glucuronosyltransferases (UGTs). UGT2B17 has been shown to be particularly active against androgens and is highly abundant in the prostate. Recently, we discovered that deletion of the UGT2B17 gene is associated with low or undetectable urinary testosterone levels. Here, we determined the phenotypic outcome of the deletion by quantifying the UGT2B17 mRNA expression in normal prostate tissues in individuals with different genotypes. Additionally, the frequency of UGT2B17 deletion polymorphism was studied in a Swedish population-based case–control study including 176 patients diagnosed with prostate cancer and 161 controls. We found that the individuals homozygous for the insertion allele expressed 30 times more UGT2B17 mRNA in prostate tissue than the heterozygotes. Carriers of the deletion allele had a significantly increased risk of prostate cancer (OR=2.07; 95% CI=1.32–3.25). In conclusion, these results show the UGT2B17 deletion polymorphism is associated with prostate cancer risk.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: The inappropriate use of anabolic androgenic steroids (AAS) was originally a problem among athletes but AAS are now often used in nonsport situations and by patients attending regular addiction clinics. The aim of this study was to improve understanding of the development of multiple drug use in patients seeking treatment at an addiction clinic for AAS-related problems. METHODS: We interviewed six patients (four men and two women) with experience of AAS use who were attending an addiction clinic for what they believed were AAS-related problems. The patients were interviewed in-depth about their life stories, with special emphasis on social background, substance use, the development of total drug use and subjective experienced psychological and physical side effects. RESULTS: There was significant variation in the development of drug use in relation to social background, onset of drug use, relationship to AAS use and experience of AAS effects. All patients had initially experienced positive effects from AAS but, over time, the negative experiences had outweighed the positive effects. All patients were dedicated to excess training and took AAS in combination with gym training, indicating that the use of these drugs is closely related to this form of training. Use of multiple drugs was common either in parallel with AAS use or serially. CONCLUSIONS: The study shows the importance of understanding how AAS use can develop either with or without the concomitant use of other drugs of abuse. The use of AAS can, however, progress to the use of other drugs. The study also indicates the importance of obtaining accurate, comprehensive information about the development of AAS use in designing treatment programmes and prevention strategies in this area.

CPSign : Conformal Prediction for Cheminformatics Modeling
- 2024
-
Ingår i: Journal of Cheminformatics. - : BioMed Central (BMC). - 1758-2946. ; 16
-
Tidskriftsartikel (refereegranskat)abstract
- Conformal prediction has seen many applications in pharmaceutical science, being able to calibrate outputs of machine learning models and producing valid prediction intervals. We here present the open source software CPSign that is a complete implementation of conformal prediction for cheminformatics modeling. CPSign implements inductive and transductive conformal prediction for classification and regression, and probabilistic prediction with the Venn-ABERS methodology. The main chemical representation is signatures but other types of descriptors are also supported. The main modeling methodology is support vector machines (SVMs), but additional modeling methods are supported via an extension mechanism, e.g. DeepLearning4J models. We also describe features for visualizing results from conformal models including calibration and efficiency plots, as well as features to publish predictive models as REST services. We compare CPSign against other common cheminformatics modeling approaches including random forest, and a directed message-passing neural network. The results show that CPSign produces robust predictive performance with comparative predictive efficiency, with superior runtime and lower hardware requirements compared to neural network based models. CPSign has been used in several studies and is in production-use in multiple organizations. The ability to work directly with chemical input files, perform descriptor calculation and modeling with SVM in the conformal prediction framework, with a single software package having a low footprint and fast execution time makes CPSign a convenient and yet flexible package for training, deploying, and predicting on chemical data. CPSign can be downloaded from GitHub at https://github.com/arosbio/cpsign.

- The aim of this study was to investigate the relevance of mouse ex vivo cultures as a first screening model for new therapeutic agents of Inflammatory Bowel Disease (IBD). Two murine models (dextran sodium sulphate (DSS)-induced colitis and Gαi2-deficient mice) and two anti-inflammatory agents (methyl-prednisolone and the proteasome inhibitor MG132) were evaluated. The in vivo effects of methyl-prednisolone were assessed in both models. Ex vivo colonic tissue from both mouse models were cultured in the presence or absence of the drugs and TaqMan Low-Density arrays were used to assess the regulation of inflammatory genes before and after drug treatment. Colitis induced a similar inflammatory gene profile in both mouse models in in vivo studies and in ex vivo cultures. The differences encountered reflected the different phases of colitis in the models, e.g. innate cytokine/chemokine profile in the DSS model and T cell related markers in Gαi2-deficient mice. After steroid treatment, a similar pattern of genes was suppressed in the two mouse models. We confirmed the suppression of inflammatory gene expression for IL-1β, IL-6 and iNOS in ex vivo and in vivo colons from both mouse models by quantitative RT-PCR. Importantly, the inflammatory responses in the murine ex vivo culture system reflected the in vivo response in the inflamed colonic tissue as assessed by changes in inflammatory gene expression, suggesting that the murine culture system can be used for validation of future IBD therapies.

- Skin serves as a drug administration route, and skin permeability of chemicals is of significant interest in the pharmaceutical and cosmetic industries. An aggregated conformal prediction (ACP) framework was used to build models, for predicting the permeation rate (log K-p) of chemical compounds through human skin. The conformal prediction method gives as an output the prediction range at a given level of confidence for each compound, which enables the user to make a more informed decision when, for example, suggesting the next compound to prepare, Predictive models were built using;both the random forest and the support vector machine methods and were based on experimentally derived permeability data on 211 diverse compounds. The derived models were of similar predictive quality as compared to earlier published models but have the extra advantage of not only presenting a single predicted value for each, compound but also a reliable, individually assigned prediction range. The models use calculated descriptors and can quickly predict the skin permeation rate of new compounds.
