- BACKGROUND: Sexual health and sexual activity are important elements of an individual's well-being. For couples, this topic is often affected after a myocardial infarction (MI). It has become increasingly clear that, after an MI, patients are insufficiently educated on how to resume normal sexual activity. However, sufficient data on the general knowledge that patients and partners have about sexual activity and MI are lacking.OBJECTIVE: The aims of this study were to explore and compare patients' and partners' sexual knowledge 1 month after a first MI and 1 year after the event and to compare whether the individual knowledge had changed over time. A second aim was to investigate whether patients and their partners report receiving information about sexual health and sexual activity from healthcare professionals during the first year after the event and how this information was perceived.SUBJECTS AND METHODS: This descriptive, comparative survey study enrolled participants from 13 Swedish hospitals in 2007-2009. A total of 115 patients with a first MI and their partners answered the Sex After MI Knowledge Test questionnaire 1 month after the MI and 1 year after the event. Correct responses generated a maximum score of 75.RESULTS: Only 41% of patients and 31% of partners stated that they had received information on sex and relationships at the 1 year follow-up. The patients scored 51 ± 10 on the Sex After MI Knowledge Test at inclusion into the study, compared with the 52 ± 10 score for the partners. At the 1-year follow-up, the patients' knowledge had significantly increased to a score of 55 ± 7, but the partners' knowledge did not significantly change (53 ± 10).CONCLUSIONS: First MI patients and their partners reported receiving limited information about sexual issues during the cardiac rehabilitation and had limited knowledge about sexual health and sexual activity.

- Background: As part of preparation for a Swedish multicentre study, exploring sexual and married life in patients with myocardial infarction and their partners, a Swedish validated instrument was required. Aims:The aim of this pilot study was to evaluate the validity and reliability of a Swedish version of the Watts Sexual Function Questionnaire (WSFQ) among persons with a heart disease.Methods:A convenience sample of 79 persons (47 men and 32 women) living with a heart disease was recruited from the members of the National Association of Heart and Lung Patients. They completed a Swedish version of the WSFQ on two occasions. Results:Two separate factor analyses each revealed a two-factor structure on both occasions: “Sexual appetite” and “Sexual expectations ”with gender-neutral questions and “Sexual sensitiveness” and “Sexual ability” with gender-specific questions. Cronbach's alpha coefficients ranged from 0.48 to 0.86 and test – retest values for all but one question exceeded 0.70.Conclusions:The Swedish version of the WSFQ showed good validity and stability and acceptable internal homogeneity. Extended evaluations of the questionnaire are recommended.

How to find simple and accurate rules for viral protease cleavage specificities

- BACKGROUND:Proteases of human pathogens are becoming increasingly important drug targets, hence it is necessary to understand their substrate specificity and to interpret this knowledge in practically useful ways. New methods are being developed that produce large amounts of cleavage information for individual proteases and some have been applied to extract cleavage rules from data. However, the hitherto proposed methods for extracting rules have been neither easy to understand nor very accurate. To be practically useful, cleavage rules should be accurate, compact, and expressed in an easily understandable way.RESULTS:A new method is presented for producing cleavage rules for viral proteases with seemingly complex cleavage profiles. The method is based on orthogonal search-based rule extraction (OSRE) combined with spectral clustering. It is demonstrated on substrate data sets for human immunodeficiency virus type 1 (HIV-1) protease and hepatitis C (HCV) NS3/4A protease, showing excellent prediction performance for both HIV-1 cleavage and HCV NS3/4A cleavage, agreeing with observed HCV genotype differences. New cleavage rules (consensus sequences) are suggested for HIV-1 and HCV NS3/4A cleavages. The practical usability of the method is also demonstrated by using it to predict the location of an internal cleavage site in the HCV NS3 protease and to correct the location of a previously reported internal cleavage site in the HCV NS3 protease. The method is fast to converge and yields accurate rules, on par with previous results for HIV-1 protease and better than previous state-of-the-art for HCV NS3/4A protease. Moreover, the rules are fewer and simpler than previously obtained with rule extraction methods.CONCLUSION: A rule extraction methodology by searching for multivariate low-order predicates yields results that significantly outperform existing rule bases on out-of-sample data, but are more transparent to expert users. The approach yields rules that are easy to use and useful for interpreting experimental data.

- Objective: The objective of this paper is to investigate health-related quality of life (HRQoL), fatigue, anxiety and depression in patients with systemic lupus erythematosus (SLE) and higher levels of pain and to compare them to patients with lower levels of pain and controls.Method: Patients were dichotomized into two groups based on SLE-related pain score on the visual analog scale (VAS): low-pain group (76%, n=64, VAS 0-39 mm) and high-pain group (24%, n=20, VAS 40-100 mm). Sex- and age-matched controls were randomly selected from the general population. Participants were asked to complete questionnaires regarding self-reported pain, HRQoL, fatigue, anxiety and depression. Medical assessments also were recorded.Result: Fatigue score in the high-pain group (median, 36.5; interquartile range (IQR), 32.5-39.7) was significantly higher (p<0.001) compared to the low-pain group (median, 23; IQR, 14.6-34.1), as well as scores for anxiety (median, 9; IQR, 6.5-11.5) and depression (median, 7.5; IQR, 5.5-9) (p<0.001). The high-pain group had significantly lower scores compared to the low-pain group in all dimensions in the SF-36 (p ≤ 0.001-0.007). No statistical differences were detected between the low-pain group and controls in any measurement except for the dimensions physical function, general health, vitality and social function in SF-36. Conclusion Patients with SLE scoring higher degrees of pain were burdened with more fatigue, anxiety and depression and lower levels of HRQoL compared to patients with lower levels of pain who did not differ significantly from the general population in most dimensions. These results elucidate the importance of identifying patients with higher degrees of pain who are probably in need of more extensive multidimensional interventions to decrease symptom burden.
