Low breast cancer screening rates are often found among ethnic minority groups and those born outside the host country. This is of particular concern for high-risk groups, who should benefit from ongoing trials aimed at optimizing screening strategies for breast, as well as ovarian cancer. Both of these issues are germane for Jewish women in Europe. We systematically review the literature concerning breast cancer early detection practices (BCEDP) among Jewish women, and examine European surveillance studies of high-risk for breast and/or ovarian cancer that had imaging in the surveillance protocol, in order to assess the likelihood of adequately including women from minority ethnic groups. No studies were found about BCEDP among Jewish women in Europe. Twenty-one research groups from Israel or the US addressed BCEDP among Jewish women. Some Jewish women in the US and Israel, including recent immigrants, are under-screened. Twenty-four research groups reported imaging surveillance of women at increased risk for breast and/or ovarian cancer in Europe. There was a clear benefit to magnetic resonance imaging and/or more intensive screening for women with increased breast cancer risk. Some of these surveillance studies considered ethnic minority groups at high risk, including Jewish women, but none provided adequate outreach to ensure that these groups were included in their programs. The specific screening needs of Jewish and other high-risk ethnic minority groups in Europe have not been met regarding breast and ovarian cancer. A European-wide, population-based approach is suggested, with cultural sensitivity being vital for these efforts. © 2010 Springer-Verlag.

Swedish laboratories reported an increase of Mycoplasma pneumoniae during the autumn 2011. Data from the laboratory in Skövde, covering 12.9% of the Swedish population, indicate an approximate increase in the number of laboratory-confirmed cases in the whole country, from around 3,500 in 2009 to 11,100 in 2011. Antibiotics are recommended only for pneumonia, not bronchitis, but compared with the autumn 2009, 42,652 more prescriptions of doxycycline and macrolides were registered in the autumn 2011.

Introduction: Mammographic density (MD) is a strong, independent risk factor for breast cancer, but measuring MD is time consuming and reader dependent. Objective MD measurement in a high-throughput fashion would enable its wider use as a biomarker for breast cancer. We use a public domain image-processing software for the fully automated analysis of MD and penalized regression to construct a measure that mimics a well-established semiautomated measure (Cumulus). We also describe measures that incorporate additional features of mammographic images for improving the risk associations of MD and breast cancer risk.Methods: We randomly partitioned our dataset into a training set for model building (733 cases, 748 controls) and a test set for model assessment (765 cases, 747 controls). The Pearson product-moment correlation coefficient (r) was used to compare the MD measurements by Cumulus and our automated measure, which mimics Cumulus. The likelihood ratio test was used to validate the performance of logistic regression models for breast cancer risk, which included our measure capturing additional information in mammographic images.Results: We observed a high correlation between the Cumulus measure and our measure mimicking Cumulus (r = 0.884; 95% CI, 0.872 to 0.894) in an external test set. Adding a variable, which includes extra information to percentage density, significantly improved the fit of the logistic regression model of breast cancer risk (P = 0.0002).Conclusions: Our results demonstrate the potential to facilitate the integration of mammographic density measurements into large-scale research studies and subsequently into clinical practice. © 2012 Li et al.; licensee BioMed Central Ltd.

In this work we evaluate an approach for breast density assessment of digital breast tomosynthesis (DBT) data using the central projection image. A total of 348 random cases (both FFDM CC and MLO views and DBT MLO views) were collected using a Siemens Mammomat Inspiration tomosynthesis unit at Unilabs, Malmö. The cases underwent both BI-RADS 5th Edition labeling by radiologists and automated volumetric breast density analysis (VBDA) by an algorithm. Preliminary results showed an observed agreement of 70% (weighted Kappa, κ = 0.73) between radiologists and VBDA using FFDM images and 63% (κ = 0.62) for radiologists and VBDA using DBT images. Comparison between densities for FFDM and DBT resulted in high correlation (r = 0.94) and an observed agreement of 72% (κ = 0.76). The automated analysis is a promising approach using low dose central projection DBT images in order to get radiologist- like density ratings similar to results obtained from FFDM. © Springer International Publishing Switzerland 2016.

Background: Recurrent Clostridium difficile infection (CDI) is a significant problem due to its increased incidence and severity. Failure rates for standard antibiotic therapies are high. In our hospital, faecal microbiota transplantation (FMT), or instillation of a culture mixture of known enteric bacteria in saline as rectal bacteriotherapy (RBT), has long been used as 'rescue therapy' in patients with recurrent disease, in whom repeated courses of standard antibiotic treatment have failed. We wanted to evaluate the effectiveness of FMT and RBT for recurrent CDI. Methods: The records of 31 patients treated with either FMT or RBT for recurrent CDI were reviewed retrospectively. FMT was based on faecal donation by a close relative and RBT on a defined saline mixture of 10 individually cultured enteric bacterial strains originally isolated from healthy persons. Both types of instillation were carried out through a rectal catheter. FMT (500 ml) was given as 1 installation. RBT (200 ml) was given as 2 or 3 installations with an interval of 2 days between courses. Treatment success was defined as a sustained loss of symptoms and discontinuation of diarrhoea within 3 days. Results: Of 31 patients, 23 (74%) responded successfully to the treatment: 16 of 23 (70%) receiving FMT and 7 of 8 (88%) receiving RBT. Conclusion: We found FMT to be effective in patients with recurrent CDI. RBT based on a predefined bacterial suspension was as effective as or better than FMT based on faecal donation; however, multiple installations may be needed. © 2014 Informa Healthcare.
