Wooden Breast

Wooden breast (WB) abnormality adversely impacts the quality of chicken meat and has been linked with oxidative stress. In this study, breast samples were taken from carcasses of 7-week-old Ross 308 broilers 20-min and 24-h postmortem. Five WB and seven non-WB control samples were assigned based on palpatory hardness (non-WB = no unusual characteristics and WB = focal or diffused hardness). WB exhibited lower contents of protein and the amino acids, i.e., isoleucine, leucine and valine, lighter surface color, lower shear force, greater drip loss and altered mineral profiles (p ≤ 0.05). Despite no difference in lipid oxidation, a greater degree of protein oxidation was found in the WB meat (p ≤ 0.05). Absolute transcript abundances of superoxide dismutase, hypoxia inducible factor 1 alpha and pyruvate dehydrogenase kinase 1 were greater in WB (p ≤ 0.05), whereas lactate dehydrogenase A expression was lower in WB (p ≤ 0.05). The findings support an association between oxidative stress and the altered nutritional and technological properties of chicken meat in WB.

1552 Background: The major techniques used to diagnose breast abnormality has been for many years fine-needle aspiration (FNA) cytology and core needle biopsy (CNB) and more recently vacuum-assisted core biopsy (VACB). These techniques are accurate and allow definitive therapeutic surgery. The aim of our study was to detemine whether cytology/histologic findings mach histologic findings at excision. Methods: In our Institution, between January 2004 and June 2006, 43,138 mammographic exams were performed. 1,012 patients had patological lesions at mammography: 617 FNA cytology ( C due to European guidelines for breast cancer screening assessment) and 395 CNB/VACB (B) were performed. Patients with respectively suspicious and malignant FNA cytology (C4 and C5) and respectively uncertain malignant potential, suspicious and malignant histology (B3, B4 and B5) underwent to surgery. Results: The number of cancer identified by FNA cytology was 158 and the number of cancer identified by CNB/VACB was 253. The correlation of preoparative citology/histology with definitive histology had showed: false negative rate respectively 0.79% for histology (B) and 3.16% for cytology (C). False positive rate was respectively 0.4% for B and 0.63 for C. Complete sensitivity was 98.2% for B and 89.87% for C. Absolute sensitivity was 90.51% for B and 76.58% for C. Conclusions: Our data demostrated very high performance of diagnostic preoperative procedures due to multidisciplinary approach between the radiologists, the clinicians and the pathologists.

Processing Techniques

Breast cancer is one of the most common women cancers in the world. In this paper, a new approach based on thermography for the early detection of breast abnormality is proposed. The study involved 80 breast thermograms collected from the PROENG public database which consists of 50 healthy breasts and 30 with some findings. Image processing techniques such as segmentation, texture analysis and mathematical morphology were used to train a support vector machine (SVM) classifier for automatic detection of breast abnormality. After conducting several tests, we obtained very interesting and motivating results. Indeed, our method  showed a high performance in terms of sensitivity of 93.3%, a specificity of 90% and an accuracy of 91.25%. The final results let us conclude that infrared thermography with the help of an adequate automatic classification algorithm can be a valuable and reliable complementary tool for radiologist in detecting breast cancer and thereby helping to reduce mortality rates.

Abstract Background: Rapid diagnostic centres (RDC) for breast abnormality offer a speedier process from the discovery of a suspicious breast lump to same-day investigation and confirmation of a breast cancer diagnosis. Study purpose: We aim to assess the anxiety and uncertainty levels of women going through an RDC and explore women’s needs for support during the diagnostic period. Methods: Thirteen women who attended an RDC in 2014 took part in a sequential mixed-method study to assess anxiety and uncertainty levels. Measures were taken at pre and post-testing, at three weeks following receipt of results followed by a semi-structured telephone interview. Results: The mixed data results mainly showed congruence between women scoring high on anxiety and uncertainty levels and their detailed descriptions of the experience as stressful. Overall, uncertainty and anxiety levels were above the clinical threshold while awaiting further testing. These levels remained high only for the subgroup found with cancer and remained high at the three-week mark. As for the benign group, anxiety was above cut-off before diagnosis (n=6), decreased to below clinical cut-off three days following diagnosis (n=0), and increased again above cut-off three weeks post-diagnosis (n=2). Discussion and Conclusion: While speedier testing may reduce waiting times to obtain further tests, results suggest that the period leading up to the day of testing is anxiety-provoking and marked with intense uncertainty. Results suggest the potential role of nurses to support waiting for patients with education and resources. These results illustrate the need for further investigation into psychological support options at RDCs.
