Younger age as a prognostic indicator in breast cancer: A cohort study
<p>Abstract</p> <p>Background</p> <p>The debate continues as to whether younger women who present with breast cancer have a more aggressive form of disease and a worse prognosis. The objectives of this study were to determine the incidence of breast cancer in women under 40 years old and to analyse the clinicopathological characteristics and outcome compared to an older patient cohort.</p> <p>Methods</p> <p>Data was acquired from a review of charts and the prospectively reviewed GUH Department of Surgery database. Included in the study were 276 women diagnosed with breast cancer under the age of forty and 2869 women over forty. For survival analysis each women less than 40 was matched with two women over forty for both disease stage and grade.</p> <p>Results</p> <p>The proportion of women diagnosed with breast cancer under the age of forty in our cohort was 8.8%. In comparison to their older counterparts, those under forty had a higher tumour grade (p = 0.044) and stage (p = 0.046), a lower incidence of lobular tumours (p < 0.001), higher estrogen receptor negativity (p < 0.001) and higher <it>HER2 </it>over-expression (p = 0.002); there was no statistical difference as regards tumour size (p = 0.477). There was no significant difference in overall survival (OS) for both groups; and factors like tumour size (p = 0.026), invasion (p = 0.026) and histological type (p = 0.027), PR (p = 0.031) and <it>HER2 </it>(p = 0.002) status and treatment received were independent predictors of OS</p> <p>Conclusion</p> <p>Breast cancer in younger women has distinct histopathological characteristics; however, this does not result in a reduced survival in this population.</p
A Genome-Wide Gene Function Prediction Resource for Drosophila melanogaster
Predicting gene functions by integrating large-scale biological data remains a challenge for systems biology. Here we present a resource for Drosophila melanogaster gene function predictions. We trained function-specific classifiers to optimize the influence of different biological datasets for each functional category. Our model predicted GO terms and KEGG pathway memberships for Drosophila melanogaster genes with high accuracy, as affirmed by cross-validation, supporting literature evidence, and large-scale RNAi screens. The resulting resource of prioritized associations between Drosophila genes and their potential functions offers a guide for experimental investigations

Here, we compared open and laparoscopic total extraperitoneal (TEP) repairs under general (GA) and spinal anesthesia (SA).Methods: Inguinal hernia patients (n=440) were analyzed retrospectively. There were four groups: Group 1 was TEP under GA (TEP-GA) (n=111); Group 2 was open mesh repair (OM) under SA (n=116) (OM-SA); Group 3 was open mesh repair under GA (n=117) (OM-GA); Group four was TEP under SA (n=96) (TEP-SA). The age, body mass index, duration of operation, hospital stay, postoperative Visual Analog Scale scores, recurrence, postoperative pain, urinary retention, headache, and patient satisfaction were all recorded.Results: There was no significant difference in terms of hypotension, vomiting, seroma and scrotal edema, recurrence, and wound infection incidence between the groups. However, the operation duration, hospital stay period, headache, urinary retention, postoperative Visual Analog Scale scores, chronic pain, and patient satisfaction showed significant differences between groups.Conclusion: Laparoscopic TEP hernia repair is a safe and effective method along with its advantages of shorter hospital stay, less recurrence, less postoperative pain, higher patient satisfaction, and similar postoperative complication rates. SA has the disadvantage of higher incidence of headache and urinary retention compared to GA. Keywords: herniorrhaphy, laparoscopy, general anesthesia, spinal anesthesi
