Segmentation of prostate Cone Beam CT (CBCT) images is an essential step towards real-time adaptive radiotherapy (ART). It is challenging for Calypso patients, as more artifacts generated by the beacon transponders are present on the images. We herein propose a novel wavelet-based segmentation algorithm for rectum, bladder, and prostate of CBCT images with implanted Calypso transponders. For a given CBCT, a Moving Window-Based Double Haar (MWDH) transformation is applied first to obtain the wavelet coefficients...

PURPOSE: To study the dosimetric impact of deformable image registration-based contour propagation on MRI-based cervical cancer brachytherapy planning. METHODS AND MATERIALS: High-risk clinical target volume (HRCTV) and organ-at-risk (OAR) contours were delineated on MR images of 10 patients who underwent ring and tandem brachytherapy. A second set of contours were propagated using a commercially available deformable registration algorithm. "Manual-contour" and "propagated-contour" plans were optimized to achieve a maximum dose to the most minimally exposed 90% of the volume (D90) (%) of 6 Gy/fraction, respecting minimum dose to the most exposed 2cc of the volume (D2cc) OAR constraints of 5...

Epidemiology studies suggest associations between schizophrenia and cancer. However, the underlying genetic mechanisms are not well understood, and difficult to identify from epidemiological data. We investigated if there is a shared genetic architecture between schizophrenia and cancer, with the aim to identify specific overlapping genetic loci. First, we performed genome-wide enrichment analysis and second, we analyzed specific loci jointly associated with schizophrenia and cancer by the conjunction false discovery rate...

We have developed a dual-modality endoscope composed of photoacoustic (PA) and hyperspectral imaging, capable of visualizing both structural and functional properties of bio-tissue. The endoscope's composition and scanning mechanism was described, and the feasibility of the dual-modality endoscope was verified by mimic phantom experiments. Lately, we demonstrated its endoscopic workability through in vivo experiments. The experimental results showed that the proposed herein hybrid endoscope can provide optical imaging of the surface and tomography imaging for the deeper features, and a functional oxygen saturation rate map of the same imaging area...

Standard surgical treatment for patients operated for rectal cancer is abdominoperineal excision of the tumor result- ing in a permanent colostomy or an anterior resection, often with construction of a temporary loop ileostomy. Both options impact bowel function. Living with a permanent colostomy has been studied in depth, but knowledge is limited about patients' experiences living with a resected rectum after stoma reversal and how it affects daily life. A qualitative study was conducted to describe the rst 4 to 6 weeks after reversal of a temporary loop ileostomy due to rectal cancer...

INTRODUCTION: Familial Adenomatous Polyposis (FAP) is a hereditary condition characterized by multiple colorectal adenomatous polyps. FAP is the most common adenomatous polyposis syndrome. Restorative proctocolectomy is the most commonly performed surgical procedure performed for patients suffering from FAP with different options for anastomosis, namely ileorectal anastomosis (IRA) or ileal pouch anal anastomosis (IPAA). The occurrence of adenomas is a common finding during follow up and surveillance post surgery for these patients...

PURPOSE: Hypofractionated radiotherapy can reduce treatment durations and produce effects identical to those of conventionally fractionated radiotherapy for treating prostate cancer. Volumetric arc radiotherapy (VMAT) can decrease the treatment machine monitor units (MUs). Previous studies have shown that VMAT with multileaf collimator (MLC) rotation exhibits better target dose distribution. Thus, VMAT with MLC rotation warrants further investigation. METHODS AND MATERIALS: Ten patients with prostate cancer were included in this study...

Synchronous appearance of the primary gastrointestinal malignancies is rare. Coexistence of primary pancreatic and hepatocellular carcinoma as synchronous malignancy is even rarer. We report a case of such combination in a 50 year old female who presented with bleeding per rectum and while evaluating we found simultaneous appearance of primary malignancies of pancreas, liver and solitary colonic metastasis from the pancreas in the background of chronic calcific pancreatitis. To the best of our knowledge this combination of synchronous pancreatic and hepatocellular carcinoma and colonic metastasis from the pancreas is unique...

Approximately 907,000 Americans currently suffer from ulcerative colitis, a condition characterized by inflammation of the large intestine or rectum. Treatment of this disease often includes anti-inflammatory medication or immunosuppressants. Here foams are an attractive delivery platform, offering relatively high bioavailability, low systemic exposure, and improved patient comfort. However, the surfactants that generate these foams may adversely affect the diseased mucosa. Therefore, this project evaluated two alternative surfactants for use in topical drug delivery platforms: sodium caseinate and L-α-phosphatidylcholine...

A 3.5-year-old, neutered male pit bull dog was euthanized following an approximately 1-year history of intractable diarrhea and weight loss of undetermined cause. At necropsy, the dog was emaciated. The ratio of total intestinal length (duodenum to rectum) to crown-to-rump length was 2.5, in contrast to an average of 5.3 (range, 3.7-6.1) in 10 control dogs examined at necropsy. There was diffuse dilation of the intestinal lumen, consistent with congenital intestinal hypoplasia resulting in short-bowel syndrome...
