Proteinemia as a Prognostic Factor in Colorectal Cancers beyond Surgery and Chemotherapy

Background: Globally, 1,096,601, 704,376, and 48,541 new colon, rectum, and anus cancer cases were recorded in 2018, respectively. Besides, 551,269, 310,394 and 19,129 cases of colon, rectum, and anus cancer deaths occurred in the same year. As a result, these cancers ranked in the third level of cancer incidence, and in the second level of cancer mortality. As it is known, all cancer patients are subjected to cancerinduced and therapy-induced nutritional deficiencies (mainly of proteins and calories). The present study aimed to assess proteins level in colorectal cancer (CRC) patients who underwent surgery and chemotherapy. Methods: A combined retrospective and prospective study was performed. The present study enrolled 100 CRC patients with their data on surgical procedures and chemotherapy management. Assessments of the studied samples were conducted as a baseline before receiving chemotherapy and preoperatively as P0, while the period after that was termed as P1. The serum samples were collected to measure protein concentration. Total Protein Kit, Micro was used. Results: The mean age of the patients was 50.7±12.88 years old. Only 8% had a positive CRC family history. Rectosigmoid cancer represented the most frequent site, figured in 41% of the cases, followed by rectum cancer. Multiple sites of CRC metastasis were recorded in 15% of the patients. All patients received chemoradiation. Folinic acid (leucovorin), 5-FU, and oxaliplatin (FOLFOX) was the most used regimen, administered in 40% of the patients. Oxaliplatin and capecitabine (also called Xeloda) (XELOX) were administered in 14% of the patients. Folinic acid (leucovorin), 5-FU, oxaliplatin, and irinotecan (FOLFOXIRI) were administered in 16% of the patients. Single-agent oxaliplatin or carboplatin were administered in 6% of the patients, each. 5-FU plus leucovorin was administered to 12% of the patients. Three patients received irinotecan, and oxaliplatin (IROX). One patient received folinic acid (leucovorin), 5-FU and irinotecan (FOLFIRI). Also, Gemzar was administered to two patients only. A total of 80% of the patients underwent several surgical procedures. Anterior perineal resection (APR) and total mesorectal excision (TME) were the most common two surgeries, performed in 20 and in 30% of the patients, respectively. In P0 status, 44% of the patients suffered from low protein levels, and 13% of the patients were within the normal level. These findings were statistically different (p=0.03). After CRC management (i.e., P1 status), 70% of the patients had protein deficiency. These results have strong significant differences (p=0.000). The mean of protein concentration declined gradually after management, from 8.82±0.9 μg/L to 6.210.78 μg/L, with a strong association between a reduction in proteins levels towards deficiency and surgical procedures and chemotherapy protocols (p=0.000). Conclusion: The incidence of CRC is increasing annually, and the chance of being diagnosed with this type of cancer has risen in recent years. In the present study, the male to female ratio was 1:1.5, and the 5th decade of life was themost common age for the diagnosis of CRC. A negative family history and bowel inflammatory diseases (IBD) history did not exclude people from exposure to the incidence of CRC. Colorectal cancer with localized and moderately differentiated adenocarcinoma were the most common types in the present work. Tumor distance from the anal verge seems to be very important and plays a significant role in the choosing of surgical intervention types and chemoradiation protocols. Colorectal cancer acts as a complex condition and, in addition to its management, nutritional state influences it in different mechanisms. Most patients suffered from hypoproteinemia after surgery and chemoradiation. As a result, alteration in the treatment outcomes, delaying in wound healing, and an increase in postoperative complications may occur. (AU)

Distinctive bone regeneration of calvarial defects using biphasic calcium phosphate supplemented ultraviolet-crosslinked collagen membrane

PURPOSE: To overcome several drawbacks of chemically-crosslinked collagen membranes, modification processes such as ultraviolet (UV) crosslinking and the addition of biphasic calcium phosphate (BCP) to collagen membranes have been introduced. This study evaluated the efficacy and biocompatibility of BCP-supplemented UV-crosslinked collagen membrane for guided bone regeneration (GBR) in a rabbit calvarial model.METHODS: Four circular bone defects (diameter, 8 mm) were created in the calvarium of 10 rabbits. Each defect was randomly allocated to one of the following groups: 1) the sham control group (spontaneous healing); 2) the M group (defect coverage with a BCP-supplemented UV-crosslinked collagen membrane and no graft material); 3) the BG (defects filled with BCP particles without membrane coverage); and 4) the BG+M group (defects filled with BCP particles and covered with a BCP-supplemented UV-crosslinked collagen membrane in a conventional GBR procedure). At 2 and 8 weeks, rabbits were sacrificed, and experimental defects were investigated histologically and by micro-computed tomography (micro-CT).RESULTS: In both micro-CT and histometric analyses, the BG and BG+M groups at both 2 and 8 weeks showed significantly higher new bone formation than the control group. On micro-CT, the new bone volume of the BG+M group (48.39±5.47 mm3) was larger than that of the BG group (38.71±2.24 mm3, P=0.032) at 8 weeks. Histologically, greater new bone area was observed in the BG+M group than in the BG or M groups. BCP-supplemented UV-crosslinked collagen membrane did not cause an abnormal cellular reaction and was stable until 8 weeks.CONCLUSIONS: Enhanced new bone formation in GBR can be achieved by simultaneously using bone graft material and a BCP-supplemented UV-crosslinked collagen membrane, which showed high biocompatibility and resistance to degradation, making it a biocompatible alternative to chemically-crosslinked collagen membranes.

Robotic-assisted laparoscopic excision of gossypiboma simulating bladder wall mass after 35 years of appendectomy

Gossypiboma or textiloma are terms commonly used to describe a retained sponge in the body that is composed of sponge invested within a layer of foreign body reaction in the form of an abscess or an aseptic fibrotic reaction. These cases are rarely reported despite an incidence of 1:1,000-1,500 of abdominal or pelvic surgery. We report a patient who presented with an incidental supravesical mass discovered upon work up for frequency and suprapubic pain. He had appendectomy 35 years ago. The mass was excised by robotic-assisted laparoscopic technique. The pathologic evaluation came as gossypiboma

Successful delivery by a cesarean section in a parturient with severe dilated cardiomyopathy, an implantable cardioverter defibrillator, and a repaired tetralogy of fallot

Repaired congenital heart disease has become more prevalent in women of childbearing age. We report an unusual case of a 24-year-old multigravida with a repaired tetralogy of Fallot, severe dilated cardiomyopathy, and implantable cardioverter defibrillator placement who was managed successfully by a cesarean section three times. This case underscores the impact of such events on maternal and fetal safety and the importance of a multidisciplinary approach in the management of pregnant patients with complex congenital and medical problems
