Background: Liver metastases are the leading cause of death in patients with colorectal cancer. Despite advances in chemotherapy, surgical resection of hepatic metastases is still considered the only curative options. However, the majority of patients have inoperable disease at presentation. Perioperative chemotherapy is the most successful way for improved selection of patients for resection. The aim of the study was to demonstrate if and to what extent does bevacizumab, introduced in chemotherapy, increase response rates, and development of liver metastases. Methods: Our study included 50 patients who were divided in two groups. The experimental group included patients who were treated with bevacizumab plus chemotherapy, and the control group included patients who were treated with chemotherapy only. Results: The comparison showed that the patients who were treated with bevacizumab became candidates for resection of liver metastases in higher percentage (85%:52%). In addition, distribution of patients regarding the development of metastases resulted in statistically significant difference. Ratio between the patients with good response from the experimental and the control group was 67%:39%. Ratio of patients with stable disease was 26%:48%, and of patients with progressive disease, it was 7%:3%. The estimate of margin after resection was statistically insignificant. Conclusion: Bevacizumab in combination with chemotherapy in therapy of liver metastases from primary colorectal cancer improves and increases response rates and development of liver metastases.

Objective: The study aimed to explore the efficacy of pharmacokinetic-based 5-fluorouracil dose management by plasma concentration test in advanced colorectal cancer treatment. Methods: 153 samples of advanced colorectal cancer patients were enrolled and randomly assigned to a control group and an experimental group. All patients received double-week chemotherapy with 5- fluorouracil (four weeks were used as one period), and chemotherapy duration ranged from 2 to 6 periods. In the first period, all patients were administered with the classic strategy of body surface area (BSA). Results: In the subsequent periods, the control group (77 samples) continued with BSA guided chemotherapy, while the experimental group (76 samples) received pharmacokinetic AUC-based chemotherapy. The efficacy and toxic side effects were assessed during chemotherapy, and survival was recorded in a follow-up. In the AUC experimental group, the rate of diarrhea significantly decreased (37.50% vs. 70.00%, P=0.010), and incidence of oral mucositis reduced (54.17% vs. 82.50%, P=0.014). Compared with the control group, the clinical benefit rate of experimental group was much higher (90.79% vs. 79.22%, P=0.046). Conclusion: There was no significant difference in other 5-fluorouracil related toxic side effect events (nausea, vomiting, hand-foot syndrome) and progression-free survival between the two groups. Pharmacokinetic- based dose management of 5-Fluorouracil reduces the toxicity of chemotherapy and improves long-term efficacy of chemotherapy for advanced colorectal cancer patients.

Abstract Background: Metformin reduces the risk of, and mortality from, colorectal cancer in patients with diabetes mellitus. However, the effect of metformin on patients with stage IV disease is unknown. In the present study we reviewed the clinical features and outcomes of patients with diabetes mellitus and stage IV colorectal cancer (M1, liver metastases) treated with or without metformin.Methods: The 202 patients with colorectal cancer and macroscopic liver metastasis who were treated in the Department of Surgery or Department of Clinical Oncology at Jichi Medical University Hospital from January 2006 through June 2019 were surveyed treatment of diabetes, clinical and pathological factor and prognosis of these patients. Results: We retrospectively examined the effect of metformin use on outcomes in 32 patients with liver metastases from colorectal cancer. Hepatic metastases were stage H1 in 8/8 patients taking metformin and stage H2-3 in 17/24 non-users. Of 22 patients who underwent colectomy, colorectal tumors were pT4 in 5 metformin users, and pT2-3 in 10/17 non-users. The mean survival of metformin users and non-users was equal (28.0 mo vs 29.3 mo, p>.05). No significant difference was detected when survival was compared between 6 metformin users and 19 non-users who received systemic chemotherapy. Conclusion: These results suggest that metformin has less potent anti-tumor effects in patients with advanced stage disease. Metformin for the treatment of patients with metastatic colorectal cancer requires further study.

e14072 Background: Colorectal cancer(CRC) with liver-only metastasis is considered potentially curable when liver metastases are completely resectable, while nonresectable liver metastases(NLM) are still incurable. In the latter cases, neoadjuvant chemotherapy could render curability by achieving resectability. We assessed efficacy of neoadjuvant cetuximab combined with FOLFOX6 in colorectal patients with NLM. Methods: Between July 2008 and Dec 2009, 73 patients were enrolled from 11 centers in Korea. Newly diagnosed K-RAS wild type CRC patients with NLM were treated with FOLFOX6 plus cetuximab(provided by Merck Serono) every 2 weeks. Response was evaluated every 3 cycles by CT scan according to RECIST 1.0. Chemotherapy was continued until disease progression or maximum of 12 cycles. Liver metastasectomy was performed at physician’s discretion in patients with enough tumor shrinkage, followed by chemotherapy of same regimen to complete total 12 cycles. The primary endpoint was overall R0 resection rate. The secondary endpoints were the response rates, progression-free survival(PFS), overall survival and toxicity. Results: In total, 73 patients were enrolled and analyzed. The median follow up duration was 28.6 months (range 11.5 to 38.1). Among 53 (72.6%) patients who showed response, surgery with curative intent was attempted in 36 (49.3%) patients. With intention-to-treat analysis, R0 resection rate(RR) was 19.2% (14/73), RFA plus R0, R1 and R2 RR were 8.2% (6/73), 8.2% (6/73), 13.7% (10/73), respectively. Despite neoadjuvant chemotherapy, 37 (50.7%) patients had unresectable hepatic metastases, however. RFA was successfully performed in combination with surgery (n=7) or alone (n=1) in 8 patients of them. Chemotherapy was discontinued in 26 patients due to disease progression (n=13), death (n=2), consent withdrawal (n=10), or protocol violation (n=1). The most common grade 3 and 4 toxicity was neutropenia (10.7%). Median PFS was 14.1 months (range 1.3 - 30.8) in patients received R0 resection and RFA + R0 resection. Conclusions: Neoadjuvant chemotherapy with FOLFOX6 plus cetuximab showed high response rates and increase resection rate in CRC patients with NLM.

The purpose of this non-random retrospective cohort study was to evaluate the impact of prophylactic antibiotic on early outcomes including postoperative pain, swelling, bleeding and cyanosis in patients undergoing dental implant placement before prosthetic loading. Seventy-five patients (45 males, 30 females) whose dental implant placement were completed, included to the study. Patients used prophylactic antibiotics were defined as the experimental group and those who did not, were defined as the control group. The experimental group received 2 g amoxicillin + clavulanic acid 1 h preoperatively and 1 g amoxicillin + clavulanic acid twice a day for 5 days postoperatively while the control group had received no prophylactic antibiotic therapy perioperatively. Data on pain, swelling, bleeding, cyanosis, flap dehiscence, suppuration and implant failure were analyzed on postoperative days 2, 7, and 14 and week 12. No statistically significant difference was detected between the two groups with regard to pain and swelling on postoperative days 2, 7, and 14 and week 12 ( p >0.05), while the severity of pain and swelling were greater on day 2 compared to day 7 and 14 and week 12 in both groups ( p =0.001 and p <0.05, respectively). Similarly, no significant difference was found between the two groups with regard to postoperative bleeding and cyanosis. Although flap dehiscence was more severe on day 7 in the experimental group, no significant difference was found between the two groups with regard to the percentage of flap dehiscence assessed at other time points. Within limitations of the study, it has been demonstrated that antibiotic use has no effect on implant failure rates in dental implant surgery with a limited number of implants. We conclude that perioperative antibiotic use may not be required in straightforward implant placement procedures. Further randomized control clinical studies with higher numbers of patients and implants are needed to substantiate our findings.

          Peer teaching is a strategy that allows the students to teach the new content to each other, and they must be accurately guided by instructors.     The researcher proposes that the use of students peer teaching  may promote students' achievement  and ensure the engagement of all the students in the learning process. Therefore, the researcher employs it as a teaching method aiming at investigating its  effect on Iraqi EFL students' achievement in the course of Library and Research Work .      The study hypothesizes that there is no significant difference between the students' achievement who are taught library and research work by students peer teaching  and that of the students taught by the traditional way. The experimental design of the study is Parallel Groups, Random Assignment, posttest. Each group consists of 35 students, chosen randomly from the Third Year Students at the Department of English in the College of Basic Education. Both groups were matched in terms of their age and parents' education. The experiment was fulfilled in the first course for 15 weeks during the academic year 2016-2017.       The same materials were presented to both groups. This included   units from Writing Research Paper by Lester D. . Post-test was constructed and exposed  The t-test for  independent samples was used to analyze the results and it is found out that there is a statistical difference between the two groups in their achievement because the calculated t- value 2.635 is bigger than the tabulated t- value which is 2.000, and also shown the superiority of the experimental group. The results indicate that the experimental group, who was taught Library and Research Work by peer teaching   was better than the control group, who was taught according to the traditional way. So, the null hypothesis is rejected. Finally, some recommendations and suggestions are presented in the light of the study findings. to a jury of experts to verify its validity and it was administered to both groups.

Topicality: The result of surgical treatment depends largely on the chosen method of management of the postoperative period, the main purpose of which is to reduce the effects of surgical trauma. Despite the wide variety of drugs for local and systemic use, the question of pharmacotherapy of the operated sinus remains open to this day. The main properties that a modern drug should possess are safety and high clinical efficacy. Aim: to study the clinical efficacy of topical application of a complex preparation based on a saline solution containing sodium hyaluronate and dexpanthenol in patients with chronic sinusitis after functional endoscopic sinus surgery (FESS). Materials and Methods: Clinical and laboratory studies were conducted on 47 patients with chronic rhinosinusitis who underwent surgery using the FESS technique. Patients were divided into 2 groups according to the principle of the postoperative period. Patients of research group (n=21), except for traditional therapy, was used locally NASOMER (a preparation based on a water-salt solution containing sodium hyaluronate and dexpanthenol); to the control group (n=26) patients entered, in the postoperative period received traditional therapy. Traditional therapy included a toilet of the nasal cavity, the use of short-course topical decongestants, irrigation of the nasal cavity with water-salt solutions. Criteria of clinical effectiveness: data of endoscopy of the nasal cavity, rhinomanometry, activity of the mucociliary transport system. The effectiveness of functional research methods in the postoperative period was determined on the 7th and 14th day of treatment. Results: On the 3rd day of the study, an increase in the swelling of the nasal cavity was observed in patients of both clinical groups, correlated with difficulty in nasal breathing. On the 7th day, a decrease in edema was observed in patients of both groups, but in the experimental group, the index of nasal breathing, according to rhinomanometry, was significantly (p<0.05) different from the control group, and was respectively 1.54±0.14 and 2.04±0.19 kPa/l*s. On the 14th day of the study, no significant difference was observed between these indicators. When studying the activity of the ciliated epithelium of the mucous membrane of the nasal cavity, it was proved that patients of the experimental group on day 7 after surgery showed a statistically significant difference in this indicator compared to the control group (17.8±1.0 and 22.7±2.1 min. respectively). Conclusions: The use of NASOMER after surgical intervention in patients with chronic rhinosinusitis contributes to more effective treatment compared with traditional therapy, as evidenced by the rapid recovery of the main functional parameters according to active posterior rhinomanometry and mucociliary clearance. Based on the results of the studies performed, the use of NASOMER for pharmacotherapy in the postoperative period is recommended for patients who have undergone rhinosurgical interventions with the aim of reducing the period of postoperative rehabilitation as an effective anti-inflammatory and wound-healing agent.

Aims: Investigation thyroid dysfunction and autoimmunity in pregnant women with gestational diabetes mellitus. Background: This article was written to evaluate the thyroid function and anti-thyroid peroxidase (anti- TPO) antibodies in pregnant women with gestational diabetes mellitus (GDM). Method: A total of 252 women with GDM and 252 healthy pregnant women were enrolled. Thyroid tests, including TSH, FreeT3, Free T4, and anti-TPO were performed for all women at 24–28 weeks of gestation. Data analysis was then carried out using SPSS ver. 22. Result: There was a significant difference between the experimental group (38.4%) and the control group (14.06%) in terms of the prevalence of subclinical hypothyroidism (p= 0.016). The frequency of anti-TPO was higher in the experimental group than the control group and positive anti-TPO was observed in 18.6% of women with GDM and 10.3% of healthy pregnant women (P= 0.008). Conclusion: Thyroid disorders are observed in pregnant women with GDM more frequently than healthy individuals and it may be thus reasonable to perform thyroid tests routinely.

Objective: India is the second country after China having the highest population prevalence of diabetes. Several research studies investigating diabetes have been done, but not much work has been done on prediabetes. The purpose of this study was to investigate the effect of nutrition and lifestyle modification on prediabetic females. Methods: A total of 120 prediabetic females from Ludhiana city were divided into 2 matched groups: control group (n = 60) and experimental group (n = 60). Impact of nutrition intervention for dietary and lifestyle modification (for 3 months) was assessed on the anthropometric, dietary, biochemical parameters, and diabetes risk score of the experimental group and control group (no intervention). Results: All the selected 120 subjects completed the study (experimental group = 60; control group = 60). There was significant difference in the changes between the 2 groups throughout the study. The fasting blood glucose and glycated hemoglobin A1c levels of the experimental group subjects reduced significantly ( P ≤ .01). However, no change was observed among the control group subjects. The lipid profile of the experimental group showed a significant improvement ( P ≤ .01). Conclusion: Nutrition counselling of the prediabetics regarding dietary and lifestyle modification is recommended so as to improve their metabolic control, thus preventing them from being diabetics.
