Maternal serum interlukin-6 level in preterm labor

Objective: The aim of this study was to measure interleukin-6 (IL-6) levels in maternal serum of women undergoing preterm labor without a clear infection. Materials and Methods: Twenty two pregnant women with diagnosis of preterm labor who presented to the outpatient clinic of 19 Mayıs University Faculty of Medicine from July 2011 through December 2011 were enrolled in the study group. Twenty two healthy pregnant women who were at the same gestational age as the study group were selected as the control group. Results: Gestational age in the study and control groups varied from 24 weeks and 4 days to 34 weeks and 6 days. In the study group, 11 patients (50%) underwent preterm birth. Pregnant women in preterm labor were compared to healthy pregnant women with regards to serum IL-6 levels. No significant difference was found in the IL-6 levels of maternal serum between the 2 groups. Conclusion: In this study, we have shown that there is no increase in IL-6 levels in patients undergoing preterm labor without clinical or biochemical infection signs

Goodbye Hartmann trial: a prospective, international, multicenter, observational study on the current use of a surgical procedure developed a century ago

Background: Literature suggests colonic resection and primary anastomosis (RPA) instead of Hartmann's procedure (HP) for the treatment of left-sided colonic emergencies. We aim to evaluate the surgical options globally used to treat patients with acute left-sided colonic emergencies and the factors that leading to the choice of treatment, comparing HP and RPA. Methods: This is a prospective, international, multicenter, observational study registered on ClinicalTrials.gov. A total 1215 patients with left-sided colonic emergencies who required surgery were included from 204 centers during the period of March 1, 2020, to May 31, 2020. with a 1-year follow-up. Results: 564 patients (43.1%) were females. The mean age was 65.9 ± 15.6 years. HP was performed in 697 (57.3%) patients and RPA in 384 (31.6%) cases. Complicated acute diverticulitis was the most common cause of left-sided colonic emergencies (40.2%), followed by colorectal malignancy (36.6%). Severe complications (Clavien-Dindo ≥ 3b) were higher in the HP group (P < 0.001). 30-day mortality was higher in HP patients (13.7%), especially in case of bowel perforation and diffused peritonitis. 1-year follow-up showed no differences on ostomy reversal rate between HP and RPA. (P = 0.127). A backward likelihood logistic regression model showed that RPA was preferred in younger patients, having low ASA score (≤ 3), in case of large bowel obstruction, absence of colonic ischemia, longer time from admission to surgery, operating early at the day working hours, by a surgeon who performed more than 50 colorectal resections. Conclusions: After 100 years since the first Hartmann's procedure, HP remains the most common treatment for left-sided colorectal emergencies. Treatment's choice depends on patient characteristics, the time of surgery and the experience of the surgeon. RPA should be considered as the gold standard for surgery, with HP being an exception

Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries

Abstract Background Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. Methods This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries. Results In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia. Conclusion This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries

Guided bone regeneration simultaneous with implant placement using bovine-derived xenograft with and without liquid platelet-rich fibrin: a randomized controlled clinical trial

Objective To assess augmentation success after guided bone regeneration (GBR) carried out simultaneously with implant placement using bovine-derived xenograft alone and in combination with liquid platelet-rich fibrin (liquid-PRF). Methods This randomized controlled clinical trial was conducted on patients with horizontal bone deficiency in the posterior regions of the mandible. After implant placement, GBR procedures were randomly performed using liquid-PRF-enriched bovine-derived xenograft (for the test group) and with bovine-derived xenograft alone (for the control group). To assess the change in augmentation thickness, the primary outcome of the study, cone beam computed tomography was carried out at the implant sites on completion and 6 months after surgery. The secondary outcomes were marginal bone level and implant survival rate at prosthetic delivery and at 6 months, 1 year, and 2 years follow-up after loading. The significance level was set at pResults Twenty patients with 50 implants were analyzed for the test group and 20 patients with 48 implants for the control group. At 6 months postoperatively, the mean values of augmentation thickness were 1.63 +/- 0.21 mm, 2.59 +/- 0.34 mm, and 3.11 +/- 0.36 mm for the test group and 1.34 +/- 0.14 mm, 2.49 +/- 0.24 mm, and 2.97 +/- 0.24 mm for the control group at 2 mm, 4 mm, and 6 mm below to the implant shoulder (p 0.001, p = 0.007, and p = 0.036, respectively). The mean marginal bone loss was found to be less than 1 mm for both study groups during the 2 years of follow-up after prosthetic loading. Implant survival rate was 100% for both study groups. Conclusion Bovine-derived xenograft alone and in combination with liquid-PRF are both successful in achieving bone augmentation around the implants and produce a small change in marginal bone level and a high implant survival rate after loading

uyanikgil, Yigit/0000-0002-4016-0522; KISAOGLU, Huseyin/0000-0002-3999-8846; isik, gozde/0000-0001-9572-3049; , meltem/0000-0002-7088-9701WOS:000623691700020Aim: To evaluate the effect on vertical bone augmentation of the screw tent-pole technique using particulate allograft in combination with injectable platelet-rich fibrin, and to compare this with autogenous block bone graft. Materials and Methods: This split-mouth randomized controlled study involved patients with bilateral partial edentulism and vertical bone loss in the posterior mandible. in each patient, the control side was treated with autogenous block bone graft harvested from the mandibular ramus and, on the test side, the screw tent-pole technique was employed, using particulate allograft in combination with injectable platelet-rich fibrin. All augmented sites were covered by leukocyte and platelet-rich fibrin membrane. The primary outcome variable of this study was the radiographic changes to bone height 6 months after augmentation. The secondary outcome variables were the percentage of newly formed bone and the implant survival rate. The data were analyzed with a significance level of alpha = 0.05. Results: of the 13 patients included, a total of 11 patients (7 females, 4 males; mean age 50.92) completed the study. The mean values of vertical bone gain were 1.72 0.78 mm for the test group and 2.83 +/- 0.89 mm for the control group, which constitutes a significant difference (P = .008). The percentage of newly formed bone was 18.08% +/- 2.17% for the test group and 14.26% +/- 1.76% for the control group. The difference between the groups was statistically significant (P < .001). The implant survival rates were 100% for both study groups. Conclusions: Based on the study results, screw tent-pole can be considered a feasible technique for bone augmentation. Further randomized studies will be necessary to fully evaluate vertical bone augmentation using the screw tent-pole technique, with different graft materials and with larger samples.Scientific Research Committee of the University [16-DIS-026]The authors disclosed receipt of the following financial support for the research, authorship, and/or publication of this article: This study was supported by the Scientific Research Committee of the University (16-DIS-026)

Feasibility of motor imagery and effects of activating and relaxing practice on autonomic functions in healthy young adults: A randomised, controlled, assessor-blinded, pilot trial

Introduction Motor imagery (MI) is the mental rehearsal of a motor task. Between real and imagined movements, a functional equivalence has been described regarding timing and brain activation. The primary study aim was to investigate the feasibility of MI training focusing on the autonomic function in healthy young people. Further aims were to evaluate participants' MI abilities and compare preliminary effects of activating and relaxing MI on autonomic function and against controls. Methods A single-blinded randomised controlled pilot trial was performed. Participants were randomised to the activating MI (1), relaxing MI (2), or control (3) group. Following a MI familiarisation, they practiced home-based kinaesthetic MI for 17 minutes, 5 times/week for 2 weeks. Participants were called once for support. The primary outcome was the feasibility of a full-scale randomised controlled trial using predefined criteria. Secondary outcomes were participants' MI ability using the Movement Imagery Questionnaire-Revised, mental chronometry tests, hand laterality judgement and semi-structured interviews, autonomic function. Results A total of 35 participants completed the study. The feasibility of a larger study was confirmed, despite 35% attrition related to the COVID-19 pandemic. Excellent MI capabilities were seen in participants, and significant correlations between MI ability measures. Interview results showed that participants accepted or liked both interventions. Seven major themes and insider recommendations for MI interventions emerged. No significant differences and negligible to medium effects were observed in MI ability or autonomic function between baseline and post-intervention measures or between groups. Conclusions Results showed that neither activating nor relaxing MI seems to change autonomic function in healthy individuals. Further adequately powered studies are required to answer open questions remaining from this study. Future studies should investigate effects of different MI types over a longer period, to rule out habituation and assess autonomic function at several time points and simultaneously with MI

Effect of concentrated growth factors on frequency of alveolar Osteitis following partially-erupted mandibular third molar surgery: a randomized controlled clinical study

isik, gozde/0000-0001-9572-3049WOS: 000563499900001PubMed: 32807173Background the aim of this prospective study was to assess the effectiveness of concentrated growth factors (CGF) in preventing the development of alveolar osteitis (AO) after the extraction of partially-erupted mandibular third molars. Methods Seventy patients (26 men and 44 women) 18 years or older (mean age 25.86; range 18-35) underwent 140 third molar extractions. All the patients presented with bilateral, partially-erupted mandibular third molars and underwent surgical extractions. in each case, one socket received CGF and the other served as a control. the predictor variable was the CGF application and the sides were categorized as 'CGF' and 'non-CGF'. the outcome variable was the development of AO during the first postoperative week. Other study variables included age and gender. Data were analyzed using Cochran's Q test with the significance level set at aPvalue less than 0.05. Results the overall frequency of AO was 11.4% for the control group. the frequency of AO in the CGF group was significantly lower than in the non-CGF group (p < 0.001). Conclusions Based on the results of this study, application of CGF fibrin gel may decrease the risk of AO development after mandibular third molar surgery

Fall Of Another Myth For Colon Cancer: Duration Of Symptoms Does Not Differ Between Right- Or Left-Sided Colon Cancers

Background/Aims: Patients with colorectal cancer continue to present with relatively advanced tumors that are associated with poor oncological outcomes. The aim of the present study was to assess the association between localization, symptom duration, and tumor stage. Materials and Methods: A prospective, multicenter cohort study was conducted on patients newly diagnosed with a histologically proven colorectal adenocarcinoma. Standardized questionnaire-interviews were performed. Data were collected on principal presenting symptoms, duration of symptoms (time to first presentation to a doctor and time to diagnosis) and treatment, diagnostic procedures, tumor site, and stage of the tumor (tumor, node, and metastasis (TNM)). Results: A total of 1795 patients with colorectal cancer were interviewed (mean age: 60.76 +/- 13.50 years, male patients: 1057, patients aged >50 years: 1444, colon/rectal cancer: 899/850, right side/left side: 383/1250, stage 0-1-2/stage 3-4: 746/923). No statistically significant correlations were found between duration of symptoms and either tumor site or stage. Principal presenting symptoms were significantly associated with left colon cancer. Patients who had “anemia,” “change in bowel habits,” “anal pruritus or discharge,” “ weight loss,” and “tumor in right colon” had a significantly longer symptom time. Conclusion: Symptom duration is not associated with localization, nor is the tumor stage. Diagnosis of colorectal cancer at an earlier stage may be best achieved by screening of the population.WoSPubMe
