- Abstract
Background: In recent years, delayed elective care and growing waiting lists increasingly resulted in postponed surgeries for patients with chronic back and leg pain., Objective: To develop, implement, and evaluate the feasibility of a triage tool for patients with chronic back and/or leg pain to identify those eligible for referral to spinal cord stimulation (SCS) consultation., Methods: A triage tool was developed, based on Dutch SCS guidelines, literature review and expert panel consultation. The triage process was detected and implemented in collaboration with a multidisciplinary team, prior to first orthopaedic consultation. Feasibility, reliability and predictive accuracy were analysed as part of the evaluation of the triage tool., Results: The triage indicators included: Pain location (leg/mixed), DN4 > 3, pain duration ≥ 3 months, leg pain ≥ back pain and NPRS leg pain ≥ 5. The triage tool was applied on patients on the orthopaedic waiting list, followed by a full orthopaedic review if they were not excluded. A total of 1025 orthopaedic patients with chronic back and leg pain were assessed with the triage tool. The triage tool was evaluated as feasible (mean System Usability Score 74.2 [SD 11.5]), reliable (inter-rater reliability [Fleiss' Kappa 0.79], intra-rater reliability [Cohen's Kappa 0.89]) and accurate (sensitivity [100%], specificity [98.8%], positive predictive value [40%] and negative predictive value [100%])., Conclusion: Early triage of potential SCS candidates potentially supports rapid and appropriate care allocation, shortens waiting list time and improves clinical outcomes. Future research should explore strategies to optimise the tool's performance in identifying patients most likely to benefit from SCS therapy., Significance: A novel triage tool was developed to identify patients with chronic back and leg pain for an early referral to SCS. This tool, evaluated for feasibility, reliability, and predictive accuracy, shows promise in reducing waiting times and improving patient selection. It can be a prelude to the further development of decision support for SCS and an acceleration in the care process for SCS candidates., (© 2025 The Author(s).

- Abstract
Purpose: To evaluate the predictive potency of a novel index combining the pan-immune-inflammatory index and hemoglobin levels (PIV/Hb) for the prevalence of radiation-induced trismus (RIT) in patients with locally advanced nasopharyngeal cancer (LA-NPC) receiving concurrent chemoradiotherapy (CCRT)., Methods: Data from 228 LA-NPC patients were retrospectively examined. Maximum mouth openings (MMO) were measured to confirm the presence of RIT, defined as MMOs ≤35 mm. Complete blood test results from the first day of CCRT were used to calculate PIV/Hb levels. A potential relationship between pretreatment PIV/Hb and the RIT status was evaluated using receiver operating characteristic (ROC) curve analysis., Results: Post-CCRT RIT was diagnosed in 20.2% of the patients. The ROC curve analysis determined 68.4 g/dL as the ideal PIV/Hb cutoff that effectively divided patients into two distinct groups (area under the curve: 94.7%; specificity: 86.4%; sensitivity: 87.4%). RIT was significantly more prevalent in the PIV/Hb > 68 group than in the PIV/Hb < 68 group (58.8% vs. 3.8%; P < 0.001). Multivariate logistic regression analysis showed that a pre-CCRT PIV > 68 was independently associated with significantly higher rates of RIT., Conclusion: Higher pretreatment levels of the novel PIV/Hb index predict increased RIT rates following definitive CCRT for LA-NPCs., Competing Interests: The authors declare that they have no conflicts of interest. The authors have not entered into any agreements that would hinder our access to the research data, independent analysis, manuscript preparation, or publication., (Copyright © 2024 Efsun Somay et al.)

- Abstract
Objectives: We explored the prognostic utility of the unique combination of C-reactive-protein-to-albumin ratio (CAR) and significant weight loss (WL > 5%) over the preceding 6 months, namely, the CARWL score, in stage IIIC non-small-cell lung cancer (NSCLC) patients who underwent concurrent chemoradiotherapy (CCRT)., Methods: For each patient, the CAR was calculated using C-reactive protein and albumin measurements obtained on the first day of CCRT: CAR = C-reactive protein ÷ albumin. The availability of an ideal CAR cutoff that may categorize patients into two distinct progression-free (PFS) and overall survival (OS) outcomes was explored by employing receiver operating characteristic (ROC) curve analysis. Patients were additionally divided into two groups based on their status of significant WL according to the well-recognized Delphi criteria. Then, the CARWL score was created by combining all feasible combinations of the CAR and significant WL groupings. The potential links between pretreatment CARWL groups and the post-CCRT OS and PFS outcomes were determined as the primary and secondary endpoints., Results: This retrospective cohort study comprised a total of 651 stage IIIC NSCLC patients. ROC curve analysis indicated that rounded 3.0 was the ideal CAR cutoff (area under the curve (AUC): 70.1%; sensitivity: 67.8%; specificity: 65.9%), which categorized the patients into CAR < 3.0 ( N = 324) and CAR ≥ 3.0 ( N = 327) groups. There were 308 (47.3%) and 343 (52.7%) patients without and with significant WL, respectively. The created CARWL groups were CARWL-0: CAR < 3.0 and WL ≤ 5.0%; CARWL-1: CAR < 3.0 and WL > 5.0%, or CAR ≥ 3.0 and WL ≤ 5.0%; and CARWL-2: CAR > 3.0 and WL > 5.0%. The Kaplan-Meier curves showed that the PFS (14.2 vs. 11.4 vs. 7.5 months; P < 0.001) and OS (37.3 vs. 23.6 vs. 12.8 months; P < 0.001) durations were gradually and significantly lowered from the CARWL-0 to CARWL-2 groups. The CARWL score's significant impacts on PFS and OS outcomes were found to be independent of the other variables in the multivariate analysis ( P < 0.001, for each)., Conclusions: Our findings indicate that the novel CARWL score, which accounts for pretreatment CAR and significant WL during the preceding 6 months, can reliably stratify newly diagnosed stage IIIC NSCLC patients into three groups with significantly different PFS and OS after definitive CCRT., Competing Interests: The authors declare that they have no conflicts of interest., (Copyright © 2024 Erkan Topkan et al.)

- Abstract
Objective: Haemophagocytic lymphohistiocytosis (HLH) and macrophage activation syndrome (MAS) are life-threatening systemic hyperinflammatory syndromes that can develop in most inflammatory contexts. They can progress rapidly, and early identification and management are critical for preventing organ failure and mortality. This effort aimed to develop evidence-based and consensus-based points to consider to assist clinicians in optimising decision-making in the early stages of diagnosis, treatment and monitoring of HLH/MAS., Methods: A multinational, multidisciplinary task force of physician experts, including adult and paediatric rheumatologists, haematologist/oncologists, immunologists, infectious disease specialists, intensivists, allied healthcare professionals and patients/parents, formulated relevant research questions and conducted a systematic literature review (SLR). Delphi methodology, informed by SLR results and questionnaires of experts, was used to generate statements aimed at assisting early decision-making and optimising the initial care of patients with HLH/MAS., Results: The task force developed 6 overarching statements and 24 specific points to consider relevant to early recognition of HLH/MAS, diagnostic approaches, initial management and monitoring of HLH/MAS. Major themes included the simultaneous need for prompt syndrome recognition, systematic evaluation of underlying contributors, early intervention targeting both hyperinflammation and likely contributors, careful monitoring for progression/complications and expert multidisciplinary assistance., Conclusion: These 2022 EULAR/American College of Rheumatology points to consider provide up-to-date guidance, based on the best available published data and expert opinion. They are meant to help guide the initial evaluation, management and monitoring of patients with HLH/MAS in order to halt disease progression and prevent life-threatening immunopathology., (© 2023 American College of Rheumatology.)

- Abstract
Objective: The purpose of this study was to investigate the serum levels of mitochondrial metabolism/reactive oxygen species (ROS)-related peptides (hypoxia inducible factor-1α [HIF-1α], fibroblast growth factor-21 [FGF-21], growth differentiation factor-15 [GDF-15]) and key migraine-related neuropeptides (calcitonin gene-related peptide [CGRP], pituitary adenylate cyclase-activating peptide-38 [PACAP-38], substance P [SP], and vasoactive intestinal peptide [VIP]) during migraine attacks and to evaluate their diagnostic value in pediatric migraine., Background: There is increasing evidence for the important role of impairment in oxidative mitochondrial metabolism in the pathophysiology of migraine. Potential biomarkers that may reflect the relationship between migraine and mitochondrial dysfunction are unclear., Methods: A total of 68 female pediatric migraine patients without aura and 20 female healthy controls aged 8-18 years, admitted to the hospital, were enrolled in this cross-sectional study. Serum concentrations of these molecules were determined by enzyme-linked immunosorbent assays, and clinical features and their possible diagnostic value were analyzed., Results: Serum levels of HIF-1α (252.4 ± 51.9 [mean ± standard deviation]) pg/mL), GDF-15 (233.7 ± 24.7 pg/mL), FGF-21 (96.1 ± 13.1 pg/mL), CGRP (44.5 ± 11.3), and PACAP-38 (504.7 ± 128.9) were significantly higher in migraine patients compared to healthy controls (199.8 ± 26.8, 192.8 ± 20.7, 79.3 ± 4.1, 34.1 ± 3.5 and 361.2 ± 86.3 pg/mL, respectively). The serum levels of these peptides were also higher in patients with chronic migraine than in patients with episodic migraine, and higher in the ictal period than in the interictal period. A positive correlation was found between attack frequency and both HIF-1α and FGF-21 levels in migraine patients. Serum levels of VIP and SP were not different between the migraine patients and healthy controls., Conclusion: Migraine attacks are accompanied by elevated HIF-1α, FGF-21, GDF-15, CGRP, and PACAP-38 in medication-naive pediatric patients with migraine. Elevated circulating mitochondrial metabolism/ROS-related peptides suggest a mitochondrial stress in pediatric migraine attacks and may have potential diagnostic value in monitoring disease progression and treatment response in children. Novel approaches intervening with mitochondrial metabolism need to be investigated., (© 2023 The Authors.

- Abstract
Background: The evaluation of body composition is an essential parameter for preventing obesity and sarcopenic obesity, which are prognostic factors in breast cancer. This study aims to validate the bioelectrical impedance analysis (BIA) of women who are breast cancer survivors by using the dual-energy x-ray absorptiometry (DXA) measurement method., Methods: This validation study included 104 women without metastasis between 32 and 72 years old (mean 47.03 ± 8.59) whose treatment was completed 6 months prior. Body composition analysis was performed sequentially using both measurements and when participants were hungry., Results: Meaningful differences were found in fat-free mass (FFM) (BIA: 46.57 ± 5.54 kg; DXA: 41.06 ± 5.11 kg), body fat percentage (%BF) (BIA: 34.28% ± 6.24%; DXA: 43.91% ± 5.58%), body fat mass (FM) (BIA: 25.37 ± 8.84 kg; DXA: 31.24 ± 9.09 kg), and lean soft tissue mass (LSTM) (BIA: 4.42 ± 5.66 kg; DXA: 38.75 ± 4.98 kg) (P < 0.001). Powerful associations for body FM and strong associations for other parameters were seen. A constant and/or proportional error was found between the two devices within the direction of strong and solid components. Compared with DXA, the BIA measurement gives a lower estimate of %BF and FM and a higher estimate of LSTM and FFM., Conclusions: By the mathematical relationship between the two measurement methods, it seems possible to adapt the body composition parameters obtained from BIA of patients with breast cancer to DXA results. In the future, there will be a need to evaluate these two devices with more extensive studies., (© 2022 The Authors.

- Abstract
Background: Premature ventricular complex (PVC) is a frequent finding in the general population. The atrial conduction time (ACT) is the period between the electrocardiographic P wave and the atrial mechanical contraction, and its prolongation indicates an atrial electromechanical delay (EMD). In our study, we compared atrial conduction parameters by echocardiographic methods between patients with frequent PVC and healthy control subjects., Methods: The study included 54 patients with PVC and 54 healthy volunteers. Atrial conduction parameters were measured with echocardiographic examination. The time difference between the p wave and the Am wave was measured in the septal, lateral, and tricuspid annulus regions. The interatrial EMD, left atrial intra-atrial delay, and the right atrial intra-atrial delay were calculated from these measurements. The groups were compared for demographic and electrocardiographic features and echocardiographic parameters., Results: Left intra-atrial EMD, right intra-atrial EMD, and interatrial EMD were significantly longer in the patient group ( p = .001, p < .001, p < .001, respectively). PA lateral, PA septal, and PA tricuspid durations were significantly prolonged in the patient group (all p < .001). All ACT parameters were significantly prolonged in patients with PVC QRS duration of 150 ms and above (all p < .001). All ACT parameters were prolonged in PVCs of right ventricular origin than those of left ventricular origin (all p < .001). ACT parameters were prolonged in patients with a coupling interval time below 485 ms (all p < .001)., Conclusions: Atrial conduction times are prolonged in patients with frequent PVC., Competing Interests: The work will be presented at the “European Society of Cardiology (ESC) Congress 2022, Barcelona” as an oral moderated poster presentation and will be published as an abstract in the supplement of the European Heart Journal., (© 2023 The Authors.

- Abstract
Objectives: The purpose of this study was to determine the predictive significance of pretreatment pan-immune-inflammation value (PIV) in patients with newly diagnosed glioblastoma multiforme (GBM) who received postsurgical radiation (RT) and concurrent plus adjuvant temozolomide (TMZ)., Methods: The outcomes of 204 newly diagnosed GBM patients were analyzed retrospectively. Each eligible patient's PIV was calculated using the findings of peripheral blood platelet (P), monocyte (M), neutrophil (N), and lymphocyte (L) counts obtained on the first day of therapy: PIV = P × M × N ÷ L . We used receiver operating characteristic (ROC) curve analysis to discover the ideal cutoff values for PIV concerning progression-free (PFS) and overall survival (OS) outcomes. The primary and secondary end-points were the OS and PFS divergences across the PIV groups., Results: In ROC curve analysis, the optimal PIV cutoff was 385, which substantially interacted with PFS and OS results and categorized patients into low PIV (L-PIV; N = 75) and high PIV (H-PIV; N = 129) groups. Comparative survival analyses showed that the patients in the H-PIV group had significantly shorter median PFS (6.0 vs. 16.6 months; P < 0.001) and OS (11.1 vs. 22.9 months; P < 0.001) durations than those in the L-PIV group. The results of multivariate Cox regression analysis indicated an independent and significant connection between an H-PIV measure and shorter PFS and OS outcomes., Conclusions: The novel PIV was able to independently stratify newly diagnosed GBM patients into two groups with fundamentally different PFS and OS outcomes following RT and concurrent plus adjuvant TMZ., Competing Interests: The authors declare that there are no conflicts of interest regarding the publication of this paper., (Copyright © 2022 Erkan Topkan et al.)

- Abstract
Mycoplasma pneumoniae ( M . pneumoniae ) is one of the leading causes of community-acquired pneumonia in children and is also implicated in a variety of reactive extrapulmonary diseases. Recurrent and/or severe respiratory infections are one of the most frequent manifestations of several types of primary immunodeficiency. Here, we reviewed the medical literature to assess the potential relevance of M . pneumoniae in the infections observed in children affected with combined, humoral, and innate primary immune deficiencies. M . pneumoniae does not result to be epidemiologically prevalent as a cause of pneumonia in children affected by primary immunodeficiencies, but this infection can have a persistent or severe course in this category of patients. Indeed, the active search of M . pneumoniae could be useful and appropriate especially in children with humoral immune deficiencies. Indeed, most cases of M . pneumoniae infection in primary immunodeficiencies are described in patients affected by a/hypo-gammaglobulinemia., Competing Interests: The authors have no conflicts of interest to declare., (Copyright © 2022 Dimitri Poddighe et al.)

- Abstract
Background: The interleukin-1 (IL-1) mediated systemic autoinflammatory diseases, including the cryopyrin- associated periodic syndromes (CAPS), tumour necrosis factor receptor-associated periodic syndrome (TRAPS), mevalonate kinase deficiency (MKD) and deficiency of the IL-1 receptor antagonist (DIRA), belong to a group of rare immunodysregulatory diseases that primarily present in early childhood with variable multiorgan involvement. When untreated, patients with severe clinical phenotypes have a poor prognosis, and diagnosis and management of these patients can be challenging. However, approved treatments targeting the proinflammatory cytokine IL-1 have been life changing and have significantly improved patient outcomes., Objective: To establish evidence-based recommendations for diagnosis, treatment and monitoring of patients with IL-1 mediated autoinflammatory diseases to standardise their management., Methods: A multinational, multidisciplinary task force consisting of physician experts, including rheumatologists, patients or caregivers and allied healthcare professionals, was established. Evidence synthesis, including systematic literature review and expert consensus (Delphi) via surveys, was conducted. Consensus methodology was used to formulate and vote on statements to guide optimal patient care., Results: The task force devised five overarching principles, 14 statements related to diagnosis, 10 on therapy, and nine focused on long-term monitoring that were evidence and/or consensus-based for patients with IL-1 mediated diseases. An outline was developed for disease-specific monitoring of inflammation-induced organ damage progression and reported treatments of CAPS, TRAPS, MKD and DIRA., Conclusion: The 2021 EULAR/American College of Rheumatology points to consider represent state-of-the-art knowledge based on published data and expert opinion to guide diagnostic evaluation, treatment and monitoring of patients with CAPS, TRAPS, MKD and DIRA, and to standardise and improve care, quality of life and disease outcomes., (© 2022 American College of Rheumatology.

- Abstract
Background: Among the chronic diseases, chronic kidney failure is one of diseases that have the most difficulty in coping with oxidative stress due to the deterioration of the antioxidant system balance in the body. Beyond being a vitamin, 1 α ,25-dihydroxycholecalciferol (vitamin D3) is a molecule that positively or negatively affects many enzymes which are in protein structures. Thioredoxin (TRX), which has an important role in the antioxidant system, is one of these proteins. By conducting this study, we wanted to emphasize the role of vitamin D3 in reducing the oxidative stress load on patients undergoing peritoneal dialysis (PD) via serum TRX level measurement., Methods: In this study, we evaluated the medical treatments of 69 PD patients who were followed up routinely. The patients were divided into 2 groups according to whether they used vitamin D3 or not. 49 of our patients were using vitamin D3. While requesting routine laboratory tests, we reserved a separate serum sample to measure serum TRX levels by double-antibody sandwich enzyme-linked immunosorbent assay for all patients., Results: Only one parameter has a significant statistical relationship with serum TRX level and the treatment protocol. The serum TRX level was significantly higher (211,62 U/l ± 314,46) in the group receiving vitamin D3 compared to the group which is not using Vitamin D3 (101,63 U/l ± 215,03) ( p < 0,006)., Conclusion: This study highlights the importance of appropriate dose of vitamin D3 replacement especially in PD patients who are under intense oxidative stress compared to healthy individuals., Competing Interests: The authors declare that they have no conflicts of interest., (Copyright © 2022 Sara Yavuz Ileri et al.)

- Abstract
Fibroblasts of the gingiva play a key role in oral wound healing in diabetes. In this study, effects of astaxanthin (ASTX), a xanthophyll carotenoid, were tested on gingival fibroblasts in a wound healing assay in vitro. The aim of this study was to determine whether ASTX can recover delayed wound healing or not when oxidative stress is elevated by high glucose exposure. For this purpose, human gingival fibroblasts were incubated with or without ASTX following exposure to systemic doses of low glucose (LG) and high glucose (HG) in culture media (5- and 25-, 50 mM D-glucose in DMEM Ham's F12) following 24 hours of incubation. Levels of ROS (Reactive oxygen species) were determined for each experimental group by confocal microscopy. Cell proliferation and viability were assessed by an automated cell counter with trypan blue assay. Wound healing assay was designed in 60 mm petri dishes. Cells were exposed to 5-, 25-, and 50 mM glucose for 24 hours, and a straight line free of cells was created upon full confluency. 100 μ M ASTX was added to the recovery group, simultaneously. Cells were monitored with JuLI

ROS levels were significantly increased with increasing glucose levels, while cell proliferation and viability demonstrated a negative correlation with increasing oxidative stress. ROS levels significantly decreased in the 100 μ M ASTX-treated group compared to the gingival fibroblasts treated with 50 mM HG medium-only, as well as growth rate and viability. Wound healing was delayed in a dose-dependent manner following high glucose exposure, while ASTX treatment recovered wounded area by 1.16-fold in the 50 mM HG group. Our results demonstrated that ASTX enhances gingival wound healing through its antioxidative properties following high glucose induced oxidative stress. Therefore, ASTX can be suggested as a promising candidate to maintain oral health in chronic wounds of the oral tissues related to diabetes., Competing Interests: The authors declare that they have no conflicts of interest., (Copyright © 2022 Duru Aras-Tosun et al.)- Published

- Abstract
Materials and Methods: Our retrospective research included a sum of 126 LAPAC patients who received CCRT. The NLR was calculated for each patient based on the complete blood count test results obtained on the last day of the CCRT. The availability of optimal cutoff(s) that might dichotomize the whole cohort into two groups with significantly different clinical outcomes was searched using receiver operating characteristic (ROC) curve analysis. Primary and secondary endpoints were the potential association between the post-CCRT NLR measures and distant metastasis-free survival (DMFS) and overall survival (OS) outcomes., Results: The median follow-up duration was 14.7 months (range: 2.4-94.5). The median and 3-year OS and DMFS rates for the whole group were 15.3 months (95% confidence interval: 12.4-18.2) and 14.5%, and 8.7 months (95% CI: 6.7-10.7) and 6.3% separately. The ROC curve analysis findings separated the patients into two groups on a rounded NLR cutoff of 3.1 (area under the curve (AUC): 75.4%; sensitivity: 74.2%; specificity: 73.9%) for OS and DMFS: NLR <3.1 ( N = 62) and NLR ≥3.1 ( N = 64), respectively. Comparisons between the NLR groups displayed that the median OS (11.4 vs. 21.4 months; P < 0.001) and DMFS (6.0 vs. 16.0 months; P < 0.001) lengths were significantly shorter in the NLR ≥3.1 group than its NLR <3.1 counterparts, as well as the 3-year actuarial DM rate (79.7% vs. 50.0%; P =0.003). The N1-2 nodal stage, CA 19-9>90 U/mL, and NLR >3.1 were found to be independent predictors of poor prognosis in the multivariate analysis., Conclusion: The present study found that the posttreatment NLR ≥3.1 was independently linked with a higher risk of DM and subsequent degraded survival outcomes in unresectable LAPAC patients managed with exclusive CCRT., Competing Interests: The authors declare no conflicts of interest., (Copyright © 2022 Erkan Topkan et al.)

- Abstract
Aim: To evaluate the clinical factors associated with false-negative RT-PCR results and to report the outcome of a cohort of pregnant women with COVID-19., Methods: This cohort study was conducted in a tertiary referral pandemic hospital and included 56 pregnant women. A study including pregnant women with either a laboratory or clinical diagnosis for COVID-19 were included in the study. The primary outcome was clinical factors associated with false-negative RT-PCR results defined as a positive immunoglobulin M assessed by rapid testing in clinically diagnosed patients. Clinical outcomes of laboratory diagnosed patients were also reported., Results: In total, 56 women with either RT-PCR or clinical COVID-19 diagnosis were included in the study. Forty-three women either had RT-PCR positivity or IgM positivity. The clinical outcome of these pregnancies was as follows: mean maternal age 27.7, immunoglobulin M positive patients 76.7%, RT-PCR positive patients 55.8%, maternal comorbidities 11.5%, complications in patients below 20 weeks 34.8%, complications in patients above 20 weeks 65.1%, elevated CRP 83.7%, lymphopenia 30.2%, time from hospital admission to final follow-up days 37 and stillbirth 8.3%. The proportion of women who tested positive for SARS-CoV-2 immunoglobulin M was 100% in the RT-PCR positive group and 56.5% in the clinical diagnosis group (P = .002). The symptom onset to RT-PCR testing interval longer than a week (risk ratio: 2.72, 95% CI: 1.14-5.40, P = .003) and presence of dyspnoea (risk ratio: 0.38, 95% CI: 0.14-0.89, P = .035) were associated with false-negative RT-PCR tests. The area under the curve of these parameters predicting false-negative RT-PCR was 0.73 (95% CI: 0.57-0.89)., Conclusions: Symptomatic women with a negative RT-PCR should not be dismissed as potential COVID-19 patients, especially in the presence of prolonged symptom onset-test interval and in women without dyspnoea., (© 2021 John Wiley & Sons Ltd.)

- Abstract
Objective: Older adults with co-morbidities have been reported to be at higher risk for adverse outcomes of coronavirus disease 2019 (COVID-19). The characteristics of COVID-19 in older patients and its clinical outcomes in different kidney disease groups are not well known., Methods: Data were retrieved from a national multicentric database supported by Turkish Society of Nephrology, which consists of retrospectively collected data between 17 April 2020 and 31 December 2020. Hospitalised patients aged 18 years or older with confirmed COVID-19 diagnosis suffering from stage 3-5 chronic kidney disease (CKD) or on maintenance haemodialysis (HD) treatment were included in the database. Non-uraemic hospitalised patients with COVID-19 were also included as the control group., Results: We included 879 patients [388 (44.1%) female, median age: 63 (IQR: 50-73) years]. The percentage of older patients in the CKD group was 68.8% (n = 188/273), in the HD group was 49.0% (n = 150/306) and in the control group was 30.4% (n = 70/300). Co-morbidities were higher in the CKD and HD groups. The rate of presentation with severe-critical disease was higher in the older CKD and HD groups (43.6%, 55.3% and 16.1%, respectively). Among older patients, the intensive care unit (ICU) admission rate was significantly higher in the CKD and HD groups than in the control group (38.8%, 37.3% and 15.7%, respectively). In-hospital mortality or death and/or ICU admission rates in the older group were significantly higher in the CKD (29.3% and 39.4%) and HD groups (26.7% and 30.1%) compared with the control group (8.6% and 17.1%). In the multivariate analysis, in-hospital mortality rates in CKD and HD groups were higher than control group [hazard ratio (HR): 4.33 (95% confidence interval [CI]: 1.53-12.26) and HR: 3.09 (95% CI: 1.04-9.17), respectively]., Conclusion: Among older COVID-19 patients, in-hospital mortality is significantly higher in those with stage 3-5 CKD and on maintenance HD than older patients without CKD regardless of demographic characteristics, co-morbidities, clinical and laboratory data on admission., (© 2021 John Wiley & Sons Ltd.)

- Abstract
Objective: Behçet's disease is a complex systemic inflammatory vasculitis of incompletely understood etiology. This study was undertaken to investigate genetic associations with Behçet's disease in a diverse multiethnic population., Methods: A total of 9,444 patients and controls from 7 different populations were included in this study. Genotyping was performed using an Infinium ImmunoArray-24 v.1.0 or v.2.0 BeadChip. Analysis of expression data from stimulated monocytes, and epigenetic and chromatin interaction analyses were performed., Results: We identified 2 novel genetic susceptibility loci for Behçet's disease, including a risk locus in IFNGR1 (rs4896243) (odds ratio [OR] 1.25; P = 2.42 × 10
-9 ) and within the intergenic region LNCAROD/DKK1 (rs1660760) (OR 0.78; P = 2.75 × 10-8 ). The risk variants in IFNGR1 significantly increased IFNGR1 messenger RNA expression in lipopolysaccharide-stimulated monocytes. In addition, our results replicated the association (P < 5 × 10-8 ) of 6 previously identified susceptibility loci in Behçet's disease: IL10, IL23R, IL12A-AS1, CCR3, ADO, and LACC1, reinforcing the notion that these loci are strong genetic factors in Behçet's disease shared across ancestries. We also identified >30 genetic susceptibility loci with a suggestive level of association (P < 5 × 10-5 ), which will require replication. Finally, functional annotation of genetic susceptibility loci in Behçet's disease revealed their possible regulatory roles and suggested potential causal genes and molecular mechanisms that could be further investigated., Conclusion: We performed the largest genetic association study in Behçet's disease to date. Our findings reveal novel putative functional variants associated with the disease and replicate and extend the genetic associations in other loci across multiple ancestries., (© 2021, American College of Rheumatology.)- Published

- Abstract
Background: Acute appendicitis (AA) is the most common cause of surgery performed for the acute abdomen. The standard treatment for AA patients has been appendectomy for more than a century. The use of broad-spectrum antibiotics, the medical treatment option has come to the fore in the treatment of uncomplicated AA., Aim: Evaluate whether white blood cell (WBC), platelet count, mean platelet volume (MPV), platelet distribution width (PDW), red cell distribution width (RDW) and C-reactive protein (CRP) values of patients diagnosed with uncomplicated AA clinically, with laboratory tests and radiologically with abdominal computed tomography (CT) could be a marker for choosing medical or surgical treatment., Materials and Methods: 519 patients aged between 20 and 65 years who were diagnosed with uncomplicated AA by abdominal CT in our centre between January 2016 and January 2019 were retrospectively analysed. The presence of at least one of the criteria of 7 mm or more appendix diameter and oedema or fluid accumulation around the appendix was accepted as uncomplicated AA. After the diagnosis of AA, 223 patients were treated medically, while 296 patients underwent laparoscopic appendectomy. The first group included patients who were treated medically and the second group included patients who underwent laparoscopic appendectomy., Results: Group 2 patients had higher mean platelet count (P < .005) and RDW (P = .003) values compared to Group 1 patients, while mean PDW (P < .001) values were lower compared to those of Group 1 patients. The differences between the mean WBC, CRP and MPV values of the groups were not statistically significant (P > .05)., Conclusions: Recently, studies supporting antibiotic therapy have been conducted in patients diagnosed with AA. As a result, we think that PDW, RDW, and platelet values in patients diagnosed with uncomplicated AA may be a guide in choosing patients to be treated with surgery or antibiotics., (© 2021 John Wiley & Sons Ltd.)

- Abstract
Background: We investigated the prognostic usefulness of prechemoradiotherapy (CRT) albumin-to-alkaline phosphatase ratio (AAPR) in unresectable locally advanced pancreatic adenocarcinoma (LAPAC) patients managed with definitive concurrent CRT (CCRT)., Methods: A sum of 136 LAPAC patients who consecutively underwent definitive CCRT was retrospectively analyzed. The AAPR (serum albumin (g/dL)/serum alkaline phosphatase (IU/L)) was calculated by using the parameters obtained from the routine biochemistry tests on the first day of the CCRT. Ideal AAPR cutoff was sought by utilizing receiver operating characteristic (ROC) curve analysis. The primary and secondary endpoints were the impact of the AAPR on the overall survival (OS) and progression-free survival (PFS) results, respectively., Results: At a median follow-up of 14.8 months (range: 3.2-85.7), the median PFS and OS times were 7.5 (95% confidence interval (CI): 6.0-9.0) and 14.9 months (95% CI: 11.9-17.9), respectively. The ideal common AAPR cutoff was identified at the rounded 0.46 (area under the curve: 72.3%; sensitivity: 71.2%; specificity: 70.3%) point that dichotomized the patients into two groups: low AAPR (L-AAPR; N = 71) and high AAPR (H-AAPR; N = 65) groups, respectively. Comparative survival analyses showed that the L-AAPR cohort had significantly shorter median PFS (6.8 (95% CI: 5.7-7.9) versus 11.3 (95% CI: 9.9-12.7) months; P = 0.005) and OS (12.8 (95% CI: 10.6-15.0) versus 19.2 (95% CI: 16.9-21.5) months; P = 0.001) durations than their H-AAPR counterparts, separately. Albeit the N1-2 ( P = 0.004) and CA 19-9 > 90 U/mL ( P = 0.008) were also found to be associated with inferior outcomes, yet the results of the multivariate analyses ascertained the L-AAPR as an independent indicator of diminished PFS ( P = 0.003) and OS ( P = 0.002) results., Conclusion: The present results proposed that the pretreatment AAPR < 0.46 was a novel independent indicator of adverse PFS and OS in unresectable LAPAC patients undergoing definitive CCRT., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2021 Veysel Haksoyler and Erkan Topkan.)

- Abstract
Objectives: We endeavored to retrospectively assess the prognostic merit of pretreatment systemic immune response index (SIRI) in glioblastoma multiforme (GBM) patients who underwent postoperative partial brain radiotherapy (RT) and concurrent plus adjuvant temozolomide (TMZ), namely, the Stupp protocol., Methods: The records of 181 newly diagnosed GBM patients who received the postoperative Stupp protocol were retrospectively analyzed. The SIRI value for each eligible patient was calculated by utilizing the platelet, neutrophil, and lymphocyte measures obtained on the first day of treatment: SIRI = Neutrophils × Monocytes/Lymphocytes. The ideal cutoff values for SIRI connected with the progression-free- (PFS) and overall survival (OS) results were methodically searched through using the receiver operating characteristic (ROC) curve analysis. Primary and secondary end-points constituted the potential OS and PFS distinctions among the SIRI groups, respectively., Results: The ROC curve analysis labeled the ideal SIRI cutoffs at 1.74 (Area under the curve (AUC): 74.9%; sensitivity: 74.2%; specificity: 71.4%) and 1.78 (AUC: 73.6%; sensitivity: 73.1%; specificity: 70.8%) for PFS and OS status, individually. The SIRI cutoff of 1.78 of the OS status was chosen as the common cutoff for the stratification of the study population (Group 1: SIRI ≤ 1.78 ( N = 96) and SIRI > 1.78 ( N = 85)) and further comparative PFS and OS analyses. Comparisons between the two SIRI cohorts manifested that the SIRI ≤ 1.78 cohort had altogether significantly superior median PFS (16.2 versus 6.6 months; P < 0.001) and OS (22.9 versus 12.2 months; P < 0.001) than its SIRI > 1.78 counterparts. The results of multivariate Cox regression analyses ratified the independent and significant alliance between a low SIRI and longer PFS ( P < 0.001) and OS ( P < 0.001) durations, respectively., Conclusions: Present results firmly counseled the pretreatment SIRI as a novel, sound, and independent predictor of survival outcomes in newly diagnosed GBM patients intended to undergo postoperative Stupp protocol., Competing Interests: All authors declare that they have no conflicts of interest., (Copyright © 2020 Erkan Topkan et al.)

- Abstract
Objective: To determine the role of vascular endothelial growth factor (VEGF) in placental hypoperfusion in obesity., Methods: The prospective study enrolled women with a first-trimester singleton pregnancy in Izmir, Turkey, between January and April 2011. Participants were divided into three groups: obese (body mass index [BMI, calculated as weight in kilograms divided by the square of height in meters] >30) with cesarean delivery; normal weight (BMI <30) with vaginal delivery (NVD); and healthy controls (BMI <30) with cesarean delivery. Before delivery, serum C-reactive protein (CRP), and uterine and fetal Doppler measurements were taken. VEGF was evaluated immunohistochemically from the umbilical cord., Results: Overall, 109 women completed the study: obesity group (n=13, 11.9%), NVD group (n=50, 45.9%), and control group (n=46, 42.2%). Serum CRP was higher in the obesity group than in the control or NVD groups (P=0.009). VEGF score was highest in the NVD group (9.39 ± 3.11), and lowest in the obesity group (4.58 ± 2.78) (P<0.001). VEGF score decreased by 0.81 for each increase in BMI of 1 (P=0.002)., Conclusions: Maternal obesity was related to decreased VEGF expression. Although not supported by Doppler findings, decreased VEGF expression owing to maternal obesity might trigger endothelial dysfunction and inflammation., (© 2020 International Federation of Gynecology and Obstetrics.)

- Abstract
This study evaluated the long-term clinical outcomes of single-visit root canal treatments with apical enlargement on patients with necrotic pulp tissue retrospectively. A total of 137 teeth with necrotic pulp tissue which underwent single-visit root canal treatments were included. The root canals were shaped up until the apical constriction, which was determined by an apex locator. The outcomes were evaluated by two independent and calibrated endodontists clinically and radiographically. Teeth were dichotomized into healed (PAI ≤ 2, no signs or symptoms) and nonhealed (PAI > 2, with/without signs or symptoms) groups. Each patients' preoperative PAI and lesion size were recorded to evaluate the preoperative periapical status as well as several other prognostic factors. Statistical analyses were performed ( p = 0.05) on ninety teeth. The mean observation time was 60 months. Out of ninety teeth, 87 (96.7%) were healed and 3 (3.3%) were nonhealed. No correlations were found between the prognostic factors and the outcomes ( p > 0.05). Cohen's kappa and Gwet's agreement coefficient scores between the preoperative PAI scores and preoperative lesion sizes showed good agreements, with values of 0.834 and 0.898, respectively. Apical enlargement is a viable treatment option for single-visit root canal treatments., Competing Interests: The authors declare no conflict of interest regarding any of the materials used in this study., (Copyright © 2020 Tan F.

- Abstract
Objective: Sympathetic blocks are used as an adjunct for pain management in the treatment of orthopedic and traumatic conditions. Stellate ganglion (ganglion stellatum) provides sympathetic innervation of the head, neck and cervicothoracic regions, and upper extremities. No study was found in the literature investigating the effects of stellate ganglion block performed in the upper extremity, on blood supply to bone, density, vascularization, and bone metabolism. Therefore, the objective of this study was to investigate the effects of stellate ganglion block on healing of closed forearm fractures that were induced in rats. Material and Methods . A total of 42 Wistar albino rats weighing between 398 and 510 g were used in this study. The rats were randomly divided into 2 groups with one group treated with stellate ganglion and the other included as the control group. In each 2 groups, a closed forearm fracture was created, confirmed with X-ray, and then stabilized by splint application. The forearm bones were examined with X-ray views on the same day and were then decalcified., Results: When histological findings of the fracture region were examined, predominantly cartilage and less woven bone were found in 7 rats, equally distributed cartilage and immature bone in 14 rats, and predominantly imitation bone and less cartilage formation in 21 rats. In the control group, the agreement between the 1st and 2nd orthopedists for the radiological evaluation of bone formation was moderate., Conclusion: The group administered stellate ganglion block showed a more significant fracture healing., Competing Interests: The authors declare no conflict of interest regarding the present study., (Copyright © 2020 Hasan Kizilay et al.)

- Abstract
Background: We investigated the prognostic significance of pretreatment systemic inflammation response index (SIRI) in locally advanced pancreatic carcinoma (LAPC) patients treated with concurrent chemoradiotherapy (CRT)., Methods: Present retrospective cohort analysis investigated consecutive 154 LAPC patients who received radical CRT. The SIRI was defined as: SIRI = neutrophil × monocyte/lymphocyte counts. Ideal SIRI cutoff(s) influencing overall survival (OS) and progression-free survival (PFS) results were sought by using receiver operating characteristic (ROC) curve analysis. The primary endpoint was the interaction between the SIRI and OS results., Results: The median follow-up, PFS, and OS durations were 14.3 (range: 2.9-74.6), 7.9 [%95 confidence interval (CI): 5.7-10.1), and 14.7 months (%95 CI: 11.4-18.0) for the entire cohort, respectively. ROC curve analyses determined the ideal SIRI cutoff that exhibiting a significant link with OS and PFS outcomes at the rounded 1.6 point (AUC: 74.3%; sensitivity: 73.8%; specificity: 70.1%).The SIRI <1.6 patients ( N = 58) had significantly superior median PFS (13.8 versus 6.7 months; P < 0.001) and OS (28.6 versus 12.6 months; P < 0.001) lengths than SIRI ≥1.6 patients ( N = 96), respectively. Although the N0 (versus N1; P < 0.05) and CA 19-9 ≤90 U/mL (versus >90 U/mL) appeared as the other significant associates of better OS and PFS in univariate analyses, yet the results of multivariate analyses confirmed the SIRI <1.6 as the independent indicator of superior OS and PFS ( P < 0.001 for each)., Conclusion: Pretreatment SIRI is a novel independent prognosticator that may further enhance the conventional tumor-node-metastases staging system in a more precise prediction of the OS and PFS outcomes of LAPC patients after radical CRT., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2020 Erkan Topkan et al.)

- Abstract
Objectives: To evaluate the potential prognostic utility of pretreatment systemic immune-inflammation index (SII) in newly diagnosed glioblastoma multiforme (GBM) patients who underwent postneurosurgical radiotherapy and concurrent plus adjuvant temozolomide., Methods: The retrospective data of GBM patients who underwent postneurosurgical radiotherapy and concurrent plus adjuvant temozolomide were analyzed. For each patient, SII was calculated using the platelet, neutrophil, and lymphocyte measures obtained on the first day of treatment: SII = platelets × neutrophils/lymphocytes. The receiver operating characteristic (ROC) curve analysis was utilized for the evaluation of optimal cut-off values for SII those linked with the outcomes. Primary and secondary endpoints constituted the overall (OS) and progression-free survival (PFS) per conveyance SII group., Results: A total of 167 patients were included. The ROC curve analysis identified the optimum SII cut-off at a rounded 565 value that significantly interacted with the PFS and OS and stratified patients into two groups: low-SII (SII < 565; n = 71) and high-SII (SII ≥ 565; n = 96), respectively. Comparative survival analyses exhibited that the high-SII cohort had significantly shorter median PFS (6.0 versus 16.6 months; P < 0.001) and OS (11.1 versus 22.9 months; P < 0.001) than the low-SII cohort. The relationship between the high-SII and poorer PFS ( P < 0.001) and OS ( P < 0.001) further retained its independent significance in multivariate analysis, as well., Conclusions: The outcomes displayed here qualified the pretreatment SII as a novel independent prognostic index for predicting survival outcomes of newly diagnosed GBM patients undergoing postneurosurgical radiotherapy and concurrent plus adjuvant temozolomide., Competing Interests: None to declare with respect to the research, authorship, and/or publication of this article., (Copyright © 2020 Erkan Topkan et al.)

- Abstract
Objective: To compare the accuracy and reliability of the AmniSure, AMNIOQUICK, and AL-SENSE tests with conventional tests to diagnose suspected premature rupture of membranes (PROM)., Methods: A prospective cohort study of 60 pregnant women at 25-36 weeks of pregnancy with suspected PROM was conducted between January and April 2015. AmniSure (Qiagen Sciences LLC, Germantown, MD, USA), AMNIOQUICK (BIOSYNEX, Strasbourg, France), and AL-SENSE (Common Sense Ltd, Caesarea, Israel) tests were performed after conventional tests (ultrasonography, pooling, nitrazine, and fern tests) and women were followed-up for 7 days. Sensitivity, specificity, and diagnostic accuracy, among others, were assessed and compared., Results: For women with a confirmed diagnosis of PROM, the sensitivity and specificity of conventional tests were 93.7% and 100.0%, respectively; diagnostic accuracy was 98.3%. Sensitivity, specificity, and diagnostic accuracy were all 100.0% for AmniSure. Sensitivity, specificity, and diagnostic accuracy for AMNIOQUICK were 75.0%, 97.7%, and 91.6%, respectively. Sensitivity, specificity, and diagnostic accuracy were 75.0%, 86.3%, 83.3%, respectively, for the AL-SENSE pad test., Conclusion: The AmniSure test was most sensitive and specific for diagnosing PROM compared with the other tests and is reliable and usable., (© 2020 International Federation of Gynecology and Obstetrics.)

- Abstract
Objective: To compare volumetric arc therapy (VMAT) and helical tomotherapy (HT) plans in terms of dosimetric parameters in positron emission tomography- (PET-) computerized tomography- (CT-) based radiation therapy planning in unresectable malignant pleural mesothelioma (MPM)., Methods: CT and coregistered PET-CT data from seven patients with histologically-proven MPM were utilized for VMAT and HT plans. Target volumes and organs at risk (OARs) were delineated. The prescription doses for planning target volume 1 (PTV
1 ) and PTV2 were 45.0 Gy and 54 Gy in 1.8 Gy/fr, respectively. Each technique was evaluated in terms of target volume coverage and OAR doses., Findings: Although the maximum ( p =0.001) and mean ( p < 0.001) doses of PTV1 , and PTV2 ( p < 0.001 for maximum and p =0.001 for mean doses) favored the HT technique over VMAT, both techniques efficiently covered the target volumes. Additionally, HT also provided more homogeneous dose distribution ( p < 0.001) and numerically lower doses received by most OARs, but again both rotational techniques were successful in keeping the OAR doses below the universally accepted limits. The major disadvantage of the HT technique was the requirement for longer treatment times (7.4 versus 2.5 minutes/fr; p < 0.001) to accomplish the intended treatment., Conclusion: Results of this dosimetric comparison clearly demonstrated the possibility of safe hemithoracic irradiation of medically/technically unresectable MPM patients with either of the two rotational RT techniques, namely the VMAT and HT. Clinically, considering their poor prognosis, these promising findings may open a potential new window for curative treatment of unresectable MPM patients, if further confirmed by future clinical studies., Competing Interests: The authors declare that they have no conflicts of interest., (Copyright © 2019 Berrin Pehlivan et al.)- Published

- Abstract
The clinical impact and accessibility of
99m Tc tracers for cancer diagnosis would be greatly enhanced by the availability of a new, simple, and easy labeling process and radiopharmaceuticals. 5-Fluorouracil is an antitumor drug, which has played an important role for the treatment of breast carcinoma. In the present study, a new derivative of 5-Fluorouracil was synthesized as (1-[{1'-(1''-deoxy-2'',3'':4'',5''-di-O-isopropylidene-β-D-fructopyranose-1''-yl)-1'H-1',2', 3'-triazol-4'-yl}methyl]-5-fluorouracil) (E) and radiolabeled with99m Tc. It was analyzed by radio thin layer chromatography for quality control and stability. The radiolabeled complex was subjected to in vitro cell-binding studies to determine healthy and cancer cell affinity using HaCaT and MCF-7 cells, respectively. In addition, in vitro cytotoxicity studies of compound E were performed with HaCaT and MCF-5 cells. The radiochemical purity of the [99m Tc]TcE was found to be higher than 90% at room temperature up to 6 hours. The radiolabeled complex showed higher specific binding to MCF-7 cells than HaCaT cells. IC50 values of E were found 31.5 ± 3.4 μM and 20.7 ± 2.77 μM for MCF-7 and HaCaT cells, respectively. The results demonstrated the potential of a new radiolabeled E with99m Tc has selective for breast cancer cells., (© 2019 John Wiley & Sons, Ltd.)- Published

- Abstract
This study evaluated the potential of three essential oils (EOs) that were obtained from coriander Coriandrum sativum (CEO), linaloe tree Bursera delpechiana (BEO), and lavender Lavandula hybrida (LEO) as anesthetic agents. Convict Cichlids Amatitlania nigrofasciata (Günther 1867) were exposed to eight concentrations of anesthetic (50, 75, 100, 125, 150, 200, 250, and 300 μL/L). After exposure to the anesthetic, the fish were transferred to clean water to recover. All of the EOs produced an anesthetic effect after exposure to the compounds for 30 min at the minimal effective concentration (MEC), which was identified according to deep anesthesia (A
5 < 3 min) and full recovery (R3 < 5 min) times. At 50 and 75 μL/L, the total loss of equilibrium was not observed for all tested EOs. The total loss of reflex was induced at a faster rate with higher concentrations of anesthetic in all groups. The recovery time generally increased as the concentration of the anesthetic increased. These findings suggest that CEO, BEO, and LEO are all novel potential anesthetics for aquaculture, and the optimal concentrations were identified as 150 μL/L (A5 ; 156 ± 1.7 s and R3 ; 165 ± 2.9 s), 125 μL/L (A5 ; 176 ± 3.5 s; R3 ; 125 ± 2.0 s), and 200 μL/L (A5 ; 20.1 ± 2.4 s and R3 ; 162 ± 3.4 s), respectively. When considering the active ingredients of EOs, this study also demonstrated that future studies should be focused on the major components such as linalyl acetate, 1.8-cineole, α-pinene, geraniol, and linalool. Their synergistic effects should be examined in herbal anesthetic treatments, since new commercial anesthetics will likely contain them., (© 2019 American Fisheries Society.)- Published

- Abstract
Recent randomized trials have shown that completion axillary lymph node dissection (ALND) is not required in all patients with a positive sentinel lymph node (SLN) who will receive radiation therapy. Although routine intraoperative pathologic assessment (IPA) becomes unnecessary and less indicated by breast surgeons in the United States and some European countries, it is still widely used all around the world. In this prospective study, the feasibility of intraoperative nodal palpation (INP) as opposed to IPA of the SLN has been analyzed. Between March 2014 and June 2015, 305 patients with clinical T1-2/N0 breast cancer from two different breast clinics (cohort A; [n = 225] and cohort B; [n = 80]) who underwent any breast surgery with sentinel lymph node biopsy (SLNB) were included in this study. Surgeons evaluated the SLNs by manual palpation before sending for IPA, and findings compared with the final pathology. The positive predictive values (PPV) of INP and IPA were 81.8% and 97.9%, respectively, whereas the negative predictive values (NPV) of INP and IPA were 83% and 92.4%. The accuracies of INP and IPA were 82.6% and 94.1%, respectively. If patients with SLNB including micrometastasis were also considered in the final pathologic assessment (FPA) (-) group that would not require a further axillary dissection, the revised NPV of INP and FPA were found to be 92.6% and 98.1%, respectively. The revised accuracy of INP also found to be increase to 86.9%. Our study, which is the only prospective one about palpation of dissected SLNs in the literature, suggests that INP can help to identify patients who do not need ALND, which encourages omitting IPA in cT1-2 N0 breast cancer., (© 2018 Wiley Periodicals, Inc.)

- Abstract
Backgrounds: Pilonidal sinus is a common chronic disease of the sacrococcygeal region. Although many surgical methods have been described for treating pilonidal sinus disease, controversy still exists as to the best surgical technique. The aim of this study is to present a new modified advancement flap technique named "omega flap" for the treatment of pilonidal sinus disease., Materials and Methods: This study included 18 patients with pilonidal sinus who were treated between March 2012 and August 2014. All cases underwent oval excision and omega advancement flap reconstruction. Defect size, postoperative complications, postoperative pain, painless sitting time, patient satisfaction and recurrence were evaluated retrospectively., Results: All patients were discharged on the first postoperative day. There was no flap necrosis. No recurrence and no major complication were observed during follow-up period. The outcomes were also satisfactory regarding functionally and aesthetically, and the patients were satisfied with the results., Conclusions: Presented method has a different geometry than classical advancement flap methods. Our technique provides two-layered repair with minimal tension and off-midline closure for the reconstruction of pilonidal sinus defect. It is easily performed, reliable, associated with no recurrens and good aesthetic results.

- Abstract
Background: Incidence of mycobacterial infections has been increasing. However, diagnosis and treatment of mycobacterial infections can be difficult. The aim of this study was to investigate high-performance liquid chromatography (HPLC) analysis of the mycolic acids for rapid identification and dendrogram cluster analysis of mycobacterium species., Methods: Clinical specimens received for mycobacterial culture and antimicrobial susceptibility test were processed by standard laboratory protocols. Positive cultures were analyzed with HPLC method. Mycolic acid analysis with HPLC was used for diagnosis of tuberculosis and other mycobacterial infections. These reports were compared with Sherlock Library mycobacterial species, and the similarity index was analyzed. This value was formed by a software in multidimensional space that was the calculation of the average distance between the nearest library profile and unknown profile., Results: The ninety-two samples were identified as M. tuberculosis. (similarity index between 0.593 and 0.994). One of the other strains was identified as M. avium intracellulare (strain No. 82) (SI = 0.906); one of them was identified as M. interjectum (strain no. 89) (SI = 0.644). Total 94 samples were identified, and dendrogram was applied to these samples. Profile A (10.6%), profile B (59.6%), profile C (11.7%), profile D (3.2%), and other profiles as single different profiles were identified. Rates for each as 1% (89, 94, 1, 82, 26, 42, 32, 41, 100, 43, 47, 44, 40, 35)., Conclusion: High-performance liquid chromatography is a useful, rapid, reliable, and practical method for diagnosis of mycobacterium species., (© 2018 Wiley Periodicals, Inc.)

- Abstract
Hydrogen bonding and π-π interactions take special part in the enantioselectivity task. In this regard, because of having both hydrogen acceptor and hydrogen donor groups, melamine derivatives become more of an issue for enantioselectivity. In the light of such information, triazine-based chiral, fluorescence active novel thiazole derivatives L1 and L2 were designed and synthesized from (S)-(-)-2-amino-1-butanol and (1S,2R)-(+)-2-amino-1,2-diphenylethanol. The structural establishment of these compounds was made by spectroscopic methods such as FTIR,
1 H, and13 C NMR. While the solution of these compounds in DMSO did not show any fluorescence emission, it was observed that the emission increased 44-fold for L1 and 55-fold for L2 in 95% water, similar to the aggregation-induced emission (AIE) characterized compounds. In this regard, enantioselective capabilities of these compounds against carboxylic acids were tested, and in experiments carried out at a ratio of 40/60 DMSO/H2 O, it was determined that R-2ClMA increased the fluorescence emission of L1 chiral receptor by 2.59 times compared to S-isomer., (© 2017 Wiley Periodicals, Inc.)- Published

- Abstract
Objective: To prepare a dermatologic addendum to the 2012 revised International Chapel Hill Consensus Conference Nomenclature of Vasculitides (CHCC2012) to address vasculitides affecting the skin (D-CHCC). The goal was to standardize the names and definitions for cutaneous vasculitis., Methods: A nominal group technique with a facilitator was used to reach consensus on the D-CHCC nomenclature, using multiple face-to-face meetings, e-mail discussions, and teleconferences., Results: Standardized names, definitions, and descriptions were adopted for cutaneous components of systemic vasculitides (e.g., cutaneous IgA vasculitis as a component of systemic IgA vasculitis), skin-limited variants of systemic vasculitides (e.g., skin-limited IgA vasculitis, drug-induced skin-limited antineutrophil cytoplasmic antibody-associated vasculitis), and cutaneous single-organ vasculitides that have no systemic counterparts (e.g., nodular vasculitis). Cutaneous vasculitides that were not included in the CHCC2012 nomenclature were introduced., Conclusion: Standardized names and definitions are a prerequisite for developing validated classification and diagnostic criteria for cutaneous vasculitis. Accurate identification of specifically defined variants of systemic and skin-limited vasculitides requires knowledgeable integration of data from clinical, laboratory, and pathologic studies. This proposed nomenclature of vasculitides affecting the skin, the D-CHCC, provides a standard framework both for clinicians and for investigators., (© 2017, American College of Rheumatology.)

- Abstract
Background: Liver biopsy is recommended in the majority of patients with chronic viral hepatitis for fibrosis evaluation. Because of the potential risks of liver biopsy, many studies related to non-invasive biomarkers of hepatic fibrosis have been performed. We aimed to assess the diagnostic value of serum biglycan as a non-invasive fibrosis marker in chronic hepatitis B patients., Methods: This study included 120 patients with biopsy-proven hepatitis B patients and 60 healthy controls. Fibrosis stage and necroinflammatory activity were assessed in liver biopsy specimens. Biglycan level was measured using an ELISA assay., Results: Serum biglycan levels of chronic hepatitis B patients were found to be significantly higher than those of healthy controls (337.3±363.0 pg/mL vs 189.1±61.9 pg/mL, respectively, P<.001). There was a statistically significant positive correlation between serum biglycan level and fibrosis stage (P=.004; r=.213). Besides, a statistically significant positive correlation was found between serum biglycan level and necroinflammatory activity (P<.001; r=.271). The AUROC of BGN levels was 0.702 for fibrosis stage, differentiating patients from healthy controls with statistical significance (P<.001). The AUROC of BGN levels was 0.632 for necroinflammatory activity score, differentiating patients from healthy controls with statistical significance (P=.004)., Conclusions: Serum biglycan might be used as a non-invasive marker of liver fibrosis. Further studies are needed to evaluate the usefulness of this marker., (© 2016 Wiley Periodicals, Inc.)

- Abstract
Objective: To identify a genetic cause of early-onset systemic lupus erythematosus (SLE) in a large consanguineous family from Turkey and to study the mechanisms of the disease., Methods: We performed whole-exome sequencing and single-nucleotide polymorphism array genotyping in family members with and without SLE. Protein and gene expression, cytokine profile, neutrophil extracellular trap (NET) formation, and presence of low-density granulocytes were evaluated in patient primary cells and serum samples., Results: We identified a novel, homozygous, loss-of-function mutation (p.Pro445Leufs*11) in the C1R gene. Using the Sanger method of DNA sequencing in 14 family members, we confirmed the presence of the mutation in 4 patients with SLE and in an asymptomatic 9-year-old girl. Complement levels were low in sera from patients with truncated C1r protein. Two siblings with SLE who were available for detailed evaluation exhibited strong type I interferon (IFN) inflammatory signatures despite their disease being clinically inactive at the time of sampling. The type I IFN transcriptional signature in the patients' blood correlated with disease expressivity, whereas the neutrophil signature in peripheral blood mononuclear cells was likely associated with disease severity. The female patient with SLE with the most severe phenotype presented with a stronger neutrophil signature, defined by enhanced NET formation and the presence of low-density granulocytes. Analysis of exome data for modifying alleles suggested enrichment of common SLE-associated variants in the more severely affected patients. Lupus-associated HLA alleles or HLA haplotypes were not shared among the 4 affected subjects., Conclusion: Our findings revealed a novel high-penetrance mutation in C1R as the cause of monogenic SLE. Disease expressivity in this family appears to be influenced by additional common and rare genetic variants., (© 2017, American College of Rheumatology.)

- Abstract
Objective: The objective was to compare the protective effects of N-acetylcysteine (NAC) plus normal saline (NS), sodium bicarbonate (NaHCO
3 ) plus NS, and NS alone in the prevention of contrast-induced nephropathy (CIN) after computed tomography pulmonary angiography (CTPA) in emergency patients., Methods: This study was planned as a randomized, controlled clinical research. Patients undergoing contrast-enhanced CTPA on suspicion of pulmonary embolism (PE) in the emergency department and with at least one risk factor for development of CIN were included in one of three different prophylaxis groups. The groups received 3 mL/kg intravenous (IV) NAC+NS or NaHCO3 +NS solution or NS alone 1 hour before CTPA and 1 mL/kg IV per hour for a minimum of 6 hours after CTPA. CIN was evaluated as the primary outcome and moderate or severe renal insufficiency and in-hospital mortality as secondary outcomes., Results: A total of 257 patients were enrolled in the study. The total level of CIN development was 23.7% (61/257), the level of moderate and severe renal failure was 12.5% (32/257), and the in-hospital mortality rate was 12.8% (33/257). Rates of CIN development in the drug groups were 23.5% in the NAC group (20/85), 21.2% (18/85) in the NaHCO3 group, and 26.4% in the NS group (23/87). Rates of development of moderate or severe renal insufficiency were 9.4% in the NAC group (8/85), 10.6% in the NaHCO3 group (9/85), and 17.2% in the NS group (15/87). In-hospital mortality rates were 12.9% in the NAC group (11/85), 11.8% in the NaHCO3 group (10/85), and 13.8% in the NS group (12/87). No difference was determined between the drug groups in terms of CIN, moderate or severe renal injury, or hospital mortality., Conclusions: Our results indicate that there is a high risk of CIN in patients with suspected PE despite three different types of prophylaxis being administered, and no statistically significant differences were observed among prophylactic NAC, NaHCO3 , and NS in prevention of CIN following contrast-enhanced CTPA., (© 2016 by the Society for Academic Emergency Medicine.)- Published

- Abstract
Objective: To estimate the placebo effect in juvenile idiopathic arthritis (JIA) through a meta-analysis of phase III clinical trials with placebo comparator., Methods: A systematic literature search was carried out up to December 2014. For parallel design studies the outcome was evaluated as a single 1-dimensional (1-D) variable or as a composite score; outcomes of withdrawal studies were evaluated only as composite scores., Results: We included 26 of 224 trials (12%). In trials with parallel study design and a 1-D outcome, the placebo effect was 0.35 (95% confidence interval [95% CI] 0.27-0.43). Among trials with parallel study design and a composite score outcome, the placebo rate response was higher in trials that included patients with nonsystemic JIA (0.35 [95% CI 0.29-0.42]) than in trials that included only patients with systemic JIA (0.17 [95% CI 0.10-0.30]). In the withdrawal design trials, the percentages of patients receiving placebo who had disease flares during the double-blind phase were lower in trials that included patients with nonsystemic JIA (0.55 [95% CI 0.47-0.64]) than in trials that included only patients with systemic JIA (0.68 [95% CI 0.33-0.90])., Conclusion: In trials with a parallel study design a sizable number of patients seem to benefit from a placebo effect, although this effect is smaller in patients with systemic JIA. In trials with a withdrawal design the inverse placebo effect is similar among the different JIA categories. This placebo effect should be considered when evaluating the effectiveness of proposed interventions and for future calculations of sample size., (© 2016, American College of Rheumatology.)

- Abstract
Objective: To develop criteria for the classification of macrophage activation syndrome (MAS) in patients with systemic juvenile idiopathic arthritis (JIA)., Methods: A multistep process, based on a combination of expert consensus and analysis of real patient data, was conducted. A panel of 28 experts was first asked to classify 428 patient profiles as having or not having MAS, based on clinical and laboratory features at the time of disease onset. The 428 profiles comprised 161 patients with systemic JIA-associated MAS and 267 patients with a condition that could potentially be confused with MAS (active systemic JIA without evidence of MAS, or systemic infection). Next, the ability of candidate criteria to classify individual patients as having MAS or not having MAS was assessed by evaluating the agreement between the classification yielded using the criteria and the consensus classification of the experts. The final criteria were selected in a consensus conference., Results: Experts achieved consensus on the classification of 391 of the 428 patient profiles (91.4%). A total of 982 candidate criteria were tested statistically. The 37 best-performing criteria and 8 criteria obtained from the literature were evaluated at the consensus conference. During the conference, 82% consensus among experts was reached on the final MAS classification criteria. In validation analyses, these criteria had a sensitivity of 0.73 and a specificity of 0.99. Agreement between the classification (MAS or not MAS) obtained using the criteria and the original diagnosis made by the treating physician was high (κ = 0.76)., Conclusion: We have developed a set of classification criteria for MAS complicating systemic JIA and provided preliminary evidence of its validity. Use of these criteria will potentially improve understanding of MAS in systemic JIA and enhance efforts to discover effective therapies, by ensuring appropriate patient enrollment in studies., (© 2015, American College of Rheumatology.)

- Abstract
A 79-year-old woman was admitted to our emergency department with complaints of fainting and loss of consciousness three times during the past month. She was diagnosed with epilepsy and started to be treated with antiepileptic drug. Physical examination showed, in the left eye, chemosis, limited eye movements in all directions, and minimal exophthalmos as unexisting symptoms on admission developed on the sixth day. Orbital magnetic resonance imaging (MRI) and digital subtraction angiography (DSA) imaging revealed a carotid cavernous fistula (CCF). Epileptic attacks and ophthalmic findings previously present but diagnosed during our examinations were determined to ameliorate completely after performing the coil embolization. Based on literature, we present the first case with nontraumatic CCF manifesting with epileptic seizures and intermittent eye symptoms in the present report., Competing Interests: The authors declare that there is no conflict of interests regarding the publication of this report.

- Abstract
Introduction. Short bowel syndrome can crop up if more than 50% of small intestine is resected or when less than 100 cm of small bowel is left. Glutamine is the main food source of enterocytes. Curcumin has protective effects on intestinal ischemia-reperfusion damage. Nesfatin-1 is a satiety molecule. It has protective effects on gastric mucosa. The primary purpose of this study is to compare effects of glutamine, curcumin, and nesfatin-1 on the gastric serosal surface neomucosa formation on rats. Materials and Methods. 24 Wistar-Hannover rats were randomly divided into 4 groups and treated with saline, glutamine, curcumin, and nesfatin-1 after ileogastric anastomosis. After 14 days all rats were euthanized, and blood was collected. En bloc resection of anastomotic part was performed for histopathological examination. Results. PDGF, TGF-β, and VEGF levels and neomucosa formation were higher in glutamine group (p = 0.003, p = 0.003, and p = 0.025). Glutamine promotes the intestinal neomucosa formation on the gastric serosal surface and augments growth factors essential for neomucosa formation on rats. Conclusion. Glutamine may be used in short bowel syndrome for increasing the absorption surface area. But that needs to be determined by adequately powered clinical trials.

- Abstract
Purpose: The aim of this prospective study was to determine the efficacy of intraarticular levobupivacaine with and without intravenous dexketoprofen trometamol for postarthroscopy analgesia., Methods: Sixty patients who underwent arthroscopic knee surgery were randomly assigned to three treatment groups. When the surgical procedure was completed, patients received the following treatments: group I (n = 20) patients received 20 mL intraarticular normal saline and 2 mL intravenous dexketoprofen trometamol (50 mg); group II (n = 20) patients received 20 mL intraarticular 0.5 % levobupivacaine (100 mg) and 2 mL intravenous normal saline; and group III (n = 20) patients received 20 mL intraarticular 0.5 % levobupivacaine (100 mg) and 2 mL intravenous dexketoprofen trometamol (50 mg). The visual analogue scale (VAS) was used, and the total analgesic consumption was assessed at 1, 2, 4, 6, 12, and 24 h post-operatively., Results: The VAS scores at 1, 2, 4, 6, 12, and 24 h post-operatively were significantly increased in group I and group II compared with group III (p < 0.05). The average VAS score during the first 24 h post-operatively was significantly lower in group III than in group I and group II (p < 0.001). Total meperidine consumption was significantly lower in group III than in groups I and II (p < 0.001)., Conclusion: Intraarticular levobupivacaine with adjuvant intravenous dexketoprofen trometamol administration provided better pain relief and less analgesic requirement after arthroscopic knee surgery during the first 24 h than that induced by dexketoprofen alone or levobupivacaine intraarticular alone., Level of Evidence: II.

- Abstract
Objective: To compare ultrasound measurements and clinical assessments of cervical dilatation, fetal head station and fetal head position., Design: Prospective, observational study., Setting: Tertiary care center (Ankara University Hospital), labor ward., Population: Forty-three women in labor., Methods: Women were prospectively evaluated through simultaneous examinations (79 in total). Dilatation, head station, and position were recorded via digital examination whenever possible and were compared with ultrasonographic measurements of dilatation, angle of progression, head-perineum distance, and head position by two independent operators. Operators were blinded to each other's findings., Main Outcome Measures: Agreement between sonographic measurements and digital examinations., Results: Ultrasonographic assessment of dilatation correlated significantly with digital examination. The interclass correlation coefficient of the two methods was 0.82 (95% confidence interval 0.73-0.88). Ultrasonography showed a mean lower cervical dilatation of 10 mm (95% limits of agreement: -36 to 16 mm) compared with digital examination. The angle of progression and head-perineum distances correlated moderately with the palpated head station (Pearson's correlation coefficients: 0.55 and -0.42, respectively; p < 0.001). Position could only be assessed in 40 of 79 examinations by digital examinations and the results showed low agreement with ultrasound findings., Conclusion: We observed good agreement between clinical and ultrasound assessment of dilatation, moderate agreement in assessing fetal station and low agreement assessing head position., (© 2015 Nordic Federation of Societies of Obstetrics and Gynecology.)

- Abstract
Introduction: Using single anesthetic agent in endoscopic retrograde cholangiopancreatography (ERCP) may lead to inadequate analgesia and sedation. To achieve the adequate analgesia and sedation the single anesthetic agent doses must be increased which causes undesirable side effects. For avoiding high doses of single anesthetic agent nowadays combination with sedative agents is mostly a choice for analgesia and sedation for ERCP., Aim: The aim of this study is to investigate the effects of propofol alone, propofol + remifentanil, and propofol + fentanyl combinations on the total dose of propofol to be administered during ERCP and on the pain scores after the process., Materials and Method: This randomized study was performed with 90 patients (ASA I-II-III) ranging between 18 and 70 years of age who underwent sedation/analgesia for elective ERCP. The patients were administered only propofol (1.5 mg/kg) in Group Ι, remifentanil (0.05 μg/kg) + propofol (1.5 mg/kg) combination in Group II, and fentanyl (1 μg/kg) + propofol (1.5 mg/kg) combination in Group III. All the patients' sedation levels were assessed with the Ramsey Sedation Scale (RSS). Their recovery was assessed with the Aldrete and Numerical Rating Scale Score (NRS) at 10 min intervals., Results: The total doses of propofol administered to the patients in the three groups in this study were as follows: 375 mg in Group I, 150 mg in Group II, and 245 mg in Group III., Conclusion: It was observed that, in the patients undergoing ERCP, administration of propofol in combination with an opioid provided effective and reliable sedation, reduced the total dose of propofol, increased the practitioner satisfaction, decreased the pain level, and provided hemodynamic stability compared to the administration of propofol alone.
