Abstract
Allergy is a systemic inflammation; therefore, although the allergic symptom may be seen in a specific organ system, the effects of this inflammation may be seen in other organs. interleukin (IL) IL4, IL5 and IL13 are the major Th2 cytokines and e-cadherin is an epithelial barrier protein. The objective of this research was to assess indicators of inflammation specific to Th2 responses and proteins related to the protective barrier of the airway's inner lining. These assessments were conducted using exhaled breath condensate (EBC), which provides insights into peripheral airway conditions of children suffering from food allergies. The study had 24 patients with food allergy and 24 control individuals younger than three years of age with no history of food reaction. The diagnosis of food allergy was based on food allergen-specific IgE and skin prick test positivity in our clinic and oral food testing in selected cases. EBC samples were obtained by Ecoscreen (Jaegar, Hoechberg, Germany). IL4, IL5, IL13 and E-cadherin levels were measured in these samples by enzyme linked immunoassay. The group of children with food allergies, consisting mainly of 14 girls, had a median age of 16 months, whereas the control group, which included 11 girls, had a median age of 15 months (p= 0.89). Comparing the two groups, children with food allergies exhibited notably lower levels of IL-13 in the EBC compared to the control group (median values of 59.14 and 76.36, respectively,p= 0.02). Conversely, the concentration of IL-4 in the EBC was significantly higher in children with food allergies (median values of 1.94 and 1.29, respectively,p= 0.003). However, the levels of IL-5 and e-cadherin showed no significant differences between the two groups (withp-values of 0.74 and 0.09, respectively) as shown in table1. High level of IL-4 despite the low level of IL-13 in the EBC of children having food allergy may be indicative of an early inflammatory phase that is not yet in the effector phase. Studies about the evolution of this process later in life are needed to assess the role of airway inflammation in children with food allergy who develop asthma.

Abstract
Background The American Thoracic Society (ATS) Methods in Epidemiologic, Clinical, and Operations Research (MECOR) Program aims to build research capacity in low and middle-income countries. MECOR has three levels, during which students learn to develop a research protocol and write a manuscript. MECOR Turkiye has been offered every year since 2008. Objective The aim of this paper is to report the number and impact of published articles generated from research questions developed by students in levels 1, 2, and 3 of the ATS MECOR Program in Turkiye between 2008 and 2018. Methods We collected the research questions developed in all levels of the ATS MECOR Program in Turkiye between 2008 and 2018. We searched Google Scholar, PubMed, Web of Science, and ResearchGate in April 2022 to see how many of these research questions were published as articles and, if published, in which journals. Results Of the 176 research questions collected, 49 had been developed in level 1, 82 had been developed in level 2, and 45 had been developed in level 3. Of those 176 research questions, 55 (31.3%) generated articles that were accepted for publication. The frequency of published articles based on MECOR-developed research questions increased linearly as the course level in which they were developed increased (18.4% in level 1, 30% in level 2, 46.7% in level 3; P = 0.012; linear-by-linear association, P = 0.003). The median time from the development of the research question to publication was three years overall and did not differ significantly among the course levels (P = 0.36). Of the research questions developed, 43 were published in Science Citation Index or Science Citation Index Expanded-indexed journals. Conclusion Acceptance of an article for publication is one way to measure the impact of the ATS MECOR Program. Our data describe significant research output among our participants, which increases with their length of participation in the program.

Abstract
OBJECTIVE There are limited data on nutritional management of infants with intrauterine growth restriction (IUGR). Postnatal protein supplementation for promoting growth is a common clinical practice in neonatology. The present study aims to investigate the consequences of protein supplementation on long-term growth, brain and body weight, brain histology and behavioral outcome in a rat model of IUGR. MATERIALS AND METHODS Twenty-four IUGR-formed rat puppies and 12 healthy puppies were included in the study. IUGR model was established by low (10%) protein diet throughout pregnancy together with intraperitoneal injection of lipopolysaccharide (LPS). Pups were started to be fed with either standard protein (SP), or high protein (HP) diet until postnatal day (PN) 35. Puppies in the control group were given SP diet for 35 days. Six pups from each group were sacrificed at PN7, remaining six were evaluated by Morris water maze test between PN 30 to 35 days and then sacrificed at PN35. Histologic evaluation of brain tissue was performed at PN7 and PN35. RESULTS IUGR group displayed lower body and brain weights at PN7 when compared with control. At PN35, SP group achieved similar brain/body weight ratios with control, whereas HP group displayed lowest brain/body weight ratio. The number of TUNEL positive cells was significantly higher and myelin basic protein and oligodendrocyte marker O4 immunoreactivity were significantly lower in HP group when compared with SP at PN35. Neuronal density in prefrontal cortex and hippocampus at PN7 were similar among SP and HP groups, but significantly lower in HP group when compared with SP at PN35. SP group displayed better results in the Morris water maze test when compared with HP group. CONCLUSIONS Although postnatal HP support is associated with increase in body weight at PN35, it did not result in better brain/body weight ratios in the rat model of IUGR. In IUGR rats, HP diet was associated with increased apoptosis in brain tissue with lower neuronal density and decreased myelination when compared to SP. Furthermore, better neurodevelopmental scores were achieved by SP diet rather than HP support in IUGR.

Abstract
OBJECTIVE The clinical symptoms in benign prostatic hyperplasia (BPH) are directly proportional to prostate volume. We aimed to show whom and when to intervene in a noninvasive way, correlating the patient's subjective symptoms with objective diagnostic tools. MATERIAL AND METHOD International Prostate Symptom Score (IPSS) was evaluated in patients who consulted the urology outpatient clinic for the first time with lower urinary tract symptoms (LUTS). Subsequently, PSA, urea, creatinine, complete urinalysis, uroflowmetry, urinary tract ultrasound and non-contrast lower abdominal computed tomography (CT) examinations were requested. Prostate central (transitional zone) zone and peripheral zone HU scores, prostatic urethral length and bladder wall Hounsfield units (HU) scores were recorded by using computed tomography (CT). The ellipsoid formula was used for ultrasonographic and tomographic measurements of prostate size (anteroposterior diameter × transverse diameter × longitudinal diameter × 0.52). RESULTS A statistically significant negative correlation was found between the prostate peripheral zone/central zone HU ratio and the maximum flow rate measured in the uroflowmetry test. CONCLUSION This is the first study in the literature to evaluate the correlation between voiding parameters such as Qmax, Qave and IPSS scores, and prostate and bladder wall HU scores obtained by computed tomography examination in BPH patients. A significant relationship has been detected between the peripheral zone/central zone HU ratio and Q max. Additional studies with larger patient populations could better clarify the contribution of HU in the diagnosis of BPH and treatment decision making of these patients.

Abstract
ABSTRACT A 20-year-old Arabian mare, was brought to the obstetrics and gynecology clinic with the complaint of an unknown wound in the genital area. Although the mare's general condition was good, examination of the genital area revealed a wide-open wound in the vulva and posterior vagina, characterized by fibrotic growth. The biopsy sample was sent to the pathology laboratory. A diagnosis of squamous cell carcinoma (SCC) was made after histopathological examination. Blood samples for serum biochemistry and hematological tests were collected from the jugular vein. Hematological and serum biochemical findings are generally used to diagnose diseases in animals and humans. Hematological and serum biochemical findings are important with genital SCC. Therefore, the findings of these values are given in this case report.

Abstract
Fetal programming is a mechanism whereby stimuli acting on the developing fetus influence the development of the fetus in a way that may set the stage for adult health and disease. These stimuli may be environmental, such as maternal smoking; metabolic, such as the maternal diet and nutrition; or endocrine, such as diabetes or stress, and may extend over several generations. The endocrine system influences fetal programming with effects of insulin, thyroid hormones, and glucocorticoid hormones. Epigenetic information may be modified by DNA methylation, histone modifications, and micro RNAs due to environmental exposures. In this review, we describe the normal development of the lungs and the major factors that may influence lung growth and development with the potential for sequelae into adult life.

Abstract
While breathing, many microorganisms, harmful environmental particles, allergens, and environmental pollutants enter the human airways. The human respiratory tract is lined with epithelial cells that act as a functional barrier to these harmful factors and provide homeostasis between external and internal environment. Intercellular epithelial junctional proteins play a role in the formation of the barrier. E-cadherin is a calcium-dependent adhesion molecule and one of the most important molecules involved in intercellular epithelial barier formation. E-cadherin is not only physical barrier element but also regulates cell proliferation, differentiation and the immune response to environmental noxious agents through various transcription factors. In this study, we aimed to review the role of E-cadherin in the formation of airway epithelial barier, its status as a result of exposure to various environmental triggers, and respiratory diseases associated with its dysfunction. Moreover, the situations in which its abnormal activation can be noxious would be discussed.

Abstract
West Nile virus (WNV) is a mosquito-borne virus of a re-emergence importance with a wide range of vertebrate hosts. Granted, it causes asymptomatic infection, but fatal cases and neurologic disorders were also recorded, especially in humans, horses and some exposed birds. The virus is globally spread and birds are considered an amplifying and reservoir host of WNV, helping to spread the disease due to their close contact with main hosts. In this study, we aimed to detect the presence of antibodies against WNV in backyard hens that were reared in the western Anatolian part of Turkey. A total of 480 chicken sera were randomly collected from six provinces in the west of Turkey (Mugla, Izmir, Aydin, Afyonkarahisar, Kutahya and Manisa) with 80 samples from each province (40 in spring and 40 in fall seasons). They were tested by using a competitive ELISA method to identify the specific avian antibodies of IgG that produced against the WNV envelope proteins (pr-E). Twelve of 480 (2.5%) sera were found seropositive, three of these positive sera were detected from the Izmir province (3.75%) collected in the spring session and the other nine positive sera were detected from the Mugla province (11.25%) collected in the fall session. Both of these provinces are located seaside and have suitable climate conditions for vectors of infection. The results indicated that WNV infection is in circulation in these provinces, and that may put the other susceptible vertebrates under risk of infection.

Abstract
BACKGROUND Palmoplantar pustulosis (PPP) is a rare, chronic, inflammatory skin disease characterized by sterile pustules on palmar or plantar areas. Data on PPP are scarce. AIM To investigate the clinical characteristics and risk factors for disease severity in a large cohort of Turkish patients with PPP. METHODS We conducted a cross-sectional, multicentre study of patients with PPP recruited from 21 tertiary centres across Turkey. RESULTS In total, 263 patients (165 women, 98 men) were evaluated. Most patients (75.6%) were former or current smokers. The mean Palmoplantar Pustulosis Area and Severity Index (PPPASI) was 8.70 ± 8.06 and the mean Dermatology Life Quality Index (DLQI) score was 6.87 ± 6.08, and these scores were significantly correlated (r = 0.52, P < 0.001). Regression analysis showed that current smoking was significantly associated with increased PPPASI (P = 0.03). Coexisting psoriasis vulgaris (PsV) was reported by 70 (26.6%) patients. Male sex prevalence, PPP onset incidence, disease duration, DLQI, and prevalence of nail involvement and psoriatic arthritis (PsA) were significantly increased among patients with PPP with PsV. Of the 263 patients, 18 (6.8%) had paradoxical PPP induced by biologic therapy, and these patients had significantly increased mean DLQI and prevalence of PsA (r = 0.03, P = 0.001). CONCLUSION Our data suggest that smoking is a risk factor for both PPP development and disease severity. Patients with PPP with PsV present distinct clinical features and patients with biologic therapy-induced paradoxical PPP have reduced quality of life and are more likely to have PsA.

Abstract
RATIONALE Maternal psychosocial stress might be associated with development of allergic diseases in the offspring. OBJECTIVES To evaluate the association of maternal depression and anxiety with ever wheezing and recurrent wheezing among infants and to assess the role of maternal hypothalamo-pituatary-adrenal axis changes and fetal immune response in this association. METHODS This study encompasses two designs; cohort design was developed to evaluate the association of prenatal depression with development of wheezing in infants while nested case-control design was used to assess the role of maternal cortisol and tetranectin and cord blood interleukin 13 and interferon γ. RESULTS We enrolled 697 pregnant women. Elementary school graduate mother (odds ratio [OR] = 1.5, p = .06), maternal smoking during pregnancy (OR = 3.4, p = .001), familial history of asthma (OR = 2.7, p < .001) increased the risk of ever wheezing. Elementary school graduate mother (OR = 2.6, p = .002), maternal smoking during pregnancy (OR = 4.8, p < .001) and familial history of asthma (OR = 1.7, p = .01) increased the risk of recurrent wheezing. Maternal previous psychiatric disease, or Edinburgh Postnatal Depression Scale or Spielberger State-Trait Anxiety Inventory scores were not associated with wheezing. Maternal tetranectin levels were significantly higher among never wheezers compared to the ever wheezers (264.3 ± 274.8 vs. 201.6 ± 299.7, p = .04). CONCLUSIONS In conclusion, the major risk factors for ever wheezing and recurrent wheezing were maternal smoking, level of education and family history of asthma. However, maternal depression and anxiety were not determined as risk factors for wheezing. Maternal tetranectin carries potential as a biomarker for wheezing in the infant.

Abstract
Diagnosing asthma in children represents an important clinical challenge. There is no single gold standard test to confirm the diagnosis. Consequently, both over-, and under-diagnosis of asthma are frequent in children.A Task Force (TF) supported by the European Respiratory Society has developed these evidence-based clinical practice guidelines for the diagnosis of asthma in children aged 5-16 years using nine PICO (Population, Intervention, Comparator and Outcome) questions. The TF conducted systematic literature searches for all PICO questions and screened the outputs from these, including relevant full text articles. All TF members approved the final decision for inclusion of research papers. The TF assessed the quality of the evidence using the GRADE (Grading of Recommendations, Assessment, Development and Evaluation) approach.The TF then developed a diagnostic algorithm based on the critical appraisal of the PICO questions, preferences expressed by lay members and test availability. Proposed cut-offs were determined based on the best available evidence. The TF formulated recommendations using the GRADE Evidence to Decision framework.Based on the critical appraisal of the evidence and the Evidence to Decision Framework the TF recommends spirometry, bronchodilator reversibility testing and FeNO as first line diagnostic tests in children under investigation for asthma. The TF recommends against diagnosing asthma in children based on clinical history alone or following a single abnormal objective test. Finally, this guideline also proposes a set of research priorities to improve asthma diagnosis in children in the future.

Abstract
Abstract
Introduction
Surgical early menopause is early menopause due to medical reasons rather than the natural aging process. Pulse wave velocity (PWV) and augmentation index (AIx) are simple and non-invasive parameters for assessment of arterial stiffness. The aim of this study investigated the arterial stiffness in the surgical early menopause patients.
Method
We included 40 patient early surgical menopause and 40 control group patients with clinically and demographically similar characteristics. Oscillometric measurement method with Mobil-O-Graph 24h-ABPM NG® arteriography was used to measure the arterial stiffness and cardiovascular hemodynamic parameters.
Results
Of the 40 patients who underwent surgical early menopause, 27 (67.5%) had malignancy, 11 (27.5%) with myoma and 2 (5%) with bleeding. There were no differences in baseline demographic, laboratory, echocardiographic parameters and coronary artery disease risk factors.In terms of arterial stiffness parameters, PWV were significantly higher in the early surgical menopause group than in the control group (6.5±0.8; 5.6±1.2 p<0.001), but there was no statistically significant difference in Alx (28.3±10.9; 27.4±9.0 p=0.69).Also, there was no statistically significant difference in terms of cardiac hemodynamic parameters and central aortic pressures.
Conclusion
When arterial stiffness is noninvasively evaluated by oscillometric method, it is significantly increased in surgical early menopause patients independent of other risk factors.

Abstract
BACKGROUND This study was conducted to determine the morphometric features and to make the three-dimensional (3D) reconstruction of the images obtained by computed tomography (CT) of the main long bones (femur, tibia, fibula) in Van cats, and to reveal the biometric differences between these measurement values of both sexual dimorphism and homotypic variations. MATERIALS AND METHODS A total of 16 adult Van cats, 8 male and 8 female, were used in the study. The pelvic limb long bones of the cats, which were anesthetized with the ketamine-xylazine combination, were scanned with a CT device and their images were obtained. These images were converted to a 3D structure by means of MIMICS 20.1 (The Materialise Group, Leuven, Belgium) software programme. Then, morphometric, volumetric, surface arae measurements of these bones were calculated and statistical analyses were performed. RESULTS In the analysis, it was observed that right greatest length (GL), left GL, right greatest length from caput ossis femoris (GLc), left greatest breadth of the distal end (Bd), right volume (V), and left V measurement values of the femur; left GL1, right greatest breadth of the proximal end (Bp), right Bd, left Bd, right smallest breadth of the diaphysis (SD), right V, left V, and right surface area (SA) measurement values of the tibia; right V, left V, right SA, and left SA measurement values of the fibula were statistically significantly higher in male cats than in female cats (p < 0.05). The volume and surface area measurement values of the femur, tibia and fibula of male and female cats were determined as 8.57 ± 1.33 cm3 and 7.00 ± 0.49 cm3, 64.28 ± 6.72 cm2 and 59.42 ± 4.72 cm2; 7.56 ± 1.28 cm3 and 6.15 ± 0.52 cm3, 56.89 ± 6.47 cm2 and 52.72 ± 3.15 cm2; 1.10 ± 0.17 cm3 and 0.83 ± 0.05 cm3, 14.18 ± 1.61 cm2 and 11.95 ± 0.48 cm2, respectively. CONCLUSIONS The statistical differences between the sexes in terms of the measurement parameters of the femur, tibia and fibula in adult Van cats were determined. We believe that these differences can be used in determining morphological variations of Van cats. In addition, it is thought that the data obtained from the present study would be beneficial to veterinary physicians in the clinical application areas in order to evaluate the pathological conditions related to these bones and to the studies in the field of zooarchaeology.

Abstract
It is possible to rehabilitate fully edentulous patients with implantsupported fixed or removable prostheses; however, implantsupported fixed prostheses are the gold standard for patients who not prefer to use removable dentures. This case report, prosthetic rehabilitation of a completely edentulous young patient with an implantsupported fixed hybrid prosthesis using the "Malo Bridge" technique is described. A 18 years old male patient was referred to the clinic with complaints of tooth loss, aesthetics, function, and phonetic. A total of 5 implants were placed in both the jaws. Considering that screw holes may cause aesthetic problems due to the Class III occlusion, these problems have been solved with the implant-supported hybrid prosthesis called Malo bridge. With the Malo Bridge design, the patient's aesthetic, functional and phonetic loss was eliminated, patient comfort and quality of life were improved, and patient expectations were met. It is a viable treatment option to rehabilitate completely edentulous jaws with a cross relationship and increase interarch distance using Malo Bridge to support a fixed prosthesis.

Abstract
INTRODUCTION Cystic fibrosis (CF) is characterized with chronic inflammation with neutrophil and related cytokines in airway secretions. We aimed to measure the levels of neutrophil related inflammatory markers as nitric oxide, IL-8, IL-17, leukotriene B4 and neutrophil elastase as well as e-cadherin in exhaled breath condensate (EBC), and to determine their relation with clinical findings. METHODS We consecutively enrolled cystic fibrosis patients into our clinics between the age of six and eighteen years who could cooperate for exhaled breath condensate to this case-control study (n = 30). The age and sex matched control group (n = 26) was enrolled. Spirometry was performed during the stable period and EBC samples were obtained for measurement of the markers. RESULTS The mean age of the subjects enrolled was 12.1(4.2) years and 40% were positive for P.Aeruginosa in sputum. Subjects who had P.Aeruginosa in sputum cultures had significantly lower FEV1, FVC and FEF 25/75 values compared to the ones without P.Aeruginosa (p = 0.002, p = 0.002 and p = 0.005 respectively). EBC neutrophil elastase levels were significantly higher in the CF patients compared to non-CF controls (3.11 ± 4.71 versus 0.90 ± 2.68, p = 0.04). Nitric oxide, IL-17, IL-8, e-cadherin, neutrophil elastase or leukotriene B4 levels in EBC of CF patients were not related to P.Aeruginosa s infection, FEV1 levels or hospital admission in the last year. CONCLUSION In our study, neutrophil elastase levels in EBC are higher in CF patients compared to non-CF controls. This is independent of acute infection and is evidence to the persistence of neutrophilic lung injury. However, EBC NO, IL-8, IL-17, e-cadherin, neutrophil elastase and leukotriene B4 levels as inflammatory markers, are not correlated with disease progression or clinical findings.

Abstract
The 2019 novel coronavirus (SARS-CoV-2) is endangering human health worldwide; scarcity of published pediatric cases and current literature and the absence of evidence-based guidelines necessitate international sharing of experience and personal communication. On 31 March 2020 the International Committee of the American Thoracic Society Pediatrics Assembly recorded an online podcast, during which pediatric pulmonologists worldwide shared their experience on the novel coronavirus disease (COVID-19) in children. The aim was to share personal experience in organizing pediatric care in different health care settings globally, protecting health care workers, and isolation practices. This manuscript summarizes the common themes of the podcast which centered around three main topics: more benign clinical disease and progression in pediatric cases compared to adults, a strong need for strategies to protect health care workers, and social or economic disparities as a barrier to successful pandemic control.

Abstract
This study was carried out in order to identify the body measurements of two different Dromedary camel breeds raised in Algeria. The animal material of the study consisted of a total of 115 animals belong to Steppe (n = 55) and Sahraoui (n = 60) camel breeds. Eye and coat colors along with body measurements such as head length, neck length, neck girth, tail length, distance between eyes, distance between ears, body length, withers height, chest girth, and live weight were determined. Least squares means for head length, neck length, neck girth, tail length, distance between eyes, distance between ears, body length, withers height, chest girth, and live weight are found 48.2, 116.9, 65.7, 55.6, 24.1, 22.5, 152.2, 184.5, 141.2 cm, and 217.2 kg for Steppe and 48.1, 101.2, 56.2, 51.2, 23.4, 18.3, 135.6, 167.3, 176.8 cm, and 298.9 kg for Sahraoui camel breeds, respectively. The distribution of brown and black eye colors for the Steppe camel breed is as 58.2% and 41.8%, respectively, while all of the Sahraoui camels studied had a brown eye color. The proportional distribution in terms of body color included are coffee, dark coffee, and red colors for 1.8%, 83.6%, and 14.6% in the Steppe camel and 98.3%, 1.7%, and 0.0% for the Sahraoui camel, respectively. As a result, this study concluded that the withers height and chest girth could estimate the body weight in the two breeds of camels with different ages.

Abstract
Cattle plays a very important role in agriculture and food security in Algeria. In the present study, the genetic diversity and structure of Algerian indigenous cattle populations were evaluated by microsatellite markers. A total of 138 individuals belonging to four cattle breed populations were characterized using 22 microsatellite markers. A total of 360 alleles was detected across studied all loci. Results obtained for the mean number of alleles (16.36), expected heterozygosity (0.84) and polymorphic information content (0.82) indicated that the total analyzed populations are characterized by noticeable genetic variability. It can be said that there is a low genetic differentiation in the cattle populations studied considering obtained mean FST value (0.039). It was revealed 97.10% of the total genetic variation can be explained by genetic differences among individuals while 2.90% among populations. The structure, factorial correspondence analysis results and dendrogram showed that cattle populations studied are clustered in three groups. The present study has revealed an important knowledge about the genetic diversity and the relationship between some native cattle breeds raised in Algeria. The results showed that the breeds studied have a high genetic diversity. Moreover, it can be said that microsatellite markers used can be successfully used to determine genetic diversity and population structure in Algerian cattle breeds.

Abstract
INTRODUCTION Laparoscopic pyeloplasty for ureteropelvic junction obstruction in children has gained increasing importance over the last decade. Intracorporeal knot tying still remains a technical challenge for the surgeon. Self-anchoring suture incorporates a new concept for tissue approximation and reduces intracorporeal knot tying problems. There are very few reports on self-anchoring knotless suture and its application for laparoscopic pyeloplasty in children. We present our results of a series of consecutive children undergoing laparoscopic pyeloplasty with knotless barbed sutures. MATERIAL AND METHOD We prospectively evaluate 15 consecutive patients who underwent laparoscopic pyeloplasty with knotless barbed sutures (V-LocTM, Covidien) for ureteropelvic anastomosis. The decision of the operation was given by pediatric nephrology-urology-radiologic imaging diagnostic team, and all patients were operated by a single surgeon. Pyeloplasty was performed without pelvic reduction, and the anastomosis was made by barbed sutures using running fashion. RESULTS The mean age of the patients were 5.39 (3 months-17 years). Two cases had undergone a right-sided pyeloplasty, and thirteen had undergone a left-sided pyeloplasty. The duration of the operative procedure was 60-110 min. Neither intraoperative nor postoperative complication was encountered in any of the cases. Patients were followed by ultrasonographic evaluation. The anteroposterior diameter (AP) diameter of renal pelvis and hydronephrosis grade Society for Fetal Urology (SFU) are significantly different when compared with pre-operative and postoperative period (p = 0.001 and p = 0.001, respectively). Owing to the renal parenchymal thickness change by age pre-operative and postoperative thickness comparison is adjusted by age, because age is considered as a covariate (confounder variable). We observed statistically significant (p = 0.003) difference in parenchymal thickness in all cases. Follow-up periods of the 15 consecutive pediatric pyeloplasty cases were 6-54 months. CONCLUSION In the present study, successful outcome of the laparoscopic pyeloplasty using barbed suture was shown for the first time in children in literature. We believe that successful outcome of laparoscopic pyeloplasty could be achieved by eliminating knots and less manipulation on the wound edge also minimizes tissue injury during the procedure.

Abstract
BACKGROUND This document presents the American Thoracic Society clinical practice guidelines for the diagnosis of primary ciliary dyskinesia (PCD). TARGET AUDIENCE Clinicians investigating adult and pediatric patients for possible PCD. METHODS Systematic reviews and, when appropriate, meta-analyses were conducted to summarize all available evidence pertinent to our clinical questions. Evidence was assessed using the GRADE (Grading of Recommendations, Assessment, Development and Evaluation) approach for diagnosis and discussed by a multidisciplinary panel with expertise in PCD. Predetermined conflict-of-interest management strategies were applied, and recommendations were formulated, written, and graded exclusively by the nonconflicted panelists. Three conflicted individuals were also prohibited from writing, editing, or providing feedback on the relevant sections of the manuscript. RESULTS After considering diagnostic test accuracy, confidence in the estimates for each diagnostic test, relative importance of test results studied, desirable and undesirable direct consequences of each diagnostic test, downstream consequences of each diagnostic test result, patient values and preferences, costs, feasibility, acceptability, and implications for health equity, the panel made recommendations for or against the use of specific diagnostic tests as compared with using the current reference standard (transmission electron microscopy and/or genetic testing) for the diagnosis of PCD. CONCLUSIONS The panel formulated and provided a rationale for the direction as well as for the strength of each recommendation to establish the diagnosis of PCD.

Abstract
The aim is to discuss the contribution of the DR-70 for the patients with high PSA level and which cutofflevel of DR-70 must be consideredthe biopsy decision. 93 patients with high prostate specific antigen level were enrolled into the study. Before the prostate biopsy, total PSA (tPSA), free PSA (fPSA), free/total PSA rate (f/tPSA), PSA density (PSAD) and DR-70 levels were recorded. The patients were divided into two groups according to the pathological outcome of benign (G1) or malignant (G2). G1 and G2 were compared with Mann-Whitney U test, Spearman's rho and ROC curve for analysis. The significance level is taken as .05 for all tests. The median age of patients in G1 and G2 was 62.52 and 68.22 years, respectively. The mean PV in G1 and G2 were 52.16 and 39.6 mL, respectively. The mean tPSA, PSAD and DR-70 levels in G1 and G2 were found as 7.19 and 18.74 ng/mL, 0.14 and 0.48 ng/mL/cc and 0.44 and 0.5 µg/mL, respectively. The mean age of the patients in G2 was statistically significantly higher than G1 (p=.001).The mean PV of the patients in G2 was statistically significantly lower than G1 (p=.001).The mean PSAD of the patients in G2 was statistically significantly higher than G1 (p=.001). There was no statistically significant difference on DR-70 levelsbetween G1 and G2 (p=.38). In Spearman's rhocorrelationanalysis, there was nostatistically significant relationships between DR-70 levels and pathology results in G2 (p=.24). ROC curve of tPSA, fPSA, f/tPSA, PSAD and DR-70 levelswere evaluated. ROC curve of PSAD shows a fair discriminant power with AUC = 0.71 (95% CI: 0.607-0.828) for differentiation between PCa and benign tissue in prostate biopsy with moderate specificity and high sensitivity (62.5% and 75.7%, resp., cut-off level: 0.1377 ng/mL). Contrary to literature and guidelines, cutoff level of PSAD as 0.13ng/mL/cc should be kept in mind and accordingly, a biopsy decision should be made. We think that DR-70 is no needed for additional evaluation before prostate biopsy.

Abstract
Background Identification of the immune response against tuberculosis is vital to develop new diagnostic and therapeutic modalities. The objective of this study was to determine IL (interleukin)-18 and IL-27 responses of peripheral blood mononuclear cells to early secreted antigen (ESAT-6) and culture filtrate protein-10 (CFP-10) stimulation in children with a (+) or (−) tuberculin skin test (TST) with in-house tuberculosis contact.
Methods We enrolled 40 children aged 1 to 5 years who had an in-house contact with a tuberculous adult. Blood samples were obtained from all children for QuantiFERON tuberculosis (TB) gold in tube (QFT-GIT), and peripheral blood mononuclear blood cell culture tests. The subjects were grouped as TST (−) QFT-GIT (−), TST (+) QFT-GIT (−), and TST (+) QFT-GIT (+). Supernatant of peripheral blood mononuclear cell culture was separated with and without stimulation of ESAT-6 and CFP-10, and IL-18 and IL-27 levels were measured with enzyme linked immunoassay (ELISA) test.
Results The study group included 22 boys and 18 girls with mean age 4.25 ± 0.9 years. IL-18 and IL-27 levels were statistically significant in ESAT-6/CFP-10-stimulated supernatants of peripheral blood mononuclear cell (PBMC) samples among the three groups (p = 0.000, p = 0.007, respectively). IL-18 levels between the TST (−) QFT-GIT (−) and TST (+) QFT-GIT (+) groups were significantly different (p = 0.026). Both IL-18 and IL-27 levels were significantly different between ESAT-6/CFP-10 stimulated PBMC supernatants of TST (−) QFT-GIT (−) and TST (+) QFT-GIT (−) groups (p = 0.000, p = 0.003, respectively).
Conclusion Low IL-18 and IL-27 responses of peripheral blood mononuclear cells in children with Bacillus Calmette–Guérin (BCG) vaccine may play a role in Mycobacterium tuberculosis infection after in-house contact.

Abstract
INTRODUCTION This study aimed to investigate the neurotoxic damage of formaldehyde (FA), which is commonly used in medicine and industrial fields, for the hippocampus of rats and the protective role of thymoquinone (TQ) against this neurotoxicity. METHODS There were five groups with eight rats in each. Two control groups were formed, in one of them physiological saline was applied and in the other one corn oil was applied. FA was injected in Group 3. Group 4 was exposed to FA and TQ simultaneously. Group 5 received TQ only. At the end of the experiment animals were sacrificed and brain tissues were removed for biochemical and histopathological investigation. RESULTS catalase (CAT), glutathione peroxidase (GSH-px) and superoxide dismutase (SOD), all known as enzymes with antioxidant activities, were increased in FA and TQ simultaneously administered group. FA caused prominent subarachnoidal hemorrhage and vacuolization. Vacuolization was not observed but occasional subarachnoidal hemorrhage was detected in the FA+TQ group. CONCLUSION Neurotoxic damage in hippocampus induced by FA was reverted by administration of TQ (Tab. 1, Fig. 1, Ref. 26).

Abstract
OBJECTIVES Dysphagia is described as a geriatric syndrome that occurs more frequently with aging. It is associated with the deterioration in functionality however, it is usually ignored. Frailty is a geriatric syndrome that is recognized more with its well-known adverse consequences. Very recently, dysphagia has been suggested to accompany frailty in older adults. We aimed to investigate the association between dysphagia and frailty in the community dwelling older adults. DESIGN Prospective, cross-sectional study. SETTING Geriatric outpatient clinic. PARTICIPANTS Older adults aged ≥60 years. MEASUREMENTS Dysphagia was evaluated by EAT-10 questionnaire and frailty by FRAIL scale. Handgrip strength (HGS) was evaluated by hand-dynamometer. Gait speed was evaluated by 4-meter usual gait speed (UGS). Nutritional status was assessed by mini-nutritional assessment-short form (MNA-SF). RESULTS 1138 patients were enrolled. Mean age was 74.1±7.3 years. EAT-10 questionnaire was answered by all and FRAIL-scale by 851 subjects. EAT-10 score >15 points was regarded as significant dysphagia risk. The participants with EAT-10>15 points were older when compared to the participants with EAT-10<=15 points (p=0.002). Among participants with EAT-10>15 points, women gender and neurodegenerative diseases were more prevalent (p=0.04, p=0.002; respectively); number of chronic diseases, number of drugs and FRAIL score were higher (p=0.001 for each), and HGS, UGS, MNA-SF scores were lower (p=0.002, p=0.01, p<0.001; respectively). In multivariate analyses, the factors independently associated with presence of EAT-10 score>15 were FRAIL score and the number of drugs. CONCLUSION Dysphagia is associated with frailty irrespective to age, presence of neurodegenerative diseases, number of chronic diseases and drugs. To our knowledge, this is the largest serie in the literature providing data on independent association of dysphagia with frailty.

Abstract
OBJECTIVE To compare the diagnostic value of the SARC-F combined with calf circumference (SARC-CalF) with the standard SARC-F to screen sarcopenia in community-dwelling older adults. DESIGN Cross-sectional, diagnostic accuracy study. SETTING Geriatric outpatient clinic of a university hospital. PARTICIPANTS Older adults >= 65 years. MEASUREMENTS Muscle mass (bioimpedance analysis device), muscle strength (hand grip strength-Jamar hydraulic hand dynamometer), and physical performance (usual gait speed). Four currently used diagnostic criteria [European Working Group on Sarcopenia in Older People (EWGSOP), Foundation for the National Institutes of Health (FNIH), International Working Group on Sarcopenia (IWGS), and Society on Sarcopenia Cachexia and Wasting Disorders (SCWD) criteria] were applied. SARC-CalF was performed by using two different calf circumference threshold: standard cut-off 31 cm (SARC-CalF-31) and national cut-off 33 cm (SARC-CalF-33). The sensitivity/specificity analyses of the SARC-CalF and SARC-F tools were run. We used the receiver operating characteristics curves and the area under the receiver operating characteristics curves (AUC) to compare the diagnostic accuracy to identify sarcopenia. RESULTS We included 207 subjects; 67 male and 140 female with a mean age of 74.6±6.7 years. The prevalence of sarcopenia ranged from 1.9% to 9.2%. The sensitivity of SARC-F was between 25% (EWGSOP) and 50% (IWGS); specificity was about 82%. For SARC-CalF-31 and SARC-CalF-33 sensitivity was in general similar -between 25-50%- which pointed out that SARC-CalF was not superior to SARC-F for sensitivity in this sample. Corresponding specificities for SARC-CalF-31 and SARC-CalF-33 were higher than SARC-F and were between 90-98%. Additionally, the AUC values, which indicates the diagnostic accuracy of a screening test, were in general higher for SARC-CalF-33 than the SARC-F and SARC-CalF-31. CONCLUSIONS We reported that addition of calf circumference item to SARC-F tool improved the specificity and diagnostic accuracy of SARC-F but it did not improve the sensitivity in a community-dwelling Turkish older adult population sample that had low prevalence of sarcopenia. The performance of SARC-CalF tool to screen sarcopenia is to be studied in different populations and living settings.

Abstract
CONTEXT DEXA is recommended for osteoporosis screening. However, the rate of screening with DEXA is very low. Therefore, methods that can be used more easily and cost effectively are needed. OBJECTIVE The objective of this study is to develop a clinical risk assessment tool of osteoporosis (OSTEORISKAPP) by using syndromic approach. DESIGN A methodological study was performed. SUBJECTS AND METHODS Three hundred and fifty-six participants who are above 50 years old are participants of study and take history and physical examination. Positive likelihood ratio (LR), pre and post test probability, is calculated. A logistic regression analysis and a ROC analysis are made with the model constructed by those criteria. RESULTS Eighteen different clinical risk indices are diagnosed. According to LR, 4 of these criteria are minimally effective, 11 of them are weakly effective and 3 of them are medium effective criteria According to results of logistic regression analysis, back pain, waist pain, and usage of cortisone for more than 3 months, vertebra tenderness in physical examination, having dorsal kyphosis and being obese are turned out to be statistically significant in 89.9% confidence interval. AUC is found to be 0.948 and diagnostic test is found to have perfect distinction ability. CONCLUSION Syndromic diagnostic criteria that will be used for osteoporosis screening of population and that is cost effective, no need to refer, practical, reliable and has tried to be developed.

Abstract
OBJECTIVE To assess the reliability and validity of Turkish version of SARC-F in regard to screening with current definitions of sarcopenia, muscle mass and functional measures. DESIGN Cross-sectional study. PARTICIPANTS Community-dwelling older adults aged >=65 years admitting to a geriatric outpatient clinic. MEASUREMENTS Muscle mass (bioimpedance analysis), handgrip strength, usual gait speed, chair sit-to-stand test, functional reach test, short physical performance battery, SARC-F questionnaire, FRAIL questionnaire Sarcopenia was evaluated with 4 current different definitions: European Working Group on Sarcopenia in Older People's (EWGSOP); Foundation for the National Institutes of Health (FNIH), International Working Group on Sarcopenia (IWGS) and Society on Sarcopenia, Cachexia and Wasting Disorders (SCWD). RESULTS After cross-cultural adaptation, 207 subjects were analysed in the clinical validation study. Mean age was 74.6±6.7 years, 67.6% were women. Against EWGSOP, FNIH, IWGS and SCWD definitions of sarcopenia, sensitivity of SARC-F were %25, 31.6%, 50% and 40%; specificity were 81.4%, 82.4%, 81.8% and 81.7%, respectively. Positive predictive values were between 5.1-15.4% and negative predictive values were 92.3-98.2%. Against parameters of low muscle mass, sensitivity were about 20% and specificity were about 81%. Against parameters of function; for low hand grip strength, sensitivity of SARC-F were 33.7% (for Turkish cut-off); 50% (for FNIH cut-off); specificity were 93.7% (for Turkish cut-off) and 85.8% (for FNIH cut-off). Against low UGS, poor performance in chair sit to stand test, functional reach test, SPPB and presence of positive frailty screening sensitivity were 58.3%, 39.2%, 59.1%, 55.2% and 52.1% while specificity were 97.3%, 97.8%, 88.1%, 99.3% and 91.2%, respectively. CONCLUSION The psychometric performance of Turkish SARC-F was similar to the original SARC-F. It revealed low sensitivity but high specificity with all sarcopenia definitions. Sensitivity and specificity were higher for muscle function tests reflecting its inquiry and input on functional measures. Our findings suggest that SARC-F is an excellent test to exclude muscle function impairment and sarcopenia. SARC-F is relatively a good screening test for functional measures.

Abstract
The aim of this study is to assess the influence of darbepoetin on the development of peritoneal fibrosis in rats induced by Chlorhexidine gluconate (0.1%) and ethanol (15%) and to determine the effect on peritoneal tissue levels of MMP–2 and TIMP–2, possible important factors in progression of peritoneal fibrosis. Twenty-four female Wistar albino rats were divided into three groups. The first group (CH group) received 3 ml/200g daily intraperitoneal injections of Chlorhexidine gluconate (0.1%) and ethanol (15%) dissolved in saline to induce chemical peritonitis; group 2 (ESA group) received 3 ml/200g daily injections of Chlorhexidine gluconate (0.1%) and ethanol (15%) dissolved in saline and also darbepoetin 12.5 microgr/ per kilogram/ day subcutaneously on the first and seventh days; group 3 (Control group) received intraperitoneal 0.9% saline (3 ml/200g/d) through the right lower quadrant by 21 gauge needle. The study duration was fourteen days. On the fifteenth day rats were sacrificed, parietal peritoneum samples were obtained from the left anterior abdominal wall. Pathological samples were examined using Hematoxyline & Eosin (HE) stains. The thickness, vasculpathy, and inflammation were determined by light microscopy. MMP-2 and TIMP-2 were studied immunohistochemically by monoclonal antibody staining. The activity of MMP-2 on peritoneal tissue was studied by gelatin zymography and TIMP–2 protein level was analysed by ELISA, biochemically. The decrease in thickness of parietal peritoneum in group ESA was statistically significant when compared to CH group (p<0.05). Inflammation scores, and vascularization score surfaces were not statistically different between these groups (p>0.05). Immunohistochemically, darbepoetin was shown to decrease MMP-2 expression on parietal peritoneum in CH group (p<0.05), but had no effect on TIMP-2 (p>0.05). Biochemically the ratio of active MMP–2 to proMMP–2 was more significantly increased in the ESA group than in the CH group (p<0.001), however, TIMP- 2 levels in both groups were decreased compared to the control group (p<0.05). Darbepoetin histopathologically reduced peritoneal fibrosis induced by Chlorhexidine gluconate. We can suggest that Darbepoetin does not cause peritoneal fibrosis and may prevent peritoneal fibrosis in rats possibly related to an effect on MMP-2 expression. Further research regarding the utility and dosage should be considered.

Abstract
This paper presents a multi objective mixed integer location/routing model that aims to minimize transportation cost and risks for large-scale hazardous waste management systems (HWMSs). Risks induced by hazardous wastes (HWs) on both public and the environment are addressed. For this purpose, a new environmental impact definition is proposed that considers the environmentally vulnerable elements including water bodies, agricultural areas, coastal regions and forestlands located within a certain bandwidth around transportation routes. The solution procedure yields to Pareto optimal curve for two conflicting objectives. The conceptual model developed prior to mathematical formulation addresses waste-to-technology compatibility and HW processing residues to assure applicability of the model to real-life HWMSs. The suggested model was used in a case study targeting HWMS in Turkey. Based on the proposed solution, it was possible to identify not only the transportation routes but also a set of information on HW handling facilities including the types, locations, capacities, and investment/operational cost. The HWMS of this study can be utilized both by public authorities and private sector investors for planning purposes.

Abstract
OBJECTIVES Prenatal and postnatal smoke exposures are associated with many lung diseases in children due to impaired lung function, increased inflammation, and oxidative stress. We aimed to determine the influence of secondhand tobacco smoke exposure on the levels of nasal glutathione, IL-8, IL-17, MMP-9, and TIMP-1, as well as serum surfactant protein-D (SP-D) in wheezy children. METHODS We enrolled 150 children with recurrent wheezing and recorded wheezing characteristics at enrollment. We measured the levels of serum cotinine, SP-D, nasal glutathione, IL-8, IL-17, MMP-9, and TIMP-1. Serum cotinine levels between 3 and 12 ng/mL, and above 12 ng/mL were defined as lower and higher level secondhand tobacco smoke exposure, respectively. The ANOVA test, Pearson's correlation analysis and multivariate analysis with a linear regression test were used for the statistical analysis. RESULTS Ninety-one children had been exposed to lower level secondhand tobacco smoke, while 24 children were exposed to higher level secondhand tobacco smoke. Thirty-five children were not exposed to cigarette smoke. Wheezing symptom scores were higher in exposed children (p = 0.03). Levels of other biomarkers showed no significant difference. CONCLUSIONS Secondhand tobacco smoke exposure is associated with more severe respiratory symptoms in wheezing children. However, levels of nasal or serum inflammatory markers fail to explain this association, either because of different mechanical factors in the process or due to low levels of the biomarkers especially in nasal secretions.

Abstract
BACKGROUND Infantile wheezing is a common problem, but there are no guidelines for the evaluation of infants with recurrent or persistent wheezing that is not relieved or prevented by standard therapies. METHODS An American Thoracic Society-sanctioned guideline development committee selected clinical questions related to uncertainties or controversies in the diagnostic evaluation of wheezing infants. Members of the committee conducted pragmatic evidence syntheses, which followed the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) approach. The evidence syntheses were used to inform the formulation and grading of recommendations. RESULTS The pragmatic evidence syntheses identified few studies that addressed the clinical questions. The studies that were identified constituted very low-quality evidence, consisting almost exclusively of case series with risk of selection bias, indirect patient populations, and imprecise estimates. The committee made conditional recommendations to perform bronchoscopic airway survey, bronchoalveolar lavage, esophageal pH monitoring, and a swallowing study. It also made conditional recommendations against empiric food avoidance, upper gastrointestinal radiography, and gastrointestinal scintigraphy. Finally, the committee recommended additional research about the roles of infant pulmonary function testing and food avoidance or dietary changes, based on allergy testing. CONCLUSIONS Although infantile wheezing is common, there is a paucity of evidence to guide clinicians in selecting diagnostic tests for recurrent or persistent wheezing. Our committee made several conditional recommendations to guide clinicians; however, additional research that measures clinical outcomes is needed to improve our confidence in the effects of various diagnostic interventions and to allow advice to be provided with greater confidence.

Abstract
BACKGROUND Parthenolide is the active constituent of the plant 'Tanacetum parthenium' (Feverfew) which has been used for centuries as a folk remedy for inflammatory conditions. AIM OF THE STUDY In this study we aimed to investigate the effects of parthenolide in a murine model of chronic asthma. MATERIALS AND METHODS Thirty-five BALB/c mice were divided into five groups; I (control), II (placebo), III (dexamethasone), IV (parthenolide) and V (dexamethasone and parthenolide combination). Lung histology was evaluated after treatment with the study drugs. Levels of interleukin (IL)-4 and IL-5 were determined by ELISA. RESULTS Histologic parameters except the number of mast and goblet cells improved in the parthenolide group when compared with placebo. All parameters except basal membrane thickness and number of mast cells were improved significantly better in the group receiving dexamethasone when compared with the parthenolide group. Improvement of most of the histologic parameters was similar in Groups III and V. Interleukin-4 levels were significantly reduced in the parthenolide group when compared to the placebo group. CONCLUSION We demonstrated that parthenolide administration alleviated some of the pathological changes in asthma. But parthenolide alone is not efficient as dexamethasone therapy and the parthenolide and dexamethasone combination also did not add any beneficial effect to the dexamethasone treatment.

Abstract
Airway remodeling is the chronic outcome of inflammation in asthma and a point of intervention between pediatric and adult ages. Pediatric asthma has been of great interest in the efforts to find a valuable time to interrupt remodeling. Various experimental and clinical research have assessed the effect of current therapeutic modalities on airway remodeling in asthma and many new agents are being developed with promising results. The heterogeneity in the results of these studies may lie in the heterogeneity of pathogenesis leading to asthma and remodeling; underlying the need for individualized treatment of the unique pathogenetic characteristics of each child's asthma. The aim of this review is to summarize the evidence about the influence of current and future therapeutic modalities in the concept of inflammation and remodeling in pediatric asthma.

Abstract
CONTEXT Adropin is a peptide hormone implicated in the regulation of insulin sensitivity and energy homeostasis. Polycystic ovary syndrome (PCOS) is a metabolic and reproductive disease associated with insulin resistance. It has been demonstrated that various inflammatory markers increased in PCOS including TNF-α. TNF-α regulates the secretion of certain peptides which play a crucial role in glucose and lipid homeostasis. There is also some evidence of a link between TNF-α and adropin. OBJECTIVE To ascertain whether there is an association between circulating adropin levels and TNF-α in PCOS. PATIENTS AND DESIGN 152 women with PCOS and 152 age- and body mass index-matched controls without PCOS were recruited for this cross-sectional study. MAIN OUTCOME MEASURES Adropin and TNF-α levels were measured using ELISA. RESULTS Adropin levels were lower in the PCOS group compared with the control group (7.43 ± 0.79 vs. 9.42 ± 0.76 ng/ml, P < 0.001), whereas TNF-α levels were higher (49.93 ± 3.39 vs. 35.83 ± 2.47 pg/ml, P < 0.001). A strongly negative correlation was found between circulating adropin levels and TNF-α levels in women with PCOS (r = -0.407, P < 0.001). Binary logistic regression analysis revealed that decreased adropin levels were significantly associated with high odds of having PCOS, although, after adjustment for TNF-α, this link vanished. Additionally, multiple linear regression analysis showed that HOMA-IR and TFN-α independently predicted adropin levels. CONCLUSIONS Serum adropin levels are significantly decreased in PCOS and are inversely associated with TNF-α. Further dissection of the nature of this association can open new therapeutic options for metabolic diseases.
