Abstract
Managing acute abdomen in very low birth weight (VLBW) and premature infants presents a diagnostic challenge, often necessitating a thorough assessment to discern underlying causes. Umbilical venous catheters (UVCs), commonly used in neonatal intensive care, are essential but not without risks. A 29-week premature male infant, born to a 23-year-old mother, was referred to our clinic on the 16th day of life with a suspected diagnosis of necrotizing enterocolitis (NEC). The infant had spent the first day intubated and received non-invasive respiratory support for 15 days. A 5 French UVC was inserted at the 2nd hour of life, and by the 3rd day of life, the infant transitioned to minimal enteral feeding. Between the 12th and 16th days of life, the infant initially diagnosed with NEC due to symptoms such as decreased stool passage and abdominal distension. The patient had been on a continuous course of antibiotic treatment throughout the entirety of his life, commencing on the very first day due to suspected early neonatal sepsis, followed by nosocomial sepsis during the hospitalization, and persisting with antibiotic therapy for suspected NEC. The case took a unique turn upon further evaluation after being referred to our unit. Despite a preliminary NEC diagnosis, further evaluation revealed umbilical catheter complications, leading to total parenteral nutrition extravasation. Removal of the catheter, drainage, and antibiotic adjustment resulted in improved clinical outcomes. In neonatal care, cautious management is vital when dealing with infants exhibiting abdominal symptoms. A nuanced approach, including differential diagnosis and careful antibiotic use, is essential.

Abstract
BACKGROUND The aims of this study were to investigate biliary complications in liver transplant recipients with choledochocholedocho stomy anastomosis, to identify the risk factors for the development of such complications, and to evaluate the success of endoscopic approaches in liver transplant recipients. METHODS Between January 2013 and May 2021, a total of 238 patients with liver diseases underwent liver transplantation: 174 recipients undergoing choledochocholedochostomy anastomosis were included in the analysis. RESULTS Their median age was 54.0 years. The median posttransplant follow-up period was 29 months. Hepatitis B virus infection (33%) was the most common indication for liver transplantation. Most patients (87%) received living donor liver transplantation. The overall prevalence of posttransplant biliary complications was 31%. Anastomotic biliary strictures were the most common biliary complications (72%), followed by biliary leakage (13%). The median time between endoscopic retrograde cholangiography and liver transplantation was 4 months, with a mean of 3 ± 1.6 sessions. Endoscopic retrograde cholangiography-guided drainage and balloon dilation with or without stent placement was the most common treatment modalities for recipients with biliary strictures. The overall success rate of endoscopic treatment modalities was 83.3%, with 65% of the recipients exhibiting complete biochemical and endoscopic responses. The response did not differ significantly between living donor liver transplantation and cadaveric donor liver transplant recipients (P > .05). Three recipients required revision surgery for biliary complication repair. Six patients died due to biliary sepsis. CONCLUSION Biliary stricture and leakages were the most common biliary complications after liver transplantation. Endoscopic treatment was successful in most recipients.

Abstract
Weaning stress is crucial threatening factor in animal breeding. The aim of this study was to investigate the effects of weaning to oxidative stress and stress status of goat kids at the molecular levels. In the study, blood samples were collected at the weaning process (7 days before weaning- Pre-W, Day of weaning- Day-W and 7 days after weaning- Post-W) from 24 healthy Damascus goats. Cortisol, MDA (Malondialdehyde), COX-2 (Cyclooxygenase-2), and NRF2 (Nuclear factor erythroid 2-related factor 2) proteins levels were investigated in plasma, while COX-2 and NRF2 genes expression levels were determined from leukocytes. Compared to Pre-W, COX-2 gene was upregulated almost 2-fold in Day-W. On the other hand, NRF2 gene expression levels were tended to upregulation in Day-W, and it was upregulated approximately 2-fold in Post-W. While MDA levels were gradually increased in the weaning process, the levels of COX-2 and NRF2 proteins showed similar changes with gene expression trends. Positive correlations were also found between cortisol and COX-2 and NRF-2 protein levels in plasma. It was thought that significant outputs gained in terms of MDA levels in plasma of kids at the weaning process. For the first time, determination of COX-2 and NRF2 levels both mRNA and protein levels in the weaning process of goat kids were satisfactorily evaluated in this study. Particularly, NRF2 was found to have the potential to be a fundamental biomarker to assess the oxidative status of weaning kids.

Abstract
BACKGROUND The placenta is the major regulatory element of the in-utero environment, and alterations in placental cellular functions in infection, inflammation, and hypoxemia lead to adverse preterm birth outcomes. The importance of regulation of autophagy and inflammasome activities has been shown in the pathogenesis of morbidities in immature animal models. This study aimed to determine the relationship between placental autophagy and inflammasome activities with morbidity in extremely preterm infants. METHODS Premature infants born between 24th to 29th gestational weeks were evaluated prospectively. Placental LC3B and NLRP3 immunostainings were performed to assess autophagy and inflammasome activities. Preterm morbidities including respiratory distress syndrome (RDS), patent ductus ateriosus: (PDA), intraventricular hemorrhage (IVH), necrotizing enterocolitis (NEC), periventricular leukomalacia (PVL), sepsis, bronchopulmonary dysplasia (BPD), retinopathy of prematurity (ROP) and mortality were evaluated. RESULTS Fifty-nine infants with a mean gestational age of 26.9 ± 1.5 weeks were included. Anti-LC3B staining scores were moderate or intense positive in 75% of the placentas. Anti-LC3B activity was not associated with the existance of evaluated neonatal morbidities or mortality. Autophagy and inflammasome coexistence were demonstrated in 35 placentas (59.3%). Anti-NLRP3 staining score was moderate or intensely positive in 75% of the placentas. Infants with BPD had a lower rate of positive anti -NLRP3 staining than infants without BPD (42.9 vs 57.1%, p=0.048). Infants who had hemodynamic significant patent ductus arteriosus (hsPDA) and surgical- NEC showed significantly intense anti-NLRP3 staining compared to infants who did not (18.8% vs 0%, p= 0.027 and 33% vs 7.5%, p=0.048 respectively). CONCLUSIONS The results showed that autophagy and inflammatory activities were present in varying amounts in the placenta of preterm infants. Association of decreased or increased rates of inflammasome activities with certain diseases such as BPD, hsPDA and surgical-NEC indicates the role of the intrauterin inflammatory process and the importance of critical balance in inflammation. Because of the complex pathophysiology of preterm morbidities, placental autophagy and inflammasome activities seem worthy of further investigation.

Abstract
BACKGROUND Hereditary bone marrow failure syndromes are a category of biologically different syndromes that can cause cytopenia in at least one hematopoietic cell lineage. CASE We present a 29-week-old male infant who had a low Apgar Score, advanced delivery room resuscitation, widespread petechial rash, and ecchymoses at birth, without any dysmorphic features. Initial laboratory tests revealed bicytopenia (platelet count 7x10 3 /uL, hemoglobin of 3.9 g/dL, neutrophil 2.0x103 /uL) with findings of disseminated intravasculer coagulation (DIC). Imaging studies demonstrated accompanying left-sided congenital pulmonary airway malformation. On the second postnatal week pancytopenia occurred and the bone marrow findings were consistent with congenital amegakaryocytic thrombocytopenia. Further evaluations for differential diagnosis of pancitopenia were performed and the results of congenital viral infections, metabolic and immunologic tests were negative. While supportive treatments were in progress, haploidentical bone marrow transplantation (BMT) was performed from the father at 84th day due to unavailability of HLA-matched relative or nonrelative donor. Whole exome sequencing revealed a novel heterozygous frameshift variation (c.1242dupT [p. Thr538fs]) in exon 8 of the MECOM gene and validated by Sanger sequencing. No variation was detected in the parents genetic analysis. CONCLUSIONS In this report, we present a patient with congenital bone marrow failure successfully treated with haploidentic BMT and describe a novel, de novo pathogenic variant in MECOM gene.

Abstract
Background and Objective: Due to limited knowledge on the etiopathogenesis of infantile colic (IC) and the insufficiency of data regarding current treatments, different approaches emerge in terms of diagnosis, and treatment modalities globally and also in Turkey. The objective of this study was to observe how infantile colic is diagnosed and treated by paediatricians in Turkey. Methods: An anonymous electronic questionnaire was used to collect the respondents' opinions. The study questionnaire was comprised of 4 different sections with 56 multiple-choice questions covering demographic features, diagnostic approach, treatment preferences and response to treatment. Results: A total of 375 paediatricians responded to the survey. Fifty three percent of the participants stated that they established the IC diagnosis based only on their clinical experience. Factors that most affected the decision to start treatment were identified as parent discomfort, decreased family quality of life, and crying duration (68, 66, and 54%, respectively). Application of soothing methods, probiotics, and simethicone were identified as the most frequently used treatment modalities (frequency ranking; 81, 76, and 50%, respectively). Of the participants, 98% stated that they used probiotic as supplements, on the other hand, 72% of the participants indicated that they used simethicone as the only medical treatment to treat IC. The question about the participants' observations regarding the response to probiotic treatment was answered by 71% of the participants with decreased crying duration, while easier stool/gas passage and resolved digestion problems were the other frequent observations (54 and 49%, respectively). The observations related to the response to simethicone treatment also included decreased crying duration in addition to decreased crying periods after feeding and easier gas/stool passage (67, 47, and 44%, respectively). Conclusions: Survey results revealed that the majority of the paediatricians used their clinical experience alone to establish the diagnosis of IC and preferred probiotic supplements and simethicone as the only medical treatment to treat IC and they observed clinical benefits from them. Insights generated by this study will be helpful to guide future efforts to improve the management of infantile colic by paediatricians.

Abstract
Introduction Globally, the incidence, as well as mortality, related to hepatocellular carcinoma (HCC) is on the rise, owing to relatively few curative options. Underlying cirrhosis is the most common etiology leading to HCC, but risk factors of cirrhosis show great regional variability. Over the years, there has been a steady development in the diagnostic and therapeutic modalities of HCC, including the availability of a wide range of systemic chemotherapeutic agents. We aim to review the recent advancements in the diagnostic and therapeutic strategies for HCC. Methodology The literature search was done using databases PubMed, Cochrane, and Science Direct, and the latest relevant articles were reviewed. Findings Screening of HCC is a pivotal step in the early diagnosis of the disease. Current guidelines recommend using ultrasound and alfa fetoprotein but various new biomarkers are under active research that might aid in diagnosing very small tumors, not picked up by the current screening methods. Treatment options are decided based upon the overall performance of the patient and the extent of the disease, as per the Barcelona classification. There are very few options that offer a cure for the disease, ranging from liver resection and transplantation to tumor ablation. Downstaging has proven to have a significant role in the course of the disease. An attempt to control the disease can be made via radiological interventions, such as transarterial chemoembolization, transarterial radioembolization, or radiation therapy. For advanced disease, sorafenib used to be the only option until a couple of years ago. Recently, many other systemic agents have received approval as first-line and second-line therapies for HCC. Genomics is an area of active clinical research as understanding the mutations and genomics involved in the evolution of HCC might lead to a breakthrough therapy.

Abstract
Objectives Cholestasis is a common disease of the liver in premature infants and no specific preventive treatment is currently available. Fucose, one of the monosaccharide building blocks of human milk oligosaccharides, may prevent cholestatic hepatic injury by various mechanisms. The aim of this study was to investigate the protective effect of fucose treatment after endotoxin-induced cholestasis in a rat model.
Methods Wistar rat pups were divided into four groups as: group I, control group; group II, fucose-supplemented group; group III, lipopolysaccharide (LPS)-administered group, and group IV, LPS-exposed and fucose-supplemented group. Fucose was given 100 mg/kg i.p. every other day between PN5–17. LPS was administered on PN19 to establish endotoxin-induced cholestasis model. On PN21, animals were sacrificed to evaluate liver cell damage and apoptosis.
Results Fucose supplementation significantly improved the biochemical parameters that deteriorated in LPS-administered group, significantly increased the expression of bile salt export pump, reduced the number of apoptotic cell death, and greatly prevented LPS-induced cholestatic hepatic injury.
Conclusion Given our results, fucose may be useful in reducing hepatic injury and might possess clinical relevance for the preventive treatment of inflammation-induced cholestatic injury in newborns.

Abstract
Respiratory distress syndrome is the leading cause of respiratory failure in preterm infants. The incidence and severity of respiratory distress syndrome are inversely related to the gestational age of the newborn. The major underlying pathophysiologic mechanisms are surfactant deficiency and anatomic, structural immaturity of the lung. Recent improvements such as antenatal steroid treatment to enhance pulmonary maturity, appropriate resuscitation facilitated by placental transfusion and immediate use of continuous positive airway pressure for alveolar recruitment, early rescue administration of surfactant, ventilation with gentler modes to minimize damage to the immature lungs, and the other supportive therapies have significantly decreased respiratory distress syndrome-related morbidity and mortality. This guideline was addressed to overview the mentioned improvements in order to standardize respiratory distress syndrome management in neonatal intensive care units in Turkey.

Abstract
Aim Alpha-fetoprotein (AFP) is still the most commonly used and the single most recommended marker in the diagnosis of hepatocellular carcinoma (HCC). Interleukin (IL)-6 is a circular cytokine and its role on carcinogenesis in various hematological and solid tumors is clearly documented. A combination of serum IL-6 and AFP may provide beneficial information regarding early diagnosis of HCC. In this study, the effect of plasma IL-6 level in the diagnosis of HCC was investigated. Materials and methods A total of 130 patients with liver cirrhosis, together with 30 control cases were enrolled in the trial. A diagnosis of HCC was present in 75 patients (57.6%) in the liver cirrhosis group. Blood samples were obtained from the enrolled study and control cases. Alpha-fetoprotein was quantified by chemiluminescent method. Plasma IL-6 levels of samples obtained at -80°C were quantified by human IL-6 BMS213/2 BMS213/2TEN kit. Results The HCC patients were older than the patients in the cirrhosis group (p = 0.016). On comparison of the HCC patients with the control group, AFP (p < 0.001) and IL-6 (p < 0.001) were significantly higher among the HCC patients. Comparison of HCC patients with liver cirrhosis cases with no diagnosis of HCC revealed significantly high AFP (p < 0.001) and IL-6 levels (p < 0.001) in HCC group. Cutoff value for IL-6 was calculated as 5.73 (pg/mL). No difference was detected in AFP (p = 0.600) and IL-6 (0.344) in all three subgroups. A total of 17 patients died during a mean follow-up period of 32.9 months. No correlation was found between mean AFP values and IL-6 values and survival rates. Conclusion Plasma IL-6 level was found to be significant in the diagnosis of HCC. Alpha-fetoprotein and IL-6 provided no advantage in terms of early diagnosis of HCC and no correlation was observed between these markers and survival.

Abstract
Introduction: CA 19-9 is used as a tumor marker in colon, pancreas, biliary, and gastric cancers. Laryngeal cancer is the most common malignant epithelial tumor among head and neck cancers and has no specific tumor marker. Case report: A 66-year-old male patient had severe reflux symptoms during 5 years and had an isolated CA 19-9 elevation. Follow-up analysis revealed that he had larynx cancer and after laryngectomy, CA 19-9 levels decreased to normal range. Discussion: Currently, CA 19-9 is not a marker for malignancy. Laryngeal carcinoma has no specific tumor marker, but laryngeal squamous cell carcinoma may be manifested by elevated CA 19-9 levels.

Abstract
Introduction Periampullary diverticula (PD) is caused by extraluminal pouching of duodenal mucosa. Using a very common endoscopic procedure to diagnose or treat gastrointestinal disorders, we encountered duodenal diverticulum. Materials and methods This is a retrospective, single-center study. Three thousand and sixteen patients on whom endoscopic retrograde cholangiopancreatography (ERCP) was performed at Ankara University Medical School, Department of Gastroenterology, from June 2009 to June 2014 were included to the study. Results Hundred and thirty patients (males 65, females 65) among the 3,016 had PD. Two hundred and sixty patients without diverticulum were randomly chosen from the 3,016 patients, as a control group [121 (47%) females, 139 (53%) males]. There was no statistical difference between the two groups. The mean age of the patients with PD was 69.9 years, while the mean age was 62.3 years for patients without PD (p < 0.001). Incidence for PD was 4.6%. The papilla of Vater was located in the inter-diverticular area (Type 1) in 9 patients (8.3%), at the edge of the diverticulum (Type 2) in 31 patients (28.4%), and at a distance of 2 to 3 cm from the papilla (Type 3) in 69 patients (63.3%). Discussion Although numerically more common bile duct stones occurred in patients with PD compared to those without PD, there was no statistical difference between the two groups. The rate of pancreato-biliary carcinomas was higher in patients without diverticulum. Cannulation was successful in both groups at the rate of 97.6 and 92% respectively, but cannulation failed more often in patients without PD. Duodenal perforation occurred in one patient with PD. Bleeding after sphincterotomy occurred in two patients without PD. How to cite this article Örmeci N, Deda X, Kalkan Ç, Tüzün AE, Karakaya F, Dökmeci A, Bahar DK, Özkan H, İdilman R, Çınar K.

Abstract
Myxosporeans of the genus Henneguya have a global distribution and infect organs and tissues of both marine and freshwater fishes. Here we describe the morphological, histological and molecular characteristics of Henneguya sinova sp. nov. parasitizing the gill arches of tentacled blenny Parablennius tentacularis (Perciformes: Blenniidae) collected from the coast of Sinop on the Black Sea in Turkey. Several oval whitish plasmodia of different sizes in the gill arches of fish were found. The mature spores were rounded oval in frontal view, with a mean (range) total length 57.5 (51.5-68.0) µm; the spore body was 11.7 (11.3-12.0) µm in length by 7.6 (7.3-8.3) µm in width and 6.7 (6.6-6.8) µm in thickness. The caudal appendages, measuring 46.0 (40.0-55.0) µm in length, were very thin at the tapered end. The prevalence of infection by H. sinova sp. nov. was 35.5%. Phylogenetic analysis of nuclear small subunit ribosomal DNA (SSU rDNA) clearly suggested H. sinova as a new species which is clustered within the marine Henneguya lineage. Pairwise nucleotide similarities and DNA distance values of SSU rDNA between H. sinova sp. nov. and other related Henneguya species also supported this suggestion.

Abstract
Effective breeding programs based on genetic diversity are needed to broaden the genetic basis of rice (Oryza sativa L.) in Turkey. In this study, 81 commercial varieties from seven countries were studied in order to estimate the genomic relationships among them using nine inter-primer binding site (iPBS)-retrotransposon and 17 simple-sequence repeat (SSR) markers. A total of 59 alleles for the SSR markers and 96 bands for the iPBS-retrotransposon markers were detected, with an average of 3.47 and 10.6 per locus, respectively. Each of the varieties could be unequivocally identified by the SSR and iPBS-retrotransposon profiles. The iPBS-retrotransposon- and SSR-based clustering were identical and closely mirrored each other, with a significantly high correlation (r = 0.73). A neighbor-joining cluster based on the combined SSR and iPBS-retrotransposon data divided the rice varieties into three clusters. The population structure was determined using the STRUCTURE software, and three populations (K = 3) were identified among the varieties studied, showing that the diversity harbored by Turkish rice varieties is low. The results indicate that iPBS-retrotransposon markers are a very powerful technique to determine the genetic diversity of rice varieties.

Abstract
BACKGROUND/AIMS To evaluate the effectiveness of tenofovir in patients with chronic hepatitis B infection in a real life setting. MATERIALS AND METHODS We performed a retrospective analysis of data from 164 patients with chronic hepatitis B who were treated with Tenofovir. Eighty-six patients (52.4%) were naïve. Seventy-seven (46.9%) patients were previously treated with anti-viral drugs, including standard interferon (n=4), pegylated (PEG) interferon (n=14), standard interferon together with lamivudine (n=13), lamivudine alone (n=41), adefovir (n=2), lamivudine together with adefovir (n=1), and entecavir (n=2). Six patients (3.7%) had liver cirrhosis before treatment of tenofovir. RESULTS The patients who have hepatitis B viral DNA>104 copy/mL with chronic hepatitis B infection were included in the treatment of Tenofovir. Average follow up time was 30.31±14.33 months. HBV DNA negativity and alanine aminotransferase (ALT) normalization were 86.5% and 71.3%, respectively, at the last visit. Hepatitis B e-Antigen (HBeAg) seroconversion occurred in 11 (19.6%) out of 164 patients. During the follow-up period, 4 (2.4%) patients developed liver cirrhosis and in 5 (3%) patients hepatocellular carcinoma (HCC) occurred out of 164 patients. HBsAg seroconversion occurred in one patient (0.6%). CONCLUSION Tenofovir can be used safely and successfully in those patients that were naive, experienced with immune modulators and/or antivirals, HBeAg-positive, and HBeAg-negative patients.

Abstract
OBJECTIVE The aim of this study was to determine the serum mannose-binding lectin (MBL) levels and the frequency of MBL gene polymorphisms in infants with neonatal sepsis. STUDY DESIGN Between January 2008 and January 2010, a total of 93 infants were included in this study and 53 of them had neonatal sepsis diagnosis as study group and 40 infants who had no sepsis according to clinical and laboratory findings as control group. RESULT Serum MBL levels were found to be low in 17 of 93 infants. Eleven of them were in the sepsis group and six of them were in the control group. Serum MBL levels were significantly lower in infants with sepsis compared with the control group. Frequencies of genotype AB and BB were also significantly higher in the study group compared with the control group. Most importantly, presence of B allele of MBL exon 1 gene was found to be associated with an increased risk for neonatal sepsis. Additionally, in the study group, the mean serum MBL levels were found to be significantly lower in the premature infants compared with the term infants. Pneumonia, bronchopulmonary dysplasia (BPD) and intraventricular hemorrhage (IVH) were significantly higher in infants with MBL deficiency compared with infants with normal MBL levels. CONCLUSION Low MBL levels and presence of B allele of MBL exon 1 gene were found to be important risk factors for development of both neonatal sepsis and pneumonia, especially in premature infants. Low MBL levels and MBL gene polymorphisms might also be associated with inflammation-related neonatal morbidities such as BPD and IVH.
