Abstract
BACKGROUND Canine parvoviral enteritis (CPE) is a fatal disease worldwide. The treatment of CPE is based mainly on supportive and symptomatic treatment. Antiviral addition to the treatment may result in a higher survival. OBJECTIVES This study evaluated the effects of antiviral treatments with a standardized treatment (ST) on the clinical and inflammatory response of dogs with naturally occurring CPE. METHODS Twenty-eight dogs with CPE caused by canine parvovirus type 2 were divided randomly into treatment groups. The ST group received fluid, antibiotic, antiemetic, and deworming treatments. The antiviral treatment groups received the same ST with an additional antiviral drug, recombinant feline interferon omega (rFeIFN-ω), oseltamivir (OSEL) or famciclovir (FAM). RESULTS Compared to the healthy control, the tumor necrosis factor-α, interleukin-1β, interferon (IFN)-α, IFN-γ, haptoglobin, and C-reactive protein values were high (p < 0.05) on day zero. At presentation, mild lymphopenia, neutropenia, and a high neutrophil to lymphocyte (LYM) ratio (NLR) were also observed. Adding rFeIFN-ω to the ST produced the best improvement in the clinical score with a decreased NLR, while leucocytes remained low and inflammatory markers stayed high on day three. The survival rates of the groups were 85.7% in ST+IFN, 71.4% in ST+OSEL, 71.4% in ST+FAM, and 57.1% in ST groups on day seven. CONCLUSIONS Antiviral drugs may be valuable in treating CPE to improve the clinical signs and survival. In addition, the decrease in NLR in favor of LYM may be an indicator of the early prognosis before the improvement of leukocytes, cytokines, and acute phase proteins in CPE.

Abstract
OBJECTIVE The aim of this study was to evaluate the performance of the Charlson Comorbidity Index ≥2, in-hospital onset, albumin <2.5 g/dL, altered mental status, Eastern Cooperative Oncology Group performance status ≥2, steroid use score in predicting mortality in patients with nonvariceal upper gastrointestinal bleeding and compare it with the Glasgow-Blatchford score; the albumin, international normalized ratio; alteration in mental status, systolic blood pressure, and age 65 score; the age, blood tests, and comorbidities score; and Complete Rockall score. METHODS The data of patients with acute upper gastrointestinal bleeding who visited the emergency department during the study period were obtained from the hospital automation system by using the classification of disease codes and analyzed in this retrospective study. Adult patients with endoscopically confirmed nonvariceal upper gastrointestinal bleeding were included in the study. Patients with bleeding from the tumor, bleeding after endoscopic resection, or missing data were excluded. The prediction accuracy of the Charlson Comorbidity Index ≥ 2, in-hospital onset, albumin < 2.5 g/dL, altered mental status, Eastern Cooperative Oncology Group performance status ≥ 2, steroid use score was calculated using the area under the receiver operating characteristic curve and compared with that of Glasgow-Blatchford score, the albumin, international normalized ratio; alteration in mental status, systolic blood pressure, and age 65 score, the age, blood tests, and comorbidities score, and Complete Rockall score. RESULTS A total of 805 patients were included in the study, and the in-hospital mortality rate was 6.6%. The performance of the Charlson Comorbidity Index ≥ 2, in-hospital onset, albumin < 2.5 g/dL, altered mental status, Eastern Cooperative Oncology Group performance status ≥ 2, steroid use score (area under the receiver operating characteristic curve 0.812, 95%CI 0.783-0.839) was better than Glasgow-Blatchford score (area under the receiver operating characteristic curve 0.683, 95%CI 0.650-0.713, p=0.008), and similar to the the age, blood tests, and comorbidities score (area under the receiver operating characteristic curve 0.829, 95%CI 0.801-0.854, p=0.563), the albumin, international normalized ratio; alteration in mental status, systolic blood pressure, and age 65 score (area under the receiver operating characteristic curve 0.794, 95%CI 0.764-0.821, p=0.672), and Complete Rockall score (area under the receiver operating characteristic curve 0.761, 95%CI 0.730-0.790, p=0.106). CONCLUSION The performance of the Charlson Comorbidity Index ≥ 2, in-hospital onset, albumin < 2.5 g/dL, altered mental status, Eastern Cooperative Oncology Group performance status ≥ 2, steroid use score in predicting in-hospital mortality for our study population is better than Glasgow-Blatchford score and similar to the the age, blood tests, and comorbidities score, the albumin, international normalized ratio; alteration in mental status, systolic blood pressure, and age 65 score, and Complete Rockall score.

Abstract
OBJECTIVE This study aimed to show the relationship between low creatinine level and mortality in the internal Intensive Care Unit (ICU) based on the view that there may be a relationship between low creatinine level and mortality in patients admitted to the ICU. PATIENTS AND METHODS This retrospective, single center study was performed in the ICU. Patients older than 18 years who stayed in the ICU for more than 24 hours were included in the study. Patients were evaluated for age, gender, albumin, creatinine levels and length of hospital stay in the analysis. Patients were divided into 7 groups according to serum creatinine levels: group 1: creatinine ≤ 0.4; group 2: 0.4 < creatinine ≤ 0.6; group 3: 0.6 < creatinine ≤ 0.8; group 4: 0.8 < creatinine ≤ 1.0; group 5: 1.0 < creatinine ≤ 1.2; group 6: 1.2 < creatinine ≤ 1.4; group 7: creatinine > 1.4 mg/dL. Creatinine level of 0.7-0.8 mg/dL was considered as reference and cox regression analysis was performed. RESULTS Of 2,359 patients admitted to the ICU, 699 died (29.6%). Mortality relationship according to the accepted creatinine levels of the patients showed a U-shaped distribution, and ICU mortality increased in both low and high creatinine levels. At low creatinine levels (creatinine ≤ 0.4 mg/dl), the mortality rate was 71.4% for men and 10.7% for female (p < 0.001). Cox regression analysis showed that group 1 and group 2 increased mortality (HR: 0.721, 95% CI; 0.555-0.936, HR: 0.509, 95% CI; 0.285-0.909, respectively). CONCLUSIONS In patients admitted to ICU, lower creatinine acceptance is associated with increased ICU mortality and reduced survival.

Abstract
In Turkish cuisine, ready–to–eat vegetable salads (REVS) served with pide/lahmacun, kebab types, and tantuni from animal source in meat restaurants were evaluated since they have the potential to carry risks in terms of Public Health. The microbiological properties of REVS were investigated using agar plate method. Antimicrobial resistance of foodborne pathogens including Escherichia coli and Staphylococcus aureus was tested using Kirby–Bauer disc diffusion method. Moreover, the presence of important enteric viruses was detected by Polymerase Chain Reaction (PCR). The number of total aerobic bacteria, coliform bacteria, yeast and molds and, Staphylococcus and Micrococcus spp. ranged from less than 1 to 6.40, 1 to 6.26, less than 1–5.82 and less than 1–5.66 log10 colony forming units·grams-1 (CFU·g–1) in REVS samples, respectively. None of the REVS tested in this study contained Salmonella spp., whereas E. coli and S. aureus were isolated in 38.1% (16/42) and 2.4% (1/42), respectively. S. aureus was resistant to gentamicin, kanamycin, aztreonam, and ciprofloxacin in the disc diffusion assay, however, it was not harboring the mecA gene. E. coli strains (n=16) were resistant (100%) to aminoglycoside antibiotics and 35.7% (6/16) of the isolates were extended spectrum beta lactamase (ESBL) producing. blaTEM and blaCTXM8/25 were detected in two isolates, whereas one isolate carried blaCTXM–1 and blaTEM together by PCR. Of the REVS, two were evaluated as positive for rotavirus (4.8%), six for hepatitis A (14%), and hepatitis E virus (14%). These results indicate the high microorganism load, presence of ESBL E. coli, and viral enteric pathogens in REVS, hence it is important to perform routine hygiene practices.

Abstract
OBJECTIVE To identify which Machine Learning (ML) algorithms are the most successful in predicting and diagnosing breast cancer according to accuracy rates. METHODS The "College of Wisconsin Breast Cancer Dataset", which consists of 569 data and 30 features, was classified using Support Vector Machine (SVM), Naive Bayes (NB), Random Forest (RF), Decision Tree (DT), K-Nearest Neighbor (KNN), Logistic Regression (LR), Multilayer Perceptron (MLP), Linear Discriminant Analysis (LDA), XgBoost (XGB), Ada-Boost (ABC) and Gradient Boosting (GBC) ML algorithms. Before the classification process, the dataset was preprocessed. Sensitivity, accuracy, and definiteness metrics were used to measure the success of the methods. RESULT Compared to other ML algorithms used in the study, the GBC ML algorithm was found to be the most successful method in the classification of tumors with an accuracy of 99.12%. The XGB ML algorithm was found to be the lowest method with an accuracy rate of 88.10%. In addition, it was determined that the general accuracy rates of the 11 ML algorithms used in the study varied between 88-95%. CONCLUSION When the results obtained from the ML classifiers used in the study are evaluated, the efficiency of the GBC algorithm in the classification of tumors is obvious. It can be said that the success rates obtained from 11 different ML algorithms used in the study are valuable in terms of being used to predict different cancer types.

Abstract
Background The COVID-19 pandemic has profoundly affected the habits of patients, as well as its negative effects on human health. The aim of this study is to investigate the factors associated with discharge against medical advice (DAMA) from the emergency department (ED) during the COVID-19 pandemic. Methods We conducted a retrospective study of the charts of DAMA cases (pandemic group) between May 1 and October 30, 2021 in a tertiary hospital in Istanbul, Turkey. Our data were compared with DAMA cases between May 1 and October 30, 2019 (pre-pandemic group-control group). Results During the pandemic period, DAMA cases increased by 24.5% in the ED compared to the previous period. Compared to the pre-COVID-19 period, among DAMA cases during the COVID-19 period, the rate of those arriving by ambulance (10.9 vs. 18.8%), those with one or more comorbid diseases (8.9 vs. 18.4%), those with a high triage level (4.0 vs. 7.4%), those with health tourism or refugee/asylum insurance (2.9 vs. 6.1%), those with trauma (11.5 vs. 19.9%) or alcohol/drug abuse (2.7 vs. 4.0%) increased significantly (p < 0.001). It was observed that DAMA cases' waiting times for total ED and from the door to doctor decreased during the pandemic period compared to the pre-pandemic period. Conclusion During the COVID-19 pandemic period, it was observed that the rate of those with severe disease increased among DAMA cases. Necessary precautions should be taken for all patients, especially seriously ill patients, to feel safe in the hospital and to be treated, and the negative consequences that may develop should be prevented by addressing the concerns of the patients and their relatives.

Abstract
Aim In this study, we aimed to investigate the effects of Ultrasonic Coagulation (UC), Bipolar Energy Sealing System (BESS), Intra Operative Nerve Monitoring (IONM) and surgical experience on the complications of thyroid surgery. Method The data of 1627 patients who underwent thyroid surgery for various indications in our department between 2009 and 2018 were analyzed retrospectively and the effects of different technological devices on complications were investigated. Results Transient recurrent laryngeal nerve (RLN) palsy was higher between 2009 and 2013, when IONM was not in routine use (p=0.029). There were no significant differences between two energy devices (UC and BESS) in terms of transient or permanent RLN palsy, bleeding, and transient or permanent hypocalcemia. Multivariate analysis showed that young age (0.006), female gender (0.016), surgery type (p<0.001), and lateral neck dissection (p=0.026) are independent risk factors for transient hypocalcemia. Conclusion The results indicate that there is no superior hemostatic device. IONM and specific branching decrease transient RLN palsy. Female gender, young age, completion thyroidectomy, and lateral neck dissection were independent risk factors for the development of transient hypocalcemia.

Abstract
Aims To investigate the root canal anatomy and the incidence of fused roots in maxillary first molar (MFM) and maxillary second molar (MSM) teeth in the Turkish population and compare them to teeth with separate roots using cone-beam computed tomography (CBCT). Methods CBCT images of 616 MFMs and 703 MSMs were analyzed from 402 patients for the number of roots and the presence of fusion. The canal configuration of teeth with separate and fused roots was compared. Type of fusion and canal merging positions were determined. A P value of less than 0.05 was considered significant. Results Five hundred and seventy-one (92.69%) MFMs had three separate roots, one (0.16%) had four roots and the incidence of root fusion was 7.14%. An additional mesiobuccal (MB) canal was present in 79.34% of the teeth with three separate roots. There was no merging of canals in 36 of 44 teeth with fused roots. The prevalence of fusion was higher in the MSMs (23.47%). The incidence of three and four separate roots in MSM teeth was 74.68% and 1.85%, respectively. The prevalence of additional MB canals in teeth with three separate roots was 53.14%. There was no canal merging in 60% of the fused rooted teeth. There were two-merged canals in 31.52% and multiple merged canals in 8.48% of the MSMs. Conclusions In the Turkish population, the incidence of root fusion in the MFMs and MSMs was 7.14% and 23.47%, respectively, with more canal merging in the MSMs.

Abstract
Covid-19 pandemic is spreading rapidly in Turkey. We aimed to examine the numbers and demographic data of patients who applied to the general surgery outpatient clinics and operated in this process. Our primary outcome is to reveal the response of general surgery patients to the Covid-19 pandemic.The first Covid-19 case in Turkey has appeared in March 11, 2020. Patients who were operated on due to a surgical emergency or trauma were evaluated separately. Patients in 3 periods were compared with each other. A total of 12728 patients were examined in general surgery outpatient clinics in 26 working days. It is seen that patients come to the outpatient clinic after the first time the Covid-19 patient is seen. All patients reduced hospitalization after the first death due to Covid-19. Women had reduced going to the hospital earlier than men. There was no change in the number of emergency surgeries. Rapid decrease was observed in the number of elective surgeries.It is not easy to control the entrance and exit of these busy hospitals. The remote diagnosis (mail, phone or video-call) and treatment methods that can be expected in the near future may be even closer with the Corona virus (Tab. 3, Fig. 4, Ref. 15). Keywords: general surgery, Covid-19, outpatient clinics, operation, reaction of patients.

Abstract
Aim: The objective of this study was to evaluate the possible protective effects of probiotic bacteria, especially Bifidobacterium and Lactobacillus strains, on 4,4'-dichlorodiphenyltrichloroethane (DDT)-induced toxicity. For this reason, we evaluated the relationship between probiotics and toxicity by checking immunological and immunohistochemical parameters. Materials & methods: Probiotic pretreatment was applied to 36 Wistar albino rats for 12 consecutive days. Serum aspartate aminotransferase and alanine aminotransferase levels were detected. CD3 and NF-κB staining methods were then performed by immunohistochemistry. Finally, pro- and anti-inflammatory cytokines were measured by ELISA. Results: DDT caused a serious increase/decrease in some cytokine parameters. The effective dose was 1 × 1011 colony-forming unit probiotic treatment. CD3 and NF-κB positivity were intense in DDT group whereas the intensity was reduced in probiotic treatment groups. Discussion: The probiotic mixture has a potential to prevent inflammatory and oxidative stress related organ injuries. Further studies should be performed to explain the possible mechanisms.

Abstract
Aim: The objective was to investigate the genotypic relationship of S and M segments in Crimean-Congo hemorrhagic fever virus (CCHFV) by phylogenetic analysis in 25 patients from seven endemic cities in Turkey. Materials & methods: A total of 25 samples from patients with CCHF were included between 2012 and 2015. Phylogenetic tree analyses were inferred using MEGA version-6.0 and distances were calculated by Kimura’s 2-parameter. Results: Phylogenetic analysis showed that all isolated viruses (n = 25) were in the predicted clades such as clade V- Europe-1 regarding both S and M segments of the CCHFV. Conclusion: Further epidemiological, molecular and phylogenic studies should be performed in both reservoir animals/vectors and humans to determine the incidence of tick-borne infectious disease and to help to develop vaccines for prevention of the disease.

Abstract
BACKGROUND Viral gastroenteritides are among the causes of higher morbidity and mortality in the childhood period, especially in infants. Although viral-induced diarrheal diseases are important problems in Erzurum, there have been no studies on the molecular prevalence of viral gastroenteritis agents in this region's children. The aim of the prospective study is to determine the molecular prevalence of the most commonly seen viral etiologic agents and their coinfection rates in children under 5 years of age with gastroenteritis in Erzurum, Turkey. METHODS Stool samples from 375 children between 0 and 5 years of age who suffered from acute diarrhea were investigated for the presence of Rotavirus, Norovirus, Astrovirus and Adenovirus by reverse transcriptase polymerase chain reaction, followed by conventional PCR techniques. The presence of Rotavirus, Norovirus, Astrovirus and Adenovirus in the specimens was detected by amplification of the VP6, RdRp, ORF-1b and Hexon regions, respectively. Stool samples were also investigated non-viral enteropathogens by conventional techniques. RESULTS At least one viral pathogen was detected in 59.2% of the stool samples. Rotavirus was the most frequently observed agent (32.3%), followed by Norovirus (20.3%), Adenovirus (9.6%) and Astrovirus (5.6%). All specimens were negative for bacterial pathogens. Twenty seven (7.2%) specimens were positive for intestinal helminths and protozoan. A total of 39 coinfection (10.4%) including 38 dual and 1 triple were detected. The most frequent coinfections were observed between Norovirus plus Rotavirus and Norovirus plus Adenovirus. CONCLUSIONS Single infections or coinfections of the enteropathogenic viruses occur at a significant rate in Erzurum's children. This study draws attention to the necessity of taking account of multiple viral infections in studies on combined vaccines and the treatment of gastroenteritis.

Abstract
Objective Crimean-Congo hemorrhagic fever (CCHF) is an acute and highly fatal disease. In this study, our aim was to compare and evaluate the prevalence of CCHF virus (CCHFV) antibody among occupational high-risk groups by using the enzyme-linked immunosorbent assay and draw attention to the occupational groups that are at high risk for CCHF infection in an endemic region for this zoonotic infection in Erzurum, Turkey. Materials and Methods The antibody levels against CCHFV were surveyed among slaughterhouse workers, animal breeders, and veterinarians. The study population was composed of 72 participants having direct contact with animals and 19 blood donors who were not in direct contact with animals. Results The overall rate of CCHF immunoglobulin G positivity in risk groups was found to be 6.94% (5/72). CCHFV antibodies were found in 4 (12.5%) individuals of the animal breeder group. This ratio was considered significantly higher compared with the healthy control group. CCHFV antibodies were found in only one person (4.0%) who was an abattoir worker. In the veterinarian group, all people were found negative. Conclusion In our study, the variables showing important associations with the prevalence of anti-CCHFV antibodies were livestock breeding, rural areas, and age. It was concluded that our region is endemic with regard to CCHF infection and persons who had direct contact with animals are at high risk. Thus, these participants must take necessary measures to protect themselves from CCHF and should be trained by health authorities.

Abstract
Parvovirus B19 (B19V) is one of the major viral pathogens that infect only human beings. This study's aim is to determine which genotypes of the B19V are present in Turkey and to perform a phylogenetic analysis. Twelve B19V positive serum specimens already diagnosed by real-time PCR amplifying a partial region of the NS gene were included in this study. The serological markers and viral loads of the patients were determined. The positivity of the specimens was confirmed using semi-nested PCR. To determine the genotype of the B19V, PCR-positive amplicons were sequenced directly and compared to GenBank-referenced strain sequences. The phylogeny of the 12 sequenced strains was constructed with the maximum likelihood method. Two different genotypes of B19V were identified in our study. Genotype 2 of B19V was not detected. All of the B19V genotype 1 sequences were clustered in the common genotype 1a cluster (10/12, 83.3%). The average quantification of the B19V strains was determined to be 2.1 × 107 IU/ml. The nucleotide identities between our strains and those isolated in other countries were 85.8%-99.5%. Compared to the Turkish strains identified in our study, at the nucleotide level, the closest strains based on genotypes 3b and 1a were the Germany and Netherlands isolates respectively. This study was the first to provide the genotypic variation of B19V circulated in Turkey. We determined two distinct subtypes of B19V, including subtype 3b and 1a. While the genotype 1 is common all over the world, genotype 3 has begun to spread outside of Africa.

Abstract
Testicular metastasis is rare with the prostate being the most common site of primary cancer. We report a case of a 72-year-old man with castration-resistant prostate cancer (CRPC) and known metastases to bone and lymph nodes, who developed bilateral painful swollen testes 3 years after the initial diagnosis of prostate cancer. He had first presented with lower urinary tract symptoms (LUTS) with suspicious findings on digital rectal examination of the prostate, and an elevated serum prostate specific antigen (PSA) level of 129 ng/mL. Transrectal prostate biopsy revealed Gleason 4 + 5 adenocarcinoma. Radiological staging showed locally advanced prostate cancer with extensive metastases to bone and pelvic and retroperitoneal lymph nodes. He was given hormonal therapy for over 2 years until progression to CRPC. Six months later he developed painful bilateral testicular swellings, and serum markers for testicular germ cell cancer were normal. Bilateral orchiectomy was performed, showing metastatic prostate cancer (Gleason 4 + 5) on histology. One month postoperatively his PSA level dropped to 0.1 ng/mL from a presurgery level of 6.24 ng/mL.

Abstract
Femoral artery pseudoaneurysms are commonly iatrogenic due to increasing use of the artery for arterial interventions. Other reasons of pseudoaneurysm formation are intravenous drug use and penetrating trauma. Here, we have discussed the management strategy of a femoral artery pseuodoaneursym and the modalities for preventing the misdiagnoses of the pseudoaneurysm in the emergency department. A 50-year-old male patient was referred to our emergency department (ED) with claudication and severe local swelling. Ten days earlier, he had been referred to another ED immediately after a gunshot injury to the left inguinal zone. Duplex ultrasound and CT angiography of the left lower extremity revealed a 4 cm sac of pseudoaneurysm on the distal part of posterofemoral branch of deep femoral artery and a 9*10 cm haematoma on the posteromedial part of pseudoaneurysm. The patient underwent open repair surgery due to co-existing large haematoma and risk of infection. The patient was discharged after three days hospitalization. Pain, extremity oedema, pulsatile mass, femoral bruit, palpable thrill, and compressive neuropathy should alert the physician to possible femoral artery pseudoaneurysm. Duplex ultrasound and CT angiography are important diagnostic steps to reveal a possible life-threatening vascular injury.

Abstract
Objective Active surveillance (AS) offers a strategy to reduce overtreatment and now is a widely accepted treatment option for low-risk prostate cancer. An ideal tool for risk-stratification would detect aggressive cancers and exclude such men from taking up AS in the first place. We evaluate if a combination of transperineal template biopsy with magnetic resonance imaging (MRI)-targeted biopsy identifies significant prostate cancer amongst men initially diagnosed with low-risk prostate cancer. Methods This prospective, single-blinded study included men with low-risk prostate cancer (D'Amico's Criteria) diagnosed on conventional transrectal ultrasound-guided biopsy. Patients first underwent multiparametric MRI of the prostate ≥6 weeks after initial biopsy. Each suspicious lesion is mapped and assigned a Prostate Imaging Reporting and Data System (PIRADS) score. Template biopsy is first performed with the surgeon blinded to MRI findings followed by MRI-targeted biopsy using a robotic transperineal biopsy platform. Results The age of the 19 men included is 65.4 ± 4.9 years (mean ± SD). Prostate specific antigen (PSA) at diagnosis and at the time of transperineal biopsy were comparable (7.3 ± 1.7 ng/mL and 7.0 ± 1.8 ng/mL, p = 0.67), so were prostate volumes (34.2 ± 8.9 mL and 32.1 ± 13.4 mL, p = 0.28). MRI-targeted biopsy had a higher percentage of cancer detection per core compared to template biopsy (11.7% vs. 6.5%, p = 0.02), this was more than 3 times superior for Gleason 7 disease (5.9% vs. 1.6%, p < 0.01). Four of 18 (22.2%) patients with MRI lesions had significant disease with MRI-targeted biopsy alone. Three of 19 patients (15.8%) had significant disease with template biopsy alone. In combination, both techniques upclassified five patients (26.3%), all of whom underwent radical prostatectomy. Whole mount histology confirmed tumour location and grade. All six patients with PIRADS 5 lesions had cancer detected (66.6% significant disease). Conclusion A combination of MRI-targeted and template biopsy may optimally risk-classify “low-risk” patients diagnosed on initial conventional transrectal ultrasonography (TRUS) prostate biopsy.

Abstract
BACKGROUND/AIM There are limited studies on genotyping and phylogenetic analysis of norovirus in Turkey, and this has not previously been studied in the Eastern Anatolia region. The aim of the present study was to determine the norovirus profile in this region with genotyping and phylogenetic analysis. MATERIALS AND METHODS Included in the study were stool samples obtained from 427 people from different age groups in Eastern Anatolia. The nucleic acid samples isolated by the automatic system and nucleic acid sequence reactions and phylogenetic analyses were performed on RNA samples. RESULTS The presence of norovirus was detected in 86 (20.1%) of the 427 stool samples by RT-PCR analysis. Twenty-six samples selected randomly from norovirus-RNA positive samples were subjected to the sequence reaction. In 24 of the 26 samples, genogroup GII was determined, as well as one each from GI and GIV in sequence reactions. Four different genotypes were detected in genogroup GII, which were determined to be the dominant types. These were GII.1, GII.4, GII.16, and GII.21. The GI.6 and GIV.1 genotypes were determined in genogroups GI and GIV, respectively. CONCLUSION The high frequency and genetic diversity of these infections are risk factors for disease and so vaccine studies should be undertaken in consideration of this situation.

Abstract
We evaluated the free fatty acids differences in plasma between hyperemesis gravidarum(HG) and healthy pregnant in first trimester pregnancy. OBJECTIVE We aimed to compare the plasma levels of DHA, AA and EPA, between HG patients and healthy pregnant women. DESIGN Fifty-two pregnants were involved in the study. Twenty-six pregnants of them were HG as study group, and twenty-six pregnants were enrolled as healthy pregnant women at the similar gestational age. The saturated fatty acids C14, C15, C16, C18, C20, C22, and C24; the omega-3 fatty acids eicosapentaenoic acid, (EPA) and docosahexaenoic acid, (DHA); the omega-6 fatty acids linoleic acid, arachidonic acid (AA), and homo-gamma-linolenic acid; and the omega-9 fatty acids oleic acid, erucic acid, and nervonic acid were analysed by gas chromatography. RESULTS Statistically differences was not seen between the groups with maternal age, gestational age, or plasma levels of EPA, DHA, and AA. Statistically significant difference was seen between the groups with plasma levels of C20 and C22(p<0.05). C20 was declined but C22 was rised in the HG patients. CONCLUSION EPA, DHA, or AA, which related to placental and fetal neural development are not changing from Hyperemesis gravidarum.

Abstract
Ketamine is a short-acting anaesthetic agent that has gained popularity as a 'club drug' due to its hallucinogenic effects. Substance abuse should be considered in young adult patients who present with severe debilitating symptoms such as lower urinary tract symptoms, even though the use of controlled substances is rare in Singapore. Although the natural history of disease varies from person to person, a relationship between symptom severity and frequency/dosage of abuse has been established. It is important to be aware of this condition and have a high degree of clinical suspicion to enable early diagnosis and immediate initiation of multidisciplinary and holistic treatment. A delayed diagnosis can lead to irreversible pathological changes and increased morbidity among ketamine abusers.

Abstract
Aim: Our aim was to investigate the prevalence of hepatitis E virus (HEV) and its potential zoonotic role in occupational groups that come into direct contact with domestic ruminants and chickens. Materials & methods: The seroprevalence of the HEV IgG antibody was determined on 92 samples using a commercial ELISA test kit. Results: The overall rate of HEV-IgG seroprevalence in the risk group was 35.9%. The control group seroprevalence was found to be 4.4%. Conclusion: HEV infection is a potential occupational hazard for people who work in jobs directly related to animals, with the exception of veterinarians, who use protective equipments to prevent the infection. Further studies should be performed with increased observation of specific risk groups in order to understand the local epidemiology and guide vaccination strategies.

Abstract
BACKGROUND Probiotics are "live", beneficial microbes that provide important health benefits in their hosts. There is significant interest in the modulation and regulation of the immune function by probiotics. OBJECTIVE To investigate the immunomodulatory effects of a probiotic mixture, including Lactobacillus and Bifidobacterium species, by detecting serum cytokine and immunoglobulin levels. METHODS The rats were randomly divided into 4 groups. The first group was "Control group" and other 3 groups were probiotic application groups who received different doses of probiotics. The probiotic mixture included 12 probiotic bacteria, mostly Lactobacillus and Bifidobacterium strains. Probiotic mixture was administered to rats for 12 consecutive days. TNF-α, TGF-β, IL-1-β, IL-6, and IL-10 levels as well as serum IgG and IgA concentrations were detected in the sera after 12 days. RESULTS Probiotics led to a decrease in the levels of TNF-α, IL-6 and TGF-β; however, they led to increase in the serum levels of IL-10, IgG and IgA. There were significant differences between control group and probiotic application groups (p<0.05). CONCLUSION These data suggest that the commensal microbiota are important for stimulating both proinflammatory and regulatory responses in order to rapidly clear infections and minimize inflammation-associated tissue damage.

Abstract
OBJECTIVES In the present study, our aim was to investigate the possible protective effects of epigallocatechin gallate (EGCG) on lipopolysaccharide (LPS)-induced hepatotoxicity by using Hep3B human hepatoma cells. Specifically, the study examines the role of some proinflammatory markers and oxidative damage as possible mechanisms of LPS-associated cytotoxicity. Consequently, the hepatocellular carcinoma cell line Hep3B was chosen as a model for investigation of LPS toxicity and the effect of EGCG on LPS-exposed cells. MATERIALS AND METHODS The Hep3B human hepatoma cells were used for this study. The cytotoxic effects of chemicals (EGCG and LPS), AST and ALT levels, SOD and CAT activities, GSH-Px level and TNF-alpha and IL-6 levels were detected by using different biochemical and molecular methods. LPS and EGCG were applied to cells at various times and doses. RESULTS The highest treatment dose of EGCG (400 µM) led to a dramatic decrease in SOD level and increase in CAT and GSH levels. Additionally, the highest dose of EGCG also led to a dramatic increase in TNF-alpha and IL-6 levels. On the other hand, effective doses of EGCG (200 and 100 µM) normalized all related parameters levels. CONCLUSION LPS caused hepatotoxicity, but interestingly, a high dose of EGCG was found to be a cytotoxic agent in this study. However, other two doses of EGCG led to a decrease in both inflammatory cytokine levels and antioxidant enzyme levels. Further studies should examine the effect of EGCG on secondary cellular signaling pathways.

Abstract
Partial deletion of the long arm of the chromosome 13, 13q deletion syndrome is a rare chromosomal disorder characterized by severe growth and mental retardation, microcephaly, facial dysmorphism, brain malformations (holoprosencephaly, Dandy-Walker malformation), distal limb defects, eye anomalies, genitourinary and gastrointestinal tract malformations (Hirschsprung's disease). Approximately 1.2 Mb region in 13q32 was suggested as minimal critical region which is responsible for severe mental and growth retardation and brain anomalies. Here we described a male patient with de novo interstitial deletion of 13q31.1-q34 associated with short stature, microcephaly, facial dysmorphism, clinodactyly, cryptorchidism, micropenis, epilepsy, HPE, DWM, and HSCR. According to the literature review, present case indicated that smallest deleted region associated with DWM and HPE might be located at the 13q32.3, limb defects 13q34, anogenital malformations 13q33.3-34, and HSCR 13q31.1-32.1.

Abstract
BACKGROUND Methylenetetrahydrofolate Reductase (MTHFR) polymorphisms by impairing folate metabolism may influence the development of allergic diseases. The results of studies evaluating the relationship between MTHFR polymorphisms and atopic disease are controversial. The aim of this study was to investigate the association between the polymorphisms of C677T and A1298C for MTHFR gene and allergic rhinitis (AR) in children. METHODS Ninety patients followed up with diagnosis of allergic rhinitis in our clinic and 30 children with no allergic diseases were included in the study. All participants were genotyped for the MTHFR (C677T) and (A1298C) polymorphisms. Vitamin b12, folate and homocysteine levels were measured. RESULTS The mean age of patients was 9.2±2.9 years; 66.7% of the patients were male. There was no significant difference between patient and control groups regarding gender, age and atopy history of the family (p>0.05). The frequency of homozygotes for MTHFR C677T polymorphism in the patient and control groups was 3.3% and 10%, respectively. The frequency of homozygotes for MTHFR A1298C polymorphism among groups was 26.7% and 16.7%, respectively. The association between allergic rhinitis and polymorphisms of C677T and A1298C for MTHFR gene was not statistically significant in patients compared with controls (p>0.05). There were no statistically significant differences between the patients and the control group in terms of serum vitamin b12, folate and homocysteine levels (p>0.05). CONCLUSION We found no evidence for an association between allergic rhinitis and polymorphisms of C677T and A1298C for MTHFR gene in children. Further studies investigating the relationship between MTHFR polymorphism and AR are required.

Abstract
A phenomenological and analytical model for the influence of strain effects on atomic transport in columnar thin films is presented. A model system consisting of two types of crystalline thin films with coherent interfaces is assumed. Biaxial mechanical strain ε0 is caused by lattice misfit of the two phases. The conjoined films consist of columnar crystallites with a small diameter l. Strain relaxation by local elastic deformation, parallel to the hetero-interface, is possible along the columnar grain boundaries. The spatial extent δ0 of the strained hetero-interface regions can be calculated, assuming an exponential decay of the deformation-forces. The effect of the strain field on the local ionic transport in a thin film is then calculated by using the thermodynamic relation between (isostatic) pressure and free activation enthalpy ΔG(#). An expression describing the total ionic transport relative to bulk transport of a thin film or a multilayer as a function of the layer thickness is obtained as an integral average over strained and unstrained regions. The expression depends only on known material constants such as Young modulus Y, Poisson ratio ν and activation volume ΔV(#), which can be combined as dimensionless parameters. The model is successfully used to describe own experimental data from conductivity and diffusion studies. In the second part of the paper a comprehensive literature overview of experimental studies on (fast) ion transport in thin films and multilayers along solid-solid hetero-interfaces is presented. By comparing and reviewing the data the observed interface effects can be classified into three groups: (i) transport along interfaces between extrinsic ionic conductors (and insulator), (ii) transport along an open surface of an extrinsic ionic conductor and (iii) transport along interfaces between intrinsic ionic conductors. The observed effects in these groups differ by about five orders of magnitude in a very consistent way. The modified interface transport in group (i) is most probably caused by strain effects, misfit dislocations or disordered transition regions.

Abstract
BACKGROUND The likelihood of tumour recurrence after nephrectomy in localised clear cell renal cell carcinoma is well characterised by clinical and pathological parameters. However, these assessments can be improved and personalised by the addition of molecular characteristics of each patient's tumour. We aimed to develop and validate a prognostic multigene signature to improve prediction of recurrence risk in clear cell renal cell carcinoma. METHODS In the development stage, we investigated the association between expression of 732 genes, measured by reverse-transcription PCR, and clinical outcome in 942 patients with stage I-III clear cell renal cell carcinoma who had undergone a nephrectomy at the Cleveland Clinic (OH, USA). 516 genes were associated with recurrence-free interval. 11 of these genes were selected by further statistical analyses, and were combined with five reference genes (ie, 16 genes in total), from which a recurrence score algorithm was developed. The recurrence score was then validated in an independent cohort of 626 patients from France with stage I-III clear cell renal cell carcinoma who had also undergone nephrectomy. The association between the recurrence score and the risk of recurrence and cancer-specific survival in the first 5 years after surgery was assessed using Cox proportional hazard regression, stratified by tumour stage (stage I vs stage II vs III). FINDINGS In our primary univariate analysis, the continuous recurrence score (median 37, IQR 31-45) was significantly associated with recurrence-free interval (hazard ratio 3·91 [95% CI 2·63-5·79] for a 25-unit increase in score, p<0·0001). In multivariable analyses, the recurrence score was significantly associated with the risk of tumour recurrence (hazard ratio per 25-unit increase in the score 3·37 [95% CI 2·23-5·08], p<0·0001) after stratification by stage and adjustment for tumour size, grade, or Leibovich score. The recurrence score was able to identify a clinically significant number of both high-risk stage I and low-risk stage II-III patients. A heterogeneity study on separate samples showed little to no intratumoural variability among the 16 genes. INTERPRETATION Our findings validate the recurrence score as a predictor of clinical outcome in patients with stage I-III clear cell renal cell carcinoma, providing a more accurate and individualised risk assessment beyond existing clinical and pathological parameters.

Abstract
BACKGROUND Insulin-like growth factor 2 mRNA binding protein 3 (IMP3) is expressed in metastatic and a subset of primary renal cell carcinoma (RCC). However, the role of IMP3 in RCC progression was poorly understood. We aim to uncover the mechanism of IMP3 in regulating clear cell RCC (CCRCC) progression and validate the prognostic significance of IMP3 in localized CCRCC. METHODS Caki-1 cells stably overexpressing IMP3 and Achn cells with knockdown of IMP3 were analyzed for cell migration and invasion by Transwell assay. RNA-seq was used to profile gene expression in IMP3-expressing Caki-1 cells. A cohort of 469 localized CCRCC patients were examined for IMP3 expression by immunohistochemistry using tumor tissue array. RESULTS IMP3 promoted Caki-1 cell migration and invasion, whereas knockdown of IMP3 by RNAi inhibited Achn cell migration and invasion. Enhanced IMP3 expression activated NF-кB pathway and through which, it functioned in promoting the RCC cell migration. IMP3 expression in localized CCRCC was found to be associated with higher nuclear grade, higher T stage, necrosis and sarcomatoid differentiation (p< 0.001). Enhanced IMP3 expression was correlated with shorter recurrence-free and overall survivals. Multivariable analysis validated IMP3 as an independent prognostic factor for localized CCRCC patients. CONCLUSION IMP3 promotes RCC cell migration and invasion by activation of NF-кB pathway. IMP3 is validated to be an independent prognostic marker for localized CCRCC.

Abstract
OBJECTIVE End-stage renal disease (ESRD) patients with acquired cystic kidney disease are at higher risk of developing renal cell carcinoma (RCC) than the general population. The aim of this study was to investigate the clinical and histopathological differences between ESRD patients and the general population with RCC. MATERIALS AND METHODS Data were retrospectively collected from all nephrectomies performed for localized RCC from 2000 to 2010. Age at nephrectomy, gender, race, symptoms, baseline Eastern Cooperative Oncology Group (ECOG) performance status, Charlson Comorbidity Index score and histological data were extracted. Independent-samples t test and Mann-Whitney test were used for quantitative data, while chi-squared (two-sided) and Fisher's exact tests were used for qualitative data. RESULTS This study included 627 patients: 73 with and 554 without ESRD. The majority of patients were Chinese. The male to female ratio of 2:1 was identical in both groups. Baseline ECOG performance status and Charlson Comorbidity score were higher in the ESRD group. RCC in ESRD patients was more frequently asymptomatic (56.2% vs 44.9%, p = 0.071), diagnosed earlier (53.6 ± 11.8 years vs 57.9 ± 12.2 years, p = 0.004) and of lower stage (p < 0.001). The ESRD cohort had a higher proportion of the papillary histological subtype (21.9% vs 9.7%, p < 0.001). Importantly, there was a trend towards more favourable outcomes in ESRD patients in terms of cancer-specific (p = 0.203) and relapse-free survival (p = 0.096). CONCLUSION This study suggests that RCC in ESRD patients is associated with more favourable clinical and histological features and oncological outcome compared with that in patients with normal renal function.

Abstract
The deletion 22q13.3 syndrome (Phelan-McDermid syndrome) is a chromosome microdeletion syndrome characterized by neonatal hypotonia, global developmental delay, normal to accelerated growth, absent to severely delayed speech, and minor dysmorphic features. Common physical traits include long eye lashes, large or unusual ears, relatively large hands, dysplastic toenails, full brow, dolicocephaly, full cheeks, bulbous nose, and pointed chin. Behavior is autisticlike with decreased perception of pain and habitual chewing or mouthing. The loss of 22q13.3 can result from simple deletion, translocation, ring chromosome formation and less common structural changes affecting the long arm of chromosome 22, specifically the region containing the SHANK3 gene. The present case was referred at the age of 8 months because of delayed psychomotor development, hypotonia and autistic features. Clinical examination showed a small forehead, long eyelashes, epicanthal folds and lowset ears, large and broad hands and feet with short terminal phalanges. He had no eye contact and could not sit without support.

Abstract
We report a patient with a rare de novo duplication of 12q23.1-12q24.33 region with a 32.7 Mb gain, having similar features seen in previously reported isolated cases of duplications of the 12q23q24 region, such as growth retardation, neuromotor retardation, corpus callosum agenesis, dysmorphic features such as, hypertelorism, epicanthus, flat nasal bridge, low-set small ears, down-turned corners of the mouth, micrognathia, cryptorchidism and limb anomalies such as pes plano valgus, prominent heels and overriding toes. Our patient has Noonan-like features, such as short stature, short neck, epicanthal folds, ptosis of eyelids, hypertelorism, pectus excavatum, widely spaced nipples and cryptorchidism. Duplication of PTPN11 gene has been postulated as a mechanism for the Noonan syndrome. Phenotypic features and the genes involved in this region are important to further delineate the 12q23q24 phenotype.

Abstract
Hypopituitarism in adult life is commonly acquired and the main causes are known as pituitary tumors and/or their treatments. Since there are new insights into the etiology of hypopituitarism and presence of differences in various populations, more studies regarding causes of hypopituitarism are needed to be done in different ethnic groups with sufficient number of patients. Therefore, we performed a multi-center database study in Turkish population investigating the etiology of hypopituitarism in 773 patients in tertiary care institutions. The study was designed and coordinated by the Pituitary Study Group of SEMT (The Society of Endocrinology and Metabolism of Turkey). Nineteen tertiary reference centers (14 university hospitals and 5 training hospitals) from the different regions of Turkey participated in the study. It is a cross-sectional database study, and the data were recorded for 18 months. We mainly classified the causes of hypopituitarism as pituitary tumors (due to direct effects of the pituitary tumors and/or their treatments), extra-pituitary tumors and non-tumoral causes. Mean age of 773 patients (49.8 % male, 50.2 % female) was 43.9 ± 16.1 years (range 16-84 years). The most common etiology of pituitary dysfunction was due to non-tumoral causes (49.2 %) among all patients. However, when we analyze the causes according to gender, the most common etiology in males was pituitary tumors, but the most common etiology in females was non-tumoral causes. According to the subgroup analysis of the causes of hypopituitarism in all patients, the most common four causes of hypopituitarism which have frequencies over 10 % were as follows: non-secretory pituitary adenomas, Sheehan's syndrome, lactotroph adenomas and idiopathic. With regard to the type of hormonal deficiencies; FSH/LH deficiency was the most common hormonal deficit (84.9 % of the patients). In 33.8 % of the patients, 4 anterior pituitary hormone deficiencies (FSH/LH, ACTH, TSH, and GH) were present. Among all patients, the most frequent cause of hypopituitarism was non-secretory pituitary adenomas. However, in female patients, present study clearly demonstrates that Sheehan's syndrome is still one of the most important causes of hypopituitarism in Turkish population. Further, population-based prospective studies need to be done to understand the prevalence and incidence of the causes of hypopituitarism in different countries.
