Abstract
BACKGROUND Infections by protozoans of the genus Giardia are a common cause of diarrhea in dogs. Canine giardiosis constitutes a disease with a zoonotic potential; however, it is often underestimated due to its challenging diagnosis. The objective of the study was to assess the diagnostic performance of an immunochromatographic strip test (SpeedTM Giardia, Virbac, France) comparing it with microscopy (zinc sulfate flotation) by utilizing the combination of an enzyme immunoassay (ProSpecTTM Giardia EZ Microplate Assay, Oxoid Ltd., UK) and the PCR as the gold standard. A positive result in both ELISA and PCR was set as the gold standard. METHODS Initially, fecal samples from dogs with clinical signs compatible with giardiosis were tested with the SpeedTM Giardia test and separated into two groups of 50 samples each: group A (positive) and group B (negative). Thereafter, all samples were examined by zinc sulfate centrifugal flotation technique and assayed by the ProSpecTTM Giardia Microplate Assay and PCR. The performance of the SpeedTM Giardia and zinc sulfate centrifugal flotation tests were calculated estimating sensitivity, specificity, and positive and negative likelihood ratio; the chi-square and McNemar tests were used for the comparison of the two methods. RESULTS Giardia cysts were not detected by microscopy in 16 out of the 50 samples (32%) of group A and in none of group B samples. Eight out of 50 samples in group B (16%) were tested positive both with the ProSpecTTM Giardia Microplate Assay and PCR. Fecal examination with the SpeedTM Giardia test was more sensitive (86.2%) than the parasitological method (58.6%, P < 0.001) while the specificity of both methods was 100%. CONCLUSIONS The SpeedTM Giardia test is an easy-to-perform diagnostic method for the detection of Giardia spp., which can increase laboratory efficiency by reducing time and cost and decrease underdiagnosis of Giardia spp. infections. This immunochromatographic strip test may be routinely exploited when a rapid and reliable diagnosis is required, other diagnostic techniques are unavailable and microscopy expertise is inefficient. In negative dogs with compatible clinical signs of giardiosis, it is recommended either to repeat the exam or proceed with further ELISA and PCR testing.

Abstract
The poultry red mite (Dermanyssus gallinae), an obligatory blood feeding ectoparasite, is primarily associated with laying hens where it is estimated to cause losses of ~€231 million per annum to European farmers. Moderate to high infestation levels result in negative impacts on hen welfare, including increased cannibalism, irritation, feather pecking, restlessness, anemia, and mortality. Acaricides are currently the prevailing method of population control for D. gallinae, although resistance against some classes of acaricide has been widely reported. The development of resistance highlights a growing need for research into alternative control methods, including the development of a suitable and effective vaccine. Understanding the genetic structure of D. gallinae populations can support improved management of acaricide resistance and sustainability of future vaccines, but limited data are currently available. The aim of this study was to characterize D. gallinae isolates from Europe, targeting the cytochrome c oxidase subunit 1 (COI) gene to gain an insight into population structure and genetic diversity of currently circulating mites. Dermanyssus gallinae isolates were collected from Albania, Belgium, Croatia, Czech Republic, Denmark, France, Greece, Italy, the Netherlands, Portugal, Romania, Slovenia, Turkey and the United Kingdom. Genomic DNA was extracted from individual adult D. gallinae mites and a 681bp fragment of the COI gene was amplified and sequenced. Phylogenetic analyses of 195 COI sequences confirmed the presence of multiple lineages across Europe with 76 distinct haplotypes split across three main haplogroups and six sub-haplogroups. Importantly there is considerable inter- and intra-country variation across Europe, which could result from the movement of poultry or transfer of contaminated equipment and/or materials and husbandry practices.

Abstract
Filarioids of the genus Cercopithifilaria (Spirurida, Onchocercidae) are parasites of wild and domestic animals in tropical and subtropical regions being transmitted by ixodid ticks. Though this filarioid species have been studied in canine and tick populations in Europe, data on their species diversity and geographical distribution in Greece is scant. Thus, the aims of this study were to investigate the presence of Cercopithifilaria spp. in dogs and ticks across Greece and to assess the possible risk factors. A total of 500 skin biopsies were collected from dogs, while 508 ticks were collected from 180 infested animals and examined. Sediments from skin biopsies were microscopically screened for detection of dermal microfilaria (mfs). Skin samples (n = 115) and tick specimens (n = 153) were molecularly subjected by PCR. Overall, 70 samples (14%) scored positive for mfs. Specifically, 68 samples (13.6%) were positive for Cercopithifilaria bainae and two (0.4%) were co-infected with C. bainae and Cercopithifilaria sp. II. Molecular analyses revealed that all sequences obtained belong to C. bainae. Haplotype I was the most frequent (92.6%), followed by haplotype XVIII (3%) and haplotypes II and IX (1.5%). Three new haplotypes of C. bainae, named XIX, XX, and XXI, were also identified. Among the risk factors examined, habitat, dog use, body weight, tick infestation history, and the use of acaricides were associated with the presence of C. bainae. The estimated prevalence of Cercopithifilaria spp. demonstrates that these filarioids are common in dogs and ticks in Greece. Finally, the identification of 7 haplotypes for C. bainae confirms their genetic variability.

Abstract
Controlled experimental field study allowing natural exposure to sandflies. Two groups of 20 dogs each in two close sub-unit kennels. 7/20 dogs infected by L. infantum in the untreated group. 0/20 dogs infected by L. infantum in the fipronil-permethrin monthly treated group. 100 % protection obtained during this one-year study.
Canine vector-borne disease transmission can be reduced with regular use of repellent insecticides. The objective of this year-long experimental study was to assess the efficacy of a topical formulation of fipronil/permethrin (Frontline Tri-Act®) in preventing transmission of Leishmania infantum by sandflies. This clinical field trial was conducted in Xanthi (Northern Greece), an area highly endemic for canine leishmaniosis, from April 2018 to March 2019. Forty purpose-bred Beagle dogs, testing negative for L. infantum prior to study initiation, were enrolled in the study, which consisted of three phases: Phase 1 (field exposure phase) took place from Day 0–196. The dogs were randomly allocated to two groups, group 1 (sham-treated topically with sterile water) and group 2 (treated topically with Frontline Tri-Act®). Dogs in both groups were housed in two subunits of an open-air kennel for a period of 7 months, spanning the Leishmania transmission season. All dogs were treated or sham-treated on Days 0, 28, 56, 84, 112, 140 and 168. Clinical examinations, PCR analysis of conjunctival swabs, and serological tests were performed on a monthly basis. Sandflies were collected every 2 weeks, during a 12 -h period overnight using light traps. Each collection was placed in a container and kept refrigerated until speciation and PCR analysis could be performed. In the second phase of the study, from Day 197 to 252, the dogs were moved into a protected environment (insect-proof protected environment phase). CDC light traps were activated every 2 weeks inside and outside the kennels to ensure the vector-free status of the facility. Monthly clinical examinations, including PCR analysis of conjunctival swabs, and serological tests continued. At the end of the phase 2, bone marrow samples were collected on all dogs. Phase 3 (the final post-winter check) took place from Day 253 to 350. Dogs were released and adopted by individual private owners on Day 253. Follow up analyses included blood collection for SNAP tests and conjunctival swaps for PCR analysis on Days 304 and 350. Additionally, bone marrow collections were also performed on Day 350. Presence of sandflies was observed only in the phase 1 exposure period, and 1714 sandflies were collected (1427 females and 287 males). Two species were identified, Phlebotomus perniciosus var. tobbi and Phlebotomus neglectus. Out of the 62 pooled samples of sandflies assessed by PCR, three were considered positive (4.8 %). By the end of the study, 35 % of the Group 1 dogs (7/20) became positive based on PCR (conjunctival swab and bone marrow) and 30 % (6/20) based on SNAP/IFAT and ELISA tests, while all the dogs in the Frontline Tri-Act® treated group 2 remained negative for all tests (G1 vs G2, p = 0.008). All tests identified the same positive animals, and PCR allowed the detection of one additional infected dog. This clinical field trial demonstrated that monthly administration of Frontline Tri-Act® to dogs exposed to Leishsmania infection in a high endemic area provided 100 % preventive efficacy against transmission of L. infantum.

Abstract
Angiostrongylus vasorum is a nematode of the superfamily Metastongyloidea and was first described in the south of France in the nineteenth century where its biology was extensively studied in the 1960ies, leading to the common use of the byname "the French heartworm". The life cycle of the parasite is indirect including slugs and snails as intermediate hosts, while the adults live in the right heart and pulmonary arteries. Since then, many studies have been conducted in different European countries. However, there is scant knowledge regarding the prevalence and distribution of this parasite in Greece. Therefore, the objective of the present study was to investigate the current seroprevalence of A. vasorum in dogs in Greece. Overall 1000 apparently healthy and randomly selected dogs, presented in veterinary clinics, were involved at national level (n = 66 locations). Individual serum samples were obtained and tested using two in-house ELISAs by combining the detection of specific antibodies against the parasite and of circulating antigens of A. vasorum. Overall, 3.0% (n = 30, CI 95% 2.1 to 4.3%) of the sampled dogs were seropositive to at least one of the two ELISAs: 0.4% (n = 4, CI 95% 0.2 to 1.0%) were positive by both ELISAs, while 1.0% (n = 10, CI 95% 0.5 to 1.8%) were seropositive only for specific antibodies and 1.6% (n = 16, CI 95% 1.0 to 2.6%) were antigen-positive only. This is the first multicentric seroepidemiological study about A. vasorum in dogs from Greece. We showed that this parasite circulates in the local canine population and further studies should be carried out to elucidate its significance in the country.

Abstract
OBJECTIVE Minimally invasive techniques are the gold standard in surgery. Since conventional laparoscopic approach has been widely adopted, surgeons in their effort to further improve their skills passed to the era of the robotic assistance. The widespread adoption of robotics has led to the inevitable usage of robotic technology both in simple, as well as in more complicated procedures. Cholecystectomy is the "simple" surgical procedure to which every surgeon from the beginning of his career and besides specialization or subspecialization is exposed to, but the ran complications have a dramatic impact both for patient and doctor. The elimination of bile duct injury is crucial and robotics in the new era of surgery has to be the gold standard to a safe cholecystectomy. MATERIALS AND METHODS A comprehensive search of PubMed Database was conducted for English-language studies using the MeSH terms [Robotic cholecystectomy, bile duct injury]. We reviewed references of all reports for additional cases from 2000 to nowadays. We used the related articles link and searched the citations of reports in the ISI Science Citation Index to identify additional reports. RESULTS A total of 16 studies, including 2.264 patients that underwent robotic cholecystectomy were analyzed. Postoperative data and complications were collected from these studies. Bile duct injuries were more likely to be discovered during the first postoperative days as a bile leakage (8/2.264). One major bile duct injury was noticed, and most injuries were definitively treated at the hospital where the injury occurred with postoperative endoscopic retrograde cholangiopancreatography (ERCP) and stenting. CONCLUSIONS Robotic cholecystectomy is a safe and adequate alternative to conventional laparoscopic or open approach in term of safety. Furthermore, surgeons must be already experienced and familiar with robotic techniques, so as to overcome the problem of the bile duct injury.

Abstract
OBJECTIVE Endometrial cancer is increasingly prevalent in western societies and affects mainly postmenopausal women; notably incidence rates have been rising by 1.9% per year on average since 2005. Although the early-stage endometrial cancer can be effectively managed with surgery, more advanced stages of the disease require multimodality treatment with varying results. In recent years, endometrial cancer has been extensively studied at the molecular level in an attempt to develop effective therapies. Recently, a family of compounds that alter epigenetic expression, namely histone deacetylase inhibitors, have shown promise as possible therapeutic agents in endometrial cancer. The present review aims to discuss the therapeutic potential of these agents. MATERIALS AND METHODS This literature review was performed using the MEDLINE database; the search terms histone, deacetylase, inhibitors, endometrial, targeted therapies for endometrial cancer were employed to identify relevant studies. We only reviewed English language publications and also considered studies that were not entirely focused on endometrial cancer. Ultimately, sixty-four articles published until January 2018 were incorporated into our review. RESULTS Studies in cell cultures have demonstrated that histone deacetylase inhibitors exert their antineoplastic activity by promoting expression of p21WAF1 and p27KIP1, cyclin-dependent kinase inhibitors, that have important roles in cell cycle regulation; importantly, the transcription of specific genes (e.g., E-cadherin, PTEN) that are commonly silenced in endometrial cancer is also enhanced. In addition to these abstracts effects, novel compounds with histone deacetylase inhibitor activity (e.g., scriptaid, trichostatin, entinostat) have also demonstrated significant antineoplastic activity both in vitro and in vivo, by liming tumor growth, inducing apoptosis, inhibiting angiogenesis and potentiating the effects of chemotherapy. CONCLUSIONS The applications of histone deacetylase inhibitors in endometrial cancer appear promising; nonetheless, additional trials are necessary to establish the therapeutic role, clinical utility, and safety of these promising compounds.

Abstract
BACKGROUND/AIM Orthotopic Liver Transplantation (OLT) is the treatment of choice for patients with end stage liver disease, acute liver failure, hepatocellular carcinoma and metabolic disorders. As a result of improvement in surgical and anesthesiological skills, advanced understanding of transplant immunology and better critical care management of complications, patients survive longer after liver transplantation. It has been gradually achieved one-year survival rates of 80-90%. During the early post-operative period, all patients undergoing OLT are admitted to the intensive care unit, as they need a management of both preexisting patient's conditions and post-operative complications, usually due to either adverse intra-operative or post-operative events. The purpose of this review is the detailed recording, understanding and interpretation of immediate post-operative complications occurred in patients undergoing OLT, in intensive care unit. This could help to improve patient's treatment and reduce the incidence of complications, with further reduction of morbidity-mortality and cost. We also present our experience from the first 32 OLT patients from Liver Transplantation Unit of Laiko General Hospital, the only Liver Transplantation Unit in Athens. MATERIALS AND METHODS This literature review was performed using the MEDLINE database. The key words were; Orthotopic liver transplantation; intensive care unit; post-operative complications; outcomes. One hundred-sixteen articles published in English until 2018 were used. We also use all the results from our 32 patients from our Liver Transplantation Unit during the period 07/2006 to 07/2009. RESULTS All patients undergoing OLT admitted to the intensive care unit for a period of time, depending on the occurrence of post-operative complications. The incidence of primary failure ranges between 2-14%, whereas post-operative bleeding ranges between 7-15%. The treatment is usually conservative, although surgical repair may need in 10-15%. Acute renal failure post-operative is not an infrequent problem too, and has been reported to occur in 9% to 78% of cases. Acute rejection normally occurs 7-14 days after OLT. Additionally, the delay of the weaning from mechanical ventilation in the immediate post-operative period could increase the complications. Infectious complications are quite common almost from the first post-operative day in intensive care unit. CONCLUSIONS Prolonged intensive care stay could increase the complications post-operative Infectious complications, renal and respiratory impairment are among the most common causes of early post-transplant morbidity and mortality.

Abstract
Background Canine vector-borne diseases (CVBDs) represent a wide group of diseases of major significance for canine health. In addition to their veterinary importance, many of these diseases are of great zoonotic concern, posing a risk of potential transmission to humans. To date, there has been scant knowledge regarding the prevalence, distribution and risk factors of CVBDs in Greece. Therefore, the objectives of the present study were to update the current knowledge on the seroprevalence of Dirofilaria immitis, Anaplasma spp., Ehrlichia spp. and Borrelia burgdorferi (sensu lato) in dogs in Greece and, furthermore, to assess possible environmental and any other risk factors associated with these infections. A total of 1000 apparently healthy and randomly selected dogs, presented in veterinary clinics, were involved at the national level (n = 66 municipalities). Serum samples were obtained from each individual dog and were tested using the SNAP® 4Dx® Plus kit from IDEXX Laboratories. Possible risk factors were assessed using binary regression models, including dogs’ lifestyle, climatological parameters and the altitude of the region. Results Overall, 21.8% (95% CI: 19.4–24.5%) of the sampled dogs were found to be seropositive to at least one of the four pathogens examined. The most prevalent pathogen was Ehrlichia spp. (12.5%, 95% CI: 10.6–14.7) followed by D. immitis (9.0%, 95% CI: 7.8–11.5) and Anaplasma spp. (6.2%, 95% CI: 4.9–7.9). The lowest prevalence (0.1%) was recorded for B. burgdorferi (s.l.) where only one dog was found to be positive. Among the examined risk factors, low mean temperature was found to increase the prevalence of Ehrlichia spp. (P ≤ 0.001) and Anaplasma spp. (P ≤ 0.001), while low minimum temperature increased the prevalence of D. immitis (P ≤ 0.001). In addition, low total annual rainfall had an effect of the prevalence of Ehrlichia spp. (P ≤ 0.01). Altitude also had a significant effect on the prevalence of D. immitis (P ≤ 0.05) and Anaplasma spp. (P ≤ 0.01). Conclusions To our knowledge, this is the first large-scale seroepidemiological study of CVBDs in Greece. It has been evidenced that environmental factors such as temperature, rainfall and altitude can influence the prevalence and distribution of CVBDs.

Abstract
BACKGROUND Feline gastrointestinal parasitism constitutes an issue of concern for veterinarians since parasites are widespread and affect animals' health and welfare. Furthermore, some of these pathogens have zoonotic potential. To provide detailed data on the current epizootiology of feline endoparasitism, a multicentric survey was conducted during 2016. METHODS Faeces from 1150 cats were collected from all regions of Greece and examined by sedimentation and flotation techniques. Possible risk factors including gender, age, ownership status, living conditions and co-infections with other parasites were assessed using binary regression models for each one of the most prevalent parasites. RESULTS The overall gastrointestinal parasite prevalence in cats was 50.7%. The study population consisted of cats of both sexes, different age groups, ownership status and living conditions. A total of 10 gastrointestinal parasitic species were detected and up to 5 different parasites were isolated in the same faecal sample. The most frequently identified parasites were Toxocara cati (n = 278; 24.2%), followed by Cystoisospora spp. (n = 189; 16.4%), Ancylostomatidae (n = 186; 16.2%), Aelurostrongylus abstrusus (n = 40; 3.5%), Giardia spp. (n = 26; 2.3%), Joyeuxiella pasqualei (n = 14; 1.2%), Capillaria aerophila (n = 8; 0.7%), Dipylidium caninum (n = 3; 0.2%), Toxascaris leonina (n = 2; 0.1%) and Troglostrongylus brevior (n = 2; 0.1%). The occurrence of co-infections was 11.6%. Concerning risk factors, the likelihood of T. cati infection was higher for female cats living outdoors and for cats being infected with Cystoisospora spp. In the same frame, young, stray, male and free of A. abstrusus cats were more likely to be infected with Cystoisospora spp. Correspondingly, stray, infected with Giardia spp. but free of Cystoisospora spp. cats were more likely to be infected with Ancylostomatidae. Regarding A. abstrusus infection, a higher probability was reported for cats living outdoors and for cats free of Cystoisospora spp., while Giardia spp. infections were more common in young and co-infected with Ancylostomatidae animals. CONCLUSIONS The prevalence of parasitized cats in Greece was high and thus consideration should be paid to control the risk factors, to implement targeted preventive antiparasitic treatments and educate cat owners on the value of prevention for the health and welfare of their cats.

Abstract
Canine vector-borne diseases are highly endemic in European countries of the Mediterranean basin. The use of repellent insecticides aids to reduce the risk of pathogen transmission. The primary objective of this 5-month serological field study conducted in a highly endemic area of canine leishmaniosis in Greece was to comparatively assess the effectiveness of a topical formulation of fipronil/permethrin (Frontline Tri-Act®/Frontect®) and of a deltamethrin collar (Scalibor®) for the prevention of Leishmania infantum transmission. Initially, 72 clinically healthy owned dogs were sampled for inclusion. Ten out of the 72 (13.8%) were seropositive according to the Snap Leish® ELISA test and removed. Ultimately, a total of 56 dogs were followed from May to October 2015 with monthly blood samples and serological tests based on Snap Leish® and Snap 4Dx® ELISA tests. Twenty-five dogs were treated with deltamethrin collar (Scalibor®) (Group 1) and 31 were treated monthly with the topical fipronil/permethrin formulation (Group 2). In group 1, three dogs out of 25 (12%) seroconverted for Leishmania whereas none of the dogs (0/31) seroconverted in group 2. In addition, this trial provided means to serological assess the transmission of other vector-borne pathogens. Regarding Anaplasma spp., one dog in each group was seropositive at the beginning of the study and no dogs became positive during the study. For Ehrlichia canis, 9/25 (36%) dogs in group 1 and 5/31 (16.1%) in group 2 were seropositive at inclusion time. Two out of 16 (11.8%) and 3/26 (11.5%) dogs became positive for E. canis after 3months in groups 1 and 2, respectively. No Borrelia burgdorferi sensu lato seropositive dog was found during the study. In regard to Dirofilaria immitis, 7/25 (28%) dogs and 12/31 (38.7%) were antigen-positive in groups 1 and 2, respectively, at inclusion. There was no significant difference between groups 1 and 2 in regard to new seroconversions during the trial. This study, conducted in a highly endemic area for vector-borne pathogen transmission, confirmed that the use of deltamethrin and permethrin is a suitable approach to reduce the risk of L. infantum infection by sandflies.
