Objective. The purpose of the present study was to test the hypothesis that cardiac alterations participate within different stages of CVL. Materials and methods. Twenty-eight dogs were diagnosed with CVL, were classified [based on clinical signs, rapid ELISA/IFAT, hematological and serum biochemical tests, urinary protein/creatinine ratio, ECG and ECHO]. as follows; group I (mild disease), group II (moderate disease), group III (severe disease), group IV (very severe disease) and group V included healthy controls. Results. Ig G antibodies against leishmaniasis as tested by IFAT, were deemed 1/64 to 1/16000 among infected groups. There were statistical significance regarding mean values for WBC [among healthy control group (V.) and other groups (p=0.049)], RBC [among stage III-stage IV and other groups (p=0.001)], Hb [between stage I and stage III-stage IV (p=0.008), HCT [between stage I and other groups (p = 0.001)] MCHC [between stage I and stage II- stage IV (p=0.046)], serum creatinine [(p=0.008) stage IV and stage I-II within group V], serum protein [(p=0.002) among stage IV and stage I-III- healthy control groups] and serum albumine [(p=0.004) among stage IV and stage I-II]. There was no alteration in CTnI concentrations,among groups. UPC analysis revealed statistical difference among control group and stage II to IV dogs (p=0.000). Moderate or severe ECG abnormalities were detected in 6/28 of diseased dogs. Regarding ECHO examination LA/ Ao value presented significant difference (p=0.003) among stage IV and other groups. Conclusions. It may be suggested that establishing Leishvet Working Group to those of dogs classified into stage I to IV, ECG [left atrial/ventricular enlargement, myocardial hypoxia] and ECHO [left atrial dilation, decrased/increased LVIDs, decrased/increased LVIDd, shortened FS and EF (systolic dysfunction)] alterations must be taken into account along with hematological and serum biochemical analysis.

Nepal possesses a good solar resource, and there has been increasing interest in the use of photovoltaic systems. About 1.1 million solar home systems, rated at nearly 30 MWp, have been installed across Nepal. With the introduction of net metering by the Nepal Electricity Authority, an increase in rooftop photovoltaics (RPV) is expected. However, to inform any policy developments around increased electricity generation, and the uptake of RPV, there is a need to quantify the potential of such systems (a situation mirrored in many developing countries). To this end, this study utilized a hierarchical geospatial technique based on open-source data to estimate the potential output from RPV in several cities in Nepal (Kathmandu, Pokhara, Butwal, Nepalgunj, and Biratnagar). It was found that the potential theoretical output of RPV ranged from 637 GWh per annum, in Kathmandu, to 50 GWh per annum in Butwal. Moreover, the total RPV potential from urban households of Nepal was estimated to be in the order 6.5 TWh per annum. As such, the findings of this paper can be used to make informed policy decisions about the future of Nepal’s energy mix.

The article focuses on Neospora caninum in dairy and beef cattle in Turkey. Neospora caninum is a protozoan parasite of animals that was first recognized in dogs in 1984. The overall Neospora seroprevalence determined from 3,287 sera of cows in different provinces was 13.96%. In the Kars region, 2% of cows were positive for antibodies to Neospora. Findings suggest that a proportion of cattle in different parts of the country were infected with Neospora, which may be linked with pregnancy. Exposure to Neospora is indicated in serum analysis from an aborting cow.

The article discusses a study which investigated the prevalence of haemoplasmosis in sick anaemic and non anaemic cats in Ankara, Turkey. Cytological examination and polymerase chain reaction (PCR) assay were used in the study. Results showed that haemoplasma in the feline population was 18.9%. The diseased cats were more affected than the healthy cats and 100% of animals with signs of haemoplasmosis were PCR positive. In addition, no geographical influence on haemoplasmosis frequency was observed in non anaemic positive cats. Only Candidatus Mycoplasma haemominutum was seen by the PCR assay in the regions studied.

Canine parvoviral enteritis remains one of the commonest causes of death in young dogs. This study aimed to determine serum total antioxidant capacity (TAC) and total oxidant status (TOS) levels in dogs with canine parvoviral enteritis (CPV) and reveal the risk factors of DIC formation. Thirty dogs were included in the study. The dogs were divided into two groups; the first group consisted of 20 dogs diagnosed with CPV (study group) and the other group consisted of 10 healthy dogs aged 0-12 months (control group). The mean TAC value was 0.354±0.018 mmol Trolox equiv./L in the control group and 0.295±0.007 mmol Trolox equiv./L in the study group. The mean TOS level was determined as 6.539±0.154 µmol H2O2/L in the control group and 7.934±0.364 µmol H2O2/L in the study group. The mean nitric oxide (NO) concentration was 18.613±0.856 µmol/L in the control group and 21.781±0.913 µmol/L in the study group. D-dimer levels were found to be 0.170±0.070 mg/dL in the control group and 2.585±0.584 mg/dL in the study group. As a result, it was demonstrated that it is essential to consider that oxidative stress increases and antioxidant capacity decreases in dogs with CPV and that disseminated intravascular coagulation (DIC) may develop in dogs with CPV. It is thought that considering oxidative stress and DIC during the treatment may contribute positively to prognosis and survival. [ABSTRACT FROM AUTHOR]

INTRODUCTION: In the first assessment of trauma patients with major vascular injuries, we need effective and rapid-acting homeostatic materials. In this study we compare the efficiencies of Ankaferd Blood Stopper® and a chitosan linear polymer (Celox®) in an experimental rat model with femoral artery bleeding. METHODS: Thirty male Wistar albino rats weighing 200- 250 g were divided into 3 groups: control, Ankaferd, and chitosan. The femoral artery and vein were visualized and bleeding was started by an incision. The bleeding time was recorded and categorized as ‘bleeding stopped at the second minute', ‘bleeding stopped at the fourth minute', and ‘unsuccessful' if bleeding continued after the fourth minute. RESULTS: In the control group, 60% of the bleeding did not stop. In the first 4 min in the Ankaferd group, the bleeding stopped in all rats; only in 1 of the rats in the chitosan group did the bleeding not stop. In stopping the bleeding in the first 4 min, Ankaferd was similar to chitosan but better than the control group; the chitosan group was similar to the control, but the p-value was close to significance. DISCUSSION AND CONCLUSION: For major arterial bleeding, the main treatment is surgical bleeding control, but outside of the hospital we can use buffers containing Ankaferd and chitosan on the bleeding region. The results of this study should be supported with larger studies. Furthermore, in our study, healthy rats were used. New studies are needed to evaluate the results of hypovolemic and hypotensive cases with major artery bleeding.

Objetivo. El propósito del presente estudio fue probar la hipótesis de que las alteraciones cardíacas participan en diferentes estadios de CVL. Materiales y métodos. Perros fueron diagnosticados con CVL, se clasificaron de la siguiente manera; Grupo I (enfermedad leve), grupo II (enfermedad moderada), grupo III (enfermedad grave), grupo IV (enfermedad muy grave) y grupo V controles sanos incluidos. Resultados. Los anticuerpos Ig G contra la leishmaniasis en el grupo como probado por IFAT, se consideraron 1/64 a 1/16000 entre los grupos infectados. Considerando los niveles de cTnI, hubo diferencias significativas (p=0,018). Entre el grupo IV y el grupo control sano, además entre el grupo IV y el grupo I. Considerando los niveles D-dímero, hubo diferencia entre el grupo control sano y el grupo II, III y IV (p=0,005). Teniendo en cuenta los niveles de NT-proBNP, hubo diferencia estadística entre el grupo de control sano y el estadio III, IV, además entre la etapa I con estadio III, IV (p=0,000). Conclusiones. Los resultados mostraron que los niveles de cTnI, Nt pro-BNP y D-dímero fueron mayores en perros infectados con CVL en contraste con perros sanos, en los que los niveles de estos biomarcadores estaban por debajo de los límites de detección. Los resultados obtenidos sugirieron la posibilidad de que cTnI y NT pro-BNP como marcadores de daño cardíaco y D-dímero como una herramienta de apoyo para un diagnóstico de tromboembolismo probable en perros con CVL.

Stroke occurs due to the interruption of blood flow to the brain and it is divided into ischemic and hemorrhagic. In the ischemic strokes, while the most commonly affected vessel is median cerebral artery (MCA), it is particularly affected bilateral posterior cerebral artery (PCA) is very rare condition. In this study, a case of sudden loss of vision and bilateral occipital infarct associated with bilateral vertebral system pathology and methylene tetrahydrofolate reductase (MTHFR) gene mutation were reported. A 62-year-old man was admitted with sudden loss of vision complaint starting 10 h before applying to emergency department. The patient was oriented and cooperative. On neurological examination, there was complete loss of vision in the right eye and only a response to light in the left eye. On the brain computerized tomography (CT), ischemic lesions were observed in the bilateral occipital areas and on magnetic resonance imaging (MRI), there were foci showing diffusion limitation in cortico-subcortical areas of bilateral parieto-occipital region. On the detailed examination at the clinic, MTHFR (a1298c) gene mutation was detected. Bilateral occipital infarction is rare and its diagnosis can be difficult because of its atypical symptoms. Therefore, occipital infarction should be suspected when the only sign is isolated vision loss in patients with risk factor for thromboembolism in their history and detailed visual-neurological examination of these patients should be performed. Keywords: MTHFR, Occipital infarctus, Visual loss

Background: The primary aim of this study was to identify and stratify candidate metrics used by anesthesiology residency program directors (PDs) to develop their residency rank lists through the National Resident Matching Program., Methods: Sixteen PDs comprised the participants, selected for diversity in geography and program size. We used a 3-round iterative survey to identify and stratify candidate metrics. In the first round, participants listed metrics they planned to use to evaluate candidates. In the second round, metrics from the first round were ranked by importance, and criteria were solicited to define an exceptional, strong, average, marginal, and uncompetitive candidate for each metric. In the third round, aggregated results were presented and participants refined their rankings., Results: Of the 16 PDs selected, 15 participated in the first and second survey rounds, and 10 in the third. Eighteen candidate metrics were indicated by 8 or more PDs for residency selection. All 10 PDs from the final round identified passing Step 1 of the United States Medical Licensing Exam (USMLE) and the absence of "red flags" like a failed rotation as key selection metrics, both averaging an importance score of 4.9 out of 5. Other metrics identified by all PDs included clerkship evaluation comments, USMLE Step 2 scores, class rank, letters of recommendation, personal statement, and program and geographical signals., Conclusions: The study reveals key metrics anesthesiology residency PDs use for candidate ranking, which may offer candidates insights into their competitiveness for anesthesiology residency., (© 2024 Society for Education in Anesthesia.)

Manipulation of skin biogeography has been the subject of study by the present authors for a very long while. Previous description and report identified the benefical application of skin microbiota transplantation (SMT) by the same researcher group, whom described unenriched skin microbiota transplantation at clinical veterinary practice for the first time among dogs. This study to our knowledge again for the first time reported herein aimed to investigate Un-smt application for treatment of feline atopic skin syndrome (FASS). This novel treatment intervention was performed similarly to previous description and methodology by use of Nivea Refining Clear-Up Strips (Ni-RcUs) either in autologue or heterologue route. Clinical biomarker for detecting the efficacy of Un-smt via Ni-RcUs evolved epidermal corneometric analytes (i.e. epidermal hydration and pH), relevant clinical scores The Feline Dermatitis Extent and Severity Index (FeDESI) and Visual Analogue Scale (VAS pruritus) and clinical observations performed weekly, at least. Both FeDESI and VAS pruritus scores were changed in relationship with smt. Pre-treament day 0 FeDESI scores (median ± SE) (72.5 ± 9.34), were significantly (p=0.001) higher than scores on day 10 (13.5 ± 2.55) switching the severity of the disease in all cases. Besides day 0 VAS pruritus scores were 6.0 ± 0.49 (median ± SE) (prior to treatment), whereas owner VAS pruritus score was decreased to 2.0 ± 0.34 (median ± SE) significantly (p=0.001). There were no side effects attributable to treatment applications. All cases were monitored for 6 months after completion of treatment in which no recurrence was observed. As a preliminary conclusion with selected number of cats with FASS, Un-smt with Ni-RcUs should be novel strategy for manuplating skin microbiome with treatment success., Competing Interests: Conflict of interests: We have further interest for development of this technique.

Visceral Leishmaniasis (VL) and Monocytic Ehrlichiosis (ME), which are an important zoonotic diseases of dogs, causing multiple organ dysfunction and has a poor prognosis when not interfered. In this study, it was aimed to investigate the cardiovascular injury that develops in dogs that co‑infected with VL and ME with cardiovascular biomarkers and echocardiographic parameters. The animal material of this study was consisted of 14 owned dogs in total; 7 diseased dogs which were determined to be co‑infected with VL and ME according to the results of clinical examination and rapid test kits, and 7 healthy dogs, which were determined to be healthy as a result of the same examinations. As a result of echocardiographic examinations, decreased left ventricular cytolic and diastolic diameters (LVIDs, LVIDd), fractional shortening (FS) and increased ratio of left atrium to left aortic root diameter (LA/Ao) values were determined in the Co‑infected Group compared with the Healthy Group. Also, as a result of biomarker analysis, higher cTnI) D‑dimer and NT‑proBNP levels were detected in the Co‑infected Group. In conclusion, considering studies of dogs infected with VL and/or ME alone, it was concluded that similar cardiovascular injury develops in dogs co‑infected with VL and ME.

The study aimed to investigate the levels of arginine, symmetric dimethylarginine (SDMA), and asymmetric dimethylarginine (ADMA) in dogs with canine leishmaniasis (CanL) and their relationship with some renal and cardiovascular parameters. A total of 60 dogs were enrolled, including 40 with CanL and 20 healthy controls. The CanL group was divided into four stages based on clinical and laboratory findings. The levels of plasma arginine, SDMA, and ADMA were determined by high performance liquid chromatography (HPLC). The data from the healthy group were compared with those from the CanL group, and according to the stages. In dogs with CanL, systolic and diastolic blood pressure, plasma creatinine, cystatin-C, phosphorus, potassium, and low-density lipoprotein concentrations, the urine protein/creatinine ratio, the amount of nitric oxide, and creatine kinase-MB activity were higher, while the high-density lipoprotein concentration was lower compared to healthy controls. The concentration of arginine was low (p < 0.05) and the levels of ADMA (p < 0.001) and SDMA (p < 0.05) were high in dogs with CanL. There were no statistically significant differences in arginine concentration among the different stages of CanL. However, the concentration of plasma ADMA was higher in all stages of CanL compared to the healthy group, and the concentration of plasma SDMA was higher in Stage IV compared to the healthy group and Stage III. The present study demonstrates for the first time a decrease in arginine concentration and an increase in ADMA concentration in dogs with CanL. The increase in SDMA concentration in dogs with CanL was consistent with previous studies. However, compared to other renal parameters, SDMA exhibited limited performance distinguishing between clinical stages of CanL. These findings could be a source for future diagnostic and therapeutic studies to explain the renal and cardiovascular pathophysiology of CanL. Additional clinical studies that include treatment and patient follow-up with an assessment of the acute phase response are needed to provide a more detailed understanding of the changes observed in dogs with CanL., Competing Interests: Declaration of competing interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: Mehmet Gultekin reports financial support was provided by Scientific and Technological Research Council of Turkey (TUBITAK) - 117O894., (Copyright © 2023 Elsevier Ltd.

Purpose: Canine ehrlichiosis is an important tick-borne disease of dogs worldwide. In the present study, we aimed to determine the serum total antioxidant capacity (TAC), malondialdehyde (MDA), nitric oxide (NO), superoxide dismutase, (SOD), glutathione peroxidase (GSH-Px), adenosine deaminase (ADA) activity and serum protein profiles in dogs affected with naturally acquired ehrlichiosis., Methods: The animal materials had been consisted of ten dogs naturally infected with Ehrlichia canis, and ten controls negative for Ehrlichia canis. TAC, MDA, NO, SOD, GSH-Px, ADA activity and TP, ALB, GLOB levels were measured in sera of the animals. The serum protein concentrations were measured by autoanalyzer. The electrophoretic profiles of serum total protein were determined by native polyacrylamide gel electrophoresis (Native-PAGE)., Results: In dogs with ehrlichiosis, decreased TAC (P < 0.05) and GSH-Px (P > 0.05) levels were determined. However, NO (P > 0.05), SOD (P < 0.05), ADA (P > 0.05), MDA (P > 0.05), TP (P < 0.05) and GLO (P < 0.05) levels were found as increased in the Ehrlichia positive dogs. ALB levels were decreased without a statistical significance (P > 0.05). ALB, α1 and β2 globulin strip densities were found as decreased in native-PAGE, while β1 and γ globulin strip densities were significantly increased in the E. canis positive group when compared to the control., Conclusion: It was determined that the oxidative stress decreased high antioxidant activity in dogs naturally infected with E. canis, and consequently, pro-oxidant and antioxidant defense and serum protein profiles were affected. It was thought that antioxidant supplementation could be beneficial to the treatment of the disease., (© 2021. Witold Stefański Institute of Parasitology, Polish Academy of Sciences.)

Antiphospholipid syndrome (APS) is an acquired autoimmune condition characterized by the presence of antiphospholipid antibodies (lupus anticoagulant, anticardiolipin antibody, and anti-β 2 glycoprotein-I antibody) which leads to clinical thrombosis via a multifactorial mechanism of action. Despite the propensity to form clot in vivo, these antibodies interfere with the assembly of the prothrombinase complex on phospholipids in in vitro assays, leading to prolongation of activated clotting time and activated partial thromboplastin time. This disconnect between what occurs in vivo and in vitro makes monitoring anticoagulation during cardiac surgery particularly complex. We present a patient with APS undergoing coronary artery bypass grafting with cardiopulmonary bypass. We delineate our strategy for managing anticoagulation in the presence of this syndrome using the Hepcon Hemostasis Management System Plus (Medtronic, Inc. Minneapolis, MN) device by targeting whole blood heparin concentration to monitor anticoagulation., (© Copyright 2020 AMSECT.)

Background: Plasma citrulline (CIT) concentration is considered to be a reliable marker of functional enterocyte mass, primarily in humans. However, information about CIT levels along with related metabolites, arginine (ARG), nitric oxide (NO), and ammonia in neonatal calves are lacking., Objectives: To compare plasma CIT, ARG, NO, and whole blood ammonia concentrations in neonatal calves with acute diarrhea with those in healthy calves and to assess their possible relationships with diarrhea-related criteria., Animals: Seventy neonatal calves (60 with acute diarrhea and 10 healthy)., Methods: Observational case-control study. Diarrheic calves were classified into subgroups on the basis of etiology, severity of diarrhea, degree of dehydration, and systemic inflammatory response syndrome (SIRS) status. Plasma CIT and ARG concentrations were measured by liquid chromatography/tandem mass spectrometry., Results: Plasma CIT (median [range]: 67.5 [61.9-75.4] vs 30.1 [15.0-56.1] μmol/L) and ARG (170.7 [148.5-219.5] vs 106.1 [54.4-190.7] μmol/L) were lower and plasma NO (4.42 [3.29-5.58] vs 6.78 [5.29-8.92] μM) and blood ammonia concentrations (28.7 [26.1-36.9] vs 59.8 [34.6-99.5] μmol/L) were higher in the neonatal calves with diarrhea (P < .001). Plasma CIT (β = -0.29, P = .02), ARG (β = -0.33, P = .01), NO (β = 0.55, P < .001), and blood ammonia (β = 0.63, P <.001) were affected by SIRS status. Except for ammonia (0.52), the effects sizes for severity of diarrhea and degree of dehydration were small (ηp2 ≤ 0.45) for CIT, ARG, and NO., Conclusions and Clinical Importance: The changes in these variables might have diagnostic, prognostic, and therapeutic value in diarrheic neonatal calves., (© 2019 The Authors.

Background: Results of a previous study revealed an over-ordering of blood products for cardiac surgery and led to the creation of a new blood ordering algorithm. This follow-up study has been conducted to evaluate improvement in ordering practices., Methods: Retrospective data were collected for 171 patients who underwent coronary artery bypass grafting or valve surgery from March 2015 to March 2016 to determine the crossmatch-to-transfusion ratio (C:tx) and potential cost savings. Results were compared with pre-algorithm values and considered statistically significant if the 95% confidence interval did not include zero., Results: Prior to the algorithm, 100% of patients undergoing cardiac surgery were crossmatched. After instituting the algorithm, this decreased to 15%. The overall C:tx decreased from 7.97 to 2.14. Cost savings were calculated as $114.79 (coronary artery bypass grafting) and $129.05 (valve surgery) per patient., Conclusions: The creation of a new algorithm to guide ordering practices has significantly improved the C:tx, reduced unnecessary crossmatching, and lowered costs.

Introduction: This retrospective study examined the role of aortic valve (AV) disease in patients who underwent orthotopic liver transplantation (OLT) to determine the incidence of postoperative cardiac morbidity and mortality when compared with a matched control group without AV disease., Methods: Patients were included in the AV group if diagnosed with aortic stenosis (AS) or aortic regurgitation or had received AV replacement prior to OLT. The AV group (n = 53) was matched to a control group (n = 212) with the following preoperative variables: type of organ transplanted, age, gender, race, body mass index, MELD, redo-transplantation, preoperative renal replacement therapy, nonalcoholic steatohepatitis, viral hepatitis, diabetes, and coronary artery disease. A 1:4 ratio was utilized to improve the efficiency and power of the analysis., Results: No significant difference in survival or posttransplant cardiac complications (acute coronary syndrome, heart failure, or dysrhythmia) was observed between groups. However, statistically significantly more patients-11% (6/53)-required coronary intervention following OLT in the AV group, whereas 3% (7/212) required coronary intervention (χ 2 = 5.8; P = .0156) in the control group. Following OLT, 9% (5/53) in the AV group required surgical or nonsurgical AV intervention, whereas no valvular events were observed in the control group. Event-free survival in the AV group, with an end point defined as AV intervention (n = 5) and death (n = 10), was 92% (49/53) at 1 year, 83% (44/53) at 3 years, and 72% (38/53) at 5 years., Conclusions: Patients with pretransplant AV replacement or AS have significant cardiac complications (myocardial infarction, AV replacement, or cardiac death) in 1 to 3 years post-OLT.

Objective: The purpose of the study was to investigate the oxidative status and lipid profile among dogs at different stages of visceral leishmaniasis (VL)., Methods: Dogs with VL were divided into four groups according to the classification reported by the Leishvet group: stage I (n=9), stage II (n=11), stage III (n=6), and stage IV (n=6); these dogs were compared to healthy control dogs (n=14). The lipid profile [high-density lipoprotein (HDL), low-density lipoprotein (LDL), cholesterol, and triglyceride levels) and oxidative status [total antioxidant capacity (TAC), total oxidant status (TOS), and paraoxonase-1 (PON-1) activity] were evaluated., Results: Compared to the control dogs, significant increases in the TOS and the LDL level and decreases in PON-1 activity and the HDL level were determined among the dogs at all stages of VL (p<0.05). No significant differences were found in the TAC and the cholesterol and triglyceride levels among the groups., Conclusion: Increased oxidative stress and alterations in lipid profile were observed among dogs with VL. However, no significant differences were detected between dogs at different stages of the disease. Therefore, changes in the TOS, PON-1 activity, and HDL and LDL levels in dogs at all stages of VL should be considered in the diagnosis of the disease and planning of the treatment.

This study aimed to evaluate the acute phase response (APR) through haptoglobin (Hp) and serum amyloid A (SAA) concentrations in serum and to examine the correlation between these acute phase proteins (APPs) and oocyst shedding using experimental Cryptosporidium parvum (C. parvum) infection model in neonatal lambs. Twenty lambs were divided into two equal groups: group CON remained uninfected as negative control and lambs of the group EXP were inoculated orally with 1×10 6 C. parvum oocysts. Blood and faecal samples were obtained from both groups before colostrum intake and prior to inoculation (day-1), and at 2, 6, 13, and 20days post-inoculation (dpi). The serum concentrations of SAA increased following the experimental infection of lambs with C. parvum, the difference being statistically significant from pre-inoculation levels at 2 dpi, while significant increases in serum concentration of Hp were observed at 2 and 6 dpi. At the same occasions, serum concentrations of both APPs were significantly higher in the C. parvum-infected lambs compared to the healthy control lambs. A moderate positive correlation (rho=0.67; p< 0.001) was observed between serum Hp concentration and oocyst count (OPG),whereas the serum SAA concentration didn't significantly correlate with OPG (rho=0.18; p>0.05). In conclusion, the results of the study shed some light on APR due to C. parvum infection in neonatal lambs., (Copyright © 2017 Elsevier B.V. All rights reserved.)
