Adverse Reactions to Field Vaccination Against Lumpy Skin Disease in Jordan.

Lumpy skin disease (LSD) is an emerging disease in the Middle East region and has been recently reported in Jordan. The aim of this study was to investigate the adverse reactions that were reported after vaccine administration. Geographical areas enrolled in the study were free of the disease and away from the outbreak governorate. Sixty-three dairy cattle farms, with a total of 19,539 animals, were included in the study. Of those, 56 farms reported adverse clinical signs after vaccine administration. The duration between vaccine administration and appearance of adverse clinical signs ranged from 1 to 20 days (Mean = 10.3, SD ± 3.9). Clinical signs were similar to those observed with natural cases of lumpy skin disease. These were mainly fever, decreased feed intake, decreased milk production and variable sized cutaneous nodules (a few millimetres to around 2 cm in diameter) that could be seen anywhere on the body (head, neck, trunk, perineum), udder, and/or teats. Nodules were raised and firm initially and then formed dry scabs that could be peeled off the skin. The characteristic deep 'sit fast' appearance was rarely seen and most lesions were superficial. Some cattle had swollen lymph nodes, while a few pregnant animals aborted. The percentage of affected cattle ranged from 0.3 to 25% (Mean = 8, SD ± 5.1). Fever, decreased feed intake, and decreased milk production were seen in 83.9, 85.7, and 94.6% in cattle on the affected farms, respectively. All affected cattle displayed skin nodules over their entire bodies, while 33.9 and 7.1% of the affected farms reported nodular lesions present on the udders and teats, respectively. No mortalities were reported due to vaccine adverse reactions. Duration (course) of clinical signs ranged from 3 to 20 days (Mean = 13.7, SD ± 4.1). Two types of LSD vaccines were used by the farmers in this study. The first one was a sheep pox virus (SPPV) vaccine derived from the RM65 isolate [Jovivac, manufactured by Jordan Bioindustries Centre (JOVAC)] and the other an unlabelled one, which was later identified using PCR as a strain of lumpy skin disease virus (LSDV). Blood and skin samples collected from cattle vaccinated with the LSDV vaccine were positive for LSDV using both general and species-specific PCR primers, whereas those from cattle vaccinated with the Jovivac vaccine were negative. Adverse reactions observed in cattle after administration of the LSDV vaccine were reported to be more severe than those seen after Jovivac vaccine administration and were comparable with clinical signs observed in natural infections.

Liver Transplantation for Budd-Chiari Syndrome With Large Solitary Focal Nodular Hyperplasia of the Liver in a Patient With Essential Thrombocythemia: Case Report. [Corrected].

Budd-Chiari syndrome is a rare condition caused by interrupted hepatic venous outflow in the hepatic veins, inferior vena cava, or right atrium. Reports from the literature have delineated on focal nodular hyperplasia (FNH)-like lesions in association with Budd-Chiari Syndrome. To our knowledge, there are no reports about true FNH lesions in patients with Budd-Chiari Syndrome. Focal nodular hyperplasia develops in disorders with aberrant circulation and vasculature. We report a case of Budd-Chiari syndrome in association with large solitary FNH in a 22-year-old man who was referred to our institution with sudden intermittent right upper quadrant abdominal pain, vomiting, diarrhea with pale stool, decreased appetite, dark urine, and abdominal distention for 15 days. Laboratory investigations revealed anemia, thrombocytosis, and abnormal liver function tests and coagulation profile. Imaging revealed hepatic vein thrombosis, confirming Budd-Chiari syndrome, and a 6.2 × 6.1 × 6.8 cm lesion in segment 8 of the liver. Primary cause of Budd-Chiari syndrome was essential thrombocythemia according to bone marrow biopsy and molecular testing results. The patient was treated medically and underwent transjugular intrahepatic portosystemic shunt insertion. The lesion in segment 8 continued to enlarge. Cadaveric liver transplantation was carried out. On gross and histologic examination of the explanted liver, the lesion was found to be a true FNH.

New sampling strategy using a Bayesian approach to assess iohexol clearance in kidney transplant recipients.

BACKGROUND: Glomerular filtration rate (GFR) measurement is a major issue in kidney transplant recipients for clinicians. GFR can be determined by estimating the plasma clearance of iohexol, a nonradiolabeled compound. For practical and convenient application for patients and caregivers, it is important that a minimal number of samples are drawn. The aim of this study was to develop and validate a Bayesian model with fewer samples for reliable prediction of GFR in kidney transplant recipients. METHODS: Iohexol plasma concentration-time curves from 95 patients were divided into an index (n = 63) and a validation set (n = 32). Samples (n = 4-6 per patient) were obtained during the elimination phase, that is, between 120 and 270 minutes. Individual reference values of iohexol clearance (CL(iohexol)) were calculated from k (elimination slope) and V (volume of distribution from intercept). Individual CL(iohexol) values were then introduced into the Bröchner-Mortensen equation to obtain the GFR (reference value). A population pharmacokinetic model was developed from the index set and validated using standard methods. For the validation set, we tested various combinations of 1, 2, or 3 sampling time to estimate CL(iohexol). According to the different combinations tested, a maximum a posteriori Bayesian estimation of CL(iohexol) was obtained from population parameters. Individual estimates of GFR were compared with individual reference values through analysis of bias and precision. A capability analysis allowed us to determine the best sampling strategy for Bayesian estimation. RESULTS: A 1-compartment model best described our data. Covariate analysis showed that uremia, serum creatinine, and age were significantly associated with k(e), and weight with V. The strategy, including samples drawn at 120 and 270 minutes, allowed accurate prediction of GFR (mean bias: -3.71%, mean imprecision: 7.77%). With this strategy, about 20% of individual predictions were outside the bounds of acceptance set at ± 10%, and about 6% if the bounds of acceptance were set at ± 15%. CONCLUSIONS: This Bayesian approach can help to reduce the number of samples required to calculate GFR using Bröchner-Mortensen formula with good accuracy.

Effect of n-3 and n-6 polyunsaturated fatty acids on lymphocyte proliferation, interleukin production and phospholipid fatty acids composition in type 2 diabetic and healthy subjects in Jordan people.

Dietary lipid manipulation may affect a great number of immune parameters, such as lymphocyte proliferation, cytokine synthesis. In this study, lymphocytes of diabetic type 2 were incubated with different polyunsaturated fatty acid (docosahexaenoic, eicosapentaenoic, arachidonic acid) for investigated their effect on lymphoproliferation response, the concentration of interleukin 2 produced in each essay and phospholipid fatty acid composition of lymphocyte membrane. Our results found that the concanavalin A and insulin increase significantly the proliferative response while eicosapentaenoic, arachidonic and docosahexaenoic acid inhibited that by different degrees: 47%, 37% and 19%, respectively, for healthy subjects and 39%, 29% and 13% for diabetes. However, the concentration of IL-2 produced in presence of either docosahexaenoic, eicosapentaenoic or arachidonic acid was significantly reduced by 36%, 32% and 39%, respectively, in controls while 16%, 15% and 23%, respectively, in diabetics. On the other hand, the tested fatty acids demonstrated a major impact on the fatty acid composition of different phospholipid fractions of lymphocyte membrane but these fractions were different in their response to each fatty acid examined. For instance, the addition of docosahexaenoic acid to culture media was accompanied with a predominant composition of docosahexaenoic acid in phospholipid fractions. Also, our results showed a notable increased proportion of arachidonic, eicosapentaenoic and docosahexaenoic acids in control phospholipid fractions than those of diabetic.

Delinquency and social changes in United Arab Emirates: a comparison study between delinquent males and females on the family functioning questionnaire.

The purpose of this study was to specify descriptive elements of juvenile delinquents in United Arab Emirates (UAE); a comparison between male and female young offenders was also conducted using the Family Functioning Questionnaire (FFQ). The results revealed that some of the characteristics of young offenders were: school dropouts, had parents with no or some elementary education, lived in the city, and came from low income families. The statistical analysis revealed that there were significant differences between males and females on the FFQ subscales. That is, there was a differential treatment of male and female delinquents in the UAE society. Suggestions, implications and limitations for the potential use of the results reported in this study are also discussed.

Adolescents' perceptions of family functioning in the United Arab Emirates.

A sample of 710 subjects between 14 and 19 years of age were examined to assess psychological health of United Arab Emirates (UAE) families with adolescent members. The Family Functioning Questionnaire (FFQ) based upon the adolescent's perception of his or her family life and climate contains seven dimensions that constitute the family functioning process: family structure, emotional fulfillment, internal relations, behavioral control, value transmission, basic requirements, and external relations. Results indicate that the adolescents perceived their families to be operating more toward the functional than dysfunctional end of the scale. Males scored their families more functional in family structure and in external relations more significantly than did females. Females perceived their families as more functioning in internal relations, behavioral control, and basic requirements. However, a trend was found in favor of males on emotional fulfillment. Family functioning scores were higher in upper social economic status (SES) families than in other SES levels.
