    A sporadic outbreak of an unknown disease occurred among dairy cattle, from early February to late May 1955, in Japan. The characteristic symptoms of this disease were dyspnea and depilation; out of 29 cases, 8 died while 2 were slaughtered. Clinical studies have disclosed that the symptoms were similar to those found in cases of mercury poisoning as described by others. So the animals' feed was suspected of being the cause of the sickness. It was confirmed that the incident was due to poisoning resulting from ingestion of linseed meal treated with a mercurial fungicide. From the results of the testing anamnesis, it was found that 171 cattle were fed with the meal and 29 cases were affected. In veiw of the wide use of mercurial preparations for treating seed grains against fungi infection, a further experimental study was made on the effects of the feed and fungicide upon calves.

    investigate the genetic architecture of clinical mastitis and somatic cell score traits in dairy cattle using a high density (HD) SNP panel. Mastitis, an inflammation of the mammary gland most commonly caused by bacterial infection, is a frequent disease in dairy cattle. Clinical mastitis and somatic cell...... score from first three lactations were studied for association with SNP markers in 4,200 progeny-tested Nordic Holstein bulls. Single trait breeding values were used as phenotypes. All the individuals were genotyped with BovineSNP50 Beadchip. Part of this population was also genotyped with the Bovine...... mixed model analysis. After Bonferroni correction 12, 372 SNP exhibited genome-wide significant associations with mastitis related traits. A total 61 QTL regions on 22 chromosomes associated with mastitis related traits were identified. The SNP with highest effect explained 5.6% of the variance...

    Bovine leukocyte antigens (BoLA) are extensively used as markers for bovine disease and immunological traits. However, none of the BoLA genes in Southeast Asian breeds have been characterized by polymerase chain reaction (PCR)-sequence-based typing (SBT). Therefore, we sequenced exon 2 of the BoLA class II DRB3 gene from 1120 individual cows belonging to the Holstein, Sahiwal, Simbrah, Jersey, Brahman, and Philippine native breeds using PCR-SBT. Several cross-breeds were also examined. BoLA-DRB3 PCR-SBT identified 78 previously reported alleles and five novel alleles. The number of BoLA-DRB3 alleles identified in each breed from the Philippines was higher (71 in Philippine native cattle, 58 in Brahman, 46 in Holstein × Sahiwal, and 57 in Philippine native × Brahman) than that identified in breeds from other countries (e.g., 23 alleles in Japanese Black and 35 in Bolivian Yacumeño cattle). A phylogenetic tree based on the DA distance calculated from the BoLA-DRB3 allele frequency showed that Philippine native cattle from different Philippine islands are closely related, and all of them are closely similar to Philippine Brahman cattle but not to native Japanese and Latin American breeds. Furthermore, the BoLA-DRB3 allele frequency in Philippine native cattle from Luzon Island, located in the Northern Philippines was different from that in cattle from Iloilo, Bohol, and Leyte Islands, which are located in the Southern Philippines. Therefore, we conclude that Philippine native cattle can be divided into two populations, North and South areas. Moreover, a neutrality test revealed that Philippine native cattle from Leyte showed significantly greater genetic diversity, which may be maintained by balancing selection. This study shows that Asian breeds have high levels of BoLA-DRB3 polymorphism. This finding, especially the identification of five novel BoLA-DRB3 alleles, will be helpful for future SBT studies of BoLA-DRB3 alleles in East Asian cattle. PMID:25606401

    Full Text Available Macrophages and dendritic cells are recognized as key players in the defense against mycobacterial infection. Recent research has confirmed that alveolar epithelial cells (AECs also play important roles against mycobacterium infections. Thus, establishing a stable cattle AEC line for future endogenous immune research on bacterial invasion is necessary. In the present study, we first purified and immortalized type II AECs (AEC II cells by transfecting them with a plasmid containing the human telomerase reverse trancriptase gene. We then tested whether or not the immortalized cells retained the basic physiological properties of primary AECs by reverse-transcription polymerase chain reaction and Western blot. Finally, we tested the secretion capacity of immortalized AEC II cells upon stimulation by bacterial invasion. The cattle type II alveolar epithelial cell line (HTERT-AEC II that we established retained lung epithelial cell characteristics: the cells were positive for surfactants A and B, and they secreted tumor necrosis factor-α and interleukin-6 in response to bacterial invasion. Thus, the cell line we established is a potential tool for research on the relationship between AECs and Mycobacterium tuberculosis.

    The bovine MHC (BoLA) class II DRB3 alleles are associated with polyclonal expansion of lymphocytes caused by bovine leukemia virus (BLV) infection in cattle. To examine whether the DRB3*0902 allele, one of the resistance-associated alleles, is associated with the proviral load, we measured BLV proviral load of BLV-infected cattle and clarified their DRB3 alleles. Fifty-seven animals with DRB3*0902 were identified out of 835 BLV-infected cattle and had significantly lower proviral load (Pclass II DRA/DRB3*0902 molecule plays an important immunological role in suppressing viral replication, resulting in resistance to the disease progression.

    The sequential development of Type I and Type II ostertagiasis over a 2-year period in the same naturally infected cattle is described for the first time. Particular reference is made to biochemical and serological changes. Positive relationships were demonstrated between the clinical signs of both Type I and Type II disease, and marked increases in the levels of plasma pepsinogen, plasma gastrin and antibody titres to adult Ostertagia antigen. At necropsy, there were significant relationships between the combined total of adult and developing 5th stage larvae of Ostertagia spp. and the levels of both plasma pepsinogen and gastrin. By the end of the second grazing season the cattle had acquired an immunity to infection with Ostertagia spp. and had very low burdens of this parasite at necropsy. However some of these cattle maintained elevated plasma pepsinogen levels when under natural challenge by Ostertagia spp. larvae and the aetiology of these changes and the problems of diagnosis using this parameter are discussed. Similar trends of infection were observed for Cooperia oncophora, although resistance to the parasite developed more rapidly.

    Full Text Available The epidemiology, clinical picture and pathology of an outbreak of urolithiasis in cattle in southern Brazil are described. The disease occurred in August 1999 in a feedlot beef cattle herd. Five out of 1,100 castrated steers were affected. Clinical signs included colic and ventral abdominal distension. White, sand-grain-like mineral deposits precipitated on the preputial hairs. Affected cattle died spontaneously 24-48 hrs after the onset of the clinical signs. Only one animal recovered after perineal urethrostomy. Necropsy findings included calculi blocking the urethral lumen of the distal portion of the penile sigmoid flexure, urinary bladder rupture with leakage of urine into the abdominal cavity and secondary fibrinous peritonitis. Daily water intake was low since water sources were scarce and not readily available. The animals were fed rations high in grains and received limited amounts of roughage. Biochemical analysis revealed that the calculi were composed of ammonium phosphate. A calcium-phosphorus imbalance (0.4:0.6 was detected in the feedlot ration. For the outbreak, it is suggested that contributing factors to urolith formation include insufficient fiber ingestion, low water intake and high dietary levels of phosphorus. No additional cases were observed in that feedlot after preventive measures were established. Similar dietary mismanagement in fattening steers has been associated with obstructive urolithiasis in feedlot beef cattle in other countries.

    1999-01-01

    Clinical signs, causative factors, radiographic findings, type and duration of treatment or reason for killing were evaluated in 53 cattle (mean age: 5.3 years) suffering from toe ulcer and/or apical pedal bone necrosis. A total of 78 claws were affected. Four cattle suffered from a toe ulcer in one claw, 35 cattle showed osteolysis of the apex of the distal phalanx in a single claw and 14 cattle in two or three claws per cow. Overtrimming by means of a grinding disc and/or perforation of the sole was diagnosed as the major cause in 27 cattle (49%), laminitis in 30.2% and traumatic injuries in 11.3%. Radiography revealed a varying degree of osteolysis involving up to two-thirds of the pedal bone. Twenty-one cattle (39.6%) showing multiple toe disorders or involvement of one single claw with concurrent internal diseases were destroyed. In 23 cattle, the osteolytic bone was resected using a bone curette or hammer and chisel. Of these, the treatment was successful in 20 animals. The healing period ranged from 16-60 days when one claw was affected and from 43-53 days when two claws were affected. In five cattle, the digit was amputated

    Full Text Available This study was aimed to detect and record the clinical and ultrasonographic findings of the different complications resulted from the foreign bodies lodged in the compound stomach of cattle and buffaloes. A total of 105 animals (37 cattle and 68 buffaloes were subjected to study. Based on the clinical and ultrasonographic examination, animals were classified into; acute local reticuloperitonitis (ALRP (15 cattle and 28 buffaloes, chronic local reticuloperitonitis (CLRP (6 cattle and 14 buffaloes, acute diffuse reticuloperitonitis (ADRP (5 cattle and 3buffaloes, reticular abscesses (RA (4 cattle and 7 buffaloes, traumatic pericarditis (TP (6 cattle and16 buffaloes and liver abscess (one cattle. Results revealed that ALRP represented the highest percentage of 40.5% in cattle and 41.2 % in buffalos between the different complications of TRP. TP represented the second complications of higher incidence (16.2% in cows and 23.5% in buffalos. Liver abscess represented the lowest percentage (2.8% and was recorded in cows only. The pregnant animals were affected more than the non pregnant. Clinical findings represented in systemic reaction and pain tests were commonly encountered in TRP and its complications. Some of the affected animals were negatively respond to metal detector test. Results of the present study indicated that the ultrasonographic examination provide a specific echogenic pattern for the different complications of TRP. It was concluded that, clinical examination only is not efficient to give accurate diagnosis of foreign body lodged in the reticulum and rumen and their complications. Ultrasonography is a safe, non invasive diagnostic confirmatory method that could be used for early detection of such conditions.

       This study was carried out on 30 Holstein dairy cattle with acute clinical mastitis (ACM and 30 healthy ones. After confirmation of ACM through clinical examination, venous blood samples were collected and cardiac troponin I (cTnI was measured using chemiluminescence assay. Cardiac enzymes activities including CK-MB, AST and LDH were analyzed with special kits and spectrophotometric method. According to the findings mean heart rate (p=0.001, respiratory rate (p=0.026, and rectal temperature (p=0.030 were significantly increased in diseased group. cTnI level was 1.018 ± 0.235 ng/ml in cattle with ACM, which was significantly higher than healthy cattle (0.011±0.006 ng/ml; p=0.000. Other cardiac biomarkers were increased in diseased group, however elevation of serum activities of AST (p=0.047 and CK-MB (p=0.000 were statically significant. Although serum LDH activity in diseased group was higher than control group; but this difference was statistically non-significant (p=0.454. There were significant positive correlations between cTnI concentration with heart rate (p=0.018; r=0.853, respiratory rate (p=0.024; r=0.671, and rectal temperature (p=0.038; r=0.542. Heart rates were significantly correlated with serum activities of CK-MB (p=0.047; r=0.722 and AST (p=0.035; r=0.649. These results indicate some degree of heart damage caused by acute clinical mastitis in dairy cattle.

    Clinical mastitis as a frequently recurrent event can cause substantive economic loss on dairy farms. The reason for recurrent mastitis can be either a persistent infection of the bovine mammary gland by a mastitis pathogen or a reinfection of a quarter or udder after bacteriological cure. The virulence properties of a mastitis pathogen and the cure odds of an individual cow determine the development of persistent infections. Clinical episodes may alternate with periods without symptoms in the course of persistent infections. Strategies to reduce cases of recurrent mastitis have to include improved treatment concepts and measures to decrease new infection rates. The present literature review summarises the knowledge of definitions, frequencies, causes and effects of recurrent mastitis.

    Historically, dwarfism was the major genetic defect in U.S. beef cattle. Aggressive culling and sire testing were used to minimize its prevalence; however, neither of these practices can eliminate a recessive genetic defect. We assembled a 4-generation pedigree to identify the mutation underlying dwarfism in American Angus cattle. An adaptation of the Elston-Steward algorithm was used to overcome small pedigree size and missing genotypes. The dwarfism locus was fine-mapped to BTA6 between markers AFR227 and BM4311. Four candidate genes were sequenced, revealing a nonsense mutation in exon 15 of cGMP-dependant type II protein kinase (PRKG2). This C/T transition introduced a stop codon (R678X) that truncated 85 C-terminal amino acids, including a large portion of the kinase domain. Of the 75 mutations discovered in this region, only this mutation was 100% concordant with the recessive pattern of inheritance in affected and carrier individuals (log of odds score = 6.63). Previous research has shown that PRKG2 regulates SRY (sex-determining region Y) box 9 (SOX9)-mediated transcription of collagen 2 (COL2). We evaluated the ability of wild-type (WT) or R678X PRKG2 to regulate COL2 expression in cell culture. Real-time PCR results confirmed that COL2 is overexpressed in cells that overexpressed R678X PRKG2 as compared with WT PRKG2. Furthermore, COL2 and COL10 mRNA expression was increased in dwarf cattle compared with unaffected cattle. These experiments indicate that the R678X mutation is functional, resulting in a loss of PRKG2 regulation of COL2 and COL10 mRNA expression. Therefore, we present PRKG2 R678X as a causative mutation for dwarfism cattle.

    The current study compared the LeadCare(R) II test kit system with graphite-furnace atomic absorption spectrometry for blood lead (Pb) analysis in 56 cattle accidentally exposed to Pb in the field. Blood Pb concentrations were determined by LeadCare II within 4 hr of collection and after 72 hr of refrigeration. Blood Pb concentrations were determined by atomic absorption spectrometry, and samples that were coagulated (n = 12) were homogenized before analysis. There was strong rank correlation (R(2) = 0.96) between atomic absorption and LeadCare II (within 4 hr of collection), and a conversion formula was determined for values within the observed range (3-91 mcg/dl, although few had values >40 mcg/dl). Median and mean blood pb concentrations for atomic absorption were 7.7 and 15.9 mcg/dl, respectively; for LeadCare II, medians were 5.2 mcg/dl at 4 hr and 4.9 mcg/dl at 72 hr, and means were 12.4 and 11.7, respectively. LeadCare II results at 4 hr strongly correlated with 72 hr results (R(2) = 0.96), but results at 72 hr were lower (P atomic absorption. Although there have been several articles that compared LeadCare with other analytical techniques, all were for the original system, not LeadCare II. The present study indicated that LeadCare II results correlated well with atomic absorption over a wide range of blood Pb concentrations and that refrigerating samples for up to 72 hr before LeadCare II analysis was acceptable for clinical purposes.

    Lactoferrin (Lf) gene promoter was screened for the presence of single nucleotide polymphism in indigenous and crossbred cattle from North India and to evaluate its association with Mastitis. Study revealed the presence of genetic variation in regulatory region of bovine Lactoferrin gene using PCR-RFLP technique. Three genotypes namely GG, GH and HH were identified. A single nucleotide change, from guanine to adenine at 25th position was found to be significantly associated (pmastitis in indigenous Sahiwal and crossbred Karan Fries cattle maintained at organised herd of National Dairy Research Institute, Karnal. A non-significant association was observed between subclinical mastitis, somatic cell score (SCS), and GG genotype in Karan Fries cattle, however, a lower SCS was observed in animals having GG genotype. Overall a lower incidence of clinical mastitis was recorded in those animals having GG genotype of Lf in Sahiwal and Karan Fries (KF) cattle. The SNP identified in the promoter region may effect expression lactoferrin protein, which may lead to different levels of antibacterial and anti-inflammatory activity of Lf gene. Results from this study indicated the probable role played by Lactoferrin promoter to serve as candidate gene for mastitis susceptibility among indigenous and crossbred milch cattle.

    Full Text Available Studies covering all aspects of bovine viral diarrhoea virus (BVDV have been conducted in several countries in Europe, Asia and America. In southern Africa, more information is required about the nature of BVDV infection, the prevalence of different strains and the economic importance of the disease. The presence of BVDV in southern Africa has been known since the early 1970s through serological surveys but few reports confirming its presence by virus isolation and correlation with clinical disease are available. Specimens (n = 312 collected in 1998/99, from live and dead cattle from different farming systems, were obtained from private practitioners, feedlot consultants and abattoirs throughout the country. Specimens (n=37 from African buffaloes (Syncerus caffer in the Kruger National Park were also included. All specimens were processed for virus isolation in cell culture with confirmation by means of immunofluorescent antibody tests and some also by means of an antigen capture ELISA. BVDV was isolated from 15 (4.7 % cattle and were all noncytopathic biotypes. BVDV was not detected in 37 lymph nodes obtained from buffaloes in the Kruger National Park. Of the clinical signs in cattle from which virus were isolated, respiratory signs was the most frequent (10/15, followed by diarrhoea (5/15. Abortion, congenital malformations, haemorrhagic diarrhoea and poor growth were also included as criteria for selection of animals for specimen collection, but no BVD viruses were isolated from cattle manifesting these clinical signs.

    2017-05-01

    An economic selection index was developed for Beefmaster cattle in a general-purpose production system in which bulls are mated to a combination of heifers and mature cows, with resulting progeny retained as replacements or sold at weaning. National average prices from 2010 to 2014 were used to establish income and expenses for the system. Genetic parameters were obtained from the literature. Economic values were estimated by simulating 100,000 animals and approximating the partial derivatives of the profit function by perturbing traits 1 at a time, by 1 unit, while holding the other traits constant at their respective means. Relative economic values for the objective traits calving difficultly direct (CDd), calving difficulty maternal (CDm), weaning weight direct (WWd), weaning weight maternal (WWm), mature cow weight (MW), and heifer pregnancy (HP) were -2.11, -1.53, 18.49, 11.28, -33.46, and 1.19, respectively. Consequently, under the scenario assumed herein, the greatest improvements in profitability could be made by decreasing maintenance energy costs associated with MW followed by improvements in weaning weight. The accuracy of the index lies between 0.218 (phenotypic-based index selection) and 0.428 (breeding values known without error). Implementation of this index would facilitate genetic improvement and increase profitability of Beefmaster cattle operations with a general-purpose breeding objective when replacement females are retained and with weaned calves as the sale end point.

    Mastitis is the most common disease of dairy cattle, causing high economic losses each year. Studies to locate QTL affecting clinical mastitis and milk somatic cell counts have been carried out to increase our understanding of the disease. As part of the EU FP7 Quantomics project, we have used most...... recent genomic tools to characterize QTL affecting mastitis incidence in the Finnish Ayrshire cattle. Clinical mastitis diagnoses from -15 to 50 days and 51 to 300 days of first lactation and SCC (geometric mean of SCS observations between 5 to 170 days of first lactation) were included.

    To present the haematology and biochemistry profiles for cattle in New Zealand naturally infected with Theileria orientalis Ikeda type and investigate if the results differed between adult dairy cattle and calves aged cattle which tested positive for T. orientalis Ikeda type by PCR, that were submitted to veterinary laboratories in New Zealand between October 2012 and November 2014. Data sets for haematology and biochemistry results were prepared for adult dairy cattle (n=62 and 28, respectively) and calves aged cattle and calves cattle than for beef or dairy calves, for both haematology (pcattle and calves aged cattle infected with T. orientalis Ikeda type were consistent with extravascular haemolytic anaemia. Adult dairy cattle were more likely to be severely anaemic than calves. There were differences in haematology and biochemistry profiles between adult dairy cattle and calves, but most of these differences likely had a physiological rather than pathological basis. Overall, the haematological changes in calves aged cattle.

    Full Text Available A retrospective observational study was conducted to evaluate risk factors related to the cow and its environment on the occurrence of early events of clinical mastitis in dairy cattle of Costa Rica. Data on 313 406 lactations from 101 125 cows and 288 herds was available. The relative frequency of mastitis at the population level was 11.6%, ranging from 0.3% to 70.7% between herds. The population incidence rate was 4.65 cases per 10 000 days at risk in lactation, ranging from 0.092 to 5.7 between herds. Logistic regression was used to evaluate potential risk factors affecting incidence of clinical mastitis. Two generalized linear mixed models (GLMM were explored, without (base model and with (alternative model effects from previous lactation. The fixed factors with significant effect were: agroecological zone, racial group, year, number and month of calving, stage of lactation, duration and milk production in previous lactation, and history of mastitis in previous lactation. Categories with higher vs. lower propensity to mastitis were, respectively: tropical dry forest (OR Odds ratio: 11.03 vs. tropical rainforest (OR: 0.97, breed type Jersey×Brown Swiss (OR: 1.67 vs. Brown Swiss (OR: 1, birth-year before 1995 (OR:2.19 vs. after 2010 (OR: 1, fourth parity (OR:1.19 vs. first parity (OR: 0.54, month of calving March (OR: 1.25 vs. October (OR: 0.95, stage of lactation 1-30 days (OR:1.04 vs. 391-420 days (OR: 0.94. In covariates, an increase of 30 d in the previous lactation length was associated with an OR of 1.04 and an increase in production of 1000 kg in the previous lactation was associated with an OR of 1.17. These findings may be useful for the development of preventive protocols aimed at reducing the incidence of mastitis in groups with a higher risk.

    2007-05-01

    Previous clinical trials with our first prototype HIFU system (Teleson I) for the treatment of liver tumors, demonstrated a major challenge to be treatment of those tumors located behind the ribs. We have designed a new multi-element transducer for rib sparing. Initial simulation and experimental results (using a single channel power amplifier) are very encouraging. A new clinical HIFU system which can drive the multi-element transducer and control each channel independently is being designed and constructed. This second version of a clinical prototype HIFU system consists of a 3D motorised gantry, a multi-channel signal generator, a multi-channel power amplifier, a user interface PC, an embedded controller and auxiliary circuits for real-time interleaving/synchronization control and a to-be-implemented safety monitoring and data logging unit. For multi-element transducers, each element can be individually switched on and off for rib sparing, and phase and amplitude modulated for potential phased array applications. The multi-channel power amplifier can be switched on/off very rapidly at required intervals to interleave with ultrasound B-Scan imaging for HIFU monitoring or radiation force elastography imaging via a dedicated interleaving/timing module. The gantry movement can also be synchronised with power amplifier on/off and phase/amplitude updating for lesion generation under a wide variety of conditions including single lesions, lesion arrays and lesions "tracks" created whilst translating the active transducer. Results from testing the system using excised tissue will be presented.

    Mastitis is a mammary disease that frequently affects dairy cattle. Despite considerable research on the development of effective prevention and treatment strategies, mastitis continues to be a significant issue in bovine veterinary medicine. To identify major genes that affect mastitis in dairy cattle, 6 chromosomal regions on Bos taurus autosome (BTA) 6, 13, 16, 19, and 20 were selected from a genome scan for 9 mastitis phenotypes using imputed high-density single nucleotide polymorphism arrays. Association analyses using sequence-level variants for the 6 targeted regions were carried out to map causal variants using whole-genome sequence data from 3 breeds. The quantitative trait loci (QTL) discovery population comprised 4,992 progeny-tested Holstein bulls, and QTL were confirmed in 4,442 Nordic Red and 1,126 Jersey cattle. The targeted regions were imputed to the sequence level. The highest association signal for clinical mastitis was observed on BTA 6 at 88.97 Mb in Holstein cattle and was confirmed in Nordic Red cattle. The peak association region on BTA 6 contained 2 genes: vitamin D-binding protein precursor (GC) and neuropeptide FF receptor 2 (NPFFR2), which, based on known biological functions, are good candidates for affecting mastitis. However, strong linkage disequilibrium in this region prevented conclusive determination of the causal gene. A different QTL on BTA 6 located at 88.32 Mb in Holstein cattle affected mastitis. In addition, QTL on BTA 13 and 19 were confirmed to segregate in Nordic Red cattle and QTL on BTA 16 and 20 were confirmed in Jersey cattle. Although several candidate genes were identified in these targeted regions, it was not possible to identify a gene or polymorphism as the causal factor for any of these regions.

    The purpose of this investigation was to test the reliability of the American Optical Non-Contact Tonometer Mark II (NCT II) using the Goldmann Applanation Tonometer (GAT) as the validating instrument. The sample contained 102 consecutive patients from our University Eye Clinic, of whom one-half had 4 NCT II measurements first, followed by 4 GAT measurements; the other one-half had 4 GAT measurements first, followed by 4 NCT II measurements. No significant change in intraocular pressure (IOP) was noted over the measurement sequence with either instrument. There was no significant difference between paired NCT II and GAT readings when the NCT II was used first; however, a highly significant difference between paired readings was obtained when the GAT was used first, indicating that the GAT measurement produced a delayed reduction in the IOP. This effect did not occur with the NCT II. Although the NCT II is shown to have a good overall reliability when compared to the GAT in both protocols, the agreement between any two tonometers may be influenced greatly by the very process of taking a measurement and by the dynamic nature of the IOP.

    Mastitis is a major source of economic loss in dairy herds. The objective of this research was to evaluate the association between genotypes within SLC11A1 and CXCR1 candidate genes and clinical mastitis in Holstein dairy cattle using the selective genotyping method. The data set contained clinical mastitis records of 3,823 Holstein cows from two Holstein dairy herds located in two different regions in Iran. Data included the number of cases of clinical mastitis per lactation. Selective genotyping was based on extreme values for clinical mastitis residuals (CMR) from mixed model analyses. Two extreme groups consisting of 135 cows were formed (as cases and controls), and genotyped for the two candidate genes, namely, SLC11A1 and CXCR1, using polymerase chain reaction-single strand conformation polymorphism (PCR-SSCP) and polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP), respectively. Associations between single nucleotide polymorphism (SNP) genotypes with CMR and breeding values for milk and protein yield were carried out by applying logistic regression analyses, i.e. estimating the probability of the heterogeneous genotype in the dependency of values for CMR and breeding values (BVs). The sequencing results revealed a novel mutation in 1139 bp of exon 11 of the SLC11A1 gene and this SNP had a significant association with CMR (P G and these genotypes had significant relationships with CMR. Overall, the results showed that SLC11A1 and CXCR1 are valuable candidate genes for the improvement of mastitis resistance as well as production traits in dairy cattle populations.

    Bovine tuberculosis (bTB) poses serious risks to animal welfare and economy, as well as to public health as a zoonosis. Its etiological agent, Mycobacterium bovis, belongs to the Mycobacterium tuberculosis complex (MTBC), a group of genetically monomorphic organisms featured by a remarkably high overall nucleotide identity (99.9%). Indeed, this characteristic is of major concern for correct typing and determination of strain-specific traits based on sequence diversity. Due to its historical economic dependence on cattle production, Uruguay is deeply affected by the prevailing incidence of Mycobacterium bovis. With the world's highest number of cattle per human, and its intensive cattle production, Uruguay represents a particularly suited setting to evaluate genomic variability among isolates, and the diversity traits associated to this pathogen. We compared 186 genomes from MTBC strains isolated worldwide, and found a highly structured population in M. bovis. The analysis of 23 new M. bovis genomes, belonging to strains isolated in Uruguay evidenced three groups present in the country. Despite presenting an expected highly conserved genomic structure and sequence, these strains segregate into a clustered manner within the worldwide phylogeny. Analysis of the non-pe/ppe differential areas against a reference genome defined four main sources of variability, namely: regions of difference (RD), variable genes, duplications and novel genes. RDs and variant analysis segregated the strains into clusters that are concordant with their spoligotype identities. Due to its high homoplasy rate, spoligotyping failed to reflect the true genomic diversity among worldwide representative strains, however, it remains a good indicator for closely related populations. This study introduces a comprehensive population structure analysis of worldwide M. bovis isolates. The incorporation and analysis of 23 novel Uruguayan M. bovis genomes, sheds light onto the genomic diversity of this

    The clinical benefits of memantine, depending on the baseline cognitive and affective conditions in real world dementia clinics, have not been completely examined. We performed the "Okayama Memantine Study II (OMS II)" to retrospectively evaluate the clinical effects of memantine monotherapy (n = 38) in Alzheimer's disease (AD) patients using seven batteries to assess dementia at the baseline, at 3, 6, and 12 months. Additionally, we divided 163 AD patients treated with memantine into two subgroups depending on the baseline cognitive score of the Mini-Mental State Examination (MMSE): the MMSE OMS II showed that memantine monotherapy improved BPSD until 12 months. The higher baseline cognitive subgroup (MMSE ≥15) and the worse baseline BPSD subgroup were expected to show better effects with memantine.

    Understanding the prevalence of cattle producers' beliefs regarding disease reporting can help officials improve surveillance programs with passive data collection. A cross-sectional survey was conducted in Texas in 2008 and 2009 to determine beliefs about reporting cattle with clinical signs consistent with foot-and-mouth disease (FMD) either prior to (scenario 1) or during an on-going outbreak of FMD (scenario 2). Two questionnaires were developed and distributed to Texas cow-calf producers in order to evaluate their behavioral, control, and normative beliefs related to disease reporting. The context for each behavior was provided through the use of scenarios, and belief strength was measured using a 7-point Likert-like scale. Beliefs were compared across scenarios and demographic categories, and the effect of scenario on belief examined using ordinal logistic regression. Respondents agreed that reporting clinically suspect cases would have positive economic and emotional consequences; however, when an outbreak was known to be present, producers were less likely to agree with many of the positive outcomes of reporting. Important barriers to disease reporting indicated by producers included a lack of knowledge related to clinical signs of highly contagious cattle diseases and which cattle are at risk of contracting FMD. In general, beliefs about barriers to reporting did not differ based on scenario. Veterinarians and regulatory authorities were the groups perceived to most strongly expect disease reporting, regardless of the scenario. Risk education for producers related to clinical signs of reportable livestock diseases, post-reporting procedures, and an understanding of FMD introduction and spread may improve the reporting of cattle with clinical signs consistent with FMD.

    The design and analysis of cancer clinical trials with biomarker depend on various factors, such as the phase of trials, the type of biomarker, whether the used biomarker is validated or not, and the study objectives. In this article, we demonstrate the design and analysis of two Phase II cancer clinical trials, one with a predictive biomarker and the other with an imaging prognostic biomarker. Statistical testing methods and their sample size calculation methods are presented for each trial. We assume that the primary endpoint of these trials is a time to event variable, but this concept can be used for any type of endpoint.

    The increasing burden and the continued suboptimal outcomes for patients with heart failure underlines the importance of continued research to develop novel therapeutics for this disorder. This can only be accomplished with successful translation of basic science discoveries into direct human application through effective clinical trial design and execution that results in a substantially improved clinical course and outcomes. In this respect, phase II clinical trials play a pivotal role in determining which of the multitude of potential basic science discoveries should move to the large and expansive registration trials in humans. A critical examination of the phase II trials in heart failure reveals multiple shortcomings in their concept, design, execution, and interpretation. To further a dialogue regarding the challenges and potential for improvement and the role of phase II trials in patients with heart failure, the Food and Drug Administration facilitated a meeting on October 17th 2016 represented by clinicians, researchers, industry members, and regulators. This document summarizes the discussion from this meeting and provides key recommendations for future directions. PMID:28356300

    Full Text Available Aim: The present study was undertaken with the objectives to characterize, identify DNA polymorphism in cluster of differentiation 14 (CD14 gene in Karan Fries (KF cattle and to analyze association between genetic variants with incidence of clinical mastitis in National Dairy Research Institute (NDRI herd, Karnal. Materials and Methods: Genomic DNA was extracted using blood of randomly selected hundred KF lactating cattle by phenol-chloroform method. After checking its quality and quantity, polymerase chain reaction (PCR was carried out using reported primers to amplify 832 base pair region covering nucleotide base position number 1012 to 1843 (part of promoter, 5’UTR, exon 1, intron 1 and part of exon 2 of bovine CD14 gene. The PCR amplified target product was purified, sequenced and further ClustalW analysis was done to align edited sequence with reported Bos taurus sequence (EU148610.1. The restriction fragment length polymorphism (RFLP analysis was performed for each KF cow using HinfI restriction enzyme (RE. Cows were assigned genotypes obtained by PCR-RFLP analysis and association study was done using Chi-square (χ2 test. Results: After PCR amplification, DNA sequencing of amplicon confirmed the 832 bases covering 1012 to 1843 nucleotide base position of bovine CD14 gene. ClustalW multiple sequence alignment program for DNA revealed six nucleotide changes in KF cows at positions T1117D, T1239G, T1291C, G1359C, G1361A, and G1811A. Cows were also screened using PCR-RFLP with HinfI RE, which revealed three genotypes CC, CD and DD that differed significantly regarding mastitis incidence. Within CC genotype, 72.73% of cows were in a mastitis non-affected group whereas, those in CD and DD genotypes 69.44% and 60.38% respectively were mastitis affected. Conclusion: KF cows with allele C of CD14 gene were less susceptibility to mastitis compared with D allele.

    Mastitis of dairy cattle is one of the most frequently diagnosed diseases worldwide. The main etiological agents of mastitis are bacteria of the genus Streptococcus spp., in which several antibiotic resistance mechanisms have been identified. However, detailed studies addressing this problem have not been conducted in northeastern Poland. Therefore, the aim of our study was to analyze, on phenotypic and genotypic levels, the antibiotic resistance pattern of Streptococcus spp. isolated from clinical cases of mastitis from dairy cattle in this region of Poland. The research was conducted using 135 strains of Streptococcus (Streptococcus uberis, n = 53; Streptococcus dysgalactiae, n = 41; Streptococcus agalactiae, n = 27; other streptococci, n = 14). The investigation of the antimicrobial susceptibility to 8 active substances applied in therapy in the analyzed region, as well as a selected bacteriocin (nisin), was performed using the minimum inhibitory concentration method. The presence of selected resistance genes (n = 14) was determined via PCR. We also investigated the correlation between the presence of resistance genes and the antimicrobial susceptibility of the examined strains in vitro. The highest observed resistance of Streptococcus spp. was toward gentamicin, kanamycin, and tetracycline, whereas the highest susceptibility occurred toward penicillin, enrofloxacin, and marbofloxacin. Additionally, the tested bacteriocin showed high efficacy. The presence of 13 analyzed resistance genes was observed in the examined strains [gene mef(A) was not detected]. In most strains, at least one resistance gene, mainly responsible for resistance to tetracyclines [tet(M), tet(K), tet(L)], was observed. However, a relationship between the presence of a given resistance gene and antimicrobial susceptibility on the phenotypic level was not always observed.

    1990-04-01

    Tropical bovine theileriosis caused by Theileria annulata and transmitted by ticks of the genus Hyalomma may be controlled by one or more of the following methods: i) management, with particular emphasis on movement control; ii) vector control by application of acaricides, preventing transmission of disease; iii) treatment of clinical disease using specific chemotherapeutics; iv) immunization with live vaccines; and v) the use of cattle resistant to ticks or the disease. Of these the most important and effective control method is the use of a live cell culture vaccine attenuated by prolonged culture in vitro of mononuclear cells persistently infected with macroschizonts of T. annulata. This vaccine, used chiefly in susceptible taurine dairy cattle, can now be complemented by using novel chemotherapeutic naphthoquinones--parvaquone and buparvaquone--which are very effective in treatment of the clinical disease in these valuable cattle.

    AIM To determine the most commonly used words in the clinical histories of animals naturally infected with Theileria orientalis Ikeda type; whether these words differed between cases categorised by age, farm type or haematocrit (HCT), and if there was any clustering of the common words in relation to these categories. METHODS Clinical histories were transcribed for 605 cases of bovine anaemia associated with T. orientalis (TABA), that were submitted to laboratories with blood samples which tested positive for T. orientalis Ikeda type infection by PCR analysis, between October 2012 and November 2014. χ 2 tests were used to determine whether the proportion of submissions for each word was similar across the categories of HCT (normal, moderate anaemia or severe anaemia), farm type (dairy or beef) and age (young or old). Correspondence analysis (CA) was carried out on a contingency table of the frequency of the 28 most commonly used history words, cross-tabulated by age categories (young, old or unknown). Agglomerative hierarchical clustering, using Ward's method, was then performed on the coordinates from the correspondence analysis. RESULTS The six most commonly used history words were jaundice (204/605), lethargic (162/605), pale mucous membranes (161/605), cow (151/605), anaemia (147/605), and off milk (115/605). The proportion of cases with some history words differed between categories of age, farm type and HCT. The cluster analysis indicated that the recorded history words were grouped in two main clusters. The first included the words weight loss, tachycardia, pale mucous membranes, anaemia, lethargic and thin, and was associated with adult (pcluster included the words deaths, ill-thrift, calves, calf and diarrhoea, and was associated with young (pCluster analysis of words recorded in clinical histories submitted with blood samples from cases of TABA indicates that two potentially different disease syndromes were associated with T. orientalis Ikeda type

    The decision to treat a patient with stage II colon cancer with adjuvant chemotherapy can be challenging. Although the benefit of treatment is clear in most patients with stage III disease, the decision to provide chemotherapy after surgical resection in stage II disease must be made on an individual basis. Several trials have demonstrated the small but absolute benefits of receiving adjuvant chemotherapy for stage II colon cancer for disease-free survival and overall survival. In an attempt to better understand the role of chemotherapy, several studies were performed that identified high-risk characteristics that can be used prognostically and predictively to aid in the clinical decision making process. ASCO, the National Comprehensive Cancer Network, and the European Society of Medical Oncology have published guidelines describing these high-risk characteristics. Since then, several other molecular markers have emerged that may offer more information on a given patient's risk for recurrence. The decision to treat a patient with stage II colon cancer must be made on an individual basis, considering the risks and benefits of treatment. In this short review, we will present the available evidence and offer possible directions for future study.

    Laryngeal cleft (LC) is a rare congenital anomaly manifesting in a variety of symptoms, including swallowing disorders and aspirations, dyspnea, stridor and hoarseness. The mild forms (types I-II) may be underdiagnosed, leading to protracted symptomatology and morbidity. To evaluate the diagnostic process, clinical course, management and outcome in children with type I-II laryngeal clefts. We conducted a retrospective case analysis for the years 2005-2012 in a tertiary referral center. Seven children were reviewed: five boys and two girls ranging in age from birth to 5 years. The most common presenting symptoms were cough, aspirations and pneumonia. Evaluation procedures included fiber-optic laryngoscopy (FOL), direct laryngoscopy (DL) and videofluoroscopy. Other pathologies were seen in three children. Six children underwent successful endoscopic surgery and one child was treated conservatively. The postoperative clinical course was uneventful in most of the cases. Types I-II LC should be considered in the differential diagnosis of children presenting with protracted cough and aspirations. DL is crucial for establishing the diagnosis. Endoscopic surgery is safe and should be applied promptly when conservative measures fail.

    Corridor disease is an acute, fatal disease of cattle caused by buffalo-adapted Theileria parva. This is a nationally controlled disease in South Africa and strict control measures apply for the movement of buffalo, which includes mandatory testing for the presence of T. parva and other controlled diseases. Accurate diagnosis of the T. parva carrier state in buffalo using the official real-time hybridization PCR assay (Sibeko et al. 2008), has been shown to be affected by concurrent infection with T. sp. (buffalo)-like parasites. We describe the Hybrid II assay, a real-time hybridization PCR method, which compares well with the official hybridization assay in terms of specificity and sensitivity. It is, however, not influenced by mixed infections of T. sp. (buffalo)-like parasites and is as such a significant improvement on the current hybridization assay.

  9. CATTLE FEEDER BEHAVIOR AND FEEDER CATTLE PLACEMENTS

    OpenAIRE

    Kastens, Terry L.; Schroeder, Ted C.

    1994-01-01

    Cattle feeders appear irrational when they place cattle on feed when projected profit is negative. Long futures positions appear to offer superior returns to cattle feeding investment. Cattle feeder behavior suggests that they believe a downward bias in live cattle futures persists and that cattle feeders use different expectations than the live cattle futures market price when making placement decisions. This study examines feeder cattle placement determinants, comparing performance of expec...

    The present study aimed to compare mitochondrial diversity among Balkan Neolithic/Chalcolithic cattle and present day Shorthorn Rhodopean cattle (Busha) to throw a new insight into European cattle domestication. The results showed that both ancient- and present-day samples belonged to the macrohaplogroup T. From the 28 sequences (8 ancient and 20 modern), the T1 and T2 haplogroup represent about 3.6% (1/28; 1/28). The T3 haplogroup was with the highest frequency - 57% (16/28). Based on the SNPs on 16057A and 16133C, the new T6 haplogroup was proposed. This haplogroup represents 75% from the ancient and 20% from the present day Bulgarian brachicerous cattle population. The survey in GenBank data base did not find a similar motif, except for the recent Serbian Busha cattle. Overall, these results showed that: (i) The newly named T6 haplogroup is Balkan specific; (ii) The T6 haplogroup survives in present day Bulgarian rhodopean cattle; (iii) The Balkan brachicerous cattle is the oldest European cattle breed.

    2004-09-15

    A description of the clinical features of Majewski osteodysplastic primordial dwarfism type II (MOPD II) is presented based on 58 affected individuals (27 from the literature and 31 previously unreported cases). The remarkable features of MOPD II are: severe intrauterine growth retardation (IUGR), severe postnatal growth retardation; relatively proportionate head size at birth which progresses to true and disproportionate microcephaly; progressive disproportion of the short stature secondary to shortening of the distal and middle segments of the limbs; a progressive bony dysplasia with metaphyseal changes in the limbs; epiphyseal delay; progressive loose-jointedness with occasional dislocation or subluxation of the knees, radial heads, and hips; unusual facial features including a prominent nose, eyes which appear prominent in infancy and early childhood, ears which are proportionate, mildly dysplastic and usually missing the lobule; a high squeaky voice; abnormally, small, and often dysplastic or missing dentition; a pleasant, outgoing, sociable personality; and autosomal recessive inheritance. Far-sightedness, scoliosis, unusual pigmentation, and truncal obesity often develop with time. Some individuals seem to have increased susceptibility to infections. A number of affected individuals have developed dilation of the CNS arteries variously described as aneurysms and Moya Moya disease. These vascular changes can be life threatening, even in early years because of rupture, CNS hemorrhage, and strokes. There is variability between affected individuals even within the same family.

    2008-01-01

    Full Text Available A total of 51 cases of bovine clinical mastitis in Sulaimani district were investigated for their bacteriological causative agents; 76 milk samples were cultured on primary and selective media and the isolated bacteria were tested for their susceptibility to antimicrobial agents used in commercial intramammary infusion products. Eighty two bacterial isolates were obtained and further identified using biochemical tests. Escherichia coli was the most common bacteria followed by Staphylococcus aureus, Streptococcus agalactia and coagulase–negative staphylococci. Two other bacterial species (Pseudomonas aeruginosa and Streptococcucs uberis were also isolated but in a lower proportion. Antibacterial susceptibility testing showed that the use of florfenicol, cephalexin and gentamicin may be useful for the treatment of clinical mastitis cases in cows.

    In quarter milk samples from 2,492 randomly sampled cows that were selected without regard to their current or previous udder health status, the relationships between the following outcome variables were studied: treatment of clinical mastitis; the joint event of either treatment or culling for mastitis; culling for all reasons; culling specifically for mastitis; and the covariates of positive milk culture for Staphylococcus aureus, Streptococcus spp., and coagulase-negative Staphylococcus spp., or other pathogens, or of negative culture for mastitis pathogens. Microbiological diagnoses were assigned at the cow level, and altogether 3,075 diagnoses were related to the outcome variables. The relation between the absence of pathogens and rich (>1,500 cfu/mL of milk) or sparse (mastitis was greater for cows diagnosed with Staph. aureus compared with cows with no pathogens in all analyses. Cows with sparse growth of Staph. aureus upon microbiological analysis were more likely to be treated for clinical mastitis, and cows with rich growth of the bacteria experienced a higher overall risk of culling when the models adjusted for cow composite milk somatic cell count. No difference between rich and sparse growth of Staph. aureus was found when mastitis was defined as the joint event of either culling for mastitis or treatment of clinical mastitis, and when the relationship with culling specifically for mastitis was assessed. The combined outcome of treatment and culling for mastitis was related to a positive diagnosis of Strep. spp. after cow composite milk somatic cell count was omitted from the model. Presence of Streptococcus spp. was also related to culling specifically for mastitis, whereas culling for all reasons and treatment of clinical mastitis was not related to a positive culture of Strep. spp. Presence of coagulase-negative Staph. spp. or other pathogens was not associated with either of the outcome variables.

    Full Text Available The aim of the study was to evaluate the presence of Mycoplasma bovis infection and co-infections with other Mycoplasma spp. infections in cattle. The tested population was one in the eastern region of Poland containing 66 dairy cows and 23 calves showing different clinical signs and suffering from pneumonia, mastitis, and arthritis. The incidence of M. bovis in co-infections with other Mycoplasma spp. was examined using serological traditional mycoplasma culture methods, and the molecular methods - PCR and polymerase chain reaction/denaturing gradient gel electrophoresis (PCR/DGGE. The PCR/DGGE method for detecting Mycoplasma spp. in cattle was used for the first time in Poland. The seroprevalence of M. bovis in the affected cattle herds in the eastern region of Poland was 47.8% in calves and 19.7% in dairy cows. The direct detection and identification of M. bovis from nasopharyngeal swabs by PCR revealed that 56.5% of calves were positive, but all of the dairy cows were negative. The PCR/DGGE identified eight (34.8% instances of M. arginini and eight (26.1% instances of M. bovirhinis co-infecting with M. bovis in ten calves. The seroprevalence of M. bovis in the tested population was 33.7%. Any future attempts to control mycoplasma infections require an insight into the current epidemiological situation of M. bovis infection and its relationship to other mycoplasmas in causing clinical disease in cattle. Using these diagnostic methods we have demonstrated that mycoplasmal infections are often caused by multiple species of Mycoplasma and not just the primary M. bovis pathogen.

    2017-04-01

    This review will provide an overview of the microcephalic primordial dwarfism (MPD) class of disorders and provide the reader comprehensive clinical review with suggested care guidelines for patients with microcephalic osteodysplastic primordial dwarfism, type II (MOPDII). Over the last 15 years, significant strides have been made in the diagnosis, natural history, and management of MOPDII. MOPDII is the most common and well described form of MPD. The classic features of the MPD group are severe pre- and postnatal growth retardation, with marked microcephaly. In addition to these features, individuals with MOPDII have characteristic facies, skeletal dysplasia, abnormal dentition, and an increased risk for cerebrovascular disease and insulin resistance. Biallelic loss-of-function mutations in the pericentrin gene cause MOPDII, which is inherited in an autosomal recessive manner.

    Information related to mastitis risk factors is useful for the design and implementation of clinical mastitis (CM) control programs. The first objective of our study was to model the risk of CM under Brazilian conditions, using cow-specific risk factors. Our second objective was to explore which risk factors were associated with the occurrence of the most common pathogens involved in Brazilian CM infections. The analyses were based on 65 months of data from 9,789 dairy cows and 12,464 CM cases. Cow-specific risk factors that could easily be measured in standard Brazilian dairy farms were used in the statistical analyses, which included logistic regression and multinomial logistic regression. The first month of lactation, high somatic cell count, rainy season and history of clinical mastitis cases were factors associated with CM for both primiparous and multiparous cows. In addition, parity and breed were also associated risk factors for multiparous cows. Of all CM cases, 54% showed positive bacteriological culturing results from which 57% were classified as environmental pathogens, with a large percentage of coliforms (35%). Coagulase-negative Staphylococcus (16%), Streptococcus uberis (9%), Streptococcus agalactiae (7%) and other Streptococci (9%) were also common pathogens. Among the pathogens analyzed, the association of cow-specific risk factors, such as Zebu breed (OR=5.84, 95%CI 3.77-10.77) and accumulated history of SCC (1.76, 95%CI 1.37-2.27), was different for CM caused by Coagulase-negative Staphylococcus and S. agalactiae in comparison to CM caused by coliforms. Our results suggest that CM control programs in Brazil should specially consider the recent history of clinical mastitis cases and the beginning of the lactations, mainly during the rainy season as important risk factor for mastitis.

  1. Mediation analysis to estimate direct and indirect milk losses due to clinical mastitis in dairy cattle.

    Science.gov (United States)

    Detilleux, J; Kastelic, J P; Barkema, H W

    2015-03-01

    Milk losses associated with mastitis can be attributed to either effects of pathogens per se (i.e., direct losses) or effects of the immune response triggered by intramammary infection (indirect losses). The distinction is important in terms of mastitis prevention and treatment. Regardless, the number of pathogens is often unknown (particularly in field studies), making it difficult to estimate direct losses, whereas indirect losses can be approximated by measuring the association between increased somatic cell count (SCC) and milk production. An alternative is to perform a mediation analysis in which changes in milk yield are allocated into their direct and indirect components. We applied this method on data for clinical mastitis, milk and SCC test-day recordings, results of bacteriological cultures (Escherichia coli, Staphylococcus aureus, Streptococcus uberis, coagulase-negative staphylococci, Streptococcus dysgalactiae, and streptococci other than Strep. dysgalactiae and Strep. uberis), and cow characteristics. Following a diagnosis of clinical mastitis, the cow was treated and changes (increase or decrease) in milk production before and after a diagnosis were interpreted counterfactually. On a daily basis, indirect changes, mediated by SCC increase, were significantly different from zero for all bacterial species, with a milk yield decrease (ranging among species from 4 to 33g and mediated by an increase of 1000 SCC/mL/day) before and a daily milk increase (ranging among species from 2 to 12g and mediated by a decrease of 1000 SCC/mL/day) after detection. Direct changes, not mediated by SCC, were only different from zero for coagulase-negative staphylococci before diagnosis (72g per day). We concluded that mixed structural equation models were useful to estimate direct and indirect effects of the presence of clinical mastitis on milk yield. Copyright © 2015 Elsevier B.V.

    Full Text Available Abstract Background The majority of atypical bovine spongiform encephalopathy (BSE cases so far identified worldwide have been detected by active surveillance. Consequently the volume and quality of material available for detailed characterisation is very limiting. Here we report on a small transmission study of both atypical forms, H- and L-type BSE, in cattle to provide tissue for test evaluation and research, and to generate clinical, molecular and pathological data in a standardised way to enable more robust comparison of the two variants with particular reference to those aspects most relevant to case ascertainment and confirmatory diagnosis within existing regulated surveillance programmes. Results Two groups of four cattle, intracerebrally inoculated with L-type or H-type BSE, all presented with a nervous disease form with some similarities to classical BSE, which progressed to a more dull form in one animal from each group. Difficulty rising was a consistent feature of both disease forms and not seen in two BSE-free, non-inoculated cattle that served as controls. The pathology and molecular characteristics were distinct from classical BSE, and broadly consistent with published data, but with some variation in the pathological characteristics. Both atypical BSE types were readily detectable as BSE by current confirmatory methods using the medulla brain region at the obex, but making a clear diagnostic distinction between the forms was not consistently straightforward in this brain region. Cerebellum proved a more reliable sample for discrimination when using immunohistochemistry. Conclusions The prominent feature of difficulty rising in atypical BSE cases may explain the detection of naturally occurring cases in emergency slaughter cattle and fallen stock. Current confirmatory diagnostic methods are effective for the detection of such atypical cases, but consistently and correctly identifying the variant forms may require modifications to

    The use of corneal anaesthesia is necessary for a range of clinical purposes. Therefore, we assessed and compared the efficacy of corneal anaesthesia after application of 0.4% oxybuprocaine hydrochloride and 0.5% proparacaine hydrochloride ophthalmic solution in clinically normal cattle. The 24 clinically normal cows were allocated into two groups. Cows in group 1 (n = 12) received 0.2 mL of 0.4% oxybuprocaine hydrochloride with fluorescein ophthalmic solution in one eye and 0.2 mL of sterile saline (0.9% NaCl) with fluorescein in the contralateral eye (control). Group 2 (n = 12) received 0.2 mL of 0.4% oxybuprocaine hydrochloride with fluorescein ophthalmic solution in one eye and 0.2 mL of 0.5% proparacaine hydrochloride with fluorescein in the contralateral eye (control). In each group, corneal touch threshold was determined by Cochet-Bonnet aesthesiometer for both eyes immediately prior to topical administration of solutions, at 1 min and 5 min after administration of topical solutions and every 5 min thereafter for a total of 75 min. Significant corneal anaesthesia was noted immediately following topical application of both oxybuprocaine and proparacaine as compared with controls, with maximal corneal anaesthesia noted 1 min after administration. Both oxybuprocaine and proparacaine produced significant corneal anaesthesia for the duration of the 75-min study. Neither oxybuprocaine hydrochloride nor proparacaine hydrochloride treatment resulted in visible adverse effects. There are limited data available demonstrating the efficacy and duration of corneal anaesthetic agents in cattle. Both oxybuprocaine hydrochloride and proparacaine hydrochloride should be considered practical options for providing corneal anaesthesia in cattle in a clinical setting. © 2016 Australian Veterinary Association.

    Dermatophilosis is a contagious disease of high economic importance. The study assessed knowledge/awareness and clinical burden of and mitigation measures practised against clinical bovine dermatophilosis in pastoral herds of North-Central Nigeria and associated socio-cultural factors that predisposed to its occurrence in herds. A cross-sectional survey was conducted between October 2015 and September 2016. Questionnaires were administered on pastoralists and clinical assessment of cattle with gross pathological lesions indicative of dermatophilosis conducted. Associated economic impact was estimated. All 384 selected pastoralists participated in the survey. The majorities of nomadic (97.4%) and sedentary (68.2%) pastoralists significantly (p Culture of giving out cattle as gift or payment for dowry was more likely (OR 28.56; 95% CI 15.64, 52.12) to influence dermatophilosis occurrence in herds. Overall clinical dermatophilosis burden was 3.6% (95% CI 3.46, 3.80) and the annual economic impact was estimated at 908,463.9 USD. This study has given an idea to the status of pastoralists' levels of awareness about dermatophilosis in Nigeria, which can be harnessed by policy makers to develop its mitigation measures. Significant influence of pastoralists' socio-cultural activities on dermatophilosis occurrence in herds was identified. Surveillance and control programmes towards dermatophilosis that take these factors into consideration will be beneficial to the herders.

    2004-01-01

    Full Text Available Background. Evidence-based medicine employs systematic searching, evaluation and use of current research findings as the basis for clinical decision-making. However, there are some problems and uncertainties hindering introduction and spreading of the use of the method in clinical practice. Physicians often have no time for literature searching and for use of the method in practice. For certain questions in clinical practice there are no answers in medical literature. Most of the evidences in medical literature are only available in English. Introduction of the method is hampered also by the fact that clinical decision-making is complex and does not allow procedures prescribed in advance. Rigidity and universality of decisions resulting from the evidence may appear impersonal and may affect the relationship between the physician and the patient. Trends towards evidence based medicine are followed also by big multinational pharmaceutical corporations. They carry out large and expensive clinical trials using the results for promotional purposes. In this way, they get the competitive advantage and influence the objectivity of physicians’ clinical decision-making.Conclusions. With introduction of evidence based medicine into clinical practice physicians acquire new information and use a new form of continuing education by following new developments in their field. This way, new findings from medical literature get into clinical practice faster and more efficiently. In addition, physicians get more professional satisfaction and quality in clinical practice is higher.

    We report on a 2 9/12-year-old boy with disproportionate short stature, microcephaly, subtle craniofacial dysmorphisms, and generalized skeletal dysplasia, who developed a left hemiparesis. Brain neuroimaging disclosed a complex cerebral vascular anomaly (CVA) with stenosis of the right anterior cerebral artery and telangiectatic collateral vessels supplying the cerebral cortex, consistent with moyamoya disease. Based on clinical and skeletal features, a diagnosis of Majewski osteodysplastic primordial dwarfism type II (MOPD II) was established. Review of 16 published patients with CVA affected by either Seckel syndrome or MOPD II suggested that CVA is preferentially associated to the latter subtype affecting about 1/4 of the patients. 2005 Wiley-Liss, Inc.

    Directory of Open Access Journals (Sweden)

    2011-07-01

    Full Text Available Urotensin-II (UII, which binds to its receptor UT, plays an important role in the heart, kidneys, pancreas, adrenal gland and CNS. In the vasculature, it acts as a potent endothelium-independent vasoconstrictor and endothelium-dependent vasodilator. In disease states, this constriction-dilation equilibrium is disrupted. There is an upregulation of the UII system in heart disease, metabolic syndrome and kidney failure. The increase in UII release and UT expression suggest that UII system may be implicated in the pathology and pathogenesis of these diseases by causing an increase in ACAT-1 activity leading to SMC proliferation and foam cell infiltration, insulin resistance (DMII, as well as inflammation, high blood pressure and plaque formation. Recently, UT antagonists such as SB-611812, palosuran, and most recently a piperazino-isoindolinone based antagonist have been developed in the hope of better understanding the UII system and treating its associated diseases.

    Here we present the results of a study performed on 59 patients affected by Waardenburg syndrome (WS), 30 with the I variant, 21 having the type II, and 8 of them being isolated cases without telecanthus. These patients belong to 37 families; the main contributions and conclusions are based on the detailed study of 25 of these families, examined using standard procedures. All patients were examined as to the presence of eight cardinal signs important for the diagnosis of the condition; from each patient, from many of his/her normal relatives, and from a control sample of 300 normal individuals stratified by age and sex, 23 different craniofacial measurements were obtained. We also estimated, using our own data as well those collected from the literature, the frequencies of the cardinal signs, based on a total sample of 461 affected individuals with WSI and 121 with WSII. In order to originate discriminant functions to separate individuals affected by one of the two variants, both metric (from craniofacial measurements) as well as categoric data (based on the frequencies of the cardinal signs or symptoms) were used. Discriminant analysis based on the frequency of the eight cardinal signs can improve the separation of WSI patients without telecanthus from those presenting the variant II. We present also a Table with the conditional probabilities favoring the diagnosis of WSI for suspect subjects without telecanthus and any combination of the other seven signs/symptoms. The discriminant function based on the four ocular measurements (inner and outer intercanthal, interpupillary, and inferior lacrymal distances), on the other side, perfectly classifies patients affected by one of the variants of WS, the same taking place when the average values of the W index of all affected individuals per family are used. The discriminant function based solely in the individual W index values of patients correctly classifies 93% of WSII subjects, but only 60% of the patients with the

    The Multiparameter Intelligent Monitoring in Intensive Care II (MIMIC-II) database is a free, public resource for intensive care research. The database was officially released in 2006, and has attracted a growing number of researchers in academia and industry. We present the two major software tools that facilitate accessing the relational database: the web-based QueryBuilder and a downloadable virtual machine (VM) image. QueryBuilder and the MIMIC-II VM have been developed successfully and are freely available to MIMIC-II users. Simple example SQL queries and the resulting data are presented. Clinical studies pertaining to acute kidney injury and prediction of fluid requirements in the intensive care unit are shown as typical examples of research performed with MIMIC-II. In addition, MIMIC-II has also provided data for annual PhysioNet/Computing in Cardiology Challenges, including the 2012 Challenge "Predicting mortality of ICU Patients". QueryBuilder is a web-based tool that provides easy access to MIMIC-II. For more computationally intensive queries, one can locally install a complete copy of MIMIC-II in a VM. Both publicly available tools provide the MIMIC-II research community with convenient querying interfaces and complement the value of the MIMIC-II relational database.

    Prescribed drug use for bipolar disorder type I and II in clinical practice Practice guidelines based on available evidence and clinical consensus are available for the treatment of bipolar disorder. We surveyed to which extent those guidelines are implemented in clinical practice in Sweden. We analysed pharmacological treatment in patients with bipolar disorder in 2015 using the national quality register for bipolar disorder (BipoläR). We compared bipolar disorder type I (BDI) with type bipolar disorder type II (BDII). The vast majority of patients were prescribed a mood stabilizer either as monotherapy or as a part of combination therapy (BDI 87%, BDII 83%, pbipolar disorder.

    Pain at the ulnar aspect of the wrist is a diagnostic challenge for hand surgeons and radiologists due to the small and complex anatomical structures involved. In this article, imaging modalities including radiography, arthrography, ultrasound (US), computed tomography (CT), CT arthrography, magnetic resonance (MR) imaging, and MR arthrography are compared with regard to differential diagnosis. Clinical imaging findings are reviewed for a more comprehensive understanding of this disorder. Treatments for the common diseases that cause the ulnar-sided wrist pain including extensor carpi ulnaris (ECU) tendonitis, flexor carpi ulnaris (FCU) tendonitis, pisotriquetral arthritis, triangular fibrocartilage complex (TFCC) lesions, ulnar impaction, lunotriquetral (LT) instability, and distal radioulnar joint (DRUJ) instability are reviewed.

    This experiment was conducted to determine the effects of cassava bioethanol by-product (CEP) and crude palm oil (CPO) on the carcass characteristics and meat quality of yearling heifer cattle. Eighteen crossbred Brahman × Thai heifers were randomly allotted to 2 × 3 factorial arrangement consisting of two levels of CEP (15 or 30 %, LCEP or HCEP) and 3 levels of CPO (0, 2, and 4 %). The results obtained showed that lean meat was greater (P < 0.05) in HCEP-fed cattle, but bone percentage and lean/bone ratio were less (P < 0.05) than LCEP-fed cattle. Carcass fat (P < 0.05) and fat content (P < 0.01) were significantly increased with levels of dietary CPO. Diets with 4 % CPO supplementation had better effects on redness (a*, P < 0.01) and chroma (C*, P < 0.001) values. In conclusion, up to 30 % CEP can be used to improve lean carcass and 4 % CPO can improve the redness of the meat.

    This study reports on research undertaken to identify the skills and competencies of forensic psychiatric nurses working in secure psychiatric services in the UK. The rationale for this research is the lack of clarity in the role definition of nurses working in these environments and the specific content that may underscore the curriculum for training forensic nurses. Over 3300 questionnaires were distributed to forensic psychiatric nurses, non-forensic psychiatric nurses and other disciplines and information obtained on (1) the perceived clinical problems that give forensic nurses the most difficulty; (2) the skills best suited to overcome those problems; and (3) the priority aspects of clinical nursing care that needs to be developed. A 35% response rate was obtained with 1019 forensic psychiatric nurses, 110 non-forensic psychiatric nurses and 43 other disciplines. The results highlighted a 'top ten' list of main problems with possible solutions and main areas for development. The conclusions drawn include a focus on skills and competencies regarding the management of personality disorders and the management of violence and aggression.

    Cattle feeders appear irrational when they place cattle on feed when projected profits are negative. Long futures positions appear to offer superior returns to cattle feeding investment. Cattle feeder behavior suggests that they believe a downward bias in live cattle futures persists and that cattle feeders use different information than the live cattle futures market price when making placement decisions. This paper examines feeder cattle placement determinants and compares performance of ex...

    Polyetheretherketone (PEEK) is one of the up-to-date organic polymer thermoplastics with applications in orthopaedics and trauma medicine. This study presents a detailed analysis of its tests and applications in clinical medicine. A wide range of PEEK modifications and composites are commercially available, e.g., PEEK-Classix, PEEK-Optima, Endolign and Motis. They differ in their physical properties, which makes them suitable for different applications. Other forms, so-called PEEK bioactive composites, contain beta-tricalcium phosphate and hydroxyapatite. Research in this field is also concerned with the surface finish of this polymer thermoplastic and involves macroporous titanium and hydroxyapatite layers, or treatment with laser for an exactly defined surface structure. The clinical applications of PEEK and its composites include, in addition to components for spinal surgery, osteosynthesis plates, screws, intramedullary nails or external fixators, which are implants still at the stage of prototypes. In this review, attention is paid to the use of PEEK thermoplastics for joint replacement. Mid-term studies involving hundreds of patients have shown that, for instance, the VerSys Epoch Fullcoat Hip System (Zimmer) has a markedly lower stress-shielding effect. Carbon fibre-reinforced (CFR-PEEK) composites are used to make articulating components for total hip replacement. Their convenient properties allow for production of much thinner liners and an enlargement of the femoral head diameter, thus reducing the wear of joint implants. CFR-PEEK composites are particularly effective for hip resurfacing in which the Mitch PCR (Stryker) acetabular component has been used with good results. The MOTIS polymer acetabular cup (Invibio Ltd.) is another example. Further PEEK applications include the construction of finger-joint prostheses (Mathys AG), suture anchors (Stryker) and various kinds of augmentations (Medin). Based on the information obtained, the authors suggest

    Dairy cattle in two commercial Holstein herds were randomly selected to be vaccinated twice with J5, at approximately 60 days and 28 days before the expected calving date, or to be untreated controls. Based on whether milk production changed following clinical mastitis or whether cows were culled or died within 30 days after onset, 51 mastitis cases were classified as severe or mild. J5-specific antibody responses were evaluated by enzyme-linked immunosorbent assay of all 32 severe and 19 mild cases. The amounts of J5-specific immunoglobulin M (IgM), IgG1, and IgG2 antibodies in sera from the 27 J5 vaccinates were compared with those of the 24 controls. At drying off (before J5 vaccination), all cows had similar amounts of J5-specific antibody. Immediately after calving (approximately 28 days after the second vaccination), J5 vaccinates had significantly higher production of J5-specific IgG1 and IgG2 than controls. When cows were tested following clinical mastitis, none of the three antibody classes differed significantly between the controls and the vaccinates. Vaccinates that contracted Escherichia coli mastitis had 75% less milk loss than controls. The cows that contracted clinical mastitis later in lactation, the unvaccinated controls, and those infected with E. coli had more milk loss following mastitis. The hazards of being culled for all reasons and of being culled for mastitis were significantly lower for J5 vaccinates. Vaccination with J5 was associated with protection against milk production loss and culling following clinical mastitis, and it was also significantly associated with changes in J5-specific IgM, IgG1, and IgG2 antibodies in sera of vaccinated cows.

    Full Text Available Ω-3 unsaturated fatty acids are compounds belonging to the group of essential fatty acids (EFAs. The history of the discovery of EFAs dates back to the 1930s of the twentieth century, however, growing interest in ω-3 EFAs in the context of mental health has been observed since the year 2000. In view of their multidirectional action, these compounds are a promising form of adjunctive therapy of many illnesses, including psychiatric disorders. The present article aims to review the literature on the clinical applicability of ω-3 EFAs in treating schizophrenia. We present the results of preclinical studies in this area and the mechanisms of ω-3 EFAs action discussed by the authors. The randomized controlled trials (RCTs evaluating the possibility of using ω-3 EFAs in schizophrenia are characterized in detail. The results of the tests are not clear, which may result from the methodological diversity of interventions made. Ω-3 EFAs seem to be a promising form of adjunctive therapy of schizophrenia. Further research is needed, which will allow for defining groups of patients in which intervention will bring the expected results.

  8. Ocular toxoplasmosis II: clinical features, pathology and management

    2014-01-01

    The term, ocular toxoplasmosis, refers to eye disease related to infection with the parasite, Toxoplasma gondii. Recurrent posterior uveitis is the typical form of this disease, characterized by unilateral, necrotizing retinitis with secondary choroiditis, occurring adjacent to a pigmented retinochoroidal scar and associated with retinal vasculitis and vitritis. Multiple atypical presentations are also described, and severe inflammation is observed in immunocompromised patients. Histopathological correlations demonstrate focal coagulative retinal necrosis, and early in the course of the disease, this inflammation is based in the inner retina. For typical ocular toxoplasmosis, a diagnosis is easily made on clinical examination. In atypical cases, ocular fluid testing to detect parasite DNA by polymerase chain reaction or to determine intraocular production of specific antibody may be extremely helpful for establishing aetiology. Given the high seroprevalence of toxoplasmosis in most communities, serological testing for T. gondii antibodies is generally not useful. Despite a lack of published evidence for effectiveness of current therapies, most ophthalmologists elect to treat patients with ocular toxoplasmosis that reduces or threatens to impact vision. Classic therapy consists of oral pyrimethamine and sulfadiazine, plus systemic corticosteroid. Substantial toxicity of this drug combination has spurred interest in alternative antimicrobials, as well as local forms of drug delivery. At this time, however, no therapeutic approach is curative of ocular toxoplasmosis. PMID:22712598

    The Argus II Retinal Prosthesis System (Second Sight Medical Products, Inc, Sylmar, CA) was developed to restore some vision to patients blind as a result of retinitis pigmentosa (RP) or outer retinal degeneration. A clinical trial was initiated in 2006 to study the long-term safety and efficacy of the Argus II System in patients with bare or no light perception resulting from end-stage RP. Prospective, multicenter, single-arm clinical trial. Within-patient controls included the nonimplanted fellow eye and patients' native residual vision compared with their vision with the Argus II. Thirty participants in 10 centers in the United States and Europe. The worse-seeing eye of blind patients was implanted with the Argus II. Patients wore glasses mounted with a small camera and a video processor that converted images into stimulation patterns sent to the electrode array on the retina. The primary outcome measures were safety (the number, seriousness, and relatedness of adverse events) and visual function, as measured by 3 computer-based, objective tests. Secondary measures included functional vision performance on objectively scored real-world tasks. Twenty-four of 30 patients remained implanted with functioning Argus II Systems at 5 years after implantation. Only 1 additional serious adverse event was experienced after the 3-year time point. Patients performed significantly better with the Argus II on than off on all visual function tests and functional vision tasks. The 5-year results of the Argus II trial support the long-term safety profile and benefit of the Argus II System for patients blind as a result of RP. The Argus II is the first and only retinal implant to have market approval in the European Economic Area, the United States, and Canada. Copyright © 2016 American Academy of Ophthalmology.

    Full Text Available Cattle are our most important livestock species because of their production and role in human culture. Many breeds that differ in appearance, performance and environmental adaptation are kept on all inhabited continents, but the historic origin of the diverse phenotypes is not always clear. We give an account of the history of cattle by integrating archaeological record and pictorial or written sources, scarce until 300 years ago, with the recent contributions of DNA analysis. We describe the domestication of their wild ancestor, migrations to eventually all inhabited continents, the developments during prehistory, the antiquity and the Middle Ages, the relatively recent breed formation, the industrial cattle husbandry in the Old and New World and the current efforts to preserve the cattle genetic resources. Surveying the available information, we propose three main and overlapping phases during the development of the present genetic diversity: (i domestication and subsequent wild introgression; (ii natural adaptation to a diverse agricultural habitat; and (iii breed development.

    This study was performed to investigate the effect of periparturient body condition score on the occurrence of clinical endometritis and postpartum resumption of ovarian activity in dairy cows. Eighty-seven lactating Holstein cows, fed with a total mixed ration diet, were included into the study. Body condition scoring (using a 5-point scale with quarter-point divisions) was performed by the same investigator using the visual technique every 2 weeks, from 2 weeks before until 6 weeks after calving. Palpation of the reproductive tract and ultrasonographic assessment of ovaries for detection of corpus luteum using a rectal linear probe was also performed at 2, 4, and 6 weeks after calving. Cows with clinical endometritis had significantly lower body condition score (BCS) than normal cows at all weeks pre- and postcalving, and cows that did not ovulate until 45 days after calving had a significantly lower BCS pre- and postpartum. Cows that did not ovulate until 45 days after calving also lost more BCS from 2 weeks before to 4 weeks after calving. Besides, first ovulation after calving take occurred later in cows with clinical endometritis compared to normal cows (P < 0.05). In conclusion, low BCS is a risk factor for postpartum endometritis and delayed cyclicity in dairy cows. BCS loss from dry-off to early lactation and occurrence of clinical endometritis can significantly affect postpartum ovarian activity.

    Neonatal jaundice is a very frequent condition that occurs in approximately 50-70% of term or near-term (>35 GA) babies in the 1st week of life. In some cases, a high bilirubin blood level can lead to kernicterus. There is no consensus for the management of neonatal jaundice and few countries have published national clinical practice guidelines for the management of neonatal jaundice. The aim of this study was to assess the quality of these guidelines. We conducted a systematic review of the literature for national clinical practice guidelines for the management of neonatal jaundice in term or near-term babies. Four independent reviewers assessed the quality of each guideline using the AGREE II evaluation. For each of the clinical practice guidelines, the management modalities were analyzed (screening, treatment, follow-up, etc.). Seven national clinical practice guidelines were found (South Africa, USA AAP, UK NICE, Canada, Norway, Switzerland, and Israel). The AGREE II score showed widespread variation regarding the quality of these national guidelines. There was no major difference between the guidelines concerning the clinical management of these babies. The NICE guideline is the most valuable guideline regarding the AGREE II score. NICE showed that, despite a strong and rigorous methodology, there is no evidenced-based recommended code of practice (RCP). Comparing RCPs, we found no major differences. The NICE guideline showed the best quality. The AGREE II instrument should be used as a framework when developing clinical practice guidelines to improve the quality of the future guideline. In France, a national guideline is needed for a more standardized management of neonatal jaundice. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

  19. [New intensifying screens in clinical radiology. II. Examinations in clinical practice].

    A clinically applicable procedure for testing new intensifying rare earth screens, as well as the special Siemens' screen is described. The results are related to universal screens. The film-screen combination alpha 4XD (gadolinium oxysulphide with normal, green sensitive film) results in a reduction of radiation dose to half with detail comparable with universal screens. The Siemens' special screen has similar advantages. Screens with a higher intensification factor and reduction of the mAs to one sixth results in loss of detail. This does not necessarily reduce their clinical use if they are used for appropriate purposes. The results of this clinically orientated technique agreed well with physically objective methods using lead grids. The advantages of the new screens are discussed in terms of their practical application.

    In this paper we sought to reproduce, as a computational retrospective study in an EHR database (MIMIC-II), a recent large prospective clinical study: the 2013 publication, by the Japanese Association for Acute Medicine (JAAM), about disseminated intravascular coagulation, in the journal Critical Care (PMID: 23787004). We designed in SQL and Java a set of electronic phenotypes that reproduced the study's data sampling, and used R to perform the same statistical inference procedures. All produced source code is available online at https://github.com/fabkury/paamia2015. Our program identified 2,257 eligible patients in MIMIC-II, and the results remarkably agreed with the prospective study. A minority of the needed data elements was not found in MIMIC-II, and statistically significant inferences were possible in the majority of the cases.

    The aim of this study was to investigate whether quantitative trait loci (QTL) affecting the risk of clinical mastitis (CM) and QTL affecting somatic cell score (SCS) exhibit pathogen-specific effects on the incidence of mastitis. Bacteriological data on mastitis pathogens were used to investigate...... pathogen specificity of QTL affecting treatments of mastitis in first parity (CM1), second parity (CM2), and third parity (CM3), and QTL affecting SCS. The 5 most common mastitis pathogens in the Danish dairy population were analyzed: Streptococcus dysgalactiae, Escherichia coli, coagulase...... against coagulase-negative staphylococci and Strep. uberis. Our results show that particular mastitis QTL are highly likely to exhibit pathogen-specificity. However, the results should be interpreted carefully because the results are sensitive to the sampling method and method of analysis. Field data were...

    Several multiple-media culture systems have become commercially available for on-farm identification of mastitis-associated pathogens. However, the accuracy of these systems has not been thoroughly and independently validated against microbiological evaluations performed by referral laboratories. Therefore, the purpose of the present study was to evaluate the performance of commercially available culture plates (Accumast, Minnesota Easy System, SSGN and SSGNC Quad plates) to identify pathogens associated with clinical mastitis in dairy cows. Milk samples from the affected quarter with clinical mastitis were aerobically cultured with the on-farm culture systems and by two additional reference laboratories. Agreeing results from both standard laboratories were denoted as the reference standard (RS). Accuracy (Ac), sensitivity (Se), specificity (Sp), positive and negative predictive values (PPV and NPV, respectively) and Cohen's kappa coefficient (k) of on-farm plates were determined based on the RS culture of 211 milk samples. All four plate-systems correctly identified ≥ 84.9% of milk samples with no bacterial growth. Accumast had greater values for all overall predictive factors (Ac, Se, Sp, PPV and NPV) and a substantial agreement (k = 0.79) with RS. The inter-rater agreements of Minnesota, SSGN, and SSGNC with RS were moderate (0.45 ≤ k ≤ 0.55). The effectiveness to categorize bacterial colonies at the genus and species was numerically different amongst the commercial plates. Our findings suggest that Accumast was the most accurate on-farm culture system for identification of mastitis-associated pathogens of the four systems included in the analysis.

    Majewski osteodysplastic primordial dwarfism type II (MOPD II) is an unusual autosomal recessive inherited form of primordial dwarfism, which is characterized by a small head diameter at birth, but which also progresses to severe microcephaly, progressive bony dysplasia, and characteristic facies and personality. This report presents a case of a five-year-old girl with MOPD II syndrome. The patient was referred to our clinic with the complaint of severe tooth pain at the left mandibular primary molar teeth. Clinical examination revealed that most of the primary teeth had been decayed and all primary teeth were hypoplastic. Patient's history revealed delayed development in the primary dentition and radiographic examination showed rootless primary molar teeth and short-rooted incisors. The treatment was not possible due to the lack of root of the left mandibular primary molars; so the teeth were extracted. Thorough and timely dental evaluation is crucial for the prevention of dental problems and the maintenance of oral health in patients with MOPD II syndrome is of utmost importance.

    Substance abuse treatment clients often present other severe mental health problems that affect treatment outcomes. Hence, screening and assessment for psychological distress and personality disorder are an important part of effective treatment, discharge, and aftercare planning. The Millon Clinical Multiaxial Inventory-II (MCMI-II) frequently is used for this purpose. In this paper, several issues of concern to MCMI-II users are addressed. These include the extent to which MCMI-II scales correspond to DSM-III-R disorders; overdiagnosis of disorders using the MCMI-II; accuracy of MCMI-II diagnostic cut-off scores; and the clinical utility of MCMI-II diagnostic algorithms. Approaches to addressing these issues are offered.

    Large animals have a relatively high seizure threshold, and in most cases seizures are acquired. No published case series have described this syndrome in cattle. To describe clinical findings and outcomes in cattle referred to the Veterinary Teaching Hospital of the University of Turin (Italy) because of seizures. Client-owned cattle with documented evidence of seizures. Medical records of cattle with episodes of seizures reported between January 2002 and February 2014 were reviewed. Evidence of seizures was identified based on the evaluation of seizure episodes by the referring veterinarian or 1 of the authors. Animals were recruited if physical and neurologic examinations were performed and if diagnostic laboratory test results were available. Forty-three of 49 cases fulfilled the inclusion criteria. The mean age was 8 months. Thirty-one animals were male and 12 were female. Piedmontese breed accounted for 39/43 (91%) animals. Seizures were etiologically classified as reactive in 30 patients (70%) and secondary or structural in 13 (30%). Thirty-six animals survived, 2 died naturally, and 5 were euthanized for reasons of animal welfare. The definitive cause of reactive seizures was diagnosed as hypomagnesemia (n = 2), hypocalcemia (n = 12), and hypomagnesemia-hypocalcemia (n = 16). The cause of structural seizures was diagnosed as cerebrocortical necrosis (n = 8), inflammatory diseases (n = 4), and lead (Pb) intoxication (n = 1). The study results indicate that seizures largely are reported in beef cattle and that the cause can be identified and successfully treated in most cases. Copyright © 2015 The Authors.

MethodsA total of 25 HRS-II patients admitted to our hospital from November 2011 to June 2014 were recruited into the treatment group, and 28 HRS-II patients treated with dopamine before 2011 were recruited into the control group. Patients in the treatment group were randomly divided into two subgroups: one subgroup (n=12 was given terlipressin once every 8 h, and the other subgroup (n=13 was given terlipressin once every 12 h. Both groups received albumin (Alb infusion to expand the blood volume before treatment with terlipressin or dopamine, and the course of treatment was 7 days. The improvement in clinical symptoms, levels of blood urea nitrogen (BUN, serum creatinine and electrolytes, urine volume, changes in liver function, and ascites disappearance in the two groups before and after treatment were compared. Comparison of categorical data between the two groups was made by χ2 test, and comparison of continuous data was made by t test. ResultsPatients in the control group showed no obvious symptom relief, but those in the treatment group had varying degrees of improvement in clinical symptoms. Neither group had significant changes in liver function and serum sodium level after treatment. The treatment group had significantly more patients whose ascites volume had decreased from large to medium than the control group (χ2=5.705, P<0.05.

  8. Failsafe automation of Phase II clinical trial interim monitoring for stopping rules.

    2010-02-01

    In Phase II clinical trials in cancer, preventing the treatment of patients on a study when current data demonstrate that the treatment is insufficiently active or too toxic has obvious benefits, both in protecting patients and in reducing sponsor costs. Considerable efforts have gone into experimental designs for Phase II clinical trials with flexible sample size, usually implemented by early stopping rules. The intended benefits will not ensue, however, if the design is not followed. Despite the best intentions, failures can occur for many reasons. The main goal is to develop an automated system for interim monitoring, as a backup system supplementing the protocol team, to ensure that patients are protected. A secondary goal is to stimulate timely recording of patient assessments. We developed key concepts and performance needs, then designed, implemented, and deployed a software solution embedded in the clinical trials database system. The system has been in place since October 2007. One clinical trial tripped the automated monitor, resulting in e-mails that initiated statistician/investigator review in timely fashion. Several essential contributing activities still require human intervention, institutional policy decisions, and institutional commitment of resources. We believe that implementing the concepts presented here will provide greater assurance that interim monitoring plans are followed and that patients are protected from inadequate response or excessive toxicity. This approach may also facilitate wider acceptance and quicker implementation of new interim monitoring algorithms.

    In a naturalistic clinical study of patients in the early stages of bipolar disorders the aim was to assess differences between patients with bipolar I (BD I) and bipolar II (BD II) disorders on clinical characteristics including affective symptoms, subjective cognitive complaints, functional level, the presence of comorbid personality disorders and coping strategies. Diagnoses were confirmed using the Structured Clinical Interview for DSM-IV Disorders. Clinical symptoms were rated with the Young Mania Rating Scale and the Hamilton Depression Rating Scale, and functional status using the Functional Assessment Short Test. Cognitive complaints were assessed using the Massachusetts General Hospital Cognitive and Physical Functioning Questionnaire, the presence of comorbid personality disorders using the Standardized Assessment of Personality - Abbreviated Scale and coping style using the Coping Inventory for Stressful Situations. In total, 344 patients were included (BD I (n=163) and BD II (n=181). Patients with BD II presented with significantly more depressive symptoms, more cognitive complaints, lower overall functioning, and a higher prevalence of comorbid personality disorders. Finally, they exhibited a trend towards using less adaptive coping styles. It cannot be omitted that some patients may have progressed from BD II to BD I. Most measures were based on patient self report. Overall, BD II was associated with a higher disease burden. Clinically, it is important to differentiate BD II from BD I and research wise, there is a need for tailoring and testing specific interventions towards BD II. Copyright © 2016 Elsevier B.V.

    To evaluate/assess the quality of the Clinical Practice Guidelines (CPGs) of traditional medicine in China. We systematically searched the literature databases WanFang Data, VIP, CNKI and CBM for studies published between 1978 and 2012 to identify and select CPGs of traditional medicine. We used the Appraisal of Guidelines for Research and Evaluation II (AGREE II) instrument to evaluate these guidelines. A total of 75 guidelines were included, of which 46 guidelines (62%) were on Traditional Chinese Medicine, 19 (25%) on Chinese Integrated Medicine, and 10 (13%) on Uyghur Medicine. Most traditional medicine CPGs published in domestic journals scored medicine. In each domain of AGREE II, traditional Medicine CPGs performed clearly better than international CPGs. The same trend was seen in guidelines of Modern Medicine. An increasing amount of CPGs are being published, but their quality is low. Referring to the key points of international guidelines development, supervision through AGREE II, cooperating with international groups and exploring the strategy of guideline development could improve the quality of CPGs on traditional medicine.

    The purpose of this study is to report the clinical results after repair of flexor tendon zone II injuries utilizing a 6-strand double-loop technique and early post-operative active rehabilitation. We retrospectively reviewed 22 patients involving 51 cases with zone II flexor tendon repair using a six strand double loop technique from September 1996 to December 2012. Most common mechanism of injuries was sharp lacerations (86.5 %). Tendon injuries occurred equally in manual and non-manual workers and were work-related in 33 % of the cases. The Strickland score for active range of motion (ROM) postoperatively was excellent and good in the majority of the cases (81 %). The rupture rate was 1.9 %. The six strand double loop technique for Zone II flexor tendon repair leads to good and excellent motion in the majority of patients and low re- rupture rate. It is clinically effective and allows for early postoperative active rehabilitation.

    The stronger the ceramic material, the longer the restoration stays in the mouth. The current study evaluated the two-year clinical performance of a strong ceramic system, IPS Empress II, with increased strength on onlay/inlay restorations of molars. Teeth from 35 patients, including three premolars and 32 molars, were prepared for 28 onlay and seven inlay restorations with IPS Empress II ceramics. The restorations were cemented with a highly viscous, dual-curing luting composite cement (Bifix) and evaluated by two examiners using USPHS criteria at baseline (one week following insertion), six months, one year and two years. The baseline scores and recalls were assessed by Wilcoxon signed rank test. Statistically significant marginal discoloration at the Bravo level was found at the 12- and 24-month recalls (p=0.046). One debonding was statistically insignificant. No changes were observed with respect to anamnesis, such as any symptom from the TMJ or masticatory muscles. No restorations were replaced due to hypersensitivity or were missing at the two-year evaluation. Any wear on the restoration, antagonist tooth or any changes of proximal contacts were not observed. IPS Empress II Ceramics were found to be appropriate as onlay/inlay restorations for clinical use under the conditions of the current study.

    2012-02-01

    Test-day (TD) records of milk, fat-to-protein ratio (F:P) and somatic cell score (SCS) of first-lactation Canadian Holstein cows were analysed by a three-trait finite mixture random regression model, with the purpose of revealing hidden structures in the data owing to putative, sub-clinical mastitis. Different distributions of the data were allowed in 30 intervals of days in milk (DIM), covering the lactation from 5 to 305 days. Bayesian analysis with Gibbs sampling was used for model inferences. Estimated proportion of TD records originated from cows infected with mastitis was 0.66 in DIM from 5 to 15 and averaged 0.2 in the remaining part of lactation. Data from healthy and mastitic cows exhibited markedly different distributions, with respect to both average value and the variance, across all parts of lactation. Heterogeneity of distributions for infected cows was also apparent in different DIM intervals. Cows with mastitis were characterized by smaller milk yield (down to -5 kg) and larger F:P (up to 0.13) and SCS (up to 1.3) compared with healthy contemporaries. Differences in averages between healthy and infected cows for F:P were the most profound at the beginning of lactation, when a dairy cow suffers the strongest energy deficit and is therefore more prone to mammary infection. Residual variances for data from infected cows were substantially larger than for the other mixture components. Fat-to-protein ratio had a significant genetic component, with estimates of heritability that were larger or comparable with milk yield, and was not strongly correlated with milk and SCS on both genetic and environmental scales. Daily milk, F:P and SCS are easily available from milk-recording data for most breeding schemes in dairy cattle. Fat-to-protein ratio can potentially be a valuable addition to SCS and milk yield as an indicator trait for selection against mastitis. © 2011 Blackwell Verlag GmbH.

    Full Text Available Osteopetrosis is a rare inherited genetic disease characterized by sclerosis of the skeleton caused by the absence or malfunction of osteoclasts. Three distinct forms of the disease have been recognized, autosomal dominant osteopetrosis being the most common. Autosomal dominant osteopetrosis exhibits a heterogeneous trait with milder symptoms, often at later childhood or adulthood. The aim of this case report is to present the clinical and radiographic features of a 35-year-old female patient with autosomal dominant osteopetrosis type II who exhibited features of chronic generalised periodontitis, and the radiographs revealed generalised osteosclerosis and hallmark radiographic features of ADO type II, that is, “bone-within-bone appearance” and “Erlenmeyer-flask deformity.”

    Full Text Available Infectious Bovine Rhinotracheitis is a disease of cattle characterised by clinical signs of the upper respiratory tract, reproductive tract and nervous system. A study to define the pathogenicity of four BHV-1 local isolates has been conducted. Fourteen Bali cattle that were free of BHV-1 has been selected and divided into four treatment groups. Each group of three was infected with virus isolate I, II, III and IV respectively with approximately a dose of 108TCID50 /10 ml and two cattle were used as control animals. Isolate I and III were originated from semen from IBR positive bulls number G 867 and G 148 respectively whereas isolate II was collected from vaginal mucosa and isolate IV was from nasal mucosa of IBR positive cattle treated with dexamethasone. Clinical response, gross-pathological and histopathological changes were observed. Immunohistochemical staining was applied to detect the antigen in tissue section. The results show that the BHV-1 local isolates could produce IBR syndrome namely fever and changes in the respiratory and reproductive tracts even though the clinical responses seemed to be disappeared by 21 days PI. Grossly there were hyperaemic nasal and vaginal mucosa and pneumonia whereas histologically there were non suppurative rhinitis, tracheitis, pneumonia and vulvovaginitis. Immunohistochemically the antigen was detected in the nasal concha and trachea. Dexamethasone treatment at 60-64 days PI could produce less severe clinical features and the second necroppsy at 69 days PI also results in less severe pathological responses. The findings also suggest that the pathogenicity of BHV-1 local isolates were as follows: isolates I, II, IV and III.

    Fore and hind limbs of 4-month-old Holstein-Friesian cattle ♀ (No.I) and those of 1-month-old Holstein-Friesian×Japanese Black cattle ♀ (No.II) suffering from syndactyly were dissected by means of radiographic examinations. The details were reported as follows. 1. The phalanges of both fore and left hind limbs of No.II cattle were completely fused. But, all the phalanges of left fore limb and proximal phalanges of right fore limb in No.I and the distal phalanges of right hind limb in No.II were normal, the others being of partial synostosis. 2. The distal parforating canal was absent in the metacarpus and the right metatarsus in No.II cattle. Also, in No.II on the distal part of the metacarpal or metatarsal, bone vestiges were noted, not only of the fifth and second metacarpus or metatarsus, but also the mutually jointed phalanges. 3. In No.I cattle, the left fore limb and 4 proximal sesamoid bones and 2 distal sesamoid bones, but the right limb had 4 sesamoid bones and 0 distal one. In No.II cattle, the fore limbs had 2 proximal and 0 distal sesamoid bones, left hind limb had 3 proximal and 0 distal ones, right hind limb had 3 proximal and 1 distal ones. 4. The arteries accommodated the syndactylous deformities. The median and radial arteries were fixed to be descended on to the palmar side of the metacarpus and mutually anastomosed to form a deep palmar arch. arising from the deep palmar arch, two branches (palmar proper digital aa. III and IV) were terminated by the lateral and medial palmar surfaces of the digit, where some anastomosing arches were formed by them. The arteries of the hind limbs were also similar to those of the fore limbs. 5. In radiographic examinations of syndactyly (in No.II) after 7-month feeding, hoof and digital bones were noted to have been developed, but distal phalanges were destructed and left in suspicion of bad prognosis

    The goal of this study was to evaluate the continuity across the Section II personality disorders (PDs) and the proposed Section III model of PDs in the Diagnostic and Statistical Manual of Mental Disorders (5th ed. [DSM-5]; American Psychiatric Association, 2013a ). More specifically, we analyzed association between the DSM-5 Section III pathological trait facets and Section II PDs among 110 Dutch adults (M age = 35.8 years, range = 19-60 years) receiving mental health care. We administered the Structured Clinical Interview for DSM-IV Axis II Disorders to all participants. Participants also completed the self-report Personality Inventory for DSM-5 (PID-5) as a measure of pathological trait facets. The distributions underlying the dependent variable were modeled as criterion counts, using negative binomial regression. The results provided some support for the validity of the PID-5 and the DSM-5 Section III Alternative Model, although analyses did not show a perfect match. Both at the trait level and the domain level, analyses showed mixed evidence of significant relationships between the PID-5 trait facets and domains with the traditional DSM-IV PDs.

    In the present field study the skin of the feet of 37 heavy draught horses of different breeds showing verrucous pastern dermatitis was examined clinically. Included were the degree of severity of the disease and the prevalence of anatomically normal structures associated with the skin: fetlock tufts of hair ("feathering"), ergots, chestnuts, bulges in the pastern region, cannon circumference. Each horse was examined for Chorioptes sp. skin mites. Information was also collected on the development of the skin alterations and housing conditions and feeding. These individual data were correlated with the clinical degree of severity of verrucous pastern dermatitis, which was evaluated using a numerical code (scoring system). In addition, punch biopsies were taken from the diseased skin of the feet and from healthy skin of the neck for comparative patho-histological examination (see Part III). Verrucous pastern dermatitis is a chronic disease which can be divided into four groups: scaling (group I), hyperkeratotic and hyperplastic plaque-like lesions (group II), tuberous skin masses (group III), and verrucous skin lesions with rugged surfaces (group IV). No correlation was found between the clinical degree of severity of the skin lesions and sex, breed, amount of work, use of stallions for breeding, grooming condition of the hair, white markings in the foot region, or Chorioptes sp. infestation. In regard to feeding it was found that the amount of maize and oats fed had some influence on the clinical degree of severity. Statistical analysis revealed a significant correlation between the clinical degree of severity and the age, the grooming condition of the hooves, and the mean cannon circumference. The prevalence of fetlock tufts of hair, chestnuts, ergots, and anatomically normal bulges in the pastern region also increased significantly with the clinical degree of severity. Furthermore the study revealed that the clinical degree of severity depended on the hygienic

    The aim of our study was to share our clinical experience on cases with patent ductus arteriosus treated with the Amplatzer Duct Occluder II. Between 2008 and 2012, 26 of 31 patients with patent ductus arteriosus underwent successful transcatheter closure of patent ductus arteriosus using the Amplatzer Duct Occluder II. Mean age was 3.3 years and mean weight was 15.7 kilograms. The presence of a residual shunt, left pulmonary artery or aortic obstruction was explored by administering contrast material during the procedure. The patients were discharged 24 hours after the procedure. The procedure was successful in 26 of 31 patients and failed in five patients. According to the Krichenko classification, 26 patients had type A, one patient had type B and 4 patients had type C ductus. The mean narrowest ductus diameter was 3.2 mm and the mean ductus length was 6.7 mm. Complete angiographic occlusion occurred immediately after the procedure in 22 out of 26 patients in whom the ductus was closed successfully with the Amplatzer Duct Occluder II. Complete occlusion was achieved in the remaining patients with residual shunt one month after the procedure. The procedure was preceded by closure with an Amplatzer Duct Occluder I in two patients and an Amplatzer Vascular Plug I in one patient. Amplatzer Duct Occluder II is highly effective in transcatheter closure of patent ductus arteriosus. We think that an alternative closure device and alternative techniques can be attempted in patients with type C ductus. The success rate could increase with accumulating experience.

    Angelica dahurica is a well-known traditional Chinese Medicine (TCM), while little information is available about its effects on pressure sores. We aimed to investigate the clinical effect of Angelica dahurica on patients with I-II phase pressure sores, as well as the underlying mechanism. Patients (n = 98) with phase I and phase II pressure sores were enrolled and randomly assigned to control and treated groups. In addition to holistic nursing, patients in the control group received compound clotrimazole cream, while patients in the treated group received continuous 4 weeks of external application of Angelica dahurica dressing. Therapeutic effect was recorded, along with the levels of interleukin-8 (IL-8), epidermal growth factor (EGF), transforming growth factor (TGF)-β, and vascular endothelial growth factor (VEGF). Besides, HaCaT cells were cultured with different concentrations of Angelica dahurica, and then cell viability, clone formation numbers, cell cycle, and levels of cyclin D1 and cyclin-dependent kinase (CDK) 2 were determined. The total effective rate in the treated group was significantly higher than in the control group. Levels of IL-8, EGF, TGF-β, and VEGF were statistically increased by Angelica dahurica. In addition, the cell viability and clone formation numbers were significantly upregulated by Angelica dahurica in a dose-dependent manner. Also, the percentage of cells in G0/G1 phase, and levels of cyclin D1 and CDK2 were significantly elevated. Our results suggest that Angelica dahurica may provide an effective clinical treatment for I-II phase pressure sores.

    As the incidence of invasive breast cancer will increase with age, the number of elderly patients with a diagnosis metastatic breast cancer will also rise. But the use of cytotoxic drugs in elderly metastatic breast cancer patients is not systematic and is dreaded by medical oncologists. The need for prospective oncologic data from this population seems increasingly obvious. The main objective of this review is to investigate design and characteristics of phase II trials that assess activity and feasibility of chemotherapies in elderly advanced/metastatic breast cancer patients. An electronic search in PUBMED allowed us to retrieve articles published in English language on phase II trials in elderly metastatic breast cancer between January 2002 and May 2016. Sixteen publications were finally included in this review. The primary endpoint was a simple, a composite, and a co-primary endpoints in 11, three, and two studies, respectively. Efficacy was the primary objective in 15 studies: simple (n = 10), composite (n = 3), co-primary endpoints (n = 2). Composite or co-primary endpoints combined efficacy and toxicity. Thirteen studies used multistage designs. Only five studies evaluated the feasibility, i.e., to jointly assess efficacy and tolerance to treatment (toxicity, quality of life, etc) as primary endpoint. Development of elderly specific phase III clinical trials might be challenging, it therefore seems essential to conduct phase II clinical trials evaluating jointly efficacy and toxicity in a well-defined geriatric population. Use of multistage designs that take into account heterogeneity would allow to identify a subpopulation at interim analysis and to reduce the number of patients exposed to an inefficient or a toxic treatment regimen. It is crucial to evaluate new therapies (targeted therapies, immunotherapies) using adequate methodologies (Study design, endpoint).

    To compare oral voriconazole with placebo in addition to topical antifungals in the treatment of filamentous fungal keratitis. The Mycotic Ulcer Treatment Trial II (MUTT II), a multicenter, double-masked, placebo-controlled, randomized clinical trial, was conducted in India and Nepal, with 2133 individuals screened for inclusion. Patients with smear-positive filamentous fungal ulcers and visual acuity of 20/400 (logMAR 1.3) or worse were randomized to receive oral voriconazole vs oral placebo; all participants received topical antifungal eyedrops. The study was conducted from May 24, 2010, to November 23, 2015. All trial end points were analyzed on an intent-to-treat basis. Study participants were randomized to receive oral voriconazole vs oral placebo; a voriconazole loading dose of 400 mg was administered twice daily for 24 hours, followed by a maintenance dose of 200 mg twice daily for 20 days, with dosing altered to weight based during the trial. All participants received topical voriconazole, 1%, and natamycin, 5%. The primary outcome of the trial was rate of corneal perforation or the need for therapeutic penetrating keratoplasty (TPK) within 3 months. Secondary outcomes included microbiologic cure at 6 days, rate of re-epithelialization, best-corrected visual acuity and infiltrate and/or scar size at 3 weeks and 3 months, and complication rates associated with voriconazole use. A total of 2133 patients in India and Nepal with smear-positive ulcers were screened; of the 787 who were eligible, 240 (30.5%) were enrolled. Of the 119 patients (49.6%) in the oral voriconazole treatment group, 65 were male (54.6%), and the median age was 54 years (interquartile range, 42-62 years). Overall, no difference in the rate of corneal perforation or the need for TPK was determined for oral voriconazole vs placebo (hazard ratio, 0.82; 95% CI, 0.57-1.18; P = .29). In prespecified subgroup analyses comparing treatment effects among organism subgroups, there was some

    In a field study of 80 cows in 9 dairy herds, serial liver biopsies were performed over the peripartum period to determine degree of hepatic lipidosis. Cattle were separated into categories of mild, moderate, and severe hepatic lipidosis on the basis of maximal amounts of hepatic triglyceride that accumulated during this period. Number of cattle with mild, moderate, and severe hepatic lipidosis were 52, 16, and 12, respectively. Cattle with severe hepatic lipidosis had greater concentrations of hepatic triglyceride before calving and after parturition, and greater serum nonesterified fatty acid concentrations and body condition loss after parturition than cattle with mild hepatic lipidosis. Rate of disease and culling and death rate because of disease were greater in cattle with severe hepatic lipidosis. Cattle with severe hepatic lipidosis had reproductive performance equal to clinically normal cattle; however, cattle with moderate hepatic lipidosis had increased days to conception, possibly related to greater milk production.

    The predictive value of the SYNTAX score (SS) for clinical outcomes after transcatheter aortic valve implantation (TAVI) is very limited and could potentially be improved by the combination of anatomic and clinical variables, the SS-II. We aimed to evaluate the value of the SS-II in predicting outcomes in patients undergoing TAVI. A total of 402 patients with severe symptomatic aortic stenosis undergoing transfemoral TAVI were included. Preprocedural TAVI angiograms were reviewed and the SS-I and SS-II were calculated using the SS algorithms. Patients were stratified in 3 groups according to SS-II tertiles. The coprimary endpoints were all-cause death and major adverse cardiovascular events (MACE), a composite of all-cause death, cerebrovascular event, or myocardial infarction at 1 year. Increased SS-II was associated with higher 30-day mortality (P=.036) and major bleeding (P=.015). The 1-year risk of death and MACE was higher among patients in the 3rd SS-II tertile (HR, 2.60; P=.002 and HR, 2.66; P<.001) and was similar among patients in the 2nd tertile (HR, 1.27; P=.507 and HR, 1.05; P=.895) compared with patients in the 1st tertile. The highest SS-II tertile was an independent predictor of long-term mortality (P=.046) and MACE (P=.001). The SS-II seems more suited to predict clinical outcomes in patients undergoing TAVI than the SS-I. Increased SS-II was associated with poorer clinical outcomes at 1 and 4 years post-TAVI, independently of the presence of coronary artery disease. Copyright © 2017 Sociedad Española de Cardiología.

    Experimental nitrogen dioxide inhalation has been reported to produce signs and lesions typical of field cases of bovine pulmonary adenomatosis (BPA) as described by Monlux et al, and Seaton. Similar lesions have been produced in mice and guinea pigs. These studies were conducted because of the similarities between silo-filler's disease of man, caused by nitrogen dioxide, and BPA. Since previous studies involved inadequate numbers of cattle, a more critical evaluation of the effects of nitrogen dioxide was needed. This project was designed to study the clinical and pathologic alterations induced in cattle by repeated exposure to nitrogen dioxide gas.

    Infection with hepatitis E virus (HEV) is the commonest cause of acute hepatitis worldwide. This infection, with fecal-oral transmission, was previously thought to be limited to humans residing in developing countries with poor sanitation, spreading via contaminated drinking water. In recent years, our understanding of epidemiology and clinical spectrum of this infection have changed markedly. This article reviews the epidemiology, including routes of transmission, and clinical manifestations of HEV infection around the world. In addition, recent findings on transmission-associated HEV infection, extrahepatic manifestations of hepatitis E and chronic infection with HEV, and treatment and prevention of this infection are discussed. Expert commentary: HEV infection has two distinct epidemiologic forms and clinical patterns of disease: (i) acute epidemic or sporadic hepatitis caused by fecal-oral (usually water-borne) transmission of genotype 1 and 2 HEV from a human reservoir in areas with poor hygiene and frequent water contamination, and (ii) infrequent sporadic hepatitis E caused by zoonotic infection, possibly from an animal source through ingestion of undercooked animal meal, of genotype 3 or 4 virus. In disease-endemic areas, pregnant women are at a particular risk of serious disease and high mortality. In less-endemic areas, chronic infection with HEV among immunosuppressed persons is observed. HEV can also be transmitted through Transfusion of blood and blood products. Ribivirin treatment is effective in chronic hepatitis E. Two efficacious vaccines have been tried in humans; one of these has received marketing approval in its country of origin.

    The present study aimed to investigate the molecular pathology of Waardenburg syndrome type II in three families, in order to provide genetic diagnosis and hereditary counseling for family members. Relevant clinical examinations were conducted on the probands of the three pedigrees. Peripheral blood samples of the probands and related family members were collected and genomic DNA was extracted. The coding sequences of paired box 3 (PAX3), microphthalmia‑associated transcription factor (MITF), sex‑determining region Y‑box 10 (SOX10) and snail family zinc finger 2 (SNAI2) were analyzed by polymerase chain reaction and DNA sequencing. The heterozygous mutation, c.649_651delAGA in exon 7 of the MITF gene was detected in the proband and all patients of pedigree 1; however, no pathological mutation of the relevant genes (MITF, SNAI2, SOX10 or PAX3) was detected in pedigrees 2 and 3. The heterozygous mutation c.649_651delAGA in exon 7 of the MITF gene is therefore considered the disease‑causing mutation in pedigree 1. However, there are novel disease‑causing genes in Waardenburg syndrome type II, which require further research.

    Full Text Available Introduction. Sagittal mandible deficiency is the most common cause of skeletal Class II malocclusion. Treatment objective is to stimulate sagittal mandible growth. Fixed functional Herbst appliance use is beneficial for shortening the time required for treatment and does not depend on patient compliance. Case outline. A 13-year-old girl was referred to the Clinic of Orthodontics, School of Dentistry in Belgrade following previous unsuccessful treatment of her skeletal Class II malocclusion using an activator. The patient's poor cooperation had led to failure of the treatment. Patient was subjected to the Herbst treatment for 6 months followed by fixed appliance for another 8 months. Lateral cephalograms before and after the treatment was performed. The remodelation of condylar and fossal articulation was assessed by superimposition of pre- and post-treatment temporomandibular joint tomograms. The promotion of oral hygiene and fluoride use was performed because orthodontic treatment carries a high caries risk and risk for periodontal disease. Skeletal and dental changes were observed after treatment (correction [Max+Mand]: molar relation 7 mm, overjet 8 mm, skeletal relation 5 mm, molars 2 mm, incisors 3 mm. Combination of Herbst and fixed appliances was effective in the treatment of dental and skeletal irregularities for a short period of time. Conclusion . In the retention period, 14 months after treatment, occlusal stability exists. Follow-up care in oral prevention is based on regular recalls at the dental office and supervision at home by the parents.

    Background China has the huge map and the largest population in the world. Previous studies on the prevalence and classification of headaches were conducted based on the general population, however, similar studies among the Chinese outpatient population are scarce. This study aimed to analyze the characteristics of 1843 headache patients enrolled in a North China headache clinic of the General Hospital for Chinese People's Liberation Army from October 2011 to May 2012, with the International Classification of Headache Disorders, 2nd Edition (ICHD-II). Methods and Results Personal interviews were carried out and a detailed questionnaire was used to collect medical records including age, sex and headache characteristics. Patients came from 28 regions of China with the median age of 40.9 (9–80) years and the female/male ratio of 1.67/1. The primary headaches (78.4%) were classified as the following: migraine (39.1%), tension-type headache (32.5%), trigeminal autonomic cephalalgias (5.3%) and other primary headache (1.5%). Among the rest patients, 12.9% were secondary headaches, 5.9% were cranial neuralgias and 2.5% were unspecified or not elsewhere classified. Fourteen point nine percent (275/1843) were given an additional diagnosis of chronic daily headache, including medication-overuse headache (MOH, 49.5%), chronic tension-type headache (CTTH, 32.7%) and chronic migraine (CM, 13.5%). The visual analogue scale (VAS) score of TTH with MOH was significantly higher than that of CTTH (6.8±2.0 vs 5.6±2.0, Pheadache clinic outpatients in a tertiary hospital of North China that migraine is the most common diagnosis. Furthermore, most headaches in this patient population can be classified using ICHD-II criteria. PMID:23239993

    To (1) evaluate rates of surgery for clinical stage I-II pancreatic ductal adenocarcinoma (PDAC), (2) identify predictors of not undergoing surgery, (3) quantify the degree to which patient- and hospital-level factors explain differences in hospital surgery rates, and (4) evaluate the association between adjusted hospital-specific surgery rates and overall survival (OS) of patients treated at different hospitals. Curative-intent surgery for potentially resectable PDAC is underutilized in the United States. Retrospective cohort study of patients ≤85 years with clinical stage I-II PDAC in the 2004 to 2014 National Cancer Database. Mixed effects multivariable models were used to characterize hospital-level variation across quintiles of hospital surgery rates. Multivariable Cox proportional hazards models were used to estimate the effect of adjusted hospital surgery rates on OS. Of 58,553 patients without contraindications or refusal of surgery, 63.8% underwent surgery, and the rate decreased from 2299/3528 (65.2%) in 2004 to 4412/7092 (62.2%) in 2014 (P < 0.001). Adjusted hospital rates of surgery varied 6-fold (11.4%-70.9%). Patients treated at hospitals with higher rates of surgery had better unadjusted OS (median OS 10.2, 13.3, 14.2, 16.5, and 18.4 months in quintiles 1-5, respectively, P < 0.001, log-rank). Treatment at hospitals in lower surgery rate quintiles 1-3 was independently associated with mortality [Hazard ratio (HR) 1.10 (1.01, 1.21), HR 1.08 (1.02, 1.15), and HR 1.09 (1.04, 1.14) for quintiles 1-3, respectively, compared with quintile 5] after adjusting for patient factors, hospital type, and hospital volume. Quality improvement efforts are needed to help hospitals with low rates of surgery ensure that their patients have access to appropriate surgery.

    Type II autosomal dominant osteopetrosis (ADO II, Albers-Schonberg disease) is a genetic condition characterized by generalized osteosclerosis predominating in some skeletal sites such as the spine and pelvis. ADO II is rare, and most available clinical descriptions are based on small numbers of patients. We report the clinical and radiological manifestations in 42 ADO II patients. To our knowledge, this is the largest series reported so far. Our inclusion criterion was presence on radiographs of the spine of vertebral endplate thickening, producing the classic sandwich vertebra appearance. We found various patterns of sandwich vertebra, of which we provide a description to assist physicians in diagnosing ADO II. The classic bone-within-bone appearance was present in most but not all skeletal sites. The radiological penetrance of the disease was high (90%) and increased after 20 years of age. As many as 81% of our patients experienced clinical manifestations. Fractures were common (78% of patients) and healed slowly. Hip osteoarthritis developed in 27% of patients and required arthroplasty in 9 of the 16 affected hips. Nonmandibular osteomyelitis occurred in 4 cases (11%). Twenty-four percent of patients had thoracic or lumbar scoliosis. Orthopedic surgery was performed in 52.8% of patients, of whom half had at least three surgical procedures for internal fracture fixation, arthroplasty, limb deformity correction, or treatment of surgical complications. There was a high rate of surgical complications including nonunion, infection, prosthesis loosening, and intraoperative fractures. Nearly two-thirds of patients (64%) had stomatologic manifestations, including mandibular osteomyelitis in 4 patients (11%). Cranial nerve involvement responsible for hearing loss, bilateral optic atrophy, and/or facial palsy was present in 14 patients but was clearly attributable to ADO II in only 6 cases (16%). This large series sheds new light on several aspects of ADO II, most

    Purpose: In September 1989, a postoperative Phase II high dose rate (HDR) brachytherapy protocol was started for International Federation of Gynecology and Obstetrics (FIGO) Stage I endometrial adenocarcinoma. This review reports the overall survival, local control, and complication rates for the initial 63 patients treated in this Phase II study. Methods and Materials: High dose rate brachytherapy was delivered using an Iridium-192 HDR remote afterloader. Sixty-three patients were entered into the Phase II protocol, each receiving two vaginal cuff treatments 1 week apart (range 4-12 days) with vaginal ovoids (diameter 2.0-3.0 cm). No patient received adjuvant external beam radiation. A dose of 32.4 Gy in two fractions was prescribed to the ovoid surface in 63 patients. The first three patients treated at our institution received 15, 16.2, and 29 Gy, respectively, to determine acute effects. Results: At a median follow-up of 1.6 years (range 0.75-4.3 years) no patient has developed a vaginal cuff recurrence. One regional recurrence (1.6%) occurred at 1.2 years at the pelvic side wall. This patient is alive and without evidence of disease 7 months after completion of salvage irradiation, which resulted in the only vaginal stenosis (1.6%). Fourteen patients (22%) experienced vaginal apex fibrosis by physical exam, which was clinically symptomatic in four patients. Two patients reported stress incontinence; however, these symptoms were noted prior to their HDR therapy. One patient died 2.4 years after HDR therapy due to cardiovascular disease without evidence of cancer at autopsy. Conclusion: Preliminary results of our phase II HDR vaginal cuff protocol for postoperative FIGO Stage IA, Grade 3 or Stage IB, Grade 1-2 patients demonstrate that 32.4 Gy in two fractions is well tolerated by the vaginal cuff mucosa. Local control appears comparable to our prior experience and others with low dose rate (LDR) brachytherapy. Additional patient accrual and further follow

    We compared the time to achieve remission and the clinical characteristics of patients with bipolar depressive mixed state and those with bipolar depressive non-mixed state. The subjects (N=131) were inpatients diagnosed between 2006 and 2012 with bipolar I or II disorder, depression and were classified into the following three groups: "pure depressive state" (PD, n=70), "sub-threshold mixed state" (SMX, n=38), and "depressive mixed state" (DMX, n=23). Diagnosis of a DMX was in accordance with Benazzi's definition: three or more manic symptoms in a depressive episode. The subjects' charts were retrospectively reviewed to ascertain the time to achieve remission from the index episode and to identify other factors, such as demographic and clinical characteristics, specific manic symptoms, and pharmacological treatment, that may have contributed to remission. The time to achieve remission was significantly longer in the DMX (p=0.022) and SMX (p=0.035) groups than in the PD group. Adjustment for covariates using a Cox proportional hazards model did not change these results. Clinically, subjects with a DMX were more likely to have manic symptoms in the index episode, especially inflated self-esteem and psychomotor agitation than those in the PD. We investigated only inpatients and therefore could not comment on outpatients. These findings showed that sub-syndromal manic symptoms in bipolar depression had different clinical characteristics and a more severe illness course, including a longer time to achieve remission, than did a pure depressive state. © 2013 Elsevier B.V.

    In part I of the paper the biomechanical and technical background of the EPTT using the MPT fixator and the indications for this procedure have been described. In part II we report about the clinical application of the EPTT in 67 patients with a wide spectrum of repairs and reconstructions of the extensor mechanism. 48 patients had fresh injuries, 18 of them with severe concomitant knee lesions and 19 patients had neglected rsp. unsuccessfully operated injuries. There were 4 deep infections, two of them related to the MPT fixator. In the patients with uneventful healing the fixator remained in place for 7.3 weeks in average. The clinical, isokinetic and radiological results were reviewed in 17 patients with an average follow-up time of 37.3 months. There were 5 patients with partial patellectomy and tendon reattachment because of lower patella pole comminution and 12 patients with tendon reattachment ruptured at the inferior patella pole or suture repair in midsubstance rupture. The clinical results according to the IKDC score were rated in 3 patients as normal, in 10 patients as nearly normal and in 4 patients as abnormal. This rating was highly dependend on the subjective judgement by the patients who considered their operated knees not as normal as the contralateral knees. From our clinical experiences and results we can derive that the EPTT enables the surgical management of extensor mechanism disruptions with a minimum of internal fixation material and provides a safe protection of the repairs and reconstructions during the healing period. The EPTT allows immediate unrestricted functional rehabilitation and early walking without crutches. Thus the EPTT represents an effective alternative to the patello-tibial cerclage with a wire or synthetic ligaments.

    Bipolar disorder (BD) is a chronic, frequently comorbid condition characterized by high rates of mood episode recurrence and suicidality. Little is known about prospective longitudinal characterization of BD type II (BD II) versus type I (BD I) in relation to time to depressive recurrence and recovery from major depressive episode. We therefore assessed times to depressive recurrence/recovery in tertiary clinic-referred BD II versus I patients. Outpatients referred to Stanford BD Clinic during 2000-2011 were assessed with Systematic Treatment Enhancement Program for BD (STEP-BD) Affective Disorders Evaluation and with Clinical Monitoring Form during up to 2 years of naturalistic treatment. Prevalence and clinical correlates of bipolar subtype in recovered (euthymic ≥8 weeks) and depressed patients were assessed. Kaplan-Meier analyses assessed the relationships between bipolar subtype and longitudinal depressive severity, and Cox proportional hazard analyses assessed the potential mediators. BD II versus BD I was less common among 105 recovered (39.0 vs. 61.0%, p = 0.03) and more common among 153 depressed (61.4 vs. 38.6%, p = 0.006) patients. Among recovered patients, BD II was associated with 6/25 (24.0%) baseline unfavorable illness characteristics/mood symptoms/psychotropics and hastened depressive recurrence (p = 0.015). Among depressed patients, BD II was associated with 8/25 (33.0%) baseline unfavorable illness characteristics/mood symptoms/psychotropics, but only non-significantly associated with delayed depressive recovery. BD II versus BD I was significantly associated with current depression and hastened depressive recurrence, but only non-significantly associated with delayed depressive recovery. Research on bipolar subtype relationships with depressive recurrence/recovery is warranted to enhance clinical management of BD patients.

  4. Divergences between clinical and research methods for assessing personality disorders: implications for research and the evolution of axis II.

    The purpose of this study was to examine the extent to which instruments for assessing axis II diverge from clinical diagnostic processes. Subjects in the first study were 52 clinicians with experience in assessment and treatment of patients with personality disorders, who were surveyed about the methods they use in clinical practice to make diagnoses and other aspects of the diagnostic process. A second study replicated the major findings with a random national sample of 1,901 experienced psychiatrists and psychologists. Whereas current instruments rely primarily on direct questions derived from DSM-IV, clinicians of every theoretical persuasion found direct questions useful for assessing axis I disorders but only marginally so for axis II. They made axis II diagnoses, instead, by listening to patients describe interpersonal interactions and observing their behavior with the interviewer. In contrast to findings with current research instruments, most patients with personality disorders in clinical practice receive only one axis II diagnosis, and if they receive more than one, one is considered primary. Clinicians reported treating a substantial number of patients for enduring personality patterns that current axis II instruments do not assess, many of which meet neither axis I nor axis II criteria, notably problems with relatedness, work, self-esteem, and chronic subclinical depressive traits. Measurements of axis II were constructed by using a model derived from axis I instruments that diverges from clinical diagnostic procedures in a way that may be problematic for the assessment of personality disorders and the development of a more clinically and empirically sound taxonomy.

    Chronic constipation (CC) is a common gastrointestinal (GI) motility disorder that significantly impairs the quality of life in affected subjects. As almost half of the patients suffering from CC are not satisfied with currently available medicines, there is a need to develop new molecules with better effectiveness and tolerability. The authors include all experimental and clinical trials (up to Phase II) about new investigational drugs for the treatment of CC. The article identifies nine new agents: mitemcinal, TD-8954, YKP10811, itopride, RM-131, KWA-0711, elobixibat, velusetrag, and naronapride. All nine agents have shown prokinetic effects in different stages of the development. The mechanisms of new developing drugs include: the activation of 5-hydroxytryptamine type-4 (5-HT4), ghrelin and motilin receptors, antagonizing dopamine type-2 (D2) receptors, inhibition of ileal bile acid reabsorption and acetylcholine esterase, as well as water absorption from the GI tract. At this current point in time, new generations of 5-HT4 receptor agonists (velusetrag, noranopride and YKP10811) are hoped to progress, further in the future, due to better efficiency and safety. However, it is not possible to make a concise conclusion at this current time due to a lack of evidence. Further clinical trials with a longer duration and a larger sample size are warranted.

    Colombia is developing multiple national practice guidelines from a range of diseases. Clinical practice guidelines represent a very useful tool to be able to take decision over a patient care that is widely available for the clinician. In psychiatry there are a good number of international clinical guidelines for the treatment of schizophrenia nevertheless there is no article that evaluate them scientifically In the settings of developing a Colombian schizophrenia practice guideline, a systematic search was performed in multiple databases and the results were then evaluated by two trained persons. We present the results globally and by domains. We found 164 matches for possible guidelines. After screening 7 guidelines were evaluated with the AGREE II instrument. Globally and by the different domains, the National Institute for Health and Care Excellence (NICE) was the guideline that got the best score. From the guidelines that were reviewed, 4 were from Europe and only 2 were from Latin America. None of the guidelines used GRADE methodology for the recommendations. The diversity of the schizophrenia treatment guidelines does not allow an easy adoption of the recommendation by a psychiatrist in Colombia. Copyright © 2014 Asociación Colombiana de Psiquiatría.

    Gait deficits are prevalent in people with dementia and increase their fall risk and future disability. Few treatments exist for gait impairment in Alzheimer's disease (AD) but preliminary studies have shown that cognitive enhancers may improve gait in this population. To determine the efficacy of donepezil, a cognitive enhancer that improves cholinergic activity, on gait in older adults newly diagnosed with AD. Phase II clinical trial in 43 seniors with mild AD who received donepezil. Participants had not previously received treatment with cognitive enhancers. Primary outcome variables were gait velocity (GV) and stride time variability (STV) under single and dual-task conditions measured using an electronic walkway. Secondary outcomes included attention and executive function. After four months of treatment, participants with mild AD improved their GV from 108.4 ± 18.6 to 113.3 ± 19.5 cm/s, p = 0.010; dual-task GV from 80.6 ± 23.0 to 85.3 ± 22.3 cm/s, p = 0.028. Changes in STV were in the expected direction although not statistically significant. Participants also showed improvements in Trail Making Tests A (p = 0.030), B (p = 0.001), and B-A (p = 0.042). Donepezil improved gait in participants with mild AD. The enhancement of dual-task gait suggests the positive changes achieved in executive function as a possible causal mechanism. This study yielded a clinically significant estimate of effect size; as well, the findings are relevant to the feasibility and ethics considerations for the design of a Phase III clinical trial.

    Purpose: To develop the methodology to evaluate the clinical performance of a Phase II Proton CT scanner Methods: Range errors on the order of 3%-5% constitute a major uncertainty in current charged particle treatment planning based on Hounsfield Unit (HU)-relative stopping power (RSP) calibration curves. Within our proton CT collaboration, we previously developed and built a Phase I proton CT scanner that provided a sensitive area of 9 cm (axial) × 18 cm (in-plane). This scanner served to get initial experience with this new treatment planning tool and to incorporate lessons learned into the next generation design. A Phase II scanner was recently completed and is now undergoing initial performance testing. It will increase the proton acquisition rate and provide a larger detection area of 9 cm x 36 cm. We are now designing a comprehensive evaluation program to test the image quality, imaging dose, and range uncertainty associated with this scanner. The testing will be performed along the lines of AAPM TG 66. Results: In our discussion of the evaluation protocol we identified the following priorities. The image quality of proton CT images, in particular spatial resolution and low-density contrast discrimination, will be evaluated with the Catphan600 phantom. Initial testing showed that the Catphan uniformity phantom did not provide sufficient uniformity; it was thus replaced by a cylindrical water phantom. The imaging dose will be tested with a Catphan dose module, and compared to a typical cone beam CT dose for comparable image quality. Lastly, we developed a dedicated dosimetry range phantom based on the CIRS pediatric head phantom HN715. Conclusion: A formal evaluation of proton CT as a new tool for proton treatment planning is an important task. The availability of the new Phase II proton CT scanner will allow us to perform this task.

    Full Text Available Background: The ultimate goal of periodontal therapy is predictable regeneration of a functional attachment apparatus destroyed as a result of periodontitis. Reconstructive procedures have been used with varying success during the past decades to accomplish this goal. Aim: To evaluate whether the use of porous hydroxyapatite alone or a bioresorbable membrane alone would enhance the clinical results in the treatment of class II furcation defects in human lower molars. Materials and Methods: Fifteen patients with chronic periodontitis, aged between 39 and 49 years, with a pair of similar bilateral class II furcation defects (classification of Hamp et al. in mandibular first molars were selected. A split-mouth design was incorporated and the selected 30 furcation defects were assigned to one of the two treatment groups, i.e., Group I treated with a bioresorbable membrane from bovine-derived collagen guided tissue regeneration membrane and Group II treated using porous hydroxyapatite bone graft material on the contralateral sides. Evaluation of clinical parameters, probing depths and attachment levels, and radiographs was done preoperatively and 6 months postoperatively. Results: Both the groups showed statistically significant mean reduction in probing depths and gain in clinical attachment levels and linear bone fill. Comparison between Group I and Group II showed insignificant difference. Conclusion: Within the limits of this study, both the treatment modalities are beneficial for the treatment of human mandibular class II furcation defects.

    Full Text Available China has the huge map and the largest population in the world. Previous studies on the prevalence and classification of headaches were conducted based on the general population, however, similar studies among the Chinese outpatient population are scarce. This study aimed to analyze the characteristics of 1843 headache patients enrolled in a North China headache clinic of the General Hospital for Chinese People's Liberation Army from October 2011 to May 2012, with the International Classification of Headache Disorders, 2nd Edition (ICHD-II.Personal interviews were carried out and a detailed questionnaire was used to collect medical records including age, sex and headache characteristics. Patients came from 28 regions of China with the median age of 40.9 (9-80 years and the female/male ratio of 1.67/1. The primary headaches (78.4% were classified as the following: migraine (39.1%, tension-type headache (32.5%, trigeminal autonomic cephalalgias (5.3% and other primary headache (1.5%. Among the rest patients, 12.9% were secondary headaches, 5.9% were cranial neuralgias and 2.5% were unspecified or not elsewhere classified. Fourteen point nine percent (275/1843 were given an additional diagnosis of chronic daily headache, including medication-overuse headache (MOH, 49.5%, chronic tension-type headache (CTTH, 32.7% and chronic migraine (CM, 13.5%. The visual analogue scale (VAS score of TTH with MOH was significantly higher than that of CTTH (6.8±2.0 vs 5.6±2.0, P<0.001. The similar result was also observed in VAS score between migraine with MOH and CM (8.0±1.5 vs 7.0±1.5, P = 0.004. The peak age at onset of TTH for male and female were both in the 3(rd decade of life. However, the age distribution at onset of migraine shows an obvious sex difference, i.e. the 2(nd decade for females and the 1(st decade for males.This study revealed the characteristics of the headache clinic outpatients in a tertiary hospital of North China that migraine is

    Full Text Available Cattle are the main reservoir host of C. andersoni, which shows a predominance in yearlings and adults of cattle. To understand the subtypes of C. andersoni and the population genetic structure in Heilongjiang Province, fecal specimens were collected from 420 dairy cattle and 405 beef cattle at the age of 12-14 months in eight cattle farms in five areas within this province and were screened for the presence of Cryptosporidium oocysts by microscopy after Sheather's sugar flotation technique. The average prevalence of Cryptosporidium spp. was 19.15% (158/825 and all the Cryptosporidium isolates were identified as C. andersoni by the SSU rRNA gene nested PCR-RFLP using SspI, VspI and MboII restriction enzymes. A total of 50 C. andersoni isolates were randomly selected and sequenced to confirm the RFLP results before they were subtyped by multilocus sequence typing (MLST at the four microsatellite/minisatellite loci (MS1, MS2, MS3 and MS16. Four, one, two and one haplotypes were obtained at the four loci, respectively. The MLST subtype A4,A4,A4,A1 showed an absolute predominance and a wide distribution among the six MLST subtypes obtained in the investigated areas. Linkage disequilibrium analysis showed the presence of a clonal population genetic structure of C. andersoni in cattle, suggesting the absence of recombination among lineages. The finding of a clonal population genetic structure indicated that the prevalence of C. andersoni in cattle in Heilongjiang Province is not attributed to the introduction of cattle. Thus, prevention and control strategies should be focused on making stricter measures to avoid the occurrence of cross-transmission and re-infection between cattle individuals. These molecular data will also be helpful to explore the source attribution of infection/contamination of C. andersoni and to elucidate its transmission dynamics in Heilongjiang Province, even in China.

    Background: Recurrent gynecologic cancers are often difficult to manage without significant morbidity. We conducted a phase II study to assess the safety and the efficacy of ablative robotic stereotactic body radiosurgery (SBRT) in women with metastatic gynecologic cancers. Methods: A total of 50 patients with recurrent gynecologic cancer who had single or multiple (≤4) metastases underwent robotic-armed Cyberknife SBRT (24Gy/3 daily doses). Toxicities were graded prospectively by common toxicity criteria for adverse events (version 4.0). SBRT target responses were recorded following RECIST criteria (version 1.0). Rates of clinical benefit for SBRT and non-radiosurgical disease relapse were calculated. Disease-free and overall survivals were estimated by the Kaplan–Meier method and the Cox proportional hazards model was used to control for prognostic variables. Findings: SBRT was safely delivered, with 49 (98%) of 50 patients completing three prescribed fractions. The most frequent grade 2 or higher adverse events attributed to SBRT included fatigue (16%), nausea (8%), and diarrhea (4%). One (2%) grade four hyperbilirubinemia occurred. SBRT target response was 96% (48 of 50 patients). A 6-month clinical benefit was recorded in 34 [68% (95% CI, 53.2, 80.1)] patients. No SBRT targeted disease progressed. Non-radiosurgical disease relapse occurred in 31 (62%) patients. Median disease-free survival was 7.8 months (95% CI, 4.0, 11.6). Median overall survival was 20.2 months (95% CI, 10.9, 29.5). Interpretation: SBRT safely controlled metastatic gynecologic cancer targets. Given an observed high rate of non-radiosurgical disease relapse, a phase I trial assessing co-administration of SBRT and cytotoxic chemotherapy is underway.

    In today's climate of cost containment and fiscal responsibility, generic implant alternatives represent an interesting area of untapped resources. As patents have expired on many commonly used trauma implants, generic alternatives have recently become available from a variety of sources. The purpose of this study was to examine the clinical and economic impact of a cost containment program using high quality, generic orthopaedic locking plates. The implants available for study were anatomically precontoured plates for the clavicle, proximal humerus, distal radius, proximal tibia, distal tibia, and distal fibula. Retrospective review. Level II Trauma center. 828 adult patients with operatively managed clavicle, proximal humerus, distal radius, proximal tibia, tibial pilon, and ankle fractures. Operative treatment with conventional or generic implants. The 414 patients treated with generic implants were compared with 414 patients treated with conventional implants. There were no significant differences in age, sex, presence of diabetes, smoking history or fracture type between the generic and conventional groups. No difference in operative time, estimated blood loss or intraoperative complication rate was observed. No increase in postoperative infection rate, hardware failure, hardware loosening, malunion, nonunion or need for hardware removal was noted. Overall, our hospital realized a 56% reduction in implant costs, an average savings of $1197 per case, and a total savings of $458,080 for the study period. Use of generic orthopaedic implants has been successful at our institution, providing equivalent clinical outcomes while significantly reducing implant expenditures. Based on our data, the use of generic implants has the potential to markedly reduce operative costs as long as quality products are used. Therapeutic Level III.

    The genetic diversity of Cryptosporidium spp. and Giardia duodenalis from dairy cattle and pigs in Denmark was determined in the present study. Faecal samples from 1237 pigs and 1150 cattle originating from 50 sow herds and 50 dairy herds, respectively, were analysed for the presence of the two...... parasites by immunofluorescence microscopy. A large proportion of the (oo)cyst containing samples were selected for molecular characterization. Sequencing and phylogenetic analysis of the 18S rDNA locus and/or the HSP70 gene of 183 pig and 154 cattle isolates of Cryptosporidium revealed the presence of C....... suis, pig genotype II, C. parvum (cattle genotype), C. bovis, Cryptosporidium deer-like genotype and a novel C. suis-like genotype. For both cattle and pigs, a host age-related change in distribution of species/genotypes was observed. The zoonotic C. parvum (cattle genotype) was most prevalent in young...

    There is now an abundance of anti-diabetic agents. However, only few patients achieve glycemic targets. Moreover, current glucose-lowering agents mainly depend upon insulin secretion or function. Sodium glucose co-transporter type 2 (SGLT2) inhibitors present a novel glucose-lowering therapy, inducing glycosuria in an insulin-independent fashion. In this review, the authors discuss the key efficacy and safety data from phase II clinical trials in type 2 diabetes mellitus (T2DM) of the main SGLT2 inhibitors approved or currently in development, and provide a rationale for their use in T2DM. Despite the very promising characteristics of this new therapeutic class, a number of issues await consideration. One important question is what to expect from head-to-head comparison data. We also need to know if dual inhibition of SGLT1/SGLT2 is more efficacious in reducing HbA1c and how this therapy affects metabolic and cardiovascular parameters. Additionally, several SGLT2 agents that have not yet come to market have hitherto been evaluated in Asian populations, whereas approved SGLT2 inhibitors have been frequently studied in other populations, including Caucasian subjects. Thus, we need more information on the potential role of ethnicity on their efficacy and safety.

    To investigate clinical value of glomerular filtration rate (GFR) and urine microalbumin in early diagnosis of diabetic nephropathy, GFR in 60 patients with type II diabetes mellitus and a control group of 20 were determined using 99 Tc m DTPA renal dynamic imaging and urine microalbumin. The following results were obtained.Among the 60 patients with diabetes, 5 patients had increased GFRs of, 142.0±13.6 mg/min, which was 35% higher than that of controls and differed significantly from the control (P<0.01); 20 patients had GFRs of 102.2±10.2 mg/min, which differed little from the control; and 35 patients had declined GFRs of 57.2±18.0 mg/min, which was 54.3% lowered than the control and differed significantly from the control (P<0.01). The urine microalbumin in diabetes patients was significantly higher than the control. In conclusion, the GFR is a good index of the early kidney injury in diabetic patients. The combined detection of GFR and urine microalbumin can improve the early diagnosis of diabetic nephropathy, and may help to monitor the treatment response and assess prognosis. (authors)

    A significant number of clinical practice guidelines (CPGs) about the treatment of acne vulgaris in adolescents and adults have been published worldwide. However, little is known about the quality of CPGs in this field. The aim of this study was to appraise the methodological quality of published acne vulgaris CPGs. We performed a systematic review of published CPGs on acne vulgaris therapy from July 2002 to July 2012. Three reviewers independently assessed each CPG using the AGREE II instrument. A standardized score was calculated for each of the six domains. Our search strategy identified 103 citations but just six met our inclusion criteria. Agreement among reviewers was very good: 0.981. The domains that scored better were: "scope and purpose" and "clarity and presentation". Those that scored worse were "stakeholder involvement", "rigor of development", and "applicability". The European and the Malaysian CPGs were the only recommended with no further modifications. In addition, the Mexican, Colombian and the United States guidelines were recommended with provisos, with lower scores regarding stakeholder involvement, rigor of development and applicability. Only two guidelines clearly reported outcome measures for evaluating efficacy or included quality of life outcomes. CPGs varied regarding the consideration of light/laser therapy or consideration of complementary/alternative medicines. None of them included cost considerations of drugs such as systemic isotretinoin. In conclusion, published acne vulgaris CPGs for acne therapy vary in quality with a clear need to improve their methodological rigor. This could be achieved with the adherence to current CPGs development standards.

    Purpose : To obtain the optical treatment method in patients with endometrial carcinoma(clinical stage FIGO I, II) by comparative analysis between preoperative radiotherapy(pre-op R) and postoperative radiotherapy(post-op RT). Materials and Methods : A retrospective review of 62 endometrial carcinoma patients referred to the Yonsei Cancer Center for radiotherapy between 1985 and 1991 was undertaken. Of 62 patients, 19 patients(Stage I; 12 patients, Stage II; 7 patients) received pre-op RT before TAH(Total Abdominal Hysterectomy) and BSO(Bilateral Salphingoophorectomy) (Group 1) and 43 patients( Stage 1; 32 patients, Stage 2; 11 patients) received post-op RT after TAH and BSO (Group 2). Pre-op irradiation was given 4-6 weeks prior to surgery and post-op RT was administered on 4-5 weeks following surgery. All patients exept 1 patient(Group2; ICR alone) received external irradiation. Seventy percent(13/19) of pre-op RT group and 54 percent(23/42) of post-op RT group received external pelvic irradiation and intracavitary radiation therapy(ICR). External radiation dose was 39.6-55Gy(median 45Gy) in 5-6 week through opposed AP/PA fields or 4-field box technique treating daily, five days per week, 180cGy per fraction. ICR doses were prescribed to point A(20-39.6 Gy, median 39Gy) in Group 1 and 0.5cm depth from vaginal surface (18-30 Gy, median 21Gy) in Group2. Results : The overall 5 year survival rate was 95%. No survival difference between pre-op and post-op RT group.(89.3% vs 97.7%, p>0.1) There was no survival difference by stage, grade and histology between two groups. The survival rate was not affected by presence of residual tumor of surgical specimen after pre-op RT in Group 1(p>0.1), but affected by presence of lymph node metastasis in post-op RT group(p<0.5). The complication rate of pre-op RT group was higher than post-op RT.(16% vs 5%) Conclusion : Post-op radiotherapy offers the advantages of accurate surgical-pathological staging and low complication rate

    Usher syndrome types I and II are clinical syndromes with substantial genetic and clinical heterogeneity. We undertook the current study in order to identify ocular symptoms and signs that could differentiate between the two types. Sixty-seven patients with Usher syndrome were evaluated. Based on audiologic and vestibular findings, patients were classified as either Usher type I or II. The severity of the ocular signs and symptoms present in each type were compared. Visual acuity, visual field area, electroretinographic amplitude, incidence of cataract and macular lesions were not significantly different between Usher types I and II. However, the ages when night blindness was perceived and retinitis pigmentosa was diagnosed differed significantly between the two types. There seems to be some overlap between types I and II of Usher syndrome in regard to the ophthalmologic findings. However, night blindness appears earlier in Usher type I (although the difference in age of appearance appears to be less dramatic than previously assumed). Molecular elucidation of Usher syndrome may serve as a key to understanding these differences and, perhaps, provide a better tool for use in clinical diagnosis, prognosis and genetic counseling.

    Full Text Available Abstract Background Much of the literature on panic disorder (PD-bipolar disorder (BP cormorbidity concerns BP-I. This literature emphasizes the difficulties encountered in pharmacologic treatment and outcome when such comorbidity is present. The present report explores these issues with respect to BP-II. Methods The sample comprised 326 outpatients (aged 34.5 ± 11.5 years old; 222 females with Diagnostic and Statistical Manual of Mental Disorders 3rd edn, revised (DSM-III-R PD-agoraphobia; among them 52 subjects (16% were affected by lifetime comorbidity with BP-II. Patients were evaluated by means of the Structured Clinical Interview for DSM-IV (SCID, the Panic-Agoraphobia Interview, and the Longitudinal Interview Follow-up Examination (Life-Up and treated according to routine clinical practice at the University of Pisa, Italy, for a period of 3 years. Clinical and course features were compared between subjects with and without BP-II. All patients received the clinicians' choice of antidepressants and, in the case of the subsample with BP-II, mood stabilizers (for example, valproate, lithium were among the mainstays of treatment. Results In comparison to patients without bipolar comorbidity, those with BP-II showed a significantly greater frequency of social phobia, obsessive-compulsive disorder, alcohol-related disorders, and separation anxiety during childhood and adolescence. Regarding family history, a significantly greater frequency of PD and mood disorders was present among the BP-II. No significant differences were observed in the long-term course of PD or agoraphobic symptoms under pharmacological treatment or the likelihood of spontaneous pharmacological treatment interruptions. Conclusion Although the severity and outcome of panic-agoraphobic symptomatology appear to be similar in patients with and without lifetime bipolar comorbidity, the higher number of concomitant disorders in our PD patients with BP-II does indicate a greater

    Sarcopenia affects more than 10% of older adults. Next to age-associated physiologic changes, diseases like diabetes or inflammatory, neurological, malignant and endocrine disorders may contribute to the development of sarcopenia. Likewise, polypharmacy, i.e., multiple drug use, is common among older adults. Although the two conditions frequently co-occur, the association of polypharmacy with sarcopenia has not yet been examined. We investigated the association of polypharmacy and sarcopenia in a large cohort of community-dwelling older adults (60-84 years). Thousand five hundred and two participants from the Berlin Aging Study II were included. Polypharmacy was defined as concurrent use of 5 or more drugs (prescription and nonprescription). Body composition was assessed with dual-energy X-ray absorptiometry, and appendicular lean mass (ALM) was calculated as sum of the four limbs' lean mass. Sarcopenia was defined as low ALM-to-body mass index (BMI)-ratio using validated sex-specific cutoffs. Mean age was 68.7 ± 3.7 years, 50.7% were female. The median (interquartile range) number of drugs was 2 (1-4); 21.1% of subjects reported regular use of ≥5 drugs. Subjects with polypharmacy were more often sarcopenic according to the applied ALM/BMI-cutoffs (16.3% vs 6.9%, p sarcopenia (odds ratio = 2.24, 95% confidence interval [CI] = 1.33-3.75). Polypharmacy is associated with clinically relevant sarcopenia, as assessed by a low ALM/BMI. © The Author 2017.

    To investigate the safety and effects of subconjunctival sirolimus, an mTOR inhibitor and immunosuppressive agent, for the treatment of geographic atrophy (GA). The study was a single-center, open-label phase II trial, enrolling 11 participants with bilateral GA; eight participants completed 24 months of follow-up. Sirolimus (440 μg) was administered every 3 months as a subconjunctival injection in only one randomly assigned eye in each participant for 24 months. Fellow eyes served as untreated controls. The primary efficacy outcome measure was the change in the total GA area at 24 months. Secondary outcomes included changes in visual acuity, macular sensitivity, central retinal thickness, and total drusen area. The study drug was well tolerated with few symptoms and related adverse events. Study treatment in study eyes was not associated with structural or functional benefits relative to the control fellow eyes. At month 24, mean GA area increased by 54.5% and 39.7% in study and fellow eyes, respectively (P = 0.41), whereas mean visual acuity decreased by 21.0 letters and 3.0 letters in study and fellow eyes, respectively (P = 0.03). Substantial differences in mean changes in drusen area, central retinal thickness, and macular sensitivity were not detected for all analysis time points up to 24 months. Repeated subconjunctival sirolimus was well-tolerated in patients with GA, although no positive anatomic or functional effects were identified. Subconjunctival sirolimus may not be beneficial in the prevention of GA progression, and may potentially be associated with effects detrimental to visual acuity.

    Introduction: Spasticity is a typical motor disorder in patients affected by stroke. Typically post-stroke rehabilitation consists of repetition of mobilization exercises on impaired limbs, aimed to reduce muscle hypertonia and mitigate spastic reflexes. It is currently strongly debated if the treatment's effectiveness improves with the timeliness of its adoption; in particular, starting intensive rehabilitation as close as possible to the stroke event may counteract the growth and postpone the onset of spasticity. In this paper we present a phase-II clinical validation of a robotic exoskeleton in treating subacute post-stroke patients. Methods: Seventeen post-stroke patients participated in 10 daily rehabilitation sessions using the NEUROExos Elbow Module exoskeleton, each one lasting 45 min: the exercises consisted of isokinetic passive mobilization of the elbow, with torque threshold to detect excessive user's resistance to the movement. We investigated the safety by reporting possible adverse events, such as mechanical, electrical or software failures of the device or injuries or pain experienced by the patient. As regards the efficacy , the Modified Ashworth Scale, was identified as primary outcome measure and the NEEM metrics describing elbow joint resistance to passive extension (i.e., maximum extension torque and zero-torque angle) as secondary outcomes. Results: During the entire duration of the treatments no failures or adverse events for the patients were reported. No statistically significant differences were found in the Modified Ashworth Scale scores, between pre-treatment and post-treatment and between post-treatment and follow-up sessions, indicating the absence of spasticity increase throughout (14 days) and after (3-4 months follow-up) the treatment. Exoskeleton metrics confirmed the absence of significant difference in between pre- and post-treatment data, whereas intra-session data highlighted significant differences in the secondary outcomes

  19. Significance of Neospora caninum in cattle farming

    Directory of Open Access Journals (Sweden)

    Ilić Tamara

    2006-01-01

    Full Text Available Neospora caninum is an obligate intracellular protozoan parasite which primarily causes diseases in dogs and cattle all over the world. It was first described in Norway in the mid-eighties in dogs, after which, until the present time, clinical neosporosis was proven in sheep, goats, deer, rhinoceroses, horses, and experimental rodents. Antibodies against N. caninum have been found also in the serum of water buffalo, red and gray foxes, coyotes, camels, and felines. Due to the similarity of this Coccidia with Toxoplasma gondi, the neosporosis was for a series of years incorrectly diagnozed as toxoplasmosis. Domestic canines, dogs, are the only real host for N. caninum. Its life cycle covers three stages of development: tachyzoites, tissue cysts and oocysts. Carnivores are infected by ingesting parts of infected tissue which contain tissue cysts with bradyzoites. The dominant pathway of transmission of this cause in cattle is transplacentary infection, but cattle can also be infected by ingestion of feed or water contaminated by sporulated oo-cysts of N. caninum. Bitches can be subclinical carriers of the parasite, when they pass on the cause transplacentarily, which results in more than one litter being born with the infection. Neosporosis today appears as the main cause of abortions and neonatal deaths in dairy cows and fattening cattle in almost all parts of the world, but with the highest incidence in the United States (US, New Zealand, The Netherlands, and Germany. The treatment of this disease has not been fully determined, but medicines used for the treatment of toxoplasmosis have yielded certain good results. There is no verified vaccine that would prevent undesired abortions in cattle. .

    Full Text Available Abstract Presenting processed antigens to CD4+ lymphocytes during the immune response involves major histocompatibility complex class II molecules. MHC class II genes transcription is regulated by four transcription factors: CIITA, RFXANK, RFX5 and RFXAP. Defects in these factors result in major histocompatibility complex class II expression deficiency, a primary combined immunodeficiency frequent in North Africa. Autosomal recessive mutations in the RFXANK gene have been reported as being the principal defect found in North African patients with this disorder. In this paper, we describe clinical, immunological and genetic features of 11 unrelated Algerian patients whose monocytes display a total absence of MHC class II molecules. They shared mainly the same clinical picture which included protracted diarrhoea and respiratory tract recurrent infections. Genetic analysis revealed that 9 of the 11 patients had the same RFXANK founder mutation, a 26 bp deletion (named I5E6-25_I5E6+1, also known as 752delG26. Immunological and genetic findings in our series may facilitate genetic counselling implementation for Algerian consanguineous families. Further studies need to be conducted to determine 752delG26 heterozygous mutation frequency in Algerian population.

    Domestic animals, including ruminants, can synthesize vitamin C (VC) in their liver; as such, the dietary requirement for VC has not been confirmed in these animals. The adequacy of VC has been evaluated by quantifying VC levels in plasma, but the reported values in bovine plasma have been widely variable. Plasma VC concentration is decreased by heat stress, hepatic lesions, fattening, and infectious diseases such as mastitis in cattle. Therefore, VC supplementation is potentially beneficial for cattle with low plasma VC concentration. This review discusses the methods for determination of plasma VC concentration in cattle, VC nutrition, and the efficacy of VC supplementation in calves, dairy cattle, and beef cattle. Additionally I propose a reference range for plasma VC concentration in Japanese Black cattle.

    A survey was conducted to better understand the contribution of farm productivity to rural household income and identify differences in production systems, feeding practices and development constraints to smallholder beef cattle producers in the four agro-ecological zones (AEZs) of Cambodia. A semi-structured questionnaire was used to interview 360 households in the four AEZs: I, the Great Lake Floodplain; II, the Mekong Floodplain; III, the Coastal and IV, the Plateau/Mountainous. In addition, samples of common nutritional resources used for cattle feed were collected for nutrient composition analysis, plus cattle were scored for body condition. Rice farming and cattle production were the most common sources of income in all AEZs. The average cattle herd size was 3.7 (SD = 2.4), but the majority of households raised 1-3 animals. The most common cattle management system was grazing with supplementation, mainly with rice straw and 'cut-and-carry' natural grasses fed during the wet season in all AEZs. The body condition score of all cattle types was 3.2 (SD = 0.8), except for cows in lactation that were 1.8. Major constraints to cattle production in AEZs I, II and III were lack of quality feed resources, capital for cattle production and concerns on breed quality, whereas in AEZ IV, diseases were identified as the main constraint. This survey confirms the importance of cattle to smallholders in the four AEZs. Interventions including farmer education to improve husbandry skills, increase the utilisation of forages and crop residues and address disease issues are necessary to enhance cattle production and rural livelihoods in Cambodia.

    Full Text Available Objective: The aim of the present study was to evaluate the effect of age, sex, location and management on cattle mortality rate in Rajshahi division of Bangladesh. Materials and methods: The study was conducted in 8 districts of Rajshahi division during July 2011 to June 2012. A total of 17,982 cattle heads were investigated based on age, sex, area. Data were collected from the cattle owners using a closed structured questionnaire. Tentative cause of cattle mortality was identified based on clinical signs, laboratory tests, history, ante-mortem and postmortem reports. Management practices of the cattle were also investigated. Results: Out of 17,982 cattle heads, 549 were found to be dead by various diseases, and an average mortality rate was 3.05%. Age-wise mortality rate of cattle revealed that the maximum mortality rate was found in the age group of 0.05 between the cattle mortality rate in Natore district (2.84% and Joypurhat districts (2.84%. Conclusion: The overall mortality rate of cattle in Rajshahi division was found comparatively low. This might be due to improved management practices, better veterinary services, and awareness among farmers. However, cattle mortality rate in the age group <2-year is alarming due to bad management practices and disease. [J Adv Vet Anim Res 2016; 3(1.000: 13-17

    The formation of biofilms and subsequent encasement of bacterial cells in a complex matrix can enhance resistance to antimicrobials and sterilizing agents making these organisms difficult to eradicate and control. The aim of this study was to evaluate and compare the capacity of 40 E. coli O26 isolates of enterohemorrhagic E. coli (EHEC, n = 27), potential EHEC (pEHEC, n = 3), atypical enteropathogenic E. coli (aEPEC, n = 8) and non-toxigenic E. coli (NTEC, n = 2) from human and cattle sources to form biofilms on different surfaces, and determine whether extracellular matrix (ECM) components (cellulose, curli), motility, prophage insertion in mlrA and cell surface hydrophobicity could influence biofilm formation. Finally, the influence of biofilm formation on the sensitivity of isolates to quaternary ammonium compounds (QACs; Profoam, Kwiksan 22) and peracetic acid-based sanitizer (Topactive Des.) for 2 min on polystyrene plate were also evaluated. Biofilm production on one surface may not indicate biofilm formation on a different surface. Biofilm was formed by different pathotypes on polystyrene (70%), stainless steel (87.5%) and glass slides (95%), however only 50% demonstrated pellicle formation. EHEC isolates were significantly more likely to form a pellicle at the air-liquid interface and biofilms on polystyrene surface at 48 h than aEPEC. Strains that don't produce ECM (curli or cellulose), harbor a prophage insertion in mlrA, and are non-motile have lower biofilm forming capacities than those isolates possessing combinations of these attributes. Hydrophobicity had no impact on biofilm formation. After 2 min exposure, none of the disinfectants tested were able to completely inactivate all cells within a biofilm regardless of pathotypes and the amount of biofilm formed. Pathotypes of E. coli O26 showed varying capacities to form biofilms, however, most EHEC strains had the capacity to form biofilm on all surfaces and at the air

    Full Text Available Major histocompatibility complex (MHC class II deficiency is a rare autosomal recessive form of primary immunodeficiency disorder (PID characterized by the deficiency of MHC class II molecules. This deficiency affects the cellular and humoral immune response by impairing the development of CD4+ T helper (Th cells and Th cell-dependent antibody production by B cells. Affected children typically present with severe respiratory and gastrointestinal tract infections. Hematopoietic stem cell transplantation (HSCT is the only curative therapy available for treating these patients. This is the first report from India wherein we describe the clinical, immunological, and molecular findings in five patients with MHC class II deficiency. Our patients presented with recurrent lower respiratory tract infection as the most common clinical presentation within their first year of life and had a complete absence of human leukocyte antigen-antigen D-related (HLA-DR expression on B cells and monocytes. Molecular characterization revealed novel mutations in RFAXP, RFX5, and CIITA genes. Despite genetic heterogeneity, these patients were clinically indistinguishable. Two patients underwent HSCT but had a poor survival outcome. Detectable level of T cell receptor excision circles (TRECs were measured in our patients, highlighting that this form of PID may be missed by TREC-based newborn screening program for severe combined immunodeficiency.

    Because of the potential treatment implications, it is clinically important to distinguish between bipolar II depression and major depressive disorder with comorbid borderline personality disorder. The high frequency of diagnostic co-occurrence and resemblance of phenomenological features has led some authors to suggest that borderline personality disorder is part of the bipolar spectrum. Few studies have directly compared patients with bipolar disorder and borderline personality disorder. In the present study from the Rhode Island Methods to Improve Diagnostic Assessment and Services project, we compared these 2 groups of patients on demographic, clinical, and family history variables. From December 1995 to May 2012, 3,600 psychiatric patients presenting to the outpatient practice at Rhode Island Hospital (Providence, Rhode Island) were evaluated with semistructured diagnostic interviews for DSM-IV Axis I and Axis II disorders. The focus of the present study is the 206 patients with DSM-IV major depressive disorder and borderline personality disorder (MDD-BPD) and 62 patients with DSM-IV bipolar II depression without borderline personality disorder. The patients with MDD-BPD were significantly more often diagnosed with posttraumatic stress disorder (P depression had a significantly higher morbid risk for bipolar disorder in their first-degree relatives than the MDD-BPD patients (P depression and major depressive disorder with comorbid borderline personality disorder differed on a number of clinical and family history variables, thereby supporting the validity of this distinction. © Copyright 2013 Physicians Postgraduate Press, Inc.

    Full Text Available Abstract Background In orthodontic treatment, anchorage control is a fundamental aspect. Usually conventional mechanism for orthodontic anchorage control can be either extraoral or intraoral that is headgear or intermaxillary elastics. Their use are combined with various side effects such as tipping of occlusal plane or undesirable movements of teeth. Especially in cases, where key-teeth are missing, conventional anchorage defined as tooth-borne anchorage will meet limitations. Therefore, the use of endosseous implants for anchorage purposes are increasingly used to achieve positional stability and maximum anchorage. Methods/Design The intended study is designed as a prospective, multicenter randomized controlled trial (RCT, comparing and contrasting the effect of early loading of palatal implant therapy versus implant loading after 12 weeks post implantation using the new ortho-implant type II anchor system device (Orthosystem Straumann, Basel, Switzerland. 124 participants, mainly adult males or females, whose diagnoses require temporary stationary implant-based anchorage treatment will be randomized 1:1 to one of two treatment groups: group 1 will receive a loading of implant standard therapy after a healing period of 12 week (gold standard, whereas group 2 will receive an early loading of orthodontic implants within 1 week after implant insertion. Participants will be at least followed for 12 months after implant placement. The primary endpoint is to investigate the behavior of early loaded palatal implants in order to find out if shorter healing periods might be justified to accelerate active orthodontic treatment. Secondary outcomes will focus e.g. on achievement of orthodontic treatment goals and quantity of direct implant-bone interface of removed bone specimens. As tertiary objective, a histologic and microtomography evaluation of all retrieved implants will be performed to obtain data on the performance of the SLA surface in human bone

    Context: Approved Clinical Instructors (ACIs; now known as preceptors) are expected to provide feedback to athletic training students (ATSs) during clinical education experiences. Researchers in other fields have found that clinical instructors and students often have different perceptions of actual and ideal feedback and that several factors may influence the feedback exchanges between instructors and students. However, understanding of these issues in athletic training education is minimal. Objective: To investigate the current characteristics and perceptions of and the influences on feedback exchanges between ATSs and ACIs. Design: Qualitative study. Setting: One entry-level master's degree program accredited by the Commission on Accreditation of Athletic Training Education. Patients or Other Participants: Four ACIs and 4 second-year ATSs. Data Collection and Analysis: Individual, semistructured interviews were conducted with participants and integrated with field notes and observations for analysis. We used the constant comparative approach to inductively analyze data and develop codes and categories. Member checking, triangulation, and peer debriefing were used to promote trustworthiness of the study. Results: Participants described that feedback plays an important role in clinical education and has several purposes related to improving performance. The ACIs and ATSs also discussed several preferred characteristics of feedback. Participants identified 4 main influences on their feedback exchanges, including the ACI, the ATS, personalities, and the learning environment. Conclusions: The ACIs and ATSs had similar perceptions of ideal feedback in addition to the actual feedback that was provided during their clinical education experiences. Most of the preferences for feedback were aligned with recommendations in the literature, suggesting that existing research findings are applicable to athletic training clinical education. Several factors influenced the

  13. The Spider Venom Peptide Lycosin-II Has Potent Antimicrobial Activity against Clinically Isolated Bacteria

    2016-04-01

    Full Text Available Antimicrobial peptides have been accepted as excellent candidates for developing novel antibiotics against drug-resistant bacteria. Recent studies indicate that spider venoms are the source for the identification of novel antimicrobial peptides. In the present study, we isolated and characterized an antibacterial peptide named lycosin-II from the venom of the spider Lycosa singoriensis. It contains 21 amino acid residue lacking cysteine residues and forms a typical linear amphipathic and cationic α-helical conformation. Lycosin-II displays potent bacteriostatic effect on the tested drug-resistant bacterial strains isolated from hospital patients, including multidrug-resistant A. baumannii, which has presented a huge challenge for the infection therapy. The inhibitory ability of lycosin-II might derive from its binding to cell membrane, because Mg2+ could compete with the binding sites to reduce the bacteriostatic potency of lycosin-II. Our data suggest that lycosin-II might be a lead in the development of novel antibiotics for curing drug-resistant bacterial infections.

    This study was conducted to determine the prevalence and characteristics of Listeria monocytogenes in the feces of black beef cattle reared in geographically distant areas in Japan. We surveyed 130 farms in the following three areas: northern (Hokkaido prefecture), central (Gifu and Mie prefectures), and southern (Oita, Miyazaki, and Kagoshima prefectures) areas and collected 1738 fecal samples. Our data showed the following isolation rate for each area: northern, 11.4% of 651; central, 2.8% of 572; and southern, 2.9% of 515, indicating that the isolation rate in the northern area was significantly higher than that in the central or southern areas (pprevalent serotype (40.5%), followed by 1/2a (36.9%), 4b (21.6%), and 4ab (1.0%). In the northern area, multiple serotypes were isolated from 60% of L. monocytogenes-positive farms. In addition, multiple serotypes were isolated from individual fecal samples from 18 cattle. Pulsed-field gel electrophoresis (PFGE) characterization of 239 isolates detected 48 different PFGE types. We found that isolates from northern farms were genetically diverse compared to those from central and southern farms. Five isolates from human clinical cases and three isolates from animal clinical cases were identical to isolates from black beef cattle. Furthermore, the isolates from northern and central farms were characterized to possess epidemic clone II or III markers. We next showed that the isolates were susceptible to penicillin, ampicillin, amoxicillin, gentamicin, kanamycin, streptomycin, erythromycin, vancomycin, tetracycline, chloramphenicol, ciprofloxacin, and trimethoprim/sulfamethoxazole. Taken together, our survey provides crucial data regarding the prevalence and characteristics of L. monocytogenes in black beef cattle farms throughout Japan.

    Cast Chromium Cobalt alloy has been the material of choice for fabricating Removable Partial Dentures (RPDs) but has certain drawbacks. Newer materials like the flexible Nylon based Super Polyamide have been introduced to overcome these drawbacks. The present study has compared the above two materials for nine clinical parameters. The study was carried out on 30 patients presenting with a Kennedy Applegate class II partially edentulous situation who were divided into two equal groups and clinically assessed. Statistically significant results were obtained in favor of flexible RPDs, in the parameters of 'aesthetics' and 'overall patient satisfaction'. Both groups showed more or less similar values for 'frequency of fracture of the prosthesis during usage' with the incidence being slightly higher for patients wearing the cast RPDs. The clinical parameters of 'oral soft tissue tolerance', 'gingival health', 'periodontal health' and 'adaptability in areas with undercut' were statistically at par for all the 30 patients thus suggesting the comparable biocompatibility of the two materials. The highlight of this study was the relative ease in fabrication of the flexible RPDs as compared to the cast RPDs. Based on the favorable clinical results of this study, it can be summarized that the flexible RPDs is a viable alternative to cast RPDs in Kennedy Applegate class II partially edentulous situation in the short term.

    Full Text Available Bovine papillomatosis is a viral disease of cattle characterized clinically by development of multiple benign tumours termed warts. The diagnosis of bovine papillomatosis was confirmed by clinical and pathological examinations of the warts. The prevalence of bovine papillomatosis in Northern Oases was recorded as 4.86%. The prevalence was higher in the females (2.99% than males (1.87%.The prevalence was the highest in cattle less than one year old (2.99%. The infected cattle were examined visually for detection of external parasites and faecal samples were examined for detection of internal parasites. Infestation with ticks was observed in 10 of the 13 confirmed wart infected animals, while fasciola and parasitic gastroenteritis (PGE nematode eggs were demonstrated and quantified in 4 and 5 infected bovids respectively. The statistical correlation between the number of warts and Fasciola eggs, and number of parasitic gastroenteritis (PGE nematode eggs, was 0.6 and 0.89 accordingly. Two therapeutic regimes were evaluated, regimen-I and regimen-II. All cattle treated were completely recovered in days post treatment 15 to 115. We concluded that treatment regimen-I was better than regimen-II when taking into consideration the mean days lapsed for healing and regression of warts of 42 days compared to 83 days for regimen-II.

    úbulos renais de bovinos pode ser causada pelo envenenamento por MF e, por analogia, essa substância deve ser considerada como um dos fatores importantes, senão o mais significativo, implicado na morte dos animais que ingerem plantas que causam morte súbita no Brasil. Isso indica que estudos, que envolvam metabolização de MF por bactérias ruminais, teriam grande aplicabilidade econômica, uma vez que pelo menos 500.000 bovinos morrem anualmente intoxicados por plantas do grupo das que causam morte súbita no Brasil.Sodium monofluoroacetate (MF was identified, by cromatography, in three of the 12 plants that cause sudden death in cattle in Brazil, including Palicourea marcgravii, the most important plant of this group. A special kind of hydropic-vacuolar degeneration (HVD of the distal convoluted uriniferous tubules was considered typical for the poisoning by some authors. The objective of this study was to verify if the ingestion of MF causes similar clinical signs and lesion in cattle poisoned by plants that cause sudden death. Six cows received orally 0.5 and 1.0mg/kg of M diluted in 50mL of distilled water. Clinically the animals presented tachycardia, engorgement and positive pulse of the jugular vein, abdominal breathing, swaying gait, subtle unbalance, and recumbency with head placed the on the flank. In the agonal phase all the animals in lateral recumbence presented muscular fasciculation, tonic contraction, peddling movements, opisthotonus, nystagmus, and died between 2 and 14 minutes. At postmortem examination, the heart auricles, jugular and pulmonary veins were moderately distended and engorged with blood. Slight to moderate edema of the subserosa was seen around the gall bladder and the duodenum near to the pancreas. At light microscopy, HVD associated with nuclear picnosis of the epithelial cells of the distal convoluted uriniferous tubules was present in all animals. Ultrastructurally, the cell lesion represents formation of cytosolic vacuoles, likely due

    the thoughts of breeders and other stakeholders on how to best make use of genomic breeding in the future. Intensive breeding has played a major role in securing dramatic increases in milk yield since the Second World War. Until recently, the main focus in dairy cattle breeding was on production traits...... it less accountable to the concern of private farmers for the welfare of their animals. It is argued that there is a need to mobilise a wide range of stakeholders to monitor developments and maintain pressure on breeding companies so that they are aware of the need to take precautionary measures to avoid...

    Clinical characteristics of fibromyalgia have so far been based mainly on patients identified in rheumatologic settings. This paper offers the clinical findings in fibromyalgia based on a national health interview survey, in which 123 persons fulfilled preset criteria for widespread pain. Clinical......, headache, difficulty in stair-climbing, and poorer self-evaluated health with more tender points was found. Contrary to that which was expected, fibromyalgia subjects did not suffer from sleep disturbances, irritable bowels or morning stiffness. Our findings indicate that clinical characteristics...... of fibromyalgia in the general population may differ from those found in rheumatological settings....

    Analysis of long-term anti-microbial resistance (AMR) data is useful to understand source and transmission dynamics of AMR. We analysed 5124 human clinical isolates from Washington State Department of Health, 391 cattle clinical isolates from the Washington Animal Disease Diagnostic Laboratory and 1864 non-clinical isolates from foodborne disease research on dairies in the Pacific Northwest. Isolates were assigned profiles based on phenotypic resistance to 11 anti-microbials belonging to eight classes. Salmonella Typhimurium (ST), Salmonella Newport (SN) and Salmonella Montevideo (SM) were the most common serovars in both humans and cattle. Multinomial logistic regression showed ST and SN from cattle had greater probability of resistance to multiple classes of anti-microbials than ST and SN from humans (P resistant ST and SN for people, occurrence of profiles unique to cattle and not observed in temporally related human isolates indicates these profiles are circulating in cattle only. We used various measures to assess AMR diversity, conditional on the weighting of rare versus abundant profiles. AMR profile richness was greater in the common serovars from humans, although both source data sets were dominated by relatively few profiles. The greater profile richness in human Salmonella may be due to greater diversity of sources entering the human population compared to cattle or due to continuous evolution in the human environment. Also, AMR diversity was greater in clinical compared to non-clinical cattle Salmonella, and this could be due to anti-microbial selection pressure in diseased cattle that received treatment. The use of bootstrapping techniques showed that although there were shared profiles between humans and cattle, the expected and observed number of profiles was different, suggesting Salmonella and associated resistance from humans and cattle may not be wholly derived from a common population. © 2014 The Authors.

    The aim of the present work was to examine a dairy herd with an anamnesis of recurrent clinical mastitis and decreased milk production. A total of 239 individual cow milk samples originating from asymptomatic cows were collected at four-month intervals and examined mainly for the presence of Staphylococcus aureus and mastitis streptococci using standard cultivation methods. In total, 29.7% and 9.2% samples were positive for S. aureus and mastitis streptococci, respectively. Unlike for mastitis streptococci, the prevalence of animals positive for S. aureus had an increasing trend (pmastitis, reproductive and periparturient disorders and administration of antibiotics. In contrast to S. aureus, the occurrence of mastitis streptococci in milk was linked with previous cases of clinical mastitis and intramammary administration of antibiotics.

    Objective: To explore the clinical significance of the changes of serum insulinlike growth factor II (IGF-II) levels in patients with chronic obstruive pulmonary diseases (COPD). Methods: The serum IGF-II levels was determined with radioimmunoassay in 60 patients with COPD and 30 controls. Results: The serum IGF-II levels in patients with COPD were significantly higher than those in controls (0.65 ± 0.22μg/L vs 0.51±0.18μg/L, P<0.01). There were no significant differences among the levels in patients of different stages (stages I, II, III). Levels of IGF-II were significantly higher in patients succumbed to the dis- ease than those in patients recoverd (P<0.05). Conclusion: Serum IGF-II levels were significantly increased in patients with COPD, especially in those succumbed. (authors)

    Objective: To evaluate the effects of fasting on anthropometric indices and carbohydrate and lipid metabolism in patients with type II diabetes. Results: Daily cholesterol intake increased in all subjects (p 0.01). Blood pressure, fasting blood glucose and serum fructosamine did not change during the study. Plasma insulin (p < 0.05), C-peptide (p < 0.01) and insulin resistance (p < 0.01) decreased only in men. Total and LDL cholesterol increased significantly in all subjects during the study. Conclusion: Ramadan fasting does not alter carbohydrate metabolism or tissue insulin sensitivity in patients with type II diabetes given appropriate dietary education and rescheduling of oral hypoglycaemic medication. Lipid profile is unfavorably altered due to changes in both diet and biochemical response to starvation. (author)

    Treatment-emergent affective switch (TEAS), including treatment-emergent mania (TEM), carry significant burden in the clinical management of bipolar depression, whereas the use of antidepressants raises both efficacy, safety and tolerability concerns. The present study assesses the prevalence and clinical correlates of TEM in selected sample of Bipolar Disorder (BD) Type-II (BD-II) acute depression outpatients. Post-hoc analysis of the clinical and psychopathological features associated with TEM among 91 BD-II depressed outpatients exposed to antidepressants. Second-generation antipsychotics (SGA) (p = .005), lithium (≤ .001), cyclothymic/irritable/hyperthymic temperaments (p = ≤ .001; p = .001; p = .003, respectively), rapid-cycling (p = .005) and depressive mixed features (p = .003) differed between TEM + cases vs. TEM - controls. Upon multinomial logistic regression, the accounted psychopathological features correctly classified as much as 88.6% of TEM + cases (35/91 overall sample, or 38.46% of the sample), yet not statistically significantly [Exp(B) = .032; p = ns]. Specifically, lithium [B = - 2.385; p = .001], SGAs [B = - 2.354; p = .002] predicted lower rates of TEM + in contrast to the number of lifetime previous psychiatric hospitalizations [B = 2.380; p = .002], whereas mixed features did not [B = 1.267; p = ns]. Post-hoc analysis. Lack of systematic pharmacological history record; chance of recall bias and Berkson's biases. Permissive operational criterion for TEM. Relatively small sample size. Cyclothymic temperament and mixed depression discriminated TEM + between TEM - cases, although only lithium and the SGAs reliably predicted TEM +/- grouping. Larger-sampled/powered longitudinal replication studies are warranted to allow firm conclusions on the matter, ideally contributing to the identification of clear-cut sub-phenotypes of BD towards patient-tailored-pharmacotherapy.

  15. Chemical control of ticks on cattle and the resistance of these parasites to acaricides.

    Science.gov (United States)

    George, J E; Pound, J M; Davey, R B

    2004-01-01

    Toward the end of the nineteenth century a complex of problems related to ticks and tick-borne diseases of cattle created a demand for methods to control ticks and reduce losses of cattle. The discovery and use of arsenical solutions in dipping vats for treating cattle to protect them against ticks revolutionized tick and tick-borne disease control programmes. Arsenic dips for cattle were used for about 40 years before the evolution of resistance of ticks to the chemical, and the development and marketing of synthetic organic acaricides after World War II provided superior alternative products. Most of the major groups of organic pesticides are represented on the list of chemicals used to control ticks on cattle. Unfortunately, the successive evolution of resistance of ticks to acaricides in each chemical group with the concomitant reduction in the usefulness of a group of acaricides is a major reason for the diversity of acaricides. Whether a producer chooses a traditional method for treating cattle with an acaricide or uses a new method, he must recognize the benefits, limitations and potential problems with each application method and product. Simulation models and research were the basis of recommendations for tick control strategies advocating approaches that reduced reliance on acaricides. These recommendations for controlling ticks on cattle are in harmony with recommendations for reducing the rate of selection for acaricide resistance. There is a need to transfer knowledge about tick control and resistance mitigation strategies to cattle producers.

    Kim et al. report two patients with melanoma metastases to the brain that responded to treatment with RRx-001 and whole brain radiotherapy (WBRT) without neurologic or systemic toxicity in the context of a phase I/II clinical trial. RRx-001 is an reactive oxygen and reactive nitrogen species (ROS/RNS)-dependent systemically nontoxic hypoxic cell radiosensitizer with vascular normalizing properties under investigation in patients with various solid tumors including those with brain metastases. Metastatic melanoma to the brain is historically associated with poor outcomes and a median survival of 4 to 5 months. WBRT is a mainstay of treatment for patients with multiple brain metastases, but no significant therapeutic advances for these patients have been described in the literature. To date, candidate radiosensitizing agents have failed to demonstrate a survival benefit in patients with brain metastases, and in particular, no agent has demonstrated improved outcome in patients with metastatic melanoma.

    Bovine besnoitiosis is an emerging protozoan disease in cattle. Neither vaccines nor chemotherapeutic drugs are currently available for prevention and treatment of Besnoitia besnoiti infections. Therefore the implementation of appropriate disease management strategies is of utmost importance. The aim of this longitudinal study was to complement current knowledge on the chronology of disease progression. This was realized by correlating clinical findings in early stages of naturally acquired bovine besnoitiosis with results of real-time PCR of skin biopsies and of two western immunoblots and an immunofluorescent antibody test (IFAT). Animals for this study were obtained by i) closely monitoring a cow-calf operation with a high prevalence of bovine besnoitiosis for cases of acute disease, and by ii) conducting a 12-week cohabitation experiment on pasture with five healthy heifers, a healthy bull and five B. besnoiti infected cows. A control group of six healthy heifers was kept at a minimal distance of 20 m. Further, the spectrum of potential insect vectors was determined. Infected cattle were followed up to a maximum of 221 days after first detection of B. besnoiti antibodies. Two severely affected cows developed visible and palpable alterations of skin, a decrease in body condition despite good feed intake, and chronic bovine besnoitiosis-associated laminitis leading to non-healing sole ulcers. The cows also had high reciprocal IFAT titers and high loads of parasite DNA in skin samples. Two heifers developed a mild clinical course characterized by few parasitic cysts visible in the scleral conjunctivae and vestibula vaginae. Both heifers became infected during the time of high insect activity of the species Musca domestica, Musca autumnalis, Haematobia irritans, and Stomoxys calcitrans. When a third heifer became subclinically infected, low insect activity was recorded. None of the six control heifers contracted a B. besnoiti infection. In chronic besnoitiosis

    The US regulations for production of organic milk include a strict prohibition against the use of antimicrobials and other synthetic substances. The effect of these regulations on dairy animal health has not been previously reported. The objective of this study was to characterize disease detection and identify risk factors for selected diseases on organic (ORG) and similarly sized conventional (CON) farms. Dairy herds (n=292) were enrolled across 3 states (New York, Oregon, Wisconsin) with CON herds matched to ORG herds based on location and herd size. During a single herd visit, information was collected about herd management practices and animal disease occurring in the previous 60 d, and paperwork was left for recording disease occurrences during 60 d after the visit. For analysis, CON herds were further divided into grazing and nongrazing. Poisson regression models were used to assess risk factors for rate of farmer-identified and recorded cases of clinical mastitis, ketosis, and pneumonia. An increased rate of farmer-identified and recorded cases of clinical mastitis was associated with use of CON management, use of forestripping, presence of contagious pathogens in the bulk tank culture, proactive detection of mastitis in postpartum cows, and stall barn housing. An increased rate of farmer-identified and recorded cases of ketosis was associated with having a more sensitive definition of ketosis, using stall barn housing, and feeding a greater amount of concentrates. An increased rate of farmer-identified and recorded cases of pneumonia was associated with a lack of grazing, small or medium herd size, and Jersey as the predominant breed. Overall, disease definitions and perceptions were similar among grazing systems and were associated with the rate of farmer-identified and recorded cases of disease.

    2017-11-01

    Full Text Available ABSTRACT: The aim of the present study was to describe an outbreak of atypical interstitial pneumonia affecting 15 Angus cattle aged 7-30 months in the south of Rio Grande do Sul. The clinical course of the disease was approximately 1-3 days. The cattle were kept in the native field and had received feed containing the remains of wafers from a food factory before the outbreak. Clinical signs included dyspnea and abdominal breathing, with a clinical evolution period of up to 3 days. Nine animals presented apathy and respiratory difficulty and died within 24h, while three animals exhibited a clinical evolution period of 36-48h. Three other animals died without any clinical signs. The main macroscopic lesions were observed in the lungs, which did not collapse at the opening of the thoracic cavity and showed a rubbery consistency. On the cut surface, the organs were firm and dark red, with marked distension of the interlobular septa due to edema. Histopathological analysis revealed thickening of the interlobular pulmonary septa; interstitial edema and emphysema; mild mononuclear cell, eosinophil, and neutrophil infiltration; areas of type II pneumocyte proliferation, and thickening of the alveolar walls. Fibrin was observed in the alveolar lumen with the formation of hyaline membranes. On the basis of macroscopic and histological examinations and epidemiological data, a final diagnosis of atypical interstitial pneumonia was made. Although, the cause of the disease has not been identified, it is believed that the bran wafer meal contained ingredients that were not suitable for animals, consequently triggering the disease.

    To describe the current state of knowledge concerning the quality of reporting in phase II clinical trials in oncology and to describe the various methods published allowing this quality evaluation. databases including MEDLINE and COCHRANE were searched. Reviews and meta-analyses analyzing the quality of the reporting of phase II trials in oncology were included. Descriptive analysis of the results was performed. Thirteen publications were retained. Only 2 publications adopted a systematic approach of evaluation of the quality of reporting by overall scores. The Key Methodological Score (KMS), proposed by Grellety et al., gathering 3 items, seemed adapted for such an evaluation. A score of 3/3 was found in 16.1% of the 156 phase II trials analysed by this score. The other reviews used a qualitative analysis to evaluate the reporting, via an analysis of a single criterion, generally the statistical plan of the study. This item was considered as having been correctly reported in less than 50% of the analysed articles. The quality of reporting in phase II trials in oncology is a field that has been investigated very little (13 publications). When it is studied, the estimated level of quality is not satisfactory, whatever the method employed. The use of an overall score of evaluation is a path which should be pursued, in order to get reliable results. It also seems necessary to propose strong recommendations, which would create a consensus for the methodology and the reporting of these studies. Copyright © 2018 Elsevier B.V. All rights reserved.

    RIPK2 mediates pro-inflammatory signaling from the bacterial sensors NOD1 and NOD2, and is an emerging therapeutic target in autoimmune and inflammatory diseases. We observed that cellular RIPK2 can be potently inhibited by type II inhibitors that displace the kinase activation segment, whereas ATP-competitive type I inhibition was only poorly effective. The most potent RIPK2 inhibitors were the US Food and Drug Administration-approved drugs ponatinib and regorafenib. Their mechanism of action was independent of NOD2 interaction and involved loss of downstream kinase activation as evidenced by lack of RIPK2 autophosphorylation. Notably, these molecules also blocked RIPK2 ubiquitination and, consequently, inflammatory nuclear factor κB signaling. In monocytes, the inhibitors selectively blocked NOD-dependent tumor necrosis factor production without affecting lipopolysaccharide-dependent pathways. We also determined the first crystal structure of RIPK2 bound to ponatinib, and identified an allosteric site for inhibitor development. These results highlight the potential for type II inhibitors to treat indications of RIPK2 activation as well as inflammation-associated cancers. Copyright © 2015 The Authors.

  10. BOP2: Bayesian optimal design for phase II clinical trials with simple and complex endpoints.

    Zhou, Heng; Lee, J Jack; Yuan, Ying

    2017-09-20

    We propose a flexible Bayesian optimal phase II (BOP2) design that is capable of handling simple (e.g., binary) and complicated (e.g., ordinal, nested, and co-primary) endpoints under a unified framework. We use a Dirichlet-multinomial model to accommodate different types of endpoints. At each interim, the go/no-go decision is made by evaluating a set of posterior probabilities of the events of interest, which is optimized to maximize power or minimize the number of patients under the null hypothesis. Unlike other existing Bayesian designs, the BOP2 design explicitly controls the type I error rate, thereby bridging the gap between Bayesian designs and frequentist designs. In addition, the stopping boundary of the BOP2 design can be enumerated prior to the onset of the trial. These features make the BOP2 design accessible to a wide range of users and regulatory agencies and particularly easy to implement in practice. Simulation studies show that the BOP2 design has favorable operating characteristics with higher power and lower risk of incorrectly terminating the trial than some existing Bayesian phase II designs.

    This paper describes about a study protocol of phase I/II multicenter prospective clinical trial evaluating the feasibility and efficacy of the hybrid of intracavitary and interstitial brachytherapy (HBT) for locally advanced uterine cervical cancer patients. Patients with histologically confirmed FIGO stage IB2, IIA2, IIB, and IIIB uterine cervical carcinoma width of which is larger than 5 cm assessed by MRI will be entered to this clinical trial. Protocol therapy is 30-30.6 Gy in 15-17 fractions of whole pelvic radiotherapy concurrent with weekly CDDP (40 mg/m(2)), followed by 24 Gy in 4 fractions of HBT and central shield EBRT up to 50-50.4 Gy in 25-28 fractions. Tumor width is assessed again within one week before the first HBT and if the tumor width is larger than 4 cm, patients proceed to the secondary registration. In phase I section, feasibility of this will be investigated. If less than 10 % out of 20 patients experienced greater than grade 3 acute non-hematologic adverse effects, the study proceeds to phase II part. In phase II part a total of 55 patients will be accrued and the efficacy of the HBT will be investigated comparing with historical control data. If the lower margin of 90 % confidence interval of the 2-year pelvic progression-free survival of the HBT trial is higher than 64 %, the HBT is considered to be more effective than conventional ICBT. The aim of this study is to demonstrate the feasibility and efficacy of the HBT for locally advanced cervical cancer. This trial will clarify the indication, feasibility, and efficacy of this new technique. UMIN000019081 ; Registration date: 2015/9/30.

    The aim of this short-term open parallel longitudinal clinical study was to compare the clinical and microbiological efficacy of 2 different antibiotic regimes in the treatment of acute periodontal abscesses. After patient selection, a clinical examination was carried out recording the following variables: pain, edema, redness, swelling, bleeding on probing, suppuration, tooth mobility, lymphadenopathy, and probing pocket depth. Microbiological samples were taken from the lesion and the patient was randomly assigned to one of two antibiotic regimes: azithromycin or amoxicillin/clavulanate. Clinical variables were recorded, and microbiological samples were taken, at 3-5 days, 10-12 days and 30 days. Additional mechanical treatment (debridement and scaling) was performed in the third visit (10-12 days). Blood and urine samples were collected at baseline and after 10-12 days. Microbiological samples were processed by anaerobic culturing, and isolated periodontal pathogens were tested for antibiotic susceptibility by means of the spiral gradient endpoint methodology. 15 patients took azithromycin, and 14 amoxicillin/clavulanate. Subjective clinical variables demonstrated statistically significant improvements with both antibiotic regimes, which lasted for at least 1 month (pperiodontal abscesses in periodontitis patients.

    Full Text Available Sixteen outbreaks of Senna occidentalis (coffee senna that occurred in cattle in the state of Rio Grande do Sul, Brazil, were reviewed. The great majority (75% of the outbreaks occurred in adult cattle at pasture during the autumn and winter months with 50% in May, evidencing a striking seasonality. Mortality rates varied from 4.2% to 55.2% and cattle died 2 days up to 2 weeks after showing clinical signs that included dry feces (occasionally diarrhea, muscle weakness, reluctance to move, tachypnea, instability of the hind limbs with dragging of the toes, tremors in muscles of the thighs, neck, and head, ear dropping, sternal recumbency, lateral recumbency and death. Myoglobinuria characterized by a dark red or black discolored urine was a consistent finding in cattle affected at pasture but not in those poisoned by ration contaminated with coffee senna beans. Creatine phosphokinase serum activity was marked ly elevated. Main gross changes observed in 23 necropsies involved skeletal muscles of the hind limbs. These changes consisted of varying degrees of paleness of muscle groups. Subepicardial and subendocardial hemorrhages were present in the hearts of all affected cattle. Histologically a segmental degenerative myopathy of striated muscles was present in every case and had a multifocal polyphasic or monophasic character. Myocardial (3/23, hepatic (3/13, renal (3/10, and splenic (1/6 microscopic lesions were observed occasionally. Myocardial lesions were mild and consisted of vacuolation of cardiomyocytes or focal fibrosis. Hepatic changes consisted of diffuse hepatocelular vacuolation, cytosegrosomes within hepatocytes, and individual hepatocellular necrosis. Kidneys had vacuolar degeneration of tubular epithelium associated with acidophilic casts (proteinosis within tubular lumina. In the spleen there was marked necrosis of lymphocytes of the white pulp. No histological changes were found in the brains of 13 affected cattle. The data of this

    The hocks of tied cows of a Swedish dairy herd of different breeds were radiographed. Osteoarthrosis of the arthrodial joints (spavin) was found in 37% of the animals. Changes were seen before the cows were 2 yr old, and they increased in severity with increasing age. Macroscopic and histologic examination revealed that there was osteoarthrosis also in many radiologically normal hocks. The frequency of spavin in tied dairy cows is higher than clinical signs indicate. Only cows with fusion of the arthrodial joints show the stiff hind leg movements considered typical of spavin. Differences in the incidence of spavin were found between the different breeds. Cows of the Swedish Friesian breed had the lowest (20%) and cows of the Jersey breed had the highest (50%) incidence of spavin. As regards the Jersey breed this was due to the high incidence (71%) found in cows raised on a high intensity feeding during the young stock period. Among the SJB [Swedish Jersey] cows raised on a normal intensity feeding the incidence of spavin was 25%. Such a relationship between high young stock feeding intensity and the incidence of spavin was not seen within the other breeds. The cows in another herd with loose housing had a lower frequency of spavin than the tied cows. Offspring of animals with spavin had a higher incidence of spavin than the offspring of animals without spavin. (author)

    The life expectancy of patients with disorders of consciousness (DOCs) is ever-increasing, but little is known about their clinical course over late stages. Several issues (premorbid conditions, complications and pressure sores) are to be considered for their effect on clinical outcome, risk of death and recovery of functional performance. Unfortunately, in late stages of long-term rehabilitation, these aspects are still more neglected than in acute and postacute stages. The aim of this study was to investigate the clinical course and the complications of patients in the late stages of DOCs and to explore the relationship between mortality and specific biomarkers. A total of 112 patients, admitted over 10 years in a dedicated ward, were retrospectively studied. Sociodemographic data, preadmission and inpatient clinical features were collected. Disability Rating Scale scores, complications including pressure sores and blood markers were assessed monthly. Data were analyzed through descriptive statistics and correlations using SPSS. Most patients were men older than 50 years with a nontraumatic etiology and a history of hypertension (42.86%). The most common complication was pneumonia (76.79%). No association was found between sex and mortality or between etiology and mortality (P > 0.05). Mortality correlated significantly with sepsis (ρ = 0.253), albumin (ρ = -0.558), hemoglobin (ρ = -0.354) and white blood cells (ρ = 0.243). Only 42% of patients remained unchanged at Disability Rating Scale evaluation. These data confirmed that DOCs are not static conditions and they require ongoing monitoring and assessment of clinical status, level of consciousness and laboratory biomarkers.

  17. "Subclinical" laminitis in dairy cattle.

    Science.gov (United States)

    Vermunt, J J

    1992-12-01

    In dairying countries worldwide, the economic importance of lameness in cattle is now recognised. Laminitis is regarded as a major predisposing factor in lameness caused by claw disorders such as white zone lesions, sole ulcer, and heel horn erosion. The existence of subclinical laminitis was first suggested in the late 1970s by Dutch workers describing the symptoms of sole haemorrhages and yellowish-coloured, soft sole horn. In an attempt to clarify some of the confusing and often conflicting terminology, the literature on laminitis is reviewed. Disturbed haemodynamics, in particular repeated or prolonged dilation of arteriovenous anastomoses, have been implicated in the pathogenesis of both equine and bovine laminitis. Some characteristics of the vascular system of the bovine claw which may be of importance in the pathophysiology of the subclinical laminitis syndrome are therefore discussed. Clinical observations suggest that subclinical laminitis is a multifactorial disease. The different factors that are or may be involved in its aetiology vary in complexity and severity according to the management protocol of the animals. The possible involvement of subclinical laminitis in claw lesions is assessed.

    A 4.75-year old Simmental cow was presented with symptoms of colic and ileus. The clinical signs and blood analysis resulted in the diagnosis of suspected primary hypoadrenocorticism (Addison's disease). Although Addison's disease has been frequently described in other domestic mammals, to our knowledge, this disease has not previously been reported in cattle.

    To explore the molecular etiology of two pedigrees affected with type II Waardenburg syndrome (WS2) and to provide genetic diagnosis and counseling. Blood samples were collected from the proband and his family members. Following extraction of genomic DNA, the coding sequences of PAX3, MITF, SOX10 and SNAI2 genes were amplified with PCR and subjected to DNA sequencing to detect potential mutations. A heterozygous deletional mutation c.649_651delAGA in exon 7 of the MITF gene has been identified in all patients from the first family, while no mutation was found in the other WS2 related genes including PAX3, MITF, SOX10 and SNAI2. The heterozygous deletion mutation c.649_651delAGA in exon 7 of the MITF gene probably underlies the disease in the first family. It is expected that other genes may also underlie WS2.

    An attenuated live vaccine containing Babesia bovis and B. bigemina cultured in vitro with a serum-free medium was assessed for its clinical protection conferred of naïve cattle, under natural tick-challenge in a high endemicity zone to Babesia spp. Three groups of six animals were treated as follows: group I (GI) received a vaccine derived from parasites cultured with a free-serum medium; group II (GII) were immunized with the standard vaccine, with parasites cultured in a medium supplemented with 40% (v/v) bovine serum; and a control group (GIII) inoculated with non-infected bovine erythrocytes. Inocula were administered by IM route. Experimental animals were kept during 23days after vaccination in a cattle farm free of ticks and Babesia spp. Thereafter, cattle were moved to a high endemicity farm for natural exposure to Babesia spp. transmitted by Rhipicephalus microplus ticks. Protection against clinical babesiosis was observed in bovines belonging to GI (100%) and GII (83.33%), while the control animals (GIII) were not protected, and showed severe clinical signs, closely related to babesiosis, were observed for at least three consecutive days during the challenge. These were fever, anemia, which were measured simultaneously, and circulating parasites were detected by optic light microscopy. All cattle showed B. bovis and B. bigemina in stained blood films during the challenge; B. bovis antibody titers were higher than those to B. bigemina in GI and GII, and lower titers were determined in GIII. The protective capacity of the vaccine derived from B. bovis and B. bigemina cultured in vitro in a serum-free medium was demonstrated. Copyright © 2017 Elsevier B.V. All rights reserved.

    The clinical records of 420 patients with diagnosis of breast cancer well documented by the pathological anatomy in clinical stage II, III and IV were reviewed. In each one of them has been done at least a bone scanning during the diagnosis. In 52 cases carried out sericeous dosages of CA 15-3 and in some cases it was necessary to administer Samarium-153 EDTMP as palliative therapy of bone pain. The presence of secondary gamma-graphic focuses was 0/84 cases (0%) in clinical stage II, 54/265 cases (20%) in III and 41/91 cases (45%) in IV. The one focus appeared in 6.7% of the cases. In 7 of the 52 cases that received sericeous dosages of CA 15-3 were detected secondary osseous lesions, and 5 of them presented a marker elevation. The bone scanning has shown in many cases the presence of getters focuses in singular places of skeleton, urinary excretory system or mammary tissue. The gamma rays from Sm-153 allowed us to get some appropriate basal views post-therapy of the secondary lesions. The results show that the great incidence of secondary lesions in the skeleton occurred in cases of stages III and IV unlike other countries. The serial repetition of the radioisotope scanning. The presence of one focus in the skeleton of a patient with a well-known neoplasia makes us to do a careful evaluation of the focus nature. The presence of tracer accumulation in the kidney, ureter and bladder allows us to infer the pathology of excretory system that is the first evidence of its presence in many cases.

  3. Industrial fluoride pollution: chronic fluoride poisoning in Cornwall Island cattle

    Krook, L.; Maylin, G.A.

    1979-04-01

    An aluminum plant on the south bank of the St. Lawrence River, southwest of Cornwall Island, Ontario, Canada, has emitted 0.816 metric tons of fluoride daily since 1973. Considerably higher amounts were emitted from 1959 to 1973. The plant was designated as the major source of fluoride emissions impacting on Cornwall Island. Cattle located on this island showed signs of chronic fluoride poisoning. This poisoning was manifested clinically by stunted growth and dental fluorosis to a degree of severe interference with drinking and mastication. This Cornwall Island herds study indicates that the established tolerance level of fluoride for performance of dairy and beef cattle is not valid since the tolerance level was set based on experiments with healthy calves which were exposed to dietary fluoride from 3 to 4 months of age and not on cattle which were chronically exposed to fluoride from conception to death. 56 references.

    For the past 40 years, liposomal and polymeric delivery vehicles have been studied as systems capable of modulating the cytotoxicity of small molecule chemotherapeutics, increasing tumor bearing animal survival times, and improving drug targeting. Although a number of macromolecular-drug conjugates have progressed to clinical trials, tuning drug release to maintain efficacy in conjunction with controlling drug toxicity has prevented the clinical adoption of many vehicles. In this article, we review the motivations for and approaches to polymer and liposomal delivery with regard to camptothecin and cisplatin delivery.

    Distress and senescence, their reciprocal aggravating-quickening connections, and their related pathologies have a large worldwide impact on healthcare systems in this new millennium. For this reason, Antagonic-Stress (AS)--an advanced integrative therapy, with specific synergistic composition, and patented internationally--represents a significant strategy in health, aging, and longevity. Clinical research with AS proves the drug's efficacy in the management of distress (neurotic, stress-related, and affective disorders; behavioral syndromes associated with physiological disturbances and physical factors; mental and behavioral disorders due to psychoactive substance uses) and psychogeriatrics [organic, including symptomatic, mental disorders (OMD)]. Specific multiaxial psychopathological instruments and psychometric tests in multiple assessments used for gerontopsychiatry demonstrated strong improvements after AS administration in early-moderate stages of Alzheimer or vascular dementia, as well as in other OMD. In addition, comparative clinical studies evinced the superiority of AS (synergistic multitherapy) versus monotherapy [meclofenoxate (MF), piracetam (PA), pyritinol (PT), and nicergoline (NE), respectively]. These comparative clinical trials agreed closely with comparative preclinical research and confirmed AS synergistic homeostatic, adaptogenic, antioxidative, cerebrovascular, neurometabolic, and nootropic actions. Also, the AS protective actions against oxidative stress recommend this orthomolecular therapy in stress, aging, and free radical pathology.

    2012-04-01

    Kinematic multi-segment foot models have seen increased use in clinical and research settings, but the addition of kinetics has been limited and hampered by measurement limitations and modeling assumptions. In this second of two companion papers, we complete the presentation and analysis of a three segment kinetic foot model by incorporating kinetic parameters and calculating joint moments and powers. The model was tested on 17 pediatric subjects (ages 7-18 years) during normal gait. Ground reaction forces were measured using two adjacent force platforms, requiring targeted walking and the creation of two sub-models to analyze ankle, midtarsal, and 1st metatarsophalangeal joints. Targeted walking resulted in only minimal kinematic and kinetic differences compared with walking at self selected speeds. Joint moments and powers were calculated and ensemble averages are presented as a normative database for comparison purposes. Ankle joint powers are shown to be overestimated when using a traditional single-segment foot model, as substantial angular velocities are attributed to the mid-tarsal joint. Power transfer is apparent between the 1st metatarsophalangeal and mid-tarsal joints in terminal stance/pre-swing. While the measurement approach presented here is limited to clinical populations with only minimal impairments, some elements of the model can also be incorporated into routine clinical gait analysis.

    Full Text Available Abstract Background Ipilimumab, a fully human monoclonal antibody that blocks cytotoxic T-lymphocyte antigen-4, has demonstrated an improvement in overall survival in two phase III trials of patients with advanced melanoma. The primary objective of the current trial was to prospectively explore candidate biomarkers from the tumor microenvironment for associations with clinical response to ipilimumab. Methods In this randomized, double-blind, phase II biomarker study (ClinicalTrials.gov NCT00261365, 82 pretreated or treatment-naïve patients with unresectable stage III/IV melanoma were induced with 3 or 10 mg/kg ipilimumab every 3 weeks for 4 doses; at Week 24, patients could receive maintenance doses every 12 weeks. Efficacy was evaluated per modified World Health Organization response criteria and safety was assessed continuously. Candidate biomarkers were evaluated in tumor biopsies collected pretreatment and 24 to 72 hours after the second ipilimumab dose. Polymorphisms in immune-related genes were also evaluated. Results Objective response rate, response patterns, and safety were consistent with previous trials of ipilimumab in melanoma. No associations between genetic polymorphisms and clinical activity were observed. Immunohistochemistry and histology on tumor biopsies revealed significant associations between clinical activity and high baseline expression of FoxP3 (p = 0.014 and indoleamine 2,3-dioxygenase (p = 0.012, and between clinical activity and increase in tumor-infiltrating lymphocytes (TILs between baseline and 3 weeks after start of treatment (p = 0.005. Microarray analysis of mRNA from tumor samples taken pretreatment and post-treatment demonstrated significant increases in expression of several immune-related genes, and decreases in expression of genes implicated in cancer and melanoma. Conclusions Baseline expression of immune-related tumor biomarkers and a post-treatment increase in TILs may be positively associated with

    Purpose: HAb18G/CD147 is a hepatocellular carcinoma (HCC)-associated antigen. We developed iodine ( 131 I) metuximab injection (Licartin), a novel 131 I-labeled HAb18G/CD147-specific monoclonal antibody F(ab') 2 fragment, and evaluated its safety, pharmacokinetics, and clinical efficacy on HCC in Phase I/II trials. Methods and Materials: In a Phase I trial, 28 patients were randomly assigned to receive the injection in 9.25-, 18.5-, 27.75-, or 37-MBq/kg doses by hepatic artery infusion. In a multicenter Phase II trial, 106 patients received the injection (27.75 MBq/kg) on Day 1 of a 28-day cycle. Response rate and survival rate were the endpoints. Results: No life-threatening toxic effects were found. The safe dosage was 27.75 MBq/kg. The blood clearance fitted a biphasic model, and its half-life was 90.56-63.93 h. In the Phase II trial, the injection was found to be targeted and concentrated to tumor tissues. Of the 73 patients completing two cycles, 6 (8.22%) had a partial response, 14 (19.18%) minor response, and 43 (58.90%) stable disease. The 21-month survival rate was 44.54%. The survival rate of progression-free patients was significantly higher than that of patients with progressive disease after either one or two cycles (p 131 I) metuximab injection is safe and active for HCC patients

    Patients with chronic kidney disease mineral and bone disorders (CKD-MBD) suffer high rates of morbidity and mortality, in particular related to bone and cardiovascular outcomes. The management of CKD-MBD remains challenging. The objective of this systematic survey is to critically appraise clinical practice guidelines (CPGs) addressing CKD-MBD. Data sources included MEDLINE, EMBASE, the National Guideline Clearinghouse, Guideline International Network and Turning Research into Practice up to May 2016. Teams of two reviewers, independently and in duplicate, screened titles and abstracts and potentially eligible full text reports to determine eligibility and subsequently appraised the guidelines using the Advancing Guideline Development, Reporting and Evaluation in Health Care instrument II (AGREE). Sixteen CPGs published from 2003 to 2015 addressing the diagnosis and management of CKD-MBD in adult patients (11 English, two Spanish, one Italian, one Portuguese and one Slovak) proved eligible. The National Institute for Health and Care Excellence guideline performed best with respect to AGREE II criteria; only three other CPGs warranted high scores on all domains. All other guidelines received scores of under 60% on one or more domains. Major discrepancies in recommendations were not, however, present, and we found no association between quality of CPGs which was not associated with resulting recommendations. Most guidelines assessing CKD-MBD suffer from serious shortcomings using AGREE criteria although limitations with respect to AGREE criteria do not necessarily lead to inappropriate recommendations.

    In the current study, we evaluated the associations between the Minnesota Multiphasic Personality Inventory-2 Restructured Form (MMPI-2-RF; Ben-Porath & Tellegen, 2008) scale scores and the Diagnostic and Statistical Manual of Mental Disorders (5th ed.; DSM-5; American Psychiatric Association, 2013) Section II personality disorder (PD) criterion counts in inpatient and forensic psychiatric samples from The Netherlands using structured clinical interviews to operationalize PDs. The inpatient psychiatric sample included 190 male and female patients and the forensic sample included 162 male psychiatric patients. We conducted correlation and count regression analyses to evaluate the utility of relevant MMPI-2-RF scales in predicting PD criterion count scores. Generally, results from these analyses emerged as conceptually expected and provided evidence that MMPI-2-RF scales can be useful in assessing PDs. At the zero-order level, most hypothesized associations between Section II disorders and MMPI-2-RF scales were supported. Similarly, in the regression analyses, a unique set of predictors emerged for each PD that was generally in line with conceptual expectations. Additionally, the results provided general evidence that PDs can be captured by dimensional psychopathology constructs, which has implications for both DSM-5 Section III specifically and the personality psychopathology literature more broadly.

    Zohar, Sarah; Chevret, Sylvie

    2003-02-01

    We propose a new design for phase I (or phase II) dose-ranging clinical trials aiming at determining a dose of an experimental treatment to satisfy safety (respectively efficacy) requirements, at treating a sufficiently large number of patients to estimate the toxicity (respectively failure) probability of the dose level with a given reliability, and at stopping the trial early if it is likely that no dose is safe (respectively efficacious). A two-stage design was derived from the Continual Reassessment Method (CRM), with implementation of Bayesian criteria to generate stopping rules. A simulation study was conducted to compare the operating characteristics of the proposed two-stage design to those reached by the traditional CRM. Finally, two applications to real data sets are provided.

    To frame and study sociomedical evaluations in clinical work with unemployed people. In a two-year follow up of routine health examinations, three sociomedical evaluations were set up. The first was the direct conclusion of the check-up, based on sickness and possibilities of treatment. The second dealt with work identity, and the last was a diagnostic set of main unemployment problem. The four municipalities of Grenland, Norway. A representative sample aged 16 to 63 who had been registered with the labour market authorities for more than 12 weeks. 21% of the unemployed needed further treatment. 7% were classified as "discouraged", being on their way out of the labour market, while the majority of the study group was healthy job seekers. Work identity seemed to be wage earning for 83%, homemaking for 9%, cultural work for 3%, and being a pensioner for 5%. The main unemployment problem was lack of work for 46% of the examined. Other problems were poor health, being less attractive workers, or having little courage for job search. The evaluations predicted re-employment after two years. They divided the unemployed in groups with from five to seven times difference in re-employment rate. These standardized sociomedical evaluations seen to be useful in clinical work with unemployed people.

    The second article in this series, Standards for Clinical Trials in Male and Female Sexual Dysfunction, focuses on measurement of patient-reported outcomes (PROs). Together with the design of appropriate phase I to phase IV clinical trials, the development, validation, choice, and implementation of valid PRO measurements-the focus of the present article-form the foundation of research on treatments for male and female sexual dysfunctions. PRO measurements are assessments of any aspect of a patient's health status that come directly from the patient (ie, without the interpretation of the patient's responses by a physician or anyone else). PROs are essential for assessing male and female sexual dysfunction and treatment response, including symptom frequency and severity, personal distress, satisfaction, and other measurements of sexual and general health-related quality of life. Although there are some relatively objective measurements of sexual dysfunction (ie, intravaginal ejaculatory latency time, frequency of sexual activity, etc), these measurements do not comprehensively assess the occurrence and extent of sexual dysfunction or treatment on the patient's symptoms, functioning, and well-being. Data generated by a PRO instrument can provide evidence of a treatment benefit from the patient's perspective. Copyright © 2016 International Society for Sexual Medicine. Published by Elsevier Inc.

    This article is a continuation of the previous module on designing questionnaires and clinical record form in which we have discussed some basic points about designing the questionnaire and clinical record forms. In this section, we will discuss the reliability and validity of questionnaires. The different types of validity are face validity, content validity, criterion validity, and construct validity. The different types of reliability are test-retest reliability, inter-rater reliability, and intra-rater reliability. Some of these parameters are assessed by subject area experts. However, statistical tests should be used for evaluation of other parameters. Once the questionnaire has been designed, the researcher should pilot test the questionnaire. The items in the questionnaire should be changed based on the feedback from the pilot study participants and the researcher's experience. After the basic structure of the questionnaire has been finalized, the researcher should assess the validity and reliability of the questionnaire or the scale. If an existing standard questionnaire is translated in the local language, the researcher should assess the reliability and validity of the translated questionnaire, and these values should be presented in the manuscript. The decision to use a self- or interviewer-administered, paper- or computer-based questionnaire depends on the nature of the questions, literacy levels of the target population, and resources.

    Full Text Available BACKGROUND The present research was undertaken to study the pattern of dyslipidaemia and varied clinical manifestations of ischaemic heart disease, its risk factors in type 2 diabetes mellitus patients. Diabetes Mellitus (DM has become major public health problem in India. It is not only increasing in morbidity and mortality, but also decreases the quality of life. Also, disease and its complications are causing heavy economic burden for patients suffering from it.1,2 Diabetes is endemic globally with increasing prevalence in both developing and developed countries. Diabetes is a major cause of mortality, but several studies indicate that it is likely underreported as a cause of death. A recent estimate suggested that diabetes was the fifth leading cause of death worldwide and was responsible for almost 3 million deaths annually (1.7-5.2% of all deaths. MATERIALS AND METHODS A total of 100 patients attending the outpatient department or admitted to medical wards, ICU of tertiary care centre and fulfilling the inclusion criteria were evaluated clinically. A baseline Electrocardiogram (ECG was taken in all cases irrespective of clinical evidence of cardiac involvement. Patients with normal ECG pattern were further evaluated by Treadmill Testing (TMT or stress test for subclinical cardiac involvement. Risk factor evaluation was done in all cases. RESULTS Prevalence of IHD was found to be 41% with a male predominance (1.067:1. Evaluation of risk factors has shown its strong association with IHD. Incidence of IHD was high when low HDL (P 25 had negatively significant association with IHD in type 2 diabetics (P=0.072. Smoking was not statistically associated (P=0.577 and in male alcoholics, IHD had positive association with alcohol (P=0.193. CONCLUSION The current study points out that there exists an increased incidence of ischaemic heart disease in diabetics with few, but not all risk factors contributing to it.

    Objective: To explore the clinical significance of determination of changes of serum IGF-II, GM-CSF and TNF- α levels after treatment in children with acute nephritis. Methods: Serum IGF-II, GM-CSF and TNF-α levels (with RIA) were measured in 31 pediatric patients with acute nephritis and 35 controls. Results: Before treatment, the serum IGF-II, GM-CSF and TNF-α levels in the patients were significantly higher than those in controls (P< O.01). After treatment for 3 months, the serum IGF-II, GM-CSF and TNF-α levels, though markedly corrected, remained significantly higher than those in controls (P<0.05). Conclusion: Determination of changes of serum IGF-II, GM-CSF and TNF-α contents after treatment might be of prognostic importance in pediatric patients with acute nephritis. (authors)

    Objective: To study the clinical significance of changes of serum IGF-II, EGF and CYFRA21-1 levels after chemotherapy in patients with lung cancer. Methods: Serum IGF-II, EGF (with RIA), and CYFRA21-1 (with ECLIA) levels were determined both before and after chemotherapy in 39 patients with lung cancer as well as once in 35 controls. Results: Before chemotherapy, serum IGF-II, EGF and CYFRA21-1 levels were significantly higher in the patients than those in controls(P<0.01). Six months after chemotherapy, serum IGF-II, EGF and CYFRA21-1 levels dropped markedly, but remained significantly higher than those in controls(P<0.05). Conclusion: The development of lung cancer in patients was closely related to the serum IGF-II, EGF and CYFRA21-1 levels. (authors)

    Full Text Available Senecio spp. poisoning is the main cause of cattle mortality in the central region of Rio Grande do Sul. This paper reports an outbreak of seneciosis in cattle with high prevalence of photosensitization, where 83 out of 162 cows (51.3% presented this clinical sign. The outbreak occurred in September 2013, affecting adult cows that were held in a 205 hectare-pasture from April to October 2013 with abundant Senecio brasiliensis infestation. Main clinical signs were weight loss, excessive lacrimation or mucopurulent ocular discharge, nasal serous discharge, ventral diphteric glossitis, crusts in the nose, teats, dorsum of ears, and vulva. Liver biopsy was performed in all the cows under risk; the histopathological findings in the liver biopsies consisted of fibrosis, megalocytosis, and biliary ductal proliferation and were present in 73.4% of the biopsied animals. Six cows had increased serum activity of gamma glutamyl transferase. Three affected cows were necropsied. The main necropsy findings were a hard liver, distended gall bladder, edema of the mesentery and abomasum. Liver histological changes in the necropsied cows were similar to those of the biopsied livers. Spongiosis was detected in the brain of necropsied cows and is characteristic of hepatic encephalopathy.

    Full Text Available Epidural analgesia is commonly used in large animals. It is an easy, cheap, and effective technique used to prevent or control pain during surgeries involving the tail, anus, vulva, perineum, caudal udder, scrotum, and upper hind limbs. The objectives of this article were to comprehensively review and summarize all scientific data available in the literature on new techniques and drugs or drug combinations used for epidural anesthesia in cattle, camel, and buffalo. Only articles published between 2006 and 2016 were included in the review. The most common sites for epidural administration in cattle, camels, and buffalos were the sacrococcygeal intervertebral space (S5-Co1 and first intercoccygeal intervertebral space (Co1-Co2. The most frequently used drugs and dosages were lidocaine (0.22-0.5 mg/kg, bupivacaine (0.125 mg/kg, ropivacaine (0.11 mg/kg, xylazine (0.05 mg/kg, medetomidine (15 μg/kg, romifidine (30-50 μg/kg, ketamine (0.3-2.5 mg/kg, tramadol (1 mg/kg, and neostigmine (10 μg/kg, and the clinical applications, clinical effects, recommendations, and side effects were discussed.

    Clinical picture of development of segmental blocking after subarachnoidal injection of hyperbaric solutions of 0.75% bupivacaine, 5% ultracaine, and isobaric 0.5% bupivacaine is studied. A total of 152 patients operated on the lower part of the body and the lower limbs were examined under conditions of single, prolonged subarachnoidal, and combined spinal epidural anesthesia. Ultracaine and bupivacaine in different concentrations with different barism provided anesthesia equivalent by the efficacy, depth, and dissemination of sensory block. Segmental blocking with 5% ultracaine was characterized by the shortest latent period (3.14 +/- 0.16 min, p anesthesia in comparison with a single injection, and combined spinal epidural anesthesia shortened the latent period of segmental blocking and ensured intraoperative anesthesia and postoperative analgesia at the expense of the epidural component.

As condutas descritas são opções viáveis para o tratamento dos deslocamentos leves e severos, no entanto a prevenção permanece a melhor alternativa a ser adotada.The continuous genetic selection for high milk production in association with greater digestive capacity and corporal depth increases the susceptibility for abomasopathies including abomasal displacement. The present work aimed to accomplish a retrospective study on abomasal displacement in 36 cattle attended at Bovine Clinic, Garanhuns Campus, Federal Rural University of Pernambuco, through January 2000 to February 2009. Twenty seven cases of right abomasal displacement, six cases of left abomasal displacement and three of abomasal volvulus were diagnosed. Eleven moderate cases, without severe abdominal distention, appetite for roughage and metallic sound (“ping” reaching at the most the 8th intercostal space were treated conservatively, and 20 severe cases with moderate to severe abdominal distention associated to systemic disturbances were treated surgically. Two cows were euthanized due to diffuse peritonitis or severe alterations in the abomasal serosa totalizing 18 animals submitted to the surgical treatment. Two animals were slaughtered and three cows arrived prostrated and died without receiving any treatment. Risk factor analysis identified rainy season as statistically significant. The greater number of abomasal displacement was in crossbred cows with 24 cases (66.6%, followed

    Our aim is to assess the safety and potential clinical benefit of intravenous iron (Ferinject) infusion in iron deficient patients with idiopathic pulmonary arterial hypertension (IPAH). Iron deficiency in the absence of anemia (1) is common in patients with IPAH; (2) is associated with inappropriately raised levels of hepcidin, the key regulator of iron homeostasis; and (3) correlates with disease severity and worse clinical outcomes. Oral iron absorption may be impeded by reduced absorption due to elevated hepcidin levels. The safety and benefits of parenteral iron replacement in IPAH are unknown. Supplementation of Iron in Pulmonary Hypertension (SIPHON) is a Phase II, multicenter, double-blind, randomized, placebo-controlled, crossover clinical trial of iron in IPAH. At least 60 patients will be randomized to intravenous ferric carboxymaltose (Ferinject) or saline placebo with a crossover point after 12 weeks of treatment. The primary outcome will be the change in resting pulmonary vascular resistance from baseline at 12 weeks, measured by cardiac catheterization. Secondary measures include resting and exercise hemodynamics and exercise performance from serial bicycle incremental and endurance cardiopulmonary exercise tests. Other secondary measurements include serum iron indices, 6-Minute Walk Distance, WHO functional class, quality of life score, N-terminal pro-brain natriuretic peptide (NT-proBNP), and cardiac anatomy and function from cardiac magnetic resonance. We propose that intravenous iron replacement will improve hemodynamics and clinical outcomes in IPAH. If the data supports a potentially useful therapeutic effect and suggest this drug is safe, the study will be used to power a Phase III study to address efficacy. PMID:23662181

    1994-05-01

    Since reported the design concept and system configuration of the McSPECT II last year, we have settled the design details and moved on to the construction phase. The major components being developed in this phase are: detector, collimator, electronics, interfaces, acquisition and processing software, and gantry systems. To provide adequate number of angular sampling (= views), we have increased the number of transverse detector elements to 120 NaI(Tl) bar-detectors in the new cylindrical detector system. These bar-detector are housed in 24 detector modules. Since we have developed a new light-guide and implemented a new 2-step centriod position calculation, the intrinsic performance of the detector modules has been substantially improved. These improvements lead to a simpler position estimation which yields < 4 mm FWHM spatial resolution in the 12 cm axial FOV. The imaging volume is 21 cm (dia.) x 12.8 (axial) cm. The number of collimator units (= rays) is increased to 100 to achieve high linear sampling density (2.3 mm) and sampling resolution ({approximately}5.6 mm). The collimator is still being manufacture. The electronics, acquisition, and processing systems are all in the final phases of debugging through simulated testing. The electronics is divided into 24 independent channels, one for each module. A 10-bit 1.0{mu}s ADC is connected to each of the 72 PMTs. A Pentium based PC performs real-time position calculation in 20 {mu}s/event. After de-randomizing, we expect 50 K/sec count-rate performance with little loss. Linearity and energy corrections are being implemented, in a separate calibration procedure, to yield <0.5 mm non-linearity and {approximately}10% energy resolution at 140 keV. The gantry construction is moving along well but slowly. The large (27.5 cm) aperture and the adjustable orientation of the gantry plane promise easy operation and patient comfort. The system construction should be completed soon to allow imaging studies to be performed.

  10. Sexual behaviour in cattle

    International Nuclear Information System (INIS)

    King, G.J.

    1990-01-01

    Short duration or weak expression of oestrus are frequently cited as major reasons for poor results when artificial insemination of Bos indicus breeds is attempted. The existing literature on sexual behaviour certainly indicates that oestrus sometimes lasts for only a few hours in Bos indicus, but similar patterns are also reported in Bos taurus animals. The period of sexual receptivity in suckled Hereford or Hereford-dairy cross-breds maintained in small, totally confined groups ranged from 1 to 18 h, with a mean of 4.4 h and a median of 3.5 h. In totally confined Holstein cows the onset of the LH surge always followed the beginning of homosexual activity by 1 or 2 h even when the period of receptivity was very short. Thus, the beginning rather than the end of oestrus should be used for estimating ovulation time. The expression of sexual behaviour is modified by many factors, including environmental conditions, the number of peri-oestrous females in the group and the presence of observers. In Hereford beef, Holstein dairy and probably all other cattle breeds, the variability in duration and intensity of oestrous activity is very large, so generalizations on a typical individual behavioural pattern are not possible.

    Full Text Available There is a little or no data available on the natural Babesia bovis (B. bovis infection in water buffaloes (Bubalus bubalis comparing to the available one for cattle. This study was conducted to investigate the natural B. bovis infection in water buffaloes in comparison to crossbred cattle under field conditions in Egypt.A total of 35 buffaloes and cattle were clinically and laboratory investigated from March to June 2008. Twenty-nine buffaloes and cattle out of 35 were naturally infected with B. bovis and showed signs of bovine babesiosis. Three cows and three buffaloes showed no clinical signs and were free from external, internal, and blood parasites served as control group.Babesia bovis-infected cattle showed typical signs of bovine babesiosis while B. bovis-infected buffaloes showed a milder form (less severe of the clinical signs. Advanced cases of cattle showed dark brown to dark red (coffee-color urine, hemoglobinuria and nervous manifestations while these manifestations were not detected in the infected buffaloes. Hematological changes in both species however, these changes were less significant in buffaloes than those reported in cattle.This paper documents the first description of natural B. bovis infection in water buffaloes which were found to be more likely to be tolerant than cattle to the natural clinical infection with B. bovis and its subsequent haematological changes. Our finding may lead to a better understanding of the disease pattern of B. bovis infection under field conditions in buffaloes.

    BRCA1/BRCA2 germ line (GL) mutation carriers with pancreatic adenocarcinoma (PDAC) may have distinct outcomes. We recently described an apparent more favourable prognosis of surgically resected BRCA-associated PDAC patients in a single-arm, uncontrolled, retrospective study. However, the prognostic impact of GL BRCA1/2 mutations in surgically resected PDAC has not been compared with a matched control population. A larger multi-centre, case-control retrospective analysis was performed. Cases were patients with surgically resected, BRCA1/2-associated PDAC from 2004 to 2013. Controls included surgically resected PDAC cases treated during the same time period that were either BRCA non-carriers, or had no family history of breast, ovarian or pancreatic cancers. Cases and controls were matched by: age at diagnosis (within ±5-year period) and institution. Demographics, clinical history, overall survival (OS) and disease-free survival (DFS) were abstracted from patient records. Statistical comparisons were assessed using χ 2 - and Fisher's exact test, and median DFS/OS using Kaplan-Meier method and log-rank testing. Twenty-five patients with BRCA1-(n=4) or BRCA2 (N=21)-associated resectable PDAC were identified. Mean age was 55.7 years (range, 34-78 years), 48% (n=12) were females and 76% (n=19) were Jewish. Cases were compared (1 : 2) with 49 resectable PDAC controls, and were balanced for age, ethnicity and other relevant clinical and pathological features. BRCA-associated PDAC patients received neoadjuvant, or adjuvant platinum-based treatment more frequently than controls (7 out of 8 vs 6 out of 14) and (7 out of 21 vs 3 out of 44), respectively. No significant difference in median OS (37.06 vs 38.77 months, P=0.838) and in DFS (14.3 vs 12.0 months, P=0.303) could be demonstrated between cases and controls. A trend to increased DFS was observed among BRCA-positive cases treated with neoadjuvant/adjuvant platinum-containing regimens (n=10) compared with similarly

    To investigate antibiotics prescribing patterns in the outpatient pediatric emergency clinic at Queen Rania Al Abdullah II Children's Hospital at Royal Medical Services in Amman, Jordan. The data was collected from the emergency pharmacy over the period of a -five consecutive months. The methodology recommended by the World Health Organization for investigating drug use in a health facility was followed. The study measures the percentage of encounter with a prescribed antibiotic and the percentage share of each antibiotic category. The distribution of diagnostic categories that accounted for all antibiotics being prescribed and the distribution of each antibiotic being prescribed for upper respiratory tract infections (URTIs) were also measured. Antibiotic prescribing was frequent during pediatric visits to the outpatient pediatric emergency clinic resulting in a high percentage of encounters (85%) when compared to appropriate. Emergency physicians continue to frequently prescribe broad spectrum antibiotics which accounted for approximately (60%) of the total prescribed antibiotics and (83%) of prescribed antibiotics for upper respiratory tract infections and macrolides (primarily azithromycin) were the leading class among them. Our results showed high consumption of antibiotics by emergency department pediatricians which highlight the importance for interventions to promote rational and judicious prescribing. An insight into factors influencing antibiotics prescribing patterns by military prescribers is required.

  16. Pediatric cancer gone viral. Part II: potential clinical application of oncolytic herpes simplex virus-1 in children

    Directory of Open Access Journals (Sweden)

    Gregory K Friedman

    Full Text Available Oncolytic engineered herpes simplex viruses (HSVs possess many biologic and functional attributes that support their use in clinical trials in children with solid tumors. Tumor cells, in an effort to escape regulatory mechanisms that would impair their growth and progression, have removed many mechanisms that would have protected them from virus infection and eventual virus-mediated destruction. Viruses engineered to exploit this weakness, like mutant HSV, can be safely employed as tumor cell killers, since normal cells retain these antiviral strategies. Many preclinical studies and early phase trials in adults demonstrated that oncolytic HSV can be safely used and are highly effective in killing tumor cells that comprise pediatric malignancies, without generating the toxic side effects of nondiscriminatory chemotherapy or radiation therapy. A variety of engineered viruses have been developed and tested in numerous preclinical models of pediatric cancers and initial trials in patients are underway. In Part II of this review series, we examine the preclinical evidence to support the further advancement of oncolytic HSV in the pediatric population. We discuss clinical advances made to date in this emerging era of oncolytic virotherapy.

    Sensitive, reliable measurement instruments are critical for the evaluation of disease progression and new treatments that affect the brain in the mucopolysaccharidoses (MPS). MPS I, II, and III have early onset clinical phenotypes that affect the brain during development and result in devastating cognitive decline and ultimately death without treatment. Comparisons of outcomes are hindered by diverse protocols and approaches to assessment including applicability to international trials necessary in rare diseases. We review both cognitive and adaptive measures with the goal of providing evidence to a Delphi panel to come to a consensus about recommendations for clinical trials for various age groups. The results of the consensus panel are reported in an accompanying article. The following data were gathered (from internet resources and from test manuals) for each measure and summarized in the discussion: reliability, validity, date and adequacy of normative data, applicability of the measure's metrics, cross cultural validity including translations and adaptations, feasibility in the MPS population, familiarity to sites, sensitivity to change, and interpretability. If, resulting from this consensus, standard protocols are used for both natural history and treatment studies, patients, their families, and health care providers will benefit from the ability to compare study outcomes.

    Ledipasvir/sofosbuvir combination treatment in phase III clinical trials resulted in sustained viral suppression in 94-99% of patients. This study characterized drug resistance in treatment failures, which may help to inform retreatment options. We performed NS5A and NS5B deep sequencing of hepatitis C virus (HCV) from patients infected with genotype (GT) 1 who participated in ledipasvir/sofosbuvir phase II and III clinical trials. Fifty-one of 2144 (2.4%) (42 GT1a and 9 GT1b) treated patients met the criteria for resistance analysis due to virologic failure following the end of treatment. The majority of patients with virologic failure (38 of 51; 74.5%) had detectable ledipasvir-specific resistance-associated substitutions (RASs) at the time of virologic failure (1% deep sequencing cut-off). The percent of patients with NS5A RASs at virologic failure were 37.5%, 66.7%, 94.7% and 100% in patients treated for 6, 8, 12 and 24weeks, respectively. The common substitutions detected at failure were Q30R/H, and/or Y93H/N in GT1a and Y93H in GT1b. At failure, 35.3% (18/51) of virologic failure patients' viruses had two or more NS5A RASs and the majority of patients harbored NS5A RASs conferring a 100-1000-fold (n=10) or >1000-fold (n=23) reduced susceptibility to ledipasvir. One patient in a phase II study with a known ledipasvir RAS at baseline (L31M) developed the S282T sofosbuvir (NS5B) RAS at failure. In GT1 HCV-infected patients treated with ledipasvir/sofosbuvir±ribavirin, virologic failure was rare. Ledipasvir resistance in NS5A was selected or enhanced in most patients with virologic failure, one of whom also developed resistance to sofosbuvir. Clinical studies have shown that combination treatment with ledipasvir/sofosbuvir efficiently cures most patients with genotype 1 hepatitis C infection. For the few patients failing treatment, we show that resistance to ledipasvir was observed in most patients, whereas resistance to sofosbuvir was less common. This has

Adicionalmente foram feitas observações sobre o diagnóstico do envenenamento crotálico e sua diferenciação com enfermidades que cursam com paralisia e necrose muscular em bovinos do Brasil.Crotalus poisoning was experimentally reproduced by subcutaneous inoculation of Crotalus durissus terrificus (South American rattlesnake venom into 10 clinically healthy mixed bred 12 to 36-month-old cattle, weighing 125 to 449 kg. Two animals were used as controls. The animal that received a dose of 0.03mg/kg body weight died 7h40min after inoculation. A 0.015mg/kg dose provoked death in 4 out of 7 young oxen. Two animals given 0.0075mg/kg became slightly sick and recovered. Onset of symptoms occurred from 1h30min to 13h45min after inoculation. The clinical course varied from 5h25min to 45h for animals that died, and from 33h15min to 17 days for animals that recovered. The main nervous signs observed were diminished response to external stimuli, hypotonic reflexes, dragging of the hooves, apathy, difficulties in moving around obstacles, ocular globe paralysis, lateral and sternal decubitus, and tongue paralysis. Adipsia and sometimes petechiae in the conjunctival and vaginal mucosa were observed. A slight to moderate increase in bleeding time was noted in 6 animals, and a moderate increase in partial thromboplastin time was found in 7 others. Moderate leukocytosis with neutrophilia, relative lymphopenia, eosinopenia, and monocytosis was found. There was a significant increase in creatine kinase serum levels of a ten-fold order. No significant alterations were revealed by urinalysis. Necropsy revealed minimal edema at the inoculation site, few petechiae and equimoses in the epicardium, omentum, biliary vesicle and bladder mucosa of some animals. Histopathological examination revealed necrosis (hyalinization of groups or isolated myocytes in different

    Full Text Available AIMS : To study the prevalence of the meibomian gland disease in typ e 2 diabetic patients and its clinical presentations. SETTING AND DESIGN : A hospital based cross sectional descriptive study of 100 type 2 diabetic patients attending a medical college was conducted. METHODS : Detailed diabetic history was recorded. Assessment of ocular surface i.e. the lid margins , conjunctiva , corneal surface was done via slit lamp biomicroscopy. Meibomian gland disease (MGD severity was assessed by the quality and expressibility of the meibomian secretion. Dry eye tests like schir mer’s test and tear film breakup time were done. STATISTICAL ANALYSIS USED : SPSS statistical software version 17 was used. RESULTS : 56% of the patients out of 100 diabetic patients had MGD. The most common symptom was burning (46.9% , followed by dryness ( 23.5% , 5.6% had conjunctival injection , 7.14% had corneal erosions , 25% had mucus debris , 53.65% had dry eye which was statistically significant (p=0.001 , 56.25% males and 72.2% females had the disease which was not statistically significant. CONCLUSION : The prevalence of Meibomian gland disease in the diabetic population was 56% which is more than the general population prevalence. Apart from other disorders diabetics are also more prone for ocular surface diseases like Meibomian gland disease. MGD is an important pre disposer for severe diseases like Dry eye in this subgroup of patients which can lead to complications like conjunctival keratinisations , corneal erosions and perforations. Careful examination of these patients for ocular surface disease and prompt treatment is required.

    Background This study describes the relationship of irritable mood (IRR) with affective disorders in youths with attention deficit hyperactivity disorder (ADHD). Methods Five hundred ADHD subjects were assessed with the childhood version of the Schedule for Affective Disorder & Schizophrenia. Subjects were in a genetic ADHD protocol and limited to those of Caucasian/European descent. Results The most prevalent concurrent diagnoses were oppositional defiant disorder (ODD) (43.6%), minor depression/dysthymic disorder (MDDD) (18.8%), and generalized anxiety (13.2%)/overanxious disorder (12.4%). IRR subjects (21.0%) compared to the non-IRR (NIRR) group had higher rates of all affective disorders (76.2% vs. 9.6%) and ODD (83.8% vs. 32.9%) but lower rates of hyperactive ADHD (1.9% vs. 8.9%). Among those without comorbidities, 98.3% were NIRR. Logistic regression found IRR mood significantly associated with major depressive disorder (odds ratio [OR]: 33.4), MDDD (OR: 11.2), ODD (OR: 11.6), and combined ADHD (OR: 1.7) but not with anxiety disorders. Among symptoms, it associated IRR mood with a pattern of dysthymic and ODD symptoms but with fewer separation anxiety symptoms. Diagnostic and symptomatic parameters were unaffected by demographic variables. Limitations Potential confounders influencing these results include patient recruitment from only one clinical service; a cohort specific sample effect because some presumed affective disorders and non-Caucasians were excluded; and the young mean age (10.2 years) limiting comorbid patterns. Conclusions The prominence of an MDDD pattern suggests this IRR group is appropriate in the DSM V's proposed chronic depressive disorder, possibly with or without temper dysregulation. A new diagnosis of disruptive mood dysregulation disorder may be unwarranted. PMID:22868057

    Cattle domestication started in the 9(th) millennium BC in Southwest Asia. Domesticated cattle were then introduced into Europe during the Neolithic transition. However, the scarcity of palaeogenetic data from the first European domesticated cattle still inhibits the accurate reconstruction of their early demography. In this study, mitochondrial DNA from 193 ancient and 597 modern domesticated cattle (Bos taurus) from sites across Europe, Western Anatolia and Iran were analysed to provide insight into the Neolithic dispersal process and the role of the local European aurochs population during cattle domestication. Using descriptive summary statistics and serial coalescent simulations paired with approximate Bayesian computation we find: (i) decreasing genetic diversity in a southeast to northwest direction, (ii) strong correlation of genetic and geographical distances, iii) an estimated effective size of the Near Eastern female founder population of 81, iv) that the expansion of cattle from the Near East and Anatolia into Europe does not appear to constitute a significant bottleneck, and that v) there is evidence for gene-flow between the Near Eastern/Anatolian and European cattle populations in the early phases of the European Neolithic, but that it is restricted after 5,000 BCE. The most plausible scenario to explain these results is a single and regionally restricted domestication process of cattle in the Near East with subsequent migration into Europe during the Neolithic transition without significant maternal interbreeding with the endogenous wild stock. Evidence for gene-flow between cattle populations from Southwestern Asia and Europe during the earlier phases of the European Neolithic points towards intercontinental trade connections between Neolithic farmers.

  5. Clinical impact of the temporal relationship between depression and type 2 diabetes: the Fremantle diabetes study phase II.

    Full Text Available BACKGROUND: The clinical features of type 2 diabetes may differ depending on whether first depression episode precedes or follows the diagnosis of diabetes. METHODS: Type 2 patients from the observational community-based Fremantle Diabetes Study Phase II underwent assessment of lifetime depression using the Brief Lifetime Depression Scale (developed and validated for this study supplemented by information on current depression symptoms (Patient Health Questionnaire, 9-item version and use of antidepressants. Patients were categorized as never depressed (Group 1, having had depression before diabetes diagnosis (Group 2, diagnosed with depression and diabetes within 2 years of each other (Group 3 and having depression after diabetes diagnosis (Group 4. RESULTS: Of 1391 patients, 20.8% were assigned to Group 2, 6.0% to Group 3 and 14.5% to Group 4. In Group 2, depression occurred a median 15.6 years before diabetes onset at age 37.2±14.7 years. These patients had similar clinical characteristics to never depressed patients except for reduced self-care behaviours and having more symptomatic peripheral arterial disease. In Group 4, depression occurred a median 9.9 years after diabetes onset at age 59.8±13.0 years. These patients had long duration diabetes, poor glycaemic control, more intensive management and more diabetic complications. Group 4 patients had more current depression than Group 2 but were less likely to be receiving antidepressants. CONCLUSIONS/INTERPRETATION: The clinical features of depression and type 2 diabetes are heterogeneous depending on their temporal relationship. There may be corresponding differences in the pathogenesis of depression in diabetes that have implications for diagnosis and management.

    To describe a simple technical evaluation of the access, security issues and uses of wireless networked PDAs in a dental clinic and report a pilot study investigating students' educational use of PDAs to access a Virtual Learning Environment (VLE) in a dental clinic. To undertake a technical evaluation of wireless networking to PDAs focusing on security issues, robustness of the system and accessibility particularly to educational resources. To evaluate the impact of using a PDA on undergraduate students in the dental clinic and at home. Part II describes the technical and educational evaluation of PDAs used by one group of 12 undergraduate fourth year students in the Primary Dental Care clinic. A cross over trial of six students with PDAs and six without was carried out during one semester of 12 weeks. Technical issues such as secure internet access using wireless connectivity were addressed. An assessment of the general and educational use and the students' attitudes towards using PDAs was undertaken using online questionnaires and focus group discussions. Over 90% of participants wanted PDAs as part of their dental kit. The potential of PDA use in dental training was demonstrated by a good to excellent response by over 75% of participants to having access to online support materials, particularly videos, being able to make notes for individual study and to keep a diary of their commitments to teaching sessions. Recreational use included a 100% good to excellent response to playing games and keeping a diary. The PDA proved to be a convenient and versatile mode of access to online education. Technical solutions enabled a substantial proportion of the functionality of WebCT (Web Course Tools) to be accessed by the students in a clinical environment. Both novice and experienced users were able to appreciate the use of the PDA and the less able considered that their ICT skills had improved. However, further research is needed to determine how students use a range of

    In the world, Kalanchoe species are primarily ornamentals and houseplants, but some have escaped cultivation and can be found in the field. In Latin America, there are no reports of spontaneous poisoning by Kalanchoe species in animals. This study aimed to describe the epidemiological, clinical, and pathological aspects of an outbreak of poisoning by Kalanchoe blossfeldiana in cattle in the semiarid region of Pernambuco, Brazil. Epidemiological and clinical data were obtained from the owner and veterinarian during technical visits. Prunings of this plant were disposed of in a pasture with a shortness of forage. Seventeen cattle had clinical signs, and thirteen died 4-5 days after the first clinical signs were observed. Clinical signs and gross and histological lesions include gastrointestinal, cardiovascular, and neuromuscular disorders. Kalanchoe spp. contain cardiotoxic glycosides, and the clinical signs and lesions in cattle of this outbreak were consistent with poisoning by plants that contain these toxins.

  8. Molecular diagnosis and phylogenetic analysis of Babesia bigemina and Babesia bovis hemoparasites from cattle in South Africa

    2013-01-01

    Background Babesia parasites, mainly Babesia bovis and B. bigemina, are tick-borne hemoparasites inducing bovine babesiosis in cattle globally. The clinical signs of the disease include, among others, anemia, fever and hemoglobinuria. Babesiosis is known to occur in tropical and subtropical regions of the world. In this study, we aim to provide information about the occurrence and phylogenetic relationship of B. bigemina and B. bovis species in cattle from different locations in nine provinces of South Africa. A total of 430 blood samples were randomly collected from apparently healthy cattle. These samples were genetically tested for Babesia parasitic infections using nested PCR assays with species-specific primers. Results Nested PCR assays with Group I primer sets revealed that the overall prevalence of B. bigemina and B. bovis in all bovine samples tested was 64.7% (95% CI = 60.0-69.0) and 35.1% (95% CI = 30.6-39.8), respectively. Only 117/430 (27.2%) animals had a mixed infection. The highest prevalence of 87.5% (95% CI = 77.2-93.5) for B. bigemina was recorded in the Free State province collection sites (Ficksburg, Philippolis and Botshabelo), while North West collection sites had the highest number of animals infected with B. bovis (65.5%; 95% CI = 52.7-76.4). Phylograms were inferred based on B. bigemina-specific gp45 and B. bovis-specific rap-1 nucleotide sequences obtained with Group II nested PCR primers. Phylogenetic analysis of gp45 sequences revealed significant differences in the genotypes of B. bigemina isolates investigated, including those of strains published in GenBank. On the other hand, a phylogeny based on B. bovis rap-1 sequences indicated a similar trend of clustering among the sequences of B. bovis isolates investigated in this study. Conclusion This study demonstrates the occurrence of Babesia parasites in cattle from different provinces of South Africa. It was also noted that the situation of Babesia parasitic infection

    To investigate the safety and effects of intravitreal sirolimus for the potential treatment of geographic atrophy (GA). The study was a single-center, open-label, phase I/II trial enrolling six participants with bilateral GA treated with intravitreal sirolimus in only one randomly assigned eye, with the fellow eye as control. The primary efficacy outcome measure was the change in total GA area from baseline on color fundus photography (CFP); secondary outcomes included changes in GA area on fundus autofluorescence (FAF), visual acuity, central retinal thickness (CRT), and macular sensitivity from baseline. Although no systemic adverse events were attributed to treatment, two of six participants had ocular adverse events that were possibly associated. The treated eye of one participant developed abnormal paralesional changes on FAF that were associated with accelerated retinal thinning. This accelerated retinal thinning was also seen in the treated eye of a second participant. Because of concern that these events were associated with treatment, treatment was suspended. Comparisons of treated and fellow eyes for change in visual acuity, change in GA area, and change in CRT showed no evidence of treatment benefit and generally favored the untreated fellow eye. While paralesional FAF changes and rapid retinal thinning observed are potentially part of the natural course of GA, they may possibly be related to treatment. No general evidence of anatomical or functional benefit was detected in treated eyes. Further data on intravitreal sirolimus for GA treatment will be available from a larger phase II trial.

    Full Text Available Angiotensin II (Ang II receptor blockers are the newest class of antihypertensive drugs to be developed. No large-scale clinical trials have been performed to evaluate their efficacy alone, or in combination with other drugs. A large-scale, eight week, open-label, non-placebo-controlled, single-arm trial evaluated the efficacy, tolerability and dose-response of candesartan cilexetil, 16—32 mg once-daily, either as monotherapy or as part of combination therapy, in a diverse hypertensive population in actual practice settings. 6465 patients with high blood pressure, of whom 52% were female and 16% African American, with a mean age of 58 years, were included. 5446 patients had essential hypertension and 1014 patients had isolated systolic hypertension. In order to be included in this study, patients had either untreated or uncontrolled hypertension (systolic blood pressure (SBP 140—179 mmHg and/or diastolic blood pressure (DBP 90—109 mmHg inclusive at baseline, despite a variety of other antihypertensive drugs. Of the 5156 patients with essential hypertension and at least one post baseline efficacy measurement, the mean pretreatment blood pressure (BP was 156/97 mmHg. Candesartan cilexetil monotherapy reduced mean SBP/DBP by 18.0/12.2 mmHg. Similarly, in the 964 patients with isolated systolic hypertension and at least one post baseline efficacy measurement, candesartan cilexetil monotherapy reduced SBP/DBP from 158/81 by 16.5/4.5 mmHg. Candesartan cilexetil was similarly effective when employed as add-on therapy. When added to baseline antihypertensive medication in 51% of the patients with essential hypertension not achieving BP control, additional reduction in BP was achieved regardless of the background therapy, including diuretics (17.8/11.7 mmHg calcium antagonists (16.6/11.2 mmHg, beta-blockers (16.5/10.4 mmHg, angiotensin-converting enzyme inhibitors (ACE-I (15.3/10.0 mmHg, and alpha blockers (16.4/10.4 mmHg.

    Rift Valley fever (RVF) is a vector-borne disease affecting ruminants and humans. Madagascar was heavily affected by RVF in 2008-2009, with evidence of a large and heterogeneous spread of the disease. The identification of at-risk environments is essential to optimize the available resources by targeting RVF surveillance in Madagascar. Herein, the objectives of our study were: (i) to identify the environmental factors and areas favorable to RVF transmission to both cattle and human and (ii) to identify human behaviors favoring human infections in Malagasy contexts. First, we characterized the environments of Malagasy communes using a Multiple Factor Analysis (MFA). Then, we analyzed cattle and human serological data collected at national level using Generalized Linear Mixed Models, with the individual serological status (cattle or human) as the response, and MFA factors, as well as other potential risk factors (cattle density, human behavior) as explanatory variables. Cattle and human seroprevalence rates were positively associated to humid environments (p<0.001). Areas with high cattle density were at risk (p<0.01; OR = 2.6). Furthermore, our analysis showed that frequent contact with raw milk contributed to explain human infection (OR = 1.6). Finally, our study highlighted the eastern-coast, western and north-western parts as high-risk areas for RVF transmission in cattle. Our integrated approach analyzing environmental, cattle and human datasets allow us to bring new insight on RVF transmission patterns in Madagascar. The association between cattle seroprevalence, humid environments and high cattle density suggests that concomitant vectorial and direct transmissions are critical to maintain RVF enzootic transmission. Additionally, in the at-risk humid environment of the western, north-western and the eastern-coast areas, suitable to Culex and Anopheles mosquitoes, vectorial transmission probably occurs in both cattle and human.

    Laminitis is regarded as a major predisposing factor in lameness caused by claw disorders. Despite intensive study, both by experiment and by clinical observation, knowledge of the precise aetiology and pathogenesis of bovine laminitis is still incomplete. It is often hypothesized that changes in the micro-circulation of the corum (dermis) of the bovine claw contribute significantly to the development of laminitis; arteriovenous anastomoses (AVAs) playing a crucial role. Many factors have been implicated as contributing causes of laminitis in cattle; the disease has a multifactorial aetiology. The cause of laminitis should be considered as a combination of predisposing factors leading to vascular (AVAs in particular) reactivity and inhibition of normal horn synthesis. Nutrition, disease, management and behaviour appear to be closely involved in the pathogenesis of bovine laminitis. The major factors predisposing to laminitis in cattle, as reported or suggested in the literature, are reviewed, including systemic disease, nutrition (barley grain, protein, carbohydrate and fibre), management (housing, bedding and exercise), calving, season, age, growth, genetics, conformation and behaviour.

    The potential application of radioisotopes are not discussed in this review of trypanosome pathogenesis in cattle. Initially, structural changes in the lymphoid system are characterized by marked proliferation and germinal centre formation, whereas in long-standing infections the lymphoid organs become depleted. These changes appear associated with immunodepression. Anaemia dominates the clinical disease syndrome in bovine trypanosomiasis. It develops with the onset of parasitaemia and is largely haemolytic, resulting from increased red blood cell destruction by phagocytosis. Several factors may be involved in this process including haemolysins produced by the trypanosome, immunological mechanisms, fever, disseminated intravascular coagulation and an expanded and active mononuclear phagocytic system. During this phase of the disease, cattle respond well to chemotherapy. However, in later phases of the disease, when trypanosomes cannot be detected, the anaemia sometimes persists and animals do not respond to treatment. Concerning the underlying mechanisms responsible for the anaemia, continued red cell destruction combined with some dyshaemopoiesis, associated with a defect in iron metabolism, appears responsible. Widespread tissue degeneration occurs. Organs particularly severely affected include the heart. Death in bovine trypanosomiasis is presumably due to a combination of anaemia, microcirculatory disturbances and myocardial damage. The factors incriminated in tissue damage probably vary with the species of trypanosome involved, although under natural field conditions it is common to find T. congolense, T. vivax and T. brucei in one animal. Likely pathogenic mechanisms in bovine include anoxia as a result of anaemia, microcirculatory disorders and hypersensitivity reactions

    2009-11-01

    Full Text Available Abstract Background Loeys-Dietz syndrome (LDS is a rare autosomal dominant disorder showing the involvement of cutaneous, cardiovascular, craniofacial, and skeletal systems. In particular, LDS patients show arterial tortuosity with widespread vascular aneurysm and dissection, and have a high risk of aortic dissection or rupture at an early age and at aortic diameters that ordinarily are not predictive of these events. Recently, LDS has been subdivided in LDS type I (LDSI and type II (LDSII on the basis of the presence or the absence of cranio-facial involvement, respectively. Furthermore, LDSII patients display at least two of the major signs of vascular Ehlers-Danlos syndrome. LDS is caused by mutations in the transforming growth factor (TGF beta-receptor I (TGFBR1 and II (TGFBR2 genes. The aim of this study was the clinical and molecular characterization of two LDS patients. Methods The exons and intronic flanking regions of TGFBR1 and TGFBR2 genes were amplified and sequence analysis was performed. Results Patient 1 was a boy showing dysmorphic signs, blue sclerae, high-arched palate, bifid uvula; skeletal system involvement, joint hypermobility, velvety and translucent skin, aortic root dilatation, tortuosity and elongation of the carotid arteries. These signs are consistent with an LDSI phenotype. The sequencing analysis disclosed the novel TGFBR1 p.Asp351Gly de novo mutation falling in the kinase domain of the receptor. Patient 2 was an adult woman showing ascending aorta aneurysm, with vascular complications following surgery intervention. Velvety and translucent skin, venous varicosities and wrist dislocation were present. These signs are consistent with an LDSII phenotype. In this patient and in her daughter, TGFBR2 genotyping disclosed in the kinase domain of the protein the novel p.Ile510Ser missense mutation. Conclusion We report two novel mutations in the TGFBR1 and TGFBR2 genes in two patients affected with LDS and showing marked

    Full Text Available ABSTRACT: Bovine vaccinia (BV is a vesicular disease induced by the Vaccinia virus (VACV that affects milk production and is an occupational zoonosis. This research had the following objectives: (i detection of VACV by qPCR in cattle with clinical suspicion of vesicular disease; (ii symptoms characterization in animals and milkers with clinical suspicion of the disease and virus detection in humans; and (iii identification of risk factors for infections of VACV in herds from several Brazilian states. A total of 471 bovine epithelial samples from dairy farms, in 15 Brazilian states, were evaluated between 2007 and 2012. The samples were tested by quantitative PCR (qPCR using SYBR Green® reagents, validated with a lower limit of detection of 100 TCID50/50µL (1.7x100 viral particles, and 45.1% of VACV positive samples were detected. Using official forms for epidemiological investigation (FORM-IN, the risk factors for VACV infections in cattle were determined to be farms with a lack of technological facilities (P=0.029 and the presence of rodents (P=0.001. There was an effect of seasonality in cattle with a higher occurrence of BV during the dry season. A total of 420 epidemiological questionnaires were applied at public health care centers, where 100% of the milkers had vesicular lesions on their hands (98.1% and on their arms (6.9%. The most frequent clinical symptoms in humans were: local swelling (74.2%, headache (20.7%, fever (10.4% and inguinal lymphadenopathy (74.2%. Only 19.98% of milkers aged between 39 and 58 years were seroreactive to VACV and were immunized with the human anti-smallpox vaccine. There was an increase in the frequency of BV in older individuals due to their natural decrease in specific immunity. It has been shown that the implementation of zootechnical management techniques and health planning are important for the prevention of BV in animals and humans.

    Livestock production is a major sector of the Ugandan economy. Ugandan ruminant livestock (principally cattle and goats) are susceptible to hemoparasites that can cause serious clinical disease and production losses. Kibale National Park, in western Uganda, is a protected forest ecosystem surrounded by small-scale farms where cattle and goats are raised. We conducted a cross-sectional study of cattle and goats in this area and diagnosed hemoparasite infections by microscopy. We collected data on animal characteristics and management practices to assess risk factors associated with infection. We studied 186 cattle and 317 goats from 20 villages, including 16 villages directly adjacent to Kibale and 4 villages ≥3 km from the park boundary. Hemoparasites detected in cattle and goats were of the genera Theileria, Anaplasma, and Trypanosoma with a prevalence of 15.1%, 1.6%, and 4.3% respectively in cattle, and 10%, 6.0%, and 0.0%, respectively in goats. Trypanosomes infected approximately 8% of cattle in villages bordering Kibale but were never detected in cattle in "control" villages ≥3 km from the park. Trypanosomes were approximately 7 times more likely to infect animals in households that did not provide veterinary care to their animals than in households that provided routine veterinary care. Within cattle, Theileria infections were approximately 7 times more likely to occur in cross-bred cattle than in indigenous pure breeds. Anaplasma infections were approximately 3.5 times more likely to occur in cattle than in goats (no goats were diagnosed with Trypanosoma infection). These data suggest that proximity to the park, provision of veterinary care, and breed are significant risk factors for hemoparasites in this population of ruminants, and that, in general, cattle are more susceptible than goats.

    The aim of this study was to determine whether the practice of co-grazing with cattle and wild life constitutes a risk of transmission of antibiotic resistant bacteria to wild ungulates. Faecal samples were collected from buffalo (n = 35), wildebeest (n = 40), zebra (n = 40) and cattle (N = 20) from Mikumi National Park, Tanzania (MNP), where cattle is prohibited and from Ngorongoro Conservation Area (NCA) where co-grazing is practiced. The number of coliforms and enterococci resistant to selected antibiotics was determined. Wild life generally harboured higher number of resistant Escherichia coli and Enterococci than cattle, but with no general influence in wild life of co-grazing with cattle. Vancomycin-resistant Enterococci were detected in wild life samples, and E. coli resistant to cefotaxime and enrofloxacin were observed among isolates from all wild life, but not from cattle. Culture independent estimates of the number of sulII gene copies obtained by qPCR did not differ between wild life from the two sample sites, while tetW was significantly higher in samples from MPN than from NCA. Antibiotic resistant bacteria were not more frequently found in ungulates grazing together with cattle than ungulates without this interaction. This study did not indicate that transmission of antibiotic resistant bacteria is a frequent event following co-grazing of wild life and cattle. © 2014 The Society for Applied Microbiology.

    Plasmodium knowlesi is one of the monkey malaria parasites that can cause human malaria. The Duffy binding protein of P. knowlesi (PkDBPαII) is essential for the parasite's invasion into human and monkey erythrocytes. A previous study on P. knowlesi clinical isolates from Peninsular Malaysia reported high level of genetic diversity in the PkDBPαII. Furthermore, 36 amino acid haplotypes were identified and these haplotypes could be separated into allele group I and allele group II. In the present study, the PkDBPαII of clinical isolates from the Malaysian states of Sarawak and Sabah in North Borneo was investigated, and compared with the PkDBPαII of Peninsular Malaysia isolates. Blood samples from 28 knowlesi malaria patients were used. These samples were collected between 2011 and 2013 from hospitals in North Borneo. The PkDBPαII region of the isolates was amplified by PCR, cloned into Escherichia coli, and sequenced. The genetic diversity, natural selection and phylogenetics of PkDBPαII haplotypes were analysed using MEGA5 and DnaSP ver. 5.10.00 programmes. Forty-nine PkDBPαII sequences were obtained. Comparison at the nucleotide level against P. knowlesi strain H as reference sequence revealed 58 synonymous and 102 non-synonymous mutations. Analysis on these mutations showed that PkDBPαII was under purifying (negative) selection. At the amino acid level, 38 different PkDBPαII haplotypes were identified. Twelve of the 28 blood samples had mixed haplotype infections. Phylogenetic analysis revealed that all the haplotypes were in allele group I, but they formed a sub-group that was distinct from those of Peninsular Malaysia. Wright's FST fixation index indicated high genetic differentiation between the North Borneo and Peninsular Malaysia haplotypes. This study is the first to report the genetic diversity and natural selection of PkDBPαII of P. knowlesi from Borneo Island. The PkDBPαII haplotypes found in this study were distinct from those from

    Inflammation contributes significantly to the pathogenesis of diabetic macular edema (DME). In particular, retinal microglia demonstrate increased activation and aggregation in areas of DME. Study authors investigated the safety and potential efficacy of oral minocycline, a drug capable of inhibiting microglial activation, in the treatment of DME. A single-center, prospective, open-label phase I/II clinical trial enrolled five participants with fovea-involving DME who received oral minocycline 100 mg twice daily for 6 months. Main outcome measurements included best-corrected visual acuity (BCVA), central retinal subfield thickness (CST), and central macular volume using spectral domain optical coherence tomography (SD-OCT) and late leakage on fluorescein angiography (FA). Findings indicated that the study drug was well tolerated and not associated with significant safety issues. In study eyes, mean BCVA improved continuously from baseline at 1, 2, 4, and 6 months by +1.0, +4.0, +4.0, and +5.8 letters, respectively, while mean retinal thickness (CST) on OCT decreased by -2.9%, -5.7%, -13.9, and -8.1% for the same time points. At month 6, mean area of late leakage on FA decreased by -34.4% in study eyes. Mean changes in contralateral fellow eyes also demonstrated similar trends. Improvements in outcome measures were not correlated with concurrent changes in systemic factors. In this pilot proof-of-concept study of DME, minocycline as primary treatment was associated with improved visual function, central macular edema, and vascular leakage, comparing favorably with historical controls from previous studies. Microglial inhibition with oral minocycline may be a promising therapeutic strategy targeting the inflammatory etiology of DME. (ClinicalTrials.gov number, NCT01120899.).

    Cattle are bred for, amongst other factors, specific traits, including parasite resistance and adaptation to climate. However, the influence and inheritance of mitochondrial DNA (mtDNA) are not usually considered in breeding programmes. In this study, we analysed the mtDNA profiles of cattle from Victoria (VIC), southern Australia, which is a temperate climate, and the Northern Territory (NT), the northern part of Australia, which has a tropical climate, to determine if the mtDNA profiles of these cattle are indicative of breed and phenotype, and whether these profiles are appropriate for their environments. A phylogenetic tree of the full mtDNA sequences of different breeds of cattle, which were obtained from the NCBI database, showed that the mtDNA profiles of cattle do not always reflect their phenotype as some cattle with Bos taurus phenotypes had Bos indicus mtDNA, whilst some cattle with Bos indicus phenotypes had Bos taurus mtDNA. Using D-loop sequencing, we were able to contrast the phenotypes and mtDNA profiles from different species of cattle from the 2 distinct cattle breeding regions of Australia. We found that 67 of the 121 cattle with Bos indicus phenotypes from NT (55.4%) had Bos taurus mtDNA. In VIC, 92 of the 225 cattle with Bos taurus phenotypes (40.9%) possessed Bos indicus mtDNA. When focusing on oocytes from cattle with the Bos taurus phenotype in VIC, their respective oocytes with Bos indicus mtDNA had significantly lower levels of mtDNA copy number compared with oocytes possessing Bos taurus mtDNA (P cattle with a Bos taurus phenotype. The phenotype of cattle is not always related to their mtDNA profiles. MtDNA profiles should be considered for breeding programmes as they also influence phenotypic traits and reproductive capacity in terms of oocyte quality.

    To explore the readability and content integrity of informed consent forms (ICFs) used in China and to compare the quality of Chinese local ICFs with that of international ICFs. The length, readability and content of 155 consent documents from phase II-IV drug clinical trials from the Third Xiangya Hospital Ethics Committee from November 2009 to January 2015 were evaluated. Reading difficulty was tested using a readability formula adapted for the Chinese language. An ICF checklist containing 27 required elements was successfully constructed to evaluate content integrity. The description of alternatives to participation was assessed. The quality of ICFs from different sponsorships were also compared. Among the 155 evaluable trials, the ICFs had a median length of 5286 words, corresponding to 7 pages. The median readability score was 4.31 (4.02-4.41), with 63.9% at the 2nd level and 36.1% at the 3rd level. Five of the 27 elements were frequently neglected. The average score for the description of alternatives to participation was 1.06, and 27.7% of the ICFs did not mention any alternatives. Compared with Chinese local ICFs, international ICFs were longer, more readable and contained more of the required elements (P readability and content integrity than Chinese local ICFs. More efforts should thus be made to improve the quality of consent documents in China.

    To evaluate the safety and preliminary efficacy of intravitreal ranibizumab for nonneovascular idiopathic macular telangiectasia Type 2. Single-center, open-label Phase II clinical trial enrolling five participants with bilateral nonneovascular idiopathic macular telangiectasia Type 2. Intravitreal ranibizumab (0.5 mg) was administered every 4 weeks in the study eye for 12 months with the contralateral eye observed. Outcome measures included changes in best-corrected visual acuity, area of late-phase leakage on fluorescein angiography, and retinal thickness on optical coherence tomography. The study treatment was well tolerated and associated with few adverse events. Change in best-corrected visual acuity at 12 months was not significantly different between treated study eyes (0.0 ± 7.5 letters) and control fellow eyes (+2.2 ± 1.9 letters). However, decreases in the area of late-phase fluorescein angiography leakage (-33 ± 20% for study eyes, +1 ± 8% for fellow eyes) and in optical coherence tomography central subfield retinal thickness (-11.7 ± 7.0% for study eyes and -2.9 ± 3.5% for fellow eyes) were greater in study eyes compared with fellow eyes. Despite significant anatomical responses to treatment, functional improvement in visual acuity was not detected. Intravitreal ranibizumab administered monthly over a time course of 12 months is unlikely to provide a general and significant benefit to patients with nonneovascular idiopathic macular telangiectasia Type 2.

Intravitreal ranibizumab (0.5mg) was administered every 4 weeks in the study eye for 12 months with the contralateral eye observed. Outcome measures included changes in: best corrected visual acuity (BCVA), area of late-phase leakage on fluorescein angiography (FA), and retinal thickness on optical coherence tomography (OCT). Results The study treatment was well-tolerated and associated with few adverse events. Change in BCVA at 12 months was not significantly different between treated study eyes (0.0±7.5 letters) and control fellow eyes (+2.2±1.9 letters). However, decreases in the area of late-phase FA leakage (−33±20% for study eyes, +1±8% for fellow eyes) and in OCT central subfield retinal thickness (−11.7±7.0% for study eyes and −2.9±3.5% for fellow eyes) were greater in study eyes compared to fellow eyes. Conclusions Despite significant anatomical responses to treatment, functional improvement in visual acuity was not detected. Intravitreal ranibizumab administered monthly over a time course of 12 months is unlikely to provide a general and significant benefit to patients with non-neovascular IMT2. PMID:22266930

    Molecular targeting may be defined as the specific concentration of a diagnostic or therapeutic tracer by its interaction with a molecular species that is distinctly present or absent in a disease state. Monoclonal antibody (mAb) is one of the successful agents for targeted therapy in cancer. To enhance the therapeutic effect. the concept of targeting radionuclides to tumors using radiolabeled mAbs against tumor-associated antigens, radioimmunotherapy, was proposed. The efficacy of radioimmunotherapy, however, has to be further optimized. Several strategies to improve targeting of tumors with radiolabeled mAbs have been developed, such as the use of mAb fragments, the use of high-affinity mAbs, the use of labeling techniques that are stable in vivo, active removal of the radiolabeled mAb from the circulation, and pretargeting strategies. Until now, however, there are many kinds of obstacles to be solved in the use of mAb for the targeted therapy. Major technical challenges to molecular targeting are related to the rapid and specific delivery of tracers to the target, the elimination of unwanted background activity, and the development of more specific targets to create a cytocidal effect. Further development of this field will be determined by success in solving these challenges

    Bovine herpes virus 1 (BHV-1) is primarily associated with clinical syndromes such as rhinotracheitis, pustular vulvovaginitis and balanoposthitis, abortion, infertility, conjunctivitis and encephalitis in bovine species. The main sources of infection are the nasal exudates and the respiratory droplets, genital secretions, semen, fetal fluids and tissues. The BHV-1 virus can become latent following a primary infection with a field isolate or vaccination with an attenuated strain. The viral genomic DNA has been demonstrated in the sensory ganglia of the trigeminal nerve in infectious bovine rhinotracheitis (IBR) and in sacral spinal ganglia in pustular vulvovaginitis and balanoposthitis cases. BHV-1 infections can be diagnosed by detection of virus or virus components and antibody by serological tests or by detection of genomic DNA by polymerase chain reaction (PCR), nucleic acid hybridization and sequencing. Inactivated vaccines and modified live virus vaccines are used for prevention of BHV-1 infections in cattle; subunit vaccines and marker vaccines are under investigation.

    Objective: To investigate the clinical significance of changes of plasma ET, IGF-II, CNP and serum NSE contents in patients with acute brain injury. Methods: Serum contents of neuron specific enolase (NSE) were measured with chemiluminescence immunoassay and plasma endothelin (ET), insulin-like growth factor-II (IGF-II) and C-type natriuretic peptide (CNP) were measured with radioimmunoassay in 30 patients with acute brain injury and 35 controls. Results: Serum contents of NSE and plasma IGF-II, CNP were not much different in patients with mild brain injury from those in controls (P >0.05), but plasma contents of ET were already significantly higher in patients with mild brain injury than those in controls(P < 0.01). The serum NSE and plasma ET levels in patients with moderate and severe brain injury were significantly higher than those in patients with mild brain injury and controls (P < 0.01). Decrease of plasma levels of IGF-II and CNP was not significant in patients with mild brain injury (vs controls). However, the plasma levels of IGF-II and CNP were significantly lower in patients with moderate and severe brain injury than those in patients with mild brain injury and controls (P <0.01). As a whole, the magnitude of changes of these parameters was proportional to the severity of the injury. Conclusion: Changes of serum NSE and plasma IGF-II, ET and CNP levels were closely related to the pathological process of brain injury. Determination of these parameters was of clinical importance for evaluation of the severity of injury and outcome prediction. (authors)

    With the publication of DSM 5 alternative model for personality disorders it is critical to assess the components of the model against evidence-based models such as the five factor model and the DSM-IV-TR categorical model. This study explored the relative clinical utility of these models in screening for borderline personality disorder (BPD). Receiver operator characteristics and diagnostic efficiency statistics were calculated for three personality measures to ascertain the relative diagnostic efficiency of each measure. A total of 1653 adult inpatients at a specialist psychiatric hospital completed SCID-II interviews. Sample 1 (n=653) completed the SCID-II interviews, SCID-II Questionnaire (SCID-II-PQ) and the Big Five Inventory (BFI), while Sample 2 (n=1,000) completed the SCID-II interviews, Personality Inventory for DSM5 (PID-5) and the BFI. BFI measure evidenced moderate accuracy for two composites: High Neuroticism+ low agreeableness composite (AUC=0.72, SE=0.01, ptrait constellation for diagnosing BPD. Limitations of the study include the single inpatient setting and use of two discrete samples to assess PID-5 and SCID-II-PQ. Copyright © 2017 Elsevier Inc. All rights reserved.

    Full Text Available The diet of high-yield dairy cows process a very complex and acute problem. Much new knowledge in the area of production and preparation of feedstuffs, diet technology, and the interactions that occur between the components of the nutritive feed ration are required in order to resolve this problem. It is necessary constantly to coordinate feed norms with genetic potential which is ever changing and advanced. The observed problems must be resolved using multidisciplinary methods so that a diet can yield good health, and that health contribute to better reproduction and possibilities for more successful breeding and improved performance in cattle farming. In certain countries, thanks to their geographic position and climatic conditions which allow rainfall throughout the year, a natural green diet can be applied, which provides large numbers of green mass components, and with additives which can be supplemented relatively easily. This type of diet is not possible in our farms. It is very important to know which feedstuff components are laking for certain categories of cattle. The used ration must be constant and administered to animals of certain age or production characteristics in order to improve production results at cattle farms. A great problem occurs when diet is reduced due to dried grass and the resulting stress in animals. A 50% diet reduction in young cattle often results in the occurrence of respiratory diseases. Following 10-14 days of treatment, the disease disappears in young animals, but the energy deficit leads to the weakening (depression of the immune system. Even a so-called high-energy diet often causes respiratory diseases. A diet deficient in proteins also affects cows after lactation, as opposed to a normative diet, and a reduced protein diet disturbs the microbial activity in the rumen and the synthesis of compounds which are important for both the cow and the calf, making room for the incidence of metabolic diseases, most

    Full Text Available Malignant catarrhal fever in Indonesia is caused by Ovine herpes virus 2 and considered as a disease with high mortality rate causing degeneratif and lymphoproliferative disease in cattle, buffalo and other ruminants. A total number of fifteen Bali cattle were naturally infected by Malignant Catarrhal Fever (MCF. Those cattle were meant to be experimental animals of research on infectious bovine rhinotracheitis (IBR, Septicaemia epizootica (SE, and bovine brucellosis. The clinical signs of those animals were sudden high fever, depression, anorexia, corneal opacity, mucopurulent oculo-nasal discharges and diarrhoea. Six of them were dead and the remaining cattle were slaughtered at extremis. On the basis of clinical, gross-pathological and histopathological findings, all cases were shown to be consistent and pathognomonic of MCF cases. These cases were regarded as an outbreak of MCF affecting Bali cattle which occurred during wet season and while in other paddock in that area there were a number of lambing sheep. This result confirms that Bali cattle is a very susceptible animal of MCF and the cases were very likely due to the spread of MCF virus from lambing sheep.

    Modern antidiabetic therapies should achieve low HbA1c values and avoid hypoglycaemic complications. The registry SIRTA included 1522 patients with type II diabetes mellitus (T2DM) from 306 German medical practices. Patients had an HbA1c > 6.5% under the maximum tolerated metformin dose. If required, they received combination therapy with other antidiabetics according to the guideline of the German Diabetes Society [Deutsche Diabetes Gesellschaft (DDG)] or usual medical practice. Patients were followed up for 6 months. The target criteria included the achievement of HbA1c target values and the emergence of severe hypoglycaemic episodes. Most patients (64.0%) were planned to achieve an HbA1c target < 6.5%, the standard target recommended by the 2009 DDG guideline valid throughout the registry. Primarily to reduce the individual risk for hypoglycaemia, 32.4% of patients had a less strict HbA1c-target of 6.5-7.0%. These targets were achieved by 31.3% and 44.3% of patients, respectively. Combination therapies increased from 45% to 56% over the 6 months registry. Four patients had severe hypoglycaemias (0.26%). The registry confirms results from other epidemiologic studies on the therapy of T2DM in everyday practice. The treatment strategies applied effectively reduced blood glucose and avoided severe hypoglycaemias. An early therapy of insufficiently controlled patients with T2DM is important, as lower baseline values facilitated achieving HbA1c targets. © 2014 The Authors.

    To assess the efficacy and safety of chicken type II collagen (CCII) in rheumatoid arthritis (RA) compared with methotrexate (MTX). We conducted a prospective, 24-week, followup, multicenter, double-blind, controlled study of CCII (0.1 mg/day) versus MTX (10 mg/week) in patients with active RA. Clinical assessments were performed at screening and at 12, 18, and 24 weeks of treatment. A total of 236 RA patients were included; 211 patients (89.4%) completed the 24-week followup. In both groups there was a decrease in pain, morning stiffness, tender joint count, swollen joint count, Health Assessment Questionnaire score, and investigator and patient assessment of function; all differences were statistically significant. In the MTX group, erythrocyte sedimentation rate and C-reactive protein level decreased. Rheumatoid factor did not change in either group. At 24 weeks, 68.57% of patients in the CCII group and 83.02% in the MTX group met the American College of Rheumatology 20% improvement criteria (ACR20), and 40.95% and 57.54%, respectively, met the ACR50 criteria. The ACR20 and ACR50 response rates in the CCII group were lower than those in the MTX group, and this difference was statistically significant (P < 0.05). Gastrointestinal symptoms were common in both groups. There were fewer and milder side effects in the CCII group than the MTX group. The difference in incidence of adverse events between the 2 groups was statistically significant (P < 0.05). CCII is effective in the treatment of RA. CCII is well tolerated, and the incidence of adverse events of CCII is lower than that of MTX.

    Background Data from selected centers show that robotic lobectomy (RL) is safe, effective and has comparable 30-day mortality to video assisted lobectomy (VATS). However, widespread adoption of RL is controversial. We used the STS-GTS-Database to evaluate quality metrics for these two minimally invasive lobectomy techniques. Methods A database query for primary clinical stage I or II NSCLC at high volume centers from 2009 to 2013 identified 1,220 RLs and 12,378 VATS. Quality metrics evaluated included operative morbidity, 30-day mortality and nodal upstaging (NU), defined as cN0 to pN1. Multivariable logistic regression was used to evaluate NU. Results RL patients were older, less active, less likely to be an ever smoker, and had higher BMI (all p<0.05). They were also more likely to have coronary heart disease or hypertension (all p<0.001) and to have had preoperative mediastinal staging (p<0.0001). RL operative times were longer (median 186 vs 173 min, p<0.001); all other operative parameters were similar. All postoperative outcomes were similar including complications and 30-day mortality (RL 0.6% vs VATS 0.8%, p=0.4). Median length of stay was 4 days for both, but a higher proportion of RLs stayed < 4 days: 48% vs 39%, p<0.001. NU overall was similar (p=0.6), but with trends favoring VATS in the cT1b group, and RL in the cT2a group. Conclusions RL patients had more co-morbidities and RL operative times were longer, but quality outcome measures including complications, hospital stay, 30-day mortality, and NU suggest RL and VATS are equivalent.

    The aim of the study was to analyze the effect of conventional glucose management, which aimed to maintain glucose levels stroke (IS) in a clinical practice setting. This was a multicenter, prospective cohort study of patients with acute IS. Patients were classified into four groups based on their initial 48-h capillary glucose levels and the administration of and response to corrective treatment: (i) untreated and maximum glucose levels <155 mg/dL (8.5 mmol/L) within the first 48 h; (ii) treated and good responders [glucose levels persistently <155 mg/dL (8.5 mmol/L)]; (iii) treated and non-responders [any glucose values ≥155 mg/dL (8.5 mmol/L) during the 24 h after the start of corrective treatment]; and (iv) untreated with any glucose value ≥155 mg/dL (8.5 mmol/L). The primary outcome was death or dependence at 3 months (blinded rater). A total of 213 patients were included. Ninety-seven (45.5%) patients developed glucose levels ≥155 mg/dL (8.5 mmol/L), 69 (71.1%) underwent corrective treatment and 31 patients underwent no corrective treatment at the physician's discretion [28 of whom had isolated values ≥155 mg/dL (8.5 mmol/L)]. Only 11 (16%) patients responded to conventional treatment, whereas 58 (84%) patients were non-responsive. Non-responders showed a twofold higher risk of death or dependence at 3 months (odds ratio, 2.472; 95% confidence interval, 1.096-5.576; P = 0.029). Lack of response to conventional treatment for glucose management in acute IS is frequent and associated with poor outcomes. © 2017 EAN.

    The aim of this clinical trial was to test the hypothesis whether adding the pectoral nerves (Pecs) block type II to the anesthetic procedure reduces opioid consumption during and after breast surgery. A prospective randomized double blind placebo-controlled study. A secondary hospital. 140 breast cancer stage 1-3 patients undergoing mastectomy or tumorectomy with sentinel node or axillary node dissection. Patients were randomized to receive either a Pecs block with levobupivacaine 0.25% (n=70) or placebo block with saline (n=70). The pain levels were evaluated by Numeric Rating Scale (NRS) pain scores at 15-minute intervals during the post anesthesia care unit stay time (PACU), at 2-hour intervals for the first 24h on the ward and at 4-hour intervals for the next 24h. Intraoperative and postoperative opioid consumption were recorded during the full stay. Patient satisfaction was evaluated upon discharge using a 10-point scale. Intraoperative sufentanil requirements were comparable for the Pecs and placebo group (8.0±3.5μg and 7.8±3.0μg, P=0.730). Patients in the Pecs group experienced significantly less pain than patients in the control group (P=0.048) during their PACU stay. Furthermore, patients in the Pecs group required significant less postoperative opioids (9.16±10.15mg and 14.97±14.38mg morphine equivalent, P=0.037) and required significant fewer postsurgical opioid administration interventions than patients in the control group (P=0.045). Both patient-groups were very satisfied about their management (9.6±0.6 and 9.1±1.8 on a 10-point scale, P=0.211). The Pecs block reduces postsurgical opioid consumption during the PACU stay time for patients undergoing breast surgery. Copyright © 2017 Elsevier Inc. All rights reserved.

    To investigate the safety and preliminary efficacy of OT-551, a disubstituted hydroxylamine with antioxidant properties, for the treatment of geographic atrophy (GA), the advanced atrophic form of age-related macular degeneration (AMD). The study was a single-center, open-label phase II trial, enrolling 10 participants with bilateral GA. Topical 0.45% OT-551 was administered in one randomly assigned eye three times daily for 2 years. Safety measures were assessed by complete ophthalmic examination, fundus photography, and review of symptoms. The primary efficacy outcome measure was the change in best corrected visual acuity at 24 months. Secondary efficacy measures included changes in area of GA, contrast sensitivity, microperimetry measurements, and total drusen area from baseline. Study drug was well tolerated and was associated with few adverse events. The mean change in BCVA at 2 years was +0.2 ± 13.3 letters in the study eyes and -11.3 ± 7.6 letters in fellow eyes (P = 0.0259). However, no statistically significant differences were found between the study and fellow eyes for all other secondary outcome measures. OT-551 was well tolerated by study participants and was not associated with any serious adverse effects. Efficacy measurements in this small study indicate a possible effect in maintaining visual acuity. However, the absence of significant effects on other outcomes measures in this study suggests that OT-551, in the current concentration and mode of delivery, may have limited or no benefit as a treatment for GA (ClinicalTrials.gov number, NCT00306488).

    Two consecutive phase II clinical studies were designed to evaluate the efficacy and safety of bolus and continuous infusion (CI) mitoxantrone (MTZ) in 39 patients with newly diagnosed acute lymphocytic leukemia (ALL). MTZ was used as part of the classical ALL induction regimen. Twenty patients were treated with bolus MTZ (10 mg/m2 for 3 days) combined with vincristine and prednisone. The same regimen was given to a second set of 19 patients, except that MTZ was administered as a 24-hr CI. Both groups received bimonthly intensifications with vincristine and prednisone for 3 years, along with oral maintenance therapy. Patients in the CI-MTZ study arm received additional MTZ on the first day of intensification cycles. Seventeen patients (85%) in the bolus arm and 15 patients (79%) in the CI arm achieved complete remission (CR). Median disease-free survivals (DFS) in the bolus and CI groups were 11 and 15 months after median follow-ups of 16 (3.5-96) and 13 (2.3-32) months, respectively. At 2.5 years, DFS rates were 29.4% and 34.4% in the bolus and CI groups (p > 0.05). There were no significant differences between two groups in rates of early death, degree of organ toxicity, or duration of neutropenia and thrombocytopenia. Significant cardiac toxicity was not observed in either group. Bolus or CI administration of MTZ was equally effective and was well tolerated. Neither the mode of administration nor increasing the dose intensity of MTZ by incorporating intensification cycles reduced relapse rates. Development of new antileukemia agents and novel treatment approaches are still needed to improve the high relapse rates in adult ALL once a complete response is achieved.

    Objective: To investigate the changes of serum levels of insulin-like growth factor II (IGF II) and adrenomedullin (ADM) in patients with essential hypertension. Methods: Serum IGF II and ADM levels were measured in 62 cases of hypertension and 40 controls with RIA. Results: Serum IGF II and ADM levels were significantly bigger in hypertensive patients than those in the controls (t = 4.454, p < 0.01; t = 3.992, p < 0.01). The serum IGF II level was significantly positively correlated to the serum ADM levels (r = 0.379, p < 0.05) and both were significantly positively correlated to the mean arterial pressure (r = 0.346, r = 0.353, p < 0.05) but not with BMI. Serum ADM levels increased gradually as the disease progressed from stage I to stage III (p < 0.05) with levels in stage III markedly higher than those in stage I (p < 0.01). In EH patients with heart and/or brain and/or renal complications the serum ADM levels were significantly higher than those in EH patients without complications (t = 2.050, p < 0.05). Such differences did not exist in the case of IGF II. Conclusion: Serum IGF II and ADM levels were increased markedly in hypertensive patients. These two factors were mutually positively correlated and both were positively correlated to mean arterial pressure. ADM levels increased gradually as the disease progressing but IGF II levels remained stable

    Time-to-surgery from cancer diagnosis has increased in the United States. We aimed to determine the association between time-to-surgery and oncologic outcomes in patients with resectable pancreatic ductal adenocarcinoma undergoing upfront surgery. The 2004-2012 National Cancer Database was reviewed for patients undergoing curative-intent surgery without neoadjuvant therapy for clinical stage I-II pancreatic ductal adenocarcinoma. A multivariable Cox model with restricted cubic splines was used to define time-to-surgery as short (1-14 days), medium (15-42), and long (43-120). Overall survival was examined using Cox shared frailty models. Secondary outcomes were examined using mixed-effects logistic regression models. Of 16,763 patients, time-to-surgery was short in 34.4%, medium in 51.6%, and long in 14.0%. More short time-to-surgery patients were young, privately insured, healthy, and treated at low-volume hospitals. Adjusted hazards of mortality were lower for medium (hazard ratio 0.94, 95% confidence interval, .90, 0.97) and long time-to-surgery (hazard ratio 0.91, 95% confidence interval, 0.86, 0.96) than short. There were no differences in adjusted odds of node positivity, clinical to pathologic upstaging, being unresectable or stage IV at exploration, and positive margins. Medium time-to-surgery patients had higher adjusted odds (odds ratio 1.11, 95% confidence interval, 1.03, 1.20) of receiving an adequate lymphadenectomy than short. Ninety-day mortality was lower in medium (odds ratio 0.75, 95% confidence interval, 0.65, 0.85) and long time-to-surgery (odds ratio 0.72, 95% confidence interval, 0.60, 0.88) than short. In this observational analysis, short time-to-surgery was associated with slightly shorter OS and higher perioperative mortality. These results may suggest that delays for medical optimization and referral to high volume surgeons are safe. Published by Elsevier Inc.

    Full Text Available We review here the epidemiological studies performed by our group on human retrovirus HTLV-I and HTLV-II infections and the associated diseases in French Guiana since 1984. French Guiana is an overseas French administrative district located between Brazil and Surinam. Its population is characterized by a large variety of ethnic groups, including several populations of African origin and various populations of Amerindian origin. Several epidemiological studies of large samples of pregnant women and in remote villages showed that HTLV-I is highly endemic in this area but is restricted to groups of African origin, especially the Noir-Marrons. In this endemic population, the results of segregation analysis in a genetic epidemiological study were consistent with the presence of a dominant major gene predisposing to HTLV-I infection, especially in children. In contrast, HTLV-II infection appears to be rare in French Guiana, having been found in only a few individuals of Brazilian origin. From a molecular point of view, the HTLV-I strains present in the Noir-Marrons, Creoles and Amerindians appear to originate from Africa, as they belong to the large cosmopolitan molecular subtype A.

    Full Text Available Aim: The aim was to study the chromosome analysis of arsenic affected cattle. Materials and Methods: 27 female cattle (21 arsenic affected and 6 normal were selected for cytogenetical study. The blood samples were collected, incubated, and cultured using appropriate media and specific methods. The samples were analyzed for chromosome number and morphology, relative length of the chromosome, arm ratio, and centromere index of X chromosome and chromosomal abnormalities in arsenic affected cattle to that of normal ones. Results: The diploid number of metaphase chromosomes in arsenic affected cattle as well as in normal cattle were all 2n=60, 58 being autosomes and 2 being sex chromosomes. From the centromeric position, karyotyping studies revealed that all the 29 pair of autosomes was found to be acrocentric or telocentric, and the sex chromosomes (XX were submetacentric in both normal and arsenic affected cattle. The relative length of all the autosome pairs and sex chrosomosome pair was found to be higher in normal than that of arsenic affected cattle. The mean arm ratio of X-chromosome was higher in normal than that of arsenic affected cattle, but it is reverse in case of centromere index value of X-chromosome. There was no significant difference of arm ratio and centromere index of X-chromosomes between arsenic affected and normal cattle. No chromosomal abnormalities were found in arsenic affected cattle. Conclusion: The chromosome analysis of arsenic affected cattle in West Bengal reported for the first time in this present study which may serve as a guideline for future studies in other species. These reference values will also help in comparison of cytological studies of arsenic affected cattle to that of various toxicants.

    Full Text Available Muscularity is a potential indicator for the selection of more productive cattle. Mapping quantitative trait loci (QTL for traits related to muscularity is useful to identify the genomic regions where the genes affecting muscularity reside. QTL analysis from a Limousin-Jersey double backcross herd was conducted using QTL Express software with cohort and breed as the fixed effects. Nine QTL suggested to have an association with muscularity were identified on cattle chromosomes BTA 1, 2, 3, 4, 5, 8, 12, 14 and 17. The myostatin gene is located at the centromeric end of chromosome 2 and not surprisingly, the Limousin myostatin F94L variant accounted for the QTL on BTA2. However, when the myostatin F94L genotype was included as an additional fixed effect, the QTL on BTA17 was also no longer significant. This result suggests that there may be gene(s that have epistatic effects with myostatin located on cattle chromosome 17. Based on the position of the QTL in base pairs, all the genes that reside in the region were determined using the Ensembl data base (www.ensembl.org. There were two potential candidate genes residing within these QTL regions were selected. They were Smad nuclear interacting protein 1 (SNIP1 and similar to follistatin-like 5 (FSTL5.

    In Experiment I, 4 female swamp buffaloes and 4 local cattle fed with the diet based on young maize and rice straw (80/20), and in experiment II, the same number and types of animals as in Experiment I were fed with the diet based on rice straw and rice bran (70/30). The animals were fed twice a day with the diets at 40, 60, 80, 95% of ad libitum intake. The digestibility of nutrients and N excretion were similar for cattle and buffaloes. The purine derivative:creatinine ratio (PDC) index was significantly affected by the level of feed intake (P < 0.001) in both the species. Large differences in urinary purine derivative (PD) excretion were observed, being much lower in buffaloes than in cattle. The regression analysis showed that urinary PD excretion rate per kg of digestible organic matter intake for cattle was higher than that for buffalo. The PDC index also followed the same pattern. The nitrogen retention increased with the supply of energy, both in cattle and buffaloes, indicating that the protein supply was similar. There was no consistent effect of time of day on spot sampling in buffalo and cattle. Buffaloes urinated less frequently than cattle, so sampling time was not really relevant. (author)

    Full Text Available Background and aims. Plasma rich in growth factors (PRGF is a concentrated suspension of growth factors, which is used to promote periodontal tissue regeneration. The aim of this randomized, controlled, clinical trial was to evaluate of the treatment of grade II mandibular molar furcation involvement using autogenous bone graft with and without PRGF. Materials and methods. In this double-blind clinical trial, thirty mandibular molars with grade II furcation involvement in 30 patients were selected. The test group received bone graft combined with PRGF, while the control group was treated with bone graft only. Clinical parameters included clinical probing depth (CPD, vertical clinical attachment level (V-CAL, horizontal clinical attachment level (H-CAL, location of gingival margin (LGM, surgically exposed horizontal probing depth of bony defect (E-HPD, vertical depth of bone crest (V-DBC, vertical depth of the base of bony defect (V-DBD, and length of the intrabony defect (LID. After six months, a re-entry surgery was performed. Data were analyzed by SPSS 14, using Kolmogorov, Mann-Whitney U, and paired t-test. Results. After 6 months, both treatment methods led to significant improvement in V-CAL and H-CAL and significant decreases in CPD, E-HPD, V-DBD and LID; there was no significant difference in LGM and V-DBC in any of the treated groups compared to the baseline values. Also, none of the parameters showed significant differences between the study groups. Conclusion. Although autogenous bone grafts, with or without PRGF, were successful in treating grade II furcation involvement, no differences between the study groups were observed.

    OBJECTIVE. Antisocial personality disorder (ASPD) is a risk factor for violence and is associated with poor treatment response when it is a co-morbid condition with substance abuse. It is an under-recognised clinical entity in the local Hong Kong setting, for which there are only a few available Chinese-language diagnostic instruments. None has been tested for its psychometric properties in the Cantonese-speaking population in Hong Kong. This study therefore aimed to assess the reliability and validity of the Chinese version of the ASPD subscale of the Structured Clinical Interview for the DSM-IV Axis II Disorders (SCID-II) in Hong Kong Chinese. METHODS. This assessment tool was modified according to dialectal differences between Mainland China and Hong Kong. Inpatients in Castle Peak Hospital, Hong Kong, who were designated for priority follow-up based on their assessed propensity for violence and who fulfilled the inclusion criteria for the study, were recruited. To assess the level of agreement, best-estimate diagnosis made by a multidisciplinary team was compared with diagnostic status determined by the SCID-II ASPD subscale. The internal consistency, sensitivity, and specificity of the subscale were also calculated. RESULTS. The internal consistency of the subscale was acceptable at 0.79, whereas the test-retest reliability and inter-rater reliability showed an excellent and good agreement of 0.90 and 0.86, respectively. Best-estimate clinical diagnosis-SCID diagnosis agreement was acceptable at 0.76. The sensitivity, specificity, positive and negative predictive values were 0.91, 0.86, 0.83, and 0.93, respectively. CONCLUSION. The Chinese version of the SCID-II ASPD subscale is reliable and valid for diagnosing ASPD in a Cantonese-speaking clinical population.

    The Byk LIA-mat CA125 II assay was compared with the Centocor IRMA CA125 II. Serum samples studied (n = 1012) were obtained from 652 apparently healthy females, 61 pregnant women, and 299 patients with benign and malignant gynecological tumors. The CA125 II assay value at the 95th percentile of the total healthy group was 29 kU/L for the LIA-mat and 32 kU/L for the Centocor assay. For the LIA-mat assay the 95th percentile was 31 kU/L (Centocor 36 kU/L) for the group 55 years of age. By using ROC curves we found the optimal pretreatment Byk LIA-mat CA125 II value differentiating between benign and malignant ovarian tumors to be 95 kU/L. Pretreatment CA125 values > 1000 kU/L were detected in serum samples of patients with advanced epithelial ovarian cancer.

    A retrospective study was conducted to identify and describe the distribution pattern of Leptospira serogroups in domestic animals in France. The population consisted of cattle herds and dogs with clinically suspected leptospirosis that were tested at the "Laboratoire des Leptospires" between 2008 and 2011. The laboratory database was queried for records of cattle and dogs in which seroreactivity in Leptospira microagglutination tests was consistent with a recent or current infection, excluding vaccine serogroups in dogs. A total of 394 cattle herds and 232 dogs were diagnosed with clinical leptospirosis, and the results suggested infection by the Leptospira serogroup Australis in 43% and 63%, respectively; by the Leptospira serogroup Grippotyphosa in 17% and 9%, respectively; and by the Leptospira serogroup Sejroe in 33% and 6%, respectively. This inventory of infecting Leptospira serogroups revealed that current vaccines in France are not fully capable of preventing the clinical form of the disease. © The American Society of Tropical Medicine and Hygiene.

    The aim of this study was to determine whether pretreatment status of thymidine phosphorylase (TP), and hypoxia-inducible factor alpha (HIF-1α) could predict pathologic response to neoadjuvant chemoradiation therapy with oxaliplatin and capecitabine (XELOXART) and outcomes for clinical stage II/III rectal cancer patients. A total of 180 patients diagnosed with clinical stage II/III rectal cancer received XELOXART. The status of TP, and HIF-1α were determined in pretreatment biopsies by immunohistochemistry (IHC). Tumor response was assessed in resected regimens using the tumor regression grade system and TNM staging system. 5-year disease free survival (DFS) and 5-year overall survival (OS) were evaluated with the Kaplan-Meier method and were compared by the log-rank test. Over expression of TP and low expression of HIF-1α were associated with pathologic response to XELOXART and better outcomes (DFS and OS) in clinical stage II/III rectal cancer patients (P rectal cancer received XELOXART. Additional well-designed, large sample, multicenter, prospective studies are needed to confirm the result of this study.

    Oral treatment with phosphodiesterase type 5 inhibitor (PDE5) is considered the first-line treatment for patients with erectile dysfunction (ED). Lodenafil carbonate (LC) is a novel PDE5. This is a phase II, prospective, randomized, double-blind, and placebo controlled clinical trial of LC. Efficacy end points were International Index of Sexual Function (IIEF) erectile domain, IIEF questions 3 and 4, and Sexual Encounter Profile (SEP) questions 2 and 3, before and after the use of LC or placebo. Seventy-two men older than 18 years, with ED for at least 6 months with stable sexual relationship were enrolled. Patients were randomized to placebo or LC 80 mg, 40 mg, or 20 mg and followed for 4 weeks. IIEF erectile domain scores before and after the use of medications were (mean +/- standard deviation [SD]): placebo: 11.9 +/- 3.4 and 12.6 +/- 5.5; LC 20 mg: 15.8 +/- 4.1 and 18.9 +/- 6.6; LC 40 mg: 11.9 +/- 4.4 and 15.4 +/- 8.1; LC 80 mg: 14.2 +/- 4.7 and 22.8 +/- 6.0 (ANOVA P < 0.01). The SEP-2 scores before and after the use of medications were (Mean +/- SD): placebo: 71.0 +/- 33.1 and 51.2 +/- 43.1; LC 20 mg 70.3 +/- 34.2 and 75.5 +/- 31.5; LC 40 mg: 48.4 +/- 42.1 and 60.8 +/- 42.5; LC 80 mg: 68.6 +/- 33.5 and 89.6 +/- 26.0. The SEP-3 scores were: placebo 23.3 +/- 27.6 and 33.6 +/- 42.3; LC 20 mg: 32.3 +/- 38.9 and 51.2 +/- 41.7; LC 40 mg: 39.7 +/- 44.7 and 46.7 +/- 41.1; LC 80 mg* 17.2 +/- 29.5 and 74.3 +/- 36.4 (*P < 0.05 for difference to placebo). The drug was well tolerated. Adverse reactions were mild and self-limited and included headache, rhinitis, flushing, color visual disorders, and dyspepsia. This study showed that the dosage of 80 mg of LC was significantly more efficacious than placebo and well tolerated.

    Since the first somatic cell cloned calves were born in Japan in 1998, more than 500 cloned cattle have been produced by somatic cell nuclear transfer and many studies concerning cloned cattle and their offspring have been conducted in this country. However, most of the results have been published in Japanese; thus, the data produced in this country is not well utilized by researchers throughout the world. This article reviews the 65 reports produced by Japanese researchers (62 written in Japanese and 3 written in English), which employed 171 clones and 32 offspring, and categorizes them according to the following 7 categories: (1) genetic similarities and muzzle prints, (2) hematology and clinical chemistry findings, (3) pathology, (4) growth performance, (5) reproductive performance, (6) meat production performance and (7) milk production performance. No remarkable differences in health status or reproductive performance were found among conventionally bred cattle, somatic cell cloned cattle surviving to adulthood and offspring of somatic cell cloned cattle. Similarities in growth performance and meat quality were observed between nuclear donor cattle and their clones. The growth curves of the offspring resembled those of their full siblings.

    The Sr concentration and isotope composition of tooth enamel from domesticated animals from two neighbouring Anglo-Saxon settlements, at Empingham (6-7th century) and Ketton (10-12th century) in Rutland, central England, are compared both with each other, and with associated human populations. Data from the Empingham II site form discrete fields in Sr concentration and isotope composition space for cattle, pig and sheep with a partial overlap of the human and pig fields. By contrast there is significant overlap in all the animal and human data fields from the Ketton site. The differences in data distribution between the two sites are attributed to animal husbandry techniques, as the surface geology of the two areas is very similar, implying geological factors are an unlikely cause of the difference. It is suggested that the grazing and feeding patterns of animals at the Empingham II site were controlled and restricted, whereas at the Ketton site the animals grazed and foraged freely over a common area. Strontium isotope variation within cattle molars from the two settlements show marked differences that reflect the nature of their feeding and rearing. The enamel from a cattle molar from the Empingham II site has a well-defined, systematic variation of Sr isotope composition with Sr concentration, whereas no such patterns exist in a comparable cattle molar from Ketton. Chemical and O isotope variations in the cattle tooth from Empingham II show sympathetic variation of Sr and Ba concentrations with Sr isotope composition from cusp to cervix. The cusp has higher Sr and Ba concentrations log (Sr/Ca) ratio of -3.1 and 87 Sr/ 86 Sr ratio of 0.71151 where as the cervical region of the enamel has log (Sr/Ca) = -3.3 and 87 Sr/ 86 Sr = 0.71061

    Arsenic poisoning due to contaminated subsoil water is one of the most alarming environment hazards in West Bengal, India. Cattle are also affected by arsenic due to ingestion of arsenic contaminated water, paddy straw, crops and vegetables. Thirty milch cattle having arsenic content in the range of 3.5 to 4.5 mg/kg in hair were chosen for this experiment from cattle of five respective villages in Nadia District, West Bengal, India. The cattle were divided into three groups containing 10 animals each. Group I cattle were treated with turmeric powder (Curcuma longa) 20 g/day orally for 60 days. Group II cattle were treated with turmeric powder (10 g/day) and Amaranthus spinosus powder (10 g/day) orally for 60 days. Group III cattle were treated with turmeric powder (10 g/day) and Eclipta alba powder (10 g/day) orally for 60 days. Ten apparently healthy milch cows with no history of exposure to arsenic were selected and kept as control group (group IV). Arsenic content in hair, faeces, urine and milk; different biochemical and haematological parameters and DNA fragmentation percentage assay were carried out before commencement of the treatment, after 30 days and after 60 days of treatment. The test drugs were found significantly (p < 0.05) effective to eliminate arsenic from the body and lead to significant improvement in different biochemistry, pathology and DNA fragmentation assay. These drugs also give protection from possible damage caused by arsenic exposure.

    Saccharification of cellulose is a promising technique for producing alternative source of energy. However, the efficiency of conversion of cellulose into soluble sugar using any currently available methodology is too low for industrial application. Many additives, such as surfactants, have been shown to enhance the efficiency of cellulose-to-sugar conversion. In this study, we have examined first whether cattle saliva, as an additive, would enhance the cellulase-catalyzed hydrolysis of cellulose, and subsequently elucidated the mechanism by which cattle saliva enhanced this conversion. Although cattle saliva, by itself, did not degrade cellulose, it enhanced the cellulase-catalyzed degradation of cellulose. Thus, the amount of reducing sugar produced increased approximately 2.9-fold by the addition of cattle saliva. We also found that non-enzymatic proteins, which were present in cattle saliva, were responsible for causing the enhancement effect. Third, the mechanism of cattle saliva mediated enhancement of cellulase activity was probably similar to that of the canonical surfactants. Cattle saliva is available in large amounts easily and cheaply, and it can be used without further purification. Thus, cattle saliva could be a promising additive for efficient saccharification of cellulose on an industrial scale. PMID:26402242

Good clinical outcomes have been reported with a variety of TKA prostheses. The cementless Hi-Tech Knee II cruciate-retaining (CR-type prosthesis, which has 6 fins at the anterior of the femoral component, posterior cruciate ligament (PCL retention, flat-on-flat surface component geometry, all-polyethylene patella, strong initial fixation by the center screw of the tibial base plate, 10 layers of titanium alloy fiber mesh, and direct compression molded ultra high molecular weight polyethylene (UHMWPE, is appropriate for TKA in the Japanese knee. The present study was performed to evaluate the clinical results of primary TKA in RA using the cementless Hi-Tech Knee II CR-type prosthesis. Materials and methods We performed 32 consecutive primary TKAs using cementless Hi-Tech Knee II CR-type prosthesis in 31 RA patients. The average follow-up period was 8 years 3 months. Clinical evaluations were performed according to the American Knee Society (KS system, knee score, function score, radiographic evaluation, and complications. Results The mean postoperative maximum flexion angle was 115.6°, and the KS knee score and function score improved to 88 and 70 after surgery, respectively. Complications, such as infection, occurred in 1 patient and revision surgery was performed. There were no cases of loosening in this cohort, and prosthesis survival rate was 96.9% at 12 years postoperatively. Conclusion These results suggest that TKA using the cementless Hi-Tech Knee II CR-type prosthesis is a very effective form of treatment in RA patients at 5 to 12 years postoperatively. Further long-term follow-up studies are required to determine the ultimate utility of this type of prosthesis.

    2011-12-01

    Mastitis occurs in numerous species. Antimicrobial agents are used for treatment of infectious mastitis in dairy cattle, other livestock, companion animals, and humans. Mastitis is an economically important disease of dairy cattle and most mastitis research has focused on epidemiology and control of bovine mastitis. Antibiotic treatment of clinical and subclinical mastitis in dairy cattle is an established component of mastitis control programs. Research on the treatment of clinical and subclinical mastitis in other dairy species such as sheep and goats has been less frequent, although the general principles of mastitis therapy in small ruminants are similar to those of dairy cattle. Research on treatment of clinical mastitis in humans is limited and as for other species empirical treatment of mastitis appears to be common. While antimicrobial susceptibility testing is recommended to direct treatment decisions in many clinical settings, the use of susceptibility testing for antibiotic selection for mastitis treatments of dairy cattle has been challenged in a number of publications. The principle objective of this review is to summarize the literature evaluating the question, "Does antimicrobial susceptibility predict treatment outcome for intramammary infections caused by common bacterial pathogens?" This review also addresses current issues related to antimicrobial use and treatment decisions for mastitis in dairy cattle. Information on treatment of mastitis in other species, including humans, is included although research appears to be limited. Issues related to study design, gaps in current knowledge and opportunities for future research are identified for bovine mastitis therapy.

    Objective: To explore the clinical significance of changes of serum IGF-II, SCC and CYFRA21-1 levels after operation in patients with carcinoma uterine cervix. Methods: Serum levels of IGF-II, SCC and CYFRA21-1 were determined with RIA repeatedly in 31 patients with carcinoma of uterine cervix (before operation 1 month after operation and 6 month after operation) and once in 35 controls. Results: Before operation,serum levels of IGF-II, SCC and CYFRA21-1 in the patients were significantly higher than those in the controls (P<0.01). One month after operation all the serum levels were approaching normal. Six month later,the levels in the patients without recurrence remained normal. However, the levels in the 6 patients with recurrence returned to those before operation again. Conclusion: Changes of serum IGF-II, SCC and CYFRA21-1 levels are closely related to the tumor burden and may be of prognostic importance. (authors)

    Phase II and III clinical studies were conducted to evaluate immunogenicity and safety of a novel DTaP-IPV vaccine consisting of Sabin inactivated poliovirus vaccine (sIPV) and diphtheria-tetanus-acellular pertussis vaccine (DTaP). A Phase II study was conducted in 104 healthy infants using Formulation H of the DTaP-sIPV vaccine containing high-dose sIPV (3, 100, and 100 D-antigen units for types 1, 2, and 3, respectively), and Formulations M and L, containing half and one-fourth of the sIPV in Formulation H, respectively. Each formulation was administered 3 times for primary immunization and once for booster immunization. A Phase III study was conducted in 342 healthy infants who received either Formulation M + oral polio vaccine (OPV) placebo or DTaP + OPV. The OPV or OPV placebo was orally administered twice between primary and booster immunizations. Formulation M was selected as the optimum dose. In the Phase III study, the seropositive rate was 100% for all Sabin strains after primary immunization, and the neutralizing antibody titer after booster immunization was higher than in the control group (DTaP + OPV). All adverse reactions were clinically acceptable. DTaP-sIPV was shown to be a safe and immunogenic vaccine.

    The objective of this study was to identify the most reliable approach for prevalence estimation of Mycobacterium avium ssp. paratuberculosis (MAP) infection in clinically healthy slaughtered cattle. Sampling of macroscopically suspect tissue was compared to systematic sampling. Specimens of ileum, jejunum, mesenteric and caecal lymph nodes were examined for MAP infection using bacterial microscopy, culture, histopathology and immunohistochemistry. MAP was found most frequently in caecal lymph nodes, but sampling more tissues optimized the detection rate. Examination by culture was most efficient while combination with histopathology increased the detection rate slightly. MAP was detected in 49/50 animals with macroscopic lesions representing 1.35% of the slaughtered cattle examined. Of 150 systematically sampled macroscopically non-suspect cows, 28.7% were infected with MAP. This indicates that the majority of MAP-positive cattle are slaughtered without evidence of macroscopic lesions and before clinical signs occur. For reliable prevalence estimation of MAP infection in slaughtered cattle, systematic random sampling is essential.

    Full Text Available Abstract Background Vitamin A is essential for normal growth, development, reproduction, cell proliferation, cell differentiation, immune function and vision. Hypovitaminosis A can lead to a series of pathological damage in animals. This report describes the case of hypovitaminosis A associated with secondary complications in calves. Case presentation From February to March in 2011, 2-and 3-month old beef calves presented with decreased eyesight, apparent blindness and persistent diarrhea occurred in a cattle farm of Hubei province, China. Based on history inspection and clinical observation, we made a tentative diagnosis of hypovitaminosis A. The disease was confirmed as a congenital vitamin A deficiency by determination of the concentrations of vitamin A in serum and feed samples. Furthermore, pathological and microbiological examination showed that the disease was associated with pathogenic Escherichia coli (E. coli infection and mucosal barriers damage in intestines. The corresponding treatments were taken immediately, and the disease was finally under control for a month. Conclusions To our knowledge, this is the first report of hypovitaminosis A coupled to secondary infection of E. coli in beef cattle, advancing our knowledge of how vitamin A affects infection and immunity in animals. This study could also be contributed to scientific diagnosis and treatments of complex hypovitaminosis A in cattle.

    Full Text Available Metritis is an important disease in dairy cattle which causes economical loses including decrease in milk yield, increase calving interval, treatment costs and death of ill cases. Septic metritis usually occurs within 2-10 days after parturition, and characterized clinically with sever toxemia associated with purulent odorous uterine discharge with or without retained placenta. In this study, serum levels of cTnI were measured in 50 female Holstein cattle with septicmetritis and compared with normal cows. cTnI of serum in disease and control groups were 0.017 ± 0.008 and 0.005 ± 0.000 ng/dl, respectively. Heart rate, respiratory rate and rectal temperature in disease cases were significantly higher than normal cattle. There was significant correlation with cTnI and heart rate and rectal temperature. Endotoxemia is one of possible reasons of elevation of serum cTnI. Cytokines and endotoxins originated from gram negative bacteria that cause myocardium depression and ventricular dilatation. Furthermore impairment of left ventricle function is a significant effect of septic shock.

    The process of drug development involves non-clinical and clinical studies. Non-clinical studies are conducted using different protocols including animal studies, which mostly follow the Good Laboratory Practice (GLP) regulations. During the early pre-clinical development process, also known as Go/No-Go decision, a drug candidate needs to pass through several steps, such as determination of drug availability (studies on pharmacokinetics), absorption, distribution, metabolism and elimination (ADME) and preliminary studies that aim to investigate the candidate safety including genotoxicity, mutagenicity, safety pharmacology and general toxicology. These preliminary studies generally do not need to comply with GLP regulations. These studies aim at investigating the drug safety to obtain the first information about its tolerability in different systems that are relevant for further decisions. There are, however, other studies that should be performed according to GLP standards and are mandatory for the safe exposure to humans, such as repeated dose toxicity, genotoxicity and safety pharmacology. These studies must be conducted before the Investigational New Drug (IND) application. The package of non-clinical studies should cover all information needed for the safe transposition of drugs from animals to humans, generally based on the non-observed adverse effect level (NOAEL) obtained from general toxicity studies. After IND approval, other GLP experiments for the evaluation of chronic toxicity, reproductive and developmental toxicity, carcinogenicity and genotoxicity, are carried out during the clinical phase of development. However, the necessity of performing such studies depends on the new drug clinical application purpose.

    Bovine ehrlichiosis is a tick-borne rickettsial disease caused by Anaplasma phagocytophilum. The disease can also be transmitted to humans. Outbreaks in cattle have been described in many European countries. In Belgium, infections caused by A. phagocytophilum have been reported in humans and dogs; however, this paper details the first report of ehrlichiosis in cattle herds in Belgium. The first case described was in a dairy herd located in eastern Belgium. Clinical signs included hyperthermia, polypnea, and swelling of the limbs. The other case was diagnosed in a second, mixed purpose herd in western Belgium. Within the second herd, all of the affected animals came from the same pasture. All animals in that pasture showed recurrent hyperthermia, and some also showed signs of mastitis and late-term abortions. Blood smears and serology revealed the presence of A. phagocytophilum in the majority of animals with pyrexia. Furthermore, the presence of leptospirosis, Neospora caninum, and Q fever antibodies was tested by serological analysis, but all results were negative. Paired serology for Adenovirus, BHV-4, BHV-1, BVD, PI3, and RSV-B did not show any significant seroconversion. Milk samples from cows affected by mastitis revealed minor pathogens. Fecal testing for the presence of Dictyocaulus viviparus in the first herd was negative. Recurrent pyrexia in pastured cattle is a non-specific sign, and can be related to several different pathogens. Bovine ehrlichiosis is transmitted by the tick species Ixodes ricinus which is known to be present throughout Belgium. Belgian practitioners should include ehrlichiosis in their differential diagnosis when confronted with pastured cattle suffering from recurrent pyrexia. Copyright © 2011 Elsevier GmbH.

    Fatty change of the liver (FCL) is very common in dairy cattle periparturiently. Many laboratory methods have been implicated in order to assist the diagnosis. To investigate whether FCL in dairy cattle could be evaluated by assessment of ornithine carbamoyl transferase (OCT) by means of an assay modified for bovine serum, other enzyme activity, serum bile acids (SBA) concentration, or other biochemical constituents. A total of 187 dairy cattle were included: 106 were suspected to have liver dysfunction and were examined after referral by veterinarians; 70 were clinically healthy with mild FCL; and 11 were clinically healthy without FCL. Blood and liver biopsy samples were obtained after clinical examination. Histologic examination by light microscopy and classification of samples according to the severity of FCL was done, and total lipid and triglyceride concentration was measured. In serum, OCT, aspartate aminotransferase (AST), alanine aminotransferase (ALT), sorbitol dehydrogenase (SDH), glutamate dehydrogenase (GDH), alkaline phosphatase (ALP), and gamma-glutamyltransferase (gamma-GT) activity as well as SBA, glucose, ketones, total bilirubin (tBIL), and nonesterified fatty acids (NEFA) concentration were measured. OCT and AST activity and tBIL concentration correlate well with the degree of FCL. SBA concentration does not contribute well to FCL diagnosis. The majority of FCL cases appeared within the first 21 days-in-milk (DIM). The majority of moderate-to-severe and severe FCL cases arose in the first 7 DIM. Except for OCT, AST, and tBIL, none of the biochemical tests used, including SBA, had sufficient discriminatory power to differentiate reliably between mild and severe FCL because of poor sensitivity. A weak correlation between clinical signs and the extent of FCL was evident.

    Full Text Available The shearing operation can provide double benefits to the cattle: they can become more heat tolerant and the tick infestation decreases. The cattle tick Rhipicephalus (Boophilus microplus causes great losses to dairy cattle, especially to the Holstein cattle because they are very susceptible to this tick. Its control is becoming each day more difficult, owing to the increasing resistance to acaricides they are acquiring. The objective of this work was to study the growing of haircoat following shearing. We made our experiment with 17 animals, 7 females and 10 males. They were shaved on the anterior third (head, neck, dewlap, scapula and arm of one side, at random. The work was performed in two steps: they were shorn for the first time on August 2nd 2012, with a size 10 blade in a clipper Oster model GoldenA5, which left the fur coat 2 mm long. Then we evaluated the hair length growing by collecting fortnightly three sample of hairs in the middle of the scapula, with  electric pliers, modified for this purpose, in both sides of the animals, sheared and non-sheared, until 30 days after this shearing. The three hair samples were put inside a little plastic bag per animal. Meanwhile, as we thought that the animals shearing had to be done closer to the skin, we decided to shear them again (in the same side shorn before, on October 2nd 2012. We changed our procedure using the same machine, but now with a blade size 30, which left the fur coat 1mm thick. After that, we collected again, fortnightly, samples of hairs on both sides during 2 months. The 10 longest hairs in the plastig bag were measured using a graph paper and the average per animal was calculated in each data and blade. A random design was applied for statistical analysis, the hair length of both sides, sheared and non sheared were compared by a two related samples tests – Wilcoxon, in a non parametric test, using the SPSSP 12.0 program, in each data within each blade.

    Survival rates for patients with medulloblastoma have improved in the last decades but for those who relapse outcome is dismal and new approaches are needed. Emerging drugs have been tested in the last two decades within the context of phase I/II trials. In parallel, advances in genetic profiling have permitted to identify key molecular alterations for which new strategies are being developed. We performed a systematic review focused on the design and outcome of early-phase trials evaluating new agents in patients with relapsed medulloblastoma. PubMed, clinicaltrials.gov, and references from selected studies were screened to identify phase I/II studies with reported results between 2000 and 2015 including patients with medulloblastoma aged <18 years. A total of 718 studies were reviewed and 78 satisfied eligibility criteria. Of those, 69% were phase I; 31% phase II. Half evaluated conventional chemotherapeutics and 35% targeted agents. Overall, 662 patients with medulloblastoma/primitive neuroectodermal tumors were included. The study designs and the response assessments were heterogeneous, limiting the comparisons among trials and the correct identification of active drugs. Median (range) objective response rate (ORR) for patients with medulloblastoma in phase I/II studies was 0% (0-100) and 6.5% (0-50), respectively. Temozolomide containing regimens had a median ORR of 16.5% (0-100). Smoothened inhibitors trials had a median ORR of 8% (3-8). Novel drugs have shown limited activity against relapsed medulloblastoma. Temozolomide might serve as backbone for new combinations. Novel and more homogenous trial designs might facilitate the development of new drugs. © 2017 The Authors. Cancer Medicine published by John Wiley & Sons Ltd.

    Adjuvant chemotherapy for stage II colon cancer is a controversial practice and is not recommended by the French Consensus Conference outside of therapeutic trial. To assess, within a well-defined population, the influence of hospital characteristics in this practice. In the Rhône-Alpes region (10% of the French population), 534 patients presenting with colon cancer stage II were operated on in 81 hospitals in the year 2000. The influence of hospital characteristics on the use of adjuvant chemotherapy was assessed using a multivariate logistic regression. Overall, 19.5% of patients received adjuvant chemotherapy. Younger age, T4 tumour, hospital volume lower than 20 colon cancer surgeries [odds ratio (OR) 2.96; Pclinical complications at diagnosis were independently associated with higher rates of chemotherapy. On the other hand, a number of examined lymph nodes lower than recommendations did not have any influence on chemotherapy use. Hospital characteristics had independently influenced the practice of adjuvant chemotherapy in stage II colon cancer. The more important institutional factor was the hospital procedure volume. The decisions of the multidisciplinary committees appeared at times paradoxical; a more comprehensive evaluation of this practice is needed.

In each one of them has been done at least a bone scanning during the diagnosis. In 52 cases carried out sericeous dosages of CA 15-3 and in some cases it was necessary to administer Samarium-153 EDTMP as palliative therapy of bone pain. The presence of secondary gamma-graphic focuses was 0/84 cases (0%) in clinical stage II, 54/265 cases (20%) in III and 41/91 cases (45%) in IV. The one focus appeared in 6.7% of the cases. In 7 of the 52 cases that received sericeous dosages of CA 15-3 were detected secondary osseous lesions, and 5 of them presented a marker elevation. The bone scanning has shown in many cases the presence of getters focuses in singular places of skeleton, urinary excretory system or mammary tissue. The gamma rays from Sm-153 allowed us to get some appropriate basal views post-therapy of the secondary lesions. The results show that the great incidence of secondary lesions in the skeleton occurred in cases of stages III and IV unlike other countries. The serial repetition of the radioisotope scanning. The presence of one focus in the skeleton of a patient with a well-known neoplasia makes us to do a careful evaluation of the focus nature. The presence of tracer accumulation in the kidney, ureter and bladder allows us to infer the pathology of excretory system that is the first evidence of its presence in many cases.

    2003-01-01

    Full Text Available Depending on the age and production category, cattle show different sensitivity towards certain mycotoxins. Microflora of the rumen degrades to a different degree and inactivates mycotoxins. In the work are presented the most important mycotoxicoses of cattle caused by fungal metabolites from the genera Fusarium, Aspergillus and Penicillium. Poisoning of cattle in our area is most often caused by Zearalenone, Dioxinivalenol, T-2 toxin, Ochratoxin A and Aflatoxin, but in the work are also presented Fumonisin B1 and B2. The work also describes preventive possibilities and protection of animal health from the effects of mycotoxins.

    Artificial selection towards a desired phenotype/trait has modified the genomes of livestock dramatically that generated breeds that greatly differ in morphology, production and environmental adaptation traits. Angus cattle are among the famous cattle breeds developed for superior beef quality. This paper aimed at exploring genomic regions under selection in Angus cattle that are associated with meat quality traits and other associated phenotypes. The whole genome of 10 Angus cattle was compared with 11 Hanwoo (A-H) and 9 Jersey (A-J) cattle breeds using a cross-population composite likelihood ratio (XP-CLR) statistical method. The top 1% of the empirical distribution was taken as significant and annotated using UMD3.1. As a result, 255 and 210 genes were revealed under selection from A-H and A-J comparisons, respectively. The WebGestalt gene ontology analysis resulted in sixteen (A-H) and five (A-J) significantly enriched KEGG pathways. Several pathways associated with meat quality traits (insulin signaling, type II diabetes mellitus pathway, focal adhesion pathway, and ECM-receptor interaction), and feeding efficiency (olfactory transduction, tight junction, and metabolic pathways) were enriched. Genes affecting beef quality traits (e.g., FABP3, FTO, DGAT2, ACS, ACAA2, CPE, TNNI1), stature and body size (e.g., PLAG1, LYN, CHCHD7, RPS20), fertility and dystocia (e.g., ESR1, RPS20, PPP2R1A, GHRL, PLAG1), feeding efficiency (e.g., PIK3CD, DNAJC28, DNAJC3, GHRL, PLAG1), coat color (e.g., MC1-R) and genetic disorders (e.g., ITGB6, PLAG1) were found to be under positive selection in Angus cattle. The study identified genes and pathways that are related to meat quality traits and other phenotypes of Angus cattle. The findings in this study, after validation using additional or independent dataset, will provide useful information for the study of Angus cattle in particular and beef cattle in general.

    Full Text Available Abstract Background Bovine herpesvirus type-1 (BHV-1 is an important pathogen of cattle that presents with a variety of clinical signs, including the upper respiratory tract infection infectious bovine rhinotracheitis (IBR. A seroepidemiological study of BHV-1 antibodies was conducted in England from 2002 – 2004: 29,782 blood samples were taken from 15,736 cattle from 114 herds which were visited on up to three occasions. Antibody concentration was measured using a commercial ELISA. Farm management information was collected using an interview questionnaire, and herd size and cattle movements were obtained from the cattle tuberculosis testing database and the British Cattle Movement Service. Hierarchical statistical models were used to investigate associations between cattle and herd variables and the continuous outcome percentage positive (PP values from the ELISA test in unvaccinated herds. Results There were 7 vaccinated herds, all with at least one seropositive bovine. In unvaccinated herds 83.2% had at least one BHV-1 seropositive bovine, and the mean cattle and herd BHV-1 seroprevalence were 42.5% and 43.1% respectively. There were positive associations between PP value, age, herd size, presence of dairy cattle. Adult cattle in herds with grower cattle had lower PP values than those in herds without grower cattle. Purchased cattle had significantly lower PP values than homebred cattle, whereas cattle in herds that were totally restocked after the foot-and-mouth epidemic in 2001 had significantly higher PP values than those in continuously stocked herds. Samples taken in spring and summer had significantly lower PP values than those taken in winter, whereas those taken in autumn had significantly higher PP values than those taken in winter. The risks estimated from a logistic regression model with a binary outcome (seropositive yes/no were similar. Conclusion The prevalence of BHV-1 seropositivity in cattle and herds has increased since

    This position paper reviews physical and mechanical properties of thermoplastic resin used for non-metal clasp dentures, and describes feature of each thermoplastic resin in clinical application of non-metal clasp dentures and complications based on clinical experience of expert panels. Since products of thermoplastic resin have great variability in physical and mechanical properties, clinicians should utilize them with careful consideration of the specific properties of each product. In general, thermoplastic resin has lower color-stability and higher risk for fracture than polymethyl methacrylate. Additionally, the surface of thermoplastic resin becomes roughened more easily than polymethyl methacrylate. Studies related to material properties of thermoplastic resin, treatment efficacy and follow-up are insufficient to provide definitive conclusions at this time. Therefore, this position paper should be revised based on future studies and a clinical guideline should be provided. Copyright © 2014 Japan Prosthodontic Society. Published by Elsevier Ltd.

    An experiment was conducted to evaluate the capabilities of dual photon absorptiometry (PA), radiographic photometry (RP), and ultrasound (U) to estimate bone mineral content (BMC) and bone strength of a group of bovine third metacarpals (McIII). Metacarpals were chosen for evaluating BMC and bone strength because of their accessibility and susceptibility to biomechanical stress. The right and left McIII of 14 Angus heifers (24 to 32 mo of age) were collected at slaughter and all soft tissues (including periosteum) were removed. The BMC was estimated at both the midpoint and 3 cm proximal to the midpoint on the McIII diaphysis. Metacarpals then were tested by three-point bending to determine breaking load (BL) and breaking strength (BS). Bones were reassembled and two 2-cm sections were removed, one at the midpoint and one 1 cm proximal to the midpoint section. Sections then were ashed and ash content was expressed as grams per 2-cm slice and defined as BMC. Correlation coefficients (r) between BMC vs PA, RP, and U were .908 (P < .0001), .967 (P < .0001), and .565 (P < .0001), respectively; r values between BS vs PA, RP, and U were .406 (P < 05), .429 (P < .05), and .499 (P < .01), respectively, and r values between BL vs PA, RP, and U were .870 (P < .0001), .865 (P < .0001), and .588 (P < .001), respectively. These data indicate that noninvasive techniques are useful in predicting BMC and BL in the bovine

    After 1952 the building of the Department of Stomatology was no more able to fulfill the increased demands, when the independent dental education had been started at the Medical University of Budapest. The leadership of the new Dental Faculty--officially founded in 1955--was looking for a solution to find a new building for clinical purposes. Finally in 1959 the new dental departments moved to a once residential building at Mikszáth Kálmán Square converted into dental clinics. This site had been in operation until the opening of the New Dental Education Center in 2007.

    The aim of the study was to clinically evaluate Empress II inlays cemented with a dual-curing bonding agent and a self-curing luting system. Forty patients were selected to receive one Empress II inlay. Empress II is a heat-pressed glass ceramic containing lithium disilicate and lithium orthophosphate crystals, purported to provide higher stress resistance and improved strength. The restorations were placed between March and May 2000. Recalls were performed after 6, 12, 24, and 36 months. At the 3-year recall, 7 patients were lost to follow-up. Inlays were evaluated for postoperative sensitivity, marginal integrity, marginal leakage, color stability, surface staining, retention, and surface crazing (microcracks). At the 3-year recall, all the restorations were in place and only one showed postoperative sensitivity (at the first recall, 1 week after placement). Only 3 inlays showed slight marginal staining, and 4 inlays showed gaps, with little surface staining or microcracks. No inlay debonded or fractured during theobservation period. All the evaluated inlays were in place and acceptable.

    Worldwide afflictions of the claws belong to the economically important diseases in dairy cattle. The significance of laminitis has gained importance in the last years since the condition is regarded as the most important predisposing factor for the development of lesions such as sole ulcer, white line disease and heel horn erosion. Apart from the clinical stages (acute, subacute, chronic, chronic-recurrent) there is also a subclinical form of laminitis which does not cause lameness. It is characterized by soft yellowish sole and heel horn with haemorrhages in the sole and along the white line. Laminitis is a multifactorial event in which nutrition, genetic disposition and the perinatal period, combined with the associated diseases of high-yielding cows, have a particular significance. Currently, two principally different hypotheses on the pathogenesis are discussed. The generally accepted theory bases on a disturbance in the microcirculation of the corium. According to the other theory the circulatory disturbances are secondary to changes which occur in the horn producing cells of the stratum basale of the epidermis. The predisposing factors and the pathogenesis of laminitis are discussed in the light of possible therapeutic and prophylactic measures.

    There are limited effective therapies for most patients with relapsed diffuse large B-cell lymphoma (DLBCL). We conducted a phase II trial of the multi-targeted vascular endothelial growth factor receptor (VEGFR) kinase inhibitor, sunitinib, 37.5 mg given orally once daily in adult patients with relapsed or refractory DLBCL. Of 19 enrolled patients, 17 eligible patients were evaluable for toxicity and 15 for response. No objective responses were seen and nine patients achieved stable disease (median duration 3.4 months). As a result, the study was closed at the end of the first stage. Grades 3-4 neutropenia and thrombocytopenia were observed in 29% and 35%, respectively. There was no relationship between change in circulating endothelial cell numbers (CECs) and bidimensional tumor burden over time. Despite some activity in solid tumors, sunitinib showed no evidence of response in relapsed/refractory DLBCL and had greater than expected hematologic toxicity.

    This work aimed at characterizing the thermal balance of Nellore cattle from the system of indirect calorimetry using a facial mask. The study was conducted at the Animal Biometeorology Laboratory of the São Paulo State University, Jaboticabal, Brazil. Five male Nellore weighing 750 ± 62 kg, at similar ages and body conditions were distributed in four 5 × 5 Latin squares (5 days of records and five schedules) during 20 days. Physiological and environmental measurements were obtained from the indirect calorimetry system using a facial mask. Respiratory parameters, hair coat, skin, and rectal temperature were continuously recorded. From this, metabolic heat production, sensible and latent ways of heat transfer were calculated. Metabolic heat production had an average value of 146.7 ± 0.49 W m-2 and did not change ( P > 0.05) over the range of air temperature (24 to 35 °C). Sensible heat flow reached 60.08 ± 0.81 W m-2 when air temperature ranged from 24 to 25 °C, being negligible in conditions of temperature above 33 °C. Most of the heat produced by metabolism was dissipated by cutaneous evaporation when air temperature was greater than 30 °C. Respiratory parameters like respiratory rate and ventilation remained stable ( P > 0.05) in the range of temperature studied. Under shade conditions and air temperature range from 24 to 35 °C, metabolic heat production, respiratory rate, and ventilation of mature Nellore cattle remain stable, which is indicative of low energetic cost to the thermoregulation.

    There is a clear link between irregular breathing and errors in medical imaging and radiation treatment. The audiovisual biofeedback system is an advanced form of respiratory guidance that has previously demonstrated to facilitate regular patient breathing. The clinical benefits of audiovisual biofeedback will be investigated in an upcoming multi-institutional, randomised, and stratified clinical trial recruiting a total of 75 lung cancer patients undergoing radiation therapy. To comprehensively perform a clinical evaluation of the audiovisual biofeedback system, a multi-institutional study will be performed. Our methodological framework will be based on the widely used Technology Acceptance Model, which gives qualitative scales for two specific variables, perceived usefulness and perceived ease of use, which are fundamental determinants for user acceptance. A total of 75 lung cancer patients will be recruited across seven radiation oncology departments across Australia. Patients will be randomised in a 2:1 ratio, with 2/3 of the patients being recruited into the intervention arm and 1/3 in the control arm. 2:1 randomisation is appropriate as within the interventional arm there is a screening procedure where only patients whose breathing is more regular with audiovisual biofeedback will continue to use this system for their imaging and treatment procedures. Patients within the intervention arm whose free breathing is more regular than audiovisual biofeedback in the screen procedure will remain in the intervention arm of the study but their imaging and treatment procedures will be performed without audiovisual biofeedback. Patients will also be stratified by treating institution and for treatment intent (palliative vs. radical) to ensure similar balance in the arms across the sites. Patients and hospital staff operating the audiovisual biofeedback system will complete questionnaires to assess their experience with audiovisual biofeedback. The objectives of this

    Full Text Available Inflammation is thought to be involved in the pathophysiology of bipolar disorder (BP and metabolic syndrome. Prior studies evaluated the association between metabolic profiles and cytokines only during certain mood states instead of their changes during treatment. We enrolled drug-naïve patients with BP-II and investigated the correlation between changes in mood symptoms and metabolic indices with changes in plasma cytokine levels after 12 weeks of pharmacological treatment. Drug-naïve patients (n = 117 diagnosed with BP-II according to DSM-IV criteria were recruited. Metabolic profiles (cholesterol, triglyceride, HbA1C, fasting serum glucose, body mass index (BMI and plasma cytokines (TNF-α, CRP, IL-6, and TGF-β were measured at baseline and 2, 8, and 12 weeks post-treatment. To adjust within-subject dependence over repeated assessments, multiple linear regressions with generalized estimating equation methods were used. Seventy-six (65.0% patients completed the intervention. Changes in plasma CRP were significantly associated with changes in BMI (P = 1.7E-7 and triglyceride (P = 0.005 levels. Changes in plasma TGF-β1 were significantly associated with changes in BMI (P = 8.2E-6, cholesterol (P = 0.004, and triglyceride (P = 0.006 levels. However, changes in plasma TNF-α and IL-6 were not associated with changes in any of the metabolic indices. Changes in Hamilton Depression Rating Scale scores were significantly associated with changes in IL-6 (P = 0.003 levels; changes in Young Mania Rating Scale scores were significantly associated with changes in CRP (P = 0.006 and TNF-α (P = 0.039 levels. Plasma CRP and TGF-β1 levels were positively correlated with several metabolic indices in BP-II after 12 weeks of pharmacological intervention. We also hypothesize that clinical symptoms are correlated with certain cytokines. These new findings might be important evidence that inflammation is the pathophysiology

    Clinical trials evaluating medicines, medical devices, and procedures now commonly assess the economic value of these interventions. The growing number of prospective clinical/economic trials reflects both widespread interest in economic information for new technologies and the regulatory and reimbursement requirements of many countries that now consider evidence of economic value along with clinical efficacy. As decision makers increasingly demand evidence of economic value for health care interventions, conducting high-quality economic analyses alongside clinical studies is desirable because they broaden the scope of information available on a particular intervention, and can efficiently provide timely information with high internal and, when designed and analyzed properly, reasonable external validity. In 2005, ISPOR published the Good Research Practices for Cost-Effectiveness Analysis Alongside Clinical Trials: The ISPOR RCT-CEA Task Force report. ISPOR initiated an update of the report in 2014 to include the methodological developments over the last 9 years. This report provides updated recommendations reflecting advances in several areas related to trial design, selecting data elements, database design and management, analysis, and reporting of results. Task force members note that trials should be designed to evaluate effectiveness (rather than efficacy) when possible, should include clinical outcome measures, and should obtain health resource use and health state utilities directly from study subjects. Collection of economic data should be fully integrated into the study. An incremental analysis should be conducted with an intention-to-treat approach, complemented by relevant subgroup analyses. Uncertainty should be characterized. Articles should adhere to established standards for reporting results of cost-effectiveness analyses. Economic studies alongside trials are complementary to other evaluations (e.g., modeling studies) as information for decision

    At a human/livestock/wildlife interface, Escherichia coli populations were used to assess the risk of bacterial and antibiotic resistance dissemination between hosts. We used phenotypic and genotypic characterization techniques to describe the structure and the level of antibiotic resistance of E. coli commensal populations and the resistant Enterobacteriaceae carriage of sympatric African buffalo (Syncerus caffer caffer) and cattle populations characterized by their contact patterns in the southern part of Hwange ecosystem in Zimbabwe. Our results (i) confirmed our assumption that buffalo and cattle share similar phylogroup profiles, dominated by B1 (44.5%) and E (29.0%) phylogroups, with some variability in A phylogroup presence (from 1.9 to 12%); (ii) identified a significant gradient of antibiotic resistance from isolated buffalo to buffalo in contact with cattle and cattle populations expressed as the Murray score among Enterobacteriaceae (0.146, 0.258, and 0.340, respectively) and as the presence of tetracycline-, trimethoprim-, and amoxicillin-resistant subdominant E. coli strains (0, 5.7, and 38%, respectively); (iii) evidenced the dissemination of tetracycline, trimethoprim, and amoxicillin resistance genes (tet, dfrA, and blaTEM-1) in 26 isolated subdominant E. coli strains between nearby buffalo and cattle populations, that led us (iv) to hypothesize the role of the human/animal interface in the dissemination of genetic material from human to cattle and toward wildlife. The study of antibiotic resistance dissemination in multihost systems and at anthropized/natural interface is necessary to better understand and mitigate its multiple threats. These results also contribute to attempts aiming at using E. coli as a tool for the identification of pathogen transmission pathway in multihost systems.

    Full Text Available The aim of the randomized controlled single blind study is to evaluate the treatment of Miller′s class II gingival recessions by coronally positioned flap (CPF with or without acellular dermal matrix allograft (ADMA. Ten patients with 20 sites with maxillary bilateral Miller′s class II facial recession defects were selected randomly into two groups of test (ADMA+CPF and control (CPF alone group with each group having 10 recession defects to be treated. The clinical parameters included plaque index (PI, gingival index (GI, probing pocket depth (PPD, clinical attachment level (CAL, recession height (RH, recession width (RW, height of the keratinized tissue (HKT, and thickness of the keratinized tissue (TKT. These measurements were recorded at baseline and after 6 months post-surgery. Statistical analysis was made by the paired "t" test for intragroup and intergroup comparison was done by the unpaired "t" test. The percentage of root coverage for both the experimental and control groups were 82.2% and 50%, respectively. The changes from baseline to 6 months were significant in both the groups for PD, CAL, and RH; however, for parameters such as RW, HKT, and TKT significance was seen only in the experimental group. On comparison between two groups, only TKT showed statistically significance. It can be concluded that the amount of root coverage obtained with ADMA + CPF was superior compared to CPF alone.

    2016-01-01

    Full Text Available There are many clinical and objectively defined parameters that are used to evaluate a person's disability. Since the World Health Organisation has presented the WHODAS II as a means of objectively measuring subjectively defined functions, greater attention has been focused on self-rated health. Only a few studies, however, have been conducted about differences between self-rated health and objectively defined parameters. The survey for this study was conducted on the basis of WHODAS II and the population in Latvia with spinal cord injury. Respondents were between 18 and 65, and 98 questionnaires were analysed. The results show that people with spinal cord injury on average rate their functioning as limited (33–40 points of 100. Most respondents have been declared to be disabled, which is defined as very serious or severe functional disorders. More than 40% have paid jobs, while one-third do not work for reasons of health. The research shows that there is a close coherence (p< 0.05 between individual, objectively and clinically defined indicators on the one hand and the aspects of the questionnaire in which physical functioning was an important factor on the other hand. In order to understand the real functional abilities of patients and the individual factors that influence those abilities, it is necessary to define functional self-rated health in addition to objectively defined indicators.

    Full Text Available Dens invaginatus (DI is a malformation of teeth probably resulting from an infolding of the dental papilla during tooth development. DI is classified as type I, II, and III by Oehlers depending on the severity of malformation. The maxillary lateral incisor is the most commonly affected tooth. Structural defects do exist in the depth of the invagination pits, and as a consequence, the early development of caries and the subsequent necrosis of the dental pulp, as well as abscess and cyst formation are clinical implications associated with DI. Occasionally, we can see more than one developmental anomaly occurring in a single tooth. In such cases it becomes important to identify the anomalies and initiate a proper treatment plan for good prognosis. In this paper, an unusual case of DI which clinically presented as a huge talons cusp affecting a mandibular lateral incisor tooth is described. This case report illustrates grinding of the talons cusp followed by nonsurgical endodontic management of dens invaginatus type II with an immature apex and periapical lesions, in which Mineral Trioxide Aggregate (MTA shows a complete periapical healing with bone formation at the site of the lesions.

    There is a clear link between irregular breathing and errors in medical imaging and radiation treatment. The audiovisual biofeedback system is an advanced form of respiratory guidance that has previously demonstrated to facilitate regular patient breathing. The clinical benefits of audiovisual biofeedback will be investigated in an upcoming multi-institutional, randomised, and stratified clinical trial recruiting a total of 75 lung cancer patients undergoing radiation therapy. To comprehensively perform a clinical evaluation of the audiovisual biofeedback system, a multi-institutional study will be performed. Our methodological framework will be based on the widely used Technology Acceptance Model, which gives qualitative scales for two specific variables, perceived usefulness and perceived ease of use, which are fundamental determinants for user acceptance. A total of 75 lung cancer patients will be recruited across seven radiation oncology departments across Australia. Patients will be randomised in a 2:1 ratio, with 2/3 of the patients being recruited into the intervention arm and 1/3 in the control arm. 2:1 randomisation is appropriate as within the interventional arm there is a screening procedure where only patients whose breathing is more regular with audiovisual biofeedback will continue to use this system for their imaging and treatment procedures. Patients within the intervention arm whose free breathing is more regular than audiovisual biofeedback in the screen procedure will remain in the intervention arm of the study but their imaging and treatment procedures will be performed without audiovisual biofeedback. Patients will also be stratified by treating institution and for treatment intent (palliative vs. radical) to ensure similar balance in the arms across the sites. Patients and hospital staff operating the audiovisual biofeedback system will complete questionnaires to assess their experience with audiovisual biofeedback. The objectives of this

    Full Text Available Abstract Background Observational studies have documented a potential protective effect of physical exercise in older adults who are at risk for developing Alzheimer's disease. The Fitness for the Ageing Brain II (FABS II study is a multicentre randomized controlled clinical trial (RCT aiming to determine whether physical activity reduces the rate of cognitive decline among individuals with Alzheimer's disease. This paper describes the background, objectives of the study, and an overview of the protocol including design, organization and data collection methods. Methods/Design The study will recruit 230 community-dwelling participants diagnosed with Alzheimer's disease. Participants will be randomly allocated to two treatment groups: usual care group or 24-week home-based program consisting of 150 minutes per week of tailored moderate physical activity. The primary outcome measure of the study is cognitive decline as measured by the change from baseline in the total score on the Alzheimer's disease Assessment Scale-Cognitive section. Secondary outcomes of interest include behavioral and psychological symptoms, quality of life, functional level, carer burden and physical function (strength, balance, endurance, physical activity. Primary endpoints will be measured at six and twelve months following the baseline assessment. Discussion This RCT will contribute evidence regarding the potential benefits of a systematic program of physical activity as an affordable and safe intervention for people with Alzheimer's disease. Further, if successful, physical activity in combination with usual care has the potential to alleviate the symptoms of Alzheimer's disease and improve its management and the quality of life of patients and their carers.

    In many rangeland settings, there is more than one potential poisonous plant. Two poisonous plants that are often found growing simultaneously in the same location in North American rangelands are death camas (Zigadenus spp.) and low larkspur (Delphinium spp.). The objective of this study was to determine if co-administration of death camas would exacerbate the toxicity of low larkspur in cattle. Cattle dosed with 2.0 g of death camas/kg BW showed slight frothing and lethargy, whereas cattle dosed with both death camas and low larkspur showed increased clinical signs of poisoning. Although qualitative differences in clinical signs of intoxication in cattle co-treated with death camas and low larkspur were observed, there were not any significant quantitative differences in heart rate or exercise-induced muscle fatigue. Co-treatment with death camas and low larkspur did not affect the serum zygacine kinetics, however, there was a difference in the larkspur alkaloid kinetics in the co-exposure group. Overall, the results from this study suggest that co-exposure to death camas and low larkspur is not significantly more toxic to cattle than exposure to the plants individually. The results from this study increase our knowledge and understanding regarding the acute toxicity of death camas and low larkspur in cattle.

    Lumpy skin disease is of significant economic impact for the cattle industry in Africa. The disease is currently spreading aggressively in the Near East, posing a threat of incursion to Europe and Asia. Due to cross-protection within the Capripoxvirus genus, sheep pox virus (SPPV) vaccines have been widely used for cattle against lumpy skin disease virus (LSDV). In the Middle East and the Horn of Africa these vaccines have been associated with incomplete protection and adverse reactions in cattle post-vaccination. The present study confirms that the real identity of the commonly used Kenyan sheep and goat pox vaccine virus (KSGP) O-240 is not SPPV but is actually LSDV. The low level attenuation of this virus is likely to be not sufficient for safe use in cattle, causing clinical disease in vaccinated animals. In addition, Isiolo and Kedong goat pox strains, capable of infecting sheep, goats and cattle are identified for potential use as broad-spectrum vaccine candidates against all capripox diseases.

    Red deer can be infected with some gastrointestinal nematodes (GIN) of cattle but it is unknown to what extent. An indoor study was conducted to determine the establishment rate of cattle GIN in young deer. Five young calves and 5 young red deer were used. They were effectively treated with anthelmintics when housed and then infected 2 weeks later. After four weeks they were killed for total worm counts. Establishment rates were assessed comparing worm counts to the infective dose which were identified morphologically, and to the relative establishment rate of different species. The establishment rates (%) in cattle and deer respectively were H. contortus (8.0, 18.7, p=0.18), Ostertagia ostertagi (30.8, 0.7, p98%) of Trichostrongylus spp. were Trichostrongylus axei in both hosts and there were no differences between hosts for this species (p=0.11). In cattle >98% of Cooperia were Cooperia oncophora and the mean burden was much higher than in deer (pcattle (pcattle-origin GIN can establish in red deer. In particular, the establishment of H. contortus and T. axei could allow sufficient burdens to build up to be clinically significant. Importantly, almost no cattle Ostertagia species or small intestinal species established in deer. Copyright © 2017 Elsevier B.V. All rights reserved.

    This study was performed to clarify whether a formula (Holstein equation) based on a single blood sample and the isotonic, nonionic, iodine contrast medium iodixanol in Holstein dairy cows can apply to the estimation of glomerular filtration rate (GFR) for beef cattle. To verify the application of iodixanol in beef cattle, instead of the standard tracer inulin, both agents were coadministered as a bolus intravenous injection to identical animals at doses of 10 mg of I/kg of BW and 30 mg/kg. Blood was collected 30, 60, 90, and 120 min after the injection, and the GFR was determined by the conventional multisample strategies. The GFR values from iodixanol were well consistent with those from inulin, and no effects of BW, age, or parity on GFR estimates were noted. However, the GFR in cattle weighing less than 300 kg, aged<1 yr old, largely fluctuated, presumably due to the rapid ruminal growth and dynamic changes in renal function at young adult ages. Using clinically healthy cattle and those with renal failure, the GFR values estimated from the Holstein equation were in good agreement with those by the multisample method using iodixanol (r=0.89, P=0.01). The results indicate that the simplified Holstein equation using iodixanol can be used for estimating the GFR of beef cattle in the same dose regimen as Holstein dairy cows, and provides a practical and ethical alternative.

    Full Text Available The acceleration program to meet beef self sufficient in 2010 is expected to increase animal protein consumption of Indonesian people in order to be equal with other countries as well as to improve the livestock farmer’s income. The main objective of the program is to increase cattle population. Since the availability of forage and grassland is limited, beef cattle development is driven to the crop and plantation integration approach by using their by-product as cattle feed. Crop and plantation by-products, generally are considered to be fiber source with high lignocellulose’s and low nutritive value. Feeding high fiber would increase methane gas production, and faeces and grass cultivation also contributed on greenhouse emission. Methane is one of the main greenhouse gases contributed by agriculture sector; increasing beef cattle population using high fiber feed is predicted to increase methane production. Good management is expected to improve productivity and to reduce methane production on livestock. Some efforts could be done such as good feeding management and nutrition manipulation, environment friendly cattle waste management, improving management on roughage cultivation, and improving management on cattle production.

Assessments were done in Sumenep District and Pamekasan District, East Java. According to the body measurements, Madura cattle can be classified as a small to medium type with withers height of about 120 cm. Because of potential productivity in the limitation of environmental resources, Madura cattle can be classified as a "superior" cattle . Body measurements of Madura cattle in the present study were relatively the same with those of 50 years ago, indicating that there is no breeding improvement activities except natural selection . The variability of body measurements is relatively narrow . Improving productivity by outbreeding is needed . To conserve the unique germ plasm of the Indonesian genotype, such as Madura cattle and a possibility to improve their productivity by a complete prevention of cross breeding in the Madura islands needs further evaluation .

    In Algeria, the epidemiology of cattle abortions is not well understood. Therefore, the present study aims to estimate the prevalence of abortion in 75 Algerian cattle herds and correlate its possible association with brucellosis positivity and some managerial risk factors. The cattle abortion herd prevalence was 41.33% [95% CI 30.16-52.5%]. As for brucellosis, the serological evidence of brucellosis exposure was observed in 9 out of 75 herds accounting for 12% [95% CI 4.65-19.35] herd seroprevalence. The risk factor analysis using the univariable analysis followed by multivariable logistic regression did confirm that brucellosis positivity (OR = 5.19), mixed herd (OR = 2.5), contact with other herd (OR = 2.91), presence of dog in the herd (OR = 2.89), imported cattle (OR = 1.91), and farmers with less than 2 years' experience (OR = 2.69) as risk factors for abortion in Algerian cattle herds. Targeting these factors using a comprehensive control measure is needed to improve animal welfare and reduce economic losses associated with abortion in dairy cattle.

    In this paper, we report on the effects of a diet containing cloned-cattle meat on the reproductive parameters in pregnant rabbits. The artificially inseminated rabbits (gestation day 0) were fed a diet containing 5% or 10% of normal or cloned-cattle meat during the gestation period. Rabbits fed commercial pellet (no additional supplementations) were used as the control. Supplementation of cloned-cattle meat diets did not have any toxicologically significant effects on reproductive performance in dams (body weight, clinical signs, organ weight, and cesarean section analysis). And it also did not affect on fetal development (body and placental weight, and external, visceral and skeletal findings) compared to the controls. The only difference was a food consumption in the first week of gestation for all meat-based diet groups (pmeat. Copyright (c) 2010 Elsevier Ltd. All rights reserved.

    2016-12-01

    Full Text Available It has been argued that a country such as Liberia, not fully recovered from the devastation of decades of civil unrest, lacked the appropriate ethical and regulatory framework, basic human and health care services, and infrastructure to carry out clinical trials according to international standards of quality during a public health emergency. However, as Liberia, Sierra Leone, and Guinea were being ravaged by the largest and most devastating Ebola Virus Disease (EVD outbreak ever recorded, the topic of conducting clinical trials of experimental vaccine and treatment candidates in these resource-poor countries generated the keen interest and concern of scientists, researchers, physicians, bioethicists, philanthropists, and even politicians. Decisive action on behalf of the Liberian government, and a timely positive and supportive response from the United States (U.S. government, led to the formation of PREVAIL (Partnership for Research on Ebola Vaccines in Liberia – a clinical research partnership between the two governments. Within a span of 12 weeks, this partnership accomplished the unimaginable: the successful initiation of a Phase II/III vaccine clinical trial for EVD in Liberia. This paper will discuss the dynamics of the research collaboration, barriers encountered, breakthroughs realized, key elements of success, and lessons learned in the process.

    Purpose: We report our results using MRT for clinical stage I-II HD and assess the value of published prognostic criteria in our study population. Pts and Methods: Between 1969 and 1994, 261 pts were treated with MRT alone for clinical stage I-II supradiaphragmatic HD. Pt characteristics: median age-30; M-54%/F-46%; stage IA-52%, IB-2%, IIA-37%, IIB-8%; histology LP-21%, NS-51%, MC-23%, other 5%; median ESR 18. CT abdomen and LAG were performed in 61% and 60% respectively. No pt had prior staging laparotomy. No pt received infradiaphragmatic RT. Central axis dose was 32 Gy-36 Gy. Univariate analysis was performed for prognostic factors for progression-free (PFS) and overall survival(OS). Outcome was assessed in favourable subsets as defined by: EORTC (v. favourable: CSIA, LP or NS histology, age < 40, female, no bulk, ESR < 50; favourable: CSI-II, age < 50, < 4 sites, no bulky mediastinal mass, ESR < 50 with no B symptoms or ESR < 30 with B symptoms); Princess Margaret Hospital (PMH) (IA-IIA, LP or NS histology, ESR < 40, age < 50, no large mediastinal mass, no E lesion). Results: 261 pts completed RT, with 5% requiring treatment interruption for toxicity. Significant factors (P<0.05) for PFS were stage, performance status, histology, B symptoms, number of sites, ESR and bulk. Significant factors (P<0.05) for OS were age, performance status, histology and B symptoms. (The results of a multivariate analysis will be presented.) Results in our study population using published prognostic criteria (in %): Thirty-six percent progressed following RT: 8% in-field; 24% out of field only (including 10% in the paraaortic/splenic region alone); 4% marginal; Fifty-seven percent of relapsed pts remain progression free after subsequent salvage treatment. Two cases of acute leukaemia, 8 cases of non-Hodgkin's lymphoma and 14 (non-skin) carcinomas occurred, of which 11 were in-field. Seventy pts have died. The cause was: HD 41%; other malignancy 20%; cardiovascular 17%; other 15

    Labral repair and biceps tenodesis are routine operations for superior labrum anterior posterior (SLAP) lesion of the shoulder, but evidence of their efficacy is lacking. We evaluated the effect of labral repair, biceps tenodesis and sham surgery on SLAP lesions. A double-blind, sham-controlled trial was conducted with 118 surgical candidates (mean age 40 years), with patient history, clinical symptoms and MRI arthrography indicating an isolated type II SLAP lesion. Patients were randomly assigned to either labral repair (n=40), biceps tenodesis (n=39) or sham surgery (n=39) if arthroscopy revealed an isolated SLAP II lesion. Primary outcomes at 6 and 24 months were clinical Rowe score ranging from 0 to 100 (best possible) and Western Ontario Shoulder Instability Index (WOSI) ranging from 0 (best possible) to 2100. Secondary outcomes were Oxford Instability Shoulder Score, change in main symptoms, EuroQol (EQ-5D and EQ-VAS), patient satisfaction and complications. There were no significant between-group differences at any follow-up in any outcome. Between-group differences in Rowe scores at 2 years were: biceps tenodesis versus labral repair: 1.0 (95% CI -5.4 to 7.4), p=0.76; biceps tenodesis versus sham surgery: 1.6 (95% CI -5.0 to 8.1), p=0.64; and labral repair versus sham surgery: 0.6 (95% CI -5.9 to 7.0), p=0.86. Similar results-no differences between groups-were found for WOSI scores. Postoperative stiffness occurred in five patients after labral repair and in four patients after tenodesis. Neither labral repair nor biceps tenodesis had any significant clinical benefit over sham surgery for patients with SLAP II lesions in the population studied.

    This article is the second part of a two-part series reporting a study of the role of the Clinical Librarian (CL) in the UK. A qualitative method of semi-structured interviews was used to explore in-depth the role of the CL. The interviews provided a rich source of data and give insight into this new and emerging role as practised in the National Health Service (NHS). Similarities and differences are examined between the CL population and reported within themes, specifically: personal qualities and skills required, training for the CLs, marketing the CL service, working in the clinical environment, monitoring and evaluation and the acceptance of the CL in the NHS. A common understanding of the skills and knowledge required to undertake the CL role was shared by the respondents. However, practice differed as this was often dictated by local circumstances. The study confirmed the need for the CLs to work with clinical colleagues in the clinical setting to enhance patient care. The importance of using best evidence to support patient care is a message that is slowly becoming the norm in the NHS and the CL role in this practice is demonstrated by this study.

    Full Text Available Biological and some clinical evidence suggest that high-dose intravenous vitamin C (IVC could increase the effectiveness of cancer chemotherapy. IVC is widely used by integrative and complementary cancer therapists, but rigorous data are lacking as to its safety and which cancers and chemotherapy regimens would be the most promising to investigate in detail.We carried out a phase I-II safety, tolerability, pharmacokinetic and efficacy trial of IVC combined with chemotherapy in patients whose treating oncologist judged that standard-of-care or off-label chemotherapy offered less than a 33% likelihood of a meaningful response. We documented adverse events and toxicity associated with IVC infusions, determined pre- and post-chemotherapy vitamin C and oxalic acid pharmacokinetic profiles, and monitored objective clinical responses, mood and quality of life. Fourteen patients were enrolled. IVC was safe and generally well tolerated, although some patients experienced transient adverse events during or after IVC infusions. The pre- and post-chemotherapy pharmacokinetic profiles suggested that tissue uptake of vitamin C increases after chemotherapy, with no increase in urinary oxalic acid excretion. Three patients with different types of cancer experienced unexpected transient stable disease, increased energy and functional improvement.Despite IVC's biological and clinical plausibility, career cancer investigators currently ignore it while integrative cancer therapists use it widely but without reporting the kind of clinical data that is normally gathered in cancer drug development. The present study neither proves nor disproves IVC's value in cancer therapy, but it provides practical information, and indicates a feasible way to evaluate this plausible but unproven therapy in an academic environment that is currently uninterested in it. If carried out in sufficient numbers, simple studies like this one could identify specific clusters of cancer type

    Buruli ulcer (BU) is a necrotizing skin disease most prevalent among West African children. The causative organism, Mycobacterium ulcerans, is sensitive to temperatures above 37°C. We investigated the safety and efficacy of a local heat application device based on phase change material. In a phase II open label single center noncomparative clinical trial (ISRCTN 72102977) under GCP standards in Cameroon, laboratory confirmed BU patients received up to 8 weeks of heat treatment. We assessed efficacy based on the endpoints 'absence of clinical BU specific features' or 'wound closure' within 6 months ("primary cure"), and 'absence of clinical recurrence within 24 month' ("definite cure"). Of 53 patients 51 (96%) had ulcerative disease. 62% were classified as World Health Organization category II, 19% each as category I and III. The average lesion size was 45 cm(2). Within 6 months after completion of heat treatment 92.4% (49 of 53, 95% confidence interval [CI], 81.8% to 98.0%) achieved cure of their primary lesion. At 24 months follow-up 83.7% (41 of 49, 95% CI, 70.3% to 92.7%) of patients with primary cure remained free of recurrence. Heat treatment was well tolerated; adverse effects were occasional mild local skin reactions. Local thermotherapy is a highly effective, simple, cheap and safe treatment for M. ulcerans disease. It has in particular potential as home-based remedy for BU suspicious lesions at community level where laboratory confirmation is not available. ISRCT 72102977. © The Author 2015.

    To summarize results of a Clinical Practice Statement on radiation therapy for stage II-III rectal cancer, which addressed appropriate customization of (neo)adjuvant radiation therapy and use of non-surgical therapy for patients who are inoperable or refuse abdominoperineal resection. The RAND/University of California, Los Angeles, Appropriateness Method was applied to combine current evidence with multidisciplinary expert opinion. A systematic literature review was conducted and used by the expert panel to rate appropriateness of radiation therapy options for different clinical scenarios. Treatments were categorized by median rating as Appropriate, May Be Appropriate, or Rarely Appropriate. In the neoadjuvant setting, chemoradiation was rated Appropriate and the ratings indicated short-course radiation therapy, chemotherapy alone, and no neoadjuvant therapy are potential options in selected patients. However, neoadjuvant endorectal brachytherapy was rated Rarely Appropriate. For adjuvant therapy, chemoradiation (plus ≥4 months of chemotherapy) was rated Appropriate and chemotherapy alone May Be Appropriate for most scenarios. For medically inoperable patients, definitive external beam radiation therapy and chemotherapy alone were rated May Be Appropriate, whereas endorectal brachytherapy and chemoradiation plus endorectal brachytherapy were possible approaches for some scenarios. The last option, definitive chemoradiation, was rated Appropriate to May Be Appropriate based on performance status. Finally, for patients with low-lying tumors refusing abdominoperineal resection, definitive chemoradiation alone, chemoradiation plus endorectal brachytherapy, and chemoradiation plus external beam radiation therapy were all rated Appropriate. This Clinical Practice Statement demonstrated the central role of radiation therapy in stage II-III rectal cancer management and evaluated ways to better individualize its use in the neoadjuvant, adjuvant, and definitive settings

    Objective Treatment of furcation defects are thought to be challenging. The purpose of this study was to evaluate the clinical and radiographic parameters of Bio-Gen with Biocollagen compared with Bio-Gen with connective tissue in the treatment of Class II furcation defects. Material and Methods In this clinical trial, 24 patients with Class II furcation defect on a buccal or lingual mandibular molar were recruited. After oral hygiene instruction, scaling and root planing and achievement of acceptable plaque control, the patients were randomly chosen to receive either connective tissue and Bio-Gen (case group) or Biocollagen and Bio-Gen (control group). The following parameters were recorded before the first and re-entry surgery (six months later): vertical clinical attachment level (VCAL), gingival index (GI), plaque index (PI), horizontal probing depth (HPD), vertical probing depth (VPD), gingival recession (GR), furcation vertical component (FVC), furcation to alveolar crest (FAC), fornix to base of defect (FBD), and furcation horizontal component (FHC) were calculated at the time of first surgery and during re-entry. A digital periapical radiograph was taken in parallel before first surgery and re-entry. The radiographs were then analyzed by digital subtraction. The differences with p value <0.05 were considered significant. Results Only the mean changes of FAC, FHC, mean of FHC, FBD in re-entry revealed statistically significant differences between the two groups. HPD, VPD, FBD, FAC, and FHC showed statistically significant differences after 6 months in the case group. However, in the control group, statistically significant differences were found in GR and HPD. We did not observe any significant difference in radiographic changes among the two groups. Conclusion The results of this trial indicate that better clinical outcomes can be obtained with connective tissue grafts in combination with bone material compared with a resorbable barrier with bone material

    Felipe Peixoto de Arruda

    Full Text Available ABSTRACT: In Brazil sodium monofluoroacetate (MFA containing plants are represented by 16 species that belong to three principle genera: Palicourea ( Rubiaceae , Amorimia ( Malpighiaceae , and Tanaecium ( Bignoniaceae . These plants can cause acute cardiac failure often referred to as sudden death syndrome. The objective of this paper was to determine if N. stannea contains MFA and to report the clinical signs and pathology of cattle experimentally poisoned by this plant. MFA was detected in all N. stannea plant parts except mature leaves. Niedenzuella stannea was dosed to cattle at single doses of 15-30g kg-1 bw. Clinical signs and pathology observed were similar to those reported by other MFA-containing plants. Animals showed marked tachycardia, labored breathing, muscle tremors, loss of balance, ataxia, falling, recumbence, pedaling movements, and opisthotonous leading to death in few minutes. Gross lesions included engorgement of the large veins, severe lung edema, and petechiae , ecchymosis and suffusions in the pericardium, epicardium and pleura. Histologically, hydropic vacuolar degeneration and necrosis of epithelial cells of the kidney were observed. Cattle that received daily doses of 4g kg-1 body weight for 24 days showed no clinical signs. In summary, this is the first report that N. stannea contains monofluoroacetate and causes sudden death in cattle.

    Full Text Available Malignant catarrhal fever (MCF is a fatal disease especially affecting cattle and buffaloes. A study on the serial blood transmission of MCF was conducted by injecting whole blood of MCF animals into 9 experimental animals. Diagnosis of MCF was based on the clinico-pathological fmdings and polymerase chain reaction (PCR test. The disease has successfully, been achieved in six animals of three Bali cattle and three buffaloes but not in a Bali-cross breed and two Bos indicus (Ongole cattle. Wide range of clinical signs and gross-pathological features were observed. The study showed the degree of susceptibility of experimental animals: Bali cattle and buffalo were highly susceptible (3 out of 3 affected with MCF, Bali-cross breed and Bos indicus (Ongole cattle seemed not susceptible to whole blood experimental transmission. It shows that when Bali cattle acted as inoculum donor, buffalo tended to be clinically more severe than Bali cattle. On the other hand, when buffalo acted as inoculum donor, Bali cattle suffered from MCF more severe than buffalo. The diagnosis of MCF by histopathological examination and the PCR test bad positive correlation (100% in the first experiment, while in the second experiment the PCR test tends to be more sensitive. Based on the restriction endonuclease (RE test, the MCF causal agent in this study appeared to be genetically similar in each case. It is concluded that the serial experimental transmission of MCF by means of whole blood inoculation has been successfully achieved in Bali cattle and buffalo but not in Bali-cross breed and Ongole cattle, and there is a positive correlation between the PCR test and histopathological examination with the PCR test tends to be more sensitive.

    A survey of cattle dip facilities and current practices employed was done. Coumaphos and ethion were the commonly used acaricides in the four respondent stock farms. The behavior of coumaphos in a simulated model cattle dip was monitored using radiotracer techniques. Degradation was rapid, resulting in the formation of potasan metabolite and bound residues in the sediment. A rapid field method for the detection of organophosphate pesticides was used in monitoring the degradation of coumaphos in a cattle dip. The sensitivity of the method is comparable to the conventional HPLC method employed. This rapid field method can easily be used by cattle ranch owners to monitor coumaphos content of the vat facility so that recharging could be made in order to prevent the onset of resistance development in cattle tick.

    Objective To harmonize the collection of nonsurgical clinical and epidemiologic data relevant to endometriosis research, allowing large-scale collaboration. Design An international collaboration involving 34 clinical/academic centers and three industry collaborators from 16 countries on five continents. Setting In 2013, two workshops followed by global consultation, bringing together 54 leaders in endometriosis research. Patients None. Intervention(s) Development of a self-administered endometriosis patient questionnaire (EPQ), based on [1] systematic comparison of questionnaires from eight centers that collect data from endometriosis cases (and controls/comparison women) on a medium to large scale (publication on >100 cases); [2] literature evidence; and [3] several global consultation rounds. Main Outcome Measure(s) Standard recommended and minimum required questionnaires to capture detailed clinical and covariate data. Result(s) The standard recommended (EPHect EPQ-S) and minimum required (EPHect EPQ-M) questionnaires contain questions on pelvic pain, subfertility and menstrual/reproductive history, hormone/medication use, medical history, and personal information. Conclusion(s) The EPQ captures the basic set of patient characteristics and exposures considered by the WERF EPHect Working Group to be most critical for the advancement of endometriosis research, but is also relevant to other female conditions with similar risk factors and/or symptomatology. The instruments will be reviewed based on feedback from investigators, and–after a first review after 1 year–triannually through systematic follow-up surveys.

    The recently sequenced cattle (Bos taurus) genome unraveled the unique genomic features of the species and provided the molecular basis for applying a systemic approach to systematically link genomic information to metabolic traits. Comparative analysis has identified a variety of evolutionary adaptive features in the cattle genome, such as an expansion of the gene families related to the rumen function, large number of chromosomal rearrangements affecting regulation of genes for lactation, and chromosomal rearrangements that are associated with segmental duplications and copy number variations. Metabolic reconstruction of the cattle genome has revealed that core metabolic pathways are highly conserved among mammals although five metabolic genes are deleted or highly diverged and seven metabolic genes are present in duplicate in the cattle genome compared to their human counter parts. The evolutionary loss and gain of metabolic genes in the cattle genome may reflect metabolic adaptations of cattle. Metabolic reconstruction also provides a platform for better understanding of metabolic regulation in cattle and ruminants. A substantial body of transcriptomics data from dairy and beef cattle under different nutritional management and across different stages of growth and lactation are already available and will aid in linking the genome with metabolism and nutritional physiology of cattle. Application of cattle genomics has great potential for future development of nutritional strategies to improve efficiency and sustainability of beef and milk production. One of the biggest challenges is to integrate genomic and phenotypic data and interpret them in a biological and practical platform. Systems biology, a holistic and systemic approach, will be very useful in overcoming this challenge.

    The objective of this randomized noninferiority clinical trial was to compare the effect of treatment with 3 different dry cow therapy formulations at dry-off on cow-level health and production parameters in the first 100 d in milk (DIM) in the subsequent lactation, including 305-d mature-equivalent (305 ME) milk production, linear score (LS), risk for the cow experiencing a clinical mastitis event, risk for culling or death, and risk for pregnancy by 100 DIM. A total of 1,091 cows from 6 commercial dairy herds in 4 states (California, Iowa, Minnesota, and Wisconsin) were randomly assigned at dry-off to receive treatment with 1 of 3 commercial products: Quartermaster (QT; Zoetis Animal Health, Madison, NJ), Spectramast DC (SP; Zoetis Animal Health) or ToMorrow Dry Cow (TM; Boehringer Ingelheim Vetmedica Inc., St Joseph, MO). All clinical mastitis, pregnancy, culling, and death events occurring in the first 100 DIM were recorded by farm staff using an on-farm electronic record-keeping system. Dairy Herd Improvement Association test-day records of milk production and milk component testing were retrieved electronically. Mixed linear regression analysis was used to describe the effect of treatment on 305ME milk production and LS recorded on the last Dairy Herd Improvement Association test day before 100 DIM. Cox proportional hazards regression analysis was used to describe the effect of treatment on risk for experiencing a case of clinical mastitis, risk for leaving the herd, and risk for pregnancy between calving and 100 DIM. Results showed no effect of treatment on adjusted mean 305 ME milk production (QT=11,759 kg, SP=11,574 kg, and TM=11,761 kg) or adjusted mean LS (QT=1.8, SP=1.9, and TM=1.6) on the last test day before 100 DIM. Similarly, no effect of treatment was observed on risk for a clinical mastitis event (QT=14.8%, SP=12.7%, and TM=15.0%), risk for leaving the herd (QT=7.5%, SP=9.2%, and TM=10.3%), or risk for pregnancy (QT=31.5%, SP=26.1%, and TM=26

    High-grade chondrosarcoma, high-grade glioma and intrahepatic cholangiocarcinoma are aggressive types of cancer with a dismal outcome. This is due to the lack of effective treatment options, emphasising the need for novel therapies. Mutations in the genes IDH1 and IDH2 (isocitrate dehydrogenase 1 and 2) occur in 60% of chondrosarcoma, 80% of WHO grade II-IV glioma and 20% of intrahepatic cholangiocarcinoma. IDH1/2 -mutated cancer cells produce the oncometabolite D -2-hydroxyglutarate ( D -2HG) and are metabolically vulnerable to treatment with the oral antidiabetic metformin and the oral antimalarial drug chloroquine. We describe a dose-finding phase Ib/II clinical trial, in which patients with IDH1/2 -mutated chondrosarcoma, glioma and intrahepatic cholangiocarcinoma are treated with a combination of metformin and chloroquine. Dose escalation is performed according to a 3+3 dose-escalation scheme. The primary objective is to determine the maximum tolerated dose to establish the recommended dose for a phase II clinical trial. Secondary objectives of the study include (1) determination of pharmacokinetics and toxic effects of the study therapy, for which metformin and chloroquine serum levels will be determined over time; (2) investigation of tumour responses to metformin plus chloroquine in IDH1/2 -mutated cancers using CT/MRI scans; and (3) whether tumour responses can be measured by non-invasive D -2HG measurements (mass spectrometry and magnetic resonance spectroscopy) of tumour tissue, serum, urine, and/or bile or next-generation sequencing of circulating tumour DNA (liquid biopsies). This study may open a novel treatment avenue for IDH1/2 -mutated high-grade chondrosarcoma, glioma and intrahepatic cholangiocarcinoma by repurposing the combination of two inexpensive drugs that are already approved for other indications. This study has been approved by the medical-ethical review committee of the Academic Medical Center, Amsterdam, The Netherlands. The report

    Despite promising preliminary results in treating fibromyalgia (FM) pain, no neuromodulation technique has been adopted in clinical practice because of limited efficacy, low response rate, or poor tolerability. This phase II open-label trial aims to define a methodology for a clinically effective treatment of pain in FM by establishing treatment protocols and screening procedures to maximize efficacy and response rate. High-definition transcranial direct current stimulation (HD-tDCS) provides targeted subthreshold brain stimulation, combining tolerability with specificity. We aimed to establish the number of HD-tDCS sessions required to achieve a 50% FM pain reduction, and to characterize the biometrics of the response, including brain network activation pain scores of contact heat-evoked potentials. We report a clinically significant benefit of a 50% pain reduction in half (n = 7) of the patients (N = 14), with responders and nonresponders alike benefiting from a cumulative effect of treatment, reflected in significant pain reduction (P = .035) as well as improved quality of life (P = .001) over time. We also report an aggregate 6-week response rate of 50% of patients and estimate 15 as the median number of HD-tDCS sessions to reach clinically meaningful outcomes. The methodology for a pivotal FM neuromodulation clinical trial with individualized treatment is thus supported. Registered in Clinicaltrials.gov under registry number NCT01842009. In this article, an optimized protocol for the treatment of fibromyalgia pain with targeted subthreshold brain stimulation using high-definition transcranial direct current stimulation is outlined.

    Present study was undertaken to determine the seroprevalence of brucellosis in cattle of Pabna and Mymensingh districts in Bangladesh. A total of 260 cattle sera samples were collected from Pahna and Mymensingh districts. The epidemiological data were collected by structured questionnaire. RBT and SAT were used as screening tests and further confirmed by 1-ELISA. The seroprevalence of Bruce/Ia ill cattle was estimated to be 4.23%, 3.07% and 2.31% by RBT, SAT and 1-ELISA, respectively. The comparison of the serological tests result revealed the highest prevalence in RBT than SAT and 1-EL ISA. The prevalence of Brucella was 2.5% in Pabna and 2.14% in Mymensingh. It was observed that, a higher prevalence of Bruce/la was found in female (2.67%) than in male (1.82%), natural breeding (2.67%) than artificial breeding (1.81%), in aged animals (3.33%) than young (1.25 degree percent). But these differences were not statistically significant. There exists significant difference between prevalence of Bruce/II in cattle with history of abortion than without history of abortion (P value=0.013). (author)

    The Vitek 2 Anaerobe and Corynebacterium Identification Card (ANC) was recently evaluated in a multicentre study. In the present work, this system was compared with the BBL Crystal Anaerobe and RapID ANA II panels. These kits were tested using 196 strains of anaerobes that had been previously identified by gas-liquid chromatography. Identification to the species or to the genus level was 75.0%, 81.1% and 70.9% for Crystal, RapID and Vitek, respectively. Vitek ANC failed to provide any identification in 20.4% of the strains, but it had fewer misidentifications than RapID. The confidence factors provided on the results report of each kit were not always correlated with a lower risk of major errors, with the exception of Vitek 2 in which a confidence factor higher than 0.86 excluded the risk of misidentification in more than 87% of isolates. The lower rate of identification by the Vitek and Crystal panels is mostly due the lower ability of these systems to identify the Clostridia. Overall, the three panels are comparable but need improvement to a better accuracy. Copyright (c) 2010 Elsevier Ltd. All rights reserved.

    This article provides information and a commentary on trials presented at the American Heart Association meeting held in November 2005, relevant to the pathophysiology, prevention and treatment of heart failure. All reports should be considered as preliminary data, as analyses may change in the final publication. In REPAIR-AMI an improvement in ejection fraction was observed in post-MI patients following infusion of bone marrow stem cells. However, the ASTAMI study showed no benefit of stem cell implantation in a similar patient cohort. The JELIS study reported a reduction in major coronary events in patients receiving statins plus fish oil compared to statins alone. MEGA showed that low dose statins in a low risk population reduce the incidence of major cardiovascular events. Two studies of levosimendan in acute heart failure gave conflicting results, in the REVIVE-II study levosimendan was reported to have a superior effect on the composite primary outcome compared to placebo, however, in SURVIVE despite a trend to early benefit with levosimendan, there was no difference in effect on long-term outcome versus dobutamine. The PROACTIVE study showed encouraging results for the use of pioglitazone in post-myocardial infarction patients with concomitant type 2 diabetes.

    Pregnancy in women with autoimmune rheumatic diseases is associated with several maternal and fetal complications. The development of clinical practice guidelines with the best available scientific evidence may help standardize the care of these patients. To provide recommendations regarding prenatal care, treatment, and a more effective monitoring of pregnancy in women with lupus erythematosus, rheumatoid arthritis (RA) and antiphospholipid syndrome (APS). Nominal panels were formed for consensus, systematic search of information, development of clinical questions, processing and staging of recommendations, internal validation by peers and external validation of the final document. The quality criteria of the AGREE II instrument were followed. The panels answered 37 questions related to maternal and fetal care in lupus erythematosus, RA and APS, as well as for use of antirheumatic drugs during pregnancy and lactation. The recommendations were discussed and integrated into a final manuscript. Finally, the corresponding algorithms were developed. In this second part, the recommendations for pregnant women with RA, APS and the use of antirheumatic drugs during pregnancy and lactation are presented. We believe that the Mexican clinical practice guidelines for the management of pregnancy in women with RA and APS integrate the best available evidence for the treatment and follow-up of patients with these conditions.

    Whilst Clinical Practice Guidelines (CPGs) are used for the development of local protocols in kidney transplantation (Ktx), the quality of their methodology is variable. This systematic review aimed to critically appraise international CPGs in all aspects of Ktx using the Appraisal of Guidelines for Research and Evaluation (AGREE) II tool. CPGs in Ktx and donation published between 2010 and 2017 were identified from MEDLINE, Embase, National Guideline Clearinghouse, NHS and NICE Evidence Searches, and the websites of transplant societies. Using AGREE II, 3 appraisers assessed the quality of CPGs. Interrater reliability was measured using the intraclass correlation coefficient (ICC). Searches identified 3,168 records and 115 CPGs were included. The highest scoring AGREE II domain was 'Scope and Purpose' (80%; Range 30-100%), followed by 'Clarity of Presentation' (77%; Range 43-98%), 'Editorial independence' (52%; Range 0-94%), 'Rigour of Development' (47%; Range 6-97%) and 'Stakeholder Involvement' (41%; Range 11-85%). The poorest scoring domain was 'Applicability' (31%; Range 3-74%). Most CPGs were recommended for future use either with (63%) or without modifications (18%). A small number were not recommended for future use (14%) or reviewers did not agree on recommending the CPG (5%). The overall mean CPG quality score was 4 out of 7 (Range 2-7). The mean ICC of 0.74 indicated substantial agreement between reviewers. The quality of international CPGs in Ktx was variable, and most CPGs lacked key aspects of methodological robustness and transparency. Improvements in methodology, patient involvement and strategies for implementation are required.

    located in the state of Paraíba, northeastern Brazil. The epidemiology, clinical signs and pathology of the disease were studied from May 2005 to November 2006. T. vivax was identified morphologically and by polymerase chain reaction test (PCR. The affected cattle presented anorexia, depression, fever, anemia, weight loss, reduction in milk production, transitory blindness, abortion and some nervous signs as nystagmus, tetany and bruxism. All cattle that presented nervous signs died. Necropsy findings were enlarged lymph and spleen, serous atrophy of the fat depots, proeminence of the splenic white pulp, hydropericardium and pericardial petechiae and ecchymoses on the epicardium. Histologically there was meningoencephalitis. The treatment of the clinical cases with diminazena aceturate was efficient with clearance of the parasite from the blood or disappearance of clinical signs in up to 2 months after the beginning of the outbreak on the two farms studied. The epidemiologic factors favoring the occurrence of the outbreak were the abundance of mechanical vectors, as tabanids and Stomoxys sp., and the introduction into the herd of cattle from farms where the disease occurred. It is suggested that the semiarid of the Brazilian Northeast is an enzootic instability region for trypanosomiasis due to its prolonged periods of drought and high temperatures, constituting during most part of the year an unfavorable environment for the development of vectors.

    Current clinical guidelines recommend prescribing systemic antibiotic therapy (SAT) for patients having an avulsed permanent tooth replanted. The principles of evidence-based dentistry can be used to assess whether this is the best approach based on currently-available evidence. The objective of this study was to use the principles of evidence-based dentistry to answer the PICO question: (P) for a replanted avulsed permanent tooth, (I) is prescribing SAT, (C) compared with not prescribing SAT, (O) associated with an increased likelihood of successful periodontal healing after tooth replantation? A literature search was performed across four internet databases (Ovid Medline, Cochrane Library, PubMed, ISI Web of Science), for relevant citations (n = 35 702). Limiting citations to those in English and removing duplicates produced a set of titles (n = 14 742) that were sieved according to evidence-based dentistry principles. Relevant titles were selected for abstract assessment (n = 782), identifying papers for examination (n = 74). Inclusion criteria were applied and three papers (326 total teeth) met the final criteria for meta-analysis. Meta-analyses found no statistically significant difference between prescribing or not prescribing antibiotics for acceptable periodontal healing without progressive root resorption (common odds ratio = 0.90, SE = 0.29, 95% confidence intervals = 0.51-1.58). The evidence for an association between prescribing SAT and an increased likelihood of acceptable periodontal healing outcome is inconclusive. This investigation of antibiotic use as defined in the clinical guidelines indicates there is inconclusive clinical evidence from studies of replanted avulsed human teeth to either contradict or support the guideline. Pending future research to the contrary, dentists are recommended to follow current guidelines in prescribing SAT when replanting avulsed teeth.

  6. Greenhouse Gas Emissions From Cattle

    Directory of Open Access Journals (Sweden)

    2015-03-01

    Full Text Available Cattle produce greenhouse gases (GHG which lead to changes in the chemical composition of the atmosphere. These gases which cause greenhouse effect include: methane (CH4, nitrous oxide (N2O, nitrogen oxides (NOx, sulphur dioxide (SO2, ammonia (NH3, dust particles and non-methane volatile organic compounds, commonly described as other than methane hydrocarbons. Fermentation processes taking place in the digestive tract produce ‘digestive gases’, distinguished from gases which are emitted during the decomposition of manure. Among these digestive gases methane and non-methane volatile organic compounds are of particular relevance importance. The amount of gases produced by cows can be reduced by choosing to rear animals with an improved genetically based performance. A dairy cow with higher production efficiency, producing milk with higher protein content and at the same time reduced fat content emits less GHG into the environment. Increasing the ratio of feed mixtures in a feed ration also reduces GHG emissions, especially of methane. By selection of dairy cows with higher production efficiency and appropriate nutrition, the farm's expected milk production target can be achieved while at the same time, the size of the herd is reduced, leading to a reduction of GHG emissions.

    Over the past few years an irradiation and measuring system has been developed for the reactor BER II at the Hahn-Meitner-Institute. It was to be suited in particular to the neutron activation analysis of biological material via short lived radionuclides. The general characteristics of this equipment and some experimental details as the recycling facility and the device used for measuring the irradiation time, the waiting time and the neutron fluency are described. This equipment was used to determine physiological concentrations of the elements sodium, chlorine, aluminium, phosphorus, fluorine, calcium, copper and selenium in biological material. The results have been compared with those obtained by photon activation analysis or ion sensitive electrode. As an example of the application of the apparatus the authors report on the clinical analysis of Ca, F, P and Al in the control of the treatment of patients suffering from osteoporosis. (author)

    Full Text Available The relevance. Microelementosis (imbalance of certain microelements in the body, ME is considered as one of the most important clinical and pathogenetic components of degenerative and inflammatory joint diseases. ME can play the role of co-factors involved in the processes of articular inflammation. Objective. To study the levels in the hair and to assess the clinical and pathogenetic significance of osteoassociated ME (cobalt — Co, copper — Cu, iron — Fe, lithium — Li, manganese — Mn, lead — Pb, strontium — Sr, zinc — Zn at a variety of arthritis — rheumatoid (RA, chlamydia-induced (ReA, psoriatic (PsA, gouty (PA and osteoarthritis (OA. Material and methods. There were 262 patients under observation, among them 89 persons suffered from RA, 31 — ReA, 35 — PsA, 49 — GA and 58 — OA. The distribution of males and females in these groups was 1 : 2, 2 : 1, 1 : 1, 11 : 1, 1 : 3, respectively, the average age of the patients was 47, 34, 42, 48 and 58 years old, while the duration of clinical manifestations of disease was 10, 4, 11, 7 and 12 years. ME in the hair was examined by atomic absorption spectrometer with electrographite atomizer «SolAAr-Mk2-MOZe». Results. All patients with arthritis are prone to have microelementosis in hair. All nosological forms of joint pathology are associated with a significant decrease of Mn level in hair, when the level of Pb and Fe accumulated. Only RA was characterized by the absence of changes in the hair level of Co, PsA — of Cu, PA — Li and Sr. If, in comparison with healthy persons, the PA proceeds with an increased concentration level of Zn in the hair, the OA is characterized by an increased level of ME, that has a certain differential diagnostic value. There is either direct relationship between the hair and blood serum indexes (Mn, Pb or multi-directional (Fe ones. Microelement blood composition depends on the activity level, clinical and laboratory signs of disease, the

    To quantify the radiographic parameters of the caudal vena cava (CVC) in healthy cattle and demonstrate their clinical usefulness, the present study compared the ratios of the diameter of the thoracic CVC to the diameter of the aorta (Ao) and length of the thoracic vertebrae (VL), which are all positioned in the same intercostal space, in 81 healthy control cattle (43 growing, 38 adult) and 10 cattle with heart disease. The average diameter of the CVC (CVCave) was correlated with the size of the Ao and VL in the control cows. Although the diameter and pulsation index of the CVC differed significantly between the growing and adult cows, the ratios of CVC/Ao and CVC/VL were fixed values for both the growing and mature cattle. However, in the cattle with heart disease, the pulsation index of the CVC was significantly lower or there was absence of pulsation due to a dilated CVC, and the ratio of CVCave/Ao and CVCave/VL were significantly higher than those in the healthy cattle

    Crossbred cattle are more prone to mastitis in comparison to indigenous cattle. Toll-like receptor 4 (TLR4) recognizes pathogen ligands, for example, lipopolysaccharide (LPS) endotoxin from Escherichia coli and mediates signaling to initiate innate and adaptive immune responses. Mutations in TLR4 can compromise the host immune response to certain pathogens, so it may be a potential candidate for marker assisted selection to enhance mastitis resistance in dairy cattle. Hence, in this study role of bovine TLR4 gene in mastitis resistance was investigated by association as well as expression profiling analysis in crossbred cattle. The animals were divided into mastitis affected and unaffected groups on the basis of history of animals and California Mastitis Test (CMT). PCR-SSCP and Sequence analysis revealed three genotypes of coreceptor binding region 1 (CRBR1) fragment of TLR4 gene namely AA, AB, and BB in both groups of cattle. The logistic regression model did not show any significant effect of these genotypes on the occurrence of clinical mastitis. Moreover, in vitro challenge of peripheral blood mononuclear cells (PBMCs) with LPS failed to show any association of the genotypes with TLR4 gene expression. In a nutshell, in the present study enough evidence was not found for association of the SNP variants of CRBR1 fragment of TLR4 gene with mastitis susceptibility in crossbred cattle.

    Vocal fold scar and sulcus are intractable diseases with no effective established treatments. Hepatocyte growth factor (HGF) has preclinically proven to have potent antifibrotic and regenerative effects on vocal fold scar. The current Phase I/II clinical trial aims to examine the safety and effectiveness of intracordal injection of a recombinant human HGF drug for patients with vocal fold scar or sulcus. This is an open-label, dose-escalating, first-in-human clinical trial. Eighteen patients with bilateral vocal fold scar or sulcus were enrolled and divided into three groups: Step I received 1 μg of HGF per vocal fold; Step II received 3 μg of HGF; and Step III received 10 μg of HGF. Injections were administered once weekly for 4 weeks. The protocol treatment was performed starting with Step I and escalating to Step III. Patients were followed for 6 months post-treatment. Local and systemic safety aspects were examined as primary endpoints, and therapeutic effects were assessed as secondary endpoints using voice handicap index-10; maximum phonation time; vocal fold vibratory amplitude; grade, rough, breathy, asthenic, strained scale; and jitter. The results indicated no serious drug-related adverse events in either the systemic or local examinations. In whole-subject analysis, voice handicap index-10, vocal fold vibratory amplitude, and grade, rough, breathy, asthenic, strained scale were significantly improved at 6 months, whereas maximum phonation time and jitter varied. There were no significant differences in phonatory data between the step groups. In conclusion, intracordal injection of a recombinant human HGF drug was safe, feasible, and potentially effective for human patients with vocal fold scar or sulcus.

    Type 2 diabetes mellitus (T2DM) is a worldwide and national public health problem that has a great impact on the population in Saudi Arabia. High-quality clinical practice guidelines (CPGs) are cornerstones in improving the health care provided for patients with diabetes. This study evaluated the methodological rigour, transparency, and applicability of recently published CPGs. Our group conducted a systematic search for recently published CPGs for T2DM. The searching and screening for Source CPGs were guided by tools from the ADAPTE methods with specific inclusion/exclusion criteria. Five reviewers using the second version of the Appraisal of Guidelines for Research and Evaluation (AGREE II) Instrument independently assessed the quality of the retrieved Source CPGs. Domains of Scope and purpose and Clarity of presentation received the highest scores in all CPGs. Most of the assessed CPGs (86%) were considered with high overall quality and were recommended for use. Rigour of development and applicability domains were together highest in 3 CPGs (43%). The overall high quality of DM CPGs published in the last 3 years demonstrated the continuous development and improvement in CPG methodologies and standards. Health care professionals should consider the quality of any CPG for T2DM before deciding to use it in their daily clinical practice. Three CPGs have been identified, using the AGREE criteria, as high-quality and trustworthy. Ideally, the resources provided by the AGREE trust including the AGREE II Instrument should be used by a clinician to scan through the large number of published T2DM CPGs to identify the CPGs with high methodological quality and applicability. © 2017 John Wiley & Sons, Ltd.

    Previous work in cattle illustrated the protective efficacy and negative marker potential of a A serotype foot-and-mouth disease virus (FMDV) vaccine prepared from a virus lacking a significant portion of the VP1 G-H loop (termed A(-)). Since this deletion also includes the arginine-glycine-aspartate (RGD) motif required for virus attachment to the host cell in vivo, it was hypothesised that this virus would be attentuated in naturally susceptible animals. The A(-) virus was passaged three times in cattle via needle inoculation of virus suspension delivered into the intradermal space of the tongue (intradermolingual: IDL). Included in the study were three direct contact cattle, two of which were used for the third cattle passage (by inoculation) after direct contact exposure for three days. Cattle were monitored for clinical signs and samples were collected for sequencing as well as antibody and viral genome detection by ELISA and qRT-PCR. Following needle inoculation with the A(-) virus, naïve cattle developed typical clinical signs of FMDV infection, diagnostic assays also provided positive serological and virological results. However, the contact cattle did not develop clinical signs or generate serological or virological markers indicative of FMDV infection even when the cattle were subsequently needle inoculated with 10(5) TCID50 A(-) FMDV delivered IDL following three days of direct contact exposure. The results suggest that the A(-) virus is not attentuated in cattle when inoculated IDL. This virus could be useful as a tool to understand further the natural pathogenesis, receptor usage and internalisation pathways of FMDV. Crown Copyright © 2013. Published by Elsevier B.V.

    To evaluate the safety, tolerability and immunogenicity of three different doses (5, 25 and 50 µg) of the novel antituberculous vaccine RUTI compared to placebo in subjects with latent tuberculosis infection. Double-blind, randomized, placebo-controlled Phase II Clinical Trial (95 patients randomized). Three different RUTI doses and placebo were tested, randomized both in HIV-positive (n = 47) and HIV-negative subjects (n = 48), after completion of one month isoniazid (INH) pre-vaccination. Each subject received two vaccine administrations, 28 Days apart. Five patients withdrew and 90 patients completed the study. Assessment of safety showed no deaths during study. Two subjects had serious adverse events one had a retinal detachment while taking INH and was not randomized and the other had a severe local injection site abscess on each arm and was hospitalized; causality was assessed as very likely and by the end of the study the outcome had resolved. All the patients except 5 (21%) patients of the placebo group (3 HIV+ and 2 HIV-) reported at least one adverse event (AE) during the study. The most frequently occurring AEs among RUTI recipients were (% in HIV+/-): injection site reactions [erythema (91/92), induration (94/92), local nodules (46/25), local pain (66/75), sterile abscess (6/6), swelling (74/83), ulcer (20/11), headache (17/22) and nasopharyngitis (20/5)]. These events were mostly mild and well tolerated. Overall, a polyantigenic response was observed, which differed by HIV- status. The best polyantigenic response was obtained when administrating 25 µg RUTI, especially in HIV-positive subjects which was not increased after the second inoculation. This Phase II clinical trial demonstrates reasonable tolerability of RUTI. The immunogenicity profile of RUTI vaccine in LTBI subjects, even being variable among groups, allows us considering one single injection of one of the highest doses in future trials, preceded by an extended safety clinical

    Adenocarcinoma originating from the digestive system is a major contributor to cancer-related deaths worldwide. Tumor recurrence, advanced local growth and metastasis are key factors that frequently prevent these tumors from curative surgical treatment. Preclinical research has demonstrated that the dependency of these tumors on supporting mesenchymal stroma results in susceptibility to cell-based therapies targeting this stroma. TREAT-ME1 is a prospective, uncontrolled, single-arm phase I/II study assessing the safety and efficacy of genetically modified autologous mesenchymal stromal cells (MSC) as delivery vehicles for a cell-based gene therapy for advanced, recurrent or metastatic gastrointestinal or hepatopancreatobiliary adenocarcinoma. Autologous bone marrow will be drawn from each eligible patient after consent for bone marrow donation has been obtained (under a separate EC-approved protocol). In the following ~10 weeks the investigational medicinal product (IMP) is developed for each patient. To this end, the patient's MSCs are stably transfected with a gamma-retroviral, replication-incompetent and self-inactivating (SIN) vector system containing a therapeutic promoter - gene construct that allows for tumor-specific expression of the therapeutic gene. After release of the IMP the patients are enrolled after given informed consent for participation in the TREAT-ME 1 trial. In the phase I part of the study, the safety of the IMP is tested in six patients by three treatment cycles consisting of re-transfusion of MSCs at different concentrations followed by administration of the prodrug Ganciclovir. In the phase II part of the study, sixteen patients will be enrolled receiving IMP treatment. A subgroup of patients that qualifies for surgery will be treated preoperatively with the IMP to verify homing of the MSCs to tumors as to be confirmed in the surgical specimen. The TREAT-ME1 clinical study involves a highly innovative therapeutic strategy combining cell

    Full Text Available Abstract Background High grade primary bone sarcomas are rare cancers that affect mostly children and young adults. Osteosarcoma and Ewing sarcoma are the most common histological subtypes in this age group, with current multimodality treatment strategies achieving 55-70% overall survival. As there remains an urgent need to develop new therapeutic interventions, we have reviewed published phase I/II trials that have been reported for osteosarcoma and Ewing sarcoma in the last twenty years. Results We conducted a literature search for clinical trials between 1990 and 2010, either for trials enrolling bone sarcoma patients as part of a general sarcoma indication or trials specifically in osteosarcoma and Ewing sarcoma. We identified 42 clinical trials that fulfilled our search criteria for general sarcoma that enrolled these patient groups, and eight and twenty specific trials for Ewing and osteosarcoma patients, respectively. For the phase I trials which enrolled different tumour types our results were incomplete, because the sarcoma patients were not mentioned in the PubMed abstract. A total of 3,736 sarcoma patients were included in these trials over this period, 1,114 for osteosarcoma and 1,263 for Ewing sarcoma. As a proportion of the worldwide disease burden over this period, these numbers reflect a very small percentage of the potential patient recruitment, approximately 0.6% for Ewing sarcoma and 0.2% for osteosarcoma. However, these data show an increase in recent activity overall and suggest there is still much room for improvement in the current trial development structures. Conclusion Lack of resources and commercial investment will inevitably limit opportunity to develop sufficiently rapid improvements in clinical outcomes. International collaboration exists in many well founded co-operative groups for phase III trials, but progress may be more effective if there were also more investment of molecular and translational research into

The purpose of this paper is to experimentally assess the unique spatial resolution characteristics of this nonlinear reconstruction method and identify its potential impact on the detectabilities and the associated radiation dose levels for specific imaging tasks. Methods: The thoracic section of a pediatric phantom was repeatedly scanned 50 or 100 times using a 64-slice clinical CT scanner at four different dose levels [CTDI{sub vol} =4, 8, 12, 16 (mGy)]. Both filtered backprojection (FBP) and MBIR (Veo{sup ®}, GE Healthcare, Waukesha, WI) were used for image reconstruction and results were compared with one another. Eight test objects in the phantom with contrast levels ranging from 13 to 1710 HU were used to assess spatial resolution. The axial spatial resolution was quantified with the point spread function (PSF), while the z resolution was quantified with the slice sensitivity profile. Both were measured locally on the test objects and in the image domain. The dependence of spatial resolution on contrast and dose levels was studied. The study also features a systematic investigation of the potential trade-off between spatial resolution and locally defined noise and their joint impact on the overall image quality, which was quantified by the image domain-based channelized Hotelling observer (CHO) detectability index d′. Results: (1) The axial spatial resolution of MBIR depends on both radiation dose level and image contrast level, whereas it is supposedly independent of these two factors in FBP. The axial spatial resolution of MBIR always improved with an increasing radiation dose level and/or contrast level. (2) The axial spatial resolution of MBIR became equivalent to that of FBP at some transitional contrast level, above which MBIR demonstrated superior spatial resolution than

    The clinical significance of the measurement of plasma transferrin (Tf) in patients with hypophysial disorders was reported in our previous papers. In the present study, we determined plasma Tf levels in 55 patients with various endocrine states and considered their clinical significance compared with plasma somatomedin-C (SM-C) levels. Plasma Tf levels decreased significantly in patients with anorexia nervosa (p less than 0.02), hyperthyroidism (p less than 0.05), primary hypothyroidism (p less than 0.05) and Cushing's syndrome (p less than 0.05), while they were elevated significantly in pregnancy (p less than 0.01) or females using estrogens (p less than 0.05). The former two declines were considered a reflection of the malnutritional state of the patients since a significant negative correlation was observed between plasma Tf levels and the percentile deficit from the ideal body weight in patients with anorexia nervosa (p less than 0.01), or between plasma Tf levels and elevated T3 levels which induce hypermetabolism in patients with hyperthyroidism (p less than 0.01). A significant correlation was observed between the SM-C and Tf levels in these subjects (including normal controls and patients with hypophysial disorders) as a whole (r = 0.79, p less than 0.001). These data indicate that plasma Tf is changeable according to the endocrinological and nutritional conditions with good correlation to the SM-C, and it is suggested that Tf also operates as a growth factor in vivo.

    The growth of the population of cattle egrets (Bubulcus ibis) in the archipelago of Fernando de Noronha constitutes a threat to public health and biological diversity because of their competition with and predation on native species and the possibility of transmission of pathogens to human beings, livestock and native wildlife. The aim here was to search for, isolate and identify serovars of Salmonella in clinically healthy local cattle egrets. Cloacal swabs were obtained from 456 clinically healthy cattle egrets of both sexes and a variety of ages. The swabs were divided into 51 pools. Six of these (11.7%) presented four serovars of Salmonella enterica subspecies enterica: Salmonella serovar Typhimurium; Salmonella serovar Newport; Salmonella serovar Duisburg; and Salmonella serovar Zega. One sample was identified as S. enterica subspecies enterica O16:y:-. Results in this study suggest that cattle egrets may be reservoirs of this agent on Fernando de Noronha and represent a risk to public health and biological diversity. Copyright © 2018.

    Purpose: Ras/MEK/ERK pathway activation is common in oral cavity squamous cell carcinoma (OCSCC). We performed a neoadjuvant (preoperative) trial to determine the biomarker and tumor response of OCSCC to MEK inhibition with trametinib. Experimental Design: Patients with stage II-IV OCSCC received trametinib (2 mg/day, minimum 7 days) prior to surgery. Primary tumor specimens were obtained before and after trametinib to evaluate immunohistochemical staining for p-ERK1/2 and CD44, the primary endpoint. Secondary endpoints included changes in clinical tumor measurements and metabolic activity [maximum standardized uptake values (SUV max ) by F-18 fluorodeoxyglucose positron emission tomography/CT), and in tumor downstaging. Drug-related adverse events (AE) and surgical/wound complications were evaluated. Results: Of 20 enrolled patients, 17 (85%) completed the study. Three patients withdrew because of either trametinib-related ( n = 2: nausea, duodenal perforation) or unrelated ( n = 1: constipation) AEs. The most common AE was rash (9/20 patients, 45%). Seventeen patients underwent surgery. No unexpected surgical/wound complications occurred. Evaluable matched pre- and posttrametinib specimens were available in 15 (88%) of these patients. Reduction in p-ERK1/2 and CD44 expression occurred in 5 (33%) and 2 (13%) patients, respectively. Clinical tumor response by modified World Health Organization criteria was observed in 11 of 17 (65%) evaluable patients (median 46% decrease, range 14%-74%). Partial metabolic response (≥25% reduction in SUV max ) was observed in 6 of 13 (46%) evaluable patients (median 25% decrease, range 6%-52%). Clinical-to-pathologic tumor downstaging occurred in 9 of 17 (53%) evaluable patients. Conclusions: Trametinib resulted in significant reduction in Ras/MEK/ERK pathway activation and in clinical and metabolic tumor responses in patients with OCSCC.

    Full Text Available The present clinical trial was designed to evaluate the regenerative potential of periodontal tissues in degree II"nfurcation defects at mandibular molars of human using a slow-resorbing collagen membrane and a surgical treatment"ntechnique based on the principles of guided tissue regeneration."nThe patient sampleinclude 8 subjects who had periodontal lessions in right and left mandibular molars regions, including moderate to advance periodonal destruction within the radicular area. Following a baseline examination including recording the clinical measurements (PD, Al, HC, F.G.M , the furcation- involved molars were randomly assigned in each patient to either a test or a control treatment procedure. Included the evevation of mucoperiosteal flaps, recording measurement from the cemento enamel junction (C.E.J directly coronal to the furcation area to the alveolar crest and to the base of the defect-Horizontal furcation measurements were also made using a William's probe, finally a collagen membrrane placed on the involved area to cover the entrance of the furcation and adjucent root surfaces as well as a portion of the alveolar bone apical to the crest. The flaps were repositioned and secured with interdental sutures. A procedure identical to the one used at the test teeth was Performed at the control teeth region with the exception of the placement of the collagen membrance. Following surgery all patients were placed on a plaque control regimen. All Patients received normal postsurgical care and at 6 month post-surgery were scheduled for re-entry surgery. Before re-entry surgery all clinical parameters recorded again. The re-entry mucoperiosteal flaps were designed to expose the furcation area for measurements, as describedabove. There was clinical improvement in all measurements made in both the test and control patients (especially in test group over the 6 month period. The horizontal and vertical furcation measurements did yield a

    Chicken type II collagen (CCII) is a protein extracted from the cartilage of chicken breast and exhibits intriguing possibilities for the treatment of autoimmune diseases by inducing oral tolerance. A 24-week, double-blind, double-dummy, randomized, methotrexate (MTX)-controlled study was conducted to evaluate the efficacy and safety of CCII in the treatment of rheumatoid arthritis (RA). Five hundred three RA patients were included in the study. Patients received either 0.1 mg daily of CCII (n = 326) or 10 mg once a week of MTX (n = 177) for 24 weeks. Each patient was evaluated for pain, morning stiffness, tender joint count, swollen joint count, health assessment questionnaire (HAQ), assessments by investigator and patient, erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP) by using the standard tools at baseline (week 0) and at weeks 12 and 24. Additionally, rheumatoid factor (RF) was evaluated at weeks 0 and 24. Measurement of a battery of biochemical parameters in serum, hematological parameters, and urine analysis was performed to evaluate the safety of CCII. Four hundred fifty-four patients (94.43%) completed the 24-week follow-up. In both groups, there were decreases in pain, morning stiffness, tender joint count, swollen joint count, HAQ, and assessments by investigator and patient, and all differences were statistically significant. In the MTX group, ESR and CRP decreased. RF did not change in either group. At 24 weeks, 41.55% of patients in the CCII group and 57.86% in the MTX group met the American College of Rheumatology 20% improvement criteria (ACR-20) and 16.89% and 30.82%, respectively, met the ACR 50% improvement criteria (ACR-50). Both response rates for ACR-20 and ACR-50 in the CCII group were lower than those of the MTX group, and this difference was statistically significant (P < 0.05). The DAS28 (disease activity score using 28 joint counts) values of the two treatment groups were calculated, and there was a statistically

    The aim was to describe the clinical orthopedic implications of oligofructose overload. A group of 8 nonpregnant dairy heifers were given an oral dose of oligofructose (17 g/kg of body weight). At predefined times during a period spanning 3 d before and 9 d after oligofructose overload, the heifers underwent a clinical examination including locomotion scoring, hoof-testing, and palpation of tarso-crural joints, as well as the collection of blood and ruminal fluid samples. Locomotion sessions were videotaped; subsequently, locomotion was blind-scored. Locomotion scores increased after oligofructose overload and declined toward the end of the study period. The greatest locomotion scores were recorded on d 3 to 5 (60 to 120 h) where 12 of 42 (29%) locomotion scores were 3 and 13 of 42 (32%) were score 2. Positive reactions to hoof-testing were observed from 30 h after oligofructose overload and reached a maximum on d 7 and 9 where 12 of 28 (43%) reactions were marked positive. Distension of the tarso-crural joints was observed from 24 h after oligofructose overload, with maximum distension being observed on d 2, in which 44 of 56 (79%) of observed joints were either moderately or severely distended. The heifers developed classic signs of acute ruminal and systemic acidosis after the oligofructose overload (ruminal pH 4.3 +/- 0.07, standard base excess -10.8 +/- 2.3 at 18 h). With few exceptions, clinical and laboratory variables returned to normal within 9 d of oligofructose overload. But, good body condition and previous feeding with grass apparently predisposed the heifers to more severe systemic affection. Oligofructose overload in dairy heifers induced ruminal and systemic acidosis, diarrhea, dehydration, and, subsequently, lameness, claw pain, and joint effusion, collectively interpreted as signs of acute laminitis. Oligofructose overload at 17 g/kg of body weight represented a relatively mild laminitis model in cattle, as demonstrated by a reasonably quick

    Full Text Available Este estudo retrospectivo incluiu achados clínicos e patológicos de 15 bovinos afetados por raiva. Em treze dos quinze casos, raiva foi confirmada por imunofluorescência direta. Bovinos entre 4 meses e 8 anos foram afetados. O curso clínico variou de três a sete dias. A forma paralítica foi a mais frequente e incluiu incoordenação, paresia e paralisia dos membros pélvicos, decúbito, movimentos de pedalagem e morte. Os principais achados histopatológicos foram meningoencefalite linfoplasmocitária associada com corpúsculos de Negri em 86,6% dos casos. Todos os casos foram positivos na imuno-histoquímica para raiva, cujas reações foram mais evidentes no tronco encefálico, incluindo bulbo, ponte e mesencéfalo, além de gânglio trigêmeo. A imuno-histoquímica demonstrou o vírus da raiva em axônios, dendritos e pericário de neurônios, como agregados de grânulos ou em formações arredondadas associadas com números variáveis de corpúsculos de inclusão virais nos neurônios.
