Comparative Susceptibility of Brown Trout and Rainbow Trout to Discocotyle sagittata (Monogenea)

The susceptibility of brown trout (Salmo trutta) and rainbow trout (Oncorhynchus mykiss) to the monogenean Discocotyle sagittata in the United Kingdom was assessed by experimental infection of naive fish. One month postinfection with 100 oncomiracidia/host, brown trout harbored significantly lower burdens (27.7 worms/host ± 4.13 SE) than rainbow trout (47.8 worms/host ± 3.90; P = 0.002). This indicates that the consistently lower prevalence and intensity of D. sagittata recorded in naturally infected farmed fishes reflects differences in susceptibility to the parasite. The outcome may be related to the comparatively short-term association of this parasite with rainbow trout (introduced to Britain in the 1880s) compared with the established native host–parasite association.
The role of international competences in increasing graduates’ access to the labor market

Abstract The transition from student to employee status has become an important issue for labor market analysts, students and universities. Literature recognizes that the international experience represents a successful factor for future employability. In this regard, a new curricular model should include international competences in order to build the qualifications required by the global labor market. A recent study (Stan, Butum & Zodieru, 2016) highlighted the importance of youngsters’ professional training upon graduation and the crucial role of collaboration between universities, companies and governments (through education policies) in increasing graduates’ accessibility to well - paid jobs and in developing an entrepreneurial career. The same study provides the results of a qualitative research that leads to the conclusion that most Romanian students have the capacity to obtain the desired job if they can swiftly gain the soft skills required by companies. It is also mentioned that the labor market has increased the demand for international competences and practical skills in recent years. The purpose of this article is to analyze the dynamics of Romanian and European students’ feedback on their universities. Beginning with the analysis of soft skills needed for the labor market and their appreciation as perceived by students, the study will examine the dynamics of students’ appreciation on international experience and other work activities that ensure the achievement of international competences and reduce the time for obtaining a job. Afterward, the paper will analyze students’ career priorities and students’ perception of university performance in providing practical and international skills needed for the labor market. The analysis will include 3-year statistic data from Trendence Graduate Barometer regarding Romanian students’ perception. The conclusions will show the dynamic of students’ expectations on provided skills and the connection with their career priorities. Furthermore, the main results of this study will represent a basis for future research in designing a guide for developing the internationalized curriculum, as well as for a future analysis of the international competences needed by students when searching for a well-paid job.
Novel hepatitis E virus (HEV) isolates from Europe: Evidence for additional genotypes of HEV

Hepatitis E infection is associated with areas in which hepatitis E virus (HEV) infection is endemic. Acute infections in industrialized nations are usually linked to travel to endemic areas. Recently, an acute hepatitis infection in a patient from the United States (US), with no recent foreign travel history, was linked to a novel strain of HEV. Although a few additional cases have been reported from patients who have not traveled to endemic areas, the source of these infections has not been determined. The objective of this study was to identify additional HEV isolates from patients with acute infection who had no recent history of travel to areas where HEV is considered endemic, and to determine the genetic relationship between these and other HEV isolates. Viral RNA was isolated from serum and polymerase chain reaction (PCR) was performed using consensus primers based on a number of HEV isolates. HEV sequence in open reading frame (ORF) 1 and ORF2 was identified in three patients from nonendemic areas, one from Italy and two from Greece. Comparative and phylogenetic analyses were performed. The Greek and Italian isolates were significantly divergent from two isolates from the US and isolates identified previously from HEV‐endemic regions. The Italian isolate was distinct from the two Greek isolates. In addition, the two Greek isolates were significantly divergent from each other. Phylogenetic analysis indicated that the Italian and two Greek isolates represent three new genotypes of HEV, distinct from the Burmese, Mexican, and US genotypes. J. Med.

Antibody-Dependent Cell-Mediated Cytotoxicity in Simian Immunodeficiency Virus-Infected Rhesus Monkeys

ABSTRACT With the recent demonstration in the RV144 Thai trial that a vaccine regimen that does not elicit neutralizing antibodies or cytotoxic T lymphocytes may confer protection against human immunodeficiency virus type 1 (HIV-1) infection, attention has turned to nonneutralizing antibodies as a possible mechanism of vaccine protection. In the current study, we evaluated the kinetics of the antibody-dependent cell-mediated cytotoxicity (ADCC) response during acute and chronic SIVmac251 infection of rhesus monkeys. We first adapted a flow cytometry-based ADCC assay, evaluating the use of different target cells as well as different strategies for quantitation of activated natural killer (NK) cells. We found that the use of SIVmac251 Env gp130-coated target cells facilitates analyses of ADCC activity with a higher degree of sensitivity than the use of simian immunodeficiency virus (SIV)-infected target cells; however, the kinetics of the measured responses were the same using these different target cells. By comparing NK cell expression of CD107a with NK cell expression of other cytokines or chemokine molecules, we found that measuring CD107a expression is sufficient for evaluating the anti-SIV function of NK cells. We also showed that ADCC responses can be detected as early as 3 weeks after SIVmac251 infection and that the magnitude of this antibody response is inversely associated with plasma viral RNA levels in animals with moderate to high levels of viral replication. However, we also demonstrated an association between NK cell-mediated ADCC responses and the amount of SIVmac251 gp140 binding antibody that developed after viral infection. This final observation raises the possibility that the antibodies that mediate ADCC are a subset of the antibodies detected in a binding assay and arise within weeks of infection.
Carpal Tunnel Release by the Agee Endoscopic Technique

Ninety-five hands (86 patients) were treated by endoscopic carpal tunnel release using the technique of Agee. They were the first ones operated on by the senior author (GF) using this technique. The patients were interviewed at a mean follow-up of 4.5 years: 72% of hands were free of symptoms and 94% were described by the patients as functionally normal. Seventeen hands (out of 27) with residual or recurrent symptoms were examined. Nine hands (nine patients) were only partially improved (mean 6.7 on a 10 point scale) and in eight hands (seven patients), some symptoms had recurred after a mean delay of 3.8 years. It was possible to find a second pathology in most of these cases. It is necessary to inform the patient before operation that incomplete relief or recurrence of symptoms can occur after endoscopic carpal tunnel release, as with conventional release.
The Association between Brand Equity and Customer Store Selection in Zimbabwean Fast Foods Industry

This paper delves into the impact of brand equity on customer store selection in the fast foods industry of Bindura in Zimbabwe. The association between brand equity elements (awareness, loyalty, image and associations) and customer store selection was tested. The research adopted both qualitative and quantitative research paradigms. Sample of 100 respondents was selected using convenience sampling method. The results showed that brand awareness has indirect relationship with customers’ store selection while loyalty, image and association have a strong positive correlation with customer store selection. By implication, all brand equity elements require a wise attention.
Epidemiology and Clinical Significance of Blood Cultures Positive for Coagulase-Negative Staphylococcus

Abstract Coagulase-negative staphylococci are frequently isolated from blood cultures. As these organisms may occasionally cause serious disease, differentiating bacteremia from contamination is very important but often difficult. Over a 26-month period, of 29,542 blood cultures processed at the University of Michigan Medical Center, 2,875 (9.7%) were positive, and of those, 694 (from 527 patients) grew coagulase-negative staphylococci. Isolates from the 439 patients with only one blood culture positive for coagulase-negative staphy-lococci and those from the 18 patients with two positive cultures 10 days or more apart were deemed contaminants. Review of the records of the remaining 70 patients with multiple isolates indicated that 33 had had an episode of true bacteremia, 29 (87.9%) of which were associated with intravascular catheters or prosthetic valves. Overall, 85% of all coagulase-negative staphylococci isolated during the study period were judged to be contaminants. Seventy-one percent of the blood cultures drawn during the episodes of bacteremia were positive for coagulase-negative staphylococci as opposed to only 34% in the patients with contaminated cultures (p < 0.01). Moreover, coagulase-negative staphylococci grew in both aerobic and anaerobic bottles in 85% of blood culture sets drawn during episodes of bacteremia, but in only 30% of the cultures thought to be contaminated (p < 0.001). Growth of coagulase-negative staphylococci in less than 48 hours was also significantly associated with bacteremia (p < 0.01). Antibiotic sensitivity patterns were not useful in differentiating bacteremia from contamination. Thus, clinicians should consider coagulase-negative staphylococci as true blood pathogens in patients with intravascular devices who have a high proportion of blood cultures positive for this organism over a short period of time, and whose cultures became positive in less than 48 hours, with a high percent positive in both bottles. Microbiology laboratories can conserve considerable resources by limiting sensitivity studies to isolates from such patients.
A high‐throughput screen for ligand binding reveals the specificities of three amino acid chemoreceptors from Pseudomonas syringae pv. actinidiae

Chemoreceptors play a central role in chemotaxis, allowing bacteria to detect chemical gradients and bias their swimming behavior in order to navigate toward favorable environments. The genome of the kiwifruit pathogen, Pseudomonas syringae pv. actinidiae (Psa) strain NZ‐V13 encodes 43 predicted chemoreceptors, none of which has been characterized. We developed a high‐throughput fluorescence‐based thermal shift assay for identifying the signal molecules that are recognized by a given chemoreceptor ligand binding domain (LBD). Using this assay, we characterized the ligand binding profiles of three Psa homologs of the P. aeruginosa PAO1 amino acid chemoreceptors PctA, PctB and PctC. Each recombinant LBD was screened against 95 potential ligands. The three Psa homologs, named pscA, pscB and pscC (Psa chemoreceptors A, B and C) bound 3, 10 and 3 amino acids respectively. In each case, their binding profiles were distinct from their P. aeruginosa PAO1 homologs. Notably, Psa PscA‐LBD only bound the acidic amino acids l‐aspartate, d‐aspartate and l‐glutamate, whereas P. aeruginosa PctA‐LBD binds all of the l‐proteinogenic amino acids except for l‐aspartate and l‐glutamate. A combination of homology modeling, site‐directed mutagenesis and functional screening identified a single amino acid residue in the Psa PscA‐LBD (Ala146) that is critically important for determining its narrow specificity.
When More Yields Less: Speaking and Writing Deficits in Nonfluent Progressive Aphasia

Fourteen patients with nonfluent progressive aphasia (NFPA) performed a picture description task in both spoken- and written-output conditions, as well as tests of confrontation naming, spelling to dictation and reading aloud of single words and text. Relative to controls, the patients’ spoken and written picture descriptions were reduced in length, speed and amount of information. Of particular interest, and accounting for the first part of the article’s title, was a pervasive pattern of poorer spoken and written output associated with the requirement to produce more; this was true when ‘more’ meant either (a) longer vs. shorter single words or (b) connected language vs. single words. Deficits in spoken and written naming were largely parallel, and modality-specific output impairments (such as dysarthria in speech or letter-formation problems in writing) seemed to account for the minority of cases who exhibited a discrepancy. Most patients showed no evidence of agrammatism or of reduced verb production in their speech, which typically had normal proportions of content and function words as well as nouns and verbs. By contrast, some degree of telegraphic output was observed in the written narratives of a number of the patients. Our results argue against several candidates for the main functional locus of impairment in NFPA, but it is likely that deficits in grammatical processing, working memory, planning/executive skills, speech motor abilities and phonological processing all play a role.
Human Epididymis Protein 4: A Novel Biomarker for Lupus Nephritis and Chronic Kidney Disease in Systemic Lupus Erythematosus

Human epididymis protein 4 (HE4) is an available tumor biomarker for detecting ovarian cancer. However, it is unknown if serum HE4 could be a novel biomarker for diagnosis of lupus nephritis (LN) and chronic kidney disease (CKD) in patients with systemic lupus erythematosus (SLE).
Computationally efficient predictive control of three-level NPC converters with DC-link voltage balancing: A priori state selection approach

We propose a novel framework for multistep predictive current control for induction machines. The main contribution of this work is the achievement of the control goal over a long prediction horizon while reaching DC-link balancing for the accompanying three-level neutral point clamped (3L-NPC) inverters at the same time. The multistep prediction horizon is implemented using a sphere decoding algorithm. The DC-link balancing is guaranteed by modifying the sphere decoder such that only neutral point affecting states are selected if the DC-link voltage is imbalanced. Since those states are not uniquely defined for the 3L-NPC inverter, the state that minimizes the DC-link voltage is then selected within a preprocessing stage. The framework is verified by means of simulations.
Immunohistochemical Characterization of Macrophages and Myofibroblasts in α-Naphthylisothiocyanate (ANIT)–Induced Bile Duct Injury and Subsequent Fibrogenesis in Rats

To investigate pathogenesis of post–bile duct (BD) injury fibrosis, interlobular BD epithelial injury was induced in male F344 rats by a single IP injection of α-naphthylisothiocyanate (75 mg/kg body weight) and rats were observed for 12 days. On days 1 to 2, cholangiocytes were injured and desquamated. On days 3 to 5, the affected BD began to regenerate, showing positive staining for CK19 and vimentin. On days 5 to 9, fibrotic areas gradually developed around regenerating BD in Glisson’s sheath. These consisted of cells positive for vimentin, desmin, and α-SMA; vimentin- and desmin-positive cells were increased in early stage (days 1–3), whereas α-SMA-positive cells appeared in mid (days 4–7) and late stages (days 8–12), although there were cells coexpressing these cytoskeletons. On day 12, BD regeneration almost completed, with reduced fibrosis. Macrophages positive for ED2 (CD163) increased transiently in early stage, whereas those reacting to ED1 (CD68), OX6 (MHC II), and SRA-E5 (CD204) showed a consistent increase throughout the experiment. Interestingly, OX6-positive cells were limited to Glisson’s sheath, whereas SRA-E5-positive cells were seen exclusively along sinusoids of hepatic lobules. MCP-1 mRNA increased significantly in early stage. This study shows that macrophages exhibiting different immunophenotypes and distributions participate in post-BD injury fibrosis associated with myofibroblasts expressing various mesenchymal cytoskeletons.
Knowledge of and practices related to smoking cessation among physicians in Nigeria.

OBJECTIVE To evaluate the knowledge and practices of smoking cessation among physicians in Nigeria. METHODS We conducted a cross-sectional survey in Lagos and three geopolitical zones of Nigeria. A self-administered structured questionnaire was used to obtain information on tobacco use and its health effects, as well as on the knowledge and practices of smoking cessation, from 436 physicians. RESULTS Of the 436 physicians, 292 (67.0%) were aware of smoking cessation, but only 132 (30.3%) showed good knowledge on this topic. The prevalence of smoking among the physicians was 17.7%. In addition, 308 physicians (70.6%) reported that tobacco education in the medical school curriculum was inadequate. Of the 436 physicians, 372 (86.2%) asked their patients whether they smoked, and 172 (39.4%) asked their patients the reasons for using tobacco. As a means of smoking cessation intervention, 268 (61.5%) used brief advice/counseling (2-5 min), 12 (3.7%) prescribed antidepressants, 16 (2.8%) prescribed nicotine replacement therapy (NRT), and 76 (17.4%) arranged follow-up visits. When the physicians were questioned regarding the obstacles to smoking cessation interventions, 289 (66.3%) cited poor knowledge of the issue, 55 (12.6%) cited a lack of time, and 20 (4.6%) cited unavailability of NRT. CONCLUSIONS The results of this study highlight the lack of knowledge among physicians in Nigeria in terms of smoking cessation, as well as their failure to apply appropriate practices. The results of this study can further the evaluation and formulation of guidelines on smoking cessation and smoking education programs for physicians. Our findings also underscore the need to offer smoking cessation programs in all treatment facilities.
Thoracic Pediatric Intramedullary Schwannoma: Report of a Case

Schwann cells are generally present in the nerve root, not in the spinal cord. Therefore, intramedullary schwannomas are rare and correct preoperative diagnosis is often difficult. To date, less than 50 cases of intramedullary schwannoma with no sign of neurofibromatosis have been reported in the English literature, of which 5 occurred in children. Here, we report a case of primary thoracic intramedullary schwannoma which occurred at the age of 11, confirmed by intraoperative frozen biopsy. The patient presented with decreased sensation below the T6 dermatome at the right side and right lower extremity weakness with urge incontinence. The ideal treatment for intramedullary schwannoma of histologically benign nature is surgical resection. However, the mass was subtotally resected due to unfavorable intraoperative somatosensory-evoked potential findings, and postoperative fractionated radiotherapy followed. She has been alive with the residual intramedullary mass with no discernible changes during the 11.5 years of follow-up. When neurosurgeons, pediatricians and radiologists encounter an intramedullary tumor in a pediatric patient, intramedullary schwannoma should be included in the differential diagnoses because it might be curable if excised.
Case Control Series of Intrathecal Autologous Bone Marrow Mesenchymal Stem Cell Therapy for Chronic Spinal Cord Injury

Background: Autologous bone marrow mesenchymal cells that include stem cells (MSCs) are a clinically attractive cellular therapy option to try to treat severe spinal cord injury (SCI). Objective: To study the possible value of MSCs injected intrathecally to enhance rehabilitation. Methods: This case control, convenience sample included 64 patients, at a mean of 3.6 years after SCI. Forty-four subjects received monthly intrathecal autologous MSCs for 6 months and 20 subjects, who would not agree to the procedures, served as controls. All subjects received rehabilitation therapies 3 times weekly. Subjects were evaluated at entry and at 12 months after completing the 6-months intervention. By the ASIA Impairment Scale, ASIA grading of completeness of injury, Ashworth Spasticity Scale, Functional Ambulation Classification, and bladder and bowel control questionnaire. Results: No differences were found in baseline measures and descriptors between the MSC group and control group. Although a higher percentage of the MSC group increased motor scores by 1-2 points and changed from ASIA A to B, no significant between-group improvements were found in clinical measures. Adverse effects of cells included spasticity and, in 24 out of the 43 patients developed neuropathic pain. One subject with a history of post-infectious myelitis developed encephalomyelitis after her third injection. Conclusion: Autologus MSCs may have side effects and may be contraindicated in patients with a history of myelitis. Their utility in treating chronic traumatic SCI needs further study in pre-clinical models and in randomized controlled trials before they should be offered to patients.
A Theory‐based Intervention to Improve Nurses' Knowledge, Self‐efficacy, and Skills to Reduce PICC Occlusion

The peripherally inserted central catheter (PICC) is an effective intermediate and long-term central vascular access device. Its functions are comparable with those of other percutaneously placed central venous catheters. However, its high occlusion rate and the consequent infection risk may disrupt therapy for patients. The primary investigator in this study developed an educational intervention based on Albert Bandura's social learning theory, and hypothesized that increasing nurses' knowledge and self-efficacy related to PICCs would have a positive impact on patient outcomes related to occlusion and infection rates. The study outcome showed an overall increase in nurses' knowledge and self-efficacy related to PICC care, and a significant reduction in the catheter occlusion rate, from 29% to 8.5%, over a 6-month period.
