Molecular survey of enteric viruses in commercial chicken farms in Korea with a history of enteritis

Abstract Several enteric viruses have increasingly received attention as potential causative agents of runting-stunting syndrome (RSS) in chickens. A molecular survey was performed to determine the presence of a broad range of enteric viruses, namely chicken astrovirus (CAstV), avian nephritis virus (ANV), chicken parvovirus (ChPV), infectious bronchitis virus (IBV), avian rotavirus (AvRV), avian reovirus (ARV), and fowl adenovirus (FAdV), in intestinal samples derived from 34 commercial chicken flocks that experienced enteritis outbreaks between 2010 and 2012. Using techniques such as PCR and reverse-transcription PCR, enteric viruses were identified in a total of 85.3% of investigated commercial chicken flocks in Korea. Furthermore, diverse combinations of 2 or more enteric viruses were simultaneously identified in 51.7% of chicken farms positive for enteric viruses. The rank order of positivity for enteric viruses was as follows: ANV (44.1%), CAstV (38.2%), ChPV (26.5%), IBV (20.6%), ARV (8.8%), AvRV (5.9%), and FAdV (2.9%). Additionally, other pathogens such as Escherichia coli, Salmonella spp. , Eimeria spp. , and FAdV were detected in 79% of chicken flocks positive for enteric viruses using PCR, bacterial isolation, and microscopic examination. The results of our study indicate the presence of several enteric viruses with various combinations in commercial chicken farms that experienced enteritis outbreaks. Experimental studies are required to further understand the roles of enteric viruses in RSS in commercial chickens.
Energy associated with a Kerr-Newman black hole.

Using Tolman's as well as Landau and Lifshitz's definitions, the energy associated with a Kerr-Newman black hole is calculated. Both definitions give exactly the same result and the total energy is found to be shared by its interior as well as exterior. Switching off the charge parameter (i.e., {ital Q}=0) one finds that no energy is shared by the exterior of the Kerr black hole. Thus the gravitational field seems to have a remarkable difference from the electromagnetic field as the energy in the latter case is shared by the interior as well as exterior of the system producing the electromagnetic field.
Aging, exceptional longevity and comparisons of the Hannum and Horvath epigenetic clocks.

AIM To examine the relationships between two epigenetic clocks, aging and exceptional longevity. MATERIALS & METHODS Participants were from three adult cohorts with blood DNA methylation data (Illumina 450 K, n = 275, 34-103 years). Epigenetic age (DNAmage) and age acceleration measures were calculated using the Hannum and Horvath epigenetic clocks. RESULTS Across all cohorts, DNAmage was correlated with chronological age. In the long-lived cohort (Sydney Centenarian Study; 95+, n = 23), DNAmage was lower than chronological age for both clocks. Mean Sydney Centenarian Study Hannum age acceleration was negative, while the converse was observed for the Horvath model. CONCLUSION Long-lived individuals have a young epigenetic age compared with their chronological age.
Prospective risk of intrauterine death of monochorionic twins: update

Abstract Objective: To calculate an updated prospective risk of fetal death in monochorionic-biamniotic (MCBA) twins. Study design: We evaluated 520 MCBA twin pregnancies that had intensive prenatal surveillance and delivered in a single Portuguese referral center. The prospective risk of fetal death was calculated as the total number of deaths at the beginning of the gestational period divided by the number of continuing pregnancies at or beyond that period. Data were compared to the 2006 previous report. Results: Nearly 80% of the neonates weighed <2500 g, including 13.5% who weighed <1500 g. Half were born at <36 weeks, including 13.8% who were born at <32 weeks. The data indicate an increased IUFD rate over time – 16 fetal deaths per pregnancy (3.1%) and 22 IUFDs per fetus (2.1%). The rate of IUFD after 32–33 weeks, however, was halved (1/187 pregnancies and 1/365 fetuses, 0.5 and 0.3%, respectively). Conclusion: Intensive prenatal surveillance might decrease the unexpected fetal death rates after 33 week’s gestation and our data do not support elective preterm birth for uncomplicated MCBA twins.
Avian Poxvirus Infection in Flamingos (Phoenicopterus roseus) in a Zoo in Japan

Abstract Two diseased flamingos (Phoenicopterus roseus) with nodular lesions (pock) characteristic of poxvirus infection were found in a zoo in Japan. Avian poxvirus was isolated from the lesions (upper beak) of the affected birds and was genetically characterized by polymerase chain reaction, nucleotide sequencing, and phylogenetic analysis. Based on the phylogenetic analysis, the virus isolated from these flamingos was genetically close to those isolated from pigeons, suggesting the possibility of interspecies transmission.
Clinical Experience with Polyurethane‐Covered Gel‐Filled Mammary Prostheses

We have used 104 low-profile polyurethane-covered gel-filled mammary prostheses in 54 patients. Only one patient has developed capsular contracture. Foreign-body reaction to polyurethane was clinically significant in only one patient. Other complications have been few and of the type that can accompany any type of mammary prosthesis. Of the 54 patients studied, 51 still have their implants in place and have soft, compressible breasts. The superior wrinkling and palpable implant edge that is occasionally present when the implant is placed subcutaneously has been of some concern to patients and can be eliminated by submuscular placement. The use of polyurethane-covered low-profile gel-filled prostheses for breast reconstruction has greatly improved our results, and the satisfaction of both surgeon and patient has been gratifying.
Electrostatic nanopatterning of PMMA by AFM charge writing for directed nano-assembly

Electrostatic nanopatterning of poly(methylmethacrylate) (PMMA) thin films by atomic force microscopy (AFM) charge writing was investigated using Kelvin force microscopy (KFM). The lateral size of the electrostatic patterns and the amount of injected charges are closely correlated and can be controlled by the height of the voltage pulses applied to the AFM tip and the tip–sample separation during the writing process. Charge retention measurements show that PMMA has excellent charge storage properties in air under relative humidities from 1% to 60% and withstands immersion in ultra-pure water. This study thus reveals that PMMA is a very promising electret to create efficient electrostatic nanopatterns for directed self-assembly of nanoscale objects, including the broad range of colloidal particles or molecules in aqueous solutions.
Progression of astrocytomas and meningiomas: an evaluation in vitro

Abstract. Objectives/Background: In biological terms, progression means that malignancy increases as genetic mutations accumulate leading to increased proliferation and invasion capacity. By verifying the proliferation capacity, human telomerase reverse transcriptase (hTERT) expression and in vitro invasion, in a group of highly malignant glioblastomas, benign meningiomas and astrocytomas, at the initial stage of progression, we have analysed putative progression in vitro for proliferation and telomerase expression. Materials and Methods: The relative proliferation status (visualized with Ki‐67 antibodies) and presence of hTERT protein was analysed in 27 intracranial tumours (6 astrocytomas, 8 glioblastomas and 13 meningiomas) by immunohistochemistry on paraffin‐embedded biopsy tissue, as well as on primary tumour‐derived cell cultures. A confrontation model was used to analyse invasiveness in vitro. Results: The mean proliferation indices were 22.3 (SD = 18.1) for glioblastomas and 2.1 (SD = 1.9) for low‐grade (LG) astrocytomas. The group of benign meningiomas had a labelling index of 2.2 (SD = 2.7). Mean percentages of staining for hTERT varied between 36.5 (SD = 28.4) for glioblastomas and 10.2 (SD = 8.6) for LG astrocytomas. The group of benign meningiomas had a labelling index of 12.4 (SD = 19.2) for hTERT. A significant difference was seen for Ki‐67 (P < 0.05) and hTERT (P < 0.001) in vivo versus in vitro. No difference was seen between the group of invasive and non‐invasive tumour‐derived cell cultures for the histopathological markers Ki‐67 and hTERT (P > 0.05) in vitro. Conclusions: The elevated expression of hTERT and Ki‐67 in vitro provides a potential prognostic tool for early detection of the progression of brain tumours. As tumour cells require telomerase for continued proliferation, the expression of hTERT may mark immortality, leading to indefinite life span. On the other hand, hTERT expression and cell proliferation are not linked directly to invasion in vitro.
CAN NECK CIRCUMFERENCE PREDICT METABOLIC SYNDROME? AN EXPERIENCE FROM A UNIVERSITY COMMUNITY.

OBJECTIVE Neck circumference (NC) is associated with cardiovascular risk factors. The data for the measurement of the NC to predict metabolic syndrome (MetS) are limited. The objectives of this study were to determine the capability of the NC to detect MetS and to identify the optimal cutoff points of the NC among Thais. METHODS Participants who were aged ≥50 years who attended the Healthy Ageing Khon Kaen University Campus Project between March 2012 and April 2015 were recruited to this cohort study specific for atherosclerotic-related diseases. Baseline characteristics, anthropometric measures including NC, and metabolic profiles were collected. MetS was identified using the criteria of the National Cholesterol Educational Program Adult Treatment Panel III (NCEP ATP III) and International Diabetes Foundation (IDF). RESULTS There were 201 males and 386 females recruited for this study. The areas under the receiver operating characteristic (ROC) curves (AUCs) of NC based on the IDF criteria for females and males were 0.79 (95% confidence interval [CI] 0.75, 0.84) and 0.84 (95% CI 0.79, 0.9), respectively. For the NCEP ATP III criteria, the AUCs were 0.77 (95% CI 0.72, 0.82) in females and 0.71 (95% CI 0.64, 0.78) in males. An NC of 39 cm using IDF criteria for makes was determined as the optimal cutoff point to identify subjects with MetS. An NC of 33 cm for females was the best cutoff point for determining which subjects had MetS using both criteria. CONCLUSION NC measurement and the use of established cutoff points is useful for predicting MetS in older Thai people.
Regulatory Defects in Cbl and Mitogen-Activated Protein Kinase (Extracellular Signal-Related Kinase) Pathways Cause Persistent Hyperexpression of CD40 Ligand in Human Lupus T Cells1

To identify intrinsic defects in lupus, we studied short-term, CD4+ T cell lines that were established from 16 lupus patients (active or inactive) and 15 normal subjects by stimulating once with anti-CD3, anti-CD28, and IL-2. After resting, the pure CD4+ T cells were exposed to anergy-inducing stimulation with plate-bound anti-CD3 mAb in the absence of APC. Lupus T cells showed prolonged high level expression of CD40 ligand (CD40L, CD154) even in the face of anergy protocol, which shut down CD40L expression in normal T cells. The sustained CD40L expression in lupus T cells did not correlate with memory status or Th deviation, and was relatively independent of IL-2 or other autocrine or paracrine signals via CD28 or CTLA-4. Cyclosporin A could block CD40L expression by lupus T cells when added early during the anti-CD3 stimulation period, but only partially when added later, indicating that another mechanism regulates the prolonged hyperexpression of CD40L besides the Ca2+ ⇒ calcineurin-dependent NF-AT pathway. When exposed to the anergy protocol, lupus T cells, in marked contrast to normal T cells, did not phosphorylate Cbl/Cbl-b but continued to express strongly phosphorylated extracellular signal-regulated kinase (ERK); U0126, a specific inhibitor of mitogen-activated protein kinase kinase ⇒ ERK, could block both the early and the prolonged hyperexpression of CD40L. Thus, pathways regulating the activities of Cbl and one particular mitogen-activated protein kinase, ERK, are involved in the prolonged hyperexpression of CD40L in lupus T cells.
The Thai Anesthesia Incidents Study (THAI Study) of anesthetic outcomes: II. Anesthetic profiles and adverse events.

BACKGROUND AND RATIONALE The purposes of the Thai Anesthesia Incidents Study (THAI Study) of anesthetic outcomes were to survey patients, surgical, anesthetic profiles and determine factors related to adverse events. MATERIAL AND METHOD A prospective descriptive study of occurrence screening was conducted in 20 hospitals comprised of 7 university, 4 general and 4 district hospitals across Thailand. Anesthesia personnel were required to fill up patient-related, surgical-related, anesthesia-related variables and adverse outcomes on a structured data entry form. The data were collected during the preanesthetic evaluation, intraoperative period and 24 hr postoperative period. Adverse events specific forms were used to record when they occurred. All data were keyed at data management unit with double entry technique and descriptive statistics was used in the first phase of this study. RESULTS A total of 163403 consecutive cases were recorded during first 12 months. MD. anesthesiologists involved with 82%, 89%, 45% and 0.2% of cases in university hospitals, regional hospitals, general hospitals and district hospitals respectively. Nurse anesthetists took a major involvement in hospitals run by the Ministry of Public Health. Two-thirds of cases did not receive any premedication (67%) and midazolam was most frequent premedication administered (20%). Common monitoring were non invasive blood pressure (NIBP) (97%), pulse oximetry (96%), electrocardiography (80%), urine output (33%), airway pressure (27%) and capnometry (19%) respectively. The choices of anesthesia were general anesthesia (62%), spinal anesthesia (23%), total intravenous anesthesia (6%), monitor anesthesia care (4%), brachial plexus block (3%) and epidural anesthesia (1%). The adverse events were oxygen desaturation (31.9:10000), cardiac arrest (30.8:10000), death within 24 hr. (28.3:10000), difficult intubation (22.5:10000),re-intubation (19.4:10000), unplanned ICU admission (7.2:10000), coma/cva/convulsion (4.8:10000), equipment malfunction/failure (3.4:10000), suspected myocardial ischemia or infarction (2.7:10000), awareness during anesthesia (3.8:10000), late detected esophageal intubation (4.1:10000), failed intubation (3.1:10000), anaphylaxis or anaphylactoid reaction (2.1:10000), nerve injury (2:10000), pulmonary aspiration (2.7:10000), drug error (1.3:10000), hazard to anesthesia personnel (1.5:10000), unplanned hospital admission (0.1:10000), total spinal block (1.3:10000) and mismatch blood transfusion (0.18:10000) CONCLUSION Respiratory adverse events were common anesthesia direct related events. High incidence of cardiac arrest and death within 24 hr highlighted concerns for prevention strategies. Incidents of adverse events can be used for institutional quality improvement, educational quality assurance and further research for patient safety in anesthesia.
Sequence of gp41env immunodominant region of HIV type 1 group O from west central Africa.

HIV-1 group O is endemic in the west central region of Africa, where the frequency of infection is estimated to be 3-10% of all HIV-1-infected individuals. However, international travel and immigration have led to group O cases being identified in France, Germany, Belgium, Spain, and the US. With the exception of an infected French woman, all reported group O-infected individuals originate from or have a connection to west central Africa. Since most immunoassay reagents are based upon HIV-1 group M, many HIV immunoassays have lower sensitivity for the detection of group O infections. Serum samples were collected from patients at hospitals, tuberculosis (TB) clinics, and STD clinics in endemic regions of Cameroon and Equatorial Guinea in a study of the sequence divergence with group O isolate infections. Screening of the 1086 samples using a range of research and commercial immunoassays found 255 to be HIV-1 seropositive. On the basis of differential reactivity in the various immunoassays, 8 individuals were identified as potentially being infected with group O virus, of which 4 were drawn from TB patients. 7 of the group-O samples were then subjected to polymerase chain reaction (PCR) amplification to verify group O infection. The gp41(env) immunodominant region was successfully amplified and sequenced from 4 of the 7 samples, 2 of which were from the TB patients; 4 of 1086 samples were definitely infected with HIV-1 group O.
Informants are not all equal: predictors and correlates of clinician judgments about caregiver and youth credibility.

OBJECTIVE The objectives of this study were to examine how often clinicians judged youths or caregivers to not be credible informants, to identify the associated features of youth or caregiver credibility, and to examine credibility's impact on the validity of mood and behavior checklists. BACKGROUND Clinicians often have the experience of talking to a parent or a youth and judging that the credibility of the information offered is unusually poor. Little is known about the correlates of poor credibility or about the extent to which credibility changes the validity of commonly used checklists. METHODS Interviewers rated the credibility of 646 youths aged 5-18 and their primary caregivers after completing a Kiddie Schedule for Affective Disorders and Schizophrenia. Ratings and diagnoses were blind to the behavior checklists completed by caregivers, youths, and teachers. A subset of youths also had intelligent quotient tests and behavioral observations available. RESULTS Caregivers were perceived as more credible on average than youths, though this dropped sharply with adolescents. Caregiver credibility was higher for better functioning families, more credible youths, younger youths, and more educated caregivers; it was unrelated to caregiver mood symptoms or being the mother. Youth credibility was strongly connected to age, cognitive ability, caregiver credibility, and independent observations of youth behavior. Credibility ratings markedly altered the validity of checklists compared with interview ratings, diagnoses, or cross-informant criteria. CONCLUSION Clinicians' judgments about informant credibility are associated with different characteristics for youths versus caregivers, though youth age is important to both. Credibility affects the validity of information from checklists measured against several different independent criteria.
Phase III study of craniospinal radiation therapy followed by adjuvant chemotherapy for newly diagnosed average-risk medulloblastoma.

PURPOSE To determine the event-free survival (EFS) and overall survival of children with average-risk medulloblastoma and treated with reduced-dose craniospinal radiotherapy (CSRT) and one of two postradiotherapy chemotherapies. METHODS Four hundred twenty-one patients between 3 years and 21 years of age with nondisseminated medulloblastoma (MB) were prospectively randomly assigned to treatment with 23.4 Gy of CSRT, 55.8 Gy of posterior fossa RT, plus one of two adjuvant chemotherapy regimens: lomustine (CCNU), cisplatin, and vincristine; or cyclophosphamide, cisplatin, and vincristine. Results Forty-two of 421 patients enrolled were excluded from analysis. Sixty-six of the remaining 379 patients had incompletely assessable postoperative studies. Five-year EFS and survival for the cohort of 379 patients was 81% +/- 2.1% and 86% +/- 9%, respectively (median follow-up over 5 years). EFS was unaffected by sex, race, age, treatment regimen, brainstem involvement, or excessive anaplasia. EFS was detrimentally affected by neuroradiographic unassessability. Patients with areas of frank dissemination had a 5-year EFS of 36% +/- 15%. Sixty-seven percent of progressions had some component of dissemination. There were seven second malignancies. Infections occurred more frequently on the cyclophosphamide arm and electrolyte abnormalities were more common on the CCNU regimen. CONCLUSION This study discloses an encouraging EFS rate for children with nondisseminated MB treated with reduced-dose craniospinal radiation and chemotherapy. Additional, careful, step-wise reductions in CSRT in adequately staged patients may be possible.
Clinical Trial: Transcutaneous Interferential Electrical Stimulation in Individuals with Irritable Bowel Syndrome – A Prospective Double-Blind Randomized Study

Background: The exact etiology of irritable bowel syndrome (IBS) remains unclear. Curative treatment is not available and current treatment modalities are mainly directed against the predominant symptoms. There are a few studies reporting the beneficial effects of transcutaneous electrical stimulation in patients with chronic constipation, gastroparesis, and functional dyspepsia. Aim: To investigate whether transcutaneous electrical stimulation is an effective procedure in IBS patients. Methods: IBS patients were randomly placed in vacuum interferential current (IFC) and placebo groups. Both treatments consisted of 12 sessions administered over 4 weeks. Symptoms due to IBS were documented via questionnaires, including the IBS Global Assessment of Improvement Scale, numeric rating scales, visual analogue scale, and IBS Quality of Life Scale at the beginning of, end of, and 1 month after the treatment. Results: Patients in the therapy (29 cases) and placebo (29 cases) groups were homogeneous with respect to demographic data and gastrointestinal system symptoms. When compared to the beginning scores, severity of abdominal discomfort, bloating, and abdominal distension and rumbling improved significantly in either interference or placebo groups at both the end of treatment and 1 month after treatment. In the IFC group, severity of symptoms continued to decrease significantly at 1 month after treatment when compared to scores at just the end of treatment, whereas in the placebo group severity of these symptoms did not change significantly on numeric severity scales. Also, the visual analogue scale of the first month after treatment continued to decrease significantly when compared to the level at the end of treatment in the IFC group. Total quality score increased significantly in the IFC group. Conclusions: Vacuum IFC therapy can significantly improve symptoms and quality of life in patients with IBS. It may represent a novel treatment modality for drug-refractory IBS patients.
Pseudoseizures Caused by Hyperventilation Resembling Absence Epilepsy

During the 4-year period, 1982-1986, 18 patients presented to the Children's Hospital, Camperdown, Sydney, with the following features: (1) Recurrent "absences" clinically indistinguishable from childhood absence epilepsy, (2) Normal clinical examination, (3) Electroencephalogram (EEG) demonstrating normal waking background and sleep activity. On hyperventilation, "absences" occurred, characterized on EEG by a marked build-up of paroxysmal slow-wave activity unassociated with evidence of epileptic activity. We designate these attacks "pseudoseizures caused by hyperventilation resembling absence epilepsy. " Individual cases demonstrated a variety of other symptoms consistent with the hyperventilation syndrome. There was an identifiable environmental stress in 13 of the 18 cases. Follow-up of 13 patients after a mean period of 20 months revealed that only two children continued to have occasional absences, associated with a clear history of breathing up when upset. Treatment did not influence outcome. On repeat hyperventilation with EEG and respiratory monitoring, five of the 13 had pseudoseizures. There was no indication that susceptibility to these episodes was associated with an abnormal CO 2 response. It is postulated that the occurrence of pseudoseizures is related to cerebrovascular immaturity and an excessive vasoconstrictor response to a given level of CO2. (J Child Neurol 1990;5:288-294).
