Intraperitoneal free air (IFA) is sometimes accompanied by pneumatosis cystoides intestinalis (PCI); therefore, proper diagnosis is essential for PCI management. We report two cases of PCI with IFA. A 70-year-old female taking anti-psychotic medication for schizophrenia presented with repeated vomiting and high-grade fever. Computed tomography revealed small, linear gaseous cysts in the intestinal wall along with IFA. Although there was no sign of peritoneal irritation, intestinal perforation was not excluded...

BACKGROUND: Hantaan and Seoul viruses, in the Hantavirus genus, are known to cause hemorrhagic fever with renal syndrome (HFRS). The plaque reduction neutralization test (PRNT), as conventional neutralization test for hantaviruses, is laborious and time-consuming. Alternatives to PRNT for hantaviruses are required. METHODS: In this study, the methods for Hantaan and Seoul viruses serological typing including microneutralization test (MNT), pseudoparticle neutralization test (PPNT) and immunofluorescence assay based on viral glycoproteins (IFA-GP) were developed and compared with PRNT using a panel of 74 sera including 44 convalescent sera of laboratory confirmed HFRS patients and 30 patients sera of non-hantavirus infection...

Psychometric models for item-level data are broadly useful in psychology. A recurring issue for estimating item factor analysis (IFA) models is low-item endorsement (item sparseness), due to limited sample sizes or extreme items such as rare symptoms or behaviors. In this paper, I demonstrate that under conditions characterized by sparseness, currently available estimation methods, including maximum likelihood (ML), are likely to fail to converge or lead to extreme estimates and low empirical power. Bayesian estimation incorporating prior information is a promising alternative to ML estimation for IFA models with item sparseness...

Transferon, a human dialyzable leukocyte extract (hDLE), is a biotherapeutic that comprises a complex mixture of low-molecular-weight peptides (< 10 kDa) and is used to treat diseases with an inflammatory component. Some biotherapeutics, including those composed of peptides, can induce anti-drug antibodies (ADA) that block or diminish their therapeutic effect. Nevertheless, few studies have evaluated peptide-derived drug immunogenicity. In this study, the immunogenicity of Transferon was examined in a murine model during an immunization scheme using the following adjuvants: Al(OH)3, incomplete Freund's adjuvant (IFA), or Titermax Gold...

Improving maternal nutrition practices during pregnancy is essential to save lives and improve health outcomes for both mothers and babies. This paper examines the maternal, household, and health service factors influencing maternal nutrition practices in the context of a large scale maternal, newborn, and child health (MNCH) program in Bangladesh. Data were from a household survey of pregnant (n = 600) and recently delivered women (n = 2,000). Multivariate linear and logistic regression analyses were used to examine the determinants of three outcomes: consumption of iron and folic acid (IFA) tablets, calcium tablets, and diverse diets...

BACKGROUND: Pneumocystis pneumonia (PCP) is a serious risk for HIV-positive patients. Asymptomatic infection or colonisation with P. jirovecii has been shown to occur frequently. PCR assays frequently identify such cases, due to their high sensitivity. Quantitative real-time PCR (qPCR) gene copy number cut-off values have been suggested to differentiate colonisation and infection; these need to be standardised for routine use. We compared the results of qPCR with an immunofluorescence assay (IFA) to determine a specific cut-off value...

BACKGROUND: Serologic diagnosis is one of the most widely used diagnostic methods for Q fever, but the window period in antibody response of 2 to 3 weeks after symptom onset results in significant diagnostic delay. We investigated the diagnostic utility of Q fever PCR from formalin-fixed liver tissues in Q fever patients with acute hepatitis. METHODS: We reviewed the clinical and laboratory data in patients with Q fever hepatitis who underwent liver biopsy during a 17-year period, and whose biopsied tissues were available...

Bovine gammaherpesvirus 4 (BoHV-4) is a herpesvirus widespread in cattle populations, and with no clear disease association. Its genome contains a long unique coding region (LUR) flanked by polyrepetitive DNA and 79 open reading frames (ORFs), with unique 17 ORFs, named Bo1 to Bo17. In 2009, a BoHV-4 strain was isolated (FMV09-1180503: BoHV-4-FMV) from cattle with respiratory disease from Quebec, Canada, and its LUR was sequenced. Despite the overall high similarity, BoHV-4-FMV had the most divergent LUR sequence compared to the two known BoHV-4 reference strain genomes; most of the divergences were in the Bo genes and in the repeat regions...

Neospora caninum causes reproductive problems in cattle such as abortion, premature birth, retention of fetal membranes, and metritis. Therefore, this study aimed to verify possible risk factors for N. caninum infection in dairy cattle and their cause-effect relation to neosporosis. Serum samples of 1518 dairy cows from the West of Santa Catarina State, Southern Brazil were analyzed by indirect immunofluorescence assay (IFA) for N. caninum, where 466 were found to be positives (30.69%-CI95%; 28.3-33.0). In addition, an epidemiological survey was conducted in order to verify possible risk factors for neosporosis and their relation to the disease...

BACKGROUND: The interfrontal angle (IFA) has been utilized as a surrogate for morphologic assessment of the anterior cranial region in metopic synostosis with success in characterizing presenting severity. Its utility as an outcome measure has not been assessed similarly. In this study, we aimed to determine whether meaningful information relative to shape, and relapse in particular, could be assessed using the IFA. METHODS: Patients with operatively treated isolated metopic synostosis were identified and included based on the availability of "previously obtained" low-dose computerized tomography (CT) scans at (1) preoperative and 2 postoperative (2) postoperative day-3 and (3) 1 year time points...

INTRODUCTION: Anaemia continues to be a major hurdle to achieve optimum health in Indian population context. Although government continues to promote Iron Folic Acid (IFA) supplementation as one of the key strategies to combat with burden of anaemia, the expected level of IFA consumption and subsequent anaemia reduction could not be achieved. This study tries to investigate those influences, concerns, experiences and behaviour from an end user perspective through a qualitative methodology which may affect the IFA consumption ambi-directionally...

OBJECTIVES: The genetic basis of PFE (OMIM ID: 125350) was interrogated using molecular functional studies. PFE is a disorder that results in a poor prognosis in the eruption of teeth and by extension, in treatment with a continuous archwire. We tested the hypothesis that PTH1R mutations result in loss of function due to altered protein structure to determine (i) the fate of a functional PTH1R mutation and (ii) the resulting PTH1R protein structure of each functional mutation. METHODS: We used immunofluorescence assay of COS7 cells that were transfected with either the WT or 1092delG PTH1R mutation sequence to compare the fate of the expressed protein...
