Background Autoimmune atrophic gastritis (AAG) diagnosis is based on specific histological findings and anti-parietal cell antibodies (PCA) considered the serological hallmark of AAG, although a subgroup of AAG patients may be seronegative. Objectives To assess the occurrence and clinical features of seronegative compared to seropositive AAG. Methods This is a cross-sectional study including 516 consecutive adult patients (age 59.6 ± 12.8 years, FM = 2.21) with histologically proven AAG diagnosed in two Italian academic referral centers over the last 10 years. PCA were detected at AAG diagnosis. Variables related to the dependent variable of interest (i.e.PCA-negativity) were assessed by univariate/logistic regression analysis. Results 109/516 AAG patients were seronegative. The mean age of seronegative AAG patients was significantly higher compared to PCA-positive (65.9 ± 14.1vs57.9 ± 15.1 years; p less then 0.0001). The proportion of patients aged 70-79 and ≥80 years were, respectively, lower for PCA-positivity (5.1vs12.8%;21.3vs38.5%;p less then 0.005). Seronegativity was associated with age ≥50 years (OR2.4;95%CI 1.1-5.2), while for other variables (gender, comorbidities, anemia, atrophy severity) no association was found. In a sub-cohort of 101 AAG patients, PCA levels detected by ELISA were inversely correlated with age at AAG diagnosis (rho=-0.250;p = 0.0118). Conclusion Roughly 20% of patients are seronegative at the time of AAG histological diagnosis and this is more common in elderly individuals.The phylum Apicomplexa has been defined by the presence of the apical complex, a structure composed of secretory organelles and specific cytoskeletal elements. A conspicuous feature of the apical complex in many apicomplexans is the conoid, a hollow tapered barrel structure composed of tubulin fibers. In Toxoplasma gondii, the apical complex is a central site of convergence for calcium-related and lipid-mediated signaling pathways that coordinate conoid protrusion, microneme secretion, and actin polymerization, to initiate gliding motility. Through cutting-edge technologies, great progress has recently been made in discovering the structural subcomponents and proteins implicated in the biogenesis and stability of the apical complex and, in turn, these discoveries have shed new light on the function and evolution of this definitive structure.Background We determined whether postoperative intravenous (IV) iron supplementation could reduce transfusion rate in patients undergoing staged bilateral total knee arthroplasty (TKA). Furthermore, we examined whether hemoglobin (Hb) levels and iron profile differed between patients with and without postoperative IV iron supplementation. Methods This retrospective, comparative cohort study included 126 patients who underwent primary staged bilateral TKA during a single hospitalization. The second TKA was performed at a week's interval. Group iron (n = 65) received IV iron immediately after each surgery, while patients in group no-iron (n = 61) received no iron after surgery. Transfusion rate, change in Hb levels, and iron profile including serum iron, ferritin, total iron binding capacity, and transferrin saturation were evaluated preoperatively; on postoperative days 1, 2, and 4 after the first TKA; and postoperative days 1, 2, 4, and 7, 6 weeks, and 3 months after the second TKA. Results There were no significant differences in Hb levels and transfusion rate following staged bilateral TKA between patients with and without postoperative IV iron supplementation although serum iron profiles were improved in patients with IV iron supplementation. Conclusion Postoperative IV iron supplementation immediately after acute blood loss caused by TKA was not effective in improving the transfusion rate. Therefore, surgeons should use protocols other than postoperative IV iron supplementation for reducing the transfusion rate in patients undergoing staged bilateral TKA in a single hospitalization. Level of evidence III.Background The shift toward outpatient joint arthroplasty is rapidly growing, but concerns still remain on whether certain patients should be excluded from same-day discharge arthroplasty. The purpose of this study is to evaluate whether morbid obesity is a risk factor for perioperative complications after outpatient joint arthroplasty. Methods A retrospective review was performed from 2013 to 2017 of all outpatient primary total hip, total knee, partial knee, and revision hip and knee arthroplasties, yielding a cohort of 4863 patients (5988 arthroplasty procedures). Patients were separated and analyzed based on 2 groups nonmorbidly obese (NMO) (BMI less then 40 kg/m2) and morbidly obese (MO) (BMI ≥ 40 kg/m2). The NMO group consisted of 4870 arthroplasties and the MO group consisted of 1118 arthroplasties. Overnight stays, medical complications, and early perioperative complications were assessed between groups. Results Overnight stays occurred in 5.4% of NMO patients and 9.1% of MO patients (P less then .001), with medical reasons for the overnight stay occurring in 3.2% of NMO and 6.4% of MO patients (P less then .001). Respiratory/sleep apnea was the leading medical reason leading to overnight stay occurring in 4% of MO patients and 0.8% of NMO patients (P less then .001). There was no significant difference between groups in direct facility transfers, emergency room visits/admissions, or medical complications within 90 days. Wound revisions, nonrevision surgery, or revisions within 90 days were significant between groups. Conclusion MO patients did not have an increased risk of 90-day medical complications, readmission, or revisions after outpatient arthroplasty. However, MO patients did have a significantly higher incidence of overnight stay.Methane-oxidizing bacteria (MOB) possess the metabolic potential to assimilate the highly potent greenhouse gas, CH4, and can also synthesize valuable products. Depending on their distinct and fastidious metabolic pathways, MOB are mainly divided into Type I and Type II; the latter are known as producers of polyhydroxyalkanoate (PHA). Despite the metabolic potential of MOB to synthesize PHA, the ecophysiology of MOB, especially under high CH4 flux conditions, is yet to be understood. Therefore, in this study, a rice paddy soil receiving a high CH4 flux from underground was used as an inoculum to enrich MOB using fed-batch operation, then the enriched Type II MOB were characterized. The transitions in the microbial community composition and CH4 oxidation rates were monitored by 16S rRNA gene amplicon sequencing and degree of CH4 consumption. With increasing incubation time, the initially dominant Methylomonas sp., affiliated with Type I MOB, was gradually replaced with Methylocystis sp., Type II MOB, resulting in a maximum CH4 oxidation rate of 1.40 g-CH4/g-biomass/day. The quantification of functional genes encoding methane monooxygenase, pmoA and PHA synthase, phaC, by quantitative PCR revealed concomitant increases in accordance with the Type II MOB enrichment. These increases in the functional genes underscore the significance of Type II MOB to mitigate greenhouse gas emission and produce PHA.Marker genes are essential for gene modification and genome editing of microorganisms. In Aspergillus oryzae, a widely used host for enzyme production, only a few marker genes can be used for positive selection. One of these genes, the pyrithiamine (PT) resistance marker gene thiA, is not useful for CRISPR/Cas9 genome editing because of its unique resistance-conferring mechanism. In this study, a novel PT resistance marker was investigated considering its potential applications in genome editing. A mutant resistant to PT was selected from UV-mutagenized A. oryzae RIB40. Whole genome analysis was conducted on the mutants, and a novel candidate gene for PT resistance was identified. This candidate gene exhibited similarity to the thiamine transporter gene thi9 of Schizosaccharomyces pombe and was designated as thiI. A thiI loss-of-function mutant was generated using the CRISPR/Cas9 genome editing system to investigate its effect on PT resistance. This mutant showed PT resistance and exhibited no growth defect or auxotrophy. The thiI gene was further investigated for its use as a selection marker in genome co-editing. Ribonucleoprotein complex comprising recombinant Cas9 nuclease and sgRNA targeting thiI or another target gene (wA or sreA) was prepared and simultaneously introduced into A. oryzae RIB40. thiI and target gene double loss-of-function mutants were efficiently selected on PT-containing medium. Vorapaxar thiI was shown to be a useful marker gene in A. oryzae for use in genome editing. This study is expected to provide insights, which will promote basic research and industrial applications of A. oryzae.A wealth of studies over several decades has revealed an epigenetic prepattern that determines the competence of cellular differentiation in the developing liver. More recently, studies focused on the impact of epigenetic factors during liver regeneration suggest that an epigenetic code in the quiescent liver may establish its regenerative potential. We review work on the pioneer factors and other chromatin remodelers that impact the gene expression patterns instructing hepatocyte and biliary cell specification and differentiation, along with the requirement of epigenetic regulatory factors for hepatic outgrowth. We then explore recent studies involving the role of epigenetic regulators, Arid1a and Uhrf1, in efficient activation of proregenerative genes during liver regeneration, thus highlighting the epigenetic mechanisms of liver disease and tumor development.Purebred dog breeds provide a powerful resource for the discovery of genetic variants affecting skeletal morphology. Domesticated and subsequently purebred dogs have undergone strong artificial selection for a broad range of skeletal variation, which include both the size and shapes of their bones. While the phenotypic variation between breeds is high, within-breed morphological variation is typically low. Approaches for defining genetic variants associated with canine morphology include quantitative within-breed analyses, as well as across-breed analyses, using breed standards as proxies for individual measurements. The ability to identify variants across the genomes of individual dogs can now be paired with precise measures of morphological variation to define the genetic interactions and the phenotypic effect of variants on skeletal morphology.Objectives Patients with Cystic Fibrosis (CF) suffer from pancreatic insufficiency, lipid malabsorption and gastrointestinal complaints, next to progressive pulmonary disease. Altered mucosal homoeostasis due to malfunctioning chloride channels results in an adapted microbial composition of the gastrointestinal and the respiratory tract. Additionally, antibiotic treatment has the potential to distort resident microbial communities dramatically. This study aims to investigate early life development of the gut microbial community composition of children with CF compared to healthy infants and to study the independent effects of antibiotics taking into account other clinical and lifestyle factors. Study design Faecal samples from 20 infants with CF and 45 healthy infants were collected regularly during the first 18 months of life and microbial composition was determined using 16S rRNA based sequencing. Results We observed significant differences in the overall microbiota composition between infants with CF and healthy infants (p less then 0.
