Mycoplasma gallisepticum causes respiratory diseases and reproduction disorders in turkeys and chickens. The infection has considerable economic impact due to reduced meat and egg production. Because elimination programs are not feasible in a large number of poultry farms, vaccination remains the only effective measure of disease control.Differentiating vaccine strains from field isolates is necessary in the control of vaccination programs and diagnostics. The aim of this study was to develop a polymerase chain reaction (PCR) based mismatch amplification mutation assay (MAMA) for the discrimination of K vaccine strain (K 5831, Vaxxinova Japan K.K.).After determining the whole genome sequence (WGS) of the K strain, primers were designed to detect seven different vaccine-specific single nucleotide polymorphisms (SNPs). After evaluating preliminary results, the MAMA-K-fruA test detecting a single guanine-adenine substitution within the fruA gene (G88A) was found to be the most applicable assay to distinguish the K vaccine strain from field isolates.The detected K strain-specific SNP showed genetic stability after serial passage in vitro, but this stability test still needs to be evaluated in vivo as well, investigating a large number of K strain re-isolates. The MAMA-K-fruA assay was tested on a total of 280 culture and field samples. The designed assay had 102 and 103 template copy number/µl sensitivity in melt-curve analysis based and agarose-gel based assays, respectively, and showed no cross reaction with other avian Mycoplasma species. The new MAMA provides a time- and cost-effective molecular tool for the control of vaccination programmes and for diagnostics.Background Although decongestive physiotherapy combined with diuretics may be efficient in limb edemas, no such therapy has been described in the context of anasarca. Case Description A bedbound 62-year-old man with stage IV pancreatic cancer, presenting with progressing severe dyspnea at rest and anasarca, was admitted to the free-standing hospice 3 weeks after receiving nab-paclitaxel with gemcitabine. Two weeks before admission, oral loop and potassium-sparing diuretics were started for bilateral lower limb edema, which progressed to anasarca even though the drug dose was increased. Hypotension hindered further dose escalation of diuretics. Supportive multicomponent bandage compression on both legs with concurrent intravenous furosemide in hypersaline infusion was implemented with good clinical toleration. Afterward, the loop diuretic dose was increased, and supplemented with dexamethasone. A spectacular edema decrease and marked dyspnea improvement with 19 kg body weight reduction were observed within 7 days. Furosemide was switched to oral route and the patient was discharged needing only occasional assistance in daily living. Conclusion Compression bandaging with diuretic therapy may be considered even in advanced generalized edemas; however, further studies are needed to determine the adequate therapeutic regime.Objective Morning stiffness (MS) is characteristic of rheumatoid arthritis (RA). Despite its association with functional disability, the extent to which local inflammatory processes contribute to this symptom is unknown. Magnetic resonance imaging (MRI)-detected tenosynovitis of small joints is recognized as an early feature of RA, which is also associated with functional impairments. It has been proposed that tenosynovitis contributes to MS. Therefore, we assessed the relationship between MS and MRI-detected inflammation, in particular tenosynovitis.Method In total, 286 consecutive patients newly presenting with undifferentiated arthritis and RA underwent contrast-enhanced 1.5 T MRI of (2-5) metacarpophalangeal, wrist, and (1-5) metatarsophalangeal joints. Scans were scored for tenosynovitis according to Haavardsholm, and for synovitis by Rheumatoid Arthritis Magnetic Resonance Imaging Scoring (RAMRIS). MS was dichotomized as ≥ 60 min or not. Associations between MS and tenosynovitis/synovitis were tested with logistic regression, data were categorized (solitary or simultaneous presence of synovitis/tenosynovitis), and the presence of an additive interaction was assessed.Results MS was present in 40% of patients. Tenosynovitis was more often present in patients with MS than without MS [80% vs 65%, odds ratio (OR) 2.11, 95% confidence interval (1.21;3.69)]. Synovitis was more often present in patients with MS [58% vs 44%, OR 1.79 (1.11;2.91)]. In categorized analyses, concurrent synovitis and tenosynovitis had the largest association [OR 2.43 (1.30;4.54)], in contrast to solitary synovitis [OR 0.85 (0.21;3.47)]. The additive interaction was non-significant. The variance explained in all analyses was small (range 4-5%).Conclusion Tenosynovitis, combined with synovitis, at small joints is associated with MS and contributes to the pathophysiology of MS.Polysaccharide from Schisandra chinensis has the effect of lowering blood glucose and improving insulin resistance (IR). However, its underlying mechanism remains unclear. In this study, a rat model of type 2 diabetes (T2D) was created to explore whether S. chinensis acidic polysaccharide (SCAP) would improve the IR in T2D rats by inhibiting inflammation. A combination of a high-fat diet and low dose of streptozotocin (STZ, 30 mg/kg, intraperitoneally) were administered to rats for establishing the T2D model. Then, these T2D rats were orally administered with SCAP (25, 50, or 100 mg/kg) for 8 weeks. The results indicated that SCAP significantly lowered the fasting blood glucose, elevated the fasting insulin, and improved glucose tolerance. SCAP also decreased the serum interleukin-1β (IL-1β), interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), C-reactive protein (CRP), and nuclear factor-κB (NF-κB) levels, as well as their mRNA expression in the liver tissue. Further, SCAP significantly inhibited the upregulation of phosphorylated c-Jun N-terminal kinase (p-JNK) and NF-κB protein, and it increased phosphorylated insulin receptor substrate-1 (p-IRS-1), phosphorylated phosphatidylinositol 3-kinase (p-PI3K), and phosphorylated protein kinase B (p-AKT) protein expression levels significantly. These results suggest that SCAP improves the IR in T2D rats by inhibiting inflammation.In the past decade, Mexican coasts have received an enormous influx of macroalgae species, producing serious environmental and public health concerns. Here, we developed a green methodology to generate a new polymer from the lignin contained in the macroalgae. The methodology consists in lignin extraction-by-boiling and its subsequent polymerization with a laccase-like enzyme from the green algae Tetraselmis gracilis (Tg-laccase). Mass spectrometry revealed the presence of guaiacyl (G), p-hydroxyphenyl (H), and sinapyl alcohol as the main monolignols in the lignin from Sargassum sp. On the other hand, MALDI-TOF spectra shows an increase in the size of the lignin chain after enzymatic polymerization process with Tg-laccase. Besides, the characterization of the novel polymer -using 1H NMR, FTIR, SEC-FPLC, and UV/Vis- allowed establishing that during the polymerization process there is a decrease in the number of phenolic groups as well as loss of aromatic protons, which allowed proposing a polimerizacion mechanism. This methodology could be promising in the development of a new lignin-based polymer and would open a new direction for the environmental management of the macroalgae on the Mexican beaches.Background The prevalence of extended-spectrum β-lactamase (ESBL)-producing Enterobacterales (ESBL-E) and carbapenemase-producing Enterobacterales (CPE) is now disseminated worldwide. This study aims to describe the prevalence of ESBL and CPE fecal carriage in colorectal cancer patients. Methods All patients admitted to the oncology service of Amizour hospital (Algeria) for colorectal cancer chemotherapy from March to May 2019 were screened for ESBL-E or CPE fecal carriage. After culturing on chromogenic media, the presumptive colonies were identified by mass spectroscopy. Antibiotic susceptibility testing was performed according to the European Committee on Antimicrobial Susceptibility Testing. The β-lactamases encoding genes and plasmid-mediated quinolone-resistant genes were screened by PCR and sequencing. Results ESBL-E strains were recovered from rectal swabs in 6 patients (14.3%) and only 1 patient (2.4%) was found a carrier for OXA-48-producing Klebsiella pneumoniae. The most frequently encountered species among ESBL-E was Escherichia coli (n = 5), followed by K. pneumoniae (n = 1). PCR and sequencing showed that four isolates harbored the blaCTX-M-15 gene and two strains harbored the blaCTX-M-14 gene. Selleck PK11007 Also, one strain of K. pneumoniae was found to harbor both qepA and qnrS genes. Conclusion This study highlighted the fecal carriage of ESBL-E and OXA-48-producing Enterobacterales strains in colorectal cancer patients.Objectives The aim was to assess the potential advantage of combined genotypic testing with phenotypic antimicrobial susceptibility testing (AST) to detect AmpC β-lactamases (AmpC) and extended-spectrum β-lactamases (ESBL) producing Enterobacteriaceae isolated from blood cultures in a pediatric population. Materials and Methods All first-time Enterobacteriaceae isolates recovered from blood cultures of pediatric patients at the Cincinnati Children's Hospital Medical Center between January 2017 and December 2018 were evaluated. The Check-MDR CT103XL β-lactamase assay was used to determine the presence of AmpC and ESBL, while AST was performed using the VITEK 2 platform. Phenotypic ESBL resistance was defined by resistance to either ceftriaxone or ceftazidime using Clinical and Laboratory Standards Institute breakpoints, while combined cefoxitin resistance with ceftriaxone or ceftazidime resistance was used to detect AmpCs (as per European Committee on Antimicrobial Susceptibility Testing standards). Results Overall, there were 170 isolates. Genotypically, 21 (12.4%) had AmpC and 18 (10.6%) had ESBL genes detected. Phenotypically, 11 (6.5%) isolates were AmpC and 26 (15.3%) were ESBL producing organisms. Genotypic testing identified an additional 14 AmpC and two ESBL isolates that failed to meet phenotypic criteria. Conclusions Using combined genotypic and phenotypic methods to detect AmpC and ESBL producing organisms increased the identification of resistant organism and provided potentially clinical relevant data to guide the treatment of resistant organisms.Background Laparoscopic sleeve gastrectomy (LSG) is now one of the most common surgical procedures worldwide. It was initially defined for staged procedures in super or super-super obese, or in very complex patients. The primary objective of the study was to assess the safety of LSG for morbid-obese (MO, body mass index [BMI] >40 kg/m2) and super-morbid-obese (SMO, BMI >50 kg/m2) patients in terms of operative and postoperative complication rate. Methods This study involves a retrospective analysis of a prospective database that included data for patients who underwent LSG, between 2008 and 2017, in our institution. All LSG procedures were performed by the same two certified bariatric surgeons following a standardized surgical procedure. Data on operative and postoperative complications were collected for all the patients. Results A total of 713 patients were included in the study 495 (61.42%) were MO (mean age 46.06 ± 11.98 years) and 218 (30.58%) were SMO (mean age 42.98 ± 11.17 years). There were no significant differences between both groups in terms of minor and major postoperative complications or long-term complications.
