Genomic evidence of gut population diversity translocation in leukemia patients.

a commensal species of the human gut, is an opportunistic pathogen that can reach extra-intestinal compartments, including the bloodstream and the bladder, among others. In non-immunosuppressed patients, purifying or neutral evolution of populations has been reported in the gut. Conversely, it has been suggested that when migrating to extra-intestinal compartments, genomes undergo diversifying selection as supported by strong evidence for adaptation.

Optimization of Mycobacterium tuberculosis DNA processing prior to whole genome sequencing.

The process of whole genome sequencing of the Mycobacterium tuberculosis complex is dependent on complete the inactivation of the strain and subsequent DNA extraction. The objective of this study was to optimise the two steps. Firstly, the efficacy of Triton X-100 as a solvent for the inactivation step was evaluated.

Dermatological Conditions Seen in Kidney Transplant Recipients: Prevalence and Risk Factors.

Objectives: In kidney transplant, the use of immunosuppressive drugs, indispensable to avoid organ rejection, implies an increased risk of several infectious and neoplastic diseases. Cutaneous infections have a high incidence in kidney transplant recipients and are diagnosed in 55% to 97% of these patients. The objectives of this study were to identify the most frequent skin diseases and their clinical risk factors within a population of kidney transplant recipients.

Prevalence and Predictive Factors of Urinary Tract Infection in Kidney Transplant Recipients: A 10-Year Study.

Objectives: Urinary tract infections are the main infectious complications among kidney transplant recipients and are considered as a potential risk factor for poor graft outcomes. However, the risk factors of urinary tract infections are controversial. The purpose of our study was to estimate the incidence and predisposing factors of urinary tract infections in patients undergoing kidney transplant in our teaching hospital of Sahloul, Tunisia.

Objective: To evaluate the accuracy of 4 equations validated for the general population to determine resting energy expenditure (REE) in polio survivors.

Design: A descriptive, ambispective, single-center observational cohort study of minimal risk care.

Setting: Tertiary university care hospital.

Comprehensive Analysis of Hepatitis Delta Virus Assembly Determinants According to Genotypes: Lessons From a Study of 526 Hepatitis Delta Virus Clinical Strains.

Human hepatitis Delta virus (HDV) infection is associated to the most severe viral hepatic disease, including severe acute liver decompensation and progression to cirrhosis, and hepatocellular carcinoma. HDV is a satellite of hepatitis B virus (HBV) that requires the HBV envelope proteins for assembly of HDV virions. HDV and HBV exhibit a large genetic diversity that extends, respectively to eight (HDV-1 to -8) and to ten (HBV/A to/J) genotypes.

Antegrade double-J stent placement for the treatment of malignant obstructive uropathy: A retrospective cohort study.

Background: Ureteral double- J stent is usually inserted by retrograde approach to treating obstructed upper urinary tract. The antegrade approach, can be suitable alternative in certain situations without general or spinal anesthesia. The present study demonstrates the indications, success rate, and complications of this approach in treatmenting malignant obstructive uropathy.

Variable In Vivo Hepatitis D Virus (HDV) RNA Editing Rates According to the HDV Genotype.

Human hepatitis delta virus (HDV) is a small defective RNA satellite virus that requires hepatitis B virus (HBV) envelope proteins to form its own virions. The HDV genome possesses a single coding open reading frame (ORF), located on a replicative intermediate, the antigenome, encoding the small (s) and the large (L) isoforms of the delta antigen (s-HDAg and L-HDAg). The latter is produced following an editing process, changing the amber/stop codon on the s-HDAg-ORF into a tryptophan codon, allowing L-HDAg synthesis by the addition of 19 (or 20) C-terminal amino acids.

Incidental chronic lymphocytic leukemia diagnosed following radical prostatectomy for prostate cancer: A case report.

Background: chronic lymphocytic leukemia (CLL) patients have a high risk of occurrence of secondary cancers. This risk is three times higher for all cancers and eight times higher for skin cancer. The coexistence of CLL and adenocarcinoma of the prostate is rare.

Paraplegia due to medullary compression caused by a large cell neuroendocrine carcinoma of the urinary bladder: A case report.

Background: Neuroendocrine carcinomas of the urinary bladder are rare tumors, estimated at less than 1% of urinary bladder malignancies. They are mainly represented by small cell neuroendocrine carcinoma, while large cell neuroendocrine carcinoma (LCNEC) is rarely reported.

Case Presentation: We report a case of a 49-year-old man presenting paraplegia caused by a metastatic urinary bladder LCNEC, which was managed with palliative external beam radiotherapy (EBRT) associated with MVAC chemotherapy, including methotrexate, vinblastine sulfate, doxorubicin hydrochloride (Adriamycin), and cisplatin.

Assessment of Tunisian acceptance to participate in a Clinical Trial.

"CT" clinical trials are medical research studies to determine whether different treatments are effective and safe. Some trials involve patients and other trials involve healthy volunteers. This survey aims to assess CT knowledge and the acceptance to participate to CT of Tunisian citizen.

Proposition of a safe Mycobacterium tuberculosis complex denaturation method that does not compromise the integrity of DNA for whole-genome sequencing.

Whole-genome sequencing plays now a leading role in epidemiologic studies of tuberculosis. DNA extraction of Mycobacterium tuberculosis complex (MTBC) requires complete inactivation of the strains, to be handled for further molecular procedures. In this study we compared two chloroform-based denaturation methods (one with a step of heat killing, one without) to a traditional heat inactivation method.

Prediction of methicillin-resistant Staphylococcus aureus bloodstream infection: do we need rapid diagnostic tests?

Staphylococcus aureus (SA) is the leading cause of bloodstream infection (BSI). The incidence of methicillin-resistant SA (MRSA) has decreased in France and Europe since one decade. Early and precise prediction of methicillin susceptibility is needed to improve probabilistic antibiotic therapy of MRSA-BSI.

Performance Characteristics of a New Consensus Commercial Kit for Hepatitis D Virus RNA Viral Load Quantification.

Hepatitis D virus (HDV) is responsible for fulminant hepatitis and liver failure and accelerates evolution toward cirrhosis and hepatocellular carcinoma in hepatitis B virus (HBV)-infected patients. To date, treatment relies upon long-term administration of pegylated alpha-interferon with a sustained virological response in 30% of the patients. Very recently, new, promising anti-HDV therapies have been developed and are already being used in clinical trials.

Variation of the chemical composition and antimicrobial activity of the essential oils of natural populations of Tunisian Daucus carota L. (Apiaceae).

The essential oils of Daucus carota L. (Apiaceae) seeds sampled from ten wild populations spread over northern Tunisia were characterized by GC-FID and GC/MS analyses. In total, 36 compounds were identified in the D.

Simulation approach to coincidence summing in γ-ray spectrometry.

Some of the radionuclides used for efficiency calibration of a HPGe spectrometer are subject to coincidence-summing (CS) and account must be taken of the phenomenon to obtain quantitative results when counting samples to determine their activity. We have used MCNPX simulations, which do not take CS into account, to obtain γ-ray peak intensities that were compared to those observed experimentally. The loss or gain of a measured peak intensity relative to the simulated peak is attributed to CS.
