AIMS: Plasmablastic plasma cell myeloma (PPCM) is a rare morphological presentation of multiple myeloma and can resemble plasmablastic lymphoma (PBL), an HIV related lymphoid neoplasm, morphologically and immunophenotypically. We retrospectively searched for factors that could help differentiate these two entities. METHODS: We used Clinical Looking Glass (CLG), a data mining tool, to identify patients with a diagnosis of either PPCM or PBL with a CD117 test performed...

BACKGROUND: Intraperitoneal adhesions cause significant morbidity. They occur after peritoneal trauma, which induces oxidative stress with production of inflammatory cytokines, peroxidized proteins (carbonyls) and lipids (aldehydes). This study aimed to investigate if carbazate-activated polyvinyl alcohol (PVAC), an aldehyde-carbonyl inhibitor, can reduce intraperitoneal adhesions in an experimental model. MATERIAL AND METHODS: Male Sprague-Dawley rats (n=110) underwent laparotomy, cecal abrasion and construction of a small bowel anastomosis...

Tuberculosis (TB) affects people globally and is being reconsidered as a serious public health problem in China. Reliable forecasting is useful for the prevention and control of TB. This study proposes a hybrid model combining autoregressive integrated moving average (ARIMA) with a nonlinear autoregressive (NAR) neural network for forecasting the incidence of TB from January 2007 to March 2016. Prediction performance was compared between the hybrid model and the ARIMA model. The best-fit hybrid model was combined with an ARIMA (3,1,0) × (0,1,1)12 and NAR neural network with four delays and 12 neurons in the hidden layer...

Graves' disease (GD) and Hashimoto's disease (HD) are autoimmune thyroid diseases (AITDs). Prognosis of AITDs varies in each patient. Toll-like receptors (TLRs) are pattern-recognition receptors that activate signaling pathways involved in the production of proinflammatory cytokines. UNC93B1 is a transcription factor of TLR7 and TLR9. In this study, we examined the association of TLR expression and TLR and UNC93B1 polymorphisms with the development and prognosis of AITDs. The ratio of intracellular TLR7 (iTLR7) and iTLR9 intensities in B cells was lower in patients with GD in remission than in patients with intractable GD (p = 0...

BACKGROUND: Low-dose spinal anaesthesia is a safe and reliable anaesthesia technique in outpatient perianal surgery. Regarding its short duration of action and its trend to hyperbaric characteristics, plain chloroprocaine 10 mg/ml seems to be ideal to perform low-dose spinal anaesthesia. The aim of this trial was to determine the optimal dosage of chloroprocaine for this indication. METHODS: Hundred and twenty patients undergoing perianal surgery were enrolled and randomly allocated to receive 10, 20 or 30 mg of chloroprocaine 10 mg/ml intrathecally...

BACKGROUND: Sulfonamide hypersensitivity has a high incidence in HIV infection and correlates with low CD4+ counts, but the mechanisms are not understood. The aims of this study were to determine whether trimethoprim/sulfamethoxazole (TMP/SMX) led to SMX adduct formation, immunogenicity, or signs of drug hypersensitivity in SIV-infected rhesus macaques, and whether differences in antioxidants, pro-inflammatory mediators, or SMX disposition were predictive of drug immunogenicity. METHODS: Nine macaques chronically infected with SIVmac239 and 7 non-infected controls were studied...

OBJECTIVE: Some studies suggest that pulse pressure (PP) and renal resistive index (RI) could be predictive of the risk of death; however, whether they also predict graft loss is debated. It was recently demonstrated that RI reflects large artery arterial stiffness as PP does but RI is also affected by alteration in renal microcirculation alteration. Finally, the respective predictive value of these 2 parameters considered together on graft loss and death is unknown. DESIGN AND METHOD: Cohort study of consecutive patients who received a renal graft in Tours from 1985 to 2014 in whom PP and RI were measured at 3 months...

BACKGROUND: Air leak is a common problem in pulmonary surgical procedures. In this study, we evaluated the efficacy and safety of gelatin glue (cross-linked with glutaraldehyde) in a rat model of lung air leak. METHODS: A model of pulmonary fistula was created in the rat lung with the use of a needle. The fistula was then sealed with either gelatin glue (group A), fibrin glue (group B), or fibrin glue with a polyglycolic acid sheet (group C). The seal breaking pressures were measured for each group, and the results were compared...

INTRODUCTION: Breast cancer is associated with a 3-4 fold increased risk of VTE. These patients have a 4-fold lower survival than those remaining free of VTE, implying VTE is a surrogate marker for aggressive cancer. Tumour expression of thrombin pathway markers are increased in the oestrogen receptor negative (ER-), high Ki67, more aggressive breast cancer subtypes. In in vitro and in vivo studies, the thrombin pathway promotes cancer growth and metastases, highlighting the potential role of the thrombin pathway as a therapeutic target in cancer...

The patient was a 15-year-old adolescent girl with a chief complaint of intermittent pain and clicking at her right distal radioulnar joint, after having fractured her forearm 5 months previously. Radiographs of the patient's forearm indicated a midshaft radial deformity. Given the patient's pain and limited range of motion, computed tomography imaging was requested to assess whether the midshaft malunion resulted in distal radioulnar joint instability and to plan the corrective osteotomy.

BACKGROUND: Angiogenesis plays a pivotal role in malignant tumor progression. The count of blood microvessels of the tumor has been recognized as an indicator of malignant potential of the tumors and provides the ability to predict tumors recurrence. The role endoglin in the Dukes B rectal cancer is still unexplored. The aims of this study were to examine immunohistochemical expression of endoglin in resected rectal cancer and investigate the relationship of tumor recurrence and other clinicopathological variables to the endoglin-assessed microvessel density of the tumor tissue and distal resection margins...

OBJECTIFS: Certaines études ont suggéré que la pression pulsée (PP) et l'index de résistance intra-rénale (IR) pouvaient être prédictifs du risque de décès, mais leur impact sur la survie du greffon est controversé. Il a été montré que l'IR était un reflet de la rigidité artérielle des gros vaisseaux comme la PP, mais aussi de l'état de la microcirculation rénale. Cependant, l'impact respectif de ces 2 paramètres sur les risques de décès et de perte de greffon n'est pas connu, et a été l'objet de cette étude...

Solid Phase Extraction Spectroscopy (SPES) developed in this paper is a technique to measure spectrum directly on the solid phase material where the analytes are concentrated in SPE process. Membrane enrichment and UV-Visible spectroscopy were utilized to fulfill SPES, and multivariate calibration method of partial least squares (PLS) was used to simultaneously detect the concentrations of trace cobalt (II) and zinc (II) in water samples. The proposed method is simple, sensitive and selective. The complexes of analyte ions were collected on the cellulose acetate membranes via membrane filtration after the complexation reaction with 1-2-pyridylazo 2-naphthol (PAN)...

Anaplasma phagocytophilum, the causative agent of Human Granulocytic Anaplasmosis (HGA), is an obligately intracellular α-proteobacterium that is transmitted by Ixodes spp ticks. However, the pathogen is not transovarially transmitted between tick generations and therefore needs to survive in both a mammalian host and the arthropod vector to complete its life cycle. To adapt to different environments, pathogens rely on differential gene expression as well as the modification of proteins and other molecules...

T cell immunoglobulin- and mucin-domain-containing molecule-3 (Tim-3) has been shown to play an important role in mediating NK-cell function in human diseases. However, the relationship between Tim-3 expression in natural killer (NK) cells and human lung adenocarcinoma remains unclear. We therefore investigated the expression of Tim-3 in NK cells and explored the effect of Tim-3 blockade on NK cell-mediated activity in human lung adenocarcinoma. Upregulated expression of Tim-3 on CD3-CD56+ cells (P<0.05) and CD3-CD56(dim) cells (P<0...
