There is growing evidence that hepatitis E virus (HEV) infection can present with extrahepatic manifestations including neurological disorders. Among these, neuralgic amyotrophy (NA) has been reported to occur in some industrialized countries. We investigated 35 patients with NA and a control group for markers of HEV infection. Acute HEV infection was found in NA patients only and was associated with an inflammatory response in the central nervous system. Shedding of HEV RNA into the cerebrospinal fluid and intrathecal production of anti-HEV IgM occurred in one patient suggesting that HEV is neurotropic...

Background: Basidiobolomycosis is a rare subcutaneous mycosis, which can be mistaken for several other diseases, such as soft tissue tumors, lymphoma, or Buruli ulcer in the preulcerative stage. Microbiological confirmation by PCR for Basidiobolus ranarum and culture yield the most specific diagnosis, yet they are not widely available in endemic areas and with varying sensitivity. A combination of histopathological findings, namely, granulomatous inflammation with giant cells, septate hyphal fragments, and the Splendore-Hoeppli phenomenon, can confirm basidiobolomycosis in patients presenting with painless, hard induration of soft tissue...

Background: Hodgkin lymphoma (HL) is the paradigm of curable disease. This study analyzed the overall survival (OS) of patients with HL and compared their survival between decades and with the expected survival of a general population. Results: The median follow-up was 22 years. The median OS was 33 years. The incidence mortality rate for all causes is 2 per every 100 patients per year. The OS of our cohort at 10 years from diagnosis was 76% (95% CI: 72-79) and 52% at 30 years (95% CI: 48-57)...

Human macrophage migration inhibitory factor (MIF) is a cytokine that plays a role in several metabolic and inflammatory processes. Single nucleotide polymorphism (SNP) -173 G/C (rs755622) on MIF gene has been associated with numerous diseases, such as arthritis and cancer. However, most of the reports concerning the association of MIF with these and other pathologies are inconsistent and remain quite controversial. Therefore, we performed a meta-analysis from 96 case-control studies on -173 G/C MIF SNP and stratified the data according to the subjects geographic localization or the disease pathophysiology, in order to determine a more meaningful significance to this SNP...

Infection with Trypanosoma cruzi in women at reproductive age is associated with congenital transmission and adverse pregnancy outcome. The placenta is a key barrier to infection. We characterized gene expression profiles of term placental environment from T. cruzi seropositive (SP) and seronegative (SN) mothers performing RNA-seq. Nine pools of placental RNA paired samples were used: three from SN and six from SP tissues. Each pool consisted of female/male newborns and vaginal/caesarean deliveries binomials...

OBJECTIVE: To evaluate the association of clinical factors on outcomes in SCI patients undergoing ureteroscopy. Immobility, recurrent urinary tract infection, and lower urinary tract dysfunction contribute to renal stone formation in spinal cord injury (SCI) patients. Ureteroscopy is a commonly utilized treatment modality, however, surgical complication rates and outcomes have been poorly defined. Evidence guiding safe and effective treatment of stones in this cohort remains scarce. METHODS: Records were retrospectively reviewed for SCI patients who underwent ureteroscopy for kidney stones from 1996-2014 at a single institution...

BACKGROUND AND OBJECTIVE: Cervical cancer is an important health problem in our country. It is known that there are several risk factors for this neoplasm, and it has been suggested that cervical microbiome alterations could play a role in the development and progress of cancer. Bacterial vaginosis associated bacteria such as Atopobium vaginae and Gardnerella vaginalis has been suggested as potential risk factor for cervical lesions and cervical cancer. MATERIAL AND METHODS: DNA from 177 cervical scraping samples was studied: 104 belonged to women without cytological or colposcopic alterations and 73 samples from precursor lesions with previous human papillomavirus (HPV) infection history...

Nevoid basal cell carcinoma syndrome (NBCCS), also known as Gorlin syndrome, is a rare multisystemic autosomal dominant disorder typically presenting with cutaneous basal cell carcinomas, multiple keratocysts, and skeletal anomalies. NBCCS is caused by heterozygous mutations in the PTCH1 gene in chromosome 9q22, in the PTCH2 gene in 1p34, or the SUFU gene in 10q24.32. Here, we report on an 18-month-old boy presenting with medulloblastoma, frontal bossing, and multiple skeletal anomalies and his father who has basal cell carcinomas, palmar pits, macrocephaly, bifid ribs, calcification of falx cerebri, and a history of surgery for odontogenic keratocyst...

Bacteria use quorum sensing (QS) to regulate gene expression. We identified a group A Streptococcus (GAS) strain possessing the QS system sil, which produces functional bacteriocins, through a sequential signaling pathway integrating host and bacterial signals. Host cells infected by GAS release asparagine (ASN), which is sensed by the bacteria to alter its gene expression and rate of proliferation. We show that upon ASN sensing, GAS upregulates expression of the QS autoinducer peptide SilCR. Initial SilCR expression activates the autoinduction cycle for further SilCR production...

The proposal that the respiratory complexes can associate with each other in larger structures named supercomplexes (SC) is generally accepted. In the last decade's most of the data about this association came from studies in yeasts, mammals and plants, and information is scarce in other lineages. Here we studied the supramolecular association of the F1 FO -ATP synthase (complex V) and the respiratory complexes I, III and IV of the colorless alga Polytomella sp. with an approach that involves solubilization using mild detergents, n-dodecyl-β-D-maltoside (DDM) or digitonin, followed by separation of native protein complexes by electrophoresis (BN-PAGE), after which we identified oligomeric forms of complex V (mainly V2 and V4 ) and different respiratory supercomplexes (I/IV6 , I/III4 , I/IV)...

BACKGROUND: /Aims: Renal disease is a common cause of morbidity in patients with Bardet-Biedl syndrome (BBS), however the severity of kidney dysfunction is highly variable. To date, there is little information on the pathogenesis, the risk and predictor factors for poor renal outcome in this setting. The present study aims to analyze the spectrum of urinary proteins in BBS patients, in order to potentially identify 1) disease-specific proteomic profiles that may differentiate the patients from normal subjects; 2) urinary markers of renal dysfunction...

Background: The diagnosis of the neglected tropical skin and soft tissue disease Buruli ulcer (BU) is made on clinical and epidemiological grounds, after which treatment with BU-specific antibiotics is initiated empirically. Given the current decline in BU incidence, clinical expertise in the recognition of BU is likely to wane and laboratory confirmation of BU becomes increasingly important. We therefore aimed to determine the diagnostic accuracy of clinical signs and microbiological tests in patients presenting with lesions clinically compatible with BU...

INTRODUCTION: The World Health Organization's (WHO) recommendation of "Treat All" has accelerated the call for differentiated antiretroviral therapy (ART) delivery, a method of care that efficiently uses limited resources to increase access to HIV treatment. WHO has further recommended that stable individuals on ART receive refills every 3 to 6 months and attend clinical visits every 3 to 6 months. However, there is not yet consensus on how to ensure that the quality of services is maintained as countries strive to meet these standards...

The sustainable, selective direct hydroxylation of arenes, such as benzene to phenol is an important research challenge. Mostly thermochemical approaches have been studied, but these still have various drawbacks. An electrocatalytic transformation using formic acid to oxidize benzene and its halogenated derivatives to selectively yield aryl formates that are easily hydrolyzed by water yielding the corresponding phenols is presented. The formylation reaction occurs on a Pt anode in the presence of [Co(III)W12O40]5- as catalyst and Li formate as electrolyte via formation of a formyloxyl radical as the reactive species, which was trapped by a BMPO spin trap and identified by EPR...

Despite treatment of patients with metastatic colorectal cancer (mCRC) with bevacizumab plus chemotherapy, response rates are modest and there are no biomarkers available that will predict response. The aim of this study was to assess if markers associated with three interconnected cancer-associated biological processes, specifically angiogenesis, inflammation and oxidative damage, could stratify the survival outcome of this cohort. Levels of angiogenesis, inflammation and oxidative damage markers were assessed in pre-bevacizumab resected tumour and serum samples of mCRC patients by dual immunofluorescence, immunohistochemistry and ELISA...
