Human immunodeficiency virus (HIV)-associated neurocognitive disorders are the main cause of cognitive decline and dementia in people living with HIV (PLHIV). However, extensive workup should be done in patients with rapidly progressive dementia (RPD) and HIV, especially when secondary infection in the central nervous system (CNS) is ruled out. Sporadic Creutzfeldt-Jakob disease (sCJD) is the main cause of RPD in non-HIV patients. It is a fatal neurodegenerative condition caused by prions that mainly affects elderly patients. Our objective is to describe two cases of PLHIV presenting with controlled infections and sCJD, and to review the literature. Our patients were younger than expected for sCJD and one of them had a longer disease course. As aging is expected to occur earlier in PLHIV, sCJD must be excluded in younger PLHIV presenting with RPD and without CNS infection.COVID-19 is an infectious disease caused by the recently discovered coronavirus SARS-Cov-2. The disease became pandemic affecting many countries globally, including Brazil. Considering the expansion process and particularities during the initial stages of the epidemic, we aimed to analyze the spatial and spatiotemporal patterns of COVID-19 occurrence and to identify priority risk areas in Minas Gerais State, Southeast Brazil. An ecological study was performed considering all data from human cases of COVID-19 confirmed from the epidemiological week (EW) 11 (March 08, 2020) to EW 26 (June 27, 2020). Crude and smoothed incidence rates were used to analyze the distribution of disease patterns based on global and local indicators of spatial association and space-time risk assessment. Positive spatial autocorrelation and spatial dependence were found. Our results suggest that the metropolitan region of the State capital Belo Horizonte (MRBH) and Vale do Rio Doce mesoregions, as major epidemic foci in the beginning of the expansion process, have had important influence on the dispersion of SARS-CoV-2 in Minas Gerais State. Triangulo Mineiro/Alto Paranaiba region presented the highest risk of infection. Caspase-dependent apoptosis In addition, six statistically significant spatiotemporal clusters were identified in the State, three at high risk and three at low risk. Our findings contribute to a greater understanding of the space-time disease dynamic and discuss strategies for identification of priority areas for COVID-19 surveillance and control.We analyzed the clinical features and risk factors of candidemia due to C. parapsilosis (n=104) in the intensive care unit of a tertiary hospital over six years. This was a monocentric, retrospective study of candidemia, conducted from January 2013 to March 2019. Epidemiological characteristics, clinical features, invasive procedures, laboratory data and outcomes of 267 patients with candidemia were analyzed to determine risk factors of candidemia due to C. parapsilosis. Sixty-three cases of C. albicans and 204 cases of non-C. albicans Candida (NCAC) species were included, the latter was composed of 104 cases of C. parapsilosis and 100 cases of non-C. albicans species (46 cases of C. tropicalis, 22 cases of C. glabrata, 23 cases of C. guilliermondii, 5 cases of C. krusei and 4 cases of C. lusitaniae), suggesting that C. parapsilosis was the predominant Candida species isolated from cases of candidemia. A binary multivariate logistic regression analysis showed that APACHE II scores, central venous catheterization and the use of broad-spectrum antibiotics were closely related to C. parapsilosis candidemia, with OR values of 1.159, 3.913 and 2.217, respectively. In conclusion, we found that C. parapsilosis was the main pathogen among the NCAC candidemia in the ICU patients. APACHE II scores, central venous catheterization and the use of broad-spectrum antibiotics were independent risk factors for the occurrence of C. parapsilosis candidemia, which may provide data to support the early introduction of anti-fungal therapy.The emergence and spread of extensively drug-resistant tuberculosis (XDR-TB) is a serious threat to global health. Therefore, its rapid diagnosis is crucial. The present study aimed to characterize mutations conferring resistance to second line drugs (SLDs) within multidrug Mycobacterium tuberculosis (MDR-MTB) isolates and to estimate the occurrence of XDR-TB in Casablanca, Morocco. A panel of 200 MDR-TB isolates was collected at the Pasteur Institute between 2015-2018. Samples were subjected to drug susceptibility testing to Ofloxacin (OFX), Kanamycin (KAN) and Amikacin (AMK). The mutational status of gyrA, gyrB, rrs, tlyA and eis was assessed by sequencing these target genes. Drug susceptibility testing for SLDs showed that among the 200 MDR strains, 20% were resistant to OFX, 2.5% to KAN and 1.5% to AMK. Overall, 14.5% of MDR strains harbored mutations in gyrA, gyrB, rrs and tlyA genes. From the 40 OFXR isolates, 67.5% had mutations in QRDR of gyrA and gyrB genes, the most frequent one being Ala90Val in gyrA gene. Of note, none of the isolates harbored simultaneously mutations in gyrA and gyrB genes. In eight out of the 200 MDR-TB isolates resistant either to KAN or AMK, only 25% had A1401G or Lys89Glu change in rrs and tlyA genes respectively. This study is very informative and provides data on the alarming rate of fluoroquinolone resistance which warrants the need to implement appropriate drug regimens to prevent the emergence and spread of more severe forms of Mycobacterium tuberculosis drug resistance.We report a rare case of an infective endocarditis by Aerococcus spp in a bioprosthetic aortic valve following a prostate biopsy, in an asymptomatic adult with no additional risk factor for prostate cancer, excepting for age. The diagnosis was based on the presence of vegetations on the bioprosthesis seen on the echocardiogram, positive blood cultures and fever, and a favorable clinical outcome following the treatment with ceftriaxone and gentamicin.Dengue virus, the etiological agent of dengue fever (DF) occurs in four genetically distinct serotypes (DENV1-4), being transmitted by female Aedes mosquitoes. DF incidence is increasing in Brazil, following vector dispersal, proliferation and DENV serotypes introduction, co-circulation and substitution. Medium- and small-sized cities in Sao Paulo State, such as Marilia (Midwest region), have been affected by huge epidemics. To understand the evolution of DENV epidemics in medium-sized cities, in this study a historical data on DENV incidence (2000-2015) in Marilia, was evaluated. Previous studies disclosed regional and specific DF outcomes associated with 2007 outbreak in that city, when co-circulating DENV1 and DENV3 presented different hematological profiles. In this study, characteristics of 2007 DENV epidemics were compared to the epidemiological, hematological and demographic outlines of the major outbreak of DENV1 in Marilia in 2015. DENV1 genetic diversity was assessed through capsid and pre-membrane junction encoding gene (CprM) sequencing.
