BACKGROUND Outcomes of HIV-positive pregnant patients admitted to intensive care units (ICUs) are controversial. OBJECTIVE To determine maternal and fetal outcomes of HIV-positive patients admitted to ICUs. METHODS Pregnant patients admitted to ICUs were enrolled in the study. On admission, they were classified as having low (<50%) or high (≥50%) risk of death by GRAMPT stratification score...
The effect of variously fluorine-substituted β-methyl-β-nitrostyrenes on their antimicrobial activity was investigated. Their efficacy was determined by minimum inhibition concentration (MIC) in cultures of Gram positive and Gram negative bacteria and a fungus. Highest activity against the Gram negative bacterium, E.coli, was achieved with 4-fluorine-aryl substituted β-methyl-β-nitrostyrenes, w...
Investigations of noninvasive prenatal screening for aneuploidy by analysis of circulating cell-free DNA (cfDNA) have shown high sensitivity and specificity in both high-risk and low-risk cohorts. However, the overall low incidence of aneuploidy limits the positive predictive value of these tests. Currently, the causes of false positive results are poorly understood. We investigated four pregna...
We demonstrated previously that CD45RA(+) CD4(+) T cells are infected primarily by syncytium-inducing (SI) HIV-1 variants, whereas CD45RO(+) CD4(+) T cells harbor both non-SI (NSI) and SI HIV-1 variants. Here, we studied evolution of tropism for CD45RA(+) and CD45RO(+) CD4(+) cells, coreceptor usage, and molecular phylogeny of coexisting NSI and SI HIV-1 clones that were isolated from four pati...
Background: The Multi state Markov models have extensively application with categorization of laboratory marker of CD4 cells for evaluation of HIV disease progression. These models with different states result in different effects of covariates and prediction of HIV disease trend. The main purpose of this study was comparison of four and five states models with the three- state in order to sele...
Although linear trend removing has often been implemented as a routine preprocessing step in resting-state functional magnetic resonance imaging (RS-fMRI) data analysis, the spatial distribution of the magnitude of linear trend is still unclear. Further, it is interesting whether there will be any difference of the linear trend magnitude between different resting-states. For the first aim, we a...
BACKGROUND The clinical significance of blood lead levels (BLLs) in chronic peritoneal dialysis (CPD) patients was undetermined prior to this study. METHODS A total of 315 patients on CPD were included in this 18-month prospective study. BLLs measured at baseline were categorized according to a BLL tertile of high (>8.66 microg/dL), middle (5.62-8.66 microg/dL) and low (<5.62 microg/dL) for c...
The cryosphere is an essential part of the earth system for understanding climate change. Components of the cryosphere, such as ice sheets and sea ice, are generally decreasing over time. However, previous studies have indicated differing trends between the Antarctic and the Arctic. The South Pole also shows internal differences in trends. These phenomena indicate the importance of continuous o...
Migration is topical in many counties, and attitudes towards immigration ethnic diversity are volatile. In our longitudinal “Diversity Barometer”, we have studied changes Swedes’ Sweden since 2005, using a postal questionnaire sent to random sample of the Swedish population aged 18–75. this article, analyzed data from 2020 (n = 1035) comparison with previous Diversity Barometer surveys 2005 201...
OBJECTIVE To examine whether the clinical severity of cervical dystonia (CD) significantly correlates with (18)F-fluorodeoxyglucose positron emission tomography/computed tomography ((18)F-FDG PET/CT) findings as well as to determine the threshold of the clinical severity of CD for positive (18)F-FDG PET/CT study findings. METHODS Forty-seven subjects with torticollis as one of the symptoms of...
