Chronic Kidney Disease as a Risk Factor for Heart Failure With Preserved Ejection Fraction

Heart failure (HF) and chronic kidney disease (CKD) co-exist, and it is estimated that about 50% of HF patients suffer from CKD. Although studies have been performed on the association betwee

Experimental evaluation of scaphoid X-series, carpal box radiographs, planar tomography, computed tomography, and magnetic resonance imaging in the diagnosis of scaphoid fracture

Aim: In this study, we evaluated scaphoid X-series, Carpal Box radiographs (longitudinal and transverse), planar tomography, computed tomography (CT), and magnetic resonance imaging (MRI) in the diagnosis of scaphoid fracture. The aim of this study was to evaluate the planar technique in the diagnosis of scaphoid fracture. The use of planar tomography, CT, and MRI was to see whether these methods are useful in the diagnosis of scaphoid fracture when other diagnostics modalities remains negative. Methods: Twenty- eight embalmed human cadaver specimens were used, in 23 of which fractures of the scaphoid were produced mechanically. Scaphoid X-series, Carpal Box posterior-anterior radiographs in ulnar deviation (X-CB), Carpal Box posterior-anterior views with the hand in 15-degree supination and ulnar deviation (X-CB 15-degree) were acted in all specimens, CT in eight wrists, planar tomography in seven wrists, and MRI in five wrists. The anatomic analysis of the specimens was used as the gold standard for comparison. Scaphoid X-series, Carpal Box radiographs, and planar tomography were judged independently and in a blind fashion by six observers, and CT and MRI were also judged independently and in a blind fashion by three radiologists. The observers were asked if they could recognize a scaphoid fracture. The agreement among the six observers for the scaphoid X-series and X-CB was measured. Results: In the 23 fractured wrists, scaphoid X-series, X-CB, X-CB 15-degree, was true positive in 12, 14, and 15 wrists, respectively, whereas these methods were true negative in cadaver wrists 1, 3, and 5. CT was true positive in five of five fractured wrists and true negative in three of three negative wrists. Planar tomography was true positive in one of four fractured wrists and true negative in two of three nonfractured wrists. MRI was obtained in five wrists (one without a fracture), of which the fracture was recognized in only two. The highest agreement between observers was found in the X-CB 15-degree. Conclusion: From the planar investigated methods, the 15- degree Carpal Box posterior-anterior, longitudinal and transverse views were most accurate in recognizing scaphoid fracture with also the highest agreement between the observers

A highly virulent variant of HIV-1 circulating in the Netherlands.

We discovered a highly virulent variant of subtype-B HIV-1 in the Netherlands. One hundred nine individuals with this variant had a 0.54 to 0.74 log <sub>10</sub> increase (i.e., a ~3.5-fold to 5.5-fold increase) in viral load compared with, and exhibited CD4 cell decline twice as fast as, 6604 individuals with other subtype-B strains. Without treatment, advanced HIV-CD4 cell counts below 350 cells per cubic millimeter, with long-term clinical consequences-is expected to be reached, on average, 9 months after diagnosis for individuals in their thirties with this variant. Age, sex, suspected mode of transmission, and place of birth for the aforementioned 109 individuals were typical for HIV-positive people in the Netherlands, which suggests that the increased virulence is attributable to the viral strain. Genetic sequence analysis suggests that this variant arose in the 1990s from de novo mutation, not recombination, with increased transmissibility and an unfamiliar molecular mechanism of virulence

Human immunodeficiency virus continuum of care in 11 european union countries at the end of 2016 overall and by key population: Have we made progress?

Background. High uptake of antiretroviral treatment (ART) is essential to reduce human immunodeficiency virus (HIV) transmission and related mortality; however, gaps in care exist. We aimed to construct the continuum of HIV care (CoC) in 2016 in 11 European Union (EU) countries, overall and by key population and sex. To estimate progress toward the Joint United Nations Programme on HIV/AIDS (UNAIDS) 90-90-90 target, we compared 2016 to 2013 estimates for the same countries, representing 73% of the population in the region. Methods. A CoC with the following 4 stages was constructed: number of people living with HIV (PLHIV); proportion of PLHIV diagnosed; proportion of those diagnosed who ever initiated ART; and proportion of those ever treated who achieved viral suppression at their last visit. Results. We estimated that 87% of PLHIV were diagnosed; 92% of those diagnosed had ever initiated ART; and 91% of those ever on ART, or 73% of all PLHIV, were virally suppressed. Corresponding figures for men having sex with men were: 86%, 93%, 93%, 74%; for people who inject drugs: 94%, 88%, 85%, 70%; and for heterosexuals: 86%, 92%, 91%, 72%. The proportion suppressed of all PLHIV ranged from 59% to 86% across countries. Conclusions. The EU is close to the 90-90-90 target and achieved the UNAIDS target of 73% of all PLHIV virally suppressed, significant progress since 2013 when 60% of all PLHIV were virally suppressed. Strengthening of testing programs and treatment support, along with prevention interventions, are needed to achieve HIV epidemic control
