Hypervirulent Klebsiella pneumoniae Endogenous Endophthalmitis—A Global Emerging Disease

2021

The review aims to document the new emerging hypervirulent Klebsiella pneumoniae (Kp) endogenous endophthalmitis (EKE) in terms of incidence, microbiological characterization of the pathogenic agent, associated risk factors, management, and outcomes. Hypervirulent (hv) strains of KP (hvKp) induce invasive liver abscesses (LA) with specific clinical features. Up to 80–90% of cases have hepatic liver abscess as a primary focus of infection, followed by renal or lung hvKp infections. However, the incidence of EKE in patients with KPLA varied between 3.4% (19) and 12.6% (13), with a total of 95 cases of endophthalmitis in 1455 cases of KPLA (6.5%). Severe visual loss was encountered in 75% of c…

Monitoring of ticks and tick-borne pathogens through a nationwide research station network in Finland.

2020

In 2015 a long-term, nationwide tick and tick-borne pathogen (TBP) monitoring project was started by the Finnish Tick Project and the Finnish Research Station network (RESTAT), with the goal of producing temporally and geographically extensive data regarding exophilic ticks in Finland. In the current study, we present results from the first four years of this collaboration. Ticks were collected by cloth dragging from 11 research stations across Finland in May September 2015-2018 (2012-2018 in Seili). Collected ticks were screened for twelve different pathogens by qPCR: Borrelia afzelii, Borrelia garinii, Borrelia valaisiana, Borrelia burgdorferi sensu stricto, Borrelia miyamotoi, Babesia sp…

Methods for assessing the severity of perinatal asphyxia and early prognostic tools in neonates with hypoxic-ischemic encephalopathy treated with the…

2020

Despite the progress in perinatal care, perinatal asphyxia (PA) remains a significant problem in neonatology. The development of therapeutic hypothermia (TH) has improved the prognosis, but it still remains uncertain in hypoxic neonates. The evaluation of the severity of ischemia/hypoxia after birth is crucial to the choice of treatment, and with accurate long-term prognosis, appropriate further patient care can be planned. This article presents various methods for the preliminary assessment of brain damage and prognosis in newborns with PA treated with TH. The importance of assessing the neurological condition and the usefulness of laboratory and electrophysiological testing and imaging ar…

New Mediterranean Biodiversity Records (November 2020)

2019

This article includes 23 new records of alien and cryptogenic species in the Mediterranean Sea, belonging to 4 Phyla (Chordata, Echinodermata, Arthropoda and Mollusca), distributed from the Alboran to the Levantine Sea. Records are reported from eight countries listed from West to East as follows: Algeria : new records of the Atlantic blue crab Callinectes sapidus ; Spain : further spread and establishment of the sea slug Lamprohaminoea ovalis in continental shores; Tunisia : first record of the Atlantic Blue Crab Callinectes sapidus in the Gulf of Gabes; Italy : a new occurrence of the pufferfish Lagocephalus sceleratus in Northern Ionian waters; first record of Cephalopholis taeniops in t…

Background Little is known about the modulation of cortical excitability in the prefrontal cortex during fear processing in humans. Here, we aimed to transiently modulate and test the cortical excitability during fear processing using transcranial magnetic stimulation (TMS) and brain oscillations in theta and alpha frequency bands with electroencephalography (EEG). Methods We conducted two separate experiments (no-TMS and TMS). In the no-TMS experiment, EEG recordings were performed during the instructed fear paradigm in which a visual cue (CS+) was paired with an aversive unconditioned stimulus (electric shock), while the other visual cue was unpaired (CS-). In the TMS experiment, in addit…

During speech perception listeners rely on multimodal input and make use of both auditory and visual information. When presented with speech, for example syllables, the differences in brain responses to distinct stimuli are not, however, caused merely by the acoustic or visual features of the stimuli. The congruency of the auditory and visual information and the familiarity of a syllable, that is, whether it appears in the listener’s native language or not, also modulates brain responses. We investigated how the congruency and familiarity of the presented stimuli affect brain responses to audio-visual (AV) speech in 12 adult Finnish native speakers and 12 adult Chinese native speakers. They…

The effects of 8-weeks Mindfulness-Based Stress Reduction program on cognitive control: an EEG study

2019

Objectives: Mindfulness practice can enhance different aspects of attentional functions, such as the ability to sustain the attentional focus over time. However, it is still unclear whether this practice might indeed impact higher cognitive functions, such as control mechanisms that allow the appropriate and flexible allocation of attentional resources. In this longitudinal study, changes associated with a mindfulness-based stress reduction (MBSR) program were investigated, with a focus on proactive and reactive cognitive control mechanisms, namely, the ability to maintain task-relevant information and to prepare in advance the response, and the ability to promptly adjust overlearned behavi…

Predicting habitat suitability for Ixodes ricinus and Ixodes persulcatus ticks in Finland

2022

AbstractBackgroundTicks are responsible for transmitting several notable pathogens worldwide. Finland lies in a zone where two human-biting tick species co-occur:IxodesricinusandIxodespersulcatus. Tick densities have increased in boreal regions worldwide during past decades, and tick-borne pathogens have been identified as one of the major threats to public health in the face of climate change.MethodsWe used species distribution modelling techniques to predict the distributions ofI.ricinusandI.persulcatus,using aggregated historical data from 2014 to 2020 and new tick occurrence data from 2021. By aiming to fill the gaps in tick occurrence data, we created a new sampling strategy across Fin…

Cellular mechanisms of IL-17-induced blood-brain barrier disruption.

2009

Recently T-helper 17 (Th17) cells were demonstrated to disrupt the blood-brain barrier (BBB) by the action of IL-17A. The aim of the present study was to examine the mechanisms that underlie IL-17A-induced BBB breakdown. Barrier integrity was analyzed in the murine brain endothelial cell line bEnd.3 by measuring the electrical resistance values using electrical call impedance sensing technology. Furthermore, in-cell Western blots, fluorescence imaging, and monocyte adhesion and transendothelial migration assays were performed. Experimental autoimmune encephalomyelitis (EAE) was induced in C57BL/6 mice. IL-17A induced NADPH oxidase- or xanthine oxidase-dependent reactive oxygen species (ROS)…
