Comparison of BD MAX GBS and GenomEra GBS assays for rapid intrapartum PCR detection of vaginal carriage of group B streptococci

Plos.org 

by Trine Andreasen, Jens Kjølseth Møller, Mohammed Rohi Khalil

Objective

To compare the diagnostic performance of BD MAX and GenomEra PCR assays for a rapid PCR detection of vaginal carriage of group B streptococci at delivery.

Methods

This is a retrospective laboratory analysis of vaginal swab samples taken intrapartum from a randomly selected cohort of pregnant women giving birth at a single childbirth and maternity unit.

Results

Ninety-one culture-positive and 279 culture-negative... Читать дальше...

Effects of the amount of practice and time interval between practice sessions on the retention of internal models

Plos.org 

by Chiharu Yamada, Yoshihiro Itaguchi, Kazuyoshi Fukuzawa

The amount of practice and time interval between practice sessions are important factors that influence motor learning efficiency. Here, we aimed to reveal the relationship between the retention and consolidation of a new internal model, and the amount of practice and time interval between practice sessions. We employed a visuomotor rotation tracking task to test the hypotheses that (1) a new internal model consolidates owing to extensive... Читать дальше...



The acute effects of whole blood donation on cardiorespiratory and haematological factors in exercise: A systematic review

Plos.org 

by Diane Maria Johnson, Justin Roberts, Dan Gordon

Background

This systematic review aimed to collect the relevant historical and current literature to produce an informed analysis of the acute effects on cardiorespiratory and haematological factors following whole blood donation (~ 470 ml) during exercise. Testing the hypothesises that blood donation produces either no changes (Null) or produces significant changes (alternate) in haematology, V.O2, heart rate, exercising power and time.

In vivo three-dimensional kinematics of the cervical spine during maximal active head rotation

Plos.org 

by Jian Kang, Guangru Chen, Xu Zhai, Xijing He

Objective

The aim of this study was to measure the movement of the cervical spine in healthy volunteers and patients with cervical spondylosis (CS) and describe the actual motion of the cervical spine using a three-dimensional (3D) CT reconstruction method. The results can enrich current biomechanical data of cervical spine and help to find the differences between the noted two groups.

Materials and methods

20 healthy volunteers underwent... Читать дальше...

Policy makers’ perceptions of the high burden of heart disease in rural Australia: Implications for the implementation of evidence-based rural health policy

Plos.org 

by Laura Alston, Melanie Nichols, Steven Allender

Background

Rural Australian populations experience an increased burden of ischaemic heart disease (IHD) compared to their metropolitan counterparts, similar to other developed countries, globally. Policy and other efforts need to address and acknowledge these differences in order to reduce inequalities in health burden. This paper examines rural health policy makers’ perceptions and use of evidence in efforts to reduce the burden of IHD in rural areas. Читать дальше...

Detecting spatio-temporal hotspots of scarlet fever in Taiwan with spatio-temporal Gi* statistic

Plos.org 

by Jia-Hong Tang, Tzu-Jung Tseng, Ta-Chien Chan

A resurgence of scarlet fever has caused many pediatric infections in East Asia and the United Kingdom. Although scarlet fever in Taiwan has not been a notifiable infectious disease since 2007, the comprehensive national health insurance data can still track its trend. Here, we used data from the open data portal of the Taiwan Centers for Disease Control. The scarlet fever trend was measured by outpatient and hospitalization rates from 2009 to 2017.

Investigation of Pseudomonas aeruginosa strain PcyII-10 variants resisting infection by N4-like phage Ab09 in search for genes involved in phage adsorption

Plos.org 

by Libera Latino, Cédric Midoux, Gilles Vergnaud, Christine Pourcel

Bacteria and their bacteriophages coexist and coevolve for the benefit of both in a mutualistic association. Multiple mechanisms are used by bacteria to resist phages in a trade-off between survival and maintenance of fitness. In vitro studies allow inquiring into the fate of virus and host in different conditions aimed at mimicking natural environment. We analyse here the mutations emerging in a clinical Pseudomonas aeruginosa strain in response to infection by Ab09... Читать дальше...

The reflective component of the Mellow Bumps parenting intervention: Implementation, engagement and mechanisms of change

Plos.org 

by Katie Buston, Rosaleen O’Brien, Daniel Wight, Marion Henderson

Understanding why parenting programmes work or do not work, and for whom, is crucial for development of more effective parenting interventions. In this paper we focus on a specific component of Mellow Bumps: reflection on one’s own childhood/past/life. We explore how this component was implemented, how participants engaged with it, the facilitating and constraining factors shaping this, whether and how it appeared to work, or not, and for whom.

Glyphosate, but not its metabolite AMPA, alters the honeybee gut microbiota

Plos.org 

by Nicolas Blot, Loïs Veillat, Régis Rouzé, Hélène Delatte

The honeybee (Apis mellifera) has to cope with multiple environmental stressors, especially pesticides. Among those, the herbicide glyphosate and its main metabolite, the aminomethylphosphonic acid (AMPA), are among the most abundant and ubiquitous contaminant in the environment. Through the foraging and storing of contaminated resources, honeybees are exposed to these xenobiotics. As ingested glyphosate and AMPA are directly in contact with the honeybee gut microbiota...

High-resolution directed human connectomes and the Consensus Connectome Dynamics

Plos.org 

by Balázs Szalkai, Csaba Kerepesi, Bálint Varga, Vince Grolmusz

Here we show a method of directing the edges of the connectomes, prepared from HARDI datasets from the human brain. Before the present work, no high-definition directed braingraphs were published, because the tractography methods in use are not capable of assigning directions to the neural tracts discovered. Previous work on the functional connectomes applied low-resolution functional MRI-detected statistical causality for the... Читать дальше...
