Quantitative analysis of the implementation of the bedside paediatric early warning system (B-PEWS) in a resource-limited setting. The B-PEWS serves to pre-emptively identify hospitalised children who are at risk for cardiopulmonary arrest and subsequently to provide critical care in time.

We performed a retrospective review through the medical data records of patients after discharge from the paediatric ward of a philanthropic hospital in Brazil. Nurses' performance using the system was measured with various parameters.

A total of 499 patients were included, and a total of 8024scores were checked. During the 21-week research period, the implementation rate increased significantly from 66.5% (SD 26.0) in Period 1 to 93.1% (SD 16.6) in Period 2. The number of scores that resulted in a correct total score went from 7.5% in Period 1 to 32.2% in Period 2, p < 0.001. There was an improvement in the correct choice of age group between the two periods (from 32.2% to 53.4%). There was no difference in the mean admission time of patients in the two periods in the first period 4.8days (SD 2.9) and in the second period 4.8days (SD 4.1).

It is possible to implement a PEWS in resource-limited settings while achieving high implementation rates. However, this is a time- and energy-consuming process. Having an active and involved team that is responsible for implementation is key for a successful implementation. Factors that likely hindered implementation were a large change in workflow for the nursing staff, non-native speakers as main investigators.

First described in dogs and Tasmanian devils, transmissible cancers were later discovered in some marine bivalves affected by a leukaemia-like disease. In Mytilus mussels, two lineages of bivalve transmissible neoplasia (BTN) have been described to date (MtrBTN1 and MtrBTN2), both of which emerged in a Mytilus trossulus founder individual. Here, we performed extensive screening of genetic chimerism, a hallmark of transmissible cancer, by genotyping 106 single nucleotide polymorphisms of 5,907 European Mytilus mussels. Genetic analysis allowed us to simultaneously obtain the genotype of hosts - Mytilus edulis, M. galloprovincialis or hybrids - and the genotype of tumours of heavily infected individuals. In addition, a subset of 222 individuals were systematically genotyped and analysed by histology to screen for possible nontransmissible cancers. We detected MtrBTN2 at low prevalence in M. edulis, and also in M. galloprovincialis and hybrids although at a much lower prevalence. No MtrBTN1 or new BTN were found, but eight individuals with nontransmissible neoplasia were observed at a single polluted site on the same sampling date. We observed a diversity of MtrBTN2 genotypes that appeared more introgressed or more ancestral than MtrBTN1 and reference healthy M. trossulus individuals. The observed polymorphism is probably due to somatic null alleles caused by structural variations or point mutations in primer-binding sites leading to enhanced detection of the host alleles. Despite low prevalence, two sublineages divergent by 10% fixed somatic null alleles and one nonsynonymous mtCOI (mitochondrial cytochrome oxidase I) substitution are cospreading in the same geographical area, suggesting a complex diversification of MtrBTN2 since its emergence and host species shift.Psoriasis and psoriatic arthritis (PsA) are interrelated inflammatory diseases. Psoriasis usually precedes PsA onset and represents a well-established risk factor for PsA development. Bone erosion is a hallmark of PsA, and the contribution of cutaneous psoriatic inflammation in this process has been demonstrated. However, little is still known on the pathogenetic mechanisms that link psoriatic skin to joint damage. Clinical features of psoriatic disease, including specific body site involvement, seem to be important risk predictors of PsA. The aim of this pilot research study was to investigate if psoriatic cutaneous inflammation, affecting these anatomical predictive sites for PsA, could be linked to osteoclast differentiation and activity. Our results showed that psoriasis skin localizations were positively related to the osteoclastogenic profile in psoriatic patients. These results provide new insights into the fascinating skin-joint axis concept.

Diaphragmatic dysfunction is common after cardiothoracic surgery, but few studies report its incidence and consequences after lung transplantation. We aimed to estimate the incidence of diaphragmatic dysfunction using ultrasound in lung transplant patients up to 3months postoperatively and evaluated the impact on clinical outcomes.

This was a single-center prospective observational cohort study of 27 lung transplant recipients using diaphragmatic ultrasound preoperatively, at 1day, 1week, 1month, and 3months postoperatively. Diaphragmatic dysfunction was defined as excursion<10mm in men and<9mm in women during quiet breathing. Clinical outcomes measured included duration of mechanical ventilation, length of stay (LOS) in Intensive Care (ICU), and hospital LOS.

Sixty-two percentage of recipients experienced new, postoperative diaphragmatic dysfunction, but the prevalence fell to 22% at 3months. No differences in clinical outcomes were found between those with diaphragmatic dysfunction compared to those without. Patients who experienced diaphragmatic dysfunction at 1day postoperatively were younger and had a lower BMI than those who did not.

Diaphragmatic dysfunction is common after lung transplant, improves significantly within 3months, and did not impact negatively on duration of mechanical ventilation, LOS in ICU or hospital, or discharge destination.

Here, we employ genomic data to gain insights into key demographic processes that might help to explain the extraordinarily successful invasion of the Western Mediterranean region by the North American boatman Trichocorixa verticalis (Hemiptera Corixidae). Our analyses revealed the genetic distinctiveness of populations from the main areas comprising the invasive range and coalescent-based simulations supported that they originated from independent introductions events probably involving different source populations. Testing of alternative demographic models indicated that all populations experienced a strong bottleneck followed by a recent and instantaneous demographic expansion that restored a large portion (>30%) of their ancestral effective population sizes shortly after introductions took place ( less then 60 years ago). Considerable genetic admixture of some populations suggest that hypothetical barriers to dispersal (i.e., land and sea water) are permeable to gene flow and/or that they originated from introductions involving multiple lineages. This study demonstrates the repeated arrival of propagules with different origins and short time lags between arrival and establishment, emphasizing the extraordinary capacity of the species to recover from founder effects and genetically admix in invaded areas. This can explain the demonstrated capacity of this aquatic insect to spread and outcompete native species once it colonizes new suitable regions. Future genomic analyses of native range populations could help to infer the genetic makeup of introduced populations and track invasion routes.Under-representation of people with dementia in clinical research remains a significant obstacle to develop evidence-based practice guidelines and recommendation for dementia care and slows down the development of disease-modifying pharmacological interventions. This is partly due to the ethical challenges and complexities of recruiting people with dementia for clinical trials. The traditional approach adopted by research ethics committees and regulatory bodies has been to protect people with dementia as a vulnerable population from harms of participating in research. There are concerns that this approach is unduly rigid, precludes the conduct of necessary research, and has exclusionary, paternalistic and discriminatory ramifications. As such, there are increasing calls to shift to a new hybrid facilitative/protective approach. This paper identifies 4 strategies to operationalise the facilitative/protective approach in the context of dementia research. These are (i) embedding dementia research in clinical care; (ii) increasing the recruitment of people at preclinical stages of dementia; (iii) streamlined proxy consent procedures; and (iv) advance research consent. I note that all 4 strategies hold the promise of facilitating the recruitment of people with dementia in clinical research. Nonetheless, they give rise to a diverse range of new ethical concerns and issues. This necessitates further scholarly work to explore possible ways to address the ethical concerns and issues arisen by the uptake of protective/facilitative approach. In particular, further research is necessary to clarify, to what extent, the said strategies ameliorate or increase the vulnerability of people with dementia.White kidney transplant candidates have the highest pre-transplant mortality rate compared to other ethnicities. The reason for a higher mortality rate is not well understood. Estimated post transplant survival (EPTS) score has been used to predict patient survival after transplant and may be associated with pre-transplant survival. First-time kidney transplant candidates listed between 2015-2018 were identified from the OPTN database. Individuals listed for multiple organs, at multiple centers, and age less then 18 years were excluded. We examined the impact of ethnicity on waitlist mortality and delisting. A total of 114,806 candidates were included. The study population was categorized into 4 groups which were 43% white, 28% Black, 19.2% Hispanic and 9.8% "other ethnicities". At 5.2 years, the cumulative incidences of death and delist were 32%, 31%, 29% and 26%, respectively. Compared to whites, aSHR for death and delist among Black, Hispanics and "other ethnicities" were 0.92 (95% CI 0.89-0.95), 0.89 (95% CI 0.85-0.91) and 0.76 (95% CI 0.72-0.80) after adjustment by EPTS along with other factors, respectively. AS1842856 in vitro After adjusting for EPTS score along with additional confounding factors and functional status at initial listing, white ethnicity was independently associated with an increased risk for death and delist.
