  Although under-five (U5) mortality in Uganda has dropped over the past two decades, rates in urban slum neighborhoods remain high. As part of a broader verbal and social autopsy study of U5 deaths, this study explored the perspectives of volunteer community health workers, called Village Health Teams (VHTs), on why children under five in Kampala's informal settlements are still dying despite living in close proximity to nearby health facilities.
 
  This exploratory, qualitative study took place between January and March 2020 in the Rubaga division of Kampala, Uganda. VHTs from the slums of Kawaala and Nankulabye parishes, both located near a large government health center, were interviewed by a trained local interviewer to determine their perceptions of barriers to care-seeking and attribution for U5 childhood deaths. All interviews were audiotaped, transcribed into English, imported into NVivo V 12.0 and thematically analyzed using the Attride-Stirling framework.
 
  20 VHTs were interviewed, yielding two gloces, training, and support.
 This study illustrates VHT perspectives on the complex interactions between health system disincentives and the attitudes and behaviors of families with a sick child, as well as the reinforcing nature of these factors. Findings suggest a need for multi-pronged approaches that sensitize community members, engage community and health system leadership, and hold providers accountable for providing high-quality care. VHTs have enormous potential to foster improvement if given adequate resources, training, and support.Grass pollen allergens are known to be one of the major triggers of hay fever with an increasing number of humans affected by pollen associated health impacts. Climate change characterized by increasing air temperature and more frequent drought periods might affect plant development and pollen characteristics. In this study a one-year (2017) field experiment was conducted in Bavaria, Germany, simulating drought by excluding rain and elevated air temperature by installing a heating system to investigate their effects primarily on the allergenic potential of eight selected cultivars of the two grass species timothy and perennial ryegrass. It could be shown for timothy that especially under drought and heat conditions the allergen content is significantly lower accompanied by a decrease in pollen weight and protein content. In perennial ryegrass the response to drought and heat conditions in terms of allergen content, pollen weight, and protein content was more dependent on the respective cultivar probably due to varying requirements for their growth conditions and tolerance to drought and heat. Results support recommendations which cultivars should be grown preferentially.  https://www.selleckchem.com/  The optimal choice of grass species and respective cultivars under changing climate conditions should be a major key aspect for the public health sector in the future.Eph receptors are the largest group amongst the receptor tyrosine kinases and are divided into two subgroups, A and B, based on ligand binding specificities and sequence conservation. Through ligand-induced and ligand-independent activities, Ephs play central roles in diverse biological processes, including embryo development, regulation of neuronal signaling, immune responses, vasculogenesis, as well as tumor initiation, progression, and metastasis. The Eph extracellular regions (ECDs) are constituted of multiple domains, and previous structural studies of the A class receptors revealed how they interact with ephrin ligands and simultaneously mediate Eph-Eph clustering necessary for biological activity. Specifically, EphA structures highlighted a model, where clustering of ligand-bound receptors relies on two distinct receptor/receptor interfaces. Interestingly, most unliganded A class receptors also form an additional, third interface, between the ligand binding domain (LBD) and the fibronectin III domain (sm of action of the B-class Ephs, and specifically EphB6, which in the future will assist in identifying clinically relevant targets for cancer therapy.With an estimated 440,000 active cases occurring each year, medical device associated infections pose a significant burden on the US healthcare system, costing about $9.8 billion in 2013. Staphylococcus epidermidis is the most common cause of these device-associated infections, which typically involve isolates that are multi-drug resistant and possess multiple virulence factors. S. epidermidis is also frequently a benign contaminant of otherwise sterile blood cultures. Therefore, tests that distinguish pathogenic from non-pathogenic isolates would improve the accuracy of diagnosis and prevent overuse/misuse of antibiotics. Attempts to use multi-locus sequence typing (MLST) with machine learning for this purpose had poor accuracy (~73%). In this study we sought to improve the diagnostic accuracy of predicting pathogenicity by focusing on phenotypic markers (i.e., antibiotic resistance, growth fitness in human plasma, and biofilm forming capacity) and the presence of specific virulence genes (i.e., mecA, ses1, and sdrF). Commensal isolates from healthy individuals (n = 23), blood culture contaminants (n = 21), and pathogenic isolates considered true bacteremia (n = 54) were used. Multiple machine learning approaches were applied to characterize strains as pathogenic vs non-pathogenic. The combination of phenotypic markers and virulence genes improved the diagnostic accuracy to 82.4% (sensitivity 84.9% and specificity 80.9%). Oxacillin resistance was the most important variable followed by growth rate in plasma. This work shows promise for the addition of phenotypic testing in clinical diagnostic applications.
  Many patients at the end of life require analgesia to relieve pain. Additionally, up to 1/5 of patients in the UK receive sedation for refractory symptoms at the end of life. The use of sedation in end-of-life care (EOLC) remains controversial. While gradual sedation to alleviate intractable suffering is generally accepted, there is more opposition towards deliberate and rapid sedation to unconsciousness (so-called "terminal anaesthesia", TA). However, the general public's views about sedation in EOLC are not known. We sought to investigate the general public's views to inform policy and practice in the UK.
 
  We performed two anonymous online surveys of members of the UK public, sampled to be representative for key demographic characteristics (n = 509). Participants were given a scenario of a hypothetical terminally ill patient with one week of life left. We sought views on the acceptability of providing titrated analgesia, gradual sedation, terminal anaesthesia, and euthanasia. We asked participants about the intentions of doctors, what risks of sedation would be acceptable, and the equivalence of terminal anaesthesia and euthanasia.
