5 nm.Giardia intestinalis is a parasitic protozoan that inhabits its vertebrate hosts' upper small intestine and is the most common cause of waterborne diarrhoea worldwide. Giardia trophozoites present few organelles, and among them, they possess peripheral vesicles (PVs), which are considered an endosomal-lysosomal system. All experimental procedures carried out until now indicate that Giardia ingests macromolecules by fluid-phase and receptor-mediated endocytic pathways. Still, there is no description concerning the interaction and ingestion of large materials. Here, we tested Giardia's capacity to interact with large particles; once, in vivo, it inhabits an environment with a microbiota. We tested protozoan interaction with yeasts, bacteria, latex beads, ferritin and albumin, in different times of interaction and used several microscopy techniques (light microscopy, scanning electron microscopy and transmission electron microscopy) to follow their fate. Giardia interacted with all of the materials we tested. Projections of the plasma membrane similar to pseudopods were seen. As albumin, small markers were found in the PVs while the larger materials were not seen there. Large vacuoles containing large latex beads were detected intracellularly. Thus, we observed that (1) Giardia interacts with large materials; (2) Giardia can display an amoeboid shape and exhibit membrane projections when in contact with microorganisms and large inorganic materials; (3) the region of the exit of the ventral flagella is very active when in contact with large materials, although all cell surface also present activity in the interactions; (4) intracellular vacuoles, which are not the PVs, present ingested large beads.

To evaluate the methodological and reporting characteristics of search methods of systematic reviews (SRs) using the Preferred Reporting of Systematic Reviews and Meta-Analyses (PRISMA) checklist and the Risk Of Bias In Systematic reviews (ROBIS) tool.

A sample of 505 SRs published in 2016 was taken from KSR Evidence, a database of SRs, and analyzed to assess compliance with Information sources and Search of the PRISMA checklist. Domain 2 (D2) (Identification and Selection of Studies) of the ROBIS tool was used to judge the risk of bias in search methods.

Regarding Information sources and Search of PRISMA, twenty percent of SRs which claimed to be PRISMA-compliant in their methods, were compliant; twenty-four percent of SRs published in journals that require PRISMA reporting were compliant; nineteen percent in total were found to be compliant. Twenty-eight percent of SRs were judged to be at a low risk of bias in D2 and so searched widely with an effective strategy and, finally, ten percent were both compliant with the reporting of Information sources and with Search of PRISMA and were judged to be at a low risk of bias in D2.

Ninety percent of SRs are failing to report search methods adequately and to conduct comprehensive searches using a wide range of resources. Editors of journals and peer reviewers need to ensure that they understand the requirements of PRISMA and that compliance is adhered to. Additionally, the comprehensiveness of search methods for SRs needs to be given more critical consideration.

Depending on the health system context and the demands of relevant stakeholders in countries, the need, organizational structure, and prerequisites for enabling capacity building and development in health technology assessment (HTA) will vary. Core competencies are instrumental in this and include essential knowledge, skills, and attitudes (KSAs). They provide building blocks for delivering high-quality and effective practices of HTA. We aimed to systematically explore and develop an overview of the core competencies necessary for HTA.

This study was conducted during 2016-19 using different methods in a structured manner. We drew concepts of KSAs from various literature sources, surveyed universities and HTA professionals, and conducted expert workshops to arrive at a common understanding of the required competencies.

The terminology for KSAs defining competencies in HTA programs has been clarified. In addition, a list of competencies offered through different educational and training programs has been ic needs of the HTA community will be covered.

To investigate associations between healthcare-associated Clostridioides difficile infection and patient demographics at an urban safety-net hospital and compare findings with national surveillance statistics.

Study participants were selected using a case-control design using medical records collected between August 2014 and May 2018 at Hahnemann University Hospital in Philadelphia. Controls were frequency matched to cases by age and length of stay. Final sample included 170 cases and 324 controls. Neighborhood-level factors were measured using American Community Survey data. Multilevel models were used to examine infection by census tract, deprivation index, race/ethnicity, insurance type, referral location, antibiotic use, and proton-pump inhibitor use.

Patients on Medicare compared to private insurance had 2.04 times (95% CI, 1.31-3.20) the odds of infection after adjusting for all covariables. Prior antibiotic use (2.70; 95% CI, 1.64-4.46) was also associated with infection, but race or ethnicity anmore, a greater proportion of hospital cases were aged less then 65 years than expected based on national data. National surveillance statistics on CDI may not be transportable to safety-net hospitals, which often disproportionately serve low-income, nonwhite patients.Surgical site infection (SSI) prevention requires multiple interventions packaged into "bundles." The implementation of all bundle elements is key to the bundle's efficacy. A human-factors engineering approach can be used to identify key barriers and facilitators to implementing elements and develop recommendations for bundle implementation within the clinical work system.
