Forecasting SARS-CoV-2 epidemic dynamic in Poland with the pDyn agent-based model.

We employ pDyn (derived from "pandemics dynamics"), an agent-based epidemiological model, to forecast the fourth wave of the SARS-CoV-2 epidemic, primarily driven by the Delta variant, in Polish society. The model captures spatiotemporal dynamics of the epidemic spread, predicting disease-related states based on pathogen properties and behavioral factors. We assess pDyn's validity, encompassing pathogen variant succession, immunization level, and the proportion of vaccinated among confirmed cases.

Infiltration and Extravasation Risk with Midline Catheters: A Narrative Literature Review.

Midline catheters have recently gained popularity in clinical use, with a common reason being the reduction of central venous catheter use and central line-associated bloodstream infections. At the same time, the number of nononcology vesicant medications has increased, and midline catheters are frequently being used for infusions of vesicant medications. The Infusion Nurses Society (INS) Vesicant Task Force identified midline catheter use as a possible risk factor for extravasation and concluded that a thorough literature review was necessary.

Development of an Evidence-Based List of Non-Antineoplastic Vesicants: 2024 Update.

Infiltration of a vesicant, called extravasation, can result in severe patient injuries. Recognition of vesicants and their relative risk of injury is essential to extravasation prevention, early recognition, and appropriate treatment. In this article, the Vesicant Task Force (VTF) updates the previously published Infusion Nurses Society (INS) vesicant list from 2017.

Fitness Differences Between Listeria monocytogenes Serotypes 1/2a, 4b, and 4bv-1 in Competition for Growth on Lettuce Leaf Sections.

Listeria monocytogenes is a foodborne pathogen that lives in nature as a saprophyte. Two of the three most common serotypes that cause foodborne listeriosis are 1/2a and 4b. Within serotype 4b, there is a variant called 4bv-1.

Data came from registries maintained by the Polish Transplant Coordinating Center Poltransplant and consisted of the national waiting list, deceased donor registry, transplant registry, and the live donor registry. Poltransplant is the Competent Authority in Organs, with tasks related to preparing assessments, analyses, information, and reports in transplantation medicine and publishing and disseminating these results in the country and abroad.

Growth assessment of Salmonella enterica multi-serovar populations in poultry rinsates with commonly used enrichment and plating media.

Isolation of Salmonella from enrichment cultures of food or environmental samples is a complicated process. Numerous factors including fitness in various selective enrichment media, relative starting concentrations in pre-enrichment, and competition among multi-serovar populations and associated natural microflora, come together to determine which serovars are identified from a given sample. A recently developed approach for assessing the relative abundance (RA) of multi-serovar Salmonella populations (CRISPR-SeroSeq or Deep Serotyping, DST) is providing new insight into how these factors impact the serovars observed, especially when different selective enrichment methods are used to identify Salmonella from a primary enrichment sample.

Comparison of Phenotype Nutritional Profiles and Phosphate Metabolism Genes in Four Serovars of from Water Sources.

The surveillance of foods for is hindered by bias in common enrichment media where serovars implicated in human illness are outgrown by less virulent serovars. We examined four serovars, two common in human illness (Enteritidis and Typhimurium) and two that often dominate enrichments (Give and Kentucky), for factors that might influence culture bias. The four serovars had similar growth kinetics in Tryptic Soy Broth and Buffered Peptone Water.

International Consensus Recommendation Guidelines for Subcutaneous Infusions of Hydration and Medication in Adults: An e-Delphi Consensus Study.

Infusion of fluids and medications is traditionally performed intravenously. However, venous depletion in patients has led to the quest for vessel health preservation. A safe, effective, acceptable, and efficient alternative is the subcutaneous route.

Horizontal Gene Transfer and Loss of Serotype-Specific Genes in Listeria monocytogenes Can Lead to Incorrect Serotype Designations with a Commonly-Employed Molecular Serotyping Scheme.

Listeria monocytogenes is a Gram-positive, facultative intracellular foodborne pathogen capable of causing severe, invasive illness (listeriosis). Three serotypes, 1/2a, 1/2b, and 4b, are leading contributors to human listeriosis, with 4b including the major hypervirulent clones. The multiplex PCR scheme developed by Doumith and collaborators employs primers targeting specific lineages (e.

Toward an Electronic Tongue Based on Surfactant-Stabilized Chemosensory Microparticles with a Dual Detection Mode.

We propose a novel type of electronic tongue based on four types of monodispersed chemosensory microparticles (MPs) with a lipophilic core stabilized by a nonionic poloxamer surfactant. The lipophilic core composition was designed to achieve cross-sensitivity toward various ions and to enable spectrophotometric and/or spectrofluorimetric detection. Thus, generic anion-selective MPs, generic cation-selective MPs, as well as two types of metalloporphyrin-based MPs were fabricated and their morphology was characterized.

Prevalence and Clonal Diversity of over 1,200 Listeria monocytogenes Isolates Collected from Public Access Waters near Produce Production Areas on the Central California Coast during 2011 to 2016.

A 5-year survey of public access surface waters in an agricultural region of the Central California Coast was done to assess the prevalence of the foodborne pathogen Listeria monocytogenes. In nature, L. monocytogenes lives as a saprophyte in soil and water, which are reservoirs for contamination of preharvest produce.

Prevalence and serovar diversity of Salmonella enterica were measured during a 5-year survey of surface waters in a 500-mi agricultural region of the Central California Coast. Rivers, streams, lakes, and ponds were sampled bimonthly resulting in 2,979 samples. Overall prevalence was 56.

Antimicrobial Resistance and Antimicrobial Stewardship in Home Healthcare.

Antimicrobial resistance, the ability of microbes to become resistant to known antimicrobial medications, is a growing and serious global health concern. There are growing numbers of publications about efforts to educate nurses about antimicrobial resistance, and efforts to involve nurses in antimicrobial stewardship in acute and long-term care settings; however, this has not been the case in home care. Home care organizations are required to address infection control and surveillance, including patient, family, and staff education.
