Abstract
OBJECTIVE The objective of this scoping review is to explore and map the scientific evidence on organizational factors related to safe food handling by food service workers to prevent foodborne disease. INTRODUCTION According to the World Health Organization, more than 600 million people become ill each year due to foodborne diseases. Improper food handling is one of the main causes of such diseases. Despite the growing literature on safe food handling, many studies focus on assessing and discussing cognitive variables, such as food safety knowledge. This indicates a need to study this topic from a new perspective, for example, through its organizational factors. INCLUSION CRITERIA The review will include quantitative and qualitative studies on food handlers working in food services. Food handlers involved in industrial processing, planting, harvesting, and working on the street (street food) or in the home will be excluded. METHODS This review will use the JBI methodology for scoping reviews to identify published and unpublished studies in all languages, with no time limit. The following databases will be searched: Scopus, CINAHL, Embase, Web of Science, MEDLINE, PsycINFO, and Food Science and Technology Abstracts. A structured search for gray literature will also be conducted. Titles, abstracts, and full texts of articles will be screened by 2 reviewers for inclusion, with discrepancies resolved by a third reviewer. Data will be extracted using a standardized form. The results will be summarized in tabular or graphical format, accompanied by a narrative summary. KEY DETAILS OF THIS REVIEW PROJECT ARE AVAILABLE IN OPEN SCIENCE FRAMEWORK https://osf.io/hxfe4.

[PMID: 35408686 PMCID: PMC9000774 DOI: 10.3390/molecules27072288] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/15/2022] [Revised: 03/22/2022] [Accepted: 03/22/2022] [Indexed: 11/16/2022] Open
Abstract
Nanomaterial technology has attracted much attention because of its antibacterial and drug delivery properties, among other applications. Metal-organic frameworks (MOFs) have advantages, such as their pore structure, large specific surface area, open metal sites, and chemical stability, over other nanomaterials, enabling better drug encapsulation and adsorption. In two examples, we used the common pathogenic bacterium Staphylococcus aureus and highly infectious influenza A virus. A novel complex MIL-101(Fe)-T705 was formed by synthesizing MOF material MIL-101(Fe) with the drug favipiravir (T-705), and a hot solvent synthesis method was applied to investigate the in vitro antibacterial and antiviral activities. The results showed that MIL-101(Fe)-T705 combined the advantages of nanomaterials and drugs and could inhibit the growth of Staphylococcus aureus at a concentration of 0.0032 g/mL. Regarding the inhibition of influenza A virus, MIL-101(Fe)-T705 showed good biosafety at 12, 24, 48, and 72 h in addition to a good antiviral effect at concentrations of 0.1, 0.2, 0.4, 0.8, 1.6, and 3 μg/mL, which were higher than MIL-101(Fe) and T-705.

Vet Parasitol Reg Stud Reports 2022; 28:100677. [PMID: 35115117 DOI: 10.1016/j.vprsr.2021.100677] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/09/2021] [Revised: 11/29/2021] [Accepted: 12/02/2021] [Indexed: 12/13/2022]
Abstract
The epidemiology of Cryptosporidium spp. in Latvia was investigated by testing fecal samples from 926 animals aged from one day to 24 years for the presence of Cryptosporidium spp. oocysts. The samples were collected from 87 cattle farms and from four slaughterhouses, and analyzed by conventional and fluorescent microscopy, followed by Cryptosporidium species and C. parvum subtype differentiation. Moreover, using a questionnaire, we surveyed factors that could be relevant as risk factors of Cryptosporidium spp. infection on the farms. Cryptosporidium spp. were shed by 33.8% of the investigated cattle and at least one shedding animal was found on 77.8% of the farms. In the present study, all four Cryptosporidium species reported to commonly infect cattle and two additional Cryptosporidium species (C. scrofarum and C. ubiquitum) were identified. In addition, mix infections of C. parvum/C. bovis, C. bovis/C. ryanae, C. parvum/C. ryanae, C. parvum/C. andersoni and C. bovis/C. andersoni were observed. C. parvum and C. bovis was mostly prevalent in young animals (0-3 months old) and in addition, diarrhea associated with C. parvum infection was observed only in very young animals. Cryptosporidium andersoni and C. ryanae in age group 0-3 months was observed in low prevalence, while a higher proportion of animals with diarrhea associated with C. andersoni infection was observed in very young animals and with C. ryanae in animals age group 4-24 months. Eight previously described C. parvum subtypes were observed. The majority of the subtypes were in the IIa subtype family, while one subtype was identified from the IId subtype family. The most common subtype was IIaA15G2R1, which was found in 34.2% of the C. parvum successfully subtyped samples. The probability of Cryptosporidium spp. associated diarrhea in cattle decreased significantly with the age of the animals and a prolonged period during which calves were fed with milk.

Abstract
National burden of foodborne disease (FBD) studies are essential to establish food safety as a public health priority, rank diseases, and inform interventions. In recent years, various countries have taken steps to implement them. Despite progress, the current burden of disease landscape remains scattered, and researchers struggle to translate findings to input for policy. We describe the current knowledge base on burden of FBDs, highlight examples of well-established studies, and how results have been used for decision-making. We discuss challenges in estimating burden of FBD in low-resource settings, and the experience and opportunities deriving from a large-scale research project in these settings. Lastly, we highlight the role of international organizations and initiatives in supporting countries to develop capacity and conduct studies.

Abstract
ABSTRACT The aim of this study was to develop a chitosan biofilm against Salmonella enteritidis, for the conservation of fertile and table eggs. Two experiments were performed. Experiment 1: 400 specific pathogen-free table eggs were divided in a completely randomized design into four treatments, five replicates and each replicate with 20 table eggs. Experimental groups were assigned to control and 1, 5 and 10% chitosan treatment. The eggs were immersed in the chitosan solution. They were then exposed to Salmonella enteritidis and stored for 1, 24, 96 and 168h at 4ºC. The eggs were then washed with 10mL of physiological saline solution. Experiment 2: 80 specific pathogen-free fertile eggs were tested, the assays were assigned to control and 1, 5 and 10% chitosan treatment. Each treatment had 20 fertile eggs. The eggs were immersed in the chitosan solution. They were individually weighed and incubated. Egg weight, humidity loss, and hatchability (weight and length of newly hatched chicks) characteristics were assessed. In Experiment 1, comparison between treatments showed differences (P< 0.05) in the total recovered of Salmonella enteritidis on eggshell, with the lower values in 5 y 10% chitosan treatment at 96 y 168h respectively. In Experiment 2, chitosan did not show any effect on the egg weight and chick weight, where the average was 57.44 and 38.23g respectively. The humidity loss and chick length showed differences (P< 0.05), with the lower values in 5 y 10% chitosan treatment. The antibacterial activity of chitosan biofilm provide a practical tool against Salmonella enteritidis in fertile and table eggs because the chitosan did not affect egg weight and chick weight, relevant parameters in the poultry industry.

Abstract
This paper reviews the current knowledge and understanding of Cryptosporidium spp. and Giardia spp. in humans, animals and the environment in 10 countries in the eastern part of Europe: Bosnia and Herzegovina, Croatia, Czech Republic, Estonia, Hungary, Latvia, Poland, Romania, Serbia and Slovenia. Methods: Published scientific papers and conference proceedings from the international and local literature, official national health service reports, national databases and doctoral theses in local languages were reviewed to provide an extensive overview on the epidemiology, diagnostics and research on these pathogens, as well as analyse knowledge gaps and areas for further research. Results: Cryptosporidium spp. and Giardia spp. were found to be common in eastern Europe, but the results from different countries are difficult to compare because of variations in reporting practices and detection methodologies used. Conclusion: Upgrading and making the diagnosis/detection procedures more uniform is recommended throughout the region. Public health authorities should actively work towards increasing reporting and standardising reporting practices as these prerequisites for the reported data to be valid and therefore necessary for appropriate control plans.

Abstract
AIMS The two components of disability-adjusted life year (DALY), years of life lost (YLL) and years lived with disability (YLD), are underutilized in evaluating heart failure with reduced ejection fraction (HFrEF) and in assessing the global burden of disease. We aim to describe both the direct (medical) and the indirect (morbidity and mortality) inpatient cost of congestive heart failure in a high-income non-Organization for Economic Cooperation and Development Middle Eastern country in relation to YLL and YLD. METHODS AND RESULTS We used the World Health Organization's global burden of disease methodology to calculate DALY, YLL, and YLD in 174 consecutive prospectively enrolled New York Heart Association Classes II-IV patients in a single-centre heart failure registry using a 0.4 disability weight and a 3% future age discount. We reported the cost of hospitalization, re-hospitalization, and non-invasive and invasive procedures per 1000 HFrEF patients in US dollars (USD). Expressing results as per 1000 HFrEF capita revealed a DALY of 1480 ± 1909 vs. 2177 ± 2547 in women and men, respectively. The costs per HFrEF capita in USD were $909.00 ± 676.1 for a single-day hospital stay, $7999 per single hospitalization, $12 311 ± 13 840 for annual hospitalizations, $20 486 ± 22 068 for all-cause hospitalizations, and $37 355 ± 49 336 from the time of diagnosis until death or recovery. CONCLUSIONS In this study, HFrEF imposed a substantial economic and disability burden on one non-Organization for Economic Cooperation and Development Middle Eastern country. However, men represented a higher economic burden than women.
