Higienização de ambiente em agroindústria familiar de embutidos cárneos / Environmental hygienization in family meat product

A higienização é um procedimento importante na indústria de alimentos e sua realização deve ocorrer rotineiramente para evitar que os alimentos sejam contaminados. Além disso, todos os manipuladores de alimentos devem receber treinamentos de modo a entender como ocorrem as contaminações e como evitá-las, para que não ocorra deterioração antecipada dos alimentos e para que não exponham os consumidores ao risco de doenças transmitidas por alimentos em caso de contaminação. Esta pesquisa avaliou o processo de higienização e sua eficiência em superfícies presentes em uma agroindústria da agricultura familiar produtora de embutidos cárneos. Apesar de ter instalações adequadas a agroindústria apresentava inadequações quanto aos produtos utilizados e a frequência inadequada para uma higienização eficiente. Foi realizada análise microbiológica das superfícies dos equipamentos para contagem de aeróbios mesófilos e notou-se uma elevada carga microbiana que indicou uma baixa eficiência no processo de higienização. Sugeriu-se melhorias na higiene ambiental associado à instrução dos colaboradores, para contribuir na promoção da qualidade dos produtos, aumento dos lucros e salvaguardando a saúde do consumidor.

Hygiene is an important procedure in the food industry, and its performance must occur routinely to prevent food from being contaminated. In addition, all food handlers must receive training in order to understand how contamination occurs and how to avoid it, so that there is no anticipated deterioration of food and that consumers are not exposed to the risk of foodborne diseases. in case of contamination by pathogenic microorganisms. Thus, this research evaluated the cleaning process and its efficiency on surfaces present in a family farming agroindustry that produces meat products, which despite having adequate facilities, had some difficulties such as product use and inadequate frequency for eficiente cleaning. After performing a microbiological analysis to count surface mesophilic aerobes, a high level of contamination was noted, relating to low efficiency in the cleaning process. Improvements in environmental hygiene are suggested, associated with the instruction of employees for the implementation of the Standard Operating Hygiene Procedure, promoting improvements in product quality, increasing profits and safeguarding consumer health.

Abstract Introduction: Patient safety culture is considered an important structural component of the services, which promotes the implementation of safe practices and the reduction of adverse events. Objective: To identify the factors associated with patient safety culture in adult intensive care units in large hospitals in Belo Horizonte. Method: Cross-sectional survey and multicenter study. A total of 168 health professionals from four units (A, B, C and D) of adult intensive care participated. The questionnaire "Hospital Survey on Patient Safety Culture" was used. The patient's level of safety culture was considered as a dependent variable, and sociodemographic and labor aspects were the independent variables. Descriptive statistics were used and a multiple logistic regression model was developed to analyze the associated factors. Results: An association was identified between the type of hospital and eleven dimensions of the safety culture. In terms of function, the doctors, nursing technicians, and nurse were related to three dimensions; gender with two dimensions, and time working in the sector with one dimension. Conclusion: It was evidenced that the type of hospital, function, time working in the sector, and gender were associated with the dimensions of patient safety culture.

Standardised Versioning of Datasets: a FAIR-compliant Proposal.

This paper presents a standardised dataset versioning framework for improved reusability, recognition and data version tracking, facilitating comparisons and informed decision-making for data usability and workflow integration. The framework adopts a software engineering-like data versioning nomenclature ("major.minor.patch") and incorporates data schema principles to promote reproducibility and collaboration. To quantify changes in statistical properties over time, the concept of data drift metrics (d) is introduced. Three metrics (dP, dE,PCA, and dE,AE) based on unsupervised Machine Learning techniques (Principal Component Analysis and Autoencoders) are evaluated for dataset creation, update, and deletion. The optimal choice is the dE,PCA metric, combining PCA models with splines. It exhibits efficient computational time, with values below 50 for new dataset batches and values consistent with seasonal or trend variations. Major updates (i.e., values of 100) occur when scaling transformations are applied to over 30% of variables while efficiently handling information loss, yielding values close to 0. This metric achieved a favourable trade-off between interpretability, robustness against information loss, and computation time.

Developing generic templates to shape the future for conducting integrated research platform trials.

BACKGROUND: Interventional clinical studies conducted in the regulated drug research environment are designed using International Council for Harmonisation (ICH) regulatory guidance documents: ICH E6 (R2) Good Clinical Practice-scientific guideline, first published in 2002 and last updated in 2016. This document provides an international ethical and scientific quality standard for designing and conducting trials that involve the participation of human subjects. Recently, there has been heightened awareness of the importance of integrated research platform trials (IRPs) designed to evaluate multiple therapies simultaneously. The use of a single master protocol as a key source document to fulfill trial conduct obligations has resulted in a re-examination of the templates used to fulfill the dynamic regulatory and modern drug development environment challenges. METHODS: Regulatory medical writing, biostatistical, and other members of EU Patient-cEntric clinicAl tRial pLatforms (EU-PEARL) developed the suite of templates for IRPs over a 3.5-year period. Stakeholders contributing expertise included academic hospitals, pharmaceutical companies, non-governmental organizations, patient representative groups, and small and medium-sized enterprises (SMEs). RESULTS: The suite of templates for IRPs based on TransCelerate's Common Protocol Template (CPT) and statistical analysis plan (SAP) should help authors navigate relevant guidelines as they create study design content relevant for today's IRP studies. It offers practical suggestions for adaptive platform designs which offer flexible features such as dropping treatments for futility or adding new treatments to be tested during a trial. The EU-PEARL suite of templates for IRPs comprises a preface, followed by the actual resource. The preface clarifies the intended use and underlying principles that inform resource utility. The preface lists references contributing to the development of the resource. The resource includes TransCelerate CPT guidance text, and EU-PEARL-derived guidance text, distinguished from one another using shading. Rationale comments are used throughout for clarification purposes. In addition, a user-friendly, functional, and informative Platform Trials Best Practices tool to support the setup, design, planning, implementation, and conduct of complex and innovative trials to support multi-sourced/multi-company platform trials is also provided. Together, the EU-PEARL suite of templates and the Platform Trials Best Practices tool constitute the reference user manual. CONCLUSIONS: This publication is intended to enhance the use, understanding, and dissemination of the EU-PEARL suite of templates for designing IRPs. The reference user manual and the associated website ( http://www.eu-pearl ) should facilitate the designing of IRP trials.

Quality-by-design ecofriendly potentiometric sensor for rapid monitoring of hydroxychloroquine purity in the presence of toxic impurities.

Hydroxychloroquine (HCQ) is prescribed to treat malaria and certain autoimmune diseases. Recent studies questioned its efficiency in relieving COVID-19 symptoms and improving clinical outcomes. This work presents a quality-by-design approach to develop, optimize, and validate a potentiometric sensor for the selective analysis of HCQ in the presence of its toxic impurities (key starting materials), namely 4,7-Dichloroquinoline (DCQ) and hydroxynovaldiamine (HND). The study employed a custom experimental design of 16 sensors with different ion exchangers, plasticizers, and ionophores. We observed the Nernstian slopes, correlation coefficients, quantification limit, response time, and selectivity coefficient for DCQ and HND. The computer software constructed a prediction model for each response. The predicted responses strongly correlate to the experimental ones, indicating model fitness. The optimized sensor achieved 93.8% desirability. It proved a slope of 30.57 mV/decade, a correlation coefficient of 0.9931, a quantification limit of 1.07 × 10-6 M, a detection limit of 2.18 × 10-7 M, and a fast response of 6.5 s within the pH range of 2.5-8.5. The sensor was successfully used to determine HCQ purity in its raw material. The sensor represents a potential tool for rapid, sensitive, and selective monitoring of HCQ purity during industrial production from its starting materials.

Critical reading of systematic review articles.

A systematic review provides an overview of primary studies investigating a given research question, e.g., the effect of a certain treatment. Individual study results are sometimes synthesised in a meta-analysis. A critical reader should consider whether the systematic review is relevant and reliable, e.g., does it follow a protocol, address the risk of bias, and consider potential heterogeneity. PRISMA 2020 guideline recommends a minimum set of items that should be reported in a systematic review article, and AMSTAR 2 and ROBIS are tools for critical appraisal of systematic reviews.
