Características físico-químicas do mel comercializado na região de UberlândiaPhysicochemical properties of honey marketed in Uberlandia region

Além de sua qualidade como alimento, o mel é dotado de numerosas propriedades terapêuticas, sendo utilizado pela medicina popular como fitoterápico sob diversas formas e associações. Durante o transcorrer dos tempos, esse excepcional alimento vem sendo fraudado, com a busca de lucros fáceis, o que pode comprometer a segurança alimentar, consequentemente a saúde dos consumidores e, baseado neste fato, este trabalho teve como objetivo verificar a qualidade de amostras de mel, na região de Uberlândia. As análises físico-químicas realizadas nas amostras de mel, em duas repetições, foram as exigidas pela Instrução Normativa no 11 de 20 de Outubro de 2000, sendo elas; acidez, açúcares redutores, atividade diastásica, cinzas, hidroximetilfurural, sacarose aparente, sólidos insolúveis em água e umidade. Foram analisadas 10 (dez) amostras de mel, sendo quatro com registro da S.I.F.; três com rótulo e assinatura do técnico responsável e três artesanais. Das dez amostras de mel analisadas, 100% atendiam à Normativa no 11 quanto aos parâmetros umidade, cinzas e acidez, 10% apresentaram teor de sólidos insolúveis em água superior ao permitido, 30% apresentaram teor de açúcares redutores inferior ao exigido e 60% apresentaram teor de sacarose aparente superior ao estabelecido pela Normativa no 11. Entre as amostras analisadas, as 3 (três) que mais apresentaram parâmetros em desacordo com a Instrução Normativa no 11 foram as amostras de mel artesanal, portanto sem registro da S.I.F. e sem rótulo com assinatura do técnico responsável e 1 (uma) amostra de mel com rótulo e assinatura do técnico responsável.Abstract Besides its quality as food, honey is endowed with numerous therapeutic properties and is used in folk medicine as a herbal medicine in various forms and associations. During the course of time, this exceptional food has been rigged, with the search for easy profits, which may compromise food security, thus the health of consumers and, based on this fact, this study aimed to verify the quality of samples honey, in this city. The physicochemical analyzes in honey samples in duplicate, were those required by Instruction No 11 of 20 October 2000, as follows; acidity, reducing sugars, diastase activity, ashes, hidroximetilfurural, apparent sucrose, solid insoluble in water and moisture. We analyzed ten (10) samples of honey, four with registration of the SIF; three with label and signature of the technician responsible and three handmade. Of the ten samples of honey analyzed, 100% met the Normative No 11 as the humidity parameters, ash and acidity, 10%, solid content insoluble in water above the allowed 30% were reducing sugar content than required and 60% had apparent sucrose content higher than that stated by the Normative 11. Among the samples analyzed, the three (3) showed that more parameters at odds with the Instruction # 11 were samples of artisanal honey, so no record of SIF and unlabeled signed by the technical manager and one (1) Honey sample label and signature of the technician responsible

La imagen y la narrativa como herramientas para el abordaje psicosocial en escenarios de violencia. Bogotá, Chía, Cali, Bordo Patía, y Bolívar. Departamentos Cundinamarca, Valle, Cauca

Buitrón, A. (5/11/2023). Aplicación de la Imagen y la Narrativa Enlace de Video https://youtu.be/J2mtZ5CkfVo?si=7w6dqOhDtj4dQQ9hLas victimas a través de las narrativas, buscan reconstruirse a través de un espacio que les permita visibilizarse y hacer transformaciones en sus comunidades, las cuales han sido afectadas por los diferentes fenómenos que ha traído consigo el conflicto armado en Colombia. Esto ha permitido la recuperación emocional y la mitigación de los daños de distintos hechos de violencia, fortaleciendo sus redes sociales al reconstruirse su tejido social. Al visibilizar las diferentes experiencias, se hace conciencia frente a su realidad y se reconoce la oportunidad de cambio que la crisis les ofrece, afrontándolo en términos comunitarios y dando sentido al redescubrimiento el ser como único, trascendente y responsable de sus decisiones, reconociendo la capacidad de reconstruirse en un nuevo escenario. De esta manera, el presente trabajo pretende resaltar estrategias y hacer una profunda reflexión que desde el que hacer como futuros profesionales en psicología de la UNAD, proponemos con el ánimo de minimizar las consecuencias, acabar con las estigmatizaciones, propender por la no repetición y coayudar a la reconstrucción del tejido social, resaltando factores protectores invisibilizados por tantos hechos violentos y que hoy se debe retomar para poder salir adelante al logro de una paz con justicia social.The victims, through the narratives, seek to rebuild themselves through a space that allows them to make themselves visible and make transformations in their communities, which have been affected by the different phenomena that the armed conflict in Colombia has brought with it.This has allowed emotional recovery and mitigation of damage from different acts of violence, strengthening their social networks by rebuilding their social fabric. By making the different experiences visible, they become aware of their reality and recognize the opportunity for change that the crisis offers them, facing it in community terms and giving meaning to the rediscovery of the self as unique, transcendent and responsible for its decisions, recognizing the capacity to rebuild in a new scenario. In this way, the present work aims to highlight strategies and make a deep reflection that from what to do as future professionals in psychology at UNAD, we propose with the aim of minimizing the consequences, ending stigmatization, promoting non-repetition and helping to the reconstruction of the social fabric, highlighting protective factors made invisible by so many violent events and that must be resumed today in order to move forward to achieve peace with social justice

Persona y felicidad Aportes desde la educación, la filosofía, la historia, la ética, la política, el derecho y la bioética

El libro recoge una colección de artículos producto de investigaciones adelantadas por docentes del Departamento de Humanidades y cuyo centro temático es la relación entre las personas y la felicidad. Cada capítulo brinda respuestas desde un ámbito específico disciplinar, a través de una metodología cualitativa, al problema antropológico y ético de la consecución de la felicidad o la realización humana personal. Desde la educación y la ética se plantea la transición de unas humanidades informativas a otras performativas, que integren formación moral y valores sobrenaturales, que aboguen por la empatía y la solidaridad como camino humano de felicidad. A partir de las claves antropológicas de Leonardo Polo se presenta a la persona como ser capaz de dotar de sentido su modo de estar en el mundo, más allá de la propia satisfacción felicitaria, pues ella misma es un sentido personal capaz de manifestarse en la tarea esperanzada. Así mismo, desde la antropología personalista se estudia la felicidad como proyecto de vida, pasando de la conflictividad hacia la espiritualidad y proponiendo decantadas transformaciones político-educativas. En el ámbito de las ciencias históricas se analiza el uso de los conceptos de persona y felicidad en el Magisterio de Juan xxiii subrayando las perspectivas sugeridas por el Papa y recogidas por los pontífices sucesivos. Desde el derecho se analiza la relación entre justicia y felicidad, aplicada al llamado “derecho a morir dignamente”; y desde la bioética se plantean reflexiones sobre procreación y felicidad a partir del debate actual sobre la maternidad subrogada.Prólogo.

Antimicrobial resistance among migrants in Europe: a systematic review and meta-analysis

BACKGROUND: Rates of antimicrobial resistance (AMR) are rising globally and there is concern that increased migration is contributing to the burden of antibiotic resistance in Europe. However, the effect of migration on the burden of AMR in Europe has not yet been comprehensively examined. Therefore, we did a systematic review and meta-analysis to identify and synthesise data for AMR carriage or infection in migrants to Europe to examine differences in patterns of AMR across migrant groups and in different settings. METHODS: For this systematic review and meta-analysis, we searched MEDLINE, Embase, PubMed, and Scopus with no language restrictions from Jan 1, 2000, to Jan 18, 2017, for primary data from observational studies reporting antibacterial resistance in common bacterial pathogens among migrants to 21 European Union-15 and European Economic Area countries. To be eligible for inclusion, studies had to report data on carriage or infection with laboratory-confirmed antibiotic-resistant organisms in migrant populations. We extracted data from eligible studies and assessed quality using piloted, standardised forms. We did not examine drug resistance in tuberculosis and excluded articles solely reporting on this parameter. We also excluded articles in which migrant status was determined by ethnicity, country of birth of participants' parents, or was not defined, and articles in which data were not disaggregated by migrant status. Outcomes were carriage of or infection with antibiotic-resistant organisms. We used random-effects models to calculate the pooled prevalence of each outcome. The study protocol is registered with PROSPERO, number CRD42016043681. FINDINGS: We identified 2274 articles, of which 23 observational studies reporting on antibiotic resistance in 2319 migrants were included. The pooled prevalence of any AMR carriage or AMR infection in migrants was 25·4% (95% CI 19·1-31·8; I2 =98%), including meticillin-resistant Staphylococcus aureus (7·8%, 4·8-10·7; I2 =92%) and antibiotic-resistant Gram-negative bacteria (27·2%, 17·6-36·8; I2 =94%). The pooled prevalence of any AMR carriage or infection was higher in refugees and asylum seekers (33·0%, 18·3-47·6; I2 =98%) than in other migrant groups (6·6%, 1·8-11·3; I2 =92%). The pooled prevalence of antibiotic-resistant organisms was slightly higher in high-migrant community settings (33·1%, 11·1-55·1; I2 =96%) than in migrants in hospitals (24·3%, 16·1-32·6; I2 =98%). We did not find evidence of high rates of transmission of AMR from migrant to host populations. INTERPRETATION: Migrants are exposed to conditions favouring the emergence of drug resistance during transit and in host countries in Europe. Increased antibiotic resistance among refugees and asylum seekers and in high-migrant community settings (such as refugee camps and detention facilities) highlights the need for improved living conditions, access to health care, and initiatives to facilitate detection of and appropriate high-quality treatment for antibiotic-resistant infections during transit and in host countries. Protocols for the prevention and control of infection and for antibiotic surveillance need to be integrated in all aspects of health care, which should be accessible for all migrant groups, and should target determinants of AMR before, during, and after migration.

Search for dark matter produced in association with bottom or top quarks in √s = 13 TeV pp collisions with the ATLAS detector

A search for weakly interacting massive particle dark matter produced in association with bottom or top quarks is presented. Final states containing third-generation quarks and miss- ing transverse momentum are considered. The analysis uses 36.1 fb−1 of proton–proton collision data recorded by the ATLAS experiment at √s = 13 TeV in 2015 and 2016. No significant excess of events above the estimated backgrounds is observed. The results are in- terpreted in the framework of simplified models of spin-0 dark-matter mediators. For colour- neutral spin-0 mediators produced in association with top quarks and decaying into a pair of dark-matter particles, mediator masses below 50 GeV are excluded assuming a dark-matter candidate mass of 1 GeV and unitary couplings. For scalar and pseudoscalar mediators produced in association with bottom quarks, the search sets limits on the production cross- section of 300 times the predicted rate for mediators with masses between 10 and 50 GeV and assuming a dark-matter mass of 1 GeV and unitary coupling. Constraints on colour- charged scalar simplified models are also presented. Assuming a dark-matter particle mass of 35 GeV, mediator particles with mass below 1.1 TeV are excluded for couplings yielding a dark-matter relic density consistent with measurements

Surgical site infection after gastrointestinal surgery in high-income, middle-income, and low-income countries: a prospective, international, multicentre cohort study

Background: Surgical site infection (SSI) is one of the most common infections associated with health care, but its importance as a global health priority is not fully understood. We quantified the burden of SSI after gastrointestinal surgery in countries in all parts of the world. Methods: This international, prospective, multicentre cohort study included consecutive patients undergoing elective or emergency gastrointestinal resection within 2-week time periods at any health-care facility in any country. Countries with participating centres were stratified into high-income, middle-income, and low-income groups according to the UN's Human Development Index (HDI). Data variables from the GlobalSurg 1 study and other studies that have been found to affect the likelihood of SSI were entered into risk adjustment models. The primary outcome measure was the 30-day SSI incidence (defined by US Centers for Disease Control and Prevention criteria for superficial and deep incisional SSI). Relationships with explanatory variables were examined using Bayesian multilevel logistic regression models. This trial is registered with ClinicalTrials.gov, number NCT02662231. Findings: Between Jan 4, 2016, and July 31, 2016, 13 265 records were submitted for analysis. 12 539 patients from 343 hospitals in 66 countries were included. 7339 (58·5%) patient were from high-HDI countries (193 hospitals in 30 countries), 3918 (31·2%) patients were from middle-HDI countries (82 hospitals in 18 countries), and 1282 (10·2%) patients were from low-HDI countries (68 hospitals in 18 countries). In total, 1538 (12·3%) patients had SSI within 30 days of surgery. The incidence of SSI varied between countries with high (691 [9·4%] of 7339 patients), middle (549 [14·0%] of 3918 patients), and low (298 [23·2%] of 1282) HDI (p < 0·001). The highest SSI incidence in each HDI group was after dirty surgery (102 [17·8%] of 574 patients in high-HDI countries; 74 [31·4%] of 236 patients in middle-HDI countries; 72 [39·8%] of 181 patients in low-HDI countries). Following risk factor adjustment, patients in low-HDI countries were at greatest risk of SSI (adjusted odds ratio 1·60, 95% credible interval 1·05–2·37; p=0·030). 132 (21·6%) of 610 patients with an SSI and a microbiology culture result had an infection that was resistant to the prophylactic antibiotic used. Resistant infections were detected in 49 (16·6%) of 295 patients in high-HDI countries, in 37 (19·8%) of 187 patients in middle-HDI countries, and in 46 (35·9%) of 128 patients in low-HDI countries (p < 0·001). Interpretation: Countries with a low HDI carry a disproportionately greater burden of SSI than countries with a middle or high HDI and might have higher rates of antibiotic resistance. In view of WHO recommendations on SSI prevention that highlight the absence of high-quality interventional research, urgent, pragmatic, randomised trials based in LMICs are needed to assess measures aiming to reduce this preventable complication

Impact of COVID-19 on cardiovascular testing in the United States versus the rest of the world

Objectives: This study sought to quantify and compare the decline in volumes of cardiovascular procedures between the United States and non-US institutions during the early phase of the coronavirus disease-2019 (COVID-19) pandemic. Background: The COVID-19 pandemic has disrupted the care of many non-COVID-19 illnesses. Reductions in diagnostic cardiovascular testing around the world have led to concerns over the implications of reduced testing for cardiovascular disease (CVD) morbidity and mortality. Methods: Data were submitted to the INCAPS-COVID (International Atomic Energy Agency Non-Invasive Cardiology Protocols Study of COVID-19), a multinational registry comprising 909 institutions in 108 countries (including 155 facilities in 40 U.S. states), assessing the impact of the COVID-19 pandemic on volumes of diagnostic cardiovascular procedures. Data were obtained for April 2020 and compared with volumes of baseline procedures from March 2019. We compared laboratory characteristics, practices, and procedure volumes between U.S. and non-U.S. facilities and between U.S. geographic regions and identified factors associated with volume reduction in the United States. Results: Reductions in the volumes of procedures in the United States were similar to those in non-U.S. facilities (68% vs. 63%, respectively; p = 0.237), although U.S. facilities reported greater reductions in invasive coronary angiography (69% vs. 53%, respectively; p < 0.001). Significantly more U.S. facilities reported increased use of telehealth and patient screening measures than non-U.S. facilities, such as temperature checks, symptom screenings, and COVID-19 testing. Reductions in volumes of procedures differed between U.S. regions, with larger declines observed in the Northeast (76%) and Midwest (74%) than in the South (62%) and West (44%). Prevalence of COVID-19, staff redeployments, outpatient centers, and urban centers were associated with greater reductions in volume in U.S. facilities in a multivariable analysis. Conclusions: We observed marked reductions in U.S. cardiovascular testing in the early phase of the pandemic and significant variability between U.S. regions. The association between reductions of volumes and COVID-19 prevalence in the United States highlighted the need for proactive efforts to maintain access to cardiovascular testing in areas most affected by outbreaks of COVID-19 infection
