RESUMO
OBJECTIVES: To evaluate gender differences in workplace violence (WPV) against physicians and nurses in Latin America. STUDY DESIGN: Cross-sectional study. METHODS: A cross-sectional electronic survey was conducted between January 11 and February 28, 2022. A prespecified gender analysis was performed. RESULTS: Among the 3056 responses to the electronic survey, 57% were women, 81.6% were physicians, and 18.4% were nurses. At least one act of violence was experienced by 59.2% of respondents, with verbal violence being the most common (97.5%). Women experienced more WPV than men (65.8% vs 50.4%; P < 0.001; odds ratio [OR]: 1.89; 95% confidence interval [CI]: 1.63-2.19). Women were more likely to report at least one episode of WPV per week (19.2% vs 11.9%, P < 0.001), to request for psychological help (14.5% vs 9%, P = 0.001) and to experience more psychosomatic symptoms. In addition, women were more likely to report having considered changing their job after an aggression (57.6% vs 51.3%, P = 0.011) and even leaving their job (33% vs 25.7%, P = 0.001). In a multivariate analysis, being a woman (OR: 1.76), working in emergency departments (OR: 1.99), and with COVID-19 patients (OR: 3.3) were independently associated with more aggressive interactions, while older age (OR: 0.95) and working in a private setting (OR: 0.62) implied lower risk. CONCLUSIONS: Women are more likely to experience WPV and to report more psychosomatic symptoms after the event. Preventive measures are urgently needed, with a special focus on high-risk groups such as women.

Strawberries are highly consumed around the world; however, the post-harvest shelf life is a market challenge to mitigate. It is necessary to guarantee the taste, color, and nutritional value of the fruit for a prolonged period of time. In this work, a nanocoating based on chitosan and ZnO nanoparticles for the preservation of strawberries was developed and examined. The chitosan was obtained from residual shrimp skeletons using the chemical method, and the ZnO nanoparticles were synthesized by the close-spaced sublimation method. X-ray diffraction, scanning electron microscopy, electron dispersion analysis, transmission electron microscopy, and infrared spectroscopy were used to characterize the hybrid coating. The spaghetti-like ZnO nanoparticles presented the typical wurtzite structure, which was uniformly distributed into the chitosan matrix, as observed by the elemental mapping. Measurements of color, texture, pH, titratable acidity, humidity content, and microbiological tests were performed for the strawberries coated with the Chitosan/ZnO hybrid coating, which was uniformly impregnated on the strawberries' surface. After eight days of storage, the fruit maintained a fresh appearance. The microbial load was reduced because of the synergistic effect between chitosan and ZnO nanoparticles. Global results confirm that coated strawberries are suitable for human consumption.
RESUMO
Recently, chitin and chitosan are widely investigated for food preservation and active packaging applications. Chemical, as well as biological methods, are usually adopted for the production of these biopolymers. In this study, modification to a chemical method of chitin synthesis from shrimp shells has been proposed through the application of high-frequency ultrasound. The impact of sonication time on the deproteinization step of chitin and chitosan preparation was examined. The chemical identities of chitin and chitosan were verified using infrared spectroscopy. The influence of ultrasound on the deacetylation degree, molecular weight and particle size of the biopolymer products was analysed. The microscopic characteristics, crystallinity and the colour characteristics of the as-obtained biopolymers were investigated. Application of ultrasound for the production of biopolymers reduced the protein content as well as the particle size of chitin. Chitosan of high deacetylation degree and medium molecular weight was produced through ultrasound assistance. Finally, the as-derived chitosan was applied for beef preservation. High values of luminosity, chromatid and chrome were noted for the beef samples preserved using chitosan films, which were obtained by employing biopolymer subjected to sonication for 15, 25 and 40 min. Notably; these characteristics were maintained even after ten days of packaging. The molecular weight of these samples are 73.61 KDa, 86.82 KDa and 55.66 KDa, while the deacetylation degree are 80.60%, 92.86% and 94.03%, respectively; in the same order, the particle size of chitosan are 35.70 µm, 25.51 µm and 20.10 µm.

The variability in the host immune response directed against dengue virus (DENV) has demonstrated the need to understand the immune response associated with protection in incident infection. The objective was to estimate the association between serostatus and the risk of incident DENV infection. We used a prospective study from 2014 to 2016 in the localities of Axochiapan and Tepalcingo, Morelos, Mexico. We recruited 966 participants, of which, according to their infection history registered were categorized in four groups. To accomplish the objectives of this study, we selected to 400 participants older than 5 years of age were followed for 2.5 years. Blood samples were taken every 6 months to measure serological status and infection by ELISA. In individuals with at least two previous infections the risk of new infection was lower compared to a seronegative group (hazard ratio adjusted 0.49, 95% CI 0.24-0.98), adjusted for age and locality. Therefore, individuals who have been exposed two times or more to a DENV infection have a lower risk of re-infection, thus showing the role of cross-immunity and its association with protection.

Resultados: Se presentan los planes de cuidado en los que se centró la intervención de enfermería en la paciente valorada. Así como la evaluación del proceso en las dimensiones de estructura, proceso y resultado. Discusión/conclusiones: El EVC secundario a ruptura de aneurisma cerebral es una situación grave y devastadora para la familia y el sistema sanitario. Por tanto, una adecuada atención de enfermería a este problema es de la mayor importancia.
Introduction: It is well acknowledged that nursing staff have the greatest interaction with patients and thus, nurses need to have sufficient knowledge and experience to identify the diverse needs, for example of those patients suffering from cerebrovascular disease. This condition can be a consequence of a ruptured aneurysm, which can in turn lead the patient to a critical status jeopardizing the financial equilibrium of his/her family and the health system. Methods: The nursing process stages were developed during the postsurgical period of a patient who underwent an aneurysm clipping. The Gordon's functional health patterns model was used to collect data, in addition to the NANDA/NIC/NOC taxonomy. Results: Care plans derived from the nursing intervention were presented, as well as the related assessment in terms of the structure, process, and results dimensions. Discussion/Conclusion: The CVE secondary to the rupture of an aneurysm is a serious and devastating situation for the patient, his/her family, and the health system, therefore, an adequate related nursing attention becomes of the most importance.

This paper focus on physicochemical changes in bio-hydroxyapatite (BIO-HAp) from bovine femur obtained by calcination at high temperatures: 520-620 (each 20 °C) at 7.4 °C/min and from 700 to 1100 °C (each 100 °C) at three heating rates: 7.4, 9.9, and 11.1 °C/min. BIO-HAp samples were obtained using a multi-step process: cleaning, milling, hydrothermal process, calcination in an air atmosphere, and cooling in furnace air. Inductively Couple Plasma (ICP) showed that the presence of Mg, K, S, Ba, Zn, and Na, is not affected by the annealing temperature and heating rate. While Scanning Electron Microscopy (SEM) images showed the continuous growth of the HAp crystals during the calcination process due to the coalescence phenomenon, and the Full Width at the Half Maximum for the X-ray patterns for temperatures up to 700 is affected by the annealing temperature and the heating rate. Through X-ray diffraction, thermal, and calorimetric analysis (TGA-DSC), a partial dehydroxylation of hydroxyapatite was found in samples calcined up to 900 °C for the three heating rates. Also, Ca/P molar ratio decreased for samples calcined up to 900 °C as a result of the dehydroxylation process. NaCaPO4, CaCO3, Ca3(PO4)2, MgO, and Ca(H2PO4)2 are some phases identified by X-ray diffraction; some of them are part of the bone and others were formed during the calcination process as a function of annealing temperature and heating rate, as it is the case for MgO.

BACKGROUND: While 18F-fluorodeoxyglucose and 18F-sodium fluoride with positron emission tomography relate with inflammation and calcification, their role in the assessment of patients with Takayasu arteritis has not yet been studied. METHODS: We present 5 patients with suspected active metabolic disease who underwent PET with 18F-fluorodeoxyglucose and 18F-sodium fluoride in order to explore the locations and correlations of 18F-fluorodeoxyglucose and 18F-sodium fluoride uptakes. Diagnosis of metabolic active disease was based on 18F-fluorodeoxyglucose uptake. RESULTS: We studied 3 female patients and 2 male patients. Median age was 29 years (min: 19 max: 63). In areas with atherosclerotic plaques, we found a negative correlation between 18F-sodium fluoride and 18F-fluorodeoxyglucose uptakes (r = -0.78) (P = .001). Meanwhile, in areas with only metabolic active disease, we found a positive correlation between 18F-sodium fluoride and 18F-fluorodeoxyglucose uptakes (r = 0.94) (P = .019). CONCLUSIONS: In Takayasu arteritis, 18F-sodium fluoride uptake can document different stages of metabolic disease, even in the absence of active metabolic disease or symptoms.

A device's instrumentation for magnetic stimulation on human lymphocytes is presented. This is a new procedure to stimulate growing cells with ferrofluid in vortices of magnetic field. The stimulation of magnetic vortices was provided at five different frequencies, from 100 to 2500 Hz and intensities from 1.13 to 4.13 mT. To improve the stimulation effects, a paramagnetic ferrofluid was added on the cell culture medium. The results suggest that the frequency changes and the magnetic field variation produce an important increase in the number of proliferating cells as well as in the cellular viability. This new magnetic stimulation modality could trigger an intracellular mechanism to induce cell proliferation and cellular survival only on mitogen stimulated cells.

ABSTRACT The aim of the present study was to analyze the influence of management systems at intensive high-tech farms and subsistence farms on the prevalence of swine gastrointestinal helminthes in metropolitan Recife and the coastal zone of the state of Pernambuco, Brazil. For such, the slaughtering process at three slaughterhouses registered with the state inspection system was followed up between July 2008 to May 2009, totaling 447 pigs from 11 properties (8 high-tech farms and 3 subsistence farms). Fecal samples were collected and the parasitological examinations were carried out using the modified McMaster technique and coproculture for identification of larvae. A questionnaire was administered to determine the management condition of each farm. Strongyloidea eggs were present in 2.5% (11/447) of the pigs, and 0.2% (1/447) were positive for Trichuris sp. Coproculture revealed that 5.5% (19/349) were positive for helminthes, 2.9% (10/349) for Hyostrongylus sp., 0.3% (1/349) for Trichostrongylus sp., 2.0% (7/349) for Oesophagostomum sp., and 0.3% (1/349) with mixed infection by Hyostrongylus and Oesophagostomum sp. The occurrence of helminthes was significantly associated (p 0.05) with helminth gender, feeding, veterinary care, quarantine, live animal trade, anti-helminth agents, water supply, water treatment, hygiene quality of stalls, dung removal frequency and knowledge regarding worms and milk spots. The percentages of positivity were significantly higher among animals on the subsistence farms.
RESUMO Objetivou-se com este trabalho analisar a influência do manejo higiênico-sanitário nos níveis de infecção por parasitos gastrintestinais em suínos de granjas tecnificadas e de subsistência abatidos na Região Metropolitana de Recife e Zona da Mata do Estado de Pernambuco. Para isso, o processo de abate de suínos em três abatedouros inscritos no sistema de inspeção estadual foi acompanhado durante o período de julho de 2008 a maio de 2009, num total de 447 suínos oriundos de 11 propriedades de municípios do Estado de Pernambuco, sendo oito granjas tecnificadas e três de subsistência. Amostras fecais foram coletadas da ampola retal no abatedouro e avaliadas pelos métodos de Gordon & Whitlock e Roberts & O´Sullivan. Realizou-se a aplicação de um questionário investigativo para conhecer a situação das granjas. Para o OPG a positividade foi de 2,7% (12/447), sendo 2,5% (11/447) para ovos tipo Strongyloidea e 0,2% (1/447) para Trichuris sp. Para a coprocultura, 5,5% (19/349) foram positivas para helmintos, sendo 2,9% (10/349) para Hyostrongylus sp., 0,3% (1/349) para Trichostrongylus sp., 2,0% (7/349) para Oesophagostomum spp. e infecção mista por Hyostrongylus sp. e Oesophagostomum spp. em 0,3% (1/349). Associação significativa (p 0,05) com a ocorrência de helmintos foi obtida para as variáveis gênero de helminto, alimentação, assistência veterinária, quarentena, comércio de animais vivos, anti-helmíntico, fonte de água, tratamento de água, qualidade de higiene das baias, limpeza das instalações e conhecimento de verminose e manchas leitosas, com percentuais de positividade significativamente mais elevados entre os animais das granjas de subsistência.

Copaiba oil is an oleoresin obtained from the Copaifera L. genus (Leguminoseae) commonly featured in anti-inflammatory recipe prescribed by Amazonian traditional medical practitioners and featured in Europe and North America pharmacopeias of the past. Chemical and anti-inflammatory activity investigations from the copaiba oils obtained from Copaifera multijuga Hayne, Copaifera cearensis Huber ex Ducke and Copaifera reticulata Ducke species have proved that, although similar, these oleoresins possess varied composition and anti-inflammatory activity. Chromatographic studies showed that the main compound among sesquiterpenes was beta-caryophyllene (57.5, 19.7 and 40.9%, respectively), followed by alpha-humulene, alpha-copaene, alpha-bergamotene, delta-cadinene, with different amounts in each oleoresin. Among the diterpenes, copalic acid was the main component from Copaifera multijuga Hayne (6.2%) and was found in all the oleoresins studied. In Copaifera cearensis Huber ex Ducke, clorechinic (11.3%) and hardwickiic acids (6.2%) were the major diterpenes while kaurenoic (3.9%) and kolavenic acids (3.4%) predominated in Copaifera reticulata Ducke. The pharmacologic effects of the three oleoresins were evaluated in vitro by measuring the NO production by murine macrophages and in vivo using the zymosan induced pleurisy model in mice. The Copaiba Oil from Copaifera multijuga Hayne (100 mg/kg) was the most potent, inhibiting both NO production and the pleurisy induced by zymosan. The oleoresins from Copaifera cearensis Huber ex Ducke and Copaifera reticulata Ducke were also able to inhibit NO production and the pleurisy but with less intensity.

A significant correlation between autoimmune diseases and premature or accelerated coronary atherosclerosis has been found. The objectives of the study were: (a) to evaluate myocardial perfusion defects in patients with autoimmune diseases by contrast echocardiography and nuclear imaging; and (b) to evaluate the prevalence of alterations in subclinical myocardial perfusion defects in autoimmune diseases. Myocardial perfusion in 37 patients was evaluated by contrast echocardiography at rest and with dobutamine and with nuclear imaging. The agreement between the two diagnostic tests at rest was 0.72 (P < 0.0001) and with dobutamine was 0.65 (P < 0.0001). The prevalence of abnormalities in myocardial perfusion in autoimmune diseases by contrast echocardiography and nuclear imaging was 27% and in patients with primary antiphospholipid syndrome was 30%. We concluded that there is a high level of agreement between contrast ecocardiography and nuclear imaging for assessment of myocardial perfusion defects in patients with autoimmune diseases, and their prevalence is similar to that reported in the literature.

Objetivo: Analizar la utilidad de la resonancia magnética para el diagnóstico morfológico en las cardiopatías congénitas complejas comparada con el ecocardiograma transtorácico. Método: Se incluyeron 45 pacientes con sospecha clínica de cardiopatía congénita grave, se les realizó una resonancia magnética y ecocardiograma transtorácico y se comparó anatomía y tamaño de cavidades cardíacas. Para el análisis se empleó estadística descriptiva y análisis de Bland-AItman para la concordancia entre ambos métodos. Resultados: No hubo diferencias significativas en mediciones obtenidas por ambos métodos, excepto en la fracción de expulsión del ventrículo izquierdo (66.56 ± 9.47 por ECO vs 52.32 ± 13.85 por RM, p = 0.0001) y la medición del diámetro de la rama izquierda de la arteria pulmonar (9.77 ± 6.80 por ECO vs 13.83 ± 8.46 por RM, p = 0.05). La sensibilidad, especificidad y los valores predictivos de la RM fueron elevados para analizar la conexión AV y VA, no así para el situs atrial y los drenajes venosos (pulmonar y sistémico) donde el ECO tiene baja resolución. La concordancia de las mediciones de la FE, índice de McGoon y tamaño del VD mostró pocos valores extremos. Conclusiones: La RM y el ECO son similares para el diagnóstico morfológico de las cardiopatías congénitas graves, pero la RM puede superar al ECO en la visualización de estructuras extracardíacas.
Objective: To analyze the usefulness of magnetic resonance for the morphological diagnosis in complex congenital cardiopathies and compare it with the transthoracic echocardiogram. Method: We included 45 patients with clinical suspicion of severe congenital cardiopathy A magnetic resonance and a transthoracic echocardiogram were performed and the anatomy and size of the cardiac cavities were compared. Descriptive statistics were used and Bland-Altman test was used to analyze concordance between both methods. Results: There were no significant differences in the measures obtained with either method, except for the left ventricle ejection fraction (66.56 ± 9.47 with ECO vs 52.32 ± 13.85 with MR, p = 0.0001) and for diameter of the left branch of the pulmonary artery (9.77 ± 6.80 with ECO vs 12.83 ± 8.46 with MR, p = 0.05). The sensitivity, specificity, and predictive values of MR were high to analyze the AV and VA connection, but not for the atrial sinus and the venous drainages (pulmonary and systemic). Concordance of ejection fraction measures, McGoon index, and size of VD revealed few extreme values. Conclusions: MR and ECO are similar for the morphological diagnosis of severe congenital cardiopathies, but MR can be better than ECO for the visualization of extracardiac structures.
