title: Decay process of free residual chlorine concentration affected by travel time in water distribution systems

description: Abstract Chlorination is the most widely used method for disinfecting water for human consumption. While the chlorinated water travels through a distribution system, the concentration of free residual chlorine (FRC) declines depending on the natural water characteristics. This study investigated FRC decay in two types of water sources - ground and surface water - with varied concentrations of organic compounds. The travel time variable depended on water consumption patterns of both distribution systems which attend low density populations and their initial project needs. Based on mathematical simulation techniques of water quality models, the study also investigated the effects of water temperature and total organic carbon (TOC) on the kinetic constants (kb) of chlorine decay. Results show that travel time in the most critical locations in the water networks and the minimum disinfectant concentrations required at the entry points were 40 hours and 0.27-0.28 mg L-1 at Vale dos Pássaros housing complex, and 144 hours and 0.30-0.36 mg L-1 at Terras Alphaville housing complex.

title: Characteristics of ocular trauma in the United States

description: ABSTRACT Purpose: We aimed to study the characteristics of ocular trauma, an important but largely preventable global cause of blindness, in the United States. Methods: Retrospective chart review of the National Trauma Data Bank (2008-2014) was performed. All patients with ocular trauma were identified using ICD-9CM codes. The collected data were statistically analyzed with student's t-test, Chi-squared test, and logistic regression analysis performed using the SPSS software. The significance was set at p&lt;0.05. Results: It was found that 316,485 (5.93%) of the 5,336,575 admitted trauma patients had ocular injuries. Their mean (SD) age was 41.8 (23) years, and most of them were men (69.4%). Race/ethnicity distribution was White 66.1%, Black 15.1%, and Hispanic 12.3%. The common injuries were orbital 39.5% and eye/adnexa contusions 34%. Associated traumatic brain injury was present in 58.2%. The frequent mechanisms were falls 25.5%, motor vehicle accident-occupant 21.8%, and struck by/against 17.6%. Patients &lt;21 years of age had higher odds of cut/pierce injuries (OR=3.29, 95%CI=3.07-3.51) than the other age groups, those aged 21-64 years had higher odds of motor vehicle accident-cyclist (OR=4.95, 95%CI=4.71-5.19), and those &gt;65 years had higher odds of falls (OR=16.75, 95%CI=16.39-17.12); p&lt;0.001. The Blacks had a greater likelihood of firearm injuries (OR=3.24, 95%CI=3.10-3.39) than the other racial/ethnic groups, the Hispanics experienced more of cut/pierce injuries (OR=2.01, 95%CI=1.85-2.18), and the Whites experienced more of falls (OR=2.3, 95%CI=2.3-2.4); p&lt;0.001. The Blacks (OR=3.41, 95%CI=3.34-3.48) and Hispanics (OR=1.75, 95%CI=1.71-1.79) mostly suffered assaults, while the Whites suffered unintentional injuries (OR=2.78 95%CI=2.74-2.84); p&lt;0.001. Optic nerve/visual pathway injuries had the greatest association with very severe injury severity scores (OR=3.27, 95%CI=3.05-3.49) and severe Glasgow Coma Scores (OR=3.30, 95%CI=3.08-3.54); p&lt;0.001. The mortality rate was 3.9%. Conclusions: Male preponderance and falls, motor vehicle accident-occupant, and struck by/against mechanisms agree with the previous reports. The identified demographic patterns underscore the need to develop group-specific preventive measures.

title: Multimodal imaging in a patient with combined hamartoma of the retina and retina pigment epithelium

description: ABSTRACT Combined hamartoma of the retina and retinal pigment epithelium is a rare, benign intraocular tumor. Hamartoma of the retina and retinal pigment epithelium has been described in the literature as a condition presenting with variable retinal damage, ranging from partial epiretinal involvement to complete distortion of the retinal layers and retinal pigment epithelium. We report the case of an 8-year-old girl presenting with longstanding strabismus who was diagnosed with Hamartoma of the retina and retinal pigment epithelium based on multimodal imaging assessment. We explored the particular imaging findings from studies using spectral-domain optical coherence tomography, fundus autofluorescence, optical coherence tomography angiography, and fluorescein angiography.

title: Supercritical Carbon Dioxide Effect on Lipase-Catalyzed Geranyl Acetate Synthesis

description: This work provides a general insight on lipase-catalyzed synthesis of geranyl acetate through esterification of geraniol with acetic acid. Although this reaction is relatively well known, the replacement of organic solvents by supercritical fluids is fairly recent and the role of CO2 is still not completely understood. Therefore, reactions were performed with Lipozyme® RM IM and Novozym® 435 as biocatalysts, and hexane and CO2 as solvents. For similar reaction conditions, geraniol conversions obtained using hexane were much higher, rather than supercritical CO2 (scCO2, 82.9% versus 12.0% after 4 h). The results obtained indicated that CO2 might help the migration of water from the enzyme surface to reaction bulk and then to the vapor phase. Thus, by increasing the vapor phase extension, the geraniol conversion enhanced to 60.5% after 4 h. Such improvement represents one step forward to comprehend the influence of CO2, a safer and greener solvent as compared to hexane.

title: DOES SLC11A2 GENE MUTATION ASSOCIATE WITH IRON-REFRACTORY IRON-DEFICIENCY ANEMIA AFTER BARIATRIC SURGERY?

description: ABSTRACT - BACKGROUND: After bariatric surgery, if there is iron-refractory iron-deficiency anemia (IRIDA) and does not respond to supplemental iron therapy, excluding other possible etiologies, genetic changes involved in iron metabolism should be considered. AIM: This study aimed to investigate the association of both mutations 1285G-C and 1246C-T, in the SLC11A2 gene, and the etiopathogenesis of anemia refractory to iron supplementation in patients undergoing bariatric surgery using Roux-en-Y gastric bypass (RYGB). METHODS: A case-control study was conducted, in which 100 patients were evaluated as Cases Group [subdivided into (i) with Anemia and (ii) without Anemia] and 100 individuals as Controls, comprising both sexes. Inherited and acquired causes of IRIDA were excluded. DNA was extracted from leukocytes of peripheral blood, and the regions that cover both mutations have been amplified by the molecular techniques such as polymerase chain reaction/restriction fragment length polymorphism. RESULTS: The 1285G-C mutation was not determined in any of the 400 alleles analyzed. Regarding the 1246C-T mutation, the wild CC genotype was found with a higher prevalence in the Control Group (34%) (OR 0.5475; 95%CI 0.2920-1.027; p=0.0827). The mutant TT genotype was found only in the Cases Group I (with Anemia) (13%). CONCLUSION: The results show the association between 1246C-T mutation, in the SLC11A2 gene, and the etiopathogenesis of IRIDA to iron supplementation in the evaluated sample. There are differences, at the molecular level, in patients with and without IRIDA after bariatric surgery using RYGB.

title: Impacts of COVID-19 pandemic and public policies on corneal transplantations in Brazil

description: ABSTRACT Purpose: The study aimed to evaluate the impact of coronavirus disease 2019 (COVID-19) pandemic and public policies on corneal donations and transplantations in Brazil and get reliable indicators to support effective measures for improving the system of obtaining, processing, distributing, using, and controlling donated ocular tissues. Methods: A questionnaire was applied by the Brazilian office of the Pan-American Association of Eye Banks (APABO) to Brazilian Eye Banks to collect data from January to August 2020 and generate reliable indicators about the impact of the COVID-19 pandemic on corneal donations and transplantations in Brazil. Results: Data from 37 Eye Banks showed that 76.1% of the 3,060 donations and 74.5% of the 3,167 transplants occurred in the pre-pandemic period. From the 6,052 processed corneas, 71.8% were provided for therapeutic purposes: 72.9% were transplanted, 26.1% ended up being discarded (45% of which qualified for optical transplantation), and 1% remained in stock in glycerin. Of the 1,706 corneas that could not be eligible for therapeutic use, 47.9% were excluded due to tissue conditions, 43.6% for serological reasons, 6.7% due to contraindications found in clinical history after retrieval, and 1.8% for other factors. Conclusions: The negative impact of the COVID-19 pandemic on corneal donations and transplantations in Brazil resulted from the recommendation of the Health Ministry to suspend the retrieval of ocular tissues from donors in cardiopulmonary arrest for almost six months. The indicators reveal the compelling requirement for updating both the classification and cornea provision criteria by the Eye Banks and improving the Brazilian corneal distribution system.

title: Tin speciation in the blood plasma of workers occupationally exposed in a cassiterite ore processing industry

description: ABSTRACT Mining is a high-risk activity due to its dangerous processes. Tin (Sn) is obtained from cassiterite ore and mining activities expose workers to the metal. Chronic exposure to Sn may cause pneumoconiosis, gastrointestinal and hematological effects, among others. This work aimed to assess the exposure of workers to tin in a cassiterite ore processing industry, using the speciation analysis in blood plasma. Twelve subjects donated the blood samples; six were occupationally exposed to Sn. Size exclusion chromatography separated proteins in blood plasma; a graphite furnace atomic absorption spectrometer determined total tin in the plasma and eluted fractions, while SDS-PAGE determined molecular masses of proteins. Tin levels in the workers’ plasma were four times higher than in the reference individuals. After fractionation, the metal only appeared in the total inclusion volume, not being possible to confirm the binding of tin to proteins, which certainly modifies their functions and impair workers’ health. Despite that, the work process needs to change since Sn levels in the workers’ plasma pointed to metal exposure. Further works are necessary to clarify whether the metal is free or bound to small proteins in blood plasma and understand the true impact of tin on workers’ health.

title: WHY ADOPT A SUSTAINABILITY APPROACH IN CAREER STUDIES? A THEORETICAL ESSAY ABOUT THE FOUNDATIONS AND THE RELEVANCE OF THE DISCUSSION

description: ABSTRACT Sustainability has been adopted as a perspective for understanding contemporary careers, which enables an analytical view of the reality of work by including human and social impacts. This theoretical essay discusses the foundations of sustainability as a core dimension of the sustainable career concept. As its main contributions, the career sustainability perspective offers a lens for a theoretical analysis emphasizing in a systemic and procedural way, and among other factors: the dynamics of the influence of multiple contexts for the continuity of individual paths; career continuity through time movements and the choices made; the interconnectivity of the diverse actors that influences individual careers; the need for a process which allows adaptive capability to be fostered, and the creation of opportunities for sustainability.
