Published: March 2023

Este artigo aborda as experiências das catadoras de materiais recicláveis diante das implicações provocadas pela pandemia da COVID-19 em uma associação no Distrito Federal (DF). O objetivo principal foi compreender a situação de vida precária das mulheres catadoras inseridas em uma desigualdade sistêmica e institucional do capitalismo. Para tanto, foi realizada uma etnografia que combinou técnicas de observação, interação e escuta (conversas informais e entrevistas semiestruturadas). Através disso, permitiu-se o acompanhamento do cotidiano de vida dessas mulheres, desde a instauração de uma das maiores crises sanitária da humanidade até o período do retorno às atividades laborais. Os resultados revelaram que as catadoras estão inseridas na lógica de precarização da vida, sendo que as condições foram agravadas com a chegada do novo coronavírus quando aumentou a vulnerabilidade relacionada ao vínculo de trabalho informal, a insalubridade e os riscos à saúde inerentes à ocupação e às dificuldades de acesso aos serviços de saúde e assistência social. O contexto mostra uma lida complexa relacionada ao medo do desemprego, às dificuldades e às barreiras do ingresso no mercado de trabalho e de manutenção da própria subsistência. Sobretudo, isso agravou-se de forma mais intensa diante da ausência de políticas e programas voltados para elas: o Estado fez pouco para a redução dos impactos da pandemia em suas vidas. Assim, a crise sanitária instaurada refletiu a fragilidade delas em face ao ciclo da reciclagem. Este fato demonstra a necessidade urgente de ações governamentais que abarquem esse grupo social tanto no momento da pandemia quanto pós-pandemia da COVID-19, visando superar a invisibilidade social.

Camellia oleifera Abel. (C. oleifera), one of the four woody oil-producing plants in the world produces edible oils with high percentage of unsaturated fatty acid content in seeds. The mature C. oleifera seeds continue to undergo a series of physiological changes after harvest. To this end, the dynamic changes in nutrients, oil content, fatty acid composition, and endogenous hormone content in C. oleifera seeds under different natural drying times after harvest were investigated. The content of soluble sugar and soluble protein of C. oleifera seeds increased with the extension of natural drying, especially soluble sugar content increased nearly 2-fold at 30 d after post-harvest natural drying compared with that of the control group. The content of oil reached a peak (23.6%) at 30 d after post-harvest natural drying. During the post-harvest natural drying process, the relative content of palmitic acid and oleic acid increased, while the relative content of palmitic acid and linoleic acid decreased. Furthermore, the levels of unsaturated fatty acids (oleic acid, linoleic acid, linolenic acid, and arachidonic acid) increased significantly with increasing natural drying time. The overall trend of endogenous hormones SA, SL, and ACC concentrations increased with the post-harvest natural drying process. Furthermore, the concentration of SA, SL, and ACC were positively correlated with oil content. Altogether, post-harvest natural drying for 30 days significantly promoted the anabolism of oil and improved the quality of C. oleifera seeds. These findings provide a scientific basis for reasonable post-harvest treatment to improve Camellia oil yield.

Abstract
Background: Assessment of kidney function in emergency settings is essential across all medical subspecialties. Daily assessment of patient creatinine result from emergency medical services showed that some creatinine results apparently deviated from expected creatinine values implying occurrence of drug-related interferences.
Methods: Real-time clinical evaluation of an enzyme method (Roche CREP2) in comparison to Jaffé gen. 2 method (Roche CREJ2) was performed. During the period of December 2022 and January 2023 we analyzed 8498 paired patient specimens, 5524 were heavily medicated STAT patient specimens, 500 were pediatric specimens and 2474 were analyzed in a distant general population in a different region using the same methods.
Results: About 2 percent of hospital specimens with patient history showed apparent drops of creatinine concentrations with the enzyme method against the compensated Jaffé method. Suspect medication was found in 43 out of 46 reviewed patients where medication data were allowed for review. A general patient cohort showed no drops of concentrations measured by the enzyme method. Pediatric hospital cohort showed 6 drops out of 500 total measurements.
Conclusions: We implemented immediate corrective measures that were replacement of enzyme creatinine with Jaffé gen.2 method, the “full Schwartz” composite formula for pediatric medicine and CKD-EPI with cystatin C for STAT adult medical services. We conclude that pharmacotherapy-induced inaccuracies with enzyme creatinine methods imply the need for proper method validations in the relevant patient population and may facilitate introduction of cystatin C to emergency medicine clinical practice.

Off the Diagonal of Institutional Development
Authors: Murphy Ryan H. 
Published: March 2023

Abstract
Three characteristics of developed twenty-first century countries are high levels of state capacity, democracy, and economic freedom. This paper explores which countries do not possess one of the characteristics relative the levels of the others. We find that countries which lack democracy are those with other means to secure political legitimacy, and those without strong states are geographically concentrated in Latin America and Eastern Europe. Those without liberalized economic institutions are an idiosyncratic group that are best described as having unconventional historical paths. These findings speak to the prospects for development outside the liberal democratic path, the nature of development in the absence of a state, and unexplored determinants of economic freedom.

Published: March 2023

Abstract
One of the suitable solutions for burning natural gas in diesel engines is the use of dual fuel technology. In this study, the MT440C compression ignition engine has been converted to dual fuel (Diesel + CNG) simultaneously combustion of diesel fuel and natural gas, with the least amount of engine changes and using the most amount of natural gas. The ignition of the engine was in the range of the governor. Experiments in stable conditions for the working modes of the engine were performed with pure diesel fuel and mixed gas diesel fuel. The effects of natural gas fuel as the main fuel and diesel fuel as the spark ignition on a 4-cylinder CI engine were investigated on the performance and emissions. According to the engine speed and load, the amount of diesel fuel was adjusted using mechanical changes in the governor, while the ignition system was not used. These tests were performed at engine speeds of 1200, 1400, 1600, 1800, and 2000 rpm, using diesel fuel and dual fuel. These data were collected in the Engine Research Center of Tabriz Motorsazan Company and experimental runs were repeated 3 times One of the goals of this research is to reduce the consumption of diesel fuel, and in the current study, CNG is 72% and diesel is 28% of the dual fuel in idling. This study showed that the emission of some pollutants increased and some decreased in the dual fuel mode. Therefore, more research is needed on modifying the diesel injection system as a spark plug or the CNG injection system to reduce the emission of greenhouse gases.

Published: March 2023

Abstract
Backgrounds: Patients with hematological cancers and their caregivers request more realistic information about disease trajectory and prognosis. The aim of the study was to evaluate the implementation of an adapted SICP concept into the hematological department at Copenhagen University Hospital in Denmark.
Methods: For evaluating the adaptation and implementation of the SICP the outlined framework in the updated guidelines for complex interventions by the UK Medical Research Council was used combined with an action research design with 5 haematological doctors, 5 nurses, 6 patients with haematological malignancies, and 4 caregivers. For evaluating the effectiveness of the adapted concept as well as understanding the processes of change, a combination of quantitative and qualitative methods was performed with two questionnaire scales, focus group, and dyad interviews.
Results: There were no significant correlations between before and after on either of the two scales. Among the individual questions within the two scales, seven questions showed significant difference from before to after the course or between participants and control group. The analysis of the questionnaire data points to that participants might increase confidence in their own abilities to include existential aspects in patient care and make changes in care plan, if needed. It also seemed that nurses and doctors who found it important to care for patients’ existential concerns and believe this to be an important part of their job were more likely to participate in the SICP concept. The qualitative analysis points to the importance of interdisciplinarity of the nurse and doctor in the SICP because then the patient’s and caregiver’s preferences are integrated in the treatment and care plan, and it strengthens conversations involving medical, holistic, and existential issues. It particularly seemed how time allocated for the conversation and the preparatory materials for the conversations highly influenced outcome of the conversation.
Conclusions: The implementation of adapted SICP is feasible in a hematological setting, and it facilitated overcoming barriers for offering more existential consultations in hematology. SICP concept have been implemented to all staff members of the myeloma/lymphoma clinic and to be integrated timely throughout the disease trajectory starting at the time of diagnosis.

Abstract
Background: Endometriosis can affect the systemic metabolic indicators, including body mass index, glucose metabolism and lipid metabolism, while the association between metabolic indexes and the occurrence and ART outcome of endometriosis is unclear. We aimed to evaluate the characteristics of systemic metabolic indexes of endometriosis patients with infertility and their effects on pregnancy outcome after ART treatment.
Methods:A retrospective cohort study involve 412 endometriosis patients and 1551 controls was conducted. Primary outcome was metabolic indexes, and secondary measures consisted of the influence of metabolic indexes on the number of retrieved oocytes and ART outcomes, as well as the relation between blood glucose and prevalence of GDM.
Results:Endometriosis patients had higher INS [6.90(5.10-9.50) vs 6.50(4.80-8.90) μU/mL, P = 0.005]. A prediction model for endometriosis combining the number of previous pregnancies, CA125, fasting blood Glu and INS, had a sensitivity of 73.9%, specificity of 67.8% and area AUC of 0.77. There were no significant differences in ART outcomes and complications. The levels of Glu were associated with GDM both in endometriosis group (aOR 12.95, 95% CI 1.69–99.42; P = 0.014) and in control group (aOR 4.15, 95% CI 1.50–11.53; P = 0.006).
Conclusions: Endometriosis patients had abnormal metabolic indexes, in which serum Glu and serum INS are related to the occurrence of endometriosis, the number of retrieved oocytes and the occurrence of GDM. A prediction model based on metabolic indexes was established, representing a promising non-invasive method to predict endometriosis patients with known pregnancy history.

Abstract
At present, people are in the era of big data, which is changing people's views of the world. However, it has the characteristics of various types, huge scale, and complex relationships. In order to solve the repeated calculation caused by streaming data in the processing of tensor-based big data, there will also be dimension disasters. Therefore, in this paper, an incremental tensor train decomposition (ITTD) method is proposed to solve multi-clustering problem in tensor-based big data analysis systems. It mainly uses results of the tensor train decomposition obtained from the original tensor to calculate and updates the results of tensor train decomposition to avoid the repetitive decomposition of the original tensor and enhance the decomposition efficiency. The performance of ITTD method is tested through theoretical analysis, a large number of simulation data and a comparative experiment on the real data of public transportation in a region. The experimental results indicate that the execution time of ITTD is significantly shorter than that of nonincremental tensor train decomposition(NTTD) with time. However, as time goes by, there is no obvious difference in the approximation error and storage space between the two.. This shows that, compared to that of the traditional nonincremental method, if the approximation error and storage space are close, the execution time of the incremental method will be greatly shortened. It can improve the processing efficiency of multi-clustering problems in the tensor-based big data analysis system.

Published: March 2023

Abstract

Background: Intraoperative hyperglycemia is a common problem among patients undergoing orthopedic surgery. Its incidence varies from country to country and not clearly studied in developing countries.
Method:Multi-center cross-sectional study was conducted on eligible adult elective patients who underwent orthopedic surgical procedures. The participants were selected using a systematic random sampling technique. Data was collected on basic characteristics, medical and surgical history. On the arrival of patients to the OR, blood glucose was measured and recorded and repeated after administering anesthesia. The data was analyzed using descriptive statistics and bivariate and multivariate logistic regression. P<0.05 was considered as statistically significant.
Results: Intraoperative hyperglycemia was observed in 20.4% of patients. Hypothermia (AOR:2.45;95% CI:0.97-6.27, p=0.05), infused dextrose iv fluids (AOR:2.94;95% CI:1.64-5.16, p=0.05) , blood transfusion (AOR:6.64;95% CI:2.92-15.08, p=0.00) and history of hypertension (AOR:2.19;95% CI:1.23-3.71, p=0.01) were factors identified to be associated with intraoperative hyperglycemia.
Conclusions and recommendations
This study showed the magnitude of intraoperative hyperglycemia was high. Anesthetists should identify all risk factors preoperatively and make appropriate adjustments for patient care. Hypertension should be optimized, refrain from routine administering of dextrose IV fluids, and unnecessary transfusions, as well as monitor patients’ body temperature.

Published: March 2023

Abstract
Resistance of bacteria to current antibiotic drugs and the reoccurrence of different ailments after several therapeutic protocols have continued to be a cause of concern. Arylated amino acids are vital synthons to many compounds, they serve as essential building blocks in the synthesis of nitrogen heterocycles with various biological activities. This research reports the synthesis of some N-aryl amino acids and evaluates their antibacterial activities. The N-aryl amino acids 3a-3j were obtained by reacting different 4-substituted fluorobenzene 1a-1d with different amino acids 2a-2g via a metal-free, base-induced aryl amination reaction of aryl halides. The antibacterial activities of the synthesised compounds were evaluated against eight bacterial strains (Four gram-positive: Bacillus subtilis (ATCC 6633), Streptococcus pneumonia (ATCC 33400), Staphylococcus aureus (ATCC 25923), Staphylococcus epidermidis (ATCC 14990) and four gram-negative: Enterobacter cloacae (ATCC 43560), Escherichia coli (ATCC 25922), Proteus mirabilis (ATCC 43071) and Klebsiella oxytoca (ATCC 13182) using the agar well diffusion method with streptomycin as a reference drug. The biological screening indicates the synthesised compounds 3a, 3e, and 3j have promising broad-spectrum antibacterial potential as the N-aryl amino acid displayed comparable to better activity with the standard drug against Streptococcus pneumonia, Escherichia coli, and Proteus mirabilis.

Abstract

This study evaluated microbial safety (incidence, risk levels and prevalence) of fresh produce from three states in 30 open-markets in Southwest, Nigeria. Total Viable Count of Enteriobacteriacaea, coliforms and Listeria (using four broths and five agar) were done on homogenised samples (n = 180). Epiphytes prevalence decrease with cabbage from [Ondo (4.33%), Lagos (3.52%), Osun (2.71)]; carrot [Osun (2.80%), Lagos (2.26%) and Ondo (1.81%)]; cucumber [Ondo (3.52%), Osun (3.25%) and Lagos (2.89%)]; garden egg and tomato [Lagos (4.15% and 3.61%), Osun (2.17% and 2.89%) and Ondo (1.71% and 2.44) respectively]; watermelon and all fresh produce [Lagos (2.98% and 19.40%), Ondo (1.99% and 15.79%) and Osun (1.71% and 15.52) respectively]. PALCAM and XLD agar have highest isolation rate, sensitivity, differential ability and effectiveness but low selectivity. Tomato from Lagos State markets showed 0.00x100 cfu/g on VRBG, BGA and XLD. Fresh produce epiphytes prevalence increased in Lagos from [carrot (2.26%), cucumber (2.89%), watermelon (2.98%), cabbage (3.52%), tomatoes (3.61%) to garden egg (4.15%)]; Osun State [water melon (1.71%), garden egg (2.17%), cabbage (2.71%), carrot (2.80%), tomatoes (2.89%) to cucumber (3.25%)]; in Ondo State [garden egg (1.71%), carrot (1.81%), watermelon (1.99%), tomatoes (2.44%) cucumber (3.52%) to cabbage (4.33%)]. Hence, fresh produce are route of food poisoning.
