Abstract
Background. Portal vein thrombosis (PVT) in patients with liver cirrhosis is a common complication associated with adverse outcomes. The aim of the study was to build a predictive model for PVT in cirrhotic patients.
Materials and methods. A single centre case-control study was carried out. From the database of 1512 cirrhotic patients 94 with newly diagnosed PVT based on contrast-enhanced computed tomography were referred to the Case group. Malignant PVT was an exclusion criterion. Patients without PVT were stratified and matched according to sex, age and etiology of cirrhosis; case-control ratio was 1 : 3-4. The prevalence of PVT in the database, clinical, laboratory, instrumental parameters of the groups were evaluated. Logistic regression model was used to estimate association between variables and PVT.
Results. The overall prevalence of PVT was 6.2% with the highest rates among the patients with HBV infection 16.7%, nonalcoholic steatohepatitis 15.6%, alcohol abuse in combination with HCV infection 11.7%. The best predictive model included variables: Child-Pugh classes B-C (coefficient of regression b=1.853, р=0.001), ascites (b=0.460, р=0.003), hepatocellular carcinoma without vascular invasion (b=2.126, р=0.0001), endoscopic band ligation (b=0.774, р=0.003), transabdominal esophagogastric devascularization procedure (b=2.734, р=0.001), portal hypertensive gastropathy (b=0.793, р=0.017), portal vein diameter (b=0.203, р=0.004), and local factors ulcerative colitis flare, Clostridium difficile enterocolitis, spontaneous bacterial peritonitis, colorectal cancer, splenectomy, cholecystectomy (b=2.075, р=0.017). The model had accuracy 85.8% (95% CI 81.7-89.4%), sensitivity 55.1% (95% CI 43.4-66.4%), specificity 95% (95% CI 91.6-97.3%), and AUC 0.871 (95% CI 0.826-0.916).
Conclusion. Child-Pugh classes B-C, severe portal hypertension, hepatocellular carcinoma without vascular invasion, and local factors were estimated as risk factors of PVT in cirrhotic patients.

Este texto apresenta um ensaio teórico que tem como objetivo geral fomentar a discussão epistemológica, jurídica e sociológica acerca da Reforma Trabalhista no Brasil. Os objetivos específicos do estudo estão concentrados em: abordar a epistemologia do Direito do Trabalho, a partir da evolução histórica, dos paradigmas estruturais e de sua relação com a sociedade e explicitar as bases da flexibilização do trabalho trazidas pela Reforma Trabalhista. No campo metodológico adotou-se a pesquisa exploratória de abordagem qualitativa, valendo-se ainda da pesquisa bibliográfica e documental para o embasamento teórico e exploração do tema. Para a discussão e análise dos dados, foi adotado o método da análise de conteúdo (BARDIN, 2011). O referencial teórico se baseou em diferentes autores, que discutem Trabalho, Direito do Trabalho e a Reforma Trabalhista no Brasil, tais como: Antunes (2004, 2018); Belluzzo (2012); Cassar (2018); Delgado (2004); Martins e Rodrigues, 1999); Marx (2004); Ianni (1996), dentre outros. Os resultados sugerem que a reforma trabalhista contribui para uma maior degradação do trabalho no Brasil, na medida em que submete o trabalhador a mais insegurança e amplia a liberdade do empregador em determinar as condições de contratação, o uso da mão de obra e a remuneração do trabalho e, com efeito, impondo uma precarização estrutural e o desmonte da legislação social protetora do trabalho.Palavras-chave: Trabalho.

Objective: To evaluate the union rate of subtalar arthrodesis in smokers and nonsmokers and effect of the use of different types of autologous bone grafts. Methods: This was a retrospective study with radiological evaluation of patients with subtalar arthrosis who underwent primary arthrodesis at a reference hospital between January 2008 and December 2014. Patients with a minimum follow-up period of 12 months were included and were divided into smokers and nonsmokers with or without autologous bone grafting. Results: In total, 235 patients with a mean age of 47 years (range: 19-74 years) were evaluated, among whom 90 (40%) were smokers and 141 (60%) were nonsmokers. In 221 (94%) cases, the indication for arthrodesis was due to sequelae of calcaneal fractures. A bone graft was used in 65 (27.7%) patients. The overall union rate was 85.4%, and 14.6% of the patients progressed to pseudoarthrosis. A statistically significant difference was found in the nonunion rate in smokers (p-value=0.015 by chi-square test), especially in those who did not receive a bone graft (p-value=0.014 by chi-square test). However, no significant difference was found between smokers who received a bone graft and those who did not (p-value=0.072 by chi-square test). The union rate was related to the donor site, with pseudoarthrosis in 33.3% of surgeries with an autologous calcaneal bone graft (p-value=0.011). Conclusion: Smoking increased the likelihood of pseudoarthrosis in subtalar arthrodesis by 2.5-fold, and pseudoarthrosis is related to the autologous bone graft donor site.

This study “discusses the benefit of “addition waste paper as a “new cellulose material “in mortar mixes. A partial addition of waste paper by cement weight was achieved to produce cement composite mortar. Pulp and paper is the third major industrial dumper of air, soil and water. In recent year, paper and paperboard constitute a greater portion of many countries’ urban solid discarded generation. Beside, it increases characteristic “strength due to existence “of hydrogen links “in the microstructure of “paper. Furthermore, it consume “better thermal protection. The addition percentages “of waste paper used “in this work were (5%, 10%, 15% and 20%) by “mass of cement to measure and evaluate some “properties of the mortar produced (compressive“, direct “tensile, and flexural) strength, thermal “properties such as (thermal conductivity), and “microstructure investigation “like (scanning electron microscope “(SEM)). The results indicated that the fresh mortar “properties affected expressively with higher wastepaper percent. The mechanical properties (compression, direct tensile and flexural strength) were “reduced by increasing the content of waste paper, it reduces to (74%, 50%, and 86%) respectively, with (20%) addition of waste paper than the reference mix. Moreover, using waste “paper with different percentages “led to noticeable “decrease in thermal “conductivity, especially with increasing addition percentages.

Introduction. Polyesters of terephthalic acids are major products of organic synthesis, widely used in various industries: for packing materials production, including those for foods and medicaments. Polyesters of terephthalic acids are stable chemicals and highly toxic with cumulative eff ects. Phthalates production requires further studies. Objective. To determine hygienic and clinical functional aspects of workers’ health formation in phthalates production. Materials and methods. Special clinical functional study covered workers who first started work activity in production of terephthalic acids, purified terephthalic acid and polyethylene terephthalate over 5 years of JSC “POLYEF” exploitation. Hematologic, cytochemical, biochemical and immunologic studies covered workers with primary 5-year service in the production. Hygienic evaluation covered work conditions of workers engaged into production of terephthalic acid polyesters. Results. Th e work conditions are characterized by increased level of terephthalic acids from 1.5 to 2.8 MACs. By 5 years of service, most the workers demonstrate anemia, reticulocytosis, thrombocytopenia, eosinophilia, lymphocytosis, lower enzymatic activity. Investigations also covered the most marked and early changes in cardiovascular, nervous systems, ENT organs, locomotory system and connective tissue. Major factors infl uencing the stated disorders are acting concentrations of terephthalic acid, exceeding MAC 1.5–2.8 times; character of infl uence caused by complex of chemicals with acute and unidirectional action; occupational noise exceeding MAL of 5–21 dBA. Conclusions. General principles of occupational factors action: anemic syndrome; polymorphic regulatory disorders of metabolism; sensitization, allergization; formation of secondary immune defi ciency of cytopenia type; vegetative vascular disorders — the most fr equent and early syndrome of clinical and structural health disorders; locomotory disorders caused probably by phthalates toxicity; upper respiratory tract disorders (summarized eff ects of chemical irritants); specifi c changes associated with increased noise parameters (vegetative disorders, hypertension, neurosensory deafness, etc.).

Imaginarios del pensamiento colombiano en torno al trópico, u otra manera de ver las naciones latinoamericanas. Colombia es un país con no pocas fronteras, tanto internas como externas. Las externas han sido contorneadas, bien gracias a acuerdos, o bien luego de conflictos bélicos; mientras las internas han sido el esfuerzo de unas élites, tanto coloniales como republicanas, por identificar, medir y separar, a través de lo que Alfonso Múnera ha denominado “fronteras imaginadas”1 , todo el espacio en términos de clima. Por un lado, la región de los Andes, como espacio idílico, donde la vegetación y su entorno representan lo más cercano o parecido a Europa, y a lo cual, dicho sea de paso, había que aspirar, si se pretendía ser identificado dentro del concierto de las naciones civilizadas. Y por otro lado, está el trópico, considerado antítesis de lo que una civilización es. Este espacio, representado una y otra vez en las narraciones de científicos como Francisco José de Caldas, escritores y políticos como José María Samper, literatos como José Asunción Silva y José Eustasio Rivera y hombres de estado como Rafael Reyes, es el centro de las políticas del entorno que se plantean en el libro Una cultura de invernadero: trópico y civilización en Colombia (1808-1928), del literato colombiano y profesor de Brown University Felipe Martínez Pinzón.

The present study was done to evaluate the quality and the vitamin A fortification status of 5 types of commercial edible oils sold in Dhaka city markets. The percentages of free fatty acid (FFA), peroxide value (POV), iodine value (IV) and fatty acid composition were estimated to evaluate the quality and vitamin A content were determined to evaluate the vitamin A fortification status of 25 commercial edible oils- soybean oil, sunflower oil, rice bran oil, mustard oil and palm olein (5 brands of each) . The results revealed that FFA, POV and IV of the commercial oils analyzed were within the BSTI standard limits. The highest saturated fatty acids (SFA) values ranging from 39.85 ± 0.005 to 46.97 ± 0.002 % was found in palm olein samples and the lowest SFA values ranging from 4.56 ± 0.031 to 6.97 ± 0.096 % was found in mustard oils. On the other hand, mustard oils contained highest monounsaturated fatty acids (MUFA) ranging from 69.30 ± 0.189 to 75.87 ± 0.069 % compared to other oils analyzed. Highest polyunsaturated fatty acids (PUFA) were recorded in sunflower oils 64.78 ± 0.035% followed by soybean oils 63.25 ± 0.245%. In addition, except sunflower and mustard oils, vitamin A was found in all the soybean and rice bran oils analyzed. On the contrary, vitamin A was found only in 60% of the palm olein samples analyzed and the content was much lower than the standard value (15-30 ppm).

AbstractObjectiveTo evaluate alterations in apparent axon diameter and axon density obtained by high‐gradient diffusion MRI in the corpus callosum of MS patients and the relationship of these advanced diffusion MRI metrics to neurologic disability and cognitive impairment in MS.MethodsThirty people with MS (23 relapsing‐remitting MS [RRMS], 7 progressive MS [PMS]) and 23 healthy controls were scanned on a human 3‐tesla (3T) MRI scanner equipped with 300 mT/m maximum gradient strength using a comprehensive multishell diffusion MRI protocol. Data were fitted to a three‐compartment geometric model of white matter to estimate apparent axon diameter and axon density in the midline corpus callosum. Neurologic disability and cognitive function were measured using the Expanded Disability Status Scale (EDSS), Multiple Sclerosis Functional Composite (MSFC), and Minimal Assessment of Cognitive Function in MS battery.ResultsApparent axon diameter was significantly larger and axon density reduced in the normal‐appearing corpus callosum (NACC) of MS patients compared to healthy controls, with similar trends seen in PMS compared to RRMS. Larger apparent axon diameter in the NACC of MS patients correlated with greater disability as measured by the EDSS (r = 0.555, P = 0.007) and poorer performance on the Symbol Digits Modalities Test (r = ‐0.593, P = 0.008) and Brief Visuospatial Memory Test–Revised (r = −0.632, P < 0.01), tests of interhemispheric processing speed and new learning and memory, respectively.InterpretationApparent axon diameter in the corpus callosum obtained from high‐gradient diffusion MRI is a potential imaging biomarker that may be used to understand the development and progression of cognitive impairment in MS.

AbstractBackgroundCardiac involvement in Danon disease typically manifests as left ventricular hypertrophy (LVH) and ventricular preexcitation. This study aimed to identify patients with Danon disease among patients with LVH and concurrent electrocardiographic preexcitation.MethodsElectrocardiographic preexcitation was identified in 10 of 197 patients with unexplained LVH in whom genetic testing was performed using next‐generation sequencing.ResultsThree (3/10, 30%) patients with Danon disease were found in association with different mutations in the gene of lysosome‐associated membrane protein 2 (LAMP2). Compared to seven patients without Danon disease, these three patients presented with distinctive clinical phenotypes, including onset at an earlier age (20 ± 2 years vs. 53 ± 9 years, p < 0.001), more neurological involvements (100% vs. 0, p = 0.008), higher electrocardiographic voltages (10 ± 1 mV vs. 5 ± 1 mV, p < 0.001), wider QRS complexes (163 ± 5 ms vs. 115 ± 20 ms, p = 0.006), less common asymmetric hypertrophy (0% vs. 86%, p = 0.033), and more frequent elevation of three serum enzymes (creatine kinase, aspartate aminotransferase, and lactate dehydrogenase). Intracellular vacuoles accumulation with deficiencies of LAMP2 protein was found in both cardiac and skeletal myocytes of patients with Danon disease.ConclusionIn patients with coexistent LVH and ventricular preexcitation, Danon disease is common with distinctive clinical presentations. Comprehensive assessment of these resemble patients can provide valuable findings for early identification and clinical decision making of patients with Danon disease.

AbstractPb2+ pollution poses severe threats to human health and ecosystem. In this study, based on the waste building bricks (WBB), the TiO2@HF‐WBB was prepared for Pb2+ adsorption removal from wastewater. The adsorption of Pb2+ on TiO2@HF‐WBB followed the pseudo‐second‐order kinetics and the Freundlich isotherm model. The thermodynamic parameters indicated that the adsorption process was endothermic, spontaneous, and irreversible, and also included physical adsorption and chemical adsorption simultaneously. Ca2+ and Mg2+ had little effect on Pb2+ adsorption. The effluent of fixed‐bed was below 3 μg/L within 1,000 BV. The desorption rate could reach 90% by simple operation. The possible mechanisms included the electrostatic interaction and the complexation.Practitioner points
