Authors: ROSSI Lucas Félix , TRINDADE Manoel Roberto Maciel , D`ACAMPORA Armando José , MEURER Luise
Published: August 2017

ABSTRACT Background: Hernia correction is a routinely performed treatment in surgical practice. The improvement of the operative technique and available materials certainly has been a great benefit to the quality of surgical results. The insertion of prostheses for hernia correction is well-founded in the literature, and has become the standard of treatment when this type of disease is discussed. Aim: To evaluate two available prostheses: the polypropylene and polypropylene coated ones in an experimental model. Methods: Seven prostheses of each kind were inserted into Wistar rats (Ratus norvegicus albinus) in the anterior abdominal wall of the animal in direct contact with the viscera. After 90 days follow-up were analyzed the intra-abdominal adhesions, and also performed immunohistochemical evaluation and videomorphometry of the total, type I and type III collagen. Histological analysis was also performed with hematoxylin-eosin to evaluate cell types present in each mesh. Results: At 90 days the adhesions were not different among the groups (p=0.335). Total collagen likewise was not statistically different (p=0.810). Statistically there was more type III collagen in the coated polypropylene group (p=0.039) while type I was not different among the prostheses (p=0.050). The lymphocytes were statistically more present in the polypropylene group (p=0.041). Conclusion: The coated prosthesis was not different from the polypropylene one regarding the adhesion. Total and type I collagen were not different among the groups, while type III collagen was more present on the coated mesh. There was a greater number of lymphocytes on the polypropylene mesh.

Published: August 2017

ABSTRACT Background: MTUYH and OGG1 genes have importance in the base excision repair systems of oxidized DNA bases. Modification of the tissue expression of these genes is related to the increased risk of developing colorectal cancer. Aim: To evaluate the tissue expression of MUTYH and OGG1 comparing normal and neoplastic tissues of patients with sporadic colorectal cancer and to correlate it with clinical and histopathological variables. Method: MUTYH and OGG1 tissue expression was quantified by RT-PCR in patients with colorectal cancer and the values were compared in normal and neoplastic tissues. MUTYH and OGG1 expression was measured and normalized to the constitutive 18S gene. The level of expression of both genes was correlated with the variables: age, gender, tumor location, size of the tumor, histological type, degree of cell differentiation, invasion depth in the intestinal wall, angiolymphatic infiltration, lymph node involvement and TNM staging. Results: Was found downregulation of both genes in neoplastic when compared to normal tissue. There was downregulation of the MUTYH in larger tumors and in patients with angiolymphatic invasion. Tumors with more advanced TNM stages (III and IV) presented downregulation of both genes when compared to those with earlier stages (I and II). Conclusion: The MUTYH and OGG1 genes present downregulation in the more advanced stages of colorectal cancer.

ABSTRACT Background: The effects of topical application of sucralfate (SCF) on the tissue content of MUC-2 protein have not yet been evaluated in experimental models of diversion colitis. Aim: To measure the tissue content of MUC-2 protein in the colonic mucosa diverted from fecal stream submitted to the SCF intervention. Methods: Thirty-six rats underwent derivation of intestinal transit through proximal colostomy and distal mucous fistula. The animals were divided into three groups which were submitted application of enemas with saline, SCF 1 g/kg/day and SCF 2 g/kg/day. Each group was divided into two subgroups, according to euthanasia was done after two or four weeks. The colitis diagnosis was established by histopathological study and the inflammatory intensity was evaluated by previously validated scale. The MUC-2 protein was identified by immunohistochemistry and the tissue content was measured computerized morphometry). Results: The application of enemas with SCF in the concentration of 2 g/kg/day reduced inflammatory score of the segments that were diverted from fecal stream. The content of MUC-2 in diverted colon of the animals submitted to the intervention with SCF, independently of intervention period and the used concentration, was significantly greater than animals submitted to the application of enemas containing saline (p< 0.01). The content of MUC-2 after the intervention with SCF in the concentration of 2 g/kg/day was significantly higher when compared to the animals submitted to the application containing SCF at concentration of 1.0 g/kg/day (p<0.01). The tissue content of MUC-2 reached the highest values after intervention with SCF in the concentration of 2 g/kg/day for four weeks (p<0.01). Conclusion: The preventive application of enemas containing SCF reduces the inflammatory score and avoids the reduction of tissue content of MUC-2, suggesting that the substance is a valid therapeutic strategy to preserve the mucus layer that covers the intestinal epithelium.

ABSTRACT Background: With a prevalence of 0.4-3.5%, subepithelial lesions of the upper digestive tract are discovered during endoscopic procedures. Treatment depends on etiological and pathophysiological information, ability to diagnose and the different technical resources available. Aim: To demonstrate the effectiveness of a surgical technique that combines endoscopy and videolaparoscopy in the transgastric resection of subepithelial juxtacardic lesions. Method: The patients were assisted with a technical combination between endoscopy and laparoscopy. After diagnosis of subepithelial tumor, intraoperative endoscopy was performed after pneumoperitoneum and placement of laparoscopic tweezers. Through endoscopy, the following steps were performed: demarcation of surgical margins, visualization of the intragastric image for the laparoscopic procedure and removal of the surgical specimen. By laparoscopy the following steps were performed: intragastric intra-abdominal access, resection of the part and closure of the gaps. Results: This technique was applied in two cases in order to evaluate its initial results. There were two videolaparoendoscopic resections of juxtacardiac gastric tumors of the posterior wall. Both had their endoscopic diagnosis confirmed. After laparoendoscopic and tomographic and/or ecoendoscopic diagnostic complementation and preoperative performance, the laparoendoscopic procedure was indicated. The patients had a good recovery, with a short hospitalization time and no complications. Conclusion: The combined use of videolaparoscopy and endoscopy is a safe and effective technique for transgastric resection of juxtacardiac subepithelial lesions. It may be important for definitive diagnosis of the tumor.

Published: August 2017

ABSTRACT Background: The isolate resection of the uncinate process of the pancreas is a rarely described procedure but is an adequate surgery to treat benign and low grade malignancies of the uncinate process of the pancreas. Aim: To detail laparoscopic uncinatectomy technique and present the initial results. Method: Patient is placed in supine position with the surgeon between legs. Three 5-mm, one 10-mm and one 12-mm trocars were used to perform the isolated resection of the uncinate process of the pancreas. Parenchymal transection is performed with harmonic scalpel. A hemostatic absorbable tissue is deployed over the area previously occupied by the uncinate process. A Waterman drain is placed. Result: This procedure was applied to an asymptomatic 62-year-old male with biopsy proven low grade neuroendocrine tumor of the pancreatic uncinate process. A laparoscopic pancreaticoduodenectomy was proposed. During the initial surgical evaluation, intraoperative sonography was performed and disclosed that the lesion was a few millimeters away from the Wirsung. The option was to perform a laparoscopic uncinatectomy. Postoperative period until full recovery was swift and uneventful. Conclusion: Laparoscopic uncinatectomy is a safe and efficient procedure when performed by surgical teams with large experience in minimally invasive biliopancreatic procedures.

ABSTRACT Introduction: Several factors have made hepatectomy an increasingly safe surgery and new drugs allowed surgical treatment for patients who initially were not candidates for resection. Lesions often require resection, which can be performed by open, laparoscopic, or robotic assisted hepatectomy. Aim: Compare the surgical techniques in open, laparoscopic, and robotic assisted hepatectomy for resection of liver tumors. Methods: Literature review based on scientific papers published on Lilacs/Pubmed/Scielo in the last 17 years regarding the indications of these techniques for liver tumor resections and on papers comparing such techniques. Results: The comparative study shows the benefits of laparoscopic surgery over open surgery, such as smaller incisions, less postoperative pain, shorter recovery time, smaller immune and metabolic response, and quicker restoration of oral ingestion as well as lower morbidity rates. However, the need for a specialized surgical team and the reduction in handling area still remain as disadvantages in the laparoscopic technique. It is yet not clear whether robotic assistance presents considerable benefits over the laparoscopic technique considering that high acquisition and maintenance costs are limiting factors. Conclusion: Despite all challenges, laparoscopic hepatectomy presents many benefits over open surgery. The robotic assisted technique is still in evolution as many centers in the world perform hepatic resections with the platforms but only after a thorough patient selection. Thus, laparoscopy stands as the best option, unless there is some contraindication to the procedure.

Published: August 2017

Abstract The aim of this study was to find the role of TLR2 signaling pathway in reducing osteoclast activity and promoting osteoblast growth by inducing a combination of Aloe vera and cancellous bovine xenograft (XCB) into dental extraction socket. Forty-eight Cavia cobayas were used. They were divided into eight groups (n=6). For control group, their mandibular incisors were extracted and filled with PEG. For treatment groups, they were extracted and filled with XCB, Aloe vera and the combination of Aloe vera and XCB. The first four groups were sacrificed after 7 days and the other groups after 30 days. Immunohistochemistry and histopathology examination were conducted to examine TLR2, TNFa, OPG, collagen-1, and the osteoblast and osteoclast expressions. The expressions of TLR2, OPG and Collagen-1, as well as the number of osteoblast were increased. Meanwhile, the expressions of TNFa and osteoclast were decreased. The study finding was that TLR2 signaling pathway influenced alveolar bone osteogenesis process by reducing osteoclast activity and stimulating osteoblast growth induced by the combination of Aloe vera and XCB.

Published: August 2017

Abstract Sjögren’s syndrome (SS) is a systemic chronic autoimmune disorder affecting the lacrimal and salivary glands. SS may manifest as primary SS (pSS) or secondary SS (sSS), the latter occurring in the context of another autoimmune disorder. In both cases, the dry eyes and mouth affect the patient’s quality of life. Late complications may include blindness, dental tissue destruction, oral candidiasis and lymphoma. This paper reports two cases of SS, each of them presenting unusual oral nodular lesion diagnosed as relapsed MALT lymphoma and mucocele. The importance of the diagnosis, treatment and management of the oral lesions by a dentist during the care of SS patients is emphasized, as the oral manifestations of SS may compromise the patient’s quality of life.

Published: August 2017

Abstract The aim of this study was to evaluate the influence of an extended use of desensitizing toothpastes (DTs) on dentin bonding, microhardness and roughness. One hundred and twenty bovine incisor teeth were randomly divided into four groups: G1, distilled water (WATER); G2, Colgate Total 12 (CT12); G3, Colgate Sensitive Pro-Relief (CSPR); and G4, Sensodyne Repair ?αμπ; Protect (SRP). Dentin surfaces were etched with 17% EDTA and 2 years of simulated tooth brushing (20,000 cycles) was performed on their surfaces. Knoop microhardness, surface roughness and scanning electron microscopy (SEM) were performed before and after the simulated tooth brushing. For microshear bonding test, a 2-step self-etching adhesive system (Clearfil SE Bond) was used and 0.8 mm diameter composite resin (Filtek Z350 XT) cylinders were built. Microshear test was performed with an orthodontic wire and with a crosshead speed of 0.5 mm/min. The data were analyzed for: 1) bond strength (one-way ANOVA), 2) microhardness intra-group (Student’s test) and inter-group (one-way ANOVA/Tukey’s test) comparisons, 3) roughness intra-group (Student’s test/Wilcoxon’s test) and inter-group (Kruskal-Wallis/Student-Newman-Keuls test) comparisons. The extended use of both dentifrices (conventional and for sensitive teeth) did not affect the bond strength and produced a significant increase in microhardness and roughness of the dentin, except for the microhardness of the SRP group. The simulated tooth brushing technique with water produced an increase in roughness, without reducing significantly the dentin microhardness.

Published: August 2017

Abstract This study investigated the in vitro performance of the commercial bis-acryl composite resins Systemp C&B II (SYS, Ivoclar Vivadent), Protemp 4 (PT4, 3M ESPE), Structur 2C (ST2, Voco) and ProviPlast (PVP, Biodinamica). Characterization involved optical (color stability, translucency parameter, fluorescence), surface (roughness, morphology and elemental composition), physical-chemical (viscosity, polymerization kinetics) and mechanical analyses (Poisson ratio, biaxial flexural strength, flexural modulus). Most tests were carried out after 24 h, but optical and mechanical analyses were carried out after storage in water at 37 °C for 1, 15, and 30 days. Data were statistically analyzed (a=0.05). Most results were material dependent. SYS and PT4 showed stability in color and translucency over time. All materials had similar or higher fluorescence than human enamel. SC2 and PVP showed rougher surfaces than the other bis-acryl composites. Smaller filler particles were observed on the surface of PT4 and PVP compared with the coarser particles from ST2 and SYS. Viscosity readings indicated a thixotropic behavior for all tested materials. SYS had the lowest and PT4 the highest degree of C=C conversion after 10 min. In the polymerization kinetics, PT4 had the highest maximum polymerization rate and reached earlier the transition between polymerization autoacceleration and autodeceleration. PT4 and SYS had significantly higher flexural strength and modulus than ST2 and PVP for most storage times. Results for Poisson ratio varied between materials. Longer storage periods were generally associated with higher frequency of catastrophic failures in the flexural tests. In conclusion, the performance of bis-acryl composite resins varied largely among materials.

Abstract The influence of root canal filling techniques on the penetration of AH Plus into dentinal tubules was evaluated using confocal laser scanning microscopy (CLSM) and the impact on the bond strength of the filling material on the root dentin was evaluated using the push-out test. Roots of the maxillary central incisors (n=40) were prepared with ProTaper Universal and assigned to four groups: lateral condensation, vertical compaction, modified Tagger hybrid and single cone. After root canal filling with gutta-percha and AH Plus, along with the addition of 0.01% fluorescein, the roots were cut into 2-mm slices. CLSM was performed on the first slice of each root third, followed by the push-out test. The second slice was analyzed under SEM. ANOVA demonstrated a statistically significant difference between the root canal filling techniques and the root thirds (p<0.05). For percent penetration, Tukey’s test showed that the vertical compaction (91.77±13.51), lateral condensation (89.18±10.91) and modified Tagger hybrid (87.53±15.42) presented the highest values, which significantly differed (p<0.05) from those of the single cone (78.19±22.46). For bond strength (MPa), lateral condensation (3.42±0.54) and vertical compaction (3.47±0.53) had the highest values (p<0.05), while the modified Tagger hybrid (2.19±0.41) and single cone (0.54±0.21) had the lowest. In conclusion, the lateral condensation, vertical compaction and Modified Tagger’s hybrid techniques resulted in greater penetration and bond strength to the intra-radicular dentin.

Published: August 2017

ABSTRACT: The objective of this study was to evaluate, through partial correlation analysis, the degree of association between herbage accumulation and morphogenetic traits of ‘Tanzania’ grass (Panicum maximum Jacq.) defoliated with 95% of light interception and fertilized with nitrogen, under different planting densities. The experiment was carried out in a randomized complete design with 12 treatments and two replicates, in a 4 × 3 factorial arrangement consisting of four nitrogen rates (0, 80, 160, and 320kg ha-1 Yr-1) and three planting densities (9, 25, and 49 plants m-2). Harvests were performed at 25cm above the soil, when the plots intercepted 95% of the incident light. The simple correlation coefficients between herbage accumulation and leaf and stem elongation rates and leaf appearance rate were high and positive. Correlation between herbage accumulation and leaf lifespan; however, was high and negative. The study of partial correlation coefficients revealed considerable changes in the correlation structure, whereby the association with stem elongation had a negative value statistically equal to zero, indicating no relationship between these variables. A similar result was observed for the correlations between herbage accumulation and leaf appearance and leaf lifespan. The partial correlation between accumulation and leaf elongation was different from zero and positive indicating a strong association. In Guinea grass cv. ‘Tanzania’ canopies defoliated at 95% light interception, leaf elongation is the morphogenetic variable with the highest strength of association with herbage accumulation.

Resumo Anastomoses vasculares são procedimentos comuns realizados por grande parte dos cirurgiões e cujo treinamento ocorre principalmente em seres humanos, contrariando os princípios éticos vigentes. Esse fato se deve, sobretudo, à carência e ao alto custo relacionados aos atuais modelos de treinamento. Assim, este estudo visa avaliar a viabilidade de três vegetais para a realização de anastomoses vasculares. Foram utilizadas cinco unidades de cebolinha, vagem e feijão-verde. Em cada uma tentou-se realizar uma anastomose término-terminal. Conseguiu-se a realização da anastomose apenas na vagem e no feijão-verde. Contudo, por apresentar uma menor espessura, o feijão-verde assemelhou-se mais aos vasos humanos.

RESUMO: Porcine circovirus 2 (PCV2) está associado a vários sinais clínicos que são designados coletivamente como Circovirose e tem grande impacto na suinocultura. O isolamento viral é classicamente realizado em células da linhagem PK-15, contudo outras células têm sido testadas. Apesar dos avanços nos estudos com PCV2, o isolamento ainda é um desafio. Diante da dificuldade de manutenção dessas linhagens celulares comumente utilizadas associadas à necessidade do uso de substâncias tóxicas para o isolamento de PCV2, os objetivos do presente trabalho foram descrever o primeiro isolamento de Porcine circovirus 2b em linhagens de células de macrófago (J744) e verificar a taxa de mutação nesse sistema. Uma amostra de pulmão foi submetida ao sequenciamento e agrupada ao genótipo PCV2b. Essa amostra foi utilizada para inocular uma garrafa de J744 (com 30% de confluência em meio RPMI com 10% de soro fetal bovino) e submetida a cinco passagens, as quais foram acompanhadas por reação em cadeia da polimerase quantitativa (PCRq). As cargas virais inicial e final foram de 2,90 × 103 e de 4,45 × 108 cópias de DNA/µL para PCV2b, respectivamente. O sequenciamento confirmou o isolamento e descartou o coisolamento de mais de um genótipo. Após cinco passagens, o isolado apresentou identidade de 99,7%, com descrição de cinco mutações pontuais, uma sinônima e quatro não sinônimas, observadas nas regiões do gene cap e rep. Os resultados obtidos demonstram que as células J744 apresentam a susceptibilidade, e a instabilidade do vírus em J744 será importante para a compreensão do vírus.

RESUMO O estudo teve como objetivo avaliar a resistência da madeira de Eucalyptus grandis e Eucalyptus cloeziana submetidas a diferentes condições de umidade a impactos. Para tanto, os corpos de prova foram distribuídos em três condições de umidade (seco, climatizado e saturado). Foram avaliadas as propriedade de resistência a impactos, massa específica e teor de umidade de equilíbrio. Os dados foram interpretados por meio de análise de variância fatorial. Dessa maneira, verificou-se que a madeira de E. cloeziana foi mais resistente a impactos na condição saturada em comparação com as amostras climatizada e seca. Já o E. grandis não apresentou diferença significativa entre as condições de umidade testadas. O E. cloeziana demonstrou maior capacidade de absorver impactos em relação ao E. grandis. Ambas as espécies foram classificadas como pouco resistentes a impactos. Portanto, não é recomendado a utilização das espécies estudadas em locais sujeitos a cargas de choque.

RESUMO A mudança no uso da terra, aliada às práticas de manejo, contribui para as alterações entre as entradas e saídas de carbono do solo. O objetivo deste trabalho foi avaliar a dinâmica do carbono no solo em ecossistemas nativos e plantações florestais de Santa Catarina. O trabalho foi conduzido entre os meses de fevereiro e maio de 2007. As áreas avaliadas foram: Campo Nativo (CN); Floresta Ombrófila Mista (FOM); Reflorestamento de Eucalipto (RE) e Pinus (RP). Foram analisados os estoques de carbono, carbono na biomassa microbiana (CBM); respiração basal do solo (RBS) e quocientes microbiano e metabólico (qMic e qCO2). As maiores concentrações de carbono foram encontradas na FOM e no CN, e os atributos bioquímicos indicam que o CN e a FOM possuem a melhor capacidade de armazenar carbono no solo, entre todos os sistemas de uso da terra analisados. Nos reflorestamentos de Eucalipto e Pinus, os altos índices de RBS, qCO2 e as baixas concentrações de CBM sugerem que esses sistemas de uso da terra perdem mais CO2 para atmosfera do que os ambientes nativos.
Presença e remoção de atrazina, desetilatrazina, desisopropilatrazina e desetilhidroxiatrazina em instalação piloto de ozonização e filtração lenta
Authors: Coelho Edumar Ramos Cabral , Bernardo Luiz Di
Published: August 2017

RESUMO Os agrotóxicos, quando utilizados no meio ambiente, sofrem transformações bióticas e abióticas, gerando subprodutos com toxicidade maior ou semelhante ao agrotóxico de origem. No presente estudo foi investigada a dinâmica da presença de atrazina e seus produtos de degradação clorados, desisopropilatrazina e desetilhidroxiatrazina, na oxidação com ozônio, na filtração lenta em areia e na associação dos dois processos em instalação piloto. Foram estudadas as doses de ozônio de 0,9, 1,6 e 2,8 mg.L-1 para concentração de atrazina no afluente, variando de 30 a 79 µg.L-1. Para dose de ozônio de 2,8 mg.L-1, a concentração de atrazina foi inferior a 2 µg.L-1; no entanto, ocorreu formação de subprodutos em concentração superior a 3 µg.L-1. Na filtração lenta, não ocorreu redução da concentração de atrazina. Quando precedida da ozonização, para dose de 1,6 mg.L-1, a concentração de atrazina foi inferior a 2 µg.L-1 e atendeu ao valor máximo permitido pela Portaria MS 2.914/2011; entretanto, a concentração de subprodutos foi superior a 18 µg.L-1. Para dose de 2,8 mg.L-1, o valor de atrasina no efluente filtrado foi inferior a 0,1 µg.L-1, porém a somatória dos subprodutos clorados foi igual a 3,7 µg.L-1, ocorrendo comprometimento sanitário do efluente filtrado. A avaliação da remoção da atrazina em processos que utilizam a ozonização deve sempre estar associada ao monitoramento dos subprodutos clorados, principalmente o desetilatrazina, considerando que ocorre formação desses em concentração superior à da atrazina, produzindo água para abastecimento com elevado risco sanitário, e esses não constam da Portaria MS 2.914/2011.

RESUMO Os objetivos deste trabalho foram estudar o potencial de descoloração do corante Azul Brilhante de Remazol R (RBBR) por cinco isolados de leveduras identificados como OJU2, SJL6, SF5, SJ10 e SJU5, otimizar as condições de crescimento das leveduras e verificar a toxicidade do produto obtido após a descoloração. Para isso, foram realizados ensaios em batelada variando os seguintes parâmetros: pH (2 a 8), concentração de glicose (0 a 3%), concentração do corante (25 a 100 ppm) e temperatura (20 a 40ºC). As leveduras mostraram capacidade de descolorir o RBBR com eficiência entre 80 e 93%, depois de 24 horas. A melhor condição para descoloração do RBBR ocorreu em pH ácido, 2% de glicose, 25 ppm do corante e 25ºC. Com os ensaios com Artemia salina, foi observado diminuição da toxicidade após tratamento com os isolados SJ10 e SJU5, depois de 120 horas de incubação.

Published: August 2017

In this mixed-methods study, 118 adult adoptees completed an online survey gathering information on (a) reasons for seeking therapy, (b) preferences for therapists, (c) perception of therapists' degree of emphasis on adoption during therapy, and (d) relationship satisfaction with adoptive and birth family members. The participants also completed the Satisfaction With Therapy and Therapist Scale–Revised (STTS-R), Adoptive Identity Questionnaire (AIQ), and Rosenberg Self-Esteem Scale (SES). Findings were that the therapists' adoption competence was the most important factor for adoptees in selecting therapists, adoption-related issues were the most common reason adoptees sought therapy, and adoptees reported being more satisfied with therapy if their therapists placed emphasis on adoption regardless of the amount of attention that was focused on adoption.
Using Clinical Assessment to Enhance Adoption Success
Authors: Murray Kathryn J. , Sullivan Kelly M.
Published: August 2017

There is a growing recognition that adoptive families have unique clinical needs, including the need for postadoption mental health services that are adoption competent, trauma informed, and evidence based. Although underrep-resented in the literature, the assessment process is the gateway to the provision of trauma-informed, adoption-competent services for adoptive families. Based on a thorough review of the literature and clinical experience, the current article provides several specific recommendations for social workers and other mental health clinicians in conducting assessment with adoptive families, including domains to assess; specific strategies for assessing each domain; and guidelines for using the results of the assessment for case conceptualization, treatment planning, and family engagement. Implications for practice are discussed, including recommendations for obtaining training needed for adoption competence.

Background

To improve the management of advanced cancer patients with delirium in an emergency department (ED) setting, we compared outcomes between patients with delirium positively diagnosed by both the Confusion Assessment Method (CAM) and Memorial Delirium Assessment Scale (MDAS), or group A (n = 22); by the MDAS only, or group B (n = 22); and by neither CAM nor MDAS, or group C (n = 199).

Materials and Methods

In an oncologic ED, we assessed 243 randomly selected advanced cancer patients for delirium using the CAM and the MDAS and for presence of advance directives. Outcomes extracted from patients’ medical records included hospital and intensive care unit admission rate and overall survival (OS).

Results

Hospitalization rates were 82%, 77%, and 49% for groups A, B, and C, respectively (p = .0013). Intensive care unit rates were 18%, 14%, and 2% for groups A, B, and C, respectively (p = .0004). Percentages with advance directives were 52%, 27%, and 43% for groups A, B, and C, respectively (p = .2247). Median OS was 1.23 months (95% confidence interval [CI] 0.46–3.55) for group A, 4.70 months (95% CI 0.89–7.85) for group B, and 10.45 months (95% CI 7.46–14.82) for group C. Overall survival did not differ significantly between groups A and B (p = .6392), but OS in group C exceeded those of the other groups (p < .0001 each).

Conclusion

Delirium assessed by either CAM or MDAS was associated with worse survival and more hospitalization in patients with advanced cancer in an oncologic ED. Many advanced cancer patients with delirium in ED lack advance directives. Delirium should be assessed regularly and should trigger discussion of goals of care and advance directives.

Published: August 2017

There is an ever-increasing need to develop artificial skin that can fully mimic the human skin that it replaces. Skin substitutes have been commercialized and are used in cosmetics and wound healing treatment, with mixed results obtained. Apart from artificial skin, electronic skin (e-skin) is also widely researched because it can be customized into wearable devices. E-skin is commonly characterized by its flexibility and ability to accommodate a wide range of sensors in ultrathin films. This paper reviews the current development and technology applied to artificial skin and e-skin. First, the basic layers of the normal human skin are introduced. Then, the current development of artificial skin in cosmetics and grafting applications are mentioned in one section. The latest technology in the fabrication of e-skin and some of its characteristics in different applications are also discussed. The ban on the use of animals for testing cosmetics and its positive effects on the development of alternatives to animal testing in experiments are also explained in this paper. Lastly, the current challenges in skin research and recommendations for future applications of artificial skin as well as e-skin are presented.
