Authors: Mamede Francisco , Almeida António
Published: June 2020

O contributo que este estudo propõe apresentar é o do estabelecimento de um guia para adaptação das atividades do Sistema de Gestão da Qualidade (SGQ) no contexto da crise pandémica por COVID-19. A Gestão da Qualidade é uma vertente essencial na grande maioria dos Serviços de Radiologia e a manutenção de SGQ que promovam a melhoria contínua um requisito obrigatório para todos os que procuram manter as Certificações ou Acreditações conseguidas. O contexto atual da pandemia COVID-19 representa um momento de crise para os Serviços de Radiologia e muitas são as dificuldades com que se deparam os profissionais. Estando o foco de toda a atividade completamente dedicado à resolução dos problemas diários que esta situação cria, muitas das atividades anteriormente planeadas, no âmbito do SGQ, deixam de ser realizadas mas será hora de deixar o SGQ num estado de completa hibernação? As metodologias que constituem a base de toda a atividade no âmbito da gestão da qualidade provaram ter um papel fundamental, quer para ultrapassar crises como no período posterior, de recuperação das mesmas. Uma das principais características de qualquer SGQ deve ser a sua flexibilidade e a capacidade que tem que ter para se adaptar a qualquer situação e conseguir a cada momento promover a melhoria. A resposta proposta tem por base a experiência de dois dos maiores hospitais da região de Lisboa a que aqui se juntou a validação de conceitos por várias referências na área da gestão e, mais especificamente, na gestão de crises.

Published: June 2020

Este estudo constitui uma revisão bibliográfica e tem como objetivo demostrar o valor da imagem médica no diagnóstico de COVID-19, apresentando características imagiológicas particulares da pneumonia sugestivas de infeção pelo novo coronavírus ou outra causa. SARS-CoV-2 é um novo vírus de origem desconhecida que surge na China em dezembro de 2019. O diagnóstico é feito através da técnica laboratorial Reverse Transcription Polymerase Chain Reaction (RT-PCR). Os exames de imagem desempenham um papel fundamental no diagnóstico, monitorização e avaliação da extensão das lesões associadas à pneumonia por COVID-19. A radiografia do tórax apresenta baixa sensibilidade e especificidade no diagnóstico de COVID-19 enquanto que, a tomografia computorizada (TC), apresenta alta sensibilidade na deteção de lesões pulmonares, mas baixa especificidade. Imagiologicamente, esta patologia segue um padrão característico semelhante ao de outras pneumonias virais. No entanto, reconhecendo o valor da imagem médica no diagnóstico de pneumonia por COVID-19, o teste laboratorial RT-PCR continua a ser o mais fidedigno.

Authors: Fernandes Cátia , Cunha João
Published: June 2020

No contexto da pandemia COVID-19, surgiu a necessidade de promoção da contenção de aerossóis gerados pelo utente de Via Verde Acidente Vascular Cerebral (AVC), sujeito a terapêutica endovascular cerebral. Deste modo, fez-se recurso a um suporte em acrílico para suspensão de plástico de contenção de aerossóis. Neste enquadramento, pretende-se contribuir para a segurança dos profissionais de saúde, garantindo a otimização da técnica e proteção radiológica na Angiografia. A utilização pontual do mencionado suporte em acrílico despoletou a análise dos valores relacionados com a exposição radiológica, para além da rejeição da imagem radiológica obtida, por comprometimento da avaliação da circulação periférica. Com a interface do suporte de acrílico, os parâmetros de exposição no que se refere à intensidade de corrente elétrica (I) (mA.s) teve um acréscimo de 32,43 %, o produto dose área (DAP) (Gy.cm²) um aumento de 18,96 % e o Air Kerma (mGy) um acréscimo de 18,32 %. Deste modo, a utilização do referido suporte de acrílico não é recomendada pelo comprometimento da qualidade da imagem radiológica e pelo aumento significativo da exposição radiológica para o Utente e para os profissionais de saúde expostos.

Published: June 2020

Organic contaminants with estrogenic activity have generated increasing concerns in the scientific community since they are capable of triggering adverse effects in the endocrine system of several organisms. 17Î±-ethinylestradiol (EE2), a synthetic estrogen used in oral contraceptives, has been identified as one of the main responsible for causing such changes. Thereby the objective of this study was to generate information on EE2 consumption and estimate its possible impact on the water bodies of Santa Maria Madalena. Firstly, a survey was carried out about EE2 consumption through interviews with 325 women aged 15 to 59 residing in the study area, and then estimated the EE2 release in the water bodies. About 30% of the women interviewed reported using oral contraceptives. The EE2 average daily intake for each woman was 20 Î¼g day-1. Extrapolating this intake to 30% of the population and adopting an excretion rate of 57%, it was calculated a total discharge of 4.8 mg day-1 of this estrogen into the local water bodies. It diluted by the small flow of these streams leads to an estimated environmental concentration of 0.3 ng L-1, which according to ecotoxicological studies is already enough to trigger adverse effects to the aquatic biota.

Published: June 2020

Factors that promote customer loyalty are of great concern to the banking sector because loyalty predicts business success. The purpose of this study is to examine the mediation role of corporate social responsibility on the effect of brand awareness and corporate reputation on customer loyalty. Data was collected through a cross sectional survey from 405 bank customers. Research hypotheses were tested using the structural equation model. The findings show that corporate social responsibility partially mediates the effect of both brand awareness and corporate reputation on customer loyalty. The results indicate that corporate social responsibility plays a vital role within the banking sector as it mediates the effect of brand awareness and corporate reputation on customer loyalty. If banks engage in successful corporate social responsibility practices, brand awareness and corporate reputation are enhanced and this result in improved customer loyalty. By empirically examining corporate social responsibility as a mediator on the effect of brand awareness and corporate reputation on customer loyalty the study seeks to contribute to the scholarly conversation.
A simple classification framework for predicting Alzheimer’s disease from region-based grey matter volume and APOE genotype status
Authors: Ghoreishiamiri Reyhaneh , Little Graham , Brown Matthew R. G. , Greiner Russell
Published: June 2020

Alzheimer’s Disease (AD) is a prevalent neurodegenerative disease currently affecting more than 47 million people in the world. There are now many complex classifiers that can accurately distinguish AD patients from healthy controls, based on the subject’s structural magnetic resonance imaging (MRI) brain scan. Most such automated diagnostic systems are blackboxes: While their predictions are accurate, it is difficult for clinicians to interpret those predictions, due to the large number of features used by the classifier, and/or by the complexity of that classifier. This work demonstrates that an automated learning algorithm can produce a simple classifier that can correctly distinguish AD patients from healthy controls (HC) similar to its more-complex counterparts. Here we buildthis classifier from the data in the Alzheimer’s Disease Neuroimaging Initiative database, using a fairly small set of features, including grey matter volumes of 33 regions of interest derived from structural MRI, as well as the APOE genotype. We first considered three simple base-learners that each produce a classifier that is simple and interpretable. Running our overall learner, involving standard feature selection processes and these simple base-learners, on these features, produced a 7-feature elastic net model, EN7, that achieved accuracy of 89.28% on the test set. Next, we ran the same overall learner using two more-complex base-learners over the same initial dataset. The accuracy of the best model here was 90.47%, which was not statistically different from the performance of our much simpler EN7 model.

Lipoleiomyoma: An incidental finding in a case of uterine serous adenocarcinoma
Authors: Weichsler John G , Starr Shane
Published: June 2020

We present a rare case of a lipoleiomyoma which was discovered incidentally in a hysterectomy specimen of a 74-year old female patient who underwent surgery for a biopsy proven serous adenocarcinoma of the uterus. Lipoleiomyomas represent uncommon, usually benign soft-tissue tumors, generally found in obese menopausal as well as postmenopausal women aged 50 to 70 years. The reported incidence varies from 0.03\% to 0.2\%. The relationship between lipoleiomyomas and gynecologic malignancies has only been reported in a few cases. We report this case of lipoleiomyoma due to its rarity and its association with a serous adenocarcinoma in our patient.

Published: June 2020

Introduction:

Acute patellar tendon ruptures are frequently observed in patients with metabolic comorbidities, and the benchmark treatment is surgical repair. It is desirable not to harm an already fragile biologic environment with sutures and hardware. We aimed to compare the mechanical requirements of an isolated, flexible, high-strength nonabsorbable transosseous suture frame with that of the Krackow suture technique.

Methods:

A total of 12 cadaveric pieces were randomized into two groups: the isolated flexible frame group (n = 6) and the standard Krackow fixation group (n = 6). A traumatic rupture of the patellar tendon was performed, and a transosseous displacement sensor was installed on a validated biomechanical system. Gap formation was measured during 50 cycles of flexion and extension with traction on the quadriceps (250 N). Subsequently, specimens underwent progressive loading in a fixed flexion position until failure occurred. The data were analyzed using nonparametric statistical tools with a significance level of 5%.

Results:

The isolated frame group had a smaller gap formation (1.7 mm) than the Krackow group (3.4 mm; P = 0.01). No significant difference existed in the median failure end points of the two groups (676 and 530 N, respectively; P = 0.11).

Discussion:

Patellar tendon repair using an isolated, transosseous, flexible, suture frame outperformed using the traditional Krakow repair technique in gap formation. Further studies are needed to determine if this will result in better functional outcomes or fewer clinical failures.

Level of Evidence:

Level IV, experimental case series

Geen verhaalsrecht werkgever voor afgedragen pensioenpremie

Als een werknemer arbeidsongeschikt raakt, is de werkgever op grond van artikel 7:629 lid 1 BW, en vaak ook op grond van de geldende arbeidsovereenkomst, verplicht om het loon in ieder geval gedurende twee jaar (deels) door te betalen aan de arbeidsongeschikte werknemer. Deze kosten kunnen behoorlijk oplopen, maar de werkgever hoeft deze kosten niet altijd geheel zelf te dragen. In de gevallen waarin een derde aansprakelijk is voor de arbeidsongeschiktheid van de werknemer, kan de werkgever deze loonschade namelijk op grond van artikel 6:107a lid 2 BW op deze aansprakelijke derde verhalen.

New Sales and Contract Law in Argentina and France: Models for Reform Inspired by the CISG and the PICC?

The Argentine and the French civil codes have recently undergone substantial modifications to their contract law provisions. These novel statutes could serve as models for future B2B contract law reforms in Latin American jurisdictions and beyond, as former Argentine and French laws have done in the past. The authors offer a contribution that paves the way in that direction with a systematic comparative analysis. As a starting point, this article unveils the influence that the modern unified laws on contracts (UNIDROIT Principles on International Commercial Contracts (PICC) and United Nations Convention on Contracts for the International Sale of Goods of 1980 (CISG)) have in Argentina’s and France’s new contract law. It also highlights the most obvious similarities and differences in both sets of rules. This contribution goes beyond simple tertium comparisons; the authors analyse which of the two laws offers better, or more effective, rules to achieve the desired contract law functions in various matters. Readers are provided with the best rule or solution to address the problem in question and, as the authors hope, they should conclude that both models provide for a range of complementary solutions for modern contract law reforms.

Background: Increasing in emergency department need to critical care, the number of intensive care unit bed worldwide is inadequate to meet these applies. Objectives: The aim of this study was to investigate the effect of waiting for admission to the Intensive Care Unit (ICU) in the Emergency Department (ED) on the length of stay in the ICU and the mortality of critically ill patients. Methods: This retrospective cohort study carried out between January 2012 - 2019 patients admitted to the ICU of a training and research hospital. The data of 1297 adult patients were obtained by searching the Clinical Decision Support System. Results: The data of the patients were evaluated in two groups as those considered to be delayed and non-delayed. It was determined that the delay of two hours increased the risk of mortality 1.5 times. Hazard Ratios (HR) was 1.548 (1.077 - 2.224). Patients whose ICU admission was delayed by 5 - 6 hours were found to have the highest risk in terms of mortality (HR = 2.291 [1.503 - 3.493]). A statistically significant difference was found in the ICU mortality, 28-day and, 90-day mortality between the two groups. ICU mortality for all patients’ general was 25.2% (327/1297). This rate was 11.4% (55/481) in the non-delayed group and 33.3% (272/816) in the delayed group (P < 0.001). The 28-day mortality rate for all patients’ general was 26.9% (349/1297). This rate was found to be 13.5% (65/481) in the non-delayed group and 34.8% (284/816) in the delayed group (P < 0.001). The 90-day mortality for all patients’ general was 28.4% (368/1297). This rate was 14.1% (68/481) in the non-delayed group and 36.8% (300/816) in the delayed group (P < 0.001). Conclusions: Prolonged stay in the ED before admission to the ICU is associated with worse consequences, and increased mortality.

Intermediate snail host of Schistosoma species are known to exist and constitute public health problems in Imo state. Effects on this study were devoted to evaluate the ecology and distribution of the snail hosts of Schistosoma species at the water bodies of Ihitte Uboma local Government area and this was researched during the months of June and September, 2015. A total of 600 pulmonate or lunged snails were collected using scoop net technique from different water bodies in five villages, out of these, 345 (57.5%) were dissected and screened for cercariae of human Schistosomes 67 (19.4%) tested positive. The snail infected were Bulinus  species 55 (82.1%) and Biomphalaria Pfeifferi (17.9%), out of the Bulinus species, Bulinus globosus recorded the widest ecological range, highest  distribution and infection rate of 44.8% followed by Bulinus truncatus (22.4%). The other two genera Lymnaea spp and Melanoides spp encountered in the study did not test positive for cercariae. Environmental modifications such as water resources development schemes in the area are some of the ecological and epidemiological risk factor promoting the spread of the snails. Statistically, presence of urinary and intestinal Schistosomiasis becomes indicated in Ihitte Uboma L.G.A. Regular and timing mollusciciding, malacological and public health education are therefore recommended and imperative.

High strength, high hardness and very tough engineering material derived from geologically occurring minerals and processed into a tool that rubs or wears off by friction is regarded as an abrasive. Abrasives are produced in different forms and shapes and they afford good opportunities for precision scraping away or machining. In this empirical paper, effort is made in establishing a case for the production of abrasive tools that are formulated with silicon carbide and aluminium oxide as catalytic raw materials. These are locally found in the researchers’ locality a place that has many geological deposits of solid minerals. At each of Ozizza, Ndibe, Kpoghirikpo and Unwana beaches, eleven samples of sand were collected at random locations from the Cross River that is flowing through Ozizza down to Unwana for physical and geochemical investigation to determine its suitability for abrasive making. Sand at the four locations were subjected to physical and geochemical investigation. Generally, the sand was physically characterized by bright colours of white, brown and yellow. Some samples at some locations contained dark specks of organic matter. From the distribution, the sand is generally of medium grade size as shown by the Scanning Electron Microscopy (SEM). Geochemically by X-ray fluorescence (XRF) analysis, the oxide contents are: SiO2 (91.73%), CaO (0.045%), Al2O3 (4.24%), Fe2O3 (1.36%), TiO2 (0.21%), K2O (0.86%). The silica content (91.73%) of the sand is well above the industrial specification of 80% for sanitary ware making and suitable for the silica brick industry, for road dressing mixed with special asphalt.

Aim: The study was carried out to isolate and identify Aspergillus species from commercial birds with suspected aspergillosis in the poultry farms within Ado Ekiti metropolis Nigeria. 

Place and Period of Study: The study was carried out in the Department of Microbiology, Faculty of Science, Ekiti State University Ado Ekiti, Nigeria in August 2016.

Methodology: A total of 35 sick/suspected birds were collected randomly from three poultry farms. At Ago-Aduloju poultry farms, 15 samples were randomly collected from 1000 birds while at Ekiti State University poultry farms, 10 samples were randomly collected from 500 birds. At Federal Polytechnic Ado Ekiti poultry farms, 10 samples were randomly collected from 700 birds. The bird’s selection was on the basis of clinical signs and symptoms such as difficulty in breathing, weight loss, drooping of wings and exercise intolerance. Swab samples were collected from each suspected/sick bird for mycological culture and molecular characterization of the isolates from each bird was carried out. The isolates were identified based on the color of the culture on Potato Dextrose Agar and microscopic examination. Molecular identification was done using 23S Ribosomal RNA Gene and Partial Sequence.

Results: Six fungal strains that showed similar morphological and cultural characteristics of Aspergillus species were isolated. The isolates were coded ASP 1, ASP 2, ASP 3, ASP 4, ASP 5, and ASP 6. The identified organisms were; Aspergillus fumigatus qH 107 (ASP 1), Aspergillus fumigatus qH 107 (ASP 2), Aspergillus flavus M09 (ASP 3), Aspergillus flavus UOMS6 (ASP 4), Aspergillus fumigatus qH 107 (ASP 5), Aspergillus flavus qH 107 (ASP 6).

Conclusion: It is evident that Aspergillus species were predominant in poultry farms selected in this study. Necessary precaution should be put in place to prevent the spread of aspergillosis. Poultry farmers are advised to avoid damp environments, moldy feeds, dry and dusty litters. Adequate ventilation should always be provided in poultry farms to prevent Aspergillosis.

Aims: This study presents baseline data on the In-vitro and In-vivo evaluation of anti-trypanosomal activity of Carica papaya seed extracts and fractions in Albino Wister rats.

Study Design: Mention the design of the study here.

Place and Duration of Study Sample: Department of Biochemistry, Modibbo Adama University of Technology, Yola, between June 2009 and July 2010.

Methodology: 56 Wister rats of both sexes were randomly divided into 8 groups (I – VIII) of 7 rats each were used for this study. Four concentrations (100, 200, 400 and 800 mg/kg) of different extracts of seed carica papaya were screened for trypanocidal activity against Trypanosoma brucei In vitro and In vivo. The effect of the extracts was evaluated for trypanocidal activity in rats infected and not infected with the parasite. Administration of the extract and the drugs was orally daily for 5 consecutive days from day 7 of post infection. Level of parasitemia and body weight was taken daily for 21 days.

Results: The extracts inhibited parasite motility and totally eliminated the organisms at the concentrations used In vitro. The extract also showed promising in vivo trypanocidal activity. The observed In vitro and In vivo trypanocidal activities may be due to the presence of bioactive compounds present in the extracts as seen in this study. The extract also improved the observed decreases in haematological parameters of the treated rats, which may be due to their ability to decrease parasite load. The LD50 was estimated to be ≥2,000 mg/Kg (v/v) for acute oral toxicity test (because all the rats survived at the end of the 14-day observation period). This is an indication of very low toxicity, implying that the extract could be administered with some degree of safety. A significant decreased (p<0.05) were observed in weight of rats at 100 mg/kg, 200 mg/kg 400 mg/kg 800 mg/kg negative control and prophylactic at four to eight days of infections, while significantly increased (p<0.05) were observed in weight of rats for berenil control and normal control.

Conclusion: The decrease in weight of rats could be as a result of loss of appetite due to severe fever and also the trypanosome.

Existence of Career Decision Making Difficulty (CDD) is lightly addressed in the career planning and career management body of knowledge. The purpose of this explanatory study was to test the prevalence and the nature of the CDD specifically among the Sri Lankan undergraduates. An explanatory study was carried out with the data of filed survey of 108 valid responses those represent the Sri Lankan universities. The instrument of three facets of CDD [1] was used as the principle measure of responses. Results showed the prevalence of significant level of CDD among undergraduates of Sri Lanka universities. The lack of readiness appears prior to the career decision making process and the great level of CDD is supported by lack of readiness. Lack of information and inconsistent information are too significantly contributing CDD among undergraduates during the career decision making process. Lack of readiness of Sri Lankan undergraduates is mainly due to their dysfunctional belief and general indecisiveness rather than lack of motivation.
Review on the Root, Stem and Leaf Initiations in Plants

Published: June 2020

The root and shoot apical meristem serve as sources of pluripotent cells and provide new cells for repetitive organ initiation, they are the major meristematic regions on which plant development take place. New meristems are incessantly formed as plants produce new branches or lateral roots thus making the understanding of meristem function central to how plants can establish different growth types, ranging from tiny herbs to huge trees. The sizes and numbers of meristems that are initiated during advanced development control the size and number of fruits and the generation of seeds. The development of a lateral root from a limited number of cells requires compactly coordinated asymmetric cell divisions to generate cell diversity and tissue patterns which characteristically involves the specification of founder cells, followed by a number of cellular changes until the cells divide and give rise to unequally sized daughter cells. Leaf development exemplifies the dynamic nature and flexibility of plant development in response to internal and external cues which is evidenced in the fact that two plants, even if genetically identical, do not look the same, two leaves on the same plant are different, and the final shape of a leaf is not predetermined when it starts to form. Leaves evolved from lateral branches following the acquisition of determinate growth and a flat structure, thus the specification of organ initiation involves a complex network of genetic, hormonal and mechanical factors which has been discussed in this review.
Changing Lessons: The Kumasi School of “Art and Crafts” in a Scottish Regime (1952-1962)

Published: June 2020

This paper fills a gap in the historiography of Ghana’s modern art curricula. Between 1952 and the turn of the 20th century, the Kumasi College of Art (KNUST), operated two successive curriculum models, the “Art as Teacher Training” model and the “Art as Industrial, Commercial and Professional Enterprise model”. “The Art as Teacher Training” model, the emphasis of this paper, was administered by a team of British and African staff of “Art and Crafts” persuasion. The first decade (1952-1962), led by a Scottish regime of Glasgow Style extraction, upgraded an extant Specialist Art and Crafts Course to a Diploma in Fine Art programme. The study shows how the changing lessons of the Gold Coast and Ghana “School of Art and Crafts” curriculum in Kumasi intersected with the changing fortunes of metropolitan British art institutions such as the Glasgow School of Art (GSA), the Slade, and Royal College of Art (RCA). The paper argues that the persistence of the “Art and Crafts” and “teacher training” ethos in the Scottish regime could have heralded a move towards an emancipated curriculum indifferent to media specialization and antithetical to media-genre-skill elitism. The author notes that the blurred boundaries between “art” and “craft” or “art” and “the everyday” seem prescient for its time, yet, the curriculum’s vocationalist and instrumentalist framework stood in the way of producing independent artists of note.

A field investigation was conducted to evaluate the effect of moisture conservation practices [flat bed sowing, ridge and furrow, broad bed and furrow (BBF) and poly mulch on BBF] and integrated nutrient management treatments [Farmer’s practice, 100% recommended dose of fertilizers (RDF) of 150:60:60 NPK kg ha-1, 125% RDF, 100% RDF along with 25% N through Farm Yard Manure (FYM) or press mud] and their combined effect on weed dynamics of Bt cotton at College Farm, Professor Jayashankar Telangana State Agricultural University (PJTSAU), Telangana, India. The experiment was laid out in strip-plot design and replicated thrice. Pooled data of the two years (2015 and 2016) indicated that poly mulch on broad bed (M4) registered significantly lower weed density and dry weight at 30 days after sowing (DAS) and it was followed by broad bed and furrow (M3) which was at par with flat bed (M1) and ridge and furrow (M2) methods. Among nutrient management practices, lower weed density was recorded with the application of 100% RDF (S2) followed by 125% RDF (S3) and 100% RDF (S5) along with pressmud equivalent to 25% RDN (S5). However, the interaction effect on weed density and drymatter was found to be non-significant at 30 DAS. Contrary to this, at 60 and 90 DAS, the interaction was found to be significant. At 60 DAS, poly mulch on broad bed (M4S2) along with 100% RDF and poly mulch on broad bed (M4S3) along with 125% RDF recorded lower weed density over other treatment combinations. At 90 DAS also similar results were observed with respect to weed density. However, lower weed dry weight was observed with poly mulch on broad bed (M4S3) along with 125% RDF.

Vigour reduction through dwarf rootstocks is an essential element of high density planting systems. Cashew is a vigorous evergreen perennial woody plant that is traditionally cultivated in a low density planting system. The present investigations were carried out at ICAR-Directorate of Cashew Research, Puttur, Karnataka, India to find out the effects of vigour controlling rootstocks on vegetative growth and yield of cashew cultivars. The experiment was laid out in a randomized block design with twelve combinations of scion/rootstock with three replications. Different growth habits of four cashew varieties scions (Ullal-3, VRI-3, NRCSel-2 and Vengurla-4) grafted on two dwarfing rootstocks (NRC-492 and Taliparamba-1) and one vigorous rootstock (Vengurla-4) were studied. The results revealed that various stionic combinations varied to growth and yield parameters. Significant interactions indicated that Taliparamba-1 (dwarfing rootstock) with VRI-3 consistently reduced the growth and vigour based on their lower mean tree height, plant volume, TCSA and canopy spread. Stionic combination of VRI-3/ NRC 492 recorded the highest cumulative nut yield of 16.77 kg/ tree (5 seasons of cropping). Based on observation on growth and yield of various stionic combinations revealed that NRC 492 could be used as a rootstock to induce semi dwarfism with a higher nut yield.
