Published: April 2018

Summary Objective: This study describes the summary scores of the Short Form-12 (SF-12) questionnaire, according to socio-demographic factors obtained in a probabilistic and representative sample of the Brazilian urban population. Method: Five thousand (5,000) individuals, over the age of 15, were assessed in 16 capital cities, in the five regions of the country. The selection of households was random. Face-to-face approach was applied in the household interviews. The SF-12 questionnaire was used to assess quality of life. Demographic and socioeconomic characteristics were also evaluated: gender, age, marital status, skin color, region of the country and use of the public health service. Results: The mean value (SD) of the SF-12 for the entire population was 49.3 (8.7) for the physical component (PCS-12) and 52.7 (9.7) for the mental component (MCS-12). Statistical differences were found for gender (PCS-12 and MCS-12), age (PCS-12) and working status (PCS-12 and MCS-12). Women, elderly, widowed and unemployed individuals, those with lower income and with complaints in the last seven days showed lower mean values (PCS-12 and MCS-12). Conclusion: From this point forward, we can provide the basis for comparisons with future research that use the SF-12 for quality of life assessment in Brazil. The Brazilian population has a lower degree of quality of life related do the physical component, and the SF-12 is a useful and discriminative instrument for assessing quality of life in different socio-demographic groups.

Conclusion: Although there are differences between them, it was possible to establish a minimum core of conducts that may be useful in the daily practice of the physician.
Expansão dos cursos públicos de Serviço Social entre os anos de 2003 e 2016: desafios para a formação profissional
Authors: Pereira Larissa Dahmer
Published: April 2018

Resumo O artigo analisa dados referentes aos cursos públicos de Serviço Social, criados entre 2003 e 2016, coletados no sistema eMEC. Os dados referem-se aos períodos e subperíodos de criação, categoria administrativa, organização acadêmica, região e localização geográfica. Como resultados, constata-se que o período em análise (2003 a 2016) criou mais da metade dos cursos públicos de Serviço Social, com significativo impacto para a formação na área pública. Contudo, no mesmo período, o setor privado também cresceu expressivamente, com forte mercantilização do ensino superior brasileiro e o uso significativo da modalidade de Ensino a Distância (EaD) como estratégia de expansão lucrativa. Ao mesmo tempo, observa-se, com base em diversos estudiosos do campo da Educação, uma expansão precarizada do setor público. Assim, indica-se a necessidade de pesquisas que conheçam a formação em tais cursos, problematizando seus limites e potencialidades, no intuito de fortalecer a formação pública, de qualidade, universal, gratuita e laica.
Observações sobre método, teoria política e educação em Antonio Gramsci
Authors: Inacio Adriele Andreia , Almeida Tatiani Maria Garcia de , Schlesener Anita Helena
Published: April 2018

Resumo O político, filósofo e militante Antonio Gramsci trouxe contribuições para a teoria marxista ao considerar os elementos históricos que permeavam a Itália em sua época, ampliando, deste modo, as categorias e conceitos marxistas. Nesse sentido, este ensaio tem por objetivo refletir sobre o método em Gramsci, o qual considera método o conjunto traduzido na concepção de mundo e na teoria do conhecimento. Tal compreensão gramsciana eleva a filosofia das práxis acima do materialismo determinístico e supera o idealismo especulativo que concebe a história apenas abstratamente. Portanto, o método em Gramsci consiste em levar adiante as dimensões da subjetividade da filosofia moderna, porém, voltando-se sempre para a transformação das estruturas, da consciência nunca separada dos condicionamentos sociais e dos conflitos de classes no âmbito do processo histórico. A metodologia deste trabalho consiste em uma pesquisa bibliográfica a partir de autores marxistas que possuem suporte teórico gramsciano.
Assessment of psychosocial factors at work: A systematic review
Authors: VAZQUEZ Ana Claudia Souza , PIANEZOLLA Mauricio , HUTZ Claudio Simon
Published: April 2018

Abstract This paper presents a systematic review of Brazilian and international studies on the assessment of psychosocial factors, published between 2009 and 2015, with emphasis on the analysis of assessment instruments. One of the main interests of this review was to identify, in the published articles, the use of principles of Positive Psychology in the analysis of factors of prevention, promotion and health protection of workers. A total of 5,724 articles were found. Articles that were repeated or not written in Portuguese, English or Spanish were excluded. Thus, after analysis, 410 articles remained. Of these, 69 articles that dealt directly with the evaluation of psychosocial factors at work were selected. Most studies address the pathogenesis of psychosocial factors, but there is increasing number of studies that combine the analyses of pathogenic factors with motivational factors in health promotion and in the study of preserved positive aspects. We found that although the findings indicate an incipient movement concerning some protective factors (social support, creativity, engagement, etc.), there are still few studies in the Positive Psychology approach. We suggest that further studies test integrative theoretical models or stressors and motivational factors to deepen the understanding of the protective factors and positive aspects associated with psychosocial factors at work.

Published: April 2018

Abstract Studies addressing issues related to information processing are necessary to understand some of the explanatory aspects of the changes in the learning process. The objective of the this study was to evaluate memory and intellectual styles in Elementary and Middle school students diagnosed with dyslexia and Attention Deficit Hyperactivity Disorder and in students without learning disabilities. A total of 370 students from public schools were individually evaluated using the Rey Complex Figure Test and the Thinking Styles Inventory – Revised II. The results showed significant differences in the memory condition between students with Attention Deficit Hyperactivity Disorder and those without learning disabilities. Significant differences in the scores of the Thinking Styles Inventory were also found between the three groups evaluated. Memory was negatively correlated with the conservative style. The difference between the groups and the correlation between these instruments pointed to the need for further research to assess these variables in the groups of students with learning disabilities.
Os mortos e feridos na “guerra às drogas”: uma crítica ao paradigma proibicionista
Authors: RYBKA Larissa Nadine , NASCIMENTO Juliana Luporini do , GUZZO Raquel Souza Lobo
Published: April 2018

Resumo A crítica ao proibicionismo, paradigma de política de drogas globalmente hegemônico, tem como ponto de partida a emergência da própria “questão das drogas”, em âmbito internacional, há aproximadamente um século. As motivações, as estratégias e os desdobramentos desse paradigma serão analisados em torno dos dois eixos que o constituem: a medicalização e a criminalização (ambos associados a questões morais profundamente arraigadas nas sociedades que o adotaram. O presente artigo se deterá nas particularidades do processo brasileiro, desde a implantação do proibicionismo, no início do século XX, até a sua configuração atual de “guerra às drogas”, engendrada nos anos 1960. Nessa trajetória, a partir dos anos 1970, vozes dissonantes oriundas de diversos campos de conhecimento e de ação política têm se erguido. A explicitação dos objetivos não declarados da “guerra às drogas” (que a tornam, afinal, vitoriosa) e a construção de políticas públicas alternativas por esses atores têm gerado tensões e fissuras importantes na política de drogas vigente.
Prejudice and discrimination in the everyday life of same-sex couples raising children

Published: April 2018

Abstract The present study investigated the experiences of prejudice and discrimination in the everyday lives of five same-sex couples raising children. Data were collected using a questionnaire and an interview and were analyzed by thematic analysis. Participants attributed meanings to their experiences of being homoparental families: they assumed their social role as they managed to develop their own conjugality and parental projects in the struggle within a social context permeated by the hegemony of heteronormative values. The participants experienced prejudice related to their lifestyle and attained parenthood status, challenging social norms and gender stereotypes. However, it was also found that attitudes of willingness and perseverance in their fight for their rights proved to be protective measures against prejudice and social intolerance. A limited number of studies have examined the prejudice and discrimination towards same-sex families in Brazil; therefore, there is a need for greater visibility and further discussion about this phenomenon.

Authors: ARAÚJO ALANA CRISTINA FERREIRA , MADALÃO JOÃO CARLOS , JAKELAITIS ADRIANO , COSTA ALAN CARLOS , ALMEIDA GABRIEL MARTINS
Published: April 2018

ABSTRACT Some forages release allelopathic substances into the environment, and may prevent consortium with arboreal species in pastures. The objective of this work was to evaluate photosynthetic characteristics of pequizeiro plants (hereafter pequi) influenced by concentrations of residues of the forage species Urocholoa decumbens, Melinis minutiflora and Paspalum notatum. The treatments consisted of pequi cultivation under aerial residues of the three forage species mixed to the substrate in four concentrations (1, 2, 3 and 4% mass/mass), plus an additional treatment (comparative control) with pequi cultivated on the substrate without waste. The following parameters were evaluated: photosynthetic rate, stomatal conductance, transpiration rate, relationship between internal and external CO2 concentration (Ci/Ca), maximum quantum yield, effective quantum yield of FS II, electron transport rate, nonchemical quenching and chlorophyll index, concerning the content of chlorophyll a, b and total in pequi plants at 50 and 100 days after transplanting (DAT), and the relative production of dry matter at 100 DAT. At 50 DAT, the following photosynthetic variables were affected in pequi plants: A, gs, chlorophyll a, chlorophyll b and total chlorophyll when cultivated in the presence of forage residues. At 100 DAT, the following photosynthetic variables were affected in pequi plants: A, Fv/Fm, ETR, NPQ, chlorophyll a, chlorophyll b and total chlorophyll, when cultivated in the presence of forage residues. Pequi plants had reduced relative dry matter yield when grown in the presence of U. decumbens. This variable was also affected when pequi was grown in increasing concentrations of residues of the species U. decumbens, M. minutiflora and P. notatum.

ABSTRACT The objective of this work was to assess the effect of vegetation on the runoff coefficients of a Caatinga dry tropical forest before and after thinning. Thus, an experiment was conducted with evaluations in three hydrological years (2008, 2011 and 2013) in Iguatu, State of Ceará, Brazil. In 2008, the vegetation consisted of a 30-year regenerating Caatinga forest. The vegetation was subjected to thinning in 2009, 2011 and 2013, removing trees with less than 10-cm diameter at breast height. Hydrological responses were evaluated as a function of daily precipitation water depths, based on cumulative frequency distribution, by dividing precipitation events into three classes (CP) (CP≤30, 3050 mm). Significant differences between runoff coefficients before and after vegetation thinning were assessed through the Student's t-test (p<0.01). Before thinning (2008), CP≤30 mm showed the highest runoff coefficient, differing statistically (p<0.01) from the other years. The results of precipitation events of great magnitude (CP>50 mm) indicate that the runoff is greatly dependent on rainfall characteristics and soil moisture conditions. The greater development of herbaceous vegetation due to thinning reduced the surface runoff.

ABSTRACT Cowpea (Vigna unguiculata [L.] Walp.) is one of the most important legumes produced in tropical and subtropical regions throughout the world, especially in the developing countries in Africa, Latin America, and Asia. It is the main source of protein, calories, dietary fiber, minerals, and vitamins for a large segment of the world population. Cowpea is also a potential functional food with a range of bioactive compounds, including phenolic compounds. This legume is grown mainly in the North and Northeast regions of Brazil, but is also consumed in other regions, and is thus important for the farmers who depend on this crop for income. This study identified and quantified phenolic compounds in the cowpea cultivar BRS Xiquexique. Such quantification reveals the functional characteristics of cowpeas, mainly as a source of antioxidants, which will be essential to add value to this food and to expand its forms of consumption. The extracts were analyzed using an HPLC model LC-20AT, equipped with a manual injector. For the HPLC analysis, standard solutions were prepared with pure phenolic acids such as gallic acid, quercetin, caffeic acid, chlorogenic acid, ferulic acid, p-coumaric acid, catechin, and epicatechin. The major phenolic compounds identified were catechin (2.07± 0.329 mg 100 g-1), epicatechin (0.48 ± 0.130 mg 100 g-1), gallic acid (67.19 ± 6.200 mg 100 g-1), ferulic acid (32.07 ± 0.753 mg 100 g-1), and chlorogenic acid (3.08 ± 0.489 mg 100 g-1). We observed that the BRS Xiquexique cultivar contains functional phenolic compounds, especially gallic acid and ferulic acid, demonstrating the antioxidant potential of cowpea.

ABSTRACT The aim of this study was to assess the productive performance of cowpea cultivars with different growth habits as a function of population density in the MATOPIBA region, Brazil. The experiments were carried out in Magalhães de Almeida, MA in the agricultural season 2014/2015. The cultivars BRS Itaim, BRS Tumucumaque, and BRS Pajeú, which present an erect, semi-erect, and semi-prostrate growth habits, respectively, were assessed. For the erect and semi-erect cultivars, a total of 8, 12, 16, 20, 24, and 28 plants m−2 were used whereas for the semi-prostrate cultivar, a total of 2, 6, 10, 14, 18, and 22 plants m−2 were used. The experimental design was a randomized block design with four replications and treatments composed of plant densities. Grain yield and number of pods per area presented a quadratic response to the increased plant density whereas a decreasing linear response was observed for the number of pods per plant. The maximum grain yield of erect, semi-erect, and semi-prostrate cultivars were 1,076 kg ha−1 (19.5 plants m−2), 1,252 kg ha−1 (18.7 plants m−2), and 755 kg ha−1 (14.5 plants m−2), respectively. The number of pods per area was the character that most correlated (P<0.01) with grain yield, regardless of the plant growth habit.

Published: April 2018

ABSTRACT The underground water reserves in the semi-arid region present high salinity levels. However, the scarcity of the resource compels the use of this water for several human activities, including agriculture. The aim of this work was to evaluate the use of brackish water for watercress cultivation (Nasturtium officinale) in a hydroponic NFT system (laminar flow of nutrients) and effects on water consumption, growth, yield and nutrient extraction by the plant. We studied six levels of salinity (0.2; 1.2; 2.2; 3.2; 4.2 and 5.2 dS m-1), in a completely randomized experimental design, with four replicates. Salinity was obtained by the addition of NaCl into the local water supply, being these waters used to prepare the nutrient solution and to replace the evapotranspirated water volume. We noticed a reduction in leaf area, fresh and dry mass of shoot, K content in plant and water consumption of the crop and, increased contents of P, Na, Cl in the plants, with increasing salinity of the solution. The use of brackish water for watercress cultivation in hydroponics is possible as an alternative for producers who have availability of brackish water and restricted possibility of fresh water. A reduction in dry mass of plants was observed with increasing electrical conductivity.

Published: April 2018

ABSTRACT Dormancy in lettuce seeds is a process not yet fully understood. High storage temperatures can cause seed dormancy promoting physiological and enzymatic changes. The goal of this study was to investigate the influence of storage period and environments on the quality and dormancy of different lettuce cultivars. We also investigated the biochemical changes. A completely randomized experimental design was used in a 4x8x3 factorial arrangement to evaluate physiological quality on different storage periods (30, 60, 90 and 120 days) and environments (15, 25 and 35°C) of seeds from eight lettuce cultivars (Everglades, Babá de Verão, Elisa, Luiza, Grand Rapids, Hortência, Salinas 88 and Rubete). The biochemical activity was accessed by tetrazolium test and the activity of the endo-β-mannanase. There occurred physiological and biochemical changes on lettuce seeds under periods and high temperature storage environments. A reduction of seed quality occurred at high storage temperatures mainly when stored during 120 days. The storage period up to six months maintains the viability and vigor of lettuce seeds, when stored at 15°C. Germination is compromised when seeds are stored over 60 days on temperatures over 25°C. Everglades is a tolerant cultivar to germination conditions of 35°C and maintains its quality during storage at 15°C. Temperatures over 25°C induce thermodormancy on lettuce seeds during storage. The tetrazolium test indicates that the seeds were viable; nevertheless, there was no germination at high temperatures. Enzymatic changes occurred in seeds stored at 35°C due to dormancy. There was a decrease in the expression of endo-β-mannanase enzyme being influenced by the environment and storage period. The Everglades cultivar is thermotolerant.

Published: April 2018

This study aimed to identify the trends in the studies conducted on Educational Augmented Reality (AR). 105 articles found in ERIC, EBSCOhost and ScinceDirect databases were reviewed with this purpose in mind. Analyses displayed that the number of educational AR studies has increased over the years. Quantitative methods were mostly preferred in those articles and educational AR was often found to be used in science education (physics, chemistry and biology), engineering education and medical training. The reviewed articles showed that “undergraduate students” were used as samples for most of the time, the most often preferred sample size was between “31-100” and “surveys” were the most utilized data collection tools. While the majority of the articles used marker-based AR as AR type, mobile devices were utilized in many of these articles as the delivery technology. It is believed that the results obtained in this study will light the way for future research.

knowledge regarding learning approaches and learning fields at the core of the
Science Curriculum are increased not because of their working duration because
of their high education level. It was also concluded that science teachers
often considered science curriculum as effective/sufficient in the context of
knowledge category; however they often regarded it as
ineffective/insufficient in the context of skill, sense and
science-technology-society-environment (STSE) categories.

Atopic dermatitis is a chronic relapsing inflammatory skin disease affecting both children and adults. The use of ‘atopic’ in dermatitis describes the scenario where the skin can be demonstrated to react readily to environmental irritants and allergens.A blinded, repeated measures, self-controlled experimental design study with Super Fine Merino Base Layer Garments (SMWBG) intervention worn in 29 Atopic Dermatitis AD patients between the ages of 6 to 25 years was conducted over a 15 week period. Results indicated improvement in AD symptoms and signs. This Human Research Ethics Committee (HREC) approved study was conducted in Brisbane, Australia between July 2014 and October 2015. Our study aim was to look at the use of SMWBG as a sustainable adjunct treatment option for participants with AD. This study assessed the tolerability and potential therapeutic effect of SMWBG (garments worn directly against the skin) in children and young adults with atopic dermatitis (AD). We assessed the severity of AD looking at SCORAD1, EASI2, POEM3 and DSA4.
Stranded Mapping from Long Reads v1
Authors: A Eccles David
Published: April 2018

This protocol demonstrates how to convert raw long reads produced using a strand-specific sequencing protocol (e.g. ONT's strand-switching protocol) into strand-specific mapped reads. The general ides is to use LAST to identify the adapter orientation relative to the genome, and then use that information to split BAM files up and recombine them to create two strand-specific files that are displayable in a genome browser.

Published: April 2018

The paper focuses on the regional experience in approbation and pilot implementation of the professional standard for education psychologists (“Psychologist in Education”) and presents the outcomes of pilot studies of standard implementation carried out in twelve subjects of the Russian Federation in 2015—2017. We describe the stages of informational and analytical support of the approbation rendered in 2017 in the process of implementation of a roadmap developed by the Ministry for Education and Science of the Russian Federation. This roadmap involved a set of research and practice-oriented measures, monitoring studies etc. aimed at testing and implementing the professional standard for educational psychologists. The paper highlights the main problems concerning this new professional standard and provides some recommendations on its effective implementation in the subjects of the Russian Federation within the framework of the existing legislation.
THE EFFECT OF CORRUPTION AND COUNTRY RISK ON FDI INFLOWS: EMPIRICAL EVIDENCE FROM DEVELOPING COUNTRIES
Authors: TÜREDİ Salih
Published: April 2018

The aim of this study
is to empirically analyze the effect of corruption and country risk on foreign
direct investment (FDI) inflows. The study was carried out using the data of 49
developing countries for the 2002–2015 period. Relationships between the
variables were investigated by static and dynamic panel data methods. This
empirical analysis revealed the following general findings: i) a decline in
corruption and country risk positively affects FDI inflows; ii) financial risk,
which is a component of country risk, has no significant effect on FDI inflows,
whereas a fall in the level of economic and political risk accelerates FDI
inflows; iii) FDI inflows are most sensitive to economic risk. Based on these
results, it can be said that developing countries can attract more FDI by
creating a quality institutional structure, effectively fighting corruption,
and creating sound macroeconomic policies that improve the investment climate
and reduce cost, uncertainty, and risk perception.

Authors: Nayak Ashok , S. M. Sajith Babu , Singh Lal Mani
Published: April 2018

Background: Patient suffering from CNS tumours are among the best suited as regards the study of their immunologic status is concerned because these tumours rarely metastasize and general condition of patient is not much affected. Extensive research has been done on immunological response in neoplasms of other organs, but immunology of CNS tumours studied mainly during last five decades. It is now realized that immunologic reactions may be important in the development and growth of the CNS tumours. Although there is evidence that immunotherapy is helpful in control of some solid tumours but adequate knowledge of the immunology of glial tumours to guide the rational treatment is not yet available.  Methods: This study was conducted on 60 cases that included 20 controls and 40 patients of primary intracranial brain tumors admitted to neurosurgical services of University Hospital, Banaras Hindu University, Varanasi during the period of January 1987 to January 1988. Results: The study revealed, medulloblastoma and glioblastoma or anaplastic astrocytoma show more marked suppression of cell mediated immunity than astrocytoma grade +II and other malignant tumour subgroups. In case of humoral immune response, antigen of brain tumours elicit an Ig M response rather IgG response which is commonly elicited in other neoplasia.Conclusions: The results regarding Ig M, and Ig G levels are in agreement with most of the other studies. It appears that antigen of brain tumours elicits an Ig M response rather IgG response which is commonly elicited in other neoplasia.

Authors: Korday Charusheela S. , Sharma Ravindra K. , Malik Sushma
Published: April 2018

Background: Poor child feeding practices and sub-optimal breastfeeding have a detrimental effect on health of children less than 2 years of age. We studied the breastfeeding as well as the complementary feeding practices in the children <2 years of age in our tertiary institute with the help of the WHO2008 document, Indicators for assessing infant and young child feeding (IYCF) practices.Methods: This cross-sectional study was carried out in asymptomatic children (< 2 years), in a tertiary care hospital using a pre-designed, validated WHO questionnaire for information regarding feeding practices.Results: The mean age in hours, for initiation of breastfeeding after birth was 3.92. Amongst the age group of 4-5 months, 72.9% (51/70) babies were exclusively breastfed and 86% (43/50) of infants aged 6–8 months received appropriate solid, semi-solid or soft food. Breastfeeding was continued in majority of the children in 90% in the age group of 12-15 months. Only 13 (7.5%) of 177 breastfed babies and only 4 (8.5%) out of 47 non-breastfed were receiving Minimal Acceptable Diet in the 6-23 months group.Conclusions: Although the results for the breastfeeding and weaning indicators were fairly good, there still exists a lack of knowledge about complimentary feeding practices which need to be drastically improved by appropriate health education and dietary advice.
Maternal haemoglobin and neo-natal haemoglobin status: a hospital based study in Ranchi, Jharkhand, India
Authors: Chaturvedi Priyanka , Chaturvedi Deepak , Dubraj Prita Naz , Chaudhary A. K.
Published: April 2018

Background: Haemoglobin of foetus increases with advancing gestational age. During pregnancy, fetal demand for iron increases maternal daily iron requirement from first trimester to third trimester. Late cord clamping may result in delivery of extra blood as well as iron to newborn. The cause of worry here is that maternal anaemia is a significant cause of direct and indirect morbidity and mortality both for pregnant mother and her foetus/neonate.Methods: To determine maternal and neonatal haemoglobin status we conducted a cross sectional study comprising 217 pregnant women and their children in Ranchi, Jharkhand, India.Results: Mean neonatal haemoglobin in controls was 18.13±1.14 g/dl whereas that in cases was 17.21±1.38 g/dl and the difference was statistically significant. Among the 97 cases 23 mothers had babies with neonatal haemoglobin below 14g/dl. In controls only 17 out of 120 mothers had babies with neonatal haemoglobin below 14g/dl (p value<0.01).Conclusions: Present study demonstrated that the neonatal haemoglobin is lower in anemic mothers and that the decrease appears to be proportional to the degree of anemia.

Published: April 2018

Background: Medical students during their training period to become competent physicians are themselves vulnerable to various stresses which can affect their health and academic performance. The objectives of the study were to study MBBS students perceptions of stress factors affecting their academic performance; to assess the perceived stress in the students; to identify the stress management techniques used by the students.Methods: A cross-sectional was conducted on 169 MBBS students in a private medical college in Navi Mumbai after taking their consent. Data collection was by pretested, pre-coded, semi-structured self-administered questionnaire. Statistical analysis was done by SPSS Version 20.0 and relevant tests for data analysis.Results: The mean PSS score in the students was 26.96 (SD=6.332). Moderate stress and severe stress were present in 37.3% and 1.1% students respectively. Perceived stress was significantly associated with female sex, mother tongue; vastness of curriculum, dissatisfaction with clinical teaching, competition with peers and high parental expectations. More than 50% students felt that they were not able to adequately manage their stress. The most commonly used stress management techniques were social media usage and engaging in hobbies/sports.Conclusions: There is an urgent need for conducting screening programmes for stress in medical students and implementing measures which will equip them with skills to manage their stress.

Published: April 2018

Objectives: Clinical trials are prospective studies on human subjects designed to answer various clinical questions. However, only a limited number of clinical trials have been conducted in Oman. This study aimed to assess the knowledge and attitudes of Omani patients and their relatives towards participating in clinical trials. Methods: This cross-sectional study was conducted between October 2015 and March 2016 among 174 patients and relatives attending the Haematology and Oncology Outpatient Clinics and Day Care Unit of the Sultan Qaboos University Hospital, Muscat, Oman. A self-administered questionnaire was designed to elicit participants’ knowledge of and attitudes towards participation in clinical trials. Results: A total of 100 patients and relatives agreed to take part in the study (response rate: 57.5%). The male-to-female ratio was 1:1.2. Only 31.3% of the studied population knew what clinical trials were and only 6.5% had themselves previously participated in a clinical trial. The majority agreed or strongly agreed that they would participate in clinical trials related to their own condition (59.2%). Overall, 89.7% expected to be informed about potential clinical trials by their treating physicians. Conclusion: Omanis had a low level of knowledge of clinical trials and a very low rate of previous participation in such trials, despite a moderate level of interest. Patients should therefore be educated and informed of ongoing clinical trials in order to improve participation rates for clinical trials conducted in Oman.
