Authors: Almashari Suhaib , Al-Malki Yasir , Al-Riyami Adil , Nadar Sunil K. 
Published: April 2021

Objectives: To assess causes of delay for presentation with ST elevation myocardial infarction(STEMI) at our institution. Methods: We included patients with a STEMI that were taken up for primary angioplasty, who had presented from Jan 2017 to December 2019 to the emergency department at Sultan Qaboos university hospital, Muscat. Results: 101 patients (Mean age 54.8+10.8 years; 80 (79.2%) male) were included. The median (IQR) pain to door time was 60 (30-120) minutes. 66 (66%) patients arrived within 90 minutes. All except one arrived by privately arranged transport. Feeling that the pain was not important (60%) or not cardiac (22%) were the main reasons for delay. Being diabetic was the only patient factor that predicted delay. Conclusion: A high proportion of patients presenting to our institution with a STEMI arrived within recommended times. However more public education is required to improve awareness about the importance of early evaluation of chest pain.
Keywords: Acute myocardial infarction; prehospital delay.

Published: April 2021

Objectives: To obtain information on the nutritional maintenance effects of Ninjinyoueito (NYT) in elderly patients with chronic wasting disease, a retrospective study was conducted. Methods: we investigated changes in bodyweight and serum levels of total protein and albumin in patients who received NYT for more than 6 months for chronic wasting diseases in our hospital from April 2009 and October 2019. Results: During the study period, 11 patients (median age: 75 years) had NYT for 6 months or more. The median administration period of NYT was 14 months. The bodyweight, serum total protein, and albumin at the time of last observation were not statistically different from those at the time of the start of NYT administration (p=0.1755, p=0.7659, p=0.5498, respectively). Conclusions: Our study suggested the possibility of maintaining nutritional condition by NYT in elderly patients with chronic wasting disease of various etiologies. More evidence will be required to confirm our results.

Mediastinal hydatidosis with an unusual presentation
Authors: Dantis Klein , Gupta Nilesh 
Published: April 2021

Hydatidosis is a common zoonotic disease with high prevalence in developing countries. While solitary cyst with unilateral lung involvement is common, bilateral involvement and multiple cysts are rare, seen in 20% and 30% of the cases. Likewise, extensive involvement of extrapulmonary tissues and mediastinum is rare. We report an unusual case of mediastinal hydatidosis mimicking an intrathoracic malignancy in a 24-year-old female. She presented with a history of left-sided chest pain and heaviness in the left hemithorax for a period of two months. Diffuse, multiple fluid-filled cystic lesion with internal echoes throughout the mediastinum, lung, pericardium, diaphragm and chestwall were observed in contrast-enhanced computed tomography of the thorax. An incidental cystic lesion in liver was noted. Since serology for echinococcosis was negative, a differential diagnosis of intrathoracic malignancy was considered. However, intraoperative and histopathologic findings were suggestive of hydatidosis.

Allelopathic Potentiality of Euphorbia hypericifolia L. on Germination and Seedling Development of Sympatric Crops and Weeds
Authors: Ndam Lawrence Monah , Ngone Abwe Mercy , Nkongho Raymond Ndip , Fongod Augustina Genla Nwana , Fujii Yoshiharu 
Published: April 2021

Euphorbia hypericifolia, a non-native herbaceous weedy plant was found to often form disproportionately dense, virtually monospecific stands in the Mount Bambouto Caldera, Cameroon. This observation is within the purview of allelopathy and is attributed to the release of botanicals by non native plants that harm naïve native flora, creating significant problems for agriculture and the environment. We investigated if the invasiveness of E. hypericifolia could be explained by its allelopathic potential at varying concentrations on five indicator plants. The results showed that the leaf, root and stem aqueous extracts of the plant exhibited significant inhibitory effects on the germination, radicle and plumule lengths of Biden pilosa, Amaranthus spinosus, Lactuca sativa, Zea mays and Lycopersicon esculentum at 100 % by 75.0, 69.4, 95.6, 28.0 and 97.2 %, respectively. The leaf extract was the most potent, while the stem extract was the least. The extract of E. hypericifolia was stimulatory (Lower concentrations) and inhibitory to the germination and growth of the test plants and its effect was concentration-dependent with the roots of target plants being more sensitive to the extracts than the plumule. L. esculentum was the most susceptible species to E. hypericifolia extracts while Z. mays was more tolerant than any of the tested plants. Results of total chlorophyll pigment accretion showed declining levels of chlorophyll detected in the leaves of tomato transplants cultivated in the augmented soils with rising dosage of the leaf residue of E. hypericifolia. B. pilosa planted on E. hypericifolia infested soil (EIS) showed very poor emergence recording only 7.5 % after 6 weeks as compared to 83.0 % in non E. hypericifolia infested soil (NIS). Qualitative phytochemical screening indicates E. hypericifolia is rich in secondary metabolites including alkaloids, glycosides, flavonoids, phenolics, tanins, Steriods and saponins. Acetone was the best extractant amongst the solvents used. This study has proven the allelopathic potential of E. hypericifolia and revealed some allelochemicals that may be exploited for the development of bioherbicides and plant growth promotion from natural products.

Published: April 2021

Este artigo trata da educação popular a partir de uma perspectiva bem específica: a formação para o emprego de alunos em situação de vulnerabilidade, com baixo nível educacional e oriundos de meios sociais modestos e com poucas oportunidades educativas. Nossa contibuição toma como ponto de partida a escola técnica Parque Miraflores, em Sevilha (Espanha). Trata-se de uma iniciativa dos movimentos sociais que tem funcionado durante duas décadas. Discutimos os princípios da educação popular e participativa, aplicando-os às escolas técnicas que surgiram na Espanha em momento posterior à ditadura de Franco. Apresentamos o marco atual da formação para o emprego, destacando a necessidade de combinar preparação profissional e desenvolvimento social e pessoal. Finalmente, ressaltamos as dimensões de educação popular e participativa presentes no caso analisado, comentando suas implicações para a formação socioeconômica, cultural, sindical, acadêmica e laboral.
Ações educativas desenvolvidas por prostitutas organizadas
Authors: Sousa Fabiana Rodrigues de 
Published: April 2021

O presente artigo é elaborado com base em reflexões tecidas ao longo de pesquisa de pós-doutoramento realizada com prostitutas que fazem parte de associações da categoria localizadas nas cidades de Belo Horizonte (MG), Campina Grande (PB), João Pessoa (PB) e Recife (PE), com intuito de desvelar processos educativos consolidados no exercício do trabalho sexual e na trajetória de militância dessas mulheres na busca por seus direitos. Com base no referencial da Educação Popular, ao longo do percurso metodológico desta investigação buscamos – pesquisadora e prostitutas – identificar e analisar saberes de experiência construídos nas ações educativas e culturais desenvolvidas por essas mulheres. Os resultados da investigação engendram o entendimento de que o processo de organização de prostitutas em associações tem sido relevante para fortalecer a leitura crítica da realidade, possibilitando o desenvolvimento da autoestima e autoconfiança necessárias capazes de impulsioná-las ao engajamento na busca por seus direitos. As ações educativas realizadas por essas mulheres funcionam como círculos de cultura, nos quais elas vêm apresentando seus anseios, sua estética e afirmando sua condição de sujeito.
Leituras de jovens de camadas populares

Published: April 2021

Este trabalho apresenta resultados da pesquisa “Letramentos em contextos do campo: práticas escolares e não escolares em comunidades rurais”. A investigação objetiva compreender práticas de leitura e escrita de jovens do campo realizadas na escola e nas suas comunidades. Esta análise considerou dados levantados por meio de questionários aplicados aos alunos de duas Escolas Família Agrícola (EFA), de ensino secundário técnico em agropecuária. Contou-se, ainda, com depoimentos gravados em vídeos, observações in locoe registros fotográficos. Em razão do regime de alternância praticado nessas escolas, considerou-se propício o fato de os alunos vivenciarem um projeto pedagógico que preconiza vínculos mais estreitos entre conhecimentos escolares e não escolares. Os dados coletados indicam a heterogeneidade de repertórios de leitura e de escrita nas práticas de letramento na escola e no ambiente familiar e sinalizam ora a presença de uma visão pragmática relativa ao mundo do trabalho, previsto para um contexto de formação em que um conhecimento técnico é exigido, ora a influência de referências culturais e de leituras valorizadas socialmente. Esse hibridismo aponta a maleabilidade das fronteiras, relativizando uma hipótese de caracterização homogênea de práticas de leitura e de escrita vivenciada pelos jovens em contextos rurais.
Efficacy of a Web-Based Intervention (Smart Choices 4 Teens) for Facilitating Parent-Adolescent Communication About Relationships and Sexuality: Randomized Controlled Trial
Authors: Bourdeau Beth , Miller Brenda A , Byrnes Hilary F , Woodall W Gill , Buller David B , Grube Joel W 
Published: April 2021

Background
There is a need for interventions that promote healthy decision making among adolescents and leverage the ongoing impact of parental relationships through older adolescence and young adulthood. These interventions should maximize adolescent engagement and be easily accessible to families in terms of cost, duration, and logistics related to participation.

Objective
This study aims to test the efficacy of the healthy relationships and sexual decision-making component of a web-based intervention for older adolescents and their parents, ascertain whether the efficacy varies by gender, and assess its efficacy over time.

Methods
A randomized controlled trial was conducted for the web-based, self-paced intervention Smart Choices 4 Teens from 2014 to 2015. Families (N=411) with adolescents aged 16-17 years were randomly assigned to the intervention or control condition. Surveys assessing aspects of sexual communication were administered at baseline and at 6, 12, and 18 months. Generalized estimating equations were used to determine the impact of exposure to the relationships component of the intervention on sexual communication by parents, as reported by adolescents.

Results
Less than half (88/206, 42.7%) of the intervention group participated in the third and final intervention component, which was focused on relationships and sexual decision making. Participation in the relationships component increased the frequency of parental sexual communication and increased the number of dating rules after accounting for other significant adolescent characteristics. The impact of the intervention varied little by gender, although it did demonstrate an impact on communication reports over the follow-up survey administrations.

Conclusions
Smart Choices 4 Teens demonstrated efficacy in increasing the frequency of sexual communication between parents and adolescents in the long term.

Does Wearing a Face Mask During the COVID-19 Pandemic Increase the Incidence of Dermatological Conditions in Health Care Workers? Narrative Literature Review
Authors: Wilcha Robyn-Jenia 
Published: April 2021

Background
COVID-19 is a health emergency. SARS-CoV-2 was discovered in Wuhan (Hubei Province, China) and has rapidly spread worldwide, leaving no country untouched. COVID-19 is a respiratory infection characterized by a pneumonia of unknown etiology. It is transmitted through respiratory droplets; for example: through breathing, talking, and coughing. Transmission of the virus is high. Health care workers play important roles in helping those affected by COVID-19; this could not be done without the use of personal protective equipment (PPE). PPE involves the use of goggles, masks, gloves, and gowns and is known to reduce COVID-19 transmission; however, multiple reports of skin disease and damage associated with occupational mask-wearing have emerged.

Objective
The objective of this study is to review the literature for newly emerging dermatological conditions as a result of occupational mask-wearing during the COVID-19 pandemic.

Methods
A narrative review of new reports of dermatological conditions associated with occupational mask-wearing was carried out in May 2020 by referencing keywords including: “covid mask dermatology,” “covid dermatological damage,” “covid mask skin,” “covid N95 mask damage,” and “covid mask skin damage” from PubMed, supplemented by searches on both Google Scholar and ResearchGate. A total of 287 articles were found, of which 40 were successfully included in this study, and an additional 7 were selected from the reference lists of these 40 articles. The findings were tabulated and analyzed under the following headings: dermatological diagnosis, causes, and management.

Results
Qualitative analysis of the reviewed data was carried out. A number of dermatological conditions were found to increasingly occur owing to prolonged and frequent use of face masks. Pressure-related injuries were often the most serious complaint; recommendations to reduce this type of injury include the use of hydrocolloid dressings, plastic handles, education, and regular moisturization. Innovation in PPE as well as services, such as virtual clinics, need to be advanced to protect the welfare of health care staff.

Conclusions
In these unprecedented times, PPE has been an effective barrier to the transmission of COVID-19 among health care workers. This has allowed health care workers to provide care to patients, with minimal risk. However, our findings suggest that despite the obvious benefits of using face masks to protect the respiratory system, there are also considerable health consequences to the skin. Future research studies are required to focus on improving face masks to ensure both the protection of the respiratory system as well as skin care, which, according to our study, has been overlooked.
