Authors: Makwero M. T. , Mollentze W. F. , Joubert G. , Steinberg W. J.
Published: October 2020

Background: Patients attending outpatient departments for follow-up of diabetes mellitus (DM) may seem content about the control of their disease. However, complications resulting from DM may present before diagnosis and treatment initiation or continue to develop while on treatment.Aim: This study aimed to report on the prevalence of DM complications in patients with DM at Maluti Adventist Hospital, Lesotho.Methods: A cross-sectional study was conducted in 150 DM patients recruited from Maluti Adventist Hospital’s newly formed clinic between May and June 2009. Demographic information was obtained through a structured interview. Patients underwent physical and eye examinations to obtain an anthropometric profile and identify DM complications. Laboratory and ECG investigations were done to establish level of glycaemic control and identify other complications.Results: Patients were female (80.7%) with a mean age of 58.2 years (standard deviation 13.2). Almost all patients had type 2 DM (94.7%) and 60.1% had been diagnosed during the preceding five years. The most common co-morbidity was hypertension (85.3%) and 49.7% of patients were obese (mean body mass index 30.4 kg/m2). Patients had poor short-term (46.2%) and longterm (57.5%) glycaemic control. Nearly half (43.3%) of the patients had evidence of peripheral neuropathy. Almost 60% of the patients had a blood pressure of 130/80 mmHg. Of the 128 patients seen by the ophthalmologist, 29.9% had evidence of cataracts in both eyes. Funduscopic abnormalities were found in 32.8% of the patients. Patients with complications or poor glycaemic control had been diagnosed for a significantly longer time.Conclusion: Patients showed evidence of DM complications at the time of study. Coupled with significant co-morbidities and high body mass index, the risk of morbidity and mortality is high. A comprehensive approach is needed in managing these patients, if meaningful reductions in morbidity and mortality are to be achieved.

The aetiology of atopic dermatitis is multi-faceted and affects our first line host defence, the skin. Atopic dermatitis has a significant influence on a patient’s social and occupational functioning and can have long-lasting effects. The signs and symptoms of AD includes pruritus, erythema, fissuring, and lichenification – these are reduced by the use of moisturizing agents. Guidelines on how to manage atopic dermatitis aims to improve symptoms and achieve long-term disease control. Patient education remains as important as other treatment strategies and the pharmacist plays an integral role in educating patients on the management of their condition and adherence to therapy.
A "site" for sore eyes
Authors: Muntingh George L. , Viljoen Michelle
Published: October 2020

It is known that not all red eyes are caused by infections. Furthermore, not all eye infections will react to antibiotic eye drops. Most cases of conjunctivitis are due to viral causes, do not require antibiotic eye drops and are usually self-limiting. Serious ophthalmic conditions such as infectious keratitis can lead to blindness; it is an emergency that requires specialist treatment. Also infectious endophthalmitis has become more frequent with the use of intravitreal injections. Intravitreal antibiotics are needed to try and prevent visual loss. To ensure therapeutic local exposure ophthalmic antibiotic solutions should be applied frequently into the eye.
‘Telephone Triage’: a possible means of managing the after-hours patient load at primary health care facilities in South Africa
Authors: Adeniji A. A. , Mabuza L. H.
Published: October 2020

The rate at which routine patients are using the emergency department (ED) as a path to enter into the healthcare system in South Africa’s community healthcare facilities and district hospitals is alarming. The increasing number of acutely presenting, less stable and routine patients are being left to the care of a reduced number of health carers after hours, at weekends and during public holidays. This circumstantial disproportionality forms the breeding ground for poor patient care, healthcare workers’ burnout and inappropriate use of referral pathways. Not all the patients occupying the ED waiting rooms actually need emergency care. A sizeable number of patients in the waiting line are routine cases that could wait without any undesirable clinical outcomes. This opinion paper looks into the use of telephones to control after-hours patient loads at primary health care facilities in South Africa.
Allergic skin conditions - causes, clinical features and treatment
Authors: Motswaledi Hendrick M.
Published: October 2020

Allergic skin conditions are caused by allergens. When an allergen is responsible for triggering an immune system response, this results in an allergic skin condition. Some of these allergens are physical agents which evoke an immune response by way of contact with the skin and some are food-stuffs and drugs taken systemically.Allergic skin conditions include urticaria and angio-oedema, allergic contact dermatitis, atopic dermatitis, hand dermatitis, photoallergic reactions and phototoxic reactions. These conditions are briefly discussed in this article.
Quality of primary care physicians’ communication of diabetes self-management during medical encounters with persons with diabetes mellitus in a resource-poor country
Authors: Ojo O. S. , Malomo S. O. , Egunjobi A. O. , Jimoh A. O.A. , Olowere M. O.
Published: October 2020

Background: Most of the Nigerian studies on the determinants of diabetes self-management have focused on patient-related factors. There is no previous local study that examined the quality of diabetes self-management education provided by primary care physicians to people with diabetes mellitus.Methods: A descriptive cross-sectional study was conducted among 105 primary care physicians during a workshop. The quality of diabetes self-management education provided by the physicians was assessed using a self-designed scale of 39 Likert questions derived from American Association of Diabetes Educators seven domains of diabetes self-management. Cronbach’s reliability coefficient of each domain/subscale was ≥ 0.7. The data was analysed using the independent sample t-test and one-way ANOVA.Results: Over half of the physicians provided ‘inadequate quality’ diabetes self-management education in all the domains. Physicians had the highest mean score in the ‘taking medication’ domain (4.35 ± 0.59). The mean scores in the ‘problemsolving domain’ (3.63 ± 0.74) and the ‘being active domain’ (3.57 ± 0.71) were low. The quality of diabetes self-management education provided by the physicians was not associated with any of the physician characteristics.Conclusion: The quality of physicians’ communication of diabetes self-management was suboptimal in this study. The majority of the adequately communicated diabetes self-management behaviours were risk factors reduction related and disease-centred. Thus, training of primary care physicians on diabetes self-management education is recommended because of the key role these physicians play in diabetes management in resource-poor countries.
Biomarkers, shock index and modified early warning score among older medical hospital inpatients in Nigeria
Authors: Adebusoye L. A. , Owolabi M. O. , Ogunniyi A.
Published: October 2020

Background: Biomarkers, shock index and modified early warning score (MEWS) are of public health importance because identification and prompt attention to them have been found to reduce mortality among older patients on admission.Objectives: A study was undertaken to determine the biomarkers, shock index and MEWS that predict mortality on admission among older medical hospital inpatients.Methods: This was a prospective study of 450 patients (≥ 60 years) on the medical wards of University College Hospital, Ibadan. Biomarkers recommended by the National Institute on Aging such as blood pressure, heart rate and pulse rate (cardiovascular functioning); cholesterol and triglycerides (metabolic processes); T-cell counts (immune system status) and weight, body mass index and waist-to-hip ratio (indicators of obesity, chronic metabolic disorders and fat deposits) were assessed. Vital signs were recorded on admission and used to calculate the shock index and MEWS. Multivariate and survival analyses were carried out at p 0.05.Results: Baseline temperature ≥ 39.0°c (p = 0.049), pulse rate ≥ 100 beats/minute (p = 0.034), systolic blood pressure (SBP) 120 mmHg (p = 0.048), shock index ≥1.0 (p = 0.041), age shock index (p = 0.032) and critical illness score (MEWS ≥5) p = 0.019 were significantly associated with mortality. Independent predictors of mortality on Cox regression analysis were temperature ≥ 39.0°C (HR = 3.317 [1.281–8.590]) and SBP 120 mmHg (HR = 1.845 [1.025–3.322]).Conclusion: Prompt identification and management of fever and low blood pressure should improve the survival of older medical hospital inpatients.

The Political Economy of Commercial Agricultural Land in Ethiopia
Authors: A. Mamo Siyum , D. Habte Abiot
Published: October 2020

This paper provides a critical examination of the political economy of commercial agricultural land in Ethiopia, taking a case from the peripheral State of Gambella where the Anyuaa and the Nuer ethnic groups interact. Since 2002, the government of Ethiopia has pursued a controversial investment approach that promotes large-scale investment dominated by FDI while officially denouncing the current wave of the neoliberal economic discourse. Such investment ventures in the State of Gambella have put significant agricultural lands under a long-term lease to foreign developers. The central argument of this study lies in the point that, in a political economy avenue where practices contradict official state ideology, mechanized agricultural developments face failure beyond adverse social and ecological crises. Under the guise of the political economy of development where the state takes in hand the responsibility for playing a leadership role, private developers cannot easily find a space for leverage for making productive investments. Rather, such ventures as the case of Gambella tend to institute land alienation of the rural indigenous poor who are already marginalized because of their double-peripheral positions – a manifestation of South in the South. The consequence of both inter-group relations and the environment is catastrophic. The paper concludes that the influence of (trans)national companies on indigenous communities living especially in fragile environments continues to be disconcerting whereas the conflation of the neoliberal inspiration in the peripheral regions appears to be disguising while leaving the local environment and inter-group relations at stake. Thus, the Ethiopian government should recognize the contradiction between its official ideology and the investment practices in agricultural lands overtaken by (trans)national developers.

Published: October 2020

There have been calls for pre-service teachers to be equipped with leadership skills. The 21st century urges schools and colleges to prepare the next generation of teachers to have leadership skills and to foster these skills among their students in the classroom. Pre-service teachers need to be equipped with leadership skills to be capable of making real changes in society. This study was conducted to examine to what extent pre-service teachers in Bahrain Teachers College possess leadership skills and the strategies faculty ought to use to improve those skills. A validated survey consisting of eight categories of leadership skills was used to collect the data. The sample consisted of 177 students from different majors (Arabic and Islamic, English, Maths and Science, and Cycle One). The results showed that pre-service teachers possess leadership skills and confirmed developing these skills in the classroom. The pre-service teachers enhanced their leadership skills in planning, problem-solving, self, and other management/controlling, communication, teamwork, decision-making, motivating, evaluation. Furthermore, the participants identified teaching strategies such as group presentation, group work, project-based learning, and problem-based learning as the strategies used by faculty in teaching, which they said facilitates the development of leadership skills in the classroom.

Abstract

Objectives: The present research was carried out to find out an estimate of gelotophobia among obese individuals. Perceived stress and differences on socio-demographic factors were also studied.

Method: The survey design cross-sectional study was conducted from January to June in 2018. A sample of 70 consenting participants (men = 22, women = 48) with BMI ? 25 were recruited through purposive sampling. The instruments of Geloph<15> and Perceived Stress Scale (PSS) were used to assess the level of gelotophobia and level of stress in the sample. Demographic details of sample were also recorded to achieve study objectives.

Result: The estimate of gelotophobia among obese individuals in the current study showed that 64.2% majority sample had moderate level of gelotophobia, while 10% of the sample had high level of gelotophobia. Statistically significant differences were observed in the level of gelotophobia among individuals having different levels of socio-economic status (p < .05) and with history of being ridiculed by peers (p < .05). However, the present study did not show any significant demographic difference in perceived stress (p > .05).

Conclusion: The findings of the study could provide evidence in favour of developing and implementing suitable intervention programs to help control risk of gelotophobia among obese individuals. The study could also assist in creating awareness and understanding about harmful consequences of bullying and nurturing a healthier narrative of conversations and humour among the youth.

Keywords: Humor fear, obesity, BMI, body weight.

Efficiency Control Improvement Of Diesel Engines Conditions By Using The Method Of Analytical Synchronization Of Monitored Data
Authors: Zalozh Vitalii , Tarasenko T , Varbanets R
Published: October 2020

Improving the efficiency of the ship's diesel power plant is becoming increasingly important every year. This is primarily due to the restrictions on emissions of sulfur and nitrogen oxides into the atmosphere during the operation of the ship's diesel engines. Article is devoted to the problem of synchronization of data monitoring working process in transport diesel engines operation. The accuracy of data synchronization determines the error in determining power, control of the main engine systems operation and its diagnostics. The method of solving the synchronization problem must be analytical. The method of solving the synchronization problem must be analytical. In comparison the hardware methods used in most diagnostic systems of the working process of diesel engines have several disadvantages. It is impossible to conduct rapid diagnostic control in operation, non-stationary phase and amplitude errors in calculation the main parameters of the working process, the need for preparatory operations and related need for temporary withdrawal of diesel engine operation, complexity and high cost of diagnostic control. An analytical synchronization method is developed based on the top dead center coordinate determination algorithm, which uses three stages: linear, sinusoidal and model equal to zero the first derivative of the pressure under compression. The proposed method of analytical synchronization gives the obvious advantages for monitoring working process systems of diesel engines. The error in determining the main parameters of the working process and the indicator power does not exceed 2.5%.
SEXTING AND RISKY SEXUAL BEHAVIOUR AMONG STUDENTS IN MACHAKOS UNIVERSITY, MACHAKOS COUNTY.KENYA
Authors: Mukonyo Musyimi Elizabeth , Kabue Priscilla , Mugo Judy
Published: October 2020

Purpose: The purpose of this study was to investigate sexting practice among students and identify the risky sexual behaviors associated with sexting among students in Machakos University, Machakos County, Kenya.

Methodology: The study adopted a descriptive cross-sectional study design. The target sample was 347 students aged 18-24 years in Machakos university. Convenience sampling was used for quantitative data and purposive sampling for qualitative data as well as the study area. Interviewer-administered questionnaires were utilized and in-depth interview used for the qualitative data collection. The IBM SPSS version 26.0 was used for data analysis. Thematic analysis was used to analyze the qualitative data and triangulated with quantitative findings. Results was presented in tables, graphs and pie charts. Chi square test was done to identify variables associated with sexting and odds ratio to measure the association between sexting and risky sexual behavior.

Findings: Sexting (sending of sexually suggestive image/photo) was found to be prevalent among the student at 57% and 48% being two-way sexters. Male respondents engaged more into sexting as compared to female respondents at 67%and 33% respectively.23.0% sexted to keep or get a boy/girlfriend and 14% due to pleasure from their peers. Gender, Age, Level of study and relationship status were all significantly associated with sexting (P=0.000, P=0.027, P=0.002 and P=0.022 respectively). Risky sexual behaviors among students included early sexual intercourse 74%, but 54% had not used protection. Sexting and risky sexual behavior were found to be associated because most of the respondents who engaged in sexting were eight times more like to engage in early sexual intercourse, and the perception of sexters was that if one was sexting they were six times likely to have sex with the person they sexted, and so the null hypothesis that there is no relationship between sexting and risky sexual behavior was rejected and the alternative hypothesis adopted.

Unique contribution to theory, practice and policy: Adoption of Multi sectoral to develop policies, and design youth programs with a wide range of issues relating to sex and sexuality and how to safely navigate the internet and form healthy relationships both on and offline, which include issues such as sexting with young people from a young age.
Governmentality and the Image
Authors: Tomanić Trivundža Ilija , Tagg John
Published: October 2020

John Tagg is one of the most prominent contributors to critical theory and history of photography. In the interview, he talks about the contemporary relationship between (photographic) image and governmentability, on the asymmetrical distribution of power relations that it implies and on the possibilities of resistance to the omnipresent social surveillance. Within the contemporary apparatuses and machineries of surveillance, the image often represents only a nodal point for collection of nonvisual information. As the value of the image within these machineries shifts away from their representational character, the image is increasingly becoming weaponized and is in the final instance, destined to become a trigger rather than visualisation device of the apparatuses of social control. Therefore purely visual strategies of resistance, such as camouflage, are not sufficient to fight against the increasingly automated machineries of social control and changed conditions of governmentability.

Published: October 2020

Este estudo recupera a trajetória dos programas de orientação sexual realizados na rede municipal de ensino de São Paulo entre 2001 e 2005. Analisa as características dos programas, a articulação intersetorial entre as Secretarias da Educação e da Saúde e os desafios para a continuidade na mudança da gestão. Os dados provêm de fontes documentais e de entrevistas em profundidade com oito coordenadores e consultores dos programas. Os achados evidenciam um baixo grau de articulação dos programas em função da ausência de uma política pública consistente nesse campo. As práticas de gestão na educação e na saúde reproduziram uma racionalidade setorial, fragmentada e tradicional. Nesse cenário, os projetos ora se interceptaram, ora concorreram entre si. Constatou-se que a intersetorialidade enquanto premissa e estratégia para o fortalecimento das políticas públicas é um desafio para os formuladores, equipes técnicas e gestores de programas públicos.
Revisão dos conceitos da profilaxia antivariólica no Brasil colonial
Authors: Silva Camila Sloboda Pacheco da
Published: October 2020

Ao elaborar o presente trabalho, detive-me longamente na pesquisa sobre a melhor maneira de enfocar os conceitos que condicionaram rigorosamente a profilaxia antivariólica no Brasil do período colonial. Mais especificamente, ocorreu-me a ideia de definir as práticas desenvolvidas entre o século XVI e o século XIX referentes à possibilidade de reduzir a incidência e prevenir a enfermidade. Este trabalho remonta parcialmente às noções acerca do contágio e de sua possível prevenção para aprofundar a análise da erradicação da varíola, ficando, portanto, muito aquém de exaurir o assunto, podendo a pesquisa ser ampliada quer sobre a prática do método da inoculação por médicos brasileiros, quer na teoria da introdução da vacina antivariólica.
O pioneirismo da Bahia no isolamento do vírus da “gripe coreana” em 1951 e a possibilidade de desenvolvimento de uma vacina específica
Authors: Vieira Guilherme Augusto , Baiardi Amílcar
Published: October 2020

O presente trabalho constrói a historiografia de um fato científico-tecnológico pouco conhecido, que foi o isolamento do vírus da gripe que assolou o Brasil em 1951. O isolamento do vírus da “gripe coreana”, ocorrido em laboratórios do Estado da Bahia, foi de grande relevância para o combate à doença na época, uma vez que permitiu sintetizar uma vacina específica e eficiente para o combate à pandemia. A técnica utilizada foi a de inoculação e isolamento de vírus em ovos embrionados de galinhas, que se mostrou mais eficaz que o procedimento em mamíferos. As pesquisas foram realizadas no Instituto Biológico da Bahia e no Instituto de Saúde Pública da Fundação Gonçalo Muniz, pelo professor e pesquisador Fúlvio Alice. Os ensaios de laboratório confirmaram a maior eficácia de vacinas produzidas com vírus isolado em embriões comparativamente às importadas.
Desenvolvimento da infraestrutura para abastecimento de água na capital paulista durante o século XX
Authors: Massara Vanessa Meloni
Published: October 2020

Este artigo pretende fornecer uma visão geral sobre a implantação e a expansão da infraestrutura de abastecimento de água na cidade de São Paulo durante o século XX, mostrando a evolução da sua distribuição territorial associada a informações numéricas sobre a extensão das redes, o número de ligações e a população atendida. Através da breve narrativa histórica, é possível verificar que a expansão do serviço de água canalizada na capital paulista seguiu a ocupação do território, partindo do centro, no final do século XIX, até chegar aos extremos leste e sul do município, entre as décadas de 1970 e 1980, e aos 100% de atendimento ao final dos anos 1990.
Dificuldades de comunicação científica em um contexto de censura: o caso Galileu
Authors: Rodrigues Wellington Gil , Baiardi Amílcar
Published: October 2020

O objetivo deste trabalho é destacar como atuavam os mecanismos de censura da Igreja Católica e as estratégias operadas por Galileu para comunicar os conhecimentos científicos em um contexto de censura. As questões principais que se busca responder são: quais os mecanismos utilizados pela Igreja Católica para impedir a livre circulação das ideias de Galileu e quais as estratégias empregadas pelo filósofo para comunicar suas descobertas diante dos obstáculos postos pelos dogmas religiosos. A metodologia utilizada consistiu em leitura, questionamentos e interlocução crítica, envolvendo material documental e bibliográfico. O trabalho é dividido em três partes. A primeira aborda os mecanismos de censura utilizados pela Igreja no contexto histórico. A segunda parte destaca as aplicações dos mesmos no caso Galileu. Na terceira parte se focalizam os resultados provenientes da aplicação da censura baseada no decreto inquisitorial após a publicação do livro intitulado Diálogo e durante o julgamento de Galileu, em 1634. A engenhosidade de Galileu para contornar a censura é destacada, principalmente a partir de 1616.
O poder do conhecimento da linha em Galilei, Hobbes e Hooke
Authors: Bredekamp Horst
Published: October 2020

Desenhos, aquarelas, gravuras em cobre e água-forte podem formar construções em filigrana, extremamente refinadas, que chegam até à elaboração imaterial de um pensamento, mas que também permitem uma reprodução a mais direta possível dos objetos. Essa dupla posição do visual inspirou três pesquisadores do séc. XVII, que foram bem-sucedidos na visualização da superfície da lua (Galileu Galilei), do domínio do Estado (Thomas Hobbes) e do mundo microscópico (Robert Hooke). Ao menos nesses exploradores do estelar, do político e do microbiano, a separação entre “pensamento e contemplação” dissolvese numa intensa simbiose.

O FERTICALC-Batata foi desenvolvido, para obter um modelo matemático que seja mais concordante com a realidade. O objetivo do trabalho foi calcular o módulo requerimento para a cultura da batata por meio da recopilação de informações disponíveis na literatura científica. A demanda da planta por um nutriente i (dNui) resulta do somatório dos conteúdos (c) dos nutrientes (i) nos diferentes compartimentos da planta (j) (tubérculo (t), folhas (f), caules (c) e raízes (r) com o que posteriormente será calculada a demanda total da planta. Foi calculada a demanda para Solanum tuberosum subsp. tuberosum, para 8 estratos de produtividades que são 15, 20, 25, 30, 35, 40, 45 e 50 t/ha, para os macronutrientes e os micronutrients os CUB (coeficientes de utilização biologica) encontrados por planta espresados em (kg/kg) são: N (163,29; 159,59), P (1793,91; 1207,80), K (102,51; 117,97), Ca (1622,72; 823,62), Mg (1982,73; 1272,38) S (2448,29; 1732,96), os resultados confirmam a alta demanda da cultura pelo K que dentre os dados é o CUB mais baixo, indicando que por kg de nutriente utilizado produz a menor quantidade de massa de matéria seca, esses coeficientes se consideram altos ao ser comparados com os obtidos para outras culturas como melão que para N, P, K, Ca, Mg e S foram 66, 189, 30, 96, 485 e 297 kg/kg respectivamente, indicando a maior eficiencia da batata na utilização dos nutrientes. Com o uso destes coeficientes será estimada a demanda total da planta com as taxas de recuperação obtidas também da literatura.
ESPECIES ACUATICAS DE LOS HUMEDALES DE BOGOTÁ, COLOMBIA CON CAPACIDAD PARA EL TRATAMIENTO DE AGUAS RESIDUALES CON METALES PESADOS: REVIEW
Authors: Pérez de Arco Kenny , Castelblanco Lancheros Johana
Published: October 2020

El presente estudio busca reconocer que especies acuáticas con presencia en los humedales de Bogotá pueden tratar aguas residuales según el tipo de metales pesados y así presentar la información de manera tal que la comunidad pueda generar procesos de diseño más eficientemente. Lo anterior evitar el uso de especies exóticas o que no sean útiles para la retención y/o absorción de ciertos metales pesados. La metodología empleada inicio con una compilación de la información de todas las especies acuáticas con presencia en los humedales de la ciudad, posteriormente se realizó la búsqueda en bases de datos por cada especie sobre la capacidad de bioacumulación de metales pesados y finalmente, se analizó y ordeno la información encontrada.Como resultado se encontraron 48 especies acuáticas, de las cuales, 24 especies no cuentan con información alguna, 14 requieren una revisión más detallada, 1 especie (utricularia gibba) no puede ser usada en procesos de tratamiento debido a su alta sensibilidad frente a cambios en el ecosistema y especies como holcus lanatus son altamente selectivas con respecto a la resistencia y acumulación de metales pesados, las 24 especies restantes muestran una capacidad variable en la acumulación y se ve afectada por factores como pH y concentración de metales pesados; se puede concluir que las especies presentes en los humedales de Bogotá no son híper acumuladoras y que se  debe incentivar el uso de plantas nativas ya que no actúan como plantas invasoras, evitando así él riesgo de desplazar especies nativas o endémicas.
