Objectives:

Infection prevention and control (IPC) practice in health facility (HF) is abysmally low in developing countries, resulting in significant preventable morbidity and mortality. This study assessed and compared health workers’ (HWs) practice of IPC strategies in public and private secondary HFs in Kaduna State.

Material and Methods:

A cross-sectional comparative study was employed. Using multistage sampling, 227 participants each were selected comprising of doctors, midwives, and nurses from public and private HF. Data were collected using interviewer-administered questionnaire and observation checklist and analyzed using bivariate and multivariate analysis. Statistical significance determined atP< 0.05.

Results:

The practice of infection prevention was poor. Overall, 42.3% of the HWs did not change their gowns in-between patients, with the significantly higher rates in 73.1% of private compared to 42.3% of public HF workers (P< 0.001). In addition, 30.5% and 10.1% of HWs do not use face mask and eye goggle, respectively, when conducting procedures likely to generate splash of body fluids, however, there was no significant difference in these poor practices in public compared to private HFs. The mean IPC practice was 51.6 ± 12.5%, this was significantly lower among public (48.8 ± 12.5%) compared to private (54.5 ± 11.9%) HF workers (P< 0.0001). Private HF workers were 3 times more likely to implement IPC interventions compared to public HF workers.

Conclusion:

IPC practice especially among public HF workers was poor.

Authors: Alexander Sajin , Mysore Venkataram , Hirevenkangoudar Ashwini L.
Published: August 2021

Low-dose oral minoxidil (OM) has increasingly been used by many doctors around the world as a treatment option for hair loss. Sufficient data regarding its effect and side effect profile are lacking. An online search was done on PUBMED and GOOGLE SCHOLAR for articles that used OM as a treatment option for hair loss. Doses ranging from 0.25 to 5 mg have been used for treatment in various studies. Good compliance and tolerability have been noticed with low-dose OM therapy. Adverse effects are few and are mild with hypertrichosis being the most common adverse effect in a majority of the studies, the risk of which increases with an increase in dosage of the drug.

Authors: Khalil KotbAbbass Metwalley , Jansson Leif
Published: August 2021

Sepsis is life-threatening organ dysfunction caused by dysregulated host responses to infection, and septic shock is a subset of sepsis in which underlying circulatory and cellular/metabolic abnormalities are sufficiently profound to substantially increase mortality. Patients with sepsis are usually treated in the intensive care unit (ICU). Hence; under the light of above-mentioned data, the present study was undertaken for determining the correlation of lactate /albumin ratio in outcome of patients of sepsis in ICU. The present study was undertaken for determining the correlation of lactate /albumin ratio in outcome of patients of sepsis in ICU. A total of 30 patients were enrolled. The resulting patients were subjected to detailed history and examination followed by investigations (CBC, ESR, CRP), Bacterial culture, liver function test, renal function test, arterial blood gas analysis for lactate, serum albumin level). Mean Lactate value was 4.59 while mean albumin value was 25.12. Mean lactate to albumin ratio was 0.18. While correlating lactate to albumin ratio with Serum Procalcitonin levels, significant results were obtained. While correlating lactate to albumin ratio, it was seen that higher lactate to albumin ratio was associated with higher mortality. Lactate/albumin ratio is an independent predictor for the mortality among sepsis patients admitted to ICU.

Published: August 2021

Este artigo trata do problema histórico das finalidades potencializadas por materiais didáticos indicados para o ensino de matemática escolar, no contexto brasileiro da vaga pedagógica da Escola Nova. Mais especificamene, analisa o Pequeno Contador, criado e divulgado pelo educador baiano Alípio Franca, na primeira metade do século XX. A fundamentação teórica e metodológica compreende a histórica cultural no sentido de atribuir os significados históricos da cultura escolar, das finalidades das disciplinas escolares e dos saberes produzidos historicamente pelos protagonistas da educação escolar e dos meios adotados na produção de conhecimentos no ambiente escolar. Os resultados apontam que a finalidade desse material escolar, por consistir em um instrumento “multidisciplinar” da educação econômica, seria a reprodução social da vida adulta na escola, visto que está em consonância com o momento pedagógico do período em que foi produzido, circulado e apropriado. Expressou características do método ativo, perfazendo um recurso didático que representava a modernização da instrução escolar na época considerada.
A abordagem da subtração nos manuais das escolas normais primárias e do Ensino Primário, no início do século XX
Authors: Esteve Santiago Ana Elisa Esteves
Published: August 2021

Este artigo discute a abordagem da subtração em três obras do início do século XX: duas usadas na formação de professores para o Ensino primário relacionadas com Matemática e Pedagogia e outra usada como manual escolar do Ensino Primário, em Portugal. Tem-se como objetivo perceber a abordagem que apresentavam relativamente a esta operação aritmética, do ponto de vista matemático e didático. Para tal foi utilizada a metodologia de investigação histórica, através da análise documental de fontes primárias. Começou-se por analisar o que referiam os programas do Ensino Primário e do Ensino Normal, relativamente às operações aritméticas, em particular a subtração para depois se proceder à análise de cada uma das obras, na parte relativa à operação aritmética subtração. Observou-se que as obras apresentam diferentes formas de abordar a subtração, apresentando diferentes métodos (compensação ou decomposição). Também os exercícios apresentam diferenças, nomeadamente em relação à quantidade. Verificou-se ainda que as três obras abordam as três situações (caso em que cada número é apenas representado por um algarismo, caso em que todos os algarismos do diminuendo são maiores do que os do diminuidor e caso em que nem todos os algarismos do diminuendo são maiores do que os do diminuidor).
Mas afinal o que são problemas? Uma análise histórica sobre mudanças em definições, finalidades e tipologias
Authors: Bertini Luciane Fatima , Souza Andreia Fernandes
Published: August 2021

Neste texto, a partir da análise de diferentes documentos escolares, tais como livros/manuais, artigos de revistas pedagógicas e programas de ensino, bem como pesquisas já realizadas no âmbito da História da educação matemática (BERTINI, 2018; MACIEL,2019; OLIVEIRA, 2017; PAVARIN, 2020; SOUZA,2017), discutem-se as transformações ocorridas em relação à definição (o que seriam os problemas e a diferença entre eles e exercícios), finalidades (para que serviriam os problemas) e tipologias (criação de diversos tipos) dos problemas. Utilizaram-se os conceitos de cultura escolar (JULIA, 2001), disciplinas escolares (CHERVEL, 1990) e saber profissional (HOFSTETTER; SCHNEUWLY, 2017) de modo a analisar essas fontes e caracterizar as diferenças acerca dos problemas aritméticos. Observou-se que as modificações ocorridas nos problemas são frutos de discursos que disseminaram inovações pedagógicas e que circularam em determinado tempo. Essas transformações parecem ser decorrentes das tensões entre os diferentes campos disciplinares tais como matemática, ciências da educação e psicologia e que foram apropriadas pela matemática escolar.
O processo histórico da disciplina Matemática como referência para a formação de dirigentes
Authors: Pires Luiz Fernando Rodrigues , Gomes Suzana Santos
Published: August 2021

Este artigo apresenta uma discussão sobre o contexto histórico em que o ensino da Matemática passou a ser utilizado como formação da capacidade de abstração e reflexão, função anteriormente exercida pelo sistema educacional humanista, com o ensino do Grego e do Latim. O século XVIII foi marcado pela revolução industrial, o que contribuiu para o acelerado crescimento das cidades, modificando o perfil de dirigente. Com esse movimento, o ensino humanista entrou em declínio, impulsionando a busca por uma disciplina que poderia substituir a formação dada pelo ensino do Grego e do Latim, algo que possibilitaria a formação do raciocínio lógico, como também a formação de dirigentes e a seletividade da escola (Gramsci, 2001). Nesta visão, optou-se, neste estudo, pela metodologia exploratória cuja coleta de dados se deu pela análise documental, com base em um estudo teórico-bibliográfico. Os resultados indicam que as concepções de abstração e reflexão instituídas atualmente estão relacionadas à aplicação da Matemática à realidade, distante da técnica de pensar indiciada por Gramsci, além da formação de dirigentes estar vinculada mais a concepções mercadológicas do que a real elevação intelectual e moral do cidadão.

Published: August 2021

O presente artigo é parte de uma pesquisa desenvolvida na perspectiva socio-histórica (HOFSTETTER; VALENTE, 2017) que tem investigado a constituição de possíveis saberes para o ofício da docência, em específico aqueles relacionados ao ensino de frações. A partir de um trabalho historiográfico realizado com manuais de George August Büchler, investigamos de que maneira estavam articulados os saberes a ensinar e saberes para ensinar matemática, referentes ao ensino das frações, no período da vaga intuitiva. Concluímos que o autor utiliza as ilustrações em todos os manuais analisados, trabalhando-as como dispositivos didáticos para auxiliar na compreensão do conceito por alunos e professores. Inicia a abordagem do conceito de frações por meio de um diálogo com o leitor. Nesse sentido, apresenta um problema que envolve situações cotidianas, mobilizando os saberes de maneira que o professor possa, ao mesmo tempo, trabalhar ideias diferentes sem necessidade de impor um encadeamento lógico dos conteúdos. O conceito de fração parte do significado que nos lembra hoje parte-todo para o significado de número, sem recorrer a um rigor matemático na escrita. Ainda, indica que o método mais utilizado foi o analítico, que na abordagem de um problema, de modo geral, pode ser um instrumento importante para a estratégia de resolução.

Sabe-se que o estado de Pernambuco sofrerá impactos na precipitação devido ao aumento de CO2 na atmosfera. Na tentativa de contribuir nos prognósticos desses impactos este estudo tem como objetivo desenvolver um modelo que faça prognóstico ou crie cenários futuros para o estado de Pernambuco. Para tanto, foi utilizado o método autorregressivo de médias móveis, ARIMA. O ajuste do modelo foi realizado utilizado a função Bayesian information criterion normalizada. Os resultados mostraram que o modelo desenvolvido apresenta um forte ajuste. O modelo foi melhor ajustado para o Agreste e Oeste do estado. O modelo projeta uma tendência de diminuição da precipitação para o oeste do estado de Pernambuco de aproximadamente 15% abaixo da média histórica até 2027. O modelo projetou precipitações acima da média histórica para o Agreste de Pernambuco, de aproximadamente 17%, até 2027. Conclui-se que ocorrerá com maior frequência anos chuvosos no Agreste de Pernambuco e teremos com maior frequência anos secos no oeste do estado. Na aplicação dos resultados deste estudo e simulação com o modelo SUPer-Sistema de Unidades de Respostas Hidrológicas para Pernambuco conclui-se que ocorrerá mais picos de cheias na bacia do Mundaú até 2027.Palavras-Chave: Cenários, mudanças climáticas, precipitação, recursos hídricos. Development of a Model that Estimates the Impact of Atmospheric CO2 on Precipitation in the State of Pernambuco, using ARIMA ABSTRACTIt is known that the state of Pernambuco will suffer impacts on precipitation due to the increase in CO2 in the atmosphere. In an attempt to contribute to the prognosis of these impacts, this study aims to develop a model that makes a prognosis or creates future scenarios for the state of Pernambuco. For that, the autoregressive method of moving averages, ARIMA, was used. The model adjustment was performed using the normalized Bayesian information criterion function. The results showed that the developed model presents a strong fit. The model was better adjusted for the Agreste and West of the state. The model projects a precipitation decrease trend for the western state of Pernambuco of approximately 15% below the historical average until 2027. The model projected rainfall above the historical average for the Agreste of Pernambuco, of approximately 17%, until 2027. It concludes It is believed that rainy years will occur more frequently in the Agreste region of Pernambuco, and we will have more frequent dry years in the west of the state. In applying the results of this study and simulation with the model SUPER-System of Hydrological Response Units for Pernambuco, it is concluded that there will be more flood peaks in the Mundaú basin until 2027.Keywords: Scenario, climate change, rainfall, water resources.

Uterine wall rupture is a rare yet catastrophic complication of pregnancy with a high mortality rate of both the mother and the fetus. The condition could be classified according to etiology into primary unscarred uterus, and secondary scarred uterus or according to the site of rupture. Our case presented with scarred uterine rupture through a posterolateral injury. The patient had history of 3 previous CS and a D&C procedure. The rupture was complicated by EIV injury. Uterine rupture does not always present with profound manifestations of shock especially in posterior wall rupture and timely management ensures the best possible outcome. Finally, meticulous examination of the anatomically related structures and vessels, and the repair of any associated injuries, is essential.

Для исследования методик оценки влияния ледовой экзарации на подводные трубопроводы проанализирована отечественная и зарубежная нормативно-техническая база в области проектирования, строительства и эксплуатации морских трубопроводных систем, подробно рассмотрены общие подходы к решению данного вопроса. Систематизирован опыт строительства и эксплуатации трубопроводов в условиях замерзающих акваторий, представлены способы их защиты от повреждений в результате дрейфа ледовых образований. Дана оценка характера формирования и особенностей распределения ледово-экзарационных форм по глубине акваторий. Показано, что существующая методология оценки воздействия ледовой экзарации на морские трубопроводы не позволяет в полной мере учесть льдогрунтовое взаимодействие. Установлена целесообразность разработки критериев для определения минимальной безопасной глубины заложения подводных трубопроводов в районах с дрейфующими льдами. Обозначены направления дальнейших исследований механизмов ледового выпахивания, деформаций прилежащего к трубе грунтового массива и поведения заглубленного трубопровода. Полученные результаты позволят дополнить существующую методологию учета воздействия ледовой экзарации на морские трубопроводы, прокладываемые в замерзающих акваториях, с целью обеспечения их безопасности и надежности.

To consider the methods of assessing the impact of ice gouging phenomenon on subsea oil and gas pipelines, the authors analyzed Russian and foreign codes and standards in the field of offshore pipeline systems design, construction and operation, and also considered in detail scientific approaches to investigate this issue. Within the framework of the analysis of peculiarities of offshore pipelines operation in areas with ice gouging, systematization of experience gained from pipeline systems operation in freezing waters was carried out, and methods of pipeline protection from damages caused by drifting ice formations were considered. The assessment of ice induced gouges formation and distribution features is performed. It is shown that the assessment methods presented in current codes and standards to determine the ice gouging impact on marine pipelines do not allow to directly take into account the ice-soil interaction. The feasibility of developing criteria for determining the minimum required burial depth for subsea pipelines in areas with ice gouging is determined. The directions of further research to ensure safe and failure-free operation of subsea pipeline systems in freezing water areas are presented.

The continued relevance of Deep Brain Stimulation for chronic pain
Authors: Sarah Marie Farrell , Tipu Aziz
Published: August 2021

For the millions of patients experiencing chronic pain despite pharmacotherapy, deep brain stimulation (DBS) provides a beacon of hope. Over the past decade the field has shifted away from DBS towards other forms of neuromodulation, particularly spinal cord stimulation (SCS). DBS for pain is still performed, albeit off-label in US and UK, and experiences variable success rates. SCS is an extremely useful tool for the modulation of pain but is limited in its application to specific pain aetiologies. We advocate use of DBS for pain, for patients for whom pharmacology has failed and for whom spinal cord stimulation is inadequate. DBS for chronic pain is at risk of premature neglect. Here we outline how this has come to pass, and in the process argue for the untapped potential for this procedure.

At a time when the Indian economy is in full swing and the growth rate has been declining since 2014, the picture is that Covid 19 has reached the economy by early 2020. Corona, a contagious disease that originated in China, is now spreading all over the world and across India. The disease has infected over 41,94,728 people worldwide to date. And you see it growing steadily. Developed as well as developing countries have not escaped its effects. The result of this Covid 19 is a question mark over human existence. The question is how to sustain the means of survival. The development to date has been hampered by Covid 19. It will create new solutions on how to sustain the development, but it will be difficult and laborious to fill the gaps that have been reached. The lockdown accepted by India has had an impact on the entire economy. In this, many global organizations have indicated that India's growth rate will be 0%.
Young children’s ability to make predictions about novel illnesses

Understanding disease transmission is a complex problem highlighted by the COVID-19 pandemic. These studies test whether 3- to 6-year-old children in the United States use information about social interactions to predict disease transmission. Before and during COVID-19, children predicted illness would spread through close interactions. Older children outperformed younger children, with no associations between task performance and pandemic experience. Children did not predict that being hungry or tired would similarly spread through close interactions. Participants include 196 3—6-year-olds (53% girls, 47% boys; 68% White, 9% Black, 7% Asian, 6% Hispanic or Latinx), with medium-sized effects (d=0.6, ηp2=0.3). These findings suggest that thinking about social interaction supports young children’s predictions about illness, with noted limitations regarding children’s real-world avoidance of disease-spreading behaviors.
Classical and Bayesian Uncertainty Intervals for the Reliability of Multidimensional Scales
Authors: Pfadt Julius M. , van den Bergh Don , moshagen morten
Published: August 2021

The reliability of a multidimensional test instrument is commonly estimated using coefficients 𝜔𝑡 (total) and 𝜔h (hierarchical). However, point estimates for the coefficients are rarely accompanied by uncertainty estimates. In this study, we compare bootstrap and normal-theory confidence intervals. In addition, we develop Bayesian versions of coefficients 𝜔𝑡 and 𝜔h by sampling from a second-order factor model. Results from a comprehensive simulation study show that the studied confidence intervals performed well when the sample size was sufficiently large (𝑁 ≥ 500). The Bayesian estimates performed well across most studied conditions. When the sample size was small and the reliability low, only the bias-corrected and accelerated bootstrap confidence interval approached a satisfactory coverage among all intervals. This study guides on 𝜔𝑡 and 𝜔h confidence intervals and introduces 𝜔𝑡 and 𝜔h credible intervals that are easy to use and come with the benefits of Bayesian parameter estimation.
