A conservative approach to rehabilitate a molar-incisor hypomineralization case
Authors: TEMUDO Rodrigo , NEVES Patricia , VENTURA Irene , LOPES Luísa
Published: May 2022

ABSTRACT Molar incisor hypomineralization is an increasingly common condition in our population. This condition can have great impact on the esthetics, function, and well-being of the child. This paper reports a case of a young patient diagnosed with this condition affecting all the first permanent molars and lower incisors, particularly teeth 31 and 41. The molars were treated with direct resin restorations with cusp coating and the incisors aesthetic was restored with different techniques such as bleaching with sodium hypochlorite, micro-abrasion and resin restorations. This treatment plan aimed to restore the proper teeth function, treat the already existing hypersensitivity and algic complains and to improve the aesthetic of the anterior sector. The presented case shows a conservative approach to deal with the molar incisor hypomineralization condition with satisfactory results after 1-year follow-up.

Authors: Gorayeb-Polacchini Fernanda Salomão , Caldas Heloisa Cristina , Abbud-Filho Mario
Published: May 2022

Resumo Antecedentes: A incidência e a taxa de letalidade da síndrome respiratória aguda grave por coronavírus 2 relatadas em pacientes em diálise crônica são mais elevadas do que na população em geral. Procuramos estudar os desfechos após o diagnóstico da doença por coronavírus 2019 (COVID-19) em pacientes submetidos à hemodiálise crônica (HD) ou diálise peritoneal (DP) em um único centro no Brasil. Métodos: Dos 522 pacientes em diálise avaliados entre 1º de Março de 2020 e 1º de Outubro de 2021, aqueles que apresentaram sintomas ou tiveram histórico de contato próximo com pacientes com COVID-19 foram testados com reação em cadeia da polimerase de transcrição reversa por meio de amostras de esfregaços nasofaríngeos. Resultados: Dos 522 pacientes, 120 foram positivos para infecção por COVID-19, dos quais 86% estavam em HD e 14% no programa de DP. A incidência por 10.000 habitantes foi maior no grupo HD do que no grupo DP (2.423,5 vs. 1.752,5). A mortalidade por 10.000 habitantes (470,5 vs. 927,8) e a taxa de letalidade (19,4 vs. 52,9%, p = 0,005) foram mais elevadas no grupo DP. O grupo DP também apresentou uma maior necessidade de hospitalização, terapia intensiva e ventilação mecânica. Conclusões: Recomendamos cautela ao considerar estratégias de transferência de pacientes do programa de HD para o de DP a fim de minimizar o risco de COVID-19 para pacientes em HD.

Contratos em Sistemas Integrados de Produção Agropecuária
Authors: Stanton Marcia Silva
Published: May 2022

Resumo Os Sistemas Integrados de Produção Agropecuária (SIPAs) têm-se expandido no Brasil devido aos seus benefícios econômicos, ambientais e sociais. Entretanto, apresentam diversos desafios decorrentes da integração de dois sistemas produtivos com distintos processos e infraestrutura. A união de esforços entre produtores é uma alternativa de extrema eficiência, mas requer um adequado regramento da relação jurídica. O presente artigo busca investigar como essa relação tem sido estabelecida para responder se a legislação tem acompanhado a evolução e a dinâmica desse modelo produtivo. A metodologia adotada na investigação foi baseada no estudo de caso, a partir de entrevistas com atores-chave que desenvolvem SIPA em sistema de parceria e arrendamento rural em propriedades localizadas no Rio Grande do Sul. Nessa investigação, verificou-se, por um lado, que o arcabouço jurídico existente fornece as ferramentas necessárias ao adequado regramento da relação contratual, embora algumas atualizações na legislação sejam recomendadas. Por outro lado, concluiu-se que há um desequilíbrio entre as partes no campo da capacitação e da tecnologia. Assim, sugere-se que esse desequilíbrio seja reduzido pela construção de políticas públicas específicas, pois o sucesso de um sistema integrado exige simetria não apenas jurídica, mas também de capital humano, financeiro e tecnológico.
Proibição de discriminação em razão da raça e da origem étnica no contexto europeu, em especial na relação laboral
Authors: Machado Susana Sousa
Published: May 2022

Resumo No presente artigo pretende-se abordar um dos fatores de discriminação proibidos em vários instrumentos normativos europeus: a raça e a origem étnica. Parte-se de uma análise mais geral para a respectiva aplicação da proibição de discriminação em razão da raça e da origem étnica na relação laboral. O estudo é contextualizado à luz de um conjunto de acontecimentos que tem motivado o debate público sobre a temática. É efetuada uma reflexão sobre o conceito de “raça” e “origem étnica” a partir da análise de fontes internacionais e europeias, bem como da jurisprudência do Tribunal de Justiça da União Europeia (TJUE) e do Tribunal Europeu dos Direitos Humanos (TEDH). Busca-se examinar a relação intrínseca entre a proibição de discriminação e a dignidade da pessoa humana, o que exige a proclamação do trabalho digno.
A novel method for deterioration assessment in concrete using colorimetry analysis
Authors: Banerjee Anish , Guru Prathap Reddy V. , Pancharathi Rathish Kumar , Tadepalli Tezeswi
Published: May 2022

Image-based deterioration analysis deals with estimating the correlation between the extent of deterioration in terms of changes in colour profiles of deteriorated surfaces with changes in the residual strength and durability. Analysis was performed on images of cubes of concrete immersed in acid, chloride and sulphate at 5% concentration for a period of 3, 7, 14 and 28 days. The colour profiles of deteriorated surfaces are analysed in CIE-XYZ colour space, and the respective chromaticity diagrams are investigated. The nature of change in the colour profile for respective immersion was investigated, attaining to the sample's absorption rate of the reagent, reagent concentration that was required to initiate chemical reactions and their respective reactivity rates. This study thus enables image-based identification of damage, analytical and non-subjective evaluation of the extent of deterioration and provides an insight into the interrelationship between the extent of deterioration and the performance in terms of strength and durability.

Material and Methods:104 patients who were being treated in university hospital(UH) and 102 patients in State Hospital(SH) because of COPD were included.The difference in approach of physicians and cost analysis between two hospitals were compared
Results and Conslusion:The average age was higher in SH(p=0,01).Comorbities were higher in UH(p<0.001).The number of patients who received nebulizer treatment(p=0,02) in UH and total number of nebulizer medication used was higher in SH(p<0,001).The number of patients for whom intravenous(IV) medication was used and the number of total IV medication used was higher in SH(p<0,001).The total number of IM medication used was higher in UH(p<0,001).The number oral antibiotics used was higher in UH(p<0,001).The penicillins,macrolids,penicillin-macrolids were used more in patients in UH.The cephalosporins and quinolons were used more in SH(p<0,001).Inhaler corticosteroid(ICS)(p<0,001),salbutamol+ipratropiumbromur combination in nebulizer form(p<0,001) and IV teophilin was used in more patients in SH(p=0,01).The use of salbutamol in nebulizer form was more in UH(p<0,001).Spirometry,arterial blood gas analysis(respectively p<0,001,p<0,001),chest radiography was applied more in UH(p=0,02).Total cost(p<0,001),total and daily medication costs was more in SH(p<0,001).Costs other than medication was more in UH(p=0,02).We believe that adherence to the guidelines has a very important effect on cost in patients hospitalized with COPD exacerbation
Review on poultry production, processing, and Utilization in Ethiopia
Authors: Abera Geleta Sime
Published: May 2022

The Ethiopian poultry population (chicken) is projected to be around 56.06 million, with indigenous, hybrid, and foreign breeds accounting for 88.19 percent, 6.45 percent, and 5.36 percent of the total poultry, respectively. Ethiopian poultry farming methods are typically low-productivity subsistence systems. This paper will now collect data on chicken kinds used for meat and egg production, as well as their use, difficulties, and potential in Ethiopian poultry productivity. It also discusses Ethiopian poultry production methods, their contributions, and challenges such as feed shortages, predators, disease, veterinary service, health management, marketing, genetic quality (breed), and Extension service issues. However, information covers both the past and the present; production options include training and extension services, veterinary services, market access, financial services, and the requirement for limited space and inputs. As a result, certain actions must be taken immediately to alleviate these limits and boost the poultry’s production potential.
Effects of photo-selective netting in Summer Beefsteak Tomato (Solanum lycopersicum L.) cultivation on the environmental conditions under nets as well as growth and yield
Authors: Kuei-Yuan Chang , Jun-Cheng Dai , Yu Yu Sung
Published: May 2022

Located in a subtropical zone, Taiwan has intense summer sunlight that affects beefsteak tomato cultivation. In this study, beefsteak tomatoes were grown net-house under photo-selective netting of different colors to investigate netting performance. A significantly higher photosynthetic photon flux density (PPFD) was observed under the 24-mesh white (W24) and 24-mesh pink (H24) netting. A difference between the four net-house was only observed for wavelengths of 500–599nm. In 32-mesh blue (B32), the red to blue (R/B) and red to far-red (R/FR) ratios were significantly lower across canopies. The photosynthetic capacity of photosystem II of leaves in W24 was the lowest among the four treatments. In all four, fruit growth was relatively low under the impact of high temperatures, with the lowest single fruit weight and the smallest number of fruits per plant observed in W24. In H24 and 24-mesh pink (HH24), the yield per plant was significantly higher. Significantly fewer whiteflies were observed in the netting houses in H24, HH24, and B32 than in W24. However, the netting still failed to prevent high temperatures at noon. In H24 and HH24, the amount of light retained in the canopies was greater, the photosynthesis capacity was unchanged, the fruit yield was greater and the number of whiteflies in the netting houses was significantly lower. Therefore, pink netting is recommended for beefsteak tomato cultivation.

A precise gene delivery approach for human induced pluripotent stem cells using Cas9 RNP and recombinant AAV6 vectors v2
Authors: Chupradit Koollawat
Published: May 2022

Genome editing in human induced pluripotent stem cells (hiPSCs) offers a potential tool for studying gene functions in disease models and correcting genetic mutations for cell-based therapy. Precise transgene insertion in hiPSCs represents a significant challenge. In the past decade, viral transduction has been widely used due to its high transduction efficiency; however, it can result in random transgene integration and variable transgene copy numbers. Non-viral-based strategies are generally safer but limited by their low transfection efficiency in hiPSCs. Recently, genome engineering using adeno-associated virus (AAV) vectors has emerged as a promising gene delivery approach due to AAVs’ low immunogenicity, toxicity, and ability to infect a broad range of cells. The following protocol describes the workflow for genome editing in hiPSCs using CRISPR/Cas9 ribonucleoproteins (RNPs) combined with the recombinant AAV serotype 6 (AAV6) donor vectors to introduce a gene of interest (GOI) fused with mCherry fluorescent reporter gene into the AAVS1 safe harbor site. This approach leads to efficient transgene insertion and is applicable to precise genome editing of hiPSCs or other types of stem cells for research purposes.

Osteosynthesis and total hip replacement in femoral neck fractures
Authors: Ankin N. L.
Published: May 2022

Three hundred thirty nine patients with femoral neck fractures were operated on during the period from 1990 to 1994. Most of operations were performed within 48-72 hours after trauma. 235 patients with an average age of 70 years were treated by osteosynthesis using plates, srews, rods, DHS. 104 patients with average age of 76 years underwent total hip replacement procedures using Moore, Baitmann, Muller, Spotorno (Etalon, Kiev) implants. 17 patients (5%) died. Out of them 10 patients died after total hip replacement, 4 patients - after closed osteosynthesis and 3 patients - after open osteosynthesis. In 96 patients with osteosynthesis results were evaluated after 1-2 years. Good results were in 78% of them, satisfactory - in 15,7% and bad - in 6,3%. Author supports as early as possible operative treatment of patients with femoral neck fracture and prefers an open osteosynthesis with spongy screws. Advantages of closed osteosynthesis with DHS is noted too.
Criteria and methods for assessing the damaging effect of impulsive dynamic factors (literature review and own data)
Authors: Bogdanov G. N. , Neshev N. I. , Shaposhnikov Y. G.
Published: May 2022

Among the traumatogenic factors of various nature, a special place is occupied by a group of impulse dynamic effects caused by short-term high-energy effectors, the damaging effect of which is associated with the rapid transfer of a large amount of mechanical energy to tissues and organs. The development of experimental methods for determining the nature of energy distribution in individual anatomical and morphological structures and diagnosing the severity of the lesion is a very urgent problem that is of undoubted interest to a wide range of doctors, and especially traumatologists.
Site Amplification at High Spatial Resolution from Combined Ambient Noise and Earthquake Recordings in Sion, Switzerland
Authors: Perron Vincent , Bergamo Paolo , Fäh Donat
Published: May 2022

Earthquake site effects have a major impact on the seismic hazard. However, evaluating the site response over a broad frequency range and with a high spatial resolution remains difficult. Therefore, there is a high demand from the engineering seismology community in having cost-effective and reliable approaches to evaluate the site response. Empirical site effect assessment has shown good reliability up to high frequencies but relies on earthquake recordings that require long station deployments. In contrast, seismic ambient noise can be rapidly recorded anywhere at any time. The hybrid standard spectral ratio (SSRh) combines both the spectral ratio from earthquake recordings at a few sites and the spectral ratio from ambient noise recordings at many sites from short duration deployments. The objective of our study is to evaluate the applicability of the SSRh to a large urban area. Our studied area is the Rhône valley around the city of Sion (Switzerland), which is prone to complex 2D and 3D site effects in a broad frequency range caused by the soft, thick, and variable sedimentary deposit of the Rhône river. We benefit from four permanent and five long-term seismic stations present in the area, and we performed 299 short ambient noise measurements on a regular 300 m side grid. At the permanent stations, we find good agreement between the SSRh and the empirical amplification function estimates using earthquake observations, and we observe a good stability of the SSRh over time, frequency, and space, despite the strong variability of the ambient noise. Based on that, we estimate the SSRh for every ambient noise recording point in the area to compute a high-resolution amplification model and subsequently a site-specific seismic hazard model for the Sion area. Our models are in good agreement with the geological information.
Yield Estimation and Event Discrimination of the 4 August 2020 Beirut Chemical Explosion
Authors: Zhang Lei , Zhao Lian-Feng , Xie Xiao-Bi , He Xi , Yao Zhen-Xing
Published: May 2022

We investigate the 4 August 2020 Beirut accidental chemical explosion based on regional seismic data recorded at both on- and off-shore stations. The Lg-wave body-wave magnitude is mb(Lg)=3.30±0.46 for the Beirut explosion. The explosive yield obtained using an empirical magnitude-yield relation based on a fully buried explosion source model is only 0.112 kt. Alternatively, the yield estimated using an empirical relation between the yield and crater size is 1.22 kt, with the uncertainties between 0.48 and 2.3 kt. The latter is closer to reality. The P/S spectral amplitude ratios, including Pg/Lg, Pn/Lg, and Pn/Sn, are calculated for the Beirut explosion and nearby natural earthquakes. We find the P/S spectral ratios are effective in discriminating the explosion from earthquakes in the Northwestern Arabia plate. By comparing the spectral ratios of large open-pit explosions, including the Beirut, Xiangshui, and Tianjin explosions, with those from historical nuclear explosions, buried small chemical explosions, and natural earthquakes, we further investigate the detailed differences of network-averaged P/S spectral ratios between different source types.
Энергетическая политика ЕС и ее движущие силы
Authors: Боровский Юрий , Шишкина Ольга
Published: May 2022

Энергетический кризис, начавшийся в Европейском союзе осенью 2021 г. и обострившийся в марте 2022 г., в очередной раз продемонстрировал, насколько остро стоит проблема стабильного и доступного энергоснабжения. Имевшиеся в распоряжении ЕС механизмы кризисного реагирования не позволили ему оперативно ответить на ситуацию, хотя новый скачок цен на энергоресурсы был вызван, по сути, “старыми” причинами, знакомыми ему по событиям 1970-1980-х и середины 2000-х годов – дефицитом ресурсов и политической нестабильностью в регионе, откуда ведутся основные поставки. Новым стало то, что парадоксальным образом энергетическая политика ЕС, которая должна была не допустить кризиса или, как минимум, сгладить его, напротив, внесла свою лепту в усугубление положения. В этом контексте авторы прослеживают, какие движущие силы стоят за развитием энергетической политики стран – участниц евроинтеграции и, исходя из этого, поясняют, почему, имея хронический дефицит энергоресурсов, ЕС планомерно отказывался от долгосрочных контрактов с поставщиками и призывал страны-члены снижать долю атомной энергии, а в условиях постпандемийного роста спроса на энергоресурсы на мировых рынках и небывалого увеличения цен на них предпринял выглядящие нелогичными шаги: отказался от запуска построенного газопровода “Северный поток – 2”, был готов закупать дорогостоящий СПГ у альтернативных поставщиков и продолжать оплачивать развитие ненадежных и дорогостоящих возобновляемых источников энергии в условиях, когда цена газа на спотовых биржах достигала рекордных показателей. Для выявления движущих сил применяются основополагающие теории международных отношений (реализм, либерализм, социальный конструктивизм, неомарксизм), а также теории европейской интеграции (межправительственный подход, неофункционализм, институционализм, теория коммуникации), позволяющие взглянуть на процессы внутри интеграционного объединения и принять во внимание наднациональный фактор при принятии решений. Рациональный подход при определении движущих сил и их действий по достижению целей энергетической политики, предлагаемый реализмом и либерализмом, а также неофункционализмом и некоторыми другими теориями, не находит своего подтверждения в практических шагах, предпринимаемых ЕС в сфере энергетики в момент кризиса 2021-2022 гг. Теории, берущие за основу социальный подход – социальный конструктивизм, неомарксизм и др., – дают более логичное объяснение решений, принимаемых в ЕС.
К вопросу о продуктивности санкций в отношении КНДР
Authors: Коргун Ирина , Толорая Георгий
Published: May 2022

Ужесточение международного санкционного режима в отношении КНДР произошло в декабре 2017 г., в результате предложенного в ООН США и их союзниками пакета мер под запретом оказалось 90% экспорта и существенная часть импорта страны. Но это не принесло результатов в вопросе сворачивания ракетно-ядерной программы КНДР. Отсутствие прогресса в диалоге с элитами КНДР и ее высокая степень адаптивности к ситуации ставят вопрос об эффективности санкций. Авторы статьи анализируют непредвиденные последствия санкций, которые выражаются в росте объема нелегальных операций КНДР и диверсификации их видов. На полученных результатах демонстрируется, что, хотя санкции негативно воздействуют на экономику и социальную сферу КНДР, они не расширяют поле для компромисса и в долгосрочной перспективе подрывают дипломатический процесс. В период действия санкций наблюдается рост нестабильности на Корейском полуострове в силу дальнейшего развития военной программы Пхеньяна и разрастания его нелегальной деятельности. Продолжающаяся глобализация сектора информационных технологий открывает новые возможности режиму для самофинансирования. Делается вывод, что, несмотря на очевидную контрподуктивность санкций, их применение будет расширяться и усложняться, вовлекая новые сферы и все большее число участников из частного сектора и осложняя мировую политическую обстановку.

En el presente artículo de investigación se identifican los beneficios tributarios de carácter nacional, dentro de los cuales se encuentran los ingresos no constitutivos de renta ni ganancia ocasional, las deducciones, las rentas exentas, los descuentos tributarios y  tarifas reducidas, entre otros; se clasifican las PYMES  de acuerdo con las actividades económicas y las normas que las regulan; y por último; se analiza la implementación de los beneficios tributarios de carácter nacional aplicados por las PYMES del departamento del Quindío. La investigación se realiza bajo el método descriptivo utilizando un enfoque mixto, considerando una parte cualitativa dado que existe una referenciación conceptual, teórica y documental; y otra parte cuantitativa, por el uso de métodos estadísticos y tabulación de datos para la presentación de los resultados, además, se utiliza como instrumento de recolección de la información una encuesta estructurada por secciones de acuerdo al tipo de beneficio tributario. Los resultados indican que hay varios beneficios tributarios que las PYMES del departamento del Quindío no utilizan, ya sea por desconocimiento o porque no cumplen los requisitos para acceder a ellos. Además, se evidencia que los empresarios utilizan los beneficios tributarios más conocidos, como los otorgados en el régimen simple de tributación, al considerar que les permite reducir el pago de impuestos y generar ahorro para invertir, contratar más empleados y crecer en el mercado.
Acuerdo de Paz y tenencia de la tierra en Colombia. Visiones y retos de un país en disputa

Published: May 2022

En Colombia, los problemas agrarios y las políticas de desarrollo rural han sido las causas principales del conflicto social y armado, agudizando las condiciones de desigualdad y pobreza. El Acuerdo de Paz firmado en 2016 entre el Gobierno colombiano y las FARC-EP, expresa el encuentro de dos visiones de país en disputa, en cuanto a las soluciones de las problemáticas agrarias. El objetivo de este artículo es presentar las visiones y retos que están aún sin resolver en torno a la Reforma Rural Integral. Se empleó una metodología cualitativa descriptiva con enfoque histórico hermenéutico. Se encontró que es prácticamente imposible llevar a cabo el proceso de acceso y formalización de la tierra y tener actualizado el catastro multipropósito en el corto plazo; y, sin embargo. es una necesidad imperiosa para el acceso y formalización a la propiedad de la tierra por los campesinos colombianos. En conclusión, es preciso que la institucionalidad disponga de todas las herramientas necesarias para implementar y garantizar que se efectúe de manera óptima una Reforma Rural Integral; y que además sea efectiva la participación de las distintas comunidades rurales en la administración de las políticas que les afectan, a partir del reconocimiento de la identidad campesina

El presente artículo busca develar que la renta básica universal, lejos de ser una utopía, se encuentra incrustada en la realidad. En este sentido, se indagará sobre los orígenes de la idea, es decir, su formación desde lo utópico, por medio de un estudio bibliográfico e historiográfico, para luego mostrar cómo, a través de los proyectos piloto de instauración de ingresos básicos incondicionales en países como Namibia, India y Kenia, se logró obtener evidencia empírica que da cuenta de sus beneficios como herramienta para hacer frente a las necesidades de la pobreza y precariedad. Necesidades que, con la llegada de la pandemia COVID-19, volvieron indiscutible su instauración. El artículo presenta una revisión crítica de la literatura marxista y feminista-marxista sobre el trabajo doméstico no remunerado. Se organizó en tres grandes controversias: el concepto y la naturaleza del trabajo doméstico no remunerado, el rol económico del trabajo doméstico en el capitalismo y la desigual distribución del trabajo doméstico no remunerado dentro de los hogares. Se hizo énfasis en la literatura reciente, debates y autores contemporáneos, aunque también se abordaron algunos trabajos clásicos relevantes. En cada controversia, se exponen críticamente las ideas, escuelas y autores/as principales, mostrando sus aportaciones, limitaciones y contradicciones. Al finalizar, se presentan las perspectivas del debate.
TikTok and tics: the possible role of social media in the exacerbation of tics during the COVID lockdown

Published: May 2022

Over the past year, many cases with newly onset or significantly exacerbated tic disorders were observed worldwide, where some aspects of the clinical presentation or the symptomatology were atypical for established tic diagnoses. Our purpose was to describe the atypical cases and raise relevant diagnostic issues. Consecutive cases with atypical tic presentations were documented. Five atypical tic cases are described. These cases shared some common characteristics, most notably the fact that all of them had been exposed to online presentation of ticking behaviour on social media platforms prior to the de novo development or exacerbation of their tics. Even though the order of events suggests causality and therefore the diagnosis of a functional tic disorder, unambiguous criteria for classifying atypical tics as functional symptoms are lacking. Differentiating neurodevelopmental and functional tics in childhood is currently problematic. Based on the currently unresolved issues in differential diagnosis, the importance of watchful waiting and behavioural interventions is highlighted to avoid unwarranted pharmacotherapy.

Published: May 2022

Presently, C++ programming has been taught in many universities around the world as the first object-oriented programming language for undergraduate students to start studying programming concepts and computer architecture. However, many of them may struggle in studying C++ programming due to the nature in the formal language. Thus, hands-on self-study tools can be effective. In previous, we have developed Java programming learning assistant system (JPLAS) for assisting self-study of Java programming. JPLAS offers the value trace problem (VTP) for novice students to study Java programming through code reading study. In a VTP instance, actual values of important variable or standard output messages in a given source code are questioned, where the correctness of each answer is checked through string matching. In this paper, we investigate the effectiveness of VTP for hands-on self-study of C++ programming by novice students. We generated 37 VTP instances for basic grammar concepts using source codes in textbooks or websites for C++ programming, and asked 46 students in three universities in three countries to solve them using the answer interface for JPLAS. The results suggest that most of the students are satisfactory, but some students need cares at early programming study stage.

Background: Insulin resistance (IR) is a metabolic state characterized by a decrease in cellular ability to respond to insulin signaling, which contribute to pathophysiological mechanism in the development of all metabolic complication of polycystic ovary syndrome (PCOS). The aim of the study was to match categorized values of patient’s biochemical predisposing factors for polycystic ovaries such as insulin with change in follicular sizes as determined by sonography following CLOMID inducement therapy.Methods: This experimental study was carried out in Anambra State, Nigeria from June 2018 to May 2021. Those included in the study were women of child bearing age (18 to 45 years) for both groups. The ultrasound examinations and insulin levels measurements were performed on each subject and data such as follicular sizes, insulin levels before and after treatment were recorded. Obtained data were analyzed using both descriptive and inferential statistical tools.Results: There were no statistically significant mean differences in the insulin levels (t=1.16, p=0.81) and maximal follicular size (t=0.39, p=0.70) of women with and without polycystic ovary who had successful and failed ovulation before the clomid treatment. Both the insulin level (t=2.85, p<0.01) and follicular size (t=4.88, p<0.01) showed statistically significant mean differences. There was significant difference in insulin (F=7.55, p<0.01), with the control having the lowest insulin concentration.Conclusions: There were statistically significant mean differences in the insulin level and follicular size in women with polycystic ovary after clomid treatment. Therefore, clomiphene citrate inducement triggers increase in serum concentration of insulin.

Background: Non-alcoholic fatty pancreas disease (NAFPD) is an emerging clinical entity. NAFPD is characterised by excessive fat deposition in the pancreas in the absence of alcohol consumption. Recent studies suggest that NAFPD might be associated with beta cell dysfunction, insulin resistance and inflammation which might lead to development of diabetes. NAFPD might be used as an initial indicator of glucometabolic disturbances and identify the patients with prediabetes.Methods: This was a cross sectional study in which the glycemic status of 50 patients with NAFPD with ultrasonographic evidence of increased echogenicity of pancreas was assessed and association between glycemic variability and NAFPD was determined. The patients were also assessed for the ultrasonographic evidence of fatty liver.Results: Pre-diabetes was noted in 32% subjects while diabetes was noted in 20% subjects. Thus, 52% patients with NAFPD had abnormal glycemic status. The 48% subjects i.e., 24 patients had normoglycemia. The presence of fatty liver was statistically significant in normoglycemia and diabetes mellitus with p=0.001 and 0.045 respectively. No statistically significant association was noted between fatty liver and prediabetes with p=0.175. No causal relationship was seen between fatty liver and glycemic variability in patients with NAFPD.Conclusions: NAFPD is associated with impaired glycemic status. It is also seen frequently with fatty liver. Its early detection may help to identify the patients with prediabetes who may benefit from timely introduction of interventions to reduce the rising morbidity and mortality due to diabetes mellitus.

Due to the novel nature of oral nicotine pouches, limited studies have been conducted on the usage of these products in real-world settings. Consumption patterns and use behaviour of current nicotine pouch users need to be investigated to monitor the use and support the assessment of reduced risk products. Here we report the findings of an online survey completed by 550 participants across Sweden, Denmark, Germany and Switzerland who were current nicotine pouch users. The key areas of research were oral nicotine use history, mouth hold duration, nicotine strength, average daily consumption (ADC) and flavour preferences. Across all countries, most participants used oral nicotine pouches for 12 months or less. Longer use of nicotine pouches was reported in Sweden. Pouches containing 6‒15 mg nicotine were used most frequently in all countries, and particularly 11‒15 mg pouches in Sweden and Denmark. Average ADC across all countries was 1-5 pouches, closely followed by 6-10 pouches in Sweden and Denmark. Menthol was the most preferred flavour in all countries, followed by fruity and other food flavours. These findings reflect the differing product use patterns across nascent and mature markets as well as the need to investigate how different experience of product types can affect the use of new categories. Further research is required with a larger sample over time to understand product use patterns more clearly, including transition from and into other product categories.

Introducción: El sueño es un estado fisiológico-rítmico que cursa con pérdida de conciencia y capacidad de respuesta. Durante este se llevan a cabo procesos imprescindibles para el aprendizaje y el metabolismo, por lo que cobra relevancia conservar una adecuada calidad del mismo. Objetivo: Describir la calidad del sueño de los estudiantes de medicina de la Universidad Andrés Bello sede Concepción, durante el primer semestre del año 2019. Métodos: Se realizó un estudio descriptivo de corte transversal con 147 estudiantes de primer a cuarto año de la carrera de medicina de la Universidad Andrés Bello sede Concepción. Los datos fueron levantados mediante el Índice de la Calidad de Sueño de Pittsburgh --ICSP--, y posteriormente procesados con el software IBM Statistics SPSS v.22. Resultados: El 91,8% de los estudiantes presentaron mala calidad de sueño (ICSP>5), con una puntuación promedio de 8,4. Los componentes con mayor variabilidad entre los cursos fueron la duración (p<0,01) y las perturbaciones del sueño (p<0,02). Por su parte, los estudiantes que trabajaban presentaron mayor presencia de perturbaciones del sueño en comparación con aquellos que solo se dedicaban a sus estudios (p=0,03). Conclusiones: Los estudiantes de la carrera de medicina de la Universidad Andrés Bello, sede Concepción, presentaron una mala calidad del sueño. Esto podría ser atribuido a la alta exigencia académica y/o a la carga horaria utilizada en clases teóricas y prácticas, y empeoraría al agregar exigencias adicionales como tener que trabajar durante los estudios.

Introducción: La eritrosedimentación es una medida indirecta de inflamación, se eleva ante un aumento de proteínas (reactantes de fase aguda) durante trastornos inflamatorios, un valor extremadamente elevado (≥100mm/hora) tiene una alta especificidad para el diagnóstico de enfermedades infecciosas, neoplásicas y autoinmunes. Objetivo: Caracterizar a los pacientes hospitalizados con una elevación extrema de la eritrosedimentación, y explorar su asociación con otros factores determinantes. Métodos: Estudio descriptivo de corte transversal. Se incluyeron pacientes mayores de 18 años, con eritrosedimentación extrema, internados en el Hospital Pablo Tobón Uribe de la ciudad de Medellín, desde Noviembre de 2016 hasta Junio de 2018. Resultados: Se seleccionaron 1007 pacientes de la base de datos del hospital, las infecciones, con 743 (73,8%) afectados, fueron el principal diagnóstico relacionado. Se evidenció una correlación negativa de la eritrosedimentación con la hemoglobina -0.092(-0.155 a -0.029) p <0.01 y con el hematocrito -0.087(-0.150 a -0.024) p 0.01, y una positiva significativa débil con la PCR 0.080 (0.014 a 0.146) p 0.02. Discusión: Acorde a otros estudios, las infecciones representaron el primer grupo de elevación extrema, contrario a otro estudio se evidenció una correlación directa, débil y estadísticamente significativa entre la Proteina C reactiva y la eritrosedimentación extremadamente elevada. Conclusión: Las infecciones fueron el principal grupo de enfermedades con eritrosedimentación extrema, se evidenció una correlación inversa entre la eritrosedimentación con la hemoglobina y el hematocrito, y una correlación positiva débil con la proteína C reactiva.

Authors: Tabanfar Sara , Sobhani Seyvan
Published: May 2022

Background: Due to the Covid-19 pandemic and the increase in anxiety in the community, this study aims to investigate the relationship between anxiety symptoms and demographic characteristics of administrative staff during the Covid-19 pandemic. Methods: We selected 193 Administrative staff in Qazvin to participate in a cross-sectional descriptive study, using a multi-stage sampling method. Data collection tools included a demographic information questionnaire and the Corona Disease Anxiety Scale (CDAS). Data were analyzed using SPSS software, independent t-test, ANOVA, and Pearson correlation coefficient. The significance level was considered to be 0.05. Results: The mean age of participants was 33.61±8.3. 62.6% were female and 75.2% were married. Anxiety score with a mean and standard deviation of 24.88±7.52 was evaluated to be moderate. There was a significant positive correlation between anxiety score and age (P= 0.007 and r= 0.267), and work experience (P= 0.003 and r= 0.313). Participants with a family member over the age of 65, or a member with a chronic illness, had significantly higher mean anxiety scores than other participants. Conclusion: Employees' anxiety in this study was assessed as moderate. To bring anxiety to a low level and increase the general health of individuals, it is suggested that managers and heads of departments consider programs to reduce the anxiety of employees. By reducing anxiety scores, they can increase the productivity of these people.

Authors: Sobhani Seyvan , Tabanfar Sara
Published: May 2022

Background: Due to the prevalence of the Covid-19 virus and its effects on people's lives and the lack of studies on non-health workers, the present study was conducted to evaluate Covid-19 anxiety and its relationship with sleep quality among industrial workers. Methods: The research method was descriptive and cross-sectional. We selected 212 individuals using random sampling. Data were collected using a demographic information questionnaire, the Corona Disease Anxiety Scale (CDAS), and the Pittsburgh Sleep Quality Index (PSQI). For data analysis, Pearson correlation test, independent t-test, and ANOVA were used in SPSS software version 24. Results: The mean age of participants was 33.27±6.6, 78.8% of whom were male, and 79.3% were married. The CDAS and PSQI score's mean and standard deviation were 11.60±8.2 and 5.37±1.7, respectively. There was a significant relationship between CDAS scores and age (P= 0.008) and work experience (P= 0.005). Also, a significant relationship was observed between PSQI score and age (P= 0.032) and work experience (P= 0.009). There was a significant correlation between CDAS and PSQI scores (r= 0.341 and P= 0.007). People with lower levels of education showed high anxiety scores and poor sleep quality. Conclusion: According to the findings of this study, the authors concluded that by reducing anxiety, the quality of sleep could be increased. Therefore, to reduce anxiety and increase the quality of sleep and employee productivity, the researchers suggest that factory managers identify and eliminate the causes of anxiety by establishing continuous and regular mental health training.
