Pope Gregory the Great’s Arguments Against the Ecumenical Title of the Patriarch of Constantinople: Analysis of the Letters from 595
Authors:   St. Tikhon’s Orthodox University, Migalnikov Aleksei
Published: January 2022

Introduction. At the end of the sixth century a dispute broke out between the popes and the patriarchs of Constantinople – first of all, between pope Gregory I the Great (590–604) and patriarch John IV the Faster (582–595) – over the epithet “Ecumenical”, which appeared in the title of John of Constantinople. This dispute is quite widely represented in the scientific literature, but since researchers almost always pay attention to this topic in general, their papers often miss many nuances contained in the texts of the letters of pope Gregory. Methods. This article attempts a detailed analysis of the first series of letters of pope Gregory dedicated to the dispute and related to 595. These are letters to emperor Maurice (582–602), empress Constantina, the patriarch John IV of Constantinople, and the papal apocrisiary in Constantinople, deacon Sabinianus. The purpose of this study is to reconstruct pope Gregory’s argumentation system against the use of the Ecumenical title. Analysis. The author identifies several types of arguments that pope Gregory puts forward in his polemic against the title: canonical, biblical, dogmatic, ecclesiastical, political, pastoral and ascetic. Results. The article shows, on the one hand, what the letters have in common, and on the other, how the arguments of the pope vary depending on the recipient. Generally, pope Gregory expresses a sharply negative attitude to the title, and many researchers tend to see this fact as a contradiction to the concept of papal primacy, as it developed in a later period. Basing on the significant differences in argumentation between the letters to the emperor, the empress and the patriarch John – with the same purpose of all the messages – the article makes a conclusion about the care with which pope Gregory selects arguments. This can serve as one of the indirect indicators of the high importance of the dispute over the Ecumenical title for him, and also characterizes his perception of the idea of Church power in general.
The Time of Patriarchs Peter IV and Damian As the Nodal Point of the Genesis of the Coptic Church: Problems and Proposed Solutions
Authors:   Centre for Egyptological Studies of the Russian Academy of Sciences, Voytenko Anton
Published: January 2022

Introduction. The article examines a recently put forward hypothesis that the time of the Coptic Church’s final genesis was the period of the Alexandrian anti-Chalcedonian Patriarchs Peter IV (576–578) and Damian (578–607). Methods. A comparative research method and factor analysis are used. The main research task is to identify all the factors that contributed to the making of full-fledged ecclesiastical structures by the Theodosians (one of the trends of the Egyptian Miaphysites), and a correlation of these factors with each other to single out the main of them. Analysis. The successful establishment of the Miaphysites (Theodosian) episcopate resulted from the configuration of objective and subjective factors. Objective factors include the following: the weakening of control by the central authorities over the structures of the Miaphysites after Justinian I (482/483–565), the increasing regionalization of the empire and the strengthening of the role of local elites in the provinces, the growing importance of the Coptic language in secular and clerical office work. Subjective factors include the victory of the Miaphysite Patriarch Peter IV over his rival Theodore and the appearance of Damian as Peter’s successor. Results. On the whole, the proposed hypothesis quite thoroughly explains the emergence of the Coptic Church during the period. However, it has several disadvantages, which open up a number of prospects for further researches. Firstly, there is almost no explanation for the success of Damian’s personnel policy. Secondly, insufficient attention was paid to the Egyptian anti-Chalcedonian monasticism. From the author’s point of view, Egyptian Miaphysite monks, suffering from the pressure of the central and local authorities after the Chalcedonian schism, managed to establish an effective network functioned as a “rhizome”, on which the episcopate risen during Peter’s and Damian’s time relied primarily in rebuilding stable ecclesiastical structures in Egypt.
The Concept of “Miracle in a Fiery Furnace” in Byzantium and Its Later Reminiscences
Authors:   State Museum-Preserve “Tauric Chersonesos”, Romensky Alexandr
Published: January 2022

Introduction. The article discusses the motive of a “miracle in a fiery furnace”, based on the story of the Three Holy Children in the Book of Daniel. Methods. The study provides a comparative analysis of the Biblical topos about the trial by fire in Byzantine, Western European and Eastern sources. A semiotic approach of textual study is used. Analysis. In Byzantine hagiography and hymnography, the plot of the “Three Holy Children” was interpreted as a prototype of the Incarnation, so, the sacred situation was reproduced in new historical conditions. In the Lives of Bishops of Cherson, the plot about miracle in the furnace is used for construction the local sacred history. Similar motives are found in the narratives about the baptism of Rus, such as Vita Basilii (the fifth book of Theophanes Continuatus), Vita beati Romualdi by Petrus Damiani, Historia de predicatione episcopi Brunonis. In narrative about conversion of Özbeg Khan to Islam, literary plot was connected with shamanistic representations about the holy fire. Results. The Biblical topos of the “fiery furnace” underwent a semantic transformation within the framework of various discourses. It was used in Byzantine texts for constructing the Christian Identity, while was enhanced by Turkic mythology in Muslim tradition.
Finger Ring Amulets with the Image of the Holy Rider of the 7th Century from the Crimea
Authors:   Institute of Archaeology of Crimea of the Russian Academy of Sciences, Khairedinova Elzara
Published: January 2022

Introduction. The group of jewelry with Christian symbols that existed in the Crimea in the early Middle Ages includes cast bronze rings, on a flat shield of which the image of a holy rider with a cross in his hands is engraved. The rings were found in the South-West Crimea in the burial grounds near the village of Luchistoe, Skalistoe and EskiKermen, as well as in Kerch at the early medieval necropolis of the Bosporus, in the burials of the 7th century. Methods. For the attribution of published products, a circle of analogies is identified, findings from the territory of the Eastern Roman Empire are analyzed. The iconography of the holy rider is compared on various subjects. In the Crimea, three of the published finger rings were found in in situ burials, as part of a closed complex, together with tools with a narrow dating, which makes it possible to clarify the time of existence of this type of products in the region and to determine the method of wearing it. Analysis. The plot depicted on the finger rings has an undeniable resemblance to the scene of the solemn entry of Jesus Christ into Jerusalem, described in all four Gospels and well known from the numerous pictorial monuments of the early medieval period. The iconography of that scene originated in the era of Constantine the Great, under the influence of imperial art and in many ways corresponded to the Triumphal entry of the emperor to Rome or any large city of the empire. The image of Christ the rider on the Crimean finger rings belongs to the iconographic type, which became widespread in the 6th–7th centuries, mainly in Egypt, the Syro-Palestinian region and Asia Minor. The quality of execution of the published rings from the Crimea allows us to speak about their local production. Byzantine products that came to the peninsula thanks to stable trade relations with the empire or were brought by pilgrims from holy places served as models for the Crimean artisans. In the minds of ancient Christians, the image of Christ the rider had a powerful protective power. Placed on the shield of the ring, it endowed the decoration with the properties of an amulet, protecting the person wearing it from all troubles. The rings originating from Crimea belonged to a teenage girl and young women who wore them on their hands – on the right index or ring finger, or in special belt bags, in which, in addition to utilitarian items, various amulets were also put. Results. The study of rings makes it possible not only to expand knowledge about jewelry that existed in the early medieval times, but also to replenish our information about the daily life of the Christian population of the early medieval Crimea.
Ceramics of the Middle East from the Excavation of the Eski-Kermen Site

Published: January 2022

Introduction. Three exemplars of Middle Eastern fritware of the 12th–13th centuries, which were first discovered on the territory of a Byzantine town on the Eski-Kermen plateau during the excavations in 2018 and 2019, are presented in the article. They belong to the three different decorative groups, which had not been found in the Crimea before and are rather rare in the archaeological sites of Eastern Europe in general. Methods. The methods of archaeology and art history are involved in the study. First of all these are a stratigraphic method for the chronology of the contexts and artifacts, as well as a comparative method to identify the origin of finds. Analysis. The vessels under study belong to different decorative and stylistic groups of oriental ceramics. The plate and one jug find parallels among the products of the Raqqa workshops from the first half to mid 12th century and late 12th to mid 13th century. Another jug most likely comes from Iran and can be dated to the 12th–13th centuries. Results. These kinds of vessels were not very common outside the region of their production. At least we have very little information about these facts now. So the finds from Eski-Kermen are important for expanding the area of distribution of these types of fritwares. In addition, their presence in a small provincial Byzantine town indicates the residence there in the 12th–13th centuries of the local elites, who could get and own such expensive and quite rare things.
South African teachers’ experiences of continuous professional teacher development: Connections and disconnections
Authors: Van der Merwe-Muller Lorna , Dasoo Nazreen
Published: January 2022

In this article we present the findings of an investigation on how primary school teachers at 3 independent primary schools in Johannesburg experienced continuous professional teacher development (CPTD). There is a wealth of literature available on planning, organising and implementing effective CPTD. Such literature also highlights the importance of applying adult learning principles in CPTD contexts in order to promote teachers’ learning and development and in turn contributing to a positive effect on learning in the classroom. Exploring the value and usefulness of adult learning principles in CPTD can enhance primary school teachers’ learning opportunities to update their knowledge and skills. Effective CPTD is important in South Africa as there is an urgent need to improve literacy and numeracy levels across primary education levels. Using qualitative data, we explore teachers’ perspectives on how they learn and develop effectively, and what hinders their own learning and CPTD. Data collection methods included interviews, open-ended questionnaires, observations and document analysis. Fifteen primary school teachers, 3 primary school principals and 4 adult/teacher trainers participated in this investigation. A major finding of this research suggests that adult learning principles such as community of practice (CoP) are often omitted from CPTD practices. Thus, a disparity exists between literature on effective CPTD practice as compared to the everyday CPTD experiences of teachers. With this article we aim to contribute to current literature about teachers’ experiences of CPTD and propose suggestions for planning, organising and implementing CPTD that also incorporates adult learning principles and would be valuable and useful to teachers.
CROP WATER STRESS INDEX FOR PREDICTING YIELD LOSS IN COMMON BEAN
Authors: Quiloango-Chimarro Carlos , Coelho Rubens Duarte , Costa Jéfferson de Oliveira , Gomez-Arrieta Rafael
Published: January 2022

The crop water stress index (CWSI), an index derived from canopy temperature, has been widely studied as a physiological indicator of plant water status to optimize irrigation in common beans. However, it is not clear how this index could contribute to yield prediction as a decision support tool in irrigation management. This paper aimed to use the CWSI for predicting yield loss in common bean (Phaseolus vulgaris L.) subjected to water stress under drip irrigation. A rain shelter experiment was conducted using a completely randomized design with five replications. The indeterminate growth cultivar TAA Dama was subjected to three irrigation treatments: 100% of the field capacity (FC), 75 and 50% FC from 20 days after sowing (DAS) until the end of the crop cycle. Grain yield was reduced by 42% under 50% FC treatment. Furthermore, stomatal conductance was reduced under this treatment, whereas the CWSI and canopy temperature increased as irrigation levels decreased. The relationship between grain yield and CWSI (R2=0.76, RSME=2.35g) suggests that canopy temperature data could be used to forecast grain yield losses. In conclusion, farmers can have a low-cost, effective technique for making water management decisions in common bean.

Resumo: O objetivo deste estudo foi analisar os fatores associados aos casos de anomalias congênitas na perspectiva dos determinantes sociais da saúde no Estado do Rio Grande do Sul, Brasil. Trata-se de um estudo do tipo caso-controle, com todas as duplas de mães e nascidos vivos no período de 2012 a 2015 no estado, sendo considerado o total de nascidos vivos com anomalia congênita (5.250), e realizada amostragem aleatória de 21 mil sem anomalia congênita, conforme as informações das Declarações de Nascidos Vivos. Para análise estatística, foram realizados testes qui-quadrado e modelos de regressão logística com o SPSS. O modelo de Dahlgren & Whitehead foi utilizado como base para agrupamento e discussão das variáveis. No modelo multivariado, todas variáveis que se mostraram associadas significativamente com o desfecho foram no sentido de aumentar a chance de nascimentos com anomalia congênita: as mulheres pretas tiveram 20% mais chance, comparadas às brancas (OR = 1,20; valor de p = 0,013); ter mais de 40 anos aumentou em 97% a chance, quando comparadas às de 18 a 29 anos; as mulheres com menos de quatro anos de estudo apresentaram 50% mais chance, comparadas às mulheres com 12 anos ou mais de estudo (OR = 1,50; valor de p = 0,001); as mulheres que não realizaram nenhuma consulta de pré-natal tiveram 97% mais chance, comparadas às mulheres que realizaram sete ou mais consultas (OR = 1,97; valor de p = 0,001); e a ocorrência de abortos/perdas fetais aumentou em 17% a chance, em relação a nunca ter tido abortos/perdas fetais prévios (OR = 1,17; valor de p = 0,001). Os resultados trazem à discussão as desigualdades raciais e sociais, relacionando-as às iniquidades em saúde.

Abstract: Automatic geocoding methods have become popular in recent years, facilitating the study of the association between health outcomes and the place of living. However, rather few studies have evaluated geocoding quality, with most of them being performed in the US and Europe. This article aims to compare the quality of three automatic online geocoding tools against a reference method. A subsample of 300 handwritten addresses from hospital records was geocoded using Bing, Google Earth, and Google Maps. Match rates were higher (> 80%) for Google Maps and Google Earth compared with Bing. However, the accuracy of the addresses was better for Bing with a larger proportion (> 70%) of addresses with positional errors below 20m. Generally, performance did not vary for each method for different socioeconomic status. Overall, the methods showed an acceptable, but heterogeneous performance, which may be a warning against the use of automatic methods without assessing quality in other municipalities, particularly in Chile and Latin America.
A proposta de convenção internacional sobre a resposta às pandemias: em defesa de um tratado de direitos humanos para o campo da saúde global
Authors: Viegas Leandro Luiz , Ventura Deisy de Freitas Lima , Ventura Miriam
Published: January 2022

Em novembro de 2021, a Organização Mundial da Saúde (OMS) deu início à negociação de uma convenção, acordo ou outro instrumento internacional sobre a resposta às pandemias. Neste ensaio, defendemos e justificamos a tese de que o novo pacto deve ser um tratado de direitos humanos, como condição indispensável para a prevenção de novas pandemias e eficiência da resposta global quando elas ocorrem. Após o breve resgate da origem das negociações, apresentamos os principais conteúdos normativos que correspondem a um enfoque de direitos humanos: a instituição da regra de indissociabilidade entre medidas quarentenárias e de proteção social; e a regulamentação do acesso a tecnologias farmacêuticas. A seguir, em seção dedicada ao tema da efetividade do futuro tratado, classificamos as propostas existentes em ajustes tecnocráticos, como alterações no procedimento de declaração de emergências; mecanismos de transparência e controle, a exemplo da adoção de um mecanismo de Revisão Periódica Universal (RPU), similar ao do Conselho de Direitos Humanos das Nações Unidas, para monitorar obrigações dos Estados relacionadas à saúde; poderes coercitivos que seriam outorgados à OMS ou outra agência, tais como inspeções nos territórios nacionais realizadas por cientistas independentes; e mecanismos de coordenação política, como a criação de um Conselho Global de Ameaças à Saúde. Concluímos que há risco de adoção de um sistema mais eficiente de vigilância para alertar o mundo desenvolvido sobre ameaças oriundas de países em desenvolvimento, em lugar de um tratado capaz de contribuir para evitar que populações mais vulneráveis continuem sendo devastadas por pandemias cada vez mais frequentes.

Objetivo Examinar as consequências futuras do envelhecimento populacional e dos ganhos em longevidade, diferenciados por sexo, nos custos assistenciais das operadoras de planos de saúde. Para tanto, utilizaram-se os dados disponibilizados pela Agência Nacional de Saúde Suplementar (ANS) e pelo Instituto Brasileiro de Geografia e Estatística (IBGE). Método Utilizou-se o modelo de padronização, entre 2016 e 2045, variando apenas a estrutura etária populacional. Resultados Os resultados indicam que o processo de envelhecimento populacional é mais acentuado para a população feminina e mais intenso entre os beneficiários dos planos individuais/familiares se comparados aos dos planos coletivos. As internações e os exames complementares permanecerão os mais onerosos entre os itens assistenciais. Em relação aos impactos da longevidade, constatou-se que os maiores gastos esperados de usuários com mais de 59 anos de idade até a morte são com as internações e entre as mulheres, nos planos individuais/familiares. Conclusão O envelhecimento populacional e aumento de longevidade, principalmente para mulheres, vão impactar os custos dos planos de saúde, com maior intensidade os individuais/familiares. A saúde suplementar precisa se preparar para os desafios demográficos impostos aos custos futuros, buscando políticas capazes de minimizá-los.

Published: January 2022

Abstract Background Walking devices and other forms of assistive technology (AT) can benefit older adults by supporting mobility and social interactions, but usage outside of high-income countries is generally low. Objective To examine the factors associated with AT use and whether AT use is associated with higher levels of social participation among older adults in Brazil. Method The 2013 Brazilian National Health Survey interviewed 23,815 individuals 60 years or older. Descriptive and logistic regression analyses were used to examine AT use, including canes and walkers, to assist with walking and social participation. Results Among older adults with mobility difficulty, 34.0% (95% CI 31.2- 36.9) reported using AT. Prevalence of the use of AT for walking increases with age: 21.4% of those 60-69 years reported using AT while 58.5% of those 90 years or older did. AT was negatively associated with participation in social activities. Conclusion Our analyses focused on older adults with mobility limitations who need appropriate transportation and environment adaptations to engage socially. Contrary to studies in more developed countries, among Brazilians, AT use is negatively associated with social interactions. The resulting confinement seems to lead to social isolation.

BIOMEDICINE ON HORMONE MEDIATION OF SPORTS IN ADOLESCENT HEIGHT DEVELOPMENT
Authors: Gao Lulu , Tian Jian
Published: January 2022

ABSTRACT Introduction: Physical exercise is an important factor in regulating energy balance and body composition. Exercise itself is a kind of body stress. It involves the central nervous system, cardiovascular, respiratory, endocrine, and other systems. Sports have various effects on the hormones in adolescent height development. Objective: This article analyzes the effects of different time and load exercise training on the levels of serum testosterone, free testosterone, and cortisol in young athletes. Methods: The athletes’ blood samples were collected at the quiet time in the morning before each experiment, immediately after exercise, and at three time intervals the next morning. Then blood testosterone (T), free testosterone (FT), and corticosteroids (C) were measured. Results: One-time and one-day high-volume training can cause a decrease in serum testosterone and free testosterone levels and an increase in cortisol hormones in young athletes. The testosterone level of young athletes rises immediately after exercise. Conclusion: Hormonal changes after physical exercise provide a scientific basis for athlete exercise load prediction and exercise plan formulation.

ANALYSIS OF THE CARDIOPULMONARY ENDURANCE RESPONSE OF WOMEN TO AEROBIC EXERCISE
Authors: Tian Hua
Published: January 2022

ABSTRACT Introduction: The main purpose of aerobic exercise is to enhance cardiopulmonary endurance, so it is necessary to build cardiopulmonary endurance response models based on different frequencies of aerobic exercise. Objective: To study the cardiopulmonary endurance response of women to different frequencies of aerobic exercise. Methods: Twenty young female desk workers (female teachers and civil servants) who worked out at a fitness club were randomly divided into two groups. Cardiopulmonary function, both before and after 16 weeks of aerobic exercise at different exercise loads, was studied and analyzed. Results: After 16 weeks of aerobic exercise at different exercise loads, all the young women had significantly improved their vital capacity (VC), and their maximum oxygen uptake ability was improved to a certain extent. Compared with the 45-minute aerobic exercise group, the vital capacity (VC)of 90-minute aerobic exercise group was significantly increased (P>0.05). Conclusions: When performed at a consistent frequency level, aerobic exercise with a relatively high exercise load can better develop the body’s respiratory system function. This may be due to deep stimulation of the respiratory system from high-load aerobic exercise, and ultimately to the intensive exercising of lung function. Level of evidence II; Therapeutic studies - investigation of treatment results.

Published: January 2022

ABSTRACT Introduction: Heart rate and blood pressure are important physiological indicators that reflect cardiovascular function, and they are widely used because they are convenient and practical to measure. Objective: To study the characteristics of cardiovascular changes in athletes under different training conditions. Methods: Thirty-four male students majoring in physical education in universities (group A) and 22 male non-sports majors (group B) with no formal training history were randomly selected. Heart rate before and after exercise and heart rate recovery rate at different stages of the recovery period were compared. Results: As regards heart rate changes in the recovery phase after loading, both groups showed a continuous decline, although the drop in heart rate of group A was slightly lower than that of group B (153.03± 15.88 beats/min, dropped to 110.69± 15.78 beats/minute, 171.00± 14.67 beats/minute dropped to 122. 82± 13.77 beats/min, respectively). However, the heart rate recovery rate of group A (59.40%) was significantly higher than that of group B (49.42%) (P<0.05). Conclusions: Physical exercise plays a significant role in promoting physical fitness and its effect on improving cardiovascular function is especially evident.

Published: January 2022

ABSTRACT Introduction: Improving cardiovascular function is one of the main training goals of many sports. Objective: To understand the characteristics of the cardiovascular response of athletes under different training conditions. Methods: Thirty male basketball students were enrolled. The subjects were divided into A and B groups according to their years of training, with 15 students in each group. Exercise fatigue tests were performed, starting at a low intensity and gradually increasing the load to a relatively high degree of fatigue. Results: The RMSSD value was 42.82±31.41ms in group A and 46.48±35.26ms in group B undera low fatigue state. The LF/HF value of the athletes in group A was 2.86±1.47 and the LF/HF value of the athletes in group B was 2.94±1.68. The RMSSD value was 40.78±31.17ms and 32.37±36.42ms for groups A and B, respectively, undera high fatigue state. Conclusions: Athletes with more years of training can mobilize more cardiac reserves to meet the increase in exercise load in a fatigue state and have better autonomic nervous regulation in the process of reaching a higher degree of fatigue state. Level of evidence II; Therapeutic studies - investigation of treatment results.

Published: January 2022

ABSTRACT Introduction: The anterior cruciate ligament (ACL) is one of the important structures of knee joint stability. Objective: To investigate the application of medical training therapy (MTT) in the functional recovery of patients after anterior cruciate ligament reconstruction. Methods: Eighty patients who were treated in a secondary hospital were selected as the study subjects and were divided into a control group and an observation group according to a random number meter, with 40 cases per group. We compared Lysholm knee function scores, the range of motion (ROM), daily life capability (ADL scale), pain degree (VAS rating), knee stretch muscle score, and standing balance ability score of the two groups 3 months after intervention. Results: After intervention, the first time getting out of bed, the doctor-patient satisfaction score, and the average length of stay were better in the observation group than in the control group (P<0.05). The excellent rate of knee function in the observation group was 92.50%, which was significantly higher than 70.00% in the control group (P<0.05). Conclusions: MTT therapy can significantly improve knee the function and pain level of patients after anterior cruciate ligament reconstruction, shorten the length of hospital stay, promote rehabilitation, improve the therapeutic effect, and improve the quality of life of patients. Level of evidence II; Therapeutic studies - investigation of treatment results.

Abstract The main purpose of this study was to find out a possible association between ABO blood groups or Rh and diabetes mellitus (DM) in the local population of eight (8) different towns of Karachi, Pakistan. For this purpose a survey was carried out in Karachi to have a practical observation of these towns during the period of 9 months from June 2019 to Feb. 2020. Out of eighteen (18) towns of Karachi, samples (N= 584) were collected from only eight (8) Towns of Karachi and gave a code-number to each town. Diabetic group sample was (n1=432) & pre-diabetes sample was (n2 =152). A standard Abbot Company Glucometer for Random Blood Sugar (RBS) and Fasting Blood Sugar (FBS) tests, standard blood anti sera were used for ABO/Rh blood type. Health assessment techniques were performed ethically by taking informed consent from all registered subjects. Finally data was analyzed by SPSS version 20.0. In our current study, the comparison of ABO blood groups frequencies between diabetic and pre-diabetic individuals were carried out. The percentage values of blood Group-B as given as: (32% in DM vs. 31% in pre-diabetics), followed by blood Group-O as: (18% in DM vs. 11% in pre-diabetics). Contrary to Group-“B” & “O”, blood Group-A and Group-AB were distribution percentage higher pre-diabetic as compared to DM patients, as given as: Group-A (32% in pre-diabetics vs. 26% in DM) & Group-AB (26% in pre-diabetics vs. 24% in diabetic’s patients). In addition, percentage distribution of Rh system was also calculated, in which Rh+ve Group was high and more common in DM patients as compared to pre-diabetics; numerically given as: Rh+ve Group (80% in DM vs. 72% in pre-diabetics). Different views and dimensions of the research topic were studied through literature support, some have found no any association and some established a positive association still some were not clear in making a solid conclusion. It is concluded that DM has a positive correlation with ABO blood groups, and people with Group-B have increased susceptibility to DM disease.

Abstract Earias vittellaFabricius, 1794 (Noctuidae: Lepidoptera) is deliberated to be one of the most destructive pests of cotton and okra vegetation in the world including Asia. The pest has established resistance to various synthetic insecticides. The use of bio-pesticide is one of the unconventional approaches to develop a vigorous ecosystem without harming non- target pests and beneficial natural insect fauna. In the present study, the toxicity levels of Citrullus colocynthis seed extract have been evaluated against the populations of E. vittellaunder standardized laboratory conditions. The toxic effects of C. colocynthis on development periods, protein contents and esterase activity of the life stages of E. vittella were also evaluated. The toxicity levels of methanol, ethanol, hexane, water and profenofos were evaluated on the 1st instar larvae of E. vittella. LC30 and LC80 concentrations exhibited the effectiveness of methanol-based C. colocynthis seed extract against 1st instar larvae of E. vitella. The enhanced larval and pupal periods were revealed in treated samples during the comparison with untreated samples. The intrinsic rate of increase, net reproductive rate in the LC30 and LC80 concentrations exposed larvae remained less than the control treatment. Fecundity, the esterase activity and protein contents were declined in LC30 and LC80 treated samples as compared to the control. The present findings suggest that C. colosynthis extracts based botanical insecticides are beneficial, ecosystem sustainable and can be integrated with insect management programs from environment safety perspective.

Abstract The present study involves the chemical and bacteriological analysis of water from different sources i.e., bore, wells, bottle, and tap, from Peshawar, Mardan, Swat and Kohat districts of Khyber Pakhtunkhwa (KP) province, Pakistan. From each district, 50 water samples (10 samples from each source), regardless of urban and rural status, were collected from these sources and analysed for sulphates, nitrates, nitrites, chlorides, total soluble solids and coliforms (E. coli). Results indicated that majority of the water sources had unacceptable E. coli count i.e.> 34 CFU/100mL. E. coli positive samples were high in Mardan District, followed by Kohat, Swat and Peshawar district. Besides this, the some water sources were also chemically contaminated by different inorganic fertilizers (nitrates/nitrites of sodium, potassium) but under safe levels whereas agricultural and industrial wastes (chloride and sulphate compounds) were in unsafe range. Among all districts, the water quality was found comparatively more deteriorated in Kohat and Mardan districts than Peshawar and Swat districts. Such chemically and bacteriologically unfit water sources for drinking and can cause human health problems.

Resumo As fístulas arteriovenosas (FAVs) traumáticas envolvendo os vasos axilares e subclávios são incomuns e correspondem de 5 a 10% de todos os traumas arteriais. A anatomia complexa dessa região torna desafiador o tratamento desse segmento. Neste desafio terapêutico, descrevemos o caso de um homem de 73 anos, encaminhado por edema progressivo e úlcera no membro superior direito, com história pregressa de ferimento por arma de fogo na região infraclavicular direita há cerca de 50 anos. Foi realizada angiotomografia e identificou-se FAV axilo-axilar associada à tortuosidade e dilatação aneurismática de artéria subclávia a jusante. O paciente foi submetido à intervenção endovascular com endoprótese cônica (monoilíaca) 26 × 14 × 90 mm Braile® na artéria subclávia aneurismática, posterior à saída da artéria vertebral direita, e endoprótese monoilíaca 16 × 16 × 95 mm Excluder® com sobreposição na primeira prótese, apresentando resultado satisfatório. Portanto, descreve-se a possibilidade de utilização de endoprótese aórtica em situação incomum e de exceção, com sucesso.

Resumo Contexto A insuficiência renal crônica é um problema de saúde pública mundial. A hemodiálise é a principal terapia renal substitutiva. As fístulas arteriovenosas (FAV) são uma possível escolha, mas apresentam altas taxas de falência. Objetivos Este estudo tem como objetivo avaliar a relação entre as variáveis hemodinâmicas ao ultrassom vascular com Doppler no intraoperatório e a perviedade precoce da FAV para hemodiálise. Métodos Tratou-se de um estudo prospectivo observacional. Os pacientes consecutivos foram submetidos a FAV com ultrassonografia vascular com Doppler em intraoperatório nos dias 1, 7, 30 e 60. Eles foram divididos em grupos quanto à presença ou não de perviedade primária e secundária, e o volume de fluxo (VF) e a velocidade de pico sistólico (VPS) foram comparados. Foram realizadas curvas receiver operating characteristic (ROC), com definição de valores de VPS e VF com sensibilidade (S) e especificidade (E). Resultados Foram analisados 47 pacientes, os quais preencheram os critérios de inclusão. Os valores de VPS e VF intraoperatório foram maiores nos pacientes com perviedade primária e secundária comparados àqueles com falência. Os seguintes valores apresentaram maiores sensibilidade e especificidade para predizer perviedade primária aos 30 dias: 106 cm/s para VPS venoso, S: 75%, E: 71,4%; e 290,5 mL/min para VF arterial, S: 80,6%, E: 85,7%. Para perviedade secundária aos 30 dias, foram observados: 106 cm/s para VPS arterial, S: 72,7%, E: 100%; e 230 mL/min para VF venoso, com S: 86,4%, E: 100%. Para a perviedade primária no 60º dia, foram observados: 106 cm/s para VPS venoso, S: 74,4%, E: 62,5%; e 290,5 mL/min para VF arterial, S: 80%, E: 75%. Conclusões A velocidade de pico sistólico e o VF ao ultrassom vascular com Doppler intraoperatório são preditores de perviedade precoce na FAV para hemodiálise.

Abstract Background Arterial diseases represent a severe public health problem in the 21st century. Although men have a higher overall prevalence, reports have suggested that women may exhibit atypical manifestations, be asymptomatic, and have hormonal peculiarities, resulting in worse outcomes and severe emergencies, such as acute limb ischemia (ALI). Objectives To analyze the morbidity and mortality profile of ALI emergencies in Brazil between 2008 and 2019. Methods An ecological study was carried out with secondary data from SIH/SUS, using ICD-10 code I.74 The proportions of emergency hospital admissions and in-hospital mortality rates (HMR) by gender, ethnicity, and age were extracted from the overall figures. P<0.05 was considered significant. Results From 2008 to 2019, there were 195,567 urgent hospitalizations due to ALI in Brazil, 111,145 (56.8%) of which were of men. Women had a higher HMR (112:1,000 hospitalizations) than men (85:1,000 hospitalizations) (p<0.05), and a higher chance of death (OR=1.36; p<0.05). Furthermore, mean survival was significantly higher among men (8,483/year versus 6,254/year; p<0.05). Stratified by ethnicity, women who self-identified as white (OR=1.44; p<0.05), black (OR=1.33; p<0.05), and brown (RR=1.25; p <0.05) had greater chances of death than men in the same ethnicity categories. Moreover, women over the age of 50 years had a higher chance of death, with a progressive increment in risk as age increased. Conclusions There was a trend to worse prognosis in ALI emergencies associated with women, especially in older groups. The literature shows that the reasons for these differences are still poorly investigated and more robust studies of this relevant disease in the area of vascular surgery are encouraged.

Abstract Syphilitic aortitis is a rare complication of tertiary syphilis, which can lead to aortic aneurysm formation, aortic valvular insufficiency, and ostial coronary stenosis. Syphilis has re-emerged worldwide over recent decades and vascular surgeons should be aware of its cardiovascular manifestations. Atypical clinical presentation, such as hemoptysis and a computed tomography angiography pattern of a thicker aneurysmal wall with ulcer-like aneurysm projections, should raise suspicion of syphilitic aortic aneurysm. An early diagnosis and appropriate surgical and medical therapies significantly contribute to successful treatment and favorable prognosis. Herein is reported the case of an 82-year-old male patient, positive for syphilis infection, with impending aortic arch aneurysm rupture treated with a hybrid arch repair. After 7 months, the patient was brought to the emergency room in cardiac arrest. Unsuccessful cardiopulmonary resuscitation maneuvers were performed, and an autopsy showed cardiac tamponade due to rupture of the ascending aorta.
