OSTEOPOROSE COMO PREDITOR DE FRATURAS DO COLO FEMORAL POR QUEDAS EM IDOSOS: REVISÃO INTEGRATIVA
Authors: Medrado Katyene Dos Santos , Vieira Maísa Moura , Nogueira Suelen Marçal
Published: August 2021

Introdução: Em virtude do envelhecimento podem surgir patologias como a osteoporose que atua na redução da massa óssea, favorecendo idosos a ficarem mais suscetíveis a sofrerem quedas e possivelmente fraturas, principalmente do colo femoral. A intervenção cirúrgica precoce no pós-fratura é imprescindível, pois a demora no tempo de internação e realização das cirurgias podem aumentar as taxas de letalidade. Objetivo: Verificar se a osteoporose é um fator predisponente para fraturas do colo femoral por quedas em idosos, se o gênero pode influenciar na progressão da patologia, além das mortalidades. Metodologia: Trata-se de uma revisão integrativa da produção científica, com buscas realizadas na biblioteca virtual da saúde (BVS), com inclusão da LILACS, MEDLINE, e na Cochrane Library no período compreendido entre 2015 e 2020, sendo incluídos 8 estudos nos idiomas inglês, português e espanhol para análises. Resultados e discussão: Foram utilizados diferentes instrumentos como: densitometria óssea, Fracture Risk Assessment Tool (Frax), questionários, softwareTrabecular Bone Score (TBS), e Espectroscopia Dispersiva de raios-x (EDS) para avaliação dos indivíduos, a osteoporose foi observada na maioria dos pacientes, porém nem todos tinham conhecimento do diagnóstico, o gênero feminino prevaleceu devido a diminuição dos níveis de estrogênio. Nas fraturas, as quedas se destacaram, 66,43% necessitaram de apoio instrumental, e 11% foram à óbito dentro de um ano. Conclusão: A osteoporose pode ser considerada uma preditora de fraturas do colo femoral em idosos, principalmente em mulheres, observa-se a necessidade de mais estudos com populações específicas, que evidenciem tais episódios podendo levar a morte.

Introdução: A história natural do câncer cervical está associada a presença persistente da infecção pelo Papilomavírus humano (HPV) de alto risco. Vários fatores imunológicos, estão envolvidos nesse processo, entre eles a IL-10, uma citocina multifuncional que auxilia na progressão tumoral.Objetivo: Descrever o papel da IL-10 na infecção pelo HPV de alto risco em cânceres do colo do útero. Metodologia: Tratou-se de uma revisão integrativa da literatura, em que foram analisadas publicações indexadas na base MEDLINE, consultadas por meio do PubMed; Biblioteca Virtual de Saúde (BVS) e Scientific Eletronic Library Online (SciELO), e buscadores como Google acadêmico. Resultado e Discussão: Sete estudos foram incluídos na revisão, os quais mostraram que níveis mais altos de IL-10 estão presentes em microambientes tumorais com crescimento celular induzido pelo HPV. A prevalência geral do HPV foi de 85,7%. A principal metodologia de análise da IL-10 foi ELISA, e o tipo histológico tumoral mais encontrado foi o carcinoma de células escamosas (CEC). CONCLUSÃO: A IL-10 tem o papel de ajudar na promoção da carcinogênese induzida por HPV de alto risco em cânceres do colo do útero. Estudos que investiguem o papel da IL-10 associada ao HPV são escassos, mas necessários para traçar um caminho mais claro da atuação da IL-10 na resposta imunológica durante o processo carcinogênico.

Published: August 2021

The main goal of this research is to examine the motivation of entrepreneurs from Moscow and the Moscow region in conducting entrepreneurial activity in present economic conditions, and to identify the obstacles slowing down this activity. For implementing this goal a survey of 63 small business owners was conducted. To collect the data, authors selected the ME (micro-enterprise), the SB (small business) and the SME (small and medium-sized enterprise). The actors questioned were entrepreneurs and more particularly the heads of companies running an ME, SB or SME in Moscow and its regions. Using research methods as factor analysis and Cronbach’s Alpha, a hierarchy of the different motives and entrepreneurial barriers were constructed. Investigation results show that regarding motivations of entrepreneurs, 4 components were obtained: extrinsic motivations composed of 4 items, intrinsic motivations composed of 6 items, motivations linked to independence and autonomy with 3 items and motivations related to the safety and well-being of the family with 3 items. In terms of barriers or obstacles encountered by Russian entrepreneurs, in regards with the literature review, we obtained 5 components: barriers of legitimacy consisting of 3 items, administrative barriers with 3 items, financial barriers with 2 items, managerial barriers with 3 items and finally competitive barriers with 3 items. The novelty of this study is to improve knowledge of the motivations and barriers that entrepreneurs in Moscow and its region encounter in the course of their activity.
Learning How to Surf: Reconstructing the Propagation and Origin of Gravitational Waves with Gaussian Processes
Authors: Cañas-Herrera Guadalupe , Contigiani Omar , Vardanyan Valeri
Published: August 2021

Soon, the combination of electromagnetic and gravitational signals will open the door to a new era of gravitational-wave (GW) cosmology. It will allow us to test the propagation of tensor perturbations across cosmic time and study the distribution of their sources over large scales. In this work, we show how machine-learning techniques can be used to reconstruct new physics by leveraging the spatial correlation between GW mergers and galaxies. We explore the possibility of jointly reconstructing the modified GW propagation law and the linear bias of GW sources, as well as breaking the slight degeneracy between them by combining multiple techniques. We show predictions roughly based on a network of Einstein Telescopes combined with a high-redshift galaxy survey (z ≲ 3). Moreover, we investigate how these results can be rescaled to other instrumental configurations. In the long run, we find that obtaining accurate and precise luminosity distance measurements (extracted directly from the individual GW signals) will be the most important factor to consider when maximizing the constraining power.

LIN 358 and SMC N73 are two symbiotic binaries in the halo of the Small Magellanic Cloud, each composed of a hot white dwarf accreting from a cool giant companion. In this work, we characterize these systems using a combination of spectral energy distribution (SED)-fitting to the extant photometric data spanning a broad wavelength range (X-ray/ultraviolet to near-infrared), detailed analysis of the Apache Point Observatory Galactic Evolution Experiment (APOGEE) spectra for the giant stars, and orbit fitting to high quality radial velocities from the APOGEE database. Using the calculated Roche lobe radius for the giant component and the mass ratio for each system, it is found that LIN 358 is likely undergoing mass transfer via wind Roche lobe overflow, while the accretion mechanism for SMC N73 remains uncertain. This work presents the first orbital characterization for both of these systems (yielding periods of >270 and >980 days, respectively, for SMC N73 and LIN 358) and the first global SED fitting for SMC N73. In addition, variability was identified in APOGEE spectra of LIN 358 spanning 17 epochs over two years that may point to a time variable accretion rate as the product of an eccentric orbit.

A Sanity Check for Planets around Evolved Stars
Authors: Döllinger M. P. , Hartmann M.
Published: August 2021

We present the radius–period plot for exoplanet candidates around giant stars. The diagram contains two distinct regions. While planets of giants with radii smaller than 21 R
⊙ exhibit a wide range of orbital periods, there is evidently a lack of both relatively short-period (≤300 days) and long-period (≥800 days) planets around bigger stars. In other words, planets around K giants all have similar orbital periods above a certain stellar radius, presumably pointing out a new phenomenon which preferably occurs in stars with radii larger than ∼21 R
⊙. So far, it is speculative if we are seeing rotational modulation due to some kind of surface structure or an unprecedented form of nonradial stellar oscillations. Consequently, the radius is the second key parameter for giants apart from the stellar mass. Thus, we propose the radius–period plot as a tool to check the plausibility of planetary companions around more challenging host stars by taking into account their stellar identity (e.g., stellar radius and metallicity) to exclude intrinsic stellar variability.
Gerromorpha (Hemiptera: Heteroptera) from the Metropolitan Region of Santarém, Brazil, including three new species of Microvelia Westwood, 1834 (Veliidae: Microveliinae)
Authors: dos Santos Suzane , Rodrigues Juliana , Couceiro Sheyla , Moreira Felipe
Published: August 2021

Gerromorpha (Hemiptera: Heteroptera) comprises more than 2100 species of semiaquatic bugs, most of which have the ability to walk on the surface of the water. So far, 238 species have been recorded from Brazil, but several portions of the country remain poorly explored. The Metropolitan Region of Santarém (MRS), Pará State, Brazil, lacks faunistic and taxonomic studies concerning this group and the local fauna is under threat due to human actions.

Aiming to fill gaps concerning the diversity and distribution of Gerromorpha in the Amazon, a survey of the semi-aquatic bugs from the MRS is presented. Collections were made in 33 aquatic ecosystems in the different phytophysiognomies within this area from July 2019 to October 2020. As a result, a checklist with 44 species recorded from the three municipalities of the MRS is presented. Furthermore, three new species of the genusMicroveliaWestwood, 1834 (M. belterrensissp. nov.,M. hamadaesp. nov.andM. sousorumsp. nov.) are described, two species are recorded for the first time from Brazil (Microvelia aschnakiranaeMakhan, 2014 andRhagovelia graziaeGalindo-Malagón, Morales & Moreira, 2021), two from Pará State (Microvelia longipesUhler, 1894 andParavelia dilatataPolhemus & Polhemus, 1984) and 15 from the MRS (Brachymetra lataShaw, 1933,B. shawiHungerford & Matsuda, 1957,Tachygerris adamsoni(Drake, 1942),Microvelia pulchellaWestwood, 1834,Rhagovelia brunaeMagalhães & Moreira, 2016,R. evidisBacon, 1948,R. jubataBacon, 1948,Callivelia conata(Hungerford, 1929),Oiovelia cunucunumanaDrake & Maldonado-Capriles, 1952,Paravelia bullialataPolhemus & Polhemus, 1984,Stridulivelia alia(Drake, 1957),S. stridulata(Hungerford, 1929),S. strigosa(Hungerford, 1929),S. tersa(Drake & Harris, 1941) andS. transversa(Hungerford, 1929)).

Published: August 2021

Many institutions harbor living collections in the form of living plants, animals, microrganisms or seeds. In the framework of the TDWG collections and specimen descriptions standards, it has become important to align exisiting standards for living collections and specimens or to identify where concepts or controlled vocabularies would be needed in the current TDWG standards. In September 2021 a workshop was organized in the framework of the COST Action Mobilise (https://www.mobilise-action.eu/) to get a better common understanding of the different types of living collections to consider and set the scene for further work on standards alignments. The EU COST Action CA17106 on “Mobilising Data, Experts and Policies in Scientific Collections”.

Invited experts to these workshop were representatives of the TDWG Collection Description Group, the GGBN and TDWG molecular collections group, living plants collections and seed banks (Botanic Gardens Conservation International: BGCI, https://www.bgci.org/), living animal and biobanks (European Association of Zoos and Aquaria: EAZA, https://www.eaza.net/) and the culture collections (World Federation for Culture Collections: WFCC, http://www.wfcc.info/), who gave presentations on their currently used standards and challenges.

The second day was devoted to break out sessions to brainstorm the specific needs for the different living collections with the aim to check and update the controlled vocabularies and concepts as needed.

Identified topics were :

Session 1: Voucher specimens of living accessions.

Session 2: Living collections and GBIF.

Session 3: How do we compare botanical gardens with herbaria?

Session 4: How do we compare zoos and aquaria with natural history collections?

Session 5: Culture collections: best practices and guidelines.

Sternal reconstruction and omentoplasty after mediastinitis
Authors: Stoev Hristo
Published: August 2021

Deep sternal infections are serious complications after open heart surgery. We present a case of a 59-year-old female with uncontrolled diabetes who underwent aortocoronary bypass surgery in another cardiac surgery department. After the surgical intervention sternal dehiscence and wound infection occurred, which was followed by two unsuccessful attempts for sternal refixation. Two months after the initial procedure the patient was admitted to our institution with severe dyspnea and paradoxical movement of the thorax. Computed tomography revealed a huge defect of the sternum and metal osteosynthesis with a titanium plate and omentoplasty was performed. The patient was followed-up for one year with excellent postoperative result.
Concurrent treatment of HIV, disseminated Mycobacterium avium complex and HCV-infection

Published: August 2021

Patients with HIV-infection diagnosed at late stages usually have significant immunosuppression and demand simultaneous antiretroviral therapy and treatment of opportunistic infections. The presence of HCV coinfection makes treatment even more challenging because of possible adverse effects and drug-drug interactions. HCV cure in such clinical situations not only prevents fibrosis progression, but can also enhance virologic and/or immunologic response to antiretrovirals and thus effective treatment of opportunistic infections. Thorough consideration of all existing diseases and drug interactions of the combined therapy makes simultaneous treatment of HIV, chronic hepatitis C, and opportunistic infections not only possible but the best way to improve outcomes in a complex clinical situation.
Massive subgaleal hematoma in a 62-year-old man treated with apixaban as a consequence of mild head trauma

Published: August 2021

Subgaleal hematoma, accumulation of blood in the loose areolar tissue of the subgaleal space of the skull, is considered the most catastrophic complication of instrumental delivery. It is a rare finding in older ages, usually associated with coagulation disorders, severe head trauma leading to skull base fractures and accidental or abusive hair pulling. Complications include periorbital necrotising fasciitis, permanent blindness, infections and, in extreme rare cases, airway obstruction. Most cases of subgaleal hematoma resolve spontaneously, without the need of aspiration or drainage.

We present here the case of a 62-year-old male on anticoagulant therapy with apixaban for chronic atrial fibrillation, who came to the emergency department after a car accident suffering from mild head trauma. The patient was complaining of a diffuse headache and physical examination showed a large ecchymosis and edema on the frontal area of the head. His neurological examination was unremarkable. Full-body computed tomography (CT) revealed a fracture of the third right rib. Twelve hours after admission, due to an excessive decrease of hematocrit, a second CT was performed. Although the images didn’t show intracranial hemorrhage or skull base fractures, a large and diffuse hematoma of the subaponeurotic space was observed and the diagnosis of subgaleal hematoma was confirmed.

Massive subgaleal hematoma after mild head trauma is rather infrequent. Early diagnosis improves outcomes and can avert serious complications. Therapeutic strategy should be based on the severity of each case. In our case, conservative treatment appeared to be a valid alternative to surgery, as hematoma resolved spontaneously within 10 days. It is noteworthy that the use of anticoagulation is the only evident factor that could have been the precipitating factor for the development of the hematoma in our patient.
Primary renal echinococcosis – a rare location of hydatid disease
Authors: Mladenov Boris , Dorosiev Emil
Published: August 2021

Hydatid disease is a condition affecting mainly the liver or, to a lesser extent, the lungs. We present an uncommon case of a primary renal echinococcosis in a young man complaining of intermittent hematuria, dull flank pain, and palpable mass in the left lumbar and lateral abdominal area which increases its size over time. After initial self-treatment with painkillers and antibiotics, the patient was referred to a urological clinic, where the physical examination revealed a large tumour mass in the left kidney. Ultrasound showed a large multilocular renal cyst, with a CT highly suspicious for renal echinococcosis (15×12.8×24.2 cm). Serological tests confirmed presence of IgG against Echinococcus. The patient was operated using the lumbar approach and nephrectomy was performed. The man recovered completely after surgery without the need for further treatment.

Published: August 2021

Armoured crickets are an important food source in some parts of Zimbabwe. These insects are abundant in some regions but however, they are under utilised and not much is known about their nutritional value. The aim of this study was to determine the nutritional profile of the armoured cricket (Acanthoplus discoidalis). Armoured crickets were collected from a structured sampling framework in Mbire district Mashonaland Central province of Zimbabwe. Removal of the head and thorax, degutting and boiling were done. A proximate analysis was carried out followed by mineral, amino acid and fatty acid profiling of the prepared insects. Analyses were done on a dry basis.A. discoidalis contained 69.2% protein, 16.8% fat, 8.6% ash, 1.2% carbohydrate, 4.2% chitin and 454.3 Kcal/100 g energy. A 100 g dry weight quantity of insect contains 11.48 mg iron which is enough to meet the required daily intake of 10.0-20 mg/day for an adult. The zinc (4.37 mg/100 g dry weight) and phosphorus (491.4 mg/100 g dry weight) content inA. discoidalis almost meets the reference nutrient intake for adults. Essential amino acids, leucine (60.7 mg/g protein) had the highest concentration followed by phenylalanine+tyrosine (59.3 mg/g protein), valine (48.4 mg/g protein), lysine (46.7 mg/g protein), threonine (37.4 mg/g protein), isoleucine (26.4 mg/g protein), methionine+cysteine (20.9 mg/g protein) and histidine (16.5 mg/g protein) the least concentration. In total, 9 saturated fatty acids were determined of which stearic acid and palmitic acid had the highest concentrations of 2,034.5 mg/100 g and 2,005.3 mg/100 g respectively. Four mono unsaturated fatty acids were determined of which oleic acid and palmitoleic acid had the highest concentrations of 361.4 mg/100 g and 305.2 mg/100 g respectively. Four poly-unsaturated fatty acids were determined of which eicosapentaenoic and α-linolenic acid had the highest concentrations of 1,598.0 mg/100 g and 185.6 mg/100 g respectively.A. discoidalis is good source of protein, the minerals iron, zinc and phosphorus, some essential amino acids and poly-unsaturated fatty acids.

Published: August 2021

We study the combinatorial Reeb flow on the boundary of a four-dimensional convex polytope. We establish a correspondence between "combinatorial Reeb orbits" for a polytope, and ordinary Reeb orbits for a smoothing of the polytope, respecting action and Conley-Zehnder index. One can then use a computer to find all combinatorial Reeb orbits up to a given action and Conley-Zehnder index. We present some results of experiments testing Viterbo's conjecture and related conjectures. In particular, we have found some new examples of polytopes with systolic ratio \begin{document}$ 1 $\end{document}.

Let $ G $ be a graph. For a set $ \mathcal{H} $ of connected graphs, an $ \mathcal{H} $-factor of a graph $ G $ is a spanning subgraph $ H $ of $ G $ such that every component of $ H $ is isomorphic to a member of $ \mathcal{H} $. A graph $ G $ is called an $ (\mathcal{H}, m) $-factor deleted graph if for every $ E'\subseteq E(G) $ with $ |E'| = m $, $ G-E' $ admits an $ \mathcal{H} $-factor. A graph $ G $ is called an $ (\mathcal{H}, n) $-factor critical graph if for every $ N\subseteq V(G) $ with $ |N| = n $, $ G-N $ admits an $ \mathcal{H} $-factor. Let $ m $, $ n $ and $ k $ be three nonnegative integers with $ k\geq2 $, and write $ \mathcal{F} = \{P_2, C_3, P_5, \mathcal{T}(3)\} $ and $ \mathcal{H} = \{K_{1, 1}, K_{1, 2}, \cdots, K_{1, k}, \mathcal{T}(2k+1)\} $, where $ \mathcal{T}(3) $ and $ \mathcal{T}(2k+1) $ are two special families of trees. In this article, we verify that (i) a $ (2m+1) $-connected graph $ G $ is an $ (\mathcal{F}, m) $-factor deleted graph if its binding number $ bind(G)\geq\frac{4m+2}{2m+3} $; (ii) an $ (n+2) $-connected graph $ G $ is an $ (\mathcal{F}, n) $-factor critical graph if its binding number $ bind(G)\geq\frac{2+n}{3} $; (iii) a $ (2m+1) $-connected graph $ G $ is an $ (\mathcal{H}, m) $-factor deleted graph if its binding number $ bind(G)\geq\frac{2}{2k-1} $; (iv) an $ (n+2) $-connected graph $ G $ is an $ (\mathcal{H}, n) $-factor critical graph if its binding number $ bind(G)\geq\frac{2+n}{2k+1} $.
A model for predicting drug-disease associations based on dense convolutional attention network
Authors: Wang Huiqing ,   College of Information and Computer, Taiyuan University of Technology, Taiyuan 030024, China, Zhao Sen , Zhao Jing , Feng Zhipeng
Published: August 2021

The development of new drugs is a time-consuming and labor-intensive process. Therefore, researchers use computational methods to explore other therapeutic effects of existing drugs, and drug-disease association prediction is an important branch of it. The existing drug-disease association prediction method ignored the prior knowledge contained in the drug-disease association data, which provided a strong basis for the research. Moreover, the previous methods only paid attention to the high-level features in the network when extracting features, and directly fused or connected them in series, resulting in the loss of information. Therefore, we propose a novel deep learning model for drug-disease association prediction, called DCNN. The model introduces the Gaussian interaction profile kernel similarity for drugs and diseases, and combines them with the structural similarity of drugs and the semantic similarity of diseases to construct the feature space jointly. Then dense convolutional neural network (DenseCNN) is used to capture the feature information of drugs and diseases, and introduces a convolutional block attention module (CBAM) to weight features from the channel and space levels to achieve adaptive optimization of features. The ten-fold cross-validation results of the model DCNN and the experimental results of the case study show that it is superior to the existing drug-disease association predictors and effectively predicts the drug-disease associations.
The Antecedents of Consumer Engagement in CSR Communication in Social Media
Authors: Alraja Mansour , Hamdoun Mohamed
Published: August 2021

This study aims to explore the ways in which targeted consumers engage with corporate social responsibility (CSR) activities on social media platforms, specifically when discussing their opinions and experiences regarding the CSR activities of their favorite brands. Therefore, the variable moral norms were integrated in the theory of reasoned action. The study data about consumers' engagement (CE) in corporate social responsibility communication (CSRC) over social media (SM) platforms—electronic word of mouth, or e-WoM—was collected from 290 actual engaged consumers in online ordering and involved in social media groups. The findings confirmed that the antecedent factors (consumers' attitudes, subjective norms, and moral norms) have a positive influence on consumers' intention to use e-WoM, while no effect was found on CE in CSRC in SM. Furthermore, e-WoM was found to have direct significant impact on CE in CSRC in SM as it mediates the relationship between the antecedent factors and CE in CSRC in SM.

Published: August 2021

This study evaluated the effects of mineral fertilizer rates on biochemical properties, cooking quality traits and root yield of sweetpotatoes. The experimental design was 4 x 4 factorial in randomized complete block with three replications. The treatment factors were four varieties of sweetpotato (Ligri, Bohye, Dadanyuie and Apomuden) and four fertilizer amendments (T1: 30-30-30 kg /ha NPK, T2: 30-30-60 kg NPK+50 kg Muriate of Potash, T3: 30-30-90 kg/ha NPK+ 100 kg Muriate of Potash and T4: Control (No fertilizer). Results showed that the fertilizer rates did not influence root yield but variety had significant difference (P<0.05). Apomuden recorded the highest average root yield of 14.5 t/ha which was significantly higher than Ligri 5.1 t/ha. Ligri recorded the highest dry matter and sugar contents of 34.63% and 67.98% respectively while Apomuden recorded the lowest dry matter content and starch content of 23.75% and 50.00% respectively. However, it recorded appreciable amount of beta-carotene and sugar contents of 32.38 mg/100g and 28.04% respectively. There were significant variety × location interactions effect (P < 0.05) on average root yield and biomass yield. The significant varietal response observed in this study implies that choice of variety is an important factor to consider in sweetpotato production.

Authors: Nsor M.E. , Akpan A.E.
Published: August 2021

The soils on diverse landforms in Ikot Esidem, Southern Nigeria were characterized and their suitability evaluated for three varieties of cocoyam. The study area was stratified into flood plains, inland valleys, gentle slopes and crest. The results indicate that sand (30-78%) dominated pedons of gentle slopes and crest while silt (25-55%) and clay (19-51%) dominated the pedons of flood plains and inland valleys. The soils of flood plains and inland valleys were moderately acid (pH 5.0-5.7), medium to high in organic carbon (6.3-20.5 g/kg) and medium to high in base saturation (BS) (46-90%). The gentle slopes and crest units were strongly acid (pH 4.0-5.1), low in organic carbon (4.0-11.3 g/kg) and base saturation (20.5-34.7%). The land suitability evaluated the flood plains and inland valleys as moderately suitable and the gentle slopes and crest as not suitable for Dasheen Type Taro. The flood plains and inland valleys were also evaluated moderately suitable, whereas gentle slopes and crest were marginally suitable for Eddoe Type Taro. Efficient water control drainage and erosion control will enhance cocoyam cultivation depending on terrain type.

The apprehension among oil palm farmers on the toxicity of glyphosate necessitated the need for an alternative herbicide for weed control in oil palm. Thus, a study was conducted at the Ni­gerian Institute for Oil Palm Research (NIFOR) to determine the efficacy of tank mixture of glu­fosinate ammonium (Basta) + indaziflam (Alion) for weed control in oil palm. The treatments consisted of glyphosate at 1.5 kg a.i ha-1, glyphosate + diuron at 1.5+2.0 kg a.i. ha-1, glufosinate ammonium at 0.4 kg a.i. ha-1, glufosinate ammonium at 0.5 kg a.i. ha-1, tank mixture of glufos­inate ammonium + indaziflam at 0.4 + 0.04 kg a.i. ha-1, tank mixture of glufosinate ammonium + indaziflam at 0.5 + 0.04 kg a.i. ha-1and weedy control. The results showed that tank mixture of glyphosate + diuron at 1.5 + 2 kg a.i ha-1, glufosinate ammonium + indaziflam at 0.4 + 0.04 kg a.i. ha-1 and glufosinate ammonium + indaziflam at 0.5 + 0.04 had the best weed control efficiency of 78.5%, 78.6% and 78.3% respectively up to 20 weeks. The study concluded that tank mixtures of glufosinate ammonium + indaziflam were as good as glyphosate + diuron for weed control in oil palm.

Pierre Bourdieu y las encuestas en sociología de la educación [Pierre Bourdieu and Surveys in Sociology of Education]
Authors: De Saint-Martin Monique , Sandoval-Aragón Sergio Lorenzo
Published: August 2021

El artículo tiene como propósito ayudar a imaginar y comprender el espíritu con el que Pierre Bourdieu y el grupo de investigadoras e investigadores que animaba concibieron, a principios de la década de 1960, sus primeras investigaciones y encuestas sobre los estudiantes y el sistema educativo. Evoca las investigaciones y encuestas dirigidas por Pierre Bourdieu que nutrieron y originaron muchos otros trabajos, como los de opinión política, sobre profesores universitarios o sobre el campo del poder. Se centra particularmente en las investigaciones y encuestas de la década de 1960, destaca el impulso que mayo de 1968 aportó a las investigaciones en educación, para luego abundar en la investigación emprendida en 1969 sobre los factores de cambio y las fuerzas de inercia en el sistema escolar. Explica que fue imperativo centrarse no sólo en el peso de la reproducción en el sistema educativo, sino también en las transformaciones que se estaban produciendo en la universidad, en el sistema educativo en general e, incluso, en toda la sociedad. En su conjunto, el artículo es un invaluable testimonio, sólidamente documentado, que permite comprender el papel central de la sociología de la educación y la cultura en el trabajo sociológico de Pierre Bourdieu.

This research deals with jurisprudential applications and issues that fall under the section of urgency in view of what is legitimate and what is prohibited. Hence, this study came to clarify the principle that Islamic jurisprudence leads to regarding urgency and the ruling on the performance of duties, which is not without aspects that revolve between haste in compliance or laxity in the performance. Therefore, the research was concerned with studying the jurisprudential issues related to the legitimate urgency in the jurisprudence of worship, including issues in the chapters of prayer, fasting, zakat and pilgrimage, as well as issues related to the urgency prohibited in these chapters. The researcher followed the comparative analytical method by following the opinions, sayings, and inferences of the jurists, discussing, criticizing and evaluating them, and what the researcher reached was that Islam looked at urgency in a fair way, and praised it in places and praised it in other places based on what is governed by the legal texts of the Qur’an and Sunnah, impact, reasonable, analogy and approval, as well. The warning of the Prophet, peace and blessings be upon him, about haste and that it is from Satan, it is clear that it is not general.

Authors: Lamberg Eric , McKenna Raymond
Published: August 2021

Childhood overweight and obesity is a serious national health problem that can lead to overweight and obesity in adulthood. Many programs have been developed to “treat” children already classified as overweight or obese. However, they represent reactionary strategies to a preventable problem. This paper describes the development of a school-based program to promote physical activity and healthy lifestyle to all students regardless of weight. Results from the initial pilot are presented, and barriers and methods to overcome these barriers are discussed. Methods: Move your Feet! is an elementary-school-based after-school club that promotes physical activity and healthy lifestyle. Attendance was recorded, BMI determined, and responses obtained on pre- and post-club questionnaires. Results: Overall child attendance rate was 91%. The average number of days/week children and parents participated in physical activity significantly increased. Over 80% of parents were “satisfied” with the way the club affected their child, themselves, and their family. Over 95% of the children enjoyed the club. There was no change in BMI. Conclusion: After-school wellness programs show promise for promoting physical activity and healthy lifestyle changes, and as a result, may have the potential to help decrease overweight and obesity in children.
Case Study - Deep Cutaneous Mass Excision Reveals an Unusual Finding
Authors: Weaver Tony , McDonald Chad , Rosenthal Andrew
Published: August 2021

Case presentation of a 62-year-old male who presented to the emergency department complaining of a mass in his right hand which began 14 days prior to evaluation. The mass was located in the proximity of the multiple neurovascular structures; therefore, surgical excision in the operating room was required. The patient’s pathological findings revealed a thick-walled, smooth surfaced cyst consistent with a bot fly larva (Dermatobia hominis) enclosed in an exoskeleton casing, rendering the diagnosis furuncular myiasis. Because areas of cutaneous myiasis are frequently misdiagnosed as pyogenic infection, it is important that the clinician maintains bot fly larvae in their differential diagnosis for a boil-type lesion in a patient that has visited the American tropics. It is imperative that providers consider surgical consultation in cases of suspected cutaneous myiasis due to the likelihood of complex anatomical structural involvement or unforeseen difficulty in removal when the larva is located subdermally with fascial encasement.

Most infective organisms have developed resistance against antibiotics. There is need to find other means to deliver antibiotics locally. There appears to be limited studies on the use of gentamicin sulphate iontophoresis in wound management. The participant in this study was a subject diagnosed with mild head injury secondary to motor vehicle accident who later developed a unilateral pressure sore on the left gluteal region. The subject received 15-minutes of gentamicin sulphate iontophoresis (Interrupted Direct Current) three times a week for five weeks. The case report showed that there was a 65.7% reduction in wound surface area of the decubitus ulcer at the end of five weeks. Also, bacterial growth reduced from very heavy growth to scanty growth at the end of the 5th week. This report suggested that gentamicin sulphate ointment iontophoresis as adjunct with traditional saline-wet-to-moist (WM) wound dressing had an effect in healing the decubitus ulcer of the participant used in this study.

Authors: Kumar Vibha
Published: August 2021

Information is critical in making health-related decisions. New communication technologies show great promise in providing ways to develop and deliver changes in health behaviors. The behavioral and communication changes in consumers, patients, providers, and organizations are being noticed at individual, community, and organizational levels due to innovations in electronic health information systems, such as personal health records (PHRs), electronic medical records (EMRs), and electronic health records (EHRs). The noted behavioral/communication changes include improved quality patient care; easy, accurate, and quick information retrieval; rapid information sharing; quick decision making; reduced medical errors due to electronic alerts; increased storage of data and records electronically; and improved information screening and reporting. Literature was reviewed using Pub Med and an internet search. RogerIn recent years, new developments have resulted in the rapid growth of communication technologies such as computer software, the Internet, email, mobile telephones, information systems, and handheld computers. Previously, computer use was predominantly available in high-level government agencies, research laboratories, and large companies. Today, computers and advanced technologies in connection with health data are the new way to manage diseases. Hospitals, healthcare organizations, health departments, and small healthcare facilities, are adopting health information systems and average citizens are using computers to access health-related information. User interfaces have improved and are being interactive with other information systems. The rate of adoption continues to increase as technology becomes cheaper and more accessible. This article discusses the effect of innovation in health information technology on the public

o objetivo foi relatar um caso de megaesôfago idiopático que foi tratado por cardiomiotomia videolaparoscópica a Heller-Pinotti em um paciente masculino, de 29 anos. Foi realizada triagem inicial com anamnese e exame físico e o paciente alegou disfagia progressiva sem alterações dos hábitos intestinais associadas; exame físico abdominal sem alterações. A investigação diagnóstica laboratorial incluiu tireoideopatia, doença de Chagas e doença do refluxo gastroesofágico. Após extensa investigação foi detectada acalasia (confirmada por esofagomanometria) idiopática, sendo assim realizada a cardiomiotomia videolaparoscópica a Heller-Pinotti. Posteriormente ao tratamento cirúrgico, o paciente apresentou boa evolução pós-operatória, não havendo queixas de pirose ou regurgitação e desaparecendo a queixa de disfagia. Declara-se boa experiência com o tratamento cirúrgico proposto, no entanto, novos estudos se tornam necessários para aprimoramento da técnica cirúrgica e consequente maior benefício para o paciente com acalasia idiopática.

 

the goal was to report a case of idiopathic achalasia that was treated by Heller-Pinotti’s videolaparoscopic cardiomyotomy in a male patient of 29 years. The initial assessment was done with clinical history and physical examination and the patient claimed progressive dysphagia without changes in bowel habits associated; abdominal physical examination without abnormalities. Laboratory diagnostic investigation included thyroidopathy, Chagas’ disease and gastroesophageal reflux disease. After extensive research, it was detected idiopathic achalasia (confirmed by esophageal manometry) and Heller- Pinotti’s videolaparoscopic cardiomyotomy was realized. After surgery, the patient presented good postoperative evolution, with no complaints of heartburn or regurgitation and the dysphagia complaint had gone. We can declare good experience with the proposed surgical treatment, however, further studies are needed to make improvements in surgical technique and consequent greater benefit to the patient with idiopathic achalasia.
The Power of Collaboration: How U.S. Cities and Corporations Can Work Together to Advance Renewable Energy
Authors: Shaver Lacey , Elwood Holly , Bonugli Celina
Published: August 2021

Large energy users with renewable energy targets—like cities and corporations—face technical, policy, and market barriers when procuring renewables for their own operations and when attempting to expand access to renewables for other energy users. Municipal-corporate collaborations can remove these barriers and advance renewable electricity generation and use across the United States. Amplifying, enhancing, and scaling these efforts can help accelerate the clean energy transition. To date, municipal and corporate renewable energy buyers have partnered on education and outreach efforts, joint procurement of renewable electricity, collaborative engagement to remove market barriers, and equitable deployment of renewables within communities. These collaborations demonstrate civic and climate leadership and yield a variety of benefits, including increased economies of scale, reduced costs and material risk, positive publicity, equitable communitywide access to renewables, and more rapid progress toward meeting individual and shared climate and energy targets. Collaborations between municipal and corporate renewable energy buyers can add complexity to project implementation but can also be substantially more impactful than one entity working alone, for example, by increasing the size of or participation in a deal. For success, they require initial outreach and discussions; alignment on goals, roles, and responsibilities; adequate funding and staffing; and continued participation from all parties.
