Perfil ginecológico e obstétrico, perda de urina e qualidade de vida de idosas com incontinência urinária
Authors: Borba de Souza Marina , Poersch Karla
Published: September 2022

A prevalência de incontinência urinária (IU) em mulheres pós-menopausa pode atingir de 30% a 70%, representando um problema mundial de saúde pública. O objetivo deste trabalho foi descrever o perfil ginecológico e obstétrico de idosas com IU, quantificar a perda de urina e avaliar o impacto na qualidade de vida. Trata-se de um estudo quantitativo, de delineamento transversal realizado com idosas vinculadas a grupos de convivência em Santo Antônio da Patrulha/RS. A coleta de dados deu-se através do International Consultation on Incontinence Questionnaire - Short Form (ICIQ-SF); de uma entrevista inicial; do King’s Health Questionnaire (KHQ) e do Pad Test de 1 hora. Participaram 25 idosas, com idade média de 70,4 ± 4,4 anos, 60% tiveram parto vaginal e 32% apresentaram prolapso de órgãos pélvicos. Houve predomínio de IU mista (64%), com média de 4,5 ± 8,2 g de urina perdida no Pad Test, e os domínios do KHQ mais afetados foram de impacto da IU (49,6 ± 24) e medidas de gravidade (42,3 ± 22,4). Houve correlação entre o Pad Test e os domínios de percepção geral de saúde (r= 0,51; p= 0,041), sono e disposição (r= 0,59; p= 0,016) do KHQ e frequência (r= -0,48; p= 0,047) do ICIQ-SF. As idosas apresentaram IU leve, e as associações sugerem que quanto maior é a perda urinária, pior é a qualidade do sono e a percepção geral de saúde e menor a frequência das perdas.

Published: September 2022

Introdução: No período gestacional, o ganho de peso e a ingestão de nutrientes devem ser suficientes para suprir as necessidades maternas e fetais. Objetivo: Analisar quali-quantitativamente o consumo alimentar de gestantes segundo o estado nutricional antropométrico.Metodologia: Estudo transversal aninhado a uma coorte com 185 gestantes. Os dados de consumo alimentar foram coletados no 1º e 3º trimestre gestacional e analisados segundo a pirâmide alimentar para gestantes eutróficas. Utilizou-se Teste T de Student para a comparação das médias de consumo de energia e nutrientes, segundo estado antropométrico. Resultados: Identificou-se insuficiência no consumo de porções e na frequência de grupos alimentares ao longo da gestação. A média de porcionamento dos grupos de cereais, tubérculos e raízes, leite e derivados mostraram-se inferiores ao recomendado pela pirâmide alimentar para gestantes. A análise quantitativa de consumo de energia e nutrientes mostrou que no primeiro trimestre gestacional mulheres sem excesso de peso tiveram consumo médio mais elevado de vitamina E (p = 0,05), vitamina A (p= 0,01) e cobre (p= 0,04). Discussão: Especula-se que esse perfil de consumo das gestantes pode ter influenciado a alteração do estado antropométrico gestacional neste estudo, uma vez que o percentual de gestantes eutróficas reduziu e o percentual de gestantes com excesso de peso aumentou ao longo da gestação. Conclusão: Identificou-se inadequação no consumo alimentar de micronutrientes no período gestacional, indicando a necessidade de avaliar a composição da dieta durante o pré-natal, uma vez que o estado nutricional materno reflete a qualidade de atenção nutricional dispensada à mulher e está associado a desfechos gestacionais positivos.

Individualised homoeopathic treatment for a longstanding meibomian cyst: A case report
Authors: Hait Himangsu , Afroza Tamara
Published: September 2022

A chalazion is a chronic sterile lipogranuloma. They are typically slowly enlarging and non-tender. A deep chalazion is caused by inflammation of a tarsal meibomian gland, while a superficial chalazion is caused by inflammation of a Zeis gland. A 4-year-old child was brought for homoeopathic treatment of a meibomian cyst of the left upper eyelid with the hope to avoid surgical intervention. After full case taking, case analysis and proper individualisation, a single homoeopathic medicine was prescribed. After 2 months of treatment, the child was relieved of her presenting symptoms and showed general improvement in health. This article provides a clinically useful review of a case with evidence about how an individualised homoeopathic medicine treated a likely surgical case successfully.

Authors: Biswas Bikash , Roy Poulamy Singha , Hazra Anupam
Published: September 2022

Alopecia areata (AA) is an autoimmune disease characterised by hair loss in patched from one or more areas of the skin. While it can affect the scalp, it may occur in other parts of the body as well. No age group is predominantly affected. This case series evaluates the effects of homoeopathic treatment in patients with AA. A total of three cases were included in this study. AA was diagnosed based on clinical symptoms. The patients were prescribed Lycopodium clavatum, Carcinosinum and Tuberculinum based on clinical signs, totality of symptoms, individualisation and miasmatic analysis. Dietary changes were recommended as well. Improvement was assessed based on symptom reduction and growth of new hair. All three patients improved clinically and new hair growth was seen. This case series provides evidence that individualised homoeopathic treatment is clinically effective in AA.

Published: September 2022

Nanostructured cerium oxide (CeO2) usually identified by way of Nano ceria is an erratic earth metal oxide which plays a technologically significant role owing to its adaptable solicitations by way of automobile finish substances, oxide ion conductors in solid oxide cells, ultraviolet absorbents and glass-polishing materials. Metal oxides are excellent innovative adsorbents aimed at the elimination of dye ingredients. In this study, we describe a nanostructured cerium oxide nanocomposite adsorbent, which displays remarkable efficiency toward the removal of widely used Congo red (CR) from aqueous systems. The CeO2 nanoparticles and CeO2 nanocomposite were prepared by using a simple co-precipitation method. Amongst the numerous approaches, adsorption is a discerning expertise for dye elimination. The cerium oxide nanoparticles solution was presented as a strong activity against E. Coli, a weak activity against Pseudomonas. The cerium oxide nanocomposites (NC) solution was presented as a strong activity against Enterobacter, a weak activity against Staphylococcus. The nanocomposites coating was successfully prepared by the effective dispersing of nanoparticles in cerium and were characterized by X-ray diffraction, Scanning electron microscopy, UV - visible spectroscopy and Fluorescence spectroscopy.

Published: September 2022

The kinetic data obtained in ruthenium(VI) catalysed oxidation of methyldiethylene glycol (MDG) in alkaline medium using potassium bromate as oxidant and transition metal ruthenium tetroxide as a homogenous catalyst. In this kinetic reaction, Hg(OAc)2 acts as a liberated bromide ion scavenger. The result shows first order with respect to KBrO3, methyldiethylene glycol (MDG) and transition metal respectively. It shows zero order dependences of the reaction on aqueous sodium hydroxide, which is used as medium of the reaction and also zero effect of mercuric acetate. In this catalysed reaction, ionic strength has positive effect. The corresponding acid was found to be main oxidation product. A plausible reaction mechanism in agreement with kinetic results was put forward.

The mechanochemical synthesis of 1-(4-Nitro phenylamino)-4,4,6-trimethyl-3,4-dihydro pyrimidine-2-(1H)- thione (Hnppt) based ligand and its metal complexes with Cu(II), Co(II), Ni(II), Mn(II), Cd(II), Pd(II) has been achieved. The synthesized ligand and its coordination complexes were evaluated for antibacterial ability and DNA photocleavage potential by using plasmid DNA. Ligand(Hnppt) was prepared and then it was allowed to chelate with different transition metals in 1:2 metal ligand ratio. All the complexes were then characterized by IR, Mass, NMR, magnetic moment, electronic spectra like spectroscopic techniques. 1H NMR data of complexes reveals that coordination occurs via nitrogen atom with the loss of a proton and IR data confirms that the thione sulphur of ligand participates in coordination with metal. Electronic spectral data revealed the octahedral and square planar geometry of coordination complexes. The formation of 2:1 ligand to metal stoichiometry was confirmed by mass spectra. It was observed that metal complexes possess good level of antibacterial and DNA cleaving potential than the ligand.
Water oxidation by a dye-catalyst diad in natural sunlight: timing and coordination of excitations and reactions across timescales of picoseconds to hours
Authors: Massad Ramzi , Cheshire Thomas , Fan Chenqi , Houle Frances
Published: September 2022

The mechanisms of how dyes and catalysts for solar-driven transformations such as water oxidation to form O2 work have been intensively investigated, however little is known about how their independent photophysical and chemical processes work together. The level of coordination between the dye and the catalyst in time determines the overall water oxidation system’s efficiency. In this computational stochastic kinetics study, we have examined coordination and timing for a Ru-based dye-catalyst diad, [P2Ru(4-mebpy-4′-bimpy)Ru(tpy)(OH2)]4+, where P2 is 4,4′-bisphosphonato-2,2′-bipyridine, 4-mebpy-4′-bimpy is 4-(methylbipyridin-4′-yl)-N-benzimid-N′-pyridine, a bridging ligand, and tpy is 2,2′:6′,2′′-terpyridine), taking advantage of the extensive data available for both dye and catalyst, and direct studies of the diads bound to a semiconductor surface. The simulation results for both ensembles of diads and single diads show that progress through the generally accepted water oxidation catalytic cycle is not controlled by the relatively low flux of solar irradiation or by charge or excitation losses, rather is gated by buildup of intermediates whose chemical reactions are not accelerated by photoexcitations. The stochastics of these thermal reactions govern the level of coordination between the dye and the catalyst. This suggests that catalytic efficiency can be improved in these multiphoton catalytic cycles by providing a means for photostimulation of all intermediates so that the catalytic rate is governed by charge injection under solar illumination alone.

3-Ketosteroid Δ1-dehydrogenases (KstD) are important microbial flavin enzymes that initiate the metabolism of steroid ring A and are useful find application in the synthesis of steroid drugs. We present a structure of the KstD from Sterolibacterium denitrificans (AcmB), which contains a previously uncharacterized membrane-associated domain and extended proton-relay system. The experimental and theoretical studies show that the steroid 1,2-dehydrogenation proceeds according to the Ping-Pong bi-bi kinetics and a two-step base-assisted elimination (E2cB) mechanism. The mechanism is validated by evaluating the experimental and theoretical kinetic isotope effect for deuterium substituted substrates. The role of the active site residues is quantitatively assessed by point mutations, experimental activity assays, and QM/MM MD modeling of the reductive half-reaction (RHR). The pre-steady-state kinetics also reveals that the low pH (6.5) optimum of AcmB is dictated by the oxidative half-reaction (OHR), while the RHR exhibits a slight optimum at the pH usual for the KstD family of 8.5. Finally, the modeling confirms the origin of the enantioselectivity of C2-H activation and substrate specificity for Δ1-3- ketosteroids.
A topologically chiral catenane that is not topologically chiral
Authors: Pairault Noel , Rizzi Federica , Lozano David , Tizzard Graham , Jamieson Ellen , Goldup Stephen
Published: September 2022

To consider the topology of a molecule its structure is reduced to labelled vertices (the atoms) and edges (bonds between them) to generate a molecular graph . If only covalent bonding interactions are included , , such graphs are like the structural diagrams commonly employed to describe molecules, except that in topological terms, atomic geometry is largely irrelevant; most molecules can be represented as a two-dimensional network and most covalent stereogenic units are topologically irrelevant. In 1960, Wasserman synthesized a molecule in which two rings are held together like in a chain, which is a topological isomer of the separated components, leading to the realization that molecules could be topologically non-trivial. This insight found wider implications in biochemistry and materials science but also led to the assumption that the stereochemistry of chiral catenanes is inherently topological in nature. We show this is incorrect by synthesizing an example whose stereogenic unit is identical to previous reports but whose stereochemistry is Euclidean. Thus, we can unite the stereochemistry of catenanes with that of their topologically trivial cousins, the rotaxanes, paving the way for a unified approach to their discussion.

Published: September 2022

Nanoparticle surfaces are passivated by surface-bound ligands, and their adsorption on synthesized nanoparticles is complicated because of intricate and low-symmetry surface structures. Thus, it is challenging to precisely investigate ligand adsorption on synthesized nanoparticles. Here, we applied a machine-learning-accelerated ab-initio calculation into experimentally resolved 3D atomic structures of Pt nanoparticles to analyze the complex adsorption behavior of polyvinylpyrrolidone (PVP) ligands on synthesized nanoparticles. Different angular configurations of the large-sized ligands are thoroughly investigated to understand adsorption behaviors onto the various surface-exposed atoms with intrinsic low-symmetry. It is revealed that long-range van der Waals interaction (EvdW) shows weak negative relationship against generalized coordination number (-CN-), in contrast to the positive relationship in short-range direct bonding (Ebind), which attenuates the correlation between ligand binding energy (Eads) and -CN-. In addition, the PVP ligands favor to adsorb at which the long-range vdW interaction with surrounding surface structure is maximized. Our results highlight the significant contribution of vdW interactions and importance of local geometry of surface atoms to adsorption behavior of large-sized ligands on synthesized nanoparticle surfaces.
Hierarchical organization of structurally colored cholesteric phases of cellulose via 3-d printing

Published: September 2022

Structural color—a widespread phenomenon observed throughout nature is caused by light interference from ordered phases of matter. While state-of-the-art nanofabrication techniques can produce structural organization in small areas, we still lack a cost-effective, and scalable techniques to generate tunable color at sub-micron length scales. In this work, we produced structurally colored hydroxypropyl cellulose filaments with a suppressed angular color response by 3-d printing. Our systematic study of the morphology of the filaments reveals the key stages in the induction of a two-degree hierarchical order through 3-d printing. The first degree of order originates from the changing of the cholesteric pitch at a few hundred nm scale via chemical modification and tuning of the solid content of the lyotropic phase. Upon 3-d printing, the secondary hierarchical order of periodic wrinkling was introduced through the Helfrich-Hurault deformation of the shear-aligned cholesteric phases. Our work reveals the mechanism of the wrinkling behavior evidenced by detailed morphological characterization using SEM. In single layered filaments, we identified four morphological zones with varying order of wrinkles. Through this work, we demonstrate the possibility of modifying the wrinkling behavior and thus the angle dependence of the color response by changing the printing conditions.

Published: September 2022

Shale gas exploration generates methane, mostly used as fuel, and natural gas liquids (NGLs), mainly used as chemical feedstocks. These NGLs are typically extracted using expensive turbo-expansion and cryogenic distillation unit operations and an alternative modular approach using a solid-state electrochemical reactor configuration is proposed. This electrochemical approach offers advantages over other process intensification techniques due to its modularity and potential delivery of an electric by-product. In this study, a solid oxide cell setup using rare-earth and alkali-earth based perovskites – LaFeO3 and SrFeO3 – was demonstrated for thermally efficient dehydrogenation of NGLs to generate olefins for downstream chemical production. This demonstration showed that ethane conversion via oxidative dehydrogenation (up to 0.1 mmol/min/cm2 of ethylene) was significant in comparison to thermal cracking (up to 0.01 mmol/min/cm2 of ethylene) under the conditions tested and illustrates the viability of this approach to process intensification. Furthermore, modifications to the current cell configuration are needed before the electric by-product can be generated.

Health care professionals are ageing, and there is a severe, global need to attract future employees. This study examines the construction of employer brand image among young health care professionals, and related elements. The qualitative research data were collected through email and personal interviews from young nursing and physician students. The analysis results indicate that organisations can affect their employer brand image for future employees through supportive working culture and human resource practices as well as direct marketing actions. The marketing and human resource practices targeted towards young health care professionals are underused. The results can help health care organisations in planning recruitment and marketing processes according to young health care professionals' expectations. This study integrates human resource management research and marketing research relating to employer branding and recruitment.

This paper reviews the existing research on sustainability and sustainable development around the world. It begins by defining the sustainability and sustainable development concepts. Thereafter, the paper highlights the dimensions of sustainable development and sustainability based on the literature. The paper also shows the relationship between sustainability and sustainable development. The paper used the literature review methodology. The paper finds that each region of the world has made some progress towards achieving high levels of sustainable development; however, each region also faces unique challenges that affect the attainment of the sustainable development goals in the region. These challenges have social, political,structural, institutional and economic dimensions. Also, while sustainable development is a widely acknowledged concept in academia its practicality in policy circles has been contested. Existing empirical studies show that incorporating sustainability or sustainable development concerns into business or environmental management yields some positive benefits. Finally, some areas for future research are suggested.

Salah satu keuntungan dari penggunaan beton dan baja tulangan mutu tinggi pada bangunan gedung bertingkat adalah dapat mereduksi ukuran komponen struktur seperti balok, kolom, dan dinding geser. Akan tetapi, semakin tinggi kekuatan tekan beton, maka semakin getas beton tersebut. Untuk mereduksi sifat getas beton mutu tinggi, material fiber (serat) dapat ditambahkan kedalam beton mutu tinggi. Salah satu jenis serat yang dapat ditambahkan kedalam beton adalah steel fiber (serat baja). Beton dengan serat dapat disebut Fiber Reinforced Concrete (FRC) atau Fiber Reinforced Cementitious Composite (FRCC). Highly-Flowable Strain Hardening Fiber Reinforced Concrete (HF-SHFRC) adalah salah satu perkembangan teknologi beton dengan serat. HF-SHFRC memiliki sifat Self-Compacting Concrete (SCC) sebelum mengeras, dan memiliki kemampuan tensile strain-hardening ketika sudah mengeras. Paper ini mempresentasikan hasil peneitlian mengenai perilaku tarik material HF-SHFRC, dan aplikasi material HF-SHFRC pada kolom beton bertulang mutu tinggi dan hubungan balok-kolom eksterior yang sudah dilakukan oleh peneliti sebelumnya. Dengan menggunakan material HF-SHFRC pada elemen struktur beton bertulang, elemen struktur dapat meningkatkan kekuatan geser, daktilitas, disipasi energi, dan toleransi kerusakan. Selain itu, di dalam HF-SHFRC, material sementisius pengganti semen digunakan dalam jumlah besar, yaitu 50%. Penggunaan material sementisius pengganti semen dalam jumlah besar menunjukkan bahwa HF-SHFRC ramah lingkungan dan memenuhi kriteria sebagai material berkelanjutan.

Dalam satu dekade terakhir, belum banyak ditemukan penelitian yang membahas tentang kemajuan penggunaan Internet of Things (IoT) di industri konstruksi Indonesia. Di era industri 4.0 seperti sekarang ini, dibutuhkan sebuah penelitian untuk mengetahui perkembangan IoT di industri konstruksi baik di Indonesia maupun di luar negeri, dan mengetahui kesenjangan di antaranya. Penelitian ini dilakukan menggunakan metode bibliometrik dengan software Publish or Perish 7. Data akan dikelompokkan dalam lima ranah pada industri konstruksi yang sangat terpengaruh dengan masuknya IoT yaitu: construction safety, machine control, site management, fleet management dan project management. Dari penelitian didapati bahwa Cina merupakan negara dengan kemajuan penggunaan IoT paling pesat dimana ranah yang paling banyak dibahas adalah terkait construction safety. Sementara itu, penerapan IoT di industri konstruksi di Indonesia baru dimulai dalam beberapa tahun terkakhir, yang ditandai dengan masih sedikitnya karya ilmiah yang terkait penerapan IoT di industri konstruksi. Pemerintah Indonesia juga masih belum berinvestasi pada sektor penelitian dan pengembangan sebanyak negara lain yang ditinjau. Temuan ini diharapkan mampu menjadi basis dalam menginisiasi penerapan IoT di industri konstruksi Indonesia.
