The Mini Nutritional Assessment tool’s applicability for the elderly in Ethiopia: validation study
Authors: Urgessa Megersso 
Published: November 2022

Background
The Mini Nutrition Assessment (MNA) is a widely used and valid tool for screening and assessment of malnutrition among the elderly population worldwide. However, MNA has not been validated among the Ethiopian elderly population and this study assessed the validity of the tool for the target population.

Methods
Cross-sectional validation study design employed to validate MNA in Meki town, East Ethiopia. This study included 176 randomly selected elders living in the community, whereas amputated, bedridden, visible deformity, known liver and/or renal disorders were excluded. The original MNA questionnaires were translated to local language and administered to each participant after doing the pretest. The anthropometric, self-perception of nutritional status and serum albumin concentrations were measured. Reliability, validity, sensitivity, specificity, Positive Predictive Value (PPV), and Negative Predictive Value (NPV) were calculated. Receiver-operating characteristic (ROC) curve analysis was plotted to identify the area under the curve (AUC) and optimal cut-off value for the prediction of malnutrition.

Result
A total of one hundred and seventy-six elders participated in this study. Of the total participants, 78(44.3%) were males. The mean (SD) age of the participants was 67.6 (±5.8) years and ranged from 60 to 84 years. The prevalence of malnutrition based on the MNA criteria (MNA < 17 points) was 18.2%, and 13.1% based on serum albumin concentration (<3 g/dl).The MNA had an overall Internal consistency of Cronbach’s alpha 0.61. The tool also demonstrated significant criterion-related validity (0.75, p < 0.001) and concurrent validity (0.51, p < 0.001) with serum albumin concentration and self-perception of nutritional status respectively. Using the original cut-off point, the sensitivity, specificity, PPV and NPV of the tool were 93.5%, 44.6%, 65.4% and 86.0%, respectively. By modifying, the cut-off point to a value of <20.5, the sensitivity and specificity of the tool increases to 97.6% and 82.8% respectively. The AUC (95%CI) showed an overall accuracy of 92.7% (88.5, 96.9).

Conclusion
The MNA tool can be used as a valid malnutrition screening tool for the Ethiopian elderly population by modifying the original cut-off point.

Published: November 2022

The fate of extra carbon accessing soil under elevated CO2 levels, as well as the repercussions for plant nutrition, is primarily determined by soil microbe activity. However, most increased CO2 research has reported changes usually increases in soil organic carbon and reduction in the pH of the soil which is merely the first step in understanding how soil processes are altered. We analyzed these variables by assessing enzyme activities and identifying the individual components impacted by high CO2 and those that reflect changes in soil organic matter pools. The majority of the microbial variables studied showed a significant increase under eCO2 conditions, The rise in dehydrogenase activity suggests that the increased biomass of bacteria coincided with an increase in their activity. The rise in phosphatase activities implies that organic matter breakdown is being stimulated overall. The sulphur fractions had a significantly increased number of substrates consumed by soil microorganisms under increasing CO2. Moreover, direct examination of data from these perspective steep shifts in soil biological activity points to possible areas of investigation.
Langmuir–Blodgett Films
Authors: Caseli Luciano 
Published: November 2022

Abstract

Langmuir–Blodgett
(
LB
) films, one of the earliest examples of innovative materials, provide the opportunity to control the structure of thin films at the molecular level. In this method, a single layer of molecules is first organized on a liquid surface, usually water, before being transferred onto a solid support to form a thin film whose thickness is monomolecular. If the process is repeated, multilayered films can be prepared. The layer of molecules on a liquid surface is termed a
Langmuir monolayer
, and after transfer to a solid support that intercepts the monolayer vertically, it is called a
Langmuir–Blodgett film
. The ability to control the thickness of an organic film at the molecular level and control the placement of molecules in multilayer assemblies forms the basis of many ‘smart’ applications of LB films. Applications include electronics, optics, microlithography, chemical sensors, biosensors, and biochemical probes. We cite through the text many comprehensive articles and books on the issue.

Published: November 2022

Abstract
Additive manufacturing (AM), or 3D printing, has seen exponential growth in the past two decades, with more new techniques emerging and new materials available. AM was first established as an efficient technology for prototyping about four decades ago. Today, it is widely used in a variety of industries, including healthcare, automotive, aerospace, defense, and so on. Whilst AM is a general term, it consists of multiple drastically different techniques that need different forms of feedstock materials and processing conditions. This article reviews the current prevailing AM technology for polymers with a brief history, and then a focus on technological details, available materials, and the latest development for each method. The challenges and trends of AM toward next‐generation advanced manufacturing are also highlighted.

Published: November 2022

AbstractHollow multishelled structure (HoMS) is a promising multi‐functional platform for energy storage, owing to its unique temporal‐spatial ordering property and buffering function. Accurate co‐control of its multiscale structures may bring fascinating properties and new opportunities, which is highly desired yet rarely achieved due to the challenging synthesis. Herein, a sequential sulfidation and etching approach is developed to achieve the delicate co‐control over both molecular‐ and nano‐/micro‐scale structure of WS2−x HoMS. Typically, sextuple‐shelled WS2−x HoMS with abundant sulfur vacancies and expanded‐interlayer spacing is obtained from triple‐shelled WO3 HoMS. By further coating with nitrogen‐doped carbon, WS2−x HoMS maintains a reversible capacity of 241.7 mAh g−1 at 5 A g−1 after 1000 cycles for sodium storage, which is superior to the previously reported results. Mechanism analyses reveal that HoMS provides good electrode–electrolyte contact and plentiful sodium storage sites as well as an effective buffer of the stress/strain during cycling; sulfur vacancy and expanded interlayer of WS2−x enhance ion diffusion kinetics; carbon coating improves the electron conductivity and benefits the structural stability. This finding offers prospects for realizing practical fast‐charging, high‐energy, and long‐cycling sodium storage.

AbstractK2NiF4‐type Ba–Li oxyhydride (BLHO) transitions to a so‐called hydride superionic conductor, exhibiting a high and essentially temperature‐independent hydride ion (H−) conductivity over 0.01 S cm−1 through the disordering of H− vacancies above 300 °C. In this study, a Ba–Li–Na–H–O oxyhydride system synthesized in which lithium is partially substituted with sodium in BLHO and investigated the effects of Na content on the phase transition behavior and the conductivity. Structural refinements and differential scanning calorimetry experiments confirmed a lowering trend in the phase transition temperatures and decreasing enthalpy changes for the transition with increasing Na content. Substitution of not <40% of Li with Na lowered the degree of ordered vacancies at the H− sites at room temperature and improved conductivities by more than two orders of magnitude in the low‐temperature region (T < 300 °C) before the phase transition. These findings clearly show that introducing Na into the lattice effectively stabilizes the high‐conductive phase of BLHO.

AbstractBased on the difference in the reaction rate of different groups of urea‐formaldehyde resins and isocyanate resins, this study designed two different urea‐formaldehyde resins: a normal urea‐formaldehyde resin (UF) and one with high mono‐hydroxymethylurea content (UF*) to react with polymeric methylene diphenyl diisocyanate (pMDI) resin. The difference in mono‐ and di‐hydroxymethyl urea content between UF and UF* resins was analyzed by nuclear magnetic resonance (NMR) spectroscopy, and results showed that the mono‐hydroxymethyl urea content of the UF* resin was much higher than that of the conventional UF resin. The fourier transform infrared spectrometer (FTIR) analysis of differences between UF* and UF resin showed that the UF* process did not change the main structure of the conventional urea formaldehyde resin. Differential scanning calorimeter (DSC) analysis showed that the curing temperature of the hybrid UF*‐pMDI resin was reduced 27.3°C compared to that of the UF‐pMDI resin. When these hybrid resins were used to bond plywood respectively, test results showed that the UF*‐pMDI resin improved the dry and wet bonding strength by 2.6% and 3.9%, respectively, compared with the UF‐pMDI resin under the condition of hot pressing time (3 min) and temperature (140°C), meeting the requirement of Chinese standard of GB/T 9846–2015 for Class III board. This study provides a new path for further improving the performance and design of hybrid resins based on isocyanate and urea‐formaldehyde resin.

Published: November 2022

AbstractPolyacrylonitrile (PAN)‐based composite nanofibers incorporated with high‐percentage inexpensive pitch were successfully prepared by a simple electrospinning technique. Low‐softening‐point naphthalene pitch (NP) has the merit of high solubility but inevitably brings about preoxidation problem. Thus the influence of different preoxidation strategies on the morphology, composition, and structure of composite nanofibers was systematically investigated. The results show that there exists a ternary phase diagram consisting of PAN‐pitch‐solvent and a suitable apparent viscosity of homogeneous solution, which favors the smooth electrospinning and good adjustment for the diameter of carbon nanofibers (100–500 nm). The crystallinity, crystalline order, and electrical conduction of composite nanofibers are enhanced by incorporating graphitizable NP, for example, the electrical resistance of 50% NP‐PAN composite nanofiber films after 800°C carbonization decreases about 30%. Both increasing the oxidation temperature and extending the oxidation time are beneficial to the oxidative stabilization of composite nanofibers with a suitable NP percentage below 50%. Gradient heating (240–340°C) and pressurized (0.08 MPa) preoxidations could accelerate the oxidative stabilization of composite nanofibers with a high NP percentage up to 110% and significantly shorten the oxidation time by half. Therefore, this study paves the road for facile preparation of cost‐competitive carbon nanofibers with controllable morphology, structure, and properties.
Einfamilienhaus? Du darfst – Die Typologie des kompakten Hofhauses ermöglicht private Wohnformen auf eigenem Grund bei hoher urbaner Dichte

Published: November 2022

AbstractDas sog. kompakte Hofhaus wurde als neuartiger Hofhaustyp an der Hochschule für Technik Stuttgart (HFT) entwickelt und untersucht. Zu Quartieren addiert stellt er den Bewohnern bei geringem Landverbrauch urbane Lebensräume zur Verfügung und kann hohe Dichte, Diversität von Nutzung sowie ein hohes Maß an Privatheit und Wohnqualität in Innen‐ wie Außenräumen miteinander vereinen – in Neubau‐ wie in Bestandsituationen. Definitionsgemäß wird dies dadurch erreicht, dass nicht einsehbare Höfe/Außenräume als ausschließlich private Nutzflächen in die Gebäudestruktur integriert werden (anstelle von exponierten Abstandsflächen mit geringerem Nutzwert außerhalb des Gebäudes) und über diese Bereiche auch die Belichtung und die Belüftung erfolgen können. Innen‐ und Außenräume können so zu einem geschützten und eng miteinander verzahnten Lebensraum verschmelzen. Die bisherigen Ergebnisse der seit 2017 laufenden DFG‐geförderten interdisziplinären Forschungsarbeit weisen mit einer umfangreichen Typologie, allgemeingültigen Lösungsstrategien und vielen Einzeluntersuchungen nach, dass dieser Ansatz bereits auf ungewöhnlich kleinen Parzellen (ca. 60–200 m2) unterschiedlicher Proportion mit bis zu fünfgeschossigen Gebäuden für eine oder mehrere Parteien funktioniert. Einige der aus verschiedenen Grundtypen hervorgehenden Varianten eignen sich als Einfamilienhäuser auf eigenem Grund und können so diese von der Mehrheit angestrebte Wohnform in einem nachhaltigen urbanen Umfeld hoher Dichte und Heterogenität ermöglichen.

AbstractBackgroundBariatric surgery can be effective in weight reduction and diabetes remission in some patients, but is expensive. The costs of bariatric surgery in patients with obesity and type 2 diabetes mellitus (T2DM) were explored here.MethodsPopulation-based retrospectively gathered data on patients with obesity and T2DM from the Hong Kong Hospital Authority (2006–2017) were evaluated. Direct medical costs from baseline up to 60 months were calculated based on the frequency of healthcare service utilization and dispensing of diabetes medication. Charlson Co-morbidity Index (CCI) scores and co-morbidity rates were measured to compare changes in co-morbidities between surgically treated and control groups over 5 years. One-to-five propensity score matching was applied.ResultsOverall, 401 eligible surgical patients were matched with 1894 non-surgical patients. Direct medical costs were much higher for surgical than non-surgical patients in the index year (€36 752 and €5788 respectively; P &lt; 0·001) mainly owing to the bariatric procedure. The 5-year cumulative costs incurred by surgical patients were also higher (€54 135 versus €28 603; P &lt; 0·001). Although patients who had bariatric surgery had more visits to outpatient and allied health professionals than those who did not across the 5-year period, surgical patients had shorter length of stay in hospitals than non-surgical patients in year 2-5. Surgical patients had significantly better CCI scores than controls after the baseline measurement (mean 3·82 versus 4·38 at 5 years; P = 0·016). Costs of glucose-lowering medications were similar between two groups, except that surgical patients had significantly lower costs of glucose-lowering medications in year 2 (€973 versus €1395; P = 0.012).ConclusionBariatric surgery in obese patients with T2DM is expensive, but leads to an improved co-morbidity profile, and reduced length of hospitalization.
Indonesia toward sustainable agriculture – Do technology‐based start‐ups play a crucial role?
Authors: Prihadyanti Dian , Aziz Subkhi Abdul 
Published: November 2022

AbstractThis paper explores the role of technology‐based start‐ups in supporting the implementation of sustainable agriculture (SA) practices in Indonesia. Through a qualitative multiple‐case studies research strategy, this research identifies several roles of start‐ups in implementing SA. The start‐ups create sustainable archetypes mainly for the economic and social aspects, but not all of them penetrate the environmental side. Start‐ups can contribute to the agricultural system in three ways: (1) focus on solving fundamental problems, (2) focus on solving fundamental problems and providing strategic solutions, and; (3) focus on providing advanced solutions. In the implementation mechanism, the start‐ups experienced various risks from the natural environment, the internal environment, or other actors—especially producers—due to dependencies. The disappearance of start‐ups from the agriculture system or the inhibition of their business can reduce or hinder the implementation of SA practices. Regarding the debate concerning the necessity of government support for start‐ups to achieve sustainability, this paper argues that government support is still needed in a situational just‐in‐time manner.

Published: November 2022

AbstractNonalcoholic steatohepatitis (NASH) is characterized by massive lipid deposition in hepatocytes and is often associated with hepatic inflammation and other severe metabolic syndromes. The intervention of NASH can prevent its further progression into hepatocarcinoma. In this study we have successfully constructed liver‐targeted Ce‐based hollow mesoporous nanocarriers loaded with bioactive drugs. This may provide an effective approach for eliminating NASH. Liver‐section‐specific targeting was realized by covalently linked galactose (Gal), which can be specifically recognized by receptors in the membranes of hepatocytes. Meanwhile, resveratrol (Res), a drug used to treat NASH, was efficiently loaded into the pores and cavity of CeO2 (Res@H−CeO2−Gal). In steatotic HepG2 cells (free fatty acid induction), this nanosystem was found to enhance cellular Res internalization for improved anti‐lipogenesis activity. In mice with NASH, Res@H−CeO2−Gal increased Res delivery to liver sections for a reduction in lipid accumulation and enhanced anti‐inflammatory activity from the antioxidant capacity of Ce‐based nanocarriers. This effectively recovered NASH mice to the normal state. These findings show that the hepatic targeting and Res delivery nanoplatform could act as a safe and promising strategy for the elimination of NASH and other liver diseases.
