Ética e pesquisa com pessoas com deficiência: do domínio por tutela à contraconduta
Authors: Pieczkowski Tania Mara Zancanaro , Gräff Patrícia
Published: October 2024

Este artigo objetiva tensionar a pesquisa com pessoas com deficiência, a partir do conceito de domínio por tutela, tomando a contraconduta como possibilidade de enfrentamento aos procedimentos de condução das condutas dos outros, inscritos, historicamente, na esteira das práticas de exclusão. Toma um conjunto de estudos que envolvem a ética na pesquisa com pessoas com deficiência, aliado a três pesquisas de Mestrado em Educação, produzidas por pessoas com deficiência, como superfície analítica, a partir do campo dos Estudos Foucaultianos. As análises mostram um afastamento das pessoas com deficiência de alguns exercícios de domínio por tutela, na pesquisa em Educação, sobretudo pela contraconduta que empreendem aos modos padronizados de exercer a pesquisa. Com isso, na atualidade, as pessoas com deficiência ocupam tanto a posição de participantes da pesquisa como de pesquisadores que, com as suas produções, contribuem para que a área da Educação avance na constituição de melhores condições para a inclusão, evidenciando seu protagonismo e contribuindo para a proposição de políticas de inclusão e de reconhecimento da diferença como uma questão ética, como uma forma de estar no mundo.
O RACISMO AMBIENTAL PRATICADO CONTRA OS POVOS INDÍGENAS NO RIO GRANDE DO SUL
Authors: Zago Thomasi Tanise , Sousa Santos Ariel , Gonçalves Cavalcanti Dias Clara Angélica
Published: October 2024

Os eventos climáticos extremos afetam pessoas, grupos e comunidades de maneira desigual, visto que o racismo ambiental promove discriminações por razões de raça, gênero e classe, atribuindo uma maior carga dos problemas socioambientais aos mais vulneráveis, como os indígenas. As violências contra esses povos e a falta de delimitação e demarcação de terras indígenas são problemas agravados pelo racismo ambiental, que se intensificou com as enchentes que atingiram o estado do Rio Grande do Sul, em 2024. Desse modo, esta pesquisa justifica-se por sua relevância para o meio acadêmico, sociedade e Estado, que têm um interesse comum em buscar soluções exequíveis. No que concerne ao objetivo deste artigo, analisar-se-á o racismo ambiental praticado em desfavor dos povos indígenas no Rio Grande do Sul durante as fortes chuvas que acometeram a região, com o fito de propor ações emergenciais e estruturais direcionadas a esses indivíduos, além de indicar possíveis alternativas para proteger a dignidade humana. À guisa de conclusão, utilizar-se-á a natureza de pesquisa básica, o procedimento será técnico-bibliográfico, a forma de abordagem do problema será qualitativa e os objetivos da pesquisa serão descritivos-explicativos, debatendo os temas por meio da literatura pertinente.

Książka dotyczy ważnej problematyki naukowej recepcji „Kultury”. Wypełnia ona lukę badawczą zwłaszcza wobec przyjętej przez autora perspektywy łączącej analizy historyczne, medioznawcze i politologiczne. Jest aktualna ze względu na zainteresowanie koncepcjami wschodnimi Jerzego Giedroycia jako potencjalnymi kierunkami zwrotu w obecnej polityce.
Z recenzji prof. Iwony Hofman
Najważniejszym dokonaniem autora recenzowanej książki jest rekonstrukcja istotnego osiągnięcia środowiska „Kultury”, czyli wypracowanego przez niego zarysu polityki wschodniej, jaką powinna przyjąć przyszła niezależna i demokratyczna Polska. Równie istotne, a może jeszcze ważniejsze i na pewno bardzo nowatorskie, jest zderzenie zarysowanej teorii z praktyką polityczną.

Authors: Balaganesan M. , Shanmugam S.A. , Kathirvelpandian A. , Agarwal Deepak , Ramya R. , Suresh E.
Published: October 2024

Background: Accurate identification of freshwater fish is essential to preserving freshwater fish diversity. BLOG uses a short DNA sequence taken from a portion of mitochondrial DNA called Cytochrome C Oxidase subunit I (COI), which varies by several percent, even between closely related species, so it can be used to identify the species of a particular individual. Methods: BLOG 2.0 is an advancement of logic data mining and can identify nucleotide positions that characterize DNA barcode sequences and classify species using logic formulas. This character-based identification method identifies specimens to species with the help of their logic rules and diagnostic nucleotides in the selected gene sequences. In this study, 30 species distributed in the Indian freshwater region were taken as the target group. A 30 -110 mtCOI sequences for each species were downloaded and modified. Results: With the help of BLOG.2.0 software, to identified specific diagnostic nucleotides for these freshwater species. Species-specific probes ranging from 18-22 base pairs were designed based on identified diagnostic nucleotide sites that could be useful in customized microarrays (DNA chips). This BLOG based CBIS will be a promising technique for obtaining quick, convenient, and extensive knowledge about the conservation of various freshwater fishes and their forensic applications.

Authors: Ganapathi S. , Dhanapal G.N. , bai S. Kamala , Ajmal K.K.
Published: October 2024

Background: The cropping systems in any agro-ecological zone in the globe are driven by a number of critical issues, including rising food demands, the depletion of land and the degradation of land resources. The goal of traditional cropping methods has been to maximise crop yields. Cropping systems that take into account the new social, economic and ecological or environmental considerations are urgently needed nowadays. Due to their adaptability to diverse cropping patterns and capacity to fix nitrogen, legumes can offer prospects for continuous increases in productivity. Legume-based crop rotations help to maintain of organic matter, increase of soil nitrogen, nutrient balance, maintenance of soil physical qualities and disruption of soil-borne disease cycles. Conservation tillage is centered on minimum tillage, permanent raised beds, zero tillage with low soil disturbance and the preservation of protective plant cover or plant residues on the soil surface to prevent soil losses, stimulate microbial population and retain moisture and nutrients. Methods: Field experiment were conducted during 2019-20 and 2020-21 at the Main Research Station (MRS), GKVK, University of Agricultural Sciences, Bangalore On sandy loam soil to study the performance of Weed management in maize-based cropping system in conservation agriculture. The experiment was laid out under split plot design with five main plots on different tillage treatments i.e., Conventional tillage, Zero Tillage, Minimum Tillage, Minimum Tillage and Permanent raised bed and three sub plots of different weed management practices i.e., Chemical weed management practices, Integrated weed management practices and Unweeded Control replicated thrice. Result: Among tillage practices, permanent raised bed recorded the least total weed density and weed dry weight at harvest when compared to other tillage practices and also high seed yield, haulm yield and B: C ratio due to less weed infestation, good root growth, adequate aeration and nutrient availability compared to other tillage practices. Permanent raised beds had significantly higher nitrogen, phosphorus and potassium uptake than zero tillage. Among weed, management practices, Integrated weed management (Pendimethalin-750 g/ha (PE) + Hand weeding at 30 DAS) recorded the least total weed density and weed dry weight at harvest compared to unweeded treatment and also high seed yield, haulm yield and B: C ratio due to less weed infestation, compared to unweeded treatment. Integrated weed management resulted in significantly higher nitrogen, phosphorus and potassium uptake compared to unweeded (control).

La información del diagnóstico participativo, complementada con fuentes documentales, permitió una aproximación al panorama ambiental local. Esto facilitó el desarrollo de una serie de guías y la proyección de un escenario de interpretación ambiental que aborda el contexto natural y socio-cultural del municipio, promoviendo la apropiación del conocimiento ambiental desde una mirada crítica, en un territorio altamente amenazado por la degradación ambiental y con problemáticas sociales complejas como las existentes en el Magdalena Medio.
Proteins of the future: a bibliometric study of alternative food acceptance
Authors: Osorio-Andrade Carlos Fernando , Arango-Pastrana Carlos Alberto , Candelo-Viáfara Juan Manuel
Published: October 2024

The present study aimed to evaluate the state of research linking alternative proteins with consumer attitude and behavior, through a bibliometric analysis of 265 documents indexed in Scopus. The methodology involved the identification of descriptive indicators such as temporal evolution of publications, journals, authors and most cited documents. A qualitative content analysis was also carried out to determine research designs, data sources and predominant analysis techniques. The results show an exponential growth of publications since 2018, with majority contributions from Europe and North America. In terms of methodological aspects, quantitative and empirical survey-based studies predominate. The literature linkage evidenced three streams: overcoming cultural barriers towards edible insects, factors predicting general acceptance of alternative proteins, and acceptance drivers specifically for plant-based meat substitutes. Future research opportunities include the need for more comparative studies across countries and population segments, experimentation with communication and packaging strategies, forms of gradual insertion into the diet, and analysis of microbial and fungal protein sources.

The ecology and distribution of P. poligraphus were investigated in several artificial spruce stands located along the Apennines. Results suggest that, in certain conditions, this species may play an active role, together with other bark beetles, in the decline of the Norway spruce Picea abies. Interestingly, in some spruce sites such as Abetone and Pratomagno, P. poligraphus was observed to colonize not only thin-diameter branches but also larger stems, being able to occupy various ecological niches on its host plants. Our findings highlighted that, this beetle, hitherto known in Italy only for some Alpine sites, was able to “follow” Picea abies in spruce formations along the Apennine ridge. That occurred in different as well as very distant and disjunct environments, with the site of Montedimezzo in “Alto Molise” (Isernia) representing the southernmost record in Italy. Moreover, Danielozyma ontarioensis a saprophyte ascomycetous yeast frequently isolated from this insect and other fungi such as Penicillium glabrum, Talaromyces rugulosus, Beauveria bassiana and Ophiostoma piceae species complex may be associated with this beetle.

Моделирование условий режимов размыва плотины при переливе воды через еe гребень
Authors: Rozov Andrei Leonidovich , Rusina Nadezhda Yur'evna , Kolpakov Dmitrii Andreevich
Published: October 2024

Работа направлена на определение критериев режимов размыва плотин при переливе потока воды через еe гребень. Известно, что при натурных катастрофах при переливе потока воды через гребень плотины наблюдается пространственный размыв плотин, когда на какой-то небольшой части гребня образуется начальный проран. Продолжающийся перелив воды приводит к размыву дна начального прорана. По достижению дном прорана основания плотины изливающийся из водохранилища поток воды начинает размывать боковые стенки прорана. Процесс размыва завершается после опорожнения водохранилища с образованием конечного прорана, составляющего только часть (часто небольшую) тела плотины. В то же время в экспериментальных исследованиях перелив потока воды через гребень плотины приводит к плоскопараллельному размыву модели плотины -- равномерному размыву по всей длине напорного фронта с практически полным разрушением тела плотины. В работе исследуются причины этого различия. На основе математической модели выводятся предварительные условия реализации различных режимов размыва плотин, подтверждeнные специально проведeнными экспериментами, а также известными экспериментальными и натурными данными по разрушению плотин.

Abstract. Introduction. The burden of cardiovascular disease, diabetes mellitus, and the associated mortality remains high. One classification system that predicts the development of cardiovascular events and type 2 diabetes mellitus is Cardiometabolic Disease Staging (CMDS). The study of new cardiometabolic profile parameters is relevant in the context of their association with residual cardiovascular risk. The aim of the study was to evaluate the cardiometabolic profile, including extended parameters, in young adults, while taking into account the CMDS. Materials and Methods. 185 male and female subjects aged 35.0 [30.0–39.0] years were examined. The participants were divided into groups according to the CMDS classification: Stage 0, metabolically healthy; Stage 1 (low risk), one or two risk factors (RFs) other than prediabetes; Stage 2 (intermediate risk), presence of ≥3 risk factors or prediabetes; Stage 3 (high risk), presence of ≥3 risk factors and prediabetes. The study examined visceral adiposity index, visceral fat level, insulin resistance, leptinemia, hyperuricemia, glomerular filtration rate, C–reactive protein, and N–terminal brain natriuretic peptide concentrations. The data were processed in SPSS Statistics 26. Results and Discussion. The cardiometabolic profile demonstrated unfavorable alterations with the progression of CMDS stages. Across the spectrum from CMDS 0 to CMDS 3, we observed a significant rise in the prevalence of abdominal obesity (0% to 100%, p<0,001), body mass index ≥25 kg/m2 (16.2% to 100%, p<0.001), and excess visceral fat level (0% to 23.8%, p<0.001). Simultaneously, the prevalence of hypercholesterolemia demonstrated a significant rise (24.3% to 52.4%, p=0.025), as did elevated low–density lipoprotein cholesterol (32.4% to 76.1%, p=0.014), insulin resistance (2.7% to 66.7%, p<0.001), leptinemia (45.9% to 90.5%, p=0.009), C–reactive protein (2.7% to 57.1%, p<0.001) and hyperuricemia (16.2% to 61.9%, p<0.001). The median values of these parameters also increased. Conclusions. Our data confirm the simultaneous increase in both the quantity and intensity of risk factors, manifestations of adiposopathy associated with increasing residual cardiovascular risk. Our results substantiate the feasibility of using the CMDS classification at the stage of primary prevention of cardiometabolic diseases to identify groups with the most significant metabolism disorders of lipid, carbohydrate and purine metabolism in young adults.

Exploring Impact and Variability of Research Productivity Among Academic Orthopaedic Leaders
Authors: Farooq Hassan , Gaetano Andrew , Shivdasani Krishin , Garbis Nickolas , Salazar Dane
Published: October 2024

Introduction:

Assessing scholarly contributions in academic orthopaedic surgery remains challenging, despite the importance of publication productivity in evaluating academic leaders. The Hirsch (h)-index and its derivative, the m-index, offer objective measures to compare and evaluate publication productivity. The primary aims of this study were to compare h- and m-indices of department chairs and residency program directors of orthopaedic training programs in the United States and assess the association between h-index and program rank.

Methods:

A publicly available Doximity report was used to identify and rank orthopaedic surgery residency programs in the United States. Internet-based searches of institution-specific websites were performed to confirm current department chairs and residency program directors as of January 2024. H-index data were collected from a publicly available database known as Scopus. The m-index was calculated as the quotient of h-index and years in practice. Gender and years in practice were obtained through available biographies on institution-specific websites.

Results:

Department chairs had significantly higher h- and m-indices at both the career and 5-year time intervals compared with program directors. Upon subgroup analysis, department chairs and program directors at top-10 ranked programs had significantly higher h- and m-indices compared with the entire population of department chairs and program directors. Linear regression analyses demonstrated a direct linear association between department chair/program director h- and m-indices and program rank.

Conclusions:

Publication productivity was higher for department chairs than residency program directors. Orthopaedic leaders at top-10 institutions had higher publication productivity compared with those at institutions outside of the top 10, per Doximity rankings. Finally, there is substantial variation in publication productivity of orthopaedic surgeons in leadership roles at academic institutions in the United States.

Clinical Relevance:

This study highlights the publication productivity of orthopaedic surgery department chairs and residency program directors and describes the linear association between publication productivity of academic orthopaedic leaders and program rank. This information can be utilized by those interested in learning more about the publication productivity among academic orthopaedic surgeons across different institutions and can assist those who are involved in the hiring and promotion process at these academic institutions.

The chiral edge current is the boundary manifestation of the Chern number of a quantum anomalous Hall (QAH) insulator. Its direct observation is assumed to require well-quantized Hall conductance, and is so far lacking. The recently discovered van der Waals antiferromagnet MnBi2Te4 is theorized as a QAH in odd-layers but has shown Hall resistivity below the quantization value at zero magnetic field. Here, we perform scanning superconducting quantum interference device (sSQUID) microscopy on these seemingly failed QAH insulators to image their current distribution. When gated to the charge neutral point, our device exhibits edge current, which flows unidirectionally on the odd-layer boundary both with vacuum and with the even-layer. The chirality of such edge current reverses with the magnetization of the bulk. Surprisingly, we find the edge channels coexist with finite bulk conduction even though the bulk chemical potential is in the band gap, suggesting their robustness under significant edge-bulk scattering. Our result establishes the existence of chiral edge currents in a topological antiferromagnet and offers an alternative for identifying QAH states.

Published: October 2024

Diabetic retinopathy (DR) is a prevalent microvascular complication of diabetes. While current clinical treatments focus on later stages of the disease, early intervention is crucial to impede its progression. Essential oils derived from Fructus Alpiniae zerumbet (EOFAZ) have shown promise in protecting against high glucose (HG)-induced Müller cell activation and the development of DR. In this study, we designed a reactive oxidative species (ROS)-responsive drug delivery system (NPSPHE@EOFAZ) to target early DR stages and combat oxidative stress. Our nanoparticles were engineered to detect and respond to elevated oxidative stress levels, effectively transporting EOFAZ into HG-exposed Müller cells. The NPSPHE@EOFAZ formulation exhibited significant efficacy in inhibiting abnormal cell growth, reducing oxidative stress, and alleviating inflammation in these cells. Moreover, in vivo experiments on diabetic mice with DR demonstrated that NPSPHE@EOFAZ mitigated early pathological changes by reducing oxidative stress and inflammation. Additionally, the NPSPHE@EOFAZ formulation minimized pathological damage in vital organs such as the heart, liver, spleen, lung, and kidney. These results highlight the potential of NPSPHE@EOFAZ as a promising antioxidant for early intervention in DR pathogenesis.

Authors: Pan Shuo , Zhou Huaiyu , Wu Shuang , Bai Jingru , Cui Da , Wang Qing , Xu Faxing , Wang Zhenye
Published: October 2024

The primary objective of this investigation was to address the toxicity associated with acetochlor (ACT) through subcritical hydrolysis treatment, assessing the efficacy of this approach in mitigating concerns related to acetochlor's toxicity. Gas chromatography-time-of-flight mass spectrometry (GC × GC-TOFMS), Fourier transform infrared spectrometry (FT-IR), and scanning electron microscopy (SEM) were employed to elucidate distribution patterns, variations in functional groups, and morphological features of the hydrolyzed derivatives of ACT. The hydrolytic transformation pathway and mechanisms of ACT product formation were determined by integrating findings from GC × GC-TOFMS analysis and characterization assessments. The subcritical hydrolysis experiments resulted in the identification of 39 hydrolytic by-products from ACT. The peak hydrolysis rate for ACT was observed at a hydrothermal temperature of 280 °C with a reaction duration of 60 minutes, leading to the complete hydrolysis of toxic by-products. In this study, subcritical hydrolysis technology demonstrated its effectiveness in mitigating the toxicity of ACT, achieving environmentally sustainable treatment, and aiding in the resolution of potential hazards posed by ACT to ecosystems and human health.

Published: October 2024

Meta-inflammation (chronic, low-grade systemic inflammation) is increasingly recognized as an essential link between obesity and the development of various non-communicable diseases. However, large animal models for studying obesity-related meta-inflammation are lacking. Minipigs have great potential as models for human diseases, warranting investigation of the performance of the Göttingen minipig as a model for obesity-associated meta-inflammation. Twenty-six pigs were fed a high fat, fructose, and cholesterol diet (HFFC) or a standard diet (SD) for 103 days, resulting in the HFFC group having a 45% higher body weight and 16% larger abdominal circumference by the end of the experiment. Meta-inflammation was shown in the HFFC group by elevated serum concentrations of the acute phase protein C-reactive protein for more than 60 days during development of obesity, accompanied by increased numbers of circulating neutrophils and monocytes. Additional obesity-related abnormalities included dyslipidemia, hepatosteatosis, and transcriptional changes to genes related to inflammation and metabolism in circulating leukocytes, liver, and visceral adipose tissue (VAT). Notably, transcription of genes related to lipid metabolism, namely ATP-binding cassette subfamily A member 1 (ABCA1) and ATP-binding cassette subfamily G member 1 (ABCG1), was elevated in liver, VAT, and circulating leukocytes (ABCA1 only) in the HFFC group compared to the SD group. Development of obesity was accompanied by endotoxemia, evidenced by a 2.5-fold increase in serum lipopolysaccharide concentration in the HFFC group compared to the SD group, suggesting increased intestinal permeability. In conclusion, the described Göttingen minipig model convincingly links diet-induced obesity, meta-inflammation, and endotoxemia, achieved by short-duration HFFC dieting.

Published: October 2024

This work exhibits a novel method for synthesizing α-MoO3 nanoparticles (NPs) using a convenient recipe that utilizes glycerol and ascorbic acid as polymerizing and green complexing agents. Different analytical techniques, including XRD, FT-IR, TGA, and scanning electron microscopy (SEM), were employed to identify the as-prepared α-MoO3 NPs, and it was used as a catalyst in biodiesel production. Moreover, the TPD experiment was performed to determine the catalyst's acidity strength. The α-MoO3 exhibited high efficiency in producing biodiesel from oleic acid and ethyl alcohol as an oil source and alcohol, respectively. The design of experiments and optimization process were also performed using response surface methodology (RSM) to attain the optimal condition. The influences of several parameters, such as catalyst dosage, reaction time, medium temperature, and alcohol to fatty acid (in molar ratio), were studied. The results demonstrate that at the optimal operating variables of 75°C, 50 min of reaction time, a 30:1 molar ratio of alcohol to oleic acid, and 0.007 g of catalyst, the yield of biodiesel production can approach 85%. Moreover, the obtained results indicated that the catalyst can be efficiently recovered and reused four times without significant loss in its activity.

Authors: Nelwan Martin
Published: October 2024

Purpose
In this research, I investigated the phylogenetic relationships of Schistosoma haematobium clade as well as the relationships of its intermediate hosts.
Results
Nucleotide BLAST revealed that Schistosoma haematobium DQ677664.1 shares 89.83% identity with S. guineensis DQ677663.1, 88.14% identity with S. bovis, and 84.1% identity with S. intercalatum. Schistosoma haematobium is derived from East Africa in Lake Victoria, i.e., Kenya, Tanzania, or Uganda. In this study, it was derived from Kenya. The African mainland S. haematonium and the Indian Ocean Islands S. haematobium have low genetic diversity. Schistosoma haematobium can infect B. truncatus, B. globosus, B. forskalii, B. nasutus, and B. productus. Schistosoma bovis infects B. tropicus. Bulinus wrighti is the same species as B. nasutus in the Indian Ocean Islands. Bulinus wrighti should be named B. nasutus wrighti.
Conclusions
Schistosoma haematobium has low genetic diversity. Schistosoma haematobium came from Kenya. Bulinus wrighti belongs to B. nasutus. It should be named B. nasutus wrighti.

Hygroscopicity promotes condensation
Authors: Wang Zhan-Long , Hu Jun
Published: October 2024

Many substances in nature and human society exhibit hygroscopicity. Nowadays, these hygroscopic substances have been broadly used in various domains, e.g., suppressing condensation and icing, collecting water vapor, electric power generation, indoor dehumidification, vapor-fed photocatalytic water splitting and hydrogen production. Due to its hygroscopicity, it has been believed for hundreds of years that hygroscopic substances reduce surrounding humidity and inhibit condensation. Here, we report a distinct phenomenon where hygroscopic liquids, particularly ethylene glycol, a typical hygroscopic solution, induce spontaneous condensation of surrounding water vapor in confined spaces, forming pure condensed droplet patterns. On hydrophobic surfaces, ethylene glycol droplets spontaneously generate a ring of condensed microdroplets around them, presenting a typical structure of Saturn-ring droplets. On smooth surfaces, a filter paper strip soaked in ethylene glycol can cause obvious condensation on the surface when it approaches the surface and within a certain distance, through the confined hygroscopic condensation effect. By utilizing this phenomenon, we achieve water vapor condensation screen-printing of specific shapes on a fixed surface, which we define as Screen Printing of Condensation Patterns (SPCP). This provides an important approach for controlling water vapor condensation and preparing microstructure of moisture sensitive materials. Additionally, this phenomenon can be used for moisture harvesting without the need for specially designed structured surfaces or complex adsorption and desorption processes, achieving a maximum theoretical condensation rate of 20.7 g/m²·min at 80% relative humidity. This unusual phenomenon not only challenge the traditional understanding of hygroscopic substances, but also introduce a new strategy for precisely controlling water vapor condensation, and exploring various novel applications based on controllable condensation patterns.

Innovations in wearable electronics and soft robotics hinge significantly on the development of stretchable electrodes. However, a persistent challenge lies in balancing high stretchability, functional performance, and strain insensitivity. Traditional methods rely on time-consuming and labor-intensive iterative experiments to navigate a vast parameter space. To overcome this, we establish an integrated workflow merging collaborative robotics, machine learning, and finite element simulations to enable the predictive design of ultrastretchable electrodes with strain-insensitive performance. Initially, an automated pipetting robot generates 286 nanocomposites, and their electrical conductance is assessed to train a support-vector machine regressor. Through 7 active learning loops, we fabricate 146 conductive interlayers to construct an ensemble model of artificial neural networks. Leveraging the prediction model and two-scale simulations, we discover a microtextured conductive interlayer as a strain-stable platform. By evaporating a thin gold layer, we develop an ultrastretchable gold conductor with metal-like conductivity, surpassing 1,000% resistance-insensitive stretchability, and robust durability. Furthermore, electrodepositing Zn and MnO2 on gold conductors enables fabrication of a Zn//MnO2 battery showcasing >300% stretchability and strain-insensitive performance. This machine intelligence-driven approach expedites the multi-parameter optimization of stretchable electrodes, achieving strain-invariant functionalities.
Predicting categorical and continuous outcomes of subjects on the Alzheimer's Disease spectrum using a single MRI without PET, cognitive or fluid biomarkers

Published: October 2024

Modern artificial intelligence (AI) and deep learning (DL) techniques have been remarkably successful in predicting Alzheimer's Disease diagnosis and conversion to dementia. However, more continuous outcome measures such as cognitive assessment are needed for richer diagnosis, prognosis, disease trajectory tracking and cohort enrichment in clinical trials. Currently, subjective, time-consuming and operator-sensitive neurocognitive batteries remain the only viable methods of assessing cognition. Very few successful DL studies exist for predicting continuous measures like cognition; those rare ones typically require multiple expensive molecular neuroimaging modalities, fluid biomarkers and multiple visits. Given that MRI is the most prevalent and clinically available imaging modality, its use for quantifying progression and predicting cognition is of great interest. Yet, MRI alone does not capture clinical heterogeneity effectively and has not proven useful in modern DL models of AD progression.

Here we propose a novel multitask DL strategy leveraging both domain knowledge and large pretrained models. We experiment with transfer learning using pretrained models in imaging like ResNet50; and customizing domain knowledge-informed loss functions and image-derived latent representations. Our objective is to predict cognitive scores using only baseline MRI and demographics, bypassing the need for longitudinal or multimodal data, neurocognitive assessment or specialized neuroimaging analysis skills -- a more practical goal that can be accomplished in most community clinic settings. Specifically, we show that the latent representations of the patient's MRI tuned to the tissue segmentation task are powerful regularization attributes and excellent input features for the cognition prediction task. This knowledge-based multitask implementation of DL vastly outperforms all existing methods including straightforward transfer learning on large pre-trained models, producing high-quality segmentation maps, accurate diagnosis, and both current and future cognitive scores, using a single MRI and demographic data readily available at baseline. This study has deep implications in early diagnosis, prognosis, and clinical trial design.
Assessing the Quality of Care for Knee Osteoarthritis in Singapore: A Cross-sectional Study
Authors: Tan Ren Hao Linus , Goff Anthony J , Lim Chien Joo , Tan Yijia Bryan
Published: October 2024

Introduction
The aim of this study was to assess the self-reported quality of care for people with knee osteoarthritis in Singapore and to explore the associations between participant characteristics and functional outcomes at 1 year in relation to the reported quality of care.
Methods
Patients with knee osteoarthritis completed the osteoarthritis quality indicator (OA-QI) questionnaire between June 2021 and February 2022. The OA-QI includes 17 indicators, with "achievement" defined as a 'Yes' response for each. We calculated individual per-item, overall per-item mean, and per-person achievement rates (%) and explored associations between participant characteristics, achievement rates, and function at 1 year.
Results
A total of 314 participants completed the OA-QI. Referral for physical activity (87.5%) and referral for daily activity aid assessment (15.7%) had the highest and lowest per-item achievement rates, respectively. The overall mean per-item and per-person achievement rates were both 62.2%. Participants educated about steroid injections (adjusted coefficient [95% CI]: 7.23 [1.42–13.04]; p= 0.015) or surgery (adjusted coefficient [95% CI]: 12.65 [5.89–19.40]; p< 0.001) had worse functional outcomes at one year than those who were eligible but not informed. Those not assessed for walking aids and indicating walking issues had poorer outcomes one year later (adjusted coefficient [95% CI]: -9.89 (-19.63, -0.15); p= 0.0470). However, no significant associations were found between per-person achievement rates and 1-year functional outcomes.
Conclusions
The quality of care in Singapore for people with knee osteoarthritis is suboptimal, especially for those needing walking aids and weight loss assistance. However, the quality of care alone does not fully account for long-term outcomes, suggesting that other factors need to be considered.
