Bacterial diversity could contribute to the diversity of tuberculosis infection and treatment outcomes observed clinically, but the biological basis of this association is poorly understood. The aim of this study was to identify associations between phenogenomic variation in Mycobacterium tuberculosis and tuberculosis clinical features. We developed a high-throughput platform to define phenotype-genotype relationships in M tuberculosis clinical isolates, which we tested on a set of 158 drug-sensitive M tuberculosis strains sampled from a large tuberculosis clinical study in Ho Chi Minh City, Viet Nam. We tagged the strains with unique genetic barcodes in multiplicate, allowing us to pool the strains for in-vitro competitive fitness assays across 16 host-relevant antibiotic and metabolic conditions. Relative fitness was quantified by deep sequencing, enumerating output barcode read counts relative to input normalised values. We performed a genome-wide association study to identify phylogenetically linked and monogenic mutations associated with the in-vitro fitness phenotypes. These genetic determinants were further associated with relevant clinical outcomes (cavitary disease and treatment failure) by calculating odds ratios (ORs) with binomial logistic regressions. We also assessed the population-level transmission of strains associated with cavitary disease and treatment failure using terminal branch length analysis of the phylogenetic data. M tuberculosis clinical strains had diverse growth characteristics in host-like metabolic and drug conditions. These fitness phenotypes were highly heritable, and we identified monogenic and phylogenetically linked variants associated with the fitness phenotypes. These data enabled us to define two genetic features that were associated with clinical outcomes. First, mutations in Rv1339, a phosphodiesterase, which were associated with slow growth in glycerol, were further associated with treatment failure (OR 5·34, 95% CI 1·21-23·58, p=0·027). Second, we identified a phenotypically distinct slow-growing subclade of lineage 1 strains (L1.1.1.1) that was associated with cavitary disease (OR 2·49, 1·11-5·59, p=0·027) and treatment failure (OR 4·76, 1·53-14·78, p=0·0069), and which had shorter terminal branch lengths on the phylogenetic tree, suggesting increased transmission. Slow growth under various antibiotic and metabolic conditions served as in-vitro intermediate phenotypes underlying the association between M tuberculosis monogenic and phylogenetically linked mutations and outcomes such as cavitary disease, treatment failure, and transmission potential. These data suggest that M tuberculosis growth regulation is an adaptive advantage for bacterial success in human populations, at least in some circumstances. These data further suggest markers for the underlying bacterial processes that contribute to these clinical outcomes.

Bacterial foodborne infections are a major public health concern globally, and the emergence of antimicrobial-resistant bacteria in food worsens the associated problems which are alarming issues. The current study aimed to isolate E. coli, determine antimicrobial resistance patterns, estimate the prevalence of extended-spectrum beta-lactamase-producing E. coli, and determinants of raw cow milk contamination at selling points in and around Chencha, Southern Ethiopia from January 2021 to April, 2022. A total of 384 milk samples were collected randomly using a cross-sectional study and processed in the laboratory for evaluation of microbial load, bacterial isolation, and antimicrobial susceptibility patterns. The determinants were assessed through a prepared questionnaire, and descriptive statistics and multivariable logistic regression analysis were performed using SPSS version 21. Out of 384 milk samples analyzed for microbial loads, 5.3±1.68 log and 2.17±1.51 log CFU/mL respectively were the mean values of total viable count and total coliform count. A total of 118 (30.7%) samples were contaminated with E. coli of about 11.8% extended-spectrum beta-lactamase producers. Notably, 91 (77.1%) of isolates were multiple drug-resistant isolates. The multivariable logistic regression showed that variables of educational status of milk handlers, hand washing activities, nose picking habit of milk handlers, milk container cleaning activity, milk container type, physical abnormal milk checking status, and attended training on hygienic food handling practices type were significantly associated with the milk contamination in the study area. The results implied that the raw milk samples served in the study area contained bacterial pathogens and a higher microbial load than recommended standards. Our data also confirmed the presence of multiple drug resistant and extended-spectrum beta-lactamase producing E. coli. Therefore, a close follow-up and training of milk handlers is needed. Besides, consumers should be made aware of the risks of consuming raw milk.
Balancing the trade-off between permeability and selectivity while realizing multiple sieving from complex matrices remains as bottlenecks for membrane-based separation. Here, a unique nanolaminate film of transition metal carbide (MXene) nanosheets intercalated by metal-organic framework (MOF) nanoparticles was developed. The intercalation of MOFs modulated the interlayer spacing and created nanochannels between MXene nanosheets, promoting a fast water permeance of 231 L m-2 h-1 bar-1. The nanochannel endowed a 10-fold lengthened diffusion path and the nanoconfinement effect to enhance the collision probability, establishing an adsorption model with a separation performance above 99% to chemicals and nanoparticles. In addition to the remained rejection function of nanosheets, the film integrated dual separation mechanisms of both size exclusion and selective adsorption, enabling a rapid and selective liquid phase separation paradigm that performs simultaneous multiple chemicals and nanoparticles sieving. The unique MXenes-MOF nanolaminate film and multiple sieving concepts are expected to pave a promising way toward highly efficient membranes and additional water treatment applications.
Bangladesh is a developing country where 11% of the population has at least one disability, but no community-level mental health service is available. There is limited evidence of the burden of mental health issues and health-seeking behaviour among this population. This study assessed the feasibility of a training intervention for persons with disabilities, where peer support providers provided community-based disability-inclusive mental health services. Four stakeholder groups participated in this qualitative study: peer responders (trained persons with disabilities), trainers, representatives of organisations of persons with disabilities and disability-specific organisations, and officials of international and national non-governmental organisations. Two types of qualitative interviews were used to collect data, and thematic analysis techniques were utilised. Stakeholders perceived the peer responder training programme as acceptable for persons with disabilities to develop themselves as peer support providers, with potential benefits including increased mental health literacy, ensuring accessible mental health services, and improving the well-being of persons with disabilities. Potential challenges included receiving training and delivering services. Increased training duration, more fieldwork, supervision opportunities, and refresher training were recommended to mitigate training challenges. Financial support and formal community recognition were deemed necessary for training delivery. The peer responder training programme was feasible to ensure accessible mental health services for persons with disabilities, build a workforce to screen for mental health conditions, and provide appropriate referrals. A multi-sectoral collaboration of government and non-governmental institutions is recommended to policy advocates to expand the peer responder training programme in the mainstream mental healthcare system.
Barely one-fifth of people in Sweden have expressed their will regarding organ donation in the national Swedish Donor Registry, and the number of organ donations in Sweden remains low. The aim of this study was to map behaviour and beliefs regarding organ donation in Sweden. In a descriptive cross-sectional survey following a quantitative approach and 600 questionnaires were issued to randomly selected individuals across Sweden. Of them, 206 (36.3%) were completed. Data were analysed using descriptive statistics and presented as frequencies and percentages. Analytical statistical testing involved Pearson chi-square tests, Mann-Whitney U tests, and Kruskal-Wallis tests. The results indicate a discrepancy between positive opinion about organ donation in Sweden and the number of people enrolled in the Swedish Donation Registry. The most common argument for not wanting to donate organs was the notion of being too old to. Although self-rated knowledge about organ donation was admittedly low, so was interest in interest in learning more about it. Younger patients more frequently wanted information than older patients did. Not wanting to donate organs due to age and/or illness may indicate a misconception. Making one's will known does not involve assessing one's health status or age but solely concerns the wish to do so. The findings thus raise an important question: How can people's interest in learning more about organ donation be induced in ethical ways?
Barriers to access to hepatitis C treatment with direct-acting antivirals in people who inject drugs in the community setting. Qualitative study with prison population. Hepatitis C (HCV) treatments with direct-acting antiviral therapy (DAA) are an easy and effective option among people who inject drugs (PWID). However, difficulties in accessing and monitoring treatment in community services and dropouts on release from prison are detected among PWID. For this reason, the aim of the study is to know the access barriers in the diagnosis and treatment of HCV in community health services. An exploratory qualitative study was carried out through semi-structured interviews with 33 PWID recruited in a pre-trial detention prison in Barcelona. The information obtained was analysed using grounded theory. Among PWID sub-population entering prison, personal barriers are related to intense drug use, lack of interest and ignorance of HCV infection and treatment, as well as being in a situation of social exclusion. In relation to health providers, they reported receiving little information, the existence of language barriers in migrants, not receiving screening and treatment proposals, and having poor interactions with some professionals. Systemic barriers were expressed related to the health system circuit being complicated, perceiving little comprehensive care and lack of community support. It is recommended to intensify prevention and treatment campaigns, promoting drug substitution programmes than current ones, improve health education, make the diagnosis and treatment process more flexible, and promote social policies and holistic care for greater coverage of the needs of PWID.
Based on a grounded theoretical analysis of interviews and open data, this study develops a model delineating the factors influencing Knowledge Anxiety, encompassing 5 primary categories and 20 subcategories. These categories encompass Academic Characteristics (knowledge quantity, knowledge quality, and knowledge content), Outer Environment (paid marketing, negative feedback, intense competition, and evaluation mechanism), and Cognitive Environment (work stress, scientific research funding, interpersonal relationships, Time limitation, and Cause difficult) which have been identified as external drivers influencing researchers' Knowledge Anxiety. Conversely, Ability Characteristics (scientific literacy, personality traits, English proficiency, and self-expectations) and Emotional Cognition (inertia thinking, negative self-concept, perceived risks, self-efficacy, and knowledge demand) have been recognized as internal drivers impacting researchers' Knowledge Anxiety. Findings reveal that external factors such as Academic Characteristics, Outer Environment, and Cognitive Environment directly impact researchers' susceptibility to Knowledge Anxiety. Internal factors, represented by Individual Competencies and Emotional Perception, also wield significant influence. Furthermore, external forces can affect Knowledge Anxiety either directly or indirectly by interfacing with internal determinants. This study underscores that researchers' Knowledge Anxiety emerges from intricate interactions among diverse factors, rather than stemming from a solitary cause. These insights furnish valuable comprehension and prospective strategies for mitigating Knowledge Anxiety among researchers, ultimately contributing to the advancement of research in this domain.
Based on summarizing the essential procedures and elements of traditional manipulation techniques of warming needle moxibustion and determining the quantitative parameters and indicators for evaluating the operation of this acupuncture technique, a training instrument of warming needle moxibustion was developed and adopted in the curriculum teaching of practice. It showed that this instrument could quantify the speed of fixing mugwort ball on the needle handle, the number of the prepared mugwort ball, the duration for anti-vibration, the frequency of anti-vibration and the burning time of mugwort ball. The instrument could objectively evaluate the skills of warming needle moxibustion and the effects of fixing mugwort ball. Besides, it may provide the references to improve the protocol of the future research. The development and application of the practical training instrument of warming needle moxibustion is conductive to cultivate the standardization and accuracy of the technique operation in students, and it is significant for objectif-ying the teaching course of warming needle and teaching assessment, as well as for diversifying the teaching modes. Moreover, it plays an exemplary role in the practical training of other acupuncture and moxibustion techniques.
Based on the digital twin technology, a digital twin platform can be built to connect the real teaching space with the virtual teaching space and become the mainstream of online teaching space. All this has determined that the social demand for designers' education is undergoing fundamental changes. The so-called "scientific and technological progress, education first" bilingual education is undergoing comprehensive and profound changes in the digital age, which has a strong impact on the traditional bilingual teaching mode and concept. Traditional concepts, aging theoretical knowledge, and backward teaching methods will inevitably be eliminated and updated gradually in the contest with digitalization, which makes it necessary to transform traditional bilingual education into digital bilingual education. Through the comparative experimental analysis of the teaching effect, the independent sample t-test shows that the t-statistic is 3.634, and the corresponding significance level is 0.013, which is less than 0.05. It shows that there are significant differences between boys and girls in bilingual teaching in this class of digital twin technology experimental teaching. However, compared with the control class, the results of both boys and girls are higher, so to some extent, it shows that the application of digital twin technology experimental teaching in bilingual teaching will indeed produce certain results.
Based on the updated teaching philosophy of oral microbiology, Wuhan University School of Stomatology initiated a reform in the teaching of oral microbiology in 2009. As part of this reform, an oral microbiology laboratory course was introduced to cultivate students' fundamental skills, professional competence, comprehensive abilities, and innovation capabilities through experimental design. This paper provides thorough examination of the teaching experiment findings from 2013 to 2022, a ten-year timeframe, building on earlier data. The curriculum targets fourth-year undergraduate students in a five-year program and adopts a cooperative learning approach. The experimental teaching mainly involves four parts: plaque collection and processing, isolation and cultivation of dental plaque bacteria, staining and biochemical identification of dental plaque bacteria. This article presents a comprehensive analysis of the student experiment results from 2013 to 2022. Statistical analysis was conducted using the chi-square test to assess whether there were any differences in students' experimental grades between different years. A significance level of P < 0.05 was considered statistically significant. Additionally, we evaluated the impact of teaching methods and educational systems on improving students' practical skills and overall innovative abilities. The performance of 664 undergraduate students showed improvement in the oral microbiology laboratory course, with a noticeable decrease in the proportion of "C" grades in Experiments 2, 3, and 4 compared to Experiment 1. These results indicate that the laboratory course enhanced students' academic achievements, aiding their understanding and mastery of course content, and received positive feedback from the students. This lab curriculum, through systematic laboratory teaching and practical experience, contributes to the enhancement of students' professional skills and research abilities. It fosters students' interest in scientific research and improves the quality of dental education.
Basic elementary function is an important module in mathematics learning, and its abstract nature leads to an increase in learning difficulty. Computer information technology has created a new path for visualizing abstract content. Computer-aided teaching is an educational means that has emerged in recent years, but there are many problems that need to be solved urgently in the process of using it. This paper aims to emphasize the importance of computer in mathematics education and compare computer-aided education with other forms of teaching technology. Therefore, based on the constructivist learning theory, this paper puts forward educational strategies to make learning more enjoyable and sustainable through the computer-aided teaching and learning (CATL) system. The proposed method is an important idea to implement and apply each teacher's teaching and learning experience, thus making learning enjoyable and interactive. The CATL system is a gateway to enhance the efficiency and sustainability of the education system. Computer education is part of the curricula of schools because it is vital to every learner today. The research results from 320 students and 8 teachers in a university show that, the CATL system improves the student's performance and interaction between teacher and student. The CATL attains 94.43% of the performance rate, which is not attainable by other approaches.
Basic non-military flight nurse training is essential for enhancing nurses' competency in conducting aeromedical evacuations. Trained nurses possessing flight nurse proficiency are indispensable for ensuring stable patient conditions amidst the unique physical, physiological, and psychological challenges encountered during flights. This study aimed to describe the experiences and perceptions of nurses and air ambulance service providers regarding aeromedical evacuations. This study employed a qualitative descriptive design. Data were gathered from February to July 2023 through semi-structured online interviews with seven nurses and air ambulance service providers engaged in aeromedical evacuation. Content analysis was utilized to interpret the interview data. Seven themes were generated: 1) Experiences in aeromedical evacuation experiences, 2) Challenges faced by nurses and air ambulance service providers during aeromedical evacuations, 3) Essential knowledge for nurses involved in aeromedical evacuations, 4) Efforts to improve nurses' knowledge and skills, 5) Leveling of flight nurse training, 6) Flight nurse training methods, and 7) Flight nurse training evaluation strategies. Nurses and air ambulance service providers acknowledge the significant influence of the flight environment on changes in patient conditions during aeromedical evacuations. To effectively manage alterations in patient conditions during flights, healthcare workers equipped with aviation health competency are imperative. One approach to enhancing the competency of healthcare workers is through flight nurse training. The findings from this study serve as a valuable resource for policymakers and health-related institutions endeavoring to formulate aeromedical evacuation strategies.
Basic quantitative abilities are thought to have an innate basis in humans partly because the ability to discriminate quantities emerges early in child development. If humans and nonhuman primates share this developmentally primitive foundation of quantitative reasoning, then this ability should be present early in development across species and should emerge earlier in monkeys than in humans because monkeys mature faster than humans. We report that monkeys spontaneously make accurate quantity choices by 1 year of age in a task that human children begin to perform only at 2.5 to 3 years of age. Additionally, we report that the quantitative sensitivity of infant monkeys is equal to that of the adult animals in their group and that rates of learning do not differ between infant and adult animals. This novel evidence of precocious quantitative reasoning in infant monkeys suggests that human quantitative reasoning shares its early developing foundation with other primates. The data further suggest that early developing components of primate quantitative reasoning are constrained by maturational factors related to genetic development as opposed to learning experience alone.
