Synergistic effect of silicon availability and salinity on metal adsorption in a common estuarine diatom.

Increasing nitrogen and phosphorus discharge and decreasing sediment input have made silicon (Si) a limiting element for diatoms in estuaries. Disturbances in nutrient structure and salinity fluctuation can greatly affect metal uptake by estuarine diatoms. However, the combined effects of Si and salinity on metal accumulation in these diatoms have not been evaluated. In this study, we aimed to investigate how salinity and Si availability combine to influence the adsorption of metals by a widely distributed diatom Phaeodactylum tricornutum. Our data indicate that replete Si and low salinity in seawater can enhance cadmium and copper adsorption onto the diatom surface. At the single-cell level, surface potential was a dominant factor determining metal adsorption, while surface roughness also contributed to the higher metal loading capacity at lower salinities. Using a combination of non-invasive micro-test technology, atomic force microscopy, X-ray photoelectron spectroscopy, and Fourier transform infrared spectroscopy, we demonstrate that the diversity and abundance of the functional groups embedded in diatom cell walls vary with salinity and Si supply. This results in a change in the cell surface potential and transient metal influx. Our study provides novel mechanisms to explain the highly variable metal adsorption capacity of a model estuarine diatom.

Grupo de mulheres: o desenvolvimento de habilidades de facilitação e a geração de uma dinâmica de grupo promotora de saúde / Women's support group: the development of facilitation skills and the generation of a health-promoting group dynamic / Grupo de mujeres: el desarrollo de habilidades de facilitación y la generación de una dinámica grupal promotora de salud

Introdução: A realização de grupos é uma das possibilidades de atuação das equipes da Atenção Primária à Saúde. Esse tipo de intervenção possibilita o desenvolvimento de ações de cuidado que extrapolam as consultas individuais, propiciando educação em saúde, integração, troca de experiências e ampliação da rede de apoio. Ainda que não tenham necessariamente o propósito de serem terapêuticos em termos de saúde mental, apresentam-se como espaços de promoção de saúde e prevenção de agravos. O trabalho com grupos é capaz de gerar aprimoramento para todas as pessoas envolvidas ­ usuários e profissionais ­ na medida em que possibilita colocar em evidência os saberes da comunidade, abrindo a possibilidade de que as intervenções em saúde sejam criadas em coletivo. Objetivo: Analisar o processo de desenvolvimento da habilidade de facilitação de grupos e os impactos das habilidades adquiridas na sua dinâmica, bem como na sua efetividade como ferramenta de produção de saúde, considerando as habilidades e competências da Medicina de Família e Comunidade. Métodos: Trata-se de pesquisa qualitativa desenvolvida na UBS Santa Cecília. Os encontros aconteceram semanalmente pelo período de uma hora durante seis meses. A ferramenta utilizada para acompanhamento do desenvolvimento da habilidade de facilitação se deu pela observação estruturada, baseada em cinco competências básicas para facilitação de grupos. A dinâmica estabelecida consistiu na determinação de uma profissional facilitadora e outra observadora, que registrou as intervenções realizadas, sendo esses papéis invertidos a cada encontro. Quinzenalmente os dados eram analisados, gerando reflexões e sugestões para melhoria das intervenções. Resultados: Cada competência descrita na ferramenta utilizada teve como resultado o desenvolvimento de habilidades primordiais para o funcionamento do grupo. Um dos maiores indicadores do êxito em alcançar as habilidades desejadas ocorreu pela observação de intervenções cada vez menos necessárias, tomando as participantes os papéis de protagonistas e responsáveis pelo desenvolvimento do grupo, questionando, produzindo e obtendo saúde. Conclusões: A utilização de um instrumento de observação e reflexão das competências do agente atuante como facilitador de um grupo permitiu que a dinâmica se estabelecesse de forma fluida com rápido entendimento das participantes sobre seus papéis no contexto geral do grupo. Observou-se também que a relação estabelecida entre elas resultou na formação de rede de apoio, melhoria do autocuidado e conhecimento, informação em saúde e apoio social às envolvidas.

Introduction: Running support groups is one of the actions of Primary Health Care teams. This type of intervention enables the development of actions that go beyond individual consultations as the only space of care, providing health education, integration, exchange of experiences, and an enlargement in the support network. Although these groups do not necessarily have the purpose of being therapeutic in terms of mental health, they are presented as spaces for building health promotion and disease prevention. The alternative of groups as care practice generates improvement for all involved individuals ­ users and professionals ­ as it makes it possible to highlight the community's knowledge, opening the possibility that health interventions are created collectively. Objective: To analyze the process of ability development in regards to the facilitation of support groups and the impacts of the acquired skills on its dynamics, as well as on its effectiveness as a health production tool, considering the skills and competencies in Family and Community Medicine. Methods: Qualitative study developed at Santa Cecilia BHU. The meetings took place for one hour weekly over a six months period and the tool used to monitor the development of the facilitation skill was the instrument "Structured Observation", based on five basic skills for facilitating groups. The dynamics consisted of the determination of a professional facilitator and an observer, who recorded the interventions that were carried out, with these roles being reversed at each meeting. The data were analyzed bi-weekly, with reflections and suggestions for improving interventions. Results: Each competence described in the tool resulted in the development of essential skills for the functioning of the group. One of the major indicators of the achievement of the desired skills occurred by observing interventions that were less and less necessary, with participants taking on the roles of protagonists and becoming responsible for the development of the group, questioning, producing, and acquiring health. Conclusions: The use of an instrument for observing and reflecting on the skills of the agent acting as a group facilitator allows the dynamics to be fluidly established, with a quick understanding of the participants about their roles in the general context of the group. It was also observed that the relationship established between them resulted in the formation of a support network, improvement of self-care and knowledge, health information and social support for those involved.

Medical faculty's perception of students' mental health: a qualitative survey study / Percepción de los profesores de medicina sobre la salud mental de los estudiantes: un estudio cualitativo / Percepção dos docentes de medicina sobre a saúde mental dos estudantes: um estudo qualitativo

This study sought to explore the perspective of medical faculty on the mental health of their students. This qualitative study based on a focus group is part of a longitudinal research that studied the mental health of Brazilian students. One group was conducted with faculty employed at a medical school. Topics discussed covered the concept of mental health and medical education. Six professors participated in one group. The mental health of medical students is a construct that encompasses emotional aspects, ability to solve problems and multiple facets of a human being, according to the participants. Artistic practices, moments of socialization and leisure were perceived as stimulating students' good mental health. Excessive demands generate competitiveness and the teacher's expectation of the student's good performance based on their own experience can harm the student's mental health. Participants also highlighted that a pedagogical reformulation that makes sense for the student's learning process is necessary to update traditional curricula. Medical students' mental health is influenced by experiences and exchanges during the medical school, mainly between professor and student, understood as necessary and inherent to the process of becoming physician. The findings of this study show the need for curriculum changes in the medical education process and updating teacher training for good practices that reinforce good mental health.

Prevention & management of snakebite envenomation: A qualitative study on perspectives & practices in Maharashtra & Odisha.

Background & objectives Snakebite envenoming (SBE) is a major public health concern, with India bearing the highest global burden of SBE-related deaths. SBE is concentrated in rural and tribal regions of India, where the knowledge, attitude and behaviour of the dwelling communities largely influence mortality and morbidity. Understanding these factors is crucial to designing effective SBE prevention and management strategies. The present study's objective was to document the perspectives of community members and practices in selected blocks of Maharashtra and Odisha States regarding SBE prevention, first aid and health-seeking behaviour. Methods Between March and April 2022, 28 focus group discussions (FGDs) were conducted. Study sites included Shahapur block in Thane district, Aheri block in Gadchiroli district of Maharashtra, and Khordha block in Khordha district, Kasipur block in Rayagada district of Odisha. Separate FGDs were held for males (n=14) and females (n=14), involving about 8-16 participants above 18 yr. All discussions were audio recorded, and a grounded theory approach was employed to identify key themes from the translated transcripts. Results The findings of this study revealed a variety of perspectives and practices determining the SBE burden at the study sites. The findings included insufficient knowledge about snake species and their nature of toxicity, use of non-scientific first aid techniques, inaccessible health care and reliance on traditional healers, non-utilization of prevention methods, varied cultural beliefs and practices, and differential treatments based on gender. The findings have been collated in two simplistic frameworks; barriers to effective prevention and barriers to effective management. Interpretation & conclusions SBE burden results from a complex interplay between socioeconomic, cultural, and demographic factors, necessitating a collaborative inter-sectoral effort for adequate control. Through crucial regional inputs and the barriers to prevention and management models, this study provides critical insights and priority intervention areas to strengthen India's upcoming National Action Plan for Prevention and Control of Snakebite Envenoming (NAPSE) in all high-burden States.

Sickle cell anaemia control mission: Implementation of a comprehensive care model in Anuppur, Madhya Pradesh.

Background & objectives Sickle cell disease (SCD) is a common genetic disorder, predominantly found in the tribal population of India. The examples of models providing comprehensive care and management to individuals with SCD in public health facilities are sparse. The Sickle Cell Anaemia Control Mission is one such model implemented by Jan Swasthya Sahyog, a non-profit organization in collaboration with the National Health Mission in the Anuppur district of Madhya Pradesh. This article aimed to identify the key learnings from this programme that can guide the public health system strengthening with respect to SCD. Methods The Sickle Cell Anemia Control Mission Programme included door to door screening for anaemia, SCD and blood group. SCD cases were included in the programme and other individuals with Anemia were referred for further care. Care for individuals with SCD included counselling, provision of hydroxyurea, regular follow up of clinical parameters and management of complications. Care for individuals with SCD was provided through monthly patient support group (PSG) meetings and regular outpatient /in-patient care at public health facilities. Quantitative data on programme design, screening and patient management collected during programme implementation were used for analysis. Results A total of 39421 persons were screened in 18 months (August 2018-March 2020). Of these 81.9 per cent persons were anaemic, 16.9 per cent had sickle cell trait and 779 (1.98%) had SCD. Eighty-six already diagnosed individuals joined the programme for care. People from all caste categories were diagnosed with SCD. Out of 865 individuals with SCD, 157 underwent regular 9-11 months follow up and showed improvement in clinical symptoms and drug compliance. Interpretation & conclusions Central India has a significant burden of anaemia and SCD. This study found that SCD is present in non-tribals as well. PSGs are an efficient way to deliver non-emergency care for chronic diseases such as SCD.

'It opens up a whole new world for everybody': how carers of people with dementia view the online empowered conversations communication course.

OBJECTIVES: This paper explores (1) experiences of participating in Empowered Conversations, an online communication course for carers of people with dementia and (2) how participants felt the course had changed their experience of caring. METHOD: Fifteen semi-structured interviews were completed with carers who had attended Empowered Conversations as part of a larger feasibility trial conducted in Greater Manchester, UK (ISRCTN15261686). Data were analysed using applied thematic analysis. RESULTS: Three themes were developed: (1) You've got nothing to lose and everything to gain, including the course content, timing and format, and perceived burden and benefits of the course; (2). A community to share together, including the value of being honest, vulnerable, and sharing stories; and (3) Being given a new way to see the world, including understanding the person and their diagnosis, enabling greater control and reducing interpersonal conflict, and recalibrating their expectations. CONCLUSION: Carers reported positive experiences of participating in Empowered Conversations and valued meeting people who, despite different circumstances, shared their understanding of supporting someone with dementia. The course supported participants to be honest and vulnerable, and helped them to rethink communication and have a greater appreciation of the other person's perspective during everyday interactions.

Replication and extension of the subregion selectivity of glutamate-related changes within the nucleus accumbens associated with the incubation of cocaine-craving.

Cue-elicited drug-seeking behavior intensifies with the passage of time during withdrawal from drug taking and this "incubation of cocaine-craving" involves alterations in nucleus accumbens (NA) glutamate transmission. Here, we employed a combination of in vivo microdialysis and immunoblotting approaches to further examine changes in biochemical indices of glutamate transmission within NA subregions that accompany the incubation of cocaine-craving exhibited by male rats with a 10-day history of 6-h access to intravenous cocaine (0.25 mg/infusion). Immunoblotting on whole cell lysates from the core subregion (NAc core) revealed interactions between cocaine self-administration history, withdrawal and drug cue re-exposure for Homer2a/b, mGlu1, and GluN2b expression, as well as indices of Akt and ERK activity. With the exception of PKCε phosphorylation, most protein changes within the shell subregion (NAc shell) depended on drug cue re-exposure and cocaine history rather than varying in a consistent time-dependent manner. Reduced basal extracellular glutamate content was apparent only in the NAc core of cocaine-experienced rats during protracted (30 days) withdrawal and this was accompanied by a markedly blunted capacity of the mGlu1/5 agonist DHPG to elevate glutamate levels within this subregion. Finally, over-expressing neither Homer1c nor Homer2b within the NAc core during protracted cocaine withdrawal altered the magnitude of cue-elicited responding, its extinction or cocaine-primed reinstatement of drug-seeking behavior. The present findings are consistent with the extant literature implicating changes in Group 1 mGlu receptor function within the NAc core subregion as central to incubated cocaine-craving and provide further evidence against a major role for Homer proteins in gating incubated cocaine-craving. Further, our results provide novel correlational evidence implicating elevated Akt and blunted ERK activity within the NAc core as potential contributors to the expression of incubated cocaine-craving, worthy of future investigation.

Wutou Decoction attenuates rheumatoid arthritis in rats through SIRT1-mediated deacetylation of the HMGB1/NF-κB pathway.

ETHNOPHARMACOLOGICAL RELEVANCE: In traditional Chinese medicine (TCM), Wutou Decoction (WTD) has long been used to alleviate arthritis. Emerging studies have reported that WTD could improve the symptoms of rheumatoid arthritis (RA). However, the mechanism by which WTD is involved in the treatment of RA remains elusive, posing a challenge to the worldwide acceptance of WTD as an efficient RA therapy. AIM OF THE STUDY: This study investigated the antiarthritic efficacy of WTD in a collagen-induced arthritis (CIA) rat model and explored silent information regulator 1 (SIRT1)-mediated deacetylation of the high mobility group box 1 (HMGB1)/NF-κB pathway. MATERIALS AND METHODS: A rat CIA model was used to evaluate the antiarthritic activity of WTD. Clinical arthritis score assessment, left ankle thickness assessment, micro-CT, histopathological staining, immunofluorescence staining, and ELISA were conducted to elucidate the anti-inflammatory effects of WTD. The M1 macrophage polarization state, cell viability, and invasion were also determined to assess the effects of WTD on macrophage proliferation and invasion in vitro. Additionally, in vivo and in vitro HMGB1 nuclear translocation and NF-κB activation were analysed. Finally, deacetylase activity was assessed by Western blot, NAD+/NADH analysis, and co-immunoprecipitaion. RESULTS: WTD significantly alleviated arthritis in CIA rats and inhibited pathological changes in joint lesions while concurrently suppressing TNF-α, IL-6, and IL-1ß release. Mechanistically, WTD suppressed M1 infiltration in ankle tissues and their invasion in vitro. Furthermore, WTD downregulated HMGB1/p65 nuclear translocation and acetylation, which may be associated with SIRT1 upregulation. CONCLUSIONS: Overall, WTD potentially alleviates RA through SIRT1-mediated downregulation of HMGB1 and NF-κB acetylation.

A systematic scoping review on group non-written reflections in medical education.

BACKGROUND: Medical education is tasked with shaping how medical students and physicians think, feel and act as professionals, or their Professional Identity Formation (PIF). This process has traditionally rested upon imparting knowledge; integrating sociocultural, professional and organizational expectations and codes of conduct; inculcating program and practice beliefs, values and principles (belief systems); and imbuing shared identities - quintessential elements that, together, comprise the socialization process. Key to supporting this socialization process is reflective practice. However, regnant approaches to mobilizing reflective cycles are faced with resource, personnel and time constraints, hindering efforts to nurture PIF. Group non-written reflections (GNWR) - broadly defined as facilitator-led discussions of shared reflective experiences within groups of learners - may prove to be an effective compromise. To address diverse approaches and a lack of effective understanding, we propose a systematic scoping review (SSR) to map the current use of GNWR in medical training and its role in shaping PIF. METHODS: Guided by the Systematic Evidence-Based Approach (SEBA)'s constructivist ontological and relativist epistemological position, this SSR in SEBA searched for articles on GNWR published in PubMed, Embase, Psychinfo, CINAHL, ERIC, ASSIA, SCOPUS, Google Scholar, Open Grey, GreyLit and ProQuest databases. The data found was concurrently analyzed using thematic and direct content analysis. Complementary themes and categories identified were combined, creating the domains that framed the discussion. RESULTS: Of the 8560 abstracts and 336 full-text articles reviewed, 98 articles were included. The four domains identified were: (1) Indications of use and their value; (2) Structure and how they can be used; (3) Models of reflective practice in GNWR; and (4) Features of communities of practice and the socialisation process. CONCLUSION: This SSR in SEBA concludes that GNWR does impact PIF when effectively structured and supported. The Krishna-Pisupati Model for PIF platforms a model that explains GNWR's effects of PIF and advances fourteen recommendations to maximize GNWR use.

How do pig veterinarians view technology-assisted data utilisation for pig health and welfare management? A qualitative study in Spain, the Netherlands, and Ireland.

BACKGROUND: Application of data-driven strategies may support veterinarians' decision-making, benefitting pig disease prevention and control. However, little is known about veterinarians' need for data utilisation to support their decision-making process. The current study used qualitative methods, specifically focus group discussions, to explore veterinarians' views on data utilisation and their need for data tools in relation to pig health and welfare management in Spain, the Netherlands, and Ireland. RESULTS: Generally, veterinarians pointed out the potential benefits of using technology for pig health and welfare management, but data is not yet structurally available to support their decision-making. Veterinarians pointed out the challenge of collecting, recording, and accessing data in a consistent and timely manner. Besides, the reliability, standardisation, and the context of data were identified as important factors affecting the efficiency and effectiveness of data utilisation by veterinarians. A user-friendly, adaptable, and integrated data tool was regarded as potentially helpful for veterinarians' daily work and supporting their decision-making. Specifically, veterinarians, particularly independent veterinary practitioners, noted a need for easy access to pig information. Veterinarians such as those working for integrated companies, corporate veterinarians, and independent veterinary practitioners expressed their need for data tools that provide useful information to monitor pig health and welfare in real-time, to visualise the prevalence of endemic disease based on a shared report between farmers, veterinarians, and other professional parties, to support decision-making, and to receive early warnings for disease prevention and control. CONCLUSIONS: It is concluded that the management of pig health and welfare may benefit from data utilisation if the quality of data can be assured, the data tools can meet veterinarians' needs for decision-making, and the collaboration of sharing data and using data between farmers, veterinarians, and other professional parties can be enhanced. Nevertheless, several notable technical and institutional barriers still exist, which need to be overcome.

Evaluation of a Novel Independent Group Contingency in an Alternative School.

We evaluated a novel group contingency arrangement designed to address implementation barriers commonly cited by teachers in alternative education. Barriers include implementer effort, disruption caused by delivering feedback to students, students sabotaging the game, and students maximizing disruption when they know the reinforcement criterion. To address these barriers, we decreased implementer effort using the principles of time sampling, omitted feedback for rule violations, arranged an independent group contingency to address sabotage, and did not disclose reinforcement criteria to students. The intervention produced marked reductions in disruption across four alternative middle- and high-school classes.

William Coley: The Pioneer and the Father of Immunotherapy.

William Coley was an unacclaimed hero of early cancer treatment. His work is often overshadowed by more recent advancements in immunotherapy. Coley's innovative work in the 1910s and 1930s laid the groundwork for what would become a major field in oncology. His experiments with bacterial vaccines by making use of the immune system to combat cancer preceded contemporary immunotherapy for several decades. This review provides a comprehensive exploration of Coley's life, his groundbreaking research, the socio-scientific challenges he faced, and his lasting impact on cancer treatment. Even though he faced lots of initial resistance and challenges, Coley's work has influenced modern immunotherapy practices.

Consensus on innovations and future directions of community first responder schemes in United Kingdom: a national nominal group technique study.

AIM: We aimed to achieve consensus among NHS and community stakeholders to identify and prioritise innovations in Community First Responder (CFR) schemes. METHODS: We conducted a mixed-methods study, adopting a modified nominal group technique with participants from ambulance services, CFR schemes and community stakeholders. The 1-day consensus workshop consisted of four sessions: introduction of innovations derived from primary research; round-robin discussions to generate new ideas; discussion and ranking of innovations; feedback of ranking, re-ranking and concluding statements. Innovations were ranked on a 5-point Likert scale and descriptive statistics of median and interquartile range calculated. Discussions were recorded, transcribed, and analysed thematically. RESULTS: The innovations found were classified into two categories: process innovations and technological innovations. The process innovations included six types of innovations: roles, governance, training, policies and protocols, recruitment, and awareness. The technological innovations included three aspects: information and communication; transport; and health technology. The descriptive statistics revealed that innovations such as counselling and support for CFRs (median: 5 IQR 5,5), peer support [5 (4,5)], and enhanced communication with control room [5 (4,5)] were essential priorities. Contrastingly, innovations such as the provision of dual CFR crew [1.5 (1,3)], CFR responsibilities in patient transport to hospital [1 (1,2)], and CFR access to emergency blue light [1 (1,1.5)] were deemed non-priorities. CONCLUSIONS: This article established consensus on innovations in the CFR schemes and their ranking for improving the provision of care delivered by CFRs in communities. The consensus-building process also informed policy- and decision-makers on the potential future change agenda for CFR schemes.

Stakeholder Consultation to Establish Research Priorities for Specialist Dementia Nursing in the United Kingdom.

INTRODUCTION: In the United Kingdom, there are a growing number of specialist dementia nurses called Admiral Nurses. Admiral Nurses, supported in their professional development and clinical supervision by the charity Dementia UK, work with families affected by dementia using a relationship-centred approach. Given the growing need for this type of support, Dementia UK is committed to research that will expand the evidence base for Admiral Nursing. This article describes a stakeholder consultation to identify research priorities for Admiral Nursing for the next 3 years (2023-2026). METHODS: We adopted a participatory approach using an adapted Nominal Group Technique and priority-setting workshop. All elements of the process were designed in consultation with a steering group comprising a range of stakeholders, including people with dementia, carers, Admiral Nurses, Dementia UK staff and researchers. Stakeholders were identified as those who were likely to be affected by or interested in the emerging research priorities. Nominal groups were held both face-to-face and online. A total of 144 people shared their research priorities. Data generated through each nominal group were thematically analysed and then ranked in order of priority. RESULTS: Four themes reflecting research priority areas were taken to a priority-setting workshop for consideration. This resulted in three research priorities for Admiral Nursing: (1) people with dementia who live alone and carers who provide support from a distance; (2) people living with young onset and rarer dementia and their families; and (3) people living with multiple health conditions alongside dementia, including mental health problems. Risk, diversity and the effectiveness of Admiral Nursing were strands that ran throughout these themes. CONCLUSIONS: We identified shared research priorities for Admiral Nursing using a rigorous, consensus-driven approach involving key stakeholders. These priorities reflect a desire to ensure that Admiral Nursing services reach the most vulnerable people living with dementia and their families and respond to the widening health and social care inequalities faced by this group. PATIENT AND PUBLIC CONTRIBUTION: People with dementia and carers were involved in the design of this process as members of our steering group and through consultation on our initial plans with Dementia UK's Lived Experience Advisory Panel (LEAP). People living with dementia and carers also participated in consultation groups to share their views on research priorities. All stakeholders were invited to share feedback on the themes as part of the analysis and interpretation of the priorities, and a meeting was held with LEAP to discuss the emerging priorities.

Identifying group metacognition associated with medical students' teamwork satisfaction in an online small group tutorial context.

BACKGROUND: Collaborative learning is an essential pedagogy in medical education, within which small group learning constitutes an integral component. Online small group teaching has been widely applied and blended with in-person sessions in the aftermath of the Covid-19 pandemic. This study examined whether group metacognition was associated with teamwork satisfaction in an online small group teaching curriculum for medical students. METHODS: We enrolled medical students of the 2nd and 4th years during the 2021 fall semester after they participated in 3 consecutive sessions of online small group tutorials (SGTs), which have been implemented in our medical school for more than 20 years. The students completed a group metacognitive scale (GMS) and a teamwork satisfaction scale (TSS) after the sessions. We analyzed whether group metacognition in 4 dimensions (knowledge of cognition, planning, evaluating, and monitoring) could be connected with medical students' teamwork satisfaction using partial least squares-structural equation modeling (PLS-SEM). RESULTS: A total of 263 medical students participated in this study. Both GMS and TSS exhibited good reliability and validity. Three of the 4 dimensions of group metacognition (cognition, planning, and evaluating) positively correlated with teamwork satisfaction (path coefficients 0.311, 0.279, and 0.21; p = 0.002, 0.002, and 0.043, respectively) following the online SGT curriculum, whereas the monitoring dimension did not (path coefficient 0.087; p = 0.357). The model achieved an adjusted R square of 0.683. CONCLUSION: We discovered that group metacognition correlated positively with better teamwork satisfaction, supporting the importance of group metacognitive competency for online collaborative learning.

Multicategory Survival Outcomes Classification via Overlapping Group Screening Process Based on Multinomial Logistic Regression Model With Application to TCGA Transcriptomic Data.

Objectives: Under the classification of multicategory survival outcomes of cancer patients, it is crucial to identify biomarkers that affect specific outcome categories. The classification of multicategory survival outcomes from transcriptomic data has been thoroughly investigated in computational biology. Nevertheless, several challenges must be addressed, including the ultra-high-dimensional feature space, feature contamination, and data imbalance, all of which contribute to the instability of the diagnostic model. Furthermore, although most methods achieve accurate predicted performance for binary classification with high-dimensional transcriptomic data, their extension to multi-class classification is not straightforward. Methods: We employ the One-versus-One strategy to transform multi-class classification into multiple binary classification, and utilize the overlapping group screening procedure with binary logistic regression to include pathway information for identifying important genes and gene-gene interactions for multicategory survival outcomes. Results: A series of simulation studies are conducted to compare the classification accuracy of our proposed approach with some existing machine learning methods. In practical data applications, we utilize the random oversampling procedure to tackle class imbalance issues. We then apply the proposed method to analyze transcriptomic data from various cancers in The Cancer Genome Atlas, such as kidney renal papillary cell carcinoma, lung adenocarcinoma, and head and neck squamous cell carcinoma. Our aim is to establish an accurate microarray-based multicategory cancer diagnosis model. The numerical results illustrate that the new proposal effectively enhances cancer diagnosis compared to approaches that neglect pathway information. Conclusions: We showcase the effectiveness of the proposed method in terms of class prediction accuracy through evaluations on simulated synthetic datasets as well as real dataset applications. We also identified the cancer-related gene-gene interaction biomarkers and reported the corresponding network structure. According to the identified major genes and gene-gene interactions, we can predict for each patient the probabilities that he/she belongs to each of the survival outcome classes.

Case Report: MDFIC gene mutation resulting in central conducting lymphatic anomaly facilitates group A Streptococcus sepsis.

Background: Central conducting lymphatic anomaly (CCLA) is a heterogeneous disorder characterized by structural anomalies in the main collecting lymphatic vasculature. These anomalies result in chronic chylous leaks, causing issues such as congenital hydrothorax and potentially impairing the normal immune response. Recently, mutations in the MyoD family inhibitor domain-containing (MDFIC) gene have been identified as a cause of CCLA. Group A Streptococcus infections are common, and timely identification of patients at risk for severe complications is crucial. Case presentation: Here, we present the case of a 13-year-old female patient with CCLA associated with an MDFIC mutation, who suffered from a severe group A Streptococcus sepsis. Initially, the patient was unresponsive to aggressive fluid resuscitation. Although the course of the sepsis was severe, standardized treatment according to the surviving sepsis campaign proved effective in stabilizing the patient. Discussion: The patient's MDFIC mutation may have contributed to the severe clinical course of the sepsis. It is theorized that this mutation affects the function of the immune system both indirectly, by causing CCLA, and directly, by potentially influencing transcriptional activity in immune cells. More research on the effect of MDFIC mutations on immune responses is required.

Phylogenetic evidence of extensive spatial mixing of diverse HIV-1 group M lineages within Cameroon but not between its neighbours.

From the perspective of developing relevant interventions for treating HIV and controlling its spread, it is particularly important to comprehensively understand the underlying diversity of the virus, especially in countries where the virus has been present and evolving since the cross-species transmission event that triggered the global pandemic. Here, we generate and phylogenetically analyse sequences derived from the gag-protease (2010 bp; n = 115), partial integrase (345 bp; n = 36), and nef (719 bp; n = 321) genes of HIV-1 group M (HIV-1M) isolates sampled between 2000 and 2022 from two cosmopolitan cities and 40 remote villages of Cameroon. While 52.4% of all sequenced viruses belonged to circulating recombinant form (CRF) 02_AG (CRF02_AG), the remainder were highly diverse, collectively representing seven subtypes and sub-subtypes, eight CRFs, and 36 highly divergent lineages that fall outside the established HIV-1M classification. Additionally, in 77 samples for which at least two genes were typed, 31% of the studied viruses apparently had fragments from viruses belonging to different clades. Furthermore, we found that the distribution of HIV-1M populations is similar between different regions of Cameroon. In contrast, HIV-1M demographics in Cameroon differ significantly from those in its neighbouring countries in the Congo Basin (CB). In phylogenetic trees, viral sequences cluster according to the countries where they were sampled, suggesting that while there are minimal geographical or social barriers to viral dissemination throughout Cameroon, there is strongly impeded dispersal of HIV-1M lineages between Cameroon and other locations of the CB. This suggests that the apparent stability of highly diverse Cameroonian HIV-1M populations may be attributable to the extensive mixing of human populations within the country and the concomitant trans-national movements of major lineages with very similar degrees of fitness; coupled with the relatively infrequent inter-national transmission of these lineages from neighbouring countries in the CB.

Group acceptance sampling plan based on truncated life tests for Type-I heavy-tailed Rayleigh distribution.

This study on the Type-I heavy-tailed Rayleigh (TI-HTR) distribution is a special case of Type-I heavy-tailed (TI-HT) family of distributions was studied. The characteristics were derived, including the moment and its measures, quantile function, reliability measures, and other statistical properties as well as parameter estimation using the maximum likelihood method and penalized likelihood estimation. The behavior of its various functions were shown graphically. Analytically, we showed that model linearly grows near the origin and exhibits rapid exponential decay. However, the tail behavior cannot equal the traditional heavy-tail in the power law sense, hence it is called the type-I heavy-tail. Interestingly, we designed a group acceptance plan (GASP) and demonstrated usefulness with both assumed and maximum likelihood estimates. The GASP under the TI-HTR distribution is preferable when the parameter values are small. The distribution was used to model real-life data sets to justify its usefulness. The results of the application of the model to both COVID-19 and Cancer data showed that the model fits the two data better than the competing models and also suggest that inference from the model is better than those of the competitors. In estimating the parameters, the penalized likelihood procedure perform considerably better with minimum standard error of the estimates. From the Cramér-von Mises test results which guides against the heavy-tail sensitivity, the TI-HTR distribution offers a better model for fitting fast decaying exponential data since it has the least statistics in both datasets.
