Authors: Ehrenzeller Selina , Züger Karin , Oberli Lisa , Buonomano Roberto 
Published: February 2025

Bacillus cereus, a gram-positive, rod-shaped bacterium known for both its environmental resilience and its pathogenic potential, has been increasingly recognised as a serious health threat outside the traditional contexts of food poisoning. This narrative review, anchored by a detailed case study, highlights the pathogen’s role in rare but severe infections like endocarditis, especially among intravenous drug users, who are particularly vulnerable, among other identified risk factors. The case of a 62-year-old female with a history of intravenous cocaine use who developed Bacillus cereus endocarditis underscores the complexities of diagnosing and managing such infections. Despite the challenges posed by the patient’s adverse reactions to vancomycin, the mainstay treatment, successful management was achieved through persistent administration adjusted for tolerance and side effects.
This review meticulously compiles all known cases of Bacillus cereus endocarditis from the past decades, beginning with the first identified case fifty years ago in 1974. It provides a thorough analysis, identifying various risk factors and outlining the evolution of treatment protocols. This comprehensive approach not only enhances understanding of the pathogen’s clinical impact but also clarifies the progression of therapeutic strategies, highlighting the individual adaptations necessary to address this challenging infection effectively.

This study examined teachers’ creativity, innovation and emotional intelligence as predictors of transformational education in universities in South-East, Nigeria. Three specific purposes; three research questions, and three hypotheses guided the study. Correlational research design was adopted for the study. The population of the study comprised all the 4,240 teaching staff (2,778 in Nnamdi Azikiwe University, Awka; UNIZIK and 1,462 in Alex Ekwueme Federal University, Ndufu-Alike, Ikwo; AE-FUNAI). The sample size for the study was 424 teaching staff drawn through proportionate stratified random sampling technique. Structured instruments “Creativity Rating Scale (TCRS) developed by the researchers; Innovation Adoption and Impact Questionnaire (IAIQ) developed by Emily Carter in 2021; Emotional Intelligence Rating Scale (EIRS) developed by Schutte et al. in 1998; and Transformational Education Rating Scale (TERS) developed by the researchers” were used for data collection. The instruments were face validated by three experts in Faculty of Education; two lecturers in Educational Management and Policy and one lecturer in Measurement and Evaluation Unit, Department of Educational Foundations Nnamdi Azikiwe University, Awka. Internal consistencies co-efficient of 0.84, 0.90, 0.81, and 0.91 were obtained for TCRS, IAIQ, EIRS, and TERS respectively using Cronbach Alpha statistical method. The researchers administered the instrument to the respondents with the help of six research assistants. Out of the 424 copies of the instruments administered, 409 copies (96.46%) were retrieved duly completed, and used for data analysis. Simple linear regression statistics (R) was used for data analysis. The (R) was used to determine the predictive value of the independent variables and the dependent variable of the study. The p-value was used to determine the significance of the prediction for all hypotheses at 0.05 level of significance. All analyses were carried out using Statistical Package for Social Science (SPSS) Version 25. The study findings revealed that teachers' creativity, innovation, and emotional intelligence are very strong predictors and significantly predict transformational education in universities in South-East Nigeria. Based on the empirical findings, it was concluded that teachers' creativity, innovation, and emotional intelligence are critical components that significantly enhance the effectiveness of transformational education in universities in South-East Nigeria. Based on the findings, the study recommended among others that policymakers should formulate and implement policies that encourage and support teachers' creativity and innovation. This includes funding for research and development in education, as well as policies that integrate emotional intelligence training into teacher preparation programmes.

ImportanceThe consequences of low levels of environmental lead exposure, as found commonly in US household water, have not been established.ObjectiveTo examine whether commonly encountered levels of lead in household water are associated with hematologic toxicity among individuals with advanced kidney disease, a group known to have disproportionate susceptibility to environmental toxicants.Design, Setting, and ParticipantsCross-sectional analysis of household water lead concentrations and hematologic outcomes was performed among patients beginning dialysis at a Fresenius Medical Care outpatient facility between January 1, 2017, and December 20, 2021. Data analysis was performed from April 1 to August 15, 2023.ExposureConcentrations of lead in household water were examined in categorical proportions of the Environmental Protection Agency’s allowable threshold (15 μg/L) and continuously.Main Outcomes and MeasuresHematologic toxic effects were defined by monthly erythropoiesis-stimulating agent (ESA) dosing during the first 90 days of incident kidney failure care and examined as 3 primary outcomes: a proportion receiving maximum or higher dosing, continuously, and by a resistance index that normalized to body weight and hemoglobin concentrations. Secondarily, hemoglobin concentrations for patients with data prior to kidney failure onset were examined, overall and among those with concurrent iron deficiency, thought to increase gastrointestinal absorption of ingested lead.ResultsAmong 6404 patients with incident kidney failure (male, 4182 [65%]; mean [SD] age, 57 [14] years) followed up for the first 90 days of dialysis therapy, 12% (n = 742) had measurable lead in household drinking water. A higher category of household lead contamination was associated with 15% (odds ratio [OR], 1.15 [95% CI, 1.04-1.27]) higher risk of maximum monthly ESA dosing, 4.5 (95% CI, 0.8-8.2) μg higher monthly ESA dose, and a 0.48% (95% CI, 0.002%-0.96%) higher monthly resistance index. Among patients with pre–kidney failure hemoglobin measures (n = 2648), a higher household lead categorization was associated with a 0.12 (95% CI, −0.23 to −0.002) g/dL lower hemoglobin concentration, particularly among those with concurrent iron deficiency (multiplicative interaction, P = .07), among whom hemoglobin concentrations were 0.25 (95% CI, −0.47 to −0.04) g/dL lower.ConclusionThe findings of this study suggest that levels of lead found commonly in US drinking water may be associated with lead poisoning among susceptible individuals.
Orbital Hybridization Induced Dipole Polarization and Room Temperature Magnetism of Atomic Co‐N4‐C toward Electromagnetic Energy Attenuation

Published: May 2024

AbstractManipulating the electronic structure and geometric coordination environment of single metal atoms has been considered as promising approach for enhancing dipole polarization and enriching electromagnetic attenuation mechanisms. However, achieving precise control of the dielectric polarization response at atomic scale remains a huge challenge. Herein, a metal‐acetate coordination complexes‐assisted strategy is proposed to prepare spatially isolated cobalt (Co) atoms embedded in accordion‐like nitrogen‐doped carbon (NC) matrix. The interactions between metal atoms and NC matrix are carefully tailored through the successive evolution of dispersion states of Co species, ranging from individual atoms to atomic clusters to nanoparticles. Density functional theory reveals that the orbital hybridization between the d electrons of embedded Co atoms and p electrons of coordinated N atoms induces the electron redistribution at N sites, enabling enhanced electric dipole polarization and robust room temperature magnetism (a saturation magnetization of 0.108 emu g−1 at 300 K). Consequently, Co‐SAs@NC exhibits optimal electromagnetic wave absorption properties with a minimum reflection loss of ‐54.4 dB and an effective absorption bandwidth of 8.4 GHz. This work demonstrates an efficient strategy for modulating electromagnetic response at atomic level and provides a novel insight into the d/p electrons orbital hybridization between single metal atoms and NC species.

AbstractExcessive inflammation poses a major challenge to wound care, with massive exudation and bacterial infection being the prominent factors contributing to the inflammation. Current biomaterials can achieve passive or interactive wound repair through exudate absorption and anti‐infection. However, they cannot actively modulate the cellular behavior associated with skin wound repair. Inspired by the endogenous electric field (EF), the present study develops an antimicrobial and self‐powered electrical fabric dressing (EFD). An EFD with multifunctional properties of wound exudate collection, anti‐infection, and self‐powered electrical stimulation (ES) is assembled via weaving a series of hydrophilically modified cotton yarn‐based batteries. Upon contact with the wound, EFD absorbs the wound exudate owing to its high hydrophilicity and utilizes it as the natural electrolyte to activate the battery. With the endogenous power supply, the ES‐promoted polarization of macrophage, as well as the migration and proliferation of fibroblasts, enhancing the active wound repair process. Moreover, the dressings exhibit excellent antibacterial properties, attributable to the synergistic effects of the cationic polymer brushes on the cotton yarn and the anodic by‐product (magnesium hydroxide) during discharging. Thus, the wound exudate‐activated EFD can effectively manage wound exudates, prevent bacterial infection, and provide self‐powered electrotherapy to facilitate active wound tissue repair.

AbstractThe revolution of millimeter‐wave (mmWave) technologies is prompting a need for absorption‐dominant EMI shielding materials. While conventional shielding materials struggle in the mmWave spectrum due to their reflective nature, this study introduces a novel EMI shielding film with ultralow reflection (<0.05 dB or 1.5%), ultrahigh absorption (>70 dB or 98.5%), and superior shielding (>70 dB or 99.99999%) across triple mmWave frequency bands with a thickness of 400 µm. By integrating a magnetic composite layer (MCL), a conductive patterned grid (CPG), and a double‐walled carbon nanotube film (DWCNTF), specific resonant frequencies of electromagnetic waves are transmitted into the film with minimized reflection, and trapped and dissipated between the CPG and the DWCNTF. The design factors for resonant frequencies, such as the CPG geometry and the MCL refractive index, are systematically investigated based on electromagnetic wave propagation theories. This innovative approach presents a promising solution for effective mmWave EMI shielding materials, with implications for mobile communication, radar systems, and wireless gigabit communication.

Published: May 2024

AbstractBackgroundFree open‐access medical education (FOAM) is extremely popular among learners and educators despite lacking the traditional peer review process. Despite the potential for inaccurate, low‐quality, or biased content, little has been published describing FOAM authors.MethodsWe performed a cross‐sectional analysis of 12 months of content from the top 25 blogs in the 2020 Social Media Index from August 2020–2021. We recorded the number of posts per site and descriptive characteristics of authors, including gender affiliation, conflicts of interest (COI) statements, and type of practice (academic, community, or hybrid).ResultsWe identified 2141 posts by 1001 authors. More than half were produced by six websites: EM Docs (266), Life in the Fast Lane (232), EMCrit (188), ALiEM (185), Don't Forget the Bubbles (181), and Rebel EM (174). Most content (1680 posts, 78.5%) lacked a COI statement. Authors were mostly academic (89%), mostly held MD degrees (67.4%), and were mostly men (59.7%). Geographically, most FOAM authors reside in the United States (59.5%), Canada (22.42%), or the United Kingdom (9.4%).ConclusionsOf all the posts in the top 25 sites in 2020, more than half came from six sites, and authors were largely North American men in academics with MD degrees. Learners, content creators, and educators should consider the ways in which a more diverse authorship pool might bring value to the FOAM educational experience.
A personal reflection on Bowen family systems theory by Dr Michael Kerr
Authors: Kerr Michael , MacKay Linda 
Published: May 2024

AbstractThis interview with Dr Michael Kerr highlights his ongoing interest in science, biology and neuroscience. Guided by Bowen family systems theory, Dr Kerr's observations examine how research is showing links between physical health, the immune response and psychological motivation and wellbeing. Wellbeing is compromised in less adaptive families, which succumb more easily to any anxiety generated outside the family, as well as the chronic anxiety generated within the family. Amid times of societal regression, the capacity to adapt in a way that promotes survival and wellbeing depends on the level of differentiation of self. Differentiation of self is the sum of the capacity to maintain emotional objectivity, emotional neutrality and to take action. Psychiatrist, Dr Michael (Mike) Kerr, who more recently published Bowen Theory's Secrets: Revealing the hidden lives of families (2019), co‐authored the seminal work on Bowen family systems theory, Family Evaluation, in 1988 with Dr Murray Bowen. From 1990 to 2011, after Dr Bowen's death, Mike was the Director of the Bowen Center for the Study of the Family in Washington, DC. He is passionate about the relationship between differentiation of self, illness and the family emotional process and how this relates to the biological and evolutionary processes that operate in non‐human species. Mike developed the unidisease concept and is well known for his work interviewing Dr Murray Bowen on Bowen family systems theory between 1979 and 1986 for the Bowen‐Kerr Interview Series. A special issue on Bowen theory would not be complete without a commentary from Mike. So, in this interview with Bowen family systems therapist, Dr Linda MacKay, Mike discusses his life effort to research and apply Bowen theory.
Moving around the system: a way of working clinically using Bowen family systems theory
Authors: White Katherine L. 
Published: May 2024

AbstractDr Murray Bowen, developer of Bowen family systems theory (BFST), had this to say to clients about working in family systems: if you get bogged down in one area, move into another (Bowen & Kerr, 1985). This statement, along with the knowledge of BFST, offered an inspiration for thinking about a method of therapy. This article highlights a method of working with an individual through a systemic lens. Two ideas are integral to this focus. One is that a client can move more easily into observing self within the system when they are not just observing self in one context or relationship but rather looking at how they function in different contexts or relationships. And second, by moving into different contexts of the system, the therapist is better able to manage the tendency towards symptom focus and stay centred on the work of differentiation. A therapist can truly have a stadium view of the system when speaking with the client about how they function in different areas of life. This method defined happens in three phases: in phase 1, the client observes themselves in their system in different contexts and looks for patterns in their functioning; in phase 2, the client takes this new self‐recognition and experiments with different ways of being in one context; and in phase 3, the insights gained from experiments in one context are applied in other contexts. Both client and clinician will benefit from less symptom focus and increased ability to observe patterns in relationships, both of which are core tenets of the work of differentiation in BFST.
Investigating the effect of refining parameters on acetic acid removal and the quality of crude epoxidized soybean oil

Published: May 2024

AbstractWashing crude epoxidized oil is an indispensable step for the removal of residual acetic acid and unreacted hydrogen peroxide after epoxidation. There are many studies on the epoxidation of vegetable oils but there are many discrepancies in the washing process which likely leads to water wastage, excess use of neutralizing agent, and additional processing time. Hence, this study aims to optimize the washing step by analyzing the quality of each washing step and developing a model that can predict the amount of acid removed. Soybean oil (1.5 kg) was epoxidized at 60°C for 5.5 h using Amberlite IR 120H as a heterogeneous catalyst. To determine the optimum water washing level, process parameters such as number of washing cycles (1–5), proportion of epoxidized oil to water volume (1:0.5, 1:1, 1:2, 1:3, 1:4, 1:5), and water temperature (20, 40, and 60°C) were examined. The main responses were the residual acid value and pH of the washed epoxidized oil. Results revealed that 64% of the acid was removed after 5 washing cycles irrespective of the washing water temperature and proportion. In contrast, approximately 57% of the acid was removed in the first two washing cycles. Increasing the temperature of the water affected acid removal; with approximately 54% of acid removed at 20°C compared to 60% at 60°C. Doubling or tripling the amount of water needed above a 1:0.5 ratio did not significantly affect the amount of acid removed. The model developed was significant with a predicted R2 of 96% and a root mean square error (RMSE) of 1.1 when the model was validated at different washing scenarios. Therefore, this study shows that it is possible to significantly reduce the amount of water used and processing time while maintaining resin qualities.
Insights on the distribution, catch and release and public sentiment towards recreational angling of mahseers—A study of YouTube videos from India
Authors: Das Prantik , Binoy Vilakkathala Vijayan 
Published: May 2024

Abstract
Masheers are a group of large‐bodied freshwater fishes popularly known as the ‘Tiger of Rivers’. Their size and fighting power make them one of the most popular game fishes and a dream catch of many recreational anglers in the Indiansubcontinent.
The present study explored the recreational angling (RA) videos of five mahseer species (Tor khudree [Deccan mahseer], Tor putitora [golden mahseer], Tor remadevii [humpback mahseer], Tor mosal [mosal mahseer] and Neolissochilus hexagonolepis [chocolate mahseer]) recorded from India and uploaded on the social media platform YouTube from January 2010 to October 2022. We did not come across any RA videos of T. mosal and T. remadevii; hence, further analyses were carried out on the remaining three focal species.
No seasonality was observed in the frequency of RA videos uploaded on YouTube, and T. khudree attracted the highest number of views per video. Catch and release, an ethical RA practice, was noticeably low in the case of N. hexagonolepis. The length of catch was found to be positively associated with the social engagement received by the RA videos of all three mahseer species.
Angler‐ and angling‐related remarks and words associated with positive emotions (trust, joy and anticipation) dominated the comments received by the angling videos. The results are discussed in light of the trending discourses on developing social media data as a complementary tool for monitoring and managing RA and conserving fish.
