26 Understanding STEM careers requirements of UK secondary school students
Over half of STEM careers employers have reported difficulty in recruiting workers with the correct skills (The Open University, 2019), and it has been demonstrated that engagements with schools by employers can help support students to become more career ready (The Careers and Enterprise Company, 2020). Healthcare scientists work in the NHS using STEM skills to support diagnosis, prevention and treatment of disease and injury. As a lesser known career path, engagement with schools to raise awareness of healthcare science careers is vital.An online learning needs analysis (LNA) was constructed to acquire an understanding of students learning requirements for STEM careers events, and to gain feedback on a previously recorded careers video. The LNA was distributed through a variety of social media channels.Responses were received from 111 UK secondary school students aged 11–18 from a wide range of locations and ethnic background. Responses showed that the most commonly checked social media sites were Tik Tok (90.2%), Youtube (87.5%) and Instagram (84.8%) demonstrating the best sites to target in order to engage with students.Results showed that only a third of respondents were aware of a STEM careers programme at their school, demonstrating a need to more successfully engage with students in order to encourage an interest in STEM careers.Responses to the STEM careers video were generally positive, with 97.3% rating the healthcare science information in the video at 3/5 or higher. Recommendations from the respondents showed that future videos could be more effective if they were structured to explain career entry requirements, discussions of day-to-day work and attainable career progression routes.The study highlighted the need for engagement between teaching, students and employers when discussing healthcare science careers, as well as provided suggestions for future careers resource development.
The prevalence and microbiological features of Staphylococcus species isolation from healthcare personnel in a dental clinic in Tripoli, Libya
The level of prevalence and proportional rates was calculated by descriptive analysis using Statistical Package for Social Science (SPSS) statistics for Windows version 20 (SPSS-20, IBM Corp, Armonk, NY). [...]no significant difference was identified between any of the analyzed age groups, but staphylococci carriage in the first group (18 to 25 years) was higher at a rate of 34%, and the MRS carriage in the second group (26 to 44 years) was higher at a rate of 7%. The emergence of high-level mupirocin resistance is widely attributed to the repeated and/or long-term exposure of CoNS colonizing nasal mucosa to topical and indiscriminate use of mupirocin but also indicates a potential expansion of the reservoir of MDR and transferrable molecular determinants encoding mupirocin resistance such as mupA and mupB gene [10].

Greater Social Isolation and Social Constraints Prior to Hematopoietic Stem Cell Transplant Are Associated with Greater Anxiety and Depressive Symptoms
BackgroundHematopoietic stem cell transplantation (hereafter “HCT”) is a physically and psychologically difficult treatment for patients with hematological cancers. This study examined relationships among patients’ reports of pre-transplant social isolation, social constraints, and psychological distress.MethodWe used baseline data from a multisite randomized controlled trial evaluating the effects of expressive helping writing to reduce physical and emotional symptoms in HCT patients. We collected data prior to randomization and before either allogenic or autologous HCT using validated scales to assess social constraints, social isolation, anxiety, and depressive symptoms. We analyzed data using bivariate analysis and multivariate linear regression. We also explored whether social isolation mediated the effect of social constraints on both of our outcomes: anxiety and depressive symptoms.ResultsAmong 259 adults recruited prior to transplant, 43.6% were women (mean age = 57.42 years, SD = 12.34 years). In multivariate analysis controlling for relevant covariates, both social isolation (β = 0.24, p < 0.001) and social constraints (β = 0.28, p < 0.001) were associated with anxiety. When both social constraints and social isolation were in the model, only greater social isolation (β = 0.79, p < 0.001) was associated with depressive symptoms. Social isolation fully mediated the association between social constraints and anxiety and depressive symptoms.ConclusionFor patients awaiting either allogenic or autologous HCT, the negative association between social constraints and anxiety and depressive symptoms may be related, in part, to the mechanism of perceived social isolation. Interventions prior to and during HCT are needed to support patients’ psychological health and sense of social connectedness.
Manipulating Entanglement Dynamics in Dephased Interacting Qubits Using a Radiation Field
We study the entanglement dynamics of a pair of non-identical interacting atoms (qubits) coupled off-resonance to a single-mode cavity radiation field and exposed to dephasing environments. The qubits are studied starting from various initial states that are disentangled from an initially coherent field. The system models the basic building units of quantum information processing (QIP) platforms under the realistic considerations of asymmetry and external environmental influences. We investigate how introducing a radiation field alters the system’s entanglement dynamics in the presence of dephasing environments, and how it impacts the effects of the dephasing environments themselves. The work examines the problem under various settings of inter-qubit interactions, which are now experimentally controllable in some of the newly engineered artificial qubit systems. We illustrate that only upon introducing the radiation field, the system suffers a terminal disentanglement (followed by no revivals) in a finite time. This behavior is exacerbated when the atoms’ interaction with the field is stronger. Moreover, the effects of the field’s intensity and the atoms’ detunings are vastly sensitive to the choice of the initial state. We also demonstrate that the closer the atoms’ transition frequencies are to resonance with the field, the more pronounced are the effects of strengthening the independent dephasing environments corresponding to some initial states. Those states also suffered a greater reduction in entanglement content when the qubits with stronger atom–field interaction strength were influenced by a stronger independent dephasing environment. In addition, we examined the ability of the correlated dephasing environment to induce a noise-enhanced efficiency in the presence of an external radiation field. We showed that the radiation field could play a decisive role in enabling or restricting noise-enhanced efficiency, but one that is also highly sensitive to the system’s initial state.
Efficacy of repetitive transcranial magnetic stimulation for smoking cessation: a systematic review and meta-analysis
Background Tobacco use disorder remains one of the most prevalent substances use disorders globally, contributing significantly to morbidity and mortality. While pharmacological and behavioral interventions have been effective, relapse rates remain high, necessitating the exploration of novel therapeutic approaches. One such approach is repetitive transcranial magnetic stimulation (rTMS), a non-invasive brain stimulation technique that has shown promise in various neuropsychiatric disorders, including medication-resistant conditions. Objective To evaluate the efficacy of rTMS in smoking cessation, its impact on abstinence rates, nicotine dependence, and craving. Methods We conducted a comprehensive search across multiple databases (PubMed, Scopus, Web of Science, Cochrane, PsycINFO, and Clinicaltrials.gov) from inception to August 2024. Eligible studies were randomized controlled trials (RCTs) evaluating rTMS as a treatment for smoking cessation, with outcomes including nicotine dependence, craving, abstinence, and cigarette consumption. Results We included 17 RCTs involving 859 participants were included in this review. The pooled analysis revealed a statistically insignificant reduction in nicotine dependence based on the Fagerström Test (MD = -0.40, 95% CI [-1.16 to 0.35], P = 0.30). rTMS demonstrated significant reductions in craving, as measured by the Tobacco Questionnaire for Smoking Urges (MD = -10.89, 95% CI [-12.94 to -8.85], P < 0.00001). Self-reported abstinence showed a significant improvement (RR = 1.89, 95% CI [1.12 to 3.19], P = 0.02). However, no significant effects were observed for self-reported cigarette consumption (MD = -2.74, 95% CI [-7.26 to 1.79], P = 0.24) or the Visual Analog Scale for craving (SMD = -0.29, 95% CI [-0.67 to 0.10], P = 0.14). Conclusion rTMS shows promising potential as an adjunctive treatment for smoking cessation by reducing nicotine dependence (to some extent) and improving abstinence rates. However, its effectiveness is not uniform across all smoking-related outcomes. With further research, rTMS could become a valuable component of comprehensive smoking cessation strategies.
Deep learning enabled intrusion detection system for IoT security
With the swift progress of technology and the increasing frequency of cyber attacks on organizational networks and systems, cybersecurity has become one of the most critical challenges in the modern digital world. Within this framework, Intrusion Detection Systems (IDS) are critical to mitigate the impact of cybercrimes and safeguarding systems from various malicious attacks. However, traditional machine learning (ML) approaches have ceased to be sufficient to handle the complexities of large-scale and unstructured data, particularly in Internet of Things (IoT) environments. To bridge this gap, we propose a hybrid DL-based IDS that leverages the synergistic strengths of convolutional neural networks (CNNs) and gated recurrent units (GRU). While CNNs excel at extracting spatial features from network traffic data, GRUs effectively model temporal dependencies, making their combination particularly well-suited for detecting dynamic and complex IoT intrusions. In this study, we evaluate three DL models including CNN, GRU, and a hybrid CNN-GRU approach on two recent Netflow-based datasets, NF-UNSW-NB15 and NF-CSE-CIC-IDS2018 for binary classification. Extensive experiments using accuracy, precision, recall, F1-score, False Alarm Rate (FAR), AUC, and processing time metrics show that the CNN-GRU model outperforms standalone CNN and GRU models, as well as existing literature approaches, achieving an accuracy of 98.60% on the NF-UNSW-NB15 dataset and 97.95% on the NF-CSE-CIC-IDS2018 dataset. Our findings underscore the efficacy of combining spatial and temporal DL architectures for robust IoT intrusion detection, offering a scalable solution for modern cyber threats.
Pomgulated methionil (LY2140023) in schizophrenia patients: a systematic review and meta-analysis
Background Pomaglumetad methionil (LY2140023 monohydrate) is a potent and selective agonist for metabotropic glutamate receptors (mGluR2/3). Unlike traditional antipsychotics, it does not directly interact with dopamine or serotonin (5-HT2A) receptors, potentially offering a novel mechanism of action with a different side-effect profile. We aim to provide an overview of this novel drug and evaluate its efficacy in comparison to both placebo and atypical antipsychotics by performing a systematic review and meta-analysis. Methods A comprehensive literature search was conducted to identify relevant studies. The included studies investigated the effect of Promogulated methionil. The quality of studies was assessed using the Cochrane Risk of Bias 2 (ROB-2) Statistical analysis was conducted using Review Manager (revman) with outcomes expressed as Mean differences (MD) with 95% confidence intervals (CI). Results The systematic review included 4 randomized clinical trials (RCTs). The analysis revealed that pomaglumetad methionil (LY2140023) didn’t have a statistically significant effect on PANNS compared to placebo (p-value = 0.31) and it was less effective in decreasing PANSS score in comparison to atypical antipsychotics (p-value < 0.00001). However, the drug showed a significant effect on weight gain (p-value < 0.00001) and prolactin ( p  < 0.0001) in comparison to atypical antipsychotics. Conclusions In conclusion, this systematic review and meta-analysis provide evidence that pomaglumetad methionil (LY2140023) does not demonstrate consistent efficacy in the treatment of schizophrenia. Although the compound is associated with a more favorable profile regarding weight gain and prolactin elevation, these advantages do not compensate for its lack of therapeutic efficacy.
Public attitudes and practices toward using AI chatbots for healthcare assistance: a multinational cross-sectional study
Background Using artificial intelligence (AI) chatbots in healthcare can enhance patient care. However, misuse may lead to negative outcomes. Our study’s aim is to evaluate the practices and attitudes related to AI chatbots for healthcare assistance within the general population in the Arab region. Methods A population of 12 years old and above from 21 Arab countries was invited to complete a validated web-based questionnaire from 1 May to 1 June 2024. The survey consisted of four sections: demographics, identification, attitudes, and practices related to AI chatbots in healthcare assistance. We utilized Microsoft Excel and SPSS software for data entry and analysis. Descriptive statistics, chi-square tests, and binary logistic regression were used to analyze demographic associations and usage predictors for healthcare Results Among the 12,886 valid responses, the median age was 24 years (IQR: 21–31), with a female-to-male ratio of 2:1. Most were single (66.8%), from Egypt (11.2%), urban residents (81.2%), students (43.6%), university-educated (73.2%), or healthcare-affiliated (40.2%). While 72.5% were aware of AI chatbots, only 26.4% used them, primarily for health coaching (67.5%), self-medication (54.5%), self-diagnosis (44.1%), and mental support (48%). ChatGPT was the most used chatbot (22.65%) for healthcare assistance. Individuals with psychological or mental health issues had greater odds of chatbot use (Exp(B) = 1.343, 95% CI: 1.189–1.516, p  < 0.001), while the strongest predictor was participation in AI-related training courses, which was associated with more than a threefold increase in odds (Exp(B) = 3.109, 95% CI: 2.715–3.559, p  < 0.001). Conclusion This study highlighted varying attitudes and patterns regarding the use of AI-powered chatbots for healthcare assistance, from consultation to self-diagnosis and medication. The insights from this study can help policymakers, researchers, developers and healthcare professionals integrate AI chatbots more effectively into the existing healthcare system.
