Oral mucositis is a frequent and debilitating adverse event observed in patients undergoing chemotherapy or radiotherapy. Current management strategies are limited in duration, require frequent application, and fail to address the mechanical irritation from teeth. A novel device, Soft Protector CPC, was developed to overcome these limitations. This multicenter, randomized, two-arm, open-label, confirmatory trial aims to evaluate the efficacy and safety of Soft Protector CPC in patients with breast cancer undergoing chemotherapy. A total of 154 participants will be randomly assigned in a 1:1 ratio to receive either oral care with Soft Protector CPC or oral care alone. The primary endpoint will be oral mucositis as assessed according to the Common Terminology Criteria for Adverse Events (CTCAE) v3.0 during the comparative treatment period. The secondary endpoints will include CTCAE v3.0 during the continuous treatment period, oral mucositis, pain (CTCAE v5.0), quality of life (Patient Reported Outcomes-CTCAE version 1.0 [PRO-CTCAE v1.0], the 15-item oral health questionnaire of the European Organization For Research And Treatment Of Cancer [EORTC QLQ-OH15], and the pain Numeric Rating Scale), onset and site of mucositis, completion of chemotherapy, use of rescue medications, technical feasibility, and patient preference. The safety endpoints will include adverse events, device malfunction, and laboratory tests. This trial is expected to establish the clinical utility of the Soft Protector CPC for the prevention and management of oral mucositis, with the potential to improve the patients’ quality of life and adherence to cancer therapy. This study was approved by the Clinical Research Review Board and registered with the Japan Registry of Clinical Trials, jRCTs062250005, on April 18, 2025.by Linda Abou-Abbas, Rima Kashash, Mustapha Khalife, Mohamad Shafic Ramadan
BackgroundEffective preparedness and response to mass casualty incidents (MCI) are essential for hospital safety, operational efficiency, and the delivery of timely, high-quality patient care during emergencies. This study assessed a tertiary government hospital in Lebanon’s Code Orange plan by reviewing documentation for alignment with international guidelines and evaluating staff knowledge, attitudes, and practices (KAP) regarding MCI preparedness.
MethodsDocuments reviewed at Rafik Hariri University Hospital (RHUH) included the current Code Orange plan, relevant policies, and international guidelines. A comprehensive evaluation framework was used, focusing on preparedness, incident command systems, communication, and management. A comparison with established standards was conducted to identify gaps. Complementing this, a cross-sectional study was conducted using a convenient sample of medical and non-medical healthcare workers to evaluate their KAP regarding MCI preparedness.
ResultsThe desk review of the RHUH Code Orange plan identified both strengths and significant gaps in MCI preparedness. While the plan defines staff roles and resources for emergency response, it lacks detailed procedures for activation strategies, surge capacity, continuity of essential services, and triage processes. Additionally, post-event recovery protocols are insufficient or absent, and the importance of regular drills is not adequately emphasized. The KAP study revealed significant differences between medical and non-medical staff in terms of MCI knowledge, involvement, and training engagement, with medical staff reporting higher levels of familiarity and desire for participation.
ConclusionThe findings underscore the need to bridge knowledge and engagement gaps between medical and non-medical staff to enhance MCI response. Key actions include interdisciplinary training to build coordination, clear communication protocols to streamline information flow, and routine drills with defined roles to strengthen preparedness. Additionally, implementing performance monitoring during drills and real MCIs, along with conducting regular evaluations, will allow for continuous refinement of response strategies.

Construction projects are exposed to numerous risks that may adversely affect project cost and duration. The purpose of this study is to identify and prioritize key construction risks by combining a Work Breakdown Structure (WBS) with a Risk Breakdown Structure (RBS) and analyzing these risks using two-dimensional (2D) and three-dimensional (3D) risk matrices. In total, 63 risk factors were identified and categorized into five main areas of the work breakdown structure: earthwork, concrete, finishing, mechanical, and electrical. The questionnaire was designed based on each risk category and then sent to engineers, who were asked to estimate the risk probability and its impact. In total, 378 engineers responded. The respondents data were analyzed by using the risk matrix method. Two separate 3D risk matrices were made: one was based on multiplying all three data points, and the other was based on combining both impacts. The results clearly show that the 3D matrix, which combines cost and time impact, yields more accurate results than the matrix that multiplies cost impact and time impact.by Riham M.

BackgroundToday, community pharmacists’ responsibilities have expanded beyond the traditional role to include the management of minor ailments. Acute uncomplicated cystitis is one of the most prevalent medical conditions seen in primary healthcare and can be managed by community pharmacists (CPs).
ObjectivesTo evaluate community pharmacists’ history-taking practice when responding to patients with acute uncomplicated cystitis.
MethodsA cross-sectional simulated patient study was conducted from November 2022 to January 2023 in Khartoum locality targeting only pharmacists. Six trained female students played the simulation in which they pretended to have the clinical symptoms of acute uncomplicated cystitis and requested treatment for their condition. The Interactions during the simulation were documented immediately in a data collection form after each visit. Descriptive statistics were used to report the study outcomes.
ResultsA total of 238 community pharmacies were visited. The majority of the pharmacists were female. The mean of the number of questions that were asked by the pharmacists was 1 (SD = 1.6) questions. Among the studied pharmacists, 45.4% asked at least one question during patient assessment. The most asked question was if the patient has a fever, representing 61 (25.6%) CPs, followed by if there is vaginal discharge, representing 38 (16%) CPs. In response to scenario 47 (19.7%) CPs decided to refer the patient to a physician, and 45 (18.9%) of the CPs advised the patient to increase water intake.
ConclusionsThe study has revealed a poor history-taking practice towards acute uncomplicated cystitis during patient assessment. Further studies exploring pharmacists’ involvement in patient assessment are required. Strategies to improve community pharmacists’ practice, like continuing pharmacy education and providing a national guideline regarding patient assessment should be considered seriously.

The chemical composition of the venom in social Hymenoptera differs between castes and ages. Biogenic amines are contained in the venom of honey bees and may be physiologically effective to vertebrate predators and insects. This study quantified the concentrations of biogenic amines in venom and compared them between different castes and ages of honey bees. The concentrations of dopamine and N-acetyldopamine in venom were significantly higher in virgin queens than workers of the same age. The concentrations of dopamine, norepinephrine, tyramine and serotonin increased with age in virgin queens and workers. There was a significant positive correlation between venom dopamine concentrations and ovarian development in queenless workers, suggesting that the concentration of dopamine in the venom transformed from normal workers to reproductive females as that in virgin queens. We also tested the possibility of dietary effects on the concentration of dopamine in venom. Workers fed tyrosine or royal jelly showed significantly higher concentrations of dopamine precursors, tyrosine, 3,4-dihydroxyphenylalanine (DOPA) and dopamine in the hemolymph, as well as higher concentrations of dopamine in venom than in controlled workers. These results suggest that compositions of biogenic amines in venom are influenced by nutrition and change based on their social roles in honey bee society.by Michele Letitia Tchabou Tientcheu, Pierre Marie Kaktcham, Edith Marius Foko Kouam, Laverdure Tchamani Piame, Lysette Chabrone Djodjeu Kamega, Aarzoo , Agnihotri Shekhar, Singh Bhim Pratap, François Zambou Ngoufack
Conventional culture media such as de Man, Rogosa and Sharpe are essential for the growth of lactic acid bacteria and the production of metabolites used in the food and pharmaceutical industries. However, their high cost limits their application, particularly in low and middle-income countries. This study aimed to develop a cost-effective and efficient culture medium based on agro-industrial and environmental by-products, pineapple peels, sugarcane molasses, and black soldier fly larvae cake. After physico-chemical analysis of the by-products, excluding sugarcane molasses, a statistical mixture design was used to determine the optimal proportions for supporting lactic acid bacteria growth and bacteriocin production. Growth and metabolite production were monitored via plate count and agar well diffusion assays respectively. The strains tested belonged to the genera Lactobacillus, Bifidobacterium, Streptococcus, Lactococcus, and Bacillus as an out taxa group. The larvae cake showed high protein (48.47 ± 0.14%) and amino acid (17 types) content, while pineapple peels and molasses were rich in carbohydrates (89.52 ± 0.16% and 86.86 ± 0.07%). Based on regression models, the compromise formulation was defined as 55.15% larvae cake hydrolysate, 19.85% pineapple peel hydrolysate, and 25.00% sugarcane molasses. This medium highly supported lactic acid bacteria growth (9.43–9.86 log CFU/mL) compared to MRS and M17 (9.20–9.69 log CFU/mL), with Lactobacillus strains performing better. It also supported bacteriocin activity (11.0–14.5 mm inhibition zones), higher or similar to MRS and M17, with Lactococcus lactis subsp. lactis MA2 exhibiting the strongest effect. These results highlight the potential of this formulation as a sustainable, low-cost alternative for microbiology and biotechnology, particularly in resource-limited settings. The determination of its formula will allow its manufacture once the proximate compositions of the ingredients are known, regardless their origin. Future investigations will focus on optimisation of culture conditions, powder form formulation, and cost evaluation.by Mohamadreza Hatefi, Seyedeh Feriyal Mahdavi, Amirreza Abbasi, Farideh Babakhani
BackgroundUpper extremity (UE) dominance is often defined by self-reported hand preference; however, this may not accurately reflect true functional or strength-based dominance. This study examined the relationship between writing hand, throwing hand, and maximal grip strength to assess how these measures align.
MethodsThirty-four healthy, recreationally active college-aged individuals reported their preferred writing and throwing hands and completed standardized grip strength testing. Associations among the variables were analyzed using Phi coefficients and chi-square tests.
ResultsA moderate, significant relationship was found between writing and throwing hand preference (φ = 0.456; p = 0.008), indicating general consistency across these subjective measures. However, no significant association emerged between grip strength dominance and either writing (φ = 0.027; p = 0.876) or throwing hand (φ = 0.096; p = 0.574).
ConclusionThese results suggest that grip strength dominance may not correlate with commonly used indicators of hand preference, highlighting the need for task-specific definitions of dominance in clinical and athletic contexts. Consequently, employing such task-specific definitions allows for more accurate assessments and enhances the translational relevance of research findings in practical settings.

BackgroundCapacity for elective general surgical care is an important reflection of a health system’s ability to meet a population’s surgical needs and is currently known to be inadequate in many low- and middle-income countries. Patient agency is a key, understudied factor which shapes how and when patients ultimately decide to engage with formal care. Understanding factors which influence patient care seeking activity can have important implications for how current and future health systems may be utilized. This study aims to explore how patients approach the navigation and triage of their elective hernia condition within the Kenyan surgical care system.
MethodsWe conducted a qualitative study of 38 convenience-sampled patients diagnosed with an elective hernia condition at a tertiary referral hospital in Kenya between November 2023 and March 2024. We utilized Braun and Clarke’s six-step model of thematic analysis to generate key themes across the phases of care seeking, reaching and receiving as modeled in the Three Delays Framework.
ResultsWe identified three main cross-cutting themes including (1) the flow of power from patients to providers, and vice versa, take the form of consent or knowledge, respectively; (2) trust is a limited currency required for patients to engage with formal care; and (3) internal and external contextual factors remain the foundation for patient-provider care activities. We incorporated these themes together in a framework which illustrates the cyclical nature by which each factor feeds back on the others, ultimately affecting patient care.
ConclusionsFluctuating flows of patient power and trust interacts with existing infrastructural context to influence the ability of a health system to generate care. Recognizing the interaction of these key factors may have important bearing on the successful implementation of any larger systemic efforts or policies to improve access to elective surgical care.
