Evaluating the Antibacterial Properties of a Zeolite-Chitosan Biocomposite for Medical Applications

: Antibacterial substances have garnered significant interest in recent years due to their applications in medical equipment, prostheses, and drug delivery systems. Consequently, it is essential to identify and develop biomaterials with antibacterial properties tailored to specific target sites. This study utilizes two natural biomaterials: Chitosan and zeolite. Zeolite, a bioceramic with an aluminosilicate structure, exhibits high mechanical resistance, making it ideal for use in areas of the body that endure significant pressure, such as bones and teeth. Chitosan, on the other hand, possesses excellent properties for application in various bodily tissues. However, natural polymers like chitosan are often combined with other materials in composites to enhance their mechanical resistance. This research investigates the antibacterial properties of a biocomposite made from zeolite and chitosan against two types of bacteria: Staphylococcus aureus (gram-positive) and Escherichia coli (gram-negative). The results revealed that the composite exhibited strong resistance against E. coli but comparatively lower resistance to S. aureus. Furthermore, the findings suggest that chitosan plays a more significant role in conferring these antibacterial properties.

On the Possibilities and Significance of Unmanned Aerial Vehicles for the Pre- Hospital Stage of Medical Care

Unmanned aerial vehicles are an important force in search and rescue operations. They help reduce the time needed to search for and provide assistance to the wounded, sick and injured who are located at a large territorial distance and in hard-to-reach places. With the help of computer “vision” and sensors such as noise sensing, binary sensing, vibration and thermal sensing, drones are able to search for living patients not only in the sea, high in the mountains and in mines, but also buried under the rubble of buildings and structures. Such devices demonstrate advantages in emergency and urgent delivery of medical resuscitation and other medical equipment, medicines, blood products and organs for transplantation to patients, especially those in remote locations. With the help of drones, it is possible to effectively sort patients in case of mass sanitary losses, carry out disinfection and remotely monitor the health status of patients with highly contagious infectious diseases and other pathological conditions, as well as reduce the time for providing other medical and humanitarian services to the population. It is obvious that the use of drones requires further study of their promising capabilities, especially in the actual conditions of emergency medical services.

Teachers’ Utilization of Information and Communication Technology and Learners’ Academic Performance

Several novel concepts and understandings in education can result from researching how teachers use information and communication technology (ICT) and how that use affects students’ academic achievement. It is on this premise that this paper aimed to determine the extent of teachers’ ICT utilization and its relationship with learners’ academic in a public secondary school, in one of the districts of a large size schools division in Central Philippines, during the School Year 2023-2024. Data needed for this descriptive study was collected from 42 respondents using a self-made 30-item questionnaire that has passed the rigorous tests of validity and reliability. This study employed appropriate statistical methods based on the stated objectives namely, frequency and percentage count, Mean, Mann-Whitney U-test and Spearman Rho. Data showed a great extent of teachers’ ICT utilization when analyzed regarding instructional delivery and computer peripherals and equipment. Meanwhile, learners’ academic performance was found to be very satisfactory. The results state that the relationship between extent of teachers’ ICT utilization in teaching and learners’ academic performance is interpreted as not significant, the extent of teacher’s utilization of Information and Communication Technology does not affect the learners’ academic performance. The study results call for the teachers to encourage using technology in delivering the lesson, and the higher authority may support the school in providing the needs of the teachers and students and equip educators with tangible abilities to enhance technology integration in classrooms, fostering creativity, collaboration, and continuous refinement of teaching and learning approaches.

Exploring the feasibility of home-delivered capsule endoscopy with 5G support: innovations and carbon footprint insights.

Colorectal cancer (CRC) poses a significant global health threat, necessitating early detection. Traditional diagnostic tools like optical colonoscopy have limitations prompting our '5G-SUCCEEDS' initiative to explore a novel approach involving remote colon capsule endoscopy (CCE). This prospective feasibility study was conducted at a single hospital in England. Between December 2022 and September 2023, we introduced a remote CCE service within the 5G-SUCCEEDS framework. We undertook a feasibility study of CCE in patients with low-risk/moderate-risk CRC stratified by faecal haemoglobin. Outcomes included carbon footprint analysis (outlined through three potential clinical pathways) and patient-reported outcomes through structured questionnaires and interviews. Among 25 participants, 88% expressed satisfaction with remote CCE. 82% were willing to have remote CCE if clinically indicated in future. CCE findings included adenomatous polyps (58%), normal results (17%) and diverticulosis (21%), with no cancers identified in this pilot. Notably, we found that the carbon footprint associated with delivery of CCE at home (pathway 3) was lower compared with CCE delivered in a clinical setting (pathway 2). A fully optimised, automated scaled-up pathway would combine the delivery and collection of CCE equipment within a local area to reduce the carbon footprint of the travel element by 75%. Moreover, the conversion rate into a colonoscopy pathway is not static and clinicians acknowledge that this could be as low as 28%. Carbon footprint is more favourable for home-delivered CCE in the optimised scenario, while less so when considering the need for additional procedures (colonoscopy conversion). The 5G-SUCCEEDS initiative highlights the feasibility and advantages of home-based diagnostics using CCE.

Virus-like Particles for Disease Diagnosis and Drug Delivery Applications

Abstract: Virus-like particles (VLPs) are nanoscale, self-assembling cage structures made out of proteins with practical uses in biomedicine. They might be used to create better vaccinations, imaging equipment, gene and drug therapy delivery systems, and in vitro diagnostic equipment. VLPs are nanostructures that might be used in medicine, immunization, and diagnostics, among other areas. Many VLPs-based vaccines are now in use for the treatment of infectious diseases, and many more are on their way to clinical testing thanks to recent advancements in biomedical engineering. Although VLPs exhibit promising qualities in terms of efficacy, safety, and diversity, they may become more widely used in the future. Vaccines based on virus-like particles (VLPs) might serve as an effective addition to current immunization strategies for the prevention and treatment of emerging infectious diseases. The growing field of healthcare prevention has become increasingly interested in VLPs, leading to the discovery of various VLP-based candidate vaccines for vaccination towards a wide range of infectious pathogens, one of the most recent that has been developed is the vaccine against SARS-CoV-2, the effectiveness of that is now being tested. VLPs can elicit both antibody and cell-mediated immune responses, unlike standard inactivated viral vaccines. However, several problems persist with this surface display method and will need fixing in the future. VLPs-based medicinal delivery, nanoreactors for treatment, and imaging systems are being developed with promising results. The latest developments in the generation and fabrication of VLPs involve explorations of several expression systems for their creation and their application as vaccines for the avoidance of infectious diseases and malignancies. This manuscript offers the most advanced perspective on biomedical applications based on VLPs, as well as details innovative methods for manufacturing, functionalization, and delivery of VLPs.

Oxygen delivery and monitoring in neonatal intensive care units in Mexico in 2011 and in 2023: an observational longitudinal study

BackgroundRetinopathy of prematurity (ROP) is a leading cause of avoidable blindness in children, particularly in Latin America, where hyperoxia is a significant risk factor. This study evaluated resource availability and use for administering and monitoring supplemental oxygen in Mexico.MethodsIn 2011, an observational study in which 32 government neonatal intensive care units (NICUs) across Mexico were visited. Data collected included occupancy, staffing levels, and equipment to deliver and monitor supplemental oxygen. Preterm infants receiving oxygen were observed. In 2023, 13 NICUs were revisited, and similar data collected. Staffing levels were benchmarked against Argentinian and US recommendations.ResultsIn 2011, only 38% of NICUs had adequate medical and staffing levels to meet recommended cot-to-staff ratios for all shifts. Staffing ratios were worse during weekends and at night than during weekdays. Only 25.5% of cots had blenders, and 80.1% had saturation monitors. 153 infants were observed 87% of whom were being monitored. Upper and lower oxygen saturations were ≥ 96% in 53%, and ≤ 89% in 8%, respectively. Alarm settings were inadequate, as 38% and 32% of upper and lower alarms were switched off and 16% and 53% were incorrectly set, respectively. In the 13 NICUs with data from 2011 and 2023, cot-to-staff ratios deteriorated over time, and in 2023 no unit had recommended ratios for all shifts. Equipment provision did not change, with similar proportions of babies in oxygen being monitored (79% 2011; 75% 2023). Rates of hyperoxia decreased slightly from 54% in 2011 to 49% in 2023. More upper alarms were set (46% 2011; 75% 2023), but a higher proportion were incorrectly set (52% 2011; 68% 2023).ConclusionsBetween 2011 and 2023, cot-to-staff ratios worsened, and equipment for safe oxygen delivery and monitoring remained insufficient. Despite available monitoring equipment, oxygen saturations often exceeded recommended levels, and alarms were frequently not set or incorrectly configured. Urgent improvements are needed in healthcare workforce numbers and practices, along with ensuring adequate equipment for safe oxygen delivery.

A home healthcare routing-scheduling optimization model considering time-balancing and outsourcing

Home care services have a significant role in lowering healthcare expenditure. Supply chain management in home healthcare (HHC) ensures efficient delivery of medical supplies and equipment to patients' homes, improving overall quality of care and patient outcomes. This study proposes a routing and scheduling optimization model for HHC by prioritizing patients, developing an effective delivery strategy, and considering home care logistics and services. The model primarily concerns reducing logistics activities’ overall expenses while considering patients’ priorities. A bi-objective optimization model for a multi-period HHC problem is developed by prioritizing patients with urgent critical needs. The best-worst method (BWM) and technique for order of preference by similarity to ideal solution (TOPSIS) are used to prioritize patients using a linear programming metric (Lp-metric). The BWM and TOPSIS have been uniquely used in this study for routing and scheduling in HHC. Eventually, the applicability of the proposed method is demonstrated through a real-life case study with a series of numerical examples and sensitivity analysis. For instance, by analyzing privilege, we see patients are carefully matched with caregivers possessing advanced skills, leading to increased patient satisfaction. Based on assigned routes, caregivers prioritize patients with higher weight and emergency conditions at the start of each path, followed by patients with less urgent conditions. This ensures that patients with more severe conditions are serviced first.

Sensitivity analysis and optimization of heat transfer in the time-reliant magnetohydrodynamic bioconvective flow of radiative couple-stress hybrid nanofluid through a squeezing channel with viscous dissipation: Entropy analysis

This research presents a statistical investigation of heat transmission in the time-reliant flow of blood-based hybrid nanofluid-containing microorganisms via a squeezing permeable channel utilizing a couple-stress non-Newtonian fluid model. Nanoparticles of SWCNT (single-wall carbon nanotubes) and MWCNT (multi-wall carbon nanotubes) are incorporated in the base liquid due to their low toxicity, special physio-chemical characteristics, and suitable surface modifications. In addition, chemical reactions, heat sources and sinks, radiation, viscous dissipation, and an external magnetic field impact the flow. The current numerical study stands out because it optimizes heat transmission rate using a face-centered central composite design framework with RSM (Response Surface Methodology) and analyses its sensitivity toward effective parameters. Examining the system's efficiency by evaluating the entropy produced in the flow process is another noteworthy part of this research. The complex system of interrelated non-linear partial differential equations is converted into a set of ordinary differential equations using suitable transformations. Later, solved via a semi-analytical technique, HAM (homotopy analysis method). According to the outcomes of the comparison, the hybrid nanofluid (blood/SWCNT-MWCNT) outperforms the nanofluid (blood/SWCNT) in terms of thermal performance. The rates of thermal energy transmission are very sensitive to the Eckert number and somewhat least affected by thermal radiation. Nanofluids and hybrid nanofluids have their heat transmission rates improved by including nanoparticles, heightened radiation, and magnetic effects. The system produces more entropy when the magnetic parameter and Eckert number are higher; however, it can be minimized by controlling the radiation effect. The results have important consequences for engineering industries, especially in the development and improvement of biomedical equipment and drug delivery systems, where accurate management heat transfer is crucial.

Analysis of the pressure drop of sulfur hexafluoride (sf6) gas in a circuit breaker 150 KV Siemens 3AQ1EG

Abstract. The development of technology in the current era is very rapid and has an impact on increasing electrical energy which is a major need for large industries and households. One of the electrical energy delivery equipment in the transmission system is a PMT or High Connection Breaker. This PMT is a mechanical equipment equipped with sulfur hexafluoride (SF6) gas arc extinguishing media. The process of extinguishing the arc occurs due to contact due to work from the movement that causes the contact to cause an arc. This decrease in SF6 gas pressure greatly affects reliability when operating, because the arc extinguishing process is not perfect. This is determined by the age of the equipment and the number of operating breakers. The results showed that SF6 gas which is in accordance with the standard normal pressure of 6.4 bar with an ambient temperature of 34°C can minimize the occurrence of equipment damage because it is able to approach arc pressure with SF6 gas velocity of 58 cm/s.kA, with a contact gap of 3,61224. cm, while the PMT cannot be operated at a pressure of 5.2 bar with an ambient temperature of 34°C because the speed of SF6 gas is 82 cm/s.kA with a contact gap of 5.10696. It is concluded that the higher the pressure affects the speed and distance when extinguishing the arc. several factors that affect the decrease in SF6 gas pressure using the FMEA method based on the highest value of the Risk Priority Number (RPN) of 810.

ZOom Delivered Intervention Against Cognitive decline (ZODIAC) COVID-19 pandemic adaptations to the Post-Ischaemic Stroke Cardiovascular Exercise Study (PISCES): protocol for a randomised controlled trial of remotely delivered fitness training for brain health

BackgroundStroke increases subsequent dementia risk yet there are no specific post-stroke therapies to protect cognition. Cardiorespiratory exercise is recommended for secondary prevention of stroke and may be neuroprotective. The Post Ischaemic Stroke Cardiovascular Exercise Study (PISCES) aims to reduce post-stroke secondary neurodegeneration and cognitive decline. During the pandemic, we pivoted to a ZOom Delivered Intervention Against Cognitive decline (ZODIAC) protocol, reducing pandemic-amplified barriers to exercise.MethodsWe present pandemic adaptions for a multicentre phase IIb assessor-blinded randomised controlled trial of ischaemic stroke survivors testing the efficacy and feasibility of an 8-week home-based exercise intervention delivered at 2 months post-stroke. We compare cardiorespiratory exercise (intervention arm) versus balance and stretching (active control arm). Participants are assessed with magnetic resonance imaging (MRI), fitness, blood, microbiome, and neuropsychological tests at three study visits: before and after the exercise intervention and at 12 months. Modifications to the original protocol include pre-exercise safety home visits, commercial delivery of exercise equipment to facilitate assessor blinding, and reconsideration of statistical plan to allow pooling of the studies. We have reduced in-person study visits from 27 to 3. Primary outcome remains between-group (intervention versus control) difference in brain volume change; secondary outcome is between-group difference in global cognitive ability to allow remote administration of a validated cognitive scale.DiscussionRemotely delivered exercise interventions reduce participant burden and may reduce barriers to recruitment. A decrease in the number of in-person study visits can be supported by greater information capture via self-reported questionnaires and phone surveys.Trial registrationProspectively ACTRN12616000942459.

ANALYSIS OF THE CHARACTERISTICS AND CAPABILITIES OF MODERN VIBRATION AND STRAIN GAUGES OF MODERN MEASURING EQUIPMENT

The article analyses the characteristics and capabilities of modern vibration and strain gauges, as well as the existing requirements for vibration measurement devices for wheeled armoured vehicles. The main physical parameters for assessing the strength and vibration characteristics of wheeled armoured vehicles to be measured are determined. Modern accelerometers for measuring vibration have better universal characteristics compared to other types of sensors, as well as a wide frequency and dynamic linearity range. The use of piezoelectric, strain gauge, magnetic induction and laser measuring equipment will allow to obtain physical values of vibration parameters and the stress-strain state of wheeled armoured vehicles and, using data acquisition systems and software, to analyse deviations of limit values in the design and components of the vehicle.
 Improvement of the methodological apparatus for experimental studies of strength and vibration characteristics during testing of wheeled armoured vehicles will improve the quality and simplify the measurement process, which in turn will significantly reduce the time for testing prototypes and ensure timely delivery of weapons and military equipment (components) to the Armed Forces of Ukraine. The use of modern vibration and strain gauges to assess the strength and vibration characteristics of structures and their components will simplify and automate the measurement process, minimising possible errors during testing of armoured vehicles. The results of the work can be used for a rational and justified selection of vibration and strain gauges for testing wheeled armoured vehicles.
