Extended and expanded role of nurses in antimicrobial stewardship program: A review

Antimicrobial resistance is a significant healthcare concern in this century, marked by the emergence of multidrug-resistant microorganisms. An antimicrobial stewardship program, while an innovative approach to mitigating the global threat of antimicrobial resistance and its effects on public health, is also an absolute need of the hour. When implemented effectively, such a program, in conjunction with selecting the appropriate drug, determining the correct dosage and route of administration, and integrating with an infection control program, has proven to be an effective method for curbing the rapid emergence and transmission of antimicrobial-resistant pathogens. Partnerships with nurses to strengthen antimicrobial stewardship programs in healthcare have recently gained recognition, especially in the backdrop of increased antimicrobial resistance in developing countries. Traditionally, stewardship activities have involved only prescribers and pharmacists, but including nurses in these efforts has become increasingly important. Highlights of nurse-driven antimicrobial stewardship activities include effective assessment of allergies, meticulous sampling for blood and urine cultures, antibiotic de-escalation, and 24-hour monitoring of patient status. Antibiotic or general ward rounds provide unique opportunities for nurses to influence the indication and duration of antimicrobial treatment. Including nurses in antimicrobial stewardship programs will make the management of antimicrobial therapy robust and empower healthcare institutions to approach the prevention of AMR with truly multi-disciplinary strategies. Antimicrobial stewardship is often redundant and centered around doctors in tertiary care centers. However, active participation by nurses in both healthcare facilities and community settings is crucial for making Antimicrobial stewardship practice (AMSP) a reality. Scalable nursing involvement in antimicrobial stewardship is essential for developing and developed nations to combat AMR effectively.

Extracting an accurate river network: Stream burning re-revisited

Extracting river networks that are both accurate and topologically connected is important for applications that involve correct routing of material, for example water and sediment, through such networks. We combined water and sediment extraction using radar and multispectral imagery from Sentinel-1 and Sentinel-2 to create both water and sediment masks over a range of study areas. These were then used to condition topographic Digital Elevation Models (DEMs) by lowering the elevation of pixels with both water and sediment present, in a process known as stream burning. We examined how stream burning could improve accuracy of extracted networks and identified the most effective method of burning for optimal results. We find deeper burning depths improved accuracy, with diminishing returns: we suggest burning 40 to 50 meters. We find sediment burning improves accuracy in humid and temperate landscapes, but arid landscapes should be burned using only water pixels. We find accuracy of extracted networks is significantly better on the COP30 global topographic dataset compared to the NASADEM dataset, mainly due to the time of collection. The AW3D30 DEM and FABDEM datasets have accuracies just below that of the COP30 DEM.

The Effect of Herding Behavior on the Efficiency of Pedestrian Evacuation in Subway Stations

In the emergency evacuation of pedestrians in subway stations, most people do not know the correct evacuation routes and methods, and tend to follow others blindly, resulting in herding behavior. To study the process of pedestrian evacuation with herding behavior in subway stations, a cellular automata pedestrian evacuation model is established to simulate the pedestrian evacuation with herding behavior in subway stations, and the effects of the weight coefficients of the parameters in the model on the overall evacuation time and the distribution of people’s positions are investigated to quantify the effects of herding on the efficiency of the pedestrian evacuation and the movement behavior. The simulation results show that moderate (kC < 40) crowd behavior can play a beneficial role in reducing reaction time and guiding the direction of evacuation; on the contrary, excessive crowd behavior (kC > 40) will lead to an increase in evacuation time and a decrease in evacuation efficiency. The conclusions presented in this paper can help to improve the efficiency of pedestrian evacuation in emergencies and provide a theoretical basis and practical guidance for the management of safety evacuation in subway stations.

Analisa Kinerja Protokol Routing Destination Sequenced Distance Vector Di Jaringan VANET

Vehicular network is a network where vehicles communicate via an ad-hoc network system that runs based on certain ad-hoc routing protocols. A vehicle ad-hoc network consists of two communication parts known as vehicle-to-vehicle communication and vehicle-to-infrastructure communication. Even though the roads have become very congested with many vehicles, controlling vehicle movement has become an urgent need. Automatic traffic control, critical moment notifications, post-accident notifications, correct route selection become very important and these can be implemented using vehicle ad-hoc network systems. For good communication between vehicles, vehicle ad-hoc networks use several protocols. One of the problems faced by VANET is routing. Routing in VANETs can perform challenging tasks due to high mobility, network topology interference, and path selection processes. DSDV is one of the routing used in VANET and simulations were carried out with NS2 to obtain DSDV routing performance in the VANET network based on quality of service with scenarios of 25 and 33 nodes. DSDV routing was chosen because it has the best performance in its class. From the simulation results, the end to end delay for 25 nodes is 22.22 and 33 nodes is 24.07, the packet drop obtained for 25 nodes is 0.85, and 33 nodes is 0.80. Furthermore, the throughput value obtained in the simulation for 25 nodes is 274.19 and 33 nodes 351.12, then the packet delivery ratio for 25 nodes is 2990, and 33 nodes is 4888

THE START SORTING SYSTEM AND THE NURSE’S PARTICIPATION IN ITS IMPLEMENTATION

Introduction. This article highlights the problem of organizing the sorting of patients during mass admission to medical institutions and providing emergency medical care. The role of the nurse in conducting triage and providing emergency care at the early hospital stage is within the framework of limited resources. The urgency of working out the response protocol in the event of an emergency. The aim of the study – to determine the role of the nurse in the triage and provision of emergency care at the early hospital stage within the framework of a limited resource. To establish the relevance of the use of the START medical triage system in the practical activities of a nurse. The relevance of working out the response protocol in the event of an emergency among nurses. The main part. The medical triage system START (Simple Triage and Rapid Treatment) is an effective tool for organizing and accelerating the process of correct routing of patients in mass cases and crises when resources are limited and medical needs are high. Medical triage criteria also include signs of primary medical examination. As their professional responsibilities expand, nurses can use the ABCD algorithm to assess the patient’s condition. Knowledge of the principles of this medical triage system, the ability to provide emergency medical care, evenly and effectively distribute resources, follow the instructions of the coordinating physician, describe medical documentation, and label the patient’s category have become the duties of nurses due to the increasing frequency of emergencies. Conclusions. The START (Simple Triage and Rapid Treatment) triage system is used for prompt and efficient selection of victims during emergencies. The role of the nurse in this process is extremely important. First of all, the nurse must have skills in the application of the START triage technique and an understanding of its basics. During triage, the nurse can quickly assess the condition of each victim, determine the category, and assign the appropriate color tag. Provision of emergency medical care in conditions of limited resources, coordination, and reporting for further organization of medical care are key elements in the formation of nursing competence during triage. Using the principles of medical triage can help optimize treatment and save more lives in emergencies.

Dual function of a highly conserved bacteriophage tail completion protein essential for bacteriophage infectivity

Infection of bacteria by phages is a complex multi-step process that includes specific recognition of the host cell, creation of a temporary breach in the host envelope, and ejection of viral DNA into the bacterial cytoplasm. These steps must be perfectly regulated to ensure efficient infection. Here we report the dual function of the tail completion protein gp16.1 of bacteriophage SPP1. First, gp16.1 has an auxiliary role in assembly of the tail interface that binds to the capsid connector. Second, gp16.1 is necessary to ensure correct routing of phage DNA to the bacterial cytoplasm. Viral particles assembled without gp16.1 are indistinguishable from wild-type virions and eject DNA normally in vitro. However, they release their DNA to the extracellular space upon interaction with the host bacterium. The study shows that a highly conserved tail completion protein has distinct functions at two essential steps of the virus life cycle in long-tailed phages.

Effects of Inadvertent Oral Ingestion of Jatyadi Oil

Ayurveda offers various formulations for different ailments, including Jatyadi oil, a topical medicine commonly used for wounds and ulcers. While it’s local application is well-documented for conditions like sinuses, papules, dermatitis, wounds, ulcers, burns, and abrasions, its oral ingestion is not standard practice due to potential adverse effects. Objective: This report aims to highlight the consequences of inadvertent oral ingestion of Jatyadi oil by a patient. Methods: The case report is based on a real-life incident involving a patient who mistakenly ingested Jatyadi oil. The effects were studied by discussing the matter with the patient and reviewing relevant literature. Conclusion: While medications are meant to heal, incorrect usage can lead to harm. Although accidental oral intake of Jatyadi oil may not be overly concerning, it is crucial to avoid such occurrences. Patients should be properly instructed regarding the correct dose, route, and method of medication intake to prevent such incidents.

Drug prescription awareness among dental students in Kerala: a survey of current knowledge and awareness

Background: Prescribing medicine is a core skill for dentists, impacting patient safety and requiring knowledge of medications, dosages, and risks. This study evaluates dental students' awareness of these critical aspects in Kerala, India. Methods: This study aimed to assess drug prescription awareness among dental students in Kerala, India, highlighting current knowledge, standard practices, and areas for improvement. Results: Dental pain emerged as the most commonly treated condition (57.7%), with Amoxicillin reigning as the antibiotic of choice (69.2%-76.3%). Textbooks reigned supreme as the primary source of prescription information (66.4%-58.3%), even as most participants (78.1%-72.4%) acknowledged the WHO prescribing guidelines. While interns demonstrably boasted greater confidence in their knowledge, nearly half of all participants grappled with a lack of confidence in drug dosage and frequency. Incorrect dosage stood out as the Achilles' heel of prescription practices (71.9%-77.6%). Strengths included awareness of the correct route of delivery (61.6%-74.4%) and adherence to WHO guidelines. Conclusions: Dental students in Kerala demonstrate fair drug prescription awareness but have gaps in knowledge regarding dosage, frequency, and duration. Textbooks are the primary information source, highlighting the need for more in-depth education and reliance on evidence-based resources. Targeted interventions focused on these areas could enhance prescribing practices and patient safety.

Immune-related adverse effects: Recognition and initiation of appropriate treatment in cancer patients on immunotherapy.

Delayed or improper identification of immune-related adverse events (IRAEs) during cancer treatment can impact time to receive proper treatment. This study describes rates of IRAE recognition and appropriate treatment in adult patients with cancer at a community teaching hospital. This single-center, retrospective, cohort study evaluated rates of proper IRAE treatment in conjunction with National Comprehensive Cancer Network (NCCN) guidelines. Secondary outcomes included time from presentation to IRAE diagnosis and hospital readmissions/repeat emergency department (ED) visits following initial admission for IRAE. Retrospective chart review assessed IRAE presentation including common terminology criteria for adverse event (CTCAE) grading and treatment choices. Fifteen subjects included in this study contributed to 21 encounters with noted IRAE. Over half (52.4%) of the encounters received proper IRAE treatment (e.g. correct drug, dose, route, frequency, or therapy duration). Nearly 22% of total actionable components were improper, occurring more often in patients with colitis, pneumonitis, and hepatitis. Median time to IRAE diagnosis was approximately 3.5 days, with the longest being 24 days. There were eight all-cause rehospitalizations one year after initial IRAE presentation, with four directly IRAE-related. Most (75%) IRAE-related rehospitalizations occurred with colitis. Seven ED return visits were also noted. Many IRAEs were misdiagnosed and/or received improper treatment resulting in increased rehospitalization/return ED visit rates. The importance of medical oncology involvement (e.g. medical oncology consult at time of admission and/or notification of primary oncologist) in IRAE management in the hospital or ED was also stressed. Organizations may benefit from systematic improvements and staff education to improve patient outcomes and prevent readmissions.

Knowledge and attitudes toward anaphylaxis to local anesthetics in dental practice

Objective/aimThe absence of a comprehensive understanding of potential anaphylactic reactions to local anesthetics (LAs) and management can result in grave consequences. For this reason we aim to assess Latin American dentists’ knowledge, preparedness, and competency in managing anaphylactic reactions to LAs.Materials and MethodsDesign: A cross-sectional study was conducted from November 2021 to February 2022. Board-certified dentists answered a survey comprising 26 structured questions. Chi-square tests and logistic regression models were performed in Stata 17.0. Setting: Argentina, Brazil, Colombia, Costa Rica, Ecuador, Honduras, Mexico, Peru, Venezuela, and other Latin American countries.ResultsOf 507 respondents, lidocaine was the most frequently used LA (88.1%). While 85.2% could identify dyspnea as a symptom of anaphylaxis, only 50.1% knew the correct route for epinephrine administration, and just 43.5% had epinephrine in their emergency kits. Confidence in managing anaphylactic reactions was low (9.6%). Older age was inversely related to both knowledge of anaphylaxis management and the possession of epinephrine (P = 0.003 and P = 0.0001, respectively).DiscussionOur study highlights a concerning discrepancy between the practical readiness of Latin American dentists in handling anaphylaxis.ConclusionThe study’s findings underscore the need for educational interventions to improve the readiness to identify and handle anaphylactic emergencies in dental practice.

A cross-sectional study on knowledge of epidemiological determinants, prevention and management of rabies among MBBS interns of a tertiary health care center of central India

Background: According to World Health Organization (WHO), rabies is a vaccine-preventable, zoonotic, viral disease caused by Lyssavirus type 1. It causes 20,000 deaths annually in India. MBBS interns represent the physicians who will graduate and practice medicine from next year. Hence, keeping this in mind, the present study was carried out to assess the knowledge regarding epidemiological determinants, prevention and management of rabies among MBBS interns. Methods: A cross-sectional study was conducted between April 2023 to June 2023 among 200 MBBS interns of Indira Gandhi Government Medical College, Nagpur, Maharashtra. Data was collected by the self-administered, pre-designed, pre-structured questionnaire and was analysed using statistical package for the social sciences (SPSS) software version 25. Results: It was seen that the mean age of participants was 23.34 (±0.859) years. The majority of participants were males (51.5%). The majority (80%) of interns knew the correct causative agent of rabies, while only 40% knew the correct incubation period of rabies. The majority, that is 63.5%, 85.5% and 75% of interns, knew the correct route, site and schedule of post exposure prophylaxis (PEP) respectively. Only 26.5% interns knew the correct management of category I animal bites, while 74.5% and 89% knew the correct management of category II and category III animal bites, respectively. The mean total knowledge score among interns was 13.17±2.63. Conclusions: The study found that interns with experience in dealing with animal bite cases had significantly higher total knowledge scores. To improve knowledge, interactive animal bite case-dealing sessions and regular CMEs should be conducted.

Bee Venom: Composition and Anticancer Properties.

Among the various natural compounds used in alternative and Oriental medicine, toxins isolated from different organisms have had their application for many years, and Apis mellifera venom has been studied the most extensively. Numerous studies dealing with the positive assets of bee venom (BV) indicated its beneficial properties. The usage of bee products to prevent the occurrence of diseases and for their treatment is often referred to as apitherapy and is based mainly on the experience of the traditional system of medical practice in diverse ethnic communities. Today, a large number of studies are focused on the antitumor effects of BV, which are mainly attributed to its basic polypeptide melittin (MEL). Previous studies have indicated that BV and its major constituent MEL cause a strong toxic effect on different cancer cells, such as liver, lung, bladder, kidney, prostate, breast, and leukemia cells, while a less pronounced effect was observed in normal non-target cells. Their proposed mechanisms of action, such as the effect on proliferation and growth inhibition, cell cycle alterations, and induction of cell death through several cancer cell death mechanisms, are associated with the activation of phospholipase A2 (PLA2), caspases, and matrix metalloproteinases that destroy cancer cells. Numerous cellular effects of BV and MEL need to be elucidated on the molecular level, while the key issue has to do with the trigger of the apoptotic cascade. Apoptosis could be either a consequence of the plasmatic membrane fenestration or the result of the direct interaction of the BV components with pro-apoptotic and anti-apoptotic factors. The interaction of BV peptides and enzymes with the plasma membrane is a crucial step in the whole process. However, before its possible application as a remedy, it is crucial to identify the correct route of exposure and dosage of BV and MEL for potential therapeutic use as well as potential side effects on normal cells and tissues to avoid any possible adverse event.

How Intuitive Is the Administration of Pediatric Emergency Medication Devices for Parents? Objective Observation and Subjective Self-Assessment.

to assess the intuitiveness of parents' administration of pediatric emergency devices (inhalation, rectal, buccal, nasal, and auto-injector). We invited parents without prior experience to administer the five devices to dummy dolls. We observed whether the parents chose the correct administration route and subsequently performed the correct administration procedures without clinically relevant errors. We interviewed parents for their self-assessment of their own administration performance and willingness to administer devices in actual emergencies. The correct administration route was best for the inhalation device (81/84, 96% of parents) and worst for the intranasal device (25/126, 20%). The correct administration procedures were best for the buccal device (63/98, 64%) and worst for the auto-injector device (0/93, 0%). Their own administration performance was rated to be best by parents for the inhalation device (59/84, 70%) and worst for the auto-injector device (17/93, 18%). The self-assessment of the correct administration overestimated the correct administration procedures for all the devices except the buccal one. Most parents were willing to administer the inhalation device in an emergency (67/94, 79%), while the fewest were willing to administration procedures the auto-injector device (28/93, 30%). Intuitiveness concerning the correct administration route and the subsequent correct administration procedures have to be improved for all the devices examined. The parents mostly overestimated their performance. Willingness to use a device in an actual emergency depended on the device.

Pharmacist Role in Medication Safety in a Busy Public Sector Pediatric Emergency, Pakistan

INTRODUCTION: Medication safety is very crucial part of patient safety as emergency department of any hospital is the busiest place of hospital where the possibility and likelihood of errors are much higher than any other part of the hospital. Human factor inherently limits the safety of health care process and contribute to medication errors. Recently, medication error has justly received significant attention, as it causes mortality, morbidity and additional healthcare costs, for example wrong dose prescribed and wrong dose administered for a prescribed medication.so despite the improved technology in the health care setting errors related to medication use continue to occur. The pharmacist plays a crucial role to oversee the quality of the entire drug distribution chain, from prescribing, drug choice, dispensing and preparation to the administration of drugs, and can fulfil a vital role in improving medication safety. OBJECTIVE: The aim of this study is to find out frequency of different types of prescription error in pediatric emergency to improve mediation as well as patient safety. METHOD: We conducted a retrospective study over a period of 6 months (from January 2023 to June 2023). The data were taken from electronic medical record (EMR) of all patients visiting in one of the pediatric emergency departments supported by child life foundation, who were prescribed intravenous medication were enrolled in the study. These prescriptions were checked by qualified pharmacist for correct dose, route, and timing of the drug. RESULTS: Total of 30,954 patient visited during the study period. 25,931 patients were prescribed intravenous medication. total of 784(3%) prescription errors were picked up. out of which 568 (68%) were due to wrong dose calculation and 76 (10%) patients were prescribed wrong medicine. 63(8%) patient were prescribed wrong units and 46(6%) each for wrong frequency and incomplete prescription. CONCLUSION: Unsafe medication practices leading to medication errors are the main causes of mortality and morbidity that can be prevented by a well trained and a qualified pharmacy department in ED of any hospital. the quality and safety of patient can be improved by preventing common medication error due to heavy flow of patient throughout the day.

Level of Awareness of Certified Non-critical Care Physicians in Diagnosing, Managing, and Disposing Anaphylactic Cases.

Anaphylaxis is known as an acute, severe hypersensitivity reaction that rapidly initiates after exposure to a triggering agent. It is a life-threatening condition, and early recognition and swift intervention are crucial to saving patients' lives. Objective: The objective of this study is to assess the ability of certified non-critical care physicians to recognize, manage, and dispose cases of anaphylaxis. A survey consisting of 19 questions was developed by expert emergency consultants to evaluate physicians' knowledge regarding the recognition, management, and disposition of anaphylactic episodes. Responses were collected through in-person surveys conducted with physicians from various specialties and varying clinical experience levels at a tertiary care center in the Eastern Province of Saudi Arabia. In this cross-sectional study, a total of 173 physicians completed the survey, with 81.5% being consultants and 18.5% specialists. Only 5.2% correctly identified all three proposed anaphylaxis clinical scenarios, 16.8% identified two scenarios correctly, and 51.4% identified only one scenario. While 42.8% recognized the first-line management of anaphylaxis, only 24.3% and 24.9% knew the correct epinephrine dose and route, respectively. Regarding the disposition of patients experiencing an anaphylactic episode, 61.9% of responders opted to dispose the case to the emergency department. Our study reveals a knowledge gap among non-critical care physicians practicing in a tertiary care center concerning the identification and management of anaphylaxis. Raising awareness of this life-threatening condition is imperative to address this serious issue.

Онлайн-обучение врачей неонкологических специальностей по профилактике и ранней диагностике злокачественных новообразований кожи.

One of the reasons for the late diagnosis of malignant skin neoplasms (hereinafter referred to as MNS) is the insufficient knowledge of doctors in non-oncology specialties [1], [2]. The sensitivity for recognizing cutaneous melanoma (hereinafter referred to as MNS) during a visual examination by primary care physicians is 40,2% [3]. The sensitivity of recognizing MNS for an inexperienced dermatologist is 69%, compared to the sensitivity of diagnosing MNS by an experienced dermatologist is 92% [4]. Also, the reason for the late diagnosis of MNS is an insufficiently complete examination of patients. Evidence suggests that doctors do not routinely offer full body mole screening. Up to 63% of patients diagnosed with MK visited their GP in the year before diagnosis. Only 30% of dermatologists perform a full body skin examination on all of their patients [5]. Thus, an important method is the education of doctors of non-oncology specialties in the form of training programs in the principles of early diagnosis of cancer, which in turn can help improve the oncological epidemiological situation [9]. The purpose of this study is to study the effectiveness of organizing an 8-hour online training aimed at raising the awareness of nononcology doctors on the prevention and early diagnosis of cancer. Material and methods. An 8-hour online course «Early diagnosis of skin tumors» was conducted for doctors, created by a group of authors on the platform «Personal Account of a Doctor at the Volga Research Medical University.» The training course included the following issues: risk factors for MK and other cancers, a description of the diagnostic algorithm using the ABCDE method with an illustration of each sign on photographic images, differential diagnosis of skin tumors, prevention with an emphasis on protection from ultraviolet radiation. The course used 82 photographs of MNS. The illustrated material consisted of 30 images of MK, 25 images of basal cell skin cancer (BCSC), 15 images of seborrheic keratoma of the skin, 12 images of skin hemangiomas. Conclusion. As a result of online training, one can note an improvement in the level of knowledge of doctors after completing an online course aimed at the prevention and early diagnosis of cervical cancer. Increasing the specificity of diagnosing nevi (0,846, 0,953) before and after, respectively, can help reduce costs in the “secondary level” of healthcare. The topic of prevention presented in the course also contributes to conducting preventive conversations with patients and correct patient routing. Thus, conducting online training has a number of advantages and shows good learning results. The diagnostic methods discussed in the course, aimed at clarifying the diagnosis of cancer, especially in the early stages of the disease, predetermine the choice of optimal treatment tactics and are the key to ensuring the best prognosis of the disease.

A review of map-matching algorithms

The public transport system is a key factor for the development of cities and for the satisfaction of citizens. For this reason, public transport management systems based on IT solutions were created. One of the problems that arise in public transport planning is tracking vehicle routes when using GPS information with signal interruptions or erroneous data. In these cases, it is necessary to implement some map-matching algorithms to solve these problems and follow the correct route for good information of the citizens waiting in the stations and for tracking the routes. This work aims to present the main map-matching algorithms and compare them, highlighting their utility and efficiency.

Resilient control strategy and attack detection on platooning of smart vehicles under DoS attack

Intent on the smart vehicles of a platoon to follow their correct routes, they must exchange their state information with each other based on a communication graph. Meanwhile, malicious factors like Denial-of-Service (DoS) attacks, one of the major types of cyber-attacks, can affect vehicles and divert them from their correct routes. Also, spreading the erroneous data induced by a DoS attack from the attacked agent gradually destabilizes the platoon. Therefore, preserving all vehicles’ safety is a vital issue for the platoon. In this paper, in the first step, detection and measurement of the DoS attack modeled by a time-varying delay are conducted by exploiting two incremental counters through a DoS detection and measurement algorithm. Also, supplementary to this, a novel vehicular resilient control strategy based on switching systems is proposed to retrieve the attacked agent to the leader–follower consensus. In the end, the capability of the proposed algorithms will be indicated by presenting an illustrative case study.
