Emergency Care for High-Altitude Trekking and Climbing.

Introduction: High altitude regions are characterized by harsh conditions (environmental, rough terrain, natural hazards, and limited hygiene and health care), which all may contribute to the risk of accidents/emergencies when trekking or climbing. Exposure to hypoxia, cold, wind, and solar radiation are typical features of the high altitude environment. Emergencies in these remote areas place high demands on the diagnostic and treatment skills of doctors and first-aiders. The aim of this review is to give insights on providing the best possible care for victims of emergencies at high altitude. Methods: Authors provide clinical recommendations based on their real-world experience, complemented by appropriate recent studies and internationally reputable guidelines. Results and Discussion: This review covers most of the emergencies/health issues that can occur when trekking or during high altitude climbing, that is, high altitude illnesses and hypothermia, freezing cold injuries, accidents, for example, with severe injuries due to falling, cardiovascular and respiratory illnesses, abdominal, musculoskeletal, eye, dental, and skin issues. We give a summary of current recommendations for emergency care and pain relief in case of these various incidents.

Epistaxis first-aid: a multi-center knowledge assessment study among medical workers.

PURPOSE: To assess the knowledge and confidence level regarding the basic first-aid for treating epistaxis among medical staff, including nurses and physicians across various medical disciplines. The study focused three aspects of first aid management: location of digital pressure, head position and duration of pressure. METHODS: The study involved 597 participants, categorized into five groups according to their specialties: emergency medicine, internal medicine, surgery, pediatrics, and community-based healthcare. A paper-based multiple-choice questionnaire assessed knowledge of managing epistaxis. Correct answers were determined from literature review and expert consensus. RESULTS: Most medical staff showed poor knowledge regarding the preferred site for applying digital pressure in epistaxis management. For head position, pediatricians and internal medicine physicians were most accurate (79.4% and 64.8%, respectively, p < 0.01), and nurses from the emergency department outperformed nurses from other disciplines; internal medicine, surgery, pediatrics, and community-based healthcare (61.1%, 41.5%, 43.5%, 60%, 45.6%, respectively, p < 0.05). While most medical staff were unfamiliar with the recommended duration for applying pressure on the nose, pediatricians and community clinic physicians were most accurate (47.1% and 46.0%, respectively, p < 0.01), while ER physicians were least accurate (14.9%, p < 0.01). Interestingly, a negative correlation was found between years of work experience and reported confidence level in managing epistaxis. CONCLUSIONS: Our findings indicate a significant lack of knowledge concerning epistaxis first-aid among medical staff, particularly physicians in emergency departments. This finding highlights the pressing need for education and training to enhance healthcare workers' knowledge in managing epistaxis.

The effect of psychological first-aid virtual education on the communication skills of nurses in disasters: a randomized controlled trial.

BACKGROUND: Disasters have affected the physical and mental health of people around the world. Since nurses are frontlines in disasters, it seems necessary to prepare for this responsibility. This study investigates the effect of psychological first-aid virtual education on the communication skills of nurses in disasters such as COVID pandemic. METHODS: In a randomized controlled trial, 55 nurses were selected by purposive sampling method from two hospitals in Isfahan and Tehran, Iran in December-November 2022 and randomly replaced in the intervention group who participated in psychological first aid virtual training and control group. The data were collected through the personal information form and Communication Skills -Test-Revised (CSTR). RESULTS: Two groups were homogeneous in terms of communication skills (p = 0.177), the total score of communication skills was significant between the two groups after the intervention (p < 0.0001). Regarding communication skills, in the pre-intervention phase, the subscale of "the ability to receive and send messages" and "insight into the communication process" the difference before the intervention was not significant between the two groups (p > 0.05). However, it was significant between the two groups after the intervention (p < 0.05), and regarding "emotional control", "listening skills", and "communication along with assertiveness" the difference before and after the intervention was not significant between the two groups (p > 0.05). CONCLUSION: Pre-disaster training and virtual education can increase nurses' communication skills in their ability to handle a disaster such as COVID pandemic. Virtual education of post-disaster psychological interventions is suggested.

Assessment of knowledge towards first aid skills of epilepsy among undergraduate health students in Riyadh province of Saudi Arabia: A cross-sectional study.

BACKGROUND: Applying proper first-aid measures to patients with seizure episodes plays a vital role in preventing the adverse consequences of seizures. Most previous data focused on teachers, healthcare providers and the general public. This study aimed to assess the knowledge of seizure first-aid measures among undergraduate health students. METHODS: This descriptive, cross-sectional study was conducted between May 16 and 31, 2023, with 493 undergraduate health students of Riyadh Province who answered online surveys. The data were collected using the descriptive information form. The chi-square (χ2) test was employed to compare knowledge of seizure first aid between demographic variables. The relationship between knowledge score and independent variables was evaluated using multiple linear regression technique. RESULTS: Only 1.6 % of participants demonstrated good knowledge scores toward seizure first-aid measures. The skill most frequently reported was to remove all harmful objects from their vicinity and loosen the tight clothes around the neck during a seizure; 68.7 % of the participants correctly answered with agreed. Conversely, the skill that received the lowest knowledge score among participants was putting a piece object such as a cloth, wallet, or spoon between the teeth to prevent tongue biting during a seizure; only 37.3 % of the participants correctly answered with disagree. Moreover, participants in the advanced age group, medicine and fifth-year, were found to be significant predictors of knowledge and exhibited better knowledge scores toward seizure first aid measures than their peers (p < 0.001). Furthermore, lectures and books were identified (69.6 %) as the most common source of information about seizure first aid. CONCLUSION: The study concluded that most undergraduate health students demonstrated poor knowledge scores in delivering seizure first aid. This finding suggests that introducing epilepsy education from the first year in all health-related courses is crucial to improving overall awareness and skills in providing seizure first aid.

Bridging the first-aid knowledge gap: a cross-sectional study of medical scope students in Syria.

INTRODUCTION AND OBJECTIVE: Sufficient knowledge required to deal with emergencies at the accident site may not be found in most medical students due to the lack of effective first-aid training in most medical education curricula. This study aims to assess and evaluate medical students' knowledge level in providing first-aid care, especially first-year students. METHODS: An electronic questionnaire was distributed via social media to 1,855 medical students in October 2020. The knowledge level was assessed based on scores obtained for each clinical scenario requiring first aid and classified as good, intermediate, or weak. Statistical analysis was performed using SPSS software. RESULTS: The study found that academic year and specialization significantly influence medical students' first-aid knowledge level. However, demographic factors such as gender, university, marital status, housing status, work status, financial condition, and previous first-aid training did not show any significant effect. CONCLUSION: The level of knowledge among Syrian medical students in providing first-aid care is somewhat limited. Therefore, first-aid courses should be made more accessible to these students, and their effectiveness should be ensured and maintained through frequent updates. Moreover, more attention should be placed on publicizing first-aid knowledge to make life-saving procedures attainable to anyone, anytime and anywhere.

Awareness, attitudes and first aid knowledge of epilepsy among university students - A cross-sectional study in Henan Province, China.

PURPOSE: Epilepsy is a debilitating disease that can lead to series of social and psychological issues, impairing the quality of life of people with epilepsy (PWE). This survey aimed to investigate the awareness, attitudes, and first-aid knowledge of epilepsy in university students METHOD: This cross-sectional study was conducted in Henan Province, China between January 1 and April 30, 2022. Students majored in education, medicine, science and engineering from 8 universities attended the study. The survey questionnaire comprised 28 questions covering 4 sections: demographic characteristics, awareness of epilepsy, attitudes toward PWE and knowledge of first aid for seizures. RESULTS: A total of 2376 university students completed the questionnaire. 94.7% heard of epilepsy. In the first aid knowledge section, individual question was correctly answered by at least 50% students, 9.3% students correctly answered all questions. Attitude toward PWE was independently (R2 =0.108, F=73.227, p < 0.001) associated with both awareness of epilepsy (B=0.411, p < 0.001) and first aid knowledge of epilepsy (B=0.047, p = 0.001). Among the three majors, medical students had more positive attitudes toward PWE than students majored in education, science and engineering (p < 0.05). However, medical students performed worse among the groups when answering the first aid knowledge questions. CONCLUSION: This survey showed that university students in Central China had a good awareness of epilepsy. For medical students, improvements are necessary for the awareness of the first aid knowledge for seizure.

Knowledge and management of traumatic dental injuries among schoolteachers in Hungary: a cross-sectional study with educational intervention.

PURPOSE: This study aimed to evaluate the knowledge of Hungarian schoolteachers in the management of dental trauma injuries (TDI) of children between the ages of 3 and 18 and to illustrate a brief educational intervention on TDI management. METHODS: A 15-item questionnaire on dental injuries was distributed in our observational cross-sectional study to 2720 Hungarian educational institutions to explore and evaluate teachers' knowledge in January 2019. Two years later, targeted information material was made accessible regarding TDI management. In the second post-intervention phase of the study, educator knowledge was re-evaluated using the same questionnaire. Statistical analysis (Mann-Whitney and Chi-square tests) was performed using IBM SPSS Statistics 28. RESULTS: A total of 1426 answers were collected in the initial survey. Although more than half (51.9%) of the respondents previously witnessed TDIs, 86.5% still did not perceive themselves as adequately informed regarding TDI management. Most teachers submitted appropriate responses to the indicator questions relating to the urgency of referral to dental professionals (71.8%), immediate contact with parents (79.0%) or dentists (13.0%), and the solution for avulsed teeth (81.3%). However, only every second (56.2%) educator responded correctly regarding the proper cleaning method. Following accessibility to our educational material, 622 respondents completed the post-intervention questionnaire in the second phase of the study. The percentage of appropriate responses to the five indicator questions significantly increased by 5-20.6%. CONCLUSION: Teachers' knowledge of TDI was inadequate yet can improve with online education. Efforts among dental professionals, the media, and targeted interventions will ensure adequate knowledge while also improving children's dental health.

A Cellulose/Chitosan Dual Cross-Linked Multifunctional and Resilient Hydrogel for Emergent Open Wound Management.

Adhesive hydrogel holds huge potential in biomedical applications, such as hemostasis and emergent wound management during outpatient treatment or surgery. However, most adhesive hydrogels underperform to offer robust adhesions on the wet tissue, increasing the risk of hemorrhage and reducing the fault tolerance of surgery. To address this issue, this work develops a polysaccharide-based bioadhesive hydrogel tape (ACAN) consisting of dual cross-linking of allyl cellulose (AC) and carboxymethyl chitosan (CMCS). The hygroscopicity of AC and CMCS networks enables ACAN to remove interfacial water from the tissue surface and initializes a physical cross-link instantly. Subsequently, covalent cross-links are developed with amine moieties to sustain long-term and robust adhesion. The dual cross-linked ACAN also has good cytocompatibility with controllable mechanical properties matching to the tissue, where the addition of CMCS provides remarkable antibacterial properties and hemostatic capability. Moreover, compared with commercially available 3 M film, ACAN provides an ultrafast wound healing on tissue. The ACAN hybrid hydrogels have advantages such as biocompatibility and antibacterial, hemostatic, and wound healing properties, shedding new light on first-aid tape design and advancing the cellulose-based materials technology for high-performance biomedical applications.

Comparative study on clinical characteristics of cardiogenic and non-cardiogenic cardiac arrest patients out-of-hospital based on Utstein style / 中华急诊医学杂志

Objective:To analyze the causes of out-of-hospital cardiac arrest (OHCA) and the differences in outcomes of pre-hospital first-aid measures and cardiopulmonary resuscitation for different etiologies, improved the success rate of rescue.Methods:A retrospective study was conducted on OHCA patients admitted to Beijing Emergency Medical Centre from January to December 2021. The pre-hospital emergency medical records and rescue results within medical institutions were collected. Compared the basic situation between patients with cardiogenic and non-cardiogenic cardiac arrest, the differences of rescue measures and CPR outcomes between the groups were compared by non-parametric test and χ 2 test. Results:A total of 7 517 patients were included in this study. Cardiogenic arrest patients were older, more underlying diseases (84.2%), and cardiac arrest mainly occurred at home. The cause of non-cardiogenic arrest included disease (85.1%), trauma (2.9%), suicide (5.0%), traffic accidents (1.7%), poisoning (1.1%), and so on. In terms of first-aid measures, after the emergency doctor arrived at the scene, the proportion of first-aid measures used for cardiogenic patients was high (22.3%), and the first aid measures include cardiopulmonary resuscitation, tracheal intubation, defibrillation, oxygen inhalation, injection of adrenaline and use of other drugs. All the proportions of first-aid measures for cardiogenic patients were significantly higher than non-cardiogenic patients (all P<0.001). In terms of clinical outcomes, there were no statistical differences in return of spontaneous circulation ( P=0.072) and 24-hour survival ( P=0.093) between cardiogenic and non-cardiogenic patients. Conclusions:Cardiogenic cardiac arrest was the main cause of OHCA. Cardiogenic arrest patients were more underlying diseases, and older in age, the main clinical feature was onset at home. The comprehensive treatment measures for pre-hospital first-aid cardiac arrest should continue to be strengthened to improve the success rate of rescue for OHCA.

Awareness of Seizure First Aid among the population in Jazan, Saudi Arabia: A survey Study.

Background: First aid during a seizure is critical, but many people in Jazan, Saudi Arabia may not know what to do. This is because epilepsy is often stigmatized in the region and regarded as a spiritual or mental disorder. This study investigated the awareness of seizure first aid among the population living in Jazan. Methods: An online survey was conducted. Healthcare workers and people who had never heard of epilepsy were excluded. Participants were asked to identify correct measures of seizure first aid from a list of 20 statements [9 correct and 11 incorrect]. A composite awareness score was calculated by subtracting the number of incorrect statements from the number of correct statements. Participants were classified into three groups: high, intermediate, and low awareness. Logistic regression was used to identify factors associated with high awareness. Results: Of the 1215 participants, 80.5 % had low awareness of seizure first aid. The most common correct responses were clearing the area of dangerous objects (91.3 %), putting a pillow under the neck (69.3 %), and timing the seizure (68.5 %). However, only 32.2 % knew to tell the person what happened after the seizure. The most common misconception was that an ambulance should be called immediately, regardless of the details (88.3 %). Other common misconceptions included putting something in the person's mouth (87.5 %), holding them down (83.0 %), taking out their contact lenses (79.9 %), and giving antiseizure medications orally (73.2 %). People who previously watched an educational video on seizure first aid (OR = 4.27, 95 % CI = 1.48-12.34, p = .007) or who knew someone with epilepsy (OR = 9.01, 95 % CI = 2.82-28.83, p < .001) were more likely to have a high awareness of seizure first aid. Conclusion: The study found that most people in Jazan, Saudi Arabia do not know how to provide first aid for seizures. The findings inform future research and highlight the need for increased education and training on seizure first aid in this region.

Awareness of First Aid Management of Epistaxis in Children Among Parents in Arar, Saudi Arabia.

BACKGROUND: Epistaxis is a relatively common condition, particularly among children, necessitating that parents be well informed about its effective management. OBJECTIVES: This study aims to explore the current level of awareness among parents in the Arar region, Saudi Arabia, regarding the first aid management of epistaxis and to highlight the importance of education in empowering parents to handle such situations. METHODS: A cross-sectional study was conducted using a survey distributed among the Arar population (aged >18 years) who had at least one child and were willing to participate. Data were collected between mid-July and the end of September 2023 using a self-administered questionnaire, which included a consent form, sociodemographic and background items, and epistaxis knowledge-related questions. RESULTS: A total of 342 participants (27.8% males) completed the questionnaire. It was observed that 47.4% of the participants' children had experienced epistaxis. Only around half of them (n=84; 51.9%) had received first aid management for epistaxis, and only 40.4% of the parents correctly identified all the necessary steps for managing it through first aid. There was inadequate knowledge regarding the causes/risk factors and appropriate first aid techniques for epistaxis. Certain sociodemographic factors were significantly associated with better knowledge of first aid management of epistaxis, such as female gender (p = 0.003), older participants (p = 0.002), and a higher educational level (p = 0.001). CONCLUSION: The study found low awareness of first aid management of epistaxis among parents residing in Arar, Saudi Arabia. Factors related to the demographic characteristics of the study participants were associated with this level of knowledge. These findings emphasize the need to improve awareness about first aid management of epistaxis, particularly among younger individuals, males, and those with limited education. Effective interventions should be developed to enhance first aid training, considering the specific risk factors associated with epistaxis.

Assessment of Public Knowledge and Awareness on First-Aid Management of Epistaxis in Makkah, Saudi Arabia.

BACKGROUND: Epistaxis is a common medical problem requiring first aid. However, public awareness of proper first-aid techniques for epistaxis is limited. This study assessed the knowledge and attitudes toward first-aid epistaxis management among the general population in the Makkah region. METHODS: A cross-sectional online survey was conducted with 1,259 participants from various regions in Makkah. The survey assessed participants' epidemiological information, experience with epistaxis, and knowledge of proper first-aid techniques. The knowledge scores were calculated and categorized as either good or poor. Associations between the variables and predictors of good knowledge were analyzed. RESULT: Overall knowledge of proper epistaxis first aid was poor, with only 467 (37.1%) demonstrating good knowledge. Women, healthcare workers, and those with prior epistaxis showed higher odds of having good knowledge than their counterparts. Relatives/friends and social media were cited as the main knowledge sources, rather than healthcare providers. CONCLUSION: Public awareness of appropriate first-aid epistaxis techniques in Makkah is inadequate. Targeted educational interventions involving healthcare providers are needed to improve the first-aid management of this common medical issue.

[The nontrivial approach or how physicians-bolsheviks treated kings. The Soviet medicine in the Arabian peninsula in 1920-1930s].

In the late 1920s, the USSR intensified its international activities in the Arabian Peninsula. The rapprochement with Arab monarchies provided opportunity to study political, economic and ethno-cultural characteristics of region by organizing transit of pilgrims to Mecca through the Soviet territory and providing medical care in first-aid posts at diplomatic missions. The Soviet physicians, in atypical situation of Arab monarchies, played important role as intermediaries between royal courts and the Soviet government, serving as agents of "soft power". The article considers causes of Moscow geopolitical interest to this region in 1920s-1930s. The distinctions of interaction between Soviet physicians and ruling circles of Hijaz and Yemen were explored. The humanitarian, cultural and geopolitical significance of these activities were examined. The article considers and explains, through optics of geopolitical approach, situational rationality that was applied by medical men when approaching treatment of royal personages despite ideological mismatch of this work with Bolshevism dogmas. The article consistently demonstrates, noting non-triviality of both locus itself and approaches to organization of medical care, how professionalism of Soviet physicians gained confidence of monarchs of Hijaz and Yemen in complicated conditions of competition with highly qualified physicians from Western Europe. It is emphasized that in conditions of Arabia, ideological attitudes had secondary importance, while such qualities as personal charisma and medical professionalism, which created solid reputation foundation for Soviet physicians, came to foreground.

Knowledge, awareness, and attitudes towards epilepsy among elementary schoolteachers in the Kingdom of Bahrain.

BACKGROUND: Teachers' awareness of epilepsy and attitudes toward students with epilepsy (SWE) largely affect their health, behavior, and academic performance. This study aimed to assess elementary schoolteachers' background knowledge and attitudes toward epilepsy in the Kingdom of Bahrain. METHODS: A 23-item online questionnaire was distributed to elementary school teachers in all public schools in Bahrain between September 2022 and February 2023. The questionnaire included three sets of questions about teachers'1) demographics and teaching experience, 2) knowledge and experience with epilepsy, and 3) attitude towards SWE. RESULTS: Three hundred and sixty-seven teachers responded to the questionnaire. Only 82 participants (22.3%) thought they had enough information about epilepsy. Approximately 25% had previously taught SWE. Even though 9.3% have witnessed a seizure before, only 2.2% received seizure first aid training courses. Most respondents (68.7%) knew that epilepsy is caused by abnormal brain electrical activity and is not contagious (95.1%). Regarding seizure types, 76.6% were aware of uncontrollable jerky movements, while staring spells were recognized by 45%. Most first-aid responses were inappropriate, as 59.7% would open the patient's mouth. Only 39.5% agreed on patient transfer to the hospital if the seizure lasted ≥5 min. Epilepsy was thought to cause mental retardation by 32.4%. Also, the belief that SWE were more prone to bullying was reported by 57.2%. CONCLUSION: The knowledge and attitudes of schoolteachers in Bahrain towards epilepsy are relatively good but with remaining improvement potential. They do not fully grasp all seizure types nor adequate first-aid measures promoting future epilepsy educational programs.

Parents' knowledge regarding first-aid management of epistaxis in children in Taif, Saudi Arabia.

Objectives: Epistaxis among children is considered a scary issue for both the child and the parents. In Saudi Arabia, one third of children suffer from epistaxis. In our study, we aimed to assess the level of knowledge among parents regarding first-aid management of epistaxis in Taif city, Saudi Arabia. Method: We carried out a descriptive cross-sectional study among parents who visited Alhada Armed Forces Hospital and Prince Mansour Military Hospital between May 2022 and July 2022 in Taif, Saudi Arabia. A questionnaire with 17 questions was distributed among the participants. We excluded parents with children who were older than 18 years. Results: A total of 502 parents were included in the study. About two thirds (67.5%) of parents had a moderate level of knowledge and around one third (30.9%) showed a good level of knowledge regarding epistaxis first aid. Furthermore, higher knowledge scores were found among parents who had epistaxis previously (P = 0.026), who attended a course on first aid (P = 0.002), and who were aged more than 35 years (P = 0.017). Conclusion: Our study demonstrated that most Saudi parents had a moderate level of knowledge regarding first-aid management of epistaxis. Additionally, several factors, such as the number of children, age, those attending first-aid courses, and experience treating others with epistaxis, were associated with the level of knowledge among parents. Further larger studies are required among Saudi parents to examine the knowledge, practice, and related factors regarding first-aid management of epistaxis.

First-Aid Hydrogel Wound Dressing with Reliable Hemostatic and Antibacterial Capability for Traumatic Injuries.

First-aid for severe traumatic injuries in the battlefield or pre-hospital environment, especially for skin defects or visceral rupture, remains a substantial medical challenge even in the context of the rapidly evolving modern medical technology. Hydrogel-based biomaterials are highly anticipated for excellent biocompatibility and bio-functional designability. Yet, inadequate mechanical and bio-adhesion properties limit their clinical application. To address these challenges, a kind of multifunctional hydrogel wound dressing is developed with the collective multi-crosslinking advantages of dynamic covalent bonds, metal-catechol chelation, and hydrogen bonds. The mussel-inspired design and zinc oxide-enhanced cohesion strategy collaboratively reinforce the hydrogel's bio-adhesion in bloody or humoral environments. The pH-sensitive coordinate Zn2+ -catechol bond and dynamic Schiff base with reversible breakage and reformation equip the hydrogel dressing with excellent self-healing and on-demand removal properties. In vivo evaluation in a rat ventricular perforation model and Methicillin-resistant Staphylococcus aureus (MRSA)-infected full-thickness skin defect model reveal excellent hemostatic, antibacterial and pro-healing effectiveness of the hydrogel dressing, demonstrating its great potential in dealing with severe bleeding and infected full-thickness skin wounds.

Contribution of the 5G Smart First-Aid Care Platform to Achieving High-Quality Prehospital Care.

China is gradually becoming an aging society, and the necessity for prehospital first-aid care is increasing. However, there is a long-term information blind spot in traditional prehospital first-aid care. Fifth-generation (5G) network has the advantages of enhanced broadband, multiple connections, and low latency. Combined with the current prehospital first-aid system, the 5G smart medical prehospital first-aid care model creates a new opportunity for the development of prehospital first-aid care. This paper aimed to describe the 5G smart first-aid care platform and offers practical insights into the construction and application of the 5G smart first-aid care platform in small- and medium-sized cities. We first introduced the working principle of the 5G smart first-aid care platform and then chose patients with prehospital chest pain as an example to describe the whole workflow in detail. The application of the 5G smart emergency-care platform is at the stage of pilot exploration in large- and medium-sized cities. Big data statistical analysis of the completed first-aid care tasks has not been performed yet. The 5G smart first-aid care platform realizes real-time interconnection of information between the ambulance and the hospital, performs remote consultation, shortens the treatment time, and enhances treatment efficiency. Future research should focus on quality control analysis of the 5G smart first-aid care platform.

Effectiveness of first-aid education in road traffic crashes on non-healthcare professionals' knowledge, attitude, and skills: a systematic review.

This review aimed to evaluate and synthesize information on the effects of first-aid education in road traffic crashes on knowledge, attitudes, and skills among non-healthcare professionals. A qualitative study was designed according to the Prepared Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) standards to evaluate three outcomes, knowledge, skills, and attitude. The search strategy was performed in five databases (Science Direct, Scopus, CINAHL Plus, PubMed, and Google Scholar) to retrieve primary studies published between January 2011 and December 2021. In addition, the full texts of randomized controlled trials conducted on adults were included. Among the 2,399 articles retrieved from the databases, 2,388 were discarded, and only five studies met the inclusion criteria and were used in the final analysis and synthesis. Three of the five studies suggested that knowledge and skills are crucial in differentiating outcome factors between intervention and control groups regarding the effectiveness of first aid education. However, two studies on attitude and behaviour toward first-aid found no discernible change between the intervention and the control group. Therefore, our review revealed that only a well-structured first aid education is crucial to leverage the knowledge and skills of non-healthcare professionals before first aid provision, not attitude or behaviours.

Immediate Medical Care Rendered by US Law Enforcement Officers after Officer-Involved Shootings - An Open-Access Public Domain Video Analysis.

BACKGROUND: After officer-involved shootings (OIS), rapid delivery of emergency medical care is critical but may be delayed due to scene safety concerns. The purpose of this study was to describe medical care rendered by law enforcement officers (LEOs) after lethal force incidents. METHODS: Retrospective analysis of open-source video footage of OIS occurring from February 15, 2013 through December 31, 2020. Frequency and nature of care provided, time until LEO and Emergency Medical Services (EMS) care, and mortality outcomes were evaluated. The study was deemed exempt by the Mayo Clinic Institutional Review Board. RESULTS: Three hundred forty-two (342) videos were included in the final analysis; LEOs rendered care in 172 (50.3%) incidents. Average elapsed time from time-of-injury (TOI) to LEO-provided care was 155.8 (SD = 198.8) seconds. Hemorrhage control was the most common intervention performed. An average of 214.2 seconds elapsed between LEO care and EMS arrival. No mortality difference was identified between LEO versus EMS care (P = .1631). Subjects with truncal wounds were more likely to die than those with extremity wounds (P < .00001). CONCLUSIONS: It was found that LEOs rendered medical care in one-half of all OIS incidents, initiating care on average 3.5 minutes prior to EMS arrival. Although no significant mortality difference was noted for LEO versus EMS care, this finding must be interpreted cautiously, as specific interventions, such as extremity hemorrhage control, may have impacted select patients. Future studies are needed to determine optimal LEO care for these patients.

Comparing Gastroesophageal Reflux Disease (GERD) and Non-GERD Patients Based on Knowledge Level of Acute Myocardial Infarction Symptoms, Risk Factors and Immediate Action Taken in Eastern Province, Saudi Arabia.

INTRODUCTION: A major cause of death globally is cardiovascular disease (CVD). Chest pain, nausea, vomiting, and heartburn are common symptoms of acute myocardial infarction (AMI). Chest pain is also the main symptom of gastroesophageal reflux disease (GERD). Therefore, the differential diagnosis of chest pain can become more challenging when GERD and AMI coincide. This study evaluated and compared the knowledge of the signs, symptoms, and immediate action that must be taken regarding AMI among GERD and non-GERD patients. METHODOLOGY: An observational cross-sectional study using an online questionnaire was created and published between October and November 2022 to collect data from Saudi males and females 18 or older willing to participate in the study. Participants who were not Saudi had declined to complete the survey or had not fully completed it was excluded. The questionnaire contained three sections; after collecting informed consent, it made inquiries regarding respondents' GERD status, demographic information, and knowledge and attitudes regarding GERD. RESULTS: This study included 691 responses from 300 non-GERD participants and 391 GERD participants. The study showed a high level of awareness (75.5%) of GERD, with significant differences in the level of awareness according to marital status, education levels, and occupation status. There was no significant difference in the level of awareness according to gender and GERD diagnosis, where the p-value > 0.05. The most common source of information about AMI was the Internet, followed by health care professionals. The most commonly known symptoms of AMI were sudden pain or discomfort in the chest, followed by a sudden shortness of breath. Additionally, there was no significant association between the diagnosis of GERD and known risk factors. The association between GERD and other diseases (chi-square = 46.94, p-value 0.01). Obesity and smoking were the two main risk factors for heart attacks. CONCLUSION: This study demonstrated that there was no significant difference between GERD and non-GERD participants regarding the knowledge and awareness level of AMI. Moreover, it showed that there was a lack of general knowledge and awareness of AMI in Saudi Arabia. The authors recommend initiating more awareness programs in Saudi Arabia to inform people about AMI and cardiovascular disease. More research is required to determine whether other patients are aware of AMI.
