In Saudi Arabia, the prevalence of BIs array from 112 to 518 per 100,000 per year. The appropriate awareness of performing first aid could facilitate to improve the outcomes of burns. Purpose and Objectives: To appraise the community that acknowledges burns, first aid, and associated factors among the community population in Jazan City, Saudi Arabia. The paper aims to identify limitations to encourage additional research and persuade legislators to develop improved burn-injury care recommendations and training programs. Materials and Methods: An observational-based sample survey was conducted among the people who live in Jazan City aging 13 years or more, during April 5 to May 5, 2023. Data collection was done by a validated online self-administrated questionnaire sent randomly to community members in different parts of Jazan City via social media platforms. Collected data were coded and cleaned by an excel program, and finally exported on SPSS 26.0 software. The variables were analyzed using descriptive statistics like frequencies and percentages. Also, the Chi-square test was used to investigate the relation between different variables, with a significance value of P Results: This study included 243 participants (about 62%) among them were mostly male participants (151) having a university degree. The majority of participants 75% did not take any form of BFA training in the past. This study shows that 69.9% of the participants have inadequate awareness, despite 72% having a constructive attitude towards burn first aid. Previous burn-related first aid training was significantly associated with participants’ knowledge of BFA at a p-value less than 0.05. Conclusion: This study indicates a high frequency of Jazan population having inadequate knowledge of burn first aid despite the high prevalence of a favorable attitude. There is a need to develop an effective nationwide burn prevention program and early burn first aid treatment in Saudi Arabia and promote a consistent guideline for burn first aid.展开更多

Many pieces of research have been published on the virus’s pattern and transmission routes, and a few studies have been published on its psychological repercussions for the general public and health care workers in particular. We aimed in this study to figure out the impact of COVID-19 pandemic on the mental health of health care workers in the Jazan region and compare it to non-health care workers. Results: There were 221 participants in this study conducted in the Jazan region KSA, during the first part of 2022. 117 participants were non-HCWs (Health Care Workers) and 104 participants were HCWs. 31.7% of HCWs had high score of PTSD symptoms which may suppress their immunity, PTSD was a clinical concern in 12.5%, 6.7% had probable PTSD, and 49% had no PTSD. The average PTSD score in HCWs was 26.14. In contrast, the great majority of non-HCWs (69.2%) had no PTSD;PTSD was a clinical concern in 16.2%, 11.1% had a score indicating PTSD had the potential for immunosuppression, and 3.4% had probable PTSD. Conclusion: The COVID-19 pandemic did not affect just those who were infected with the virus, nor was it restricted to the mental health of those afflicted;rather, the influence expanded until it reached the general public and, in particular, those who had contact with patients, such as health care workers. As a result, mental health investigation, follow-up, and therapy are required to preserve the mental health of health care workers as well as the general population.展开更多

Knowledge, attitudes, beliefs and perceived risk are cognitive factors that can affect patient’s decision to seek care immediately. Therefore, this study aimed to explore knowledge, attitudes, beliefs, and perceived risk for future ACS event among Jordanian ACS patients. Methods: A descriptive, cross-sectional, correlational design was used to conveniently recruit 160 ACS patients from CCUs and medical floors at three Jordanian hospitals using the Modified ACS Response Questionnaire. Results: Almost, 65% of participants had low level of ACS knowledge, specifically regarding untraditional ACS symptoms. Some negative attitudes and beliefs toward ACS were found. There was a moderate positive correlation between knowledge score and all of attitudes, beliefs and perceived risk score (r = 0.549, p Conclusion: Inadequate ACS knowledge, negative attitudes and beliefs toward ACS were associated with low perceived risk for future ACS event. Therefore, it is a priority to develop strategies that consider improving ACS patients’ knowledge, attitudes, beliefs and perceived risk. This could be effective to enhance patient’s decision to seek care and reduce ominous outcomes.展开更多

However, airbags have also been described as a source of injuries related to airbag deployment. Typical airbag-related injuries are eye injuries, cervical spine injuries, rib fractures, cardiac injuries, extremity injuries, and thoracic aortic rupture(TAR).[1-3] Approximately one-third of patients with TAR who survive till hospital admission die before surgical treatment.[4] We present a patient with TAR after a lowspeed motor vehicle accident with rapidly deteriorating vital signs and subsequent death on the scene.展开更多

These devices are comfortable and useful, they keep chest compression following the recommendations as they do not depend on interpersonal variability, they do not get tired, their use is simple and one of the rescuers is released from this task, thus facilitating the assistance. Besides, their use in transport conditions makes it safer. However, when coming to results, these mechanical CPR devices have not clearly demonstrated such an advantage, neither in the field of cardiac arrest, nor in organ preservation in the case of donors after cardiac death. In donors after cardiac death they are widely used by most of the emergency services involved, but a number of injuries produced in lungs during the early years of their use have made it controversial. In this paper we make a review of the road traveled by mechanical CPR devices and of the main articles which mark the way.展开更多

An exploratory descriptive design was utilized using the cross-sectional survey with self-reported questionnaires (Demographics, Charlson Comorbidity Index, Exercise Self-Efficacy Scale, Exercise Benefits and Barriers Scale, and Commitment to a Plan for Exercise Scale). A convenience sample of 115 Jordanians with diabetes mellitus was recruited from diabetes outpatient clinics. Participants reported an average number of 3.2 physical activities per week (average of 2.9 hours), with walking being the most common activity. Participant’s body mass index, comorbidity index, and exercise self-efficacy were correlated with both frequency and duration of exercise (r = -0.393, -0.286, 0.219 and -0.272, 0.383, 0.260, respectively). A predictive model of five predictors (age, BMI, CCI, exercise self efficacy, and perceived exercise barriers) that significantly predicted exercise duration (R<sup>2</sup> = 0.34, F = 9.14, P < 0.000) was found. Diabetic patients were found to exercise less than optimum. Illness itself was not a cause of not exercising compared to lack of time and desire. Factors that can enhance or inhibit participants’ engagement in exercise should be included in designing tailored exercise educational programs.展开更多

文摘BACKGROUND:To assess the efficacy of the epidemic prevention measures of the“closed-loop”system adopted by the Beijing 2022 Olympic Winter Games(BOWG).METHODS:We retrospectively collected and analyzed information,including age,sex,nationality,vaccination status,date of diagnosis,and date of entry,from 280 SARS-CoV-2-positive individuals identified during the BOWG.A susceptibility-exposed-infectious-remove model was employed to evaluate the effectiveness of epidemic prevention strategies on controlling the spread of SARS-CoV-2 under different scenarios during the BOWG.RESULTS:Regarding SARS-CoV-2-positive cases,97.9%were imported,and 96.4%were asymptomatic.The median age was 37 years(range:29–47 years),and 73.9%were male,with the majority of cases being broadcasters and European attendees.Regarding vaccination status,93.5%were fully vaccinated,and six cases were considered to have been infected in the closed-loop system during the BOWG.Assuming that the BOWG adopted a semi-closed-loop management system,the cumulative number of confirmed cases would be 1,137 for quick quarantine measures(3 d later)implemented and 5,530 for delayed quarantine measures(9 d later)implemented.This modeling revealed that stringent pandemic prevention measures and closed-loop management effectively controlled the spread of SARS-CoV-2 during the BOWG.CONCLUSION:Imported cases are considered the main risk factor for SARS-CoV-2 transmission during mass gatherings,but a comprehensive closed-loop system could minimize transmission among attendees and general personnel.
文摘Background: COVID-19 was declared a worldwide pandemic by the World Health Organization in 2020. Many pieces of research have been published on the virus’s pattern and transmission routes, and a few studies have been published on its psychological repercussions for the general public and health care workers in particular. We aimed in this study to figure out the impact of COVID-19 pandemic on the mental health of health care workers in the Jazan region and compare it to non-health care workers. Results: There were 221 participants in this study conducted in the Jazan region KSA, during the first part of 2022. 117 participants were non-HCWs (Health Care Workers) and 104 participants were HCWs. 31.7% of HCWs had high score of PTSD symptoms which may suppress their immunity, PTSD was a clinical concern in 12.5%, 6.7% had probable PTSD, and 49% had no PTSD. The average PTSD score in HCWs was 26.14. In contrast, the great majority of non-HCWs (69.2%) had no PTSD;PTSD was a clinical concern in 16.2%, 11.1% had a score indicating PTSD had the potential for immunosuppression, and 3.4% had probable PTSD. Conclusion: The COVID-19 pandemic did not affect just those who were infected with the virus, nor was it restricted to the mental health of those afflicted;rather, the influence expanded until it reached the general public and, in particular, those who had contact with patients, such as health care workers. As a result, mental health investigation, follow-up, and therapy are required to preserve the mental health of health care workers as well as the general population.

文摘Objective Intracerebral hemorrhage(ICH)refers to predominant,sporadic,and non-traumatic bleeding in the brain parenchyma.The PI3K/AKT/mTOR signaling pathway is an important signal transduction pathway regulated by enzyme-linked receptors and has many biological functions in mammals.It plays a key role in neuronal metabolism,gene expression regulation,and tissue homeostasis in the healthy and diseased brain.Methods In the present study,the role of the PI3K/AKT/mTOR pathway inhibitor chrysophanol(CPH)(10 mg/kg and 20 mg/kg,orally)in the improvement of ICH-associated neurological defects in rats was investigated.Autologous blood(20µL/5 min/unilateral/intracerebroventricular)mimics ICH-like defects involving cellular and molecular dysfunction and neurotransmitter imbalance.The current study also included various behavioral assessments to examine cognition,memory,and motor and neuromuscular coordination.The protein expression levels of PI3K,AKT,and mTOR as well as myelin basic protein and apoptotic markers,such as Bax,Bcl-2,and caspase-3,were examined using ELISA kits.Furthermore,the levels of various neuroinflammatory cytokines and oxidative stress markers were assessed.Additionally,the neurological severity score,brain water content,gross brain pathology,and hematoma size were used to indicate neurological function and brain edema.Results CPH was found to be neuroprotective by restoring neurobehavioral alterations and significantly reducing the elevated PI3K,AKT,and mTOR protein levels,and modulating the apoptotic markers such as Bax,Bcl-2,and caspase-3 in rat brain homogenate.CPH substantially reduced the inflammatory cytokines like interleukin(IL)-1β,IL-6,and tumor necrosis factor-α.CPH administration restored the neurotransmitters GABA,glutamate,acetylcholine,dopamine,and various oxidative stress markers.Conclusion Our results show that CPH may be a promising therapeutic approach for overcoming neuronal damage caused by the overexpression of the PI3K/AKT/mTOR signaling pathway in ICH-induced neurological dysfunctions in rats.
文摘As the first international sporting event scheduled since the outbreak of the novel coronavirus disease 2019(COVID-19)pandemic,the Beijing XXIV Olympic Winter Games were officially held in China between the 4th and 20th of February 2022.1 According to the International Olympic Committee(IOC),there were approximately 2900 elite athletes from 91 National Olympic Committees competing in 109 events during the 16 days of the Games.2 In fact,under the conditions of a global pandemic,mass gatherings during large-scale sporting events represent a conducive environment for viral transmission given the close,prolonged,and frequent interactions between participants;this includes an increased risk of transmission of severe acute respiratory syndrome coronavirus 2(SARS-CoV-2).
文摘Background: Acute Coronary Syndrome (ACS)-associated mortality is considered high and still raising, where outcomes can be improved through immediate treatment initiation. Knowledge, attitudes, beliefs and perceived risk are cognitive factors that can affect patient’s decision to seek care immediately. Therefore, this study aimed to explore knowledge, attitudes, beliefs, and perceived risk for future ACS event among Jordanian ACS patients. Methods: A descriptive, cross-sectional, correlational design was used to conveniently recruit 160 ACS patients from CCUs and medical floors at three Jordanian hospitals using the Modified ACS Response Questionnaire. Results: Almost, 65% of participants had low level of ACS knowledge, specifically regarding untraditional ACS symptoms. Some negative attitudes and beliefs toward ACS were found. There was a moderate positive correlation between knowledge score and all of attitudes, beliefs and perceived risk score (r = 0.549, p Conclusion: Inadequate ACS knowledge, negative attitudes and beliefs toward ACS were associated with low perceived risk for future ACS event. Therefore, it is a priority to develop strategies that consider improving ACS patients’ knowledge, attitudes, beliefs and perceived risk. This could be effective to enhance patient’s decision to seek care and reduce ominous outcomes.
文摘BACKGROUND We present a rare case of status epilepticus in a 56-year-old man which arose as a complication after vaccination with the coronavirus disease 2019(COVID-19)mRNA-1273 vaccine.The patient's history included well-compensated secondary epilepsy.The root cause of the situation was a fever which had developed as a side effect of the vaccination.CASE SUMMARY A 56-year-old man received the first dose of mRNA-1273 vaccine against the severe acute respiratory syndrome-coronavirus-2.The vaccine was administered intramuscularly(100 mg,0.5 mL).The next morning the man was found to be suffering from fever and headaches while at the same time experiencing general weakness.He lost consciousness suddenly and experienced generalized clonic seizures which turned into status epilepticus.When the Emergency Medical Service arrived the patient was unconscious with spontaneous breathing and generalized clonic seizures.It was necessary to administer diazepam repeatedly.It was also necessary to administer high doses of levetiracetam and temporary propofol.The status epilepticus was brought under control approximately 90 min after the patient’s transport to the Emergency Department.A follow-up electroencephalogram no longer revealed abnormal indications of epileptic fit.The patient was temporarily hospitalized in the Intensive Care Unit and after seven days care was discharged without any further apparent effects.CONCLUSION There is currently no specific treatment against COVID-19.Therefore,the benefits of COVID-19 vaccine protection outweigh the risks.

文摘AIM:To investigate whether palatable sweet foods have a beneficial effect on chronic stress-induced colonic motility and inflammatory cytokines.METHODS:Adult male rats were divided into 3groups:control(CON,n=5),chronic variable stress with chow(CVS-A,n=6),and chronic variable stress with chow and sweet food(CVS-B,n=6).The rats were fed standard rodent chow as the chow food and/or AIN-76A as the sweet food.A food preference test for AIN-76A was performed in another group of normal rats(n=10)for twelve days.Fecal pellet output(FPO)was measured for 6 wk during water bedding stress in the CVS groups.The weight of the adrenal glands,adrenocorticotropic hormone(ACTH)and corticosterone levels in plasma were measured.The expression levels of transforming growth factor-β,interleukin(IL)-2,and interferon-gamma(IFN-γ)were measured in the distal part of colonic tissues and plasma using Western blot analysis.RESULTS:In sweet preference test,all rats initially preferred sweet food to chow food.However,the consumption rate of sweet food gradually decreased and reduced to below 50%of total intake eight days after sweet food feeding.Accumulated FPO was higher in the CVS-A group compared with the CVS-B group over time.All stress groups showed significant increases in the adrenal to body weight ratio(CVS-A,0.14±0.01;CVS-B,0.14±0.01)compared with the control group(0.12±0.01,P<0.05).The plasma corticosterone and ACTH levels were significantly higher in the CVS-A(537.42±32.95,44.44±6.54 pg/mL)and CVS-B(655.07±30.82,65.46±4.44 pg/mL)groups than in the control group(46.96±13.29,8.51±1.35 pg/mL,P<0.05).Notably,the ratio of corticosterone to ACTH was significantly increased in the CVS-A group only.Rats exposed to CVS displayed significantly increased expression of IL-2 and IFN-γin the plasma and distal colon compared to the control group,whereas this effect was significantly attenuated in the CVS-B group.CONCLUSION:These results suggest that concurrent sweet food ingestion during CVS might have an effect on the reduction of stress-induced colonic hyper-motility and pro-inflammatory cytokine production in rats.

文摘Dear editor,Airbags are an example of passive preventive measures reducing the risk of severe injury or death from a motor vehicle accident. However, airbags have also been described as a source of injuries related to airbag deployment. Typical airbag-related injuries are eye injuries, cervical spine injuries, rib fractures, cardiac injuries, extremity injuries, and thoracic aortic rupture(TAR).[1-3] Approximately one-third of patients with TAR who survive till hospital admission die before surgical treatment.[4] We present a patient with TAR after a lowspeed motor vehicle accident with rapidly deteriorating vital signs and subsequent death on the scene.
文摘Mechanical CPR (cardiopulmonary resuscitation) devices help performing correct chest compressions in the event of a cardiorespiratory arrest. These devices are comfortable and useful, they keep chest compression following the recommendations as they do not depend on interpersonal variability, they do not get tired, their use is simple and one of the rescuers is released from this task, thus facilitating the assistance. Besides, their use in transport conditions makes it safer. However, when coming to results, these mechanical CPR devices have not clearly demonstrated such an advantage, neither in the field of cardiac arrest, nor in organ preservation in the case of donors after cardiac death. In donors after cardiac death they are widely used by most of the emergency services involved, but a number of injuries produced in lungs during the early years of their use have made it controversial. In this paper we make a review of the road traveled by mechanical CPR devices and of the main articles which mark the way.
文摘This study is aimed to investigate exercise behaviors (frequency and duration) among Jordanian diabetic patients, and their correlation with their physical characteristics and perceived exercise benefits and barriers, exercise self efficacy, and exercise planning. An exploratory descriptive design was utilized using the cross-sectional survey with self-reported questionnaires (Demographics, Charlson Comorbidity Index, Exercise Self-Efficacy Scale, Exercise Benefits and Barriers Scale, and Commitment to a Plan for Exercise Scale). A convenience sample of 115 Jordanians with diabetes mellitus was recruited from diabetes outpatient clinics. Participants reported an average number of 3.2 physical activities per week (average of 2.9 hours), with walking being the most common activity. Participant’s body mass index, comorbidity index, and exercise self-efficacy were correlated with both frequency and duration of exercise (r = -0.393, -0.286, 0.219 and -0.272, 0.383, 0.260, respectively). A predictive model of five predictors (age, BMI, CCI, exercise self efficacy, and perceived exercise barriers) that significantly predicted exercise duration (R<sup>2</sup> = 0.34, F = 9.14, P < 0.000) was found. Diabetic patients were found to exercise less than optimum. Illness itself was not a cause of not exercising compared to lack of time and desire. Factors that can enhance or inhibit participants’ engagement in exercise should be included in designing tailored exercise educational programs.
