RESUMO
BACKGROUND: Pedestrian traffic injuries are a rising public health concern worldwide. In rapidly urbanizing countries like Saudi Arabia, these injuries account for a considerable proportion of trauma cases and represent a challenge for healthcare systems. The study aims to analyze the key characteristics, seasonality, and outcomes of pedestrian traffic injuries in Riyadh, Saudi Arabia. METHODS: This study was a retrospective cohort analysis of all pedestrian traffic injuries presented to King Saud Medical City, Riyadh, and included in the Saudi Trauma Registry (STAR) database between August 1, 2017, and December 31, 2022. The analysis of metric and nominal variables was reported as mean (standard deviation, SD) or median (interquartile range, IQR) and frequencies (%), respectively. A logistic regression analysis was performed to examine the influence of patients' pre-hospital vitals and key characteristics on arrival at the ED on the need for mechanical ventilation and in-hospital mortality. RESULTS: During the study period, 1062 pedestrian-injured patients were included in the analysis, mostly males (89.45%) with a mean (SD) age of 33.44 (17.92) years. One-third (35.88%) of the patients were Saudi nationals. Two-thirds (67.04%) of the injuries occurred from 6 p.m. until 6 a.m. Compared to other years, a smaller % of injury events (13.28%) were noticed during the COVID-19 pandemic (2020). Half (50.19%) of the patients were transported to the emergency department by the Red Crescent ambulance, and 19.68% required intubation and mechanical ventilation. Most of the patients (87.85%) were discharged home after completion of treatment, and our cohort had a 4.89% overall mortality. The logistic regression analysis showed the influence of patients' pre-hospital vitals and key characteristics on arrival at the ED on the need for mechanical ventilation (Chi2 = 161.95, p < 0.001) and in-hospital mortality (Chi2 = 63.78, p < 0.001) as a whole significant. CONCLUSION: This study details the demographic, temporal, and clinical trends of pedestrian traffic injuries at a major Saudi trauma center. Identifying high-risk individuals and injury timing is crucial for resource allocation, targeting road safety interventions like public awareness campaigns and regulatory reforms, and improving prehospital care and patient outcomes.

STUDY OBJECTIVE: Chest pain is one of the most common reasons for emergency ambulance calls. Patients are routinely transported to the hospital to prevent acute myocardial infarction (AMI). We evaluated the diagnostic accuracy of clinical pathways in the out-of-hospital environment. The Troponin-only Manchester Acute Coronary Syndromes decision aid and History, ECG, Age, Risk Factors, Troponin score require cardiac troponin (cTn) measurement, whereas the History and ECG-only Manchester Acute Coronary Syndromes decision aid and History, ECG, Age, Risk Factors score do not. METHODS: We conducted a prospective diagnostic accuracy study at 4 ambulance services and 12 emergency departments between February 2019 and March 2020. We included patients who received an emergency ambulance response in whom paramedics suspected AMI. Paramedics recorded the data required to calculate each decision aid and took venous blood samples in the out-of-hospital environment. Samples were tested using a point-of-care cTn assay (Roche cobas h232) within 4 hours. The target condition was a diagnosis of type 1 AMI, adjudicated by 2 investigators. RESULTS: Of 817 included participants, 104 (12.8%) had AMI. Setting the cutoff at the lowest risk group, Troponin-only Manchester Acute Coronary Syndromes had 98.3% sensitivity (95% confidence interval 91.1% to 100%) and 25.5% specificity (21.4% to 29.8%) for type 1 AMI. History, ECG, Age, Risk Factors, Troponin had 86.4% sensitivity (75.0% to 98.4%) and 42.2% specificity (37.5% to 47.0%); History and ECG-only Manchester Acute Coronary Syndromes had 100% sensitivity (96.4% to 100%) and 3.1% specificity (1.9% to 4.7%), whereas History, ECG, Age, Risk Factors had 95.1% sensitivity (88.9% to 98.4%) and 12.1% specificity (9.8% to 14.8%). CONCLUSION: With point-of-care cTn testing, decision aids can identify patients at a low risk of type 1 AMI in the out-of-hospital environment. When used alongside clinical judgment, and with appropriate training, such tools may usefully enhance out-of-hospital risk stratification.

OBJECTIVES: The Manchester Acute Coronary Syndromes ECG (MACS-ECG) prediction model calculates a score based on objective ECG measurements to give the probability of a non-ST elevation myocardial infarction (NSTEMI). The model showed good performance in the emergency department (ED), but its accuracy in the pre-hospital setting is unknown. We aimed to externally validate MACS-ECG in the pre-hospital environment. METHODS: We undertook a secondary analysis from the Pre-hospital Evaluation of Sensitive Troponin (PRESTO) study, a multi-centre prospective study to validate decision aids in the pre-hospital setting (26 February 2019 to 23 March 2020). Patients with chest pain where the treating paramedic suspected acute coronary syndrome were included. Paramedics collected demographic and historical data and interpreted ECGs contemporaneously (as 'normal' or 'abnormal'). After completing recruitment, we analysed ECGs to calculate the MACS-ECG score, using both a pre-defined threshold and a novel threshold that optimises sensitivity to differentiate AMI from non-AMI. This was compared with subjective ECG interpretation by paramedics. The diagnosis of AMI was adjudicated by two investigators based on serial troponin testing in hospital. RESULTS: Of 691 participants, 87 had type 1 AMI and 687 had complete data for paramedic ECG interpretation. The MACS-ECG model had a C-index of 0.68 (95% CI: 0.61 to 0.75). At the pre-determined cut-off, MACS-ECG had 2.3% (95% CI: 0.3% to 8.1%) sensitivity, 99.5% (95% CI: 98.6% to 99.9%) specificity, 40.0% (95% CI: 10.2% to 79.3%) positive predictive value (PPV) and 87.6% (87.3% to 88.0%) negative predictive value (NPV). At the optimal threshold for sensitivity, MACS-ECG had 50.6% sensitivity (39.6% to 61.5%), 83.1% specificity (79.9% to 86.0%), 30.1% PPV (24.7% to 36.2%) and 92.1% NPV (90.4% to 93.5%). In comparison, paramedics had a sensitivity of 71.3% (95% CI: 60.8% to 80.5%) with 53.8% (95% CI: 53.8% to 61.8%) specificity, 19.7% (17.2% to 22.45%) PPV and 93.3% (90.8% to 95.1%) NPV. CONCLUSION: Neither MACS-ECG nor paramedic ECG interpretation had a sufficiently high PPV or NPV to 'rule in' or 'rule out' NSTEMI alone.

Number of factors, including newly emerging infectious diseases and an increase in multi-drug resistant microbial pathogens with particular relevance for Gram-positive bacteria, make the treatment of infectious diseases in hospital-based healthcare a major challenge in the medical community. 4-Aminobenzoic acid (PABA), has demonstrated a variety of biological actions particularly, antimicrobial activity. In our study we coupled this vitamin-like molecule with different isatin derivatives. We investigated the antibacterial activity of the synthesized Schiff's bases. The compounds showed high selective activity against Gram-positive bacteria and showed weak or no activity against both Gram-negative bacteria and fungi. Compound 2a showed highest activity against S. aureus and B. subtilis (MIC 0.09 mmol/L). Additionally, these substances exhibit strong anti-B. Subtilis biofilm formation. We were able to shed insight on the binding mode of these new inhibitors using in silico docking of the compounds in the binding sites of a 3D structure of B. subtilis histidine kinase/Walk. The binding free energy of the compound 2a to the catalytic domain walk, of histidine kinase enzyme of B. subtilis bacteria, was calculated using molecular mechanics/generalized born surface area scoring. The key residues for macromolecule-ligand binding were postulated. The optimized 3D protein-ligand binding modes shed light on the B. subtilis HK/Walk-ligand interactions that afford a means to assess binding affinity to design new HK/Walk inhibitor as antibacterial agents.
RESUMO
BACKGROUND: Pulmonary hypertension is a common and serious complication of chronic obstructive pulmonary disease (COPD). Studies suggest that cigarette smoke can initiate pulmonary vascular remodelling by stimulating cell proliferation; however, the underlying cause, particularly the role of vasoactive prostanoids, is unclear. We hypothesize that cigarette smoke extract (CSE) can induce imbalanced vasoactive prostanoid release by differentially modulating the expression of respective synthase genes in human pulmonary artery smooth muscle cells (PASMCs) and endothelial cells (PAECs), thereby contributing to cell proliferation. METHODS: Aqueous CSE was prepared from 3R4F research-grade cigarettes. Human PASMCs and PAECs were treated with or without CSE. Quantitative real-time RT-PCR and Western blotting were used to analyse the mRNA and protein expression of vasoactive prostanoid syhthases. Prostanoid concentration in the medium was measured using ELISA kits. Cell proliferation was assessed using the cell proliferation reagent WST-1. RESULTS: We demonstrated that CSE induced the expression of cyclooxygenase-2 (COX-2), the rate-limiting enzyme in prostanoid synthesis, in both cell types. In PASMCs, CSE reduced the downstream prostaglandin (PG) I synthase (PGIS) mRNA and protein expression and PGI2 production, whereas in PAECs, CSE downregulated PGIS mRNA expression, but PGIS protein was undetectable and CSE had no effect on PGI2 production. CSE increased thromboxane (TX) A synthase (TXAS) mRNA expression and TXA2 production, despite undetectable TXAS protein in both cell types. CSE also reduced microsomal PGE synthase-1 (mPGES-1) protein expression and PGE2 production in PASMCs, but increased PGE2 production despite unchanged mPGES-1 protein expression in PAECs. Furthermore, CSE stimulated proliferation of both cell types, which was significantly inhibited by the selective COX-2 inhibitor celecoxib, the PGI2 analogue beraprost and the TXA2 receptor antagonist daltroban. CONCLUSIONS: These findings provide the first evidence that cigarette smoke can induce imbalanced prostanoid mediator release characterized by the reduced PGI2/TXA2 ratio and contribute to pulmonary vascular remodelling and suggest that TXA2 may represent a novel therapeutic target for pulmonary hypertension in COPD.

Commiphora gileadensis (CG) is a small tree distributed throughout the Middle East. It was traditionally used in perfumes in countries in this area. In Saudi Arabia, it was used to treat wounds burns and as an antidote to scorpion stings. This study aimed to evaluate the antimicrobial activity and cutaneous wound healing efficiency of the CG extracts using microbiological tests, rate of wound contraction and histopathological changes. CG plant were extracted using the methanol extraction technique; then, the methanolic extract was characterized using liquid chromatography coupled with mass spectrometry (LC−MS). Afterwards, a six-millimetre (mm) excision wound was induced in 60 male Balb/c mice. Mice were classified into two classes; each class consisted of three groups of 10 mice. In the non-infected wound class, the group I was assigned as control and received normal saline. Group II received gentamicin treatment, and group III treated with CG-methanolic extract. In the Staphylococcus aureus-infected class, group IV received normal saline, and groups V and VI were treated with gentamicin and CG-methanolic extract, respectively. The colonization of infected wounds was determined using colony-forming units (CFUs), and the percentage of wound contraction was measured in all groups. Finally, the histopathologic semi-quantitative determination of wound healing was evaluated by inflammatory cell infiltration, the presence of collagen fibres and granulation tissue, and the grade of re-epithelization. Composition analysis of the methanolic extract confirmed the presence of a high amount of ceramide (69%) and, to a lesser extent, hexosylceramide (18%) and phosphatidylethanolamine (7%) of the total amount. Additionally, there was a statistically significant difference between the percentage of wound contraction in the CG-treated and control groups in both Staphylococcus aureus-infected and non-infected wounds (p < 0.01). The colonization of the infected wounds was lower in the group treated with CG than in the control group (p < 0.01). In both non-infected and infected wounds, the CG-treated group showed significant statistical differences in inflammatory cell infiltration, collagen fibres, re-epithelization and granulation tissue formation compared with the control group (p < 0.01). The CG extract possesses antibacterial and anti-inflammatory properties that induce wound healing.

OBJECTIVE: Point-of-care (POC) cardiac troponin (cTn) assays have a rapid turnaround time but are generally less sensitive than laboratory-based assays. Previous research found that the Abbott i-Stat cardiac troponin I (cTnI) assay has good diagnostic accuracy when used with the Troponin-only Manchester Acute Coronary Syndromes (T-MACS) decision aid and serial sampling over 3 hours. Accuracy of other assays may differ. We therefore evaluated the diagnostic accuracy of a different POC cTnI assay with serial sampling over 3 hours, both with T-MACS and when used alone. METHODS: In a prospective diagnostic accuracy study at eight EDs in England (July 2015-October 2017), we collected clinical data from consenting adults with suspected ACS at the time of assessment in the ED. Blood samples were drawn on arrival and 3 hours later for POC cTnI (Cardio 3 Triage, Alere). The target condition was an adjudicated diagnosis of acute myocardial infarction (AMI), based on reference standard serial laboratory-based cTn testing. We calculated test characteristics for POC cTnI using the limit of detection (LoD, 0.01 µg/L) and the T-MACS decision aid. RESULTS: Of 347 participants, 59 (14.9%) had AMI. With serial POC cTnI testing over 3 hours, POC cTnI at the LoD cut-off ruled out AMI in 193 (55.6%) patients with 98.1% sensitivity (95% CI 89.9% to 100.0%) and 99.5% negative predictive value (NPV, 95% CI 96.5% to 99.9%). T-MACS ruled out AMI in 117 (33.7%) patients with 98.1% sensitivity (95% CI 89.9% to 100%) and 99.2% NPV (95% CI 94.3% to 99.9%). T-MACS ruled in AMI with 97.9% specificity (95% CI 95.8% to 99.5%) and 83.7% positive predictive value (95% CI 70.6% to 91.7%). CONCLUSIONS: With serial sampling over 3 hours, the Alere Cardio 3 Triage cTnI assay has relatively high NPV for AMI using either the LoD cut-off alone or the T-MACS decision aid. However, wide CIs around the measures of diagnostic accuracy mean that further prospective testing of this strategy is required before clinical implementation. TRIAL REGISTRATION NUMBER: UKCRN 18000.

A shortcut review of the literature was carried out to establish whether prehospital point of care (POC) troponin tests are reliable and accurate enough to detect acute coronary syndrome (ACS) in adult patients.Nine papers were found to be relevant to the clinical question following the below-described search strategies. The author, date and country of publication, patient group studied, study type, relevant outcomes, results and study weaknesses of those best papers are tabulated. It is concluded that based on the currently available evidence, POC troponin assays are insufficiently sensitive to 'rule out' ACS in the prehospital environment.

Introduction Electronic cigarettes (e-cigarettes) are rising in popularity among young adults and teenagers. Previous studies have shown that among high and middle schoolers, the percentage of e-cigarette smokers was noticeably higher than tobacco cigarette smokers. Various research papers focusing on different communities have reported a low-to-moderate level of knowledge and awareness of e-cigarette's effects on health. E-cigarettes were initially advertised as devices to help people quit smoking, but the use of e-cigarettes in modern days has changed considerably. A big chunk of the population perceived that e-cigarettes have no harmful effects because they are nicotine-free and thus are used as a replacement for regular cigarettes rather than as a way to quit smoking. Objectives The study aimed to assess the perception of e-cigarette consumption and associated factors among the Saudi population in Jeddah city. Methodology A cross-sectional study was conducted on the Saudi population in Jeddah, Saudi Arabia, during the year 2023. The study assessed the participant's perceptions of e-cigarette consumption and its risk factors. A pre-existing online questionnaire created by Google Forms was distributed among the population through social media applications to collect data after obtaining their informed consent. Results A total of 515 participants were included in this study. Relatives and friends were the most common sources (54%) for information about e-cigarettes. Of the sample, 17.5% thought that e-cigarettes were safer than conventional cigarettes, 13.4% used e-cigarettes on a regular basis, and 65% had not smoked electronically before. Vaping pushed only 17.2% to try traditional tobacco cigarettes, and 25% stopped using traditional tobacco products after starting to smoke e-cigarettes. Gender, age group, and total family salary were the associated factors with the use of e-cigarettes. In addition, an association between the perception of e-smoking and its use was noticed, as well as a significant association between gender and withdrawal symptoms. Conclusion A minority of the participants perceived that e-cigarette smoking is safer than conventional methods of smoking. The majority did not practice e-smoking at all. Furthermore, results showed that relatives and friends were the most common sources of information. The findings from the correlation testing underscore several noteworthy associations within the studied population. Notably, gender, age, total family salary, and occupation exhibited statistically significant correlations with e-cigarette usage.
RESUMO
Introduction Laryngopharyngeal reflux (LPR) is a condition characterized by the backflow of gastric contents rising through the esophagus, affecting the aerodigestive tract and leading to throat symptoms such as hoarseness, chronic cough, and throat clearing. LPR is recognized as a separate condition from gastroesophageal reflux disease, despite the fact that they both involve the backflow of the stomach contents as their primary pathology. Our study aimed to evaluate the prevalence of LPR within the population of Saudi Arabia. Methods A cross-sectional study was conducted using an electronic questionnaire from August to November 2023, involving participants from all five regions of Saudi Arabia. A total of 1140 participants completed the questionnaire, which included the Reflux Symptom Index (RSI) to assess the prevalence of LPR. Results LPR was found to be prevalent in 31.2% of the study population, with the most common associated demographics being female gender (p = 0.032) and adults aged 36-45 years (p = 0.006). However, no significant relationship was observed based on region of residence or other demographic factors such as education level or occupation. Conclusion LPR has a high prevalence in the population of Saudi Arabia. Therefore, further research and awareness about this condition are warranted to better understand its impact, improve diagnosis, and develop appropriate management strategies.
RESUMO
Aim: The Saudi Out-of-Hospital Cardiac Arrest Registry (SOHAR) is the first out-of-hospital cardiac arrest (OHCA) registry in Saudi Arabia. This study aimed to describe the epidemiology and outcomes of OHCA in Saudi Arabia. Methods: The SOHAR is a prospective data collection system. Data were collected monthly from defined regions, and registry measured variables were adopted from the Utstein recommendations. Results: During the period from 01/01/2019 to 31/12/2022, 3671 patients were included in the registry. The mean age was 62 years, and 6.5% (240) of patients were under the age of 18 years. The most common cause of OHCA was medical 3439 (93.6%). A total of 641 (17.4%) and 129 (3.9%) had presumed cardiac and respiratory causes. Additionally, most OHCA in Saudi Arabia (3034, 82.6%) occurred at home. Prehospital Return Of Spontaneous Circulation (ROSC) was achieved in 275 (7.4%) cases, and 491 (13.3%) patients were pronounced dead upon arrival at the hospital. Survival to hospital discharge was achieved in 107 (2.9%) of the cases, and good neurological outcomes, defined as a Cerebral Performance Category (CPC) of 1-3, occurred in < 0.5% of patients. Conclusion: The Saudi out-of-hospital ROSC was 7.4%. The survival to hospital discharge rate was 2.9%, and less than 1% of patients were discharged with good neurological outcomes. Further research and the continuation of registry data collection is highly recommended. Additionally, a national-level out-of-hospital cardiac arrest system is recommended to ensure the standardization of medical care provided to patients with OHCA.
RESUMO
Background: Obesity is common among chronic obstructive pulmonary disease (COPD) patients and is associated with an increase in acute exacerbation episodes. However, data on obesity's impact on and association with clinical outcomes among patients with COPD are limited. This study aimed to determine overweight and obesity prevalence and associations with spirometry profiles, intensive care unit (ICU) admission, and comorbidities in patients with COPD. Methods: In this retrospective cohort study, we reviewed the electronic health records of adult individuals diagnosed with COPD who visited the studied pulmonary clinics between 1 January 2018 and 31 December 2022 and then collected key demographic variables and relevant clinical outcomes and comorbidities. Results: A total of 474 patients with COPD were included in the final analysis, of whom 60% were male. The occurrences of overweight and obesity were 32.7% and 38.2%, respectively. The presence of comorbidities was high in obese patients (78.4%), followed by overweight patients (63.8%) with COPD. Obese and overweight patients had the highest ward admission rates (38.3% and 34.2%, respectively). ICU admissions were higher in obese and overweight patients (16% and 12%, respectively) compared with normal-weight patients (9%). Although no significant correlation was found between body mass index and spirometry parameters, comorbidities and ICU admission were linked to overweight and obesity in COPD patients (AOR: 1.82 95% CI: 1.15 to 2.86 and AOR: 3.34 95% CI 1.35 to 8.22, respectively). Conclusion: Our findings imply that obesity in COPD is prevalent and is associated with adverse clinical outcomes including a greater number of comorbidities and higher rates of hospitalization and admission to ICUs although no associations were found between body weight and spirometry parameters. Further studies are needed to assess whether implementing and optimising obesity screening and management at an early stage in COPD can prevent further deterioration.

Objective. To describe heated humidified high-flow nasal cannulas (HHHFNC) utilization in level III neonatal intensive care units (NICUs) in Saudi Arabia. Methods. A prospective cross-sectional study using an electronic web-based questionnaire. The survey targeted level III NICUs hospitals using HHHFNCs, covering HHHFNC availability, protocols, patient characteristics, and indications. It also collected opinions on the benefits of HHHFNCs compared to nasal continuous positive airway pressure (nCPAP). Results. Out of 47 government-level III neonatal intensive care units, 35 (74%) responded to the survey. Among the included units, 46% had guidelines for HHHFNC use. Additionally, 51% reported using HHHFNC in infants of all gestational ages. The primary indication for HHHFNC use was weaning off nCPAP (34%), with 60% of the respondents noting its advantages for kangaroo care and breastfeeding. Conclusion. HHHFNC are increasingly prevalent in NICUs in Saudi Arabia. However, there remain no clear policies or guidelines regarding their use in preterm infants.
RESUMO
Introduction: Imposter syndrome is common among health disciplinary students, leading to serious consequences. However, the impact of imposter syndrome on self-esteem and quitting intention among respiratory therapy students has not been well researched. Objective: To report on the prevalence of imposter syndrome and assess its impacts on self-esteem and quitting intention among respiratory therapy students in Saudi Arabia. Methods: A nonprobability cross-sectional questionnaire using the Clance Impostor Phenomenon Scale and the Rosenberg Self-Esteem Scale was self-administered and distributed among respiratory therapy students between October 2022 and April 2023. Data analysis was performed using Descriptive and inferential statistics. Results: Of the 1500 respiratory therapy students invited to participate in the study, 901 surveys were completed; and thus, included in the final analysis. Of whom, 92% were presented with imposter syndrome: 44% with moderate, 35% with frequent, and 13% with intense feelings. In addition, 60% of respiratory therapy students and interns experienced low self-esteem, while only 0.5% indicated high self-esteem. More than 50% of the study participants thought about quitting the respiratory therapy program, and 30% have been diagnosed with psychological disorders. Furthermore, there was a significant association between imposter syndrome and low self-esteem, p < 0.001. Factors associated with imposter syndrome and low self-esteem were family income (<0.005) and parents' education (<0.005), quitting intention (<0.005), and having been diagnosed with psychological disorders (<0.005). Genders, academic levels, and grade point average were not associated with either imposter syndrome or self-esteem (>0.005). Conclusion: Imposter syndrome and low self-esteem are prevalent among respiratory therapy students, both of which are associated with considering leaving the respiratory therapy program. Effective interventions should be implemented to ameliorate the symptoms imposter syndrome and low self-esteem; thus, improving the academic experience of respiratory therapy students.
RESUMO
Background Vaccine hesitancy is a growing concern worldwide, particularly during the COVID-19 pandemic. The aim was to investigate vaccine hesitancy and its determinants among parents in Taif, Saudi Arabia. Methods A cross-sectional study was conducted among parents using a validated and reliable questionnaire, the parent attitudes about childhood vaccines (PACV). Parents of children aged (two months to seven years) attending primary health care centers (PHCC) outpatient clinics were selected using a stratified sampling technique and interviewed to fill out the pre-structured questionnaire. Result The study included 301 parents, with 41.2% between the ages of 30-39 years and 25.2%% between 40-49 years. Mothers constituted 69.1% of the respondents. The most common sources of information regarding vaccinations were the doctor (34.9%), the internet (27.9%), and social media (16.6%). COVID-19 influenced the beliefs of more than half (52.5%) of parents regarding the importance of vaccinations. The median PACV score for vaccination hesitancy was 23.3/100, interquartile range (IQR) (13.3-33.3). The highest hesitation was among the age group of 30-39 years old (21.6%) and those whose beliefs were not influenced by the COVID-19 pandemic (16.1% vs. 5.7%) (p-value=0.003). The study found a significant difference in vaccine hesitancy rates between the different sources of information (p-value <0.001); parents who got their information about vaccinations from social media were more likely to be hesitant about vaccinations (40%). Concerns about side effects (93.8%), thinking that vaccines are not safe (84.4%), and thinking that fewer vaccines are needed (78.1%) were the top three factors influencing vaccine hesitancy. Conclusion This study urges promoting vaccine uptake through healthcare providers and combating vaccine misinformation on social media. Additionally, addressing safety concerns and misconceptions about vaccine necessity, and focusing on first-time parents, younger parents, and those with lower socioeconomic status are recommended strategies to improve vaccine uptake rates.
RESUMO
Background: Pre-hospital care providers are the first line of contact when emergencies occur. They are at high risk of mental health disorders associated with trauma and stress. The magnitude of their stress could increase during difficult times such as the COVID-19 pandemic. Objectives: This study reports on the state of mental well-being and the degree of psychological distress among pre-hospital care workers (paramedics, emergency medical technicians, doctors, paramedic interns and other healthcare practitioners) during the COVID-19 pandemic in Saudi Arabia. Methods: The study was a cross-sectional survey study in Saudi Arabia. A questionnaire was distributed among pre-hospital care workers in Saudi Arabia during the first wave of the COVID-19 pandemic. The questionnaire was based on the Kessler Psychological Distress Scale (K10) and the World Health Organization Well-Being Index (WHO-5). Results: In total, 427 pre-hospital care providers completed the questionnaire; 60% of the respondents had scores of more than 30 in the K10 and were likely to have a severe disorder. The WHO-5 showed a similar percentage of respondents with a score of more than 50 and coded as having poor well-being. Conclusions: The findings of this study provide evidence around mental health and well-being for pre-hospital care workers. They also highlight the need to better understand the quality of mental health and well-being for this population and to provide appropriate interventions to improve their quality of life.

Purpose: Paramedics' decision to notify receiving hospitals and transport patients to an appropriate healthcare facility is based on the Prediction of Intensive Care Unit (ICU) and Hospital Admissions guide. This study aimed to assess the paramedics' gestalt on both ward and ICU admission. Patients and Methods: A prospective study was conducted at King Abdulaziz Medical City between September 2021 and March 2022. Paramedics were asked several questions related to the prediction of the patient's hospital outcome, including emergency department (ED) discharge or hospital admission (ICU or ward). Additional data, such as the time of the ambulance's arrival and the staff years of experience, were collected. The categorical characteristics are presented by frequency and percentage for each category. Results: This study included 251 paramedics and 251 patients. The average age of the patients was 62 years. Of the patients, 32 (12.7%) were trauma, and 219 (87.3%) were non-trauma patients. Two-thirds of the patients (n=171, 68.1%) were predicted to be admitted to the hospital, and 80 (31.8%) of the EMS staff indicated that the patient do not need a hospital or an ambulance. The sensitivity, specificity, PPV, and NPV of the emergency medical service (EMS) staffs' gestalt for patient admission to the hospital were, respectively (77%), (33%), (16%), and (90%). Further analysis was reported to defend the EMS staffs' gestalt based on the level of EMS staff and the nature of the emergency (medical vs trauma), are reported. Conclusion: Our study reports a low level of accurately predicting patient admission to the hospital, including the ICU. The results of this study have important implications for enhancing the accuracy of EMS staff predictive ability and ensuring that patients receive appropriate care promptly.
RESUMO
Acute respiratory infections block the bronchial and/or nasal systems' airways. These infections may present in a variety of ways, from minor symptoms like the common cold to more serious illnesses like pneumonia or lung collapse. Acute respiratory infections cause over 1.3 million infant deaths under the age of 5 each year throughout the world. Among all illnesses, respiratory infections make for 6% of the worldwide disease burden. We aimed to examine the admissions related to acute upper respiratory infections admissions in England and Wales for the period between April 1999 and April 2020. This was an ecological study using publicly available data extracted from the Hospital Episode Statistics database in England, and the Patient Episode Database for Wales for the period between April 1999 and April 2020. The acute upper respiratory infections-related hospital admissions were identified using the Tenth Revision of the International Statistical Classification of Diseases and Related Health Problems 5th Edition (used by National Health Service [NHS] to classify diseases and other health conditions) (J00-J06). The total annual number of admissions for various reasons increased by 1.09-fold (from 92,442 in 1999 to 193,236 in 2020), expressing an increase in hospital admission rate of 82.5% (from 177.30 [95% confidence interval {CI}: 176.15-178.44] in 1999 to 323.57 [95%CI: 322.13-325.01] in 2020 per 100,000 persons, P < .01). The most common causes were acute tonsillitis and acute upper respiratory infections of multiple and unspecified sites, which accounted for 43.1% and 39.4%, respectively. Hospital admissions rate due to acute upper respiratory infections increased sharply during the study period. The rates of hospital admissions were higher among those in the age group below 15 and 75 years and above for the majority of respiratory infections, with a higher incidence in females.

Background End-of-life care is essential for individuals with advanced illness and their families, providing comfort, symptom control, and dignity in the final year of life. Additionally, physician competence requires the ability to communicate, make decisions, and create relationships in end-of-life care. This study assesses family physicians' knowledge and attitude regarding end-of-life care in Taif, Saudi Arabia. Methods This descriptive cross-sectional study conducted between October and November 2021 assessed the knowledge and attitudes of 163 family physicians in Taif City, Saudi Arabia, regarding end-of-life care. Using a convenient sampling technique, an adapted and validated questionnaire was administered electronically, collecting sociodemographic information and assessing participants' knowledge and attitudes. Data were analyzed using descriptive statistics in Statistical Product and Service Solutions (SPSS, version 28) (IBM SPSS Statistics for Windows, Armonk, NY). Results Findings included that 41.1% of residents believed the patient and family should be informed about diagnoses and prognoses in advanced diseases. At the same time, attitudes varied, with 45.4% agreeing that discussing such information could lead to patient depression and 42.9% believing it held no privilege for patients. Additionally, 57.7% recognized that grief reactions would occur, but patients would eventually adjust, and 44.8% agreed that discussing diagnoses would decrease patient anxiety. However, limited awareness of advance directives was evident, with 12.3% reporting being well aware and 45.4% having never heard of them. There was uncertainty and hesitancy regarding Do Not Attempt Cardiopulmonary Resuscitation (DNACPR) decisions, with 39.9% being well aware and 46% having heard of it without a strong understanding. Conclusion The findings revealed a mixed landscape, with physicians demonstrating awareness of the importance of transparent communication but needing more knowledge in areas such as advance directives and complex decision-making. The study highlighted the need for targeted education to address these gaps and promote a more informed and consistent approach to end-of-life care.
