ABSTRACT

The role of inflammation has been proven in acute myocardial infarction (AMI) pathogenesis. Due to the effect of NLRP3 gene expression in the inflammation process of MI, we aimed to explore the expression changes and diagnostic power of four inflammation-related miRNAs including miR-17-3p, miR-101-3p, miR-335-3p, miR-296-3p and their potential target, NLRP3, in ST-segment elevation myocardial infarction (STEMI), and non-STEMI (NSTEMI) patients as two major classes of AMI. The expression level of these genes were evaluated in 300 participants equally divided into three groups of STEMI, NSTEMI, and control using quantitative real-time PCR. The expression level of NLRP3 was upregulated in STEMI and NSTEMI patients compared to control subjects. Besides, the expression levels of miR-17-3p, miR-101-3p, and miR-296-3p were significantly downregulated in STEMI and NSTEMI patients compared to controls. The increased expression of NLRP3 had a very strong inverse correlation with miR-17-3p in patients with STEMI and with miR-101-3p in the STEMI and NSTEMI patients. ROC curve analysis showed that the expression level of miR-17-3p had the highest diagnostic power for discrimination between STEMI patients and controls. Remarkably, the combination of all markers resulted in a higher AUC. In summary, there is a significant association between the expression levels of miR-17-3p, miR-101-3p, miR-335-3p, miR-296-3p, and NLRP3 and the incidence of AMI. Although the miR-17-3p expression level has the highest diagnostic power to distinguish between STEMI patients and control subjects, the combination of these miRNAs and NLRP3 could serve as a novel potential diagnostic biomarker of STEMI.

ABSTRACT

OBJECTIVE: Sudden unexplained death in epilepsy (SUDEP) is one of the leading causes of mortality in epilepsy. In this study, cases of definite SUDEP are reported for Bexar County from a 36-year period. METHODS: Death reports by Bexar County Medical Examiner (BCME) from 1983 to 2018 were reviewed to identify cases with definite SUDEP. The findings were based upon investigators' reports, which included medical history, medication list, sleep position, time of death, and pathology reports. In addition to these potential risk factors, body mass indices (BMI), as well as heart, lung, and brain weights were compared between SUDEP victims with therapeutic vs subtherapeutic anti-seizure medication (ASM) levels. RESULTS: Definite SUDEP was identified in 286 cases. The incidence of definite SUDEP was 0.51 ±â€¯0.26/1000 person-years among PWE and 0.56 ±â€¯0.29 per 100,000 person-years among the general population in Bexar County. The median age was 37 years old (interquartile range 27-48), and the majority were male (65%). While 171 (60%) people were prescribed at least one ASM, ASM levels were subtherapeutic in 239 cases (83.6%). Risk factors for SUDEP did not differ between SUDEP victims with therapeutic vs subtherapeutic ASM levels. While BMIs were only slightly increased in adherent vs nonadherent SUDEP victims, they were significantly associated with subtherapeutic ASM levels. Abnormal lung, heart, and brain weights were reported in 48 (16.8%), 67 (23.4%), and 43 (15.0%) SUDEP cases, respectively. SIGNIFICANCE: This study is one of the largest autopsy-based registries of definite SUDEP. Subtherapeutic ASM levels measured in post-mortem blood samples suggest that nonadherence to ASM therapy was a leading risk factor for SUDEP. As BMI was elevated in this cohort, and obesity was significantly associated with subtherapeutic ASM levels, it may also be a risk factor for SUDEP. Case-controlled studies are needed to validate the specific role of obesity and related comorbidities in this population.

ABSTRACT

Importance: Thrombotic events are commonly reported in critically ill patients with COVID-19. Limited data exist to guide the intensity of antithrombotic prophylaxis. Objective: To evaluate the effects of intermediate-dose vs standard-dose prophylactic anticoagulation among patients with COVID-19 admitted to the intensive care unit (ICU). Design, Setting, and Participants: Multicenter randomized trial with a 2 × 2 factorial design performed in 10 academic centers in Iran comparing intermediate-dose vs standard-dose prophylactic anticoagulation (first hypothesis) and statin therapy vs matching placebo (second hypothesis; not reported in this article) among adult patients admitted to the ICU with COVID-19. Patients were recruited between July 29, 2020, and November 19, 2020. The final follow-up date for the 30-day primary outcome was December 19, 2020. Interventions: Intermediate-dose (enoxaparin, 1 mg/kg daily) (n = 276) vs standard prophylactic anticoagulation (enoxaparin, 40 mg daily) (n = 286), with modification according to body weight and creatinine clearance. The assigned treatments were planned to be continued until completion of 30-day follow-up. Main Outcomes and Measures: The primary efficacy outcome was a composite of venous or arterial thrombosis, treatment with extracorporeal membrane oxygenation, or mortality within 30 days, assessed in randomized patients who met the eligibility criteria and received at least 1 dose of the assigned treatment. Prespecified safety outcomes included major bleeding according to the Bleeding Academic Research Consortium (type 3 or 5 definition), powered for noninferiority (a noninferiority margin of 1.8 based on odds ratio), and severe thrombocytopenia (platelet count <20 ×103/µL). All outcomes were blindly adjudicated. Results: Among 600 randomized patients, 562 (93.7%) were included in the primary analysis (median [interquartile range] age, 62 [50-71] years; 237 [42.2%] women). The primary efficacy outcome occurred in 126 patients (45.7%) in the intermediate-dose group and 126 patients (44.1%) in the standard-dose prophylaxis group (absolute risk difference, 1.5% [95% CI, -6.6% to 9.8%]; odds ratio, 1.06 [95% CI, 0.76-1.48]; P = .70). Major bleeding occurred in 7 patients (2.5%) in the intermediate-dose group and 4 patients (1.4%) in the standard-dose prophylaxis group (risk difference, 1.1% [1-sided 97.5% CI, -∞ to 3.4%]; odds ratio, 1.83 [1-sided 97.5% CI, 0.00-5.93]), not meeting the noninferiority criteria (P for noninferiority >.99). Severe thrombocytopenia occurred only in patients assigned to the intermediate-dose group (6 vs 0 patients; risk difference, 2.2% [95% CI, 0.4%-3.8%]; P = .01). Conclusions and Relevance: Among patients admitted to the ICU with COVID-19, intermediate-dose prophylactic anticoagulation, compared with standard-dose prophylactic anticoagulation, did not result in a significant difference in the primary outcome of a composite of adjudicated venous or arterial thrombosis, treatment with extracorporeal membrane oxygenation, or mortality within 30 days. These results do not support the routine empirical use of intermediate-dose prophylactic anticoagulation in unselected patients admitted to the ICU with COVID-19.

ABSTRACT

BACKGROUND: Inflammation plays a major role in coronavirus disease (COVID-19). Factors that convey information about the status of inflammation could predict disease severity and help identify patients prone to clinical deterioration. Here, we aimed to evaluate the predictive value of inflammatory markers on the extent of lung involvement and survival of patients with COVID-19. MATERIALS AND METHODS: Eighty patients with confirmed COVID-19 were enrolled. Demographic, clinical, and laboratory data were collected at admission. All patients underwent chest computed tomography (CT); the extent of lung involvement was assessed by a scoring system. Patients were followed up until death or discharge occurred. Logistic regression analysis was performed to evaluate the association of investigated variables with COVID-19-related death. The association between different variables and CT score was assessed using linear regression model. Receiver operator characteristic curve analysis was applied to identify the predictive value of inflammatory markers and CT score on survival. RESULTS: The mean age of patients was 54.2 ± 15.2 years; 65% were male. Increased neutrophil-to-lymphocyte ratio (ß =0.69, odds ratio [OR] =1.50), platelet-to-lymphocyte ratio (ß =0.019, OR = 1.01), and decreased lymphocyte to C-reactive protein ratio (LCR) (ß = -0.35, OR = 0.62) were significantly associated with a higher CT score and increased odds of death (P < 0.05). Lactate dehydrogenase level was also positively related with extensive lung involvement and death (ß =1.15, OR = 1.52, P < 0.05). The LCR threshold for identifying survivors from nonsurvivors was 0.53 (area under curve [AUC] =0.82, 78% sensitivity and 74% specificity). Lung involvement ≥50% on chest CT was an excellent predictor of death (AUC = 0.83, 81% sensitivity and 79% specificity). CONCLUSION: Daily-performed laboratory tests that represent inflammation have great value for predicting the amount of disease burden and risk of mortality. Moreover, their cost-effectiveness and feasibility turn them into ideal prognostic markers.

ABSTRACT

Background and Purpose- We investigated the prognostic significance of spontaneous intracerebral hemorrhage location in presence of severe intraventricular hemorrhage. Methods- We analyzed diagnostic computed tomography scans from 467/500 (excluding primary intraventricular hemorrhage) subjects from the CLEAR (Clot Lysis: Evaluating Accelerated Resolution of Intraventricular Hemorrhage) III trial. We measured intracerebral hemorrhage engagement with specific anatomic regions, and estimated association of each region with blinded assessment of dichotomized poor stroke outcomes: mortality, modified Rankin Scale score of 4 to 6, National Institutes of Health Stroke Scale score of >4, stroke impact scale score of <60, Barthel Index <86, and EuroQol visual analogue scale score of <50 and <70 at days 30 and 180, respectively, using logistic regression models. Results- Frequency of anatomic region involvement consisted of thalamus (332 lesions, 71.1% of subjects), caudate (219, 46.9%), posterior limb internal capsule (188, 40.3%), globus pallidus/putamen (127, 27.2%), anterior limb internal capsule (108, 23.1%), and lobar (29, 6.2%). Thalamic location was independently associated with mortality (days 30 and 180) and with poor outcomes on most stroke scales at day 180 on adjusted analysis. Posterior limb internal capsule and globus pallidus/putamen involvement was associated with increased odds of worse disability at days 30 and 180. Anterior limb internal capsule and caudate locations were associated with decreased mortality on days 30 and 180. Anterior limb internal capsule lesions were associated with decreased long-term morbidity. Conclusions- Acute intracerebral hemorrhage lesion topography provides important insights into anatomic correlates of mortality and functional outcomes even in severe intraventricular hemorrhage causing obstructive hydrocephalus. Models accounting for intracerebral hemorrhage location in addition to volumes may improve outcome prediction and permit stratification of benefit from aggressive acute interventions.

ABSTRACT

BACKGROUND: Among older adults, pain intensity and pain interference are more common in women than men and associated with obesity and inflammatory markers. OBJECTIVE: We examined whether the obesity and pain relationship is mediated by the high-sensitivity C-reactive protein (hsCRP), a nonspecific marker of systemic inflammation, and whether this relationship differs by sex. METHODS: Items from Medical Outcomes Study Short Form-36 were used to measure pain intensity and pain interference in daily life. Ordinal logistic regression was used to assess the cross-sectional association among body mass index (BMI), hsCRP levels, pain intensity and pain interference using gender-stratified models adjusted for demographic variables. RESULTS: Participants included 667 community-residing adults over the age of 70 years, free of dementia, enrolled in the Einstein Aging Study (EAS). In women (n = 410), pain intensity was associated with obesity [BMI ≥30 vs. normal, odds ratio (OR) = 2.29, 95% confidence interval (CI) 1.43-3.68] and higher hsCRP (OR = 1.28, 95% CI 1.08-1.51). In a model with obesity and hsCRP, both remained significant, but the association between hsCRP and pain intensity was somewhat attenuated. Obesity (OR = 3.04, 95% CI 1.81-5.11) and higher hsCRP levels (OR = 1.30, 95% CI 1.08-1.56) were also independently associated with greater pain interference in women. After adjustment for pain intensity and BMI, hsCRP was no longer associated with pain interference in women. Greater pain intensity and being overweight or obese continued to be significantly associated with pain interference in women. In men (n = 257), obesity and hsCRP were not associated with pain intensity or pain interference. CONCLUSIONS: In women, the relationship between obesity and higher levels of pain intensity or interference may be accounted for by factors related to hsCRP.

ABSTRACT

OBJECTIVE: The aim of this paper was to assess the relationship between pain and sleep in older adults taking depression, stress, and medical comorbidities into account. METHODS: A cross-sectional analysis was performed using Einstein Aging Study, a community-based cohort study of adults aged 70 years and older. Ratings of pain intensity and interference from the Medical Outcomes Study (MOS) Short-Form 36 were used to assign individuals to low-pain versus high-pain severity. Sleep disturbance was assessed using the nine-item sleep problems index from the Medical Outcomes Study Sleep Scale. Other measures included the Geriatric Depression Scale and Perceived Stress Scale (PSS). Linear regression models were used to assess the association between pain grade and sleep disturbance adjusted for demographics, PSS, Geriatric Depression Scale, and other comorbidities. RESULTS: Five hundred sixty-two eligible participants with a mean age of 78.22 years (standard deviation = 5.43) were included; 64% were women. Pain grade [ß = 5.40, 95% confidence interval (CI) 2.56-8.21, p < 0.001] was associated with sleep disturbance after adjusting for demographic variables. In models including pain grade (ß = 3.08, 95% CI 0.32-5.85, p = 0.03) and PSS (ß = 0.57, 95% CI 0.39-0.75, p < 0.001), both were associated with sleep disturbance, although the PSS attenuated the relationship between pain and sleep by 34%. Depression, when added to previous model, was also associated with sleep (ß = 2.17, 95% CI 1.48-2.85, p < 0.001) and attenuated the relationship between pain (ß = 2.41, 95% CI -0.25 to 5.08, p = 0.07) and sleep by 22%. Stratified for depression, we found that pain, stress, and other medical comorbidities were significantly associated with sleep disturbance in non-depressed individuals but not individuals with depression. CONCLUSIONS: Pain, stress, and medical comorbidities are associated with sleep disturbance, especially in non-depressed older adults.

ABSTRACT

OBJECTIVES: To investigate the incidence and determinants of non-fatal injuries, and the cost imposed on victims in an Iranian population aged 15-64 years. DESIGN: Cross-sectional household survey. METHODS: Three-stage probability sampling was conducted for selection of a representative sample of Iranians. Data on the demographics, history and cost of injury were obtained from face-to-face interviews and telephone calls. RESULTS: In total, 7886 subjects were included in this study. The annual incidence rate of all injuries was 905 (95% confidence interval 853-957) per 1000 population (approximately nine injuries per ten Iranians). The mean (±standard error) incidence rates of first aid injuries (FAIs; medical care not required) and medical-attended injuries (MAIs; medical treatment sought) were 737 ± 24 and 168 ± 12 per 1000 population, respectively. Young, urban females were at highest risk for FAIs, and single males were at highest risk for MAIs. The most common injury description was as follows: non-paid work (activity), home (place), inanimate mechanical force (mechanism), upper limb (site of injury) and open wound (type of injury). For MAIs, the most common place of treatment was hospital. Traffic-related injuries had the highest total cost and the lowest out-of-pocket cost. Total and out-of-pocket costs of non-fatal injuries in Iran in 2011 have been estimated to be US$6,111,138,000 and US$1,480,411,000, respectively. CONCLUSION: Non-fatal injuries are an under-recognized public health problem. Cost-control policies are essential to reduce the out-of-pocket cost of injuries.

ABSTRACT

BACKGROUND: Elucidating the epidemiological status of injuries is a critical component of preventive strategies in countries with high incidence of injuries, like Iran. Population-based surveys are able to estimate all types of non-fatal injuries. OBJECTIVES: This study protocol is the core unit in describing Iran's national cost and epidemiology of non-fatal injuries, and also as a guide for other studies. STUDY DESIGN AND METHODS: In a cross-sectional study, 1525 primary sampling units are randomly selected with probability proportional to size regarding the number of households in each enumeration area based on Iran's 2006 national census. Six of the households are randomly selected. One member of each household is chosen using Kish Grid tables. In all, 9150 subjects are selected. Data on demographics are collected. For each injury during the past three months, activity, place, mechanism, site, type and the place of treatment are coded to match the International Classification of Diseases, 10th revision 2012 (ICD10-2012) classifications. Subjects are contacted via telephone to obtain data on cost of injury. Finally, sampling weights are calculated so that data for each respondent can be inflated to represent other individuals in Iran. Quality control and quality assurance issues are discussed. DISCUSSION: Our objectives will describe the present impact and the future priorities of injury prevention in Iran.

ABSTRACT

BACKGROUND AND AIMS: Pericardial effusion (PE) is a prevalent form of pericardial involvement in chronic kidney disease (CKD). This study aims to investigate the clinical and laboratory features associated with PE severity in patients with CKD. METHODS: In this cross-sectional study, we examined the medical records of patients admitted to tertiary hospitals with International Classification of Diseases 10th Revision (ICD-10) codes associated with CKD and PE. We included 112 CKD patients in stage 4 and 5 non-dialysis (ND) with PE for assessing the clinical and laboratory features of severity. RESULTS: Patients were divided into two categories based on the severity of PE. Seventy-two patients had mild and 40 had moderate and severe PE. Univariate analysis of demographic and laboratory features on the date of admission demonstrated that chest pain, dyspnea, serum albumin, and neutrophil-to-lymphocyte ratio (NLR) are associated with the severity of PE. The univariate analysis on the date of echocardiography showed significantly higher white blood cell count (WBC), neutrophil count (percentage and absolute count), and NLR, along with significantly lower lymphocyte percentage and serum albumin among patients with moderate and severe PE. In the multivariable analysis of laboratory features, on admission hypoalbuminemia (p-value = 0.014, OR = 4.03, CI: 1.32-12.25) and NLR greater than 5.5 (p-value = 0.015, OR = 4.22, CI: 1.32-13.50) were significantly associated with moderate and severe PE. In a parallel matter, at the time of echocardiography hypoalbuminemia (p-value = 0.004, OR = 5.38, CI: 1.74-16.65) and neutrophilia (p-value = 0.005, OR = 7.94, CI: 1.89-33.44) were significantly associated with moderate and severe PE. CONCLUSION: Despite advancements in the diagnosis and treatment of CKD, PE is still a concerning issue in these patients. This study revealed that hypoalbuminemia, neutrophilia, and NLR greater than 5.5 could be predictive factors of moderate and severe PE in CKD patients with PE. Further prospective study with larger sample size is needed to confirm these results.

ABSTRACT

Key Clinical Message: The purpose of this case report is to reveal one of the cardiovascular side effects of favipiravir, sinus bradycardia. Abstract: Favipiravir has emerged as a potential treatment for COVID-19, with its antiviral properties showing promise in inhibiting viral replication. However, concerns regarding its safety profile, particularly its cardiac adverse effects, remain a subject of debate. We present the case of a 58-year-old man with a history of diabetes mellitus and chronic obstructive pulmonary disease who developed bradycardia following treatment with favipiravir for COVID-19 pneumonia. Despite being asymptomatic, the patient exhibited sinus bradycardia, which resolved upon discontinuation of favipiravir. Favipiravir has been associated with QT prolongation and sinus bradycardia, though the exact mechanisms remain unclear. Our case adds to the growing body of evidence highlighting the potential cardiac complications of favipiravir therapy in COVID-19 patients. Further research is warranted to clarify the underlying mechanisms and optimize patient management strategies. Clinicians should be cautious for cardiac adverse events when prescribing favipiravir for COVID-19 treatment, especially in patients with preexisting cardiac conditions. Continued research is essential to ensure the safe and effective use of favipiravir in the management of COVID-19.

ABSTRACT

Background: Among various parameters used to predict the outcome of malignancy, nerve invasion has been widely considered as a sign of aggressive behavior in oral cancers. According to the importance of neural invasion in predicting the outcome of oral squamous cell carcinoma (OSCC), this study aimed to evaluate the prevalence of neural and vascular invasion in OSCC. Materials and Methods: In this descriptive, analytical, and cross-sectional study, paraffin-embedded tissues of 62 OSCC in the health center of surgery and pathology were evaluated (2013-2015). Patients' archives were evaluated and recorded in terms of their age and gender. Hematoxylin and eosin (H&E) slides were then examined by two oral pathologists and scrutinized for the presence of nerve involvement, tumor differentiation, vascular and lymph node invasion, and depth of invasion. Data were analyzed using SPSS version 23, t-test, and one-way ANOVA (P < 0.05). Results: Of 62 tumors, 12 patients showed only nerve invasion, 17 cases had only vascular invasion, and seven patients had both neural and vascular invasion, simultaneously, known as a neurovascular invasion. Furthermore, there was no vascular and neural invasion in 26 cases. There was a statistically significant correlation between vascular and neural invasion and the tumor site (P = 0.045). The highest frequency of neural invasion, as well as vascular invasion, was related to tongue tumors. Conclusion: The relation between neural and vascular invasion in OSCC with tumor's location was statistically significant. Lip and tongue carcinoma had shown more neurovascular invasion without relation to gender, age, and cell differentiation.

ABSTRACT

BACKGROUND: Previous studies evaluated the impact of particle matters (PM) on the risk of acute myocardial infarction (AMI) based on local registries. HYPOTHESIS: This study aimed to evaluate possible short term effect of air pollutants on occurrence of AMI based on a specific case report sheet that was designed for this purpose. METHODS: AMI was documented among 982 patients who referred to the emergency departments in Tehran, Iran, between July 2017 to March 2019. For each patient, case period was defined as 24 hour period preceding the time of emergency admission and referent periods were defined as the corresponding time in 1, 2, and 3 weeks before the admission. The associations of particulate matter with an aerodynamic diameter ≤2.5 µm (PM2 .5 ) and particulate matter with an aerodynamic diameter ≤10 µm (PM10 ) with AMI were analyzed using conditional logistic regression in a case-crossover design. RESULT: Increase in PM2.5 and PM10 was significantly associated with the occurrence of AMI with and without adjustment for the temperature and humidity. In the adjusted model each 10 µg/m3 increase of PM10 and PM2.5 in case periods was significantly associated with increase myocardial infarction events (95% CI = 1.041-1.099, OR = 1.069 and 95% CI = 1.073-1.196, and OR = 1.133, respectively). Subgroup analysis showed that increase in PM10 did not increase AMI events in diabetic subgroup, but in all other subgroups PM10 and PM2 .5 concentration showed positive associations with increased AMI events. CONCLUSION: Acute exposure to ambient air pollution was associated with increased risk of AMI irrespective of temperature and humidity.

ABSTRACT

BACKGROUND: In the INSPIRATION-S trial, atorvastatin versus placebo was associated with a nonsignificant 16% reduction in 30-day composite of venous/arterial thrombosis or death in intensive care unit (ICU) patients with COVID-19. Thrombo-inflammatory response in coronavirus disease 2019 (COVID-19) may last beyond the first 30 days. METHODS: This article reports the effects of atorvastatin 20 mg daily versus placebo on 90-day clinical and functional outcomes from INSPIRATION-S, a double-blind multicenter randomized trial of adult ICU patients with COVID-19. The main outcome for this prespecified study was a composite of adjudicated venous/arterial thrombosis, treatment with extracorporeal membrane oxygenation (ECMO), or all-cause mortality. Functional status was assessed with the Post-COVID-19 Functional Scale. RESULTS: In the primary analysis, 587 patients were included (age: 57 [Q1-Q3: 45-68] years; 44% women). By 90-day follow-up, the main outcome occurred in 96 (33.1%) patients assigned to atorvastatin and 113 (38.0%) assigned to placebo (hazard ratio [HR]: 0.80, 95% confidence interval [CI]: 0.60-1.05, p = 0.11). Atorvastatin in patients who presented within 7 days of symptom onset was associated with reduced 90-day hazard for the main outcome (HR: 0.60, 95% CI: 0.42-0.86, p interaction = 0.02). Atorvastatin use was associated with improved 90-day functional status, although the upper bound CI crossed 1.0 (ORordinal: 0.64, 95% CI: 0.41-1.01, p = 0.05). CONCLUSION: Atorvastatin 20 mg compared with placebo did not significantly reduce the 90-day composite of death, treatment with ECMO, or venous/arterial thrombosis. However, the point estimates do not exclude a potential clinically meaningful treatment effect, especially among patients who presented within 7 days of symptom onset (NCT04486508).

ABSTRACT

OBJECTIVE: The aim of this study was to compare pain levels from arterial blood gas (ABG) sampling performed with or without application of lidocaine via jet injector. BACKGROUND: Pain is still a primary concern in the emergency department. Arterial blood gas sampling is a very painful procedure. No better technique for decreasing the pain of the ABG procedure has been presented. An ideal local anesthesia procedure for ABG sampling should be rapid, easily learned, inexpensive, and free of needlestick risk. MATERIALS AND METHODS: We evaluated the effectiveness of a lidocaine jet injection technique in achieving satisfactory pain control in patients undergoing ABG sampling. Forty-two patients were randomized to 2 groups: group A, which received lidocaine by jet injection (0.2 mL of lidocaine 2%), and group B, a control group that received a topical application of 1 mL of lidocaine gel 2% 2 minutes before the ABG sampling. Pain was assessed on a 10-cm visual analog scale (0, absence of pain; 10, greatest imaginable pain). RESULTS: The pain visual analog scale score during ABG sampling was considerably lower in group A compared with group B (1.29 ± 0.90 vs 4.19 ± 1.43; P < .001). The number of attempts required for ABG sampling was significantly lower in group A compared with group B (1.29 ± 0.46 vs 2.1 ± 0.12; P = .009). All residents reported ease of use with the lidocaine jet injection procedure (P < .05). CONCLUSION: Lidocaine jet injection provides beneficial and rapid anesthesia, resulting in less pain and a greater rate of successful ABG sampling. Therefore, it is recommended for use before ABG sampling to decrease the patient's pain and the number of unsuccessful attempts and to enhance the patient's satisfaction.

ABSTRACT

BACKGROUND: The Primary Percutaneous Coronary Intervention (PPCI) is the preferred therapeutic strategy for patients who experienced ST-Elevation Myocardial Infarction (STEMI). OBJECTIVE: We aimed to evaluate the association of hematological indices, including hemoglobin level, platelets, White Blood Cells (WBCs) count, and MPV before PPCI with the TIMI grade flow after PPCI. METHODS: STEMI patients who experienced PPCI were included in the present retrospective crosssectional study. Then participants were divided into three groups based on their post-procedural TIMI flow grades. Demographic data and hematologic indices of patients before PPCI were collected and their association with the TIMI grade flow after PPCI was evaluated. To compare the quantitative and qualitative variables, chi-square and t-tests were performed, respectively. RESULTS: We found that elevated levels of hemoglobin and decreased levels of MPV had a significant association with an advanced grade of TIMI flow. Interestingly, in the normal range, there was a significant association between higher platelet count and TIMI-flow grade 1. Besides, TIMI flow grades 2 and 3 had a significant association with low and moderate platelets count, respectively. CONCLUSION: In conclusion, evaluating MPV, platelets, and hemoglobin levels before PPCI as easy and accessible parameters may be able to identify high-risk STEMI patients undergoing PPCI.

ABSTRACT

INTRODUCTION: ST-elevation myocardial infarction (STEMI) is known to be associated with significant arrhythmia and consequent mortality. QT prolongation is a risk factor for arrhythmia in STEMI patients who underwent primary percutaneous coronary intervention (PPCI). The aim of this investigation was to evaluate the association of corrected QT interval (QTc), QT dispersion (QTd), T-wave peak to end (TPE), and fragmented QRS with mortality in these patients. METHODS: Eligible patients with the characteristic symptoms of STEMI who underwent PPCI were included. QTc, QTd, TPE, and fragmented QRS were measured before and after the PPCI. These predictors were compared between patients who died during hospitalization and discharged patients. RESULTS: After coronary angiography, 10 patients (4%) died during the hospitalization after PPCI. Comparing the non-survivers and discharged patients in terms of arrhythmia predictors showed that the mean QT dispersion and TPE before intervention were significantly higher in the non-survivors. Also, the number of patients who experienced fragmented QRS both before and after the intervention was significantly higher in the non-survivors. CONCLUSION: These data suggested that evaluating such arrhythmia predictors, especially before PPCI, could be used as a predictor of mortality in STEMI patients who underwent PPCI.

ABSTRACT

BACKGROUND: Thrombotic complications are considered among the main extrapulmonary manifestations of coronavirus disease 2019 (COVID-19). The optimal type and duration of prophylactic antithrombotic therapy in these patients remain unknown. METHODS: This article reports the final (90-day) results of the Intermediate versus Standard-dose Prophylactic anticoagulation In cRitically-ill pATIents with COVID-19: An opeN label randomized controlled trial (INSPIRATION) study. Patients with COVID-19 admitted to intensive care were randomized to intermediate-dose versus standard-dose prophylactic anticoagulation for 30 days, irrespective of hospital discharge status. The primary efficacy outcome was a composite of adjudicated venous or arterial thrombosis, treatment with extracorporeal membrane oxygenation (ECMO), or all-cause death. The main safety outcome was major bleeding. RESULTS: Of 600 randomized patients, 562 entered the modified intention-to-treat analysis (median age [Q1, Q3]: 62 [50, 71] years; 237 [42.2%] women), of whom 336 (59.8%) survived to hospital discharge. The primary outcome occurred in 132 (47.8%) of patients assigned to intermediate dose and 130 (45.4%) patients assigned to standard-dose prophylactic anticoagulation (hazard ratio [HR]: 1.21, 95% confidence interval [CI]: 0.95-1.55, p = 0.11). Findings were similar for other efficacy outcomes, and in the landmark analysis from days 31 to 90 (HR: 1.59, 95% CI: 0.45-5.06). There were 7 (2.5%) major bleeding events in the intermediate-dose group (including 3 fatal events) and 4 (1.4%) major bleeding events in the standard-dose group (none fatal) (HR: 1.82, 95% CI: 0.53-6.24). CONCLUSION: Intermediate-dose compared with standard-dose prophylactic anticoagulation did not reduce a composite of death, treatment with ECMO, or venous or arterial thrombosis at 90-day follow-up.
