Abstract
Objective This study aimed to quantify the incidence of Contrast-induced nephropathy (CIN) in patients undergoing primary percutaneous coronary intervention (PPCI) due to acute ST-elevation myocardial infarction (STEMI). Methods From April 2019 to March 2022, a prospective, observational study enrolled 213 consecutive STEMI patients referred to a tertiary hospital for PPCI. Participants were divided into tow groups based on the presence or absence of contrast-induced nephropathy. The chi-square test (χ2) and Student's t-test evaluated the data, with logistic regression identifying CIN's independent predictors. Results Results: In this study, the incidence of contrast-induced nephropathy was observed at 13.1% (N = 28). Several factors were more prevalent among patients exhibiting contrast-induced nephropathy. These factors encompassed: radial access for coronary angiography over the femoral method (P = 0.021), elevated contrast volume (P = 0.003), smoking (P = 0.009), diabetes (P = 0.04), heart failure (P = 0.049), a history of coronary artery bypass graft (P = 0.006), diminished left ventricular ejection fraction indicating systolic dysfunction (P = 0.012), cardiogenic shock (P = 0.046), increased BUN at the time of admission (P = 0.043), decreased initial GFR (P = 0.004), and prior consumption of medications such as aspirin (P = 0.002), diuretics (P = 0.046), beta blockers (P = 0.04), angiotensin-converting enzyme inhibitors (P = 0.033), angiotensin receptor blockers (P = 0.02). Other relevant conditions included anemia (P = 0.012), leukocytosis (P = 0.011), hypercholesterolemia (P = 0.034), and reduced HDL levels (P = 0.004).Through logistic regression, key predictors for the onset of contrast-induced nephropathy were determined, which included heart failure (OR: 5.52; 95% CI: 1.08-28.24), radial access (OR: 12.71; 95% CI: 1.45-110.9), hypercholesterolemia (OR: 1.02; 95% CI: 1.004-1.04), increased BUN upon admission (OR: 1.11; 95% CI: 1.006-1.24), and leukocytosis (OR: 2.03; 95% CI: 1.18-3.49). Conclusions While heart failure, radial access, hypercholesterolemia, elevated BUN at admission, and leukocytosis significantly influenced renal filtration deterioration post-PPCI, it's evident that CIN is multifactorial. Further studies are crucial to elucidate the underlying factors.

Abstract
We demonstrate the trapping of millimeter-scale superfluid helium drops in high vacuum. The drops are sufficiently isolated that they remain trapped indefinitely, cool by evaporation to 330 mK, and exhibit mechanical damping that is limited by internal processes. The drops are also shown to host optical whispering gallery modes. The approach described here combines the advantages of multiple techniques, and should offer access to new experimental regimes of cold chemistry, superfluid physics, and optomechanics.

Abstract
BACKGROUND Inflammatory rheumatic diseases, including systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), and systemic sclerosis (SSc), can cause cardiovascular complications in many cases. This study aimed to compare the ventricular and atrial functions of the heart between rheumatic patients and healthy controls using transthoracic echocardiography (TTE). RESULTS The study was performed between 64 patients with mentioned rheumatic diseases and 64 age- and sex-matched healthy controls who all underwent detailed history-taking and TTE. Echocardiographic parameters were measured and compared between the two groups. TTE showed significant differences in many echocardiographic parameters. Left ventricular end-diastolic diameter, left ventricular end-systolic diameter, right atrium area, inferior vena cava diameter, and systolic pulmonary artery pressure were significantly higher in patients compared to the controls (P < 0.001). Left ventricular ejection fraction and right ventricular end-diastolic diameter were not statistically different between the groups (P > 0.05). Right ventricular septal strain, right ventricular free wall strain, average longitudinal right ventricular strain, tricuspid annular plane systolic excursion, right ventricular systolic myocardial velocity, and right ventricular fractional area change were lower in inflammatory rheumatic patients (P < 0.001). The subgroup analysis showed the same results' trend for each disease and its own control group comparison. CONCLUSIONS Cardiac involvement in rheumatologic diseases, especially SLE, RA, and SSc, should always be taken into consideration as there may be silent changes affecting the overall prognosis of patients. Using TTE helps diagnose and make a treatment plan for cardiovascular complications in rheumatic disease patients.

Abstract
Background: Behcet’s disease (BD) is a vasculitis with multisystem and multiorgan involvement. Cardiac involvement in BD is a rare complication with a poor outcome that manifests itself in different forms. In this study, we aimed to investigate cardiac involvement in BD. Methods: This is a retrospective study based on cardiac manifestations in BD according to the data of the Behçet’s Disease Unit, the Rheumatology Research Center, Tehran University of Medical Sciences, from registered patients from 1975 until June 2017. Cardiac manifestations consisted of pericarditis, myocardiopathy, myocardial infarction, stable ischemic heart disease, endomyocardial fibrosis, thrombosis, and valvular and coronary involvement. All the patients’ baseline and demographic data were recorded in a designed questionnaire. The laboratory workups, imaging, and pathological tests were also performed. Results: We studied 7650 patients with BD, of whom 51% were male. In the entire study population, 47 patients manifested cardiac involvement: valvular involvement in 6.1%, myocardial infarction in 23.4%, stable ischemic heart disease in 20%, pericarditis in 21.3%, intracardiac thrombosis in 2.1%, coronary aneurysm in 2.1%, heart failure in 12.8%, and dilated cardiomyopathy in 4.3%. Conclusion: The prevalence of cardiac involvement in our patients with BD was 0.6%. A multidisciplinary approach can reduce mortality and morbidity rates. Consequently, we suggest that echocardiography and other cardiac diagnostic tests be routinely considered for early diagnosis and subsequent treatment.

Abstract
Coronavirus disease 2019 (COVID-19) poses a substantial challenge for rheumatologists and rheumatologic patients. They are concerned about the reciprocal interaction between connective tissue diseases, such as systemic lupus erythematosus (SLE), and the virus. Here, we report a 21-year-old female SLE patient presented to the emergency department with gastrointestinal symptoms and kidney involvement evidence. Based on the pathology and laboratory assessments, she was suspected of C-antineutrophil cytoplasmic antibody (ANCA) positive SLE and ANCA-associated vasculitis overlap syndrome (SLE/AAV OS), and plasmapheresis was performed every other day due to this diagnosis alongside the high titer of C-ANCA. We also administered methylprednisolone [1 g/day, intravenous (IV)] for 3 days, followed by dexamethasone with the maintenance dosage (1 mg/kg/day, IV). Although the patient's general condition improved the next days, her condition deteriorated suddenly on the 7th day of hospitalisation. She got intubated and went to the intensive care unit. Despite taking possible measures to manage the patient's condition, she eventually passed away due to severe acute respiratory distress syndrome, triggered by COVID-19. The distinct role of C-ANCA in SLE/AAV vascular damage and activating neutrophil cytokine release accompanied by the impaired immune system while facing COVID-19 seems to lead to increased morbidity and mortality in such patients. This report is presented to bring into consideration the possible role of C-ANCA in the prognosis of COVID-19 in SLE/AAV OS patients.

Abstract
Digital nerve block is one of the multimodal analgesia methods used in finger trauma cases. According to some studies, dexamethasone needs further investigation before being used routinely. We therefore investigated dexamethasone's effect on the parameters of digital nerve block. In this double-blind clinical study, 60 patients were allocated to two groups: lidocaine alone and lidocaine + dexamethasone. Groups were compared for pain intensity, analgesia duration and demographic characteristics. Patients in the intervention group received 3 cc 2% lidocaine + 1 cc (equivalent to 4 mg) dexamethasone and patients in the control group received 3 cc lidocaine 2% + 1 cc normal saline. The two groups were comparable for age and gender. In the lidocaine + dexamethasone group, postoperative pain severity was significantly lower and the pain-free period was longer (P < 0.05). Dexamethasone as an adjuvant in digital nerve block after trauma reduced the severity of postoperative pain and increased the pain-free period.

Abstract
BACKGROUND We examined the safety and efficacy of a treatment protocol containing Favipiravir for the treatment of SARS-CoV-2. METHODS We did a multicenter randomized open-labeled clinical trial on moderate to severe cases infections of SARS-CoV-2. Patients with typical ground glass appearance on chest computerized tomography scan (CT scan) and oxygen saturation (SpO2) of less than 93% were enrolled. They were randomly allocated into Favipiravir (1.6 gr loading, 1.8 gr daily) and Lopinavir/Ritonavir (800/200 mg daily) treatment regimens in addition to standard care. In-hospital mortality, ICU admission, intubation, time to clinical recovery, changes in daily SpO2 after 5 min discontinuation of supplemental oxygen, and length of hospital stay were quantified and compared in the two groups. RESULTS 380 patients were randomly allocated into Favipiravir (193) and Lopinavir/Ritonavir (187) groups in 13 centers. The number of deaths, intubations, and ICU admissions were not significantly different (26, 27, 31 and 21, 17, 25 respectively). Mean hospital stay was also not different (7.9 days [SD = 6] in the Favipiravir and 8.1 [SD = 6.5] days in Lopinavir/Ritonavir groups) (p = 0.61). Time to clinical recovery in the Favipiravir group was similar to Lopinavir/Ritonavir group (HR = 0.94, 95% CI 0.75 - 1.17) and likewise the changes in the daily SpO2 after discontinuation of supplemental oxygen (p = 0.46) CONCLUSION: Adding Favipiravir to the treatment protocol did not reduce the number of ICU admissions or intubations or In-hospital mortality compared to Lopinavir/Ritonavir regimen. It also did not shorten time to clinical recovery and length of hospital stay.

Abstract
BACKGROUND Escherichia coli and Klebsiella pneumoniae are common human pathogens that cause a wide spectrum of infections. Antimicrobial resistance is a basic obstacle in the management of these infections which has different patterns in various regions. OBJECTIVES In this study, the antibiotic resistance patterns and risk factors for multidrug-resistant (MDR) E. coli and K. pneumoniae were determined. PATIENTS AND METHODS In this cross-sectional study, a total of 250 isolates (134 E. coli and 116 K. pneumoniae) were collected and antimicrobial resistances to ampicillin, amoxicillin-clavulanic acid, amikacin, gentamycin, ceftriaxone, ceftazidime, ciprofloxacin and imipenem were evaluated by disc diffusion method and confirmed by E-test. Moreover, risk factors for MDR E. coli and K. pneumoniae were also detected. RESULTS The mean ages of the culture-positive cases of E. coli and K. pneumoniae were 33.39 ± 24.42 and 36.54 ± 24.66 years, respectively (P = 0.31); 137 (54.8%) cases were male and 113 (45.2%) were female (P = 0.53). Nineteen (14.2%) isolates of E. coli and 12 (10.3%) isolates of K. pneumoniae were sensitive to all the evaluated antibiotics. The prevalence of MDR E. coli and MDR K. pneumoniae was 50% and 46.6%, respectively (P = 0.59). The highest resistance for both strains was to ampicillin and no imipenem resistance was seen. The risk factors for MDR E. coli were admission history during the recent three months (P = 0.043) and antibiotic use in the previous month (P = 0.03); for MDR K. pneumoniae, they were admission in the pediatric ward (P = 0.016), surgical ward (P = 0.019), or gynecology ward (P = 0.12), admission duration of > seven days, and antibiotic use during the past month (P = 0.04). CONCLUSIONS The prevalence of multidrug resistance was high compared with developed countries, and history of admission, antibiotic use, admission duration and admission wards were the risk factors for multidrug resistance.

Abstract
Background: Nasal colonization of healthy children with Staphylococcus aureus is an important risk factor for different infections. Detection of colonized individuals with methicillin resistant S. aureus (MRSA) and its eradication is the proper prevention strategy for infection spread in the community and health-care centers. Objectives: The aim of this study was to determine the prevalence, associated risk factors and antibiotic resistance pattern among healthy children who were nasal carriers of S. aureus. Patients and Methods: This cross-sectional study was conducted on 350 one month to 14-year-old healthy children living in Kashan/Iran. The nasal specimens were cultured in blood agar medium for S. aureus. Positive cultures were evaluated for cephalothin, co-trimoxazole, clindamycin, ciprofloxacin, oxacillin and vancomycin susceptibility by the disc diffusion method and E-test. Risk factors for nasal carriage of S. aureus and MRSA were evaluated. Results: Frequency of S. aureus nasal carriage was 92 from 350 cases (26.2%), amongst which 33 (35.9%) were MRSA. Isolates indicated an overall resistance of 52.2% to cephalothin, 33.7% to co-trimoxazol, 26.1% to ciprofloxacin, 26.1% to clindamycin, 35.9% to oxacillin and 4.3% to vancomycin. Factors associated with MRSA nasal carriage included gender (P value 0.001), age of less than four years (P value 0.016), number of individuals in the family (P value < 0.001), antibiotic use (P value < 0.001) and admission (P value < 0.001) during the previous three months, parental smoking (P value < 0.001) and sleeping with parents (P value 0.022). Conclusions: Age of less than four years, male sex, family size being more than four, antibiotic use and admission during the previous three months, parental smoking and sleeping with parents were independent risk factors for nasal colonization with MRSA.
