Objectives: This study was performed to assess the prevalence of carbapenem-resistant gram-negative bacilli which produce carbapenemase, in Loghman Hakim hospital, Tehran. Patients and Methods: In this cross-sectional study, antibiotic resistance of 300 samples of gram-negative bacilli from different patients was evaluated; 145 of which were identified as carbapenem-resistant. Carbapenemase enzyme production in these samples was assessed by the modified carbapenem inactivation method (mCIM). Results: About 81% of the samples were collected from the intensive care unit. In terms of sample type, most samples were obtained from trachea and urine culture. Acinetobacter baumannii (43%) was the most common carbapenem-resistant strain. Klebsiella pneumoniae (38%) and Pseudomonas aeruginosa (11%) ranked as the second and third most common strains, respectively. Based on mCIM evaluation, 82% of carbapenem resistance was due to the presence of carbapenemase enzyme which showed no significant difference neither between the both genders nor in various sample types. However, among carbapenemase-resistant bacilli, the presence of carbapenemase enzyme was significantly higher in A. baumannii (92%) and Escherichia coli (80%) and also in patients older than 50 years old. Conclusion: The findings of the present study showed that half of the collected gram-negative bacilli were resistant to carbapenem, of which 82% was due to the carbapenemase enzyme. The presence of the carbapenemase enzyme was higher in older patients as well as in Acinetobacter baumannii and Escherichia coli strains.","PeriodicalId":13454,"journal":{"name":"Immunopathologia Persa","volume":" ","pages":""},"PeriodicalIF":0.8,"publicationDate":"2022-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44371187","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Objectives: This study aimed to compare the cytological and histological findings in endometrial specimens among women with AUB in three different menstrual groups (pre-menopause, perimenopause, and post-menopause) and to evaluate the statistical accuracy of cytology compared to histopathology (gold standard). Patients and Methods: This descriptive study was conducted on 78 women with AUB admitted to the gynecology and obstetrics unit of Shahid Beheshti hospital, Isfahan, Iran from 2018 to 2020. Patients were divided into three groups (pre-menopause, perimenopause, and post-menopause) based on their menstrual condition. Samples were obtained using endometrial curettage and cytobrush and were analyzed by two surgical pathologists. The results were described in four categories: negative, atypical endometrial cells of undetermined significance (AEC-US), atypical endometrial cells encompassing the spectrum of precursors to the malignant endometrial tumor (AEC-PEMT), and positive. Results: Out of 78 samples, 36 (46.2%) were reported negative for epithelial abnormality, 15 (19.2%) were AEC-US, 9 (11.5%) were AEC-PEMT, and 18 (23.1%) were positive for epithelial lesions. There was a significant association between cytological findings and menstrual groups (P = 0.004). Positive results were more frequently reported in the post-menopausal group, whereas negative results were most common in the pre-menopause group. The sensitivity and specificity of cytological evaluation in the pre-menopause, perimenopause and post-menopause groups were 100% and 95% (accuracy: 100%, 95% CI: 0.94-1), 77% and 53%, (accuracy: 62%, 95% CI: 0.40-0.85), and 100% and 34% (accuracy: 41%, 95% CI: 0.20-0.61), respectively.

However, the Omicron is still detectable via previous polymerase chain reaction (PCR) tests. Clinical presentation of the disease is identical to previous VoCs, however in vitro and in vivo studies revealed a higher transmission rate. The biggest obstacles posed by Omicron are the immune escape and reduction in vaccine effectiveness, as indicated by many simulations and real-world studies. Although the efficacy of the two-dose vaccinations is suboptimal for Omicron, preliminary studies have considered the injection of a booster shot is beneficial and can decrease the risk of severe disease. All these new features of Omicron warranted close investigation of this VoC as a new chapter in the pandemic, especially with emersion of subvariants BA.4 and BA.5.

Objectives: The aim of this study was to evaluate the effect of 10-week aerobic exercise on cardiac function among overweight female breast cancer survivors. Patients and Methods: This triple-blinded randomized clinical trial was carried out among 25 overweight female breast cancer survivors (age range; 30-55 years). The aerobic exercise training protocol was performed for 10 weeks with an intensity of 40 to 75% of maximal heart rate. Anthropometric parameters and body composition of patients were measured (pre-test/post-test design). Echocardiography was used to determine the ejection fraction and pulmonary artery pressure of the patients too. Results: There was no significant difference between anthropometric parameters and body composition of patients in the control and exercise groups. Additionally, there was a significant difference in the ejection fraction (P=0.001), PAP (P = 0.025) and VO2max between patients of control and exercise groups (P=0.001). Conclusion: A 10-week aerobic exercise leads to an increase in the levels of VO2max, ejection fraction and pulmonary arterial pressure.

Objectives: The aim of this study was to determine antimicrobial susceptibility of meropenem against Acinetobacter and Klebsiella strains in samples obtained from hospitalized patients with ventilator-associated pneumonia (VAP). Patients and Methods: In this cross-sectional study, 100 patients with VAP were selected from the intensive care unit (ICU) of Amin hospital in Isfahan. Lung secretions were collected and tested for bacterial infections. In samples with the positive bacterial infection, E-test and agar diffusion test were used to determine and compare the susceptibility of Acinetobacter and Klebsiella strains to meropenem. Results: The two susceptibility testing methods – E-test and agar diffusion test – showed similar results in 87 cases (87%) therefore, 84 cases were resistant and three cases were susceptible to meropenem. However, in 13 cases, the result of the agar diffusion test was resistant and the result of E-test was sensitive. According to the Kappa test, the agreement between the two tests was 0.87 and statistically significant (P <0.001). Conclusion: Due to the high resistance of Klebsiella and Acinetobacter strains to meropenem, it should not be used as an experimental treatment in patients diagnosed with VAP caused by these strains. We recommend using meropenem for Acinetobacter and Klebsiella after susceptibility testing by E-test confirmed its efficacy.","PeriodicalId":13454,"journal":{"name":"Immunopathologia Persa","volume":" ","pages":""},"PeriodicalIF":0.8,"publicationDate":"2022-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42555766","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Magnetic resonance imaging (MRI) – as the gold standard of shoulder imaging- plays a critical role in diagnosis of adhesive capsulitis, in the early stages. The anterior predominance of pathologic and arthroscopic abnormalities suggest that the thickness of anterior joint capsule may be a more reliable diagnostic criterion on MRI; however, to our knowledge, only one study has evaluated the significance of this parameter up to now, the results of which, may be subject to substantial bias, due to small sample size. Objectives: To evaluate the anterior capsule of glenohumeral joint, in terms of thickness and signal intensity, and also to conduct a comparison between adhesive capsulitis subjects and control individuals. Materials and Methods: This is a case-control study. Cases were all patients with the final diagnosis of adhesive capsulitis, based on history, physical examination and imaging. Controls were all patients who underwent shoulder MRI, because of another reason. Anterior capsular thickness, and other qualitative and quantitative criteria were evaluated on the MRIs, by two musculoskeletal radiologists, with three and 10 years experience respectively. Results: All of the evaluated criteria showed significant difference, between cases and controls. Considering the cut-off point equal to 1.3 mm, \"anterior capsular thickness\" had 86.7% sensitivity, 96.7% specificity, 96.3% positive and 87.9% negative predictive values respectively, which posed an acceptable position among MRI criteria of adhesive capsulitis. Of note, was the near perfect inter-observer agreement of this criterion between the two radiologists, implicating its practicality. Conclusion: The anterior capsule signal and thickness are valuable criteria for diagnosis of adhesive capsulitis on MRI. Future studies with large sample volumes, clinical sub-categorization of the patients and multivariate analysis are recommended to more accurately define its role in MRI-based diagnosis of adhesive capsulitis.","PeriodicalId":13454,"journal":{"name":"Immunopathologia Persa","volume":" ","pages":""},"PeriodicalIF":0.8,"publicationDate":"2022-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45748429","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The maxillary sinuses are important for dentist because of their location. The volume of them can be affected by various factors and make them prone to sinusitis. Objectives: This retrospective study examined maxillary sinus volume in relationship with nasal septum deviation (NSD) by using cone-beam computed tomography (CBCT). Materials and Methods: From our CBCT archives, we retrospectively selected 210 CBCT images and 420 healthy maxillary sinuses. The maxillary sinuses were calculated using the NNT Viewer software by importing CBCT images. In this study, NSDs were classified into three levels of severity: mild, moderate, and severe. In patients with NSD, bilateral sinus volumes were compared and allowed us to determine the difference in maxillary sinus volume. Statistical analysis was conducted using SPSS (P<0.05). Results: The average volume of the right and left maxillary sinuses is 13.04 ± 3.37 cm3 and 13.59 ± 3.33 cm3 , respectively. The prevalence of NSD in population of this study was 89.5%. Both sides of the maxillary sinuses were significantly larger in male patients than female patients (P<0.05). The negative correlation between age and maxillary sinus volume (P<0.05) showed that maxillary sinus volume decreased with age. For cases of moderate and severe NSDs in the same direction as the deviation, the maxillary sinus volume is significantly smaller than that on the opposite side (P<0.05), while there was no significant difference in mild cases of deviation (P>0.05). Conclusion: In moderate and severe groups, maxillary sinus volume was smaller on the same side compared with the opposite side of deviation, and maxillary sinus volume is greater in male patients than female patients, and it decreases with age.","PeriodicalId":13454,"journal":{"name":"Immunopathologia Persa","volume":" ","pages":""},"PeriodicalIF":0.8,"publicationDate":"2022-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44126492","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
