SARS-CoV-2 in domestic cats (Felis catus) in the northwest of Iran: Evidence for SARS-CoV-2 circulating between human and cats.

This study aimed to investigate the prevalence of COVID-19 in domestic cats, focusing on the disease in the northwest of Iran and then showing the natural transmission of SARS-COV-2 circulating between domestic cats and humans. After receiving ethic codes from Tehran University of Medical Sciences (IR.TUMS.VCR.REC.1399.303) and confirmed by the Center of Communicable Diseases Control (CDC) of Iran, 124 domestic cats were collected from the homes and only one hospital of Meshkin -Shahr district from northwestern Iran where SARS-CoV-2 patients were hospitalized and quarantined during 2020. Samples were prepared from fluid materials of oropharynx and nasopharynx. All samples were tested by real-time PCR (RT-PCR) using specific genes N and ORF1ab in Pasteur Institute of Iran, and then partial sequence analyses of S gene were performed. All collected cats were kept in separated cages until SARS-COV-2 infection was confirmed with the RT-PCR. RT- PCR Ct values of 123 collected cats were ≥40; thus, all of them showed negative results, but one of the collected cats with close contact with its owner, whom confirmed SARS-CoV-2 showed positive results with gene N(Ct=30) and gene ORF1ab (Ct=32). Furthermore, the positive pet cat showed respiratory and gastro-intestinal clinical manifestations, and its owner was infected with SARS-CoV-2 two weeks ago. Cats are susceptible animals to SARS-CoV-2 infection. Epidemiological evidence showed that SARS-COV-2 is able to transmit to healthy cats due to having close contact with its owner as a reverse zoonosis.

The impact of generic form of Clopidogrel on cardiovascular events in patients with coronary artery stent: results of the OPCES study.

BACKGROUND: To compare the early and late cardiovascular events as well as side effects of Osvix, a generic form of Clopidogrel versus Plavix regimens in patients with chronic stable angina, undergoing bare metal stent (BMS) or drug eluting stent (DES) placement, this study was carried out. METHODS: A total of 442 patients with chronic stable angina who were scheduled for elective percutaneous coronary intervention (PCI) were included in a randomized, double blind, multi-centric clinical trial being performed in 6 distinct university hospitals in 5 cities of Iran from March 2007 to November 2009. Baseline, demographic and history of risk factors were recorded using the patients' medical charts. Stenting procedure was performed via transfemoral approach using low osmolar contrast agents. Patients underwent BMS or DES placements based on the physician selection and were randomly assigned to Osvix or Plavix groups. Patients were followed by telephone in 0 and 6 months intervals regarding the major adverse cardiovascular events (MACE) including death, myocardial infarction, in-stent thrombosis, stroke, target lesion revascularization, and target vascular revascularization. Angina episodes, bleeding, liver enzymes, neutrophils and platelets count were also assessed in these intervals. RESULTS: There was not any significant difference between these two groups regarding the baseline characteristics. In the DES group, the 6-month mortality rate and the incidence of MACE in Osvix and Plavix groups were 0.9% and 1.9% (p = 0.61) and 1.8% and 4.9% (p = 0.26), respectively. During the follow up period after DES or BMS placement, there wasn't any significant difference regarding neutrophil and platelet counts or liver enzymes between study groups. CONCLUSIONS: Using Osvix and Plavix are followed by similar major cardiovascular events and side-effect profile in patients undergoing PCI.

Psychiatric disorders (Axis I and Axis II) and self-immolation: a case-control study from Iran.

The objective of this study was to investigate preexisting psychiatric disorders in self-immolation patients. In a case-control study, 30 consecutive cases of deliberate self-inflicted burns, admitted to the regional burn center, were compared with 30 controls. Mental disorders were assessed via detailed clinical interview. Descriptive data revealed that 67% of self-immolation patients had adjustment disorder (all female), 10% drug and alcohol abuse/dependence (all male), 7% dysthymia, 3% major depression, 3% anorexia nervosa, 3% primary insomnia, 7% borderline personality disorder (50% male), 7% depressive personality disorder (100% female), and 3% antisocial personality disorder. In bivariate comparisons, adjustment disorders emerged as related to risk of self-immolation (odds ratio = 13.00). This study suggests that adjustment disorder is a risk factor for self-immolation. As a result, it has been suggested that increasing education about problem-solving approaches, and coping skills for females and at-risk groups are appropriate prevention programs and strategies in Iranian communities.

How do examiners and examinees think about role-playing of standardized patients in an OSCE setting?

OBJECTIVE: The use of standardized patients in Objective Structured Clinical Examinations in the assessment of psychiatric residents has increased in recent years. The aim of this study is to investigate the experience of psychiatry residents and examiners with standardized patients in Iran. METHOD: Final-year residents in psychiatry participated in this study. Experienced examiners were asked to complete a questionnaire concerning the ability of standardized patients to realistically portray psychiatric patients. RESULTS: Standardized patients can convincingly portray psychiatric disorders and act according to the requested complex scenarios. CONCLUSIONS: According to these findings, the authors recommend the use of standardized patients in OSCEs for psychiatric board certification exams.

Serum Levels of TNF-, IL-6, and Selenium in Patients with Acute and Chronic Coronary Artery Disease.

BACKGROUND: Selenium (Se) is part of the glutathione peroxidase enzyme complex (GSH-PX) that plays an important role in antioxidant mechanisms in body, also it has been demonstrated that populations with low Se intake have 2-3 times greater risk of ischemic heart disease. OBJECTIVE: To determine the circulating levels of IL- 6, TNF-alpha, Cu, Zn, and Se in patients with chronic coronary artery disease (CCAD), acute myocardial infarction (AMI), and normal individuals. METHODS: Patients were divided into two groups: 25 subjects with CCAD and 25 patients with AMI. The control group included 50 normal individuals who did not have any history of ischemic heart disease, and were sex and age matched with the patients. Blood samples were collected during the first hours after the onset of chest pain in AMI group. Serum concentration of Se, Cu, and Zn were determined by atomic absorption spectrometry and TNF-alpha and IL-6 levels were measured using ELISA method. RESULTS: In both groups of patients there was a significant reduction in serum Se levels (82.36 + 11.31 g/L in CCAD, 74.08+11.31g/L in AMI, and 105+32.52g/L in the control group, p=0.03). TNF-alpha titers were increased in AMI patients compared with CCAD and control group. Mean TNF-alpha levels were 37.44 pg/ml in CCAD, 914.32 pg/ml in AMI, and 4.80 pg/ml in the control group (p=0.01). Serum levels of IL-6 in CCAD and AMI patients were 3.28 15.55 pg/ml and 472207.88 pg/ml, respectively, and 1.28 pg/ml in the control group (p=0.001). CONCLUSION: These findings confirm previous studies and demonstrate that patients suffering from AMI exhibit lower plasma concentrations of Se and higher concentrations of pro-inflammatory cytokines of TNF-alpha and IL-6.
