Spontaneous pneumothorax in a pregnant woman with COVID-19: a case report

Numerous symptoms and complications of COVID-19 include pneumothorax as a rare but potentially-lethal condition. The present case report involved a pregnant woman with COVID-19 presenting with pneumothorax. A 30-year-old pregnant woman with COVID-19 and a gestational age of 32 weeks presented to our hospital with dyspnea, coughs and fever. The rales initially heard in both lungs continued to be heard only in the left lung after 24 hours. Pneumothorax was confirmed through radiology. The emergency cesarean section performed to avoid the potential detrimental effects of the infection on the fetus caused no breathing episodes in the biophysical profile. The patient recovered postpartum without complications and both the mother and the newborn were discharged 12 days later. Spontaneous pneumothorax is a rare complication in COVID-19 pregnant patients that can emerge at any stage of the disease

Investigation of Performance Management Behaviors in Educational Managers of Iran University of Medical Sciences

Performance management supports the power of knowledge in the academic system and makes this knowledge a comparative advantage. The amount of performance management behavior expressed by managers affects their assessment and ability to improve. Therefore, the present study aims to investigate the performance management behaviors expressed by the educational managers of Iran University of Medical Sciences. This is a descriptive-analytic study. The population under study includes the educational managers of Iran University of Medical Sciences. A census was applied as the sampling method. Performance Management Behavior Questionnaire (PMBQ) was applied as the data collection instrument. After evaluating the validity and reliability of this instrument, data would be analyzed through descriptive and inferential statistical tests. Of all distributed questionnaires, 144 were filled and recollected. The obtained means were average or higher for all aspects. The average score of male and female managers was respectively equal to 89.58 and 86.77. The total average score was 83.58 with the standard deviation of 6.4224. In no aspect, the difference between average scores of male and female managers was statistically significant. As to the performance expectations, there was a significant difference in behavior of managers with different management experiences (p=0.014). According to the results, the educational managers of Iran University of Medical Sciences have all evaluated their performance management behaviors to be generally desirable

Personal, family and societal educational needs assessment of individuals with spinal cord injury in Iran

Objectives: To explore individuals’ perception of the personal, family and societal educational needs following a spinal cord injury. Methods: Sixty-one patients who sustained a traumatic SCI between March 2015 and June 2016 referred to Brain and Spinal Cord Injury Research Center were included in a cross sectional study and completed an online survey containing open-and closed-ended questions, in Iran. Participants’ responses were analyzed i using a qualitative approach with a thematic analysis. Results: Following a thematic analysis of the patient’s perceived educational needs, 3 themes and 14 subthemes were identified. The 3 themes included personal, family, and societal educational perceived needs. Within personal educational needs, there were 7 subthemes which included personal independence and transportation, financial independence, life skills modification, knowledge about SCI, prevention of SCI complications, relationships and sexual function, and psychological adjustments. Among family educational needs, the 3 subthemes were caregiver skills and communication, first aid and emergency skills, and emotional and psychological support. For societal educational needs, the 4 subthemes described were social integration, interpersonal communication skills, SCI awareness and injury prevention, sympathize while avoiding pity. Conclusion: According to our findings, people with SCI have various needs that need to be addressed. Educational support should be a part of a comprehensive rehabilitation program and geared towards addressing the patients’ personal and family needs, while educating the community about SCI in order to allow for reintegration into society

Real Exchange Rate Shocks and Export-Oriented Businesses in Iran: An Empirical Analysis Using NARDL Model

In this paper, the asymmetric and nonlinear effects of the real exchange rate shocks on different export-oriented businesses, i.e. Petrochemical, Basic Metal, and Mining industries stock indexes, in Tehran Stock Exchange is examined. From the policymakers’ perspective, this idea is theoretically interpreted as a "fear of appreciation" hypothesis that refers to the intervention of central banks in foreign exchange markets to restrict currency appreciation rather than depreciation to defend export competitiveness. To this aim, in addition to the main variables, the monthly time series data of the control variables, i.e. inflation, OPEC oil price, and international sanctions, from 2012:01 to 2020:01 are used. Our findings based on the NARDL approach illustrate that not only have exchange rate shocks significant effects on different stock indexes, but these relationships are asymmetric and nonlinear. Moreover, the results have confirmed the fear of depreciations hypothesis in the export-oriented industries, that means the central bank of Iran tends to pursue the “leaning-against-the-depreciation-wind” policy rather than “leaning-against-the-appreciation-wind” one

Inhibition of AGS cancer cell proliferation following siRNA-mediated downregulation of VEGFR2

Vascular endothelial growth factor (VEGF) and VEGF receptors (VEGFRs) play important roles in angiogenesis of different developmental mechanisms such as wound healing, embryogenesis and diseases, including different types of cancer. VEGFR2 is associated with cell proliferation, migration, and vascular permeability of endothelial cells. Blocking VEGF and its receptors is suggested as a therapeutic approach to prevent tumor growth. In this study, we aim to block VEGF signaling via small interfering RNA (siRNA) inhibition of VEGFR2. Materials and Methods: In this experimental study, we used the RNA interference (RNAi) mechanism to suppress expression of the VEGFR2 gene. We conducted the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-tetrazolium bromide (MTT) assay, real-time polymerase chain reaction (PCR), Western blot, and?ow cytometry analyses of VEGFR2 expression. Results: Real-time PCR and Western blot results showed that VEGFR2 expression signifcantly downregulated. This suppression was followed by inhibition of cell proliferation, reduction of viability, and induction of apoptosis in the cancer cells. Conclusion: These findings suggest that VEGFR2 has a role in cell proliferation and tumor growth. Accordingly, it is suggested that VEGFR2 can be a therapeutic target for controlling tumor growth and proliferation
