In the present study, we compared the preventative and therapeutic strategies and the success rates of Iran and Switzerland during the COVID-19 outbreak.<br><strong>Materials and Methods:</strong> This study was conducted using electronic databases such as PubMed, Scopus, and<br>Web of Science. In addition, the official documents of developed countries and WHO from 1st February until 15th May 2020 were studied. Relevant documents were reviewed in detail, and vital data were extracted.<br><strong>Results</strong>: Both countries have restriction policies to reduce the infection rate in the prevention setting. These<br>policies, such as the recommendation to all citizens to stay home unless necessary, army participation, and<br>non-face-to-face counseling, were surveyed by similar techniques in both countries. Some policies were<br>implemented in both countries with different protocols. These policies, including social distancing practices,<br>smart distancing methods, business activities, border closures, border controls, and restrictions, travel<br>restrictions, testing and screening for infection and fever, and decreased working hours, were performed in<br>both countries. In the treatment setting, the therapeutic strategy used in Iran consisted of hydroxychloroquine<br>or chloroquine phosphate and anti-viral drugs. Switzerland followed the guidelines of the European countries.<br>The infection rate, recovery rate, and death rate were 0.139%, 78.73%, and 5.91% in Iran, while these rates<br>were 0.352%, 88.81%, and 6.15% in Switzerland, respectively.<br><strong>Conclusion</strong>: Due to the lack of special treatment for the disease, prevention must be considered the most<br>important factor in policymaking. Importantly, observing social distance is the most effective method among<br>the preventative strategies. The capacity of the health care systems to provide optimal services and facilities is<br>an important factor for patients recovery.</p> Payam Peymani, Somaye Bazdar, Leila Zarei, Mehdi Hoorang, Nazafarin Hatami-Mazinani, Kamran B Lankarani, Ali Reza Salili, Fatemeh Dehghani, Farshad Bargrizaneh, Sara Moghaddam, Maryam Matouri, Shima Jafari, Seyyed Amirreza Saghi, Hamed Delam, Motahareh Mahi-Birjand Copyright (c) 2022 Novelty in Biomedicine https://journals.sbmu.ac.ir/nbm/article/view/38215 Fri, 02 Dec 2022 00:00:00 +0000 Impact of educational interventions on the prevention of emerging diseases: A systematic review https://journals.sbmu.ac.ir/nbm/article/view/38571 <p><span class="fontstyle0"><strong>Background</strong>: </span><span class="fontstyle2">Seasonal influenza and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) could<br>cause considerable morbidity and mortality.

Due to<br>developing countries' difficulties, PCR is limited in Iran. This study seeks to determine the feasibility of early<br>low-dose chest computed tomography (CT) scans substitution with PCR.<br><strong>Materials and Methods</strong>: Asymptomatic participants with a history of close contact with a confirmed case of<br>COVID-19 were enrolled and followed for one week, receiving 2 PCR tests within one week. Initially, a chest<br>CT scan was performed. The second CT scan was performed within one week on two participants. Participants<br>with an initially negative CT scan and participants with a first CT scan compatible with COVID-19 who became<br>symptomatic.<br><strong>Results</strong>: All Participants had an RT-PCR and at least one CT scan. Positive RT-PCR results were reported in<br>6 and 9 participants initially and within one week, respectively. Chest CT scans favoring COVID-19 infection<br>were initially reported in 4 and 6 participants within one week, respectively. Seventeen participants showed<br>neither symptoms nor positive RT-PCR or chested CT scans favoring COVID-19. Thirteen participants either<br>had positive RT-PCR, a COVID-19 chest CT scan or became symptomatic.<br><strong>Conclusion</strong>: Rapid detection of COVID-19 and subsequent quarantining is crucial in the global fight against<br>this pandemic. Our results showed lower sensitivity for chest CT scans compared to COVID-19 PCR,<br>suggesting that chest CT scans are unsuitable for COVID-19 PCR tests.</p> Hooman Bahrami-Motlagh, Amir Mohammad Papan, Zahra Sahraei, Babak Salevatipour, Maryam Haghighimorad, Alireza Karami, Mana Zaman, Rastin Radfar, Minoosh Shabani Copyright (c) 2022 Novelty in Biomedicine https://journals.sbmu.ac.ir/nbm/article/view/37938 Fri, 02 Dec 2022 19:28:40 +0000 A Randomized Controlled Trial: Colistin Alone or Colistin and Meropenem: Which Is More Effective for the Management of Urinary Tract Infections? https://journals.sbmu.ac.ir/nbm/article/view/38197 <p><span class="fontstyle0">Background: </span><span class="fontstyle2">Colistin is a common antibiotic used to treat urinary tract infections (UTIs) caused by gramnegative bacteria. In recent years, due to the increasing resistance, consumption of colistin alone could lead to<br>treatment failures. This study aimed to compare the effectiveness of colistin alone with colistin and meropenem<br>to treat patients with urinary tract infections.<br></span><span class="fontstyle0">Materials and Methods: </span><span class="fontstyle2">In this randomized, open-label, parallel groups controlled trial, hospitalized patients<br>with urinary tract infections were included. Patients were randomly allocated to the control group (n=35) that<br>received colistin (1 mIU every 12 hours) and the intervention group (n=35) that received colistin (1 mIU every<br>12 hours) with meropenem (1gr every 8 hours). An infectious disease specialist evaluated the therapeutic<br>responses 48-72 hours after admission. Cessation of fever, improvement of symptoms and signs, and negative<br>urine culture within 48 hours were considered successful therapeutic responses.<br></span><span class="fontstyle0">Results: </span><span class="fontstyle2">The mean length of hospitalization was longer in the control group (4.74±0.78 days) compared with<br>the intervention group (4.26±0.56 days) (P=0.004). The prevalence of fever cessation had no significant<br>difference between the two groups at any time (P&gt;0.05). Also, there was no significant difference between<br>the two groups at any time, considering vital signs, irritative urinary symptoms, nausea and vomiting, and<br>flank pain (P&gt;0.05).<br></span><span class="fontstyle0">Conclusion: </span><span class="fontstyle2">The administration of colistin and meropenem to treat UTIs was associated with a shorter<br>length of hospital stay. However, regarding response to treatment, it did not matter if they were treated with<br>colistin alone or with combination therapy (colistin and meropenem)</span> </p> Davood Yadegarynia, Shabnam Tehrani, Amirreza Keyvanfar, Latif Gachkar, Behnaz Najafi Copyright (c) 2022 Novelty in Biomedicine https://journals.sbmu.ac.ir/nbm/article/view/38197 Fri, 02 Dec 2022 19:29:57 +0000 SARS-CoV-2 IgG and IgM Analysis in Patients Who Attended a University Hospital During the COVID-19 Epidemic in Iran https://journals.sbmu.ac.ir/nbm/article/view/38313 <p><span class="fontstyle0"><strong>Background</strong>: </span><span class="fontstyle2">The world is facing a new coronavirus that causes a respiratory infection called COVID-19.<br>Therefore, there is an increasing request for antibody tests in recovered individuals since they want to evaluate<br>their immunity against SARS-CoV-2 reinfection.<br></span><span class="fontstyle0"><strong>Materials and Methods</strong>: </span><span class="fontstyle2">In our study, we had 1000 blood samples from patients admitted to the Ghiassi Hospital,<br>Tehran, Iran, or were asked to perform serological SARS-COV-2 IgM and IgG tests by their physicians were<br>collected.
