BACKGROUND: Today, mobile phones are recognised as an inseparable part of our daily lives, facilitating communication between users. Based on the studies, addiction to cell phones can lead to several complications including depression, anxiety, anger, and aggression. AIM: This study aimed to investigate nomophobia (no mobile phone phobia) among medical students of Islamic Azad University, Tehran Branch. METHODS: This descriptive cross-sectional study was conducted on 100 students studying in different majors of medical sciences in Islamic Azad University, Tehran Branch, from 2016 to 2017. Demographic data of all participants were recorded in a data sheet. In the next stage, a questionnaire was designed by the researcher to evaluate the effect of age, gender, education, and the duration of using cell phone variables on discomfort, anxiety, and insecurity due to lack of access to cell phone or other related issues. Raw data were analysed using SPSS statistical software version 21. The significance level was considered P < 0.05. RESULTS: The results of the study showed that participants with lower mean age felt more discomfort, anger, anxiety, and insecurity due to lack of access to mobile phones and other related issues compared to other people. However, no variable was statistically significant (P-value > 0.05). Except anxiety, results showed that longer duration of mobile phone use might lead to a significant decrease in discomfort, anger, and insensibility variables among users (P-value > 0.05). The incidence of nomophobia (with its different aspects) was significantly lower in females (P-value > 0.05). Also, in participants with higher educational status, the nomophobia was recorded to be more frequent (P-Value > 0.05). CONCLUSION: Understanding the pattern of nomophobia occurrence among cell phone users can facilitate our path to prevent its harms including discomfort, anger, anxiety, and feeling of insecurity among users of technology.
Nosocomial infections or healthcare associated infections occur in patients under medical care. Infections acquired in hospitals have existed since the very inception of hospitals themselves, and continue to be an important health problem even in the modern era of antibiotics. Today, they result in high morbidity and mortality, extended hospitalization, greater use of antibiotics, and increased costs. The overuse and inappropriate consumption and application of antibiotics have driven the rapid emergence of multidrug-resistant drugs (MDR) pathogens. Combating MDRs which cause serious life threatening nosocomial infections and appear to be biologically compatible with their environment, are difficult to manage due to the limited treatment options. The worldwide emergence of multidrug resistance (MDR) among Gram negative and Grampositive bacteria has caused a great threat to fight the bacterial pathogens. It is clear that in the lack of a timely, efficient solution the challenge of antibiotic resistance becomes alarming and will cause a great challenge in the forthcoming years. In this review article we will discuss the most important MDR nosocomial infection agents, including Staphylococcus aureus, Enterococcus faecium, Klebsiella pneumoniae, Acinetobacter baumannii and Pseudomonas aeruginosa as major threats throughout the world.
This systematic review and meta-analysis was conducted to evaluate the effect of COVID-19 on thyroid function and the role of thyroid hormones alterations in predicting the severity of COVID-19. Online databases, including Scopus, Medline/PubMed, EMBASE, Google Scholar, and Cochrane were searched up to August 2, 2022. After screening titles, abstracts, and full manuscripts, respectively, 30 reports were enrolled. The risk of bias (ROB) was evaluated using the QUADAS-2 tool. In addition, odds ratio (OR) and hazard ratio (HR) analysis for assessing the OR of abnormal thyroid function tests (TFT) in predicting the COVID-19 severity and poor outcomes. Among 30 enrolled studies, ROB of the current study is estimated low to moderate. The average number of patients in each study was 325 (range: 40-3,703), with an overall mean age of 57.6, and the female proportion of 40.4%. Overall, the pooled analysis showed that the prevalence of thyroid dysfunction among 9,707 COVID-19 cases was 15%. Among mild to moderate COVID-19 patients, 6.2% had abnormal TFT, and among patients who experienced severe to critical COVID-19, 20.8% had abnormal TFT. The pooled OR for abnormal TFT and the severity of COVID-19 obtained from 3,865 COVID-19 patients was 3.77 (2.03, 6.99). The pooled HR of TSH level of COVID-19 mortality was 1.57 (0.91, 2.72). Our results demonstrate a high prevalence of thyroid dysfunction in COVID-19, and that among patients severe cases had a 3.77-fold higher risk of abnormal TFT compared to mild to moderate COVID-19. Further studies are required to evaluate the longer-term prognostic role of thyroid dysfunction in severe COVID-19, and investigate potential therapeutic strategies.
Infection due to the protozoa giardia is one of the most common parasitic infections in the world. Millions of people across the world acquire this infection each year. The most common clinical symptoms of giardiasis include abdominal pain, bloating and diarrhea, indigestion, epigastric pain, nausea, vomiting, and oily feces with bad smell. Drugs used for giardiasis lead to certain side effects, such as unpleasant taste in the mouth, gastrointestinal discomfort, nausea, headache and leukopenia. Considering the importance of giardiasis infection, it is essential to identify anti-parasitic herbal drugs to eliminate cystic and trophozoite types of this disease. Hence, this article is aimed to report the medicinal plants that are used in Iranian traditional medicine against giardiasis. The information in this review study was obtained from scientific articles indexed in databases such as ISI, PubMed, Scopus, SID, Magiran and Google Scholar that were retrieved using the search terms giardia, protozoa, herbs, extracts and essential oils. Medicinal plants such as Lavandula stoechas, Ferula assa-foetida, Tanacetum parthenium, Allium paradoxum, Chenopodium botrys, Carum copticum, Allium sativum, Artemisia annua, Allium ascalonicum, ZizIphora clinopodioides, Zataria multiflorahad, Eucalyptus globulus, Lippia beriandievi, Punica granatum are among the most important herbs used in Iranian herbal medicine as anti-giardiasis agents. These herbs are good candidates to produce natural and effective drugs for giardia.
