Factors contributing to the burnout of the faculties of a medical university in Iran: A cross‐sectional study
Background and aims: Faculty members confront a variety of obstacles over time, the most recent of which is the coronavirus disease 2019 pandemic, which may increase their vulnerability to burnout (BO). This study aims to examine BO in medical school faculties, as well as the factors that lead to BO and well‐being in them. Methods: This cross‐sectional study was conducted in 2021 using online questionnaires completed by 222 faculty members of a medical university in Iran. The Maslach Burnout Inventory‐Human Services Survey (MBI‐HSS) and the Well‐being index (WBI) were used. Additionally, we gathered individual‐level profiles (demographic, well‐being) and occupational information (job profile, attitude toward work). Results: A total of 60 (27%) faculties reported having high BO, and 112 (50.5%) reported having low well‐being. Being female (odds ratio, OR = 2.69), having time to spend with the family (OR = .26), the intent of turnover (OR = 8.65), job recommendation to the offspring (OR = .26), and experiencing violence last year (OR = 2.97) were some of the individual‐level factors and job‐related attitudes associated with a higher BO. In the neural network for BO, the most important variables were the intention of turnover, followed by adequate family time. Conclusion: One third of the responding faculty reported severe BO, and BO was found to be significantly associated with lower well‐being. The increased levels of BO and a decreased experience of well‐being were both associated with a higher intention of turnover. According to the study, it is important to pay attention to both clinical and nonclinical field faculty members, female faculty members, those who have a high workload, and members who have experienced violence in the workplace. By acknowledging the unique challenges and experiences faced by these individuals, tailored measures can be developed to address their specific concerns and foster a supportive and inclusive environment
Serologic evidence of pertussis infection in vaccinated Iranian children
Background: It seems that the incidence of pertussis-like illnesses is considerably increasing despite the wide coverage of immunization with the whole cell pertussis vaccine. We aimed to investigate the occurrence of pertussis in vaccinated children by measuring anti-pertussis antibodies. Methods: In this cross-sectional study, blood samples were taken from vaccinated children aged 2, 4, 6, 12, 18, and 72 months. Anti-pertussis IgG and IgA were measured by ELISA. P<0.05 was considered significant. Results: 725 children were enrolled in the study. Geometric mean titers for IgG that showed a slight decease after 2 months of age and increased distinctly in children aged 72 months. The frequency of the individuals whose IgG was above the determined cut-off (derived from mean+2SD) was observed in 1 of the 2, 4, and 6-month-old infants, 6 of the 12 and 18-month-olds and 12 of the 6-year -old children. Positive IgA titers were detected in 5, 9, 6, 23, 11, and 8 of children aged 2, 4, 6, 12, 18, and 72 months, respectively. Conclusion: Since a considerable percentage of children had high levels of anti-pertussis IgG antibodies (≥2 SD), positive anti-pertussis IgA, and most importantly an increased level of anti-pertussis IgG geometric mean titer at 6 years of age, further investigations regarding the protection provided by the presently used pertussis vaccine seems necessary
Prevalence and determinants of under-nutrition among children under six: a cross-sectional survey in Fars province, Iran
Background:
Childhood malnutrition as a major public health problem among children in developing countries
can affect physical and intellectual growth and is also considered as a main cause of child morbidity and mortality.
The objective of this study was to estimate the prevalence of under-nutrition and identify determinants of
malnutrition among children under 6 years of age in Fars province, Iran.
Methods:
This survey was conducted by house to house visit through multi-stage sampling in 30 cities of Fars
province, during December 2012 to January 2013. A total of 15408 children, aged 0–6 years old, were studied
for nutritional assessment in terms of underweight, stunting, and wasting. Also, socio-demographic measures
were obtained from structured questionnaire. Backward stepwise logistic regression was used to relate underlying
factors to the odds of under-nutrition indices.
Results:
The rates of stunting, underweight, and wasting were 9.53, 9.66, and 8.19%, respectively. Male children
were more stunted compared to females (OR= 1.41, CI: 1.26–1.58). Also, stunting was significantly associated with
lower family income (OR= 3.21, CI: 1.17–8.85) and lower maternal education (OR= 0.80, CI: 0.64–0.98). Living
in urban areas, and poor water supply were identified as significant risk factors of all three types of childhood
under-nutrition. Moreover, Khamse and Arab ethnic groups were more vulnerable to under-nutrition. There was a
suggestion that non-access to health services were associated with wasting (OR= 1.87, CI: 1.39–2.52) and also large
family size was related to underweight (OR= 1.35, CI: 1.10–1.65).
Conclusion:
The prevalence of under-nutrition in the study population was categorized in low levels. However,
planning the public preventive strategies can help to control childhood under-nutrition according to underlying
factors of malnutrition in the study population including gender, settlement area, family size, ethnicity, family
income, maternal education, health services, and also safe water supply
High Titers of Hemagglutination Inhibition Antibodies against 2009 H1N1 Influenza Virus in Southern Iran
ABSTRACT Background: Pandemic flu had at least two waves in Iran. Knowing how many of the general population were already exposed to this infection has a major impact on national preventive measures. As of December 30, 2009, a total of 3672 confirmed cases of human infection with a novel Influenza A (2009 H1N1) virus had been reported in Iran with 140 deaths. Objective: In this study we aim to measure, as a pilot study, the seroprevalence of positive antibody titer (humoral immunity) against 2009 H1N1 virus in Iranian population in Shiraz, Southern Iran. Methods: Through cluster random sampling of families residing in Shiraz, 2553 subjects were selected and after a medical interview blood samples were taken and checked for polyclonal antibody against 2009 H1N1 antigen using hemagglutination inhibition assay. An antibody titer of more than 1:40 dilution was considered positive. Data were analyzed considering the demographic characteristics of the population and were compared among different age groups. Results: 1504 (58.91%) samples were tested positive for the presence of polyclonal antibody against 2009 H1N1 virus. The prevalence of positive titers were significantly higher in 60 to 64 years old group and significantly lower in 20 to 24 years old group (p<0.05). Data did not differ based on other demographic characteristics or the history of flu like illnesses in the past 6 months. Conclusion: High seroprevalence of antibody against 2009 H1N1 in the sera of our subjects describes either a high level of preexisting immunity against H1N1 in Iranian population or a high rate of asymptomatic infection in our area compared to other countries
An innovative method to assess clinical reasoning skills: Clinical reasoning tests in the second national medical science Olympiad in Iran
BACKGROUND: Clinical reasoning plays a major role in the ability of doctors to make a diagnosis and reach treatment decisions. This paper describes the use of four clinical reasoning tests in the second National Medical Science Olympiad in Iran: key features (KF), script concordance (SCT), clinical reasoning problems (CRP) and comprehensive integrative puzzles (CIP). The purpose of the study was to design a multi instrument for multiple roles approach in clinical reasoning field based on the theoretical framework, KF was used to measure data gathering, CRP was used to measure hypothesis formation, SCT and CIP were used to measure hypothesis evaluation and investigating the combined use of these tests in the Olympiad. A bank of clinical reasoning test items was developed for emergency medicine by a scientific expert committee representing all the medical schools in the country. These items were pretested by a reference group and the results were analyzed to select items that could be omitted. Then 135 top-ranked medical students from 45 medical universities in Iran participated in the clinical domain of the Olympiad. The reliability of each test was calculated by Cronbach's alpha. Item difficulty and the correlation between each item and the total score were measured. The correlation between the students' final grade and each of the clinical reasoning tests was calculated, as was the correlation between final grades and another measure of knowledge, i.e., the students' grade point average. RESULTS: The combined reliability for all four clinical reasoning tests was 0.91. Of the four clinical reasoning tests we compared, reliability was highest for CIP (0.91). The reliability was 0.83 for KF, 0.78 for SCT and 0.71 for CRP. Most of the tests had an acceptable item difficulty level between 0.2 and 0.8. The correlation between the score for each item and the total test score for each of the four tests was positive. The correlations between scores for each test and total score were highest for KF and CIP. The correlation between scores for each test and grade point average was low to intermediate for all four of the tests. CONCLUSION: The combination of these four clinical reasoning tests is a reliable evaluation tool that can be implemented to assess clinical reasoning skills in talented undergraduate medical students, however these data may not generalizable to whole medical students population. The CIP and KF tests showed the greatest potential to measure clinical reasoning skills. Grade point averages did not necessarily predict performance in the clinical domain of the national competitive examination for medical school students
Impact of neuraminidase inhibitors on influenza A(H1N1)pdm09‐related pneumonia: an individual participant data meta‐analysis
BACKGROUND: The impact of neuraminidase inhibitors (NAIs) on influenza‐related pneumonia (IRP) is not established. Our objective was to investigate the association between NAI treatment and IRP incidence and outcomes in patients hospitalised with A(H1N1)pdm09 virus infection.
METHODS: A worldwide meta‐analysis of individual participant data from 20 634 hospitalised patients with laboratory‐confirmed A(H1N1)pdm09 (n = 20 021) or clinically diagnosed (n = 613) ‘pandemic influenza’. The primary outcome was radiologically confirmed IRP. Odds ratios (OR) were estimated using generalised linear mixed modelling, adjusting for NAI treatment propensity, antibiotics and corticosteroids.
RESULTS: Of 20 634 included participants, 5978 (29·0%) had IRP; conversely, 3349 (16·2%) had confirmed the absence of radiographic pneumonia (the comparator). Early NAI treatment (within 2 days of symptom onset) versus no NAI was not significantly associated with IRP [adj. OR 0·83 (95% CI 0·64–1·06; P = 0·136)]. Among the 5978 patients with IRP, early NAI treatment versus none did not impact on mortality [adj. OR = 0·72 (0·44–1·17; P = 0·180)] or likelihood of requiring ventilatory support [adj. OR = 1·17 (0·71–1·92; P = 0·537)], but early treatment versus later significantly reduced mortality [adj. OR = 0·70 (0·55–0·88; P = 0·003)] and likelihood of requiring ventilatory support [adj. OR = 0·68 (0·54–0·85; P = 0·001)].
CONCLUSIONS: Early NAI treatment of patients hospitalised with A(H1N1)pdm09 virus infection versus no treatment did not reduce the likelihood of IRP. However, in patients who developed IRP, early NAI treatment versus later reduced the likelihood of mortality and needing ventilatory support
A Narrative Review of Influenza: A Seasonal and Pandemic Disease
Influenza is an acute respiratory disease caused by the influenza A or B virus. It often occurs in outbreaks and epidemics worldwide, mainly during the winter season. Significant numbers of influenza virus particles are present in the respiratory secretions of infected persons, so infection can be transmitted by sneezing and coughing via large particle droplets. The mean duration of influenza virus shedding in immunocompetent adult patients is around 5 days but may continue for up to 10 days or more—particularly in children, elderly adults, patients with chronic illnesses, and immunocompromised hosts. Influenza typically begins with the abrupt onset of high-grade fever, myalgia, headache, and malaise. These manifestations are accompanied by symptoms of respiratory tract illnesses such as nonproductive cough, sore throat, and nasal discharge. After a typical course, influenza can affect other organs such as the lungs, brain, and heart more than it can affect the respiratory tract and cause hospitalization. The best way to prevent influenza is to administer annual vaccinations. Among severely ill patients, an early commencement of antiviral treatment (<2 d from illness onset) is associated with reduced morbidity and mortality, with greater benefits allied to an earlier initiation of treatment. Given the significance of the disease burden, we reviewed the latest findings in the diagnosis and management of influenza
<i>Fasciola hepatica</i>: A cause of obstructive Jaundice in an elderly man from Iran
Fascioliasis is a zoonotic infection caused by Fasciola hepatica . Humans can become accidental hosts of this parasite by ingesting contaminated drinking water or plants in endemic area. The north of Iran is one of the regions. This disease is rarely seen with jaundice caused by obstruction of the biliary tree. We report a case of human fascioliasis with obstructive jaundice who was diagnosed using endoscopic retrograde cholangiopancreatography (ERCP). This report confirms the diagnostic role of ERCP in patients with obstructive jaundice caused by biliary fascioliasis
The Rate of Knowledge and Practice of Medical Residents of Shiraz Medical School in Regard to Evidence-based Medicine
Background & Objective: Evidence-based medicine (EBM) is defined as the application of the best research evidence in making decisions in the management of the individual patient. EBM, due to its importance, has obtained great consideration in recent years. This study was designed to determine the knowledge of Medical residents in Shiraz School of Medicine about EBM and the application of it by them.
Methods : In this cross-sectional study performed in 2006, 71 residents of Shiraz School of Medicine were studied by using a questionnaire. The validity of the questionnaire was approved by getting experts’ opinions and internal consistency reliability was determined in a pilot study.
Results : In whole, 93.9% of residents had positive attitudes toward EBM, but 80.3% of them reported that they had not passed any formal education in this field. From all participants, 85% have access to internet but more than 70% of them were not aware of EBM resources and 60.9% of them mentioned that for the management of their patients during the previous year they had used Medline or other search engines less than 10 times.
Conclusion : According to the obtained results, in spite of positive attitude toward EBM and internet access, residents have not yet integrated the use of EBM with their professional practice widely, and also they are not familiar with specific EBM Sites. This may be due to the lack of education in the field of EBM. Because of the important role of Medical residents in making clinical decisions and also their role in training Medical students, inclusion of EBM training courses in their educational program is highly necessary.
