Abstract
OBJECTIVE New coronavirus (COVID-19) pandemic socioeconomically affected the world. In this study, we measured the perceived stress in response to the COVID-19 pandemic among Iranians to determine the groups at both extremes of the spectrum followed by identifying the stressors and coping mechanisms. METHODS This study was a mixed-methods study. We distributed a web-based 10-item perceived stress scale (PSS-10), to measure perceived stress score (PSS), through social networks from March 12 to 23, 2020. Then, we interviewed 42 students, 31 homemakers, 27 healthcare providers, and 21 male participants to identify the sources of stress and coping mechanisms. RESULTS Finally, 13,454 participants completed the questionnaires. The median and interquartile range (IQR) of the participants' PSS was 21 (15-25). Students, homemakers, and healthcare workers (HCWs) showed a higher median (IQR) of PSS compared to other groups (23 [18 to 27], 22 [16 to 26], and 19 [14 to 24], respectively). Male participants showed a lower median (IQR) PSS (17 [12 to 23]). Content analysis of 121 participants' answers showed that the most common stressors were school-related issues mentioned by students, family-related issues mentioned by homemakers, and COVID-19-related issues mentioned by healthcare providers. Male participants' coping mechanisms were mostly related to the perception of their abilities to cope with the current crisis. CONCLUSION Our participants clinically showed a moderate level of PSS. The main stressors among students, homemakers, and HCWs were related to their principal role in this period, and male participants' coping mechanisms were inspired by the self-image retrieved from the social perspectives.

The Effects of an Empathic Communication Workshop on Internal Medicine Residents' Self-Perceived Empathy and Their Patients' Perception of Physician's Empathy: A Single-Group Experimental Study. Med J Islam Repub Iran 2022; 36:137. [PMID: 36479531 PMCID: PMC9719582 DOI: 10.47176/mjiri.36.137] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/01/2022] [Indexed: 12/24/2022] Open
Abstract
Background: Empathetic communication improves the physician-patient relationship and enhances patient and physician satisfaction. This study aims to evaluate the impact of empathic communication skills training on physicians' self-perceived performance and patient satisfaction regarding the empathetic quality of their relationship with their physicians. Methods: In this single-group before-after experimental study, we recruited 50 internal medicine residents at a large teaching hospital. We assessed the residents' empathy using the Jefferson Scale of Empathy before and 3 weeks after an 8-hour workshop on empathic communication skills. We also recruited 50 of their patients before and another 50 patients 3 weeks after the training to assess the patient's perceptions of their physician's empathy using the Consultation and Relational Empathy scale. Physicians' and patients' mean scores on empathetic care at the beginning of the study were then compared using paired t-tests with their scores after the workshop. Results: The residents' mean score on Jefferson Empathy Scale increased from 81.1(95%CI:78.8-83.3) at baseline to 96.8(95%CI:93.6-100) following the workshop (p < 0.001). Before the empathetic communication skills training, patients assessed their doctors' empathy at 68.3(95%CI:63.5-73.2). After the intervention, this improved to 84.9(95%CI:82.2-87.5) (p < 0.001). Conclusion: In this study, both the residents and their patients stated that the residents' empathy skills had significantly improved after an empathetic communication workshop for internal medicine residents.

COVID-19 related stigma among the general population in Iran. BMC Public Health 2022; 22:1681. [PMID: 36064385 PMCID: PMC9442561 DOI: 10.1186/s12889-022-14039-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/11/2022] [Accepted: 08/22/2022] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND COVID-19 related stigma has been identified as a critical issue since the beginning of the pandemic. We developed a valid and reliable questionnaire to measure COVID-19 related enacted stigma, inflicted by the non-infected general population. We applied the questionnaire to measure COVID-19 related enacted stigma among Tehran citizens from 27 to 30 September 2020. METHODS A preliminary questionnaire with 18 items was developed. The total score ranged from 18 to 54; a higher score indicated a higher level of COVID-19 related stigma. An expert panel assessed the face and content validity. Of 1637 randomly recruited Tehran citizens without a history of COVID-19 infection, 1064 participants consented and were interviewed by trained interviewers by phone. RESULTS Item content validity index (I-CVI), Item content validity ratio (I-CVR), and Item face validity index (I-FVI) were higher than 0.78 for all 18 items. The content and face validity were established with a scale content validity index (S-CVI) of 0.90 and a scale face validity index (S-CVI) of 93.9%, respectively. Internal consistency of the questionnaire with 18 items was confirmed with Cronbach's alpha of 0.625. Exploratory factor analysis revealed five latent variables, including "blaming", "social discrimination", "dishonor label", "interpersonal contact", and "retribution and requital attitude". The median of the stigma score was 24 [25th percentile: 22, 75the percentile: 28]. A large majority (86.8%) of participants reported a low level of stigma with a score below 31. None of the participants showed a high level of stigma with a score above 43. We found that the higher the educational level the lower the participant's stigma score. CONCLUSION We found a low level of stigmatizing thoughts and behavior among the non-infected general population in Tehran, which may be due to the social desirability effect, to the widespread nature of COVID-19, or to the adaptation to sociocultural diversity of the large city.

Elevated Serum Levels of Interleukin-15 in Pemphigus Vulgaris Patients: A Potential Therapeutic Target. Dermatol Pract Concept 2022; 12:e2022118. [PMID: 36159109 PMCID: PMC9464526 DOI: 10.5826/dpc.1203a118] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 11/13/2021] [Indexed: 12/04/2022] Open
Abstract
Introduction Pemphigus vulgaris (PV) is a rare autoimmune disease that causes painful blistering. Interleukin-15 (IL-15) as a member of the immunoregulatory cytokines family is associated with the development of the chronic inflammatory or autoimmune disease. There is not much information available in the literature on the exact role IL-15 plays in PV. Objectives The goal of this study was to evaluate the serum levels of IL-15 in patients with PV and assess the association of IL-15 with anti-desmoglein antibodies and the severity of the disease. Methods Fifty-three individuals affected with active PV and 38 age- and gender-matched healthy controls were participated in this study. Disease severity was assessed using Autoimmune Bullous Skin Disorder Intensity Score (ABSIS). Serum levels of IL-15 (pg/mL) and anti-desmoglein antibodies (Dsg1, 3) were determined. Results In the patient group, IL-15 serum levels were statistically higher than those in the control group (3.71 ± 1.5 vs. 0.79 ± 1.03, P < 0.001). A positive correlation was found between serum levels of IL-15 and ABSIS (r = 0.5, P = 0.04). We found no significant correlation between serum concentrations of IL-15 and antidesmoglein antibodies (Dsg1 or Dsg3). Conclusions An increase in serum level of IL-15 in patients with PV and its relationship with disease severity suggest that this cytokine possibly contributes to the pathogenesis of the disease and targeting IL-15 will likely provide a new insight into the treatment of this disease.

Abstract
Introduction
COVID-19-related stigma has been raised as a crisis since the beginning of the pandemic. We intended to develop a valid and reliable questionnaire to measure COVID-19-related stigma, attributed by the non-infected general population, and applied it in Tehran from September to October 2020.
Objectives
This study measures the COVID-19-related stigma attributed by the non-infected general population using a valid and reliable questionnaire specific to COVID-19-related stigma.
Methods
A preliminary questionnaire with 18 items was developed. The score ranged from 18 to 54 while the higher score indicating a higher level of COVID-19-related stigma. Out of 1064 randomly recruited Tehran citizens without a history of COVID-19 infection, 630 participants, who completely responded to the questions on a phone call, entered the study.
Results
The content validity was established with a scale content validity index of 0.90. Item CVI and Item content validity ratio were higher than 0.78 for all items. Internal consistency was confirmed with Cronbach’s alpha of 0.625. Exploratory factor analysis revealed seven latent variables, including “blaming and penalty-seeking behavior”, “social discrimination”, “dishonor label”, “interpersonal contact”, “spreading rumors and myths”, “overvalued idea”, and “apathy toward the patients”. The mean (SD) of the score was 25.1(4.71) in our study. 86.8% of participants reported a low level of stigma with a score below 31. 13.2% of them demonstrated a moderate level of stigma, and none of the participants showed a high level of stigma.
Conclusions
we found a low level of stigmatizing thoughts and behavior in Tehran, which may be due to social desirability bias.

Abstract
Introduction This study was a mixed-methods study. We distributed a web-based 1scale (PSS-10), to measure perceived stress scores, through social networks from March 12 to 23, 2020. Then, we interviewed 42 students, 31 homemakers, 27 healthcare providers, and 21 male participants to identify the sources of stress and coping mechanisms. Objectives We examined the correlates of stress among a large sample of Iranian citizens, the second country hit hard by the pandemic, and still a hot spot. Methods This anonymous survey had 19 items falling into two sections: sociodemographic data and Cohen’s 10-item perceived stress scale (PSS-10). Results A statistically significant difference was observed between the levels of perceived stress in individuals with different health statuses with a higher median of total PSS-10 scores reported for hospitalized individuals. The total PSS-10 scores were higher in those who were practicing self-isolation, had a relative affected with COVID-19 disease, and had experienced the death of a relative due to COVID-19 disease. Conclusions This study highlighted the most vulnerable groups overloaded with stress in society and the sources of their stress. Furthermore, we identified the groups that perceived lower levels of stress along with their coping mechanisms. The most frequent source of stress among the most stressful groups including homemakers, students, and health care workers has directly related to their job and their principal role in this period. Abstract thought about the COVID-19 pandemic and its complications were more prevalent among students while homemakers and health care providers showed concrete thinking about the COVID-19 pandemic.

Arrhythmogenic right ventricular cardiomyopathy in patients with biallelic JUP-associated skin fragility. Sci Rep 2020; 10:21622. [PMID: 33303784 PMCID: PMC7729882 DOI: 10.1038/s41598-020-78344-9] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/29/2020] [Accepted: 11/09/2020] [Indexed: 12/04/2022] Open
Abstract
Arrhythmogenic right ventricular cardiomyopathy (ARVC), with skin manifestations, has been associated with mutations in JUP encoding plakoglobin. Genotype–phenotype correlations regarding the penetrance of cardiac involvement, and age of onset have not been well established. We examined a cohort of 362 families with skin fragility to screen for genetic mutations with next-generation sequencing-based methods. In two unrelated families, a previously unreported biallelic mutation, JUP: c.201delC; p.Ser68Alafs*92, was disclosed. The consequences of this mutation were determined by expression profiling both at tissue and ultrastructural levels, and the patients were evaluated by cardiac and cutaneous work-up. Whole-transcriptome sequencing by RNA-Seq revealed JUP as the most down-regulated gene among 21 skin fragility-associated genes. Immunofluorescence showed the lack of plakoglobin in the epidermis. Two probands, 2.5 and 22-year-old, with the same homozygous mutation, allowed us to study the cross-sectional progression of cardiac involvements in relation to age. The older patient had anterior T wave inversions, prolonged terminal activation duration (TAD), and RV enlargement by echocardiogram, and together with JUP mutation met definite ARVC diagnosis. The younger patient had no evidence of cardiac disease, but met possible ARVC diagnosis with one major criterion (the JUP mutation). In conclusion, we identified the same biallelic homozygous JUP mutation in two unrelated families with skin fragility, but cardiac findings highlighted age-dependent penetrance of ARVC. Thus, young, phenotypically normal patients with biallelic JUP mutations should be monitored for development of ARVC.

Abstract
Background Defining the quality of life in the patients with epidermolysis bullosa (EB) is important in patient care and management. Evaluation of quality of life requires a valid and reliable scale. The Quality of Life in Epidermolysis Bullosa (EB-QoL) questionnaire, which is an English 17-item questionnaire, has emerged as a useful tool for assessing the quality of life in the patients with EB. Objective This study aimed to evaluate the psychometric properties of the Farsi version of the EB-QoL questionnaire among a group of Iranian patients with EB. Methods The Farsi version of the EB-QoL questionnaire was finalized after translation and back-translation. From the 100 patients with EB invited to participate in the study, 83 completed the questionnaire (response rate: 83%). Subsequently, the content validity and construct validity of the questionnaire were assessed. The reliability of the questionnaire was assessed with Cronbach's alpha. Moreover, the correlation between EB-QoL scores and EB severity scores (based on the Birmingham Epidermolysis bullosa severity score scale) was evaluated. Results A total of 83 patients (40 male and 43 female) with a median age of 15 years (interquartile range, 9–24 years) and an age range between 3 and 43 years were enrolled in this study. Mean ± standard deviation scores from the EB-QoL questionnaire were 43.7 ± 9.9. The translated EB-QoL questionnaire showed a high internal consistency (Cronbach alpha = 0.90) and adequate item-total correlation. Also, there was a significant correlation between EB-QoL and EB severity scores (r = 0.39; p < .001). Conclusion The Farsi version of EB-QoL questionnaire has acceptable validity and reliability. Thus, the questionnaire can be used for future studies to assess the quality of life among Iranian patients with EB.

Abstract
The proper development and function of skin and hair are dependent on proteolytic activities. Specifically, the matriptase-prostasin cascade is a series of proteolytic reactions in the epidermis integral to normal regulation of desquamation. An increasing amount of research describing this pathway has recently become available, and the importance of this pathway is exhibited by the association of genetic defects in this pathway with human diseases of the skin and hair. Given the relevance of this pathway to dermatology, we provide a review of the current understanding of its relevance to distinct clinical entities, including ichthyosis-hypotrichosis and Netherton syndromes.

Abstract
Background: Stress perceived by mothers during pregnancy is dependent on several factors and can lead to adverse pregnancy outcomes threatening mother and child physical and mental health.Objective: The purpose of the present study is measuring perceived stress of pregnant women by 14 items Cohen's perceived stress scale (PSS), detecting stressors surrounding pregnant women including male partner's role, intimate violence, socioeconomic situation, etc., as well as investigate the effect of perceived stress on pregnancy adverse outcomes.Method: Two hundred first gravid pregnant women between 18 and 35 years old at post labor ward entered our cross-sectional study. They were asked to fill out the PSS questionnaire and an information gatherer filled out the checklist for exposures and baseline characteristics.Result: Mean ± SD of participants' PSS was 25.5 ± 8.6. Mothers' PSS was significantly higher in group reported father's verbal aggression against mother (N = 71, 38%) (23.7 ± 9 versus 28.2 ± 7.2; p < .001) and father's physical aggression against mother (N = 28, 15%) compared to nonexposed one (24.9 ± 7.7 versus 28.4 ± 8.7; p: .04). Mothers' PSS score was significantly correlated with mothers' satisfaction from both fathers' emotional (r: -0.30, p: .001) and financial support (r: -0.34, p < .001) during pregnancy. Moreover, the mother's satisfaction from father's concomitance in prenatal care (PNC) visits was significantly correlated with the mother's perceived stress (r: 0.24, p: .001).Conclusion: Male partner's role during pregnancy directly affects the pregnant woman's perceived stress.

Abstract
Background: Pregnancy outcomes are affected by many different factors. One of the influential factors on pregnancy outcomes is the male partner as an important person to mother's wellbeing.Objective: The aim of the present study was to investigate the effects of male partner's role including socioeconomic support, emotional support, accompanying pregnant women during prenatal care visits (PNC) and labor, and the level of pregnant women's satisfaction from their partners' support and involvement during pregnancy on pregnancy outcomes.Method: Two hundred first gravid pregnant women with mean age of 23.2 ± 4.3 were studied. Primary outcomes were total maternal and neonatal adverse outcome (TMNAO), total maternal adverse end result (TMAE), and total neonatal adverse outcome (TNAO), regardless of the type of outcomes. Preterm labor and delivery; premature rupture of membrane (PROM) and preterm premature rupture of membrane (PPROM); preeclampsia and eclampsia; placental abruption; chorioamnionitis; stillbirth; meconium passage; maternal death; postpartum hemorrhage; poor progression labor; abnormal vaginal bleeding in third trimester of pregnancy; low birth weight and neonatal need for CPR or intubation, neonatal anomaly, NICU admission, and neonatal mortality were also analyzed as subgroup outcomes.Results: One hundred twenty-seven (63.5%) participants showed a kind of total maternal and neonatal adverse outcome (TMNAO), 72 (36%) deliveries resulted in a kind of neonatal adverse outcome (TNAO), and 104 (52%) of participants had a kind of maternal adverse end result (TMAE). Iranian fathers showed a significantly higher rate of TMNAO than Afghan fathers did (82 versus 69%, odds ratio: 2.9, 95% CI 1.0-7.8, p: .01). Mother's nationality showed the same result (82 versus 64%, odds ratio: 2.6, 95% CI 0.9-6.8, p: .03). Iranian fathers showed a significantly higher rate of TMAE than Afghan fathers did (79 versus 58%, odds ratio: 2.7, 95% CI 1.1-6.3, p: .01). Mother's nationality showed the same result (78 versus 60%, odds ratio: 2.4, 95% CI 1.0-5.6, p: 0.02). Neonates with Iranian fathers showed significantly more TNAO than those with Afghan fathers (50 versus 31%, odds ratio: 2.21, 95% CI 0.9-5.5, p: .04). The same trend was observed among Iranian mothers in comparison to Afghan mothers (50 versus 32%, odds ratio: 2.11, 95% CI 0.9-4.6, p: .06). Of mother's age, mother's BMI, father's age, father's BMI, and mother's nationality, only father's BMI contributed significantly to the binary logistic regression model (n = 116, R2: 9%, p: .028). It was found that for each decreased unit in BMI, the risk of TNAO was increased by 16%, p: .03. Moreover, Father's family history of preeclampsia resulted in a higher prevalence of total neonatal adverse outcome (TNAO) in comparison with lack of such family history (87 versus 43%, odds ratio: 8.9, 95% CI 1.1-74.5, p: .02). Besides, mothers' participation in prenatal care (PNC) visits, assessed by caregivers, was significantly more satisfactory in neonates without any adverse outcome than those with neonatal adverse outcomes (median (IQR) = 2 (1-2) versus 2 (2-3), p: .04). PROM, pre-eclampsia, NICU admission, neonatal intubation, low Apgar score minute 0, and low Apgar score minute 5 were significantly more prevalent in participants revealing positive father's family history of pre-eclampsia. Regarding psychosocial exposures, placental abruption was more prevalent in mothers with exposure to verbal aggression versus non-exposed ones (9 versus 2%, odds ratio: 4.0, 95% CI 0.9-24.6, p: .04). Moreover, a weak positive association between neonatal gestational age at birth and quality of mother's participation in PNC visits (r: +0.3, p: .01) as well as mother's satisfaction from father's commitment to PNC visits was found (r: +0.1, p: .03).Conclusion: Male partners may play a key role in pregnant women and fetus's heath.

Abstract
OBJECTIVE To evaluate the effects of copper (Cu) supplementation during pregnancy on the rupture of membranes and pregnancy outcomes. METHODS Study was conducted as a triple-blind randomized clinical trial. In one group, Cu in a dose of 1000 mg per day, and in the other group, placebo was prescribed orally from 16th week of pregnancy. RESULTS The women of the two groups did not have significant difference according to age, gestational age at recruitment, BMI, and socioeconomic conditions. There was no statistically significant difference between case and control group regarding the incidence of PPROM, PROM, preterm labor, vaginal bleeding during pregnancy, preeclampsia, and the incidence of placenta abruption. There was a 75% and 90% decrease in depressive symptoms in 2nd trimester and 3rd trimester in supplemented group, respectively. Also, there was a 45% and 80% decrease in anxiety symptoms in 2nd trimester and 3rd trimester in the supplemented group, respectively The rate of infection during pregnancy was significantly higher in control group (p = 0.046). There was no difference between the two groups according to neonatal outcomes. CONCLUSIONS Cu supplementation during pregnancy could not influence positively on ROM; however, it could improve some mood status of the women.

Antipsychotic drugs attenuate aberrant DNA methylation of DTNBP1 (dysbindin) promoter in saliva and post-mortem brain of patients with schizophrenia and Psychotic bipolar disorder. Am J Med Genet B Neuropsychiatr Genet 2015; 168:687-96.

Abstract
Due to the lack of genetic association between individual genes and schizophrenia (SCZ) pathogenesis, the current consensus is to consider both genetic and epigenetic alterations. Here, we report the examination of DNA methylation status of DTNBP1 promoter region, one of the most credible candidate genes affected in SCZ, assayed in saliva and post-mortem brain samples. The Illumina DNA methylation profiling and bisulfite sequencing of representative samples were used to identify methylation status of the DTNBP1 promoter region. Quantitative methylation specific PCR (qMSP) was employed to assess methylation of DTNBP1 promoter CpGs flanking a SP1 binding site in the saliva of SCZ patients, their first-degree relatives and control subjects (30, 15, and 30/group, respectively) as well as in post-mortem brains of patients with SCZ and bipolar disorder (BD) versus controls (35/group). qRT-PCR was used to assess DTNBP1 expression. We found DNA hypermethylation of DTNBP1 promoter in the saliva of SCZ patients (∼12.5%, P = 0.036), particularly in drug-naïve patients (∼20%, P = 0.011), and a trend toward hypermethylation in their first-degree relatives (P = 0.085) versus controls. Analysis of post-mortem brain samples revealed an inverse correlation between DTNBP1 methylation and expression, and normalization of this epigenetic change by classic antipsychotic drugs. Additionally, BD patients with psychotic depression exhibited higher degree of methylation versus other BD patients (∼80%, P = 0.025). DTNBP1 promoter DNA methylation may become a key element in a panel of biomarkers for diagnosis, prevention, or therapy in SCZ and at risk individuals pending confirmatory studies with larger sample sizes to attain a higher degree of significance.

IRANIAN RED CRESCENT MEDICAL JOURNAL 2013; 15:649-54. [PMID: 24578830 PMCID: PMC3918187 DOI: 10.5812/ircmj.8267] [Citation(s) in RCA: 23] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/22/2012] [Revised: 05/20/2013] [Accepted: 07/14/2013] [Indexed: 11/17/2022]
Abstract
Background Since pulmonary hypertension (PH) in patients with chronic obstructive pulmonary diseases (COPD) causes poor prognosis and inflammatory process involved in PH, it is supposed that Statins with anti-inflammatory effects might be useful in the treatment of PH. Objectives The aim of this study was to evaluate the influence of Atorvastatin on the treatment of pulmonary hypertension in patients with COPD. Patients and Methods A registered (IRCT201108257411N1), triple-blind, randomized controlled trial was performed in Rasoule Akram hospital, Tehran, from 2009 to 2011. Forty five patients with secondary pulmonary hypertension due to COPD were recruited and randomized to two groups receiving either Atorvastatin 40 mg/d or placebo in addition to their current treatment for 6 months. The outcomes including systolic pulmonary arterial hypertension (SPAH), cardiac output (CO), right ventricular size (RVS), CRP, 6 min walk distance test (6MWD), and spirometry parameters were measured after 6 months. Results Baseline characteristics were similar in both groups. After 6 months, pulmonary hypertension changed from 48.5 ± 6.9 to 42.9 ± 9.3 mmHg for Atorvastatin users and from 49.7 ± 11.4 to 48.2 ± 14.6 mmHg for Placebo users (P = 0.19, CI - 13.57 - 2.89), 6MWD after 6 months was 339 ± 155 meters in case group versus 340 ± 106 meters in control group (P = 0.98, CI - 92.58 - 91.15). There were no significant changes in other outcomes including CRP, RVS, CO and spirometry parameters. Conclusions Although we found a trend towards decreasing SPAH and improving 6MWD, no statistically significant shift were detected in our outcomes due to inadequate sample size.

To compare PubMed Clinical Queries and UpToDate in teaching information mastery to clinical residents: a crossover randomized controlled trial. PLoS One 2011; 6:e23487. [PMID: 21858142 PMCID: PMC3155565 DOI: 10.1371/journal.pone.0023487] [Citation(s) in RCA: 30] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/29/2011] [Accepted: 07/18/2011] [Indexed: 11/24/2022] Open
Abstract
Purpose To compare PubMed Clinical Queries and UpToDate regarding the amount and speed of information retrieval and users' satisfaction. Method A cross-over randomized trial was conducted in February 2009 in Tehran University of Medical Sciences that included 44 year-one or two residents who participated in an information mastery workshop. A one-hour lecture on the principles of information mastery was organized followed by self learning slide shows before using each database. Subsequently, participants were randomly assigned to answer 2 clinical scenarios using either UpToDate or PubMed Clinical Queries then crossed to use the other database to answer 2 different clinical scenarios. The proportion of relevantly answered clinical scenarios, time to answer retrieval, and users' satisfaction were measured in each database. Results Based on intention-to-treat analysis, participants retrieved the answer of 67 (76%) questions using UpToDate and 38 (43%) questions using PubMed Clinical Queries (P<0.001). The median time to answer retrieval was 17 min (95% CI: 16 to 18) using UpToDate compared to 29 min (95% CI: 26 to 32) using PubMed Clinical Queries (P<0.001). The satisfaction with the accuracy of retrieved answers, interaction with UpToDate and also overall satisfaction were higher among UpToDate users compared to PubMed Clinical Queries users (P<0.001). Conclusions For first time users, using UpToDate compared to Pubmed Clinical Querries can lead to not only a higher proportion of relevant answer retrieval within a shorter time, but also a higher users' satisfaction. So, addition of tutoring pre-appraised sources such as UpToDate to the information mastery curricula seems to be highly efficient.

Abstract
BACKGROUND The efficacy of bedside information products has not been properly evaluated, particularly in developing countries. AIM To compare four evidence-based textbooks by comparing efficacy of their use by clinical residents, as measured by the proportion of questions for which relevant answers could be obtained within 20 min, the time to reach the answer and user satisfaction. METHODS One hundred and twelve residents were taught information mastery basics and were randomly allocated to four groups to use: (1) ACP PIER, (2) Essential Evidence Plus (formerly InfoRetriever), (3) First Consult, and (4) UpToDate. Participants received 3 of 24 questions randomly to retrieve the answers from the assigned textbook. Retrieved answers and time-to-answers were recorded by special designed software, and the researchers determined if each recorded answer was relevant. RESULTS The rate of answer retrieval was 86% in UpToDate, 69% in First Consult, 49% in ACP PIER, and 45% in Essential Evidence Plus (p < 0.001). The mean time-to-answer was 14.6 min using UpToDate, 15.9 min using First Consult, 16.3 min using Essential Evidence Plus, and 17.3 min using ACP PIER (p < 0.001). CONCLUSION UpToDate seems more comprehensive in content and also faster than the other three evidence-based textbooks. Thus, it may be considered as one of the best sources for answering clinicians' questions at the point of care.
