Online Health Information Seeking Behavior among Iranian Pregnant Women: A Case Study

Objective: The present study aimed to investigate the health information seeking behavior, applicability and the evaluation of health information obtained from the Internet by Iranian pregnant women. Design and setting: The present study was descriptive-survey. The study population included 196 pregnant women in different gestational months referred to hospitals with Obstetrics and Gynecology ward in Hamadan, Iran on September and October in 2016 who were selected based on stratified random sampling method. The data were collected through a researcher-made questionnaire. Findings: Most pregnant women, while facing with pregnancy problems, seek out health information from the Internet and they often trust the information and share with their doctor. The information increases their awareness about pregnancy. Websites and social networks are two important sources in finding health information and reference of content and educated authors are regarded as two important criteria in evaluating health information obtained from the Internet. In addition, fetal development and nutrition during pregnancy were regarded as two important issues having the most searches among pregnant women. Conclusion: Internet has become a popular source for health information finding. The high importance of the accuracy of information used by pregnant women and the vulnerability of this range of society highlight the need to equip hospital libraries with update resources of the information and amenities such as suitable seats, ventilation, and the like. Using medical librarians and informants and referral of pregnant women to these libraries by a doctor or midwife in order to obtain valid information, standardization of Persian-based digital libraries related to health, introducing valid portals for pregnant women are regarded as some important issues in this regard. Familiarizing pregnant women, especially in developing countries, with various types of content on the Internet and how to find valid information by medical librarians can facilitate the access to information for pregnant women and reduce many complications raised by the lack of reliable and valid information

Pattern mining analysis of pulmonary TB cases in Hamadan province: Using space-time cube

Background and aims: One of the most common approach to understanding spatial and temporal trends of event data is to break it up into a series of time snapshots. Therefore space-time cube method applied in order to portray the likely trend in occurrence of the pulmonary tuberculosis (TB) cases. Methods: In this study, information of all patients with pulmonary TB recorded in surveillance system of Hamadan University of Medical Sciences from 2005 to 2013 years were studied. After geocoding the residence location address of pulmonary TB cases and converted to point layer, the space-time cube was used to detect likely trends in occurrence of tuberculosis. Then, based on the space-time cube results the Emerging Hot Spot Analysis was run to clustering hot and cold spots. Results: There was significant increasing trend in occurrence of pulmonary TB cases. The statistic trend was 2.1871 and P-value was 0.0287, as well as 36 hot spots locations was detected that have been form approximately in central areas of province. Conclusion: Significantly increasing trend in occurrence of TB cases and existence of hot spot, especially intensifying hot spots in central areas of province can represent pay more attention to this disease in mentioned areas in order to detect the change in epidemiological face and to implement suitable prevention programs

Establishment of Brucellosis Relapse and Complications Registry: A Study Protocol

Brucellosis is an endemic bacterial zoonotic disease in developing countries; that is a serious public health problem in Iran. Brucellosis is a life-threatening multi-system disease in human with different clinical manifestations, complications and relapse. The incidence of brucellosis in Hamadan province, west of Iran is high. In addition, there is few reliable and population-based studies regarding relapse and complications of brucellosis in developing countries, therefore establishment of the registry system in areas with adequate occurrence of cases is needed to better understand the predictors of brucellosis relapse and complications and management of the disease. Detecting occurrence of relapse and complications over time and by geographical area provide information for further investigations and identification of health system deficiencies in the management of patients

Development of information diffusion models based on mathematical models of disease diffusion

Abstract Purpose: Analysis of information diffusion process based on models of spread of epidemics is one of the issues considered by the researchers. Limited studies have addressed investigation and analysis of scientific information diffusion. Current study was conducted aiming at identifying scientific information diffusion process among academic faculty members using mathematical models of spread of diseases during 2016. Methodology: Mathematical models of spread of epidemics including SIS, SI, and SIR models were used for analysis of scientific information diffusion. The study was conducted using semi-experimental method on 147 faculty members in three stages including evaluation of current status at time t0, after implementation of intervention of models including susceptible, infected (informed) and recovered (information saturation). Using statistical methods, chance of disease transmission from each compartment to the next one was measured. Findings: Research findings suggested feasibility of SIS, SI, and SIR models in describing information diffusion process. People who are susceptible to scientific information will not remain in a constant state after receiving information. So that 51.6% of the people remain in a state of informed and 39.1% return to susceptible conditions. Also, only 9.3% of people will switch to saturated and unnecessary conditions. Conclusion: Application of models of epidemics spread and its extension to scientific information diffusion is accurate. In addition, mostly individuals will remain at constant state after receiving scientific information

The Effect of a Web-based Educational Program on Perevention of Hookah Smoking among Adolescent Girls: Application of Theory of Planned Behavior

Background: The prevalence of hookah is increasing worldwide and in all age groups, especially among women. Therefore, this study was conducted to determine the effect of web-based educational program in the prevention of hookah smoking among girls in Kermanshah, Iran, using theory of planned behavior (TPB).Methods: This study was a randomized controlled trial performed on 110 adolescent girls in Kermanshah City in 2020. Multistage random sampling was used in this study. The data collection tool included a researcher made questionnaire. Designed intervention was implemented for the intervention group in 5 educational sessions according to analysis of pre-test results. Data were collected 3 months after the end of the training intervention. Data analysis was carried out using SPSS software.Findings: The presented interventions significantly improved the structures of attitude (P < 0.001), subjective norms (P < 0.001), and intention (P < 0.001) in the intervention group compared with the control group. However, the difference between perceived behavioral control score in the two groups was not significant (P = 0.131). There was also a significant difference in reducing the behavior of hookah smoking between the intervention and control groups after the educational intervention.Conclusion: Using web-based interventions is a good educational strategy for prevention of hookah smoking in adolescent girls

Serological and molecular investigation of human brucellosis in participants of Famenin brucellosis cohort study, Hamadan, Iran

Background and Objectives: Brucella is an intracellular pathogen that causes brucellosis in humans and animals. This study aimed to assess the results of brucellosis seroprevalence among participants of the Famenin brucellosis cohort with molecular investigation technique and determine Brucella-approved species. Materials and Methods: Following the first phase of the Famenin brucellosis cohort in 2016 which investigated the seroprevalence of brucellosis among 2367 participants in Famenin city, a total of 575 people including all seropositive and some seronegative people were examined again by wright serological tests in 2019. The PCR assay was accomplished on all cases that have wright titers ≥ 1/20 for tracing Brucella DNA using BCSP31 target gene and IS711 locus. Results: Out of 575 studied cases, 145 people had wright titers ≥ 1/20. The PCR reactions of these 145 blood samples were positive in 63/145 (43.44%) tested samples using primers (B4/B5) for Brucella genus detection. In the second PCR assay using specific-primers for Brucella abortus and Brucella melitensis, 18/63 (28.57%) of the samples were diagnosed as B. abortus, and 18/63 (28.57%) were diagnosed as B. melitensis. Conclusion: In this study, using the selected specific genes for the diagnosis of Brucella in the genus and species levels, the PCR technique was evaluated as a promising method for the rapid and safe detection of brucellosis besides the serological test for more accurate detection of brucellosis especially in cases that are not definitive

Non-Pharmacologic Interventions in COVID-19 Pandemic Management; a Systematic Review

Introduction: Different countries throughout the world have adopted non-pharmacologic interventions to reduce and control SARS - CoV-2. In this systematic approach, the impact of non-pharmacologic interventions in management of COVID-19 pandemic was assessed. Methods: Following Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines, systematic search was carried out on the basis of a search strategy on PubMed, Web of Science, Scopus, and WHO databases on COVID-19. The impact of travel ban, personal protective equipment, distancing, contact tracing, school closure, and social distancing and the combined effect of interventions on COVID-19 were assessed. Results: Of the 14,857 articles found, 44 were relevant. Studies in different countries have shown that various non-pharmacological interventions have been used during the COVID-19 pandemic. The travel ban, either locally or internationally in most of the countries, movement restriction, social distancing, lockdown, Personal Protective Equipment (PPE), quarantine, school closure, work place closure, and contact tracing had a significant impact on the reduction of mortality or morbidity of COVID-19. Conclusion: Evidence shows that the implementation of non-pharmacologic interventions (NPIs), for example, social distancing, quarantine, and personal protective equipment’s are generally effective and the best way to prevent or reduce transmission. However, this study suggests that the effectiveness of any NPI alone is probably limited, thus, a combination of various actions, for example, social distancing, isolation, and quarantine, distancing in the workplace and use of personal protective equipment, is more effective in reducing COVID-19
