Volume 6, Issue 3 (7 2012)
Abstract

Background and Aim: Nowadays, because of the intense competition between nutrition consultants and rapid changes in patients' demands for nutrition counseling, application of the concepts such as "Entrepreneurial Opportunities Recognition" in this field seems unavoidable. One of the most commonly used methods for recognition of entrepreneurial opportunities is "Strategic Analysis of External Environment". Present survey has been conducted in order to study the impact of nutrition consultants' educational level on their strategic analysis about entrepreneurial opportunities.

Materials and Methods: This analytical survey was implemented based on the data (nutrition consultants' educational levels and their responses regarding the supply and demand for nutrition counseling services) which was collected during a previous study entitled ((Analysis of supply and demand trends in the field of diabetes nutrition counseling: A basic step towards identifying the entrepreneurial opportunities for nutrition consultants)). Also, ((Spearman's correlation test)) and ((GLM multivariate test)) were performed for the analysis of aforementioned data.

Results: Both statistical tests showed that nutrition consultants' educational levels (including 1- Bachelor of Science and 2- Master of Science and PhD) had significant relationship with two-thirds of their comments.

Conclusion: Nutrition consultants' educational level has a relative impact on their strategic analysis about the entrepreneurial opportunities.

Volume 10, Issue 5 (1-2017)
Abstract

Background and Aim: Giardiasis is the most common pathogenic gastrointestinal parasite worldwide and transmitted by ingesting parasite cyst, through water and food and person-to-person contact. Therefore in food handlers and child care workers it is of high importance. In this study we surveyed the job of individuals with giardiasis.
Materials and Methods: This study was a pilot descriptive-analytic study. Hundred and nine stool samples were collected from individuals referred to medical centers affiliated to Tehran University of Medical Sciences for health certificate. 
Samples were examined with wet mount smear and formol-ether concentration methods. Also a questionnaire was given to each individual.
Results: Sixty nine samples were infected with Giardia lamblia. among positive samples for Giardia lamblia 25 (36.23%) were related to food handlers and occupations which are most  frequently associated with food, one (1.44%) nurse, one (1.44%) managing director of the nursery, two (2.89%) housekeepers  and one servant (1.44%).
Conclusion: Person-to-person Giardia lamblia transmission is often associated with poor hygiene and sanitation, most commonly by food handlers.
Also, day- care workers have a higher risk of infecting children attending day-care centers. Therefore particular attention should be paid to health of this workers as well as three times stool examination.

Abstract
Background and Aim: Due to the importance and position of the health sector in society and consideration of industry 4.0 during these days, we witness an increase in the spread of state-of-the-art (smart) technologies in various fields, on one hand, and an evolutionary development by integrating healthcare and technology, on the other hand. Thus, the application of smart technologies can help to overcome many of the healthcare sector limitations. This study aimed to propose an appropriate model for deploying smart services in the Iranian healthcare system.
Material and Methods: This was a qualitative research study based on thematic analysis in 2020. The required data were extracted by literature review and expert interviews. A sample of 15 experts were selected using purposive sampling. Sampling was continued until full data saturation was reached. The data were collected using semi-structured interviews. The interviews were implemented and analyzed in MAXQDA. Finally, a qualitative method was developed.
Results: Based on the findings of this research, 202 open codes were extracted and 23 basic themes (sub- themes) were identified to design the model of deployment smart services in the Iranian health sector which categorized in seven organizing themes (main themes) consist deployment planning, execution management, task organization frame work, national preparedness, stage-setting, organizational interventions, and resistance management. Then, according to the above themes, the thematic model was provided which has a suitable model fitness (IFI: 0.934, NFI: 0.959, RMSEA: 0.080).
Conclusion: Providing the model for deploying smart health care and use of these technologies help to significantly improve the quality of health services, improve access to these services, reduce costs and thus improve health of society.

Abstract
Background and Aim: All people living in a society are not equally at risk of COVID-19 infection and hospitalization. The current study is aimed to determine the factors related to COVID-19 infection and hospitalization among participants of Ravansar Non-Communicable Disease (RaNCD) cohort study. 
Materials and Methods: The present study was conducted between 28th February, 2020 to 27th November, 2021. Data from the RaNCD study, morbidity and hospitalizations cases (extracted from the medical care monitoring system, SAMA system and the handwritten list of the health department) and positive serological results were used. For the case-cohort study, 626 confirmed and/or probable cases and 2107 randomly selected participants as sub-cohort were recruited. For the case-control study, 188 COVID-19 hospitalized patients from RaNCD (as cases) and 632 positive outpatients identified as controls. Data were analyzed using Cox and logistic regression, respectively. 
Results: In case-cohort study, the hazard ratio of COVID-19 among people living in rural areas, in smokers and those in middle socioeconomic status was, 0.37 (0.24, 0.58), 1.50 (1.07, 2.11), as compared to the reference groups. While the hazard ratio of people aged 46-64 and those ≥65 years old, as compared to the reference group within the first year, was 3.47 (1.76, 6.86) and 6.45 (2.80, 14.85), the corresponding value after one year was 2.23 (1.13, 4.40) and 3.52 (1.53, 8.10), respectively. The hazard ratio among those with at least one comorbidity was 2.45 (1.53, 3.92) in the first year of study and after one year decreased to 1.82 (1.14, 2.92). In addition, moderate and vigorous physical activity decreased the hazard ratio. In case-control study the odds ratio of hospitalization increased by 0.03% (1.03(1.01, 1.05)) with an increase of one year in age and in people with at least three comorbidities was 2.43 (1.24, 4.73) times of those without comorbidity.     
Conclusion: Overall, one year after starting the study the decrease in hazard ratio of COVID-19 was significant. Increase in age and having comorbidities are factors that increased the odds ratio of hospitalization. Such people can be considered for the next waves of COVID-19 prioritized for health care and booster vaccination.
