The Histopathological Findings in Appendectomy Specimens in an Iranian Population.

Background: Appendicitis is one of the most common causes of acute abdominal surgeries. The importance of parasitic etiologies in the pathogenesis of appendicitis is not well known in appendectomy specimens on a large scale in southwestern Iran. The current study aimed to retrospectively assess the demographic data and histopathological records of appendicitis in a 28-year period in Fars province, southwestern Iran.

The protection motivation theory for predict intention of COVID-19 vaccination in Iran: a structural equation modeling approach.

Background: Many efforts are being made around the world to discover the vaccine against COVID-19. After discovering the vaccine, its acceptance by individuals is a fundamental issue for disease control. This study aimed to examine COVID-19 vaccination intention determinants based on the protection motivation theory (PMT).

Investigating the Effect of Hearing Aid Use on the Balance Status of Children with Severe to Profound Congenital Hearing Loss Using the Pediatric Clinical Test of Sensory Interaction for Balance.

Background: Since the hearing and vestibular organs are close to each other, the correlation between hearing and balance is one of the principal issues, especially in people with hearing loss.

Purpose: In this study, the effect of the auditory system on human balance performance was investigated by comparing the balance status of hearing-impaired children in the aided and unaided situations.

Research Design: In this cross-sectional study a group of children were assigned the task to compare the balance sways in two aided and unaided situations.

Measurement Invariance and Psychometric Analysis of Oxford Happiness Inventory Scale across Gender and Marital Status.

Background: The Oxford Happiness Inventory (OHI) is a self-report tool to measure happiness. A brief review of previous studies on OHI showed the lack of evaluation of OHI fairness/equivalence in measuring happiness among identified groups.

Methods: To examine the psychometric properties and measurement invariance of the OHI, responses of 500 university students were analyzed using item response theory and ordinal logistic regression (OLR).

Bayesian Spatial Joint Model for Disease Mapping of Zero-Inflated Data with R-INLA: A Simulation Study and an Application to Male Breast Cancer in Iran.

Hierarchical Bayesian log-linear models for Poisson-distributed response data, especially Besag, York and Mollié (BYM) model, are widely used for disease mapping. In some cases, due to the high proportion of zero, Bayesian zero-inflated Poisson models are applied for disease mapping. This study proposes a Bayesian spatial joint model of Bernoulli distribution and Poisson distribution to map disease count data with excessive zeros.

Assessment of Differential Item Functioning in Health-Related Outcomes: A Simulation and Empirical Analysis with Hierarchical Polytomous Data.

Background: The purpose of this study was to evaluate the effectiveness of two methods of detecting differential item functioning (DIF) in the presence of multilevel data and polytomously scored items. The assessment of DIF with multilevel data (e.g.

Human intestinal sarcocystosis in Iran: there but not seen.

Human sarcocystosis is a rare infection caused by the genus Sarcocystis who human serve as definitive (intestinal form of infection) host or intermediate (extraintestinal form) host for some various Sarcocystis species. The detection of Sarcocystis oocysts/sporocysts in the feces usually incidentally and is achieved by microscopic examination of the fresh or preserved specimens. To rule out any parasitological etiology among 23,875 (aged 2 months to 95 years) apparently immunocompetent Iranian individuals (from October of 2010 to June of 2016) with abdominal discomforts referred to several teaching hospitals and local clinical laboratories in Fars Province, Iran, their fecal samples were examined using light microscopy.

Knowledge and Attitude about Andropause Among General Physicians in Shiraz, Iran 2014.

Background: Andropause in men refers to the clinical and biochemical syndrome associated with advanced age and characterized by a deficiency in serum testosterone levels. With the increase in aging male population and life span in Iran and focus on quality of life, andropause will become a major health issue that needs to be addressed in order to prevent disability. The results of some research have shown that there is still low level of knowledge and attitude toward andropause among health professionals.

Growth Velocity of Infants From Birth to 5 Years Born in Maku, Iran.

Background: Growth velocity standards are essential for proper evaluation of child growth. The goal of this study was to construct weight, height and head circumference growth velocity charts for infants.

Methods: This study includes 256 infants (124 boys and 132 girls) born in Maku, Northwest of Iran, and monitored from birth until they were 5 years.

Child Weight Growth Chart and Its Associated Factors in Birth Cohort of Maku Using a Growth Curve Model and LMS Method.

Background: Infant growth is defined as a positive change in body size over a period of time, and is a sensitive predictor of social health. The most effective way to determine child growth is by measuring birth weight and constructing a weight growth trajectory. Many studies were conducted on the effects of different factors on birth weight, but investigations of these effects on growth trajectory are really sparse.

Measurement equivalence of the KINDL questionnaire across child self-reports and parent proxy-reports: a comparison between item response theory and ordinal logistic regression.

Measurement equivalence is a necessary assumption for meaningful comparison of pediatric quality of life rated by children and parents. In this study, differential item functioning (DIF) analysis is used to examine whether children and their parents respond consistently to the items in the KINDer Lebensqualitätsfragebogen (KINDL; in German, Children Quality of Life Questionnaire). Two DIF detection methods, graded response model (GRM) and ordinal logistic regression (OLR), were applied for comparability.
