We aimed to explore the correlation between the time and risk preferences and the smoking behavior of adult population in western Iran.
Overall, 792 individuals with the age of 35 to 65 yr participating in an ongoing national cohort study (Persian Cohort) were approached to complete a pre-structured questionnaire in 2017. Time preferences were measured using a standard choice-based method. The individuals' discount rates were identified by questions that offered binary monetary choices on immediate future and distant future, by making trade-offs between them. Probit regression model was used to investigate the relationship between time preferences and smoking when controlling for demographic and socioeconomic variables.
Time and risk preferences had statistically significant direct correlations with smoking. A unit increase in discount rate was associated with a 4.4% percentage point increase in the likelihood of being smoker. A present-biased individual had 5.7% percentage points lower likelihood of being smoker. Moreover, a unit increase in willingness to take the risk increased the likelihood of being a smoker by 1.5% percentage points.
Time and risk preferences are important determinants of smoking behavior. These factors should be considered in designing effective prevention and control programs. SB-3CT supplier Policies that increase the immediate costs of cigarette smoking or the immediate benefits of smoking cessation are likely to have a greater impact on reducing the prevalence of cigarette smoking.

The prevalence of HIV/AIDS has been increasing in Iran, especially amongst the young population, recently. The joint model (JM) is a statistical method that represents an effective strategy to incorporate all information of repeated measurements and survival outcomes simultaneously. In many theoretical studies, the population under the study were heterogeneous. This study aimed at comparing three approaches by considering heterogeneity in the patients.
This study was conducted on 750 archived files of patients infected with HIV in Fars Province, southern Iran, from 1994 to 2017. Proposed Approach (PA), Joint Latent Class Models (JLCM), and Separated Approach (SA) were compared to evaluate the influence covariates on the longitudinal and time-to-event outcomes in the heterogeneous HIV/AIDS patients.
Gender (
<0.001) and HCV (
<0.01) were two significant covariates in the classification of HIV/AIDS patients. Time had a significant effect on CD4 (
<0.001) in both classes in the three approaches. In PA and SA, females had higher CD4 than males (
<0.001) in the first class. In JLCM, females had higher CD4 than males (
<0.01) in both classes. The patients with higher Hgb had also higher CD4 (
<0.001) in both classes in the three approaches. HCV reduced the CD4 significantly in both classes in PA (
<0.05) and SA (
<0.001). Within the survival sub-model, HCV reduced survival rate significantly in the second class in PA (
<0.05), JLCM (
<0.01) and SA (
<0.001).
PA was an appropriate approach for joint modeling longitudinal and survival outcomes for this heterogeneous population.

The purpose of this study was to investigate the role of eotaxin family members including C-C motif chemokine 11 (CCL11), C-C motif chemokine 24 (CCL24), and C-C motif chemokine 26 (CCL26) as the subgroups of CC-chemokine in patients affected with osteoporosis and osteopenia.
Overall, 19 osteoporotic patients, 18 osteopenic individuals, and 20 healthy subjects were recruited in this study. The bone mineral density (BMD) was then measured at the lumbar spine (L1-L4) and the hip (femoral neck and total hip) using dual-energy X-ray absorptiometry for diagnosis of bone density and related disorders. Additionally, enzyme-linked immunosorbent assay (ELISA) technique was employed to measure the serum levels of CCL11, CCL24, and CCL26.
The circulating levels of CCL11, CCL24, and CCL26 had been increased in both groups of patients with osteopenia and osteoporosis compared to those in healthy subjects (
<0.05); while no significant difference was observed between serum levels of these chemokines in such patients.
Eotaxins can play a role in the pathogenesis of osteoporosis and osteopenia; however, further studies are needed to clarify various roles of eotaxins in the pathophysiology of osteoporosis and osteopenia.

Human
a cyclo-zoonotic infection caused by tapeworms of the
sensu stricto complex. The detection of mitochondrial genome data of genus
can reflect the taxonomic status, genetic diversity, and population structure genetics.
Totally, 52 formalin-fixed paraffin-embedded (FFPE) tissue samples from patients with histologically confirmed CE were collected from Mazandaran province, Iran in the period of Mar 1995 to May 2018. All extracted DNAs from (FFPE) tissue samples were subjected to amplify by polymerase chain reactions method targeting cytochrome c oxidase subunit 1 (
) gene. All PCR amplicons were sequenced to phylogenetic analysis and genetic diversity.
Molecular analysis showed that 50(96.1%) and 2 (3.84%) isolates were identified as G1 andG3
genotypes, respectively. DNA sequence analyses indicated a high gene diversity for G1 (Haplotype diversity 0.830) and G3 genotypes (Hd 1.00). Based on multiple sequence alignment analyses, 7 (13.46%; G1 genotype) and 2 (3.84%; G3 genotype) new haplotypes were unequivocally identified.
G3 genotype (Buffalo strain) was identified from two human hydatidosis isolates in the region. Present study strengthens our knowledge about taxonomic status, transmission patterns of
parasite to human and heterogeneity aspects of this parasite in clinical CE isolates of Northern Iran.
