Background:
The promoter methylation and single nucleotide polymorphisms (SNPs) affect the transcription activity of cancer-related genes in several cancers including diffuse gastric cancer (DGC). Here we aimed to evaluate the promoter methylation status and the rs16260 at the promoter region of the CDH1 gene in DGC.
Methods:
This case-control study was performed of 48 formalin-fixed paraffin-embedded (FFPE) blocks of DGC patients and 41 fresh frozen tissue samples of healthy individuals. Methylation status was evaluated using methylation-specific polymerase chain reaction (PCR) and the rs16260 at the promoter region of the CDH1 gene was assessed using PCR and sequencing method.
Results:
The occurrence of methylation at the promoter region of the CDH1 gene in DGC patients was significantly higher than control samples (
P
< 0.0001). The methylated status was significantly associated with the poor differentiated histological type of DGC (
P
= 0.0428). The frequency of AC genotype and the A allele in DGC patients was significantly higher than the control subjects (
P
= 0.006 and 0.003, respectively).
Conclusions:
Here we showed that methylation at the CDH1 promoter may contribute to the DGC development, and also the AC genotype was associated with the risk of DGC.

Evaluation of psychometric properties of NutriCHEQ in Iranian toddlers

DOI
:10.4103/ijpvm.IJPVM_81_20
Background:
Although poor dietary habits have a great effect on the health status of children, especially in toddlers, a few questionnaires exist for the assessment of dietary imbalances. This study aims to assess the validity and reliability of the NutriCHEQ in Iranian healthy toddlers.
Methods:
In this cross-sectional study, first, the NutriCHEQ was translated to Persian and culturally adapted by the forward–backward translation technique. In order to assess the face validity, we used a cognitive interviewing technique of 25 parents/caretakers of healthy toddlers. In the next step, experts assessed content validity, respectively. One item was removed during the content validity process. Then, a blueprint of NutriCHEQ was distributed among 156 parents/caretakers of healthy toddlers in different focal points in Tehran for assessing construct validity by nonlinear principal components analysis. In addition, the anthropometric indices checklist and Food Frequency Questionnaire (FFQ) were filled out for toddlers. Then, construct validity was assessed. The Varimax rotation ran for two sections separately. The four-factor structure was confirmed.
Results:
The model showed a good fit, and all the extracted variance of four factors were satisfactory (F1 = 20.77; F2 = 22.30; F3 = 14.75; and F4 = 13.71). All of the extracted items of the NutriCHEQ in two parts showed 71.53% cumulative variance. For criterion-related validity, there was a statistically significant positive correlation between the NutriCHEQ and Z-score (rho = 0.632,
P
< 0.001). The Bland-Altman result indicates 95% limits of agreement between the NutriCHEQ questionnaire and Z-score.
Conclusions:
Therefore, we concluded that NutriCHEQ is a valid, reliable, and convenient instrument to identify the Iranian toddlers' nutritional status. Therefore, it can be used for research and clinical settings.

Studying the effect of garlic consumption and endurance training on serum levels of some pro-and anti-inflammatory cytokines in female mice with breast cancer - A randomized trial
Mansour EnayatJazi, Fahimeh Esfarjani, Jalil Reisi, Seyed Jamal Moshtaghian
Int J Prev Med
2022, 13:38 (12 March 2022)
DOI
:10.4103/ijpvm.IJPVM_315_20
Background:
This study aimed to determine the effect of garlic consumption and endurance training on the serum levels of some pro-inflammatory and anti-inflammatory cytokines in female mice with breast cancer.
Methods:
This study is an experimental research randomly conducted on 32 female BALB/c mice divided into 4 equal groups (
N
= 8), including: Cancer Control (CC), Garlic Supplementation (GS), Endurance Training (ET), Endurance Training + Garlic Supplementation (ET + GS). One million cancerous cells were injected to all mice's upper right thigh using the subcutaneous injection method. Exercise groups performed endurance training for 8 weeks (5 days a week .(Garlic supplement groups received 1 ml of the garlic extract orally per kilogram of body weight. The control groups -were not given any task, activity or exercise during the research. At the end of the research, all the mice were anesthetized, and their blood samples were collected.
Results:
The period of 8-week simultaneous endurance exercise and consumption of garlic supplement significantly decreased the serum level of interleukin-6 (
F
= 75
P
= 0.00), interleukin-8 (
F
= 97.9
P
= 0.00), and interleukin-17 (
F
= 95.7
P
= 0.00), and increased the serum level of interleukin-10 (
F
= 50.4
P
= 0.00).
Conclusions:
Along with other existing methods, reduction of inflammatory factors, endurance exercises and consumption of garlic supplement have been proved to be an extremely effective treatment for breast cancer patients.
