Abstract

  Background & Objectives: Food consumption for its hedonic properties can result in caloric intake exceeding requirements and is considered as a major culprit in the rapidly increasing rate of obesity. We compared the dietary patterns and the hedonic questionnaire score in obese and non-obese women. We also investigated the relation between the score of this questionnaire and variety of food items.

  Methods: This case-control study was conducted on 140 women aged 17-44 years that had referred to obesity club at district 4 of Tehran in 2011. Food intake and hedonic score were determined using validated semi-quantitative 168-item food frequency questionnaire and 21-item hedonic questionnaire, respectively. Logistic regression was used to determine the association between obesity and the dietary patterns identified by factor analysis and hedonic hunger score.

  Results: Two dietary patterns were identified as healthy and unhealthy patterns. The adjusted odds ratio of obesity didn’t show any significant trend in none of the dietary patterns. The mean hedonic questionnaire score was higher in case than control group, significantly (p<0.05). The adjusted odds ratio of obesity, for the second and the third tertiles of this questionnaire versus the first tertile of this, was 2.8 and 10.8, respectively (p<0.05).

  Conclusion: This study shows that there is no difference between the dietary patterns of obese and nonobese women while there is a positive association between hedonic hunger and obesity. It seems that hedonic hunger may lead the obese women to consume unhealthy food choices.

Abstract

 
Infertility, especially in the last decade, has been rising as a global problem, affecting approximately 10-15% of the world's population. The abundance and origin of various types of infertility are different. Studies have shown that reactive oxygen species (ROS) are involved in infertility, in particular in male infertility. Although ROS is essential for normal physiological functions of sperm such as capacitation, hyper activation, acrosome reactions, and binding to the oocyte, excessive levels can be one of the main causes of defective sperm function, which not only impairs the health of sperm DNA, but also affects fertilization via oxidation of proteins, in particular the fatty acids of the sperm cell membrane. Also, the elevated ROS levels facilitate sperm DNA damage, which leads to activation of apoptotic pathway and cell death. Therefore, the quality of semen is functionally reduced. Since the oxidative damage to sperm DNA is associated with both miscarriage and development abnormalities in the offspring, it is essential to find new strategies to recognize the cellular and molecular biology of sperm. Therefore, considering different mechanisms of oxidative stress affecting sperm can contribute significantly to the etiology of male infertility

Abstract

Background & objective: Despite of significant advances in medicine, infectious diseases still threaten the health of society.

The main goal of this research is to study the factors affecting interactive patterns between couples in the Corona period according to the conditions of the disease and home quarantine.
Methods: This study is a qualitative research and was done by Phenomenological method. The Participants included 15 men and women coronavirus survivors in 2020 that were selected by targeted sampling method. Semi-structured interviews were used to collect data.
Results: This research findings indicated that 5 main themes included: Changing roles, experiencing negative emotions, Coping behaviors, Support and Communication problems and 22 sub-themes.

Abstract

Background & Objectives: Early warning scores are commonly used by hospital care teams to assess patients and diagnose early signs of their deterioration and initiate further treatment. Due to the existing studies and the lack of sufficient evidence for burned patients, we decided to investigate the value of initial NEWS and MEWS in predicting mortality in burned patients.
Methods: After obtaining permission from the Ethics Committee of TUMS, patients who were candidates for hospitalization in the burn wards of Sina Hospital from July to March 1998 were included. All demographic information including age, sex, APACHE Type of discharge, comorbidities, percentage of burns, initial hospitalization in the burn ward, type and time of initiation and duration of antibiotic use, amount of serum and NEWS and MEWS scores for all patients were enrolled immediately after admission to the ward as well as before discharge from the ward. Data were analyzed after registration in SPSS software version 23.
Results: In this study, 80 cases of burned patients were studied with a mean age of 37.94±18.85 years. The initial NEWS and MEWS indices have a good ability to diagnose burned patients (Area=0.79 and 0.78, p<0.001). The best cut- point based on the Youden index, for the initial NEWS and MEWS indices were obtained at 4.50 and 1.50, respectively.
Conclusion: In this study, for the first time, NEWS and MEWS were examined in predicting mortality in burned patients and it was found that these criteria can predict the prognosis of burned patients.
