To investigate the relationship between the timing of energy intake and obesity. Methods: A cross-sectional study was conducted between September 2018 and December 2018. A total of 450 Saudi female students from the University of Tabuk, Tabuk, Saudi Arabia were recruited. ⋯ Additionally, there was no significant difference between the obese and normal weight groups in the total energy intake per day or the total percentage of energy from fat, carbohydrate, and protein per day. However, the total energy intake for each meal and the percentage of energy from fat, carbohydrate, and protein per meal were significantly different between the groups. Conclusion: The greater intake of energy at dinner was positively associated with obesity, while greater energy intake at breakfast were negatively associated with overweight and obesity.

To investigate the circulating levels of microRNA-34a (miRNA-34a) as a novel non-invasive biomarker of breast cancer (BC). Methods: The case-control study was conducted at the Department of Chemistry and Biochemistry, College of Medicine, Al-Nahrain University, Baghdad, Iraq, from December 2018 to April 2019. Real-time quantitative polymerase chain reaction has been employed to analyze miRNA-34a expression in the samples of serum from 90 participants (30 patients with BC 30 patients with benign breast tumors and 30 control subjects) after RNA extraction and reverse transcription. ⋯ Additionally, we analyzed the receiver operating characteristic curves of various markers, including miRNA -34a, CA15-3, and CEA, to assess the diagnostic power of each marker. Results: The expression of miRNA-34a has been significantly lower in the group of breast cancer compared with that in the group of control, and miRNA-34a expression has been significantly reduced in the group of benign breast tumor compared as that in the group of control. Receiver operating characteristics analysis showed a very good discriminative power of combined miRNA-34a and CA15-3 (specificity=77.7%; sensitivity=83.3% and areas under the curve =0.842) for BC patients. Conclusion: MicroRNA-34a expression is significantly decreased in the patients' serum with the cancer of breast, and miRNA-34a can be employed as a potential non-invasive molecular marker for the early diagnosis of BC.

To assess the prevalence of vaccine hesitancy and its determinants among Saudi parents. In addition, we explored the relationship between vaccine hesitancy and child's immunization status. Methods: A cross-sectional study was conducted using interviews with parents visiting outpatient clinics at King Khalid University Hospital, Riyadh, Kingdom of Saudi Arabia, between July 2017 and October 2018. The strategic advisory group of experts on immunization vaccine hesitancy survey was used. Results: A total of 500 parents were interviewed. ⋯ Negative beliefs toward vaccination seemed to be associated with increase hesitancy and incomplete vaccination status of children. In multivariate analyses, the main factors associated with both parents' hesitancy and incomplete vaccination status were believing that vaccines are ineffective (adjusted odds ratio [AOR]=28, 95% confidence interval [CI]: 7.9-102.3) and believing that vaccines are not important (AOR=27, 95% CI: 5.8-126). Conclusion: Vaccine hesitancy among parents in Kingdom of Saudi Arabia is a concern and is likely to influence the vaccination status of their children. Countering vaccine related concerns must be tailored, particularly in higher-educated groups.

To determine the survival outcomes and to describe the epidemiological characteristics of patients with colorectal cancer (CRC) in western Saudi Arabia. ⋯ Colorectal cancer patients presented to the hospital late in the disease course. This may call for lowering the screening age, increasing awareness programs, and establishing a national screening program.

To assess social media and search engines used to find health information in Saudi patients and their companions and to describe their perceptions, attitudes, and practices. Methods: A cross-sectional study was carried out on 374 patients and their companions at a tertiary care hospital in Riyadh, Saudi Arabia. The data were collected between January and March 2018 using a self-administrated questionnaire adopted from the literature and developed in Arabic. The questionnaire was validated and modified by the researchers to fulfill the purpose of this study. ⋯ The reliability of health information on social media was met for 51% of participants, and 81.4% claimed that the health information obtained was knowledgeable. However, only 29% share their personal health experience with the public on social media. Conclusion: Our findings suggest that the majority of the participants used social media platforms to find information related to their health conditions, while approximately one third received direct medical consultations online. Public awareness to use reputable sources for health information is needed.
