  • The present study aimed at investigating the strengths and weaknesses of a mobile personal health record (PHR) application and identifying its impacts on consumer health information behavior. For the study, twenty-seven college students used a PHR application for three months, based on which the study conducted paper-based interviews with them. The results of content analysis highlighted the benefits of the PHR such as supporting preventive healthcare and motivating and providing specific guidelines for healthy lifestyles by utilizing visual interface design, sharing the data with family and assisting caregivers to manage patients' healthcare, and above all enhancing the interaction between patients and healthcare professionals. However, the study found the drawbacks of the PHR such as a lack of data entry for strength training and the incompatibility with other healthcare applications. The participants were motivated to change their health behaviors in ways such as getting rid of sleep disorders, avoiding alcohol and smoking tobacco, and losing weight, and changing eating habits. Some consumers improved self-efficacy by changing their health behaviors, while the PHR provided emotional supports to the consumers who wanted to improve their health. The present study has an academic significance because the study of PHR is a burgeoning area in Korea. The study provides insights for promoting health and medical information services to cope with the paradigm shift of healthcare fields.

  • Background: Oral cancers account for approximately 2% of all cancers diagnosed each year; however, the vast majority (80%) of the affected individuals are smokers whose risk of developing a lesion is five to nine times greater than that of non-smokers. Tobacco smoke contains numerous carcinogens that cause DNA damage, including oxidative lesions that are removed effectively by the base-excision repair (BER) pathway, in which poly (ADP-ribose) polymerase 1 (PARP-1), plays key roles. Genetic variations in the genes encoding DNA repair enzymes may alter their functions. Several studies reported mixed effects on the association between PARP-1 variants and the risk of cancer development. Till now no reported studies have investigated the association between PARP-1 variants and oral squamous cell carcinoma (OSCC) risk in an Indian population. Materials and Methods: In the present case control study 100 OSCC patients and 100 matched controls were genotyped using PARP1 single nucleotide peptides (SNP's) rs1136410 and rs3219090 using TaqMan assays. Results: The results indicated significantly higher risk with PARP1 rs1136410 minor allele "C" (OR=1.909; p=0.02942; CI, 1.060-3.439). SNP rs1136410 also showed significantly increased risk in patients with smoking habit at C/C genotype and at minor allele C. Conclusions: The PAPR-1 Ala762Val polymorphism may play a role in progression of OSCC. Larger studies with a greater number of samples are needed to verify these findings.

  • Objectives: The average alcohol consumption per capita among Vietnamese adults has consistently increased. Although alcohol-related disorders have been extensively studied, there is a paucity of research shedding light on this issue among Internet users. The study aimed to examine the severity of alcohol-related disorders and other associated factors that might predispose individuals towards alcohol usage in a sample of youths recruited online. Methods: An online cross-sectional study was conducted with 1,080 Vietnamese youths. A standardized questionnaire was used. Respondent-driven sampling was applied to recruit participants. Multivariate logistic and Tobit regressions were utilized to identify the associated factors. Results: About 59.5% of the males and 12.7% of the total youths declared that they were actively using alcohol. From the total sample, a cumulative total of 32.3% of the participants were drinking alcohol, with 21.8% and 25.0% of the participants being classified as drinking hazardously and binge drinkers, respectively. The majority of the participants (60.7%) were in the pre-contemplative stage. Conclusions: A high prevalence of hazardous drinking was recognized among online Vietnamese youths. In addition, we found relationships between alcohol use disorder and other addictive disorders, such as tobacco smoking and water-pipe usage. Our results highlighted that the majority of the individuals are not receptive to the idea of changing their alcohol habits, and this would imply that there ought to be more government effort towards the implementation of effective alcohol control policies.

  • Background: Sperm DNA damage is underlying aetiology of poor implantation and pregnancy rates but also affects health of offspring and may also result in denovo mutations in germ line and post fertilization. This may result in complex diseases, polygenic disorders and childhood cancers. Childhood cancer like retinoblastoma (RB) is more prevalent in developing countries and the incidence of RB has increased more than three fold in India in the last decade. Recent studies have documented increased incidence of cancers in children born to fathers who consume alcohol in excess and tobacco or who were conceived by assisted conception. The aetiology of childhood cancer and increased disease burden in these children is lin ked to oxidative stress (OS) and oxidative DNA damage( ODD) in sperm of their fathers. Though several antioxidants are in use to combat oxidative stress, the effect of majority of these formulations on DNA is not known. Yoga and meditation cause significant decline in OS and ODD and aid in regulating OS levels such that reactive oxygen speues meditated signal transduction, gene expression and several other physiological functions are not disrupted. Thus, this study aimed to analyze sperm ODD as a possible etiological factor in childhood cancer and role of simple life style interventions like yoga and meditation in significantly decreasing seminal oxidative stress and oxidative DNA damage and thereby decreasing incidence of childhood cancers. Materials and Methods: A total of 131 fathers of children with RB (non-familial sporadic heritable) and 50 controls (fathers of healthy children) were recruited at a tertiary center in India. Sperm parameters as per WHO 2010 guidelines and reactive oxygen species (ROS), DNA fragmentation index (DFI), 8-hydroxy-2'-deoxy guanosine (8-OHdG) and telomere length were estimated at day 0, and after 3 and 6 months of intervention. We also examined the compliance with yoga and meditation practice and smoking status at each follow-up. Results: The seminal mean ROS levels (p<0.05), sperm DFI (p<0.001), 8-OHdG (p<0.01) levels were significantly higher in fathers of children with RB, as compared to controls and the relative mean telomere length in the sperm was shorter. Levels of ROS were significantly reduced in tobacco users (p<0.05) as well as in alcoholics (p<0.05) after intervention. DFI reduced significantly (p<0.05) after 6 months of yoga and meditation practice in all groups. The levels of oxidative DNA damage marker 8-OHdG were reduced significantly after 3 months (p<0.05) and 6 months (p<0.05) of practice. Conclusions: Our results suggest that OS and ODD DNA may contribute to the development of childhood cancer. This may be due to accumulation of oxidized mutagenic base 8OHdG, and elevated MDA levels which results in MDA dimers which are also mutagenic, aberrant methylation pattern, altered gene expression which affect cell proliferation and survival through activation of transcription factors. Increased mt DNA mutations and aberrant repair of mt and nuclear DNA due to highly truncatred DNA repair mechanisms all contribute to sperm genome hypermutability and persistant oxidative DNA damage. Oxidative stress is also associated with genome wide hypomethylation, telomere shortening and mitochondrial dysfunction leading to genome hypermutability and instability. To the best of our knowledge, this is the first study to report decline in OS and ODD and improvement in sperm DNA integrity following adoption of meditation and yoga based life style modification.This may reduce disease burden in next generation and reduce incidence of childhood cancers.

  • Objectives: This study evaluated the status of Health-related Behavior in residents from rural areas. A self-administered questionnaire was given to 1,754 people (men; 633 persons, women; 1,121 persons) in rural areas aged over 30 years and under 80 years in Buk-myeon, Uljin-gun and Gigye-myeon, Pohang-si, Gyeongsangbuk-do in 2001 and 2002. Methods: The collected data was analyzed using a chi-square test after an age-adjusted and a chi-square trend test. The data was analyzed using a SPSS/win ver. 10.0. Results: The age-adjusted prevalence of the individual unhealthy behavior according to sex was 56.1% in men and 6.8% in women with regard to smoking; 65.4% and 21.6% with regard to drinking; 72.6% and 76.6% with regard to non-exercise on a regular basis; 23.3% and 28.2 with regard to an obese body mass index; 61.5% and 71.1% with regard to non-scaling in the dental service. The rate of alcohol and tobacco consumption increased with increasing age in both men and women (p<0.01). The age-adjusted proportion in the non-screening examination for stomach cancer according to sex was 49.3% in men and 51.4% in women; 64.0% and 70.7% in liver cancer; 88.9% and 87.5% in colon cancer; 58.3% and 59.1% in undergoing a medical health screening. Conclusions: It is essential for health educators to promote Health-related Behavior in residents in rural areas. In addition, it is expected that the health status of residents in rural areas will improve through efforts to encourage them to take more interest in a healthier lifestyle.
