Digital technologies are being increasingly utilized in healthcare to provide pertinent and timely information for primary prevention, such as vaccination. This study aimed to conduct a systematic review to describe and assess current digital health interventions to promote HPV vaccination among adolescents and parents of adolescents, and to recommend directions for future interventions of this kind. Using appropriate medical subject headings and keywords, we searched multiple databases to identify relevant studies published in English between 1 January 2017 and 31 July 2022. We screened and selected eligible studies for inclusion in the final analysis. We reviewed a total of 24 studies, which included interventions using text messages (4), mobile apps (4), social media and websites (8), digital games (4), and videos (4). The interventions generally improved determinants of HPV vaccination, such as HPV-related knowledge, vaccine-related conversations, and vaccination intentions. In particular, text message and social media interventions targeted improved vaccine uptake behaviors, but little meaningful change was observed. In conclusion, digital health interventions can cost-effectively provide education about HPV vaccination, offer interactive environments to alleviate parental vaccine hesitancy, and ultimately help adolescents engage in HPV vaccine uptake.

Background: This study aimed to investigate the effect of the time from diagnosis to breast cancer surgery on breast cancer patients’ prognosis. Methods: Of the 1900 patients diagnosed with invasive (stage 1–3) breast cancer who underwent surgery in KUH between 2012 and 2019, 279 patients were enrolled in this study. All patients, including those who received neoadjuvant chemotherapy, were classified as Model 1 subjects, and those who received immediate surgical treatment were classified as Model 2 subjects. We conducted a Cox regression analysis to identify prognostic factors of breast cancer associated with the time from diagnosis to surgery. Results: The univariate results indicated a sharp drop in both groups’ survival rates when the time to surgery was delayed for more than 8 weeks (Model 1 p = 0.000; Model 2 p = 0.001). In the multivariate analysis, the hazard ratio (HR) of Model 1increased (HR = 6.84, 95% CI 1.06–44.25) in response to a delay in surgery of more than 8 weeks. Smoking and the American Joint Committee on Cancer (AJCC) staging system had a negative effect on breast cancer prognosis, while hormone therapy had a positive effect. Conclusion: For all patients, a delay in breast cancer surgery of more than 8 weeks was inversely associated with survival.

Background: mHealth, which encompasses mobile health technologies and interventions, is rapidly evolving in various medical specialties, and its impact is evident in oncology. Mobile technologies are perceived as effective in prevention and as feasible for managing skin cancer, but the diagnostic accuracy of these tools remains in doubt. These drawbacks in the application of mHealth to teledermatology call for intensified research to strengthen its role in dermatology. Objective: The purpose of this review was to describe current trends in research addressing the integration of mHealth into the management of skin cancer by examining evaluations of mHealth and its contributions across the cancer care continuum. Methods: A systematic review framework was applied to the search using the three electronic databases, PubMed, Web of Science, and Embase. We extensively reviewed appropriate studies regarding skin cancer and mobile technology published between 2000 and present. Studies were included if they discussed the role and impact of mobile technology in the management and evaluation of skin cancer. 33 studies were selected for analysis adhering to inclusion and exclusion criteria. Results: Of the 33 studies, 15 studies (45%) assessed the diagnostic accuracy of mobile technology in detecting skin cancer and ten studies (30%) examined the feasibility and acceptability of mobile technology. The remaining studies (24%) concerned skin cancer prevention, early diagnosis, reduced treatment, and follow-up care through mHealth interventions. Not all phases of skin cancer involve mHealth, and not all have been addressed by research. While the focus of current research was skewed toward prevention and diagnosis phases, the treatment and follow-up phases were the least addressed in the literature. Conclusions: The present review extends knowledge not only on the contributions but also on the integration of mHealth technologies in different phases of skin cancer care. To optimize the effectiveness of mHealth in dermatology, larger numbers of robust, evidence-based studies on teledermatology implementations, evenly distributed across the care continuum, should be conducted so that research can be expanded to systematic reviews.

The mechanism for reduced voluntary water intake during water immersion was studied in eight men (19–25 yr of age) immersed to the neck while sitting for 3 h at 34.5 degrees C or in air at 28 degrees C when euhydrated (Eu-H2O and Eu-air, respectively) and hypohydrated (Hypo-H2O and Hypo-air) by 3.6% body weight loss. Thirst sensations (degree of thirst, mouth dryness and taste, drinking desirability, and stomach fullness) were similar at the beginning of Hypo-air and Hypo-H2O test periods. Initial drinking of tap water (15 degrees C) was 216 +/- 30 ml/7 min (P less than 0.05) with Hypo-air, decreased to 108 +/- 28 ml/7 min (P less than 0.05) with Hypo-H2O, and was 10–50 ml/10–30 min thereafter. Intake was less than 10 ml/10–30 min in Eu-air, and there was no drinking in Eu-H2O. Within the first 10 min of immersion, compared with Hypo-air findings, the significant reduction in drinking in the Hypo-H2O experiment was associated with unchanged plasma Na+, plasma osmolality, heart rates, and mean arterial pressures; the different responses were increased cardiac output, plasma volume, and atrial natriuretic peptides and decreased plasma renin activity and arginine vasopressin. Thus the extracellular pathway, as opposed to the osmotic pathway, appears to be the major mechanism for immersion-induced suppression of drinking.

Human Papillomavirus (HPV) vaccination is of paramount importance to reduce HPV-associated cancers in both genders. In South Korea, the prophylactic vaccine is recognized as prevention of cervical cancer with little attention given to male HPV vaccination. The purpose of this study was to explore perceptions of male HPV vaccination and underlying factors for vaccine hesitancy among mothers of unvaccinated boys in Seoul, Korea using a qualitative method. We used a purposive sampling strategy to recruit mothers of unvaccinated middle school-aged boys living in one of the 25 districts in Seoul, supplemented by a snowball sampling approach. We conducted one-on-one telephone interviews with ten mothers using a semi-structured interview guide. Questions probed mothers’ views on vaccinating boys against HPV and the reasons for not vaccinating their sons. We found that mothers were hesitant to vaccinate their sons against HPV due to high out-of-pocket costs, fear of side effects concerning the young age of their sons, and low awareness of HPV and HPV vaccine, all of which stemmed from the exclusion of male HPV vaccination in the national immunization program. Sociocultural factors, including vaccination norms, lack of HPV education, and values associated with sexually transmitted infections were also likely to negatively impact mothers’ vaccination decision-making. Despite the barriers, mothers were willing to accept HPV vaccination when it was framed as cancer prevention for not only the sons but also their future spouses. In conclusion, reasons for Korean mothers’ hesitancy for their sons’ HPV vaccine uptake were multifaceted. Healthcare providers’ role in emphasizing and conveying the importance of gender-neutral HPV vaccination will be essential to alleviate negative sentiments around the vaccine for boys and reduce their risk of compromised sexual health. As an effective public health strategy, tailored cancer prevention messages should be delivered heightening significant benefits of the HPV vaccine beyond the prevention of cervical cancer.

School nurses are uniquely positioned to educate students about immunizations, including human papillomavirus (HPV) vaccination, but schools are often without a nurse for different reasons. In lieu of nurses, teachers who closely interact with students and are traditionally well-trusted by parents may be able to communicate about HPV vaccination, alleviating parental vaccine hesitancy. This systematic review explores school teachers’ perspectives on adolescent HPV vaccination and factors influencing their willingness to make vaccine recommendations. We searched three databases with appropriate medical subject headings and keywords to identify relevant studies. We reviewed fifteen studies and provided an extensive summary and a comparison of the results across the studies. Teachers had low to moderate levels of HPV knowledge with low self-efficacy to counsel parents about the HPV vaccine and expressed concerns about the vaccine condoning adolescent sexual activity, vaccine side effects, and parental disapproval. Nonetheless, some teachers showed interest in learning about vaccine effectiveness in preventing HPV-associated cancers and wanted guidance on vaccine communication with parents, viewing schools as adequate venues to promote and deliver HPV vaccines. Schools should consider educating teachers on HPV and HPV vaccination, with a focus on effective vaccine communication practices to increase adolescent HPV vaccine uptake.
