The use of transabdominal color Doppler ultrasound after oral administration of an oral cellulose-based contrast agent (TUS-OCCA) in depicting varices at the cardia and fundus was explored. Both gastroscopy and transabdominal color Doppler ultrasound (TUS) were performed for this purpose, with gastroscopy serving as the gold standard. Patients were assigned by TUS protocol to one of three groups: TUS + empty stomach (TUS-ES); TUS + oral water intake (TUS-OW); and TUS-OCCA. TUS-based grading of varices reflected venous diameters and blood flow velocities, designated as follows: Ux = difficulty discerning gastric fundus and cardia or delineating varices; U0 = no detectable varices; U1 = diameter <5 mm, flow rate <10 cm/s; U2 = diameter <5 mm, flow rate ≥10 cm/s; U3 = diameter 5-10 mm, flow rate <10 cm/s; U4 = diameter 5-10 mm, flow rate ≥10 cm/s; and U5 = diameter >10 mm, any flow rate...

Receiving the HPV vaccine at a young age before being exposed to the virus is essential to improve HPV-related cancer prevention. In many countries in the world, like Italy, the HPV vaccine is offered free of charges to boys and girls aged 12-14. Despite this incentive, the HPV vaccine uptake in Italy remains low. Several interventions and campaigns have been implemented to educate parents and providers. However, children of 12-14 years old have been left out by prevention and education efforts. This study explored middle school children's knowledge and perceptions of the HPV virus and vaccine with the purpose to identify gaps and misperceptions and provide recommendations to develop educational interventions...

Health interventions that use serious games have become increasingly popular. However, many of these games have been designed with few immersive game features which would improve users' engagement with the persuasive messages. To address this issue, researchers have incorporated narrative elements in games to facilitate message processing and enhance behavioral change. There have been theoretical debates about whether narratives benefit these interventions; empirical evidences for their effects are slightly mixed...

Uncertainty in the context of cancer involves a complex and conflicting decision-making process. Individual preferences of seeking or avoiding information in the decisions of maintaining, reducing, or increasing uncertainty often depend on key cancer-related beliefs. The present study investigates whether cancer worry (CW), information overload (CIO), or fatalism (CF) can predict four constructs of uncertainty management preferences - avoid to maintain hope, avoid insufficient information, seek to increase uncertainty, and seek to reduce uncertainty...

Health communication experts continually seek out effective strategies to strengthen persuasive campaigns. While there is evidence that verbal metaphors can improve persuasion, little attention has been given to the potential of visual metaphors to enhance health communication effects. To fill this gap, an experiment was conducted to test the effects of metaphor modality (visual vs. verbal) and type of fear appeal used (death-based or appearance-based) on skin protection intentions. Additionally, the moderating role of an individual characteristic (need for cognition), and the mediating role of two processing outcomes (message elaboration and perceived message effectiveness) were examined...

Enrollment rates of cancer clinical trials remain low, affecting the delivery of effective medical treatments. Recent research has documented common factors affecting trial participation, but to improve these efforts more studies are needed to further understand specific concerns and issues of potential participants in multiple contexts. Forums and other online peer-to-peer health communities are crucial to the coping and survivorship of cancer patients. Online health communities will offer valuable information to understand how patients discuss perceptions, motivations, and challenges associated with clinical trial participation, and to understand how patients provide support to each other...

Enrollment rates for cancer clinical trials remain low, affecting the generalizability of new treatments. Research shows that many patients face significant challenges in understanding basic clinical trial vocabulary and making informed decisions about participation. Informational aids (IA) are developed to address these challenges and support decision making of cancer clinical trial participation. The present study proposed and tested a structural path model to explain the efficacy of three (i.e., interactive, non-interactive, non-cancer control) IAs...

Cancer is the uncontrollable abnormal division of cell growth, caused due to the varied reasons. Cancer can be expressed in any part of the body, and it is one of the death-causing diseases. Human reproductive organs are commonly damaged by cancer. In particular, the women reproductive system is affected by various cancers including ovarian, cervical, endometrial, vaginal, fallopian tube, and vulvar cancers. Identifying these cancers at earlier stages prevents the damage to the organs. Aptamer is the potential probe that can identify these cancers...

Communicating about clinical trials and medical research is challenging. An appropriate communication is essential to reduce some of the barriers associated with poor patients' enrollment in clinical trials and with patients' uninformed consent or uninformed refusal. An experiment was conducted to assess the effects of educational animations compared to brochures with and without visuals, and with the materials currently used by the NIH. These materials focused on explaining placebos, randomization, the steps necessary to enroll in a clinical trial, and how and by who patients' protection is ensured...

The inclusion of diverse populations in clinical trial research is a social justice imperative. Creating the communicative tools that can support cancer patients across varied cultural backgrounds in processing complex clinical trial information, to achieve informed consent, has been a challenge. This study sought to evaluate specific clinical trial multimedia-a website, four animations, and a decision aid-to meet the decision-making and informational needs of Hispanic patients. The multimedia content was positively evaluated by Hispanic cancer patients...

Perceived social norms are routinely observed as positive predictors of indoor tanning. Past research has suggested that messaging interventions target normative perceptions to reduce indoor tanning behavior. Despite this call, little empirical research has investigated the utility of taking a social norms approach in behavioral interventions. The present study addresses this gap by conducting a quasi-experiment ( N = 206) assessing the effect of an intervention message correcting normative misperceptions on indoor tanning intentions at different levels of tanning frequency...

Clinical trials and research studies often fail to recruit participants from the minorities, hampering the generalizability of results. In order to mitigate this problem, the present study investigated how race/ethnicity affects the process of recruiting people from racial and ethnic minority groups, by conducting 11 focus groups with professional recruiters. Several themes emerged, such as how to adapt to potential participants' language competency and literacy levels, the importance to engage in culturally appropriate verbal and non-verbal communication, and to establish a sense of homophily between recruiters and patients...

In order to advance medical care, it is necessary to invest resources, both human and financial, in medical research. However, these investments sometimes are not sufficient to ensure the success of research studies. No progress can be made without the participation of patients in research studies and clinical trials. These potential participants are normally identified by their physicians, or by professional recruiters, depending on the patient clinical profile. However, often patients are intimidated by the idea of engaging in clinical trials for several reasons, including the fear of side effects, to the difficulty of understanding specific research-related terms...

BACKGROUND: HIV-related mHealth interventions have demonstrable efficacy in supporting treatment adherence, although the evidence base for promoting HIV testing is inconclusive. Progress is constrained by a limited understanding of processes used to develop interventions and weak theoretical underpinnings. This paper describes a research project that informed the development of a theory-based mHealth intervention to promote HIV testing amongst city-dwelling African communities in the conditions...

Few studies have examined the communication behaviors of those who recruit for clinical trials and research studies, particularly of nonmedical professionals who often do the bulk of recruiting. This focus-group study of 63 recruiters analyzes the ways in which nonverbal communication behaviors support the process of recruitment, using the lens of communication accommodation theory. Results indicate that recruiters first "read" potential study participants' nonverbal communication for clues about their state of mind, then use nonverbal communication to achieve a sense of convergence...

The lack of accrual to research studies and clinical trials is a persistent problem with serious consequences: Advances in medical science depend on the participation of large numbers of people, including members of minority and underserved populations. The current study examines a critical determinant of accrual: the approach of patients by professional recruiters who request participation in research studies and clinical trials. Findings indicate that recruiters use a number of verbal strategies in the communication process, including translating study information (such as simplifying, using examples, and substituting specific difficult or problematic words), using linguistic reframing or metaphors, balancing discussions of research participation risks with benefits, and encouraging potential participants to ask questions...

Polycyclic aromatic hydrocarbons (PAHs) contamination was investigated in concurrently sampled surface water, suspended particulate matter (SPM) and sediment of Daliao River estuary and the adjacent area, China. The total concentrations of PAHs ranged from 71.12 to 4255.43 ng/L in water, from 1969.95 to 11612.21 ng/L in SPM, and from 374.84 to 11588.85 ng/g dry weight (dw) in sediment. Although the 2-3 ring PAHs were main PAH congeners in water and SPM, the 4-6 ring PAHs were also detected and their distribution was site-specific, indicating a very recent PAHs input around the area since they were hydrophobic...
