RESUMEN

BACKGROUND: To investigate the clinical effects and safety of the hybrid debranching technique for patients with acute Stanford type A aortic dissection (AD). METHODS: One hundred nine patients with acute Stanford type a AD were selected and divided into observation group and control group according to the different surgical methods. Fifty-five patients in the observation group were treated with hybrid debranching, and 54 patients in the control group were treated with Sun's operation. The operation duration, clamp time, cardiopulmonary bypass duration, volume of blood transfusion, ventilator application duration, duration of stay in the intensive care unit, aortic rupture, second thoracotomy due to hemorrhage, gastrointestinal hemorrhage, stroke, paraplegia, renal failure, and all-cause mortality were recorded. Postoperative follow-up was conducted. The number of cases that underwent follow-up and the number of cases with complete thrombosis of the false aneurysm cavity detected by computed tomography angiography (CTA) was recorded. RESULTS: The surgical success rate was 100% in both groups, and there were no cases with unplanned secondary surgery. Compared with the control group, only the difference in the volume of blood transfusion was not significantly significant between the two groups (P = 0.052), while the rest of the observation indicators were significantly lower in the observation group than in the control group (P < 0.001 for all). The proportion of cases with complete thrombosis of the false aneurysm cavity was significantly higher in the observation group than in the control group at 3 and 6 months after surgery (P < 0.05). CONCLUSION: In patients with acute Stanford type A AD involving the arch, the hybrid debranching technique was safe and effective. It was recommended for patients with advanced age and a high risk of intolerance to deep hypothermic circulatory arrest.

RESUMEN

BACKGROUND: In the past two decades, melanoma incidence among Hispanic people has risen greatly. This qualitative study explored Hispanic people's perceived barriers and facilitators to skin cancer-related preventive behaviors. METHODS: Five focus groups among Hispanic people (2 in Spanish and 3 in English; n = 34; 11 Spanish-preferring and 23 English-preferring) were conducted, where participants discussed their perceptions and behaviors relating to skin cancer, sun protection, and skin self-examination. Additionally, healthcare providers (n = 9) and Hispanic community leaders (n = 6) were recruited for individual interviews to complement the results of focus groups. A thematic analysis was conducted on all transcripts. RESULTS: Perceived barriers to sun protection included: 1) Low levels of knowledge and awareness/misperception; 2) low perceived importance or not a priority, 3) economic issues or limited access, 4) downsides/concerns about engaging in sun protection behaviors, and 5) Hispanic cultural norms (e.g., machismo). Facilitators to sun protection included: 1) relevance/care for family, 2) negative consequences of sun exposure, and 3) Hispanic cultural norms (e.g., familismo). Barriers to skin examination included: 1) low levels of knowledge and awareness, 2) lack of insurance coverage or access, and 3) difficulty or discomfort associated with practicing skin self-examination. Facilitators to skin examination included: 1) relevance/previous experience and 2) having insurance coverage or access. CONCLUSIONS: Future interventions should focus on individual, community, and system-level strategies to address misperceptions in the Hispanic community, increase knowledge and awareness, address perceptions of cultures regarding skin cancer preventive activities, and emphasize the importance or priority of health issues related to skin cancer.

RESUMEN

Still little is known about possible environmental risk factors of childhood hematological malignancies (CHM). Previous studies suggest that ultraviolet radiation (UVR) exposure is associated with a lower risk of acute lymphoblastic leukemia (ALL) in children. We investigated the association between solar UVR exposure and risk of CHM in Switzerland, a country with greatly varying topography and weather conditions. We included all resident children aged 0-15 years from the Swiss National Cohort during 1990-2016 and identified incident cancer cases through probabilistic record linkage with the Swiss Childhood Cancer Registry. We estimated the overall annual mean UV level and the mean level for the month of July during 2004-2018 at children's homes using a climatological model of the midday (11 am-3 pm) UV-index (UVI) with a spatial resolution of 1.5-2 km. Using risk-set sampling, we obtained a nested case-control data set matched by birth year and fitted conditional logistic regression models (virtually equivalent to analyzing full cohort data using proportional hazards models) adjusting for sex, neighborhood socio-economic position, urbanization, air pollution, and background ionizing radiation. Our analyses included 1446 cases of CHM. Estimated adjusted hazard ratios (HR) per unit increase in UVI in July were 0.76 (95% CI 0.59-0.98) for leukemia and 0.74 (0.55-0.98) for ALL. Results for annual exposure were similar but confidence intervals were wider and included one. We found no evidence for an association for lymphoma overall (HR 1.14, 95% CI 0.59-2.19 for annual exposure) or diagnostic subgroups. Our study provides further support for an inverse association between exposure to ambient solar UVR and childhood ALL.

RESUMEN

BACKGROUND: In the past 2 decades, melanoma incidence among Hispanic individuals has risen by 20%. The mortality rate of Hispanic individuals is higher than that for non-Hispanic White individuals. Skin cancer can largely be prevented with regular sun protection, and skin cancer outcomes can be improved through early detection, for example, by skin self-examination. Alarmingly, Hispanic individuals are less aware of the symptoms and harms of skin cancers, tend to have misperceptions regarding the risks and benefits of skin cancer prevention behaviors, and engage in less sun protection behaviors than non-Hispanic White individuals. OBJECTIVE: This study aimed to use a community-engaged approach and conduct both group and individual interviews among Hispanic individuals and relevant key stakeholders to explore the potential design of a mobile-based skin cancer prevention intervention for Hispanic individuals. METHODS: This study used a qualitative design (focus groups and individual interviews). Participants were recruited from local community organizations' social media, local events, and contact lists (eg, email). Zoom interviews were conducted to examine whether Hispanic individuals would be interested in a mobile-based skin cancer intervention and to explore their preferences and suggestions to inform skin cancer prevention intervention design. RESULTS: Five focus groups (2 in Spanish and 3 in English) among self-identified Hispanic individuals (n=34) and 15 semistructured, in-depth individual interviews among key stakeholders (health care providers and community leaders; eg, dermatologist, nurse practitioner, licensed social worker, and church leader) were conducted. The main themes and subthemes emerging from the group discussions and individual interviews were organized into the following categories: intervention platform, delivery frequency and format, message design, engagement plan, and activities. WhatsApp and Facebook were identified as suitable platforms for the intervention. Messages including short videos, visuals (eg, images and photographs), and simple texts messages were preferred. Recommendations for message design included personalized messages, personal stories and narratives, culturally relevant design (eg, incorporating family values), and community-trusted sources. Potential engagement and retention recommendations were also discussed. Additional details and exemplar quotes of each theme and subtheme are described. CONCLUSIONS: This study provides important insights and directions for the design of a mobile, digital skin cancer intervention to modify Hispanic individuals' sun protection and skin self-examination behaviors to help improve skin cancer outcomes. Insights gathered from community leaders and health care providers provided valuable additions to the community-derived data. Leveraging popular digital platforms among Hispanic individuals such as WhatsApp or Facebook could be a promising approach to skin cancer prevention. Recommendations from the community included the use of concise videos, illustrative images, clear text messages, tailored communications, narratives featuring personal experiences, designs that reflect cultural significance, and information from sources that are trusted by the community, which provided useful strategies for future intervention design among Hispanic individuals.

RESUMEN

BACKGROUND: Agricultural workers are at risk of developing skin cancer due to prolonged exposure to the sun during their daily work. This study was conducted to determine sun protection knowledge and behaviours of agricultural workers in Turkey. METHODS: The cross-sectional study was conducted with 460 participants working in agriculture. The data were collected using a sociodemographic form, Skin Cancer and Sun Knowledge Scale and Sun Protection Behaviour Scale. The data were analysed using One Way ANOVA and Independent Samples t Test. RESULTS: Participants mean total score on the Skin Cancer and Sun Knowledge Scale was 15.24 ± 2.47 (max-min 0-25) and the mean total score on the Sun Protection Behaviour Scale was 24.10 ± 4.46 (max-min 8-40). Statistically significant disparities were observed between the SCBS, SPBS and their sub-divisions along with the working period, age, marital status, gender, level of education, income status, skin type and agricultural working status of the participants (p < .05). CONCLUSION: The study found that people working in the agriculture had inadequate sun protection behaviours and knowledge. Based on the study's results, it is proposed to create intervention programmes that specifically target single, male, middle-aged or older individuals with extended working hours and low levels of education and income.

RESUMEN

Objectives: This study evaluates the feasibility and impact of conveying personalized sun protection message supported by a UV photograph of the face in Switzerland. Methods: 440 adults from 14 private and public sites associated with high sun exposure received a skin cancer prevention intervention composed of a facial UV-filtered photograph and individual counselling by a trained registered nurse. Pre-/post intervention surveys assessed sun protection of participants, their skin cancer risk and reasons for behavioural change. Results: The range of facial UV spots' count per individual was very broad (0-590) and mainly determined by phototype, followed by age. Three months after the intervention, 61% of participants positively changed their sun protection habit both during leisure and at work. Use of all sun protection means increased. No factor could be specifically associated to that propension for change. The individualized message was perceived as the main motivation for change. Conclusion: Personalized sun protection messages supported by a facial UV photograph led to significant favourable behavioural change in a highly sun-exposed population of adults.

RESUMEN

Despite a growing number of young adults developing skin cancers, little is known about the sun-protective behavior of high school athletes exposed to high levels of UV radiation, such as junior tennis players. To investigate the frequency and quality of their sun protective behaviors, a web-based, anonymous survey was conducted among tennis players at high school varsity matches and United States Tennis Association tournaments in Southern California. Although 92.6% of the 81 respondents indicated they play during peak sun intensity hours, 46.9% stated they do not regularly wear sunscreen, 27.2% do not routinely wear hats or visors, only 9.9% wear protective eyewear, and 4.9% wear UV-protective clothing; furthermore, 87.5% of junior tennis players stated they are not very familiar with skin cancer, but 73.8% would like to learn more about it. The results of this study demonstrate a lack of consistent sun protective behavior among junior tennis players, providing a rationale for the development of targeted educational campaigns to increase skin cancer risk awareness and more effective sun-protective behavior.

RESUMEN

BACKGROUND: Ultraviolet (UV) radiation is the most important risk factor for skin cancer development. Sunlight is the main source of UV radiation in the general population. In addition, tanning beds are a source of artificial UV radiation. Since the incidence of skin cancer is increasing worldwide, it is necessary to monitor UV-related risk behaviors such as intentional indoor and outdoor tanning, as well as sun protection behavior in the general population and specific subgroups and settings. This is the aim of the National Cancer Aid Monitoring online (NCAM-online), a continuation and further development of the NCAM. METHODS: The NCAM-online is a longitudinal trend study consisting of four annual survey waves. Each year, 4,000 individuals aged 16-65 years living in Germany will be surveyed using online questionnaires. Each year, intentional indoor and outdoor tanning will be assessed. In addition, varying specific topics regarding skin cancer prevention, such as the utilization of skin cancer screening, will be addressed in the questionnaires. DISCUSSION: The findings of the NCAM-online will provide an important basis for the German Cancer Aid and Working Group on Dermatologic Prevention (Arbeitsgemeinschaft Dermatologische Prävention, ADP) to develop targeted prevention campaigns and projects aimed at preventing skin cancer. The explorative nature of the NCAM-online allows for the identification of new potential starting points for prevention and education. In addition, the longitudinal design allows for a description of the trend in the prevalence of intentional tanning. For tanning bed use, representative trend data from 2012 are available for Germany, to which NCAM-online will add annual data until 2027.

RESUMEN

The rapidly increasing skin cancer rates in Canada are alarming, with current data estimating that 1/3 of Canadians will be affected in their lifetime. Thus, deeper understanding of high-risk sun exposure behaviors is needed to help counter this trend. Only limited action has been taken by federal/provincial governments to reduce skin cancer incidence. A cross-sectional survey study was conducted in Manitoba, with frequency counts, means, and percentages used to encapsulate responses. Age- and gender-adjusted odds ratios were calculated using logistic regression analyses. Our study identified worrying inadequacies in sun protective behaviors and attitudes, with the threat of such high-risk behaviors amplified by a lack of skin cancer awareness. Alarming elements were noted in participants' sun exposure history (>65% reported a history of sunburns, >50% previously used a tanning bed, and >75% recently tanned for pleasure), beliefs and attitudes (>50% believe that they look better/healthier with a tan, and >40% believe that having a base tan is protective against further sun damage), and sun protection efforts (sun protective clothing was used <60% of the time, sunscreen was used by <50%, and there was a lack of knowledge about sunscreen characteristics in ~30% of respondents), in addition to significant differences being established between demographic subgroups (based on gender, age, skin phototype, income, and education attained). This study provides worrisome insight onto the grim landscape of sun protective behaviors and attitudes in Manitoba, which will inevitably translate into higher skin cancer rates and should serve as a call to action to promote targeted public health messaging in this jurisdiction and beyond.

RESUMEN

Objective: The objective of this study is to explore the risk factors associated with new-onset postoperative atrial fibrillation (POAF) following Sun's surgery(total arch replacement using a tetrafurcate graft with stented elephant trunk implantation) for acute type A aortic dissection(AAAD) and to develop a predictive model for assessing the likelihood of new-onset POAF in patients undergoing Sun's surgery for AAAD. Methods: We reviewed the clinical parameters of patients diagnosed with AAAD who underwent Sun's surgery at Qilu Hospital between December 1, 2017 and December 31, 2022. The data was analyzed through univariable and multivariable logistic regression analysis. Variance inflation factor was used to investigate for variable collinearity. A nomogram for predicting new-onset POAF was developed and verified by bootstrap resampling. In addition, the calibration of our model was evaluated by the calibration curve and Hosmer-Lemeshow test. Furthermore, the clinical utility of our model was evaluated using the net benefit curve. Results: This study focused on a cohort of 242 patients with AAAD, among whom 42 experienced new-onset POAF, indicating an incidence rate of 17.36%. Age, left atrial diameter (LA), right atrial diameter (RA), preoperative red blood cells (RBC), and previous acute coronary syndrome (preACS) emerged as independent influences on new-onset POAF following Sun's surgery, as identified by univariable and multivariable logistic regression analysis. Collinearity analysis with demonstrated no collinearity among the variables. A user-friendly prediction nomogram for new onset POAF following Sun's surgery was formulated. The model demonstrated commendable diagnostic accuracy with an area under the curve (AUC) of 0.7852. Validation of the model through bootstrapping (1,000 repetitions) yielded an AUC of 0.8080 (95% CI: 0.8056-0.8104). affirming its robustness. Additionally, the model exhibited favorable fit, calibration, and positive net benefits in decision curve analysis. Conclusions: Drawing upon these findings, we have developed a predictive model for the occurrence of new-onset POAF. These results suggest the potential efficacy of this prediction model for identifying patients at risk of developing POAF. The visualization of this model empowers healthcare professionals to conveniently and promptly assess the risk of AF in patients, thereby facilitating the timely intervention implementation.

RESUMEN

OBJECTIVE: To understand rural older farmers' perspectives and attitudes toward skin cancer risk and prevention. DESIGN AND SAMPLE: This study used a grounded theory approach and semi-structured interviews with 12 rural older farmers (farm owners, farmworkers ages 50 years or older) in Washington. Participants' perspectives were explored relative to Health Belief Model constructs. Inductive and deductive analyses were used to generate relevant themes. COREQ guidelines were followed. RESULTS: The findings fit well and extended the Health Belief Model, which was used to arrange key themes identified in relation to skin cancer risk and prevention, specifically participants' perceived barriers to accessing primary care and protection when outdoors, perceived benefits of sun-protective behaviors, perceived hereditary susceptibility to skin cancer, perceived severity of the increased skin cancer risk, and cues to action for skin checks. A new construct of hope was identified to emphasize the importance of establishing emotional, instrumental, and informational support systems for promoting skin cancer prevention. Participants also indicated their hope of raising awareness of skin cancer prevention among all ages. CONCLUSIONS: Findings highlighted the importance of integrating skin cancer prevention services for rural older farmers and across the lifespan. Public health approaches are needed to enhance the awareness of and access to preventive care in these underserved populations.

RESUMEN

BACKGROUND: Previous studies have noted the link between rosacea severity and quality of life, but there is limited understanding of how disease perception impacts these aspects. Additionally, sun exposure is identified as a common trigger for rosacea flare-ups, emphasizing the importance of sun protection practices in managing the condition. This cross-sectional study aims to fill the gap in the literature by investigating the relationship between clinical severity, disease perception, quality of life, and sun protection behaviors in rosacea patients. METHODS: Questionnaires assessing the quality of life, illness perception, sun protection behaviors, sun protection decisional balance, and its potential predictors were completed by 120 rosacea patients and 120 controls. RESULTS: Patients exhibited a higher prevalence of sun protection behaviors than the control group (24.15 ± 5.76 vs. 17.63 ± 5.56, p < 0.001) and demonstrated greater determination in adhering to sun protection practices (13.43 ± 2.37 vs. 9.40 ± 3.09, p < 0.001). Hierarchical linear regression analyses showed that quality of life was related to clinical severity, illness perception (consequences, illness coherence, emotional representations), causal attribution (risk factors, immunity), and sun protection decisional balance variables (R2 = 0.45, F = 7.39, p < 0.001). Also, the perceived pros and cons of sun protection behaviors were predicted by illness perception (treatment control), causal attribution (risk factors, immunity, chance/accident), and quality of life variables (R2 = 0.24, F = 2.59, p = 0.004). CONCLUSIONS: Providing more information to rosacea patients can improve their disease perception and quality of life, increasing adherence to sun protection behaviors.

RESUMEN

Over the past few decades, corals of the genus Tubastraea have spread globally, revealing themselves to be organisms of great invasive capacity. Their constant expansion on the Brazilian coast highlights the need for studies to monitor the invasion process. The growth, fecundity, settlement, and data on the coverage area of three co-occurring Tubastraea species in the 2015-2016 period were related to temperature variation and light irradiance on the rocky shores of Arraial do Cabo, Rio de Janeiro. Hence, this study sought to understand and compare the current invasion scenario and characteristics of the life history strategy of sun coral species based on environmental variables, considering the uniqueness of this upwelling area in the southwestern Atlantic. For that, we evaluate the fecundity, settlement, and growth rates of corals by carrying out comparative studies between species over time and correlating them with the variables temperature and irradiance, according to seasonality. Field growth of colonies was measured every two months during a sample year. Monthly collections were performed to count reproductive oocytes to assess fecundity. Also, quadrats were scrapped from an area near a large patch of sun coral to count newly attached coral larvae and used years later to assess diversity and percentage coverage. Results showed that corals presented greater growth during periods of high thermal amplitude and in months with below-average temperatures. Only Tubastraea sp. had greater growth and polyp increase in areas with higher light incidence, showing a greater increase in total area compared to all the other species analyzed. Despite the observed affinity with high temperatures, settlement rates were also higher during the same periods. Months with low thermal amplitude and higher temperature averages presented high fecundity. While higher water temperature averages showed an affinity with greater coral reproductive activity, growth has been shown to be inversely proportional to reproduction. Our study recorded the most significant coral growth for the region, an increase in niche, high annual reproductive activity, and large area coverage, showing the ongoing adaptation of the invasion process in the region. However, lower temperatures in the region affect these corals' reproductive activity and growth, slowing down the process of introduction into the region. To better understand the advantages of these invasion strategies in the environment, we must understand the relationships between them and the local community that may be acting to slow down this colonization process.

RESUMEN

Yuling paste, a traditional Chinese health food derived from longan pulp and American ginseng, undergoes a unique processing method involving nine cycles of steaming and sun-drying. Ultra-high-performance liquid chromatography tandem mass spectrometry combined with widely targeted metabolomics has been used to examine the dynamic change in metabolite profiles through the processing. A total of 758 metabolites were identified. Processing significantly affects metabolite changes, and network pharmacology is subsequently used to explore potential pharmacological ingredients. After processing, the contents of active ingredients such as ginsenoside rh2, oleanolic acid, choline, d-glucose, and D-galacturonic acid were found to increase significantly. These increases can be correlated to the enhancement of five distinct pathways, and the contents of naringenin-7-O-glucoside, adenosine, pantothenic acid, and D-sucrose decreased after the processing, correlating with decreases in two different pathways. This study provides a comprehensive reference and scientific basis for understanding the health benefits associated with this traditional health food.

RESUMEN

BACKGROUND: Protection from solar ultraviolet radiation (UVR) is paramount in light-skinned pig breeds such as Yorkshire or Landrace to avoid sunburn. OBJECTIVES: Determination of the UVR exposure of a pig and the sun protection abilities of shade cloths with different shade rates. ANIMALS: Life-sized plastic model of a Landrace pig. MATERIALS AND METHODS: The model was equipped with 20 UVR meters at various anatomical positions that recorded the erythemal effective solar irradiance. A turntable enabled irradiation from different directions. Solar irradiance was measured in direct sunlight as well as under three shade cloths with different shade rates (50%, 75% and 90%) and a camouflage net. The sun protection factors (SPF) were determined as the ratio of unshaded-to-shaded measurements at the same solar elevation. The exposure ratio to ambient (ERTA) was calculated for each body site with respect to ambient irradiance. It allows determination of when pigs are at risk of sunburn and protection is needed. RESULTS: The calculated ERTA values show that some body parts may receive higher values than ambient UVR. Measurements showed that the SPF of shade cloths depends on textile denseness. Selected shade cloths reached values of 3.5 (shade rate 50%), 4.2 (75%) and 5.8 (90%). Protection by the camouflage net was poor. The highest SPF was gained on body sides where ERTA was highest. CONCLUSIONS AND CLINICAL RELEVANCE: Shade cloths can protect all body sites effectively and vulnerable sites in particular. The results of our study enable an estimation of when pigs are at risk of sunburn and provide quantitative metrics for sun protection. This allows effective prevention of UVR-caused skin damage and secondary disorders.
