Background

Recently, as cumulative exposure of lipids for a lifetime has become important to prevent and predict atherosclerotic cardiovascular disease (ASCVD), it is recommended to obtain the optimal lipid levels from a young age. However, questions remain regarding the vascular changes in young adulthood by nonoptimal lipid levels.

Purpose

We aimed to investigate the progression of coronary artery calcification (CAC) according to lipid profiles in Korean young adults.

Methods

From the KOrea Initiative on Coronary Artery calcification registry, we collected 2,940 statin-naïve adults under 45-year-old, undergoing serial coronary artery calcium scans for the purpose of routine health check-ups between 2002 and 2017. CAC progression was assessed according to the optimality of lipid levels and each lipid variable.

Results

In this cohort (mean age, 41.3 years; man 82.4%), only 477 subjects (16.2%) had the optimal lipid profile, defined as triglycerides <150 mg/dl, LDL cholesterol <100 mg/dl, and HDL cholesterol ≥45 mg/dl. During follow-up (median 39.7 months), CAC progression was observed in 438 participants (14.8%) and more frequent in nonoptimal lipid group (16.5% vs 5.9%; p<0.001). Nonoptimal lipid levels during young adulthood increased the risk of CAC progression after adjusting for other cardiovascular risk factors (adjusted HR, 2.36; p=0.001), with a stepwise risk increase according to lipid levels. In particular, in the subjects with an initial calcium score of zero (adjusted HR, 2.13; p=0.014), those in their 20s or 30s (adjusted HR 2.70; p=0.029), and those without any other risk factors (adjusted HR 2.51; p=0.025), deemed as very low-risk groups, nonoptimal lipid levels more than doubled the risk of CAC progression, respectively. Among lipid variables, high triglycerides appeared to provide the greatest impact on CAC progression of young adults.

Conclusions

The proportion of young adults with optimal lipid levels was lower than expected. Nonoptimal lipid level was significantly associated with the risk of CAC progression in young adults, even with low-risk. Triglycerides had the strongest association with the risk of CAC progression. Screening and intervention for nonoptimal lipid levels, particularly triglycerides, from an early age might be of clinical value.

Resilience-Promoting Programs in Families of Children With Cancer: A Systematic Review

Purpose: Pediatric cancer is a difficult experience for children and their families. It is thus necessary to promote family resilience for the effective treatment and quality of life improvement among children with cancer. The aim of this systematic review was to identify the components of a resilience-promoting program for children with cancer and their families and to synthesize the literature findings on the outcomes of the resilience-promoting program. Method: A systematic search of the literature was conducted using five databases (PubMed, CHIAHL, PsycINFO, Web of Science, and Research Information Sharing Service) up to July 22, 2020. The search was limited to studies published in English and Korean, and to grey literature published in Korea. Studies were critically appraised using the Mixed Methods Appraisal Tool and Cochrane Risk of Bias tool. Extracted data were summarized as tables. Results: Eight studies were selected. The main components of the resilience-promoting program were providing information (on strategies, medical and psychoeducation, and community resources) and emotional coping (expressing feeling, reappraising cognition about adversity, and stress management). The main outcomes of these programs were reinforced outcomes (resilience, benefit finding, coping, positive affect, problem-solving skills, family adaptation, and self-concept) and improved outcomes (in depression, posttraumatic stress, anxiety, impact of illness of the family, and mood). Conclusion: As the components and outcomes of family resilience-promoting programs vary, it is necessary to consistently use valid tools to effectively identify interventions. Additionally, various methodological studies are required to further analyze the effect of these programs.

Risk of Psoriasis among Survivors of Adult-onset Cancer: A Nationwide Population-based Cohort Study

Cancers can now be diagnosed and treated early, and the number of cancer survivors is increasing.¹ In addition to survival, management of chronic diseases among cancer survivors has emerged as a major concern, because survivors experience numerous sequelae and age-related conditions.² Psoriasis is a chronic inflammatory skin disorder that affects approximately 2-4% of the general population worldwide, and a recent population-based study found that the risk of cancer was higher in psoriasis patients compared to controls.³ Conversely, one report found that the risk of psoriasis in breast cancer patients was higher than in those who were generally healthy.⁴ However, the incidence of psoriasis in survivors of various types of cancer has received little attention.

Systemic armed oncolytic and immunologic therapy for cancer with JX-594, a targeted poxvirus expressing GM-CSF

Targeted oncolytic viruses and immunostimulatory therapeutics are being developed as novel cancer treatment platforms. These approaches can be combined through the expression of immunostimulatory cytokines from targeted viruses, including adenoviruses and herpesviruses. Although intratumoral injection of such viruses has been associated with tumor growth inhibition, eradication of distant metastases was not reported. The major limitations for this approach to date have been (1) inefficient intravenous virus delivery to tumors and (2) the lack of predictive, immunocompetent preclinical models. To overcome these hurdles, we developed JX-594, a targeted, thymidine kinase(-) vaccinia virus expressing human GM-CSF (hGM-CSF), for intravenous (i.v.) delivery. We evaluated two immunocompetent liver tumor models: a rabbit model with reproducible, time-dependent metastases to the lungs and a carcinogen-induced rat liver cancer model. Intravenous JX-594 was well tolerated and had highly significant efficacy, including complete responses, against intrahepatic primary tumors in both models. In addition, whereas lung metastases developed in all control rabbits, none of the i.v. JX-594-treated rabbits developed detectable metastases. Tumor-specific virus replication and gene expression, systemically detectable levels of hGM-CSF, and tumor-infiltrating CTLs were also demonstrated. JX-594 holds promise as an i.v.-delivered, targeted virotherapeutic. These two tumor models hold promise for the optimization of this approach.
