Congenital Heart Diseases: Genetic Risk Variants and Their Methylation Status.

(1) Background: The interaction between single nucleotide variants (SNVs) associated with congenital heart diseases (CHDs) and their gene methylation status has not been well researched. The aim of the present study was to determine if there is a relationship between the methy lation status (MS) of genes and the allelic variants associated with CHDs. (2) Methods: Seven SNVs of the genes AXIN1, TBX1, TBX20, and MTHFR were selected from the literature. DNA extraction, genotyping, and a methylation analysis were performed on healthy subjects and subjects with CHDs. (3) Results: Twenty-two subjects with CHDs were selected as the case group (15 with ventricular septal defects (VSDs) and 7 with atrial septal defects (ASDs)), and 44 healthy subjects comprised the control group. The MTHFR and AXIN1 genes were hypermethylated in the control group when compared to the case group. When analyzed separately, those with atrial septum defects exhibited greater methylation, except for the gene MTHFR where there were no differences. Only the alternate alleles of MTHFR showed a significantly different methylation status in those without cardiopathy. (4) Conclusions: The MTHFR and AXIN genes were hypermethylated in the control group; however, only the alternate alleles of MTHFR (rs1801133 and rs1801131) showed a significantly different methylation status.

Safety and Efficacy of Lenabasum, a Cannabinoid Receptor Type 2 Agonist, in Patients with Dermatomyositis with Refractory Skin Disease: A Randomized Clinical Trial.

BACKGROUND: Treatment options are limited for skin disease in dermatomyositis. Lenabasum is a cannabinoid receptor type 2 agonist that triggers the resolution of inflammation. OBJECTIVE: The objective of this study was to evaluate the safety and efficacy of lenabasum in patients with refractory cutaneous dermatomyositis. DESIGN: This study was a single-center, double-blind, randomized, placebo-controlled phase 2 study conducted from July 2015 to August 2017. POPULATION: The population included subjects aged ≥18 years with at least moderately active dermatomyositis skin activity by Cutaneous Dermatomyositis Disease Area and Severity Index activity ≥ 14 and failure or intolerance to hydroxychloroquine. INTERVENTION: Participants received 20 mg lenabasum daily for 28 days and then 20 mg twice per day for 56 days or placebo. MAIN OUTCOMES AND MEASURES: The primary outcome was a change in Cutaneous Dermatomyositis Disease Area and Severity Index activity. Safety and other secondary efficacy assessments were performed till day 113. RESULTS: A total of 22 subjects were randomized to lenabasum (n = 11) or placebo (n = 11). No serious or severe adverse events were related to lenabasum, and no participants discontinued the study. The adjusted least-squares mean for Cutaneous Dermatomyositis Disease Area and Severity Index activity decreased more for lenabasum, and the difference was significant on day 113 (least-squares mean [standard error] difference = ‒6.5 [3.1], P = 0.038). Numerically greater improvements were seen in multiple secondary efficacy outcomes and biomarkers with lenabasum. CONCLUSION: Lenabasum treatment was well tolerated and was associated with greater improvement in Cutaneous Dermatomyositis Disease Area and Severity Index activity and multiple efficacy outcomes. TRIAL REGISTRATION: This study was registered at ClinicalTrials.gov, NCT02466243.

Seborrheic Dermatitis in Older Adults: Pathogenesis and Treatment Options.

Seborrheic dermatitis is a common and chronic skin disease, which is particularly prevalent in older adults. While a specific cause of seborrheic dermatitis remains largely unelucidated, the currently understood pathogenesis of seborrheic dermatitis revolves around the presence of Malassezia yeast colonies and an inflammatory response in the affected individual. Keratinocyte proliferation resulting from inflammasome response in the host skin leads to the clinically relevant symptoms of seborrheic dermatitis. The increasing number of older adults as a percentage of the population in the USA will lead to an even higher prevalence of the disease in the ensuing decades. Fortunately, there are multiple treatment options based on individual patient situations and preferences. Topical treatment is the gold standard, but oral therapy may be required in certain cases. In order to maximize effectiveness and minimize adverse pharmacologic effects, effective treatment for older adults must take into account changes in lifestyle and metabolism that occur with aging.

Maternal Folic Acid Intake and Methylation Status of Genes Associated with Ventricular Septal Defects in Children: Case-Control Study.

BACKGROUND: DNA methylation is the best epigenetic mechanism for explaining the interactions between nutrients and genes involved in intrauterine growth and development programming. A possible contributor of methylation abnormalities to congenital heart disease is the folate methylation regulatory pathway; however, the mechanisms and methylation patterns of VSD-associated genes are not fully understood. OBJECTIVE: To determine if maternal dietary intake of folic acid (FA) is related to the methylation status (MS) of VSD-associated genes (AXIN1, MTHFR, TBX1, and TBX20). METHODS: Prospective case-control study; 48 mothers and their children were evaluated. The mothers' dietary variables were collected through a food frequency questionnaire focusing on FA and the consumption of supplements with FA. The MS of promoters of genes was determined in the children. RESULTS: The intake of FA supplements was significantly higher in the control mothers. In terms of maternal folic acid consumption, significant differences were found in the first trimester of pregnancy. Significant differences were observed in the MS of MTHFR and AXIN1 genes in VSD and control children. A correlation between maternal FA supplementation and MS of AXIN1 and TBX20 genes was found in control and VSD children, respectively. CONCLUSIONS: A lower MS of AXIN1 genes and a higher MS of TBX20 genes is associated with FA maternal supplementation.

Analysis of Wait Times and Impact of Real-Time Surveys on Patient Satisfaction.

BACKGROUND: Increasing emphasis is being placed on patient satisfaction, which is linked to reimbursement rates. The Consumer Assessment of Healthcare Providers and Systems (CAHPS) is a national, standardized survey used to assess patient satisfaction. Its limitations include the length of the survey, delay in administration, and generalization to all specialties. Ideal patient satisfaction surveys should collect information in a way that allows for corrective action in a timely manner. OBJECTIVE: To evaluate patient dissatisfaction with wait time using a short, in-office, real-time survey. METHODS: A cross-sectional study in which patients from one provider's office completed a real-time survey. These results were compared with the CAHPS survey data of the same time period. RESULTS: Seven hundred fifty-six patients were seen and 251 surveys were collected. The real-time survey response rate was 33% compared with 9% for the CAHPS survey. Overall, 95.74% of patients who completed the real-time survey were satisfied with their wait times and the duration of their visit, versus 84.2% from the CAHPS survey. CONCLUSION: Implementation of a short in-office survey immediately after patient care can provide better feedback that can be used to ensure that improvement measures are aimed at making significant strides in improving overall health outcomes for patients.
