Here in, we report a case of recurrent left atrial sarcoma which was removed by noteworthy surgical technique.Despite the emergent application of three-dimensional (3D) technology for thoracic reconstructions, reports regarding its use for the resolution of the heterogeneous subgroup of complex chest wall malformations are lacking. We aim to report a novel, standardized process of personalized repair of complex chest wall malformations comprising multidisciplinary, comprehensive surgical planning; surgical simulation on a 3D-printed scale model of the area of interest; manufacturing of customized prostheses; and surgical repair according to plan. We propose this therapeutic strategy for the resolution of such a wide variety of chest wall deformities to reduce improvisation and enhance outcomes.We report the case of a 23-year-old female with recurrent episodes of chest and back pain. A cardiac mass of uncertain etiology was discovered and she was referred to our multi-disciplinary cardiac tumor team. Pathological analysis from the surgical specimen confirmed this mass was a giant aneurysm of the left anterior descending artery. Giant coronary artery aneurysms (GCAAs) have been previously defined as localized coronary artery dilations greater than 20mm. While GCAAs are frequently found in pediatric populations, they are exceedingly rare in adults, with a reported incidence of 0.02-0.2%1, 2. GCAAs can be caused by atherosclerosis, Takayasu arteritis, congenital coronary malformations, or Kawasaki disease3. While these aneurysms are often asymptomatic, they may induce ischemia or lead to an acute myocardial infarction due to disruption of coronary arterial flow from mass effect or luminal thrombosis. In this case, we describe a young woman who presented with chest pain and was found to have a cardiac mass identified pathologically as a GCAA.Oxidative stress-related ocular surface epithelial damage can be initiated by ambient oxygen, UV radiation, and chemical burns. see more The oxidative damage to cornea can lead to inflammation and even vision loss. Lingzhi (Ganoderma lucidum) is a Chinese herbal drug and has been shown to prevent chronic diseases in clinical practices and has been proven to possess anti-oxidative and anti-inflammatory properties. In the study, we prepared poly (lactic-co-glycolic acid) (PLGA) nanoparticles (NPs) as a sustained drug release system of Lingzhi (LZH) to improve bioavailability. The particle size of developed NPs containing LZH (LZH-NPs) was ~184 nm with narrow size distribution. The results of cellular uptake revealed that using NPs as a drug delivery system could significantly increases the intracellular retention time. The results of the cell viability and chemiluminescence assay revealed that 5 μg/ml of LZH-NPs might be the threshold concentration for cultivation of corneal epithelial cells. After treating LZH-NPs in oxidative damaged cells, the results showed that the inflammation-related gene expression and DNA fragmentation level were both significantly decreased. Post-treatment of LZH-NPs in damaged corneal epithelial cells could increase the cell survival rate. In the rabbit corneal alkali burn model, topical instillation of LZH-NPs could promote corneal wound healing and decrease the inflammation. These results suggest that LZH-NPs may have the potential to treat ocular surface diseases caused by oxidative stress.

Bardet-Biedl syndrome is an autosomal recessive disease characterized by rod-cone dystrophy, postaxial polydactyly, kidney defects, obesity, mental retardation and hypogonadism. Here, we report different genotypes in two Bardet-Biedl syndrome affected sisters with a different clinical phenotype regarding severity.

The proband of the family was examined by Next Generation Sequencing (NGS) using clinical exome and filtering by syndromic and non-syndromic genes associated with retinal dystrophies.

Targeted NGS revealed two novel variants in the MKKS and CEP290 genes in homozygosis state in the proband. Segregation analysis revealed the presence of the same MKKS homozygous variant in her younger affected sister but not the CEP290 variant. Both sisters presented different clinical manifestation, at different ages, with a more severe renal and retinal defect in the case of the sister carrying mutations in both genes. Another unaffected sister showed only homozygosity for the CEP290 variant, thus supporting thnt different genotypes and clinical manifestation, suggesting that the novel CEP290 variant could be acting as a modifier, making the phenotype more severe in the sister homozygote for MKKS and CEP290 genes. On the other hand, the difference in the age of both sisters highlight the important role of monitoring disease progression also to confirm the modifier role of genetic variants.

We examined the most important correlates to sleep duration and efficiency from a comprehensive array of multilevel factors.

Baseline data from a cohort of 216 Black/African American smokers aged 40-65 years were examined. The binary outcomes of healthy sleep duration (6-8 h/night) and efficiency (≥85%) were ascertained from 14 consecutive days of actigraphy. Seventy-three independent variables from socio-demographic, individual behavioral, individual physiological, interpersonal, and community domains were assessed. Random survival forest decision trees were generated for each outcome, and variable importance metrics used to rank the predictive abilities of exposure variables. The 5 most predictive exposure variables for each outcome were entered into a regression model of the respective outcome (with age and sex).

Study participants (N=216) had a mean age of 54.57 years (SD=6.17) and 57% were male. Healthy sleep duration was achieved by 56.5% and healthy sleep efficiency by 13.6% of the sample. Regression models showed every additional minute of light physical activity was associated with 1% increased odds, while every unit decrease in the inflammation marker of interleukin-8 was associated with 12% increased odds, of achieving a healthy sleep duration. Every unit increase in total social support was associated with a 34% increased odds, while every unit increase in the hazardous drinking score corresponded with 30% decreased odds, of achieving healthy sleep efficiency.

Light physical activity, social support, and alcohol consumption may be key modifiable intervention targets to improving sleep duration and sleep efficiency in this population.
