We aimed at molecularly dissecting the anatomical heterogeneity of small lymphocytic lymphoma (SLL), by analysing a cohort of 12 patients for whom paired DNA from a lymph node biopsy and circulating cells, as well as plasma-circulating tumour DNA (ctDNA) was available. Notably, the analyses of the lymph node biopsy and of circulating cells complement each other since a fraction of mutations (20·4% and 36·4%, respectively) are unique to each compartment. Plasma ctDNA identified two additional unique mutations. Consistently, the different synchronous sources of tumour DNA complement each other in informing on driver gene mutations in SLL harbouring potential prognostic and/or predictive value.A patient with a 6-year-old left upper arm brachial cephalic AVF presented with symptoms of hemodialysis access-induced distal ischemia (HAIDI). Physical exam findings showed a well-developed AVF, but compression of the AVF aggravated arm pain and induced diffuse erythema of the left upper extremity. Angiographic evaluation disclosed the presence of a large axillary artery vascular malformation (AVM) as well as distal forearm hypo-perfusion. We elected to publish this case report to describe the interesting physical exam findings related to the AVM, and discuss HAIDI treatment options that are peculiar to this case. We also highlight the importance of thorough vascular evaluation prior to AV access creation as well as during the investigation of the cause of HAIDI.

Mesenchymal cells' biology has been an important investigative tool to maximize bone regeneration through tissue engineering. Here we used mesenchymal cells from periodontal ligament (PDLCs) with high (h-) and low (l-) osteogenic potential, isolated from different donors, to investigate the impact of the individual epigenetic and transcriptional profiles on the osteogenic potential.

Genome-wide and gene-specific DNA (hydroxy) methylation, mRNA expression and immunofluorescence analysis were carried out in h- and l-PDLCs at DMEM (non-induced to osteogenesis) and OM (induced-3rd and 10th days of osteogenic differentiation) groups in vitro.

Genome-wide results showed distinct epigenetic profile among PDLCs with most of the differences on 10th day of OM; DMEMs showed higher concentrations (xOM) of differentially methylated probes in gene body, intronic and open sea (3rd day), increasing this concentration in TSS200 and island regions, at 10 days. At basal levels, h- and l-PDLCs showed different transcriptiodonors' characteristics have significant impact on the osteogenic phenotype acquisition.

This explanatory research aims to describe the factors that impact YouTube ad intrusiveness, value, and avoidance in light of psychological reactance theory.

The research has a causal-predictive design. It describes the relationship between the construct with an underpinning theory. Data from a sample of 294 respondents were analyzed using partial least square structural equation modeling to test within sample explanatory power and out-of-sample prediction power.

The results show that informativeness does not significantly impact intrusiveness and ad avoidance. Entertainment has a negative direct and mediated impact on ad avoidance. Moreover, irritation was found to moderate the impact of informativeness on intrusiveness negatively. Importance-Performance Map Analysis revealed that entertainment lacks in performance despite being an essential factor. Besides explanatory power, the model has a moderate out-of-sample predictive relevance power.

The relative importance of the entertainment and interactive impact of irritation with informativeness is established for the first time in this study. The new finding is a significant contribution to theory while leading to practical implications for the industry.

The coronavirus (COVID-19) pandemic led to disruptions in operative and hospital capabilities as the country triaged resources and canceled elective procedures. This study details the operative experience of a safety-net hospital for cancer-related operations during a 3-month period at the height of the pandemic.

Patients operated on for or diagnosed with malignancies of the abdomen, breast, skin, or soft-tissue (September 3, 2020-September 6, 2020) were identified from operative/clinic schedules. Sociodemographics, tumor and treatment characteristics, and COVID-19 information was identified through retrospective chart review of a prospectively maintained database. NDI091143 Descriptive statistics were calculated.

Fifty patients evaluated within this window underwent oncologic surgery. Median age was 61 (interquartile range 53-68), 56% were female, 86% were White, and 66% were Hispanic. The majority (28%) were for colon cancer. Only two patients tested positive for COVID-19 preoperatively or within 30 days of their operation. There were no mortalities during the 1-year study period.

During the COVID-19 pandemic, many hospitals and operative centers limited interventions to preserve resources, but oncologic procedures continued at many large-volume academic cancer centers. This study underscores the importance of continuing to offer surgery during the pandemic for surgical oncology cases at safety-net hospitals to minimize delays in time-sensitive oncologic treatment.

The well-differentiated rectal neuroendocrine tumors (RNETs) can also have lymph node metastasis (LNM). Large multicenter data were reviewed to explore the risk factors for LNM in RNETs. Further, we developed a model to predict the risk of LNM in RNETs.

In total, 223 patients with RNETs from the Fujian Medical University Union Hospital, the First Affiliated Hospital of Fujian Medical University, and the First Affiliated Hospital of Xiamen University were retrospectively enrolled. Logistic regression analysis was performed to study the factors affecting LNM, and recursive partitioning analysis (RPA) was performed to stratify the risk of LNM.

Among the 223 patients diagnosed with RNETs, the incidence of LNM was 10.8%. Univariate and multivariate regression analyses revealed that tumor size, World Health Organization (WHO) grade, and depth of tumor invasion were independent risk factors for LNM (p < 0.05). The area under the curve was 0.948 (95% confidence interval 0.890-1.000). Furthermore, the incidence of LNM in patients divided into low- and high-risk groups according to RPA was 1.
