The purpose of this study was to compare the differences of arrhythmogenic substrate using high-density mapping in ventricular tachycardia (VT) patients with ischemic (ICM) vs non-ischemic cardiomyopathy (NICM).

Data from patients presenting for VT ablation from December 2016 to December 2020 at Westmead Hospital were reviewed.

Sixty consecutive patients with structural heart disease (ICM 57%, NICM 43%, mean age 66years) having catheter ablation of scar-related VT with pre-dominant left ventricular involvement were included. ICM was associated with larger proportion of dense scar area (bipolar; 19 [12-29]% vs 6 [3-10]%, P < 0.001, unipolar; 20 [12-32]% vs 11 [7-19]%, P = 0.01) compared with NICM. However, the scar ratio (unipolar dense scar [%]/bipolar dense scar [%]) was significantly higher in NICM patients (1.2 [0.8-1.7] vs 1.7 [1.3-2.3], P = 0.003). Larger scar area in ICM was paralleled by higher proportion of complex electrograms (6 [2-13] % vs 3 [1-5] %, P = 0.01), longer and wider voltage basstive the extent of epicardial/intramural substrate, with paucity of substrate targets for ablation, which results in the worse outcomes with ablation.

The purpose of this study is to evaluate the relationship between body composition, basal metabolic rate (BMR), and serum concentrations of leptin with long-term weight regain after Roux-en-Y gastric bypass (RYGB) and compare it with obesity before surgery.

Prospective longitudinal analytical study. Three groups were formed individuals 60months post RYGB, with weight regain (G1) and without it (G2), and individuals with obesity who had not undergone bariatric surgery (G3). Body fat (BF), body fat mass (BFM), visceral fat (VF), fat-free mass (FFM), skeletal muscle mass (SMM), and BMR were assessed by octapolar and multi-frequency electrical bioimpedance. Fasting serum concentrations of leptin were measured.

Seventy-two individuals were included, 24 in each group. Higher means of BF, BFM, VF, and leptin levels were observed in G1, when compared to G2 (BF 47.5 ± 5.6 vs. 32.0 ± 8.0, p < 0.05; FBM 47.8 ± 11.6 vs. 23.9 ± 7.0, p < 0.05; VF 156.8 ± 30.2 vs. 96.1 ± 23.8, p < 0.05; leptin 45,251.2pg/mL ± 20,071.8 vs. 11,525.7pg/mL ± 9177.5, p < 0.000). G1 and G2 did not differ in FFM, SMM, and BMR. G1 and G3 were similar according to BF, FFM, BMR, and leptin levels. Body composition, but not leptin, was correlated with %weight regain in G1 (FBM r = 0.666, p < 0.000; BF r = 0.428, p = 0.037; VF r = 0.544, p = 0.006).

Long-term weight regain after RYGB is similar to pre-surgical obesity in body composition, BMR, and leptin concentrations, indicating relapse of metabolic and hormonal impairments associated with excessive body fat.

Intragastric balloon (IGB) has been proposed for weight loss before bariatric surgery to reduce surgical risks but its efficacy remains unclear. We conducted a systematic review and meta-analysis of the effectiveness of IGB as bridging therapy and assess potential complications. Amongst 2419 citations, 13 studies were included. IGB resulted in a BMI reduction of 6.60 kg/m2 (MD=6.60, 95% CI 5.06-8.15; I2=72%). The total post-procedural complication rate was 8.13% (95% CI 4.04-13.17%), with majority being balloon intolerance. Overall, IGB is effective as a bridging therapy with adequate procedural safety profile, but further study is needed to evaluate the risk reduction for bariatric surgery and long-term weight-loss outcomes.The U.S. Department of Housing and Urban Development (HUD) BUILD Las Vegas 2019 event brought together Las Vegas Lead Hazard Control and Healthy Homes Program (LVLHCHHP) staff, community leaders, and volunteers from multiple organizations for a neighborhood clean-up and community resource fair in a low-income, historic west Las Vegas neighborhood. In preparation for the event, LVLHCHHP staff encountered a lack of published guidance regarding past BUILD events or planning of community-based public health events. To address this gap in the literature, this brief report offers lessons learned from the process of planning and evaluating the HUD BUILD Las Vegas 2019 event. These include taking early planning measures, centering the focus on community needs, and forming strategic partnerships, which can provide a valuable foundation for future events that want to integrate community engagement with public health.Rainbow trout (Oncorhynchus mykiss) is one of the most economically important cold-water farmed species in the world, and transcriptomic studies in response to heat stress have been conducted and will be studied in depth. Alternative splicing (AS), a post-transcriptional regulatory process that regulates gene expression and increases proteomic diversity, is still poorly understood in rainbow trout under heat stress. In the present study, 18,623 alternative splicing events were identified from 9936 genes using RNA transcriptome sequencing technology (RNA-Seq) and genomic information. A total of 2731 differential alternative splicing (DAS) events were found among 2179 differentially expressed genes (DEGs). Gene ontology analysis revealed that the DEGs were mainly enriched in cellular metabolic process, cell part, and organic cyclic compound binding under heat stress. BI-4020 datasheet Kyoto Encyclopedia of Genes and Genomes pathway enrichment analysis displayed that the DEGs were enriched for 39 pathways, and some key pathways, such as lysine degradation, are involved in the regulation of heat stress in liver tissues of rainbow trout. The results were validated by qRT-PCR, confirming reliability of our bioinformatics analysis.This study aims to evaluate the impact of red LED irradiation on the viability, proliferation, colonogenic potential, markers expression along with osteogenic and chondrogenic differentiation of dental pulp stem cells. DPSCs were isolated from sound human permanent teeth using enzymatic digestion method and seeded with regular culture media. Cells at P4 were irradiated using red LED Light (627 nm, 2 J/cm2) and examined for growth kinetics, and multilineage differentiation using the appropriate differentiation media. The irradiated groups showed an increase in cellular growth rates, cell viability, clonogenic potential, and decrease in population doubling time compared to the control group. Cells of the irradiated groups showed enhanced differentiation towards osteogenic and chondrogenic lineages as revealed by histochemical staining using alizarin red and alcian blue stains. Photobiomodulation is an emerging promising element of tissue engineering triad besides stem cells, scaffolds, and growth factors.Our study aimed to study the efficacy of ILIB on periodontal parameters and glycemic control in patients with periodontitis and type II diabetes. Twenty-one patients in a randomized clinical trial were divided into 2 groups control group (CG), conventional periodontal therapy, and test group (TG), conventional periodontal treatment associated with 10 laser applications by the ILIB-Modified (ILIB-M) technique. Fasting blood glucose levels and glycated hemoglobin (HbA1c), visible plaque index (VPI), gingival bleeding index (GBI), and periodontal clinical parameters were evaluated at baseline and after 4 months (T4). Regarding periodontal parameters, the intragroup analysis showed a statistically significant reduction (p  0.05). The Modified ILIB did not improve the periodontal clinical parameters and glycemic control in patients with type II diabetes.

Conventional chemotherapies are a mainstay for metastatic breast cancers, though durable response is rare. Immunotherapies promise long-term responses thorough immune activation but have been underwhelming in breast cancer relative to other cancer types. Here, we review the mechanisms of existing strategies including chemotherapies and how they may cause breast cancers to become immunogenic to identify potential biomarkers for combinations of conventional and immunotherapies.

Mechanistic considerations should inform biomarker development and patient selection for therapeutic combinations of drugs to combine with immune-checkpoint inhibitors.

The role of surgery with curative intent in HER2+ de novo metastatic breast cancer (dnMBC) is uncertain in the era of dual antibody therapy. We sought to determine from existing retrospective data current practice patterns and if an association exists between surgery to the primary tumor and improved survival in HER2+ dnMBC patients treated with dual anti-HER2 blockade, accounting for selection bias.

This study employed data from the National Cancer Database (NCDB) from the years 2013 to 2015. Study inclusion was limited to adult women with HER2+ dnMBC, who received immunotherapy/biologic response modifier drugs (BRM) as a first line treatment. Patients who received both systemic therapy and surgery to the primary breast tumor and patients who received systemic therapy alone were analyzed in two groups. Chi-square test for discrete variables and Wilcox on Rank-Sum test for numeric variables was used to compare the two groups based on patient, tumor, and treatment characteristics. The primary endpoint was the era of dual antibody therapy, patients who underwent surgery had a superior 3-year survival rate than those who did not. There may be a role for a prospective trial in HER2+ dnMBC patients with an excellent response to dual HER2 blockade to investigate the contribution of curative intent local therapy to the primary tumor compared to systemic therapy alone.This study assessed the HIV prevalence among MSM in the greater Newark New Jersey area including Essex, Hudson, Morris and Union Counties and examined correlates of HIV infection among those men. By analyzing National HIV Behavioral Surveillance data on MSM from four counties in New Jersey (N = 175), which were collected via a venue-based sampling method in 2017, this study shows that HIV prevalence among all races/ethnicities (12.5-31.9%) and all age groups (15.1-47.8%) were high. Casual sex and unprotected sex with male partners were prevalent among these men, regardless of HIV test results. MSM who were tested HIV positive were more likely to have diagnosed any sexual transmitted diseases in the last 12 months (AOR 6.7; 95% CI 2.2, 21.3) and less likely to have had alcohol use in the past 12 months (AOR 0.3; 95% CI 0.1, 0.8). Findings from behavioral surveillance strengthens the response to the HIV epidemic by providing policy makers and care/prevention providers with peer reviewed data to base their decisions on.The purpose of this study is to emphasize the imaging features of complications of gallstones beyond the cystic duct on ultrasound (US), enhanced and nonenhanced computed tomography (CECT and NECT), magnetic resonance imaging (MRI), magnetic resonance cholangiopancreatography (MRCP), and endoscopic retrograde cholangiopancreatography (ERCP). This article includes a brief overview of gallstone imaging and emerging trends in the detection of gallstones. This review article will highlight complications of gallstones, including choledocholithiasis, gallstone pancreatitis, acute cholangitis, Mirizzi syndrome, cholecystobiliary and cholecystoenteric fistulas, and gallstone ileus. Imaging findings and limitations of US, CT, MRI, and ERCP will be discussed. The review article will also briefly discuss the management of each disease. The presence of gallstones beyond the level of the cystic duct can lead to a spectrum of diseases, and emergency radiologists play a critical role in disease management by providing a timely diagnosis.
