It is estimated that 300,000 children 0-14 years of age are diagnosed with cancer worldwide each year. While the absolute risk of cancer in children is low, it is the leading cause of death due to disease in children in high-income countries. In spite of this, the etiologies of pediatric cancer are largely unknown. Environmental exposures have long been thought to play an etiologic role. However, to date, there are few well-established environmental risk factors for pediatric malignancies, likely due to technical barriers in collecting biological samples prospectively in pediatric populations for direct measurements. In this review, we propose the use of novel or underutilized biospecimens (dried blood spots and teeth) and molecular approaches for exposure assessment (epigenetics, metabolomics, and somatic mutational profiles). Future epidemiologic studies of pediatric cancer should incorporate novel exposure assessment methodologies, data on molecular features of tumors, and a more complete assessment of gene-environment interactions.The objectives of this study were to provide the buffalo research community with an updated SNP map for the Axiom Buffalo Genotyping (ABG) array with genomic positions for SNP currently unmapped and to map all cattle QTL from the CattleQTLdb onto the buffalo reference assembly. To update the ABG array map, all SNP probe sequences from the ABG array were re-aligned against the UOA_WB_1 assembly. With the new map, the number of mapped markers increased by approximately 10% and went from 106 778 to 116 708, which reduced the average marker spacing by approximately 2 kb. CDK phosphorylation A comparison of results between signatures of autozygosity study using the ABG and the new map showed that, when the additional markers were used there was an increase in the autozygosity peaks and additional peaks in BBU5 and BBU11 could be identified. After sequence alignment and quality control, 64 650 (UMD3.1) and 76 530 (ARS_UCD1.2) cattle QTL were mapped onto the buffalo genome. The mapping of the bovine QTL database onto the buffalo genome should be useful for genome-wide association studies in buffalo and, given the high homology between the two species, the positions of cattle QTL on the buffalo genome can serve as a stepping stone towards a water buffalo QTL database.Sampling of healthy multi-rooted teeth is recommended for the genetic identification of human skeletal remains. However, this may not always be possible, as in the reported case consisting of an isolated human cranium found in an aggregate crushing and processing plant in Piedmont, Northwest Italy. The cranium displayed significant weathering, suggesting a post-mortem interval of several years, and was edentulous with the exception of the apical root fragment of the upper left canine, consequence of an antemortem horizontal fracture. Prolonged decalcification of the root fragment followed by powder-free DNA extraction from ~10 mg of root tip tissue led to the recovery of >10 ng of high molecular weight human DNA, in comparison with ~0.01 ng of DNA per mg of bone powder obtained from the petrous portion of the temporal bone. Quantity and quality of DNA isolated from apical tooth tissue enabled multiple genotyping, including a reportable female STR profile, mitochondrial DNA analysis, and ancestry-informative insertion/deletion polymorphisms. Although the cranium remained unidentified after DNA comparisons, our findings confirm that apical tooth tissue is a promising source of DNA, easily obtained through a powder-free extraction protocol. Results also indicate that root tips should not be overlooked in challenging identification cases, even in the presence of compromised tooth specimens.Air pollution is a major global challenge for a multitude of reasons. As a specific concern, there is now compelling evidence demonstrating a causal relationship between exposure to airborne pollutants and the onset of cardiovascular disease (CVD). As such, reducing air pollution as a means to decrease cardiovascular morbidity and mortality should be a global health priority. This review provides an overview of the cardiovascular effects of air pollution and uses two major events of 2020-the Australian bushfires and COVID-19 pandemic lockdown-to illustrate the relationship between air pollution and CVD. The bushfires highlight the substantial human and economic costs associated with elevations in air pollution. Conversely, the COVID-19-related lockdowns demonstrated that stringent measures are effective at reducing airborne pollutants, which in turn resulted in a potential reduction in cardiovascular events. Perhaps one positive to come out of 2020 will be the recognition that tough measures are effective at reducing air pollution and that these measures have the potential to stop thousands of deaths from CVD.

Presence of jaundice in gallbladder carcinoma (GBC) is considered a sign of inoperability with no defined treatment pathways.

Retrospective analysis of all surgically treated GBC patients from January 2010 to December 2019 was performed for evaluating etiology of obstructive jaundice, resectability, postoperative morbidity, mortality, disease-free survival (DFS) and overall survival (OS).

Out of 954 patients, 521 patients (54.61%) were locally advanced gallbladder carcinoma (LAGBC Stage III and IV) and 113 patients (11.84%) had jaundice at presentation. Thirty-four (30%) patients had benign cause of obstructive jaundice. Median OS of the whole cohort (n=113) was 22 months (16.5-27.49 months) with resectability rate of 62% (70/113). Median OSof curative resection group (n=70) was 32 months and DFS was 25 months. Treatment completion was achieved in 30% (n= 21/70) patients with median OS of 46 months and median DFS of 27 months. Isolated bile duct infiltration subgroup fared the best with median OS of 74 months with a 5-year survival of 66.7%.

Surgical resection as a part of multimodality treatment improves survival in carefully selected locally advanced gallbladder cancer patients with jaundice. Early introduction of systemic therapy is the key in the management of this disease with aggressive tumor biology.
