This paper describes results from a systematic review and a series of meta-analyses of nearly three decades worth of epidemiologic research on the relationship between non-Hodgkin lymphoma (NHL) and occupational exposure to agricultural pesticide active ingredients and chemical groups. Estimates of associations of NHL with 21 pesticide chemical groups and 80 active ingredients were extracted from 44 papers, all of which reported results from analyses of studies conducted in high-income countries. Random effects meta-analyses showed that phenoxy herbicides, carbamate insecticides, organophosphorus insecticides and the active ingredient lindane, an organochlorine insecticide, were positively associated with NHL. In a handful of papers, associations between pesticides and NHL subtypes were reported; B cell lymphoma was positively associated with phenoxy herbicides and the organophosphorus herbicide glyphosate. Diffuse large B-cell lymphoma was positively associated with phenoxy herbicide exposure. Despite compelling evidence that NHL is associated with certain chemicals, this review indicates the need for investigations of a larger variety of pesticides in more geographic areas, especially in low- and middle-income countries, which, despite producing a large portion of the world’s agriculture, were missing in the literature that were reviewed.

Malnutrition refers to a person’s status as under- or overnourished, and it is usually associated with an inflammation status, which can subsequently imply a different health status, as the risk of infection is increased, along with a deterioration of the immune system. Children’s immune systems are generally more susceptible to problems than adults. In the situation of malnutrition, because malnourished children’s immune systems are compromised, they are more likely to die. However, little is known about the underlying mechanism of altered immune functioning and how it relates to starvation. Nutritional interventions have been reported as cost-effective strategies to prevent or treat the development of malnourishment, considering the link between food intake and health, especially in children, and also the susceptibility of this population to diseases and how their health status during childhood might affect their long-term physiological growth. The ingestion of specific nutrients (e.g., vitamins or oligoelements) has been reported to contribute to the proper functioning of children’s immune systems. In this review, we aim to describe the basis of malnutrition and how this is linked to the immune system, considering the role of nutrients in the modulation of the immune system and the risk of infection that can occur in these situations in children, as well as to identify nutritional interventions to improve their health.

This study was conducted to assess the clinical spectrum, management, and outcome of SARS-CoV-2-related multisystem inflammatory syndrome in children (MIS-C). We reviewed medical records of children with MIS-C diagnosis seen at the Children’s Hospital of Michigan in Detroit between April and June 2020. Thirty-three children were identified including 22 who required critical care (group 1) and 11 with less intense inflammation (group 2). Children in group 1 were older (median 7.0 years) than those in group 2 (median 2.0 years). Abdominal pain was present in 68% of patients in group 1. Hypotension or shock was present in 17/22 patients in group 1. Thirteen (39.4%) had Kawasaki disease (KD)–like manifestations. Five developed coronary artery dilatation; All resolved on follow-up. Intravenous immunoglobulin (IVIG) was given to all patients in group 1 and 7/11 in group 2. Second-line therapy was needed in 13/22 (group 1) for persisting inflammation or myocardial dysfunction; 12 received infliximab. All patients recovered.Conclusion: MIS-C clinical manifestations may overlap with KD; however, MIS-C is likely a distinct inflammatory process characterized by reversible myocardial dysfunction and rarely coronary artery dilatation. Supportive care, IVIG, and second-line therapy with infliximab were associated with a favorable outcome.What is Known:• Multisystem inflammatory syndrome in children (MIS-C) manifestations include fever, gastrointestinal symptoms, shock, and occasional features of Kawasaki disease (KD).• Treatment includes immunomodulatory agents, most commonly IVIG and corticosteroids.What is New:• Spectrum of MIS-C varies from mild to severe inflammation and coronary artery dilatation occurred in 5/22 (23%) critically ill patients.• IVIG and infliximab therapy were associated with a favorable outcome including resolution of coronary dilatation; only 2/33 received corticosteroids.

Recently, numerous side effects of synthetic drugs have lead to using medicinal plants as a reliable source of new therapy. Pain is a global public health problem with a high impact on life quality and a huge economic implication, becoming one of the most important enemies in modern medicine. The medicinal use of plants as analgesic or antinociceptive drugs in traditional therapy is estimated to be about 80% of the world population. The Lamiaceae family, one of the most important herbal families, incorporates a wide variety of plants with biological and medical applications. In this study, the analgesic activity, possible active compounds of Lamiaceae genus, and also the possible mechanism of actions of these plants are presented. The data highlighted in this review paper provide valuable scientific information for the specific implications of Lamiaceae plants in pain modulation that might be used for isolation of potentially active compounds from some of these medicinal plants in future and formulation of commercial therapeutic agents.

Objective Over 20 experts on economics, epidemiology, public policy and tobacco control were asked by the International Agency for Research on Cancer (IARC) to evaluate the strength of the available evidence on the effects of tax and price policies to prevent and reduce tobacco use. Methods Draft papers presenting and assessing the evidence on the following topics were developed by the experts in an 8-month period prior to the meeting: tobacco industry pricing strategies and tax related lobbying; tax, price and aggregate demand for tobacco; tax, price and adult tobacco use, use among young people and use among the poor; tax avoidance and tax evasion; and the economic and health impact of tobacco taxation. Subsequently, papers were peer reviewed, revised and resubmitted for final discussion at a 6-day meeting at IARC in Lyon, France, where a consensus evaluation of 18 concluding statements using the pre-established criteria of the IARC Cancer Prevention Handbooks took place. Studies published (or accepted for publication) in the openly available scientific literature were the main source of evidence for the review and evaluation; other types of publications were included when appropriate. Results In support of 12 of the 18 conclusions, the experts agreed that there was sufficient evidence of effectiveness of increased tobacco excise taxes and prices in reducing overall tobacco consumption and prevalence of tobacco use and improvement of public health, including by preventing initiation and uptake among young people, promoting cessation among current users and lowering consumption among those who continue to use. For the remaining six concluding statements the evidence was strong (four statements) or limited (two statements). Conclusions The evidence presented and assessed in IARC Handbook volume 14 documents the effectiveness of tax and price policies in the control of tobacco use and improvement of public health.

In a review of strategies for preventing oral cancer, an expert panel reports that the use of tobacco (both smoking and smokeless), areca nut exposure, and heavy alcohol consumption are major contributors to this illness.

Phenolic compounds with antioxidant properties have risen in interest due to their benefits for human health. Fragaria chiloensis is a native wild berry species from Chile that develops a white/pink receptacle and white flesh at the ripe stage. Changes in color parameters, anthocyanins, secondary metabolites (phenolics, flavonoids), and total antioxidant capacity were followed during the development and ripening of F. chiloensis fruit. The increment in color ‘a’ index takes place in parallel with anthocyanins rise and the reduction in phenolics, flavonoids, and antioxidant capacity. Good correlations were determined between color development, anthocyanins, and the expression of key phenylpropanoid/flavonoid and anthocyanin pathway genes. To investigate the role of ABA on color development, detached immature fruit (C2 stage) were treated with exogenous ABA and stored at 20 °C. Fruit color development was accelerated by ABA treatment compared to non-treated fruit, and consistent with that, the increment in the accumulation of anthocyanins and transcripts of phenylpropanoid/flavonoid, and anthocyanin pathways genes such as FcPAL, FcCHS, and FcANS were observed. This suggests that ABA promotes transcriptional changes that lead to the color formation on this non-climacteric fruit.

Despite abundant evidence demonstrating that platelets foster metastasis, anti-platelet agents have low therapeutic potential due to the risk of hemorrhages. In addition, whether platelets can regulate metastasis at the late stages of the disease remains unknown. In this study, we subject syngeneic models of metastasis to various thrombocytopenic regimes to show that platelets provide a biphasic contribution to metastasis. While potent intravascular binding of platelets to tumor cells efficiently promotes metastasis, platelets further support the outgrowth of established metastases via immune suppression. Genetic depletion and pharmacological targeting of the glycoprotein VI (GPVI) platelet-specific receptor in humanized mouse models efficiently reduce the growth of established metastases, independently of active platelet binding to tumor cells in the bloodstream. Our study demonstrates therapeutic efficacy when targeting animals bearing growing metastases. It further identifies GPVI as a molecular target whose inhibition can impair metastasis without inducing collateral hemostatic perturbations. It is unclear if platelets regulate the growth of established metastases. Using syngeneic mouse models of metastasis, the authors show that platelets support the outgrowth of established metastases via immune suppression, and that targeting the platelet-specific receptor GPVI, efficiently reduces established metastases, providing a promising therapeutic avenue for inhibiting cancer metastasis.

ObjectiveThis study aimed to quantify the long-term impact of implementing the WHO Framework Convention on Tobacco Control (FCTC) compliant tobacco control measures, MPOWER, on smoking prevalence and mortality in men and women aged ≥20 years in Japan.DesignA Stock-and-Flow simulation model was used to project smoking prevalence and mortality from 2018 to 2050 under eight different scenarios: (1) maintaining the 2018 status quo, (2) implementation of smoke-free policies, (3) tobacco use cessation programmes, (4–5) health warning about the dangers of tobacco (labels, mass media), (6) enforcement of tobacco advertising bans or (7) tobacco taxation at the highest recommended level and (8) all these interventions combined.ResultsUnder the status quo, the smoking prevalence in Japan will decrease from 29.6% to 15.5% in men and 8.3% to 4.7% in women by 2050. Full implementation of MPOWER will accelerate this trend, dropping the prevalence to 10.6% in men and 3.2% in women, and save nearly a quarter million deaths by 2050. This reduction implies that Japan will only attain the current national target of 12% overall smoking prevalence in 2033, 8 years earlier than it would with the status quo (in 2041), a significant delay from the national government’s 2022 deadline.ConclusionsTo bring forward the elimination of tobacco smoking and substantially reduce smoking-related deaths, the government of Japan should fulfil its commitment to the FCTC and adopt stringent tobacco control measures delineated by MPOWER and beyond.

Satellite DNA (satDNA) is a major component yet the great unknown of eukaryote genomes and clearly underrepresented in genome sequencing projects. Here we show the high-throughput analysis of satellite DNA content in the migratory locust by means of the bioinformatic analysis of Illumina reads with the RepeatExplorer and RepeatMasker programs. This unveiled 62 satDNA families and we propose the term “satellitome” for the whole collection of different satDNA families in a genome. The finding that satDNAs were present in many contigs of the migratory locust draft genome indicates that they show many genomic locations invisible by fluorescent in situ hybridization (FISH). The cytological pattern of five satellites showing common descent (belonging to the SF3 superfamily) suggests that non-clustered satDNAs can become into clustered through local amplification at any of the many genomic loci resulting from previous dissemination of short satDNA arrays. The fact that all kinds of satDNA (micro- mini- and satellites) can show the non-clustered and clustered states suggests that all these elements are mostly similar, except for repeat length. Finally, the presence of VNTRs in bacteria, showing similar properties to non-clustered satDNAs in eukaryotes, suggests that this kind of tandem repeats show common properties in all living beings.
