    BACKGROUND: Understanding the magnitude of cancer burden attributable to potentially modifiable risk factors is crucial for development of effective prevention and mitigation strategies. We analysed results from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019 to inform cancer control planning efforts globally. METHODS: The GBD 2019 comparative risk assessment framework was used to estimate cancer burden attributable to behavioural, environmental and occupational, and metabolic risk factors. A total of 82 risk–outcome pairs were included on the basis of the World Cancer Research Fund criteria. Estimated cancer deaths and disability-adjusted life-years (DALYs) in 2019 and change in these measures between 2010 and 2019 are presented. FINDINGS: Globally, in 2019, the risk factors included in this analysis accounted for 4·45 million (95% uncertainty interval 4·01–4·94) deaths and 105 million (95·0–116) DALYs for both sexes combined, representing 44·4% (41·3–48·4) of all cancer deaths and 42·0% (39·1–45·6) of all DALYs. There were 2·88 million (2·60–3·18) risk-attributable cancer deaths in males (50·6% [47·8–54·1] of all male cancer deaths) and 1·58 million (1·36–1·84) risk-attributable cancer deaths in females (36·3% [32·5–41·3] of all female cancer deaths). The leading risk factors at the most detailed level globally for risk-attributable cancer deaths and DALYs in 2019 for both sexes combined were smoking, followed by alcohol use and high BMI. Risk-attributable cancer burden varied by world region and Socio-demographic Index (SDI), with smoking, unsafe sex, and alcohol use being the three leading risk factors for risk-attributable cancer DALYs in low SDI locations in 2019, whereas DALYs in high SDI locations mirrored the top three global risk factor rankings. From 2010 to 2019, global risk-attributable cancer deaths increased by 20·4% (12·6–28·4) and DALYs by 16·8% (8·8–25·0), with the greatest percentage increase in metabolic risks (34·7% [27·9–42·8] and 33·3% [25·8–42·0]). INTERPRETATION: The leading risk factors contributing to global cancer burden in 2019 were behavioural, whereas metabolic risk factors saw the largest increases between 2010 and 2019. Reducing exposure to these modifiable risk factors would decrease cancer mortality and DALY rates worldwide, and policies should be tailored appropriately to local cancer risk factor burden

    SnO2 NPs were successfully prepared via a hydrothermal method. X-ray diffraction analysis confirmed the rutile tetragonal structure of SnO2 NPs. The crystallite size increased from 1.18 to 5.06 nm with increasing the preparation temperature from 100 to 180 °C. The SEM photography of the products exhibited the agglomeration of the SnO2 nanocrystals to large view particles, while TEM images confirmed the polycrystalline phase and crystallite size those analyzed from XRD. The UV–vis absorption of ethanol suspended SnO2 NPs was measured. The optical band-gap energies (Eg) were significantly blue-shifted due to quantum confinement. Fluorescence spectra came to confirm this shift, where a clear shift in the maximum emission peak was observed. Stokes shift of SnO2 nanocrystals was found to be crystallite size dependent

    Background: Lack of adequate tobacco-related content in pharmacy curricula can interfere with pharmacist's ability to provide tobacco cessation interventions. This study aims to determine the extent of tobacco-related content in pharmacy schools' curricula across the Middle East region, instructional methods used, perceived adequacy and importance of tobacco education, and barriers for inclusion of tobacco-related content in pharmacy curricula. Methods: A web-based survey was sent to 120 schools of pharmacy in 13 Middle Eastern countries. Key faculty members were identified and sent an e-mail with an online link to the survey. Data were descriptively analyzed using Statistical Package for Social Sciences version 22. Results: Of the 120 pharmacy schools contacted, 59 schools completed the survey (49.2% response rate). Of this, 44 (74.6%) reported including tobacco-related content in their undergraduate curricula. Nicotine pharmacology and principles of addiction (64.4%), pharmacologic aids for tobacco cessation (61%), and health effects of tobacco (61%) were the most commonly reported topics. The topics that were least perceived to be adequately covered were monitoring outcomes of tobacco cessation interventions (5.9%) and epidemiology of tobacco use (15.4%). The top barriers to inclusion of tobacco-related topics in the curriculum were lack of time (75.9%), lack of experiential training sites focusing on tobacco cessation interventions (72.2%), lack of faculty expertize (66%), and perceived lack of priority of tobacco related content in pharmacy schools (66%). Conclusions: The current findings suggest that more efforts should be geared towards increasing content for tobacco education in schools of pharmacy across the Middle East and towards overcoming the identified barriers. Implications: This study is the first to assess the extent of tobacco-related content in pharmacy schools curricula across the Middle East countries. If pharmacy students are expected to deliver effective tobacco cessation services when they graduate as pharmacists, then schools of pharmacy in the Middle East should consider providing adequate tobacco-related content and training in undergraduate curricula. Pharmacy schools have to work on circumventing the identified barriers including lack of time, lack of experiential training sites offering tobacco cessation interventions, shortage of faculty with relevant expertize and placing low priority on tobacco education in pharmacy schools. - The Author(s) 2017.

    Dyslipidemia is a risk factor for cardiovascular disease, steatohepatitis, and progression of liver disorders. This study investigated the protective effect of farnesol (FAR), a sesquiterpene alcohol, against liver injury in high cholesterol diet (HCD)-fed rats, and its modulatory effect on fatty acid synthase (FAS) and acetyl-CoA carboxylase (ACC). HCD was supplemented for 10 weeks, and the rats were concurrently treated with FAR. Rats that received HCD exhibited significant elevation of serum cholesterol, triacylglycerols, LDL and vLDL cholesterol, CRP, and pro-inflammatory cytokines and increased values of the cardiovascular risk indices. Serum transaminases, ALP, LDH and CK-MB, and hepatic lipid peroxidation (LPO), cholesterol, and triacylglycerols were increased in HCD-fed rats. Treatment with FAR greatly ameliorated dyslipidemia and liver function, reduced inflammatory mediators, LPO, and hepatic lipid infiltration and enhanced anti-oxidant defenses. FAR suppressed hepatic FAS, ACC, and SREPB-1c mRNA abundance and FAS activity in HDC-fed rats. In addition, molecular docking simulations pinpointed the binding modes of FAR to the active pocket residues of FAS and ACC. In conclusion, FAR possesses a strong anti-hyperlipidemic/anti-hypercholesterolemic activity mediated through its ability to modulate hepatic FAS, ACC, and SREPB-1c. FAR prevented oxidative stress, inflammation, and liver injury induced by HCD. Thus, FAR may represent a promising lipid-lowering agent that can protect against dyslipidemia and its linked metabolic deregulations
